Agreement to Complete Restructuring and Consummate Concurso Plan and Chapter 11 Plan. From and after the date hereof and until the earlier of the (i) termination of this Agreement in accordance with the terms specified herein and (ii) Effective Date: (a) The Additional Supporting Holder agrees to vote (or, in the case of managed accounts, instruct the custodial agent to vote) all Existing Notes held or owned (directly or indirectly) by the Additional Supporting Holder to accept the Chapter 11 Plan promptly upon receipt of the Solicitation Materials (but in all events before any deadlines for submitting such votes). The Additional Supporting Holder may not revoke, withdraw or modify any ballot tendered in connection with a vote to accept the Chapter 11 Plan; provided, however, that if any term or condition of the Chapter 11 Plan is modified, amended or waived in any material respect such that a Supporting Holder shall have the right to revoke, withdraw or modify its vote to accept the Chapter 11 Plan under applicable law or otherwise, then the Additional Supporting 2 Holder shall have the right to revoke, withdraw, or modify its vote to accept the Chapter 11 Plan prior to the Effective Date. (b) The Additional Supporting Holder agrees that (i) it will not, directly or indirectly, execute, vote (or, in the case of managed accounts, instruct the custodial agent to vote) for, consent to, provide any support for, participate in the formulation of, or solicit or encourage others to formulate any bankruptcy plan, convenio concursal, restructuring, reorganization, liquidation or similar arrangement (in whatever jurisdiction proposed) for the Company or of any of its affiliates other than the Restructuring, the Concurso Plan, and the Chapter 11 Plan; (ii) it will not, directly or indirectly, object to, or otherwise commence any proceeding to oppose, the Restructuring or the Concurso Plan or Chapter 11 Plan and will not, directly or indirectly, take any action in opposition to, or that would unreasonably delay the consummation of, the Restructuring or the Concurso Plan or Chapter 11 Plan; (iii) it will support the Restructuring and approval of the Concurso Plan and the Chapter 11 Plan; (iv) if an FRN holder, it will not request (or support any other FRN holder or other party requesting) or otherwise file any motion or commence any action or proceeding, seeking adequate protection; (v) if an FRN holder, except as otherwise required to effect the Restructuring, it will not, directly or indirectly through the collateral trustee for the FRNs, take or cause to be taken, by exercise of rights under the stock trusts securing the guarantees of the FRNs, any shareholder action of the Company; and (vi) it will support the restructuring of Servicios Corporativos Satelitales, S.A. de C.V. (the "Servicios Restructuring") and, if an FRN holder, except as otherwise required to effect the Servicios Restructuring, it will not, directly or indirectly through the collateral trustee for the FRNs, take or cause to be taken, by exercise of rights under the stock trusts securing the guarantees of the FRNs, any shareholder action of Servicios; provided, however, that nothing in this Agreement shall require the Additional Supporting Holder to indemnify the indenture trustee for the FRNs or the HYBs or the collateral trustee for the FRNs. (c) The Additional Supporting Holder shall (x) forbear (and agrees not to give instructions to any applicable indenture trustee or agent or other person that are inconsistent with the terms and conditions of this Agreement) from the exercise of any rights, powers or remedies against the Company or any affiliate it may have (including the right to call a default or seek payment or any other relief in connection with any of the Existing Notes) under (a) the Existing Notes, (b) any applicable documents governing any of the Existing Notes, (c) any applicable law in connection with the Existing Notes and/or such documents or (d) the Concurso Proceeding and (y) not challenge or cause to be challenged the order entered by the Mexican Bankruptcy Court approving the Concurso Plan; provided, however, that this section 2(c) shall not apply to actions in furtherance of the Restructuring that are consistent with this Agreement and the Concurso Plan or the Chapter 11 Plan. Additionally, the Additional Supporting Holder will direct the indenture trustee for the FRNs and the HYBs and any collateral trustee for the FRNs, each as reasonably necessary and as applicable, to take actions in furtherance of the Restructuring, the Concurso Plan, and the Chapter 11 Plan; provided, further, that no direction shall be required if it involves indemnification by the Additional Supporting Holder of any party. 3. Transfer of Existing Notes; Acquisition of FRNs or HYBs. (a) The Additional Supporting Holder hereby agrees that it shall not Transfer any of the Existing Notes unless the transferee executes the Instrument of Accession attached 3 hereto as Exhibit B.

Upon the delivery of such executed Instrument of Accession, the Additional Supporting Holder shall have no further obligation or liability hereunder with respect to the transferred Existing Notes (and, in the case of a Transfer of all Existing Notes held by the Additional Supporting Holder, shall have no further obligation or liability hereunder whatsoever) other than for any default by the Additional Supporting Holder that occurred prior to the effectiveness of the Transfer. If the Additional Supporting Holder Transfers any Existing Notes without the transferee executing and delivering the Instrument of Accession to the Company in accordance with this section 3(a), the Transfer of such Existing Notes shall be deemed ineffective to transfer any right to accept or reject the Chapter 11 Plan, which right shall remain with and be exercised only by the Additional Supporting Holder. (b) In addition to the restrictions specified in Section 3(a), the Additional Supporting Holder, except if is not domiciled in the United States of America, hereby agrees that prior to delivery of its vote to accept the Chapter 11 Plan, it shall not, without the prior written consent of the Company (not to be unreasonably withheld), Transfer any Existing Note that is an FRN to a transferee unless the transferee is (x) a Person (as defined in the Bankruptcy Code) domiciled in the United States of America or with a place of business in the United States of America, (y) is a fund managed by a person domiciled in the United States of America or with a place of business in the United States of America or (z) already a holder of FRNs and is party to an agreement with the Company to support the Restructuring. (c) The Additional Supporting Holder further agrees that any and all FRNs or HYBs acquired by such Additional Supporting Holder following the date of this Agreement shall be subject to the terms and conditions of this Agreement and shall be deemed to be Existing Notes and subject to the same treatment as the Existing Notes held by such Additional Supporting Holder as of the date hereof. Notwithstanding anything contrary to the foregoing, if the Additional Supporting Holder acquires or disposes of any FRNs or HYBs after the date hereof, it shall promptly send a written notice to the Company and all other parties identified in Section 10 hereof, specifying the type, amount and/or number (as applicable) of FRNs or HYBs acquired or disposed of Notwithstanding the foregoing or anything in this Agreement to the contrary, no participation or other interest of the Additional Supporting Holder in FRNs held by or acquired from a Supporting FRN Holder in accordance with the terms and restrictions of the Restructuring Agreement (defined below) shall be subject to this Agreement. 4.
