ARTICLE I

Agreements

SECTION 1.01 Agreement to Tender.

(a) The Stockholder agrees to accept the Offer with respect to all the Shares beneficially owned by the Stockholder and to tender, or cause to be tendered, all such Shares, free and clear of any Liens, pursuant to the Offer. Such tender shall be made no later than the 5th business day after commencement of the Offer. Without limiting the generality of the foregoing, the Stockholder shall (i) deliver to the Paying Agent (A) a letter of transmittal with respect to the Stockholder’s Shares complying with the terms of the Offer, (B) to the extent applicable, a Certificate representing such Shares, and (C) all other documents or instruments required to be delivered by other holders of Company Common Stock pursuant to the terms of the Offer, or (ii) instruct and otherwise use reasonable efforts to cause the Stockholder’s broker and, if applicable, such other person that is the holder of record of any Shares beneficially owned by the Stockholder, to tender such Shares pursuant to and in accordance with this Section 1.01(a) and the terms of the Offer. The Stockholder shall not withdraw, or cause to be withdrawn, any Shares tendered pursuant to the Offer unless this Agreement is terminated pursuant to Section 4.01 or the Offer is terminated in accordance with the terms of the Merger Agreement. Merger Sub shall pay the Stockholder for any Shares tendered (and not withdrawn) in accordance with the provisions of the Merger Agreement. The Stockholder agrees to (x) permit Parent and Merger Sub to publish and disclose in the Offer Documents and any Proxy Statement (including all related documents and schedules filed with the SEC), its identity and ownership of shares of Common Stock of the Company, the nature of its commitments under this Agreement and any other information required by applicable Law or that Parent may reasonably request, in each case subject to the Stockholder’s prior approval (not to be unreasonably withheld) and (y) promptly provide to Parent or Merger Sub, as applicable, any such information. The Stockholder shall promptly notify Parent of any required corrections of which the Stockholder becomes aware with respect to any written information supplied by it specifically for use in any such disclosure document, if and to the extent that any shall have become false or misleading in any material respect. The Stockholder shall not issue any press release or make any other public statement with respect to the transactions contemplated by this Agreement and the Merger Agreement without the prior written consent of Parent, except as such release or statement may be required by applicable Law or the rules and regulations of any applicable United States securities exchange or regulatory or Governmental Entity to which Stockholder is subject or submits.

(b) Notwithstanding anything in this Agreement to the contrary, nothing herein shall require the Stockholder to exercise any option to purchase shares of Company Common Stock or to tender any securities not outstanding at the relevant time.

(c) The Stockholder acknowledges that the obligations to tender, or cause to be tendered, and not to withdraw, or cause to be withdrawn, the Shares as provided herein require the Stockholder to tender, or cause to be tendered, the Shares to Merger Sub in the event that the parties to the Merger Agreement adjust the terms and conditions of the Offer; provided that, following any such adjustment to the Offer, (i) the Offer Price shall be no less than as set forth in the Merger Agreement on the date hereof and (ii) the consideration paid to the Stockholder for Shares tendered in the Offer is equal to the highest consideration paid to any other holder of Company Common Stock for shares of Company Common Stock tendered in the Offer (any adjustment to the terms and conditions of the Offer by Parent or Merger Sub that is inconsistent with clause (i) or (ii) of the foregoing proviso, an “Adverse Amendment”).

SECTION 1.02 Agreement to Vote. The Stockholder agrees that, from and after the date hereof and unless this Agreement terminates pursuant to Section 4.01, at the Company Stockholders Meeting or any other meeting of the stockholders of the Company, however called, and at every adjournment or postponement thereof, or in any other circumstance upon which a vote of all or some of the stockholders of the Company is sought, relating to any proposed action by the stockholders of the Company with respect to the matters set forth in Section 1.02(b) below:

(a) the Stockholder shall appear at each such meeting or otherwise cause the Shares beneficially owned by the Stockholder to be counted as present thereat for purposes of calculating a quorum;

(b) the Stockholder shall, and shall cause any holder of record of Shares on any applicable record date to vote (or cause to be voted), in person or by proxy, all the Shares beneficially owned by the Stockholder (i) in favor of adoption of the Merger Agreement and any other action of the Company’s stockholders requested in furtherance thereof, including any proposal to adjourn the meeting if there are not sufficient votes for the adoption of the Merger Agreement on the date on which such meeting is held, and (ii) against any other action, agreement or transaction submitted for approval to the stockholders of the Company that (A) could reasonably be expected to lead to a Company Takeover Proposal, (B) would breach any covenant, representation or warranty or any other obligation or agreement of Stockholder under this Agreement, or (C) is intended or would reasonably be expected to impede, interfere with, discourage, adversely affect, delay or prevent the Offer, the Merger or the Transactions or change in any manner that is adverse to the consummation of the Offer, the Merger or the Transactions the voting rights of any class of shares of the Company (including by way of amendments to the Company Charter or Company Bylaws). The Stockholder acknowledges that the obligations set forth in this Section 1.02(b) shall apply whether or not there has been an Adverse Recommendation Change; and

(c) the Stockholder hereby irrevocably grants a limited proxy to, and appoints, Parent and any designee of Parent, and each of them individually, its proxies and limited attorneys-in-fact, with full power of substitution and resubstitution, to vote, or execute and deliver a proxy to vote, during the term of this Agreement with respect to the Shares in accordance with this Section 1.02. This limited proxy and power of attorney is given in connection with, and in consideration of, the execution of the Merger Agreement by Parent and Merger Sub, and to secure the performance of the duties of the Stockholder under this Agreement. The Stockholder shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this limited proxy. This limited proxy and power of attorney granted by the Stockholder shall be irrevocable during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by the Stockholder with respect to the Shares. The limited power of attorney granted by the Stockholder herein is a durable power of attorney and shall survive the dissolution, bankruptcy, death or incapacity of the Stockholder. The limited proxy and power of attorney granted hereunder shall terminate upon the termination of this Agreement. The parties hereto acknowledge and agree that neither Parent, nor any of its stockholders or affiliates, nor any of their partners, directors, officers, employees, agents or representatives of any of them, shall incur any liability to any stockholder directly or indirectly in connection with, or as a result of, any exercise of the limited proxy granted to Parent or any designee of Parent pursuant to this Section 1.02(c).

SECTION 1.03 No Solicitation. The Stockholder shall not, nor shall the Stockholder authorize or permit any of its Affiliates (which for the avoidance of doubt shall not include any other stockholder of the Company solely by virtue of such stock ownership) or any of its directors, officers, employees, agents, investment bankers, financial advisors, attorneys, accountants or other advisors or representatives (collectively, “Representatives”) to, directly or indirectly, (i) initiate, solicit, knowingly facilitate or knowingly encourage any inquiry or the making of any proposal that constitutes or could reasonably be expected to lead to a Company Takeover Proposal, (ii) enter into any letter of intent, memorandum of understanding or other agreement, arrangement or understanding relating to, or that could reasonably be expected to lead to, a Company Takeover Proposal, or (iii) continue or otherwise participate in any discussions or negotiations regarding, furnish to any Person any information or data with respect to, or otherwise cooperate with or take any other action to knowingly facilitate any proposal that (A) constitutes, or could reasonably be expected to lead to, a Company Takeover Proposal or (B) requires that the Company abandon, terminate or fail to consummate the Offer or the Transactions. The Stockholder and each of its Affiliates and Representatives shall (i) immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons or their Representatives conducted prior to the date of this Agreement with respect to any Company Takeover Proposal and (ii) use its reasonable best efforts promptly to inform its Representatives of the obligations undertaken in this Section 1.03. Without limiting the foregoing, any violation of the restrictions set forth in this Section 1.03 by any Representative, whether or not such Person is purporting to act on behalf of the Stockholder shall be deemed to be a breach of this Section 1.03 by the Stockholder.

SECTION 4.08 Specific Performance; Jurisdiction. Each party hereto agrees that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Court of Chancery of the State of Delaware or, if the Court of Chancery of the State of Delaware shall be unavailable, any Federal court located in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each party hereto irrevocably waives any defenses based on adequacy of any other remedy, whether at law or in equity, that might be asserted as a bar to the remedy of specific performance of any of the terms or provisions hereof or injunctive relief in any action brought therefor by any other party hereto. Each of the parties further agrees to waive any requirements for the securing or posting of any bond in connection with obtaining any such equitable relief. In addition, each of the parties hereto (i) irrevocably submits itself to the personal jurisdiction of the Court of Chancery of the State of Delaware or any Federal court located in the State of Delaware in the event any dispute arises out of this Agreement or any of the transactions contemplated by this Agreement, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (iii) agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the Court of Chancery of the State of Delaware or, if the Court of Chancery of the State of Delaware shall be unavailable, any Federal court sitting in the State of Delaware, (iv) waives any right to trial by jury with respect to any suit, action or proceeding directly or indirectly related to or arising out of this Agreement or any Transaction and (v) consents to service being made through the notice procedures set forth in Section 4.03.

Parent agrees to take any and all action, including the filing of any and all documents, that may be necessary to establish and continue such appointment in full force and effect as aforesaid.

SECTION 4.09 Amendment. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

SECTION 4.10 Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule or 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. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

SECTION 4.11 Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties without the prior written consent of the other parties. Any purported assignment without such consent shall be void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns. The Stockholder agrees that this Agreement and the obligations hereunder shall attach to the Stockholder’s Shares and shall be binding upon any person to whom legal or beneficial ownership of such Shares shall pass, whether by operation of law or otherwise, including the Stockholder’s successors and assigns. This Agreement is not intended to confer upon any person other than the parties hereto any rights or remedies hereunder.

SECTION 4.12 No Waiver. The terms and provisions hereof may not be waived except by an instrument signed on behalf of the party waiving compliance. The failure of any party to exercise any right, power or remedy provided under this Agreement or otherwise available in respect of this Agreement at law or in equity, or to insist upon compliance by any other party with its obligations under this Agreement, and any custom or practice of the parties at variance with the terms of this Agreement, shall not constitute a waiver by such party of such party’s right to exercise any such or other right, power or remedy or demand such compliance.

SECTION 4.13 Further Assurances. Parent, Merger Sub and the Stockholder will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use their respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws and regulations, to perform their respective obligations as expressly set forth under this Agreement.
