its Debtor Affiliates, dated April 23, 2020 (as amended, the “Plan”), the Company agrees that the definition of “Convertible Notes Indenture Trustee” in the Plan, with respect to the  “Convertible Notes Indenture” (as defined in the Plan) shall mean the Successor Trustee.  Nothing contained herein shall be construed as a waiver by the Successor Trustee of any and all of its rights or remedies it may have (i) under the Indenture, or (ii) respecting any plan filed in the Debtors' chapter 11 cases, all of which rights and remedies are hereby expressly, fully and completely reserved. 
4.6This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to conflicts of laws principles thereof.
4.7This Agreement may be executed in any number of counterparts each of which shall be deemed an original, but such counterparts shall together constitute but one and the same instrument.

The Company agrees that it will provide Successor Trustee with such information as it may request in order for Successor Trustee to satisfy the requirements of the USA Patriot Act.
4.9This Agreement sets forth the entire agreement of the parties with respect to its subject matter, and supersedes and replaces any and all prior contemporaneous warranties, representations or agreements, whether oral or written, with respect to the subject matter of this Agreement other than those contained in this Agreement.
4.10The Company, Predecessor Trustee and Successor Trustee hereby acknowledge receipt of an executed counterpart of this Agreement and the effectiveness thereof.
