WHEREAS, as of the date hereof, each Stockholder is the record and beneficial owner of the number of shares of Common Stock set forth on Exhibit A hereto (together with such additional shares of Common Stock that become beneficially owned (within the meaning of Rule 13d-3 promulgated under the Securities Exchange Act of 1934, as amended) by such Stockholder, whether by purchase, stock dividend, distribution, split-up, recapitalization, combination, exchange of shares or the like, or upon the exercise of options, conversion of convertible securities or otherwise, after the date hereof, the “Owned Shares”).

WHEREAS, as a condition to Parent’s willingness to enter into and perform its obligations under the Merger Agreement, Parent has required that each Stockholder agree, and each Stockholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration given to each party hereto, the receipt of which is hereby acknowledged, the parties agree as follows:

Each Stockholder hereby agrees that, from the date of execution and public announcement of the Merger Agreement until the earliest of (i) the time that the Company Stockholder Approval has been obtained, (ii) termination of this Agreement in accordance with Section 6.1 and (iii) such time as the Board of Directors of the Company withdraws (or qualifies or modifies in a manner adverse to Parent) the Recommendation solely in

respect of an Intervening Event (the “Voting Period”), at any meeting of the stockholders of the Company at which the approval and adoption of the Merger Agreement and the transactions contemplated thereby is to be voted upon, however called, or any adjournment or postponement thereof, or in connection with any written consent of the stockholders of the Company, such Stockholder shall be present (in person or by proxy, or cause to be present) and vote (or cause to be voted), or give written consent (or cause written consent to be given), in each case to the extent entitled to vote thereon, all of its Owned Shares at such time (a) in favor of approval and adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger and (b) against (A) any Alternative Proposal or any other action, proposal, agreement or transaction made in opposition to or competition with the Merger or the Merger Agreement, and (B) any other action, proposal, agreement or transaction that would reasonably be expected, or the effect of which would reasonably be expected, to prevent, nullify, materially impede, interfere with, frustrate, delay, postpone, discourage or adversely affect the timely consummation of Merger or the other transactions contemplated by the Merger Agreement or the performance by the Stockholder of its obligations under this Agreement, including (1) any extraordinary dividend or distribution by the Company, (2) any material change in the capital structure of the Company or any Subsidiary of the Company, (3) any merger agreement or merger (other than the Merger Agreement), consolidation, combination, material business transaction, sale of assets, reorganization, recapitalization, dissolution, liquidation or winding up of the Company, or any other action or transaction involving the Company, and (4) any amendment of the Company’s organizational documents. Notwithstanding anything herein to the contrary, this Section 1.1 shall not require any Stockholder to be present (in person or by proxy) or vote (or cause to be voted) any of its Owned Shares to amend the Merger Agreement or take any action that could result in the amendment or modification, or a waiver of a provision therein, in any such case, in a manner that (i) decreases the amount or changes the form of the Merger Consideration, (ii) imposes any material restrictions on or additional conditions on the payment of the Merger Consideration to stockholders or (iii) extends the End Date.

1.2 Other Voting Rights. Except as permitted by this Agreement, each Stockholder will continue to hold and shall have the right to exercise all voting rights related to such Stockholder’s Owned Shares.

2. Representations and Warranties of Stockholders. Each Stockholder hereby represents and warrants to Parent and the Company, as of the date of this Agreement and as of the Company Meeting, as follows:

2.1 Power; Due Authorization; Binding Agreement. Such Stockholder has the requisite power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby.

This Agreement has been duly and validly executed and delivered by such Stockholder and, assuming the due and valid authorization, execution and delivery hereof by the other parties hereto, constitutes a valid and binding agreement of such Stockholder, enforceable against such Stockholder in accordance with its terms, except that (i) such enforcement may be subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar Laws, now or hereafter in effect, relating to creditors’ rights generally and (ii) equitable remedies of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding therefor may be brought.

Other than restrictions in favor of Parent pursuant to this Agreement and except for such transfer restrictions of general applicability as may be provided under the Securities Act of 1933, as amended, or the “blue sky” Laws of the various states of the United States, or as disclosed by such Stockholder on a Schedule 13D filed with respect to the Company, as of the date hereof such Stockholder has, and at any stockholder meeting of the Company held during the Voting Period to vote regarding approval and adoption of the Merger Agreement, such Stockholder will have (except as otherwise permitted by this Agreement), sole voting power and sole dispositive power with respect to the matters set forth in Section 1.1 in respect of all of the then Owned Shares of such Stockholder.

3

Agreement will not, (i) conflict with or violate any Law applicable to such Stockholder or by which any of its assets or properties is bound or (ii) conflict with, result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or require payment under, or result in the creation of any Lien on the properties or assets of such Stockholder pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which the Stockholder is a party or by which such Stockholder or any of its assets or properties (including any Owned Shares) is bound, except for any of the foregoing as could not reasonably be expected, either individually or in the aggregate, to materially impair the ability of such Stockholder to perform fully its obligations hereunder on a timely basis.
