4.2 Amendment; Waiver. Any provision of this Agreement may be amended or waived during the Agreement Period if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement or, in the case of a

8

waiver, by each party against whom the waiver is to be effective. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege.

4.3 Termination. This Agreement shall automatically terminate and become void and of no further force or effect on the earlier of (i) the Effective Time, (ii) the termination of this Agreement by written notice from Parent to the Stockholders, (iii) the termination of the Merger Agreement in accordance with its terms, and (iv) with respect to any Stockholder, upon the entry without the prior written consent of such Stockholder into any material modification or amendment to the Merger Agreement, or any waiver of any of the Company’s rights under the Merger Agreement, in each case, that (A) reduces or changes the form of the consideration to be paid to such Stockholder in connection with the Merger (except as expressly contemplated pursuant to the terms of the Merger Agreement) or (B) creates any additional conditions to the consummation of the Merger (the period from the date hereof through such time being referred to as the “Agreement Period”); provided that (x) Section 4.1, Section 4.2, Section 4.5, Section 4.9, Section 4.10 and Section 4.15 shall survive such termination, and (y) upon termination of this Agreement, all obligations of the parties hereunder will terminate, without any liability or other obligation on the part of any party hereto to any Person in respect hereof or the transactions contemplated hereby, and no party shall have any claim against another (and no Person shall have any rights against such party), whether under contract, tort or otherwise, with respect to the subject matter hereof; provided that the termination of this Agreement shall not relieve any party from liability arising from fraud or any willful and intentional breach prior to such termination. For clarity, this Agreement shall not terminate upon a Change of Recommendation unless the Merger Agreement is terminated. To the extent applicable, each Stockholder hereby consents to the entry into the Merger Agreement for purposes of clause (iv) of Section 4.3 of the Original Agreement.

4.4 No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to any Subject Shares. All rights, ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to the Stockholders, and Parent shall have no authority to direct any Stockholder in the voting or disposition of any of the Subject Shares, except as otherwise provided herein.

4.5 Expenses. All costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs or expenses, whether or not the Transactions are consummated.

4.6 Representations and Warranties. The representations and warranties contained in this Agreement and in any certificate or other writing delivered pursuant hereto shall not survive the Effective Time or the termination of this Agreement.

4.7 Entire Agreement; Counterparts. This Agreement constitutes the entire agreement, and supersedes all other prior agreements and understandings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof and thereof, including the Original Agreement. This Agreement may be executed in counterparts (each of

9

which shall be deemed to be an original but all of which taken together shall constitute one and the same agreement) and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by electronic communication, facsimile or otherwise) to the other parties. Until and unless each party has received a counterpart hereof signed by the other parties hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

4.8 Assignment; Third Party Beneficiaries. The provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties and their respective successors and assigns. No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party; provided, however, that Parent may assign any of its rights hereunder to a wholly owned direct or indirect Subsidiary of Parent without the prior written consent of the Stockholders, but no such assignment shall relieve Parent of any of its obligations hereunder. This Agreement is not intended to and shall not confer upon any Person other than the parties hereto (and their respective heirs, successors and permitted assigns) any rights, remedies, benefits, obligations, liabilities or claims hereunder.

4.9 Governing Law; Jurisdiction.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice or conflict of laws provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

(b) Each of the parties hereto hereby agrees that (i) all actions and proceedings arising out of or relating to this Agreement shall be heard and determined in the Chancery Court of the State of Delaware and any state appellate court therefrom sitting in New Castle County in the State of Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), (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, and (iii) a final Judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the Judgment or in any other manner provided by Law.

(c) Each party irrevocably consents to the service of process outside the territorial jurisdiction of the courts referred to in this Section 4.9 in any such action or proceeding by mailing copies thereof by registered or certified United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to this Agreement. However, the foregoing shall not limit the right of a party to effect service of process on the other party by any other legally available method.

4.10 WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES HERETO ARISING OUT OF OR RELATING TO THIS AGREEMENT.

10

4.11 Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction or other Governmental Entity to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms, provisions and conditions of this Agreement shall nevertheless remain in full force and effect. 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 to the fullest extent permitted by applicable law in a mutually acceptable manner to the end that the transactions contemplated by this Agreement are fulfilled to the extent possible.

4.12 Enforcement. The parties agree 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 any federal court located in the State of Delaware or any Delaware state court, this being in addition to any other remedy to which they are entitled at law or in equity.

4.13 Construction. When a reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein and the rules and regulations promulgated thereunder. References to a Person are also to its permitted assigns and successors.

4.14 No Presumption. Each of the parties agrees that he, she or it has had the opportunity to review this Agreement with counsel of his, her or its own choosing and, therefore, waives the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

4.15 Obligations; Stockholder Capacity. The obligations of each Stockholder under this Agreement are several and not joint, and no Stockholder shall have any liability or obligation under this Agreement for any breach hereunder by any other Stockholder. Each Stockholder is signing and entering this Agreement solely in his, her or its capacity as the beneficial owner of such Stockholder’s Subject Shares. Notwithstanding anything to the contrary in this Agreement, no Stockholder makes any agreement or understanding in this Agreement in such Stockholder’s

11

capacity as an employee, officer or director of the Company, and nothing herein (i) shall limit or affect in any way any actions that may hereafter be taken by him, her or it in his, her or its capacity as an employee, officer or director of the Company, including in exercising rights under the Merger Agreement, and no such actions or omissions shall be deemed a breach of this Agreement or (ii) shall be construed to prohibit, limit or restrict him, her or it from exercising his, her or its fiduciary duties as an employee, officer or director to the Company or its stockholders.
