8.5Amendment; Waiver. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties. Any agreement on the part of either Party to any extension or waiver with respect to this Agreement shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of either Party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

8.6Expenses. All fees and expenses incurred in connection this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such fees and expenses, whether or not the transactions contemplated by this Agreement are consummated.

8.7Entire Agreement. This Agreement, together with the other documents and certificates delivered pursuant hereto, constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter of this Agreement.

8.8Assignment. 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 either Party without the prior written consent of the other Party. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and assigns.

8.9Specific Enforcement; Jurisdiction.

(a)The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions, or any other appropriate form of equitable relief, to prevent breaches of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement in any court referred to in Section 8.9(b), without the necessity of proving the inadequacy of money damages as a remedy (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at Law or in equity. Each of the Parties acknowledges and agrees that the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without such right, neither of the Parties would have entered into this Agreement.

(b)Each of the Parties hereby irrevocably submits to the exclusive jurisdiction of the courts of the State of Delaware for the purpose of any legal action, suit or proceeding arising out of or relating to this Agreement or any of the transactions contemplated hereby, and each of the Parties hereby irrevocably agrees that all claims with respect to such legal action, suit or proceeding may be heard and determined exclusively in such court. Each of the Parties (i) consents to submit itself to the personal jurisdiction of the courts of the State of Delaware in the event any legal action, suit or proceeding arises out of this Agreement or any of the transactions contemplated hereby, (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) irrevocably consents to the service of process in any legal action, suit or proceeding arising out of or relating to this Agreement or any of the transactions contemplated hereby, on behalf of itself or its property, in accordance with Section 8.2 (provided that nothing in this Section 8.9(b) shall affect the right of either Party to serve legal process in any other manner permitted by applicable Law) and (iv) agrees that it will not bring any legal action, suit or proceeding relating to this Agreement or any of the transactions contemplated hereby in any court other than the courts of the State of Delaware. The Parties agree that a final trial court judgment in any such legal action, suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law; provided, however, that nothing in the foregoing shall restrict either Party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

8.10Waiver of Jury Trial. Each Party hereby waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any legal action, suit or proceeding arising out of this Agreement or any of the transactions contemplated hereby. Each Party (a) certifies that no Representative, agent or attorney of the other Party has represented, expressly or otherwise, that such Party would not, in the event of any legal action, suit or proceeding, seek to enforce the foregoing waiver and (b) acknowledges that it and the other Party have been induced to enter into this Agreement by, among other things, the mutual waiver and certifications in this Section 8.10.

8.11Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of Laws thereof.

8.12Severability. If any term or other provision of this Agreement is 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 by this Agreement is not affected in any manner adverse to either Party.

8.13Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Party. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic image scan transmission shall be effective as delivery of a manually executed counterpart of this Agreement.

8.14Further Assurances. Each Party will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use its 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 Law to perform its obligations under this Agreement. Each Party shall use its reasonable best efforts to take, or cause to be taken, any and all actions and to do, or cause to be done, and to assist such other Party in doing, any and all things, necessary, proper or advisable to consummate and make effective the transactions contemplated by this Agreement.

8.15Certain Transaction-Related Taxes. All transfer, documentary, sales, use, stamp, recording fees, registration and similar Taxes and fees (including, without limitation, any penalties and interest) attributable to Seller’s sale of the Subject Shares to the Company pursuant to this Agreement shall be paid equally by the Company and Seller when due, and Seller shall, at its expense, file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, recording fees, registration and other Taxes. The Company shall be entitled to deduct and withhold from the Purchase Price all Taxes that the Company may be required to deduct and withhold under any provision of applicable Tax Law; provided that, the Company shall use commercially reasonable efforts to notify Seller at least three (3) days prior to the Closing Date of any such determination and the Parties shall cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such deduction or withholding. To the extent such amounts are so deducted or withheld, and remitted to the applicable Governmental Authority in accordance with applicable Tax Law, all such withheld amounts shall be treated as delivered to Seller hereunder.
