- 1 -

through the Expiration Date (including by way of stock dividend or distribution, split-up, recapitalization, combination, exchange of shares and the like).

(d) A Person shall be deemed to have effected a “Transfer” of a Share if such person, directly or indirectly (i) sells, tenders, pledges, encumbers, assigns, grants an option with respect to, establishes an open “put equivalent position” (within the meaning of Rule 16a-h under the Exchange Act) with respect to, transfers or disposes of such Share or any interest in such Share (including the economic consequences of ownership of such Share), or (ii) enters into an agreement or commitment providing for the sale of, tender of, pledge of, encumbrance of, assignment of, grant of an option with respect to, establishment of an open “put equivalent position” with respect to, transfer, or disposition of such Share or any interest therein (including the economic consequences of ownership of such Share).

2. Transfer of Shares. Prior to the termination of this Agreement, Shareholder agrees not to, directly or indirectly:

(b) grant any proxy or power of attorney, deposit any of the Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Shares except as provided in this Agreement.

Notwithstanding anything to the contrary in this Agreement, any Shares Transferred in a manner permitted by Section 2(a) hereof shall be Transferred free and clear of any voting or other restrictions contained herein and of the Proxy (as defined below), in each case except to the extent specifically provided by Section 2(a)(iii).

3. Agreement to Vote Shares.

(a) At every meeting of the stockholders of the Company called, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of Company, the Shareholder (in the Shareholder’s capacity as such), to the extent not voted by the Person(s) appointed under the Proxy (as defined below), shall, or shall cause the holder of record on any applicable record date to, vote the Shares:

(i) in favor of the adoption of the Merger Agreement, and in favor of each of the other actions contemplated by the Merger Agreement;

(ii) against approval of any Company Acquisition Proposal; and

- 2 -

(iii) against any action that is intended, or could reasonably be expected to, materially, impede, interfere with, delay, or postpone the Merger.

(b) In the event that a meeting of the stockholders of the Company is held, the Shareholder shall, or shall cause the holder of record on any applicable record date to, appear at such meeting or otherwise cause the Shares to be counted as present thereat for purposes of establishing a quorum.

(c) The Shareholder shall not enter into any agreement or understanding with any Person to vote or give instructions in any manner inconsistent with the terms of this Section 3.

(d) In the event the Shareholder does not vote its Shares in accordance with this Section 3, Parent shall have the right to vote such Shares in accordance with the terms of the Proxy.

(e) In the event the Board of Directors of the Company effects a Recommendation Withdrawal not in connection with a Superior Proposal, the provisions of Section 3(i) shall be suspended; provided, that in the event the Board of Directors of the Company reinstates its recommendation of the Merger and the Merger Agreement, as the same may be amended, supplemented or modified, thereafter makes a Recommendation Withdrawal in one or more of the circumstances permitted under the Agreement or which would entitle Parent to payment of a termination fee or a court of competent jurisdiction rules that such Recommendation Withdrawal not in connection with a Superior Proposal constituted a breach of the Agreement entiling the Parent to a remedy, the provisions of Section 3(i) shall be reinstated, subject, in all respects to the other terms and conditions of this Agreement.

4. Directors and Officers. Notwithstanding any provision of this Agreement to the contrary, nothing in this Agreement shall (or require the Shareholder to attempt to) limit or restrict any designee of the Shareholder or a Shareholder who is a director or officer of the Company from acting in such capacity or voting, in his capacity as a director of the Company, with Shareholders’ sole discretion on any matter (it being understood that this Agreement shall apply to the Shareholder solely in the Shareholder’s capacity as a shareholder of the Company).

5. Irrevocable Proxy. Concurrently with the execution of this Agreement, the Shareholder shall deliver to Parent a proxy in the form attached hereto as Exhibit A (the “Proxy”), which shall be effective solely as described in Section 3(d) above and irrevocable to the fullest extent permissible by law, with respect to the Shares. Notwithstanding the foregoing, the Proxy shall terminate and be revoked (or shall under no circumstances become effective) with respect to the Shares concurrently with (a) the Transfer of Shares in accordance with Section 2(a) above or (b) upon the Expiration Date, without any notice or action by Shareholder, the transferee or any other person.

6. Representations and Warranties of the Shareholder.

contemplated hereby. This Agreement has been duly executed and delivered by the Shareholder, and, assuming this Agreement constitutes a valid and binding obligation of Parent, constitutes a valid and binding obligation of the Shareholder, enforceable against the Shareholder in accordance with its terms.

(b) No Conflicts. No filing with, and no permit, authorization, consent, or approval of, any state or federal public body or authority (“Governmental Entity”) is necessary for the execution by the Shareholder of this Agreement, the performance by the Shareholder of its obligations hereunder and the consummation by the Shareholder of the transactions contemplated hereby. None of the execution and delivery by the Shareholder of this Agreement, the performance by the Shareholder of its obligations hereunder or the consummation by the Shareholder of the transactions contemplated hereby will (i) conflict with or result in any breach of any agreements or documents entered into by or binding on the Shareholder, (ii) violate any order, writ, injunction, decree, judgment, order, statute, rule, or regulation applicable to the Shareholder, except where such violations, breaches or defaults would not individually or in the aggregate, materially impair the ability of Stockholder to perform this Agreement.

(c) Ownership of Shares. The Shareholder (i) is the beneficial owner of the shares of Company Common Stock indicated on the signature page of this Agreement, (ii) is the owner of options that are exercisable for the number of shares of Company Common Stock indicated on the signature page of this Agreement, all of which options and shares of Company Common Stock issuable upon the exercise of such options are, or the Company Common Stock received upon exercise of an option after the date hereof will be, free and clear of any Liens (except any Liens arising under securities laws or arising hereunder); and (iii) does not own, beneficially or otherwise, any securities of the Company other than the shares of Company Common Stock or options to purchase shares of Company Common Stock, and shares of Company Common Stock issuable upon the exercise of such options, indicated on the signature page of this Agreement.

Except as permitted by this Agreement, the Shares are now and, at all times during the term hereof, or will be, as the case may be, held by Shareholder, or by a nominee or custodian for the benefit of Shareholder, free and clear of all Liens except for any such Liens arising hereunder or under applicable federal and state securities laws, other than Liens that would not individually or in the aggregate, materially impair the ability of Stockholder to perform this Agreement.

(e) No Action. The Shareholder agrees that it will not bring, commence, institute, maintain, or prosecute any action, claim, suit or cause of action, in law or in equity, in any court or before any Governmental Entity, which (i) challenges the validity of or seeks to enjoin the operation of any provision of this Agreement or (ii) alleges that the execution and delivery of this Agreement by the Shareholder, either alone or together with the other Voting Agreements and proxies to be delivered in connection with the execution of the Merger Agreement, or the approval of the Merger Agreement by the board of directors of the Company, breaches any fiduciary duty of the board of directors of the Company or any member thereof.

7. Disclosure. The Shareholder shall permit Parent to publish and disclose in all documents and schedules filed with the Securities and Exchange Commission, and any press

- 4 -

release or other disclosure document that Parent determines to be necessary or desirable in connection with the Merger and any transactions related to the Merger, the Shareholder’s identity and ownership of Shares and the nature of the Shareholder’s commitments, arrangements and understandings under this Agreement.

8. Further Assurances. Subject to the terms and conditions of this Agreement, the Shareholder shall use reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things reasonably necessary to fulfill such Shareholder’s obligations under this Agreement.

9. Legending of Shares. If so requested by Parent, the Shareholder agrees that the Shares shall bear a legend stating that they are subject to this Agreement and the Proxy.

10. Termination. This Agreement and the Proxy shall terminate and shall have no further force or effect as of the Expiration Date.

11. Appraisal Rights. The Shareholder irrevocably waives and agrees not to exercise any rights (including, without limitation, under Section 262 of the General Corporation Law of the State of Delaware) to demand appraisal of any of the Shares which may arise with respect to the Merger.

12. Miscellaneous.

(a) Validity. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of the other provisions of this Agreement, which will remain in full force and effect. In the event any Governmental Entity of competent jurisdiction holds any provision of this Agreement to be null, void or unenforceable, the parties hereto shall negotiate in good faith and execute and deliver an amendment to this Agreement in order, as nearly as possible, to effectuate, to the extent permitted by law, the intent of the parties hereto with respect to such provision.

(b) Binding Effect and Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations of the parties hereto may be assigned by either of the parties without prior written consent of the other; provided, that Parent may assign any of their rights and obligations hereunder, in whole or in part, to any Affiliate or Subsidiary of Parent without obtaining the consent of the Shareholder.

(c) Amendments; Waiver. This Agreement may be amended by the parties hereto, and the terms and conditions hereof may be waived, only by an instrument in writing signed on behalf of each of the parties hereto, or, in the case of a waiver, by an instrument signed on behalf of the party waiving compliance.

(d) Specific Performance; Injunctive Relief. The parties hereto acknowledge that Parent shall be irreparably harmed and that there shall be no adequate remedy at law for a

violation of any of the covenants or agreements of the Shareholder set forth herein.
