requirements of the MBRA. The parties to this Agreement acknowledge that the
Concurso Plan will set forth the final framework for the Restructuring but not
implement the restructuring of the debt or equity of the Company, which will be
restructured on the Effective Date.

          (b) The Concurso Plan shall not be binding upon any Supporting FRN
Holder or Supporting Noteholder that is a party to both this Agreement and the
Concurso Plan if, prior to the Effective Date, the Conciliador delivers a notice
(pursuant to the procedures immediately below) to the Mexican Bankruptcy Court
stating that this Agreement has terminated pursuant to its terms as to such
Supporting FRN Holder or Supporting Noteholder (the "Conciliador Termination
Notice"). Upon the good faith termination of this Agreement pursuant to its
terms by any Supporting FRN Holder or Supporting Noteholder, such Supporting FRN
Holder or Supporting Noteholder may deliver a certificate to the Company, its
U.S. counsel and the Conciliador stating that this Agreement has terminated
pursuant to its terms with respect to such Supporting FRN Holder or Supporting
Noteholder. Upon receipt of such certificate, the Company shall have, for
purposes of preventing delivery of the Conciliador Termination Notice, three (3)
Business Days to challenge the validity of such termination. If the Company
challenges the validity of such termination, the Conciliador shall not be
obligated to deliver the Conciliador Termination Notice unless the Supporting
FRN Holder or Supporting Noteholder has obtained an order of a court of
competent jurisdiction confirming the termination, as duly evidenced to the
Conciliador by written notice delivered pursuant to section 16 hereof, which
notice shall be accompanied by a copy of such order and all appropriate legal
documentation, if any, required by such court order (such notice, the
"Confirmation of Termination"). The Conciliador shall deliver a Conciliador
Termination Notice as to the applicable Supporting FRN Holder or Supporting
Noteholder to the Mexican Bankruptcy Court promptly upon (a) expiration of the
three (3) Business Day objection period so long as the Conciliador did not
receive within such period written notice delivered pursuant to section 16
hereof evidencing that the Company objected within the objection period or (b)
receiving a Confirmation of Termination if the Company did object within the
objection period. The delivery of the Conciliador Termination Notice

                                     - 11 -



following the commencement of the Chapter 11 Case shall not affect the Chapter
11 Case in any manner.

          (c) With respect to the Chapter 11 Plan, the requisite acceptances
will be solicited after the Company commences the Chapter 11 Case and in
accordance with the Bankruptcy Code and other Applicable Law. The parties to
this Agreement acknowledge that this Agreement is not a "convenio particular"
under Article 154 of the MBRA and that this Agreement shall be void ab initio in
the event that a court of competent jurisdiction enters a final order holding
otherwise.

     Section 3. Company's Obligations to Support Restructuring.

     The Company agrees that:

          (a) It shall use commercially reasonable efforts to propose, execute,
and seek creditor, Mexican Bankruptcy Court, and all other necessary approvals
(including all necessary government approvals) of the Concurso Plan and shall
seek entry of the Concurso Plan Order as promptly as practicable and in no event
later than the Outside Date; provided, however, that the Company shall not be
required to execute the Concurso Plan until the Conciliador has received
counterpart signature pages of the Concurso Plan executed by the Required FRN
Holders and the Required Noteholders.

          (b) It shall move to dismiss the 304 Proceeding and commence the
Chapter 11 Case to effectuate and implement the Restructuring through the
Chapter 11 Plan within five (5) Business Days following the entry of the
Concurso Plan Order (the "Chapter 11 Filing Trigger").

          (c) It shall use commercially reasonable efforts to (i) obtain the
approval by the Bankruptcy Court of the Disclosure Statement with respect to the
Chapter 11 Plan within forty-five (45) days of filing of the Petition and (ii)
cause the Chapter 11 Plan Order to be entered within one hundred and twenty
(120) days of filing of the Petition.

          (d) Subject to the terms and conditions set forth in this Agreement,
it shall perform its obligations hereunder and under the Term Sheet.

          (e) Except as required by Applicable Law, it will not take any action
(including, without limitation, any filing, pleading or other action in
connection with the Concurso Proceeding or Servicios Proceeding) that is
inconsistent with the implementation and effectuation of the Restructuring, the
Servicios Restructuring, the Concurso Plan or the Chapter 11 Plan in accordance
with this Agreement, nor take any action that would unreasonably delay the
consummation of the Restructuring, the Servicios Restructuring, the Concurso
Plan or the Chapter 11 Plan.

          (f) In the event that (i) the Effective Date has not occurred, (ii)
the Concurso Proceeding remains open or is continued, reactivated, or reopened,
or otherwise is or becomes pending, or any other or new proceeding under the
MBRA or successor statute in which the Company is the debtor is or becomes open,
pending, or active (such continued, reactivated, reopened, open, pending, or
active Concurso Proceeding or proceeding being a "Subsequent Concurso
Proceeding"), and (iii) this Agreement has been terminated as to all parties
hereto

                                     - 12 -



(other than a termination of this Agreement pursuant to section 33 hereof), the
parties to this Agreement hereby, subject to Applicable Law, waive and agree to
terminate (and to take all necessary actions to terminate) the conciliation
phase (as defined in Title V of the MBRA) of the Subsequent Concurso Proceeding;
provided, however, that such waiver and termination shall not take effect, and
the conciliation phase of the Subsequent Concurso Proceeding shall not be waived
or terminated, until the later of (x) the date that this Agreement is terminated
as to all parties hereto in accordance with the terms hereof, and (y) July 27,
2006. Notwithstanding anything to the contrary in this Agreement, this paragraph
shall survive the termination of this Agreement.

          (g) It shall use its reasonable best efforts to cause the Conciliador
to file the Concurso Plan with the Mexican Bankruptcy Court as soon as both the
Required FRN Holders and the Required Noteholders accept and execute the
Concurso Plan.

     Section 4. Conduct of Business Pending Consummation of Chapter 11 Plan.

     From and after the date hereof until the earlier of the (i) termination of
this Agreement in accordance with the terms specified herein and (ii) Effective
Date, the Company agrees to comply with the following covenants, unless
compliance is waived by a majority of the Supporting FRN Holders and a majority
of the Supporting Noteholders; provided, however, that only a majority of the
Supporting FRN Holders is necessary to waive the requirements of section 4(d)
below:

          (a) The Company shall not directly or indirectly take any action to or
suffer or permit any Person to do any of the following: (i) except that the
Company may, solely to the extent required to effect the Restructuring,
including any transactions set forth in the Term Sheet, (A) issue, sell, pledge,
dispose of or encumber any additional shares of, or any options, warrants,
conversion privileges or rights of any kind to acquire any shares of, its
capital stock, (B) materially amend its by-laws (estatutos sociales), (C) split,
combine or reclassify any outstanding shares of its capital stock, or declare,
set aside or pay any dividend or other distribution payable in cash, stock,
property or otherwise with respect to any of its shares of capital stock, (D)
redeem, purchase or acquire or offer to acquire any of its shares of capital
stock, (E) acquire, transfer, or sell (by merger, exchange, consolidation,
acquisition of stock or assets or otherwise) any corporation, partnership, joint
venture or other business organization or division, material asset thereof or
interest therein, (F) incur any indebtedness for borrowed money outside the
ordinary course of business consistent with prior business practices or issue
any debt securities outside the ordinary course of business consistent with
prior business practices and consistent with the allowance originally provided
for in the indentures pursuant to which the FRNs and Senior Notes were issued,
(G) enter into any transaction with any affiliate of the Company or its
shareholders (including Loral, Principia and their respective affiliates) other
than pursuant to existing agreements, (H) redeem, purchase or acquire or offer
to acquire any of the FRNs or Senior Notes; provided, however, that,
notwithstanding the foregoing and subject to the approval of the Majority
Noteholders, the Company may at any time redeem the FRNs, (I) increase the
compensation payable or to become payable to, or grant any severance or
termination pay or stay bonus to, any executive officer or director of the
Company except as agreed in connection with the Restructuring, (J) cancel or
terminate any applicable material insurance policy naming the Company as a
beneficiary or the Company or the collateral trustee

                                     - 13 -



for the FRNs (the "FRN Collateral Trustee") as a loss payee, (K) take any action
to modify, amend or cancel, any concession or other license from the Mexican
Government or any landing right agreements or concessions with any other country
necessary for the continued operation of the Company's satellite communications
network in the same manner as the Company operates such network on the date
hereof, or (L) transfer, sell, or otherwise dispose of any assets outside the
ordinary course of business consistent with prior practices; (ii) enter into any
material agreement or material arrangement, or materially modify any agreement
or arrangement, with any banker, advisors, consultants or attorney of the
Company in connection with any matter relating to the Restructuring or any
merger or acquisition of the Company or its assets; (iii) enter into any
agreement, arrangement or understanding to pay or provide to the holder of any
of the Company's Securities or any affiliate thereof, directly or indirectly,
any fee, expense or other payment or compensation, in connection with the
Restructuring or any part thereof; provided, however, that, upon notice to
counsel to the respective Committees, the Company shall be permitted to enter
into any such agreement, arrangement or understanding if such agreement,
arrangement or understanding is on equally or more favorable terms to the
Company than any agreement, arrangement or understanding to which the Company is
a party as of the date hereof; or (iv) enter into or propose to enter into, or
modify or propose to modify, any agreement, arrangement or understanding
inconsistent with the matters set forth in this section 4(a).

          (b) The Company shall not directly or indirectly engage in, agree to
or consummate any transaction outside the ordinary course of its business;
provided, however, that nothing herein shall limit the Company's ability to (i)
pay or otherwise satisfy all of the Recognized Claims (other than those related
to or connected with the FRNs and Senior Notes) immediately prior to the filing
of the Petition with the Bankruptcy Court or (ii) take such action as is
reasonably required to effect the Restructuring, including any transactions set
forth in this Agreement or the Term Sheet. For the avoidance of doubt, any
action taken by the Company consistent with industry practices to protect the
Satmex 6 Satellite during launch shall constitute activities conducted in the
ordinary course of business.

          (c) The Company shall (i) maintain its legal existence under the Laws
of Mexico and (ii) notify the Committees' respective counsel of any governmental
or third party complaints, investigations or hearings (or communications
indicating that the same may be contemplated or threatened) regarding the
Company, which could reasonably be anticipated to materially adversely affect
the business, property, or financial condition of the Company and its
subsidiaries considered as one enterprise.

          (d) The Company shall not launch the Satmex 6 Satellite until the
Concurso Filing Trigger has occurred; provided, however, that the restriction
provided for in this section 4(d) shall not apply if the Concurso Filing Trigger
does not occur due to (x) a breach by any Supporting FRN Holder or Supporting
Noteholder, or (y) the failure of the Required FRN Holders to (A) sign this
Agreement or (B) otherwise become irrevocably bound to support the Restructuring
(including to vote to accept the Chapter 11 Plan).

          (e) The Company shall use commercially reasonable efforts to keep the
FRN Advisors and Senior Note Advisors informed of any material development
concerning its negotiations with the Mexican Government on the Restructuring or
any of the concessions granted to the Company by the Mexican Government or
landing rights with other countries

                                     - 14 -



reasonably necessary for the continued operation of the Company's satellite
communications network as operated on the date hereof.

          (f) The Company shall insure the Satmex 6 Satellite in accordance with
Annex E, which insurance shall name the FRN Collateral Trustee as loss payee
and, to the extent the insurers will permit, as an additional insured. The
Company shall use its reasonable best efforts to cause the insurers to name the
FRN Collateral Trustee as additional insured. Prior to the launch of the Satmex
6 Satellite, the Company shall provide counsel to the Ad Hoc FRN Committee and
counsel to the Ad Hoc Senior Note Committee with an insurance certificate
demonstrating the Company's compliance with the first sentence of this
paragraph.

     Section 5. Supporting Holders' Obligations to Support Restructuring,
Concurso Plan and Chapter 11 Plan.

     From and after the date hereof and until the earlier of the (i) termination
of this Agreement in accordance with the terms specified herein and (ii)
Effective Date:

          (a) Each Supporting FRN Holder and Supporting Noteholder agrees to (i)
execute or cause to be executed the Concurso Plan and deliver to the Concilador
counterpart signature pages of the Concurso Plan promptly, but (A) with respect
to the Supporting FRN Holders, no later than eight (8) Business Days after the
effective date of the Conciliador's Submission and (B) with respect to the
Supporting Noteholders, no later than ten (10) Business Days after the effective
date of the Conciliador's Submission (provided, however, that no Supporting
Noteholder shall be required to execute the Concurso Plan unless Required FRN
Holders (1) sign this Agreement or (2) otherwise become irrevocably bound to
support the Restructuring (including to vote to accept the Chapter 11 Plan)) and
(ii) vote (or, in the case of managed accounts, instruct the custodial agent to
vote) to accept the Chapter 11 Plan promptly upon receipt of the Solicitation
Materials (but in all events before any deadlines for submitting such votes),
and to vote or take any other action (or, in the case of managed accounts,
instruct the custodial agent to vote) to reject any other bankruptcy plan,
convenio concursal, restructuring, reorganization, liquidation or similar
arrangement (in whatever jurisdiction proposed) that does not contain the terms
of the Restructuring substantially as set forth in the Term Sheet.

          (b) Each Supporting FRN Holder and Supporting Noteholder agrees,
subject to the provisions of this section 5(b) and Annex F hereto, that it shall
not, directly or indirectly, use (other than solely in connection with the
evaluation of, negotiation of or voting with respect to the Restructuring) or
disclose to any Person any information relating to the transactions contemplated
hereby or any information included herein including, without limitation, the
existence of this Agreement or the Term Sheet or any of the transactions
contemplated therein (such information being referred to herein as "Confidential
Information"). Each Supporting FRN Holder that is a party to that certain
confidentiality agreement with the Company, dated January 30, 2006, and
Supporting Noteholder that is a party to that certain confidentiality agreement
with the Company, dated November 30, 2005 (whether expired pursuant to its terms
or not), agrees, pending termination of this Agreement (either in its entirety
or with respect to such individual holder), to keep in strict confidence all
information previously provided to it regarding the Company pursuant to the
terms of such confidentiality agreement, and agrees that

                                     - 15 -



the "Disclosure Date" under any such agreement shall be the date of termination
of this Agreement.

          (c) Each Supporting Holder (except in the case of the Loral Pledge or
any exercise of rights by the secured party or collateral trustee in connection
therewith) hereby agrees that it shall not Transfer any Securities.
Notwithstanding the foregoing, except for the period beginning five (5) days
prior to the Conciliador's Submission (such date to be set forth in a notice
from the Company to counsel for the Committees) and ending upon the expiration
of the five (5) Business Day period referred to under article 162 of the MBRA
(or, if such five (5) Business Day period does not commence within twenty (20)
Business Days following the Conciliador's Submission, then the end of such
twenty (20) Business Day period) (the "Transfer Restriction Period"), any
Supporting FRN Holder or Supporting Noteholder may Transfer any Securities so
long as (i) the transferee agrees in writing to be bound by all of the terms and
conditions of this Agreement by executing the Accession Agreement attached
hereto as Annex B and/or a counterpart signature page to this Agreement in
accordance with section 25 below and (ii) to the extent such transfer is made
prior to the commencement of the Transfer Restriction Period, the transferee
provides the Company with certifications of the record holders (e.g., DTC or
Euroclear) and, if applicable, the custodian and the transferee evidencing the
beneficial ownership of the FRNs or Senior Notes (as applicable) transferred
thereby as soon as practicable following the effectiveness of the Transfer, but
in no circumstances later than two (2) Business Days after the effectiveness of
such Transfer. The transferee Supporting FRN Holder or Supporting Noteholder
must provide a copy of such executed Accession Agreement and/or signature page
to this Agreement within three (3) Business Days after the effectiveness of any
Transfer to any transferee; provided, however, that, from the date of such
Transfer to the date such transferee executes and delivers the Accession
Agreement and/or signature page to this Agreement to the Company, the transferor
Supporting FRN Holder or Supporting Noteholder shall remain fully liable for any
and all obligations of such transferee under this Agreement (including without
limitation any failure to act or breach hereunder) (the "Transferor
Obligation"). Subject to compliance with this section 5(c), (i) nothing
contained in this Agreement shall affect or restrict the right of a Supporting
FRN Holder or Supporting Noteholder to Transfer its Securities and (ii) upon the
transfer by a Supporting FRN Holder or Supporting Noteholder of all of its
Securities in compliance with the terms of this Agreement, such Supporting FRN
Holder or Supporting Noteholder shall have no further obligation or liability
hereunder other than for any default by such Supporting FRN Holder or Supporting
Noteholder that occurred prior to the effectiveness of the Transfer or the
Transferor Obligation. Additionally, except for Supporting FRN Holders that are
not domiciled in the United States of America, each Supporting FRN Holder hereby
agrees that prior to delivery of its vote to accept the Chapter 11 Plan, it
shall not, without the prior written consent of the Company (not to be
unreasonably withheld), Transfer any Securities to a transferee unless the
transferee is (x) a Person domiciled in the United States of America or with a
place of business in the United States of America, (y) is a fund managed by a
person domiciled in the United States of America or with a place of business in
the United States of America or (z) a Supporting FRN Holder or another holder
that has become party to this Agreement by executing the Accession Agreement
attached hereto as Annex B and/or a counterpart signature page to this Agreement
in accordance with section 25 below. Notwithstanding the foregoing, following
the performance by the Supporting Equity Holders of all obligations to be
performed hereunder, the Supporting Equity Holders may seek to cause the
transfer of the shares of Firmamento and Servicios directly or indirectly held
by

                                     - 16 -



them as necessary for tax purposes, as provided under the Term Sheet. For the
avoidance of doubt, any Transfer of the Senior Notes or FRNs that does not
comply with this section 5(c) shall be deemed ineffective to transfer any right
to accept or reject the Concurso Plan and Chapter 11 Plan, which right shall
remain with and be exercised only by the purported transferor.

          (d) No Supporting Holder may revoke, withdraw or modify the execution
of the Concurso Plan or any ballot tendered in connection with a vote to accept
the Chapter 11 Plan; provided, however, that prior to the Effective Date, if any
term or condition of the Chapter 11 Plan or Concurso Plan is modified, amended,
or waived in any material respect, a Supporting Holder shall have the right to
revoke, withdraw, or modify its vote to the extent that such vote may be
revoked, withdrawn or modified under Applicable Law unless such modification,
amendment, or waiver has been approved pursuant to section 13 hereof.

          (e) Each Supporting Holder agrees that (i) it will not, directly or
indirectly, execute, vote (or, in the case of managed accounts, instruct the
custodial agent to vote) for, consent to, provide any support for, participate
in the formulation of, or solicit or encourage others to formulate any
bankruptcy plan, convenio concursal, restructuring, reorganization, liquidation
or similar arrangement (in whatever jurisdiction proposed) for the Company or of
any of its affiliates other than the Restructuring, the Concurso Plan, the
Chapter 11 Plan and the Servicios Restructuring, (ii) in the case of the
Supporting FRN Holders and the Supporting Noteholders, it will use its
commercially reasonable efforts to cause all of the members of the Ad Hoc FRN
Committee and/or the Ad Hoc Senior Note Committee (as applicable) to take all
actions necessary to effectuate the Restructuring and consummate the Concurso
Plan and the Chapter 11 Plan; provided, however, that nothing herein shall
require the Supporting FRN Holders or Supporting Noteholders to indemnify the
indenture trustee for the FRNs or Senior Notes or the FRN Collateral Trustee, as
applicable, (iii) in the case of the Supporting FRN Holders, it will use its
commercially reasonable efforts to cause all of the members of the Ad Hoc FRN
Committee to take all actions necessary to effectuate the Servicios
Restructuring and, except as otherwise required to effect the Servicios
Restructuring, each Supporting FRN Holder shall not, directly or indirectly
through the FRN Collateral Trustee, take or cause to be taken, by exercise of
rights under the stock trusts securing the guarantees of the FRNs, any
shareholder action of Servicios; provided, however, that nothing herein shall
require the Supporting FRN Holders to indemnify the FRN Collateral Trustee, (iv)
it will support the Restructuring and approval of the Concurso Plan and the
Chapter 11 Plan including without limitation, in the case of the Supporting
Equity Holders, to vote (or cause to be voted) their direct and indirect shares
of Existing Equity in support of the Restructuring and to approve the Concurso
Plan; provided, however, that the Supporting Equity Holders shall vote (or cause
to be voted by the exercise of rights under the stock trusts securing the
guarantees of the FRNs or the Menoscabo or otherwise) their indirect shares of
Existing Equity only if they have the right to vote such shares and only if the
voting of such shares is not reasonably likely to lead based on the advise of
counsel to the incurrence of any liability of the Supporting Equity Holders as a
result thereof and (v) subject to section 30 hereof, it will permit public
disclosure, in a mutually agreed upon press release of the contents of this
Agreement (including, but not limited to, the commitments given in this section
5 and the Term Sheet).

          (f) Each Supporting Holder further agrees that it will not object to,
or otherwise commence any proceeding to oppose, the Restructuring or the
Concurso Plan or

                                     - 17 -


Chapter 11 Plan or the Servicios Restructuring and shall not
take any action in opposition to, or that would unreasonably delay the
consummation of, the Restructuring or the Concurso Plan or Chapter 11 Plan or
the Servicios Restructuring.

          (g) Each Supporting Holder further agrees that any and all Securities
acquired by such Supporting Holder following the date of this Agreement shall be
subject to the terms and conditions of this Agreement and shall be subject to
the same treatment as the Securities held by such Supporting Holder as of the
date hereof. Notwithstanding anything contrary to the foregoing, each Supporting
Holder that acquires or disposes of any Securities after the date hereof shall
promptly send a written notice to the other parties hereto specifying the type,
amount and/or number (as applicable) of Securities acquired or disposed.

          (h) Each Supporting Holder further agrees that it will not request (or
support any other Supporting Holder or other party requesting) or otherwise file
any motion or commence any action or proceeding, seeking adequate protection.

          (i) Each Supporting Noteholder agrees that it will cause its appeal of
the Recognition Judgment to be withdrawn on or before the submission of the
Concurso Plan to the Mexican Bankruptcy Court by the Conciliador.

          (j) Except as otherwise required to effect the Restructuring, each
Supporting FRN Holder shall not, directly or indirectly through the FRN
Collateral Trustee, take or cause to be taken, by exercise of rights under the
stock trusts securing the guarantees of the FRNs, any shareholder action of the
Company including, among others, any of the actions mentioned in section 4.

          (k) For the avoidance of doubt, nothing in this Agreement shall, or
shall be construed to, impose any restriction or limitation on the ability of
any party to the Loral Settlement Agreements to enforce its rights or to
exercise its remedies in respect of the Loral Settlement Agreements and such
party shall incur no liability under this Agreement for the enforcement of its
rights or exercise of its remedies in respect of the Loral Settlement
Agreements.

          (l) The Supporting Holders hereby consent (to the extent such consent
is required) to (i) the representation of Servicios by Javier Quijano Baz and/or
Alfonso Martin Lopez Melih in the Servicios Proceeding and (ii) the appointment
of Thomas Stanley Heather Rodriguez as conciliador and/or sindico in the
Servicios Proceeding; provided, however, that such persons will not be
compensated for such services other than for all reasonable out-of-pocket
expenses incurred in connection with the Servicios Proceeding, which shall be
borne by the Company in accordance with section 8(k) hereof. Nothing in this
paragraph will affect payment of the Conciliador's fees, as provided under
section 8(o) hereof.

          (m) The Supporting Holders hereby consent to the payment by the
Company of success fees to the Company's advisors in accordance with the
retention agreements of such advisors as amended as of the date hereof, in each
case that have been provided to the FRN Advisors and Senior Note Advisors by the
Company.

                                     - 18 -


          (n) The Supporting FRN Holders and the Supporting Noteholders hereby
consent to the execution of the 304 Stipulation by the Company.

     Section 5A. Loral's Obligation to Support Restructuring, Concurso Plan and
Chapter 11 Plan.

          (a) Notwithstanding anything to the contrary set forth herein, this
Agreement may be terminated by Loral as to itself only, if any of the following
shall not have occurred or not have been complied with in all respects:

          (i) The 304 Stipulation shall become a final and non-appealable order
     by May 9, 2006 and time is of the essence with respect thereto.

          (ii) The provisions of the 304 Stipulation shall have been fully
     complied with.

          (iii) The Loral Documents and the Equity Documents shall be in form
     and substance reasonably satisfactory to counsel to Loral on or before the
     respective effective dates of such documents. Loral shall be provided with
     an initial draft of each of the Loral Documents and the Equity Documents
     (each, an "Initial Draft") at the same time such Initial Draft is provided
     to counsel for any of the Supporting Holders but in no event later than
     forty-five (45) days prior to the earlier of (I) the respective effective
     date of each Loral Document or Equity Document and (II) the Effective Date.
     Loral shall only be permitted to terminate this Agreement pursuant to this
     section 5A(a)(iii) if (x) Loral is not provided with an Initial Draft as
     specified in the immediately preceding sentence, (y) after provision of
     notice to the Company that an Initial Draft is not in form and/or substance
     reasonably satisfactory to Loral, Loral does not receive a successive draft
     (a "Successive Draft") of such Initial Draft within five (5) Business Days,
     or (z) if such Successive Draft is not in form and/or substance reasonably
     satisfactory to Loral, and Loral notifies the Company of such termination
     within ten (10) Business Days of receipt of such Successive Draft.

          (iv) On the Effective Date, the Company shall grant to certain
     affiliates of Loral as designated by Loral (the "Loral Entities") a
     usufructo under Articles 980 et seq. of Mexico's Federal Civil Code
     ("Article 980") (the "Loral Usufructo") with respect to the Loral
     Transponders (the "Loral Grant"), which Loral Grant shall conform to the
     requirements set forth herein and in the Term Sheet. Each of the parties to
     this Agreement agrees that (a) consistent with Mexican law, the Loral
     Usufructo shall constitute an in rem property right whereby the Loral
     Entities and their assignees (collectively, the "Grant Holders") are
     entitled to the quiet use and enjoyment of the Loral Transponders for (x)
     the life of the Satmex 6 Satellite as to the Loral Transponders on the
     Satmex 6 Satellite and (y) the life of the Satmex 5 Satellite as to the
     Loral Transponders on the Satmex 5 Satellite; (b) 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
     sold, transferred, pledged or otherwise disposed of free and clear of the
     usufructo embodied in the Loral Grant and any purchaser or transferee
     thereof takes subject to the Loral Usufructo; provided, however, that
     solely in the event the Grant Holders determine to accept the Sale Proceeds
     (as defined in the Term Sheet) in exchange for the termination and
     extinguishment

                                     - 19 -



     of the Loral Usufructo as provided herein and in the Term Sheet, the
     collateral trust agreements shall provide and the collateral trustee under

Company.

          (b) Each of the Supporting Holders acknowledges that all documents,

have been made available for inspection by it, its attorneys, financial advisors
and accountants, and that it understands that all such documents, books and
records will continue to be made available to it, its attorneys, financial
advisors and accountants for inspection upon reasonable notice, during

advisors has had a reasonable opportunity to ask questions of and receive
answers from the officers of the Company, or a Person or Persons acting on their
behalf, concerning the Company and the terms and conditions of the
Restructuring, the Concurso Plan and the Chapter 11 Plan, and to obtain
additional information, to the extent possessed or obtainable without
unreasonable effort or expense by the officers of the Company, necessary to
confirm the accuracy of the information provided by, or on behalf of, the
Company.

in financial and business matters as to enable it (i) to utilize the information
made available to it in connection with the Restructuring (including the Term
Sheet), (ii) to evaluate the merits and risks associated with the Restructuring

records, and shall cooperate in the examination thereof and furnish such
advisors with all reasonable information with respect to the business and
affairs of the Company and Enlaces as such advisors may reasonably request
during normal business hours, subject to existing confidentiality obligations
and to any applicable privileges. Nothing in this section 29(f) shall obligate
the Company to prepare any information not prepared in the ordinary course of
business. All information furnished to the FRN Advisors and the Senior Note
Advisors pursuant to this section 29(f) shall be subject to the provisions of

      Prior to the issuance of any public disclosures regarding the
Restructuring, the Company shall consult with the Committees' and Supporting
Equity Holders' respective counsel as to the form and substance of such public
disclosures materially related to this Agreement or any other transaction
contemplated hereby; provided, however, that nothing in this section 30 shall be
deemed to prohibit the Company from making any disclosure it deems necessary or
advisable in order to satisfy its respective disclosure obligations imposed by
Applicable Law or the rules of any stock exchange on which securities of the
Company are listed or quoted or to obtain any governmental approvals or filings
necessary to implement the Restructuring and consummate the Concurso Plan and
the Chapter 11 Plan. Notwithstanding the foregoing, the amount of Securities
held by a specific Supporting FRN Holder or Supporting Noteholder shall not be
publicly disclosed by the Company or any party hereto without the prior written
consent of such Supporting FRN Holder or Supporting Noteholder other than in
connection with the Chapter 11 Case and then only the identity of such
Supporting FRN Holder or Supporting Noteholder and the amount of Securities held
on an aggregate basis with all members of the applicable Committee; provided,
however, that, to the extent requested, the Company may disclose individual
Supporting FRN Holder and Supporting Noteholder information to a Governmental
Authority in order to obtain any governmental approvals or filings necessary to
implement the Restructuring and consummate the Concurso Plan and the Chapter 11
Plan.

      Section 31. Impact of Appointment to Creditors' Committee.

      Notwithstanding anything herein to the contrary, if any Supporting Holder
is appointed to and serves on any official committee of creditors or equity
holders in the Company's Chapter 11 Case, the terms of this Agreement shall not
be construed so as to limit such Supporting Holders' exercise (in its reasonable
judgment and discretion) of its fiduciary duties to any Person arising from its
service on such official committee, and any such exercise (in the reasonable
judgment and discretion of such Supporting Holder) of such fiduciary duties
shall not be deemed to constitute a breach of the terms of this Agreement.
Notwithstanding anything to the contrary herein, no Supporting Holder shall
request the appointment and/or creation of any trustee, examiner or committee
pursuant to the Bankruptcy Code or otherwise until such time as this Agreement
has been terminated pursuant to the terms specified herein.

      Section 32. Survival.

      The representations, warranties, covenants, obligations, rights and
remedies of the parties hereto under this Agreement shall be of no further force
and effect upon the termination of this Agreement pursuant to the terms
specified herein; provided, however, that the Company shall be liable pursuant
to section 8 of this Agreement for any reasonable fees and actual, documented
out-of-pocket expenses incurred from the date hereof until termination of this
Agreement.

      Section 33. Automatic Termination.

      This Agreement shall automatically terminate if on or before the earlier
of (i) the Concurso Filing Deadline and (ii) May 22, 2006 (the "Termination
Date"), Required FRN Holders have not (A) signed this Agreement or (B) otherwise
become irrevocably bound to

                                      - 41 -



support the Restructuring (including to vote to accept the Chapter 11 Plan);
provided, however, that the Termination Date may be extended, or this section 33
may be waived, by (x) the majority of the Supporting Noteholders and (y) the
Company, acting jointly. The Company shall promptly notify the respective
counsel to the Committees in the event the Required FRN Holders have (A) signed
this Agreement or (B) otherwise become irrevocably bound to support the
Restructuring (including to vote to accept the Chapter 11 Plan) and, in the case
of (B), shall provide such counsel with the relevant documentation thereof or
other evidence reasonably acceptable to counsel to the Committees. The parties
acknowledge that the Company will be relying upon information provided to it
from the security holders.

Treatment of Enlaces:           As of December 31, 2005, Loral and Principia
                                contributed U.S. $2.3 million in equity to and
                                there were loans totaling U.S. $7.6 million from
                                SATMEX on the books of Enlaces Integra, S.A. de
                                C.V. ("ENLACES"). On or before the Effective
                                Date, or as soon thereafter as all required
                                regulatory approvals are obtained, SATMEX will
                                capitalize the entire U.S. $7.6 million of such
                                loans in return for seventy-five percent (75%)
                                of the fully diluted equity of Enlaces.

                                Any new equity infusions with respect to Enlaces
                                will be subject to a rights offering. The
                                Enlaces board of directors will be comprised of
                                three members, two of which will be designated
                                by SATMEX and one of which will be designated
                                jointly by Loral and Principia. SATMEX, Loral
                                and Principia will agree on a list of Enlaces
                                extraordinary actions that will be subject to
                                the prior approval of the Loral/Principia
                                director.

                                On or before the Effective Date, Enlaces will
                                enter into a contract with Globalstar de Mexico
                                S. de R.L. de C.V. ("GLOBALSTAR DE MEXICO"), a
                                company owned jointly by an affiliate of Loral
                                and Principia, or its designee, to provide
                                services at Enlaces' current market rates to
                                support Globalstar de Mexico's Enciclomedia
                                business. Satmex will continue to support
                                Enlaces with the transponder capacity necessary
                                to meet its obligations under the
                                above-referenced contract, on commercially
                                reasonable terms negotiated on an arms-length
                                basis. For the avoidance of doubt, all contracts
                                between Enlaces and Globalstar de Mexico or
                                between SATMEX and Globalstar de Mexico shall be
                                on an arms-length basis and subject to approval
                                by the Bondholders.

                                SATMEX will endeavor to obtain all required
                                regulatory approvals prior to the Effective
                                Date, or as soon thereafter as is practicable.
                                Except for the capitalization of the U.S. $7.6
                                million in loans described above, nothing herein
                                shall affect any right or remedy of Satmex or
                                Enlaces under any existing agreement, contract,
                                Applicable Law or other course of business
                                between Satmex and Enlaces.

Loral Transponders:             On the Effective Date, SATMEX shall grant to
                                certain affiliates of Loral as designated by

                                SATMEX 5 satellite ("SATMEX 5") as to the Loral
                                Transponders on SATMEX 5; (b) as a consequence
                                of the Loral Usufructo and consistent with

                                of free and clear of the usufructo embodied in
                                the Loral Grant and any purchaser or transferee
                                thereof takes subject to the Loral Usufructo;
                                provided, however, that solely in the event the

                                as it relates to the rights of the Grant Holders
                                in the Loral Transponders, the parties to the
                                Agreement hereby irrevocably agree that Luis A.
                                Nicolau or such other designee selected by the
                                Grant Holders (the "DESIGNEE"), which Designee
                                shall be reasonably acceptable to Satmex and the

                                Senior Secured Notes and Second Priority Senior
                                Secured Notes, shall be the sole expert on
                                Mexican law (specifically including Article 980)
                                and agree that Mr. Nicolau or such other
                                Designee will be the only witness (expert or
                                otherwise) that may submit evidence including,
                                without limitation, any expert report, testimony

                                      A-3


                                Loral Usufructo and the Loral Grant 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 parties to the Agreement is and shall be
                                estopped from arguing or taking any position
                                that the Loral Usufructo embodied in the Loral
                                Grant is other than as expressly described
                                herein; and (g) in any dispute (in any court or
                                other proceeding whether in Mexico, the United
                                States or otherwise) with respect to the Loral
                                Usufructo embodied in the Loral Grant, the laws
                                of Mexico shall apply in connection with the
                                interpretation, enforceability and application
                                of the Loral Usufructo, and such application of
                                Mexican law is to be considered to the fullest
                                extent under Rule 44.1 of the Federal Rules of
                                Civil Procedure and Rule 9017 of the Federal
                                Rules of Bankruptcy Procedure, as may be
                                applicable. Further, the Loral Grant shall (a)
                                be subject to the provisions of this Section,
                                (b) be on the same business terms as the Lease

                                solely to the extent necessary, to reflect the
                                change from a lease to a usufructo structure, it
                                being expressly understood that the parties
                                hereto are agreeing to a usufructo and not a
                                lease in respect of the Loral Transponders and
                                (c) expressly set forth that (i) SATMEX shall,
                                to the extent reasonably necessary, assist the
                                Grant Holders in describing to their customers
                                the extent of the Grant Holders' rights, (ii)
                                the Grant Holders shall not be obligated to
                                maintain the Loral Transponders, except to the
                                extent, if any, expressly provided in the Lease
                                Agreements, (iii) the Loral Grant shall
                                terminate only in the circumstance described in
                                the following paragraph, (iv) except as provided
                                in the following paragraph, the Loral Grant
                                shall survive any sale or foreclosure of the
                                record title of the Loral Transponders or the
                                satellite in which the Loral Transponders are
                                located (v) the Grant Holders shall not be
                                obligated to provide any guarantee (fianza) in
                                respect of the Loral Grant and (vi) the Grant
                                Holders shall be entitled to indemnification
                                from SATMEX as provided in the Lease Agreements.
                                The liens on substantially all of SATMEX's
                                assets securing the First Priority Senior
                                Secured Notes and the Second Priority Senior
                                Secured Notes shall, with respect to the Loral
                                Transponders, be subject to, and acknowledge the
                                existence of, the Loral Grant as described
                                herein. The Loral Grant shall provide the Grant
                                Holders with the right to make one or more
                                protective UCC filings with regard to the Loral
                                Grant. SATMEX shall cooperate with the Grant
                                Holders and execute such documents as may be
                                necessary or appropriate to effect such filings.

                                The Loral Grant will not affect the exercise of
                                rights and remedies of the First Priority Senior
                                Secured Notes and the Second Priority Senior
                                Secured Notes. The Loral Grant shall survive any
                                exercise of such rights and remedies; provided,
                                however, that, if as a result of any such
                                exercise, SATMEX 5 or 6 is sold and moved from
                                the orbital slot for which it was designed, the
                                applicable Grant Holder shall be entitled to
                                receive, but only if the applicable Grant Holder
                                shall, in its sole discretion, elect not to
                                continue the Loral Grant at the new orbital
                                location from the net proceeds from the sale of
                                the respective satellite, the following (the
                                "SALE PROCEEDS"): the greater of (A) (i) in the
                                case of SATMEX 5, an amount equal to 6.25% of
                                such net sale proceeds and (ii) in the case of
                                SATMEX 6, an amount equal to 6.7% of such net
                                sale proceeds and (B) an amount equal to the
                                fair market value of the Loral Transponders as
                                determined by a panel of three satellite
                                industry experts on satellite valuation, with
                                such

                                      A-4


                                experts to be selected in the following manner:
                                each of (x) the Grant Holders and (y) the
                                applicable collateral trustee shall appoint one
                                of the experts and the experts so appointed by
                                the Grant Holders and the applicable collateral
                                trustee shall mutually agree on the third
                                expert. It is agreed that for the purposes of
                                such valuation, the experts shall assume that
                                the satellite has not been and will not be moved
                                from the orbital location for which it was
                                designed and, further, that the experts shall
                                take into account, among other things, the
                                customer base on the Loral Transponders existing
                                at the time of the valuation. The applicable
                                collateral trustee shall afford the Grant
                                Holders the same opportunity as any other
                                third-party bidder to bid on and purchase the
                                applicable satellite in any foreclosure, but
                                nothing in this sentence shall give the Grant
                                Holders any rights greater than any other
                                third-party bidder. The applicable Grant Holder
                                shall release the Loral Grant with respect to
                                the satellite in question (and shall be
                                obligated only to return the Loral Transponders
                                in their "as is" condition) upon receipt of the
                                Sale Proceeds. In addition, whether or not the
                                applicable Grant Holder elects to continue the
                                Loral Grant at the new orbital location pursuant
                                to any such exercise of rights and remedies that
                                result in the move of the satellite from its
                                orbital slot, the applicable Grant Holder shall
                                be entitled to an unsecured claim against SATMEX
                                in an amount equal to the direct damages that
                                will be incurred by the applicable Grant Holder
                                under customer contracts utilizing capacity on
                                the Loral Transponders that arise from or relate
                                to the move of the satellite from its orbital
                                slot. Receipt of the Sale Proceeds shall be in
                                full satisfaction of any and all claims that the
                                applicable Grant Holder may have against the
                                applicable satellite or any subsequent owner
                                thereof.

                                The Loral Grant shall become effective upon
                                filing for registration in the Public Registry
                                of Commerce, at which time the Lease Agreements
                                shall be terminated and the Grant Holders shall
                                have no further right to a lien on, or title to,
                                the Loral Transponders, except as provided in
                                the Loral Grant.

                                For purposes hereof, "LEASE AGREEMENTS" means,
                                collectively, (i) that certain Agreement
                                Concerning the Lease of Transponders dated June
                                14, 2005 between SATMEX and Loral Skynet, a
                                division of Loral SpaceCom Corporation, as
                                amended and (ii) that certain Agreement
                                Concerning the Lease of Transponders dated June
                                14, 2005 between SATMEX and SS/L (as assignee of
                                Loral Space & Communications Corporation), as
                                amended; and "LORAL TRANSPONDERS" means those
                                transponders that are the subject of the Lease
                                Agreements.

                                Upon the Effective Date, irrespective of whether
                                Loral has breached or terminated the Agreement
                                (as may be amended in accordance therewith), the
                                Loral Entities shall receive the Loral
                                Usufructo. With respect to SATMEX, the
                                obligation to provide the Loral Usufructo to the
                                Loral

                                      A-5


                                Entities shall survive termination of the
                                Agreement.

SS/L Right of First Offer:      Space Systems/Loral, Inc. ("SS/L") shall have a
                                right of first offer ("ROFO") from SATMEX with
                                respect to the construction of SATMEX's next
                                satellite to be placed into one of SATMEX's
                                existing orbital locations or any orbital
                                location obtained in exchange for any of
                                SATMEX's existing orbital locations (the "NEXT
                                SATELLITE"). Pursuant to this ROFO, SATMEX
                                shall, in the event it determines to procure the
                                Next Satellite, provide to SS/L a request for
                                proposal (an "RFP") outlining the specifications
                                for the Next Satellite.

                                SS/L shall have a period of forty-five (45) days
                                from receipt of the RFP to respond with a
                                written proposal. After receipt of SS/L's
                                proposal, SATMEX shall for a period not to
                                exceed forty-five (45) days thereafter negotiate
                                in good faith with SS/L regarding the proposal
                                and shall elect (the "ELECTION") either to enter
                                into a contract with SS/L based on the terms
                                proposed and negotiated or to reject SS/L's
                                proposal. If SATMEX elects to reject SS/L's
                                proposal, SATMEX may then solicit proposals
                                (based on the same RFP submitted to SS/L) from
                                other satellite manufacturers that could lead to
                                a Superior Proposal, and during the one hundred
                                twenty (120) day period after the Election,
                                enter into a contract for the construction of
                                the Next Satellite with a party other than SS/L
                                if SATMEX receives a Superior Proposal from such
                                party. A "SUPERIOR PROPOSAL" shall mean a
                                proposal that provides superior value to SATMEX,
                                as reasonably determined by SATMEX, taking into
                                account technical capabilities, schedule,
                                reliability, price and terms and conditions. If
                                (i) after the expiration of such 120-day period,
                                SATMEX has not entered into a satellite contract
                                with another manufacturer for the Next
                                Satellite, or (ii) at any time, SATMEX makes any
                                material changes or modifications to the
                                original or any subsequently modified RFP
                                submitted to SS/L, then SATMEX shall again
                                extend the ROFO to SS/L (a "SUBSEQUENT ROFO") in
                                accordance with the above terms; provided,
                                however, that in the event of a Subsequent ROFO
                                pursuant to clause (i), each 45-day period and
                                the 120-day period set forth above shall be
                                reduced to thirty (30) and sixty (60) days,
                                respectively. Notwithstanding the foregoing,
                                SATMEX may elect to accept a proposal from
                                another manufacturer that is not fully compliant
                                with the RFP, and such acceptance shall not be
                                construed as a material change or modification
                                to the original or any subsequently modified RFP
                                requiring the Subsequent ROFO, so long as such
                                variance from the RFP was not made at SATMEX's
                                request or with SATMEX's prior consent and such
                                proposal, after taking into account this
                                variance, nevertheless constitutes a Superior
                                Proposal. For the avoidance of doubt, the
                                acceptance by SATMEX of a non-compliant bid from
                                another manufacturer shall not constitute
                                consent for the purpose of the preceding
                                sentence.

                                Provided SATMEX shall comply with this ROFO,
                                SATMEX shall have

                                      A-6


                                no other or further obligation to SS/L with
                                respect to SATMEX's Next Satellite. Any dispute
                                between the parties concerning this ROFO shall
                                be governed by New York law, and the courts of
                                New York shall have exclusive jurisdiction to
                                determine such dispute.

                                If SATMEX purchases an existing satellite to be
                                located in one of SATMEX's orbital slots, then
                                the Next Satellite shall be the next satellite
                                to be constructed and placed in a SATMEX orbital
                                slot. The ROFO described in this section shall
                                apply to any successor-in-interest to or buyer
                                of SATMEX, but only with respect to the Next
                                Satellite.

                                The ROFO provided for herein shall expire ten
                                (10) years from the Effective Date.

Releases:                       On the Effective Date, appropriate discharges
                                and releases reasonably acceptable to the
                                Conciliador shall be provided by SATMEX to its
                                current officers and directors, to the extent
                                permitted by law. The Conciliador shall use
                                reasonable efforts to obtain similar discharges
                                and releases of SATMEX's current officers and
                                directors from the Mexican Government.

II. TREATMENT OF EXISTING SENIOR SECURED FLOATING RATE NOTES DUE 2004: FIRST
PRIORITY SENIOR SECURED NOTES

Issuer:                         SATMEX.

Targeted Securities:            For all outstanding principal amount of the FRNs
                                and all past due and unpaid interest on the
                                FRNs, the holders thereof will receive First
                                Priority Senior Secured Notes due 2011 (the
                                "FIRST PRIORITY SENIOR SECURED NOTES").

Principal Amount:               Approximately U.S. $203,400,000 plus unpaid
                                accrued interest through the Effective Date with
                                such interest calculated such that, assuming an
                                Effective Date of September 30, 2006, the
                                principal amount of the First Priority Senior
                                Secured Notes will be U.S. $234,400,000. In the
                                event the Effective Date is other than September
                                30, 2006, the principal amount shall be adjusted
                                upward for each day after September 30, 2006, or
                                downward for each day before September 30, 2006,
                                as applicable, that the Effective Date occurs,
                                by the following amount: U.S. $234,400,000
                                multiplied by the per Diem Rate multiplied by
                                the number of days before or after September 30,
                                2006, that the Effective Date occurs. The "PER
                                DIEM RATE" shall mean a percentage equal to the
                                one-month LIBOR rate as of the date that is
                                three (3) business days prior to the Effective
                                Date

                                      A-7


                                plus four hundred and fifty basis points
                                (LIBOR+4.5%) divided by three hundred sixty
                                (360). For the avoidance of doubt, nothing
                                herein shall create an obligation by SATMEX for
                                its internal accounting purposes to treat
                                amounts paid above the principal amount of the
                                FRNs in a manner inconsistent with its current
                                tax and accounting practices.

Ranking and Security:           The First Priority Senior Secured Notes will
                                continue to be secured by a first priority lien
                                on all present and after acquired assets of
                                SATMEX on substantially the same terms provided
                                for under the existing security documents for
                                the holders of the FRNs (junior only to
                                priorities recognized by statute in Mexico)
                                except (i) as provided for in Section I above
                                under the caption "LORAL TRANSPONDERS", and (ii)
                                as provided for immediately below under the
                                caption "GUARANTEES".

Guarantees:                     The First Priority Senior Secured Notes will not
                                be guaranteed in any manner by Servicios or by
                                Firmamento; consequently, liens on the shares of
                                SATMEX owned by Servicios and those of Servicios
                                owned by Firmamento will be discontinued as of
                                the Effective Date. The First Priority Senior
                                Secured Notes will be guaranteed by Restricted
                                Subsidiaries, following the concept in the
                                existing Senior Notes indenture. Restricted
                                Subsidiary guarantors will grant a lien on all
                                of their respective assets to secure the
                                guarantees, which liens will be senior in
                                priority, operation, and effect to the security
                                interests of the Second Priority Senior Secured
                                Notes in accordance with Exhibit A.

Interest Payments:              1 (one) or 3 (three) month LIBOR plus eight
                                hundred seventy five basis points per annum
                                (LIBOR+8.75%), payable in arrears in cash on the
                                last day of the applicable one or three month
                                period.

Final Maturity:                 Five years from the Effective Date.

                                of such Second Priority Senior Secured Notes
                                then outstanding plus accrued and unpaid
                                interest thereon.

Guarantors:                     Restricted Subsidiaries, as defined in and
                                required by the existing Senior Notes indenture,
                                which guarantees will rank pari passu in right
                                of payment to all existing and future senior
                                indebtedness of such Guarantors and will rank
                                senior to all existing and future subordinated
                                indebtedness of such Guarantors, subject to any
                                priorities recognized by statute, such as tax
                                and labor obligations. Restricted Subsidiary

                                respective assets to secure the guarantees,
                                which liens will be junior in priority,
                                operation, and effect to the security interests
                                of the First Priority Senior Secured Notes in
                                accordance with Exhibit A.

                                the existing Senior Notes indenture and
                                otherwise as is typical for similar
                                restructuring transactions, plus covenants
                                against (a) the incurrence of any new

                                      A-12


                                indebtedness (other than unsecured and
                                subordinated indebtedness for replacement
                                satellites and other agreed upon exceptions) and
                                (b) the making of any capital expenditures (with
                                details and permitted exceptions to be
                                determined). Mandatory periodic reporting
                                requirements in compliance with U.S. GAAP;
                                SATMEX will be subject to periodic reporting

                                companies under the Securities Exchange Act. In
                                any event, covenants shall not be more
                                restrictive than those agreed upon in the First
                                Priority Senior Secured Notes Indenture.

Events of Default:              Substantially the same as provided in the
                                existing Senior Notes indenture and otherwise as
                                is typical for similar restructuring
                                transactions, plus cross acceleration to the
                                First Priority Senior Secured Notes.

                                Second Priority Senior Secured Notes shall have
                                a put option whereby such holders shall be
                                entitled to redeem all or any portion of their
                                Second Priority Senior Secured Notes in exchange
                                for payment in cash from SATMEX of one hundred
                                percent (100%) of the sum of the
                                then-outstanding principal amount plus accrued
                                and unpaid interest, which redemption shall be
                                consummated simultaneously with such Change of
                                Control.

                                For purposes hereof, an "APPROVED BUYER" shall
                                mean a Buyer (as defined below) that is, or is
                                controlled by (A) a leading international
                                satellite or telecommunications company having a
                                minimum net worth of one billion dollars (U.S.
                                $1,000,000,000), and/or (B) a person or company
                                listed on Schedule D hereto; provided, however,
                                that (whether or not otherwise qualifying as an
                                Approved Buyer) no person or group may be an
                                Approved Buyer if such person or group, or
                                affiliate thereof, has been indicted for a
                                felony or charged (civilly or criminally) with a
                                violation of securities laws or regulations of
                                the U.S. or Mexico during the preceding five (5)
                                years; and a "BUYER" shall mean a person or
                                group (within the meaning of Section 13(d)(3) of
                                the Securities Exchange Act) that following a
                                Change of Control is the beneficial owner of,
                                and solely controls, shares of SATMEX
                                representing not less than a majority of the
                                equity financial rights of SATMEX and not less
                                than a majority of the equity voting rights of
                                SATMEX (including the right to appoint or elect
                                a majority of the Board of Directors of SATMEX).
                                If the Approved Buyer is a "foreign investor" or
                                its investment in SATMEX would be deemed a
                                "foreign investment" within the meaning provided
                                under the Foreign Investment Law, then the
                                Approved Buyer must be part of a group
                                (constituting a "Buyer" as defined above) with
                                another Approved Buyer

                                      A-13


                                that is not a "foreign investor", nor whose
                                investment in SATMEX would be deemed a "foreign
                                investment" within such meanings.

                                For purposes of the foregoing definitions, (x)
                                the term "CONTROL", when used with respect to
                                any specified person, means the power to direct

                                ownership of voting securities, by contract or
                                otherwise, and the terms "CONTROLLING" and
                                "CONTROLLED" have meanings correlative to the
                                foregoing; (y) the term "PERSON" means any
                                individual, corporation, partnership, joint
                                venture, trust, unincorporated organization or
                                other entity; and (z) a person shall have

                                owner pursuant to Rule 13d-3 under the
                                Securities Exchange Act and shall include,
                                without limitation, any securities such person
                                has the right to become the beneficial owner of
                                (whether or not such right is immediately
                                exercisable) pursuant to any agreement,
                                arrangement or understanding or upon the

                                Default and the affirmative vote of the majority
                                of the holders of the aggregate principal amount
                                of the Second Priority Senior Secured Notes.

                                Technical Committee shall retain one of Credit
                                Suisse, Morgan Stanley, Goldman Sachs, JPMorgan

                                sale as provided above.

                                Any recommendation for the sale of the Trust
                                Shares by the Technical Committee shall be
                                accompanied by a fairness opinion of an Approved
                                Bank that is independent of SATMEX. None of the
                                Trust Shares (or any beneficial ownership in any
                                Series A Shares or the right to vote any Series

                                except in a sale of all of the Trust Shares
                                pursuant to the foregoing procedure.

                                Provided (i) the proposed sale is for 100% of
                                the Trust Shares and the price per share
                                (whether Series A, Series B or Series N) shall
                                be the same, and (ii) the price for the Trust
                                Shares is payable 100% in cash (U.S. dollars),
                                no approval of the beneficial owners of the
                                Trust Shares shall be required for the sale of
                                the Trust Shares; provided, however, that if
                                such sale is consummated, or a binding agreement
                                with respect to such sale is entered into, on or
                                before the second (2nd) anniversary of the
                                Effective Date, the price for 100% of the Trust
                                Shares shall be not less than the amount
                                resulting from a total enterprise value (i.e.,
                                outstanding debt under First Priority Senior
                                Secured Notes and Second Priority Senior Secured

                                dollars (U.S. $500,000,000). If the proposed
                                sale of the Trust Shares does not meet the
                                foregoing conditions, such sale shall be subject
                                to the approval of (i) the Voting Committee and
                                (ii) the SPE which, in turn, will require the
                                affirmative vote of the holders of depository
                                receipts representing not less than 66-2/3% of
                                the Bondholder Equity.

                                Notwithstanding anything to the contrary herein,
                                unless the Buyer is an Approved Buyer (as such
                                terms are defined in Section III), a Change of
                                Control purchase offer for the Second Priority
                                Senior Secured Notes shall be consummated
                                simultaneously with the sale of the Trust Shares
                                as provided above or upon any subsequent Change
                                of Control (provided that such purchase offer
                                requirement may be waived by the vote of holders
                                of 66-2/3% of the aggregate principal amount of
                                the Second Priority Senior Secured Notes).

                                Pending the sale of the Trust Shares, in any
                                matter submitted to the vote of the shareholders
                                of SATMEX, the Trustee shall vote the voting
                                Trust Shares in accordance with the instructions
                                of the respective beneficial

                                      A-19


                                owners of the Trust Shares; provided that with
                                respect to the Servicios Shares such
                                instructions shall be given by the Voting
                                Committee. A committee of three (3) persons (the
                                "VOTING COMMITTEE") will be established under
                                the Equity Trust and pursuant to the quiebra of
                                Servicios for purposes of providing instructions
                                to the Trustee with respect to the voting of the
                                Servicios Shares. The members of the Voting
                                Committee may be the same as the members of the
                                Technical Committee or of the Board of
                                Directors, provided that the initial members of
                                the Voting Committee, and alternates for such
                                members, if any, will be appointed from among
                                the persons listed on Schedule B-1. The initial
                                term of such appointment shall be 2 years, and
                                to the extent necessary, shall renew
                                automatically for an additional term of 2 years.
                                Any subsequent appointment to the Voting
                                Committee shall be approved by the members of
                                the Technical Committee appointed from the list
                                of candidates for Series A Directors. The
                                members of the Voting Committee shall qualify as
                                independent directors (in accordance with
                                Schedule B-2). Notwithstanding the foregoing,
                                the Trust Shares may not be voted in any manner
                                that conflicts with or is inconsistent with the
                                sale or corporate governance provisions
                                described in this Term Sheet.

                                Decisions with respect to the Bondholder Equity
                                (including the voting and disposition of 100% of
                                the Bondholder Equity) will be made by the
                                Trustee upon the affirmative vote of the SPE
                                which, in turn, will require the affirmative
                                vote of the holders of depository receipts
                                representing not less than 66-2/3% of the
                                Bondholder Equity.

                                The Equity Trust may be amended or terminated
                                only with the approval of (i) the Voting
                                Committee and (ii) the SPE which, in turn, will
                                require the affirmative vote of the holders of
                                depository receipts representing not less than
                                66-2/3% of the Bondholder Equity. All beneficial
                                owners of shares in the Equity Trust shall be
                                bound by any such amendment or termination;
                                provided that any amendment having a
                                disproportionate and material adverse impact on
                                the Loral Shares or Principia Shares shall
                                require the approval of the respective
                                beneficial holder of such shares.

Governance of SATMEX:           The by-laws of SATMEX will be revised and
                                simplified, including eliminating existing veto
                                rights afforded to Firmamento, and will also be
                                revised in a manner acceptable to the
                                Bondholders consistent with the voting and
                                governance matters set forth in this Term Sheet,
                                subject to applicable regulatory approvals that
                                do not have a material impact on the provisions
                                herein.

                                To the extent not inconsistent with the terms of
                                this Term Sheet, SATMEX will adopt the
                                principles contained in the Code of Best
                                Corporate Practices (the "PRINCIPLES"), upon the
                                Effective Date.

                                      A-20


Board of Directors:      The Board of Directors of SATMEX will consist of seven
                         (7) members, appointed as follows:

                         (a) the holders of the Series A Shares will appoint
                         four (4) directors, as follows: (i) the Mexican
                         Government will appoint one (1) director, who will be
                         independent and a Mexican national; and (ii) the Voting
                         Committee with respect to the Servicios Shares will
                         appoint three (3) directors, who will be independent
                         and will be Mexican nationals (the "SERIES A
                         DIRECTORS");

                         (b) Principia and Loral Skynet, for so long as they
                         (individually or collectively) collectively
                         beneficially own 100% of the shares of SATMEX held by
                         them as of the Effective Date, will jointly appoint one
                         (1) Series B Director. The Series B Director appointed
                         by Principia and Loral Skynet shall not (i) participate
                         in, or have any access to the minutes of, any
                         discussion or action concerning the sale of SATMEX or
                         the Trust Shares as contemplated herein or (ii) be a
                         member of the Technical Committee or Voting Committee.
                         Notwithstanding the foregoing, such Series B Director
                         shall have such right to participate and to have access
                         (subject to customary standards of recusal in the event
                         of conflict of interest) if Principia and Loral Skynet
                         shall notify the Technical Committee in writing that
                         neither Principia nor Loral Skynet intends to offer or
                         otherwise seek, directly or indirectly, to purchase
                         SATMEX or its assets or the Trust Shares for a period
                         of twelve (12) months thereafter. The Series B Director
                         appointed by Loral Skynet and Principia may participate
                         in, and have access to the minutes of, any discussion
                         or action concerning the Next Satellite procurement by
                         SATMEX (subject to the recusal of the Series B Director
                         from (1) those Board discussions or any vote involving
                         an evaluation of proposals submitted in response to
                         Satmex's RFP for the Next Satellite and (2) the
                         decision as to which manufacturer will be awarded the
                         contract for the Next Satellite).

                         (c) the Bondholder Equity will appoint two (2)
                         directors (together with the director appointed
                         pursuant to clause (b) above, the "SERIES B
                         DIRECTORS"). In the event Principia and Loral Skynet
                         shall no longer (individually or collectively)
                         beneficially own 100% of the shares of SATMEX held by
                         them as of the Effective Date, the Bondholder Equity
                         may remove the Series B Director appointed by Principia
                         and Loral Skynet pursuant to clause (b) above, and
                         thereafter the Bondholder Equity will appoint such
                         third Series B Director.

                         The Series B Shares will be entitled to appoint the
                         Secretary of the Board of Directors, and will also have
                         the right to appoint a Statutory Auditor (Comisario).
                         Unless otherwise specified by the Bondholder Equity,
                         the Secretary and the Statutory Auditor shall be the
                         persons specified on Schedule B-1.

                                      A-21


                         Director independence will be determined in accordance
                         with the principles set forth on Schedule B-2.

                         The Audit Committee and the Compensation Committee (or
                         a single committee, if permitted by applicable law)
                         each will be comprised of three persons, consisting
                         initially of two Series A independent directors and one
                         Series B Director designated by the Bondholder Equity
                         (which may be the Series B Director appointed by
                         Principia and Loral Skynet if so designated by the
                         Bondholder Equity and such designation is accepted by
                         such Director). Each of such committee member shall be
                         independent within the meaning of Section 10A(m)(3) of
                         the Securities Exchange Act. If the Board of Directors
                         determines to increase the size of such committee(s),
                         the Series B Director appointed by Principia and Loral
                         Skynet shall not be precluded from serving on such
                         committee(s). In any event, all committees of the Board
                         will include at least one Series B Director appointed
                         by the Bondholder Equity. The initial members of the
                         Board of Directors shall be appointed from among the
                         persons listed on Schedule B-1. The term of each
                         director shall be renewed automatically from year to
                         year, unless replaced by the holders of the shares that

                         shall be appointed by the holders of the shares that
                         first appointed such directors, except that, in the
                         case of directors appointed by the Voting Committee,
                         such removal, replacement or appointment shall be made

Quorum and Voting;
Extraordinary Matters:   Other than for Extraordinary Matters (as defined
                         below), a quorum of the Board shall be a majority of
                         the Board including a minimum of two Series B
                         Directors, unless such Series B Directors fail to be
                         present after a first call, in which case a quorum
                         shall be a majority of the Board with or without such
                         Series B Directors. For Extraordinary Matters, a quorum
                         requires a majority of the Board, including a majority
                         of the Series B Directors.

                         Actions of the Board shall require a majority vote,
                         provided that the approval of two Series A Directors
                         and two Series B Directors shall be required for
                         Extraordinary Matters. If an Extraordinary Matter is
                         submitted to the Board for consideration, but such
                         matter fails to obtain the required approval as
                         described above, the Extraordinary Matter can
                         nevertheless be approved by the shareholders of SATMEX
                         but only through an Extraordinary Shareholders Meeting
                         and only if such matter has been approved by the
                         affirmative vote of at least 75% of all of the voting
                         stock of SATMEX.

                         If an Extraordinary Matter is required by law or the
                         by-laws of SATMEX to be submitted to the shareholders
                         for consideration, such Extraordinary Matter shall be
                         submitted to an Extraordinary Shareholders Meeting and
                         will require approval by the affirmative vote of at
                         least 75% of all of the voting stock of SATMEX.

                         Resolutions taken by an Extraordinary Shareholders
                         Meeting on first or subsequent call shall be valid if
                         approved by the affirmative vote of at least 75% of all
                         of the voting stock of SATMEX.

                         "EXTRAORDINARY MATTERS" shall be the matters set forth
                         on Schedule C. The sale of the Trust Shares in
                         accordance with the provisions set forth above shall
                         not be an Extraordinary Matter.

Management; Appointment
of Officers:             The CEO of SATMEX shall be appointed by the holders of
                         the Series A Shares (or the Series A Directors), and,
                         to the extent required by law, must be a Mexican
                         national. The CFO of SATMEX shall be appointed from a
                         list of nominees submitted by a majority of the holders
                         of the Series B Shares (or by a majority of the Series
                         B Directors). All other officers to be mutually agreed
                         upon by the Series A Directors and Series B Directors,
                         except that the COO of SATMEX (to the extent such
                         officer is deemed by the Board of Directors to be
                         necessary) will be appointed from a list of nominees
                         submitted by a majority of the holders of the Series B
                         Shares (or by a majority of the Series B Directors).

Foreign Investment Law:  Series A Shares shall constitute at all times at least
                         51% of the voting stock of SATMEX and shall be held
                         exclusively by Mexican nationals in accordance with the
                         Foreign Investment Law. Series B Shares and Series

                                      A-23


                         N Shares may be held by non-Mexicans. The Series B
                         Shares will be full voting shares and the Series N
                         Shares will be neutral nonvoting shares.

                         In the event Mexican law changes to permit voting
                         majority ownership of SATMEX by non-Mexicans, then,
                         within one (1) year after the enactment of such change,
                         the Series N Shares issued as part of the Bondholder
                         Equity will be converted into full voting Series B
                         Shares, such that the equity voting rights in SATMEX
                         will be in the same percentages as the equity financial
                         rights in SATMEX. In such event, the majority of the
                         Board of Directors will be appointed by a majority of
                         the Series B Shares.

Approvals:               SATMEX and its shareholders, together with the
                         Conciliador, shall use commercially reasonable efforts
                         to obtain all governmental approvals required in
                         connection with the transactions contemplated in this
                         Term Sheet, including approvals of the Ministry of
                         Communications and Transportation, Foreign Investment
                         Commission, Federal Competition Commission, CNBV and
                         the U.S. Federal Communications Commission.

Service                  Companies: The shares of the three services companies
                         where all SATMEX personnel are currently lodged will be
                         transferred for nominal consideration and will become
                         subsidiaries of SATMEX on the Effective Date;
                         alternatively, all such personnel will be transferred
                         to SATMEX or to one or more wholly-owned subsidiaries

                         compensation to be continued, as required by Mexican
                         labor law).

Transferability:         The issuance of the depository receipts representing
                         the beneficial ownership of the Trust Shares that
                         constitute the Bondholder Equity shall be exempt from
                         registration under the Securities Act pursuant to
                         Section 1145 of the Bankruptcy Code. Bondholders that

                         granted demand registration rights to require SATMEX to
                         file a registration statement on Form F-1 (or Form F-3,
                         if such form may then be utilized by SATMEX) with the

                         resale any equity securities (e.g., depository

                         above). Mandatory periodic reporting requirements in

                         addition to the statutory requirement under Mexican

                         internationally-recognized Mexican bank for payment of
                         bonuses equal to the total of all amounts listed on

                        DESCRIPTION OF SILENT SECOND LIEN
                     OF SECOND PRIORITY SENIOR SECURED NOTES

Collateral:              SATMEX's obligations to pay interest and principal when
                         due on the First Priority Senior Secured Notes and
                         Second Priority Senior Secured Notes will be secured by
                         separate liens on all present and after acquired assets
                         of SATMEX and any Restricted Subsidiaries except as
                         provided for in Section I of this Term Sheet under the
                         caption "Loral Transponders" (the "SHARED COLLATERAL").

Ranking:                 Without giving effect to the liens on the Shared
                         Collateral, the First Priority Senior Secured Notes and
                         the Second Priority Senior Secured Notes will rank pari
                         passu in right of payment to all existing and future
                         senior indebtedness of SATMEX and any Restricted
                         Subsidiaries, and will rank senior to all existing and
                         future subordinated indebtedness of SATMEX, subject to
                         any priorities recognized by statute, such as tax and
                         labor obligations.

Lien Subordination:      The Second Priority Senior Secured Notes will be junior
                         in priority, operation and effect at all times and
                         under all circumstances to the security interests of
                         the First Priority Senior Secured Notes and any
                         enforcement of the second priority lien and any payment
                         of the Second Priority Senior Secured Notes from the
                         collateral securing the Second Priority Senior Secured
                         Notes shall be subject to the prior payment in full of
                         the First Priority Senior Secured Notes. Subject to
                         Section I of this Term Sheet under the caption "Loral
                         Transponders", the proceeds of the Shared Collateral
                         will be applied to satisfy all outstanding obligations
                         under the First Priority Senior Secured Notes prior to
                         any proceeds being applied to any obligations under the
                         Second Priority Senior Secured Notes. The First
                         Priority Senior Secured Notes and the Second Priority
                         Senior Secured Notes will be structurally senior to all
                         unsecured indebtedness of SATMEX by virtue of their
                         lien rights.

Collateral Trustee:      The respective trustees under the indentures
                         governing the First Priority Senior Secured Notes and
                         the Second Priority Senior Secured Notes will each be
                         granted a security interest in the Shared Collateral
                         and the indenture trustees shall enter into an
                         intercreditor agreement containing the terms set forth
                         herein (the "INTERCREDITOR AGREEMENT").



Prohibition on Liens:    The indenture governing the Second Priority
                         Senior Secured Notes will prohibit SATMEX or any
                         guarantor from granting or suffering to exist any lien
                         on the Shared Collateral other than liens securing:

                         -  the First Priority Senior Secured Notes and any
                            refinancing thereof;

                         -  the Second Priority Senior Secured Notes and any
                            refinancing thereof;

                         -  taxes, assessments or other governmental charges or
                            levies not yet delinquent or which are being validly
                            contested in good faith;

                         -  carriers', warehousemen's, mechanics', laborers' or
                            similar liens arising in the ordinary course of
                            business and securing obligations that are not yet
                            due and payable or that are being contested in good
                            faith and in respect of which SATMEX will have set
                            aside on its books reserves;

                         -  purchase money liens to finance the acquisition of
                            assets in the ordinary course of business so long as
                            such lien is limited to the assets so acquired, the
                            indebtedness does not exceed the purchase price and
                            such lien exists at the time of the acquisition or
                            will be created within 180 days of such acquisition;
                            and

                         -  other customary permitted liens.

Refinancing:             Notwithstanding anything to the contrary herein, SATMEX
                         will be permitted to refinance each of the First
                         Priority Senior Secured Notes and the Second Priority
                         Senior Secured Notes, provided that (i) the aggregate
                         principal amount outstanding after such refinancing is
                         not greater than the aggregate amount of all
                         obligations outstanding immediately prior to such
                         refinancing with respect to the obligations being
                         replaced, (ii) such refinancing shall not have a
                         shorter Average Life (as defined below) as compared
                         with the indebtedness being replaced, and (iii) the
                         interest rate and the cash interest payment terms on
                         such refinancing shall not be greater or more favorable
                         to the holders of such refinancing debt than the
                         interest rate and the cash interest payment terms on
                         the respective debt being refinanced unless such
                         greater or more favorable terms are commercially
                         reasonable at the time of such refinancing. "Average
                         Life" shall have the meaning set forth in the current
                         Senior Notes indenture without regard to any mandatory
                         prepayments. Any such refinancing debt will be entitled
                         to the same benefits, waivers and priority provided
                         under this Term Sheet to the debt being refinanced and
                         subject to the same burdens provided under this Term
                         Sheet, as applicable. The Available Cash Flow Repayment
                         Formula shall apply to any refinancing debt in
                         accordance with the terms of the debt being refinanced.

                                       2



Release of Collateral:   The lien of the Second Priority Senior Secured Notes
                         will be automatically released upon the foreclosure or
                         sale of any Shared Collateral by the holders of the
                         First Priority Senior Secured Notes in accordance with
                         the First Priority Senior Secured Notes Indenture,
                         provided that proceeds from such sale shall be applied
                         in accordance with the Intercreditor Agreement and the
                         respective Indentures. Notwithstanding the foregoing,
                         the holders of the Second Priority Senior Secured Notes
                         will not be permitted to object to any bankruptcy court
                         or concurso mercantil ordered sale of the Shared
                         Collateral that has been approved by the holders of the
                         First Priority Senior Secured Notes provided that the
                         lien of the Second Priority Senior Secured Notes
                         attaches to the proceeds of any such sale in accordance
                         with the priorities set forth in the Intercreditor
                         Agreement. In the event that any concurso mercantil
                         proceeding is filed in Mexico, the liens in favor of
                         the Second Priority Senior Secured Notes may be
                         released by the Common Representative (as defined
                         below) with the approval of the holders of more than
                         50% in principal amount of the outstanding Second
                         Priority Senior Secured Notes, with such release to be
                         effective as of immediately prior to the commencement
                         of the concurso mercantil.

Common Representative:   A common representative shall be irrevocably appointed
                         under Mexican law to act for the benefit of 100% of the
                         holders of the Second Priority Senior Secured Notes
                         (the "COMMON REPRESENTATIVE") solely for the purposes
                         of (i) voting in favor of or accepting a plan of
                         reorganization in any future concurso mercantil
                         proceeding, (ii) exercising all veto rights in
                         connection with the approval of such concurso plan in
                         Mexico, but only in the event that such plan is
                         accepted by holders of a majority of the aggregate
                         outstanding principal amount of the Second Priority
                         Senior Secured Notes, and (iii) releasing liens as
                         described in the immediately preceding section.

                         First Priority Senior Secured Notes have been paid in
                         full, the Second Priority Senior Secured Notes will be

                            Shared Collateral, and the Second Priority Senior
                            Secured Notes will not contest any actions taken by
                            the holders of the First Priority Senior Secured
                            Notes with respect to Shared Collateral,

                            cause the indenture trustee for the Second Priority
                            Senior Secured Notes to seek a junior lien on any
                            assets on which the United States bankruptcy court
                            grants a lien as adequate protection to secure the
                            First Priority Senior Secured Notes, so long as (i)
                            the junior lien is subject to the same lien
                            subordination arrangements as set forth in the

                            claims arising by virtue of such liens unless the
                            First Priority Senior Secured Notes have been paid

                                     ANNEX F

                           CONFIDENTIALITY PROVISIONS

The provisions hereof (this "Annex") shall govern with respect to the
Confidential Information as described in section 5(b) of the Agreement.
Capitalized terms not defined herein shall have the meanings given to them in
the Agreement.

      1. (a) The term "Confidential Information" has the meaning set forth in
      section 5(b) of the Agreement. The term "Confidential Information" shall
      not include information: (i) that is or becomes generally available to the
      public (including any information contained in a press release issued
      pursuant to section 30 of the Agreement) or to a recognized creditor in
      connection with the Concurso Proceeding other than as a result of a breach
      of section 5(b) of the Agreement and this Annex; (ii) that is already in
      the possession of a Recipient without, to the knowledge of such Recipient,
      restriction or (iii) that is or has been disclosed to a Recipient by a
      third party, not employed by or otherwise affiliated with such Recipient,
      who is, to the knowledge of such Recipient, after reasonable inquiry, not
      prohibited from disclosing such information to such Recipient.

      (b) The term "Recipient" means any Supporting FRN Holder or any Supporting
      Noteholder.

      (c) The term "Representatives" means, with respect to any Recipient, its
      affiliates, its subsidiaries, its related or associated entities, or its
      or their directors, members, officers, affiliates, partners, employees,
      agents, advisers or representatives, including, without limitation,
      attorneys, accountants, consultants, bankers, financial advisers and any
      representatives of such advisers.

2. Confidential Information may be disclosed:

            (a) as permitted by Paragraph 4 below;

            (b) if approved by the Company in writing prior to its disclosure or
      use; and

            (c) if required by law, regulation, regulatory authority or other
      applicable judicial or governmental order or process (including any
      discovery request) or any governmental authority, or any "self regulatory
      organization" as defined in section 3(a)(26) of the Securities Exchange
      Act of 1934, as amended, or any successor act; provided, however, each
      Recipient that is so required, will use its commercially reasonable
      efforts to provide the Company with prompt notice of such request or
      requirement so that the Company may at its election and sole expense seek
      a protective order or other appropriate remedy and such Recipient and its
      Representatives will, at the Company's sole expense, reasonably cooperate
      with the Company's efforts to obtain the same. If, absent the entry of
      such a protective order or other remedy, such Recipient or its
      Representative is,



      upon the advice of its counsel, compelled to disclose Confidential
      Information, such Recipient or its Representative may disclose that
      portion of the Confidential Information that such Recipient or its
      Representative believes on the advice of counsel that it is compelled to
      disclose.

3. Confidential Information may be used by any Recipient and its Representatives
in any discussions or negotiations with any other Recipient (and their
Representatives) or any holder of the Company's Securities (and its
Representatives) that is a party to the Agreement, the Conciliador, or the
government of Mexico, provided that the Recipient's discussion or negotiation
which may include Confidential Information does not render such Confidential
Information public and such discussion or negotiation of Confidential
Information shall be treated as Confidential Information pursuant hereto.

4. Each Recipient may disclose Confidential Information only to (i) its
Representatives on a need to know basis and in connection with the Restructuring
(and the Recipient agrees to be liable for any breaches of this Agreement by its
Representatives) and (ii) any Recipient or any other holder of the Debt that has
signed a confidentiality agreement acceptable to the Company. Notwithstanding
anything contained herein to the contrary, a Recipient may disclose to (i) any
third party that the Recipient has signed the Agreement and may be in possession
of material nonpublic information, (ii) to any member of any of the Committees
that the Recipient has signed this Agreement and that the Recipient may be in
possession of material nonpublic information, in each case without revealing any
Confidential Information and (iii) to any transferee of Securities in accordance
with section 5(c) of the Agreement. In any event, each Recipient shall maintain
a list of those of its Representatives or other persons to whom Confidential
Information has been disclosed (which list shall be presented to the Company on
request).

5. Each Recipient acknowledges that it has been advised by the Company and/or
its Representatives that the Confidential Information includes information that
may be material, nonpublic and highly confidential. The Company has been advised
that any Recipient may establish an information blocking device or "Ethical
Wall" between such Recipient's employees who receive the Confidential
Information and its other employees. The Company expressly takes no position on
the propriety of any such arrangement under applicable securities laws and
regulations and each Recipient agrees that it shall at all times comply with all
state and federal securities laws and regulations. Each Recipient agrees that,
in the event it establishes such an information blocking device or Ethical Wall,
that it will designate to the Company in writing the employees who, pursuant to
the Ethical Wall, are permitted to receive information or otherwise participate
in discussions concerning the Restructuring (the "Designated Representatives").
In order to preserve such Ethical Wall, if established (and without limiting the
generality of other provisions of this Agreement), each Recipient agrees that
the Designated Representatives shall not disclose Confidential Information to,
or otherwise discuss any matter concerning or relating to the Restructuring
with, any employee or director of the Recipient or the Recipient's affiliates
who is not a Designated Representative. The Company acknowledges that the
Recipients have disclosed that, in the event an Ethical Wall is established,
funds and accounts managed by a Recipient and its affiliates that are not



advised, directly or indirectly, by any Designated Representative may from time
to time purchase, hold or dispose of securities issued by the Company or its
affiliates during or after the term hereof. Each Recipient acknowledges that the
Company has not taken a position regarding the propriety of any such purchase,
retention or disposition of such securities under applicable securities laws and
regulations. Nothing contained in this Annex shall be deemed to restrict or
impair a Recipient's ability to purchase, hold or dispose of securities issued
by the Company or its affiliates in accordance with applicable securities laws
during or after the term hereof.

6. The obligations of each Recipient under section 5(b) of the Agreement and
this Annex shall terminate on the earliest of (a) the termination of the
Agreement as to such Recipient or (b) the date that the Disclosure Statement is
filed by the Company with the Bankruptcy Court (the "Disclosure Date"). Upon the
Disclosure Date (unless the Disclosure Date is pursuant to (b) above), the
Company shall promptly file an appropriate summary of the Confidential
Information, on Form 6-K or other periodic report required or permitted to be
filed under the Securities Exchange Act of 1934, as amended, with the Securities
and Exchange Commission. In the event the Company fails to make a filing of the
type prescribed in the foregoing sentence within five business days of the
Disclosure Date, any Recipient, any Recipient's Representatives or the
Recipients as a group, are hereby authorized to disclose publicly the
Confidential Information. If, upon the advice of counsel, any filing by the
Company made within such five business day period is insufficient to unrestrict
the Recipients, the Recipients or their Representatives shall so notify the
Company in writing, which notice shall set forth why the Recipient considers the
Company's public disclosure insufficient and what disclosure it feels is
required. If, within three business days of its receipt of such notice, the
Company and the Recipients do not agree on the nature or extent of the
disclosure required pursuant hereto, the Recipients are hereby authorized to
disclose publicly the Confidential Information, to the extent the Recipient on
the advice of counsel believes it is necessary to remedy the alleged
insufficiency of the Company's prior public disclosure. Each Recipient
acknowledges and agrees that its sole remedy for the Company's failure to make a
public filing as required pursuant to this Paragraph 6 is the remedy of public
disclosure by the Recipient as is expressly provided for in this Paragraph 6.

     2. Satmex may not, and waives any right to, reject the Loral Settlement
Agreements, whether in the 304 Proceeding or any case under chapter 11 of the
Bankruptcy Code (the "Chapter 11 Case"), in connection with the Restructuring or
otherwise.

     3. No injunction entered in this 304 Proceeding shall be more restrictive
as against the Loral Entities than those injunctions issued pursuant to Orders
entered in the Satmex Involuntary Case dated August 8, 2005 [Docket No. 11],
October 19, 2005 [Docket No. 17] and January 11, 2006 [Docket No. 19].


                                       5



     4. Satmex shall file a motion in the Chapter 11 Case seeking assumption of
the Loral Settlement Agreements within five (5) days after the commencement of
the Chapter 11 Case and there shall be a final and non-appealable order (the
"Assumption Order") assuming such Loral Settlement Agreements in the Chapter 11
Case by no later than July 24, 2006 (time being of the essence).

     5. The Automatic Stay in the Chapter 11 Case automatically and without any
further action or filing is and shall be waived, modified and lifted immediately
upon commencement of the Chapter 11 Case to permit the Loral Entities to
exercise all of their rights and remedies under the Loral Settlement Agreements.
The Parties to this Stipulation, Agreement and Order enter into this waiver
knowingly and intelligently and are estopped from contesting its validity. From
the date hereof and terminating upon entry of the Assumption Order, the Loral
Entities shall provide five (5) business days' advance notice of an exercise of
any of their termination rights under the Loral Settlement Agreements to (a)
Satmex and its undersigned counsel, (b) Wilmer Cutler Pickering Hale and Dorr
LLP (Attn: George W. Shuster, Jr.) as counsel to FRNs, (c) Akin Gump Strauss
Hauer & Feld LLP (Attn: Steven H. Scheinman) as counsel to the Ad Hoc Committee
of Senior Noteholders, and (d) Nixon Peabody, LLP (Attn: Frank S. Hamblett), as
counsel to Citibank, N.A. as Indenture Trustee for the FRNs. To the extent the
Automatic Stay is implicated other than as provided in this paragraph, the
provisions of the Automatic Stay, including, without limitation, those
provisions prohibiting any act to collect, assess or recover a claim that arose
before the commencement of a Chapter 11 Case and/or assets or property of
Satmex's estate (as defined in section 541 of the Bankruptcy Code) shall remain
in full force and effect.


                                        6



     6. Upon execution by Satmex, the Supporting Debtholders and the Loral
Entities, the terms and provisions of this Stipulation, Agreement and Order are
fully binding, effective and enforceable against the Parties hereto and
effectiveness hereof is not subject to the approval of the Court.

     7. For the avoidance of doubt, nothing herein shall obligate Satmex to
commence a case under chapter 11 of the Bankruptcy Code.

     8. This Stipulation, Agreement and Order shall be binding on all successors
and assigns of the Parties hereto.

     9. This Stipulation, Agreement and Order shall be governed by the laws of
the State of New York.

     10. Each person who executes this Stipulation, Agreement and Order
represents that he or she is duly authorized to execute this Stipulation,
Agreement and Order on behalf of the respective Parties hereto and that each
such party has full knowledge of and has consented to the terms and provisions
hereof.

     11. This Stipulation, Agreement and Order may be executed in counterparts,
each of which shall be deemed an original but all of which together shall
constitute one and the same instrument and it shall constitute sufficient proof
of this Stipulation, Agreement and Order to present any copy, copies or
facsimiles signed by the Parties hereto to be charged.


                                       7



     12. This Stipulation, Agreement and Order can only be amended or otherwise
modified by a writing executed by the Parties hereto.
