Page 7 of 16 Item 1. Security and Issuer. This statement on Schedule 13D (this "Schedule 13D") relates to the Common Stock, par value $0.01 per share (the Shares") of Halsey Drug Co., Inc., a New York corporation (the "Company"). The principal executive offices of the Company are located at 695 N. Perryville Road, Crimson Building No. 2, Unit 4, Rockford, Illinois 61107. Item 2. Identity and Background. This Schedule 13D is being filed jointly on behalf of the following persons (the "Filing Persons"): Care Capital Investments II, LP, a Delaware limited partnership ("CC LP"), Care Capital II, LLC, a Delaware limited liability company ("CC LLC"), Jan Leschly, a managing member of CC LLC, David Ramsay, a managing member of CC LLC, and Jerry Karabelas, a managing member of CC LLC. The Joint Filing Agreement among the Filing Persons is annexed hereto as Exhibit 1. The address of the principal business and office of CC LP and CC LLC is 47 Hulfish Street, Suite 310, Princeton, NJ 08542. The principal business of CC LP is to invest in securities. The principal business of CC LLC is to serve as the general partner of CC LP. Attached as Schedule 1, which is incorporated herein by reference, is the name, business address, present principal occupation or employment, name, principal business and address of the organization in which such employment is conducted, and citizenship of each of the managing members of CC LLC. During the five years prior to the date hereof, none of the Filing Persons or, to the best knowledge of the Filing Persons, any managing member of CC LLC has been convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors). During the five years prior to the date hereof, none of the Filing Persons or, to the best knowledge of the Filing Persons, any managing member of CC LLC was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or State securities laws or finding any violation with respect to such laws. Pursuant to certain provisions described more fully in Item 4 below, CC LLC, CC LP, Mr. Leschly, Mr. Ramsay and Mr. Karabelas may be deemed to be members of a group along with the other 2002 Holders, Galen (as defined below), Oracle (as defined below), Michael Reicher, Chief Executive Officer of the Company, and Peter Clemens, Chief Financial Officer of the Company and thus may be deemed to indirectly beneficially own 65,957,490 additional Shares beneficially owned by the other 2002 Holders, Galen, Oracle, Mr. Reicher and Mr. Clemens. Each of CC LLC, CC LP, Mr. Leschly, Mr. Ramsay and Mr. Karabelas disclaims ownership of such additional Shares.

Page 8 of 16 - -------------------------------------------------------------------------------- Item 3. Source and Amount of Funds or Other Consideration. The general and limited partners of CC LP contributed, in the aggregate, $5,000,000 to CC LP to fund CC LP and the acquisition of a 5% convertible senior secured debenture of the Company in the principal amount of $5,000,000. Item 4. Purpose of Transaction. Pursuant to the Debenture Purchase Agreement, dated December 20, 2002, by and among the Company, CC LP and the other parties set forth on Exhibit A attached thereto (the "Debenture Purchase Agreement"), annexed hereto as Exhibit 2 and described more fully below, the Company completed a private sale of its 5% convertible senior secured debentures (the "Debentures") to CC LP and certain other purchasers (collectively, together with CC LP, the "2002 Holders"). Pursuant to the terms and conditions of the Debenture Purchase Agreement, CC LP acquired a Debenture in the principal amount of $5,000,000 (the "CC LP Debenture") for a purchase price of $5,000,000. The CC LP Debenture is convertible into Shares at any time at the option of the holder. The current conversion price of the Debentures is $0.34 per share. Thus, CC LP may currently be deemed to beneficially own 14,705,882 Shares. The CC LP Debenture and the Shares underlying the CC LP Debenture that may be acquired by CC LP upon conversion thereof and which CC LP may be deemed to beneficially own were acquired for, and are being held for, investment purposes, and were acquired in the ordinary course of business and not for the purpose of acquiring control of the Company. A. Debenture Purchase Agreement i. Preemptive Rights The Debenture Purchase Agreement provides that if the Company desires to sell any equity securities (including convertible debt securities) to a third party, the Company must first offer to sell such securities to the 2002 Holders on a pro rata basis on the terms and conditions specified by the Company (the "Offer"). The Offer must remain open for at least 30 days, and is subject to certain limitations and exceptions, as more fully described in the Debenture Purchase Agreement. ii. Co-Sale Rights The Debenture Purchase Agreement provides that if Galen Partners, L.P., Galen Partners International III, L.P., Galen Employee Fund III, L.P. (collectively, "Galen"), Oracle Strategic Partners L.P. ("Oracle"), Michael Reicher, Chief Executive Officer of the Company, or Peter Clemens, Chief Financial Officer of the Company, intends to transfer any Shares owned by it/him or any Debentures or certain other debt securities owned by it/him, such transferor (the "Selling Security Holder") must notify the 2002 Holders in writing of such proposed transfer and the terms and conditions thereof. Within 15 business days of the date of such notice, each 2002 Holder must notify the Selling Security Holder if such holder elects to participate in the proposed transfer described in the written notice provided by the Selling Security Holder. Any 2002 Holder that desires to participate in such transfer may do so on a pro rata basis, subject to certain terms and conditions, as more fully described in the Debenture Purchase Agreement.

                               DUE MARCH 31, 2006


                              HALSEY DRUG CO., INC.

                          DEBENTURE PURCHASE AGREEMENT

                          DATED AS OF DECEMBER 20, 2002




To the Purchaser(s) Set Forth on Exhibit A hereto: HALSEY DRUG CO., INC., a New York corporation (the "Company"), agrees with you as follows (capitalized terms used in this Agreement without definition have the meanings assigned to them in Article XX): ARTICLE I AUTHORIZATION OF THE SECURITIES; ADJUSTMENT OF CONVERSION PRICE 1.1. Authorization of Securities. (a) The Company represents that it has taken all corporate action necessary to authorize the issuance and sale of its 5% Convertible Senior Secured Debentures due March 31, 2006 in the aggregate principal amount of up to $35 million substantially in the form of Exhibit B hereto (such Debentures, together with the Debenture instruments evidencing interest payments on the Debentures in accordance with Section 1.1, as they may be amended, supplemented or otherwise modified from time to time in accordance with their terms, the "Debentures" or the "Securities"). (b) The Debentures are to be sold severally, and not jointly, pursuant to this Agreement to you (each of you is sometimes referred to herein as a "Purchaser"). (c) Interest on the Debentures (including on Debenture instruments issued pursuant to this sentence) is payable at the rate of 5% per annum in the form of Debenture instruments substantially identical to the Debentures; provided, however, that fifty percent (50%) of the interest payments payable under the Debentures issued to Care Capital Investments II, LP shall be paid in cash with the balance of such interest payments payable in like Debentures, all as more particularly specified in the Debenture. Each Debenture held by Galen, Galen Partners International III, L.P., Galen Employee Fund III, L.P. and any Additional Investor, or any affiliate thereof is convertible, at any time after the Shareholders Meeting Date, (i) in whole or in part at any time or from time to time at the option of the holder of such Debenture into a number of shares of the Company's Common Stock (the "Common Stock") initially at the rate of one share of Common Stock for each $0.34 in principal amount of the respective Debenture to be converted and (ii) following the third anniversary of the issuance of the respective Debenture, in whole at the option of the Company in the circumstances set forth in Section 3.2 of the respective Debenture. Each Debenture held by Care Capital Investments II, LP or Essex Woodlands Health Ventures Fund V is convertible (i) in whole or in part at any time or from time to time at the option of the holder of such Debenture into a number of shares of Common Stock initially at the rate of one share of Common Stock for each $0.34 in principal amount of the respective Debenture to be converted and (ii) following the third anniversary of the issuance of the respective Debenture, in whole at the option of the Company in the circumstances set forth in Section 3.2 of the respective Debenture. For purposes of this Agreement, the term "Shares" shall mean the shares of Common Stock which may be issued upon conversion of all or a portion of the principal amount of the Debentures. The term Shares does not include any other shares of Common Stock or other capital stock of the Company. (d) The Company and the Purchasers acknowledge and agree that the conversion price of the Debentures shall be calculated on the Closing Date and on any subsequent issuance of Debentures pursuant to Article III hereof (i) based on a fully-diluted valuation of the Company of $47.4 million prior to the Closing of the transactions provided in this Debenture Purchase Agreement, assuming a per share value of Common Stock equal to the conversion price of the Debentures, and (ii) to provide that the Debentures issued to the Purchasers shall be convertible into such number of Shares as shall represent forty two and four tenths percent (42.4%) (the "Aggregate Ownership Percentage") of the Company's Common Stock on the Closing Date, assuming the Company's issuance of Debentures in an aggregate principal amount of $35 million. The Aggregate Ownership Percentage shall be proportionately adjusted to the extent the Company issues Debentures in an aggregate principal amount less than $35 million. For purposes of the foregoing calculations, excluding common stock purchase options exercisable for up to 5,031,950 shares of Common Stock issued and outstanding on the Closing Date and listed on Section 1.1 of the Schedule of Exceptions, all shares of Common Stock underlying any convertible debentures, warrants, options and other convertible securities of the Company outstanding at the Closing Date shall be included, including, without limitation, the Watson Warrant, after giving effect to any change in the number of shares of Common Stock issuable under such convertible securities as a result of the completion of the transactions set forth in this Debenture Purchase Agreement and the application of the anti-dilution provisions contained in any such convertible securities. 1.2. Adjustment of Conversion Price. (a) The prices at which Shares may be acquired upon conversion of the Debentures are subject to adjustment as set forth in the Debentures. Without limiting the anti-dilution provisions contained in the Debentures, including, without limitation, Section 3.7 thereof, the Purchasers and the Company acknowledge and agree that in the event the common stock purchase warrants described in Exhibit O hereto exercisable for an aggregate of 11,475,116 shares of Common Stock (collectively, the "Remaining Galen Warrants") are exercised, converted, recapitalized or otherwise exchanged or substituted (the "Warrant Exchange Transaction") on or before December 15, 2003 for an aggregate number of shares which is less than or greater than 11,475,116 shares of Common Stock, the conversion price of the Debentures shall be adjusted in order to provide that the number of Shares issuable upon conversion of the Debentures shall equal the Aggregate Ownership Percentage as if the Warrant Exchange Transaction had been completed immediately prior to the Closing Date and the Company had issued the resulting shares of Common Stock in such transaction as of the Closing Date. (b) In accordance with Article III hereof, the Company, from time to time, may issue additional Debentures pursuant to this Agreement; provided, however, that (i) the aggregate principal amount of the Debentures shall not exceed $35 million, and (ii) that no Debentures (other than the Debenture instruments evidencing interest payments on the Debentures in accordance with Section 1.1) shall be issued after August 30, 2003 (the "Termination Date"). Upon the execution of the Joinder Agreement appended as Exhibit J hereto by a Purchaser and the Company's issuance of a Debenture to such Purchaser, the conversion price of the Debentures issued on the Closing Date and the conversion price of any Debenture issued at any time after the Closing Date as provided in this Section 1.2 (b) and Article III hereof, shall be adjusted to give effect to the requirements of Section 1.1(d) hereof, including, without limitation, after giving effect to any change in the number of shares of Common Stock issuable under the Company's outstanding convertible securities (exclusive of the Debentures) as a result of the Company's issuance of additional Debentures following the Closing Date and the application of the anti-dilution provisions contained in the Company's convertible securities. ARTICLE II SALE AND PURCHASE OF THE SECURITIES; SECURITY DOCUMENTS 2.1. Sale and Purchase of the Securities. At the Closing, on the terms and subject to the conditions and in reliance on the representations and warranties contained herein, or made pursuant hereto, the Company shall issue, sell and deliver to each Purchaser and such Purchaser's designees, and each Purchaser, severally and not jointly, will purchase from the Company, the Debentures for the purchase prices set forth opposite such Purchaser's name on Exhibit A. 2.2.

(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 at least a 66 2/3% in aggregate principal amount of the Debentures then outstanding, 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 a 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 then outstanding, describing such notice or other action and the nature of the claimed default. (c) Notwithstanding anything to the contrary contained in Section 12.2(a), upon the occurrence of an Event of Default specified in Section 12.1(b), the Company and the Purchasers agree that a Holder will suffer damages and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company agrees to pay liquidated damages ("Liquidated Damages") to each applicable Holder for any such continuing Event of Default, as follows: Liquidated Damages shall accrue on the principal amount of the Securities at a rate of $2.00 per calendar day per $1,000 principal amount of Debentures for the first 90 days immediately following each such Event of Default, and such Liquidated Damages shall increase by an additional $2.00 per calendar day per $1,000 principal amount of Debentures at the beginning of each subsequent 90-day period. As provided in Section 19.6 hereof, the remedy of Liquidated Damages shall be cumulative, and shall not exclude the availability of any other remedies hereunder or under the Transaction Documents (including, without limitation, the payment of late charges and default interest as provided in the Debentures). 12.3. Enforcement. In case any one or more Events of Default shall occur and be continuing, the holder of a Debenture then outstanding 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 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 any Debenture 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. To the greatest extent permitted by applicable law, the Company agrees to indemnify each Purchaser against and hold it harmless from all claims, losses, damages, liabilities (or actions in respect thereof), obligations, penalties, awards, judgments, expenses (including, without limitation, reasonable fees and expenses of counsel) or disbursements (each a "Loss") 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) Care Capital Investments II, LP 's and Essex Woodlands Health Ventures' representation on the Company's Board of Directors and any committees thereof or as an observer thereon. 13.2. 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 herein, 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 19.2. 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 19.2. 13.3. Such 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 hereunder. 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. ARTICLE XIV AMENDMENT AND WAIVER 14.1. 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 (a) the Company, and each of Galen, Care Capital Investments II, LP or Essex Woodlands Health Ventures Fund V, so long as they (or their affiliates (as such term is defined in Rule 501(b)) shall hold Debentures, and (b) the holders of at least 51 % in the aggregate principal amount of the Debentures then outstanding, and 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.

Promptly after obtaining the written consent of the holders of 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.

Intentionally Omitted. ARTICLE XVI TRANSFER OF DEBENTURES 16.1. Notification of Proposed Sale. (a) Subject to Section 16.1(b), each holder of a Debenture by acceptance thereof agrees that it will give the Company ten days written notice prior to selling or otherwise disposing of such Debenture.

16.2. Intentionally Omitted. ARTICLE XVII RIGHT OF FIRST REFUSAL; ADDITIONAL INVESTMENT 17.1. Right of First Refusal. Each holder of the Debentures, holder of Shares (provided any Debentures remain outstanding and the Shares received upon conversion have not been sold, transferred or otherwise disposed of) (the "Common Holder"), holders of the March 1998 Debentures (the "Existing 1998 Debentureholders") and holders of shares of Common Stock issued upon the conversion of the March 1998 Debentures (provided any March 1998 Debentures remain outstanding and the shares of Common Stock received upon conversion have not been sold, transferred or otherwise disposed of) (the "Old Common Holders") 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 (except as provided in Section 6.16), sale or exchange (i) any shares of Common Stock, (ii) any other equity security of the Company, (iii) any debt security of the Company which by its terms is convertible into or exchangeable for, with or without consideration, any equity security of the Company, (iv) any security of the Company that is a combination of debt and equity or (v) any option, warrant or other right to subscribe for, purchase or otherwise acquire any equity security or any such debt security of the Company (collectively, the "Equity Securities") unless in each case, the Company shall have first offered to sell to the holders of Debentures, the Common Holders, the Existing 1998 Debentureholders and the Old Common 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 holders of Debentures, the Common Holders, the Existing 1998 Debentureholders and the Old Common 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 holders of Debentures, the Common Holders, the Existing 1998 Debentureholders and the Old Common 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 holders of Debentures, the Common Holders, the Existing 1998 Debentureholders and the Old Common 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 holder of Debentures, Common Holder, Existing 1998 Debentureholders and the Old Common Holders shall be that amount of the Equity Securities multiplied by a fraction, the numerator of which is the sum of (i) Shares underlying the Debenture held by such Person if such Person is the holder of a Debenture, (ii) the number of Shares of Common Stock issued to such Common Holder upon conversion of a Debenture if such Person is a Common Holder, (iii) the number of shares of Common Stock underlying the March 1998 Debentures held by such Person if such Person is an Existing 1998 Debentureholder and (iv) the number of shares of Common Stock issued to an Existing 1998 Debentureholder upon conversion of a March 1998 Debenture if such Person is an Old Common Holder, and the denominator of which is the sum of (x) the total number of shares of Common Stock underlying the Debentures issued pursuant to this Agreement and (y) the total number of shares of Common Stock underlying the March 1998 Debentures. (c) Notice of the intention of each holder of a Debenture, Common Holder, Existing 1998 Debentureholder or Old Common 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 holders of Debentures, Common Holders, Existing 1998 Debentureholders and Old Common 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 subparagraph (c) above 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 subparagraph (c) above. Following such additional ten-day period, in the event the holders of the Debentures, the Common Holders, Existing 1998 Debentureholders and the Old Common 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 holders of Debentures, the Common Holders, Existing 1998 Debentureholders and Old Common Holders have timely submitted a Notice of Acceptance, it and they shall purchase from the Company, and the Company shall sell to such persons, as the 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 holders of Debentures, Common Holders, Existing 1998 Debentureholders and the Old Common 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 holders of Debentures, the Common Holders, Existing 1998 Debentureholders and the Old Common Holders or by a Person or Persons in accordance with Section 17.1(d) hereof 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), (c) and (d) hereof. (f) The rights of the holders of Debentures, the Common Holders, Existing 1998 Debentureholders and the Old Common 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 of the Company; (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 or exercise of the warrants issued in connection with the issuance of the Existing Debentures; (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 Shareholders; 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 or a Common Holder (other than an initial Purchaser) shall not be considered as such for purposes of this Section 17.1 only, unless such Person then holds Debentures with an outstanding principal amount of at least $200,000 or Shares issued upon conversion of at least $200,000 in principal of Debentures or a combination of Debentures and Shares such that the outstanding principal of the Debentures held by such Person plus the amount of principal of Debentures converted into Shares held by such Person equals or exceeds $200,000. ARTICLE XVIII CO-SALE RIGHTS 18.1. In the event that Galen Partners, L.P., Galen Partners International III, L.P., Galen Employee Fund III, L.P., Oracle Strategic Partners L.P., Michael Reicher, Chief Executive Officer of the Company or Peter Clemens, Chief Financial Officer of the Company intends to transfer, directly or indirectly, in one or in a series of related transactions, any shares of the Company's Common Stock owned by it/him or any principal amount of the Existing Debentures or Debentures owned by it/him, such transferor (the "Selling Security Holder") shall notify the Holders in writing of such proposed transfer and its terms and conditions and within 15 business days of the date of such notice, each Holder shall notify the Selling Security Holder if such Holder elects to participate in the proposed transfer described in the written notice provided by the Selling Security Holder (a "Transfer"). Any Purchaser that fails to notify the Selling Security Holder within such 15 business day period shall be deemed to have waived its rights hereunder with respect to the Transfer described in the Selling Security Holder's written notice. Each Holder that notifies the Selling Security Holder that it intends to participate in the proposed Transfer, shall have the right to sell at the same price and on the same terms and conditions as the Selling Security Holder (a) in the case of a sale of shares of the Company's Common Stock by the Selling Security Holder, a number of shares of Common Stock equal to the shares of Common Stock proposed to be sold in the Transfer multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock owned by the Holder (inclusive of all shares underlying the Debentures) and the denominator of which shall be the sum of (i) the Company's outstanding shares of Common Stock, plus (ii) the shares underlying the Debentures and the Existing Debentures, and (b) in the case of the proposed sale of Existing Debentures or Debentures by such Selling Security Holder, the principal amount of the Existing Debentures or Debentures proposed to be sold in the Transfer multiplied by a fraction, the numerator of which shall be the aggregate principal amount of the Debentures owned by the Holder and the denominator of which shall be the aggregate principal amount of the Company's outstanding Existing Debentures and Debentures. Nothing in this Article XVIII shall be construed to limit the ability of the Selling Security Holder to complete the Transfer prior to the passage of ten business days notice period provided above, provided that sufficient accommodation is made to permit the Holders to complete the sale of their Common Stock and Debentures hereunder within ten business days of the election by such Holders to exercise their co-sale rights hereunder. The exercise or non-exercise of the rights of any Holder with respect to any particular Transfer shall not waive any such Holder's rights to participate in a subsequent Transfer. 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. 19.2.

No delay or omission to exercise any right, power or remedy accruing to any holder of any Securities 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; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any holder of any breach or default under this Agreement, or any waiver on the part of any holder of any provisions or conditions of this Agreement must be, made in writing and shall be effective only to the extent specifically set forth in such writing.

Independence of Covenants and Representations and Warranties.

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. 19.8. 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.

                                VOTING AGREEMENT

     This VOTING  AGREEMENT  (this  "Agreement")  dated as of December 20, 2002,
among the Parties signatory hereto (the "Parties").

     WHEREAS, Halsey Drug Co., Inc., a New York corporation (the "Company"), has
entered into the Debenture  Purchase  Agreement dated of even date herewith (the
"Purchase Agreement"), by and among the Company, Care Capital Investments II, LP
("Care   Capital"),   Essex  Woodlands  Health  Ventures   ("Essex")  and  other
signatories thereto, providing for the issuance by the Company of 5% Convertible
Senior  Secured  Debentures  due March 31, 2006 (the "2002  Debentures")  in the
aggregate principal amount of $35,000,000; and

     WHEREAS,  Care Capital and Essex will purchase  $5,000,000 and  $5,000,000,
respectively,  in principal amount of the 2002 Debentures  pursuant to the terms
of the Purchase Agreement; and

     WHEREAS,  the Company does not have enough authorized and unreserved shares
of its Common Stock, $.01 par value per share (the "Common Stock") available for
issuance upon the conversion of the 2002 Debentures; and

     WHEREAS,  the Purchase  Agreement  contemplates  that the purchasers of the
2002 Debentures  shall have the right to vote as part of a single class with all
holders  of the  Company's  common  stock on an  as-converted  basis;  provided,
however, that for so long as Care Capital holds any 2002 Debentures, such voting
rights shall not apply to Care Capital; and

     WHEREAS,  the Company desires to amend its Certificate of  Incorporation to
provide for (a) an increase in the number of shares of its Common Stock in order
to reserve a sufficient number of shares for issuance upon the conversion of the
Debenture;  and (b) the  as-converted  voting  rights to the holders of the 2002

recital); and

     WHEREAS, as additional consideration for the investment by Care Capital and
Essex,  the Purchase  Agreement  provides that so long as Care Capital and Essex
remain a  holder  of the 2002  Debentures,  the  Parties  desire  to vote  their
Securities  (as  defined  below) in such a manner so as to elect a Care  Capital
nominee and an Essex nominee to the Board of Directors of the Company.

     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  Annual 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  (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 (the "1999  Debentures",  and together with the 1998
Debentures,  the  "Existing  Debentures")  (collectively  with the shares of the
Company's Common Stock, issuable upon conversion of the Existing Debentures, the
"Securities")  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 such number as shall equal the sum of
(i) the Company's issued and outstanding  Common Stock,  plus (ii) the number of
shares  of  Common  Stock  issuable  upon the  conversion  and  exercise  of the
Company's outstanding convertible securities, plus (iii) the number of shares of
Common Stock issuable upon conversion of the 2002 Debentures and the exercise of
the Watson  Warrant (as such term is defined in the  Purchase  Agreement),  plus
(iv) 50 million  shares,  as such sum shall be rounded up to the  nearest  whole
five million shares; and

     (b) Providing that the holders of the 2002 Debentures  shall have the right
to vote as part of a single  class with all  holders of the Common  Stock of the
Company on all  matters  to be voted on by such  stockholders  with each  holder
having  such  number of votes as shall equal the number of votes they would have
had such holders converted the entire  outstanding  principal amount of the 2002
Debentures immediately prior to the record date relating to such vote.

     2.  Election  of Care  Capital  Nominee  and Essex  Nominee.  From the date
hereof,  each Party and Care  Capital and Essex (each of Care Capital and Essex,
and their  permitted  transferees  and  assigns,  being  referred to herein as a
"Designating Party") agree as follows:

     (a) Each Party holding  Securities  shall vote its Securities,  and take or
cause to be taken such other  actions,  as may be required  from time to time to
elect to the Board of  Directors  of the Company one person  designated  by each
Designating  Party.  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 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 when such removal is requested for
any reason, with or without cause, by such Designating Party. In the case of the
death,  resignation  or  removal as herein  provided  of a  Designating  Party's
designee,  each Party  shall  vote all  Securities  held by it to elect  another
person designated by such Designating Party pursuant to Section 2(a);

     (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,  unless  the  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 a proxy to
vote its Securities  solely for the election of the nominee of such  Designating
Party or the removal of such 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  shall  be, if so
requested by such  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,  with the rights of a Designating  Party
terminating on the date such Designating Party ceases to be a holder of the 2002
Debentures.

     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.

     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, however, that upon the
transfer,  assignment,  conveyance or  disposition of any Securities by a Party,
such  transferring  Party  shall  cause the Person to which the  Securities  are
transferred,  assigned,  conveyed or otherwise  disposed to agree to be bound by
the terms hereof.

     7. Term.  This  Agreement  and the  Parties'  obligations  hereunder  shall
continue  in  effect  for so  long as Care  Capital  and  Essex  owns  any  2002
Debentures.

     8.  Amendment.  (a) 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 Care Capital and Essex and the
holders of a majority of the Securities then subject to this Agreement.

     (b) This Agreement and the powers granted  hereunder may be terminated only
with the written consent of Care Capital, Essex and all Parties hereto.

     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 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.

                                   ARTICLE I

              PAYMENT OF PRINCIPAL AND INTEREST; METHOD OF PAYMENT

     1.1.  Payment of the principal on this Debenture shall be made 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) on the unpaid  portion of
said principal amount from time to time outstanding shall be paid by the Company
at the rate of five percent (5%) per annum (the "Stated Interest Rate"), payable
to the Payee in  three-month  intervals  on each  January 1, April 1, July 1 and
October 1 during  the term of this  Debenture  (commencing  January 1, 2003) (an
"Interest  Payment  Date")  and on the  Maturity  Date.  The  payment of accrued
interest on this Debenture  shall be made (i) in cash, in immediately  available
funds,  such coin or currency  of the United  State of America as at the time of
payment  shall be legal tender for the payment of public and private  debts,  in
the amount of fifty  percent  (50%) of each such accrued  interest  payment (the
"Cash Interest Portion");  and (ii) in the form of 5% convertible senior secured
debentures (each, an "Interest Payment Debenture")  identical in all respects to
this  Debenture,  in the  amount of fifty  percent  (50%) of each  such  accrued
interest  payment;  provided,  however,  that (i) the  principal  amount of such
Interest  Payment  Debenture  upon  issuance  shall be the  accrued  and  unpaid
interest for the immediately  preceding calendar quarter,  (ii) the date of such
Interest  Payment  Debenture  shall be its issue date,  and (iii) the Conversion
Price (as defined in Section 3.1(a)  hereof) of such  debenture  shall equal the
average of the closing bid and asked  prices for the  Company's  Common Stock as
reported in the  Over-the-Counter  Bulletin Board ("OTC Bulletin Board")(or such
other  over-the-counter  market or exchange on which the Company's  Common Stock
may then be traded or admitted for trading) for the 20 trading days  immediately
preceding the date of such interest  payment.  No cash interest payments will be
made on this Debenture except (i) for the Cash Interest Portion, and (ii) on the
Maturity  Date  pursuant  to the terms of the  Interest  Rate  Debentures.  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 (to the extent  payable in cash)  interest
by check or wire transfer, at the Holder's election,  and (to the extent payable
by the  issuance  of  Interest  Payment  Debentures)  interest in the form of an
Interest Payment Debenture,  sent to the Holder's above address or to such other
address  as the  Holder  may  designate  for such  purpose  from time to time by
written notice to the Company,  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.


     1.2.  In the event any  payment  of  principal  or,  (except  to the extent
otherwise specified herein) interest or both shall remain unpaid for a period of
two business days or more, a late charge equivalent to five (5%) percent of each
installment  shall be charged and may be  satisfied by the payment of cash (with
respect to fifty percent (50%) of such amount) and the Company's  issuance of an
Interest  Payment  Debenture  (with respect to the remainder  thereof)  having a
principal  amount which includes such late charge.  Interest on the indebtedness
evidenced by this Debenture after default or maturity  accelerated  shall be due
and  payable  at the  rate of seven  (7%)  percent  per  annum,  subject  to the
limitations of applicable law.


     1.3. If this Debenture or any installment 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 rate of five (5%) percent per annum during
such  extension.  All payments  received by the Holder shall be applied first to
the payment of all accrued interest payable hereunder.

                                   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 dated as of December
20, 2002, and the collateral  assignments referred to in the Purchase Agreement.
In addition,  each of Houba, Inc.  ("Houba") and Halsey  Pharmaceuticals,  Inc.,
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 dated as of December 20, 2002, and the collateral assignments referred
to in the Purchase  Agreement.  The  obligations of Houba under its Guaranty are
also secured (subject to the Subordination  Agreement) pursuant to a mortgage on
real property located at 16235 State Road 17, Culver, Indiana. 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 the Subordination Agreement dated
of even date herewith by and among the Company,  Watson  Pharmaceuticals,  Inc.,
the Holders and the other signatories thereto.

                                  ARTICLE III

                                   CONVERSION

     3.1.  Conversion at Option of Holder.  At any time and from time to time on
and after December 20, 2002 (the "Initial Conversion Date") until the earlier of
(a) the Maturity Date or (b) the conversion of the Debenture in accordance  with
Section 3.2 hereof,  this  Debenture is  convertible  in whole or in part at the
Holder's  option into shares of Common  Stock of the Company  upon  surrender of
this Debenture, at the office of the Company, accompanied by a written notice of
conversion in the form of Attachment II hereto,  or otherwise in form reasonably
satisfactory  to the Company duly executed by the registered  Holder or its duly
authorized  attorney.  This  Debenture  is  convertible  on or after the Initial
Conversion Date into shares of Common Stock at a price per share of Common Stock
equal to $.34 per share, as such conversion price may be adjusted as provided in
Sections 3.5, 3.6 and 3.7 hereof (as so adjusted) (the "Conversion  Price").  No
fractional  shares or scrip  representing  fractional shares will be issued upon
any  conversion,  but an  adjustment  in cash will be made,  in  respect  of any
fraction of a share which would otherwise be issuable upon the surrender of this
Debenture  for  conversion.  The  Conversion  Price is subject to  adjustment as
provided in  Sections  3.5,  3.6 and 3.7  hereof.  Not later than three (3) days
following  conversion  and  upon the  Holder's  compliance  with the  conversion
procedure  described  in  Section  3.3  hereof,  the  Company  shall  deliver  a
certificate  for the  number  of full  shares  of  Common  Stock  issuable  upon
conversion and a check for any fractional  share and, in the event the Debenture
is  converted in part, a new  Debenture  of like tenor in the  principal  amount
equal to the remaining  principal  balance of this Debenture after giving effect
to such partial conversion.

     3.2. Conversion at Option of the Company. So long as an Event of Default as
provided in Section 12.1(a) of the Purchase Agreement  (concerning the Company's
failure to pay  principal  and  interest  under the  Debentures)  shall not have
occurred and be continuing,  in the event that following  December 20, 2005, (i)
the  average of the  closing  bid and asked  prices  per share of the  Company's
Common  Stock as reported by the OTC Bulletin  Board (or such other  exchange or
over-the-counter  market on which the Shares may then be listed or admitted  for
trading)  exceeds the product of (x) the then  Applicable  Conversion  Price (as
defined in Section 3.7 hereof), multiplied by (y) four, (but only if the average
daily trading volume for such 20 trading day period exceeds one million  dollars
($1,000,000)  (based on the number of Shares traded multiplied by the average of
the closing bid and asked prices)),  or (ii) the Company shall have obtained the
written  consent of the Holders of at least 75% of the  principal  amount of the
Debentures then outstanding to convert the Debentures into Common Stock, then at
any time during the 30-day period thereafter the Company may upon written notice
to the Holders of all Debentures (the  "Mandatory  Conversion  Notice")  require
that all,  but not less than all,  of the  outstanding  principal  amount of the
Debentures  be converted  into shares of Common Stock at a price per share equal
to the Conversion Price then in effect.  The Mandatory  Conversion  Notice shall
state (a) the date fixed for  conversion  (the  "Conversion  Date")  (which date
shall not be prior to the date the Mandatory  Conversion  Notice is given),  (b)
any disclosures required by law, (c) the trading dates and closing prices of the
Common Stock giving rise to the  Company's  option to require  conversion of the
Debenture,  (d) that the Debentures shall cease to accrue interest after the day
immediately  preceding the  Conversion  Date, (e) the place where the Debentures
shall be delivered  and (f) any other  instructions  that Holders must follow in
order to tender their  Debentures in exchange for certificates for Common Stock.
No failure to mail such notice nor any defect therein or in the mailing  thereof
shall affect the validity of the proceedings for such conversion, except as to a
Holder (i) to whom notice was not mailed or (ii) whose notice was defective.  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 two sentences,  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 Common Stock as to which
the Debenture shall have been converted.  Interest shall accrue to and including
the day  prior to the  Conversion  Date and shall be paid on the last day of the
month  in  which  Conversion  Date  occurs.   No  fractional   shares  or  scrip
representing  fractional  shares  will be  issued  upon any  conversion,  but an
adjustment  in cash will be made,  in respect of any  fraction  of a share which
would otherwise be issuable upon the surrender of this Debenture for conversion.

     3.3.  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.  The Company  shall  convert,  from time to
time, any outstanding  Debentures upon the books to be maintained by the Company
for such purpose upon surrender thereof for conversion properly endorsed and, in
the case of a  conversion  pursuant  to Section  3.1  hereof,  accompanied  by a
properly completed and executed  Conversion Notice attached hereto as Attachment
II. Subject to the terms of this Debenture,  not later than three 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 Common 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  date of the  surrender  of this
Debenture.

     3.4.  Company to  Provide  Common  Stock.  The  Company  has  reserved  the
remaining balance of its authorized but unissued and unreserved shares of Common
Stock to permit the  conversion  of the  Debentures to the extent of its current
unissued  and  unreserved  authorized  Common  Stock.  In  accordance  with  the
provisions of Section 9.12 of the Purchase  Agreement,  the Company covenants to
seek the approval of its  shareholders and directors to amend its Certificate of
Incorporation  (i) to increase its  authorized  shares from  80,000,000  to such
number  of  shares  as  shall  equal  the sum of (A) the  Company's  issued  and
outstanding Common Stock, plus (B) the number of shares of Common Stock issuable
upon the  conversion  and  exercise  of the  Company's  outstanding  convertible
securities,  plus (C) the  number  of  shares  of  Common  Stock  issuable  upon
conversion  of the  Debentures  and  exercise  of the Watson  Warrant,  plus (D)
50,000,000  shares,  as such sum shall be rounded up to the  nearest  whole five
million  shares,  and (ii) to provide voting rights to certain  Holders on an as
converted basis as a single class with the holders of the Common Stock. Promptly
upon receipt of shareholder  approval to amend its certificate of  incorporation
to  increase  its  authorized  shares,  the  Company  shall  reserve  out of its
authorized but unissued shares of Common Stock a sufficient  number of shares to
permit the  conversion  of the  Debentures  in full.  The shares of Common Stock
which may be issued upon the  conversion of the  Debentures  shall be fully paid
and  non-assessable  and free of preemptive rights. The Company will comply with
all  securities  laws  regulating  the offer and  delivery  of the  Shares  upon
conversion  of the  Debentures  and  will  list  such  shares  on each  national
securities  exchange,  if any,  upon which the Common  Stock may then be listed.

     3.5.  Dividends;  Reclassifications,  etc.  In the event  that the  Company
shall,  at any time prior to the earlier to occur of (a) exercise of  conversion
rights hereunder and (b) the Maturity Date: (i) declare or pay to the holders of
the Common  Stock a dividend  payable in any kind of shares of capital  stock of
the  Company  or rights to  acquire  any  thereof;  or (ii)  change or divide or
otherwise  reclassify  its Common  Stock into the same or a different  number of
shares with or without par value, or in shares of any class or classes; or (iii)
transfer  its  property as an entirety  or  substantially  as an entirety to any
other company or entity;  or (iv) make any distribution of its assets to holders
of its Common Stock as a liquidation or partial  liquidation  dividend or by way
of return of capital;  then, upon the subsequent  exercise of conversion rights,
the Holder shall receive,  in addition to the shares of Common Stock to which it
would otherwise be entitled upon such exercise,  such additional shares of stock
or scrip of the Company, or such reclassified shares of stock of the Company, or
such  shares  of the  securities  or  property  of the  Company  resulting  from
transfer,  or such assets of the Company  distributed,  which it would have been
entitled  to receive  had it  exercised  these  conversion  rights  prior to the
happening of any of the foregoing events.

     3.6. Notice to Holder. If, at any time while this Debenture is outstanding,
the Company  shall pay any dividend  payable in cash or in Common  Stock,  shall
offer to the holders of its Common  Stock for  subscription  or purchase by them
any  shares of stock of any  class or any  other  rights,  shall  enter  into an
agreement to merge or consolidate  with another  corporation,  shall propose any
capital  reorganization or reclassification of the capital stock of the Company,
including any  subdivision or combination  of its  outstanding  shares of Common
Stock or there shall be  contemplated  a voluntary or  involuntary  dissolution,
liquidation or winding up of the Company, the Company shall cause notice thereof
to be mailed to the registered Holder of this Debenture at its address appearing
on the registration books of the Company, at least thirty (30) days prior to the
record  date as of which  holders  of Common  Stock  shall  participate  in such
dividend,  distribution  or subscription or other rights or at least thirty (30)
days prior to the effective date of the merger,  consolidation,  reorganization,
reclassification or dissolution. If, at any time prior to the earlier of (a) the
Maturity Date, or (b) the Conversion of the Debenture, the number of outstanding
shares of Common Stock is (i) increased by a stock dividend payable in shares of
Common Stock or by a subdivision or split up of shares of Common Stock,  or (ii)
decreased by a combination of shares of Common Stock, then,  simultaneously with
the  occurrence  of  such  event,   the  Conversion   Price  shall  be  adjusted
automatically  to a new amount equal to the product of (A) the Conversion  Price
in effect on such record date and (B) the quotient  obtained by dividing (x) the
number of shares of Common Stock outstanding on such record date (without giving
effect to the events  referred to in the  foregoing  clauses (i) or (ii)) by (y)
the number of shares of Common  Stock  which  would be  outstanding  immediately
after the event referred to in the foregoing clauses (i) or (ii).

     3.7. Adjustments to Conversion Price. The Conversion Price shall be subject
to adjustment from time to time in accordance with this Section 3.7.

     The  Conversion  Price in effect  from  time to time  shall be  subject  to
adjustment as follows:

     (a) Until such time as the Company completes a Subsequent Material Offering
(as defined in Section 3.7(d)  hereof),  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 or exchangeable  for, Common
Stock  (such  convertible  or  exchangeable  stock or  securities  being  herein
collectively referred to as "Convertible  Securities"),  including in connection
with a Subsequent Material Offering, other than:

     (i) shares issued in a transaction described in Section (c) of this Section
3.7; or

     (ii) shares  issued,  subdivided or combined in  transactions  described in
Section  3.5 if and to the  extent  that the  number of  shares of Common  Stock
received upon conversion of this Debenture  shall have been previously  adjusted
pursuant to Section 3.5 as a result of such issuance, subdivision or combination
of such  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,  except as
otherwise provided in Subsection 3.7 (b) hereof,  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) If at any time  following  the  Company's  completion  of a  Subsequent
Material  Offering the Company  shall grant or issue any shares of Common Stock,
or grant or issue any Convertible Securities, other than:

     (i) shares issued in a transaction described in Section (c) of this Section
3.7; or

     (ii) shares  issued,  subdivided or combined in  transactions  described in
Section  3.5 if and to the  extent  that the  number of  shares of Common  Stock
received upon conversion of this Debenture  shall have been previously  adjusted
pursuant to Section 3.5 as a result of such issuance, subdivision or combination
of such  securities;  for a consideration  per share which is less than the Fair
Market Value (as hereinafter  defined) of the Common Stock,  then the Applicable
Conversion  Price  shall,  and  thereafter  upon  each  issuance  or sale  for a
consideration  per share which is less than the Fair Market  Value of the Common
Stock, the Applicable Conversion Price shall,  simultaneously with such issuance
or sale,  be adjusted,  so that the  Applicable  Conversion  Price shall equal a
price  determined by multiplying the Applicable  Conversion Price by a fraction,
of which:

     (A) the  numerator  shall be the sum of (i) the  total  number of shares of
Common Stock outstanding when the Applicable  Conversion Price became effective,
plus (ii) the number of shares of Common Stock which the aggregate consideration
received,  as determined in accordance with Subsection  3.7(e), for the issuance
or sale of such additional  Common Stock or Convertible  Securities deemed to be
an issuance of Common Stock as provided in Subsection 3.7(f), would purchase

     (including any  consideration  received by the Company upon the issuance of
any shares of Common Stock since the date the Applicable Conversion Price became
effective not previously included in any computation  resulting in an adjustment
pursuant to this Section 3.7(b)) at the Fair Market Value of the
Common Stock; and

     (B) the  denominator  shall be the total  number of Shares of Common  Stock
outstanding  (or deemed to be  outstanding  as  provided  in  Subsection  3.7(f)
hereof) immediately after the issuance or sale of such additional shares.

     For purposes of this Section 3.7,  "Fair Market  Value",  in respect of any
such issuance or sale, shall mean the average of the closing price of the Common
Stock for each of the 20 consecutive trading days prior to such issuance or sale
on the  principal  national  securities  exchange  on which the Common  Stock is
traded;  or if,  during such period,  shares of Common Stock are not listed on a
national  securities  exchange  but are quoted on the  National  Association  of
Securities Dealers Automatic Quotation System ("NASDAQ") National Market System,
the closing  price per share as reported by such system  during such period,  or
the  average  of  the  bid  and  asked   prices  of  the  Common  Stock  in  the
over-the-counter market at the close of trading during such period if the shares
are not traded on an exchange or listed on the NASDAQ National Market System; or
if the Common  Stock is not traded on a national  securities  exchange or in the
over-the-counter market, the fair market value of a share of Common Stock during
such period as determined in good faith by the Board of Directors.

     If, however, the Applicable  Conversion Price thus obtained would result in
the issuance of a lesser number of shares upon  conversion  than would be issued
at the initial  Conversion  Price specified in Section 3.1, as appropriate,  the
Applicable Conversion Price shall be such initial Conversion Price.

     Upon each  adjustment  of the  Conversion  Price  solely  pursuant  to this
Section  3.7(b),  the Holder  shall  thereafter  be  entitled  to  acquire  upon
conversion under Section 3.1 or Section 3.2, at the Applicable Conversion Price,
the number of shares of Common Stock  obtainable by  multiplying  the Conversion
Price in effect  immediately prior to such adjustment by the number of shares of
Common Stock  acquirable  immediately  prior to such adjustment and dividing the
product  thereof  by  the  Applicable   Conversion  Price  resulting  from  such
adjustment.

     (c)  Anything  in this  Section  3.7 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 shares of Common Stock or Convertible  Securities
issued in satisfaction  of interest  payments on the Debentures and the Existing
Debentures  (as defined in the Purchase  Agreement),  including  the issuance of
Common  Stock or  Convertible  Securities  issued in  satisfaction  of  interest
payments on debenture  instruments  issued by the Company in satisfaction of the
interest payments on the Debentures and Existing Debentures; or

     (iv) the  issuance of any shares of Common  Stock  pursuant to the grant or
exercise of Convertible Securities outstanding as of the date hereof, including,
without  limitation,  the  Debentures  (as  defined in the  Purchase  Agreement)
(exclusive of any subsequent amendments thereto); or

     (v) the issuance of shares of Common Stock pursuant to the Recapitalization
Agreement.

     (d) For purposes  hereof,  "Subsequent  Material  Offering"  shall mean the
grant or  issuance  of shares  of Common  Stock,  or the  grant or  issuance  of
Convertible  Securities,  to  unaffiliated  third  parties  during any six-month
period for an aggregate  gross  consideration  (determined  in  accordance  with
Subsection 3.7 (e) hereof) of at least ten million dollars  ($10,000,000)  for a
consideration  per share  that is in excess  of the then  Applicable  Conversion
Price.

     (e) For the purpose of Subsections 3.7(a), 3.7(b) and 3.7(d), 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.

     (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.

     (f) For purposes of the adjustment  provided for in Subsections  3.7(a) and
3.7(b) above, 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.

     (g)  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  (a) 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 (b) had all subsequent  adjustments  been
made  only on the  basis  of the  Conversion  Price  as  readjusted  under  this
Subsection 3.7(g) for all transactions  (which would have affected such adjusted
Conversion   Price)  made  after  the  issuance  or  sale  of  such  Convertible
Securities.

     (h)  Anything  in this  Section  3.7 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  Section  3.7(h) are not  required to be made shall be carried  forward and
taken into account in making subsequent adjustments. All calculations under this
Section 3.7 shall be made to the nearest cent.

     (i) 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.

     3.8.  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 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.

     If securities  deliverable  upon conversion of this Debenture,  as provided
above,  are  themselves  convertible  into the  securities  of an affiliate of a
corporation  formed,  surviving  or  otherwise  affected  by the merger or other
transaction, that issuer shall join in the supplemental Debenture which shall so
provide. If this section applies, Section 3.5 does not apply.

                                   ARTICLE IV

                                  MISCELLANEOUS

     4.1.  Default.  Upon the  occurrence  of any one or more of the  Events  of

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

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

other remedies to which the Holder may be entitled, the Holder shall be entitled

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  modification or waiver of any provision of this Debenture shall be effective
unless  it  shall  be in  writing  and  signed  by  the  Holder,  and  any  such
modification  or waiver  shall  apply only in the  specific  instance  for which
given.

     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

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

proceeding in any such court.

conversion of this Debenture;  provided,  however, that the Company shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issuance or delivery of any certificates for the Common Stock in
a name other than that of the  Holder in respect of which such  Common  Stock is
issued,  and in such case the Company  shall not be required to issue or deliver
any  certificate  for the Common Stock until the person  requesting the same has
paid to the Company the amount of such tax or has  established  to the Company's
satisfaction that such tax has been paid.

will be required to modify, amend or waive any provision of Section 1(b) of this
Debentureholders Agreement. The failure of any party to enforce any of the
provisions of this Debentureholders Agreement shall in no way be construed as a
waiver of such provisions and shall not affect the right of such party
thereafter to enforce each and every provision of this Debentureholders
Agreement in accordance with its terms.

     3. Termination. This Debentureholders Agreement shall terminate on the
earliest to occur of (a) mutual written agreement of the parties hereto and (b)

     4. Severability. Whenever possible, each provision of this Agreement shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Debentureholders Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Debentureholders
Agreement shall be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

     5. Entire Agreement. Except as otherwise expressly set forth herein, this
document, the 2002 Purchase Agreement, the 1998 Purchase Agreement, as amended
pursuant to the Amendment to Debenture and Warrant Purchase Agreement dated of
even date, and the 1999 Purchase Agreement, as amended pursuant to the Amendment
to Debenture and Warrant Purchase Agreement dated of even date embody the
complete agreement and understanding among the parties hereto with respect to

     WHEREAS,  unless otherwise  provided in this Agreement,  capitalized  terms
used herein shall have the meanings set forth in Section 14 hereof.

     NOW, THEREFORE,  in consideration of the foregoing and the mutual covenants
and promises contained herein, the parties agree as follows:

     1. Demand Registrations.

     (a) Requests for Registration.  The Holders may request  registration under
the  Securities  Act of all or any  part  of  their  Registrable  Securities  as
provided for below in Section  1(b).  Within ten days after  receipt of any such
request, the Company will give written notice of such requested  registration to
all other Holders of  Registrable  Securities.  The Company will include in such
registration  all  Registrable  Securities with respect to which it has received
written  requests  for  inclusion  therein  within 30 days after  receipt of the
Company's notice.  The Company shall cause its management to cooperate fully and
to use  its  best  efforts  to  support  the  registration  of  the  Registrable
Securities  and  the  sale  of  the  Registrable  Securities  pursuant  to  such
registration as promptly as is practicable.  Such cooperation shall include, but
not be limited to,  management's  attendance  and  reasonable  presentations  in
respect of the Company at road shows with respect to the offering of Registrable
Securities.  The  registration  requested  under this  Section 1 is  referred to
herein as a "Demand Registration".

     (b) Number of Registrations.  The Holders of Registrable Securities will be
entitled to request the following number and types of  registrations:  (i) Galen
shall be  entitled  to  request  two  Demand  Registrations  on Form S-1 (or any
successor  to such form),  (ii)  Watson  shall be entitled to request two Demand
Registrations on Form S-1 (or any successor to such form),  (iii) the Holders of
at least twenty percent (20%) of the  Registrable  Securities  then  outstanding
shall  be  entitled  to  request  one  Demand  Registration  on Form S-1 (or any
successor  to such  form),  provided  that all  Demand  Registrations  requested
pursuant  to  subsections  (i) and (ii) above  shall be deemed to have  occurred
prior to the Demand Registration pursuant to this subsection (iii), and (iv) the
Holders  of  Registrable   Securities  will  be  entitled  to  unlimited  Demand
Registrations on Form S-3 (or any successor to such form), for which the Company
will pay all Registration  Expenses.  A registration  will not count as a Demand
Registration  (x) until it has become  effective,  (y) the Holders have sold, in
the  aggregate,  no less than fifty percent  (50%) of the shares of  Registrable
Securities  requested to be registered in the Demand Registration and (z) if the
offering  of  the  Registrable  Securities  pursuant  to  such  registration  is
interfered  with for any reason by any stop order,  injunction or other order or
requirement  of the Commission  (other than any stop order,  injunction or other
requirement  of the  Commission  prompted  by acts or  omissions  of  Holders of
Registrable  Securities);  provided,  however, that except as otherwise provided
herein whether or not it becomes effective the Company will pay all Registration
Expenses in connection with any registration so initiated.

     (c)  Priority on Demand  Registrations.  If a Demand  Registration  is with
respect to an underwritten  offering,  and the managing  underwriters advise the
Company in writing that in their  opinion the number of  Registrable  Securities
requested to be included  exceeds the number which can be sold in such offering,
the  Company  will  include  in such  registration  such  number of  Registrable
Securities,  which in the opinion of such underwriters,  may be sold,  allocated
among the  Holders  electing  to  participate  pro rata in  accordance  with the
amounts of securities  requested to be so included by the respective Holders. If
the amount of such  Registrable  Securities  does not exceed the maximum  number
which can be sold in such  offering,  the  Company  may  include  such number of
securities which are not Registrable Securities in the Demand Registration which
will not, together with the Holder's Registrable Securities,  exceed the maximum
number which can be sold in the Offering;  provided,  however,  the Company will
not include in any Demand  Registration any securities which are not Registrable
Securities  without  the  written  consent  of  the  Holders  of  sixty-six  and
two-thirds percent (66 2/3%) of the Registrable Securities participating in such
registration.  A registration  shall not count as a Demand  Registration if less
than fifty percent (50%) of the Registrable  Securities which any Holder desires
to include  therein are not  included due to the  determination  of the managing
underwriters referred to in the first sentence of this Section 1(c).

     (d) Restrictions on Demand Registrations. The Company will not be obligated
to effect any Demand  Registration within six months after the effective date of
a previous  registration  in which the Holders of  Registrable  Securities  were
given  piggyback  rights  pursuant  to  Section 2 other than a  registration  of
Registrable  Securities  intended to be offered on a continuous or delayed basis
under  Rule  415 or any  successor  rule  under  the  Securities  Act (a  "Shelf
Registration").

     2. Piggyback Registrations.

     (a) Right to  Piggyback.  Whenever the Company  proposes to register any of
its  securities  under the  Securities  Act  (other  than  pursuant  to a Demand
Registration or pursuant to a registration on Forms S-4 or S-8 or any successors
to  such  forms)  and the  registration  form  to be  used  may be used  for the
registration   and  contemplated   disposition  of  Registrable   Securities  (a
"Piggyback  Registration"),  the Company will give prompt  written notice to all
the  Holders  of  Registrable  Securities.  The  Company  will  include  in such
registration  all  Registrable  Securities with respect to which the Company has
received written requests for inclusion therein within 30 days after the receipt
of the Company's notice, subject to any other priority cutback provisions below.

     (b)  Piggyback  Expenses.  The  Registration  Expenses  of the  Holders  of
Registrable  Securities  in  such  Piggyback  Registration  will  be paid by the
Company.

     (c) Priority on Primary  Registrations.  If a Piggyback  Registration is an
underwritten  primary  registration  on behalf of the Company,  and the managing
underwriters  advise the Company in writing that in their  opinion the number of
securities  requested  to be  included in such  registration  exceeds the number
which  can  be  sold  in  such  offering,  the  Company  will  include  in  such
registration  (i) first,  the  securities  the Company  proposes  to sell,  (ii)
second, the Registrable  Securities,  pro rata in accordance with the amounts of
Registrable   Securities   requested  to  be  so  included  by  each  Requesting
Stockholder,  and (iii) third, any other securities  requested to be included in
such  registration.

     (d) Priority on Secondary Registrations.  If a Piggyback Registration is an
underwritten  secondary  registration  on behalf  of  holders  of the  Company's
securities,  and the managing underwriters advise the Company in writing that in
their  opinion  the  number  of  securities  requested  to be  included  in such
registration exceeds the number which can be sold in such offering,  the Company
will include in such  registration

     (i) first,  the securities  requested to be included therein by the holders
requesting such registration,

     (ii) second,  the Registrable  Securities,  pro rata in accordance with the
amounts of Registrable Securities requested to be so included by each Requesting
Stockholder,  and

     (iii)   third,   other   securities   requested  to  be  included  in  such
registration.

     (e) Other Restrictions. The Company hereby agrees that if it has previously
filed a registration  statement with respect to Registrable  Securities pursuant
to Section 1 or pursuant to this  Section 2, and if such  previous  registration
has not been  withdrawn or  abandoned,  the Company will not file or cause to be
effected any other  registration  of any of its equity  securities or securities
convertible or exchangeable  into or exercisable for its equity securities under
the  Securities  Act except on Form S-8 or any other  similar  form for employee
benefit  plans,  whether  on its own  behalf or at the  request of any holder or
holders of such  securities,  until a period of at least six months has  elapsed
from the effective date of such previous  registration or, if sooner,  until all
Registrable Securities included in such previous registration have been sold.

     3. Holdback Agreements.

     (a) Holders of Registrable Securities.  The Investors and each other Holder
of Registrable  Securities who is or becomes a party to this  Agreement,  agrees
not to effect  any  public  sale or  distribution  of equity  securities  of the
Company,  or any securities  convertible into or exchangeable or exercisable for
such securities,  during the seven days prior to and the 90-day period beginning
on  the  effective  date  of  any  underwritten   Demand   Registration  or  any
underwritten   Piggyback  Registration  except  as  part  of  such  underwritten
registration  or, if sooner,  until all Registrable  Securities  included within
such registration have been sold.

     (b) The  Company.  The Company  agrees (i) not to effect any public sale or
distribution of its equity  securities,  or any securities  convertible  into or
exchangeable or exercisable for such securities,  during the seven days prior to
and the 90-day period beginning on the effective date of any underwritten Demand
Registration or any underwritten  Piggyback  Registration except as part of such
underwritten  registration or pursuant to registrations on Form S-8 or any other
similar form for employee  benefit  plans or, if sooner,  until all  Registrable
Securities included within such registration have been sold, and (ii) to use its
reasonable  best efforts to cause each holder of its equity  securities,  or any
securities  convertible into or exchangeable or exercisable for such securities,
purchased from the Company at any time after the date of this  Agreement  (other
than in a registered  public offering) to agree not to effect any public sale or
distribution  of any such  securities  during such period except as part of such
underwritten  registration,  if  otherwise  permitted  or, if sooner,  until all
Registrable  Securities  included  within  such  registration  have  been  sold;
provided,  however,  that the  provisions of this Section 3(b) shall continue to
apply with respect to a  registration  until the  provisions  of Section 3(a) no
longer apply with respect to such registration.

     (c) Registration Procedures. Whenever the Holders of Registrable Securities
have requested that any Registrable Securities be registered pursuant to Section
1 or 2 of this  Agreement,  the Company shall use its best efforts to effect the
registration and the sale of such Registrable  Securities in accordance with the
intended method of disposition  thereof,  and pursuant thereto the Company shall
as expeditiously as possible:

     (i) prepare and file with the  Commission  a  registration  statement  with
respect to such Registrable Securities,  which registration statement will state
that the  Holders  of  Registrable  Securities  covered  thereby  may sell  such
Registrable  Securities  either  under such  registration  statement  or, at any
Holder's proper  request,  pursuant to Rule 144 (or any successor rule under the
Securities Act), and use its best efforts to cause such  registration  statement
to become  effective  (provided that before filing a  registration  statement or
prospectus or any amendments or supplements thereto, the Company will furnish to
the  counsel  selected  by (A)  Galen,  in the  event of a  Demand  Registration
requested  pursuant to Section  1(b)(i),  (B)  Watson,  in the event of a Demand
Registration  requested  pursuant  to Section  1(b)(ii),  or (C) the  Holders of
sixty- six and  two-thirds  percent  (66  2/3%) of the  Registrable  Securities
included in such registration, in the event of any other registration, copies of
all such documents  proposed to be filed, which documents will be subject to the
review of such counsel);

     (ii) prepare and file with the Commission  such  amendments and supplements
to such registration  statement and the prospectus used in connection  therewith
as may be necessary to keep such registration statement effective for the period
set  forth  in  Section  4(i)  hereof  and  comply  with the  provisions  of the
Securities Act with respect to the disposition of all securities covered by such
registration  statement  during  such  period in  accordance  with the  intended
methods of  disposition  by the sellers  thereof set forth in such  registration
statement;

     (iii)  furnish to each  seller of  Registrable  Securities  such  number of
copies of such registration  statement,  each amendment and supplement  thereto,
the  prospectus  included  in  such  registration   statement   (including  each
preliminary  prospectus)  and such other documents as such seller may reasonably
request in order to facilitate  the  disposition of the  Registrable  Securities
owned by such seller;

     (iv) use its best  efforts to  register  or qualify,  if  applicable,  such
Registrable  Securities  under  such other  securities  or blue sky laws of such
jurisdictions  as any seller  reasonably  requests and do any and all other acts
and things which may be reasonably  necessary or advisable to enable such seller
to  consummate  the  disposition  in  such   jurisdictions  of  the  Registrable
Securities  owned by such seller (provided that the Company will not be required
to (A) qualify  generally to do business in any jurisdiction  where it would not
otherwise be required to qualify but for this subsection,  (B) subject itself to
taxation in any such jurisdiction,  or (C) consent to general service of process
in any such jurisdiction);

     (v) within one business day of its  occurrence,  notify each seller of such
Registrable  Securities,  at any time  when a  prospectus  relating  thereto  is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the  prospectus  included  in such  registration  statement
contains  an  untrue  statement  of a  material  fact or omits to state any fact
necessary to make the statements therein not misleading,  and, at the request of
any such seller,  the Company will promptly prepare a supplement or amendment to
such  prospectus  so that,  as  thereafter  delivered to the  purchasers of such

Company's Common Stock for a period of up to 180 days; and

     (xi)  furnish,  at the  request of any Holder  requesting  registration  of

Securities  are  delivered  to  the  underwriters  for  sale  pursuant  to  such
registration,  or if such  Registrable  Securities  are not being  sold  through

shares of Registrable Securities becomes effective,  (A) a signed opinion, dated

purpose of such registration, addressed to the underwriters, if any, and if such
Registrable  Securities  are not being sold  through  underwriters,  then to the
Holders  making such  request,  as to such matters as such  underwriters  or the
Holders  holding a  majority  of the  Registrable  Securities  included  in such
registration,  as the case may be, may reasonably request; and (B) letters dated

such  accountants,  the financial  statements  and other  financial  data of the
Company  included  in  the  Registration  Statement  or the  prospectus,  or any

any failure of the Company to comply  with the terms of this  Agreement,  or the
disclosure of any adverse development  relating to the Company after the initial
request for  registration by any Holder),  the  registration  statement does not
become  effective,  in  which  case  the  Holders  and  Requesting  Stockholders
requesting  registration  shall bear such Registration  Expenses pro rata on the
basis of the number of their  shares so  included in the  registration  request,
and,  further,  that  such  registration  shall  not  be  counted  as  a  Demand
Registration  pursuant to Section 1.

registration,  qualification or compliance of such Holder's  securities has been
effected  pursuant to this  Agreement,  and each  underwriter,  if any, and each
Person who controls any  underwriter,  against all claims,  losses,  damages and
liabilities (or actions in respect thereof), joint or several, arising out of or
based on any untrue  statement (or alleged untrue  statement) of a material fact
contained in any registration statement,  prospectus, offering circular or other
document (including any related registration statement notification or the like)
incident to any such registration,  qualification or compliance, or based on any
omission (or alleged  omission) to state  therein a material fact required to be
stated therein or necessary to make the statements  therein not  misleading,  or
any  violation by the Company of the  Securities  Act or any rule or  regulation
thereunder applicable to the Company and relating to action or inaction required
of the  Company  in  connection  with any such  registration,  qualification  or
compliance,  and will  reimburse  each  such  Holder,  each  Holder's  officers,
directors,  employees, agents, members and partners, and each Person controlling
each such Holder,  each such  underwriter  and each Person who controls any such
underwriter,  for any  legal  and any  other  expenses  reasonably  incurred  in
connection  with  investigating  or  defending  any such  claim,  loss,  damage,
liability or action, provided that the Company will not be liable to a Holder in
any such case to the extent  that any such claim,  loss,  damage,  liability  or
action arises out of or is based on any untrue statement or omission of material
fact based upon written  information  furnished to the Company by such Holder or
underwriter and stated to be specifically for use therein.

     (b) Each Holder and Requesting  Stockholder will severally not jointly,  if
Registrable  Securities  held by it are included in the  securities  as to which
such registration,  qualification or compliance is being effected, indemnify the
Company,  each of the Company's directors and officers and each underwriter,  if
any, of the Company's  securities covered by such registration  statement,  each
Person who  controls the Company or such  underwriter  within the meaning of the
Securities  Act and the rules and  regulations  thereunder,  each other  Holder,
Requesting  Stockholder  or any  other  holder  of  securities  included  in the
offering and each of their respective officers,  directors,  employees,  agents,
members and partners, and each Person controlling such other Holder,  Requesting
Stockholder  and any other  holders  of  securities  included  in the  offering,
against  all claims,  losses,  damages  and  liabilities  (or actions in respect
thereof),  joint or several, arising out of or based on any untrue statement (or
alleged untrue  statement) of a material fact contained in any such registration
statement,  prospectus, offering circular or other document incident to any such
registration,  qualification or compliance, or based on any omission (or alleged
omission)  to state  therein a material  fact  required to be stated  therein or
necessary to make the statements therein not misleading,  and will reimburse the
Company, its officers and directors,  each underwriter,  each Person controlling
the Company or such underwriter,  each other Holder and Requesting Stockholders,
their officers,  directors,  employees,  agents,  members,  partners and control
persons for any legal or any other  expenses  reasonably  incurred in connection
with  investigating  or defending  any such claim,  loss,  damage,  liability or
action,  in each case to the extent,  but only to the  extent,  that such untrue
statement (or alleged  untrue  statement)  or omission (or alleged  omission) is
made in such  registration  statement,  prospectus,  offering  circular or other
document in reliance upon and in conformity with written  information  furnished
to the  Company  by such  Holder  or  Requesting  Stockholder  and  stated to be
specifically for use therein;  provided,  however,  that the obligations of each
such Holder and Requesting  Stockholder  hereunder shall be limited to an amount
equal to the net proceeds (after deduction of underwriting discounts and selling
commissions,  if any) received by each such Holder or Requesting  Stockholder of
securities sold as contemplated herein.

     (c) Each  party  entitled  to  indemnification  under  this  Section 5 (the
"Indemnified  Party")  shall  give  notice  to the  party  required  to  provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom,  provided  that  counsel for the  Indemnifying
Party,  who shall conduct the defense of such claim or any litigation  resulting
therefrom,  shall be approved by the Indemnified Party (whose approval shall not
be  unreasonably  withheld) and the  Indemnified  Party may  participate in such
defense at such party's  expense,  and provided  further that the failure of any
Indemnified  Party to give  notice as  provided  herein  shall not  relieve  the
Indemnifying  Party of its obligations  under this Agreement unless such failure
has had a material  adverse effect on such claim.  The parties to this Agreement
reserve any rights to claim under this Agreement for damages  actually  incurred
by reason of any failure of the  Indemnified  Party to give  prompt  notice of a
claim. To the extent counsel for the Indemnifying  Party shall in such counsel's
reasonable  judgment,  have a conflict in representing  an Indemnified  Party in
conjunction  with the  Indemnifying  Party or other  Indemnified  Parties,  such
Indemnified  Party shall be  entitled to separate  counsel at the expense of the
Indemnifying  Party  subject to the approval of such counsel by the  Indemnified
Party (whose  approval  shall not be  unreasonably  withheld).  No  Indemnifying
Party,  in the defense of any such claim or litigation,  shall,  except with the
consent of each  Indemnified  Party,  consent to entry of any  judgment or enter
into any settlement which does not include as an unconditional  term thereof the
giving by the claimant or plaintiff to such Indemnified  Party of a release from
all liability in respect of such claim or  litigation.  Each  Indemnified  Party
shall furnish such  information  regarding itself or the claim in question as an
Indemnifying  Party may reasonably request in writing and as shall be reasonably
required  in  connection  with the  defense  of such  claim  and any  litigation
resulting therefrom.

     6. Restrictive Legend. Each certificate  representing (a) the Securities or
(b) any Shares or other  securities  issued in respect  thereof,  upon any stock
split, stock dividend, recapitalization,  merger, consolidation or similar event
shall be stamped or otherwise  imprinted with a legend in the following form (in
addition to any legend required under  applicable  state securities laws and any
other applicable agreement(s)):

          "THIS WARRANT/DEBENTURE [AND THE COMMON STOCK ISSUABLE UPON
          COVERSION HEREOF] HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), NOR ANY STATE
          SECURITIES LAW AND MAY NOT BE PLEDGED, SOLD, ASSIGNED,
          HYPOTHECATED OR OTHERWISE TRANSFERRED UNTIL (1) A REGISTRATION
          STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE ACT AND
          ANY APPLICABLE STATE SECURITIES LAWS OR (2) THE COMPANY
          RECEIVES AN OPINION OF COUNSEL TO THE COMPANY OR OTHER COUNSEL
          TO THE HOLDER OF SUCH [WARRANT/DEBENTURE AND/OR COMMON STOCK]
          REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH
          [WARRANT/DEBENTURE AND/OR COMMON STOCK] MAY BE PLEDGED, SOLD,
          ASSIGNED, HYPOTHECATED OR TRANSFERRED WITHOUT AN EFFECTIVE
          REGISTRATION STATEMENT UNDER THE ACT OR APPLICABLE STATE
          SECURITIES LAWS."

     7. Information by the Holders and Requesting  Stockholders.  Each Holder of
Registrable  Securities,  and each  Requesting  Stockholder  holding  securities
included in any  registration,  shall  furnish to the Company  such  information
regarding such Holder or Requesting Stockholder and the distribution proposed by
such Holder or Requesting  Stockholder as the Company may reasonably  request in
writing and as shall be reasonably required in connection with any registration,
qualification or compliance referred to in this Agreement.

     8. Limitations on Registration of Issues of Securities.  From and after the
date of this Agreement,  the Company shall not enter into any agreement with any
holder or prospective holder of any securities of the Company giving such holder
or  prospective  holder  the  right to  require  the  Company  to  register  any
securities of the Company that are more  favorable to such holder or prospective
holder than the rights granted under this Agreement.

     9. Rule 144  Reporting.  With a view to making  available  the  benefits of
certain rules and regulations of the Commission which may permit the sale of the
Restricted Securities to the public without registration, the Company agrees to:

     (a)  make  and  keep  public  information  available  as  those  terms  are
understood  and  defined  and  interpreted  in and  under  Rule  144  under  the
Securities Act ("Rule 144"), at all times from and after the date hereof;

     (b) file with the  Commission  in a timely  manner  all  reports  and other
documents  required of the Company under the Securities Act and the Exchange Act
at any time after it has become subject to such reporting requirements; and

     (c) so long as the Holders own any  Restricted  Securities,  furnish to the
Holders  forthwith  upon  request a written  statement  by the Company as to its
compliance with the reporting requirements of Rule 144 and of the Securities Act
and the Exchange Act (at any time after it has become  subject to such reporting
requirements),  a copy of the most  recent  annual  or  quarterly  report of the
Company,  and such  other  reports  and  documents  so filed as any  Holder  may
reasonably  request  in  availing  itself  of  any  rule  or  regulation  of the
Commission allowing any Holder to sell any such securities without registration.

     10.  Participation in Underwritten  Registrations.  Subject to the right of
any Holder or Holders to withdraw  any request for  registration,  no Person may
participate in any  underwritten  registration  hereunder unless such Person (a)
agrees  to  sell  such  Person's   securities  on  the  basis  provided  in  any
underwriting  arrangements approved by the Persons entitled hereunder to approve
such  arrangements  and (b) completes and executes all  reasonable and customary
questionnaires,  powers of attorney,  indemnities,  underwriting  agreements and
other documents required under the terms of such underwriting arrangements.

     11.   Selection  of  Underwriters.   If  any  Demand   Registration  is  an
underwritten  offering,  (a)  Galen,  in  the  event  of a  Demand  Registration
requested  pursuant to Section  1(b)(i),  (b)  Watson,  in the event of a Demand
Registration  requested  pursuant  to Section  1(b)(ii),  and (c) the Holders of
sixty-six  and  two-thirds  percent  (66  2/3%)  of the  Registrable  Securities
included in such registration, in the event of any other registration shall have
the  right to select  the  investment  banking  firm to be lead  manager  of the
offering,  subject to the approval of the Company  (which  approval  will not be
unreasonably  withheld). If any registration other than a Demand Registration is
an  underwritten  offering,  the  Company  will  have the  right to  select  the
investment  banking  firm to be lead  manager  of the  offering,  subject to the
approval of the Holders of  sixty-six  and  two-thirds  percent (66 2/3%) of the
Registrable Securities included in such registration (which approval will not be
unreasonably withheld).

     12. Termination of Registration  Rights. The rights of Holders to request a
Demand  Registration or participate in a Piggyback  Registration shall expire on
March 31, 2008.

the Bridge  Warrants in  connection  with Halsey's  release of the  Galen/Oracle
Reserved Shares in accordance with paragraph 1 above and agrees that such action
shall not  constitute a Default or an Event of Default  under the 1998  Purchase
Agreement,  the 1998 Debentures,  the 1998 Warrants,  the Bridge Loan Agreement,
the Bridge Notes, or the Bridge Warrants.

     4. Each of the Galen  Entities and Oracle hereby waives the  application of
(i) Section 9.14 of the 1999  Purchase  Agreement,  (ii) Section 3.4 of the 1999
Debentures,  and (iii)  Section  1(c) of the 1999  Warrants in  connection  with
Halsey's  release  of  the  Galen/Oracle  Reserved  Shares  in  accordance  with
paragraph 1 above and agrees that such action shall not  constitute a Default or
an Event of Default under the 1999 Purchase Agreement,  the 1999 Debentures,  or
the 1999 Warrants.

     5. Each of the Waiving Parties hereby agree to execute (without cost to any
other party and unreasonable  delay), such additional  documents and instruments
as may be required in order to effect the release of Halsey's reserved shares of
Common Stock as provided above.

     6. Halsey hereby agrees to maintain the  Care/Essex/Watson  Reserved Shares
for the sole benefit of Care  Capital  Investments  II, LP, and Essex  Woodlands
Health Ventures Fund V and Watson.

     7. This  Agreement may be executed in any number of  counterparts,  each of
which shall be an  original,  but all of which  together  shall  constitute  one
instrument.

     8. No amendment,  waiver or modification of any provision of this Agreement
shall be valid unless the same shall be in writing and signed by all the parties
hereto.

     9. The provisions of this  Agreement  shall inure to the benefit of, and be
binding  upon and  enforceable  by and  against,  the  parties  hereto and their
respective successors, assigns, heirs, executors and administrators.

     10.  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.

     11. In case any provision of this  Agreement  shall be invalid,  illegal or
unenforceable,  the  validity,  legality  and  enforceability  of the  remaining
