     WHEREAS, in consideration of the execution of the Purchase Agreement by Mimix, Shareholder (in his or her capacity as such) agrees to vote the Shares and the New Shares (each as defined below) of the Company over which Shareholder has voting power to approve of the Transaction as contemplated by the Purchase Agreement.

     NOW, THEREFORE, in consideration of the promises and the mutual covenants and agreements herein contained, intending to be legally bound, the parties hereto hereby agree as follows:

     1. Capitalized Terms.

          (a) The following capitalized terms shall have the respective meanings ascribed thereto below:

     “New Shares” shall mean any shares of the Company that Shareholder purchases or with respect to which Shareholder otherwise acquires beneficial ownership after the date of this Agreement and prior to the Expiration Date, including, without limitation, any shares issued or issuable upon the conversion, exercise or exchange, as the case may be, of any shares held by Shareholder which are convertible into, or exercisable or exchangeable for, capital stock of the Company. New Shares shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares.

     “Person” shall mean any individual, corporation, limited liability company, partnership or other entity, or governmental authority.

     “Shares” shall mean all capital stock of the Company (including all options, warrants and other rights to acquire shares) beneficially owned by Shareholder as of the date of this Agreement.

     “Transfer.” A Person shall be deemed to have effected a “Transfer” of a security if such Person directly or indirectly: (i) sells, pledges, encumbers, grants an option with respect to, transfers or disposes of such security or any interest in such security; or (ii) enters into an agreement or commitment providing for the sale of, pledge of, encumbrance of, grant of an option with respect to, transfer of or disposition of such security or any interest therein.

          (b) Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Purchase Agreement (as defined above).

     2. Restrictions on Transfer of Shares.

          (a) Transfer of Shares. During the period from the date of this Agreement through the Expiration Date, Shareholder shall not cause or permit, directly or indirectly, any Transfer of any of the Shares or New Shares to be effected; provided, however, that notwithstanding the foregoing, Shareholder may transfer Shares to a third party if the transferee shall have agreed in writing to hold such Shares and New Shares (or interest in such Shares or New Shares) subject to, and agree to abide by, all of the terms and conditions of this Agreement.

          (b) Transfer of Voting Rights. During the period from the date of this Agreement through the Expiration Date, Shareholder shall not (i) deposit (or permit the deposit of) any Shares or New Shares in a voting trust or (ii) grant any proxy or power of attorney or enter into any voting agreement or similar agreement in contravention of the obligations of Shareholder under this Agreement with respect to any of the Shares or New Shares.

Through the Expiration Date, Shareholder hereby constitutes and appoints Mimix, or any nominee designated by Mimix, with the full power of substitution at any time during the term of this Agreement, as Shareholder’s true and lawful attorney and proxy (“Proxy”), for and in its name, place, and stead, in the Proxy’s discretion, to demand that the Secretary of the Company call a special meeting of the shareholders of the Company for the purpose of considering any matter referred to in Article 2 of the Purchase Agreement and to vote each Share held by Shareholder, as Shareholder’s Proxy in respect of any such matter, at every annual, adjourned or postponed meeting of the shareholders or the Company, including, without limitation, the right to sign its name as Shareholder (or to direct the recordowner to sign its name as Shareholder) to any consent, certificate, or other document relating to the Company that the state of California might permit or require. THE FOREGOING PROXY AND POWER OF ATTORNEY ARE IRREVOCABLE AND COUPLED WITH AN INTEREST THROUGHOUT THE TERM OF THIS AGREEMENT.

During the period from the date of this Agreement through the Expiration Date, at every meeting of the Shareholders of the Company called, and at every adjournment or postponement thereof, and on every action or approval by written consent of the Shareholders of the Company, Shareholder (in his, her or its capacity as such) shall cause the Shares and any New Shares to be voted (a) in favor of approval of the Purchase Agreement and the Transactions; and (b) unless the Purchase Agreement has been terminated by Buyer, against any Superior Proposal or against any proposal which would result in a breach of any covenant, representation or warranty or any other agreement of the Company under the Purchase Agreement or could reasonably be expected to result in any breach of the Company’s obligations under the Purchase Agreement.

     5. No Solicitation. Shareholder covenants and agrees that, during the term of this Agreement, it shall not, directly or indirectly, solicit, initiate, knowingly encourage, or take any other action designed to facilitate any inquiries or the making or any proposal from any person (other than from Mimix) relating to any transaction that constitutes a Superior Proposal. Shareholder further covenants and agrees that it shall not participate in any discussions or negotiations (except with Mimix) regarding, or furnish to any person (other than Mimix) any information with respect to, or otherwise cooperate in any way with, or assist or participate in or facilitate or encourage, any effort or attempt by any person (other than Mimix) to make or effect any transaction that may constitute a Superior Proposal.
