It is understood and agreed that nothing in this Section 2.9 is intended to alter the priorities among Secured Parties belonging to different Classes as provided in Section 2.3.

All distributions and amounts in the event payable to the Collateral Trustee pursuant to this Agreement or any of the Secured Obligations shall be payable at the address of the Collateral Trustee set forth in Section 7.7.

SECTION 3.5 Powers of the Collateral Trustee.

(a) The Collateral Trustee is irrevocably authorized and empowered to enter into and perform its obligations and protect, perfect, exercise and enforce its interest, rights, powers and remedies under the Security Documents and applicable law and in equity and to act as set forth in this Article 3 or as requested in any lawful directions given to it from time to time in writing in respect of any matter by an Act of Required Debtholders (or an act of Required Junior Lien Debtholders to the extent provided for herein).

(b) Except as set forth herein, no Secured Debt Representative or holder of Secured Obligations will have any liability whatsoever for any act or omission of the Collateral Trustee.

SECTION 3.6 Protection of Collateral. The Collateral Trustee may from time to time, at its option, but shall not be obligated to, perform any act which Satmex or any Guarantor agrees hereunder to perform and which Satmex or such Guarantor shall fail to perform after being requested in writing so to perform (it being understood that no such request need be given after the occurrence and during the continuance of a Secured Debt Default) and the Collateral Trustee may, but shall not be obligated to, from time to time take any other action which the Collateral Trustee reasonably deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein.

SECTION 3.7 Documents and Communications. The Collateral Trustee will permit each Secured Debt Representative and each holder of Secured Obligations upon reasonable written notice from time to time to inspect and copy, at the cost and expense of the party requesting such copies, any and all Security Documents and other documents, notices, certificates, instructions or communications received by the Collateral Trustee in its capacity as such.

SECTION 3.8 For Sole and Exclusive Benefit of Holders of Secured Obligations.

29

SECTION 3.9 Additional Secured Debt.

(a) The Collateral Trustee will, as collateral trustee hereunder, perform its undertakings set forth in Section 3.1(a) with respect to each holder of Secured Obligations of a Series of Secured Debt that is issued or incurred after the date hereof that:

(1) holds Secured Obligations that are identified as Priority Lien Obligations or Junior Lien Debt in accordance with the procedures set forth in Section 3.8(b); and

(2) signs, through its designated Secured Debt Representative identified pursuant to Section 3.8(b), a Collateral Trust Joinder and delivers the same to the Collateral Trustee.

(b) Satmex will be permitted to designate as an additional holder of Secured Obligations hereunder each Person who is, or who becomes, the registered holder of Priority Lien Obligations or the registered holder of Junior Lien Debt incurred by Satmex after the date of this Agreement in accordance with the terms of all applicable Secured Debt Documents. Satmex may only effect such designation by delivering to the Collateral Trustee an Additional Secured Debt Designation stating:

(1) that Satmex intends to incur additional Secured Debt (“Additional Secured Debt”) which will either be (i) Priority Lien Obligations permitted by each applicable Secured Debt Document to be secured by a Priority Lien equally and ratably with all previously existing and future Priority Lien Obligations or (ii) Junior Lien Debt permitted by each applicable Secured Debt Document to be secured with a Junior Lien equally and ratably with all previously existing and future Junior Lien Debt;

(2) the name and address of the Secured Debt Representative for such series of Additional Secured Debt for purposes of Section 7.7.

(3) that Satmex and each Guarantor has duly authorized, executed (if applicable) and recorded (or caused to be recorded) in each appropriate governmental office all relevant filings and recordations to ensure that the Additional Secured Debt is secured by the Collateral in accordance with the Security Documents;

(4) that attached as Exhibit 1 to such Additional Secured Debt Designation is a Reaffirmation Agreement duly executed by Satmex and each Guarantor, which Reaffirmation Agreement shall be substantially in the form of Exhibit 1 to Exhibit A hereto; and

(5) that Satmex has caused a copy of the Additional Secured Debt Designation and the related Collateral Trust Joinder to be delivered to each then existing Secured Debt Representative.

Although Satmex shall be required to deliver a copy of each Additional Secured Debt Designation and each Collateral Trust Joinder to each then existing Secured Debt Representative, the failure to so deliver a copy of the Additional Secured Debt and/or Collateral Trust Joinder to any then existing Secured Debt Representatives shall not affect the status of such debt as Additional Secured Debt if the other requirements of this Section 3.8 are complied with. Each of the Collateral Trustee and the other then existing Secured Debt Representative shall have the right to receive from Satmex an Opinion of Counsel as to the Additional Secured Debt being secured by a valid and perfected security interest; provided, however, that such legal opinion or opinions need not address any collateral of a type or located in a jurisdiction not previously covered by any legal opinion delivered by or on behalf of Satmex. Notwithstanding the foregoing, nothing in this Agreement will be construed to allow Satmex or any Guarantor to incur additional Indebtedness unless otherwise permitted by the terms of all applicable Secured Debt Documents.

30

SECTION 3.10 Investments. (a) Unless a Secured Debt Default shall have occurred and be continuing, the Collateral Trustee shall invest and reinvest moneys deposited into a Collateral Proceeds Account at any time in Cash Equivalents as directed in writing by Satmex. All such investments of funds, the interest and income received thereon and the net proceeds realized on the sale or redemption thereof shall be as part of the Trust Estates. In no event shall the Collateral Trustee be liable for the selection of investments or for investment losses incurred thereon. The Collateral Trustee shall have no liability in respect of the losses incurred as a result of the liquidation of any investments prior to its stated maturity or the failure of Satmex, any Guarantor, or any Secured Party to provide timely written direction.

(b) The Collateral Trustee shall have no obligation to invest or reinvest the amounts deposited in the Collateral Proceeds Account if deposited with the Collateral Trustee after 11:00 a.m., New York time, on such day of deposit. Instructions received after 11:00 a.m., New York time, will be treated as if received on the following Business Day. Any proceeds, payments, income or other gain from investments in Cash Equivalents made in respect of funds in or credited to the Collateral Proceeds Account shall be credited to the Collateral Proceeds Account. Satmex shall be liable for any loss incurred on funds invested in any Cash Equivalents directed by it. Any interest or other income received on such investment and reinvestment of amounts in the Collateral Proceeds Account shall become part of the Collateral Proceeds Account and any losses incurred on such investment and reinvestment of the amounts in the Collateral Proceeds Account shall be debited against the amounts in the Collateral Proceeds Account. It is agreed and understood that the Collateral Trustee may earn fees associated with the Cash Equivalents in accordance with the terms of the Cash Equivalents. In no event shall the Collateral Trustee be deemed an investment manager or adviser in respect of any selection of Cash Equivalents hereunder. It is understood and agreed that the Collateral Trustee or its affiliates are permitted to receive additional compensation that could be deemed to be in the Collateral Trustee’s economic self-interest for (1) serving as investment adviser, administrator, shareholder servicing agent, custodian or sub-custodian with respect to certain of the Cash Equivalents, (2) using affiliates to effect transactions in certain Cash Equivalents and (3) effecting transactions in Cash Equivalents.

(3) as to a release of less than all or substantially all of Priority Liens on such Collateral, if (a) consent to release of that Collateral has been given by an Act of Required Debtholders, (b) such release is in connection with a transaction or circumstance that complies with Section 4.10 of the Indenture and is permitted by all of the other Security Documents at the time of such sale, transfer or other disposition, or (c) a Guarantor’s Guarantee is released under Section 11.05 of the Indenture; and

(2) the proposed instrument or instruments releasing such Lien as to such property in recordable form, if applicable; and

(3) with respect to Section 4.1(a)(1), an Opinion of Counsel that such release is permitted by Section 4.1(a)(1);

32

then the Collateral Trustee will promptly execute (with such acknowledgements and/or notarizations as are required) and deliver such release to Satmex or the applicable Guarantor on the date specified in such request for such release; provided that the Collateral Trustee shall have received the items required by this Section 4.1(b) on or prior to such specified date.

(c) The Collateral Trustee hereby agrees that in the case of any release pursuant to clause (2) of Section 4.1(a), if the terms of any such sale, transfer or other disposition require the payment of the purchase price to be contemporaneous with the delivery of the applicable release, then, at the written request of and at the expense of Satmex or the applicable Guarantor, the Collateral Trustee will either (A) be present at and deliver the release at the closing of such transaction or (B) deliver the release under customary escrow arrangements that permit such contemporaneous payment and delivery of the release.

SECTION 4.3 Collateral Trustee not Required to Serve, File or Record. The Collateral Trustee is not required to serve, file, register or record any instrument releasing or subordinating its Liens on any Collateral; provided, however, that if Satmex or any Guarantor shall make a written demand for the execution, if required, of a termination statement under Section 9-513(c) of the UCC, the Collateral Trustee shall comply with such written request of Satmex or such Guarantor to comply with the requirements of such UCC provision, if the applicable Secured Debt Representative(s) have confirmed in writing to the Collateral Trustee that the requirements of such UCC provisions have been satisfied.

SECTION 4.4 Release of Liens in Respect of Notes. The Collateral Trustee’s Priority Lien will no longer secure the Notes outstanding under the Indenture or any other Obligations under the Indenture, and the right of the holders of the Notes and such Obligations to the benefits and proceeds of the Collateral Trustee’s Priority Lien on the Collateral will terminate and be discharged upon receipt by the Collateral Trustee from the Trustee of written notice in the form of an Officers’ Certificate as to:

(1) satisfaction and discharge of the Indenture as set forth under Article 12 of the Indenture;

(2) a Legal Defeasance or Covenant Defeasance (each as defined under the Indenture) of the Notes as set forth under Article 8 of the Indenture;

(a) The Collateral Trustee may seek and may conclusively rely upon, and shall be fully protected from acting or refraining from acting in reliance upon, any judicial order or judgment, upon any advice, opinion or statement of legal counsel, independent consultants and other experts selected by it in good faith and upon any certification, instruction, notice, resolution, request, statement, bond, debenture, note, other evidence of indebtedness or other written document (whether in its original or facsimile form) or other writing delivered to it by (x) Satmex or any Guarantor in compliance with the provisions of this Agreement, (y) any Secured Debt Representative as to the holders of Secured Obligations for whom it acts, or (z) any other Person permitted to make such delivery in compliance with the provisions of this Agreement, in each case without being required to determine the authenticity thereof or the correctness of any fact stated therein or the propriety or validity of service thereof. The parties recognize that the accuracy and completeness of information supplied by the Collateral Trustee hereunder maybe dependent upon the accuracy and completeness of the information received by the Collateral Trustee in accordance with the preceding sentence.

To the extent an Officers’ Certificate or Opinion of Counsel is required or permitted under this Agreement to be delivered to the Collateral Trustee in respect of any matter, the Collateral Trustee may rely conclusively on Officers’ Certificate or Opinion of Counsel as to such matter and such Officers’ Certificate or Opinion of Counsel shall be full warranty and protection to the Collateral Trustee for any action taken, not taken, suffered or omitted by it under the provisions of this Agreement and the other Security Documents.

SECTION 5.10 Security or Indemnity in favor of the Collateral Trustee. The Collateral Trustee will not be required to take any action at the direction of any Priority Lien Representative or any holder of any Priority Lien Obligations or to advance or expend any of its own funds or otherwise incur any financial liability in the performance of its duties or the exercise of its powers or rights hereunder unless it has been provided with security or indemnity reasonably satisfactory to it against any and all liability or expense which may be incurred by it by reason of taking or continuing to take such action. None of the provisions contained in this Agreement shall in any event require the Collateral Trustee to perform, or be responsible for the manner or omission of performance of, any of the duties or obligations of the holders of Priority Liens, any Secured Debt Representative, Satmex, any Guarantor or any Person other than the Collateral Trustee.

SECTION 5.11 Rights of the Collateral Trustee. In the event of any conflict between any terms and provisions set forth in this Agreement and those set forth in any other Security Document, the terms and provisions of this Agreement shall supersede and control the terms and provisions of such other Security Document. In the event there is any bona fide, good faith disagreement between the other parties to this Agreement or any of the other Security Documents resulting in adverse claims being made in connection with Collateral held by the Collateral Trustee and the terms of this Agreement or any of the other Security Documents do not unambiguously mandate the action the Collateral Trustee is to take or not to take in connection therewith under the circumstances then existing, or the Collateral Trustee is in doubt as to what action it is required to take or not to take hereunder or under the other Security Documents, it will be entitled to refrain from taking any action (and will incur no liability for doing so) until directed otherwise in writing by a request signed jointly by the parties hereto entitled to give such direction or by order of a court of competent jurisdiction.

SECTION 5.12 Limitations on Duty of Collateral Trustee in Respect of Collateral.

(a) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Trustee will have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the Collateral. The Collateral Trustee will be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property (unless the Collateral Trustee is directed in writing in accordance with the terms hereof to treat the Collateral otherwise) and the Collateral Trustee will not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Trustee in good faith.

37

(b) Except as provided in Section 5.12(a), the Collateral Trustee will not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Collateral Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of Satmex or any Guarantor to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Collateral Trustee hereby disclaims any representation or warranty to the current and future holders of the Secured Obligations concerning the perfection of the security interests granted to it or in the value of any of the Collateral.

(c) Except as set forth herein or expressly instructed by any Secured Party, subject to Section 5.10, the Collateral Trustee shall have no obligation to give, execute, deliver, file, record, authorize or obtain any financing statements, notices, instruments, documents, agreements, consents or other papers as shall be necessary to create, preserve, perfect or validate the security interest granted pursuant to any Security Document or to enable the Collateral Trustee to exercise and enforce its rights hereunder with respect to such pledge and security interest, and the Collateral Trustee has no responsibility or liability (i) in connection with the acts or omissions of Satmex, any Guarantor or any Secured Party in respect of the foregoing or (ii) for or with respect to the legality, validity and enforceability of any security interest created in the Collateral or the perfection and priority of such security interest.

(d) Unless a Secured Debt Default has occurred, the Collateral Trustee shall be obligated to perform such duties and only such duties as are specifically set forth in this Agreement and the Security Documents, and no implied covenants or obligations shall be read into this Agreement or any Security Document against the Collateral Trustee. After the occurrence and during the continuation of a Secured Debt Default, the Collateral Trustee shall exercise the rights and powers vested in it by this Agreement and the Security Documents.

(e) No provision of this Agreement, any Secured Debt Document or any Security Document shall be deemed to impose any duty or obligation on the Collateral Trustee to perform any act or acts or exercise any right, power, duty or obligation conferred or imposed on it, in any jurisdiction in which it shall be illegal to perform any such act or acts or to exercise any such right, power, duty or obligation.

38

SECTION 5.13 Assumption of Rights, Not Assumption of Duties. Notwithstanding anything to the contrary contained herein:

(1) each of the parties thereto will remain liable under each of the Security Documents (other than this Agreement) to the extent set forth therein to perform all of their respective duties and obligations thereunder to the same extent as if this Agreement had not be executed;

(2) the exercise by the Collateral Trustee of any of its rights, remedies or powers hereunder will not release such parties from any of their respective duties or obligations under the other Security Documents; and

(3) the Collateral Trustee will not be obligated to perform any of the obligations or duties of any of the parties thereunder other than the Collateral Trustee.

SECTION 5.14 No Liability for Clean Up of Hazardous Materials. In the event that the Collateral Trustee is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any trust obligation for the benefit of another, which may cause the Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the Collateral Trustee to incur, or be exposed to, any environmental liability or any liability under any other federal, state or local law, the Collateral Trustee reserves the right, instead of taking such action, either to resign as Collateral Trustee or to arrange for the transfer of the title or control of the asset to a court appointed receiver. The Collateral Trustee will not be liable to any Person for any environmental liability or any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of the Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to any kind of discharge or release or threatened discharge or release of any hazardous materials into the environment.

ARTICLE 6. RESIGNATION AND REMOVAL OF THE COLLATERAL TRUSTEE

SECTION 6.1 Resignation or Removal of Collateral Trustee. Subject to the appointment of a successor Collateral Trustee as provided in Section 6.2 and the acceptance of such appointment by the successor Collateral Trustee:

(b) the Collateral Trustee may be removed at any time, with or without cause, by an Act of Required Debtholders.

SECTION 6.2 Appointment of Successor Collateral Trustee. Upon any such resignation or removal, a successor Collateral Trustee may be appointed by an Act of Required Debtholders. If no successor Collateral Trustee has been so appointed and accepted such appointment within 30 days after the predecessor Collateral Trustee gave notice of resignation or was removed, the retiring Collateral Trustee may (at the expense of Satmex), at its option, appoint a successor Collateral Trustee, or petition a court of competent jurisdiction for appointment of a successor Collateral Trustee, which must be a bank or trust company:

(1) authorized to exercise corporate trust powers;

(2) having a combined capital and surplus of at least $150,000,000;

39

(3) maintaining an office in New York, New York; and

(4) that is not a Secured Debt Representative.

The Collateral Trustee will fulfill its obligations hereunder until a successor Collateral Trustee meeting the requirements of this Section 6.2 has accepted its appointment as Collateral Trustee and the provisions of Section 6.3 have been satisfied. Notwithstanding resignation or replacement of the Collateral Trustee pursuant to this Section 6.2, the predecessor Collateral Trustee will remain entitled to enforce the immunities granted to it in Article 5 and Satmex and the Guarantor’s obligations under the provisions of Sections 7.10 and 7.11 shall continue for the benefit of the resigning or retiring Collateral Trustee. Within 30 days after such resignation or replacement, Satmex and the Guarantors agree to pay all compensation and fees and expenses which are due and payable to such retiring or replaced Collateral Trustee.

SECTION 6.3 Succession. When the Person so appointed as successor Collateral Trustee accepts such appointment:

(1) such Person will succeed to and become vested with all the rights, powers, privileges and duties of the predecessor Collateral Trustee, and the predecessor Collateral Trustee will be discharged from its duties and obligations hereunder; and

(2) the predecessor Collateral Trustee will (at the expense of Satmex) promptly execute all documents provided to it in order to transfer all Liens and collateral security and other property of the Trust Estates within its possession or control to the possession or control of the successor Collateral Trustee and will execute instruments and assignments as may be necessary or desirable or reasonably requested by the successor Collateral Trustee to transfer to the successor Collateral Trustee all Liens, interests, rights, powers and remedies of the predecessor Collateral Trustee in respect of the Security Documents or the Trust Estates.

The predecessor Collateral Trustee will not be held responsible or liable for any action or inaction of the successor Collateral Trustee.

SECTION 6.4 Merger, Conversion or Consolidation of Collateral Trustee. Any Person into which the Collateral Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Collateral Trustee shall be a party, or to which the Collateral Trustee has sold its corporate trust business substantially as a whole, or any Person succeeding to the business of the Collateral Trustee shall be the successor of the Collateral Trustee under this Agreement, the Security Documents and the Secured Debt Documents, without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto, except where an instrument of transfer or assignment is required by law to effect such succession, provided, that, anything herein to the contrary notwithstanding, such Person satisfies the eligibility requirements specified in clauses (1) through (4) of Section 6.2. Upon any such merger, conversion or consolidation, the Collateral Trustee shall have notified Satmex, each Priority Lien Representative and each Junior Lien Representative thereof in writing, provided that the failure to provide such notification shall not affect the succession of such successor Collateral Trustee under this Agreement, the Security Documents or and the Secured Debt Documents.

40

SECTION 6.5 Co-Collateral Trustee; Separate Collateral Trustee. (a) If at any time or times it shall be necessary or prudent in order to conform to any law of any jurisdiction in which any of the Collateral shall be located, or to avoid any violation of law or imposition on the Collateral Trustee of taxes by such jurisdiction not otherwise imposed on the Collateral Trustee, or the Collateral Trustee shall be advised by counsel, satisfactory to it, that it is necessary or prudent in the interest of the holders of Secured Debt, or by an Act of Required Debtholders shall request the Collateral Trustee and Satmex, or the Collateral Trustee shall deem it desirable for its own protection in the performance of its duties hereunder or under any Secured Debt Document, the Collateral Trustee and Satmex shall execute and deliver all instruments and agreements necessary or proper to constitute another bank or trust company, or one or more persons approved by the Collateral Trustee and, unless a Secured Debt Default shall have occurred and be continuing, Satmex, either to act as co-trustee or co-trustees or agent or bailee of all or any of the Collateral under this Agreement or under any of the Security Documents, jointly with the Collateral Trustee originally named herein or therein or any successor Collateral Trustee, or to act as separate trustee or trustees or agent or bailee of any of the Collateral. If Satmex shall not have joined in the execution of such instruments and agreements within 10 Business Days after it receives a written request from the Collateral Trustee to do so, or if a Secured Debt Default shall have occurred and be continuing, the Collateral Trustee may act under the foregoing provisions of this subsection without the concurrence of Satmex and execute and deliver such instruments and agreements on behalf of Satmex. Satmex hereby appoints the Collateral Trustee as its agent and attorney-in-fact to act for it under the foregoing provisions of this subsection in either of such contingencies.

(b) Every separate trustee and every co-trustee, other than any successor Collateral Trustee appointed pursuant to Section 6.2, shall, to the extent permitted by law, be appointed and act and be such, subject to the following provisions and conditions:

(i) all rights, powers, duties and obligations conferred upon the Collateral Trustee in respect of the custody, control and management of moneys, papers or securities shall be exercised solely by the Collateral Trustee or any agent appointed by the Collateral Trustee;

(ii) all rights, powers, duties and obligations conferred or imposed upon the Collateral Trustee hereunder and under the relevant Guarantee or Security Document shall be conferred or imposed and exercised or performed by the Collateral Trustee and such separate trustee or separate trustees or co-trustee or co-trustees, jointly, as shall be provided in the instrument appointing such separate trustee or separate trustees or co-trustee or co-trustees, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Collateral Trustee shall be incompetent or unqualified to perform such act or acts, or unless the performance of such act or acts would result in the imposition of any tax on the Collateral Trustee which would not be imposed absent such joint act or acts, in which event such rights, powers, duties and obligations shall be exercised and performed by such separate trustee or separate trustees or co-trustee or co-trustees;

41

(iii) no power given hereby or by the relevant Guarantee or Security Documents to, or which it is provided herein or therein may be exercised by, any such co-trustee or co-trustees or separate trustee or separate trustees, shall be exercised hereunder or thereunder by such co-trustee or co-trustees or separate trustee or separate trustees except jointly with, or with the consent in writing of, the Collateral Trustee, anything contained herein to the contrary notwithstanding;

(iv) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder, and

(v) Satmex and the Collateral Trustee, at any time by an instrument in writing executed by them jointly, may (and, at the direction of an Act of Required Debtholders, shall) accept the resignation of or remove any such separate trustee or co-trustee and, in that case by an instrument in writing executed by them jointly, may appoint a successor to such separate trustee or co-trustee, as the case may be, anything contained herein to the contrary notwithstanding. If Satmex shall not have joined in the execution of any such instrument within 10 Business Days after it receives a written request from the Collateral Trustee to do so, or if a Secured Debt Default shall have occurred and be continuing, the Collateral Trustee shall have the power to (and, at the direction of an Act of Required Debtholders, shall) accept the resignation of or remove any such separate trustee or co-trustee and to appoint a successor without the concurrence of Satmex, Satmex hereby appointing the Collateral Trustee its agent and attorney to act for it in such connection in such contingency. If the Collateral Trustee shall have appointed a separate trustee or separate trustees or co-trustee or co-trustees as above provided, the Collateral Trustee may at any time, by an instrument in writing, accept the resignation of or remove any such separate trustee or co-trustee and the successor to any such separate trustee or co-trustee shall be appointed by Satmex and the Collateral Trustee, or by the Collateral Trustee alone pursuant to this subsection.

ARTICLE 7. MISCELLANEOUS PROVISIONS

SECTION 7.1 Amendment.

(a) No amendment or supplement to the provisions of any Security Document (including this Agreement) will be effective without the approval of the Collateral Trustee acting as directed in writing by an Act of Required Debtholders, except that:

(1) any amendment or supplement that has the effect solely of (a) adding or maintaining Collateral (including providing for entering into additional, supplemental or replacement Security Documents), securing additional Secured Debt that was otherwise permitted by the terms of the Secured Debt Documents to be secured by the Collateral or preserving, perfecting or establishing the priority of the Liens thereon or the rights of the Collateral Trustee therein; (b) curing any ambiguity, omission, mistake, defect or inconsistency; (c) providing for the assumption of any Grantor’s obligations under any Secured Debt

(2) no amendment or supplement that reduces, impairs or adversely affects the right of any holder of Secured Obligations:

(A) to vote its outstanding Secured Debt as to any matter described as subject to an Act of Required Debtholders or an act of Required Junior Lien Debtholders (or amends the provisions of this clause (2) or the definition of “Act of Required Debtholders” or “Required Junior Lien Debtholders”),

(B) to share in the order of application described in Section 3.4 in the proceeds of enforcement of or realization on any Collateral that has not been released in accordance with the provisions described in Section 4.1, or

(C) to require that Liens securing Secured Obligations be released only as set forth in the provisions described in Section 4.1,

will become effective without the consent of the requisite percentage or number of holders of each Series of Secured Debt so affected under the applicable Secured Debt Documents; and

(3) no amendment or supplement that imposes any obligation upon the Collateral Trustee or any Secured Debt Representative or adversely affects the rights of the Collateral Trustee or any Secured Debt Representative, respectively, in its capacity as such will become effective without the consent of the Collateral Trustee or such Secured Debt Representative, respectively.

(4) any amendment or supplement to the provisions of the Security Documents that releases Collateral will be effective only in accordance with the requirements set forth in the applicable Secured Debt Documents referenced above in Section 4.1 Any amendment or supplement that results in the Collateral Trustee’s Liens upon the Collateral no longer securing the Notes and the other Obligations under the Indenture may only be effected in accordance with the provisions described above in Section 4.4.

43

(b) The Collateral Trustee will not enter into any amendment or supplement unless it has received an Officers’ Certificate to the effect that such amendment or supplement will not result in a breach of any provision or covenant contained in any of the Secured Debt Documents. Prior to executing any amendment or supplement pursuant to this Section 7.1, the Collateral Trustee shall receive an Opinion of Counsel of Satmex to the effect that the execution of such document is authorized or permitted hereunder, and with respect to amendments adding Collateral, an Opinion of Counsel of Satmex addressing customary creation and perfection, and if such additional Collateral consists of Equity Interests of any Person which Equity Interests constitute certificated securities, priority matters with respect to such additional Collateral (which opinion may be subject to customary assumptions and qualifications).

(c) The holders of Junior Lien Obligations and the Junior Lien Representatives agree that each Security Document that secures Junior Lien Obligations (but not also securing Priority Lien Obligations) will include the following or similar language:

“Notwithstanding anything herein to the contrary, the lien and security interest granted to the Collateral Trustee pursuant to this Agreement and the exercise of any right or remedy by such Collateral Trustee hereunder are subject to the provisions of the Collateral Trust Agreement, dated as of May 26, 2011, among Satélites Mexicanos, S.A. de C.V., the Guarantors from time to time party thereto, Wilmington Trust FSB, as Trustee under the Indenture (as defined therein) and ▇▇▇▇▇ Fargo Bank, National Association, as Collateral Trustee (as amended, supplemented, amended and restated or otherwise modified and in effect from time to time, the “Collateral Trust Agreement”). In the event of any conflict between the terms of the Collateral Trust Agreement and this Agreement, the terms of the Collateral Trust Agreement will govern.”

; provided, however, that if the jurisdiction in which any such Junior Lien Document will be filed prohibits the inclusion of the language above or would prevent a document containing such language from being recorded, the Junior Lien Representatives and the Priority Lien Representatives agree, prior to such Junior Lien Document being entered into, to negotiate in good faith replacement language stating that the lien and security interest granted under such Junior Lien Document is subject to the provisions of this Agreement.

SECTION 7.2 Voting. In connection with any matter under this Agreement requiring a vote of holders of Secured Obligations, each Series of Secured Debt will cast its votes in accordance with the Secured Debt Documents governing such Series of Secured Debt by a notice delivered by the applicable Secured Debt Representative to the Collateral Trustee. Hedging Obligations and Banking Product Obligations will not be considered for purposes of voting by holders of Secured Obligations under this Agreement unless the only Secured Obligations outstanding are Hedging Obligations or Banking Product Obligations and documents evidencing such Hedging Obligations and Banking Product Obligations that are equally and ratably secured with the other Secured Obligations expressly provide that such Hedging Obligations and Banking Product Obligations remain secured by the Collateral when they are the only Secured Obligations remaining. The amount of Secured Obligations to be voted by a Series of Secured Debt will equal (1) the

44

aggregate principal amount of Secured Debt held by such Series of Secured Debt (including, if provided for in the applicable Secured Debt Document, outstanding letters of credit whether or not then available or drawn), plus (2) if provided for in the applicable Secured Debt Document, the aggregate principal amount of unfunded commitments to extend credit which, when funded, would constitute Indebtedness of such Series of Secured Debt. Following and in accordance with the outcome of the applicable vote under its Secured Debt Documents, the Secured Debt Representative of each Series of Secured Debt will vote the total amount of Secured Debt under that Series of Secured Debt as a block in respect of any vote under this Agreement and the Collateral Trustee shall be entitled to rely conclusively without further investigation on such block vote of the Secured Debt Representatives and shall not be held responsible for the exercise of any such voting rights described herein.

SECTION 7.3 Further Assurances; Insurance.

(a) Each of the Grantors will do or cause to be done all acts and things that may be required, or that the Collateral Trustee when acting in accordance with an Act of Required Debtholders, from time to time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the holders of Secured Obligations, duly created and enforceable and perfected Liens upon the Collateral, in each case, as contemplated by, and with the Lien priority required under, the Secured Debt Documents. Without limiting the foregoing, to the extent any security interest in the Collateral cannot be perfected on or prior to the date hereof, after the use of all commercially reasonable efforts (other than any Collateral the security interest in which may be perfected by the filing of a UCC financing statement or other filings or registrations under any Mexican public registries or the delivery of stock certificates), Satmex and each of the Guarantors will cause all such security interests to be perfected (to the extent required by the Security Documents) on or prior to the date that is 90 days after the date hereof. To the extent that any such security interests are perfected subsequently, Satmex will be deemed to have satisfied its obligations with respect thereto and any default or event of default under any Secured Debt Document with respect thereto shall be deemed to have been cured.

(b) Satmex and the other Grantors will:

(1) keep their properties insured as is customary with companies in the same or similar businesses and industry by financially sound and reputable insurers;

(2) maintain such other insurance, to such extent and against such risks (and with such deductibles, retentions and exclusions), including fire and other risks insured against, as is customary with companies in the same or similar businesses and industry, including public liability insurance against claims for personal injury or death or property damage occurring upon, in, about or in connection with the use of any properties owned, occupied or controlled by them;

(3) maintain such other insurance as may be required by law; and

45

(4) maintain such other insurance as may be required by the Indenture and the Security Documents, if any, to the extent such insurance is available on commercially reasonable terms.

(c) Within thirty (30) days following any date on which Satmex is required or permitted to obtain insurance pursuant to Section 4.20 of the Indenture, Satmex shall deliver to the Collateral Trustee an insurance certificate certifying the amount of insurance then carried and in full force and effect. In addition, Satmex shall cause to be delivered to the Collateral Trustee no less than once each year an insurance certificate setting forth the amount of insurance then carried and in full force and effect, which insurance certificate shall entitle the Collateral Trustee to: (y) notice of any claim in excess of $1.0 million under any such insurance policy; and (z) at least thirty (30) days’ notice from the provider of such insurance prior to the cancellation of any such insurance.

(d) Satmex or the applicable Grantor shall use its reasonable best efforts to provide evidence that (x) the Collateral Trustee, on behalf of the Secured Parties, is named as additional insured with a waiver of subrogation on all insurance policies of Satmex and the other Grantors and (y) the Collateral Trustee, on behalf of the Secured Parties, is named as loss payee, with 30 days’ notice of cancellation or material change, on all property and casualty insurance policies of Satmex and the other Grantors, in each case, subject to the limitations set forth in the Security Documents and the Indenture.

(e) Upon the request of the Collateral Trustee and with reasonable notice (except after the occurrence and during the continuation of a Secured Debt Default), Satmex and the Guarantors will permit the Collateral Trustee or any of its agents or representatives, at reasonable times and intervals upon reasonable prior notice, to visit their offices and sites and inspect any of the Collateral and to discuss matters relating to the Collateral with their respective officers and independent public accountants. Satmex and the Guarantors shall, at any reasonable time and from time to time upon reasonable prior notice, permit the Collateral Trustee or any of its agents or representatives to examine and make copies of and abstracts from the records and books of account of Satmex and the Guarantors and their Subsidiaries, all at Satmex’s expense.

(f) Without limiting the foregoing, substantially concurrently with the acquisition by any Grantor of any assets that would constitute Collateral, such Grantor shall:

(1) take such other actions as shall be necessary or (in the reasonable opinion of any Secured Debt Representative) desirable to perfect and protect the Collateral Trustee’s security interest in such assets or property for the benefit of the current and future holders of the Secured Obligations, including without limitation, and to the extent applicable, the execution of additional Security Documents (or supplements or joinders thereto); the filing and/or recordation of Uniform Commercial Code financing statements, filings before the applicable Mexican registries, and other filings; the delivery of stock certificates endorsed in pledge or with accompanying stock powers, as the case may be; intellectual property security agreements to be filed with the United States Patent & Trademark Office and the United States Copyright Office and/or the Mexican Institute of Industrial Property (Instituto Mexicano de la Propiedad Industrial); mortgages; landlord waivers; control agreements; evidence of title insurance, flood insurance and surveys and other assurances and instruments (or, in each of the foregoing cases, the applicable foreign equivalent); and

46

(2) promptly deliver to the Collateral Trustee Opinions of Counsel, subject to customary qualifications, assumptions and exclusions, relating to the creation, validity and perfection of security interests relating to any material assets or property with a book value or fair market value in excess of $2,000,000.

(g) Satmex shall deliver to the Collateral Trustee within ninety days after the end of each fiscal year, a copy of the Officers’ Certificate required to be delivered to the Trustee pursuant to Section 4.04 of the Indenture, which Officers’ Certificate will include a certification that either (i) (x) such action has been taken with respect to the recordings, registrations, filings, re-recordings, re-registrations and refilings of the Security Documents (other than relating to mortgages, deeds of trust and similar Security Documents) and all financing statements, continuation statements and other instruments of further assurance as are necessary to maintain the perfected Liens under applicable law in those items of Collateral constituting the Senior Trust Estate and the Junior Trust Estate that can be perfected by the filing, recordings or registrations (other than relating to mortgages, deeds of trust and similar Security Documents) and reciting with respect to such Liens on and security interests in such Collateral the details of such action or referring to prior Officers’ Certificates in which such details are given, and (y) based on relevant laws as in effect on the date of such Officers’ Certificate, all financing statements, continuation statements, and other documents (other than relating to mortgages, deeds of trust and similar Security Documents) have been executed and filed that are necessary, as of such date and during the succeeding 12 months, fully to maintain the perfection of the security interests of the Collateral Trustee in the Collateral constituting the Senior Trust Estate and the Junior Trust Estate and under the Security Documents (other than relating to mortgages, deeds of trust and similar Security Documents) with respect to such Collateral; provided that if there is a required filing of a continuation statement or other instrument (other than relating to mortgages, deeds of trust and similar Security Documents) within such 12 month period and such continuation statement or other instrument is not effective if filed at the time of the delivery of such Officers’ Certificate, such Officers’ Certificate may so state and in that case Satmex shall cause a continuation statement or other instrument to be timely filed so as to maintain such Liens and security interests securing Priority Lien Obligations and Junior Lien Obligations shall provide a further Officers’ Certificate to the effect of this clause (i) upon the filing of the relevant continuation statement or other instrument; or (ii) no such action is necessary to maintain such Liens or security interests.

SECTION 7.4 Perfection of Junior Trust Estate.

Solely for purposes of perfecting the Liens of the Collateral Trustee in its capacity as agent of the holders of Junior Lien Obligations and the Junior Lien Representatives in any portion of the Junior Trust Estate in the possession or control of the Collateral Trustee (or its agents or bailees) as part of the Senior Trust Estate including, without limitation, any instruments, goods, negotiable documents, tangible chattel paper, certificated securities, securities accounts or money, the Collateral Trustee, the holders of Priority Lien Obligations and the Priority Lien Representatives hereby acknowledge that the Collateral Trustee also holds such property as

47

gratuitous bailee for the benefit of the holders of Junior Lien Obligations and the Junior Lien Representatives (such bailment being intended, among other things, to satisfy the requirements of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the UCC). Solely with respect to any deposit accounts under the control (within the meaning of Section 9-104 of the UCC) the Collateral Trustee in its capacity as agent of the holders of the Priority Lien Obligations agrees to also hold control over such deposit accounts as gratuitous agent for the benefit of the holders of Junior Lien Obligations and the Junior Lien Representatives.

SECTION 7.5 Successors and Assigns.

(a) Except as set forth herein, the Collateral Trustee may not, in its capacity as such, assign any of its duties or rights hereunder, and any attempted assignment of any such duties or rights will be null and void. All obligations of the Collateral Trustee hereunder will inure to the sole and exclusive benefit of, and be enforceable by, each Secured Debt Representative and each current and future holder of Secured Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

(b) Neither Satmex nor any Guarantor may delegate any of its duties or assign any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of Satmex and the Guarantors hereunder will inure to the sole and exclusive benefit of, and be enforceable by, the Collateral Trustee, each Secured Debt Representative and each current and future holder of Secured Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

SECTION 7.6 Delay and Waiver. No failure to exercise, no course of dealing with respect to the exercise of, and no delay in exercising, any right, power or remedy arising under this Agreement or any of the other Security Documents will impair any such right, power or remedy or operate as a waiver thereof. No single or partial exercise of any such right, power or remedy will preclude any other or future exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law.

SECTION 7.11 Indemnity.

(a) Satmex and the Guarantors jointly and severally agree to defend, indemnify, pay and hold harmless the Collateral Trustee and its Affiliates and each and all of the directors, officers, partners, trustees, employees, attorneys and agents, and (in each case) their respective heirs, representatives, successors and assigns (each of the foregoing, an “Indemnitee”) from and against any and all Indemnified Liabilities; provided, no Indemnitee will be entitled to indemnification hereunder with respect to any Indemnified Liability to the extent such Indemnified Liability is found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence, willful misconduct or bad faith of such Indemnitee.

(b) All amounts due under this Section 7.11 will be payable upon demand.

(c) Satmex and the Guarantors will never assert any claim against any Indemnitee, on any theory of liability, for any lost profits or special, indirect or consequential damages or (to the fullest extent a claim for punitive damages may lawfully be waived) any punitive damages arising out of, in connection with, or as a result of, this Agreement or any other Secured Debt Document or any agreement or instrument or transaction contemplated hereby or relating in any respect to any Indemnified Liability, and Satmex and each of the Guarantors hereby forever waives, releases and agrees not to ▇▇▇ upon any claim for any such lost profits or special, indirect, consequential or (to the fullest extent lawful) punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor.

(d) The agreements in this Section 7.11 will survive repayment of all other Secured Obligations, any termination of this Agreement and the removal or resignation of the Collateral Trustee.

(f) When the Collateral Trustee incurs expenses or renders services after a Secured Debt Default occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

(g) All indemnities to be paid under this Agreement, shall be payable immediately when due in U.S. dollars (the “Dollars”) in the full amount due, without deduction for any variation in any Rate of Exchange (as defined below). Satmex and the Guarantors agrees to indemnify the Collateral Trustee against any losses incurred by such the Collateral Trustee as a result of any judgment or order being given or made for the amount due hereunder and such judgment or order being expressed and paid in a currency (the “Judgment Currency”) other than Dollars and as a result of any variation as between (i) the rate of exchange at which the dollar amount is converted into Judgment Currency for the purpose of such judgment or order, and (ii) the Rate of Exchange at which the Collateral Trustee is then able to purchase Dollars with the amount of the Judgment Currency actually received by the Collateral Trustee. The indemnity set forth in this paragraph shall constitute a separate and independent obligation of Satmex and the Guarantors and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “Rate of Exchange” means the rate at which the Collateral Trustee is able to purchase Dollars with the Judgment Currency on the foreign exchange market on the relevant date and shall include any premiums and other reasonable costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

SECTION 7.16 Consent to Jurisdiction. All judicial proceedings brought against any party hereto arising out of or relating to this Agreement shall be brought in any state or federal court of competent jurisdiction in the State, County and City of New York and the parties hereto hereby expressly and irrevocably submit to the jurisdiction of any state or federal court in the State, County and City of New York, and hereby expressly and irrevocably waives their rights to any other jurisdiction that may apply by virtue of their present or future domiciles or for any other reason. By executing and delivering this Agreement, each Grantor, for itself and in connection with its properties, irrevocably:

(1) accepts generally and unconditionally the jurisdiction and venue of such courts;

(2) waives any defense of forum non conveniens;

(3) agrees that service of all process in any such proceeding in any such court may be made by registered or certified mail, return receipt requested, to such party at its address provided in accordance with Section 7.7;

(4) agrees that service as provided in clause (3) above is sufficient to confer personal jurisdiction over such party in any such proceeding in any such court and otherwise constitutes effective and binding service in every respect; and

(5) agrees each party hereto retains the right to serve process in any other manner permitted by law.

52

SECTION 7.17 Waiver of Jury Trial. Each party to this Agreement waives its rights to a jury trial of any claim or cause of action based upon or arising under this Agreement or any of the other Security Documents or any dealings between them relating to the subject matter of this Agreement or the intents and purposes of the other Security Documents. The scope of this waiver is intended to be all-encompassing of any and all disputes that may be filed in any court and that relate to the subject matter of this Agreement and the other Security Documents, including contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each party to this Agreement acknowledges that this waiver is a material inducement to enter into a business relationship, that each party hereto has already relied on this waiver in entering into this Agreement, and that each party hereto will continue to rely on this waiver in its related future dealings. Each party hereto further warrants and represents that it has reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its jury trial rights following consultation with legal counsel. This waiver is irrevocable, meaning that it may not be modified either orally or in writing (other than by a mutual written waiver specifically referring to this Section 7.17 and executed by each of the parties hereto), and this waiver will apply to any subsequent amendments, renewals, supplements or modifications of or to this Agreement or any of the other Security Documents or to any other documents or agreements relating thereto. In the event of litigation, this Agreement may be filed as a written consent to a trial by the court.

SECTION 7.18 Counterparts; Electronic Signatures. This Agreement may be executed in any number of counterparts (including by facsimile or other electronic transmission), each of which when so executed and delivered will be deemed an original, but all such counterparts together will constitute but one and the same instrument.

The electronic copy of the executed Agreement and any Collateral Trust Joinder is and shall be deemed an original signature

SECTION 7.19 Effectiveness. This Agreement will become effective upon the execution of a counterpart hereof by each of the parties hereto and receipt by each party of written notification of such execution and written or telephonic authorization of delivery thereof.

Satmex will cause each Person that hereafter becomes a Guarantor or is required by any Secured Debt Document to become a party to this Agreement to become a party to this Agreement, for all purposes of this Agreement, by causing such Person to execute and deliver to the Collateral Trustee a Collateral Trust Joinder, whereupon such Person will be bound by the terms hereof to the same extent as if it had executed and delivered this Agreement as of the date hereof. Satmex shall promptly provide each Secured Debt Representative with a copy of each Collateral Trust Joinder executed and delivered pursuant to this Section 7.20; provided, however, that the failure to so deliver a copy of the Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the inclusion of such Person as a Guarantor if the other requirements of this Section 7.20 are complied with.

53

SECTION 7.21 Continuing Nature of this Agreement. This Agreement, including the subordination provisions hereof, will be reinstated if at any time any payment or distribution in respect of any of the Priority Lien Obligations is rescinded or must otherwise be returned in an Insolvency, Concurso Mercantil, Quiebra or Liquidation Proceeding or otherwise by any holder of Priority Lien Obligations or Priority Lien Representative or any representative of any such party (whether by demand, settlement, litigation or otherwise). In the event that all or any part of a payment or distribution made with respect to the Priority Lien Obligations is recovered from any holder of Priority Lien Obligations or any Priority Lien Representative in an Insolvency, Concurso Mercantil, Quiebra or Liquidation Proceeding or otherwise, such payment or distribution received by any holder of Junior Lien Obligations or Junior Lien Representative with respect to the Junior Lien Obligations from the proceeds of any Collateral or any title insurance policy required by any real property mortgage at any time after the date of the payment or distribution that is so recovered, whether pursuant to a right of subrogation or otherwise, that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may be, will forthwith deliver the same to the Collateral Trustee, for the account of the holders of the Priority Lien Obligations and other Obligations secured by a Permitted Prior Lien, to be applied in accordance with Section 3.4. Until so delivered, such proceeds will be held by that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may be, for the benefit of the holders of the Priority Lien Obligations and other Obligations secured by a Permitted Prior Lien.

SECTION 7.22 Insolvency. The Parties acknowledge that this Agreement is a “subordination agreement” under section 510(a) of Title 11 of the United States Code entitled “Bankruptcy,” as now and hereafter in effect, or any successor statute, which will be effective before, during and after the commencement of an Insolvency, Concurso Mercantil, Quiebra or Liquidation Proceeding. All references in this Agreement to any Grantor will include such Person as a debtor-in-possession and any receiver or trustee for such Person in an Insolvency, Concurso Mercantil, Quiebra or Liquidation Proceeding. This Agreement will be applicable both before and after the commencement of any Insolvency, Concurso Mercantil, Quiebra or Liquidation Proceeding by or against any Grantor. The relative rights, as provided for in this Agreement, will continue after the commencement of any such Insolvency, Concurso Mercantil, Quiebra or Liquidation Proceeding on the same basis as prior to the date of the commencement of any such case, as provided in this Agreement.

SECTION 7.23 Rights and Immunities of Secured Debt Representatives. The Trustee will be entitled to all of the rights, protections, immunities and indemnities set forth in the Indenture and any future Secured Debt Representative will be entitled to all of the rights, protections, immunities and indemnities set forth in the credit agreement, indenture or other agreement governing the applicable Secured Debt with respect to which such Person will act as representative, in each case as if specifically set forth herein.
