        (c)  in favor of each other matter relating to the consummation of the transactions contemplated by the Merger Agreement.

The Voting Agreements further require that HCV and Mr. Horner, as applicable, at the time they enter into the applicable Voting Agreement, deliver to Biosearch an irrevocable proxy with respect to their shares subject to the Voting Agreement, allowing Biosearch's Chief Executive Officer and/or President, or their successors, to vote in favor of or against, as applicable, the matters set forth in (a) through (c) above. Each of HCV and Mr. Horner has delivered such a proxy to Biosearch.

Except as provided above, the Voting Agreements terminate on the earlier of (i) the termination of the Merger Agreement in accordance with Article VII thereof, and (ii) the consummation of the Merger.

The foregoing description of the Voting Agreements is qualified in its entirety by reference to the full text of such agreements, copies of which are attached hereto as Exhibits 1 and 2 and incorporated by reference herein.

Stockholders Agreement

On July 30, 2002, Mr. Horner and Drs. Cavanaugh, Quarta and Parenti entered into the Stockholders Agreement, which provides that the parties thereto shall take such action as may be required so that all of their shares of Common Stock held by them (the "Subject Shares") are voted at all Versicor stockholders meetings:

          (i)  for nominees to Versicor's board of directors who have been recommended by the board of directors according to the procedures set forth in Versicor's amended and restated bylaws, which will be in effect at the effective time of the Merger, and

        (ii)  on all other matters submitted to the holders of Common Shares with respect to any Significant Event (as defined below) in accordance with the recommendations of the board of directors.

As used in the Stockholders Agreement, the term "Significant Event" means any charter or bylaw amendment, acquisition or disposition of assets (by way of merger, consolidation or otherwise), change in capitalization, liquidation or other action out of the ordinary course of business of Versicor. The parties are also required to take such action as may be required so that all Subject Shares owned by the party shall be present in person or by proxy at all duly noticed and convened meetings of Versicor stockholders, so that the Subject Shares owned by such party may be counted for the purpose of determining the presence of a quorum at such meetings.

The Stockholders Agreement also prohibits the parties from depositing any of their Subject Shares in a voting trust or making any other arrangement or agreement with respect to the voting of the Subject Shares. Furthermore, the Stockholders Agreement provides, among other things, that the parties shall not directly or indirectly solicit proxies or become a "participant" in a "solicitation" in opposition to the recommendation of the board of directors with respect to any matter or in any "election contest" relating to the election of directors of Versicor (as such terms are defined in Regulation 14A under the Exchange Act).
