Subject to the terms of this Agreement, each Stockholder agrees to tender or cause to be tendered in the Offer all of such Stockholder’s Subject Shares (other than Options that are not exercised during the term of this Agreement) pursuant to and in accordance with the terms of the Offer, free and clear of all Encumbrances (as defined below) except for Permitted Encumbrances (as defined below). Without limiting the generality of the foregoing, as promptly as practicable after, but in no event later than ten (10) business days after,

the commencement (within the meaning of Rule 14d-2 under the Exchange Act) of the Offer, each Stockholder shall deliver or cause to be delivered pursuant to the terms of the Offer (a) a letter of transmittal with respect to all of such Stockholder’s Subject Shares complying with the terms of the Offer, (b) a certificate representing all such Subject Shares that are certificated or, in the case of a book-entry share of any uncertificated Subject Shares, written instructions to such Stockholder’s broker, dealer or other nominee that such Subject Shares be tendered, including a reference to this Agreement, and requesting delivery of an “agent’s message” (or such other evidence, if any, of transfer as the Depository Agent may reasonably request), and (c) all other documents or instruments required to be delivered by other Company stockholders pursuant to the terms of the Offer (it being understood that this sentence shall not apply to Options that are not exercised during the term of this Agreement). Each Stockholder agrees that, once any of such Stockholder’s Subject Shares are tendered, such Stockholder will not withdraw or will cause not to be withdrawn such Subject Shares from the Offer, unless and until this Agreement shall have been validly terminated in accordance with Section 5.2. For clarity, Stockholder shall not be required, for purposes of this Agreement, to exercise any unexercised Options held by Stockholder.

1.2 Agreement to Vote. Subject to the terms of this Agreement, each Stockholder hereby irrevocably and unconditionally agrees that, during the time this Agreement is in effect, at any annual or special meeting of the stockholders of the Company, however called, including any adjournment or postponement thereof, and in connection with any action proposed to be taken by written consent of the stockholders of the Company, such Stockholder shall, in each case to the fullest extent that such Stockholder’s Subject Shares are entitled to vote thereon: (a) appear at each such meeting or otherwise cause all such Subject Shares to be counted as present thereat for purposes of determining a quorum; and (b) be present (in person or by proxy) and vote (or cause to be voted), or deliver (or cause to be delivered) a written consent with respect to, all of its Subject Shares (i) against any action or agreement that is intended or would reasonably be expected to (A) result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement, or of any Stockholder contained in this Agreement, or (B) result in any of the conditions set forth in Section VII or Annex I of the Merger Agreement not being satisfied on or before the End Date; (ii) against any change in the Board of Directors of the Company; and (iii) against any Acquisition Proposal and against any other proposed action, agreement or transaction involving the Company that is intended, or would reasonably be expected, to impede, interfere with, delay, postpone, adversely affect or prevent the consummation of the Offer, the Merger or the other Transactions, including (x) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving the Company (other than the Merger); (y) a sale, lease, license or transfer of a material amount of assets (including, for the avoidance of doubt, Intellectual Property Rights and capital stock of Subsidiaries of the Company) of the Company or any reorganization, recapitalization or liquidation of the Company; or (z) any change in the present authorized capitalization of the Company or any amendment or other change to the Company’s Certificate of Incorporation or Bylaws. Subject to the proxy granted under Section 1.3 below, each Stockholder shall retain at all times the right to vote the Subject Shares in such Stockholder’s sole discretion, and without any other limitation, on any matters other than those set forth in this Section 1.2 that are at any time or from time to time presented for consideration to the Company’s stockholders generally.

1.3 Irrevocable Proxy. For so long as this Agreement has not been validly terminated in accordance with its terms, each Stockholder hereby irrevocably appoints Parent (and any Person or Persons designated by Parent) as its attorney-in-fact and proxy with full power of substitution and resubstitution, to the full extent of such Stockholder’s voting rights with respect to all such Stockholder’s Subject Shares (which proxy is irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of such Stockholder) and which appointment is coupled with an interest, including for purposes of Section 212 of the DGCL) to vote (or issue instructions to the record holder to vote), and to execute (or issue instructions to the record holder to execute) written consents with respect to, all such Stockholder’s Subject Shares in accordance with the provisions of Section 1.2. This proxy is coupled with an interest, was given to secure the obligations of such Stockholder under Section 1.2, was given in consideration of and as an additional inducement of Parent and Purchaser to enter into the Merger Agreement and shall be irrevocable, and such Stockholder agrees to execute any further agreement or form reasonably necessary or appropriate to confirm and effectuate the grant of the proxy contained herein and hereby revokes any proxy previously granted by such Stockholder with respect to the Subject Shares. Such proxy shall not be terminated by operation of any Law or upon the occurrence of any other event other than upon the valid termination of this Agreement in accordance with its terms. Parent may terminate this proxy with respect to a Stockholder at any time at its sole election by written notice provided to such Stockholder.
