REVISED

                           DTH SYSTEM IN LATIN AMERICA
                           MEMORANDUM OF UNDERSTANDING

                  This Revised Memorandum of Understanding ("Revised MOU") dated
as of September 20, 1996 is made in respect of that certain DTH System in Latin
America Memorandum of Understanding ("Original MOU") dated as of March 27, 1995,
between PanAmSat Corporation, a Delaware corporation ("PanAmSat"), and Grupo
Televisa, S.A., a Mexican corporation ("Televisa"). Unless otherwise
specifically set forth herein, capitalized terms used in this Revised MOU which
are defined in the Original MOU are used as defined in the Original MOU.

                  A. Televisa has entered, or is about to enter, into a
Memorandum of Understanding (the "North America MOU") with The News Corporation
Limited or its designee ("News Corp.") and Telecommunications International,
Inc. or its designee ("TCII") relating to the establishment and operation of a
DTH business (the ("North America Platform") in the Territory, as therein
defined. It is anticipated that the North America Platform will be divided
between the North America Platform/Mexico and the North America Platform/U.S.
(which together with any divided Multi-Country Platforms described below are
sometimes referred to herein as "sub-Platforms"), as more specifically defined
and described in the North America MOU. A copy of the North America MOU is
attached to this Revised MOU as Exhibit A.

                  B. Televisa has entered, or is about to enter, into a
Memorandum of Understanding (the "Multi-Country MOU") with News Corp., TCII and
Globo Participacoes Ltda. ("Globo") relating to the establishment and operation
of a DTH business in those countries in Latin America which are included in the
Multi-Country Platform, as defined in the Multi-Country MOU. It is anticipated
that Argentina and Chile will be divided from the Multi-Country Platform into a
separate sub-Platform or sub-Platforms as described in the Multi-Country MOU. A
copy of the Multi-Country MOU is attached to this Revised MOU as Exhibit B. The
North America MOU and the Multi-Country MOU are collectively called the "News
MOUs" and Televisa, News Corp., Globo and TCII and their respective affiliates
in their capacity as owners of the North America Platform and the Multi-Country
Platform are collectively called the "Platform Partners" and are sometimes
individually called a "Platform Partner."

                  C. News Corp. and Globo have entered, or are about to enter,
into a Memorandum of Understanding (the "Brazil MOU") relating to the
establishment of a DTH business in Brazil. Televisa shall have no participation
in the ownership or operation (other than as described in the News MOUs) in the
DTH business in Brazil.
<PAGE>
                  D. In order to facilitate the arrangements under the News
MOUs, Televisa and PanAmSat desire to modify their agreements in the Original
MOU and enter into new agreements as provided herein, subject to the terms and
conditions of this Revised MOU.

                  In consideration of the foregoing premises and the agreements,
covenants and conditions set forth below, the parties agree as follows:

                  1. PanAmSat Ownership in North America Platform and
Multi-Country Platform; Tag Along Rights.

                  1.1 PanAmSat Right to Purchase. PanAmSat shall have the right
to purchase from Televisa non-voting equity interests of 15% in the North
America Platform/Mexico, 12% in the North America Platform/U.S., 14% in the
Multi-Country Platform (excluding Argentina and Chile) and 10% in the
Multi-Country Platform for Argentina and Chile, all of such equity interests
being determined on a fully-diluted basis and all being subject to dilution pro
rata with Televisa in the event that additional partners other than the Platform
Partners are admitted to the Platforms (the "PanAmSat Interests"), which right
shall be exercised in full and not in part on or before the tenth anniversary of
the date of this Revised MOU. Until and unless PanAmSat exercises its right to
purchase the PanAmSat Interests, such interests shall be owned and held by
Televisa or one or more wholly-owned Platform SRLs, as defined below. All voting
rights with respect to the PanAmSat Interests will be exercised by Televisa at
all times. The purchase price for the PanAmSat Interests shall be equal to the
share of Televisa's capital contributions to the respective Platforms allocable
to the PanAmSat Interests, to the extent such contributions have not been
recovered through distributions to Televisa by the Platforms, (a) plus interest
on the outstanding balance thereof from time to time (calculated from the date
of each contribution or of each expenditure made and credited by the Platform(s)
to the capital commitment of Televisa) at the rate of 9.75% per annum, (b) plus
any taxes incurred and/or reductions in tax benefits suffered by Televisa
attributable to such transfer (other than income tax on the interest component
of the purchase price), and (c) minus interest on outstanding balance of the
Reimbursable Expenses, as defined below, from time to time (calculated from the
date of each such Reimbursable Expense) at the rate of 9.75% per annum. Televisa
acknowledges that in no event may PanAmSat exercise its right to purchase the
PanAmSat Interests prior to the date (the "Indenture Covenant Date") on which
PanAmSat was required to purchase its ownership interest in Holdco under the
first sentence of such Section 2.4.1 of the Original MOU. The parties shall
execute a definitive option agreement granting the right to purchase the
PanAmSat Interests as provided in this Section 1.1 as soon as practicable
following the execution of this Revised MOU.
<PAGE>
                  1.1.1 Subject to the terms of Section 1.1.2 below, PanAmSat
         agrees to take the PanAmSat Interests through one or more special
         purpose Mexican sociedades de responsabilidad limitada (the "Platform
         SRLs") where (x) its taking such interests directly in the Platforms
         (i) would act to prevent Televisa from achieving consolidation
         treatment for Mexican tax or accounting purposes with respect to its
         ownership in the Platform or (ii) is the only legally effective
         mechanism under which Televisa would have the perpetual and exclusive
         ability and right to exercise the voting rights associated with
         PanAmSat's interest in the Platform and (y) subject to Section 1.1.2
         below, PanAmSat is reasonably satisfied that taking its ownership
         through the Platform SRLs as opposed to taking a direct interest in the
         Platforms would not result in any negative tax effect upon PanAmSat.

                  1.1.2 It is the intention of the parties that where Section
         1.1.1 would call for the use of one or more Platform SRLs by Televisa
         and PanAmSat, the PanAmSat Interests in each Platform (or each
         sub-Platform as the case may be) will be held in a separate Platform
         SRL, provided, however that upon Televisa's request, the PanAmSat
         Interests in more than one Platform or sub-Platform may be held in one
         Platform SRL if (i) Televisa's reasonable tax or accounting
         circumstances require same and (ii) PanAmSat will not suffer any
         adverse effect as a result of same as to which adverse effect PanAmSat
         has not been adequately indemnified and held harmless by Televisa. In
         the case where holding the PanAmSat Interests, or any of them, in a
         Platform SRL would not satisfy the condition set forth in clause (y) of
         Section 1.1.1, Televisa may (a) deliver the affected PanAmSat Interest
         to PanAmSat in the Platform directly, (b) deliver the affected PanAmSat
         Interest to PanAmSat in another form of entity reasonably acceptable to
         PanAmSat which otherwise satisfies the conditions of Section 1.1.1 and
         Section 1.2 below, or (c) upon Televisa's agreement to indemnify
         PanAmSat and hold it harmless from such negative tax effect and to put
         PanAmSat in the same tax position in which it would have been had it
         taken such PanAmSat Interest directly, which agreement shall be in form
         and substance reasonably acceptable to PanAmSat, require PanAmSat to
         accept the PanAmSat Interest in a Platform SRL.

                  1.2 Minority Equity Holder Rights. Televisa covenants and
agrees with PanAmSat that: (a) DTH activities of the Platform Partners conducted
within the respective territories covered by the North America Platform and the
Multi-Country Platform will be conducted exclusively in such Platforms and
through no other corporation, partnership or other form of business organization
until the Platform is dissolved and no follow-on DTH business is thereafter
operated by two or more of the Platform Partners one of which is Televisa
(unless PanAmSat is given the opportunity to invest therein in the same
<PAGE>
proportion to Televisa's equity and in the same manner as in the dissolved
Platform) or, as to any Platform Partner or Platform Partners, the withdrawal of
such Platform Partner or Platform Partners from a Platform with the consent of
the other Platform Partners, (b) if Televisa owns its interests in the North
America Platform and/or the Multi-Country Platform in a Platform SRL in which
PanAmSat has taken an ownership interest as contemplated in Section 1.1 above,
Televisa's ownership in such Platform(s) will be, directly and indirectly,
exclusively through such Platform SRL(s) and such Platform SRL(s) shall be
special purpose entities with Televisa (and/or its wholly-owned affiliates) and
PanAmSat as the sole equity owners and with no business, assets, liabilities,
commitments or understandings other than their stock interest in such
Platform(s) and the liabilities, commitments and understandings related thereto
as described in the News MOUs, (c) all transactions (other than those
transactions which are specifically described in the News MOUs) directly or
indirectly between the Platform Partners and the Platforms will be at arm's
length on commercially reasonable terms, or PanAmSat will be made financially
whole by Televisa, (d) if PanAmSat is holding its ownership interest in a
Platform through a Platform SRL and the Platform's securities become publicly
traded, at PanAmSat's request from time to time, Televisa will cause PanAmSat's
ownership interest in the Platform SRL, or such part thereof which PanAmSat may
desire to sell in a market transaction or transactions, to be converted to a
direct interest in the Platform in the securities which are publicly traded in
order to allow PanAmSat to effect such a transaction or transactions, which
transactions shall be subject on a pro rata basis with Televisa to any transfer
limitations imposed by the Platform on the Platform Partners, (e) Televisa will
furnish PanAmSat, or an independent third party selected by PanAmSat and
reasonably acceptable to Televisa and the other Platform Partners, with
reasonable access to the books and records of the Platforms (subject to normal
and customary confidentiality provisions) to allow PanAmSat to ascertain whether
the foregoing covenants have been complied with. To the extent the covenants set
forth above contemplate action or inaction on the part of the Platform Partners
other than Televisa, Televisa will use all reasonable efforts to obtain such
action or inaction. Moreover, Televisa, at PanAmSat's request, will enforce such
covenants at the Platform level or at its election may in lieu of such
enforcement indemnify and hold PanAmSat harmless from any loss, cost or damage
which may result by reason of Televisa's failure to enforce such covenants. In
no event will Televisa consent to any breach or non-performance of such
covenants by the Platform Partners unless the Platforms or PanAmSat receive
indemnification reasonably acceptable to them. In the event Televisa is required
by PanAmSat to enforce such covenants where Televisa has not consented to the
breach or non-performance thereof by the other Platform Partners, PanAmSat will
pay a share of the costs of such enforcement which share will be pro rata with
Televisa if Televisa is enforcing such covenants for PanAmSat and for its own
account (or Televisa otherwise obtains the benefit of such enforcement) or which
<PAGE>
share will be 100% if Televisa is enforcing such covenants solely for PanAmSat
and does not obtain any of the benefit therefrom. Notwithstanding the foregoing,
Televisa's sole obligation shall be to act or refrain from acting in accordance
with this Section and Televisa shall have no liability to PanAmSat hereunder by
reason of the acts or omissions of the third parties including the other
Platform Partners. Anything in this Section 1.2 to the contrary notwithstanding,
if the rights granted to PanAmSat herein are broader than the rights granted to
TCII with respect to the specific matters described in clauses (a) and (c)
through (e), then PanAmSat shall accept the same rights as are accorded to TCII
with respect to such matters. The rights described in this Section 1.2 shall be
more specifically set forth in long-form documentation which shall be negotiated
and executed as soon as practicable following the execution of this Revised MOU.

                  1.3 Tag Along Right; Bring Along Right. Televisa grants to
PanAmSat the right (the "Tag Along Right") to participate, on a pro rata basis
in any sale or other disposition by Televisa which is effected either directly
or through a Platform SRL as described above, as the case may be, of any
ownership interest held by it in the North America Platform or the Multi-Country
Platform (whether at the Platform level or the Platform SRL level) on the same
terms and conditions as such sale or disposition is made by Televisa or other
person or entity. In the event such a transaction occurs prior to the Indenture
Covenant Date, PanAmSat shall be entitled to receive, on exercise of the Tag
Along Right, an amount in respect of the portion of the PanAmSat Interests which
would otherwise have been includable in such transaction equal to the purchase
price or other consideration which would have been received by PanAmSat less the
purchase price which PanAmSat would have been required to pay under Section 1.1
above upon the purchase of such portion calculated as of the date the
transaction is consummated. The Tag Along Right shall be exercised not later
than twenty days following receipt by PanAmSat of written notice of all material
terms of the proposed transaction. Televisa shall have a comparable "bring
along" right to require PanAmSat to sell the PanAmSat Interest in any of the
Platforms either directly or through a Platform SRL as described above, as the
case may be, if Televisa wishes to sell all of its interest in a Platform in a
bona fide arm's length transaction with a third party for fair market value. The
rights described in this Section 1.3 shall be more specifically set forth in
long-form documentation which shall be negotiated and executed as soon as
practicable following the execution of this Revised MOU.

                  1.4 PanAmSat Right to Sell Interest. PanAmSat shall have the
right to sell its interest in the Platforms (or the applicable Platform SRL(s),
as the case may be) to the extent, if any, such right is provided in the News
MOUs, subject to a right of first refusal in Televisa and/or News Corp., Globo
and TCII.
<PAGE>
                  1.5 Televisa Right to Cash Out Option Under Certain
Circumstances. The parties acknowledge that Section 6 of the Schedule of General
Terms to each of the News MOUs (the "Section 6 Provisions") provides that any
transferee of Televisa shall be subject to any obligations of Televisa with
respect to exclusivity and non-competition under the News MOUs. Except as
contemplated hereby, during the term of this Agreement (except for a Permitted
Violation), neither PanAmSat nor any of its subsidiaries shall own any equity
interest in a predominantly Spanish-language DTH service in the Americas. Except
for circumstances constituting a Permitted Violation, as defined below, PanAmSat
shall not be permitted to exercise its right to purchase the PanAmSat Interests
if such exercise would cause Televisa to be in violation of the Section 6
Provisions and shall have no recourse or remedy as a result thereof. In the
event that at the time of the exercise of PanAmSat's right to purchase the
PanAmSat Interests, PanAmSat or its affiliates would cause Televisa to be in
violation of the Section 6 Provisions by reason of a Permitted Violation,
Televisa shall have the right, in lieu of delivery of the PanAmSat Interests, to
pay to PanAmSat an amount equal to the net fair market value of the PanAmSat
Interests. For purposes of this paragraph: a "Permitted Violation" will be a
violation of the Section 6 Provisions which occurs (or would occur upon the
exercise of PanAmSat's right to purchase the PanAmSat Interests) by reason of
any circumstance or characteristic of any person, firm, corporation or other
entity which acquires an interest in PanAmSat by stock purchase, asset purchase,
merger, consolidation or otherwise (an "acquisition"), which circumstance or
characteristic occurs or exists prior to the acquisition; and the "net fair
market value" of the PanAmSat Interests shall be the fair market value,
determined in a process reasonably acceptable to both parties which process will
take to account the minority position and the liquidity of the PanAmSat
Interests, of the PanAmSat Interests less the purchase price required to be paid
at the time of the exercise of the purchase right.

                  2. Reimbursement of PanAmSat Expenses; Indemnification.

                  2.1 Reimbursement of Expenses. Televisa acknowledges that
PanAmSat has incurred out-of-pocket expenses in the performance of its duties
under the Original MOU which expenses shall not be required to be incurred by
PanAmSat under this Revised MOU, including, but not necessarily limited to the
purchase of compression and related equipment from National Transcommunications
Limited and the purchase of other equipment for provision of DTH technical
services; the making of a deposit to Pace Micro Technology Ltd. in connection
with a seed order for 50,000 integrated receiver/decoders ("IRDs"); travel and
consulting expenses in the performance of the services under Sections 3.1.1 and
3.1.2 of the Original MOU; and construction of improvements to house equipment
for the provision of DTH technical services at PanAmSat's Atlanta, Georgia and
Homestead, Florida facilities, the total amount of which is $18,877,652.33 as
shown in the itemized schedule attached to this Revised MOU as Exhibit C (the
<PAGE>
"Reimbursable Expenses"), plus any applicable sales tax with respect to
equipment which will be used in any state where such tax is applicable and
PanAmSat is liable for or is responsible for the collection of same. Promptly
upon the execution of this Revised MOU, Televisa shall reimburse PanAmSat for
all such expenses, or shall cause the Platforms or the Platform Partners to
reimburse PanAmSat for all such expenses, it being understood that such
obligation shall be subject to PanAmSat's undertaking to attempt mitigation as
provided below. At Televisa's request, PanAmSat will invoice the Platform
Partners for the Reimbursable Expenses in such proportions as Televisa directs,
provided that if PanAmSat has not been paid by a Platform Partner within 30 days
of the date of this Revised MOU, Televisa will pay PanAmSat and PanAmSat will
assign such invoice to Televisa. PanAmSat shall hold all equipment for which it
is paid hereunder for the account of Televisa, and Televisa shall collect such
equipment (to the extent it will not be used by PanAmSat in the provision of
technical services to the Platforms under separate agreement) not later than
forty-five days following the execution of this Revised MOU. Anything in the
foregoing to the contrary notwithstanding, at the request of Televisa, PanAmSat
agrees to use reasonable efforts to mitigate the costs to be reimbursed under
this Section 2 (either through resale, use of the equipment in PanAmSat's
business (to be determined in PanAmSat's sole discretion) or return to the
manufacturer for credit), where mitigation is reasonably appropriate and
practicable, and any sums received by PanAmSat from such mitigation attempts (or
the cost of any equipment retained by PanAmSat and used in its business) shall
be promptly turned over to Televisa or to the Platforms or Platform Partners in
the same proportions as they paid the Reimbursable Expenses. In the case where
PanAmSat retains equipment for use in its business, the calculation of the price
to be paid upon the purchase of the PanAmSat Interests under the formula set
forth in Section 1.1 shall not include a credit for interest on the equipment
which was so retained. The parties acknowledge that the Platform Partners (or
some of them) are currently negotiating with PanAmSat to use PanAmSat's teleport
in Homestead, Florida for services related to the Platforms, and in connection
therewith may make a payment in respect of the expenses set forth in Exhibit C
to this Revised MOU (the "DTH Teleport Arrangement"). In the event a payment is
made in respect of the expenses set forth in Exhibit C under the DTH Teleport
Arrangement as provided above, Televisa will be given a credit against its
obligation hereunder equal to the amount of such payment. All equipment to be
delivered by PanAmSat to Televisa and/or the Platforms or Platform Partners
under this Section 2 shall be delivered without representation or warranty,
except that PanAmSat shall assign its rights to representations and warranties
from the vendor to the extent that same are assignable by PanAmSat.

                  2.2 Indemnification Against Certain Liabilities. Televisa
acknowledges that PanAmSat has undertaken certain obligations and incurred
contractual liabilities in the performance of its obligations under Sections
3.1.1 and 3.1.2 of the Original MOU including, but not necessarily limited to,
<PAGE>
the execution of (a) a long-term agreement with National Transcommunications
Limited for compression and related equipment and (b) a memorandum of
understanding for the purchase of IRDs with Pace Micro Technology Ltd. (the
agreements described in clauses (a) and (b) being collectively called the
"Indemnified Agreements"), all of which agreements were executed with the
knowledge and consent of Televisa. Televisa hereby indemnifies PanAmSat and
agrees to hold PanAmSat harmless from and against any and all losses, costs,
expenses or liabilities which may be incurred by PanAmSat as a result of any
claim made against PanAmSat under or by reason of the Indemnified Agreements
(including reasonable attorneys' fees and costs in defending any such claim or
in asserting PanAmSat's rights under this indemnification). PanAmSat shall give
prompt notice to Televisa of any such claim (provided that failure to give such
notice shall not affect Televisa's indemnification herein except to the extent
of any actual damage or prejudice suffered by Televisa as a result thereof),
Televisa shall have the right to defend the same exclusively (unless Televisa
fails to defend same in a timely manner in which event PanAmSat shall have the
right to assume the defense at Televisa's expense upon written notice to
Televisa), and PanAmSat shall not settle or compromise any such claim without
the written consent of Televisa (except that if PanAmSat has assumed the defense
of the claim under the immediately preceding phrase, PanAmSat shall have the
right to settle or compromise such claim at Televisa's cost). At the request of
Televisa, PanAmSat shall cooperate with and provide assistance to Televisa in
(a) obtaining for the Platforms the benefits of any or all of the Indemnified
Agreements to the extent of PanAmSat's benefits thereunder, and (b) compromising
or settling any claims in respect of the Indemnified Agreements.

                  3. Binding Effect; Termination of Original MOU. This Revised
MOU is a binding agreement between the parties, and may be amended or modified
only by a written instrument executed by the parties. By executing this Revised
MOU, PanAmSat consents to the execution by Televisa of the News MOUs and the
consummation of the transactions contemplated therein, subject to performance of
this Revised MOU. Upon the execution of this Revised MOU, the Original MOU shall
be deemed terminated and superseded and all rights and obligations of the
parties thereunder shall be terminated and of no further force or effect. While
this Revised MOU looks to the formation of definitive agreements, the failure of
the parties to execute such definitive agreements shall have no effect upon the
obligations of the parties hereunder and the terms and conditions of this
Revised MOU shall remain binding upon the parties. This Revised MOU and the
exhibits and schedules attached hereto constitute the entire understandings and
agreements of the parties with respect to the matters described herein and all
prior agreements and understandings, whether written or verbal related thereto,
other than an indemnification agreement between Televisa and PanAmSat dated
January 22, 1996 relating to certain agreements between PanAmSat and Irdeto,
B.V. which indemnification agreement shall survive this Revised MOU and shall
not be extinguished, are merged herein and superseded hereby.
<PAGE>
                  4. No Third Party Beneficiaries. Nothing contained in this
Revised MOU is intended to confer on any person or entity (including News, Globo
and/or TCII), other than the parties hereto, any rights, remedies or
obligations.

                  5. Governing Law. This Revised MOU will be governed by and
construed in accordance with the laws of the State of New York, without giving
effect to principles of conflicts of laws.

                  6. Publicity. The terms of this Revised MOU and the
transactions contemplated herein shall not be disclosed or announced by the
parties without prior written notice from the disclosing party to the other
party received by the other party at least one business day prior to the
announcement to the extent practicable. The parties acknowledge that it is in
the best interests of both parties that any announcement of the News MOUs and of
this Revised MOU be coordinated. Copies of all news releases pertaining to this
Revised MOU, the News MOUs or the transactions contemplated herein or therein
made by either party shall be sent to the other party at least one hour prior to
release to the extent practicable.

                  7. Counterparts. This Revised MOU may be executed in one or
more counterparts each of which shall constitute an original agreement.

                  IN WITNESS WHEREOF, the parties have caused this Revised MOU
to be duly executed as of the day and year first above written.
