WHEREAS, concurrently herewith, the Buyer, Merger Sub and the Company are entering into an Agreement and Plan of Merger (the “Merger Agreement”) that provides for, among other things, (i) the merger of Merger Sub with and into the Company (the “Merger”) and (ii) the conversion of each Company Share issued and outstanding immediately prior to the Effective Time (other than certain specified shares) into the right to receive the Merger Consideration;

WHEREAS, as of the date hereof, each of the Stockholders owns of record the Common Shares and the Class A Shares set forth opposite such Stockholder’s name on Schedule A hereto (such Common Shares and Class A Shares, the “Existing Shares”); and

WHEREAS, as a condition and inducement to the Buyer and Merger Sub to enter into the Merger Agreement, the Stockholders are entering into this Agreement.

NOW, THEREFORE, in consideration of the representations and warranties, covenants and agreements contained herein, the parties hereto agree as follows:

1.             Definitions. For purposes of this Agreement:

(a)           Capitalized terms used and not otherwise defined herein have the respective meanings ascribed to them in the Merger Agreement. References to the Merger Agreement herein mean the Merger Agreement as in effect on the date hereof and do not mean or include any amendment or modification to the Merger Agreement.

(b)           In addition to terms defined elsewhere in this Agreement, the following terms have the respective meanings ascribed to them below:

“Term of this Agreement” means the period from and including the date hereof through and including the Termination Date.

“Subject Shares” means the Existing Shares, together with any additional shares that become held of record or owned by any Stockholder in any capacity during the Term of this Agreement, whether upon exercise of options (including Company Stock Options), conversion of convertible securities, purchase, exchange or otherwise; provided, that in the event of a stock dividend or distribution, or any change in the shares by reason of stock dividend or distribution, split-up, recapitalization, combination,

1

exchange of shares or the like, the term “Subject Shares” will be deemed to refer to and include the Subject Shares as well as all such stock dividends and distributions and any securities into which or for which any or all of the Subject Shares may be changed or exchanged or that are received in such transaction.

2.             Agreement to Vote. Each Stockholder hereby irrevocably agrees that, during the Term of this Agreement, at any annual, special or other meeting of the Company’s stockholders (or adjournment or postponement thereof), however called, or in connection with any action by consent of the Company’s stockholders, such Stockholder will vote (or cause to be voted) all of the Subject Shares or execute and deliver a written consent of the Company’s stockholders (or cause such a written consent to be executed and delivered) (a) in favor of adoption and approval of the Merger Agreement and the transactions contemplated thereby, and any actions in furtherance thereof requiring a vote of the Company’s stockholders, (b) against any action, proposal, transaction or agreement that would result in a breach in any material respect of any representation, warranty, covenant or agreement of the Company contained in the Merger Agreement or that is reasonably likely to result in any of the conditions to the Buyer’s or Merger Sub’s obligations under the Merger Agreement not being fulfilled and (c) except as otherwise agreed to in writing in advance by the Buyer, against (i) any Transaction Proposal, (ii) any reorganization, recapitalization, dissolution or liquidation of the Company, (iii) any change to the present capitalization of the Company, any amendment to the Company’s certificate of incorporation or by-laws other than in connection with the transactions contemplated by the Merger Agreement or any other material change to the Company’s corporate structure or business and (iv) any other action or proposal that is intended, or would reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect the transactions contemplated by the Merger Agreement and (d) in favor of any matter reasonably necessary for consummation of the transactions contemplated by the Merger Agreement, and in connection therewith, to execute any documents that are reasonably necessary or appropriate in order to effectuate the foregoing, including granting to the Buyer the ability of the Buyer or its nominees to vote such Subject Shares directly. Any such vote will be cast or consent will be given in accordance with procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording the results of such vote or consent. Each Stockholder agrees that it will not enter into any agreement with any person or entity or give any instructions in any manner during the Term of this Agreement the effect of which would be inconsistent with or violative of this Section 2. Each Stockholder hereby irrevocably waives any appraisal or dissenters’ rights that it may have in connection with the Merger. Notwithstanding anything to the contrary herein, in the event that the vote of the Subject Shares is required in order to effect an amendment to the Merger Agreement, the provisions of this Agreement, including this Section 2, will not apply with respect to any Stockholder’s vote of such Subject Shares.

3.             Grant of Irrevocable Proxy. Each Stockholder hereby appoints the Buyer and any designee of the Buyer, and each of them individually, as such Stockholder’s attorney-in-fact and proxy, with full power of substitution and re-substitution, to vote all of the Subject Shares, or to act by written consent in respect thereof, in accordance with Section 2. This power of attorney and proxy is given to secure the performance of the

2

Stockholders’ obligations under this Agreement. Each Stockholder acknowledges that THIS POWER OF ATTORNEY AND PROXY (a) IS COUPLED WITH AN INTEREST, (b) constitutes, among other things, an inducement for the Buyer and the Merger Sub to enter into the Merger Agreement and (c) IS IRREVOCABLE AND WILL NOT BE TERMINATED UPON THE OCCURRENCE OF ANY EVENT; provided, that this power of attorney and proxy will terminate upon the Termination Date. Each Stockholder hereby ratifies and confirms all that this power of attorney and proxy may lawfully do or cause to be done by virtue hereof. The power of attorney granted by each Stockholder herein is a durable power of attorney and will survive the dissolution, bankruptcy or other incapacity of such Stockholder; and the proxy granted herein by each Stockholder is executed and intended to be irrevocable in accordance with the provisions of Section 212(e) of the Delaware General Corporation Law. Each Stockholder hereby revokes all other powers of attorney and proxies with respect to the Subject Shares that it may have heretofore appointed or granted, and agrees that it will not, during the Term of this Agreement, appoint or grant any subsequent power of attorney or proxy (and if appointed or granted in violation hereof, any such power of attorney or proxy will not be effective). Each Stockholder will promptly cause a fully executed copy of this Agreement to be delivered to the Buyer. Each Stockholder will take such further action or execute such other instruments as may be necessary to effectuate the intent of this Section 3.

4.             Agreement to Retain. Except as contemplated by this Agreement, each Stockholder agrees, during the Term of this Agreement, not to (a) sell, transfer, tender, pledge, hypothecate, encumber, assign or otherwise dispose of, including by gift (collectively, “Transfer”), or enter into any agreement, option or other arrangement with respect to, or consent to, a Transfer of, any or all of the Subject Shares, or any interest in any of the foregoing, except to the Buyer, (b) deposit any of the Subject Shares into a voting trust, enter into any voting agreement or similar agreement or arrangement with respect to any of the Subject Shares, or any interest in any of the foregoing, except to the Buyer or in accordance with this Agreement or (c) take any other action that is intended, or could reasonably be expected, to restrict, limit or interfere with such Stockholder’s ability to perform its obligations under this Agreement or the transactions contemplated hereby. Notwithstanding the foregoing, such Stockholder may Transfer Subject Shares to any Permitted Transferee; provided that such Permitted Transferee executes a joinder to this Agreement in form and substance satisfactory to the Buyer in which such Permitted Transferee agrees to be bound by the terms and provisions of this Agreement. For the purposes of this Section 4, “Permitted Transferee” will mean (i) such Stockholder’s spouse, children, parents or siblings (collectively, “Family Members”), (ii) such Stockholder’s estate, (iii) any trust solely for the benefit of such Stockholder and/or any Family Member(s) and of which such Stockholder and/or such Family Member(s) is the trustee or are the trustees, and (iv) any partnership, corporation or limited liability company which is wholly owned and controlled by such Stockholder and/or such Family Member(s).

5.             No Solicitation of Transactions. Subject to Section 6 hereof, during the Term of this Agreement, without the prior consent of the Buyer, no Stockholder will directly or indirectly, nor in the case of any Stockholder that is a corporation or other

3

entity will it authorize or permit any of its respective directors, officers, employees, counsel, accountants and other agents, advisors and representatives to, directly or indirectly, (i) solicit, initiate or encourage (including by way of furnishing information), or take any other action designed to facilitate, any inquiries, proposals or offers from any Person that constitute, or would reasonably be expected to lead to, a Transaction Proposal, (ii) participate in any discussions or negotiations (including by way of furnishing information) regarding any such inquiry, proposal, offer or Transaction Proposal or (iii) otherwise cooperate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt by any other Person to do or seek any of the foregoing. Each Stockholder will promptly (and no more than one Business Day after receipt) advise the Buyer of the receipt by it of any Transaction Proposal, or any inquiry that would reasonably be expected to lead to a Transaction Proposal or of any request for information in connection with a possible Transaction Proposal, including the material details of any such Transaction Proposal, inquiry or request and the identity of the Person requesting such information or making such Transaction Proposal and, if in writing, provide the Buyer with copies of all correspondence or other written material sent or provided to such Stockholder by any third party in connection with any Transaction Proposal, inquiry or request. Each Stockholder will cease immediately any existing discussions regarding a Transaction Proposal.

6.             Stockholder Capacity; Fiduciary Duties. No Stockholder executing this Agreement who is or becomes during the term hereof a director or officer of the Company or any of its Subsidiaries makes any agreement or understanding herein or is obligated hereunder in his or her capacity as such director or officer. Nothing in this Agreement will limit or restrict any Stockholder or Affiliate or designee of a Stockholder who serves as a member of the Board of Directors of the Company or as an officer of the Company in acting in his or her capacity as a director or officer of the Company and exercising his or her fiduciary duties and responsibilities, it being understood that this Agreement will apply to the Stockholders solely in their respective capacities as stockholders of the Company and will not apply to any such Stockholder’s, Affiliate’s or designee’s actions, judgments or decisions as a director or officer of the Company.
