1. Voting; Proxies; Etc.

(a) Agreement to Vote. The Stockholder hereby agrees that, from and after the date hereof and until this Agreement shall have been terminated in accordance with Section 7:

of the stockholders of the Company or in any other circumstances in which the Stockholder is entitled to vote, consent or give any other approval with respect to the Merger and adoption of the Merger Agreement, the Stockholder shall vote (or cause to be voted) the Shares (to the extent such Shares are entitled to be voted and are not so voted pursuant to the proxy granted in Section 1(b)) in favor of adoption of the Merger Agreement and the approval of the terms thereof and each of the other actions contemplated by the Merger Agreement and this Agreement.

(ii) At any meeting of the stockholders of the Company, however called, or at any adjournment thereof, or in connection with any written consent of the stockholders of the Company, or in any other circumstances in which the Stockholder is entitled to vote, consent or give any other approval, the Stockholder shall vote (or cause to be voted) the Shares (to the extent the Shares are entitled to be voted) against the following actions:

(1) any proposal that would result in a breach by the Company of the Merger Agreement or by the Stockholder hereunder; or

(2) any action or agreement that is intended to, or would be reasonably likely to, impede, interfere with, delay, postpone or attempt to discourage the Merger, including, but not limited to: (A) the adoption or approval by the Company of any Acquisition Proposal; (B) any amendment of the Company’s certificate of incorporation or by-laws; (C) any material change in the present capitalization or dividend policy of the Company; or (D) any other material change in the Company’s corporate structure or business.

(b) Proxies. As security for the agreements of the Stockholder provided for herein, the Stockholder hereby grants to the Transitory Sub a proxy for the term of this Agreement to vote the Shares as indicated in Section 1(a) above.

(c) Transfer Restrictions. The Stockholder agrees not to (i) sell, transfer, pledge, encumber, assign or otherwise dispose of or hypothecate (including by gift or by contribution or distribution to any trust or similar instrument (collectively, “Transfer”)), or enter into any contract, option or other arrangement or understanding (including any profit sharing arrangement) with respect to the Transfer of, any of the Shares other than pursuant to the terms hereof and the Merger Agreement, (ii) enter into any voting arrangement or understanding with respect to the Shares (other than this Agreement), whether by proxy, voting agreement or otherwise, or (iii) take any action that could make any of its representations or warranties contained herein untrue or incorrect in any material respect or would have the effect of preventing or disabling the Stockholder from performing any of its obligations hereunder.

Nothing in this Section shall restrict the activities of any Stockholder in his or her capacity as a director of officer of the Company.

2. Option.

(a) The Stockholder hereby grants to the Transitory Sub an irrevocable option to purchase the Shares on the terms and subject to the conditions set forth herein (the “Option”).

(b) The Option may be exercised by the Transitory Sub, as a whole and not in part, at any time during the period commencing upon (x) the termination of the Merger Agreement pursuant to Section 8.1(e) thereof and (y) ending 96 hours after such termination.

(c) If the Transitory Sub wishes to exercise the Option, the Transitory Sub shall send a written notice to the Stockholder of its intention to exercise the Option, specifying the place, and, if then known, the time and the date (the “Option Closing Date”) of the closing (the “Option Closing”) of the purchase. The Option Closing Date shall occur on the fifth business day (or such longer period as may be required by applicable Governmental Regulations) after the later of (i) the date on which such notice is delivered and (ii) the satisfaction of the conditions set forth in Section 2(f).

(d) At the Option Closing, the Stockholder shall deliver to the Transitory Sub (or its designee) all of the Shares by delivery of a certificate or certificates evidencing the Shares, duly endorsed to the Transitory Sub or accompanied by stock powers duly executed in favor of the Transitory Sub, with all necessary stock transfer stamps affixed.

(e) At the Option Closing, the Transitory Sub shall deliver, and the Buyer shall cause the Transitory Sub to deliver to the Stockholder in respect of the Shares the purchase price per Share, as defined in the next sentence. The purchase price per Share shall be, in respect of each share of Company Common Stock purchased pursuant to the Option, $1.83 per share (the “Purchase Price”).

- 3 -

(f) The Option Closing shall be subject to the satisfaction of (or, in the case of subparagraph (iii), the waiver by the Transitory Sub of) each of the following conditions:

(i) no Governmental Entity of competent jurisdiction shall have enacted, issued, promulgated, enforced or entered any order, executive order, stay, decree, judgment or injunction (preliminary or permanent) or statute, rule or regulation which is in effect and which has the effect of making the consummation of the purchase and sale of the Shares pursuant to the exercise of the Option illegal or otherwise prohibiting consummation of the purchase and sale of the Shares pursuant to the exercise of the Option; and

(ii) any waiting period applicable to the consummation of the purchase and sale of the Shares pursuant to the exercise of the Option under any applicable Antitrust Laws or other Government Regulations shall have expired or been terminated.

If the Option Closing shall not occur within 90 days after the exercise of the Option then, unless such failure results from the Stockholder’s failure to comply with this Agreement, the Option and this Agreement shall terminate and be of no further force or effect.

(g) If, after purchasing the Shares pursuant to the Option, (x) the Transitory Sub or any of its affiliates has not acquired, or consummated a tender or exchange offer for, the remaining Company Common Stock or consummated a merger or consolidation with the Company and (y) the Transitory Sub or any of its affiliates receives any cash or non-cash consideration in respect of some or all of the Shares (the “Transferred Shares”) in connection with (or during the pendency of) a Third Party Business Combination (as defined below) during the period commencing on the date of the Option Closing and ending on the six month anniversary thereof, the Transitory Sub shall promptly pay to the Stockholder, in cash as an addition to the aggregate Purchase Price for all Shares, 33% of the excess, if any, of the value of such consideration received over the aggregate Purchase Price paid for the Transferred Shares; provided that, (i) with respect to any of the consideration received by the Transitory Sub or such affiliates for the Transferred Shares consisting of securities listed on a national securities exchange or traded on the Nasdaq National Market, the per share value of such consideration shall be equal to the closing price per share of such securities listed on such national securities exchange or the Nasdaq National Market on the date such transaction is consummated, and (ii) with respect to any consideration received by the Transitory Sub or such affiliates for the Transferred Shares in a form other than securities so listed, the per share value shall be determined in good faith as of the date such transaction is consummated by the Transitory Sub and the Stockholder, or, if the Transitory Sub and the Stockholder cannot reach agreement, by a nationally recognized investment banking firm reasonably acceptable to the parties. The term “Third Party Business Combination” means the occurrence of any of the following events: (A) the Company, or more than 50% of the outstanding shares of the Company Common Stock, is acquired by merger or otherwise by any Person other than the Buyer, the Transitory Sub or their respective affiliates (a “Third Party”); or (B) a Third Party acquires all or substantially all of the assets of the Company and its subsidiaries, taken as a whole; provided, however, that in no event will any transaction in which shares of the Company Common Stock or any of its assets are sold or transferred directly or indirectly in connection with or as a part of a sale or other transaction involving a sale, merger or other similar transaction of the Buyer or any of its material assets or business constitute a Third Party Business Combination, and in no event will a sale of any division, line of business or similar unit of the Company and its subsidiaries (other than a sale of all or substantially all of the assets of the Company and its subsidiaries) constitute a Third Party Business Combination.

- 4 -

(h) (i) In the event that the Merger Agreement shall have been terminated under circumstances in which the Buyer is or may become entitled to receive a payment pursuant to Section 8.3(c) thereof, the Stockholder shall pay to the Buyer on demand an amount equal to 67% of the Profit (determined in accordance with Section 3(h)(ii)) of the Stockholder, if any, from the consummation of any Third Party Business Combination for which a definitive agreement is entered into within six months of such termination.

(ii) For purposes of this Section 2(h), the “Profit” of the Stockholder from any Third Party Business Combination shall equal (A) the aggregate consideration received by the Stockholder pursuant to such Third Party Business Combination in respect of the Stockholder’s Shares plus (B) the fair market value, on the date of disposition, of all Shares disposed of after the termination of the Merger Agreement and prior to the date of such consummation, less (C) the sum of the fair market value of the aggregate consideration that would have been issuable or payable to the Stockholder if the Stockholder had received the Merger Consideration pursuant to the Merger Agreement as originally executed for each of the Shares. For purposes of calculating the price per share paid in such transaction with respect to (i) any such consideration consisting of securities listed on a national securities exchange or traded on the Nasdaq National Market, the per share value of such consideration shall be equal to the closing price per share of such securities listed on such national securities exchange or the Nasdaq National Market on the date such transaction is consummated, and (ii) any consideration other than securities so listed, the per share value shall be determined in good faith by the Transitory Sub and the Stockholders as of the date such transaction is consummated, or, if the Transitory Sub and the Stockholders cannot reach agreement, by a nationally recognized investment banking firm reasonably acceptable to the parties.

(i) If, after the date hereof, the shares of Company Common Stock are combined into a smaller number of shares or split or subdivided into a greater number of shares, the determinations in this Section 2 shall be proportionately adjusted so that the economic consequences of the transactions contemplated hereby are not affected by such action.

14. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party.

All rights, powers and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise of any thereof by any party shall not preclude the simultaneous or later exercise of any other such right, power or remedy by such party.

(b) EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING IN RELATION TO THIS AGREEMENT AND FOR ANY COUNTERCLAIM THEREIN.

(c) The parties acknowledge and agree that the Buyer, the Transitory Sub and the Stockholder would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any breach of this Agreement could not be adequately compensated in all cases by monetary damages alone. Accordingly, in addition to any other right or remedy to which the Buyer, the Transitory Sub or the Stockholder may be entitled, at law or in equity, it shall be entitled to enforce any provision of this Agreement by a decree of specific performance and temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.
