Item 3. Source and Amount of Funds and Other Consideration.

    Lipid has entered into a Stock Purchase Agreement with Sun NZ, L.L.C. ("Sun NZ"), dated July 9, 2001 (the "Stock Purchase Agreement"), to purchase 1,505,402 shares of the Issuer's common stock from Sun NZ.

The amount of funds to be used to purchase the shares of the Issuer's common stock is $12,043,216.

Item 4. Purpose of Transaction.

    On July 9, 2001, Lipid entered into a Stock Purchase Agreement with Sun NZ to purchase shares of the Issuer's common stock. Concurrently, Lipid entered into an Agreement and Plan of Merger (the "Merger Agreement") with the Issuer, which provides that Lipid will merge with and into the Issuer (the "Merger"), with the Issuer being the surviving corporation after the Merger. Under the terms of the Stock Purchase Agreement, Sun NZ has agreed to vote all the shares of the Issuer's common stock

4

that it owns in favor of the Merger. The closing of each of the Merger and the Stock Purchase Agreement is conditioned on the closing of the other.

    The name of the surviving corporation will be changed to Lipid Sciences, Inc. If the Merger is completed, Lipid stockholders will receive 1.55902 shares of the Issuer's common stock for each share of Lipid's common stock, and the holders of warrants and options to acquire shares of Lipid's common stock will receive the right to acquire equivalent shares of Issuer's common stock, based on the share exchange ratio set forth in the Merger Agreement. The authorized shares of the Issuer's capital stock will be increased from 40,000,000 to 85,000,000 shares, of which 75,000,000 will be designated shares of common stock and 10,000,000 shares will be designated as shares of preferred stock.

    Following the Merger, the Issuer's Articles of Incorporation and bylaws will govern the surviving corporation. The Issuer's Articles of Incorporation will be amended to remove the requirement that each director of the Issuer also must be a stockholder of the Issuer and to provide the right of Sun NZ to nominate up to one-third of the number of the Issuer's directors while Sun NZ owns a certain minimum number of the Issuer's shares of common stock.

    Under the terms of the Merger Agreement, following the closing, Messrs. William A. Pope, Christopher A. Marlett, Phil Radlick, Bill E. Cham, Gary S. Roubin and Frank M. Placenti will be the directors of the surviving corporation. Each director's term will run for the time remaining in that director's class. In addition, as a condition of the Merger, the seven current officers of Lipid will continue to serve in their respective capacities as officers of the surviving corporation. Messrs. R. Randy Stolworthy and Jerome L. Joseph, currently officers of the Issuer, will remain employed following the Merger to assist with the orderly liquidation of substantially all of the Issuer's assets.

    After the Merger is completed, Lipid currently intends that the business of the surviving corporation will primarily be that of Lipid prior to the Merger. The Issuer and Lipid expect to liquidate the assets held by NZ immediately prior to the merger over a period of time in order to fund the operations of the surviving corporation.

    Consummation of the Merger is subject to certain customary closing conditions, including: (1) without supplementation, the representations and warranties of the Issuer and Lipid set forth in the Merger Agreement are materially true and correct in all respects as of the Merger's closing date; (2) the Issuer and Lipid have performed and complied with all of their covenants, obligations and agreements contained in the Merger Agreement; (3) the Issuer and Lipid have received written evidence satisfactory to them that all consents and approvals required for the consummation of the transactions contemplated hereby have been obtained, and all required filings have been made; (4) the Issuer and Lipid have received all of the agreements, documents and items specified in the Merger Agreement; (5) each of the Issuer or Lipid has not suffered any material adverse change in its assets, liabilities, prospects, financial condition or business; (6) no action or proceeding by any governmental authority or other person has been instituted or threatened that is likely to have a material adverse effect on either the Issuer or Lipid, or could enjoin, restrain or prohibit, or could result in substantial damages in respect of, any provision of the Merger Agreement or the consummation of any related transactions; (7) the Issuer and Lipid have received certain legal opinions; (8) the stockholders of the Issuer and Lipid have approved the Merger; (9) the registration statement on Form S-4 has been declared effective by the SEC and no stop order is threatened or effective against the registration statement; (8) the fairness opinion of the Issuer's financial advisor has not been withdrawn; (10) the Stock Purchase Agreement is in full force and effect and the transactions contemplated thereby have been consummated immediately prior to the Merger; (11) the Issuer's stockholders have approved the amendments to the Issuer's certificate of incorporation to the effect that the Issuer's name will be changed to Lipid Sciences, Inc., the shares of the Issuer's authorized stock will be increased to 85,000,000 and the Issuer's authorized shares of common stock will be increased to 75,000,000, the requirement that each of the Issuer's directors must also be a stockholder has been removed, and Sun NZ shall have the right to nominate persons to the board as set forth in the Stock Purchase

Agreement; (12) the Issuer's 2001 Performance Equity Plan has been approved; (13) the directors identified in the Merger Agreement as directors of the surviving corporation have been elected as directors as of the effective time, as that term is defined in the Merger Agreement; (14) during the period commencing on the date the registration statement on Form S-4 is declared effective by the SEC and the effective time, as that term is defined in the Merger Agreement, a volume of 250,000 shares or more of the Issuer's common stock has traded at a sale price per share of $6.50 or more; (15) Lipid has entered into a consulting agreement with Dr. Bill E. Cham, which agreement will be reasonably satisfactory to the Issuer; (16) Lipid has entered into agreements with each of its employees as of the date of the Merger Agreement that provide that their work is the property of Lipid and otherwise protects the intellectual property of Lipid; and (17) the Issuer's directors in office immediately prior to the effective time, as that term is defined in the Merger Agreement, will tender their resignation as the Issuer's directors.

Item 5. Interest in Securities of the Issuer.

    Lipid has the right to acquire 1,505,402 shares, or 22.1% of the Issuer's common stock pursuant to the Stock Purchase Agreement. Lipid beneficially owns 2,985,583 shares (the "Voting Securities"), or 43.8% of the Issuer's common stock because Lipid has the power to direct the voting of these shares of the Issuer's common stock under the terms of the Stock Purchase Agreement as follows: (a) in favor of the Merger Agreement and the Merger, the approval of the terms thereof and all the transactions contemplated thereby, and any other transaction proposed by the Issuer, including, but not limited to voting in favor of each of the proposals to (i) change the name of the Issuer to "Lipid Sciences, Inc.," (ii) increase the capitalization of the Issuer, (iii) elect the persons specified in the Merger Agreement as directors of the Issuer, (iv) eliminate the provision in the Issuer's Articles of Incorporation (the "Articles") that each director must also be a stockholder of the Issuer, (v) add a provision to the Articles relating to Sun NZ's right to nominate persons to the Issuer's board of directors, and (vi) approve the Issuer's 2001 Performance Equity Plan; (b) against any action or agreement that would result in a breach in any material respect of any covenant, representation or warranty or any other obligation or agreement of the Issuer under the Merger Agreement or of Sun NZ under the Stock Purchase Agreement; and (c) against any of the following, except as contemplated in the Merger Agreement: (i) any extraordinary corporate transaction or (ii) a sale or transfer of a material amount of assets of the Issuer or its subsidiaries and affiliates or a reorganization, recapitalization or liquidation of the Issuer.

    Lipid's power to direct the voting of the Voting Securities will be revoked if the "fundamental economic provisions" of the Merger Agreement are modified by the Issuer and Lipid.

If the Merger is consummated, the Purchased Shares acquired by Lipid pursuant to the Stock Purchase Agreement will be cancelled.
