The Parties agree not to commence any Proceeding relating hereto or thereto except in the Delaware Courts, other than Proceedings in any court of competent jurisdiction to enforce any judgment, decree, or award rendered by any Delaware Court. The Parties further agree that notice as provided herein shall constitute sufficient service of process and the Parties further waive any argument that such service is insufficient.

Notwithstanding the foregoing, during the pendency of the Chapter 11 Case, all Proceedings contemplated by this Section 11 shall exclusively be brought in the Bankruptcy Court and no other forum.

(b) The Parties hereby waive, to the fullest extent permitted by applicable law, any right they may have to a trial by jury in any Proceeding directly or indirectly arising out of or relating to this Agreement or the transactions contemplated hereby (whether based on contract, tort or any other theory).

12. Good Faith Cooperation; Further Assurances. Each Party hereby covenants and agrees to cooperate with each other in good faith in connection with, and shall exercise commercially reasonable efforts with respect to, the pursuit, approval, implementation, and consummation of the Restructuring Transactions, as well as the negotiation, drafting, execution, and delivery of the Definitive Documentation.

14. Debtors’ Fiduciary Obligations. Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement, the Plan, or anything included in any Definitive Document shall require any Debtor or any board of directors, board of managers, or similar governing body of any Debtor, after consulting with counsel, to take any action or to refrain from taking any action with respect to this Agreement, the Plan, or the Restructuring Transactions to the extent taking or failing to take such action would be inconsistent with applicable law or its fiduciary obligations under applicable law, and any such action or inaction pursuant to such exercise of fiduciary duties shall not be deemed to constitute a breach of this Agreement; provided that the Debtors shall give prompt written notice to counsel to the Plan Sponsor (electronic mail among counsel being sufficient) of any determination made under this Section.

15. Survival. Notwithstanding the termination of this Agreement pursuant to Section 7, [Section[s] *] shall survive such termination and shall continue in full force and effect in accordance with the terms hereof; provided that any liability of a Party for failure to comply with the terms of this Agreement shall survive such termination.

16. Headings. The headings of the sections, paragraphs, and subsections of this Agreement are inserted for convenience only and shall not affect the interpretation hereof or, for any purpose, be deemed a part of this Agreement.

17. Successors and Assigns; Severability. This Agreement is intended to bind and inure to the benefit of the Parties and their respective successors, permitted assigns, heirs, executors, administrators, and representatives. If any provision of this Agreement, or the application of any such provision to any person or entity or circumstance, shall be held invalid or unenforceable, in whole or in part, such invalidity or unenforceability shall attach only to such provision or part thereof and the remaining part of such provision hereof and this Agreement shall continue in full force and effect. Upon any such determination of invalidity, the Parties shall negotiate in good faith to modify this Agreement so as to effectuate the original intent of the Parties as closely as possible in a reasonably acceptable manner so that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. No assignment of this Agreement or of any rights or obligations hereunder may be made by any Party (by operation of law or otherwise) without the prior written consent of the other parties hereto and any attempted assignment without the required consents shall be void.

18. Relationship Among Parties. Unless expressly stated herein, this Agreement shall be solely for the benefit of the Parties and no other person or entity shall be a third-party beneficiary hereof. No Party shall have any responsibility for the transfer, sale, purchase, or other disposition of securities by any other entity by virtue of this Agreement. No prior history, pattern, or practice of sharing confidences among the Parties shall in any way affect or negate this understanding and agreement. The Parties have no agreement, arrangement, or understanding with respect to acting together for the purpose of acquiring, holding, voting, or disposing of any securities of the Company and do not constitute a “group” within the meaning of Rule 13d-5 under the Securities Exchange Act of 1934, as amended.
