14. Entire Agreement; No Third-Party Beneficiaries. This Agreement (a) constitutes the entire agreement and understanding, and supersedes all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter of this Agreement and (b) shall not confer upon any Person other than the parties hereto any rights (including third-party beneficiary rights or otherwise) or remedies hereunder. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

15. Governing Law; Submission to Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to contracts executed in and to be performed entirely within that State, regardless of the Law that might otherwise govern under applicable principles of conflicts of Law thereof. Each of the parties hereto irrevocably agrees that any legal action or Proceeding with respect to this Agreement, and the rights and obligations arising hereunder, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware) (the “Delaware Courts”). Each of the parties hereto consents to service of process being made upon it through the notice procedures set forth in Section 13, irrevocably submits with regard to any such action or Proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated hereby in any court other than the aforesaid courts. Each of the parties hereto irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or Proceeding with respect to this Agreement, any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 15, any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and to the fullest extent permitted by the applicable Law, any claim that the suit, action or Proceeding in such court is brought in an inconvenient forum, the venue of such suit, action or Proceeding is improper or this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each party hereto expressly acknowledges that the foregoing waiver is intended to be irrevocable under the Law of the State

9

of Delaware and of the United States of America; provided, however, that each such party’s consent to jurisdiction and service contained in this Section 15 is solely for the purposes referred to in this Section 15 and shall not be deemed to be a general submission to such courts or in the State of Delaware other than for such purpose.

16. Waiver of Jury Trial. EACH PARTY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY, THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY.

17. Assignment; Successors. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned, in whole or in part, by operation of law or otherwise, by any of the parties without the prior written consent of the other parties, except that the Partnership may assign all or any of its rights and obligations hereunder to any direct or indirect wholly owned Subsidiary of the Partnership, and each of the Sponsors may Transfer any or all of the Covered Shares in accordance with Section 6(a); provided further that no assignment shall limit the assignor’s obligations hereunder. Subject to the preceding sentence, 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. Any purported assignment not permitted under this Section 17 shall be null and void.

18. Enforcement. The parties hereto each agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and it is accordingly agreed that the parties 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, in each case, in accordance with this Section 18, in the Delaware Courts, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that either party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity (it being understood that nothing in this sentence shall prohibit the parties hereto from raising other defenses to a claim for specific performance or other equitable relief under this Agreement). Each party further agrees that no party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 18, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

19. Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other terms, provisions and conditions 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 adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being

10

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 to the fullest extent permitted by applicable Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

20. Counterparts. This Agreement may be executed in counterparts (each of which shall be deemed to be an original but all of which taken together shall constitute 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 parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

21. Conflicts Committee. In addition to any other approvals required by the parties under this Agreement, whenever a determination, decision, action, approval, consent, waiver or agreement of the Partnership is required or may be given pursuant to this Agreement, such determination, decision, action, approval, consent, waiver or agreement must be authorized by the Conflicts Committee and, unless otherwise required by the Partnership Agreement or applicable Law, such action shall not require approval of the holders of Class A Shares.
