Section 10.4 Jurisdiction; Service of Process. Any action or proceeding seeking to enforce any provision of, or based on any right arising out of, this Agreement shall be exclusively brought against any of the parties in the District Court, or the courts of the State of New York in the event that the District Court does not have or cannot acquire jurisdiction in such action or proceeding, and each of the parties consents to the jurisdiction of such courts (and of the appropriate appellate courts) in any such action or proceeding and waives any objection to venue laid therein. Process in any action or proceeding referred to in the preceding sentence may be served on any party anywhere in the world.

Section 10.5 Further Assurances. The parties agree (a) to furnish upon request to each other such further information, (b) to execute and deliver to each other such other documents, and (c) to do such other acts and things, all as any other party may reasonably request for the purpose of carrying out the intent of this Agreement and the documents referred to in this Agreement.

Section 10.6 Waiver. The rights and remedies of the parties to this Agreement are cumulative and not alternative. Neither the failure nor any delay by any party in exercising any right, power, or privilege under this Agreement or the documents referred to in this Agreement will operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right, power, or privilege. To the maximum extent permitted by applicable Legal Requirements, (a) no claim or right arising out of this Agreement or the documents referred to in this Agreement can be discharged by any party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other parties hereto; (b) no waiver that may be given by a party will be applicable except in

the specific instance for which it is given; and (c) no notice to or demand on one party will be deemed to be a waiver of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

Section 10.7 Entire Agreement; Amendment. This Agreement supersedes all prior agreements between the parties with respect to its subject matter, whether oral or written, and constitutes (along with the documents referred to in or contemplated by this Agreement, including, without limitation, the exhibits hereto) a complete and exclusive statement of the terms of the agreement between the parties with respect to its and their subject matter. This Agreement may not be amended except by a written agreement executed by the parties hereto.

Section 10.8 Enforcement of Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the parties will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled at law or in equity.

Section 10.9 Assignments, Successors, and No Third-Party Rights. No party may assign any of its rights under this Agreement without the prior written consent of the other parties, except Seller may assign its rights and obligations under this Agreement to its Affiliates. Subject to the preceding sentence, this Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the parties. Nothing expressed or referred to in this Agreement will be construed to give any Person other than the parties to this Agreement (and their permitted successors and assignees) any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement, except that the Receiver is an intended third-party beneficiary of this Agreement and is entitled to enforce the same as if a party hereto with respect to the provisions hereof. Except as otherwise set forth in this Section 10.9, this Agreement and all of its provisions and conditions are for the sole and exclusive benefit of the parties to this Agreement and their successors and permitted assigns. Any attempted assignment in violation of this Agreement shall be null and void ab initio.

Section 10.10 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

Section 10.11 Section Headings; Construction. The headings of Sections in this Agreement are provided for convenience only and will not affect its construction or interpretation. All references to “Section” or “Sections” refer to the corresponding Section or Sections of this Agreement. All words used in this Agreement will be construed to be of such gender or number as the circumstances require. Unless otherwise expressly provided, the word “including” does not limit the preceding words or terms.

Section 10.12 Governing Law. This Agreement will be governed by the laws of the State of New York without regard to conflicts of law principles.

Section 10.13 Counterparts. This Agreement may be executed in counterparts and by facsimile signature, all of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement.

Section 10.14 Receiver. Buyers expressly, jointly and severally, acknowledge and agree, that (i) this Agreement is executed by the Receiver, not individually or personally, but solely in his capacity as the Receiver for Seller, among others, in the exercise of the powers and authority conferred and vested in him by the District Court Orders, (ii) any obligation, representation, warranty, undertaking, agreement or covenant by Seller or the Receiver is made and intended not as personal obligation, representations, warranties, undertakings, agreements and covenants by the Receiver but is made and intended solely for the purpose of binding only Seller and (iii) under no circumstances shall the Receiver be personally liable for the payment of any liability, expense, claim or other matter arising under this Agreement, the Seller Closing Documents or in connection with the Contemplated Transactions, or be liable for the breach or failure of any obligation, representation, warranty, undertaking, agreement or covenant made or undertaken by Seller under this Agreement.
