The following table sets forth certain information as of October 31, 2003, concerning the ownership of Common Stock and Series B Convertible Preferred Stock by (i) each stockholder of the Company known by the Company to be the beneficial owner of more than 5% of the outstanding shares of Common Stock or Preferred Stock, (ii) each current member of the Board of Directors of the Company and (iii) each executive officer of the Company.

Beneficial ownership is determined in accordance with Rule 13d-3 of the Securities Exchange Act of 1934, as amended, and includes all shares over which the beneficial owner exercises voting or investment power. Options and warrants to purchase Common Stock or Preferred Stock of the Company that are presently exercisable or exercisable within 60 days of October 31, 2003 and shares of Preferred Stock of the Company that are presently convertible or convertible within 60 days of October 31, 2003 that are held by the persons listed below are included in the total number of shares beneficially owned for such person and are considered outstanding for the purpose of calculating the percentage ownership of such holder. The Company has relied on information supplied by its officers, directors and certain stockholders and on information contained in filings with the SEC in completing the table below. Except as otherwise indicated, and subject to community property laws where applicable, we believe, based on information provided by these persons, that the persons named in the table have sole voting and investment power with respect to all shares of Common Stock or Preferred Stock of the Company shown as beneficially owned by them.

(4) Includes 4,294,399 shares of Common Stock beneficially held by Mark Capital LLC. Mr. Levine is the managing member of Mark Capital LLC. Authorization or Issuance of Securities Otherwise Than for Exchange.

The Amendment will increase the authorized number of shares of Common Stock of the Company from 50,000,000 to 100,000,000. The increase in the authorized number of shares of Common Stock of the Company will provide the Company with the ability to continue to raise financing through the sale of shares of its Common Stock in order to continue the Company's research and development efforts including the funding of clinical trials of its drug candidates. The Company is actively seeking such financing. The Company cannot guarantee that additional funding will be available on acceptable terms, or at all. The Company does not currently have any written or oral plans or arrangements pursuant to which it is obligated to issue any of the shares of Common Stock authorized by the Amendment. The Company does not plan to solicit the vote of security holders prior to the issuance of any of the additional shares authorized pursuant to the Amendment. The shares of Common Stock to be authorized pursuant to the Amendment could be used by the board of directors of the Company to discourage, delay, prevent or make more difficult the acquisition of a controlling interest of the Company by a potential acquirer pursuant to which stockholders could otherwise receive a premium over the market price for their shares of Common Stock. The board of directors of the Company could issue the shares of Common Stock to be authorized pursuant to the Amendment to purchasers that may support the current board of directors or management of the Company in opposing an unsolicited attempt to acquire control of the Company and also thereby dilute the stock ownership and voting power of any such unsolicited potential acquirer. Although the Amendment may have potentially adverse antitakeover effects, it was not adopted pursuant to any actual or perceived threat of a takeover. Financial and Other Information. The response to this item is incorporated by reference from (a) the sections titled "Financial Information" and "Management's Discussion and Analysis or Plan of Operation" in the Company's Quarterly Report on Form 10-QSB filed August 14, 2003; and the Company's Current Report on Form 8-K filed February 10, 2003. Voting Procedures.
