Such Stockholder also agrees that immediately following the execution of this Agreement such Stockholder shall, and, to the extent applicable, shall cause each of its Affiliates and subsidiaries to, and shall use such Stockholder’s reasonable best efforts to cause its and their representatives to, cease any solicitations, discussions or negotiations with any Person (other than the Parties and their respective representatives) conducted heretofore in connection with an Acquisition Proposal or any inquiry or request for information that could reasonably be expected to lead to, or result in, an Acquisition Proposal.

15. Governing Law and Venue; Service of Process; Waiver of Jury Trial.

(a) This Agreement, and all claims or causes of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to principles or rules of conflicts of laws to the extent such principles or rules are not mandatorily applicable and would require or permit the application of the Laws of another jurisdiction other than the State of Delaware.

(b) In addition, each of the parties (i) consents to submit itself, and hereby submits itself, to the personal jurisdiction of the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction, any state or federal court located in the State of Delaware having subject matter jurisdiction, 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, and agrees not to plead or claim any objection to the laying of venue in any such court or that any judicial proceeding in any such court has been brought in an inconvenient forum, (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 such court does not have subject matter jurisdiction, any state or federal court located in the State of Delaware having subject matter jurisdiction, and (iv) consents to service of process being made through the notice procedures set forth in Section 11.

This Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns.

17. Enforcement. The rights and remedies of the parties shall be cumulative with and not exclusive of any other remedy conferred hereby.

It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, including each Stockholder’s obligations to vote its Covered Shares as provided in this Agreement, in the Court of Chancery of the State of Delaware or, if under applicable law exclusive jurisdiction over such matter is vested in the federal courts, any state or federal court located in the State of Delaware, without proof of actual damages or otherwise (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.

18. Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms and provisions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated, so long as the economic and legal substance of the transactions contemplated hereby,

taken as a whole, are not affected in a manner materially adverse to any Party hereto. Upon such a determination, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

19. Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement, it being understood that each Party need not sign the same counterpart. This Agreement shall become effective when each Party shall have received a counterpart hereof signed by all of the other parties. Signatures delivered electronically or by facsimile shall be deemed to be original signatures.
