(the "Company") to which this note relates are held directly by Oracle Strategic Partners, L.P. ("Strategic Partners"). Strategic Partners holds, as of the date of this Form 4, 3,649,461 shares of Common Stock of the Company ("Common Stock") as well as Options for Common Stock ("Options") and 5% Convertible Senior Secured Debentures ("Debentures") of the Company, presently convertible into 30,000 shares and 18,925,784 shares of Common Stock, respectively. Oracle Strategic Capital, L.L.C. ("Strategic Capital") serves as the general partner of Strategic Partners. The undersigned is the managing member of Strategic Capital. The undersigned does not directly own any warrants for Common Stock ("Warrants"), Debentures, Options or Common Stock of the Company. In accordance with Instruction 4(b)(iv), the entire number of such Debentures, Warrants, Options and shares of Common Stock, held by Strategic Partners, related to the transactions reported on this Form 4, is reported herein. The undersigned disclaims any beneficial ownership of the securities to which this Form 4 relates for purposes of Section 16 of the Securities Exchange Act of 1934, except as such securities representing the undersigned's pro rata interest in, and interest in the profits of, Strategic Partners. (2) A series of transactions involving the Company were described in the Company's Current Report on Form 8-K, filed on December 27, 2002 (the "Form 8-K") In connection with these transactions, Strategic Partners received certain anti-dilution adjustments with respect to Warrants that it directly owned. Specifically, Warrants for 1,010,100 shares of Common Stock, with an exercise price of $1.404, were adjusted to represent Warrants for 2,393,478 shares of Common Stock with an exercise price of $0.59. In addition, Warrants for 1,010,100 shares of Common Stock, with an exercise price of $2.285 were adjusted to represent Warrants for 2,393,478 shares of Common Stock with an exercise price of $0.96. These two sets of Warrants were then exchanged, in a cashless exercise (as valued pursuant to a Black-Scholes model), for 1,895,824 and 1,753,637 shares of Common Stock, respectively, or 3,649,461 shares in the aggregate. Strategic Partners received the documentation formalizing these transactions on February 25, 2003. As per Rule 16a-4(b) of the Securities Exchange Act of 1934, the exercise of the Warrants reported herein is set forth as a purchase of the underlying Common Stock and a closing of a derivative security position. (3) In connection with the transaction described in the Form 8-K, existing Debentures held by Strategic Partners were amended to extend their maturity date until March 31, 2006 and their applicable conversion prices for conversion into Common Stock were revised in accordance with their anti-dilution provisions. Strategic Partners holds Debentures in the principal amounts of: $10,000,000; $125,000; $126,562; $128,144; $129,746; $131,368; $133,010; $134,672; $136,356; $138,060; $139,786; $141,534; and $143,302. The conversion prices for such Debentures per share of Common Stock are, respectively, $0.6135, $0.7525, $0.4862, $0.3964, $0.2735, $0.4501; $0.9701, $0.9701; $0.8128; $0.8827; $0.7516; $0.7667; and $1.0200. The Debentures are therefore convertible, respectively, into the following amounts of Common Stock: 16,298,644; 166,110; 260,238; 323,268; 474,436; 291,858; 137,104; 138,818; 167,756; 156,400; 185,974; 184,598; and 140,492. The foregoing Debentures, except for the $10,000,000 initial Debenture, were received by Strategic Partners as interest payments. Interest on all the Debentures held by Strategic Partners is paid quarterly on each January 1, April 1, July 1 and October 1. /s/ Larry N.
