EACH OF THE PARTIES (1) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (2) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.6(c).

5.7. Counterparts. This Agreement may be executed in one or more counterparts (including via facsimile, .pdf or other electronic means), and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

5.8. Entire Agreement. This Agreement, together with Schedule A, constitutes the entire agreement of the parties and supersedes all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof.

5.9. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of 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.

5.10. Specific Performance. The parties hereto agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at law would exist and damages would be difficult to determine. It is accordingly agreed that Parent and Purchaser, on the one hand, and each of the Stockholders, on the other hand, 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 against the other exclusively in the Chancery Court of the State of Delaware and any state appellate court therefrom within 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) and any such injunction shall be in addition to any other remedy to which any party is entitled, at law or in equity. In connection with any action for specific performance, each party hereby irrevocably waives any requirement for proof of actual damages or the securing or posting of any bond in connection with the remedies referred to in this Section 5.10.

5.11. Headings. 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.

5.12. Mutual Drafting; Interpretation. Each party hereto has participated in the drafting of this Agreement, which each party acknowledges is the result of extensive negotiations between the parties. If an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision. For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa, the masculine gender shall include the feminine and neuter genders, the feminine gender shall include the masculine and neuter genders and the neuter gender shall include masculine and feminine genders. As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.” Except as otherwise indicated, all references in this Agreement to “Sections,” “Articles” and “Schedules” are intended to refer to Sections, Articles and Schedules to this Agreement. Schedule A attached to this Agreement constitutes a part of this Agreement and is incorporated herein for all purposes. All references to Schedule A shall be deemed to refer to Schedule A as updated and delivered by the Stockholders in accordance with Section 4.6. The words “hereof,” “hereto,” “hereby,” “herein,” “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not to any particular section or article in which such words appear. The words “shall” and “will” may be used interchangeably herein and shall have the same meaning. All references in this Agreement to “$” are references to United States dollars. Unless otherwise specifically provided for herein, the term “or” shall not be deemed to be exclusive. Except as otherwise specified, (i) references to any statute shall be deemed to refer to such statute as amended from time to time and to any rules or regulations promulgated thereunder, (ii) references to any Person include the successors and permitted assigns of that Person, and (iii) references from or through any date mean from and including or through and including, respectively.

5.13. Further Assurances. Parent, the Purchaser and each 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 under this Agreement.

5.14. Capacity as Stockholder. Each Stockholder signs this Agreement solely in such Stockholder’s capacity as a Stockholder of the Company, and not in such Stockholder’s capacity as a director, officer or

employee of the Company or any Company Subsidiary or in the Stockholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust. Notwithstanding anything herein to the contrary, nothing herein shall in any way restrict a director or officer of the Company in the taking of any actions (or failure to act) in his or her capacity as a director or officer of the Company or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust, or in the exercise, in such Stockholder’s sole discretion, of his or her fiduciary duties as a director or officer of the Company or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust, or prevent or be construed to create any obligation on the part of any director or officer of the Company from taking any action in his or her capacity as such director, officer, trustee or fiduciary.

5.15. No Agreement Until Executed. This Agreement shall not be effective and shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding obligating the parties hereto unless and until (i) the Merger Agreement is validly executed by all parties thereto and (ii) as to a Stockholder, this Agreement is executed by Parent, the Purchaser and such Stockholder.

5.16. Stockholder Obligation Several and Not Joint; Independent Nature of Obligations. The obligations of each Stockholder hereunder shall be several and not joint, and no Stockholder shall be liable for any breach of the terms of this Agreement by any other Stockholder. Each of Parent and Purchaser, on the one hand, and each Stockholder, on the other, shall be entitled to enforce its rights under this Agreement against the other, and it shall not be necessary for any other Stockholder to be joined as an additional party in any proceeding for such purpose. No Stockholder may enforce this Agreement against any other Stockholder party hereto. A default by any Stockholder of its obligations pursuant to this Agreement shall not relieve any other Stockholder of any of its obligations to Parent and/or the Purchaser under this Agreement.

5.17. No Ownership Interest. Until receipt of payment in full by the Stockholder for all of its Subject Shares pursuant to the Merger Agreement, except as otherwise provided herein, nothing contained in this Agreement shall be deemed to vest in Parent or the Purchaser any direct or indirect ownership or incidence of ownership of or with respect to the Subject Shares. Except as otherwise provided herein or in the Merger Agreement, all rights, ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to each applicable Stockholder, and neither Parent nor the Purchaser shall have any authority to manage, direct, restrict, regulate, govern, or administer any of the policies or operations of the Company or exercise any power or authority to direct such Stockholder in the voting of any of the Subject Shares.
