Capitalized terms used and not otherwise defined herein shall have the respective meanings assigned to them in the Merger Agreement referred to below.

WHEREAS, as of the date hereof, the Stockholders collectively own of record and beneficially shares of capital stock of the Company, as set forth on Schedule I hereto (such shares, or any other voting or equity of securities of the Company hereafter acquired by any Stockholder prior to the termination of this Agreement, being referred to herein collectively as the “Shares”);

WHEREAS, concurrently with the execution of this Agreement, the Buyer and the Company are entering into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), pursuant to which, upon the terms and subject to the conditions thereof, a subsidiary of the Buyer will be merged with and into the Company, and the Company will be the surviving corporation (the “Merger”); and

WHEREAS, as a condition to the willingness of the Buyer to enter into the Merger Agreement, the Buyer has required that the Stockholders agree, and in order to induce the Buyer to enter into the Merger Agreement, the Stockholders are willing to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereby agree, severally and not jointly, as follows:

Section 1. Voting of Shares.

(a) Each Stockholder covenants and agrees that until the termination of this Agreement in accordance with the terms hereof, at any meeting of the stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, such Stockholder will vote, or cause to be voted, all of his, her or its respective Shares (i) in favor of adoption of the Merger Agreement and approval of the Merger contemplated by the Merger Agreement, as the Merger Agreement may be modified or amended from time to time in a manner not adverse to the Stockholders, (ii) against any merger agreement or merger (other than the Merger Agreement and the Merger), consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by the Company or any other proposal, offer or agreement concerning any merger, reorganization, consolidation, recapitalization, business combination, liquidation, share exchange, sale of stock, sale of material assets or similar business transaction involving the Company, any subsidiary of the Company or any division of the Company (each, an “Alternative Proposal”) and (iii) against any other action, agreement or transaction submitted for the vote or written consent of Stockholders that would reasonably be expected to impede, interfere with, delay, postpone, discourage,

frustrate the purposes of or adversely affect the Merger or the other transactions contemplated by the Merger Agreement or this Agreement or the performance by the Company of its obligations under the Merger Agreement or by such Stockholder of its obligations under this Agreement.

(b) Each Stockholder hereby irrevocably grants to, and appoints, the Buyer, and any individual designated in writing by it, and each of them individually, as its proxy and attorney-in-fact (with full power of substitution), for and in its name, place and stead, to vote his, her or its Shares at any meeting of the stockholders of the Company called with respect to any of the matters specified in, and in accordance and consistent with this Section 1. Each Stockholder understands and acknowledges that the Buyer is entering into the Merger Agreement in reliance upon the Stockholder’s execution and delivery of this Agreement. Each Stockholder hereby affirms that the irrevocable proxy set forth in this Section 1(b) is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement. Except as otherwise provided for herein, each Stockholder hereby (i) affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked, (ii) ratifies and confirms all that the proxies appointed hereunder may lawfully do or cause to be done by virtue hereof and (iii) affirms that such irrevocable proxy is executed and intended to be irrevocable in accordance with the provisions of Section 212(e) of the Delaware General Corporation Law. Notwithstanding any other provisions of this Agreement, the irrevocable proxy granted hereunder shall automatically terminate upon the termination of this Agreement.

(c) Each Stockholder covenants and agrees that until the termination of this Agreement in accordance with the terms hereof, at any meeting of the stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, such Stockholder shall appear at each such meeting or otherwise cause the Shares as to which such Stockholder controls the right to vote to be counted as present thereat for purposes of calculating a quorum.

(d) The obligations of each Stockholder specified in this Section 1 shall, subject to Section 6 hereto, apply whether or not the Merger or any action described above is recommended by the Board of Directors of the Company.

Section 2. Transfer of Shares. Each Stockholder covenants and agrees that such Stockholder will not directly or indirectly (i) sell, assign, transfer (including by merger, testamentary disposition, interspousal disposition pursuant to a domestic relations proceeding or otherwise by operation of law), pledge, encumber or otherwise dispose of any of the Shares, (ii) deposit any of the Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Shares or grant any proxy or power of attorney with respect thereto which is inconsistent with this Agreement or (iii) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer (including by merger, testamentary disposition, interspousal disposition pursuant to a domestic relations proceeding or otherwise by operation of law) or other disposition of any Shares.

This Agreement has been duly and validly executed and delivered by the Stockholder and constitutes a valid and binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms.

(c) No Conflicts. The execution and delivery of this Agreement do not, and the consummation of the transactions contemplated hereby will not, conflict with or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation or to loss of a material benefit under, any provision of any loan or credit agreement, note, bond, mortgage, indenture, lease, or other agreement, instrument, permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to the Stockholder, the Shares or any of the Stockholder’s properties or assets. Except as expressly contemplated hereby, the Stockholder is not a party to, and the Shares are not subject to or bound in any manner by, any contract or agreement relating to the Shares, including without limitation, any voting agreement, option agreement, purchase agreement, stockholders’ agreement, partnership agreement or voting trust. Except for filings with the SEC, no consent, approval, order or authorization of, or registration, declaration or filing with, any court, administrative agency or commission or other governmental authority or instrumentality, domestic, foreign or supranational, is required by or with respect to the Stockholder in connection with the execution and delivery of this Agreement or the consummation by the Stockholder of the transactions contemplated hereby.

Section 4. No Solicitation. Prior to the termination of this Agreement in accordance with its terms, each Stockholder agrees, in its individual capacity as a stockholder of the Company, that (i) it will not, nor will it authorize or permit any of its employees, agents and representatives to, directly or indirectly, (a) initiate, solicit or encourage any inquiries or the making of any Alternative Proposal, (b) enter into any agreement with respect to any Alternative Proposal, or (c) participate in any discussions or negotiations regarding, or furnish to any person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or may reasonably be expected to lead to, any Alternative Proposal, and (ii) it will notify the Buyer as soon as possible if any such inquiries or proposals are received by, any information or documents is requested from, or any negotiations or discussions are sought to be initiated or continued with, it or any of its affiliates in its individual capacity. Notwithstanding this Section 4 or any other provision of this Agreement, nothing herein shall be deemed to prohibit, restrict, curtail or otherwise limit any action a Stockholder may take as a member of the Company Board consistent with Section 6.1(a) of the Merger Agreement.

Stock Dividends, etc. In the event of a stock split, stock dividend or distribution, or any change in the common stock by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, exchange of shares or the like, the term “Shares” shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of such shares may be changed or exchanged or which are received in such transaction; provided, that the foregoing shall not prevent the conversion of any of the Shares into the right to receive Merger Consideration (as defined in the Merger Agreement) pursuant to the Merger in accordance with the terms of the Merger Agreement.

Section 6. Termination. This Agreement shall terminate upon the earlier to occur of (i) the Effective Time or (ii) any termination of the Merger Agreement in accordance with the terms thereof; provided, that no such termination shall relieve any party of liability for a willful breach hereof prior to termination.
