(a) This
Agreement shall be construed and enforced in accordance with, and the rights of the Parties shall be governed by, the laws of the State
of Delaware, without giving effect to the conflict of laws principles thereof. The Parties irrevocably agree that any legal action, suit,
or proceeding (each, a “Proceeding”) arising out of or relating to this Agreement brought by any Party or its successors or
assigns shall be brought and determined in the Bankruptcy Court or, if the Bankruptcy Court shall not then have jurisdiction, in any federal
or state court in New Castle County, Delaware (the “Delaware Courts”), and the Parties hereby irrevocably and generally submit
to the exclusive jurisdiction of the Delaware Courts and any court to which appeals from the Delaware Courts may be adjudicated for themselves
and with respect to their property, and unconditionally with respect to any Proceeding arising out of or relating to this Agreement and
the Restructuring. 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. The Parties hereby irrevocably and unconditionally waive and agree not to assert that a Proceeding
in any Delaware Court is brought in an inconvenient forum or the venue of such Proceeding is improper. 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. Subject to
the terms hereof, the Parties shall take such action as may be reasonably necessary or reasonably requested by any Party to carry out
the purposes and intent of this Agreement, and shall refrain from taking any action that would frustrate the purposes and intent of this
Agreement.


 






    9


     


    

 


13. Independent
Analysis. Each Party hereby confirms that its decision to execute this Agreement has been based upon its independent assessment
of documents and information available to it, as it has deemed appropriate.


 


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.


 



19. Prior
Negotiations; Entire Agreement. This Agreement, including the exhibits and schedules hereto (including the Term Sheet), constitutes
the entire agreement of the Parties, and supersedes all other prior negotiations regarding the subject matters hereof and thereof.


 


20. Counterparts.
This Agreement may be executed in several counterparts, each of which shall be deemed to be an original, and all of which together
shall be deemed to be one and the same agreement. Execution copies of this Agreement delivered by facsimile or PDF shall be deemed to
be an original for the purposes of this paragraph.
