Laws or result in the Company being required to register any class of its equity securities with the SEC. As used herein, the term “Expiration Time” as it applies to any Stockholder shall mean the earlier of (A) the Effective Time and (B) the termination of the Merger Agreement in accordance with its terms. Any Transfer in violation of this Section 1.1 shall be null and void ab initio with respect to Shares so transferred.

1.2 From the Agreement Date until the Expiration Time and except pursuant to the terms of this Agreement, each Stockholder, as to himself, herself or itself (severally and not jointly), agrees he, she or it shall not, directly or indirectly, grant any proxies or powers of attorney with respect to any of the Shares, deposit any of the Shares into a voting trust, or enter into a voting agreement with respect to any of the Shares.

1.3 Any shares of Company Capital Stock that a Stockholder purchases or with respect to which such Stockholder otherwise acquires beneficial ownership on or after the Agreement Date and prior to the Expiration Time, including, without limitation, by reason of any (a) exercise of Company Options or vesting and conversion of Company RSUs or Company PRSAs or (b) stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into capital stock), reorganization, recapitalization, reclassification, combination, exchange of shares or other similar transaction (collectively, the “New Shares”), shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares and shall be deemed to be Shares for the purposes hereof; provided, however, that a Stockholder shall be permitted to sell or net settle a sufficient number of Shares or New Shares to cover the tax withholding obligations resulting from the vesting and conversion of Company RSUs or Company PRSAs or the exercise of Company Options and to cover the payment of the exercise price related to the exercise of Company Options.

2. Agreement to Vote Shares. From the Agreement Date until the Expiration Time, at every meeting of the Company Stockholders called with respect to any of the following, and at every adjournment or postponement thereof, each Stockholder shall (as to himself, herself or itself (severally and not jointly)) or shall cause the holder of record of any applicable record date to, be present (in person or by proxy) and irrevocably and unconditionally vote (or consent to be voted) the shares of Company Capital Stock beneficially owned by such Stockholder (the “Shares”) in respect of which such Stockholder is entitled to vote at any such meeting (a) in favor of (i) the adoption of the Merger Agreement; and (ii) approval of any proposal to adjourn or postpone the meeting to a later date, if there are not sufficient votes for the adoption of the Merger Agreement; (b) in favor of any other matter considered at any such meeting of the Company Stockholders that the Company Board has (A) determined is necessary or desirable for the consummation of the Merger; (B) disclosed in the Proxy Statement or other written materials distributed to all Company Stockholders and (C) recommended that the Company Stockholders adopt; and (c) against any Acquisition Proposal.

The proxy granted pursuant to this Section 2.1 is coupled with an interest and shall be irrevocable until the Expiration Time. Until the Expiration Time, such Stockholder will take such further action and will execute such other instruments as may be necessary to effectuate the intent of this proxy.

5.3 Specific Performance; Injunctive Relief. The parties hereto acknowledge that Parent will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of any Stockholder set forth herein. Therefore, it is agreed that, in addition to any other remedies that may be available to Parent upon any such violation of this Agreement, Parent shall have the right to enforce such covenants and agreements by injunctive relief, specific performance, or by any other means available to Parent at law or in equity and each Stockholder hereby waives any and all defenses that could exist in its favor in connection with such injunction or enforcement and waives any requirement for the security or posting of any bond in connection with such injunction or enforcement.

5.5 Entire Agreement; Nonassignability; Parties in Interest; Assignment. This Agreement and the documents, instruments and other agreements among the parties as contemplated by, referred to herein or delivered pursuant hereto (a) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and (b) are not intended to confer,

5

and shall not be construed as conferring, upon any Person other than the parties hereto any rights or remedies hereunder. The representations and warranties and covenants of each Stockholder contained herein shall not survive the Closing, and no claim may be brought with respect to any breach of any representation, warranty or covenant hereunder following the Closing. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise, by any Stockholder without the prior written consent of Parent, and any such assignment or delegation that is not consented to shall be null and void. Parent may assign this Agreement to any direct or indirect wholly owned subsidiary of Parent without the prior written consent of any Stockholder. Subject to the preceding two sentences, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by and against, the parties hereto and their respective successors and assigns (including any Person to whom any Shares are Transferred).

5.6 Amendment; Waiver. Subject to applicable Law, the parties hereto may amend this Agreement as it applies to each Stockholder at any time by execution of an instrument in writing signed on behalf of each of Parent and Stockholder. At any time, either Parent or any Stockholder (as to himself, herself or itself) may, to the extent legally allowed, extend the time for the performance of any of the obligations or other acts of the other parties, as applicable, waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto and waive compliance with any of the agreements or conditions for the benefit of such party contained herein. Any agreement on the part of Parent or any Stockholder to any such waiver shall be valid only if set forth in an instrument in writing signed on behalf of the other. Without limiting the generality or effect of the preceding sentence, no delay in exercising any right under this Agreement shall constitute a waiver of such right, and no waiver of any breach or default shall be deemed a waiver of any other breach or default of the same or any other provision herein.

5.7 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

5.8 Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party hereto shall be deemed cumulative with and not exclusive of any other remedy conferred by this Agreement, or by applicable Law on such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

5.9 Governing Law. The internal laws of the State of Delaware, irrespective of its conflicts of law principles, shall govern the validity of this Agreement, the construction of its terms, and the interpretation and enforcement of the rights and duties of the parties hereto. The parties hereto hereby irrevocably submit to the exclusive jurisdiction of the Chosen Courts solely in respect of the interpretation and enforcement of this Agreement and of the documents referred to herein, and in respect of the Merger, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or thereof, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such Chosen Courts. The parties hereto hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 5.2 or in such other manner as may be permitted by any applicable Law shall be valid and sufficient service thereof.
