      included as part of the Collateral), the right to recover for all past,
      present and future infringements thereof, all other rights of any kind
      whatsoever accruing thereunder or pertaining thereto, in each case, only
      to the extent that such trade names, trademarks, service marks, logos,
      registrations, applications and other rights are actually included in the

transfer to the Secured Party, or a restriction on the Obligors' use of, any
cash Collateral (other than cash proceeds from the Insurance Policies, which
shall be governed by Section 4.04(e)) of this Agreement, other than during a
period during which a Security Event of Default has occurred and is continuing.

                                   ARTICLE IV

                         COVENANTS AND OTHER AGREEMENTS

In furtherance of the grant of the pledge, charge and security interest pursuant
to Article III and subject to Article V, the Obligors hereby jointly and
severally agree with the Secured Party as follows:

      SECTION 4.01. Delivery and Other Perfection. Each Obligor shall:

      (a) if any of the shares, interests, securities, moneys or property
      required to be pledged or charged by such Obligor under clauses (a), (b)
      and (c) of Article III are received by such Obligor, promptly either (i)
      transfer and deliver to the Secured Party such shares or securities so
      received by such Obligor (together with the certificates for any such
      shares and securities duly endorsed in blank or accompanied by undated
      stock powers or share transfer forms duly executed in blank), all of which
      thereafter shall be held by the Secured Party pursuant to the terms of
      this Agreement, as part of the Collateral, (ii) with respect to any
      Pledged Collateral that is not evidenced by a certificate, execute and
      deliver written instructions to the issuer thereof to register the
      security interest created hereunder in such Pledged Collateral in the
      registration books maintained by such issuer for such purpose and cause
      the respective Obligor to execute and deliver to the Secured Party a
      written confirmation to the effect that the security interest created
      hereunder in such Pledged Collateral has been duly registered in such
      registration books, all in form and substance satisfactory to the Secured
      Party or (iii) take such other action as the Secured Party shall
      reasonably deem necessary or appropriate to duly perfect the security
      interest created hereunder in such shares, interests, securities, moneys
      or property in said clauses (a), (b) and (c);

      (b) deliver, assign and pledge to the Secured Party any and all
      Instruments included in the Collateral, endorsed and/or accompanied by
      such instruments of assignment and transfer in such form and substance as
      the Secured Party may reasonably request; provided that so long as no
      Security Event of Default shall have occurred and be continuing, such
      Obligor may retain for collection in the ordinary course any Instruments,
      Accounts or General Intangibles received by such Obligor and the Secured
      Party shall, promptly upon request of such Obligor, make appropriate
      arrangements for making any Instrument pledged or assigned by such Obligor
      available to such Obligor for purposes of presentation, collection or
      renewal (any such arrangement to be effected, to the extent reasonably
      deemed appropriate by the Secured Party, against a trust receipt or like
      document);

      (c) give, execute, deliver, file and/or record any financing statement,
      form, notice, instrument, document, agreement or other papers that may be
      necessary or desirable (in the reasonable judgment of the Secured Party)
      to create, preserve, perfect or validate the security interest granted
      pursuant hereto or to enable the Secured Party to
<PAGE>
      ensure the priority of, or exercise and enforce its rights hereunder with
      respect to, such pledge, charge and security interest (it being understood
      that the provisions of this Section will apply to all Collateral, whether
      personal property or real property, whether tangible or intangible, and
      wherever located and whenever acquired, including, without limitation,
      Collateral located outside the United States or in space), including,
      without limitation, when a Security Event of Default has occurred and is
      continuing, but subject to receipt of required regulatory approvals (which
      each Obligor shall use its best efforts to obtain and maintain in effect)
      causing any or all of the Pledged Collateral to be transferred of record
      into the name of the Secured Party or its nominee (and the Secured Party
      agrees that if any Pledged Collateral is transferred into its name or the
      name of its nominee, the Secured Party will thereafter promptly give to
      the respective Obligor copies of any notices and communications received
      by it with respect to the Pledged Collateral pledged or charged by such
      Obligor hereunder), provided that notices to account debtors or
      unaffiliated parties in respect of any Accounts, Instruments or other
      Collateral referred to in clause (i) of Article III shall be subject to
      the provisions of clause (h) below;

      (d) keep full and accurate books and records in accordance with generally
      accepted business practices relating to the Collateral, and stamp or
      otherwise mark such books and records in such manner as the Secured Party
      may reasonably require in order to reflect the security interests granted
      by this Agreement;

      (e) upon reasonable notice, at any time during normal business hours,
      permit representatives of the Secured Party to (i) inspect and make
      abstracts from its books and records pertaining to the Collateral, and
      (ii) be present at such Obligor's place of business to receive copies of
      all communications and remittances relating to the Collateral, and forward
      copies of any material notices or. material communications received by
      such Obligor with respect to the Collateral, all in such manner as the
      Secured Party may reasonably require; provided, however that no Obligor
      shall be obligated to disclose any competitively sensitive information
      other than during the period in which a Security Event of Default has
      occurred and is continuing;

      (f) (i) maintain the Launch Insurance in full force and effect, (ii) upon
      the expiry of Launch Insurance, cause "in orbit" coverage (with such
      exclusions as the Obligors deem in good faith to be appropriate) to be
      maintained on the EDS Satellite at least equal to the amount of the
      Secured Obligations, if such coverage is available on commercially
      reasonable terms as determined in good faith by the Obligors (such "in
      orbit" coverage, together with the Launch Insurance, the "Insurance
      Policies"), and (iii) designate prior to the date hereof and thereafter
      maintain (pursuant to endorsements or other documents appropriate for the
      purpose) the Secured Party as a loss payee in respect of all Insurance
      Policies (to the extent of its interest therein with respect to the
      Secured Obligations) and, in connection therewith, providing that the
      first $50 million (or such lesser- amount as may then constitute Secured
      Obligations) be paid directly and solely to the Secured Party as set forth
      in Section 4.04(e) of this Agreement; provided that at any time when the
      Secured Obligation shall be less than the amount for which the Secured
      Party has been so designated a loss payee, the Secured Party will
      cooperate with the Obligors to amend such endorsements or other documents
      to reduce such amount to an amount equal to the then outstanding Secured
      Obligations;

      (g) within twenty (20) days after the end of each calendar quarter,
      provide health status reports for the EDS Satellite to the Secured Party
      as of the last day of such quarter, summarizing all spacecraft related
      incidents and anomalies known to the Obligors and the status of the
      subsystems on the EDS Satellite; and

      (h) upon the occurrence and during the continuance of any Security Event
      of Default, upon request of the Secured Party, promptly notify (and such
      Obligor hereby authorizes the Secured Party so to notify) each account
      debtor in respect of any Accounts or Instruments that such Collateral has
      been assigned to the Secured Party hereunder, and that any payments due or
      to become due in respect of such Collateral are to be made directly to the
      Secured Party to be applied to the payment of the Secured Obligations.

      SECTION 4.02. Other Financing Statements and Encumbrances. Without the
prior written consent of the Secured Party, no Obligor shall authorize to be
filed, in any jurisdiction, any financing statement or like instrument with
respect to the Collateral in which the Secured Party is not named as the sole
secured party except as to Permitted Liens.

      SECTION 4.03. Preservation of Rights. The Secured Party shall not be
required to take steps necessary to preserve any rights against prior
parties to any of the Collateral.

      SECTION 4.04. Special Provisions Relating to Certain Collateral.
<PAGE>
      (a) Pledged Collateral.

      (i) So long as no Security Event of Default shall have occurred and be
continuing, the Obligors shall have the right to exercise all voting, consensual
and other powers of ownership pertaining to the Pledged Collateral, provided
that each Obligor agrees that it will not vote the Pledged Collateral pledged or
charged by it hereunder in any manner that is in violation of the terms of the
Security Documents; and the Secured Party shall execute and deliver to the
Obligors or cause to be executed and delivered to the Obligors all such proxies,
powers of attorney, dividend and other orders, and all such instruments, without
recourse, as the Obligors may reasonably request for the purpose of enabling the
Obligors to exercise the rights and powers that they are entitled to exercise
pursuant to this paragraph (a)(i).

      (ii) Nothing in this Agreement shall restrict any Subsidiary of any
Obligor set forth in Annex 2 from declaring and paying to any Obligor any
dividends or distributions in respect of its ownership interests held by the
Obligor, provided that following the occurrence and during the continuance of a
Security Event of Default all such dividends and distributions shall be paid
directly to a segregated interest-bearing cash collateral account established by
and in the name of the Secured Party (for the benefit of such Obligor) and shall
be held therein as additional Collateral hereunder. If, notwithstanding the
foregoing, such dividends or distributions shall be paid to any Obligor
following the occurrence and during the continuance of a Security Event of
Default, the same shall be held by such Obligor in trust for the Secured Party
and the other Secured Party, segregated from the other funds of such Obligor,
and promptly turned over to the Secured Party for deposit into the aforesaid
account.

      (b) Assigned and Other Agreements. Anything herein to the contrary
notwithstanding, each Obligor party to any Assigned Agreement or other relevant
agreement shall remain liable under such Assigned Agreement or other agreement
to the extent set forth therein to perform all of its duties and obligations
thereunder to the same extent as if this Agreement had not been executed. The
exercise by the Secured Party of any of the rights hereunder shall not release
any Obligor from any of its duties or obligations under any Assigned Agreement
or any such other agreement, except to the extent provided therein or any
consent and agreement relating thereto and upon foreclosure and assignment of
such Assigned Agreement. The Secured Party shall have no obligation or liability
under any Assigned Agreement or such other agreement, by reason of the existence
of this Agreement, nor shall the Secured Party be obligated to perform any of
the obligations or duties of any Obligor thereunder or to take action to collect
or enforce any claim for payment assigned hereunder, except to the extent
provided therein or any such consent and agreement. If any Obligor fails to
perform any agreement contained herein or in any of the Assigned Agreements or
other agreements constituting part of the Collateral required to be performed by
such Obligor, within 30 days after receipt by the Seller of written notice from
the Secured Party informing it of such failure, the Secured Party may itself
perform, or cause the performance of, such agreement, and the expenses of the
Secured Party incurred in connection therewith shall be payable by the Company
and shall be Secured Obligations entitled to the benefits of the collateral
security provided pursuant to Article III.

      (c) Intellectual Property.

      (i) For the purpose of enabling the Secured Party to exercise rights and
remedies under Section 5.01 at such time as the Secured Party shall be lawfully
entitled to exercise such rights and remedies, and for no other purpose, each
Obligor hereby grants to the Secured Party, to the extent assignable, an
irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to such Obligor) to use, assign, license or sublicense any of
the Intellectual Property now owned or hereafter acquired by such Obligor,
wherever the same may be located, including in such license reasonable access to
all media in which any of the licensed items may be recorded or stored and to
all computer programs used for the compilation or printout thereof.

      (ii) Notwithstanding anything contained herein to the contrary, so long as
no Security Event of Default shall have occurred and be continuing, the Obligors
will be permitted to exploit, use, enjoy, protect, license, sublicense, assign,
sell, dispose of or take other actions with respect to the Intellectual Property
in the ordinary course of the business of the Obligors. In furtherance of the
foregoing, unless a Security Event of Default shall have occurred and be
continuing the Secured Party shall from time to time, upon the request of the
respective Obligor through the Company, execute and deliver any instruments,
certificates or other documents, in the form so requested, that such Obligor
through the Company shall have certified are appropriate (in their judgment) to
allow them to take any action permitted above (including relinquishment of the
license provided pursuant to paragraph (i) immediately above as to any specific
Intellectual Property). Further, upon the
<PAGE>
payment in full of all of the Secured Obligations and cancellation or
termination of the Commitments or earlier expiration of this Agreement or
release of the Collateral, the Secured Party shall grant back to the Obligors
the license granted pursuant to said paragraph (i). The exercise of rights and
remedies under Section 5.01 by the Secured Party shall not terminate the rights
of the holders of any licenses or sublicenses theretofore granted by the
Obligors in accordance with the first sentence of this paragraph (ii).

      (iii) The security interests granted by each Obligor hereunder in
Intellectual Property are intended to assure the ownership, operation,
exploitation and use of the EDS Satellite by Secured Party or any transferee
following foreclosure, and the Secured Party shall not have any right to sell or
otherwise transfer any Intellectual Property independently of a transfer of the
EDS Satellite to a buyer on foreclosure. In addition, so long as the foregoing
license to the Intellectual Property is available to assure the effective
ownership, operation, exploitation and use of the EDS Satellite, neither the
Secured Party nor any successor shall have any right to acquire ownership
thereof.


      (d) EDS Satellite. Each Obligor agrees and acknowledges that (i) the
Collateral includes a pledge by the Seller of the EDS Satellite, (ii) that the
Secured Party intends to perfect its security interest in and security interest
on such satellite, (iii) that the Obligors anticipate that, in due course,
ownership of the EDS Satellite is expected to be sold by Seller to Skynet and by
Skynet to SkynetBrazil, and (iv) that any such sale of the EDS Satellite is and
shall at all times be permitted pursuant to the terms hereof, provided, however,
that any transfer thereof shall be fully subject, in all respects, to the
Secured Party's continuing security interest therein until released upon the
payment and performance in full of all Secured Obligations.

      Without limiting in any respect any other provisions of this Agreement,
each Obligor agrees to assist the Secured Party in achieving and maintaining
perfection of its security interest in the EDS Satellite through whatever method
or methods the Secured Party may from time to time reasonably request, including
(i) filing UCC financing statements on the basis that satellites constitute
"mobile goods" under the Uniform Commercial Code, (ii) filing UCC financing
statements or other security interest perfection documents in each jurisdiction
in which the satellite is manufactured, integrated or processed, from where any
satellite is launched, from where it is controlled or in which it may from time
to time be deemed located to the extent such filing in such jurisdiction is
reasonably required in order to perfect and maintain the perfection of the
Secured Party's security interests therein and security interest thereon, or
priority (iii) taking all actions required to be consistent with present and
future practices of third-party creditors intending to perfect security
interests in satellites owned by United States persons launched from any
location and (iv) taking all actions reasonably required from time to time to
create, maintain, ensure the priority of, and perfect security interests in
satellites like the EDS Satellite (both before and after launch and while in
orbit and prior to and after any permitted sale) as specified in any United
States, foreign or international law, regulation, convention or treaty relating
to the creation, perfection and/or priority of security interests and security
interests in satellites.

      (e) Insurance. All cash proceeds of Insurance Policies, up to the maximum
amount of the then outstanding Secured Obligations shall be paid to and held by
the Secured Party as cash collateral hereunder in an account in Seller's name
pursuant to a control agreement in customary form, pursuant to which Secured
Party has exclusive control thereof (including, for the avoidance of doubt and
without limitation, the right to make withdrawals in accordance with the terms
of this Agreement without consent of the Seller). The Secured Party agrees that
it will invest any such cash collateral only in Cash Equivalents. Proceeds of
such investments shall be held by the Secured Party as additional collateral
hereunder until it holds cash collateral (or investments thereof) equal to the
amount of the outstanding Secured Obligations, and thereafter the Secured Party
shall promptly pay such excess over to the Seller.

      (f) Other Cash Collateral. Notwithstanding anything herein contained to
the contrary, so long as no Security Event of Default shall have occurred and be
continuing, the Obligors will be permitted without restriction to use any cash
Collateral (other than cash proceeds from the Insurance Policies, which shall be
governed by Section 4.04(e) of this Agreement) and nothing herein shall create
any obligation for an Obligor to transfer such cash Collateral to the Secured
Party.

      SECTION 4.05. TT&C Deliverables. For the purpose of enabling the Secured
Party to exercise rights and remedies under Section 5.01, at such time as the
Secured Party shall be lawfully entitled to exercise such rights and remedies
the Obligors will furnish Buyer with the documentation, data and software
specified in Annex 4 hereto, one (1) set of encryption keys that are compatible
with the EDS spacecraft secure command system and one (1) command encryptor, in
each case which shall conform with the requirements of Exhibit A to the EDS
Contract (collectively, the "Deliverables"),
<PAGE>
subject to all requisite government approvals and compliance with all
governmental procedures, and agree to use their respective commercially
reasonable efforts to assist the Secured Party in obtaining such approvals and
complying with such procedures.

      The Buyer acknowledges that its access to certain of the Collateral will
be subject to U.S. laws ("Restricted Deliverables"), including without
limitation, U.S. export control laws. Accordingly, Buyer agrees that
notwithstanding anything contained herein to the contrary, Buyer shall not take
any action that would constitute a violation of applicable U.S. laws and shall
obtain all such approval and consent as may be necessary for it to obtain access
to the Restricted Deliverables, including without limitation, such approvals and
consents as may be required under U.S. export control laws.

      Notwithstanding anything contained herein to the contrary, Buyer shall
also not take any action relating to the Deliverables that would constitute a
violation of applicable Brazilian laws and regulations or of the ANATEL
Concession Agreement; or (ii) permit early termination or cause forfeiture of
the ANATEL Concession.

                                    ARTICLE V
                           EVENTS OF DEFAULT; REMEDIES

      SECTION 5.01. Security Events of Default. During the period during
which a Security Event of Default shall have occurred and be continuing:

      (a) each Obligor shall, at the request of the Secured Party, assemble the
Collateral owned by it at such place or places, reasonably convenient to both
the Secured Party and such Obligor, designated in its request;

      (b) the Secured Party may make any reasonable compromise or settlement
deemed desirable with respect to any of the Collateral and may extend the time
of payment, arrange for payment in installments, or otherwise modify the terms
of, any of the Collateral;

      (c) the Secured Party shall have all of the rights and remedies with
respect to the Collateral of a secured party under the Uniform Commercial Code
(whether or not said Code is in effect in the jurisdiction where the rights and
remedies are asserted) and such additional rights and remedies to which a
secured party is entitled under the laws in effect in any jurisdiction where any
rights and remedies hereunder may be asserted, including, without limitation,
the right, to the maximum extent permitted by law, to exercise all voting,
consensual and other powers of ownership pertaining to the Collateral as if the
Secured Party were the sole and absolute owner thereof (and each Obligor agrees
to take all such action as may be reasonably necessary to give effect to such
right) and the power of sale and other powers specified in the Conveyance Act
1983 of Bermuda, as varied or amended by this Agreement;

      (d) the Secured Party in its discretion may, in its name or in the name of
the Obligors or otherwise, demand, sue for, collect or receive any money or
property at any time payable or receivable on account of or in exchange for any
of the Collateral, but shall be under no obligation to do so; and

      (e) the Secured Party may, upon 30 days' prior written notice to the
Obligors of the time and place, with respect to the Collateral or any part
thereof that shall then be or shall thereafter come into the possession, custody
or control of the Secured Party or any of their respective agents, sell,
transfer, lease, assign or otherwise dispose of all or any part of such
Collateral, at such place or places as the Secured Party deems best, and for
cash or for credit or for future delivery, at public or private sale, without
demand of performance or notice of intention to effect any such disposition or
of the time or place thereof (except such notice as is required above or by
applicable statute and cannot be waived), and any Secured Party or anyone else
may be the purchaser, transferee, lessee, assignee or recipient. of any or all
of the Collateral so disposed of at any public sale (or, to the extent permitted
by law, at any private sale) and thereafter hold the same absolutely, free from
any claim or right of whatsoever kind, including any right or equity of
redemption (statutory or otherwise), of the Obligors, any such demand, notice
and right or equity being hereby expressly waived and released. The Secured
Party may, without notice or publication, adjourn any public or private sale or
cause the same to be adjourned from time to time by announcement at the time and
place fixed for the sale, and such sale may be made at any time or place to
which the sale may be so adjourned.
<PAGE>
      Notwithstanding the foregoing, the Secured Party agrees that it will not
take, and will not require any Obligor to take, any action pursuant to this
Section 5.01 with respect to any Pledged Stock or other Collateral until such
time as any government approval or consent required in connection therewith,
including, without limitation, that of ANATEL has been granted or obtained and
will not take, and will not require any Obligor to take, any action pursuant to
this Section 5.01 with respect to any of the Deliverables in violation of any
applicable laws or regulations or of the ANATEL Concession Agreement. Following
the occurrence and during the continuance of any Security Event of Default the
Obligors shall at the request of the Secured Party use their reasonable best
efforts to assist the Secured Party in obtaining any governmental approval or
consent, including that of ANATEL, that may be necessary to allow for the
exercise remedies provided herein with respect to the Collateral.

      The proceeds of each collection, sale or other disposition under this
Section, including by virtue of the exercise of the license granted to the
Secured Party in Section 4.04(c), shall be applied in accordance with Section
5.05. Any such sale or other disposition under this Section shall be conducted
in a commercially reasonable manner.

      The Obligors recognize that, by reason of certain prohibitions contained
in the Securities Act of 1933, as amended, and applicable state securities laws,
the Secured Party may be compelled, with respect to any sale of all or any part
of the Collateral, to limit purchasers to those who will agree, among other
things, to acquire the Collateral for their own account, for investment and not
with a view to the distribution or resale thereof The Obligors acknowledge that
any such private sales may be at prices and on terms less favorable to the
Secured Party than those obtainable through a public sale without such
restrictions, and, notwithstanding such circumstances, agree that any such
private sale shall be deemed to have been made in a commercially reasonable
manner and that the Secured Party shall have no obligation to engage in public
sales and no obligation to delay the sale of any Collateral for the period of
time necessary to permit the respective issuer thereof to register it for public
sale.

      SECTION 5.02. Deficiency. If the proceeds of sale, collection or other
realization of or upon the Collateral pursuant to Section 5.01 are insufficient
to cover the costs and expenses of such realization and the payment in full of
the Secured Obligations, SS/L (but not any other Obligor) shall remain liable
for any deficiency.

      SECTION 5.03. Removals, Etc. Except upon at least 30 days' prior written
notice to the Secured Party, each Obligor shall not: (i) maintain the original
or "master" copies of any of its books and records with respect to the
Collateral at any office or maintain its principal place of business at any
place, or (except with respect to Collateral in the possession of the Secured
Party) permit any Collateral to be located anywhere other than at one of the
locations identified in Annex 5 under its name (other than the EDS Satellite in
orbit), or (ii) change its name from the name shown on the signature pages
hereto.

      SECTION 5.04. Private Sale. No Secured Party shall incur any liability as
a result of the sale of the Collateral, or any part thereof, at any private sale
pursuant to Section 5.01(e) conducted in a commercially reasonable manner. Each
Obligor hereby waives any claims against the Secured Party arising by reason of
the fact that the price at which the Collateral may have been sold at such a
private sale was less than the price that might have been obtained at a public
sale or was less than the aggregate amount of the Secured Obligations, even if
the Secured Party accepts the first offer received and does not offer the
Collateral to more than one offeree.

      SECTION 5.05. Application of Proceeds. Except as otherwise herein
expressly provided, the proceeds of any collection, sale or other realization of
all or any part of the Collateral pursuant hereto, and any other cash at the
time held by the Secured Party under this Agreement, shall be applied by the
Secured Party:

      First, to the payment in full of the Secured Obligations; and

      Thereafter, to the payment to the respective Obligor, or their respective
successors or assigns, or as a court of competent jurisdiction may direct, of
any surplus then remaining.


      As used in this Article, "proceeds" of Collateral means cash, securities
and other property realized in respect of, and distributions in kind of,
Collateral, including any thereof received under any reorganization, liquidation
or adjustment of debt of the Obligors or any issuer of or obligor on any of the
Collateral.
<PAGE>
      SECTION 5.06. Attorney-in-Fact. Without limiting any rights or powers
granted by this Agreement to the Secured Party while no Security Event of
Default has occurred and is continuing, upon the occurrence and during the
continuance of any Security Event of Default the Secured Party is hereby
appointed the attorney-in-fact of each Obligor for the purpose of carrying out
the provisions hereof and taking any action and executing any instruments that
the Secured Party may reasonably deem necessary or advisable to accomplish the
purposes hereof, which appointment as attorney-in-fact is irrevocable and
coupled with an interest. Without limiting the generality of the foregoing, so
long as the Secured Party shall be entitled under this Article V to make
collections in respect of the Collateral, the Secured Party shall have the right
and power to receive, endorse and collect all checks made payable to the order
of any Obligor representing any dividend, payment or other distribution in
respect of the Collateral or any part thereof and to give full discharge for the
same.

      SECTION 5.07. Perfection and Priority. Prior to or concurrently with the
execution and delivery of this Agreement, each Obligor shall (i) file such
financing statements and other documents in such offices as the Secured Party
may reasonably request to perfect or ensure the priority of the security
interests granted by Article III, (ii) take any action as the Secured Party may
reasonably request to perfect the pledge of any ownership interests for purposes
of Article 8 of the Uniform Commercial Code and/or (iii) deliver to the Secured
Party all certificates identified in Annex 2, accompanied by undated stock or
transfer powers or share transfer forms duly executed in blank.

      SECTION 5.08. Release of Collateral Termination.

      (a) Upon the earlier of (i) the performance and payment in full of all
Secured Obligations, (ii) prepayment by Seller to Secured Party of an amount
equal to $50 million less the sum of all milestone payments earned by Seller to
date pursuant to the Procurement Agreement, and (iii) the termination of the
Procurement Agreement by the Secured Party pursuant to Article 17 thereof, this
Agreement shall automatically terminate.

      (b) At all times after the amount of cash Collateral (including
investments thereof) held by the Secured Party shall first equal the then
outstanding Secured Obligations, the sole Collateral under this Agreement shall,
subject to Section 5.08(c) below, be such cash Collateral, and the Obligors
shall be relieved from compliance with any and all obligations, representations
and warranties under this Agreement with respect to any other Collateral,
including, without limitation, those set forth in Article IV.

      (c) If at any time the amount of cash Collateral (including investments
thereof) held by the Secured Party shall exceed the then outstanding Secured
Obligations, such excess cash Collateral shall cease to constitute Collateral
and the Obligors shall at all times thereafter be relieved from compliance with
any and all obligations, representations and warranties under this Agreement
with respect to such excess cash Collateral, including, without limitation,
those set forth in Article IV. The Secured Party shall promptly pay to Seller
such excess cash Collateral.

      (d) At any time that any property of the Obligors shall cease to
constitute Collateral under this Agreement (including, for the avoidance of
doubt, upon termination of this Agreement), the Secured Party shall forthwith
cause to be assigned, transferred and delivered, against receipt but without any
recourse, warranty or representation whatsoever (except that the Secured Party
assigns, transfers and delivers free of any Lien created with its consent), any
such property and money received in respect thereof, to or on the order of the
respective Obligor and to be released and canceled all licenses and rights
referred to in Section 4.04(c) that cease to constitute Collateral. The Secured
Party shall also execute and deliver to the respective Obligor upon such release
of property of the Obligors such Uniform Commercial Code termination statements
and such other documentation as shall be reasonably requested by the respective
Obligor to effect the termination and release of the security interest on such
property. Nothing in the foregoing shall be deemed to require a release of
Buyer's security interest in all work-in-progress on the Purchased Satellite,
which shall continue in full force and effect pursuant to the terms of the
Procurement Agreement.

      SECTION 5.09. Further Assurances. Each Obligor agrees that, from time to
time upon the written request of the Secured Party, such Obligor will execute
and deliver such further documents and do such other acts and things as the
Secured Party may reasonably request in order fully to effect the purposes of
this Agreement. Without limiting the foregoing, each Obligor hereby authorizes
the Secured Party to file one or more financing or continuation statements, and
amendments thereto, relative to all or any part of the Collateral without the
signature of such Obligor where permitted by law, provided that copies of any
such statement or amendment thereto shall promptly be delivered to the Company.
Notwithstanding the foregoing, nothing in this Agreement shall require any
Obligor to obtain any "control agreement" relating to accounts prior to the
occurrence and continuance of a Security Event of Default.
<PAGE>
      SECTION 5.10. Standstill. Notwithstanding any provision of this Agreement
to the contrary providing rights to the Secured Party or imposing obligations on
any Obligor which are expressly available only after a Security Event of Default
shall have occurred, the Secured Party shall not exercise any such rights and no
Obligor shall have any such obligation unless (i) the Secured Obligations are
due and unpaid pursuant to the terms of the Procurement Agreement, and (ii) the
Secured Party shall given to the Obligors at least 30 days' prior written notice
of intent to exercise such right or to bind the Obligor to such obligation.

                                   ARTICLE VI
                                  MISCELLANEOUS

      SECTION 6.01. No Waiver. No failure on the part of the Secured Party or
any other- Secured Party to exercise, and no course of dealing with respect to,
and no delay in exercising, any right, power or remedy hereunder shall operate
as a waiver thereof; nor shall any single or partial exercise by the Secured
Party or any other Secured Party of any right, power or remedy hereunder
preclude any other or further exercise thereof or the exercise of any other
right, power or remedy. The remedies herein are cumulative and are not exclusive
of any remedies provided by law.

      SECTION 6.02. Notices. All notices, requests, consents and demands
hereunder shall be in writing and telecopied or delivered to the intended
recipient at (i) in the case of each Obligor, c/o the Seller at the address
specified in the Procurement Agreement; and (ii) in the case of the Secured
Party at the address specified for it in the Procurement Agreement, and shall be
deemed to have been given at the times specified for such types of notices in
the Procurement Agreement.

      SECTION 6.03. Expenses.

      (a) Seller agrees to reimburse the Secured Party for all reasonable costs
      and expenses of the Secured Party (including, without limitation, the
      reasonable fees and expenses of legal counsel) in accordance with the
      final sentence of this paragraph 6.03(a) in connection with (i) any
      Security Event of Default and any enforcement or collection proceeding
      resulting therefrom, including, without limitation, all manner of
      participation in, or other involvement with (w) performance by the Secured
      Party of any obligations of the Obligors in respect of the Collateral that
      the Obligors have failed or refused to perform, (x) bankruptcy,
      insolvency, receivership, foreclosure, winding up or liquidation
      proceedings of any Obligor (other than those in existence on the date
      hereof), or any actual or attempted sale, or any exchange, enforcement,
      collection, compromise or settlement in respect of any of the Collateral,
      and for the care of the Collateral and defending or asserting rights and
      claims of the Secured Party in respect thereof, by litigation or
      otherwise, including expenses of insurance, (y) judicial or regulatory
      proceedings and (z) workout, restructuring or other negotiations or
      proceedings (whether or not the workout, restructuring or transaction
      contemplated thereby is consummated) and (ii) the enforcement of this
      Section. Seller's obligation to reimburse the Secured Party for such
      reasonable costs and expenses under this Section 6.03(a) shall be limited
      as follows: (1) Seller shall reimburse up to the first $300,000 of the
      reasonable costs and expenses of the Secured Party, (2) costs and expenses
      of the Secured Party in excess of $300,000 and less than $800,000 shall be
      for the Secured Party's own account, and (3) Seller shall reimburse the
      reasonable costs and expenses of the Secured Party in excess of $800,000.

      (b) The Seller will pay all filing, registration and recording fees or
      refiling, re-registration and re-recording fees, and all expenses incident
      to the execution and delivery of this Agreement, any agreement
      supplemental hereto and any instruments of further assurance, and all
      federal, state, county and municipal stamp taxes and other taxes, duties,
      imposts, assessments and charges arising out of or in connection with the
      execution and delivery of any Security Document.

      (c) The Seller will pay, before any fine, penalty, interest or cost
      attaches thereto, all taxes, assessments and other governmental or
      non-governmental charges or levies now or hereafter assessed or levied
      against the Collateral or upon the Security interests provided for herein
      as well as pay, or cause to be paid, all claims for labor, materials or
      supplies which, if unpaid, might by law become an Encumbrance thereon, and
      will retain copies of, and, upon request, permit the Secured Party to
      examine, receipts showing payment of any of the foregoing, in each case
      only to the extent that nonpayment is reasonably likely to impair the
      Collateral or the ability of the Obligors to perform their obligations
      under this Agreement.
<PAGE>
      SECTION 6.04. Amendments, Etc. The terms of this Agreement may be waived,
altered or amended only by an instrument in writing duly executed by each
Obligor and the Secured Party. Any such amendment or waiver shall be binding
upon the Secured Party, each other Secured Party and each Obligor.

      SECTION 6.05. Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the respective successors and assigns of each
Obligor and the Secured Party provided, however, that no Obligor shall assign or
transfer its rights hereunder without the prior written consent of the Secured
Party.

      SECTION 6.06. Captions. The caption and section headings used herein are
for convenience of reference only, are not part of this Agreement and shall not
affect the construction of, or be taken into consideration in interpreting, this
Agreement.

      SECTION 6.07. Counterparts. This Agreement may be executed in counterparts
(and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract.

      SECTION 6.08. GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF
PROCESS.

      (a)  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
      GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

      (b) EACH OBLIGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR
      ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE SUPREME
      COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE
      UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY
      APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT
      OF OR RELATING TO THIS AGREEMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY
      JUDGMENT, AND EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND
      UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR
      PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE OR, TO THE
      EXTENT PERMITTED BY LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO
      AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE
      CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE
      JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT
      SHALL AFFECT ANY RIGHT THAT THE SECURED PARTY MAY OTHERWISE HAVE TO BRING
      ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AGAINST ANY OBLIGOR OR
      ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

      (c) EACH OBLIGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE
      FULLEST EXTENT IT MAY LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION WHICH
      IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR
      PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT IN ANY COURT
      REFERRED TO IN PARAGRAPH (B) OF THIS SECTION. EACH OF THE PARTIES HERETO
      HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE
      DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR
      PROCEEDING IN ANY SUCH COURT.

      (d) TO THE EXTENT THAT ANY OBLIGOR MAY BE OR BECOME ENTITLED, IN ANY
      JURISDICTION IN WHICH JUDICIAL PROCEEDINGS MAY AT ANY TIME BE COMMENCED
      WITH RESPECT TO THIS AGREEMENT, TO CLAIM FOR ITSELF OR ITS PROPERTY OR
      REVENUES ANY IMMUNITY FROM SUIT, COURT JURISDICTION, ATTACHMENT PRIOR TO
      JUDGMENT, ATTACHMENT IN AID OF EXECUTION OF A JUDGMENT, EXECUTION OF A
      JUDGMENT OR FROM ANY OTHER LEGAL PROCESS OR REMEDY RELATING TO ITS
      OBLIGATIONS UNDER THIS AGREEMENT AND TO THE EXTENT THAT IN ANY SUCH
      JURISDICTION THERE MAY BE ATTRIBUTED SUCH AN IMMUNITY (WHETHER OR NOT
      CLAIMED), SUCH OBLIGOR HEREBY
<PAGE>
      IRREVOCABLY AGREES NOT TO CLAIM AND HEREBY IRREVOCABLY WAIVES SUCH
      IMMUNITY TO THE FULLEST EXTENT PERMITTED BY THE LAWS OF SUCH JURISDICTION.

      SECTION 6.09. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

      SECTION 6.10. No Third Party Beneficiaries. The agreements of the
parties hereto are solely for the benefit of the Obligors and the Secured
Party, and no other Person shall have any rights hereunder.

      SECTION 6.11. Aunts and Attorneys-in-Fact. The Secured Party may employ
agents and attorneys-in-fact in connection herewith and shall not be responsible
for the negligence or misconduct of any such agents or attorneys-in-fact
selected by it in good faith.

      SECTION 6.12. Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

      SECTION 6.13. Overriding Transactions; Savings. The parties hereby consent
to the transactions listed on Annex 1, but only to the extent that any
transaction subject to such consent would not materially adversely affect the
continued validity, enforceability and perfection of the security interests
provided for herein. In addition, the Secured Party hereby acknowledges and
agrees that Skynet/Brazil does not purport to grant any security interest in the
EDS Satellite hereunder, but merely confirms that all right, title and interest
it may acquire therein is or will be acquired subject to any preexisting
security interest created by Seller pursuant to the terms hereof prior to the
EDS Satellite being transferred to SkynetBrazil.

      SECTION 6.14. Conflicting Provisions. In the event of conflict or
inconsistency between the provisions of this Agreement and the provisions of the
Quota Pledge Agreement, the latter shall prevail.
