Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified.

Each of the parties, to the maximum extent permitted by applicable law, (a) irrevocably submits to the personal jurisdiction of any state or federal court sitting in the state of Delaware, as well as to the jurisdiction of all courts to which an appeal may be taken from such courts, in any suit, action or proceeding arising out of or relating to this Agreement (except as provided in Section 9(k)(i) above), (b) agrees that all claims in respect of such suit, action or proceeding shall be brought, heard and determined exclusively in the Delaware Court of Chancery (provided that, in the event that subject matter jurisdiction is unavailable in that court, then all such claims shall be brought, heard and determined exclusively in any other state or federal court sitting in the state of Delaware), (c) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from such court, (d)

12

agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court, and (e) expressly waives, and agrees not to plead or to make any claim that any such action or proceeding is subject (in whole or in part) to a jury trial, (f) agrees (1) to the extent such party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such party’s agent for acceptance of legal process, and (2) that, to the fullest extent permitted by applicable law, service of process may also be made on such party by prepaid certified mail with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service, and that service made pursuant to (f)(1) or (2) above shall, to the fullest extent permitted by applicable law, have the same legal force and effect as if served upon such party personally within the State of Delaware and (g) waives, to the fullest extent permitted by applicable law, any objection it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. For purposes of implementing the parties’ agreement to appoint and maintain an agent for service of process in the State of Delaware, each such party that has not as of the date hereof already duly appointed such an agent in Delaware does hereby appoint Universal Registered Agents, Inc., as such agent. Each of the parties waives any defense of inconvenient forum to the maintenance of any action or proceeding brought in accordance with this paragraph. Each of the parties further consents and agrees that, to the maximum extent permitted by applicable law, process in any suit, action or proceeding may be served on such party in accordance with the notice provisions of Section 9(f) of this Agreement.

(iii) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT, OR ATTORNEY OF ANY PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATION OF THIS WAIVER, (C) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (D) EACH OTHER PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

(l) Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with its terms, and that monetary damages, even if available, would not be an adequate remedy therefor. Accordingly, the parties hereto agree that the parties (as well as the Majority Investors and the Company as set forth in Section 9(j)) shall be entitled to an injunction or injunctions, or any other appropriate form of equitable relief, to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof, 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

13

of any bond in connection with such remedy), in addition to any other remedy to which they are entitled at law or in equity. The parties further agree that neither the commencement of any action pursuant to this Section 9(l) nor anything contained in this Section 9(l) shall restrict or limit any party’s or the Company’s (as a third party beneficiary under this Agreement) right to pursue any other remedies under this Agreement that may be available then or thereafter.

(m) Interpretation. The descriptive headings used herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of 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.” The parties hereto have participated jointly in the negotiation and drafting of this Agreement. No provision of this Agreement shall be interpreted for or against any party hereto because that party or its legal representatives drafted the provision. The word “or” shall be deemed to be inclusive. 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 any particular section in which such words appear.

(n) Counterparts. This Agreement may be executed and delivered (including by facsimile or other form of electronic transmission) in one or more counterparts, 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. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile or other electronic delivery shall be sufficient to bind the parties to the terms and conditions of this Agreement and may be signed electronically.

(o) Expenses. Except as otherwise provided in the JBA, each party hereto shall pay such party’s own expenses incurred in connection with this Agreement.

(p) No Ownership Interest. Nothing contained in this Agreement shall be deemed, upon execution, to vest in Parent any direct or indirect ownership or incidence of ownership of or with respect to any Covered Shares, and Parent shall have no authority to manage, direct, superintend, restrict, regulate, govern or administer any of the policies or operations of the Company or exercise any power or authority to direct Shareholder in the voting of any of the Covered Shares, except as otherwise provided herein.
