which its consent is required for termination. Notwithstanding anything to the contrary in this Agreement or in any release, termination, discharge or other document executed in connection herewith, indemnification and confidentiality obligations
contained in the XM-4 Transaction Agreements and those provisions and rights that survive termination in accordance with their terms shall continue and survive termination. The parties acknowledge and agree that (i) the payment described in
Section 2(a) constitutes payment in full of the principal of, interest and all other amounts payable with respect to the Notes, (ii) all amounts owed to the Indenture Trustee under the Indenture, under the Notes and under the Participation

that may not be able to be terminated by the sole action of the parties hereto.” To the extent a party hereto is not a party to each of such agreements, such party is only acting hereby with respect to those agreements to which it is a party or
with respect to which its consent is required for termination. Notwithstanding anything to the contrary in this Agreement or in any release, termination, discharge or other document executed in connection herewith, indemnification and
confidentiality obligations contained in the XM-4 Transaction Agreements and those provisions and rights that survive termination in accordance with their terms shall continue and survive termination. 
 (c) The termination of the XM-4 Transaction Agreements in this Section 3 shall not constitute a waiver of any right to indemnification under, or

Participant.

fees, costs and expenses (including attorneys’ fees) of the other parties hereto and of the Noteholders incurred in connection with the Offer, the negotiation, preparation, execution and delivery of this Agreement and the documents and

the Participation Agreement, that the Owner Participant and each of its representatives, consultants and agents reasonably promptly return to XM all Proprietary Information of XM in their possession (subject to any retention requirements pursuant to
Applicable Law and the other provisions of Section 13.01(d)). 
 8. Direction of Owner Trustee; Action as Assignee. The parties
hereto acknowledge that pursuant to Section 4.02 of the Trust Agreement the Owner Participant has directed, and the Owner Participant hereby directs, the Owner Trustee to execute, deliver and perform this Agreement, including both the actions
being taken on or about the date hereof and the actions (including those referred to in Section 4) to be taken after the date hereof. The parties hereto acknowledge that pursuant to Section 2(b) the Indenture Trustee has assigned, its
estate, right, title and interest in and to the Lease, Guarantee Agreement, Bill of Sale, Consent and Agreement, Purchase Agreement, Service Agreement and Telesat Agreement to the Owner Trustee, as provided for in Section 9.3 of the Indenture,
and the Owner Trustee hereby agrees and confirms that to the extent such assignment has occurred prior to the actions relating to releases of liens and security interests and terminations of agreements or rights hereunder by the Indenture Trustee,
the Owner Trustee is taking (or also taking) such actions. 
 9. Indenture Trustee Also Acting as Attorney-in-Fact. The parties hereto
acknowledge that pursuant to the Noteholder Instruction Letter contained in the Instruction and Letter of Transmittal (as defined in the Offer) the Indenture Trustee has been constituted and
