11. Specific Performance. Each of the parties hereto acknowledges and agrees that (a) the covenants, obligations and agreements contained in this Agreement relate to special, unique and extraordinary matters, and (b) irreparable damage would occur and each such party would not have any adequate remedy at Law in the event that any of the obligations, undertakings, covenants or agreements of the other parties to this Agreement were not performed in accordance with their 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 each of the parties hereto shall be entitled to seek an injunction or injunctions to prevent breaches or threatened breaches of this Agreement by each of the other parties hereto, and to enforce specifically the terms and provisions of this Agreement by a decree of specific performance, in accordance with Section 12, without the necessity of proving actual harm or damages or obtaining, furnishing or posting any bond or similar instrument therefor (and each such party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument), this being in addition to any other remedy to which such party is entitled at Law or in equity, and each of the parties hereto agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that such party has an adequate remedy at Law or that any award of specific performance or other equitable remedy is not an appropriate remedy for any reason at Law or in equity. Without limitation of the foregoing, each of the parties hereto hereby further acknowledges and agrees that during the Term, each party shall be entitled to seek specific performance to enforce specifically the terms and provisions of, and to prevent or cure breaches of the covenants required to be performed by each of the other parties hereto under this Agreement, in addition to any other remedy to which such party is entitled at Law or in equity, including such party’s right to terminate this Agreement pursuant to Section 10. Each of the parties hereto further agrees that it shall not take any position in any legal proceeding concerning this Agreement that is contrary to the terms of this Section 11.

12. Governing Law. This Agreement and all actions, proceedings, causes of action, claims or counterclaims (whether based on contract, tort, statute or otherwise) based upon, arising out of or relating to this Agreement or the actions of Parent, Merger Sub or the Company in the negotiation, administration, performance and enforcement thereof (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in connection with this Agreement or as an inducement to enter into this Agreement), shall be governed by, and construed in accordance with the Laws of the State of Delaware, including its statutes of limitations, 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, including any statutes of limitations, of any jurisdiction other than the State of Delaware.

13. Waiver. At any time and from time to time prior to the Effective Time, Parent and the Company may, to the extent legally allowed and except as otherwise set forth herein, (a) extend the time for the performance of any of the obligations or other acts of the other party hereto, as applicable; (b) waive any inaccuracies in the representations and warranties of the other party hereto contained herein or in any document delivered pursuant hereto; and (c) subject to the requirements of applicable Law, waive compliance by the other party hereto with any of the

agreements or conditions contained herein applicable to such party hereto (it being understood that Parent and Merger Sub shall be deemed a single party hereto solely for purposes of this Section 13). Any agreement on the part of a party hereto to any such extension or waiver will be valid only if set forth in an instrument in writing signed by such party hereto. Any delay in exercising any right pursuant to this Agreement will not constitute a waiver of such right.

14. Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE PURSUANT TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THAT SUCH PARTY HERETO MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING (WHETHER FOR BREACH OF CONTRACT, TORTIOUS CONDUCT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE MERGER. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY HERETO WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (ii) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (iii) IT MAKES THIS WAIVER VOLUNTARILY; AND (iv) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 14.

Subject to the preceding sentence, this Agreement will be binding upon and shall inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns. No assignment by any party hereto will relieve such party hereto of any of its obligations hereunder.

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 will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto.

Any such counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”), will be treated in all manner and respects as an original executed counterpart and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of an Electronic Delivery, as a defense to the formation of a contract, and each party hereto forever waives any such defense, except to the extent such defense relates to lack of authenticity.

21. Waiver of Appraisal. Each Stockholder hereby irrevocably waives, and agrees not to exercise, any rights of appraisal or rights of dissent from the Merger that such Stockholder may have with respect to the Subject Shares.

24. Interpretation and Construction.
