HALSEY DRUG CO., INC. 616 N. NORTH COURT, SUITE 120 PALATINE, ILLINOIS 60067 PROXY STATEMENT 2004 ANNUAL MEETING OF SHAREHOLDERS This Proxy Statement is furnished in connection with the solicitation by the Board of Directors of Halsey Drug Co., Inc., doing business as Halsey Pharmaceuticals (the "Company") of proxies in the accompanying form, to be voted at the 2004 Annual Meeting of Shareholders of the Company (the "Meeting") to be held on [ ] , 2004, and at any adjournment(s) thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders. This Proxy Statement and the form of proxy were first mailed to shareholders on or about [ ], 2004. The close of business on [ ], 2004 has been fixed as the record date (the "Record Date") for the determination of shareholders entitled to notice of and to vote at the Meeting. On the Record Date, the Company's outstanding voting securities consisted of [ ] shares of common stock, $.01 par value per share (the "Common Stock"), which is comprised of [ ] shares of Common Stock issued and outstanding and [ ] shares of Common Stock underlying the Company's issued and outstanding 5% convertible senior secured debentures issued by the Company in 1998 and 1999 (including debentures issued in satisfaction of interest payments under such debentures) (collectively, the "1998 and 1999 Debentures") for which the holders of the 1998 and 1999 Debentures are entitled to vote on shareholder matters on an as-converted basis. Under the New York Business Corporation Law and the Company's Certificate of Incorporation and Bylaws, each stockholder will be entitled to one vote for each share of Common Stock held at the Record Date, and each holder and the holders of the 1998 and 1999 Debentures will be entitled to one vote for each share of Common Stock into which such debenture holder's 1998 and 1999 Debentures are convertible at the Record Date, for all matters, including the election of directors. The required quorum for the transaction of business at the Meeting is a majority of the votes eligible to be cast by holders of shares of Common Stock and holders of 1998 and 1999 Debentures issued and outstanding on the Record Date. Shares that are voted "FOR," "AGAINST," "WITHHELD" or "ABSTAIN" are treated as being present at the Meeting for the purposes of establishing a quorum and are also treated as shares entitled to vote at the Meeting (the "Votes Cast") with respect to such matter. Abstentions will have the same effect as voting against a proposal. Broker non-votes will be counted for purposes of determining the presence or absence of a quorum for the transaction of business, but such non-votes will not be counted for purposes of determining the number of Votes Cast with respect to the particular proposal on which a broker has expressly not voted. Thus a broker non-vote will not effect the outcome of the voting on a proposal. Holders of Common Stock and the holders of the 1998 and 1999 Debentures have no cumulative voting rights in the election of directors.

SUMMARY OF THE TRANSACTION FOR THE SALE OF ASSETS LOCATED AT OUR CONGERS, NEW YORK FACILITIES The following summary describes the material terms of the proposed sale of substantially all of the assets located at our Congers, New York locations to IVAX Pharmaceuticals New York LLC ("IVAX"), a wholly-owned subsidiary of IVAX Corporation. This summary does not contain all of the information that may be important for you to consider when evaluating the proposed transaction. We encourage you to read the entire Proxy Statement (including the Asset Purchase Agreement attached as Appendix I) before voting. We have entered into an Asset Purchase Agreement with IVAX, dated March 19, 2004, pursuant to which we will sell and transfer to IVAX substantially all of the assets used in the Company's manufacturing, labeling, packaging, storage, distribution and sale of finished dosage generic pharmaceutical products located at our Congers, New York locations (collectively, the "Congers Assets"). THE PARTIES TO THE ASSET PURCHASE AGREEMENT (SEE PAGE 65) Halsey Drug Co., Inc. 616 N. North Court, Suite 120 Palatine, Illinois 60067 Telephone: (847) 705-7709 Website: www.halseydrug.com The Company is engaged in the development of proprietary opioid synthesis technologies for manufacturing of active pharmaceutical ingredients ("APIs") and abuse deterrent formulation technologies for use in orally administered opioid containing pharmaceutical products. The Company conducts research and development activities at its Culver, Indiana facility. The Culver facility is approved by the U.S. Drug Enforcement Administration ("DEA") for research, development and manufacturing Schedule II to V controlled substances in bulk and finished dosage forms. The Company, through its wholly-owned subsidiary, Houba, Inc., has made an application to the DEA for registration to import narcotic raw materials directly from foreign sources for use in the Company's API manufacturing process development and manufacturing activities at the Culver, Indiana facility. In the event the Company is successful in developing and scaling up for commercial production its API and finished dosage formulation technologies, the Company will enter into license and supply agreements with strategic partners providing that such partners will further develop orally administered products incorporating the Company's abuse deterrent formulation technologies, file for applicable regulatory approval and market and sell such products. It is the Company's intention to manufacture clinical trial supplies for use in obtaining regulatory approvals and commercial supplies of such products for marketing, sale and distribution by the Company's licensees. IVAX Pharmaceuticals New York LLC 77 Brenner Drive Congers, New York 10920 Telephone: (305) 575-6000 IVAX , a wholly-owned subsidiary of IVAX Corporation, was formed for the purpose of completing the purchase of the assets used in the operation of the Congers Facilities. IVAX Corporation is a multi-national company engaged in the research, development, manufacturing and marketing of branded and generic pharmaceuticals and veterinary products in the United States and internationally. IVAX Corporation has direct operations in 30 countries and markets its products in more than 80 countries around the world. REASONS FOR THE SALE OF THE CONGERS FACILITIES ASSETS (SEE PAGE 73) We are proposing to sell the Congers Assets to IVAX because we believe that the sale and the terms of the related Asset Purchase Agreement are in the best interests of our Company and our shareholders. The 4

Board of Directors has identified various benefits that are likely to result from the sale of the Congers Assets. The Board of Directors believes that the sale of the Congers Assets will: - Allow us to direct our resources to what the Board of Directors believes are the potentially better overall returns that may be derived from the development and commercialization of our proprietary opioid API synthesis and finished dosage formulation technologies while increasing our cash balance, reducing our cash burn and eliminating expenses primarily associated with the operation of the Congers Assets in the manufacture and sale of a variety of prescription and over-the-counter generic drugs; - Provide an improved organizational focus and free up senior management from directing the operation of multiple development, manufacturing and administrative locations; - Allow us to focus on a streamlined business strategy that the Board of Directors believes will provide competitive advantages potentially leading to greater returns for our shareholders; and - Allow us to increase our cash reserves by approximately $2.35 million (net of expenses) and thereby providing greater flexibility to develop and, if successful in development, commercialize opioid APIs and finished dosage pharmaceutical products incorporating our proprietary opioid synthesis and finished dosage formulation technologies. In reaching the conclusion that the sale of the Congers Assets to IVAX pursuant to the related Asset Purchase Agreement was in the best interests of our Company and our shareholders, the Board did, however, consider the potential adverse effects of other factors relating to the proposed asset sale, including: - The risk that, after the asset sale, the Company will have no ability to manufacture finished dosage generic products and that all of the Company's previous revenue generating products will have been sold; - The fact that the finished dosage manufacturing, packaging, labeling and distribution operations conducted at the Congers Facilities represented essentially all of the Company's product revenues for fiscal 2003 and 2002; - The risk that the Company will be able to develop and commercialize the Company's proprietary technologies; - The fact that in the absence of the Company's ability to successfully develop and commercialize the Company's proprietary technologies, the Company will have no ability to generate revenues from sales of generic products to partially offset operating expenses; and - The risk that the Company's cash resources to fund the development and commercialization of the Company's proprietary technologies and continuing operating losses may be insufficient to sustain the Company's cash needs until such time as revenues may be generated from such technologies. These and other reasons for approving and recommending the sale of our Congers Assets are discussed further under Proposal 4 of this Proxy Statement. PROCEEDS FROM THE SALE OF OUR CONGERS ASSETS (SEE PAGE 79) Our Company will retain the proceeds of the sale of our Congers Assets. We do not intend to distribute any of the proceeds to our shareholders, but will use the proceeds along with our cash and cash equivalents, in implementing our future business plans, including the development and commercialization of our proprietary opioid synthesis and finished dosage formulation technologies. TERMS OF ASSET PURCHASE AGREEMENT (SEE PAGE 89) WHAT WE WILL RECEIVE (SEE PAGE 90) IVAX will acquire all of the Congers Assets for the sum of $2.5 million and the assumption of certain contractual liabilities related to operation of such assets. We received $2.0 million of the purchase price at the 5

time of the signing of the Asset Purchase Agreement. The remaining $0.5 million will be paid at the closing of the asset sale following receipt of shareholder approval to sell the Congers Assets. We believe the source of the funds from which IVAX will pay the cash consideration for the Congers Assets will be from IVAX' working capital. WHAT IS BEING SOLD (SEE PAGE 89) We are selling to IVAX substantially all of the assets used in manufacturing, labeling, packaging, distributing and selling finished dosage generic pharmaceutical products located at our Congers, New York locations. These assets include the leases to both of our facilities in Congers, New York, consisting of our facility located on Brenner Drive (the "Brenner Drive Facility"), including our option to purchase the Brenner Drive Facility, and our lease agreement for our facility located on Wells Avenue (the "Wells Avenue Facility"), as well as all of our equipment, manufacturing information relating to such equipment, intellectual property, regulatory approvals, licenses, registrations and supporting documentation and records relating to certain generic products manufactured at the Brenner Drive Facility. WHEN WILL THE ASSET SALE BE COMPLETED (PAGE 90) The closing of the asset sale transaction will take place three business days following our receipt of shareholder approval of the proposal to sell the Congers Assets. In accordance with the terms of a use and license agreement between us and IVAX, IVAX is permitted to use the Congers Assets from the date of signing of the Asset Purchase Agreement until the closing of the asset sale following receipt of shareholder approval. ASSUMED LIABILITIES (PAGE 90) As partial consideration for the purchase of our Congers Assets, at the signing of the Asset Purchase Agreement, IVAX assumed our obligations under the lease agreement of the Wells Avenue Facility. The lease for the Wells Avenue Facility has an initial term expiring June 30, 2004 and provides for a monthly rental payment of $11,255. On March 19, 2004, we exercised the purchase option under the lease for the Brenner Drive Facility and assigned our rights under the contract of sale to IVAX. On the same day, simultaneous with the closing of the sale of the Brenner Drive Facility from Par Pharmaceutical, Inc. to IVAX, we terminated the lease for the Brenner Drive Facility. REPRESENTATIONS AN WARRANTIES (PAGE 91) The Asset Purchase Agreement contains customary representations and warranties included in similar transactions. The representations and warranties will survive the completion of the sale of the Congers Assets for a period of three years, excluding our representations and warranties relating to title to the Congers Assets, environmental conditions and taxes, which survive without limitation. TERMINATION (PAGE 93) The Asset Purchase Agreement may be terminated under certain circumstances, including the following: - Upon the mutual written consent of Halsey and IVAX; - By either Halsey or IVAX if a governmental authority takes action to enjoin or otherwise prohibit the transactions contemplated in the Asset Purchase Agreement; - By IVAX in the event the sale of the Congers Assets does not occur within 10 days following our receipt of shareholder approval of our sale of the Congers Asset; and - By either party upon notice on or after January 1, 2005 in the event that by January 1, 2005 we have not obtained shareholder approval to sell the Congers Assets and a meeting of our shareholders has been held during which our sale of the Congers Assets was considered by our shareholders for approval. 6

If the Asset Purchase Agreement is terminated for the reasons specified above, we must refund to IVAX the $2.0 million payment received by us at the signing of the Asset Purchase Agreement. The termination of the Asset Purchase Agreement shall not affect the assignment of the lease for the Wells Avenue Facility. CONDITIONS TO COMPLETION OF THE ASSET PURCHASE (PAGE 93) Each parties' obligation to complete the sale of the Congers Assets is subject to the prior satisfaction or waiver of certain conditions. In addition to customary closing conditions, we have to comply with the following material conditions that must be satisfied or waived before completion of the sale of the Congers Assets: - We will have obtained approval of our shareholders in accordance with the New York Business Corporation Law. - We will have filed with the U.S. Food and Drug Administration the information required to transfer to IVAX the regulatory approvals relating to the prescription generic pharmaceutical products manufactured at the Congers, New York locations and conveyed to IVAX pursuant to the Asset Purchase Agreement. - We will have delivered to IVAX evidence that all liens, security interests, mortgages or encumbrances on the Congers Assets have been terminated or removed. ADDITIONAL AGREEMENTS RELATED TO THE ASSET PURCHASE AGREEMENT (SEE PAGE 95) USE AND LICENSE AGREEMENT (PAGE 95) Concurrently with the execution of the Asset Purchase Agreement, Halsey and IVAX executed a use and license agreement providing for IVAX' use of the Congers Assets during the term of the Asset Purchase Agreement until the Congers Assets are conveyed to IVAX. VOTING AGREEMENT (PAGE 95) Concurrently with the execution of the Asset Purchase Agreement, certain of our major securityholders entered into a voting agreement with IVAX pursuant to which these securityholders have granted IVAX an irrevocable proxy to vote their voting securities at a meeting of the Company's shareholders or any adjournment therefore in favor of the proposed sale of the Congers Assets to IVAX. 7

VOTING OF PROXIES Proxies may be revoked by shareholders at any time prior to the voting thereof by giving notice of revocation in writing to the Secretary of the Company or by voting in person at the Meeting. If the enclosed proxy is properly signed, dated and returned, the Common Stock represented thereby will be voted at the Meeting and will be voted in accordance with the specifications made thereon. IF NO INSTRUCTIONS ARE INDICATED, THE COMMON STOCK REPRESENTED THEREBY WILL BE VOTED (i) FOR the election of Directors, (ii) FOR the restatement of the Company's Certificate of Incorporation (the "Charter") to increase the number of authorized shares of the Company's Common Stock from 80,000,000 shares to 650,000,000 shares and to authorize 290,000,000 shares of Preferred Stock, (iii) FOR the amendment to the Company's Charter to change the name of the Company to Acura Pharmaceuticals, Inc., (iv) FOR the approval of the sale of substantially all of the assets used in the operation of the Company's Congers, New York locations, (v) FOR the adoption of the amendment to the Company's 1998 Stock Option Plan, and (vi) FOR the ratification of the appointment of Grant Thornton LLP as the Company's independent certified public accountants for the fiscal year ending December 31, 2004. THE BOARD OF DIRECTORS During the year ended December 31, 2003, the Board of Directors held nine meetings. None of the Company's Board members attended less than 75% of the Board meetings held during 2003. It is the policy of the Board that Directors are strongly encouraged to attend all board meetings and shareholder meetings. BOARD COMMITTEES During 2003, the Company had an Audit Committee, a Compensation Committee, a Stock Option Committee, an Executive Committee and a Technology Committee of the Board of Directors. AUDIT COMMITTEE During 2003, the Audit Committee was composed of Messrs. William A. Sumner, Chairman, Immanuel Thangaraj, Alan Smith and Bruce F. Wesson. The Audit Committee is responsible for selecting the Company's independent auditors, approving the audit fee payable to the auditors, working with independent auditors, reviewing the scope and results of the audit by, and the recommendations of, the Company's independent auditors, approving the services provided by the auditors, reviewing the financial statements of the Company and reporting on the results of the audits to the Board, reviewing the Company's insurance coverage, financial controls and filings with the Securities and Exchange Commission (the "Commission"), including, meeting quarterly prior to the filing of the Company's quarterly and annual reports containing financial statements filed with the Commission, and submitting to the Board its recommendations relating to the Company's financial reporting, accounting practices and policies and financial, accounting and operational controls. The Audit Committee held three formal meetings and numerous informal meetings during 2003. A report of the Audit Committee is also contained under Proposal 6 in this Proxy Statement. The Charter of the Audit Committee is attached as Appendix A to this Proxy Statement. In assessing the independence of the Company's Audit Committee members during 2003, the Company has reviewed and analyzed the standards for independence provided in Section 121A of the American Stock Exchange Listing Standards. Based on this analysis, the Company has determined that each of Messrs. Sumner and Smith are deemed independent members of the Audit Committee. While Messrs. Wesson and Thangaraj do not satisfy the standards for independence set forth in the American Stock Exchange Listing Standards as a result of the controlling interest held by each of Galen Partners III, L.P., of which Mr. Wesson is a general partner, and Essex Woodlands Health Ventures, of which Mr. Thangaraj is a general partner, the Board values the experience of Messrs. Wesson and Thangaraj in the review of the Company's financial statements and believes that each is able to exercise independent judgment in the performance of his duties on the Audit Committee. 8

The Audit Committee does not have a financial expert (as defined under applicable regulations of the Commission) serving on the Committee. The Board has determined that while none of the Audit Committee members meet all of the criteria established by the Commission to be classified as a "financial expert", the Company believes that in general the members of the Audit Committee have a sufficient understanding of audit committee functions, internal control over financial reporting and financial statement evaluation so as to capably perform the tasks required of the Audit Committee. Commencing with the date of the Meeting, the Audit Committee will be composed of Messrs. Sumner, Wesson and Thangaraj. COMPENSATION COMMITTEE The Company's Compensation Committee, composed of Messrs. Bruce F. Wesson, Srini Conjeevaram, William Skelly and Immanuel Thangaraj during 2003, is responsible for consulting with and making recommendations to the Board of Directors about executive compensation arrangements and the compensation of employees. See "Compensation of Executive Officers and Directors -- Report of the Compensation Committee on Executive Compensation" below. The Compensation Committee met four times in 2003. Commencing with the date of the Meeting, the Compensation Committee will be comprised of Messrs. Karabelas, Skelly and Reddick. STOCK OPTION COMMITTEE The Stock Option Committee, composed of Messrs. William Skelly, Alan Smith and William A. Sumner during 2003, is responsible for reviewing Management's recommendations as to employee option grants and to grant options under the Company's stock option plans to employees, directors and consultants. The Stock Option Committee met once in 2003. Commencing with the date of the Meeting, the Stock Option Committee will be dissolved and the Board of Directors will thereafter perform the functions previously conducted by the Stock Option Committee. EXECUTIVE COMMITTEE The Executive Committee, composed of Messrs. Srini Conjeevaram, Joel D. Liffmann, Bruce F. Wesson, William Skelly, Peter A. Clemens, Jerry Karabelas and Immanuel Thangaraj during 2003, is responsible for acting on behalf of the Board of Directors in lieu of a full Board meeting on such matters that are not of the type required to be considered by the full Board of Directors and to advise the Board as to the issues and matters under review by the Executive Committee at the meetings of the Board of Directors. The Executive Committee met three times in 2003. In view of the reduced size of the Company's Board, effective as of the date of the Meeting the Executive Committee will be dissolved. TECHNOLOGY COMMITTEE The Technology Committee, composed of Messrs. Zubeen Shroff, Alan Smith and Jerry Karabelas during 2003, is responsible for addressing and reviewing regulatory oversight of the Company's operations, including compliance with applicable Drug Enforcement Administration and Food and Drug Administration regulations, compliance with state agency and regulatory requirements, compliance with Medicare reimbursement requirements and consulting with the Board regarding current and future compliance with applicable Federal and state regulations, including current Good Manufacturing Practice regulations. The Technology Committee met twice in 2003. In view of the reduced size of the Company's Board, effective as of the date of the Meeting the Technology Committee will be dissolved and the Board of Directors will thereafter perform the functions previously conducted by the Technology Committee. NOMINATING COMMITTEE The Company does not have a standing nominating committee. Currently the Board of Directors functions as the Company's nominating committee. The Board performs the functions typical of a nominating committee, including the identification, recruitment and selection of nominees for election as directors of the 9

Company. Two of the six members of the Board (Messrs. Sumner and Skelly) are "independent" as that term is defined by Section 121(A) of the American Stock Exchange Listing Standards and participate with entire Board in the consideration of director nominees. The nominees for election as directors at the Meeting were unanimously recommended by the Board. The Board believes that a nominating committee separate from itself is not necessary at this time, given the size of the Company and the Board, to ensure that candidates are appropriately evaluated and selected. The Board also believes that, given the Company's size and the size of its Board, an additional committee of the Board would not add to the effectiveness of the evaluation and nomination process. For these reasons, the Board believes it is not appropriate to have a nominating committee. Additionally, as described below under "Proposal 1 -- Agreements Governing Appointment of Directors", the Company is a party to a Voting Agreement dated as of February 6, 2004 which provides, among other things, that the Board of Directors shall be comprised of not more than seven (7) members, four (4) of whom shall be designees of the principal investors in the Company's 2004 Debentures, two (2) of whom shall be independent directors and one (1) of whom shall be the Company's Chief Executive Officer. In view of the contractual provisions contained in the Voting Agreement relating to the composition of the Board of Directors, the Board does not believe that the existence of a nominating committee of the Board would add to the effectiveness of the director evaluation and nomination process. The Board's process for recruiting and selecting nominees is for Board members to identify individuals who are thought to have the business background and experience, industry specific knowledge and general reputation and expertise that would allow them to contribute as effective directors to the Company's governance, and who are willing to serve as directors of a public company. To date, the Company has not engaged any third party to assist in identifying or evaluating potential nominees. After a possible candidate is identified, the individual meets with various members of the Board and is sounded out concerning their possible interest and willingness to serve, and Board members discuss amongst themselves the individual's potential to be an effective Board member. If the discussions and evaluation are positive, the individual is invited to serve on the Board. To date, no shareholder has presented any candidate for Board membership to the Company for consideration, and the Company does not have a specific policy on shareholder-recommended director candidates. However, the Board believes its process for evaluation of nominees proposed by shareholders would be no different from the process of evaluating any other candidate. In evaluating candidates, the Board will require that candidates possess, at a minimum, a desire to serve on the Company's Board, an ability to contribute to the effectiveness of the Board, an understanding of the function of the Board of a public company and relevant industry knowledge and experience. In addition, while not required of any one candidate, the Board would consider favorably experience, education, training or other expertise in business or financial matters and prior experience serving on boards of public companies. Messrs. Reicher and Liffmann resigned as Directors of the Company effective September 18, 2003 and November 13, 2003, respectively. SHAREHOLDER COMMUNICATIONS TO THE BOARD Shareholders who wish to send communications to the Company's Board of Directors may do so by sending them in care of the Secretary of the Company at the address which appears on cover page of this Proxy Statement. The envelope containing such communication must contain a clear notation indicating that the enclosed letter is a "Shareholder-Board Communication" or "Shareholder-Director Communication" or similar statement that clearly and unmistakably indicates the communication is intended for the Board. All such communications must clearly indicate the author as a shareholder and state whether the intended recipients are all members of the Board or just certain specified directors. The Secretary of the Company will have the discretion to screen and not forward to directors communications which the Secretary determines in his or her discretion are communications unrelated to the business or governance of the Company and its subsidiaries, commercial solicitations, or communications that are offensive, obscene, or otherwise inappropri- 10

ate. The Secretary will, however, compile all shareholder communications which are not forwarded and such communications will be available to any director. PROPOSAL 1 ELECTION OF DIRECTORS At the Meeting, six individuals will be elected to serve as Directors until the next annual meeting, and until their successors are elected and qualified. During the fiscal year ended December 31, 2003, each of nominees to the Board with the exception of Andrew Reddick, the Company's President and Chief Executive Officer, served as Directors. See "Agreements Governing Appointment of Directors" below. Unless a shareholder WITHHOLDS AUTHORITY, a properly signed and dated proxy will be voted FOR the election of the persons named below, unless the proxy contains contrary instructions. Management has no reason to believe that any of the nominees will not be a candidate or will be unable to serve as a Director. However, in the event any nominee is not a candidate or is unable or unwilling to serve as a Director at the time of the election, unless the shareholder withholds authority from voting, the proxies will be voted for any nominee who shall be designated by the present Board of Directors to fill such vacancy. Although the Company's Charter provides for a maximum of 11 directors, in accordance with the terms of a certain Voting Agreement dated February 6, 2004 by and among the Company and the holders of the Company's outstanding senior secured convertible debentures, the Company has agreed that the Board of Directors shall be comprised of not more than seven members.

STOCK OPTION PLANS The Company currently maintains two stock option plans adopted in 1995 and 1998, respectively. The Company in the past has used, and will continue to use, stock options to attract and retain key employees in the belief that employee stock ownership and stock-related compensation devices encourage a community of interest between employees and shareholders. The 1995 Stock Option Plan. In September, 1995, the Company established the 1995 Halsey Drug Co., Inc. Stock Option and Restricted Stock Purchase Plan (the "1995 Stock Option Plan"). Under the 1995 Stock Option Plan, the Company may grant options to purchase up to 1,000,000 shares of the Company's Common Stock. Incentive Stock Options ("ISO's") may be granted to employees of the Company and its subsidiaries and non-qualified options may be granted to employees, directors and other persons employed by, or performing services for, the Company and its subsidiaries. Subject to the 1995 Stock Option Plan, the Stock 17

Option Committee determines the persons to whom grants are made and the vesting, timing, amounts and other terms of such grants. An employee may not receive ISO's exercisable in any one calendar year for shares with a fair market value on the date of grant in excess of $100,000. No quantity limitations apply to the grant of non-qualified stock options. As of June 1, 2004, ISO's to purchase 630,608 shares and non-qualified options to purchase 257,780 shares have been granted under the 1995 Stock Option Plan, leaving 111,612 shares available for grant under the Plan. The average per share exercise price for all outstanding options under the 1995 Stock Option Plan is approximately $1.44. No exercise price of an ISO was set at less than 100% of the fair market value of the underlying Common Stock. For grants made to any person who owned stock possessing more than 10% of the total voting power of the Company the exercise price was set at not less than 110% of the fair market value of the underlying Common Stock. The 1998 Stock Option Plan. The 1998 Stock Option Plan was adopted by the Board of Directors in April, 1998 and approved by the Company's shareholders in June 1998. The 1998 Stock Option Plan was amended by the Board of Directors in April, 1999 to increase the number of shares available for the grant of options under the Plan from 2,600,000 to 3,600,000 shares. The Company's shareholders ratified the Plan amendment on August 19, 1999. The 1998 Stock Option Plan was further amended by Board of Directors in April, 2001 to increase the number of shares available for grant of options under the Plan from 3,600,000 to 8,100,000 shares. The Company's shareholders ratified the Plan amendment on June 14, 2001. In accordance with the description contained under the caption "Proposal 5 -- Amendment to the Company's 1998 Stock Option Plan" the Board is seeking authorization to amend the 1998 Stock Option Plan to (a) increase the number of shares available for grant of options under the Plan from 8,100,000 to 20,000,000 shares, (b) permit the grant of non-qualified stock options having an exercise price per share which is less than the fair market value of the Company's Common Stock, and (c) set a limit of 8,750,000 option awards that may be granted to one individual in any calendar year. The 1998 Stock Option Plan permits the grant of ISO's and non-qualified stock options to purchase shares of the Company's Common Stock. As of June 1, 2004, stock options to purchase 2,691,342 shares had been granted under the 1998 Stock Option Plan. Of such option grants, 1,562,466 are ISOs and 1,128,876 are non-qualified options. The average per share exercise price for all outstanding options under the 1998 Stock Option Plan is approximately $1.94. For a description of the 1998 Stock Option Plan as well as the proposed amendment thereto, see "Proposal 5 -- Amendment to the Company's 1998 Stock Option Plan" contained in this Proxy Statement.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Company's Compensation Committee consisted of Messrs. Wesson, Conjeevaram, Skelly, Reicher and Thangaraj during fiscal 2003. During 2003, except for Mr. Reicher, there were no Compensation Committee interlocks or insider participation in compensation decisions. Mr. Reicher resigned as a Director of the Company effective September 18, 2003. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company's Directors and executive officers, and persons who own beneficially more than ten percent (10%) of the Common Stock of the Company, to file reports of ownership and changes of ownership with the Commission and, during the 19

period in which the Company's common stock was traded on the American Stock Exchange, the AMEX. Copies of all filed reports are required to be furnished to the Company pursuant to Section 16(a). Based solely on the reports received by the Company and on written representations from reporting persons, the Company believes that the Directors, executive officers and greater than ten percent (10%) beneficial owners of the Company's Common Stock complied with all Section 16(a) filing requirements during the year ended December 31, 2003, except that (i) Mr. Reicher filed two Form 4 filings late, (ii) Mr. Thangaraj filed three Form 4 filings late, (iii) Mr. Feinberg filed two Form 4 filings late, and (iv) a Form 3 filing requirement by Mr. Dennis Adams, a beneficial owner of in excess of 10% of the Company's Common Stock, has not been filed to date. The following report of the Compensation Committee and the performance graph in the next section shall not be deemed to be "soliciting material" or to be "filed" with the Commission or subject to regulations 14A or 14C of the Commission or to the liabilities of Section 18 of the Exchange Act and shall not be deemed to be incorporated by reference into any filing under the Securities Act of 1933 or the Exchange Act, notwithstanding any general incorporation by reference of this Proxy Statement into any other document. REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION This report has been prepared by the Compensation Committee of the Board of Directors of the Company (the "Compensation Committee"). The Compensation Committee was formed in February, 1993. Messrs. Wesson, Conjeevaram, Skelly, Reicher and Thangaraj served as members of the Compensation Committee during 2003. Mr. Reicher resigned as a director of the Company effective September 18, 2003. The Committee meets at least annually or more frequently, as the Company's Board of Directors may request. The Compensation Committee's primary responsibilities include the review of compensation, consisting of salary, bonuses, benefits, and other annual compensation, of the Company's executive officers. EXECUTIVE COMPENSATION PHILOSOPHY In 2004, the Company's executive compensation program will reflect the following executive compensation philosophy, which was developed by the Compensation Committee of the Board of Directors: The Company's mission is to develop and, in concert with our prospective partners, commercialize opioid abuse deterrent formulation technology and opioid active pharmaceutical ingredient synthesis technologies with an objective of providing cost effective solutions intended to deter abuse of legally prescribed opioids in the US and other key territories around the world. To support this and other strategic objectives as approved by the Board of Directors and to provide adequate returns to shareholders, the Company must compete for, attract, develop, motivate and retain top quality executive and scientific talent during periods of both favorable and unfavorable business conditions. The Company's executive compensation program is a critical management tool in achieving this goal. "Pay for performance" is the underlying philosophy for the Company's executive compensation program. Consistent with this philosophy, the program has been carefully conceived and will be independently administered by the Compensation Committee of the Board of Directors, a majority of whom are independent non-employee directors. The program is designed to link executive pay to corporate performance, including share price, recognizing that there is not always a direct and short-term correlation between performance and share price. To align shareholder interests and executive rewards, portions of each of the Company's executive's compensation will represent "at risk" pay opportunities related to accomplishment of specific business goals. The program is designed and administered to: - provide annual and longer term incentives that help focus each executive's attention on approved corporate business goals the attainment of which, in the judgment of the Compensation Committee, should increase long-term shareholder value; 20

- link "at risk" pay with appropriate measurable quantitative and qualitative achievements against approved performance parameters; - reward individual and team achievements that contribute to the attainment of the Company's business goals; and - provide a balance of total compensation opportunities, including salary, bonus, and longer term equity incentives, that are competitive with similarly situated companies and reflective of the Company's performance. In seeking to link executive pay to corporate performance, the Compensation Committee believes that the most appropriate measure of corporate performance is the increase in long-term shareholder value, which involves improving such quantitative performance measures as revenue, net income, cash flow, operating margins, earnings per share and return on shareholders' equity. The Compensation Committee may also consider qualitative corporate and individual factors which it believes bear on increasing the long-term value of the Company to its shareholders. These include (i) the development of competitive advantages, (ii) the ability to deal effectively with the complexity of the Company's businesses, (iii) success in developing business strategies, managing costs and improving the quality of the Company's technologies, (iv) the general performance of individual job responsibilities, and (v) the successful development and patent protection for opioid synthesis and abuse deterrent formulation technologies useful in finished dosage pharmaceutical products. COMPONENTS OF EXECUTIVE COMPENSATION PROGRAM The Company's executive compensation program consists of (i) an annual salary and bonus and (ii) long-term incentives represented by the issuance of stock options. As explained below, the bonuses and stock options serve to link executive pay to corporate performance, since the attainment of these awards depends upon meeting the quantitative and, if applicable, qualitative performance goals which serve to increase long-term shareholder value. Salary and Bonus. The Company's Chief Executive Officer, Chief Scientific Officer, Chief Operations Officer and Chief Financial Officer are parties to employment contracts with the Company which provide the minimum annual base salary to be payable to such officers. In addition, the employment contracts provide for an annual bonus, in the discretion of the Compensation Committee, subject to the satisfaction of such targets, conditions or parameters as may be set from time to time by the Compensation Committee. For those executive officers not subject to an employment contract, the Compensation Committee will set the annual salary for such executive officers in or about March of each year and establish potential bonus compensation (including Messrs. Reddick, Spivey, Kumar and Clemens) that such executives may earn based upon quantitative and, if applicable, qualitative performance goals established by the Compensation Committee. The goals for 2004 will consist of a mix of targets and performance measures of corporate revenue, development milestones relating to the Company's opiate synthesis and finished dosage formulation technologies and qualitative goals relating to each officer's job function. No bonus will be earned with respect to a performance measure unless a performance "floor" for that measure is exceeded; the bonus opportunity with respect to a measure will be earned if the target is achieved; achievement between the floor and the target results in a lower bonus with respect to that performance measure. An amount larger than the bonus opportunity for each performance measure can be earned, up to a specified limit, for exceeding the target for that measure. In setting compensation levels, the Compensation Committee compares the Company to companies of comparable business focus, market capitalization, technological capabilities and market in which the Company competes for executives. In ascertaining the achieved level of performance against the targets, the effects of certain extraordinary events, as determined by the Compensation Committee, such as (i) major acquisitions and divestitures, (ii) significant one-time charges, and (iii) changes in accounting principles required by the Financial Accounting Standards Board, are "compensation neutral" for the year in which they occurred; that is, they are not taken into account in determining the degree to which the targets are met in that year. 21

Stock Options. The long-term component of the Company's executive compensation program consists of stock option grants. The options generally permit the option holder to buy the number of shares of Common Stock covered by the option (an "option exercise") at a price fixed at the time of grant. While the Company historically has granted stock options having an exercise price equal to the fair market value of the Company's Common Stock on the date of grant, during 2003 and 2004, the Company made commitments to issue stock options to its employees at a discount to the market price. The grant of such options is subject to the receipt of shareholder approval to the amendments to the Company's 1998 Stock Option Plan (see "Proposal 5 -- Amendment to the Company's 1998 Stock Option Plan"). It is the expectation of the Compensation Committee that discounted stock option grants will occur on only an isolated basis in the future where circumstances warrant. With respect to stock options grants having an exercise price equal to or greater than the market price of the Company's Common Stock on the date of grant, such options generally gain value only to the extent the stock price exceeds the option exercise price during the life of the option. Generally, a portion of the options vest over a period of time and expire no later than ten years, and in some cases five years after grant. Executives will generally be subject to limitations in selling the option stock immediately, and therefore will be incentivized to increase shareholder value. During fiscal 2003, the Company's Chief Executive Officer, Chief Operations Officer and Chief Financial Officer were parties to employment contracts which provided for a certain minimum annual base salary. Total bonuses paid during 2003 to executive officers aggregated $170,000. In conclusion, the Compensation Committee believes the compensation policies and practices of the Company, as described, are fair and reasonable and are in keeping with the best interests of the Company, its employees and its shareholders.

PERFORMANCE GRAPH The following graph provides a comparison on a cumulative basis of the yearly percentage change over the last five fiscal years in (a) the total shareholder return on the Company's Common Stock with (b) the total return on the American Stock Exchange ("AMEX") of all domestic issuers traded on the AMEX and (c) the total return of domestic issuers having the same Standard Industrial Classification ("SIC") Industry Group Number as the Company (283-Drug Manufacturers) (the "Industry Index"). Such yearly percentage change has been measured by dividing (i) the sum of (A) the amount of dividends for the measurement period, assuming dividend reinvestment, and (B) the difference between the price per share at the end and at the beginning of the measurement period, by (ii) the price per share at the beginning of the measurement period. The AMEX Index has been selected as the required broad equity market index. The Industry Index consists of publicly traded companies in a business similar to that of the Company. The price of each investment unit has been set at $100 on December 31, 1998 for purposes of preparing this graph.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS On December 20, 2002, the Company completed a private offering of securities for an approximate aggregate purchase price of $26,394,000 (the "2002 Debenture Offering"). The securities issued in the 2002 Debenture Offering consisted of 5% convertible senior secured debentures maturing March 31, 2006 (the "2002 Debentures"). The Debentures were issued by the Company pursuant to a certain Debenture Purchase 23

Agreement dated December 20, 2002 (the "2002 Purchase Agreement") by and among the Company, Care Capital, Essex, Galen and each of the purchasers listed on the signature page thereto. The Company believes the terms of the 2002 Purchase Agreement were at least as favorable to the Company as could have been obtained from unrelated third parties. In accordance with the terms of the 2002 Purchase Agreement, each of Jerry Karabelas, a designee of Care Capital, and Immanuel Thangaraj, a designee of Essex, were appointed to the Company's Board of Directors. As part of the closing of the 2002 Debenture Offering, the Company's term loan agreement (the "Watson Loan Agreement") with Watson Pharmaceuticals, Inc. ("Watson") was amended to (i) extend the maturity date of the Watson Loan Agreement from March 31, 2003 to March 31, 2006, and (ii) increase the principal amount of the Watson Loan Agreement from $17,500,000 to $21,401,331 (the "Watson Term Loan") to reflect the inclusion of approximately $3,901,331 owed by the Company to Watson under a product supply agreement between the parties. The Company believes the terms of the Watson Loan Agreement, as amended, were at least as favorable to the Company as could have been obtained from unrelated third parties. In consideration for the amendment to the Watson Loan Agreement, the Company issued to Watson a Common Stock purchase warrant exercisable for 10,700,665 shares of the Company's Common Stock (the "Watson Warrant"). The Watson Warrant has a term expiring December 31, 2009 and an exercise price of $0.34 per share. At the Company's request, on May 5, 2003, the Company received a letter executed by each of Care Capital, Galen and Essex (the "Majority 2002 Debentureholders") advising that the Majority 2002 Debentureholders would provide funding to meet the Company's 2003 capital requirements, up to an aggregate amount not to exceed $8.6 million (the "2003 Letter of Support"). In consideration for the issuance of the 2003 Letter of Support, the Company authorized the issuance of warrants to the Majority 2002 Debentureholders exercisable for an aggregate of 645,000 shares of the Company's Common Stock at an exercise price of $0.34 per share (such exercise price being equal to the conversion price of the 2002 Debentures). In accordance with the terms of the Letter of Support, the Majority 2002 Debentureholders advance to the Company an aggregate principal amount of $8.6 million during the period from June 16, 2004 through and including December 31, 2003 to fund the Company's operating losses and working capital requirements (the "Letter of Support Advances"). The Letter of Support Advances were made in accordance with the terms of the 2002 Purchase Agreement resulting in the Company's issuance of additional 2002 Debentures in an aggregate principal amount of $8.6 million (plus additional 2002 Debentures issued in satisfaction of accrued interest on the Letter of Support Advances). The Company believes the terms of the 2003 Letter of Support and the Letter of Support Advances were at least as favorable to the Company as could have been obtained from unrelated third parties. On February 10, 2004, the Company consummated a private offering of convertible senior secured debentures (the "2004 Debentures") in the aggregate principal amount of approximately $12.3 million (the "2004 Debenture Offering"). The 2004 Debentures were issued by the Company pursuant to a certain Debenture and Share Purchase Agreement dated as of February 6, 2004, as amended June 6, 2004 (the "2004 Purchase Agreement") by and among the Company, Care Capital, Essex, Galen and each of the purchasers listed on the signature page thereto. The Company believes the terms of the 2004 Purchase Agreement and the 2004 Debentures were at least as favorable to the Company as could have been obtained from unrelated third parties. Of the approximate $12.3 million in debentures issued on February 10, 2004 under in the 2004 Debenture Offering, approximately $2.0 million of 2004 Debentures were issued in exchange for the surrender of a like amount of principal plus accrued and unpaid interest under the Company's 2002 Debentures issued to Care Capital, Essex and Galen during November and December, 2003 pursuant to the Letter of Support. On April 14, 2004 and May 28, 2004, the Company completed an additional closing under the 2004 Purchase Agreement pursuant to which the Company issued additional 2004 Debentures in the aggregate principal amount of $579,000 and $1.121 million, respectively, bringing the aggregate principal amount of 2004 Debentures issued by the Company under the 2004 Purchase Agreement to $14.0 million. After giving effect to the amendment to the 2004 Purchase Agreement dated June 6, 2004, to, among other things, increase the principal amount of the 2004 Debentures issuable under the 2004 Purchase Agreement from $14.0 million to 24

$17.5 million, as of June 6, 2004 there remained $3.5 million in principal amount of 2004 Debentures available for issuance under the 2004 Purchase Agreement. The 2004 Debentures (including the principal amount plus interest accrued at the date of conversion) will convert automatically into the Company's series A convertible preferred stock (the "Series A Preferred") immediately following the Company's receipt of shareholder approval of the Company's restated Certificate of Incorporation (the "Charter Amendment") as described in Proposal 2 of this Proxy Statement, and the filing of the Charter Amendment with the Office of New York Department of State (the date of such filing, the "Charter Amendment Filing Date"). The Debentures will convert into Series A Preferred at a price per share (the "Conversion Price") of $0.6425, representing the average of the closing bid and asked prices of the Company's Common Stock for the 20 trading days ending February 4, 2004, as reported by the Over-the-Counter ("OTC") Bulletin Board. The closing bid price for the Company's Common Stock on January 20, 2004, the date of Board approval of the 2004 Debenture Offering, was $0.64 per share. Based on the $0.6425 Conversion Price of the Series A Preferred and estimating the interest accrual under the 2004 Debentures prior to the Charter Amendment Filing Date, the 2004 Debentures issued as of June 1, 2004 in the aggregate principal amount of $14.0 million are convertible into an aggregate of approximately 21.9 million Series A Preferred shares, of which 5.2 million, 6.8 million and 6.8 million are issuable to Care Capital, Essex and Galen, respectively, under the 2004 Debentures held by such parties (representing 23.8%, 30.9% and 30.9%, respectively, of the total Series A Preferred issuable upon conversion of the 2004 Debentures). The 2004 Purchase Agreement also provides that the holders of the Series A Shares shall have the right to vote as part of the single class with all holders of the Company's voting securities on all matters to be voted on by such security holders. Each holder of Series A Preferred shall have such number of votes as shall equal the number of votes he would have had if such holder converted all Series A Preferred held by such holder into shares of Common Stock immediately prior to the record date relating to such vote. Reference is made to Proposal 2 under the caption "Terms of Preferred Stock" for a more detailed description of the Series A Preferred. As a condition to the completion of the 2004 Purchase Agreement, the Company, the investors in the 2004 Debentures and the holders of the Company's outstanding 5% convertible senior secured debentures due March 31, 2006 issued by the Company in 1998, 1999, 2002 and 2003 (collectively, the "1998-2002 Debentures"), executed a certain Voting Agreement dated as of February 6, 2004 (the "Voting Agreement"). The Voting Agreement provides that each of Care Capital, Essex and Galen (collectively, the "Lead 2004 Investors") has the right to designate for nomination one member of the Company's Board of Directors, and that the Lead 2004 Investors collectively may designate one additional member of the Board (collectively, the "Designees"). The Designees of Care Capital, Essex and Galen are Messrs. Karabelas, Thangaraj and Wesson, respectively, each of whom are current Board members. The collective Designee of the Lead 2004 Investors has not yet been identified and designated. The Company believes the terms of the Voting Agreement were at least as favorable to the Company as could have been obtained from unrelated third parties. Simultaneous with the execution of a 2004 Purchase Agreement, and as a condition to the initial closing of the 2004 Purchase Agreement, the Company, the investors in the 2004 Debentures and each of the holders of the 1998-2002 Debentures (the 2004 Debentures and the 1998-2002 Debentures are collectively referred to as the "Outstanding Debentures") executed a certain Debenture Conversion Agreement dated as of February 6, 2004 (the "Conversion Agreement"). In accordance with the terms of the Conversion Agreement, each holder of the Outstanding Debentures agreed to convert their debentures into the Company's Preferred Stock. Specifically, the Conversion Agreement provides, among other things, for the automatic conversion of the 2004 Debentures into the Company's Series A Preferred and the automatic conversion of the 1998-2002 Debentures into the Company's Series B convertible preferred stock (the "Series B Preferred") and/or the Company's series C convertible preferred stock (the "Series C Preferred") immediately upon the Charter Amendment Filing Date. The Series B Preferred and the Series C Preferred are referred to collectively as the "Junior Preferred Shares", and the Junior Preferred Shares, together with the Series A Preferred are referred to collectively as the "Preferred Stock". Reference is made to Proposal 2 of this Proxy Statement for a more detailed description of the Conversion Agreement. The Company believes the terms of 25

the Conversion Agreement were at least as favorable to the Company as could have been obtained from unrelated third parties. After giving effect to the 2004 Debenture Offering and assuming (i) the receipt of shareholder approval of the Charter Amendment as provided in Proposal 2 of this Proxy Statement, (ii) the filing of the Charter Amendment, (iii) the conversion of the 2004 Debentures in the aggregate principal amount of $14.0 million outstanding as of June 1, 2004 into Series A Preferred, and (iv) the conversion of the 1998-2002 Debentures into Junior Preferred Shares, Care Capital, Essex and Galen would control approximately 14.7%, 17.1% and 45.5%, respectively, of the Company's voting securities (or approximately 13.3%, 15.5% and 46.9%, respectively, after giving effect to the conversion of all of the Company's issued and outstanding Common Stock purchase options and warrants). It was a condition to the completion of the 2004 Debenture Offering that the Watson Loan Agreement be restructured to provide for a reduction in the principal amount of the Watson Term Loan and for the assignment of the Watson Term Loan as restructured to Care Capital, Essex, Galen and the other investors in the 2004 Debentures as of February 10, 2004 (collectively, the "Watson Note Purchasers"). Accordingly, simultaneous with the closing of the 2004 Purchase Agreement, each of the Company, Watson and the Watson Note Purchasers executed an Umbrella Agreement dated as of February 6, 2004 (the "Umbrella Agreement"). The Umbrella Agreement provides for (i) the Company's payment to Watson of approximately $4.3 million and certain Company assets in consideration of amendments to the Watson term notes in the aggregate principal amount of approximately $21.4 million evidencing the Watson Term Loan (the "Watson Notes") (A) to forgive approximately $16.4 million of indebtedness under that Watson Notes, leaving a $5.0 million principal balance, (B) to extend the maturity date of the Watson Notes from March 31, 2006 to June 30, 2007, (C) to provide for the satisfaction of future interest payments under the Watson Notes in the form of the Company's Common Stock, and (D) to provide for the forbearance from the exercise of rights and remedies upon the occurrence of certain events of default under the Watson Notes (the Watson Notes as so amended, the "Amended and Restated Watson Note"), and (ii) Watson's sale and conveyance of the Amended and Restated Watson Note to the Watson Note Purchasers for cash consideration of $1.0 million. The Company believes the terms of the Umbrella Agreement were at least as favorable to the Company as could have been obtained from unrelated third parties. In accordance with the terms of the Umbrella Agreement, simultaneous with the Company's payment to Watson of approximately $4.3 million, the Company conveyed to Watson approximately $165,000 in finished dosage product, free of charge, as well as the Company's Abbreviated New Drug Application ("ANDA") for its butalbital, acetaminophen and caffeine tablet finished dosage product, the ANDA for its doxycycline hyclate capsule finished dosage product, and the drug master files and certain related assets for the Company's doxycycline monohydrate active pharmaceutical ingredient ("API") and doxycycline hyclate API, the Company's equipment dedicated to the production of doxycycline hyclate API and doxycycline monohydrate API (collectively, the "Transferred Assets"). The Company also granted to Watson an option to obtain a preferred source of supply of the hydrocodone bitartrate API (the "Hydrocodone Option"). In addition to Watson forgiveness of approximately $16.4 million of indebtedness under the Watson Notes, as additional consideration for the payment to Watson of approximately $4.3 million, the conveyance of the Transferred Assets, and the grant of the Hydrocodone Option, all current supply agreements between the Company and Watson were cancelled and Watson waived the dilution protections contained in the Watson Warrant, to the extent such dilution protections were triggered by the transactions contemplated in the 2004 Debenture Offering. The Amended and Restated Watson Note in the principal amount of $5.0 million is secured by a first lien on all of the Company's and its subsidiaries' assets, senior in right of payment and lien priority over all other Company indebtedness, carries a floating rate of interest equal to the prime rate plus 4.5% and matures on June 30, 2007. After giving effect to the transactions provided in the Umbrella Agreement, the Watson Note Purchasers represent the Company's senior lenders. The allocation of ownership of the $5.0 million Amended and Restated Watson Note among each of the Watson Note Purchasers was based on the quotient of the principal 26

amount of the 2004 Debentures purchased by such Watson Note Purchaser, divided by approximately $12.3 million, representing the aggregate principal amount of the 2004 Debentures issued by the Company on February 10, 2004. As such, of the $5.0 million principal amount of the Amended and Restated Watson Note, approximately $1,352,000, $1,754,000, and $1,754,000, is owed by the Company to Care Capital, Essex and Galen, respectively (representing approximately 27%, 35% and 35%, respectively, of the Amended and Restated Watson Note). Each of Michael and Susan Weisbrot and Dennis Adams beneficially own in excess of 5% of the Company's voting securities. Each of such security holders participated as an investor in the 2004 Debentures, agreed to convert their 1998-2002 Debentures into Junior Preferred Shares and purchased a portion of the Amended and Restated Watson Note a member of the Watson Note Purchasers. In addition, Bernard Selz, Hemant and Varsha Shah and Oracle Strategic Partners, L.P., each a beneficial owner of in excess of 5% of the Company's voting securities, is a party to the Conversion Agreement pursuant to which each has agreed to automatically convert their respective 1998-2002 Debentures into Junior Preferred Shares on the Charter Amendment Filing Date. See "Security Ownership of Certain Beneficial Owners and Management". VOTE REQUIRED Directors are elected by a plurality of the votes cast. The six candidates receiving the highest number of votes will be elected as directors. In accordance with the terms of 2004 Purchase Agreement, the Company and the holders of the Outstanding Debentures executed a certain Voting Agreement dated as of February 6, 2004. The Voting Agreement provides, among other things, that the parties will vote all of their respective voting securities of the Company in favor of one designee to the Board of Directors of each of Care Capital, Essex and Galen, as well as one collective designee to the Board specified by Care Capital, Essex and Galen. The Company has agreed to nominate and appoint to the Board of Directors, subject to shareholder approval, one designee of each of Care Capital, Essex and Galen, and one collective designee of Care Capital, Essex and Galen, for so long as each holds a minimum of 50% of the Series A Preferred shares initially issued to such party upon conversion of the 2004 Debentures (or at least 50% of the shares of the Company's Common Stock issuable upon conversion of the Series A Preferred). Messrs. Karabelas, Thangaraj and Wesson are the designees of each of Care Capital, Essex and Galen, respectively. The collective designee of each of Care Capital, Essex and Galen has not yet been identified and designated. The voting securities held by the parties to the Voting Agreement represent an aggregate of approximately 78.6% percent of the aggregate voting rights under the Company's outstanding voting securities. The Board of Directors recommends that the shareholders vote FOR each of the above nominees for Director. PROPOSAL 2 AUTHORIZATION TO AMEND AND RESTATE THE COMPANY'S CERTIFICATE OF INCORPORATION TO (I) INCREASE THE NUMBER OF AUTHORIZED SHARES OF ITS COMMON STOCK, $.01 PAR VALUE PER SHARE, FROM 80.0 MILLION SHARES TO 650.0 MILLION SHARES, AND (II) AUTHORIZE 290.0 MILLION SHARES OF CONVERTIBLE PREFERRED STOCK, $.01 PAR VALUE PER SHARE, OF WHICH 45.0 MILLION SHARES SHALL BE DESIGNATED SERIES A CONVERTIBLE PREFERRED STOCK, 25.0 MILLION SHARES SHALL BE DESIGNATED SERIES B CONVERTIBLE PREFERRED STOCK, 70.0 MILLION SHARES SHALL BE DESIGNATED SERIES C-1 CONVERTIBLE PREFERRED STOCK, 50.0 MILLION SHARES SHALL BE DESIGNATED SERIES C-2 CONVERTIBLE PREFERRED STOCK, AND 100.0 MILLION SHARES SHALL BE DESIGNATED SERIES C-3 CONVERTIBLE PREFERRED STOCK. 27

GENERAL At the Meeting, the Company's Shareholders will be asked to consider and approve the Company's Restated Certificate of Incorporation (the "Charter") to (i) to increase the number of authorized shares of the Company's Common Stock, $.01 par value per share, from 80,000,000 shares to 650,000,000 shares in order to provide sufficient authorized shares of Common Stock for issuance upon conversion of the Company's proposed classes of Preferred Stock (as hereinafter defined), and the exercise of the Company's outstanding Common Stock purchase options and warrants, and (ii) provide for additional capital stock consisting of 290,000,000 shares of convertible preferred stock, par value $.01 per share, of which 45,000,000 shares shall be series A convertible preferred stock (the "Series A Preferred"), 25,000,000 shares shall be designated series B convertible preferred stock (the "Series B Preferred"), 70,000,000 will be designated series C-1 convertible preferred stock (the "Series C-1 Preferred"), 50,000,000 will be designated series C-2 convertible preferred stock (the "Series C-2 Preferred"), and 100,000,000 shall be designated series C-3 convertible preferred stock (the "Series C-3 Preferred") The Series C-1 Preferred, Series C-2 Preferred and Series C-3 Preferred are referred to collectively as the "Series C Preferred. The Series B Preferred and the Series C Preferred are referred to collectively as the "Junior Preferred." The Series A Preferred, Series B Preferred and Series C Preferred are referred to collectively as the "Preferred Stock". The description of the liquidation preference, voting rights, conversion rights and other material terms of the Preferred Stock is set forth below under the caption "Terms of Preferred Stock". The amendment to the Charter to authorize the Preferred Stock is to allow for the conversion of all of the Company's outstanding convertible senior secured debentures (collectively, the "Outstanding Debentures") into Preferred Stock. Following such conversion, the Company will have no convertible debentures outstanding. As such, the amendment to the Charter also provides for the elimination of voting rights provided to the holders of the Company's convertible debentures issued in 1998 and 1999, each of which currently possess "as converted" voting rights. (See "Description of Charter Amendment" below). As of June 1, 2004, the principal and accrued and unpaid interest on the Outstanding Debentures aggregated $107.5 million. Unless this Proposal 2 is approved, the Company will not have the ability to convert the Outstanding Debentures into shares of Preferred Stock. BACKGROUND For the year ended December 31, 2003 the Company incurred a loss from operations of $17.2 million. During 2003, revenues from the sale of the Company's products to its primary customer, Watson Pharmaceuticals, had diminished significantly and the Company was unable to replace these revenues from other customers. Consequently, the Company failed to generate positive cash flow from operations and this prevented the Company from securing additional working capital from traditional banking sources. In view of the Company's continuing losses from operations and diminishing sources of working capital, during 2002 and 2003 the Company's Management engaged in extensive capital raising efforts. During the period from August 2001 through and including December 2002, Galen Partners III L.P. and its affiliates (collectively "Galen") advanced an aggregate of approximately $15.9 million in bridge loans to the Company to fund ongoing operations. The Galen bridge loans were evidenced by 10% convertible promissory notes and were secured by a lien on all of the Company's assets. In July 2002, the Board of Directors retained MTS Partners and CIBC as the Company's financial advisors to assist the Company in analyzing, planning, negotiating and executing the Company's strategic and financial plan, including the identification of a strategic partner or source of financing, or alternatively, an acquirer of the Company's business. Through the efforts of Senior Management and the Company's financial advisors, the Company solicited approximately 36 entities in an effort to form a strategic partnership, secure financing or negotiate a sale of the Company. As part of the discussions with such third parties, Management presentations were made and a descriptive memorandum describing the Company's operations was provided. While there was initial interest by a number of prospects, with the exception of Care Capital Investments II, LP and Essex Woodlands Health Ventures V, L.P. (as described in the paragraph below), all of such prospects indicated an unwillingness to entertain even preliminary discussions or negotiations with the Company relating to a financing, strategic partnership or acquisition transaction. Reasons provided by such parties included, but were not limited to, the absence of a strategic fit and the dilutive impact the acquisition of the Company would have on the acquirer's earnings. 28

On December 20, 2002, the Company completed a private offering of securities for an aggregate purchase of approximately $26.4 million (the "2002 Offering"). Securities issues in the 2002 Offering consisted of 5% convertible senior secured debentures (the "2002 Debentures"). The 2002 Debentures were issued by the Company pursuant to a certain Debenture Purchase Agreement dated December 20, 2002 (the "2002 Purchase Agreement") by and among the Company, Care Capital Investments II LP, Essex Woodlands Health Ventures V, L.P., Galen and other purchasers listed on the signature page thereto. Of the approximate $26.4 million in 2002 Debentures issued in the 2002 Offering, approximately $15.9 million of 2002 Debentures were issued in exchange for the surrender of a like amount of principal and accrued interest under the Company's 10% convertible promissory notes issued to Galen and certain other lenders pursuant to bridge financing made during the period from August 2001 through December 2002. The proceeds of the 2002 Offering were used by the Company for working capital and to fund continuing operating losses. Subsequent to the completion of the 2002 Offering, Senior Management continued its efforts to identify third- party financing, a strategic partner or a potential acquirer of the Company's business. Additionally, Senior Management implemented changes designed to contain costs and increase product sales. In March 2003, the Company notified Watson Pharmaceuticals ("Watson") that the Company intended to commence the direct marketing and sale of the Company's core products in addition to sales of such products to Watson, as provided for under the Core Products Supply Agreement with Watson. The Company commenced the direct sales of its products in the summer of 2003. In view of the limited number of the Company's products and the intense market competition for these products, the Company's direct sales of its core products did not result in significant revenue enhancement. This combined with steadily declining purchases by Watson under the Core Products Supply Agreement resulted in increasing operating losses and a shortfall of cash to fund operations. In order to provide interim financing to fund operations during the period of Management's capital raising efforts, at the Company's request, each of Care Capital Investments II, LP ("Care Capital"), Essex Woodlands Health Ventures V, L.P. ("Essex") and Galen issued a letter of support dated May 5, 2003 (the "Letter of Support"). The Letter of Support provided that Care Capital, Essex and Galen would provide funds to meet the Company's 2003 capital requirements, up to an amount not to exceed $8.6 million, on terms to be negotiated by the parties. During the period from June 16, 2003 through October 7, 2003, an aggregate of $6.6 million was advanced to the Company by Care Capital, Essex and Galen under the Letter of Support, under the same terms as the Company's 5% convertible senior secured debentures issued in 2002 (as described below). Despite Management's efforts to obtain other sources of financing during this period, the Company was unable to identify any third party willing to entertain even preliminary discussions to provide financing to the Company. As of October 31, 2003, the Company had cash and cash equivalents of approximately $1,070,000 as compared to approximately $9,211,000 at December 31, 2002. Additionally, the Company was in default under its $21.4 million senior term loan agreement with Watson as well as its then outstanding debentures. As of November 1, 2003, $2.0 million remained available for advance to the Company under the Letter of Support with no assurances from the Majority 2002 Debentureholders that such amount would actually be transferred to the Company pursuant to the terms of the Letter of Support. The Company projected that if advanced, such amount would likely fund operations only through January 2004. NEGOTIATIONS BETWEEN THE COMPANY AND THE LEAD 2004 INVESTORS In view of the Company's current financial condition and limited cash resources, the early stage of the Company's proprietary technologies, the efforts of Management and each of MTS Partners and CIBC, the Company's financial advisors, to identify and obtain additional sources of financing and/or provide for a sale of the Company, all of which efforts were unsuccessful, at its meeting held on October 30, 2003, the Board of Directors determined that the Company's current securityholders could be the sole source of financing to fund the Company's ongoing operations. As a result, during the October 30, 2003 Board meeting, the Board formally requested that each of Care Capital, Galen Partners, Essex Woodlands and Oracle Strategic Partners, each of which had a designee on the Board of Directors, respond to the Board as expeditiously as possible as to whether additional financing would be provided to the Company by such entities and, if so, the 29

proposed terms of such financing. The representatives of each of Galen Partners, Care Capital, Essex Woodlands and Oracle Strategic Partners in attendance at the Board meeting advised that they would commence internal discussions as to the provision of additional financing to the Company and would endeavor to provide the Board with their response as soon as possible. During the October 30, 2003 Board meeting, the Board of Directors also authorized the creation of the Independent Committee of the Board of Directors, consisting of Messrs. Sumner, Skelly and Smith, to review the terms of any proposed financing to be obtained by the Company in order to ensure that the Company's efforts with respect to any such financing transaction were reasonable, unbiased and made on an informed basis and that all reasonable alternatives were considered and that such transactions were fair from a financial point of view to all holders of the Company's securities. During the period from November 3 to November 11, 2003, the Independent Committee convened three meetings. Also participating in such meetings was special legal counsel to the Independent Committee and Peter Clemens, the Company's Chief Financial Officer. At each of such meetings, Mr. Clemens provided an update to the Independent Committee as to the Company's capital raising efforts and advised that the Company awaited a proposed term sheet from Galen Partners, Care Capital, Essex Woodlands and Oracle Strategic Partners providing the terms of a proposed financing for the Company. Mr. Clemens also advised the Independent Committee as to the Company's cash position and cash burn rate. On November 11, 2003, a teleconference was held with representatives of each Oracle Strategic Partners, Care Capital, Essex Woodlands and Galen Partners, the Company's Chief Executive Officer, the Company's Chief Financial Officer and Company legal counsel to discuss, in general, the terms of a proposal for the investor group to provide financing to the Company. Such discussions were conceptual in nature. The representatives of the investor group indicated that such group may be willing to provide up to $15 million in new debenture financing on terms to be determined, provided that the $21.4 million term loan agreement (the "Watson Term Loan") with Watson Pharmaceuticals ("Watson") could be restructured on terms acceptable to the investors. The teleconference between the parties concluded with the investor group indicating that a draft term sheet relating to a proposed financing would be provided to the Company. On November 12, 2003, a representative of Care Capital provided to the Company and Company counsel a summary of terms relating to a proposed debenture financing to provided by Galen Partners, Care Capital, Essex Woodlands and Oracle Strategic Partners. The summary of terms was delivered by the investor group with the express understanding that it was to serve solely as a basis of introductory discussions and that definitive financial terms were to be negotiated on a going-forward basis. In general, the summary of terms provided for a financing in the form of 8% convertible senior secured debentures. The debentures would be convertible into the Company's Common Stock at a conversion price to be negotiated between the parties. The summary of terms contemplated that aggregate financing of approximately $15 million would be provided, that the debentures would be secured by a lien on all assets of the Company and that the financing documents would contain customary affirmative and negative covenants and dilution protections. The summary of terms also provided that it was a condition to the completion of any such financing that the Watson Term Loan be retired in full in consideration for a payment to Watson not exceeding $5 million. Over the next few days, Management reviewed with Company counsel the summary of terms and evaluated the financing proposal presented by the investor group. In the interim, the Company's Chief Executive Office and Chief Operations Officer coordinated with representatives of each of Care Capital, Essex Woodlands and Galen Partners to facilitate such parties' due diligence investigation of the Company's proprietary technologies. Additionally, on November 14, 2003, the Board of Directors held an informational teleconference in order for Management to advise the Board as to the status of discussions with the investor group relating to the summary of terms received on November 12, 2003. On November 18, 2003, the Company's Chief Executive Officer participated in a teleconference with representatives of Care Capital and Essex Woodlands to discuss, in general, the summary of terms dated November 12, 2003 and the condition to the completion of any such financing that the Watson Term Loan be retired at a substantial discount. The representatives of Care Capital and Essex Woodlands participating in the teleconference again advised the Company that the summary of terms provided on November 12, 2003 was 30

intended solely to commence discussions as to the terms of any proposed financing and that following a more detailed internal review of the financing by the investor group, a more comprehensive summary of terms would be provided to the Company. On the same date, the Independent Committee of the Board convened a meeting at which the Company's Chief Financial Officer participated. Mr. Clemens advised the Independent Committee as to the current status of the Company's capital raising efforts as well as ongoing discussions with Watson in an effort to restructure the Watson Term Loan and retire all or a significant portion of such indebtedness at a substantial discount. On November 20, 2003, a teleconference was held between Company counsel and special legal counsel for the Independent Committee. During the call, Company counsel provided an overview of the summary of terms dated November 12, 2003 received from the investor group and the November 18, 2003 teleconference among the Company's Chief Executive Officer and the representatives of the investor group. Pending the Company's receipt of a definitive term sheet, the investor group continued their due diligence investigation of the Company's proprietary technologies. In addition, on November 25, 2003, the Board of Directors of the Company convened a meeting to, among other things, review the Company's financial condition, current cash resources, the status of the Company's capital raising efforts, the discussions with the investor group and the summary of terms dated November 12, 2003 provided by the investor group. Management also advised the Board that the Company expected a definitive term sheet relating to a proposed financing from Galen, Care Capital and Essex Woodlands (the "Lead 2004 Investors") by the end of November. On December 1, 2003, Baker & McKenzie, as lead legal counsel for the Lead 2004 Investors ("Lead Investor Counsel") delivered to Company counsel a discussion draft of a term sheet containing the general terms of a debenture financing proposed to be provided to the Company by the Lead 2004 Investors. In general, the December 1, 2003 term sheet provided for the Company's issuance of up to $12 million in 5% convertible senior secured debentures, which debentures would have a liquidation preference equal to five times their principal amount, be fully secured by a lien on all of the Company's assets and mature on June 30, 2005. It was also contemplated that such debentures would be convertible on terms substantially identical to the Company's 2002 Debentures and that the investors would receive Common Stock purchase warrants exercisable for such number of shares as equaled 125% of the principal amount of the debentures issued by the Company. The term sheet also provided that the investors would be entitled to appoint up to six of the Company's 11 Board positions. Among other customary conditions to the completion of the debenture financing, it was condition that the Lead 2004 Investors acquire from Watson the promissory notes issued by the Company under the Watson Term Loan. On the date of receipt of the term sheet, Company counsel and counsel for each of Galen Partners, Essex Woodlands and Care Capital convened a conference call to review in general the December 1, 2003 term sheet and respond to questions from Company counsel. The parties did not negotiate any specific provisions of the term sheet during this call. Following a review of the December 1, 2003 term sheet with Company counsel, Andrew Reddick, the Company's Chief Executive Officer, spoke with a representative of Care Capital by telephone. During the call, Mr. Reddick advised that, based on his discussions with Company counsel, the debenture structure and five times liquidation preference proposed by the Lead 2004 Investors in the December 1, 2003 term sheet would likely have original issue discount (deemed interest) ramifications that would be unacceptable to the Company and likely, the Lead 2004 Investors. Mr. Reddick requested that Care Capital consult with the other representatives of the Lead 2004 Investors in an effort to provide a term sheet that would contemplate a financing structure involving the Company's equity securities as opposed to debentures and warrants. On December 2, 2003, the Board of Directors convened a teleconference to discuss, among other things, the Company's cash flow and cash reserves and the status of discussions with the Lead 2004 Investors. In the course of the Board's general review of the December 1 term sheet, Company counsel advised the Board that in view of the implication of original issue discount contained in the term sheet, it was likely that the financing structure proposed by the Lead 2004 Investors would be substantially revised. The Board authorized Management to continue discussions with the Lead 2004 Investors in an effort to identify a financing structure and financing terms acceptable to the Company. 31

On December 3, 2003, Lead Investor Counsel contacted Company counsel by telephone to discuss the general framework of a revised financing structure under consideration by the Lead 2004 Investors. Lead Investor Counsel advised that the structure would likely take the form of secured notes that would be subordinate to the existing Watson Term Loan. The secured notes would be convertible into senior participating and convertible series A preferred stock having a fives times liquidation preference, five times conversion right and five times participation right. Lead Investor Counsel further advised that the financing would be conditioned on the holders of the Company's 1998-2002 Debentures agreeing to convert all such debentures into classes of junior preferred stock. Lead Investor Counsel further advised that it was contemplated that the Lead 2004 Investors would acquire from Watson, at a discount to be negotiated with Watson, the promissory notes issued by the Company under the Watson Term Loan. On December 4, 2003, Lead Investor Counsel and a representative of Essex Woodlands contacted Company counsel by telephone to further discuss the financing structure under consideration by the Lead 2004 Investors. During the call, Lead Investor Counsel and Essex Woodlands provided an overview of the general terms of the such financing structure, consisting of the following: - A financing in the form of senior secured notes (subordinated to the Watson Term Loan indebtedness), bearing interest at the Applicable Federal Rate on the date of issuance. The notes would be convertible into Series A Preferred Shares which would be senior to all other equity securities of the Company and have a five times liquidation preference, a five times conversion right and a five times participation right. - The holders of the 1998-2002 Debentures would agree to convert such debentures into series of preferred stock which would be junior to the Series A Preferred Shares, have a one time liquidation preference and be convertible into the Company's Common Stock at the conversion prices currently provided for in such debentures. - The Lead 2004 Investors would provide aggregate funding under the Senior Secured Notes of approximately $10 million and such notes would convert automatically into the Series A Preferred Shares upon receipt of shareholder approval of the Company's Charter amendment to create the Series A Preferred Shares and Junior Preferred Shares. - The Lead 2004 Investors would acquire from Watson the promissory notes in the aggregate principal amount of $21.4 million issued by the Company under the Watson Term Loan on terms acceptable to the Lead 2004 Investors and that such notes would remain outstanding. - The Board of Directors would be comprised of six members, four of whom would be appointed by the Lead 2004 Investors. On December 5, 2003, Lead Investor Counsel provided a discussion draft of a term sheet dated December 5, 2003. The December 5, 2003 term sheet was consistent in all material respects with the outline of terms discussed with Company counsel in the prior teleconferences held with Lead Investor Counsel on December 3 and December 4, 2003. A copy of the draft term sheet was provided to the Independent Committee and its special legal counsel. On December 5, 2003, the Independent Committee convened a meeting to review the draft term sheet dated December 5, 2003 provided by the Lead 2004 Investors. During the meeting, each of the Company's Chief Executive Officer and Chief Financial Officer and Company counsel reviewed the material issues raised by the December 5 term sheet, including (i) the need to include a mandatory conversion provision such that all of the Company's preferred shares would convert into Common Stock upon the satisfaction of an agreed upon trading value for the Common Stock, (ii) the need to extend the proposed July 31, 2004 maturity date of the senior secured notes in order to provide the Company with sufficient time to obtain shareholder approval to amend its Charter to authorize the preferred shares, (iii) the need to reduce the five times multiple for each of the liquidation preference, conversion right and participation right of the Series A Preferred Shares contained in the term sheet, (iv) the need to include a waiver of the dilution protections provided to each of the Company's outstanding debentureholders, and (v) that the Company be permitted to use the proceeds of the financing to retire the promissory notes issued by the Company under the Watson Term Loan. During the 32

meeting, it was agreed that special legal counsel for the Independent Committee would prepare a memorandum of issues relating to the December 5, 2003 term sheet for review by the Independent Committee. The Independent Committee convened a meeting on December 8, 2003 to review the memorandum dated December 8 prepared by special legal counsel for the Independent Committee (the "Issue Memorandum"). The Independent Committee adopted the Issue Memorandum and requested that Management and Company counsel further negotiate the issues contained in the Issue Memorandum with the Lead 2004 Investors and their counsel. In summary, the Issue Memorandum addressed the following: - The need for minimum aggregate additional financing of at least $7.5 million. - A maturity date of the senior secured notes of July 31, 2004, subject to extension for up to 90 days to complete SEC review of the Company's proxy statement soliciting shareholder approval of the Charter amendment to authorize the preferred shares. - That the proposed five times multiple for each of the liquidation preference, conversion right and participation right of the Series A Preferred Shares be reduced to a multiple in the range of 1.5 to 1. - The waiver of the dilution protections provided to the holders of the 1998-2002 Debentures relating to the proposed financing. - A limitation on legal and other professional fees payable by the Company on behalf of the Lead 2004 Investors. - The automatic conversion of all preferred shares based on a trading value of the Company's Common Stock, in an amount to be mutually agreed. - The Company's direct purchase from Watson of the promissory notes issued by the Company under the Watson Term Loan with the proceeds of the financing provided by the Lead 2004 Investors. On December 8, 2003, Company counsel provided the Issue Memorandum to the Lead Investor Counsel. Company counsel and Lead Investor Counsel convened a teleconference on December 8, 2003 to review the Lead 2004 Investors' response to each of the requests of the Independent Committee contained in the Issue Memorandum. Lead Investor Counsel advised that the Lead 2004 Investors were willing to extend the maturity date of the senior secured notes, waive the dilution protections relating to the 1998-2002 Debentures, and limit the professional fees payable by the Company on behalf of the Lead 2004 Investors. Lead Investor Counsel further advised, however, that the Lead 2004 Investors were unwilling to revise the December 5, 2003 term sheet to address the remaining requests of the Independent Committee contained in the Issue Memorandum. Company counsel requested that Lead Investor Counsel again discuss the remaining issues described in the Issue Memorandum with the Lead 2004 Investors in an effort to reach mutually agreeable terms. On the same date, the Company's Chief Executive Officer contacted a representative of Essex Woodlands to review the issues outlined in the Issue Memorandum. During such discussions, Essex Woodlands indicated that the Lead 2004 Investors would consider structuring the acquisition of the Company's promissory notes issued under the Watson Term Loan to provide that, following the Lead 2004 Investor's acquisition of such notes for a payment of $5 million to Watson, the remaining $16.4 million of indebtedness under the Watson Term Loan would be forgiven. Essex Woodlands also advised that it would discuss with the other Lead 2004 Investors the aggregate amount of the financing that would be provided in an effort to satisfy the Company's request for net funding of approximately $7.5 million (after giving effect to any payments made by the Company to Watson to retire $16.4 million of indebtedness under the Watson Term Loan). On December 11, 2003, Lead Investor Counsel provided a revised discussion draft term sheet to Company counsel. The revised term sheet addressed some of the issues raised by the Independent Committee in its Issue Memorandum, including: - Providing for aggregate funding of up to $14.0 million of which a minimum of $11.0 million would be funded by the Lead 2004 Investors at the initial closing of the financing. 33

- Permitting the Company to use $4.0 million of the proceeds raised in the financing to retire approximately $16.4 million of the indebtedness under the Watson Term Loan. The remaining $5.0 million indebtedness under the Watson Term Loan would be purchased from Watson directly by the Lead 2004 Investors. - Extending the maturing date of the senior secured notes to be issued in the financing from July 31, 2004 by a period of up to 90 days thereafter. - Limiting the legal and other professional fees payable by the Company on behalf of the Lead 2004 Investors. The December 11, 2003 term sheet retained the proposed five times multiple for each of the liquidation preference, conversion right and participation right of the Series A Preferred Shares. Following Management's review of the December 11, 2003 term sheet with Company counsel, on December 11, 2003, Company counsel telephoned Lead Investor Counsel to convey comments and proposed changes to the December 11 term sheet. The material comments consisted of: - A reduction in the five times multiple for each of the liquidation preference, conversion right and participation right for the Series A Preferred Shares. - The mandatory conversion of all preferred shares based on a trading value of the Company's Common Stock in an amount to be mutually agreed. - That, upon the Lead 2004 Investors' purchase of the remaining $5.0 million of indebtedness under the Watson Term Loan, the maturity date of such indebtedness be extended from March 31, 2006 to June 30, 2007. - That interest under the remaining $5.0 million Watson note be payable in the Company's Common Stock. - That the Lead 2004 Investors forbear from the exercise of rights and remedies under the acquired $5.0 million Watson note upon the occurrence of non-monetary events of default under such note. Discussions on these issues continued by telephone between Company counsel and Lead Investor Counsel as well as between the Company's Chief Executive Officer and representatives of Essex Woodlands, acting in its capacity as the primary contact for the Lead 2004 Investors. On December 12, 2003, Lead Investor Counsel provided to Company counsel a revised draft of the term sheet. The December 12 term sheet retained the proposed five times multiple for each of the liquidation preference, conversion right and participation right for the Series A Preferred Shares. Such term sheet did, however, address the amendments requested by the Company with respect to the remaining $5.0 million note issued under the Watson Term Loan. The Term sheet provided that, after the purchase of such note by the Lead 2004 Investors, the maturity date of the note would be extended from March 31, 2006 to June 30, 2007, and future interest payments under the note would be payable in the Company's Common Stock based on the trading value of Common Stock at the time of each interest payment. The note would also be amended to provide for forbearance from the exercise of rights and remedies upon a non-monetary event of default by the Company, subject to certain customary exceptions. A meeting of the Independent Committee was held on December 14, 2003, to, among other things, review the December 12, 2003 term sheet received from the Lead 2004 Investors. While acknowledging that the terms contained in the December 12 term sheet were more favorable to the Company than those contained in earlier versions of the term sheet, the Independent Committee requested that Management continue to negotiate with the Lead 2004 Investors in an effort to reduce the proposed five times multiple for each of the liquidation preference, the conversion right and the participation right of the Series A Preferred Shares and to provide for the automatic conversion of all preferred shares based on a mutually agreeable trading value of the Company's Common Stock. During the period from December 15, 2003 through December 18, 2003, the Company's Chief Executive Officer held a number of telephone conferences with representatives of the Lead 2004 Investors in an effort to negotiate reductions to the liquidation preference, conversion right and 34

participation right of the Series A Preferred Shares and to provide for an automatic conversion mechanism relating to the preferred shares. During the same period, Company counsel and Lead Investor Counsel held a number a teleconferences relating to these issues. On December 17, 2003, a representative of Care Capital, the Company's Chief Executive Officer, and certain holders of the Company's 1998-2002 debentures met to discuss the liquidation preference, conversion right and participation right of the Series A Preferred Shares contained in the December 12, 2003 term sheet. Following extended discussions on these items, Care Capital advised that in the absence of a five times multiple for each of the liquidation preference and the conversion right for the Series A Preferred Shares, the Lead 2004 Investors would not provide financing to the Company. Care Capital advised, however, that the Lead 2004 Investors would agree to a reduction of the participation right for the Series A Preferred Shares from 5 times to 1.5 times. On December 19, 2003, special legal counsel for the Independent Committee and Company counsel contacted Lead Investor Counsel by telephone to discuss a proposal to include a mandatory conversion mechanism relating to the preferred shares. Following a number of teleconferences on December 19, 2003 among counsel for the Lead 2004 Investors, the Company and the Independent Committee, the Lead 2004 Investors agreed to provide for the automatic conversion of all preferred shares into the Company's Common Stock provided that the Common Stock trades at an average price of $2.80 per share for any 30 consecutive trading day period and the average daily trading value of the Company's Common Stock during such 30 day trading period equals or exceeds $1.75 million. On December 19, 2003, Lead Investor Counsel provided Company counsel with a definitive term sheet relating to the proposed financing. Such term sheet reflected the changes previously discussed and agreed to in concept by the parties, all as described above. The Independent Committee convened a meeting on December 20, 2003 to review the definitive term sheet provided by the Lead 2004 Investors dated December 19, 2003. In addition to a discussion of the mandatory conversion feature for the preferred shares contained in the term sheet, the Independent Committee reviewed each of the issues previously raised by the Independent Committee in its Issue Memorandum dated December 8, 2003. Following a detailed review and discussion of such issues and the final terms contained in the December 19, 2003 term sheet, and considering the extensive information reviewed by the Independent Committee (See "Information Reviewed by the Independent Committee" below) and the fairness opinion of Agema LLC, the independent financial advisor retained by the Independent Committee, the Independent Committee unanimously adopted a resolution approving the terms of the December 19, 2003 term sheet and the transactions contemplated therein. At a meeting of the Board of Directors held on December 21, 2003, Mr. Sumner, as Chairman of the Independent Committee, presented to the Board the unanimous resolution of the Independent Committee approving the terms of the December 19, 2003 term sheet and the transactions contemplated therein. After extensive discussion of the terms of the December 19, 2003 term sheet and the findings of the Independent Committee, including the fairness opinion provided by Agema LLC, the Board of Directors approved and ratified the December 19, 2003 term sheet. Each of Messrs. Thangaraj, Karabelas, Wesson, Conjeevaram and Shroff (each being a designee of Care Capital, Essex Woodlands and Galen Partners) abstained from such action. During the period from December 31, 2003 through January 7, 2004, Company counsel and Lead Investor Counsel exchanged drafts of the relevant transaction documents prepared by such counsel intended to memorialize the December 19, 2003 term sheet. Between January 9, 2004 and January 19, 2004, Lead Investor Counsel and Company counsel exchanged marked drafts of the various documents and participated in numerous telephone conferences in an effort to finalize the financing agreements. During this period, no changes were made to the financial or other material terms contained in the December 13, 2003 term sheet. Also during this period, Company counsel, Lead Investor Counsel and counsel for Watson finalized the agreements by which the Company would retire $16.4 million of the Watson Term Loan indebtedness and Watson would convey the remaining $5.0 million of such indebtedness to the Lead 2004 Investors. 35

On January 20, 2004, the Board of Directors convened a meeting to, among other things, review the status of the 2004 Debenture Offering and the completion of the documentation relating to the such transaction. At such meeting, the Board approved the terms of such documentation and authorized Management to negotiate such changes to the financing documents and relating agreements as were necessary to conclude the 2004 Debenture Offering. Each of Messrs. Wesson, Conjeevaram, Shroff, Thangaraj and Karabelas abstained from such action as such directors are designees of the Lead 2004 Investors. Any changes made to the definitive 2004 Purchase Agreement and related agreements during the period subsequent to the receipt of the approval of the Board of Directors were not material and did not alter the financial terms of the 2004 Debenture Offering as previously discussed and approved by the Board. During the period from January 20 through February 5, 2004, legal counsel for the Company, the Lead 2004 Investors and Watson finalized the 2004 Debenture Offering documents for execution. On February 6, 2004, the 2004 Purchase Agreement and related transaction documents were executed and held in escrow pending the completion of the funding of the transaction on February 10, 2004, at which time all documents were released from escrow. 2004 DEBENTURE OFFERING On February 10, 2004, the Company consummated a private offering of convertible senior secured debentures (the "2004 Debentures") for an aggregate purchase price of approximately $12.3 million (the "2004 Debenture Offering"). The 2004 Debentures were issued pursuant to a certain Debenture and Share Purchase Agreement dated as of February 6, 2004, as amended June 6, 2004 (the "2004 Purchase Agreement") by and among the Company, the Lead 2004 Investors and each of the purchasers listed on the signature page thereto. The 2004 Purchase Agreement provided for the Company to issue additional 2004 Debentures in the principal amount of up to approximately $1.7 million on or before June 5, 2004 (the date 120 days from the date of the 2004 Purchase Agreement) provided that the aggregate principal amount of the 2004 Debentures issued pursuant to the 2004 Purchase Agreement shall not exceed $14.0 million without the consent of the holders of 60% of the principal amount of the 2004 Debentures then held by the Lead 2004 Investors. On April 14, 2004 and May 28, 2004, the Company completed an additional closing under the 2004 Purchase Agreement pursuant to which the Company issued additional 2004 Debentures in the aggregate principal amount of $579,000 and $1.121 million, respectively, bringing the aggregate principal amount of 2004 Debentures issued by the Company under the 2004 Purchase Agreement to $14.0 million. On June 6, 2004, the 2004 Purchase Agreement was amended to (i) increase the principal amount of the 2004 Debentures issuable under the 2004 Purchase Agreement from $14.0 million to $17.5 million, and (ii) extend the date for the issuance of additional 2004 Debentures from June 5, 2004 to June 30, 2004 (the "2004 Purchase Agreement Amendment"). Of the approximate $14.0 million in 2004 Debentures issued in the 2004 Debenture Offering as of June 1, 2004, $2.0 million of 2004 Debentures were issued in exchange for the surrender of a like amount of principal plus accrued and unpaid interest outstanding under the Company's 5% convertible senior secured debentures issued to the Lead 2004 Investors in November and December, 2003 pursuant to the Letter of Support. The Company will use the net proceeds of the 2004 Debenture Offering to fund working capital requirements. The 2004 Debentures, issued at par, bear interest at the rate of 1.62% per annum, the short term Applicable Federal Rate on the date of issuance, and are secured by a lien on all the Company's and its subsidiaries' assets. The 2004 Debentures (including the principal amount plus accrued interest at the date of conversion) will convert automatically into the Company's Series A Preferred shares immediately following the Company's receipt of shareholder approval of this Proposal 2 to restate the Company's Charter (the "Charter Amendment") and the filing of the Charter Amendment with the Office of the New York Department of State (the date of such filing, the "Charter Amendment Filing Date") as provided in the 2004 Purchase Agreement, the Charter Amendment and the Conversion Agreement (as discussed below). The 2004 Debentures will convert into Series A Preferred shares at a price per share (the "Series A Conversion Price") of $0.6425, representing the average of the closing bid and asked prices of the Company's Common Stock for 36

the twenty (20) trading days ending February 4, 2004, as reported by the Over-the-Counter ("OTC") Bulletin Board. The closing bid price for the Company's Common Stock on January 20, 2004, the date of Board approval of the 2004 Debenture Offering, was $0.64 per share. The Series A Conversion Price is subject to adjustment from time to time, as described below under the caption "Terms of Preferred Stock". Based on the $0.6425 Series A Conversion Price, and estimating the interest accrual under the 2004 Debentures prior to the Charter Amendment Filing Date, the 2004 Debentures with an aggregate principal amount of $17.5 million would be convertible into an aggregate of approximately 27.2 million Series A Preferred shares. As of February 10, 2004, the date of the initial closing of the 2004 Purchase Agreement, the Company had issued an outstanding an aggregate of approximately $87.7 million in principal amount of 5% convertible senior secured debentures maturing March 31, 2006 issued pursuant to three separate Debenture Purchase Agreements dated March 10, 1998, as amended (the "1998 Debentures"), May 26, 1999, as amended (the "1999 Debentures") and December 20, 2002 (the "2002 Debentures"), respectively. The 1998 Debentures, 1999 Debentures and 2002 Debentures are referred to collectively as the "1998-2002 Debentures". The terms of the 1998-2002 Debentures are consistent in all material respects with the 2004 Debentures and are described below under the caption "Description of Debentures". After giving effect to the Company's issuance of additional 5% convertible senior secured debentures in satisfaction of interest payments on the 1998-2002 Debentures, as of February 10, 2004 , the 1998-2002 Debentures were convertible into an aggregate of approximately 190.4 million shares of the Company's Common Stock. After considering the Company's other outstanding convertible securities, as of June 1, 2004, the Company had committed to issue approximately 277,593,519 shares of Common Stock in excess of its currently authorized 80.0 million shares of Common Stock. Simultaneous with the execution of the 2004 Purchase Agreement, and as a condition to the initial closing of the 2004 Purchase Agreement, the Company, the investors in the 2004 Debentures and each of the holders of the 1998-2002 Debentures execute a certain Debenture Conversion Agreement dated as of February 6, 2004 (the "Conversion Agreement"). In accordance with the terms of the Conversion Agreement, each holder of 2004 Debentures agreed to convert the 2004 Debentures held by such holder into the Company's Series A Preferred shares and each holder of 1998-2002 Debentures agreed to convert the 1998-2002 Debentures held by such holder into the Company's Junior Preferred Shares. The Conversion Agreement provides, among other things, for the automatic conversion of the 2004 Debentures and the 1998-2002 Debentures (collectively, the "Outstanding Debentures") into the appropriate class of Preferred Stock immediately following the Company's receipt of shareholder approval to the Charter Amendment pursuant to this Proposal 2 and the filing of the Charter Amendment with the Office of the New York Department of State. Under the Conversion Agreement, the holders of approximately $6.6 million in principal amount of 2002 Debentures issued pursuant to the Letter of Support during 2003 will convert such 2002 Debentures (plus accrued and unpaid interest) into Series B Preferred Shares. Of the remaining approximate $81.1 million in principal amount of the 1998-2002 Debentures, approximately $31.6 million is comprised of 1998 Debentures, approximately $21.8 million is comprised of 1999 Debentures and approximately $27.7 million is comprised of 2002 Debentures. The 1998 Debentures (plus accrued and unpaid interest) will be converted into Series C-1 Preferred shares. The 1999 Debentures (plus accrued and unpaid interest) will be converted into Series C-2 Preferred shares. The 2002 Debentures (plus accrued and unpaid interest) shall be converted into Series C-3 Preferred shares. The number of Junior Preferred Shares to be received by each holder of 1998-2002 Debentures is based on the respective prices at which the 1998-2002 Debentures were convertible into Common Stock. The 2002 Debentures issued pursuant to the Letter of Support in 2003 have a conversion price of $0.3420 per share. The closing bid price for the Company's Common Stock on December 17, 2002, the date of Board approval of the 2002 Purchase Agreement, was $0.98 per share. The 1998 Debentures, 1999 Debentures and the remaining balance of the 2002 Debentures have conversion prices of $0.5776, $0.5993 and $0.3481 per share, respectively. The closing bid price for the Company's Common Stock on February 19, 1998, May 20, 1999 and 37

December 17, 2002, the dates of Board approval of the debenture purchase agreements pursuant to which the 1998 Debentures, the 1999 Debentures and the 2002 Debentures were issued, was $2.63, $1.94 and $0.98 per share, respectively. Based on the respective conversion prices of the 1998-2002 Debentures, and estimating the interest accrual on the 1998-2002 Debentures prior to the Charter Amendment Filing Date, the 1998-2002 Debentures are convertible into an aggregate of approximately 20 million Series B Preferred shares, 56.5 million Series C-1 Preferred shares, 37.5 million Series C-2 Preferred shares and 80.9 million Series C-3 Preferred shares. DILUTION TO COMMON SHAREHOLDERS AND HOLDERS OF THE 1998-2002 DEBENTURES. Prior to the completion of the 2004 Debenture Offering, the Company had issued and outstanding an aggregate of approximately $87.7 million in principal amount of 1998-2002 Debentures which were convertible into an aggregate of approximately 190.4 million shares of the Company's Common Stock. After giving effect to the conversion rights of the 1998-2002 Debentures, and the Company's stock options and warrants then outstanding, the aggregate ownership interest in the Company held by holders of the 1998-2002 Debentures as a group was approximately 76.2% (calculated on a fully-diluted basis). As of February 9, 2004, the day preceding the initial closing of the 2004 Purchase Agreement, the Company's public, non-affiliated shareholders as a group held an aggregate of approximately 14,238,911 shares, representing approximately 5.7% of the Company's Common Stock (calculated on a fully-diluted basis). The following table provides the ownership percentages in the Company held by the 2004 Debentureholders as a group, the holders of the 1998-2002 Debentures as a group and the Company's public, non-affiliated shareholders as a group, both before and after giving effect to the completion of the 2004 Debenture Offering (calculated on a fully-diluted basis).

FULLY DILUTED OWNERSHIP PERCENTAGE IN THE COMPANY AFTER THE COMPLETION OF THE 2004 DEBENTURE OFFERING --------------------------------------- FULLY DILUTED OWNERSHIP PERCENTAGE ASSUMES ASSUMES IN THE COMPANY BEFORE THE COMPLETION $14.0 MILLION $17.5 MILLION SECURITY HOLDERS OF THE 2004 DEBENTURE OFFERING IN 2004 DEBENTURES IN 2004 DEBENTURES - ---------------- ------------------------------------ ------------------ ------------------ - - 2004 Debentureholders as a Group... -- 30.5% 35.4% - - 1998-2002 Debentureholders as a Group.............................. 76.2% 53.3% 49.5% - - Public, Non-Affiliated Shareholders as a Group......................... 5.7% 4.0% 3.7%
PROCEEDS OF 2004 DEBENTURE OFFERING As of June 1, 2004, the Company had issued 2004 Debentures in the aggregate principal amount of $14 million. Approximately $2.0 million in principal amount of the 2004 Debentures were issued in exchange for the surrender of a like amount of principal plus accrued interest outstanding under Company debentures issued in November and December 2003 pursuant to the Letter of Support. Of the $12 million in gross proceeds received by the Company under the 2004 Debenture Offering, approximately $4.3 million was paid to Watson to retire $16.4 million of the Company's indebtedness to Watson under the $21.4 million Watson Term Loan Agreement. (See "Interests of Investors in the 2004 Debenture Offering"). After giving effect to the payment to Watson and the satisfaction of legal and other professional fees of approximately $400,000, assuming no further 2004 Debentures are issued, the Company estimates that it will realize net proceeds from the 2004 Debenture Offering of approximately $7.3 million. As described under Proposal 4 under the caption "Proceeds of the Sale of the Congers Facilities Assets", the Company estimates that it will realize net proceeds from the asset sale transaction of approximately $2.3 million. The net proceeds of each of the asset sale transaction and the 2004 Debenture Offering received as of June 1, 2004, aggregating approximately $9.1 million, combined with the Company's other cash balances and reduced by operating expenses though May 31, 2004, provided the Company with approximately $7.3 million in cash reserves as of June 1, 2004 to fund the development and commercialization of its 38

proprietary technologies. Set forth below is a summary of the Company's estimated allocation of its cash resources as of June 1, 2004 to the development of its proprietary technologies and funding of operations:

USE ITEM AMOUNT - -------- ------------ Research & Development of ADF Technology Product, including clinical trials........................................... $ 3,250,000 Research & Development of Opiod Synthesis Technologies...... $ 600,000 Administration (i.e., insurance, finance, investor relations, employee benefits, legal, market research)..... $ 2,000,000 Personnel (i.e., salaries, bonuses, payroll taxes).......... $ 1,450,000 ------------ $7.3 million ============
While no assurance can be given, Management estimates that the existing cash on hand at June 1, 2004 of $7.3 million will fund activities through the first quarter of 2005. As of such time, the Company estimates that it will have completed initial clinical trials of a product incorporating its ADF Technology and will have entered into one or more licensing agreements for such product with a third party. The Company expects that the payments to be derived from such licensing agreements will provide the Company with the necessary additional funding to continue operations and to expand and expedite its development efforts. The ability of the Company to enter into a license agreement with a third party and the consideration to be received by the Company as part of any such agreement is primarily dependent upon the favorable outcome of the initial clinical trials of the Company's products, of which no assurance can be given. DESCRIPTION OF CHARTER AMENDMENT Prior to giving effect to the Charter Amendment described in this Proposed 2 and attached as Appendix C to this Proxy Statement, the Company's Charter provides for authorized capital stock consisting of 80.0 million shares of Common Stock, $.01 par value per share. The Charter provides that each share of Common Stock shall entitle the holder thereof to one vote on each matter submitted to a vote of stockholders of the Company. In addition, the Company's 1998 Debentures and 1999 Debentures have the right to vote with holders of the Company's Common Stock on all matters submitted to stockholders of the Company on as-converted basis giving effect to the conversion of the 1998 Debentures and 1999 Debentures into Common Stock (without the requirement of such conversion) as of the record date set for the shareholder vote. No shares of Preferred Stock are currently authorized for issuance under the Charter. On January 20, 2004, the Board of Directors unanimously approved and recommended that the Company's shareholders consider and approve the Charter Amendment providing for (i) an increase in the number of authorized shares of capital stock of the Company from 80.0 million to 940.0 million, consisting of 650.0 million shares of Common Stock, $.01 par value per share, and 290.0 million shares of Preferred Stock, $.01 par value per share, and (ii) designating 45.0 million shares of the Preferred Stock as Series A Preferred, designating 25.0 million shares of the Preferred Stock as Series B Preferred, designating 70.0 million shares of the Preferred Stock as Series C-1 Preferred, designating 50.0 million shares of the Preferred Stock as Series C-2 Preferred and designating 100.0 million shares of the Preferred Stock as Series C-3 Preferred, with each class of Preferred Stock to have the rights, preferences and limitations described in the Charter Amendment. The Series A Preferred shares have a liquidation preference equal to five (5) times the initial $0.6425 Series A Conversion Price (the "Series A Liquidation Preference"). In addition, the Series A Preferred shares are convertible into the Company's Common Stock, with each Series A Preferred share convertible into five shares of the Company's Common Stock, subject to adjustment, from time to time, pursuant to the dilution protections described below under the caption "Terms of Preferred Stock". The closing bid price for the Company's Common Stock on January 20, 2004, the date of Board approval of the 2004 Debenture Offering, was $0.64 per share. Without limiting the Series A Liquidation Preference, the holders of Series A Preferred shares also have the right to participate with the holders of the Company's Common Stock upon the occurrence of a liquidation event, including the Company's merger, sale of all or substantially all of its assets 39

or a change of control transaction, on an as-converted basis (but for these purposes only, assuming the Series A Preferred shares to be convertible into only thirty percent (30%) of the shares of Common Stock into which they are otherwise then convertible). The holders of Series A Preferred shares also have the right to vote as part of a single class with all holders of the Company's voting securities on all matters to be voted on by such security holders. Each holder of Series A Preferred shares will have such number of votes as shall equal the number of votes he would have had if such holder converted all Series A Preferred shares held by such holder into shares of Common Stock immediately prior to the record date relating to such vote. The Junior Preferred Shares have a liquidation preference equal to one (1) time the principal amount plus accrued and unpaid interest of the 1998-2002 Debentures converted into Junior Preferred Shares The liquidation preference of the Series B Preferred has priority over, and will be satisfied prior to, the liquidation preference of the Series C Preferred. The liquidation preference for each class of the Junior Preferred Shares is equal to the conversion prices of such shares. The Junior Preferred Shares are convertible into the Company's Common Stock, with each Junior Preferred Share convertible into one share of Common Stock. The holders of the Junior Preferred Shares have the right to vote as part of the single class with all holders of the Company's Common Stock and the holders of the Series A Preferred on all matters to be voted on by such stockholders, with each holder of Junior Preferred Shares having such number of votes as shall equal the number of votes he would have had if such holder had converted all Junior Preferred Shares held by such holder into Common Stock immediately prior to the record date relating to such vote. The Charter Amendment also provides for the elimination of the voting rights of the holders of the 1998 Debentures and the 1999 Debentures. Effective on the Charter Amendment Filing Date, all of the 1998 Debentures and 1999 Debentures will convert automatically into Junior Preferred Shares. As a result, no 1998 Debenture or 1999 Debentures will remain outstanding following the Charter Amendment Filing Date for which such voting rights could be exercised. REFERENCE IS MADE TO THE DESCRIPTION PROVIDED UNDER THE CAPTION "TERMS OF PREFERRED STOCK" AS WELL AS THE COPY OF THE CHARTER AMENDMENT ATTACHED AS APPENDIX C TO THIS PROXY STATEMENT FOR A MORE DETAILED DESCRIPTION OF THE TERMS OF THE PREFERRED STOCK. As of June 1, 2004, the Company had 21,716,025 shares of Common Stock issued and outstanding. In addition, as of June 1, 2004, the Company had issued Common Stock purchase options and warrants exercisable for approximately 36,492,654 shares of Common Stock. Assuming the receipt of shareholder approval of the Proposal 2 and after giving effect to the conversion of the Company's Outstanding Debentures into Preferred Stock, (including an estimate of accrued interest under the Outstanding Debentures prior to the Charter Amendment Filing Date), the Company's outstanding shares of Common Stock and Preferred Stock, 40

BOARD RECOMMENDATION THE COMPANY'S BOARD OF DIRECTORS HAS APPROVED THE CHARTER AMENDMENT TO (I) INCREASE THE NUMBER OF AUTHORIZED SHARES OF THE COMPANY'S COMMON STOCK FROM 80.0 MILLION SHARES TO 650.0 MILLION SHARES IN ORDER TO PROVIDE SUFFICIENT AUTHORIZED SHARES OF COMMON STOCK FOR ISSUANCE UPON CONVERSION OF THE COMPANY'S PREFERRED STOCK AND THE EXERCISE OF THE COMPANY'S COMMON STOCK PURCHASE OPTIONS AND WARRANTS, AND (II) PROVIDE FOR ADDITIONAL CAPITAL STOCK CONSISTING OF 290.0 MILLION SHARES OF CONVERTIBLE PREFERRED STOCK, OF WHICH 45.0 MILLION SHARES SHALL BE DESIGNATED SERIES A PREFERRED, 25.0 MILLION SHARES SHALL BE DESIGNATED SERIES B PREFERRED, 70.0 MILLION SHARES WILL BE DESIGNATED SERIES C-1 PREFERRED, 50.0 MILLION SHARES WILL BE DESIGNATED SERIES C-2 PREFERRED, AND 100.0 MILLION SHARES SHALL BE DESIGNATED SERIES C-3 PREFERRED.

DESCRIPTION OF DEBENTURES 2004 DEBENTURES The following description summarizes the material terms of the 2004 Debentures. Shareholders are urged to carefully review the Debenture and Share Purchase Agreement by and among the Company and other 41

These 2004 Debentures have been issued in the form of Appendix H attached hereto. Principal, Maturity and Interest. As of June 1, 2004, the aggregate principal amount of the outstanding 2004 Debentures was $14.0 million. The Company has a right to issue additional 2004 Debentures in the aggregate principal amount of up to $3.5 million no later than June 30, 2004 or the time of conversion of the 2004 Debentures, whichever is earlier, provided, however, that such amount may be increased with prior written consent of the holders of at least 60% of the principal amount of the 2004 Debentures then held by Capital Investment II, LP, Essex Woodlands Health Ventures V, L.P., and Galen Partners III, L.P. (the "Lead 2004 Investors") Unless otherwise converted into Preferred Stock (as provided below under the caption "Automatic Conversion of 2004 Debentures") each 2004 Debenture generally becomes due and payable on July 31, 2004 (the "Maturity Date"), provided, however, that (i) the Company may extend the Maturity Date, for a period not to exceed ninety (90) days, to the extent the effectiveness of the amendment to its Certificate of Incorporation (discussed in Proposal 2) (the "Charter Amendment") is delayed due to the review of this Proxy Statement by the Commission, and (ii) the holders of 2004 Debentures holding at least percent (60%) of the aggregate principal amount of the 2004 Debentures then outstanding may extend the Maturity Date from time to time in their sole discretion.

priority as to dividends or assets, whether in liquidation or otherwise, superior to or pari passu with the Series A Preferred shares, (d) any reclassification of any outstanding shares of any class of stock of the Company into shares having any preference or priority as to dividends or assets, whether in liquidation or otherwise, superior to or pari passu with the Series A Preferred shares, (e) payment of any dividends or distributions on any securities of the Company ranking junior in priority to the Series A Preferred shares, other than dividends or distributions payable solely in Common Stock, (f) any redemption or acquisition of Company securities, (g) any merger, reorganization, consolidation or other business combination involving the Company, or sale, transfer, lease, license or other disposition of all or substantially all of the assets of the Company, (h) any liquidation, dissolution, commencement of any bankruptcy or similar proceeding, recapitalization or reorganization of the Company, (i) the consummation of any strategic alliance, licensing arrangement or other corporate partnering involving the issuance by the Company of in excess of $10.0 million in equity securities of the Company, (j) entering into any transaction, contract or commitment or the taking of any action other than at arm's length, (k) entering into or engaging in any business other than the business currently conducted or proposed to be conducted by the Company, (l) the creation of any mortgage, pledge, lien or security interest on the assets or properties of the Company (subject to certain customary exceptions), and (m) the incurrence of any indebtedness (subject to certain customary exceptions). Transfer Restrictions. The Investor Rights Agreement imposes certain restrictions on the transfer of (i) Series A Preferred Shares by the signatories to the 2004 Purchase Agreement and (ii) any shares of capital stock (together with the Series A Preferred Shares, the "Restricted Shares") held by each of Care Capital Investments II, LP, Essex Woodlands Health Ventures V, L.P., Galen Partners III, L.P. and Oracle Strategic Partners, L.P. (collectively, the "Restricted Investors"). In the event of any proposed transfer by a Restricted Investor of any Restricted Shares held by such Restricted Investor (collectively, the "Offered Shares"), such Restricted Investor must first offer the Offered Shares to the Company on the terms of the proposed sale or conveyance of such Offered Shares to a third party. In the event the Company does not exercise its right to purchase the Offered Shares on such terms, the other Restricted Investors may purchase their pro rata share of the Offered Shares on the terms proposed for transfer to such third party. Additionally, upon the sale of Offered Shares by a Restricted Investor to a third party, the remaining Restricted Investors have the right to participate in such sale on a pro rata basis. Finally, in the event the holders of at least 66 2/3% of all Restricted Shares then held by all Restricted Investors (collectively, the "Controlling Stockholders") wish to sell to any third party all Restricted Shares held by the Controlling Stockholders, then each other Restricted Investor must agree to sell all Restricted Shares held by such Restricted Investors to such third party for the same price and on the same terms as the sale by the Controlling Stockholders. Right to Board Seat. Pursuant to the terms of the Voting Agreement, dated as of February 6, 2004 (see, "Voting Agreement" below), for so long as each of the Lead 2004 Investors holds a minimum of 50% of the Series A Preferred shares initially issued to such party (or at least 50% of the shares of Common Stock issuable upon conversion of the Series A Preferred Shares), (i) each of the Lead 2004 Investors shall have the right to designate for nomination one member of the Company's Board of Directors and (ii) the Lead 2004 Investors collectively may designate one additional member of the Board (collectively, the "Designees") by consent of at least two (2) of such three (3) Lead 2004 Investors. Additionally, if so requested by a Designee in his sole discretion, such Designee shall be appointed to any Committee of the Board of Directors. So long as Galen Partners III, L.P. has the right to designate a director in its capacity as a Lead 2004 Investor, as described above, the Company will permit one observer selected by Galen Partners III, L.P. to attend all meetings of the Board of Directors of the Company, and shall provide such observer with such notice and other information with respect to such meetings as are delivered to the directors of the Company; provided, that such observer shall not be permitted to attend any meeting or portion thereof or have access to such other information if, in the judgment of the Company under advice of counsel, such observer's presence or receipt of such information would adversely affect attorney-client privilege with respect to such meeting or information.

BOARD APPROVAL OF THE CHARTER AMENDMENT APPROVAL OF CHARTER AMENDMENT BY AN INDEPENDENT COMMITTEE OF THE BOARD OF DIRECTORS Formation of the Independent Committee On October 30, 2003, the Board of Directors of the Company formed an Independent Committee of the Board (the "Independent Committee") for the purpose of evaluating the capital raising activity of the Company with the intent of seeing that efforts devoted in such regard were reasonable and unbiased and that all reasonable alternatives were considered in the process. The Independent Committee consisted of Mr. William Sumner, Chairman, and Messrs. Alan Smith and William Skelly. The Independent Committee met formally on 12 occasions during the period from its formation on October 30, 2003 through December 20, 2003. In addition, members of the Independent Committee had numerous other detailed discussions with each other, the Company's Management, and with each of the special legal counsel and the financial advisor retained by the Independent Committee, in connection with the capital raising efforts of the Company and, in particular, the 2004 Debenture Offering and the resulting Charter Amendment. In December 2003, the Independent Committee engaged Agema LLC to deliver an opinion that the terms of the 2004 Debenture Offering, including the Company's utilization of approximately $4.3 million of the proceeds of the 2004 Debenture Offering to retire $16.4 million in indebtedness owed by the Company to Watson Pharmaceuticals (as described in Proposal 1 under the caption "Certain Transactions"), was from a financial point of view fair to the Company and the Company's creditors, debenture holders, subordinated debt holders and common shareholders who are not investors in the 2004 Debentures. On January 16, 2004, Agema LLC provided its written opinion to the Independent Committee. The Agema LLC opinion is for the information and assistance of the Independent Committee in connection with the Committee's consideration of the 2004 Debenture Offering. Agema LLC's opinion is not a recommendation as to how any shareholder should vote with respect to this Proposal 2 at the Meeting. The full text of the Agema LLC opinion is attached to this Proxy Statement as Appendix D. Shareholders are encouraged to read the opinion carefully in its entirety for a description of the assumptions made, qualifications included, matters considered and limitations of the review undertaken. Information reviewed by the Independent Committee Following its formation, the Independent Committee was provided with extensive information as to the Company's capital raising activities and its efforts to locate a strategic partner or potential acquirer of the Company's business, including: - Management's presentation describing the capital raising efforts of the Company during the preceding 18 months, including a description of the approximate 36 entities that the Company had approached and the results of negotiations, if any, with such parties in an effort to form a strategic partnership and/or obtain financing. - The engagement letter dated July 30, 2002 between the Company and each of MTS Partners and CIBC providing for the joint engagement of MTS Partners and CIBC as the Company's financial advisor to assist the Company in analyzing, planning, negotiating and executing the Company's strategic and financial plan, including the identification of a strategic partner and/or a financing transaction. - Trading price information of the Company's Commons Stock for the ninety (90) days preceding the date of the non-binding term sheet between the Company and the Lead 2004 Investors relating to the 2004 Debenture Offering. During this ninety (90) day period, the Company's Common Stock traded in the range of $0.26 to $1.50 per share. - A descriptive memorandum prepared by the Company, MTS Partners and CIBC for purposes of soliciting third party sources of financing or a potential acquirer of the Company's business. The descriptive memorandum included extensive information about the Company's operations. In addition to the descriptive memorandum, the Independent Committee reviewed with Management those third 53

parties that had expressed initial interest in receiving a copy of the descriptive memorandum under cover of a confidentiality agreement. While there was initial interest expressed by a number of prospects, all of such prospects indicated an unwillingness even to entertain preliminary negotiations with the Company relating to a financing, strategic partnership or acquisition transaction. Reasons offered by such parties included, but not limited to, the absence of a strategic fit and the dilutive impact the acquisition of the Company would have on the acquirer's earnings. - The Company's Form 10-K for the fiscal year ended December 31, 2002 and the Company's quarterly reports on Form 10-Q for the quarters ended June 30, 2003 and September 30, 2003, as well as interim financial statements and other financial and operating data concerning the Company prepared by Management. - Management status updates regarding (i) the process, status and prospects of the Company's solicitation of alternative sources of financing and strategic alternatives, and (ii) the Company's operations, financial condition, future prospects, projected operations and performance and the Company's ability to meet its obligations as they come due. - Financial forecasts and projections prepared by the Company's Management with respect to the fiscal year ending December 31, 2003 and 2004. - Management's presentation describing the $2.0 million in financing remaining available as of October 30, 2003 under the Letter of Support from the Lead 2004 Investors. Management estimated that such funding would allow the Company to continue operations only through December 31, 2003. - Interim drafts of term sheets, and the final term sheet from the Lead 2004 Investors relating to the 2004 Debenture Offering. - Dilution analyses and pro forma capitalization analyses prepared by Management giving effect to the 2004 Debenture Offering. - Liquidation analyses prepared by Management. - The Fairness Opinion of Agema LLC, the financial advisor retained by the Independent Committee (as described below under the caption "Fairness Opinion"). Fairness Opinion On December 20, 2003, Agema LLC delivered its oral opinion to the Independent Committee (subsequently confirmed in writing on January 16, 2004 following review of certain documentation with respect to the 2004 Debenture Offering) that, subject to and based upon the various qualifications and assumptions described therein, the terms of the 2004 Debenture Offering were fair from a financial point of view to the Company's creditors, debenture holders, subordinated debt holders and common holders who are not investors in the 2004 Debentures. The Independent Committee retained Agema LLC to render this opinion, which is referred to in this Proxy Statement as the "Fairness Opinion." The Fairness Opinion was prepared to assist the Independent Committee in evaluating the terms of the 2004 Debenture Offering. The Independent Committee retained Agema LLC based upon Agema LLC's experience in the valuation of businesses and securities in connection with securities offerings, recapitalizations and similar transaction. Agema LLC is corporate financial advisory firm based in New York, New York that is engaged in providing financial advisory services to mid-market firms. As part of its business, Agema renders fairness opinions in connection with mergers and acquisitions, business and securities valuations, financial restructurings and private placements of debt and equity securities. No limitations were imposed by the Independent Committee upon Agema LLC with respect to the investigations made or procedures followed by it in rendering the Fairness Opinion. Agema LLC has not been requested and does not intend to update, revise or reaffirm the Fairness Opinion in connection with the 2004 Debenture Offering, including to reflect any circumstances or events that have occurred since January 16, 2004. The Fairness Opinion speaks only as of its date. Events that could affect the fairness of the 2004 Debenture Offering, from a financial point of view, to our shareholders who are not investors in the 2004 54

Debentures include adverse changes in industry market conditions and changes to Company's business, financial condition and results of operations. No relationship existed between Agema LLC and the Company, including the Company's affiliates, at the time the Fairness Opinion was prepared or delivered, none has since developed and none is mutually understood to be contemplated. In arriving at its Fairness Opinion, among other things, Agema LLC did the following: - Reviewed certain of the Company's publicly available annual and quarterly reports as filed with the Commission, including the Company's Form 10-K for the fiscal year ended December 31, 2002 and the Company's quarterly reports on Form 10-Q for the quarters ended June 30, 2003 and September 30, 2003, as well as interim financial statements and other financial and operating data concerning the Company prepared by Management; - Reviewed financial projections regarding the Company prepared by Management; - Met with members of the Independent Committee and certain members of the Company's Management regarding (i) the process, status and prospects of the Company's solicitation of alternative sources of financing and other potential strategic alternatives and (ii) the Company's operations, financial condition, future prospects, projected operations and performance and the Company's ability to meet its obligations as they come due; - Reviewed forecasts and projections prepared by the Company's Management with respect to the fiscal years ended December 31, 2003 and 2004; - Reviewed the Company's current cash position and cash operating requirements through fiscal year 2004; - Discussed with the Independent Committee and Management the prospects for the Company if the 2004 Debenture Offering was not completed; - Reviewed the historical market prices and trading volume of the Company's Common Stock; - Reviewed with the Independent Committee the financial implications of various draft terms sheets submitted by the Lead 2004 Investors to the Company and provided financial advice to the Independent Committee in response thereto; - Reviewed the final term sheet from the Lead Investor Group dated December 19, 2003, and drafts of the following documents in connection with the 2004 Debenture Offering: (i) form of Voting Agreement, (ii) form of Amended and Restated Registration Rights Agreement; (iii) Form of Third Amendment to Loan Agreement with Watson Pharmaceuticals; (iv) form of Secured Promissory Note to Watson Pharmaceuticals; (v) form of Debenture and Share Purchase Agreement; (vi) form of Debenture Conversion Agreement; (vii) form of Convertible Senior Secured Debenture; (viii) form of Confidential Private Placement Term Sheet; (ix) form of Restated Certificate of Incorporation, and (x) form of Debenture and Warrant Dilution Waiver; and - Conducted such other studies, analyses and inquiries as Agema LLC deemed appropriate. In reaching its conclusion that the terms of the 2004 Debenture Offering were fair to the Company and the Company's creditors, debenture holders, subordinated debt holders and common shareholders, Agema LLC conducted an analysis of the terms of the 2004 Debenture Offering. Such analysis included a review of the consideration to be received by the Company for the 2004 Debentures, including the liquidation preference, conversion right and participation right of the Senior A Preferred shares. Agema LLC also considered that the ownership of the Company's non-affiliated common shareholders in the Company, calculated on a fully diluted basis, following the completion of the 2004 Debenture Offering (assuming $14 million in principal amount of 2004 Debentures) would decrease from approximately 5.7% to approximately 4.0% after giving effect to the conversion of the Company's outstanding convertible securities, including the conversion of the Preferred Stock into Common Stock. Agema LLC also considered that all of 55

the Company's Outstanding Debentures would be converted into shares of Preferred Stock and the interest expenses associated with such debentures would be eliminated. Finally, Agema LLC considered the absence of any other sources of financing as well as the absence of any prospective acquirer of the Company's business and that the financing proposed to be provided under the terms of the 2004 Debenture Offering would allow the Company to avoid seeking immediate relief under applicable bankruptcy laws. Agema LLC determined that in the absence of completing the 2004 Debenture Offering, a liquidation of the Company's assets in a bankruptcy proceeding would likely result and that such liquidation would likely not yield sufficient proceeds to satisfy the Company's $21.4 million indebtedness to Watson Pharmaceuticals, thereby leaving no proceeds available for distribution to the holders of the Outstanding Debentures or the Company's common shareholders. Based on the analyses described above, Agema LLC determined that, as of the date of the Fairness Opinion, the terms of the 2004 Debenture Offering, including the consideration to be received by the Company in connection with the issuance of the 2004 Debentures, was fair, from a financial point of view to the Company and the Company's creditors, debenture holders, subordinated debt holders and holders of the Company's Common Stock who are not investors in the 2004 Debentures. In rendering the Fairness Opinion, Agema LLC relied upon and assumed, without independent verification, that the financial forecasts and projections provided to it had been reasonable and accurately prepared and reflected the best currently available estimates and judgments of the Company's Management of the Company's future financial results and conditions and that there had been no material change in the Company's assets, financial condition, business or prospects between the dates the Company's most recent financial statements were made available to Agema LLC and the date of the Fairness Opinion. Agema LLC did not independently verify the accuracy and completeness of the information supplied to it with respect to the Company and did not assume any responsibility with respect to such information, and assumed and relied upon the accuracy and completeness of all such information provided to or discussed with Agema LLC or publicly available. Agema LLC did not make any physical inspection or independent appraisal of any of the Company's properties or assets and the Fairness Opinion was necessarily based on the business, economic, market and other conditions as they existed on the date of the Fairness Opinion and could be evaluated by Agema LLC at the date of the Fairness Opinion. Under the Company's engagement letter with Agema LLC, the Company paid Agema LLC a fee of $75,000. In addition, the Company agreed, among other things, to reimburse Agema LLC for certain of its reasonable out-of-pocket expenses incurred in connection with the services provided by Agema LLC, and to indemnify and hold harmless Agema LLC and other related parties from and against various liabilities and expenses, which may include liabilities under the federal securities laws, in connection with its engagement. Consultation of the Independent Committee with its Independent Legal Counsel, Counsel for the Company and Agema LLC The Independent Committee and its independent legal counsel, Gallagher, Briody & Butler, discussed with Management and Company's counsel alternatives in the event the Company was unable to secure financing to fund operations. With the advice of its independent legal counsel, bankruptcy counsel for the Company and Agema LLC, the Independent Committee determined that in the absence of additional financing, including the restructuring of the Company's $21.4 million senior term loan indebtedness to Watson Pharmaceuticals (as described in Proposal 1 under the caption "Certain Transactions"), the Company likely would be forced to seek protection under applicable bankruptcy laws as early as January 2004. Based on the capital structure of the Company, including the significant indebtedness outstanding under the $21.4 million senior term loan with Watson Pharmaceuticals and the Outstanding Debentures, all of which were in default, the Independent Committee determined that a liquidation of the Company's assets in a bankruptcy proceeding would likely not yield any proceeds to the holders of the Outstanding Debentures or the holders of Common Stock and that a financing outside of bankruptcy presented the best alternative to preserve and potentially enhance shareholder value. 56

Throughout the negotiation of the term sheet with the Lead 2004 Investors relating to the 2004 Debenture Offering, including as part of the 12 formal meetings held by the Independent Committee during such time, the Independent Committee considered the substantial dilution to the ownership interest in the Company of the Company's public, non-affiliated shareholders as a group given the liquidation preference, conversion right and participation right proposed by the Lead 2004 Investors for the Series A Shares. As discussed above under the caption "Background", throughout the process of negotiating the term sheet for the 2004 Debenture Offering, the Independent Committee instructed Senior Management and Company legal counsel to continue to negotiate for terms as favorable as possible to the Company relating to the liquidation, conversion and participation rights of the Series A Shares in an effort to reduce the dilution to the Company's public, non-affiliated shareholders. As also described under the caption "Background", the efforts of the Independent Committee and Senior Management resulted in a final term sheet containing more favorable terms to the Company than those initially proposed by the Lead 2004 Investors, which mitigated to some extent the dilution to the Company's common shareholders. The dilutive impact of the 2004 Debenture Offering, among other negative factors, was considered by the Independent Committee in its determination to approve the 2002 Debenture Offering, as described below under the caption "Additional Factors Considered by the Independent Committee." Additional Factors Considered by the Independent Committee The Independent Committee also reviewed with Management the Company's default under its interest payment obligations under the $21.4 million term loan with Watson Pharmaceuticals (the "Watson Term Loan") and the 1998-2002 Debentures. All of such indebtedness is secured by a lien on all the Company's and its subsidiaries' assets. The Independent Committee considered that the completion of the 2004 Debenture Offering would provide the Company with the approximate $4.3 million in proceeds required to restructure Watson Term Loan and obtain Watson's forgiveness of approximately $16.4 million of such indebtedness, resulting in new principal balance under the Watson Term Loan of $5.0 million. Such restructuring would also allow for the conveyance of the amended $5.0 million Watson note to the investors in the 2004 Debentures in satisfaction of a condition to the completion of the 2004 Debenture Offering. (See the description of the Watson Term Loan restructuring contained in Proposal 1 under the caption "Certain Transactions".) In addition, the Independent Committee considered that in the event of the completion of the 2004 Debenture Offering and the receipt of shareholder approval of the Charter Amendment, all of the Company's Outstanding Debentures, including the 2004 Debentures, would be converted into shares of Preferred Stock, thereby reducing the Company's outstanding indebtedness by approximately $102 million. In addition to the foregoing, in determining to authorize the 2004 Debenture Offering, the Independent Committee also considered the following factors: - The $0.70 average closing price for the Company's Common Stock for the ninety (90) days prior to the December 19, 2003, the date of the final term sheet between the Company, the Lead 2004 Investors and the holders of the Company's Outstanding Debentures describing the terms of the 2004 Debenture Offering; - The restricted nature of the securities being issued to the investors pursuant to the 2004 Debenture Offering, including the restricted nature of the securities issued upon conversion of the 2004 Debentures and the Preferred Stock; - The waiver by the holders of the Outstanding Debentures and Watson Pharmaceuticals of their respective anti-dilution rights contained in the Outstanding Debentures and the Common Stock Purchase Warrant previously issued to Watson; - The fact that each of Care Capital, Essex and Galen is an affiliate of the Company and this relationship between the Company and such entities further limits their ability to resell the shares of Common Stock underlying the Preferred Stock received upon the conversion of their respective Outstanding Debentures; 57

- The Company's September 30, 2003 financial statements, including the balance sheet included as part of the September 30, 2003 Form 10-Q; - The insolvent condition of the Company in both the sense that the Company's liabilities greatly exceeded the Company's assets and the fact that the Company had not been able to satisfy its obligations as they currently matured, including, without limitation, the Company's payment obligations under the Watson Term Loan and the Outstanding Debentures; - Various conversations with Management and documentation supplied by the Company's Chief Financial Officer with respect to the approximate 36 parties that were unsuccessfully approached by the Company and its representatives for financing; - The absence of other available sources of financing; - The impact a bankruptcy filing by the Company would have on the public, non-affiliated shareholders of the Company and that a bankruptcy filing was likely in the absence of completing the 2004 Debenture Offering; - Management's efforts to pursue a merger or sale transaction, all of which efforts were unsuccessful; and - The fact that the Company was in default under the Watson Term Loan and the Outstanding Debentures. The Independent Committee believed that each of the above factors generally supported its determination. The Independent Committee did, however, consider the potential adverse effects of the following factors: - The substantial dilution to the Company's public, non-affiliated shareholders in their ownership interest in the Company; - The five (5) times liquidation preference of the Series A Shares issuable upon conversion of the 2004 Debentures and the right of each Series A Share to convert to into five common shares; - The right of the holders of the Series A Shares to participate with the holders of the Company's Common Stock in proportion to the number of shares held by such parties on an as-converted basis, calculated such that each of the Series A Shares shall be deemed to be convertible into only 30% of the shares of Common Stock into which it is otherwise then convertible; and - That the Board of Directors would be fixed at seven members, four of whom would be appointed by the Lead 2004 Investors. The foregoing represents all material factors considered by the Independent Committee in its evaluation of the 2004 Debenture Offering. In view of the variety of factors considered in connection with the 2004 Debenture Offering, the Independent Committee did not find it practical to, and did not quantify or otherwise assign relative weights to specific factors considered in reaching its decision. Approval by and Recommendation of the Independent Committee On December 20, 2003, the Independent Committee delivered a unanimous resolution to the Board of Directors of the Company in which it concluded that the 2004 Debenture Offering was fair from a financial point of view to the creditors and public stockholders of the Company, other than the investors in the 2004 Debentures, and that the capital raising efforts of the Company had been reasonable and unbiased and that all reasonable alternatives were considered in the process. Accordingly, the Independent Committee unanimously recommended to the Board that the Board approve and authorize the 2004 Debenture Offering (with abstentions by appropriate Board members as described below under the caption "Approval by the Board of Directors"). A copy of the resolutions of the Independent Committee is attached to this Proxy Statement as Appendix E. On June 5, 2004, the Independent Committee unanimously adopted a resolution approving the terms of the 2004 Purchase Agreement Amendment providing for (i) an increase in the principal amount of the 2004 58

Debentures issuable under the 2004 Purchase Agreement from $14.0 million to $17.5 million, and (ii) an extension of the date for issuance of additional 2004 Debentures from June 5, 2004 to June 30, 2004. Approval by the Board of Directors At a meeting of the Board of Directors held on January 20, 2004, the Board of Directors considered the recommendation of the Independent Committee, including the Fairness Opinion delivered by Agema LLC and, after concluding that the terms of the 2004 Debenture Offering, including the restructuring of the Watson Term Loan, represented fair value and that the terms and provisions of the 2004 Debenture Offering were reasonable and that the completion of the 2004 Debenture Offering would permit the Company to satisfy its current liabilities, to restructure the Watson Term Loan, to convert the Company's Outstanding Debentures into Preferred Stock, and allow the Company to continue operations in an effort to enhance shareholder value, the Board of Directors unanimously approved the terms of the 2004 Debenture Offering. Messrs. Wesson, Conjeevaram, Shroff, Karabelas and Thangaraj, as designees of Care Capital, Essex and Galen, the Lead 2004 Investors, abstained from the vote. On June 6, 2004, the Board of Directors considered the resolution of the Independent Committee relating to the 2004 Purchase Agreement Amendment and unanimously approved the terms of the 2004 Purchase Agreement Amendment. EFFECT OF THE CHARTER AMENDMENT IN GENERAL The Charter Amendment will provide for an increase in the number of authorized shares of the Company's capital stock from 80.0 million to 940.0 million, consisting of 650.0 million shares of Common Stock and 290.0 million shares of Preferred Stock. The authorization of the Preferred Stock designates 45.0 million shares as Series A Preferred, 25.0 million shares of Series B Preferred, 70.0 million shares as Series C-1 Preferred, 50.0 million shares as Series C-2 Preferred and 100.0 million as Series C-3 Preferred. The increase in the Company's authorized capital stock will provide sufficient authorized shares to permit the following: - The conversion of the 2004 Debentures into Series A Preferred shares (including additional 2004 Debentures in the principal amount of up to $3.5 million that may be issued by the Company prior to June 30, 2004 pursuant to the 2004 Purchase Agreement Amendment); - The conversion of the 2002 Debentures issued in calendar year 2003 into Series B Preferred shares; - The conversion of the 1998 Debenture, 1999 Debentures and 2002 Debentures in Series C-1 Preferred, Series C-2 Preferred and Series C-3 Preferred shares, respectively; - The conversion of the Series A Preferred, Series B Preferred and Series C Preferred into Common Stock in accordance with their terms; - The exercise of stock option agreements granted under the Company's 1998 Stock Option Plan, as amended (as described in Proposal 5 of this Proxy Statement) to the extent of the increase in the number of shares of Common Stock available under the Plan from 8.1 million to 20.0 million. As more particularly described in Proposal 5, the increase in the shares available under the 1998 Stock Option Plan, as amended, will allow the Company to satisfy commitments to issue stock options to its officers and employees aggregating 13,175,145 shares; - The exercise of the Company's outstanding Common Stock purchase warrants; - The issuance of Common Stock in satisfaction of quarterly interest payments under the $5.0 million Amended and Restated Watson Note (see "Interests of Investors in the 2004 Debenture Offering" below); and 59

- Assure an adequate supply of authorized, unissued and unreserved shares available for general corporate needs and to provide the Board the flexibility to issue Common Stock in connection with acquisitions, merger transactions or financings without the expense and delay incidental to obtaining shareholder approval of any amendment to the Company's Charter at the time of such action, except as may be required for a particular issuance by applicable law or by the rules of any stock exchange on which the Company's securities may then be listed. The additional authorized shares may be used for such purposes as raising additional capital or financing an acquisition or business combination. The Company believes that the number of shares remaining available after giving affect to the Company's currently outstanding convertible securities, as well as the Preferred Stock proposed to be issued upon the conversion of the Company's Outstanding Debentures, will provide the Company with sufficient authorized and unreserved shares to meet its future requirements. The additional shares of Common Stock for which authorization is sought under the Charter Amendment would be identical to the shares of Common Stock of the Company now authorized. Holders of Common Stock do not have preemptive rights to subscribe for additional securities which may be issued by the Company. As of the date of the printing of this Proxy Statement, other than the satisfaction of the Company's obligations under the convertible securities described above, the Company has no commitments or agreements with any third party provided for, or any current intention or proposal contemplating, the issuance or reservation of any additional shares of Preferred Stock or Common Stock proposed to be authorized by the Charter Amendments. Such shares would, however, be available for issuance without further action by the Company's shareholders, unless required by applicable law. If the Charter Amendment is approved by shareholders, the 2004 Debentures will convert automatically into Series A Preferred shares. In addition, 1998-2002 Debentures will convert automatically into Junior Preferred Shares. After giving effect to the conversion of the Company's Outstanding Debentures into Preferred Stock, the Series A Preferred shares will be convertible into an aggregate of approximately 136.8 million shares of the Company's Common Stock (assuming $17.5 million in outstanding principal amount of the 2004 Debentures), representing approximately 35.4% of the Company's Common Stock on a fully diluted basis and the Junior Preferred Shares will be convertible into an aggregate of approximately 195 million shares of the Company's Common Stock, representing approximately 49.5% of the Company's Common Stock on a fully-diluted basis. OTHER EFFECTS OF CHARTER AMENDMENT Galen Control Assuming receipt of shareholder approval of this Proposal 2, Galen would control approximately 42.0% of the Company's voting securities (43.6% after giving affect to the conversion of all of the Company's outstanding convertible securities). In addition, Bruce Wesson, a nominee for Director, is the designee of Galen. In accordance with the terms of the Voting Agreement dated as of February 6, 2004 between the Company and the holders of the Outstanding Debentures, the Company has agreed to nominate and appoint to the Board of Directors, subject to shareholder approval, one designee of Galen and one collective designee of each of Care Capital, Essex and Galen, for so long as Galen holds a minimum of 50% of the Series A Preferred shares initially issued to Galen (or at least 50% of the shares of Common Stock issuable upon conversion of such Series A Preferred shares). 60

Dilution of Existing Shareholders' Investment The completion of the 2004 Debenture Offering, including the issuance of the Series A Shares upon conversion of the 2004 Debentures, will cause substantial dilution in the ownership interest of the Company's public, non-affiliated shareholders. The following table provides the ownership percentages in the Company held by the 2004 Debentureholders as a group, the holders of the 1998-2002 Debentures as a group and the Company's public, non-affiliated shareholders as a group, both before and after giving effect to the completion of the 2004 Debenture Offering (calculated on a fully-diluted basis):

FULLY DILUTED OWNERSHIP PERCENTAGE IN THE COMPANY AFTER THE COMPLETION OF THE 2004 DEBENTURE OFFERING --------------------------------------- FULLY DILUTED OWNERSHIP PERCENTAGE ASSUMES ASSUMES IN THE COMPANY BEFORE THE COMPLETION $14.0 MILLION $17.5 MILLION SECURITY HOLDERS OF THE 2004 DEBENTURE OFFERING IN 2004 DEBENTURES IN 2004 DEBENTURES - ---------------- ------------------------------------ ------------------ ------------------ - - 2004 Debentureholders as a Group... -- 30.5% 35.4% - - 1998-2002 Debentureholders as a Group.............................. 76.2% 53.3% 49.5% - - Public, Non-Affiliated Shareholders as a Group......................... 5.7% 4.0% 3.7%
The issuance of the Preferred Stock as well as the issuance of Common Stock upon conversion of the Preferred Stock could have an adverse affect on the potential realizable value of a shareholder's investment. In the absence of a proportionate increase in the Company's earnings and book value, an increase in the aggregate number of outstanding shares of the Company caused by the issuance of additional shares, such as the Preferred Stock or the Common Stock underlying the Preferred Stock, would dilute the earnings per share and book value per share of all outstanding shares of the Company's Common Stock. If such factors were reflected in the price per share of the Common Stock, the potential realizable value of a shareholder's investment could be adversely affected. In addition, the anti-dilution provisions contained in the Series A Preferred and Junior Preferred Shares could further dilute the ownership interest of existing shareholders. Latent Anti-Takeover Effect As of June 1, 2004, the Company had issued an outstanding 21,716,025 shares of its Common Stock. Assuming the receipt of shareholder approval of this Proposal 2 and the issuance by the Company of $17.5 million in principal amount of 2004 Debentures under the 2004 Purchase Agreement, on the Charter Amendment Filing Date the Company will issue approximately 222.3 million shares of Preferred Stock in consideration of the conversion of the Outstanding Debentures. After giving effect to the issuance of such Preferred Stock, and considering the Company's outstanding Common Stock purchase options and warrants as of June 1, 2004 (assuming the receipt of shareholder approval to the amendment to the 1998 Stock Option Plan as provided in Proposal 5 of this Proxy Statement), the Company will have issued and outstanding securities convertible into an aggregate of approximately 368.3 million shares of its Common Stock. If all such convertible securities were exercised and/or converted, the Company would have issued and outstanding approximately 390.0 million shares of its Common Stock. Assuming shareholder approval of this Proposal 2, after giving effect to such convertible securities, the Company would have approximately 67.7 million shares of Preferred Stock and 260.0 million shares of Common Stock unreserved and available for issuance. The increase in the number of shares of capital stock authorized for issuance could, under certain circumstances, be construed as having an anti-takeover effect. For example, in the event a person seeks to effect a change in the composition of the Board of Directors of the Company or contemplates a tender offer or other transaction for the combination of the Company with another company, it may be possible for the Company to impede the attempt by issuing additional shares of capital stock, thereby diluting the voting power of the other outstanding shares and increasing the potential cost to acquire control of the Company. The proposed Charter amendment may also have the effect of permitting the Company's current management, including our Board of Directors, to retain its position indefinitely and place it in a better position to resist 61

changes that shareholders may wish to make if they are dissatisfied with the conduct of the Company's business. The Company's Charter does not provide for cumulative voting and the Charter Amendment does not include cumulative voting rights. As a result, in order to ensure representation on the Board, a shareholder must control the votes of a majority of the voting securities present and voting at a shareholders' meeting at which a quorum is present. The lack of cumulative voting requires an entity seeking a takeover to acquire a substantially greater number of shares to ensure representation on the Board than would otherwise be necessary were cumulative voting available. Certain provisions of the Company's By-laws could also have the effect of deterring takeover attempts because of procedural provisions contained therein. The By-laws provide that special shareholder meetings may be called by the President or Secretary of the Company, or by resolution of the Board of Directors. The Company's By-laws further provide that the Board of Directors has the authority to postpone any previously scheduled annual or special meeting of shareholders upon public notice given in accordance with the By-laws. In addition, except as otherwise required by law, the By-laws limit the business that may be transacted at a special meeting of shareholders to the matters specified in the notice of such special meeting. The Board of Directors did not propose the Charter Amendment in response to any effort known to the Board of Directors to accumulate Common Stock or to obtain control of the Company by means of a merger, tender offer or solicitation in opposition to management. In addition, this Proposal 2 is not part of any plan by Management to recommend a series of similar amendments to the Board of Directors and the shareholders. Finally, the Board of Directors does not currently contemplate recommending the adoption of any other amendments to the Company's Charter that could be construed as affecting the ability of third parties to take over or change the control of the Company. Satisfaction of the Company's Obligations under the 2004 Debenture Purchase Agreement Shareholder approval of this Proposal 2 will allow the Company to satisfy its contractual obligations under the 2004 Purchase Agreement. Specifically, the 2004 Purchase Agreement obligates the Company to obtain shareholder approval to this Proposal 2 in order to provide for the automatic conversion of the 2004 Debentures into Series A Preferred shares and the automatic conversion of the 1998-2002 Debentures into Junior Preferred Shares. The 2004 Purchase Agreement further provides that in the event the Company fails to obtain shareholder approval to this Proposal 2 on or prior to July 31, 2004 (subject to extension for up to ninety (90) days under certain circumstances), the rate of interest accruing under the 2004 Debentures will increase from 1.62% to 15%. The Company's failure to obtain shareholder approval to this Proposal 2 will render the Company unable to issue its Preferred Stock in full satisfaction of the Company's Outstanding Debentures. In such event, the Company would be in default under the terms of the Outstanding Debentures as well as the Amended and Restated Watson Note allowing the holders of the Outstanding Debentures and the Watson Note Purchasers to accelerate the maturity of such indebtedness. The occurrence of these events would have a material adverse affect on the Company's financial condition. Availability of Shares for Future Issuances The approval of this Proposal 2 will make available shares of the Company's Preferred Stock and Common Stock for issuance in equity financings and also might enable the Company to pursue acquisitions or enter into transactions which the Board believes provides the potential for growth and profit. If additional authorized shares are available, transactions dependent on the issuance of additional shares will be less likely to be undermined by delays and uncertainties occasioned by the need to obtain shareholder authorization prior to consummation of such transactions. The ability to issue shares as deemed in the Company's best interest by the Board, would also permit the Company to avoid the expenses which are incurred in holding certain shareholder's meetings. Pursuant to an Investor Rights Agreement dated as of February 6, 2004, between the Company and the holders of the Outstanding Debentures, except for the Preferred Stock issuable upon conversion of the 62

Outstanding Debentures, the Company is precluded from issuing any additional shares of Preferred Stock in the absence of the written consent of the holders of 60% of the Series A Preferred shares. INTERESTS OF INVESTORS IN THE 2004 DEBENTURE OFFERING As of June 1, 2004, each of Care Capital, Essex and Galen (the "Lead 2004 Investors") had designees serving on the Board of Directors. Specifically, each of Messrs. Wesson, Conjeevaram and Shroff are designees of Galen. Messrs. Karabelas and Thangaraj are the designees of Care Capital and Essex, respectively. In accordance with the terms of the Voting Agreement dated as of February 6, 2004, by and among the Company and the holders of the Outstanding Debentures, the Company has agreed to nominate to the Board one designee of each of Galen, Care Capital and Essex and one collective designee of such parties. See Proposal 1 under the caption "Agreements Governing Appointment of Directors" for a more detailed description of the Voting Agreement. Pursuant to the Voting Agreement, effective as of the Meeting date, Messrs. Wesson, Karabelas and Thangaraj will be the Board designees of Galen, Care Capital and Essex, respectively. The collective designee to the Board of the Lead 2004 Investors has not yet been identified and designated. As part of the completion of the 2004 Debenture Offering, the Lead 2004 Investors invested an aggregate of $11,970,902 in the 2004 Debentures. Additionally, the Lead 2004 Investors own an aggregate of $68,996,368 in principal amount of the 1998-2002 Debentures. Assuming the receipt of shareholders approval of this Proposal 2, and after giving effect to the conversion of the Outstanding Debentures issued and outstanding as of June 1, 2004 into Preferred Stock, Galen, Care Capital and Essex will control 45.5%, 14.7% and 17.1% of the Company's outstanding voting securities (or approximately 46.9%, 13.3% and 15.5%, respectively, after giving effect to the conversion of all of the Company's outstanding Common Stock Purchase options and warrants). The Company was a party to a certain loan agreement with Watson Pharmaceuticals pursuant to which Watson made term loans to the Company (the "Watson Term Loan Agreement") in the aggregate principal amount of $21.4 million as evidenced by two promissory notes (the "Watson Notes"). It was a condition to the completion of the 2004 Debenture Offering that simultaneous with the closing of the 2004 Purchase Agreement, the Company shall have paid Watson the sum of approximately $4.3 million (which amount was funded from the proceeds of the 2004 Debenture Offering) and conveyed to Watson certain Company assets in consideration for Watson's forgiveness of approximately $16.4 million of indebtedness under the Watson Notes. A part of such transaction, the Watson Notes were amended to extend the maturity date of such notes from March 31, 2006 to June 30, 2007, to provide for satisfaction of future interest payments under the Watson Notes in the form of the Company's Common Stock, to reduce the principal amount of the Watson Notes from $21.4 million to $5.0 million, and to provide for the forbearance from the exercise of rights and remedies upon the occurrence of certain events of default under the Watson Notes (the Watson Notes as so amended, the "Amended and Restated Watson Note"). Simultaneous with the issuance of the Amended and Restated Watson Note, each of the Lead 2004 Investors and the other investors in the 2004 Debentures as of February 10, 2004 (collectively, the "Watson Note Purchasers") purchased the Amended and Restated Note from Watson in consideration for a payment to Watson of $1.0 million. In addition to Watson's forgiveness of approximately $16.4 million under the Watson Notes, as additional consideration for the Company's payment to Watson of approximately $4.3 million and the Company's conveyance of certain Company assets, all current supply agreements between the Company and Watson were cancelled and Watson waived the dilution protections contained in the Common Stock purchase warrant dated December 20, 2002 exercisable for approximately 10.7 million shares of the Company's Common Stock previously issued by the Company to Watson, to the extent such dilution protections were triggered by the transactions provided in the 2004 Debenture Offering. The Amended and Restated Watson Note in the principal amount of $5.0 million as purchased by the Watson Note Purchasers is secured by a first lien on all of the Company's and its subsidiaries' assets, senior to the lien securing the Outstanding Debentures and all other Company indebtedness, carries a floating rate of interest equal to the prime rate plus 4.5% and matures on June 30, 2007. 63

The principal amount of the $5.0 million Amended and Restated Watson Note was allocated among the Watson Note Purchasers based on the quotient of each Watson Note Purchaser's investment in the 2004 Debentures, divided by the approximate $12.3 million in principal amount of the 2004 Debentures issued on February 10, 2004. As a result, of the $5.0 million principal balance of the Amended and Restated Watson Note, approximately $1,754,494, $1,352,051 and $1,754,454 is owed by the Company to Galen and its affiliates, Care Capital and Essex, respectively (representing approximately 35.1%, 27% and $35.1% respectively, of the principal amount of the Amended and Restated Watson Note). VOTE REQUIRED The affirmative vote of the holders of a majority of the Company's outstanding voting securities is required to approve this Proposal 2 to authorize the Charter Amendment. Pursuant to the terms of the Voting Agreement executed in connection with the 2004 Debenture Offering, (See "Additional Agreements with Holders of Debentures/Preferred Stock -- Voting Agreement" above) the Voting Agreement Parties have agreed to vote all of their respective voting securities of the Company in favor of this Proposal 2. The aggregate voting securities held by the Voting Agreement Parties is approximately 51,653,363 shares, representing approximately 78.6% of the voting rights under the Company's outstanding voting securities. Given the aggregate voting securities held by the Voting Agreement Parties, the approval of this Proposal 2 by a majority of the Company's voting securities is assured. If this Proposal 2 is adopted, the Company's Charter will be amended and restated in the form of Appendix C attached to this Proxy Statement. DISSENTING SHAREHOLDERS' RIGHT OF APPRAISAL Pursuant to Section 806 of the New York Business Corporation Law ("NYBCL"), holders of the Company's Common Stock who follow the procedures set forth in Section 623 of the NYBCL (the "Appraisal Statute") will be entitled to have their Common Stock appraised by a New York State Court and to receive payment of the "fair value" of such shares as determined by such court. The Appraisal Statue is reprinted in its entirety as Appendix B to this Proxy Statement. While the following discussion summarizes all material terms of the law pertaining to appraisal rights under the NYBCL, it is qualified in its entirety by the full text of the Appraisal Statute. Any shareholder who wishes to exercise such appraisal rights or to preserve the right to do so, should review the following discussion and Appendix B carefully because failure to timely and properly comply with the procedures specified will result in the loss of dissenters' appraisal rights under the NYBCL. All references in the Appraisal Statute and in this summary to a "shareholder" are to the recordholder of the Company's Common Stock on the Record Date. A person having a beneficial interest in shares of the Company's Common Stock that are held of record by another person such as a broker or nominee must act promptly to cause the record holder to follow the steps summarized below properly and in a timely manner to perfect whatever appraisal rights the beneficial owner may have. A shareholder wishing to exercise appraisal rights must (i) deliver to the Company, prior to or at the Meeting but before the vote is taken on this Proposal 2, a written objection to the proposed amendment to the Company's Charter as provided in this Proposal 2 (the "Notice of Election"), which must include a notice of his election to dissent, the shareholder's name, residence address, the number of shares as to which the shareholder dissents and a demand for payment of the fair value of such shares (which Notice of Election must be in addition to and separate from any proxy or vote against the amendment to the Company's Charter contemplated by this Proposal 2 (the "Charter Amendment")) and (ii) not vote for approval and adoption of the Charter Amendment. BECAUSE A PROXY WHICH DOES NOT CONTAIN VOTING INSTRUCTIONS WILL, UNLESS REVOKED, BE VOTED FOR APPROVAL OF THE CHARTER AMENDMENT, A SHAREHOLDER WHO VOTES BY PROXY AND WHO WISHES TO EXERCISE APPRAISAL RIGHTS MUST (a) VOTE AGAINST APPROVAL AND ADOPTION OF THE CHARTER AMENDMENT OR (b) ABSTAIN FROM VOTING ON THE CHARTER AMENDMENT.Neither a vote against the Charter Amendment, in person or by proxy, nor a Proxy directing such vote for an abstention, will in and of itself constitute a written objection to the Charter 64

Amendment under the Appraisal Statute (shareholders who timely file such Notice of Election and who do not vote in favor of the Charter Amendment are referred to as "Dissenting Shareholders"). A shareholder may not dissent as to less than all of the shares, as to which such shareholder has a right to dissent, held by such shareholder of record and owned beneficially. A nominee or fiduciary may not dissent on behalf of any beneficial owner as to less than all of the shares held of record by such nominee or fiduciary on behalf of such owner and as to which such nominee or fiduciary has a right to dissent. All Notices of Election should be addressed to Halsey Drug Co., Inc., 616 N. North Court, Suite 120, Palatine, Illinois 60067, Attention: Mr. Peter Clemens, Senior Vice President. Within 10 days after the date on which shareholders approve and adopt the Charter Amendment, the Company must send written notice by registered mail to each Dissenting Shareholder to such effect (the "Dissenting Shares"). At the time of the filing of the amended Charter with the Department of State of the State of New York (the "Effective Time"), each Dissenting Shareholder will cease to have any rights of a shareholder of the Company except the right to be paid the fair value of his shares and rights under the Appraisal Statute. A Notice of Election may be withdrawn by a Dissenting Shareholder prior to his acceptance in writing of an offer made by the Company to pay the value of such Dissenting Shares, except that a Notice of Election may not be withdrawn later than 60 days following the Effective Time unless the Company fails to make a timely offer to pay such value, in which case such Dissenting Shareholder shall have 60 days from the date an offer is made to withdraw his election. In either event, after such time, a Notice of Election may not be withdrawn without the written consent of the Company. In order to be effective, withdrawal of a Notice of Election must be accompanied by a return to the Company of any advance payment made to the Dissenting Shareholder by the Company as described below. Upon filing the Notice of Election, or within one month thereafter, Dissenting Shareholders must submit the certificates representing their Common Stock to the Company, attention: Peter Clemens, Senior Vice President, at the address set forth above or to the Company's transfer agent, Continental Stock Transfer and Trust Company, 2 Broadway, 19th Floor, New York, New York 10004 and there will be noted thereon that a Notice of Election has been filed and the certificates will be returned to the Dissenting Shareholders. Any Dissenting Shareholders who fail to submit such certificates for such notation will, at the option of the Company exercised by written notice to such Dissenting Shareholders within 45 days of the date of filing of such Notice of Election, lose their appraisal rights unless a court, for good cause shown, shall otherwise direct. Within 15 days after the expiration of the period within which shareholders may file their Notice of Election, or within 15 days after the Effective Time, whichever is later (but in no case later than 90 days after the shareholders' vote to approve and adopt the Charter Amendment), the Company must make a written offer to pay for the Dissenting Shares held by such Dissenting Shareholder at a price which the Company considers to be their fair value. This offer will be accompanied by a statement setting forth the aggregate number of shares, which will be at the same price for all Dissenting Shares, with respect to which Notices of Election to dissent have been received and the aggregate number of holders of such shares. If the Effective Time has occurred at the time the offer is made, the offer will be accompanied by (i) advance payment to each Dissenting Shareholder who has submitted certificates for notation thereon of the election to dissent of an amount equal to 80% of such offer or (ii) as to each Dissenting Shareholder who has not yet submitted certificates for notation thereon of the election to dissent, a statement that advance payment of an amount equal to 80% of the amount of such offer will be made by the Company promptly upon submission of certificates. If the Effective Time of the Charter Amendment has not occurred at the time of the making of such offer, such advance payment or statement as to advance payment will be sent to each Dissenting Shareholder entitled thereto upon the Effective Time. Acceptance of such advance payment by a Dissenting Shareholder will not constitute a waiver of dissenter's rights. If the Charter Amendment is not effective within 90 days after approval of the Charter Amendment by shareholders, such offer will be conditioned upon consummation of the Charter Amendment. 65

If within 30 days after making such offer, the Company and any Dissenting Shareholder agree on the price to be paid for such Dissenting Shareholder's Dissenting Shares, the Company will pay the agreed price to such holder within 60 days after the later of the date such offer was made or the Effective Time, upon surrender of certificates representing such holder's Common Stock. If the Company fails to make an offer within the 15-day period described above, or if it makes an offer and any Dissenting Shareholder fails to agree within 30 days of the making of such offer, the Company must, within 20 days thereafter institute a special proceeding in an appropriate court to determine the rights of Dissenting Shareholders and to fix the fair value of the shares. If the Company does not institute such a proceeding within such 20-day period, any Dissenting Shareholder may, within 30 days after such 20-day period expires, institute a proceeding for the same purpose. If such proceeding is not instituted by any Dissenting Shareholder within such 30-day period, all dissenters' rights will be extinguished unless the New York Supreme Court, for good cause shown, otherwise directs. All Dissenting Shareholders, other than those who agree with the Company as to the price to be paid for their shares, will be made parties to such proceeding With respect to Dissenting Shareholders entitled to payment, the court will proceed to fix the value of the Company's Common Stock which will be the fair value as of the close of business on the day prior to the Meeting. In fixing the fair value of the shares of the Company's Common Stock, the court will consider the nature of the Charter Amendment and the effects on the Company and its shareholders, the concepts and methods then customary in relevant securities and financial markets for determining fair value of shares of a corporation engaging in a similar transaction under comparable circumstances and all other relevant factors. The court will determine the fair value of such shares without a jury and without referral to an appraiser or referee. The final order by the court will include an allowance for interest (unless the court finds the refusal of any Dissenting Shareholder to accept the offer of the Company thereof as arbitrary, vexatious, or otherwise not in good faith) of such rate as the court finds to be equitable, accruing from the Effective Time to the date of payment. Each party in the appraisal proceeding will bear its own costs and expenses, including the fees of counsel and any experts employed by it. The court may, however, in its discretion, assess any of the costs, fees and expenses incurred by the Company against Dissenting Shareholders (including those who withdraw their Notice of Election) if the court finds that their refusal to accept the offer of the Company was arbitrary, vexatious or otherwise not in good faith. Similarly, the costs, fees and expenses incurred by Dissenting Shareholders may be assessed by the court in its discretion, against the Company if the fair value of the shares as determined by the court materially exceeds the amount which the Company offered to pay, the Company failed to follow certain procedures of the Appraisal Statute or the Company's manner of compliance with the Appraisal Statue was arbitrary, vexatious or not otherwise in good faith. Within 60 days after the final determination of the proceeding, the Company will pay to each Dissenting Shareholder the amount found in such proceeding to be due such shareholder, upon surrender of certificates of the Company's Common Stock. Any shareholder who duly demands, prior to the Meeting, an appraisal in compliance with the Appraisal Statute will not, after the Effective Time, be entitled to vote the shares subject to such demand for any purpose or to the payment of dividends or other distributions on those shares, except dividends or other distributions payable to shareholders of record as of a date prior to the Effective Time. Failure to follow the steps required by the Appraisal Statute for perfecting appraisal rights may result in the loss of such rights. IN VIEW OF THE COMPLEXITY OF THE PROVISIONS OF THE APPRAISAL STATUTE, SHAREHOLDERS WHO ARE CONSIDERING DISSENTING FROM THE CHARTER AMENDMENT SHOULD CONSULT THEIR LEGAL ADVISORS. 66

PROPOSAL 3 AMENDMENT TO CERTIFICATE OF INCORPORATION TO CHANGE THE NAME OF THE COMPANY The Board of Directors of the Company has unanimously adopted a resolution and recommends to the shareholders for their adoption and approval an amendment to the Company's Restated Certificate of Incorporation to change the name of the Company from "Halsey Drug Co., Inc." to "Acura Pharmaceuticals, Inc.". Purpose of Proposed Name Change. Following the restructuring of the Company's operations, including the closure of the Company's finished dosage manufacturing and packaging facilities in Congers, New York and the divestment of the assets used in the operation of such facilities, the Company has discontinued the manufacture and sale of finished dosage generic products and transferred the proprietary research and development operations previously conducted at its Congers locations to the Company's facility located in Culver, Indiana. At the Culver, Indiana facility, the Company will focus its efforts on the research, development, scale up and manufacture of opioid active pharmaceutical ingredients ("APIs") and opioid containing finished dosage form products utilizing its proprietary opioid API synthesis technologies and finished dosage abuse deterrent formulation technology. As a consequence of the restructuring of operations, the use of the "Halsey Drug Co., Inc." name will no longer serve the Company's interest because of its association with its previous line of business and the possible confusion about the Company's identity, which could result. Moreover, a new name better signifies that the Company has adopted a business strategy focused primarily on developing and commercializing proprietary pharmaceutical products directed at deterring potential abuse and misuse of orally administered prescription opioid containing products. Accordingly, the Board believes that, as the Company begins to reach new audiences, the new "Acura Pharmaceuticals, Inc." name of the Company is more likely to have a greater intangible value, and a greater name recognition value in the future than its current name. Restated Certificate of Incorporation. If approved, the FIRST paragraph of the Company's Amended Charter would be restated in its entirety as follows: "FIRST: The name of the Corporation shall be ACURA PHARMACEUTICALS, INC." The form of the Amended Charter is included as Appendix C hereto. If approved, the Amended Charter will become effective upon filing of same with the Department of State of the State of New York. Effect of Name Change on Shareholders. The Company's shareholders will not be required to submit their stock certificates for exchange. Stock certificates bearing the "Halsey Drug Co., Inc." name will continue to be valid certificates and will evidence ownership of the same number of shares of the Company's capital stock after the name change as stated in Amended Charter. Following the effective date of Amended Charter, all new stock certificates issued by the Company will be printed using the Company's new name. New Trading Symbol. Upon the approval of the Amended Charter the Company will apply for a new trading symbol more readily identifiable with the new Company name. VOTE REQUIRED The affirmative vote of the holders of a majority of the Company's voting securities is required for the approval of the Amended Charter. 67

RECOMMENDATION OF THE BOARD OF DIRECTORS The Board of Directors recommends a vote FOR the approval of the change of the Company's name, as provided in the Amended Charter. PROPOSAL 4 SALE OF THE ASSETS USED IN OUR GENERIC FINISHED DOSAGE PRODUCT OPERATIONS LOCATED IN CONGERS, NEW YORK This section of the Proxy Statement describes certain aspects of the sale of substantially all of the assets used in the Company's manufacturing, labeling, packaging, storage, distribution and sale of finished dosage generic pharmaceutical products at its Congers, New York locations. The Company estimates that the assets to be sold represented approximately 30% of the Company's total assets as of December 31, 2003. Shareholders are urged to read carefully the complete Asset Purchase Agreement for the precise legal terms of the agreement and other important information. The Asset Purchase Agreement is attached as Appendix I to this Proxy Statement. While the Company is seeking shareholder approval for the sale of substantially all of its assets located in Congers, New York, the Company does not intend to wind up its affairs. The Company intends to use the proceeds from this sale, together with additional capital raised from the sale of securities to develop certain products utilizing its opioid abuse deterrent formulation technology and opioid synthesis technologies.

The Company, a New York corporation established in 1935, and its subsidiaries, have been engaged in the development, manufacture, sale and distribution of a variety of generic finished dosage pharmaceutical products and active pharmaceutical ingredients ("APIs"). Prior to the restructuring of the Company's operations largely completed on January 30, 2004, the generic drug products manufactured and sold by the Company generally consisted of an analgesic product, anti-infectives, antitussives, cough and cold preparations, and a steroid product. Since March 1999, the Company has manufactured active pharmaceutical ingredients ("APIs") at its Culver, Indiana facility and manufactured, packaged and sold its generic finished dosage products at two leased locations in Congers, New York. On November 6, 2003, the Company announced its plan to restructure the Company's operations to focus on research and development related to certain proprietary opioid synthesis and finished dosage formulation technologies. The Board of Directors determined, among other factors, that the Company's ability to generate positive cash flow from the operation of the Company's finished dosage manufacturing, packaging, labeling and distribution facilities located in Congers, New York (collectively, the "Congers Facilities") in the manufacture and distribution of finished dosage generic products pursuant to abbreviated new drug applications ("ANDAs") was compromised by the highly competitive market environment, low market pricing and declining market size for its existing generic products and the lack of new generic products in development. The Company incurred losses of $48.5 million in 2003, $59.6 million in 2002 and $12.6 million in 2001. The Board determined that near term sales of the Company's finished dosage generic products would likely result in negative gross margins in view of the market environment. Based on this analysis and other factors, the Board concluded that the Company's manufacture and sale of finished dosage products licensed to be produced at the Congers Facilities would result in continuing negative cash flow in the foreseeable future. After due consideration of alternative strategies and considering the optimal use of available funding, the Board adopted a strategy to substantially restructure the Company's business. The restructured operations will be conducted at the Company's Culver, Indiana facility and will include the following material components: - The development and commercial scale up of the Company's novel API opioid synthesis technologies at the Culver, Indiana facility. 68

- The prosecution of the Company's application to the DEA to receive a registration to import Narcotic Raw Materials ("NRMs") for use in the production of opioid API's. - The development of the Company's proprietary abuse deterrent formulation technologies for use in orally administered opioid containing finished dosage products. - The manufacture of clinical trial supplies of abuse deterrent formulations. - The evaluation of products utilizing abuse deterrent formulation technology in appropriate clinical trials. - Entering into license agreements with strategic partners providing that such licensees will further develop such abuse deterrent formulation finished dosage products, file for regulatory approval with the U.S. Food and Drug Administration ("FDA") and commercialize such products. - The Company's manufacture of commercial quantities of such products for sale by the Company's licensees. - The cessation of operations at the Congers Facilities and the sale of the assets used in such operations for manufacturing generic products. Shareholders are cautioned that there can be no assurance that the Company will succeed in implementing all or any portion of its restructured operations or, even if implemented, that the Company will succeed in the development and commercialization of its API opioid synthesis or finished dosage formulation technologies. Manufacturing of the Company's generic finished dosage products at the Congers Facilities substantially ceased on January 30, 2004. Such date also marks the completion, in large part, of the reduction in work force associated with the restructuring of the Company's operations by approximately 100 employees, 70 of whom were employed by the Company at the Congers Facilities. Operation of the Congers Facilities. Since March 1999, the Company has manufactured, labeled, packaged, distributed and sold a variety of generic prescription and over-the-counter products at its facilities in Congers, New York. The facilities in Congers consisted of a 35,000 square foot manufacturing facility located on Brenner Drive (the "Brenner Drive Facility"), and an 18,000 square foot packaging and labeling facility located at 125 Wells Avenue (the "Wells Avenue Facility" and collectively with the Brenner Drive Facility, the "Congers Facilities"). The lease agreement for the Brenner Drive Facility provided for annual fixed rent of approximately $600,000 per year. On March 19, 2004, the Company exercised the purchase option under the lease for the Brenner Drive facility, which included the right to purchase from the landlord the related leased equipment at the Brenner Drive Facility, and assigned the Company's rights under the contract of sale to IVAX. On the same day, simultaneous with the closing of the sale of the Brenner Drive Facility from Par Pharmaceutical, Inc. to IVAX, the Company terminated the lease for the Brenner Drive Facility. The lease also contained an option to purchase the facility and certain equipment subject to the lease for a price of $5.0 million, which purchase option was transferred to IVAX in accordance with the terms of the Asset Purchase Agreement. Simultaneous with the parties execution of the Asset Purchase Agreement on March 19, 2004, IVAX purchased the Brenner Drive Facility and the related leased equipment from the landlord of such facility. The lease agreement for the Wells Avenue Facility provides for annual fixed rent of approximately $135,000 per year and expires on June 30, 2004. The lease agreement for the Wells Avenue Facility was transferred to IVAX upon the parties' execution of the Asset Purchase Agreement. Prior to the cessation of manufacturing activities at the Congers Facilities the Company's operations at such facilities consisted of the manufacture, packaging, labeling, and distribution of approximately 12 dosage forms and strengths of prescription drugs and 4 dosage forms and strengths of over-the-counter products. Such products were sold in various forms, including liquids, tablets and capsules. In general, the generic drug products manufactured by the Company at the Congers Facilities consisted of an analgesic, anti-infectives antihistamine decongestants, antitussives and a steroid product. During fiscal 2003, the Company had net product revenues of $5.75 million, all of which were attributable to sales of finished dosage products 69

manufactured at the Congers Facilities. For the year ended December 31, 2003, the Company reported a net loss of $48.5 million, as compared to a net loss of $59.6 million for 2002. Development and Commercialization of Proprietary API and Finished Dosage Technologies. The Company has developed proprietary API opioid synthesis technologies that the Company believes provides an efficient and cost effective alternative to current technologies used to produce certain opioid APIs (the "API Technology"). The Company has also developed certain proprietary abuse deterrent formulation technologies which the Company believes can be applied to orally administered opioid containing finished dosage products.(the "ADF Technology"). The Company has filed three patent applications encompassing the API Technology and an application encompassing the ADF Technology with the U.S. Patent and Trademark Office. To date, only a limited portion of the Company's technologies have been tested in laboratory settings, none have been tested in clinical settings and all of such technologies will need to be successfully scaled up to be commercially viable, of which no assurance can be given. The development of the API Technology and the ADF Technology demonstrate the Company's continuing efforts to develop and manufacture APIs and finished dosage formulations focusing on opioid containing products. It is the Company's intention to continue focusing on opioids by developing novel manufacturing processes and finished dosage formulations incorporating the Company's technologies. Such development efforts may be performed solely by the Company or in partnership with third-party licensees. The Company's facility located in Culver, Indiana is registered by the U.S. Drug Enforcement Administration ("DEA") for research, development and manufacture of Schedule II to V controlled substances in bulk and finished dosage forms. In addition, the Company has filed an application with the DEA to obtain a registration to import NRMs directly from foreign sources for use in the Company's API manufacturing processes (the "Import Registration"). The Company's application for the Import Registration has been opposed by four parties, including the DEA and two firms that the Company believes represent the largest importers of NRMs used to manufacture opioid APIs in the U.S. Pursuant to established procedures, an evidentiary hearing relating to the Company's Import Registration application was held before a DEA Administrative Law Judge ("ALJ") in August 2003. The ALJ later re-opened the administrative record, at the request of opposing parties, to consider the Company's November and December 2003 announcements concerning Company restructuring and financing activities. Pursuant to the ALJ's order on March 30, 2004, the administrative record will remain open for at least 10 days following the Company's filing with the Securities and Exchange Commission of its annual report on Form 10-K to allow the opposing parties to file statements indicating whether they intend to submit additional evidence in response to such filing. Upon the closure of the administrative record, the ALJ will make findings of fact, draw legal conclusions and recommend a specific decision on the Company's Import Registration application to the DEA Deputy Administrator. The Deputy Administrator will then consider the ALJ's decision and administrative record and issue a final order relating to the Company's application. DEA will judge whether the issuance of an Import Registration is appropriate based on, among other considerations, whether adequate security safeguards and controls are maintained at the Culver Facility and at all points in the chain of transfer of the NRMs from foreign suppliers to its Culver Indiana facility, whether the AP1 Technologies are viable processes, whether market demand for opioid containing products or other factors support the approval of another import registration, and whether the Company has established itself as an eligible party to obtain NRMs for foreign sources. The Company must continue to maintain compliance with DEA's requirements for maintenance of its Manufacturing Registration in the meantime. Subsequent to the completion of the Company's sale to IVAX of the assets used in the operation of the Congers Facilities, the Company will focus on its opioid API Technologies and the ADF Technology. Assuming the Company is successful in its development relating to these technologies, of which no assurance can be given, the Company intends to vertically integrate its operations at a single location in Culver, Indiana (the "Culver Facility"). Beginning with NRMs and utilizing its opioid API Technology, the Company will manufacture bulk opioid APIs at the Culver Facility. Such bulk opioid APIs will be formulated and manufactured into finished dosage orally administered products utilizing the Company's ADF Technology. The Company expects to contract with third-party pharmaceutical companies to complete the development 70

and testing of such abuse deterrent products and to obtain required regulatory approvals and to commercialize such products. The Company's administrative office is located at 616 N. North Court, Suite 120, Palatine, Illinois 60067, and the telephone number is (847) 705-7709. The Company's website is www.halseydrug.com and the Company's annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports are made available to the public free of charge, as soon as reasonably practicable after the Company electronically files such material with, or furnishes it to, the Securities and Exchange Commission, by contacting us by telephone, mail or through our website. IVAX PHARMACEUTICALS NEW YORK LLC IVAX Pharmaceuticals New York LLC ("IVAX"), a wholly-owned subsidiary of IVAX Corporation, was formed for the purpose of completing the purchase of the assets used in the operation of the Congers Facilities.

BACKGROUND OF THE SALE OF ASSETS USED IN THE OPERATION OF THE CONGERS FACILITIES The decision of the Board to approve and recommend the Asset Purchase Agreement was the result of an extensive evaluation process. During the last few years, the Board and senior management have, from time to time, evaluated and considered a number of alternatives, including strategic partnerships, mergers and disposition transactions, all as more particularly described in this section below. On March 29, 2000, the Company completed various strategic alliance transactions with Watson Pharmaceuticals, Inc ("Watson"). The transactions with Watson provided for Watson's purchase of a certain pending abbreviated new drug application ("ANDA") from the Company, for Watson's rights to negotiate for Halsey to manufacture and supply certain identified future products to be developed by Halsey, for Watson's marketing and sale of the Company's core products, and for Watson's extension of a $17.5 million term loan to the Company. As part of its alliance with Watson, the Company and Watson executed a manufacturing and supply agreement providing for Watson's marketing and sale of the Company's existing core products portfolio (the "Core Products Supply Agreement"). The products subject to the Core Products Supply Agreement represented substantially all of the Company's then existing finished dosage product formulations. Concurrent with the execution of the Core Products Supply Agreement, Watson extended a $17.5 million term loan to the Company. The term loan was secured by a lien on all of the Company's assets, senior to the lien securing all other Company indebtedness, carried a floating rate of interest equal to prime plus 2% and had an original maturity date of March 31, 2003. In December 2002, as part of the Company's completion of an offering of convertible senior secured debentures, the Watson term loan was amended to (i) extend the maturity date to March 31, 2006, (ii) increase the interest rate to prime plus 4 1/2%, and (iii) increase the principal amount of a loan from $17.5 million to approximately $21.4 million to reflect the inclusion of the excess payments made by Watson to the Company under the Core Products Supply Agreement. In entering into the alliance with Watson, the Company's expectation was that sales of the Company's core products would increase through Watson's marketing and sales of such products under Watson's label. Additionally, the Company believed that the anticipated increased revenue from sales of the Company's products to Watson combined with the proceeds of the Watson term loan would provide a sufficient source of 71

working capital to allow the Company to develop and commercialize its proprietary API Technology and ADF Technology. As a result, and in accordance with the terms of the Core Products Supply Agreement, the Company ceased the direct marketing and sale of its products and, with the exception of the contract manufacture of certain products for third parties, supplied its products solely to Watson for marketing and sale under Watson's label. The alliance with Watson did not generate the results either party had originally expected. The Company's revenue during the years ended December 31, 2002, 2001 and 2000 (excluding revenue derived from the sale of the ANDA to Watson as a part of the Watson alliance) was $8.2 million, $8.4 million and $15.2 million, respectively, resulting in net losses during such fiscal years of ($59.6 million), ($12.6 million) and ($11.7 million), respectively. The disappointing results of the Watson alliance resulted in continuing operating losses and a shortage of working capital. As a consequence, and as described below, in order to continue operations, the Company was required to raise additional financing in the form of numerous bridge loans and private offerings of the Company's securities. Faced with declining product revenue and limited working capital, the Company secured bridge loan financing from Galen Partners, L.P. and its affiliates (collectively "Galen"), the largest holder of the Company's senior secured convertible debentures. Specifically, during the period from August 2001 through December 2002, Galen advanced an aggregate of $15.9 million in bridge loans to the Company to fund ongoing operations. The Galen bridge loans were evidenced by 10% convertible promissory notes and were secured by a lien on all of the Company's assets, junior to the security interest granted to Watson under the Watson term loan but senior to the security interest granted to secure all other Company indebtedness. In July 2002, the Board of Directors retained MTS Partners and CIBC as the Company's financial advisor to assist the Company in analyzing, planning, negotiating and executing the Company's strategic and financial plan, including the identification of a strategic partner or source of financing, or alternatively, an acquirer of the Company's business. Through the efforts of senior management and the Company's financial advisor, the Company solicited approximately 35 entities in an effort to form a strategic partnership, secure financing or negotiate a sale of the Company. As part of the discussions with such third parties, management presentations were made and a detailed descriptive memorandum describing the Company's operations was provided. While there was initial interest by a number of prospects, all of such prospects indicated an unwillingness even to entertain preliminary discussions or negotiations with the Company relating to a financing, strategic partnership or acquisition transaction. Reasons provided by such parties included, but not limited to, the absence of a strategic fit and the dilutive impact the acquisition of the Company would have on the acquirer's earnings. On December 20, 2002, the Company completed a private offering of securities for an aggregate purchase price of approximately $26.4 million (the "2002 Offering"). Securities issued in the 2002 Offering consisted of 5% convertible senior secured debentures (the "2002 Debentures"). The 2002 Debentures were issued by the Company pursuant to a certain debenture purchase agreement dated December 20, 2002 (the "2002 Purchase Agreement") by and among the Company, Care Capital Investment II, LP, Essex Woodlands Health Ventures V, L.P., Galen and the other purchasers listed on the signature page thereto. Of the approximate $26.4 million in 2002 Debentures issues in the 2002 Offering, approximately $15.9 million of 2002 Debentures were issued in exchange for the surrender of a like amount of principal and accrued interest under the Company's outstanding 10% convertible promissory notes issued to Galen and certain other lenders pursuant to bridge financing made during the period from August 2001 through December 2002. The proceeds of the 2002 Offering were used by Company for working capital and to fund continuing operating losses. Subsequent to completion of the 2002 Offering, senior management continued it efforts to identify a strategic partner or potential acquirer of the Company's business. Additionally, senior management implemented changes designed to contain costs and increase product sales. In March 2003, the Company notified Watson that the Company intended to commence the direct marketing and sale of the Company's core products in addition to sales of such products to Watson, as provided for under the Core Products Supply Agreement. The Company commenced the direct sale of its products in the summer of 2003. In view of the limited number of the Company's products and the intense market competition for these products, the 72

Company's direct sales of its core products did not result in significant revenue enhancement. This combined with steadily declining purchases by Watson under the Core Products Supply Agreement resulted in increasing operating losses and a shortfall of cash to fund operations. At the Company's request, on May 5, 2003, the Company received a letter executed by each of Care Capital, Essex Woodlands and Galen (the "Majority 2002 Debentureholders") advising that the Majority 2002 Debentureholders would provide funding to meet the Company's 2003 capital requirements, up to an aggregate amount not to exceed $8.6 million (the "Letter of Support"). During the period from May 2003 through December 31, 2003, the Majority 2002 Debentureholders advanced an aggregate of $8.6 million under the Letter of Support. Such advances were made in accordance with the terms of the 2002 Offering, resulting in the Company's issuance of additional 2002 Debentures in the aggregate principal amount of $8.6 million. The proceeds of the advances under the Letter of Support were used for working capital and to fund continuing operating losses. On August 26, 2003, the Company announced the appointment of Andrew Reddick as President and Chief Executive Officer, bringing with him approximately 29 years of pharmaceutical industry experience. Mr. Reddick replaced Michael Reicher whose services as Chief Executive Officer ceased effective June 16, 2003. Mr. Reddick immediately engaged in an assessment of the strengths and weaknesses of the Company's business operations, including the focus of the Company's research and development efforts and its dual-site vertical integration strategy. At Board meetings held on each of October 9, 2003 and October 30, 2003, Management reviewed with the Board the challenges inherent in operating two separate manufacturing locations with a limited existing product portfolio and a lack of any new products pending for approval and subsequent launch. At such time, the Company manufactured API at its Culver, Indiana facility and manufactured finished dosage form products at its facilities in Congers, New York. The Board evaluated the Company's operating losses and the inability to stem such losses in view of the Company's product mix, operating margins and lack of pending new product approvals. The Board determined that near term sales of the Company's finished dosage form generic products would likely result in continuing negative gross margins due to intense market competition and resultant decreasing market prices and market dollar volume. Based on this analysis and other factors, the Board concluded that the Company's manufacture and distribution of finished dosage generic products produced at the Congers facilities would result in continuing negative cash flow for the foreseeable future. In addition, the Board concluded that in the long term, due to the timing and uncertainty relating to the approval process for its application for an Import Registration for NRMs for use in the manufacture of opioid APIs at its Culver, Indiana facility, the Company would have difficulty sustaining operations faced with continuing operating losses and negative cash flow. On October 30, 2003, the Board approved the restructuring of the Company's operations. The restructuring provided, among other things, for the closure of the Congers Facilities and the sale of the assets used in such operations. The Company estimates that such assets represented approximately 30% of the Company's total assets as of December 31 2003. The Company publicly announced the implementation of the restructuring on November 6, 2003. On October 21, 2003, Management met with representatives of Watson in an effort to negotiate to convey to Watson the assets used in the operation of the Congers Facilities, including the Company's purchase option to acquire the Brenner Drive Facility, in consideration of restructuring the Watson term loan. Thereafter, on October 29, 2003 Watson conducted a site tour of the Congers Facilities and on November 7, 2004, Watson advised the Company that it was not interested in acquiring the Congers Facilities. In the three months following the Company's November 6, 2003 press release announcing the implementation of the restructuring of the Company's operations, the Company contacted, or was contacted by, a total of 21 parties expressing interest in the Congers Facilities. Such parties were provided with a detailed descriptive memorandum relating to the assets and operations of the Congers Facilities. The majority of such parties completed a tour of the facilities and varying degrees of diligence investigation. Of such parties four provided draft letters of intent outlining non-binding terms for the acquisition of the assets of the Congers 73

Facilities, including the direct purchase by such parties of the Brenner Drive Facility from the landlord of this site. During December, 2003 and January 2004, three of the four parties that provided a draft letters of intent notified the Company that based on the diligence they had completed, they had no further interest in an acquisition of the Congers Facilities. The remaining party that had provided a letter of intent to the Company and continued to express interest in completing an acquisition of the assets used in the operation of the Conger Facilities was IVAX. In the meantime, on each of November 25, 2003, December 21, 2003, December 29, 2003, January 5, 2004, January 20, 2004 and February 10, 2004, the Board of Directors held meetings to, among other things, review the status of the implementation of the restructuring of the Company's operations, review the progress of discussions with third parties relating to the proposed sale of the assets used in the operation of the Congers Facilities, review the Company's efforts to complete a financing involving a private offering of its securities, and review the Company's progress in restructuring the Watson term loan. At each of such meetings the Board instructed management to continue negotiations with all interested parties in an effort to maximize the value of the sale of the assets used in the operation of the Congers Facilities and to complete such sale on an expeditious basis. On January 26, 2004, Mr. Reddick received a call from Gerry Price, Vice President of Business Development of IVAX Corporation, expressing IVAX Corporation's interest in the Congers Facilities. Mr. Price was formerly the President of Halsey and resigned effective November 7, 2002. In view of Mr. Price's former role with the Company, he was familiar with the Company's operations at the Congers Facilities. On January 26, 2004 IVAX signed a confidentiality agreement with the Company. On January 27, 2004, the Company provided to Mr. Price the Company's draft template of a non-binding letter of intent contemplating IVAX' purchase of substantially all of the Company's assets used in the operation of the Congers Facilities, including the direct purchase by IVAX of the Brenner Drive Facility pursuant to the purchase option included in the Company's lease agreement for this site. On February 4, 2004 IVAX provided the Company with a non-binding letter of intent, generally following the form of the Company's template letter of intent. The IVAX initial letter of intent proposed a total aggregate purchase price for the Congers Assets, including certain products and equipment of $4.3 million, of which $1.5 million would be paid upon the closing of the purchase by IVAX of the Brenner Road Facility from the owner of such facility, with the balance of $2.8 million payable on the conveyance of substantially all of the Company's assets used in the operation of the Congers Facilities following shareholder approval of the sale of such assets. The IVAX non binding letter of intent was subject to, among other things, satisfactory completion of negotiations and due diligence. On February 6, 2004 nine representatives of IVAX Corporation toured the Congers Facilities for the first time and began an extensive due diligence process. At the end of the day on February 6, 2004, after completing a preliminary general assessment of the Congers Facilities, IVAX informed Company management that the total purchase price included in the February 4, 2004 non binding letter of intent would be reduced to an aggregate of $3.5 million due to the need, in the judgment of IVAX, for substantial upgrades to among other things, the air handling, heating, ventilation and air conditioning (HVAC) systems at the Brenner Road facility. Of the $3.5 million, $1.5 million was proposed to be paid at the execution of the asset purchase agreement, at which time IVAX would also purchase the Brenner Road Facility from the owner of such facility. The remaining $2.0 million would be paid upon receipt of approval of the Company's shareholders to the asset sale transaction. IVAX stated that the proposed aggregate payment of $3.5 million remained subject to further due diligence and a comprehensive inspection of the HVAC system. Over approximately the next week, representatives of the Company, IVAX and their respective legal counsel negotiated the terms of the letter of intent. During this period, senior management advised the Board as to the status and progress of the negotiations with IVAX. As part of the parties' negotiations, additional drafts of the letter of intent containing changes proposed by the parties were prepared and circulated. 74

On February 10, 2004, the Board of Directors met to discuss, among other things, the status of the negotiations with IVAX and the terms then proposed by IVAX for the acquisition of the Congers Facilities assets. The Board directed senior management to continue the negotiations with IVAX and authorized senior management to provide counterproposals as required. On or about February 14, 2004, the parties abandoned the process of negotiating and executing a non-biding letter of intent electing instead to negotiate the terms of the acquisition as part of the preparation and negotiation of the definitive asset purchase agreement. As a result, IVAX commenced the preparation of a draft asset purchase agreement and continued with its due diligence review of the Congers Facilities. In addition to further on-site diligence conducted by IVAX and the review of a variety of diligence information provided by the Company to IVAX and its legal counsel during February, 2004, IVAX conducted Phase I and Phase II environmental audits of the Brenner Drive Facility and the Wells Avenue Facility. Based on the results of the IVAX due diligence investigation, IVAX' further evaluation of the products included in the assets to be purchased, and the continuing negotiations between the Company and IVAX on asset value and number of other issues, the parties continued their negotiation of the asset purchase agreement. In the meantime, on February 6, 2004, the Company completed a private offering of securities for an aggregate purchase price of approximately $12.3 million (the "2004 Offering"). The securities issued in the 2004 Offering consisted of convertible senior secured debentures (the "2004 Debentures") and were issued by the Company pursuant to a certain debenture and share purchase agreement dated as of February 6, 2004 (the "2004 Purchase Agreement") by and among the Company, Care Capital, Essex Woodlands, Galen and the other purchasers listed on the signature page thereto. Of the approximate $12.3 million in 2004 Debentures issued in the 2004 Offering, $2.0 million of debentures were issued in exchanged for the surrender of a like amount of principal plus accrued interest under outstanding bridge loans advanced to the Company by Care Capital, Essex Woodlands and Galen during November and December, 2003. As part of the completion of the 2004 Offering, the Company paid Watson $4.3 million (derived from the proceeds of the 2004 Offering) to restructure the Watson term loan to, among other things, reduce the principal amount of the Watson term loan from approximately $21.4 million to $5.0 million. The restructured Watson term loan in the principal amount of $5.0 million was assigned to Care Capital, Essex, Galen and certain other purchasers of the 2004 Debentures in consideration for a cash payment by such parties to Watson of $1.0 million. The Company will use the net proceeds from the 2004 Offering to fund the development and commercialization of the Company's technologies and to fund operating expenses. On February 25, 2004, the Company received the initial draft of the asset purchase agreement from legal counsel for IVAX. The draft asset purchase agreement did not contain the purchase price or the allocation of the purchase price as between the First Closing and the Second Closing. During the period between February 26, 2004 and March 1, 2004, senior management and legal counsel for the Company held numerous telephonic meetings to review the draft asset purchase agreement and prepared a revised draft of the agreement to reflect the Company's comments. On March 2, 2004, the Company's legal counsel provided IVAX and its counsel with a revised draft of the asset purchase agreement. In addition to comments and revisions typical in the negotiations of this type of transaction, the Company inserted an aggregate purchase price of $3.5 million, $1.5 million of which was payable at the execution of the asset purchase agreement, with the $2.0 million balance payable at the closing of the asset purchase agreement following receipt of approval of the Company's shareholders. The Company's revised draft of the asset purchase agreement also provided for limited representations and warranties and certain limits on the Company's indemnity obligations. Between March 3 and March 5, 2004, legal counsel for the parties continued discussions and negotiations relating to the asset purchase agreement. On March 5, 2004, the parties and their respective legal counsel participated in a conference call to negotiate the remaining material open issues in the draft asset purchase agreement. At the conclusion of the conference call, after considering, among other things, IVAX' concerns relating to the HVAC system at the Congers Facilities and requirements for upgrades to the system, the parties had reached conceptual agreement (subject to finalizing and executing definitive agreements) providing for: (i) an aggregate purchase price of $2.5 million, payable $2.0 million at the execution of the asset 75

purchase agreement and $0.5 million at the closing of the asset purchase agreement following receipt of approval of the Company's shareholders, (ii) the conveyance of the Company's manufacturing equipment and products on an "as is" basis, and (iii) a limitation of the Company's indemnity obligations to the amount of the purchase price, subject to certain exceptions for representations relating to title, taxes and environmental matters. During the negotiations and discussions of the asset purchase agreement, senior management continually provided updates to the Board on the status of the negotiations and the resolution of material issues. On March 12, 2004, IVAX provided the Company and its legal counsel with a revised draft of the asset purchase agreement reflecting, among other items, the resolution of the material issues discussed during the conference call on March 5, 2004. During the period from March 12, 2004 through March 14, 2004, senior management and the Company's legal counsel reviewed and revised the asset purchase agreement and other related agreements. On March 14, 2004, Company legal counsel provided IVAX and its legal counsel with a revised draft of the asset purchase agreement and a use and license agreement. Between March 15 and March 18, 2004, negotiations and discussions of the definitive asset purchase agreement and related agreements between the Company, IVAX and their respective legal counsel progressed. On March 18, 2004, the Board of Directors, acting by unanimous written consent, approved the terms of the substantially complete asset purchase agreement and authorized senior management to negotiate such changes to asset purchase agreement and related agreements as were necessary to conclude the execution of the definitive agreement. Any changes made to the definitive asset purchase agreement and related transaction agreements during the period subsequent to the receipt of Board approval were not material and did not alter the consideration to be received by the Company as previously discussed with the Board. The purchase price was determined based upon arms'-length negotiations. As described below under the caption "Reasons for the Sale of the Congers Facilities Assets" the Board of Directors did not engage an independent financial advisor to determine the fairness of the asset sale transaction to the Company's shareholders. In approving the transaction to sell substantially all of the Company's assets used in the operation of the Congers Facilities, the Board considered, among other factors, the continuing losses from operations, the cessation of the manufacturing operations at the Congers Facilities, the March 21, 2004 expiration date of the lease agreement for the Brenner Drive Facility, the lack of capital resources to exercise the $5.0 million purchase option to purchase such facility, the cash consideration to be received by the Company, the assumption by IVAX of the Company's obligations under the lease agreement for the Wells Avenue Facility, and the overall structure of the transaction and the terms of the asset purchase agreement. In addition to the foregoing, the Board determined that the consideration to be received by the Company was fair considering the value ascribed to the assets by other third parties that had expressed initial interest in the assets, the Board's general familiarity with the value of pharmaceutical manufacturing and packaging facilities, and the arm's-length nature of the negotiations between the Company and IVAX. Based on the foregoing, the Board of Directors unanimously resolved to recommend that the Company's shareholders approve and adopt the asset purchase agreement and the sale of substantially all the assets used in the Company's operation of the Congers Facilities. The Asset Purchase Agreement was executed on March 19, 2004. The Company publicly announced the execution of the Asset Purchase Agreement on March 24, 2004. REASONS FOR THE SALE OF THE CONGERS FACILITIES ASSETS The Company is proposing to sell substantially all of the assets used by the Company in the operation of the Congers Facilities to IVAX, a wholly-owned subsidiary of IVAX Corporation. The Board of Directors believes that the sale and the terms of the related Asset Purchase Agreement are in the best interests of the Company and its shareholders. The Board of Directors has identified various benefits that are likely to result from the sale of the Congers Facilities assets. The Board believes that the sale of such assets will: - Allow the Company to direct its resources to the development and commercialization of the Company's opioid API Technologies and ADF Technology; 76

- Reduce the cash burn in the operation of the Company's business; - Provide an improved organizational focus and free up senior management from directing the operation of multiple development, manufacturing and administrative locations in separate states; - Allow the Company to a focus on a streamlined business strategy that the Board believes will provide competitive advantages potentially leading to greater return for the Company's shareholders; and - Allow the Company to increase its cash reserves by approximately $2.35 million (net of expenses) and thereby provide the Company with increased resources to continue the development of the Company's proprietary technologies and fund operating losses pending the commercialization of such technologies. As discussed above under the caption "Background", at Board meetings held on each of October 9, 2003 and October 30, 2003, Management reviewed with the Board the challenges inherent in operating two separate manufacturing locations with a limited existing product portfolio and a lack of any new products pending for approval and subsequent launch. At such time, the Company manufactured API at its Culver, Indiana facility and manufactured finished dosage form products at its facilities in Congers, New York. The Board evaluated the Company's operating losses and the inability to stem such losses in view of the Company's product mix, operating margins and lack of pending new product approvals. The Board determined that near term sales of the Company's finished dosage form generic products would likely result in continuing negative gross margins due to intense market competition and resultant decreasing market prices and market dollar volume. Having concluded that it would be prudent to consolidate remaining operations into a single site, the Board considered that the Congers, New York facilities were leased facilities whereas the Company owned the Culver, Indiana facility. Furthermore, in light of the restructured Company's primary focus on research and development, the Board chose to retain the Culver, Indiana facility given that the majority of the Company's research and development capabilities in terms of laboratory and personnel were based at such location. In arriving at its determination that the asset sale was in the best interests of the Company and its shareholders, the Board of Directors carefully considered the terms of the Asset Purchase Agreement as well as the potential impact of the asset sale on the Company. As part of this process, the Board of Directors consulted with senior management and considered the advice and assistance of Company legal counsel. In determining to authorize the asset sale, the Board of Directors considered the factors set out above as well as the following factors: - The fact that IVAX' offer, after completion of their due diligence, was the only offer the Company received that was not subsequently withdrawn, and following an extended search and evaluation process for alternative purchasers, it is the Board's belief that it was not likely that any party other than IVAX would propose and complete a transaction on terms more favorable to the Company and its shareholders; - The amount of cash included in the IVAX offer, the payment of such consideration at each of the signing of the Asset Purchase Agreement and the closing of the asset sale transaction, and the fact that IVAX agreed to assume the Company's liabilities under the lease agreement for the Wells Avenue Facility; - The terms and conditions of the Asset Purchase Agreement and the Board's belief that the Asset Purchase Agreement could be completed expeditiously without regulatory delay; - The fact that the sale of the Congers Assets must be approved by the holders of 66 2/3% of the Company's outstanding voting securities, which insures that the Board will not be taking action disapproved of by the Company's shareholders; and - The fact that New York law entitles shareholders who do not vote in favor of the Asset Purchase Agreement and the related transactions and who file a written notice of intent with the Company, to obtain the "fair value" for their shares as determined in accordance with New York's statutory procedures, if the transactions described in the Asset Purchase Agreement are completed. 77

The Board believed that each of the above factors generally supported its determination. The Board did, however, consider the potential adverse effects of other factors on the proposed asset sale as described below: - The risk that, after the asset sale, the Company will have no ability to manufacture finished dosage generic products and that all of the Company's previous revenue generating products will have been sold; - The fact that the finished dosage manufacturing, packaging, labeling and distribution operations conducted at the Congers Facilities represented essentially all of the Company's product revenues for fiscal 2003 and 2002; - The risk that the Company will be able to develop and commercialize the Company's proprietary technologies; - The fact that in the absence of the Company's ability to successfully develop and commercialize the Company's proprietary technologies, the Company will have no ability to generate revenues to partially offset operating expenses from sales of generic products; - The risk that the Company's cash resources to fund the development and commercialization of the Company's proprietary technologies and continuing operating losses may be insufficient to sustain the Company's cash needs until such time as revenues may be generated from such technologies; - The fact that the Company has a history of cash flow problems and may need to raise additional capital (if available to the Company) to develop and commercialize the Company's proprietary technologies; - The risk that the Company could be exposed to future indemnification obligations under the Asset Purchase Agreement which, in certain cases, could require the Company to make payments to IVAX in excess of the consideration received by the Company under the Asset Purchase Agreement; and - The risk that shareholders do not approve the asset sale, in which case the Company would be required to repay to IVAX the $2.0 million payment received from IVAX at the signing of the Asset Purchase Agreement. The foregoing represents all material factors considered by the Board in connection with its evaluation of the asset sale transaction. In view of the variety of factors considered in connection with its evaluation of the asset sale, the Board of Directors did not find it practical to and did not quantify or otherwise attempt to assign relative weights to the specific factors considered in reaching its conclusions. In addition, individual members of the Board may have given different weight to different factors and therefore may have viewed certain factors more positively or negatively than others. The Board of Directors did not engage an independent financial advisor to determine the fairness of the transactions to the Company's shareholders and determined, based on the factors set forth above, that the transactions contemplated by the Asset Purchase Agreement are fair to the Company's shareholders. Further, based on the procedural safeguard of the unanimous approval of our directors, including those directors who are not employees, the required approval of our shareholders and the availability of the dissenter's rights, the Board believes that the transactions contemplated by the Asset Purchase Agreement are procedurally fair to shareholders. A fairness opinion from an independent financial advisor typically entails a substantial fee to the requesting company. In the context of an asset sale, the financial advisor would typically review the Company's historical and projected revenues, operating results of that portion of the Company's business being sold and certain other publicly held companies it believed to be comparable to the business operations conducted at the Congers Facilities, and make certain assumptions regarding the value, including the liquidation value, of the assets and liabilities associated with such business operations, which may be difficult to predict, in order to render its opinion. In addition to the speculative nature of such analysis, the Board believes undertaking these analyses would involve a significant unnecessary expense that would reduce the amount of cash received by the Company in the proposed transaction that could be used to develop and commercialize the Company's proprietary technologies. The Board believes that the approval of the Asset Purchase Agreement by shareholders, together with the right of any shareholder that objects to the transaction to exercise the dissenter's rights to obtain fair value of their shares, provide procedural safeguards to the 78

shareholders in reaching its determination that the transactions contemplated by the Asset Purchase Agreement are fair to the Company's shareholders. See the discussion below under the caption "Dissenter's Rights". RECOMMENDATION OF THE BOARD OF DIRECTORS The Board of Directors has determined that the sale of the assets used in the operation of the Congers Facilities is in the best interest of the Company and its shareholders. The Board of Directors has unanimously approved the Asset Purchase Agreement and unanimously recommends that the Company's shareholders vote in favor of the proposal to approve the sale of the Congers Assets to IVAX pursuant to the Asset Purchase Agreement and the transactions contemplated by the Asset Purchase Agreement. PROCEEDS OF THE SALE OF THE CONGERS FACILITIES ASSETS The Company will retain the proceeds from the sale of the assets used at the Congers Facilities. After giving effect to legal and other professional fees relating to the asset sale transaction, the Company estimates that it will realize aggregate net proceeds from the asset sale of approximately $2.3 million. As described under Proposal 2 under the caption "Proceeds of 2004 Debenture Offering," as of June 1, 2004, the Company had issued 2004 Debentures in the aggregate principal amount of $14 million. After giving effect to (i) the issuance of $2.0 million in principal amount of 2004 Debentures in exchange for the surrender of a like amount of principal plus accrued interest outstanding under Company debentures issued in November and December 2003 pursuant to the Letter of Support, (ii) the payment to Watson of approximately $4.3 million in retirement of $16.4 million of indebtedness under the Watson Term Loan (See "Proposal 2 -- Interests of Investors in the 2004 Debenture Offering"), and (iii) the satisfaction of legal and other professional fees of approximately $400,000 relating to the 2004 Debenture Offering, the Company estimates that it will realize net proceeds from the 2004 Debenture Offering of approximately $7.3 million. The aggregate net proceeds of the asset sale transaction and the 2004 Debenture Offering received as of June 1, 2004, combined with the Company's other cash balances and reduced by operating expenses through May 31, 2004 provided the Company with approximately $7.3 million in cash reserves as of June 1, 2004 to fund the Company's development and commercialization of its proprietary technologies. Set forth below is a summary of the Company's estimated allocation of its cash resources as of June 1, 2004 to the development of its proprietary technologies and funding of operations.

USE ITEM AMOUNT - -------- ------------ Research & Development of ADF Technology Product, including clinical trials........................................... $ 3,250,000 Research & Development of Opiod Synthesis Technologies...... $ 600,000 Administration (i.e., insurance, finance, investor relations, employee benefits, legal, market research)..... $ 2,000,000 Personnel (i.e., salaries, bonuses, payroll taxes).......... $ 1,450,000 ------------ $7.3 million ============
While no assurance can be given, Management estimates that the existing cash on hand at June 1, 2004 of $7.3 million will fund activities through the first quarter of 2005. As of such time, the Company estimates that it will have completed initial clinical trials of a product incorporating the ADF Technology and will have entered into one or more licensing agreements for such product with a third party. The Company expects that the payments to be derived from such licensing agreements will provide the Company with the necessary additional funding to continue operations and to expand and expedite its development efforts. The ability of the Company to enter into a license agreement with a third party and the consideration to be received by the Company as part of any such agreement is primarily dependent upon the favorable outcome of the initial clinical trials of the Company's products, of which no assurance can be given. 79

SHAREHOLDER APPROVAL OF THE SALE OF THE CONGERS FACILITIES ASSETS; VOTE REQUIRED. Under Section 909 of the New York Business Corporation Law, the sale of "all or substantially all" of the Company's assets requires approval by the affirmative vote of two-thirds of all outstanding voting securities entitled to vote thereon. The Company, in consultation with legal counsel, has determined that the sale of the Congers Assets might be deemed to constitute a sale of "all or substantially all" of the Company's assets based on interpretations of that term. The Asset Purchase Agreement provides that, as a condition to each party's obligation to consummate the Second Closing contemplated by the Asset Purchase Agreement, the Company must have obtained the consent of its shareholders pursuant to the New York Business Corporation Law. Therefore, the affirmative vote of the holders of at least two-thirds of the Company's outstanding voting securities entitled to vote on the record date must be obtained. DISSENTER'S RIGHTS Pursuant to Section 910 of the New York Business Corporation Law ("NYBCL"), holders of the Company's Common Stock who follow the procedures set forth in Section 623 of the NYBCL (the "Appraisal Statute") will be entitled to have their Common Stock appraised by a New York State Court and to receive payment of the "fair value" of such shares as determined by such court. The Appraisal Statue is reprinted in its entirety as Appendix B to this Proxy Statement. While the following discussion summarizes all material terms of the law pertaining to appraisal rights under the NYBCL, it is qualified in its entirety by the full text of the Appraisal Statute. Any shareholder who wishes to exercise such appraisal rights or to preserve the right to do so, should review the following discussion and Appendix B carefully because failure to timely and properly comply with the procedures specified will result in the loss of dissenters' appraisal rights under the NYBCL. All references in the Appraisal Statute and in this summary to a "shareholder" are to the recordholder of the Company's Common Stock on the Record Date. A person having a beneficial interest in shares of the Company's Common Stock that are held of record by another person such as a broker or nominee must act promptly to cause the record holder to follow the steps summarized below properly and in a timely manner to perfect whatever appraisal rights the beneficial owner may have. A shareholder wishing to exercise appraisal rights must (i) deliver to the Company, prior to or at the Meeting but before the vote is taken on this Proposal 4, a written objection to the proposed sale of the Company's assets as provided in this Proposal 4 (the "Notice of Election"), which must include a notice of his election to dissent, the shareholder's name, residence address, the number of shares as to which the shareholder dissents and a demand for payment of the fair value of such shares (which Notice of Election must be in addition to and separate from any proxy or vote against the proposed sale of the Company's assets contemplated by this Proposal 4 (the "Asset Sale")) and (ii) not vote for approval of the Asset Sale. BECAUSE A PROXY WHICH DOES NOT CONTAIN VOTING INSTRUCTIONS WILL, UNLESS REVOKED, BE VOTED FOR APPROVAL OF THE ASSET SALE, A SHAREHOLDER WHO VOTES BY PROXY AND WHO WISHES TO EXERCISE APPRAISAL RIGHTS MUST (A) VOTE AGAINST APPROVAL OF THE ASSET SALE OR (B) ABSTAIN FROM VOTING ON THE ASSET SALE. Neither a vote against the Asset Sale, in person or by proxy, nor a Proxy directing such vote for an abstention, will in and of itself constitute a written objection to the Asset Sale under the Appraisal Statute (shareholders who timely file such Notice of Election and who do not vote in favor of the Asset Sale are referred to as "Dissenting Shareholders"). A shareholder may not dissent as to less than all of the shares, as to which such shareholder has a right to dissent, held by such shareholder of record and owned beneficially. A nominee or fiduciary may not dissent on behalf of any beneficial owner as to less than all of the shares held of record by such nominee or fiduciary on behalf of such owner and as to which such nominee or fiduciary has a right to dissent. All Notices of Election should be addressed to Halsey Drug Co., Inc., 616 N. North Court, Suite 120, Palatine, Illinois 60067, Attention: Mr. Peter Clemens, Senior Vice President. Within 10 days after the date on which shareholders approve the Asset Sale, the Company must send written notice by registered mail to each Dissenting Shareholder to such effect (the "Dissenting Shares"). At the time of the completion of the Asset Sale transaction by the Company (the "Effective Time"), each 80

Dissenting Shareholder will cease to have any rights of a shareholder of the Company except the right to be paid the fair value of his shares and rights under the Appraisal Statute. A Notice of Election may be withdrawn by a Dissenting Shareholder prior to his acceptance in writing of an offer made by the Company to pay the value of such Dissenting Shares, except that a Notice of Election may not be withdrawn later than 60 days following the Effective Time unless the Company fails to make a timely offer to pay such value, in which case such Dissenting Shareholder shall have 60 days from the date an offer is made to withdraw his election. In either event, after such time, a Notice of Election may not be withdrawn without the written consent of the Company. In order to be effective, withdrawal of a Notice of Election must be accompanied by a return to the Company of any advance payment made to the Dissenting Shareholder by the Company as described below. Upon filing the Notice of Election, or within one month thereafter, Dissenting Shareholders must submit the certificates representing their Common Stock to the Company, attention: Peter Clemens, Senior Vice President, at the address set forth above or to the Company's transfer agent, Continental Stock Transfer and Trust Company, 2 Broadway, 19th Floor, New York, New York 10004 and there will be noted thereon that a Notice of Election has been filed and the certificates will be returned to the Dissenting Shareholders. Any Dissenting Shareholders who fail to submit such certificates for such notation will, at the option of the Company exercised by written notice to such Dissenting Shareholders within 45 days of the date of filing of such Notice of Election, lose their appraisal rights unless a court, for good cause shown, shall otherwise direct. Within 15 days after the expiration of the period within which shareholders may file their Notice of Election, or within 15 days after the Effective Time, whichever is later (but in no case later than 90 days after the shareholders' vote to approve the Asset Sale), the Company must make a written offer to pay for the Dissenting Shares held by such Dissenting Shareholder at a price which the Company considers to be their fair value. This offer will be accompanied by a statement setting forth the aggregate number of shares, which will be at the same price for all Dissenting Shares, with respect to which Notices of Election to dissent have been received and the aggregate number of holders of such shares. If the Effective Time has occurred at the time the offer is made, the offer will be accompanied by (i) advance payment to each Dissenting Shareholder who has submitted certificates for notation thereon of the election to dissent of an amount equal to 80% of such offer or (ii) as to each Dissenting Shareholder who has not yet submitted certificates for notation thereon of the election to dissent, a statement that advance payment of an amount equal to 80% of the amount of such offer will be made by the Company promptly upon submission of certificates. If the Effective Time of the Asset Sale has not occurred at the time of the making of such offer, such advance payment or statement as to advance payment will be sent to each Dissenting Shareholder entitled thereto upon the Effective Time. Acceptance of such advance payment by a Dissenting Shareholder will not constitute a waiver of dissenter's rights. If the Asset Sale transaction is not completed within 90 days after approval of the Asset Sale by shareholders, such offer will be conditioned upon consummation of the Asset Sale. If within 30 days after making such offer, the Company and any Dissenting Shareholder agree on the price to be paid for such Dissenting Shareholder's Dissenting Shares, the Company will pay the agreed price to such holder within 60 days after the later of the date such offer was made or the Effective Time, upon surrender of certificates representing such holder's Common Stock. If the Company fails to make an offer within the 15-day period described above, or if it makes an offer and any Dissenting Shareholder fails to agree within 30 days of the making of such offer, the Company must, within 20 days thereafter institute a special proceeding in an appropriate court to determine the rights of Dissenting Shareholders and to fix the fair value of the shares. If the Company does not institute such a proceeding within such 20-day period, any Dissenting Shareholder may, within 30 days after such 20-day period expires, institute a proceeding for the same purpose. If such proceeding is not instituted by any Dissenting Shareholder within such 30-day period, all dissenters' rights will be extinguished unless the New York Supreme Court, for good cause shown, otherwise directs. All Dissenting Shareholders, other than those who agree with the Company as to the price to be paid for their shares, will be made parties to such proceeding 81

With respect to Dissenting Shareholders entitled to payment, the court will proceed to fix the value of the Company's Common Stock which will be the fair value as of the close of business on the day prior to the Meeting. In fixing the fair value of the shares of the Company's Common Stock, the court will consider the nature of the Asset Sale and the effects on the Company and its shareholders, the concepts and methods then customary in relevant securities and financial markets for determining fair value of shares of a corporation engaging in a similar transaction under comparable circumstances and all other relevant factors. The court will determine the fair value of such shares without a jury and without referral to an appraiser or referee. The final order by the court will include an allowance for interest (unless the court finds the refusal of any Dissenting Shareholder to accept the offer of the Company thereof as arbitrary, vexatious, or otherwise not in good faith) of such rate as the court finds to be equitable, accruing from the Effective Time to the date of payment. Each party in the appraisal proceeding will bear its own costs and expenses, including the fees of counsel and any experts employed by it. The court may, however, in its discretion, assess any of the costs, fees and expenses incurred by the Company against Dissenting Shareholders (including those who withdraw their Notice of Election) if the court finds that their refusal to accept the offer of the Company was arbitrary, vexatious or otherwise not in good faith. Similarly, the costs, fees and expenses incurred by Dissenting Shareholders may be assessed by the court in its discretion, against the Company if the fair value of the shares as determined by the court materially exceeds the amount which the Company offered to pay, the Company failed to follow certain procedures of the Appraisal Statute or the Company's manner of compliance with the Appraisal Statue was arbitrary, vexatious or not otherwise in good faith. Within 60 days after the final determination of the proceeding, the Company will pay to each Dissenting Shareholder the amount found in such proceeding to be due such shareholder, upon surrender of certificates of the Company's Common Stock. Any shareholder who duly demands, prior to the Meeting, an appraisal in compliance with the Appraisal Statute will not, after the Effective Time, be entitled to vote the shares subject to such demand for any purpose or to the payment of dividends or other distributions on those shares, except dividends or other distributions payable to shareholders of record as of a date prior to the Effective Time. Failure to follow the steps required by the Appraisal Statute for perfecting appraisal rights may result in the loss of such rights. IN VIEW OF THE COMPLEXITY OF THE PROVISIONS OF THE APPRAISAL STATUTE, SHAREHOLDERS WHO ARE CONSIDERING DISSENTING FROM THE ASSET SALE SHOULD CONSULT THEIR LEGAL ADVISORS. REGULATORY MATTERS No material regulatory approvals, filings or consents, other than filings in compliance with applicable Commission requirements, are required to complete the sale of the assets used in the operation of the Congers Facilities. ACCOUNTING TREATMENT The proposed sale of substantially all of the Company's assets used in the operation of the Congers Facilities and the assignment of certain related liabilities will be accounted for as a disposition of assets. As of December 31, 2003, the related assets of the Congers facilities had been written down to their estimated net realizable value of approximately $2.0 million. MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES The following describes the material United States federal income tax consequences of the proposed sale of substantially all of the Company's assets used in the operation of the Congers Facilities that are generally applicable to the Company and the shareholders. The following discussion is based on current provisions of the Internal Revenue Code, existing, temporary and proposed Treasury regulations thereunder and current administrative rulings and court decisions. Future legislative, judicial or administrative actions or decisions, 82

which may be retroactive in effect, may affect the accuracy of any statements in this summary with respect to the transactions entered into or contemplated prior to the effective date of those changes. The proposed sale of the assets used in the Company's operation of the Congers Facilities will be a transaction taxable to the Company for United States federal income tax purposes. The Company will recognize taxable income equal to the amount realized on the sale in excess of the Company's tax basis in the assets sold. The amount realized on the sale will consist of the cash the Company receives in exchange for the assets sold, plus the amount of related liabilities assumed by IVAX. The taxable income is estimated to be less than $250,000. Although the sale of the assets used by the Company in the operation of its Congers Facilities will result in a taxable gain to the Company, the Company's available federal income tax net operating and net capital loss carry forwards, as currently reflected on the Company's consolidated federal income tax returns, are in excess of the estimated amount of the gain. The Company's shareholders will experience no federal income tax consequences as a result of the consummation of the proposed sale of the assets used in the operation of the Congers Facilities to IVAX. The Company files income tax returns in more than one state. Because state income tax laws do not necessarily follow federal law, and because state laws themselves differ, the state income tax consequences of the sale of the assets to IVAX will vary state by state. The tax loss carry forwards in a particular state may not completely offset state taxable income and state income tax may be incurred on the sale. However, it is not anticipated that the sale will result in a material amount of state income taxes. VOTING AGREEMENT As a condition to the execution of the Asset Purchase Agreement, the Company, IVAX and the holders of substantially all of the Company's outstanding convertible debentures possessing voting rights and certain other holders of the Company's common stock, consisting of Galen Partners, III, L.P., Galen Partners International III, L.P., Galen Employee Fund III, L.P., Oracle Strategic Partners, L.P., Care Capital Investments II, LP, Essex Woodlands Health Ventures V, L.P., Alan Smith, a director of the Company, Andrew Reddick, President and Chief Executive Officer of the Company, Peter Clemens, Senior Vice President and Chief Financial Officer of the Company, William Skelly, a director of the Company, James Emigh, Vice President of Marketing and Administration of the Company, Patrick Coyne, Michael and Susan Weisbrot, Greg Wood, Dennis Adams, Bernard Selz, Roger Griggs, Hemant and Varsha Shah, Stephanie Heitmeyer, Michael and Ilene Rainisch, Kenneth Gimbel, Michael Reicher Trust, Peter Stieglitz, George Boudreau and John Heppe, Jr., (the "Asset Sale Voting Agreement Parties"), executed a voting agreement dated as of March 19, 2004 (the "Voting Agreement"). The aggregate voting securities held by the Asset Sale Voting Agreement Parties is approximately 51.5 million shares, representing approximately 78.4% of the Company's voting securities. The Asset Sale Voting Agreement Parties have agreed to vote in favor of the proposal to sell substantially all of the assets used in the operation of the Congers Facilities to IVAX pursuant to the terms of the Asset Purchase Agreement. Given the aggregate voting securities held by the Asset Sale Voting Agreement Parties, the approval of the proposal to sell substantially all of the assets used in the operation of the Congers Facilities by at least two-thirds of the Company's voting securities is assured. A copy of the Voting Agreement is attached as Appendix K to this Proxy Statement. SPECIAL CONSIDERATIONS SHAREHOLDERS SHOULD TAKE INTO ACCOUNT IN DECIDING HOW TO VOTE ON THE PROPOSAL TO SELL THE ASSETS USED IN THE OPERATION OF THE CONGERS FACILITIES. Shareholders should carefully consider the special considerations described below as well as other information provided in this Proxy Statement in deciding how to vote on the proposal to sell substantially all of the Company's assets used in the operation of the Congers Facilities. The special considerations described below are not necessarily the only ones facing the Company. Additional considerations not presently known to the Company or that are currently perceived as immaterial may also impair the Company's business operations. If any of the following special considerations occur, the Company's business, financial condition or 83

results of operations could be materially adversely affected, the value of the Company's common stock could decline and shareholders may lose part or all of their investment. SPECIAL CONSIDERATIONS REGARDING THE PROPOSAL TO SELL THE CONGERS FACILITIES ASSETS THE AMOUNT OF CASH THE COMPANY ULTIMATELY RECEIVES IN THE ASSET SALE TRANSACTION MAY VARY DEPENDING ON SOME FURTHER CONTINGENCIES, SUCH THAT THE COMPANY MAY NOT RECEIVE ALL OF THE CASH PROVIDED IN THE ASSET PURCHASE AGREEMENT. Pursuant to the terms of the Asset Purchase Agreement, the Company may be subject to potential indemnification claims relating to any inaccuracy in any representation or the breach of any warranty made by the Company in the Asset Purchase Agreement, the failure to perform or observe any covenant or agreement in the Asset Purchase Agreement and claims related to liabilities and obligations that IVAX has not assumed. Additionally, the Asset Purchase Agreement provides IVAX with certain rights of set off against the remaining $500,000 payment to be made by IVAX to the Company at the Second Closing relating to such indemnification obligations. While the Company's indemnification obligations in general are capped at the amount of the purchase price paid by IVAX to the Company, there are certain indemnification obligations for which the Company's liability could exceed the payments received from IVAX. Significant indemnification claims by IVAX could have a material adverse effect on the Company's business. THERE IS NO PLAN TO DISTRIBUTE ANY OF THE PROCEEDS OF THE ASSET SALE TO THE COMPANY'S SHAREHOLDERS. The Company does not intend to distribute to shareholders any portion of the proceeds from the sale of substantially all of the Company's assets used in the operation of the Congers Facilities. Currently, the Company intends to use the proceeds from the asset sale to fund the development and commercialization of the Company's proprietary technologies. THE FAILURE TO COMPLETE THE SALE OF THE ASSETS USED IN THE OPERATION OF THE CONGERS FACILITIES MAY RESULT IN A DECREASE IN THE MARKET VALUE OF THE COMPANY'S COMMON STOCK AND MAY CREATE SUBSTANTIAL DOUBT AS TO THE COMPANY'S ABILITY TO IMPLEMENT THE COMPANY'S BUSINESS STRATEGY. The sale of substantially all of the Company's assets used in the operation of the Congers Facilities is subject to a number of contingencies and other customary closing conditions, including the requirement that the Company obtain shareholder approval to complete the sale of the Congers Assets. In addition, the Asset Purchase Agreement may be terminated if the sale does not occur on or before ten (10) days following the receipt of shareholder approval or if any governmental authority takes any action to enjoin the asset sale. The Company cannot guarantee that it will be able to meet the closing conditions set forth in the Asset Purchase Agreement or that the events that would lead to a termination of the Asset Purchase Agreement will not occur. As a result, the Company is unable to assure shareholders that the sale of the assets used in the operation of the Congers Facilities will be completed. If the Company's shareholders fail to approve the asset sale proposal or if the asset sale is not completed for any other reason, the market price of the Company's common stock may decline. In addition, the failure to complete the asset sale may substantially limit the Company's ability to implement its business strategy. IF SHAREHOLDERS DO NOT APPROVE THE ASSET SALE, THERE MAY NOT BE ANY OTHER OFFERS FROM POTENTIAL ACQUIRERS. If shareholders do not approve the sale of the Congers Assets to IVAX, the Company would seek another purchaser for such assets. It is likely that the value of such assets would be substantially compromised since the Company would not have the manufacturing and packaging facilities available to enhance the value of such assets. Additionally, although the Company has had discussions with numerous parties concerning the purchase of such assets, with the exception of IVAX, after completion of due diligence, none of such parties expressed a willingness to purchase the assets. 84

SPECIAL CONSIDERATIONS RELATING TO THE COMPANY IF THE ASSETS USED IN THE OPERATION OF THE CONGERS FACILITIES ARE SOLD. THE COMPANY'S FINANCIAL SUCCESS WILL DEPEND ON ITS ABILITY TO SUCCESSFULLY IMPLEMENT ITS NEW BUSINESS STRATEGY. In accordance with the restructuring of the Company's operations, the Company is transitioning to a single vertically integrated site located at its Culver, Indiana facility. At such site, the Company will seek to develop and commercialize its proprietary API and finished dosage formulation technologies and ultimately, manufacture APIs and finished dosage products for sale by third-party licensees of the Company's technologies. The development and commercialization of APIs and finished dosage products incorporating the Company's proprietary technologies are subject to various factors, many of which are outside the Company's control. For instance, only a limited portion of the Company's technologies have been tested in laboratory settings and none have been tested in clinical settings. Such technologies will need to be successfully scaled up to commercial scale to be commercially viable. The Company is currently unable to provide any assurance that any of such technologies can be scaled up to commercial scale or that they will be commercially viable. The Company is committing substantially all of its resources and available capital to the development of its proprietary technologies. The Company's failure to successfully develop such technologies will have a material adverse effect on the Company's operations and financial condition. THE COMPANY HAS NO NEAR TERM SOURCES OF REVENUE AND MUST RELY ON CURRENT CAPITAL RESOURCES AND THIRD PARTY FINANCING TO FUND OPERATIONS. Pending the completion of the development and commercial scale up of the Company proprietary technologies, and the receipt of regulatory approval of products incorporating such technologies, of which no assurance can be given, the Company must rely on its current capital resources and available third-party financing to fund the Company's operations. As a consequence of the Company's restructuring of operations, including the cessation of its finished dosage manufacturing and packaging operations at the Congers Facilities and the proposed sale of the related assets to IVAX, the Company will have no ability to generate revenues from the sale of generic products. As a result, the Company must rely on its current cash resources or available third-party financing to fund operations. As of June 1, 2004, the Company had cash and cash equivalents of approximately $7.3 million, plus an additional $500,000 to be paid by IVAX on the closing of the asset sale transaction following the receipt of shareholder approval. No assurance can be given that such cash resources will be sufficient to fund the continued development and commercialization of the Company's proprietary technologies until such time as the Company generates revenue from the license of products incorporating such technologies to third parties. Moreover, in the event of a cash shortfall, no assurance can be given that the Company will succeed in raising additional financing to fund operations or that if funding is obtained, that such funding will be sufficient to fund operations until the Company's proprietary technologies, or products incorporating such proprietary technologies, may be commercialized. THE COMPANY RECEIVED A "GOING CONCERN" OPINION FROM ITS INDEPENDENT AUDITORS, HAS A HISTORY OF OPERATING LOSSES AND MAY NOT ACHIEVE PROFITABILITY SUFFICIENT TO GENERATE A POSITIVE RETURN ON SHAREHOLDERS' INVESTMENT. The Company has incurred net losses since 1992. The Company's consolidated financial statements for the year ended December 31, 2003 and the quarter ended March 31, 2004 have been prepared on a going-concern basis, expressing substantial doubt about the Company's ability to continue as a going-concern as a result of recurring losses and negative cash flows. The Company's loss from operations for the year ended December 31, 2003 and the three months ended March 31, 2004 was $17.2 million and $1.8 million, respectively. The Company's accumulated deficit as of March 31, 2004 was $208.8 million. The Company expects to incur net operating losses at least through 2004. There can be no assurance that the Company will ever generate revenues or achieve profitability at a level sufficient to generate a positive return on shareholders' investment. If the Company is unable to successfully develop and commercialize its proprietary technologies with its currently available cash resources or available sources of third-party financing, the Company's ability to execute its business plan and remain a going-concern will be significantly impaired. 85

THERE CAN BE NO ASSURANCE THAT EVEN IF THE COMPANY IS SUCCESSFUL IN DEVELOPING AND COMMERCIALIZING ITS PROPRIETARY TECHNOLOGIES, THAT PRODUCTS INCORPORATING SUCH TECHNOLOGIES WILL BE ACCEPTED IN THE MARKET. The commercial success of products incorporating the Company's technologies that are approved for marketing by the FDA and other regulatory authorities will depend upon their acceptance by the medical community and third party payors as clinically useful, cost effective and safe. There can be no assurance that, even if the Company succeeds in the development of products incorporating its technologies and receives FDA approval for such products, that the Company's products will be accepted by the medical community and others. Factors that the Company believes could materially affect market acceptance of its products include: - The relative advantages and disadvantages of the Company's technologies and timing to commercial launch of products utilizing such technologies compared to products incorporating competitive technologies; - The timing of the receipt of market approvals and the countries in which such approvals are obtained; - The safety and efficacy of products incorporating the Company's technologies as compared to competitive products; and - The cost-effectiveness of the products incorporating the Company's technologies and the ability to receive third party reimbursement. THE COMPANY MUST OBTAIN REQUIRED REGULATORY APPROVALS FROM THE FDA AND DEA. The Company's business strategy focuses on the development of opioid containing products incorporating the Company's proprietary technologies. The development, marketing and sale of products incorporating the Company's technologies is subject to extensive regulation by the DEA and FDA. At present, the Company's facility located in Culver, Indiana is approved to manufacture Schedule II to V controlled substance APIs and finished dosage products. To continue the development and commercialization of the Company's API Technologies, the Company is seeking to obtain a registration from the DEA to import narcotic raw materials ("NRMs") and has begun the application process seeking approval to import NMRs directly from foreign countries for use in the Company's opioid API manufacturing efforts. As part of the DEA's analysis of whether to issue to the Company an import registration, the DEA will consider, among other things, whether adequate security and controls exist at the Company's Culver, Indiana facility and at all points in the chain of transfer of NRMs from suppliers in foreign countries to the Culver, Indiana facility, whether the Company's API Technologies are viable and efficient processes, whether the United States market demand for opioid containing products supports the approval of another import registration, and whether the Company has established itself as an eligible party to source and obtain NRMs from foreign countries. No assurance can be given that the Company will have the capital necessary to complete additional capital improvements at its Culver, Indiana facility, that the Company will succeed in establishing sources in foreign markets to meet DEA requirements, or that the DEA will determine that the Company's API Technologies and the market demand for opioid containing products merit the approval of another NRM importer. Three of the four existing parties possessing import registrations are opposed to the proposed issuance by the DEA of an import registration for NRMs to the Company. These parties are Mallinckrodt Inc. of St. Louis, MO, Noramco of Athens, GA and Penick Corporation of Newark, NJ. Such opposing parties have advised the DEA that they believe the market for NRMs is adequately serviced by the parties currently authorized by the DEA to import NRMs and that the importation of additional NRMs would lead to increased illegal diversion of the resulting controlled substances. A hearing before the Office of Administrative Law Judge ("OALJ") relating to the Company's application for an Import Registration for NRMs was held in the third quarter of 2003. The process requires all parties to submit evidence relating to the Import Registration to the OALJ. Thereafter the evidentiary record will be closed and the OALJ will then establish a schedule for the parties to submit written briefing documents. Thereafter the OALJ will prepare a Findings of Fact, Conclusions of Law, Rulings and a Decision (the "OALJ Report"). The Company and the opposing parties will be provided an opportunity to comment on the OALJ Report after which time such report will be 86

forwarded to the DEA Administrator and certified by the OALJ. Thereafter the DEA Administrator will issue an order granting or denying the Company's application for the Import Registration. Either the Company or the opposing parties may file a petition for judicial review of such order in the U.S. Court of Appeals. No assurance can be given that the Company's application for the Import Registration will be granted or if granted, that such decision will be upheld by the U.S. Court of Appeals. THE MARKETING AND SALE OF PRODUCTS INCORPORATING THE COMPANY'S TECHNOLOGIES REQUIRES FDA APPROVAL WHICH CAN BE TIME-CONSUMING AND EXPENSIVE. The development, testing, manufacture, marketing and sale of pharmaceutical products are subject to extensive federal, state and local regulation in the United States and other countries. The regulatory approval process and the Company's ongoing compliance with FDA regulations, is time-consuming and often expensive. Substantially all of the Company's activities are subject to compliance with FDA regulations. Failure to adhere to applicable FDA regulations would have a material adverse effect on the Company's financial condition. In addition, in the event the Company is successful in developing products for sale in other countries, the Company would be subject to regulation in such countries. The Company may encounter delays or rejections during any stage of the regulatory approval process based upon the failure of clinical or laboratory data to demonstrate compliance with, or upon the failure of the product to meet, the FDA's requirements for safety, efficacy and quality. After the Company's submission to the FDA of a marketing application, in the form of a new drug application and/or a 505(b)(2) application the FDA may deny the application, may require additional testing or data and/or may require post-marketing testing and surveillance to monitor the safety or efficacy of a product. The FDA commonly takes one to two years to grant final approval to a marketing application. Further, the terms of approval of any marketing application, including the labeling content, may be more restrictive than the Company desires and could affect the marketability of products incorporating the Company's technologies. The FDA also has the authority to revoke or suspend approvals of previously approved products for cause, to debar companies and individuals from participating in the drug-approval process, to request recalls of allegedly violative products, to seize allegedly violative products, to obtain injunctions to close manufacturing plants allegedly not operating in conformity with current Good Manufacturing Practice regulations and to stop shipments of allegedly violative products. Any future source of Company revenue will be derived from the sale of FDA approved products, and the taking of any such action by the FDA would have a material adverse effect on the Company. THE COMPANY MAY BECOME INVOLVED IN PATENT LITIGATION OR OTHER INTELLECTUAL PROPERTY PROCEEDINGS RELATING TO IS PRODUCTS OR TECHNOLOGIES WHICH COULD RESULT IN LIABILITY FOR DAMAGES OR STOP THE COMPANY'S DEVELOPMENT AND COMMERCIALIZATION EFFORTS. The pharmaceutical industry has been characterized by significant litigation and other proceedings regarding patents and other intellectual property rights. The situations in which the Company may become a party to such litigation or proceedings include: - The Company may initiate litigation or other proceedings against third parties to enforce the Company's patent rights; - The Company may initiate litigation or other proceedings against third parties to seek to invalidate the patents held by such third parties or to obtain a judgment that the Company's products or processes due not infringe such third parties' patents; - If the Company's competitors file patent applications claiming technology also claimed by the Company, the Company may participate in interference or opposition proceedings to determine the priority of inventions; - If third parties initiate litigation claiming that the Company's processes or products infringe such third parties' patent or intellectual property rights, the Company will need to defend against such proceedings; and 87

- An adverse outcome in any litigation or other proceeding could subject the Company to significant liabilities to third parties and require that the Company cease using the technology that is at issue or to license the technology from third parties. The Company may not be able to obtain any required license on commercially acceptable terms or at all. The cost of any patent litigation or other proceeding, even if resolved in the Company's favor, could be substantial. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on the Company's ability to compete in the marketplace. Patent litigation and other proceedings may also consume significant management time. THE COMPANY FACES SIGNIFICANT COMPETITION, WHICH MAY RESULT IN OTHERS DISCOVERING, DEVELOPING OR COMMERCIALIZING PRODUCTS BEFORE OR MORE SUCCESSFULLY THAN THE COMPANY. The pharmaceutical industry is highly competitive and is affected by new technologies, government regulations, health care legislation, availability of financing, litigation and other factors. Most of the Company's competitors have longer operating histories and greater financial and other resources than the Company. The Company will be concentrating essentially all of its efforts and resources on the development of its proprietary technologies. The success of products incorporating such technologies, if any, will depend, in large part, on the intensity of competition from branded and generic opioid containing products, abuse deterrent and opioid synthesis technologies developed by other companies that compete with the Company's technologies and the relative timing of product approval by the FDA of the Company's products compared to competitive products. 88

THE ASSET PURCHASE AGREEMENT We believe this summary describes the material terms of the asset purchase agreement. However, we recommend that you read carefully the complete agreement for the precise legal terms of the asset purchase agreement and other information that may be important to you. The asset purchase agreement is included in this proxy statement as Appendix I. ASSETS SOLD Subject to and upon the terms and conditions of the asset purchase agreement, we are selling to IVAX substantially all of the assets used in the operation of our Congers, New York facilities. FIRST CLOSING We transferred or licensed the following assets to IVAX at a first closing on March 19, 2004: - All formulae, formulations, specifications, technologies, inventions, assays, quality control and testing methods and procedures, manufacturing processes, registrations, know-how and trade secrets relating to certain Products (as defined herein): - All information, data, documentation, schedules and procedures relating to manufacturing processes, process validation, process qualification, equipment validation, equipment qualification, equipment maintenance, equipment calibration, equipment installation, equipment control parameters, environmental controls, and equipment and process operating information, operating manuals and training materials relating to the operation of: - Our Wells Avenue and Brenner Drive facilities; and - All equipment owned by Par Pharmaceutical, Inc. (the landlord of the Brenner Drive facility) and located at our Brenner Drive facility. - The security deposit and prepaid rent under the lease for our Wells Avenue facility. - All of our rights and obligations under: - the lease for our Wells Avenue facility; - the contract of sale for our Brenner Drive facility; and - certain communications-related service contracts for our Wells Avenue and Brenner Drive facilities.

- Guaifenesin-Pseudoephedrine-Codeine Liquid; - Guaifenesin-Hydrocodone Liquid; - Dextromethorphan-Guaifenesin-Pseudoephedrine Liquid; - Dextromethorphan-Guaifenesin Liquid; - Dextromethorphan-Guaifenesin-Pyrilamine Liquid; and - Pseudoephedrine-Dextromethorphan-Chlorpheniramine Liquid. - All documentation pertaining to the validation, approval, analysis, manufacture, marketing or distribution of the Products. - All formulae, formulations, specifications, technologies, inventions, assays, quality control and testing methods and procedures, manufacturing processes, know-how and trade secrets relating to the Products. - All information, data, documentation, schedules and procedures relating to manufacturing processes, process validation, process qualification, equipment validation, equipment qualification, equipment maintenance, equipment calibration, equipment installation, equipment control parameters, environmental controls, and equipment and process operating information, operating manuals and training materials relating to the Products. ASSUMED LIABILITIES Except for the lease for our Wells Avenue facility, the contract of sale for our Brenner Drive facility and the communications-related service contracts noted above, IVAX will not assume any liabilities in connection with the transaction. CLOSING DATES The first closing occurred on March 19, 2004. The second closing will take place within three business days following shareholder approval of the transaction. CONSIDERATION IVAX will pay us a total of $2.5 million in cash, $2.0 million of which we received at the first closing. At the second closing, IVAX will pay us $500,000, less the amount of any losses incurred by IVAX prior to the second closing and arising out of or resulting from: - any breach of any representation or warranty made by us in the asset purchase agreement or in any related agreement or document; - our failure to perform any covenant or agreement in the asset purchase agreement or any related agreement; - any liabilities and obligations that IVAX has not assumed; - any environmental conditions caused by us at the Wells Avenue or Brenner Drive facilities existing on or before the first closing; - any challenge, suit, action or investigation relating to shareholder approval of the asset sale, this proxy statement or any of the transactions contemplated by the asset purchase agreement or any related agreement; - the business that we conducted at the Wells Avenue and Brenner Drive facilities; and - any fees or expenses that we owe to any brokers or financial advisors in connection with the transactions contemplated by the asset purchase agreement. 90

As of the date of this proxy statement, we do not believe that we will have any obligation to indemnify IVAX for any of the above-described losses. This belief is based on our active negotiation of the representations and warranties in the asset purchase agreement and our related investigations to ascertain the accuracy of these representations and warranties. Future events are, however, difficult to foresee. Therefore, we can give no assurance that the $500,000 payment due to us at the second closing will not be reduced by any obligation that we may have to indemnify IVAX. We believe that the source of the cash that IVAX will use to pay the cash consideration will be from IVAX Corporation's working capital. While we cannot be certain that IVAX will have the necessary cash on hand to pay the amount due to us at the second closing, we believe that it is reasonable to assume that IVAX will have the cash on hand. Our belief is based upon the general business reputation of IVAX and its parent corporation, IVAX Corporation. REPRESENTATIONS AND WARRANTIES REPRESENTATIONS AND WARRANTIES OF THE COMPANY In the asset purchase agreement, we make customary representations and warranties to IVAX, including with respect to the matters set forth below: - Subject to shareholder approval of the asset purchase agreement, there are no conflicts between the asset purchase agreement and our charter documents, our contracts or applicable law. - The manufacturing, labeling and packaging equipment located at the Wells Avenue and Brenner Drive facilities was, when last used by us, in working order, normal wear and tear excepted. - We have good and marketable title to the assets that we are selling to IVAX. - We own the rights to the intellectual property necessary to conduct of the business that we conducted at our Wells Avenue and Brenner Drive facilities.

(2) March 31, 2004 results include gain on sale of assets totaling $1,754,000 and gain on restructuring of debt of $12,401,000. Unaudited pro forma financial information has not been provided as the sale of substantially all of the assets used in the operation of the Congers facilities and the assignment of certain related liabilities will be accounted for as a disposition of assets and the Company's financial statements for the year ended December 31, 2003 reflect the write down of such assets to their estimated net realizable value of approximately $2.0 million. PROPOSAL 5 AMENDMENT TO THE COMPANY'S 1998 STOCK OPTION PLAN On August 26, 2003, the Board of Directors of the Company amended the Company's 1998 Stock Option Plan (the "1998 Plan"), to (a) increase the number of shares available for grant of options under the 1998 Plan from 8,100,000 shares to 12,000,000 shares, (b) permit the grant of non-qualified stock options having an 97

exercise price per share which is less than the fair market value of the Company's Common Stock, and (c) set a limit of 5,500,000 option awards that may be granted to one individual in any calendar year. On May 5, 2004 the Board of Directors of the Company further amended the 1998 Plan to (i) further increase the number of shares available for grant of options under the 1998 Plan from 12,000,000 to 20,000,000 shares, and (ii) increase the limit on option awards that may be granted to one individual in any calendar year to 8,750,000 shares. A copy of the 1998 Plan, as amended, is set forth in Appendix F to this Proxy Statement. The amendment to the 1998 Plan will not become effective unless it is approved by the holders of record of a majority of the Company's voting securities. The 1998 Plan allows for the grant of stock options to employees, officers, and consultants of the Company. Approximately 23 employees, officers and directors were eligible to participate in the 1998 Plan as of June 1, 2004. Except for the amendments adopted by the Board on August 26, 2003 and May 5, 2004 as described above, the 1998 Plan remains unchanged. The 1998 Plan is intended to assist the Company in securing and retaining key employees and directors by allowing them to participate in the ownership and growth of the Company through the grant of incentive stock options, as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), or non-qualified stock options to which Section 422 of the Code does not apply (collectively, the "Options"). The granting of Options will serve as partial consideration for and give key employees, directors and consultants an additional inducement to, remain in the service of the Company and will provide them with an increased incentive to work for the Company's success. The Company currently maintains a 1995 Stock Option Plan. See "Compensation of Executive Officers and Directors -- Stock Option Plans." As of June 1, 2004, options to purchase an aggregate of 838,388 shares have been granted under the Company's 1995 Stock Option Plan, of which Options for 140,460 shares had been exercised. As of June 1, 2004, 111,612 shares remained available for issuance under the 1995 Stock Option Plan. The Board of Directors believes that it would be in the best interests of the Company for the shareholders to ratify the amendment to the 1998 Plan to (a) increase the number of shares available for the grant of Options under the 1998 Plan from 8,100,000 to 20,000,000 shares, (b) permit the grant of non-qualified stock options having an exercise price per share which is less than the fair market value of the Company's Common Stock, and (c) set a limit of 8,750,000 option awards that may be granted to one individual in any calendar year. The Board of Directors believes that it is in the best interests of the Company to assure that a sufficient reserve of Common Stock is available to continue to implement a comprehensive equity incentive program for the Company. This will provide a meaningful opportunity for the Company's officers, employees and non- employee Board members and other such parties to acquire a substantial proprietary interest in the enterprise and thereby encourage such individuals to remain in the Company's service and more closely align their interests with those of the Company's shareholders. In addition, the grant of stock options can be made without the expenditure of the Company's cash or other liquid resources, which are being preserved for the development of the Company's opioid API Technologies and ADF Technology. On March 9, 2004 and March 30, 2004, the Stock Option Committee of the Board of Directors approved the commitment to issue stock options exercisable for an aggregate of 13,175,145 shares of Common Stock. The grant of such stock options is contingent on the receipt of shareholder approval to amend the 1998 Plan as provided in this Proposal 5 (the "Contingent Options"). Upon grant, all of the Contingent Options will have an exercise price of $0.13 per share, which exercise price is less than the fair market value of the Company's Common Stock on the date of the Stock Option Committee's commitment to issue such options. In the event shareholders do not approve this Proposal 5 and Proposal 2, the Contingent Options will not be granted. As of June 1, 2004, options to purchase an aggregate of 2,691,342 shares of Common Stock have been granted under the 1998 Plan, of which 22,000 shares had been exercised. Assuming the receipt of shareholder approval of the amendment to the 1998 Plan, and after giving effect to the grant of the Contingent Options following such approval, 4,133,513 shares will remain available for the grant of Options under the 1998 Plan. In addition to the increase in the number of shares available for the grant of Options under the 1998 Plan, the 1998 Plan has been amended to permit the grant of non-qualified stock options at an exercise price per share which is less than the fair market value of the Company's Common Stock on the date of grant. Prior to 98

the Board's amendment, the 1998 Plan provided that an Option must have an exercise price no less than the fair market value of the Company's Common Stock on the date of grant. In adopting the amendment to the 1998 Plan, the Board determined that the additional flexibility afforded by the ability to grant Options at less than fair market value would assist the Company in attracting and retaining key employees, which will enhance long-term shareholder value. Additionally, the grant of non-qualified stock options to employees at a discount to fair market value would serve, in part, to offset the substantial dilution to previously granted employee options as a result of the completion of the Company's offering of its 2002 Debentures and 2004 Debentures. As described below under the caption "2003 and 2004 Stock Option Commitments", the Stock Option Committee has approved the commitment to issue the Contingent Options be exercisable for an aggregate of 13,175,145 shares. Upon grant, all of the Contingent Options will have an exercise price less than the fair market value of the Company's Common Stock on the date of the Stock Option Committee's commitment to issue such options. Except for grant of the Contingent Options described above and under the caption "2003 and 2004 Stock Option Commitments" below, the Board of Directors does not contemplate granting non-qualified stock options in the future having an exercise price less than fair market value. Any such discounted Options granted in the future would be of considerably smaller magnitude and be made on an isolated basis. In addition to the increase in the number of shares available under the 1998 Plan and the discretion to grant non-qualified stock options having an exercise prior less than the fair market value of the Company's Common Stock, the Board amended the 1998 Plan to set a limit of 8,750,000 Option awards that may be made to an individual in any calendar year. Prior to the Board's amendment, the 1998 Plan contained no limit on the number of Options that the Board or Stock Option Committee may grant to any employee in any year or during the term of the 1998 Plan. The annual option limit of 8,750,000 Options to any individual under the 1998 Plan is included to qualify the 1998 Plan under Section 162(m) of the Internal Revenue Code. Section 162(m) of the Internal Revenue Code precludes a public company from taking a deduction for annual compensation in excess of $1,000,000 paid to its Chief Executive Officer or any of its four other highest-paid officers. However, compensation that qualifies under Section 162(m) of the Internal Revenue Code as "performance-based" is specifically exempted from the deduction limit. Based on Section 162(m) and the regulations promulgated under such section, the Company's ability to deduct compensation expense generated in connection with the exercise of stock options should not be limited for stock options granted at fair market value, provided the 1998 Plan contains the annual limit proposed in this Proposal 5. The inclusion in the 1998 Plan of the limit of 8,750,000 Options to an individual within any calendar year will be used by the Company to determine whether the compensation realized by an individual would be included in the amount in determining whether an executive's annual compensation exceeds the $1,000,000 deductibility limitation under Section 162(m) of the Internal Revenue Code. The exercise of Options having a fair market value exercise price which have been granted within the limitations provided in the amended 1998 Plan are not counted toward the deductibility limitation. The annual limit provided in the amended 1998 Plan of 8,750,000 Options is arbitrary and the number is not specified in the Internal Revenue Code. The Board of Directors believes, however, that the amount provides sufficient flexibility to address the Company's compensation objectives while allowing the Company to take advantage of the tax benefits of compensation paid to an executive. The following discussion of the principal features and effects of the 1998 Plan, as amended, is qualified in its entirety by reference to the text of the 1998 Plan, as amended, set forth in Appendix F attached hereto. ADMINISTRATION The 1998 Plan has been administered by the Stock Option Committee of the Board of Directors (the "Stock Option Committee"), consisting of not less than two members of the Board of Directors of the Company appointed by the Board. Each member of the Stock Option Committee was a "non-employee director" as defined in Rule 16b-3 of the Securities Exchange Act of 1934, as amended. The Stock Option Committee selected the employees, directors and consultants that were granted Options under the 1998 Plan and, subject to the provisions of the 1998 Plan, determined the terms and conditions and number of shares subject to each Option. During 2003, the Stock Option Committee was comprised of Messrs. Skelly, Sumner, 99

and Smith. Effective as of the date of the Meeting, the Stock Option Committee will be dissolved and the Board of Directors shall administer the 1998 Plan and perform the functions previously conducted by the Stock Option Committee. SHARES SUBJECT TO THE 1998 PLAN The 1998 Plan authorizes the granting of either incentive stock options or non-qualified stock options to purchase in the aggregate up to 8,100,000 shares of the Company's Common Stock. The amendments to the 1998 Plan approved by the Board on August 26, 2003 and May 5, 2004, subject to shareholder approval as provided in this Proposal 5, will increase the number of shares available for grant of Options under the 1998 Plan to 20,000,000 shares. The shares available for issuance will be increased or decreased according to any reclassification, recapitalization, stock split, stock dividend or other such subdivision or combination of the Company's Common Stock. Shares of the Company's Common Stock subject to unexercised Options that expire or are terminated prior to the end of the period during which Options may be granted under the 1998 Plan will be restored to the number of shares available for issuance under the 1998 Plan. Assuming the receipt of shareholder approval of this Proposal 5 and Proposal 2, after giving effect to the grant of the Contingent Options following receipt of shareholder approval of the amended 1998 Plan, 4,133,513 shares of common stock will remain available for the grant of Options under the 1998 Plan. ELIGIBILITY Any employee of the Company or any subsidiary of the Company shall be eligible to receive incentive stock options and non-qualified stock options under the 1998 Plan. Non-qualified stock options may be granted to employees as well as non-employee directors and consultants of the Company under the 1998 Plan as determined by the Board or the Stock Option Committee. Any person who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options. Each grant of an Option shall be evidenced by an Option Agreement, and each Option Agreement shall (i) specify whether the Option is an incentive stock option or a non-qualified stock option and (ii) incorporate such other terms and conditions as the Board of Directors or the Stock Option Committee acting in its absolute discretion deems consistent with the terms of the 1998 Plan, including, without limitation, a restriction on the number of shares of Common Stock subject to the Option which first become exercisable during any calendar year. To the extent that the aggregate fair market value of the Common Stock of the Company underlying a grant of incentive stock options (determined as of the date such an incentive stock option is granted), which first become exercisable in any calendar year, exceeds $100,000, such Options shall be treated as non-qualified stock options. This $100,000 limitation shall be administered in accordance with the rules under Section 422(d) of the Code. The amendment to the 1998 Plan approved by the Board on August 26, 2003, subject to shareholder approval as provided in this Proposal 5, will set a limit of 8,750,000 shares that may be subject to an Option award that may be made to an individual in any calendar year. EXERCISE PRICE OF OPTIONS Upon the grant of an Option to an employee, director or consultant of the Company, the Stock Option Committee will fix the number of shares of the Company's Common Stock that the optionee may purchase upon exercise of the Option and the price at which the shares may be purchased. The Option price for incentive stock options shall not be less than the fair market value of the Common Stock at the time the Option is granted, except that the Option price shall be at least 110% of the fair market value where the Option is granted to an employee who owns more than 10% of the voting power of all classes of stock of the Company or any parent or subsidiary. Under the terms of the 1998 Plan, the aggregate fair market value of the stock (determined at the time the Option is granted) with respect to which incentive stock options are exercisable for the first time by such individual during any calendar year shall not exceed $100,000. The Option price for non-qualified stock options granted under the 1998 Plan may not be less than the fair market 100

value of the Company's Common Stock. The amendment to the 1998 Plan approved by the Board on August 26, 2003, subject to shareholder approval as provided in this Proposal 5, permits the Stock Option Committee to grant non-qualified stock options at a per share price less than the fair market value of the Company's Common Stock on the date of grant. "Fair market value" is determined by the Stock Option Committee based on the average of the closing bid and asked price of the Common Stock on the OTC Bulletin Board. On June 1, 2004, the average of the closing bid and asked price of the Company's Common Stock, as reported by the OTC Bulletin Board, was approximately $0.49. TERMS All Options available to be granted under the 1998 Plan must be granted by April 16, 2008. The Stock Option Committee will determine the actual term of the Options but no Option will be exercisable after the expiration of 10 years from the date of grant. No incentive stock option granted to an employee who owns more than 10% of the combined voting power of all the outstanding classes of stock in the Company may be exercised after five years from the date of grant. The Options granted pursuant to the 1998 Plan shall not be transferable except (i) by will or the laws of descent and distribution and (ii) non-qualified options may be transferred in limited circumstances to immediate family members and family limited partnerships, with the consent of the Stock Option Committee. EXERCISE OF OPTIONS Options granted to employees, directors or consultants under the 1998 Plan may be exercised during the optionee's lifetime only by the optionee during his employment or service with the Company or for a period not exceeding one year if the optionee ceased employment or service as a director or consultant because of permanent or total disability within the meaning of Section 22(e)(3) of the Code. Options may be exercised by the optionee's estate, or by any person who acquired the right to exercise such Option by bequest or inheritance from the optionee for a period of twelve months from the date of the optionee's death. If such Option shall by its terms expire sooner, such Option shall not be extended as a result of the optionee's death. The consideration to be paid to the Company upon exercise of an Option may consist of any combination of cash, checks, promissory notes, shares of Common Stock, and/or any other forms of consideration permitted under New York law and approved by the Stock Option Committee and/or the Board of Directors. With the exception of the consideration received by the Company upon the exercise of Options granted under the 1998 Plan, no consideration is received by the Company for the granting or extension of any Options. FEDERAL INCOME TAX CONSEQUENCES RELATING TO INCENTIVE STOCK OPTIONS Certain Options granted under the 1998 Plan are intended to qualify as "incentive stock options" within the meaning of Section 422 of the Code. Set forth below is a discussion of all relevant Federal income tax consequences to participants and the Company of incentive stock options granted under the 1998 Plan. An employee to whom an incentive stock option is granted pursuant to the 1998 Plan will not recognize any compensation income at the time an incentive stock option is granted or at the time an incentive stock option is exercised. In the year of exercise, however, the amount by which the fair market value of the Common Stock exceeds the Option price will be included as a positive adjustment in the calculation of the optionee's alternative minimum taxable income in the year of exercise. The "alternative minimum tax" imposed on individual taxpayers is generally equal to the amount by which 28% (26% of alternative minimum tax income below certain amounts) of the individual's alternative minimum tax income (reduced by certain exemption amounts) exceeds his or her regular income tax liability for the year. If the optionee incurs minimum tax in the year of exercise, however, he should qualify for the credit for prior year maximum tax liability in the first future year he has regular tax liability. In general, neither the exercise of an incentive stock option nor the sale of any Common Stock acquired under the incentive stock option will have any tax consequences to the Company. However, the Company will generally be entitled to a business-expense deduction with respect to any ordinary compensation income 101

recognized by an optionee, including as a result of a disqualifying disposition of the Common Stock acquired under the incentive stock option (discussed in the following paragraph), at the same time that the optionee recognizes ordinary income compensation. In order to obtain incentive stock option treatment for Federal income tax purposes upon the subsequent sale (or other disposition) by the optionee of the shares of Common Stock received upon exercise of the Option, the sale (or other disposition) must not occur within two years from the date the Option was granted nor within one year after the issuance of such shares upon exercise of the Option (the "incentive stock option holding period requirements"). If the incentive stock option holding period requirements are satisfied, on the subsequent sale (or other disposition) by the optionee of the shares of Common Stock received upon the exercise of an Option, the optionee generally will recognize income from the sale of a capital asset equal to the difference, if any, between the proceeds realized from the sale (or other disposition) and the amount paid as the exercise price of the Option. Alternatively, if the incentive stock option holding period requirements are not satisfied, on the subsequent sale (or other disposition) by the optionee of the shares of Common Stock received upon the exercise of the Option, the optionee generally will recognize income taxable as compensation (and the Company will recognize a compensation deduction) in an amount equal to the lesser of (a) the difference, if any, between the fair market value of the shares on the date of exercise and the amount paid as the exercise price of the Option and (b) the difference, if any, between the proceeds realized from the sale or other disposition and the amount paid as the exercise price of the Option. Any additional gain realized on such sale or disposition (in addition to the compensation income referred to above) would give rise to income from the sale of a capital asset and taxed accordingly. FEDERAL INCOME TAX CONSEQUENCES RELATING TO NON-QUALIFIED STOCK OPTIONS The non-qualified stock options which may be granted under the 1998 Plan are not intended to qualify as incentive stock options within the meaning of Section 422 of the Code. Set forth below is a discussion of all relevant Federal income tax consequences to participants and the Company of non-qualified stock options granted under the 1998 Plan. An individual to whom a non-qualified stock option is granted pursuant to the 1998 Plan will generally not recognize any compensation income, and the Company will not realize any compensation deduction, at the time the non-qualified stock option is granted. In the year of exercise, however, the optionee generally will realize income taxable as compensation (and the Company will realize a compensation deduction) in an amount equal to the difference, if any, between the fair market value of the shares on the date of exercise and the amount paid as the exercise price of the Option. The tax basis of the shares of Common Stock received by the optionee upon exercise will be equal to the amount paid as the exercise price plus the amount, if any, includable in his gross income as compensation income. The holding period for the shares will commence on the date of exercise. On the subsequent sale (or other disposition) by the optionee of the shares of Common Stock received upon the exercise of the Option, any gain realized on such sale or disposition would give rise to income from the sale of a capital asset and taxed accordingly. Section 162(m) of the Internal Revenue Code generally disallows a public corporation's tax deduction for compensation to its Chief Executive Officer or any of its four other most highly compensated officers in excess of $1,000,000 within a year. Compensation that qualifies as "performance-based compensation" is excluded from the $1,000,000 deductibility cap, and therefore remains fully deductible by the corporation that pays it. The Company's 1998 Plan has been amended by the Board of Directors and, subject to your approval of this Proposal 5, will set a limit of 8,750,000. Options that may be granted to an individual in any calendar year. If the amended 1998 Plan is adopted by the Company's shareholders, stock options granted to the Company's Chief Executive Officer and next four highest compensated officers having an exercise price at least equal to fair market value will be deemed "performance based" as provided in Section 162(m) of the Internal Revenue Code and not subject to the $1,000,000 deductibility cap. With respect to a stock options granted to the Company's Chief Executive Officer and next four highest compensated officers having an exercise price less than the fair market value of the Company's Common Stock at the date of grant, the 102

compensation expense resulting from the exercise of any such stock options will not qualify as a "performance based" compensation under the requirements of Section 162(m) of the Internal Revenue Code and will be subject to the $1,000,000 deductibility cap. PREVIOUSLY GRANTED OPTIONS As of December 31, 2002, the Company had granted options to purchase an aggregate of 3,193,617 shares of Common Stock under the 1998 Plan at a weighted average exercise price of $1.97 per share. Of such options, 2,410,034 shares and 783,583 shares were vested and unvested, respectively, and 22,000 Options granted under the 1998 Plan had been exercised. The following table sets forth information concerning option grants made during fiscal 2002 with respect to (i) each executive officer; (ii) all current executive officers as a group; (iii) each nominee for election as a Director; (iv) all current Directors who are not executive officers as a group; (v) each person who has received or is to receive 5% of such Options or rights; and (vi) all employees, including all current officers who are not executive officers, as a group:

the commitment adopted August 26, 2003 to increase the Stock Options subject to such commitment from 5,500,000 shares to 8,750,000 (collectively, the "Contingent Options"). Upon grant, the Contingent Options will provide for an exercise price of $0.13 per share. Prior to the receipt of shareholder approval to the amendment to the 1998 Plan as provided in this Proposal 5, the 1998 Plan did not provide for the grant of stock options at less than the trading price of the Company's Common Stock on the date of grant. As such the grant of the Contingent Options is subject to the receipt of shareholder approval to amend the 1998 Plan as provided in this Proposal 5. In the event shareholders do not approve this Proposal 5, the Contingent Options will be not be granted. The following table sets forth information concerning the Contingent Options with respect to (i) each executive officer; (ii) all current executive officers as a group; (iii) each nominee for election as a Director; (iv) all current Directors who are not executive officers as a group; (v) each person who has received or is to receive 5% of such options or rights; and (vi) all employees, including all current officers who are not executive officers, as a group. Except for the Contingent Options, there have been no commitments for or grants of Stock Options in 2003 or year-to-date 2004.

AMENDMENTS AND DISCONTINUANCE OF THE 1998 PLAN The 1998 Plan can be amended, suspended or terminated at any time by action of the Company's Board of Directors, except that no amendment to the 1998 Plan can be made without prior shareholder approval where such amendment would result in (i) any material increase in the total number of shares of Common Stock subject to the 1998 Plan, (ii) any change in the class of eligible participants for Options under the 1998 Plan, (iii) any material increase in the benefits accruing to participants under the 1998 Plan, or (iv) shareholder approval being required for continued compliance with Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended. VOTE REQUIRED The affirmative vote of the holders of a majority of the Company's voting securities is required for the approval of the amendment to the 1998 Plan. 104

RECOMMENDATION OF THE BOARD OF DIRECTORS The Board of Directors recommends a vote FOR the approval of the amendment to the 1998 Plan. PROPOSAL 6 RATIFICATION OF APPOINTMENT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS There will also be submitted for consideration and voting at the Meeting, the ratification of the appointment by the Company's Board of Directors of Grant Thornton LLP as independent certified public accountants for the purpose of auditing and reporting upon the financial statements of the Company for the fiscal year ending December 31, 2004. The Board of Directors of the Company selected and approved the accounting firm of Grant Thornton LLP as independent certified public accountants to audit and report upon the Company's financial statements for the fiscal years ended December 31, 1984 through and including 2003. Grant Thornton LLP has no direct or indirect financial interest in the Company. Representatives of Grant Thornton LLP are expected to be present at the Meeting, and they will be afforded an opportunity to make a statement at the Meeting if they desire to do so. It is also expected that such representatives will be available at the Meeting to respond to appropriate questions by shareholders. AUDIT FEES The aggregate fees billed for professional services rendered by the Company's principal accountant for the audit of the Company's annual financial statements for the fiscal years ended December 31, 2002 and December 31, 2003, and for the reviews of the financial statements included in the Company's Quarterly Reports on Form 10-Q for such fiscal years, were$176,000 and $150,623, respectively, all of which were attributable to Grant Thornton LLP. AUDIT-RELATED FEES The aggregate fees billed for professional services rendered by the Company's principal accountant and which are reasonably related to the performance of the audit or review of the Company's financial statements and which are not reported above under the caption "Audit Fees" for each of the fiscal years ended December 31, 2002 and December 31, 2003, were $14,180 and $36,620, respectively, all of which were attributable to Grant Thornton LLP. These fees relate to services provided in connection with the audit of the Company's 401(k) and profit sharing plan. TAX FEES The aggregate fees bills for professional services rendered by the Company's principal accountant for tax compliance, tax advice and tax planning for the fiscal years ended December 31, 2002 and December 31, 2003 were $54,000 and $51,236,respectively, all of which were attributable to Grant Thornton LLP. These services related to the preparation of various state and Federal tax returns. ALL OTHER FEES There were no fees billed for professional services rendered by the Company's principal accountant for products and services provided, other than those described above under the captions "Audit Fees", "Audit-Related Fees" and "Tax Fees", for the fiscal years ended December 31, 2002 and December 31, 2003. AUDIT COMMITTEE'S PRE-APPROVAL POLICIES AND PROCEDURES Consistent with policies of the Commission regarding auditor independence and the Audit Committee Charter, the Audit Committee has the responsibility for appointing, setting compensation and overseeing the work of the independent auditor. The Audit Committee's policy is to pre-approve all audit and permissible non-audit services provided by the independent auditor. Pre-approval is detailed as to the particular service or 105

category of services and is generally subject to a specific budget. The Audit Committee may also pre-approve particular services on a case-by-case basis. In assessing requests for services by the independent auditor, the Audit Committee considers whether such services are consistent with the auditor's independence, whether the independent auditor is likely to provide the most effective and efficient service based upon their familiarity with the Company, and whether the service could enhance the Company's ability to manage or control risk or improve audit quality. All of the audit-related, tax and other services provided by Grant Thornton LLP in fiscal year 2003 and related fees (as described in the captions above) were approved in advance by the Audit Committee. AUDIT COMMITTEE REPORT The Audit Committee of the Board of Directors of the Company (the "Audit Committee") was composed of four directors during 2003 and operates under a written charter adopted by the Board of Directors. The written charter is attached to this Proxy Statement as Appendix A. Management is responsible for the Company's internal control and financial reporting process. The Company's independent public accountants are responsible for performing an independent audit of the Company's consolidated financial statements in accordance with generally accepted auditing standards and to issue a report thereon. The Audit Committee's responsibility is to monitor and oversee these processes. In this context, the Audit Committee has met and held discussions with Management and the Company's independent public accountants. Management represented to the Audit Committee that the Company's consolidated financial statements were prepared in accordance with generally accepted accounting principles, and the Audit Committee has reviewed and discussed the consolidated financial statements with Management and the Company's independent public accountants. The Audit Committee discussed with the independent public accountants matters required to be discussed by Statement of Auditing Standards Numbers 90 and 61 (communication with Audit Committees). The Company's independent public accountants also provided to the Audit Committee the written disclosures required by Independence Standard No. 1 (independent discussions with Audit Committee), and the Audit Committee discussed with the independent public accountants that firm's independence. The Audit Committee has also considered whether the independent auditors' provision of non-audit services to the Company is compatible with the auditor's independence.

APPENDIX B NEW YORK BUSINESS CORPORATION LAW SECTION 623 PROCEDURE TO ENFORCE SHAREHOLDER'S RIGHT TO RECEIVE PAYMENT FOR SHARES (a) A shareholder intending to enforce his right under a section of this chapter to receive payment for his shares if the proposed corporate action referred to therein is taken shall file with the corporation, before the meeting of shareholders at which the action is submitted to a vote, or at such meeting but before the vote, written objection to the action. The objection shall include a notice of his election to dissent, his name and residence address, the number and classes of shares as to which he dissents and a demand for payment of the fair value of his shares if the action is taken. Such objection is not required from any shareholder to whom the corporation did not give notice of such meeting in accordance with this chapter or where the proposed action is authorized by written consent of shareholders without a meeting. (b) Within ten days after the shareholders' authorization date, which term as used in this section means the date on which the shareholders' vote authorizing such action was taken, or the date on which such consent without a meeting was obtained from the requisite shareholders, the corporation shall give written notice of such authorization or consent by registered mail to each shareholder who filed written objection or from whom written objection was not required, excepting any shareholder who voted for or consented in writing to the proposed action and who thereby is deemed to have elected not to enforce his right to receive payment for his shares. (c) Within twenty days after the giving of notice to him, any shareholder from whom written objection was not required and who elects to dissent shall file with the corporation a written notice of such election, stating his name and residence address, the number and classes of shares as to which he dissents and a demand for payment of the fair value of his shares. Any shareholder who elects to dissent from a merger under section 905 (Merger of subsidiary corporation) or paragraph (c) of section 907 (Merger or consolidation of domestic and foreign corporations) or from a share exchange under paragraph (g) of section 913 (Share exchanges) shall file a written notice of such election to dissent within twenty days after the giving to him of a copy of the plan of merger or exchange or an outline of the material features thereof under section 905 or 913. (d) A shareholder may not dissent as to less than all of the shares, as to which he has a right to dissent, held by him of record, that he owns beneficially. A nominee or fiduciary may not dissent on behalf of any beneficial owner as to less than all of the shares of such owner, as to which such nominee or fiduciary has a right to dissent, held of record by such nominee or fiduciary. (e) Upon consummation of the corporate action, the shareholder shall cease to have any of the rights of a shareholder except the right to be paid the fair value of his shares and any other rights under this section. A notice of election may be withdrawn by the shareholder at any time prior to his acceptance in writing of an offer made by the corporation, as provided in paragraph (g), but in no case later than sixty days from the date of consummation of the corporate action except that if the corporation fails to make a timely offer, as provided in paragraph (g), the time for withdrawing a notice of election shall be extended until sixty days from the date an offer is made. Upon expiration of such time, withdrawal of a notice of election shall require the written consent of the corporation. In order to be effective, withdrawal of a notice of election must be accompanied by the return to the corporation of any advance payment made to the shareholder as provided in paragraph (g). If a notice of election is withdrawn, or the corporate action is rescinded, or a court shall determine that the shareholder is not entitled to receive payment for his shares, or the shareholder shall otherwise lose his dissenter's rights, he shall not have the right to receive payment for his shares and he shall be reinstated to all his rights as a shareholder as of the consummation of the corporate action, including any intervening preemptive rights and the right to payment of any intervening dividend or other distribution or, if any such rights have expired or any such dividend or distribution other than in cash has been completed, in lieu thereof, at the election of the corporation, the fair value thereof in cash as determined by the board as of the time of B-1

such expiration or completion, but without prejudice otherwise to any corporate proceedings that may have been taken in the interim. (f) At the time of filing the notice of election to dissent or within one month thereafter the shareholder of shares represented by certificates shall submit the certificates representing his shares to the corporation, or to its transfer agent, which shall forthwith note conspicuously thereon that a notice of election has been filed and shall return the certificates to the shareholder or other person who submitted them on his behalf. Any shareholder of shares represented by certificates who fails to submit his certificates for such notation as herein specified shall, at the option of the corporation exercised by written notice to him within forty-five days from the date of filing of such notice of election to dissent, lose his dissenter's rights unless a court, for good cause shown, shall otherwise direct. Upon transfer of a certificate bearing such notation, each new certificate issued therefor shall bear a similar notation together with the name of the original dissenting holder of the shares and a transferee shall acquire no rights in the corporation except those which the original dissenting shareholder had at the time of the transfer. (g) Within fifteen days after the expiration of the period within which shareholders may file their notices of election to dissent, or within fifteen days after the proposed corporate action is consummated, whichever is later (but in no case later than ninety days from the shareholders' authorization date), the corporation or, in the case of a merger or consolidation, the surviving or new corporation, shall make a written offer by registered mail to each shareholder who has filed such notice of election to pay for his shares at a specified price which the corporation considers to be their fair value. Such offer shall be accompanied by a statement setting forth the aggregate number of shares with respect to which notices of election to dissent have been received and the aggregate number of holders of such shares. If the corporate action has been consummated, such offer shall also be accompanied by (1) advance payment to each such shareholder who has submitted the certificates representing his shares to the corporation, as provided in paragraph (f), of an amount equal to eighty percent of the amount of such offer, or (2) as to each shareholder who has not yet submitted his certificates a statement that advance payment to him of an amount equal to eighty percent of the amount of such offer will be made by the corporation promptly upon submission of his certificates. If the corporate action has not been consummated at the time of the making of the offer, such advance payment or statement as to advance payment shall be sent to each shareholder entitled thereto forthwith upon consummation of the corporate action. Every advance payment or statement as to advance payment shall include advice to the shareholder to the effect that acceptance of such payment does not constitute a waiver of any dissenters' rights. If the corporate action has not been consummated upon the expiration of the ninety day period after the shareholders' authorization date, the offer may be conditioned upon the consummation of such action. Such offer shall be made at the same price per share to all dissenting shareholders of the same class, or if divided into series, of the same series and shall be accompanied by a balance sheet of the corporation whose shares the dissenting shareholder holds as of the latest available date, which shall not be earlier than twelve months before the making of such offer, and a profit and loss statement or statements for not less than a twelve month period ended on the date of such balance sheet or, if the corporation was not in existence throughout such twelve month period, for the portion thereof during which it was in existence. Notwithstanding the foregoing, the corporation shall not be required to furnish a balance sheet or profit and loss statement or statements to any shareholder to whom such balance sheet or profit and loss statement or statements were previously furnished, nor if in connection with obtaining the shareholders' authorization for or consent to the proposed corporate action the shareholders were furnished with a proxy or information statement, which included financial statements, pursuant to Regulation 14A or Regulation 14C of the United States Securities and Exchange Commission. If within thirty days after the making of such offer, the corporation making the offer and any shareholder agree upon the price to be paid for his shares, payment therefor shall be made within sixty days after the making of such offer or the consummation of the proposed corporate action, whichever is later, upon the surrender of the certificates for any such shares represented by certificates. B-2

(h) The following procedure shall apply if the corporation fails to make such offer within such period of fifteen days, or if it makes the offer and any dissenting shareholder or shareholders fail to agree with it within the period of thirty days thereafter upon the price to be paid for their shares: (1) The corporation shall, within twenty days after the expiration of whichever is applicable of the two periods last mentioned, institute a special proceeding in the supreme court in the judicial district in which the office of the corporation is located to determine the rights of dissenting shareholders and to fix the fair value of their shares. If, in the case of merger or consolidation, the surviving or new corporation is a foreign corporation without an office in this state, such proceeding shall be brought in the county where the office of the domestic corporation, whose shares are to be valued, was located. (2) If the corporation fails to institute such proceeding within such period of twenty days, any dissenting shareholder may institute such proceeding for the same purpose not later than thirty days after the expiration of such twenty day period. If such proceeding is not instituted within such thirty day period, all dissenter's rights shall be lost unless the supreme court, for good cause shown, shall otherwise direct. (3) All dissenting shareholders, excepting those who, as provided in paragraph (g), have agreed with the corporation upon the price to be paid for their shares, shall be made parties to such proceeding, which shall have the effect of an action quasi in rem against their shares. The corporation shall serve a copy of the petition in such proceeding upon each dissenting shareholder who is a resident of this state in the manner provided by law for the service of a summons, and upon each nonresident dissenting shareholder either by registered mail and publication, or in such other manner as is permitted by law. The jurisdiction of the court shall be plenary and exclusive. (4) The court shall determine whether each dissenting shareholder, as to whom the corporation requests the court to make such determination, is entitled to receive payment for his shares. If the corporation does not request any such determination or if the court finds that any dissenting shareholder is so entitled, it shall proceed to fix the value of the shares, which, for the purposes of this section, shall be the fair value as of the close of business on the day prior to the shareholders' authorization date. In fixing the fair value of the shares, the court shall consider the nature of the transaction giving rise to the shareholder's right to receive payment for shares and its effects on the corporation and its shareholders, the concepts and methods then customary in the relevant securities and financial markets for determining fair value of shares of a corporation engaging in a similar transaction under comparable circumstances and all other relevant factors. The court shall determine the fair value of the shares without a jury and without referral to an appraiser or referee. Upon application by the corporation or by any shareholder who is a party to the proceeding, the court may, in its discretion, permit pretrial disclosure, including, but not limited to, disclosure of any expert's reports relating to the fair value of the shares whether or not intended for use at the trial in the proceeding and notwithstanding subdivision (d) of section 3101 of the civil practice law and rules. (5) The final order in the proceeding shall be entered against the corporation in favor of each dissenting shareholder who is a party to the proceeding and is entitled thereto for the value of his shares so determined. (6) The final order shall include an allowance for interest at such rate as the court finds to be equitable, from the date the corporate action was consummated to the date of payment. In determining the rate of interest, the court shall consider all relevant factors, including the rate of interest which the corporation would have had to pay to borrow money during the pendency of the proceeding. If the court finds that the refusal of any shareholder to accept the corporate offer of payment for his shares was arbitrary, vexatious or otherwise not in good faith, no interest shall be allowed to him. (7) Each party to such proceeding shall bear its own costs and expenses, including the fees and expenses of its counsel and of any experts employed by it. Notwithstanding the foregoing, the court may, in its discretion, apportion and assess all or any part of the costs, expenses and fees incurred by the corporation against any or all of the dissenting shareholders who are parties to the proceeding, including B-3

any who have withdrawn their notices of election as provided in paragraph (e), if the court finds that their refusal to accept the corporate offer was arbitrary, vexatious or otherwise not in good faith. The court may, in its discretion, apportion and assess all or any part of the costs, expenses and fees incurred by any or all of the dissenting shareholders who are parties to the proceeding against the corporation if the court finds any of the following: (A) that the fair value of the shares as determined materially exceeds the amount which the corporation offered to pay; (B) that no offer or required advance payment was made by the corporation; (C) that the corporation failed to institute the special proceeding within the period specified therefor; or (D) that the action of the corporation in complying with its obligations as provided in this section was arbitrary, vexatious or otherwise not in good faith. In making any determination as provided in clause (A), the court may consider the dollar amount or the percentage, or both, by which the fair value of the shares as determined exceeds the corporate offer. (8) Within sixty days after final determination of the proceeding, the corporation shall pay to each dissenting shareholder the amount found to be due him, upon surrender of the certificate for any such shares represented by certificates. (i) Shares acquired by the corporation upon the payment of the agreed value therefor or of the amount due under the final order, as provided in this section, shall become treasury shares or be cancelled as provided in section 515 (Reacquired shares), except that, in the case of a merger or consolidation, they may be held and disposed of as the plan of merger or consolidation may otherwise provide. (j) No payment shall be made to a dissenting shareholder under this section at a time when the corporation is insolvent or when such payment would make it insolvent. In such event, the dissenting shareholder shall, at his option: (1) Withdraw his notice of election, which shall in such event be deemed withdrawn with the written consent of the corporation; or (2) Retain his status as a claimant against the corporation and, if it is liquidated, be subordinated to the rights of creditors of the corporation, but have rights superior to the non-dissenting shareholders, and if it is not liquidated, retain his right to be paid for his shares, which right the corporation shall be obliged to satisfy when the restrictions of this paragraph do not apply. (3) The dissenting shareholder shall exercise such option under subparagraph (1) or (2) by written notice filed with the corporation within thirty days after the corporation has given him written notice that payment for his shares cannot be made because of the restrictions of this paragraph. If the dissenting shareholder fails to exercise such option as provided, the corporation shall exercise the option by written notice given to him within twenty days after the expiration of such period of thirty days. (k) The enforcement by a shareholder of his right to receive payment for his shares in the manner provided herein shall exclude the enforcement by such shareholder of any other right to which he might otherwise be entitled by virtue of share ownership, except as provided in paragraph (e), and except that this section shall not exclude the right of such shareholder to bring or maintain an appropriate action to obtain relief on the ground that such corporate action will be or is unlawful or fraudulent as to him. (l) Except as otherwise expressly provided in this section, any notice to be given by a corporation to a shareholder under this section shall be given in the manner provided in section 605 (Notice of meetings of shareholders). (m) This section shall not apply to foreign corporations except as provided in subparagraph (e) (2) of section 907 (Merger or consolidation of domestic and foreign corporations). (Last amended by Ch. 117, L. '86, eff. 9-1-86.) B-4

To effect the foregoing, Article THIRD is hereby amended to read as follows: "THIRD: The Corporation is authorized to issue two classes of stock, to be designated, respectively, "Common Stock" and "Preferred Stock". The total number of shares which the Corporation is authorized to issue is 940,000,000 of which (A) 290,000,000 shares shall be Preferred Stock (the "Preferred"), and (B) 650,000,000 shares shall be Common Stock, $.01 par value (the "Common"). Of the Preferred, 45,000,000 shares shall be designated Series A Convertible Preferred Stock, $.01 par value per share (the "Series A Preferred"), 25,000,000 shares shall be designated Series B Convertible Preferred Stock, $.01 par value per share (the "Series B Preferred"), 70,000,000 shares shall be designated Series C-1 Convertible Preferred Stock, $.01 par value per C-1

The Series C-1 Preferred, Series C-2 Preferred and Series C-3 Preferred are sometimes referred to collectively as the "Series C Preferred". The rights, preferences and privileges of and restrictions on the Series A Preferred, Series B Preferred, Series C Preferred and Common are as follows: SECTION 1. PREFERRED STOCK (a) Voting Rights. Except as otherwise required by law, each share of outstanding Series A Preferred, Series B Preferred and Series C Preferred shall entitle the record holder thereof to vote on each matter submitted to a vote of the stockholders of the Corporation and to have the number of votes equal to the number of whole shares of Common into which such share of Series A Preferred, Series B Preferred or Series C Preferred, as the case may be, is then convertible pursuant to the provisions hereof at the record date for the determination of stockholders entitled to vote on such matters or, if no such record date is established, at the date such vote is taken or any written consent of stockholders becomes effective. Except as otherwise required by law or by this Certificate, the holders of shares of Common, Series A Preferred, Series B Preferred and Series C Preferred shall vote together and not as separate classes. Fractional votes shall not be permitted and any fractional voting rights resulting from the above formula shall be rounded to the nearest whole number (with one-half rounded upwards). (b) Dividends. If any dividend or other distribution payable in cash, securities or other property is declared on the Common (other than in connection with Section 1(c) below), each holder of shares of Preferred on the record date for such dividend or distribution shall be entitled to receive, on the date of payment or distribution of such dividend or other distribution, the same cash, securities or other property which such holder would have received on such record date if such holder was the holder of record of the number of whole shares of Common into which the shares of Preferred then held by such holder are then convertible (with any resulting fractions rounded to the nearest whole share, with one-half rounded up). (c) Liquidation Rights. If the Corporation shall be voluntarily or involuntarily liquidated, dissolved or wound up (each, a "Liquidation Event"): (1) Prior and in preference to any payments or distributions under Sections 1(c)(2), 1(c)(3) and 1(c)(4) below, the holder of each then outstanding share of Series A Preferred shall be entitled to receive, out of the assets of the Corporation legally available for distribution to stockholders, and before any payment or declaration and setting apart for payment of any amount or dividend pursuant to Sections 1(c)(2) or 1(c)(3) below or with respect to the Common or any other junior equity security of the Corporation, the amount (the "Series A Preference") equal to $3.2125 per share (such amount to be adjusted proportionally in the event the Series A Preferred is subdivided into a greater number or combined into a lesser number of shares). If the Corporation shall have insufficient assets and funds to pay such amounts in full to the holders of the Series A Preferred, then all assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series A Preferred in proportion to the preferential amount each such holder is otherwise entitled to receive pursuant to this Section 1(c)(1). (2) After full payment of the distributions under Section 1(c)(1) above, but prior and in preference to any payments or distributions under Sections 1(c)(3) and 1(c)(4) below, the holder of each then outstanding share of Series B Preferred shall be entitled to receive, out of the assets of the Corporation legally available for distribution to stockholders, and before any payment or declaration and setting apart for payment of any amount or dividend pursuant to Section 1(c)(3) below or with respect to the Common or any other junior equity security of the C-2

Corporation, the amount (the "Series B Preference") equal to $.3420 per share (such amount to be adjusted proportionally in the event the Series B Preferred is subdivided into a greater number or combined into a lesser number of shares). If the Corporation shall have insufficient assets and funds to pay such amounts in full to the holders of the Series B Preferred (after payment in full of all amounts pursuant to Section 1(c)(1) above), then all remaining assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series B Preferred in proportion to the preferential amount each such holder is otherwise entitled to receive pursuant to this Section 1(c)(2). (3) After full payment of the distributions under Sections 1(c)(1) and 1(c)(2) above, but prior and in preference to any payments or distributions under Section 1(c)(4) below, the holder of each then outstanding share of Series C Preferred shall be entitled to receive, out of the assets of the Corporation legally available for distribution to stockholders, and before any payment or declaration and setting apart for payment of any amount or dividend with respect to the Common or any other junior equity security of the Corporation, (i) in the case of Series C-1 Preferred, the amount (the "Series C-1 Preference") equal to $.5776 per share, (ii) in the case of Series C-2 Preferred, the amount (the "Series C-2 Preference") equal to $.5993 per share, and (iii) in the case of Series C-3 Preferred, the amount (the "Series C-3 Preference") equal to $.3481 per share, (in each case such amount to be adjusted proportionally in the event the Series C-1 Preferred, Series C-2 Preferred or Series C-3 Preferred, as applicable, is subdivided into a greater number or combined into a lesser number of shares). If the Corporation shall have insufficient assets and funds to pay such amounts in full to the holders of the Series C Preferred (after payment in full of all amounts pursuant to Sections 1(c)(1) and 1(c)(2) above), then all remaining assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series C Preferred in proportion to the preferential amount each such holder is otherwise entitled to receive pursuant to this Section 1(c)(3). (4) After full payment has been made to the holders of Series A Preferred, Series B Preferred and Series C Preferred of the liquidation preferences in Sections 1(c)(1), 1(c)(2) and 1(c)(3), the entire remaining assets and funds, if any, shall be distributed ratably among the holders of Common and the Series A Preferred, in proportion to the number of shares of Common held by them on an as-converted basis; provided, that for purposes of calculating the distribution pursuant to this Section 1(c)(4), and for no other purposes whatsoever, each share of Series A Preferred shall be deemed to be convertible into only 30% of the shares of Common into which it is convertible pursuant to the terms of Section 1(d) below. (5) For purposes of this Section 1(c), unless the holders of a majority of the then outstanding shares of Series A Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) together as a single class, elect otherwise, (i) the consummation of any merger, consolidation or similar transaction or series of related transactions, the result of which is that the holders of the Corporation's capital stock outstanding immediately prior to such transaction own, immediately upon the consummation of such transaction(s), shares of capital stock possessing in the aggregate less than a majority of the voting power of the surviving entity or rights to liquidation distributions of less than 50% of the assets of the surviving entity, (ii) a sale, lease, exclusive license, transfer or other conveyance of all or substantially all of the assets of the Corporation, or (iii) the sale of 50% or more of the Corporation's voting stock in one or more series of transactions, shall (for purposes of the distribution of such securities or other consideration to the holders of Common and Preferred) be treated as a Liquidation Event and shall entitle the holders of Common and Preferred to receive at closing in cash, securities or other property (valued as provided in Section 1(c)(6) below) as specified above and in the order of preference as set forth in this Section 1(c). (6) Whenever the distribution provided in this Section 1(c) shall be payable in property other than cash, subject to the provisions regarding valuation of securities set forth below, the C-3

value of such distribution shall be its fair market value as determined in good faith by the Board of Directors of the Corporation (the "Board"). The holders of a majority of the Series A Preferred will have 10 days from the determination of the valuation of any securities or other property pursuant this Section 1(c) to object to such valuation in writing to the Corporation. In the event of such objection, the Corporation and a majority in interest of the objecting stockholders will in good faith seek a resolution of any disputed valuation. If the Corporation and the objecting investors are unable to agree on a valuation within 5 days of the objection by the holders of the Series A Preferred, the valuation will be determined by an independent third party appraiser jointly selected by the Corporation and the holders of a majority of the then outstanding shares of Series A Preferred, whose written appraised value will be binding on the Corporation and its stockholders. Any distributions pursuant to this Section 1(c) will be delayed until after the delivery of the appraiser's report. Any securities shall be valued as follows: (i) Securities not subject to investment letter or other similar restrictions on free marketability covered by (ii) below: (A) If traded on a securities exchange or through the Nasdaq National Market or the Nasdaq SmallCap Market, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the 30-day period ending three (3) days prior to the date of determination; (B) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the thirty-day period ending three (3) days prior to the date of determination; and (C) If there is no active public market, the value shall be determined by an independent third party appraiser jointly selected by the Corporation and the holders of a majority of the then outstanding shares of Series A Preferred. (ii) The method of valuation of securities subject to investment letter or other restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder's status as an affiliate or former affiliate) shall be to apply an appropriate discount determined in good faith by the Board from the market value determined as above in (A), (B) or (C). (7) The Corporation shall promptly provide to the holders of shares of Preferred such information concerning the terms of any event or transaction specified in Section 1(c)(5) and the value of the assets of the Corporation as may reasonably be determined by the Board. If the transaction is a sale of all or substantially all of the assets of the Corporation, the Corporation will give written notice of such transaction to each holder of Preferred not less than 20 or more than 60 days before the stockholders' meeting called to approve the transaction or, if no stockholders' meeting will be called, not less than 20 or more than 60 days before the date that the transaction is reasonably anticipated to be consummated, and will also notify the holders in writing of the final approval of the transaction. The initial notice will describe the material terms and conditions of the proposed transaction. The Corporation will give the holders of Preferred prompt notice of any material changes to the terms of the proposed transaction. The Corporation will not consummate the proposed transaction sooner than 20 days after the Corporation has given notice of any material changes. By written consent or vote, the holders of a majority of the shares of Series A Preferred outstanding may shorten the notice periods provided in this Section. In the event the requirements of this Section are not complied with, the Corporation will either: (i) cause the closing to be postponed until the requirements of this Section have been complied with; or (ii) cancel the transaction, in which event the rights, preferences, privileges and restrictions of the holders of the Preferred will revert to the rights, preferences, privileges and restrictions existing immediately before the date of the first notice referred to in this Section. C-4

(d) Conversion. (1) Terms of Conversion. (i) Optional Conversion. The holder of each share of Series A Preferred, Series B Preferred and Series C Preferred shall have the right ("Conversion Right"), at such holder's option, to convert such share at any time, without cost, on the terms of this Section 1(d) and at the office of the Corporation or its transfer agent, into the number of fully paid and non-assessable shares of Common that results from dividing (A) in the case of the Series A Preferred, the Series A Preference by the Series A conversion price that is in effect at the time of conversion (the "Series A Conversion Price"), (B) in the case of the Series B Preferred, the Series B Preference by the Series B conversion price that is in effect at the time of conversion (the "Series B Conversion Price"), (C) in the case of the Series C-1 Preferred, the Series C-1 Preference by the Series C-1 conversion price that is in effect at the time of conversion (the "Series C-1 Conversion Price"), (D) in the case of the Series C-2 Preferred, the Series C-2 Preference by the Series C-2 conversion price that is in effect at the time of conversion (the "Series C-2 Conversion Price") and (E) in the case of the Series C-3 Preferred, the Series C-3 Preference by the Series C-3 conversion price that is in effect at the time of conversion (the "Series C-3 Conversion Price"). The initial Series A Conversion Price is equal to $.6425. The initial Series B Conversion Price is equal to the Series B Preference. The initial Series C-1 Conversion Price is equal to the Series C-1 Preference. The initial Series C-2 Conversion Price is equal to the Series C-2 Preference. The initial Series C-3 Conversion Price is equal to the Series C-3 Preference. The Series A Conversion Price, the Series B Conversion Price, the Series C-1 Conversion Price, the Series C-2 Conversion Price and the Series C-3 Conversion Price shall be subject to adjustment from time to time as provided in Section 1(d)(3) below. (ii) Mandatory Conversion. (A) Upon the occurrence of a Qualified Trading Event, each share of Series A Preferred, Series B Preferred and Series C Preferred shall be automatically converted, without cost and on the terms of this Section 1(d), into the number of whole shares of Common into which such share of Series A Preferred, Series B Preferred or Series C Preferred, as the case me be, would be convertible under Section 1(d)(1)(i) above immediately prior to such Qualified Trading Event (with any resulting fractions rounded to the nearest whole share, with one-half rounded up). "Qualified Trading Event" means the first such time that (A) the Common has a closing price of at least $2.80 per share (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares) for thirty consecutive trading days, and (B) the average daily trading value of all shares of Common traded during such thirty consecutive trading day period is at least $1,750,000. For purposes of this test, (x) closing prices shall be determined as the average between the closing bid and ask prices at the close of each trading day (as reported by such exchange or over-the-counter market on which the Common may then be listed or admitted for trading), and (y) the trading value shall be determined by multiplying the number of shares so traded by such day's closing price as determined above. (B) Without limiting subsection (ii)(A) above, each share of Series A Preferred, Series B Preferred and Series C Preferred shall be automatically converted without cost and on the terms of this Section 1(d), into the number of whole shares of Common into which such share of Series A Preferred, Series B Preferred or Series C Preferred, as the case may be, would be convertible under Section 1(d)(1)(i) above upon the receipt of the written consent of the holders of at least 51% of the shares of Series A Preferred. (2) Mechanics of Conversion. (i) Optional Conversion. A holder of any share of Convertible Preferred may exercise the Conversion Right of such share by surrendering the certificate therefor, duly endorsed, at C-5

the office of the Corporation or of any transfer agent for the applicable Preferred, together with a written notice to the Corporation which shall state (A) that such holder elects to convert the same, and (B) the number of shares of Preferred being converted. Thereupon the Corporation shall issue and deliver to the holder of such shares within two (2) business days a certificate or certificates for the number of shares of Common to which such holder shall be entitled. If the certificate evidencing the Preferred being converted shall also evidence shares of Preferred not being converted, then the Corporation shall also deliver to the holder of such certificate within such two (2) business day period a new stock certificate evidencing the Preferred not converted. The conversion of any shares of Preferred shall be deemed to have been made immediately prior to the close of business on the date that the shares to be converted are surrendered to the Corporation, and the person or persons entitled to receive the shares of Common issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common on such date. Any dividends or distributions declared but unpaid at the time of conversion with respect to the Preferred so converted shall be paid to the holder of Common issued upon conversion of the Preferred. If a stockholder notifies the Corporation or its transfer agent in writing that the stockholder's certificate has been lost, stolen or destroyed, and executes an agreement in a form reasonably satisfactory to the Corporation and its transfer agent to indemnify them from any loss incurred in connection with the lost, stolen or destroyed certificates (without requirement of posting any bond), then such actions shall be treated for purposes of this Section as delivery of such lost, stolen or destroyed certificate. (ii) Mandatory Conversion. The Corporation shall give written notice to each holder of a share of Preferred not more than ten (10) days after the occurrence of a Qualified Trading Event or the receipt of the written consent required pursuant to Section 1(d)(1)(ii)(B), as applicable. Following the conversion of such shares, each holder of shares so converted shall, if requested by the Corporation, surrender the certificate therefor at the office of the Corporation or any transfer agent for the applicable Preferred. Upon such surrender, the Corporation shall issue and deliver to each holder a certificate or certificates for the number of shares of Common to which such holder is entitled. The conversion of shares of Preferred shall be effective as of the occurrence of the Qualified Trading Event or upon receipt of the written consent provided in Section 1(d)(1)(ii)(B), as applicable, whether or not the certificates representing such shares of Preferred shall have been surrendered or new certificates representing the shares of Common into which such shares have been converted shall have been issued. Any dividends or distributions declared but unpaid at the time of a mandatory conversion with respect to the Preferred so converted shall be paid upon such mandatory conversion. If a stockholder notifies the Corporation or its transfer agent in writing that the stockholder's certificate has been lost, stolen or destroyed, and executes an agreement in a form reasonably satisfactory to the Corporation and its transfer agent to indemnify them from any loss incurred in connection with the lost, stolen or destroyed certificates (without requirement of posting any bond), then such actions shall be treated for purposes of this Section as delivery of such lost, stolen or destroyed certificate. (3) Adjustment of Conversion Prices. The Series A Conversion Price, the Series B Conversion Price, the Series C-1 Conversion Price, the Series C-2 Conversion Price and the Series C-3 Conversion Price (each a "Conversion Price") and the kind of securities issuable upon the conversion of any share of Series A Preferred, Series B Preferred, Series C-1 Preferred, Series C-2 Preferred and Series C-3 Preferred (collectively, the "Convertible Preferred"), shall be adjusted from time to time after the Filing Date (as defined below) as follows: (i) Subdivision or Combination of Shares. If the Corporation at any time after the date that this Amended and Restated Certificate of Incorporation was filed with the New York Secretary of State ("Filing Date") effects a subdivision or combination of the outstanding Common, the Conversion Price for each share of outstanding Convertible C-6

Preferred shall be decreased, in the case of a subdivision, or increased, in the case of a combination, in the same proportions as the Common is subdivided or combined, in each case effective automatically upon, and simultaneously with, the effectiveness of the subdivision or combination which gives rise to the adjustment. (ii) Stock Dividends. If the Corporation at any time after the Filing Date pays a dividend, or makes any other distribution, to holders of Common payable in shares of Common, or fixes a record date for the determination of holders of Common entitled to receive a dividend or other distribution payable in shares of Common, the Conversion Price for each share of Convertible Preferred shall be decreased by multiplying it by a fraction: (A) the numerator of which shall be the total number of shares of Common outstanding immediately prior to the time of payment of such dividend or distribution; and (B) the denominator of which shall be the total number of shares of Common outstanding immediately after such dividend or distribution, in each case effective automatically as of the date the Corporation shall take a record of the holders its Common for the purpose of receiving such dividend or distribution (or if no such record is taken, as of the effectiveness of such dividend or distribution). (iii) Reclassification, Consolidation or Merger. If at any time after the Filing Date, as a result of (a) a capital reorganization or reclassification (other than a subdivision, combination or dividend which gives rise to an adjustment of a Conversion Price pursuant to clauses (i) or (ii) of this Section 1(d)(3)); or (b) a merger or consolidation of the Corporation with another corporation (whether or not the Corporation is the surviving corporation), the Common issuable upon the conversion of the Convertible Preferred shall be changed into or exchanged for the same or a different number of shares of any class or classes of stock of the Corporation or any other corporation, or other securities convertible into such shares, then, as a part of such reorganization, reclassification, merger or consolidation, appropriate adjustments shall be made in the terms of the Convertible Preferred (or of any securities into which the Convertible Preferred is changed or for which the Convertible Preferred is exchanged), so that: (x) the holders of Convertible Preferred or of such substitute securities shall thereafter be entitled to receive, upon conversion of the Convertible Preferred or of such substitute securities, the kind and amount of shares of stock, other securities, money and property which such holders would have received at the time of such capital reorganization, reclassification, merger, or consolidation, if such holders had converted their Convertible Preferred immediately prior to such capital reorganization, reclassification, merger, or consolidation, and (y) the Convertible Preferred or such substitute securities shall thereafter be adjusted on terms as nearly equivalent as may be practicable to the adjustments theretofore provided in this Section 1(d)(3). No consolidation or merger in which the Corporation is not the surviving corporation shall be consummated unless the surviving corporation shall agree, in writing, to the provisions of this Section 1(d)(3)(iii). The provisions of this Section 1(d)(3)(iii) shall similarly apply to successive capital reorganizations, reclassifications, mergers, and consolidations. (iv) Adjustment upon Certain Issuances. (A) For purposes of this Section 1(d)(3)(iv), "Additional Shares of Common" means all shares of Common issued by the Corporation after the Filing Date other than: (1) shares of Common issued in transactions giving rise to adjustments under Sections 1(d)(3)(i), (ii), or (iii) above; (2) shares of Common issued upon conversion of shares of Convertible Preferred; (3) shares of Common which may be issued in the discretion of the Board to employees or directors of, or consultants or advisors to, strategic partners of the Corporation or any wholly-owned subsidiary of the Corporation, and options or warrants or other rights for the purchase of such shares; (4) options or warrants or other rights outstanding as of the Filing Date or issued under Section 1(d)(3)(iv)(3) above for the purchase of such shares; (5) securities issued pursuant to any anti-dilution rights of the C-7

Convertible Preferred or the warrants outstanding as of the Filing Date; and (6) shares of Common Stock issued in satisfaction of interest on the Corporation's indebtedness for borrowed money, provided the number of shares of Common Stock issuable is calculated based on the average closing bid and asked prices for the Common Stock for the twenty (20) trading days preceding the interest payment. (B) Except as otherwise provided in this Section 1(d)(3)(iv) below, if at any time the Corporation issues or is deemed to issue Additional Shares of Common for a consideration per share less than the Conversion Price in effect for a given share at such issuance or deemed issuance: (1) in the case of the Series A Preferred, the Conversion Price shall be reduced for such share to a price equal to a price determined by dividing: (x) the aggregate consideration received by or deemed to have been received by the Corporation upon such issue, by: (y) the number of shares of Additional Shares of Common issued or deemed to have been issued in such issue; and (2) in the case of the Series B Preferred, Series C-1 Preferred, Series C-2 Preferred or Series C-3 Preferred, the Conversion Price shall be reduced for such share to a price equal to a price determined by dividing: (x) the sum of (a) the product derived by multiplying the Conversion Price in effect for such share immediately prior to such issue times the number of shares of Common (on a fully-diluted basis) outstanding immediately prior to such issue, plus (b) the aggregate consideration received by or deemed to have been received by the Corporation upon such issue; by (y) the sum of (a) the number of shares of Common (on a fully-diluted basis) outstanding immediately prior to such issue, plus (b) the number of shares of Additional Shares of Common issued or deemed to have been issued in such issue; provided, that no adjustment pursuant to this Section 1(d)(3)(iv)(B)(2) shall be made in connection with any issuance or deemed issuance of Additional Shares of Common for a consideration of at least the then applicable Series A Conversion Price. (v) Convertible Securities. (A) "Convertible Securities" means all rights or options for the purchase of, or stock or other securities convertible into, Additional Shares of Common or other Convertible Securities, whenever and each time issued. (B) The "Effective Price" with respect to any Convertible Securities means the result of dividing: (1) the sum of (x) the total consideration, if any, received by the Corporation for the issuance of such Convertible Securities, plus (y) the minimum consideration, if any, payable to the Corporation upon exercise or conversion of such Convertible Securities (assuming that the full amount of securities issuable upon exercise or conversion are issued), plus (z) the minimum consideration, if any, payable to the Corporation upon exercise or conversion of any Convertible Securities issuable upon exercise or conversion of such Convertible Securities, by: (2) the maximum number of Additional Shares of Common issuable upon exercise or conversion of such Convertible Securities or of any Convertible Securities issuable upon exercise or conversion of such Convertible Securities. C-8

(C) If at any time after the Filing Date the Corporation issues or is deemed to issue a Convertible Security with respect to which the Effective Price is less than the Conversion Price for a share of Convertible Preferred in effect at such issuance or deemed issuance, the Conversion Price for such share of Convertible Preferred shall be reduced to the Effective Price. (D) If Convertible Securities by their terms provide, with the passage of time or otherwise (including by operation of the anti-dilution provisions thereof), for any increase or decrease in the consideration payable to the Corporation or decrease or increase in the number of shares of Common issuable upon the exercise, conversion or exchange thereof (or if any such change is made by amending such Convertible Securities), the Conversion Price computed upon the original issue thereof, and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such the rights of conversion or exchange under such Convertible Securities. No readjustment pursuant to this clause (D) shall have the effect of increasing the applicable Conversion Price in effect to an amount which exceeds the lower of (1) the Conversion Price immediately following, and as adjusted to reflect, the Company's issuance of such Convertible Securities (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares), or (2) the Conversion Price that would have resulted from any issuances of Additional Shares of Common or Convertible Securities between the date the Company adjusted the Conversion Price to reflect the issuance of such original Convertible Securities and such readjustment date. (E) If an adjustment has been made under this Section 1(d)(3)(v) as a consequence of any issuance of a Convertible Security, then no further adjustment shall be made under Section 1(d)(3)(iv) above upon the actual issuance of Additional Shares of Common upon the exercise or conversion of such Convertible Securities, or upon the issuance of Convertible Securities issuable upon exercise or conversion of the original Convertible Security. (vi) Valuation of Consideration. For purposes of the operation of Sections 1(d)(3)(iv) and (v) above, the consideration received by the Corporation for any issue or sale of securities shall: (A) to the extent it consists of cash, be computed as the aggregate net amount of cash received by the Corporation; (B) to the extent it consists of property other than cash, be computed at the fair value of that property as determined in good faith by the Board in accordance with the terms of Section 1(c)(6) above; and (C) to the extent Additional Shares of Common or Convertible Securities are issued or sold together with other stock or securities or other assets of the Corporation for a consideration that covers both, be such portion of the consideration so received that may be reasonably determined in good faith by the Board to be allocable to such Additional Shares of Common or Convertible Securities. (vii) Other Action Affecting Common. If at any time the Corporation takes any action affecting its Common which, in the opinion of the Board, would have an adverse effect upon the Conversion Rights of a given share of the Convertible Preferred, the Conversion Price for such share and the kind of securities issuable upon the conversion of such share shall be adjusted in such manner and at such time as the Board may in good faith determine to be equitable in the circumstances. (vii) Notice of Adjustments. Whenever the Conversion Price or the kind of securities issuable upon the conversion of any one of or all of the Convertible Preferred shall be C-9

adjusted pursuant to Section 1(d)(3)(i)-(v) or (vii) above, the Corporation shall make a certificate signed by its Chief Financial Officer, Secretary or Assistant Secretary, setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis on which the Board made any determination hereunder), and the Conversion Price and the kind of securities issuable upon the conversion of such share(s) of the Convertible Preferred after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail postage prepaid) to each holder of Convertible Preferred promptly after each adjustment. (4) Full Consideration. All shares of Common which shall be issued upon the conversion of any Convertible Preferred (which is itself fully paid and non-assessable) will, upon issuance, be fully paid and non-assessable. The Corporation will pay such amounts and will take such other action as may be necessary from time to time so that all shares of Common which shall be issued upon the conversion of any Convertible Preferred will, upon issuance and without cost to the recipient, be free from all pre-emptive rights, taxes, liens and charges with respect to the issue thereof. (5) No Impairment. The Corporation will not, by amendment of its Amended and Restated Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 1(d) and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of any holder of the Convertible Preferred against impairment. The Corporation shall at all times when the Convertible Preferred shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Convertible Preferred, such number of its duly authorized shares of Common as shall from time to time be sufficient to effect the conversion of all outstanding shares of Convertible Preferred. (6) No Reissuance of Preferred. No share of Preferred acquired by the Corporation upon conversion, redemption or purchase shall be reissued and all such shares shall be canceled, retired and eliminated from the shares which the Corporation may be authorized to issue. The Corporation shall take all such corporate action necessary or appropriate to reduce the authorized number of Preferred accordingly. (7) Minimum Conversion Price. Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value of the shares of Common issuable upon conversion of the shares of Convertible Preferred, the Corporation will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and nonassessable shares of Common at such adjusted Conversion Price. SECTION 2. COMMON STOCK (a) Voting Rights. Except as otherwise required by law or by this Certificate, each share of Common shall entitle the holder thereof to one vote on each matter submitted to a vote of the stockholders of the Corporation, and the holders of shares of Common, Series A Preferred, Series B Preferred and Series C Preferred shall vote together and not as separate classes. (b) Dividend Rights. Subject to the dividend rights of the holders of the Preferred set forth in Sections 1(b) and 1(c) above, the holders of the Common shall be entitled to receive, as, when and if declared by the Board, but only out of funds legally available therefor, cash dividends in such amounts as the Board may determine. C-10

(c) Liquidation Rights. In the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, after payment or provision for payment of the debts and other liabilities of the Corporation and the preferential amounts to which the holders of any outstanding shares of Preferred shall be entitled to receive upon dissolution, liquidation, or winding up, the holders of the Common shall be entitled to share on a share for share basis in the remaining assets of the Corporation (together with the holders of Series A Preferred as set forth in Section 1(c)(4) above). (d) Residual Rights. All rights accruing to the outstanding shares of the Corporation not otherwise expressly provided for herein shall be vested in the Common. (d) Article FOURTH of the Certificate of Incorporation, relating to the location of the Corporation's office in New York and its agent for service of process, is hereby amended to read as follows: "FOURTH: The office of the Corporation is to be located in the County of New York, State of New York.

The address to which the Secretary of State shall mail a copy of any such process so served is: Halsey Drug Co., Inc. 616 N. North Court, Suite 120 Palatine, Illinois 60067 Attention: President" (e) Articles SEVENTH, EIGHTH and NINTH, relating to the first directors and the original subscribers for shares of the Corporation are hereby deleted in their entirety. (f) Article TENTH, relating to shareholder preemptive rights, is hereby renumbered as Article SEVENTH. (g) Article ELEVENTH, relating to interested director transactions, is hereby renumbered as Article EIGHTH and amended to read as follows: "EIGHTH: No contract or transaction between the corporation and one or more of its directors or officers, or between the corporation and any other corporation, partnership, association, or other organization in which one or more of its directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board of Directors or committee thereof which authorizes the contract or transaction, or solely because his or their votes are counted for such purpose, if: (1) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board of Directors or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (2) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (3) the contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified, by the Board of Directors, a committee thereof, or the stockholders. Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction." (h) Article TWELFTH, relating to indemnification, is hereby renumbered as Article NINTH and amended to read as follows: "NINTH: The Corporation shall, to the fullest extent possible permitted by Sections 721 through 726 of the Business Corporation Law of New York, indemnify any and all directors and officers whom it shall have the power to indemnify under said sections from and against any and all C-11

of the expenses, liabilities or other matters referred to in or covered by such sections of the Business Corporation Law, and the indemnification provided for herein shall not be deemed exclusive of any other rights to which the person so indemnified may be entitled under any By-Law, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in his/her official capacity and as to action in another capacity by holding such office, and shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such person." (i) Article TENTH, limiting the personal liability of the Corporation's directors to the Corporation and its shareholders, is hereby added to read: "TENTH: A director of the Corporation shall not be personally liable to the Corporation or its shareholders for damages for any breach of duty as a director; provided that, except as hereinafter provided, this Article TENTH shall neither eliminate nor limit liability: (a) if a judgment or final adjudication adverse to the director establishes that (i) the director's acts or omissions were in bad faith or involved intentional misconduct or a knowing violation of law, (ii) the director personally gained in fact a financial profit or other advantage to which the director was not legally entitled, or (iii) the director's acts violated Section 719 of the New York Business Corporation Law; or (b) for any act or omission prior to the effectiveness of this Article TENTH. If the Corporation hereafter may by law be permitted to further eliminate or limit the personal liability of directors, then pursuant hereto the liability of a director of the Corporation shall, at such time, automatically be further eliminated or limited to the fullest extent permitted by law. Any repeal of or modification to the provisions of this Article TENTH shall not adversely affect any right or protection of a director of the Corporation existing pursuant to this Article TENTH immediately prior to such repeal or modification." 4. The text of the Certificate of Incorporation, as amended heretofore, is hereby restated as further amended to read as herein set forth in full: FIRST: The name of the Corporation shall be ACURA PHARMACEUTICALS, INC. SECOND: The purpose of the Corporation is to engage in any lawful act or activity for which Corporations may be organized under the Business Corporation Law of the State of New York; provided, however, that it is not formed to engage in any act or activity requiring the consent or approval of any state official, department, board, agency or any other body without such consent or approval first being obtained. THIRD: The Corporation is authorized to issue two classes of stock, to be designated, respectively, "Common Stock" and "Preferred Stock". The total number of shares which the Corporation is authorized to issue is 940,000,000 of which (A) 290,000,000 shares shall be Preferred Stock (the "Preferred"), and (B) 650,000,000 shares shall be Common Stock, $.01 par value (the "Common"). Of the Preferred, 45,000,000 shares shall be designated Series A Convertible Preferred Stock, $.01 par value per share (the "Series A Preferred"), 25,000,000 shares shall be designated Series B Convertible Preferred Stock, $.01 par value per share (the "Series B Preferred"), 70,000,000 shares shall be designated Series C-1 Convertible Preferred Stock, $.01 par value per share (the "Series C-1 Preferred"), 50,000,000 shares shall be designated Series C-2 Convertible Preferred Stock, $.01 par value per share (the "Series C-2 Preferred") and 100,000,000 shares shall be designated Series C-3 Convertible Preferred Stock, $.01 par value per share (the "Series C-3 Preferred"). The Series C-1 Preferred, Series C-2 Preferred and Series C-3 Preferred are sometimes referred to collectively as the "Series C Preferred". The rights, preferences and privileges of and restrictions on the Series A Preferred, Series B Preferred, Series C Preferred and Common are as follows: SECTION 1. PREFERRED STOCK (a) Voting Rights. Except as otherwise required by law, each share of outstanding Series A Preferred, Series B Preferred and Series C Preferred shall entitle the record holder thereof to vote on C-12

each matter submitted to a vote of the stockholders of the Corporation and to have the number of votes equal to the number of whole shares of Common into which such share of Series A Preferred, Series B Preferred or Series C Preferred, as the case may be, is then convertible pursuant to the provisions hereof at the record date for the determination of stockholders entitled to vote on such matters or, if no such record date is established, at the date such vote is taken or any written consent of stockholders becomes effective. Except as otherwise required by law or by this Certificate, the holders of shares of Common, Series A Preferred, Series B Preferred and Series C Preferred shall vote together and not as separate classes. Fractional votes shall not be permitted and any fractional voting rights resulting from the above formula shall be rounded to the nearest whole number (with one-half rounded upwards). (b) Dividends. If any dividend or other distribution payable in cash, securities or other property is declared on the Common (other than in connection with Section 1(c) below), each holder of shares of Preferred on the record date for such dividend or distribution shall be entitled to receive, on the date of payment or distribution of such dividend or other distribution, the same cash, securities or other property which such holder would have received on such record date if such holder was the holder of record of the number of whole shares of Common into which the shares of Preferred then held by such holder are then convertible (with any resulting fractions rounded to the nearest whole share, with one-half rounded up). (c) Liquidation Rights. If the Corporation shall be voluntarily or involuntarily liquidated, dissolved or wound up (each, a "Liquidation Event"): (1) Prior and in preference to any payments or distributions under Sections 1(c)(2), 1(c)(3) and 1(c)(4) below, the holder of each then outstanding share of Series A Preferred shall be entitled to receive, out of the assets of the Corporation legally available for distribution to stockholders, and before any payment or declaration and setting apart for payment of any amount or dividend pursuant to Sections 1(c)(2) or 1(c)(3) below or with respect to the Common or any other junior equity security of the Corporation, the amount (the "Series A Preference") equal to $3.2125 per share (such amount to be adjusted proportionally in the event the Series A Preferred is subdivided into a greater number or combined into a lesser number of shares). If the Corporation shall have insufficient assets and funds to pay such amounts in full to the holders of the Series A Preferred, then all assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series A Preferred in proportion to the preferential amount each such holder is otherwise entitled to receive pursuant to this Section 1(c)(1). (2) After full payment of the distributions under Section 1(c)(1) above, but prior and in preference to any payments or distributions under Sections 1(c)(3) and 1(c)(4) below, the holder of each then outstanding share of Series B Preferred shall be entitled to receive, out of the assets of the Corporation legally available for distribution to stockholders, and before any payment or declaration and setting apart for payment of any amount or dividend pursuant to Section 1(c)(3) below or with respect to the Common or any other junior equity security of the Corporation, the amount (the "Series B Preference") equal to $.3420 per share (such amount to be adjusted proportionally in the event the Series B Preferred is subdivided into a greater number or combined into a lesser number of shares). If the Corporation shall have insufficient assets and funds to pay such amounts in full to the holders of the Series B Preferred (after payment in full of all amounts pursuant to Section 1(c)(1) above), then all remaining assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series B Preferred in proportion to the preferential amount each such holder is otherwise entitled to receive pursuant to this Section 1(c)(2). (3) After full payment of the distributions under Sections 1(c)(1) and 1(c)(2) above, but prior and in preference to any payments or distributions under Section 1(c)(4) below, the holder of each then outstanding share of Series C Preferred shall be entitled to receive, out of C-13

the assets of the Corporation legally available for distribution to stockholders, and before any payment or declaration and setting apart for payment of any amount or dividend with respect to the Common or any other junior equity security of the Corporation, (i) in the case of Series C-1 Preferred, the amount (the "Series C-1 Preference") equal to $.5776 per share, (ii) in the case of Series C-2 Preferred, the amount (the "Series C-2 Preference") equal to $.5993 per share, and (iii) in the case of Series C-3 Preferred, the amount (the "Series C-3 Preference") equal to $.3481 per share, (in each case such amount to be adjusted proportionally in the event the Series C-1 Preferred, Series C-2 Preferred or Series C-3 Preferred, as applicable, is subdivided into a greater number or combined into a lesser number of shares). If the Corporation shall have insufficient assets and funds to pay such amounts in full to the holders of the Series C Preferred (after payment in full of all amounts pursuant to Sections 1(c)(1) and 1(c)(2) above), then all remaining assets and funds of the Corporation legally available for distribution shall be distributed ratably among the holders of the Series C Preferred in proportion to the preferential amount each such holder is otherwise entitled to receive pursuant to this Section 1(c)(3). (4) After full payment has been made to the holders of Series A Preferred, Series B Preferred and Series C Preferred of the liquidation preferences in Sections 1(c)(1), 1(c)(2) and 1(c)(3), the entire remaining assets and funds, if any, shall be distributed ratably among the holders of Common and the Series A Preferred, in proportion to the number of shares of Common held by them on an as-converted basis; provided, that for purposes of calculating the distribution pursuant to this Section 1(c)(4), and for no other purposes whatsoever, each share of Series A Preferred shall be deemed to be convertible into only 30% of the shares of Common into which it is convertible pursuant to the terms of Section 1(d) below. (5) For purposes of this Section 1(c), unless the holders of a majority of the then outstanding shares of Series A Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be) together as a single class, elect otherwise, (i) the consummation of any merger, consolidation or similar transaction or series of related transactions, the result of which is that the holders of the Corporation's capital stock outstanding immediately prior to such transaction own, immediately upon the consummation of such transaction(s), shares of capital stock possessing in the aggregate less than a majority of the voting power of the surviving entity or rights to liquidation distributions of less than 50% of the assets of the surviving entity, (ii) a sale, lease, exclusive license, transfer or other conveyance of all or substantially all of the assets of the Corporation, or (iii) the sale of 50% or more of the Corporation's voting stock in one or more series of transactions, shall (for purposes of the distribution of such securities or other consideration to the holders of Common and Preferred) be treated as a Liquidation Event and shall entitle the holders of Common and Preferred to receive at closing in cash, securities or other property (valued as provided in Section 1(c)(6) below) as specified above and in the order of preference as set forth in this Section 1(c). (6) Whenever the distribution provided in this Section 1(c) shall be payable in property other than cash, subject to the provisions regarding valuation of securities set forth below, the value of such distribution shall be its fair market value as determined in good faith by the Board of Directors of the Corporation (the "Board"). The holders of a majority of the Series A Preferred will have 10 days from the determination of the valuation of any securities or other property pursuant this Section 1(c) to object to such valuation in writing to the Corporation. In the event of such objection, the Corporation and a majority in interest of the objecting stockholders will in good faith seek a resolution of any disputed valuation. If the Corporation and the objecting investors are unable to agree on a valuation within 5 days of the objection by the holders of the Series A Preferred, the valuation will be determined by an independent third party appraiser jointly selected by the Corporation and the holders of a majority of the then outstanding shares of Series A Preferred, whose written appraised value will be binding on the Corporation and its stockholders. Any distributions pursuant to this Section 1(c) will be C-14

delayed until after the delivery of the appraiser's report. Any securities shall be valued as follows: (i) Securities not subject to investment letter or other similar restrictions on free marketability covered by (ii) below: (A) If traded on a securities exchange or through the Nasdaq National Market or the Nasdaq SmallCap Market, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the 30-day period ending three (3) days prior to the date of determination; (B) If actively traded over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the thirty-day period ending three (3) days prior to the date of determination; and (C) If there is no active public market, the value shall be determined by an independent third party appraiser jointly selected by the Corporation and the holders of a majority of the then outstanding shares of Series A Preferred. (ii) The method of valuation of securities subject to investment letter or other restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder's status as an affiliate or former affiliate) shall be to apply an appropriate discount determined in good faith by the Board from the market value determined as above in (A), (B) or (C). (7) The Corporation shall promptly provide to the holders of shares of Preferred such information concerning the terms of any event or transaction specified in Section 1(c)(5) and the value of the assets of the Corporation as may reasonably be determined by the Board. If the transaction is a sale of all or substantially all of the assets of the Corporation, the Corporation will give written notice of such transaction to each holder of Preferred not less than 20 or more than 60 days before the stockholders' meeting called to approve the transaction or, if no stockholders' meeting will be called, not less than 20 or more than 60 days before the date that the transaction is reasonably anticipated to be consummated, and will also notify the holders in writing of the final approval of the transaction. The initial notice will describe the material terms and conditions of the proposed transaction. The Corporation will give the holders of Preferred prompt notice of any material changes to the terms of the proposed transaction. The Corporation will not consummate the proposed transaction sooner than 20 days after the Corporation has given notice of any material changes. By written consent or vote, the holders of a majority of the shares of Series A Preferred outstanding may shorten the notice periods provided in this Section. In the event the requirements of this Section are not complied with, the Corporation will either: (i) cause the closing to be postponed until the requirements of this Section have been complied with; or (ii) cancel the transaction, in which event the rights, preferences, privileges and restrictions of the holders of the Preferred will revert to the rights, preferences, privileges and restrictions existing immediately before the date of the first notice referred to in this Section. (d) Conversion. (1) Terms of Conversion. (i) Optional Conversion. The holder of each share of Series A Preferred, Series B Preferred and Series C Preferred shall have the right ("Conversion Right"), at such holder's option, to convert such share at any time, without cost, on the terms of this Section 1(d) and at the office of the Corporation or its transfer agent, into the number of fully paid and non-assessable shares of Common that results from dividing (A) in the case of the Series A Preferred, the Series A Preference by the Series A conversion price that is in effect at the time of conversion (the "Series A Conversion Price"), (B) in the case of the Series B Preferred, the C-15

Series B Preference by the Series B conversion price that is in effect at the time of conversion (the "Series B Conversion Price"), (C) in the case of the Series C-1 Preferred, the Series C-1 Preference by the Series C-1 conversion price that is in effect at the time of conversion (the "Series C-1 Conversion Price"), (D) in the case of the Series C-2 Preferred, the Series C-2 Preference by the Series C-2 conversion price that is in effect at the time of conversion (the "Series C-2 Conversion Price") and (E) in the case of the Series C-3 Preferred, the Series C-3 Preference by the Series C-3 conversion price that is in effect at the time of conversion (the "Series C-3 Conversion Price"). The initial Series A Conversion Price is equal to $.6425. The initial Series B Conversion Price is equal to the Series B Preference. The initial Series C-1 Conversion Price is equal to the Series C-1 Preference. The initial Series C-2 Conversion Price is equal to the Series C-2 Preference. The initial Series C-3 Conversion Price is equal to the Series C-3 Preference. The Series A Conversion Price, the Series B Conversion Price, the Series C-1 Conversion Price, the Series C-2 Conversion Price and the Series C-3 Conversion Price shall be subject to adjustment from time to time as provided in Section 1(d)(3) below. (ii) Mandatory Conversion. (A) Upon the occurrence of a Qualified Trading Event, each share of Series A Preferred, Series B Preferred and Series C Preferred shall be automatically converted, without cost and on the terms of this Section 1(d), into the number of whole shares of Common into which such share of Series A Preferred, Series B Preferred or Series C Preferred, as the case me be, would be convertible under Section 1(d)(1)(i) above immediately prior to such Qualified Trading Event (with any resulting fractions rounded to the nearest whole share, with one-half rounded up). "Qualified Trading Event" means the first such time that (A) the Common has a closing price of at least $2.80 per share (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares) for thirty consecutive trading days, and (B) the average daily trading value of all shares of Common traded during such thirty consecutive trading day period is at least $1,750,000. For purposes of this test, (x) closing prices shall be determined as the average between the closing bid and ask prices at the close of each trading day (as reported by such exchange or over-the-counter market on which the Common may then be listed or admitted for trading), and (y) the trading value shall be determined by multiplying the number of shares so traded by such day's closing price as determined above. (B) Without limiting subsection (ii)(A) above, each share of Series A Preferred, Series B Preferred and Series C Preferred shall be automatically converted without cost and on the terms of this Section 1(d), into the number of whole shares of Common into which such share of Series A Preferred, Series B Preferred or Series C Preferred, as the case may be, would be convertible under Section 1(d)(1)(i) above upon the receipt of the written consent of the holders of at least 51% of the shares of Series A Preferred. (2) Mechanics of Conversion. (i) Optional Conversion. A holder of any share of Convertible Preferred may exercise the Conversion Right of such share by surrendering the certificate therefor, duly endorsed, at the office of the Corporation or of any transfer agent for the applicable Preferred, together with a written notice to the Corporation which shall state (A) that such holder elects to convert the same, and (B) the number of shares of Preferred being converted. Thereupon the Corporation shall issue and deliver to the holder of such shares within two (2) business days a certificate or certificates for the number of shares of Common to which such holder shall be entitled. If the certificate evidencing the Preferred being converted shall also evidence shares of Preferred not being converted, then the Corporation shall also deliver to the holder of such certificate within such two (2) business day period a new stock certificate evidencing the Preferred not converted. The conversion of any shares of Preferred shall be deemed to have been made immediately prior to the close of business on the date that the shares to be converted are surrendered to the C-16

Corporation, and the person or persons entitled to receive the shares of Common issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common on such date. Any dividends or distributions declared but unpaid at the time of conversion with respect to the Preferred so converted shall be paid to the holder of Common issued upon conversion of the Preferred. If a stockholder notifies the Corporation or its transfer agent in writing that the stockholder's certificate has been lost, stolen or destroyed, and executes an agreement in a form reasonably satisfactory to the Corporation and its transfer agent to indemnify them from any loss incurred in connection with the lost, stolen or destroyed certificates (without requirement of posting any bond), then such actions shall be treated for purposes of this Section as delivery of such lost, stolen or destroyed certificate. (ii) Mandatory Conversion. The Corporation shall give written notice to each holder of a share of Preferred not more than ten (10) days after the occurrence of a Qualified Trading Event or the receipt of the written consent required pursuant to Section 1(d)(1)(ii)(B), as applicable. Following the conversion of such shares, each holder of shares so converted shall, if requested by the Corporation, surrender the certificate therefor at the office of the Corporation or any transfer agent for the applicable Preferred. Upon such surrender, the Corporation shall issue and deliver to each holder a certificate or certificates for the number of shares of Common to which such holder is entitled. The conversion of shares of Preferred shall be effective as of the occurrence of the Qualified Trading Event or upon receipt of the written consent provided in Section 1(d)(1)(ii)(B), as applicable, whether or not the certificates representing such shares of Preferred shall have been surrendered or new certificates representing the shares of Common into which such shares have been converted shall have been issued. Any dividends or distributions declared but unpaid at the time of a mandatory conversion with respect to the Preferred so converted shall be paid upon such mandatory conversion. If a stockholder notifies the Corporation or its transfer agent in writing that the stockholder's certificate has been lost, stolen or destroyed, and executes an agreement in a form reasonably satisfactory to the Corporation and its transfer agent to indemnify them from any loss incurred in connection with the lost, stolen or destroyed certificates (without requirement of posting any bond), then such actions shall be treated for purposes of this Section as delivery of such lost, stolen or destroyed certificate. (3) Adjustment of Conversion Prices. The Series A Conversion Price, the Series B Conversion Price, the Series C-1 Conversion Price, the Series C-2 Conversion Price and the Series C-3 Conversion Price (each a "Conversion Price") and the kind of securities issuable upon the conversion of any share of Series A Preferred, Series B Preferred, Series C-1 Preferred, Series C-2 Preferred and Series C-3 Preferred (collectively, the "Convertible Preferred"), shall be adjusted from time to time after the Filing Date (as defined below) as follows: (i) Subdivision or Combination of Shares. If the Corporation at any time after the date that this Amended and Restated Certificate of Incorporation was filed with the New York Secretary of State ("Filing Date") effects a subdivision or combination of the outstanding Common, the Conversion Price for each share of outstanding Convertible Preferred shall be decreased, in the case of a subdivision, or increased, in the case of a combination, in the same proportions as the Common is subdivided or combined, in each case effective automatically upon, and simultaneously with, the effectiveness of the subdivision or combination which gives rise to the adjustment. (ii) Stock Dividends. If the Corporation at any time after the Filing Date pays a dividend, or makes any other distribution, to holders of Common payable in shares of Common, or fixes a record date for the determination of holders of Common entitled to receive a dividend or other distribution payable in shares of Common, the Conversion Price for each share of Convertible Preferred shall be decreased by multiplying it by a fraction: C-17

(A) the numerator of which shall be the total number of shares of Common outstanding immediately prior to the time of payment of such dividend or distribution; and (B) the denominator of which shall be the total number of shares of Common outstanding immediately after such dividend or distribution, in each case effective automatically as of the date the Corporation shall take a record of the holders its Common for the purpose of receiving such dividend or distribution (or if no such record is taken, as of the effectiveness of such dividend or distribution). (iii) Reclassification, Consolidation or Merger. If at any time after the Filing Date, as a result of (a) a capital reorganization or reclassification (other than a subdivision, combination or dividend which gives rise to an adjustment of a Conversion Price pursuant to clauses (i) or (ii) of this Section 1(d)(3)); or (b) a merger or consolidation of the Corporation with another corporation (whether or not the Corporation is the surviving corporation), the Common issuable upon the conversion of the Convertible Preferred shall be changed into or exchanged for the same or a different number of shares of any class or classes of stock of the Corporation or any other corporation, or other securities convertible into such shares, then, as a part of such reorganization, reclassification, merger or consolidation, appropriate adjustments shall be made in the terms of the Convertible Preferred (or of any securities into which the Convertible Preferred is changed or for which the Convertible Preferred is exchanged), so that: (x) the holders of Convertible Preferred or of such substitute securities shall thereafter be entitled to receive, upon conversion of the Convertible Preferred or of such substitute securities, the kind and amount of shares of stock, other securities, money and property which such holders would have received at the time of such capital reorganization, reclassification, merger, or consolidation, if such holders had converted their Convertible Preferred immediately prior to such capital reorganization, reclassification, merger, or consolidation, and (y) the Convertible Preferred or such substitute securities shall thereafter be adjusted on terms as nearly equivalent as may be practicable to the adjustments theretofore provided in this Section 1(d)(3). No consolidation or merger in which the Corporation is not the surviving corporation shall be consummated unless the surviving corporation shall agree, in writing, to the provisions of this Section 1(d)(3)(iii). The provisions of this Section 1(d)(3)(iii) shall similarly apply to successive capital reorganizations, reclassifications, mergers, and consolidations. (iv) Adjustment upon Certain Issuances. (A) For purposes of this Section 1(d)(3)(iv), "Additional Shares of Common" means all shares of Common issued by the Corporation after the Filing Date other than: (1) shares of Common issued in transactions giving rise to adjustments under Sections 1(d)(3)(i), (ii), or (iii) above; (2) shares of Common issued upon conversion of shares of Convertible Preferred; (3) shares of Common which may be issued in the discretion of the Board to employees or directors of, or consultants or advisors to, strategic partners of the Corporation or any wholly-owned subsidiary of the Corporation, and options or warrants or other rights for the purchase of such shares; (4) options or warrants or other rights outstanding as of the Filing Date or issued under Section 1(d)(3)(iv)(3) above for the purchase of such shares; (5) securities issued pursuant to any anti-dilution rights of the Convertible Preferred or the warrants outstanding as of the Filing Date; and (6) shares of Common Stock issued in satisfaction of interest on the Corporation's indebtedness for borrowed money, provided the number of shares of Common Stock issuable is calculated based on the average closing bid and asked prices for the Common Stock for the twenty (20) trading days preceding the interest payment. (B) Except as otherwise provided in this Section 1(d)(3)(iv) below, if at any time the Corporation issues or is deemed to issue Additional Shares of Common for a C-18

consideration per share less than the Conversion Price in effect for a given share at such issuance or deemed issuance: (1) in the case of the Series A Preferred, the Conversion Price shall be reduced for such share to a price equal to a price determined by dividing: (x) the aggregate consideration received by or deemed to have been received by the Corporation upon such issue, by: (y) the number of shares of Additional Shares of Common issued or deemed to have been issued in such issue; and (2) in the case of the Series B Preferred, Series C-1 Preferred, Series C-2 Preferred or Series C-3 Preferred, the Conversion Price shall be reduced for such share to a price equal to a price determined by dividing: (x) the sum of (a) the product derived by multiplying the Conversion Price in effect for such share immediately prior to such issue times the number of shares of Common (on a fully-diluted basis) outstanding immediately prior to such issue, plus (b) the aggregate consideration received by or deemed to have been received by the Corporation upon such issue; by (y) the sum of (a) the number of shares of Common (on a fully-diluted basis) outstanding immediately prior to such issue, plus (b) the number of shares of Additional Shares of Common issued or deemed to have been issued in such issue; provided, that no adjustment pursuant to this Section 1(d)(3)(iv)(B)(2) shall be made in connection with any issuance or deemed issuance of Additional Shares of Common for a consideration of at least the then applicable Series A Conversion Price. (v) Convertible Securities. (A) "Convertible Securities" means all rights or options for the purchase of, or stock or other securities convertible into, Additional Shares of Common or other Convertible Securities, whenever and each time issued. (B) The "Effective Price" with respect to any Convertible Securities means the result of dividing: (1) the sum of (x) the total consideration, if any, received by the Corporation for the issuance of such Convertible Securities, plus (y) the minimum consideration, if any, payable to the Corporation upon exercise or conversion of such Convertible Securities (assuming that the full amount of securities issuable upon exercise or conversion are issued), plus (z) the minimum consideration, if any, payable to the Corporation upon exercise or conversion of any Convertible Securities issuable upon exercise or conversion of such Convertible Securities, by: (2) the maximum number of Additional Shares of Common issuable upon exercise or conversion of such Convertible Securities or of any Convertible Securities issuable upon exercise or conversion of such Convertible Securities. (C) If at any time after the Filing Date the Corporation issues or is deemed to issue a Convertible Security with respect to which the Effective Price is less than the Conversion Price for a share of Convertible Preferred in effect at such issuance or deemed issuance, the Conversion Price for such share of Convertible Preferred shall be reduced to the Effective Price. (D) If Convertible Securities by their terms provide, with the passage of time or otherwise (including by operation of the anti-dilution provisions thereof), for any increase or decrease in the consideration payable to the Corporation or decrease or increase in the number of shares of Common issuable upon the exercise, conversion or exchange thereof C-19

(or if any such change is made by amending such Convertible Securities), the Conversion Price computed upon the original issue thereof, and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such the rights of conversion or exchange under such Convertible Securities. No readjustment pursuant to this clause (D) shall have the effect of increasing the applicable Conversion Price in effect to an amount which exceeds the lower of (1) the Conversion Price immediately following, and as adjusted to reflect, the Company's issuance of such Convertible Securities (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization affecting such shares), or (2) the Conversion Price that would have resulted from any issuances of Additional Shares of Common or Convertible Securities between the date the Company adjusted the Conversion Price to reflect the issuance of such original Convertible Securities and such readjustment date. (E) If an adjustment has been made under this Section 1(d)(3)(v) as a consequence of any issuance of a Convertible Security, then no further adjustment shall be made under Section 1(d)(3)(iv) above upon the actual issuance of Additional Shares of Common upon the exercise or conversion of such Convertible Securities, or upon the issuance of Convertible Securities issuable upon exercise or conversion of the original Convertible Security. (vi) Valuation of Consideration. For purposes of the operation of Sections 1(d)(3)(iv) and (v) above, the consideration received by the Corporation for any issue or sale of securities shall: (A) to the extent it consists of cash, be computed as the aggregate net amount of cash received by the Corporation; (B) to the extent it consists of property other than cash, be computed at the fair value of that property as determined in good faith by the Board in accordance with the terms of Section 1(c)(6) above; and (C) to the extent Additional Shares of Common or Convertible Securities are issued or sold together with other stock or securities or other assets of the Corporation for a consideration that covers both, be such portion of the consideration so received that may be reasonably determined in good faith by the Board to be allocable to such Additional Shares of Common or Convertible Securities. (vii) Other Action Affecting Common. If at any time the Corporation takes any action affecting its Common which, in the opinion of the Board, would have an adverse effect upon the Conversion Rights of a given share of the Convertible Preferred, the Conversion Price for such share and the kind of securities issuable upon the conversion of such share shall be adjusted in such manner and at such time as the Board may in good faith determine to be equitable in the circumstances. (vii) Notice of Adjustments. Whenever the Conversion Price or the kind of securities issuable upon the conversion of any one of or all of the Convertible Preferred shall be adjusted pursuant to Section 1(d)(3)(i)-(v) or (vii) above, the Corporation shall make a certificate signed by its Chief Financial Officer, Secretary or Assistant Secretary, setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis on which the Board made any determination hereunder), and the Conversion Price and the kind of securities issuable upon the conversion of such share(s) of the Convertible Preferred after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail postage prepaid) to each holder of Convertible Preferred promptly after each adjustment. C-20

(4) Full Consideration. All shares of Common which shall be issued upon the conversion of any Convertible Preferred (which is itself fully paid and non-assessable) will, upon issuance, be fully paid and non-assessable. The Corporation will pay such amounts and will take such other action as may be necessary from time to time so that all shares of Common which shall be issued upon the conversion of any Convertible Preferred will, upon issuance and without cost to the recipient, be free from all pre-emptive rights, taxes, liens and charges with respect to the issue thereof. (5) No Impairment. The Corporation will not, by amendment of its Amended and Restated Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section 1(d) and in the taking of all such action as may be necessary or appropriate in order to protect the Conversion Rights of any holder of the Convertible Preferred against impairment. The Corporation shall at all times when the Convertible Preferred shall be outstanding, reserve and keep available out of its authorized but unissued stock, for the purpose of effecting the conversion of the Convertible Preferred, such number of its duly authorized shares of Common as shall from time to time be sufficient to effect the conversion of all outstanding shares of Convertible Preferred. (6) No Reissuance of Preferred. No share of Preferred acquired by the Corporation upon conversion, redemption or purchase shall be reissued and all such shares shall be canceled, retired and eliminated from the shares which the Corporation may be authorized to issue. The Corporation shall take all such corporate action necessary or appropriate to reduce the authorized number of Preferred accordingly. (7) Minimum Conversion Price. Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value of the shares of Common issuable upon conversion of the shares of Convertible Preferred, the Corporation will take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and nonassessable shares of Common at such adjusted Conversion Price. SECTION 2. COMMON STOCK (a) Voting Rights. Except as otherwise required by law or by this Certificate, each share of Common shall entitle the holder thereof to one vote on each matter submitted to a vote of the stockholders of the Corporation, and the holders of shares of Common, Series A Preferred, Series B Preferred and Series C Preferred shall vote together and not as separate classes. (b) Dividend Rights. Subject to the dividend rights of the holders of the Preferred set forth in Sections 1(b) and 1(c) above, the holders of the Common shall be entitled to receive, as, when and if declared by the Board, but only out of funds legally available therefor, cash dividends in such amounts as the Board may determine. (c) Liquidation Rights. In the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, after payment or provision for payment of the debts and other liabilities of the Corporation and the preferential amounts to which the holders of any outstanding shares of Preferred shall be entitled to receive upon dissolution, liquidation, or winding up, the holders of the Common shall be entitled to share on a share for share basis in the remaining assets of the Corporation (together with the holders of Series A Preferred as set forth in Section 1(c)(4) above). (d) Residual Rights. All rights accruing to the outstanding shares of the Corporation not otherwise expressly provided for herein shall be vested in the Common. C-21

EIGHTH: No contract or transaction between the corporation and one or more of its directors or officers, or between the corporation and any other corporation, partnership, association, or other organization in which one or more of its directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board of Directors or committee thereof which authorizes the contract or transaction, or solely because his or their votes are counted for such purpose, if: (1) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board of Directors or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (2) the material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (3) the contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified, by the Board of Directors, a committee thereof, or the stockholders.

adjudication adverse to the director establishes that (i) the director's acts or omissions were in bad faith or involved intentional misconduct or a knowing violation of law, (ii) the director personally gained in fact a financial profit or other advantage to which the director was not legally entitled, or (iii) the director's acts violated Section 719 of the New York Business Corporation Law; or (b) for any act or omission prior to the effectiveness of this Article TENTH. If the Corporation hereafter may by law be permitted to further eliminate or limit the personal liability of directors, then pursuant hereto the liability of a director of the Corporation shall, at such time, automatically be further eliminated or limited to the fullest extent permitted by law.

APPENDIX D AGEMA LLC January 16, 2004 STRICTLY PRIVATE AND CONFIDENTIAL Independent Committee of the Board of Directors Halsey Drug Co., Inc. 695 North Perryville Road Rockford, Illinois 61107 Gentlemen: We understand that Halsey Drug Co., Inc. ("Halsey" or the "Company") has sought the advice of an Independent Committee of Halsey's Board of Directors (the "Committee") with regard to financial transactions by Halsey pursuant to terms and conditions more fully described in drafts of the transaction documents and related agreements listed in Exhibit A of this letter (the "Transaction Documents"). The financial transactions embodied in the Transaction Documents collectively constitute the "Financing". Amongst other terms and Conditions, the Financing provides for: 1. the sale of convertible senior secured debentures (the "Debentures") of $11.3 million principal amount to Essex Woodlands Health Ventures V, L.P., Care Capital Investments, LP, Galen Partners III, L.P. and Oracle Strategic Partners L.P. (collectively, including affiliated entities, the "Investors"), and 2. the exchange of (i) approximately $2.0 million of aggregate funding which has occurred since November 21, 2003, and (ii) any funding provided by the Investors during the period from January 16, 2004 to the initial closing (collectively, the "Bridge Notes"), together with accrued interest thereon, for Debentures on the initial closing; and 3. the sale of up to $1.7 million in Debentures within 120 days of the initial closing in addition to the Debentures to be acquired by the Investors; and 4. the utilization of $4.0 million of the proceeds raised to retire $16.4 million of indebtedness owing by the Company to Watson Pharmaceuticals, Inc. in the aggregate principal amount of approximately $21.4 million. Persons and entities that have preemptive rights and other third parties will also be permitted to purchase Debentures ("Other Purchasers"), so long as the Investors are able to make their desired purchases. You have asked us for our opinion as to whether the Financing is fair from a financial point of view to the Company as well as fair from a financial point of view to the Company's creditors, debenture holders, subordinated debt holders and common shareholders not including the Investors and the Other Purchasers (the "Stakeholders"). For purposes of the opinion set forth herein, we have: (i) reviewed certain publicly available financial statements and other information of the Company; (ii) reviewed internal financial statements and other financial and operating data concerning the Company prepared by the management of the Company; (iii) reviewed, financial projections regarding the Company prepared by the management of the Company; (iv) conducted detailed meetings and telephonic discussions with members of the senior management of the Company concerning the financial condition, current operating results and business outlook for the Company on a stand-alone basis; (v) reviewed the reported prices and trading activity of the Company's common stock; D-1

(vi) discussed with management the Company's efforts during 2003 to identify and negotiate alternative sources of funding on an acceptable basis other than on the terms proposed by the Investors and Other Purchasers; (vii) reviewed the Company's current cash position and cash operating requirements through fiscal year 2004; (viii) participated in discussions among the Company's senior executives, the Committee and legal representatives regarding the status of negotiations with the Investors and Other Purchases and provided financial advice to the Committee; (ix) discussed with the Committee and with management the prospects for the Company if the Financing is not completed; (x) reviewed with the Committee the financial implications of various term sheets submitted by the Investors and Other Purchasers to the Company and provided financial advice to the Committee in response thereto; (xi) discussed the tax implications of the consummation of the Financing with the Committee and their counsel; (xii) reviewed the Transaction Documents; and (xiii) performed such other analyses and considered such other factors as we have deemed appropriate. The payment of our fee for this opinion is not contingent upon the consummation of the Financing. The Company has also agreed to indemnify us against certain liabilities in connection with our services. We have assumed and relied upon, without independent verification, the accuracy and completeness of the information reviewed by us for the purposes of this opinion. With respect to the financial projections, we have assumed that they have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the future financial performance of the Company. We have not made and do not assume any responsibility for making any independent valuation or appraisal of the assets or liabilities of the Company, nor have we been furnished with any such appraisals. We express no opinion as to the relative financial impact of the Financing upon the Stakeholders of the Company, including without limitation, no opinion as to the recoverability of financial investments or credit extended by any of the Stakeholders of the Company. We have assumed that the Financing will be consummated in accordance with the terms and conditions set forth in the Transaction Documents without material modification or waiver. Our opinion is necessarily based on financial, economic market and other conditions as in effect on, and the information made available to us as of, the date hereof, but our opinion does not address the Company's underlying business decision to effect the transactions contemplated by the Transaction Documents. We have acted as financial advisor to the Committee of the Board of Directors of the Company and have received fees from the Company for our services. It is understood that this letter is for the information of the Committee of the Board of Directors of the Company and may not be used for any other purpose without our prior written consent, except that this opinion may be included in its entirety in any filing made by the Company in respect of the Financing with the Securities and Exchange Commission subject to our prior review. We make no recommendation as to how the common shareholders of the Company should vote with respect to the Financing. D-2

Based on the foregoing, we are of the opinion on the date hereof that the Financing is fair from a financial point of view to the Company and its Stakeholders. Very truly yours, AGEMA LLC By: /s/ JAMES W. NEAL, JR. ------------------------------------ James W. Neal, Jr. Chairman and Chief Executive Officer D-3

APPENDIX E HALSEY DRUG CO., INC. RESOLUTIONS OF THE INDEPENDENT COMMITTEE OF THE BOARD OF DIRECTORS DECEMBER 20, 2003 WHEREAS, the Board of Directors of Halsey Drug Co., Inc. (the "Company") on October 30, 2003 formed an independent committee of the Board (the "Committee") for the purpose of evaluating the capital raising activities of the Company with the intent of seeing that those efforts are reasonable and unbiased and that all alternatives are considered in the process; WHEREAS, the Committee has undertaken and completed a thorough and detailed evaluation of the Company's capital raising activities including without limitation, but with particular attention to, the proposed terms and conditions of the financing set forth in the Company's December 19, 2003 term sheet attached hereto (the "Term Sheet") to be fully embodied in transaction documents in connection with a convertible senior secured debentures financing with Essex Woodlands Health Ventures Fund V, L.P. ("Essex Woodlands"), Care Capital Investments, L.P. ("Care Capital"), Galen Partners III, L.P. and other Galen entities ("Galen"), Oracle Strategic Partners, L.P. ("Oracle"), and other purchasers (the "2003 Financing"); WHEREAS, the Committee has met formally on numerous occasions and, in addition to those meetings, Committee members have had numerous detailed communications with each other and with the Company's Chief Executive Officer and Chief Financial Officer and other members of management and with the Committee's special legal counsel and financial advisory firm, and the Committee has also been updated from time to time by the Company's outside general counsel as to the progress and status of the 2003 Financing; WHEREAS, during the course of these meetings and communications the Committee has assembled and thoroughly examined, analyzed and evaluated a substantial body of information and materials which the Committee Chairman has instructed the Company's Chief Financial Officer and the Committee's special counsel to retain and preserve in their respective files; WHEREAS, the Committee's evaluations have taken into account the following factors, among other things: the Company's current distressed financial condition and urgent need to obtain new capital and to restructure its existing debt; the fact that the Company is in default of its principal loan agreements; discussions with the Company's management and outside professionals including advice (a) from the Company's bankruptcy counsel as to bankruptcy alternatives which appear to be inevitable in the absence of consummating the 2003 Financing and (b) that the Company's independent certified public accountants expect that in the absence of the 2003 Financing that the Company's 2003 financial statements will almost certainly at a minimum have a going-concern qualification; the substantial effort and numerous attempts made by the Company to obtain necessary financing during 2003 from other sources on acceptable terms but without success other than the proposed 2003 Financing, including the Committee's review of the financing terms that were offered to the Company but found by the Company to be unacceptable; the market price and volume for the Company's publicly traded common stock during the 90-day period through and including December 19, 2003; the dilutive effects on existing stockholders resulting from the 2003 Financing; the Company's financial information, including financial forecasts, and information relating to the Company's business, earnings, cash flow, assets, liabilities, recent aged accounts payable statements, current defaults on existing indebtedness, and prospects of the Company; discussions with members of senior management of the Company concerning the Company's history, current operations and financial status, and future prospects, as well as the outlook for the Company's industry generally and the Company's 2004 business plan and current efforts to liquidate certain assets and reduce payroll; review of documentation and analyses regarding the Company's existing debt financing and liquidity issues; the restricted nature of the securities being issued to the investors pursuant to the 2003 Financing including the restricted nature of the securities issueable upon conversion of the new securities; the Bulletin Board status of the Company and its impact on the liquidity of the Company's securities; the insolvent condition of the Company in both the sense that the Company's liabilities greatly E-1

exceed the Company's assets and the fact that the Company has not been able to satisfy its obligations as they mature; the advice from Agema, LLC (the Committee's financial advisory firm) received at the Committee's December 20, 2003 meeting that the transaction described in the Term Sheet is fair to the Company and its creditors and stockholders from a financial point of view which advice will be confirmed by Agema in a customary fairness opinion letter to be delivered promptly and prior to the closing; and review and evaluation of such other financial information and analyses and such other information and matters as the Committee considered appropriate including the Committee's assessment of general economic, market, and monetary conditions; WHEREAS, the Committee has reviewed the terms and conditions of the 2003 Financing as stated in the Term Sheet and will rely on management and the Company's outside general counsel to assure that the definitive legal documents are consistent with and reflect the terms and conditions outlined in the Term Sheet subject to negotiated changes to the transaction's terms after the Term Sheet which management or the Company's general counsel determines are not material to the Committee's financial evaluation of the transaction; WHEREAS, the Committee's members have actively participated in the negotiation of the Term Sheet, and the material comments and concerns raised by the Committee members have been addressed to their satisfaction in the Term Sheet, taking into account the Company's bargaining position and all the other relevant facts and circumstances of the Company's present situation and financial condition and the customary gives-and-takes during the negotiating process in a transaction of this kind. The Committee has assumed and relied on the accuracy and completeness of all information supplied or otherwise made available to it, assumed that the Company's financial forecasts and forward-looking materials have been reasonably prepared and reflect the best currently available estimates and judgment of management as to the expected future financial performance of the Company, and assumed that any differences between the final executed closing documents and the Term Sheet would not change the Committee's conclusions and recommendation. NOW, THEREFORE, be it hereby RESOLVED, that the Committee hereby concludes, with reliance on the financial fairness opinion of Agema LLC and the other factors recited above, that the 2003 Financing presents the best and, in all likelihood as assessed by the Committee, the only source of capital to satisfy the Company's short-term and long-term needs; that the 2003 Financing is fair from a financial point of view to the creditors and public stockholders of the Company other than Essex, Care Capital, Oracle, and Galen; and that the capital raising activities of the Company have been reasonable and unbiased and that all reasonable alternatives were considered in the process; and, accordingly, the Committee hereby recommends to the Board that the Board approve and authorize the 2003 Financing (with abstentions by appropriate Board members) and proceed to a prompt closing of the transaction.

The Plan described herein, as amended and restated, shall be known as the "Halsey Drug Co., Inc. 1998 Stock Option Plan" (the "Plan"). The purposes of the Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to Employees, Directors and Consultants of the Company or its Subsidiaries (as defined in Section 2 below) to whom Option's may be granted under this Plan, and to promote the success of the Company's business.

The Plan is not intended as an agreement or promise of employment. Neither the Plan, nor any Option granted pursuant to the Plan, shall confer on any person any right to continue in the employ of the Company. The right of the Company to terminate an Employee is not limited by the Plan, nor by any Option granted pursuant to the Plan, unless such right is specifically described by the terms of any such Option. 2.

(h) "Employee" shall mean any person, including officers, employed by the Company or any Parent or Subsidiary of the Company. The payment of a Director's fee by the Company shall not be sufficient to constitute "employment" by the Company. (i) "Exchange Act" shall mean the Securities Exchange Act of 1934, as amended. (j) "Fair Market Value" shall mean (i) the closing price for a share of the Common Stock on the exchange or quotation system which reports or quotes the closing prices for a share of the Common Stock, as accurately reported for any date (or, if no shares of Common Stock are traded on such date, for the immediately preceding date on which shares of Common Stock were traded) in The Wall Street Journal (or if The Wall Street Journal no longer reports such price, in a newspaper or trade journal selected by the Committee) or (ii) if no such price quotation is available, the price which the Committee acting in good faith determines through any reasonable valuation method that a share of Common Stock might change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or to sell and both having reasonable knowledge of the relevant facts. (k) "Incentive Stock Option" shall mean an Option intended to qualify as an incentive stock option within the meaning of Section 422 of the Code. (l) "Non-ISO" shall mean an Option to purchase stock which is not intended by the Committee to satisfy the requirements of Section 422 of the Code.

Stock Authorized. Subject to the provisions of Section 11 of the Plan, the maximum aggregate number of shares which may be Optioned and sold under the Plan is Twenty Million (20,000,000) shares of authorized, but unissued, or reacquired Common Stock. The maximum number of shares which may be subject to an Option granted in any calendar year shall not exceed 8,750,000 shares (subject to adjustment under Section 11 hereof consistent with Section 162(m) of the Code). If the shares that would be issued or transferred pursuant to any Options are not issued or transferred and ceased to be issuable or transferable for any reason, the number of shares subject to such Option will no longer be charged against a limitation provided for herein and may again be subject to Options. Notwithstanding the proceeding sentence, with respect to any Option granted to any individual who is a "covered employee" within the meaning of Section 162(m) of the Code that is cancelled, the number of shares subject to such Option shall continue to count against the maximum number of shares which may be the subject of Options granted to such individual. For purposes of the preceding sentence if, F-2

after grant, the exercise price of an Option is reduced, such reduction shall be treated as a cancellation of such Option and the grant of a new Option, and both the cancellation of the Option and the new Option shall reduce the maximum number of shares for which Options may be granted to the holder of such Option in a calendar year. If an Option should expire or become unexercisable for any reason without having been exercised in full, the unpurchased Shares which were subject thereto shall, unless the Plan shall have been terminated, become available for further grant under the Plan. 4. Administration. (a) Procedure. The Company's Board of Directors may appoint a Committee to administer the Plan which shall be constituted so as to permit the Plan to continue to comply with Rule 16b-3, as currently in effect or as hereafter modified or amended. The Committee appointed by the Board of Directors shall consist of not less than two members of the Board of Directors, to administer the Plan on behalf of the Board of Directors, subject to such terms and conditions as the Board of Directors may prescribe. Once appointed, the Committee shall continue to serve until otherwise directed by the Board of Directors. From time to time, the Board of Directors may increase the size of the Committee and appoint additional members thereof, remove members (with or without cause), and appoint new members in substitution therefor, fill vacancies however caused, or remove all members of the Committee and thereafter directly administer the Plan; provided, however, that at no time shall a Committee of less than two members administer the Plan. Subject to the provisions of the Plan, the Committee shall be authorized to interpret the Plan, to establish, amend and rescind any rules and regulations relating to the Plan and to make all other determinations necessary or advisable for the administration of the Plan. Notwithstanding anything to the contrary contained herein, no member of the Committee shall serve as such under this Plan unless such person is a "Non-Employee Director" within the meaning of Rule 16b-3(b)(3)(i) of the Exchange Act. A majority vote of the members of the Committee shall be required for all of its actions. A majority of the entire Committee shall constitute a quorum, and the action of the majority of the Committee members present at any meeting at which a quorum is present shall be the action of the Committee. All decisions, determinations, and interpretations of the Committee shall be final and conclusive on all persons affected thereby and shall, as to Incentive Stock Options, be consistent with Section 422 of the Code. The Committee shall have all of the powers and duties set forth herein, as well as such additional powers and duties as the Board of Directors may delegate to it; provided, however, that the Board of Directors expressly retains the right in its sole discretion (i) to elect and to replace the members of the Committee, and (ii) to terminate or amend this Plan in any manner consistent with applicable law. (b) Powers of the Committee. Subject to the provisions of the Plan, the Committee shall have the authority, in its discretion: (i) to grant Incentive Stock Options, in accordance with Section 422 of the Code, or to grant Non-ISO's; (ii) to determine the Fair Market Value of the Common Stock; (iii) to determine the exercise price per share of Options to be granted which exercise price shall be determined in accordance with Section 8 of the Plan; (iv) to determine the persons to whom (including, without limitation, members of the Committee) and the time or times at which, Options shall be granted and the number of Shares to be represented by each Option; (v) to interpret the Plan; (vi) to prescribe, amend and rescind rules and regulations relating to the Plan; (vii) to determine the terms and provisions of each Option granted (which need not be identical) and, with the consent of the holder thereof, modify or amend each Option; (viii) to accelerate or defer (with the consent of the Optionee) the exercise date of any Option; (ix) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted by the Board; and (x) to make all other determinations deemed necessary or advisable for the administration of the Plan. F-3

(c) Subject to the provisions of this Plan and compliance with Rule 16b-3 of the Exchange Act, the Committee may grant options under this Plan to members of the Company's Board of Directors, including members of the Committee, and in such regard may determine: (i) the time at which any such Option shall be granted; (ii) the number of Shares covered by any such Option; (iii) the time or times at which, or the period during which, any such Option may be exercised or whether it may be exercised in whole or in installments; (iv) the provisions of the agreement relating to any such Option; and (v) the Option Price of Shares subject to an Option granted such Board member. (d) Effect of the Committee's Decision. All decisions, determinations and interpretations of the Committee shall be final and binding on all Optionees and any other holders of any Options granted under the Plan. 5. Eligibility. Incentive Stock Options may be granted only to Employees. Non-ISO's may be granted to Employees as well as non-employee Directors and Consultants of the Company as determined by the Board or any Committee. Any person who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options. Each grant of an Option shall be evidenced by an Option Agreement, and each Option Agreement shall (1) specify whether the Option is an Incentive Stock Option or a Non-ISO and (2) incorporate such other terms and conditions as the Committee acting in its absolute discretion deems consistent with the terms of this Plan, including, without limitation, a restriction on the number of shares of stock subject to the Option which first become exercisable during any calendar year. To the extent that the aggregate Fair Market Value of the stock of the Company subject to Incentive Stock Options granted (determined as of the date such an Incentive Stock Option is granted) which first become exercisable in any calendar year exceeds $100,000, such Options shall be treated as Non-ISO's. This $100,000 limitation shall be administered in accordance with the rules under Section 422(d) of the Code. 6. Effective Date and Term of Plan. The effective date of this Plan ("Effective Date") shall be the date it is adopted by the Board, provided the shareholders of the Company (acting at a duly called meeting of such shareholders or by the written consent of shareholders) approve this Plan within twelve (12) months after such Effective Date. The effectiveness of Options granted under this Plan prior to the date such shareholder approval is obtained shall be contingent on such shareholder approval. Subject to the provisions of Section 13 hereof, no Option shall be granted under this Plan on or after the earlier of (1) the tenth anniversary of the Effective Date of this Plan in which event the Plan otherwise thereafter shall continue in effect until all outstanding Options shall have been surrendered or exercised in full or no longer are exercisable, or (2) the date on which all of the Common Stock reserved for issuance under Section 3 of this Plan has (as a result of the exercise or expiration of Options granted under this Plan) been issued or no longer is available for use under this Plan, in which event the Plan also shall terminate on such date. 7. Term of Option. An Option shall expire on the date specified in such Option, which date shall not be later than the tenth anniversary of the date on which the Option was granted, except that, if any Employee, at any time an Incentive Stock Option is granted to him or her, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of Common Stock (or, under Section 424(d) of the Code is deemed to own stock representing more than ten percent (10%) of the total combined voting power of all such classes of Common Stock, by reason of the ownership of such classes of stock, directly or indirectly, by or for any brother, sister, spouse, ancestor or lineal descendant of such Employee, or by or for any corporation, partnership, state or trust of which such Employee is a shareholder, partner or beneficiary), the F-4

Incentive Stock Option granted him or her shall not be exercisable after the expiration of five years from the date of grant or such earlier expiration as provided in the particular Option agreement. 8. Exercise Price and Consideration. (a) The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Board, but shall be subject to the following: (i) In the case of an Incentive Stock Option (A) granted to an Employee who, immediately before the grant of such Incentive Stock Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. (B) granted to any Employee, the per share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. (ii) In the case of a Non-ISO, the per Share exercise price shall be determined by the Board on the date of grant. (b) The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Board and may consist entirely of (i) cash; (ii) check; (iii) promissory note, provided such promissory note shall be full recourse as to principal and interest and shall bear interest at the market rate, which market rate shall be equal to the rate of interest available to the Optionee in a third party arms-length loan transaction of similar nature and amount; (iv) Shares of Common Stock having been held by the Optionee for at least six (6) months prior to being surrendered as consideration for the Shares to be issued upon exercise of an Option and having a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, or any combination of such methods of payment; or (v) such other consideration and method of payment for the issuance of Shares to the extent permitted under New York law. The Company shall be permitted to withhold shares to be issued under the Option to pay related income tax withholding requirements. The amount of such tax withholding shall be no greater than the applicable statutory withholding amount. 9. Exercise of Option. (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Committee, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan. An Option may not be exercised for a fraction of a Share. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Board, consist of any consideration and method of payment allowable under Section 8(b) of the Plan. Until the issuance, which in no event will be delayed more than thirty (30) days from the date of the exercise of the Option, (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or F-5

other right for which the record date is prior to the date the stock certificate is issued, except as provided in the Plan. Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. (b) Termination of Status as an Employee, or Director or Consultant with Respect to Non-ISO's. Non-ISO's granted pursuant to the Plan may be exercised notwithstanding the termination of the Optionee's status as an employee, a non-employee Director or a Consultant, except as provided in the Plan or as provided by the terms of the Stock Option Agreement. (c) Termination of Service as an Employee with Respect to Incentive Stock Options. If the Continuous Service of any Employee terminates, he or she may, but only within thirty (30) days (or such other period of time not exceeding three (3) months as is determined by the Committee) after the date he or she ceases to be an Employee of the Company, exercise his or her Option to the extent that he or she was entitled to exercise it as of the date of such termination. To the extent that he or she was not entitled to exercise the Option at the date of such termination, or if he or she does not exercise such Option (which he or she was entitled to exercise) within the time specified herein, the Option shall terminate. (d) Disability of Optionee. Notwithstanding the provisions of Section 9(c) above, in the event an Employee is unable to continue his or her Continued Service with the Company as a result of his or her total and permanent disability (within the meaning of Section 22(e)(3) of the Code), he or she may, but only within three (3) months (or such other period of time not exceeding twelve (12) months as is determined by the Committee) from the date of disability, exercise his or her Option to the extent he or she was entitled to exercise it at the date of such disability. To the extent that he or she was not entitled to exercise the Option at the date of disability, or if he or she does not exercise such Option (which he or she was entitled to exercise) within the time specified herein, the Option shall terminate. (e) Death of Optionee. In the event of the death of an Optionee: (i) during the term of the Option who is at the time of his or her death an Employee of the Company and who shall have been in Continuous Status as an Employee, a Director or Consultant since the date of grant of the Option, the Option may be exercised, at any time within twelve (12) months following the date of death, by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that would have accrued had the Optionee continued living one (1) month after the date of death; or (ii) within thirty (30) days (or such other period of time not exceeding three (3) months as is determined by the Committee) after the termination of Continuous Status as an Employee, a Director or Consultant, the Option may be exercised, at any time within three (3) months following the date of death, by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of termination. 10. Transferability of Options. (a) Incentive Stock Options may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the life time of the Optionee only by the Optionee. (b) The Committee may, in its discretion, authorize all or a portion of the Non-ISOs to be granted to an Optionee to be on terms which permit transfer by such Optionee to (i) the spouse, children or grandchildren of the Optionee (the "Immediate Family Members"), (ii) a trust or trusts for the exclusive benefit of such Immediate Family Members, or (iii) a partnership in which such Immediate Family Members are the only partners, provided that (x) there may be no consideration for any such transfer, (y) the Non-ISO Stock Option Agreement pursuant to which such options are granted must be approved by the Committee, and must expressly provide for transferability in a manner consistent with this section, (z) subsequent transfers of transferred Options shall be prohibited except those made by will or by the laws of descent or distribution, and F-6

(zz) such transfer is approved in advance by the Committee. Following transfer, any such Options shall continue to be subject to the same terms and conditions as were applicable immediately prior to transfer, provided that for purposes of determining the rights of exercise under the Option, the term "Optionee" shall be deemed to refer to the transferee. The termination of service as an employee, non-employee director or consultant shall continue to be applied with respect to the original Optionee, following which the options shall be exercisable by the transferee only to the extent, and for the periods specified in Section 9 of the Plan and in the Stock Option Agreement. 11. Adjustments Upon Changes in Capitalization or Merger. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per share of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split or the payment of a stock dividend with respect to the Common Stock or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or exercise price of shares of Common Stock subject to an Option. In the event of the proposed dissolution or liquidation of the Company, or in the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, the Board may, in the exercise of its sole discretion in such instances, accelerate the vesting of all or any portion of Options then outstanding. 12. Time for Granting Options. The date of grant of an Option shall, for all purposes, be the date on which the Board makes the determination granting such Option. Notice of the determination shall be given to each Employee, non-employee Director and Consultant to whom an Option is so granted within a reasonable time after the date of such grant. 13. Amendment and Termination of the Plan. (a) The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable; provided that, the following revisions or amendments shall require approval of the holders of a majority of the outstanding shares of the Company entitled to vote: (i) any increase in the number of Shares subject to the Plan, other than in connection with an adjustment under Section 11 of the Plan; (ii) any change in the class of Employees which are eligible participants for Options under the Plan; or (iii) if shareholder approval of such amendment is required for continued compliance with Rule 16b-3. (b) Shareholder Approval. Any amendment requiring shareholder approval under Section 13(a) of the Plan shall be solicited as described in Section 17 of the Plan. (c) Effect of Amendment or Termination. Any such amendment or termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee and the Company. 14. Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as F-7

amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law. 15. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 16. Option Agreement. Options shall be evidenced by written Option agreements in such form as the Committee shall approve. 17. Shareholder Approval. Continuance of the Plan shall be subject to approval by the shareholders of the Company within twelve months before or after the date the Plan is adopted. If such shareholder approval is obtained at a duly held shareholders' meeting, it may be obtained by the affirmative vote of the holders of a majority of the outstanding shares of the Company present or represented and entitled to vote thereon. The approval of such shareholders of the Company shall be (1) solicited substantially in accordance with Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder, or (2) solicited after the Company has furnished in writing to the holders entitled to vote substantially the same information concerning the Plan as that which would be required by the rules and regulations in effect under Section 14(a) of the Exchange Act at the time such information is furnished. 18. Miscellaneous Provisions. An Optionee shall have no rights as a shareholder with respect to any Shares covered by his Option until the date of the issuance of a stock certificate to him for such shares. 19. Other Provisions. The stock option agreement authorized under the Plan shall contain such other provisions, including, without limitation, restrictions upon the exercise of the Option, as the Committee shall deem advisable. Any such stock option agreement shall contain such limitations and restrictions upon the exercise of the Option as shall be necessary in order that such option will be an Incentive Stock Option as defined in Section 422 of the Code if an Incentive Stock Option is intended to be granted. 20. Indemnification of Committee. In addition to such other rights of indemnification as they may have as Directors or as members of the Committee, the members of the Committee shall be indemnified by the Company against the reasonable expenses, including attorneys' fees actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan or any Option granted thereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such Board member is liable for negligence or misconduct in the performance of his duties; provided that within 60 days after institution of any such action, suit or proceeding a Board member shall in writing offer the Company the opportunity, at its own expense, to handle and defend the same. 21. Application of Funds. The proceeds received by the Company from the sale of Common Stock pursuant to Options will be used for general corporate purposes. 22. No Obligation to Exercise Option. The granting of an Option shall impose no obligation upon the Optionee to exercise such Option. 23. Other Compensation Plans. The adoption of the Plan shall not affect any other stock option or incentive or other compensation plans in effect for the Company or any Subsidiary, nor shall the Plan preclude the Company from establishing any other forms of incentive or other compensation for employees and Directors of the Company or any Subsidiary.

(b) Notwithstanding anything to the contrary contained in Section 12.2(a), in the event that at any time after the principal of the Debentures shall so become due and payable and prior to the date of maturity stated in the Debentures all arrears of principal of and interest on the Debentures (with interest at the rate specified in the Debentures on any overdue principal and, to the extent legally enforceable, on any interest overdue) shall be paid by or for the account of the Company, then the holder or holders of 60% of the then outstanding principal amount of the Debentures, by written notice or notices to the Company, may (but shall not be obligated to) waive such Event of Default and its consequences and rescind or annul such declaration, but no such waiver shall extend to or affect any subsequent Event of Default or impair any right resulting therefrom. If any Holder of the Debentures shall give any notice or take any other action with respect to a claimed default, the Company, forthwith upon receipt of such notice or obtaining knowledge of such other action will give written notice thereof to all other Holders of the Debentures, describing such notice or other action and the nature of the claimed default. 12.3. Enforcement In case any one or more Events of Default shall occur and be continuing, each Holder of the Debentures may proceed to protect and enforce the rights of such Holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement in favor of the Purchasers which is contained in any of the Transaction Documents or in such Debenture or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law (including, without limitation, the right to enforce the Company Debenture Collateral, the Guaranties and the Guarantor Debenture Collateral, each in accordance with its respective terms). Each such Holder agrees that it will give written notice to the other Holders of the Debentures prior to instituting any such action. In case of a default in the payment of any principal of or interest on any Debenture, the Company will pay to the holder thereof such further amount as shall be sufficient to cover the cost and the expenses of collection, including, without limitation, reasonable attorney's fees, expenses and disbursements. No course of dealing and no delay on the part of any Holder of the Debentures in exercising any rights shall operate as a waiver thereof or otherwise prejudice such Holder's rights. No right conferred hereby or by any Debenture upon any holder thereof shall be exclusive of any other right referred to herein or therein or now available at law or in equity, by statute or otherwise.

ARTICLE XIII INDEMNIFICATION 13.1. Company Indemnification of Purchasers To the greatest extent permitted by applicable law, the Company agrees to indemnify each Purchaser, its Affiliates and respective legal counsel, and each of the officers, directors, partners and stockholders of each, against and hold it harmless from all Losses arising out of or resulting from: (i) the breach of any representation or warranty of the Company in any Transaction Document or in any agreement, certificate or instrument delivered pursuant thereto; (ii) the breach of any agreement by the Company contained in any Transaction Document or any agreement, certificate of instrument delivered pursuant thereto; or (iii) the Purchasers' representation on the Board of Directors and any committees thereof or as an observer thereon. 13.2. Notice of Claims Anything in Section 13.1 to the contrary notwithstanding, no claim may be asserted nor may any action be commenced against the Company for breach of any representation or warranty contained in this Agreement, unless notice of such Purchaser's intention to assert any such claim or commence any such action is received by the Company describing in writing in reasonable detail the facts and circumstances with respect to the subject matter of such claim or action on or prior to the date on which the representation or warranty on which such claim or action is based ceases to survive as set forth in Section 19.3. With respect to any claim or action as to which such notice shall have been given, the Purchasers shall be entitled to assert a claim or commence an action for indemnification with respect thereto at any time after the giving of such notice, regardless of whether any such claim or action may be asserted or commenced prior to or after the date on which the representation or warranty on which such claim or action is based ceases to survive as set forth in Section 19.3. 13.3. Third Party Claims Each Purchaser agrees to give the Company prompt written notice of any claim, assertion, event or proceeding by a third party of which it has actual knowledge concerning any Losses as to which it intends to request indemnification under this Agreement. The Company shall have the right to direct, through counsel of the Company's own choosing, the defense or settlement of any such claim or proceeding at the Company's own expense. If the Company elects to assume the defense of any such claim or proceeding, such Purchaser may participate in such defense, but in such case the expenses of such Purchaser shall be paid by such Purchaser. Such Purchaser shall cooperate with the Company in the defense or settlement thereof, and the Company shall reimburse such Purchaser for its reasonable out-of-pocket expenses in connection therewith. If the Company elects to direct the defense of any such claim or proceeding, such Purchaser shall not pay, or permit to be paid, any part of any claim or demand arising from such asserted liability, unless the Company consents in writing to such payment or unless the Company, subject to the last sentence of this Section 13.3, withdraws from the defense of such asserted liability, or unless a final judgment from which no appeal may be taken by or on behalf of the Company is entered against such Purchaser for such liability. If the Company shall fail to defend any such claim or proceeding, or if, after commencing or undertaking any defense, fails to prosecute or withdraws from such defense, such Purchaser shall have the right to undertake the defense or settlement thereof, at the Company's expense. If such Purchaser assumes the defense of any such claim or proceeding pursuant to this Section 13.3 and proposes to settle such claim or proceeding prior to a final judgment thereon or to forego appeal with respect thereto, then such Purchaser shall give the Company prompt written notice thereof and the Company shall have the right to participate in the settlement or assume or reassume the defense of such claim or proceeding. 13.4. Purchaser Indemnification of the Company Each Purchaser agrees to indemnify and hold harmless the Company, its Affiliates and respective legal counsel, and each of the officers, directors, partners and stockholders of each, from and against any Losses arising out of the breach of any representation or warranty of such Purchaser in Article V of this Agreement.

ARTICLE XIV AMENDMENT AND WAIVER 14.1. Amendment and Waiver No amendment of any provision of this Agreement, including any amendment of this Article XIV, shall be valid unless the same shall be in writing and signed by the Company (and the Independent Committee) and the holders of 60% of the then outstanding principal amount of the Debentures. No waiver by any party of any default, misrepresentation, or breach of warranty or covenant hereunder or under any other Transaction Document, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or thereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. 14.2. Binding Effect of Amendment and Waiver The Company and each Holder shall be bound by any amendment or waiver effected in accordance with the provisions of this Article XIV, whether or not such Debenture and Share, respectively, shall have been marked to indicate such modification, but any Debenture and Share, respectively, issued thereafter shall bear a notation as to any such modification. Promptly after obtaining the written consent of the Holders of the Debentures and the holders of Shares, respectively, herein provided, the Company shall transmit a copy of such modification to all of the holders of the Debentures and the holders of Shares, respectively, then outstanding. ARTICLE XV EXCHANGE OF DEBENTURES At any time at the request of any Holder to the Company at its office provided under Section 19.6, the Company at its expense (except for any transfer tax or any other tax arising out of the exchange) will issue in exchange therefore new Debentures, in such denomination or denominations ($100,000 or any larger multiple of $100,000, plus one Debenture in a lesser denomination, if required) as such holder may request, in aggregate principal amount equal to the unpaid principal amount of the Debenture or Debentures surrendered and substantially in the form thereof, dated as of the date to which interest has been paid on the Debenture or Debentures surrendered (or, if no interest has yet been so paid thereon, then dated the date of the Debenture or Debentures so surrendered) and payable to such Person or Persons or order as may be designated by such holder. ARTICLE XVI TRANSFER OF DEBENTURES Subject to the next paragraph of this Article XVI, each Holder by acceptance thereof agrees that it will give the Company ten days written notice prior to selling or otherwise disposing of such Debenture. No such sale or other disposition shall be made unless (i) the holder shall have supplied to the Company an opinion of counsel for the holder reasonably acceptable to the Company to the effect that no registration under the Securities Act is required with respect to such sale or other disposition, or (ii) an appropriate registration statement with respect to such sale or other disposition shall have been filed by the Company and declared effective by the SEC. If the Holder has obtained an opinion of counsel reasonably acceptable to the Company to the effect that the sale of its Debenture may be made without registration under the Securities Act pursuant to compliance with Rule 144 (or any successor rule under the Securities Act), the holder need not provide the Company with the notice required in the first paragraph of this Article XVI. G-30

ARTICLE XVII RIGHT OF FIRST REFUSAL; ADDITIONAL INVESTMENT 17.1. Right of First Refusal Each First Refusal Holder shall be entitled to the following right of first refusal: (a) Except in the case of Excluded Securities, the Company shall not issue, sell or exchange, agree to issue, sell or exchange, or reserve or set aside for issuance, sale or exchange any Equity Securities unless in each case, the Company shall have first offered to sell to the First Refusal Holders the Equity Securities at a price and on such other terms as shall have been specified by the Company in writing delivered to each of the First Refusal Holders (the "Offer"), which Offer by its terms shall remain open and irrevocable for a period of 30 days from the date it is delivered by the Company to the First Refusal Holders; provided, however, that such issuance, sale or exchange of Equity Securities shall result in gross proceeds to the Company (whether at the time of issuance or upon conversion, exercise, or exchange thereof) of an amount in excess of $200,000 (the "Minimum Offering Threshold"). For purposes of computing the Minimum Offering Threshold, all offerings, issuances, sales and exchanges of Equity Securities during any rolling 12-month period shall be aggregated. (b) Each of the First Refusal Holders shall have the right to purchase up to its pro rata share of the Equity Securities determined at the time of the consummation of the Company's issuance of Equity Securities. The "pro rata share" of each First Refusal Holder shall be that amount of the Equity Securities multiplied by a fraction, (i) the numerator of which is the sum of (1) the number of shares of Common Stock underlying a Debenture held by such Person if such Person is the holder of a Debenture, (2) the number of shares of Common Stock underlying the 2002 Debentures held by such Person if such Person is an Existing 2002 Debentureholder, (3) the number of shares of Common Stock underlying the 1998 Debentures held by such Person if such Person is an Existing 1998 Debentureholder, and (4) the number of shares of Common Stock issued to such Old Common Holder upon conversion of a 2002 Existing Debenture or 1998 Existing Debenture (as the case may be) if such Person is an Old Common Holder and has converted the Debenture, and (ii) the denominator of which is the sum of (1) the total number of shares of Common Stock underlying the Debentures issued pursuant to this Agreement and (2) the total number of shares of Common Stock underlying the 2002 Debentures and the 1998 Debentures. (c) Notice of the intention of each First Refusal Holder to accept, in whole or in part, an Offer shall be evidenced by a writing signed by such Person, as the case may be and delivered to the Company prior to the end of the 30-day period commencing with the date of such Offer (or, if later, within ten days after the delivery or giving of any written notice of a material change in such Offer), setting forth such portion (specifying number of shares, principal amount or the like) of the Equity Securities such Person elects to purchase (the "Notice of Acceptance"). (d) In the event that all First Refusal Holders do not elect to purchase all of the Equity Securities, the Persons which have provided notice of their intention to exercise the refusal rights as provided in Section 17.1(c) shall have the right to purchase, on a pro rata basis, any unsubscribed portion of the Equity Securities during a period of ten days following the 30-day period provided in Section 17.1(c). Following such additional ten-day period, in the event the First Refusal Holders have not elected to purchase all of the Equity Securities, the Company shall have 90 days from the expiration of the foregoing 40-day period to sell all or any part of such Equity Securities as to which a Notice of Acceptance has not been given by any of such Persons (the "Refused Securities") to any other Person or Persons on the terms provided in the Offer. Upon the closing of the sale to such other Person or Persons of all the Refused Securities, which shall include payment of the purchase price to the Company in accordance with the terms of the Offer, if the First Refusal Holders have timely submitted a Notice of Acceptance, they shall purchase from the Company, and the Company shall sell to such Persons, as the G-31

case may be, the Equity Securities in respect of which a Notice of Acceptance was delivered to the Company, at the terms specified it the Offer. The purchase by the First Refusal Holders of any Equity Securities is subject in all cases to the preparation, execution and delivery by the Company to such Persons of a purchase agreement and other customary documentation relating to such Equity Securities as is satisfactory in form and substance to such Persons and each of their respective counsel. (e) In each case, any Equity Securities not purchased by the First Refusal Holders or by a Person or Persons in accordance with Section 17.1(d) may not be sold or otherwise disposed of until they are again offered to such Persons under the procedures specified in Sections 17.1(a), 17.1(c) and 17.1(d) of this Agreement. (f) The rights of the First Refusal Holders under this Section 17.1 shall not apply to the following securities (the "Excluded Securities"): (i) Common Stock or options to purchase such Common Stock, issued to officers, employees or directors of, or consultants to, the Company, pursuant to any agreement, plan or arrangement approved by the Board of Directors; (ii) Common Stock issued as a stock dividend or upon any stock split or other subdivision or combination of shares of Common Stock; (iii) shares issued upon conversion of the Debentures or the Existing Debentures, exercise of the warrants issued in connection with the issuance of the Existing Debentures or conversion/exercise of other convertible securities outstanding on the date hereof; (iv) any securities issued for consideration other than cash pursuant to a merger, consolidation, acquisition, strategic alliance or similar business combination approved by the Board of Directors and at the Company's Annual Meeting of Stockholders; or (v) any debentures issued in satisfaction of interest payments under the Existing Debentures, including debentures instruments issued in satisfaction of interest payments on those debenture instruments. (g) Notwithstanding anything to the contrary contained herein, a holder of a Debenture (other than an initial Purchaser) shall not be considered a First Refusal Holder for purposes of this Section 17.1 only, unless such Person then holds Debentures with an outstanding principal amount of at least $200,000. ARTICLE XVIII TRANSFER RESTRICTIONS 18.1. Transfer Restrictions This Article XVIII shall apply to all Transfers of Restricted Securities. Notwithstanding any implication to the contrary set forth in this Agreement, no Transfer shall have any force or effect unless: (a) such a Transfer is made in accordance with each of the provisions of this Article XVIII, (b) such a Transfer would not result in the violation of applicable federal or state securities laws, (c) the transferee in any such Transfer is an Accredited Investor, and (d) the intended transferee of such Transfer executes the Joinder Agreement. Any attempt by a Holder to Transfer any Restricted Securities in violation of any provision of this Agreement will be void and have no force or effect. The Company will not be required (i) to transfer on its books any Restricted Securities that have been sold, gifted or otherwise Transferred in violation of this Agreement or (ii) to treat as the owner of such Restricted Securities, or to accord the right to vote or pay principal, interest or dividends to, any purchaser, donee or other transferee to whom such Restricted Securities may have been so Transferred in violation of this Agreement. 18.2. Notice of Proposed Transfer Before any Holder may effect any Transfer of any Offered Securities (other than a Permitted Transfer), such Holder (the "Selling Security Holder") must give written notice concurrently to the Company and the G-32

other Holders ("Seller Notice") stating (a) the Selling Security Holder's bona fide intention to transfer such Offered Securities, (b) the number of the Offered Securities to be Transferred, (c) the name, address and relationship to the Selling Security Holder, if any, of each proposed purchaser or other transferee (the "Proposed Transferee"), (d) the bona fide cash price per Offered Security (the "Offered Price"); and (e) the anticipated date of the proposed Transfer, which shall be a date not earlier than 30 days after the date the Seller Notice is delivered. Upon the request of the Company or a Holder, the Selling Security Holder will promptly furnish such information to the Company and to the Holder as may be reasonably requested to establish that the offer and proposed Transfer are bona fide. 18.3. Purchase Rights With respect to any Transfer by any Selling Security Holder (other than a Permitted Transfer), the Company and each Holder shall have the right to purchase ("Purchase Right") the Offered Securities, exercisable as set forth below: (a) The Company shall have the right to purchase all, but not less than all, of the Offered Securities. If the Company desires to purchase all of the Offered Securities, the Company must, within the 10 day period (the "Company Refusal Period") commencing on the date of receipt of the Seller Notice, give written notice to the Selling Security Holder of the Company's election to purchase the Offered Securities. In the event that the Company elects not to purchase all of the Offered Securities, the Offered Securities may be purchased by the Holders as set forth in Section 18.3(b). On or before the expiration of the Company Refusal Period, the Company will give written notice (the "Company Waiver Notice") to the Holders specifying either (i) that all of the Offered Securities were subscribed by the Company's exercising its Purchase Right or (ii) that the Company waived its Purchase Right. Notwithstanding any failure by the Company to deliver a Company Waiver Notice, a failure by the Company to exercise its Purchase Right within the Company Refusal Period shall be deemed a waiver of such right. (b) In the event the Company does not purchase all of the Offered Securities, each Holder shall have the opportunity to purchase up to such Holder's pro rata share of the Offered Securities. For purposes of this Section 18.3(b), a Holder's pro rata share shall be determined by dividing the number of shares of Common Stock (inclusive of all Common Stock underlying the Restricted Securities) held by such Holder by the total number of shares of Common Stock (inclusive of all Common Stock underlying the Restricted Securities) held by all Holders purchasing Offered Securities pursuant to this Section 18.3(b). If any Holder, or its assignees who are Affiliates of such Holder, desires to purchase the Offered Securities, such Holder must, within a 5 day period (the "Holder Refusal Period") commencing on the later date of (i) the Company Waiver Notice or (ii) the 10th day after the Seller Notice, give written notice ("Holder Notice") to the Selling Security Holder and to the Company of such Holder's election to purchase such Holder's pro rata share of the remaining Offered Securities, or such lesser number as may be stated in such Holder's Holder Notice. The participating Holders also may allocate the right to purchase the Offered Securities between or among them in any proportion they choose as reflected in a notice to the Selling Security Holder within the Holder Refusal Period. In the event that any Holder elects not to purchase any of the Offered Securities, such Holder shall, prior to the expiration of the Holder Refusal Period, give written notice ("Holder Waiver Notice") to the Selling Security Holder that the Holder is waiving such Holder's right to purchase all such Offered Securities under this Section 18.3(b). Notwithstanding any failure by a Holder to deliver a Holder Waiver Notice, a failure by a Holder to exercise such Holder's Purchase Right within the Holder Refusal Period shall be deemed a waiver of such right. (c) The purchase price for the Offered Securities to be purchased by the Company or the Holders exercising their Purchase Right under this Agreement will be the Offered Price, and will be payable within 10 days after the date the Purchase Right is first exercised for all of the Offered Securities. Payment of the purchase price will be made by the exercising Company or Holders (as the case may be) by check or wire transfer of immediately available funds. G-33

(d) If the Company or Holders exercise their Purchase Right to purchase all of the Offered Securities, then, upon consummation of such purchase, the Selling Security Holder will have no further rights as a holder of the Offered Securities except the right to receive payment for the Offered Securities in accordance with the terms of this Agreement, and the Selling Security Holder will promptly cause all certificate(s) or debentures (as the case may be) evidencing such Offered Securities, together with such other instruments and documents of transfer as the Persons acquiring the Offered Securities shall reasonably request, to be surrendered to the Company for Transfer to the Persons acquiring the Offered Securities (free and clear of any and all liens, claims and encumbrances whatsoever except those imposed by this Agreement and securities laws generally). (e) If the Company or the Holders have not elected to purchase all of the Offered Securities, then, subject to the Co-Sale Rights set forth in Section 18.4, the Selling Security Holder may Transfer the remaining Offered Securities to the Proposed Transferee, at the Offered Price or at a higher price, provided that such Transfer (i) is consummated within 90 days after the date of the Seller Notice and (ii) is in accordance with all the terms of this Agreement. Any proposed Transfer at a price or on terms and conditions more favorable than those described in the Seller Notice, as well as any subsequent proposed Transfer of any of the Offered Securities by the Selling Security Holder, shall again be subject to this Section 18.3 and shall require full compliance by the Selling Security Holder with the procedures in this Section 18.3. 18.4. Co-Sale Rights Notwithstanding Section 18.3(e), no Holder (each, a "Co-Sale Seller") shall Transfer any of the Offered Securities pursuant to Section 18.3(e) to a Proposed Transferee until such Co-Sale Seller has given written notice to each of the Holders of the right (the "Co-Sale Right"), exercisable either within 5 days after the date of such Person's Holder Waiver Notice or within 15 business days following receipt of the Seller Notice, whichever is later, to sell to a Proposed Transferee all or part of such Holder's Portion of the Offered Securities, on the same terms and conditions as set forth in the Seller Notice, on an as-converted-to-Common-Stock basis. A Holder may exercise the Co-Sale Right by delivering to the Co-Sale Seller at the closing of the Transfer of Offered Securities to the Proposed Transferee one or more certificates or debentures (as the case may be), properly endorsed for Transfer, representing such Offered Securities to be Transferred by the Holder. At the closing of the Transfer of Offered Securities to the Proposed Transferee, such certificates, debentures or other instruments will be Transferred and delivered to the Proposed Transferee as set forth in the Seller Notice in consummation of the Transfer of the Offered Securities pursuant to the terms and conditions specified in such notice, and the Co-Sale Seller will remit, or will cause the Proposed Transferee to remit, to the participating Holder at closing that portion of the proceeds of the Transfer to which the Holder is entitled by reason of the Holder's participation in such Transfer pursuant to the Co-Sale Right. If the Offered Securities consist of debentures or more than one series or class or type of stock and the Proposed Transferee is not willing to purchase debentures or shares of a class of preferred stock held by the Holders, then the Holders exercising a Co-Sale Right will have the opportunity to convert such Existing Debentures, Debentures or shares of Preferred Stock into Common Stock, and the Company will cooperate to effect such conversion. ARTICLE XIX MISCELLANEOUS 19.1.

Governing Law This Agreement and the rights of the parties hereunder shall be governed in all respects by the laws of the State of New York wherein the terms of this Agreement were negotiated, excluding to the greatest extent permitted by law any rule of law that would cause the application of the laws of any jurisdiction other than the State of New York.

19.7. Delays, Omissions or Waivers No delay or omission to exercise any right, power or remedy accruing to any Holder of the Debentures upon any breach or default of the Company under this Agreement shall impair any such right, power or remedy of such holder nor shall it be construed to be a waiver of any such breach or default, or an acquiescence, therein, or of or in any similar breach or default thereafter occurring. Any permit, consent or approval of any kind or character on the part of any holder of any breach or default under this Agreement must be made in writing and shall be effective only to the extent specifically set forth in such writing.

In addition, all representations and warranties hereunder shall be given independent effect so that if a particular representation or warranty proves to be incorrect or is breached, the fact that another representation or warranty concerning the same or similar subject matter is correct or is not breached will not affect the incorrectness of or a breach of a representation and warranty hereunder. 19.9. Rights and Obligations; Severability Unless otherwise expressly provided herein, each Purchaser's rights and obligations hereunder are several rights and obligations, not rights and obligations jointly held with any other Person. In case any provision of this Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 19.10.

HALSEY DRUG CO., INC. CONVERTIBLE SENIOR SECURED DEBENTURE $ NO. N- FEBRUARY 6, 2004 HALSEY DRUG CO., INC., a corporation organized under the laws of the State of New York (the "Company"), for value received, hereby promises to pay to , or registered assigns (the "Payee" or "Holder"), upon due presentation and surrender of this Debenture, on the Maturity Date, the principal amount of ($ ) and accrued interest thereon as hereinafter provided. As used herein, the "Maturity Date" means July 31, 2004; provided, that (i) the Company may extend the Maturity Date, for a period not to exceed 90 days, to the extent the effectiveness of the Amendment (as defined below) is delayed due to the review of the Proxy Statement (as defined below) by the Securities and Exchange Commission, and (ii) the Holders holding at least the Approval Threshold (as defined below) may extend the Maturity Date from time to time in their sole discretion. This Debenture was issued by the Company pursuant to a certain Debenture and Share Purchase Agreement dated as of February 6, 2004 among the Company and certain purchasers identified therein, including the Payee (together with the Schedules and Exhibits thereto, the "Purchase Agreement") relating to the purchase and sale of Convertible Senior Secured Debentures (the "Debentures"). The holders from time to time of the Debentures (including the Holder) are referred to hereinafter as the "Holders". The Holder is entitled to the benefits of the Purchase Agreement, including, without limitation, the rights upon the occurrence and during the continuance of an Event of Default and the benefits of security interests and guaranties referred to below. Reference is made to the Purchase Agreement and the documents entered into pursuant thereto with respect to certain additional rights of the Holder and obligations of the Company and its Subsidiaries not expressly set forth herein. Capitalized terms used herein but not otherwise defined herein shall have the meaning ascribed thereto in the Purchase Agreement. All such rights and obligations set forth in the Purchase Agreement are incorporated herein by reference. ARTICLE I PAYMENT OF PRINCIPAL AND INTEREST; METHOD OF PAYMENT 1.1. Payment, if any, of the principal and accrued interest on this Debenture shall be made in cash, in immediately available funds, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. Interest (computed on the basis of a 360-day year of twelve 30-day months) shall accrue on the unpaid portion of said principal amount from time to time outstanding at the Stated Interest Rate (as defined below), and shall be paid by the Company to the H-1

Payee on the Maturity Date or earlier acceleration hereof (unless this Debenture, including such accrued interest, is earlier converted pursuant to Article III below). Both principal hereof and interest hereon are payable at the Holder's address above or such other address as the Holder shall designate from time to time by written notice to the Company. The Company will pay or cause to be paid all sums becoming due hereon for principal and interest by check or wire transfer, at the Holder's election, and, without any requirement for the presentation of this Debenture or making any notation thereon, except that the Holder hereof agrees that payment of the final amount due shall be made only upon surrender of this Debenture to the Company for cancellation. Prior to any sale or other disposition of this instrument, the Holder hereof agrees to endorse hereon the amount of principal paid hereon and the last date to which interest has been paid hereon and to notify the Company of the name and address of the transferee. As used herein, the "Stated Interest Rate" means the rate of (i) 1.62% per annum prior to the Maturity Date or earlier acceleration hereof, and (ii) fifteen percent (15%) per annum on and after the Maturity Date or earlier acceleration hereof, in each case subject to the limitations of applicable law. 1.2. If any payment of principal or interest or both shall remain unpaid for a period of two (2) business days or more after the Maturity Date or earlier acceleration hereof a late charge equivalent to five percent (5%) of the unpaid amount shall be charged. In addition, a late charge equivalent to five percent (5%) of the outstanding principal amount and accrued interest shall be charged if this Debenture has not been converted pursuant to Article III before November 1, 2004. 1.3. If this Debenture or any portion hereof becomes due and payable on a Saturday, Sunday or public holiday under the laws of the State of New York, the due date hereof shall be extended to the next succeeding full business day and interest shall be payable at the Stated Rate per annum during such extension. All payments received by the Holder shall be applied first to the payment of all accrued interest payable hereunder. 1.4 Notwithstanding anything to the contrary herein, no Debenture may be prepaid in whole or in part without the prior written consent of Holders holding at least sixty percent (60%) of the aggregate principal amount of the Debentures then outstanding (the "Approval Threshold"). Any such prepayment that is so approved shall be made ratably among the Holders in proportion to the percentage of the aggregate principal amount of the Debentures held by each such Holder. ARTICLE II SECURITY/SUBORDINATION 2.1. The obligations of the Company under this Debenture are secured pursuant to security interests on and collateral assignments of, assets, tangible and intangible, of the Company granted by the Company to the Holder and the other Holders pursuant to a General Security Agreement of even date herewith, and the collateral assignments referred to in the Purchase Agreement. In addition, each of Houba, Inc. ("Houba") and Axiom Pharmaceutical Corporation, each a wholly owned subsidiary of the Company (individually a "Guarantor" and collectively, the "Guarantors"), has executed and delivered in favor of the Holder and the other Holders a Continuing Unconditional Guaranty, dated an even date herewith (each a "Guarantee"), guaranteeing the full and unconditional payment when due of the amounts payable by the Company to the Holder and the other Holders pursuant to the terms of their respective Debentures. The obligations of each Guarantor under its Guaranty are secured (subject to the Subordination Agreement) pursuant to security interests on and collateral assignments of, assets, tangible and intangible, of such Guarantor granted by the Guarantor to the Holder and the other Holders pursuant to a security agreement of even date herewith, and the collateral assignments referred to in the Purchase Agreement. The rights of the Holders with respect to the collateral described in the security agreements and collateral assignments with the Company and the Guarantors as provided in the Purchase Agreement are subject to the terms of an Amended and Restated Subordination Agreement dated of even date herewith by and among the Company, the Holders and the other signatories thereto (the "Subordination Agreement"). H-2

ARTICLE III CONVERSION 3.1. At 12:01 a.m. (New York time) on the first day after the effectiveness of the Amendment (the "Conversion Date"), so long as no Conversion Default (as defined below) is then existing, the entire principal amount hereof and all accrued interest hereon (through and including the day prior to the Conversion Date) shall automatically convert into shares of Series A Convertible Preferred Stock of the Company at a conversion price equal to $0.6425 per share, as such conversion price may be adjusted as provided in Section 3.4 hereof (as so adjusted, the "Conversion Price"). Promptly thereafter the Company shall deliver a notice to each Holder that shall (i) state the date of the Conversion Date, (ii) include any disclosures required by law, (iii) include a copy of the Amendment accepted by the Secretary of State of New York, (iv) specify the exact amount of principal and accrued interest that was converted in accordance with this Section 3.1 and the number of shares to be issued in conversion thereof, (v) state the place where the Debenture shall be delivered for cancellation, and (vi) include any other instructions that Holders must follow in order to tender their Debentures in exchange for certificates for Series A Convertible Preferred Stock. An affidavit of the Secretary or an Assistant Secretary of the Company or an agent employed by the Company that notice of conversion has been mailed postage prepaid to the last address of the Holder appearing on the Debenture registry books kept by the Company shall, in the absence of fraud, be prima facie evidence of the facts stated therein. On and after the Conversion Date, except as provided in the next sentence, Holders of the Debentures shall have no further rights except to receive, upon surrender of the Debentures, a certificate or certificates for the number of shares of Series A Convertible Preferred Stock as to which the Debenture shall have been converted. No fractional shares or scrip representing fractional shares will be issued upon any conversion, with the calculation of the number of shares of Series A Convertible Preferred Stock rounded to the nearest whole share. As used herein, "Conversion Default" means an Event of Default under Section 12.1(e), 12.1(h), 12.1(i) or 12.1(l) of the Purchase Agreement. 3.2. Registration of Transfer; Conversion Procedure. The Company shall maintain books for the transfer and registration of the Debentures. Upon the transfer of any Debenture in accordance with the provisions of the Purchase Agreement, the Company shall issue and register the Debenture in the names of the new Holders. The Debentures shall be signed manually by the Chairman, Chief Executive Officer, President or any Vice President and the Secretary or Assistant Secretary of the Company. Subject to the terms of this Debenture, not later than three (3) days following the surrender of this Debenture the Company shall issue and deliver to or upon the written order of the Holder of such Debenture and in such name or names as such Holder may designate, a certificate or certificates for the number of full shares of Series A Convertible Preferred Stock due to such Holder upon the conversion of this Debenture. Such certificate or certificates shall be deemed to have been issued and any person so designated to be named therein shall be deemed to have become the Holder of record of such Shares as of the Conversion Date. The Company will comply with all securities laws regulating the offer and delivery of the Series A Convertible Preferred Stock upon conversion of the Debentures. 3.3. Company to Provide Series A Convertible Preferred Stock. In accordance with the provisions of the Purchase Agreement, the Company covenants to take certain actions, including to seek the approval of its shareholders and directors, to amend and restate its Certificate of Incorporation in the form attached as Exhibit D to the Purchase Agreement (the "Amendment"), including filing the Proxy Statement described in the Purchase Agreement (the "Proxy Statement"). 3.4. Adjustments to Conversion Price. In order to prevent dilution of the conversion rights granted hereunder, the Conversion Price shall be subject to adjustment from time to time in accordance with this Section 3.4. The Conversion Price in effect at the time of the exercise of conversion rights hereunder shall be subject to adjustment from time to time as follows: (a) If the Company shall grant or issue any shares of Common Stock, or grant or issue any rights or options for the purchase of, or stock or other securities convertible into, Common Stock (such convertible H-3

stock or securities being herein collectively referred to as "Convertible Securities") for a consideration per share which is less than the Conversion Price in effect immediately prior to such issuance or sale (the "Applicable Conversion Price"), then the Applicable Conversion Price in effect immediately prior to such issuance or sale shall, and thereafter, upon each issuance or sale for a consideration per share which is less than the Applicable Conversion Price, the Applicable Conversion Price shall, simultaneously with such issuance or sale, be adjusted, so that such Applicable Conversion Price shall equal (A) the price per share received by the Company, in the case of the issuance of Common Stock by the Company, or (B) the exercise or conversion price of the Convertible Securities issued by the Company, as applicable. (b) Anything in this Section 3.4 to the contrary notwithstanding, no adjustment in the Conversion Price shall be made in connection with: (i) the grant, issuance or exercise of any Convertible Securities pursuant to the Company's qualified or non-qualified Employee Stock Option Plans or any other bona fide employee benefit plan or incentive arrangement, adopted or approved by the Company's Board of Directors or approved by the Company's shareholders, as each may be amended from time to time, or under any other bona fide employee benefit plan hereafter adopted by the Company's Board of Directors; or (ii) the grant, issuance or exercise of any Convertible Securities in connection with the hire or retention of any officer, director or key employee of the Company, provided such grant is approved by the Company's Board of Directors; or (iii) the issuance of any Preferred Stock issued in satisfaction of interest payments on the Debentures and the Existing Debentures, as provided in the Debenture Conversion Agreement; or (iv) the issuance of any Common Stock issued in satisfaction of interest on the Company's indebtedness for borrowed money, provided the number of shares of Common Stock issuable is based on the average closing bid and asked prices for the Common Stock for the twenty (20) trading days preceding the interest payment; or (v) the issuance of any shares of Common Stock pursuant to the grant or exercise of Convertible Securities outstanding as of the date hereof (exclusive of any subsequent amendments thereto). (c) For the purpose of Subsections 3.4, the following provisions shall also be applied: (i) In case of the issuance or sale of additional shares of Common Stock for cash, the consideration received by the Company therefor shall be deemed to be the amount of cash received by the Company for such shares, before deducting therefrom any commissions, compensation or other expenses paid or incurred by the Company for any underwriting of, or otherwise in connection with, the issuance or sale of such shares. (ii) In the case of the issuance of Convertible Securities, the consideration received by the Company therefor shall be deemed to be the amount of cash, if any, received by the Company for the issuance of such rights or options, plus the minimum amounts of cash and fair value of other consideration, if any, payable to the Company upon the exercise of such rights or options or payable to the Company upon conversion of such Convertible Securities. (iii) In the case of the issuance of shares of Common Stock or Convertible Securities for a consideration in whole or in part, other than cash, the consideration other than cash shall be deemed to be the fair market value thereof as reasonably determined in good faith by the Board of Directors of the Company (irrespective of accounting treatment thereof); provided, however, that if such consideration consists of the cancellation of debt issued by the Company, the consideration shall be deemed to be the amount the Company received upon issuance of such debt (gross proceeds) plus accrued interest and, in the case of original issue discount or zero coupon indebtedness, accrued value to the date of such cancellation, but not including any premium or discount at which the debt may then be trading or which might otherwise be appropriate for such class of debt. H-4

(iv) In case of the issuance of additional shares of Common Stock upon the conversion or exchange of any obligations (other than Convertible Securities), the amount of the consideration received by the Company for such Common Stock shall be deemed to be the consideration received by the Company for such obligations or shares so converted or exchanged, before deducting from such consideration so received by the Company any expenses or commissions or compensation incurred or paid by the Company for any underwriting of, or otherwise in connection with, the issuance or sale of such obligations or shares, plus any consideration received by the Company in connection with such conversion or exchange other than a payment in adjustment of interest and dividends. If obligations or shares of the same class or series of a class as the obligations or shares so converted or exchanged have been originally issued for different amounts of consideration, then the amount of consideration received by the Company upon the original issuance of each of the obligations or shares so converted or exchanged shall be deemed to be the average amount of the consideration received by the Company upon the original issuance of all such obligations or shares. The amount of consideration received by the Company upon the original issuance of the obligations or shares so converted or exchanged and the amount of the consideration, if any, other than such obligations or shares, received by the Company upon such conversion or exchange shall be determined in the same manner as provided in paragraphs (i) and (ii) above with respect to the consideration received by the Company in case of the issuance of additional shares of Common Stock or Convertible Securities. (v) In the case of the issuance of additional shares of Common Stock as a dividend, the aggregate number of shares of Common Stock issued in payment of such dividend shall be deemed to have been issued at the close of business on the record date fixed for the determination of stockholders entitled to such dividend and shall be deemed to have been issued without consideration; provided, however, that if the Company, after fixing such record date, shall legally abandon its plan to so issue Common Stock as a dividend, no adjustment of the Applicable Conversion Price shall be required by reason of the fixing of such record date. (d) For purposes of the adjustment provided for in Section 3.4, if at any time the Company shall issue any Convertible Securities, the Company shall be deemed to have issued at the time of the issuance of such Convertible Securities the maximum number of shares of Common Stock issuable upon conversion of the total amount of such Convertible Securities. (e) On the expiration, cancellation or redemption of any Convertible Securities, the Conversion Price then in effect hereunder shall forthwith be readjusted to such Conversion Price as would have been obtained (i) had the adjustments made upon the issuance or sale of such expired, canceled or redeemed Convertible Securities been made upon the basis of the issuance of only the number of shares of Common Stock theretofore actually delivered upon the exercise or conversion of such Convertible Securities (and the total consideration received therefor) and (ii) had all subsequent adjustments been made on only the basis of the Conversion Price as readjusted under this subsection 3.4(e) for all transactions (which would have affected such adjusted Conversion Price) made after the issuance or sale of such Convertible Securities. (f) Anything in this Section 3.4 to the contrary notwithstanding, no adjustment in the Conversion Price shall be required unless such adjustment would require an increase or decrease of at least one cent per share in such Conversion Price; provided, however, that any adjustments which by reason of this subsection 3.4(f) are not required to be made shall be carried forward and taken into account in making subsequent adjustments. All calculations under this Section 3.4 shall be made to the nearest cent. (g) Upon any adjustment of any Conversion Price, then and in each such case the Company shall promptly deliver a notice to the registered Holder of this Debenture, which notice shall state the Conversion Price resulting from such adjustment, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. 3.5. Reorganization of the Company. If the Company is a party to a merger or other transaction which reclassifies or changes its outstanding Common Stock, upon consummation of such transaction this Debenture H-5

shall automatically become convertible into the kind and amount of securities, cash or other assets which the Holder of this Debenture would have owned immediately after such transaction if the Holder had converted this Debenture at the Conversion Price in effect immediately before the effective date of the transaction. Concurrently with the consummation of such transaction, the person obligated to issue securities or deliver cash or other assets upon conversion of this Debenture shall execute and deliver to the Holder a supplemental Debenture so providing and further providing for adjustments which shall be as nearly equivalent as may be practical to the adjustments provided in this Article 3. The successor Company shall mail to the Holder a notice describing the supplemental Debenture. ARTICLE IV MISCELLANEOUS 4.1. Default. Upon the occurrence of any one or more of the Events of Default specified in the Purchase Agreement all amounts then remaining unpaid on this Debenture may be declared to be, or automatically become, immediately due and payable as provided in the Purchase Agreement. 4.2. Collection Costs. In the event that this Debenture shall be placed in the hands of an attorney for collection by reason of any event of default hereunder, the undersigned agrees to pay reasonable attorney's fees and disbursements and other reasonable expenses incurred by the Holder in connection with the collection of this Debenture. 4.3. Rights Cumulative; Specific Performances. The rights, powers and remedies given to the Payee under this Debenture shall be in addition to all rights, powers and remedies given to it by virtue of the Purchase Agreement, any document or instrument executed in connection therewith, or any statute or rule of law. Without limiting the generality of the foregoing, the Company and Holder acknowledge and agree that the transactions contemplated by this Debenture are unique. Accordingly, the Company acknowledges and agrees that in addition to the other remedies to which the Holder may be entitled, the Holder shall be entitled to a decree of a specific performance and injunctive and other equitable relief to require the Company's compliance with its obligations hereunder. 4.4. No Waivers. Any forbearance, failure or delay by the Payee in exercising any right, power or remedy under this Debenture, the Purchase Agreement, any documents or instruments executed in connection therewith or otherwise available to the Payee shall not be deemed to be a waiver of such right, power or remedy, nor shall any single or partial exercise of any right, power or remedy preclude the further exercise thereof. 4.5. Amendments in Writing. Subject to the terms of the Purchase Agreement, no amendment, modification or waiver of any provision of this Debenture shall be effective unless it shall be in writing and signed by the Holders holding at least the Approval Threshold, and any such amendment, modification or waiver shall apply only in the specific instance for which given. Each such amendment, modification or waiver that is approved shall apply to each Debenture. 4.6. Governing Law; Jurisdiction. (a) This Debenture and the rights of the holders hereof shall be governed by, and construed in accordance with, the laws of the State of New York wherein the terms of this Debenture were negotiated, excluding to the greatest extent permitted by law any rule of law that would cause the application of the laws of any jurisdiction other than the State of New York. (b) The undersigned hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or United States Federal court sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Debenture or for recognition or enforcement of any judgment, and each of the parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted by law, in such United States Federal court. The undersigned agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or any other manner provided by H-6

law. Nothing in this Debenture or any other Transaction Document shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Debenture or any of the other Transaction Documents in the courts of any jurisdiction. (c) The Company irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or in relation to this Debenture or any other transaction document to which it is a party in any such New York State or United States Federal Court. The Company hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 4.7. No Counterclaims. The Company waives the right to interpose counterclaims or set-offs of any kind and description in any litigation arising hereunder (whether or not arising out of or relating to this Debenture). 4.8.

Mutilated, Lost, Stolen or Destroyed Debentures. In case this Debenture shall be mutilated, lost, stolen or destroyed, the Company shall issue and deliver in exchange and substitution for and upon cancellation of the mutilated Debenture, or in lieu of and substitution for the Debenture, mutilated, lost, stolen or destroyed, a new Debenture of like tenor and representing an equivalent right or interest, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and an indemnity, if requested, also reasonably satisfactory to it (but without requirement of posting any bond). 4.12. Maintenance of Office. The Company covenants and agrees that so long as this Debenture shall be outstanding, it will maintain an office or agency in New York (or such other place as the Company may designate in writing to the holder of this Debenture) where notices, presentations and demands to or upon the Company in respect of this Debenture may be given or made. 4.13. WAIVER OF JURY TRIAL. THE COMPANY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS DEBENTURE OR ANY OTHER TRANSACTION DOCUMENT TO WHICH IT IS A PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

Each Party agrees that it shall not communicate such Confidential Information except to its employees, advisors, representatives and contractors who have a need to know it. Each Party shall ensure that any employees, advisors, representatives or contractors who are placed in a position to learn such Confidential Information will have been previously made aware of the terms of this Agreement, have employment agreements or other agreements obligating them to keep such information confidential consistent with the terms of this Agreement and each Party shall indemnify the other Party against the misuse of such Confidential Information by its employees, advisors, representatives or contractors. For the avoidance of doubt, the Purchaser shall be under no obligation to maintain the confidentiality of any of the Confidential Asset Information and it may use and disclose the Confidential Asset Information in any manner it chooses in its sole discretion. (c) The obligations of confidentiality and nondisclosure shall not apply to Confidential Information which: (i) at the time of disclosure is in the public domain; (ii) after disclosure becomes part of the public domain through no act or omission by the receiving Party; or (iii) a Party hereto is compelled to disclose by a court or other tribunal of competent jurisdiction. In this case, the compelled Party shall give the disclosing Party prompt notice so that the disclosing Party can seek a protective order, and shall exercise reasonable efforts to ensure that the information is accorded confidential treatment by the court or other tribunal. (d) The obligations of confidentiality and nondisclosure shall not apply to Confidential Party Information which: (i) as shown by written records or other competent proof was in the possession of the receiving Party prior to disclosure or development under this Agreement; (ii) is rightly received by the receiving Party, without obligation of secrecy, from a Third Party who was entitled to receive and transfer such; or (iii) as shown by written records or other competent proof is independently developed by employees of the receiving Party who did not have access to Confidential Information. (e) A Party shall also be entitled to disclose Confidential Asset Information or the other Party's Confidential Party Information, as the case may be (i) that is required to be disclosed in compliance with applicable laws or by order of any governmental body or a court of competent jurisdiction; (ii) as may be necessary or appropriate in connection with the enforcement of this Agreement; (iii) as required in furtherance of a Party's obligations under this Agreement or the Related Agreements; (iv) as necessary or appropriate in connection with disclosures or filings made with the FDA or other Governmental Authorities relating to the Business or the Purchaser's ownership of the Acquired Assets, manufacture of the Products, operation and use of the Facilities, the Halsey Equipment or the Par Equipment (in each case, including, without limitation, with respect to any Retained Information); (v) as may be necessary to Third Parties in connection with business transactions with the Parties, provided, that such Third Parties shall be bound by a confidentiality agreement obligating them to keep such information confidential consistent with the terms of this Agreement; and (vi) as may be required otherwise provided that a Party give the other Party an outline of the material to be disclosed and such other Party shall consent to such disclosure; provided, that the Party required to disclose such information shall use commercially reasonable efforts to obtain confidential I-31

treatment of such information by the agency or court or other disclosee to the maximum permitted extent under law, and that, in the case of disclosure under (i) shall provide the other Party with a copy of the proposed disclosure in sufficient time to allow reasonable opportunity to comment thereon. (f) Each Party shall be entitled, in addition to any other right or remedy it may have, at law or in equity, to an injunction, without the posting of any bond or other security, enjoining or restraining any other Party from any violation or threatened violation of this Section 5.3. 5.4.

In each case, the Seller shall promptly provide to the Purchaser evidence of the Seller having made such payments. Furthermore, with respect to any such payments to be made with respect to the First Closing which have not been made by the Second Closing Date and to the extent of any breach of Section 3.17, the Purchaser shall be entitled to set off against the amounts that would otherwise by due to the Seller at the Second Closing such payment amounts and tax liabilities, as the case may be. 5.5.

Unless disclosure is required by applicable law, no Party shall disclose the Purchase Price or any payment thereof. 5.6. Further Assurances.

I-32

Without limiting the generality of the foregoing, from the First Closing Date until Shareholder Approval: (a) Halsey shall not file a registration statement under the Securities Act other than (i) an amendment to a Form S-8 that has been filed as of the First Closing Date, and (ii) pursuant to demand registration rights held by a Third Party on or prior to the First Closing Date; (b) Halsey shall not, directly or indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition of ) any of its or its Affiliates equity or equity equivalent securities, including without limitation any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable or exercisable for the common stock of Halsey or Voting Securities if such securities have voting rights; (c) Halsey shall issue, if at all, no more than 10,500,000 of its authorized, reserved shares of common stock to any of its existing shareholders, option holders and warrant holders listed, and in any case shall issue no more than its currently authorized 80,000,000 shares of common stock until after Shareholder Approval; and (d) Halsey shall not subdivide (by any stock split, stock dividend, recapitalization or otherwise) any outstanding shares of its common stock into a greater number of shares.

Inspection. The Purchaser shall notify the Seller of the date on which the Purchaser shall take a final physical asset count of the Halsey Equipment and the Par Equipment (the "Final Asset Measurement Date"), which date shall be within 30 days following the First Closing Date. The Seller shall have the right (but not the obligation) to observe and jointly perform such count together with the Purchaser. On the Final Asset Measurement Date, with or without the Seller, a physical asset count shall be conducted by the Purchaser in order to determine the amount of asset shortfall, if any, in the Halsey Equipment and the Par Equipment as of the Final Asset Measurement Date (the "Closing Asset Shortfall"). Promptly upon completion of the final physical asset count, the Purchaser shall determine if any items are missing from the Halsey Equipment or the Par Equipment which are listed on Exhibit C and Exhibit K, respectively, and if there are missing items, then the Purchaser and the Seller shall jointly determine in good faith the value of the Closing Asset Shortfall.

In the event the Purchaser and the Seller can not agree on the Closing Asset Shortfall and the value thereof within 30 days following the Final Asset Measurement Date or such later time as mutually agreed by the Parties, then the Purchaser and the Seller hereby agree to submit such dispute to a internationally recognized independent auditing firm or mutually agreeable appraiser that is not then engaged by either Party for assurance services (the "Auditor"), and the Auditor shall promptly (but in any event no later than by the Second Closing) determine the aspects of the Closing Asset Shortfall and the value thereof which have not been agreed to based upon evidence on the presence or absence of such items and the fair market value thereof, and such determination shall be binding and final, and the Seller shall promptly pay to the Purchaser the full amount of the value of the Closing Asset Shortfall. 5.12. Insurance. The Seller shall maintain, at its expense, products liability and general liability "tail coverage" naming the Purchaser as additional insured, having a limit of not less than Five Million Dollars ($5,000,000) in the I-33

aggregate, for a period from the date hereof until three (3) years from the Second Closing Date, covering the Products manufactured or sold by the Seller on or prior to the First Closing. The Seller shall provide to the Purchaser 30 days prior written notice of any cancellation or change in the foregoing coverage. Upon request of the Purchaser, the Seller shall provide to the Purchaser certificates of insurance evidencing the foregoing coverage. 5.13. Removal of Inventory. If on or prior to the First Closing Date Halsey fails to remove any assets, furniture, chemicals and other materials or documents at either Facility which are not included in the Acquired Assets or the Par Equipment, including, without limitation, the Inventory, then the Purchaser may, at its option and in its sole discretion, (a) require Halsey to complete the removal of such assets, furniture, chemicals and other materials and documents, or (b) remove such assets, furniture, chemicals and other materials and documents itself and Halsey shall immediately pay the Purchaser its fully burden cost of having such items removed from the Facilities and properly disposed of, and if such payment is not received prior to the Second Closing, then set off against and reduce the Second Closing Payment such amounts which are due under this Section 5.13.

Procedures. (a) In order for a Party (the "Indemnified Party") to be entitled to the indemnification provided for under this Agreement in respect of, arising out of or involving a claim made by any Person against the Indemnified Party (a "Third Party Claim"), such Indemnified Party must notify the indemnifying Party (the "Indemnifying Party") in writing (and in reasonable detail) of the Third Party Claim promptly, and in any event within 10 business days after receipt by such Indemnified Party of notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within 10 business days' after the Indemnified Party's receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim. (b) If a Third Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and, if it so elects by giving written notice of such election to the Indemnified Party within 10 business days of its receipt of the Indemnified Party's notification of the Third Party Claim, to assume the defense thereof with counsel reasonably acceptable to the Indemnifying Party; provided, that no Indemnifying Party may so assume such defense unless it also acknowledges to the Indemnified Party in writing that it is obligated to indemnify the Indemnified Party against any Losses arising from such Third Party Claim as provided herein. Should the Indemnifying Party so elect to assume the defense of a Third Party Claim, the so long as the Indemnifying Party diligently conducts such defense it shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying I-37

Party shall control such defense. The Indemnifying Party shall be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof (other than during any period in which the Indemnified Party shall have failed to give notice of the Third Party Claim as provided above). Whether or not the Indemnifying Party chooses to defend a Third Party Claim, all Parties shall cooperate in the defense thereof. Such cooperation shall include the retention and (upon the request of the Party defending the Third Party Claim) the provision to the Party defending the Third Party Claim of records and information that are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnifying Party's prior written consent (which consent shall not be unreasonably withheld). If the Indemnifying Party does not assume the defense of a Third Party Claim, the Indemnified Party may settle, compromise or discharge, such Third Party Claim without the Indemnifying Party's prior written consent, and the Indemnifying Party shall be obligated to indemnify the Indemnified Party for any Losses (including amounts paid in settlement) incurred by the Indemnified Party which result from such Third Party Claim to the extent such Losses are covered by the terms of the indemnities contained in Sections 8.3 or 8.4 (as applicable) If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of a Third Party Claim that the Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the liability in connection with such Third Party Claim, which releases the Indemnified Party completely in connection with such Third Party Claim and that would not otherwise adversely affect the Indemnified Party. (c) In the event any Indemnified Party should have a claim against any Indemnifying Party under Sections 8.3 or 8.4 that does not involve a Third Party Claim being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver notice of such claim with reasonable promptness to the Indemnifying Party. The failure by any Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party under Sections 8.3 or 8.4, except to the extent that the Indemnifying Party demonstrates that it has been prejudiced by such failure. If the Indemnifying Party disputes its liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction. 8.6. Limitation; Exclusions from Limitation. Notwithstanding anything to the contrary contained herein, but except as provided below in this Section 8.6, the Seller's aggregate liability to the Purchaser for Losses under Section 8.3(a) will in no event exceed Two Million Five Hundred Thousand Dollars ($2,500,000). The foregoing limitation on the Seller's liability shall not apply to, and the calculation of the Seller's aggregate liability under such limitation shall not include, any Losses resulting from a breach of the representations and warranties made by Seller under (i) Section 3.17, or (ii) Sections 3.14, 3.15 or 3.16. SECTION 9 TERMINATION 9.1. Termination prior to Second Closing Date. This Agreement may be terminated at any time prior to the Second Closing Date: (a) by mutual written consent of the Parties; (b) by either Party sending notice to the other Party if a Governmental Authority shall have issued an injunction, order, decree or ruling or taken any other action that permanently restrains, enjoins, or otherwise prohibits the transactions contemplated by this Agreement and such injunction, order, decree, I-38

ruling or other actions shall have become final and nonappealable; provided that the Party seeking to terminate this Agreement pursuant to this Section 9.1(b) shall not have taken any action, or failed to take any action, that would cause it to be in breach of any of its agreements, representations, warranties or covenants set forth in this Agreement; (c) by the Purchaser in the event the Second Closing Date does not occur on or before 10 business days following the date of Shareholder Approval, if and when the Purchaser so elects in its sole discretion by sending notice to the Seller of such election; provided, however, that the Purchaser will have no right to terminate this Agreement pursuant to this Section 9.1(c) if, as of the close of the 10th business day following the date of Stockholder Approval, the Seller has fulfilled all of its obligations under this Agreement and is not then in breach of any obligation under the Agreement, including, without limitation, taking or causing to be taken all actions required under Section 2.6(b), delivery of all documents and agreements required under Section 2.6(b), complete performance of all covenants pursuant to Section 5, and all conditions to the obligations of the Purchaser set forth in Section 6.2 with respect to the Second Closing shall have been satisfied; or (d) by either Party by sending notice to the other Party on or after January 1, 2005 in the event that (i) by January 1, 2005 Shareholder Approval has not been obtained and (ii) a meeting of Halsey's shareholders has been held during which Shareholder Approval of the Transactions Requiring Shareholder Approval was considered. 9.2. Effectiveness and Effects of Termination. The termination of this Agreement in accordance with Sections 2.11 or 9.1 shall be effective upon notice of such termination being given the by the terminating Party to the other Party.

The Use and License Agreement may not be terminated by the Seller with respect to the Non-Packaging Assets unless and until this Agreement is terminated in accordance with this Section 9 and the Seller pays to the Purchaser the full amount of the Refundable Amount as well as any other amounts which are then due and payable by the Seller to the Purchaser under this Agreement or any Related Agreement. Notwithstanding the foregoing, with respect to the Packaging Equipment, the Use and License Agreement shall survive any such termination of this Agreement. Furthermore, following such termination of this Agreement: (a) The Parties shall have no further liability hereunder with respect to the Second Closing except that each Party shall remain liable to the other for any breach by it of this Agreement or, for the applicable time periods set forth in Section 8, of any representation, warranty or covenant contained herein occurring before the date of such termination; (b) The transactions contemplated by the First Closing shall remain unaffected and shall not be terminated or revoked in any way, other than the return to the Purchaser of the Refundable Amount; (c) Notwithstanding Section 8.2(a), Sections 2.1(b), 2.6, 2.9(b), 2.10 and 2.11 shall not survive such termination. Notwithstanding Section 8.2(a), Section 5 shall not survive such termination other than Sections 5.2 (for 2 years following such termination), 5.3, 5.4 and 5.6, 5.12 and 5.13, each of which shall survive any such termination of this Agreement, and 5.7 and 5.10, each of which shall survive any such termination of this Agreement until all amounts owed and obligations secured by the Security Agreement have been paid in full to the Purchaser by the Seller. Sections 9.3, 10.7, 10.12, 10.13, 10.14, 10.15 and 10.16 shall survive any such termination; and (d) Termination, relinquishment or expiration of this Agreement for any reason shall be without prejudice to any rights, claims or amounts owed that shall have accrued to the benefit of either Party prior to such termination, relinquishment or expiration. Such termination, relinquishment or expiration shall not relieve either Party from obligations that are expressly indicated to survive termination or expiration of this Agreement. I-39

9.3. Limitation on the Purchaser's Liability. In no event shall the Purchaser or its Affiliates have any liability to the Seller, if any at all, in excess of the Purchase Price. In no event shall the Purchaser have any liability to the Seller for any other actual, special, consequential or punitive damages, and any claim, right, cause of action or liability for any damages that are special, consequential or punitive or for specific performance of this Agreement is hereby fully released and forever discharged.

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements herein contained, the Parties hereto agree as follows: 1. Amendment to Company's Certificate of Incorporation. At the Company's next upcoming meeting of Shareholders, each Party hereto will vote all (x) shares of Common Stock, (y) 5% Convertible Senior Secured Debentures issued pursuant to that certain Debenture and Warrant Purchase Agreement dated March 10, 1998 between the Company and the purchasers listed on the signature page thereto, as amended (the "1998 Debentures"), and (z) 5% Convertible Senior Secured Debentures issued pursuant to that certain Debenture and Warrant Purchase Agreement dated May 26, 1999 between the Company and the purchasers listed on the signature page thereto, as amended (the "1999 Debentures"), then owned by such Party in favor of the following proposed amendments to the Company's Certificate of Incorporation: (a) Increasing the number of shares of the Company's Common Stock authorized for issuance from 80,000,000 to 650,000,000 shares; (b) Providing authorization to issue up to 45,000,000 shares of Series A Preferred having the rights and preferences provided in the Amended and Restated Certificate of Incorporation attached as Exhibit D to the Purchase Agreement; (c) Providing authorization to issue up to 25,000,000 shares of Series B Preferred having the rights and preferences provided in the Amended and Restated Certificate of Incorporation attached as Exhibit A to the Conversion Agreement; and (d) Providing authorization to issue up to 220,000,000 shares of Series C Preferred (consisting of up to 70,000,000 shares of Series C-1 Preferred, 50,000,000 shares of Series C-2 Preferred and 100,000,000 shares of Series C-3 Preferred) having the rights and preferences provided in the Amended and Restated Certificate of Incorporation attached as Exhibit A to the Conversion Agreement. 2. Election of Director Nominees. Commencing upon the Company's next upcoming meeting of shareholders, each Party and Care Capital, Essex and Galen (each of Care Capital, Essex and Galen being referred to herein as a "Designating Party") agree as follows: (a) Each Party holding Common Stock, 1998 Debentures, 1999 Debentures, Series A Preferred, Series B Preferred and Series C Preferred (collectively, the "Securities") shall vote its Securities, and take or cause to be taken such other actions, as may be required from time to time to (i) ensure that the Board of Directors consists of no more than seven directors, and (ii) elect to the Board of Directors of the Company (A) one person designated by each Designating Party, (B) one person designated collectively by Care Capital, Essex and Galen by consent of at least two (2) of such three (3) entities (the "Group Designating Party") (C) one person who shall be the Chief Executive Officer of the Company, and (D) two persons who shall be independent directors (as defined in Rule 4200(a)(15) of the National Association of Securities' Dealers Listing Standards, as may be modified or supplemented) nominated and elected to the Board of Directors by the then current directors. Without limiting the generality of the foregoing, at each annual meeting of the shareholders of the Company, and at each special meeting of the shareholders and debentureholders of the Company called for the purpose of electing directors of the Company, and at any time at which the shareholders and debentureholders of the Company have the right to elect directors of the Company, in each such event, each Party shall vote all Securities owned by them (or shall consent in writing in lieu of a meeting of shareholders and debentureholders of the Company, as the case may be), or take such other actions as shall be necessary, to elect the Designating Party's designee and the Group Designating Party's designee as a director of the Company in accordance with the preceding provisions of this Section 2(a); (b) Each Party shall take all actions necessary to remove forthwith the director designated by a Designating Party or the Group Designating Party when such removal is requested for any reason, with or without cause, by such Designating Party or the Group Designating Party. In the case of the death, resignation or removal as herein provided of a Designating Party's designee or the Group Designating Party's designee, each Party shall vote all Securities held by it to elect another person designated by such Designating Party or the Group Designating Party pursuant to Section 2(a); J-2

(c) Each Party hereby agrees that it will not vote any of its Securities in favor of the removal of any director that shall have been designated by a Designating Party or the Group Designating Party, unless the Designating Party or the Group Designating Party that has designated such director shall have consented to such removal in writing. In the event that any Party shall fail to vote the Securities held by it in accordance with Section 2(a) and (b), such Party shall, upon such failure to so vote, be deemed immediately to have granted to each Designating Party or the Group Designating Party, as applicable, a proxy to vote its Securities solely for the election of the nominee of such Designating Party or the Group Designating Party, as applicable, or the removal of such Designating Party's or the Group Designating Party's designated director, as the case may be. Such Party acknowledges that each such proxy granted hereby, including any successive proxy, if necessary, is being given to secure the performance of an obligation hereunder, is coupled with an interest, and shall be irrevocable until such obligation is performed; (d) No Party shall grant any proxy or enter into or agree to be bound by any voting trust with respect to the Securities held by such Party, or enter into any shareholder agreement or arrangement of any kind with any person with respect to the Securities held by such person that is, in either case, inconsistent with the terms of this Agreement (whether or not such agreement and arrangement was or is with other shareholders of the Company that are or are not parties to this Agreement); (e) The Company shall take, or cause to be taken, such actions as may be required from time to time to establish and maintain executive, audit and compensation committees of the Board of Directors, as well as such other committees of the boards of directors of the Company as the Board of Directors shall determine, having such duties and responsibilities as are customary for such committees. The designees of each Designating Party and the Group Designating Party shall be, if so requested by such Designating Party or the Group Designating Party, in its sole discretion, a member of each such committee; and (f) The rights and obligations provided in this Section 2 shall be applied separately for each Designating Party and for the Group Designating Party. The rights of a Designating Party shall terminate on the date such Designating Party ceases to be a holder of the Minimum Threshold (but only after the conversion of the 2004 Debentures). The right of a Designating Party to be a member of the Group Designating Party shall terminate on the date such Designating Party ceases to be a holder of the Minimum Threshold (but only after the conversion of the 2004 Debentures). For purposes hereof, "Minimum Threshold" shall mean at least 50% of the shares of Series A Preferred issued to such Designating Party upon conversion of its 2004 Debentures (or at least 50% of the shares of Common Stock issued upon conversion thereof). 3. Liability. No Party who shall vote or consent or withhold consent or make a request with respect to any Securities subject to this Agreement on, to or from any matter in compliance with the terms hereof that shall, as a result of any such vote or consent or withholding of consent or making of a request, have any obligation or liability to any other Party (whether such other Party shall also vote or consent or withhold consent or make a request with respect to any Securities, then subject to this Agreement). 4. Certain Remedies. Without intending to limit the remedies available to any of the Parties, each Party agrees that damages at law will be an insufficient remedy in the event such Party violates the terms hereof or the powers granted hereunder and each of the Parties hereto further agrees that each of the other Parties hereto may apply for and have injunctive or other equitable relief in any court of competent jurisdiction to restrain the breach or threatened breach of, or otherwise specifically to enforce, any of such Party's agreements or the powers granted hereunder set forth herein. 5. Representations. Each Party represents and warrants to each other Party that this Agreement is its legal, valid and binding obligation, enforceable against such Party in accordance with its terms, and will not result in any (a) violation or breach of, or be in conflict with, each Party's respective organizational documents or material contracts, or (b) violation of any statutes, laws, rules, regulations, orders or judgments applicable to such Party. J-3

6. Transfer of Securities. Except as otherwise set forth in the Transaction Documents (as defined in the Purchase Agreement), nothing shall prohibit or in any manner restrict any Party's ability to freely transfer, assign, convey, or otherwise dispose of or convert its Securities; provided, that upon the transfer, assignment, conveyance or disposition of any Securities by a Party, such transferring Party shall cause the transferee to which the Securities are transferred, assigned, conveyed or otherwise disposed to agree to be bound by the terms hereof (unless such transfer is made pursuant to an effective registration agreement under the Securities Act or through a broker pursuant to Rule 144). 7. Term. Except as provided in Sections 2(f) and 6 hereof, this Agreement and the Parties' obligations hereunder shall continue in effect for so long as any of Care Capital, Essex or Galen owns the Minimum Threshold. 8. Amendment. Any term of this Agreement or the powers granted hereunder may be amended and the observance of any such term or power may be waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of a majority of the Securities then subject to this Agreement, which majority must include each of Care Capital, Essex and Galen so long as it owns the Minimum Threshold. 9. Binding Effect. (a) This Agreement and the powers granted hereunder shall be binding upon, and shall inure to the benefit of, Care Capital, Essex and Galen and the Parties. (b) Nothing in this Agreement or the powers granted hereunder shall obligate any Party hereto, in his or her capacity as an employee, officer or director of the Company or any of its subsidiaries, to take or refrain from taking any action in any such capacity or shall otherwise affect the rights or obligations of any such party in any such capacity. 10. Notices. All notices, demands or other communications given hereunder shall be in writing and shall be sufficiently given if transmitted by facsimile or delivered either personally or by a nationally recognized courier service marked for next business day delivery or sent in a sealed envelope by first class mail, postage prepaid and either registered or certified, return receipt requested, to the address for each Party as provided on the signature pages hereto, or to such other address as any such Party shall designate in writing. Any such notice, demand or communication shall be deemed to have been given (a) on the date of delivery, if delivered personally, (b) on the date of facsimile transmission, receipt confirmed, (c) one business day after delivery to a nationally recognized overnight courier service, if marked for next day delivery or (d) five business days after the date of mailing, if mailed. 11. Miscellaneous. The section headings herein are inserted for convenience of reference only and shall not affect the meaning or interpretation hereof. This Agreement and the powers granted hereunder contain the entire agreement among the Parties hereto with respect to the matters contemplated herein. If for any reason any provision hereof shall be invalid, unenforceable or inoperative, the validity and effect of the other provisions hereof shall not be affected herein. This Agreement may be executed in one or more counterparts, and by the Parties hereto in separate counterparts, each of which, when so executed and delivered, shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. This Agreement shall become effective as to each signatory hereto upon the execution and delivery hereof by such signatory. This Agreement and the powers granted hereunder shall be governed in all respects by the laws of the State of New York wherein the terms of this Agreement were negotiated, excluding to the greatest extent permitted by law any rule of law that would cause the application of the laws of any jurisdiction other than the State of New York. 12. Board Observers. So long as Galen has the right to designate a director pursuant to Section 2(a) hereof, the Company will permit one observer selected by Galen to attend all meetings of the Board of Directors of the Company, and shall provide such observer with such notice and other information with respect to such meetings as are delivered to the directors of the Company; provided, that such observer shall not be permitted to attend any meeting or portion thereof or have access to such other information if, in the judgment of the Company under advice of counsel, such observer's presence or receipt of such information would adversely affect attorney-client privilege with respect to such meeting or information. J-4

13. Termination of Original Agreement. The Parties acknowledge and agree that this Agreement is entered into in replacement of that certain Voting Agreement dated December 20, 2002 between the Company and the other Parties that are party thereto (the "Original Agreement"), and that upon effectiveness of this Agreement, the Original Agreement shall be terminated and no further legal force or effect.

APPENDIX K VOTING AGREEMENT This VOTING AGREEMENT (this "Agreement") is dated March 19, 2004, and is among HALSEY DRUG CO., INC., a New York corporation (the "Company"), IVAX PHARMACEUTICALS NEW YORK LLC, a New York limited liability company (the "Purchaser"), and each signatory listed on Exhibit A attached hereto (each such signatory a "Holder" and, collectively, the "Holders"). WHEREAS, the Company and the Purchaser are parties to that certain Asset Purchase Agreement dated as of March 19, 2004 (the "Asset Purchase Agreement"), substantially in the form attached hereto as Exhibit B and as finally entered into by the Purchaser pursuant to which the Purchaser is purchasing certain of the Company's assets used in connection with the Company's operations located in Congers, New York, on such terms and conditions as determined by the Company's Board of Directors and the Purchaser (the "Proposed Transaction"); and WHEREAS, to induce the Purchaser to enter into the Asset Purchase Agreement which it would not do but for the agreement of the Holders to enter into this Agreement; and WHEREAS, the closing of the Proposed Transaction is conditioned upon security holders of the Company, who, collectively, represent no less than two-thirds of the Company's issued and outstanding common stock or right to vote as if they owned such common stock, entering into this Agreement. NOW, THEREFORE, the parties agree as follows: 1. Representations and Warranties. Each Holder hereby represents, warrants and covenants to the Purchaser as follows: (a) Title. As of the date hereof, each Holder is the sole beneficial owner of record of the number of shares of each class of security of the Company set forth on Exhibit A hereto (the "Shares"). The term "beneficial owner" and all correlate expressions are used in this Agreement as defined in Rules 13d-3 and 16a-1 under the Securities Exchange Act of 1934, as amended; provided, however, that for the avoidance of doubt, each Holder will not be deemed the beneficial owner of any shares of capital stock of the Company that a Holder has the right to acquire, such as shares issuable to a Holder upon the exercise of an option or warrant, unless and until such shares are actually acquired by a Holder at which time such shares shall be treated as Additional Shares pursuant to Section 5 below; and further provided that notwithstanding the proviso stated above, certain of the Holders have the right to vote their Shares. (b) Right to Vote. As of the date hereof, except for this Agreement or as otherwise permitted by this Agreement, each Holder has full legal power, authority and right to vote all of the Shares then owned of record or beneficially by it, in favor of the approval and authorization of the Proposed Transaction without the consent or approval of, or any other action on the part of, any other Person. Without limiting the generality of the foregoing, each Holder has not entered into any voting agreement (other than this Agreement) with any Person with respect to any of the Shares, granted any Person any proxy (revocable or irrevocable) or power of attorney with respect to any of the Shares, deposited any of the Shares in a voting trust or entered into any arrangement or agreement with any Person limiting or affecting such Holder's legal power, authority or right to vote the Shares on any matter, except for the Voting Agreement dated February 6, 2004, concerning the election of directors and the amendment to the certificate of incorporation to increase the authorized common stock of the Company and authorize the creation of preferred stock. From and after the date hereof, except as otherwise permitted by this Agreement, each Holder will not commit any act that could restrict or otherwise affect such Holder's legal power, authority and right to vote all of the Shares then owned of record or beneficially by such Holder. Without limiting the generality of the foregoing, except for this Agreement and as otherwise permitted by this Agreement, from and after the date hereof, each Holder shall not enter into any voting agreement with any Person with respect to any of the Shares, grant any Person any proxy (revocable or irrevocable) or power of attorney with respect to any of the Shares, deposit any of the Shares in a voting K-1

trust or otherwise enter into any agreement or arrangement of any kind with any Person limiting or affecting such Holder's legal power, authority or right to vote the Shares in favor of the approval of the Proposed Transaction. (c) Authority. Each Holder has full legal power, authority and right to execute and deliver and to perform its obligations under this Agreement. This Agreement has been duly and validly executed and delivered by each Holder and constitutes a legal, valid and binding agreement of each Holder enforceable against it in accordance with its terms. (d) Conflicting Instruments. The execution and delivery of this Agreement and the performance by each Holder of its obligations hereunder will not result in any: (i) violation or breach of, or be in conflict with, such Holder's respective organizational documents or material contracts, as applicable or (ii) violation of any statutes, laws, rules, regulations, orders or judgments applicable to such Holder, as applicable, except for any such breach, violation, conflict or default which, individually or in the aggregate, would not impair or adversely affect such Holder's ability to perform its obligations under this Agreement or render inaccurate any of the representations made by such Holder herein. 2. Covenants. Until the termination of this Agreement in accordance with Section 4, each Holder hereby agrees as follows: (a) Restrictions on Transfer. Each Holder shall not, directly or indirectly, assign, sell, pledge, encumber, transfer (including transfers by testamentary or intestate succession or otherwise by operation of law) or otherwise dispose of (collectively, "Transfer"), or agree to or allow the Transfer, any of the Shares owned of record or beneficially by such Holder or any right, title or interest in any Additional Shares (or any right, title or interest therein, including but not limited to any right or power to vote to which the holder thereof may be entitled, whether such right or power is granted by proxy or otherwise); provided, however, that notwithstanding anything to the contrary contained in this Agreement, a Holder may Transfer Shares or any right, title or interest in any Additional Shares to a transferee if such transferee executes and delivers to the Company and the Purchaser a joinder to this Agreement satisfactory in form and substance to the Company and the Purchaser, stating that such transferee agrees to be fully bound by the terms of this Agreement. (b) Agreement to Vote. Each Holder hereby agrees to vote or to cause to be voted all of the Shares and Additional Shares owned of record or beneficially by such Holder as of the record date for such meeting or written consent, at the Company's upcoming meeting of Shareholders and at any other annual or special meeting of stockholders of the Company where any such proposal is submitted, and in connection with any written consent of stockholders: (A) in favor of the Proposed Transaction; and (B) against any action that may reasonably be expected to (i) impede, interfere with, delay, postpone or attempt to discourage the consummation of the transactions contemplated by the Asset Purchase Agreement or (ii) result in a breach of any of the covenants, representations, warranties or other obligations or agreements of the Company under the Asset Purchase Agreement which would materially and adversely affect the Company or the Purchaser or their respective abilities to consummate the transactions contemplated by the Asset Purchase Agreement. (c) Granting of Proxy. In furtherance of the terms and provisions of this Agreement, and to secure the performance of obligations hereunder, each Holder hereby grants an irrevocable proxy, coupled with an interest, to the Purchaser and any authorized representative or agent of the Purchaser to vote all of the Shares beneficially owned now or during the term of the Asset Purchase Agreement by the Holder in favor of the Proposed Transaction and in accordance with the provisions of Section 2(b) and this Section 2(c). Each Holder hereby ratifies and approves of each and every action taken by the Purchaser and any authorized representative or agent of the Purchaser pursuant to the foregoing proxy. Notwithstanding the foregoing, if requested by the Purchaser, each Holder shall execute and deliver applicable proxy materials in furtherance of the provisions of Section 2(b) and this Section 2(c). (d) Appointing New Agent. Each Holder hereby covenants that if for any reason, Galen Partners III, L.P. is no longer acting as the agent for the Holders, pursuant to a certain Agency Letter Agreement K-2

dated February 6, 2004, the Holders shall appoint a replacement agent and the Holders shall cause such replacement agent to sign an Agent's Release of Liens form in the same form signed by Galen Partners III, L.P. on this date. (e) Each Holder consents to the Company's granting of a first lien and security interest in and to the Purchaser in the Acquired Assets to secure the repayment of the First Closing Payment and no Holder will consent to the granting of any other lien by it or by any Third-Party on the Acquired Assets. 3. Action in Holder Capacity Only. Each Holder makes no agreement or understanding herein as director, officer or employee of the Company. Each Holder signs solely in such Holder's capacity as a record holder and beneficial owner of the Shares, and nothing herein shall limit or affect any actions taken in its capacity as an officer, director or employee of the Company. 4. Amendments; Termination; Modification. (a) Except as otherwise provided herein, this Agreement may not be amended except by an instrument in writing signed on behalf of all parties. (b) This Agreement will terminate upon the earlier to occur of (i) the date and time at which the Company's stockholder approval approving the Proposed Transaction is obtained, and (ii) the termination of the Purchase Agreement in accordance with its terms. 5. Additional Shares. If, after the date hereof, a Holder acquires beneficial or record ownership of any additional shares of capital stock of the Company (any such shares, "Additional Shares"), including, without limitation, upon exercise of any option, warrant or right to acquire shares of capital stock of the Company or through any stock dividend or stock split, the provisions of this Agreement applicable to the Shares will thereafter be applicable to such Additional Shares as if such Additional Shares had been Shares as of the date hereof. The provisions of the immediately preceding sentence will be effective with respect to Additional Shares without action by any person or entity immediately upon the acquisition by such Holder of beneficial ownership of such Additional Shares. 6. Certain Remedies. Without intending to limit the remedies available to any of the parties, each party agrees that damages at law will be an insufficient remedy in the event such party violates the terms hereof or the powers granted hereunder. Each party agrees that each of the other parties hereto may apply for and have injunctive or other equitable relief in any court of competent jurisdiction to restrain the breach or threatened breach of, or otherwise specifically to enforce, any of such party's rights or powers granted hereunder. 7. Binding Effect. This Agreement and the powers granted hereunder will be binding upon, and inure to the benefit of, the parties hereto, their successors and permitted assigns. 8. Notices. All notices, demands or other communications given hereunder must be in writing and transmitted by facsimile or delivered either personally or by a nationally recognized courier service marked for next business day delivery or sent in a sealed envelope by first class mail, postage prepaid and either registered or certified, return receipt requested, to the address for each party as provided on the signature pages hereto, and in the case of the Purchaser with a copy to the General Counsel or to such other address as any such party may designate in writing.
