1.2. Transfer of Subject Shares; No Inconsistent Arrangements. Except as provided hereunder or under the Merger Agreement, such Stockholder shall not, directly or indirectly, (a) create any Lien other than restrictions imposed by applicable Law or pursuant to this Agreement on any Subject Shares, (b) transfer, sell, assign, gift or otherwise dispose of (by operation of law (including by merger) or otherwise), either voluntarily or involuntarily, any Subject Shares, beneficial ownership thereof or any other interest therein (collectively, “Transfer”), or enter into any contract, option or other understanding or arrangement with respect to any Transfer of the Subject Shares, beneficial ownership thereof or any interest therein, (c) enter into any swap, hedge, derivative or other arrangement that Transfers to another, in whole or in part, any of the economic consequences of ownership of the Subject Shares, whether settled by delivery of Subject Shares, other securities, in cash or otherwise, (d) grant or permit the grant of any proxy, power of attorney or other authorization in or with respect to the Subject Shares, (e) deposit or permit the deposit of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Subject Shares, (f) enter into any agreement with any Person, or take any other action, that violates or conflicts with such Stockholder’s representations, warranties, covenants and obligations under this Agreement or (g) take any action that would restrict or otherwise affect such Stockholder’s legal power, authority and right or its ability to comply with and perform its covenants and obligations under this Agreement. For purposes of this Agreement, the term “Transfer” shall include the transfer (including by way of sale, disposition, operation of law (including by merger) or any other means) of a controlled Affiliate of such Stockholder or such Stockholder’s interest in a controlled Affiliate which is the record holder of any Subject Shares.

Such Stockholder shall permit and hereby authorizes Parent to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that Parent reasonably determines to be necessary in connection with the Merger and any transactions contemplated by the Merger Agreement, such Stockholder’s identity and ownership of the Subject Shares and the nature of such Stockholder’s commitments and obligations under this Agreement; provided, that the Company shall give each such stockholder and its, her or his legal counsel a reasonable opportunity to review and comment on such publications or disclosures prior to being made public.

1.5. Irrevocable Proxy. Such Stockholder hereby revokes (or prior hereto has caused to be revoked) any proxies that such Stockholder has heretofore granted with respect to the Subject Shares. Such Stockholder hereby irrevocably (to the fullest extent permitted by law) appoints Parent, acting through any of its authorized signatories, as the sole and exclusive attorney-in-fact and proxy for and on behalf of such Stockholder, with full power of substitution and resubstitution, for and in the name, place and stead of such Stockholder, to: (a) attend any and all meetings of the Company Stockholders, (b) vote, express consent or dissent or issue instructions to the record holder to vote such Stockholder’s Subject Shares in accordance with the provisions of Section 1.1 at any and all meetings of the Company Stockholders or in connection with any action sought to be taken by written consent of the Company Stockholders without a meeting and (c) grant or withhold, or issue instructions to the record holder to grant or withhold, consistent with the provisions of Section 1.1, all written consents with respect to the Subject Shares in connection with any action sought to be taken by written consent without a meeting.

The proxy set forth in this Section 1.5 is executed and intended to be irrevocable, subject, however, to its automatic termination upon the termination of this Agreement pursuant to Section 4.2. Each Stockholder 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 1.5.

1.6. No Obligation to Exercise Options or Other Securities. Nothing contained in this Agreement shall require any Stockholder (or shall entitle any proxy of such Stockholder) to (a) convert, exercise or exchange any option, warrants or convertible securities in order to obtain any underlying Subject Shares which may be voted or (b) vote, or execute any consent with respect to, any Subject Shares underlying such options, warrants or convertible securities that have not yet been issued as of the applicable record date for that vote or consent.

1.7. No Solicitation. Each Stockholder agrees that it will not, and will not permit its Representatives to, directly or indirectly, take any action that the Company would then be prohibited from taking under Section 5.3 of the Merger Agreement. Such Stockholder shall cease immediately

3

and cause to be terminated all activities, discussions and negotiations that commenced prior to the date of this Agreement regarding any proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal.
