The Parties agree that the Specified Intercompany Agreements are being maintained in effect solely to facilitate the Specified Intercompany Agreement Purpose, and each of SpinCo and RMT Partner does hereby remise, release and forever discharge the Company and the members of the Company Group from any liability under the Specified Intercompany Agreements. Each Party shall, at the reasonable request of the other Party(ies), document an amendment or restatement of a Specified Intercompany Agreement (the initial draft of which will be prepared by the Company) as may be reasonably necessary to effectuate the foregoing. The Parties shall cooperate in good faith following the Distribution Time to identify and enter into (the initial draft of which will be prepared by the Company) any additional agreements, arrangements, commitments or understandings (the “Additional Intercompany Agreements”) reasonably necessary to fulfill the Specified Intercompany Agreement Purpose. The terms relating to the Specified Intercompany Agreements set forth in this paragraph shall apply to Additional Intercompany Agreements mutatis mutandis.”
