Pursuant to the Merger, shares of Common Stock of Company will be converted into the right to receive shares of Common Stock of Parent in the manner set forth in the Merger Agreement.

    C.  As a material inducement to enter into the Merger Agreement, Parent desires the Shareholder to agree, and the Shareholder is willing to agree, not to transfer or otherwise dispose of any of the Shares, or any other shares of capital stock of Company acquired hereafter and prior to the Expiration Date (as defined in Section 1.1 below), except as otherwise permitted hereby, and to vote the Shares and any other such shares of capital stock of Company so as to facilitate consummation of the Merger.

    NOW, THEREFORE, in consideration of the covenants, promises and representations set forth herein, the parties agree as follows:

    1.  Agreement to Retain Shares.  

    1.1  Transfer and Encumbrance.  A Shareholder shall be deemed to have effected a "Transfer" of a security if he or she directly or indirectly: (i) sells, makes any short sales of, lends, hypothecates, pledges, encumbers, enters into any type of equity swap or hedging of, 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, making any short sale of, lending of, pledge of, encumbrance of, equity swap or hedging of, grant of an option with respect to, transfer of or disposition of such security or any interest therein; provided, however, that Shareholder may Transfer any or all of the Shares acquired by the Shareholder in connection with purchase period ending June 30, 2001 under the Company's 1996 Employee Stock Purchase Plan (the "ESPP Shares") and up to      of the Shares (as adjusted for splits, dividends and the like), exclusive of the ESPP Shares; provided, further, that any such Transfers shall have occurred no less than 30 days prior to the Effective Time.

    Shareholder agrees not to Transfer (except as may be specifically required by court order or operation of law) the Shares or any New Shares as defined in Section 1.2 below, or to make any offer or agreement relating thereto, at any time prior to the Expiration Date unless each party to which such Shares or New Shares or any interest in any of such Shares or New Shares is or may be transferred shall have (i) executed a counterpart of this Voting Agreement and a proxy in the form attached hereto as Exhibit A and (ii) agreed to hold such Shares or New Shares or interest in such Shares or New Shares subject to all of the terms and

As used herein, the term "Expiration Date" shall mean the earlier to occur of (i) such date and time as the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement and (ii) such date and time as the Merger Agreement shall be terminated in accordance with its terms.

    1.2  Additional Purchases.  Shareholder agrees that any shares of capital stock of Company that Shareholder purchases or with respect to which Shareholder otherwise acquires beneficial ownership (as such term is defined in Rule 13d-3 under the Exchange Act) after the execution of this Agreement and prior to the Expiration Date ("New Shares") shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares.

    2.  Agreement to Vote Shares.  At every meeting of the shareholders of Company called with respect to, and at every adjournment thereof, and on every action or approval by written consent of the shareholders of Company with respect to, approval of the Merger Agreement and the Merger, Shareholder shall vote the Shares and any New Shares in favor of approval of the Merger Agreement and the Merger and any matter that could reasonably be expected to facilitate the Merger. Shareholder agrees not to take any actions contrary to Shareholder's obligations under this Agreement.

    3.  Irrevocable Proxy.  Concurrently with the execution of this Agreement, Shareholder agrees to deliver to Parent a proxy in the form attached hereto as Exhibit A (the "Proxy"), which shall be irrevocable, with respect to the total number of shares of capital stock of Company beneficially owned (as such term is defined in Rule 13d-3 under the Exchange Act) by Shareholder set forth therein.

    4.  Representations, Warranties and Covenants of the Shareholder.  Shareholder hereby represents, warrants and covenants to Parent that Shareholder (i) is the beneficial owner of the Shares, which at the date hereof and at all times up until the Expiration Date will be free and clear of any liens, claims, options, charges or other encumbrances; (ii) does not beneficially own any shares of capital stock of Company other than the Shares (excluding shares as to which Shareholder currently disclaims beneficial ownership in accordance with applicable law); and (iii) has full power and authority to make, enter into and carry out the terms of this Agreement and the Proxy.

    5.  Additional Documents.  Shareholder hereby covenants and agrees to execute and deliver any additional documents necessary or desirable, in the reasonable opinion of Parent and Shareholder, as the case may be, to carry out the intent of this Agreement.
