(e) The Collateral Trustee shall promptly notify Satmex and the Indenture Trustee upon receipt of any Notice of Default or Notice of Cancellation of Enforcement and shall provide Satmex and the Indenture Trustee with a copy of any such Notice of Default or Notice of Cancellation of Enforcement, provided, however, that any failure of the Collateral Trustee to comply with this Section 3.1(e) shall have no effect on the validity or effectiveness of any Notice of Default, Enforcement Period, or Notice of Cancellation of Enforcement and shall not impair any of the rights, powers, and remedies of the Collateral Trustee, Indenture Trustee, or First Priority Holders under this Trust Agreement or any other First Priority Document.

(f) During an Enforcement Period, the Collateral Trustee may (but in the absence of direction from the Requisite First Priority Holders shall not be required to) take any action to exercise any remedies that are (i) permitted under any of the First Priority Documents or applicable law, and (ii) not inconsistent with any written direction given to the Collateral Trustee by the Requisite First Priority Holders under Section 3.5(b).

3.6 Remedies Not Exclusive.

(a) No remedy conferred upon or reserved to the Collateral Trustee herein or in any First Priority Guarantee or First Priority Security Document is intended to be exclusive of any other remedy or remedies, but every such remedy shall be cumulative and shall be in addition to every other remedy conferred herein, in any First Priority Guarantee or in any First Priority Security Document or now or hereafter existing at law or in equity or by statute.

(b) No delay by the Collateral Trustee in exercising or failure by the Collateral Trustee to exercise any right, remedy or power hereunder or under any First Priority Guarantee or First Priority Security Document shall impair any such right, remedy or power or shall be construed to be a waiver thereof or acquiescence therein, and every right, power and remedy given to the Collateral Trustee under this Trust Agreement, any First Priority Guarantee or any First Priority Security Document may be exercised from time to time and as often as may be deemed expedient by the Collateral Trustee or the Requisite First Priority Holders.

(c) If the Collateral Trustee shall have proceeded to enforce any right, remedy or power under this Trust Agreement, any First Priority Guarantee or any First Priority Security Document, such enforcement to be pursuant to the directions of the Requisite First Priority Holders and the proceeding for the enforcement thereof shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Trustee, then Satmex, the Collateral Trustee and the Secured Parties shall, subject to any effect of or determination in such proceeding, severally and respectively be restored to their former positions and rights hereunder or thereunder with respect to the Trust Estate and in all other respects, and thereafter all rights, remedies and powers of the Collateral Trustee shall continue as though no such proceeding had been taken.

(d) All rights of action and of asserting claims upon or under this Trust Agreement, the First Priority Guarantees and the First Priority Security Documents may, to the extent permitted by applicable law, be enforced by the Collateral Trustee without the possession of any First Priority Document or instrument evidencing any First Priority Obligation or the production thereof at any trial or other proceeding relative thereto, and any suit or proceeding instituted by the Collateral Trustee shall be, subject to subsections 8.5(c) and 8.10(b)(ii), brought in its name as Collateral Trustee and any recovery of judgment shall be held as part of the Trust Estate.

First Priority Security Document and waives, to the extent it may lawfully do so, all benefit or advantage of all such laws, and Satmex hereby covenants, to the extent it may lawfully do so, that it will not hinder, delay or impede the execution of any power granted to the Collateral Trustee in this Trust Agreement, any First Priority Guarantee or any First Priority Security Document but will suffer and permit the execution of every such power as though no such law were in force.

(b) Each of Satmex and the First Priority Guarantors, to the extent it may lawfully do so, on behalf of itself and all who may claim through or under it, including, without limitation, any and all subsequent creditors, vendees, assignees and lienors, (i) waives and releases all rights to demand or to have any marshalling of the First Priority Collateral upon any sale, whether made under any power of sale granted herein or in any First Priority Security Document or pursuant to judicial proceedings or upon any foreclosure or any enforcement of this Trust Agreement or any First Priority Security Document and (ii) consents and agrees that all the First Priority Collateral may at any such sale be offered and sold as an entirety.

SECTION 4
COLLATERAL ACCOUNT; DISTRIBUTIONS

4.1 The Collateral Account.

(a) On the Effective Date there shall be established and, at all times thereafter until the trusts created by this Trust Agreement shall have terminated, there shall be maintained with the Collateral Trustee at the U.S. office of the Collateral Trustee’s corporate trust division, a collateral account, in the name of the Collateral Trustee which shall be entitled the “Satmex Collateral Account” (the “Collateral Account”). All cash deposits, monies and proceeds of First Priority Collateral required to be held or otherwise received by the Collateral Trustee pursuant hereto or pursuant to any First Priority Document or otherwise shall be deposited in the

Collateral Account and held as part of the Trust Estate. The Collateral Account shall be subdivided into two sub-accounts, designated as the “Enforcement Proceeds Sub-Account” and the “First Priority Collateral Trustee Segregated Sub-Account” (each, a “Sub-Account,” all of which shall be non-interest bearing trust accounts (except to the extent invested in Cash Equivalents)).

(b) All cash deposits, monies, and proceeds of First Priority Collateral which are required by this Trust Agreement or any First Priority Document to be delivered to the Collateral Trustee or which are received by the Collateral Trustee or any agent or nominee of the Collateral Trustee in respect of the First Priority Collateral or the First Priority Guarantees, whether in connection with the exercise of the remedies provided in this Trust Agreement, any First Priority Guarantee or any First Priority Security Document or otherwise, while an Enforcement Period is in effect, shall be deposited in the Enforcement Proceeds Sub-Account and, in each case, held by the Collateral Trustee as part of the Trust Estate and applied in accordance with the terms of this Trust Agreement. Upon the termination of any Enforcement Period pursuant to subsection 3.1(c), the Collateral Trustee shall (subject to subsection 4.4) cause all funds on deposit in the Enforcement Proceeds Sub-Account, together with all interest and income on such amounts, to be deposited in the First Priority Collateral Trustee Segregated Sub-Account for application in accordance with the terms of Section 4 hereof and for use by Satmex in accordance with Section 4.35(b) of the First Priority Indenture.

(c) All moneys constituting First Priority Collateral Trustee Segregated Account Proceeds which are delivered to the Collateral Trustee pursuant to Section 3.2 and 4.35 of the First Priority Indenture or otherwise, while an Enforcement Period is not in effect, shall be deposited in the First Priority Collateral Trustee Segregated Sub-Account and held by the Collateral Trustee as part of the Trust Estate and applied in accordance with Sections 3.2 and 4.35 of the First Priority Indenture. Upon the receipt by the Collateral Trustee of a Notice of Default, all amounts on deposit in the First Priority Collateral Trustee Segregated Sub-Account shall automatically be deemed to be held in, and shall be transferred to the Enforcement Proceeds Sub-Account; provided, that all amounts so transferred from the First Priority Collateral Trustee Segregated Sub-Account to the Enforcement Proceeds Sub-Account, together with all interest and income on such amounts, shall be returned to the First Priority Collateral Trustee Segregated Sub-Account under the circumstances set forth in subsection 4.1(b).

(d) Satmex may, by delivery to the Collateral Trustee of a Proceeds Release Request, at any time, request a release of funds from the First Priority Collateral Trustee Segregated Sub-Account for any use in the aggregate amount permitted by Sections 3.2 and 4.35 of the First Priority Indenture. For all purposes under the Trust Agreement and otherwise, to be effective, each Proceeds Release Request (a) shall specify (i) the amount of funds to be released, (ii) the date of the requested release, (iii) the purpose for which Satmex expects to use such funds, (iv) the investments to be liquidated to provide cash to make such release, and (v) the wire instructions for the transfer of such funds and (b) shall be accompanied by a certificate of a Responsible Officer to the effect that such requested release of funds and proposed use thereof will not violate any First Priority Document and that no default or Event of Default has occurred and is continuing under any First Priority Document. If no Enforcement Period is in effect and no default or Event of Default has occurred and is continuing with respect to any First Priority Document, on the date on which such funds are requested to be released pursuant to such

Proceeds Release Request, the Collateral Trustee shall release to Satmex funds from the First Priority Collateral Trustee Segregated Sub-Account in accordance with such Proceeds Release Request. To effect such release, the Collateral Trustee shall liquidate such investments of such funds in the First Priority Collateral Trustee Segregated Sub-Account as shall be specified in such Proceeds Release Request.

4.2 Control of Collateral Account. All right, title and interest in and to the Collateral Account shall vest in the Collateral Trustee on behalf of the Secured Parties, and funds on deposit in the Collateral Account shall constitute part of the Trust Estate. The Collateral Account shall be subject to the sole and exclusive dominion and control of the Collateral Trustee.

4.3 Investment of Funds Deposited in Collateral Account. (a) The Collateral Trustee shall invest and reinvest moneys on deposit in the Collateral Account at any time in Cash Equivalents as directed in writing by Satmex so long as no Enforcement Period is in effect. All such investments of funds in the Collateral Account, including any Sub-Account, the interest and income received thereon and the net proceeds realized on the sale or redemption thereof shall be held in the Collateral Account or such Sub-Account as part of the Trust Estate.

(b) The Collateral Trustee shall have no obligation to invest or reinvest the amounts deposited in the Collateral Account if deposited with the Collateral Trustee after 11:00 a.m., New York time, on such day of deposit other than specified in clause (c) below. 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 Account, as outlined in subsection (a) above, shall be credited to the Collateral Account. Satmex shall be liable for any loss incurred on funds invested in any Cash Equivalents directed by it. The Collateral Trustee shall not be liable for any loss incurred on any funds invested or reinvested in Cash Equivalents pursuant to the provisions of this Section. In no event shall the Collateral Trustee be liable for the selection of investments or for losses incurred as a result of the liquidation of any investment prior to its stated maturity or for the failure of any appropriate Person to provide timely written investment direction. Any interest or other income received on such investment and reinvestment of amounts in the Collateral Account shall become part of the Collateral Account and any losses incurred on such investment and reinvestment of the amounts in the Collateral Account shall be debited against the amounts in the Collateral 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.

(c) Each party hereto agrees that the Collateral Account constitutes a “securities account” within the meaning of Section 8-501(a) of the UCC and in such capacity the Collateral Trustee shall be acting as a “securities intermediary” within the meaning of Section 8-102(a)(14) of the UCC and that, regardless of any provision in any other agreement,

for purposes of the UCC, the State of New York shall be deemed to be the “securities intermediary’s jurisdiction” under Section 8-110(e) of the UCC. Each item of property (whether investment property, financial asset, security, instrument or cash) credited to the Collateral Account shall be treated as a “financial asset” within the meaning of Section 8-102(a)(9) of the UCC.

(d) The financial assets credited to, and other items deposited to, the Collateral Account will not be subject to deduction, set-off, banker’s lien, or any other in favor of any Person other than as created pursuant to this Collateral Trust Agreement.

4.4 Application of Moneys. The Collateral Trustee shall have the right (pursuant to subsection 6.7 hereof) at any time to apply moneys held by it in the Collateral Account to the payment of due and unpaid Collateral Trustee Fees. All remaining moneys held by the Collateral Trustee in the Collateral Account or received by the Collateral Trustee while an Enforcement Period is in effect shall, to the extent available for distribution (it being understood that the Collateral Trustee may liquidate investments prior to maturity to make a distribution pursuant to this subsection 4.4), be distributed by the Collateral Trustee on each Distribution Date as follows:

First: to the Collateral Trustee, an amount equal to any unpaid Collateral Trustee Fees, and then to any Secured Party which has theretofore advanced or paid any Collateral Trustee Fees constituting administrative expenses allowable under 11 U.S.C. § 503(b), an amount equal to the amount thereof so advanced or paid by such Secured Party and for which such Secured Party has not been reimbursed prior to such Distribution Date;

Second: to any Secured Party which has theretofore advanced or paid any Collateral Trustee Fees other than such administrative expenses and has provided written notice of such advance or payment to the Collateral Trustee, an amount equal to the amount thereof so advanced or paid by such Secured Party and for which such Secured Party has not been reimbursed prior to such Distribution Date;

Third: to the Indenture Trustee, for redistribution or application in accordance with the terms of the First Priority Indenture, an amount equal to all sums which constitute First Priority Obligations then held by the Secured Parties, including without limitation the unpaid principal or face amount of, and unpaid interest on and other charges, if any, in respect of, the First Priority Obligations then outstanding whether or not due and payable and the costs and expenses of the Secured Parties and their respective representatives which are due and payable under the relevant First Priority Documents and which constitute First Priority Documents as of such Distribution Date; and

Fourth: after indefeasible payment in full of all First Priority Obligations, any surplus then remaining shall be paid to Satmex or its successors or to whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct.

4.6 [Intentionally Deleted]

4.7 Collateral Trustee’s Calculations. In making the determinations and allocations required by subsection 4.4, the Collateral Trustee may, unless a Responsible Collateral Trustee Officer has actual knowledge to the contrary, conclusively rely upon a certificate executed and supplied by the Indenture Trustee as to the amounts payable with respect to First Priority Obligations, all in accordance with subsection 8.2(b), and the Collateral Trustee shall have no liability to any of the Secured Parties for actions taken in reliance on such information; provided, however, that if the Indenture Trustee receives on any Distribution Date an amount pursuant to subsection 4.4 in excess of the amount to which it was entitled to receive on such Distribution Date pursuant to such subsection 4.4 as a result of any such certificate overstating the amount of the First Priority Obligations the Indenture Trustee shall pay such excess to the Collateral Trustee for application in accordance with subsection 4.4 as soon as practicable after the existence of such overstatement shall have been determined. All distributions made by the Collateral Trustee pursuant to subsection 4.4 shall be (subject to any decree of any court of competent jurisdiction and to the proviso in the preceding sentence) final, and the Collateral Trustee shall have no duty to inquire as to the application by any First Priority Holder or the Indenture Trustee of any amounts distributed to them. By accepting the benefits of this Trust Agreement, the First Priority Security Documents and the First Priority Guarantees, each Secured Party and the Indenture Trustee agrees to act in accordance with this Trust Agreement and not take any action inconsistent herewith.

4.8 Loral Usufructo.

(a) Each of the Collateral Trustee and the Indenture Trustee, each for themselves and on behalf of the First Priority Holders, hereby acknowledges that (i) consistent with Mexican law, the Loral Usufructo shall constitute an in rem property right whereby the Grant Holders are entitled to the quiet use and enjoyment of the Loral Transponders for (x) the life of Satmex 6 as to the Loral Transponders on Satmex 6 and (y) the life of Satmex 5 as to the Loral Transponders on Satmex 5; and (ii) as a consequence of the Loral Usufructo and consistent with Mexican law, the Loral Transponders cannot, under any circumstances, including, without limitation, in an insolvency, bankruptcy or similar proceeding under Mexican or U.S. law, be modified, diminished, sold, transferred, pledged or otherwise disposed of free and clear of the usufructo embodied in the ▇▇▇▇▇ ▇▇▇▇▇ and any purchaser or transferee thereof takes subject to the Loral Usufructo; provided, however, that the Grant Holders may, in their sole discretion, determine to accept the Loral Transponder Sale Proceeds in exchange for the termination and extinguishment of the Loral Usufructo as provided in Section 4.9 below.

existence of the Loral Usufructo and that the liens granted by Satmex to the First Priority Holders in the First Priority Collateral to secure the First Priority Obligations are subject to the Loral Usufructo. Each of the Collateral Trustee and the Indenture Trustee, each for themselves and on behalf of each of the First Priority Holders, shall not, and hereby waive any right to, foreclose the Loral Usufructo in the Loral Transponders.

(e) In any proceeding outside Mexico with respect to (x) the subject matter of section 5A(a)(iv) of the Restructuring Agreement, (y) the Loral Usufructo or the ▇▇▇▇▇ ▇▇▇▇▇ or (z) Satmex 5 or Satmex 6 as it relates to the rights of the Grant Holders in the Loral Transponders, each of the Collateral Trustee and the Indenture Trustee, each for themselves and on behalf of the First Priority Holders, irrevocably agree that ▇▇▇▇ ▇. ▇▇▇▇▇▇▇ or such other designee selected by the Grant Holders (the “Designee”), which Designee shall be reasonably acceptable to Satmex and the Collateral Trustee for the First Priority Holders and the collateral trustee for the Second Priority Holders, shall be the sole expert on Mexican law (specifically including Article 980) and agree that ▇▇. ▇▇▇▇▇▇▇ or such Designee will be the only witness (expert or otherwise) that may submit evidence including, without limitation, any expert report, testimony or opinion, for all purposes in interpreting, enforcing or otherwise explaining the Mexican Federal Civil Code, including Article 980 thereof, with respect to the Loral Usufructo and the ▇▇▇▇▇ ▇▇▇▇▇ or the parties’ rights in respect thereof (and each party shall waive any right to call any other witness in respect of these matters).

(f) Each of the Collateral Trustee and the Indenture Trustee, each for themselves and on behalf of the First Priority Holders, are and shall be estopped from arguing or taking any position that the Loral Usufructo embodied in the ▇▇▇▇▇ ▇▇▇▇▇ is other than as expressly described herein or therein.

(h) Neither the Loral Usufructo nor the ▇▇▇▇▇ ▇▇▇▇▇ shall affect the exercise of rights and remedies of any of the First Priority Holders, and, except in the event the Grant Holders shall elect to terminate the Loral Usufructo as provided in Section 4.9 below, the Loral Usufructo shall survive any exercise of such rights and remedies.

In no event shall Satmex 5 or Satmex 6, as applicable, be moved to the New Orbital Slot prior to the expiration of such ninety (90) day period.

8.6 Moneys to be Held in Trust. All cash, moneys, and proceeds of First Priority Collateral received by the Collateral Trustee under or pursuant to any provision of this Trust Agreement, any First Priority Guarantee or any First Priority Document (except Collateral Trustee Fees) shall be held in trust for the purposes set forth herein and in the other First Priority Documents.

8.7 Resignation and Removal of the Collateral Trustee.

the approval of such successor Collateral Trustee evidenced by one or more instruments signed by the Indenture Trustee, on behalf of the Requisite First Priority Holders, or the Requisite First Priority Holders. If no successor Collateral Trustee shall be appointed and shall have accepted such appointment within 90 days after the Collateral Trustee gives the aforesaid notice of resignation, the Collateral Trustee or any Secured Party, may apply to any court of competent jurisdiction to appoint a successor Collateral Trustee to act until such time, if any, as a successor Collateral Trustee shall have been appointed as provided in this subsection. Any successor so appointed by such court shall immediately and without further act be superseded by any successor Collateral Trustee appointed as provided in this subsection.

(b) The Requisite First Priority Holders may, at any time, remove the Collateral Trustee and appoint a successor Collateral Trustee, such removal to be effective upon the acceptance of such appointment by the successor.

(c) If at any time the Collateral Trustee shall resign or be removed or otherwise become incapable of acting, or if at any time a vacancy shall occur in the office of the Collateral Trustee for any other cause, a successor Collateral Trustee may be appointed by the Requisite First Priority Holders. In such event, the powers, duties, authority and title of the predecessor Collateral Trustee shall be terminated and cancelled without procuring the resignation of such predecessor and without any other formality (except as may be required by applicable law) than appointment and designation of a successor in writing duly acknowledged and delivered to the predecessor and Satmex. Such appointment and designation shall be full evidence of the right and authority to make the same and of all the facts therein recited, and this Trust Agreement, the First Priority Guarantees and the First Priority Security Documents shall vest in such successor, without any further act, deed or conveyance, all the estates, properties, rights, powers, trusts, duties, authority and title of its predecessor (subject to the lien of such predecessor pursuant to subsection 6.7); but such predecessor shall, nevertheless, on the written request of the Requisite First Priority Holders or the successor, execute and deliver an instrument transferring to such successor all the estates, properties, rights, powers, trusts, duties, authority and title of such predecessor hereunder and under the First Priority Security Documents and shall deliver all First Priority Collateral held by it or his agents to such successor (subject to the lien of such predecessor pursuant to subsection 6.7). Should any deed, conveyance or other instrument in writing from Satmex or any First Priority Guarantor be required by any successor Collateral Trustee for more fully and certainly vesting in such successor the estates, properties, rights, powers, trusts, duties, authority and title vested or intended to be vested in the predecessor Collateral Trustee, any and all such deeds, conveyances and other instruments in writing shall, on request of such successor, be executed, acknowledged and delivered by Satmex or such First Priority Guarantor, as applicable. If Satmex or any First Priority Guarantor shall not have executed and delivered any such deed, conveyance or other instrument within ten (10) calendar days after it received a written request from the successor Collateral Trustee to do so, or if an Enforcement Period is in effect, the predecessor Collateral Trustee may execute the same on behalf of Satmex or such First Priority Guarantor, as applicable. Satmex and each First Priority Guarantor hereby appoint any predecessor Collateral Trustee as its agent and attorney to act for such purposes.

8.8 Status of Successor Collateral Trustee. Every successor Collateral Trustee appointed pursuant to subsection 8.7 shall be a bank or trust company in good standing and

having power to act as Collateral Trustee hereunder, incorporated under the laws of the United States of America or any State thereof or the District of Columbia and having its principal corporate trust office within the forty-eight (48) contiguous United States and shall also have capital, surplus and undivided profits of not less than $150,000,000, if there be such an institution with such capital, surplus and undivided profits willing, qualified and able to accept the trust hereunder upon reasonable or customary terms.

8.9 Merger of the Collateral Trustee. Any corporation into which the Collateral Trustee may be merged, or with which it may be consolidated, or any corporation resulting from any merger 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, shall be Collateral Trustee under this Trust Agreement, the First Priority Guarantees, and the First Priority Security Documents without the execution or filing of any paper or any further act on the part of the parties hereto.

8.10 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 First Priority 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 Secured Parties, or the Requisite First Priority Holders shall in writing so 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 First Priority Security 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 an Enforcement Period is in effect, Satmex, either to act as co-trustee or co-trustees or agent or bailee of all or any of the First Priority Collateral under this Trust Agreement or under any of the First Priority 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 First Priority Collateral. If Satmex shall not have joined in the execution of such instruments and agreements within 10 days after it receives a written request from the Collateral Trustee to do so, or if an Enforcement Period is in effect, 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 subsection 8.7, 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 First Priority Guarantee or First Priority 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;

(iii) no power given hereby or by the relevant First Priority Guarantee or First Priority 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 the Requisite First Priority Holders, 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 days after it receives a written request from the Collateral Trustee to do so, or if an Enforcement Event is in effect, the Collateral Trustee shall have the power to (and, at the direction of the Requisite First Priority Holders, 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.

8.11 Treatment of Payee or Indorsee by Collateral Trustee; Representatives of Secured Parties.

(a) The Collateral Trustee may treat the registered holder or, if none, the payee or indorsee of any promissory note or debenture evidencing a First Priority Obligation as the absolute owner thereof for all purposes and shall not be affected by any notice to the contrary, whether such promissory note or debenture shall be past due or not.

(b) Any Person which shall be designated as the duly authorized representative of one or more Secured Parties to act as such in connection with any matters pertaining to this Trust Agreement or the First Priority Collateral shall present to the Collateral Trustee such documents, including, without limitation, Opinions of Counsel, as the Collateral Trustee may reasonably require, to demonstrate to the Collateral Trustee the authority of such Person to act as the representative of such Secured Parties (it being understood that the authority of the Indenture Trustee shall be demonstrated by its inclusion as such in the lists from time to time delivered pursuant to subsection 6.2.)

(c) Whenever this Trust Agreement requires or permits any Secured Party or the Requisite First Priority Holders to sign any instrument, give any notice or take any action, the Requisite First Priority Holders, the Indenture Trustee, or the Indenture Trustee on behalf of such Secured Party or Requisite First Priority Holders may sign such instrument, give such notice or take such action with the same effect as if done directly by such Secured Party or Requisite First Priority Holders.

(d) Notwithstanding anything to the contrary in this Trust Agreement or any First Priority Document, any Person holding a beneficial interest in any First Priority Security as of a date shall qualify hereunder as a First Priority Holder of that First Priority Security, to the extent of its beneficial interest, as of that date, and shall have the benefits hereunder of a First Priority Holder of that First Priority Security, to the extent of its beneficial interest, as of that date, upon providing to the Collateral Trustee written documentation of its beneficial interest as of that date that is reasonably satisfactory to the Collateral Trustee. For the purposes of the foregoing sentence, documentation of a beneficial interest meeting the requirements of Section 7.9 of the First Priority Indenture will be reasonably satisfactory.

8.12 Notices to Collateral Trustee under First Priority Security Documents. In the event that the Collateral Trustee receives any notice from the grantor under any First Priority Security Document, the Collateral Trustee shall promptly transmit a copy thereof to Satmex, the Indenture Trustee and the Collateral Trustee. The Collateral Trustee shall take such action in respect of such notice which is permitted by this Trust Agreement as shall be directed by the Requisite First Priority Holders.
