Dear Fellow Stockholder:
 
  You are cordially invited to attend the Special Meeting of Stockholders (the
"Special Meeting") of PanAmSat Corporation ("PanAmSat"), which will be held on
Thursday, May 8, 1997 at 11:00 a.m. local time at the Equinox Hotel, Historic
Route 7A, Manchester Village, Vermont.
 
  At the Special Meeting you will be asked to consider and vote upon a
proposal to approve and adopt an Agreement and Plan of Reorganization dated as
of September 20, 1996, as amended on April 4, 1997 (the "Reorganization
Agreement"), and an Agreement and Plan of Merger dated as of April 4, 1997
(the "Merger Agreement") that provide for the combination of PanAmSat and the
existing commercial satellite business of Hughes Communications, Inc. and
certain of its subsidiaries (the "Galaxy Business").
 
  Upon completion of the transactions contemplated by the Reorganization
Agreement, the Merger Agreement and various ancillary agreements (the
"Transaction"):
 
  . PanAmSat will become a wholly owned subsidiary of a newly formed holding
    company that will be known as "PanAmSat Corporation" ("New PanAmSat"),
    which will also own and operate the Galaxy Business;
 
  . each issued and outstanding share of Class A Common Stock and Common
    Stock will be converted into, at the election of each holder, either (a)
    the right to receive an amount in cash equal to $15, plus interest under
    certain circumstances, plus one half ( 1/2) share of Common Stock of New
    PanAmSat ("New PanAmSat Common Stock"), (b) the right to receive (subject
    to proration, as applicable) one share of New PanAmSat Common Stock or
    (c) the right to receive (subject to proration, as applicable) an amount
    in cash equal to $30, plus interest under certain circumstances;
 
  . New PanAmSat will acquire all of the capital stock of an entity that
    indirectly owns all of the issued and outstanding shares of Class B
    Common Stock in exchange for consideration at the election of such
    entity's owner that is equal in amount and form (subject to proration, as
    applicable), per share of Class B Common Stock indirectly owned by such
    entity, to the consideration payable on account of each share of Class A
    Common Stock and Common Stock in the Transaction; and
 
  . Hughes Communications, Inc. and certain of its subsidiaries will receive
    an aggregate of 106,622,807 shares of New PanAmSat Common Stock, which
    will represent approximately 71.5% of the outstanding shares of New
    PanAmSat Common Stock after the Transaction assuming that New PanAmSat
    pays the direct and indirect stockholders of PanAmSat half stock and half
    cash as consideration in the Transaction.
 
  At the Special Meeting you will also be asked to consider and vote upon a
proposal to approve and adopt an amendment (the "Charter Amendment") to
PanAmSat's Amended and Restated Certificate of Incorporation. The Charter
Amendment would (i) change the name of PanAmSat to "PanAmSat International
Systems, Inc.," (ii) clarify that the shares of Class A Common Stock and Class
B Common Stock will not lose their status as such as a result of the
Transaction and (iii) clarify that certain restrictions in PanAmSat's
Certificate of Incorporation regarding the consideration that must be received
in a merger, consolidation or business combination will not apply to the
Transaction.
 
  Detailed descriptions of the Reorganization Agreement, the Merger Agreement
and the Charter Amendment are set forth in the accompanying Proxy
Statement/Prospectus, which you should read carefully.
 
  PANAMSAT'S BOARD OF DIRECTORS HAS DETERMINED THAT THE TRANSACTION IS FAIR TO
AND IN THE BEST INTERESTS OF PANAMSAT AND ITS STOCKHOLDERS. PANAMSAT'S BOARD
OF DIRECTORS HAS ALSO DETERMINED THAT THE CHARTER
<PAGE>
 
AMENDMENT IS ADVISABLE AND IN THE BEST INTERESTS OF PANAMSAT AND ITS
STOCKHOLDERS. PANAMSAT'S BOARD OF DIRECTORS HAS APPROVED THE REORGANIZATION
AGREEMENT, THE MERGER AGREEMENT AND THE CHARTER AMENDMENT AND RECOMMENDS A
VOTE "FOR" APPROVAL OF THE REORGANIZATION AGREEMENT AND THE MERGER AGREEMENT
AND RECOMMENDS A VOTE "FOR" APPROVAL OF THE CHARTER AMENDMENT.
 
  The affirmative vote of (i) the holders of a majority of the votes of the
outstanding shares of Class A Common Stock and Common Stock, voting together
as a single class, and the holders of a majority of the votes of the
outstanding shares of Class B Common Stock and Common Stock, voting together
as a single class, as well as (ii) the holders of a majority of the votes of
the outstanding shares of each of the Class A Common Stock and the Class B
Common Stock (as long as the outstanding shares of Class A Common Stock and/or
Class B Common Stock represent at least 5% of the total outstanding shares of
Class A Common Stock, Class B Common Stock and Common Stock), is necessary to
approve the Reorganization Agreement, the Merger Agreement and the Charter
Amendment. In addition, the affirmative vote of the holders of the majority of
votes of the outstanding shares of Class A Common Stock, Class B Common Stock
and Common Stock, each voting as a separate class, is necessary to approve the
Charter Amendment. Pursuant to an agreement executed in connection with the
Reorganization Agreement, the beneficial owners of all of the issued and
outstanding shares of Class A Common Stock and Class B Common Stock have
agreed to vote all of their shares of stock of PanAmSat to approve the
Reorganization Agreement and the Merger Agreement and to take any actions
required in furtherance thereof. In connection therewith, immediately before
the record date for the Special Meeting, the holders of Class A Common Stock
voluntarily converted the number of shares of Class A Common Stock necessary
to constitute a majority of the outstanding shares of Common Stock from Class
A Common Stock into Common Stock (such shares of Common Stock, the "Converted
Shares"). On the record date for the Special Meeting, the beneficial owners of
all of the outstanding shares of Class A Common Stock, Class B Common Stock
and the Converted Shares held the voting power required to approve the
Reorganization Agreement, the Merger Agreement and the Charter Amendment.
Accordingly, approval thereof by the PanAmSat stockholders is assured.
 
  Whether or not you plan to attend the Special Meeting, please complete, sign
and date the enclosed proxy card and return it promptly in the enclosed

and exchange of your shares are being mailed to you.

                               ----------------
 
TO THE STOCKHOLDERS OF PANAMSAT CORPORATION:
 
  Notice Is Hereby Given that a Special Meeting of Stockholders (the "Special
Meeting") of PanAmSat Corporation ("PanAmSat") will be held on Thursday, May
8, 1997 at 11:00 a.m. local time at the Equinox Hotel, Historic Route 7A,
Manchester Village, Vermont for the following purposes:
 
    1. To consider and vote upon a proposal to approve and adopt an Agreement
  and Plan of Reorganization dated September 20, 1996, as amended on April 4,
  1997 (the "Reorganization Agreement"), among Hughes Communications, Inc., a
  California corporation ("HCI"), Hughes Communications Galaxy, Inc., a
  California corporation ("HCG"), Hughes Communications Satellite Services,
  Inc., a California corporation, Hughes Communications Services, Inc., a
  California corporation, Hughes Communications Carrier Services, Inc., a
  California corporation, Hughes Communications Japan, Inc., a California
  corporation, Magellan International, Inc., a Delaware corporation ("New
  PanAmSat"), and PanAmSat, and an Agreement and Plan of Merger dated as of
  April 4, 1997 (the "Merger Agreement") by and among PanAmSat, PAS Merger
  Corp., a Delaware corporation and newly formed subsidiary of New PanAmSat,
  and New PanAmSat.
 
    2. To consider and vote upon a proposal to approve and adopt an amendment
  (the "Charter Amendment") to PanAmSat's Amended and Restated Certificate of
  Incorporation. The Charter Amendment would (i) change the name of PanAmSat
  to "PanAmSat International Systems, Inc.," (ii) clarify that the shares of
  Class A Common Stock, par value $.01 per share, of PanAmSat (the "PAS Class
  A Common Stock") and the shares of Class B Common Stock, par value $.01 per
  share, of PanAmSat (the "PAS Class B Common Stock") will not convert into
  shares of Common Stock, par value $.01 per share, of PanAmSat (the "PAS
  Ordinary Common Stock," and together with the PAS Class A Common Stock and
  PAS Class B Common Stock, the "PAS Common Stock") in connection with the
  Reorganization Agreement, the Univisa Contribution Agreement (as defined
  below) and the transactions contemplated thereby and (iii) clarify that the
  provisions in PanAmSat's Amended and Restated Certificate of Incorporation
  regarding the consideration that must be received in a merger,
  consolidation or business combination will not apply to the transactions
  contemplated by the Reorganization Agreement, the Merger Agreement and the
  Univisa Contribution Agreement (as defined below).
 
    3. To transact such other matters relating to the conduct of the Special
  Meeting or any adjournments or postponements thereof.
 
  See pages 12 and 13 of the Proxy Statement/Prospectus for charts depicting
the existing corporate structure of the entities that will engage in the
transactions described above, the structure of such transactions and the
corporate structure that will be achieved if such transactions are approved
and consummated.
 
  The Reorganization Agreement and the Merger Agreement contemplate, among
other things, that PAS Merger Corp. will be merged with and into PanAmSat (the
"Merger") and the existing commercial satellite business of HCI and certain of
its subsidiaries (the "Galaxy Business") will be contributed to New PanAmSat,
with the result that: (a) PanAmSat will become a wholly owned subsidiary of
New PanAmSat, (b) each issued and outstanding share of PAS Class A Common
Stock and PAS Ordinary Common Stock will be converted,
<PAGE>
 
at the election of each holder, into either (i) the right to receive an amount
in cash equal to $15, plus one half ( 1/2) share of Common Stock, par value
$.01 per share, of New PanAmSat (the "New PAS Common Stock"), (ii) the right
to receive (subject to proration, as applicable) one share of New PAS Common
Stock or (iii) the right to receive (subject to proration, as applicable) an
amount in cash equal to $30 (collectively, the "Merger Consideration"), (c)
New PanAmSat will own and operate the Galaxy Business and (d) HCI and certain
of its subsidiaries will receive an aggregate of 106,622,807 shares of New PAS
Common Stock.
 
  Assuming that New PanAmSat pays half stock and half cash as consideration in
the Merger and the Univisa Contribution (as defined below), the shares of New
PAS Common Stock received by HCI and certain of its subsidiaries will
represent approximately 71.5% of the outstanding shares of New PAS Common
Stock after the Merger. The Reorganization Agreement and the Merger Agreement
provide that the maximum aggregate cash consideration to be paid in connection
with the Merger and the Univisa Contribution will be equal to $15 multiplied
by the number of shares of PAS Common Stock outstanding at the time of the
Merger. In addition, if the closing of the Merger has not occurred on or prior
to September 20, 1997, the cash portion of the consideration payable in the
Merger and the Univisa Contribution will be increased at a rate equal to 9%
per annum from September 20, 1997, to the date of the closing of the Merger.
Finally, New PanAmSat may limit the aggregate number of shares of New PAS
Common Stock that may be issued in the Merger and the Univisa Contribution to
as few as one half ( 1/2) of the number of shares of PAS Common Stock
outstanding at the time of the Merger.
 
  An election to receive all cash in connection with the Reorganization may
result in the receipt of either all cash or, in the event that the aggregate
amount of all elections to receive cash exceeds $15 multiplied by the number
of shares of PAS Common Stock outstanding at the time of the Reorganization, a
combination of cash and shares of New PAS Common Stock. For example, in the
event that all cash is elected by all direct and indirect holders of PAS
Common Stock, each such holder will receive $15 in cash plus one half ( 1/2)
share of New PAS Common Stock on account of each share of PAS Common Stock
held directly or indirectly by such holder.
 
  An election to receive all stock in connection with the Reorganization may
result in the receipt of either all stock or, in the event that (i) the direct
and indirect holders of more than one half ( 1/2) of the number of shares of
PAS Common Stock outstanding at the time of the Reorganization elect to
receive stock on account of such shares and (ii) New PanAmSat exercises its
option to limit the number of additional shares of New PAS Common Stock to be
issued, a combination of cash and shares of New PAS Common Stock. For example,
in the event that all stock is elected by all direct and indirect holders of
PAS Common Stock and New PanAmSat exercises its option to limit the number of
additional shares of New PAS Common Stock to be issued, each such holder will
receive one half ( 1/2) share of New PAS Common Stock plus $15 in cash on
account of each share of PAS Common Stock held directly or indirectly by such
holder. An election to receive $15 in cash and one half ( 1/2) share of New
PAS Common Stock on account of each share of PAS Common Stock will not be
affected by the proration procedures.
 
  The impact of the elections on New PanAmSat will depend upon whether such
elections direct New PanAmSat to issue more stock or pay more cash. If more
stock is issued, less debt will be incurred by New PanAmSat, making it less
highly leveraged. If more cash is paid (up to the proration limits), New
PanAmSat will incur more indebtedness as a result of such payments.
 
  Immediately prior to the Merger, in a separate but related transaction (the
"Univisa Contribution"), pursuant to the Stock Contribution and Exchange
Agreement dated as of September 20, 1996 (the "Univisa Contribution
Agreement") among Grupo Televisa, S.A., a Mexican corporation ("Televisa"),
Satellite Company, L.L.C., a Nevada limited liability company ("S Company"),
New PanAmSat and HCI, New PanAmSat will acquire from S Company all of the
capital stock of Univisa, Inc., a Delaware corporation ("Univisa"), which is
the indirect holder of all of the outstanding shares of PAS Class B Common
Stock. In connection with the Univisa Contribution, S Company will receive,
for each share of PAS Class B Common Stock indirectly owned by Univisa, at S
Company's election, consideration that is equal in amount and form
 
                                       2
<PAGE>
 
(subject to proration, as applicable) to the consideration payable on account
of each share of PAS Class A Common Stock and PAS Ordinary Common Stock in the
Merger.
 
  Concurrently with the Merger and immediately following the Univisa
Contribution, 7.5 million shares of New PAS Common Stock received by S Company
in connection with the Univisa Contribution will be repurchased by New
PanAmSat for $225 million (the "Share Repurchase"). Following the Share
Repurchase, either Televisa, S Company and/or their designees will purchase
for $225 million all of PanAmSat's rights to purchase equity interests in
certain joint ventures to be formed to offer direct-to-home ("DTH") services
in Latin America and the Iberian Peninsula pursuant to the DTH Option Purchase
Agreement dated September 20, 1996 between PanAmSat, Televisa and S Company.
 
  The affirmative vote of (i) the holders of a majority of the votes of the
outstanding shares of PAS Class A Common Stock and PAS Ordinary Common Stock,
voting together as a single class, and the holders of a majority of the votes
of the outstanding shares of PAS Class B Common Stock and PAS Ordinary Common
Stock, voting together as a single class, as well as (ii) the holders of a
majority of the votes of the outstanding shares of each of the PAS Class A
Common Stock and the PAS Class B Common Stock (as long as the outstanding
shares of PAS Class A Common Stock and/or PAS Class B Common Stock represent
at least 5% of the total outstanding shares of PAS Common Stock), is necessary
to approve the Reorganization Agreement, the Merger Agreement and the Charter
Amendment. In addition, the affirmative vote of the holders of the majority of
votes of the outstanding shares of PAS Class A Common Stock, PAS Class B
Common Stock and PAS Ordinary Common Stock, each voting as a separate class,
is necessary to approve the Charter Amendment. Pursuant to an agreement
executed in connection with the Reorganization Agreement, the beneficial
owners of all issued and outstanding shares of PAS Class A Common Stock and
PAS Class B Common Stock have agreed to vote all of their shares of PAS Common
Stock to approve the Reorganization Agreement, the Merger Agreement and the
Charter Amendment. Immediately before the record date for the Special Meeting,
the holders of PAS Class A Common Stock voluntarily converted the number of
shares of PAS Class A Common Stock necessary to constitute a majority of the
outstanding shares of PAS Ordinary Common Stock from PAS Class A Common Stock
into PAS Ordinary Common Stock (such shares of PAS Ordinary Common Stock, the
"Converted Shares"). On the record date for the Special Meeting, the
beneficial owners of all of the outstanding shares of PAS Class A Common
Stock, PAS Class B Common Stock and the Converted Shares held the voting power
required to approve the Reorganization Agreement, the Merger Agreement and the
Charter Amendment. Accordingly, approval thereof by the PanAmSat stockholders
is assured.
 
  Only holders of record of shares of PAS Common Stock at the close of
business on April 8, 1997, the record date for the Special Meeting, are
entitled to notice of and to vote at the Special Meeting and any adjournments
or postponements thereof. A complete list of the stockholders entitled to vote
at the Special Meeting shall be open to examination of any stockholder, for
any purpose germane to the Special Meeting, during ordinary business hours for

of New PanAmSat, and New PanAmSat and (ii) a proposal to approve and adopt an
amendment (the "Charter Amendment") to the Amended and Restated Certificate of

shares of Class A Common Stock, par value $.01 per share, of PanAmSat (the
"PAS Class A Common Stock") and the
 
                                                       (Continued on next page)

THE SHARES OF COMMON STOCK, PAR VALUE $.01 PER SHARE, OF NEW PANAMSAT (THE

ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION OR ANY STATE SECURITIES
COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROXY

                               ----------------
 
        The date of this Proxy Statement/Prospectus is April 16, 1997.

(Continued from previous page)
 
shares of Class B Common Stock, par value $.01 per share, of PanAmSat (the
"PAS Class B Common Stock") will not convert into shares of Common Stock, par
value $.01 per share, of PanAmSat (the "PAS Ordinary Common Stock") in
connection with the Reorganization Agreement, the Univisa Contribution
Agreement (as defined below) and the transactions contemplated thereby and (C)
clarify that the provisions in the PanAmSat Certificate of Incorporation
regarding the consideration that must be received in a merger, consolidation
or business combination will not apply to the transactions contemplated by the
Reorganization Agreement, the Merger Agreement and the Univisa Contribution
Agreement.
 
  As a result of the transactions contemplated by the Reorganization Agreement
and the Merger Agreement, among other things, at the Effective Time (as
defined below), PAS Merger Corp. will be merged with and into PanAmSat (the
"Merger") and the existing commercial satellite business of the Hughes Parties
will be contributed to New PanAmSat (the "Asset Contribution"), with the
result that: (a) PanAmSat will become a wholly owned subsidiary of New
PanAmSat, (b) each issued and outstanding share of PAS Class A Common Stock
and PAS Ordinary Common Stock will be converted into, at the election of each
holder, either (i) the right to receive an amount in cash equal to $15, plus
one half ( 1/2) share of New PAS Common Stock, (ii) the right to receive
(subject to proration, as applicable) one share of New PAS Common Stock, or
(iii) the right to receive (subject to proration, as applicable) an amount in
cash equal to $30, (c) New PanAmSat will own and operate the existing
commercial satellite business of the Hughes Parties and (d) HCI and certain of
its subsidiaries will receive an aggregate of 106,622,807 shares of New PAS
Common Stock. Assuming that New PanAmSat pays half stock and half cash as
consideration in the Merger and the Univisa Contribution (as defined below),
the shares of New PAS Common Stock received by HCI and certain of its
subsidiaries will represent approximately 71.5% of the outstanding shares of
New PAS Common Stock after the Merger. The Reorganization Agreement and the
Merger Agreement provide that the maximum aggregate cash consideration to be
paid in connection with the Merger and the Univisa Contribution will be equal
to $15 multiplied by the number of shares of PAS Ordinary Common Stock, PAS
Class A Common Stock and PAS Class B Common Stock (collectively, the "PAS
Common Stock") outstanding at the time of the Merger. In addition, if the
closing of the Merger has not occurred on or prior to September 20, 1997, the
cash portion of the consideration payable in the Merger and the Univisa
Contribution will be increased at a rate equal to 9% per annum from September
20, 1997 to the date of the closing of the Merger. Finally, New PanAmSat may
limit the aggregate number of shares of New PAS Common Stock to be issued in
the Merger and the Univisa Contribution to as few as one half ( 1/2) of the
number of shares of PAS Common Stock outstanding at the time of the Merger.
 
  An election to receive all cash in connection with the Reorganization may
result in the receipt of either all cash or, in the event that the aggregate
amount of all elections to receive cash exceeds $15 multiplied by the number
of shares of PAS Common Stock outstanding at the time of the Reorganization, a
combination of cash and shares of New PAS Common Stock. For example, in the
event that all cash is elected by all direct and indirect holders of PAS
Common Stock, each such holder will receive $15 in cash plus one half ( 1/2)
share of New PAS Common Stock on account of each share of PAS Common Stock
held directly or indirectly by such holder.
 
  An election to receive all stock in connection with the Reorganization may
result in the receipt of either all stock or, in the event that (i) the direct
and indirect holders of more than one half ( 1/2) of the number of shares of
PAS Common Stock outstanding at the time of the Reorganization elect to
receive stock on account of such shares and (ii) New PanAmSat exercises its
option to limit the number of additional shares of New PAS Common Stock to be
issued, a combination of cash and shares of New PAS Common Stock. For example,
in the event that all stock is elected by all direct and indirect holders of
PAS Common Stock and New PanAmSat exercises its option to limit the number of
additional shares of New PAS Common Stock to be issued, each such holder will
receive one half ( 1/2) share of New PAS Common Stock plus $15 in cash on
account of each share of PAS Common Stock held directly or indirectly by such
holder. An election to receive $15 in cash and one half ( 1/2) share of New
PAS Common Stock on account of each share of PAS Common Stock will not be
affected by the proration procedures.
 
                                       2
<PAGE>
 
  The impact of the elections on New PanAmSat will depend upon whether such
elections direct New PanAmSat to issue more stock or pay more cash. If more
stock is issued, less debt will be incurred by New PanAmSat, making it less
highly leveraged. If more cash is paid (up to the proration limits), New
PanAmSat will incur more indebtedness as a result of such payments.
 
  Immediately prior to the Merger, in a separate but related transaction (the
"Univisa Contribution"), pursuant to the Stock Contribution and Exchange
Agreement dated as of September 20, 1996 (the "Univisa Contribution
Agreement") among Grupo Televisa, S.A., a Mexican corporation ("Televisa"),
Satellite Company, L.L.C., a Nevada limited liability company ("S Company"),
New PanAmSat and HCI, New PanAmSat will acquire from S Company all of the
capital stock of Univisa, Inc., a Delaware corporation ("Univisa"), which is
the indirect holder of all of the outstanding shares of PAS Class B Common
Stock. In connection with the Univisa Contribution, S Company will receive for
each share of PAS Class B Common Stock indirectly held by Univisa, at S
Company's election, consideration that is equal in amount and form (subject to
proration, as applicable) to the consideration payable on account of each
share of PAS Class A Common Stock and PAS Ordinary Common Stock in the Merger.
 
  Concurrently with the Merger and immediately following the Univisa
Contribution, 7.5 million shares of New PAS Common Stock received by S Company
in connection with the Univisa Contribution will be repurchased by New
PanAmSat for $225 million (the "Share Repurchase"). Following the Share
Repurchase, either Televisa, S Company and/or their designees will purchase
for $225 million all of PanAmSat's rights to purchase from Televisa equity
interests in certain joint ventures to be formed to offer direct-to-home
("DTH") services in Latin America and the Iberian Peninsula (the "DTH
Options"), pursuant to the DTH Option Purchase Agreement dated as of September
20, 1996 (the "DTH Option Purchase Agreement") between PanAmSat, Televisa and
S Company.
 
  The affirmative vote of (i) the holders of a majority of the votes of the
outstanding shares of PAS Class A Common Stock and PAS Ordinary Common Stock,
voting together as a single class, and the holders of a majority of the votes
of the outstanding shares of PAS Class B Common Stock and PAS Ordinary Common
Stock, voting together as a single class, as well as (ii) the holders of a
majority of the votes of the outstanding shares of each of the PAS Class A
Common Stock and the PAS Class B Common Stock (as long as the outstanding
shares of PAS Class A Common Stock and/or PAS Class B Common Stock represent
at least 5% of the total outstanding shares of PAS Common Stock), is necessary
to approve the Reorganization Agreement, the Merger Agreement and the Charter
Amendment. In addition, the affirmative vote of the holders of the majority of
votes of the outstanding shares of PAS Class A Common Stock, PAS Class B
Common Stock and PAS Ordinary Common Stock, each voting as a separate class,
is necessary to approve the Charter Amendment. Pursuant to an agreement
executed in connection with the Reorganization Agreement, the beneficial
owners of all issued and outstanding shares of PAS Class A Common Stock and
PAS Class B Common Stock have agreed to vote all of their shares of PAS Common
Stock in favor of the Reorganization Agreement, the Merger Agreement and the
Charter Amendment. Immediately before the record date for the Special Meeting,
the holders of PAS Class A Common Stock voluntarily converted the number of
shares of PAS Class A Common Stock necessary to constitute a majority of the
outstanding shares of PAS Ordinary Common Stock from PAS Class A Common Stock
into PAS Ordinary Common Stock (such shares of PAS Ordinary Common Stock, the
"Converted Shares"). On the record date for the Special Meeting, the
beneficial owners of all of the outstanding shares of PAS Class A Common
Stock, PAS Class B Common Stock and the Converted Shares held the voting power
required to approve the Reorganization Agreement, the Merger Agreement and the
Charter Amendment. Accordingly, approval thereof by the PanAmSat stockholders
is assured.

                              communications system and currently owns and
                              operates four satellites serving Latin America,
                              the Caribbean, Europe, Asia, the Middle East and

                              services primarily to the broadcasting and

                              business activities. As a result of the Merger
                              and the Univisa Contribution, PanAmSat will
                              become a wholly owned subsidiary of New PanAmSat
                              and, assuming that New PanAmSat pays half stock
                              and half cash as consideration in the Merger and
                              the Univisa Contribution (and giving effect to
                              the Share Repurchase), (i) HCI and certain of its
                              subsidiaries will own approximately 71.5% of the
                              New PAS Common Stock and (ii) the former direct
                              and indirect holders of PAS Common Stock will own
                              approximately 28.5% of New PAS Common Stock. If
                              all of PanAmSat's stockholders elect to receive
                              all stock in the Merger and pursuant to the
                              Univisa Contribution (and giving effect to the
                              Share Repurchase) and New PanAmSat does not
                              exercise its option to limit the number of
                              additional shares of New PAS Common Stock to be
                              issued in lieu of cash to PanAmSat stockholders,
                              (i) HCI and certain of its subsidiaries will own
                              approximately 53.5% of the outstanding shares of
                              New PAS Common Stock and (ii) the former direct
                              and indirect holders of PAS Common Stock will own
                              approximately 46.5% of the outstanding shares of
                              New PAS Common Stock after the Merger. Pursuant
                              to the terms of the Reorganization Agreement, New
                              PanAmSat may exercise its option to limit the
                              number of shares of New PAS Common Stock to be
                              issued, at any time prior to the payment to
                              stockholders pursuant to the elections.

                              or termination of the waiting periods under the
                              Hart-Scott-Rodino Improvements Act of 1976, as
                              amended, and the rules promulgated thereunder
                              (the "HSR Act"). The waiting periods under the
                              HSR Act, however, have expired without a Request

                              In addition, consummation of the Reorganization
                              was conditioned upon, among other things, ap-
                              proval by the Federal Communications Commission
                              (the "FCC") of the transfer of control of
                              PanAmSat and the receipt of other necessary regu-
                              latory approvals. The FCC issued its approval or-
                              der on April 4, 1997 and the applicable appeal
                              period will expire on May 5, 1997. See "THE REOR-

                              General Severance Policy. On April 22, 1996, the
                              PanAmSat Board adopted a general severance policy
                              for all employees upon termination without cause.
                              Under such policy, Frederick A. Landman,
                              President and Chief Financial Officer of
                              PanAmSat, Lourdes Saralegui, Executive Vice
                              President of PanAmSat, Patrick J. Costello, Chief
                              Financial Officer of PanAmSat, James W. Cuminale,
                              Senior Vice President and General Counsel of
                              PanAmSat, and Robert A. Bednarek, Senior Vice
                              President, Engineering and Operations, of
                              PanAmSat (the "Named Executive Officers") would
                              be entitled to receive a minimum of four weeks'
                              salary and a maximum of 52 weeks' salary as
                              severance.
 
                              Employee Separation Plan. On April 22, 1996, the
                              PanAmSat Board adopted an Employee Separation
                              Plan (the "Employee Separation Plan") providing
                              that for a one-year period following a "change of
                              control" (as defined below) any employee who is
                              terminated without cause would be entitled to
                              receive six months' continuation of certain
                              additional benefits. The Employee Separation Plan
                              applies to all employees of PanAmSat, other than
                              any employee that is otherwise covered by a
                              Severance Agreement (as defined below). The
                              Employee Separation Plan is effective for one
                              year and is renewable at PanAmSat's option.
                              PanAmSat has extended the Employee Separation
                              Plan until the first anniversary following the
                              Closing Date.
 
                              Executive Severance Pay Program. On April 22,
                              1996, the PanAmSat Board adopted an executive
                              severance pay program covering the Named
                              Executive Officers and approximately 55 other key
                              employees. Pursuant to severance agreements
                              between PanAmSat and each covered officer,
                              severance benefits are payable to such officers
                              under certain circumstances following a change of
                              control and are determined by multiplying base
                              salary and a cash bonus component by 3 in the
                              case of Mr. Landman, Ms. Saralegui, Mr. Costello,
                              Mr. Cuminale and Mr. Bednarek and by 1.5 in the
                              case of the remaining key employees. Covered
                              officers would be entitled to certain other
                              welfare and insurance benefits until the earlier
                              of (i) 36 months in the case of Mr. Landman and
                              Ms. Saralegui, (ii) 24 months in the case of the
                              remaining three covered officers and (iii) 18
                              months in the case of the remaining key
                              employees, or the obtaining of similar benefits
                              on reemployment. The severance agreements
                              restrict the ability of the Named Executive
                              Officers and remaining key employees to compete
                              with PanAmSat for 18 and 12 month periods
                              following their respective termination from
                              PanAmSat.

                              Stock Incentive Plan. PanAmSat has granted to
                              certain of its employees options to purchase an
                              aggregate of 1,250,000 shares of Common Stock,
                              including grants to Mr. Landman, Ms. Saralegui,
                              Mr. Costello, Mr. Cuminale and Mr. Bednarek for

                              75,000 shares and 75,000 shares, respectively. At
                              the Effective Time, each of the foregoing holders
                              will receive for each share of PAS Ordinary
                              Common Stock subject to such options an amount
                              (subject to applicable withholding tax) in cash
                              equal to the difference between $30 and the per
                              share exercise price of such option. Such options
                              are exercisable at the price of $17 per share.
                              After discussions with HCI, PanAmSat did not
                              grant any new options to its employees in
                              September 1996, the first anniversary of its
                              initial public stock offering, as previously
                              anticipated. Instead, in lieu of such options,
                              PanAmSat paid cash in the aggregate amount of
                              $4.8 million to 195 of its employees, including
                              $950,000 to Mr. Landman, $500,000 to Ms.
                              Saralegui, $300,000 to Mr. Costello, $225,000 to
                              Mr. Cuminale and $225,000 to Mr. Bednarek.
 
                              Indemnification. The Reorganization Agreement
                              provides for certain rights of indemnification,

                              to matters existing or occurring at or prior to

                              and subject to certain conditions, to require New
                              PanAmSat to register all or any portion of the

                              that it will enter into employment agreements
                              with Mr. Landman and Ms. Saralegui on terms and

                              thereto. New PanAmSat also anticipates that for a
                              one-year transition period after the Effective
                              Time, New PanAmSat will pay HE for the services

     predecessor of PanAmSat (the "Partnership"), was not subject to federal or
     state income taxes. Accordingly, no income taxes were deducted from net
     income on the Partnership's financial statements. However, the Partnership
     was obligated under its Partnership Agreement to make certain tax
     distributions to its partners. On March 2, 1995, the Partnership was
     converted to corporate form (the "Conversion") and, accordingly, is now
     subject to income taxes. See "BUSINESS OF PANAMSAT--Conversion and Initial
     Public Offering."
 (3) The following Certain Pro Forma Data gives effect to the Conversion and
     the consummation of the initial public offering of PanAmSat's Common Stock
     on September 20, 1995 (the "IPO") as if each had occurred at January 1,
     1995. See "BUSINESS OF PANAMSAT-- Conversion and Initial Public Offering."
     The pro forma adjustment to income taxes for the periods indicated is
     based on a pro forma statutory tax rate of 40.3%.

   Pro forma loss per share included in the PanAmSat Financial Statements
   appearing elsewhere in this Proxy Statement/Prospectus of $(.08) per share
   for the year ended December 31, 1995 is based on 89,678,638 weighted average
   shares outstanding as of December 31, 1995, reflecting the IPO which
   occurred on September 21, 1995.
 
 (4) Represents earnings before net interest expense, income taxes,
     depreciation and amortization ("EBITDA"). EBITDA is commonly used in the
     communications industry to analyze companies on the basis of operating
     performance, leverage and liquidity. EBITDA should not be considered a
     measure of profitability or liquidity as determined in accordance with
     generally accepted accounting principles in the statements of operations
     and cash flows.
 
 (5) Includes expenses related to the assumption by PanAmSat of phantom stock
     plans of a predecessor company and the grant of a limited partnership
     interest in the Partnership to the Executive Vice President of PanAmSat in
     connection with the corporate reorganization of PanAmSat of $8.3 million
     for the year ended December 31, 1995 and expenses related to the
     Reorganization Agreement and a corporate compensation plan totaling $9.6
     million for the year ended December 31, 1996. EBITDA and EBITDA margin
     excluding such expenses were $74.5 million and 64% for the year ended
     December 31, 1995 and $179.7 million and 73% for the year ended December
     31, 1996. See Notes 11 and 13 of the PanAmSat Financial Statements.
 
 (6) Represents future payments due from customers under long-term contracts at
     the end of the periods indicated, excluding arrangements for satellite
     capacity for DTH services in Latin America. At December 31, 1996,
     approximately $22.6 million of PAS-1 customer payments, $92.4 million of
     PAS-2 customer payments, $35.6 million of PAS-3 customer payments and
     $79.2 million of PAS-4 customer payments were under contracts which are
     terminable by the customer under certain circumstances. Certain contracts
     may also be terminated if certain technical performance specifications
     contained in the agreements, including useful life, are not achieved, or,
     at the customer's option after a minimum service period. Future cash
     payments expected from customers may be reduced for outage or transponder
     failure and may be further reduced for "lowest price" provisions for like
     transponder capacity given to similarly situated customers. The terms of
     PanAmSat's long-term contracts range from one year to the life of the
     satellite. See "PANAMSAT MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
     CONDITION AND RESULTS OF OPERATIONS--Overview."
 
 (7) Excludes, as to each of PAS-5 and PAS-6, a portion of the respective
     purchase prices which will become payable after such satellite is
     delivered and which amount may be paid immediately in cash or deferred
     over periods of up to 15 years with interest rates ranging from 8.0% to
     10.0% per annum. At December 31, 1996, these amounts aggregated
     approximately $34.5 million. A portion of the respective purchase prices
     of PAS-7 and PAS-8 may also be deferrable. PanAmSat presently intends to
     defer such payments at the time they become payable to the extent such
     deferral is permitted under the terms of its then-outstanding indebtedness
     and preferred stock. PanAmSat anticipates that if, at the time such
     payments become payable, PanAmSat is prohibited from incurring such
     indebtedness under the terms of its outstanding indebtedness or preferred
     stock, it will either seek the consent of the holders thereof to incur
     such indebtedness or will obtain funds from sources permitted under the
     terms thereof to make such payments. There can be no assurance that such
     consent will be obtained or that funds will be available to PanAmSat from
     sources permitted under the terms of its outstanding indebtedness and
     preferred stock. See Notes 6, 7 and 8 of the PanAmSat Financial Statements
     appearing elsewhere in this Proxy/Statement Prospectus and "BUSINESS OF
     PANAMSAT--PanAmSat Satellites."

(1) PAS-1 was launched in June 1988 and commenced commercial service in
    November 1988. PAS-2 was launched in July 1994 and commenced commercial
    service in August 1994. PAS-4 was launched in August 1995 and commenced
    commercial service in September 1995. PAS-3 was launched in January 1996
    and commenced commercial service in February 1996. Future launch dates are
    based on PanAmSat estimates.
(2) PanAmSat has entered into a contract with Space Systems/Loral, Inc. for the
    construction and delivery of PAS-6, PAS-7 and PAS-8, with options to
    purchase additional satellites and/or replacement satellites for PAS-7 or
    PAS-8. PAS-6 has been delivered to the launch site. However, SS/Loral has
    recently informed PanAmSat of circumstances that could result in a delay in
    the launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess Weight." The
    contract contemplates delivery of PAS-7 in 1997 and PAS-8 in 1998.
(3) The information for PAS-1, PAS-2, PAS-3 and PAS-4 is based on fuel level
    estimates at January 31, 1997. The information for PAS-5, PAS-6, PAS-7 and
    PAS-8 is based on the terms of their satellite contracts, current mass
    projections and their launch contracts. Based upon current launch vehicle
    capabilities, each of PAS-5, PAS-6 and PAS-8 may have sufficient fuel to
    achieve a significantly longer life, in excess of 20 years. The
    construction design life of each satellite remains 15 years, which
    conservatively is the basis for the predicted life specified above. PAS-7
    also has a design life of 15 years, but SS/Loral has informed PanAmSat that
    it is expected to exceed its contractual weight specifications. To ensure
    that the excess weight does not affect the satellite's intended operational
    lifetime, PanAmSat is exploring several options, including satellite
    modifications by SS/Loral or the use of an alternative Ariane IV launcher
    configuration to deploy the spacecraft.
(4) The application for PAS-5 is pending with the FCC. PanAmSat has received
    conditional regulatory approval for PAS-6, which approval is subject to a
    full financial showing and demonstration of consultation with Intelsat.
(5) PanAmSat has requested FCC approval to co-locate PAS-6 with PAS-3. PanAmSat
    expects to receive final authorization from the FCC to locate PAS-6 at
    43(degrees) W.L. prior to its anticipated launch.
(6) PanAmSat has received conditional regulatory approval for the orbital slot
    of 72(degrees) E.L. from the FCC, which approval is subject to a full
    financial showing and demonstration of consultation with Intelsat. In
    addition, PanAmSat has requested approval to co-locate a satellite with
    PAS-4 at 68.5(degrees) E.L. PanAmSat intends to locate PAS-7 at the
    68.5(degrees) E.L. orbital location if its application for such orbital
    location is granted, in which case the 72(degrees) E.L. orbital slot could
    be used for another satellite. PanAmSat tentatively plans to locate PAS-8
    at 194(degrees) W.L. and has an application for that orbital slot pending
    with the FCC.
(7) Satellite transponders receive transmissions from Earth and relay them back
    to Earth. Transponders are composed of receivers, preamplifiers, power
    amplifiers, frequency shifters and a host of other electronics. C-band and
    Ku-band are ranges of frequencies used worldwide for commercial satellite
    communications. The C-band frequency is widely used for the distribution of
    television programming. The Ku-band frequency is widely used for DTH
    television broadcasting, satellite news-gathering applications and on-site
    business communications networks that require the use of very small
    antennas. Construction of PAS-6 has been completed and it has been
    delivered to the launch site. However, SS/Loral has recently informed
    PanAmSat of circumstances that could result in a delay in the launch of
    PAS-6. See "RISK FACTORS--Risk of Delays; Excess Weight." The designs of
    PAS-5 and PAS-7 are complete. The design for PAS-8 is still to be
    completed.

<PAGE>
 
 
(8) Bandwidth is one measure of the information carrying capacity of a
    transponder. A transponder's bandwidth and power together determine the
    amount of information that can be carried. Construction of PAS-6 has been
    completed and it has been delivered to the launch site. However, SS/Loral
    has recently informed PanAmSat of circumstances that could result in a
    delay in the launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess
    Weight." The designs of PAS-5 and PAS-7 are complete. The design for PAS-8
    is still to be completed.
(9) Output power is the transmitter power of each transponder and is not a
    measure of the signal power received on Earth. Total output power is the
    aggregate power of all the transponders on the satellite. High output power
    allows for the use of smaller and less expensive receiving antennas to
    obtain the satellite signal. Construction of PAS-6 has been completed and
    it has been delivered to the launch site. However, SS/Loral has recently
    informed PanAmSat of circumstances that could result in a delay in the
    launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess Weight." The
    designs of PAS-5 and PAS-7 are complete. The design for PAS-8 is still to
    be completed.

 (1) The expected end of useful life for each of Galaxy's operational
     satellites (other than SBS 4) is based on a fuel level estimate at
     December 31, 1996. The expected end of useful life for SBS 4 is based on
     the degree of its north-south inclination at December 31, 1996.
 (2) Satellite transponders receive transmissions from Earth and relay them
     back to Earth. Transponders are composed of receivers, preamplifiers,
     power amplifiers, frequency shifters and a host of other electronics.
 (3) Ku-band is a range of relatively high frequencies (between approximately
     12 GHz and 14 GHz) used for commercial satellite communications. Ku-band
     is widely used for distribution of broadcast television and DTH services,
     as well as business communications, and allows for the use of relatively
     small receive antennas.
 (4) C-band is a range of relatively low frequencies (between approximately 4
     GHz and 6 GHz) used for commercial satellite communications. C-band is
     used primarily for cable and broadcast distribution and requires the use
     of relatively large receive antennas on the ground.
 (5) Bandwidth is one measure of the information carrying capacity of a
     transponder. A transponder's bandwidth and power together determine the
     amount of information that can be carried.
 (6) Output power is the transmitter power of each transponder and is not a
     measure of the signal power received on Earth. High output power allows
     for the use of smaller and less expensive receive antennas to obtain a
     satellite signal.
 (7) Satellite operators may opt to extend the life of a satellite by allowing
     it to move into a fuel-conserving mode called "inclined orbit." When a
     satellite is put into inclined orbit, only east-west station-keeping is
     continued. While in this mode, the satellite moves in a figure-8 crossing
     the equator twice daily. The uncorrected north-south inclination increases
     over time and certain customers must retrofit their existing ground
     equipment or purchase new equipment to enable them to track the movement
     of the satellite. After reaching a certain degree of north-south
     inclination, tracking antennas can no longer reliably follow the movement
     of the satellite and its useful life ends.
 (8) The expected end of useful life for each of Galaxy's expected future
     satellites is based on the terms (with respect to Galaxy VIII-i and Galaxy
     X) or anticipated terms (with respect to Galaxy XI, Galaxy XIII-i and
     Galaxy XIV-i) of the relevant satellite construction contract and the
     terms (with respect to Galaxy VIII-i, Galaxy X and Galaxy XI) or
     anticipated terms (with respect to Galaxy XIII-i and Galaxy XIV-i) of the
     relevant satellite launch arrangement.

           SUMMARY UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
  The Summary Unaudited Pro Forma Combined Financial Statements of New PanAmSat
as of and for the year ended December 31, 1996 have been derived from the
PanAmSat Financial Statements and the Galaxy Financial Statements, combined to
give effect to the Merger, the Univisa Contribution (including the Share
Repurchase) and the Asset Contribution, as if such transactions had occurred at
January 1, 1996 for purposes of the Unaudited Pro Forma Combined Statement of
Income and on December 31, 1996 for purposes of the Unaudited Pro Forma
Combined Balance Sheet, applying the purchase method of accounting with Galaxy
as the acquirer of PanAmSat.
 
  The following Unaudited Pro Forma Combined Financial Statements do not
purport to present information regarding the financial position or results of
operations of New PanAmSat had the transactions and events assumed therein
occurred on the dates specified, nor information that is necessarily indicative
of the results of operations that may be achieved in the future. The Unaudited
Pro Forma Combined Statement of Income does not give effect to (i) any cost
savings that may be realized as a result of the combination of the two
companies or (ii) nonrecurring costs that may be incurred after the
Reorganization is consummated, consisting primarily of expenses related to
relocating employees and modifying facilities. The significance of such
potential cost savings and nonrecurring cost increases will depend on how New
PanAmSat decides in the future to structure its operations. The Unaudited Pro
Forma Combined Financial Statements are based on certain assumptions and
adjustments described in the Notes to Unaudited Pro Forma Combined Financial
Statements and should be read in conjunction therewith and with "THE
REORGANIZATION," "PANAMSAT MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS," "GALAXY MANAGEMENT'S DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" and the PanAmSat
Financial Statements and Galaxy Financial Statements appearing elsewhere in
this Proxy Statement/Prospectus.

                                 RISK FACTORS
 
  This Proxy Statement/Prospectus contains certain forward-looking statements
as defined in the Private Securities Litigation Reform Act of 1995. The
following factors, among others, could cause actual results to differ
materially from those contained in such forward-looking statements. When used
in this Proxy Statement/Prospectus, and in the documents incorporated by
reference herein, the words "estimate," "project," "anticipate," "expect,"
"intend," "believe" and similar expressions are intended to identify forward-
looking statements. In addition, the following important factors should be
considered by the holders of shares of PAS Common Stock in connection with any
decision made with respect to the matters to be voted upon at the Special
Meeting.
 
  Risk of Launch Failure. Satellites are subject to significant launch risks,
including launch failure, destruction and damage, which prevent proper
commercial operation and cause incorrect orbital placement. Since September
1991, approximately 12% of all commercial geosynchronous satellites have
experienced a launch failure, failure to achieve geosynchronous orbit from
transfer orbit or failure to operate upon reaching orbit. The launch failure
rate varies by launch vehicle and manufacturer. Of the five satellite launches
by PanAmSat since 1988 and the 17 satellite launches by Galaxy since 1983,
PanAmSat has experienced one launch failure and Galaxy has experienced two
launch failures: on December 1, 1994, PanAmSat's third satellite, the original
PAS-3, was destroyed upon launch as a result of a malfunction of an Ariane IV
launch vehicle; on August 22, 1992, Galaxy's original Galaxy I-R satellite was
destroyed upon launch as a result of an Atlas launch vehicle malfunction; and
Galaxy's Leasat 4, which was launched on August 27, 1985, never became
operational due to the failure of its communications payload. Each of PAS-3,
Galaxy I-R and Leasat 4 was insured in an amount sufficient to construct,
launch and insure a replacement satellite, and each was subsequently replaced
with a satellite that was successfully launched on January 12, 1996, February
19, 1994 and January 9, 1990, respectively. There can be no assurance that any
future launches of satellites owned by PanAmSat, Galaxy or New PanAmSat will
be successful. An unsuccessful launch of any of New PanAmSat's future
satellites could have a material adverse effect on New PanAmSat.
 
  Certain launch vehicles scheduled to be used by PanAmSat and Galaxy have
unproven track records and are susceptible to certain risks associated with
new launch vehicles. For example, PanAmSat may launch PAS-7 on an Ariane IV or
Ariane V rocket. On June 4, 1996, the maiden flight of the Ariane V launch
vehicle ended in failure and there can be no assurance that future Ariane V
launches will be reliable. Arianespace S.A. ("Arianespace") is going forward
with the development of Ariane V, but the timing of the availability of the
Ariane V launch vehicle for commercial launches is uncertain. In the event
that the Ariane V program is delayed, PanAmSat has contractual rights that
could be used to maintain the launch of PAS-7 substantially on schedule.
PanAmSat expects to launch PAS-5 and PAS-8 on a Proton launch vehicle. On
November 17, 1996, a Proton launch vehicle suffered a launch failure, the
second such failure in 1996. Preliminary indications are that the failure may
have been caused by the satellite and not the launcher, and as such PanAmSat
does not believe that such failure will cause any delay to future PanAmSat
launches or Proton launches. An investigation of the failure has commenced,
but a final report has not been issued. Likewise, Galaxy plans to launch
Galaxy X on a McDonnell Douglas Corporation ("MDC") Delta III rocket, which,
like the Ariane V rocket, has never before been used to launch a satellite. On
January 17, 1997, a Delta II launch vehicle (the previous generation of Delta
launch vehicles) suffered a launch failure. An investigation into the failure
has commenced, and pending the report of such investigation, MDC has given
notice that there may be delays requiring an extension of the launch schedule.
In addition, Galaxy XI will be the first commercial launch by Sea Launch Co.,
a newly-formed venture among Boeing Commercial Space Co. (United States),
Kvaerner a.s. (Norway), RSC-Energia (Russia) and NPO-Yuzhnoye (Ukraine), which
plans to launch satellites from a newly-developed, ocean-going platform. There
can be no assurance that Galaxy's planned launch on the Delta III rocket or
Galaxy's planned launch using the Sea Launch Co. platform will be successful.
 
  PanAmSat and Galaxy also are susceptible to certain risks associated with
utilizing launch vehicles constructed by companies located in or launching
from locations within Russia and other republics of the former Soviet Union.
The launch vehicle to be used for Galaxy XI in connection with the Sea Launch
Co. platform is a Ukrainian-built Zenit rocket. PanAmSat plans to launch PAS-
5, PAS-8 and possibly future satellites utilizing a
 
                                      34
<PAGE>
 
Russian-built Proton rocket provided by Lockheed-Khrunichev-Energia
International, Inc. (now known as International Launch Services) ("LKE"). A
U.S.-constructed satellite that is to be launched outside of the United States
requires an export license from the U.S. government. Additionally, launches by
a Russian launch company, including those by LKE, are governed by a United
States-Russia launch agreement, which contains certain restrictions as to the
number and pricing of Russian launches. Either of these requirements could
result in denial of permission, or unacceptable delay in granting permission,
to launch a satellite in a republic of the former Soviet Union. In addition to
the risk of not being able to obtain permits required to launch from former
Soviet republics and using previously untested technology (such as the Sea
Launch Co. launch platform), the evolving nature of the governmental,
political, social and legal structures within Russia and the Ukraine create
additional risks. Changes in policies of the Russian and Ukrainian governments
or the political leadership of such governments may have a significant adverse
impact on the political and economic environment in such countries. Because
the governmental and legal systems in Russia and the Ukraine are evolving and
untested, there is and will continue to be uncertainty concerning the value,
transferability and enforceability of the contract rights which PanAmSat and
Galaxy may acquire. Moreover, economic reforms could result in further
political or social instability. Any political or social instability could
affect the cost, timing and overall advisability of using a Russian-built
Proton rocket, a Ukrainian-built Zenit rocket or a Russian launch provider. In
the event that a launch scheduled with a Russian launch provider or Ukranian
rocket becomes unavailable or impractical, PanAmSat and Galaxy believe that
alternative launch arrangements would be available. There can be no assurance,
however, that such alternative launch arrangements would not result in delay
or additional expense to New PanAmSat.
 
  PanAmSat and Galaxy typically have insured satellite launches for an amount
sufficient to construct, launch and insure a replacement satellite, and
PanAmSat and Galaxy expect that New PanAmSat will continue to purchase such
insurance for its future satellites. PanAmSat already has obtained insurance
in an amount sufficient to cover the construction, launch and insurance costs
for PAS-5, PAS-6, PAS-7 and PAS-8 and an additional satellite that would be
used in case of loss of any of the foregoing satellites or to be launched as
PAS-9 if none of the aforementioned satellites fail (hereafter "PAS-9/R").
Galaxy recently obtained insurance in an amount sufficient to cover the
construction, launch and insurance costs for Galaxy VIII-i, but has not yet
obtained launch insurance for any of its other future launches. Launch
insurance typically does not cover lost operating revenues or customers, and,
depending on individual customer contracts, the delay of service caused by a
launch failure may result in the loss of customers that pre-booked transponder
capacity. A launch failure, to the extent that insurance proceeds are
inadequate to compensate for losses resulting therefrom, could have a material
adverse effect on New PanAmSat and any such failure could significantly delay
the ability of New PanAmSat to expand its satellite fleet.
 
  Risk of In-Orbit Failure. Satellites are also subject to risks after they
have been properly deployed and are operational. Over the period from 1989 to
1996, the risk of an insured commercial satellite failing prematurely due to,
among other things, mechanical failure, a collision with objects in space or
an inability to maintain proper orbit was approximately 1.6%. More recently,
in January 1997, AT&T Corp.'s Skynet Satellite Services lost its Telstar 401
satellite to an in-orbit failure. The likelihood of in-orbit failure may be
heightened by PanAmSat's and Galaxy's use on certain of their satellites of
new satellite technology, including PanAmSat's use of a new xenon ion
propulsion system ("XIPS") on PAS-5, and Galaxy's use of XIPS on Galaxy VIII-
i, Galaxy XI, Galaxy XIII-i and Galaxy XIV-i. In addition, Galaxy's planned
deployment of new HS 702 model satellites may increase the risk of such
failure. See "BUSINESS OF PANAMSAT--PanAmSat Satellites" and "BUSINESS OF
GALAXY--Galaxy Satellites." Neither PanAmSat nor Galaxy has ever experienced
an in-orbit failure of a satellite as a whole or any major nonredundant
subsystem after it achieved full operational capability and prior to the end
of its expected life, but both PanAmSat and Galaxy maintain in-orbit insurance
in order to mitigate in-orbit risks. For each PanAmSat or Galaxy satellite,
PanAmSat or Galaxy, as the case may be, purchases in-orbit insurance coverage
calculated to avoid, at a minimum, a book loss in the event of a casualty. The
amount of this coverage, however, is not sufficient to construct, launch and
insure a replacement satellite. New PanAmSat's future practices with regard to
the amount of in-orbit insurance coverage have not yet been determined, but
New PanAmSat is likely to maintain at least enough insurance to protect
against a book loss in the event of the in-orbit failure of one of its
satellites. In-orbit satellite insurance purchased by PanAmSat, Galaxy
 
                                      35
<PAGE>
 
or New PanAmSat will not compensate for business interruption and similar
losses (including, among other things, loss of operating revenue and
incidental and consequential damages) which might arise from the in-orbit
failure of a satellite. In addition, PanAmSat's and Galaxy's in-orbit and
launch insurance policies typically include customary commercial satellite
insurance exclusions including, among other things, damage or loss caused by
military actions or acts of war, anti-satellite devices, government action,
frequency interference or nuclear reaction. Damage to or loss of a satellite
that is excluded from coverage under New PanAmSat's insurance policies could
have a material adverse effect on New PanAmSat. See "BUSINESS OF PANAMSAT--
Insurance" and "BUSINESS OF GALAXY--Insurance."
 
  Risk of Satellite Damage or Loss from Acts of War, Electrostatic Storm and
Space Debris. The loss, damage or destruction of any of PanAmSat's, Galaxy's
or New PanAmSat's satellites as a result of military actions or acts of war,
anti-satellite devices, electrostatic storm or collision with space debris
would have a material adverse effect on New PanAmSat. PanAmSat's and Galaxy's
insurance policies include customary exclusions, including for (i) military or
similar actions, (ii) laser, directed-energy or nuclear anti-satellite
devices, (iii) insurrection and similar acts or governmental action to prevent
such acts, (iv) governmental confiscation, (v) nuclear reaction or radiation
contamination, (vi) willful or intentional acts of PanAmSat, Galaxy or their
respective contractors, (vii) loss of market, loss of revenue, extra expenses,
incidental and consequential damages, (viii) third-party claims against
PanAmSat or Galaxy and (ix) electromagnetic or radio frequency interference,
except for physical damage to a satellite directly resulting from such
interference.
 
  Risk of Delays; Excess Weight. A significant delay in the delivery or launch
of any of New PanAmSat's future satellites would adversely affect New
PanAmSat's marketing plan for such satellite. Such a delay can result from the
construction of satellites and launch vehicles, launch failures, the periodic
unavailability of reliable launch opportunities and possible delays in
obtaining regulatory approvals. If satellite construction schedules are not
met, there can be no assurance that a launch opportunity will be available at
the time a satellite is ready to be launched. The occurrence of a launch
failure would result in a more significant delay in the deployment of a
particular satellite because of the need both to construct a replacement
satellite and obtain another launch opportunity. New PanAmSat also must obtain
authorizations from the FCC to launch and operate satellites, and there can be
no assurance that New PanAmSat will obtain such authorization in a timely
manner. A significant delay in the launch of any of PanAmSat's or Galaxy's
satellites could enable customers who have pre-purchased or agreed to lease
capacity of such satellite to terminate their contracts. Such a delay also
could adversely affect the ability of New PanAmSat to expand the existing
PanAmSat and Galaxy satellite fleets as currently contemplated.
 
  Certain recent events have occurred that will cause PanAmSat's launch of
PAS-5 and PAS-7 to be delayed, although PanAmSat does not believe that there
is a substantial risk to its ability to launch its satellites within the time
limits required by its existing customer contracts. The launch of PAS-5 has
been rescheduled for July 1997 to allow time for Hughes Aircraft Company
("HAC"), which is building PAS-5, to secure certain satellite subcomponents,
the production of which has been delayed. There can be no assurance that
SS/Loral or HAC will be able to meet the applicable revised schedules.
PanAmSat expects completion and delivery of PAS-7 in December 1997 followed by
an anticipated launch in the first quarter of 1998. In addition to the revised
delivery schedule, SS/Loral has informed PanAmSat that it expects that the
satellite will exceed its contractual weight specifications. To ensure that
the excess weight does not affect the satellite's intended operational
lifetime of approximately 15 years, PanAmSat is exploring several options,
including satellite modifications by SS/Loral or the use of an alternative
Ariane IV launcher configuration to deploy the spacecraft. There can be no
assurance that SS/Loral will be able to reduce the mass of the satellite from
its current projections or that PanAmSat will be able to reach an agreement
with Arianespace on the terms or timing of a more powerful launch than
currently specified in PanAmSat's launch contract.
 
  The launch of PAS-6 has been rescheduled for May 1997 to allow time for
Space Systems/Loral, Inc. ("SS/Loral"), which built PAS-6, to replace the
power control units on the spacecraft. Construction of PAS-6 has been
completed and it has been delivered to the launch site. Additionally, SS/Loral
has recently informed
 
                                      36
<PAGE>
 
PanAmSat of circumstances that have developed which could affect the power
system of PAS-6. The matter is under investigation and could result in a delay
in the launch. This situation could result in a delay in the launch of PAS-6
and may require the return of the spacecraft to SS/Loral's facilities for
further testing or other work. In the event the spacecraft is required to be
returned to SS/Loral, rescheduling of the launch of PAS-6 with Arianespace
will be required. There can be no assurance that SS/Loral will be able to
resolve the matter within the time available to maintain the current launch
schedule and, if it is unable to maintain the current schedule, there can be
no assurance that a new launch opportunity for the satellite will be available
from Arianespace in order to avoid additional delay. PanAmSat believes that
there is sufficient time to resolve this matter within the time period
required by its existing customer contracts.
 
  Competition and Market Demand. The telecommunications industry is highly
competitive. PanAmSat and Galaxy face, and New PanAmSat will face, competition
from other satellite companies and from other telecommunications companies
which offer competing services using satellites or terrestrial facilities.
Many of these existing and potential competitors have or could have equal or
greater resources than PanAmSat, Galaxy and New PanAmSat and some of these
competitors are government-sponsored. Increased competition may also result
from: (i) a recent FCC decision that allows all U.S.-licensed satellite
operators to provide service anywhere within their coverage areas, (ii) a
pending proceeding in which the FCC has proposed to codify the terms under
which foreign licensed satellite systems may serve the United States and (iii)
a World Trade Organization agreement pursuant to which the United States has
committed to further opening its telecommunications market, including its
satellite services markets, with the exception of DTH and direct broadcast
satellite services, to foreign-owned and foreign-licensed competitors from
World Trade Organization countries.
 
  PanAmSat faces and New PanAmSat will face significant competition in the
provision of international satellite services. Intelsat, an international
consortium owned by 140 governments ("Intelsat"), provides satellite services
around the world with a fleet of 24 satellites and is presently considering
privatizing all or part of its operations. In February 1996, Comsat
Corporation ("Comsat") and the Clinton Administration agreed to submit a
proposal to Intelsat regarding a restructuring that would divide Intelsat into
two separate entities through the creation of a new Intelsat affiliate
company. Intelsat is also considering other proposals and is expected to take
up the issue of restructuring at the 1997 meeting of its member governments.
If the proposal or any other proposal on restructuring is approved and an
affiliate company of Intelsat is established, this could result in increased
competition to PanAmSat and New PanAmSat. In addition, PanAmSat faces an
increasing number of competitors in each region where PanAmSat conducts its
business, from foreign, domestic, national and regional systems. See "BUSINESS
OF PANAMSAT--Competition." Galaxy faces and New PanAmSat will face significant
competition in the provision of satellite services to the United States. GE
American Communications, Inc., ("GE Americom"), Comsat and Loral SpaceCom
Corporation ("Loral SpaceCom") are all competitors of Galaxy. Also, Loral
SpaceCom recently acquired AT&T Corp.'s Skynet Satellite Services business,
making Loral SpaceCom a more formidable direct competitor of New PanAmSat. In
addition, subject to meeting certain financial requirements, Orion Network
Systems, Inc. and Echostar Communications Corporation have been authorized by
the FCC to construct, launch and operate satellites to serve the United States
and may compete with New PanAmSat in the future. See "BUSINESS OF GALAXY--
Competition."
 
  The satellites of PanAmSat and Galaxy have been, and those of New PanAmSat
will continue to be, designed to satisfy future demand for their services. As
a result, it is likely that most of the future satellites of New PanAmSat,
notwithstanding pre-launch marketing efforts, will have excess available
capacity at the time of their launch. If the expanding supply of
telecommunications services, including those of PanAmSat and Galaxy, exceeds
the demand for such services, such overcapacity could have a negative impact
on New PanAmSat's operating results. To the extent that New PanAmSat's
competitors offer services that are more sophisticated, cost-effective,
efficient or reliable than those now offered or to be offered by PanAmSat or
Galaxy, such competing services also could have a material adverse effect on
New PanAmSat's operations. Further, New PanAmSat's satellites may face
increasing competition from other technologies, including fiber optic cable
technology, which could reduce the demand for New PanAmSat's satellite
services. See "BUSINESS OF PANAMSAT--Competition" and "BUSINESS OF GALAXY--
Competition."

  Regulatory Risks. The satellite industry is highly regulated both in the
United States and internationally. New PanAmSat will be subject to the
regulatory authority of the U.S. government (primarily the FCC) and the
national communications authorities of the countries in which it operates. The
business prospects of New PanAmSat could be adversely affected by the adoption
of new laws, policies or regulations, or changes in the interpretation or
application of existing laws, policies and regulations, that modify the
present regulatory environment. While PanAmSat and Galaxy have generally been
successful in obtaining necessary licenses, there can be no assurance that New
PanAmSat will succeed in obtaining all requisite regulatory approvals for the
construction, launch and operation of any of New PanAmSat's future satellites
and for the orbital slots planned for these satellites or, if obtained, that
such licenses will not impose operational restrictions on New PanAmSat. Nor
can there be any assurance that New PanAmSat will succeed in coordinating any
or all of its future satellites internationally.
 
  In furtherance of their business plans, each of Galaxy and PanAmSat
currently has applications pending before the FCC for authorizations for new
and replacement satellites at various orbital locations. As part of the
regulatory process for orbital slot allocation, PanAmSat and Galaxy are
required to engage in frequency coordination with other satellite operators.
Although PanAmSat has been able to coordinate PAS-1, PAS-2 and PAS-3 and
Galaxy has been able to coordinate its existing satellites, there can be no
assurance that satisfactory coordination will be achieved for any of
PanAmSat's, Galaxy's or New PanAmSat's future satellites. In addition, up to
one half of the C-band transponders on PAS-4 overlap in frequency with a
Russian satellite operating at 70(degrees) E.L. PanAmSat, under the auspices
of the U.S. government, has attempted to coordinate PAS-4 and the Russian
satellite with the Russian authorities. The Russian authorities, however, have
refused to provide full technical information regarding the satellite and
claim that PAS-4 interferes with the Russian satellite. The Russian
authorities have filed a complaint with the International Telecommunications
Union (the "ITU") and have requested that the U.S. authorities require
PanAmSat to cease the alleged interference. The U.S. government has challenged
the Russian authorities' claim of interference and has urged the Russian
authorities to provide additional technical information regarding the
satellite and to proceed with coordination. The ITU has declined to rule
against PanAmSat and has referred the matter to the parties for further
coordination efforts. PanAmSat believes that PAS-4 and the Russian satellite
could be coordinated successfully with reduced adverse effects on PAS-4
capacity. However, until coordination is completed successfully, PanAmSat's
ability to provide services in Russia or to Russian customers will be affected
adversely, both technically and politically. It is PanAmSat's belief that the
Russian authorities have taken the position that they will not license within
Russia the use of the PanAmSat satellites. If PAS-7 is to be co-located with
PAS-4, it is unlikely that PAS-7 will be permitted to operate its C-band
transponders for commercial use until the above described coordination issues
with Russia have been resolved successfully. Also, the governments of Tonga
and Papua New Guinea have filed notices of intended use which conflict with
the registrations for PAS-2, PAS-4 and PAS-8. PanAmSat believes that these
notices are not likely to have any material impact on its ability to provide
service on PAS-2, PAS-4 and PAS-8.
 
  Satellite companies, including Galaxy and PanAmSat, increasingly are
attempting to expand the range of usable frequencies for satellite
communications as the frequencies that traditionally have been used for fixed
satellite services are becoming saturated at desirable orbital locations. Some
of the new frequencies are subject to special coordination requirements, and
there can be no assurance that Galaxy, PanAmSat or New PanAmSat will be able
to satisfy these requirements without there being a material adverse effect on
New PanAmSat's business. For example, the frequencies that are intended to be
used to uplink to PAS-7 and PAS-6 include frequencies in the 13.75-14.0 GHz
band, which constitute approximately 33% of the frequencies on PAS-6 and
approximately 80% of the Ku-band frequencies on PAS-7. These frequencies must
be coordinated with the U.S. government on an earth-station-by-earth-station
basis to insure that harmful interference to primary government operations is
minimized. PanAmSat presently is undertaking such coordination and believes
that it will be able to coordinate successfully with federal government users.
While PanAmSat believes that it will successfully coordinate with such earth
stations or will institute operational solutions that will mitigate the
problem, there can be no assurance that PanAmSat's efforts will be successful.
See "BUSINESS OF PANAMSAT--Government Regulation--Authorizations to Construct,
Launch and Operate Satellites." Similarly, certain of Galaxy's FCC
applications request authority to make use of certain Broadcast Satellite
Services ("BSS") frequencies at twelve
 
                                      38
<PAGE>
 
orbital locations. Uses of the BSS frequency bands at particular orbital
locations have been assigned to countries in accordance with the ITU's BSS
band plan. Under the ITU's regulations, satellite operators also can make
additional uses of BSS frequencies, provided that those uses do not interfere
with the uses set forth in the ITU BSS band plan. In light of the fact that
use of the BSS frequencies in accordance with Galaxy's FCC applications is
such an additional use, Galaxy's use of the BSS frequencies must not
unacceptably interfere with the planned and existing BSS systems by any more
than the degree permitted under the ITU's regulations. While Galaxy believes
that its use of such frequencies can be conducted on an acceptable
interference basis consistent with the ITU's regulations, there can be no
assurance that the ITU will modify the BSS band plan to accommodate such use
or that the FCC will authorize Galaxy to use the BSS frequencies at all or any
of the requested locations. See "BUSINESS OF GALAXY-- Government Regulation--
International Telecommunications Union Coordination."
 
  Regulatory schemes in countries in which PanAmSat operates, or New PanAmSat
may seek to operate, may impose impediments on PanAmSat's or New PanAmSat's
operations. PanAmSat, its customers or companies with which PanAmSat does
business must have authority from each country in which PanAmSat provides
services. Although PanAmSat believes that it, its customers and/or companies
with which it does business presently hold the requisite licenses and
approvals for the countries in which PanAmSat currently provides services, the
regulatory schemes in each country are different and thus there may be
instances of noncompliance of which PanAmSat is not aware. In addition,
portions of PanAmSat's future satellites are being designed to provide service
to countries in which regulatory impediments continue to exist. Although
PanAmSat believes these regulatory schemes will not prevent New PanAmSat from
pursuing its business plan, there can be no assurance that any current
regulatory approvals held by PanAmSat are, or will remain, sufficient in the
view of foreign regulatory authorities, or that any additional necessary
approvals will be granted on a timely basis, or at all, in all jurisdictions
in which PanAmSat or New PanAmSat wishes to operate its new satellites or that
restrictions applicable thereto will not be unduly burdensome.
 
  Risks from International Operations. PanAmSat derives and New PanAmSat will
derive substantial revenues by providing international telecommunication
services. Such operations are subject to certain risks such as changes in
domestic and foreign government regulations and telecommunications standards,
licensing requirements, tariffs, taxes and other trade barriers, exchange
controls and political and economic instability, including fluctuations in the
value of foreign currencies which may make payment in U.S. dollars more
expensive for foreign customers.
 
  Substantial Leverage and Additional Capital Requirements. At December 31,
1996, PanAmSat had outstanding long-term indebtedness of approximately $626.0
million (excluding vendor financing that PanAmSat intends to incur if
permitted by the terms of its outstanding indebtedness and preferred stock as
satellites are launched or become operational) and the 12 3/4% Mandatorily
Exchangeable Senior Redeemable Preferred Stock of PanAmSat (the "PAS Preferred
Stock") with an aggregate liquidation preference of approximately $329
million, which PAS Preferred Stock PanAmSat currently expects will be
exchanged for debt securities in the third quarter of 1997. The indentures
governing PanAmSat's outstanding debt and the certificate of designation for
outstanding PAS Preferred Stock contain, and the indenture that will be
entered into in connection with the issuance of the debt securities to be
issued in exchange for the PAS Preferred Stock will contain, various financial
and operating covenants that, among other things, restrict PanAmSat's ability
to borrow funds or guarantee borrowings of New PanAmSat, restrict the payment
of dividends, other distributions or the redemption of capital stock and other
restricted payments to its stockholders, including New PanAmSat, restrict
transactions with affiliates, restrict the use of proceeds from the sale of
assets, restrict the merger, consolidation or sale of PanAmSat or the sale of
substantially all of the assets of PanAmSat and restrict the ability of New
PanAmSat to use the assets of PanAmSat as collateral for any new borrowing.
PanAmSat presently anticipates that its indebtedness and the PAS Preferred
Stock will remain outstanding following the consummation of the transactions
contemplated by the Reorganization Agreement and the Univisa Contribution
Agreement.
 
  At the Effective Time, New PanAmSat will be obligated to pay up to
approximately $1.5 billion to holders of PAS Ordinary Common Stock and PAS
Class A Common Stock, holders of options to acquire PAS Ordinary
 
                                      39
<PAGE>
 
Common Stock and S Company as the cash portion of the consideration payable in
connection with the Merger and the Univisa Contribution, and pay an additional
$225 million in the Share Repurchase. Pursuant to the Assurance Agreement, HE
has agreed to loan up to $1.725 billion to New PanAmSat (the "New Financing").
The terms of the New Financing will be comparable to the terms that New
PanAmSat would obtain from a third-party commercial lender. Although the
precise terms have not been finalized, the New Financing is expected to be in
the form of a three year term loan that will be fully negotiated prior to the
Closing Date. The New Financing will include covenants that prohibit or limit,
among other things, transactions with affiliates and pledges of New PanAmSat's
assets and will require that New PanAmSat and its subsidiaries maintain a
certain minimum consolidated net worth. Because the indentures governing
PanAmSat's existing debt and the certificate of designation for the PAS
Preferred Stock restrict the ability of PanAmSat to pay dividends to New
PanAmSat, prohibit the use of PanAmSat's assets as collateral for any new
borrowing and restrict PanAmSat's ability to guarantee indebtedness of others,
the terms of the New Financing are less favorable to New PanAmSat than if New
PanAmSat were able to borrow against the consolidated credit of PanAmSat and
Galaxy. As a result of the New Financing, the existing PanAmSat indebtedness
and the PAS Preferred Stock, New PanAmSat will be highly leveraged. The
restrictions contained in the loan documents for the indebtedness of New
PanAmSat (including the indebtedness of its subsidiaries), in combination with
the leveraged nature of New PanAmSat, could limit the ability of New PanAmSat
to respond to market conditions or to engage in certain business activities.
 
  PanAmSat and Galaxy currently have substantial capital programs in place for
constructing, launching and insuring future satellites. On the Closing Date,
assuming PAS-6 is successfully launched as scheduled, PanAmSat and Galaxy
together will have nine satellites under various stages of development for
which PanAmSat and Galaxy have budgeted capital expenditures. PanAmSat will
require approximately $330 million following the Closing Date for the
construction, insurance and launch of PAS-5, PAS-6, PAS-7 and PAS-8.
Similarly, Galaxy will require approximately $743 billion following the
Closing Date to complete construction, insurance and launch of Galaxy VIII-i,
Galaxy X, Galaxy XI, Galaxy XII, Galaxy XIII-i and Galaxy XIV. Galaxy and
PanAmSat currently are discussing whether certain changes should be made to
the technical specifications and locations of certain of their satellites
under development in order to better serve the business objectives of New
PanAmSat, which changes may impact the amount and timing of future capital
expenditures made by New PanAmSat and PanAmSat. The aggregate amount of cash
needed to fund development of all of PanAmSat's and Galaxy's satellites is
expected to be funded from cash on hand and cash flow of the consolidated
operations of New PanAmSat and PanAmSat. In addition to funding new
satellites, New PanAmSat also expects to exercise options under Galaxy's sale-
leaseback arrangements to purchase all of the transponders subject to such
leases at a purchase price equal to the fair market value of such transponders
at such time before the end of the initial term of such lease at a specified
purchase price (the "Early Buy Out Option"), which exercise will require New
PanAmSat to fund additional outlays of approximately $152 million in 1998 and
approximately $366 million in 1998. See "BUSINESS OF GALAXY--Sale-Leaseback
Arrangements." The ability of New PanAmSat to exercise such options and fund
its other capital programs and meet its debt obligations depends on the
success of New PanAmSat's business strategy, which is subject to uncertainties
and contingencies that will be beyond New PanAmSat's control.
 
  Litigation. On or about March 11, 1996, an action was commenced by Comsat
against PanAmSat, The News Corporation Limited ("News Corp.") and Televisa in
the United States District Court for the District of Maryland (the "Comsat
Litigation"). The complaint alleged that News Corp. wrongfully terminated an
agreement with Comsat for the use of transponders on an Intelsat satellite in
the amount of $261,240,000 over the term of a five-year agreement and breached
its alleged obligations under a tariff filed by Comsat with the FCC. As to
PanAmSat, the complaint alleged that PanAmSat, alone and in conspiracy with
others, interfered in a manner which would subject PanAmSat to liability with
the alleged contract and News Corp.'s alleged obligations under the tariff.
The complaint sought compensatory damages of $250 million and unspecified
punitive damages. On April 30, 1996, PanAmSat and the other defendants filed
motions to dismiss the complaint on numerous grounds, including lack of
personal jurisdiction. By order dated October 10, 1996, the District Court
dismissed the complaint without prejudice on the ground that the Court lacked
personal jurisdiction over all of
 
                                      40
<PAGE>
 
the defendants. On or about October 25, 1996, Comsat commenced a similar
action against PanAmSat, News Corp. and Televisa in the United States District
Court for the Central District of California. The complaint alleges that News
Corp. wrongfully terminated an agreement with Comsat for the lease of
transponders on an Intelsat satellite over the term of a five-year lease,
breached certain alleged promises related to such agreement and breached its
alleged obligations under a tariff filed by Comsat with the FCC. As to
PanAmSat, the complaint alleges that PanAmSat, alone and in conspiracy with
Televisa, intentionally interfered with the alleged agreement and with
Comsat's economic relationship with News Corp. The complaint in the present
action seeks actual and consequential damages, and punitive or exemplary
damages, in an amount to be determined at trial but which Comsat alleges
exceeds $50,000. On December 11, 1996, PanAmSat, News Corp. and Televisa filed
motions to dismiss the action on various grounds, including that the FCC has
primary jurisdiction over the dispute, that federal law preempts the claims
asserted against PanAmSat and Televisa, that the claims asserted against
Televisa and PanAmSat are not recognized by federal law, that such claims fail
to state a cause of action and that because such claims depend upon the
existence of enforceable rights under the tariff Comsat filed with the FCC,
the claims fail if the FCC determines that Comsat has no such rights. In this
regard, in April 1996, News Corp. filed a complaint with the FCC challenging
Comsat's tariff. Thereafter Comsat filed a motion with the FCC to hold that
proceeding in abeyance pending resolution of Comsat's civil suit. By letter
ruling dated December 6, 1996, the FCC denied Comsat's motion and established
a schedule to resolve the issues raised by News Corp.'s complaint. On January
27, 1997, the parties appeared before Judge Wardlaw for a hearing on the
motion to dismiss. From the bench, the Judge denied the motions to dismiss and
the parties have proceeded to discovery. PanAmSat believes the claims against
it are without merit and intends to vigorously contest any further prosecution
of these claims, although there can be no assurance that PanAmSat will
prevail.
 
  Uncertainties of Post-Merger Operations. The success of the Reorganization
and the related transactions will depend in part on the ability of New
PanAmSat to effectively integrate the businesses of PanAmSat and Galaxy.
PanAmSat's operations are primarily focused on international markets and
Galaxy's operations are primarily focused on North America. Although the
management of both companies believe that the operations of PanAmSat and
Galaxy will be complementary, there can be no assurance that the parties will
not encounter difficulties in merging the operations of PanAmSat with those of
Galaxy or that the benefits expected from the Reorganization will be realized.
The process of integrating the businesses of PanAmSat and Galaxy may also
require a disproportionate amount of time and attention of New PanAmSat's
management and financial and other resources of New PanAmSat. In addition,
integrating the two companies may be made more difficult initially by the
necessity of coordinating geographically separated organizations and
integrating personnel with disparate business backgrounds and corporate
cultures. As is typical in many business combinations, if PanAmSat and Galaxy
are not successful in integrating their corporate strategies and operations or
if their integrated operations fail to achieve market acceptance, their
combined business could be adversely affected.
 
  Effect of Loss of Key Personnel. The success of New PanAmSat's business will
depend in part upon the performance of Frederick A. Landman, President and
Chief Executive Officer, Carl A. Brown, Executive Vice President, and Lourdes
Saralegui, Executive Vice President, of New PanAmSat. The loss of such
executives could have an adverse effect on New PanAmSat's business. New
PanAmSat is not the beneficiary of any keyman life insurance policies for any
of Mr. Landman, Mr. Brown or Ms. Saralegui. See "THE REORGANIZATION--
Management and Operations of New PanAmSat and PanAmSat After the Merger."
 
  Control by the Principal Stockholder of New PanAmSat. Upon consummation of
the Reorganization, HCI will own at least a majority of the outstanding shares
of New PAS Common Stock. HCI will generally be able to control the vote on all
matters submitted to a vote of the holders of shares of outstanding New PAS
Common Stock, including election of New PanAmSat's directors, amendments to
New PanAmSat's Certificate of Incorporation and Bylaws and approval of
significant corporate transactions and other actions pertaining to New
PanAmSat which require approval of New PanAmSat's stockholders. Additionally,
HCI will be in a position to prevent a takeover of New PanAmSat by one or more
third parties, which could deprive New PanAmSat's minority stockholders of a
control premium that might otherwise be realized by them in connection with an
acquisition of New PanAmSat. See "OTHER AGREEMENTS--Stockholder Agreement."
 
                                      41
<PAGE>
 
  Potential Conflicts of Interest. After the Reorganization is consummated,
HCI may have significant on-going conflicts of interest between its ownership
of up to approximately 71.5% of New PAS Common Stock, its interests in
contracts to which its affiliates and New PanAmSat are parties and HCI's and
its affiliates' other interests in the communications industry. PanAmSat and
Galaxy have entered into material contracts and transactions with certain
affiliates of HCI, including satellite construction contracts and an agreement
for New PanAmSat to use three launch service opportunities. See "BUSINESS OF
PANAMSAT--Launch Arrangements," "BUSINESS OF GALAXY--Satellite Development and
Construction" and "--Launch Arrangements." New PanAmSat may enter into similar
contracts in the future. The Stockholder Agreement, however, provides that
agreements entered into between New PanAmSat and HCI or its affiliates must be
on terms no less favorable to New PanAmSat than those agreements ordinarily
entered into in comparable transactions by HCI or its relevant affiliate on an
arm's length basis with an unrelated party. In addition, a committee of the
New PanAmSat Board that is composed entirely of directors who are not current
or former employees of New PanAmSat or any of its affiliates must approve all
such agreements. With certain exceptions, pursuant to the Stockholder
Agreement, HCI and its affiliates may not compete with New PanAmSat in the
business presently conducted by Galaxy from the Closing Date until five years
after Closing. Nonetheless, HCI and certain of its affiliates have other
interests in the communications industry which may not coincide with New
PanAmSat's interests. For example, Hughes Network Systems sells satellite-
based business communications services on very small aperture terminals,
DIRECTV, Inc. ("DIRECTV") and DIRECTV International, Inc. ("DTVI") provide DTH
services and Hughes Satellite and Communications constructs satellites for
companies, which, in some cases, will compete directly with New PanAmSat. In
addition, HCI is developing a satellite business known as "SPACEWAY" for high
speed point-to-point transmission of voice, video, audio and data using Ka-
band frequencies ("SPACEWAY").
 
  Shares Eligible for Future Sale. Upon completion of the Reorganization, New
PanAmSat is expected to have an aggregate of 149,122,807 shares of New PAS
Common Stock outstanding, assuming that New PanAmSat does not issue more stock
than cash as consideration in the Merger and the Univisa Contribution. In
addition, up to 50,000,000 additional shares of New PAS Common Stock could be
issued in connection with the Merger and the Univisa Contribution if New
PanAmSat chooses, at its option, to issue additional shares of New PAS Common
Stock as consideration in the Univisa Contribution and the Merger to satisfy
elections by holders of PAS Class A Common Stock and PAS Ordinary Common Stock
and S Company to receive additional shares of such stock in lieu of cash
consideration. See "THE REORGANIZATION AGREEMENT--Elections by Holders of PAS
Common Stock; Exchange of Certificates in the Merger." The shares of New PAS
Common Stock that are paid as consideration in the Merger will be freely
tradable on the public market without restriction or further registration
under the Securities Act, except to the extent that such shares are held by a
person deemed to be an "affiliate" (as defined in the Securities Act) of New
PanAmSat or a person that would be deemed to have been an "affiliate" of
PanAmSat prior to the Merger, in which case such shares may be resold only in
transactions permitted by the resale provisions of Rule 145 under the
Securities Act or as otherwise permitted under the Securities Act. See "THE
REORGANIZATION--Federal Securities Laws Consequences." All of the other shares
of New PAS Common Stock issued in connection with the Merger, the Univisa
Contribution and the Asset Contribution will be "restricted securities" within
the meaning of Rule 144 promulgated under the Securities Act, but will be
eligible for public sale pursuant to Rule 144. New PanAmSat also may decide to
issue additional shares of New PAS Common Stock in the future. No predictions
can be made as to the effect, if any, that market sales of shares of New PAS
Common Stock, or the availability of shares for future sales, will have on the
market price of shares of New PAS Common Stock prevailing from time to time.
Sales of substantial amounts of New PAS Common Stock, or the perception that
such sales could occur, could adversely affect prevailing market prices for
New PAS Common Stock and could impair New PanAmSat's future ability to raise
capital through an offering of its equity securities. Neither PanAmSat nor
Galaxy currently anticipates that New PanAmSat will issue any shares of
preferred stock.
 
  Pursuant to the Stockholder Agreement, New PanAmSat, HCI, the Class A
Holders and S Company will be subject to certain restrictions on the sale of
their shares of New PAS Common Stock after the Closing Date. The parties to
the Stockholder Agreement are considering modifying the sale restrictions so
that the Class A Holders
 
                                      42
<PAGE>
 
and S Company would be permitted to sell a substantial portion of their shares
of New PanAmSat Common Stock during the first year after the Closing. See
"OTHER AGREEMENTS--Stockholder Agreement." In addition, concurrently with the
consummation of the Merger and the Univisa Contribution, HCI, S Company and
the Class A Holders will become parties to a Registration Rights Agreement
with New PanAmSat pursuant to which such parties will have the right, under
specific circumstances, to cause New PanAmSat to register their shares of New
PAS Common Stock under the Securities Act at the expense of New PanAmSat. See
"OTHER AGREEMENTS--Registration Rights Agreement."
 
  No Prior Public Market; Potential Volatility of Stock Price. Prior to the
Reorganization, there has been no public market for New PAS Common Stock. It
is anticipated that the New PAS Common Stock will be listed on the Nasdaq
under the symbol "SPOT" subject to official notice of issuance. However, there
can be no assurance that an active public market will develop or be sustained
after the Reorganization or that the price at which New PAS Common Stock will
trade in the public market subsequent to the Reorganization will correspond
with expectations. Further, the stock market may experience volatility that
affects the market prices of companies in ways unrelated to the operating
performance of such companies. These market fluctuations may adversely affect
the market price of New PAS Common Stock.
 
  No Dividends. PanAmSat and Galaxy anticipate that New PanAmSat will retain
future earnings for use in its business and does not anticipate paying any
dividends on New PAS Common Stock in the near future.

                              THE SPECIAL MEETING
 
SPECIAL MEETING
 
  This Proxy Statement/Prospectus is being furnished to PanAmSat stockholders
in connection with the solicitation by the PanAmSat Board of proxies for use
at the Special Meeting to be held on Thursday, May 8, 1997 at 11:00 a.m. local
time at the Equinox Hotel, Historic Route 7A, Manchester Village, Vermont.
 
  At the Special Meeting, PanAmSat stockholders will consider and vote upon
the following proposals: (a) the approval and adoption of the Reorganization
Agreement and the Merger Agreement and (b) the approval and adoption of the
Charter Amendment. See "PROPOSAL TO APPROVE AND ADOPT THE CHARTER AMENDMENT."
 
  THE PANAMSAT BOARD HAS APPROVED THE REORGANIZATION AGREEMENT AND THE MERGER
AGREEMENT AND HAS DEEMED ADVISABLE AND APPROVED THE CHARTER AMENDMENT AND
RECOMMENDS THAT PANAMSAT STOCKHOLDERS VOTE "FOR" APPROVAL AND ADOPTION OF THE
REORGANIZATION AGREEMENT AND THE MERGER AGREEMENT AND "FOR" APPROVAL AND
ADOPTION OF THE CHARTER AMENDMENT. See "THE REORGANIZATION--Recommendation of
the PanAmSat Board and Reasons for the Merger." The Reorganization Agreement
has been approved by all of the required Hughes Parties.
 
  This Proxy Statement/Prospectus also contains certain information concerning
the sale by PanAmSat of the DTH Options. The PanAmSat Board has determined
that the sale of the DTH Options is fair to and in the best interests of
PanAmSat and its stockholders and has approved such sale. No stockholder
approval is required or sought in connection with such sale. See "THE
REORGANIZATION--Background of the Reorganization," "THE REORGANIZATION
AGREEMENT--Conditions to the Reorganization" and "THE DTH SALE."
 
RECORD DATE; SHARES ENTITLED TO VOTE; VOTE REQUIRED
 
  The close of business on April 8, 1997 has been fixed as the Record Date for
determining the holders of PAS Common Stock who are entitled to notice of and
to vote at the Special Meeting. As of the Record Date, there were 100,011,620
shares of PAS Common Stock outstanding of which 21,231,415 shares consisted of
PAS Class A Common Stock, 40,459,431 shares consisted of PAS Class B Common
Stock and 38,320,774 shares consisted of PAS Ordinary Common Stock outstanding
and entitled to vote. The holders of record on the Record Date of shares of
PAS Class A Common Stock and PAS Class B Common Stock are entitled to 15 votes
per share of PAS Class A Common Stock and PAS Class B Common Stock, as the
case may be, on each matter submitted to a vote at the Special Meeting. As of
the Record Date, the directors, executive officers and affiliates of PanAmSat
owned approximately 81% of the outstanding shares of PAS Common Stock. The
holders of record of shares of PAS Ordinary Common Stock are entitled to one
vote per share of PAS Ordinary Common Stock on each matter submitted to a vote
at the Special Meeting. The presence in person or by proxy of the holders of
record of a majority of the votes of the outstanding shares entitled to vote
is necessary to constitute a quorum for the transaction of business at the
Special Meeting. The affirmative vote of (i) the holders of a majority of the
votes of the outstanding shares of PAS Class A Common Stock and PAS Ordinary
Common Stock, voting together as a single class, and the holders of a majority
of the outstanding shares of PAS Class B Common Stock and PAS Ordinary Common
Stock, voting together as a single class, as well as (ii) the holders of a
majority of the votes of the outstanding shares of PAS Class A Common Stock
(as long as the outstanding shares of PAS Class A Common Stock represent at
least 5% of the total outstanding shares of PAS Common Stock) and a majority
of the votes of the outstanding shares of PAS Class B Common Stock (as long as
the outstanding shares of PAS Class B Common Stock represent at least 5% of
the total outstanding shares of PAS Common Stock), is necessary to approve the
Reorganization Agreement, the Merger Agreement and the Charter Amendment. In
addition, the affirmative vote of the holders of the majority of votes of the
outstanding shares of PAS Class A Common Stock, PAS Class B Common Stock and
PAS Ordinary Common Stock, each voting as a separate class, is necessary to
approve the Charter Amendment.
 
 
                                      44
<PAGE>
 
  Pursuant to the Principal Stockholders Agreement, the Class A Holders and
Class B Holder have agreed to vote all of their shares of PAS Common Stock in
favor of the Reorganization Agreement and the Merger Agreement and to take any
actions required in furtherance thereof. In connection therewith, immediately
before the Record Date, the Class A Holders voluntarily converted the number
of shares of PAS Class A Common Stock necessary to constitute a majority of
the outstanding PAS Ordinary Common Stock from PAS Class A Common Stock into
PAS Ordinary Common Stock. On the Record Date, the beneficial owners of all of
the outstanding shares of PAS Class A Common Stock, PAS Class B Common Stock
and the Converted Shares held the voting power required to approve the
Reorganization Agreement, the Merger Agreement and the Charter Amendment.
Accordingly, approval thereof by the PanAmSat stockholders is assured.
 
PROXIES; PROXY SOLICITATION
 
  Shares of PAS Common Stock represented by properly executed proxies at or
prior to the Special Meeting which have not been revoked will be voted at the
Special Meeting in accordance with the instructions contained therein. Shares
of PAS Common Stock represented by properly executed proxies for which no
instruction is given will be voted "FOR" approval and adoption of the
Reorganization Agreement and the Merger Agreement and "FOR" approval and
adoption of the Charter Amendment. PanAmSat stockholders are requested to
complete, sign, date and return promptly the enclosed proxy card in the
postage prepaid envelope provided for this purpose to ensure that their shares
are voted. A stockholder may revoke a proxy by submitting, at any time prior
to the vote on the Reorganization Agreement, the Merger Agreement and the
Charter Amendment, a later-dated proxy with respect to the same shares, by
delivering written notice of revocation to the Secretary of PanAmSat at any
time prior to such vote or by attending the Special Meeting and voting in
person. Mere attendance at the Special Meeting will not in and of itself
revoke a proxy.
 
  If the Special Meeting is postponed or adjourned for any reason, at any
subsequent reconvening of the Special Meeting all proxies will be voted in the
same manner as such proxies would have been voted at the original convening of
the meeting (except for any proxies which have theretofore effectively been
revoked or withdrawn), notwithstanding that they may have been effectively
voted on the same or any other matter at a previous meeting. Abstentions and
broker non-votes will have the effect of a vote against the approval of the
Reorganization Agreement, the Merger Agreement and the Charter Amendment.
PanAmSat's Board knows of no other matter that will be presented for action at
the PanAmSat Special Meeting. If, however, any other matter properly comes
before the PanAmSat Special Meeting, the persons named in the proxy or their
substitutes will vote thereon in accordance with their best judgment.
 
  PanAmSat will bear the cost of soliciting proxies from its stockholders. In
addition to solicitation by mail, directors, officers and employees of
PanAmSat may solicit proxies by telephone, telegram or otherwise. Such
directors, officers and employees of PanAmSat will not be additionally
compensated for such solicitation but may be reimbursed for out-of-pocket
expenses incurred in connection therewith. Brokerage firms, fiduciaries and
other custodians who forward soliciting material to the beneficial owners of
shares of PAS Common Stock held of record by them will be reimbursed for their
reasonable expenses incurred in forwarding such material.

                                 THE COMPANIES
 
PANAMSAT
 
  PanAmSat operates the world's first privately owned global (excluding
domestic U.S.) satellite communications system and currently owns and operates
four satellites serving Latin America, the Caribbean, Europe, Asia, the Middle
East and Africa. PanAmSat currently provides satellite services primarily to
the broadcasting and business communications markets and also provides
services to the long-distance telephony market. In connection with its current
services, PanAmSat is pursuing international opportunities in the satellite
DTH television market. PanAmSat plans to launch additional satellites in the
future to meet anticipated increases in customer demand and currently has four
satellites under construction.
 
  PanAmSat's first satellite, PAS-1, was launched in 1988 for service over the
Atlantic Ocean Region and is a leading satellite for television and cable
programming distribution in Latin America. PanAmSat's second satellite, PAS-2,
was launched in July 1994 for service over the Pacific Ocean Region and is a
leading satellite for programming distribution in the Asia-Pacific region.
PanAmSat's PAS-4 satellite was launched in August 1995 for service over the
Indian Ocean Region and is a leading satellite for programming distribution in
south Asia and Africa. PanAmSat's PAS-3 satellite was launched on January 12,
1996 for service over the Atlantic Ocean Region. PAS-3 and PAS-1 are the
leading satellites for television and cable programming distribution in Latin
America. PanAmSat expects to launch two additional satellites to serve the
Atlantic Ocean Region: PAS-6 in May 1997; and PAS-5 in July 1997. However,
SS/Loral has recently informed PanAmSat of circumstances that could result in
a delay in the launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess
Weight." PanAmSat intends to launch PAS-7 and PAS-8 in early 1998, which are
expected to serve the Indian Ocean Region and the Pacific Ocean Region,
respectively. PanAmSat expects that in the future it will launch additional
satellites to meet then-anticipated customer demand. There can be no
assurance, however, that the schedule for PanAmSat's future satellite launches
will be met.
 
GALAXY
 
  Galaxy is a leading provider of commercial satellite services in the United
States. Galaxy offers satellite transponder capacity to cable television
programmers, broadcast television programmers, business communications
customers and DTH service providers for video, audio and data communications
applications. Galaxy operates a fleet of ten commercial geostationary fixed
service satellites, nine of which primarily serve the United States and one of
which serves both the United States and Latin America. Galaxy also provides
satellite TT&C services for its own satellite fleet as well as for other
satellites owned by DIRECTV, PanAmSat and American Mobile Satellite
Corporation.
 
  Galaxy was established by HE in 1979 and launched its first satellite in
1983. Galaxy's expansion of service to customers in the United States was
accelerated by the acquisitions of the three-satellite Westar C-band system in
1989 and the three-satellite SBS Ku-band system in 1990. Today, in addition to
Galaxy's fleet of ten commercial satellites, Galaxy has two satellites under
construction (Galaxy VIII-i and Galaxy X) and three additional satellites in
various stages of development (Galaxy XI, Galaxy XIII-i and Galaxy XIV-i)
which are expected to provide new and replacement transponder capacity for
satellite customers. Subject to regulatory approvals, Galaxy expects to launch
these five satellites by 2000. There can be no assurance, however, that
regulatory approvals will be obtained or that the schedule for Galaxy's future
satellite launches will be met.
 
NEW PANAMSAT
 
  New PanAmSat, a wholly owned subsidiary of HCI, has not conducted any
substantial business activities to date, other than those incident to its
formation, its execution of the Reorganization Agreement and related
agreements and its participation in the preparation of this Proxy
Statement/Prospectus. Immediately following the consummation of the Merger,
New PanAmSat will own and operate Galaxy and become a holding company for
PanAmSat and its subsidiaries. Accordingly, the business of New PanAmSat,
operated directly and through its wholly owned subsidiary, will be the
businesses currently conducted by PanAmSat and Galaxy. See "BUSINESS OF NEW
PANAMSAT," "BUSINESS OF PANAMSAT" and "BUSINESS OF GALAXY."
 
PAS MERGER CORP.
 
  PAS Merger Corp., a Delaware corporation and wholly owned subsidiary of New
PanAmSat, was formed by New PanAmSat solely for the purpose of effecting the
Merger.

                              THE REORGANIZATION
 
BACKGROUND OF THE REORGANIZATION
 
  In late January 1996, Mrs. Mary Anselmo, the majority beneficial owner of
the PAS Class A Common Stock, and Mr. Emilio Azcarraga, the Chairman of
Televisa, the beneficial owner of all of the PAS Class B Common Stock, agreed
to explore options for achieving liquidity with respect to their respective
stock positions in PanAmSat.
 
  The two stockholders accordingly instructed management of PanAmSat to
explore options that would allow the stockholders to achieve their strategic
objectives, and management conducted discussions with PanAmSat's financial
advisor, Morgan Stanley, and PanAmSat's lawyers, Chadbourne & Parke LLP, in
order to determine how the respective goals of the holders of the PAS Class A
Common Stock and the holder of the PAS Class B Common Stock could be achieved
in a manner that would ensure equal treatment for all holders of PAS Common
Stock. Televisa's representatives stated that a condition to any transaction
would be that the transaction be structured in a tax efficient manner from
Televisa's perspective.
 
  On February 15, 1996, the PanAmSat Board met to discuss the options
available to PanAmSat, including the possibility of conducting an auction for
the sale of PanAmSat, a search for a strategic buyer or buyers, a secondary
sale of stock to the public or some combination of the foregoing. The PanAmSat
Board also authorized management to design and implement retention
arrangements for the officers and employees of PanAmSat.
 
  On March 21, 1996 the PanAmSat Board held a special meeting at which it
formally agreed to engage Morgan Stanley to act as financial advisor to
PanAmSat to explore strategic alternatives, including joint ventures,
alliances, mergers or the sale of PanAmSat. Over the next few weeks management
worked with Morgan Stanley to refine the methodology for a corporate
transaction and with Chadbourne & Parke LLP to evaluate certain employee and
officer retention issues. The PanAmSat Board discussed with its legal and
financial advisors the desirability of proceeding both with a secondary
offering for the sale of shares of PAS Class A Common Stock and PAS Class B
Common Stock and an exploration of strategic alternatives. In connection with
the former, the PanAmSat Board authorized the filing of a secondary offering
with the Commission at or before the time that PanAmSat announced its
intention to seek a business combination or sale of its stock in order to
permit PanAmSat to proceed quickly with an offering and provide liquidity to
the holders of the PAS Class A Common Stock and the PAS Class B Common Stock
if a business combination or strategic alliance did not materialize. The
PanAmSat Board also authorized Morgan Stanley to approach a select group of
companies to gauge their level of interest in a transaction involving
PanAmSat. At the March 21, 1996 meeting, the PanAmSat Board also authorized
the engagement of William M. Mercer, Incorporated ("Mercer") to advise
PanAmSat with respect to employee retention arrangements that would be
comparable to those at similar companies.
 
  On April 2, 1996, PanAmSat publicly announced that it was exploring
alternatives to enable its stockholders to meet their financial objectives and
in connection therewith filed a registration statement with the Commission for
an underwritten secondary offering of PAS Common Stock anticipated to be in
the amount of approximately $350 million.
 
  On the day of the public announcement, pursuant to PanAmSat's instructions,
Morgan Stanley called a number of potentially interested parties, including
HE, to solicit interest in a transaction involving PanAmSat. Over the course
of the following weeks, confidentiality agreements with various interested
parties were executed and information requests were made of and responded to
by PanAmSat. HE signed its confidentiality agreement on April 10, 1996 and
commenced its information requests the next day, which requests were responded
to by PanAmSat on April 13, 16, 19 and 22.
 
  On April 18, 1996, Morgan Stanley forwarded to the various interested
parties a letter outlining the procedures for written preliminary indications
of interest and a copy of the draft merger agreement proposed by PanAmSat.
Over the next two to three weeks, the interested parties responded with
preliminary indications of
 
                                      47
<PAGE>
 
interest to Morgan Stanley, and on May 3, 1996, HE submitted its preliminary
indication of interest to Morgan Stanley.
 
  Pursuant to PanAmSat's instructions, Morgan Stanley notified certain of the
interested parties of their selection to proceed to the due diligence phase of
the process in the following week and a number of the interested parties and
their representatives, including HE and its representatives, met at the
offices of Chadbourne & Parke LLP in New York City over the following month to
attend management presentations, if requested, to review certain documents of
PanAmSat made available in a due diligence room and to discuss with PanAmSat
and its representatives follow-up questions with respect to the management
presentations and the due diligence materials.
 
  During the week beginning June 7, 1996, Morgan Stanley met with various
interested parties to discuss the preliminary indications of interest, the
sale process and the related timetable, and on June 13, 1996, Morgan Stanley
sent out a letter to interested parties, including HE, outlining the
procedures for a firm written offer for PanAmSat.
 
  On June 25, 1996, HE submitted to Morgan Stanley a proposal to combine
Galaxy with PanAmSat in a 100% stock transaction. Morgan Stanley also received
bids from other interested parties that were not all stock bids. Since
PanAmSat and the holders of the PAS Class A Common Stock and PAS Class B
Common Stock deemed an all stock bid unsatisfactory, representatives of
PanAmSat and its management commenced discussions with other of the interested
parties and indicated to HE that an all stock bid was not satisfactory.
 
  On July 19, 1996, HE submitted a revised proposal to Morgan Stanley wherein
HE proposed to combine Galaxy with PanAmSat in a half cash, half stock
transaction. The HE proposal involved stock in a new venture that would
include Galaxy and contained as a condition to the transaction that PanAmSat
divest the DTH Options. PanAmSat's representatives and advisors met with HE's
representatives and advisors at HCI's offices in Long Beach, California to
conduct preliminary due diligence on Galaxy intermittently during the period
of July 20, 1996 to August 1, 1996. As PanAmSat was not satisfied with the
proposed structure, which involved leaving PanAmSat as a public holding
company with an interest in a new joint venture company into which both
parties would place their geostationary satellite businesses, a meeting was
held in Darien, Connecticut on July 26, 1996, among C. Michael Armstrong,
Chairman and Chief Executive Officer of HE, Charles H. Noski, Senior Vice
President and Chief Financial Officer of HE, Kenneth N. Heintz, Vice President
Corporate Development of HE, Carl A. Brown, Senior Vice President, Galaxy
Satellite Services of HCI, Frederick A. Landman, Patrick J. Costello and James
W. Cuminale of PanAmSat and representatives of the Anselmo family, together
with representatives of Morgan Stanley, Greenhill & Co. and Donaldson, Lufkin
& Jenrette Securities Corporation, the latter two also acting as advisors to
HE, and Lawrence W. Dam and Guillermo Canedo White (by telephone) of Televisa
to discuss the proposed transaction structure. The foregoing meetings and
discussions were followed with meetings in New York on August 6, 7, and 8,
1996, with all representatives and advisors, for the purpose of discussing
alternate structures that would achieve the parties' objectives. At the end of
such meetings, the parties agreed on a structure that closely approximated the
structure ultimately used in the transaction. Each of the earlier proposals
received between July 19, 1996 and August 14, 1996 contained ranges of stated
notional valuations of PanAmSat, which in some cases were higher than the
final proposal ultimately agreed to by the parties. However, none of the
earlier proposals contained a cash component and all involved an assumed
valuation for the Galaxy Business which varied from the actual valuation. At
the direction of the holders of PAS Class A Common Stock and PAS Class B
Common Stock, PanAmSat required that bids be comprised of cash. PanAmSat and
its advisors conducted negotiations with the goal of obtaining the highest
value for PanAmSat's stockholders.
 
  On August 14, 1996, PanAmSat and representatives of the Anselmo family and
the PAS Class B Common Stock and counsel to and representatives of Televisa
met at Morgan Stanley's offices in New York City to review the status of the
transaction. This meeting was followed immediately by a meeting between the
principal executive officers of PanAmSat and HE, their representatives and
advisors, and a representative of the Anselmo family to discuss the exact
percentages of the new company that each side would hold at the end of the
 
                                      48
<PAGE>
 
transaction. This meeting ended inconclusively but was followed by an
additional meeting on August 15, 1996 at which the parties agreed on a
structure and the percentage split that ultimately formed the basis for the
transaction: New PanAmSat would acquire Galaxy and would offer $1.5 billion in
cash and an additional amount of stock in New PanAmSat to the stockholders of
PanAmSat in a combination or merger with a subsidiary of New PanAmSat.
Assuming that all of the available cash was used in the merger, following the
transaction HE would hold 72% and the former stockholders of PanAmSat would
hold 28% of New PanAmSat. HE indicated that, following the Closing, it would
consider causing New PanAmSat to sell shares in an offering in an aggregate
amount equal to $1.5 billion (assuming a $30 per share offering price for New
PanAmSat stock, HE would hold approximately 52.5% of New PanAmSat, and the
public, together with the former stockholders of PanAmSat, would hold the
remainder). At the August 15, 1996 meeting the parties also agreed on all of
the other principal points of the transaction, subject to the negotiation and
execution of definitive agreements and approval of the parties' respective
Boards.
 
  From August 20 to 26, 1996, PanAmSat's representatives and advisors met with
HE's representatives and advisors at HCI's facility in Long Beach, California
to continue due diligence on Galaxy. From August 26 to 29, 1996, HE
representatives and advisors met with PanAmSat representatives and advisors at
Chadbourne & Parke LLP in New York City to perform confirmatory due diligence.
Latham & Watkins, counsel to HE, also sent out a first draft of the proposed
Reorganization Agreement at this time and the parties held preliminary
discussions at the offices of Chadbourne & Parke LLP on major points of
understanding that would form the basis for the initial negotiation on the
documents. This was followed by a day of negotiations at Latham & Watkins'
offices in Los Angeles on September 4, 1996.
 
  In mid-August 1996, the members of the DTH Committee of the PanAmSat Board
(comprised of three directors unaffiliated with Televisa) determined that it
was desirable to engage Salomon Brothers to represent PanAmSat in connection
with the sale of the DTH Options. The DTH Committee believed that, given that
the interest of PanAmSat in the DTH Options is held derivatively through
Televisa, Televisa-controlled entities would be equity participants in the
joint ventures to which the DTH Options applied and the interests in the DTH
Options were subject to certain prohibitions on transfers, Televisa would be
the most logical party to purchase the DTH Options. Accordingly, over this
time period representatives of the two companies, including Frederick A.
Landman and Guillermo Canedo White (who is also a member of the PanAmSat
Board), had discussions to establish a price for this asset. The parties
agreed on a purchase price of $225 million in shares of New PAS Common Stock
assuming a valuation of $30 per share of New PAS Common Stock. Since Televisa
required that the purchase be made with stock of New PanAmSat and the 1993
Indentures (as defined below) require that PanAmSat receive at least 85% in
cash in connection with certain sales of assets, the parties agreed on the
structure ultimately adopted: a share repurchase by New PanAmSat of 7.5
million shares of the New PAS Common Stock received by S Company pursuant to
the Univisa Contribution for $225 million, followed by a purchase of the DTH
Options by either Televisa, S Company and/or their designees for $225 million.
See "THE DTH SALE."
 
  The parties reconvened at the offices of Chadbourne & Parke LLP in New York
from September 11 to 19, 1996, to conclude the negotiation and drafting of the
definitive agreements, which ultimately provided, among other things, that if
all of the available cash was used in the merger following the transaction HE
would indirectly hold 71.5%, and the former stockholders of PanAmSat would
hold 28.5%, of New PanAmSat. At various times during the months preceding the
announcement of the transaction, PanAmSat's Common Stock traded above $30 per
share. During the negotiations, PanAmSat and its advisors focused primarily on
obtaining the highest value for PanAmSat's stockholders.
 
  On September 19, 1996, the PanAmSat Board met to consider the final terms of
the proposed Reorganization. After a detailed discussion of the consideration
in the aggregate to be received by the holders of the PAS Common Stock
pursuant to the Merger and the Univisa Contribution, the consideration to be
received by PanAmSat for the DTH Options, the consideration to be paid in the
Share Repurchase and other legal, accounting and financial issues, the
PanAmSat Board received the opinion of Morgan Stanley that the consideration
in the aggregate to be received by the holders of the PAS Common Stock
pursuant to the Merger and the Univisa Contribution is fair to such holders
from a financial point of view. See "THE
 
                                      49
<PAGE>
 
REORGANIZATION--Opinion of PanAmSat's Financial Advisor." The PanAmSat Board
also received the opinion of Salomon Brothers that the consideration to be
received by PanAmSat for the DTH Options represented fair value for the DTH
Options from a financial point of view. See "THE DTH SALE--Opinion of
PanAmSat's Financial Advisor Regarding the DTH Sale." The PanAmSat Board then
determined that the Reorganization, upon the terms and conditions set forth in
the Reorganization Agreement, is fair to, and in the best interests of, the
stockholders of PanAmSat and unanimously approved and adopted the
Reorganization Agreement and the Merger and resolved to recommend to the
stockholders of PanAmSat that they vote to approve the Reorganization
Agreement, the Merger and the transactions contemplated thereby. The parties
signed the definitive agreements on September 20, 1996 and issued a press
release announcing the Reorganization and the related transactions the same
day.
 
  On April 4, 1997, the parties entered into an Amendment to the
Reorganization Agreement pursuant to which they agreed to amend the
Reorganization Agreement and the forms of Stockholder Agreement and
Registration Rights Agreement to be entered into at the Closing to, among
other things, (i) reflect the voluntary conversion by the holders of PAS Class
A Common Stock to PAS Ordinary Common Stock immediately prior to the Record
Date and (ii) clarify certain other provisions.
 
RECOMMENDATION OF THE PANAMSAT BOARD AND REASONS FOR THE MERGER
 
  In considering the recommendations of the PanAmSat Board with respect to the
Reorganization Agreement, the Merger Agreement and the transactions
contemplated thereby, PanAmSat's stockholders should be aware that certain
members of PanAmSat's management, the PanAmSat Board and the Principal
Stockholders have certain interests in the Reorganization that are different
from and in addition to their duties as directors and officers of PanAmSat.
See "THE REORGANIZATION--Interests of Certain Persons in the Reorganization."
 
  The PanAmSat Board believes that the terms of the Reorganization are fair
to, and in the best interests of, PanAmSat and its stockholders. Accordingly,
the PanAmSat Board, by a unanimous vote of those directors present, has
approved the Reorganization Agreement and the Merger Agreement and recommends
their adoption by the holders of PAS Common Stock. The PanAmSat Board believes
that the Reorganization represents a unique opportunity. The Reorganization
will result in shareholder liquidity for PanAmSat stockholders, each of whom
will have the opportunity to receive a minimum of $15 in cash for each of
their shares. For the holders of shares of PAS Class A Common Stock and S
Company, the indirect holder of PAS Class B Common Stock, which represent more
than 80% of the outstanding shares of PAS Common Stock, the Reorganization
provides an alternative to obtaining cash for shares in a public offering. The
Reorganization will result in the combination of PanAmSat and Galaxy, two
premiere satellite service companies with complementary businesses, and
provide unusual opportunities for those PanAmSat stockholders who elect to
take stock in the combined enterprise to participate in its growth. This
growth will derive from operating efficiencies obtained from: economies of
scale; the ability to provide one point of contact for global satellite
services in one company; improved opportunities for cost reductions;
geographic market diversification, which reduces risk and affords unusual
growth opportunities; the ability to provide domestic and international
satellite coverage; and the long-term financial capability of a larger
company. In the judgment of the PanAmSat Board, these factors combine to offer
stockholders improved opportunities for earnings.
 
  In reaching this conclusion, the PanAmSat Board considered: (i) the
prospective financial strength of each company individually and the benefits
of the combination discussed above; (ii) current industry, economic and market
conditions which encourage consolidation to reduce risk and create new avenues
for earnings growth; (iii) the proposed structure of the transaction between
PanAmSat and Galaxy and the terms of the Reorganization Agreement and other
documents to be executed in connection with the Reorganization, which provide
for reciprocal representations and warranties, conditions to closing and
rights to termination, and balanced rights and obligations; and (iv) the
opinion of Morgan Stanley to the effect that the consideration in the
aggregate to be received by the holders of shares of PAS Common Stock in
connection with the Merger and the Univisa Contribution, is fair from a
financial point of view to such holders. See "--Opinion of PanAmSat's
Financial Advisor" below and Appendix D. In determining that the Merger is
fair to and in the best interests of its stockholders, the PanAmSat Board
considered the above facts as a whole and did not assign specific or relative
weights to them.

  THE PANAMSAT BOARD HAS APPROVED THE REORGANIZATION AGREEMENT, THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY AND BELIEVES THAT THE
TERMS OF THE MERGER ARE FAIR TO, AND IN THE BEST INTEREST OF, PANAMSAT'S
STOCKHOLDERS. THE PANAMSAT BOARD ALSO HAS DEEMED ADVISABLE AND APPROVED THE
CHARTER AMENDMENT. THE PANAMSAT BOARD RECOMMENDS A VOTE "FOR" APPROVAL OF THE
REORGANIZATION AGREEMENT AND THE MERGER AGREEMENT AND A VOTE "FOR" APPROVAL OF
THE CHARTER AMENDMENT.
 
OPINION OF PANAMSAT'S FINANCIAL ADVISOR
 
  In March 1996, PanAmSat retained Morgan Stanley to act as its financial
advisor in connection with a proposed sale or business combination involving
PanAmSat.
 
  At the September 19, 1996 meeting of the PanAmSat Board, Morgan Stanley
rendered its oral opinion that, as of such date and subject to the various
considerations to be set forth in its written opinion, the consideration in
the aggregate to be received by the holders of shares of PAS Common Stock, in
connection with the Merger and the Univisa Contribution, is fair from a
financial point of view to such holders. Morgan Stanley subsequently delivered
to the PanAmSat Board a written opinion dated September 20, 1996 confirming
such oral opinion and containing its additional opinion that the consideration
to be paid in the Share Repurchase is fair from a financial point of view to
New PanAmSat. Morgan Stanley subsequently confirmed its September 20, 1996
opinion by delivery of a written opinion dated as of the date of this Proxy
Statement/Prospectus (the "Morgan Stanley Opinion").
 
  THE FULL TEXT OF THE MORGAN STANLEY OPINION WHICH SETS FORTH, AMONG OTHER
THINGS, ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED, AND
LIMITATIONS ON THE REVIEW UNDERTAKEN BY MORGAN STANLEY, IS ATTACHED AS
APPENDIX D TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY
REFERENCE. THE MORGAN STANLEY OPINION IS DIRECTED TO THE PANAMSAT BOARD AND
ADDRESSES ONLY THE FAIRNESS OF THE CONSIDERATION IN THE AGGREGATE TO BE
RECEIVED BY THE HOLDERS OF SHARES OF PAS COMMON STOCK, IN CONNECTION WITH THE
MERGER AND THE UNIVISA CONTRIBUTION, FROM A FINANCIAL POINT OF VIEW AND THE
FAIRNESS OF THE CONSIDERATION TO BE PAID BY NEW PANAMSAT IN THE SHARE
REPURCHASE FROM A FINANCIAL POINT OF VIEW. IT DOES NOT ADDRESS ANY OTHER
ASPECT OF THE REORGANIZATION AND DOES NOT CONSTITUTE AN OPINION OR A
RECOMMENDATION AS TO HOW ANY HOLDERS OF SHARES OF PAS COMMON STOCK SHOULD VOTE
AT THE SPECIAL MEETING OR WHETHER SUCH HOLDERS SHOULD ELECT TO RECEIVE THE
STANDARD CONSIDERATION, THE STOCK CONSIDERATION OR THE STANDARD CASH
CONSIDERATION (AS SUCH TERMS ARE DEFINED BELOW). IN ADDITION, THE MORGAN
STANLEY OPINION DOES NOT IN ANY MANNER ADDRESS THE PRICES AT WHICH THE SHARES
OF NEW PAS COMMON STOCK WILL TRADE FOLLOWING CONSUMMATION OF THE
REORGANIZATION. THE SUMMARY OF THE MORGAN STANLEY OPINION SET FORTH IN THIS
PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
FULL TEXT OF SUCH OPINION. THE HOLDERS OF SHARES OF PAS COMMON STOCK ARE URGED
TO READ THE MORGAN STANLEY OPINION IN ITS ENTIRETY.
 
  In arriving at its opinion, Morgan Stanley, among other things: (i) analyzed
certain publicly available financial statements of PanAmSat and other publicly
available information relating to PanAmSat and Galaxy; (ii) analyzed certain
internal financial statements and other financial and operating data
concerning PanAmSat and Galaxy prepared by the respective managements of
PanAmSat and HCI and discussed certain of this data with senior executives of
PanAmSat and HCI; (iii) analyzed certain financial projections of PanAmSat and
Galaxy prepared by the respective managements of PanAmSat and HCI; (iv)
discussed the past and current operations and financial condition and the
prospects of PanAmSat and Galaxy with senior executives of PanAmSat and HCI,
respectively; (v) reviewed the reported prices and trading activity for PAS
Common Stock; (vi) analyzed the estimated pro forma impact of the Merger, the
Univisa Contribution and the Asset Contribution on New PanAmSat's financial
ratios; (vii) reviewed and considered the financial and other information
prepared by members of senior management of PanAmSat and HCI relating to the
relative contributions of PanAmSat and Galaxy to New PanAmSat; (viii)
participated in discussions and negotiations among representatives of
PanAmSat, HCI and certain other parties and their financial and legal
advisors; (ix) reviewed the Reorganization Agreement, the Univisa Contribution
Agreement and certain related documents; and (x) performed such other analyses
as Morgan Stanley deemed appropriate.
 
                                      51
<PAGE>
 
  In rendering its opinion, Morgan Stanley assumed and relied upon, without
independent verification, the accuracy and completeness of the information
reviewed by Morgan Stanley for purposes of its opinion. Morgan Stanley assumed
that the financial projections of PanAmSat and Galaxy were reasonably prepared
on bases reflecting the best currently available estimates and judgments of
the future financial performance of PanAmSat and Galaxy, respectively. Morgan
Stanley did not make any independent valuation or appraisal of the assets or
liabilities of PanAmSat or Galaxy, nor was it furnished with any such
appraisals. The Morgan Stanley Opinion is necessarily based on economic,
market and other conditions as in effect on, and the information made
available to it as of, the date of its opinion. Morgan Stanley assumed that
the Merger, the Univisa Contribution and the Asset Contribution and the Share
Repurchase will be consummated in accordance with the terms set forth in the
Reorganization Agreement, the Univisa Contribution Agreement and certain
related agreements. In addition, Morgan Stanley assumed that the Merger, the
Univisa Contribution and the Asset Contribution together will be treated as a
tax-free exchange, pursuant to the Code (as defined below). Morgan Stanley
also assumed that in connection with the receipt of all necessary regulatory
approvals for the Merger, the Univisa Contribution and the Asset Contribution,
no restrictions will be imposed that would have a material adverse effect on
the contemplated benefits expected to be derived in the proposed Merger, the
Univisa Contribution and the Asset Contribution.
 
  The following is a brief summary of certain analyses performed by Morgan
Stanley and reviewed with the PanAmSat Board in connection with its opinions
to the PanAmSat Board.
 
  PAS Common Stock Performance. Morgan Stanley's analysis of the performance
of the PAS Common Stock consisted of a historical analysis of closing prices
and trading volumes from the date of PanAmSat's IPO on September 21, 1995 to
September 16, 1996. During this period, PAS Common Stock, since its IPO price
of $17, achieved a high of $33.25 and a low of $14, based on closing prices.
PAS Common Stock closed at a price of $28 on September 16, 1996.
 
  Transaction Consideration Analysis. Morgan Stanley noted that, based on the
financial projections of New PanAmSat as of June 30, 1997 and assuming that
New PanAmSat pays half stock and half cash as consideration in the Merger and
the Univisa Contribution, the consideration to be received by S Company and
the holders of shares of PAS Class A Common Stock and PAS Ordinary Common
Stock--i.e., 28.50% of New PanAmSat (following consummation of the sale of the
DTH Options and Share Repurchase) plus the Standard Cash Consideration (as
defined below) of $1.5 billion--is between $29.25 and $31.50 for each
outstanding share of PAS Common Stock. Morgan Stanley observed that this range
of consideration to be received represents a 35.7% to 41.4% internal rate of
return as compared to the IPO price of $17 on September 21, 1995, a 51.1% to
57.3% internal rate of return to the historical low close of $14 on October 9,
1995, and a (6.2%) to (2.7%) internal rate of return to the historical high
close of $33.25 on April 30, 1996.
 
  Discounted Cash Flow Analysis. Morgan Stanley conducted a discounted cash
flow analysis of PanAmSat and Galaxy for the fiscal years ended 1997 through
2003 to estimate the present value of the stand-alone unlevered free cash
flows that PanAmSat and Galaxy are expected to generate if PanAmSat and Galaxy
perform in accordance with scenarios based upon certain financial forecasts.
The discounted cash flow analysis for PanAmSat and Galaxy was based upon
certain discussions with the senior management of PanAmSat and HCI as well as
upon certain financial forecasts prepared by the management of PanAmSat and
HCI. Unlevered free cash flows of PanAmSat and Galaxy were calculated as net
income plus depreciation and amortization plus deferred taxes plus other
noncash expenses plus after-tax net interest expense less noncash revenues
less capital expenditures less investment in working capital.
 
  Morgan Stanley calculated terminal values for PanAmSat by applying a 7%
perpetual growth rate, valued as of June 30, 1997, to the unlevered free cash
flow in fiscal 2003, representing an estimated long-term cash flow growth rate
for PanAmSat. The unlevered free cash flow streams and terminal values for
PanAmSat were then discounted to the present using a range of discount rates
from 14.2% to 15.2%. The discount rate ranges were selected based upon a
weighted average cost of capital analysis of PanAmSat. Using the financial
information and forecasts provided by management of PanAmSat, Morgan Stanley
derived an implied per share
 
                                      52
<PAGE>
 
equity value range for PanAmSat ranging from $30.66 to $35.40. Morgan Stanley
also derived an implied per share equity value range for PanAmSat based on
applying certain sensitivities to the projections provided by PanAmSat's
management, which indicated an implied per share equity value ranging from
$24.85 to $28.67.
 
  Morgan Stanley calculated terminal values for Galaxy by applying perpetual
growth rates, valued as of June 30, 1997, in the range of 6.5% to 7.0% to the
unlevered free cash flow in fiscal 2003, representing a range of estimated
long-term cash flow growth rates for Galaxy. The unlevered free cash flow
streams and terminal values for Galaxy were then discounted to the present
using a range of discount rates from 12.7% to 13.7%. The discount rate ranges
were selected based upon a weighted average cost of capital analysis of
Galaxy. Using the financial information and forecasts provided by management
of HCI, Morgan Stanley derived an implied equity value range for Galaxy. This
analysis indicated an implied equity value range for Galaxy for the case where
Galaxy's plan to expand internationally through the launch of certain
satellites (Galaxy XIII-i, Galaxy XIV-i, Galaxy XV-i and Galaxy XVI-i) was
fully implemented, of $3.8 billion to $4.6 billion. Morgan Stanley also
derived an implied equity value range for Galaxy for the case where Galaxy's
international expansion plan was partially implemented, of $3.1 billion to
$3.7 billion. In the case where Galaxy's international expansion plan was not
implemented, the implied equity value of Galaxy ranged from $2.2 billion to
$2.5 billion.
 
  Relative Contribution Analysis. Morgan Stanley analyzed the pro forma
contribution of each of PanAmSat and Galaxy to New PanAmSat. Such analysis
included, among other things, relative contributions of equity value
determined in accordance with the discounted cash flow methodology described
above, sales and EBITDA, tangible invested capital, tangible book value, and
contract revenue backlog. Morgan Stanley observed that, depending on the full,
partial or non-implementation of Galaxy's international expansion plan,
PanAmSat would contribute a range of 42.5% to 56.4% of the discounted cash
flow equity value of New PanAmSat, 41.5% to 55.1% of 1996 to 1998 projected
sales, 40.1% to 55.3% of 1996 to 1998 projected EBITDA, 51.3% of the tangible
invested capital estimated as of June 30, 1997, 43.6% of the tangible book
value estimate as of June 30, 1997 and 46.4% of the contract revenue backlog
as of August 31, 1996.
 
  Pro Forma Analysis. Morgan Stanley analyzed the pro forma impact of the
Reorganization on New PanAmSat. Such analysis was based on cash flow estimates
for the fiscal years 1996 through 2000 based on financial projections prepared
by the respective managements of PanAmSat and Galaxy. Morgan Stanley noted
that PanAmSat's one year forward EBITDA multiple based on financial
projections prepared by management was 10.6x on September 16, 1996. Morgan
Stanley observed that if New PanAmSat traded at between 8.5x to 9.5x pro forma
estimated EBITDA for 1998, then this would result in an estimated per share
equity value in June 1997 for New PanAmSat ranging from $27.96 to $33.37.
Morgan Stanley also analyzed the estimated trading performance of New PanAmSat
based on the combined discounted cash flow values of PanAmSat and Galaxy. This
analysis indicated that the estimated trading value range of New PanAmSat in
June 1997 for the case where Galaxy's international expansion plan was fully
implemented of $34.33 to $42.78 per share. In the case where such expansion
plan was partially implemented, the estimated trading value of New PanAmSat
ranged from $29.61 to $37.18 per share. In the case where Galaxy's
international expansion plan was not implemented at all, the estimated trading
value of New PanAmSat ranged from $23.84 to $29.21 per share.
 
  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. In
arriving at its opinion, Morgan Stanley considered the results of all of its
analyses as a whole and did not attribute any particular weight to any
particular analysis or factor considered by it. Furthermore, selecting any
portions of Morgan Stanley's analyses, without considering all analyses, would
create an incomplete view of the process underlying the Morgan Stanley
Opinion. In addition, Morgan Stanley may have deemed various assumptions more
or less probable than other assumptions, so that the ranges of valuations
resulting for any particular analysis described above should not be taken to
be Morgan Stanley's view of the actual value of PanAmSat, Galaxy or New
PanAmSat.
 
  In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of PanAmSat or HCI. The
analyses performed by Morgan Stanley are not necessarily indicative of actual
values,
 
                                      53
<PAGE>
 
which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as a part of the Morgan Stanley
Opinion and were provided to the PanAmSat Board in connection with the
delivery of the Morgan Stanley Opinion. The analyses do not purport to be
appraisals or to reflect the prices at which PanAmSat, Galaxy or New PanAmSat
might actually be sold. Because such estimates are inherently subject to
uncertainty, none of PanAmSat, HCI or Morgan Stanley nor any other person
assumes responsibility for their accuracy. In addition, as described above,
the Morgan Stanley Opinion, including Morgan Stanley's presentation to the
PanAmSat Board, was one of many factors taken into consideration by the
PanAmSat Board in making its determination to approve the Merger and the
Univisa Contribution. Consequently, the Morgan Stanley analyses described
above should not be viewed as determinative of the opinion of the PanAmSat
Board with respect to the value of PanAmSat, Galaxy or New PanAmSat.
 
  The PanAmSat Board retained Morgan Stanley based upon its experience and
expertise. Morgan Stanley is an internationally recognized investment banking
and advisory firm. Morgan Stanley, as part of its investment banking business,
is continually engaged in the valuation of businesses and securities in
connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for corporate and other
purposes. Morgan Stanley is a full-service securities firm engaged in
securities trading and brokerage activities, as well as providing investment
banking and financial advisory services. In the ordinary course of its trading
and brokerage activities, Morgan Stanley or its affiliates may at any time
hold long or short positions, and may trade or otherwise effect transactions,
for its own account or the accounts of customers, in securities of PanAmSat or
General Motors (including its GMH "targeted" stock). In the past, Morgan
Stanley and its affiliates have provided financial advisory services to
PanAmSat, Televisa and HCI and certain of their affiliates, including acting
as lead underwriter in connection with the IPO in September 1995, acting as
lead underwriter in connection with the public offering of the PAS Preferred
Stock in April 1995 and in connection with financial advice involving the DTH
joint venture in December 1995, and has received fees of approximately $16
million for rendering such services in the past two years to PanAmSat and its
affiliates. In addition, as of the date of the opinion and concurrently with
the negotiation of the Merger, the Univisa Contribution and the Asset
Contribution and at the request of Televisa, certain principal investing funds
affiliated with Morgan Stanley engaged in preliminary discussions with
Televisa concerning the potential acquisition or financing of some or all of
the New PAS Common Stock to be received by S Company.
 
  Pursuant to an engagement letter between PanAmSat and Morgan Stanley,
PanAmSat agreed to pay Morgan Stanley (i) an advisory fee estimated to be
$250,000 in the event the Merger, the Univisa Contribution and the Asset
Contribution are not consummated and, (ii) if the Merger, the Univisa
Contribution and the Asset Contribution are consummated, a transaction fee
equal to approximately $12,000,000. Any advisory fees previously paid will be
credited against the transaction fee. In addition to the foregoing
compensation, PanAmSat agreed to reimburse Morgan Stanley for its expenses,
including reasonable fees and expenses of its counsel, and to indemnify Morgan
Stanley for liabilities and expenses arising out of the engagement and the
transactions in connection therewith, including liabilities under federal
securities laws.
 
ACCOUNTING TREATMENT
 
  The Merger, the Univisa Contribution and the Asset Contribution will be
accounted for under the purchase method of accounting in accordance with
generally accepted accounting principles, with Galaxy as the acquirer of
PanAmSat. Under the purchase method of accounting, the purchase price of
PanAmSat will be allocated to the assets acquired and liabilities assumed
based upon their fair values, with the excess purchase consideration allocated
to goodwill. The results of New PanAmSat's operations will include the results
of operations of PanAmSat and Galaxy commencing at the Effective Time.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of the material U.S. federal income tax
consequences of the Merger to PanAmSat and its stockholders. The summary is
based upon the Internal Revenue Code of 1986, as amended
 
                                      54
<PAGE>
 
and all regulations promulgated thereunder (collectively, the "Code"),
administrative pronouncements, judicial decisions, and subsequent changes to
any of the foregoing which may affect the tax consequences described herein.
This summary does not purport to be a comprehensive description of all of the
tax consequences applicable to a particular taxpayer. In particular, this
summary does not address the tax treatment to holders subject to special tax
rules, such as banks, insurance companies, dealers in securities or
stockholders who acquired PAS Common Stock pursuant to the exercise of
employee stock options or otherwise as compensation. In addition, except as
set forth below, this summary only applies to holders (a) who are U.S.
citizens or residents, U.S. corporations, partnerships or other entities
created or organized under the laws of the United States, or estates or
trusts, the income of which is subject to U.S. federal income taxation
regardless of its source and (b) that hold shares as capital assets.
Stockholders are urged to consult their tax advisors as to the particular U.S.
federal income tax consequences to them of the Merger and as to the foreign,
state, local and other tax consequences thereof.
 
  Chadbourne & Parke LLP has provided an opinion to the effect that, under
current law, the transfer of PAS Ordinary Common Stock or PAS Class A Common
Stock by the stockholders of PanAmSat to New PanAmSat pursuant to the Merger
in exchange for the Merger Consideration (as defined below) will constitute a
transfer described in Section 351 of the Code, and accordingly, that the
Merger will have the tax consequences set forth below. Such opinion is subject
to the conditions, qualifications and assumptions set forth therein and has
been filed as an exhibit to the Registration Statement of which this Proxy
Statement/Prospectus is a part. Opinions of counsel are not binding on the
Internal Revenue Service ("IRS") or the courts, and the parties do not intend
to request a ruling from the IRS with respect to the Merger. Accordingly,
there can be no assurance that the IRS will not challenge such conclusion or
that a court will not sustain such challenge.
 
  Tax Consequences of the Merger to Stockholders. The holders of PAS Ordinary
Common Stock or PAS Class A Common Stock that receive solely New PAS Common
Stock will not recognize gain or loss as a result of the Merger. The holders
of PAS Ordinary Common Stock or PAS Class A Common Stock that receive solely
cash consideration will recognize gain or loss equal to the difference between
the cash consideration and the tax basis of their shares. Such gain, if any,
will be long-term capital gain if such PAS Ordinary Common Stock or PAS Class
A Common Stock was held for more than one year at the time of consummation of
the Merger. Any increase in the cash portion of the Merger Consideration (as
defined below) as a result of the Merger not closing on or before September
20, 1997, will constitute additional cash consideration received in the Merger
rather than interest income.
 
  Subject to the discussion below concerning fractional shares, holders of PAS
Ordinary Common Stock or PAS Class A Common Stock who receive both cash
consideration and New PAS Common Stock will recognize gain measured by the
lesser of (i) the excess, if any, of (x) the sum of the fair market value (at
the Effective Time) of the New PAS Common Stock and cash consideration
received by them over (y) the aggregate tax basis of their shares of PAS
Ordinary Common Stock or PAS Class A Common Stock, and (ii) the cash
consideration received by them (not including any cash received in lieu of
fractional shares as discussed below). Such gain, if any, will be long-term
capital gain if such PAS Ordinary Common Stock or PAS Class A Common Stock was
held for more than one year at the time of consummation of the Merger. A loss
would not be recognized by such holder. A stockholder who holds more than one
block of PAS Ordinary Common Stock or PAS Class A Common Stock (i.e., shares
acquired at different times or prices) will determine the amount of gain
recognized and loss not recognized pursuant to the Merger separately with
respect to each such block of PAS Common Stock. For this purpose, all of the
cash consideration and New PAS Common Stock received by a holder of PAS
Ordinary Common Stock or PAS Class A Common Stock will be allocated
proportionately among the blocks of PAS Ordinary Common Stock or PAS Class A
Common Stock surrendered by such holder.
 
  The aggregate tax basis of the shares of New PAS Common Stock received by
PanAmSat's stockholders, including the fractional shares deemed to be received
(as discussed below), will be the same as the aggregate tax basis of the
shares of PAS Ordinary Common Stock or PAS Class A Common Stock exchanged
therefor (i) increased by the gain recognized (as calculated above) and (ii)
decreased by the cash consideration received (other than cash received in lieu
of fractional shares). The holding period of the shares of New PAS Common
 
                                      55
<PAGE>
 
Stock received in the Merger will include the holding period of the shares of
PAS Ordinary Common Stock or PAS Class A Common Stock surrendered therefor.
 
  PanAmSat stockholders who receive cash in lieu of fractional shares of New
PAS Common Stock will be treated as having received such fractional shares
pursuant to the Merger and then as having sold those fractional shares in the
market for cash. Such stockholders will recognize gain or loss with respect to
such fractional shares in an amount equal to the difference between the tax
basis allocated to such fractional shares (as calculated above), and the cash
received in respect thereof. Any such gain or loss will be capital gain or
loss and will constitute long-term capital gain or loss if the holding period
of the PAS Ordinary Common Stock or PAS Class A Common Stock in exchange for
which such fractional shares are deemed issued (as determined above) exceeds
one year.
 
  Backup Withholding. Certain non-corporate stockholders may be subject to
backup withholding at a rate of 31% on payments of cash consideration and cash
with respect to fractional shares. Backup withholding will not apply, however,
to a stockholder who furnishes a correct taxpayer identification number or
certification of foreign status and makes any other required certification or
who otherwise is exempt from backup withholding. Generally, a stockholder of
PanAmSat will provide such certification on Form W-9 (Request for Taxpayer
Identification Number and Certification) or on Form W-8 (Certificate of
Foreign Status).
 
  Reporting Requirements. Each PanAmSat stockholder (other than stockholders
that receive solely the Standard Cash Consideration (as defined below) for
their shares or who exercise and perfect dissenters' rights as objecting
stockholders, as applicable) will be required to retain records and file with
such holder's U.S. federal income tax return a statement setting forth certain
facts relating to the Merger. It is also expected that such stockholders will
be asked to indicate in the letter of transmittal their tax basis in the
shares of PAS Ordinary Common Stock or PAS Class A Common Stock surrendered by
them pursuant to the Merger.
 
  Tax Consequences to New PanAmSat and PanAmSat. No income, gain or loss will
be recognized by New PanAmSat or PanAmSat pursuant to the Merger. In addition,
no income, gain or loss will be recognized by New PanAmSat as a result of the
Asset Contribution or the Univisa Contribution.
 
  Tax Consequences to Stockholders upon Exercise of Objecting or Dissenting
Stockholders' Rights. A holder of PAS Ordinary Common Stock or PAS Class A
Common Stock who exercises and perfects dissenters' right or rights of
objecting stockholders, as applicable, with respect to all stock owned
actually or constructively, will generally recognize capital gain or loss
equal to the difference between the amount of cash received (other than in
respect of interest awarded by a court) and such stockholder's tax basis in
his or her shares of stock. Such capital gain or loss will be long-term
capital gain or loss if such shares have a holding period exceeding one year
at the time of the consummation of the Merger. Interest, if any, awarded by a
court to an objecting or dissenting stockholder will be includible in such
stockholder's income as ordinary income for U.S. federal income tax purposes.
 
REGULATORY APPROVALS
 
  HSR Act and Antitrust. Under the HSR Act, the Merger may not be consummated
until notifications have been given and certain information has been furnished
("HSR Filings") to the Antitrust Division and the FTC and specified waiting
period requirements have been satisfied. Each of Televisa's ultimate parent
entity, two holders of PAS Class A Common Stock and General Motors have made
HSR Filings. All of such filings were made by November 5, 1996, and the
specified waiting periods under the HSR Act have expired without a Request for
Additional Information by the Antitrust Division or the FTC. Accordingly, no
antitrust approvals are required from the Antitrust Division or the FTC.
 
  State or federal antitrust authorities may still bring legal action under
the antitrust laws. Private parties may also seek to take legal action under
the antitrust laws under certain circumstances.

  FCC Approval Process. Consummation of the Reorganization was subject to the
prior approval of the FCC. On October 8, 1996, the parties filed applications
with the FCC (collectively, the "FCC Applications") requesting: (i) consent to
transfer of control of the FCC licenses, permits and authorizations held by
PanAmSat Licensee Corp. and PanAmSat Carrier Services, Inc. from the voting
trust created by the Voting Trust Agreement (the "Voting Trust") to New
PanAmSat; (ii) consent to a pro forma assignment to New PanAmSat of the FCC
licenses, permits and authorizations held by HCG and HCSS; (iii) consent to a
pro forma transfer of control to New PanAmSat of HCS and HCCS; and (iv)
associated waivers relating to certain pending FCC applications. The FCC
granted these applications on April 4, 1997, and the applicable appeal period
will expire on May 5, 1997.
 
AGREEMENT OF THE CLASS A HOLDERS AND THE CLASS B HOLDER TO VOTE IN FAVOR OF
THE REORGANIZATION
 
  Concurrently with the execution of the Reorganization Agreement, (i) S
Company and the Class B Holder, (ii) the Class A Holders, along with the Class
A Trustee, and (iii) HCI and HCG entered into the Principal Stockholders
Agreement. Pursuant to the Principal Stockholders Agreement, each of the Class
A Holders, the Class A Trustee and the Class B Holder has agreed to vote all
shares of PAS Common Stock, for which such holder has the right to vote, for
approval and adoption of the Reorganization Agreement and the Merger Agreement
and to take any actions required in furtherance thereof. As of the Record
Date, the Class A Holders and the Class B Holder owned (i) 100% of the
outstanding shares of PAS Class A Common Stock, (ii) 100% of the outstanding
shares of PAS Class B Common Stock and (iii) approximately 50.1% of the
outstanding shares of PAS Ordinary Common Stock. In addition, the Principal
Stockholders Agreement restricts the ability of each holder of PAS Class A
Common Stock and PAS Class B Common Stock to sell or transfer any of their
shares, subject to certain exceptions. See "OTHER AGREEMENTS--Principal
Stockholders Agreement."
 
STOCK EXCHANGE LISTINGS
 
  In the Reorganization Agreement, New PanAmSat has agreed to use reasonable
efforts to cause the shares of New PAS Common Stock, which are to be issued
pursuant to the Reorganization, to be listed for trading on either the New
York Stock Exchange (the "NYSE") or the Nasdaq. New PanAmSat has obtained
conditional approval for the listing of New PAS Common Stock on the Nasdaq. It
is presently anticipated that the PAS Ordinary Common Stock, which is
currently listed on the Nasdaq under the symbol "SPOT," will be replaced by
the listing of New PAS Common Stock and trade under the same symbol.
 
FEDERAL SECURITIES LAWS CONSEQUENCES
 
  All shares of New PAS Common Stock received by holders of PAS Ordinary
Common Stock and PAS Class A Common Stock in the Merger will be freely
transferable, except that (i) shares of New PanAmSat received by persons who
are deemed "affiliates" (as such term is defined under the Securities Act) of
PanAmSat prior to the Merger may be resold by them only in transactions
permitted by the resale provisions of Rule 145 promulgated under the
Securities Act (or Rule 144 in the case of such persons who become affiliates
of New PanAmSat) or as otherwise permitted under the Securities Act and (ii)
shares of New PAS Common Stock issued to the Class A Holders and S Company
will be subject to restrictions under the Stockholder Agreement. Persons who
may be deemed to be affiliates of PanAmSat or New PanAmSat generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include certain officers and directors of
such party as well as principal stockholders of such party. The Reorganization
Agreement requires PanAmSat to use reasonable best efforts to deliver or cause
to be delivered to New PanAmSat, prior to the Closing Date, from each
affiliate of PanAmSat, a letter agreement to the effect that such person will
not offer or sell or otherwise dispose of any of the shares of New PAS Common
Stock issued to such persons in or pursuant to the Merger in violation of the
Securities Act or the rules and regulations promulgated by the Commission
thereunder.

APPRAISAL RIGHTS
 
  Holders of shares of PAS Common Stock will be entitled to appraisal rights
under Section 262 of the DGCL as to shares owned by them. Section 262 is
reprinted in its entirety as Appendix I to this Proxy Statement/Prospectus.
The Class A Holders and the Class B Holder, however, will vote their shares in
favor of the Merger and therefore will not be entitled to appraisal rights.
 
  The following discussion is not a complete statement of the law relating to
appraisal rights and is qualified by reference to Appendix I. THIS DISCUSSION
AND APPENDIX I SHOULD BE REVIEWED CAREFULLY BY ANY HOLDER OF PANAMSAT COMMON
STOCK WHO WISHES TO EXERCISE STATUTORY APPRAISAL RIGHTS OR WHO WISHES TO
PRESERVE THE RIGHT TO DO SO BECAUSE FAILURE TO STRICTLY COMPLY WITH THE
PROCEDURES SET FORTH HEREIN AND THEREIN WILL RESULT IN THE LOSS OF APPRAISAL
RIGHTS.
 
  A record holder of shares of PAS Common Stock who makes the demand described
herein with respect to such shares, who continuously is the record holder of
such shares through the Effective Time, and who neither votes in favor of the
Merger nor consents thereto in writing, will be entitled to seek an appraisal
by the Delaware Court of Chancery of the fair value of his or her shares of
Common Stock. All references in this summary to a "stockholder" are to the
record holder of the shares of PAS Common Stock as to which appraisal rights
are asserted. A person having a beneficial interest in shares of PAS Common
Stock that are held of record in the name of another person, such as a broker
or nominee, must act promptly to cause the record holder to properly follow
the steps summarized below and in a timely manner to perfect whatever
appraisal rights the record holder may have.
 
  Under Section 262, where a merger is to be submitted for adoption at a
meeting of stockholders, a constituent corporation must notify each of the
record holders of its stock who were such as of the record date and for whom
appraisal rights are available, not less than 20 days prior to such meeting,
of the availability of such appraisal rights and include in each such notice a
copy of Section 262. This Proxy Statement/Prospectus shall constitute such
notice to the record holders of PAS Common Stock.
 
  HOLDERS OF PAS COMMON STOCK WHO DESIRE TO EXERCISE THEIR APPRAISAL RIGHTS
MUST NOT VOTE IN FAVOR OF THE MERGER. EACH STOCKHOLDER ELECTING TO DEMAND THE
APPRAISAL OF HIS OR HER SHARES OF PAS COMMON STOCK ("DISSENTING SHARES") MUST
DELIVER TO PANAMSAT, BEFORE THE TAKING OF THE VOTE ON THE MERGER AT THE
SPECIAL MEETING, A WRITTEN DEMAND FOR APPRAISAL OF HIS OR HER SHARES OF PAS
COMMON STOCK. ANY SUCH STOCKHOLDER MUST MAIL OR DELIVER HIS OR HER WRITTEN
DEMAND TO THE SECRETARY OF PANAMSAT AT ONE PICKWICK PLAZA, GREENWICH,
CONNECTICUT 06830. Such demand for appraisal will be sufficient if it
reasonably informs PanAmSat of the stockholder's identity and that the
stockholder intends to thereby demand appraisal of his or her shares of PAS
Common Stock. Appraisal rights will not be available under Section 262 if the
stockholder does not continuously hold through the Effective Time the shares
of PAS Common Stock with respect to which appraisal is being demanded. Within
ten days after the Effective Time, PanAmSat must provide notice of the
Effective Time to all stockholders who have therefore complied with Section
262.
 
  A demand for appraisal must be executed by, or by another as agent for, the
stockholder of record, fully and correctly, as such stockholder's name appears
on PanAmSat's list of stockholders. Beneficial owners who are not record
owners and who desire their corresponding record holder to exercise appraisal
rights should instruct the record holder to comply strictly with the statutory
requirements with respect to the exercise of appraisal rights BEFORE the
taking of the vote on the Merger at the Special Meeting. If the shares of PAS
Common Stock are held of record in a fiduciary capacity, such as by a trustee,
guardian or custodian, such demand must be executed by the fiduciary or by an
agent on his behalf. If the shares of PAS Common Stock are held of record by
more than one person, as in a joint tenancy or tenancy in common, such demand
must be executed by all joint owners. An authorized agent, including an agent
for two or more joint owners, may execute the demand for appraisal for a
stockholder of record; however, the agent must identify the record owner and
expressly disclose the fact that, in exercising the demand, such person is
acting as agent for the record holder. If a stockholder
 
                                      58
<PAGE>
 
holds shares of PAS Common Stock through a broker who in turns holds the
shares through a central securities depository nominee, a demand for appraisal
of such shares must be made by or on behalf of the depository nominee and must
identify the depository nominee as the record holder.
 
  A record holder, such as a broker, who holds shares of PAS Common Stock as
nominee for others, may exercise appraisal rights with respect to the shares
of PAS Common Stock held for all or less than all beneficial owners of shares
of PAS Common Stock as to which such person is the record holder. In such case
the written demand must set forth the number of shares of PAS Common Stock
covered by such demand. Where the number of shares of PAS Common Stock is not
expressly stated, the demand will be presumed to cover all shares of PAS
Common Stock outstanding in the name of such record holder.
 
  Within 120 days after the Effective Time, either PanAmSat, as the surviving
corporation in the Merger, or any stockholder who previously has complied with
the required conditions of Section 262 and who is otherwise entitled to
appraisal rights may file a petition in the Delaware Court of Chancery
demanding a determination of the fair value of the shares of PAS Common Stock.
If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Court of Chancery will determine which stockholders are
entitled to appraisal rights and will appraise the shares of PAS Common Stock
owned by such stockholders, determining the fair value of such shares of PAS
Common Stock exclusive of any element of value arising from the accomplishment
or expectation of the Merger, together with a fair rate of interest, if any,
to be paid upon the amount determined to be the fair value. In determining
such fair value, the Delaware Court of Chancery is to take into account all
relevant factors. In Weinberger v. UOP Inc., decided February 1, 1983, the
Delaware Supreme Court discussed the factors that could be considered in
determining fair value in an appraisal proceeding, stating that "proof of
value by any techniques or methods which are generally considered acceptable
in the financial community and otherwise admissible in court" should be
considered and that "[f]air price obviously requires consideration of all
relevant factors involving the value of a company." The Delaware Supreme Court
has stated that in making this determination of fair value the court must
consider market value, asset value, dividends, earnings prospects, the nature
of the enterprise and any other facts which could be ascertained as of the
date of the merger which throw any light on future prospects of the merged
corporation. Section 262 provides that fair value is to be "exclusive of any
element of value arising from the accomplishment or expectation of the
merger." In Cede & Co. v. Technicolor, Inc., decided October 21, 1996, the
Delaware Supreme Court stated that such exclusion is a "narrow exclusion
[that] does not encompass known elements of value," but which rather applies
only to the speculative elements of value arising from such accomplishment or
expectation. In Weinberger, the Delaware Supreme Court construed Section 262
to mean that "elements of future value, including the nature of the
enterprise, which are known or susceptible of proof as of the date of the
merger and not the product of speculation, may be considered." In addition,
Delaware courts have decided that the statutory appraisal remedy, depending on
the factual circumstances, may or may not be a stockholder's exclusive remedy
in connection with transactions such as the Merger.
 
  Stockholders considering seeking appraisal should have in mind that the
"fair value" of their shares of PAS Common Stock determined under Section 262
could be more than, the same as or less than the market value of such
securities or the Merger Consideration. The cost of the appraisal proceeding
may be determined by the Delaware Court of Chancery and taxed against the
parties as the Delaware Court of Chancery deems equitable in the
circumstances. Upon application of a dissenting stockholder, the Delaware
Court of Chancery may order that all or a portion of the expenses incurred by
any dissenting stockholder in connection with the appraisal proceeding,
including without limitation, reasonable attorneys' fees and the fees and
expenses of experts, be charged pro rata against the value of all shares of
PAS Common Stock entitled to appraisal.
 
  Within 120 days after the Effective Time, any stockholder who has previously
complied with the requirements for exercise of appraisal rights as discussed
above is entitled, upon written request, to receive from the surviving
corporation in the Merger a statement setting forth the aggregate number of
shares of PAS Common Stock not voted in favor of the Merger and with respect
to which demands for appraisal have been made and the aggregate number of
holders of such shares. Such statement must be mailed to the stockholders
within 10 days after the written request therefor has been received by the
Surviving Corporation.
 
                                      59
<PAGE>
 
  Any stockholder who has duly demanded appraisal in compliance with Section
262 will not, from and after the Effective Time, be entitled to vote for any
purpose the shares of PAS Common Stock subject to such demand or to receive
payment of dividends or other distribution on such shares of PAS Common Stock,
except for dividends or distributions payable to stockholders of record at a
date prior to the Effective Time.
 
  At any time within 60 days after the Effective Time, any stockholder shall
have the right to withdraw his or her demand for appraisal and to accept the
terms offered in the Merger whereby such holder will be deemed to have made a
Standard Election (as hereafter defined); after this period, the stockholder
may withdraw his or her demand for appraisal only with the consent of New
PanAmSat. If no petition for appraisal is filed with the Delaware Court of
Chancery within 120 days after the Effective Time, stockholders' rights to
appraisal shall cease. Inasmuch as PanAmSat will have no obligation to file
such a petition, and has no present intention to do so, any stockholder who
desires such a petition to be filed is advised to file it on a timely basis.
However, no petition timely filed in the Delaware Court of Chancery demanding
appraisal shall be dismissed as to any stockholder without the approval of the
Delaware Court of Chancery, and such approval may be conditioned upon such
terms as the Delaware Court of Chancery deems just. Any holder of PAS Common
Stock who effectively withdraws his or her demand for appraisal, or whose
right to an appraisal shall cease, shall be deemed to have lost such holder's
appraisal rights.
 
INTERESTS OF CERTAIN PERSONS IN THE REORGANIZATION
 
  In considering the Reorganization Agreement, the Merger Agreement and the
transactions contemplated thereby, PanAmSat's stockholders should be aware
that certain members of PanAmSat's management and the PanAmSat Board and the
Principal Stockholders have certain interests in the Reorganization that are
different from and in addition to the interests of stockholders of PanAmSat
generally:
 
  Televisa. Televisa, through its subsidiary Univisa, indirectly owns all of
the shares of PAS Class B Common Stock. The primary purpose of the Univisa
Contribution is to facilitate the consummation of the Merger and the sale of
the DTH Options and to provide a tax efficient structure for Televisa to
participate indirectly in the Reorganization. See "THE REORGANIZATION--
Background of the Reorganization." As a result of the structure of the Univisa
Contribution, S Company will be offered consideration equal in amount and form
(subject to proration, as applicable) to that offered to the holders of the
PAS Ordinary Common Stock and the PAS Class A Common Stock. See "--Background
of the Reorganization" and "THE UNIVISA CONTRIBUTION AGREEMENT."
 
  In addition, concurrently with the Merger and immediately following the
Univisa Contribution, New PanAmSat will repurchase for $225 million 7.5
million shares of New PAS Common Stock received by S Company in connection
with the Univisa Contribution. Following such Share Repurchase, either
Televisa, S Company and/or their designees will purchase for $225 million all
of PanAmSat's interest in the DTH Options, pursuant to the DTH Option Purchase
Agreement. It is a condition to the Merger, the Univisa Contribution and the
Asset Contribution that the DTH Sale shall have occurred. See "THE
REORGANIZATION AGREEMENT--Conditions to the Reorganization" and "THE DTH
SALE."
 
  General Severance Policy. On April 22, 1996, the PanAmSat Board adopted a
general severance policy for all employees providing for payments upon
termination without cause equal to: (i) one week of salary for every year of
service up to five years, (ii) two weeks of salary for every year of service
over five years and (iii) minimum and maximum severance levels depending upon
the nature of such employee's position at PanAmSat. Under the policy, the
Named Executive Officers are eligible to receive a minimum of four weeks'
salary and a maximum of 52 weeks' salary as severance. Other employees of
PanAmSat are eligible to receive a minimum of two weeks' salary and a maximum
of 29 weeks' salary, depending on their classification, as severance.
 
  Employee Separation Plan. On April 22, 1996, the PanAmSat Board also adopted
an Employee Separation Plan providing that for a one-year period following a
"change of control" any employee who is terminated
 
                                      60
<PAGE>
 
without cause is eligible to receive, in addition to the benefits covered by
PanAmSat's general severance policy, six months' continuation of such
employee's: (i) base salary and annual cash bonus (which shall be prorated for
such period), (ii) medical and dental insurance benefits, (iii) long-term
disability insurance benefits and (iv) life and accidental death and
dismemberment insurance benefits ("Welfare Benefits"). The Employee Separation
Plan applies to all employees of PanAmSat, other than any employee who is
otherwise covered by a Severance Agreement (as defined below). The Employee
Separation Plan shall be effective for one year and is renewable at PanAmSat's
option. PanAmSat has extended the Employee Separation Plan until the first
anniversary following the Closing Date.
 
  Generally, a "change in control" will be deemed to have occurred under the
Employee Separation Plan or the Severance Agreements referred to below upon:
(a) the sale of all or substantially all of the assets of PanAmSat; (b) the
loss by the holders of the PAS Class A Common Stock of the power to elect a
majority of the PanAmSat Board; (c) a majority of the PanAmSat Board ceasing
to consist of nominees of the holders of the PAS Class A Common Stock; or (d)
a complete liquidation or dissolution of PanAmSat. For purposes of the
Employee Separation Plan and the Severance Agreements, the Merger will
constitute a "change in control."
 
  Executive Severance Pay Program. On April 22, 1996, the PanAmSat Board
adopted an executive severance pay program that would be triggered by a change
in control. The program covers the Named Executive Officers and approximately
55 key employees. The program consists of individual change in control
agreements ("Severance Agreements") for all covered officers and key
employees.
 
  The principal purposes of the Employee Separation Plan and the executive
severance pay program are (a) to help assure that executives give impartial
consideration to evaluating and negotiating a potential business combination
which is in the best interest of PanAmSat's stockholders, but which may result
in the loss of, or reduction in, the executive's job; (b) to make PanAmSat's
plans more competitive with severance plans of other comparable companies and
to facilitate PanAmSat's ability to attract, retain and motivate talented
employees in an uncertain, rapidly consolidating communications industry
environment; (c) to provide security and ensure that key executives are
retained during critical negotiations prior to and through any change in
control; and (d) to avoid the legal expense and reduce the management time
associated with contested terminations, to allow for better forecasts of
amounts due to employees terminated after a change in control and to provide
for a general release of legal claims associated with such terminations.
 
  The benefits under the Severance Agreements covering Frederick A. Landman
and Lourdes Saralegui would be triggered if, within two years following a
change in control, (i) the covered officer's employment is terminated with or
without cause by PanAmSat or (ii) the covered officer voluntarily terminates
his or her employment.
 
  The benefits under the Severance Agreements covering Patrick J. Costello,
James W. Cuminale and Robert A. Bednarek would be triggered if, (x) within two
years following a change in control, (i) the covered officer's employment is
terminated without cause, (ii) the covered officer's responsibilities and/or
duties are materially reduced or changed such that they are inconsistent with
such officer's former responsibilities or duties, including a change in
location of employment of more than 35 miles from the officer's current
location of employment (unless the move is to New York City from PanAmSat's
Greenwich offices), or (iii) PanAmSat reduces or fails to pay or award to the
covered officer when due any salary, bonus or benefits or (y) the covered
officer voluntarily terminates employment at any time during the 30 days
following the one year anniversary of the change in control.
 
  The benefits under the Severance Agreements covering all other key employees
would be triggered if, within two years following a change in control, (i) the
covered officer's employment is terminated without cause, (ii) the covered
officer's responsibilities and/or duties are materially reduced or the covered
officer's responsibilities are changed such that they are inconsistent with
such officer's former responsibilities, including relocation of employment of
more than 35 miles from the officer's current location of employment (unless
the covered officer is moved to New York City from PanAmSat's Greenwich
offices), or (iii) PanAmSat reduces or fails to pay or award to the covered
officer when due any salary, bonus, or benefits.
 
                                      61
<PAGE>
 
  Each Severance Agreement is effective for three years from May 1, 1996 and
will automatically be extended for additional one-year periods unless PanAmSat
gives a termination notice prior to the second anniversary or any subsequent
anniversary of the Severance Agreement.
 
  Severance benefits payable to officers covered by Severance Agreements are
determined by multiplying base salary and a cash bonus component by 3 in the
case of the Named Executive Officers and by 1.5 in the case of remaining key
employees. Covered officers are entitled to Welfare Benefits until the earlier
of (i) 36 months in the case of Frederick A. Landman and Lourdes Saralegui,
(ii) 24 months in the case of the remaining three Named Executive Officers and
(iii) 18 months in the case of the remaining key employees, or the obtaining
of similar benefits on reemployment. The Severance Agreements restrict the
ability of (x) the Named Executive Officers and (y) the remaining key
employees to compete with PanAmSat for 18 and 12 month periods, respectively,
following termination from PanAmSat.
 
  PanAmSat has reserved the right to grant additional severance benefits to
certain recently hired key employees. In PanAmSat's discretion, such severance
benefits may be greater than 1.5 but may not exceed 3 times base salary and a
bonus component.
 
  In addition, the Named Executive Officers would be entitled to reimbursement
of any legal fees incurred in connection with the enforcement or defense of
their Severance Agreements. If a Named Executive Officer becomes subject to
the 20% excise tax on excess parachute payments under Section 4999 of the
Code, including, without limitation, as a result of any payments made under
the Stock Plan (as defined below), PanAmSat would be required to make an
additional payment in an amount such that the officer will be in the same
after-tax position as though the 20% excise tax had not been imposed. Under
the executive severance pay program, "bonus" shall generally mean an annual
cash amount that is not less than the greater of the annual cash bonus awarded
to an employee by PanAmSat for the fiscal year preceding the fiscal year in
which a change in control occurs and the bonus set for the fiscal year in
which termination occurs, in any case prorated for a partial year.
 
  Mr. Costello, who will no longer serve as Chief Financial Officer of
PanAmSat after the Closing Date, will be entitled to receive a severance
payment of $975,000 as a result of the Reorganization. See "MANAGEMENT OF NEW
PANAMSAT--Board of Directors" for a description of Mr. Costello's anticipated
role at New PanAmSat.
 
  Stock Incentive Plan. Effective March 2, 1995, PanAmSat adopted the PanAmSat
Corporation Long-Term Stock Investment Plan (the "1995 Stock Plan"), which
provides for the granting of nonqualified stock options ("NQSOs"), incentive
stock options ("ISOs" and, collectively with NQSOs, the "Options"), alternate
appreciation rights ("AARs"), restricted stock, performance units and
performance shares to executive officers and other key employees of PanAmSat,
and to other service providers, including independent contractors of PanAmSat.
PanAmSat has granted to certain of its employees Options under the 1995 Stock
Plan to purchase an aggregate of 1,250,000 shares of Common Stock, including
grants to Frederick A. Landman, Lourdes Saralegui, Patrick J. Costello, James
W. Cuminale and Robert A. Bednarek for 200,000 shares, 150,000 shares, 75,000
shares, 75,000 shares and 75,000 shares, respectively. At the Effective Time,
each of the foregoing holders will receive for each share of PAS Ordinary
Common Stock subject to such Options an amount (subject to applicable
withholding tax) in cash equal to the difference between (i) the Standard Cash
Consideration, and (ii) the per share PAS Ordinary Common Stock exercise price
of such Option, to the extent such difference is a positive number (the
"Option Consideration"), provided that with respect to any person subject to
Section 16(b) of the Exchange Act, any such amount shall be paid as soon as
practicable after the first date payment can be made without liability to such
person under Section 16(b) of the Exchange Act. All but 57,500 of such Options
are exercisable at the price of $17 per share and each will become fully
vested upon consummation of the Merger. See "--THE REORGANIZATION AGREEMENT--
Terms of the Reorganization" and "--Certain Benefits Matters."
 
  After discussions with HCI, PanAmSat did not grant any new options to its
employees in September 1996, the first anniversary of its IPO, as previously
anticipated. Instead, in consultation with HE, PanAmSat engaged
 
                                      62

Mercer to advise as to what companies comparable to PanAmSat would award on an
annual basis in the form of stock options and to assist PanAmSat in
determining the cash value of such stock options. After consulting with
Mercer, PanAmSat set the amount of the cash awards that would be paid in lieu
of stock options. Accordingly, in September 1996 PanAmSat paid cash awards in
the aggregate amount of $4.8 million to 195 employees, including $950,000 to
Mr. Landman, $500,000 to Ms. Saralegui, $300,000 to Mr. Costello, $225,000 to
Mr. Cuminale and $225,000 to Mr. Bednarek.
 
  Registration Rights. Pursuant to the Registration Rights Agreement, the
Registration Rights Holders will have the right, under certain circumstances
and subject to certain conditions, to require New PanAmSat to register under
the Securities Act all or any portion of the shares of New PAS Common Stock
which they hold unless (i) the shares have been effectively registered under
Section 5 of the Securities Act and disposed of pursuant to an effective
Registration Statement, or (ii) all of a holder's shares of New PAS Common
Stock may be freely sold and transferred without restriction under Rule 144 or
Rule 145 under the Securities Act or any successor rule such that, after any
such transfer referred to in this clause (ii), such securities may be freely
transferred without restriction under the Securities Act. Under the
Registration Rights Agreement, the Class A Holders as a group and the Class B
Holder each will be able to demand on three occasions, under certain
circumstances and subject to certain limitations, that New PanAmSat register
their shares under the Securities Act. See "OTHER AGREEMENTS--Registration
Rights Agreement."
 
  Indemnification. The Reorganization Agreement provides that all rights to
indemnification existing on the date of the Reorganization Agreement in favor
of the present or former directors or officers of any of the Contributed
Entities, New PanAmSat or PanAmSat or their respective subsidiaries, will
continue to be in full force and effect for five years after the Closing Date
with respect to matters existing or occurring at or prior to the Closing Date.
New PanAmSat will, to the fullest extent permitted by law, indemnify and hold
harmless such current and former directors from and after the Closing Date
against all losses, claims, damages, costs, expenses, liabilities or judgments
or amounts paid in settlement with the approval of the indemnifying party
(which approval shall not be unreasonably withheld) in connection with any
proceeding based on or arising out of any matter occurring at or prior to the
Closing Date. HCI and PanAmSat, prior to the Closing Date and New PanAmSat,
from and after the Closing Date, will pay the attorneys' fees of any
indemnified person and assist in the vigorous defense of any such matter. The
Reorganization Agreement provides that, with respect to matters arising before
the Closing Date, New PanAmSat will maintain directors' and officers'
liability insurance policies as currently maintained by HCI, the Contributed
Entities, New PanAmSat or PanAmSat, as the case may be, and their respective
subsidiaries, for a period of five years after the Closing Date to the extent
that such policies are obtainable at an annual cost of not greater than 175%
of the last annual premium paid prior to the date of the Reorganization
Agreement. See "THE REORGANIZATION AGREEMENT--Indemnification."
 
 Employment Agreements.
 
  It is anticipated that Frederick A. Landman and Lourdes Saralegui will enter
into employment agreements with New PanAmSat. See "MANAGEMENT OF NEW
PANAMSAT--Executive Officers."
 
MANAGEMENT AND OPERATIONS OF NEW PANAMSAT AND PANAMSAT AFTER THE MERGER
 
  After the Merger, PanAmSat will be a wholly owned subsidiary of New
PanAmSat. PanAmSat will operate as one of New PanAmSat's business units, and
the corporate headquarters of New PanAmSat will be in Greenwich, Connecticut.
 
  Frederick A. Landman, the current president and Chief Executive Officer of
PanAmSat, will be President and Chief Executive Officer and a Director of New
PanAmSat. Other members of the executive management team will include: Lourdes
Saralegui, current Executive Vice President of PanAmSat, who will be Executive
Vice President of New PanAmSat; Carl A. Brown, current Senior Vice President,
Galaxy Satellite Services of HCI, who will be Executive Vice President of New
PanAmSat; Kenneth N. Heintz, current Vice President of Corporate Development
of HE, who will be Executive Vice President and Chief Financial Officer of New
 
                                      63
<PAGE>
 
PanAmSat; James W. Cuminale, current Senior Vice President and General Counsel
of PanAmSat, who will be Senior Vice President, General Counsel and Secretary
of New PanAmSat, and Robert A. Bednarek, current Senior Vice President,
Engineering and Operations of PanAmSat, who will be Senior Vice President and
Chief Technology Officer of New PanAmSat. See "MANAGEMENT OF NEW PANAMSAT."
 
FINANCING IN CONNECTION WITH THE REORGANIZATION
 
  The total amount of funds required to be paid by New PanAmSat as
consideration in the Reorganization is expected to be approximately $1.725
billion, including (i) approximately $1.5 billion to be paid to holders of PAS
Class A Common Stock and PAS Ordinary Common Stock, holders of options to
acquire PAS Ordinary Common Stock and S Company in consideration in the Merger
and the Univisa Contribution and (ii) $225 million to fund the Share
Repurchase. Pursuant to the Assurance Agreement, HE has agreed to lend up to
$1.725 billion to New PanAmSat on the Closing Date. The terms of such New
Financing will be no less favorable than the terms that New PanAmSat would
obtain from a third-party commercial lender. HE intends to borrow from General
Motors the funds necessary to provide the New Financing. Any additional funds
needed by New PanAmSat on the Closing Date will be funded from cash on hand.
The precise terms of the New Financing have not been finalized, but will be
fully negotiated prior to the Closing Date. Generally, HE's provision of the
New Financing will be in the form of a three year term loan bearing interest
at a rate of 2% above the London Inter-Bank Offering Rate (which interest rate
is subject to renegotiation if New PanAmSat attains an investment grade credit
rating or PanAmSat ceases to be subject to the restricted payments and
restrictions on pledging its assets contained in the indentures governing
PanAmSat's existing indebtedness and the certificate of designation for the
PAS Preferred Stock). Under the New Financing, New PanAmSat will be required
to pay seven quarterly installments of $50 million each commencing 15 months
after the Closing Date, with the balance of the loans payable on the maturity
date of the New Financing. In addition, New PanAmSat will be required to make
certain prepayments of principal upon the occurrence of certain events,
including the issuance of equity, the issuance of certain debt, the sale of
material assets of New PanAmSat and the receipt of insurance proceeds. The New
Financing will include covenants that prohibit or limit, among other things,
transactions with affiliates and pledges of New PanAmSat's assets and will
require that New PanAmSat and its subsidiaries maintain a certain consolidated
net worth.
 
  Because the indentures governing PanAmSat's existing debt and the
certificate of designation for the PAS Preferred Stock restrict the use of
PanAmSat's assets as collateral for any new borrowing or its ability to
guarantee indebtedness of others, the terms of the New Financing are less
favorable to New PanAmSat than if New PanAmSat were able to borrow against the
consolidated credit of PanAmSat and Galaxy. See "RISK FACTORS--Substantial
Leverage and Additional Capital Requirements."

                         THE REORGANIZATION AGREEMENT
 
TERMS OF THE REORGANIZATION
 
  The following is a summary of certain provisions of the Reorganization
Agreement, a copy of which is attached hereto as Appendix A, and the Amendment
to the Reorganization Agreement, a copy of which is attached hereto as
Appendix AA, both of which are incorporated herein by reference. The following
summary is qualified by reference to the complete text of the Reorganization
Agreement.
 
  The Merger. Pursuant to the Reorganization Agreement and the Merger
Agreement, at the Effective Time, PAS Merger Corp. will be merged with and
into PanAmSat and all of the outstanding shares of the PAS Class A Common
Stock and the PAS Ordinary Common Stock will be exchanged for the Merger
Consideration (as defined below). At the Effective Time, the separate
corporate existence of PAS Merger Corp. will cease and the internal corporate
affairs of PanAmSat (the "Surviving Corporation") will continue to be governed
by the laws of the State of Delaware. The Merger will be consummated promptly
following receipt of all required governmental approvals and satisfaction or
waiver (where permissible) of the other conditions to the Merger. The Merger
will become effective at the time at which the certificate of merger to be
filed pursuant to the DGCL is accepted for filing by the Secretary of State of
the State of Delaware or such later date and time as may be specified in such
certificate of merger.
 
  The Univisa Contribution. Immediately prior to the Merger, in a separate but
related transaction pursuant to the Univisa Contribution Agreement, New
PanAmSat will acquire from S Company all of the capital stock of Univisa,
which indirectly owns all of the shares of PAS Class B Common Stock. In
connection with the Univisa Contribution, S Company will receive for each
share of PAS Class B Common Stock indirectly owned by Univisa, at S Company's
election, consideration equal in amount and form (subject to proration, as
applicable), to the consideration payable on account of each share of PAS
Class A Common Stock and PAS Ordinary Common Stock in the Merger. See "THE
UNIVISA CONTRIBUTION AGREEMENT" and "THE REORGANIZATION--Background of the
Reorganization" for a description of the reason that the PAS Class B Common
Stock has been treated in the manner set forth above.
 
  The Asset Contribution. Pursuant to the Reorganization Agreement, on the
Closing Date, HCI will cause the Galaxy Assets (as defined below) and the
Galaxy Liabilities (as defined below) to be conveyed to or assumed by New
PanAmSat. In order to effect the foregoing transfer, (x) HCG and HCSS shall
convey to New PanAmSat all right, title and interest in and to the Galaxy
Assets owned by them, and (y) HCI shall convey, transfer, assign and deliver
to New PanAmSat all of HCI's right, title and interest in and to all of the
issued and outstanding shares of common stock of HCS, HCCS and HCJ. For
purposes of the Reorganization Agreement, "Galaxy Assets" include any and all
of the assets, properties, interests and rights owned by or used in the Galaxy
Business (as defined below) of every kind and description, whether located in
HCG, HCSS, HCS, HCCS or HCJ, but excluding certain assets, including all
assets of HCI or its subsidiaries related to HCI's SPACEWAY business, its
mobile telecommunications business, American Mobile Satellite Corporation and
ICO Global Communications. For purposes of the Reorganization Agreement,
"Galaxy Liabilities" include, with certain exceptions, all direct and indirect
liabilities of any type arising out of or relating to the Galaxy Business. For
purposes of the Reorganization Agreement, the "Galaxy Business" means the
business of HE or any of HE's affiliates existing on the Closing Date relating
to (i) the sale or lease of, or the provision of satellite services via,
transponder capacity on satellites operating in geostationary earth orbit in
the C-band, Ka-band and Ku-band frequencies for the transmission of video,
audio and data signals; and (ii) the provision of TT&C services for such
satellites and for other satellites operating in geostationary earth orbit in
the C-band, Ka-band, Ku-band, L-band and UHF-band frequencies or other
frequency bands that may be utilized in the future; but in each case,
excluding the sale or lease of transponder capacity and TT&C services provided
on or for any satellite that has both (x) multiple (six or more) receive and
transmit beams and (y) an on-board satellite payload processor which can
switch uplink signals in one beam to a downlink signal in one of multiple
beams. As consideration for the Asset Contribution, on the Closing Date New
PanAmSat will issue to HCI, HCG and HCSS, in such proportions as HCI shall
determine, an aggregate of 106,622,807 shares of New PAS Common Stock.
 
                                      65
<PAGE>
 
  Corporate Structure Following Reorganization. As a result of the Merger and
the Univisa Contribution, New PanAmSat will own, directly and indirectly, all
of the shares of PAS Common Stock (but not the PAS Preferred Stock, which will
remain outstanding) and PanAmSat will become a wholly owned subsidiary of New
PanAmSat. As a result of the Asset Contribution, New PanAmSat will become the
owner and operator of the Galaxy Business. At the Effective Time, New PanAmSat
will change its corporate name to "PanAmSat Corporation" and PanAmSat will
change its name to "PanAmSat International Systems, Inc."
 
  Certificate of Incorporation and Bylaws. The Reorganization Agreement
provides that the certificate of incorporation of New PanAmSat (the "New
PanAmSat Certificate of Incorporation") and the bylaws of New PanAmSat (the
"New PanAmSat Bylaws") will be in the form attached as Appendices F and G
hereto, respectively. The Reorganization Agreement provides that the PanAmSat
Certificate of Incorporation as in effect at the Effective Time will become
the certificate of incorporation of the Surviving Corporation until duly
amended in accordance with the terms thereof and the DGCL; provided that the
PanAmSat Certificate of Incorporation will be amended prior to the
Reorganization pursuant to the Charter Amendment. See "THE SPECIAL MEETING"
and "PROPOSAL TO APPROVE AND ADOPT THE CHARTER AMENDMENT." The Bylaws of
PanAmSat in effect at the Effective Time will become the Bylaws of the
Surviving Corporation.
 
  Directors and Officers. The directors of PAS Merger Corp. at the Effective
Time will become the directors of the Surviving Corporation until their
successors have been duly elected or appointed in accordance with applicable
law. The officers of PanAmSat at the Effective Time will become the officers
of the Surviving Corporation until their successors have been duly elected or
appointed in accordance with applicable law. See "THE REORGANIZATION--
Management and Operations of New PanAmSat and PanAmSat after the Merger."
 
  Effect of the Merger on the Securities of PanAmSat and PAS Merger Corp. In
addition, at the Effective Time, the shares of the common stock of PAS Merger
Corp. outstanding immediately prior to the Effective Time shall be converted
into and become (a) the number of shares of Class A Common Stock of the
Surviving Corporation that is equal to the number of shares of, and having
terms identical in all respects to, the PAS Class A Common Stock outstanding
immediately prior to the Merger and (b) the number of shares of Common Stock
of the Surviving Corporation that is equal to the number of shares of, and
having terms identical in all respects to, the PAS Ordinary Common Stock
outstanding immediately prior to the Merger. At the Effective Time, (i) all
shares of PAS Class A Common Stock and PAS Ordinary Common Stock held by any
person other than New PanAmSat or any of its subsidiaries shall cease to be
outstanding and shall be canceled and retired, and the holder thereof shall
have no rights except the right to receive, without interest, the Merger
Consideration and cash in lieu of fractional shares as described below, and
(ii) each share of PAS Common Stock held in treasury ("PAS Treasury Stock")
will be canceled and retired without payment of any consideration therefor.
All outstanding shares of PAS Class B Common Stock will remain outstanding and
continue to be held indirectly by Univisa, which will become a subsidiary of
New PanAmSat, as a result of the Univisa Contribution. The PAS Preferred Stock
shall remain outstanding.
 
  Merger Consideration. Pursuant to the Reorganization Agreement, at the
Effective Time each issued and outstanding share of PAS Class A Common Stock
and PAS Ordinary Common Stock other than Dissenting Shares and PAS Treasury
Stock (collectively, the "PAS Shares") will be converted, at the election of
the holder thereof, into one of the following (collectively, the "Merger
Consideration"):
 
    (a) the right to receive (x) an amount in cash equal to one half ( 1/2)
  of the Standard Cash Consideration (as defined below) plus (y) one half (
  1/2) share of New PAS Common Stock (collectively, the "Standard
  Consideration"). The "Standard Cash Consideration" means an amount in cash
  equal to $30, provided that if the Closing has not occurred on or prior to
  September 20, 1997, the Standard Cash Consideration with respect to PAS
  Shares will be increased at a rate equal to 9% per annum from and including
  the first anniversary date to but excluding the Closing Date; or
 
                                      66
<PAGE>
 
    (b) the right to receive (subject to proration, as applicable) New PAS
  Common Stock in an amount equal to one share of New PAS Common Stock (the
  "Stock Consideration"); or
 
    (c) the right to receive (subject to proration, as applicable) the
  Standard Cash Consideration.
 
  The number of shares of New PAS Common Stock and the amount of cash
distributed with respect to elections for the Stock Consideration and/or the
Standard Cash Consideration may be limited under certain circumstances.
However, the number of shares of New PAS Common Stock and the amount of cash
distributed to PanAmSat stockholders that elect to receive the Standard
Consideration on account of their PAS Shares will not in any way be affected
by such limits. See "--Elections by Holders of PAS Common Stock; Exchange of
Stock Certificates in the Merger."
 
  Treatment of Options for PAS Common Stock. Each holder of a then-outstanding
Option to purchase shares of PAS Ordinary Common Stock under the Stock Plan,
whether or not then exercisable, will, in settlement thereof, receive for each
share of PAS Ordinary Common Stock subject to such Option an amount (subject
to applicable withholding tax) in cash equal to the Option Consideration,
provided that with respect to any person subject to Section 16(b) of the
Exchange Act, any such amount shall be paid as soon as practicable after the
first date payment can be made without liability to such person under Section
16(b) of the Exchange Act. Upon receipt of the Option Consideration, each
Option will be canceled. The surrender of an Option to PanAmSat in exchange
for the Option Consideration will be deemed a release of all rights the holder
had in respect of such Option. Except as otherwise agreed to by the parties to
the Reorganization Agreement, the Stock Option Plans will terminate as of the
Effective Time and the provisions in any other plan, program or arrangement
providing for the issuance or grant of any interest in respect of the capital
stock of PanAmSat or any of its subsidiaries will be canceled.
 
  Fractional Shares. No fractional shares of New PAS Common Stock will be
issued in the Merger or the Univisa Contribution. In lieu of the issuance of
any such fractional shares, each holder of PAS Common Stock who otherwise
would be entitled to receive a fractional share of New PAS Common Stock
pursuant to the Merger or the Univisa Contribution will be paid a cash
adjustment in respect of any fractional share of New PAS Common Stock that
would otherwise be issuable, and the amount of such cash adjustment shall be
equal to the product of such fractional amount and the Standard Cash
Consideration.
 
  Transfer Restrictions. At or after the Effective Time, there will be no
transfers on the stock transfer books of PanAmSat of the certificates
representing PAS Common Stock (each, a "Stock Certificate") which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, certificates formerly representing any such Stock Certificates are
presented to the Surviving Corporation, they will be canceled and exchanged
for the consideration, if any, deliverable in respect thereof pursuant to the
Reorganization Agreement. Stock Certificates surrendered in exchange for
Merger Consideration by any person constituting an "affiliate" of PanAmSat for
purposes of Rule 145(c) under the Securities Act shall not be exchanged until
New PanAmSat has received a written agreement from such person not to transfer
shares of New PAS Common Stock in violation of Rule 145.
 
ELECTIONS BY HOLDERS OF PAS COMMON STOCK; EXCHANGE OF CERTIFICATES IN THE
MERGER
 
  Elections. Concurrently herewith, an election form (the "Election Form") is
being mailed to each person who is a record holder of PAS Shares on the Record
Date. Each such holder will have the right to submit an Election Form
specifying the number of shares of PAS Common Stock that such person desires
to have converted into the right to receive the Standard Consideration (a
"Standard Election"), the number of shares of PAS Common Stock that such
person desires to have converted into the right to receive the Stock
Consideration (a "Stock Election") and the number of shares of PAS Common
Stock that such person desires to have converted into the right to receive the
Cash Consideration (a "Cash Election"). All PAS Shares for which such an
election is not made will be deemed to have made the Standard Election. The
same procedure regarding the foregoing elections will be used to determine the
consideration to be paid to S Company in the Univisa Contribution. See "THE
UNIVISA CONTRIBUTION AGREEMENT." The number of shares of New PAS Common Stock
issued to PanAmSat stockholders that make an effective Stock Election and the
amount of cash distributed to New PanAmSat stockholders that make an effective
Cash Election may be subject to the proration procedures
 
                                      67
<PAGE>
 
described below. HOWEVER, THE NUMBER OF SHARES OF NEW PAS COMMON STOCK AND THE
AMOUNT OF CASH DISTRIBUTED TO PANAMSAT STOCKHOLDERS THAT MAKE AN EFFECTIVE
STANDARD ELECTION WILL NOT IN ANY WAY BE AFFECTED BY THE PRORATION PROCEDURES.
 
  The Reorganization Agreement requires that, prior to the Effective Time, HCI
must designate a bank or trust company reasonably acceptable to PanAmSat to
act as the exchange agent for purposes of paying the Merger Consideration (the
"Exchange Agent"). HCI has appointed Boston EquiServe, L.P. to serve as the
Exchange Agent. Concurrently herewith, the Exchange Agent mailed an Election
Form to each person who was a holder of record of PAS Shares immediately prior
to the Record Date (i) a letter of transmittal (the "Letter of Transmittal")
which specifies that delivery shall be effected, and risk of loss and title to
each Stock Certificate will pass, only upon delivery of such Stock
Certificates to the Exchange Agent, (ii) instructions for use in effecting the
surrender of such Stock Certificate in exchange for the Merger Consideration
with respect to the PAS Common Stock formerly represented thereby and (iii) an
Election Form providing for such holders to make the Standard Election, the
Stock Election or the Cash Election. An election will be valid only if a
properly completed and executed Election Form accompanied by the Stock
Certificate of the holder submitting such Election Form is received by the
Exchange Agent by 5:00 p.m. (Eastern Standard Time) on the day immediately
preceding the date of the Special Meeting, as the same may be postponed or
adjourned (the "Election Deadline"). Holders of all PAS Shares transferred
following the Record Date or for which an effective election has not been made
will be deemed to have made a Standard Election.
 
  HOLDERS OF PAS COMMON STOCK SHOULD NOT SEND ANY CERTIFICATES REPRESENTING
PAS COMMON STOCK WITH THE ENCLOSED PROXY CARD. CONCURRENTLY HEREWITH, AN
ELECTION FORM AND A LETTER OF TRANSMITTAL ARE BEING MAILED TO EACH PERSON WHO
IS A HOLDER OF OUTSTANDING PAS ORDINARY COMMON STOCK OR PAS CLASS A COMMON
STOCK ON THE RECORD DATE, AND UPON REQUEST TO THE EXCHANGE AGENT, WILL BE
MAILED TO EACH PERSON WHO BECOMES A HOLDER OR BENEFICIAL OWNER OF PAS ORDINARY
COMMON STOCK OR PAS CLASS A COMMON STOCK PRIOR TO THE ELECTION DEADLINE.
PANAMSAT STOCKHOLDERS SHOULD SEND CERTIFICATES REPRESENTING PAS ORDINARY
COMMON STOCK AND PAS CLASS A COMMON STOCK TO THE EXCHANGE AGENT ONLY AFTER
THEY RECEIVE, AND IN ACCORDANCE WITH, THE INSTRUCTIONS CONTAINED IN THE
ELECTION FORM AND LETTER OF TRANSMITTAL.
 
  As soon as practicable after the Election Deadline, the Exchange Agent will
determine the allocation of the cash and stock portions of the Merger
Consideration and shall notify New PanAmSat of its determination (the
"Allocation Determination"). Promptly after the Allocation Determination, New
PanAmSat will deposit (or cause to be deposited) with the Exchange Agent, for
the benefit of the holders of PAS Common Stock and S Company, (i) cash in an
amount sufficient to pay the aggregate cash portion of the Merger
Consideration and the cash consideration payable in connection with the
Univisa Contribution and (ii) certificates representing the shares of New PAS
Common Stock ("New PanAmSat Certificates") for exchange in accordance with the
Reorganization Agreement and the Univisa Contribution Agreement (the cash and
shares deposited are hereafter referred to as the "Exchange Fund"). Upon
surrender of a Stock Certificate, the holder of such Stock Certificate (or, S
Company, upon the consummation of the Univisa Contribution) will be entitled
to receive promptly after the Allocation Determination, in exchange therefor
(a) a certified or bank cashier's check in the amount equal to the cash, if
any, which such holder has the right to receive (including any cash in lieu of
fractional shares of New PAS Common Stock) pursuant to the Reorganization
Agreement and/or (b) a New PanAmSat Certificate representing the number of
shares of New PAS Common Stock, if any, which such holder has the right to
receive pursuant to the Reorganization Agreement, in each case less the amount
of any required withholding taxes. Until so surrendered, each Stock
Certificate will be deemed, from and after the Effective Time, to represent
only the right to receive the Merger Consideration with respect to the PAS
Shares formerly represented thereby.
 
 
                                      68
<PAGE>
 
  Proration of Cash Elections. The amount of cash distributed to PanAmSat
stockholders that make effective Cash Elections may be limited under certain
circumstances. The Reorganization Agreement provides that the aggregate amount
of cash to be paid in the Merger and pursuant to the Univisa Contribution
Agreement will not exceed the product of (x) $15 (plus any interest applicable
to the Standard Cash Consideration) and (y) the aggregate number of shares of
PAS Common Stock issued and outstanding immediately prior to the Effective
Time (the "Maximum Cash Amount"). In the event that the sum of (a) the
aggregate amount of cash represented by the Cash Elections under the
Reorganization Agreement and the Univisa Contribution Agreement and (b) the
product of the aggregate number of Dissenting Shares and the Standard Cash
Consideration (such sum, the "Requested Cash Amount") exceeds the Maximum Cash
Amount minus the aggregate amount of cash payable pursuant to Standard
Elections made or deemed to have been made (such difference, the "Cash Cap"),
each holder making (or deemed to make) a Cash Election under the
Reorganization Agreement and the Univisa Contribution Agreement will receive
(a) cash in an amount equal to the greater of (i) $15 (plus any interest
applicable to the Standard Cash Consideration) and (ii) the product of the
Standard Cash Consideration and a fraction, the numerator of which is the Cash
Cap and the denominator of which is the Requested Cash Amount (the "Prorated
Cash Amount") and (b) a number of shares of New PAS Common Stock equal to a
fraction, the numerator of which is equal to the Standard Cash Consideration
minus the Prorated Cash Amount and the denominator of which is the Standard
Cash Consideration. See "THE UNIVISA CONTRIBUTION AGREEMENT."
 
  Proration of Stock Elections. The number of shares of New PAS Common Stock
that may be issued pursuant to Stock Elections under the Reorganization
Agreement and the Univisa Contribution Agreement may be limited under certain
circumstances. The Reorganization Agreement provides that, at New PanAmSat's
option, in the event that the Requested Cash Amount is less than the Cash Cap,
each holder making a Stock Election will receive, at New PanAmSat's option,
for each share for which a Stock Election has been made, (i) not more than the
Stock Consideration and not less than a number of shares of New PAS Common
Stock equal to a fraction, the numerator of which is the product of the
aggregate number of shares of New PAS Common Stock represented by Stock
Elections and the Standard Cash Consideration (the "Requested Stock Amount")
minus the difference between the Cash Cap and the Requested Cash Amount, and
the denominator of which is the Requested Stock Amount (such whole or
fractional share, the "Prorated Stock Amount") and (ii) cash in an amount
equal to the product of the Standard Cash Consideration and one minus the
Prorated Stock Amount. As of the date of this Proxy Statement/Prospectus, New
PanAmSat has not determined whether it will limit the Requested Stock Amount.
 
  Certain Prorations of Excess Cash. In addition, the holders of PAS Class A
Common Stock and S Company have agreed between themselves, without affecting
the rights of the holders of the PAS Ordinary Common Stock, that to the extent
that $15 multiplied by the number of outstanding shares of PAS Common Stock
exceeds the sum of (x) one half ( 1/2) of the cash represented by the shares
of PAS Common Stock that make effective Cash Elections under the
Reorganization Agreement and the Univisa Contribution Agreement, plus (y) the
cash represented by shares of PAS Common Stock as to which Standard Elections
were effectively made under the Reorganization Agreement and the Univisa
Contribution Agreement ("Excess Cash"), then the first $30 million of such
Excess Cash (plus any interest as provided in the Reorganization Agreement)
that S Company would have been entitled to receive pursuant to the Univisa
Contribution Agreement shall instead be paid to the holders of PAS Class A
Common Stock, and S Company shall receive the second $30 million (plus any
interest as provided in the Reorganization Agreement) that holders of PAS
Class A Common Stock would have been entitled to receive pursuant to the
Reorganization Agreement. If cash is transferred from one holder to another,
then the number of shares of New PAS Common Stock equal to the additional cash
that was delivered divided by $30 will be transferred from the transferee of
such cash to the transferor of such cash.
 
  Value Unit Proration. The Univisa Contribution Agreement contemplates that
the Share Repurchase of 7.5 million shares of New PAS Common Stock in exchange
for $225 million will occur immediately after S Company receives the
consideration payable in exchange for the Univisa Contribution. The
Reorganization Agreement assures that 7.5 million shares will be available for
redemption under the Univisa Contribution
 
                                      69
<PAGE>
 
Agreement by providing that if, as a result of all elections and prorations,
7.5 million shares would not be available for repurchase pursuant to the
Univisa Contribution Agreement, then S Company's elections would be further
prorated to ensure that a minimum of 7.5 million shares of New PAS Common
Stock would be available for the Share Repurchase. See "THE UNIVISA
CONTRIBUTION AGREEMENT" and "THE DTH SALE."
 
  Unclaimed Amounts. Any portion of the Exchange Fund (including the proceeds
of any investments thereof and any shares of New PAS Common Stock) that
remains unclaimed by former stockholders of PanAmSat six months after the
Effective Time will be delivered to New PanAmSat. Thereafter, former
stockholders of PanAmSat will be entitled to look only to New PanAmSat for
payment of the consideration payable on account of the Merger, cash in lieu of
fractional shares and unpaid dividends and distribution on New PAS Common
Stock deliverable in respect of each share such stockholder holds as
determined pursuant to the Reorganization Agreement, in each case without any
interest thereon. None of HCI, its affiliates, PanAmSat, New PanAmSat, the
Exchange Agent or any other person will be liable to any former holder of PAS
Shares or shares of PAS Class B Common Stock for any amount properly delivered
to a public official pursuant to applicable abandoned property, escheat or
similar laws.
 
  An election to receive all cash in connection with the Reorganization may
result in the receipt of either all cash or, in the event that the aggregate
amount of all elections to receive cash exceeds $15 multiplied by the number
of shares of PAS Common Stock outstanding at the time of the Reorganization, a
combination of cash and shares of New PAS Common Stock. For example, in the
event that all cash is elected by all direct and indirect holders of PAS
Common Stock, each such holder will receive $15 in cash plus one half ( 1/2)
share of New PAS Common Stock on account of each share of PAS Common Stock
held directly or indirectly by such holder.
 
  An election to receive all stock in connection with the Reorganization may
result in the receipt of either all stock or, in the event that (i) the direct
and indirect holders of more than one half ( 1/2) of the number of shares of
PAS Common Stock outstanding at the time of the Reorganization elect to
receive stock on account of such shares and (ii) New PanAmSat exercises its
option to limit the number of additional shares of New PAS Common Stock to be
issued, a combination of cash and shares of New PAS Common Stock. For example,
in the event that all stock is elected by all direct and indirect holders of
PAS Common Stock and New PanAmSat exercises its option to limit the number of
additional shares of New PAS Common Stock to be issued, each such holder will
receive one half ( 1/2) share of New PAS Common Stock plus $15 in cash on
account of each share of PAS Common Stock held directly or indirectly by such
holder. An election to receive $15 in cash and one half ( 1/2) share of New
PAS Common Stock on account of each share of PAS Common Stock will not be
affected by the proration procedures.
 
  The impact of the elections on New PanAmSat will depend upon whether such
elections direct New PanAmSat to issue more stock or pay more cash. If more
stock is issued, less debt will be incurred by New PanAmSat, making it less
highly leveraged. If more cash is paid (up to the proration limits), New
PanAmSat will incur more indebtedness as a result of such payments.

limitations contained in any such representation or warranty and except that
the representation of HCI with respect to the Contributed Entities' Capital
Expenditures for Satellites Under Construction (as defined below) shall be
true and correct in all respects without regard to materiality), in each case
as of the date of the Reorganization Agreement and except for inaccuracies or
omissions having or reasonably likely to have, individually or in the
aggregate, an economic impact on Galaxy of less than $50 million (excluding
the representation of the Hughes' Parties with respect to Capital Expenditures

representation and warranty with respect to Capital Expenditures for
Satellites Under Construction shall not be considered a failure of this
condition, if any deficiency is cured by the Closing Date; (ii) each of the
Hughes Parties and HE shall have performed in all material respects (other
than the obligations of the Hughes Parties and HE with respect to the
establishment and maintenance of a closed accounting system, dispositions of
assets and the obligation of HCI and/or HE to add at least $575 million to the
Capital Expenditures for Satellites Under Construction account between June
30, 1996 through the Closing Date, which will be performed without regard to
materiality) all obligations required to be performed by it under the
Reorganization Agreement and the Related Agreements to which it is a party on
or before the Closing Date; notwithstanding the foregoing, the obligations of

denial or dismissal of any pending application for a Galaxy Permit that has
been filed with the FCC or (b) a loss, to the extent caused by or related to
(1) a mere delay in the receipt of revenue, as opposed to the cancellation or
modification of a contract, and the consequent loss of revenue related to such
delay or (2) the launch or in-orbit failure of any Galaxy satellite, to the
extent such loss is covered by insurance.
 
  Obligations of the Hughes Parties. The obligations of the Hughes Parties to
effect the transactions contemplated by the Reorganization Agreement are
subject to the satisfaction of the following conditions, any or all of which
may be waived in whole or in part by HCI: (i) each of the representations and
warranties of PanAmSat set forth in the Reorganization Agreement shall be true
and correct in all material respects (without regard to any materiality
limitations contained in any such representation or warranty) as of the date
of the Reorganization Agreement, except for inaccuracies or omissions having
or reasonably likely to have, individually or in the aggregate, an economic
impact on PanAmSat and its subsidiaries taken as a whole of less than $50
million; (ii) PanAmSat shall have performed in all material respects all
obligations required to be performed by it under the Reorganization Agreement
and the related agreements to which it is a party on or before the Closing
Date; notwithstanding the foregoing, the obligations of HCI to effect the

relieved by the failure of the foregoing condition if such failure is the
result, directly or indirectly, of any breach by any Hughes Party of any of
its material obligations under the Reorganization Agreement; (iii) no material
adverse change shall have occurred since September 20, 1996 with respect to
PanAmSat having or reasonably likely to have, individually or in the

following shall be deemed to be a "change": (a) the loss, denial or dismissal
of any pending application for a PAS Permit that has been filed with the FCC
or (b) a loss, to the extent caused by or related to (1) a mere delay in the
receipt of revenue, as opposed to the cancellation or modification of a
contract, and the consequent
 
                                      72
<PAGE>
 
loss of revenue related to such delay or (2) the launch or in-orbit failure of
any PanAmSat satellite, to the extent such loss is covered by insurance, but
provided further that the parties have agreed that the Comsat Litigation and
any possible exposure in respect thereof may be evaluated in connection with a
determination of whether a material adverse change has occurred
notwithstanding the fact that the Comsat Litigation is disclosed in the
schedules to the Reorganization Agreement; (iv) PanAmSat shall have delivered
to HCI written evidence of the agreement by each holder of Options to
terminate such Options on or before the Effective Time; (v) PanAmSat shall
have delivered to HCI evidence satisfactory to HCI that PanAmSat will, as of
the Closing Date, terminate all of its obligations under the Original MOU (as

(vi) PanAmSat shall have delivered to HCI a letter of resignation from each
person that is a director of PanAmSat immediately prior to the Closing, which
resignation shall be effective as of the Effective Time.

securities in respect of shares of common stock outstanding or (b) amend,
waive or otherwise modify any of the terms of any option, warrant or stock
option plan; (iv) neither PanAmSat nor any of the Contributed Entities will
amend or propose to amend their respective articles of incorporation or
bylaws; (v) neither PanAmSat nor any of the Contributed Entities will, subject
to certain exceptions, (a) acquire or agree to acquire any satellite or other
spacecraft which it has not previously agreed in writing to acquire, or (b)
except as otherwise required, make one or more investments or capital
expenditures exceeding $35 million in the aggregate in any twelve-month period
for all such investments or expenditures that occur from September 20, 1996;
provided, however, that (1) PanAmSat or any Contributed Entity may replace any
satellite lost in a launch or in orbit, and (2) PanAmSat may continue existing
capital programs (plus additional expenses solely for change orders of up to
10% of the progress payments on each satellite remaining to be paid as of the
date of the Reorganization Agreement) and purchase such terrestrial equipment
as necessary to supply customers in the ordinary course in connection with
leases of transponder capacity by such customers; and provided further, that
PanAmSat shall not make additional investments in, or make any capital
expenditures for the benefit of, any business engaged in DTH services unless
ancillary to the sale or lease of, or other provision of services or capacity
via, transponders; (vi) neither PanAmSat nor any of the Contributed Entities
will sell, pledge, lease, dispose of or encumber any of its assets other than
in the ordinary course of business consistent with past practice; (vii)
neither PanAmSat nor any of the Contributed Entities will authorize,
recommend, propose or announce an intention to adopt a plan of complete or
partial liquidation or dissolution; (viii) neither PanAmSat nor any of the
Hughes Parties will take any action that results in any of their respective
representations or warranties being untrue in any material respect or any of
their respective covenants or any other conditions to the Asset Contribution,
the Univisa Contribution or the Merger not being satisfied in all material
respects; (ix) neither PanAmSat nor any of the Contributed Entities will,
subject to certain exceptions, assume, incur or pre-pay any indebtedness or
guarantee any such indebtedness or issue or sell any
 
                                      73
<PAGE>
 
debt securities or warrants or rights to acquire any debt securities or
guarantee any such indebtedness or enter into any lease other than in the
ordinary course, or create any mortgages, liens, security interests or other
encumbrances on their property in connection with any indebtedness thereof, or
enter into any keepwell or other agreements to maintain the financial
condition of another person; (x) neither PanAmSat nor any of the Contributed
Entities will, subject to certain exceptions and other than in the ordinary
course of business consistent with past practice, enter into, materially
modify or amend any of the terms or provisions of any material contract, other
than in the ordinary course of business consistent with past practice; (xi)
neither PanAmSat nor any of the Contributed Entities will take any action,
other than in the ordinary course of business, consistent with past practice
or as required by the Commission or by law, to effect any material change in
any of its current accounting policies, procedures and practices; (xii)
neither PanAmSat nor any of the Contributed Entities will pay, discharge or
satisfy any material claims, liabilities or obligations other than in the
ordinary course of business and consistent with past practice; (xiii) neither
PanAmSat nor any of the Contributed Entities will waive any rights of
substantial value or make any payment, direct or indirect, of any material
liability before the same comes due, except to the extent to which fair value
is received in exchange for such waiver or payment; (xiv) neither PanAmSat nor
any of the Contributed Entities will fail to maintain its existing insurance
coverage; (xv) neither PanAmSat nor any of the Contributed Entities will
engage in any transaction, agreement or understanding with, directly or
indirectly, any of such entity's affiliates (as defined in Rule 12b-2 under
the Exchange Act) which involves the transfer of consideration or has a
financial impact on such entity, other than pursuant to existing agreements
which are done on terms that the respective board of directors determines in
good faith to be equal to, or more favorable than, the terms that could be
obtained from third parties in similar transactions and/or for similar goods
or services or which are otherwise permitted; (xvi) except for Permits which
lapse or expire due to ordinary course changes in the business of PanAmSat or
Galaxy, and subject to certain other exceptions, neither PanAmSat nor Galaxy
will surrender or fail to renew or extend any of the Permits issued to them by
the FCC (other than those related to PanAmSat or Galaxy ground stations) or
give the FCC or other government entity with jurisdiction any grounds to
institute any proceeding for the revocation, suspension or adverse
modification of any PAS Permit, or Galaxy Permit, issued by the FCC; (xvii)
each of the Contributed Entities and PanAmSat will, subject to certain
exceptions, use commercially reasonable efforts to maintain each material FCC
construction Permit until the applicable construction projects are complete
and will use commercially reasonable efforts to avoid having certain permits
dismissed or denied; (xviii) each of the Contributed Entities and PanAmSat
will use commercially reasonable efforts to protect the transmissions to and
from PanAmSat's satellites and ground stations and to and from Galaxy's
satellites and ground stations from interference from other radio
communications facilities (existing or proposed) to the extent such
interference is prohibited by FCC rules or rights accorded to such satellites
under the ITU's Radio Regulations and shall promptly notify the other party of
any actual or threatened interference; and (xix) subject to certain
exceptions, neither PanAmSat nor the Contributed Entities will enter into any
contract, agreement or other instrument that (a) does not expire by the later
of one year after the date of the Reorganization Agreement or six months after
the Closing Date or (b) is not subject to termination upon less than six
months' written notice to the other party thereto, which in either case
materially restricts or limits its right to conduct business or compete.
 
  In addition to the foregoing and subject to certain exceptions, PanAmSat and
HCI also have agreed that none of PanAmSat, its subsidiaries or the
Contributed Entities will, during the Interim Period: (i) increase any
compensation or fringe benefits of any of its directors, officers, or key
employees; (ii) pay or agree to pay any pension, retirement allowance,
severance, termination or other employee benefit not required or contemplated
by any of its existing benefit plans to any such director, officer or key
employee, whether past or present; (iii) enter into any new, or materially
amend any existing, employment or severance or termination agreement with any
such director, officer or key employee (other than with respect to new hires
consistent with past practice); or (iv) establish, adopt, enter into or amend
any collective bargaining, bonus, profit sharing, thrift, compensation, stock
option, restricted stock, pension, retirement, savings, welfare, deferred
compensation, employment, termination, severance or other employee benefit
plan, agreement, trust, fund, policy or arrangement for the benefit or welfare
of any directors, officers or current or former employees, except in each case
(a) to the extent required by applicable law or regulation, (b) pursuant to
existing collective bargaining agreements, (c) in the case of PanAmSat and its
subsidiaries only, for cash bonuses in lieu of options not to exceed $5
million in the
 
                                      74
<PAGE>
 
aggregate, (d) normal bonuses and normal increases to officers and key
employees consistent with past practice or other agreements which PanAmSat and
HCI believe are necessary for the continued conduct of their respective
business in the ordinary course, or (e) for amendments to its existing
benefits plans which were disclosed to the other parties prior to the
execution of the Reorganization Agreement or which would not materially
increase the cost of benefits to PanAmSat and its subsidiaries, taken as a
whole, or to the Galaxy Business, as the case may be. During the Interim
Period, control of the operations of PanAmSat and its subsidiaries will remain
with PanAmSat and control of the Galaxy Business will remain with HCI and the
Contributed Entities. No action will be taken constituting an assignment or
transfer of control of an FCC permit requiring the consent of the FCC without
first obtaining such consent or approval.
 
  Subject to certain exceptions, New PanAmSat has agreed that during the
Interim Period it will conduct no operations and will preserve intact its
business organization. In addition, subject to certain exceptions, New
PanAmSat will not, prior to the Closing Date, without the prior written
consent of PanAmSat: (i) amend its certificate of incorporation or bylaws
(other than as contemplated by the Reorganization Agreement); (ii) issue,
pledge or sell additional shares of capital stock of any class or securities
convertible into capital stock of any class, or any rights, warrants or
options to acquire any convertible securities or capital stock, or any other
securities in respect of, in lieu of, or in substitution for, shares of common
stock outstanding on September 20, 1996; (iii) declare any dividend or other
distribution in respect of any class or series of its capital stock; (iv)
authorize, recommend, propose or announce an intention to adopt a plan of
complete or partial liquidation or dissolution; (v) take any action that would
make any representation or warranty of the Hughes Parties contained in the
Reorganization Agreement inaccurate in any respect at, or as of any time prior
to, the Closing Date; or (vi) enter into a contract, commitment or arrangement
to do any of the foregoing, or to authorize, recommend, propose or announce an
intention to do any of the foregoing.
 
  The parties to the Reorganization Agreement have also agreed: (i) to provide
each other during the Interim Period with reasonable access to information
about their respective businesses, other than competitively sensitive
information such as pricing or customer specific information; (ii) to treat as
confidential each other's confidential information; (iii) to cooperate in
preparing filings in connection with obtaining any necessary regulatory
approvals, including FCC consent, to the transactions contemplated by the
Reorganization Agreement; (iv) to give notice to each other of certain events;
(v) to consult with each other as to any press releases or public
announcements relating to the Reorganization Agreement or the transactions
contemplated thereby; (vi) that PanAmSat will deliver to HCI a letter
identifying, to the best of PanAmSat's knowledge, all persons whom PanAmSat
expects will be deemed to be affiliates of PanAmSat for purposes of Rule 145
under the Securities Act; (vii) that New PanAmSat will prepare and submit to
the NYSE or the Nasdaq a listing application covering the shares of New PAS
Common Stock issuable in the Merger; (viii) that, on or prior to the Closing
Date, each Contributed Entity shall enter into written agreements to document
all previously undocumented arrangements with Affiliates of the Contributed
Entities for material goods or services provided to the Galaxy Business; (ix)
that promptly following the Closing, New PanAmSat will enter into a customary
agreement to pay and indemnify HE for obligations arising under existing
guarantees provided by HE of leveraged leases of transponders used in the
Galaxy Business; (x) to supplement their respective schedules delivered in
connection with the Reorganization Agreement as of the Closing Date to the
extent necessary to reflect matters permitted by, or consented to by, the
other parties or as may be necessary to make the schedules accurate and
complete in all material respects as of the Closing Date; (xi) subject to the
fulfillment at or before the Closing Date of each of the conditions of
performance set forth in the Reorganization Agreement or the waiver thereof,
to perform such further acts and execute such documents as may be reasonably
required to effect the transactions contemplated by the Reorganization
Agreement; (xii) to enter into and take all actions necessary to consummate
the transactions contemplated by each of the Related Agreements to which they
are a party, subject in each case to the terms and conditions of each such
Related Agreement; and (xiii) to cooperate in the preparation of this Proxy
Statement/Prospectus and the related Registration Statement pertaining to the
shares of New PAS Common Stock issuable in connection with the Merger.
 
  Pursuant to the Reorganization Agreement, HCI shall cause one of the
Contributed Entities to acquire a leasehold interest, for a term of at least
30 years and otherwise on commercially reasonable terms and conditions, in and
to the real property on which are located the ground station and other
improvements currently owned by HCSS located off
 
                                      75
<PAGE>
 
East Garton Road in Castle Rock, Colorado. In addition, such lease shall
provide that any domestic or international satellite arc shall not be blocked
by any improvement or structure on any adjoining land owned or controlled by
HCSS, its successors and assigns. HCI shall cause one of the Contributed
Entities to continue to negotiate, on commercially reasonable terms, for the
acquisition of the fee interest of Texaco Exploration and Production, Inc. in
and to approximately 752 acres located off Telegraph Road in Fillmore,
California.
 
  The Reorganization Agreement further provides that, as of July 1, 1996, the
Galaxy Business will operate as a separate stand-alone entity with respect to
all aspects of its cash management including retention of the cash receipts
and proceeds from all sources of the business together with the payment of all
necessary operating expenses of the business (excluding noncash outlays for
expenses such as depreciation and amortization) and capital outlays (including
those expenses and capital outlays that are directly attributable to the
business but which may, for convenience purposes, be paid by HE and
redistributed to the Galaxy Business) (the "Closed System"). The Galaxy
Business also will be responsible for the payment of all properly allocated
costs of the Galaxy Business, including its allocated share of corporate and
sector "General & Administrative" costs consistent with the past accounting
practices of the Galaxy Business. The Galaxy Business will compute an income
tax provision for the taxable earnings of the business in accordance with GAAP
and will provide for the appropriate income taxes of the business including
the determination and recognition of necessary deferred tax amounts (which
deferred tax amounts may not be deducted as cash expenses). In addition, HCI
will cause all proceeds received during the Interim Period from any source
with respect to the disposition of any asset or group of assets disposed of in
related transactions valued in excess of $60,000 (other than for satellites
under construction) included in the Galaxy Business to be separately
identified and retained within the Closed System. The aforementioned practices
will constitute a Closed System of cash management. HCI will be required to
use cash proceeds retained in the business to fund additions to its Capital
Expenditures for Satellites Under Construction accounts. For purposes of the
Reorganization Agreement, "Capital Expenditures for Satellites Under
Construction" includes manufacturing, launch and launch insurance, progress
payments and capitalized interest amounts. HCI, with the assistance of HE,
will continue to manage and pursue its capital expenditures program for the
construction and development of satellites during the period from July 1, 1996
through the Closing Date as it deems necessary in the ordinary course of its
business and consistent with prudent business practices. To the extent that
additions to HCI's Capital Expenditures for Satellites Under Construction
accounts, as determined on a consistent basis and in accordance with GAAP and
HCI's historical accounting practices and procedures, during the period from
July 1, 1996 through the Closing of the Merger, do not equal or exceed $575
million in the aggregate, HE shall be obligated to contribute any difference
in cash at the Closing. At Closing, the Galaxy Business will not participate
in any cash management programs of HE and New PanAmSat will operate as an
independent company.
 
NON-SOLICITATION
 
  Under the Reorganization Agreement, PanAmSat agreed that it will not, and
will not permit its subsidiaries to, directly or indirectly, enter into,
solicit, initiate or continue any discussions or negotiations with, or
encourage or respond to any inquiries or proposals by, or participate in any
negotiations with, or provide any information to, or otherwise cooperate in
any other way with, any corporation, partnership, person or other entity or
group (each, a "Person") (other than HCI, HCG or any of their affiliates or
representatives), concerning any offer or proposal which constitutes or is
reasonably likely to lead to any Acquisition Proposal (as defined below);
provided that the PanAmSat Board may, in the event of an unsolicited
Acquisition Proposal, engage in negotiations or discussions with, or provide
information or data to, any Person relating to an Acquisition Proposal if (x)
the Acquisition Proposal is a bona fide fully-financed written offer submitted
to the PanAmSat Board and, after consulting with a nationally recognized
investment bank, the PanAmSat Board determines that such Acquisition Proposal
is economically superior to the transactions contemplated by the
Reorganization Agreement and the related agreements (a "Superior Acquisition
Proposal"), and (y) the PanAmSat Board determines, after having received the
written opinion of outside legal counsel to PanAmSat, that the failure to
engage in such negotiations or discussions or provide such information would
result in a breach of the fiduciary duties of the PanAmSat Board under
applicable law. Then, in such event, the PanAmSat Board may withdraw or modify
its approval or recommendation of the Merger or the Reorganization Agreement,
approve or recommend the
 
                                      76
<PAGE>
 
Superior Acquisition Proposal or terminate the Reorganization Agreement. HCI
shall have the right to match any such Superior Acquisition Proposal and to
have such matching proposal immediately accepted by PanAmSat, for five
business days after HCI is informed of the necessary determinations with
respect to such Superior Acquisition Proposal. Any information furnished to
any Person in connection with an Acquisition Proposal shall be provided
pursuant to a confidentiality agreement in customary form on terms not more
favorable to such Person than the terms contained in the Confidentiality
Agreement dated as of July 19, 1996 between PanAmSat and HE. Subject to all of
the foregoing requirements, PanAmSat will immediately notify HCI orally and in
writing if any discussions or negotiations are sought to be initiated, any
inquiry or proposal is made or any information is requested by any Person with
respect to any actual or potential Acquisition Proposal, and immediately
notify HCI of all material terms of any proposal which it may receive in
respect of any such Acquisition Proposal (as defined below), including the
identity of the Person making the Acquisition Proposal or the request for
information, if known, and thereafter shall inform HCI on a timely, ongoing
basis of the status and content of any discussions or negotiations with such a
third party, including immediately reporting any material changes to the terms
and conditions thereof. PanAmSat will, and will cause its subsidiaries and
affiliates to and will use its best efforts to ensure that their respective
officers, directors, employees, investment bankers, attorneys, accountants and
other agents, immediately cease and cause to be terminated all discussions and
negotiations that have taken place prior to the date of the Reorganization
Agreement, if any, with any Persons conducted heretofore with respect to any
Acquisition Proposal. As used in the Reorganization Agreement, "Acquisition
Proposal" means any of the following (other than the transactions contemplated
by the Reorganization Agreement) involving PanAmSat or any of its
subsidiaries: (i) any merger, consolidation, share exchange, recapitalization,
business combination, or other similar transaction; (ii) any sale, lease
exchange, mortgage, pledge, transfer or other disposition of 10% or more of
the assets of PanAmSat and its subsidiaries, taken as a whole, in a single
transaction or series of transactions; (iii) any tender offer or exchange for
or other purchase of 10% or more of the outstanding shares of the capital
stock of PanAmSat or the filing of a registration statement under the
Securities Act in connection therewith; or (iv) any public announcement of a
proposal, plan or intention to do any of the foregoing. Nothing contained in
the foregoing summary shall prohibit PanAmSat or the PanAmSat Board from
taking and disclosing to its stockholders a position with respect to a tender
offer by a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under
the Exchange Act or making such disclosure as may be required by applicable
law. Note, however, that subject to certain exceptions, under the Principal
Stockholders Agreement, stockholders controlling over 98% of the vote have
agreed to use their reasonable efforts to remove any member of the PanAmSat
Board that fails to submit the Merger to the stockholders for their approval.
See "OTHER AGREEMENTS--Principal Stockholders Agreement."
 
STANDSTILL AGREEMENT
 
  The Reorganization Agreement provides that for five years following the
Closing, none of the Hughes Parties or their affiliates shall acquire, or come
to hold, beneficially or otherwise, whether by purchase, exchange or
otherwise, individually or in the aggregate, more than 81% of the outstanding
equity interests in New PanAmSat, except (i) pursuant to a merger which is
approved by the holders of a majority of the shares of New PAS Common Stock
not owned directly or indirectly by HE or any of its affiliates, (ii) pursuant
to a tender offer recommended by the Disinterested Directors (as defined
below) of New PanAmSat and a second-step merger which offers the same per
share consideration to all holders of New PAS Common Stock and in which more
than one half of the outstanding New PAS Common Stock not owned by HCI and its
affiliates at the inception of the transaction is either tendered or voted in
favor of the transaction, and (iii) except pursuant to such other transaction
as shall provide for equal treatment of holders of New PAS Common Stock and is
approved by the holders of a majority of the shares of New PAS Common Stock
not owned by HCI and its affiliates and by a majority of the Disinterested
Directors of New PanAmSat. For purposes of the Reorganization Agreement
"Disinterested Director" means a director of New PanAmSat that is not an
existing or retired employee of New PanAmSat or any of its affiliates.
 
INDEMNIFICATION
 
  Indemnification and Insurance for Directors and Officers. The Reorganization
Agreement provides that, from and after the Closing Date, all rights to
indemnification existing on September 20, 1996 in favor of individuals who at
or prior to the Closing Date were directors or officers of any of the
Contributed Entities, New
 
                                      77
<PAGE>
 
PanAmSat, PanAmSat or any of their respective subsidiaries, as set forth in
their respective organizational documents, will survive the Merger, the
Univisa Contribution and the Asset Contribution with respect to matters
existing or occurring at or prior to the Closing Date and shall continue in
full force and effect for a period of five years following the Closing Date.
Each of HCI, the Contributed Entities, New PanAmSat, and PanAmSat will, and
from and after the Closing Date, New PanAmSat will indemnify, defend and hold
harmless each person who was on September 20, 1996, or has been at any time
prior to September 20, 1996 or who becomes prior to the Closing Date, an
officer or director of HCI, any Contributed Entity, New PanAmSat or PanAmSat,
or any of their respective subsidiaries (each individually an "Indemnified
Person" and, collectively, the "Indemnified Persons") against all losses,
claims, damages, costs, expenses (including attorneys' fees and expenses),
liabilities or judgments or amounts that are paid in settlement with the
approval of the Indemnified Person (which approval shall not be unreasonably
withheld) as a result of, or in connection with, any threatened or actual
claim, action, suit, proceeding or investigation based in whole or in part on,
or arising in whole or in part out of, the fact that such person is or was a
director or officer of HCI, any Contributed Entity, New PanAmSat or PanAmSat,
or any of their respective subsidiaries or out of or in connection with
activities in such capacity, whether pertaining to any matter existing or
occurring at or prior to the Closing Date and whether asserted or claimed
prior to, at or after the Closing Date ("Indemnified Liabilities"), including
all Indemnified Liabilities based in whole or in part on, or arising in whole
or in part out of, or pertaining to the Reorganization Agreement or the
transactions contemplated by the Reorganization Agreement, in each case to the
full extent a corporation is permitted under the corporate law of the state in
which it is incorporated to indemnify any such person and, without limiting
the generality or effect of the foregoing, to the fullest extent provided in
the respective organizational documents of HCI, the Contributed Entities, New
PanAmSat and PanAmSat and their respective subsidiaries as in effect on
September 20, 1996. New PanAmSat will pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Person to the
fullest extent permitted by law. In the event any such claim, action, suit,
proceeding or investigation is brought against any Indemnified Persons
(whether arising before or after the Closing Date), (i) the Indemnified
Persons may retain counsel reasonably satisfactory to HCI or PanAmSat, or from
and after the Closing, New PanAmSat and HCI or PanAmSat will, or from and
after the Closing, New PanAmSat will pay all fees and expenses of such counsel
for the Indemnified Persons promptly as statements therefore are received and
(ii) HCI or PanAmSat shall, or from and after the Closing, New PanAmSat will,
use all reasonable efforts to assist in the vigorous defense of any such
matter, provided that none of HCI or PanAmSat, or from and after the Closing,
New PanAmSat, will be liable for any settlement effected without its prior
written consent, which consent will not unreasonably be withheld. Any
Indemnified Party wishing to claim indemnification under this section, upon
learning of any such claim, action, suit, proceeding or investigation, shall
notify HCI or PanAmSat, or from and after the Closing, New PanAmSat (but the
failure so to notify shall not relieve a party from any liability which it may
have under this section except and only to the extent such failure materially
prejudices such party), and shall deliver to HCI or PanAmSat, or from and
after the Closing, New PanAmSat, any undertaking contemplated or required by
the corporate law of its state in which it is incorporated. The Indemnified
Persons as a group may retain only one law firm to represent them with respect
to each such matter unless there is, in the opinion of counsel to an
Indemnified Person, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of any two or more
Indemnified Persons or unless different defenses may exist. Each of HCI, the
Contributed Entities, New PanAmSat and PanAmSat agree that all rights to
indemnification, including provisions relating to advances of expenses
incurred in defense of any action or suit, existing in favor of the
Indemnified Persons with respect to matters occurring through the Closing
Date, will survive the Asset Contribution, the Univisa Contribution and the
Merger and will continue in full force and effect for a period of not less
than four years from the Closing Date; provided, however, that all rights to
indemnification in respect of any Indemnified Liabilities asserted or made
within such period will continue until the disposition of such Indemnified
Liabilities.
 
  For a period of five years after the Closing Date, New PanAmSat will
maintain in effect or replace with equivalent policies of directors' and
officers' liability insurance as maintained by HCI, the Contributed Entities,
New PanAmSat or PanAmSat, as the case may be, and their respective
subsidiaries with respect to matters arising before the Closing Date, provided
that New PanAmSat will not be required to pay an annual premium for such
 
                                      78
<PAGE>
 
insurance in excess of 175% of the last annual premium paid by HCI, a
Contributed Entity, New PanAmSat or PanAmSat, as the case may be, prior to
September 20, 1996, but in such case will purchase as much coverage as
possible for such amount.
 
  Indemnification for Excluded and Contributed Liabilities. Pursuant to the
Reorganization Agreement, HCI agrees to indemnify, defend and hold harmless
New PanAmSat and each of its subsidiaries and their respective successors-in-
interest against any losses, claims, damages or liabilities, joint or several,
arising out of or in connection with any loss, claim, damage or liability
against or pertaining to any Hughes Party and/or their Affiliates (other than
New PanAmSat and its subsidiaries) other than the Galaxy Liabilities, and HCI
shall reimburse New PanAmSat, each such subsidiary and each such successor-in-
interest (each, a "New PanAmSat Indemnified Party") for any legal or any other
expenses reasonably incurred by any of them in connection with investigating
or defending any such loss, claim, damage or liability.
 
  New PanAmSat agrees to indemnify, defend and hold harmless each of HCI and
HCG and their subsidiaries and successors-in-interest after the Closing
against any losses, claims, damages or liabilities, joint or several, arising
out of or in connection with the Galaxy Liabilities assumed by New PanAmSat
pursuant to the terms of the Reorganization Agreement, and New PanAmSat shall
reimburse HCI or HCG, as the case may be, and each of their subsidiaries and
each such successor-in-interest (each, a "Hughes Indemnified Party") for any
legal or any other expenses reasonably incurred by any of them in connection
with investigating or defending any such loss, claim, damage, liability or
action.
 
  Whenever any claim shall arise for indemnification as described above, the
New PanAmSat Indemnified Party or the Hughes Indemnified Party, as the case
may be (in either case, an "Indemnified Party"), shall promptly notify the
other party providing such indemnification (an "Indemnifying Party") in
writing of such claim and, when known, the facts constituting the basis for
such claim. Failure by any Indemnified Party to so notify the Indemnifying
Party shall not relieve such Indemnifying Party of any liability hereunder
except to the extent that such failure materially prejudices such Indemnifying
Party.
 
  After receipt of the foregoing notice, if the Indemnifying Party undertakes
to defend any such claim, then the Indemnifying Party shall be entitled, if it
so elects, to take control of the defense and investigation with respect to
such claim and to employ and engage attorneys of its own choice to handle and
defend the same, at the Indemnifying Party's cost, risk and expense, upon
written notice to the Indemnified Party of such election, which notice
acknowledges such Indemnifying Party's obligation to provide indemnification
hereunder. The Indemnifying Party shall not settle any third-party claim that
is the subject of indemnification without the written consent of the
Indemnified Party, which consent shall not be unreasonably withheld; provided,
however, that the Indemnifying Party may settle a claim without the
Indemnified Party's consent if such settlement (i) makes no admission or
acknowledgment of liability or culpability with respect to such Indemnified
Party, (ii) includes a complete release of the Indemnified Party and (iii)
does not require the Indemnified Party to make any payment or forego or take
any action. The Indemnified Party shall cooperate in all reasonable respects
with the Indemnifying Party and its attorneys in the investigation, trial and
defense of any lawsuit or action with respect to such claim and any appeal
arising therefrom. The Indemnified Party may, at its own cost, participate in
any investigation, trial and defense of such lawsuit or action controlled by
the Indemnifying Party and any appeal arising therefrom. If, after receipt of
notice described in the preceding paragraph, the Indemnifying Party does not
undertake to defend any such claim, the Indemnified Party may, but shall have
no obligation to, contest any lawsuit or action with respect to such claim and
the Indemnifying Party shall be bound by the result obtained with respect
thereto by the Indemnified Party (including, without limitation, the
settlement thereof without the consent of the Indemnifying Party). If there
are one or more legal defenses available to the Indemnified Party that
conflict with those available to the Indemnifying Party, the Indemnified Party
shall have the right, at the expense of the Indemnifying Party, to assume the
defense of the lawsuit or action; provided, however, that the Indemnified
Party may not settle such lawsuit or action without the consent of the
Indemnifying Party, which consent shall not be unreasonably withheld.
 
  At any time after the commencement of a defense of any lawsuit or action,
the Indemnifying Party may request the Indemnified Party to agree in writing
to the abandonment of such contest or to the payment or compromise by the
Indemnifying Party of such claim, whereupon such action shall be taken unless
the
 
                                      79
<PAGE>
 
Indemnified Party determines that the contest should be continued and so
notifies the Indemnifying Party in writing within 15 days of receipt of such
request from the Indemnifying Party. If the Indemnified Party determines that
the contest should be continued, the Indemnifying Party shall be liable only
to the extent of the lesser of (i) the amount which the other parties to the
contested claim had agreed to accept in payment or compromise as of the time
the Indemnifying Party made its request therefor to the Indemnified Party or
(ii) such amount for which the Indemnifying Party may be liable with respect
to such claim by reason of the provisions of the Reorganization Agreement.
 
CERTAIN BENEFITS MATTERS
 
  The Reorganization Agreement provides that, unless otherwise agreed to by
PanAmSat and HE, New PanAmSat shall establish, as of the Effective Time, a
defined contribution pension plan (the "New PanAmSat Savings Plan") which
shall be qualified under Sections 401(a) and (k) of the Code and a trust
related thereto which shall be exempt from taxation under Section 501(a) of
the Code. The New PanAmSat Savings Plan shall provide for employee deferrals
and employer matching contributions at the rate of 4% of compensation, with
employer matching contributions made in stock of New PanAmSat. To the extent
permitted by law, credit for past service with the Galaxy Business or PanAmSat
prior to the Effective Time shall be provided under the New PanAmSat Savings
Plan to participants for the purpose of vesting and eligibility to
participate.
 
  New PanAmSat shall provide stock options to certain employees from and after
the time that New PanAmSat's stock is publicly held. The New PanAmSat Board
will act upon the recommendations of a joint committee of representatives of
PanAmSat and HCI with regard to such stock options.
 
TERMINATION
 
  The Reorganization Agreement is subject to termination by mutual consent of
HCI and PanAmSat or at the option of either PanAmSat or HCI if the Merger, the
Univisa Contribution and the Asset Contribution are not consummated on or
before December 20, 1997 (the "Final Date"), provided that such right to
terminate will not be available to any party whose failure to fulfill any
obligation under the Reorganization Agreement has been the cause of or
resulted in the failure of the Asset Contribution, the Univisa Contribution or
the Merger to occur on or before such date, provided further that the non-
breaching party will have the right to proceed with the Reorganization in such
case. In addition, prior to such time, the Reorganization Agreement is subject
to termination upon: (i) a breach of any representation, warranty, covenant or
agreement by either party, or if any representation or warranty shall have
become materially inaccurate or incomplete, in either case, such that the
conditions to Closing could not be satisfied, provided that willful or
reckless breaches shall be deemed to cause the conditions to Closing to become
incapable of fulfillment; (ii) the issuance of any permanent, final and non-
appealable injunction or order of a court or other competent authority
preventing the consummation of any of the Asset Contribution, the Univisa
Contribution or the Merger; or (iii) failure to receive the requisite vote for
approval and adoption by the PanAmSat stockholders for the Reorganization
Agreement and the Merger.
 
  In addition to the foregoing termination events, the Reorganization
Agreement may be terminated by HCI at any time prior to the Closing Date if
(i) the PanAmSat Board withdraws, modifies or changes its recommendation of
the Reorganization Agreement in any manner adverse to HCI or resolves to do
any of the foregoing, (ii) the PanAmSat Board recommends to its stockholders
any Acquisition Proposal, or (iii) a tender offer or exchange offer for 15% or
more of the outstanding PAS Common Stock is commenced, and the PanAmSat Board
recommends that the holders of such stock tender their shares in such tender
or exchange offer. See "--Termination Fee."
 
  The Reorganization Agreement also may be terminated by the PanAmSat Board at
any time prior to the Closing Date if in the exercise of its good faith
judgment as to fiduciary duties owed to its stockholders imposed by law, and
provided that the PanAmSat Board shall have complied with each of the other
requirements set forth in the Reorganization Agreement with respect to
alternative proposals, the PanAmSat Board adopts a Superior Acquisition
Proposal.
 
 
                                      80
<PAGE>
 
TERMINATION FEE
 
  PanAmSat has agreed that, in the event that the Reorganization Agreement
shall be terminated as a result of (i) the failure to consummate the Merger,
the Univisa Contribution and the Asset Contribution prior to the Final Date
when (A) an Acquisition Proposal has been made but not rejected by PanAmSat
and (B) PanAmSat or any of its subsidiaries or stockholders shall thereafter
consummate or agree to consummate a transaction that would constitute an
Acquisition Proposal with any person within twelve (12) months from the date
of such termination, (ii) PanAmSat's stockholders have failed to approve the
Reorganization Agreement and the Merger and an Acquisition Proposal has been
made and not withdrawn or rejected, or (iii) action of the PanAmSat Board (A)
to withdraw, modify or change its recommendation of the Reorganization
Agreement in a manner adverse to the Hughes Parties, (B) to recommend to the
PanAmSat stockholders any Acquisition Proposal, or (C) a tender offer or
exchange offer for 15% or more of the outstanding shares of PAS Common Stock
is commenced and the PanAmSat Board recommends that the holders of stock
tender their shares in such tender or exchange offer, or (iv) if in the
exercise of its good faith judgment as to fiduciary duties of the PanAmSat
Board owed to its stockholders imposed by law, the PanAmSat Board adopts a
Superior Acquisition Proposal, then PanAmSat shall pay to HCI $80 million (the
"Termination Fee"). The Termination Fee is payable in the case of termination
under clause (i) described above at the earlier of the signing of a definitive
agreement relating to such Acquisition Proposal or at the closing of such
Acquisition Proposal, and within one business day of termination described in
clauses (ii), (iii) and (iv) above. If a Termination Fee is payable by
PanAmSat, PanAmSat also shall assume and concurrently pay or reimburse HCI for
all reasonable fees and expenses (the "Expenses") incurred by HCI and its
affiliates (including the fees and expenses of their counsel, accountants,
financial advisors and funding sources) related to the matters contemplated by
the Reorganization Agreement and the Related Agreements, up to $7.5 million in
the aggregate. If PanAmSat fails to pay the Termination Fee or the Expenses
when due, PanAmSat shall also pay to HCI all costs and expenses (including
fees and disbursements of counsel) incurred in collecting such overdue
amounts, together with interest on such overdue amounts from the date such
payment was required to be made until the date such payment is received at a
rate per annum equal to the "reference rate" as announced from time to time by
Bank of America NT&SA.
 
CERTAIN RELATED PARTY TRANSACTIONS
 
  Pursuant to the Reorganization Agreement, in the enforcement, interpretation
or amendment of the Reorganization Agreement and the related agreements by New
PanAmSat affecting the rights and obligations of HE or its affiliates
following the Closing, New PanAmSat will be represented by a committee of the
New PanAmSat Board comprised of Disinterested Directors. See "DESCRIPTION OF
NEW PANAMSAT CAPITAL STOCK."
 
EXPENSES
 
  Whether or not the Reorganization is consummated, each party will pay its
own expenses in connection with the transactions contemplated by the
Reorganization Agreement, except that (i) the filing fees in connection with
filings under the HSR Act, (ii) the filing fee in connection with the filing
of this Proxy Statement/Prospectus or the Registration Statement with the
Commission, (iii) the filing fees in connection with necessary applications to
the FCC and similar foreign agencies, (iv) the expenses incurred in connection
with the printing and mailing of the Registration Statement and the Proxy
Statement/Prospectus and (v) fees and expenses related to any expert
consultants (excluding attorneys and accountants) retained in connection with
certain regulatory filings will be shared equally by the Hughes Parties, on
the one hand, and PanAmSat, on the other hand.
 
AMENDMENT
 
  Subject to applicable law, the Reorganization Agreement may be amended,
modified and supplemented, whether before or after the vote of the
stockholders of PanAmSat contemplated hereby, by written agreement of the
parties thereto, at any time prior to the Closing Date; provided, however,
that after the approval of the Merger and the Reorganization Agreement by the
stockholders of PanAmSat, no such amendment or modification may reduce or
change the consideration to be received by the stockholders of PanAmSat in the
Merger.

                      THE UNIVISA CONTRIBUTION AGREEMENT
 
  The following is a summary of certain provisions of the Univisa Contribution
Agreement, a copy of which is attached hereto as Appendix C and incorporated
herein by reference. The following summary is qualified by reference to the
complete text of the Univisa Contribution Agreement.
 
  Concurrently with the execution of the Reorganization Agreement, HCI, New
PanAmSat, Televisa and S Company entered into the Univisa Contribution
Agreement pursuant to which S Company agreed to contribute to New PanAmSat all
of the outstanding capital stock of Univisa, which is the indirect owner of
all outstanding shares of PAS Class B Common Stock.
 
  The Univisa Contribution. The Univisa Contribution Agreement provides that
on the Closing Date (immediately after the Asset Contribution and immediately
before the Merger), S Company will contribute to New PanAmSat all of the
outstanding shares of capital stock of Univisa. In exchange for such
contribution, S Company will receive consideration with an aggregate value
deemed by the parties as of the date of the Univisa Contribution Agreement to
be equal to the product of $30 multiplied by the number of shares of PAS Class
B Common Stock indirectly owned by S Company (the "Value Unit Consideration"),
which shall be divided into units with a deemed value of $30 each (each such
unit, a "Value Unit"), each such Value Unit to be exchanged, at the election
of S Company, for one of the following:
 
    (i) the right to receive the Standard Consideration (consisting of an
  amount in cash equal to one half ( 1/2) of the Standard Cash Consideration
  plus one half ( 1/2) share of New PAS Common Stock); or
 
    (ii) the right to receive the Stock Consideration (consisting of one (1)
  share of New PAS Common Stock); or
 
    (iii) the right to receive the Standard Cash Consideration (consisting of
  an amount in cash equal to $30, plus any interest that accrues pursuant to
  the Reorganization Agreement if the Closing has not occurred on or prior to
  September 20, 1997).
 
S Company's election to receive the Stock Consideration or the Standard Cash
Consideration in exchange for Value Units shall be subject to adjustment in
accordance with the proration procedures specified in the Reorganization
Agreement. See "THE REORGANIZATION AGREEMENT--Elections by Holders of PAS
Common Stock; Exchange of Certificates in the Merger." At the time that the
Value Unit Consideration is paid, a portion of such consideration equal to the
Trust Holdback (as defined below) will be assigned and delivered to a trustee
to be selected by New PanAmSat, HCI, S Company and Televisa, to be held in
trust to satisfy certain indemnification obligations of S Company and
Televisa. See "--Indemnification." As a result of the Univisa Contribution,
Univisa will become a wholly owned subsidiary of New PanAmSat. Thereafter, New
PanAmSat will indirectly own all of the outstanding shares of PAS Class B
Common Stock, which shall remain outstanding after the Merger as Class B
Common Stock of the Surviving Corporation.
 
  Repurchase of Shares and Purchase of DTH Option. Immediately after S Company
receives the consideration payable in exchange for the Univisa Contribution,
New PanAmSat will repurchase 7.5 million shares of New PAS Common Stock
received by S Company in exchange for $225 million. Following the Share
Repurchase, either Televisa, S Company and/or their designees will purchase
the DTH Options for $225 million. See "THE DTH SALE."
 
  Certain Representations and Warranties. The Univisa Contribution Agreement
contains customary representations and warranties by each of Televisa, S
Company, HCI and New PanAmSat as to due organization, good standing and
corporate authority, capital structure (with respect to Televisa and S
Company), enforceability of the Univisa Contribution Agreement, no violations
of its charter, bylaws or material agreements, and the absence of government
and third party consents required to consummate the Univisa Contribution. The
Univisa Contribution Agreement contains additional representations and
warranties as to, among other things, the preparation of Univisa's financial
statements in accordance with United States generally accepted accounting
 
                                      82
<PAGE>
 
principles, the preparation of Televisa's financial statements in accordance
with Mexican generally accepted accounting principles, and the tax returns
filed and taxes paid (or reserved for) by Univisa and its subsidiaries. Each
of HCI and New PanAmSat also has represented and warranted that it has no plan
or intention to liquidate (completely or partially) or dissolve Univisa or
USHI, or merge, consolidate or combine either of them with or into New
PanAmSat, PanAmSat or any other entity, other than a merger of USHI into
Univisa qualifying as a tax free liquidation for Federal income tax purposes,
and it has no plan or intention to cause or permit Univisa, USHI or PanAmSat
to take any of the foregoing actions.
 
  Certain Covenants. Pursuant to the Univisa Contribution Agreement, each of
Televisa and S Company has agreed, among other things, that during the Interim
Period: (i) neither Univisa nor any of its subsidiaries will engage in any new
business activities; (ii) Univisa and its subsidiaries shall pay, discharge
and satisfy all direct and indirect liabilities, indebtedness or other
obligations that become due on or before the Closing Date; (iii) on or prior
to the Closing Date, Univisa and its subsidiaries shall distribute to
Televisa, S Company and their designees all assets of Univisa and its
subsidiaries (other than shares of USHI stock, shares of PAS Class B Common
Stock and cash sufficient to pay all liabilities and expenses, including
taxes, incurred by Univisa or USHI in connection with the transactions
contemplated by the Univisa Contribution Agreement (that are the
responsibility of Univisa) which are not paid prior to the Closing Date); and
(iv) Televisa and S Company will assume any and all liabilities of Univisa and
USHI relating to occurrences or events prior to or through the last date on
which transactions contemplated by the Univisa Contribution Agreement and the
Reorganization Agreement are consummated relating to the assets transferred
out of Univisa or USHI. Each of Televisa, S Company, HCI and New PanAmSat has
agreed that, during the Interim Period, none of them will take or permit any
of their subsidiaries to take any action that results in any condition to
Closing not being satisfied in all material respects. The parties to the
Univisa Contribution Agreement also have agreed to certain other customary
covenants regarding access to Univisa's properties, books and records,
cooperation in the preparation of filings to obtain any required governmental
approvals, providing notice of certain events and consulting with each other
as to press releases or public announcements. In addition, Univisa is required
to change the names of "Univisa, Inc." and "Univisa Satellite Holdings, Inc."
to names that do not include "Univisa" prior to the Closing Date, and to
cooperate in preparing a Known Liabilities Estimate (as such term is defined
in the Univisa Contribution Agreement) of the amount reasonably necessary to
satisfy in full all of the liabilities of each of Univisa and USHI estimated
or projected as of the Closing Date together with the amount reasonably
necessary to satisfy all taxes for all taxable years and other periods ending
on the Closing Date, including any such taxes attributable to any
distributions of assets by Univisa made in contemplation of the transactions
contemplated by the Univisa Contribution Agreement.
 
  Conditions to the Univisa Contribution. The obligations of the parties to
consummate the Univisa Contribution are subject to the satisfaction on or
prior to the Closing Date of the following conditions, any or all of which may
be waived in whole or in part by the party benefiting thereby: (i) no order,
rule or statute by a government entity restricting or prohibiting the Univisa
Contribution shall have been issued or entered which would materially restrict
or prevent consummation of the Univisa Contribution; (ii) the waiting period
under the HSR Act or any related action shall have expired or been terminated
or withdrawn; (iii) all necessary governmental approvals shall have been
obtained; (iv) PanAmSat's Certificate of Incorporation shall have been amended
so that the consummation of the Univisa Contribution will not cause shares of
PAS Class B Common Stock to be converted or exchanged into any other shares of
the capital stock of PanAmSat; (v) all of the conditions to the obligations of
HCI (in the case of HCI and New PanAmSat) and PanAmSat (in the case of
Televisa and S Company) under the Reorganization Agreement shall have been
satisfied or waived; (vi) each of certain representations and warranties set
forth in the Univisa Contribution Agreement shall be true and correct in all
material respects as of the date of the Univisa Contribution Agreement and
(except to the extent such representations or warranties speak as of an
earlier date) as of the Closing Date; (vii) each of the parties shall have
performed in all material respects all obligations required to be performed by
it under the Univisa Contribution Agreement on or before the Closing Date,
provided that the failure of the foregoing condition shall not relieve the
party relying on such condition of its obligations under the Univisa
Contribution Agreement if such failure is the result, directly or indirectly,
of any breach by such party of any of its material obligations
 
                                      83

Univisa Contribution Agreement (the "Collateral Agreements").
 
  Agreement to Maintain Existing Capital Structure. For a period of two years
from the Closing Date, neither HCI nor New PanAmSat shall, and neither shall

partially), dissolve, merge, consolidate or combine Univisa or USHI with or

(partially or completely), dissolve, merge, consolidate or combine PanAmSat

<PAGE>
 
or PanAmSat to consummate) certain corporate transactions involving Univisa,
USHI, PanAmSat, New PanAmSat or other entities, certain changes to the capital
structure of PanAmSat and certain stock transfers involving shares of capital
stock of PanAmSat, or (d) any other transaction consummated after the Closing

million cash, (y) cash or cash equivalents in the amount of the Damages for
which Televisa and S Company are obligated to indemnify as described in this

respective affiliates, subsidiaries, representatives, successors and assignees
from and against any Damages incurred in connection with any breach or
inaccuracy of any representation or warranty, or breach of any covenant, made
by HCI or New PanAmSat in the Univisa Contribution Agreement.
 
  Termination. The Univisa Contribution Agreement is subject to termination by

the terminating party is not in material breach of its obligations under the
Univisa Contribution Agreement; (ii) the conditions to the terminating party's
obligations under the Univisa Contribution Agreement have not been complied

breached any of its material representations, warranties or covenants without
curing such non-compliance or non-performance; (iii) any injunction or order
of a court or other competent authority preventing the consummation of the
Univisa Contribution shall have become permanent, final and non-appealable; or
(iv) for any reason the Reorganization Agreement is terminated, except that S
Company shall not be able to terminate if the Reorganization Agreement is
terminated because PanAmSat's stockholders fail to approve and adopt the
Merger and the Reorganization Agreement or the PanAmSat Board takes or fails
to take certain action with respect to its recommendation of the
Reorganization Agreement.
 
  Expenses. Whether or not the Univisa Contribution is consummated, each party
will pay its own expenses in connection with the transactions contemplated by

disbursements of their certified public accountants, and their out-of-pocket
expenses (including all out-of-pocket expenses incurred by them or any of
their subsidiaries in complying with the covenant by HCI and New PanAmSat not
to take certain corporate actions with respect to Univisa or USHI for two
years following the Closing Date), in each case to the extent all such
expenses are incurred incident to the preparation of the Univisa Contribution
Agreement and the consummation of the transactions contemplated thereby, and
the aggregate amount of all such expenses does not exceed $500,000.

                                 THE DTH SALE
 
BACKGROUND
 
  On March 27, 1995, PanAmSat and Televisa entered into a DTH System in Latin
America Memorandum of Understanding (the "Original MOU") evidencing their
intent to form various joint ventures to provide DTH services in Latin America
(the "Latin America JVs").
 
  In November 1995, PanAmSat announced that it would serve as a satellite
provider for the Latin America DTH service to be offered by Globo
Participacoes, Ltd. ("Globo"), Televisa, News Corp. and Tele-Communications
International, Inc. ("TCI"). On February 29, 1996, PanAmSat, Televisa, Globo
and News Corp. entered into a letter agreement (as subsequently amended, the
"1996 Letter Agreement") pursuant to which PanAmSat agreed to provide service
to the Latin America JVs on 48 transponders ultimately on PAS-5 and PAS-6,
with temporary service on PAS-3 pending the commencement of service on PAS-6.
Under the 1996 Letter Agreement, Globo, Televisa and News Corp. agreed to
proportionally guaranty 100% of PanAmSat's fees for transponder services
provided to the Latin America JVs.
 
  The Original MOU was terminated and superseded on September 20, 1996 by the
Revised DTH System in Latin America Memorandum of Understanding (the "Revised
MOU"), except with respect to the guaranty obligations described above.
Pursuant to the Revised MOU and certain oral agreements with Televisa,
PanAmSat has certain options to purchase equity interests in certain Televisa-
controlled entities that would take equity interests in the Latin America JVs
and companies formed to sell DTH services to consumers in Latin America. In
addition, the Revised MOU provides that with respect to the matters described
therein, all prior written or oral agreements and understandings related
thereto are terminated, other than an indemnification agreement between
Televisa and PanAmSat dated January 22, 1996 relating to certain agreements
between PanAmSat and Irdeto, B.V., which survives the Revised MOU.
 
  PanAmSat and Televisa also have an oral agreement in principle that grants
to PanAmSat certain options to purchase equity interests in a joint venture to
offer DTH services in Spain (the "Spain Joint Venture") that would have the
capacity to broadcast approximately 24-80 digital channels to subscribers in
Spain using small 24-36 inch (60-90 cm) antennas.
 
  An HCI affiliate is an investor in Galaxy Latin America ("GLA"), a
partnership that provides DTH services in Latin America. During the
negotiation of the Merger, HCI made it a condition to the Reorganization that
PanAmSat divest itself of the DTH Options. See "THE REORGANIZATION--Background
of the Reorganization," and "THE REORGANIZATION AGREEMENT--Conditions to the
Reorganization." Accordingly, on September 20, 1996, PanAmSat, Televisa and S
Company entered into the DTH Option Purchase Agreement, pursuant to which
either Televisa, S Company and/or their designees will acquire PanAmSat's
interests in the Latin America JVs and the Spain Joint Venture. The DTH Option
Purchase Agreement has no effect on the 1996 Letter Agreement and does not
terminate or alter any agreements regarding PanAmSat's provision of
transponder services to the Latin America JVs.
 
  On August 16, 1996, the members of the DTH Committee of the PanAmSat Board
(comprised of directors unaffiliated with Televisa) engaged Salomon Brothers
to represent it in connection with the sale of the DTH Options. Given that the
interest of PanAmSat in the DTH Options is held derivatively through Televisa
and that Televisa-controlled entities would be equity participants in the
Latin America JVs and the Spain Joint Venture, it was determined that Televisa
would be the appropriate party to purchase the DTH Options. After
negotiations, it was agreed that either Televisa, S Company and/or their
designees would purchase the DTH Options for $225 million. Televisa required
that the purchase be made with stock of New PanAmSat, and the 1993 Indentures
require that, in connection with any sale of PanAmSat assets, at least 85% of
the proceeds be paid in cash. As a result, the parties agreed to the following
structure: immediately after New PanAmSat's payment of consideration to S
Company in the Univisa Contribution, New PanAmSat will repurchase 7.5 million
shares of the New PAS Common Stock received by S Company pursuant to the
Univisa Contribution for $225 million, and then either Televisa, S Company
and/or their designees will purchase the DTH Options for $225 million. See
"THE REORGANIZATION--Background of the Reorganization."
 
 
                                      86
<PAGE>
 
  In a separate transaction, on September 20, 1996, PanAmSat agreed to provide
Televisa, S.A. de C.V., a wholly owned subsidiary of Televisa ("Televisa
Spain"), with transponder service from five PAS-3 Ku-band transponders, at
least three of which will be for the delivery of television services to Spain,
which may include DTH services. The transponder service fees reflect market
rates. This agreement is unaffected by the DTH Sale.
 
  As a result of the DTH Sale, PanAmSat will no longer have options to acquire
any equity interests in the Latin America JVs and the Spain Joint Venture.
Notwithstanding the foregoing, the 1996 Letter Agreement will remain in effect
with respect to 36 transponders. The Brazil Transponder Agreement has since
been entered into for 12 of the transponders originally covered by the 1996
Letter Agreement. Accordingly, PanAmSat will provide transponder service to
the Latin America JVs pursuant to the 1996 Letter Agreement and the Brazil
Transponder Agreement. See "BUSINESS OF PANAMSAT--Customers and Markets."
 
TERMS OF THE DTH OPTION PURCHASE AGREEMENT
 
  The following is a summary of certain provisions of the DTH Option Purchase
Agreement, a copy of which is attached hereto as Appendix H and incorporated
herein by reference. The following summary is qualified by reference to the
complete text of the DTH Option Purchase Agreement.
 
  The DTH Option Purchase Agreement provides that PanAmSat will sell the DTH
Options (which are comprised of PanAmSat's rights to purchase equity interests
in the Latin America JVs and the Spain Joint Venture), at Televisa's option,
to Televisa and/or its designees or, under certain circumstances, at S
Company's option, to S Company and/or its designees, for a purchase price of
$225 million. The closing of the DTH Sale will occur substantially
concurrently with the receipt by S Company of the consideration to be paid by
New PanAmSat to it in connection with the Univisa Contribution.
 
  Pursuant to the DTH Option Purchase Agreement, the parties have made certain
representations and warranties to each other, as to, among other things (i)
corporate power and authority to execute and deliver the DTH Option Purchase
Agreement and to effect the transactions contemplated thereby, (ii) due
authorization by all necessary corporate action, (iii) due execution and
delivery of the DTH Option Purchase Agreement and enforceability of the DTH
Option Purchase Agreement and (iv) required governmental consents. The parties
have also agreed to cooperate and endeavor in good faith to take all actions
required in connection with the consummation of the transactions contemplated
by the DTH Option Purchase Agreement.
 
  The DTH Option Purchase Agreement may be terminated at any time prior to the
closing thereof (the "DTH Termination Date") if the Reorganization Agreement
is terminated. Notwithstanding such a termination, Televisa may extend the DTH
Option Purchase Agreement for a period of up to 12 months after the DTH
Termination Date (the "Extension Period") by giving written notice to PanAmSat
within the Extension Period. If the DTH Option Purchase Agreement is so
extended, the purchase price shall be increased at the rate of 10% per annum.
If PanAmSat enters into an agreement to effect a business combination within
the Extension Period and if Televisa has committed to purchase the DTH Options
in connection with such business combination, the closing of the DTH Options
shall be adjourned, at Televisa's option, until the consummation of such
business combination.
 
OPINION OF PANAMSAT'S FINANCIAL ADVISOR REGARDING THE DTH SALE
 
  On September 19, 1996, Salomon Brothers delivered its written opinion (the
"Salomon Brothers Opinion") to the PanAmSat Board that, as of such date, and
based upon and subject to the qualifications described below, the
consideration to be paid by Televisa to acquire the DTH Options represented
fair value for the DTH Options from a financial point of view.
 
  A copy of the Salomon Brothers Opinion is attached hereto as Appendix E.
Stockholders of PanAmSat are urged to read the Salomon Brothers Opinion in its
entirety for information with respect to the procedures followed, assumptions
made, matters considered and limits of the review by Salomon Brothers in
rendering the Salomon Brothers Opinion. References herein to the Salomon
Brothers Opinion are qualified by reference to the full text of the Salomon
Brothers Opinion, which is incorporated herein by reference.
 
 
                                      87
<PAGE>
 
  In connection with rendering the Salomon Brothers Opinion, Salomon Brothers
reviewed certain publicly available information concerning PanAmSat and
certain other financial information concerning PanAmSat, the Latin America JVs
and the Spain Joint Venture, including financial forecasts, that were provided
to Salomon Brothers by PanAmSat and Televisa. Salomon Brothers discussed the
business operations and financial condition of the Latin America JVs and the
Spain Joint Venture, as well as other matters Salomon Brothers believed to be
relevant to its inquiry, with certain officers and employees of PanAmSat and
Televisa. Salomon Brothers also considered such other information, financial
studies, analyses, investigations and financial, economic and market criteria
that it deemed relevant.
 
  In its review and analysis and in arriving at its opinion, Salomon Brothers
assumed and relied upon the accuracy and completeness of the financial and
other information reviewed by it, and Salomon Brothers did not assume any
responsibility for independent verification of such information. With respect
to the financial forecasts relating to the Latin America JVs and the Spain
Joint Venture, Salomon Brothers assumed that such financial forecasts had been
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the management of the Latin America JVs and the Spain Joint
Venture as to the future financial performance of the Latin America JVs and
the Spain Joint Venture, and Salomon Brothers expressed no opinion with
respect to such forecasts or the assumptions on which they were based. Salomon
Brothers did not make or obtain or assume any responsibility for making or
obtaining any independent evaluations or appraisals of any of the assets
(including properties and facilities) or liabilities of the Latin America JVs
and the Spain Joint Venture. Salomon Brothers was not asked to, and did not,
solicit other proposals for the acquisition of the DTH Options. No limitations
were imposed by PanAmSat with respect to the Salomon Brothers Opinion.
 
  The Salomon Brothers Opinion is necessarily based upon conditions as they
existed as of the date of such opinion. The Salomon Brothers Opinion does not
address PanAmSat's underlying business decision to sell the DTH Options to any
party, including Televisa, in connection with the Merger. The Salomon Brothers
Opinion does not address the fairness of the Merger. The Salomon Brothers
Opinion is directed only to the consideration to be paid by Televisa to
acquire the DTH Options and does not constitute a recommendation concerning
how any stockholder of PanAmSat should vote with respect to the Merger.
 
  Based upon the terms of Salomon Brothers' engagement, the Salomon Brothers
Opinion is intended solely for the benefit and use of PanAmSat (including its
management, directors and attorneys) in considering the sale of the DTH
Options. Salomon Brothers was retained by PanAmSat solely as an advisor to
PanAmSat, and not as an advisor to or agent of any other person, and
PanAmSat's engagement of Salomon Brothers was not intended to confer rights
upon any such other person (including any stockholder, employee or creditor of
PanAmSat) as against Salomon Brothers, Salomon Brothers' affiliates or their
respective directors, officers, agents and employees.
 
  Salomon Brothers has acted as financial advisor to PanAmSat and will receive
a fee for its services. Pursuant to an engagement letter dated August 16,
1996, PanAmSat has agreed to pay Salomon Brothers for the rendering of the
Salomon Brothers Opinion a cash fee of $900,000, of which $400,000 will be
payable upon consummation of the sale of the DTH Options. PanAmSat has also
agreed to (i) reimburse Salomon Brothers for certain out-of-pocket expenses
incurred by Salomon Brothers in connection with its services and (ii)
indemnify Salomon Brothers and certain related persons against certain
liabilities, including liabilities under the federal securities law, relating
to or arising out of its engagement by or services to PanAmSat. In the
ordinary course of business, Salomon Brothers may actively trade the
securities of PanAmSat, Televisa and General Motors (including its GMH
"targeted stock") for Salomon Brothers' own account and for the accounts of
its customers and, accordingly, may at any time hold a long or short position
in such securities.
 
  Salomon Brothers is an internationally recognized investment banking firm
that provides financial services in connection with a wide range of business
transactions. As part of its business, Salomon Brothers regularly engages in
the valuation of companies and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and for
other purposes. PanAmSat retained Salomon Brothers based on Salomon Brothers'
expertise in the valuation of companies as well as its familiarity with the
telecommunications industry.

                               OTHER AGREEMENTS
 
  The following is a summary of certain provisions of the Assurance Agreement,
Principal Stockholders Agreement, Stockholder Agreement, Registration Rights
Agreement and Tax Agreement, copies of which are attached hereto as Appendices
K, L, M, N and O and incorporated herein by reference. The following summaries
are qualified by reference to the complete text of such agreements.
 
ASSURANCE AGREEMENT
 
  Contemporaneously with the execution of the Reorganization Agreement, HE
entered into the Assurance Agreement for the benefit of PanAmSat, S Company
and New PanAmSat, pursuant to which HE made assurances with respect to certain
obligations of HE's subsidiaries under the Reorganization Agreement and the
Univisa Contribution Agreement. The Assurance Agreement requires HE to loan or
arrange for a third party to loan to New PanAmSat, on or before the Closing
Date, $1.725 billion (plus any interest that accrues pursuant to the
Reorganization Agreement and Univisa Contribution Agreement) to pay the cash
consideration in the Merger and the Univisa Contribution and to fund the Share
Repurchase. This obligation is conditioned upon the satisfaction of all of the
conditions to the obligations of HCI and the entities currently comprising the
Galaxy Business to effect the Reorganization pursuant to the Reorganization
Agreement. If the loan is funded by a third party, HE is not required to
provide a guarantee or credit enhancement of such loan and, if the loan is
provided by HE, it shall be on commercially reasonably terms. HE has
determined that it will loan the $1.725 billion to New PanAmSat pursuant to
the terms of the New Financing that will be fully negotiated prior to Closing.
See "THE REORGANIZATION--Financing in Connection with the Reorganization."
 
  The Assurance Agreement also provides that HE will cause its subsidiaries
(i) to operate the Galaxy Business in a manner consistent with its operations
prior to September 20, 1996, and (ii) to perform their respective obligations
under such agreements.
 
  HE is obligated under the Assurance Agreement to take certain other
affirmative actions: HE will continue, after the Closing Date, to provide a
guaranty of New PanAmSat's obligations under all leveraged leases of Galaxy
transponders that were entered into prior to September 20, 1996, and HE will
cause its subsidiaries to negotiate and enter into a non-exclusive, royalty-
free, perpetual cross-license with New PanAmSat with respect to intellectual
property of HE that is used in the Galaxy Business prior to the Closing Date
and intellectual property of Galaxy that is used by HE prior to the Closing
Date.
 
PRINCIPAL STOCKHOLDERS AGREEMENT
 
  Voting of Shares. Concurrently with the execution of the Reorganization
Agreement, the Principal Stockholders entered into the Principal Stockholders
Agreement pursuant to which each Principal Stockholder has agreed that, at any
meeting (whether annual or special and whether or not an adjourned or
postponed meeting) of the holders of PAS Common Stock, however called, or in
connection with any written consent of the holders of PAS Common Stock, such
Principal Stockholder will vote (or cause to be voted) the shares of PAS
Common Stock held of record or beneficially owned by such Principal
Stockholder (i) in favor of the Merger, the Reorganization Agreement and the
approval and adoption of the terms thereof and each of the other actions
contemplated by the Reorganization Agreement and the Principal Stockholders
Agreement; (ii) against any Acquisition Proposal and against any action or
agreement that would result in a breach in any respect of any covenant,
representation or warranty or any other obligation or agreement under the
Reorganization Agreement, the Univisa Contribution Agreement or the Principal
Stockholders Agreement; and (iii) against the following actions (other than
pursuant to the terms of the Principal Stockholders Agreement, the
Reorganization Agreement or the Univisa Contribution Agreement): (A) any
extraordinary corporate transaction, such as a merger, consolidation or other
business combination involving PanAmSat or its subsidiaries; (B) any sale,
lease or transfer by PanAmSat of a material amount of assets (including stock)
of PanAmSat or its subsidiaries, or a reorganization, restructuring,
recapitalization, special dividend, dissolution or liquidation of PanAmSat or
its subsidiaries; or (C) (1) any change in a majority of the persons who
constitute the board of directors of PanAmSat or its subsidiaries, including
any proposal to sell a substantial equity interest in PanAmSat or its
subsidiaries; (2) any change in the present capitalization of PanAmSat
including any proposal to sell a substantial
 
                                      89
<PAGE>
 
equity interest in PanAmSat and its subsidiaries; (3) any amendment of
PanAmSat's or any of its subsidiaries' charters or bylaws; (4) any other
change in PanAmSat's or any of its subsidiaries' corporate structure or
business; or (5) any other action which is intended, or could reasonably be
expected, to impede, interfere with, delay, postpone, or materially adversely
affect the Merger and the transactions contemplated by the Principal
Stockholders Agreement, the Reorganization Agreement and the Univisa
Contribution Agreement. Each Principal Stockholder also has agreed (a) not to
enter into any agreement or understanding that would be inconsistent with the
provisions of the Principal Stockholders Agreement and (b) to take certain
actions intended to cause the transactions contemplated by the Reorganization
Agreement to be approved by PanAmSat's stockholders, if the PanAmSat Board has
failed or refused (other than as a result of a breach by HCI or any of its
affiliates under the Reorganization Agreement or because HCI and its
affiliates will not be able to satisfy the conditions precedent thereto) to
submit the transactions contemplated by the Reorganization Agreement to the
holders of PAS Common Stock.
 
  Limitation on Transfer of Shares. Pursuant to the Principal Stockholders
Agreement, the Principal Stockholders have also agreed that they will not: (i)
sell, transfer or pledge any or all of their shares of PAS Common Stock or any
interest therein (or enter into any agreement or consent to do the same),
except for certain limited sales and transfers specified in the Principal
Stockholders Agreement and provided that a Principal Stockholder may pledge
its shares in connection with bona fide loan transactions with institutional
lenders if the terms of such pledge satisfy certain conditions; (ii) grant any
proxies or powers of attorney, deposit the shares into a voting trust or enter
into a voting agreement with respect to their shares of PAS Common Stock,
except that a Principal Stockholder may deposit its shares into a voting trust
or enter into a voting agreement in connection with any loan from an
institutional lender if certain conditions are satisfied; or (iii) take any
action that would be in contravention of the Principal Stockholders Agreement
or result in a breach by PanAmSat of its obligations under the Reorganization
Agreement.
 
  Permitted sales and transfers under the Principal Stockholders Agreement are
limited to, for each of S Company, on the one hand, and the Class A Holders as
a group, on the other hand, sales of up to an aggregate of 2,500,000 shares of
PAS Common Stock (up to an aggregate of 5,000,000 shares collectively),
provided that such amounts may be increased to up to 5,000,000 shares each (or
10,000,000 shares collectively) upon the mutual agreement between S Company
and the Class A Holders, and provided further that except in the case of
transfers pursuant to Rule 144 or a registered public offering, any shares so
transferred convert to PAS Ordinary Common Stock and the transferee of such
shares becomes a party to the Principal Stockholders Agreement and agrees not
to make an Acquisition Proposal and not to dissent in the Merger. Each
Principal Stockholder has further agreed that it will not transfer any shares
of PAS Common Stock during a period of up to 30 days prior to the Closing Date
commencing on such date as HCI shall notify the Principal Stockholders to
cease transfers pursuant to this sentence.
 
  No Solicitation. The Principal Stockholders Agreement requires that none of
the Principal Stockholders will, nor will they permit any of their respective
subsidiaries, or any of its or their officers, directors, employees, agents of
their affiliates (including any investment banker, attorney or accountant
retained by any Principal Stockholder) to, directly or indirectly, enter into,
solicit, initiate, or continue any discussions or negotiations with, or
encourage or respond to any inquiries or proposals by, or participate in any
negotiations with, or provide any information to, or otherwise cooperate in
any other way with, any person or group, other than HCI, HCG and their
affiliates, concerning any Acquisition Proposal. Each of the Principal
Stockholders is obligated to immediately notify HCI and HCG if any discussions
or negotiations are sought to be initiated, any inquiry or proposal is made,
or any information is requested with respect to any Acquisition Proposal, and
must notify HCI and HCG of the terms it receives regarding any such
Acquisition Proposal, including the identity of the prospective purchaser or
soliciting party if known. Each of the Principal Stockholders has further
agreed to use its best efforts as a stockholder of PanAmSat to cause PanAmSat
not to solicit any inquiries or any proposal which constitutes, or may
reasonably be expected to lead to, an Acquisition Proposal. Nothing contained
in the provisions described above will prohibit any director of PanAmSat from
taking actions in his or her capacity as such which are permitted or required
under the Reorganization Agreement.
 
                                      90
<PAGE>
 
  Stockholder Termination Fee. The Principal Stockholders Agreement further
provides that in the event that the Reorganization Agreement is terminated and
a Termination Fee is payable by PanAmSat to HCI pursuant to the Reorganization
Agreement, then each of the Principal Stockholders will be obligated to pay to
HCI an amount equal to (x) the number of shares of PAS Common Stock
beneficially owned by such Principal Stockholder on September 20, 1996,
multiplied by (y) the excess of (i) the per share value of consideration paid
or payable in consequence of consummation of the Acquisition Proposal over
(ii) $30.
 
STOCKHOLDER AGREEMENT
 
  On the Closing Date, the Minority Stockholders, HCI and New PanAmSat will
enter into the Stockholder Agreement, pursuant to which the parties thereto
will agree to (i) certain restrictions on the purchase and sale of shares of
New PAS Common Stock, (ii) the designation of directors to the New PanAmSat
Board and (iii) certain covenants not to compete.
 
  Tag-Along Right. The Stockholder Agreement will provide that each Minority
Stockholder will have the right to participate on a "tag-along" basis in any
proposed disposition by HCI or its affiliates (other than New PanAmSat) of
more than 5% of the then-outstanding shares of New PAS Common Stock. A
Minority Stockholder may participate in any such disposition by selling the
number of its shares of New PAS Common Stock that is equal to the product of
(a) the total number of shares proposed to be transferred and (b) a fraction,
the numerator of which is the total number of shares owned by such Minority
Stockholder and the denominator of which is the total number of shares owned
by HCI and all stockholders proposing to participate in such sale.
 
  Sale Restrictions on HCI and New PanAmSat. The Stockholder Agreement will
provide that HCI and its affiliates (other than New PanAmSat) will be
restricted from disposing of their shares of New PAS Common Stock from the
Closing through the earlier of (i) the date of the disposition of shares by
the Minority Stockholders which causes the Minority Stockholders to
beneficially own, in the aggregate, less than 5% of the number of shares of
New PAS Common Stock outstanding immediately after the Closing, or (ii) the
date that is twelve months (plus certain additional periods of time) after the
date (the "Commencement Date") that is the earlier of (x) the first
anniversary of the Closing (or eighteen months after the Closing in the event
the Minority Stockholders sell more than five million shares of PAS Common
Stock (except as provided in the Stockholders Agreement) between September 20,
1996 and the Closing) and (y) the date New PanAmSat notifies the Minority
Stockholders that it has completed the refinancing of up to $1.725 billion of
indebtedness incurred by New PanAmSat in connection with the Reorganization.
New PanAmSat will be subject to similar restrictions on issuances of new
shares of New PAS Common Stock, except that such restrictions will not apply
to sales of New PAS Common Stock by New PanAmSat prior to the Commencement
Date to the extent that the net proceeds of such sales are used entirely to
refinance the $1.725 billion in new indebtedness that will be incurred by New
PanAmSat on the Closing. None of the foregoing sale restrictions will apply to
reasonable issuances of shares by New PanAmSat for employee plans, in
acquisitions from non-affiliates, pursuant to a dividend reinvestment plan or
upon exercise or conversion of previously issued options, warrants or
convertible securities.
 
  Sale Restrictions on the Minority Stockholders. The Stockholder Agreement
will provide that each of the Minority Stockholders be restricted from
disposing of its shares of New PAS Common Stock after the Closing Date and
prior to the Commencement Date except to certain permitted transferees.
Notwithstanding the foregoing, Minority Stockholders may sell New PAS Common
Stock in private transactions with the consent of HCI, which consent will be
granted if, in HCI's reasonable judgment, such transfer will not materially
adversely affect New PanAmSat's financing plans or the price of or demand for
New PAS Common Stock.
 
  The Minority Stockholders, HCI and New PanAmSat are considering modifying
the above described sale restrictions applicable to New PanAmSat and the
Minority Stockholders. In general, such modifications would permit the
Minority Stockholders to sell shares of New PanAmSat Common Stock during the
period from the Closing until the Commencement Date, and permit New PanAmSat
to sell shares of New PanAmSat Common Stock for the twelve to eighteen month
period after the Commencement Date.
 
 
                                      91
<PAGE>
 
  Standstill Right. The Stockholder Agreement will require that, for five
years after the Closing Date, HCI and its affiliates will be prohibited from
acquiring more than 81% of the outstanding common equity interests in New
PanAmSat, except (i) pursuant to a merger approved by a majority of the shares
of New PAS Common Stock not owned by HCI and its affiliates, (ii) pursuant to
a tender offer recommended by a majority of the Disinterested Directors of New
PanAmSat and a second-step merger which offers the same per share
consideration to all holders of New PAS Common Stock and in which more than
half of the outstanding New PAS Common Stock not owned by HCI and its
affiliates at the inception of the transaction is either tendered or voted in
favor of the transaction and (iii) pursuant to another transaction that
provides for parity of treatment of holders of New PAS Common Stock and is
approved by the holders of a majority of the shares of New PAS Common Stock
not owned by HCI and its affiliates and by a majority of the Disinterested
Directors of New PanAmSat.
 
  Board of Directors. The Stockholder Agreement also will provide that each of
HCI and the Minority Stockholders will be obligated to cause the New PanAmSat
Board to consist of ten members, eight of which will be designated by HCI (one
of whom shall be Frederick A. Landman so long as he is the Chief Executive
Officer of New PanAmSat). The former holders of PAS Class A Common Stock and
their transferees, as a group, will be entitled to appoint one director so
long as such holders and their permitted transferees, collectively, own more
than 4% of the shares of New PAS Common Stock outstanding immediately after
the Closing Date. Similarly, S Company will be entitled to appoint one
director so long as S Company and its permitted transferees collectively own
more than 4% of the shares of New PAS Common Stock outstanding immediately
after the Closing Date.
 
  Transactions with Affiliates. The Stockholder Agreement will provide that,
for five years after the Closing Date, HCI and its affiliates (other than New
PanAmSat) will be prohibited from proposing, approving or amending any
contract, agreement or understanding with New PanAmSat, except on terms that
are no less favorable to New PanAmSat than those ordinarily entered into in
comparable transactions by HCI or the relevant HCI affiliate on an arms'
length basis with an unrelated party. All material transactions between HCI or
an HCI affiliate and New PanAmSat will be subject to approval by a committee
comprised of Disinterested Directors of New PanAmSat.
 
  HE's Covenant Not to Compete. The Stockholder Agreement also will provide
that, for five years after the Closing Date, HE and any entity owned 50% or
more by HE (excluding New PanAmSat and its subsidiaries) (the "Committing
Companies") will be restricted from competing with New PanAmSat in the Galaxy
Business in any geographic area. The covenant not to compete described in the
preceding sentence will not apply to the Committing Companies with respect to
(a) all aspects of the DTH satellite business, (b) all aspects of value-added
services, including the provision of transponder capacity that is ancillary to
the services rendered by such company, (c) all aspects of the business of
providing satellite capacity to the U.S. government or any department or
agency thereof; (d) the provision of project financing, or taking of a
minority equity position in any other satellite operating or service company
as part of a satellite sale, (e) all aspects of the business of manufacturing
and selling or leasing satellites in their entirety, other than the sale or
lease of individual transponders or portions thereof (unless otherwise
permitted by these exceptions) and (f) the acquisition of a third party where
the competing business is not a substantial part of such acquired business,
provided that such competing business shall be disposed of in a commercially
reasonable manner as soon as commercially reasonable after such acquisition.
In addition, HE will retain and continue to operate all aspects of the
business of providing mobile satellite services and all aspects of SPACEWAY.
 
  New PanAmSat's Covenant Not to Compete. The Stockholder Agreement also will
require that, for five years after the Closing Date, New PanAmSat and its
controlled affiliates will not engage in any aspect of the direct broadcast
satellite business or the sale or lease of transponders, other than through
the provision of transponder services and the provision of other value-added
services ancillary thereto to third parties engaged in the direct broadcast
satellite business, provided that New PanAmSat will not be precluded from
providing project financing to such third parties, or taking minority equity
positions in such third parties, in connection with sale or lease of
transponders or channels therein or the provision of transponder services. In
addition, for so long as
 
                                      92
<PAGE>
 
Televisa and its controlled affiliates own any New PAS Common Stock, neither
New PanAmSat nor any of its controlled affiliates may own any equity interest
in a DTH enterprise offering predominantly Spanish language programming in the
Americas or the Iberian Peninsula.
 
  First Offer Rights. The Stockholder Agreement will provide that if New
PanAmSat determines to launch a satellite that uses certain Ku-band BSS
frequencies into certain specified orbital slots within five years after the
Closing Date, HE will have a right of first offer to commence negotiations for
up to a three month period to attempt to enter into a full life service
agreement with respect to some or all, but not less than half, of the
available capacity on the BSS band transponders on the first such satellite
that New PanAmSat determines to place into each slot on terms and conditions
to be negotiated in good faith and consistent with normal business practice.
Generally, if negotiations are not commenced or do not result in a signed
agreement within the specified periods, neither party shall have any
obligation to the other with respect to such satellite.
 
REGISTRATION RIGHTS AGREEMENT
 
  On the Closing Date, the Registration Rights Holders and New PanAmSat will
enter into the Registration Rights Agreement with respect to the shares of New
PAS Common Stock to be received by the Registration Rights Holders in the
Merger, the Univisa Contribution and the Asset Contribution. The Registration
Rights Agreement will give the Registration Rights Holders the right to demand
that New PanAmSat register all or any portion of New PAS Common Stock held by
them, provided that the aggregate value of shares of New PAS Common Stock
requested to be registered pursuant to any demand (including shares held by
Registration Rights Holders not making such demand but requesting to be
included in such registration) shall be at least $100 million. The
Registration Rights Holders that receive shares of New PAS Common Stock in
respect of shares of PAS Class A Common Stock and Converted Shares and certain
of their transferees, as a group, and S Company and certain of its
transferees, as a group, will each be entitled to three such demand
registrations and HCI will be entitled to six demand registrations. Such
demand registrations will be subject to certain restrictions including
postponement by New PanAmSat for a limited period if such registration would
interfere with any proposed offering of shares, pending financing,
acquisition, corporate reorganization or other significant transaction
involving New PanAmSat.
 
  The Registration Rights Agreement will provide that demand registrations
will also be subject to customary underwriter "cutbacks," in which event the
amount of shares to be offered for the account of each Registration Rights
Holder shall be reduced pro rata on the basis of the number of shares to be
registered by each Registration Rights Holder.
 
  If New PanAmSat seeks to register, in a proposed firm commitment
underwritten offering solely for cash for its own account (other than a
registration statement (a) on Form S-8 or any successor forms thereto, or
(b) filed solely in connection with a dividend reinvestment plan or employee
benefit plan of New PanAmSat or its affiliates) or for the account of any
holder of New PAS Common Stock, each of the Registration Rights Holders also
will have the right to request that New PanAmSat include any or all of their
shares in the proposed offering. The Registration Rights Agreement will limit
the ability of each Registration Rights Holder to effect a public sale or
distribution of its shares of New PAS Common Stock during certain periods if
New PanAmSat or an underwriter (in the case of an underwritten public offering
by New PanAmSat), as the case may be, determines that a public sale or
distribution of such shares would have a material adverse impact on an
offering of New PAS Common Stock for which New PanAmSat has filed a
registration statement.
 
  In any registration effected pursuant to the Registration Rights Agreement,
each Registration Rights Holder will be required to pay all underwriting
discounts, commissions or fees and transfer taxes related to the offering and
sale of its shares of New PAS Common Stock as well as all other fees and
expenses, including its counsel, in connection with such registration. New
PanAmSat will be obligated to pay all registration and filing fees, printing
expenses, fees and disbursements of counsel, independent certified public
accountants, and other persons retained by New PanAmSat and other expenses
incurred by New PanAmSat in connection with any such registration.
 
                                      93
<PAGE>
 
  The Registration Rights Agreement also will contain certain customary
indemnification provisions whereby New PanAmSat will indemnify the
Registration Rights Holders, the prospective underwriters and other securities
industry personnel participating in the distribution of shares of New PAS
Common Stock for liabilities arising out of actual or alleged material
misstatements or omissions in a registration statement that were not furnished
by the Registration Rights Holders or underwriters. Likewise, each
Registration Rights Holder will indemnify New PanAmSat for liabilities arising
out of actual or alleged material misstatements or omissions made in the
registration statement in reliance on information provided in writing to New
PanAmSat by such Registration Rights Holder.
 
INCOME TAX INDEMNIFICATION AND ALLOCATION AGREEMENT
 
  Pursuant to the Reorganization Agreement, on the Closing Date, HE and New
PanAmSat will enter into the Tax Agreement. The Tax Agreement principally will
provide that, following consummation of the transactions contemplated by the
Reorganization Agreement, HE will be responsible for and indemnify New
PanAmSat and its direct and indirect subsidiaries against (i) any federal,
state or local income taxes of any of the entities comprising the Galaxy
Business prior to the Asset Contribution for all taxable years or other
periods ending on or before the Closing Date and (ii) any liability for
transfer taxes applicable to the asset transfers made in connection with the
Reorganization. The Tax Agreement also will establish, as between HE and New
PanAmSat, certain procedures for the filing of state income tax returns and
the allocation and payment of state income tax liabilities, in each case, for
periods subsequent to the Closing Date.

                             BUSINESS OF PANAMSAT
 
OVERVIEW
 
  PanAmSat operates the world's first privately owned global (excluding
domestic U.S.) satellite communications system. PanAmSat currently provides
satellite services primarily to the broadcasting and business communications
markets and also provides services to the long-distance telephony market. In
connection with its current services, PanAmSat is pursuing international
opportunities in the satellite DTH television market. See "--DTH Strategy."
 
  PanAmSat's first satellite, PAS-1, was launched in June 1988 for service
over the Atlantic Ocean Region and is a leading satellite for television and
cable programming distribution in Latin America. PanAmSat's second satellite,
PAS-2, was launched in July 1994 for service over the Pacific Ocean Region and
is a leading satellite for programming distribution in the Asia-Pacific
Region. PanAmSat's PAS-4 satellite was launched in August 1995 for service
over the Indian Ocean Region and is a leading satellite for programming
distribution in south Asia and Africa. PanAmSat's PAS-3 satellite was launched
in January 1996 for service over the Atlantic Ocean Region. PAS-3 and PAS-1
are the leading satellites for television and cable programming distribution
in Latin America. PanAmSat expects to launch two additional satellites to
serve the Atlantic Ocean Region: PAS-6 in May 1997; and PAS-5 in July 1997.
However, SS/Loral has recently informed PanAmSat of circumstances that could
result in a delay in the launch of PAS-6. See "RISK FACTORS--Risk of Delays;
Excess Weight." PanAmSat intends to launch PAS-7 during the first quarter of
1998 and PAS-8 during the second quarter of 1998. PAS-7 and PAS-8 are expected
to serve the Indian Ocean Region and the Pacific Ocean Region, respectively.
PanAmSat expects that in the future it will launch additional satellites to
meet then-anticipated customer demand. There can be no assurance, however,
that the schedule for PanAmSat's future satellite launches will be met.
 
CUSTOMERS AND MARKETS
 
  PanAmSat is the first private company to provide global (excluding domestic
U.S.) satellite services. PanAmSat has several hundred customers and, at
December 31, 1996, had signed long-term contracts to provide satellite
capacity on PAS-1, PAS-2, PAS-3, PAS-4, PAS-5 and PAS-6 aggregating
approximately $3.7 billion. At December 31, 1996, PanAmSat's long-term
contracts were comprised of approximately $293.7 million expected to be
received in the year ending December 31, 1997, $342.0 million expected to be
received in the year ending December 31, 1998, $342.4 million expected to be
received in the year ending December 31, 1999, $338.1 million expected to be
received in the year ending December 31, 2000 and $2,332.4 million expected to
be received on and after January 1, 2001. PanAmSat's customers for television
programming distribution and other broadcasting services include ABS-CBN
Broadcasting Co., Arab Radio and Television, the BBC, Bloomberg Information
Television, CBS, China Central Television, Chinese Television Network, Country
Music Television, Discovery, Disney, ESPN, 20th Century Fox, Fuji TV, HBO, Fox
Sports International, Liberty Sports, M-Net/MultiChoice, NBC, NHK,
SABC/Sentech, Sony, Taiwan Asia Space Cable, Tele-Communications, Inc.,
Televisa, Television Broadcasts International, Television Corporation of
Singapore, Turner Broadcasting Systems (CNN, Cartoon Network, TNT) and Viacom
(MTV, Nickelodeon), and for business communications services include the
Associated Press, Citicorp, Credit Suisse, Dow Jones/Telerate, El Tiempo, Ji
Tong, Impsat, MCI, Procedatos, PT. Primacom, Reuters, Sara Lee, Sprint,
Transtel and the U.S. government. PanAmSat's customers for DTH Services
include Sky Entertainment Services Latin America, one of the Latin America
JVs, Showtime (also known as Gulf DTH) and Firstnet, which operate in the
Middle East; and M-Net/MultiChoice and SABC/Sentech, which operate in South
Africa; and TVBI and Taiwan Asia Satellite Cable Inc., which operate in
Taiwan.
 
  PanAmSat's video distribution services, which generated approximately 83% of
PanAmSat's total revenues for the year ended December 31, 1996, include the
provision of satellite capacity and services for (i) television programming
distribution, (ii) "backhaul" operations (i.e., the transmission of video
feeds from one location to another) and (iii) ad hoc services, such as the
transmission of special events and live news reports. PanAmSat's business
communications services, which generated approximately 16% of PanAmSat's total
revenues for the year ended December 31, 1996, include (a) the provision of
satellite capacity to communications carriers that provide private business
networks for data, voice, corporate video and Internet communications and (b)
the
 
                                      95
<PAGE>
 
provision of such networks and related services by PanAmSat directly to end-
users. PanAmSat's telephony services provide satellite capacity for use in
domestic (non-U.S.) and international public telephone networks.
 
  PanAmSat plans to provide DTH satellite services to specific television
markets around the world. In November 1995, PanAmSat announced that it would
serve as a satellite service provider for the Latin America DTH service to be
offered by Globo, Televisa, News Corp. and TCI. On February 29, 1996, PanAmSat
entered into the 1996 Letter Agreement with Globo, Televisa and News Corp. to
provide service to the Latin America JVs to be formed by Globo, Televisa, News
Corp. and TCI on 48 transponders ultimately on PAS-5 and PAS-6, with temporary
service on PAS-3 pending the commencement of service on PAS-6. This capacity
would enable the Latin America JVs to broadcast to Latin America, the
Caribbean and certain areas of the southern United States approximately 500
digital channels to subscribers using small 24-36 inch (60-90 cm) antennas and
to permit distribution of program packages of approximately 120 digital
channels to specific market areas. The 1996 Letter Agreement contemplates that
three separate full-scale transponder agreements will be entered into for the
regions of (i) Brazil, (ii) Mexico, including other Spanish- and Portuguese-
speaking parts of North America, and (iii) Latin America (except Brazil and
Mexico). A full-scale transponder agreement has been entered into (and
subsequently amended) with respect to 12 transponders for Brazil (the "Brazil
Transponder Agreement") and the 1996 Letter Agreement remains in force as to
the remaining 36 transponders for the other regions. Execution of full-scale
transponder agreements for the other two regions is subject to negotiation and
no assurance can be given that such full-scale agreements will be consummated.
See "--DTH Strategy" and "THE DTH SALE."
 
  The 1996 Letter Agreement and the Brazil Transponder Agreement provide for
minimum payments over their respective terms of approximately $1.3 billion,
depending upon the actual useful life of the satellites in question, their
predicted performance and their in-service dates. For most of the
transponders, the amounts to be paid reflect service fees that are equal to
PanAmSat's best estimate of the cost to design, construct, launch, insure and
operate the satellites, and for the balance of the transponders, the amounts
to be paid reflect service fees that are based on a fixed price. On the cost-
based transponders, PanAmSat also could receive revenue sharing from the Latin
America JVs. The Brazil Transponder Agreement was entered into on the same
economic terms as to the applicable 12 transponders as were set forth in the
1996 Letter Agreement. Subsequent amendments to the Brazil Transponder
Agreement and the 1996 Letter Agreement address the possibility of a longer
than originally anticipated life of PAS-6 (under which the agreements may be,
but are not required to be, extended beyond the originally anticipated useful
life of PAS-6) but do not alter the minimum values anticipated under the 1996
Letter Agreement, as originally entered into.
 
  Under an agreement dated as of September 20, 1996 (the "Spain Transponder
Agreement"), PanAmSat will provide to Televisa Spain transponder service from
five PAS-3 Ku-band transponders, at least three of which will be for the
delivery of television services to Spain, that may include DTH services. The
transponder service fees reflect market rates. This agreement is unaffected by
the DTH Sale.
 
  PanAmSat has also designed PAS-2, PAS-4 and PAS-7 and is designing PAS-8
with the capability of providing high-powered digital DTH service in their
respective coverage areas. PanAmSat's satellites are platforms for operational
DTH services in Brazil, the Middle East and South Africa, and for planned DTH
services for India and Spanish-speaking Latin America. Digital DTH channels on
PanAmSat's satellites are capable of providing image and sound quality
superior to current cable, MMDS or broadcast television services.
 
  PanAmSat believes that the demand for international satellite services in
the broadcasting and business communications markets will grow substantially
in the foreseeable future. This growth is expected to result from (i)
increased distribution of television programming to national, regional and
international audiences, (ii) continuing worldwide deregulation of
telecommunications markets, (iii) continuing technological advancements and
(iv) economic development worldwide and the increasing globalization of
business.
 
CONVERSION AND INITIAL PUBLIC OFFERING
 
  Between 1992 and March 2, 1995, PanAmSat operated as the Partnership and
prior to 1992, as a sole proprietorship and through other forms of
organization. On March 2, 1995, pursuant to an amended Exchange
 
                                      96
<PAGE>
 
and Subscription Agreement and Plan of Reorganization, PanAmSat, the
Partnership (PanAmSat's predecessor) and its partners consummated the
Conversion. In connection therewith, (i) Rene Anselmo, PanAmSat's late
Chairman of the Board and Chief Executive Officer, members of the family of
the late Mr. Anselmo, trusts for the benefit of certain Anselmo family
members, Frederick A. Landman, PanAmSat's current President and Chief
Executive Officer, and Lourdes Saralegui, Executive Vice President of PanAmSat
(collectively, the "Anselmo Group"), exchanged their interests in the
Partnership for shares of PAS Class A Common Stock, representing approximately
49.66% of the outstanding common stock of PanAmSat, (ii) USHI exchanged its
interest in the Partnership for shares of PAS Class B Common Stock,
representing approximately 50.15% of the outstanding common stock of PanAmSat
and (iii) a partner of the Partnership exchanged his interest in the
Partnership for shares of PAS Ordinary Common Stock, representing
approximately .19% of the outstanding capital stock of PanAmSat. On September
27, 1995, PanAmSat completed its IPO of 18,920,000 shares of PAS Ordinary
Common Stock, including 4,595,676 shares held by members of the Anselmo Group
and Televisa, and PanAmSat received net proceeds of approximately $229
million. In addition, PanAmSat has issued 9 3/4% Senior Secured Notes due 2000
(the "Senior Secured Notes"), 11 3/8% Senior Subordinated Discount Notes due
2003 (the "Discount Notes," and together with the Senior Secured Notes, the
"1993 Notes") and the PAS Preferred Stock. Copies of the indentures and
certificate of designation relating thereto have been filed or incorporated by
reference as exhibits to the Registration Statement of which this Proxy
Statement/Prospectus is a part. Summaries of the Senior Secured Notes,
Discount Notes and PAS Preferred Stock are also available in PanAmSat's
registration statement on Form S-1, filed on April 2, 1996 under file number
333-3114.
 
BUSINESS STRATEGY
 
  PanAmSat's strategy has evolved from its experience with the development and
marketing of PAS-1, PAS-2, PAS-3 and PAS-4 and its analysis of the current and
anticipated worldwide market for satellite communications services. PanAmSat
believes that implementation of its strategy has established PanAmSat as an
international leader for broadcasting and business communication services.
PanAmSat's strategy is to continue to focus on six key elements:
 
  . Customer-driven service offerings;
 
  . Superior satellite system technical characteristics;
 
  . Emphasis on broadcasting services;
 
  . Concentration on other high-growth communications services;
 
  . Early market entry; and
 
  . Global coverage.
 
 Customer-Driven Service Offerings
 
  PanAmSat believes that the most important aspect of its business strategy is
that PanAmSat is market driven and responsive to its customers' needs.
PanAmSat offers customers ease-of-access and operation with respect to the use
of satellite capacity. PanAmSat also offers customers a complete end-to-end
package of satellite communications services on a one-stop shopping basis. The
end-to-end services provided by PanAmSat include satellite capacity, teleport
services and network services, including the design, integration, management
and maintenance of networks and the procurement of ground equipment. PanAmSat
furnishes substantially all of its terrestrial services outside of the United
States through independent contractors.
 
  PanAmSat developed its service strategy when it first commenced operations,
at which time Intelsat was PanAmSat's only significant competitor. Intelsat
generally provides services only through its signatories and not directly to
end-users. Intelsat's rates are often inflexible, fixed by tariff and
customarily include a markup by
 
                                      97
<PAGE>
 
each signatory. In addition, Intelsat and its signatories have historically
focused on international telephony services, rather than the requirements of
other users, such as television broadcasters and business communications
network users. Intelsat also typically has launched satellites with generic
beam designs that have generally been suitable primarily for transmission to
the large, expensive "gateway" earth stations of national telephone companies.
See "--Competition."
 
 Superior Satellite System Technical Characteristics
 
  The satellites in PanAmSat's global (excluding domestic U.S.) satellite
system (the "PAS Global System") are designed to provide high-transmission
power, a key technical characteristic sought by broadcasting and business
communications customers. The satellites' high power and other technical
characteristics permit high-quality transmissions for the distribution of
television programming and enable broadcasting and business communications
customers to utilize cost-effective networks using small, low-cost antennas on
the ground.
 
  The orbital slots for PanAmSat's satellites were selected to optimize the
satellites' coverage and the global connectivity of the PAS Global System.
Since orbital slots are limited in number and each slot provides a different
range of coverage areas, PanAmSat believes that its early selection of orbital
slots enhanced its technological capabilities and scope of coverage. The
geographic coverage patterns of the satellites in the PAS Global System are
custom-designed to focus signal power over centers of population and economic
activity.
 
 Emphasis on Broadcasting Services
 
  PanAmSat expects the international broadcasting market to experience
significant growth as broadcasters and cable television programmers seek to
expand the distribution of their programming to national, regional and
international audiences worldwide. Future demand is expected to include
international television programming distribution, backhaul operations and ad
hoc services. PanAmSat has designed its satellite services to meet the program
distribution requirements of broadcasters and programmers. The technical
characteristics and coverage areas of each of PAS-2, PAS-3, PAS-4, PAS-5, PAS-
6 and PAS-7 were specified after extensive discussions with PanAmSat's major
customers and potential customers regarding their service needs. The technical
specifications of PAS-8 are in the design stages and subject to change.
PanAmSat facilitates television programming distribution by offering satellite
capacity, teleport services and technical services.
 
  In addition, PanAmSat provides satellite capacity on PAS-3, and plans to
provide satellite capacity on PAS-5 and PAS-6, for digital DTH services in
response to the desire of broadcasters and programmers to increase their
viewing audiences in Latin America. PanAmSat expects there to be significant
demand for digital DTH services in Latin America because of the large number
of television households without cable services or access to extensive
programming in the region. See "--DTH Strategy."
 
 Concentration on Other High-Growth Communications Services
 
  PanAmSat targets other high-growth markets where its satellites provide
advantages to users of private business networks and long-distance telephony
services in rural and underdeveloped areas. Business and other organizations,
particularly those with sites in remote locations or inadequate terrestrial-
based services available to them, have become increasingly dependent upon
satellites to serve their communications requirements. These communications
requirements are based on the need to collect, process, respond to and
disseminate information, such as ATM and credit card verification and
inventory control. Organizations such as banks and retail chains are, in
increasing numbers, installing very small on-site antennas to set up
satellite-based communications networks instead of using higher cost and/or
unreliable terrestrial telephone lines. In addition, a growing number of
domestic and regional telephone companies, especially in developing countries,
are using the satellite capacity of PanAmSat and others to offer long-distance
telephony services in rural areas. Internet service providers in several
countries in Latin America and Asia also use satellites for international
access to the Internet.

 Early Market Entry
 
  PanAmSat's strategy is to launch high-powered satellites early in their
respective markets that are capable of delivering broadcast and business
communications services via signals that may be received by users of small
antennas. Partly as a result of its early market entry, PanAmSat believes it
has established PAS-1, PAS-2, PAS-3 and PAS-4 as leading satellites for
television programming distribution in their respective coverage areas and as
important satellites for private business networks.
 
 Global Coverage
 
  PanAmSat is the first private company to provide global (excluding domestic
U.S.) satellite services. Accordingly, customers are able to contract solely
with PanAmSat for all of their global satellite communications requirements.
Previously, users of satellites who wanted to communicate or transmit over
broad areas were required to enter into contracts with a number of different
Intelsat signatories and/or regional and domestic operators that often
provided overlapping coverage or had substantial gaps in their coverage.
Customers with global communications requirements include video programmers,
broadcasters, news and sports organizations and operators of public and/or
private communications networks.
 
  PanAmSat believes that its orbital slots provide a competitive advantage for
PanAmSat's global satellite services due to the limited number of available
slots that provide commercially desirable transoceanic coverage. Applications
for orbital slots for C-band and Ku-band geostationary satellites have been
filed by the U.S. government with the ITU on behalf of PanAmSat at 45(degrees)
W.L. (Atlantic Ocean Region), 43(degrees) W.L. (Atlantic Ocean Region),
68.5(degrees) E.L. (Indian Ocean Region), 72(degrees) E.L. (Indian Ocean
Region), 191(degrees) W.L. (Pacific Ocean Region) and 194(degrees) W.L.
(Pacific Ocean Region). PanAmSat has requested registration of a second
satellite at 43(degrees) W.L. (Atlantic Ocean Region) and a satellite at
58(degrees) W.L. (Atlantic Ocean Region). See "--Government Regulation--
International Telecommunications Union Coordination." In addition, PanAmSat
has applied for U.S. government authorization to use 79(degrees) W.L.
(PanAmSat has informally asked that the FCC associate this application with
the 81(degrees) W.L. orbital location) and 93(degrees) W.L. for C-band and Ku-
band geostationary satellites. If these two applications are granted, the FCC
would have to assign different orbital locations because it since has assigned
the 79(degrees) and 93(degrees) W.L. locations to other applicants. PanAmSat
also has applied for nine orbital slots for Ka-band geostationary satellites,
one of which the FCC tentatively has assigned to it subject to final action on
its applications for those orbital locations. Pursuant to an agreement among
all the Ka-band applicants that is subject to FCC approval, PanAmSat expects
to be assigned a second Ka-band orbital location. The U.S. government has
filed with the ITU for these additional slots, substantially all of which are
sought by other U.S. applicants as well. See "--Government Regulation--U.S.
Regulation."
 
SERVICES
 
  In the year ended December 31, 1996, PanAmSat's revenues were derived from
the following markets:

</TABLE>
 
 Video Distribution
 
  Local, domestic and international broadcasters use satellite capacity and
services for (i) television programming distribution, (ii) "backhaul"
operations (i.e., the transmission of video feeds from one location to
another) and (iii) ad hoc services such as the transmission of special events
and live news reports from the scene of the event. Currently, the largest
market for broadcasting services is the full-time leasing of satellite
capacity
 
                                      99
<PAGE>
 
by programmers for distributing programming to television stations, local
cable operators, master antenna systems and, on a limited basis, directly to
homes.
 
  Television Programming Distribution. PanAmSat's program distribution
strategy is to establish each of its satellites as a leading satellite for the
distribution of television programming to cable and other redistribution
systems in its service region and to position the PAS Global System as a
single source for the global (excluding domestic U.S.) distribution of
television programming.
 
  In January 1989, CNN became the first international programmer to use PAS-1
to distribute television programming in Latin America. Over the next twenty-
four months, PanAmSat entered into agreements with other full-time
programmers, such as ESPN, HBO, Televisa and TNT. Local cable television
operators and over-the-air broadcasters installed antennas to receive
programming from this core group of international programmers, thus creating
an infrastructure in Latin America to receive PAS-1 signals. As a result of
the installed base of antennas pointed at PAS-1, programmers desiring regional
distribution sought to use PAS-1 to reach that audience and compete
effectively with the major full-time video programmers in Latin America. Upon
the commencement of PAS-3 services on February 19, 1996, PanAmSat started
migrating some broadcast customers from PAS-1 to PAS-3, under a plan to
provide additional PAS-1 capacity for business communications services. PAS-1
and PAS-3 are now the leading satellites for television and cable programming
distribution in Latin America. As of December 1996, PAS-1 and PAS-3
cumulatively distributed more than 60 television and cable programming
channels to Latin America.
 
  For domestic Latin America broadcasters, PanAmSat offers the ability to
create national networks where, due to local geography and high costs, none
was possible before. For example, Telefe, the leading television network in
Argentina, was created when a group of independent local Argentine television
stations began using PAS-1 in December 1990 for national programming
distribution. Domestic broadcasters in Peru and Chile also used PAS-1 to
create national networks.
 
  PanAmSat offers broadcasters direct access to PanAmSat satellites from their
own facilities. This direct access leads to both economic and operational
efficiencies for the broadcasters. PanAmSat satellites also offer a number of
other advantages for domestic broadcasters. Domestic broadcasters may, for
example, purchase certain segments of an international programmer's feed
(e.g., a sports event from ESPN or a news show from CNN) for broadcast as part
of their own programming, without incurring the cost of adding a separate
earth station to receive the international programmer's segments. In addition,
domestic broadcasters can sell their programming (e.g., a local sports event)
regionally or internationally because PanAmSat satellites allow them to use
the same transmission antenna to relay their programming internationally as
well as domestically.
 
  Local cable and television station operators also benefit from the use of
PanAmSat satellites for television programming distribution. For example, in
Latin America, such operators need only two small earth stations pointed at
each of PAS-1 and PAS-3 to receive dozens of channels from both domestic and
regional broadcasters.
 
  In the Pacific Ocean Region, PanAmSat's strategy has been to establish PAS-2
as the leading satellite for the trans-Pacific distribution of television and
cable programming. As of December 1996, PAS-2 provided pan-Asian C-band
coverage and access to the western United States for more than 20 broadcast
customers, including ABS-CBN (Philippines), Asia Business News, the BBC,
Bloomberg Information Television, China Central Television, Chinese Television
Network (Hong Kong), Discovery, Disney, ESPN and Liberty Sports, NBC, NHK
(Japan), Television Broadcasts International (Hong Kong) and Television
Corporation of Singapore.
 
  In the Indian Ocean Region, PanAmSat's strategy has been to establish PAS-4
as the leading satellite for the distribution of television and cable
programming throughout southern Asia, including the Indian Subcontinent and
the Middle East. Broadcast customers for PAS-4 C-band services throughout
southern Asia include Asia Business News, the BBC, China Central Television,
Discovery, Disney, Doordarshan (India), ESPN, HBO, Jain TV, Sony and Turner
Broadcasting Systems. In addition, PAS-4 is designed to provide C-band program
distribution services throughout Africa and northern Asia.
 
                                      100
<PAGE>
 
  For the global distribution of television programming, customers that have
agreements with PanAmSat for service over several satellites include the BBC,
China Central Television, ESPN, Doordarshan (India), Liberty Sports, NHK,
Turner International and Viacom International.
 
  Compressed Digital Video. At December 31, 1992, PanAmSat had sold out its
capacity on PAS-1 for full-time television programming distribution to Latin
America. Since February 1993, PanAmSat has used compressed digital video
("CDV") technology to expand its satellite channel capacity and offer digital
television channels to its broadcast customers at a lower cost than comparable
analog capacity. As part of its marketing strategy, PanAmSat designates
certain capacity on each satellite for digital channels that have generated,
and PanAmSat expects will continue to generate, substantially more revenue per
transponder as a result of video compression even though each customer's cost
per channel distributed by satellite is reduced. PanAmSat also believes that
CDV technology provides television viewers with higher quality channels, movie
programming options, new data and other service applications. PanAmSat is
using a range of leading CDV suppliers for broadcast services on PAS-2, PAS-3
and PAS-4 from various teleport facilities throughout the world. In April
1996, PanAmSat announced that it would provide global CDV services using
equipment by Scientific-Atlanta that meets the MPEG-2/DVB international
digital transmission standards.
 
  Backhaul Operations. Broadcasters use satellite capacity for backhaul
operations, such as transporting programming from a broadcaster's foreign news
bureau to its broadcast center for simultaneous or later transmission.
PanAmSat's services in this area are focused on the transportation of program
material and syndicated programming for broadcasters on a scheduled basis.
Program distributors utilize 24-hour full-time channels or scheduled part-time
video services on PanAmSat satellites to transport programming between
locations. NHK, a leading Japanese broadcaster, for example, utilizes full-
time transponders on PAS-1, PAS-2 and PAS-4 for the transportation of
programming and news.
 
  Special Events and Live News Coverage. Broadcasters use PanAmSat to transmit
coverage of live scheduled special events to programmers on a short-term ad
hoc basis. For instance, PanAmSat transmitted approximately 10,000 hours of
television coverage of the 1996 Summer Olympics over the PAS Global System.
PanAmSat also provides broadcast services to relay live news coverage, short
duration video feeds and syndicated programming for broadcasters on a
scheduled or ad hoc basis. For instance, PanAmSat broadcasted more than 150
hours of international news coverage of the 1996 U.S. Presidential election
for U.S., European and Asian broadcasters.
 
  Radio. Radio broadcasters use satellites for program distribution, coverage
of news and sporting events and other broadcast and backhaul applications.
Customers for radio services on PAS-1 include BBC World Service, Radio France
International, Caribbean News Agency and Radio Netherlands.
 
  DTH Distribution. High powered DTH satellites are designed to enable
broadcasters and programmers to reach the maximum number of television viewers
possible. Programming distributed over a DTH satellite is accessed by
households and also by local cable systems that redistribute that programming
through ground-based cable to households. In addition, the total television
audience can be increased significantly because the satellite's high
transmission power enables households equipped with 24-36 inch (60-90 cm)
satellite dishes and related equipment to receive the programming directly
from the satellite.
 
  PanAmSat's strategy includes launching and operating satellites capable of
providing DTH services. Each of PAS-2 through PAS-8 has or will have the
capability to provide high-powered DTH service in its respective coverage
area. For instance, M-Net/MultiChoice and SABC/Sentech commenced transmissions
in September 1995 of a multichannel DTH service throughout South Africa using
transponders on PAS-4. PanAmSat's satellites are also platforms for
operational DTH services in Brazil and the Middle East and planned DTH
services in India and Spanish-speaking Latin America. See "--DTH Strategy."
 
  Other Services. PanAmSat offers a number of additional services to
broadcasters. These include teleport services such as complete network support
and signal turnaround (e.g., retransmission of a signal from a U.S.
 
                                      101
<PAGE>
 
domestic satellite through PanAmSat's teleports to PAS-1 for distribution to
Latin America and to PAS-2 for distribution to Asia). For instance, PanAmSat
provides transmission uplink services from its teleport in Homestead, Florida,
for the Latin America JVs. PanAmSat also provides third-party services and
equipment such as trucks equipped for live news reports and sporting events
and domestic satellite capacity, if required. In addition, PanAmSat offers
one-stop service management such as coordination and traffic management for
international live news reporting.
 
 Business Communications
 
  PanAmSat's business communications services include (i) the provision of
satellite capacity to communications carriers that provide private business
networks for data, voice, corporate video and Internet communications and (ii)
the provision of such networks and related services by PanAmSat directly to
end-users. Network users utilize satellites rather than ground-based
transmission media because satellite systems provide customers:
 
  . cost savings for large, geographically dispersed networks;
 
  . independence from telephone companies;
 
  . predictability of costs over a long period;
 
  . flexibility in changing and adding remote locations to a network;
 
  . integrated network management and control of all remote locations; and
 
  . increased network availability and lower transmission error rates.
 
Many businesses and organizations currently use satellite communications
networks for certain of their communications needs. For example, retail chains
use satellite business communications networks for rapid credit card
authorization and inventory control. Banks use satellite networks to connect
automated teller machines to processing computers. News agencies use satellite
networks to distribute information continuously to numerous locations, and
paging operators use satellite networks to distribute paging information from
a central switch to multiple remote transmitters for retransmission to pagers.
 
  Carrier Services. The largest portion of PanAmSat's revenues in the business
communications market is derived from the provision of satellite capacity to
domestic and regional communications carriers in Latin America. PanAmSat does
not provide substantial value-added services to such carriers. The provision
of satellite capacity to carriers involves relatively low marketing and
operating costs, while promoting the use of PAS-1 and PAS-3 for business
communications in Latin America. Carriers in Latin America that use PanAmSat
satellite capacity include Infosat of Venezuela, Telegan, S.A. of Colombia and
Impsat of Argentina. U.S. carriers include Sprint and MCI. In addition, the
carrier Ji Tong of China and PT. Primacom of Indonesia use capacity on PAS-2
and Transtel of South Africa uses capacity on PAS-4.
 
  Internet service providers also are using several PanAmSat satellites for
international Internet access. As of December 1996, PanAmSat's satellites
provided access to the U.S. Internet network for Internet service providers in
more than 20 countries in Latin America and Asia.
 
  Governments currently represent one of the single largest users of
communications facilities. The U.S. government has stated that it intends to
move governmental traffic, particularly nonclassified military traffic, off of
dedicated satellites and onto commercial satellites. PanAmSat has participated
from time to time in bids for the U.S. Defense Department's procurements of
several commercial satellite transponders. PanAmSat has provided services
directly to the U.S. State and Defense Departments and currently is providing
services to the U.S. government as a subcontractor to government carriers.
U.S. government users accounted for approximately 2% of PanAmSat's total
revenue for the year ended December 31, 1996.
 
                                      102
<PAGE>
 
  Private Networks. PanAmSat offers end-to-end satellite services for two
types of private business communications networks: International Digital
Services ("IDS") networks and very small aperture terminal ("VSAT") networks.
IDS networks consist of rooftop antennas and are used by customers that have
relatively steady flows of information to and/or from all of the points in the
network. Because of their large transmission requirements, IDS networks
require dedicated, permanent communication links to each point. VSAT networks
differ from IDS networks in that VSAT networks consist of very small (e.g.,
1.2 to 1.8 meters) rooftop antennas and are utilized by customers that need to
send short bursts of data over the network for relatively short periods of
time. Through the use of VSAT technology and sophisticated software, these
networks can be served with a relatively small amount of satellite capacity.
 
  In addition to providing satellite capacity, PanAmSat's services to its
business communications customers include the purchase and installation of on-
site antennas and the design, integration, management, operation and
maintenance of business networks. These services are provided by PanAmSat's
teleports in Ellenwood, Georgia, Homestead, Florida and Napa, California, or
through subcontractors. Examples of PanAmSat's business communications
services using PanAmSat's satellites and teleports include an IDS network
linking Citicorp's regional headquarters in Miami, Florida with eight
locations in Latin America, five other IDS networks for banks and another IDS
network linking several of Reuters' Latin American offices to Reuters offices
in the United States.
 
  Networks using VSATs have been growing rapidly to meet the specialized data
requirements of particular industries, such as banking, mining and retailing.
PanAmSat expects the international VSAT market to grow significantly in the
future. Recognizing both the demand for this service as well as the failure of
existing carriers to provide adequate VSAT services, many governments have
recently deregulated this market.
 
 Telephony
 
  Although PanAmSat was initially not permitted by the FCC to offer
international public telephone service between the United States and any other
country, PanAmSat currently provides domestic and international long-distance
telephony services. PanAmSat provides satellite capacity to domestic telephone
companies in Chile, Nicaragua and Honduras. PanAmSat also provides satellite
capacity to Tricom, a Dominican Republic-based carrier which provides
international long-distance telephone service between the United States and
the Dominican Republic. Tricom is currently the only international telephone
carrier under contract with PanAmSat.
 
  Effective January 1, 1997, the FCC no longer restricts the number of public
switched circuits for fully connected telephone traffic that PanAmSat may
carry. See "--Government Regulation." The emergence of competition for long-
distance services and significant deregulation in several countries such as
the United Kingdom, Japan, Korea, New Zealand, the Philippines and Australia
has led PanAmSat to believe that the long-distance telephony market offers
PanAmSat future opportunities globally.
 
DTH STRATEGY
 
  PanAmSat has designed the Ku-band capacity on the PAS Global System (other
than PAS-1) with the capability of providing DTH services. PanAmSat's strategy
is to provide satellite capacity to customers that provide DTH services.
PanAmSat also contemplates facilitating the development of DTH service in
certain regions by providing satellite capacity and coordinating technical
issues with its customers, without direct investment in the DTH service,
although PanAmSat may receive equity interests under certain circumstances in
connection with its provision of transponder capacity. Based on this strategy,
PanAmSat's satellites are platforms for current DTH services in Brazil, the
Middle East and South Africa and for planned DTH services in India and
Spanish-speaking Latin America.
 
  As part of PanAmSat's digital DTH strategy, PanAmSat intends to provide
satellite capacity on PAS-3, PAS-5 and PAS-6 for digital DTH services in Latin
America, the Caribbean and certain areas of the southern United States.
PanAmSat believes there is significant demand for digital DTH service in these
regions in part
 
                                      103
<PAGE>
 
because of the limited percentage of households that receive television
programming (except in the United States) through other transmission systems
such as cable and wireless cable and, in the United States, the limited amount
of Spanish-language programming available.
 
  Pursuant to the Original MOU, PanAmSat and Televisa intended to establish
and operate a Ku-band digital DTH satellite broadcasting business serving
Latin America. The Original MOU was superseded and terminated by the Revised
MOU, except with respect to certain indemnification obligations in favor of
PanAmSat. Pursuant to Section 1.1 of the Revised MOU and certain oral
agreements in principle with Televisa, PanAmSat has DTH Options to acquire
equity interests in the Latin America JVs and companies formed to sell program
services to consumers in the Iberian Peninsula. An affiliate of HCI is an
investor in a venture that provides DTH services in Latin America. HCI has
made it a condition to the Merger, the Univisa Contribution and the Asset
Contribution that PanAmSat dispose of these DTH Options. See "THE
REORGANIZATION AGREEMENT--Conditions to the Reorganization." Accordingly,
PanAmSat, Televisa and S Company have entered into the DTH Option Purchase
Agreement whereby immediately after the Share Repurchase PanAmSat will sell
the DTH Options to either Televisa, S Company and/or their designees, for a
purchase price of $225 million. The closing of the DTH Sale will occur
substantially concurrently with the receipt by S Company of the consideration
to be paid by New PanAmSat to it pursuant to the Univisa Contribution
Agreement. In connection with the DTH Sale, PanAmSat has received the opinion
of Salomon Brothers, PanAmSat's financial advisor with respect to the DTH
Sale, to the effect that as of September 19, 1996 and based upon and subject
to the qualifications described therein, the consideration to be received by
PanAmSat for the sale of the DTH Options represented fair value to PanAmSat
for the DTH Options from a financial point of view. See "THE DTH SALE."
 
 DTH Services in Latin America
 
  In November 1995, PanAmSat announced that it would serve as a satellite
service provider for the Latin America DTH service to be offered by Globo,
Televisa, News Corp. and TCI. On February 29, 1996, PanAmSat signed the 1996
Letter Agreement with Globo, Televisa and News Corp. to provide service to the
Latin America JVs on 48 transponders ultimately on PAS-5 and PAS-6, with
temporary service on PAS-3 pending the commencement of service on PAS-6. This
capacity would enable the Latin America JVs to broadcast to Latin America, the
Caribbean and certain areas of the southern United States approximately 500
digital channels to subscribers using small 24-36 inch (60-90 cm) antennas and
to permit distribution of program packages of approximately 120 digital
channels to specific market areas.
 
  Under the 1996 Letter Agreement, Globo, Televisa and News Corp. have agreed
to proportionally guarantee 100 percent of the fees for transponder services
to the Latin America JVs. These guarantee obligations may be assigned to TCI
and, with PanAmSat's prior written consent, to new equity participants in the
Latin America JVs. PanAmSat will receive minimum service fees equivalent to
PanAmSat's best estimate of the cost per transponder to PanAmSat of designing,
launching, operating and insuring each satellite for transponders used by the
Latin America JVs. PanAmSat also will receive additional revenue based on
subscriber revenues of the Latin America JVs above a certain threshold, except
that the transponders that will be used by the Latin America JV operating in
Brazil will be charged on a fixed fee basis.
 
  The 1996 Letter Agreement contemplates that three separate full-scale
transponder agreements will be entered into for the regions of (i) Brazil,
(ii) Mexico, including other Spanish- and Portuguese-speaking parts of North
America, and (iii) Latin America (except Brazil and Mexico). The Brazil
Transponder Agreement has been entered into with respect to 12 transponders on
PAS-6 for Brazil, while the 1996 Letter Agreement remains in force as to the
remaining 24 transponders on PAS-6 and 12 transponders on PAS-5 for the other
regions. Execution of full-scale transponder agreements for the other two
regions is subject to negotiation and no assurance can be given that such
full-scale transponder agreements will be executed. See "--Customers and
Markets."
 
  The 1996 Letter Agreement and the Brazil Transponder Agreement provide for
minimum payments over their respective terms of approximately $1.3 billion,
depending upon the actual useful life of the satellites in
 
                                      104
<PAGE>
 
question, their predicted performance and their in-service dates. For most of
the transponders, the amounts to be paid reflect service fees that are equal
to PanAmSat's best estimate of the cost to design, construct, launch, insure
and operate the satellites, and for the balance of the transponders, the
amounts to be paid reflect service fees that are based on a fixed price. On
the cost-based transponders, PanAmSat also could receive revenue sharing from
the Latin America JVs.
 
 DTH Services in Spain
 
  Pursuant to the Spain Transponder Agreement, PanAmSat will provide Televisa
Spain with transponder service from five PAS-3 Ku-band transponders, at least
three of which will be for the delivery of television services to Spain, which
may include DTH services. The transponder service fees reflect market rates.
The Spain Transponder Agreement is unaffected by the DTH Sale.
 
PANAMSAT SATELLITES
 
 Coverage Areas
 
  PAS-1 and PAS-3 provide coverage of the Atlantic Ocean Region, and PAS-2
provides, and PAS-8 will provide, coverage of the Pacific Ocean Region. PAS-5
and PAS-6 will provide additional coverage of the Atlantic Ocean Region and
PAS-4 provides, and PAS-7 will provide, coverage of the Indian Ocean Region.
PanAmSat is the first private company to provide global (excluding domestic
U.S.) satellite services. Accordingly, customers are able to contract solely
with PanAmSat for all of their international satellite needs.
 
  Construction of PAS-6 has been completed and it has been delivered to the
launch site. PAS-5 and PAS-7 are under construction and their designs are
complete. The coverage areas of PAS-8 are in the design stage and therefore
are subject to change. The coverage areas of a satellite are determined by the
shape of the satellite beams and are not alterable after launch. However,
certain of the transponders on PAS-2, PAS-3, PAS-4, PAS-6, PAS-7 and PAS-8 may
be transferred from one beam to another if market conditions warrant and PAS-5
has a moveable beam that can be focused over different regions.
 
                                      105
<PAGE>
 
                                     PAS-1
 
  PAS-1 provides four separate C-band coverage beams for all or parts of Latin
America and two Ku-band beams, one for the United States and one for Europe.
 
  One PAS-1 C-band beam provides nearly complete coverage of Latin America and
reaches the southern United States. Until March 1993, when PanAmSat began to
use CDV technology, all of the long-term capacity on this beam was sold out.
See "--Services--Video Distribution." As of December 1996, full-time
broadcasters and programmers who use this beam included Cinecanal, ESPN, NBC,
USA and VCC.
 
  The three other PAS-1 C-band beams focus coverage on different parts of Latin
America. As of December 1996, programmers using these beams on a full-time
basis included Cinecanal, CTC, HBO Ole, channels 2, 4, 5 and 13 (Peru), Sony,
Telefe (Argentina), Television Nacional de Chile and Warner Bros. These C-band
beams are also used for business communications services by Citicorp, Reuters,
Credit Suisse, Pacific National Bank and others. Carriers that use PAS-1
include Telegan, S.A. of Colombia and Impsat of Argentina. The PAS-1 Ku-band
beams are used for broadcasting and business communication services between the
United States and Europe. Customers for this service include BBC, CBS News and
NHK.
 
  Upon the commencement of PAS-3 services on February 19, 1996, PanAmSat
started implementing a plan to migrate some broadcast customers from PAS-1 to
PAS-3, thereby providing additional PAS-1 capacity for business communications
services.

<PAGE>
 
                                     PAS-2
 
  PAS-2 contains two C-band beams. These beams enable broadcasters to
distribute programming throughout Asia, Australia and New Zealand. One of these
beams also reaches across the Pacific Ocean to the western coasts of Canada and
the United States. Prior to the launch of PAS-2, U.S. programmers had to use
one satellite to cross the Pacific Ocean and another to distribute programming
within Asia. Because of PAS-2's coverage and high transmission power, North
American broadcasters can now distribute programming directly via PAS-2 from
the United States to Asia, and Asian broadcasters can distribute their
programming throughout Asia to North America. For instance, ESPN and Viacom are
using PAS-2 for United States-to-Asia program distribution, while ABS-CBN
(Philippines) is using PAS-2 for intra-Asian distribution and access to the
U.S. cable market.
 
  Three Ku-band beams on PAS-2 provide high-powered coverage that is focused on
Korea, Japan, China, including Hong Kong and Taiwan, Australia and New Zealand.
For instance, Television Broadcasting International and Taiwan Asia Space Cable
are using PAS-2 Ku-band capacity for high-power program distribution services
throughout Taiwan.

                                     PAS-3
 
  PanAmSat has established PAS-3, in conjunction with PAS-1, as the leading
satellites for cable and television programming distribution in Latin America.
Certain broadcasting customers on PAS-1 have moved to PAS-3, and the resulting
available capacity on PAS-1 is being used primarily for broadcasting and
business communications services in Latin America. PAS-3's two C-band beams
provide nearly total coverage of North America, South America, Western Europe
and Africa. This coverage creates new options for broadcast distribution among
these four continents as well as expanding channel capacity in Latin America.
 
  As of December 1996, PAS-3 customers for Pan-American C-band broadcast
services included Arab Radio and Television, Artear (Argentina), BBC, Bravo,
Caracol, China Central Television, Country Music Television, Discovery, ESPN,
20th Century Fox, HBO Ole, Liberty, NBC, Teledifusora Paraguaya, Televisa, TVN,
TV-5, Universidad Catolica and The Weather Channel. In addition, PAS-3 will
serve as an initial platform for the introduction of Latin America DTH services
offered by the Latin America JVs. It is also anticipated that PAS-3 will serve
as the platform for the Spain Transponder Agreement.

                                     PAS-4
 
  PAS-4 provides extensive coverage of the Indian Ocean Region with three C-
band and five Ku-band beams. The three C-band and five Ku-band beams provide
coverage of most of Europe, Africa, India and Asia, the Middle East and
Australia. The Ku-band transponders offer communications services to key
regions of economic activity including southern Africa, Far East Asia, Europe,
India and the Middle East. Due to the satellite's strategic orbital location
and the satellite's design, PanAmSat's customers are able to access the
satellite from as far east as Tokyo and as far west as Great Britain.
 
  PAS-4 links together key regions of the world for broadcast distribution,
business communications and telephony services. For instance, broadcasters in
Europe using PAS-4 are able to reach the Far East and Australia directly over
one satellite.
 
  Broadcast customers that use C-band capacity on PAS-4 for program
distribution in south Asia include Asia Business News, the BBC, China Central
Television, Discovery, Disney, Doordarshan, ESPN, HBO, Liberty, Home TV, Jain
TV, Sony, Turner Broadcasting and Viacom. Customers that use C-band capacity
for pan-African program distribution include M-Net/MultiChoice for its
multichannel digital C-band pan-African DTH platform and Viacom. In addition,
M-Net/MultiChoice and SABC/Sentech use PAS-4 Ku-band capacity to provide DTH
services in South Africa.

  PAS-5 will be a high-powered satellite and will contain 24 Ku-band and 24 C-
band transponders. Twelve of the satellite's 24 Ku-band transponders will be
used by the Latin America JVs to provide DTH services in Mexico, the Caribbean
and the southern United States. The C-band transponders have been designed to
provide coverage for broadcast distribution and other services in North
America, South America and Europe. It is anticipated that PAS-5 will serve as a
platform for the Latin America DTH Services offered by the Latin America JVs.

  PanAmSat has designed PAS-6 to provide DTH services in Latin America. All 36
transponders will be used by the Latin America JVs to provide DTH services in
Latin America. Subject to FCC approval, PanAmSat plans to co-locate PAS-6 with
PAS-3. It is anticipated that PAS-6 will serve as the main platform for the DTH
Services offered by the Latin America JVs.

  PAS-7 will be a high-powered satellite providing service over the Indian
Ocean Region. PAS-7 is expected to contain 14 C-band and 30 Ku-band
transponders and to be co-located with PAS-4. PAS-7 has been designed to expand
upon the DTH, broadcast and business communications services that are offered
on PAS-4. See "RISK FACTORS--Regulatory Risks."

  PAS-8 will be a high-powered satellite providing service over the Pacific
Ocean Region. PAS-8 is expected to contain 24 C-band and 24 Ku-band
transponders. PanAmSat's strategy with PAS-8 is to expand upon the broadcast
and business communications services that are offered on PAS-2. PAS-8 is in
the design stages and subject to change.

(1) PAS-1 was launched in June 1988 and commenced commercial service in
    November 1988. PAS-2 was launched in July 1994 and commenced commercial
    service in August 1994. PAS-4 was launched in August 1995 and commenced
    commercial service in September 1995. PAS-3 was launched in January 1996
    and commenced commercial service in February 1996. Future launch dates are
    based on PanAmSat estimates.
(2) PanAmSat has entered into a contract with SS/Loral for the construction
    and delivery of PAS-6, PAS-7 and PAS-8, with options to purchase
    additional satellites and/or replacement satellites for PAS-7 or PAS-8.
    PAS-6 has been delivered to the launch site. However, SS/Loral has
    recently informed PanAmSat of circumstances that could result in a delay
    in the launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess Weight."
    The contract contemplates delivery of PAS-7 in 1997 and PAS-8 in 1998.
(3) The information for PAS-1, PAS-2, PAS-3 and PAS-4 is based on fuel level
    estimates at January 31, 1997. The information for PAS-5, PAS-6, PAS-7 and
    PAS-8 is based on the terms of their satellite contracts, current mass
    projections and their launch contracts. Based upon current launch vehicle
    capabilities, each of PAS-5, PAS-6 and PAS-8 may have sufficient fuel to
    achieve a significantly longer life, in excess of 20 years. The
    construction design life of each satellite remains 15 years, which
    conservatively is the basis for the predicted life specified above. PAS-7
    also has a design life of 15 years, but SS/Loral has informed PanAmSat
    that it is expected to exceed its contractual weight specifications. To
    ensure that the excess weight does not affect the satellite's intended
    operational lifetime, PanAmSat is exploring several options, including
    satellite modifications by SS/Loral or the use of an alternative Ariane IV
    launcher configuration to deploy the spacecraft.
(4) The application for PAS-5 is pending with the FCC. PanAmSat has received
    conditional regulatory approval for PAS-6, which approval is subject to
    full financial showing and demonstration of consultation with Intelsat.
(5) PanAmSat has requested FCC approval to co-locate PAS-6 with PAS-3.
    PanAmSat expects to receive final authorization from the FCC to locate
    PAS-6 at 43(degrees) W.L. prior to its anticipated launch.
(6) PanAmSat has received conditional regulatory approval for the orbital slot
    of 72(degrees) E.L. from the FCC, which approval is subject to a full
    financial showing and demonstration of consultation with Intelsat. In
    addition, PanAmSat has requested approval to co-locate a satellite with
    PAS-4 at 68.5(degrees) E.L. PanAmSat intends to locate PAS-7 at the
    68.5(degrees) E.L. orbital location if its application for such orbital
    location is granted, in which case the 72(degrees) E.L. orbital slot could
    be used for another satellite. PanAmSat tentatively plans to locate PAS-8
    at 194(degrees) W.L. and has an application for that orbital slot pending
    with the FCC.
(7) Satellite transponders receive transmissions from Earth and relay them
    back to Earth. Transponders are composed of receivers, preamplifiers,
    power amplifiers, frequency shifters and a host of other electronics. C-
    band and Ku-band are ranges of frequencies used worldwide for commercial
    satellite communications. The C-band frequency is widely used for the
    distribution of television programming. The Ku-band frequency is widely
    used for DTH television broadcasting, satellite news-gathering
    applications and on-site business communications networks that require the
    use of very small antennas. Construction of PAS-6 has been completed and
    it has been delivered to the launch site. However, SS/Loral has recently
    informed PanAmSat of circumstances that could result in a delay in the
    launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess Weight." The
    designs of PAS-5 and PAS-7 are complete. The design for PAS-8 is still to
    be completed.
(8) Bandwidth is one measure of the information carrying capacity of a
    transponder. A transponder's bandwidth and power together determine the
    amount of information that can be carried. Construction of PAS-6 has been
    completed and it has been delivered to the launch site. However, SS/Loral
    has recently informed PanAmSat of circumstances that could result in a
    delay in the launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess
    Weight." The designs of PAS-5 and PAS-7 are complete. The design for PAS-8
    is still to be completed.
(9) Output power is the transmitter power of each transponder and is not a
    measure of the signal power received on Earth. Total output power is the
    aggregate power of all the transponders on the satellite. High output
    power allows for the use of smaller and less expensive receiving antennas
    to obtain the satellite signal. Construction of PAS-6 has been completed
    and it has been delivered to the launch site. However, SS/Loral has
    recently informed PanAmSat of circumstances that could result in a delay
    in the launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess Weight."
    The designs of PAS-5 and PAS-7 are complete. The design for PAS-8 is still
    to be completed.

 Types of Satellites
 
  PAS-1 is a GE Series 3000 satellite with 12 36-MHz and six 72-MHz
transponders at C-band and six 72-MHz transponders at Ku-band. The satellite
offers coverage of the Americas and Europe. PAS-1 was launched in June 1988
and has an expected in-orbit life of 13.25 years from the date of launch. PAS-
1 has not experienced any anomalies that have affected or which are expected
to affect the satellite's continued operation through its projected end-of-
life. In late 1989, PAS-1 experienced a loss of approximately one half of the
power on one transponder. A spare amplifier was switched over to the
transponder which effectively restored the lost power. No problems occurred
during the switchover, and this transponder currently meets all performance
specifications. In November 1992, PAS-1 experienced a loss of approximately
one half the power on another transponder in the same transponder bank. A
spare amplifier was not available because the spare amplifier assigned to the
transponder bank had already been switched to the transponder which
experienced power loss in late 1989. However, the transponder which
experienced the power loss in November 1992 continues to meet the performance
requirements under PanAmSat's contracts with the two customers which are using
this transponder, and PanAmSat has given these customers a nominal one-time
credit related to this loss of power. See "--Insurance."
 
  PAS-2 and PAS-3 are Hughes HS 601 satellites, each with 12 54-MHz and four
64-MHz transponders at C-band and 12 54-MHz and four 64-MHz transponders at
Ku-band. PAS-2 offers coverage of Asia and western North America. PAS-3 offers
coverage of the Americas, Europe and Africa. PAS-2 was launched in July 1994
and has an expected in-orbit life of 15 years from the date of launch. PAS-2
has not experienced any anomalies that have affected or which are expected to
affect the satellite's continued operation through its projected end-of-life.
In February 1995, the satellite experienced a brief outage on one transponder
amplifier and a spare amplifier was switched over. An additional amplifier
experienced a loss of gain in January 1996 and a spare amplifier was switched
over. No problems occurred during these switchovers, and these transponders
currently meet all performance specifications. PAS-3 was successfully launched
in January 1996, and commenced service in February 1996. PAS-3 has an in-orbit
expected life of 14 to 15 years from the date of launch. During in-orbit
testing, a Ku-band amplifier on PAS-3 was determined to be defective and a
spare amplifier was switched over.
 
  PAS-4 is a Hughes HS 601 satellite with 12 54-MHz and four 64-MHz
transponders at C-band and 16 27-MHz and eight 54-MHz transponders at Ku-band.
PAS-4 offers coverage of Europe, Africa, India and Asia, the Middle East, and
Australia. PAS-4 was successfully launched in August 1995 and commenced
service in September 1995. PAS-5 is also a Hughes HS 601 satellite designed to
meet PanAmSat's operational requirements. PAS-6 was constructed by SS/Loral.
 
  The design of PAS-5 is complete and construction has commenced. PAS-5 is
expected to carry 24 36-MHz transponders at Ku-band and 24 36-MHz transponders
at C-band. PanAmSat expects that the satellite will be able to carry 96 to 120
digital program channels over Ku-band transponders for reception within the
satellite's coverage area by households equipped with 24-36 inch (60-90 cm)
antennas. The satellite also can be used for other broadcast and business
communications services employing small, low-cost antennas on the ground.
Construction of PAS-6 has been completed and it has been delivered to the
launch site. However, SS/Loral has recently informed PanAmSat of circumstances
that could result in a delay in the launch of PAS-6. See "RISK FACTORS--Risk
of Delays; Excess Weight." PAS-6 will carry 36 36-MHz transponders at Ku-band
that will be able to carry 288 to 360 digital program channels. PanAmSat has
contracted with SS/Loral to build PAS-7 and PAS-8. PAS-7 has been designed to
contain 14 36-MHz C-band and 30 36-MHz Ku-band transponders. PAS-8 is expected
to contain 24 36-MHz C-band and 24 36-MHz Ku-band transponders. PAS-8 is in
the design stages and subject to change.
 
  When launched, each of PanAmSat's new satellites will have at least five
times (twelve times in the case of PAS-6) the transmission power of PAS-1.
This added power will allow PanAmSat and its customers to reduce their ground
segment costs significantly by allowing the use of smaller earth stations.
 
  The new satellites will offer a high-powered, multi-beam design. The
provision of both C-band and Ku-band capacity on each satellite, except for
PAS-6, will give PanAmSat flexibility to meet its customers' needs for
domestic, regional and international communications services.

  The C-band frequency is widely used for the distribution of television
programming. C-band is optimal for areas with relatively low levels of
microwave interference or relatively high levels of rainfall and in markets
which have a tolerance for a range of earth station sizes. C-band is currently
widely used in South America, Asia, Africa and the United States.
 
  The Ku-band frequency is widely used for DTH television broadcasting,
satellite news gathering applications and on-site business communications
networks that require the use of very small antennas. Ku-band is optimal for
areas with high levels of terrestrial microwave interference and where small
earth stations are required due to zoning or other physical considerations or
market needs. Ku-band is utilized throughout Europe, Australia and Japan and,
increasingly, in North America.
 
 The HAC PAS-5 Contract
 
  PanAmSat has contracted with HAC for the construction and delivery of PAS-5
(the "HAC PAS-5 Contract"). The HAC PAS-5 Contract calls for the delivery to
support an early May 1997 launch. HAC has notified PanAmSat that construction
is delayed and that HAC will be able to support a launch no earlier than late
June 1997. After a specified grace period, there will be liquidated damages
payable by HAC in the event of a late delivery which is the fault of HAC.
Payments representing approximately 80% of the total cost of the satellite
will be made during the period of the satellite's construction and upon
completion of the satellite's in-orbit testing with the remainder of such
costs to be paid in the form of incentive payments based upon the satellite's
orbital performance over the 15-year period following launch. PanAmSat has the
option of prepaying the incentive obligations at any time. The incentive
obligations are subject to reduction or refund if the satellite fails to meet
specific technical operating standards. The HAC PAS-5 Contract provides for a
limited pre-launch warranty by HAC which requires HAC to correct or replace
any non-conforming goods with conforming goods, if such correction or
replacement can be reasonably accomplished as determined by HAC. If the
delivery is delayed due to the fault of PanAmSat, PanAmSat will be obligated
to pay to HAC its reasonable costs incurred as a result of the delay plus a
profit component.
 
 The SS/Loral Satellite Contract
 
  PanAmSat has contracted with SS/Loral for the construction and delivery of
PAS-6, PAS-7 and PAS-8, and for the option to purchase up to two additional
satellites and up to four spare satellites (the "SS/Loral Satellite
Contract"). The SS/Loral Satellite Contract calls for the delivery of PAS-6,
PAS-7 and PAS-8 no later than November 10, 1996, August 4, 1997 and February
21, 1998, respectively. Despite the specified November 10, 1996 delivery date,
PAS-6 was delivered to the launch site in March 1997. However, SS/Loral has
recently informed PanAmSat of circumstances that could result in a delay in
the launch of PAS-6. See "RISK FACTORS--Risk of Delays; Excess Weight."
PanAmSat expects completion and delivery of PAS-7 in December 1997 followed by
an anticipated launch in the first quarter of 1998. In addition to the revised
delivery schedule, SS/Loral has informed PanAmSat that it expects that the
satellite will exceed its contractual weight specifications. To ensure that
the excess weight does not affect the satellite's intended operational
lifetime of approximately 15 years, PanAmSat is exploring several options,
including satellite modifications by SS/Loral or the use of an alternative
Ariane IV launcher configuration to deploy the spacecraft. There are limited
liquidated damages payable by SS/Loral in the event of a late delivery that is
the fault of SS/Loral and reductions in price that are specified for excess
weight. Payments representing approximately 80% of the total cost of the
satellite will be made during the period of the satellite's construction and
upon completion of the satellite's in-orbit testing with the remainder of such
cost to be paid in the form of incentive payments based on orbital performance
which will be made over the 15-year period following launch. PanAmSat has the
option of prepaying the incentive obligations at any time. The incentive
obligations are subject to reduction or refund if the satellite fails to meet
specific technical operating standards. The SS/Loral Satellite Contract
provides for a pre-launch warranty by SS/Loral which requires that the
satellite be free from defects and perform in accordance with technical
specifications.

LAUNCH ARRANGEMENTS
 
 Launch Services for PAS-5, PAS-6, PAS-7, PAS-8 and Future Satellites
 
  PanAmSat expects to launch PAS-5 and PAS-8 on a Proton launch vehicle, PAS-6
on an Ariane IV launch vehicle and PAS-7 on an Ariane IV or Ariane V launch
vehicle. Arianespace has had a successful launch rate of approximately 93%
since it began operations in May 1984 and an approximately 95% success rate
with the Ariane IV launch vehicle. The Ariane V is Arianespace's latest-
generation launch vehicle and is capable of carrying heavier payloads. The
first experimental launch of Ariane V suffered a launch failure on June 4,
1996. Arianespace is going forward with the development of Ariane V, but the
timing of the availability of Ariane V for commercial launches is uncertain.
In addition, on November 17, 1996, a Proton launch vehicle suffered a launch
failure, the second such failure in 1996. Preliminary indications are that the
failure may have been caused by the satellite and not the launch vehicle, and
as such PanAmSat does not believe that such failure will cause any delay to
future PanAmSat or Proton launches. An investigation of the failure has
commenced, but a final report has not been issued. Detailed information about
the nature of the launch failure or whether it will have an impact on the
timing of the launch of PAS-5 is not currently available.
 
  PanAmSat has entered into a contract with Arianespace for the launch of PAS-
6, which is expected to be launched from Arianespace's launch base in French
Guiana. In connection with the delayed delivery of PAS-6, PanAmSat has amended
its launch agreement with Arianespace to specify an April 1997 launch slot (or
earlier if both PanAmSat and Arianespace can accommodate it) for PAS-6.
However, Arianespace has informed PanAmSat that because of a delay in its
preceding launch with another customer, the launch of PAS-6 will likely be
delayed until May 1997. If PAS-6 is required to be returned to SS/Loral,
rescheduling of the launch of PAS-6 with Arianespace will be required.
 
  In December 1995, PanAmSat signed a multi-launch service contract with
Arianespace for one firm launch, which PanAmSat currently plans to use for
PAS-7, and rights for additional launches. PanAmSat has exercised its rights
for an additional launch in late 1999 or early 2000 for an unspecified
satellite. Arianespace has indicated its ability to provide a first quarter
1998 launch to accommodate the delay in the construction of PAS-7. It may be
possible to negotiate an agreement with Arianespace for a more powerful
launch, but there can be no assurance that PanAmSat will be able to reach
agreement with Arianespace on the terms or timing of a more powerful launch
than currently specified in PanAmSat's launch contract.
 
  PanAmSat has entered into an agreement (the "LKE Launch Contract") with LKE
which provides for launch services on the Proton launch vehicle. The Proton,
which is built in Russia and launched in Khazakhstan, has a reliability rate
of 94% over the last 50 launches. If the Proton is unavailable due to
technical, regulatory or other factors, LKE would provide launch services for
at least one launch using an alternative launch vehicle. See "RISK FACTORS--
Risks of Launch Failure." The LKE Launch Contract provides for the launch of
three of PanAmSat's satellites. It is anticipated that two of these launches
will be used for PAS-5 and PAS-8. PanAmSat and LKE have agreed to a revised
launch schedule for PAS-5 for July 1997.
 
  PanAmSat has reached agreements with SS/Loral, Arianespace and LKE that will
give PanAmSat contractual rights for the construction and launch of
replacement satellite(s) within 12 months or less of the launch failure of any
one or more of PAS-5, PAS-6, PAS-7 or PAS-8, in all cases in less time than it
took for the replacement satellite for PAS-3 to be constructed and launched
after the original satellite suffered a launch failure. Based upon provisions
that PanAmSat has been able to negotiate in contracts for its existing in-
orbit satellites and negotiations thus far with respect to services for its
future satellites, PanAmSat believes that these contractual rights for
replacement satellite(s) will allow it to retain its anticipated customer
contracts for these satellites in most circumstances (as was the case when
PAS-3 suffered a launch failure), including in the event of a launch failure.
However, any further delay to the launch of PAS-5 (more than currently
anticipated) could mean that replacement satellites, if required, would not be
available in time to avoid certain customers' rights to terminate their
contracts with respect to such satellites. Moreover, if PAS-6 is returned to
the manufacturer, as described above under the section captioned "RISK
FACTORS--Risk of Delays; Excess Weight,"
 
                                      116
<PAGE>
 
it would be unlikely, if there is a launch failure of PAS-6, that a
replacement satellite could be launched in time to avoid the termination
rights of the PAS-6 customer contracts.
 
  The launch contracts provide that PanAmSat may terminate such contracts at
its option, and the contracts include termination liability schedules that
increase in magnitude as the timing of any such termination approaches the
date of launch. The maximum liability, calculated in accordance with such
schedules, for launch services that have been ordered in connection with any
individual launch (including postponement fees) is approximately $45.0
million. Payments made by PanAmSat prior to PanAmSat's election to terminate
any such launch contract are offset against any such liability owed. The
launch contracts also contain rights for replacement launches in the event of
launch failures within specified periods following request for relaunch.
 
 Control of Satellites After Launch
 
  Once a satellite is placed at its orbital location, ground stations control
it until the end of its in-orbit lifetime. PAS-1 is controlled under a long-
term TT&C agreement by GE Capital Spacenet Services, Inc. from PanAmSat's
earth station facility located in Ellenwood, Georgia. PanAmSat has an
agreement with HCSS (and, in the case of PAS-5, with HAC) whereby HCSS will
provide TT&C services for PAS-2, PAS-3 and PAS-5 from HCSS facilities, which
will employ, in some cases, earth station facilities to be supplied by
PanAmSat. HCSS presently provides TT&C services for twelve satellites in
orbit. See "CERTAIN TRANSACTIONS." PanAmSat has an agreement with Optus
Networks Pty Limited ("Optus"), a leading supplier, for the provision of TT&C
for PAS-4. Optus is a recognized provider of such services with experience in
maintaining Hughes' satellites in orbit at locations that are outside of the
look angle of Hughes' U.S. facilities. PanAmSat and SS/Loral have an agreement
pursuant to which SS/Loral would provide TT&C service for PAS-6, PAS-7 and
PAS-8.
 
INSURANCE
 
  Under the satellite construction contracts, the contractor generally bears
the risk of loss of a satellite during the construction phase up to the
delivery, at which time title and risk of loss pass to PanAmSat (at which time
the launch insurance will become operative).
 
  In January 1996, PanAmSat obtained launch insurance for the construction,
launch and insurance costs for future satellites at a contracted premium rate
of 16% of the amount insured for PAS-5, PAS-6, PAS-7 and PAS-8. In April 1996,
PanAmSat obtained launch insurance for the construction, launch and insurance
costs at a contracted premium rate of 16% for PAS-9/R. The Certificate of
Designation (the "Certificate of Designation") for the PAS Preferred Stock
contains, and the Indenture (the "Exchange Indenture") relating to PanAmSat's
12 3/4% Senior Subordinated Notes due 2005 (the "Exchange Debentures") would
contain covenants requiring PanAmSat to obtain launch insurance for PAS-5 and
PAS-6 sufficient to cover the estimated cost of construction, launch and
launch insurance for a replacement satellite in the event of a total launch
failure up to a maximum of $230 million. Coverage under PanAmSat's launch
insurance will include claims arising from occurrences up to 180 days after
the launch. As a general matter, however, PanAmSat anticipates that the
insurance coverage will include not only catastrophic loss of a satellite
during launch but also the failure of a satellite to obtain proper orbit or to
perform in accordance with specifications once in orbit. If 50% or more of a
satellite's capability is lost, then a constructive total loss is deemed to
have occurred, and the full amount of insurance would become due and payable.
If the satellite is able to achieve more than 50% but less than 85% of its
performance specifications, PanAmSat will be entitled to a portion of the
amount of the insurance after taking into account a deductible equivalent to
no more than 15% of the satellite's capability. Losses are measured in
transponder years with Ku-band transponders weighted as 1.25 times the value
of C-band transponders.
 
  The insurance policies include standard commercial launch insurance
provisions and customary exclusions including (i) military or similar actions,
(ii) laser, directed-energy or nuclear anti-satellite devices,
(iii) insurrection and similar acts or governmental action to prevent such
acts, (iv) governmental confiscation, (v) nuclear reaction or radiation
contamination, (vi) willful or intentional acts of PanAmSat or its
contractors, (vii) loss of market, loss of revenue, extra expenses, incidental
and consequential damages, and (viii) third-party claims against PanAmSat.
 
                                      117
<PAGE>
 
  Over the period from 1989 to 1996, the risk of an insured commercial
satellite failing prematurely due to, among other things, mechanical failure,
a collision with objects in space or an inability to maintain proper orbit,
was approximately 1.6%. In-orbit insurance is typically purchased after a
satellite has been satisfactorily tested in-orbit, and coverage would commence
upon expiration of the launch insurance. The covenants under the Indenture
dated as of August 5, 1993 (the "Senior Secured Note Indenture"), among
PanAmSat, PanAmSat Capital Corporation ("PanAmSat Capital") and First Trust
National Association, as trustee, pursuant to which the Senior Secured Notes
were issued, and the Indenture dated as of August 5, 1993 (the "Discount Note
Indenture," and together with the Senior Secured Note Indenture, the "1993
Indentures"), among PanAmSat, PanAmSat Capital and U.S. Trust Company of New
York, as trustee, pursuant to which the Discount Notes require PanAmSat to
maintain in-orbit insurance for PAS-1, PAS-2, PAS-3 and PAS-4 in specified
amounts. The Certificate of Designation requires, and the Exchange Indenture
would require, PanAmSat to maintain in-orbit insurance for PAS-1, PAS-2, PAS-
3, PAS-4, PAS-5 and PAS-6. As of December 31, 1996, PanAmSat carried
approximately $60.0 million of in-orbit insurance for PAS-1, $192.0 million of
in-orbit insurance for PAS-2 (which amount decreases on a straight-line basis
over the estimated useful life of the satellite), $219.8 million of in-orbit
insurance for PAS-3 (which amount decreases on a straight-line basis over the
estimated useful life of the satellite), and $216.5 million of in-orbit
insurance for PAS-4 (which amount decreases on a straight-line basis over the
estimated useful life of the satellite). PanAmSat is presently exploring its
insurance options with respect to in-orbit coverage of each of PAS-5 and PAS-6
and intends to obtain in-orbit insurance initially for approximately 96% of
the construction, launch and insurance costs of each satellite, as well as for
PAS-7, PAS-8 and PAS-9/R. PanAmSat renewed its in-orbit insurance on PAS-1 in
1996 at an increased contracted annual premium rate of 3.75% of the coverage
provided thereby. This increase is attributable to certain anomalies which
appeared in 1995 in the performance of one of the command receivers on PAS-1.
PanAmSat has put in place certain operational procedures which are designed to
prevent the recurrence of these anomalies. The contracted annual premium rate
for PAS-2, PAS-3 and PAS-4 in-orbit insurance is 2.15% of the coverage
provided thereby.
 
  Coverage under PanAmSat's in-orbit insurance will include claims arising
from occurrences subsequent to 180 days after the launch. The insurance
coverage includes the failure of a satellite to continue to perform in
accordance with specifications. If 50% or more of a satellite's remaining
capability is lost, then a constructive total loss is deemed to have occurred,
and the full amount of insurance would become due and payable. If the
satellite is able to maintain more than 50% but less than 90% of its
performance specifications, PanAmSat will be entitled to a portion of the
amount of the insurance after taking into account a deductible equivalent to
not more than 10% of the satellite's capability. PanAmSat's in-orbit policies
typically include customary commercial satellite insurance exclusions,
including, among other things, damage or loss caused by military actions or
acts of war, anti-satellite devices, government action, frequency interference
or nuclear reaction.
 
SALES AND MARKETING
 
  PanAmSat's sales and marketing activities are separated into three general
service areas: full-time program distribution; part-time and ad hoc broadcast;
and business communications and long-distance telephony.
 
  PanAmSat's Greenwich headquarters has a sales and marketing department for
each service area. PanAmSat also has sales and marketing offices in Coral
Gables, Florida, Sydney, Australia, London, England, Tokyo, Japan and
Johannesburg, South Africa, which provide integrated sales and marketing for
all three service areas in their respective regions. The senior executive
officers of PanAmSat have been directly involved in marketing to key
broadcasting and business communications customers.
 
COMPETITION
 
  PanAmSat competes with companies and organizations which own or utilize
satellite or terrestrial transmission facilities. Many of such entities have
greater financial resources than PanAmSat.
 
 Other Satellite Operators
 
  PanAmSat's largest competitor in the international satellite communications
industry is Intelsat. Intelsat's mandate, established by international treaty,
is to provide international satellite capacity on a non-discriminatory
 
                                      118
<PAGE>
 
basis to countries around the world. Since its formation in 1964, Intelsat's
primary business has been the provision of satellite capacity for long-
distance telephony circuits. Historically, Intelsat has made available only a
small fraction of its transponders on each of its satellites for broadcasting
services. Comsat is the U.S. signatory of Intelsat and is the exclusive
wholesale marketer of Intelsat satellite capacity in the United States.
 
  Intelsat's satellites have historically been general purpose, lower-powered
satellites designed to serve large areas with public telephone service
transmitted between large and expensive gateway earth stations. The technical
features of Intelsat's satellites have not been well suited for services such
as programming distribution and business communications networks, which
involve large numbers of small earth stations. Intelsat's marketing
flexibility is limited because it generally provides capacity directly to its
signatories who then market such capacity to their customers. This marketing
structure has hindered Intelsat from marketing directly to customers and has
greatly increased the administrative procedures and costs involved in
obtaining satellite services from Intelsat.
 
  In recent years, Intelsat has responded to international and regional
competition from private satellite systems by purchasing higher-powered
satellites, offering focused regional coverage and pursuing arrangements which
are designed to permit broader marketing and support of its services,
including establishing regional Intelsat offices. Intelsat has also begun to
shift away from its historical focus on international telephony services
towards providing television and business communications network services. For
example, in October 1994, Intelsat's assembly of parties decided on a
classification of its proposed DTH services that will make it easier for
Intelsat to provide DTH services. Intelsat currently operates satellites that
are capable of providing DTH services in Latin America and is considering the
purchase and launch of a dedicated DTH satellite to serve Latin America. In
December 1996, Intelsat approved a proposal to construct a satellite for DTH
services in the Asia-Pacific Region. There can be no assurance that Intelsat
will not obtain a competitive advantage over PanAmSat for broadcasting and
business communications services. In February 1996, Comsat and the Clinton
Administration agreed to submit a proposal regarding Intelsat restructuring
that would divide Intelsat into two separate entities through the creation of
a new Intelsat affiliate company. Comsat has been discussing the proposal with
other Intelsat signatories, but based on trade press reports it appears that
the proposal has little or no support outside the United States. Intelsat is
also considering other proposals and is expected to take up the issue of
restructuring at the 1997 meeting of its member governments. If the joint
proposal or any other proposal on restructuring is approved and an affiliate
company of Intelsat is established, this could result in increased competition
to PanAmSat.
 
  For regional television distribution outside the United States, broadcasters
use, among others, Arabsat (Middle East), Eutelsat (Europe), Astra (Europe),
AsiaSat and APStar (Asia), Columbia Communications Corp. (Atlantic and Pacific
Ocean regions), Orion Network Systems, Inc. ("Orion") (Atlantic Ocean region)
and Palapa (Southeast Asia) and, to a lesser extent, Intelsat. While these
entities are active in regions in which PanAmSat plans to provide facilities
and services, only Intelsat is a global system. Countries that have domestic
satellite systems include Argentina, Australia, Brazil, Canada, China, France,
Germany, India, Italy, Japan, Malaysia, Mexico, Russia, South Korea, Spain,
Thailand, Turkey and the United States. Argentina, Brazil, Malaysia, Mexico
and Thailand also provide regional services on their domestic satellites.
 
  For example, AsiaSat, a private regional satellite operator based in Hong
Kong, has granted an exclusive right for international program distribution on
its current AsiaSat-1 satellite to one broadcaster, StarTV. StarTV requires
broadcasters to distribute their programming under the StarTV name and also
requires broadcasters to share a portion of their revenues with StarTV.
AsiaSat-1 also offers satellite capacity for business communications and voice
services. In 1995, AsiaSat launched the AsiaSat-2 satellite on a Chinese
rocket and published reports indicate that AsiaSat has entered into a lease
for satellite capacity with StarTV which was also granted an exclusive right
for international programming distribution on AsiaSat-2.
 
 Proposed Satellite Systems
 
  Other companies have announced plans to operate regional or transoceanic
satellite systems. Entry into the international satellite communications
industry can be expensive and difficult. The construction and launch of a
 
                                      119
<PAGE>
 
satellite comparable to PanAmSat's new satellites usually takes approximately
three or more years and costs approximately $200 million to $250 million. In
addition, there are a limited number of orbital slots. The operation of an
international satellite communications system also requires approvals from
national telecommunications authorities and Intelsat and, in certain cases,
from regional satellite authorities, such as Eutelsat. See "--Government
Regulation." While the trend around the world is to liberalize these
regulatory requirements, at present obtaining the necessary licenses involves
significant time, expense and expertise.
 
  Orion has announced plans to construct and launch an additional satellite in
mid-to late-1997 in the Atlantic Ocean Region and a satellite thereafter in
the Asia-Pacific region.
 
  Two Japanese domestic satellite operators plan to provide regional service
throughout the Pacific Ocean Region. The first of three satellites was
launched in August 1995. In January 1996, GE Capital Satellites International
Inc. announced that the government of Gibraltar had filed applications on its
behalf with the ITU for 12 orbital slots in which to operate satellites
serving Africa, Asia and the Pacific Rim.
 
  Countries planning to launch domestic satellites include Egypt, Laos and the
Philippines.
 
 Service Providers
 
  A number of U.S.-based service providers offer business communications
services in competition with PanAmSat through Intelsat satellite capacity
including Comsat, MCI and Sprint. In addition, MCI and Sprint are users of
PanAmSat's satellites when they seek to use satellites for part or all of the
network services they offer their customers. Certain service providers, such
as Keystone Communications, utilize leased satellite capacity to provide
limited services to broadcasters, primarily for ad hoc applications.
 
 Optical Fiber Cables
 
  Optical fiber cables generally do not compete with PanAmSat's services. The
primary use of optical fiber cables is to carry high-volume telephony
communications on a point-to-point basis, a market PanAmSat does not intend to
enter. Transcontinental optical fiber cables currently carry video traffic,
but this service is largely for point-to-point traffic (e.g., New York to
London). Optical fiber cables are not readily usable for point-to- multipoint
broadcast applications or for the transmission of ad hoc events which require
short-term satellite capacity and transportable uplink earth stations. These
areas are expected to constitute the largest segments of PanAmSat's
broadcasting services.
 
 U.S. Domestic Satellites
 
  The FCC traditionally has not permitted U.S. domestic satellites to provide
international service except in limited circumstances. However, on January 22,
1996, the FCC released a decision permitting all U.S.-licensed satellites to
provide both domestic and international services without regard to whether the
satellites initially had been licensed as domestic satellites or separate
international systems. In practice, however, most existing U.S. domestic
satellites are designed to serve principally the United States. The FCC's
decision also authorized direct broadcast satellite systems licensed by the
FCC to provide international service.
 
GOVERNMENT REGULATION
 
  The international communications environment is highly regulated. As an
operator of a privately owned international satellite system, PanAmSat is
subject to the regulatory authority of the U.S. government (primarily the FCC)
and the national communications authorities of the countries in which it
operates. In addition, PanAmSat is subject to the Intelsat consultation
process as described below, which can result in the imposition of operational
restrictions on PanAmSat. While PanAmSat has all necessary licenses and
governmental approvals for the construction, launch and operation of PAS-1,
PAS-2, PAS-3 and PAS-4, there can be no assurance that PanAmSat will succeed
in obtaining all requisite regulatory approvals for PAS-5, PAS-6, PAS-7 and
PAS-8 and for the orbital slots planned for these satellites without the
imposition of operational restrictions on PanAmSat.
 
                                      120
<PAGE>
 
 U.S. Regulation
 
  The FCC is the governmental body with primary authority in the United States
over all satellite carriers.
 
 1. Licensing Terms
 
  PanAmSat is not regulated as a common carrier. As a non-common carrier,
PanAmSat is free to set prices and serve customers according to its business
judgment, without rate of return or price cap regulation or requirements not
to discriminate among customers, and with minimal governmental scrutiny of its
business decisions. PanAmSat is subject to the FCC's review primarily for: (i)
the licensing of individual satellites and earth stations (e.g., meeting
minimum financial, legal and technical standards); (ii) avoidance of
interference with other radio stations; and (iii) compliance with rules the
FCC has established specifically for U.S.-based international satellite
companies.
 
  PanAmSat's original license from the FCC prohibited it from carrying any
traffic to or from the United States that interconnected with a public
switched telephone network ("PSTN"). This restriction was designed to protect
Intelsat's public switched telephone services business from competition and
broadly precluded any separate international satellite company, such as
PanAmSat, from any connection, direct or indirect, into the PSTN on either
side of a circuit that enters or leaves the United States. Thus, a customer
could not terminate a private line carried by PanAmSat into a switchboard that
would switch the call into the PSTN, either in the United States or at the
other end of the circuit.
 
  In subsequent decisions, the FCC authorized PanAmSat to provide a wide range
of services involving the PSTN. In response to a petition filed by PanAmSat
with the FCC, and in recognition of changed conditions, the FCC in March 1992
modified this restriction to permit carriage of 1,250 64-kbps bearer circuits
of fully connected telephone traffic per satellite and stated its intention to
eliminate this restriction entirely by January 1, 1997. In March 1994, the FCC
reaffirmed the 1,250 64-kbps bearer circuit standard for public switched
services and authorized PanAmSat to provide an unlimited number of private
lines that are connected to the PSTN. The interconnected private lines are
subject to resale restrictions and to restrictions against using the
interconnected private lines to provide public switched telephone service. In
October 1994, Intelsat increased the threshold below which Intelsat presumes
private international satellite systems do not cause economic harm to 8,000
64-kbps bearer circuits per satellite. In November 1996, the FCC brought its
policies into line with this new standard, and effective January 1, 1997, the
FCC no longer restricts the number of public switched circuits that PanAmSat
may carry. For purposes of Intelsat consultation, however, the presumption
that private international satellite systems do not cause economic harm
continues to be limited to systems carrying 8,000 64-kbps bearer circuits or
less per satellite. The FCC's previous separate system policies restricted
PanAmSat's ability to provide U.S. domestic service, subject to certain
exceptions. On January 22, 1996, however, the FCC released a decision
abolishing those restrictions and also permitting all U.S.-licensed satellites
to provide international service.
 
  The FCC has granted PanAmSat Carrier Services, Inc. ("PCSI"), a wholly owned
subsidiary of PanAmSat, authority, pursuant to Section 214 of the
Communications Act of 1934, as amended (the "Communications Act"), to provide
international private line and public switched services via the PAS-1
satellite on a common carrier basis. Although PCSI is a common carrier,
PanAmSat will continue to operate as a non-common carrier.
 
 2. Authorization to Construct, Launch and Operate Satellites
 
  PanAmSat has conditional or final authorization from the FCC for a total of
five satellites. The U.S. government has filed with the ITU for, among other
things, all of PanAmSat's orbital slots for PAS-1 through PAS-8. See "--
International Telecommunications Union."
 
  PanAmSat is licensed by the FCC to operate PAS-1 in geostationary orbit at
45(degrees) W.L. PanAmSat is required to engage in frequency coordination with
other satellite operators. These include Orion Satellite Corporation, which
has an FCC authorization for an international satellite in the orbital
location adjacent to PAS-1. Orion has taken the position that PanAmSat must
accept interference from Orion's satellite because PAS-1 does not have "full
frequency reuse," while PanAmSat has disputed this position. The FCC has
suggested that Orion's position
 
                                      121
<PAGE>
 
is incorrect, but stated that it will not rule definitively on the issue
unless the parties are unable to resolve their differences by frequency
coordination. Orion announced in 1993 that it had canceled its contract for
construction of the satellite which was intended for this orbital slot but
reaffirmed its intention to build such satellite at an unspecified later date.
 
  PanAmSat is licensed to operate PAS-2 in geostationary orbit at 191(degrees)
W.L. PAS-2 was launched in July 1994.
 
  PanAmSat is licensed to operate PAS-3 in geostationary orbit at 43(degrees)
W.L. PAS-3 was launched in January 1996.
 
  PanAmSat is licensed to operate PAS-4 in geostationary orbit at
68.5(degrees) E.L. PAS-4 was launched in August 1995.
 
  PanAmSat has obtained conditional regulatory approval from the FCC to
construct, launch and operate PAS-6 at 43(degrees) W.L., where it would be co-
located with PAS-3 over the Atlantic Ocean Region in order to provide DTH
television services throughout Latin America.
 
  PanAmSat has obtained conditional regulatory approvals from the FCC to
construct, launch, operate and locate a satellite at 72(degrees) E.L. (over
the Indian Ocean Region), subject to a full financial showing and
demonstration of consultation with Intelsat. In addition, PanAmSat has
requested approval to co-locate a satellite with PAS-4. PanAmSat intends to
locate PAS-7 at the 68.5(degrees) E.L. orbital location if its application for
such orbital location is granted. PanAmSat has requested a waiver that would
enable its 68.5(degrees) E.L. co-located application to be processed under the
pre-existing separate system policies, rather than under recently-adopted new
FCC processing policies under which the FCC would not process the application
until it had completed processing of all domestic satellite and separate
system applications that were pending when the FCC adopted the new processing
policies on January 19, 1996. If these policies were to apply, then after the
FCC had finished processing pending applications it would issue a public
notice establishing a new processing round including the 68.5(degrees) E.L.
application and any other applications filed in response to the public notice.
Absent a waiver, therefore, processing could be substantially delayed beyond
the anticipated PAS-7 launch, which is scheduled for the third quarter of
1997. No delay would occur if PanAmSat elects to position PAS-7 at 72(degrees)
E.L.
 
  None of these final or conditional authorizations, as appropriate, is
subject to further administrative or judicial reconsideration or review. The
FCC reserves the right to require the repositioning of a satellite's orbital
slot if the FCC determines that it is in the national interest that such a
change be made. The FCC has rarely used this authority.
 
  PanAmSat's conditional construction authorizations, by themselves, do not
entitle PanAmSat to expend funds toward the construction of its satellites.
Accordingly, from time to time PanAmSat has requested and received waivers
pursuant to Section 319(d) of the Communications Act from the FCC permitting
such expenditures in specified amounts.
 
  PanAmSat also has pending FCC applications for the following satellites:
PAS-8, to be located at 194(degrees) W.L. (over the Pacific Ocean Region) and
PAS-5, to be located at 58(degrees) W.L. (to supplement the capacity of PAS-1
and PAS-3). PanAmSat may request approval to co-locate PAS-8 with PAS-2.
 
  Final FCC authorization for each of PanAmSat's satellites and orbital slots
is subject to demonstration that PanAmSat has sufficient funds to construct,
launch and operate the satellite for one year and completion of the Intelsat
consultation process with at least one country in addition to the United
States. The FCC recently revised its financial qualification requirements for
separate system applicants, requiring that such applicants make a full
financial showing at the time they file. The FCC's decision gives applicants
whose applications are already on file an opportunity to amend their
applications to conform to the new financial requirements. Applications that
were filed prior to April 25, 1995 are "grandfathered" and need not comply.
Applications that were filed after
 
                                      122
<PAGE>
 
that date and that specified "uncongested" portions of the orbital arc may,
upon "appropriate request," defer their full financial showing pursuant to the
two-step financial standard that previously was applicable to separate
systems. PAS-5 and PAS-8 are grandfathered under the new rules, and PanAmSat
has requested that PAS-6 and PAS-7 be processed under the pre-existing two-
step financial standard. PanAmSat therefore believes that these new financial
requirements will not materially affect its ability to obtain final authority
for PAS-5, PAS-6, PAS-7 and PAS-8. There can be no assurance, however, that
these new requirements will not materially affect the ability of PanAmSat to
obtain final authority for any future satellites.
 
  PanAmSat also has filed applications for satellites at 79(degrees) W.L.
(PanAmSat has informally requested that the FCC associate this application
with the 81(degrees) W.L. orbital location) and at 93(degrees) W.L. These
applications, as well as the applications and authorizations discussed above
for PAS-1 through PAS-8, all involve operations on C-band and Ku-band
frequencies. If these two applications are granted, the FCC would have to
assign different orbital locations because it since has assigned the
79(degrees) W.L. and 93(degrees) W.L. locations to other applicants. In
addition, PanAmSat has filed applications for nine Ka-band satellites. Two of
the nine applications were filed within the deadline for the first Ka-band
"processing group" and the FCC tentatively has assigned to PanAmSat the
orbital location it requested in one application subject to final action on
its application for the orbital location. Pursuant to an agreement among all
the Ka-band applicants that is subject to FCC approval, PanAmSat expects to be
assigned a second Ka-band orbital location. The remaining seven applications
were filed after the deadline, and the FCC's International Bureau denied
PanAmSat's request to reopen the initial Ka-band processing round. Unless that
decision is reversed on review or appeal, the seven applications might not be
processed until the FCC commences a second Ka-band processing round. The FCC
has an ongoing rulemaking process to determine on what basis it will authorize
applicants to construct, launch and operate satellites in the Ka-band.
 
  The frequencies that are intended to be used to uplink to PAS-7 and PAS-6
include frequencies in the 13.75-14.0 GHz band, which constitute approximately
33% of the frequencies of PAS-6 and approximately 80% of the Ku-band
frequencies on PAS-7. These frequencies must be coordinated with the U.S.
government on an earth-station-by-earth-station basis to insure that harmful
interference to primary government operations is minimized. PanAmSat presently
is undertaking such coordination and believes that it will be able to
coordinate successfully with federal government users. While PanAmSat believes
that it will successfully coordinate with such earth stations or will
institute operational solutions that will mitigate the problem, there can be
no assurance that PanAmSat's efforts will be successful. See "RISK FACTORS--
Regulatory Risks."
 
 3. Intelsat Consultation
 
  Prior to receiving final licensing and launch authority, and prior to
offering services between the United States and any overseas point, PanAmSat
has to complete a consultation with Intelsat under Article XIV of the Intelsat
Agreement. This requires arranging for the U.S. government and the appropriate
governmental authority in at least one overseas point to consult with Intelsat
to assure that use of the new satellite will cause Intelsat neither technical
harm arising from signal interference nor "significant economic harm."
Thereafter, in order to provide services involving additional countries, those
countries have had to associate with the prior Article XIV consultation. In
September 1994, Intelsat's board of governors eliminated the association
requirement. To provide domestic services in any country other than the United
States, PanAmSat need only make the technical showing. For PAS-1, the first
private international satellite to go through the process, the consultation
process was extremely difficult, as Intelsat initially took the view that any
separate system would cause significant economic harm. Over time, however,
Intelsat has modified its views. In November 1992, Intelsat adopted a
resolution indicating that it will no longer scrutinize for significant
economic harm any satellite services that do not connect with the public
telephone network or which do not provide more than 1,250 64-kbps bearer
circuits connecting to the PSTN per satellite. In October 1994, Intelsat
approved an increase in this limitation to 8,000 64-kbps bearer circuits per
satellite, and in November 1996, the FCC brought its policies into line with
this new standard. The FCC is responsible for ensuring that PanAmSat has
undergone the necessary consultation and that it operates in accordance with
the technical parameters forming the basis for an Article XIV consultation. If
PanAmSat changes the terms (either technical or service) of its operation in a
significant way, it may need to reconsult with Intelsat.

 Overseas National Telecommunications Authorities
 
  PanAmSat is the first private company to provide global (excluding domestic
U.S.) satellite services. Most countries where PanAmSat operates are
signatories of Intelsat. As a result, their national telecommunications
authorities may require confirmation that PanAmSat successfully completed
technical coordination with Intelsat before providing services on a given
satellite. Beyond this consultation, PanAmSat may be subject to national
communications and/or broadcasting laws. While these vary from country to
country, national telecommunications authorities have not typically required
PanAmSat to obtain licenses or regulatory authorizations in order to provide
space segment capacity to licensed entities. PanAmSat believes that Argentina,
Colombia and Pakistan are the only countries in which PanAmSat currently
operates that require national regulatory approval for the provision of space
services to licensed carriers. PanAmSat has obtained authorization from the
Argentine National Telecommunications Commission to provide services on PAS-1
and PAS-3 in Argentina, and has applied for authorization for PAS-6. Recent
changes in the law in Argentina, however, appear to limit the circumstances in
which non-Argentinian satellites may be used to provide certain satellite
services in Argentina. PanAmSat will oppose these measures vigorously to the
extent the measures are determined to apply to PanAmSat's satellite system.
There can be no assurance, however, that PanAmSat will be able to obtain the
authorizations needed to serve customers in Argentina in the future or to
avoid having its existing authorizations circumscribed in a manner that
adversely affects its ability to serve existing customers in Argentina.
PanAmSat has also received regulatory approval in Pakistan.
 
  National laws and regulatory practices governing access to satellite systems
vary substantially among countries. Many countries have liberalized their
national communications market, allowing multiple entities to seek licenses to
provide voice, data or video services for their own use or for third-party
use; to own and operate private earth station equipment; and to choose a
provider of satellite capacity. Many countries allow licensed radio and
television broadcasters and cable television providers to own their own
transmission broadcast facilities and purchase satellite capacity without
restriction. In such environments, customer access to PanAmSat's services can
be a relatively simple procedure. PanAmSat may provide services through one or
many licensed carriers or to end users of private network services directly.
Such liberalization policies have been adopted in most Latin American
countries and, increasingly, in Europe, Africa and Asia.
 
  In several countries, PanAmSat has chosen to apply to national
telecommunications authorities to obtain licenses for provision of services
directly to end users. In Ecuador, France, Germany, Japan and the United
Kingdom, PanAmSat has obtained licenses covering its operations which permit
PanAmSat to provide certain services directly to end users. In Colombia and
Peru, PanAmSat has requested from the national telecommunications authorities
its own licenses to service customers directly.
 
  Other countries, however, have maintained strict monopoly regimes, so that
end-users may be required to access PanAmSat's services through a single,
government owned entity. In such markets, the entity (often the Posts,
Telephone and Telegraph authority, or the "PTT") may hold a monopoly on
ownership and operation of facilities or on the provision of communications
and/or broadcasting services to, from and within a country, including via
satellite. In order to provide services in such environments, PanAmSat may be
required to negotiate an operating agreement with the PTT that describes the
types of services offered by each party, the contractual terms for service and
each party's rates. Depending on the national regulatory requirements, these
operating agreements may require that PanAmSat's services be obtained through
the PTT alone at a pre-arranged markup, with all associated ground services
provided by the PTT; or the operating agreement may allow customers to own and
operate their own facilities but purchase PanAmSat's services through the PTT
at a rate reflecting the pre-arranged markup.
 
  Notwithstanding the wide variety of regulatory regimes extant in the
countries where PanAmSat currently provides service, PanAmSat believes that
PanAmSat and its customers are in compliance in all material respects with all
applicable laws and regulations governing its operations.
 
 International Telecommunications Union
 
  Nations are required to register their proposed use of orbital slots with
the Radio Regulations Board of the ITU (formerly the International Frequency
Registration Board) (the "ITU Radio Regulations Board") to ensure
 
                                      124
<PAGE>
 
that there is an orderly process for accommodating each country's needs for
orbital locations. After a nation has advised the ITU Radio Regulations Board
of its desire to use a given orbital location at a given frequency, other
nations may give notice of their use or intended use in a manner that would
conflict with the first proposal. The nations are then obligated to negotiate
in an effort to coordinate the proposed uses and resolve interference
concerns. The FCC takes responsibility for filing and coordinating PanAmSat's
orbital slots with the ITU Radio Regulations Board. If all disputes are
resolved, the nations requesting proposed uses may be formally notified,
which, theoretically, provides interference protection from subsequent or
nonconforming uses. The ITU Radio Regulations Board has no dispute resolution
or enforcement mechanisms, however, and if the nations cannot agree upon a
coordination or upon resolution of an interference problem, there are no clear
remedies under international law. Although PAS-1 has been operating since
1988, Brazil has not yet withdrawn certain objections which it raised to PAS-
1's orbital slot, and, accordingly, the FCC has never received final
notification from the ITU Radio Regulations Board that PAS-1's orbital slot
has been finally registered. PanAmSat believes that Brazil's objections will
not adversely affect PanAmSat's ability to continue to operate PAS-1.
 
  The government of Papua New Guinea and the government of Tonga have filed
notices of intended use that potentially conflict with the registrations for
PAS-2, PAS-4 and PAS-8. The government of Tonga has filed conflicting claims
for orbital slots with regard to other ITU Radio Regulations Board filings in
the past, but neither the government of Tonga nor the government of Papua New
Guinea (whose filing that potentially conflicts with PAS-2 dates back to the
mid-1980s) has ever launched a satellite. On September 12, 1994, however, an
agreement was announced between an agent of Tonga and APT Satellite to locate
APStar-1 at 138(degrees) E.L., an orbital location that Tonga had filed for at
the ITU. Moreover, Tonga has entered into a series of agreements with a start-
up company, Rimsat, that provides Rimsat access to the orbital locations
claimed by Tonga. Rimsat, in turn, has arranged to acquire various Russian
satellites to place in such locations. PanAmSat believes Rimsat placed two
Russian-built satellites over the Pacific Ocean at 134(degrees) E.L. and
130(degrees) E.L., neither of which conflicts with orbital locations reserved
for PanAmSat. Tonga and Rimsat, however, have announced similar arrangements
that would place Russian satellites at 70(degrees) E.L., which could conflict
with PAS-4's slot of 68.5(degrees) E.L., and at 189.25(degrees) W.L., which
could conflict with PAS-2 at 191(degrees) W.L. Rimsat reportedly has defaulted
on its payments to Tonga and to the vendor of its Russian satellites, and
courts in Indiana and the island of Nevis, respectively, have appointed a
bankruptcy trustee and a receiver to manage Rimsat's affairs. The Russian
company from which Rimsat obtained its satellites reportedly has taken back
control of the satellites. Papua New Guinea filed with the ITU for a slot at
192.55(degrees) W.L. prior to the time that the FCC filed on PanAmSat's behalf
for PAS-2. PanAmSat believes the Papua New Guinea registration has expired but
Papua New Guinea claims its registration will remain valid for several years.
On June 16, 1993, PanAmSat filed an application with the FCC to change the
orbital location of PAS-2 from 192(degrees) W.L. to 191(degrees) W.L. , in
part to gain an additional degree of separation from the location claimed by
Papua New Guinea. Pacific Satellite, Inc. ("Pacstar"), a company that is owned
in part by Papua New Guinea and that claims rights to Papua New Guinea's
orbital location, filed a "Petition to Deny or in the Alternative to Condition
Approval on Showing of No Interference" against PanAmSat's application. The
FCC has denied the Pacstar petition. Pacstar's appeal to the United States
Court of Appeals for the District of Columbia was dismissed because it was
untimely. According to press accounts, Papua New Guinea and Loral Space and
Communications Ltd. ("Loral Space") entered into an agreement in early 1997
under which Loral Space would build and place three satellites into orbital
locations claimed by Papua New Guinea, including the 192.55(degrees) W.L.
orbital location, and Loral Space and Papua New Guinea would share capacity on
the satellites.
 
  In addition, a Russian government satellite operates at 70(degrees) E.L. Up
to one half of the C-band transponders on PAS-4 overlap in frequency with the
Russian satellite. PanAmSat, under the auspices of the U.S. government, has
attempted to coordinate the two satellites with Russian authorities. The
Russian authorities, however, have refused to provide full technical
information regarding the satellite, and claim that PAS-4 interferes with the
Russian satellite. The Russian authorities have filed a complaint with the ITU
and have requested that the U.S. authorities require PanAmSat to cease the
alleged interference. The U.S. government challenged the Russian authorities'
claim of interference and has urged the Russian authorities to provide
additional technical information regarding the satellite, and to proceed with
coordination. On November 8, 1996, the ITU declined to
 
                                      125
<PAGE>
 
take action on the Russian complaint and referred the matter to the U.S. and
Russian authorities for further coordination efforts. PanAmSat believes that
PAS-4 and the Russian satellite could be coordinated successfully with reduced
adverse effects on PAS-4 capacity. However, until coordination is completed
successfully, PanAmSat's ability to provide services in Russia or to Russian
customers will be affected adversely, both technically and politically. It is
PanAmSat's belief that Russia has taken the position that it will not license
within Russia the use of PanAmSat's satellites. If PAS-7 is to be co-located
with PAS-4, it is unlikely that PAS-7 will be permitted to operate its C-band
transponders for commercial use until the above described coordination issues
with Russia have been resolved successfully.
 
  In addition, after the registration for PAS-4 had been filed, Intelsat filed
in August 1993 with the ITU Radio Regulations Board for an orbital location
that could conflict with PAS-4's then-intended slot and Intelsat subsequently
announced plans to place a satellite near its end-of-life at that location.
PanAmSat reached an agreement with Intelsat pursuant to which PanAmSat was
able to occupy 68.5(degrees) E.L.; Intelsat can locate its end-of-life
satellite at 72(degrees) E.L. for a limited period and, at the conclusion of
that period, PanAmSat may bring a satellite into service at 72(degrees) E.L.
 
  PanAmSat's FCC application for PAS-5 includes requests to use the so-called
"planned band" frequencies. The U.S. planned band registration request for
PAS-6 specifies 45(degrees) W.L., and needs to be modified to specify
43(degrees) W.L. Although PanAmSat believes the FCC will approve operations at
43(degrees) W.L. as requested by PanAmSat, there can be no guarantee of such
approval or of successful registration at 43(degrees) W.L. in lieu of
45(degrees) W.L.
 
  The U.S. government has filed with the ITU for nine orbital slots for Ka-
band geostationary satellites, substantially all of which are sought by
PanAmSat and other U.S. applicants as well.
 
  All of the registrations for PanAmSat's satellites are or will be subject to
the ITU coordination process. The filings described above that conflict with
PanAmSat's registered slots may delay the receipt of final registration for
PAS-2's and PAS-4's orbital locations with the ITU Radio Regulations Board.
 
EMPLOYEES
 
  At December 31, 1996, PanAmSat had 210 full-time employees. The Engineering
and Operations department consists of 116 employees, all of whom, with the
exception of the senior vice-president of engineering and three marketing
support engineers, are based full-time at PanAmSat's teleports in Ellenwood,
Georgia, Homestead, Florida and Napa, California. The broadcasting, business
communications and new business development departments consist of 49 people.
There are 45 employees involved in providing administrative, accounting,
regulatory and public relations services. PanAmSat believes its relations with
its employees are good.
 
PROPERTIES
 
  PanAmSat's executive offices are located in Greenwich, Connecticut. PanAmSat
leases its executive offices pursuant to a lease that will expire on March 21,
2003. PanAmSat currently operates three teleports in conjunction with the PAS
Global System. PanAmSat operates its primary teleport in Ellenwood, Georgia
and operates regional teleports in Homestead, Florida for PAS-1 and PAS-3, and
in Napa, California for PAS-2. All of such teleports are manned 24 hours a
day. PanAmSat owns its Homestead, Florida teleport.
 
  PanAmSat also leases office space for its sales and marketing offices in
Coral Gables, Florida, Sydney, Australia, London, England and Tokyo, Japan.
PanAmSat's leases for its foreign offices have been entered into upon terms
that PanAmSat deems to be reasonable and customary.
 
LEGAL PROCEEDINGS
 
  In July 1989, PanAmSat and its then chairman, Rene Anselmo, filed an
antitrust lawsuit against Comsat, the U.S. signatory to Intelsat, in the
United States District Court for the Southern District of New York. In
September 1990, the District Court dismissed the complaint, primarily on the
ground that Comsat is immune
 
                                      126
<PAGE>
 
from suit for actions taken "in its role as the U.S. representative to
Intelsat." PanAmSat filed an appeal of the dismissal with the United States
Court of Appeals for the Second Circuit. In September 1991, the Second Circuit
reversed the dismissal and remanded the case to the District Court to permit
the filing of an amended complaint alleging conduct not shielded by immunity.
The amended complaint, which seeks substantial damages and injunctive relief,
was filed on November 15, 1991. Comsat moved to dismiss the amended complaint,
but on March 30, 1993, the court denied Comsat's motion and allowed PanAmSat
to proceed on all points it had raised in its amended complaint. The amended
complaint alleges anticompetitive conduct by Comsat, as well as actions by
Comsat in concert with others, to prevent or delay PanAmSat's entry into
various markets. On December 16, 1994, Comsat filed a summary judgment motion
and on March 1, 1995 PanAmSat filed papers in opposition to Comsat's motion.
On September 4, 1996, the District Court granted Comsat's motion for summary
judgment against PanAmSat. PanAmSat filed a notice of appeal on October 2,
1996. Briefs have been submitted to the court, but a date for a hearing has
not yet been set.
 
  On or about October 25, 1996, an action was commenced by Comsat against
PanAmSat, News Corp. and Televisa, in the United States District Court for the
Central District of California. The complaint alleges that News Corp.
wrongfully terminated an agreement with Comsat for the lease of transponders
on an Intelsat satellite over the term of a five-year lease, breached certain
alleged promises related to such agreement, and breached its alleged
obligations under a tariff filed by Comsat with the FCC. As to PanAmSat, the
complaint alleges that PanAmSat, alone and in conspiracy with Televisa,
intentionally interfered with the alleged agreement and with Comsat's economic
relationship with News Corp. Comsat had previously filed a similar action in
the United States District Court for the District of Maryland. By order dated
October 10, 1996 the Maryland District Court dismissed without prejudice the
complaint in that action on the ground that the court lacked personal
jurisdiction over all of the defendants. The complaint in the present action
seeks actual and consequential damages, and punitive or exemplary damages, in
an amount to be determined at trial but which Comsat alleges exceed $50,000.
On December 11, 1996, PanAmSat, News Corp. and Televisa filed motions to
dismiss the action on various grounds, including that the FCC has primary
jurisdiction over the dispute, that federal law preempts the claims asserted
against PanAmSat and Televisa, that the claims asserted against Televisa and
PanAmSat are not recognized by federal law, that the claims against PanAmSat
and Televisa fail to state a cause of action and that because the claims
against PanAmSat and Televisa depend upon the existence of enforceable rights
under the tariff Comsat filed with the FCC, the claims fail if the FCC
determines that Comsat has no such rights. In this regard, in April 1996, News
Corp. filed a complaint with the FCC challenging Comsat's tariff. Thereafter,
Comsat filed a motion with the FCC to hold that proceeding in abeyance pending
resolution of Comsat's civil suit. By letter ruling dated December 6, 1996,
the FCC denied Comsat's motion and established a schedule to resolve the
issues raised by News Corp.'s complaint. On January 27, 1997, the parties
appeared before Judge Wardlaw for a hearing on the motion to dismiss. From the
bench, the Judge denied the motions to dismiss and the parties have proceeded
to discovery. Although PanAmSat believes this action is without merit and
intends to vigorously contest this matter, it is unable to predict the final
outcome of this matter at this time.

                              BUSINESS OF GALAXY
 
OVERVIEW
 
  Galaxy is a leading provider of commercial satellite services in the United
States. Galaxy offers satellite transponder capacity to cable television
programmers, broadcast television programmers, business communications
customers and DTH service providers for video, audio and data communications
applications. Galaxy operates a fleet of ten commercial geostationary fixed
service satellites, nine of which primarily serve the United States and one of
which serves both the United States and Latin America. Galaxy also provides
satellite TT&C services for its own satellite fleet as well as for other
satellites owned by DIRECTV, PanAmSat and American Mobile Satellite
Corporation.
 
  Galaxy was established by HE in 1979 and launched its first satellite in
1983. Galaxy's expansion of service to customers in the United States was
accelerated by the acquisitions of the three-satellite Westar C-band system in
1989 and the three-satellite SBS Ku-band system in 1990. Today, in addition to
Galaxy's fleet of ten commercial satellites, Galaxy has two satellites under
construction (Galaxy VIII-i and Galaxy X) and three additional satellites in
various stages of development (Galaxy XI, Galaxy XIII-i and Galaxy XIV-i)
which are expected to provide new and replacement transponder capacity with
U.S. and international coverage. Subject to regulatory approval, Galaxy
expects to launch these five satellites by 2000. See "--Government Regulation"
and "RISK FACTORS--Regulatory Risks."
 
  Galaxy provides satellite transponder capacity to cable television
programmers such as Time Warner, Inc., Viacom, Inc., The Walt Disney Company,
Fox Basic Cable, Inc., MSNBC, Discovery Communications, Inc., and Black
Entertainment Television, broadcast television programmers such as NBC, CBS,
ABC, Warner Bros. and Group W Broadcasting, and business communications
customers such as Hughes Network Systems, General Motors, WalMart, Circuit
City, Westcott Communications, Scientific Atlanta, United Video, Microspace,
General Communications, Inc., SPACECONNECTION, BAF Satellite & Technology,
Keystone Communications and Vista Satellite Communications, Inc. In addition,
Galaxy provides satellite capacity to a subsidiary of DTVI for use by GLA, a
provider of DTH services in Latin America. GLA is a joint venture among a
subsidiary of HE and several Latin American media companies.
 
  Galaxy provides its customers with whole or partial transponder capacity
through sales contracts, sales-type lease contracts and operating lease
contracts. Galaxy has over 180 customers and, at December 31, 1996, Galaxy's
backlog of committed and likely future cash payments totaled approximately
$3,399 million. See "GALAXY MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS--Backlog."
 
BUSINESS STRATEGY
 
  Galaxy's business strategy is to provide its customers with high quality
satellite transponder capacity supported by timely and responsive technical
and customer service. Specifically, this business strategy emphasizes the
following principal elements:
 
  . Innovative Marketing;
 
  . Customer Service;
 
  . Strategic Expansion of Satellite Fleet; and
 
  . Superior Technical Characteristics and Performance.
 
 Innovative Marketing
 
  Galaxy has utilized innovative marketing programs designed to enhance the
value provided to customers by anticipating and responding to their demands
for satellite communications services. Among the marketing initiatives
utilized by Galaxy have been the (i) provision of satellite transponder
capacity on a non-common
 
                                      128
<PAGE>
 
carrier basis, (ii) marketing and sale of transponder capacity prior to
launch, (iii) creation of cable and broadcast neighborhoods, (iv) provision of
backup transponder capacity and (v) initiation of satellite-specific antenna
voucher programs for cable system operators.
 
  Prior to the launch of Galaxy I, commercial satellite transponders were
provided primarily on a common carrier basis. With the launch of Galaxy I in
1983, Galaxy began to provide transponder capacity to customers at negotiated
rates. Today, full-time customers can choose among three financing
alternatives to acquire satellite transponder capacity: a sale, a sales-type
lease or an operating lease.
 
  An important element of Galaxy's marketing strategy has been Galaxy's
practice of marketing transponder capacity on new satellites well before their
launch. For example, Galaxy has obtained substantial long-term commitments for
C-band and Ku-band capacity on Galaxy X, a hybrid satellite that is not
scheduled to be launched until 1998.
 
  Galaxy has been a pioneer in the development and marketing of cable
neighborhoods and a broadcast neighborhood. These innovations, which
concentrate a broad range of quality cable programming or broadcast
programming on certain Galaxy satellites, have made such Galaxy satellites
particularly attractive to cable programmers or broadcast programmers desiring
to widely distribute their programming to cable system operators or television
stations. Galaxy I-R, Galaxy V, Galaxy VII and Galaxy IX operate as cable
neighborhoods and Galaxy IV operates as a broadcast neighborhood.
 
  Galaxy has also been able to market its ability to provide its customers
access to backup capacity in the event of transponder or satellite failure.
Galaxy satellites have between 6 and 11 spare amplifiers per satellite to
provide backup capacity. In addition, six of the Galaxy satellites contain two
reserve transponders for every 22 primary transponders. Further, Galaxy VI
serves as an in-orbit spare satellite for Galaxy's C-band capacity.
 
  Galaxy's marketing efforts have from time to time also included antenna
voucher programs in which cable system operators are given vouchers which can
be redeemed for credit toward the purchase price of a receive antenna which
must be aimed at a specific Galaxy satellite. These programs encourage cable
programmers to utilize capacity on certain Galaxy satellites because they
increase the number of cable system operators with receive antennas aimed at
such Galaxy satellites.
 
 Customer Service
 
  Galaxy makes customer service a top priority by seeking customer input and
by responding to customer needs and requests in a timely and complete manner.
Galaxy operations personnel are available 24 hours a day to respond to
customers. In October 1996, Galaxy hosted its first annual Galaxy Users Group
conference to inform customers in the cable, broadcast, business
communications and occasional use areas of current and future Galaxy plans and
to seek customer feedback. Galaxy is also increasing communication with its
customers through direct mail, the Galaxy Website and increased account
manager visits.
 
  In order to meet its customers' operational requirements, Galaxy recently
constructed a state-of-the-art Satellite Operations Center and Network
Operations Center in Long Beach, California. Using more efficient and user-
friendly systems, the Galaxy operations personnel guide customers through the
uplink process, coordinate satellite access, monitor signal transmissions,
troubleshoot signal interference problems and advise customers regarding the
adjustment of their equipment. In addition, Galaxy's engineering personnel
work closely with Galaxy's marketing personnel to provide technical guidance
to customers during the planning and development of their service requirements
and coordinate with Network Operations Center personnel to facilitate service
initiation.
 
 Strategic Expansion of Satellite Fleet
 
  Galaxy has sought to expand its satellite fleet in order to meet the demand
of existing and potential customers. In addition to the expansion of its fleet
through the construction and launch of new satellites, Galaxy has made
strategic acquisitions of satellites and transponder capacity in order to
supplement its service offerings.
 
                                      129
<PAGE>
 
Such acquisitions have included Galaxy's acquisition in 1989 of the three-
satellite Westar fleet, which expanded Galaxy's C-band capacity and brought
Galaxy's first broadcast television customer, and Galaxy's acquisition in 1990
of the three-satellite SBS system, which provided Galaxy's first Ku-band
capacity.
 
  Galaxy's current plans for expansion of its satellite fleet both in the
United States and internationally are designed to address the growing demand
for satellite capacity by customers with a wide range of communications needs.
Anticipating the requirement for additional C-band capacity, Galaxy
established a new cable neighborhood with the launch of Galaxy IX in May 1996.
In addition, each of Galaxy X and Galaxy XI, which are expected to be launched
in 1998, is expected to provide an additional 24 C-band and 24 Ku-band
transponders to serve the United States.
 
  Galaxy's expansion plans also include the development of additional
satellites that will be designed to deliver high-power communications services
to individual consumers, as well as business and broadcasting customers
worldwide. Subject to FCC and ITU approval, two of these additional satellites
will be Galaxy XIII-i, which is expected to be launched in 1999, and Galaxy
XIV-i, which is expected to be launched in 2000. Galaxy's management is in the
process of determining the payload configuration and specifications for Galaxy
XIII-i and Galaxy XIV-i given the capabilities of the HS-702 satellite design
and anticipated customer demand.
 
 Superior Technical Characteristics and Performance
 
  The Galaxy satellite fleet consists entirely of spacecraft built by Hughes
Space and Communications ("HSC"). The newer Galaxy satellites, as well as the
Galaxy satellites under construction and development, have been or will be
designed to provide high transmission power and other technically advanced
characteristics typically sought by Galaxy's primary customers in cable,
broadcast, DTH and business communications. For example, the HS 702 satellite,
HSC's newest design, will be configurable for up to 90 high power transponders
and will contain a more efficient fuel system, thereby extending the
satellite's life expectancy. Galaxy XI, Galaxy XIII-i and Galaxy XIV-i are
expected to be HS 702 satellites.
 
  Galaxy provides support systems to control its satellites and serve its
customers. Galaxy's network of ground control and uplink stations link
Galaxy's satellites to Galaxy's Satellite Operations Center located in Long
Beach, California. Ground stations in Fillmore, California, Castle Rock,
Colorado, and Spring Creek, New York, relay orbit commands from the
controllers at the Satellite Operations Center to the orbiting satellites. The
ground stations also serve as back-up TT&C facilities and are able to track
the spacecraft during launch. In 1995, Galaxy completed installation of a new
satellite control system which enables operations personnel to interpret
satellite operations data and conduct satellite stationkeeping using efficient
user-friendly workstations. In addition, Galaxy employees at Galaxy's Network
Operations Center, located in Long Beach, California, coordinate both full-
time and occasional access to the Galaxy fleet of satellites. They also
resolve problems relating to interference with other satellite signals and
monitor satellite power levels through Galaxy's proprietary Transponder Access
and Control System.
 
SATELLITE SERVICES
 
  Galaxy offers a broad range of commercial satellite communications services,
providing transponder capacity for video distribution as well as business
communications. In addition, Galaxy provides other satellite services, such as
occasional-use transponder capacity and TT&C. In the year ended December 31,
1996, Galaxy's revenues were derived from the following services in the
following percentages:

 Video Distribution
 
  Cable Distribution. Galaxy is a leading provider of satellite transponder
capacity to cable television programmers in the United States. Cable
programmers utilize transponder capacity on Galaxy satellites primarily to
transmit their programming to cable system operators throughout the United
States for distribution on cable systems. Time Warner, Inc., Viacom, Inc., The
Walt Disney Company, Fox Basic Cable, Inc., and MSNBC are among the cable
programmers utilizing capacity on Galaxy satellites to transmit programming
such as CNN, HBO, Cinemax, Showtime, MTV, Nickelodeon, The Movie Channel, The
Disney Channel, ESPN, ESPN2, fX and MSNBC. Some of this programming is
transmitted in "multiplex" format, enabling different versions to be
transmitted for distribution in different parts of the country in order to
accommodate time zone differences or provide programming variety.
 
  Galaxy has successfully developed premium cable neighborhoods on Galaxy I-R,
Galaxy V, Galaxy VII and Galaxy IX. A cable neighborhood is formed when
popular cable programming, such as HBO, ESPN, CNN, MTV and Showtime, is
transmitted to cable system operators via particular Galaxy satellites.
Because these Galaxy satellites carry such popular programming, they attract a
base of cable system operators with receive antennas aimed at these
satellites, thereby making such satellites more attractive to other cable
programmers, including smaller niche-oriented programmers, that want cable
system operators to be able to receive their programming without having to
invest in additional receive antennas. This, in turn, enables cable system
operators to utilize only one receive antenna aimed at a particular satellite
to receive a wide variety of quality programming.
 
  Broadcast Distribution. Galaxy also provides satellite transponder capacity
to broadcast television programmers, such as NBC, CBS and ABC, who use
Galaxy's satellites for program distribution to local affiliates, satellite
newsgathering operations and "backhaul" operations (i.e., the use of a
satellite to transport a signal from a remote broadcasting site such as a
sports stadium or convention center back to network headquarters). In
addition, by providing satellite capacity on Galaxy IV to the CBS network, as
well as syndicators like Warner Bros. and Group W Video Services, Galaxy has
transformed Galaxy IV into a broadcast neighborhood through which broadcast
television programmers may distribute a variety of network and syndicated
programming to television stations with receive antennas aimed at Galaxy IV.
 
  In recent years, Galaxy has provided satellite transponder capacity to an
increasing number of niche-oriented cable and broadcast programmers. Such
niche-oriented programming focuses on a particular field of interest such as
cooking, history, sports or foreign language programming. This programming is
provided by both small programmers with only one channel and by larger
programmers desiring to expand their channel offerings. Examples of such
programmers on Galaxy satellites include Food Network, The Golf Channel, Asia
Broadcast Network, The Family Channel and The Game Show Network. Some niche
programmers provide foreign language news and entertainment programming which
is packaged by a cable system or local broadcaster with other such programming
into one channel. Niche-oriented programming has grown as cable system
operators have expanded the capacity of their systems and as individual
consumers have increasingly utilized backyard satellite dishes to watch niche-
oriented programming that may not be available locally. Niche-oriented
programming has also grown as a result of video compression, which can lower
programmers' cost per channel by increasing the number of channels that may be
transmitted on a transponder. In addition, niche-oriented programming has
become more attractive as advertisers have increasingly sought to reach
specific demographic groups.
 
  DTH Distribution. Galaxy also provides satellite transponder capacity to a
subsidiary of DTVI for use by GLA, a provider of DTH services in Latin
America. GLA, which is a joint venture among a subsidiary of HE and several
Latin American media companies, utilizes 24 high-powered Ku-band transponders
on Galaxy III-R to provide more than 140 channels of video and audio
programming to subscribers in Mexico, the Caribbean and Central and South
America. Following the successful launch of Galaxy VIII-i, this DTH service is
expected to utilize transponder capacity on Galaxy VIII-i instead of Galaxy
III-R.
 
 
                                      131
<PAGE>
 
  Subject to FCC and ITU approval, Galaxy XIII-i, Galaxy XIV-i and other future
satellites are expected to be dual payload satellites carrying high-powered Ku-
band (BSS) transponders and Ka-band transponders. See "--Government Regulation"
and "RISK FACTORS--Regulatory Risks." The Ku-band (BSS) transponders on such
satellites are expected to be well-suited for customers desiring to enter the
DTH market or expand their current DTH offerings internationally.
 
 Business Communications
 
  Galaxy provides satellite transponder capacity for business communications
(i) directly to end-users, such as General Motors, Westcott Communications,
WalMart and Circuit City and (ii) to system integrators, such as Hughes Network
Systems, Scientific Atlanta and United Video, which provide data, voice and
video communications networks to their business customers. Galaxy also provides
transponder capacity to educational institutions, such as California State
University ("CSU") and the Indiana Higher Education Telecommunication System,
for use in distance learning programs.
 
  Galaxy provides satellite transponder capacity for use in two-way VSAT
networks to both business end-users and communications carriers. Financial
transactions, point-of-sale credit and debit card purchases, manufacturing
control and inventory management, as well as ticketing and reservation
functions within the travel and lodging industry, are some of the many VSAT
applications now being served by Galaxy's transponder capacity. For example,
WalMart utilizes Galaxy's VSAT technology in its point-of-sale tracking system,
which transmits sales information via Galaxy's SBS 5 to a computer at WalMart
corporate headquarters that automatically reorders inventory.
 
  Galaxy's satellite transponder capacity also serves two types of business
television networks: (i) private networks, which link a company's headquarters
with its branches or remote sites and (ii) programming networks, which supply
educational and motivational programs to businesses within similar industries.
For example, General Motors uses Galaxy satellites to reach thousands of its
dealerships and suppliers and Westcott Communications uses Galaxy satellite
capacity to broadcast its subscription networks, which provide training in the
health and medical sciences, law enforcement, fire and emergency services,
industrial security and automotive fields.
 
  Galaxy also provides satellite transponder capacity to educational
institutions, such as CSU and the Indiana Higher Education Telecommunication
System, for use in distance learning programs. For example, CSU uses Galaxy
satellite capacity to offer distance learning programs through its CSUSAT
network. Seven campuses use the CSUSAT network, which is carried on Galaxy V,
to offer a full range of classes to more than 30 receive sites throughout
California. CSU Chico, which pioneered the use of satellite technology in the
CSU system, offers 25 upper-division courses via satellite and has served more
than 12,000 off campus students since 1980.
 
 Other Satellite Services
 
  In addition to the sale and lease of satellite transponder capacity on its
fleet of 10 commercial satellites, Galaxy provides several other satellite
services to its customers. In particular, Galaxy (i) provides TT&C services for
Galaxy satellites and several satellites owned by other companies, (ii) offers
occasional-use transponder capacity, (iii) offers backup C-band transponder
capacity on Galaxy VI and (iv) provides transponder capacity on satellites
outside of its fleet of 10 commercial satellites.
 
  TT&C Services. When a customer commits to use Galaxy transponder capacity,
the customer secures the technical support of Galaxy's Satellite Operations
Center located in Long Beach, California. Galaxy's Satellite Operations Center
provides 24-hour monitoring and control of the orbital positions and operating
conditions of Galaxy's satellites. Satellite Operations Center personnel
maintain proper orbital position and attitude, monitor on-board housekeeping
systems, adjust transponder power levels and remotely "rewire" satellites, if
necessary, to bring backup systems on-line in the event of a subsystem failure.
The necessary TT&C satellite commands
 
                                      132
<PAGE>
 
are generated by Satellite Operations Center personnel and communicated to the
satellites from Galaxy's earth stations located in Spring Creek, New York,
Castle Rock, Colorado, and Fillmore, California. In addition to providing TT&C
services for its own fleet of satellites, Galaxy has contracted to provide
TT&C services for DIRECTV's three satellites, American Mobile Satellite
Corporation's AMSC-1 and PanAmSat's PAS-2 and PAS-3 satellites.
 
  Occasional-Use Capacity. Galaxy serves occasional-use customers by offering
satellite transponder capacity through two principal methods. First, Galaxy
offers long-term transponder leases to satellite brokers, such as BAF
Communications, SPACECONNECTION and The Williams Group, who sell occasional-
use transponder capacity to their customers. These brokers resell this
capacity and specialize in "value-added services," packaging transponder
capacity with syndication distribution, fixed and transportable satellite
transmission, video conferencing and special event services for broadcast,
business, educational and government satellite users. Second, Galaxy's Video
Timesharing Services department provides occasional-use transponder capacity
directly to end-users. A computerized time availability system offers instant
scheduling information and reservations and enables customers to reserve
capacity in increments of as little as fifteen minutes.
 
  Backup Satellite Capacity. Galaxy customers may contract for C-band backup
capacity on Galaxy VI. Generally, subject to the specific terms of individual
contracts, such customers are entitled to replacement capacity on Galaxy VI if
a transponder failure occurs and no spare amplifier or reserve transponder is
available on the satellite on which they utilize capacity or if such satellite
suffers a catastrophic failure. Galaxy VI can meet a customer's immediate
needs by providing transponder capacity at Galaxy VI's current orbital
position or, subject to FCC approval, from a relocated orbital position.
Galaxy VI is able to serve as the in-orbit spare for the entire Galaxy C-band
fleet because existing customers on Galaxy VI are subject to preemption (i.e.,
removal) if the capacity utilized by such existing customers is needed to
provide backup transponder capacity to customers that have contracted for such
capacity. However, Galaxy has never had to preempt an existing full-time
customer on Galaxy VI.
 
  Other Satellite Capacity. In addition to providing transponder capacity on
its fleet of 10 commercial satellites, Galaxy provides transponder capacity on
Brasilsat A1. Galaxy has leased all of the capacity on Brasilsat Al (24 10-
watt C-band transponders) from the Brazilian company EMBRATEL until the end of
the satellite's life, which is currently expected to be 2002. Galaxy leased
this capacity to provide backup protection for Galaxy III-R, Galaxy IX and
future Galaxy satellites, and to meet the demand for occasional-use satellite
capacity. Brasilsat A1 remains licensed by the Brazilian government and Galaxy
has obtained interim authority from the FCC to use capacity on the satellite
at the 79(degrees) W.L. orbital location until December 31, 1997 in order to
provide service to the United States. Brasilsat A1 must relinquish this
orbital location when the location is ready to be occupied by the satellite
regularly assigned there by the FCC. Authorization has not yet been given to
use capacity on Brasilsat A1 at another location. This satellite operates in
inclined orbit mode and has already exceeded its design life expectancy.
Galaxy also owns and operates Leasat 5, a satellite previously used to provide
communications services to the U.S. Navy under an agreement that expired in
February 1997. Leasat 5 is currently in an inclined orbit, and Galaxy
management is exploring opportunities to lease the available capacity on
Leasat 5.
 
SATELLITE TECHNOLOGY
 
  Fixed service satellites of the type utilized by Galaxy are well-suited for
transmissions that must reach many locations over great distances
simultaneously (i.e., point-to-multipoint transmission), such as the
distribution of television programming to cable system operators, television
stations and directly to homes. Fixed service satellites are capable of
providing large geographic areas with signal coverage and, unlike terrestrial
transmission systems, the cost of satellite services does not increase with
the distance of transmission or the number of locations transmitting or
receiving signals. Fixed service satellites are also well-suited for
communications services that require access from transportable transmission
points, such as the transmission of live news coverage from an on-site truck,
because fixed service satellites can be accessed from virtually anywhere
within the geographic area they cover.
 
 
                                      133
<PAGE>
 
  Fixed service satellites typically contain transponders that transmit in one
or both of two bands of frequencies, C-band and Ku-band. C-band is a set of
relatively low frequencies (between approximately 4 GHz and 6 GHz) that
require the use of relatively large receive antennas. Cable and broadcast
distribution accounts for most of the traffic on C-band satellites. Because C-
band is shared with terrestrial point-to-point microwave stations, its use
requires coordination with other users. Ku-band is a set of relatively high
frequencies (between approximately 12 GHz and 14 GHz) which allow for the use
of smaller receive antennas. Ku-band satellites are widely used for broadcast
distribution, VSAT business communications and DTH services. Ku-band signals
operate at frequencies that are susceptible to degradation due to rain and
typically have lower availability rates than C-band signals. In addition to C-
band and Ku-band frequencies, a third band called Ka-band recently has
attracted the interest of satellite operators worldwide. Ka-band signals are
transmitted at even higher frequencies (between approximately 17 GHz and 30
GHz) than Ku-band signals and allow the use of antennas that are even smaller
than those utilized for Ku-band. However, because Ka-band signals operate at
higher frequencies, rain and other atmospheric conditions may present
challenges to effective transmission. In addition, because portions of the Ka-
band are shared with terrestrial services, the use of such frequencies
requires coordination with other users.
 
  Satellite communications service providers and their customers are
increasingly utilizing digital technology. Digital technology is the ability
to convert any form of data into the simple language of computers, expressed
in values of "1" and "0." Reducing data, whether numbers, pictures or sounds,
to those values increases the ability to manipulate and combine information.
Digital technology provides superior signal control and quality and, when
combined with compression technology, can increase the number of available
channels and reduce the cost per channel to the customer. Digital compression
levels ranging from 2:1 to 8:1, which allow the simultaneous transmission of
between two and eight channels on a single transponder, are possible for video
programming. The compression level is determined in part by the customers'
broadcast quality requirements and the type of programming being distributed,
with higher quality broadcasts and sports and other high action programming
typically having lower levels of compression due to greater data flow
requirements.
 
GALAXY SATELLITES
 
 General
 
  Galaxy's satellites can be divided into two basic categories: spin-
stabilized satellites and body-stabilized satellites. The HS 376 (Galaxy I-R,
Galaxy V, Galaxy VI, Galaxy IX, SBS 4 and SBS 5) and the HS 393 (SBS 6) are
spin-stabilized satellites, in which the solar array drums, propellant tanks
and other portions of the power and fuel systems spin at approximately 50 to
60 revolutions per minute while the antenna and communications shelf are
despun so that they remain pointed toward Earth. Spin-stabilized satellites
are less expensive and often require less time to develop and construct than
body-stabilized satellites. However, body-stabilized satellites, including the
HS 601 (Galaxy III-R, Galaxy IV and Galaxy VII), the HS 601 HP (Galaxy VIII-i,
Galaxy X and Galaxy XII) and the HS 702 (Galaxy XI, Galaxy XIII-i and Galaxy
XIV-i), which contain large deployable solar array wings, are designed to
offer greater power and larger payloads. For example, the HS 702 satellite
will offer customers nearly twice the capacity and power of most commercial
satellites now in operation. In addition, Galaxy's HS 702 satellites and at
least one of Galaxy's HS 601 HP satellites (Galaxy VIII-i) are expected to
offer XIPS which, by utilizing fuel more efficiently, will extend the
satellites' life expectancies.

- --------
 (1) The expected end of useful life for each of Galaxy's operational
     satellites (other than SBS 4) is based on a fuel level estimate at
     December 31, 1996. The expected end of useful life for SBS 4 is based on
     the degree of its north-south inclination at December 31, 1996.
 (2) Satellite transponders receive transmissions from Earth and relay them
     back to Earth. Transponders are composed of receivers, preamplifiers,
     power amplifiers, frequency shifters and a host of other electronics.
 (3) Ku-band is a range of relatively high frequencies (between approximately
     12 GHz and 14 GHz) used for commercial satellite communications. Ku-band
     is widely used for distribution of broadcast television and DTH services,
     as well as business communications, and allows for the use of relatively
     small receive antennas.
 (4) C-band is a range of relatively low frequencies (between approximately 4
     GHz and 6 GHz) used for commercial satellite communications. C-band is
     used primarily for cable and broadcast distribution and requires the use
     of relatively large receive antennas on the ground.
 (5) Bandwidth is one measure of the information carrying capacity of a
     transponder. A transponder's bandwidth and power together determine the
     amount of information that can be carried.
 (6) Output power is the transmitter power of each transponder and is not a
     measure of the signal power received on Earth. High output power allows
     for the use of smaller and less expensive receive antennas to obtain a
     satellite signal.
 (7) Satellite operators may opt to extend the life of a satellite by allowing
     it to move into a fuel-conserving mode called "inclined orbit." When a
     satellite is put into inclined orbit, only east-west station-keeping is
     continued. While in this mode, the satellite moves in a figure-8 crossing
     the equator twice daily. The uncorrected north-south inclination
     increases over time and certain customers must retrofit their existing
     ground equipment or purchase new equipment to enable them to track the
     movement of the satellite. After reaching a certain degree of north-south
     inclination, tracking antennas can no longer reliably follow the movement
     of the satellite and its useful life ends.

- --------
(1) The expected end of useful life for each of Galaxy's expected future
    satellites is based on the terms (with respect to Galaxy VIII-i and Galaxy
    X) or anticipated terms (with respect to Galaxy XI, Galaxy XIII-i and
    Galaxy XIV-i) of the relevant satellite construction contract and the
    terms (with respect to Galaxy VIII-i, Galaxy X and Galaxy XI) or
    anticipated terms (with respect to Galaxy XIII-i and Galaxy XIV-i) of the
    relevant satellite launch arrangement.
(2) Satellite transponders receive transmissions from Earth and relay them
    back to Earth. Transponders are composed of receivers, preamplifiers,
    power amplifiers, frequency shifters and a host of other electronics.
(3) Ku-band is a range of relatively high frequencies (between approximately
    12 GHz and 14 GHz) used for commercial satellite communications. Ku-band
    is widely used for distribution of broadcast television and DTH services,
    as well as business communications, and allows for the use of relatively
    small receive antennas.
(4) C-band is a range of relatively low frequencies (between approximately 4
    GHz and 6 GHz) used for commercial satellite communications. C-band is
    used primarily for cable and broadcast distribution and requires the use
    of relatively large receive antennas on the ground.
(5) Bandwidth is one measure of the information carrying capacity of a
    transponder. A transponder's bandwidth and power together determine the
    amount of information that can be carried.
(6) Output power is the transmitter power of each transponder and is not a
    measure of the signal power received on Earth. High output power allows
    for the use of smaller and less expensive receive antennas to obtain a
    satellite signal.
 
                                 GALAXY VIII-I
 
  Subject to FCC approval of Galaxy's pending application for Galaxy VIII-i,
this satellite, which is scheduled to be launched in 1997, will be co-located
with Galaxy III-R and is to replace Galaxy III-R as the satellite by which GLA
delivers DTH programming to Mexico, Central and South America and the
Caribbean. Subject to FCC approval, Galaxy VIII-i is expected to have 32 115-
watt Ku-band transponders. Galaxy VIII-i will be one of the first HS 601HP
satellites to be launched carrying XIPS, a new technology designed to reduce a
satellite's fuel requirements and lengthen its in-orbit life. This satellite
will have a life expectancy of 15 years.

                                   GALAXY X
 
  Galaxy X, which the FCC recently authorized Galaxy to construct, launch and
operate, will be an HS 601 HP hybrid satellite carrying 24 20-watt C-band
transponders and 24 63-watt Ku-band transponders. Galaxy X is currently under
construction and scheduled for launch in the spring of 1998 to 123(degrees)
W.L. This satellite will have a life expectancy of 12 years. Galaxy IX and SBS
5 are currently located at 123(degrees) W.L. and will be moved after the
successful launch of Galaxy X. Galaxy IX will move to its FCC assigned
position at 127(degrees) W.L. and SBS 5 will either be sold or be moved to
another yet-to-be determined location. Galaxy IX C-band customers migrating to
Galaxy X after its launch will include Viacom, with the west coast feeds of
Showtime, Nickelodeon, The Movie Channel and MTV, and the national feed of The
Sundance Channel. Galaxy X will serve the continental United States, Alaska,
Hawaii and the Caribbean basin. Galaxy X already has a number of customers
contracted to use its Ku-band transponders full-time, including General
Communications, Inc., Computer Television Network and Televideocomm.
 
                                   GALAXY XI
 
  Galaxy plans to file with the FCC for authority for Galaxy XI, which is
expected to be the first HS 702 satellite, as a replacement satellite for
Galaxy VI (C-band) and SBS 6 (Ku-band), co-located at 74(degrees) W.L. Subject
to FCC approval, it is expected that Galaxy XI will be launched to such
orbital location in the summer of 1998 and will have a life expectancy of 15
years. Galaxy XI is expected to carry a dual payload of 24 20-watt C-band
transponders and 24 75-watt Ku-band transponders.
 
                                  GALAXY XII
 
  Galaxy's management intends to contract with HSC for the procurement of
long-lead items for Galaxy XII, which will act as a ground spare providing
backup for the launch of Galaxy X and Galaxy XI and which may be used as an
additional satellite if not deployed as a spare. Galaxy XII is expected to be
an HS 601 HP satellite with a life expectancy of 15 years. As currently
contemplated, the satellite will be built by HSC and will have 24 Ku-band
transponders and 24 C-band transponders. The management of Galaxy has not yet
determined the precise orbital location, region covered or configuration for
Galaxy XII. Accordingly, Galaxy has not yet filed an application with the FCC
for authority to launch or operate Galaxy XII.
 
                                 GALAXY XIII-I
 
  Subject to FCC approval of Galaxy's pending application for Galaxy XIII-i,
this HS 702 satellite is expected to provide international coverage. Galaxy
XIII-i is expected to be launched in 1999 and is designed to have a life
expectancy of 15 years. Galaxy's management is in the process of determining
the payload configuration and specifications for Galaxy XIII-i given the
capabilities of the HS-702 satellite design and anticipated customer demand.
The orbital location for Galaxy XIII-i also remains to be determined.
 
                                 GALAXY XIV-I
 
  Subject to FCC approval of Galaxy's pending application for Galaxy XIV-i,
this HS 702 satellite also is expected to provide international coverage.
Galaxy XIV-i is expected to be launched in 2000 and is designed to have a life
expectancy of 15 years. Galaxy's management is in the process of determining
the payload configuration and specifications for Galaxy XIV-i given the
capabilities of the HS-702 satellite design and anticipated customer demand.
The orbital location for Galaxy XIV-i also remains to be determined.
 
 Additional Future Satellites
 
  Galaxy also has applied to the FCC for authorization to construct, launch
and operate an international hybrid Ku-band and extended Ku-band satellite to
be located at 91(degrees) W.L. and has applications pending to construct,
launch and operate additional hybrid Ka-band and Ku-band (BSS) satellites that
are expected, subject to FCC and ITU approval, to provide international
coverage. See "--Government Regulation" and "RISK FACTORS--Regulatory Risks."
In addition, Galaxy's business plan contemplates the filing of additional
applications for authorization to launch and operate satellites that will
provide U.S. and/or international service.

SATELLITE DEVELOPMENT AND CONSTRUCTION
 
  Galaxy currently has two satellites under construction (Galaxy VIII-i and
Galaxy X) and three satellites in various stages of development (Galaxy XI,
Galaxy XIII-i and Galaxy XIV-i). Galaxy has entered into agreements with HSC
for the construction and testing of Galaxy VIII-i and Galaxy X, both HS 601 HP
satellites, to be delivered in the fall of 1997. The agreement contains a
limited pre-launch warranty that Galaxy VIII-i will be free from any defects
in material or workmanship and will conform to all applicable specifications
and drawings. This warranty is limited to correction or replacement of the
defective item or system. Title and risk of loss will transfer to Galaxy upon
the earlier of (i) the completion of in-orbit testing by HSC, (ii) 45 days
after intentional ignition of any rocket motor on the launch vehicle or (iii)
upon partial failure, total failure or total constructive failure of the
satellite as defined in the applicable launch insurance contract. The
agreements provide that if the delivery is delayed due to the fault of Galaxy,
Galaxy will be obligated to pay HSC its reasonable costs incurred as a result
of the delay plus a profit component. The Galaxy X agreement also provides for
certain contract price reduction in the event of a delay due primarily to
HSC's fault.
 
  Galaxy has also entered into letter agreements with HSC authorizing HSC to
take certain limited actions in connection with the development of Galaxy XI,
Galaxy XIII-i and Galaxy XIV-i. Prior to the Closing Date, Galaxy expects to
enter into agreements with HSC for the construction and testing of Galaxy XI,
Galaxy XIII-i and Galaxy XIV-i and for the procurement of long-lead items for
Galaxy XII.
 
LAUNCH ARRANGEMENTS
 
  Galaxy has entered into an agreement (the "Launch Agreement") with Hughes
Space & Communications International, Inc. ("HSCI"), whereby HSCI has agreed
to provide certain launch services to Galaxy, such services to be provided by
third-party launch providers under contract with HSCI. Subject to FCC
approval, Galaxy intends to launch Galaxy VIII-i in the fall of 1997 from the
Cape Canaveral Air Station in Florida on a Lockheed Martin ("Lockheed") Atlas
IIA.S. launch vehicle. The Atlas IIA.S. is Lockheed Martin's latest generation
of launch vehicle and provides increased performance and payload capacity. The
successful launch rate for the Atlas II, Atlas IIA and Atlas IIA.S. launch
vehicles has been 100%, with a successful launch rate of approximately 87.1%
for all Atlas launch vehicles.
 
  Galaxy plans to launch Galaxy X in the spring of 1998 from the Cape
Canaveral Air Station in Florida on an MDC Delta III launch vehicle. This
launch will be the first commercial launch utilizing the Delta III, MDC's
latest generation of launch vehicle, a high-performance launch vehicle capable
of carrying larger payloads. The Delta II, MDC's previous generation launch
vehicle, upon which the Delta III technology is based in part, has had a
successful launch rate of approximately 97%. On January 17, 1997, a Delta II
launch vehicle carrying a United States Air Force satellite suffered a launch
failure. MDC has suspended its Delta II launch schedule pending its
investigation into the failure, and, pending completion of such investigation,
has notified HSCI that there may be delays requiring an extension of the Delta
III launch schedule.
 
  Subject to FCC approval, Galaxy plans to launch Galaxy XI in the summer of
1998 via a Sea Launch Zenit launch vehicle. Sea Launch is a joint venture
between Boeing Commercial Space Co. (United States), Kavaerner A.S. (Norway),
RSC-Energia (Russia) and the NPO-Yuzhnoye space concern (Ukraine). This launch
will be the first commercial launch via the Sea Launch service, which will
utilize a three-stage launch vehicle launched from a novel 430-foot-long semi-
submersible launch platform in the Pacific Ocean near the equator. The NPO-
Yuzhnoye space concern will provide the first two stages of the launch
vehicle, based upon prior generation Zenit launch vehicles, and RSC-Energia
will provide the third stage of the launch vehicle, based upon the fourth
stage of prior generation Proton launch vehicles. Prior generation Zenit
launch vehicles have been utilized for several Russian government satellite
launches with a success rate of approximately 89%, and the fourth stage of
prior generation Proton launch vehicles has a launch success rate of
approximately 95%. The Sea Launch service is designed to efficiently launch a
large satellite payload into an orbit that is closer to the desired orbit,
thereby saving satellite fuel and extending satellite life.
 
                                      142
<PAGE>
 
  Under the terms of the Launch Agreement, Galaxy may terminate each of the
above-mentioned Lockheed, MDC and Sea Launch launches at its option, subject
to the payment of a specified termination fee which increases as the
applicable launch date approaches. In addition, Galaxy may terminate each of
such launches without penalty if the applicable launch provider causes a delay
that is longer than a specified period. The Launch Agreement also provides
that Galaxy may postpone each of such launches for a specified period before
the applicable launch provider is entitled to terminate its launch. In
addition, in the event of a failure of any of such
launches Galaxy may exercise the right to obtain a replacement or new launch
within a specified period following its request for relaunch.
 
  Galaxy expects to enter into agreements to secure launches for additional
future satellites as necessary. There can be no assurance, however, that
Galaxy will be able to obtain necessary future launches. Additionally, a
significant delay in the launch of any of Galaxy's satellites could enable
customers who have pre-purchased or agreed to lease capacity on such
satellites to terminate their contracts. See "RISK FACTORS--Risk of Delays,
Excess Weight."
 
INSURANCE
 
  Galaxy historically has purchased satellite launch insurance in an amount
sufficient to cover the in-orbit replacement cost of its satellites, including
construction, launch and launch insurance costs. Galaxy typically purchases
launch insurance approximately three months prior to the applicable launch.
Launch insurance policies generally cover both total loss and partial loss and
contain terms similar to the terms described below with respect to in-orbit
insurance.
 
  Typically, in-orbit insurance coverage commences after a satellite has been
satisfactorily tested in-orbit. Galaxy maintains in-orbit insurance for each
of its operational satellites. At December 31, 1996, Galaxy carried
approximately $117.2 million of in-orbit insurance for Galaxy I-R, $222
million of in-orbit insurance for Galaxy III-R, $201.1 million of in-orbit
insurance for Galaxy IV, $68.8 million of in-orbit insurance for Galaxy V,
$58.9 million of in-orbit insurance for Galaxy VI, $256.6 million of in-orbit
insurance for Galaxy VII, $113 million of in-orbit insurance for Galaxy IX,
$15.6 million of in-orbit insurance for SBS 4, $28.9 million of in-orbit
insurance for SBS 5 and $103.9 million of in-orbit insurance for SBS 6. The
amount of in-orbit insurance for a given satellite is calculated as follows:
transponders sold are initially insured at the base sales price of the
transponder; transponders leased under a sales-type lease are initially
insured for the net present value of lease payments; transponders leased under
operating leases are initially insured for the net book value of the
transponder; and the amount of in-orbit insurance coverage for each satellite
declines on a straight line or variable rate basis over the coverage period,
except for Galaxy IX and Galaxy III-R with respect to which the amount of
insurance is currently fixed. Under Galaxy's in-orbit insurance policies, if a
total satellite failure occurs (meaning the satellite is completely unusable
or has an actual remaining satellite capacity of 50% or less of predicted
remaining satellite capacity) then the loss payee is entitled to the
applicable amount of insurance. If there is a partial satellite failure
(meaning the actual remaining satellite capacity is reduced to less than or
equal to 90% (with respect to Galaxy III-R, Galaxy IV and Galaxy VII) or 100%
(with respect to Galaxy I-R, Galaxy V, Galaxy VI, Galaxy IX, SBS 4, SBS 5 and
SBS 6), but more than 50% of the predicted remaining satellite capacity), then
the loss payee is entitled to receive the applicable amount of insurance
multiplied by the percentage decrease in satellite capacity. With respect to
Galaxy VII, Galaxy IV and Galaxy III-R only, if there is a total payload
failure with respect to the C-band payload (meaning that there are fewer than
13 operating C-band transponders in the payload) then the loss payee is
entitled to receive 40% of the applicable amount of insurance, and if there is
a total payload failure with respect to the Ku-band payload (meaning that
there are fewer than 13 operating Ku-band transponders in the payload), then
the loss payee is entitled to receive 60% of the applicable amount of
insurance. Galaxy typically obtains in-orbit insurance policies with two-year
coverage periods and historically has renegotiated its policies in October of
each year. Galaxy concluded its renegotiations for the in-orbit insurance
policy for Galaxy I-R, Galaxy V, Galaxy VI, Galaxy IX, SBS 4, SBS 5 and SBS 6
on October 30, 1996, with an effective date for the new policy of October 12,
1996. Galaxy recently concluded negotiations with respect to the in-orbit
insurance for Galaxy VIII-i for the two year period following its launch.
Galaxy will be renegotiating its in-orbit insurance policy for Galaxy III-R,
Galaxy IV and Galaxy VII in the first quarter of 1997, based on new estimates
of satellite life predictions to be made available in late April.

  Galaxy's in-orbit and launch insurance policies typically include customary
commercial satellite insurance exclusions including damage or loss caused by
(i) war or warlike action in time of peace or war, (ii) any anti-satellite
device, or device employing atomic or nuclear fission and/or fusion or device
employing laser or directed energy beams, (iii) insurrection, strikes, riot,
civil commotion, rebellion, revolution, civil war, usurpation or action taken
by a government authority in hindering, combating or defending against such an
occurrence, whether there be declaration of war or not, (iv) confiscation by
order of any government or governmental authority or agent (whether secret or
otherwise) or public authority, (v) nuclear reaction, nuclear radiation or
radioactive contamination of any nature, whether such loss or damage be direct
or indirect, except for radiation naturally occurring in the space
environment, (vi) electromagnetic or radio frequency interference, except for
physical damage to a satellite directly resulting from such interference,
(vii) willful or intentional acts of Galaxy designed to cause loss or failure
of a satellite, (viii) third-party liability and (ix) loss of revenue, extra
expenses, incidental damages and/or consequential damages.
 
SALE-LEASEBACK ARRANGEMENTS
 
  Galaxy entered into several sale-leaseback arrangements with respect to
certain transponders on SBS 6, Galaxy VII and Galaxy III-R in December 1991,
September 1993 and February 1996, respectively. All of the other operational
Galaxy satellites are owned by Galaxy and it is expected that all of Galaxy's
planned future satellites will be owned by Galaxy. Pursuant to the agreements
governing such arrangements, Galaxy sold 19 Ku-band transponders on SBS 6 for
approximately $204.7 million, 16 Ku-band and 14 C-band transponders on Galaxy
VII for approximately $314.8 million and 24 Ku-band transponders on Galaxy
III-R for $252.0 million. Concurrently with such sale, Galaxy agreed to lease
back the same transponders on terms that require Galaxy to make scheduled rent
payments and operate and maintain such transponders and the applicable
satellites for terms of 11.2 years, 11 years and 6.9 years, respectively (the
"Leases"). During the initial term of each Lease, Galaxy is obligated to make
semi-annual rent payments in an amount at least equal to the payments of
interest and principal due on indebtedness that was incurred by the third
party that purchased the transponders subject to such Lease (the
"Indebtedness") and to enable such third party to recoup a significant part of
its investment in such transponders. Such Indebtedness is secured by the
related Lease and the transponders covered thereby.
 
  Galaxy's payment obligations under each sale-leaseback arrangement are
guarantied by HE pursuant to related guaranty agreements. Although the
Assurance Agreement provides that HE will continue to guaranty such
arrangements after the Closing Date, the Reorganization Agreement requires New
PanAmSat to enter into an agreement with HE to pay and indemnify HE for
performing any of its obligations under such guaranties.
 
  At the end of the initial term of each Lease, Galaxy has the option of
renewing such Lease through the end of the useful life of the applicable
satellite. Renewed leases generally will be subject to the same terms and
conditions of the Lease that was renewed, except that the rent amount will be
the fair market rental value of the applicable transponders at the time of
such renewal. Galaxy also has the right to terminate any Lease if Galaxy
determines in good faith that the continued lease of the transponders subject
to the Lease has become uneconomical or that the transponders subject to such
Lease have become obsolete or surplus to Galaxy's needs. Upon any such
termination, however, Galaxy is required to assist in reselling such
transponders to another party and Galaxy will be responsible for making up any
shortfall between the proceeds received in such sale and a specified
termination amount. Finally, Galaxy has the option under each Lease to
exercise an Early Buy Out Option. Under the Leases for SBS 6, Galaxy can
exercise an Early Buy Out Option on 8 of SBS 6's transponders on June 26,
1998, or December 26, 1999, for $57.6 million or $46.2 million, respectively,
and can exercise an Early Buy Out Option on SBS 6's remaining 11 transponders
on January 3, 1998, or January 3, 2000, for $94.1 million or $65.3 million,
respectively. Galaxy can exercise Early Buy Out Options for 22 of the
transponders on Galaxy VII on January 2, 1999, for $138.6 million, and can
exercise Early Buy Out Options with respect to the 8 remaining leased
transponders on such satellite on July 2, 1999, for $57.3 million. With
respect to the leased transponders on Galaxy III-R, Galaxy has an Early Buy
Out Option on July 2, 1999, for $170.4 million. Payment of the Early Buy Out
Option prices may be partially satisfied by Galaxy's assumption of the
underlying leveraged lease debt. If Galaxy elects to exercise any Early Buy
Out Option, the respective Early Buy Out Option payments would be reduced to
the extent of the principal amount of such debt that is assumed.
 
                                      144
<PAGE>
 
  Galaxy also is required under each of the Leases to obtain and maintain in-
orbit insurance on the satellite subject to such Lease and, upon the loss of
one or more transponders, to either pay a specified loss amount or provide
replacement transponder capacity to the lessor under such Lease. Galaxy has
certain additional payment obligations under each Lease in the event that
Galaxy fails to make lease payments or perform its other obligations under
such Lease or if HE fails to adhere to the terms of its guaranty of such
Lease. Finally, each of the Leases imposes limits on the ability to move the
satellite on which transponders are located other than in certain specified
situations and imposes limitations on the ability of Galaxy to consolidate or
merge with another entity unless certain circumstances are satisfied.
 
COMPETITION
 
  The communications services market is highly competitive. Galaxy competes
with several companies and other entities which own or utilize satellite
and/or terrestrial transmission facilities. Most or all of such competitors
have substantial resources and a few of such competitors have equal or greater
resources than Galaxy.
 
 Other Satellite Operators
 
  Galaxy faces significant competition in the provision of satellite services
to the United States. Galaxy, GE Americom, Loral SpaceCom and Comsat all
currently provide fixed satellite services to the United States. Loral
SpaceCom has received authorization from the FCC and, subject to meeting
certain financial requirements, Orion and Echostar Communications Corporation
have received authorization from the FCC to construct, launch and operate
fixed service satellites with U.S. coverage. Also, Loral SpaceCom recently
acquired AT&T's Skynet Satellite Services business. In addition, the FCC has a
pending rulemaking proceeding that proposes to codify the terms under which
foreign-licensed satellite systems, of which there are many, may serve the
United States, and certain foreign-licensed satellites have coverage areas
that include the United States. Increased competition may also result from a
World Trade Organization agreement pursuant to which the United States has
committed to opening its telecommunications market, including its satellite
services markets with the exception of DTH and direct broadcast satellite
services, to foreign-owned and foreign-licensed competitors from World Trade
Organization countries. With respect to the operation of the Ku-band payload
of Galaxy III-R, Galaxy also faces significant competition in Latin America,
and Galaxy may, in the future, face significant competition in other
international markets in which it may operate.
 
 Terrestrial Communications Service Providers
 
  Galaxy faces competition from terrestrial communications service providers,
such as facilities-based long distance telephone companies, resellers of long-
distance telephone capacity, local exchange carriers, cable companies and
wireless cable companies. Such companies utilize various means of
transmission, including copper wire, coaxial cable, fiber-optic cable and
microwave-based facilities. Galaxy believes, however, that with respect to
certain areas of its business, which primarily involve point-to-multipoint
communications over great distances, satellite technology is often more
efficient and less expensive than terrestrial technologies. There can be no
assurance, however, that technological, regulatory or other developments will
not hinder Galaxy's ability to compete or enhance terrestrial communications
service providers' ability to compete in Galaxy's primary areas of business.
 
GOVERNMENT REGULATION
 
  The satellite industry is highly regulated both in the United States and
internationally. The ownership and operation of Galaxy's fixed service
satellite system is subject to the rules and regulations of the FCC, which
acts pursuant to the Communications Act and related federal laws. The FCC
regulates, among other things, the construction, launch and operation of U.S.
satellites, and violations of the FCC's rules can result in various sanctions,
including fines, loss of authorizations or the denial of applications for new
authorizations or for renewals of existing authorizations. Galaxy also is
subject to regulation by the national communications authorities of any
foreign countries in which it may operate. In addition, Galaxy is subject to
the Intelsat
 
                                      145
<PAGE>
 
consultation process and the ITU frequency coordination process, which can
result in the imposition of various restrictions on Galaxy's business that may
have a material adverse effect on its operations.
 
  The following is a brief summary of relevant provisions of certain U.S. and
international laws and regulations that are applicable to Galaxy's operations.
 
 FCC Regulation of U.S. Satellites
 
  The FCC is the governmental body with primary authority in the United States
over satellite operators. Among other things, the FCC allocates portions of
the radio frequency spectrum to certain services and grants licenses to and
regulates individual entities using that spectrum. Various legislative and
regulatory proposals under consideration from time to time by Congress, the
FCC and various other federal agencies have in the past materially affected,
and may in the future materially affect, Galaxy and the satellite industry. In
addition, certain aspects of existing federal laws and regulations are the
subject of legislative or administrative proposals to modify, repeal or adopt
new laws and administrative regulations and policies.
 
 Elimination of Regulatory Distinctions Between Domestic and International
Systems
 
  Prior to recent changes to its regulations, the FCC distinguished between
domestic U.S. satellites and "separate international systems," i.e., U.S.-
licensed satellites that provided international service. Specifically, with
certain exceptions for the provision of trans-border services and operators
that obtained separate FCC authorizations, U.S. domestic satellite licensees
were permitted to serve only the United States. Similarly, except for the
provision of U.S. service that was ancillary to international service and
except for operators that obtained separate FCC authorizations, separate
system satellite licensees were permitted to provide only international
service. On January 22, 1996, the FCC released its Domestic and International
Satellite Consolidation Order ("DISCO I") eliminating the previous regulatory
distinctions, and the FCC now regulates all U.S.-licensed geostationary fixed
service satellites under a unified regulatory scheme in which they can provide
a full range of domestic and international services. In practice, however,
existing U.S. domestic satellites are designed to serve principally the United
States. Petitions for reconsideration of the order establishing the new
policies, including a petition filed by PanAmSat, are pending before the FCC.
There can be no assurance that further modifications to the FCC's rules and
policies will not be made as a result of those petitions for reconsideration,
or that any such modifications will not have a material adverse effect on
Galaxy's operations.
 
 Licensing Terms
 
  License Period. The FCC grants authorizations to satellite operators, such
as Galaxy, that meet the FCC's legal, technical and financial qualification
requirements. Such authorizations are for 10-year terms, although the FCC
reserves the right to grant or renew satellite licenses for periods of less
than 10 years if, in its judgment, the public interest, convenience and
necessity will be served by such action. Certain Galaxy satellites are, or are
expected to be, operational beyond their 10-year license terms. The
authorization for the SBS 4 satellite held by Galaxy expired in 1994, and
Galaxy has obtained successive 180-day grants of special temporary
authorization from the FCC to enable it to continue to operate the satellite
past the expiration of the satellite's license. There can be no assurance,
however, that the FCC will continue to grant such special temporary
authorizations or other extensions or renewals of license terms with respect
to the SBS 4 satellite or other satellites. A denial of such authority could
have a material adverse effect on Galaxy's operations.
 
  To conserve fuel and further extend the life of SBS 4, Galaxy currently is
operating the satellite in "inclined orbit mode" pursuant to FCC
authorization. Brasilsat A1 also is operating in inclined orbit mode. In
inclined orbit, a satellite no longer operates within normal north-south
stationkeeping parameters. The FCC requires that, if it assigns another
satellite operating within normal stationkeeping parameters to an orbital
location in use by an inclined orbit satellite, the inclined orbit satellite
must be relocated or deorbited once the new satellite is ready to occupy that
location. The FCC recently assigned satellites to 77(degrees) W.L. and
79(degrees) W.L., the orbital locations currently used by SBS 4 and Brasilsat
A1. Once the newly assigned satellites are ready to occupy those locations,
 
                                      146
<PAGE>
 
Galaxy must relocate SBS 4 and cause the Brazilian government, which operates
Brasilsat A1, to relocate that satellite as well. There can be no assurance
that those satellites will be authorized to provide service at any other
desirable orbital locations.
 
  Non-Common Carrier Operation. The FCC's authorizations permit Galaxy to
operate its satellites on a non-common carrier basis. As a non-common carrier,
Galaxy is free to set prices and serve customers according to its business
judgment, without rate of return or price cap regulation or the obligation not
to discriminate among customers, and with minimal governmental scrutiny of its
business decisions. In addition to the licensing of individual satellites and
earth stations, Galaxy is subject to the FCC's review primarily to ensure the
avoidance of interference with other users of the radio frequency spectrum and
compliance with various FCC rules of general application to satellite
operators. The FCC reserves the right to require a satellite to be relocated
to a different orbital location if the FCC determines that it is in the public
interest that such a change be made, but the FCC rarely has used this
authority.
 
 Authorizations To Construct, Launch and Operate Satellites
 
  Authorizations. Galaxy has obtained FCC authorization to construct, launch
and operate, and it currently is operating: the C-band Galaxy I-R at
133(degrees) W.L.; the hybrid (C-band and Ku-band) Galaxy III-R at 95(degrees)
W.L.; the hybrid (C-band and Ku-band) Galaxy IV at 99(degrees) W.L.; the C-
band Galaxy V at 125(degrees) W.L.; the C-band Galaxy VI at 74(degrees) W.L.;
the hybrid (C-band and Ku-band) Galaxy VII at 91(degrees) W.L.; the C-band
Galaxy IX at 123(degrees) W.L. (to be relocated to 127(degrees) W.L. upon the
launch of Galaxy X into the 123(degrees) W.L. orbital location); the Ku-band
SBS 4 at 77(degrees) W.L.; the Ku-band SBS 5 at 123(degrees) W.L.; and the Ku-
band SBS 6 at 74(degrees) W.L. In its May 7, 1996 Orbital Assignment Order and
in a subsequent order released on November 21, 1996, the FCC authorized Galaxy
to construct, launch and operate the hybrid (C-band and Ku-band) Galaxy X
satellite, and assigned that satellite to the 123(degrees) W.L. orbital
location. The FCC also has granted Galaxy special temporary authorization to
utilize the transponder capacity of the Brazilian-owned and licensed C-band
Brasilsat A1 satellite from the 79(degrees) W.L. location in order to provide
U.S. service. Galaxy has applied for the proposed extended Ku-band Galaxy
VIII-i satellite, upon the successful launch of which into the 95(degrees)
W.L. orbital location the Ku-band payload of Galaxy III-R will be returned to
U.S. service. Galaxy also has applied for a hybrid (Ku- and extended Ku-band)
international satellite to be located at 91(degrees) W.L. In addition, Galaxy
has an application pending for authorization for several hybrid Ka-band and
Ku-band (BSS) international geostationary satellites, including Galaxy XIII-i
and Galaxy XIV-i. In response to such application, the FCC has assigned to
Galaxy 12 Ka-band orbital locations that are suitable for international
satellite service, six of which will be retained by Galaxy after the
Reorganization and six of which will be retained by HE for use in a separate
business, subject to certain non-compete restrictions contained in the
Stockholders Agreement. In addition, an application remains pending for an
additional Ka-band location that Galaxy expects to utilize. Galaxy's
applications with the FCC for Ku-band (BSS) satellites at 12 orbital locations
are also pending before the FCC. Use of the orbital positions for Ku-band
(BSS) satellites is currently being coordinated through the ITU and is subject
to approval by the ITU as a modification to its current BSS plan. See "--
International Telecommunications Union Coordination." Galaxy plans to file an
application for authorization for the hybrid (C-band and Ku-band) Galaxy XI as
a replacement satellite at 74(degrees) W.L. In addition, Galaxy's business
plan contemplates the filing of additional applications for authorization for
satellites that will provide U.S. and/or international service.
 
  Application Processing. In processing applications for authorization for
new, or "expansion," satellites that will provide primarily domestic U.S.
service, the FCC traditionally has granted such authorizations through
consolidated "processing rounds" in which it considers and resolves
contemporaneously filed applications. Prior to the FCC's DISCO I decision,
this process had been limited to domestic satellite applications. The FCC's
decision extended the processing round procedure to future applications for
all U.S.-licensed satellites regardless of the proposed coverage area. The
most recent processing round for domestic U.S. C-band and Ku-band fixed
service satellites began in December 1994 and recently was completed following
the issuance of the FCC's Orbital Assignment Order in May 1996 and individual
orders in November 1996 assigning orbital locations and granting
authorizations to construct, launch and operate satellites to applicants for
proposed expansion and replacement satellites, including Galaxy IX and Galaxy
X. A petition for reconsideration of certain orbital
 
                                      147
<PAGE>
 
assignments (other than assignments granted to Galaxy) made in the processing
round presently is pending before the FCC. Applications for replacement
satellites typically are resolved outside of a processing round.
 
  The FCC's rules limit the number of new satellite authorizations that
operators may be granted at one time. The rules provide that legally,
technically and financially qualified applicants not already holding satellite
authorizations initially may be assigned up to two orbital locations in each
pair of frequency bands proposed. For existing operators, the FCC's rules
specify that legally, technically and financially qualified applicants may be
assigned no more than one additional orbital location beyond their current
authorizations in each frequency band in which they are authorized to operate,
provided that their in-orbit satellites are essentially filled and that they
have no more than two unused orbital locations for previously authorized but
unlaunched satellites in that band. The FCC historically has interpreted the
rules to allow applicants to be authorized for more than those one or two
satellites at a time in a given frequency band when those additional
satellites are needed to serve geographically separate areas, but there can be
no assurance that the FCC will maintain this interpretation in the future.
These rules impose limitations on the pace at which Galaxy may be able to add
future satellites to its fleet.
 
  On December 16, 1996, the FCC released an order streamlining its rules and
regulations governing satellite applications and licensing procedures. The new
rules are expected to take effect in April 1997. Under the new rules, the FCC
has, among other things, abolished the construction permit requirement for
satellites in favor of a requirement that operators submit prior written
notification that they plan to commence satellite construction at their own
risk. The FCC also has eliminated the requirement to obtain FCC authorization
prior to placing a satellite into inclined orbit and relaxed rules governing
satellite licensee reports. Thus, under the FCC's new policy, satellite
operators such as Galaxy will be able to construct future satellites, at their
own risk, without prior FCC approval.
 
  Pending Proceedings. On May 14, 1996, the FCC released a notice of proposed
rulemaking to require that U.S.-licensed earth stations that seek to
communicate with foreign-licensed satellites demonstrate that the foreign-
licensed satellite's markets provide U.S. licensees effective competitive
opportunities to provide an equivalent service there. To the extent that the
FCC's proposal, whether or not it is adopted, is viewed unfavorably by foreign
regulators, it could complicate Galaxy's efforts to obtain those
authorizations that may be necessary to provide international service to
foreign nations.
 
 Foreign Telecommunications Authorities
 
  With respect to the provision of international satellite service, Galaxy may
be subject to the communications and/or broadcasting laws and regulations of
foreign telecommunications authorities. While these laws and regulations vary
from country to country, foreign telecommunications authorities generally have
not required companies to obtain licenses or regulatory authorizations in
order to provide space segment capacity to licensed entities within those
countries; however, foreign telecommunications authorities in certain
countries may require that foreign-licensed satellite operators obtain
authorizations in order to provide satellite services in such countries. Laws
and regulatory practices governing access to satellite systems vary
substantially among countries. Certain countries have liberalized their
national communications market, allowing multiple entities to seek licenses to
provide voice, data or video services for their own use or for third-party
use, to own and operate private earth station equipment, and to choose a
provider of satellite capacity. Some countries allow licensed radio and
television broadcasters and cable television providers to own their own
broadcast transmission facilities and to purchase satellite capacity without
restriction. In such countries, customer access to Galaxy's services may be a
relatively simple procedure. Other countries, however, have maintained strict
monopoly regimes, so that end-users may be required to access satellite
services through a single, government-owned entity. In such markets, the
entity (often the PTT) may hold a monopoly on the ownership and operation of
facilities or on the provision of communications and/or broadcasting services
to, from and within a country, including via satellite, rendering the
provision of service from U.S.-licensed satellites more complicated.
 
  Galaxy III-R currently is the only Galaxy satellite that provides
international service, other than on an ancillary basis. GLA's local partners
have applied for and, in certain countries, have obtained authorizations from
 
                                      148
<PAGE>
 
foreign telecommunications authorities to use capacity on Galaxy III-R to
provide DTH services to various countries in Latin America. Through its local
partners, GLA currently is authorized to provide or expects to receive
authorization shortly to provide, and is providing or expects shortly to begin
providing, service throughout Latin America, although it has not yet obtained
authorization to provide service in Argentina. There can be no assurance,
however, that all of the foreign regulatory authorizations sought by GLA's
local partners, or any future customers of Galaxy operating in foreign
countries, will be granted.
 
 Intelsat Consultations
 
  Prior to receiving final licensing and launch authority and commencing
service in the United States or internationally, Galaxy must complete a
consultation process with Intelsat under Article XIV of the Intelsat
Agreement. An Intelsat consultation for a U.S.-licensed spacecraft requires
arranging for the U.S. government to consult with Intelsat to ensure that use
of the new satellite will cause Intelsat neither technical harm arising from
signal interference nor "significant economic harm."
 
  The FCC is responsible for ensuring that Galaxy has undergone the necessary
consultations and that it operates in accordance with the technical parameters
forming the basis for an Article XIV consultation. If Galaxy changes the terms
(either technical or service) of its operation in a significant way, it may
need to reconsult with Intelsat. Galaxy has requested that the FCC initiate
Intelsat consultations with respect to certain satellites and expects that
those consultations will be completed expeditiously. At the appropriate time,
Galaxy will request that the FCC initiate Intelsat consultations with respect
to those satellites for which applications presently are pending. There can be
no assurance, however, that any such consultations will be completed
successfully.
 
 International Telecommunications Union Coordination
 
  Nations register their proposed use of orbital locations with the ITU Radio
Regulations Board to ensure that there is an orderly process for accommodating
each country's needs for orbital locations. See "BUSINESS OF PANAMSAT--
Government Regulation."
 
  The U.S. government has filed with the ITU for all of Galaxy's existing and
proposed orbital locations, and the use of any of these locations will need to
be coordinated with foreign administrations that have filed for neighboring
orbital locations. For the most part, the right to use certain frequencies at
a given orbital location is determined on a "first-come, first-served" basis,
based on the date on which a country makes certain filings at the ITU.
However, the ITU has "planned" the use of certain frequency bands in a manner
that effectively reserves for various countries the right to use those
frequency bands at given locations in accordance with certain technical
parameters. The ITU has "planned" the use of the Ku-band (BSS) frequencies in
this manner and has adopted procedures that allow for countries to propose
modifications to that plan: that is, proposals for additional uses of those
frequencies that do not cause unacceptable interference with any preassigned
uses. Proposed modifications that are filed with the ITU are reviewed by the
ITU to ensure that they comply with its rules and procedures. A proposed
modification that is approved formally becomes part of the ITU's Ku-band (BSS)
plan and receives the associated regulatory protections.
 
  Galaxy's proposal to use the Ku-band (BSS) frequencies at 12 locations
requires a modification to the ITU's BSS plan. Use of those orbital positions
for Ku-band (BSS) services is subject to approval by the ITU as a modification
to its current BSS plan. The U.S. government has forwarded the required
filings to the ITU and Galaxy believes that those filings comply with ITU
requirements in all material respects. However, the ITU plans to revise the
BSS plan in the fall of 1997 and it is uncertain whether Galaxy's proposed
modifications will be approved before that time or at all. If the ITU modifies
its BSS plan, it is not clear what effect such revisions would have on
Galaxy's proposal to use the Ku-band (BSS) frequencies at 12 locations around
the world. Galaxy believes that its proposal has a very good chance of
obtaining ITU approval, but there are significant competing interests and
there can be no assurance that the ITU will approve Galaxy's proposal. See
"RISK FACTORS--Regulatory Risks."
 
  The foregoing does not purport to describe all present and proposed U.S.,
foreign and international laws and regulations relating to the satellite
industry. The changing laws, regulations and policies in the United States
 
                                      149

and other countries will continue to affect the satellite industry. Galaxy
cannot predict the impact that these changes will have on its business or
whether the general deregulatory trend observed in the United States and
certain other countries in recent years will continue. Galaxy believes that
continued deregulation would be beneficial to it, but deregulation also could
reduce the limitations facing its existing and potential new competitors.
 
EMPLOYEES
 
  As of December 31, 1996, Galaxy had 275 full-time employees. The
Engineering, Operations and Technology departments consist of 176 employees,
all of whom are located at Galaxy's Long Beach, California facilities, with
the exception of 34 employees based at Galaxy's teleports in Fillmore,
California, Castle Rock, Colorado, and Spring Creek, New York. The Sales and
Marketing department consists of 35 people. There are 64 employees involved in
providing administrative, finance, human resources, legal and public relations
services. The number of personnel is fairly stable and is not anticipated to
increase substantially over the next few years. Galaxy is not a party to any
collective bargaining agreement and believes its relations with its employees
are good.
 
PROPERTIES
 
  Galaxy's Corporate Headquarters is located in Long Beach, California. Galaxy
also has a Network Operations Center and a Satellite Operations Center and
Warehouse located in Long Beach, California. In addition, Galaxy operates
earth stations in Spring Creek, New York, Castlerock, Colorado, and Fillmore,
California. Galaxy has leased its Corporate Headquarters and Network
Operations Center through 2008. Galaxy owns its Satellite Operations Center
and Warehouse as well as the Spring Creek Earth Station. Galaxy is currently
in the process of negotiating the purchase of the Fillmore Earth Station from
Texaco Exploration and Production, Inc., and is in the process of negotiating
a lease of the Castlerock Earth Station from HE. The following table sets
forth certain information concerning Galaxy's properties and those that it
expects to purchase or lease prior to the Closing Date:

                           BUSINESS OF NEW PANAMSAT
 
  New PanAmSat, a wholly owned subsidiary of HCI, has not conducted any
business activities to date, other than those incident to its formation, its
execution of the Reorganization Agreement and related agreements and its
participation in the preparation of this Proxy Statement/Prospectus.
Immediately following the consummation of the Reorganization, New PanAmSat
will own and operate Galaxy and will own, directly and indirectly, all of the
outstanding capital stock of PanAmSat. Accordingly, the business of New
PanAmSat, operated directly and through its wholly owned subsidiary, will be
the businesses currently conducted by PanAmSat and Galaxy. See "BUSINESS OF
PANAMSAT" and "BUSINESS OF GALAXY." For a discussion of the benefits that the
PanAmSat Board believes will result from the Reorganization, see "THE
REORGANIZATION--Recommendation of the PanAmSat Board and Reasons for the
Merger."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Upon consummation of the Reorganization, New PanAmSat will collect all cash
receipts and disburse all cash payments related to the business previously
operated by Galaxy, while PanAmSat, as a wholly-owned subsidiary of New
PanAmSat, will continue to collect all cash receipts and disburse all cash
payments related to PanAmSat's business. New PanAmSat and its subsidiaries
will not participate in the cash management system utilized by HE and its
subsidiaries, and HE is not required to provide any additional funding or
financing to New PanAmSat other than the New Financing. At Closing, New
PanAmSat will have outstanding approximately $1.725 billion in long-term
indebtedness represented by the New Financing and PanAmSat will have
outstanding long-term indebtedness of approximately $626 million (as of
December 31, 1996) and the Preferred Stock with an aggregate liquidation
preference of approximately $329 million (as of December 31, 1996). Management
of PanAmSat and Galaxy expect that the consolidated operations of New PanAmSat
and its subsidiaries going forward will be financed through cash on hand
(including $60 million contributed by HE at Closing and $135 million received
by PanAmSat net of taxes in the DTH Sale), cash flow from operations and
additional vendor financing.
 
  For as long as PanAmSat's existing indebtedness and the PAS Preferred Stock
are outstanding, PanAmSat will be subject to provisions contained in the
indentures governing such indebtedness and the certificate of designation for
such preferred stock that will significantly limit PanAmSat's ability to pay
dividends or loans funds to New PanAmSat. As a result, New PanAmSat will be
restricted from using PanAmSat's cash flows to fund New PanAmSat's capital
expenditures. However, to the extent that New PanAmSat's cash on hand and cash
flow from operations of New PanAmSat alone are not sufficient to fund capital
expenditures at the New PanAmSat level, New PanAmSat will be able to either
sell assets to PanAmSat for cash or assign satellites under development to
PanAmSat which then would be developed by PanAmSat.
 
  The significant cash outlays for New PanAmSat and PanAmSat will continue to
be primarily capital expenditures related to the construction and launch of
satellites. On the Closing Date, assuming PAS-6 is successfully launched as
scheduled, PanAmSat and Galaxy together will have nine satellites under
various stages of development for which PanAmSat and Galaxy have budgeted
capital expenditures. PanAmSat will require approximately $330 million
following the Closing Date for the construction, insurance and launch of PAS-
5, PAS-6, PAS-7 and PAS-8. Similarly, Galaxy will require approximately $743
million following the Closing Date to complete the construction, insurance and
launch of Galaxy VIII-i, Galaxy X, Galaxy XI, Galaxy XII, Galaxy XIII-i and
Galaxy XIV-i. Galaxy and PanAmSat currently are discussing whether certain
changes should be made to the technical specifications and locations of
certain of their satellites under development in order to better serve the
business objectives of New PanAmSat, which changes may impact the amount and
timing of future capital expenditures made by New PanAmSat and PanAmSat. The
aggregate amount of cash needed to fund development of all of PanAmSat's and
Galaxy's satellites is expected to be funded from cash on hand and cash flow
of the consolidated operations of New PanAmSat and PanAmSat. In addition to
funding new satellites, New PanAmSat also expects to exercise the Early Buy
Out Options, which will require New PanAmSat to fund additional outlays of
approximately $152 million in 1998 and approximately $366 million in 1999. See
"BUSINESS OF GALAXY--Sale-Leaseback Arrangements." Such additional outlays
also are expected to be
 
                                      151
<PAGE>
 
funded from the cash flow from the consolidated operations of New PanAmSat and
PanAmSat. There can be no assurance, however, that New PanAmSat will be able
to fund such expenditures or any other future expenditures from the cash flow
of New PanAmSat's consolidated operations and, if it is so unable, that New
PanAmSat will be able to incur additional indebtedness sufficient to fund such
expenditures. See "RISK FACTORS--Substantial Leverage and Additional Capital
Requirements."

 (1) Other expenses relate to costs incurred in connection with the
     Reorganization Agreement.
 (2) In 1995, this reflects expenses related to the assumption by PanAmSat of
     phantom stock plans of a predecessor company and the grant of a limited
     partnership interest in the Partnership to the Executive Vice President
     of PanAmSat in connection with the corporate reorganization of PanAmSat.
     In 1996, this represents a cash bonus paid to employees who would
     otherwise have qualified for the grant of stock options under PanAmSat's
     Long-Term Stock Investment Plan. See Note 11 to Notes to the PanAmSat
     Financial Statements.
 (3) In 1992, this includes costs (net of insurance reimbursement) arising
     from damage caused by Hurricane Andrew to PanAmSat's teleport in
     Homestead, Florida.
 (4) Net of capitalized interest of $9.0 million, $41.0 million, $37.8 million
     and $39.5 million for the years ended December 31, 1993, 1994, 1995 and
     1996, respectively.
 (5) As a partnership, the Partnership was not subject to federal or state
     income taxes. Accordingly, no income taxes were deducted from net income
     on the Partnership's financial statements. However, the Partnership was
     obligated under its Partnership Agreement to make certain tax
     distributions to its partners. On March 2, 1995, the Partnership was
     converted to corporate form and, accordingly, is now subject to income
     taxes. See "BUSINESS OF PANAMSAT--Conversion and Initial Public
     Offering."

   for the year ended December 31, 1995 is based on 89,678,638 weighted
   average shares outstanding as of December 31, 1995 reflecting the IPO which
   occurred on September 21, 1995.
 (7) Represents earnings before net interest expense, income taxes,
     depreciation and amortization. EBITDA is commonly used in the
     communications industry to analyze companies on the basis of operating
     performance, leverage and liquidity. EBITDA should not be considered as a
     measure of profitability or liquidity as determined in accordance with
     generally accepted accounting principles in the statements of operations
     and cash flows.
 (8) Includes expenses related to the assumption by PanAmSat of phantom stock
     plans of a predecessor company and the grant of a limited partnership
     interest in the Partnership to the Executive Vice President of PanAmSat
     in connection with the corporate reorganization of PanAmSat of $8.3
     million for the year ended December 31, 1995 and expenses related to the
     Reorganization Agreement and a corporate compensation plan totaling $9.6
     million for the year ended December 31, 1996. EBITDA and EBITDA margin
     excluding such expenses were $74.5 million and 64% for the year ended
     December 31, 1995 and $179.7 million and 73% for the year ended December
     31, 1996. See Notes 11 and 13 of the PanAmSat Financial Statements.
 (9) Represents future payments due from customers under long-term contracts
     at the end of the periods indicated, excluding arrangements for satellite
     capacity for DTH services in Latin America. At December 31, 1996,
     approximately $22.6 million of PAS-1 customer payments, $92.4 million of
     PAS-2 customer payments, $35.6 million of PAS-3 customer payments and
     $79.2 million of PAS-4 customer payments were under contracts which are
     terminable by the customer under certain circumstances, including after a
     minimum service period. Certain contracts may also be terminated if
     certain technical performance specifications contained in the agreements,
     including useful life, are not achieved, or, at the customer's option
     after a minimum service period. Future cash payments expected from
     customers may be reduced for outage or transponder failure and may be
     further reduced for "lowest price" provisions for like transponder
     capacity given to similarly situated customers. The terms of PanAmSat's
     long-term contracts range from one year to the life of the satellite. See
     "PANAMSAT MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
     RESULTS OF OPERATIONS--Overview."
(10) Excludes, as to each of PAS-5 and PAS-6, a portion of the respective
     purchase prices which will become payable after such satellite is
     delivered and which amount may be paid immediately in cash or deferred
     over periods of up to 15 years with interest rates ranging from 8.0% to
     10.0% per annum. At December 31, 1996, these amounts aggregated
     approximately $34.5 million. A portion of the respective purchase prices
     of PAS-7 and PAS-8 may also be deferrable. PanAmSat presently intends to
     defer such payments at the time they become payable to the extent such
     deferral is permitted under the terms of its then-outstanding
     indebtedness and preferred stock. PanAmSat anticipates that if, at the
     time such payments become payable, PanAmSat is prohibited from incurring
     such indebtedness under the terms of its outstanding indebtedness or
     preferred stock, it will either seek the consent of the holders thereof
     to incur such indebtedness or will obtain funds from sources permitted
     under the terms thereof to make such payments. There can be no assurance
     that such consent will be obtained or that funds will be available to
     PanAmSat from sources permitted under the terms of its outstanding
     indebtedness and preferred stock. See Notes 6, 7 and 8 of the PanAmSat
     Financial Statements appearing elsewhere in this Proxy
     Statement/Prospectus and "BUSINESS OF PANAMSAT--PanAmSat Satellites."
(11) Under the Partnership Agreement of the Partnership, if the launches of
     PAS-2, PAS-3 and PAS-4 were not all successfully completed by December
     31, 2001, USHI would have had the right to redeem its $200.0 million
     investment in PanAmSat in 2004 for $200.0 million, less certain
     distributions paid to USHI, plus a yield thereon of 6.0% per annum. In
     the Conversion, USHI's redemption rights with respect to its interest in
     the Partnership were extinguished.
(12) Net of distributions of $16.4 million and $6.2 million for the years
     ended December 31, 1992 and 1993, respectively, and a contribution of $.7
     million for the year ended December 31, 1994. There were no distributions
     or contributions in 1995 or 1996.

  The following discussion and analysis of the financial condition and results
of operations of PanAmSat should be read in conjunction with the financial
data and the PanAmSat Financial Statements appearing elsewhere in this Proxy
Statement/Prospectus.
 
OVERVIEW
 
  PanAmSat's first satellite, PAS-1, was launched in June 1988 for service
over the Atlantic Ocean Region and is a leading satellite for television and
cable programming distribution in Latin America. PanAmSat's second satellite,
PAS-2, was launched in July 1994 for service over the Pacific Ocean Region and
is a leading satellite for programming distribution in the Asia-Pacific
region. PanAmSat's PAS-4 satellite was launched in August 1995 for service
over the Indian Ocean Region and is a leading satellite for programming
distribution in south Asia and Africa. PanAmSat's PAS-3 satellite was launched
in January 1996 for service over the Atlantic Ocean Region. PAS-3 and PAS-1
are the leading satellites for television and cable programming distribution
in Latin America. PanAmSat expects to launch two additional satellites to
serve the Atlantic Ocean Region: PAS-6 in May 1997; and PAS-5 in July 1997.
However, SS/Loral has recently informed PanAmSat of circumstances that could
result in a delay in the launch of PAS-6. See "RISK FACTORS--Risk of Delays;
Excess Weight." PanAmSat intends to launch PAS-7 and PAS-8 in early 1998. PAS-
7 and PAS-8 are expected to serve the Indian Ocean Region and the Pacific
Ocean Region, respectively. PanAmSat expects that in the future it will launch
additional satellites to meet then-anticipated customer demand. There can be
no assurance, however, that the schedule for PanAmSat's future satellite
launches will be met.
 
  At December 31, 1996, PanAmSat's long-term contracts provided for future
payments of approximately $2.4 billion, consisting of $187 million for PAS-1,
$516 million for PAS-2, $583 million for PAS-3 and $1.1 billion for PAS-4,
excluding arrangements for satellite capacity for the DTH service in Latin
America. At December 31, 1996, approximately $22.6 million of PAS-1 customer
payments, $92.4 million of PAS-2 customer payments, $35.6 million of PAS-3
customer payments and $79.2 million of PAS-4 customer payments were under
contracts which may be terminable by the customer if certain technical
performance specifications contained in the agreements, including useful life,
are not achieved or, at the customer's option, after a minimum service period.
At December 31, 1996, PanAmSat's long-term contracts, excluding arrangements
for satellite capacity for the DTH service in Latin America, were comprised of
approximately $247.8 million expected to be received in the year ending
December 31, 1997, $261.6 million expected to be received in the year ending
December 31, 1998, $262.0 million expected to be received in the year ending
December 31, 1999, $257.7 million expected to be received in the year ending
December 31, 2000 and $1,405 million expected to be received on and after
January 1, 2001. The estimated useful life of each of PAS-1, PAS-2, PAS-3 and
PAS-4 is 13, 14, 15 and 15 years from launch, respectively. PanAmSat signed
the 1996 Letter Agreement to provide services to the Latin America JVs on 48
transponders on the PAS-5 and PAS-6 satellites at a minimum value of
approximately $1.3 billion, depending upon actual useful life, of the
satellites in question, their predicted performance and their in-service
dates. For most of the transponders, this value reflects service fees that are
equal to PanAmSat's best estimate of the cost to design, construct, launch,
insure and operate the satellites and for the balance of the transponders, the
value reflects service fees that are based on a fixed price. On the cost-based
transponders, PanAmSat also could receive revenue sharing from the Latin
America JVs and the Spain Joint Venture. The backlog for the 1996 Letter
Agreement is comprised of approximately $45.9 million expected to be received
in the year ending December 31, 1997, $80.4 million expected to be received in
each of the years ending December 31, 1998, 1999 and 2000, and $927.0 million
expected to be received on and after January 1, 2001. See "BUSINESS OF
PANAMSAT--DTH Strategy." Future cash payments expected from customers may be
reduced for outage or transport failure and may be further reduced for "lowest
price" provisions for like transponder capacity given to similarly situated
customers. The terms of PanAmSat's long-term contracts range from one year to
the life of the satellite.
 
  During the construction period of each of its new satellites, and
thereafter, PanAmSat may incur increased operating expenses, including
expenditures for sales and marketing in excess of the levels previously
incurred,
 
                                      155
<PAGE>
 
increased engineering and technical expenses, as well as increased general and
administrative expenses, which increased expenses may not be offset by
additional revenues until the new satellites are successfully launched and
commence service. As a result, PanAmSat's operating income and EBITDA margins
were lower in 1994 than in 1993. However, in 1995 and 1996, EBITDA margin
increased due to a significant growth in revenues, and operating income margin
increased in 1996, and would have increased in 1995 except for the $8.3
million corporate reorganization and compensation expense related to the
assumption by PanAmSat of phantom stock plans of a predecessor company and the
grant of a limited partnership interest in the Partnership to the Executive
Vice President of PanAmSat. PanAmSat's income from operations and EBITDA in
1995 were also adversely affected by the corporate reorganization compensation
expense. Also, commencing at the in-service date of any successfully-launched
satellite, all satellite construction, launch, launch insurance, capitalized
interest and development costs for such satellite will be depreciated on a
straight-line basis over the estimated useful life of the satellite. Further,
after the in-service date of any successfully-launched satellite (or upon a
launch failure), PanAmSat will be required to expense, and no longer will be
able to capitalize, interest allocable to such satellite's construction,
launch and development costs. Interest capitalized in future periods is
dependent on the level of satellites under construction, which is expected to
vary.
 
  PanAmSat is not a party to any material currency or interest rate hedging
transactions, and substantially all of PanAmSat's long-term customer contracts
and vendor obligations are denominated in U.S. dollars.

(1) Revenues from PAS-2 for the fiscal years ended December 31, 1994, 1995 and
    1996 were $3.7 million, $29.2 million and $53.2 million, respectively.
    Revenues for PAS-4 for the fiscal years ended December 31, 1995 and 1996
    were $21.4 million and $74.7 million, respectively.
(2) EBITDA represents earnings before net interest expense, income taxes,
    depreciation and amortization. EBITDA is commonly used in the
    communications industry to analyze companies on the basis of operating
    performance, leverage and liquidity. EBITDA should not be considered as a
    measure of profitability or liquidity as determined in accordance with
    generally accepted accounting principles in the statements of operations
    and cash flows.
(3) Includes expenses of $8.3 million in 1995 related to the assumption by
    PanAmSat of phantom stock plans of a predecessor company and the grant of
    a limited partnership interest in the Partnership to an Executive Vice
    President of PanAmSat in connection with the corporate reorganization of
    PanAmSat and, in 1996, expenses of $9.6 million related to the
    Reorganization Agreement and a corporate compensation plan. EBITDA Margin
    excluding such expenses was 64% for the year ended December 31, 1995 and
    73% for the year ended December 31, 1996.
 
  PanAmSat provides satellite services primarily to the video distribution and
business communications markets. PanAmSat also provides services to the
telephony market. PanAmSat's video distribution services include the provision
of satellite capacity and services for (i) television programming
distribution, (ii) "backhaul" operations (i.e., the transmission of video
feeds from one location to another) and (iii) ad hoc
 
                                      156

services such as the transmission of special events and live news reports from
the scene of an event. PanAmSat's business communications services include (a)
the provision of satellite capacity to communications carriers that provide
private business networks for data, voice and corporate video communications
and (b) the provision of such networks and related services by PanAmSat
directly to end-users. PanAmSat's telephony services provide satellite
capacity for use in domestic (non-U.S.) and international public telephone
networks. PanAmSat's total revenues in each of these markets, and the revenues
in these markets as a percentage of total revenues, for the periods indicated

1996 COMPARED TO 1995
 
  Revenues. Total revenues for the year ended December 31, 1996 were $246.9
million, an increase of $130.7 million, or 112%, over 1995. The increase in
total revenues was due primarily to the growth in video distribution services.
 
  Video distribution services revenue was $204.8 million in the year ended
December 31, 1996, an increase of $120.9 million or 144% over 1995. The growth
in video distribution services revenue during 1996 was due primarily to the
commencement of video services on the PAS-3 satellite, and the continuing
increase in space segment leasing for video services on the PAS-2 and PAS-4
satellites.
 
  Business communications services revenue was $39.9 million in 1996, an
increase of $9.8 million, or 32% over 1995. The increase was due primarily to
commencement of service for several new data network and carrier service
contracts which originated during the past year.
 
  Telephony services revenue was $2.2 million in 1996, an increase of $0.1
million or 5% from 1995.
 
  Direct Expenses. Direct expenses were $10.5 million in the year ended
December 31, 1996, an increase of $4.8 million, as compared to $5.7 million in
1995. Direct expenses were 4% and 5% of total revenues in the years ended
December 31, 1996 and 1995, respectively.
 
  Sales and Marketing Expenses. Sales and marketing expenses were $14.0
million in the year ended December 31, 1996, an increase of $4.5 million, as
compared to $9.5 million in 1995. Sales and marketing expenses were 6% and 8%
of total revenues in the years ended December 31, 1996 and 1995, respectively.
The dollar increase in sales and marketing expenses during 1996 was primarily
attributable to PanAmSat's efforts in marketing capacity on the PAS Global
System and the pursuit of DTH opportunities worldwide.
 
  Engineering and Technical Expenses. Engineering and technical expenses were
$17.3 million in the year ended December 31, 1996, an increase of $6.6
million, as compared to $10.7 million in 1995. Engineering and technical
expenses were 7% and 9% of total revenues in the years ended December 31, 1996
and 1995, respectively. The dollar increase in engineering and technical
expenses during 1996 was due primarily to TT&C costs associated with PAS-3 and
PAS-4, as well as costs associated with contracts to provide carrier
monitoring services.
 
  General and Administrative Expenses. General and administrative expenses
were $25.3 million in the year ended December 31, 1996, an increase of $9.6
million, as compared to $15.7 million in 1995. General and administrative
expenses were 10% of total revenues in 1996 as compared to 14% of total
revenues in 1995. The dollar increase in general and administrative expenses
during 1996 was due primarily to increased costs of $6.4 million associated
with in-orbit insurance on PAS-3 and PAS-4. The remaining increase of $3.2
million primarily results from additional personnel and other administrative
costs associated with PanAmSat's expansion.
 
 
                                      157

  Depreciation and Amortization. Depreciation and amortization was $61.3
million in the year ended December 31, 1996, an increase of $27.9 million, or
84%, as compared to $33.4 million for the year ended 1995. Depreciation and
amortization was 25% of total revenues in 1996 as compared to 29% of total
revenues in 1995. The dollar increase in 1996 was due primarily to
depreciation expense associated with PAS-3 and PAS-4.
 
  Compensatory Programs. Compensatory program expense was $4.9 million in the
year ended December 31, 1996 compared to $8.3 million for the year ended
December 31, 1995, a decrease of $3.4 million. Compensatory program expense
during 1996 represents a cash bonus paid to employees who would otherwise have
qualified for the grant of stock options under the Company's Long-Term Stock
Investment Plan. Compensatory program expense during 1995 is related to the
assumption by the Company of phantom stock plans of a predecessor company and
the grant of a limited partnership interest in the Partnership to the
Executive Vice President of the Company.
 
  Reorganization Costs. Reorganization costs of $4.8 million for the year
ended December 31, 1996 consist of legal, accounting and investment banking
fees associated with the Agreement and Plan of Reorganization with Hughes
announced in September 1996.
 
  Income From Operations. Income from operations was $108.8 million for the
year ended December 31, 1996, an increase of $76.0 million, as compared to
$32.8 million in 1995. Income from operations was 44% and 28% of total
revenues in the years ended December 31, 1996 and 1995, respectively. The
dollar increase in income from operations during 1996 was due primarily to the
increase in video distribution services revenues.
 
  Interest. Interest income was $24.3 million for the year ended December 31,
1996 compared to $20.6 million in the prior year. The dollar increase in
interest income during 1996 is a result of interest earned on proceeds from
the offerings of the Preferred Stock and the Common Stock in 1995 that had not
been applied to satellite systems under development. Interest expense, net of
capitalized interest, increased from $19.0 million in the year ended December
31, 1995 to $24.9 million during the year ended December 31, 1996. This
increase in interest expense is due to interest expense incurred on satellite
incentive obligations and additional accretion of the Discount Notes.
 
  Income Before Income Taxes. Income before income taxes was $108.2 million
for the year ended December 31, 1996, an increase of $73.8 million, as
compared to $34.4 million in 1995. Income before income taxes was 44% and 30%
of total revenues in the years ended December 31, 1996 and 1995, respectively.
The dollar increase in income before income taxes during 1996 was due
primarily to the increase in video distribution services revenues.
 
  Income Taxes. PanAmSat had an income tax provision of $46.4 million for the
year ended December 31, 1996 compared to $16.8 million for the year ended
December 31, 1995. The increase in income taxes during 1996 was due to the
increase in income before income taxes.
 
  Net Income. Net income was $61.7 million for the year ended December 31,
1996, an increase of $44.2 million, as compared to $17.5 million in 1995. Net
income was 25% and 15% of total revenues in the years ended December 31, 1996
and 1995, respectively. The dollar increase in net income during 1996 was due
primarily to the increase in video distribution services revenues.
 
  Preferred Stock Dividend. PanAmSat had preferred stock dividends of $41.4
million for the year ended December 31, 1996, an increase of $15.4 million, as
compared to $26.0 million in 1995. The preferred stock dividends are a result
of the issuance of the Preferred Stock on April 21, 1995.
 
  Net Income (Loss) To Common Shares. Net income (loss) to common shares was
$20.3 million for the year ended December 31, 1996, an increase of $28.7
million, as compared to ($8.4) million in 1995. Net income (loss) to common
shares was 8% and (7%) of total revenues in the years ended December 31, 1996
and 1995, respectively. The dollar increase in net income (loss) to common
shares during 1996 was due primarily to the increase in video distribution
services revenues.

  EBITDA. EBITDA was $170.1 million for the year ended December 31, 1996, an
increase of $103.9 million, or 157%, as compared to $66.2 million in 1995.
EBITDA was 69% of total revenues in 1996 as compared to 57% of total revenues
in 1995. The dollar increase in EBITDA during 1996 was due primarily to the
increase in video distribution services revenues.
 
1995 COMPARED TO 1994
 
  Revenues. Total revenues for the year ended December 31, 1995 were $116.2
million, an increase of $52.5 million, or 82%, over 1994. The increase in
total revenues was due primarily to the growth in video distribution services.
 
  Video distribution services revenue was $83.9 million in the year ended
December 31, 1995, an increase of $45.0 million, or 116%, over 1994. The
growth in video distribution services revenue during 1995 was due primarily to
revenues from video services on PAS-2 and the commencement of revenues from
video services on PAS-4.
 
  Business communications services revenue was $30.1 million in 1995, an
increase of $7.7 million, or 34%, over 1994. The increase was due primarily to
commencement of service for several new IDS network and carrier service data
contracts which originated during the past year.
 
  Telephony services revenue was $2.1 million in 1995, a decrease of $0.4
million, or 16%, from 1994.
 
  Direct Expenses. Direct expenses were $5.7 million and $4.3 million in the
years ended December 31, 1995 and 1994, respectively. Direct expenses were 5%
and 7% of total revenues in 1995 and 1994, respectively.
 
  Sales and Marketing Expenses. Sales and marketing expenses were $9.5 million
in the year ended December 31, 1995, an increase of $2.3 million, as compared
to $7.2 million in 1994. Sales and marketing expenses were 8% and 11% of total
revenues in the years ended December 31, 1995 and 1994, respectively. The
dollar increase in sales and marketing expenses during 1995 was primarily
attributable to PanAmSat's efforts in marketing capacity on its new
satellites.
 
  Engineering and Technical Expenses. Engineering and technical expenses were
$10.7 million in the year ended December 31, 1995, an increase of $4.9
million, as compared to $5.8 million in 1994. Engineering and technical
expenses were 9% of total revenues for both 1995 and 1994. The dollar increase
in engineering and technical expenses during 1995 was due primarily to
increased personnel costs associated with its new teleport facilities and TT&C
costs associated with PAS-2 and PAS-4.
 
  General and Administrative Expenses. General and administrative expenses
were $15.7 million in the year ended December 31, 1995, an increase of $5.9
million, as compared to $9.8 million in 1994. General and administrative
expenses were 14% of total revenues in 1995 as compared to 15% of total
revenues in 1994. The dollar increase in general and administrative expenses
during 1995 was due primarily to increased costs of $4.6 million associated
with in-orbit insurance on PAS-2 and PAS-4. The remaining increase of $1.3
million primarily results from additional personnel and other administrative
costs associated with PanAmSat's expansion.
 
  Depreciation and Amortization. Depreciation and amortization was $33.4
million in the year ended December 31, 1995, an increase of $17.1 million, or
105%, as compared to $16.3 million for the year ended 1994. Depreciation and
amortization was 29% of total revenues in 1995 as compared to 26% of total
revenues in 1994. The dollar increase in 1995 was due primarily to
depreciation expense associated with PAS-2 and PAS-4, the latter being placed
in service during 1995.
 
  Compensatory Programs. Compensation expense related to corporate
reorganization of $8.3 million in 1995 related to the assumption by PanAmSat
of the phantom stock plans of a predecessor company and the grant of a limited
partnership interest in the Partnership to the Executive Vice President of
PanAmSat.

  Income From Operations. Income from operations was $32.8 million for the
year ended December 31, 1995, an increase of $12.4 million, as compared to
$20.4 million in 1994. Income from operations was 28% and 32% of total
revenues in the years ended December 31, 1995 and 1994, respectively. The
dollar increase in income from operations during 1995 was due primarily to the
increase in video distribution services revenues.
 
  Interest. Interest income was $20.6 million for the year ended December 31,
1995 compared to $7.2 million in the prior year. The dollar increase in
interest income during 1995 is a result of interest earned on proceeds from
the offerings of the Preferred Stock and the Common Stock in 1995 that had not
been applied to satellite systems under development. Interest expense, net of
capitalized interest, increased from $9.6 million in the year ended December
31, 1994 to $19.0 million during the year ended December 31, 1995. This
increase in interest expense is due to interest expense incurred on satellite
incentive obligations and additional accretion of the Discount Notes, coupled
with decreased amounts of interest eligible for capitalization on construction
in progress in 1995.
 
  Income Before Income Taxes. Income before income taxes was $34.4 million for
the year ended December 31, 1995, an increase of $16.4 million, as compared to
$18.0 million in 1994. Income before income taxes was 30% and 28% of total
revenues in the years ended December 31, 1995 and 1994, respectively. The
dollar increase in income before income taxes during 1995 was due primarily to
the increase in video distribution services revenues.
 
  Income Taxes. PanAmSat had an income tax provision of $16.8 million for the
year ended December 31, 1995 and did not have any income tax provision for the
prior year. The 1995 provision is the result of the Conversion of PanAmSat
from a partnership to a corporation on March 2, 1995.
 
  Net Income. Net income was $17.5 million for the year ended December 31,
1995, a decrease of $5 million, as compared to $18.0 million in 1994. Net
income was 15% and 28% of total revenues in the years ended December 31, 1995
and 1994, respectively.
 
  Preferred Stock Dividend. PanAmSat had preferred stock dividends of $26.0
million for the year ended December 31, 1995 and did not have any preferred
stock dividends for the prior year. The preferred stock dividends in 1995 are
a result of the issuance of the PAS Preferred Stock on April 21, 1995.
 
  Net Income (Loss) To Common Shares. Net income (loss) to common shares was
$(8.4) million for the year ended December 31, 1995, a decrease of $26.4
million, as compared to $18.0 million in 1994. Net income (loss) to common
shares was (7%) and 28% of total revenues in the years ended December 31, 1995
and 1994, respectively. The dollar decrease in net income (loss) to common
shares during 1995 was due primarily to the PAS Preferred Stock dividend
requirement.
 
  Pro Forma Net Income. Pro forma net income was $18.8 million for the year
ended December 31, 1995, an increase of $8.0 million, as compared to $10.8
million in 1994. Pro forma net income was 16% and 17% of total revenues in the
years ended December 31, 1995 and 1994, respectively.
 
  Pro Forma Net Income (Loss) To Common Shares. Pro forma net income (loss) to
common shares was $(7.2) million for the year ended December 31, 1995, a
decrease of $18.0 million, as compared to $10.8 million in 1994. Net income
(loss) to common shares was (6%) and 17% of total revenues in the years ended
December 31, 1995 and 1994, respectively. The dollar decrease in pro forma net
income (loss) to common shares during 1995 was due primarily to the PAS
Preferred Stock dividend requirement.
 
  EBITDA. EBITDA, excluding the $8.3 million corporate reorganization
compensation charge, was $74.5 million for the year ended December 31, 1995,
an increase of $37.8 million, or 103%, as compared to $36.7 million in 1994.
EBITDA, excluding the $8.3 million corporate reorganization compensation
charge, was 64% of total revenues in 1995 as compared to 58% of total revenues
in 1994. The dollar increase in EBITDA was due primarily to the increase in
video distribution services revenues.

LIQUIDITY AND CAPITAL RESOURCES
 
  Since its inception, PanAmSat and its predecessors have financed their
operations through a combination of debt and equity financing, vendor
financing, bank financing, equipment leases and cash flow from operations. On
August 5, 1993, PanAmSat completed the sale of $175 million aggregate
principal amount of the Senior Secured Notes and $460.2 million aggregate
principal amount of the Discount Notes in a public offering and received net
proceeds of approximately $425.5 million. The original PAS-3 satellite was
destroyed during a launch failure on December 1, 1994. PanAmSat collected in
1995 the insurance proceeds in the amount of $214.0 million for the original
PAS-3 satellite. On April 21, 1995, PanAmSat completed the sale of 275,000
shares of the PAS Preferred Stock in a public offering and received net
proceeds of approximately $261.8 million. On September 27, 1995, the public
offering of 18,920,000 shares of the PAS Ordinary Common Stock was completed.
Of such shares, 14,324,324 shares of PAS Ordinary Common Stock were sold by
PanAmSat and 4,595,676 shares of PAS Ordinary Common Stock were sold by
certain selling stockholders. PanAmSat received net proceeds of approximately
$229.1 million from its sale of shares of PAS Ordinary Common Stock, but did
not receive any of the proceeds from the sale of shares by the selling
stockholders.
 
  The total cost for the construction and launch of PAS-5 and PAS-6, including
launch insurance, certain components for spare satellites, ground facilities
and related development expenses, is estimated to be approximately $473.0
million. PanAmSat expects to fund $296.3 million of such costs with the net
proceeds of the offering of the PAS Preferred Stock and $70.0 million of
vendor financing. The balance of such costs and any additional costs due to
cost overruns, delays or other unanticipated expenses is anticipated to be
funded from future cash flow from operations and cash on hand.
 
  The total cost for the construction and launch of PAS-7 and PAS-8, including
launch insurance, ground facilities and related development expenses (but
excluding capitalized interest expense), is estimated to be approximately
$420.0 million. PanAmSat expects to fund $224.6 million of such costs with the
net proceeds to it from the offering of the PAS Ordinary Common Stock. The
balance of such costs and any additional costs due to cost overruns, delays or
other unanticipated expenses is expected to be funded from vendor financing
and future cash flow from operations.
 
  PanAmSat believes that the net proceeds to it from the offerings of PAS
Preferred Stock and PAS Ordinary Common Stock, vendor financing, future cash
flow from operations (assuming PAS-5 and PAS-6 are successfully launched and
commence service on the schedule currently contemplated) and cash on hand will
be sufficient to fund PanAmSat's operations, its remaining costs for the
construction and launch of PAS-5 and PAS-6, its anticipated minimum
contractual commitments for the construction and launch of PAS-7 and PAS-8, as
well as to pursue international opportunities for DTH services which may be
identified by PanAmSat in the future. Any additional costs due to cost
overruns, delays or other unanticipated expenses are expected to be funded
from additional vendor financing and future cash flow from operations. There
can be no assurance, however, that PanAmSat's assumptions with respect to the
construction and launch costs for PAS-5, PAS-6, PAS-7 or PAS-8 will be
correct, that under the terms of PanAmSat's then-outstanding indebtedness and
preferred stock it will be permitted to incur all of the vendor financing
available to it, or that additional vendor financing and PanAmSat's future
cash flow from operations will be sufficient to cover any shortfall in funding
for PAS-5, PAS-6, PAS-7 and PAS-8, or any such additional costs, or to pursue
international opportunities for DTH services. The ability of PanAmSat to incur
any additional debt financing will be subject to the terms of PanAmSat's
outstanding indebtedness and preferred stock. There can be no assurance that
PanAmSat will be successful in obtaining such additional financing in the
amounts or on terms acceptable to PanAmSat. The failure to obtain such
financing could have a material adverse effect on PanAmSat's operations and
its ability to accomplish its business plan. See "RISK FACTORS--Substantial
Leverage and Additional Capital Requirements." For a discussion of the
liquidity and capital requirements of PanAmSat as a portion of the business of
New PanAmSat following the Closing, see "BUSINESS OF NEW PANAMSAT--Liquidity
and Capital Resources."
 
  Cash flows provided by operating activities increased to $177.7 million in
the year ended December 31, 1996, from $95.0 million in the year ended
December 31, 1995, an increase from $26.1 million in the year ended
 
                                      161
<PAGE>
 
December 31, 1994. The increase in cash flows in 1996 was due primarily to the
significant growth in revenues and noncash charges. The increase in cash flows
in 1995 was due primarily to increases in prepaid service revenue related to
service contracts for PAS-4 and PAS-2 and noncash charges.
 
  Net cash used in investing activities decreased to $186.2 million in the
year ended December 31, 1996, from $594.3 million in the year ended December
31, 1995, an increase from $63.1 million in the year ended December 31, 1994.
The 1996 decrease primarily reflects $280.9 million of expenditures for
satellite systems under development partially funded by $117.2 million of
proceeds from maturity of marketable securities. This compares to $333.1
million in expenditures for satellite systems under development and $488.8
million of purchases of marketable securities during 1995 partially funded
with $191.1 million of insurance proceeds collected on the launch failure of
the original PAS-3 satellite. The 1995 increase primarily reflects the
insurance proceeds received in the amount of $191.1 million (net of payments
made directly to the satellite vendor) and the net proceeds of the offering of
PAS Preferred Stock and PAS Ordinary Common Stock used to fund $333.1 million
in expenditures for the new satellite system under development and $488.8
million in expenditures used to purchase marketable securities. This compares
to $300.2 million in expenditures for the satellite system under development
during 1994 partially funded with $247.8 million from maturity of marketable
securities. Expenditures on other property and equipment, primarily at
PanAmSat's teleports in Homestead, Florida, Ellenwood, Georgia and Napa,
California were $22.3 million, $13.5 million and $10.5 million in 1996, 1995,
and 1994, respectively.
 
  Net cash used in financing activities decreased to $3.6 million in the year
ended December 31, 1996, from $490.1 million provided by financing activities
in the year ended December 31, 1995, an increase from $48.5 million provided
by financing activities in the year ended December 31, 1994. The 1996 decrease
reflects $3.7 million in repayments of long-term debt for the year ended
December 31, 1996 compared to $2.1 million of repayments of long-term debt
during 1995 funded by $263.4 million of net proceeds collected on the offering
of PAS Preferred Stock and $228.8 million of net proceeds collected on the
issuance of PAS Ordinary Common Stock. The remaining net proceeds were used to
purchase marketable securities. The 1995 increase was primarily attributable
to the issuance of 275,000 shares of Preferred Stock by PanAmSat in April 1995
yielding net proceeds of $263.4 million (excluding related costs incurred in
the prior year) and the issuance of 14,324,324 shares of PAS Ordinary Common
Stock yielding net proceeds of $228.8 million.

           GALAXY MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis of the financial condition and results
of operations of Galaxy should be read in conjunction with the financial data
and the Galaxy Financial Statements appearing elsewhere in this Proxy
Statement/Prospectus.
 
OVERVIEW
 
  Galaxy's business consists primarily of providing satellite transponder
capacity for video, audio and data communications applications to cable
television programmers, broadcast television programmers, DTH service
providers and business communications customers. At December 31, 1996, Galaxy
operated a fleet of ten commercial geostationary fixed service satellites,
nine of which primarily serve the United States and one of which serves both
the United States and Latin America. Galaxy also provides satellite TT&C
services for its own satellite fleet as well as for other satellite capacity
providers.
 
  Galaxy's revenues are composed of revenues from video distribution
(primarily cable television, broadcast television and DTH services
distribution), revenues from business communications and revenues from
satellite services and other (primarily TT&C, occasional-use satellite
capacity, backup satellite capacity and capacity on two additional
satellites). The table below summarizes the composition of revenues for each
of the periods indicated:

TRANSPONDERS IN SERVICE AND AVAILABLE
 
  At December 31, 1996, Galaxy had a total of 283 commercial transponders in
service, an increase of 72 transponders over the total number in service at
December 31, 1995. This increase was attributable to Galaxy III-R and Galaxy
IX being placed in service during 1996. At December 31, 1996, 96% of Galaxy's
283 commercial transponders had been sold or committed. For purposes of the
discussion herein, the term "transponders in service" refers to the number of
operational transponders with which satellites in orbit are physically
equipped, excluding spares but including reserve transponders, whereas the
term "available transponders" refers to the number of transponders in service
that have not been sold outright or committed under a sales-type lease or an
operating lease of at least one year in duration from the date of such
determination. While the discussion herein describes customer contracts only
in terms of whole transponders, Ku-band customers may enter into time-share
arrangements for the utilization of partial transponder capacity. The
following table presents the number of commercial transponders in Galaxy's
fleet placed in service and removed from service for each of the periods
indicated:

SATELLITE CAPACITY CONTRACTS
 
  Galaxy's satellite capacity is priced on a contract rather than a tariff
basis. Galaxy is not a common carrier and consequently is not required to
provide service to all customers on uniform terms and is not subject to any
rate of return limitations or financial regulation. Galaxy contracts with
customers for the use of a specific amount of transponder capacity, typically
on a particular satellite, under contracts structured as: (i) outright sales,
(ii) sales-type leases or (iii) operating leases. The table below summarizes
the number of transponders sold outright under contracts or committed under
leases for satellites placed into service during each of the periods

  Galaxy's method of accounting for each type of contract is as follows:
 
  Outright Transponder Sale. Pursuant to a transponder sale contract, a
customer may purchase outright all rights and title to a transponder. At
December 31, 1996, Galaxy had sold outright 51 of the 283 commercial
transponders then in service. In connection with an outright sale, Galaxy
recognizes the sale proceeds as revenue and records as cost of sales the cost
basis of the transponder sold. In circumstances where transponders sold
outright are aboard a satellite that has not yet been placed into service, the
sale is recognized for accounting purposes using the percentage-of-completion
method based on costs incurred. Contracts for the outright sale of a
transponder include a TT&C service agreement with Galaxy. The periodic
payments under these service agreements are recognized as revenue when earned
and are included in Satellite Services and Other revenues.
 
  Sales-Type Lease. Sales-type leases result when a customer enters into a
lease contract which, by virtue of its terms at the inception of the lease, is
accounted for by Galaxy as a sale. At December 31, 1996, Galaxy had entered
into sales-type leases with respect to 41 of its 283 commercial transponders
then in service. Sales-type leases are not terminable or preemptible (except
for certain unlikely specified events) and have a term equal to at least 75%
of the estimated remaining useful life of the satellite. At the time that a
customer enters into a sales-type lease, Galaxy recognizes the net present
value of the future minimum lease payments as revenue from sales-type leases
with a corresponding increase to net investment in sales-type leases. The cost
basis of the
 
                                      165
<PAGE>
 
transponder is charged to cost of sales in a manner similar to an outright
sale. During the term of the lease, Galaxy recognizes, in each respective
period, that portion of the periodic lease payment deemed to be attributable
to interest income as revenues from sales-type leases. The balance of the
periodic payments is deemed to be payment of principal and is recognized as a
reduction of net investment in sales-type leases. In circumstances where
transponders sold pursuant to a sales-type lease are aboard a satellite that
has not yet been placed into service, the sale is recognized for accounting
purposes using the percentage-of-completion method based on costs incurred. On
occasion, in response to customer credit issues which may arise or be
identified subsequent to entering into a sales-type lease, Galaxy will
establish specific allowances for doubtful accounts. The provision for
doubtful accounts is included in Selling, General and Administrative Expenses.
The allowances are related to specific customers, based upon the individual
circumstances of each customer at that time, and may be wholly or partially
reversed when the specific circumstances subsequently improve. The table below
summarizes the net investment in sales-type lease activity for each of the
periods indicated:

</TABLE>
 
  In conjunction with each sales-type lease agreement, Galaxy also enters into
a TT&C service agreement. The periodic payments under these service agreements
are recognized as revenue when earned and are included in Satellite Services
and Other revenues.
 
  Operating Lease. For transponders contracted under operating leases,
periodic lease payments are recognized as revenues from operating leases on a
straight-line basis over the term of the lease. At December 31, 1996, Galaxy
had entered into operating leases with respect to 180 of the 283 commercial
transponders then in service. Galaxy enters into operating leases of
transponder capacity on both a preemptible and non-preemptible basis. In
particular, Galaxy employs Galaxy VI to provide in-orbit backup for C-band
transponder capacity. Galaxy also maintains reserve Ku-band transponders
aboard certain other Galaxy satellites to provide customers with backup
capacity in the event of a Ku-band transponder failure, to the extent that no
on-board spare transponder is available. Galaxy offers customers priority
access to backup transponder capacity for a monthly fee. Backup service
revenue is included in Satellite Services and Other revenues. Subject to a
transponder failure or other situation that would require Galaxy to switch
customers to such backup capacity, that capacity is offered to other customers
on a preemptible basis at reduced rates. Preemptible service contracts are
accounted for as operating leases.
 
BACKLOG
 
  "Backlog" represents the future cash payments which Galaxy's management
believes are likely to be received by Galaxy from operating and sales-type
leases, TT&C and satellite services contracts. Backlog for satellite services
includes cash payments received pursuant to agreements or arrangements ranging
from one year to the life of the satellite. As Galaxy has expanded its
satellite fleet, backlog has increased substantially. Representative of the
high demand for transponder capacity, the transponder capacity on the most
recent Galaxy satellites has been completely sold out prior to the launch of
such satellites.
 
  At December 31, 1996, Galaxy's backlog of future cash payments totaled
approximately $3,399 million, of which approximately $359.2 million
(representing the net present value of future cash payments from sales-type
leases) had previously been recognized by Galaxy as revenue. Galaxy's backlog
at December 31, 1996 included (i) approximately $900.0 million of future cash
payments under an operating lease agreement with a related party
 
                                      166
<PAGE>
 
(with respect to the lease of all transponder capacity on Galaxy VIII-i) that
Galaxy's management believes will be executed by April 30, 1997, (ii)
approximately $132.3 million of cash payments for (a) such related party's
continued use of transponder capacity on Galaxy III-R through the date on
which such related party's lease of Galaxy VIII-i begins and (b) the provision
to such related party of in-orbit back-up capacity on Galaxy III-R during the
term of the VIII-i lease, and (iii) approximately $240.0 million of cash
payments under anticipated follow-on leases by existing customers on SBS-5 and
SBS-6 of transponder capacity on Galaxy X and Galaxy XI, which satellites will
be located at the same orbital locations presently occupied by SBS-5 and SBS-
6. Galaxy's backlog at December 31, 1996 included an aggregate of
approximately $1,080 million of cash payments under agreements or arrangements
with entities affiliated with Galaxy (including the related-party arrangements
described in the preceding sentence). Galaxy's backlog of future cash payments
at December 31, 1996 was comprised of approximately $345.7 million expected to
be received in the year ending December 31, 1997, $404.7 million expected to
be received in the year ending December 31, 1998, $355.1 million expected to
be received in the year ending December 31, 1999, $346.4 million expected to
be received in the year ending December 31, 2000 and $1,946.8 million expected
to be received on and after January 1, 2001. At December 31, 1995, Galaxy's
backlog totaled approximately $3,152.1 million, which amount was comprised of
similar types of future payments as described in the second preceding
sentence. The net increase of approximately $246.9 million in backlog from
December 31, 1995 to the same date in 1996 was due primarily to Galaxy's
obtaining additional customer commitments for Galaxy X, which is scheduled for
launch in 1998.
 
RESULTS OF OPERATIONS
 
1996 COMPARED TO 1995
 
  Revenues. Revenues increased $96.7 million, or 25.0%, to $482.8 million in
1996 from $386.1 million in 1995. Cable, broadcast and DTH distribution
revenues increased $78.5 million, or 33.3%, to $314.4 million in 1996 from
$235.9 million in 1995, principally as a result of additional transponder
capacity with the successful launch of Galaxy III-R and Galaxy IX. Business
communications revenues increased $28.0 million, or 28.5%, to $126.4 million
in 1996 from $98.4 million in 1995. The increase was primarily due to an
increase in the full and occasional use of SBS 6, Galaxy IV and Galaxy VII Ku-
band transponders. Satellite Services and Other revenues decreased $9.8
million, or 18.9%, to $42.0 million in 1996 from $51.8 million in 1995
principally due to a decrease in ground service sales.
 
  The revenue increase can also be analyzed based on the type of agreement.
Revenues from sales and sales-type leases decreased slightly to $131.2 million
in 1996 from $133.4 million in 1995. The slight decrease was attributable to a
lower volume in 1996 relative to 1995 of outright sales and sales-type leases
of transponders previously placed in service, offset by higher interest income
on sales-type leases and sales of transponders on Galaxy X recognized using
the percentage-of-completion method. The lower volume of outright sales and
sales-type leases in 1996 primarily reflects a decrease in available in-orbit
C-band transponder capacity, which is typically purchased outright or via
sales-type leases by cable video providers. Available in-orbit C-band
transponder capacity is not expected to increase in the near term, accordingly
outright sales and sales-type lease activity is expected to remain at levels
similar to 1996. Revenues from operating leases of transponders increased
$92.5 million, or 50.1%, to $277.1 million in 1996 from $184.6 million in
1995, due primarily to additional transponder capacity placed in service with
the successful launch of Galaxy III-R and Galaxy IX in 1996, including
revenues received from a related party for certain Galaxy III-R transponder
leases. Related party revenues from Galaxy III-R transponder operating leases
are expected to remain constant in the near term, then subsequently increase
with the transfer of service to Galaxy VIII-i as noted above under "Backlog."
This transponder operating lease activity represents the only currently
expected material prospective interaction between Galaxy and the other
business activities retained by HCI.
 
  Cost of Outright Sales and Sales-Type Leases of Transponders. Cost of
outright sales and sales-type leases of transponders increased $3.4 million,
or 6.9%, to $53.0 million in 1996 from $49.6 million in 1995, reflecting
relatively constant margins on transponder sales and sales-type leases.
 
 
                                      167

  Direct Operating Costs. Direct operating costs increased $4.9 million, or
16.4%, to $34.8 million for the year ended December 31, 1996 from $29.9
million for the year ended December 31, 1995 principally due to an increase in
TT&C costs related to Galaxy III-R and Galaxy IX which were launched in 1996.
 
  Selling, General, Administrative Expenses. Selling, general and
administrative expenses increased slightly to $34.1 million for the year ended
December 31, 1996 from $30.1 million for the year ended December 31, 1995
principally due to an increase in the provision for doubtful accounts.
 
  Leaseback Expenses, Net of Deferred Gain. Leaseback expenses, net of
deferred gain, increased $23.3 million, or 63.7%, to $59.9 million for the
year ended December 31, 1996 from $36.6 million for the year ended December
31, 1995. This increase in leaseback expense, net of deferred gain, was due to
the sale-leaseback of Galaxy III-R in 1996.
 
  Depreciation and Amortization. Depreciation decreased $18.0 million, or
23.5%, to $58.5 million for the year ended December 31, 1996, from $76.5
million for the year ended December 31, 1995, due primarily to accelerated
depreciation in 1995 attributable to a reduction in the expected useful
lifetime of one noncommercial satellite resulting from a customer's decision
not to exercise a lease renewal option, partially offset by additional
depreciation associated with the launch and placement in service of Galaxy
III-R. For each of the periods noted, the amortization of goodwill was $3.3
million.
 
  Other Income. Other income decreased $5.7 million to $2.2 million for the
year ended December 31, 1996 from $7.9 million for the year ended December 31,
1995, primarily due to non-recurring revenue earned in 1995 for providing
services to General Motors.
 
  Income Tax Expense. The effective tax rate for each of the two years ended
December 31, 1996 and 1995, respectively, was 37.5%, reflecting the U.S.
federal, state and local income taxes reduced for foreign sales corporation
benefits.
 
1995 COMPARED TO 1994
 
  Revenues. Revenues increased $57.9 million, or 17.6%, to $386.1 million in
1995 from $328.2 million in 1994. Video distribution revenues increased $69.1
million, or 41.4%, to $235.9 million in 1995 from $166.8 million in 1994,
principally due to the higher demand for Ku-band transponders. Business
communications revenues decreased $8.6 million, or 8.0%, to $98.4 million in
1995 from $107.0 million in 1994, principally as a result of a reduction in
full and occasional use of SBS 6, Galaxy IV and Galaxy VII Ku-band
transponders. Satellite Services and Other revenues decreased $2.6 million, or
4.8%, to $51.8 million in 1995 from $54.4 million in 1994 due to a decrease in
foreign ground service sales.
 
  Sales and sales-type lease revenues increased $10.5 million, or 7.5%, to
$149.7 million from $139.2 million in 1994. The increase reflects higher
volume of sales and sales-type leases of transponders previously placed in
service and higher amounts of interest income on sales-type leases, which more
than offset sales recognized in 1994 on Galaxy I-R using the percentage-of-
completion method. Revenues from operating leases increased $50.0 million, or
37.1%, to $184.6 million in 1995 from $134.6 million in 1994. This increase
resulted principally from growth in the Ku-band market.
 
  Cost of Sales and Sales-Type Leases. Cost of sales and sales-type leases
increased to $49.6 million in 1995 from $45.7 million in 1994, reflecting
stable operating margins on transponder sales and sales-type leases.
 
  Direct Operating Costs. Direct operating costs decreased $3.7 million, or
11.0%, to $29.9 million from $33.6 million for the years ended December 31,
1995 and 1994, respectively.
 
  Selling, General and Administrative Expenses. In 1995, selling, general and
administrative expenses decreased $21.5 million, or 41.7%, to $30.1 million
from $51.6 million in 1994, primarily due to a provision for doubtful accounts
established in 1994 related to specific customers committed under sales-type
lease arrangements.
 
  Leaseback Expenses, Net of Deferred Gain. Leaseback expenses, net of
deferred gain, remained relatively constant for each of the years ended
December 31, 1995 and 1994.

  Depreciation and Amortization. Depreciation increased $22.4 million, or
41.4%, to $76.5 million for the year ended December 31, 1995 from $54.1
million for the year ended December 31, 1994, due primarily to a reduction in
the expected useful lifetime of one noncommercial satellite resulting from a
customer's decision not to exercise a lease renewal option. For each of the
periods noted, the amortization of intangible assets was $3.3 million.
 
  Other Income. Other income increased $4.0 million to $7.9 million for the
year ended December 31, 1995 from $3.9 million for the year ended December 31,
1994, primarily due to non-recurring revenue earned in 1995 for providing
services to General Motors.
 
  Income Tax Expense. The effective tax rate for each of the years ended
December 31, 1995 and 1994 was 37.5%, reflecting the U.S. federal, state and
local income taxes reduced for foreign sales corporation benefits.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Galaxy participates in the cash management system utilized by HE and its
subsidiaries, which collects all cash receipts and disburses all cash payments
on behalf of Galaxy. The net cash supplied or required by Galaxy is treated as
net distributions to or contributions from HE and is included in the net
investment of HE reflected as "Parent Company's Net Investment" on Galaxy's
Balance Sheet. Since its inception, Galaxy has financed its operations through
a combination of cash flow from operations, proceeds from the sale and
leaseback of satellite transponders and investment by HE. The significant cash
outlays of Galaxy are primarily capital expenditures related to the
construction and launch of satellites.
 
  Galaxy's cash receipts from operations primarily derive from contracts with
customers for a specific amount of transponder capacity structured as: (i)
outright sales, (ii) sales-type leases or (iii) operating leases. The
following tables reconcile Galaxy's revenues to its total cash receipts from
customers by type of contract:

  Cash Receipts From Customers. Cash receipts from customers increased $126.8
million, or 43.3%, to $419.9 million for the year ended December 31, 1996 from
$293.1 million for the year ended December 31, 1995. The increase was
primarily attributable to 72 new transponders placed in service and committed
in 1996, plus the outright sale or commitment under sales-type and operating
leases of seven previously available transponders.
 
  Cash receipts from customers increased $20.7 million, or 7.6%, to $293.1
million for the year ended December 31, 1995, from $272.4 million for the year
ended December 31, 1994. The increase was primarily attributable to the
outright sale or commitment under sales-type and operating leases in 1995 of
37 previously available transponders. This increase of 37 transponders was
offset by the retirement of 24 previously sold transponders for a net addition
of 13 sold and committed transponders.
 
 
                                      169
<PAGE>
 
  Net Cash Provided by Operating Activities. Net cash provided by operating
activities was $165.9 million, $93.8 million and $115.6 million for the years
ended December 31, 1996, 1995, and 1994, respectively.
 
  Cash flows from operations increased $72.1 million, or 76.9%, to $165.9
million for the year ended December 31, 1996 from $93.8 million for the year
ended December 31, 1995. The increase was primarily attributable to increased
cash receipts from customers on additional transponders committed under sales-
type and operating leases in 1996. Cash flows from operations decreased $21.8
million, or 18.9%, to $93.8 million for the year ended December 31, 1995, from
$115.6 million for the year ended December 31, 1994. The decrease was
primarily attributable to higher cash collections in early 1994 due to the
completion and placement in service of Galaxy I-R and an increase in 1995 tax
payments caused by reductions in temporary differences associated with
depreciation on satellites, which more than offset increases in cash receipts
from customers attributable to newly sold or committed transponders under
sales-type and operating leases in 1995.
 
  Net Contributions from (Distributions to) Parent Company. Net contributions
from (distributions to) HE ("Parent Company") were ($109.1) million, $186.7
million and ($1.1) million for the years ended December 31, 1996, 1995 and
1994, respectively.
 
  Net cash flows to Parent Company increased $295.8 million, to a net
distribution of $109.1 million for the year ended December 31, 1996 from a net
contribution of $186.7 million for the year ended December 31, 1995 primarily
as a result of proceeds from the sale and leaseback of Galaxy III-R and
increased cash collections from customers, which more than offset a slight
increase in capital expenditures. Net cash flows from Parent Company increased
$187.8 million, to a net contribution of $186.7 million for the year ended
December 31, 1995, from a net distribution of $1.1 million for the year ended
December 31, 1994. The increase was primarily attributable to a substantial
increase in capital expenditures for new satellites and a decline in operating
cash flows.
 
  Capital Expenditures. Capital expenditures include all additions to
satellites and other property and equipment, but are primarily attributable to
satellite costs. Satellite costs include satellite construction costs, launch
costs, launch insurance and capitalized interest. For the years ended December
31, 1996, 1995 and 1994, capital expenditures were $308.7 million, $280.5
million and $114.7 million, respectively. In 1996, Galaxy's capital
expenditures primarily related to the construction and launch of Galaxy IX in
May 1996 and additional costs incurred in connection with the design and/or
construction of Galaxy VIII-i, Galaxy X and Galaxy XI. In 1995, capital
expenditures primarily related to the construction and launch of Galaxy III-R
in December 1995 and additional costs incurred in connection with the
construction of Galaxy VIII-i, Galaxy IX, Galaxy X and Galaxy XI. In 1994,
capital expenditures primarily related to the construction and launch of
Galaxy I-R in February 1994 and additional costs for Galaxy III-R, Galaxy
VIII-i and Galaxy IX. Galaxy currently has six satellites in various stages of
development for which Galaxy has budgeted future capital expenditures. Such
satellites include Galaxy VIII-i, Galaxy X, Galaxy XI, Galaxy XII, Galaxy
XIII-i and Galaxy XIV-i. The expected total cost of constructing, launching
and insuring each such satellite ranges from approximately $203 million to
approximately $276 million, with the aggregate cost of constructing, launching
and insuring all such satellites expected to be approximately $1,485 million.
Of this aggregate amount, Galaxy had expended approximately $383 million
through December 31, 1996, and expects to fund the remainder through the end
of the year 2000. In addition, Galaxy expects to exercise its Early Buy Out
Options with respect to the leases of transponders on SBS-6 in 1998 for
approximately $152 million, the lease of transponders on Galaxy III-R in 1999
for approximately $170 million and the leases of transponders on Galaxy VII in
1999 for approximately $196 million. Historically, Galaxy has funded capital
expenditures with cash flow from operations of Galaxy's business, proceeds
from the sale and leaseback of satellite transponders and investment by HE.
The Reorganization Agreement requires that, during the period from July 1,
1996 through the Closing Date, cash flows from Galaxy's business and
additional investments by HE be used to fund additional capital expenditures
of approximately $575 million for satellites under construction. At December
31, 1996, approximately $156 million of this funding requirement had been
satisfied. The remaining $419 million of such funding requirement will be
satisfied prior to the Closing Date by (i) HE using Galaxy cash flows and
additional investments by HE to pay approximately $359 million under contracts
for the procurement of long-lead items and/or construction of Galaxy XI,
Galaxy XII, Galaxy XIII-i and Galaxy XIV-i, which agreements Galaxy expects to
enter into prior to
 
                                      170
<PAGE>
 
the Closing Date, and (ii) HE contributing $60 million in cash to New PanAmSat
which funds will be used to pay certain closing costs in connection with
consummating the Reorganization and to pay operating expenses of New PanAmSat
after the Closing Date. Following the Closing Date, Galaxy anticipates that
New PanAmSat will fund the remaining $1,261 million of capital expenditures
required to construct all Galaxy satellites currently under development and
fund New PanAmSat's exercise of the Early Buy Out Options solely from New
PanAmSat's cash on hand and cash flows from the consolidated operations of New
PanAmSat and PanAmSat. See "BUSINESS OF NEW PANAMSAT--Liquidity and Capital
Resources." HE will have no continuing obligation to fund any additional
capital expenditures related to Galaxy's or New PanAmSat's business other than
as described above.
 
  Sales and Leaseback Transactions. Galaxy has sold and leased back
transponders on three separate satellites. In 1991, Galaxy sold all 19
transponders on SBS-6 for $204.7 million and leased the transponders back for
a lease term of 11.2 years. In 1992, Galaxy sold 30 transponders on Galaxy VII
for $314.8 million and leased the transponders back for a lease term of 11
years. In 1996, Galaxy sold 24 transponders on Galaxy III-R for $252.0 million
and leased the transponders back for a lease term of 6.9 years. In connection
with each sale and leaseback transaction, Galaxy recognized a deferred gain in
an amount equal to the difference between the sale proceeds and its cost basis
in the transponders sold, which deferred gain is being amortized on a
straight-line basis over the term of the lease. Periodic lease payments by
Galaxy in connection with the leaseback of transponders are recognized as an
expense on a straight-line basis over the term of the applicable lease, net of
the amortization of the corresponding deferred gain. Lease payments related to
the sale and leaseback of transponders were $62.4 million, $59.9 million and
$62.1 million for the years ended December 31, 1996, 1995 and 1994,
respectively. Under each sale leaseback agreement, Galaxy has the option to
buy back the transponders either at the end of the lease term for fair market
value or at an earlier date and price as stipulated in each respective
agreement. The early buyout terms are SBS-6 in 1998 for $151.7 million, Galaxy
III-R in 1999 for $170.3 million and Galaxy VII in 1999 for $195.9 million,
each of which Galaxy may or may not choose to exercise.
 
ACCOUNTING CHANGE
 
  Effective January 1, 1996, Galaxy adopted SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
This statement established accounting standards for the impairment of long-
lived assets, certain identifiable intangibles, and goodwill related to those
assets to be held and used, and for long-lived assets and certain identifiable
intangibles to be disposed of. Adoption of this statement did not have a
material effect on Galaxy's operating results or financial position.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
  The Unaudited Pro Forma Combined Financial Statements of New PanAmSat as of
and for the year ended December 31, 1996 have been derived from the PanAmSat
Financial Statements and the Galaxy Financial Statements, combined to give
effect to the Merger, the Univisa Contribution (including the Share
Repurchase) and the Asset Contribution, as if such transactions had occurred
at January 1, 1996 for purposes of the Unaudited Pro Forma Combined Statement
of Income and on December 31, 1996 for purposes of the Unaudited Pro Forma
Combined Balance Sheet, applying the purchase method of accounting with Galaxy
as the acquirer of PanAmSat. The unaudited pro forma adjustments are based
upon information set forth in this Proxy Statement/Prospectus and certain
assumptions described below and in the notes to the Unaudited Pro Forma
Combined Financial Statements.
 
  Upon consummation of the Merger, each outstanding share of PAS Ordinary
Common Stock and PAS Class A Common Stock will be converted into the right to
receive, at the election of each holder, either (i) $15 in cash plus one half
( 1/2) share of New PAS Common Stock, (ii) one share of New PAS Common Stock
(subject to proration, as applicable, described below) or (iii) $30 in cash
(subject to proration, as applicable, described below). In connection with the
Univisa Contribution, S Company will receive for each share of PAS Class B
Common Stock indirectly held by Univisa, at S Company's election,
consideration that is equal in amount and form (subject to proration, as
applicable, described below) to the consideration payable on account of each
share of PAS Class A Common Stock and PAS Ordinary Common Stock in the Merger.
The exact amount of cash and/or shares of New PAS Common Stock to be received
by holders of PAS Ordinary Common Stock and PAS Class A Common Stock and S
Company is dependent on, among other things, (a) the stated preferences of
such direct and indirect holders of PAS Common Stock on the Election Forms,
(b) the proration procedures to be applied if the Requested Cash Amount
exceeds the Maximum Cash Amount, and (c) if the Requested Cash Amount is less
than the Cash Cap, whether New PanAmSat, in its sole discretion, limits the
Requested Stock Amount. The Unaudited Pro Forma Combined Financial Statements
assume that all holders of PAS Ordinary Common Stock and PAS Class A Common
Stock receive on account of their shares, and S Company receives, per share of
PAS Class B Common Stock indirectly owned by S Company, the Standard
Consideration of $15 in cash and one half ( 1/2) share of New PAS Common
Stock. See "THE REORGANIZATION AGREEMENT--Terms of the Reorganization" and
"THE UNIVISA CONTRIBUTION AGREEMENT--The Univisa Contribution." The Unaudited
Pro Forma Combined Financial Statements also assume that there will be
149,122,807 shares of New PAS Common Stock outstanding upon consummation of
the Reorganization, which is based on the same assumption regarding payment of
the Standard Consideration and that New PanAmSat will not make an additional
offering of its stock prior to Closing.
 
  The Unaudited Pro Forma Combined Statements of Income do not give effect to
(i) any cost savings that may be realized as a result of the combination of
the two companies or (ii) nonrecurring costs that may be incurred after the
Reorganization is consummated, consisting primarily of expenses related to
relocating employees and modifying facilities. The significance of such
potential cost savings and nonrecurring cost increases will depend on how New
PanAmSat decides in the future to structure its operations. Galaxy and
PanAmSat management believe that the anticipated financial impacts of expected
pension benefits, post-retirement benefits other than pension benefits and
incentive plans on the future operations of New PanAmSat will be comparable to
the impacts included in the PanAmSat Financial Statements and Galaxy Financial
Statements.
 
  These Unaudited Pro Forma Combined Financial Statements should be read in
conjunction with each of the Galaxy and PanAmSat audited financial statements,
including the notes thereto, contained elsewhere herein. The Unaudited Pro
Forma Combined Financial Statements do not purport to present the financial
position or results of operations of New PanAmSat had the transactions and
events assumed therein occurred on the dates specified, nor are they
necessarily indicative of the results of operations that may be achieved in
the future.

                         NOTES TO UNAUDITED PRO FORMA
 
                         COMBINED FINANCIAL STATEMENTS
 
                         (DOLLAR AMOUNTS IN THOUSANDS)
 
  The Unaudited Pro Forma Combined Financial Statements of New PanAmSat give
effect to the Reorganization applying the purchase method of accounting with
Galaxy as the acquirer of PanAmSat, the New Financing and certain related
transactions as if they had occurred at January 1, 1996 for purposes of the
Unaudited Pro Forma Combined Statements of Income and on December 31, 1996 for
purposes of the Unaudited Pro Forma Combined Balance Sheet. The Unaudited Pro
Forma Combined Financial Statements do not purport to present the financial
position or results of operations of New PanAmSat had the transactions and
events assumed therein occurred on the dates specified, nor are they
necessarily indicative of the results of operations that may be achieved in
the future.
 
  The Unaudited Pro Forma Combined Statements of Income do not give effect to
(i) any cost savings that may be realized as a result of the combination of
the two companies nor (ii) nonrecurring costs that may be incurred after the
consummation of the Reorganization, primarily related to employee relocations
and facility modification-related expenses. The significance of such potential
cost savings and nonrecurring cost increases will depend on how New PanAmSat
decides in the future to structure its operations.
 
The following pro forma adjustments were made:
 
(a) To record cash proceeds and tax liability related to the sale of the DTH
    Options concurrent with the Reorganization.
 
(b) To reflect the expected cost of repurchasing PanAmSat's outstanding stock
    options.
 
(c) To record estimated cash required to be contributed by HCI and/or HE
    pursuant to the Reorganization Agreement to partially fund the
    construction and launch costs of various Galaxy spacecraft.
 
(d) To record the increase in intangible assets representing the excess of the
    purchase price over the fair value of the net assets acquired:

   The estimated fair value of the equity portion of the Merger Consideration

   to receive Stock Consideration only (rather than the Standard
   Consideration) and New PanAmSat exercises its option to issue shares of New
   PAS Common Stock in excess of 149,122,807, the borrowings discussed in
   adjustment (i) would be decreased to $225 million with a corresponding
   increase in shareholders' equity to $4,220,991, and interest expense of

                   DESCRIPTION OF NEW PANAMSAT CAPITAL STOCK
 
  The following summary is a description of the capital stock of New PanAmSat
as set forth in the New PanAmSat Certificate of Incorporation and the New
PanAmSat Bylaws that will be in effect prior to consummation of the
Reorganization. Such summary does not purport to be complete and is subject to
and qualified by all of the provisions of the New PanAmSat Certificate of
Incorporation and New PanAmSat Bylaws which are attached hereto as Exhibits F
and G, respectively. All references in the discussion below to the New PanAmSat
Certificate of Incorporation or New PanAmSat Bylaws shall mean such documents
as amended and restated.
 
GENERAL
 
  New PanAmSat is incorporated in the state of Delaware and, pursuant to the
New PanAmSat Certificate of Incorporation, will be authorized to issue
450,000,000 shares of all classes of stock, consisting of 400,000,000 shares of
New PAS Common Stock, par value $.01 per share, and 50,000,000 shares of
Preferred Stock, par value $.01 per share, of New PanAmSat ("New PAS Preferred
Stock"). No shares of New PAS Preferred Stock are outstanding or will be
outstanding immediately after consummation of the Reorganization.
 
COMMON STOCK
 
  Assuming that all holders of PAS Ordinary Common Stock and PAS Class A Common
Stock and S Company elect to receive a combination of cash and shares of New
PAS Common Stock as consideration in the Merger and the Univisa Contribution,
there will be 149,122,807 shares of New PAS Common Stock issued and outstanding
upon consummation of the Reorganization. All such issued and outstanding shares
of New PAS Common Stock will be validly issued, fully paid and nonassessable.
 
  Subject to (i) any preferential rights of any outstanding series of New PAS
Preferred Stock and (ii) any dividend restrictions that may be contained in
credit facilities of New PanAmSat, the holders of New PAS Common Stock are
entitled to receive such dividends, if any, as may be declared from time to
time by the New PanAmSat Board out of funds legally available therefor. It is
not anticipated that dividends will be paid at any time in the foreseeable
future with respect to New PAS Common Stock.
 
  Holders of New PAS Common Stock are entitled to one vote per share on all
matters submitted to a vote of the stockholders of New PanAmSat and do not have
cumulative voting rights. Holders of New PAS Common Stock do not have
preemptive, redemption, conversion or sinking fund rights. In the event of a
liquidation, dissolution or winding up of New PanAmSat, the holders of New PAS
Common Stock are entitled to share equally and ratably in the assets of New
PanAmSat, if any, remaining after the payment of all debts and liabilities of
New PanAmSat and the liquidation preference of any outstanding New PAS
Preferred Stock.
 
  The transfer agent and registrar for New PAS Common Stock will be Boston
EquiServe, L.P. New PanAmSat has obtained conditional approval for the listing
of the New PAS Common Stock on the Nasdaq. It is presently anticipated that the
PAS Ordinary Common Stock, which is currently listed on the Nasdaq under the
symbol "SPOT," will be replaced by the listing of New PAS Common Stock and
trade under the same symbol.
 
NEW PAS PREFERRED STOCK
 
  The New PanAmSat Board is authorized to issue New PAS Preferred Stock in one
or more series with such designations, powers, preferences and rights,
qualifications and limitations or restrictions thereon, including voting
powers, dividend rights, liquidation preferences, redemption rights and
conversion privileges as it determines. There are no plans, agreements or
understandings for the issuance of any shares of New PAS Preferred Stock.
 
REGISTRATION RIGHTS
 
  Pursuant to the terms of the Registration Rights Agreement that will be
entered into at Closing by and among New PanAmSat, HCI, S Company and the
existing holders of PAS Class A Common Stock,
 
                                      177
<PAGE>
 
New PanAmSat will grant to such parties registration rights with respect to
their shares of New PAS Common Stock that may be issued to them in connection
with the Reorganization. With certain limitations, these registration rights
grant such parties the opportunity to (i) demand registration of all or any
portion of their shares of New PAS Common Stock, provided that the aggregate
value of the shares of New PAS Common Stock requested to be registered by such
parties shall be at least $100 million, and (ii) piggyback upon certain
registrations by New PanAmSat of shares of New PAS Common Stock pursuant to a
firm commitment underwritten offering solely for cash for its own account
(other than a registration statement (a) on Form S-8 or any successor forms
thereto, or (b) filed solely in connection with a dividend reinvestment plan
or employee benefit plan of New PanAmSat or its affiliates) or for the account
of any holder of shares of New PAS Common Stock. See "OTHER AGREEMENTS--
Registration Rights Agreement."
 
ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS AND STOCKHOLDER
PROPOSALS
 
  The New PanAmSat Bylaws establish an advance notice procedure for
stockholders to make nominations of candidates for election as directors or
bring other business before an annual meeting of stockholders of New PanAmSat
(the "Stockholder Notice Procedure"). The Stockholder Notice Procedure
provides that (i) only persons who are nominated by, or at the direction of,
the New PanAmSat Board or by a stockholder who has given timely written notice
containing specified information to the Secretary of New PanAmSat prior to the
meeting at which directors are to be elected, will be eligible for election as
directors of New PanAmSat, and (ii) at an annual meeting, only such business
may be conducted as has been properly brought before the meeting by, or at the
direction of, the New PanAmSat Board, or by a stockholder who has given timely
written notice to the Secretary of New PanAmSat of such stockholder's
intention to bring such business before such meeting. In general, for notice
of stockholder nominations or business to be made at an annual meeting to be
timely, such notice must be received by New PanAmSat not less than 60 days nor
more than 90 days prior to the annual meeting.
 
  The purpose of requiring stockholders to give New PanAmSat advance notice of
nominations and other business is to afford the New PanAmSat Board a
meaningful opportunity to consider the qualifications of the proposed nominees
or the advisability of the other proposed business and, to the extent deemed
necessary or desirable by the New PanAmSat Board, to inform stockholders and
make recommendations about such qualifications or business, as well as to
provide a more orderly procedure for conducting meetings of stockholders. The
Stockholder Notice Procedure may have the effect of precluding a contest for
the election of directors or the consideration of stockholder proposals if the
proper procedures are not followed, and of discouraging or deterring a third
party from conducting a solicitation of proxies to elect its own slate of
directors or to approve its own proposal, without regard to whether
consideration of such nominees or proposals might be harmful or beneficial to
New PanAmSat and its stockholders.
 
STOCKHOLDER MEETINGS
 
  The New PanAmSat Certificate of Incorporation does not permit stockholders
of New PanAmSat to act by written consent without a meeting.
 
  The New PanAmSat Bylaws permit the New PanAmSat Board or a committee of the
New PanAmSat Board that has been duly designated by the New PanAmSat Board and
whose power and authority, as expressly provided in a resolution of the New
PanAmSat Board, includes the power to call such a meeting, to call a special
meeting of New PanAmSat stockholders.
 
BOARD OF DIRECTORS
 
  The New PanAmSat Certificate of Incorporation provides for an initial 10
member board of directors. Such number of directors may be changed in
accordance with the terms of the New PanAmSat Bylaws upon the earlier to occur
of certain events set forth in the Stockholder Agreement. As long as the
Stockholder Agreement is in
 
                                      178
<PAGE>
 
effect, HCI will designate all members of the New PanAmSat Board not
designated by the Minority Stockholders; provided that one of the directors
designated by HCI shall be Frederick A. Landman as long as he remains Chief
Executive Officer of New PanAmSat. The Minority Stockholders initially are
entitled to designate two directors of New PanAmSat, one of whom will be
designated by the Class A Holders and one by S Company. See "OTHER
AGREEMENTS--Stockholder Agreement."
 
LIMITATION OF LIABILITY OF DIRECTORS
 
  Pursuant to section 102(b)(7) of the DGCL, the New PanAmSat Certificate of
Incorporation provides that the directors will not be personally liable for
monetary damages to New PanAmSat or its stockholders for breach of fiduciary
duty as a director, except for: (i) breach of the duty of loyalty; (ii) acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law; (iii) liability under Section 174 of the DGCL; or
(iv) any transaction from which the director derives an improper benefit.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The New PanAmSat Certificate of Incorporation obligates New PanAmSat to
indemnify its present and former directors and officers and to pay or
reimburse expenses in advance of the final disposition of a proceeding to the
fullest extent permitted from time to time by the DGCL, provided that the
advancement of expenses will be made only upon receipt of an undertaking by
the director or officer to repay all amounts advanced if it shall ultimately
be determined that the director or officer is not entitled to be indemnified.
The DGCL provides that a director, officer, employee or agent of a Delaware
corporation may be indemnified against liability (other than in an action by
or in the right of the corporation) and expenses including attorneys' fees
incurred by such person in connection with such proceeding, provided such
person acted in good faith and in a manner such person reasonably believed to
be in, or not opposed to, the best interests of the corporation, and, with
respect to any criminal proceeding, had no reason to believe the conduct was
unlawful. For actions or suits brought by or in the name of the corporation,
the DGCL provides that a director, officer, employee or agent of a corporation
may be indemnified against expenses including attorneys' fees incurred by such
person in connection with such proceeding if such person acted in good faith
and in a manner such person reasonably believed to be in, or at least not
opposed to, the best interest of the corporation, except that if such person
is adjudged to be liable to the corporation, such person can be indemnified
for such expenses if and only to the extent that a court determines that
despite the adjudication of liability, in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses as the court shall deem proper. The indemnification provisions of the
New PanAmSat Certificate of Incorporation are mandatory and cannot be amended
without stockholder action.
 
DELAWARE GENERAL CORPORATION LAW SECTION 203
 
  Section 203 of the DGCL provides that, subject to certain exceptions
contained therein, a corporation may not engage in any business combination or
certain other transactions with any "owner of 15% or more of the outstanding
voting stock of the corporation" for a three year period following the date
that such stockholder becomes an interested stockholder unless certain
procedures are followed to safeguard against overreaching or misconduct by
such interested stockholder. In the New PanAmSat Certificate of Incorporation,
New PanAmSat has expressly elected not to be governed by the restrictions of
Section 203 of the DGCL.

                      COMPARISON OF STOCKHOLDERS' RIGHTS
 
  Upon consummation of the Merger and the Univisa Contribution, holders of PAS
Ordinary Common Stock and PAS Class A Common Stock and S Company will become
stockholders of New PanAmSat. Accordingly, their rights will cease to be
defined and governed by the PanAmSat Certificate of Incorporation and PanAmSat
Bylaws and instead will be defined and governed by the New PanAmSat
Certificate of Incorporation and New PanAmSat Bylaws, which both will be
amended and restated prior to consummating the Merger and the Univisa
Contribution. Although PanAmSat and New PanAmSat are governed by the DGCL and
their certificates of incorporation and bylaws have many similarities, certain
provisions of the New PanAmSat Certificate of Incorporation and New PanAmSat
Bylaws, as will be amended and restated, differ in material respects from
those contained in the PanAmSat Certificate of Incorporation and PanAmSat
Bylaws. The following summary, which does not purport to be a complete
statement of the general differences among the rights of the stockholders of
New PanAmSat and the stockholders of PanAmSat, sets forth certain differences
between the New PanAmSat Certificate of Incorporation and New PanAmSat Bylaws
and the PanAmSat Certificate of Incorporation and PanAmSat Bylaws. The
following discussion is qualified by reference to the full text of each of
such documents, which in the case of the New PanAmSat Certificate of
Incorporation and New PanAmSat Bylaws have been attached hereto as Exhibits F
and G, respectively, and are hereby incorporated herein by reference, and in
the case of the PanAmSat Certificate of Incorporation and PanAmSat Bylaws are
hereby incorporated herein by reference. The following discussion assumes that
the New PanAmSat Certificate of Incorporation and New PanAmSat Bylaws have
been amended.
 
VOTING
 
  New PanAmSat. The New PanAmSat Certificate of Incorporation provides for
450,000,000 shares of stock, consisting of 400,000,000 shares of New PAS
Common Stock and 50,000,000 shares of New PAS Preferred Stock. The New
PanAmSat Bylaws provide that each stockholder entitled to vote at any meeting
of stockholders shall be entitled to one vote for each share of stock held by
such stockholder which has voting power upon the matter in question. At all
meetings of stockholders for the election of directors, a plurality of the
votes cast shall be sufficient to elect a director. All other elections and
questions shall, unless otherwise provided by law, the New PanAmSat
Certificate of Incorporation, the New PanAmSat Bylaws or the rules and
regulations of any stock exchange applicable to New PanAmSat, be decided by
the affirmative vote of the majority of the votes present in person or
represented by proxy and entitled to vote thereon. Neither the New PanAmSat
Certificate of Incorporation nor the New PanAmSat Bylaws provide for
supervoting rights.
 
  PanAmSat. PanAmSat's authorized common stock consists of 400,000,000 shares
of PAS Ordinary Common Stock, 100,000,000 shares of PAS Class A Common Stock
and 100,000,000 shares of PAS Class B Common Stock. The shares of PAS Common
Stock presently outstanding are validly issued, fully paid and non-assessable.
The rights of holders of PAS Ordinary Common Stock, PAS Class A Common Stock
and PAS Class B Common Stock are identical except for voting and conversion
rights.
 
  Holders of PAS Ordinary Common Stock are entitled to cast one vote per share
and holders of PAS Class A Common Stock and holders of PAS Class B Common
Stock are entitled to cast fifteen votes per share on all matters submitted to
a vote of common stockholders. The PAS Ordinary Common Stock votes (i) with
the PAS Class A Common Stock for the election of a majority of the directors
of PanAmSat and (ii) with the PAS Class B Common Stock for the election of the
remaining directors of PanAmSat, in each case voting together as a single
class. Also, except as provided in the PanAmSat Certificate of Incorporation
or otherwise required by law, the affirmative vote of (a) the holders of a
majority of the voting power of the PAS Class A Common Stock and the PAS
Ordinary Common Stock, voting together as a single class, and (b) the holders
of a majority of the voting power of the PAS Class B Common Stock and the PAS
Ordinary Common Stock, voting together as a single class, are required to
approve all other matters submitted to a vote of PanAmSat's stockholders.
 
  Approval of (a) a majority of the votes of the outstanding shares of PAS
Class A Common Stock (as long as the outstanding shares of PAS Class A Common
Stock represent at least 5% of the total outstanding shares of
 
                                      180
<PAGE>
 
PAS Common Stock) and a majority of the votes of the outstanding shares of PAS
Class B Common Stock (as long as the outstanding shares of PAS Class B Common
Stock represent at least 5% of the total outstanding shares of PAS Common
Stock), is required in order to take the following actions: (1) material
transactions outside the ordinary course of business and not provided for in
PanAmSat's business plan; (2) material changes to PanAmSat's business plan, or
any material deviation in expenditures, material increases in the level of
indebtedness for borrowed money or incurrence of any guarantees, above the
amounts contemplated by PanAmSat's business plan; (3) subject to certain
exceptions relating to the PAS Preferred Stock, any distributions with respect
to, or redemptions, repurchases, acquisitions or other payments in respect of,
equity interests of PanAmSat; (4) issuances of PAS Ordinary Common Stock or
other equity interests in PanAmSat; (5) any public offering or registration of
securities of PanAmSat; (6) the dissolution, liquidation, termination, merger,
consolidation or reorganization of PanAmSat; (7) certain stockholder or
affiliate transactions; (8) any amendment to the PanAmSat Certificate of
Incorporation or the PanAmSat Bylaws; (9) the creation of any committee of the
PanAmSat Board; or (10) the appointment of the Chief Executive Officer, if a
person other than Rene Anselmo, Frederick A. Landman or Lourdes Saralegui.
 
BOARD OF DIRECTORS
 
  New PanAmSat. The New PanAmSat Certificate of Incorporation provides for an
initial 10 member board of directors. Such number of directors may be changed
in such manner as provided in the New PanAmSat Bylaws upon the earlier to
occur of certain events set forth in the Stockholder Agreement. As long as the
Stockholder Agreement is in effect, HCI will designate all members of the New
PanAmSat Board not designated by Minority Stockholders; provided that one of
the directors designated by HCI shall be Frederick A. Landman as long as he
remains Chief Executive Officer of New PanAmSat. The Minority Stockholders
initially are entitled to designate two directors of New PanAmSat, one of whom
will be designated by the Class A Holders and one by S Company. See "OTHER
AGREEMENTS--Stockholder Agreement." Immediately after the Closing Date, it is
anticipated that New PanAmSat will have only nine directors if S Company has
not yet appointed a director. Such seat will remain vacant until S Company
appoints a director. See "MANAGEMENT OF NEW PANAMSAT--Board of Directors."
 
  PanAmSat. The PanAmSat Certificate of Incorporation provides for an initial
five member board of directors and such number of directors may be changed
from time to time upon the affirmative vote of at least a majority of the
votes of the outstanding shares of PAS Class A Common Stock and the
outstanding shares of PAS Class B Common Stock, each voting as separate
classes. The holders of PAS Class A Common Stock and the holders of PAS
Ordinary Common Stock, voting together as a single class, are entitled to
elect at least a majority of the PanAmSat Board, and the holders of PAS Class
B Common Stock and the holders of PAS Ordinary Common Stock, voting together
as a single class, are entitled to elect the remaining directors of PanAmSat.
 
LIMITATION OF LIABILITY OF DIRECTORS
 
  The DGCL provides that a corporation may include in its certificate of
incorporation a provision which limits or eliminates the personal liability of
a director to the corporation and/or its stockholders for monetary damages for
such person's conduct as a director, provided that such provision may not so
limit a director's liability (i) for breach of his or her duty of loyalty to
the corporation or its stockholders; (ii) for acts or omissions not in good
faith or involving intentional misconduct or a knowing violation of law; (iii)
for unlawful payments of dividends, certain stock repurchases or redemptions;
or (iv) for any transaction from which the director derived an improper
personal benefit. Both New PanAmSat and PanAmSat provide in their respective
certificates of incorporation for the limitation on liability of directors to
the fullest extent allowed under the DGCL.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS; ADVANCEMENT OF EXPENSES AND
INSURANCE
 
  The DGCL provides that a director, officer, employee or agent of a Delaware
corporation may be indemnified against liability (other than in an action by
or in the right of the corporation) and expenses (including attorneys' fees)
incurred by such person in connection with such proceeding, provided such
person acted in good
 
                                      181
<PAGE>
 
faith and in a manner such person reasonably believed to be in, or not opposed
to, the best interests of the corporation, and, with respect to any criminal
proceeding, had no reason to believe the conduct was unlawful. For actions or
suits brought by or in the name of the corporation, the DGCL provides that a
director, officer, employee or agent of a corporation may be indemnified
against expenses (including attorneys' fees) incurred by such person in
connection with such proceeding if such person acted in good faith and in a
manner such person reasonably believed to be in, or not opposed to, the best
interest of the corporation, except that if such person is adjudged to be
liable to the corporation, such person can be indemnified if and only to the
extent that a court determines that despite the adjudication of liability, in
view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses as the court shall deem
proper. Expenses incurred by an officer or director in defending an action,
suit or proceeding may be advanced prior to the final disposition of such
action, suit or proceeding upon receipt of an undertaking by or on behalf of
such director or officer to repay such amount if it is ultimately determined
he is not entitled to indemnification. The respective certificates of
incorporation of PanAmSat and New PanAmSat provide for indemnification of
directors and officers and advancement of expenses to the fullest extent
permitted under the DGCL. The DGCL also permits Delaware corporations to
purchase and maintain insurance on behalf of any person who is or was a
director or officer of the corporation. The PanAmSat Bylaws permit PanAmSat to
purchase liability insurance for its officers and directors. The
Reorganization Agreement requires that, subject to certain exceptions, New
PanAmSat purchase liability insurance for its officers and directors for a
period of five years following the Closing Date.
 
STOCKHOLDER NOMINATIONS OF CANDIDATES FOR THE BOARD OF DIRECTORS AND OTHER
PROPOSALS
 
  New PanAmSat. The New PanAmSat Bylaws establish an advance notice procedure
for stockholders to nominate candidates for election as directors or bring
other business before an annual meeting of stockholders of New PanAmSat. Such
stockholder notice procedure provides that (i) only persons who are nominated
(a) pursuant to New PanAmSat's notice of meeting, (b) by, or at the direction
of, the New PanAmSat Board or (c) by a stockholder who has given timely
written notice containing specified information to the Secretary of New
PanAmSat prior to the meeting at which directors are to be elected, will be
eligible for election as directors of New PanAmSat, and (ii) at an annual
meeting only such business may be conducted as has been properly brought
before the meeting (a) pursuant to New PanAmSat's notice of meeting, (b) by,
or at the direction of, the New PanAmSat Board or (c) by a stockholder who has
given timely written notice containing specified information to the Secretary
of New PanAmSat of such stockholder's intention to bring such business before
such meeting. In general, for notice of stockholder nominations or business to
be made at an annual meeting to be timely, such notice must be received by New
PanAmSat not less than 60 days nor more than 90 days prior to the annual
meeting.
 
  The purpose of requiring stockholders to give New PanAmSat advance notice of
nominations and other business is to afford the New PanAmSat Board a
meaningful opportunity to consider the qualifications of the proposed nominees
or the advisability of the other proposed business and, to the extent deemed
necessary or desirable by the New PanAmSat Board, to inform stockholders and
make recommendations about such qualifications or business, as well as to
provide a more orderly procedure for conducting meetings of stockholders. The
Stockholder Notice Procedures may have the effect of precluding a contest for
the election of directors or the consideration of stockholder proposals if the
proper procedures are not followed and of discouraging or deterring a third
party from conducting a solicitation of proxies to elect its own slate of
directors or to approve its own proposal, without regard to whether
consideration of such nominees or proposals might be harmful or beneficial to
New PanAmSat and its stockholders.
 
  PanAmSat. PanAmSat has no advance notice requirement with regard to
stockholder nominations for the PamAmSat Board or for other stockholder
proposals.
 
AMENDMENT OR REPEAL OF THE CERTIFICATE OF INCORPORATION AND BYLAWS
 
  The DGCL provides that (i) a corporation's certificate of incorporation may
be amended only by a vote of the stockholders of such corporation and (ii) the
bylaws of a corporation may be amended by a vote of its stockholders or, if
provided in its certificate of incorporation, by the board of directors of
such corporation.
 
                                      182
<PAGE>
 
  New PanAmSat. The New PanAmSat Certificate of Incorporation provides for the
amendment, alteration, change or repeal of any provision contained in the New
PanAmSat Certificate of Incorporation, as permitted under Delaware law and
expressly authorizes the New PanAmSat Board to make, alter and repeal the New
PanAmSat Bylaws.
 
  PanAmSat. The PanAmSat Certificate of Incorporation requires the approval by
a majority of the votes of the outstanding shares of both PAS Class A Common
Stock and PAS Ordinary Common Stock, voting together as a single class, as
well as a majority of the votes of the outstanding shares of both PAS Class B
Common Stock and PAS Ordinary Common Stock, voting together as a single class,
to amend the PanAmSat Certificate of Incorporation or PanAmSat Bylaws.
Additionally, as long as the outstanding shares of PAS Class A Common Stock
and/or PAS Class B Common Stock represent at least 5% of the number of
outstanding shares of PAS Common Stock, a majority of the votes of each such
outstanding class must approve any proposed amendment to, or repeal of, the
PanAmSat Certificate of Incorporation or PanAmSat Bylaws.
 
PREEMPTIVE RIGHTS
 
  The DGCL provides that no stockholder of a Delaware corporation shall have
any preemptive right to subscribe to an additional issue of stock or to any
security convertible into such stock unless such right is expressly granted in
the certificate of incorporation.
 
  New PanAmSat. The New PanAmSat Certificate of Incorporation and New PanAmSat
Bylaws do not provide for preemptive rights.
 
  PanAmSat. Holders of PAS Class A Common Stock and holders of PAS Class B
Common Stock shall be entitled to purchase, in each instance, at the net price
per share received by PanAmSat for the PAS Ordinary Common Stock, additional
shares of PAS Class A Common Stock or PAS Class B Common Stock, respectively,
if and to the extent necessary to maintain 51% of the total voting power of
PAS Class A Common Stock and the PAS Ordinary Common Stock, voting together as
a single class, in the case of the PAS Class A Common Stock, and 51% of the
total voting power of PAS Class B Common Stock and the PAS Ordinary Common
Stock, voting together as a single class, in the case of the PAS Class B
Common Stock.
 
  PanAmSat may not issue any additional shares of PAS Class A Common Stock or
PAS Class B Common Stock without the approval of the holders of a majority of
the shares of PAS Ordinary Common Stock, except that PanAmSat may issue
additional shares of PAS Class A Common Stock and PAS Class B Common Stock in
connection with stock splits, stock dividends and other distributions and as
otherwise permitted by the Certificate of Incorporation. The holders of PAS
Ordinary Common Stock, PAS Class A Common Stock and PAS Class B Common Stock
are not entitled to preemptive rights or similar rights, except as described
as above.
 
LIQUIDATION RIGHTS
 
  Generally, under the DGCL, a corporation may create one or more classes or
series of stock which classes or series may have such preferences as shall be
stated and expressed in the certificate of incorporation or in the resolution
adopted by the board of directors providing for the issue of such stock
pursuant to authority expressly vested in it by the provisions of its
certificate of incorporation. These preferences may include a priority on the
distribution of assets in liquidation.
 
  New PanAmSat.  PanAmSat and Galaxy currently anticipate that, following the
Reorganization, New PanAmSat will have only New PAS Common Stock issued and
outstanding. Should New PanAmSat elect to issue New PAS Preferred Stock, the
New PanAmSat Board may determine what preference such New PAS Preferred Stock
shall have in the distribution of assets in liquidation. The ability of the
New PanAmSat Board to designate and determine the rights of shares of New PAS
Preferred Stock may adversely affect the rights of the holders of New PAS
Common Stock by allowing the New PanAmSat Board to entrench itself and make it
more difficult for a third party to acquire a majority of the outstanding
voting stock of New PanAmSat.
 
 
                                      183
<PAGE>
 
  PanAmSat. Upon voluntary or involuntary liquidation, dissolution or winding-
up of the affairs of PanAmSat, the holders of PAS Preferred Stock shall be
entitled to receive the full amount to which they are entitled pursuant to the
PanAmSat Certificate of Incorporation and any resolutions that may be adopted
from time to time. As of April 2, 1997, there were 20,000,000 shares of PAS
Preferred Stock authorized and 341,843.2640 shares of PAS Preferred Stock
outstanding. The shares of PAS Preferred Stock outstanding at December 31,
1996 had an aggregate liquidation preference of $329 million. Upon
dissolution, holders of PAS Class A Common Stock, PAS Class B Common Stock and
PAS Ordinary Common Stock shall be entitled to share equally in the assets of
PanAmSat remaining after satisfying such liquidation preference.
 
DELAWARE GENERAL CORPORATION LAW SECTION 203
 
  Section 203 of the DGCL provides that, subject to certain exceptions
provided therein, a corporation shall not engage in any business combination
or certain other transactions with any "owner of 15% or more of the
outstanding voting stock of the corporation" for a three year period following
the date that such stockholder becomes an interested stockholder unless
certain procedures are followed to safeguard against overreaching or
misconduct by such interested stockholder. In both the New PanAmSat
Certificate of Incorporation and the PanAmSat Certificate of Incorporation,
each of New PanAmSat and PanAmSat has expressly elected not to be governed by
the restrictions of Section 203 of the DGCL.

  In the future, the New PanAmSat Board will rely on its Compensation
Committee, which will be composed of non-employee directors, to recommend the
form and amount of compensation to be paid to New PanAmSat's executive
officers. It is anticipated that the Compensation Committee will generally
adhere to compensation policies which reflect the belief that (i) New PanAmSat
must attract and retain individuals of outstanding ability and motivate and
reward such individuals for sustained performance, (ii) a substantial portion
of an executive's compensation should be at risk based on the executive's
performance and that of New PanAmSat, and (iii) within these parameters,
levels of compensation should generally be in line with that offered by
comparable corporations. On an ongoing basis, the type and amount of
compensation to be paid by New PanAmSat to its officers will be entirely
discretionary and within the subjective judgment of the Compensation
Committee.
 
EMPLOYMENT AGREEMENTS
 
  It is anticipated that Frederick A. Landman will serve as President and

PanAmSat.

Closing Date. The directorship to be filled by S Company will remain vacant
until S Company appoints a director. See "OTHER AGREEMENTS--Stockholder
Agreement."
 
DIRECTOR COMPENSATION; COMMITTEES
 
  New PanAmSat expects to pay each of its non-employee directors a fee of
$16,000 per year for services as a director plus $1,000 to $1,500 for
attendance at each meeting of the New PanAmSat Board. In addition, New
PanAmSat shall reimburse the directors for travel expenses incurred in
connection with their duties as directors of New PanAmSat and the non-employee
directors will be eligible to participate in the 1997 Stock Plan (as defined
below). Patrick J. Costello will not receive a director's fee during the time
that he is serving as a transitional consultant to New PanAmSat.
 
  At the Effective Time, the New PanAmSat Board is expected to have (i) a
Disinterested Directors Committee, (ii) an Audit Committee and (iii) a
Compensation Committee.
 
 
                                      188
<PAGE>
 
  Disinterested Directors Committee. The Disinterested Directors Committee
will be composed of the directors of New PanAmSat that are not existing or
retired employees of New PanAmSat or any of its "affiliates" (as defined in
Rule 12b-2 under the Securities and Exchange Act of 1934, as amended). Its
functions will be to review and recommend (in accordance with Section 7.23 of
the Reorganization Agreement and Section 2(c) of the Stockholder Agreement)
action on tender offers to acquire outstanding equity interests of New
PanAmSat for a period of five years after the Closing.
 
  Audit Committee. The Audit Committee will be composed of three or more
directors of New PanAmSat, none of whom is an officer or employee of New
PanAmSat. It will have the powers and responsibilities designated to it by the
New PanAmSat Board from time to time. Its functions will be to make
recommendations
annually concerning the appointment of a firm of independent accountants to
audit New PanAmSat financial statements; review the arrangements for and scope
of the audit by independent accountants; consider the adequacy of the system
of New PanAmSat internal accounting controls and review any proposed
corrective actions.
 
  Compensation Committee. The Compensation Committee will be composed of three
or more directors of New PanAmSat, each of whom shall satisfy the "non-
employee director" requirements of Rule 16b-3 of the Exchange Act and the
"outside director" requirements of Section 162(m) of the Code. It will have
the following powers and responsibilities: to review and recommend
compensation levels, bonus amounts, stock option grants and benefit plans; to
request and review reports from New PanAmSat management on the scope,
competence, performance and motivation of management employees; to develop,
review and recommend bonus, stock option and similar incentive plans or
programs and retirement and welfare plans or programs; to interpret bonus,
stock option and similar incentive plans; and to develop, review and recommend
changes of major benefit programs.

                NEW PANAMSAT EMPLOYEE BENEFIT AND OPTION PLANS
 
EMPLOYEE BENEFIT PLANS
 
  New PanAmSat will offer its employees a comprehensive flexible benefits
package that will include the New PanAmSat Savings Plan (the "401(k) Plan"), a
health plan offering various medical, dental and vision coverage options,
several life, disability and accident insurance programs and a paid time-off
plan. The 401(k) Plan will be a defined contribution plan intended to qualify
under Section 401(a) of the Code that will include a cash or deferred
arrangement intended to qualify under Section 401(k) of the Code. Any employee
who completes one half year of service and attains age 21 will be eligible to
participate in the 401(k) Plan. Each participant will be able to elect to make
elective deferral contributions from 1% up to 15% of the participant's
compensation subject to a limit ($9,500 for 1997) which is prescribed by the
Code and adjusted for inflation periodically. The employer will make 100%
matching contributions with respect to each participant's elective deferrals
in the form of New PAS Common Stock, up to a maximum of 4% of the
participant's compensation. The employer may also make discretionary profit-
sharing contributions under the plan. Elective deferral and employer matching
contributions will be fully vested at all times. Any employer discretionary
profit-sharing contributions will be subject to a 6-year vesting schedule
under which the participant will become 20% vested after 2 years of service,
40% vested after 3 years of service, and so on, until the participant becomes
100% vested after 6 years of service. Upon retirement or other termination of
employment, a participant's account balance will be distributable to the
participant (or to the participant's beneficiary) in accordance with the
participant's election. Amounts will be distributed either in a lump sum or in
installment payments. It is anticipated that distributions may be made
available to participants during their employment in order to satisfy an
immediate and heavy financial need which cannot be reasonably satisfied from
other sources. It is also anticipated that the 401(k) Plan will permit
participants to borrow a portion of their vested account balances pursuant to
a uniform and non-discriminatory loan program. See "THE REORGANIZATION
AGREEMENT--Certain Benefits Matters."
 
  Current HCI employees who are participants in HE's defined benefit pension
plan (the "HE Pension Plan") and who will become employees of New PanAmSat in
connection with the Reorganization will generally receive a lump-sum
distribution of their accrued benefits in the HE Pension Plan.
 
  New PanAmSat employees will generally be eligible to receive "flex credits"
("Flex Credits") equal to 2% of the employee's annual salary. These Flex
Credits may be used to purchase health and insurance benefits offered under
the New PanAmSat benefits package and, to the extent not utilized for such
purposes, may be invested in the New PanAmSat Savings Plan or taken by the
employee as taxable income.
 
LONG-TERM STOCK INCENTIVE PLAN
 
  It is anticipated that the New PanAmSat Board will adopt, subject to
approval by the stockholders of New PanAmSat, the Long-Term Stock Incentive
Plan Established in 1997 (the "1997 Stock Plan"). The 1997 Stock Plan is
intended to satisfy specific requirements of Section 162(m) of the Code
(discussed below) for grants of stock options (and may be amended, to the
extent necessary, to satisfy such requirements with respect to restricted
stock, performance units and performance shares) and Rule 16b-3 under the
Exchange Act. The 1997 Stock Plan is designed to provide long-term incentives
and rewards to employees of New PanAmSat, to assist New PanAmSat in attracting
and retaining employees with experience and/or ability on a basis competitive
with industry practices and to associate the interest of such employees with
those of the New PanAmSat stockholders. The 1997 Stock Plan will provide for
the issuance of up to 7,456,140 shares of New PAS Common Stock, approximately
5% of the outstanding shares of New PAS Common Stock at the Closing, pursuant
to the grant or exercise of stock options (including ISOs), alternate
appreciation rights, restricted stock, performance units and performance
shares. No single participant may be granted awards pursuant to the 1997 Stock
Plan covering in excess of 2,000,000 shares of New PAS Common Stock. Awards
may be granted to officers, other employees, directors and independent
contractors, as described below.
 
  Administration. The 1997 Stock Plan will be administered by the Compensation
Committee of the New PanAmSat Board. Shares available under the 1997 Stock
Plan can be allocated among the various types of
 
                                      190
<PAGE>
 
awards and among the participants as the Compensation Committee deems
appropriate. Awards may be granted for such terms as the Compensation
Committee may determine, except that the term of an ISO may not exceed ten
years from its date of grant. No awards outstanding on the termination date of
the 1997 Stock Plan shall be affected or impaired by such termination. Awards
will not be transferable, except by will and the laws of descent and
distribution, unless otherwise permitted by the Compensation Committee. The
Compensation Committee will have broad authority to set the terms and
conditions of individual agreements with participants, other than with respect
to the participants' exercise rights upon termination of employment (or
services, in the case of a non-employee award recipient) by reason of death,
disability, retirement, termination by New PanAmSat without "cause" and upon
termination for any other reason. See "Exercisability of Awards" below.
 
  Exercisability of Awards. Upon the death or disability of a recipient of an
award under the 1997 Stock Plan during the recipient's employment (or
performance of services in the case of a non-employee) the recipient may
exercise any award which is otherwise exercisable on the date of death or
disability within one year of termination due to death or disability. In the
case of death, the award may be exercised by the recipient's estate or by a
person who acquires the right to exercise the award by death of the recipient.
In the case of disability, the award may be exercised by the recipient or, if
the recipient is incapacitated, by a guardian or legal representative. If the
employment (or the performance of services, in the case of a non-employee) of
an award recipient terminates by reason of retirement or by reason of
termination by New PanAmSat without "cause" (as defined in the 1997 Stock
Plan), the recipient may exercise any award which was exercisable on the date
of termination of employment (or services, in the case of a non-employee)
within three months of such a termination. It has not yet been determined how
long this period will be extended upon disability or retirement. Upon
termination of the employment (or services, in the case of a non-employee) of
an award recipient for any other reason, any award granted to the individual
will terminate. Any award granted which is not exercised within the
permissible time following termination of employment (or services in the case
of non-employees) will terminate.
 
  Method of Payment for Stock Options. Upon exercise of any option granted
under the 1997 Stock Plan, the optionee must pay to New PanAmSat in full, the
exercise price for such shares set by the Compensation Committee on the date
of grant and any applicable withholding taxes either in cash, previously owned
New PAS Common Stock or a combination of cash and previously owned New PAS
Common Stock. In addition, each option agreement must permit the optionee to
pay the exercise price through a cashless exercise program established by New
PanAmSat or the Compensation Committee with a broker.
 
  Types of Awards. As indicated above, several types of stock-related grants
will be available under the 1997 Stock Plan. A summary of these grants is set
forth below:
 
  .  Stock Options. The 1997 Stock Plan authorizes the Compensation Committee
     to grant options to purchase New PAS Common Stock at an exercise price
     (the "option price") equal to the fair market value of the New PAS
     Common Stock at the date of such grant (110% of the fair market value in
     the case of ISOs granted to ten (10%) percent shareholders of New PAS
     Common Stock). As noted above, options may be granted either as ISOs or
     nonqualified options. The principal difference between ISOs and
     nonqualified options is their tax treatment. See "Federal Income Tax
     Consequences," below.
 
  .  Alternate Appreciation Rights. The 1997 Stock Plan authorizes the
     Compensation Committee to grant alternate appreciation rights in
     conjunction with the grant of options, whether ISOs or nonqualified
     options. An alternate appreciation right will permit the optionee to be
     paid the appreciation on the shares underlying the option in lieu of
     exercising the option. Upon exercise of an alternate appreciation right,
     the participant will receive an amount, payable in New PAS Common Stock,
     equal to the difference between the fair market value of the New PAS
     Common Stock as of the exercise date and the exercise price of the
     option related to the alternate appreciation right.
 
  .  Restricted Stock. The 1997 Stock Plan authorizes the Compensation
     Committee to grant restricted stock to individuals with such
     restrictions as the Compensation Committee may designate.
 
 
                                      191
<PAGE>
 
  .  Performance Units. The 1997 Stock Plan authorizes the Compensation
     Committee to grant performance units to individuals based on performance
     criteria established by the Compensation Committee.
 
  .  Performance Shares. The 1997 Stock Plan authorizes the Compensation
     Committee to grant performance shares to individuals based on
     performance criteria established by the Compensation Committee.
 
  Amendment and Discontinuance. The 1997 Stock Plan may be amended, altered or
discontinued by the Compensation Committee, but no amendment, alteration or
discontinuance may be made which would (i) impair the rights of a participant
under an award previously granted to him without the participant's consent,
except such an amendment made to comply with changes in law or stock exchange
rules, (ii) increase the maximum number of shares of New PAS Common Stock
which may be issued under the 1997 Stock Plan to all participants or to any
one participant (other than increases resulting from "Changes in
Capitalization" described below), (iii) extend the period during which any
award may be granted or exercised, or (iv) extend the term of the 1997 Stock
Plan, without shareholder approval.
 
  Changes in Capitalization. The 1997 Stock Plan provides that, in the event
of any change in the outstanding New PAS Common Stock by reason of a stock
dividend or distribution, recapitalization, merger, consolidation, split-up,
combination, exchange of shares or the like, the Compensation Committee may
appropriately adjust the number of shares of New PAS Common Stock which may be
issued under the 1997 Stock Plan, the maximum number of shares in respect of
which options or other awards may be granted to any individual during its
term, the number of shares of New PAS Common Stock subject to options
previously granted, the exercise price of options previously granted, and any
and all other matters deemed appropriate by the Compensation Committee.
 
  Federal Income Tax Consequences. The following discussion is intended only
as a brief summary of the federal income tax rules relevant to stock options,
alternate appreciation rights, restricted stock, performance units and
performance shares. The laws governing tax aspects of awards are highly
technical and subject to change.
 
  .  Nonqualified Options and Alternative Appreciation Rights. Upon the grant
     of a nonqualified option (with or without an alternate appreciation
     right), the optionee will not recognize any taxable income and New
     PanAmSat will not be entitled to a deduction. Upon the exercise of such
     an option or an alternate appreciation right, the excess of the fair
     market value of the shares acquired on the exercise of the option over
     the option price (the "spread"), or the consideration paid to the
     optionee upon exercise of the alternate appreciation right, will
     constitute compensation taxable to the optionee as ordinary income. In
     determining the amount of the spread or the amount of consideration paid
     to the optionee, the fair market value of the stock on the date of
     exercise is used, except that in the case of an optionee subject to
     Section 16(b) of the Exchange Act, such ordinary income will not be
     realized until the end of such period, if any, during which a sale of
     the shares could subject the optionee to suit under Section 16(b), and
     will be measured by the fair market value of the stock at that time,
     unless such optionee elects under Section 83(b) of the Code to realize
     ordinary income at the time of exercise, measured by the fair market
     value of the stock at that time. The precise application of the
     foregoing deferral of income rule under applicable rules adopted by the
     Commission under Section 16 of the Exchange Act is not entirely clear.
     It appears likely, however, that realization of income will no longer be
     deferred, at least unless the optionee has other matching purchases of
     stock during the six-month period prior to the exercise of the option,
     and perhaps not even then. New PanAmSat, in computing its federal income
     tax, will generally be entitled to a deduction in an amount equal to the
     compensation taxable to the optionee.
 
  .  Incentive Stock Options. An optionee who is granted an ISO would not
     recognize taxable income either on the date of grant or on the date of
     its timely exercise, although the exercise of an ISO would be an item of
     tax preference income potentially subject to the alternative minimum
     tax. Upon
 
                                      192
<PAGE>
 
     disposition of the New PAS Common Stock acquired upon exercise of an
     ISO, capital gain or loss would be recognized in an amount equal to the
     difference between the sales price and the option exercise price,
     provided the participant has not disposed of the New PAS Common Stock
     within two years of the date of grant and within one year from the date
     of exercise. When a participant exercises an ISO, New PanAmSat would not
     generally be entitled to a tax deduction. However, if the participant
     disposes of stock acquired through exercise of such an option before
     meeting the required holding period, the participant must generally
     recognize ordinary income in the amount of the difference between the
     option exercise price and the fair market value of the New PAS Common
     Stock on the date of exercise, and New PanAmSat would be entitled to a
     deduction equal to the amount of ordinary income recognized by the
     participant. If the holder of an ISO pays the exercise price, in full or
     in part, with previously acquired shares of New PAS Common Stock, no
     capital gain or loss is recognized upon the surrender of such previously
     acquired shares.
 
  .  Restricted Stock, Performance Units and Performance Shares. The federal
     income taxation of individuals who are awarded restricted stock,
     performance units or performance shares will depend upon the
     restrictions and limitations imposed on such awards by the Compensation
     Committee. During any periods that the awards are subject to substantial
     limitations or restrictions (for example, restricted shares which are
     awarded subject to a substantial risk of forfeiture based on the
     performance of services or the attainment of performance goals), the
     individual receiving the award will not be subject to current federal
     income taxation. Concomitantly, during the period when the awards are
     subject to substantial limitations or restrictions, New PanAmSat will
     not be entitled to a compensation deduction. However, because the
     specific limitations and restrictions applicable to these awards are
     determined solely by the Compensation Committee and are not specified in
     the terms of the 1997 Stock Plan, no specific discussion of their
     federal income tax consequences is possible.
 
  The only benefits determinable as of the date of this Proxy
Statement/Prospectus that will be received under the 1997 Stock Plan are stock
options to purchase New PAS Common Stock. It is anticipated that Mr. Landman,
Mr. Brown, Ms. Saralegui, Mr. Heintz, Mr. Cuminale and Mr. Bednarek will
receive grants of 93,750, 31,250, 31,250, 25,000, 12,500 and 12,815 shares,
respectively. Such options are anticipated to be granted on the Closing Date.
It is anticipated that such options will vest at a rate of 33 1/3% per year
over three years commencing on the date of the grant.
 
ANNUAL INCENTIVE PLAN
 
  New PanAmSat intends to establish the Annual Incentive Plan (the "Annual
Incentive Plan"), effective as of January 1, 1997, subject to approval by New
PanAmSat's stockholders. The Annual Incentive Plan is intended to satisfy
specific requirements of Section 162(m) of the Code with respect to the
payment of performance-based awards. The Annual Incentive Plan will, in its
current draft form, provide for the payment to eligible participants of annual
incentive cash awards. The annual terms of the plan will correspond to New
PanAmSat's fiscal year, running from January 1 through December 31 (the "Plan
Year"), with the initial Plan Year to commence on January 1, 1997.
 
  To be eligible to participate in the Annual Incentive Plan, an individual
must be: (i) an employee of New PanAmSat and (ii) recommended by the Chief
Executive Officer and considered and approved by the Compensation Committee
for participation in the Annual Incentive Plan.
 
  The Annual Incentive Plan will provide a target bonus for all participants
that is tied to pre-established corporate financial performance measures and
goals designed to promote shareholder value creation. The performance period
with respect to which awards may be payable under the Annual Incentive Plan
will generally be the Plan Year, provided that the Committee has the authority
and discretion to designate different performance periods under the Annual
Incentive Plan.
 
  Within the first ninety days of each Plan Year, the Compensation Committee
will approve or establish in writing one or more performance goals or
measures, a specific target objective or objectives with respect to such
 
                                      193
<PAGE>
 
performance goals or measures, and an objective formula or method for
compiling the amount of incentive compensation payable to each participant
under the Annual Incentive Plan if the goals are attained.
 
  As soon as practicable after the end of the Plan Year, the Compensation
Committee will certify in writing the extent to which participants have
achieved the performance goals and standards for the Plan Year, including the
specific target objectives and the satisfaction of any other material terms of
the incentive awards. The Compensation Committee will then calculate the
amount of each participant's incentive award for the relevant period.
 
  Approved incentive awards will be payable by New PanAmSat in cash to each
participant, or to his or her estate in the case of death, as soon as
practicable after the end of each performance period and after the
Compensation Committee has certified in writing that the specified goals were
achieved.
 
  An incentive award that would be payable but for the fact that the
participant was not employed by New PanAmSat on the last day of the
performance period shall either be prorated or not paid, in accordance with
the rules and regulations adopted by the Compensation Committee for the
administration of the Annual Incentive Plan. In the event that a participant's
employment with New PanAmSat terminates voluntarily or for cause, no portion
of any target award will be paid. If termination is involuntary or on account
of death, disability or retirement, a pro rata award will be paid within a
reasonable period of time after the end of the fiscal year in which the
termination occurs.
 
  The maximum amount of compensation payable under the Annual Incentive Plan
during any performance period is $1 million for any participant in the Annual
Incentive Plan.
 
DEFERRED COMPENSATION PLAN
 
  New PanAmSat anticipates that it will implement a plan that will allow its
executive officers and certain of its employees to defer compensation. The
details of such plan have not yet been finalized by New PanAmSat.

Common Stock or PAS Ordinary Common Stock, (ii) each of the directors of
PanAmSat, (iii) each of PanAmSat's Chief Executive Officer and the four other
most highly compensated executive officers of PanAmSat for the fiscal year

                             CERTAIN TRANSACTIONS
 
PANAMSAT
 
  PanAmSat has various satellite service agreements with Televisa and its
affiliates. Pursuant to these agreements, PanAmSat received payments in the
nine months ended September 30, 1996 aggregating $6.7 million, relating to
satellite services provided by the PAS-1 and PAS-3 satellites. At September
30, 1996, approximately $195 million of PanAmSat's expected future cash
payments from the PAS-1 and PAS-3 satellites were represented by long-term
arrangements with Televisa and its affiliates.
 
  PanAmSat previously was committed to purchase several million dollars' worth
of equipment in connection with a DTH joint venture to be formed by PanAmSat
and Televisa pursuant to the Original MOU. This commitment was canceled by
PanAmSat pursuant to the Revised MOU and any costs associated with this
termination have been reimbursed by Televisa under a separate indemnification
agreement. See "THE DTH SALE."
 
  In November 1995, PanAmSat announced that it would serve as a satellite
service provider for the Latin America DTH service to be offered by Globo,
Televisa, News Corp. and TCI. PanAmSat signed the 1996 Letter Agreement to
provide service to the Latin America JVs on 48 transponders ultimately on PAS-
5 and PAS-6, with temporary service on PAS-3 pending the commencement of
service on PAS-6. See "BUSINESS OF PANAMSAT--DTH Strategy." Under the 1996
Letter Agreement, Globo, Televisa and News Corp. have agreed to proportionally
guarantee 100% of the fees for transponder services to the Latin America JVs.
These guarantee obligations may be assigned to TCI and, with PanAmSat's prior
written consent, to new equity participants in the Latin America JVs. PanAmSat
will receive minimum service fees equivalent to PanAmSat's estimate of the
cost per transponder to PanAmSat of designing, launching, operating and
insuring each satellite for transponders used by the Latin America JVs.
PanAmSat also will receive additional revenue based on subscriber revenues of
the Latin America JVs above a certain threshold, except that the transponders
that will be used by the Latin America JV operating in Brazil will be charged
on a fixed fee basis. The 1996 Letter Agreement also contemplates that three
separate full-scale transponder agreements will be entered into for the
regions of (i) Brazil, (ii) Mexico and (iii) Latin America (not including
Brazil and Mexico) and, with respect to Spanish and/or Portuguese language
programming, the United States, Canada and Puerto Rico. The Brazil Transponder
Agreement has been entered into with respect to 12 transponders on PAS-6 for
Brazil, while the 1996 Letter Agreement remains in force as to the remaining
24 transponders on PAS-6 and 12 transponders on PAS-5 for the other regions.
Execution of full-scale transponder agreements for the other two regions is
subject to negotiation and no assurance can be given that such full-scale
transponder agreements will be executed. The 1996 Letter Agreement and the
Brazil Transponder Agreement provide for minimum payments over their
respective terms of approximately $1.3 billion, depending upon the actual
useful life of the satellites in question, their predicted performance and
their in-service dates. On cost-based transponders, PanAmSat will also be
eligible to receive revenue sharing from the Latin America JVs.
 
  Pursuant to the Original MOU, PanAmSat and Televisa intended to establish
and operate a Ku-band digital DTH satellite broadcasting business serving
Latin America. The Original MOU was terminated and superseded by the Revised
MOU, except with respect to the indemnification obligations described above.
Pursuant to  the Revised MOU and certain oral agreements in principle with
Televisa, PanAmSat has DTH Options to purchase equity in certain of the Latin
America JVs and the Spain Joint Venture. PanAmSat, Televisa and S Company have
entered into the DTH Option Purchase Agreement whereby after the Share
Repurchase PanAmSat will sell the DTH Options to either Televisa, S Company
and/or their designees for a purchase price of $225 million. The closing of
the DTH Sale will occur substantially concurrently with receipt by S Company
of the consideration to be paid by New PanAmSat in connection with the Univisa
Contribution. PanAmSat has received the written opinion of Salomon Brothers,
PanAmSat's financial advisor, to the effect that as of September 19, 1996 and
based upon and subject to the qualifications described therein, the
consideration to be received by PanAmSat for the sale of the DTH Options
represents fair value to PanAmSat for the DTH Options from a financial point
of view. See "THE DTH SALE."
 
  On September 20, 1996, PanAmSat agreed to provide Televisa Spain transponder
capacity on five Ku-band transponders on PAS-3, at least three of which will
be used to deliver television services to Spain, which may include DTH
services. The transponder service fees reflect market rates.

<PAGE>
 
  As of March 31, 1995, PanAmSat entered into a contract with HAC for the
construction and delivery of PAS-5. The HAC PAS-5 Contract calls for the
delivery of PAS-5 in the spring of 1997. Payments representing approximately
80% of the total cost of the satellite will be made during the period of the
satellite's construction and upon completion of the satellite's in-orbit
testing, with the remainder of such costs to be paid in the form of incentive
payments made over the 15-year period following launch, based upon the
satellite's orbital performance. PanAmSat has the option of prepaying the
incentive obligations at any time, which incentive obligations are subject to
reduction or refund if the satellite fails to meet specific technical
operating standards. The HAC PAS-5 Contract provides for a limited pre-launch
warranty by HAC which requires HAC to correct or replace any non-conforming
goods with conforming goods, if such correction or replacement can be
reasonably accomplished as determined by HAC. There are limited liquidated
damages of up to $1.0 million payable by HAC in the event of a late delivery
which is the fault of HAC. If the delivery is delayed due to the fault of
PanAmSat, PanAmSat will be obligated to pay to HAC its reasonable costs
incurred as a result of the delay plus a 15% profit component.
 
  As of March 31, 1995, PanAmSat entered into a binding letter agreement with
HAC, acting through Hughes Space and Communications Company ("HSCC") for HSCC,
through its affiliate, HCSS, to provide TT&C services for PAS-5 that are
equivalent to the TT&C services that are provided to PanAmSat by HCSS. Radio
frequency (RF) links for the PAS-5 TT&C service and, at HSCC's request, for
PAS-3, are to be provided by PanAmSat. The price for the PAS-5 TT&C services
is less than the price charged by HCSS for TT&C services for either PAS-2 or
PAS-3. The letter agreement calls for other terms and conditions to be
consistent with terms and conditions under which TT&C services for PAS-2 and
PAS-3 are provided, subject to certain specified exceptions as to which terms
are more favorable to PanAmSat. Although the PAS-5 TT&C agreement contemplated
the completion of a full-scale agreement by December 1, 1995, that has not yet
occurred. While PanAmSat believes that such agreement will be reached, if it
is not, the letter agreement allows the details of the contract to be
determined by binding arbitration, if necessary.
 
  The law firm of Ivey, Barnum & O'Mara, of which James W. Cuminale, Senior
Vice President and General Counsel of PanAmSat, was a partner, provided
certain legal services to PanAmSat and received nominal fees from PanAmSat
during the fiscal year ended December 31, 1995.
 
  The communications engineering consulting firm of Rubin, Bednarek &
Associates, of which Robert A. Bednarek, Senior Vice President, Engineering
and Operations, of PanAmSat, was a principal during 1995, provides engineering
and technical services to PanAmSat and received fees from PanAmSat of
approximately $1.4 million for the fiscal year ended December 31, 1995. Mr.
Bednarek terminated his association with Rubin, Bednarek & Associates as of
December 31, 1995.
 
  After the Closing Date, Patrick J. Costello, the current Chief Financial
Officer of PanAmSat, will no longer be an officer of PanAmSat or New PanAmSat.
However, Mr. Costello will provide consulting services to New PanAmSat for a
transitional period following the Closing for a fee equal to a pro rata share
of his current salary. In addition, Mr. Costello also has been appointed by
the Class A Holders to serve as a Director of New PanAmSat. See "MANAGEMENT OF
NEW PANAMSAT--Board of Directors." Mr. Costello, who will no longer serve as
Chief Financial Officer of PanAmSat after the Closing Date, will be entitled
to receive a severance payment of $975,000 as a result of the Reorganization.
See "THE REORGANIZATION--Interests of Certain Persons in the Reorganization."
 
  Between 1992 and March 2, 1995, PanAmSat operated as the Partnership and
prior to 1992 as a sole proprietorship and through other forms of
organization. On March 2, 1995, pursuant to an amended Exchange and
Subscription Agreement and Plan of Reorganization, PanAmSat, the Partnership
and its partners consummated the Conversion. In March 1995, in connection with
the Conversion, the Partnership granted to Lourdes Saralegui, Executive Vice
President of PanAmSat, a 43% limited partnership interest in the Partnership
and Ms. Saralegui became a limited partner of the Partnership. Concurrently
with such transaction, the Anselmo Group contributed to the Partnership a
limited partnership interest in the Partnership in like amount. Any income tax
deduction in an amount which does not exceed $50 million in value which is
available to the Partnership as a result of such transaction has been
specially allocated to the Anselmo Group.
 
  PanAmSat believes that each of the transactions described above was on terms
at least as favorable to PanAmSat as could be expected by third parties.
 
 
                                      201

  As part of the Conversion, in connection with the merger of a company
controlled by the late Rene Anselmo into PanAmSat, Mr. Anselmo and Frederick
A. Landman jointly and severally indemnified PanAmSat against undisclosed
liabilities of that company. In addition, in connection with the Conversion,
PanAmSat assumed the phantom stock plans of that company. In connection with
the termination of such plans by PanAmSat, Patrick J. Costello, Chief
Financial Officer of PanAmSat, and Robert A. Bednarek, Senior Vice President,
Engineering and Operations of PanAmSat, received cash payments aggregating
approximately $964,000 during fiscal 1995.
 
  Prior to the Conversion, the Partnership made quarterly distributions to its
limited partners to pay income taxes for each year that the Partnership had
taxable income. Such distributions were calculated using the highest effective
combined U.S. federal, state, local and foreign tax rate that was imposed on
any partner who was a U.S. person with respect to such partner's allocable
share of taxable income of the Partnership for such taxable year. The
Partnership Agreement provided that the tax distribution for each taxable year
was to be reasonably estimated by the Managing Committee of the Partnership.
If the required tax distribution for a taxable year was greater or less than
the aggregate of the estimated amounts so distributed by the Partnership, the
Partnership was obligated to distribute the excess to the partners, or the
partners were obligated to contribute the deficiency to the Partnership, in
proportion to their percentage interests. There were no such tax distributions
for the year ended December 31, 1996.
 
HUGHES PARTIES
 
  Galaxy has been operated since its inception as a separate business unit of
HCI, but has been party to many ongoing arrangements and relationships with
other companies affiliated with HCI and HE. These inter-company arrangements
have included HE's provision of payroll, research, insurance (including
medical, dental and vision insurance for Galaxy employees), other employee
benefits, retirement and incentive plans, professional development, medical
services, long-term disability and general administrative services. Galaxy
also has received certain support services from HE's finance, human resources,
administration, communications, legal, marketing, technology and research
departments. All of such services have been provided to Galaxy by HE on a cost
basis. Galaxy also has provided miscellaneous support services to DTVI,
formerly a business unit of HCI and incorporated as a separate subsidiary in
January 1996, which services have included administrative, legal, human
resources and finance services. Galaxy does not anticipate that it will
provide such services to DTVI after the Closing Date. Galaxy has contracted
with HSC for the construction of each of Galaxy's existing in-orbit satellites
and Galaxy's satellites currently under development. From January 1, 1994 to
December 31, 1996, Galaxy paid to HSC approximately $333 million in the
aggregate in connection with the procurement of long lead items and/or
construction of Galaxy I-R, Galaxy III-R, Galaxy VIII-i, Galaxy IX, Galaxy X,
Galaxy XI, Galaxy XIII and Galaxy XIV, and, from January 1, 1997 going
forward, Galaxy has paid and expects to pay to HSC approximately $450 million
pursuant to existing satellite contracts and new agreements for the
construction of Galaxy XI, Galaxy XII, Galaxy XIII and Galaxy XIV which Galaxy
intends to enter into prior to the Closing Date. Affiliates of HE also have
been responsible for arranging for the launch of all of Galaxy's existing in-
orbit satellites. Galaxy currently is a party to various other agreements with
affiliates of HE with respect to, among other things, (i) the provision of
rights to three satellite launch opportunities previously acquired by an
affiliate of HE and involving aggregate consideration of approximately $220
million, (ii) the provision of TT&C services for satellites owned by HE
affiliates DIRECTV and American Mobile Satellite Corporation in exchange for
aggregate consideration of approximately $6.4 million per year, (iii) the
lease of transponder capacity to an affiliate of DTVI and Hughes Network
Systems for aggregate consideration of approximately $82.4 million per year,
(iv) the leaseback of Galaxy III-R pursuant to which Galaxy is obligated to
make lease payments of approximately $39.2 million per year for the term of
the lease or until Galaxy exercises its Early Buy Out Option with respect to
such satellite, and (v) the lease by Galaxy of its corporate headquarters and
network operations facility in Long Beach, California for approximately $.7
million per year. Prior to the Closing Date, Galaxy also intends to enter into
a new operating lease agreement with an affiliate of DTVI with respect to the
lease of transponder capacity on Galaxy VIII-i for approximately $60 million
per year (which transponder capacity will replace some of the transponder
capacity utilized by such affiliate pursuant to clause (iii) in the preceding
sentence).

  For a one-year transition period after the Effective Time, Kenneth N.
Heintz, who will be Executive Vice President and Chief Financial Officer of
New PanAmSat, will continue to be a vice president of and employed by HE. It
is expected that during such transition period New PanAmSat will pay HE for
the services provided by Mr. Heintz to New PanAmSat. See "MANAGEMENT OF NEW
PANAMSAT--Employment Agreements."
 
  Both Mr. Heintz and Mr. Brown will be reimbursed for all of their expenses
incurred in connection with their relocation to Greenwich, Connecticut. New
PanAmSat will reimburse Mr. Heintz for his expenses up to $100,000; any
additional costs will be paid for by HE. Mr. Brown will be fully reimbursed by
New PanAmSat. Among the expenses that will be covered are home marketing
assistance, home purchase assistance, house closing costs, interim living
expenses and actual moving costs. In addition, New PanAmSat and HE will
provide for spouse career assistance, tax assistance and a relocation
allowance. PanAmSat has loaned to Mr. Brown $92,250 at an interest rate of 5
7/10% to facilitate Mr. Brown's purchase of a home in Connecticut. It is
anticipated that he will repay this loan by the end of May 1997.

              PROPOSAL TO APPROVE AND ADOPT THE CHARTER AMENDMENT
 
  One of the purposes of the Special Meeting is to obtain the approval and
adoption of the Charter Amendment by PanAmSat's stockholders. The PanAmSat
Certificate of Incorporation currently sets forth the name of PanAmSat as
"PanAmSat Corporation." The Reorganization Agreement requires that PanAmSat
change its name so that New PanAmSat may be named "PanAmSat Corporation." One
of the purposes of the Charter Amendment is to change the name of PanAmSat to
"PanAmSat International Systems, Inc." immediately prior to the Merger.
Accordingly, the PanAmSat Board deemed advisable and approved an amendment to
Article One of the PanAmSat Certificate of Incorporation by unanimous written
consent dated April 15, 1997 and found such amendment to be in the best
interests of PanAmSat and its stockholders.
 
 
  The PanAmSat Certificate of Incorporation currently requires or may be
deemed to require that any share of PAS Class A Common Stock or PAS Class B
Common Stock that is transferred to any entity other than a "Permitted
Transferee" under the PanAmSat Certificate of Incorporation will lose its
status as such and be converted into a share of PAS Ordinary Common Stock. See
"COMPARISON OF STOCKHOLDERS' RIGHTS." Another purpose of the Charter Amendment
is to clarify that the direct holder of the PAS Class B Common Stock would not
participate in the Merger by reason of such conversion or deemed conversion of
the shares of PAS Class B Common Stock upon the consummation of the Univisa
Contribution immediately prior to the Merger. It is accordingly a condition to
the consummation of the Reorganization that an amendment to the PanAmSat
Certificate of Incorporation to clarify that the shares of PAS Class A Common
Stock and PAS Class B Common Stock will not be converted into shares of PAS
Ordinary Common Stock in connection with the Reorganization Agreement, the
Univisa Contribution Agreement and the transactions contemplated thereby, be
approved by the requisite holders of PAS Common Stock and be effective prior
to the consummation of the Univisa Contribution. Accordingly, the PanAmSat
Board deemed advisable and approved an amendment to Article Five, paragraph
5.8(a) of the PanAmSat Certificate of Incorporation by unanimous written
consent dated January 21, 1997 and found such amendment to be in the best
interests of PanAmSat and its stockholders. The number of shares of PAS Class
A Common Stock and PAS Class B Common Stock that would be affected by this
amendment would be 21,231,415 and 40,459,431, respectively. See "THE SPECIAL
MEETING--Record Date; Shares Entitled to Vote; Vote Required," and "THE
REORGANIZATION AGREEMENT--Terms of the Reorganization."
 
  The PanAmSat Certificate of Incorporation currently requires that in any
merger, consolidation or business combination, the consideration to be
received per share by the holders of PAS Class A Common Stock, PAS Class B
Common Stock and PAS Ordinary Common Stock must be identical for each class of
stock. In the Merger, the direct holder of the PAS Class B Common Stock will
not receive the Merger Consideration; instead, the indirect parent of such
holder, S Company, will receive consideration pursuant to the Univisa
Contribution Agreement equal in amount and form (subject to proration, as
applicable) to the Merger Consideration payable on account of each share of
PAS Class A Common Stock and PAS Ordinary Common Stock. Furthermore, S Company
may be deemed to receive certain additional benefits from the Share Repurchase
and the DTH Sale. A further purpose of the Charter Amendment is to clarify
that receipt of consideration equal to the Merger Consideration and any
additional benefits arising from the Reorganization by the indirect holder of
the PAS Class B Common Stock, instead of by the direct holder thereof, would
not violate the PanAmSat Certificate of Incorporation. Accordingly, the
PanAmSat Board deemed advisable and approved an amendment to Article Five,
paragraph 5.10 of the PanAmSat Certificate of Incorporation by action at its
meeting on January 27, 1997 and found such amendment to be in the best
interests of PanAmSat and its stockholders.
 
  Pursuant to the Principal Stockholders Agreement, the beneficial owners of
all of the issued and outstanding shares of PAS Class A Common Stock and PAS
Class B Common Stock have agreed to vote all of their shares of PAS Common
Stock in favor of the Charter Amendment. Immediately before the Record Date,
the holders of PAS Class A Common Stock voluntarily converted the number of
shares of PAS Class A Common Stock necessary to constitute a majority of the
outstanding shares of PAS Ordinary Common Stock from PAS Class A Common Stock
into PAS Ordinary Common Stock. On the Record Date, the beneficial owners of
all of the
 
                                      204
<PAGE>
 
issued and outstanding shares of PAS Class A Common Stock and PAS Class B
Common Stock held 100% of the voting power of their respective classes of
stock and the holders of Converted Shares held approximately 50.1% of the
voting power of the PAS Ordinary Common Stock. Accordingly, approval of the
Charter Amendment by each class of PanAmSat's stockholders is assured.
 
                                 LEGAL MATTERS
 
  The legality of the shares of New PAS Common Stock to be issued in
connection with the Merger is being passed upon for New PanAmSat by Chadbourne
& Parke LLP. Certain tax consequences of the Merger also will be passed upon
by Chadbourne & Parke LLP.
 
                                    EXPERTS

                         FUTURE STOCKHOLDER PROPOSALS
 
  If the Reorganization is consummated prior to May 20, 1997, the first annual
meeting of the stockholders of New PanAmSat is expected to be held in 1997 and
PanAmSat will not hold its 1997 Annual Meeting of Stockholders. If the
Reorganization is not consummated by May 20, 1997, the 1997 Annual Meeting of
Stockholders of PanAmSat is expected to be held on or about May 30, 1997. Any
proposal to be included in the Proxy Statement for PanAmSat's 1997 Annual
Meeting of Stockholders must have been received by PanAmSat no later than
December 15, 1996 in a form that complies with applicable regulations.
 
  Subject to the foregoing, if any New PanAmSat stockholder intends to submit
a proposal at the New PanAmSat 1997 Annual Meeting of Stockholders and wishes
such proposal to be considered for inclusion in the proxy materials for such
meeting, such holder must submit the proposal to the Secretary of New PanAmSat
in writing so as to be received at the offices of New PanAmSat by December 15,
1997. The New PanAmSat Bylaws require that for nominations or other business
to be properly brought before an annual meeting by a stockholder, the
stockholder must have given timely notice thereof in writing to the Secretary
of New PanAmSat and such other business must otherwise be a proper matter for
stockholder action. In general, to be timely, a stockholder's notice shall be
delivered to the Secretary at the principal executive offices of New PanAmSat
not later than the close of business on the 60th day nor earlier than the
close of business on the 90th day prior to the annual meeting. Notices must be
sent to the Corporate Secretary, New PanAmSat, One Pickwick Plaza, Greenwich,
Connecticut 06830. Such proposals must also meet the other requirements of the
rules of the Commission relating to stockholder proposals.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
PanAmSat Corporation:
 
  We have audited the accompanying consolidated balance sheets of PanAmSat
Corporation (a Delaware Corporation) and subsidiaries and predecessor entity
as of December 31, 1996 and 1995, and the related consolidated statements of
operations, stockholders' equity and partners' equity, and cash flows for each
of the three years in the period ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of PanAmSat
Corporation and subsidiaries and predecessor entity as of December 31, 1996
and 1995 and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1996 in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

(1) PRINCIPLES OF PRESENTATION:
 
  On March 2, 1995, pursuant to the amended Exchange and Subscription
Agreement and Plan of Reorganization, PanAmSat Corporation (the "Company"),
PanAmSat, L.P. (the "Partnership") and its partners consummated various
transactions whereby the Company acquired the Partnership and converted it to
corporate form. In connection therewith, (i) Rene Anselmo and affiliated
persons and entities (the "Anselmo Group") exchanged their interests in the
Partnership for shares of Class A Common Stock representing approximately
49.66% of the outstanding common stock of the Company, (ii) Univisa Satellite
Holdings, Inc. ("Univisa") exchanged its interest in the Partnership for
shares of Class B Common Stock representing approximately 50.15% of the
outstanding common stock of the Company and (iii) a partner of the Partnership
exchanged his interest in the Partnership for shares of Common Stock
representing approximately 0.19% of the outstanding common stock of the
Company. The Amended and Restated Certificate of Incorporation of the Company
provides, among other things, the holders of the Class A Common Stock with the
ability to elect a majority of the Company's board of directors and the
Anselmo Group and Univisa with a veto over certain significant corporate
transactions of the Company. On September 27, 1995, the Company completed an
initial public offering of 18,920,000 shares of common stock, including
4,595,676 shares held by certain selling stockholders, and received net
proceeds of approximately $229 million.
 
  Prior to the conversion, the Partnership operated under terms of the Amended
and Restated Agreement of Limited Partnership (the "Partnership Agreement")
dated December 31, 1992. Univisa, a wholly owned subsidiary of Grupo Televisa,
S.A. ("Televisa") and a general partner in the Partnership, made cash
investments in partnership units of $200 million.
 
  All assets and liabilities transferred were reflected at historical cost by
the Company and the Partnership. Accordingly, the accompanying financial
statements reflect the combined assets, liabilities, equity and operations of
the Company and the Partnership as if they had operated as a single entity
since their respective dates of organization. The accompanying financial
statements include the accounts of the Company and its wholly-owned
subsidiaries. All significant intercompany transactions and balances have been
eliminated.
 
(2) BUSINESS DESCRIPTION:
 
  The business of the Company is to operate an international
telecommunications satellite system. The Company currently provides video,
data and voice telecommunications services in North America, South America,
Europe and Africa via its PAS-1 satellite ("PAS-1") and PAS-3 satellite ("PAS-
3"), in the Asia-Pacific region via its PAS-2 satellite ("PAS-2") and in
Europe, Africa and Asia via its PAS-4 satellite ("PAS-4"). PAS-1 was launched
in June 1988, PAS-2 in July 1994, PAS-4 in August 1995 and PAS-3 in January
1996. The Company currently intends to construct and deploy four additional
satellites over the Atlantic, Atlantic, Indian, and Pacific ocean regions,
respectively (see Note 6). In addition, the Company intends to pursue
providing satellite capacity to customers offering direct-to-home ("DTH")
services internationally and has entered into various agreements relating to
the provision of satellite capacity for DTH services in Latin America and
Spain (see Note 4). The development, launch and operation of
telecommunications satellites involve significant risks of construction
delays, launch delays, launch failure or damage to a satellite following its
launch which may reduce its performance or result in its destruction. Such
delays, launch failures or damage would adversely affect operating results.
 
  The Company holds a license from the Federal Communications Commission
("FCC") to operate PAS-1 in geostationary orbit at 45 degrees West Longitude,
PAS-2 at 191 degrees West Longitude, PAS-3 at 43 degrees West Longitude and
PAS-4 at 68.5 degrees East Longitude. The Company has obtained or applied for
authorizations from the FCC for an all Ku-band satellite, additional C/Ku-band
hybrid satellites and for new Ka-band satellites. Conditional authority has
been received for additional satellites at 72 degrees East Longitude and 43
degrees West Longitude (to be co-located with PAS-3). The Company has also
filed applications with the

FCC for additional C/Ku-band hybrid satellites at 194 degrees West Longitude,
58 degrees West Longitude (the Company has informally requested the FCC
associate this application with the 81 degree West Longitude orbital
location), 68.5 degrees East Longitude (to be co-located with PAS-4), 79
degrees West Longitude (the Company has informally requested the FCC to
associate this application with the 81 degree West Longitude orbital
location), and 93 degrees West Longitude. The Company has filed applications
with the FCC for Ka-band satellites at 58 degrees, 79 degrees, 43 degrees, 45
degrees, and 103 degrees West Longitude, and at 169 degrees, 166 degrees, 68.5
degrees, and 72 degrees East Longitude. The Company's wholly-owned subsidiary,
PanAmSat Carrier Services, Inc., has an FCC authorization to provide common
carrier service via PAS-1. The Company also holds licenses to provide domestic
and international satellite communications services in France, Germany, the
United Kingdom, Ecuador, Argentina, Pakistan and Japan.
 
  The Company provides telecommunications services under long-term and
occasional (spot) booking arrangements, a majority of which are with foreign
entities, including Univisa affiliates.
 
  The following summarizes the Company's foreign and domestic sales:

  Future cash payments expected from customers under all long-term
arrangements for satellites in service (see Note 5) aggregate approximately
$2.4 billion as of December 31, 1996, excluding any DTH service agreements
described in Note 4. Such cash payments may be reduced for outage or
transponder failure and may be further reduced for "lowest price" provisions
for like transponder capacity given to similarly situated customers.
Approximately $229.8 million of such arrangements at December 31, 1996 are
terminable at the customer's option after a minimum service period.
 
(3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
USE OF ESTIMATES--
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of certain estimates by
management in determining the reported amount of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ materially
from those estimates.
 
REVENUE RECOGNITION--
 
  The Company enters into contracts to provide satellite capacity and related
services. These contracts generally provide for the use of satellite and, in
certain cases, earth station and teleport facilities for periods ranging from
one year to the life of the satellite. Virtually all contracts stipulate
payment terms in U.S. dollars.
 
  Service agreements and occasional (spot) services. Revenues under service
agreements and occasional (spot) services are recognized as services are
performed and billed. The Company has certain obligations, including providing
spare or substitute capacity if available, in the event of satellite service
failure under certain long-term agreements. If no spare or substitute capacity
is available, the agreements may be terminated. Except for certain deposits,
the Company is not obligated to refund payments previously made.

                             PANAMSAT CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
  Transponder contracts. Long-term transponder contracts provide for use of a
transponder for the life of the transponder. Payments for the transponder are
made over a shorter period, usually seven years. Uncured transponder failures
during the payment period result in cessation of customer payments. The
Company is not required to refund any portion of customer payments if a
transponder fails. The economic risk of loss passes to the customer upon
receipt of final payment by the Company.
 
  Revenue under transponder contracts is recognized ratably over the payment
period, and a pro rata share of the cost of the satellite system and a pro
rata share of future telemetry, tracking and control ("TT&C") costs for the
life of the satellite are expensed over the same period. Accordingly, no
revenue will be recognized beyond the payment period, usually seven years, and
all estimated costs related to these transponders will have been recognized as
of the final payment date. Revenues of approximately $3.2 million, $3.6
million, and $4.5 million for the years ended December 31, 1996, 1995 and
1994, respectively, are included in the accompanying statements of operations
relating to such contracts.
 
CASH AND CASH EQUIVALENTS--
 
  Cash and cash equivalents consists of cash on hand and highly liquid
investments with maturities at date of acquisition of three months or less.
 
ACCOUNTS RECEIVABLE--
 
  Accounts receivable include amounts earned under service agreements and
occasional (spot) services which are billable as performed.
 
MARKETABLE SECURITIES--
 
  Marketable securities consist of debt securities issued by the United States
Treasury and other U.S. government corporations and agencies, corporate debt
securities and other securities (primarily investments in money market funds
consisting of the aforementioned securities) and have maturity dates within
one year. The carrying amounts of these securities are approximately $130.8
million, $103.7 million and $144.7 million, respectively at December 31, 1996.
The Company has classified the debt securities as held-to-maturity and,
accordingly, are recorded at amortized cost, which approximates fair value.
The money market funds are recorded at cost plus accrued income, which
approximates fair value. Proceeds of these securities are intended to be used
for the satellite systems under development and, accordingly, are classified
as long-term.
 
SATELLITES AND OTHER PROPERTY AND EQUIPMENT--
 
  Satellites and other property and equipment are stated at historical cost.
The cost of the PAS-1, PAS-2, PAS-3 and PAS-4 satellite system includes all
construction costs, incentive obligations, launch costs, launch insurance,
direct development costs, and capitalized interest. Substantially all other
property and equipment consists of the Company's teleport facilities.
 
  Depreciation and amortization are provided using the straight-line method
over the estimated useful lives of the respective assets as follows:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

  The estimated useful lives of the satellites were determined by an
engineering analysis performed at the in-service dates. The original estimated
useful lives are periodically reviewed using current TT&C data provided by
various service providers. To date, no significant change in the original
estimated useful lives has resulted. The telecommunications industry is
subject to rapid technological change which may require the Company to revise
the estimated useful lives of its satellites and communications equipment or
to adjust their carrying amounts.
 
  Research and development costs and maintenance and repairs are charged to
operations as incurred.
 
SATELLITE SYSTEMS UNDER DEVELOPMENT--
 
  Expenditures for satellite systems under development include construction,
launch and launch insurance progress payments, certain direct development
costs, capitalized interest, and components for a spare satellite (see Note
6).
 
  Cost of satellites which are lost at launch are carried, net of any
insurance proceeds, in satellite systems under development. The remaining net
amounts are depreciated proportionately over the estimated useful lives of
related satellites placed in service.
 
DEBT ISSUANCE COSTS--
 
  Debt issuance costs relate to the issuance of the Company's 9 3/4% Senior
Secured Notes ("Senior Secured Notes") and the Company's 11 3/8% Senior
Subordinated Discount Notes ("Discount Notes") in August 1993. These costs
totaled approximately $16.2 million at December 31, 1996, and are being
amortized over the life of the Notes using the interest method. The
accumulated amortization at December 31, 1996 is approximately $6.7 million.
 
INCOME TAXES--
 
  As a result of the conversion of the Partnership to a corporation on March
2, 1995, the Company files corporate federal and state income tax returns.
This change in tax status was recognized by establishing deferred tax assets
and liabilities for temporary differences between the tax basis of assets and
liabilities and amounts reported in the balance sheet at the date of
conversion (see Note 9).
 
  The current provision for income taxes represents actual or estimated
amounts payable or refundable on tax returns filed or to be filed for each
year. Deferred tax assets and liabilities are recorded for the estimated
future tax effects of temporary differences between the tax basis of assets
and liabilities and amounts reported in the balance sheets. The overall change
in deferred tax assets and liabilities for the period measures the deferred
tax expense for the period. Effects of changes in enacted tax laws on deferred
tax assets and liabilities are reflected as adjustments to tax expense in the
period of enactment.
 
EARNINGS PER SHARE--
 
  The unaudited pro forma earnings per share have been calculated and
presented on a pro forma basis (i) to reflect the pro forma adjustments to the
income tax provision as if the Company had been incorporated and (ii) as if
the shares issued to effect the conversion of the Partnership to corporate
form and to effect a .859399 for 1 reverse split of the Company's common stock
on September 15, 1995 were outstanding for all periods presented and (iii) to
reflect the weighted average number of common shares issued in the Company's
initial public offering. When dilutive, stock options are included in the
weighted average number of shares outstanding using the treasury stock method.

NET INCOME (LOSS) ALLOCATION--
 
  The Partnership Agreement had provided that profits and losses of the
Partnership be allocated among the partners' percentage interests.
 
(4) SATELLITE CAPACITY FOR DTH SERVICES:
 
  In November 1995, the Company announced that it would serve as a satellite
service provider for a Latin America DTH service ("Latin America DTH") to be
offered by the Globo Organization ("Globo"), Televisa, The News Corporation
Limited ("News Corp.") and Tele-Communications International, Inc. ("TCI"). On
February 29, 1996, the Company signed a binding letter agreement with Globo,
Televisa, and News Corp. (the "1996 Letter Agreement") to provide service to a
series of joint ventures (the "Latin America JVs") to be formed by them and
TCI on 48 transponders ultimately on PAS-5 and PAS-6 with temporary service on
PAS-3 pending the commencement of service on PAS-6. Also under the 1996 Letter
Agreement, Globo, Televisa, and News Corp. have agreed to proportionally
guarantee 100 percent of the fees for transponder services to the Latin
America JVs. These guarantee obligations may be assigned to TCI and, with the
Company's prior written consent, to new equity participants in the Latin
America JVs. The Company will receive minimum service fees equivalent to the
Company's best estimate of the cost per transponder to the Company of
designing, launching, operating and insuring each satellite for the
transponders used by the Latin America JVs. The Company also will receive
additional revenue based on subscriber revenues of the Latin America JVs above
a certain threshold, except that the transponders on PAS-3 and PAS-6 that will
be used by the Latin America JV operating in Brazil will be charged on a fixed
fee basis. On June 26, 1996, a full-scale agreement was executed for service
in Brazil on twelve transponders (the "Brazil Agreement"). The 1996 Letter
Agreement remains in force for the remaining 36 transponders. Globo and News
Corp. have proportionately guaranteed the obligations under the Brazil
Agreement.
 
  On September 20, 1996, the Company entered into an agreement with Televisa
S.A. de C.V., an affiliate of Televisa, to provide transponder service on up
to five PAS-3 Ku-band transponders, at least three of which will be used for
distribution of television services in Spain, which may include DTH services.
The service fees reflect market rates. This agreement superseded a verbal
agreement in principle with Televisa whereby PanAmSat and Televisa had
intended to form a joint venture to offer DTH services in the Iberian
Peninsula.
 
  Concurrently with the Combination (see Note 13) and immediately following
the Univisa Contribution, 7.5 million shares of New PanAmSat common stock
received by Satellite Company, L.L.C., a Nevada limited liability company ("S
Company") and a subsidiary of Televisa, in connection with the Univisa
Contribution will be repurchased by New PanAmSat for $225 million. Following
such repurchase, either Televisa, S Company and/or their designees will
purchase for $225 million all of PanAmSat's rights to purchase from Televisa
equity interests in certain joint ventures to be formed to offer DTH services
in Latin America and the Iberian Peninsula.
 
  The Company also has significant investments in and commitments for PAS-5
and PAS-6 (see Note 6) which it had intended to use in the proposed DTH
business. Pursuant to the Reorganization Agreement, it is anticipated that the
Company's rights to acquire equity interests in the Latin American JVs will be
sold at the closing of the Reorganization.
 
(5) SATELLITES AND OTHER PROPERTY AND EQUIPMENT:
 
  The Company's principal operating assets consist of PAS-1, PAS-2, PAS-3 and
PAS-4. The Company has in-orbit insurance coverage of $60 million for PAS-1
through August 26, 1997. In-orbit insurance coverage for PAS-2, PAS-3 and PAS-
4 of $188 million, $215 million and $212 million, respectively, expires on May
21, 1997. The Company intends to obtain new in-orbit insurance coverage to
become effective upon these expiration dates. The Company operates terrestrial
sites and network control centers in Homestead, Florida, Ellenwood, Georgia
and Napa, California.

(6) SATELLITE SYSTEMS UNDER DEVELOPMENT:
 
  The Company has contracted with Hughes Aircraft Company ("Hughes") to
construct a satellite, PAS-5, to be deployed over the Atlantic Ocean region.
The Company has also contracted with Space Systems/Loral ("Loral") for the
construction and delivery of PAS-6, PAS-7 and PAS-8, and for the option to
purchase up to two additional satellites and up to four spare satellites
pursuant to the Loral Satellite Contract. PAS-6, PAS-7 and PAS-8 are to be
deployed over the Atlantic, Indian and Pacific ocean regions, respectively.
PAS-5 and PAS-6 will be suitable for DTH broadcast purposes and are scheduled
to be delivered in 1997. PAS-7 and PAS-8 are scheduled to be delivered in 1997
and 1998, respectively.
 
  The Hughes and Loral contract terms include progress payments payable
monthly during the period of the satellites' construction and incentive
obligations payable monthly with interest ranging from 9.5% to 10% per annum
over a period of 10-15 years, scheduled to commence after the delivery and
launch of the satellites. The incentive obligations are subject to reduction
or refund (as applicable) if the satellites fail fully to meet specific
technical operating standards. The contracts contain rights to cancellation,
which would result in the forfeiture of all progress payments with escalating
termination payments.
 
  The Company has entered into launch contracts with International Launch
Services ("ILS") for the launch of three satellites and Arianespace S.A.
("Arianespace") for the launch of one satellite. The Company expects to launch
PAS-5 and PAS-8 under the ILS contract from Khazakhstan using Proton rockets
and PAS-6 using an Ariane IV launcher. The Company has also entered into a
multi-launch agreement ("Multi-Launch Agreement") with Arianespace which
provides for one firm launch, which the Company plans to use for PAS-7, and
rights for additional launches. The Company has exercised its rights for an
additional launch in late 1999 or early 2000 for an unspecified satellite. The
launch contracts provide that the Company may terminate such contracts at its
option, and the contracts include termination liability schedules that
increase in magnitude as the timing of any such termination approaches the
date of launch. The maximum termination liability, calculated in accordance
with such schedules, for launch services that have been ordered in connection
with any individual launch (including postponement fees) is approximately
$45.0 million. Payments made by the Company prior to the Company's election to
terminate any such launch contract are offset against any such liability owed.
 
  The Company has obtained policies for up to an aggregate of $1.2 billion of
launch insurance for PAS-5, PAS-6, PAS-7, PAS-8 and a replacement satellite,
or if no replacement is required, a satellite to be designated as PAS-9. The
Company expects the total cost (including costs for engineering, construction,
launch, launch insurance, direct development costs and certain components for
a spare satellite) of PAS-5, PAS-6, PAS-7, and PAS-8 to be approximately $846
million, of which the Company has paid $429 million at December 31, 1996. The
Company has contracted commitments for approximately $417 million at December
31, 1996 related to its satellite systems under development.

(a) Interest on the Senior Secured Notes is payable semi-annually on February
    1 and August 1 of each year, commencing February 1, 1994. Interest
    incurred for the years ended December 31, 1996 and 1995 totaled
    approximately $17 million per year. The Senior Secured Notes are
    redeemable after August 1, 1998, in whole or in part, at the option of the
    Company, at a price of 101.625% declining to 100% of principal plus
    accrued and unpaid interest, if any, to the date of redemption. The Senior
    Secured Notes rank senior in right of payment to all subordinated
    indebtedness of the Company and pari passu in right of payment with all
    Senior Debt (as defined in the indenture for the Senior Secured Notes).
    The Senior Secured Notes are secured by liens on certain assets of the
    Company, including PAS-1, PAS-2, PAS-3 and PAS-4.
(b) Interest on the Discount Notes accretes prior to August 1, 1998 at which
    time the principal outstanding will be approximately $460.2 million.
    Interest accreted for the years ended December 31, 1996 and 1995 totaled
    approximately $40.3 million and $36.1 million, respectively. After August
    1, 1998, interest on the Discount Notes will be payable semi-annually on
    February 1 and August 1 of each year, commencing on February 1, 1999. The
    Discount Notes are not redeemable prior to August 1, 1998. Thereafter, the
    Discount Notes are redeemable, in whole or in part, at the option of the
    Company, at a price of 104.266% declining to 100% of principal plus
    accrued and unpaid interest, if any, to the date of redemption. The
    Company will be required to redeem 25% of the original aggregate principal
    amount of the Discount Notes at a redemption price equal to 100% of the
    principal amount thereof together with accrued and unpaid interest on each
    of August 1, 2001 and August 1, 2002. The Discount Notes are unsecured and
    are subordinated in right of payment to all present and future Senior Debt
    of the Company, including the Senior Secured Notes.
 
  The indentures relating to the Senior Secured Notes and Discount Notes
contain restrictive covenants that, among other things, impose limitations on
the Company and its subsidiaries with respect to their ability to (i) incur
additional indebtedness; (ii) make certain investments; (iii) sell assets or
apply the proceeds therefrom; (iv) enter into transactions with affiliates and
(v) pay dividends. Under the financial covenants included in these
restrictions the Company is not currently permitted to incur additional
indebtedness, except as described below, or to make certain investments or pay
dividends.

  The fair value of the Company's debt exceeded the carrying value by
approximately $46.5 million at December 31, 1996. Capitalized interest totaled
approximately $39.5 million, $37.8 million and $41.0 million in 1996, 1995 and
1994, respectively, and is included in satellite systems under development.
 
(8) PREFERRED STOCK
 
  On April 21, 1995, the Company consummated the sale of 275,000 shares of
Preferred Stock and received proceeds of approximately $261.5 million, net of
underwriting discounts and commissions of approximately $10.7 million and
offering expenses of approximately $2.5 million. The Company anticipates that
all of such net proceeds will be applied to the development, construction and
launch of PAS-5 and PAS-6.
 
  Dividends on the Preferred Stock are payable quarterly in arrears commencing
on July 15, 1995. On or before April 15, 2000, the Company may, at its option,
pay dividends in cash or in additional fully paid and non-assessable shares of
Preferred Stock having an aggregate liquidation preference equal to the amount
of such dividends. After April 15, 2000, dividends may be paid only in cash.
As of December 31, 1996, 340,122 shares have been issued and accrued.
 
  The Preferred Stock is not redeemable prior to April 15, 2000. On or after
April 15, 2000, the Preferred Stock is redeemable at the option of the
Company, in whole or in part from time to time at a redemption price of
106.375% declining to 100% of liquidation value plus accrued and unpaid
dividends. The Preferred Stock is subject to mandatory redemption in whole on
April 15, 2005 at a price equal to the liquidation preference thereof plus
accrued and unpaid dividends. Subject to certain conditions, the Company will
be required to exchange all the outstanding shares of Preferred Stock into the
Company's 12 3/4% Senior Subordinated Notes due 2005 as soon as practicable
following the date that such exchange is permitted by the terms of the Senior
Secured Notes and the Discount Notes.
 
  The fair value of the Company's Preferred Stock exceeded the carrying value
by approximately $75.1 million at December 31, 1996.
 
(9) INCOME TAXES:
 
  Prior to the conversion, the Partnership was not subject to federal or state
income taxes. The partners were required to report their share of income or
loss in their respective income tax returns. Under the terms of the
Partnership Agreement, quarterly distributions were required for income taxes
for each year that the Partnership

                             PANAMSAT CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

had taxable income. Such distributions were calculated using the highest
effective combined U.S. federal, state, local and foreign tax rate that was
imposed on any partner which was a U.S. person with respect to such partner's
allocable share of taxable income of the Partnership for such taxable year. At
December 31, 1994, the Partnership was owed approximately $6.7 million from
its partners for quarterly tax distributions made prior to the launch of PAS-
2, which resulted in a loss for the year ended December 31, 1994. Such amounts
were repaid in 1995.
 
  Taxable income (loss) for the Company and its predecessor entities was
approximately $3.4 million and $(5.5 million) for 1995 and 1994, respectively.
Substantially all of the difference between the Company's and its
predecessors' book income and taxable income (loss) was attributable to
differences in depreciation for tax and financial reporting purposes and
customer deposits. As a result of the Partnership conversion, a net deferred
tax liability of approximately $22.9 million was recorded March 2, 1995, the
conversion date.
 
  The temporary differences that give rise to the net deferred tax liability
and their approximate tax effects as of December 31, 1996 and 1995 are as

PRO FORMA TAX EFFECTS (UNAUDITED)--
 
  The accompanying statements of operations present, on an unaudited pro forma
basis, net income for the years ended December 31, 1995 and 1994 as if the
Company had been taxed at corporate federal and state tax rates and as if the
conversion occurred on January 1, 1994. The pro forma tax effects assume the
net deferred tax liability as described above would have been provided as the
related temporary differences arose.

  Substantially all of the difference between the Company's income for
financial reporting purposes and pro forma taxable income is attributable to
the difference in depreciation and customer deposits for tax and financial
reporting purposes, and, in 1995, the permanent difference created by a $3.8
million charge related to a grant of a limited partnership interest in the
Partnership to the Executive Vice President of the Company, for which the
income tax benefit was specially allocated to the Anselmo Group.
 
(10) RELATED PARTY TRANSACTIONS:
 
  The Company has an employment agreement with Frederick A. Landman, President
and Chief Executive Officer, which terminates December 31, 1997 subject to
automatic annual renewal. Total annual base compensation is $600,000 under
this agreement.
 
  The Company has earned revenues of approximately $9.1 million, $3.9 million
and $5.0 million for 1996, 1995 and 1994, respectively, from entities
affiliated with Univisa. In addition, approximately $193.5 million of the
Company's expected future cash payments at December 31, 1996 for PAS-1 and
PAS-3 under long-term arrangements are from the same entities.
 
  The Company had a commitment to purchase certain equipment for a minimum of
$2.2 million in connection with the DTH venture described above. This
commitment has been canceled by the Company and certain costs associated with
this termination have been, and any additional costs will be, reimbursed by
Televisa under a separate indemnification agreement.
 
  Certain engineering and technical services are provided by Rubin Bednarek &
Associates, a firm in which an executive of the Company, Robert Bednarek, was
a principal until December 31, 1995. Fees paid to this firm were approximately
$1,435,000 and $1,097,000 for the years ended December 31, 1995 and 1994,
respectively.

(11) EMPLOYEE BENEFIT PLANS:
 
NON-QUALIFIED PLANS--
 
  In December 1991, a predecessor company adopted non-qualified phantom stock
plans. In connection with the conversion of the Partnership into a
corporation, the plans were assumed by the Company and the Partnership
recorded a compensation charge and a liability of approximately $2.8 million,
which was the estimated fair value of the phantom shares at that time. The
Company was obligated to adjust this liability at each balance sheet date to
the then current estimate of fair value. Accordingly, the Company recorded
additional charges of $1.7 million in 1995. The liability was paid in
connection with the Company's initial public offering.
 
  Also in connection with the conversion of the Partnership, the Executive
Vice President of the Company was granted a Partnership interest from the
Anselmo Group which was exchanged for Class A Common Stock upon the
consummation of the conversion. As a result, the Partnership recorded a non-
recurring compensation charge of approximately $3.8 million with an offsetting
increase to capital.
 
1995 STOCK PLAN--
 
  Effective March 2, 1995, the Company adopted the PanAmSat Corporation Long-
Term Stock Investment Plan (the "Stock Plan"), which provides for the granting
of non-qualified stock options, incentive stock options, alternate
appreciation rights, restricted stock, performance units and performance
shares to executive officers and other key employees of the Company, and to
other service providers, including independent contractors of the Company.
Restricted stock, performance units and performance shares may be granted in
the discretion of the Committee (as defined below) on such terms as the
Committee may decide. The maximum number of shares of common stock which may
be issued under the Stock Plan is 5,000,000, and the maximum number of shares
of common stock which may be issued to any grantee pursuant to the Stock Plan
is 2,000,000. The Stock Plan is administered by a committee of the Board of
Directors (the "Committee") consisting of at least two directors of the
Company. As of December 31, 1996, options for 1,057,345 shares of common stock
have been granted under the Stock Plan, including options for 100,000 shares
granted to non-employees. Such options are exercisable at prices ranging from
$17.00 to $28.75 per share (the stock's market price at the date of grant) and
vest ratably over five years.
 
  The Company accounts for the Stock Plan under APB Opinion No. 25. Had
compensation cost for this plan been determined consistent with SFAS No. 123,
the Company's net income (loss) and earnings (loss) per share would have been
reduced as follows:

  994,000 of the 1,057,000 options outstanding at December 31, 1996 have
exercise prices of $17 with a weighted average exercise price of $17 and a
weighted average remaining contractual life of 4 years. 199,000 of these
options are exercisable. The remaining 63,000 options have exercise prices
between $17 and $29, with a weighted average exercise price of $23 and a
weighted average remaining contractual life of 5 years. None of these options
are currently exercisable. There were no options exercisable at December 31,
1995.
 
  The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted average
assumptions used for grants in 1995 and 1996, respectively: risk-free interest
rate of 5.84 percent and 5.35 percent; expected dividend yield of 0 percent
and 0 percent; expected lives of 5.0 and 1.7 years; expected stock price
volatility of 33.2 percent and 33.2 percent.
 
COMPENSATION PLANS--
 
  On April 22, 1996, the Company adopted a General Severance Policy, an
Employee Separation Plan and an Executive Severance Pay Program, the first two
of which were amended by action of the Board of Directors on October 28, 1996.
Under the General Severance Policy, all employees would be entitled to receive
a minimum of two weeks' salary and a maximum of 29 weeks' salary upon
termination without cause and upon the execution by the employee of a release
of all claims against the Company. Under the Employee Separation Plan any
employee (other than below) who is terminated without cause following a change
in control, as defined, would be entitled to receive six months' continuation
of such employee's salary and certain benefits. The Executive Severance Pay
Program covers five senior officers and approximately 55 other key employees
not covered by the Employee Separation Plan and provides severance benefits of
between 1.5 and 3 times the base salary and cash bonus for each such
employee's salary payable upon a change in control, as defined. The
Reorganization (see Note 13) will constitute a change in control.
 
  In September 1996, the Company adopted a plan to pay a cash bonus to its
employees who would otherwise have qualified for the grant of stock options
under the Company's Long-Term Stock Investment Plan. Such compensation
totaling $4.8 million was paid in October 1996 in lieu of stock options.
 
(12) COMMITMENTS AND CONTINGENCIES:
 
  Orbital control of satellites in service is maintained by various service
providers under long-term TT&C agreements totaling approximately $66.8
million. Total annual TT&C costs for satellites in service is approximately
$5.2 million per year. TT&C costs are included in Engineering and Technical
Services and are generally expensed on a straight-line basis over the term of
the agreement.
 
  The Company has commitments for operating leases primarily relating to
equipment and its executive office facilities in Greenwich, Connecticut. These
leases contain escalation provisions for increases in rental due to increased
real estate taxes and operating expenses. Minimum annual rentals of all
leases, exclusive of increases in real estate taxes and operating assessments,
are as follows:

  Total rent expense approximated $1,009,000, $825,000 and $546,000 for the
years ended December 31, 1996, 1995 and 1994, respectively.
 
  In March 1996, Comsat Corporation ("Comsat") initiated an action seeking
compensatory damages of $250 million and unspecified punitive damages against
the Company, Televisa and News Corp. The complaint alleges that the Company
interfered with the alleged termination, by News Corp., of an alleged contract
between Comsat and News Corp. Although the Company believes this action is
without merit and intends to vigorously contest this matter, it is unable to
predict the final outcome of this action at this time.
 
(13) AGREEMENT AND PLAN OF REORGANIZATION:
 
  On September 20, 1996 (the "Announcement Date"), the Company and Hughes
Electronics Corporation ("Hughes") announced their agreement to combine their
respective satellite service operations (the "Combination") into a new
publicly held company ("New PanAmSat"). Under the terms of the Agreement and
Plan of Reorganization that was entered into on the Announcement Date, the
Galaxy Business of Hughes will be combined with the Company to form New
PanAmSat. Holders of PanAmSat Common Stock and Class A Common Stock will have
three options to receive payment with respect to their outstanding shares: (a)
one half share of common stock of New PanAmSat and $15 in cash, (b) one share
of common stock of New PanAmSat (subject to proration, as applicable), or (c)
$30 in cash (subject to proration, as applicable). The maximum cash
consideration to be paid to the Company's direct and indirect stockholders
will be equal to $15 multiplied by the number of shares of Common Stock
outstanding and Hughes may elect to limit the number of shares of New PanAmSat
Stock issued to one-half of the number of shares of PanAmSat Common Stock
outstanding at the time. Immediately after the Combination, Hughes will own
71.5% of New PanAmSat unless the Company's direct and indirect stockholders
request more shares of New PanAmSat Common Stock than cash and New PanAmSat
permits additional shares of its common stock to be issued in lieu of cash to
the Company's direct and indirect stockholders. In a separate but related
transaction, New PanAmSat will acquire all of the outstanding shares of
Univisa, Inc., the indirect holder of all of the Class B Common Stock of the
Company, for consideration that is equal in amount and form (subject to
proration, as applicable) to the consideration payable on account of each
share of PanAmSat Common Stock and Class A Common Stock (the "Univisa
Contribution"). Assuming that New PanAmSat pays half stock and half cash as
consideration in the Combination and the Univisa Contribution, immediately
after the Combination, Hughes will own 71.5% of New PanAmSat, unless the
Company's direct and indirect stockholders request more shares of New PanAmSat
Common Stock than cash and New PanAmSat permits additional shares of its
common stock to be issued in lieu of cash to the Company's direct and indirect
stockholders. The Combination requires governmental approval of the U.S.
Federal Communications Commission which is expected to be received within six
to 12 months of the Announcement Date.
 
  In connection with the above transactions, the Company has incurred certain
professional and advisory fees totaling $4.8 million for the year ended
December 31, 1996. The Company expects these fees will aggregate approximately
$20 million, with the majority of the remaining fees payable upon the
successful completion of the Combination. The Reorganization Agreement
includes termination provisions which require that, in the event that the
Reorganization Agreement is terminated by the Company, and the Company
consummates or agrees to consummate certain business combination transactions,
PanAmSat will pay $80 million to Hughes Communications, Inc.

                         INDEPENDENT AUDITORS' REPORT
 
The Galaxy Business of Hughes Communications, Inc.:
 
  We have audited the accompanying balance sheet of the Galaxy Business of
Hughes Communications, Inc. ("Galaxy") as of December 31, 1996 and 1995 and
the related statements of income and parent company's net investment and of
cash flows for each of the three years in the period ended December 31, 1996.
These financial statements are the responsibility of Galaxy's management. Our
responsibility is to express an opinion on the financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, such financial statements present fairly, in all material
respects, the financial position of Galaxy at December 31, 1996 and 1995 and
the results of its operations and its cash flows for each of the three years
in the period ended December 31, 1996 in conformity with generally accepted
accounting principles.

                 YEARS ENDED DECEMBER 31, 1996, 1995, AND 1994
                                (IN THOUSANDS)
 
1. GENERAL INFORMATION
 
  Basis of Presentation and Description of Business--The financial statements
relate to the Galaxy Business of Hughes Communications, Inc. ("HCI")
("Galaxy") which consists of the operations of several related entities owned
by HCI, itself a wholly owned subsidiary of Hughes Electronics Corporation
("HE"or the "parent company"). The accompanying financial statements have been
derived from the historical financial statements of HCI based on assumptions
management believes represent a reasonable basis for presenting the results of
operations and financial position of Galaxy and include allocations of HE and
HCI corporate expenses. Corporate expenses have been systematically allocated
to Galaxy based primarily on three factors: total revenues, gross payroll and
certain tangible assets. Management believes that this allocation methodology
is reasonable and that the allocated costs are comparable to those which
Galaxy would have incurred on a stand-alone basis. The financial information
included herein may not necessarily reflect the financial position and results
of operations of Galaxy in the future.
 
  Galaxy is a leading provider of commercial satellite services in the United
States. Galaxy offers satellite transponder capacity to cable television
programmers, broadcast television programmers, business communications
customers and direct-to-home ("DTH") service providers, for video, audio and
data communications applications. Galaxy operates a fleet of ten commercial
geostationary fixed service satellites, nine of which primarily serve the
United States and one of which serves both the United States and Latin
America. Galaxy also provides satellite telemetry, tracking, and control
("TT&C") services for its own satellite fleet as well as for other satellites
owned by DIRECTV, Inc., PanAmSat and American Mobile Satellite Corporation.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Use of Estimates in the Preparation of the Financial Statements--The
preparation of the financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect amounts reported therein. Due to the inherent uncertainty involved
in making estimates, actual results reported in future periods may be based
upon amounts which differ from those estimates.
 
  Revenue Recognition--Revenues are generated from outright sales, sales-type
lease and operating lease contracts with customers to provide satellite
transponders, transponder capacity and related services.
 
  Pursuant to an outright transponder sale contract, all rights and title to a
transponder may be purchased. In connection with an outright sale, Galaxy
recognizes the sales amount as revenue and the cost basis of the transponder
is removed and charged to cost of sales. Contracts for sales of transponders
include a TT&C service agreement with Galaxy.
 
  Lease contracts qualifying for capital lease treatment (typically based on
the term of the lease) are accounted for as sales-type leases. For sales-type
lease transactions related to completed satellite transponders, at the time
that a customer enters into a sales-type lease, Galaxy recognizes as revenue
the net present value of the future minimum lease payments. The cost basis of
the transponder is removed and charged to cost of sales. During the life of
the lease, Galaxy recognizes as revenues in each respective period that
portion of each periodic lease payment deemed to be attributable to interest
income. The balance of each periodic lease payment represents principal
repayment and is recognized as a reduction of net investment in sales-type
leases. Interest income from sales-type leases of $41 million, $27 million and
$14 million is included in sales-type lease revenues for the years ended
December 31, 1996, 1995, and 1994.

<PAGE>
 
              THE GALAXY BUSINESS OF HUGHES COMMUNICATIONS, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  For satellite transponders under construction which have been sold outright
or where a sales-type lease has been signed, revenues are recognized using the
percentage-of-completion method based on costs incurred.
 
  Lease contracts that do not qualify as sales-type leases are accounted for
as operating leases. Operating lease revenues are recognized on a straight-
line basis over the lease terms. Differences between operating lease payments
received and revenues recognized are deferred and included in operating lease
receivables.
 
  Revenues related to service agreements and video time-sharing are recognized
as services are rendered.
 
  Galaxy has entered into agreements for the sale and leaseback of certain of
its satellite transponders. Gains resulting from such transactions are
deferred and amortized over the leaseback period. The leaseback transactions
have been classified as operating leases and, therefore, the cost and
associated depreciation related to the satellite transponders sold are not
included in the accompanying financial statements. Leaseback expense is
recorded using the straight-line method over the term of the lease, net of the
amortization of the deferred gains. Differences between operating leaseback
payments made and expense recognized are deferred and included in accrued
operating leaseback expense.
 
  Satellites and Other Property and Equipment and Depreciation--Satellites and
other property and equipment are carried at cost. Satellite costs include
construction costs, launch costs, launch insurance, and capitalized interest.
Expenditures for satellites under construction include manufacturing, launch
and launch insurance progress payments, and capitalized interest amounts.
Depreciation is computed generally using the straight-line method over the
estimated useful lives of the assets, generally 12 years for satellite
transponders and 5 to 18 years for other property and equipment.
 
  Intangible Assets--Effective December 31, 1985, General Motors Corporation
("GM") acquired Hughes Aircraft Company ("HAC"), now a wholly owned subsidiary
of HE. The acquisition of HAC was accounted for as a purchase. The excess of
the purchase price over the net tangible assets acquired, $4,245 million, was
assigned to intangible assets, primarily goodwill. The portion of such
intangible assets and related amortization attributable to Galaxy has been
reflected in the accompanying financial statements.
 
  Intangible assets are amortized using the straight-line method, primarily
over 40 years. Recoverability is periodically evaluated by assessing whether
the unamortized carrying amount can be recovered over its remaining life
through undiscounted cash flows generated by underlying tangible assets.
 
  Deferred Revenues--Galaxy enters into agreements with many of its customers
under which the customers make prepayments for TT&C services to be rendered
over a specified period. Payments received are deferred and amortized over the
periods of performance.
 
  In-Orbit Performance Insurance--Galaxy accrues obligations for the present
value of estimated in-orbit performance insurance costs on transponder sales,
sales-type leases and other agreements with performance warranty provisions,
concurrently with the recognition of the related revenue.
 
  Galaxy also purchases insurance for its owned satellite transponders.
Premiums paid relative to such insurance are amortized to expense over the
insurance policy terms, which are typically one year.
 
  Income Taxes--Galaxy, along with other HE subsidiaries, joins with GM in
filing a consolidated U.S. federal income tax return. Current and deferred
income taxes are computed by HE and allocated to Galaxy according to
principles established by Statement of Financial Accounting Standards (SFAS)
No. 109, "Accounting for Income Taxes." Deferred income tax assets and
liabilities reflect the impact of temporary differences between the amounts of
assets and liabilities recognized for financial reporting purposes and such
 
                                    FIN-25
<PAGE>
 
              THE GALAXY BUSINESS OF HUGHES COMMUNICATIONS, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
amounts recognized for tax purposes, as measured by applying currently enacted
tax laws. HE has paid Galaxy's share of the consolidated income tax liability.
The income taxes that would have been paid by Galaxy if it were a separate
taxpayer but were not paid under HE's policy result in an increase in the
parent company's net investment.
 
  Fair Value of Financial Instruments--The carrying amounts of cash, operating
lease and sale receivables, accounts payable and accrued liabilities
approximate their fair values generally due to the short maturity of these
items. The carrying amount of the net investment in sales-type leases
approximates its fair value because the interest rates implicit in the leases
approximate current market rates.
 
  Concentration of Credit Risk--Galaxy provides satellite transponders and
related services and extends credit to a large number of customers in the
commercial satellite communications market. Management monitors its exposure
to credit losses and maintains allowances for anticipated losses which are
charged to selling, general and administrative expenses.
 
  Accounting Change--Effective January 1, 1996, Galaxy adopted SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to Be Disposed Of." This Statement established accounting standards for the
impairment of long-lived assets, certain identifiable intangibles, and
goodwill related to those assets to be held and used, and for long-lived
assets and certain identifiable intangibles to be disposed of. Adoption of
this Statement did not have a material effect on Galaxy's operating results or
financial position.
 
  Reclassifications--Certain reclassifications have been made to conform to
the current presentation.

  In February 1996, Galaxy entered into a sale and leaseback of certain
satellite transponders on Galaxy III-R with General Motors Acceptance
Corporation ("GMAC"), a subsidiary of GM. Proceeds from the sale were $252
million and resulted in a gain of $109 million, which was deferred and is
being amortized over the seven-year leaseback period. The transponders on
Galaxy III-R are currently under month-to-month subleases pending the planned
conversion of the satellite from international to domestic service in late
1997. Accordingly, there are no sublease payments on these transponders in the
table below. In 1991 and 1992, Galaxy entered into agreements for the sales
and leasebacks of certain transponders on SBS-6 and Galaxy VII, respectively,
resulting in deferred gains of $96 million in 1991 and $180 million in 1992,
which are being amortized over the leaseback periods. The transponder
leaseback terms include early buy out options as follows: $152 million in 1998
and $366 million in 1999. As of December 31, 1996, the future minimum lease
amounts payable to lessors under the operating leasebacks and the future
minimum payments due from sublessees under noncancelable subleases are as
follows:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
  Imputed interest was charged to Galaxy based on net operating assets. During
the years ended December 31, 1996, 1995, and 1994, Galaxy capitalized interest
costs of $14.6 million, $10.1 million, and $5.1 million, respectively, as part
of the cost of its satellites under construction.
 
6. COMMITMENTS AND CONTINGENCIES
 
  Galaxy is subject to potential liability under various claims and legal
actions which are pending or may be asserted against it. The aggregate
ultimate liability of Galaxy under these claims and actions was not
determinable at December 31, 1996. In the opinion of Galaxy's management, such
liability is not expected to have a material adverse effect on Galaxy's
operations or financial position.
 
  From July 1, 1996 through closing of the agreement described in Note 9,
Galaxy, as part of HCI and HE, is obligated under such agreement to fund
additional capital expenditures of approximately $575 million for the
construction and launch of various Galaxy spacecraft. At December 31, 1996
$419 million of this funding requirement remained.
 
7. INCOME TAXES
 
  The income tax provision consisted of the following:

8. RETIREMENT AND INCENTIVE PLANS
 
  Galaxy's employees participate in contributory and non-contributory defined
benefit retirement plans maintained by HE. These plans are available to
substantially all full-time employees. Benefits are based on years of service
and compensation earned during a specified period of time before retirement.
The accumulated plan benefit obligations and plan net assets for the employees
of the Business have not been separately determined and are not included in
Galaxy's balance sheet. In addition to pension benefits, HE charges Galaxy its
allocated share of employee-related postretirement benefit costs. The
accumulated postretirement benefit obligation related to Galaxy's employees
has not been separately determined and is not included in the balance sheet.
Galaxy's employees also participate in other HE health and welfare plans.
Charges related to these plans, included in the statements of income, were not
significant for the years ended December 31, 1996, 1995, and 1994.
 
9. AGREEMENT AND PLAN OF REORGANIZATION
 
  On September 20, 1996 (the "Announcement Date"), HE and PanAmSat Corporation
announced their agreement to combine their respective satellite service
operations (the "Combination") into a new publicly held company ("New
PanAmSat"). Under the terms of the Agreement and Plan of Reorganization that
was entered into on the Announcement Date, Galaxy will be combined with
PanAmSat to form New PanAmSat. Holders of PanAmSat Common Stock and PanAmSat
Class A Common Stock will have three options to receive payment with respect
to their outstanding shares: (a) one-half share of common stock of New
PanAmSat and $15 in cash, (b) one share of common stock of New PanAmSat
(subject to proration, as applicable) or (c) $30 in cash (subject to proration
as applicable). The maximum cash consideration to be paid to PanAmSat's direct
and indirect stockholders will be equal to $15 multiplied by the number of
shares of PanAmSat Common Stock outstanding and HE may elect to limit the
number of shares of New PanAmSat Stock issued to one-half of the number of
shares of PanAmSat Common Stock outstanding at the time. Immediately after the
Combination, HE will own 71.5% of New PanAmSat unless the direct and indirect
holders of PanAmSat Common Stock request more shares of New PanAmSat common
stock than cash and New PanAmSat permits additional shares of its common stock
to be issued in lieu of cash to PanAmSat's direct and indirect stockholders.
In a separate but related transaction, New PanAmSat will acquire all of the
outstanding shares of Univisa, Inc., the indirect holder of all of PanAmSat's
Class B Common Stock, for consideration that is equal in amount and form
(subject to proration, as applicable) to that being paid to the holders of
PanAmSat Common Stock and PanAmSat Class A Common Stock. The Combination
requires governmental approval of the U.S. Federal Communications Commission
which is expected to be received within 6 to 12 months of the Announcement
Date.

owned subsidiary formed for the purposes of effecting a merger with PanAmSat
Corporation.
 
2. AGREEMENT AND PLAN OF REORGANIZATION
 
  On September 20, 1996 (the "Announcement Date"), Magellan, HCI and certain
subsidiaries of HCI entered into an agreement pursuant to which HCI and
certain of its subsidiaries will contribute the assets and liabilities of the
Galaxy Business of HCI to Magellan, and PAS Merger Corp., will merge into
PanAmSat Corporation. In connection with the agreement, holders of PanAmSat
Common Stock and PanAmSat Class A Common Stock will have three options to
receive payment with respect to their outstanding shares: (a) one-half share
of common stock of Magellan and $15 in cash, (b) one share of common stock of
Magellan (subject to proration, as applicable), or (c) $30 in cash (subject to
proration, as applicable). The maximum cash consideration to be paid by
Magellan to PanAmSat's direct and indirect stockholders will be equal to $15
multiplied by the number of shares of PanAmSat Common Stock outstanding and HE
may elect to limit the number of shares of Magellan issued to one-half of the
number of shares of PanAmSat Commons Stock outstanding at the time.
Immediately after the combination, HE will own 71.5% of Megellan unless
PanAmSat's stockholders request more shares of Magellan common stock than cash
and Magellan permits additional shares of its common stock to be issued in
lieu of cash to PanAmSat's direct and indirect stockholders. In a separate but
related transaction, Megellan will acquire all of the outstanding shares of
Univisa, Inc., the indirect holder of all of PanAmSat's Class B Common Stock,
for consideration that is equal in amount and form (subject to proration, as
applicable) to that being paid to the holders of PanAmSat Common Stock and
PanAmSat Class A Common Stock. The agreement requires governmental approval of
the U.S. Federal Communications Commission which is expected to be received
within 6 to 12 months of the Announcement Date.

PAS.
 
                                  Article II

equal to the number of shares of, and having terms identical in all respects
to, PAS Common Stock outstanding immediately prior to the Merger.
 
  4.2 Conversion of PAS Shares.
 
  (a) Except as otherwise provided in Section 4.4 and subject to Sections
4.2(c) and 4.2(d), at the Effective Time, each issued and outstanding share,
other than any share owned by Newco or any Subsidiary of Newco, of PAS Common
Stock and Class A Common Stock (collectively, the "Shares") shall be converted
into, at the election of the holder thereof, one of the following (as may be
adjusted pursuant to Sections 4.4 and 4.6, the "Merger Consideration"):
 
    (i) for each such Share with respect to which an election to receive a
  combination of Newco Common Stock and cash has been effectively made and
  not revoked or lost pursuant to Sections 4.3(c), (d) and (e) (a "Standard
  Election"), the right to receive (x) an amount in cash equal to one-half of
  the Standard Cash Consideration plus (y) one-half (0.5) share of Newco
  Common Stock (collectively, the "Standard Consideration"). The "Standard
  Cash Consideration" means an amount in cash equal to thirty dollars
  ($30.00), provided that, if the Closing shall not have occurred on or prior
  to the first anniversary of this Agreement, the Standard Cash Consideration
  shall be increased at a rate equal to 9% per annum from and including the
  first anniversary date to but excluding the Closing Date; or
 
    (ii) for each such Share with respect to which an election to receive
  solely Newco Common Stock has been effectively made and not revoked or lost
  pursuant to Sections 4.3(c), (d) and (e) (a "Stock Election"), the right to
  receive one (1) share of Newco Common Stock (the "Stock Consideration"); or
 
    (iii) for each such Share with respect to which an election to receive
  solely cash has been effectively made and not revoked or lost pursuant to
  Sections 4.3(c), (d) and (e) (a "Cash Election"), the right to receive the
  Standard Cash Consideration.
 
  (b) As a result of the Merger and without any action on the part of the
holder thereof, at the Effective Time, (i) all Shares held by any person other
than Newco (or any Subsidiary of Newco) shall cease to be outstanding and
shall be cancelled and retired and shall cease to exist, and each such holder
of Shares shall thereafter cease to have any rights with respect to such
Shares, except the right to receive, without interest, the Merger
Consideration and cash in lieu of fractional shares of Newco Common Stock in
accordance with Section 4.5(c) upon the surrender of a certificate
representing such Shares (a "Share Certificate") and (ii) all outstanding
shares of Class B Common Stock shall continue to be indirectly held by
Univisa.
 
  (c) Notwithstanding anything contained in this Section 4.2 to the contrary,
each Share issued and held in PAS' treasury immediately prior to the Effective
Time shall, by virtue of the Merger, cease to be outstanding and shall be
cancelled and retired without payment of any consideration therefor.
 
  (d) Notwithstanding anything in this Section 4.2 to the contrary, Shares
which are issued and outstanding immediately prior to the Effective Time and
which are held by stockholders who have not voted such shares in favor of the
Merger and who shall have properly exercised their rights of appraisal for
such shares in the manner provided by the DGCL (the "Dissenting Shares") shall
be deemed to have made a Cash Election for purposes of Section 4.4, but shall
not be converted into or be exchangeable for the right to receive the Merger
 
                                      A-6
<PAGE>
 
Consideration, unless and until such holder shall have failed to perfect or
shall have effectively withdrawn or lost his right to appraisal and payment,
as the case may be. If such holder shall have so failed to perfect or shall
have effectively withdrawn or lost such right, his shares shall thereupon be
deemed to have been converted into and to have become exchangeable for, at the
Effective Time, the right to receive the Standard Consideration, without any
interest thereon. PAS shall give Newco prompt notice of any Dissenting Shares
(and shall also give Newco prompt notice of any withdrawals of such demands
for appraisal rights) and Newco shall have the right to direct all
negotiations and proceedings with respect to any such demands. Neither PAS nor
the corporation surviving the Merger shall, except with the prior written
consent of Newco, voluntarily make any payment with respect to, or settle or
offer to settle, any such demand for appraisal rights.
 
  (e) At the Effective Time, each holder of a then-outstanding option to
purchase Shares under PAS' Long-Term Stock Investment Plan and the Option
Agreements between PAS and certain of its executive officers and other
employees (collectively, the "Stock Option Plans"), whether or not then
exercisable (the "Options"), shall, in settlement thereof, receive for each
Share subject to such Option an amount (subject to any applicable withholding
tax) in cash equal to the difference between (i) the Standard Cash
Consideration and (ii) the per Share exercise price of such Option to the
extent such difference is a positive number (such amount being hereinafter
referred to as, the "Option Consideration"); provided, however, that with
respect to any person subject to Section 16(b) of the Securities Exchange Act
of 1934, as amended, (the "Exchange Act"), any such amount shall be paid as
soon as practicable after the first date payment can be made without liability
to such person under Section 16(b) of the Exchange Act. Upon receipt of the
Option Consideration, the Option shall be canceled. The surrender of an Option
to PAS in exchange for the Option Consideration shall be deemed a release of
any and all rights the holder had or may have had in respect of such Option.
Prior to the Effective Time, PAS shall obtain all necessary consents or
releases from holders of Options under the Stock Option Plans and take all
such other lawful action as may be necessary to give effect to the
transactions contemplated by this Section 4.2(e) (except for any such action
that may require the approval of PAS' stockholders). Except as otherwise
agreed to by the parties, (i) the Stock Option Plans shall terminate as of the
Effective Time and the provisions in any other plan, program or arrangement
providing for the issuance or grant of any other interest in respect of the
capital stock of PAS or any Subsidiary thereof, shall be canceled as of the
Effective Time, and (ii) PAS shall assure that following the Effective Time no
participant in the Stock Option Plans or other plans, programs or arrangements
shall have any right thereunder to acquire equity securities of PAS, the
corporation surviving the Merger or any Subsidiary thereof and to terminate
all such plans.
 
  4.3 Elections by Holders of Shares.
 
  (a) Each person who, at the Effective Time, is a record holder of Shares
(other than holders of Shares to be cancelled as set forth in Section 4.2(c)
or Dissenting Shares) shall have the right to submit an Election Form (as
defined in Section 4.3(c)) specifying the number of Shares that such person
desires to have converted into the right to receive Newco Common Stock and
cash pursuant to the Standard Election, the number of Shares that such person
desires to have converted into the right to receive Newco Common Stock
pursuant to a Stock Election and the number of Shares that such person desires
to have converted into the right to receive cash pursuant to a Cash Election.
 
  (b) Promptly after the Allocation Determination (as defined in Section
4.3(d)), Newco shall deposit (or cause to be deposited) with a bank or trust
company to be designated by HCI and reasonably acceptable to PAS (the
"Exchange Agent"), for the benefit of the holders of Shares and S Company, for
exchange in accordance with this Article IV and the Univisa Contribution
Agreement, (i) cash in the amount sufficient to pay the aggregate cash portion
of the Merger Consideration and the consideration payable in the Univisa
Contribution and (ii) certificates representing the shares of Newco Common
Stock ("Newco Certificates") for exchange in accordance with this Article IV
and the Univisa Contribution Agreement (the cash and shares deposited pursuant
to clauses (i) and (ii) being hereinafter referred to as the "Exchange Fund").
Newco Common Stock into which Shares shall be converted pursuant to the Merger
shall be deemed to have been issued at the Effective Time.
 
 
                                      A-7
<PAGE>
 
  (c) As soon as reasonably practicable after the Effective Time, the Exchange
Agent shall mail to each holder of record of Shares immediately prior to the
Effective Time (excluding any Shares which will be cancelled pursuant to
Section 4.2(c) or Dissenting Shares) (A) a letter of transmittal (the "Letter
of Transmittal") (which shall specify that delivery shall be effected, and
risk of loss and title to Share Certificates shall pass, only upon delivery of
such Share Certificates to the Exchange Agent and shall be in such form and
have such other provisions as Newco shall specify), (B) instructions for use
in effecting the surrender of Share Certificates in exchange for the Merger
Consideration with respect to the Shares formerly represented thereby, and (C)
an election form (the "Election Form") providing for such holders to make the
Standard Election, the Stock Election or the Cash Election. As of the Election
Deadline (as defined in Section 4.3(d)), all holders of Shares immediately
prior to the Effective Time that shall not have submitted to the Exchange
Agent or shall have properly revoked an effective, properly completed Election
Form shall be deemed to have made a Standard Election.
 
  (d) Any Standard Election, Stock Election or Cash Election shall have been
validly made only if the Exchange Agent shall have received by 5:00 p.m. New
York time on a date (the "Election Deadline") to be mutually agreed upon by
HCI, Newco and PAS, an Election Form properly completed and executed (with the
signature or signatures thereof guaranteed to the extent required by the
Election Form) by such holder accompanied by such holder's Share Certificates,
or by an appropriate guarantee of delivery of such Share Certificates from a
member of any registered national securities exchange or of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company
in the United States as set forth in such Election Form. Any holder of Shares
who has made an election by submitting an Election Form to the Exchange Agent
may, at any time prior to the Election Deadline, change such holder's election
by submitting a revised Election Form, properly completed and signed that is
received by the Exchange Agent prior to the Election Deadline. Any holder of
PAS Common Stock may at any time prior to the Election Deadline revoke his
election and withdraw his Share Certificates deposited with the Exchange Agent
by written notice to the Exchange Agent received by the close of business on
the day prior to the Election Deadline. As soon as practicable after the
Election Deadline, the Exchange Agent shall determine the allocation of the
cash portion of the Merger Consideration and the stock portion of the Merger
Consideration and shall notify Newco of its determination (the "Allocation
Determination").
 
  (e) Upon surrender of a Share Certificate for cancellation to the Exchange
Agent, together with the Letter of Transmittal duly executed, and such other
documents as Newco or the Exchange Agent shall reasonably request, the holder
of such Share Certificate shall be entitled to receive promptly after the
Allocation Determination in exchange therefor (A) a certified or bank
cashier's check in the amount equal to the cash, if any, which such holder has
the right to receive pursuant to the provisions of this Article IV (including
any cash in lieu of fractional shares of Newco Common Stock pursuant to
Section 4.5(c)), and (B) a Newco Certificate representing that number of
shares of Newco Common Stock, if any, which such holder has the right to
receive pursuant to this Article IV (in each case less the amount of any
required withholding taxes), and the Share Certificate so surrendered shall
forthwith be cancelled. Until surrendered as contemplated by this Section
4.3(e), each Share Certificate shall be deemed at any time after the Effective
Time to represent only the right to receive the Merger Consideration with
respect to the Shares formerly represented thereby.
 
  (f) Newco shall have the right to make reasonable rules, not inconsistent
with the terms of this Agreement, governing the validity of the Election
Forms, the manner and extent to which Standard Elections, Stock Elections or
Cash Elections are to be taken into account in making the determinations
prescribed by Section 4.4, the issuance and delivery of certificates for Newco
Common Stock into which Shares are converted in the Merger, and the payment of
cash for Shares converted into the right to receive cash in the Merger.
 
  (g) Notwithstanding the foregoing provisions of this Section 4.3, the
parties hereto may decide to distribute Election Forms to PAS' stockholders
and require that holders making such elections respond prior to the Merger,
upon such additional terms and conditions as may be agreed to by the parties.

  4.4 Proration.
 
  (a) As is more fully set forth below and except as may be paid pursuant to
Section 4.5 or otherwise in respect of Dissenting Shares, the aggregate amount
of cash to be paid in the Merger and in the Univisa Contribution (other than
the cash payment of $225 million provided for in the last sentence of Section
1.2(a) of the Univisa Contribution Agreement) shall not exceed the product of
(x) one-half ( 1/2) of the Standard Cash Consideration and (y) the aggregate
number of shares of PAS Common Stock, Class A Common Stock and Class B Common
Stock issued and outstanding immediately prior to the Effective Time (such
product, the "Maximum Cash Amount").
 
  (b) In the event that the sum of the aggregate amount of cash represented by
the Cash Elections hereunder (including Cash Elections deemed to have been
made with respect to Dissenting Shares) and under the Univisa Contribution
Agreement received by the Exchange Agent (such sum, the "Requested Cash
Amount") exceeds the Maximum Cash Amount minus the aggregate amount of cash
payable on account of all Standard Elections made or deemed to have been made
hereunder or under the Univisa Contribution Agreement (such difference, the
"Cash Cap"), each holder making (or deemed to make) a Cash Election hereunder
or under the Univisa Contribution Agreement shall receive, for each Share or
Value Unit (as such term is defined in the Univisa Contribution Agreement), as
the case may be, with respect to which a Cash Election has been made (or is
deemed to have been made) hereunder or under the Univisa Contribution
Agreement, (x) cash in an amount equal to the Prorated Cash Amount and (y) a
number of shares of Newco Common Stock equal to a fraction, the numerator of
which is equal to the Standard Cash Consideration minus the Prorated Cash
Amount and the denominator of which is the Standard Cash Consideration. The
term "Prorated Cash Amount" means the greater of (i) one-half ( 1/2) of the
Standard Cash Consideration and (ii) the product of the Standard Cash
Consideration and a fraction, the numerator of which is the Cash Cap and the
denominator of which is the Requested Cash Amount.
 
  (c) The aggregate number of shares of Newco Common Stock that may be issued
pursuant to Stock Elections hereunder and under the Univisa Contribution
Agreement is not subject to any maximum. In the event that the Requested Cash
Amount is less than the Cash Cap, each holder making a Stock Election
hereunder or under the Univisa Contribution Agreement shall receive, at the
option of Newco, for each Share or Value Unit, as the case may be, with
respect to which a Stock Election has been made hereunder or under the Univisa
Contribution Agreement, (x) not more than the Stock Consideration and not less
than a number of shares of Newco Common Stock equal to a fraction the
numerator of which is the Requested Stock Amount minus the difference between
the Cash Cap and the Requested Cash Amount, and the denominator of which is
the Requested Stock Amount (such whole or fractional share, the "Prorated
Stock Amount") and (y) cash in an amount equal to the product of (A) the
Standard Cash Consideration and (B) one minus the Prorated Stock Amount. The
term "Requested Stock Amount" means the product of the aggregate number of
shares of Newco Common Stock represented by Stock Elections hereunder or under
the Univisa Contribution Agreement received by the Exchange Agent and the
Standard Cash Consideration.
 
  4.5 Dividends, Fractional Shares, Etc.
 
  (a) Notwithstanding any other provisions of this Agreement, no dividends or
other distributions declared after the Effective Time on Newco Common Stock
shall be paid with respect to any Shares which, prior to the Effective Time,
were represented by a Share Certificate until such Share Certificate is
surrendered for exchange as provided herein. Subject to the effect of
applicable Laws (as defined in Section 5.6(a)), following surrender of any
such Share Certificate, there shall be paid to the holder of the Newco
Certificates issued in exchange therefor, without interest, (i) at the time of
such surrender, the amount of dividends or other distributions with a record
date after the Effective Time theretofore payable with respect to such whole
shares of Newco Common Stock and not paid, less the amount of any withholding
taxes which may be required thereon, and (ii) at the appropriate payment date,
the amount of dividends or other distributions with a record date after the
Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole shares of Newco Common Stock,
less the amount of any withholding taxes which may be required thereon.
 
                                      A-9
<PAGE>
 
  (b) At or after the Effective Time, there shall be no transfers on the stock
transfer books of PAS of the Share Certificates which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
certificates formerly representing any such Shares are presented to the
surviving corporation in the Merger, they shall be cancelled and exchanged for
certificates for the consideration, if any, deliverable in respect thereof
pursuant to this Agreement in accordance with the procedures set forth in this
Article IV. Share Certificates surrendered for exchange by any person
constituting an "affiliate" of PAS for purposes of Rule 145(c) under the
Securities Act of 1933, as amended (the "Securities Act"), shall not be
exchanged until Newco has received a written agreement from such person as
provided in Section 7.14.
 
  (c) No fractional shares of Newco Common Stock shall be issued pursuant to
the Merger or the Univisa Contribution. In lieu of the issuance of any
fractional share of Newco Common Stock pursuant to the Merger or the Univisa
Contribution, cash adjustments will be paid to holders in respect of any
fractional share of Newco Common Stock that would otherwise be issuable, and
the amount of such cash adjustment shall be equal to the product of such
fractional amount and the Standard Cash Consideration.
 
  (d) Any portion of the Exchange Fund (including the proceeds of any
investments thereof and any shares of Newco Common Stock) that remains
unclaimed by the former stockholders of PAS six months after the Effective
Time shall be delivered to Newco. Any former stockholder of PAS who has not
theretofore complied with this Article IV shall thereafter look only to Newco
for payment of the consideration payable on account of the Univisa
Contribution or the Merger, as the case may be, cash in lieu of fractional
shares and unpaid dividends and distributions on the Newco Common Stock
deliverable in respect of each share such stockholder holds as determined
pursuant to this Agreement, in each case without any interest thereon.
 
  (e) None of HCI, its Affiliates, PAS, Newco, the Exchange Agent or any other
person shall be liable to any former holder of Shares or shares of Class B
Common Stock for any amount properly delivered to a public official pursuant
to applicable abandoned property, escheat or similar laws.
 
  (f) In the event that any Share Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Share Certificate to be lost, stolen or destroyed and, if required by
Newco, the posting by such person of a bond in such reasonable amount as Newco
may direct as indemnity against any claim that may be made against it with
respect to such Share Certificate, the Exchange Agent will issue in exchange
for such lost, stolen or destroyed Share Certificate the applicable Merger
Consideration, cash in lieu of fractional shares, and unpaid dividends and
distributions on Shares as provided in this Section 4.5, deliverable in
respect thereof pursuant to this Agreement.
 
  4.6 Certain Additional Prorations. In the event that the aggregate number of
shares of Newco Common Stock for which Value Units were to be exchanged
pursuant to Section 1.2(a) of the Univisa Contribution Agreement would
otherwise be less than seven million five hundred thousand (7,500,000) (after
giving effect to any prorations pursuant to Section 4.4, if applicable), then
notwithstanding anything to the contrary contained in this Agreement or in the
Univisa Contribution Agreement, (i) a number of Value Units equal to seven
million five hundred thousand (7,500,000) minus the aggregate number of shares
of Newco Common Stock for which Value Units would otherwise be exchanged
pursuant to Section 1.2(a) of the Univisa Contribution Agreement (after giving
effect to any prorations pursuant to Section 4.4, if applicable) (such
difference, the "SPOT Difference") shall be exchanged for Newco Common Stock
(after giving effect to any prorations pursuant to Section 4.4, if
applicable), (ii) the aggregate amount of cash for which Value Units were
otherwise to be exchanged pursuant to Section 1.2(a) of the Univisa
Contribution Agreement (after giving effect to any prorations pursuant to
Section 4.4, if applicable) shall be reduced by an amount equal to the product
of the SPOT Difference and the Standard Cash Consideration, and (iii) the
aggregate number of Shares with respect to which Cash Elections or Stock
Elections were made hereunder shall be adjusted in accordance with Section
4.4, if applicable, giving effect (a) first, to the Shares as to which a Cash
Election was made but which were to be converted into the right to receive
shares of Newco Common Stock in lieu of cash in accordance with Section
4.4(b), and (b) second, to all other Shares as to which a Stock Election was
made.

                                   Article V
 
                     Representations and Warranties of PAS
 
  PAS represents and warrants to each of the Hughes Parties as follows:
 
  5.1 Organization, Standing and Power. Each of PAS and its Subsidiaries is a
corporation duly organized, validly existing and in good standing under the
laws of its respective jurisdiction of incorporation, has all requisite
corporate power and authority necessary to own, lease and operate its
properties and to carry on its business as now being conducted, and is duly
qualified, and in good standing to own, lease and operate its properties and
to conduct business in each jurisdiction, domestic and foreign, in which the
business it is conducting, or the operation, ownership or leasing of its
properties, makes such qualification necessary, other than in such
jurisdictions where the failure to so qualify or be in good standing is not
likely to have a material adverse effect on PAS and its Subsidiaries, taken as
a whole. PAS and each of its Subsidiaries has heretofore made available to HCI
true, complete and correct copies of its Certificate of Incorporation and
Bylaws as currently in effect together with all amendments thereto. No
resolution has been adopted to amend any of such Certificates of Incorporation
or Bylaws except as expressly called for by this Agreement. None of PAS or its
Subsidiaries (i) has been dissolved, adopted resolutions to dissolve or acted
in any way to accomplish, request or approve such dissolution, (ii) is a party
to any merger or (iii) has been declared bankrupt, and, to PAS' knowledge, no
action or request is pending to declare it bankrupt. PAS has made available to
HCI minute books for each of PAS and its Subsidiaries which contain complete
and accurate records in all material respects of all meetings, or consents in
lieu thereof, of the stockholders and the Board of Directors (including
committees thereof) of each such entity since its date of formation. As used
in this Agreement, any reference to any event, change or effect having a
"material adverse effect" on any person or entity means (i) such event, change
or effect, individually or in the aggregate with other events, changes, or
effects, is materially adverse to the financial condition, business, results
of operations, assets, liabilities, properties or prospects of such person or
entity and (ii) such event, change or effect, individually, or in the
aggregate with other events, changes or effects, would impair the right or
ability of the parties hereto and thereto to consummate the transactions
contemplated hereby and by the Related Agreements (as defined in Section 7.9).
 
  5.2 Capital Structure. As of the date hereof, the authorized capital stock
of PAS consists of 100,000,000 shares of Class A Common Stock, 100,000,000
shares of Class B Common Stock, 400,000,000 shares of PAS Common Stock and
20,000,000 shares of Preferred Stock, $.01 par value per share ("PAS Preferred
Stock"). At the close of business on September 1, 1996: (i) 40,459,432 shares
of Class A Common Stock, 40,459,431 shares of Class B Common Stock, 19,081,137
shares of PAS Common Stock and 311,132.777 shares of PAS Preferred Stock were
issued and outstanding, 1,065,225 shares of PAS Common Stock were reserved for
issuance pursuant to currently outstanding options pursuant to the Stock
Option Plans, and, except for the issuance of shares of PAS Common Stock
pursuant to the exercise of the Options and except as set forth on Schedule
5.2, there are no employment, executive termination or similar agreements
providing for the issuance of any shares of Class A Common Stock, Class B
Common Stock, PAS Common Stock or PAS Preferred Stock; (ii) no shares of Class
A Common Stock, Class B Common Stock, PAS Common Stock or PAS Preferred Stock
were held by PAS or any of its Subsidiaries; and (iii) except as set forth on
Schedule 5.2, no bonds, debentures, notes or other instruments or evidence of
indebtedness having the right to vote (or convertible into, or exercisable or
exchangeable for, securities having the right to vote) on any matters on which
stockholders of PAS may vote ("PAS Voting Debt") were issued or outstanding.
All outstanding shares of the capital stock of PAS and the outstanding capital
stock of each of PAS' Subsidiaries and all such shares which may be issued
upon the exercise of outstanding options and warrants are validly issued,
fully paid and nonassessable and no such shares are subject to preemptive or
other similar rights. Except as set forth on Schedule 5.2, all outstanding
shares of capital stock of PAS' Subsidiaries are owned by PAS or a direct or
indirect wholly-owned Subsidiary of PAS, free and clear of all liens, charges,
encumbrances, claims and options of any nature. Except as set forth on
Schedule 5.2, neither PAS nor any of PAS' Subsidiaries (i) beneficially owns
any capital shares or has any other record or beneficial equity or other
ownership or interest in any corporation, partnership, joint venture,
association or other entity or business enterprise or (ii) has any commitment
to contribute to the capital of, make loans to, or share the losses of any
 
                                     A-11
<PAGE>
 
person or entity (other than any of PAS or any of its Subsidiaries). Except as
set forth in this Section 5.2 and except for changes since September 1, 1996
resulting from the exercise of stock options granted pursuant to the Stock
Option Plans, there are outstanding: (i) no shares of capital stock, PAS
Voting Debt or other voting securities of PAS authorized, issued or
outstanding; (ii) no securities of PAS or any Subsidiary of PAS convertible
into, or exchangeable or exercisable for, shares of capital stock, PAS Voting
Debt or other voting securities of PAS or any Subsidiary of PAS; and (iii) no
options, warrants, calls, rights (including preemptive rights), commitments or
agreements to which PAS or any Subsidiary of PAS is a party or by which it is
bound, in any case obligating PAS or any Subsidiary of PAS to issue, deliver,
sell, purchase, redeem or acquire, or cause to be issued, delivered, sold,
purchased, redeemed or acquired, additional shares of capital stock of PAS or
any PAS Voting Debt or other voting securities of PAS or of any Subsidiary of
PAS, or obligating PAS or any Subsidiary of PAS to grant, extend or enter into
any such option, warrant, call, right, convertible security, commitment or
agreement. Since September 1, 1996, PAS has not (i) granted any options,
warrants or rights to purchase shares of capital stock of PAS or (ii) amended
or repriced any Option or the Stock Option Plans, and set forth on Schedule
5.2 is a list of all outstanding options, warrants and rights to purchase
shares of capital stock of PAS and the exercise prices relating thereto.
Except as set forth on Schedule 5.2, there are not as of the date hereof and
there will not be at the Effective Time any stockholder agreements, voting
trusts or other agreements or understandings to which PAS or any of its
Subsidiaries is a party or by which any such entity is bound relating to the
voting of any shares of the capital stock of PAS or any of its Subsidiaries.
Except as set forth on Schedule 5.2, there are no restrictions on PAS to vote
the stock of any of its Subsidiaries. Except as granted in connection with the
transactions contemplated by this Agreement, no person has any rights to cause
PAS or its Subsidiaries to register with the United States Securities and
Exchange Commission (the "SEC") any securities of PAS or any of its
Subsidiaries.
 
  5.3 Authority; No Violations; Consents and Approvals.
 
  (a) PAS has all requisite corporate power and authority to execute and
deliver this Agreement and the Related Agreements to which it is a party and
to perform its obligations hereunder and thereunder and to effect the
transactions contemplated hereby and thereby, and subject to PAS Stockholder
Approval (as defined in Section 5.3(c)), to consummate the transactions
contemplated hereby. The execution, delivery and performance of this Agreement
and the Related Agreements to which PAS is a party and the consummation of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of PAS, subject, if required with
respect to consummation of the Merger, to PAS Stockholder Approval. Each of
this Agreement and the Related Agreements to which PAS is a party has been
duly executed and delivered by PAS and, subject, if required with respect to
consummation of the Merger, to PAS Stockholder Approval, and assuming that
each of this Agreement and the Related Agreements to which PAS is a party
constitutes the valid and binding agreement of the other parties thereto, and
subject to obtaining all necessary approvals by Government Entities,
constitutes a valid and binding obligation of PAS enforceable in accordance
with its terms except that the enforcement hereby may be limited by (a)
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or
other similar laws now or hereafter in effect relating to creditors' rights
generally and (b) general "principles of equity" (regardless of whether
enforceability is considered in a proceeding at law or in equity) (the
foregoing exception, the "Bankruptcy Exception"). For purposes of this
Agreement, the term "Government Entity" means any legislative, executive,
judicial, regulatory or other governmental or quasi-governmental authority,
instrumentality or body, whether domestic or foreign, local, state, federal or
other, including, without limitation, any administrative agency, commission or
court.
 
  (b) The execution, delivery and performance by PAS of each of this Agreement
and the Related Agreements to which PAS is a party does not, and the
consummation by PAS of the transactions contemplated hereby and thereby will
not, (x) conflict with, or result in any violation of, or default (with or
without notice or lapse of time, or both) which is likely to have a material

a right of termination, cancellation or acceleration of any obligation or the

refusal, a "PAS Violation"), under or pursuant to any provision of the
respective Certificate of Incorporation or Bylaws of PAS or equivalent
constituent document of any of its Subsidiaries or, (y) except as to which
requisite waivers or consents have been obtained and, except as set forth on
Schedule 5.3(b) hereto and assuming the consents, approvals, authorizations or
permits and filings or notifications referred to in paragraph (c) of this
Section 5.3 are duly and timely obtained or made and, if required, PAS
Stockholder Approval is obtained, result in any PAS Violation of any Material
Contract, PAS ERISA Plan (as defined in Section 5.9(c)(i)), PAS Benefit
Arrangement (as defined in Section 5.9(c)(ii)), PAS Permit (as defined in
Section 5.6(b)), or Law applicable to PAS or any of its Subsidiaries or any of
their respective properties or assets; provided, however, that nothing in this
Section 5.3 will be deemed to constitute a representation or warranty by PAS
as to any antitrust law or requirement. The Board of Directors of PAS has
taken all actions necessary under the DGCL, including approving the
transactions contemplated by this Agreement and the Related Agreements, to
ensure that Section 203 of the DGCL and the provisions of any other state
takeover laws do not, and will not, apply to the transactions contemplated
hereby and thereby. No vote of the holders of the PAS Preferred Stock is
required to consummate the Asset Contribution, the Univisa Contribution, the
Merger or any of the other transactions contemplated hereby.
 
  (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, notice to, or permit from any Government Entity,
is required by or with respect to PAS or any of its Subsidiaries in connection
with the execution and delivery by PAS of any of this Agreement or the Related
Agreements to which PAS is a party or the consummation by PAS of the
transactions contemplated hereby and thereby, which if not obtained or made is
likely to have a material adverse effect on PAS' ability to consummate the
transactions contemplated hereby and thereby, except for: (A) the filing of a
premerger notification and report form by PAS under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, and the rules and regulations
thereunder (the "HSR Act") and the expiration or termination of the applicable
waiting period thereunder; (B) the filing with the SEC of (x) the Proxy
Statement/Prospectus and related Registration Statement (as such terms are
defined in Section 7.5) relating to a meeting of the holders of shares of
common stock of PAS to adopt this Agreement (the "PAS Stockholder Approval")

approvals, orders, authorizations and filings required under any
environmental, health or safety law; (G) the filing with the FCC of (x) the
applications and waiver requests described in Section 7.9(c), (y) any

associated filings with the FCC that do not require the FCC's consent or
approval; and (H) such other consents, approvals, orders, authorizations,
registrations, declarations, filings, notices and Permits (as defined in
Section 5.6(a)) set forth on Schedule 5.3(c).
 
  5.4 SEC Documents. PAS has made available to HCI a true and complete copy of
each form, report, schedule, registration statement and definitive proxy
statement filed by PAS with the SEC since July 29, 1993 and prior to the date
of this Agreement (the "PAS SEC Documents"), which are all the documents
(other than preliminary material) that PAS was required to file with the SEC
since such date. As of their respective dates, or, if required to be amended,
as of the date of the last such amendment, (i) the PAS SEC Documents complied
in all material respects with the requirements of the Securities Act or the
Exchange Act, as the case may be, and the rules and regulations of the SEC
thereunder applicable to such PAS SEC Documents, and (ii) none of the PAS SEC
Documents contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. Each of the financial statements of PAS included in the PAS
SEC Documents have been prepared from, and are in accordance with, the books
and records of PAS and/or its consolidated Subsidiaries, comply in all
material respects with applicable accounting requirements and with the
published
 
                                     A-13
<PAGE>
 
rules and regulations of the SEC with respect thereto, were prepared in
accordance with GAAP applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto) and present fairly, in all
material respects, in accordance with applicable requirements of GAAP, the
consolidated financial position of PAS and its consolidated Subsidiaries as of
their respective dates and the consolidated results of operations and the
consolidated cash flows of PAS and its consolidated Subsidiaries for the
periods presented therein. No Subsidiary of PAS is required to file any form,
report or other document with the SEC. The books and all other financial
records of PAS and each of its Subsidiaries are complete and correct in all
material respects.
 
  5.5 Information Supplied. The Proxy Statement/Prospectus (as defined in
Section 7.5), or any amendment thereof or supplement thereto, will not, on the
date it is first mailed to PAS' stockholders or at the time of PAS'
stockholders meeting, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
are made, not misleading; provided, however, that no representation is made by
PAS with respect to statements made therein based on information supplied by
any Hughes Party for inclusion in the Proxy Statement/Prospectus. The
information supplied by PAS for inclusion in each Registration Statement (as
defined in Section 7.5) will not, on the date it is first filed with the SEC
and as of the date it becomes effective, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. Subject to the
proviso set forth in the second preceding sentence, the Proxy
Statement/Prospectus, will comply as to form, in all material respects, with
the provisions of the Exchange Act and the rules and regulations thereunder.
 
  5.6 Compliance with Laws.
 
  (a) Except as disclosed on Schedule 5.6(a) or the PAS SEC Documents, the
businesses of PAS and its Subsidiaries are not being conducted in violation of
any Law the violation of which is likely to have a material adverse effect on
PAS or any of its Subsidiaries. Except as disclosed on Schedule 5.6(a), no
material investigation or review by any Government Entity with respect to PAS,
any of its Subsidiaries or their respective businesses is pending or, to the
best knowledge of PAS, threatened and PAS has not received any written
citation or notification alleging any violation of any Law or Permit the
continuing violation of which is likely to have a material adverse effect on
PAS or any of its Subsidiaries. As used in this Agreement, the term "Law"
means any applicable domestic or foreign, federal, state or local laws,
statutes, regulations, rules, codes, ordinances, orders and governmental
licenses, franchises, permits and governmental authorizations enacted,
adopted, issued or promulgated by any Government Entity (including, without
limitation, to the extent applicable, those pertaining to communications,
broadcasting, consumer protection, building, zoning, environmental and
occupational safety and health requirements and all requirements of the
Communications Act of 1934, as amended, or any successor statute, and the
rules and regulations of the FCC promulgated thereunder) or common law. As
used in this Agreement, the term "Permits" means all permits (including
conditional use permits), licenses, franchises, approvals, certificates,
concessions, privileges, immunities, consents or other authorizations issued
or authorized by any Government Entity.
 
  (b) Set forth on Schedule 5.6(b) is a true and complete list of all Permits
issued to or held by PAS or any of its Subsidiaries (as amended or modified),
except for Permits which are immaterial to the assets or business of PAS or
any of its Subsidiaries (collectively, the "PAS Permits"); provided, however,
that notwithstanding the foregoing materiality threshold, Schedule 5.6(b)
lists (i) all Permits issued by the FCC to PAS or any of its Subsidiaries,
(ii) all Permits, whether or not issued by the FCC, authorizing the
construction, launch or operation of the PAS Satellites or the PAS Ground
Stations (other than Permits granted or issued by local or municipal
Government Entities, such as building permits, local occupancy permits or
zoning regulations, which are not material to PAS and its Subsidiaries, taken
as a whole), and (iii) all Permits issued to PAS or any of its Subsidiaries by
Government Entities that regulate broadcasting or communications, authorizing
any of PAS or its Subsidiaries to provide broadcasting or communications
services. Schedule 5.6(b) also sets forth a true and complete list of all
pending applications for Permits that would be PAS Permits if issued or
granted and all
 
                                     A-14
<PAGE>
 
pending applications by PAS or its Subsidiaries for modification, extension or
renewal of PAS Permits. The PAS Permits are all of the Permits required to be
issued to or held by PAS or its Subsidiaries in order to allow PAS and its
Subsidiaries to own or lease their respective assets and to lawfully conduct
their respective businesses, including, without limitation, the construction,
launch and operation of, and transmitting to and from, each of the PAS
Satellites and the PAS Ground Stations (as such terms are defined in Section
5.19(a)) and the provision of broadcasting or communications services, except
where the failure to possess any such Permit is not likely to have a material
adverse effect on PAS and its Subsidiaries, taken as a whole. Notwithstanding
the generality of the preceding paragraph, except as set forth on Schedule
5.6(b), each of PAS and its Subsidiaries has fulfilled and complied in all
material respects with its obligations under each of the PAS Permits owned,
held or possessed by it, and no event has occurred or condition or state of
facts exists which constitutes or, after notice or lapse of time or both,
would constitute a breach or default under any PAS Permit and which permits
or, after notice or lapse of time or both, would permit revocation or
termination of any such PAS Permit, and neither PAS nor any of its
Subsidiaries has received or has knowledge of any written notice of
cancellation or default or of any dispute concerning any such PAS Permit, or
of any such event, condition or state of facts where the effect thereof would
be material to PAS and its Subsidiaries, taken as a whole. Each of the PAS
Permits is validly held by the entities listed on Schedule 5.6(b), is in full
force and effect in all material respects, is free and clear of all Liens
(other than Permitted Liens), is unimpaired by acts or omission of PAS or its
employees, partners or Affiliates, will expire on the date shown on Schedule
5.6(b), is valid for the balance of its current term, and is not subject to
any restriction or condition that limits in any material respect the full
operation of PAS' business as now operated. Except as set forth on Schedule
5.6(b) and for rulemaking proceedings affecting the satellite industry in
general, no complaints, proceedings or applications are pending, or to PAS'
best knowledge, threatened, at the FCC or any other Government Entity, that
would result in the revocation, forfeiture, adverse modification, non-renewal
or suspension of any of the PAS Permits, the denial of any pending application
by PAS or its Affiliates for a Permit or a modification, extension or renewal
thereof, the issuance against PAS of any cease and desist order, or the
imposition of any administrative actions by the FCC or any other Government
Entity with respect to the PAS Permits, or that would adversely affect the
ability of the corporation surviving the Merger to continue to operate the
business of PAS and its Subsidiaries as currently operated by such parties.
Except as set forth on Schedule 5.6(b), PAS has not received any complaint
that any of the PAS Satellites or the PAS Ground Stations is causing
objectionable interference to the transmissions or reception of any other
radio communications facility, and to PAS' best knowledge, no other radio
communications facility is causing objectionable interference to the
transmissions from or the receipt of signals by any PAS Satellite or PAS
Ground Station. Except as set forth on Schedule 5.6(b), none of the PAS
Permits that has been issued prior to the date hereof is the subject of any
pending renewal application; no renewal of any PAS Permit issued by the FCC
would constitute a major environmental action under the FCC Rules excluding
the impact of the FCC's new RF radiation rules adopted by the FCC in ET Docket
No. 93-62 on August 1, 1996; and PAS is not aware of any reason why the PAS
Permits will not be renewed in the ordinary course or why any of the PAS
Permits might be revoked. PAS knows of the existence of no fact that, under
present Law, would disqualify PAS from consummating the Merger within the time
contemplated herein. Except as set forth on Schedule 5.6(b), all information
contained in any pending application by PAS or any of its Subsidiaries for a
Permit or modification, extension, or renewal of a PAS Permit is true, correct
and complete in all material respects. Except as set forth on Schedule 5.6(b),
PAS has duly filed or caused to be filed with the FCC all required material
reports, statements, documents, registrations, filings or submissions with
respect to the operations of the business of PAS and its Subsidiaries, the PAS
Permits issued by the FCC, PAS' and its Subsidiaries' ownership of their
assets and the pending applications by PAS or any of its Subsidiaries for
Permits or for modification, extension or renewal of PAS Permits. All such
filings complied in all material respects with Laws when made and no
deficiencies have been asserted with respect to any such filings. Except for
rulemaking proceedings affecting the satellite industry in general, no
judgment, decree, order or notice of violation has been issued by the FCC (or
other Government Entity) which permits or contemplates revocation,
modification or termination of any of the PAS Permits or which would result in
any material impairment of any rights thereunder. As used in this Agreement,
the term "Affiliate" means with respect to any person or entity, any person or
entity which directly or indirectly controls, is controlled by or is under
common control with such person or entity; provided, however, that "Affiliate"
with respect to any person or entity shall also include any person or entity
of which the first person or entity directly or indirectly owns ten percent
(10%)
 
                                     A-15
<PAGE>
 
or more of the common equity and shall, in the case of each Hughes Party,
include HE, but exclude any person controlling HE and any person under common
control with HE but not itself controlled by HE.
 
  (c) Except as set forth on Schedule 5.6(c), neither PAS, its Subsidiaries or
Affiliates, nor any of their respective employees, are officials or officers
of any Government Entity or any political party, and neither PAS nor any of
its Subsidiaries or Affiliates has taken, is taking or will take, or has
allowed or will allow on its behalf to be taken, any action which would have
violated or would violate the United States Foreign Corrupt Practices Act of
1977, the U.S. Export Administration Act, as amended, or any Laws to which
such party or person is subject, relating in each case to payments for the
purpose of influencing an act or decision of a Government Entity or government
official; provided, however, that nothing in this sentence shall be deemed to
subject any party or person to any Law to which such party or person would not
otherwise be subject. Each of PAS and its Subsidiaries is in material
compliance with all domestic and foreign laws restricting or regulating the
export of technology to foreign countries.
 
  5.7 Litigation. Except as disclosed on Schedule 5.7 or in the PAS SEC
Documents, there is no suit, action or proceeding pending or, to PAS'
knowledge, threatened against or affecting PAS or any of its Subsidiaries, nor
is there any written judgment, decree, injunction, rule or order of any
Government Entity or arbitrator outstanding against PAS or any of its
Subsidiaries.
 
  5.8 Taxes. Each of PAS and its Subsidiaries has timely filed or has obtained
timely extensions for all tax returns required to be filed by such party
completely and accurately in all material respects and has timely paid (or PAS
has paid on behalf of any such Subsidiary), or has established an adequate
reserve for the payment of, all material taxes which are required to be paid
in respect of the taxable period reflected in such returns or for periods
since the most recent date on which a return was filed. All taxes shown to be
due on the tax returns that have been filed by PAS and each of its
Subsidiaries have been timely paid. Except as provided on Schedule 5.8,
neither PAS nor any of its Subsidiaries has waived any statute of limitations
in respect of taxes of PAS or any of its Subsidiaries. Except as provided on
Schedule 5.8, none of the tax returns filed by PAS or any of its Subsidiaries
has been examined by any taxing authority, and no audit, action, proceeding or
assessment is pending or threatened by any taxing authority against PAS or any
of its Subsidiaries where such audit, proceeding or assessment is likely to
have a material adverse effect on PAS and its Subsidiaries, taken as a whole.
All material taxes which PAS or any of its Subsidiaries is required by law to
withhold or to collect for payment have been duly withheld and collected, and
have been paid or accrued, reserved against and entered on the books of PAS.
There are no material liens for taxes (other than for current taxes not yet
due and payable) on the assets of PAS or any of its Subsidiaries. PAS has
previously delivered or made available to HCI true and complete copies of its
federal income tax returns for each of the fiscal years ended December 31,
1992 through December 31, 1995. Except as set forth on Schedule 5.8 or as
provided herein, neither PAS nor any of its Subsidiaries is a party to or
bound by any agreement providing for the allocation or sharing of taxes with
any entity which is not, either directly or indirectly, a Subsidiary of PAS.
Neither PAS nor any of its Subsidiaries has filed or is required to file a
consent pursuant to or agreed to the application of Section 341(f) of the
Code. PAS is not a "United States real property holding corporation" as
defined in Section 897(c)(2) of the Code during the applicable period
specified in Section 897(c)(1)(A)(ii) of the Code. For the purpose of this
Agreement, the term "tax" (and, with correlative meaning, the terms "taxes"
and "taxable") shall include all federal, state, local and foreign income,
profits, franchise, gross receipts, payroll, sales, employment, use, property,
withholding, excise and other taxes, duties or assessments of any nature
whatsoever, together with all interest, penalties and additions imposed with
respect to such amounts.
 
  5.9 Employees and Agents; Benefit Plans.
 
  (a) Schedule 5.9(a) contains a complete and accurate list of all employees
of PAS and its Subsidiaries, whether active or inactive, indicating thereon
the direct entity by whom such employee is employed and the employee's job
title. PAS also shall provide on Schedule 5.9(a) as to each such employee, the
position held, the length of service, employee loans, stock options, annual
salary, incentive bonuses, international and other allowances and PAS' cost of
dental, health (other than retiree health), life and long-term disability
insurance.

Except as set forth on Schedule 5.9(a), no employee of PAS or any of its
Subsidiaries is represented by any union, or covered by any collective
bargaining or similar agreement in connection with their employment at PAS,
nor is any such employee covered by a written agreement of employment in
connection with their employment at PAS, or to PAS' knowledge, any oral
employment agreement, which cannot be terminated at will by PAS or one of its
Subsidiaries or which provides for severance pay or other compensation,
including stock option rights and deferred compensation arrangements, upon
termination of employment or upon change of control of PAS or any of its
Subsidiaries. Except as listed and described on Schedule 5.9(a), neither PAS
nor any of its Subsidiaries is a party to any collective bargaining or other
similar labor agreement, including any such agreement which provides for or
may give rise to any liability or obligation for any severance or termination
pay or which will be the subject of renegotiation by virtue of the
consummation of the transactions contemplated by this Agreement, and to PAS'
knowledge, no labor organization has filed a petition to become the collective
bargaining representative with respect to PAS or any of its Subsidiaries.
 
  (b) Except as set forth on Schedule 5.9(b), PAS and each of its Subsidiaries
have complied in all material respects with all applicable employment and
labor laws, including but not limited to those relating to wages, hours,
collective bargaining, discrimination, plant closing notices, and the payment
of social security and similar taxes, and are not liable for any arrears of
wages or any material penalties for failure to comply with any of the
foregoing. There are no lawsuits, governmental proceedings, arbitration
proceedings or written claims pending or, to PAS' knowledge, threatened
between PAS or any of its Subsidiaries and any of their employees, or any
labor union or labor organization representing or purporting to represent any
of their employees. To PAS' knowledge, there are no union organizing or
election activities involving any non-union employees of PAS or any of its
Subsidiaries which have occurred since December 31, 1993 or threatened as of
the date hereof.
 
  (c) Schedule 5.9(c) sets forth a true and complete list of all of the
following, true, correct and complete copies of which have been delivered to

    (i) each "employee benefit plan," as defined in Section 3(3) of the
  Employee Retirement Income Security Act of 1974, as amended ("ERISA"), (the
  "PAS ERISA Plans") maintained, contributed to or required to be contributed
  to by PAS or any of its Subsidiaries, or under which PAS or any of its
  Subsidiaries could incur any liability, for the benefit of current, former
  and retired employees of PAS or any of its Subsidiaries ("PAS Employees")
  or any beneficiaries or dependents of any PAS Employees, except for foreign
  plans to which PAS is required to contribute pursuant to the law(s) of any
  foreign country;
 
    (ii) each other plan, program, policy, contract, agreement or arrangement
  providing for bonuses, pensions, deferred compensation, stock or stock
  related awards, severance pay, salary continuation or similar benefits,

not likely to have a material adverse effect on PAS and its Subsidiaries,
taken as a whole, each PAS ERISA Plan and PAS Benefit Arrangement has been
established and maintained in all material respects in accordance with its
terms and in material compliance with all Laws. PAS has listed on Schedule
5.9(d) all exceptions, without regard to whether such exceptions are likely to

  (e) Except as set forth on Schedule 5.9(e), neither PAS nor any of its
Subsidiaries have represented, promised or contracted (whether in oral or

provided with life insurance or employee health or welfare plan benefits upon
their retirement or termination of employment (except as may be required by
statute), except where such representation, promise or contract is not likely
to have a material adverse effect on PAS and its Subsidiaries, taken as a
whole. PAS has listed on Schedule
 
                                     A-17

any additional or subsequent events), shall constitute an event under any PAS
ERISA Plan, PAS Benefit Arrangement, loan or individual agreement or contract
that may result in any payment (whether of severance pay or otherwise),
restriction, or limitation upon the assets of any PAS ERISA Plan or PAS
Benefit Arrangement, acceleration of payment or vesting, increase in benefits

of its subsidiaries or the forgiveness of any loan or other commitment of any
PAS Employee.
 
  (h) Except as set forth on Schedule 5.9(h), there are no pending, or, to
PAS' knowledge, threatened actions or suits by or on behalf of any PAS ERISA

benefits), except to the extent that such pending or threatened actions or
suits are not likely to have a material adverse effect on PAS and its
Subsidiaries, taken as a whole.
 
  (i) Except as set forth on Schedule 5.9(i), with respect to each PAS ERISA
Plan that is funded wholly or partially through an insurance policy, there is

claims by PAS Employees against PAS or any of its Subsidiaries or any of its
PAS Employees, nor is PAS aware of any such pending lawsuits, governmental

pursuant to any applicable Law relating to employees, including human rights
legislation, labor standards legislation, occupational health and safety
legislation, worker's compensation legislation or any other employment-related
legislation.
 
  (l) Schedule 5.9(l) sets forth a complete and accurate list of any and all
loans of any nature whatsoever (other than routine travel advances) made by

<PAGE>
 
not likely to have a material adverse effect on PAS and its Subsidiaries,

  (q) It is the position of PAS that Section C of each Agreement listed in
number 12 of Schedule 5.9(c) means that, if a material change (as defined in
such agreement) should occur, the executive covered by such agreement shall be
entitled to no less than the aggregate employee welfare benefits that such
executive and such executive's dependents would have received under the
provisions of the benefit arrangements, policies or practices of PAS in effect
immediately prior to a material change, at no increased cost or expense to the
executive and such executive's dependents, in the aggregate.

  (b) The operations of PAS and its Subsidiaries are in substantial compliance
with all Environmental Laws. Except as set forth on Schedule 5.14(b), neither
PAS nor any of its Subsidiaries has received any written notice with respect
to any of its assets of any material violation of any Environmental Law.
 
  (c) Except as set forth on Schedule 5.14(c), there are no conditions
associated with PAS' assets, the operation of its business or PAS' owned or,
to PAS' knowledge, leased real property as currently operated that would under
applicable Environmental Law require or could reasonably be expected to
require PAS or any of its Subsidiaries to (i) undertake any action that would
materially impair the ability of PAS' business to use PAS' material owned and
leased real property as currently operated or PAS' material assets as
currently used, (ii) incur material expenditures or (iii) undertake remedial
obligations at any real property that is owned, operated or leased by PAS or

case which would cost individually in excess of $1.0 million.
 
  (d) Except as set forth on Schedule 5.14(d), as of the date hereof, PAS and
its Subsidiaries are not subject to any outstanding orders, agreements or
contracts with any Government Entity or other person respecting (i) violations
of Environmental Laws, (ii) Remedial Action or (iii) any Release or threatened
Release of a Hazardous Material, in either case which could be expected to
have a material adverse effect on PAS and its Subsidiaries, taken as a whole.
 
  5.15 Investment Banking Fees and Commissions. Except for Morgan Stanley &
Co. Incorporated and Salomon Brothers Inc (copies of whose engagement letters
with PAS have been furnished to HCI), no person or entity is entitled to
receive from PAS or any of its Subsidiaries or any of their directors,
officers or employees any investment banking, brokerage or finder's fee or
fees for financial consulting or other advisory services in connection with
this Agreement or the transactions contemplated hereby based upon arrangements
made by or on behalf of PAS, nor is any person or entity (including
stockholders of PAS) entitled to receive reimbursement from PAS or any of its
Subsidiaries for any such services or any legal fees and expenses.
 
  5.16 Material Contracts.
 
  (a) PAS has provided or made available to HCI or its independent auditors
and/or legal counsel (i) true and complete copies of all written Material
Contracts, or (ii) with respect to such Material Contracts that have not been
reduced to writing, a written description thereof, each of which is listed on
Schedule 5.16(a). Except as set forth on Schedule 5.16(a), neither PAS nor any
of its Subsidiaries has received any notice or has any knowledge that any
other party is, in default in any respect under any such Material Contract,
other than payment defaults under transponder lease agreements which are not
more than 90 days past due. Except as set forth on Schedule 5.16(a), each of
the Material Contracts of PAS and its Subsidiaries is in full force and effect
and constitutes a valid, legal and binding agreement of the parties thereto,
enforceable in accordance with its terms except for the Bankruptcy Exception.
As used in this Agreement, the term "Material Contract" means, as to any
person or entity, all written contracts, agreements, commitments,
arrangements, leases (including with respect to personal property), policies
and other instruments to which it or any of its Subsidiaries is a party or by
which it or any such Subsidiary is bound which, when assuming that all options
to renew or extend are exercised, (x) require payments to be made in excess of
$1,000,000 per year for goods and/or services, or (y) do not by their terms
expire and are not subject to termination within six months from the date of
the execution and delivery thereof and require payments to be made in excess
of $5,000,000 individually.
 
  (b) Except as set forth on Schedule 5.16(b), neither PAS nor its
Subsidiaries is a party, as of the date hereof, to any contract, agreement,
commitment, arrangement, lease (including with respect to personal property),
policy or other instrument that is not subject to termination by PAS upon less
than six months written notice to the other party thereto which materially
restricts or limits the right of PAS or any of its Subsidiaries or which
would, on or after the Closing Date, materially restrict or limit Newco's or
any of its Affiliates' right to conduct its business or compete, including
without limitation, any restriction on its ability to sell, lease or otherwise
provide services from available transponder capacity to any person or entity
for any purpose at any orbital location and in any frequency band, any
geographical, market segment, product line or other industry limitation, or
any
 
                                     A-22
<PAGE>
 
exclusive or sole supply or vendor arrangement or agreement. Nothing in this
Section 5.16(b) shall preclude or require disclosure on Schedule 5.16(b) of
most favored nations provisions, options for additional services or capacity,
rights of negotiation, or similar provisions agreed to in the ordinary course
of business (including, without limitation, of the kind set forth in the
agreements referenced on Schedule 5.16(a)).
 
  (c) As of June 30, 1996, the contracts, agreements, commitments,
arrangements, leases (including with respect to personal property) that
represent obligations of third parties to make payments to PAS in exchange for
the sale or lease of transponder capacity, have an aggregate stated amount of
unpaid payments owing to PAS of $3,026,000,000 over the remaining stated term
of such contracts, after allowance for doubtful accounts or other allowances
or deductions known as of such date which are ordinary and customary in the
conduct of PAS' business (the "PAS Backlog"). The PAS Backlog represents
amounts that, assuming the due performance by each party of its obligations
under each contract and the occurrence of no event that would permit
termination of a contract without liability to the terminating party, will be
due for, and will arise out of, bona fide sales and delivery of goods,
performance of services and other business transactions, unless the underlying
contract thereto is properly terminated in accordance with the terms thereof.
Except as set forth on Schedule 5.16(c), there are no refunds, discounts or
other adjustments payable by PAS with respect to any portion of the PAS
Backlog, and to the knowledge of PAS, there are no defenses, rights of setoff,
counterclaims, assignments, restrictions, encumbrances, or conditions
enforceable by any third parties on or affecting any portion of the PAS
Backlog. Except as set forth on Schedule 5.16(c), neither PAS nor any of its
Subsidiaries is, or has received any notice or has any knowledge that any
other party is, in default in any material respect under any contract
representing any portion of the PAS Backlog, other than (i) payment defaults
under transponder lease agreements which are not more than 90 days past due
and (ii) defaults or terminations under transponder lease agreements that are
promptly replaced by contracts providing for reasonably equivalent or superior
backlog payments.
 
  5.17 Personal Property. PAS and/or its Subsidiaries have good and valid
title to all personal property and assets (whether tangible or intangible)
reflected on the consolidated balance sheet of PAS and its Subsidiaries as of
December 31, 1995 (the "PAS Balance Sheet") or acquired after December 31,
1995, except for property and assets sold since December 31, 1995 in the
ordinary course of business and except for satellite systems under
development, with respect to which title will not be taken, other than as
provided in the applicable contract therefor; provided, that except as
disclosed on Schedule 5.17, there are no Liens with respect to any satellites
under development. Except as set forth on Schedule 5.17, none of such
properties or assets (whether real or personal) is subject to any mortgage,
life interest, lien, pledge, charge, security interest, fiduciary assignment,
hypothecation or title retention agreement relating to such properties or
assets (collectively, "Liens"), except:
 
    (i) Liens disclosed on the PAS Balance Sheet; or
 
    (ii) (a) Liens for taxes and other governmental charges and assessments
  arising in the ordinary course of business and in amounts comparable to the
  amounts of such Liens in prior years, which are not yet due and payable or,
  provided that an appropriate reserve has been established by the related
  person or entity, a Lien the amount or validity of which is being contested
  in good faith by appropriate proceedings, (b) Liens of landlords and Liens
  of carriers, warehousemen, mechanics and materialmen and other like Liens
  arising in the ordinary course of business for sums not yet due and payable
  and in amounts comparable to the amounts of such Liens in past years, and
  (c) Liens or imperfections on property which, individually or collectively,
  as to a party or any of its Subsidiaries, are not material in amount or do
  not materially detract from the value of or materially impair the existing
  use of the property affected by such Lien or imperfection (each, a
  "Permitted Lien").
 
  5.18 Real Property.
 
  (a) Schedule 5.18(a) sets forth a complete description of all real property
owned by PAS or any of its Subsidiaries (the "PAS Owned Real Property"),
together with a description of such ownership and the identity of the entity
that owns such property. PAS has good and valid title to the PAS Owned Real
Property and otherwise owns the PAS Owned Real Property free and clear of all
liens, security interests, claims and other
 
                                     A-23
<PAGE>
 
charges and encumbrances, except for (i) Permitted Liens and (ii)
encumbrances, if any, which do not materially impair the existing use of the
property.
 
  (b) Schedule 5.18(b) sets forth a list of all of the land, buildings and
other real property leased or sub-leased by PAS or any of its Subsidiaries
(the "PAS Leased Real Property"). PAS or one its Subsidiaries has a good and
valid leasehold interest in and right to peaceful quiet possession as against
each landlord with respect to each PAS Leased Real Property. True and complete
copies of all leases of the PAS Leased Real Property have been made available
for review to HCI. Such leases are in full force and effect according to their
terms, constitute the legal, valid and binding obligations of PAS and/or its
Subsidiaries party thereto and, to PAS' knowledge, such leases have not been
amended or modified except as disclosed in writing to HCI. Neither PAS nor any
of its Subsidiaries is in material default with respect to any of the leases
of the PAS Leased Real Property, nor has any event occurred which with the
passage of time, the giving of notice, or both, would constitute an event of
default or otherwise would place PAS or any of its Subsidiaries in material
default under any of such leases; neither PAS nor any of its Subsidiaries has
received any notice of any such default or event; and, to PAS' knowledge, no
landlord is in default under any of such leases, and no event has occurred
which with the passage of time, the giving of notice, or both, would
constitute an event of default or otherwise place any landlord in default
thereunder.
 
  (c) The PAS Owned Real Property and the PAS Leased Real Property, together
with facilities furnished under contract with others, comprise substantially
all of the real estate used in, or necessary to conduct, PAS' business, and
such use and occupancy is in conformance in all material respects with all
applicable laws, rules and regulations, including but not limited to,
applicable zoning, subdivision and other land use rules and regulations, the
violation of which is likely to have a material adverse effect on PAS and its
Subsidiaries, taken as a whole.
 
  (d) To PAS' knowledge, other than PAS or any of its Subsidiaries, there are
no parties in possession of any portion of the PAS Leased Real Property or the
PAS Owned Real Property, whether as lessees or sublessees thereof, or tenants
at sufferance, trespassers or otherwise, except as disclosed on Schedule
5.18(d). The location, construction, occupancy, operation or use of the PAS
Owned Real Property and, to the best knowledge of PAS, the PAS Leased Real
Property (including the buildings, improvements, fixtures and equipment
located thereon) do not contravene any laws, rules or regulations, or any
restrictive covenant or deed restriction (recorded or otherwise), or any PAS
Permit, affecting any of such property the contravention of which is likely to
have a material adverse effect on PAS and its Subsidiaries, taken as a whole.
There are no pending or, to the best knowledge of PAS, threatened condemnation
proceedings with respect to any PAS Leased Real Property, lease, or the PAS
Owned Real Property, or litigation or administrative actions relating thereto.
All buildings, improvements, fixtures and equipment used in connection with
PAS' business are located on the PAS Owned Real Property and the PAS Leased
Real Property and do not encroach on any adjoining property, and, to the best
knowledge of PAS, no buildings or improvements encroach upon the PAS Owned
Real Property or the PAS Leased Real Property which is likely to have a
material adverse effect on PAS and its Subsidiaries, taken as a whole.
 
  5.19 Certain Assets and Agreements.
 
  (a) Ground Stations. Each ground station, including, without limitation, the
related broadcasting facility assets (consisting of land, building, fixtures,
improvements and telemetry, tracking and control equipment) that is owned or
leased by PAS or any of its Subsidiaries in connection with PAS' business is
listed on Schedule 5.19(a) (the "PAS Ground Stations"). Except as otherwise
set forth on Schedule 5.19(a) with respect to each such ground station, the
improvements thereto and all components used in connection therewith,
including, without limitation, transmission/reception systems and programming
and data broadcasting systems, if any, (i) are in good operating condition and
repair and are suitable for their intended purposes and (ii) are supported by
a back-up, fuel-powered electricity generator capable of generating power
sufficient to meet the requirements of the operations conducted at the ground
station. The transmission/reception systems and programming and data
broadcasting systems at each such ground station have the redundancies that
are set forth on Schedule 5.19(a).
 
                                     A-24
<PAGE>
 
  (b) Satellites and Transponders. Set forth on Schedule 5.19(b) are the
following: (i) a complete and accurate list, by orbital location, of each
satellite and transponder thereon owned by PAS or any of its Subsidiaries in
connection with PAS' or any of its Subsidiaries' business (each a "PAS
Satellite"), (ii) a true and correct copy of a satellite loading chart listing
each transponder on each PAS Satellite, along with the type of transponder (C-
band, Ku-band or other) and the customer or group of related customers that
have leased or purchased capacity on such transponder and the amount of such
capacity, and (iii) the most recent "Health Status Report," summarizing all
spacecraft related incidents and anomalies known to PAS as well as the current
status, to the best knowledge of PAS, of the subsystems on the PAS Satellites
(power, telemetry and command, reaction control, communications and antenna).
For each PAS Satellite, true, correct and complete copies of the foregoing
will be delivered or made available to HCI (all such data, records, tapes,
information, lists and reports are collectively referred to herein as the "PAS
Data") prior to the Closing Date. Such PAS Data represent, to the best
knowledge of PAS, all relevant and material information relating to the
operating condition and repair of the PAS Satellites, and the fuel life
expectancies of the PAS Satellites. The information contained in the PAS Data
is, to the best knowledge of PAS, accurate and complete records (except as to
only those informational gaps disclosed to HCI) of the subject matters covered
therein; however, PAS makes no representation or warranty as to the accuracy
of any conclusion expressed as to fuel life expectancies of the PAS
Satellites. Such PAS Satellites are to the best of PAS' knowledge, subject to
the Health Status Reports, in good condition. Except as specifically provided
herein, PAS makes no representations or warranties, express or implied, with
respect to the PAS Satellites.
 
  (c) Tracking, Telemetry and Control Equipment. Except as otherwise set forth
on Schedule 5.19(c), to the best of PAS' knowledge, the tracking, telemetry
and control equipment (on the ground) used by third party contractors to
provide tracking, telemetry and control services related to each PAS Satellite
is (i) in good operating condition and repair, ordinary wear and tear
excepted, and (ii) not in need of maintenance or repairs except for ordinary,
routine maintenance and repairs.
 
  (d) ITU Frequency Registration. Schedule 5.19(d) contains a summary, by
orbital location, of the status of frequency registration at the International
Telecommunications Union, of each PAS Satellite, including the identity of the
sponsoring administration and the frequency bands covered.
 
  (e) Satellite Coordination. Except as set forth on Schedule 5.19(e), to the
best knowledge of PAS, no person or entity has asserted that it has rights to
operate a spacecraft in a manner that would result in interference with
respect to any PAS Satellite or any Satellite for which PAS has applied for a
Permit. Except as set forth on Schedule 5.19(e), PAS is not aware of any
asserted dispute with respect to PAS' continued ability to utilize any PAS
Satellite substantially in the manner that such PAS Satellite has been used in
connection with the business of PAS and its Subsidiaries to date. Schedule
5.19(e) also contains a list of all satellite coordination agreements to which
PAS or its Subsidiaries or Affiliates is a party, a summary of all operational
or technical limitations set forth therein, and a summary of all coordination
discussions with other persons or entities, domestic or foreign, with regard
to the PAS Satellites or any Satellite for which PAS has applied for a Permit
in which PAS or its Subsidiaries or Affiliates has been engaged in the past
three years.
 
  5.20 IGO Determinations. Schedule 5.20 contains a list of all consultations
and similar arrangements that have been effectuated with INTELSAT, EUTELSAT
and other similar intergovernmental entities, including without limitation all
Article XIV(c) and XIV(d) consultations under the INTELSAT Agreements
(collectively the "IGO Determinations") with respect to the PAS Satellites
that are needed to operate the business of PAS or any of its Subsidiaries as
they are now being conducted. Except as set forth on Schedule 5.20, PAS is not
aware of any difficulties in obtaining any other IGO Determinations with
respect to the PAS Satellites or any Satellite for which PAS has applied for a
Permit.

  Each Hughes Party and Newco represent and warrant to PAS as follows:
 
  6.1 Organization, Standing and Power. Each of the Hughes Parties is a
corporation duly organized, validly existing and in good standing under the
laws of its respective jurisdiction of incorporation, has all requisite
corporate power and authority necessary to own, lease and operate its
properties and to carry on its business as now being conducted, and is duly
qualified, and in good standing to own, lease and operate its properties and
to conduct its business relating to the Galaxy Business in each jurisdiction,
domestic and foreign, in which the operation of the Galaxy Business, or the
operation, ownership or leasing of the assets necessary to operate the Galaxy
Business, makes such qualification necessary, other than in such jurisdictions
where the failure to so qualify or be in good standing is not likely to have a
material adverse effect on the Galaxy Business. Each of the Hughes Parties
have heretofore made available to PAS true, complete and correct copies of its
Certificate of Incorporation and Bylaws as currently in effect together with
all amendments thereto. No resolution has been adopted to amend any of such
Certificates of Incorporation or Bylaws except as expressly called for by this
Agreement. None of the Hughes Parties (i) has been dissolved, adopted
resolutions to dissolve or acted in any way to accomplish, request or approve
such dissolution, (ii) is a party to any merger or (iii) has been declared
bankrupt, and, to such entity's knowledge, no action or request is pending to
declare it bankrupt. The Hughes Parties have made available to PAS minute
books for each of the Hughes Parties which contain complete and accurate
records in all material respects of all meetings, or consents in lieu thereof,
of the stockholders and the Board of Directors (including committees thereof)
of each such entity since its date of formation.
 
  6.2 Capital Structure. As of the date hereof, all of the issued and
outstanding shares of capital stock of the Contributed Entities and Newco are
validly issued, fully paid and nonassessable, are not subject to preemptive or
other similar rights, and are owned by HCI free and clear of all liens,
charges, encumbrances, claims and options of any nature. Except as set forth
on Schedule 6.2, none of the Contributed Entities (i) beneficially owns any
capital shares or has any other record or beneficial equity or other ownership
or interest in any corporation, partnership, joint venture, association or
other entity or business enterprise or (ii) has any commitment to contribute
to the capital of, make loans to, or share the losses of any person or entity
(other than any of the Contributed Entities). Except as set forth in this
Section 6.2, there are outstanding: (i) no shares of capital stock, or bonds,
debentures, notes or other instruments or evidence of indebtedness having the
right to vote (or convertible into, or exchangeable for, securities having the
right to vote), or other voting securities of any Contributed Entity or Newco
authorized, issued or outstanding; (ii) no securities of any Contributed
Entity or Newco are convertible into, or exchangeable or exercisable for,
shares of capital stock, or other voting securities of the Contributed
Entities or Newco; and (iii) no options, warrants, calls, rights (including
preemptive rights), commitments or agreements to which any Contributed Entity
or Newco is a party or by which it is bound, in any case obligating any
Contributed Entity or Newco to issue, deliver, sell, purchase, redeem or
acquire, or cause to be issued, delivered, sold, purchased, redeemed or
acquired, additional shares of capital stock or other voting securities of any
Contributed Entity or Newco, or obligating any Contributed Entity or Newco to
grant, extend or enter into any such option, warrant, call, right, convertible
security, commitment or agreement. None of the Contributed Entities nor Newco
has granted any options, warrants or rights to purchase any capital stock of
any Contributed Entity. Except as set forth on Schedule 6.2, there are not as
of the date hereof, and there will not be at the Effective Time, any
stockholder agreements, voting trusts or other agreements or understandings to
which any Contributed Entity or Newco is a party or by which it is bound
relating to the voting of any shares of the capital stock of any Contributed
Entity or Newco. There are no restrictions on HCI to vote the stock of any of
the Contributed Entities. Except as provided for herein, no person has any
rights to cause any Contributed Entity or Newco to register with the SEC any
securities of any Contributed Entity or Newco.
 
  6.3 Authority; No Violations; Consents and Approvals.
 
  (a) Each of the Hughes Parties has all requisite corporate power and
authority to execute and deliver this Agreement and the Related Agreements to
which it is a party and to perform its obligations hereunder and
 
                                     A-26
<PAGE>
 
thereunder and to effect the transactions contemplated hereby and thereby. The
execution, delivery and performance of this Agreement and the Related
Agreements to which a Hughes Party is a party and the consummation of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of each such entity. Each of this
Agreement and the Related Agreements to which a Hughes Party is a party has
been duly executed and delivered by such Hughes Party and assuming that each
of this Agreement and the Related Agreements to which a Hughes Party is a
party constitutes the valid and binding agreement of the other parties
thereto, and subject to obtaining all necessary approvals by Government
Entities, constitutes a valid and binding obligation of such Hughes Party
enforceable in accordance with its terms except that the enforcement hereby
may be limited by the Bankruptcy Exception.
 
  (b) The execution, delivery and performance by the Hughes Parties of each of
this Agreement and the Related Agreements to which a Hughes Party is a party
does not, and the consummation by the Hughes Parties of the transactions
contemplated hereby and thereby will not, (x) conflict with or result in any
violation of, or default (with or without notice or lapse of time, or both)
which is likely to have a material adverse effect on the Galaxy Business, or
give rise to a right of termination, cancellation or acceleration of any
obligation or the loss of a material benefit, or the creation of a material
lien, pledge, security interest or other encumbrance on assets or property, or
right of first refusal with respect to any material asset or property (any
such conflict, violation, default, right of termination, cancellation or
acceleration, loss, creation or right of first refusal, a "Galaxy Violation"),
under or pursuant to any provision of the respective Certificate of
Incorporation or Bylaws of such entity or equivalent constituent document of
any of its Subsidiaries or, (y) except as to which requisite waivers or
consents have been obtained and, except as set forth on Schedule 6.3(b) hereto
and assuming the consents, approvals, authorizations or permits and filings or
notifications referred to in paragraph (c) of this Section 6.3 are duly and
timely obtained or made, result in any Galaxy Violation of any Material
Contract, Galaxy ERISA Plan (as defined in Section 6.9(c)(i)), Galaxy Benefit
Arrangement (as defined in Section 6.9(c)(ii)), Galaxy Permit (as defined in
Section 6.6(b)), or Law applicable to such entity or the Galaxy Business;
provided, however, that nothing in this Section 6.3 will be deemed to
constitute a representation or warranty by any Hughes Party as to any
antitrust law or requirement.
 
  (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, notice to, or permit from any Government Entity is
required by or with respect to any Hughes Party in connection with the
execution and delivery by a Hughes Party of any of this Agreement or the
Related Agreements to which such Hughes Party is a party or the consummation
by any Hughes Party of the transactions contemplated hereby and thereby, which
if not obtained or made is likely to have a material adverse effect on such
Hughes Party's ability to consummate the transactions contemplated hereby and
thereby, except for: (A) the filing of a premerger notification and report
form by the applicable Hughes Party under the HSR Act and the expiration or
termination of the applicable waiting period thereunder; (B) the filing with
the SEC of (x) the Registration Statement (as defined in Section 7.5), and (y)

law; (F) the filing with the FCC of (x) the applications and waiver requests

pending FCC applications filed by the Hughes Parties, reflecting (subject to
FCC consent and consummation) the Asset Contribution, the Univisa Contribution
and the Merger, and (z) associated filings with the FCC that do not require
the FCC's consent or approval; and (G) such other consents, approvals, orders,
authorizations, registrations, declarations, filings, notices and Permits set
forth on Schedule 6.3(c).
 
  6.4 Galaxy Financial Statements. Attached as Schedule 6.4 are audited
consolidated balance sheets relating to the Galaxy Business as of December 31,
1994 and December 31, 1995 and an unaudited consolidated balance sheet as of
June 30, 1996 (the "Galaxy Balance Sheet") and the related audited
consolidated statements of operations for the two fiscal years ended December
31, 1995 and the unaudited consolidated statements of
 
                                     A-27
<PAGE>
 
operations for the six month period ended June 30, 1996 (such financial
statements being hereinafter referred to collectively as the "Galaxy Financial
Statements"). The Galaxy Financial Statements have been prepared from, and are
in accordance with, the books and records of the Galaxy Business, were
prepared in accordance with GAAP applied on a consistent basis during the
periods involved (except as may be indicated therein and, with respect to the
unaudited financial statements, subject to normal year end adjustments which
Galaxy's management believes would not be material in amount or effect) and
present fairly, in all material respects, in accordance with applicable
requirements of GAAP, the consolidated financial position of the Galaxy
Business as of their respective dates and the consolidated results of
operations of the Galaxy Business for the periods presented therein. The books
and all other financial records of the Galaxy Business are complete and
correct in all material respects. As of June 30, 1996, the Contributed
Entities have made capital expenditures for "satellites under construction" of
at least $175 million, all of which represents capital expenditures incurred
in the ordinary course of business and consistent with prudent business
practices and all rights to which are being transferred to Newco hereby.
 
  6.5 Information Supplied. The Registration Statement (as defined in Section
7.5), or any amendment thereof or supplement thereto, will not, on the date it
is first filed with the SEC and on the date it becomes effective contain any
untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading; provided, however, that no representation is made by any of the
Hughes Parties with respect to statements made therein based on information
supplied by PAS for inclusion in each Registration Statement. The information
supplied by any of the Hughes Parties for inclusion in the Proxy
Statement/Prospectus will not, on the date it is first mailed to the holders
of the shares of common stock of PAS or at the time of PAS' stockholder's
meeting contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made,
not misleading. Subject to the proviso set forth in the second preceding
sentence, the Proxy Statement/Prospectus, will comply as to form, in all
material respects, with the provisions of the Exchange Act and the rules and
regulations thereunder.
 
  6.6 Compliance with Laws.
 
  (a) Except as set forth on Schedule 6.6(a), the Galaxy Business is not being
conducted in violation of any Law the violation of which is likely to have a
material adverse effect on the Galaxy Business. Except as disclosed on
Schedule 6.6(a), no material investigation or review by any Government Entity
with respect to any of the Contributed Entities or the Galaxy Business is
pending or, to the best knowledge of any of the Hughes Parties, threatened and
none of the Hughes Parties has received any written citation or notification
alleging any violation of any Law or Permit the continuing violation of which
is likely to have a material adverse effect on the Galaxy Business.
 
  (b) Set forth on Schedule 6.6(b) is a true and complete list of all Permits
issued to or held by any of the Hughes Parties with respect to the Galaxy
Business (as amended or modified), except for Permits which are immaterial to
the Galaxy Business (collectively, the "Galaxy Permits"); provided, however,
that notwithstanding the foregoing materiality threshold, Schedule 6.6(b)
lists (i) all Permits issued by the FCC to any of the Hughes Parties relating
to the Galaxy Business, (ii) all Permits, whether or not issued by the FCC,
authorizing the construction, launch or operation of the Galaxy Satellites or
the Galaxy Ground Stations (other than Permits granted or issued by local or
municipal Government Entities, such as building permits, local occupancy
permits or zoning regulations, which are not material to the Galaxy Business),
and (iii) all Permits issued to the Hughes Parties (relating to the Galaxy
Business) by Government Entities that regulate broadcasting or communications,
authorizing any of the Contributed Entities to provide broadcasting or
communications services relating to the Galaxy Business. Schedule 6.6(b) also
sets forth a true and complete list of all pending applications for Permits
that would be Galaxy Permits if issued or granted and all pending applications
by any of the Hughes Parties for modification, extension or renewal of Galaxy
Permits. The Galaxy Permits are all of the Permits required to be issued to or
held by any of the Contributing Entities in order to allow the Contributed
Entities to own or lease their respective assets relating to the Galaxy
Business and to lawfully conduct the Galaxy Business, including,
 
                                     A-28
<PAGE>
 
without limitation, the construction, launch and operation of, and
transmitting to and from, each of the Galaxy Satellites and the Galaxy Ground
Stations (as such terms are defined in Section 6.18(a)), and the provision of
broadcasting or communications services, except where the failure to possess
any such Permit is not likely to have a material adverse effect on the Galaxy
Business. Notwithstanding the generality of the preceding paragraph, except as
set forth on Schedule 6.6(b), each of the Hughes Parties has fulfilled and
complied in all material respects with its obligations under each of the
Galaxy Permits owned, held or possessed by it, and no event has occurred or
condition or state of facts exists which constitutes or, after notice or lapse
of time or both, would constitute a breach or default under any Galaxy Permit
and which permits or, after notice or lapse of time or both, would permit
revocation or termination of any such Galaxy Permit, and no Hughes Party has
received or has knowledge of any written notice of cancellation or default or
of any dispute concerning any such Galaxy Permit, or of any such event,
condition or state of facts where the effect thereof would be material to the
Galaxy Business. Each of the Galaxy Permits is validly held by the entities
listed on Schedule 6.6(b), is in full force and effect in all material
respects, is free and clear of all Liens (other than Permitted Liens), is
unimpaired by acts or omission of any Hughes Party or their respective
employees, partners or Affiliates, will expire on the date shown on Schedule
6.6(b), is valid for the balance of its current term, and, except as set forth
on Schedule 6.6(b), is not subject to any restriction or condition that limits
in any material respect the full operation of the Galaxy Business as now
operated. Except as set forth on Schedule 6.6(b) and for rulemaking
proceedings affecting the satellite industry in general, no complaints,
proceedings or applications are pending, or to the Contributed Entities' best
knowledge, threatened, at the FCC or any other Government Entity, that would
result in the revocation, forfeiture, adverse modification, non-renewal or
suspension of any of the Galaxy Permits, the denial of any pending application
by any Hughes Party for a Permit in connection with the Galaxy Business or a
modification, extension or renewal thereof, the issuance against any Hughes
Party of any cease and desist order with respect to the Galaxy Business, or
the imposition of any administrative actions by the FCC or any other
Government Entity with respect to the Galaxy Permits, or that would adversely
affect the ability of Newco after the Asset Contribution to continue to
operate the Galaxy Business as currently operated by the Contributed Entities.
Except as set forth on Schedule 6.6(b), none of the Hughes Parties has
received any complaint that any of the Galaxy Satellites or the Galaxy Ground
Stations is causing objectionable interference to the transmissions or
reception of any other radio communications facility, and to the best
knowledge of such entity, no other radio communications facility is causing
objectionable interference to the transmissions from or the receipt of signals
by any Galaxy Satellite or Galaxy Ground Station. Except as set forth on
Schedule 6.6(b), none of the Galaxy Permits that has been issued prior to the
date hereof is the subject of any pending renewal application; no renewal of
any Galaxy Permit issued by the FCC would constitute a major environmental
action under the FCC Rules excluding the impact of the FCC's new RF radiation
rules adopted by the FCC in ET Docket No. 93-62 on August 1, 1996; and none of
the Hughes Parties is aware of any reason why the Galaxy Permits will not be
renewed in the ordinary course or why any of the Galaxy Permits might be
revoked. None of the Hughes Parties knows of the existence of any fact that,
under present Law, would disqualify Galaxy from consummating the Asset
Contribution within the time contemplated herein. Except as set forth on
Schedule 6.6(b), all information contained in any pending application by a
Hughes Party for a Permit in connection with the Galaxy Business or
modification, extension, or renewal of a Galaxy Permit is true, correct and
complete in all material respects. Except as set forth on Schedule 6.6(b),
each of the Hughes Parties have duly filed or caused to be filed with the FCC
all required material reports, statements, documents, registrations, filings
or submissions with respect to the operations of the Galaxy Business, the
Galaxy Permits issued by the FCC, the Hughes Parties' ownership of their
assets in connection with the Galaxy Business and the pending applications by
any of the Hughes Parties for Permits or for modification, extension or
renewal of Galaxy Permits. All such filings complied in all material respects
with Laws when made and no deficiencies have been asserted with respect to any
such filings. Except for rulemaking proceedings affecting the satellite
industry in general, no judgment, decree, order or notice of violation has
been issued by the FCC (or other Government Entity) which permits or
contemplates revocation, modification or termination of any of the Galaxy
Permits or which would result in any material impairment of any rights
thereunder.
 
  (c) Except as set forth on Schedule 6.6(c), none of the Hughes Parties, nor
any of their Subsidiaries or Affiliates, nor any of their respective
employees, are officials or officers of any Government Entity or any
 
                                     A-29
<PAGE>
 
political party, and none of the Contributed Entities, nor any of their
Subsidiaries or Affiliates has taken, is taking or will take, or has allowed
or will allow on its behalf to be taken, any action which would have violated
or would violate the United States Foreign Corrupt Practices Act of 1977, the
U.S. Export Administration Act, as amended, or any Laws to which such party or
person is subject, relating in each case to payments for the purpose of
influencing an act or decision of a Government Entity or government official;
provided, however, that nothing in this sentence shall be deemed to subject
any party or person to any Law to which such party or person would not
otherwise be subject. With respect to the Galaxy Business, each of the Hughes
Parties is in material compliance with all domestic and foreign laws
restricting or regulating the export of technology to foreign countries.
 
  6.7 Litigation. Except as disclosed on Schedule 6.7, there is no suit,
action or proceeding pending or, to the knowledge of any of the Hughes
Parties, threatened against any of the Contributed Entities or affecting the
Galaxy Business, nor is there any written judgment, decree, injunction, rule
or order of any Government Entity or arbitrator outstanding against any
Contributed Entity in respect of the Galaxy Business.
 
  6.8 Taxes. Each of the Contributed Entities has timely filed or has obtained
timely extensions for all tax returns required to be filed by such party
completely and accurately in all material respects and has timely paid (or
such entity's parent has paid), or has established an adequate reserve for the
payment of, all material taxes which are required to be paid in respect of the
taxable period reflected in such returns or for periods since the most recent
date on which a return was filed. All taxes shown to be due on the tax returns
that have been filed by the Contributed Entities have been timely paid. Except
as provided on Schedule 6.8, none of the Contributed Entities has waived any
statute of limitations in respect of taxes of such entity. Except as provided
on Schedule 6.8, none of the tax returns filed by the Contributed Entities has
been examined by any taxing authority, and no audit, action, proceeding or
assessment is pending or threatened by any taxing authority against the
Contributed Entities where such audit, proceeding or assessment is likely to
have a material adverse effect on the Galaxy Business. All material taxes
which any of the Contributed Entities is required by law to withhold or to
collect for payment with respect to the Galaxy Business have been duly
withheld and collected, and have been paid or accrued, reserved against and
entered on the books of such entity. There are no material liens for taxes
(other than for current taxes not yet due and payable) on the assets of any of
the Contributed Entities relating to the Galaxy Business. The Contributed
Entities have previously delivered or made available to PAS true and complete
copies of their federal income tax returns for each of the fiscal years ended
December 31, 1992 through December 31, 1995. Except as set forth on Schedule
6.8 or as provided herein, none of the Contributed Entities is a party to or
bound by any agreement providing for the allocation or sharing of taxes with
any entity which is not, either directly or indirectly, a Contributed Entity.
None of the Contributed Entities has filed or is required to file a consent
pursuant to or agreed to the application of Section 341(f) of the Code. None
of the Contributed Entities is a "United States real property holding
corporation" as defined in Section 897(c)(2) of the Code during the applicable
period specified in Section 897(c)(1)(A)(ii) of the Code.
 
  6.9 Employees and Agents; Benefit Plans.
 
  (a) Schedule 6.9(a) contains a complete and accurate list of all employees
of the Contributed Entities who work primarily in the Galaxy Business (the
"Galaxy Employees"), whether active or inactive, indicating thereon the direct
entity by whom such employee is employed and the employee's job title. Upon
the completion of the Asset Contribution, each of the Galaxy Employees, to the
extent still employed in connection with the Galaxy Business, will become an
employee of Newco or one of its wholly-owned Subsidiaries. HCI also shall
provide on Schedule 6.9(a) or on a separate schedule that HE shall deliver to
PAS within 20 days after the execution of this Agreement, a list that
specifically identifies all employees that were listed on the list provided
for in the first sentence of this subsection and who shall be employed by the
Newco as of the Effective Time showing for each, the position held, the length
of service, employee loans, stock options, annual salary, incentive bonuses,
international and other allowances and the Contributed Entities' cost of
dental, health (other than retiree health), life and long-term disability
insurance. Except as set forth on Schedule 6.9(a), no Galaxy Employee is
represented by any union, or covered by any collective bargaining or similar
agreement in connection with their employment at any Contributed Entity, nor
is any such employee covered by a written agreement of employment
 
                                     A-30
<PAGE>
 
in connection with their employment at any Contributed Entity, or to the
knowledge of the Contributed Entities, any oral employment agreement, which
cannot be terminated at will by any of the Contributed Entities or which
provides for severance pay or other compensation, including stock option
rights and deferred compensation arrangements, upon termination of employment
or upon change of control of the Contributed Entities. Except as listed and
described on Schedule 6.9(a), none of the Contributed Entities is a party to
any collective bargaining or other similar labor agreement, including any such
agreement which provides for or may give rise to any liability or obligation
for any severance or termination pay or which will be the subject of
renegotiation by virtue of the consummation of the transactions contemplated
by this Agreement, and to each Hughes Party's knowledge, no labor organization
has filed a petition to become the collective bargaining representative with
respect to any of the Contributed Entities.
 
  (b) Except as set forth on Schedule 6.9(b), the Contributed Entities have
complied in all material respects with all applicable employment and labor
laws with respect to the Galaxy Employees, including but not limited to those
relating to wages, hours, collective bargaining, discrimination, plant closing
notices, and the payment of social security and similar taxes, and are not
liable for any arrears of wages or any material penalties for failure to
comply with any of the foregoing. There are no lawsuits, governmental
proceedings, arbitration proceedings or written claims pending or, to the
Contributed Entities' knowledge, threatened between the Contributed Entities
and any of the Galaxy Employees, or any labor union or labor organization
representing or purporting to represent any of the Galaxy Employees. To the
Contributed Entities' knowledge, there are no union organizing or election
activities involving any non-union Galaxy Employees which have occurred since
December 31, 1993 or threatened as of the date hereof.
 
  (c) Schedule 6.9(c) sets forth a true and complete list of all of the
following, true, correct and complete copies of which have been delivered to

    (i) each "employee benefit plan," as defined in Section 3(3) of ERISA,
  (the "Galaxy ERISA Plans") maintained, contributed to or required to be
  contributed to by the Galaxy Business, or under which the Galaxy Business
  could incur any liability, for the benefit of current, former and retired
  employees of the Contributed Entities ("Galaxy Benefit Employees") or any
  beneficiaries or dependents of any Galaxy Benefit Employees, except for
  foreign plans to which the Contributed Entities are required to contribute
  pursuant to the law(s) of any foreign country;
 
    (ii) each other plan, program, policy, contract, agreement or arrangement
  providing for bonuses, pensions, deferred compensation, stock or stock
  related awards, severance pay, salary continuation or similar benefits,
  hospitalization, medical, dental or disability benefits, life insurance or
  other employee benefits, or compensation to or for any Galaxy Benefit
  Employee or members of any Galaxy Benefit Employee's families (other than
  directors and officers' liability policies), whether or not insured or
  funded (a "Galaxy Benefit Arrangement").
 
  (d) Except as set forth on Schedule 6.9(d), and except where such failure is
not likely to have a material adverse effect on the Galaxy Business, each
Galaxy ERISA Plan and Galaxy Benefit Arrangement has been established and
maintained in all material respects in accordance with its terms and in
material compliance with all Laws. HCI has listed on Schedule 6.9(d) all
exceptions, without regard to whether such exceptions are likely to have a
material adverse effect on the Galaxy's Business, to this Section 6.9(d) of
which HCI or any of the Contributed Entities have actual knowledge.
 
  (e) Except as set forth on Schedule 6.9(e), none of the Contributed Entities
have represented, promised or contracted (whether in oral or written form) to
any current or former Galaxy Benefit Employee (either individually or to
Galaxy Benefit Employees as a group) that such current or former Galaxy
Benefit Employee(s) would be provided with life insurance or employee health
or welfare plan benefits upon their retirement or termination of employment
(except as may be required by statute), except where such representation,
promise or contract is not likely to have a material adverse effect on the
Galaxy Business. HCI has listed on Schedule 6.9(e) all exceptions, without
regard to whether such exceptions are likely to have a material adverse effect
on the Galaxy Business, to this Section 6.9(e) of which HCI or any of the
Contributed Entities have actual knowledge.

and all Galaxy Benefit Arrangements and employment severance agreements
pursuant to plans which the Galaxy Business has or may have any liability.
 
  (g) Except as set forth on Schedule 6.9(g), neither the execution or
delivery of this Agreement or the Related Agreements nor the consummation of
the transactions contemplated hereby or thereby (either alone or together with
any additional or subsequent events), shall constitute an event under any
Galaxy ERISA Plan, Galaxy Benefit Arrangement, loan or individual agreement or
contract that may result in any payment (whether of severance pay or
otherwise), restriction, or limitation upon the assets of any Galaxy ERISA
Plan or Galaxy Benefit Arrangement, acceleration of payment or vesting,
increase in benefits or compensation, or required funding with respect to any
Galaxy Benefit Employee or any of its subsidiaries or the forgiveness of any
loan or other commitment of any Galaxy Benefit Employee.
 
  (h) Except as set forth on Schedule 6.9(h), there are no pending, or, to the

Benefit Employee or beneficiary covered under any such Galaxy ERISA Plan or
Galaxy Benefit Arrangement, or otherwise involving any such plan or
arrangement (other than routine claims for benefits), except to the extent
that such pending or threatened actions or suits are not likely to have a
material adverse effect on the Galaxy Business.
 
  (i) Except as set forth on Schedule 6.9(i), with respect to each Galaxy
ERISA Plan that is funded wholly or partially through an insurance policy,
there is no liability of the Galaxy Business under any such insurance policy
or ancillary agreement with respect to such insurance policy in the nature of
a retroactive rate adjustment, loss sharing arrangement or other actual or
contingent liability arising wholly or partially out of events occurring prior
to the Effective Time which is likely to have a material adverse effect on the
Galaxy Business.
 
  (j) Except as set forth on Schedule 6.9(j), all employee contributions to
Galaxy ERISA Plans to the date hereof have been properly withheld by the
Galaxy Business, all contributions required to be made to each such plan by

deferrals and employer matching or other contributions) have been made on a
timely basis or will be made on a timely basis and all of such contributions
have been or will be fully paid into the funding arrangements for the
respective Galaxy ERISA Plan, except where such failure is not likely to have
a material adverse effect on the Galaxy Business.

adequate insurance with respect to its properties and business related to the
Galaxy Business against loss or damage of the kinds customarily insured
against by corporations of established reputation engaged in the same or
similar businesses and similarly situated, of such types and in such amounts
as are customarily carried under similar circumstances by such other

notice with respect to any of its assets of any material violation of any
Environmental Law with respect to the Galaxy Business.
 
  (b) Except as set forth on Schedule 6.13(b), there are no conditions
associated with assets of the Galaxy Business, the operation of the Galaxy
Business or owned or, to each Contributed Entity's Knowledge, leased real

under applicable Environmental Law require or could reasonably be expected to
require any of the Contributed Entities to (i) undertake any action that would
materially impair the ability of such entity to use the material owned and
leased real property that relate to the Galaxy Business as currently operated
or the material assets of the Galaxy Business as currently used, (ii) incur
material expenditures or (iii) undertake remedial obligations at any real
property that is owned, operated or leased by any of the Contributed Entities

in connection with the Galaxy Business which would cost individually in excess
of $1.0 million.
 
  (c) Except as set forth on Schedule 6.13(c), as of the date hereof, none of
the Contributed Entities is subject to any outstanding orders, agreements or
contracts with any Government Entity or other person respecting (i) violations

have a material adverse effect on the Galaxy Business.
 
  6.14 Investment Banking Fees and Commissions. Except for Greenhill & Co.,
LLC and Donaldson, Lufkin & Jenrette Securities Corporation (copies of whose
engagement letters with HE have been furnished to PAS), no person or entity is
entitled to receive from the Hughes Parties or any of their Subsidiaries or
any of their directors, officers or employees any investment banking,

hereby based upon arrangements made by or on behalf of the Hughes Parties, nor
is any person or entity entitled to receive reimbursement from the Hughes
Parties or any of their Subsidiaries for any such services or any legal fees
and expenses.
 
  6.15 Material Contracts.
 
  (a) HCI has provided or made available to PAS or its independent auditors
and/or legal counsel (i) true and complete copies of all written Material
Contracts relating to the Galaxy Business, or (ii) with respect to such
Material Contracts that have not been reduced to writing, a written
description thereof, each of which is listed on Schedule 6.15(a). Except as
set forth on Schedule 6.15(a), none of the Contributed Entities has received
any notice or has any knowledge that any other party is, in default in any
respect under any such Material Contract, other than payment defaults under
transponder lease agreements which are not more than 90 days past due. Each of
the Material Contracts relating to the Galaxy Business is in full force and
effect and constitutes a valid, legal and binding agreement of the parties
thereto, enforceable in accordance with its terms except for the Bankruptcy
Exception.
 
  (b) Except as set forth on Schedule 6.15(b), none of the Hughes Parties is a
party, as of the date hereof, to any contract, agreement, commitment,
arrangement, lease (including with respect to personal property), policy or
other instrument that is not subject to termination by such Hughes Party upon
less than six months written notice to the other party thereto which
materially restricts or limits the right of any Hughes Party or, which would,
on or after the Closing Date, materially restrict or limit Newco's or any of
its Affiliates' right to conduct its business or compete, including without
limitation, any restriction on its ability to sell, lease or otherwise provide
services from available transponder capacity to any person or entity for any
purpose at any orbital location and in any frequency band, any geographical,
market segment, product line or other industry limitation,
 
                                     A-35
<PAGE>
 
or any exclusive or sole supply or vendor arrangement or agreement. Nothing in
this Section 6.15(b) shall preclude or require disclosure on Schedule 6.15(b)
of most favored nations provisions, options for additional services or
capacity, rights of negotiation, or similar provisions agreed to in the
ordinary course of business (including, without limitation, of the kind set
forth in the agreements referenced on Schedule 6.15(a)).
 
  (c) As of June 30, 1996, the contracts, agreements, commitments,
arrangements, leases (including with respect to personal property) that
represent obligations of third parties to make payments to any Hughes Party in
exchange for the sale or lease of transponder capacity, have an aggregate
stated amount of unpaid payments owing to the Hughes Parties of $3,394,000,000
over the remaining stated term of such contracts, after allowance for doubtful
accounts or other allowances or deductions known as of such date which are
ordinary and customary in the conduct of the Galaxy Business (the "Galaxy
Backlog"). The Galaxy Backlog represents amounts that, assuming the due
performance by each party of its obligations under each contract and the
occurrence of no event that would permit termination of a contract without
liability to the terminating party, will be due for, and will arise out of,
bona fide sales and delivery of goods, performance of services and other
business transactions, unless the underlying contract thereto is properly
terminated in accordance with the terms thereof. Except as set forth on
Schedule 6.15(c), there are no refunds, discounts or other adjustments payable
by any Hughes Party with respect to any portion of the Galaxy Backlog, and to
the knowledge of Galaxy, there are no defenses, rights of setoff,
counterclaims, assignments, restrictions, encumbrances, or conditions
enforceable by any third parties on or affecting any portion of the Galaxy
Backlog. Except as set forth on Schedule 6.15(c), none of the Hughes Parties
is, or has received any notice or has any knowledge that any other party is,
in default in any material respect under any contract representing any portion
of the Galaxy Backlog, other than (i) payment defaults under transponder lease
agreements which are not more than 90 days past due (ii) defaults under
contracts representing the Galaxy Backlog that do not have a stated backlog in
excess of $500,000 in the aggregate for the stated contract term, and (iii)
defaults or terminations under transponder lease agreements that are promptly
replaced by contracts providing for reasonably equivalent or superior backlog
payments.
 
  6.16 Personal Property. The Contributed Entities have, and immediately after
the Closing Newco will have, good and valid title to all personal property and
assets (whether tangible or intangible) related to the Galaxy Business
reflected on the consolidated balance sheet of the Galaxy Business as of June
30, 1996 or acquired after June 30, 1996, except for property and assets sold
since June 30, 1996 in the ordinary course of business and except for
satellite systems under development by the Galaxy Business, with respect to
which title will not be taken, other than as provided in the applicable
contract therefor provided that except as disclosed on Schedule 6.16 there are
no material Liens with respect to any satellites under development. Except as
set forth on Schedule 6.16, none of such properties or assets (whether real or
personal) is subject to any Liens, except:
 
    (i) Liens disclosed on the Galaxy Balance Sheet; or
 
    (ii) any Permitted Liens.
 
  6.17 Real Property.
 
  (a) Schedule 6.17(a) sets forth a complete description of all real property
owned by the Contributed Entities that relate to the Galaxy Business (the
"Galaxy Owned Real Property"), together with a description of such ownership
and the identity of the entity that owns such property. The Contributed
Entities have good and valid title to the Galaxy Owned Real Property and
otherwise own the Galaxy Owned Real Property free and clear of all liens,
security interests, claims and other charges and encumbrances, except for (i)
Permitted Liens and (ii) encumbrances, if any, which do not materially impair
the existing use of the property.
 
  (b) Schedule 6.17(b) sets forth a list of all of the land, buildings and
other real property leased or sub-leased by the Contributed Entities in
connection with the Galaxy Business (the "Galaxy Leased Real Property"). The
Contributed Entities have a good and valid leasehold interest in and right to
peaceful quiet possession as against each landlord with respect to each Galaxy
Leased Real Property. True and complete copies of all leases of the Galaxy
Leased Real Property have been made available for review to PAS. Such leases
are in full force and effect according to their terms, constitute the legal,
valid and binding obligations of the Contributed Entity that is a party
thereto and, to the Contributed Entities' knowledge, such leases have not been
amended or modified
 
                                     A-36
<PAGE>
 
except as disclosed in writing to PAS. None of the Contributed Entities is in
material default with respect to any of the leases of the Galaxy Leased Real
Property, nor has any event occurred which with the passage of time, the
giving of notice, or both, would constitute an event of default or otherwise
would place such Contributed Entity in material default under any of such
leases; none of the Contributed Entities have received any notice of any such
default or event; and, to the Contributed Entities' knowledge, no landlord is
in default under any of such leases, and no event has occurred which with the
passage of time, the giving of notice, or both, would constitute an event of
default or otherwise place any landlord in default thereunder.
 
  (c) The Galaxy Owned Real Property and the Galaxy Leased Real Property,
together with facilities furnished under contract with others, comprise
substantially all of the real estate used in, or necessary to conduct, the
Galaxy Business, and such use and occupancy is in conformance in all material
respects with all applicable laws, rules and regulations, including but not
limited to, applicable zoning, subdivision and other land use rules and
regulations, the violation of which is likely to have a material adverse
effect on the Galaxy Business.
 
  (d) To the Contributed Entities' knowledge, other than the Contributed
Entities, there are no parties in possession of any portion of the Galaxy
Leased Real Property or the Galaxy Owned Real Property, whether as lessees or
sublessees thereof, or tenants at sufferance, trespassers or otherwise, except
as disclosed on Schedule 6.17(d). The location, construction, occupancy,
operation or use of the Galaxy Owned Real Property and, to the best knowledge
of the Contributed Entities, the Galaxy Leased Real Property (including the
buildings, improvements, fixtures and equipment located thereon) do not
contravene any laws, rules or regulations, or any restrictive covenant or deed
restriction (recorded or otherwise), or any Galaxy Permit, affecting any of
such property the contravention of which is likely to have a material adverse
effect on the Galaxy Business. There are no pending or, to the best knowledge
of the Contributed Entities, threatened condemnation proceedings with respect
to any Galaxy Leased Real Property, lease, or the Galaxy Owned Real Property,
or litigation or administrative actions relating thereto. All buildings,
improvements, fixtures and equipment used in connection with the Galaxy
Business are located on the Galaxy Owned Real Property and the Galaxy Leased
Real Property and do not encroach on any adjoining property, and, to the best
knowledge of the Hughes Parties, no buildings or improvements encroach upon
the Galaxy Owned Real Property or the Galaxy Leased Real Property which is
likely to have a material adverse effect on the Galaxy Business.

antenna), and (iv) a list of all satellites under construction, all satellites
that have
 
                                     A-37

been constructed but not launched, including describing the status of launch
insurance, the coverage thereunder and the premium to be paid in connection
therewith. For each Galaxy Satellite, true, correct and complete copies of the
foregoing will be delivered or made available to PAS (all such data, records,
tapes, information, lists and reports are collectively referred to herein as
the "Galaxy Data") prior to the Closing Date. Such Galaxy Data represent, to
the best knowledge of the Contributed Entities, all relevant and material
information relating to the operating condition and repair of the Galaxy
Satellites, and the fuel life expectancies of the Galaxy Satellites. The
information contained in the Galaxy Data is, to the best knowledge of the
Contributed Entities, accurate and complete records (except as to only those
informational gaps disclosed to PAS) of the subject matters covered therein;
however, such parties make no representation or warranty as to the accuracy of
any conclusion expressed as to fuel life expectancies of the Galaxy
Satellites. Such Galaxy Satellites are to the best knowledge of each of the
Hughes Parties, subject to the Health Status Reports, in good condition.
Except as specifically provided herein, no representation or warranty, express
or implied, is made with respect to the Galaxy Satellites.
 
  (c) Tracking, Telemetry and Control Equipment. Except as otherwise set forth
on Schedule 6.18(c), to the best knowledge of the Contributed Entities, the

best knowledge of the Contributed Entities, no person or entity has asserted
that it has rights to operate a spacecraft in a manner that would result in
interference with respect to any Galaxy Satellite or any Satellite to be used
in connection with the Galaxy Business for which a Contributed Entity has
applied for a Permit. Except as set forth on Schedule 6.18(e), none of the
Contributed Entities is aware of any asserted dispute with respect to such
entity's continued ability to utilize any Galaxy Satellite substantially in
the manner that such Galaxy Satellite has been used in connection with the
Galaxy Business to date. Schedule 6.18(e) also contains a list of all
satellite coordination agreements to which any of the Contributed Entities or
their Affiliates is a party, a summary of all operational or technical
limitations set forth therein and a summary of all coordination discussions
with other persons or entities, domestic or foreign, with regard to the Galaxy
Satellites or any Satellite to be used in connection with the Galaxy Business
for which a Contributed Entity has applied for a Permit in which any of the
Contributed Entities or their Affiliates has been engaged in the past three
years.
 
  6.19 IGO Determinations. Schedule 6.19 contains a list of all IGO
Determinations with respect to the Galaxy Satellites that are needed to
operate Galaxy Business as it is now being conducted. Except as set forth on
Schedule 6.19, none of the Contributed Entities is aware of any difficulties
in obtaining any other IGO Determinations with respect to the Galaxy
Satellites or any Satellite to be used in connection with the Galaxy Business
for which a Contributed Entity has applied for a Permit.

  (g) and (k) below, the pursuit of and consummation by PAS of strategic
  partnerships, joint ventures, acquisitions and similar activities and
  investments shall be considered to be in the "ordinary course" for PAS if,
  in each case, such activities and investments are ancillary to the sale or
  lease of, or the provision of service or capacity via, transponders by PAS.

  employees, representatives, agents or Affiliates (including, without
  limitation, any investment banker, attorney or accountant retained by PAS
  or any of its Subsidiaries) to, directly or indirectly, enter into,
  solicit, initiate or continue any discussions or negotiations with, or
  encourage or respond to any inquiries or proposals by, or participate in
  any negotiations with, or provide any information to, or otherwise
  cooperate in any other way with, any corporation, partnership, person or
  other entity or group (each, a "Person") (other than HCI, Galaxy or any of
  their Affiliates or representatives), concerning any offer or proposal
  which constitutes or is reasonably likely to lead to any Acquisition
  Proposal; provided that the Board of Directors of PAS may, in the event of
  an unsolicited Acquisition Proposal, engage in negotiations or discussions
  with, or provide information or data to, any Person relating to an
  Acquisition Proposal if (x) the Acquisition Proposal is a bona fide fully-
  financed written offer submitted to PAS' Board of Directors and such Board
  of Directors, after consulting with a nationally recognized investment
  bank, determines that such Acquisition Proposal is economically superior to
  the transactions contemplated by this Agreement and the Related Agreements
  (a "Superior Acquisition Proposal"), and (y) PAS' Board of Directors
  determines, after having received the written opinion of outside legal
  counsel to PAS, that the failure to engage in such negotiations or
  discussions or provide such information would result in a breach of the
  fiduciary duties of the Board of Directors of PAS under applicable law.
  Then, in such event, the Board of Directors may withdraw or modify its
  approval or recommendation of the Merger or this Agreement, approve or
  recommend the Superior Acquisition Proposal or terminate this Agreement
  pursuant to Section 9.1(g) hereof. HCI shall have the right to match any
  such Superior Acquisition Proposal, and have such matching proposal
  immediately accepted by PAS, for five (5) business days after HCI is
  informed of the necessary
 
                                     A-39
<PAGE>
 
  determinations in clauses (x) and (y) of the preceding sentence with
  respect to such Superior Acquisition Proposal. Any information furnished to
  any Person in connection with an Acquisition Proposal shall be provided
  pursuant to a confidentiality agreement in customary form on terms not more
  favorable to such Person than the terms contained in the Confidentiality
  Agreement (as defined in Section 7.6). Subject to all of the foregoing
  requirements, PAS will immediately notify HCI orally and in writing if any
  discussions or negotiations are sought to be initiated, any inquiry or
  proposal is made, or any information is requested by any Person with
  respect to any Acquisition Proposal or which could lead to an Acquisition
  Proposal and immediately notify HCI of all material terms of any proposal
  which it may receive in respect of any such Acquisition Proposal, including
  the identity of the Person making the Acquisition Proposal or the request
  for information, if known, and thereafter shall inform HCI on a timely,
  ongoing basis of the status and content of any discussions or negotiations
  with such a third party, including immediately reporting any material
  changes to the terms and conditions thereof. PAS shall, and shall cause its
  Subsidiaries and Affiliates, and will use its best efforts to ensure their
  respective officers, directors, employees, investment bankers, attorneys,
  accountants and other agents to, immediately cease and cause to be
  terminated all discussions and negotiations that have taken place prior to
  the date hereof, if any, with any Persons conducted heretofore with respect
  to any Acquisition Proposal. As used in this Agreement, "Acquisition
  Proposal" shall mean any of the following (other than the transactions
  contemplated hereunder) involving PAS or any of its Subsidiaries: (i) any
  merger, consolidation, share exchange, recapitalization, business
  combination, or other similar transaction; (ii) any sale, lease exchange,
  mortgage, pledge, transfer or other disposition of 10% or more of the
  assets of PAS and its Subsidiaries, taken as a whole, in a single
  transaction or series of transactions; (iii) any tender offer or exchange
  for or other purchase of 10% or more of the outstanding shares of the
  capital stock of PAS or the filing of a registration statement under the
  Securities Act in connection therewith; or (iv) any public announcement of
  a proposal, plan or intention to do any of the foregoing. Nothing contained
  in this Section 7.1(e) shall prohibit PAS or its Board of Directors from
  taking and disclosing to its stockholders a position with respect to a
  tender offer by a third party pursuant to Rules 14d-9 and 14e-2(a)
  promulgated under the Exchange Act or making such disclosure as may be
  required by applicable law.
 
    (f) No Spacecraft Acquisitions, Investments or Capital
  Expenditures. Except as listed on Schedule 7.1(f), PAS shall not, and shall
  not permit any of its Subsidiaries to (i) acquire or agree to acquire any
  satellite or other spacecraft which PAS has not, on the date of this
  Agreement, previously agreed in writing to acquire, or (ii) make one or
  more investments or capital expenditures exceeding $35,000,000 in the
  aggregate in any twelve month period for all such investments or
  expenditures that occur from the date hereof; provided, however, that PAS
  may (A) replace any satellite lost in a launch or in orbit, (B) continue
  capital programs now underway as described on Schedule 7.1(f), plus
  additional expenses solely for change orders of up to 10% of the progress
  payments on each satellite remaining to be paid as of the date hereof, and
  (C) purchase such terrestrial equipment as necessary to supply customers in
  the ordinary course in connection with leases of transponder capacity by
  such customers. Notwithstanding the foregoing, PAS shall not, and shall not
  permit any of its Subsidiaries to provide financing for, make any
  additional investment in, or make any capital expenditure for the benefit
  of, any business engaged in DTH Services unless such financing, investment
  or expenditure is ancillary to the sale or lease of, or other provision of
  service or capacity via, transponders. As used in this Agreement, "DTH
  Services" means any video, audio, data or other information services
  provided by satellite and intended for direct reception by the general
  public.
 
    (g) No Dispositions. Other than as contemplated hereby and other than
  dispositions in the ordinary course of business consistent with past
  practice which are not material in the aggregate to PAS and its
  Subsidiaries, taken as a whole, PAS shall not, and shall not permit any of
  its Subsidiaries to, sell, pledge, lease, dispose of, encumber or otherwise
  authorize the sale, disposition, grant, encumbrance, lease (whether such
  lease is an operating or capital lease) of any of its assets.
 
    (h) No Dissolution, Etc. Except as otherwise permitted or contemplated by
  this Agreement, PAS shall not authorize, recommend, propose or announce an
  intention to adopt a plan of complete or partial liquidation or dissolution
  of PAS or any of its Significant Subsidiaries. As used in this Agreement,
  the term "Significant Subsidiary" has the meaning assigned to it in
  Regulation S-X under the Exchange Act.
 
                                     A-40

    (i) Other Actions. PAS will not voluntarily take, and will not permit any
  of its Subsidiaries voluntarily to take or agree or commit voluntarily to
  take, any action that results in any of PAS' representations or warranties
  hereunder being untrue in any material respect or in any of PAS' covenants
  hereunder or any other conditions to the Asset Contribution, the Univisa
  Contribution or the Merger not being satisfied in all material respects.
  Notwithstanding the foregoing, no action permitted by this Section 7.1 or
  contemplated by this Agreement shall be construed to have caused a breach
  of a representation or warranty contained herein.
 
    (j) Certain Employee Matters. Except as described on Schedule 7.1(j), PAS
  and its Subsidiaries shall not: (A) grant any increases in the compensation
  or fringe benefits of any of its directors, officers, or key employees; (B)
  pay or agree to pay any pension, retirement allowance, severance,
  termination or other employee benefit not required or contemplated by any
  of the existing PAS ERISA Plans or PAS Benefit Arrangements as in effect on
  the date hereof to any such director, officer or key employee, whether past
  or present; (C) other than with respect to new hires consistent with past
  practice enter into any new, or materially amend any existing, employment
  or severance or termination agreement with any such director, officer or
  key employee; or (D) establish, adopt, enter into, or amend any collective
  bargaining, bonus, profit sharing, thrift, compensation, stock option,
  restricted stock, pension, retirement, savings, welfare, deferred
  compensation, employment, termination, severance or other employee benefit
  plan, agreement, trust, fund, policy or arrangement for the benefit or
  welfare of any directors, officers or current or former employees, except
  in each case (i) to the extent required by applicable law or regulation,
  (ii) pursuant to collective bargaining agreements as in effect on the date
  of this Agreement, (iii) for cash bonuses in lieu of options not to exceed
  $5,000,000 in the aggregate, (iv) normal bonuses and normal increases to
  officers and key employees consistent with past practice or other
  agreements which PAS believes are necessary for the continued conduct of
  PAS' business in the ordinary course, or (v) for amendments to PAS ERISA
  Plan(s) or PAS Benefits Arrangement(s) which have been disclosed to HCI
  prior to the execution of this Agreement or which would not materially
  increase the cost of benefits to PAS and its Subsidiaries, taken as a
  whole, in the aggregate.
 
    (k) Indebtedness. Except as set forth on Schedule 7.1(k), and except for
  borrowing in the ordinary course of business consistent with past practices
  under its existing credit facilities or arrangements, PAS shall not, and
  shall not permit any of its Subsidiaries to, assume, incur or pre-pay any
  indebtedness for borrowed money or guarantee any such indebtedness or issue
  or sell any debt securities or warrants or rights to acquire any debt
  securities of such party or any of its Subsidiaries or guarantee any debt
  securities of others or enter into any lease other than in the ordinary
  course (whether such lease is an operating or capital lease), or create any
  mortgages, liens, security interests or other encumbrances on the property
  of PAS or any of its Subsidiaries in connection with any indebtedness
  thereof, or enter into any "keep well" or other agreement or arrangement to
  maintain the financial condition of another person; provided that PAS may
  enter into any such "keep well" agreement or arrangement if the payment of
  the full amount of the obligation represented by such agreement could then
  be made as an investment under Section 7.1(f).
 
    (l) Agreements. Except as permitted by Section 7.1(f) or as otherwise
  contemplated by this Agreement, PAS shall not, and shall not permit any of
  its Subsidiaries to, enter into, materially modify, rescind, terminate,
  waive, release or otherwise amend any of the terms or provisions of any
  Material Contract, other than in the ordinary course of business consistent
  with past practice.
 
    (m) Accounting. PAS shall not, and shall not permit any of its
  Subsidiaries to, take any action, other than in the ordinary course of
  business, consistent with past practice or as required by the SEC or by
  law, to effect any material change in any of its current accounting
  policies, procedures and practices.
 
    (n) Payment of Claims. PAS shall not, and shall not permit any of its
  Subsidiaries to, pay, discharge or satisfy any material claims, liabilities
  or obligations (absolute, accrued, asserted, unasserted, contingent or
  otherwise), other than such payment, discharge or satisfaction in the
  ordinary course of business and consistent with past practice.
 
    (o) Waivers and Payments. PAS shall not, and shall not permit any of its
  Subsidiaries to, other than in the ordinary course of business and
  consistent with past practice, waive any rights of substantial value or
 
                                     A-41
<PAGE>
 
  make any payment, direct or indirect, of any material liability before the
  same comes due in accordance with its terms, except to the extent (and only
  to the extent) to which PAS receives fair value in exchange for such waiver
  or payment.
 
    (p) Insurance. PAS shall not and shall not permit any of its Subsidiaries
  to, fail to maintain its existing insurance coverage of all types in effect
  or, in the event any such coverage shall be terminated or lapse, to the
  extent available at reasonable cost, procure substantially similar
  substitute insurance policies which in all material respects are in at
  least such amounts and against such risks as are currently covered by such
  policies. Notwithstanding the foregoing, PAS shall not renew any spacecraft
  insurance policy other than at the best available rate after competitive
  bidding.
 
    (q) Affiliate Transactions. PAS shall not, and shall not permit any of
  its Subsidiaries to, engage in any transaction with, or enter into any
  agreement, arrangement, or understanding with, directly or indirectly, any
  of such entity's affiliates (as defined in Rule 12(b)-2 under the Exchange
  Act) which involves the transfer of consideration or has a financial impact
  on such entity, other than pursuant to such agreements, arrangements, or
  understandings (i) existing on the date of this Agreement (all of which
  such agreements are considered to be Material Contracts for purposes of
  Section 5.16), (ii) which are done on terms that the Board of Directors of
  PAS determines in good faith to be equal to, or more favorable to PAS, than
  the terms that PAS would be able to obtain from third parties in similar
  transactions and/or for similar goods or services or (iii) which are
  permitted by Section 7.1(o) hereof including PAS and any of its
  Subsidiaries.
 
    (r) PAS Permits. Except for Permits which lapse or expire due to ordinary
  course changes in the business of PAS, PAS shall not surrender, allow to
  expire or be terminated, modify adversely, forfeit, or fail to renew or
  extend under regular terms any of the PAS Permits issued by the FCC (other
  than those related to PAS Ground Stations) or give the FCC or other
  Government Entity with jurisdiction any grounds to institute any proceeding
  for the revocation, suspension, or adverse modification of any PAS Permit
  issued by the FCC. Should the FCC or other Government Entity with
  jurisdiction institute any proceedings for the suspension, revocation or
  adverse modification of any of such PAS Permits, PAS shall use commercially
  reasonable efforts to promptly contest such proceedings and to seek to have
  such proceedings terminated in a manner that is favorable to PAS.
 
    (s) Construction Permits and Applications. PAS will use commercially
  reasonable efforts to maintain each FCC construction Permit (if any) listed
  on Schedule 5.6 in effect until the applicable construction projects are
  complete and will not, by act or omission, cause, or fail to use
  commercially reasonable efforts to avoid having, any pending FCC
  application listed on Schedule 5.6 to be dismissed or denied, except where
  (i) the loss of such Permit or pending application would not have a
  material adverse effect on PAS and its Subsidiaries, taken as a whole or
  (ii) the maintenance of any such Permit would require an expenditure which
  would be in violation of subsection (f) above.
 
    (t) Interference. PAS shall use commercially reasonable efforts to
  protect the transmissions to and from the PAS Satellites and the PAS Ground
  Stations from interference from other radio communications facilities
  (existing or proposed), to the extent that such interference is prohibited
  by FCC Rules or inconsistent with rights accorded the PAS Satellites under
  the ITU's Radio Regulations and shall promptly notify HCI of any actual or
  threatened interference. As used in this Agreement, "FCC Rules" means,
  collectively, the Communications Act of 1934, as amended, or any successor
  statute, and the rules, regulations, orders and policies of the FCC
  promulgated thereunder.
 
    (u) No Restrictive Agreements. Neither PAS nor any of its Subsidiaries
  shall enter into any contract, agreement, commitment, arrangement, lease
  (including with respect to personal property), policy or other instrument
  that (i) does not expire by the later of one (1) year after the date hereof
  or six (6) months after the Closing or (ii) is not subject to termination
  by PAS upon less than six months written notice to the other party thereto,
  which in either case materially restricts or limits PAS' or such
  Subsidiary's right to conduct its business or compete, including, without
  limitation, any restriction on its ability to sell, lease or otherwise
  provide services from available transponder capacity to any person or
  entity for any purpose at any orbital location and in any frequency band,
  any geographical market segment, product line or other industry limitation,
  or any exclusive or sole supply or vendor arrangement or agreement. Nothing
  in this Section
 
                                     A-42
<PAGE>
 
  7.1(u) shall preclude or require PAS or any of its Subsidiaries from
  entering into agreements containing most favored nation provisions, options
  for additional services or capacity, rights of negotiation, or similar
  provisions, in each case in the ordinary course of business.
 
    (v) Certain Other Agreements. PAS shall not, and shall not permit any of
  its Subsidiaries to, enter into any contract, commitment or arrangement,
  whether written or oral, to do any of the acts prohibited by this Section
  7.1 or to authorize, recommend, propose or announce an intention to do the
  same. Notwithstanding the foregoing, PAS may enter into an agreement with
  the landlord of the part of the PAS Leased Property located in Greenwich,
  Connecticut to increase the square footage of such leased space by
  approximately 9,000 square feet on commercially reasonable terms and
  conditions, and PAS may enter into the lease agreement described on
  Schedule 5.18(d) on commercially reasonable terms and conditions.
 
  7.2 Interim Operations of the Galaxy Business. Except as expressly
contemplated or permitted by this Agreement or any of the Related Agreements,
or to the extent that PAS shall otherwise consent in writing, during the
period from the date of this Agreement and continuing until the Closing Date,
HCI and Galaxy agree as to the Galaxy Business that:
 
    (a) Ordinary Course. HCI shall cause each of the Contributed Entities to
  carry on the Galaxy Business in the usual, regular and ordinary course in
  substantially the same manner as heretofore conducted and to use
  commercially reasonable efforts, to the extent necessary to conduct normal
  operations, to preserve intact its present business organizations, to keep
  available the services of its current officers and Galaxy Employees and to
  preserve its relationships with customers, suppliers and others having
  business dealings with it to the end that its goodwill and ongoing business
  shall not be impaired in any material respect at the Closing Date. For the
  avoidance of doubt, it is understood that, subject to the limitations on
  investment, dispositions and incurrence of indebtedness in subsections (f),
  (g) and (k) below, the pursuit of and consummation by the Contributed
  Entities of strategic partnerships, joint ventures, acquisitions and
  similar activities and investments shall be considered to be in the
  "ordinary course" for the Contributed Entities if, in each case, such
  activities and investments are ancillary to the sale or lease of, or the
  provision of service or capacity via, transponders by the Contributed
  Entities.
 
    (b) Dividends; Changes in Capital Stock. None of the Contributed Entities
  shall: (i) declare, set aside or pay any dividends on or make other
  distributions (whether in cash, securities or property or any combination
  thereof) in respect of any class or series of its capital stock, except for
  non-cash dividends in respect of preferred stock, or cash dividends or
  distributions paid on or with respect to the capital stock of a wholly
  owned Subsidiary; (ii) split, combine, subdivide or reclassify any of its
  capital stock or issue or authorize or propose the issuance of any other
  securities in respect of, in lieu of or in substitution for shares of its
  capital stock; or (iii) repurchase, redeem or otherwise acquire, or permit
  any Subsidiary to purchase or otherwise acquire, any shares of the capital
  stock or other securities of HCI or any of its Affiliates.
 
    (c) Issuance of Securities. Other than as provided or allowed herein and
  except as set forth on Schedule 7.2(c) or pursuant to the exercise of
  Options, none of the Contributed Entities shall issue, pledge or sell, or
  authorize the issuance, pledge or sale of additional shares of capital
  stock of any class, or securities convertible into capital stock of any
  class, or any rights, warrants or options to acquire any convertible
  securities or capital stock, or any other securities in respect of, in lieu
  of, or in substitution for, shares of common stock outstanding on the date
  hereof or (ii) amend, waive or otherwise modify any of the terms of any
  option, warrant or stock option plan of it. Except as otherwise
  contemplated hereby, HCI will make no transfer of the capital stock of any
  of the Contributed Entities, whether to an Affiliate or otherwise.
 
    (d) Governing Documents. None of the Contributed Entities shall amend or
  propose to amend their respective Certificates or Articles of Incorporation
  or Bylaws.
 
    (e) No Spacecraft Acquisitions, Investments or Capital
  Expenditures. Except as listed on Schedule 7.2(e), none of the Contributed
  Entities shall (i) acquire or agree to acquire any satellite or other
  spacecraft which a Contributed Entity has not, on the date of this
  Agreement, previously agreed in writing to acquire, or (ii) except as
  required pursuant to Section 7.24, make one or more investments or capital
  expenditures exceeding $35,000,000 in the aggregate in any twelve month
  period for all such investments or expenditures
 
                                     A-43
<PAGE>
 
  that occur from the date hereof; provided, however, that any Contributed
  Entity may replace any satellite lost in a launch or in orbit.
 
    (f) No Dispositions. Other than as contemplated hereby and other than
  dispositions in the ordinary course of business consistent with past
  practice which are not material in the aggregate to the Galaxy Business,
  HCI shall not, and shall not permit any of its Subsidiaries to, sell,
  pledge, lease, dispose of, encumber or otherwise authorize the sale,
  disposition, grant, encumbrance, lease (whether such lease is an operating
  or capital lease) of any of the assets related to the Galaxy Business.
 
    (g) No Dissolution, Etc. Except as otherwise permitted or contemplated by
  this Agreement, HCI shall not authorize, recommend, propose or announce an
  intention to adopt a plan of complete or partial liquidation or dissolution
  of any of HCI or any of the Contributed Entities.
 
    (h) Other Actions. None of the Hughes Parties will voluntarily take, or
  permit any of their Subsidiaries voluntarily to take or agree or commit
  voluntarily to take, any action that results in any of the Hughes Parties'
  representations or warranties hereunder being untrue in any material
  respect or in any of the Hughes Parties' covenants hereunder or any other
  conditions to the Asset Contribution, the Univisa Contribution or the
  Merger not being satisfied in all material respects. Notwithstanding the
  foregoing, no action permitted by this Section 7.2 or contemplated by this
  Agreement shall be construed to have caused a breach of a representation or
  warranty contained herein.
 
    (i) Certain Employee Matters. Except as described on Schedule 7.2(i), HCI
  shall not permit any of the Contributed Entities or any of their
  Subsidiaries to: (A) grant any increases in the compensation or fringe
  benefits of any of its directors, officers, or key employees; (B) pay or
  agree to pay any pension, retirement allowance, severance, termination or
  other employee benefit not required or contemplated by any of the existing
  Galaxy ERISA Plans or Galaxy Benefit Arrangements as in effect on the date
  hereof to any such director, officer or key employee, whether past or
  present; (C) other than with respect to new hires consistent with past
  practice enter into any new, or materially amend any existing, employment
  or severance or termination agreement with any such director, officer or
  key employee; or (D) establish, adopt, enter into, or amend any collective
  bargaining, bonus, profit sharing, thrift, compensation, stock option,
  restricted stock, pension, retirement, savings, welfare, deferred
  compensation, employment, termination, severance or other employee benefit
  plan, agreement, trust, fund, policy or arrangement for the benefit or
  welfare of any directors, officers or current or former employees, except
  in each case (i) to the extent required by applicable law or regulation,
  (ii) pursuant to collective bargaining agreements as in effect on the date
  of this Agreement, (iii) for normal increases and bonuses to officers and
  key employees consistent with past practice or other agreements which HCI
  believes are necessary for the continued conduct of the Galaxy Business in
  the ordinary course, or (iv) for amendments to Galaxy ERISA Plan(s) or
  Galaxy Benefit Arrangement(s) which have been disclosed to PAS prior to the
  execution of this Agreement or which would not materially increase the cost
  of benefits to the Galaxy Business, in the aggregate.
 
    (j) Indebtedness. Except (i) as set forth on Schedule 7.2(j) and (ii) as
  incurred, guaranteed or created in connection with financing the
  transactions contemplated hereby, HCI shall not permit any of the
  Contributed Entities or any of their Subsidiaries to assume, incur or pre-
  pay any indebtedness for borrowed money or guarantee any such indebtedness
  or issue or sell any debt securities or warrants or rights to acquire any
  debt securities of such party or any of its Subsidiaries or guarantee any
  debt securities of others or enter into any lease other than in the
  ordinary course (whether such lease is an operating or capital lease), or
  create any mortgages, liens, security interests or other encumbrances on
  the property of the Galaxy Business in connection with any indebtedness
  thereof, or enter into any "keep well" or other agreement or arrangement to
  maintain the financial condition of another person; provided that any of
  the Contributed Entities may enter into any such "keep well" agreement or
  arrangement if the payment of the full amount of the obligation represented
  by such agreement could then be made under Section 7.2(e).
 
    (k) Agreements. Except as permitted by Section 7.2(e) or as otherwise
  contemplated by this Agreement, HCI shall not permit any of the Contributed
  Entities or any of their Subsidiaries to enter into, materially modify,
  rescind, terminate, waive, release or otherwise amend any of the terms or
  provisions of any Material Contract, other than in the ordinary course of
  business consistent with past practice.
 
                                     A-44
<PAGE>
 
    (l) Accounting. HCI shall not permit any of the Contributed Entities or
  any of their Subsidiaries to take any action, other than in the ordinary
  course of business, consistent with past practice or as required by the SEC
  or by law, to effect any material change in any of its current accounting
  policies, procedures and practices.
 
    (m) Payment of Claims. HCI shall not permit any of the Contributed
  Entities or any of their Subsidiaries to pay, discharge or satisfy any
  material claims, liabilities or obligations (absolute, accrued, asserted,
  unasserted, contingent or otherwise), other than such payment, discharge or
  satisfaction in the ordinary course of business and consistent with past
  practice.
 
    (n) Waivers and Payments. HCI shall not permit any of the Contributed
  Entities or any of their Subsidiaries to, other than in the ordinary course
  of business and consistent with past practice, waive any rights of
  substantial value or make any payment, direct or indirect, of any material
  liability before the same comes due in accordance with its terms, except to
  the extent (and only to the extent) to which HCI or any of the Contributed
  Entities receives equivalent value in exchange for such waiver or payment.
 
    (o) Insurance. HCI shall not permit any of the Contributed Entities or
  any of their Subsidiaries to fail to maintain its existing insurance
  coverage of all types in effect with respect to the Galaxy Business or, in
  the event any such coverage shall be terminated or lapse, to the extent
  available at reasonable cost, procure substantially similar substitute
  insurance policies which in all material respects are in at least such
  amounts and against such risks as are currently covered by such policies.
  Notwithstanding the foregoing, HCI shall not permit any of the Contributed
  Entities to renew any spacecraft insurance policy other than at the best
  available rate after competitive bidding.
 
    (p) Affiliate Transactions. Except as set forth on Schedule 7.2(p), HCI
  shall not permit any of the Contributed Entities or any of their
  Subsidiaries to engage in any transaction with, or enter into any
  agreement, arrangement, or understanding relating to the Galaxy Business
  with, directly or indirectly, any of such entity's affiliates (as defined
  in Rule 12(b)-2 under the Exchange Act) which involves the transfer of
  consideration or has a financial impact on such entity, other than pursuant
  to such agreements, arrangements, or understandings (i) existing on the
  date of this Agreement (all of which such agreements are considered to be
  Material Contracts for purposes of Section 6.15) (ii) which are done on
  terms that the Board of Directors of the relevant Contributed Entity
  determines in good faith to be equal to, or more favorable to such
  Contributed Entity, than the terms such entity would be able to obtain from
  third parties in similar transactions and/or for similar goods or services
  or (iii) which are permitted by Section 7.2(n) hereof involving HCI or any
  of the Contributed Entities and any of their respective Subsidiaries.
 
    (q) Galaxy Permits. Except for (i) Permits listed on Schedule 6.6(b)
  which are indicated on such schedule to be subject to termination by the
  FCC upon the launch of another satellite into the location where certain
  Galaxy Satellites now are operating, and (ii) Permits which lapse or expire
  due to ordinary course changes in the Galaxy Business, HCI shall not permit
  any of the Contributed Entities or any of their Subsidiaries to surrender,
  allow to expire or be terminated, modify adversely, forfeit, or fail to
  renew or extend under regular terms any of the Galaxy Permits issued by the
  FCC (other than those related to Galaxy Ground Stations), or give the FCC
  or other Government Entity with jurisdiction any grounds to institute any
  proceeding for the revocation, suspension, or adverse modification of any
  Galaxy Permit issued by the FCC. Should the FCC or other Government Entity
  with jurisdiction institute any proceedings for the suspension, revocation
  or adverse modification of any such Galaxy Permits, HCI shall cause the
  Contributed Entity to use commercially reasonable efforts to promptly
  contest such proceedings and to seek to have such proceedings terminated in
  a manner that is favorable to such entities.
 
    (r) Construction Permits and Applications. HCI shall cause the
  Contributed Entity to use commercially reasonable efforts to maintain each
  FCC construction Permit (if any) listed on Schedule 6.6(b) in effect until
  the applicable construction projects are complete and will use commercially
  reasonable efforts to avoid having any pending FCC application listed on
  Schedule 6.6(b) be dismissed or denied, except where (i) the loss of such
  Permit or pending application would not have a material adverse effect on
  the Galaxy Business or (ii) the maintenance of any such Permit would
  require an expenditure which would be in violation of subsection (e) above;
  provided, however, that Galaxy may, prior to or in connection with the
 
                                     A-45
<PAGE>
 
  Closing, amend the applications currently pending before the FCC for the
  Galaxy/Spaceway system in order to (i) make HCI or one of its Affiliates
  the applicant for Ka-band satellites at the following orbital locations:
  49(degrees)W, 99(degrees)W, 101(degrees)W, 25(degrees)E, 54(degrees)E,
  101(degrees)E, 111(degrees)E and 164(degrees)E, and (ii) make Newco the
  applicant for the rest of the BSS and Ka-band satellites sought in such
  application.
 
    (s) Interference. HCI shall cause the Contributed Entities to use their
  commercially reasonable efforts to protect the transmissions to and from
  the Galaxy Satellites and the Galaxy Ground Stations from interference from
  other radio communications facilities (existing or proposed), to the extent
  that such interference is prohibited by FCC Rules or inconsistent with
  rights accorded the Galaxy Satellites under the ITU's Radio Regulations and
  shall promptly notify PAS of any actual or threatened interference.
 
    (t) No Restrictive Agreements. None of the Contributed Entities shall
  enter into any contract, agreement, commitment, arrangement, lease
  (including with respect to personal property), policy or other instrument
  that (i) does not expire by the later of one (1) year after the date hereof
  or six (6) months after the Closing or (ii) is not subject to termination
  by such entity upon less than six months written notice to the other party
  thereto, which in either case materially restricts or limits such entity's
  ability to conduct its business or compete, including, without limitation,
  any restriction on its right to sell, lease or otherwise provide services
  from available transponder capacity to any person or entity for any purpose
  at any orbital location and in any frequency band, any geographical, market
  segment, product line or other industry limitation, or any exclusive or
  sole supply or vendor arrangement or agreement. Nothing in this Section
  7.2(t) shall preclude or require any Contributed Entity from entering into
  agreements containing most favored nation provisions, options for
  additional services or capacity, rights of negotiation, or similar
  provisions, in each case in the ordinary course of business.
 
    (u) Additional Property. HCI shall cause one of the Contributed Entities
  to acquire a leasehold interest, for a term of at least 30 years and
  otherwise on commercially reasonable terms and conditions, in and to the
  real property on which are located the ground station and other
  improvements currently owned by HCSS located off of East Garton Road in
  Castle Rock, Colorado. In addition, such lease shall provide that any
  domestic or international satellite arc shall not be blocked by any
  improvement or structure on any adjoining land owned or controlled by HCSS,
  its successors and assigns. HCI shall cause one of the Contributed Entities
  to continue to negotiate, on commercially reasonable terms, for the
  acquisition of the fee interest of Texaco Exploration and Production, Inc.
  in and to approximately 752 acres located off Telegraph Road in Fillmore,
  California. In connection with the above mentioned acquisitions, PAS and
  its counsel shall be delivered copies of any draft agreements and, from
  time to time, shall be advised of the status of these matters. HCSS shall
  use best efforts (not involving the payment of money) to obtain customary
  non-disturbance agreements from the superior lessors of the lease described
  in item #2 of Schedule 6.17(b). Notwithstanding the foregoing, HCSS may
  enter into the lease agreement described on Schedule 6.17(d) on
  commercially reasonable terms and conditions.
 
    (v) Certain Other Agreements. HCI shall not and shall not permit any of
  the Contributed Entities or any of their Subsidiaries to enter into any
  contract, commitment or arrangement, whether written or oral, to do any of
  the acts prohibited by this Section 7.2 or to authorize, recommend, propose
  or announce an intention to do the same.
 
  7.3 Interim Operations of Newco.
 
  (a) Except as contemplated by this Agreement, or with the prior written
consent of PAS, during the period from the date of this Agreement to the
Closing Date, Newco will conduct no operations and will preserve intact its
business organization. Without limiting the generality of the foregoing and
except as otherwise contemplated by this Agreement or in connection with the
financing of the cash portion of the consideration payable in the Univisa
Contribution and the Merger or the refinancing of indebtedness of Newco,
Galaxy or PAS, Newco will not, prior to the Closing Date, without the prior
written consent of PAS:
 
    (i) adopt any amendment to its Certificate of Incorporation or Bylaws;
  provided, that on or prior to the Closing Newco shall amend its Certificate
  of Incorporation in form and substance reasonably satisfactory to PAS, to
  provide for the protections set forth in Section 9.4(b) herein;
 
 
                                     A-46
<PAGE>
 
    (ii) issue, pledge or sell, or authorize the issuance, pledge or sale of
  additional shares of capital stock of any class, or securities convertible
  into capital stock of any class, or any rights, warrants or options to
  acquire any convertible securities or capital stock, or any other
  securities in respect of, in lieu of, or in substitution for, shares of
  common stock outstanding on the date hereof;
 
    (iii) declare, set aside or pay any dividend or other distribution
  (whether in cash, securities or property or any combination thereof) in
  respect of any class or series of its capital stock;
 
    (iv) authorize, recommend, propose or announce an intention to adopt a
  plan of complete or partial liquidation or dissolution;
 
    (v) take, or agree to commit to take, any action that would make any
  representation or warranty contained in Article VI hereof inaccurate in any
  respect at, or as of any time prior to, the Closing Date; or
 
    (vi) enter into a contract, commitment or arrangement to do any of the
  foregoing, or to authorize, recommend, propose or announce an intention to
  do any of the foregoing.
 
  7.4 Control of Galaxy and PAS. During the period from the date of this
Agreement and continuing until the Closing Date (the "Interim Period"),
control of the operations of PAS and its Subsidiaries shall remain with PAS
and control of the Galaxy Business shall remain with HCI and the Contributed
Entities. HCI agrees that neither it nor any of its Subsidiaries shall
control, direct, supervise, or attempt to control, direct or supervise, the
operations of PAS during this period. Likewise, the parties agree that neither
PAS nor any of its Subsidiaries shall control, direct, supervise, or attempt
to control, direct or supervise, the operations of the Galaxy Business during
the Interim Period. Notwithstanding anything in this Agreement to the
contrary, no action shall be taken hereunder constituting an assignment or
transfer of control of an FCC license, permit, authorization or application
requiring the prior consent or approval of the FCC without first obtaining
such consent or approval.
 
  7.5 Registration Statement and Proxy Statement/Prospectus. Promptly
following the date of this Agreement, HCI, Galaxy, Newco and PAS shall
cooperate and prepare, and PAS shall file with the SEC, the proxy statement
with respect to the meeting of the stockholders of PAS in connection with the
PAS Merger (the "Proxy Statement/Prospectus"), and HCI shall cause Newco to
file with the SEC one or more Registration Statements on appropriate forms
under the Securities Act and the Exchange Act with respect to the securities
of Newco issuable in connection with the Merger or in connection with the
financing of the cash portion of the consideration payable in the Univisa
Contribution and the Merger or the refinancing of indebtedness of Newco, the
Contributed Entities or PAS (each, a "Registration Statement"). The Proxy
Statement/Prospectus will be included in the Registration Statement filed with
respect to the shares of Newco Common Stock issuable in connection with the
Merger. The respective parties will cause the Proxy Statement/Prospectus and
each Registration Statement to comply as to form in all material respects with
the applicable provisions of the Securities Act, the Exchange Act and the
rules and regulations thereunder. Newco shall use commercially reasonable
efforts, and each of the Contributed Entities and PAS will cooperate with
Newco, to have each Registration Statement declared effective by the SEC as
promptly as practicable and to keep each Registration Statement effective as
long as is necessary to consummate the transactions contemplated hereunder.
The respective parties shall, as promptly as practicable, provide copies of
any written comments received from the SEC with respect to the Proxy
Statement/Prospectus and/or each Registration Statement to each other and
advise each other of any verbal comments with respect thereto received from
the SEC. Newco shall use commercially reasonable efforts to obtain, prior to
the effective date of each Registration Statement, all necessary state
securities law or "blue sky" permits or approvals required to carry out the
transactions contemplated by such Registration Statement and will pay all
expenses incident thereto. Newco agrees that the Proxy Statement/Prospectus
and each amendment or supplement thereto at the time of mailing thereof and at
the time of the meeting of stockholders of PAS, or, in the case of a
Registration Statement and each amendment or supplement thereto, at the time
it is filed and becomes effective, will not include an untrue statement of a
material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading; provided, however, that the
foregoing shall not apply to the extent that any such untrue statement of a
material fact or omission to state a material fact was made by Newco in
reliance upon and in conformity with written information concerning PAS
furnished to
 
                                     A-47
<PAGE>
 
Newco by PAS, specifically for use in the Proxy Statement/Prospectus. PAS
agrees that the written information concerning PAS provided by it for
inclusion in the Proxy Statement/Prospectus and each amendment or supplement
thereto, at the time of mailing thereof and at the time of the meeting of
stockholders of PAS, or, in the case of written information concerning PAS
provided by PAS for inclusion in a Registration Statement or any amendment or
supplement thereto, at the time it is filed and becomes effective, will not
include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. No amendment or supplement to the Proxy Statement/Prospectus will
be made by PAS or Newco without the approval of the other parties hereto,
which shall not be unreasonably withheld. Newco will advise PAS, promptly
after it receives notice thereof, of the time when a Registration Statement
has become effective or any supplement or amendment has been filed, the
issuance of any stop order, the suspension of the qualification of the Newco
Common Stock issuable in connection with the transactions contemplated hereby
for offering or sale in any jurisdiction, or any request by the SEC for
amendment of the Proxy Statement/Prospectus or a Registration Statement or
comments thereon and responses thereto or requests by the SEC for additional
information.
 
  7.6 PAS Stockholders' Meeting. PAS will, as soon as practicable following
the date of this Agreement, take all action necessary in accordance with
applicable law and its Certificate of Incorporation and Bylaws to promptly
call, give notice of, convene and hold a PAS stockholders meeting for the
purpose of voting on this Agreement and the transactions contemplated hereby.
The Board of Directors of PAS shall, subject to its fiduciary duties,
recommend this Agreement's approval by its stockholders and PAS shall take all
lawful reasonable action to solicit such approval, including, without
limitation, timely mailing of the Proxy Statement/Prospectus, subject to the
provisions of Section 7.1(e); provided, however, that nothing in this sentence
shall modify or eliminate PAS' absolute obligations in the prior sentence.
 
  7.7 Access to Information.
 
  (a) Each party (but as to the Hughes Parties, only in connection with the
Galaxy Business) shall (and shall cause each of its Subsidiaries to) afford to
the officers, employees, accountants, counsel, financing sources and other
representatives of each other party reasonable access, during normal business
hours during the period prior to the Closing Date, to all its properties,
books, contracts, commitments and records and those of its Subsidiaries
(including any tax returns or other tax related information pertaining to the
party providing such information and its Subsidiaries) and, during such
period, each party shall (and shall cause each of its Subsidiaries to) (but as
to the Hughes Parties, only in connection with the Galaxy Business) furnish
promptly to each other party (i) a copy of each report, schedule, registration
statement and other document filed or received by such party or any such
Subsidiary during such period pursuant to requirements of federal securities
laws and (ii) all other information concerning the business, properties and
personnel of such party or any such Subsidiary as any other party may
reasonably request (including any tax returns or other tax related information
pertaining to any party or its Subsidiaries, as the case may be); provided
that, as to competitively sensitive information such as pricing or customer
specific information, each party shall make such sensitive information
available only to the other parties' advisers, lawyers and accountants (who
shall maintain the confidentiality of such information consistent with the
past practices of the parties to this Agreement) but not to the other parties,
and, with respect to information protected by the attorney-client privilege,
neither party shall be obligated to make such information available to the
other party or its representatives. Each party agrees that it will not, and
will cause its representatives not to, use any information obtained pursuant
to this Section 7.7 for any purpose unrelated to the consummation of the
transactions contemplated by this Agreement.
 
  (b) A Confidentiality Agreement, dated as of July 19, 1996 between PAS and
HE (the "Confidentiality Agreement"), shall apply with respect to information
furnished thereunder or hereunder and any other activities contemplated
thereby.
 
  7.8 Confidentiality.
 
  (a) Preservation of Confidentiality. In connection with the negotiation of
this Agreement, the preparation for the consummation of the transactions
contemplated hereby and the performance of obligations hereunder,
 
                                     A-48
<PAGE>
 
each party acknowledges that it will have access to confidential information
relating to the other parties. The parties shall treat such information as
confidential, preserve the confidentiality thereof and not disclose such
information, except to their respective advisors and consultants in connection
with the transactions contemplated hereby. Each of the parties agrees to
maintain in confidence, and not to disclose to any third party, any ideas,
methods, developments, inventions, improvements and business plans and
information which are the confidential information of any other party. If,
however, confidential information is disclosed, the disclosing party shall
immediately notify each of the other parties in writing and take all steps
required to prevent further disclosure.
 
  (b) Property Right in Confidential Information. Until the Closing Date, all
confidential information shall remain the property of the party who originally
possessed such information. In the event of the termination of this Agreement
for any reason whatsoever, each party shall return to the other parties all
documents, work papers and other material (including all copies thereof)
obtained from such parties in connection with the transactions contemplated
hereby and will use commercially reasonable efforts, including, without
limitation, instructing its employees and others who have had access to such
information, to keep confidential and not to use any such information, unless
such information is now, or is hereafter disclosed, through no act or omission
of such party, in any manner making it available to the general public. If any
party is required by any Law or order to disclose any confidential
information, it shall provide the other parties with prompt notice of such
request so that such other parties may seek an appropriate protective order or
other appropriate remedy and/or waive compliance with the provisions of this
Agreement. If, in the absence of a protective order or other remedy or the
receipt of such a waiver, a party is nonetheless compelled by Law or order to
disclose confidential information, then such party may disclose that portion
of the confidential information which such Law or order requires to be
disclosed, provided that such party uses its reasonable efforts to preserve
the confidentiality of the information, whereupon such disclosure shall not
constitute a breach of this Agreement.
 
  (c) Termination of Agreement. Subject to any Law, each party hereto shall,
and shall cause their Subsidiaries, Affiliates and representatives who obtain
such information to, hold in confidence all such non-public information until
such time as such information is otherwise publicly available, and, if this
Agreement is terminated and if so requested by another party, each party and
its Affiliates will, and will cause their Subsidiaries, Affiliates and
representatives who obtain such information to, deliver to such other party
all documents, work papers and other material (including copies extracts and
summaries thereof) obtained by or on behalf of any of them directly or
indirectly as a result of this Agreement or in connection herewith, whether so
obtained before or after the execution hereof.
 
  7.9 Legal Conditions, Filings and Consents.
 
  (a) Each of the Hughes Parties and PAS will (i) cooperate with one another
in determining whether any actions or filings are required in connection with
obtaining any Government Entity approvals required to consummate the
transactions contemplated by this Agreement and the Univisa Contribution
Agreement (together with the "Collateral Agreements" thereunder), the
Principal Stockholders Agreement, the Newco Stockholders Agreement, the
Registration Rights Agreement, the Assurance Agreement, the Income Tax
Indemnification and Allocation Agreement and the DTH Option Purchase Agreement
(together, the "Related Agreements") (including, without limitation,
furnishing all information required under the HSR Act), (ii) cooperate with
one another in determining whether any actions, consents, approvals or waivers
are required to be obtained from any corporate or equivalent governing body of
any party, any of their Subsidiaries, or any stockholder of the foregoing, or
whether any actions, consents, approvals or waivers are required to be
obtained from any third parties, such as parties to any material contracts, in
connection with the consummation of the transactions contemplated by this
Agreement and the Related Agreements, (iii) endeavor in good faith to take all
such actions or make any such filings, furnish information required in
connection therewith, and seek in a timely manner to obtain any such actions,
consents, approvals or waivers and (iv) promptly cooperate with and furnish
information to each other in connection with any such requirements imposed
upon any of them or any of their Subsidiaries in connection with the Univisa
Share Contribution and the Merger and the other transactions contemplated by
this Agreement and the Related Agreements. Without limiting the generality or
effect of the foregoing, each of
 
                                     A-49
<PAGE>
 
the Hughes Parties and PAS will, and will cause its Subsidiaries to, take all
commercially reasonable actions necessary to obtain (and will cooperate with
each other in obtaining) in a timely manner any consent, authorization, order
or approval of, or any exemption by, any Government Entity or other public or
private third party, required to be obtained or made by such entity in
connection with the Asset Contribution, the Univisa Contribution, the Merger,
this Agreement, any Related Agreement or the taking of any action contemplated
hereby or thereby. Notwithstanding the foregoing, none of the parties shall be
obligated hereby to enter into any consent decree or settlement agreement in
order to resolve any such action.
 
  (b) Without limiting the generality of the foregoing, each party will, and
each such party will cause their respective Subsidiaries to, diligently take
or cooperate in the taking of all steps reasonably necessary or desirable and
proper to prosecute expeditiously all requisite applications of HCI, the
Contributed Entities and PAS to the FCC and all similar foreign agencies
seeking their consent to the transactions contemplated by this Agreement and
to obtain a determination by the FCC that the grant of the applications made
by HCI, the Contributed Entities and/or PAS to the FCC including those
described in Section 7.9(c) below will serve the public interest, convenience
and necessity. Each party will use commercially reasonable efforts to resolve
such objections, if any, which may be asserted with respect to the
transactions contemplated hereby and by all Related Agreements under any law.
In the event an administrative proceeding or suit is instituted challenging
the transactions contemplated hereby, each party will use commercially
reasonable efforts to resist or resolve such proceeding or suit consistent
with the terms of this Agreement. Each party will use commercially reasonable
efforts to take such action as may be required (i) by any Government Entity in
order to resolve such objections as it may have to the transactions
contemplated hereby or (ii) by any federal or state court of the United
States, in any suit brought by a private party or Government Entity
challenging the transactions contemplated hereby, in order to avoid the entry
of any order which has the effect of preventing the consummation of the
transactions contemplated hereby on terms consistent with the terms of this
Agreement to take any action that is likely to have a material adverse effect
on it.
 
  (c) Within fifteen (15) days after the date hereof, the parties will file
one or more requisite applications with the FCC requesting its written consent
to the transactions contemplated by this Agreement (collectively, the "FCC
Consent Application"). To the extent that any pending applications for Permits
have not been granted by the Closing Date, PAS, HCI or a Contributed Entity,
as the case may be, will immediately after closing, file all necessary
documents with the FCC or equivalent agencies to amend those pending
applications to reflect the consummation of the Asset Contribution, the
Univisa Contribution and the Merger. In addition, to the extent that the Asset
Contribution, the Univisa Contribution and the Merger will result in a change
in ownership or control of an applicant for a Galaxy FCC Permit or a PAS FCC
Permit that requires, under FCC Rules, that a major amendment be filed by that
applicant after the Closing Date, within fifteen (15) days after the date
hereof, HCI, a Contributed Entity or PAS, as appropriate, will file or cause
to be filed by one of its Affiliates all appropriate documents requesting that
the FCC exempt such a major amendment from any applicable "cut off" date and
will also file such requests for any other required waivers of the FCC's rules
and policies as to which the parties may agree. HCI, the Contributed Entities
and PAS shall coordinate with each other prior to making any filings
contemplated by this Section 7.9(c).
 
  (d) If and to the extent that any lease, license, contract, commitment or
other agreement, including, without limitation, transponder lease agreements,
which would otherwise be included within the definition of "Galaxy Assets," or
any claim, right or benefit arising thereunder or resulting therefrom, is not
capable of being transferred or conveyed to Newco in the Asset Contribution
without the approval, consent or waiver of the other party thereto, and such
approval, consent or waiver has not been obtained prior to the Closing, or if
such transfer or conveyance would constitute a breach thereof, Galaxy or HCSS,
as the case may be, shall hold such asset for the exclusive benefit of PAS and
shall either obtain such consent or approval or provide PAS with the rights
and benefits of the affected lease, license, contract, commitment, or other
agreement for the term of such lease, license, contract, commitment or other
agreement; provided that PAS shall assume the obligations and burdens
thereunder.

  7.10 Indemnification and Insurance for Directors and Officers.
 
  (a) From and after the Closing Date all rights to indemnification now
existing in favor of individuals who at or prior to the Closing Date were
directors or officers of any of the Contributed Entities, Newco or PAS or any
of their respective Subsidiaries as set forth in their respective
organizational documents shall survive the Asset Contribution, the Univisa
Contribution and the Merger with respect to matters existing or occurring at
or prior to the Closing Date and shall continue in full force and effect for a
period of five years following the Closing Date.
 
  (b) Each of HCI, the Contributed Entities, Newco and PAS shall, and from and
after the Closing Date, Newco shall indemnify, defend and hold harmless each
person who is now, or has been at any time prior to the date hereof or who
becomes prior to the Closing Date, an officer or director of HCI, any
Contributed Entity, Newco or PAS or any of their respective Subsidiaries (each
individually an "Indemnified Person" and, collectively, the "Indemnified
Persons") against all losses, claims, damages, costs, expenses (including
attorneys' fees and expenses), liabilities or judgments or amounts that are
paid in settlement with the approval of the Indemnified Person (which approval
shall not be unreasonably withheld) as a result of or in connection with any
threatened or actual claim, action, suit, proceeding or investigation based in
whole or in part on or arising in whole or in part out of the fact that such
person is or was a director or officer of HCI, any Contributed Entity, Newco
or PAS or any of their respective Subsidiaries or out of or in connection with
activities in such capacity, whether pertaining to any matter existing or
occurring at or prior to the Closing Date and whether asserted or claimed
prior to, or at or after, the Closing Date ("Indemnified Liabilities"),
including all Indemnified Liabilities based in whole or in part on, or arising
in whole or in part out of, or pertaining to this Agreement or the
transactions contemplated hereby, in each case to the full extent a
corporation is permitted under the corporate law of the state in which it is
incorporated to indemnify any such person and, without limiting the generality
or effect of the foregoing, to the fullest extent provided in the respective
organizational documents of HCI, the Contributed Entities, Newco and PAS and
their respective Subsidiaries as in effect on the date hereof. Newco will pay
expenses in advance of the final disposition of any such action or proceeding
to each Indemnified Person to the fullest extent permitted by law and, without
limiting the generality or effect of the foregoing, to the fullest extent
provided in the respective organizational documents of HCI, the Contributed
Entities, Newco and PAS and their respective Subsidiaries as in effect on the
date hereof. Without limiting the generality or effect of the foregoing, in
the event any such claim, action, suit, proceeding or investigation is brought
against any Indemnified Persons (whether arising before or after the Closing
Date), (i) the Indemnified Persons may retain counsel reasonably satisfactory
to HCI or PAS, or from and after the Closing, Newco, and HCI or PAS shall, or
from and after the Closing, Newco shall, pay all fees and expenses of such
counsel for the Indemnified Persons promptly as statements therefore are
received and (ii) HCI or PAS shall, or from and after the Closing, Newco shall
use all reasonable efforts to assist in the vigorous defense of any such
matter, provided that none of HCI or PAS, or from and after the Closing, Newco
shall be liable for any settlement effected without its prior written consent,
which consent shall not unreasonably be withheld. Any Indemnified Party
wishing to claim indemnification under this Section 7.10, upon learning of any
such claim, action, suit, proceeding or investigation, shall notify HCI or
PAS, or from and after the Closing, Newco (but the failure so to notify shall
not relieve a party from any liability which it may have under this Section
7.10 except and only to the extent such failure materially prejudices such
party), and shall deliver to HCI or PAS, or from and after the Closing, Newco,
any undertaking contemplated or required by the corporate law of its state in
which it is incorporated. The Indemnified Persons as a group may retain only
one law firm to represent them with respect to each such matter unless there
is, in the opinion of counsel to an Indemnified Person, under applicable
standards of professional conduct, a conflict on any significant issue between
the positions of any two or more Indemnified Persons or unless different
defenses may exist. Each of HCI, the Contributed Entities, Newco and PAS
agrees that all rights to indemnification, including provisions relating to
advances of expenses incurred in defense of any action or suit, existing in
favor of the Indemnified Persons with respect to matters occurring through the
Closing Date, shall survive the Asset Contribution, the Univisa Contribution
and the Merger and shall continue in full force and effect for a period of not
less than four years from the Closing Date; provided, however, that all rights
to indemnification in respect of any Indemnified Liabilities asserted or made
within such period shall continue until the disposition of such Indemnified
Liabilities.
 
                                     A-51
<PAGE>
 
  (c) For a period of five years after the Closing Date, Newco will maintain
in effect or replace with equivalent policies of directors' and officers'
liability insurance as maintained by HCI, the Contributed Entities, Newco or
PAS, as the case may be, and their respective Subsidiaries with respect to
matters arising before the Closing Date, provided that Newco shall not be
required to pay an annual premium for such insurance in excess of 175% of the
last annual premium paid by HCI, a Contributed Entity, Newco or PAS, as the
case may be, prior to the date hereof, but in such case shall purchase as much
coverage as possible for such amount.
 
  (d) The provisions of this Section 7.10 are intended to be for the benefit
of, and shall be enforceable by, each Indemnified Person, his or her heirs and
personal representatives and shall be binding on HCI, each Contributed Entity,
Newco, PAS and on all successors and assigns thereof. In the event that Newco
or any of its successors or assigns (i) reorganizes or consolidates with or
merges into any other person and is not the resulting, continuing or surviving
corporation or entity in such consolidation or merger or (ii) liquidates,
dissolves or transfers all or substantially all of its properties and assets
to any person, then, and in each such case, proper provision will be made so
that the successors and assigns of such surviving corporations assume the
obligations set forth in this Section 7.10.
 
  7.11 Indemnification for Excluded and Contributed Liabilities.
 
  (a) HCI agrees to indemnify, defend and hold harmless Newco and each of its
Subsidiaries and their respective successors-in-interest against any losses,
claims, damages or liabilities, joint or several, arising out of or in
connection with any loss, claim, damage or liability against or pertaining to
any Hughes Party and/or their Affiliates (other than Newco and its
Subsidiaries) other than the Galaxy Liabilities, and HCI shall reimburse
Newco, each such Subsidiary and each such successor-in-interest (each, a
"Newco Indemnified Party") for any legal or any other expenses reasonably
incurred by any of them in connection with investigating or defending any such
loss, claim, damage or liability.
 
  (b) Newco agrees to indemnify, defend and hold harmless each of HCI and
Galaxy and their Subsidiaries after the Closing, and their respective
successors-in-interest against any losses, claims, damages or liabilities,
joint or several, arising out of or in connection with the Galaxy Liabilities
assumed by Newco pursuant to the terms hereof, and Newco shall reimburse HCI
or Galaxy, as the case may be, and each of their Subsidiaries and each such
successor-in-interest (each, a "Hughes Indemnified Party") for any legal or
any other expenses reasonably incurred by any of them in connection with
investigating or defending any such loss, claim, damage, liability or action.
 
  (c) Whenever any claim shall arise for indemnification under this Section
7.11, the Newco Indemnified Party or the Hughes Indemnified Party, as the case
may be (in either case, an "Indemnified Party"), shall promptly notify the
other party providing such indemnification (an "Indemnifying Party") in
writing of such claim and, when known, the facts constituting the basis for
such claim (in reasonable detail). Failure by any Indemnified Party to so
notify the Indemnifying Party shall not relieve such Indemnifying Party of any
liability hereunder except to the extent that such failure materially
prejudices such Indemnifying Party.
 
  (d) After the notice required by Section 7.11(c), if the Indemnifying Party
undertakes to defend any such claim, then the Indemnifying Party shall be
entitled, if it so elects, to take control of the defense and investigation
with respect to such claim and to employ and engage attorneys of its own
choice to handle and defend the same, at the Indemnifying Party's cost, risk
and expense, upon written notice to the Indemnified Party of such election,
which notice acknowledges such Indemnifying Party's obligation to provide
indemnification hereunder. The Indemnifying Party shall not settle any third-
party claim that is the subject of indemnification without the written consent
of the Indemnified Party, which consent shall not be unreasonably withheld;
provided, however, that the Indemnifying Party may settle a claim without the
Indemnified Party's consent if such settlement (i) makes no admission or
acknowledgement of liability or culpability with respect to such Indemnified
Party, (ii) includes a complete release of the Indemnified Party and (iii)
does not require the Indemnified Party to make any payment or forego or take
any action. The Indemnified Party shall cooperate in all reasonable respects
with the Indemnifying Party and its attorneys in the investigation, trial and
defense of any lawsuit or action with respect
 
                                     A-52
<PAGE>
 
to such claim and any appeal arising therefrom (including the filing in the
Indemnified Party's name of appropriate cross-claims and counterclaims). The
Indemnified Party may, at its own cost, participate in any investigation,
trial and defense of such lawsuit or action controlled by the Indemnifying
Party and any appeal arising therefrom.
 
  (e) If, after receipt of a claim notice pursuant to Section 7.11(c), the
Indemnifying Party does not undertake to defend any such claim, the
Indemnified Party may, but shall have no obligation to, contest any lawsuit or
action with respect to such claim and the Indemnifying Party shall be bound by
the result obtained with respect thereto by the Indemnified Party (including,
without limitation, the settlement thereof without the consent of the
Indemnifying Party). If there are one or more legal defenses available to the
Indemnified Party that conflict with those available to the Indemnifying
Party, the Indemnified Party shall have the right at the expense of the
Indemnifying Party to assume the defense of the lawsuit or action; provided,
however, that the Indemnified Party may not settle such lawsuit or action
without the consent of the Indemnifying Party, which consent shall not be
unreasonably withheld.
 
  (f) At any time after the commencement of defense of any lawsuit or action,
the Indemnifying Party may request the Indemnified Party to agree in writing
to the abandonment of such contest or to the payment or compromise by the
Indemnifying Party of such claim, whereupon such action shall be taken unless
the Indemnified Party determines that the contest should be continued and so
notifies the Indemnifying Party in writing within 15 days of receipt of such
request from the Indemnifying Party. If the Indemnified Party determines that
the contest should be continued, the Indemnifying Party shall be liable
hereunder only to the extent of the lesser of (i) the amount which the other
party(ies) to the contested claim had agreed to accept in payment or
compromise as of the time the Indemnifying Party made its request therefor to
the Indemnified Party or (ii) such amount for which the Indemnifying Party may
be liable with respect to such claim by reason of the provisions hereof.

  7.13 Publicity. So long as this Agreement is in effect, the parties will
consult with each other and will mutually agree prior to the issuance of any
press release or public announcement pertaining to this Agreement or the
Related Agreements or the transactions contemplated hereby or thereby,
including the Merger and the Asset Contribution, and shall not issue any such
press release or make any such public announcement or permit any of their
Subsidiaries to do the same prior to such consultation and agreement, except
as may be required by applicable law or by obligations pursuant to any listing
agreement with a national securities exchange (including the Nasdaq National
Market), in which case the party proposing to issue such press release or make
such public announcement shall use reasonable efforts to consult in good faith
with the other party before issuing any such press release or making any such
public announcement, except for the FCC filings and HSR filings contemplated
herein.
 
  7.14 Rule 145 Affiliates. At least 30 days prior to the Closing Date, PAS

all persons who PAS expects will be, at the time of PAS' stockholder's meeting
to consider the transactions contemplated by this Agreement, deemed to be
"affiliates" of PAS for purposes of Rule 145 under the Securities Act ("PAS
Affiliates"). PAS shall use its reasonable best efforts to cause each person
or entity who is identified as a PAS Affiliate to deliver to HCI on or prior
to the Closing Date an agreement substantially in the form of Exhibit H to
this Agreement.
 
  7.15 Supplemental Disclosure Schedules. Each of HCI, Galaxy and PAS shall

addition, from time to time prior to the Effective Time, each of HCI and PAS
will promptly deliver to the other parties such amended or supplemental
Schedules as may be necessary to make the Schedules accurate and complete in
all material respects as of the Closing Date; provided, however, that updating
the information contained on the Schedules shall not be deemed an amendment of
this Agreement unless the new information added to any such schedule reflects
changes or actions taken since the date of this Agreement that are permitted
under Section 7.1 (with respect to PAS) and Section 7.2 (with respect to
Galaxy). If not deemed an amendment, such supplement shall not have any effect
for the purpose of determining the satisfaction of the conditions set forth in
Article VIII of this Agreement.
 
  7.16 Newco Employee Benefits Arrangements.
 
  (a) Replacement of Retirement Plan.
 
    (i) The accrued benefits and liabilities, and assets attributable to such
  accrued benefits and liabilities, under the HE Non-Bargaining Retirement
  Plan, and the trust related thereto (the "HE Retirement Plan"), of
  participants in such plan who are actively employed by the Galaxy Business
  immediately prior to the Effective Time, who have not retired under the HE
  Retirement Plan as of the Effective Time and who become employees of Newco
  effective as of the Effective Time or within 90 days thereafter (the
  "Transferred Retirement Plan Participants") shall, unless otherwise agreed
  to by PAS and HE, be transferred to a new trust under a separate plan
  established by Newco for the Transferred Retirement Plan Participants and
  other Newco employees, as hereinafter set forth. Newco shall, with the
  cooperation of HE, use its best efforts to accomplish the transfer of the
  foregoing assets and liabilities.
 
    (ii) Effective as of the Effective Time, Newco shall, unless otherwise
  agreed to by PAS and HE, establish a separate plan (the "Newco Retirement
  Plan") which shall be qualified under Section 401(a) of the Code and a
  trust related thereto which shall be exempt from taxation under Section
  501(a) of the Code. The Newco Retirement Plan shall be a defined benefit
  cash balance plan, or other type of retirement plan agreed to by PAS and
  HE. To the extent permitted by applicable law, credit for past service with
  the Galaxy Business or PAS prior to the Effective Time shall be given under
  the Newco Retirement Plan for the purposes of vesting and eligibility to
  participate. The Newco Retirement Plan shall, unless otherwise agreed to by
  PAS and HE, contain provisions for future contributions at a rate of 3-3
  1/2% of the compensation of the participating Newco employees after the
  Effective Time.
 
 
                                     A-54
<PAGE>
 
    (iii) The transfer of assets and liabilities from the HE Retirement Plan
  to the Newco Retirement Plan shall be conditioned upon the receipt of
  requisite governmental approvals. Newco shall submit to the Internal
  Revenue Service a request for a determination letter as to the tax
  qualification and exempt status of the Newco Retirement Plan. Upon receipt
  by Newco and HE of such determination letter, or an opinion of counsel
  reasonably acceptable to HE and PAS, that the Newco Retirement Plan is tax
  qualified and exempt, HE and Newco shall file promptly with the Internal
  Revenue Service any required notice on Forms 5310-A regarding the transfer
  of assets and liabilities relating to the Transferred Retirement Plan
  Participants from the HE Retirement Plan to the Newco Retirement Plan.
  After proper notice has been given on Forms 5310-A without receiving an
  adverse response from the appropriate governmental agencies, the assets of
  the HE Retirement Plan transferable to such Newco Retirement Plan as
  provided herein shall be so transferred, but in no event later than 90 days
  after the Forms 5310-A have been filed with the Internal Revenue Service.
 
    (iv) No assets and liabilities shall be transferred unless the
  requirements of Section 414(l) of the Code are met with respect to the
  transfer. Assets to be transferred from the HE Retirement Plan to the Newco
  Retirement Plan shall be in cash. After the transfer of assets and
  liabilities, the payment of benefits accrued under the HE Retirement Plan
  prior to the Effective Time and payable to the Transferred Retirement Plan
  Participants shall be the sole responsibility of Newco.
 
    (v) The amount of plan assets to be transferred from the HE Retirement
  Plan to the Newco Retirement Plan shall be an amount determined by
  subtracting (B) from (A), where (A) as of the Effective Time equals the
  actuarially computed present value of all accrued benefits attributable to
  the Transferred Pension Plan Participants, determined on an ongoing plan
  basis employing the same actuarial assumptions as were used in determining
  plan funding for the most recently completed plan year, and where (B) is
  any benefit payment attributable to accrued benefits to be transferred to
  and assumed under the Newco Retirement Plan, made after the Effective Time
  and prior to the transfer of plan assets and accompanying liabilities. The
  transferred assets shall exclude any receivable contributions. The amount
  of assets transferred in connection with the foregoing accrued benefits and
  liabilities shall not be less than the assets necessary to fund the accrued
  benefits and liabilities that would be transferred using the appropriate
  plan termination assumptions of the Pension Benefit Guaranty Corporation
  ("PBGC") under Section 414(l) of the Code.
 
    (vi) The amount of the accrued benefits and liabilities and assets
  attributable thereto to be transferred from the HE Retirement Plan to the
  Newco Retirement Plan in accordance with this Section 7.3(b) shall be
  jointly determined by actuaries selected by Newco and HE. In the event of
  dispute between the actuaries selected by Newco and HE as to whether the
  actuarial calculations so determined are calculated in accordance with this
  Section 7.3(b), Newco and HE shall jointly select a third actuarial firm of
  national repute to review the calculation and the determination of the
  third actuarial firm shall be final and binding. In the event that Newco
  and HE are unable to select a third actuarial firm, an arbitrator shall
  appoint a third actuarial firm to make such determination, which
  appointment and determination shall be final and binding upon HE and Newco.
  Such arbitrator shall be appointed in accordance with the Commercial
  Arbitration Rules of the Los Angeles, California office of the American
  Arbitration Association. Newco shall pay the cost of the Newco's actuaries,
  HE shall pay the cost of HE's actuaries and, to the extent necessary, the
  cost of the third actuarial firm and arbitrator shall be shared equally
  between Newco and HE.
 
  (b) Replacement of Savings Plan.
 
    (i) The accounts and account balances and liabilities under the HE
  Salaried Employees' Thrift and Savings Plan and the trust related thereto
  (the "HE Savings Plan") and the Advantage Benefits Consultants Inc.
  Regional Prototype Defined Contribution Plan and Trust (the "PAS Savings
  Plan") of active participants of such plans who become employees of Newco
  as of the Effective Time or within 90 days thereafter and former
  participants of the PAS Savings Plan, including without limitation retired
  participants and former participants entitled to deferred vested benefits
  and beneficiaries thereof under the PAS Savings Plan ("Transferred Savings
  Plan Participants"), shall, unless otherwise agreed to by PAS and HE, be
  transferred to a new trust under a separate plan established by Newco for
  the Transferred Savings Plan
 
                                     A-55
<PAGE>
 
  Participants and other Newco employees effective as of the Effective Time,
  either in a direct trust-to-trust transfer or in participant directed
  rollover distributions as hereinafter set forth. Newco shall, with the
  cooperation of HE, use its best efforts to accomplish the transfer of the
  foregoing assets and liabilities.
 
    (ii) Effective as of the Effective Time, Newco shall establish a defined
  contribution pension plan (the "Newco Savings Plan") which shall be
  qualified under Sections 401(a) and (k) of the Code and a trust related
  thereto which shall be exempt from taxation under Section 501(a) of the
  Code. The Newco Savings Plan shall contain provisions comparable to and no
  less favorable in the aggregate than the HE Savings Plan (other than the
  investment in GMH stock and matching contribution features) and, subject to
  applicable law, shall, unless otherwise agreed to by PAS and HE, provide
  for employer matching contributions at a rate of 4% of compensation, which
  may, in the discretion of Newco, be made in common stock of Newco, if the
  stock of Newco is publicly traded. To the extent permitted by applicable
  law, credit for past service with PAS and the Galaxy Business prior to the
  Effective Time shall be given under the Newco Savings Plan for the purposes
  of vesting and eligibility to participate.
 
    (iii) The transfer of assets and liabilities from the HE Savings Plan and
  the PAS Savings Plan to the Newco Savings Plan shall be conditioned upon
  the receipt of requisite governmental approvals. Newco shall submit to the
  Internal Revenue Service a request for a determination letter as to the tax
  qualification and exempt status of the Newco Savings Plan. Upon receipt by
  Newco and HE of a determination letter from the Internal Revenue Service,
  or an opinion of counsel reasonably acceptable to HE and PAS, that the
  Newco Savings Plan is qualified under Section 401(a) and (k) of the Code,
  the assets of the PAS Savings Plan and HE Savings Plan that are
  transferable to the Newco Savings Plan as provided herein shall be so
  transferred, but in no event later than 90 days after receipt by Newco and
  HE of such determination letter, whichever occurs later.
 
    (iv) No assets and liabilities shall be transferred in a direct trust-to-
  trust transfer unless the requirements of Section 414(l) of the Code are
  met with respect to the transfer. After the transfer of assets and
  liabilities, the payment of benefits to the Transferred Savings Plan
  Participants accrued under the HE Savings Plan and PAS Savings Plan shall
  be the sole responsibility of Newco.
 
  (c) Newco Stock Options. Newco shall provide stock options to certain
employees from and after the time that Newco's stock is publicly held. As soon
as practicable after execution of the Merger Agreement, a committee shall be
established which shall be composed of representatives of PAS and HCI (the
"Joint Committee"). The Joint Committee shall make recommendations to the
Board of Directors of Newco with regard to such stock options including, but
not limited to, the following: (i) the form of stock option offered, which may
be incentive stock options, nonqualified stock options, or a combination
thereof; (ii) eligibility requirements to receive such stock options; (iii)
vesting requirements; (iv) term of the stock options; (v) exercise price; and
(vi) the maximum number of shares to be offered through stock options, if
required by law. The Joint Committee shall make such recommendations, and take
all other actions necessary to carry out the requirements of this provision,
by the Effective Time. Any stock options issued by Newco shall be registered
with the applicable governmental agencies and shall comply with all applicable
securities laws. The Board of Directors of Newco shall act upon such
recommendations and, if necessary, obtain stockholder approval for the
issuance of Newco stock pursuant to the options described herein.
 
  (d) Retiree Medical Benefits. As soon as practicable after the Effective
Time, HCI or one of its Affiliates shall pay to all Galaxy Employees who are
being transferred to Newco, who have not retired under a Galaxy retiree
medical plan and who would be entitled to receive medical benefits upon
retirement under a Galaxy ERISA Plan (as defined in Section 6.9(c)(i)) or any
other plan or policy maintained by the Galaxy Business, HCI or one of its
Affiliates, an amount of cash to be determined by HCI, after consultation with
PAS, but in no case shall such cash amount paid to each employee be less than
the cash amount to which the employee is legally entitled, if any.
 
  (e) PAS ERISA Plans and PAS Benefits Arrangements. Prior to the Effective
Time, PAS shall take all actions which are reasonably necessary or appropriate
to correct any material defects with respect to the
 
                                     A-56
<PAGE>
 
compliance of each PAS ERISA Plan and PAS Benefit Arrangement with all Laws,
including any actions which are reasonably necessary or appropriate to qualify
any PAS ERISA Plan that is intended to be tax qualified under Section 401(a)
of the Code.
 
  (f) HCI Indemnification. HCI agrees to indemnify, defend and hold harmless
Newco and each of its Subsidiaries and their respective successor(s)-in-
interest against any losses, claims, damages or liabilities, joint or several,
arising from the Galaxy Business' participation in a controlled group, as
defined in Section 414(b), (c), (m), and (o) of the Code, prior to the
Effective Time except with respect to any losses, claims, damages or
liabilities relating to the Galaxy Employees, who will be employed by Newco as
of the Effective Time, the Galaxy ERISA Plans or the Galaxy Benefit
Arrangements.
 
  (g) PAS Indemnification. PAS agrees to indemnify, defend and hold harmless
Newco and each of its Subsidiaries and their respective successor(s)-in-
interest against any losses, claims, damages or liabilities, joint or several,
arising from PAS' participation in a controlled group as defined in Section
414(b), (c), (m) and (o) of the Code prior to the Effective Time except with
respect to any losses, claims, damages or liabilities relating to PAS'
employees who will be employed by Newco as of the Effective Time, the PAS
ERISA Plans or the PAS Benefit Arrangements.
 
  7.17 Further Action. Each party hereto shall, subject to the fulfillment at
or before the Closing Date of each of the conditions of performance set forth
herein or the waiver thereof, perform such further acts and execute such
documents as may be reasonably required to effect the transactions
contemplated by this Agreement. Without limiting the generality of the
foregoing, if the consummation period for consummating the Asset Contribution,
the Univisa Contribution and the Merger pursuant to consents granted by the
FCC expires prior to the date established for the Closing Date, then each
party will use its commercially reasonable efforts to obtain one or more
extensions of the effectiveness of such consents so as to permit the
consummation of the transactions contemplated by this Agreement in accordance
with this Agreement. Each party hereto also agrees to cooperate with the other
parties hereto in connection with communicating with Government Entities in
connection with obtaining approvals of such entity required to effectuate the
transactions contemplated hereby.
 
  7.18 Documentation of Intercompany Agreements. On or prior to the Closing
Date, each Contributed Entity shall enter into written agreements to document
all previously undocumented arrangements with Affiliates of the Contributed
Entities for material goods or services provided to the Galaxy Business, which
new agreements shall be in form reasonably satisfactory to PAS and in
substance consistent with the description of such arrangements set forth on
Schedule 6.15.
 
  7.19 Listing Application. Following execution of the Agreement, Newco shall
prepare and submit to the New York Stock Exchange or the Nasdaq National
Market a listing application covering the shares of Newco Common Stock
issuable in the Asset Contribution and the Merger, and shall use reasonable
efforts to obtain, prior to the Closing Date, approval for the listing of such
Newco Common Stock, subject to official notice of issuance.
 
  7.20 Leveraged Lease Guarantee. Promptly following the Closing, Newco shall
enter into a customary agreement to pay and indemnify HE for obligations
arising under existing guarantees provided by HE of leveraged leases of
transponders used in the Galaxy Business.
 
  7.21 Disposition of Assets. During the period from the date of this
Agreement and continuing until the Closing Date, HCI shall cause all proceeds
from any source with respect to the disposition (whether voluntary or
involuntary) of any asset or group of assets disposed of in related
transactions valued in excess of $60,000 (other than for satellites under
construction) included in the Galaxy Business (net of (i) all taxes that are
paid prior to the Closing as a result of such disposition if the Contributed
Entity owning such asset or assets was a stand-alone company, (ii) any
liabilities related to such asset or assets to the extent they no longer
remain with the Galaxy Business and were not already netted from the proceeds
of such disposition, and (iii) any and all reasonable transaction expenses
(except normal recurring and operating expenses of the Galaxy Business)
related to such
 
                                     A-57
<PAGE>
 
disposition) to be separately identified and retained within the Closed System
(as defined in Section 7.24) (the "Proceeds").
 
  7.22 Related Agreements. Each of the Parties to this Agreement shall, and
shall cause each of its Subsidiaries to, enter into and take all actions
necessary to consummate the transactions contemplated by each of the Related
Agreements to which it is a party, subject in each case to the terms and
conditions of each such Related Agreement.
 
  7.23 Standstill Restriction. For five years following the Closing, none of
the Hughes Parties or their affiliates shall acquire, or come to hold,
beneficially or otherwise, whether by purchase, exchange or otherwise,
individually or in the aggregate more than eighty-one percent (81%) of the
outstanding equity interests in Newco, except (i) pursuant to a merger which
is approved by the holders of majority of the shares of Newco Common Stock not
owned directly or indirectly by HE or any of its affiliates, (ii) pursuant to
a tender offer recommended by the Disinterested Directors of Newco and second-
step merger which offers the same per share consideration to all holders of
Newco Common Stock and in which more than half the outstanding Newco Common
Stock not owned by HCI and its affiliates at the inception of the transaction
is either tendered or voted in favor of the transaction, and (iii) except
pursuant to such other transaction as shall provide for parity of treatment of
holders of Newco Common Stock and is approved by the holders of a majority of
the shares of Common Stock not owned by HCI and its affiliates and by a
majority of the Disinterested Directors of Newco. As used in this Agreement,
"Disinterested Director" means a director of Newco that is not an existing or
retired employee of Newco or any of its affiliates. As used in this Section
7.23, "affiliate" shall have the meaning set forth in Rule 12b-2 under the
Securities Exchange Act of 1934, as amended.
 
  7.24 Capital Expenditures and the Closed System for Cash
Management. Commencing as of July 1, 1996, HE will cause the Galaxy Business
to operate as a separate stand-alone entity with respect to all aspects of its
cash management including retention of the cash receipts and proceeds from all
sources of the business together with the payment of all necessary operating
expenses of the business (excluding non-cash outlays for expenses such as
depreciation and amortization) and capital outlays (including those expenses
and capital outlays that are directly attributable to the business but which
may, for convenience purposes, be paid by HE and redistributed to the Galaxy
Business). The Galaxy Business will also be responsible for the payment of all
properly allocated costs of the Galaxy Business, including its allocated share
of corporate and sector "General & Administrative" costs consistent with the
past accounting practices of the Galaxy Business. The Galaxy Business will
compute an income tax provision for the taxable earnings of the business in
accordance with GAAP and will provide for the appropriate income taxes of the
business including the determination and recognition of necessary deferred tax
amounts (which deferred tax amounts may not be deducted as cash expenses). The
aforementioned practices will constitute a "Closed System" of cash management.
It is explicitly understood that HCI will be required to use cash proceeds
retained in the business (other than Proceeds which may not be used for such
purpose and which shall be part of the "Galaxy Assets" at the Closing) to fund
additions to its "Capital Expenditures for Satellites Under Construction"
accounts. For purposes of this Agreement, "Capital Expenditures for Satellites
Under Construction" shall include manufacturing, launch and launch insurance,
progress payments and capitalized interest amounts. HCI, with the assistance
of HE, will continue to manage and pursue its capital expenditures program for
the construction and development of satellites during the period from July 1,
1996 through the Closing as it deems necessary in the ordinary course of its
business and consistent with prudent business practices. To the extent that
additions to HCI's "Capital Expenditures for Satellites Under Construction"
accounts as determined on a consistent basis and in accordance with GAAP and
HCI's historical accounting practices and procedures, during the period from
July 1, 1996 through the Closing of the Merger do not equal or exceed $575
million in the aggregate, HE shall be obligated to make up any difference in
cash at the Closing.

                                 Article VIII
 
                                  Conditions
 
  8.1 Conditions to Each Party's Obligation to Effect the Asset Contribution,
the Univisa Contribution and the Merger. The respective obligations of each
party to effect the Asset Contribution, the Univisa Contribution and the
Merger shall be subject to the satisfaction on or prior to the Closing Date
(or, if permissible, waiver by the party for whose benefit such conditions
exist) of the following conditions:
 
    (a) No Order. No Government Entity shall have enacted, issued,
  promulgated, enforced or entered any statute, rule, regulation or order
  (whether temporary, preliminary or permanent) which is in effect and which
  materially restricts, prevents or prohibits consummation of the
  transactions contemplated by this Agreement or any of the Related
  Agreements; provided, however, that the parties shall use their
  commercially reasonable efforts to cause any such decree, judgment,
  injunction or other order to be vacated or lifted.
 
    (b) Stockholder Approval. This Agreement and the transactions
  contemplated hereby shall have been approved in the manner required by
  applicable law or by the applicable regulations of any stock exchange or
  other regulatory body, as the case may be, of the holders of the issued and
  outstanding shares of common stock of PAS.
 
    (c) HSR Act. Any waiting period applicable to the consummation of the
  transactions contemplated hereby under the HSR Act shall have expired or
  been terminated, and no action shall have been instituted by the Department
  of Justice or the Federal Trade Commission challenging or seeking to enjoin
  the consummation of the transactions contemplated hereby, which action
  shall not have been withdrawn by the party instituting such action or
  dismissed or terminated pursuant to a final, non-appealable judgment of a
  United States federal court.
 
    (d) FCC Consents. (i) The FCC shall have granted by Final Order the FCC
  Consent Application, without conditions, qualifications or other
  restrictions that are likely to have a material adverse effect immediately
  after the Closing Date, on Newco or any of its Subsidiaries (other than the
  loss of pending applications at the FCC for Permits), whether imposed by
  the FCC or any other Government Entity; and (ii) except for Permits which
  lapse, expire or are terminated due to ordinary course changes in the
  business of PAS and the Galaxy Business, as the case may be, except as
  otherwise contemplated by this Agreement, each of the PAS Permits and the
  Galaxy Permits issued by the FCC shall be in full force and effect,
  unimpaired by any acts or omissions of Galaxy, PAS or their officers,
  directors, employees or agents. As used in this Agreement, the term "Final
  Order" means an order, action or decision of a Government Entity that has
  not been reversed, stayed or enjoined and as to which the time to appeal,
  petition for certiorari or seek reargument or rehearing or administrative
  reconsideration or review has expired and as to which no appeal,
  reargument, petition for certiorari or rehearing or petition for
  reconsideration or application for review is pending or as to which any
  right to appeal, reargue, petition for certiorari or rehearing or
  reconsideration or review has been waived in writing by each party having
  such a right or, if any appeal, reargument, petition for certiorari or
  rehearing or reconsideration or review thereof has been sought, the order
  or judgment of the court or agency has been affirmed by the highest court
  (or the administrative entity or body) to which the order was appealed or
  from which the argument or rehearing or reconsideration or review was
  sought, or certiorari has been denied, and the time to take any further
  appeal or to seek certiorari or further reargument or rehearing, or
  reconsideration or review, has expired. Notwithstanding the foregoing, HCI
  shall have the unilateral right within 60 days after public notice of such
  order, action or decision by the FCC to elect to waive this condition if
  HCI determines, in its sole discretion, that any pending appeal is not
  likely to have a material adverse effect on Newco and its Subsidiaries,
  taken as a whole, following the Asset Contribution, the Univisa
  Contribution and the Merger; provided that, if HCI fails to waive this
  condition within such 60-day period, then either party shall have the right
  to terminate this Agreement.
 
    (e) Other Satellite Approvals. Each Government Entity other than the FCC
  that has issued to PAS or any of its Subsidiaries (i) any Permit with
  respect to the operation of or transmission to or from a PAS

<PAGE>
 
  Satellite or a ground station that communicates with a PAS Satellite (ii)
  any Permit with respect to the provision of broadcasting or communications
  services shall have, where required by applicable Law, approved the
  transfer of control or assignment, as applicable, of all such Permits as a
  result of the Merger without any material qualifications, restrictions or
  limitations and such approval shall have become a Final Order. Each
  Government Entity that has issued to any of the Contributed Entities (i)
  any Permit with respect to the operation of or transmission to or from a
  Galaxy Satellite or a ground station that communicates with a Galaxy
  Satellite, or (ii) any Permit with respect to the provision of broadcasting
  or communications services shall have, where required by applicable Law,
  approved the transfer of control or assignment, as applicable, of all such
  permits as a result of the Asset Contribution without any material
  qualifications, restrictions or limitations and such approval shall have
  become a Final Order.
 
    (f) Other Approvals. All other approvals or orders by Government Entities
  required to be obtained, and all filings, notices or declarations required
  to be made before any Government Entity (other than the FCC), by any party
  prior to the consummation of the transactions contemplated hereunder shall
  have been obtained from, and made with, all required Government Entities
  except for such authorizations, consents, waivers, orders, approvals,
  filings, notices or declarations, the failure to obtain or make which would
  not be likely to have a material adverse effect at or after the Closing
  Date, on Newco or any of its Subsidiaries.
 
    (g) Registration Statement. The Registration Statement with respect to
  the shares of Newco Common Stock issuable in connection with the Merger
  shall have become effective and shall be effective at the Effective Time,
  and no stop order suspending effectiveness of such Registration Statement
  shall have been issued, no action, suit, proceeding or investigation by the
  SEC to suspend the effectiveness thereof shall have been initiated and be
  continuing, or, to the knowledge of HCI or PAS, threatened, and all
  necessary approvals under state securities laws relating to the issuance or
  trading of the shares of Newco Common Stock to be issued in connection with
  the Merger shall have been received.
 
    (h) Related Agreements. Each of the Related Agreements shall have been
  executed, delivered and, to the extent required to be performed by such
  agreements on or prior to the Closing Date, performed (or capable of being
  performed concurrently with consummation of the transactions contemplated
  hereby) by the parties thereto.
 
    (i) Listing Application. The shares of Newco Common Stock issuable in the
  Merger shall have been approved, upon official notice of issuance, for

  8.2 Additional Conditions to Obligations of PAS. The obligation of PAS to
effect the transactions contemplated hereby is subject to the satisfaction of
the following conditions, any or all of which may be waived in whole or in
part by PAS:
 
    (a) Representations and Warranties. Each of the representations and
  warranties of the Hughes Parties set forth in this Agreement shall be true
  and correct in all material respects (without regard to any materiality
  limitations contained in any such representation or warranty, except that,
  subject to the next sentence below, the representation of HCI set forth in
  the last sentence of Section 6.4 shall be true and correct in all respects)
  as of the date of this Agreement (except to the extent such representations
  and warranties speak as of an earlier date or have been amended pursuant to
  Section 7.15 and, other than with respect to the representation of HCI set
  forth in the last sentence of Section 6.4, except for inaccuracies or
  omissions having or reasonably likely to have, individually or in the
  aggregate, an economic impact or consequence (or diminution in value) on
  the Galaxy Business of less than $50,000,000. A breach of the last sentence
  of Section 6.4 shall not be considered a failure of this condition
  precedent, provided any deficiency is cured by the Closing Date. PAS shall
  have received certificates of each of the Chief Executive Officer and the
  Chief Financial Officer of HCI to that effect.
 
    (b) Performance of Obligations. Each of the Hughes Parties and HE shall
  have performed in all material respects (other than the obligations of the
  Hughes Parties and HE pursuant to Sections 7.21 and 7.24, which shall be
  performed as agreed herein without regard to materiality) all obligations
  required to be performed by it under this Agreement and the Related
  Agreements to which it is a party on or before the
 
                                     A-60
<PAGE>
 
  Closing Date. PAS shall have received certificates of the Chief Executive
  Officer and Chief Financial Officer of HCI to that effect. Notwithstanding
  the foregoing, the obligations of PAS to effect the transactions
  contemplated by this Agreement shall not be relieved by the failure of any
  of the foregoing conditions if such failure is the result, directly or
  indirectly, of any breach by PAS of any of its material obligations under
  this Agreement.
 
    (c) Material Adverse Change. Since the date of this Agreement, there
  shall have been no change, occurrence or circumstance (or series of
  changes, occurrences or circumstances) in the business, operations,
  properties, assets, condition (financial or otherwise) or the results of
  operations or prospects of the assets of the Galaxy Business having or
  reasonably likely to have, individually or in the aggregate, an adverse
  economic impact or consequence (including diminution in value) of more than
  $200,000,000. Notwithstanding the foregoing, for purposes of this Section
  8.2(c) none of the following shall be deemed to be a "change," "occurrence"
  or "circumstance": (i) the loss, denial or dismissal of any pending
  application for a Galaxy Permit that has been filed with the FCC or (ii) a
  loss, to the extent caused by or related to (A) a mere delay in the receipt
  of revenue, as opposed to the cancellation or modification of a contract,
  and the consequent loss of revenue related to such delay or (B) the launch
  or in-orbit failure of any Galaxy Satellite, to the extent such loss is
  covered by insurance.
 
  8.3 Additional Conditions to Obligations of the Hughes Parties. The
obligations of the Hughes Parties to effect the transactions contemplated
hereby are subject to the satisfaction of the following conditions, any or all
of which may be waived in whole or in part by HCI:
 
    (a) Representations and Warranties. Each of the representations and
  warranties of PAS set forth in this Agreement shall be true and correct in
  all material respects (without regard to any materiality limitations
  contained in any such representation or warranty) as of the date of this
  Agreement (except to the extent such representations and warranties speak
  as of an earlier date or have been amended pursuant to Section 7.15),
  except for inaccuracies or omissions having or reasonably likely to have,
  individually or in the aggregate, an economic impact or consequence (or
  diminution in value) on PAS and its Subsidiaries taken as a whole of less
  than $50,000,000. HCI shall have received certificates of the Chief
  Financial Officer and Chief Executive Officer of PAS to that effect.
 
    (b) Performance of Obligations. PAS shall have performed in all material
  respects all obligations required to be performed by it under this
  Agreement and the Related Agreements to which it is a party on or before
  the Closing Date. HCI shall have received certificates of the Chief
  Executive Officer and Chief Financial Officer of PAS to that effect.
  Notwithstanding the foregoing, the obligations of HCI to effect the
  transactions contemplated by this Agreement shall not be relieved by the
  failure of any of the foregoing conditions if such failure is the result,
  directly or indirectly, of any breach by any Hughes Party of any of their
  material obligations under this Agreement.
 
    (c) Material Adverse Change. Since the date of this Agreement, there
  shall have been no change, occurrence or circumstance (or series of
  changes, occurrences or circumstances) in the business, operations,
  properties, assets, condition (financial or otherwise) or the results of
  operations or prospects of the assets of PAS having or reasonably likely to
  have, individually or in the aggregate, an adverse economic impact or
  consequence (including diminution in value) of more than $200,000,000.
  Notwithstanding the foregoing, for purposes of this Section 8.3(c) none of
  the following shall be deemed to be a "change," "occurrence" or
  "circumstance": (i) the loss, denial or dismissal of any pending
  application for a PAS Permit that has been filed with the FCC or (ii) a
  loss, to the extent caused by or related to (A) a mere delay in the receipt
  of revenue, as opposed to the cancellation or modification of a contract,
  and the consequent loss of revenue related to such delay or (B) the launch
  or in-orbit failure of any PAS Satellite, to the extent such loss is
  covered by insurance.
 
    (d) Termination of Options. PAS shall have delivered to HCI written
  evidence of the agreement by each holder of Options to terminate such
  Options on or before the Effective Time.
 
    (e) Termination of DTH Equity Obligations. PAS shall have delivered to
  HCI evidence satisfactory to HCI that PAS will, as of the Closing Date,
  terminate all of its obligations under that certain Memorandum
 
                                     A-61
<PAGE>
 
  of Understanding, dated as of March 27, 1995, between PAS and Televisa, and
  the oral agreement between such parties regarding an equity interest in a
  DTH venture in the Iberian Peninsula.
 
    (f) Resignation of PAS Directors. PAS shall have delivered to HCI a
  letter of resignation from each person that is a director of PAS
  immediately prior to the Closing, which resignation shall be effective as

                                  Article IX
 
                           Termination and Amendment
 
  9.1 Termination. This Agreement may be terminated and the Asset
Contribution, the Univisa Contribution and the Merger may be abandoned at any
time prior to the Closing Date, whether before or after stockholder approval
of the Merger:
 
    (a) by mutual written consent of HCI and PAS or by mutual actions of
  their respective Boards of Directors;
 
    (b) by either PAS or HCI, so long as such party is not in breach of its
  obligations hereunder, if the Asset Contribution, the Univisa Contribution
  and the Merger shall not have been consummated on or before that date which
  is fifteen (15) months from the date of this Agreement; provided, however,
  that the right to terminate this Agreement under this Section 9.1(b) shall
  not be available to HCI or PAS if failure to fulfill any obligation under
  this Agreement by a Hughes Party (in the case of HCI) or PAS (in the case
  of PAS) has been the cause of or resulted in the failure of either the
  Asset Contribution, the Univisa Contribution or the Merger to occur on or
  before such date, but the non-breaching party of the Hughes Parties or PAS
  that desires to proceed with the transactions contemplated hereby shall
  consummate such transactions as promptly as practicable;
 
    (c) by either PAS or HCI upon a breach of any representation, warranty,
  covenant or agreement on the part of PAS (with respect to HCI) or a Hughes
  Party (with respect to PAS) contained in this Agreement; or if any
  representation or warranty of PAS (with respect to HCI) or a Hughes Party
  (with respect to PAS) shall have become inaccurate or incomplete, in any
  case such that the conditions set forth in Sections 8.2 or 8.3, as the case
  may be, would be incapable of being satisfied on the Closing Date;
  provided, that in any case, a willful or reckless breach shall be deemed to
  cause such conditions to be incapable of being satisfied for purposes of
  this Section 9.1;
 
    (d) by either HCI or PAS if any injunction or order of a court or other
  competent authority preventing the consummation of any of the Asset
  Contribution, the Univisa Contribution or the Merger shall have become
  permanent, final and non-appealable;
 
    (e) By either of PAS or HCI, if this Agreement and the Merger shall fail
  to receive the requisite vote for approval and adoption by the stockholders
  of PAS;
 
    (f) By HCI, if (i) the Board of Directors of PAS shall withdraw, modify
  or change its recommendation of this Agreement in a manner adverse to any
  of the Hughes Parties or shall have resolved to do any of the foregoing,
  (ii) the Board of Directors of PAS shall have recommended to the
  stockholders of PAS any Acquisition Proposal or (iii) a tender offer or
  exchange offer for 15% or more of the outstanding shares of PAS Common
  Stock is commenced, and the Board of Directors of PAS recommends that the
  holders of such stock tender their shares in such tender or exchange offer;
  or
 
    (g) By PAS' Board of Directors if, in the exercise of its good faith
  judgment as to fiduciary duties owed to its stockholders imposed by law,
  and, provided that PAS' Board of Directors shall have complied with each of
  the requirements set forth in Section 7.1(e), PAS' Board of Directors
  adopts a Superior Acquisition Proposal.
 
  9.2 Effect of Termination. In the event of termination of this Agreement by
HCI or PAS as provided in Section 9.1, (a) written notice thereof shall
forthwith be given to the other parties specifying the provision hereof
pursuant to which such termination is made and (b) this Agreement shall
forthwith become void and there shall
 
                                     A-62
<PAGE>
 
be no liability or obligation on the part of any party or their respective
Subsidiaries, Affiliates, officers, directors or stockholders except to the
extent that such termination results from the willful or reckless breach by
any party hereto of any of its representations or warranties, or of any of its
covenants or agreements, in each case, as set forth in this Agreement. The
last sentence of Section 7.7(a) and the provisions of Sections 7.8 and 9.3
shall survive any termination of this Agreement, unless otherwise agreed by
HCI and PAS. Moreover, in the event of termination of this Agreement pursuant
to Sections 9.1(c), 9.1(f) or 9.1(g), nothing herein shall prejudice the
ability of the terminating party (with respect to a termination pursuant to
Section 9.1(c)) or HCI (with respect to a termination pursuant to Section
9.1(f) or 9.1(g)) from seeking damages from any other party for any willful
breach of this Agreement, including, without limitation, attorney's fees, and
the right to pursue any remedy at law or in equity.
 
  9.3 Termination Fee. PAS agrees that if this Agreement shall be terminated
pursuant to (i) Section 9.1(b) hereof at any time when (a) an Acquisition
Proposal shall have been made by a third party but shall not have been
rejected by PAS and (b) PAS or any of its Subsidiaries or PAS' stockholders
shall thereafter consummate or agree to consummate a transaction which would
constitute an Acquisition Proposal with any person within twelve (12) months
from the date of such termination, (ii) Section 9.1(e) (with respect to the
failure to obtain the requisite vote by the stockholders of PAS) and there
shall have been made and not withdrawn or rejected an Acquisition Proposal,
(iii) Section 9.1(f), or (iv) Section 9.1(g), then in any such event PAS shall
pay to HCI an amount equal to $80,000,000 (the "Termination Fee"), payable (x)
in the case of termination under clause (i) above upon signing of a definitive
agreement relating to such Acquisition Proposal referred to in clause (i) of
this Section 9.3, or, if no such agreement is executed, then at the closing
(and as a condition to the Closing) of such Acquisition Proposal, and (y)
within one business day of termination of this Agreement upon any termination
of this Agreement described in clauses (ii), (iii), or (iv) above. In any case
in which a Termination Fee is payable by PAS under this Section 9.3, PAS also
shall assume and pay or reimburse HCI for all reasonable fees and expenses
incurred by HCI and its Affiliates (including the fees and expenses of their
counsel, accountants, financial advisors and funding sources) which are
specifically related to the matters contemplated by this Agreement and the
Related Agreements, but not to exceed $7,500,000 in the aggregate, payable
concurrently with the payment of the Termination Fee. PAS acknowledges that
the agreements contained in this Section 9.3 hereof are an integral part of
the transactions contemplated by this Agreement. Accordingly, if PAS shall
fail to pay when due any amounts which shall become due under Section 9.3
hereof, PAS shall in addition hereto pay to HCI all costs and expenses
(including fees and disbursements of counsel) incurred in collecting such
overdue amounts, together with interest on such overdue amounts from the date
such payment was required to be made until the date such payment is received
at a rate per annum equal to the "reference rate" as announced from time to
time by Bank of America NT&SA. Any payment required to be made pursuant to
Section 9.3 shall be made when due by wire transfer of immediately available
funds to an account designed by HCI.
 
  9.4 Amendment.
 
  (a) Subject to applicable law, this Agreement may be amended, modified or
supplemented only by written agreement of the parties at any time prior to the
Effective Date with respect to any of the terms contained herein; provided,
however, that, after this Agreement is adopted by PAS' stockholders, no such
amendment or modification shall reduce the amount or change the form of
consideration to be delivered to the holders of Shares or adversely affect the
rights of such holders of Shares without the consent of PAS' stockholders duly
obtained. In addition, HCI agrees not to amend, modify or terminate any of the
Univisa Contribution Agreement, the Collateral Trust Agreement or the Pledge
and Security Agreement without the prior written approval of PAS.
 
  (b) In the enforcement, interpretation or amendment of any provisions herein
or under the Related Agreements by Newco affecting the rights and obligations
of HE or its Affiliates following the Closing, Newco shall be represented by a
committee of the Board of Directors of Newco comprised solely of Disinterested
Directors.
 
  9.5 Extension; Waiver. At any time prior to the Effective Time, and subject
to applicable law, the parties hereto, by action taken or authorized by their
respective Boards of Directors, may, to the extent legally allowed:
 
                                     A-63
<PAGE>
 
(i) extend the time for the performance of any of the obligations or other
acts of the other parties hereto; (ii) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto; and (iii) waive compliance with any of the agreements or
conditions contained herein. Any agreement on the part of a party hereto to
any such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party. The failure of any party hereto to
assert any of its rights hereunder shall not constitute a waiver of such
rights.
 
                                   Article X
 
                              General Provisions
 
  10.1 Nonsurvival of Representations, Warranties and Agreements. None of the
representations, warranties, covenants and agreements in this Agreement or in
any instrument delivered pursuant to this Agreement shall survive the
Effective Time, except for the agreements contained in Sections 7.10 and 7.11
hereof and for those other covenants and agreements specifically requiring
performance following the Closing. The Confidentiality Agreement shall survive
the execution and delivery of this Agreement, and the provisions of the
Confidentiality Agreement shall apply to all information and material
delivered by any party hereunder.
 
  10.2 Expenses. Whether or not the Asset Contribution, the Univisa
Contribution and the Merger are consummated, all costs and expenses incurred
in connection with this Agreement and the transactions contemplated hereby
shall be paid by the party incurring such expenses except as expressly
provided herein and except that (a) the filing fees in connection with the HSR
Act filing, (b) the filing fees in connection with the filing of the Proxy
Statement/Prospectus and the Registration Statements with the SEC, (c) the
filing fees in connection with necessary applications to the FCC and similar
foreign agencies, (d) the expenses incurred in connection with printing and
mailing the Registration Statement and the Proxy Statement/Prospectus and (e)
fees and expenses related to any expert consultants (excluding attorneys and
accountants) retained in connection with or related to any of the applications
or filings otherwise contemplated by this Section 10.2, shall be shared
equally by the Hughes Parties, on the one hand, and PAS, on the other hand.

  10.4 Interpretation. When a reference is made in this Agreement to Sections,
such reference shall be to a Section of this Agreement unless otherwise
indicated. The table of contents and headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. Whenever the word "include", "includes" or
"including" are used in this Agreement, they shall be deemed to be followed by
the words "without limitation." The phrase "made available" in this Agreement
shall mean that the information referred to has been made available if
requested by the party to whom such information is to be made available. This
Agreement shall not be construed for or against either party by reason of the
authorship or alleged authorship of any provision hereof or by reason of the
status of the respective parties.
 
  10.5 Entire Agreement; No Third-Party Beneficiaries; Rights of
Ownership. This Agreement (together with the Related Agreements and any other
documents and instruments referred to herein, including exhibits and
schedules) constitutes the entire agreement and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof and, except as provided in Section 7.10
(which is intended to be for the benefit of the persons referred to therein
and their beneficiaries, and may be enforced by them as third-party
beneficiaries), is not intended to confer upon any person other than the
parties hereto any rights or remedies hereunder.
 
  10.6 Assignment. Neither this Agreement nor any of the rights, interests,
obligations hereunder shall be assigned by either of the parties hereto
(whether by operation of law or otherwise) without the prior written consent
of the other party. Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of and be enforceable by the parties and
their respective successors and assigns.
 
  10.7 Governing Law. This Agreement shall be construed, interpreted and the
rights of the parties determined in accordance with the laws of the State of
Delaware (without reference to the choice of law provisions), except with
respect to matters of law concerning the internal corporate affairs of any
corporate entity which is a party to or the subject of this Agreement, and as
to those matters the law of the jurisdiction under which the respective entity
derives its powers shall govern.
 
 
                                     A-65

  10.8 Severability. Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part hereof to be
null, void or unenforceable, or order any party to take any action
inconsistent herewith or not to take an action consistent herewith or required
hereby, the validity, legality and enforceability of the remaining provisions
and obligations contained or set forth herein shall not in any way be affected
or impaired thereby, unless the foregoing inconsistent action or the failure
to take an action constitutes a material breach of this Agreement or makes the
Agreement impossible to perform, in which case this Agreement shall terminate
pursuant to Article IX hereof. Upon any such holding that any provision of
this Agreement is null, void or unenforceable, the parties will negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that the
transactions contemplated by this Agreement are consummated to the extent
possible. Except as otherwise contemplated by this Agreement, to the extent
that a party hereto took an action inconsistent herewith or failed to take
action consistent herewith or required hereby pursuant to an order or judgment
of a court or other competent authority, such party shall incur no liability
or obligation unless such party did not in good faith seek to resist or object
to the imposition or entering of such order or judgment.
 
  10.9 Injunctive Relief. The parties acknowledge that it will be impossible
to measure in money the damages that would be suffered if the parties fail to
comply with any of the obligations herein imposed on them and that in the
event of any such failure, an aggrieved person or entity will be irreparably
damaged and will not have an adequate remedy at law. Any such person or entity
shall, therefore, be entitled to injunctive relief, including specific
performance, to enforce such obligations, and if any action should be brought
in equity to enforce any of the provisions of this Agreement, none of the
parties shall raise the defense that there is an adequate remedy at law.
 
  10.10 Attorneys' Fees. If any party to this Agreement brings an action to
enforce its rights under this Agreement, the prevailing party shall be
entitled to recover its costs and expenses, including without limitation
reasonable attorneys' fees, incurred in connection with such action, including
any appeal of such action.
 
  10.11 Cumulative Remedies. All rights and remedies of either party hereto
are cumulative of each other and of every other right or remedy such party may
otherwise have at law or in equity, and the exercise of one or more rights or
remedies shall not prejudice or impair the concurrent or subsequent exercise
of other rights or remedies.
 
  10.12 Counterparts. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same instrument and
shall become effective when executed and delivered by each of the parties.

                                   RECITALS
 
  A. The parties hereto have entered into the Agreement and Plan of
Reorganization ("Reorganization Agreement") dated as of September 20, 1996,
which provides for the combination of PAS with the Galaxy Business. All terms
used herein that are not otherwise defined herein shall have the meaning
ascribed to them in the Reorganization Agreement.
 
  B. The Reorganization Agreement contemplates that on or prior to the Closing
Date certain parties will enter into the Registration Rights Agreement and the
Stockholder Agreement, in the forms attached as Exhibits F and G,
respectively, to the Reorganization Agreement.
 
  C. The parties desire to make certain revisions to the Reorganization
Agreement, Registration Rights Agreement and the Stockholder Agreement.
 
  In consideration of the foregoing and the mutual promises herein and for
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto, intending to be legally bound, hereby
agree as follows:
 
                                   ARTICLE I
 
                                   AMENDMENT
 
  1.1. Recital G is hereby amended to delete the words "a Registration Rights
Agreement" where such words occur on the third line thereof and to insert in
their place the words "an amended and restated registration rights agreement."
 
  1.2. Exhibit F to the Reorganization Agreement is hereby amended (i) to
rename such agreement the "Amended and Restated Registration Rights Agreement"
in the title, in the heading and in the last sentence of such agreement and
(ii) to delete the definition of "Class A Holder" and insert the following in
its place:
 
  "Class A Holder" means a Holder whose Common Stock was received in the
  Transactions in respect of the Class A Common Stock or common stock of
  PanAmSat Corporation into which such Class A Common Stock has been
  converted."
 
  1.3. Recital H is hereby amended to delete the words "a stockholder
agreement" where such words occur on the third line thereof and to insert in
their place the words "an amended and restated stockholder agreement."
 
  1.4. Exhibit G to the Reorganization Agreement is hereby amended (i) to
rename such agreement the "Amended and Restated Stockholder Agreement" in the
title, in the heading and in the last sentence of such agreement, (ii) to
delete the amount "$1.5 billion," as such amount appears in subpart (y) to the
proviso of Section 2(b) thereof and to insert in its place the amount "$1.725
billion" and (iii) to add the following sentence at the end of Section 3(a):
"Any vacancy of an available A Group or B Group director position will be
filled
 
                                     AA-1
<PAGE>
 
promptly without holding a meeting of stockholders of the Company at the
request of the A Group or B Group, as applicable, with their designee;
provided that the A Group or B Group, as applicable, shall beneficially own a
number of shares greater than the Director Minimum Shares at the time of
filling such vacancy."
 
  1.5. Pursuant to Section 4.3(g) of the Reorganization Agreement, the parties
may require that holders making elections as to the Merger Consideration
respond prior to the Merger, upon such additional terms and conditions as may
be agreed to by the parties. The parties have agreed that the Election Forms
shall be submitted to the Exchange Agent by holders of record of the Shares on
the Record Date (as defined below) by 5:00 p.m. (Eastern Standard Time) on May
2, 1997; provided however, that if the date of the special meeting of
stockholders of PAS held to approve the Merger (the "Special Meeting") is
postponed or adjourned, then the Election Forms shall be submitted to the
Exchange Agent by 5 p.m. (Eastern Standard Time) on the day immediately
preceding the date of the Special Meeting and hereby agree that, in order to
effect such result, the Exchange Agent shall mail the Letter of Transmittal to
each holder of record of Shares on the record date for the Special Meeting
(the "Record Date") simultaneously with the mailing of the proxy with respect
to such meeting (not as soon as reasonably practicable after the Effective
Time, as currently provided in Section 4.3(c)), with instructions to return
the Election Form to the Exchange Agent by 5:00 p.m. (Eastern Standard Time)
on May 2, 1997; provided however, that if the date of the Special Meeting is
postponed or adjourned, then the Election Forms shall be submitted to the
Exchange Agent before 5 p.m. (Eastern Standard Time) on the day immediately
preceding the date of the Special Meeting (such time and date shall be the
"Election Deadline"). Holders of Shares that have been transferred following
the Record Date or that fail to make an effective election will be deemed to
have made a Standard Election with respect to such Shares.
 
  1.6. Subsection (iii) of Section 4.6 of the Reorganization Agreement is
hereby deleted and the following inserted in its place:
 
  "(iii) the aggregate amount of cash, and shares of Newco Common Stock, if
  any, received by holders on account of Shares for which Cash Elections or
  Stock Elections had been made shall be adjusted in accordance with Section
  4.4 first to distribute the additional cash made available because of the
  adjustment described in subsection (ii) above with respect to Shares for
  which a Cash Election had been made but for which sufficient cash was not
  available and second to distribute the additional shares of Newco Common
  Stock made available because of such reallocation of cash with respect to
  Shares for which Stock Elections had been made but for which sufficient
  shares of Newco Common Stock were not available."
 
  1.7. Section 5.2, sentence 6 of the Reorganization Agreement is hereby
amended to insert after the words "Stock Option Plans" the following words
"and from the conversion of 19,228,017 shares of Class A Common Stock into
19,228,017 shares of PAS Common Stock."
 
  1.8. In accordance with Section 7.1 of the Reorganization Agreement, and
notwithstanding Section 7.1(b), (c) and (d) of the Reorganization Agreement
and anything to the contrary in the Principal Stockholders Agreement, the
parties hereto hereby consent to (i) the conversion of 19,228,017 shares of
PAS Class A Common Stock and the issuance by PAS of 19,228,017 shares of PAS
Common Stock therefor and (ii) the amendments to the Certificate of
Incorporation and Bylaws of PAS attached as exhibits to the Proxy
Statement/Prospectus confidentially submitted to the Securities and Exchange
Commission on March 18, 1997, as the same may be amended prior to filing of
the Proxy Statement/Prospectus with the Securities and Exchange Commission.
 
                                  ARTICLE II
 
                              GENERAL PROVISIONS

be merged with and into PAS (the "Merger") and the separate corporate

franchises of a public as well as of a private nature and be subject to all
the restrictions, disabilities, and duties of each of PAS and Merger Sub; and
all and singular rights, privileges, powers and franchises of each of PAS and
Merger Sub, and all property, real, personal and mixed, and all debts due to
each of PAS and Merger Sub on whatever account, as well as for stock
subscriptions and all other things in action or belonging to each of PAS and
Merger Sub, shall be vested in the Surviving Corporation; and all property,
rights, privileges, powers and franchises, and all and every other interest
shall be thereafter as effectually the property of the Surviving Corporation
as they were of PAS and Merger Sub, and the title to any real estate vested by
deed or otherwise, in each of PAS and Merger Sub shall not revert or be in any
way impaired; but all rights of creditors and all liens upon any property of
either PAS or Merger Sub shall thenceforth attach to the Surviving
Corporation, and may be enforced against it to the same extent as if said
debts and liabilities had been incurred by it.

  SECTION 1.2. Certificate of Incorporation and Bylaws. The Certificate of
Incorporation and Bylaws of PAS in effect at the Effective Time shall be the
Certificate of Incorporation and Bylaws of the Surviving Corporation until

the Certificate of Incorporation of PAS shall be amended, effective prior to
the Univisa Contribution, as set forth on Exhibit A.
 
  SECTION 1.3. Directors. The directors of Merger Sub immediately prior to the
Effective Time shall resign as directors of Merger Sub and be the directors of
the Surviving Corporation as of the Effective Time and until their successors
are duly appointed or elected in accordance with applicable law.

writing by the parties hereto and the parties to the Reorganization Agreement
and the Univisa Contribution Agreement (the "Closing"). The Merger shall
become effective at the time and date which is (i) the later of the date and
time of the filing of the certificate of merger relating to the Merger with

                                  ARTICLE II
 
                             CONVERSION OF SHARES
 
  SECTION 2.1. Merger Sub Common Stock. At the Effective Time, the shares of
Merger Sub Common Stock outstanding immediately prior to the Effective Time
shall be converted into and shall become (i) the number of shares of Class A
Common Stock of the Surviving Corporation that is equal to the number of
shares of, and having terms identical in all respects to, the Class A Common
Stock outstanding immediately prior to the Merger and (ii) the number of
shares of Common Stock of the Surviving Corporation that is equal to the
number of shares of, and having terms identical in all respects to, PAS Common
Stock outstanding immediately prior to the Merger.
 
  SECTION 2.2. Conversion of PAS Shares. (a) Except as otherwise provided in
Section 2.4 and subject to Sections 2.2(c) and 2.2(d) hereof, at the Effective
Time, each issued and outstanding share, other than, to the fullest extent
permitted by law, any share owned by Newco or any wholly-owned Subsidiary of
Newco, of PAS Common Stock and Class A Common Stock (collectively, the
"Shares") shall be converted into, at the election of the holder thereof, one
of the following (as may be adjusted pursuant to Sections 2.4 and 2.6, the
"Merger Consideration"):
 
    (i) for each such Share with respect to which an election to receive a
  combination of Newco Common Stock and cash has been effectively made and
  not revoked or lost pursuant to Sections 2.3(c), (d) and (e) (a "Standard
  Election"), the right to receive (x) an amount in cash equal to one-half of
  the Standard Cash Consideration plus (y) one-half (0.5) share of Newco
  Common Stock (collectively, the "Standard Consideration"). The "Standard
  Cash Consideration" means an amount in cash equal to thirty dollars
  ($30.00), provided that, if the Closing shall not have occurred on or prior
  to the first anniversary of this Agreement, the Standard Cash Consideration
  shall be increased at a rate equal to 9% per annum from and including the
  first anniversary date to but excluding the Closing Date; or
 
    (ii) for each such Share with respect to which an election to receive
  solely Newco Common Stock has been effectively made and not revoked or lost
  pursuant to Sections 2.3(c), (d) and (e) (a "Stock Election"), the right to
  receive one (1) share of Newco Common Stock (the "Stock Consideration"); or
 
 
                                      B-2
<PAGE>
 
    (iii) for each such Share with respect to which an election to receive
  solely cash has been effectively made and not revoked or lost pursuant to
  Sections 2.3(c), (d) and (e) (a "Cash Election"), the right to receive the
  Standard Cash Consideration.
 
  (b) As a result of the Merger and without any action on the part of the
holder thereof, at the Effective Time, (i) all Shares shall cease to be
outstanding and shall be cancelled and retired and shall cease to exist, and
each such holder of Shares shall thereafter cease to have any rights with
respect to such Shares, except the right to receive, without interest, the
Merger Consideration and cash in lieu of fractional shares of Newco Common
Stock in accordance with Section 2.5(c) hereof upon the surrender of a
certificate representing such Shares (a "Share Certificate") except that
Shares, if any, held by Newco (or any wholly-owned Subsidiary of Newco) shall
continue to be outstanding to the fullest extent permitted by law and (ii) all
outstanding shares of Class B Common Stock and the Preferred Stock shall not
be converted in the Merger and shall continue to be outstanding.
 
  (c) Notwithstanding anything contained in this Section 2.2 to the contrary,
each Share issued and held in PAS' treasury immediately prior to the Effective
Time shall, by virtue of the Merger, cease to be outstanding and shall be
cancelled and retired without payment of any consideration therefor.
 
  (d) Notwithstanding anything in this Section 2.2 to the contrary, Shares
which are issued and outstanding immediately prior to the Effective Time and
which are held of record by stockholders who have not voted such shares in
favor of the Merger and who shall have properly exercised their rights of
appraisal for such shares in the manner provided by the DGCL (the "Dissenting
Shares") shall be deemed to have made a Cash Election for purposes of Section
2.4 hereof, and shall not be converted into the right to receive the Merger
Consideration, unless and until such holder shall have failed to perfect or
shall have effectively withdrawn or lost its right to appraisal and payment,
as the case may be. If such holder shall have so failed to perfect its
appraisal right or shall have effectively withdrawn or lost such right, its
shares shall thereupon be deemed to have been converted into and to have
become exchangeable for, at the Effective Time, the right to receive the
Standard Consideration, without any interest thereon. PAS shall give Newco
prompt notice of any Dissenting Shares (and shall also give Newco prompt
notice of any withdrawals of such demands for appraisal rights) and Newco
shall have the right to direct all negotiations and proceedings with respect
to any such demands. Neither PAS nor the Surviving Corporation surviving the
Merger shall, except with the prior written consent of Newco, voluntarily make
any payment with respect to, or settle or offer to settle, any such demand for
appraisal rights.
 
  (e) At the Effective Time, each holder of a then-outstanding option to
purchase Shares under PAS' Long-Term Stock Investment Plan and the Option
Agreements between PAS and certain of its executive officers and other
employees (collectively, the "Stock Option Plans"), whether or not then
exercisable (the "Options"), shall, in settlement thereof, receive for each
Share subject to such Option an amount (subject to any applicable withholding
tax) in cash equal to the difference between (i) the Standard Cash
Consideration and (ii) the per Share exercise price of such Option to the
extent such difference is a positive number (such amount being hereinafter
referred to as the "Option Consideration"); provided, however, that with
respect to any person subject to Section 16(b) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), any such amount shall be paid as
soon as practicable after the first date payment can be made without liability
to such person under Section 16(b) of the Exchange Act. Upon receipt of the
Option Consideration, the Option shall be canceled. The surrender of an Option
to the Surviving Corporation in exchange for the Option Consideration shall be
deemed a release of any and all rights the holder had or may have had in
respect of such Option. Prior to the Effective Time, PAS shall obtain all
necessary consents or releases from holders of Options under the Stock Option
Plans and take all such other lawful action as may be necessary to give effect
to the transactions contemplated by this Section 2.2(e) (except for any such
action that may require the approval of PAS' stockholders). Except as
otherwise agreed to by the parties, (i) the Stock Option Plans shall terminate
as of the Effective Time and the provisions in any other plan, program or
arrangement providing for the issuance or grant of any other interest in
respect of the capital stock of PAS or any Subsidiary thereof, shall be
canceled as of the Effective Time, and (ii) PAS shall assure that following
the Effective Time no participant in the Stock Option Plans or other plans,
programs or arrangements shall have any right thereunder to acquire equity
securities of the Surviving Corporation, the corporation surviving the Merger
or any Subsidiary thereof and to terminate all such plans at the Effective
Time.

 SECTION 2.3. Elections by Holders of Shares.
 
  (a) Each person who, at the Effective Time, is a record holder of Shares
(other than holders of Shares to be cancelled as set forth in Section 2.2(c)
or Dissenting Shares) shall have the right to submit an Election Form (as
defined in Section 2.3(c)) specifying the number of Shares that such person
desires to have converted into the right to receive Newco Common Stock and
cash pursuant to the Standard Election, the number of Shares that such person
desires to have converted into the right to receive Newco Common Stock
pursuant to a Stock Election and the number of Shares that such person desires
to have converted into the right to receive cash pursuant to a Cash Election.
 
  (b) Promptly after the Allocation Determination (as defined in Section
2.3(d)), Newco shall deposit (or cause to be deposited) with a bank or trust
company to be designated by HCI and reasonably acceptable to PAS (the
"Exchange Agent"), for the benefit of the holders of Shares and S Company, for
exchange in accordance with this Article II and the Univisa Contribution
Agreement, (i) cash in the amount sufficient to pay the aggregate cash portion
of the Merger Consideration and the consideration payable in the Univisa
Contribution and (ii) certificates representing the shares of Newco Common
Stock ("Newco Certificates") for exchange in accordance with this Article II
and the Univisa Contribution Agreement (the cash and shares deposited pursuant
to clauses (i) and (ii) being hereinafter referred to as the "Exchange Fund").
Newco Common Stock into which Shares shall be converted pursuant to the Merger
shall be deemed to have been issued at the Effective Time.
 
  (c) As soon as reasonably practicable after the Effective Time, the Exchange
Agent shall mail to each holder of record of Shares immediately prior to the
Effective Time (excluding any Shares which will be cancelled pursuant to
Section 2.2(c) or Dissenting Shares) (A) a letter of transmittal (the "Letter
of Transmittal") (which shall specify that delivery shall be effected, and
risk of loss and title to Share Certificates shall pass, only upon delivery of
such Share Certificates to the Exchange Agent and shall be in such form and
have such other provisions as Newco shall specify), (B) instructions for use
in effecting the surrender of Share Certificates in exchange for the Merger
Consideration with respect to the Shares formerly represented thereby and (C)
an election form (the "Election Form") providing for such holders to make the
Standard Election, the Stock Election or the Cash Election. As of the Election
Deadline (as defined in Section 2.3(d)), all holders of Shares immediately
prior to the Effective Time that shall not have submitted to the Exchange
Agent or shall have properly revoked an effective, properly completed Election
Form shall be deemed to have made a Standard Election.
 
  (d) Any Standard Election, Stock Election or Cash Election shall have been
validly made only if the Exchange Agent shall have received by 5:00 p.m. New
York time on a date (the "Election Deadline") to be mutually agreed upon by
HCI, Newco and PAS, an Election Form properly completed and executed (with the
signature or signatures thereof guaranteed to the extent required by the
Election Form) by such holder accompanied by such holder's Share Certificates,
or by an appropriate guarantee of delivery of such Share Certificates from a
member of any registered national securities exchange or of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company
in the United States as set forth in such Election Form. Any holder of Shares
who has made an election by submitting an Election Form to the Exchange Agent
may, at any time prior to the Election Deadline, change such holder's election
by submitting a revised Election Form, properly completed and signed that is
received by the Exchange Agent prior to the Election Deadline. Any holder of
PAS Common Stock may at any time prior to the Election Deadline revoke his
election and withdraw his Share Certificates deposited with the Exchange Agent
by written notice to the Exchange Agent received by the close of business on
the day prior to the Election Deadline. As soon as practicable after the
Election Deadline, the Exchange Agent shall determine the allocation of the
cash portion of the Merger Consideration and the stock portion of the Merger
Consideration and shall notify Newco of its determination (the "Allocation
Determination").
 
  (e) Upon surrender of a Share Certificate for cancellation to the Exchange
Agent, together with the Letter of Transmittal duly executed, and such other
documents as Newco or the Exchange Agent shall reasonably request, the holder
of such Share Certificate shall be entitled to receive promptly after the
Allocation

Determination in exchange therefor (A) a certified or bank cashier's check in
the amount equal to the cash, if any, which such holder has the right to
receive pursuant to the provisions of this Article II (including any cash in
lieu of fractional shares of Newco Common Stock pursuant to Section 2.5(c)),
and (B) a Newco Certificate representing that number of shares of Newco Common
Stock, if any, which such holder has the right to receive pursuant to this
Article II (in each case less the amount of any required withholding taxes),
and the Share Certificate so surrendered shall forthwith be cancelled. Until
surrendered as contemplated by this Section 2.3(e), each Share Certificate
shall be deemed at any time after the Effective Time to represent only the
right to receive the Merger Consideration with respect to the Shares formerly
represented thereby.
 
  (f) Newco shall have the right to make reasonable rules, not inconsistent
with the terms of this Merger Agreement, governing the validity of the
Election Forms, the manner and extent to which Standard Elections, Stock
Elections or Cash Elections are to be taken into account in making the
determinations prescribed by Section 2.4, the issuance and delivery of
certificates for Newco Common Stock into which Shares are converted in the
Merger, and the payment of cash for Shares converted into the right to receive
cash in the Merger.
 
  (g) Notwithstanding the foregoing provisions of this Section 2.3, the
parties hereto may decide to distribute Election Forms to PAS' stockholders
and require that holders making such elections respond prior to the Merger,
upon such additional terms and conditions as may be agreed to by the parties.
 
 SECTION 2.4. Proration.
 
  (a) As is more fully set forth below and except as may be paid pursuant to
Section 2.5 or otherwise in respect of Dissenting Shares, the aggregate amount
of cash to be paid in the Merger and in the Univisa Contribution Agreement
(other than the cash payment of $225 million provided for in the last sentence
of Section 1.2(a) of the Univisa Contribution Agreement) shall not exceed the
product of (x) one-half ( 1/2) of the Standard Cash Consideration and (y) the
aggregate number of shares of PAS Common Stock, Class A Common Stock and Class
B Common Stock issued and outstanding immediately prior to the Effective Time
(such product, the "Maximum Cash Amount").
 
  (b) In the event that the sum of the aggregate amount of cash represented by
the Cash Elections hereunder (including Cash Elections deemed to have been
made with respect to Dissenting Shares) and under the Stock Contribution and
Exchange Agreement dated as of September 20, 1996 (the "Univisa Contribution
Agreement") received by the Exchange Agent (such sum, the "Requested Cash
Amount") exceeds the Maximum Cash Amount minus the aggregate amount of cash
payable on account of all Standard Elections made or deemed to have been made
hereunder or under the Univisa Contribution Agreement (such difference, the
"Cash Cap"), each holder making a Cash Election hereunder or under the Univisa
Contribution Agreement shall receive, for each Share or Value Unit (as defined
in the Univisa Contribution Agreement), as the case may be, with respect to
which a Cash Election has been made hereunder or under the Univisa
Contribution Agreement, (x) cash in an amount equal to the Prorated Cash
Amount and (y) a number of shares of Newco Common Stock equal to a fraction,
the numerator of which is equal to the Standard Cash Consideration minus the
Prorated Cash Amount and the denominator of which is the Standard Cash
Consideration. The term "Prorated Cash Amount" means the greater of (i) one-
half ( 1/2) of the Standard Cash Consideration and (ii) the product of the
Standard Cash Consideration and a fraction, the numerator of which is the Cash
Cap and the denominator of which is the Requested Cash Amount.
 
  (c) The aggregate number of shares of Newco Common Stock that may be issued
pursuant to Stock Elections hereunder and under the Univisa Contribution
Agreement is not subject to any maximum. In the event that the Requested Cash
Amount is less than the Cash Cap, each holder making a Stock Election
hereunder or under the Univisa Contribution Agreement shall receive, at the
option of Newco, for each Share or Value Unit, as the case may be, with
respect to which a Stock Election has been made hereunder or under the Univisa
Contribution Agreement, (x) not more than the Stock Consideration and not less
than a number of shares of Newco Common Stock equal to a fraction the
numerator of which is the Requested Stock Amount minus the difference between
the Cash Cap and the Requested Cash Amount, and the denominator of which is
the
 
                                      B-5
<PAGE>
 
Requested Stock Amount (such whole or fractional share, the "Prorated Stock
Amount") and (y) cash in an amount equal to the product of (A) the Standard
Cash Consideration and (B) one minus the Prorated Stock Amount. The term
"Requested Stock Amount" means the product of the aggregate number of shares
of Newco Common Stock represented by Stock Elections hereunder or under the
Univisa Contribution Agreement received by the Exchange Agent and the Standard
Cash Consideration.
 
 SECTION 2.5. Dividends, Fractional Shares, Etc.
 
  (a) Notwithstanding any other provisions of this Agreement, no dividends or
other distributions declared after the Effective Time on Newco Common Stock
shall be paid with respect to any Shares which, prior to the Effective Time,
were represented by a Share Certificate until such Share Certificate is
surrendered for exchange as provided herein. Subject to the effect of
applicable Laws, following surrender of any such Share Certificate, there
shall be paid to the holder of the Newco Certificates issued in exchange
therefor, without interest, (i) at the time of such surrender, the amount of
dividends or other distributions with a record date after the Effective Time
theretofore payable with respect to such whole shares of Newco Common Stock
and not paid, less the amount of any withholding taxes which may be required
thereon, and (ii) at the appropriate payment date, the amount of dividends or
other distributions with a record date after the Effective Time but prior to
surrender and a payment date subsequent to surrender payable with respect to
such whole shares of Newco Common Stock, less the amount of any withholding
taxes which may be required thereon.
 
  (b) At or after the Effective Time, there shall be no transfers on the stock
transfer books of the Surviving Corporation of the Share Certificates which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, certificates formerly representing any such Shares are
presented to the Surviving Corporation, they shall be cancelled and exchanged
for certificates for the consideration, if any, deliverable in respect thereof
pursuant to this Merger Agreement in accordance with the procedures set forth
in this Article II. Share Certificates surrendered for exchange by any person
constituting an "affiliate" of PAS for purposes of Rule 145(c) under the
Securities Act of 1933, as amended, shall not be exchanged until Newco has
received a written agreement from such person as provided in Section 7.14 of
the Reorganization Agreement.
 
  (c) No fractional shares of Newco Common Stock shall be issued pursuant to
the Merger or the Univisa Contribution. In lieu of the issuance of any
fractional share of Newco Common Stock pursuant to the Merger or the Univisa
Contribution, cash adjustments will be paid to holders in respect of any
fractional share of Newco Common Stock that would otherwise be issuable, and
the amount of such cash adjustment shall be equal to the product of such
fractional amount and the Standard Cash Consideration.
 
  (d) Any portion of the Exchange Fund (including the proceeds of any
investments thereof and any shares of Newco Common Stock) that remains
unclaimed by the former stockholders of PAS six months after the Effective
Time shall be delivered to Newco. Any former stockholder of PAS who has not
theretofore complied with this Article II shall thereafter look only to Newco
for payment of the consideration payable on account of the Univisa
Contribution or the Merger, as the case may be, cash in lieu of fractional
shares and unpaid dividends and distributions on the Newco Common Stock
deliverable in respect of each share such stockholder holds as determined
pursuant to this Agreement, in each case without any interest thereon.
 
  (e) None of HCI, its Affiliates, PAS, Newco, the Exchange Agent or any other
person shall be liable to any former holder of Shares or shares of Class B
Common Stock for any amount properly delivered to a public official pursuant
to applicable abandoned property, escheat or similar laws.
 
  (f) In the event that any Share Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Share Certificate to be lost, stolen or destroyed and, if required by
Newco, the posting by such person of a bond in such reasonable amount as Newco
may direct as indemnity against any claim that may be made against it with
respect to such Share Certificate, the Exchange Agent will issue in exchange
for such lost, stolen or destroyed Share Certificate the applicable Merger
Consideration, cash in lieu of fractional shares, and unpaid dividends and
distributions on Shares as provided in this Section 2.5, deliverable in
respect thereof pursuant to this Merger Agreement.

  SECTION 2.6. Certain Additional Prorations. In the event that the aggregate
number of shares of Newco Common Stock for which Value Units were to be
exchanged pursuant to Section 1.2(a) of the Univisa Contribution Agreement
would otherwise be less than seven million five hundred thousand (7,500,000)
(after giving effect to the any prorations pursuant to Section 2.4, if
applicable), then notwithstanding anything to the contrary contained in this
Merger Agreement or in the Univisa Contribution Agreement, (i) a number of
Value Units equal to seven million five hundred thousand (7,500,000) minus the
aggregate number of shares of Newco Common Stock for which Value Units would
otherwise be exchanged pursuant to Section 1.2(a) of the Univisa Contribution
Agreement (after giving effect to any prorations pursuant to Section 2.4(a),
if applicable) (such difference, the "SPOT Difference") shall be exchanged for
Newco Common Stock (after giving effect to any prorations pursuant to Section
2.4, if applicable), (ii) the aggregate amount of cash for which Value Units
were otherwise to be exchanged pursuant to Section 1.2(a) of the Univisa
Contribution Agreement (after giving effect to any prorations pursuant to
Section 2.4, if applicable) shall be reduced by an amount equal to the product
of the SPOT Difference and the Standard Cash Consideration, and (iii) the
aggregate amount of cash, and shares of Newco Common Stock, if any, received
by holders on account of Shares for which Cash Elections or Stock Elections
had been made shall be adjusted in accordance with Section 2.4 first to
distribute the additional cash made available because of the adjustment
described in subsection (ii) above with respect to Shares for which a Cash
Election had been made but for which sufficient cash was not available and
second to distribute the additional shares of Newco Common Stock made
available because of such reallocation of cash with respect to Shares for
which Stock Elections had been made but for which sufficient shares of Newco
Common Stock were not available.

Agreement shall forthwith become void and there shall be no liability on the

Merger Agreement required by such amendment to the Reorganization Agreement
shall be effected by the parties hereto by action taken by their respective
Boards of Directors.

                   STOCK CONTRIBUTION AND EXCHANGE AGREEMENT
 
  This STOCK CONTRIBUTION AND EXCHANGE AGREEMENT (this "Agreement"), dated as
of September 20, 1996, is entered into by and among Grupo Televisa, S.A., a
corporation (sociedad anonima) organized under the laws of Mexico ("Parent"),
and Satellite Company, LLC, a Nevada limited liability company ("Contributor,"
and together with Parent, the "Contributing Group"), and Magellan
International, Inc., a Delaware corporation ("Newco") and Hughes
Communications, Inc., a California corporation ("HCI," and together with
Newco, the "Newco Group").
 
                                   RECITALS
 
  A. The respective Boards of Directors of HCI, Hughes Communications Galaxy,
Inc., a California corporation ("Galaxy") and certain other subsidiaries of
HCI (together with HCI and Galaxy, the "Hughes Parties") and PanAmSat
Corporation, a Delaware corporation ("PanAmSat"), have approved, and deem it
advisable and in the best interests of their respective companies and
stockholders to consummate the reorganization provided for pursuant to an
Agreement and Plan of Reorganization dated as of the date hereof by and
between, among others, Galaxy and PanAmSat (the "Reorganization Agreement").
 
  B. As a condition and inducement to the Hughes Parties and PanAmSat to enter
into the Reorganization Agreement (and effect the transactions contemplated
thereby), concurrently with the execution and delivery thereof, each member of
the Contributing Group and the Newco Group are entering into this Agreement.
 
  C. Pursuant to the Reorganization Agreement, Newco will acquire the business
of Galaxy and the business of PanAmSat by: (i) HCI causing the contribution of
assets and liabilities comprising the business of Galaxy to Newco in exchange
for shares of common stock of Newco (the "Asset Contribution"), (ii)
Contributor contributing its capital stock of Univisa, Inc., a Delaware
corporation ("Univisa"), which owns all of the outstanding stock of Univisa
Satellite Holdings, Inc., a Delaware corporation ("USHI"), which owns all of
the Class B Common Stock, par value $.01 per share, of PanAmSat (the "Class B
Common Stock"), to Newco in exchange for the consideration set forth in
Section 1.2 and (iii) the merger of a Delaware corporation ("Merger Sub"),
with and into PanAmSat, with PanAmSat remaining as the surviving corporation
(the "Merger").
 
  D. For federal income tax purposes, it is intended that the Asset
Contribution, the Univisa Contribution (as defined in Section 1.1) and the
Merger, together qualify as an exchange under the provisions of Section 351 of
the United States Internal Revenue Code of 1986, as amended (the "Code").
 
  E. In addition to the common stock of USHI, Univisa owns other assets and
Subsidiaries (as defined in Section 3.2), and as a condition to the
consummation of the transactions contemplated hereby, has agreed to distribute
all of its assets, Subsidiaries and Liabilities (as defined in Section 5.1(b))
(other than the stock of USHI, the Class B Common Stock and cash to pay
certain costs, expenses and Liabilities allocated to Univisa under this
Agreement) prior to the Closing (as defined in Section 2.1).
 
  F. As a condition to the consummation of the transactions contemplated
hereby, the Contributing Group has agreed to indemnify forever the Newco Group
against any and all Liabilities to be distributed prior to the Closing.

  In consideration of the foregoing and the mutual promises contained herein
and for other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the parties hereto, intending to be legally
bound, hereby agree as follows:
 
                                   Article I
 
                      Contribution and Exchange of Stock
 
  1.1 Contribution and Exchange of Stock. Upon the terms and subject to the
conditions contained herein, Contributor will contribute, convey, transfer,
assign and deliver to Newco, and Newco will acquire on the Closing Date, all
of the outstanding Univisa Stock (as defined in Section 3.2(a)), free and
clear of any claim, lien, pledge, option, charge, security interest,
encumbrance or other rights of third parties of any nature whatsoever
("Liens") (the "Univisa Contribution").
 
  1.2 Consideration for Stock.
 
  (a) Upon the terms and subject to the conditions contained herein, as
consideration for the Univisa Contribution, promptly after the Allocation
Determination, Newco shall, subject to Section 1.2(c), distribute to
Contributor consideration with an aggregate value deemed by the parties as of
the date hereof to be equal to the product of $30 multiplied by the number of
shares of Class B Common Stock owned by USHI immediately prior to the
Effective Time (the "Value Unit Consideration"), which shall be divided into
units with a deemed value of $30 each (each such unit, a "Value Unit"), each
such Value Unit to be exchanged at the election of Contributor for one of the
following (subject to Section 4.6 of the Reorganization Agreement):
 
    (i) for each Value Unit with respect to which a written election to
  receive a combination of Newco Common Stock and cash has been delivered by
  Contributor to Newco no later than the Election Deadline (a "Standard
  Election"), the right to receive (x) an amount in cash equal to one-half (
  1/2) of the Standard Cash Consideration plus (y) one-half ( 1/2) share of
  Newco Common Stock; or
 
    (ii) except as otherwise provided in Section 4.4 of the Reorganization
  Agreement, for each such Value Unit with respect to which a written
  election to receive solely Newco Common Stock has been delivered by
  Contributor to Newco no later than the Election Deadline (a "Stock
  Election"), the right to receive one (1) share of Newco Common Stock; or
 
    (iii) except as otherwise provided in Section 4.4 of the Reorganization
  Agreement, for each such Value Unit with respect to which a written
  election to receive solely cash has been delivered by Contributor to Newco
  no later than the Election Deadline (a "Cash Election"), the right to
  receive the Standard Cash Consideration.
 
  (b) Immediately upon the receipt of the consideration specified in Section
1.2, (a) seven million five hundred thousand (7,500,000) shares of Newco
Common Stock received by Contributor shall be repurchased by Newco for $225
million in cash.
 
  (c) The Trust Holdback shall be deducted from the Value Unit Consideration.
For purposes of this Section 1.2, the "Trust Holdback" shall be an amount in
cash equal to the sum of (i) an amount equal to the Known Liabilities Estimate
(as defined in Section 5.9) and (ii) $25 million, and five million (5,000,000)
shares of Newco Common Stock, provided, however, that if the Contributor shall
have received less than twelve million five hundred thousand (12,500,000)
shares of Newco Common Stock as consideration for the Univisa Contribution,
the Trust Holdback shall include all of the shares of Newco Common Stock
received by Contributor after giving effect to the repurchase of shares of
Newco Common Stock pursuant to Section 1.2(b) and the amount of cash shall be
increased by an amount equal to the product of (a) the difference between five
million (5,000,000) and the number of shares of Newco Common Stock received by
the Contributor after giving effect to the repurchase of shares of Newco
Common Stock pursuant to Section 1.2(b) and (b) the Standard Cash
Consideration. At the
 
                                      C-2

time the Contributor receives the Value Unit Consideration, Newco shall,
pursuant to a Collateral Trust Agreement substantially in the form attached
hereto as Exhibit A (the "Collateral Trust Agreement") and a Pledge and
Security Agreement substantially in the form attached hereto as Exhibit B (the
"Pledge Agreement," and together with the Collateral Trust Agreement, the
"Collateral Agreements"), assign and deliver the Trust Holdback to the trustee
named therein (the "Trustee"), pending the determination of Parent's and
Contributor's indemnification obligations, if any, as set forth in Section
8.2. Capitalized terms used in this Section 1.2 without meaning shall have the
meanings assigned to such terms in the Reorganization Agreement.
 
                                  Article II
 
                                    Closing

IX, the closing of the Univisa Contribution shall occur immediately after the
consummation of the Asset Contribution and immediately before, and on the same
day as, the consummation of the Merger (the "Closing Date"), at the offices of

another date, time or place is agreed to in writing by the parties hereto (the

material violation of any Law or Permit with respect to which all necessary
corrective action has not been taken. "Law" shall mean any applicable domestic
or foreign, federal, state or local laws, statutes, regulations, rules, codes,
ordinances, orders and governmental licenses, franchises, permits and
governmental authorizations enacted, adopted, issued or promulgated by any
Governmental Entity (including those pertaining to communications,
broadcasting, consumer protection, building, zoning, environmental and
occupational safety and health requirements and all requirements of the
Communications Act of 1934, as amended, or any successor statute, and the
rules and regulations of the Federal Communication Commission (the "FCC")) or
common law.
 
  (b) Univisa and its Subsidiaries possess, as of the date hereof, all
material permits, licenses, franchises, approvals, certificates, concessions,
privileges, immunities, consents or other authorizations issued or authorized
or required to be issued by any Governmental Entity (collectively, "Permits")
necessary to allow Univisa and its Subsidiaries to own or lease their assets
and to lawfully conduct their respective businesses.
 
  (c) Neither Univisa or its Subsidiaries, nor any of their respective
employees are officials or officers of any Governmental Entity or any
political party, and neither Univisa nor any of its Subsidiaries or affiliates
has taken, is taking or will take, or has allowed or will allow on its behalf
to be taken, any action which violated or would violate the United States
Foreign Corrupt Practices Act of 1977, the U.S. Export Administration Act, as
amended, or any laws of any jurisdiction to which such party or person is
subject, relating in each case to payments for the purpose of influencing an
act or decision of a government agency or official; provided, however, that
nothing in this sentence shall be deemed to subject any party or person to any
law to which such party or person would not otherwise be subject. Each of
Univisa and its Subsidiaries is in material compliance with all domestic and
foreign laws restricting or regulating the export of technology to foreign
countries.
 
  3.8 Litigation. Except as disclosed on Schedule 3.8, there is no suit,
action or proceeding pending or, to either member of the Contributing Group's
knowledge, threatened against or affecting Univisa or any of its Subsidiaries,
nor is there any written judgment, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against Univisa or any of its
Subsidiaries.
 
  3.9 Taxes. Each of Univisa and its Subsidiaries has timely filed (or has
obtained timely extensions for) all tax returns required to be filed by such
party completely and accurately in all material respects and has timely paid
(or Univisa has paid on behalf of any such Subsidiary), or has established an
adequate reserve for the
 
                                      C-7
<PAGE>
 
payment of, all material taxes which are required to be paid in respect of the
taxable period reflected in such returns or for periods since the most recent
date on which a return was filed. All taxes shown to be due on the tax returns
that have been filed by Univisa and each of its Subsidiaries have been timely
paid. Except as provided on Schedule 3.9, neither Univisa nor any of its
Subsidiaries has waived any statute of limitations in respect of taxes of
Univisa or any of its Subsidiaries. Except as set forth in Schedule 3.9, none
of the tax returns filed by Univisa or any of its Subsidiaries has been
examined by any taxing authority, and no audit, action, proceeding or
assessment is pending or, to either member of the Contributing Group's
knowledge, threatened by any taxing authority against Univisa or any of its
Subsidiaries. All material taxes which Univisa or any of its Subsidiaries is
required by law to withhold or to collect for payment have been duly withheld
and collected, and have been paid or accrued, reserved against and entered on
the books of Univisa. There are no material Liens for taxes (other than for
current taxes not yet due and payable) on the assets of Univisa or any of its
Subsidiaries. Neither Univisa nor any of its Subsidiaries has any gains from
intercompany transactions (within the meaning of the consolidated return
regulations of the Code) which will be recognized after the Closing Date.
Univisa has previously delivered or made available true and complete copies of
its federal income tax returns for each of the fiscal years ended December 31,
1992 through December 31, 1995. Except as set forth on Schedule 3.9, neither
Univisa nor any of its Subsidiaries is a party to or bound by any agreement
providing for the allocation or sharing of taxes with any entity which is not,
either directly or indirectly, a Subsidiary of Univisa. Neither Univisa nor
any of its Subsidiaries has filed or is required to file a consent pursuant to
or agreed to the application of Section 341(f) of the Code. Univisa is not a
"United States real property holding corporation" as defined in Section
897(c)(2) of the Code during the applicable period specified in Section
897(c)(1)(A)(ii) of the Code. For the purpose of this Agreement, the term
"tax" (and, with correlative meaning, the terms "taxes" and "taxable") shall
include all federal, state, local and foreign income, profits, franchise,
gross receipts, payroll, sales, employment, use, property, withholding, excise
and other taxes, duties or assessments of any nature whatsoever, together with
all interest, penalties and additions imposed with respect to such amounts.
 
  3.10 Material Contracts. Univisa has provided or made available to each
member of the Newco Group or its independent auditors (i) true and complete
copies of all Material Contracts, or (ii), with respect to such Material
Contracts that have not been reduced to writing, a written description
thereof, each of which is listed on Schedule 3.10. Except as set forth on
Schedule 3.10, neither Univisa nor any of its Subsidiaries is, or has received
any notice that, nor does the Contributing Group have any knowledge that, any
other party is in default in any respect under any such Material Contract. As
used in this Agreement, the term "Material Contract" means, as to any person
or entity, all written contracts, agreements, commitments, arrangements,
leases (including with respect to personal property), policies and other
instruments to which it or any of its Subsidiaries is a party or by which it
or any such Subsidiary is bound (other than intercompany arrangements which
will be cancelled, and for which mutual releases will be granted with respect
thereto, prior to the Closing) which, when assuming that all options to renew
or extend are exercised, (x) require payments to be made, individually or in
the aggregate, in excess of $1,000,000 per year for goods and/or services, or
(y) do not by their terms expire and are not subject to termination within six
months from the date of the execution and delivery thereof and require
payments to be made, individually or in the aggregate, in excess of
$1,000,000.
 
                                  Article IV
 
               Representations and Warranties of the Newco Group
 
  Each member of the Newco Group represents and warrants as of the date
hereof, on a joint and several basis, to each member of the Contributing Group
as follows:
 
  4.1 Organization, Standing and Power. Each member of the Newco Group is a
corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation, has all requisite corporate power
and authority necessary to own, lease and operate its properties and to carry
on its business as now being conducted, and is duly qualified, and in good
standing to own, lease and operate its properties and to conduct business in
each jurisdiction, domestic and foreign, in which the business it is
 
                                      C-8
<PAGE>
 
conducting, or the operation, ownership or leasing of its properties, makes
such qualification necessary, other than in such jurisdictions where the
failure so to qualify or be in good standing would not have a material adverse
economic impact on the assets or business of either member of the Newco Group
or impair the right or ability of the parties hereto to consummate the
transactions contemplated hereby. Each member of the Newco Group has
heretofore made available true, complete and correct copies of its Certificate
of Incorporation and Bylaws as currently in effect together with all
amendments thereto. No resolution has been adopted to amend any of such
Certificates of Incorporation or Bylaws except as expressly called for by this
Agreement. No member of the Newco Group (i) has been dissolved, adopted
resolutions to dissolve or acted in any way to accomplish, request or approve
such dissolution, (ii) is a party to any merger and (iii) has been declared
bankrupt, and, to each member of the Newco Group's knowledge, no action or
request is pending to declare it bankrupt. Newco has made available minute
books which contain complete and accurate records in all material respects of
all meetings, or consents in lieu thereof, of the shareholders and the Board
of Directors (including committees thereof) since its date of formation.
 
  4.2 Authority; No Violations; Consents and Approvals.
 
  (a) Each member of the Newco Group has all requisite corporate power and
authority to execute and deliver each of this Agreement and the Collateral
Agreements to which it is a party to perform its obligations hereunder and
thereunder and to effect the transactions contemplated hereby and thereby. The
execution, delivery and performance of each of this Agreement and the
Collateral Agreements to which it is party and the consummation of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of each member of the Newco Group. This
Agreement has been, and each of the Collateral Agreements to which it is a
party will be, duly executed and delivered by each member of the Newco Group
and assuming that each of this Agreement and the Collateral Agreements to
which it is a party constitutes the valid and binding agreement of the other
parties thereto, and assuming the consents, approvals, authorizations or
permits and filings or notifications referred to in paragraph (c) of this
Section 4.2 are duly and timely obtained or made, constitutes (or, with
respect to each of the Collateral Agreements to which it is a party, will
constitute when executed and delivered) a valid and binding obligation of each
member of the Newco Group enforceable in accordance with its terms except that
the enforcement hereby may be limited by the Bankruptcy Exception.
 
  (b) The execution, delivery and performance by each member of the Newco
Group of each of this Agreement and the Collateral Agreements to which it is a
party does not, and the consummation by each member of the Newco Group of the
transactions contemplated hereby and thereby will not, (x) conflict with or
result in any violation of, or default (with or without notice or lapse of
time, or both) under, or give rise to a right of termination, cancellation or
acceleration of any obligation or the loss of a material benefit under, or the
creation of a material Lien on assets or property, or right of first refusal
with respect to any material asset or property (any such conflict, violation,
default, right of termination, cancellation or acceleration, loss, creation or
right of first refusal, a "Newco Group Violation"), pursuant to any provision
of the Certificate of Incorporation or Bylaws of either member of the Newco
Group or, (y) except as to which requisite waivers or consents have been
obtained and, except as set forth on Schedule 4.2(b) hereto and assuming the
consents, approvals, authorizations or permits and filings or notifications
referred to in paragraph (c) of this Section 4.2 are duly and timely obtained
or made, result in any Newco Group Violation of any material loan or credit
agreement, note, mortgage, indenture, lease, or other material agreement,
obligation, instrument, permit, judgment, order, decree or Law applicable to
either member of the Newco Group or its properties or assets; provided,
however, that nothing in this Section 4.2 will be deemed to constitute a
representation or warranty by either member of the Newco Group as to any
antitrust law or requirement.
 
  (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, notice to, or permit from any Governmental Entity,
is required by or with respect to either member of the Newco Group in
connection with the execution and delivery by each member of the Newco Group
of each of this Agreement and the Collateral Agreements to which it is a party
or the consummation by each member of the Newco Group of the transactions
contemplated hereby and thereby, which if not obtained or made would have a
material adverse economic impact on the assets or business of such member, or
a member of the Contributing Group, or would
 
                                      C-9
<PAGE>
 
have a material adverse effect on either member of the Newco Group's ability
to consummate the transactions contemplated hereby or thereby, except for: (A)
the filing of a premerger notification and report form by the Newco Group
under the HSR Act and the expiration or termination of the applicable waiting
period thereunder; (B) the filing with the SEC of such reports under and such
other compliance with the Exchange Act and the rules and regulations
thereunder, as may be required in connection with this Agreement and the
Collateral Agreements and the transactions contemplated hereby and thereby;
(C) such filings and approvals as may be required by any applicable state
securities or "blue sky" laws; and (D) such other consents, approvals, orders,
authorizations, registrations, declarations, filings, notices and Permits set
forth in Schedule 4.2(c).
 
  4.3 Certain Representations. No member of the Newco Group has any plan or
intention to (and no such member has any plan or intention to cause or permit
Univisa, USHI or PanAmSat to) liquidate (completely or partially) or dissolve
Univisa or USHI, or merge, consolidate or combine Univisa or USHI with or into
Newco, PanAmSat or any other entity, other than a merger of USHI into Univisa
qualifying as a tax-free liquidation under Section 332 of the Code.
 
                                   Article V
 
                     Covenants Between Signing and Closing
 
  5.1 Interim Operations of Univisa and the Subsidiaries. During the period
from the date of this Agreement and continuing until the Closing Date, each
member of the Contributing Group agrees for itself and for its Subsidiaries
that:
 
    (a) New Business. Neither Univisa nor any of its Subsidiaries shall
  engage in or enter into any new business activities unrelated to their
  business activities as of the date hereof.
 
    (b) Payment of Liabilities. Univisa shall, and shall cause its
  Subsidiaries to, pay, discharge and satisfy any direct or indirect
  liability, indebtedness, obligation, commitment, expense, claim,
  deficiency, guaranty or endorsement of any type, whether accrued, absolute,
  contingent, matured, unmatured, known or unknown or otherwise ("Liability")
  that becomes due on or before the Closing.
 
    (c) Required Distributions. On or prior to the Closing Date and pursuant
  to agreements reasonably satisfactory to HCI (the "Distribution
  Agreements"), Univisa and its Subsidiaries shall, in redemption of a
  portion of the Univisa Stock, distribute and transfer (the "Distributions")
  to Parent, Contributor and their designees (other than Univisa or USHI)
  (collectively, Parent, Contributor and such distributees are referred to
  herein as the "Parent Distributees") all of Univisa's right, title and
  interest in any and all assets of Univisa and its Subsidiaries (or the
  proceeds of the disposition thereof), whether tangible or intangible and
  whether fixed, contingent or otherwise, including the stock of all of
  Univisa's Subsidiaries (the "Distributed Assets"); provided, however, that
  neither Univisa nor its Subsidiaries shall distribute or otherwise transfer
  (i) any shares of the USHI Stock, (ii) except as permitted under the
  Principal Stockholders Agreement, any shares of the Class B Common Stock
  and (iii) cash sufficient to pay all costs, liabilities and expenses
  (including taxes) incurred by Univisa or USHI in connection with the
  transactions contemplated by this Agreement that are the responsibility of
  Univisa which have not been paid prior to the Closing (collectively, the
  "Required Expenditures"). Such Distribution Agreements shall provide for,
  among other things, indemnification, on a joint and several basis, by the
  Parent Distributees in favor of Newco substantially similar to the
  indemnities provided by the Contributing Group in favor of Newco in Article
  VIII.
 
    (d) Assumption and Release of Liabilities. Prior to the Closing Date and
  pursuant to the Distribution Agreements, the Contributing Group shall
  assume, and shall cause the Parent Distributees to assume, any and all
  Liabilities of Univisa and USHI arising out of, or relating to, or
  connected with, occurrences, operations or events prior to, at or as of and
  through the last date the transactions contemplated by this Agreement and
  the Reorganization Agreement are consummated (including any Liabilities set
  forth on the Schedules hereto or on the Statement of Liabilities), or
  arising out of, or relating to, the Distributed Assets or other former
  assets of Univisa or USHI either prior to, at, as of, or after the Closing
  (the "Transaction Liabilities"). Concurrently with the Distributions, the
  Contributing Group shall, and shall cause its
 
                                     C-10

  release Univisa and USHI from any and all Transaction Liabilities or other
  Liabilities owing to such entities and (ii) use its reasonable best efforts
  to have Univisa and USHI released from any and all Transaction Liabilities
  owing to all other persons or entities.
 
    (e) Other Actions. Each member of the Contributing Group shall not take,
  and shall not permit any of its Subsidiaries to take or agree or commit to
  take, any action that results in any condition to the Closing not being
  satisfied in all material respects.
 
  5.2 Interim Operations of the Newco Group. During the period from the date
of this Agreement and continuing until the Closing Date, each member of the
Newco Group agrees that it will not take any action that results in any
condition to the Closing not being satisfied in all material respects.
 
  5.3 Access to Information. Each member of the Contributing Group shall (and
shall cause each of its Subsidiaries to) afford to the officers, employees,
accountants, counsel, financing sources and other representatives of each
member of the Newco Group reasonable access, during normal business hours
during the period prior to the Closing Date, to all of Univisa's properties,
books, contracts, commitments and records and those of Univisa's Subsidiaries
(including any tax returns or other tax related information pertaining to
Univisa and its Subsidiaries and including any information to be included in
any registration statement to be filed by Newco with respect to the Newco
Common Stock issued in connection with the transactions contemplated by this
Agreement and the Reorganization Agreement) and, during such period, each
member of the Contributing Group shall (and shall cause each of its
Subsidiaries to) furnish promptly to each member of the Newco Group all other
information concerning the business, properties and personnel of Univisa or
any Subsidiary as either member of the Newco Group may reasonably request
(including any tax returns or other tax related information pertaining to
Univisa or its Subsidiaries, as the case may be and including any information
to be included in any registration statement to be filed by Newco with respect
to the Newco Common Stock issued in connection with the transactions
contemplated by this Agreement and the Reorganization Agreement). Each member
of the Newco Group shall not, and shall cause its representatives not to, use
any information obtained pursuant to this Section 5.3 for any purpose
unrelated to the consummation of the transactions contemplated by this
Agreement.
 
  5.4 Legal Conditions, Filings and Consents. During the period from the date
of this Agreement and continuing until the Closing Date:
 
    (a) Each party will (i) cooperate with one another in determining whether
  any actions or filings are required in connection with obtaining any
  Governmental Entity approvals required to consummate the transactions
  contemplated by this Agreement (including, without limitation, furnishing
  all information required under the HSR Act), (ii) cooperate with one
  another in determining whether any actions, consents, approvals or waivers
  are required to be obtained from any corporate or equivalent governing body
  of any party, any of their subsidiaries, or any stockholder of the

  required to be obtained from any third parties, such as parties to any
  material contracts, in connection with the consummation of the transactions
  contemplated by this Agreement, (iii) endeavor in good faith to take all
  such actions or make any such filings, furnish information required in
  connection therewith, and seek in a timely manner to obtain any such
  actions, consents, approvals or waivers and (iv) promptly cooperate with
  and furnish information to each other in connection with any such
  requirements imposed upon any of them or any of their subsidiaries in
  connection with the Univisa Contribution and the other transactions
  contemplated by this Agreement. Without limiting the generality or effect
  of the foregoing, each party will take all commercially reasonable actions
  necessary to obtain (and will cooperate with each other in obtaining) in a
  timely manner any consent, authorization, order or approval of, or any
  exemption by, any Governmental Entity or other public or private third
  party, required to be obtained or made by such party in connection with the
  Univisa Contribution, this Agreement or the taking of any action
  contemplated hereby.
 
    (b) The parties acknowledge that the transactions described in this
  Agreement are an integral part of transactions contemplated by the
  Reorganization Agreement, that those transactions require the prior written
 
                                     C-11
<PAGE>
 
  consent of the FCC, that this Agreement will not be consummated prior to
  the Closing of the Asset Contribution, and, to the extent applicable to any
  of the stockholders of PanAmSat, that the obligations contained in Section
  5.4(a) apply with respect to any and all applications and filings made with
  Governmental Entities pursuant to Section 7.9 of the Reorganization
  Agreement.
 
  5.5 Notices of Certain Events.
 
  During the period from the date of this Agreement and continuing until the
Closing Date, each party shall promptly notify the other parties hereto of:
 
    (i) any notice or other communication from any person alleging that the
  consent of such person is or may be required in connection with such
  party's consummation of the transactions contemplated by this Agreement;
 
    (ii) any notice or other communication from any Governmental Entity in
  connection with such party's consummation of the transactions contemplated
  by this Agreement;
 
    (iii) any actions, suits, claims, investigations or proceedings commenced
  or, to the actual knowledge of the executive officers of the notifying

  such party or any of its subsidiaries;
 
    (iv) an administrative or other order or notification relating to any
  violation or claimed violation of Law by such party;
 
    (v) the occurrence or non-occurrence of any event the occurrence or non-

  material respect at or prior to the Closing Date; and
 
    (vi) any material failure of such party to comply with or satisfy any
  covenant, condition or agreement to be complied with or satisfied by it
  hereunder;
 
provided, however, that the delivery of any notice pursuant to this Section
5.5 shall not limit or otherwise affect the remedies available hereunder to
the party receiving such notice.
 
  5.6 Publicity. During the period from the date of this Agreement and
continuing until the Closing Date, the parties will consult with each other
and will mutually agree prior to the issuance of any press release or public
announcement pertaining to this Agreement or the transactions contemplated
hereby, and shall not issue any such press release or make any such public
announcement or permit any of their Subsidiaries to do the same prior to such
consultation and agreement, except as may be required by applicable Law or the
applicable rules of any securities exchange (including the Nasdaq National
Market) or except as otherwise permitted by the Reorganization Agreement, in
which case the party proposing to issue such press release or make such public
announcement shall use reasonable efforts to consult in good faith with the
other party before issuing any such press release or making any such public
announcement and except for the FCC filings and HSR filings contemplated
herein.
 
  5.7 Further Action. During the period from the date of this Agreement and
continuing until the Closing Date, each party hereto shall, subject to the
fulfillment at or before the Closing Date of each of the conditions of
performance set forth herein or the waiver thereof, perform such further acts
and execute such documents as may be reasonably required to effect the
transactions contemplated by this Agreement.
 
  5.8 Rights to "Univisa" Name. Prior to the Closing Date, the names of
"Univisa, Inc." and "Univisa Satellite Holdings, Inc." shall be changed such
that Univisa shall not be included in such names. After the Closing, Parent
and its Subsidiaries shall retain all right, title and interest in and to the
name "Univisa".
 
  5.9 Statement of Liabilities.
 
  (a) Contributor shall prepare and deliver to HCI, at least 90 days prior to
the anticipated Closing Date, a statement of all of the Liabilities of each of
Univisa and USHI estimated or projected as of the Closing Date
 
                                     C-12
<PAGE>
 
(such statement, as it may be revised pursuant to Section 5.9(b), is referred
to herein as the "Statement of Liabilities"). Within 30 days of such date of
delivery, HCI shall be entitled to verify the accuracy of the Statement of
Liabilities and shall determine in good faith the amount reasonably necessary
to satisfy in full all of the Liabilities set forth on such Statement,
including the amount reasonably necessary to satisfy on and after the Closing,
in full, all taxes for all taxable years and other periods ending on or before
or including (for the Pre-Closing Portions of any Straddle Periods (as defined
in Section 8.2(c)) the Closing Date, including, any and all such taxes
attributable to any and all distributions of assets by Univisa made in
contemplation of the transactions contemplated by this Agreement or the
Reorganization Agreement, including the distribution of the Distributed Assets
by Univisa to the Parent Distributees (such amount, as it may be revised
pursuant to Section 5.9(b), is referred to herein as the "Known Liabilities
Estimate"). During such 30 day period, HCI and its representatives shall have
access to the management, employees and counsel for Univisa and its
Subsidiaries and to such documents and other information relating to such
Statement as it shall reasonably request. Within five days of the expiration
of such 30 day period, HCI shall notify Contributor of any dispute with
respect to the Statement of Liabilities, and Contributor shall notify HCI of
any dispute with respect to the Known Liabilities Estimate, and any such
dispute(s) which cannot be resolved after good faith negotiations and in any
event within five days from the date Contributor or HCI, as the case may be,
is so notified, shall be referred to an arbitrator pursuant to Section 10.11,
whose determination on such matters shall be made within 30 days of such
referral and shall be final and binding on the parties and whose fees and
expenses shall be paid by the party who does not prevail in such action,
unless the arbitrator determines another method is more equitable.
 
  (b) Contributor shall prepare and deliver to HCI, at least 10 days before
the anticipated Closing Date, an amendment to the Statement of Liabilities,
setting forth any changes that have occurred (or are expected to occur) from
the period beginning on the date when the Statement of Liabilities was
provided to HCI and ending on the Closing Date. Within five days of such date
of delivery, HCI shall be entitled to verify the accuracy of the amended
Statement of Liabilities and shall determine in good faith whether the Known
Liabilities Estimate should be revised to satisfy in full all of the
Liabilities set forth on such amended Statement. During such five day period,
HCI and its representatives shall have access to the management, employees and
counsel for Univisa and its Subsidiaries and to such documents and other
information relating to such Statement as it shall reasonably request.
Immediately after the expiration of such five day period, HCI shall notify
Contributor of any dispute with respect to such amended Statement, and
Contributor shall notify HCI of any dispute with respect to any revisions to
the Known Liabilities Estimate, and any such dispute(s) which cannot be
resolved after good faith negotiations prior to the Closing, shall be referred
to an arbitrator pursuant to Section 10.11, whose determination on such
matters shall be made as promptly as practicable (either before or after the
Closing, however, such arbitration shall in no way delay the Closing if all
other conditions to the Closing set forth in Article VI have been satisfied or
waived by the party for whose benefit such conditions exist) and shall be
final and binding on the parties and whose fees and expenses shall be paid by
the party who does not prevail in such action, unless the arbitrator
determines another method is more equitable. Any adjustments that are required
as a result of such arbitration shall be made as promptly as practicable after
such determination.
 
  (c) Notwithstanding the failure to include any Liability on the Schedule of
Liabilities, or the inclusion of an amount different from the actual amount
needed to satisfy in full any Liability set forth on the Schedule of
Liabilities, or any determination of an arbitrator under Section 10.11, the
actual amount of all Transaction Liabilities shall remain and be the
responsibility of the Contributing Group, and the Contributing Group shall
indemnify and save and hold harmless in full the Newco Group with respect to
any such Transaction Liabilities to the extent set forth in Section
8.2(a)(ii).
 
  (d) When making any determinations under this Section 5.9, the arbitrator
may consider the following: the reasonable likelihood of future claims of the
type or class of claims which is the subject of dispute, the Contributing
Group's ability to satisfy current and future claims and the availability of
insurance. No amounts will be required to be allocated to the Known
Liabilities Estimate with respect to Univisa's obligations under its
licensing/distribution agreements to distribute Parent's programming (although
other obligations under or related to such agreements could be allocated to
the Known Liabilities Estimate, for example, Liabilities associated with
indemnification obligations under such contracts).

  5.10 Trustee.
 
  (a) Each party acknowledges that the Collateral Agreements have not been
reviewed by any Trustee, and that upon the designation of such Trustee, such
Trustee may request that certain revisions be made to such agreements. Each
party will cooperate with one another in good faith to reach mutual agreement
on such revisions.
 
  (b) Prior to the Closing and pursuant to the Collateral Agreements, the
parties shall select a Trustee with respect to the Collateral Agreements which
Trustee shall be a bank or trust company in good standing, organized under the
laws of the United States of America or any State, doing business in or having
a correspondent relationship with a bank or trust company doing business in
the Borough of Manhattan, City of New York, State of New York, and having a
capital and surplus (including subordinated capital notes and earned surplus)
aggregating at least $500,000,000. If the parties are unable to find a bank or
trust company that satisfies the foregoing conditions and that is willing to
serve as the Trustee, then each of the parties shall use its reasonable best

  6.1 Conditions to Each Party's Obligation to Effect the Univisa

Contribution shall be subject to the satisfaction on or prior to the Closing

  promulgated, enforced or entered any statute, rule, regulation or order
  (whether temporary, preliminary or permanent) which is in effect and which

  transactions contemplated by this Agreement; provided, however, that the
  parties shall use their commercially reasonable efforts to cause any such
  decree, judgment, injunction or other order to be vacated or lifted.
 
    (b) HSR Act. Any waiting period applicable to the consummation of the
  transactions contemplated hereby under the HSR Act shall have expired or
  been terminated, and no action shall have been instituted by the Department
  of Justice or the Federal Trade Commission challenging or seeking to enjoin
  the consummation of the transactions contemplated hereby, which action
  shall not have been withdrawn by the party instituting such action or
  dismissed or terminated pursuant to a final, non-appealable judgment of a
  United States federal court.
 
    (c) Other Approvals. All other approvals or orders by Governmental
  Entities required to be obtained, and all filings, notices or declarations
  required to be made before any Governmental Entity, by any party prior to
  the consummation of the transactions contemplated hereunder shall have been
  obtained from, and made with, all required Governmental Entities, except
  for such authorizations, consents, waivers, orders, approvals, filings,
  notices or declarations, the failure to obtain or make would not be likely
  to have a material adverse effect at or after the Closing Date, on Newco
  and its Subsidiaries taken as a whole, or on Univisa and its Subsidiaries
  taken as a whole.
 
    (d) No Conversion or Exchange. The Certificate of Incorporation of

  to that effect. Notwithstanding the foregoing, the obligations of the
  Contributing Group to effect the transactions contemplated by this
  Agreement shall not be relieved by the failure of the foregoing conditions
  if such failure is the result, directly or indirectly, of any material
  breach by either member of the Contributing Group of any of its material
  obligations under this Agreement.
 
    (d) Ancillary Agreements. Each member of the Newco Group shall have
  executed and delivered the Collateral Trust Agreement, Newco shall have

  of which shall be in full force and effect.
 
    (e) Legal Opinion. Contributor shall have received opinions addressed to
  each member of the Contributing Group of counsel to each member of the

  enforceability of each of this Agreement and the Collateral Agreements to
  which it is a party against each member of the Newco Group, with such

  contemporaneously delivered to Contributor.

  warranties of each member of the Contributing Group set forth in this
  Agreement shall be true and correct in all material respects as of the date

    Collateral Agreements, and the enforceability of each of this Agreement
    and the Collateral Agreements against each member of the Contributing
    Group, and the validity and perfection of the security interests

    of the Contributing Group; provided, that copies of such certificates
    still be contemporaneously delivered to HCI.
 
      (ii) HCI shall have received an opinion addressed to each member of
    the Newco Group of Fried, Frank, Harris, Shriver & Jacobson, dated as

    (iv) distribute or otherwise transfer Class B Common Stock to Newco or
  any other person, or contribute or otherwise transfer the Class A Common
  Stock of PanAmSat or the Common Stock of PanAmSat to Univisa or USHI.
 
  7.5 Confidentiality.
 
  (a) Preservation of Confidentiality. In connection with the negotiation of
this Agreement, the preparation for the consummation of the transactions
contemplated hereby and the performance of obligations hereunder, each party
acknowledges that it will have access to confidential information relating to
the other parties. The parties shall treat such information as confidential,
preserve the confidentiality thereof and not disclose such information, except
to their respective affiliates, Subsidiaries, advisors, representatives and
consultants in connection with the transactions contemplated hereby, and
except as required by Law or the applicable rules of any securities exchange.
Each of the parties agrees to maintain in confidence, and not to disclose to
any third party, any ideas, methods, developments, inventions, improvements
and business plans and information which are the confidential information of
any other party, except to their respective affiliates, Subsidiaries,
advisors, representatives and consultants in connection with the transactions
contemplated hereby, and except as required by Law or the applicable rules of
any securities exchange. If, however, confidential information is disclosed,
the disclosing party shall immediately notify each of the other parties in
writing and take all steps required to prevent further disclosure.
 
  (b) Property Right in Confidential Information. Until the Closing Date, all
confidential information shall remain the property of the party who originally
possessed such information. In the event of the termination of this Agreement
for any reason whatsoever, each party shall return to the other parties, all
documents, work papers and other material (including all copies thereof)
obtained from such parties in connection with the transactions contemplated
hereby and will use commercially reasonable efforts, including, without
limitation, instructing its employees and others who have had access to such
information, to keep confidential and not to use any such information, unless
such information is now, or is hereafter disclosed, through no act or omission
of such party, in any manner making it available to the general public. If any
party is required by any Law or the applicable
 
                                     C-17
<PAGE>
 
rules of any securities exchange to disclose any confidential information, it
shall provide the other parties with prompt notice of such request so that
such other parties may seek an appropriate protective order or other
appropriate remedy and/or waive compliance with the provisions of this
Agreement. If, in the absence of a protective order or other remedy or the
receipt of such a waiver, a party is nonetheless compelled by Law or the
applicable rules of any securities exchange to disclose confidential
information, then such party may disclose that portion of the confidential
information which such Law or rule requires to be disclosed, provided that
such party uses its reasonable efforts to preserve the confidentiality of the
information, whereupon such disclosure shall not constitute a breach of this
Agreement.
 
  (c) Termination of Agreement. Subject to any Law, each party hereto shall,
and shall cause their Subsidiaries, affiliates, advisors, representatives and
consultants who obtain such information to, hold in confidence all such non-
public information until such time as such information is otherwise publicly
available, except as required by Law or the applicable rules of any securities
exchange, and, if this Agreement is terminated and if so requested by another
party, each party and its affiliates will, and will cause their Subsidiaries,
affiliates, advisors, representatives and consultants who obtain such
information to, deliver to such other party all documents, work papers and
other material (including copies extracts and summaries thereof) obtained by
or on behalf of any of them directly or indirectly as a result of this
Agreement or in connection herewith, whether so obtained before or after the
execution hereof.

  (a) Representations and Warranties. All statements contained in the
Schedules hereto or in any certificate or instrument of conveyance delivered
by or on behalf of the parties pursuant to this Agreement or in connection
with the transactions contemplated hereby shall be deemed to be
representations and warranties by the parties hereunder. The representations
and warranties of each party contained herein or made hereunder shall survive
until the expiration of all applicable statutes of limitations (including,
without limitation, all periods of extension, whether automatic or
permissive), without regard to any investigation made by any of the parties
hereto. All claims for indemnification under Sections 8.2(a)(i)(m) or
8.2(b)(i) (other than any claim for indemnification solely with respect to a
breach of the representation in Section 4.3) must be asserted on or prior to
the date of termination of the foregoing survival periods. If a claim for
indemnification under Sections 8.2(a)(i)(m) or 8.2(b)(i) (other than any claim
for indemnification solely with respect to a breach of the representation in
Section 4.3) is made before the expiration of the applicable survival period
referred to above, then (notwithstanding the expiration of such survival
period) the representation or warranty applicable to such claim shall survive
until, but only for purposes of, the resolution of such claim.
 
  (b) Covenants. All of the covenants and agreements of each party contained
herein or made hereunder shall survive indefinitely. Claims for
indemnification under Sections 8.2(a)(i)(n), 8.2(b)(i) (solely with respect to
a breach of the representation in Section 4.3) or 8.2(b)(ii) shall survive
indefinitely and may be asserted indefinitely.
 
  (c) General Indemnity. Claims may be made for general indemnity and to be
saved and held harmless under Section 8.2(a)(ii) at any time, and from time to
time, no matter when the claim, or the event or act giving rise to the claim,
occurs or arises.
 
  8.2 Indemnification.
 
  (a) By Parent and Contributor.
 
    (i) Parent and Contributor, jointly and severally, shall indemnify, save

  Subsidiaries, and its and their respective representatives, successors and
  assigns, from and against any and all costs, losses (including diminution
  in value), taxes, Liabilities,
 
                                     C-18

  (whether or not arising out of third-party claims), including interest,
  penalties, costs of mitigation, losses in connection with any Environmental
  Law (including any clean-up or remedial action), lost profits and other
  losses (including consequential damages), damages to the environment,
  reasonable attorneys' fees and all amounts paid in investigation, defense
  or settlement of any of the foregoing (collectively, "Damages"), incurred
  in connection with, arising out of, resulting from or incident to (m) any
  breach of any representation or warranty or the inaccuracy of any
  representation, made by either member of the Contributing Group in or
  pursuant to this Agreement and (n) any breach of any covenant or agreement
  made by either member of the Contributing Group in or pursuant to this
  Agreement.
 
    (ii) In addition, without duplication, and as a condition to the
  consummation of the transactions contemplated hereby by each member of the
  Newco Group, Parent and Contributor, jointly and severally, shall
  indemnify, save and hold harmless each member of the Newco Group, its
  affiliates and Subsidiaries, and its and their respective representatives,
  successors and assigns from and against any and all Damages incurred in
  connection with, arising out of, resulting from or incident to (o)
  administering either of the Collateral Agreements, (p) any and all
  Transaction Liabilities, excluding any and all tax Liabilities, (q) any and
  all taxes of Univisa or USHI (or any other entity that is or was at any
  time a Subsidiary or other affiliate of Univisa or USHI or either of them)
  for all taxable years and other periods ending on or before or including
  (for the Pre-Closing Portions of any Straddle Periods) the Closing Date
  ("Pre-Closing Periods"), including any and all such taxes attributable to
  any and all distributions of assets by Univisa or its Subsidiaries made in
  contemplation of the transactions contemplated by this Agreement or the
  Reorganization Agreement, including the distribution of the Distributed
  Assets by Univisa or its Subsidiaries to the Parent Distributees, (r) any
  and all taxes imposed on taxable income or gain recognized by Univisa or
  USHI for United States federal, state or local income tax purposes with
  respect to the Class B Common Stock held by USHI solely with respect to the
  Asset Contribution, the Univisa Contribution, the Merger and/or the
  consummation of any other agreement expressly provided for in this
  Agreement or the Reorganization Agreement, in each case in accordance with
  their respective terms, but not with respect to any income or gain
  recognized on the sale, exchange or other disposition of the Class B Common
  Stock after the Closing Date, (s) any and all Liabilities imposed upon
  either member of the Newco Group by reason of Newco's status as transferee
  of the Univisa Stock and (t) any and all taxes of either member of the
  Newco Group imposed on the actual or constructive receipt of indemnity
  payments in respect of Damages under this Section 8.2(a) to the extent
  necessary to make the after-tax amount of such payments equal to the amount
  of such Damages incurred by the Newco Group; provided, however, that
  notwithstanding the foregoing, Parent and Contributor shall not be
  responsible for payment of, and shall not be required to indemnify, save or
  hold harmless any member of the Newco Group, its affiliates or Subsidiaries
  or its or their respective representatives, successors or assigns from or
  against, any and all Damages incurred in connection with, arising out of,
  resulting from or incident to (1) any breach of any representation,
  warranty, covenant or agreement, or the inaccuracy of any representation,
  warranty, covenant or agreement, in any case, made by either member of the
  Newco Group in Sections 4.3, 7.3 or 7.4 of this Agreement, or (2) any
  transactions consummated after the Closing on the Closing Date, other than
  transactions required to be effected on the Closing Date pursuant to this
  Agreement or the Reorganization Agreement.
 
    (iii) Payments by a member of the Newco Group, its affiliates and
  Subsidiaries, and its and their respective representatives, successors and
  assigns, of amounts for which indemnification is sought hereunder, shall
  not be a condition precedent to recovery hereunder.
 
    (iv) Notwithstanding the foregoing, neither HCI, nor its affiliates or
  Subsidiaries (other than Newco) shall be entitled to be indemnified for
  Damages under this Section 8.2 to the extent that (A) such Damages arise
  out of or result from HCI's ownership of Newco Common Stock and (B) Newco
  is being fully indemnified hereunder with respect to such Damages.
 
  (b) By the Newco Group. Newco and HCI, jointly and severally, shall
indemnify and save and hold harmless Parent, Contributor, their respective
affiliates and subsidiaries, and their respective representatives,
 
                                     C-19
<PAGE>
 
successors and assigns from and against any and all Damages incurred in
connection with, arising out of, resulting from or incident to (i) any breach
of any representation or warranty or the inaccuracy of any representation,
made by either member of the Newco Group in or pursuant to this Agreement; or
(ii) any breach of any covenant or agreement made by either member of the
Newco Group in or pursuant to this Agreement.
 
  Payments by Parent, Contributor, their respective affiliates and
Subsidiaries, and their respective representatives, successors and assigns, of
amounts for which indemnification is sought hereunder, shall not be a
condition precedent to recovery hereunder.
 
  (c) Straddle Periods. Responsibility for payment of any and all taxes which
are reported on tax returns which cover both Pre-Closing Periods and periods
after the Closing ("Post-Closing Periods") (collectively, "Straddle Periods")
shall be apportioned, subject to and except as set forth in Section
8.2(a)(ii), between Contributor, on the one hand, and Univisa, on the other
hand, based on the actual operations and transactions of Univisa and USHI (and
any entity that is or was at any time during a Straddle Period a Subsidiary or
other affiliate of Univisa) during the portion of such Straddle Period ending
on the Closing Date, including the consummation of the Univisa Contribution,
the Asset Contribution, the Merger and the other transactions required to be
effected pursuant to this Agreement and the Reorganization Agreement, in
accordance with their respective terms (the "Pre-Closing Portion of a Straddle
Period"), and the portion thereof beginning on the day after the Closing Date.
Each such period shall be deemed to be a separate taxable period.
 
  (d) Filings. All tax returns of Univisa and USHI (and any entity that is or
was at any time during a relevant taxable period a Subsidiary or other
affiliate of Univisa) for Pre-Closing Periods and Straddle Periods shall be
prepared at Contributor's cost and expense, and under the direction and
control of Contributor; provided, however, that any portion of any Straddle
Period return for which Univisa has liability hereunder shall be subject to
the review and consent of Univisa, which consent shall not be unreasonably
withheld.
 
  (e) Refunds. Any refunds or credits of any and all taxes received by or
credited to Univisa or USHI (or any entity that is or was at any time during a
Pre-Closing Period a Subsidiary or other affiliate of Univisa) attributable to
Pre-Closing Periods ("Contributor's Refunds") shall be for the benefit of
Contributor, and Newco and HCI shall use reasonable efforts to obtain and
promptly pay over to Contributor any Contributor's Refunds.
 
  (f) Defense of Claims. If a claim for Damages (other than a claim for
Damages pursuant to clauses (q), (r), (s) or (t) of Section 8.2(a)(ii) which
shall be governed solely by the provisions of Section 8.2(g)(ii)) (a "Claim")
is to be made by a party entitled to indemnification hereunder against the
indemnifying party, the party claiming such indemnification shall give written
notice (a "Claim Notice") to the indemnifying party as soon as practicable
after the party entitled to indemnification becomes aware of any fact,
condition or event which may give rise to Damages for which indemnification
may be sought under this Section 8.2. If any lawsuit or enforcement action is
filed against any party entitled to the benefit of indemnity hereunder,
written notice thereof shall be given to the indemnifying party as promptly as
practicable (and in any event within 15 calendar days after the service of the
citation or summons). The failure of any indemnified party to give timely
notice hereunder shall not affect rights to indemnification hereunder, except
to the extent that the indemnifying party demonstrates actual damage caused by
such failure. After such notice, if the indemnifying party shall acknowledge
in writing to the indemnified party that the indemnifying party shall be
obligated under the terms of its indemnity hereunder in connection with such
lawsuit or action and so long as the indemnifying party has not committed a
Make-Whole Breach (as such term is defined in the Collateral Trust Agreement),
then the indemnifying party shall be entitled, if it so elects at its own
cost, risk and expense, (i) to take control of the defense and investigation
of such lawsuit or action, (ii) to employ and engage attorneys of its own
choice and reasonably satisfactory to the indemnified party to handle and
defend the same unless the named parties to such action or proceeding include
both the indemnifying party and the indemnified party and the indemnified
party has been advised in writing by counsel that there may be one or more
legal defenses available to such indemnified party that are different from or
additional to those available to the indemnifying party, in which event the
indemnified party shall be entitled, at the indemnifying party's cost, risk
and expense, to separate counsel of its own choosing, and (iii) to compromise
or settle such claim, which compromise or settlement can be made without the
written consent of
 
                                     C-20
<PAGE>
 
the indemnified party, so long as such compromise or settlement solely
provides for monetary relief and includes an unconditional release of each
indemnified party from all Liabilities arising out of such claim, and in other
instances will require the written consent of the indemnified party, such
consent not to be unreasonably withheld; provided, however, if such lawsuit or
action involves a breach of the representations and warranties set forth in
Section 3.2, (with respect to the ownership of Univisa or USHI), then,
notwithstanding the foregoing, the indemnified party shall be entitled to
control such remediation or resolution, including to take control of the
defense and investigation of such lawsuit or action, to employ and engage
attorneys of its own choice to handle and defend the same, at the indemnifying
party's cost, risk and expense, and to compromise or settle such Claim;
provided, further, however, that such Claim shall not be compromised or
settled without the written consent of the indemnifying party, which consent
shall not be unreasonably withheld. If the indemnifying party fails to assume
the defense of such claim within 15 calendar days after receipt of the Claim
Notice, the indemnified party against which such claim has been asserted will
(upon delivering notice to such effect to the indemnifying party) have the
right to undertake, at the indemnifying party's cost and expense, the defense,
compromise or settlement of such claim on behalf of and for the account and
risk of the indemnifying party. The indemnifying party shall reimburse, as an
interim measure during the pendency of any Claim, the indemnified party on a
monthly basis for all reasonable legal or other expenses incurred in
connection with investigating or defending any such Claim. Any such interim
reimbursement payments which are not made within 30 days of a request for
reimbursement, shall bear interest at the rate of 9% per annum from the date
of such request. In the event the indemnified party assumes the defense of the
claim, the indemnified party will keep the indemnifying party reasonably
informed of the progress of any such defense, compromise or settlement. The
indemnifying party shall be liable for any settlement of any action effected
pursuant to and in accordance with this Section 8.2 and for any final judgment
(subject to any right of appeal), and the indemnifying party agrees to
indemnify and hold harmless an indemnified party from and against any Damages
by reason of such settlement or judgment.
 
  The indemnified party shall cooperate in all reasonable respects with the
indemnifying party and such attorneys in the investigation, trial and defense
of such lawsuit or action and any appeal arising therefrom; provided, however,
that the indemnified party may, at its own cost, participate in the
investigation, trial and defense of such lawsuit or action and any appeal
arising therefrom. The parties shall cooperate with each other in any
notifications to insurers.
 
  (g) Cooperation in Tax Matters.
 
    (i) Each member of the Contributing Group and the Newco Group shall (a)
  each provide one another (and its counsel) with such assistance, and
  cooperate fully with one another, as and to the extent reasonably requested
  by any of them in connection with the preparation or filing of any tax
  return for Pre-Closing Periods and Straddle Periods, any Contributor's
  Refund or any defense or settlement of any Tax Matter (including, without
  limitation, in the case of Newco, by providing any necessary powers of
  attorney in respect of Univisa or USHI in connection with any Tax Matter
  relating to any tax Liability for which Parent and Contributor would be
  liable under Section 8.2(a)(ii)), relating to any tax Liability of Univisa,
  USHI or any of their respective Subsidiaries or affiliates, (b) retain and
  provide one another with any records or other information that may be
  relevant to any such tax return, Contributor's Refund or Tax Matter, and
  (c) provide one another with any final determination of any audit or
  examination, proceeding, or determination that affects any amount required
  to be shown on any such tax return of the other(s) (or any Subsidiary or
  affiliate of Univisa) for any period. Without limiting the generality of
  the foregoing, each member of the Contributing Group and the Newco Group
  shall each retain, until the applicable statutes of limitations (including
  any extensions) have expired, copies of all tax returns, supporting work
  schedules, and other records or information that may be relevant to any
  such tax return, Contributor's Refund or Tax Matter and shall not destroy
  or otherwise dispose of any such records without first providing the other
  party with a reasonable opportunity to review and copy the same.
 
    (ii) Newco and HCI shall promptly notify Parent and Contributor in
  writing upon receipt by Newco, HCI or any of their respective affiliates or
  Subsidiaries (including Univisa and USHI) of notice of any pending or
  threatened tax audits or assessments which may affect the tax Liabilities
  of Univisa or USHI (or
 
                                     C-21
<PAGE>
 
  any entity that is or was at any time a Subsidiary or other affiliate of
  Univisa or USHI) for which Parent and Contributor would be liable under
  clauses (q), (r), (s) or (t) of Section 8.2(a)(ii), and Parent and
  Contributor shall promptly notify Newco and HCI in writing upon receipt by
  Parent, Contributor or any of their respective affiliates of notice of any
  pending or threatened tax audits or assessments which may affect the tax
  Liabilities of Univisa or USHI (or any entity that is or was at any time a
  Subsidiary or other affiliate of Univisa) for which Newco and HCI would be
  liable under this Agreement. The failure of any indemnified party to give
  timely notice hereunder shall not affect rights to indemnification
  hereunder, except to the extent that the indemnifying party demonstrates
  actual damage caused by such failure. Contributor shall have the right to
  represent and control Univisa's and USHI's and any of their respective
  affiliates' or Subsidiaries' interests in any audit or proceeding,
  including any audit, examination, assessment, notice of deficiency or other
  adjustment or proposed adjustment, or administrative or judicial
  proceeding, the settlement of any of the foregoing, any waiver or extension
  of the statute of limitations, or the filing of any amended return (a "Tax
  Matter"), involving a tax Liability for which Contributor and Parent would
  be liable under Section 8.2(a)(ii) and to employ counsel of its choice at
  its expense; provided, however, Newco shall represent and control the
  interests of Univisa and USHI if Contributor commits a Make-Whole Breach.
  Newco and HCI shall have the right to represent and control Univisa's and
  USHI's (and any of their respective affiliates' or Subsidiaries') interests
  in any Tax Matter involving a tax Liability for which Newco and HCI would
  be liable under this Agreement and to employ counsel of their choice at
  their expense. With respect to any Tax Matter in which Contributor
  exercises its right to represent and control the interests of Univisa and
  USHI, Contributor and Newco shall fully cooperate with one another and
  shall, except as they may otherwise agree, jointly attend all meetings and
  proceedings and jointly prepare all protests, briefs and other documents.
 
  (h) Brokers and Finders. Pursuant to the provisions of this Section 8.2,
each member of the Newco Group, on the one hand, and each member of the
Contributing Group, on the other hand, shall indemnify, hold harmless and
defend one another from the payment of any and all broker's and finder's
expenses, commissions, fees or other forms of compensation which may be due or
payable from or by the indemnifying party, or may have been earned by any
third party acting on behalf of the indemnifying party in connection with the
negotiation and execution hereof and the consummation of the transactions
contemplated hereby.
 
  (i) Treatment of Indemnity Payments. Newco, HCI and Contributor agree to
treat all indemnity payments made pursuant to this Agreement as adjustments to
the consideration for the Univisa Contribution set forth in Section 1.2.
 
  (j) Holdback Amount. As security for the due and punctual payment of each
and all present and future indemnities, Liabilities and obligations of every
type and description of either member of the Contributing Group at any time
arising under, pursuant to, or in respect of this Article VIII, at the
Closing, each member of the Contributing Group shall duly execute and deliver
each of the Collateral Agreements and all assignments, financing statements
and other instruments required thereunder or pursuant thereto. Each of the
parties hereto agrees and acknowledges that the Trust Holdback shall not be
the exclusive source of indemnification for the Newco Group from Contributor
and Parent pursuant to this Article VIII, but that the Newco Group may proceed
directly against Contributor and Parent at law, equity or otherwise.

                           Termination and Amendment
 
  9.1 Termination. This Agreement may be terminated at any time prior to the
Closing Date:
 
    (a) by mutual written consent of Contributor and HCI;
 
    (b) by Contributor or HCI, so long as such party is not in material
  breach of its material obligations hereunder, if the Univisa Contribution
  shall not have been consummated on or before the date that is 15 months
  from the date of this Agreement;
 
                                     C-22
<PAGE>
 
    (c) by Contributor, if the conditions set forth in Section 6.2 shall not
  have been complied with or performed on or prior to the Closing Date and
  Contributor shall not have materially breached any of its material
  representations, warranties, covenants or agreements contained herein, and
  such noncompliance or nonperformance shall not have been cured or
  eliminated (or by its nature cannot be cured or eliminated) on or before
  the Closing Date;
 
    (d) by HCI, if the conditions set forth in Section 6.3 shall not have
  been complied with or performed on or prior to the Closing Date and HCI
  shall not have materially breached any of its material representations,
  warranties, covenants or agreements contained herein, and such
  noncompliance or nonperformance shall not have been cured or eliminated (or
  by its nature cannot be cured or eliminated) on or before the Closing Date;
 
    (e) by Contributor or HCI if any injunction or order of a court or other
  competent authority preventing the consummation of the Univisa Contribution
  shall have become permanent, final and non-appealable; or
 
    (f) by Contributor or by HCI if for any reason the Reorganization
  Agreement shall have been terminated; provided, however, that the right to
  terminate this Agreement under this Section 9.1(f) shall not be available
  to Contributor if the Reorganization Agreement shall have been terminated
  by PanAmSat pursuant to either Section 9.1(e), Section 9.1(f) or Section
  9.1(g) thereof.
 
  9.2 Effect of Termination. In the event of termination of this Agreement by
any party as provided in Section 9.1, (a) written notice thereof shall
forthwith be given to the other parties specifying the provision hereof
pursuant to which such termination is made and (b) this Agreement shall
forthwith become void and there shall be no Liability on the part of any party
hereto or their respective Subsidiaries, affiliates, officers, directors or
stockholders, except to the extent that such termination results from the
willful or reckless breach by a party hereto of any of its representations or
warranties, or of any of its covenants or agreements, in each case, as set
forth in this Agreement. The provisions of Sections 7.5 and 10.2 shall survive
any termination of this Agreement, unless otherwise agreed by the parties.
 
  9.3 Amendment. Subject to applicable law, this Agreement may be amended,
modified or supplemented only by written agreement of the parties at any time
prior to the Closing Date with respect to any of the terms contained herein.
 
  9.4 Extension; Waiver. At any time prior to the Closing Date, and subject to
applicable law, the parties hereto, by action taken or authorized by their
respective Boards of Directors, may, to the extent legally allowed: (i) extend
the time for the performance of any of the obligations or other acts of the
other parties hereto; (ii) waive their rights with respect to any inaccuracies
in the representations and warranties of the other parties contained herein or
in any document delivered pursuant hereto; and (iii) waive their rights with
respect to compliance with any of the agreements of the other parties or
conditions contained herein to their respective obligations. Any agreement on
the part of a party hereto to any such extension or waiver shall be valid only
if set forth in a written instrument signed on behalf of such party. The
failure of any party hereto to assert any of its rights hereunder shall not
constitute a waiver of such rights.
 
                                   Article X
 
                              General Provisions

  10.4 Interpretation. When a reference is made in this Agreement to Sections
or Articles, such reference shall be to a Section or Article of this Agreement
unless otherwise indicated. The table of contents and headings contained in
this Agreement are for reference purposes only and shall not affect in any way
the meaning or interpretation of this Agreement. Whenever the word "include",
"includes" or "including" are used in this Agreement, they shall be deemed to
be followed by the words "without limitation". The phrase "made available" in
this Agreement shall mean that the information referred to has been made
available if requested by the party to whom such information is to be made
available. This Agreement shall not be construed for or against either party
by reason of the authorship or alleged authorship of any provision hereof or
by reason of the status of the respective parties.
 
  10.5 Entire Agreement. This Agreement (together with any documents and
instruments referred to herein, including exhibits and schedules) constitutes
the entire agreement and supersedes all prior agreements and understandings,
both written and oral, among the parties with respect to the subject matter
hereof and is not intended to confer upon any person other than the parties
hereto any rights or remedies hereunder.
 
  10.6 Assignment. Except for assignments by a member of the Holding Group to
any affiliate or Subsidiary of such member with respect of some or all of its
rights under Article VIII (which assignment can be made without the written
consent of Contributor), neither this Agreement nor any of the rights,
interests, obligations hereunder shall be assigned by any of the parties
hereto (whether by operation of law or otherwise) without the prior written
consent of HCI, in the event of an assignment by either member of the
Contributing Group, or Contributor, in the event of an assignment by either
member of the Newco Group. Subject to the preceding sentence, this Agreement
will be binding upon, inure to the benefit of and be enforceable by the
parties and their respective successors and assigns.
 
  10.7 Governing Law. This Agreement shall be construed, interpreted and the
rights of the parties determined in accordance with the laws of the State of
New York (without reference to the choice of law provisions), except with
respect to matters of law concerning the internal corporate affairs of any
corporate entity which is a party to or the subject of this Agreement, and as
to those matters the law of the jurisdiction under which the respective entity
derives its powers shall govern.
 
  10.8 Severability. Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part hereof to be
null, void or unenforceable, or order any party to take any action
inconsistent herewith or not to take an action consistent herewith or required
hereby, the validity, legality and enforceability of the remaining provisions
and obligations contained or set forth herein shall not in any way be
 
                                     C-25
<PAGE>
 
affected or impaired thereby, unless the foregoing inconsistent action or the
failure to take an action constitutes a material breach of this Agreement or
makes the Agreement impossible to perform, in which case this Agreement shall
terminate pursuant to Article IX. Upon any such holding that any provision of
this Agreement is null, void or unenforceable, the parties will negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that the
transactions contemplated by this Agreement are consummated to the extent
possible. Except as otherwise contemplated by this Agreement, to the extent
that a party hereto took an action inconsistent herewith or failed to take
action consistent herewith or required hereby pursuant to an order or judgment
of a court or other competent authority, such party shall incur no Liability
unless such party did not in good faith seek to resist or object to the
imposition or entering of such order or judgment.
 
  10.9 Service of Process; Consent to Jurisdiction.
 
    (a) Service of Process. Each of the parties hereto irrevocably consents
  to the service of any process, pleading, notices or other papers by the
  mailing of copies thereof by registered, certified or first class mail,
  postage prepaid, to such party at such party's address set forth herein, or
  by any other method provided or permitted under New York law. Additionally,
  each member of the Contributing Group hereby appoints Univisa, Inc., 767
  Fifth Ave., New York, N.Y. 10153 as agent for service of process in New
  York and each member of the Newco Group hereby appoints C T Corporation
  System, 1633 Broadway, New York, NY 10019 as agent for service of process
  in New York.
 
    (b) Consent and Jurisdiction. Each party irrevocably and unconditionally
  agrees and consents that any suit, action or other legal proceeding arising
  out of or related to this Agreement shall be brought and heard in the
  Borough of Manhattan, State of New York and each party irrevocably consents
  to personal jurisdiction in any and all tribunals in said Borough.
 
  10.10 Injunctive Relief. The parties acknowledge that it will be impossible
to measure in money the damages that would be suffered if the parties fail to
comply with any of the obligations herein imposed on them and that in the
event of any such failure, an aggrieved person or entity will be irreparably
damaged and will not have an adequate remedy at law. Any such person or entity
shall, therefore, be entitled to injunctive relief, including specific
performance, to enforce such obligations, and if any action should be brought
in equity to enforce any of the provisions of this Agreement, none of the
parties shall raise the defense that there is an adequate remedy at law.
 
  10.11 Arbitration. Notwithstanding anything herein to the contrary, in the
event that there shall be a dispute among the parties arising out of or
relating to Section 5.9, Article VIII or the Collateral Trust Agreement, the
parties agree that such dispute shall be resolved by final and binding
arbitration in Los Angeles, California, administered by Judicial Arbitration &
Mediation Services, Inc. ("JAMS"), in accordance with JAMS' rules of practice
then in effect or such other procedures as the parties may agree to prior to
the Closing. Depositions may be taken and other discovery may be obtained
during such arbitration proceedings to the same extent as authorized in civil
judicial proceedings. Any award issued as a result of such arbitration shall
be final and binding between the parties thereto, and shall be enforceable by
any court having jurisdiction over the party against whom enforcement is
sought. The fees and expenses of such arbitration (including reasonable
attorneys' fees) or any action to enforce an arbitration award shall be paid
by the party that does not prevail in such arbitration, unless the arbitrator
determines another method is more equitable.
 
  10.12 Attorneys' Fees. Subject to Section 10.11, if any party to this
Agreement brings an action to enforce its rights under this Agreement, the
prevailing party shall be entitled to recover its costs and expenses,
including reasonable attorneys' fees, incurred in connection with such action,
including any appeal of such action.
 
  10.13 Cumulative Remedies. All rights and remedies of each party hereto are
cumulative of each other and of every other right or remedy such party may
otherwise have at law or in equity, and the exercise of one or more rights or
remedies shall not prejudice or impair the concurrent or subsequent exercise
of other rights or remedies.

  10.14 Counterparts. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same instrument and
shall become effective when executed and delivered by each of the parties.
 
  10.15 Investment Representations.
 
    (a) Contributor is acquiring the Newco Common Stock with its own funds or
  property for investment, for its own account, and not as a nominee or agent
  for any other person, firm or corporation, and not with a view to the sale
  or distribution of all or any part thereof, and Contributor has no present
  intention of selling, granting participation in, or otherwise distributing
  any of the Newco Common Stock. Contributor does not have any contract,
  undertaking, agreement or arrangement with any person, firm or corporation
  to sell, transfer or grant participation to such person, firm or
  corporation, with respect to any of the Newco Common Stock.
 
    (b) Contributor understands and agrees that (i) the Newco Common Stock
  will not be registered under the Securities Act of 1933, as amended (the
  "Securities Act"), in part based upon an exemption from the registration
  predicated on the accuracy and completeness of its representations and
  warranties appearing herein and (ii) Contributor shall not sell, transfer
  or assign any shares of the Newco Common Stock until they are registered
  under the Act or an exemption from the registration and prospectus delivery
  requirements of the Act is available, and (iii) there is no assurance that
  such an exemption from registration will ever be available or that the
  Newco Common Stock will ever be able to be sold.
 
    (c) By reason of its net worth, Contributor is an "accredited investor"
  (as defined in Regulation D promulgated under the Securities Act).
  Contributor was not formed for the specific purpose of acquiring the stock
  issued pursuant to this Agreement. Contributor's purchase is directed by a
  sophisticated person as described in Regulation D promulgated under the
  Securities Act.
 
    (d) Contributor understands and acknowledges that each certificate
  representing the Newco Common Stock issued to Contributor in the Univisa
  Contribution will bear a legend to the following effect:
 
    "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
    REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
    SECURITIES MAY NOT BE OFFERED, SOLD, OR OTHERWISE TRANSFERRED,
    PLEDGED OR HYPOTHECATED EXCEPT PURSUANT TO (I) A REGISTRATION
    STATEMENT WITH RESPECT TO SUCH SECURITIES, WHICH IS EFFECTIVE
    UNDER SUCH ACT, OR (II) ANY EXEMPTION FROM REGISTRATION UNDER
    SUCH ACT RELATING TO THE DISPOSITION OF SECURITIES, INCLUDING
    RULE 144, PROVIDED AN OPINION OF COUNSEL IS FURNISHED,
    REASONABLY SATISFACTORY IN FORM AND SUBSTANCE TO MAGELLAN
    INTERNATIONAL, INC., THAT AN EXEMPTION FROM THE REGISTRATION
    REQUIREMENTS OF SUCH ACT IS AVAILABLE."
 
Contributor hereby agrees not to offer, sell or otherwise transfer the shares
of Newco Common Stock in violation of the foregoing legend.

and Exchange Agreement to be signed by their respective officers thereunto

Board of Directors
PanAmSat Corporation
One Pickwick Plaza
Greenwich, CT 06830
 
Members of the Board:
 
  We understand that PanAmSat Corporation ("PanAmSat" or the "Company"),
Hughes Communications, Inc. ("HCI"), Magellan International, Inc. ("Newco")
and certain other affiliates of HCI have entered into an Agreement and Plan of
Reorganization (the "Agreement") and certain related agreements, including the
Stock Contribution and Exchange Agreement (as defined below), each dated
September 20, 1996 pursuant to which Newco will acquire (a) the Galaxy
Business (as defined in the Agreement) of HCI and its affiliates by HCI
causing the contribution of the assets and liabilities comprising the Galaxy
Business, other than certain assets and liabilities, to Newco (the "Asset
Contribution") in exchange for 106,622,807 shares of common stock of Newco,
par value $0.01 per share ("Newco Common Stock"), and (b) PanAmSat by (i)
Satellite Company, L.L.C. ("S Company"), a subsidiary of Grupo Televisa, S.A.
("Televisa"), contributing all of the outstanding capital stock of Univisa,
Inc. ("Univisa"), which indirectly owns all of the shares of Class B common
stock of PanAmSat, par value $0.01 per share ("PAS Class B Common Stock"), to
Newco (the "Univisa Share Exchange") in exchange for consideration with a
deemed aggregate value equal to the product of $30.00 multiplied by the number
of shares of PAS Class B Common Stock indirectly owned by Univisa immediately
prior to the effective time of the Merger (as defined below), which
consideration will be divided into units with a deemed value of $30.00 each,
with each such unit to be exchanged at the election of S Company, subject to
proration and the Trust Holdback (as defined in the Stock Contribution and
Exchange Agreement) for (A) one share of Newco Common Stock (the "Stock
Consideration"), (B) $30.00 in cash, subject to upward adjustment if the
Closing (as defined in the Agreement) has not occurred by September 20, 1997
(the "Standard Cash Consideration") or (C) one-half share of Newco Common
Stock and one-half of the amount of the Standard Cash Consideration (the
"Standard Consideration") and (ii) a subsidiary of Newco merging with and into
PanAmSat (the "Merger", and together with the Univisa Share Exchange, the
"Transactions").
 
  At the effective time of the Merger pursuant to the terms of the Agreement,
the holder of each issued and outstanding share of common stock of PanAmSat,
par value $0.01 per share ("PAS Common Stock"), and each issued and
outstanding share of Class A common stock of PanAmSat, par value $0.01 per
share ("PAS Class A Common Stock" and, together with PAS Common Stock and PAS
Class B Common Stock, "PanAmSat Common Stock"), will have the right to elect
to receive, subject to proration, the Stock Consideration, the Standard Cash
Consideration or the Standard Consideration. The aggregate amount of cash to
be paid in the Merger and the Univisa Share Exchange will not exceed the
product obtained by multiplying one-half of the amount of the Standard Cash
Consideration by the aggregate number of shares of PanAmSat Common Stock
outstanding immediately prior to the effective time of the Merger.
 
  We also understand that, in separate but related transactions, (i)
immediately upon completion of the Transactions and the Asset Contribution and
receipt of the consideration described above, 7,500,000 shares of Newco Common
Stock received by S Company will be repurchased by Newco in exchange for
$225,000,000 in

cash (the "Share Redemption") and (ii) immediately thereafter, pursuant to the
terms of the DTH Option Purchase Agreement among PanAmSat, Televisa and S
Company dated September 20, 1996, PanAmSat will sell to Televisa, S Company or
their designee(s) its interest in the Direct-to-Home business of Televisa (the
"DTH Sale") in exchange for $225,000,000 in cash. We have not assisted in the
negotiations with respect to the Share Redemption or the DTH Sale and
understand that Salomon Brothers Inc has acted for PanAmSat in connection with
the DTH Sale and is providing an opinion to PanAmSat that the consideration to
be paid by Televisa concerning the DTH Sale represents fair value from a
financial point of view.
 
  The terms and conditions of the Asset Contribution and the Merger are more
fully set forth in the Agreement. The terms and conditions of the Univisa
Share Exchange and the Share Redemption are more fully set forth in the Stock
Contribution and Exchange Agreement (the "Stock Contribution and Exchange
Agreement") dated as of September 20, 1996 among Televisa, S Company, Newco
and HCI.
 
  On September 20, 1996, we delivered a written opinion to the Board of
Directors of PanAmSat that (i) the consideration in the aggregate to be
received by the holders of shares of PanAmSat Common Stock pursuant to the
Transactions was fair from a financial point of view to such holders and (ii)
the consideration to be paid in the Share Redemption is fair from a financial
point of view to Newco, and you have now asked us to reconfirm our earlier
opinion.
 
  For purposes of the opinion set forth herein, we have:
 
  (i) analyzed certain publicly available financial statements of PanAmSat
      and other publicly available information relating to PanAmSat and the
      Galaxy Business;
 
  (ii) analyzed certain internal financial statements and other financial and
       operating data concerning PanAmSat and the Galaxy Business prepared by
       the respective managements of PanAmSat and HCI and discussed certain
       of this data with senior executives of PanAmSat and HCI;
 
  (iii) analyzed certain financial projections of PanAmSat and the Galaxy
        Business prepared by the respective managements of PanAmSat and HCI;
 
  (iv) discussed the past and current operations and financial condition and
       the prospects of PanAmSat and the Galaxy Business with senior
       executives of PanAmSat and HCI, respectively;
 
  (v) reviewed the reported prices and trading activity for PanAmSat Common
      Stock;
 
  (vi) analyzed the estimated pro forma impact of the Transactions and the
       Asset Contribution on Newco's financial ratios;
 
  (vii) reviewed and considered the financial and other information prepared
        by members of senior management of PanAmSat and HCI relating to the
        relative contributions of PanAmSat and the Galaxy Business to the
        combined company;
 
  (viii) participated in discussions and negotiations among representatives
         of PanAmSat, HCI and certain other parties and their financial and
         legal advisors;
 
  (ix) reviewed the Agreement, the Stock Contribution and Exchange Agreement
       and certain related documents; and
 
  (x) performed such other analyses as we have deemed appropriate.
 
  We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes
of this opinion. With respect to the financial projections, we have assumed
that they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the future financial performance of
PanAmSat and the Galaxy Business, respectively. We have not made any
independent valuation or appraisal of the assets or liabilities of PanAmSat or
the Galaxy Business, nor have we been furnished with any such appraisals. We
have assumed that the Transactions, the Asset Contribution and the Share
Redemption will be consummated in accordance with the terms set forth in the
Agreement, the
 
                                      D-2

                                            [Letterhead of Morgan Stanley & Co.]
 
Stock Contribution and Exchange Agreement and certain related agreements. Our
opinion is necessarily based on economic, market and other conditions as in
effect on, and the information made available to us as of, the date hereof. We
have assumed that the Transactions and the Asset Contribution together will be
treated as a tax-free exchange, pursuant to the Internal Revenue Code of 1986,
as amended. We have also assumed that in connection with the receipt of all
necessary regulatory approvals for the Transactions and the Asset
Contribution, no restrictions will be imposed that would have a material
adverse effect on the contemplated benefits expected to be derived in the
proposed Transactions and the Asset Contribution.
 
  We have acted as financial advisor to the Board of Directors of PanAmSat in
connection with the Transactions and will receive a fee for our services. In
the past, Morgan Stanley & Co. Incorporated ("Morgan Stanley") and its
affiliates have provided financial advisory and financing services for
PanAmSat, Televisa and HCI and certain of their affiliates and have received
fees for the rendering of these services. As part of such services, Morgan
Stanley acted as lead underwriter in connection with the initial public
offering of PAS Common Stock in September 1995. In addition, concurrent with
the negotiation of the Transactions and the Asset Contribution and at the
request of Televisa, certain principal investing funds affiliated with Morgan
Stanley have been in preliminary discussions with Televisa concerning the
potential acquisition or financing of some or all of the Newco Common Stock
from Televisa and/or certain of its affiliates.
 
  We express no opinion and make no recommendation as to whether the holders
of PanAmSat Common Stock should elect to receive the Standard Consideration,
the Stock Consideration or the Standard Cash Consideration.
 
  It is understood that this letter is for the information of the Board of
Directors of PanAmSat and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its
entirety in any filing made by PanAmSat in respect of the Transactions with
the Securities and Exchange Commission. In addition, this opinion does not in
any manner address the prices at which the shares of Newco Common Stock will
trade following consummation of the Transactions, the Asset Contribution and
the Share Redemption, and Morgan Stanley expresses no opinion or
recommendation as to how the stockholders of PanAmSat Common Stock should vote
at the stockholders' meeting held in connection with the Transactions.
 
  Based on the foregoing, we are of the opinion on the date hereof that (i)
the consideration in the aggregate to be received by the holders of shares of
PanAmSat Common Stock pursuant to the Transactions is fair from a financial
point of view to such holders and (ii) the consideration to be paid in the
Share Redemption is fair from a financial point of view to Newco.
 
                                          Very truly yours,

  Members of the Board:

    You have advised us that Grupo Televisa, S.A. or one of its affiliates
  ("Televisa") will pay $225,000,000 in cash to PanAmSat Corporation (the
  "Company") to acquire the Company's options (the "Options") to purchase
  49%, 15%, 12%, 14% and 10% of certain direct-to-home satellite television
  broadcasting businesses (collectively, the "Business") conducted by
  Televisa and other entities in Spain, Mexico, the United States, South
  America (excluding Argentina, Brazil and Chile) and Argentina and Chile,
  respectively. You have requested our opinion as to the fairness to the
  Company of the consideration to be paid by Televisa to acquire the
  Options. The purchase of the Options will be made in connection with the
  combination (the "Merger") of the Company with certain businesses owned by
  Hughes Electronics Corporation ("Hughes").
 
    In connection with rendering our opinion, we have reviewed certain
  publicly available information concerning the Company and certain other
  financial information concerning the Company and the Business, including
  financial forecasts, that were provided to us by the Company. We have
  discussed the business operations and financial condition of the Business,
  as well as other matters we believe relevant to our inquiry, with certain
  officers and employees of the Company, Televisa and the Business. We also
  considered such other information, financial studies, analyses,
  investigations and financial, economic and market criteria that we deemed
  relevant.
 
    In our review and analysis and in arriving at our opinion, we have
  assumed and relied upon the accuracy and completeness of the financial and
  other information reviewed by us, and we have not assumed any
  responsibility for independent verification of such information. With
  respect to the financial forecasts of the Business, we have assumed that
  they have been reasonably prepared on bases reflecting the best currently
  available estimates and judgments of the management of the Business as to
  the future financial performance of the Business, and we express no
  opinion with respect to such forecasts or the assumptions on which they
  are based. We have not made or obtained or assumed any responsibility for
  making or obtaining any independent evaluations or appraisals of any of
  the assets (including properties and facilities) or liabilities of the
  Business. We were not asked to, and did not, solicit other proposals for
  the acquisition of the Options.

   Our opinion is necessarily based upon conditions as they exist and can be
 evaluated on the date hereof. Our opinion does not address the Company's
 underlying business decision to sell the Options to Televisa in connection
 with the Merger. Our opinion does not address the fairness of the Merger.
 Our opinion is directed only to the consideration to be paid by Televisa to
 acquire the Options and does not constitute a recommendation concerning how
 any holder of the Company's securities should vote with respect to the
 Merger.
 
   We have acted as financial advisor to the Company and will receive a fee
 for our services, a portion of which is payable upon delivery of this
 opinion and a portion of which is conditioned upon consummation of a sale by
 the Company of the Options. In the ordinary course of business, we may
 actively trade the securities of the Company, Televisa and Hughes for our
 own account and for the accounts of customers and, accordingly, may at any
 time hold a long or short position in such securities.
 
   Based upon and subject to the foregoing, it is our opinion that, as of the
 date hereof, the consideration to be paid by Televisa to acquire the Options
 represents fair value for the Options from a financial point of view.
 
                                         Very truly yours,

  SECTION 7.1. Right to Indemnification. The Corporation shall indemnify and
hold harmless, to the fullest extent permitted by applicable law as it
presently exists or may hereafter be amended, any person who was or is made or
is threatened to be made a party or is otherwise involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative (a
"proceeding") by reason of the fact that he, or a person for whom he is the
legal representative, is or was a director or officer of the Corporation or is
or was serving at the request of the Corporation as a director, officer,
employee or agent of another Corporation or of a partnership, joint venture,
trust, enterprise or nonprofit entity, including service with respect to
employee benefit plans, against all liability and loss suffered and expenses
(including attorneys' fees) incurred by such person. Except as provided in
Section 7.3, the Corporation shall not be required to indemnify a person in
connection with a proceeding (or part thereof) initiated by such person unless
the proceeding (or part thereof) was authorized by the Board of Directors of
the Corporation.
 
  SECTION 7.2. Advancement of Expenses. The Corporation shall pay the expenses
(including attorneys' fees) of any person referred to in Section 7.1 of this

disposition; provided, however, that the advancement of expenses incurred by a
director or officer in advance of the final disposition of the proceeding

to repay all amounts advanced if it should be ultimately determined that the
director or officer is not entitled to be indemnified under this ARTICLE SEVEN
or otherwise.
 
  SECTION 7.3. Claims. If a claim for indemnification or advancement of
expenses under this ARTICLE SEVEN is not paid in full within sixty (60) days

the case of a claim for advancement of expenses, in which case the applicable
period shall be twenty (20) days), the claimant may file suit to recover the
unpaid amount of such claim. If successful in whole in such an action, the
claimant shall be entitled to be paid the expense of prosecuting such claim;
if successful in part in such an action, the claimant shall be entitled to be
paid the expense of prosecuting each successfully resolved claim, issue or
matter. In any such action the Corporation shall have the burden of proving
that the claimant was not entitled to the requested indemnification or
advancement of expenses under applicable law.
 
  SECTION 7.4. Non-Exclusivity of Rights. The rights conferred on any person
by this ARTICLE SEVEN shall not be exclusive of any other rights which such
person may have or hereafter acquire under any statute, provision of this
Restated Certificate of Incorporation, provision of the bylaws, agreement,

indemnify any person who was or is serving at its request as a director,

person would be entitled to retain as indemnification from such other
corporation, partnership, joint venture, trust, enterprise or nonprofit
enterprise.

                                   ARTICLE I
 
                                 STOCKHOLDERS
 
  SECTION 1.1. Annual Meetings. An annual meeting of stockholders shall be
held for the election of directors at such date, time and place, either within
or without the State of Delaware, as may be designated by resolution of the
Board of Directors from time to time. Any other proper business may be
transacted at the annual meeting.
 
  SECTION 1.2. Special Meetings. Special meetings of stockholders for any
purpose or purposes may be called at any time by the Board of Directors, or by
a committee of the Board of Directors that has been duly designated by the
Board of Directors and whose powers and authority, as provided in a resolution
of the Board of Directors, include the power to call such meetings, but such
special meetings may not be called by any other person or persons.
 
  SECTION 1.3. Notice of Meetings. Whenever stockholders are required or
permitted to take any action at a meeting, a written notice of the meeting
shall be given that shall state the place, date and hour of the meeting and,
in the case of a special meeting, the purpose or purposes for which the
meeting is called. Unless otherwise provided by law, the certificate of
incorporation or these Bylaws, the written notice of any meeting shall be
given not less than ten (10) nor more than sixty (60) days before the date of
the meeting to each stockholder entitled to vote at such meeting. If mailed,
such notice shall be deemed to be given when deposited in the United States
mail, postage prepaid, directed to the stockholder at his address as it
appears on the records of the Corporation.
 
  SECTION 1.4. Adjournments. Any meeting of stockholders, annual or special,
may adjourn from time to time to reconvene at the same or some other place,
and notice need not be given of any such adjourned meeting if the time and
place thereof are announced at the meeting at which the adjournment is taken.
At the adjourned meeting the Corporation may transact any business which might
have been transacted at the original meeting. If the adjournment is for more
than thirty (30) days, or if after the adjournment a new record date is fixed
for the adjourned meeting, notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the meeting.
 
  SECTION 1.5. Quorum. Except as otherwise provided by law, the certificate of
incorporation or these Bylaws, at each meeting of stockholders the presence in
person or by proxy of the holders of shares of stock having a majority of the
votes which could be cast by the holders of all outstanding shares of stock
entitled to vote at the meeting shall be necessary and sufficient to
constitute a quorum. Where a separate vote by a series, class or classes is
required, a majority of the outstanding shares of stock of such class or
classes on any particular issue, present in person or represented by proxy,
shall be necessary and sufficient to constitute a quorum for purposes of such
issue. In the absence of a quorum, the stockholders so present may, by
majority vote, adjourn the meeting from time to time in the manner provided in
Section 1.4 of these Bylaws until a quorum shall attend. Shares of its own
stock belonging to the Corporation or to another corporation, if a majority of
the shares entitled to vote in the election of directors of such other
corporation is held, directly or indirectly, by the Corporation, shall neither
be entitled to vote nor be counted for quorum purposes; provided, however,
that the foregoing shall not limit the right of the Corporation to vote stock,
including but not limited to its own stock, held by it in a fiduciary
capacity.
 
  SECTION 1.6. Organization. Meetings of stockholders shall be presided over
by the Chairman of the Board, if any, or in his absence by the President, or
in his absence by an Executive Vice President, or in the
 
                                      G-1
<PAGE>
 
absence of the foregoing persons by a chairman designated by the Board of
Directors, or in the absence of such designation by a chairman chosen at the
meeting. The Secretary shall act as secretary of the meeting, but in his
absence the chairman of the meeting may appoint any person to act as secretary
of the meeting. The chairman of the meeting shall announce at the meeting of
stockholders the date and time of the opening and the closing of the polls for
each matter upon which the stockholders will vote.
 
  SECTION 1.7. Voting; Proxies. Each stockholder entitled to vote at any
meeting of stockholders shall be entitled to one vote for each share of stock
held by such stockholder which has voting power upon the matter in question.
At all meetings of stockholders for the election of directors, a plurality of
the votes cast shall be sufficient to elect a director. All other elections
and questions shall, unless otherwise provided by law, the certificate of
incorporation, these Bylaws or the rules or regulations of any stock exchange
applicable to the Corporation, be decided by the affirmative vote of the
holders of shares of stock having a majority of the votes present in person or
represented by proxy and entitled to vote thereon. Each stockholder entitled
to vote at a meeting of stockholders may authorize another person or persons
to act for him by proxy, but no such proxy shall be voted or acted upon after
three years from its date, unless the proxy provides for a longer period. A
proxy shall be irrevocable if it states that it is irrevocable and if, and
only as long as, it is coupled with an interest sufficient in law to support
an irrevocable power. A stockholder may revoke any proxy which is not
irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the proxy or by delivering a proxy in
accordance with applicable law bearing a later date to the Secretary of the
Corporation. Voting at meetings of stockholders need not be by written ballot.
 
  SECTION 1.8. Fixing Date for Determination of Stockholders of Record. In
order that the Corporation may determine the stockholders entitled to notice
of or to vote at any meeting of stockholders or any adjournment thereof, or
entitled to receive payment of any dividend or other distribution or allotment
of any rights, or entitled to exercise any rights in respect of any change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted
by the Board of Directors and which record date: (i) in the case of
determination of stockholders entitled to vote at any meeting of stockholders
or adjournment thereof, shall, unless otherwise required by law, not be more
than sixty nor less than ten (10) days before the date of such meeting; and
(ii) in the case of any other action, shall not be more than sixty (60) days
prior to such other action. If no record date is fixed: (i) the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the day next preceding the
day on which notice is given, or, if notice is waived, at the close of
business on the day next preceding the day on which the meeting is held; and
(ii) the record date for determining stockholders for any other purpose shall
be at the close of business on the day on which the Board of Directors adopts
the resolution relating thereto. A determination of stockholders of record
entitled to notice of or to vote at a meeting of stockholders shall apply to
any adjournment of the meeting; provided, however, that the Board of Directors
may fix a new record date for the adjourned meeting.
 
  SECTION 1.9. List of Stockholders Entitled to Vote. The Secretary shall
prepare and make, at least ten (10) days before every meeting of stockholders,
a complete list of the stockholders entitled to vote at the meeting, arranged
in alphabetical order, and showing the address of each stockholder and the
number of shares registered in the name of each stockholder. Such list shall
be open to the examination of any stockholder, for any purpose germane to the
meeting, during ordinary business hours, for a period of at least ten (10)
days prior to the meeting, either at a place within the city where the meeting
is to be held, which place shall be specified in the notice of the meeting, or
if not so specified, at the place where the meeting is to be held. The list
shall also be produced and kept at the time and place of the meeting during
the whole time thereof and may be inspected by any stockholder who is present.
 
  SECTION 1.10. Stock Ledger. The stock ledger of the Corporation shall be the
only evidence as to who are the stockholders entitled to examine the stock
ledger, the list required by Section 1.9 of this ARTICLE I, or to vote in
person or by proxy at any meeting of stockholders.
 
                                      G-2

  SECTION 1.11. Conduct of Meetings. The Board of Directors of the Corporation
may adopt by resolution such rules and regulations for the conduct of the
meeting of stockholders as it shall deem appropriate. Except to the extent
inconsistent with such rules and regulations as adopted by the Board of
Directors, the chairman of any meeting of stockholders shall have the right
and authority to prescribe such rules, regulations and procedures and to do
all such acts as, in the judgment of such chairman, are appropriate for the
proper conduct of the meeting. Such rules, regulations or procedures, whether
adopted by the Board of Directors or prescribed by the chairman of the
meeting, may include, without limitation, the following: (i) the establishment
of an agenda or order of business for the meeting; (ii) rules and procedures
for maintaining order at the meeting and the safety of those present; (iii)
limitations on attendance at or participation in the meeting to stockholders
of record of the Corporation, their duly authorized and constituted proxies or
such other persons as the chairman of the meeting shall determine; (iv)
restrictions on entry to the meeting after the time fixed for the commencement
thereof; and (v) limitations on the time allotted to questions or comments by
participants. Unless and to the extent otherwise determined by the Board of
Directors or the chairman of the meeting, meetings of stockholders shall not
be required to be held in accordance with the rules of parliamentary
procedure.
 
  SECTION 1.12. Advance Notice of Stockholder Nominations and Business.
 
  (A) Annual Meetings of Stockholders.
 
    (1) Nominations of persons for election to the Board of Directors and the
  proposal of business to be considered by the stockholders may be made at an
  annual meeting of stockholders (a) pursuant to the Corporation's notice of
  meeting, (b) by or at the direction of the Board of Directors or (c) by any
  stockholder of the Corporation who was a stockholder of record at the time
  of giving of notice provided for in this Bylaw, who is entitled to vote at
  the meeting and complies with the notice procedures set forth in this
  Bylaw.
 
    (2) For nominations or other business to be properly brought before an
  annual meeting by a stockholder pursuant to clause (c) of paragraph (A)(1)
  of this Bylaw, the stockholder must have given timely notice thereof in
  writing to the Secretary of the Corporation and such other business must
  otherwise be a proper matter for stockholder action. To be timely, a
  stockholder's notice shall be delivered to the Secretary at the principal
  executive offices of the Corporation not later than the close of business
  on the 60th day nor earlier than the close of business on the 90th day
  prior to the first anniversary of the preceding year's annual meeting;
  provided, however, that in the event that the date of the annual meeting is
  more than thirty (30) days before or more than sixty (60) days after such
  anniversary date, notice by the stockholder to be timely must be so
  delivered not earlier than the close of business on the 90th day prior to
  such annual meeting and not later than the close of business on the later
  of the 60th day prior to such annual meeting or the 10th day following the
  day on which public announcement of the date of such meeting is first made
  by the Corporation. In no event shall the public announcement of an
  adjournment of an annual meeting commence a new time period for the giving
  of a stockholder's notice as described above. Such stockholder's notice
  shall set forth (a) as to each person whom the stockholder proposes to
  nominate for election or re-election as a director all information relating
  to such person that is required to be disclosed in solicitations of proxies
  for election of directors in an election contest, or is otherwise required,
  in each case pursuant to Regulation 14A under the Securities Exchange Act
  of 1934, as amended (the "Exchange Act") and Rule 14a-11 thereunder
  (including such person's written consent to being named in the proxy
  statement as a nominee and to serving as a director if elected); (b) as to
  any other business that the stockholder proposes to bring before the
  meeting, a brief description of the business desired to be brought before
  the meeting, the reasons for conducting such business at the meeting and
  any material interest in such business of such stockholder and the
  beneficial owner, if any, on whose behalf the proposal is made; and (c) as
  to the stockholder giving the notice and the beneficial owner, if any, on
  whose behalf the nomination or proposal is made (i) the name and address of
  such stockholder, as they appear on the Corporation's books, and of such
  beneficial owner, (ii) the class and number of shares of the Corporation
  which are owned beneficially and of record by such stockholder and such
  beneficial owner, and (iii) whether the proponent intends or is part of a
  group which intends to solicit proxies from other stockholders in support
  of such proposal or nomination.
 
                                      G-3
<PAGE>
 
    (3) Notwithstanding anything in the second sentence of paragraph (A)(2)
  of this Bylaw to the contrary, in the event that the number of directors to
  be elected to the Board of Directors of the Corporation is increased and
  there is no public announcement by the Corporation naming all of the
  nominees for director or specifying the size of the increased Board of
  Directors at least seventy (70) days prior to the first anniversary of the
  preceding year's annual meeting, a stockholder's notice required by this
  Bylaw shall also be considered timely, but only with respect to nominees
  for any new positions created by such increase, if it shall be delivered to
  the Secretary at the principal executive offices of the Corporation not
  later than the close of business on the 10th day following the day on which
  such public announcement is first made by the Corporation.
 
  (B) Special Meetings of Stockholders. Only such business shall be conducted
at a special meeting of stockholders as shall have been brought before the
meeting pursuant to the Corporation's notice of meeting. Nominations of
persons for election to the Board of Directors may be made at a special
meeting of stockholders at which directors are to be elected pursuant to the
Corporation's notice of meeting (a) by or at the direction of the Board of
Directors or (b) provided that the Board of Directors has determined that
directors shall be elected at such meeting, by any stockholder of the
Corporation who is a stockholder of record at the time of giving of notice
provided for in this Bylaw, who shall be entitled to vote at the meeting and
who complies with the notice procedures set forth in this Bylaw. In the event
the Corporation calls a special meeting of stockholders for the purpose of
electing one or more directors to the Board of Directors, any such stockholder
may nominate a person or persons (as the case may be) for election to such
position(s) as specified in the Corporation's notice of meeting, if the
stockholder's notice required by paragraph (A)(2) of this Bylaw shall be
delivered to the Secretary at the principal executive offices of the
Corporation not earlier than the close of business on the 90th day prior to
such special meeting and not later than the close of business on the later of
the 60th day prior to such special meeting, or the 10th day following the day
on which public announcement is first made of the date of the special meeting
and of the nominees proposed by the Board of Directors to be elected at such
meeting. In no event shall the public announcement of an adjournment of a
special meeting commence a new time period for the giving of a stockholder's
notice as described above.
 
  (C) General.
 
    (1) Only such persons who are nominated in accordance with the procedures
  set forth in this Bylaw shall be eligible to serve as directors and only
  such business shall be conducted at a meeting of stockholders as shall have
  been brought before the meeting in accordance with the procedures set forth
  in this Bylaw. Except as otherwise provided by law, the certificate of
  incorporation or these Bylaws, the chairman of the meeting shall have the
  power and duty to determine whether a nomination or any business proposed
  to be brought before the meeting was made or proposed, as the case may be,
  in accordance with the procedures set forth in this Bylaw and, if any
  proposed nomination or business is not in compliance with this Bylaw, to
  declare that such defective proposal or nomination shall be disregarded.
 
    (2) For purposes of this Bylaw, "public announcement" shall mean
  disclosure in a press release reported by the Dow Jones News Service,
  Associated Press or comparable national news service or in a document

                       DELAWARE GENERAL CORPORATION LAW
 
  SECTION 262 APPRAISAL RIGHTS.--(a) Any stockholder of a corporation of this
State who holds shares of stock on the date of the making of a demand pursuant
to subsection (d) of this section with respect to such shares, who
continuously holds such shares through the effective date of the merger or
consolidation, who has otherwise complied with subsection (d) of this section
and who has neither voted in favor of the merger or consolidation nor
consented thereto in writing pursuant to (S) 228 of this title shall be
entitled to an appraisal by the Court of Chancery of the fair value of his
shares of stock under the circumstances described in subsections (b) and (c)
of this section. As used in this section, the word "stockholder" means a
holder of record of stock in a stock corporation and also a member of record
of a nonstock corporation; the words "stock" and "share" mean and include what
is ordinarily meant by those words and also membership or membership interest
of a member of a nonstock corporation; and the words "depository receipt" mean
a receipt or other instrument issued by a depository representing an interest
in one or more shares, or fractions thereof, solely of stock of a corporation,
which stock is deposited with the depository.
 
  (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to
be effected pursuant to (S) 251 (other than a merger effected pursuant to
subsection (g) of Section 251), 252, 254, 257, 258, 263 or 264 of this title:
 
    (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or (ii) held
  of record by more than 2,000 holders; and further provided that no
  appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the holders of the surviving corporation as
  provided in subsection (f) of (S) 251 of this title.
 
    (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series
  of stock of a constituent corporation if the holders thereof are required
  by the terms of an agreement of merger or consolidation pursuant to (S)(S)
  251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock
  anything except:
 
      a. Shares of stock of the corporation surviving or resulting from
    such merger or consolidation, or depository receipts in respect
    thereof;
 
      b. Shares of stock of any other corporation, or depository receipts
    in respect thereof, which shares of stock or depository receipts at the
    effective date of the merger or consolidation will be either listed on
    a national securities exchange or designated as a national market
    system security on an interdealer quotation system by the National
    Association of Securities Dealers, Inc. or held of record by more than
    2,000 holders;
 
      c. Cash in lieu of fractional shares or fractional depository
    receipts described in the foregoing subparagraphs a. and b. of this
    paragraph; or
 
      d. Any combination of the shares of stock, depository receipts and
    cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a., b. and c. of this
    paragraph.
 
    (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under (S) 253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall
  be available for the shares of the subsidiary Delaware corporation.
 
  (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all
 
                                      I-1
<PAGE>
 
or substantially all of the assets of the corporation. If the certificate of
incorporation contains such a provision, the procedures of this section,
including those set forth in subsections (d) and (e) of this section, shall
apply as nearly as is practicable.
 
  (d) Appraisal rights shall be perfected as follows:
 
    (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsections (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of his shares shall deliver to the
  corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of his shares. A proxy or vote against the merger or
  consolidation shall not constitute such a demand. A stockholder electing to
  take such action must do so by a separate written demand as herein
  provided. Within 10 days after the effective date of such merger or
  consolidation, the surviving or resulting corporation shall notify each
  stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or
 
    (2) If the merger or consolidation was approved pursuant to (S) 228 or
  (S) 253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholders
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within twenty days after the date of
  mailing of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that if such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given; provided that,
  if the notice is given on or after the effective date of the merger or
  consolidation, the record date shall be such effective date. If no record
  date is fixed and the notice is given prior to the effective date, the
  record date shall be the close of business on the day next preceding the
  day on which the notice is given.
 
  (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied
with subsections (a) and (d) hereof and who is otherwise
 
                                      I-2
<PAGE>
 
entitled to appraisal rights, may file a petition in the Court of Chancery
demanding a determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the
merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting
from the consolidation a statement setting forth the aggregate number of
shares not voted in favor of the merger or consolidation and with respect to
which demands for appraisal have been received and the aggregate number of
holders of such shares. Such written statement shall be mailed to the
stockholder within 10 days after his written request for such a statement is
received by the surviving or resulting corporation or within 10 days after
expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.
 
  (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
  (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates
to submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
  (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court
may, in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on
the list filed by the surviving or resulting corporation pursuant to
subsection (f) of this section and who has submitted his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to
appraisal rights under this section.
 
  (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Court's decree may be enforced
as other decrees in the Court of Chancery may be enforced, whether such
surviving or resulting corporation be a corporation of this State or of any
state.
 
                                      I-3
<PAGE>
 
  (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
  (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal
of his demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.
 
  (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation. (Last amended by Ch. 349, L.
'96, eff. 7-1-96.)

      a pledgee pursuant to a bona fide pledge of such shares as
      collateral security for indebtedness due to the pledgee, provided
      that such shares may not be transferred to or registered in the name
      of the pledgee unless such pledgee is a Permitted Transferee. In the
      event of foreclosure or other similar action by a pledgee who is not
      a Permitted Transferee, such pledged shares of Class A Common Stock
      or Class B Common Stock shall convert automatically, without any act
      or deed on the part of the Corporation or any other person, into
      shares of Common Stock as provided in this Paragraph 5.8, unless
      within five business days after such foreclosure or similar event
      such converted shares are returned to the pledgor or transferred to
      a Permitted Transferee.
 
  ARTICLE FIVE, paragraph 5.10 is restated in its entirety to read as
  follows:
 
        5.10. Consideration on Merger, Consolidation, etc. In any merger,
      consolidation, or business combination, the consideration to be
      received per share by the holders of Class A Common Stock, Class B
      Common Stock and Common Stock must be identical for each class of
      stock, except that in any such transaction in which shares of common
      equity are to be distributed, such shares may differ as to voting
      rights to the extent that voting rights differ among the Class A
      Common Stock, the Class B Common Stock and the Common Stock as
      provided in this Amended and Restated Certificate of Incorporation;
      provided, however, that neither this Paragraph 5.10 nor any other
      provision of this ARTICLE FIVE shall in any way limit, prevent or
      restrict the Corporation from entering into, consummating or
      performing, or otherwise apply to, the transactions contemplated by
      the Stock Contribution and Exchange Agreement, the Reorganization
      Agreement or the Merger Agreement and the agreements related
      thereto, including the consummation of the merger of Merger Sub into
      the Corporation contemplated thereby.

                              ASSURANCE AGREEMENT
 
  This ASSURANCE AGREEMENT (this "Agreement"), dated September 20, 1996, is
entered into by and between HUGHES ELECTRONICS CORPORATION, a Delaware
corporation ("HE"), PANAMSAT CORPORATION, a Delaware corporation ("PAS"),
SATELLITE COMPANY, LLC, a Nevada limited liability company ("S Company") and
MAGELLAN INTERNATIONAL, INC., a Delaware corporation ("Newco").
 
                                   RECITALS
 
  A. Concurrently with the execution and delivery hereof, (i) PAS is entering
into an Agreement and Plan of Reorganization (the "Reorganization Agreement")
with Hughes Communications, Inc., a California corporation ("HCI"), Hughes
Communications Galaxy, Inc., a California corporation ("Galaxy"), Hughes
Communications Satellite Services, Inc., a California corporation ("HCSS"),
Hughes Communications Services, Inc., a California corporation ("HCS"), Hughes
Communications Carrier Services, Inc., a California corporation ("HCCS"),
Hughes Communications Japan, Inc., a California corporation ("HCJ"), and
Newco, and (ii) S Company is entering into a share exchange agreement (the
"Univisa Contribution Agreement") with Newco, pursuant to which agreements
Newco will acquire (i) the existing businesses of certain subsidiaries of HCI
that together comprise the Galaxy Business (as defined in the Reorganization
Agreement) and (ii) the business of PAS.
 
  B. As a condition and inducement to PAS to enter into the Reorganization
Agreement (and effect the transactions contemplated thereby) and S Company to
enter into the Univisa Contribution Agreement (and effect the transactions
contemplated thereby) HE has agreed to enter into this Agreement and perform
its obligations contemplated hereby.
 
  C. Capitalized terms used herein and not otherwise defined herein shall have
the meanings set forth in the Reorganization Agreement.
 
                                   AGREEMENT
 
  In consideration of the foregoing and the mutual promises contained herein
and in the Reorganization Agreement and for other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties hereto, intending to be legally bound, hereby agree as follows:
 
  1. Provision or Arrangement of Financing. On or before the Closing Date, HE
will loan or arrange for one or more persons or entities that are not
affiliated with either PAS or HE (each such person or entity, an "Unaffiliated
Person") to loan to Newco and/or to one or more Subsidiaries of Newco (other
than PAS, Univisa, Merger Sub or any of their respective direct or indirect
Subsidiaries) one billion seven hundred twenty-five million dollars
($1,725,000,000), plus interest required under the Reorganization Agreement,
which loan shall be funded on the Closing Date or as needed by Newco to pay
the cash required by Newco to consummate the Univisa Contribution (including
Newco's repurchase of shares of Newco Common Stock contemplated thereby) and
the Merger; provided, however, that (i) HE's obligation to make or arrange any
such loan or loans shall be conditioned upon satisfaction of all conditions to
Closing contained in Sections 8.1 and 8.3 of the Reorganization Agreement; and
(ii) if any such loan or loans are provided by an Unaffiliated Person, HE
shall not be obligated to provide any form of guarantee or other credit
enhancement in support of any such loan or loans provided by one or more
Unaffiliated Persons. In the event HE makes any such loan or loans to Newco,
the terms of such loan or loans shall be commercially reasonable as determined
by Chase Manhattan Bank, Bank of America NT&SA and a third bank, if necessary
to decide matters upon which such banks have failed to agree, chosen by such
two banking institutions.

  2. Contribution of Galaxy Business. Subject to the terms and conditions set
forth in the Reorganization Agreement, HE shall cause its Subsidiaries to take
all actions necessary for Newco to own, upon consummation of the transactions
contemplated by the Reorganization Agreement, all right, title and interest in
and to the assets necessary to conduct the Galaxy Business, together with the
Galaxy Liabilities. HE represents and warrants that (i) the Galaxy Employees
are all of the employees who work primarily in the Galaxy Business, (ii) the
Galaxy Assets are all of the assets used in the Galaxy Business and (iii) the
Galaxy Business is conducted entirely through and by HCI and its subsidiaries,
Galaxy, HCSS, HCS, HCCS and HCJ.
 
  3. Operation of Galaxy Business in Ordinary Course. Subject to the terms and
conditions set forth in the Reorganization Agreement, HE shall cause its
Subsidiaries to continue to operate the Galaxy Business in a manner consistent
with the operation of the Galaxy Business prior to the date hereof.
 
  4. Performance Obligations. Subject to the terms and conditions set forth in
the Reorganization Agreement, HE shall cause its Subsidiaries, including HCI,
Galaxy, HCSS, HCS, HCCS, HCJ and Newco, to perform their respective
obligations under the Reorganization Agreement and the Related Agreements.
Within 45 days after the Closing Date, Newco shall provide HE with a
reasonably detailed statement regarding compliance by HCI and its Affiliates
with the funding requirements of the Reorganization Agreement, which statement
shall be accompanied by a request for payment of any funding deficiency or an
acknowledgment of any reimbursement of any overfunding that is owed. Promptly
following the giving of such notice, HE or Newco, as the case may be, shall
make the payment set forth in such notice. Without limiting the foregoing, HE
agrees that where in the Reorganization Agreement or the Related Agreements it
is stated that HE or its Affiliates will take or refrain from taking certain
actions, HE will, or will cause its relevant Affiliate to, take or refrain
from taking such action, as required by the pertinent provision.
 
  5. Leveraged Lease Guaranty. Subsequent to the Closing Date, HE shall
continue to guaranty leveraged leases of transponders used in the Galaxy
Business entered into prior to the date of this Agreement.
 
  6. Cross License of Intellectual Property. Prior to the Closing, HE shall,
and shall cause its Subsidiaries to, enter into negotiations with
representatives of PAS with the intent of executing and delivering at Closing
a non-exclusive, royalty-free, perpetual Cross License Agreement, with
standard terms and conditions mutually acceptable to HCI and PAS, whereby
Newco shall have the right to use any HE Licensed Intellectual Property that
was used in the Galaxy Business on or before the Closing and HE shall have the
right to use any Galaxy Licensed Intellectual Property that was used in the
Hughes Electronics businesses on or before the Closing. As used in this
Agreement, the phrase "HE Licensed Intellectual Property" shall refer to all
domestic, foreign, common law, registered and pending applications for
patents, copyrights, trade secrets, know-how, confidential information,
computer programs (including any source code), documentation, engineering and
technical drawings, processes, methodologies, and technology (excluding any
Intellectual Property owned and developed by Galaxy) of HE and its Affiliates
that was used in the Galaxy Business on or before Closing. As used in this
Agreement, the phrase "Galaxy Licensed Intellectual Property" shall mean all
Newco owned domestic, foreign, common law, registered and pending applications
for patents, copyrights, trade secrets, know-how, confidential information,
computer programs (including any source code), documentation, engineering and
technical drawings, processes, methodologies, and technology that are conveyed
to Newco pursuant to Section 1.1 of the Reorganization Agreement.
 
  7. Miscellaneous.
 
    (a) Termination. This Agreement and all obligations contained hereunder
  shall terminate upon the date on which the Reorganization Agreement is
  terminated; provided that HE shall remain liable for its obligations
  hereunder if the termination of the Reorganization Agreement is pursuant to

    (b) Expenses. All costs and expenses incurred in connection with this
  Agreement and transactions contemplated hereby shall be paid by the party
  incurring such expenses.

    (c) Interpretation. Headings contained in this Agreement are for
  reference purposes only and shall not affect in any way the meaning or
  interpretation of this Agreement. Whenever the word "include," "includes"
  or "including" are used in this Agreement, they shall be deemed to be
  followed by the words "without limitation." This Agreement shall not be
  construed for or against either party by reason of the authorship or
  alleged authorship of any provision hereof or by reason of the status of
  the respective parties.
 
    (d) Entire Agreement; No Third-Party Beneficiaries. This Agreement
  constitutes the entire agreement and supersedes all prior agreements and
  understandings, both written and oral, among the parties with respect to
  the subject matter hereof and is not intended to confer upon any person
  other than the parties hereto any rights or remedies hereunder.
 
    (e) Assignment. Neither this Agreement nor any of the rights, interests
  or obligations hereunder shall be assigned by any of the parties hereto
  whether by operation of law or otherwise without the prior written consent
  of the other parties. Subject to the preceding sentence, this Agreement
  will be binding upon and for the benefit of and be enforceable by the
  parties and their respective successors and assigns.
 
    (f) Governing Law. This Agreement shall be construed, interpreted and the
  rights of the parties determined in accordance with the laws of the State
  of Delaware (without reference to the choice of law provisions), except
  with respect to matters of law concerning the internal corporate affairs of
  any corporate entity which is a party to or the subject of this Agreement,
  and as to those matters the law of the jurisdiction under which the
  respective entity derives its powers shall govern.
 
    (g) Severability. Each party agrees that, should any court or other
  competent authority hold any provision of this Agreement or part hereof to
  be null, void or unenforceable, or order any party to take any action
  inconsistent herewith or not to take an action consistent herewith or
  required hereby, the validity, legality and enforceability of the remaining
  provisions and obligations contained or set forth herein shall not in any
  way be affected or impaired thereby. Upon any such holding that any
  provision of this Agreement is null, void or unenforceable, the parties
  will negotiate in good faith to modify this Agreement so as to effect the
  original intent of the parties as closely as possible in an acceptable
  manner to the end that the transactions contemplated by this Agreement are
  consummated to the extent possible. Except as otherwise contemplated by
  this Agreement, to the extent that a party hereto took an action
  inconsistent herewith or failed to take action consistent herewith or
  required hereby pursuant to an order or judgment of a court or other
  competent authority, such party shall incur no liability or obligation
  unless such party did not in good faith seek to resist or object to the
  imposition or entering of such order or judgment.
 
    (h) Injunctive Relief. The parties acknowledge that it will be impossible
  to measure in money the damages that would be suffered if the parties fail
  to comply with any of the obligations herein imposed on them and that in
  the event of any such failure, an aggrieved person or entity will be
  irreparably damaged and will not have an adequate remedy at law. Any such
  person or entity shall, therefore, be entitled to injunctive relief,
  including specific performance, to enforce such obligations, and if any
  action should be brought in equity to enforce any of the provisions of this
  Agreement, none of the parties shall raise the defense that there is an
  adequate remedy at law.
 
    (i) Attorneys' Fees. If any party to this Agreement brings an action to
  enforce its rights under this Agreement, the prevailing party shall be
  entitled to recover its costs and expenses, including without limitation
  reasonable attorneys' fees, incurred in connection with such action,
  including any appeal of such action.
 
    (j) Cumulative Remedies. All rights and remedies of either party hereto
  are cumulative of each other and of every other right or remedy such party
  may otherwise have at law or in equity, and the exercise of one or more
  rights or remedies shall not prejudice or impair the concurrent or
  subsequent exercise of other rights or remedies.
 
    (k) Counterparts. This Agreement may be executed in two or more
  counterparts, all of which shall be considered one and the same instrument
  and shall become effective when executed and delivered by each of the
  parties.
 
                                      K-3

    (l) Amendments, Waivers, Etc.
 
      (i) This Agreement may not be amended, changed, supplemented, waived
    or otherwise modified or terminated, except upon the execution and
    delivery of a written agreement executed by the parties hereto.
 
      (ii) In the enforcement, interpretation or amendment of any
    provisions herein by Newco affecting the rights and obligations of HE
    or its Affiliates following the Closing, Newco shall be represented by
    a subcommittee of the Board of Directors of Newco comprised solely of
    Disinterested Directors.
 
      (iii) HE hereby agrees that no failure or delay by PAS, S Company or
    Newco, as the case may be, in exercising any right or remedy that any
    may have hereunder shall operate as a waiver of such right or remedy.
    HE hereby waives notice or demand of performance in the acceptance of
    its obligations hereunder. HE agrees that PAS, S Company or Newco may
    at any time, without notice to or consent of HE, and without in any
    manner affecting the liability of HE hereunder, amend, extend, modify,
    supplement or waive any term or condition of the Reorganization
    Agreement, and HE shall be bound by, and this Agreement shall
    automatically extend to the Reorganization Agreement as so amended,
    extended, modified, supplemented or waived without any action required
    by HE. The liability and obligations of HE hereunder shall be primary,
    direct and absolute and HE hereby waives any right to require that
    resort be had against any other person.
 
  IN WITNESS WHEREOF, the parties have executed this Assurance Agreement as of
the date first written above.

Agreement and the Univisa Contribution Agreement, HCI and Galaxy have required
that the Stockholders agree, and the Stockholders have agreed, to enter into
this Agreement.
 
                                   AGREEMENT
 
  In consideration of the foregoing and the mutual promises contained herein
and for other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the parties hereto, intending to be legally
bound, agree as follows:
 
  1. Certain Definitions. Capitalized terms used and not defined herein have
the respective meanings ascribed to them in the Reorganization Agreement. For
purposes of this Agreement:
 
    "Beneficially Own" or "Beneficial Ownership" with respect to any
  securities shall mean having "beneficial ownership" of such securities (as
  determined pursuant to Rule 13d-3 under the Exchange Act), including
  pursuant to any agreement, arrangement or understanding, whether or not in
  writing. Without duplicative counting of the same securities by the same
  holder, securities Beneficially Owned by a Person shall include securities
  Beneficially Owned by all other Persons with whom such Person would
  constitute a "group" within the meaning of Section 13(d) of the Exchange
  Act.
 
    "Common Stock" shall mean at any time the Class A Common Stock, par value
  $.01 per share, the Class B Common Stock, $.01 per share, and the Common
  Stock, par value $.01 per share, of Panamsat Corporation.
 
    "Existing Shares" shall mean the shares of Common Stock owned by the
  Stockholders on the date hereof.
 
    "Permitted Transfer" means a sale, transfer, assignment or other
  disposition to a Permitted Transferee.
 
    "Permitted Transferee" means, as to the Class A Holders, any other Class
  A Holder and any person who is (A) the spouse or former spouse of, or any
  lineal descendent of, or any spouse of such lineal descendant of, or the
  grandparent, parent, brother or sister of, or spouse of such brother or
  sister of, a Class
 
                                      L-1
<PAGE>
 
  A Holder or Permitted Transferee; (B) upon the death of any Class A Holder
  or any Permitted Transferee of such person, the executors of the estate of
  such Class A Holder or such Permitted Transferee, and any of such Class A
  Holder's or such Permitted Transferee's heirs, testamentary trustees,
  devisees, or legatees; (C) any trust principally for the benefit of one or
  more of the foregoing Class A Holders or Permitted Transferees; (D) upon
  the disability of any Class A Holder or Permitted Transferee, any guardian
  or conservator of such Class A Holder or such Permitted Transferee; or (E)
  any corporation, partnership or other entity if all of the beneficial
  ownership is held by Class A Holders or Permitted Transferees; provided
  that in each case such transferee assumes and agrees to perform and becomes
  a party to this Agreement, agrees not to make an Acquisition Proposal, and
  agrees not to dissent in the Merger, all on terms reasonably acceptable to
  HCI and Galaxy, and provided further that as a result of any such transfer
  no Class A Common Stock is converted into Common Stock, par value $.01 per
  share, of Panamsat Corporation. For purposes of this Agreement, when a
  Permitted Transferee has acquired Shares in accordance herewith, such
  person shall be deemed a "Stockholder" hereunder.
 
    "Person" shall mean an individual, corporation, limited liability
  company, partnership, joint venture, association, trust, unincorporated
  organization or other entity.
 
    "Shares" shall mean the Existing Shares and any shares of Common Stock
  acquired by any Stockholder in any capacity after the date hereof and prior
  to the termination of this Agreement. "Shares" shall include Shares
  acquired upon the exercise of options, warrants or rights, the conversion
  or exchange of convertible or exchangeable securities, or by means of
  purchase, dividend, distribution, gift, bequest, inheritance or as a
  successor in interest in any capacity or otherwise. In the event of a stock
  dividend or distribution, or any change in the Common Stock by reason of
  any stock dividend, split-up, recapitalization, reclassification,
  combination, exchange of shares or the like, the term "Shares" shall be
  deemed to refer to and include the Shares as well as all such stock
  dividends and distributions and any shares into which or for which any or
  all of the Shares may be changed, reclassified or exchanged and appropriate
  adjustments shall be made to the terms and provisions of this Agreement.
  "Shares" shall also include voting trust certificates issued in respect of
  any Shares. Notwithstanding the foregoing, "Shares" shall not include
  Common Stock issued upon exercise of Panamsat Corporation employee options
  covering up to 200,000 shares, which options are outstanding on the date
  hereof.
 
  2. Voting of Shares; No Inconsistent Agreements.
 
  (a) Each Stockholder hereby severally and not jointly and solely with
respect to the Shares held of record or Beneficially Owned by such
Stockholder, agrees that during the period commencing on the date hereof and
continuing until the termination of this Agreement in accordance with its
terms, at any meeting (whether annual or special and whether or not an
adjourned or postponed meeting) of the holders of Common Stock, however
called, or in connection with any written consent of the holders of Common
Stock, such Stockholder shall vote (or cause to be voted) the shares of Common
Stock held of record or Beneficially Owned by such Stockholder (i) in favor of
the Merger, the execution, delivery and performance of the Reorganization
Agreement and the approval and adoption of the terms thereof and each of the
other actions contemplated by the Reorganization Agreement and this Agreement
and any actions required in furtherance thereof and hereof (the "Subject
Transactions"); (ii) against any Acquisition Proposal and against any action
or agreement that would result in a breach in any respect of any covenant,
representation or warranty or any other obligation or agreement under the
Reorganization Agreement or the Univisa Contribution Agreement or this
Agreement; and (iii) except as otherwise agreed to in writing in advance by
HCI and Galaxy, and regardless of the status of the Merger and the
transactions contemplated by this Agreement, the Reorganization Agreement, or
the Univisa Contribution Agreement, against the following actions (other than
pursuant to the terms of this Agreement, the Reorganization Agreement, or the
Univisa Contribution Agreement): (A) any extraordinary corporate transaction,
such as a merger, consolidation or other business combination involving
Panamsat Corporation or any of its Subsidiaries; (B) any sale, lease or
transfer by Panamsat Corporation of a material amount of assets (including
stock) of Panamsat Corporation or any of its Subsidiaries, or a
reorganization, restructuring, recapitalization, special dividend, dissolution
or liquidation of Panamsat Corporation or any of its Subsidiaries; or (C)(1)
any change in a
 
                                      L-2
<PAGE>
 
majority of the persons who constitute the board of directors of Panamsat
Corporation or any of its Subsidiaries; (2) any change in the present
capitalization of Panamsat Corporation or any of its Subsidiaries including
any proposal to sell a substantial equity interest in Panamsat Corporation or
any of its Subsidiaries; (3) any amendment of Panamsat Corporation or any of
its Subsidiaries' charters or By-laws; (4) any other change in Panamsat
Corporation or any of its Subsidiaries' corporate structure or business; or
(5) any other action which, in the case of each of the matters referred to in
clauses (C)(1), (2), (3) or (4), is intended, or could reasonably be expected,
to impede, interfere with, delay, postpone, or materially adversely affect the
Merger and the transactions contemplated by this Agreement, the Reorganization
Agreement and the Univisa Contribution Agreement.
 
  (b) Each Stockholder severally and not jointly agrees that it shall not
enter into any agreement or understanding with any Person the effect of which
would be inconsistent with or violative of the provisions and agreements
contained herein, including in this Section 2. Further, each Stockholder
severally and not jointly agrees that it will, if the Board of Directors of
Panamsat Corporation fails or refuses (other than as a result of breach by HCI
or any of its Affiliates of the Reorganization Agreement or because HCI and
its Affiliates will not or cannot satisfy the conditions precedent thereto) to
submit the Subject Transactions to Panamsat Corporation stockholders, vote all
Shares held of record or Beneficially Owned by it to (i) call or cause to be
called a special meeting of stockholders of Panamsat Corporation (or effect a
written consent) to remove the directors of Panamsat Corporation who have so
failed or refused, or to increase the size of the Board of Directors and elect
a majority of new directors who will submit the Subject Transactions to the
stockholders of Panamsat Corporation for a vote, and (ii) use its reasonable
efforts to effect such removal and replacement, or increase and election, and
the submission of the Subject Transactions to the stockholders of Panamsat
Corporation; and (iii), at any time after initial approval by the stockholders
of Panamsat Corporation of the Subject Transactions, if so requested by HCI,
to approve all or any actions incident to the Subject Transactions or the
other matters referred to in this Section 2 by stockholder written consent.
 
  3. Other Stockholder Covenants.
 
  (a) Restriction on Transfer; Proxies and Non-interference. From the date
hereof through the Closing Date or the earlier termination of this Agreement
in accordance with its terms, and except for Permitted Transfers or as
expressly permitted herein or by the Reorganization Agreement or the Univisa
Contribution Agreement in connection with the transactions contemplated hereby
and thereby, each Stockholder severally and not jointly agrees that it shall
not directly or indirectly:
 
    (i) offer for sale, sell, transfer, tender, pledge, encumber, assign or
  otherwise dispose of, or enter into any contract, option or other
  arrangement or understanding with respect to, or consent to the offer for
  sale, sale, transfer, tender, pledge, encumbrance, assignment or other
  disposition of (collectively, "transfer"), any or all of the Shares or any
  interest therein; provided that nothing in this Agreement shall in any
  manner restrict the ability of the Stockholders to pledge or encumber any
  Shares in connection with one or more bona fide loans or advances to such
  Stockholder by one or more institutional lenders, but only if and so long
  as (A) each such lender expressly (on behalf of itself and any transferee
  of the collateral) assumes and agrees to perform and becomes a party to
  this Agreement, agrees not to make an Acquisition Proposal, and agrees not
  to dissent in the Merger, which agreement shall be on terms reasonably
  acceptable to HCI and Galaxy, (B) as a result of such pledge or encumbrance
  the subject Shares are not converted into Common Stock, par value $ .01 per
  share, of Panamsat Corporation, and (C), in the event of any foreclosure or
  other sale or retention of Shares by such a lender, the subject Shares are
  so converted (a loan or advance meeting such requirements being herein
  called a "Loan");
 
    (ii) grant any proxies or powers of attorney, deposit the Shares into a
  voting trust or enter into a voting agreement with respect to the Shares;
  provided that nothing in this Agreement shall in any manner restrict the
  ability of any Stockholder to enter into any voting agreement in connection
  with any Loan which is operative only upon default under such Loan and is
  not inconsistent with this Agreement; or
 
    (iii) take any action that would make any representation or warranty of
  such Stockholder contained herein untrue or incorrect or would result in a
  breach by such Stockholder of its obligations under this Agreement or a
  breach by Panamsat Corporation of its obligations under the Reorganization
  Agreement.

Notwithstanding the foregoing, at any time or times prior to the Closing S
Company (and, indirectly, the Class B Holder), on the one hand, and the Class
A Holders as a group, on the other hand, and their respective Permitted
Transferees, shall each have the right to sell, directly or indirectly, up to
an aggregate of 2,500,000 Shares (i.e., up to an aggregate of 5,000,000 Shares
collectively); provided that, by mutual agreement between S Company and the
Class A Holders, the foregoing Share amounts may be increased to up to
5,000,000 Shares each (i.e., up to an aggregate of 10,000,000 Shares,
collectively). Except for Shares converted to Common Stock, par value $.01 per
share, of Panamsat Corporation and sold in a registered public offering or
pursuant to Rule 144 under the Securities Act (which shall upon such sale
cease to be subject to this Agreement), Shares transferred pursuant to the
next preceding sentence may be transferred only if the Shares upon transfer
are converted to Common Stock, par value $.01 per share, of Panamsat
Corporation, and, on terms reasonably acceptable to HCI and Galaxy, the
transferee assumes and agrees to perform and becomes a party to this
Agreement, agrees not to make an Acquisition Proposal, and not to dissent in
the Merger. Notwithstanding any of the foregoing, no transfer of Shares may be
made during a period of up to 30 days prior to the Closing commencing on such
date as HCI shall notify the Stockholders to cease transfers pursuant to this
sentence.
 
  (b) No Solicitation.
 
    (i) From the date hereof through the Closing Date or the earlier
  termination of this Agreement in accordance with its terms, each
  Stockholder severally and not jointly agrees that it shall not, and shall
  not permit any of its Subsidiaries, or any of its or their officers,
  directors, employees, representatives, agents or Affiliates (including,
  without limitation, any investment banker, attorney or accountant retained
  by any Stockholder) to, directly or indirectly, enter into, solicit,
  initiate or continue any discussions or negotiations with, or encourage or
  respond to any inquiries or proposals by, or participate in any
  negotiations with, or provide any information to, or otherwise cooperate in
  any other way with, any Person or group, other than HCI, Galaxy and their
  Affiliates, concerning any Acquisition Proposal. Each Stockholder severally
  and not jointly agrees that it will immediately notify HCI and Galaxy if
  any discussions or negotiations are sought to be initiated, any inquiry or
  proposal is made, or any information is requested with respect to any
  Acquisition Proposal, and notify HCI and Galaxy of the terms of any
  proposal which it may receive in respect of any such Acquisition Proposal,
  including the identity of the prospective purchaser or soliciting party if
  known.
 
    (ii) Each Stockholder severally and not jointly further agrees to use its
  best efforts as a stockholder to cause Panamsat Corporation not to,
  directly or indirectly, solicit, initiate, seek, or encourage (including by
  way of furnishing information or assistance), or take other action to
  facilitate, any inquiries or the making of any proposal which constitutes
  or may reasonably be expected to lead to, an Acquisition Proposal.
 
    (iii) The provisions of this Section 3(b) shall not prohibit any director
  of Panamsat Corporation from taking actions in his capacity as such which
  are permitted or required under the Reorganization Agreement.
 
  (c) Reliance. Each Stockholder understands and acknowledges that HCI and
Galaxy are entering into the Reorganization Agreement and the Univisa
Contribution Agreement in reliance upon each Stockholder's execution and
delivery of this Agreement.
 
  (d) Further Assurances. From time to time, at HCI or Galaxy's request and
without further consideration, each Stockholder severally and not jointly
agrees that it shall execute and deliver such additional documents and take
all such further lawful action as may be necessary or desirable to consummate
and make effective, in the most expeditious manner practicable, the
transactions contemplated by this Agreement. Without limitation, each Class A
Holder which is a party thereto and the Class A Trustee agrees severally and
not jointly that it will cause the Voting Trust Agreement dated as of February
28, 1995 to be amended to the extent required (if any) to permit each and all
of them to enter into and perform this Agreement.
 
  (e) Stockholder Termination Fee. In the event that the Reorganization
Agreement is terminated in circumstances under which the Termination Fee is
payable by Panamsat Corporation to HCI pursuant to Section 9.3 of the
Reorganization Agreement, and any Acquisition Proposal is consummated, then
each Stockholder shall pay to HCI one business day after determination of an
amount (the "Stockholder Termination Fee") equal to
 
                                      L-4
<PAGE>
 
the product of (x) the number of Shares Beneficially Owned by such Stockholder
on the date hereof (as set forth on Exhibit A hereto), multiplied by (y) the
excess of (i) the per share value of consideration paid or payable in
consequence of consummation of the Acquisition Proposal (with the value of any
non-cash consideration being determined by agreement of HCI and such
Stockholder) over (ii) $30. In the event that the consideration paid or
payable in consequence of consummation of the Acquisition Proposal: (i)
consists solely of cash, then the Stockholder Termination Fee shall be payable
solely in cash, or (ii) consists of cash and other non-cash property, or
solely non-cash property, then the Stockholder Termination Fee shall be
payable in cash and such non-cash property in the same proportion as the cash
bears to the value of the non-cash property issued or issuable in consequence
of consummation of the Acquisition Proposal (as such value is determined
above).
 
  If HCI and such Stockholder fail to agree promptly on the value of such non-
cash consideration, then the parties shall appoint an independent investment
banking firm reasonably acceptable to HCI and such Stockholder to act as
arbitrator (the "Arbitrator"). Upon the selection of the Arbitrator, HCI on
the one hand and such Stockholder on the other shall deliver to the Arbitrator
and to each other their last and final offer concurrently in writing (the
"Certified Offers"). The Certified Offers shall list one amount which the
submitting party asserts is the appropriate valuation of such non-cash
consideration as of the date of submittal. The Arbitrator's sole role shall be
to select which one of the two Certified Offers most closely approximates the
valuation the Arbitrator would have determined for such non-cash
consideration, taking into account current market valuations of any publicly
traded securities which constitute such non-cash consideration. The Arbitrator
shall notify the parties of such determination. The determination of the
Arbitrator shall be binding on the parties. All costs and expenses of the
Arbitrator shall be borne by the parties whose Certified Offer is not
selected.
 
  Each Stockholder acknowledges that the agreements contained in this Section
3(e) are an integral part of the transactions contemplated by this Agreement
and the Reorganization Agreement. Accordingly, if the Stockholder shall fail
to pay when due any amounts which shall become due under Section 3(e) hereof,
the Stockholder shall in addition hereto pay to HCI all costs and expenses
(including fees and disbursements of counsel) incurred in collecting such
overdue amounts, together with interest on such overdue amounts from the date
such payment was required to be made until the date such payment is received
at a rate per annum equal to the "reference rate" as announced from time to
time by Bank of America, NT&SA. Any payment required to be made pursuant to
this Section 3(e) shall be made when due by wire transfer of immediately
available funds to an account designated by HCI.

severally and not jointly (and solely with respect to itself and the Shares
held of record or Beneficially Owned by such Stockholder) represents and

  transactions contemplated hereby or compliance by such Stockholder with any
  of the provisions hereof shall (A) conflict with or result in any breach of
  the organizational documents of such Stockholder, (B) result in a violation
  or breach of, or constitute (with or without notice or lapse of time or
  both) a default (or give rise to any third party right of termination,
  cancellation, material modification or acceleration) under any of the
  terms, conditions or provisions of any note, loan agreement, bond,
  mortgage, indenture, license, contract, commitment, arrangement,
  understanding, agreement or other instrument or obligation of any kind to

  other person is entitled to any broker's, finder's, financial adviser's or
  other similar fee or commission in connection with the transactions

  Stockholder.
 
  5. Representations and Warranties of HCI and Galaxy. HCI and Galaxy jointly
and severally represent and warrant to the Stockholders as follows:
 
    (a) Organization. Each of HCI and Galaxy is a corporation duly organized,
  validly existing and in good standing under the laws of its state of
  incorporation, and has all requisite corporate power or other power and

terminate upon the earliest of (i) the Closing Date, (ii) termination of the
Reorganization Agreement in accordance with its terms, or (iii) termination of
the Univisa Contribution Agreement in accordance with its terms; provided that
the provisions of Section 3(e) and of Section 10 shall survive any termination

limitation". This Agreement shall not be construed for or against either party

  (e) Entire Agreement; No Third-Party Beneficiaries. This Agreement
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof and is not intended to confer upon any person other than
the parties hereto any rights or remedies hereunder.
 
  (f) Assignment. Except in connection with Permitted Transfers or as
permitted in Section 3(a), neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned (whether by operation of
law or otherwise) by any Stockholder without the consent of HCI and Galaxy, or
by HCI or Galaxy without the consent of the Stockholders holding 66 2/3% of
the Shares subject to this Agreement. Subject to the preceding sentence, this
Agreement will be binding upon, inure to the benefit of and be enforceable by
the parties and their respective successors and assigns.
 
  (g) Governing Law. This Agreement shall be construed, interpreted and the
rights of the parties determined in accordance with the laws of the State of
Delaware (without reference to the choice of law provisions), except with
respect to matters of law concerning the internal corporate affairs of any
corporate entity which is a party to or the subject of this Agreement, and as
to those matters the law of the jurisdiction under which the respective entity
derives its powers shall govern.
 
  (h) Severability. Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part hereof to be
null, void or unenforceable, or order any party to take any action
inconsistent herewith or not to take an action consistent herewith or required
hereby, the validity, legality and enforceability of the remaining provisions
and obligations contained or set forth herein shall not in any way be affected
or impaired thereby. Upon any such holding that any provision of this
Agreement is null, void or unenforceable, the parties will negotiate in good
faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that the
transactions contemplated by this Agreement are consummated to the extent
possible. Except as otherwise contemplated by this Agreement, to the extent
that a party hereto took an action inconsistent herewith or failed to take
action consistent herewith or required hereby pursuant to an order or judgment
of a court or other competent authority, such party shall incur no liability
or obligation unless such party did not in good faith seek to resist or object
to the imposition or entering of such order or judgment.
 
  (i) Injunctive Relief. The parties acknowledge that it will be impossible to
measure in money the damages that would be suffered if the parties fail to
comply with any of the obligations herein imposed on them and that in the
event of any such failure, an aggrieved person or entity will be irreparably
damaged and will not have an adequate remedy at law. Any such person or entity
shall, therefore, be entitled to injunctive relief, including specific
performance, to enforce such obligations, and if any action should be brought
in equity to enforce any of the provisions of this Agreement, none of the
parties shall raise the defense that there is an adequate remedy at law.
 
  (j) Attorneys' Fees. If any party to this Agreement brings an action to
enforce its rights under this Agreement, the prevailing party shall be
entitled to recover its costs and expenses, including without limitation
reasonable attorneys' fees, incurred in connection with such action, including
any appeal of such action.
 
  (k) Cumulative Remedies. All rights and remedies of either party hereto are
cumulative of each other and of every other right or remedy such party may
otherwise have at law or in equity, and the exercise of one or more rights or
remedies shall not prejudice or impair the concurrent or subsequent exercise
of other rights or remedies.
 
  (l) Counterparts. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same instrument and
shall become effective when executed and delivered by each of the parties.
 
 
                                      L-9

  (m) Amendments, Waivers, Etc. This Agreement may not be amended, changed,
supplemented, waived or otherwise modified or terminated, except upon the
execution and delivery of a written agreement executed by the parties hereto.
 
  (n) Binding Agreement. Each Stockholder agrees that this Agreement and the
obligations hereunder shall attach to the Shares and, except as permitted in
Section 3(a), shall be binding upon any person or entity to which legal or
Beneficial Ownership of such shares shall pass, whether by operation of law or
otherwise, including, without limitation, such Stockholder's heirs,
distributees, guardians, administrators, executors, legal representatives, or
successors or other transferees (for value or otherwise) and any other
successors in interest. Notwithstanding any transfer of Shares, except as
provided in Section 3(a), the transferor shall remain liable for the
performance of all obligations under this Agreement of the transferor.
 
  (o) Obligations of the Stockholders. The liabilities and obligations of each
Stockholder under any provision of this Agreement are several and not joint
and apply solely to such Stockholder and to the Shares held of record or
Beneficially Owned by such Stockholder. No Stockholder shall have any
liability or obligation under this Agreement for any act, omission or breach
by any other Stockholder.
 
  (p) Service of Process. Each of the parties hereto irrevocably consents to
the service of any process, pleading, notices or other papers by the mailing
of copies thereof by registered, certified or first class mail, postage
prepaid, to such party at such party's address set forth herein, or by any

  2. Certain Restrictions on the Purchase and Sale of Shares.
 
  (a) Take-Along Right. HCI on behalf of itself and its Affiliates hereby
agrees:
 
    (i) With respect to any proposed HCI Sale, each Minority Stockholder
  (each a "Take-Along Stockholder"), shall have the right (the "Take-Along
  Right") to join in such sale and to sell a number of whole Shares equal to
  the number derived by multiplying the total number of Shares proposed to be
  transferred by a fraction, the numerator of which is the total number of
  Shares owned by such Take-Along Stockholder and the denominator of which is
  the total number of Shares owned by HCI and its Affiliates and all Take-
  Along Stockholders proposing to so join.
 
    (ii) Any Shares purchased from Take-Along Stockholders pursuant to this
  Section 2(a) shall be paid for at the same price per Share and (to the
  extent applicable) upon the same terms and conditions as such proposed
  transfer by HCI and its Affiliates.
 
    (iii) HCI shall (on its own behalf and on behalf of any of its Affiliates
  effecting an HCI Sale), not less than 30 days prior to such proposed HCI
  Sale, notify each Take-Along Stockholder in writing of such HCI Sale (the
  "Sale Notice"). Such notice shall: (A) state the number of Shares proposed
  to be transferred, (B) identify the proposed purchaser(s), (C) state the
  proposed amount and form of consideration and terms and conditions of
  payment, and (D) confirm that each proposed purchaser has been informed of
  the Take-Along Right provided for in this Section 2(a) and has agreed to
  purchase Shares in accordance with the terms thereof.
 
    (iv) The Take-Along Right may be exercised by any Take-Along Stockholder
  by delivery of a written notice to HCI proposing to sell Shares (the "Take-
  Along Notice") within 30 days following the Sale Notice, which Take-Along
  Notice shall state the amount of Shares that such Take-Along Stockholder
  proposes to include in such transfer. If no Take-Along Notice is received
  during such 30-day period, HCI and its Affiliates shall have the right, for
  a 30-day period after the expiration of such 30-day period, to transfer the
  Shares specified in the Sale Notice on terms and conditions no more
  favorable than those stated in such notice.
 
    (v) In the event that a purchaser refuses to purchase Shares from the
  Take-Along Stockholders on the same terms and conditions as specified in
  the Sale Notice, then HCI and its Affiliates shall not sell any Shares to
  that purchaser in the HCI Sale.
 
  (b) Certain Sale Restrictions.
 
    (i) Neither HCI nor its Affiliates may, directly or indirectly, issue,
  sell, exchange or otherwise dispose of, or offer or agree, directly or
  indirectly, to issue, sell, exchange or otherwise dispose (including
  through purchase by the Company or any of its Affiliates) of Shares or
  common equity of the Company or any of its Subsidiaries, or any interest
  therein, or securities convertible into or exercisable or exchangeable for
  Shares or such common equity interests, or offer or enter into any
  contract, option or other arrangement or understanding to effect any such
  transactions, during the period (A) beginning on the Closing and (B) ending
  on the Ending Date, provided, however, that restrictions on sales by the
  Company shall not commence (the "Commencement Date") until the earlier of
  (x) the first anniversary of the Closing (eighteen months following the
  Closing in the event the Minority Stockholders or their Affiliates sell
  more than five million Panamsat Shares (other than to Permitted
  Transferees) between the date of the Reorganization Agreement and the
  Closing) and (y) the date the Company shall notify the Minority
  Stockholders that it has completed the refinancing of up to $1.725 billion
  of indebtedness incurred by the Company in connection with the transactions
  contemplated by the Reorganization Agreement and the Univisa Contribution
  Agreement (it being agreed that the exemption from the restriction on sales
  by the Company pursuant to this clause shall only apply to sales, the net
  proceeds of which are entirely used to refinance such indebtedness); and
  provided further that the foregoing restrictions shall not apply to
 
                                      M-3
<PAGE>
 
  reasonable issuances by the Company for employee plans, in acquisitions
  from non-Affiliates, pursuant to a dividend reinvestment plan, or upon
  exercise or conversion of previously issued options, warrants or
  convertible securities.
 
    (ii) Each of the Minority Stockholders agrees severally and not jointly
  and solely with respect to itself and the Shares owned beneficially or of
  record by it, not to offer, sell or transfer the Shares, or any interest
  therein, or securities convertible into Shares, or offer or enter into any
  contract, option or other arrangement or understanding to effect any sale
  or transfer of Shares or interests therein or securities convertible into
  or exercisable or exchangeable for Shares, to any person that is not a
  Permitted Transferee, after the Closing and prior to the Commencement Date.
  Notwithstanding the foregoing, Minority Stockholders may offer and sell or
  transfer Shares, or interests therein, or securities convertible into or
  exercisable or exchangeable for Shares, to persons other than Permitted
  Transferees in private transactions with the consent of HCI, which consent
  will be granted if, in HCI's reasonable judgment, such transfer will not
  materially and adversely affect Holding Company's financing plans or on the
  price of or demand for Holding Company Common Stock, and the purchaser
  provides assurances satisfactory to HCI that it will not prior to the
  Commencement Date sell any of such Shares at a time or with an effect which
  may materially and adversely affect such financing plans of Holding Company
  or the price of or demand for Holding Company Common Stock. Further
  notwithstanding the foregoing, the Minority Stockholders may pledge their
  Shares as collateral for a bona fide loan, provided that the lender, on
  terms reasonably acceptable to HCI and the Company, agrees that upon
  liquidation of such collateral the lender or any transferee will assume and
  agree to perform this Agreement or, if requested by HCI or the Company,
  waive all rights under this Agreement.
 
  (c) Standstill Right. HCI agrees that HCI and its Affiliates shall not
acquire or come to hold beneficially or otherwise, whether by purchase,
exchange or otherwise, more than 81% of the outstanding common equity
interests in Holding Company, except (i) pursuant to a merger which is
approved by the holders of a majority of the shares of Holding Company Common
Stock not owned by HCI and its Affiliates, (ii) pursuant to a tender offer
recommended by a majority of the Disinterested Directors of the Holding
Company and second-step merger which offers the same per share consideration
to all holders of Holding Company Common Stock and in which more than half the
outstanding Holding Company Common Stock not owned by HCI and its Affiliates
at the inception of the transaction is either tendered or voted in favor of
the transaction, and (iii) except pursuant to such other transaction as shall
provide for parity of treatment of holders of Holding Company Common Stock and
is approved by the holders of a majority of the shares of Holding Company
Common Stock not owned by HCI and its Affiliates and by a majority of the
Disinterested Directors of Holding Company.
 
  3. Governance and Business Operations.
 
  (a) Board of Directors. The Stockholders, on behalf of themselves and their
Affiliates and Permitted Transferees, hereby agree to take all necessary
action (including, without limitation, voting the Common Stock of the Company
beneficially owned by them, calling special meetings of stockholders of the
Company and executing and delivering written consents) such that the Board of
Directors of the Company shall consist of ten (10) members designated as
herein provided. HCI shall designate all members of the Board of Directors not
designated by the Minority Stockholders. For so long as Mr. Frederick A.
Landman is Chief Executive Office of the Company, he shall be one of HCI's
designees. The Minority Stockholders shall be entitled to initially designate
two (2) directors of the Company, one (1) of whom may be designated by the
Class A Holders and one (1) of whom may be designated by S Company. For so
long as the Class A Holders and their Permitted Transferees, as a group (the
"A Group"), beneficially own a number of Shares which is greater than the
number of shares comprising 4% of the outstanding Common Stock of the Company
immediately after the consummation of the transactions contemplated by the
Reorganization Agreement and the Univisa Contribution Agreement and prior to
any further issuances for refinancing or other purposes (as such Shares may be
adjusted to reflect stock splits, combinations, stock dividends,
recapitalizations, reclassifications, and similar transactions, the "Director
Minimum Shares"), at each subsequent meeting of stockholders of the Company
(or action by consent in lieu thereof), the A Group shall be entitled to
designate one director, to be selected by a majority vote of the Shares
beneficially owned by the A Group. For so long as S Company and its Permitted
Transferees, as a group (the "B Group"), beneficially own a number of Shares
greater than the Director Minimum Shares, at each subsequent
 
                                      M-4
<PAGE>
 
meeting of stockholders of the Company (or action by consent in lieu thereof),
the B Group shall be entitled to designate one director, to be selected by a
majority vote of the Shares beneficially owned by the B Group. Any vacancy of
an available A Group or B Group director position will be filled promptly
without holding a meeting of stockholder's of the Company at the request of
the A Group or B Group, as applicable, with their designee; provided that the
A Group or B Group, as applicable, shall beneficially own a number of shares
greater than the Director Minimum Shares at the time of filing.
 
  (b) Transactions with Affiliates. HCI and its Affiliates (other than the
Company and its Subsidiaries) shall not propose or approve any loan, advance
or guarantee to, from, or for the benefit of, or sell, lease, transfer or
otherwise dispose of any of their properties or assets to, or for the benefit
of, or purchase or lease any property or assets from, or enter into or amend
any contract, agreement or understanding with, Holding Company or any
Subsidiary of Holding Company, except on terms that are no less favorable to
Holding Company or such Subsidiary than those (including, without limitation,
prices) ordinarily entered into in comparable transactions by HCI or the
relevant Affiliate on an arms' length basis with an unrelated party. All
material transactions (and all other transactions which the Chief Executive
Officer of the Holding Company may designate) between HCI and its Affiliates
on the one hand, and Holding Company or its Subsidiaries on the other, shall
be reviewed by a committee comprised of Disinterested Directors, and approval
of such transactions by such committee shall be conclusive evidence of
compliance with the provisions of this Section 3(b). Upon such approval,
unless required by such directors after due consideration, Holding Company or
such Subsidiaries may enter into and perform the approved transactions with
HCI and its Affiliates without competitive bidding or other special
procedures.
 
  (c) HE Covenant Not to Compete. HCI agrees:
 
    (i) Until the fifth anniversary after the Closing Date, HE and any entity
  owned 50% or more by HE (excluding Holding Company and its Subsidiaries)
  (the "Committing Companies") shall not compete with Holding Company or any
  of its Subsidiaries after the Closing in the "Galaxy Business" (as defined
  below) in any geographic area except as allowed under subsection (iii)
  below.
 
    (ii) As used herein, the "Galaxy Business" shall mean: (A) the sale or
  lease of, or the provision of satellite services via, transponder capacity
  on satellites operating in geostationary earth orbit in the C-band, Ka-band
  and Ku-band frequencies for the transmission of video, audio and data
  signals; and (B) the provision of telemetry, tracking and control services
  for such satellites and for other satellites operating in geostationary
  earth orbit in the C-band, Ka-band, Ku-band, L-band and UHF-band
  frequencies or other frequency bands that may be utilized in the future;
  but in each case excluding the sale or lease of transponder capacity and
  telemetry, tracking and control services provided on or for any satellite
  that has both (x) multiple (six or more) receive and transmit beams and (y)
  an on-board satellite payload processor which can switch uplink signals in
  one beam to a downlink signal in one of multiple beams.
 
    (iii) The Committing Companies shall not be restricted from conducting
  any business that falls within the following categories (the "Exclusivity
  Exceptions"):
 
      (A) All aspects of the direct-to-home satellite business, whether
    done through Galaxy Latin America, DIRECTV International, Inc., DIRECTV
    USA or any other entity owned 50% or more by HE including, but not
    limited to, (x) the provision of services directly to consumers via
    satellite; (y) the sale or lease of transponders or channels therein to
    third parties engaging in the direct-to-home satellite business in
    which any of the Committed Companies is involved (whether by ownership
    of an interest in a satellite or any part of the capacity thereof or in
    any related or associated business), whether in the FSS or BSS bands;
    and (z) the provision of programming to cable head ends, which in each
    of cases (y) and (z) is ancillary to any direct-to-home satellite
    business in which the Committing Companies have an interest; provided
    that if there is excess capacity available on a satellite used
    primarily in the direct-to-home satellite business, the sale or lease
    of such excess capacity shall not be precluded by the foregoing
    restriction;
 
      (B) All aspects of value added services, i.e., the sale of business
    services which include the provision of transponder capacity that is
    ancillary to the provision of such services by the Committing Companies
    including, but not limited to, shared hub VSAT business or DIRECPC or
    distance learning
 
                                      M-5
<PAGE>
 
    or any similar type of services that may now or in the future be
    provided or developed by HE or any of its Affiliates (other than
    Holding Company and its Subsidiaries);
 
      (C) All aspects of the business of providing satellite or transponder
    capacity or portions thereof of any type or kind to the United States
    government, or any department or agency thereof;
 
      (D) The provision by the Committing Companies of project financing,
    or the acceptance by any of them of a minority equity position in any
    other satellite operating or service company, as part of a satellite
    sale;
 
      (E) All aspects of the business of manufacturing and selling or
    leasing satellites in their entirety, other than the sale or lease of
    individual transponders or portions thereof (except with respect to
    such sale or lease of transponders as otherwise provided for in this
    Section (iii)); and
 
      (F) As part of the acquisition of a third party where the competing
    business is not a substantial part of such acquired business provided
    that such competing business shall be disposed of in a commercially
    reasonable manner as soon as commercially reasonable after such
    acquisition.
 
    (iv) The parties acknowledge that the Galaxy Business does not include,
  and the Committing Companies are retaining, the following: all aspects of
  the business of providing mobile satellite services and all aspects of the
  satellite-based business commonly referred to by HE as the "Spaceway"
  business.
 
  (d) Holding Company's Covenant Not to Compete. Holding Company and its
controlled Affiliates shall not engage in any aspect of the direct broadcast
satellite business other than through the sale or lease of transponders or
channels therein or the provision of transponder services and the provision of
other value added services ancillary thereto to third parties engaged in the
direct broadcast satellite business, provided that Holding Company and its
Subsidiaries shall not be precluded from providing project financing to such
third parties or the acceptance of a minority equity position in a third party
in connection with the sale or lease of transponders or channels therein or
the provision of transponder services. For so long as Grupo Televisa, S.A. and
its controlled Affiliates own any Holding Company Common Stock, neither
Holding Company nor any of its controlled Affiliates will own an equity
interest in a direct-to-home enterprise offering predominantly Spanish
language programming in the Americas or the Iberian Peninsula.
 
  (e) First Offer Rights. In the event that Holding Company determines to
launch a satellite with the following frequencies: Ku BSS frequencies (11.7-
12.5 Ghz in Region 1, 12.2-12.7 Ghz in Region 2 and 11.7-12.2 Ghz in Region 3)
(the "BSS Band") into any of the following orbital slots as such orbital slots
may be modified in the FCC authorization process, the ITU registration
process, or in the course of frequency coordination with other systems: East
Longitude: 36(degrees), 40(degrees), 48(degrees), 54(degrees), 101(degrees),
124.5(degrees), 132(degrees), 149(degrees), 164(degrees) and 173(degrees); and
West Longitude: 49(degrees) and 67(degrees) (the "BSS Satellites"), the
Company shall give HE or its designated Subsidiaries (referred to herein as
the "HE Designee") notice of such determination and the HE Designee shall have
the opportunity (the "First Opportunity") to enter into a full life service
agreement with respect to some or all, but not less than half of the available
capacity in the BSS Band on the applicable BSS Satellite, of the BSS
transponders (the "BSS Transponders") on the first BSS Satellite that the
Company intends to place into each such slot on terms and conditions to be
negotiated in good faith and consistent with normal business practice. The
negotiation period with respect to capacity on each such BSS Satellite shall
be for three months (the "Negotiation Period"). The Negotiation Period may be
initiated by either party on notice to the other at any time within the time
period set forth below. Applied separately to each BSS Satellite, the
Negotiation Period shall begin on the date on which the Company notifies the
HE Designee of a firm commitment to construct a BSS Satellite; and shall
commence not more than thirty months prior to the proposed launch of the BSS
Satellite and end not later than fifteen (15) months prior to the date that
the BSS Satellite is scheduled to be launched. If negotiations are not
initiated by either party by such date or successfully concluded with a
binding service agreement within the Negotiation Period, unless HE has given
Company a final offer (as defined below), neither party shall have any further
obligation pursuant to this Section 3(e), with respect to the BSS Satellite in
question. The conclusion or failure to conclude such an agreement as to one
orbital slot shall not, however, affect the parties' rights and obligations
hereunder as to the remaining BSS Satellites for other orbital slots
referenced in this Section, if still extant.
 
                                      M-6
<PAGE>
 
  At any time prior to the end of the applicable negotiation period specified
above, HE shall have the right to make to the Company HE's "best and final
offer" (a "Final Offer") of the price at which it is willing to enter into an
end of life service agreement for a stated number of BSS Transponders on the
BSS Satellite, which must be on terms and conditions that are otherwise
acceptable to the Company.
 
  If HE makes the Final Offer, for as long as it is held open (i.e., that it
may be accepted by the Company without HE's subsequent right to withdraw it),
the Company will not, without first offering HE the opportunity to do so,
enter into a purchase or long term transponder service agreement for the same
number or fewer BSS Band transponders than proposed by HE at a lower price per
BSS Transponder (which, for the purposes of comparison, will be calculated on
a net present value basis as determined by the Company, but notified to HE so
that HE may make an adjustment in its offer to reflect this net present value)
than the price stated in the Final Offer. The Company may condition its offer
to HE on HE's acceptance of such other price, quantity, length of term and
other terms and conditions that the Company would offer a third party at the
time (the "Revised Offer"). HE shall have ten (10) days to accept the
Company's Revised Offer or it shall be deemed to have been rejected. For the
avoidance of doubt, the previous sentence shall not apply to the Company's
acceptance of the Final Offer, as to which no further acceptance or rejection
by HE is required or permitted. The Company shall also notify HE at such time
as the Company lowers its price for long term transponder agreements on the
applicable BSS satellite for the number of transponders and for the service
terms which had been included in the Final Offer, which notice shall be given
not fewer than ten (10) business days before the reduced price is offered to
any third party, during which period HE will have the right to accept such
revised offer. As used in this Section 3(e), "Company" or "Holding Company"
includes its Subsidiaries or any of them.

Stockholder hereby severally and not jointly (and solely with respect to
itself and the Shares owned of record or beneficially by such Stockholder)

<PAGE>
 
  execution of this Agreement by such Minority Stockholder and the

  except that (i) such enforcement may be subject to applicable bankruptcy,
  insolvency, or other similar laws, now or hereafter in effect, affecting
  creditors' rights generally, and (ii) the remedy of specific performance

request Holding Company to register the transfer (by book-entry or otherwise)
of any certificate or uncertificated interest representing any of the Shares,
unless such transfer is made in compliance with this Agreement.
 
  (b) Each Stockholder severally and not jointly agrees that it shall promptly
after the date hereof surrender to Holding Company all certificates
representing the Shares held by such Stockholder, and Holding Company shall
place the following legend on such certificates, which legend shall remain on
such certificates until the sale of such Shares to a person who is not a

                                      M-8
<PAGE>
 
    "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN
    AGREEMENT, DATED AS OF    , 199  BETWEEN STOCKHOLDERS AND THE
    COMPANY. THE SHARES ARE SUBJECT TO RESTRICTIONS ON TRANSFER AND
    VOTING. A COPY OF SUCH AGREEMENT IS AVAILABLE AT THE PRINCIPAL
    OFFICE OF THE COMPANY."

with the transactions contemplated by the Reorganization Agreement described
in Recital A and the Univisa Contribution Agreement described in Recital B and

receipt requested. In each case notice shall be sent to: [to come].
 
  (c) Interpretation. When a reference is made in this Agreement to Sections,
such reference shall be to a Section of this Agreement unless otherwise
indicated. Headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement. Whenever the word "include", "includes" or "including" are used in
this Agreement, they shall be deemed to be followed by the words "without
limitation". This Agreement shall not be construed for or against either party
by reason of the authorship or alleged authorship of any provision hereof or
by reason of the status of the respective parties. All terms defined in this
Agreement in the singular shall have comparable meanings when used in the
plural, and vice versa, unless otherwise specified.
 
  (d) Entire Agreement; No Third-Party Beneficiaries. This Agreement
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof and is not intended to confer upon any person other than
the parties hereto any rights or remedies hereunder.
 
  (e) Assignment. Except to a Permitted Transferee, neither this Agreement nor
any of the rights, interests or obligations hereunder shall be assigned
(whether by operation of law or otherwise) by any Minority Stockholder without
the consent of HCI or by HCI or its Affiliates without the consent of Minority
Stockholders holding 66 2/3% of the Shares held by Minority Stockholders,
which consent may be granted or withheld in such party's discretion. Subject
to the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors
and assigns. No person who is not a Stockholder or Permitted Transferee who
acquires Shares shall have any rights under this Agreement except to the
extent that the assignment thereof has been approved as required by Section
8(e), nor any obligations hereunder except to the extent expressly assumed.
 
  (f) Governing Law. This Agreement shall be construed, interpreted and the
rights of the parties determined in accordance with the laws of the State of
Delaware (without reference to the choice of law provisions), except with
respect to matters of law concerning the internal corporate affairs of any
corporate entity
 
                                      M-9
<PAGE>
 
which is a party to or the subject of this Agreement, and as to those matters
the law of the jurisdiction under which the respective entity derives its
powers shall govern.
 
  (g) Severability. Each party agrees that, should any court or other
competent authority hold any provision of this Agreement or part hereof to be
null, void or unenforceable, or order any party to take any action
inconsistent herewith or not to take an action consistent herewith or required
hereby, the validity, legality and enforceability of the remaining provisions
and obligations contained or set forth herein shall not in any way be affected
or impaired thereby. Upon any such holding that any provision of this
Agreement is null, void or unenforceable, the parties will negotiate in good
faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that the
transactions contemplated by this Agreement are consummated to the extent
possible. Except as otherwise contemplated by this Agreement, to the extent
that a party hereto took an action inconsistent herewith or failed to take
action consistent herewith or required hereby pursuant to an order or judgment
of a court or other competent authority, such party shall incur no liability
or obligation unless such party did not in good faith seek to resist or object
to the imposition or entering of such order or judgment.
 
  (h) Injunctive Relief. The parties acknowledge that it will be impossible to
measure in money the damages that would be suffered if the parties fail to
comply with any of the obligations herein imposed on them and that in the
event of any such failure, an aggrieved person or entity will be irreparably
damaged and will not have an adequate remedy at law. Any such person or entity
shall, therefore, be entitled to injunctive relief, including specific
performance, to enforce such obligations, and if any action should be brought
in equity to enforce any of the provisions of this Agreement, none of the
parties shall raise the defense that there is an adequate remedy at law.
 
  (i) Attorneys' Fees. If any party to this Agreement brings an action to
enforce its rights under this Agreement, the prevailing party shall be
entitled to recover its costs and expenses, including without limitation
reasonable attorneys' fees, incurred in connection with such action, including
any appeal of such action.
 
  (j) Cumulative Remedies. All rights and remedies of either party hereto are
cumulative of each other and of every other right or remedy such party may
otherwise have at law or in equity, and the exercise of one or more rights or
remedies shall not prejudice or impair the concurrent or subsequent exercise
of other rights or remedies.
 
  (k) Counterparts. This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same instrument and
shall become effective when executed and delivered by each of the parties.
 
  (l) Amendments, Waivers, Etc. This Agreement may not be amended, changed,
supplemented, or otherwise modified or terminated, except upon the execution
and delivery of a written agreement executed by the parties hereto; provided
that performance hereof by any Minority Stockholder may be waived by HCI and
performance hereof by HCI, its Affiliates or the Company may be waived by
Minority Stockholders holding 66 2/3% of the Shares held by Minority
Stockholders.
 
  (m) Obligations of Stockholders. The liabilities and obligations of each
Stockholder under any provision of this Agreement are several and not joint
and apply solely to such Stockholder and to the Shares held of record or
beneficially owned by such Stockholder. No Stockholder shall have any
liability or obligation under this Agreement for any act, omission or breach
by any other Stockholder.
 
  (n) Service of Process. Each of the parties hereto irrevocably consents to
the service of any process, pleading, notices or other papers by the mailing
of copies thereof by registered, certified or first class mail, postage
prepaid, to such party at such party's address set forth herein, or by any
other method provided or permitted under Delaware law. Additionally, each
party hereby appoints RL&F Service Corp., One Rodney Square, Wilmington,
Delaware 19810, as agent for service of process in Delaware.

  (o) Consent and Jurisdiction. Each party irrevocably and unconditionally
agrees and consents that any suit, action or other legal proceeding arising
out of or related to this Agreement shall be brought and heard in New Castle
County, State of Delaware, and each party irrevocably consents to personal
jurisdiction in any and all tribunals in said County.
 
  IN WITNESS WHEREOF, the parties have executed this Amended and Restated

  have the right during the Registration Period, by written notice (the
  "Demand Notice") given to the Company, to request the
 
                                      N-3
<PAGE>
 
  Company to register under and in accordance with the provisions of the
  Securities Act all or any portion of the Registrable Shares designated by
  such Holders; provided, however, that the aggregate value (at the
  respective dates of such notices) of Registrable Shares requested to be
  registered pursuant to any Demand Notice and pursuant to any related
  Inclusion Notices received pursuant to the following sentence shall be at
  least $100 million. Upon receipt of any such Demand Notice, the Company
  shall promptly notify all other Holders of the receipt of such Demand
  Notice and allow them the opportunity to include Registrable Shares held by
  them in the proposed registration by submitting their own written notice to
  the Company requesting inclusion of a specified number of such Holders'
  Registrable Securities (the "Inclusion Notice"). In connection with any
  Demand Registration in which more than one Holder participates, in the
  event that such Demand Registration involves an underwritten offering and
  the managing underwriter or underwriters participating in such offering
  advise in writing the Holders of Registrable Shares to be included in such
  offering that the total number of Registrable Shares to be included in such
  offering exceeds the amount that can be sold in (or during the time of)
  such offering without delaying or jeopardizing the success of such offering
  (including the price per share of the Registrable Shares to be sold), then
  the amount of Registrable Shares to be offered for the account of such
  Holders shall be reduced pro rata on the basis of the number of Registrable
  Shares to be registered by each such Holder; provided if the registration
  of Registrable Shares held by Mary Anselmo is necessary in connection with
  any payment of estate taxes by her estate, such registration by the estate
  of Mary Anselmo shall have priority over any registration of Registrable
  Shares by a Class B Holder or any Holder who acquired such securities
  directly or indirectly from or through a Class B Holder. The Class A
  Holders as a group and the Class B Holders as a group shall each be
  entitled to three Demand Registrations pursuant to this Section 2; Hughes
  Communications, Inc. shall be entitled to six Demand Registrations pursuant
  to this Section 2; if any such Demand Registration does not become
  effective or is not maintained for a period (whether or not continuous) of
  at least 180 days (or such shorter period as shall terminate when all the
  Registrable Shares covered by such Demand Registration (other than any
  shares reserved for issuance upon exercise of the underwriters'
  overallotment option) have been sold pursuant thereto), the affected
  Holders will be entitled to an addition Demand Registration pursuant
  hereto. It is agreed that the registration of Registrable Shares pursuant
  to an Inclusion Notice shall not be deemed to be a Demand Registration.
  Nothing in this Section 2(a) shall limit any rights pursuant to Section 3
  hereof. Nothing in this Agreement shall limit the rights and obligations of
  the parties under the Stockholder Agreement, including pursuant to Sections
  2(a) and 2(b) thereof. Notwithstanding anything herein to the contrary, the
  exercise of each Demand Registration under this Section 2(a) by the Class A
  Holders shall require the approval of the Class A Holders, and their
  Permitted Transferees, owning a majority of the Registrable Shares then
  owned by all Class A Holders and their Permitted Transferees.
 
    (b) The Company, within 45 days of the date on which the Company receives
  a Demand Notice given by Holders in accordance with Section 2(a) hereof,
  shall file with the SEC, and the Company shall thereafter use commercially
  reasonable efforts to cause to be declared effective, a Registration
  Statement on the appropriate form for the registration and sale, in
  accordance with the intended method or methods of distribution, of the
  total number of Registrable Shares specified by the Holders in such Demand
  Notice, which may include a "shelf" registration (a "Shelf Registration")
  pursuant to Rule 415 under the Securities Act (a "Demand Registration").
 
    (c) The Company shall use commercially reasonable efforts to cause the
  Registration Statement to be declared effective and to keep each
  Registration Statement filed pursuant to this Section 2 continuously
  effective and usable for the resale of the Registrable Shares covered
  thereby (i) in the case of a Registration that is not a Shelf Registration,
  for a period of 90 days from the date on which the SEC declares such
  Registration Statement effective and (ii) in the case of a Shelf
  Registration, for a period of 180 days from the date on which the SEC
  declares such Registration Statement effective, in either case (x) until
  all the Registrable Shares covered by such Registration Statement (other
  than any shares reserved for issuance upon exercise of the underwriters'
  overallotment option) have been sold pursuant to such Registration
  Statement, and (y) as such period may be extended pursuant to this Section
  2.
 
    (d) The Company shall be entitled to postpone the filing of any
  Registration Statement otherwise required to be prepared and filed by the
  Company pursuant to this Section 2, or suspend the use of any
 
                                      N-4
<PAGE>
 
  effective Registration Statement under this Section 2, for a reasonable
  period of time, but not in excess of 90 days (a "Delay Period"), if the
  chief executive officer or chief financial officer of the Company
  determines that in such executive officer's reasonable judgment and good
  faith the registration and distribution of the Registrable Shares covered
  or to be covered by such Registration Statement would materially interfere
  with any pending material financing, acquisition or corporate
  reorganization or other material corporate development involving the
  Company or any of its subsidiaries or would require premature disclosure
  thereof and promptly gives the Holders written notice of such
  determination, containing a general statement of the reasons for such
  postponement and an approximation of the period of the anticipated delay;
  provided, however, that (i) the aggregate number of days included in all
  Delay Periods during any consecutive 12 months shall not exceed the
  aggregate of (x) 120 days minus (y) the number of days occurring during all
  Hold Back Periods and Interruption Periods during such consecutive 12
  months and (ii) a period of at least 60 days shall elapse between the
  termination of any Delay Period, Hold Back Period or Interruption Period
  and the commencement of the immediately succeeding Delay Period. If the
  Company shall so postpone the filing of a Registration Statement, the
  Holders of Registrable Shares to be registered shall have the right to
  withdraw the request for registration by giving written notice from the
  Holders of a majority of the Registrable Shares that were to be registered
  to the Company within 45 days after receipt of the notice of postponement
  or, if earlier, the termination of such Delay Period (and, in the event of
  such withdrawal, such request shall not be counted for purposes of
  determining the number of requests for registration to which the Holders of
  Registrable Shares are entitled pursuant to this Section 2). The time
  period for which the Company is required to maintain the effectiveness of
  any Registration Statement shall be extended by the aggregate number of
  days of all Delay Periods, all Hold Back Periods and all Interruption
  Periods occurring during such Registration and such period and any
  extension thereof is hereinafter referred to as the "Effectiveness Period."
  The Company shall not be entitled to initiate a Delay Period unless it
  shall (A) to the extent permitted by agreements with other security holders
  of the Company, concurrently prohibit sales by such other security holders
  under registration statements covering securities held by such other
  security holders and (B) in accordance with the Company's policies from
  time to time in effect, forbid purchases and sales in the open market by
  senior executives of the Company.
 
    (e) The Company shall not include any securities that are not Registrable
  Shares in any Registration Statement filed pursuant to this Section 2
  without the prior written consent of (i) the Class A Holders of a majority
  in number of the Registrable Shares held by Class A Holders covered by such
  Registration Statement, and (ii) the Class B Holder(s) of a majority in
  number of the Registrable Shares held by such Class B Holders covered by
  such Registration Statement, and (iii) Hughes Communications, Inc. Holders
  with respect to Registrable Shares held by such Hughes Communications, Inc.
  Holders covered by such Registration Statement.
 
    (f) Holders of a majority in number of the Registrable Shares to be
  included in a Registration Statement pursuant to this Section 2 may, at any
  time prior to the effective date of the Registration Statement relating to
  such Registration, revoke such request by providing a written notice to the
  Company revoking such request. The Holders of Registrable Shares who revoke
  such request shall reimburse the Company for all its out-of-pocket expenses
  incurred in the preparation, filing and processing of the Registration
  Statement; provided, however, that, if such revocation was pursuant to
  Section 2(d) (for a postponement) or was based on the Company's failure to
  comply in any material respect with its obligations hereunder, such
  reimbursement shall not be required, and such registration shall not count
  against the maximum number of Demand Registrations to which the applicable
  Holders are entitled under Section 2(a). In addition, if pursuant to the
  terms of this Section 2(f), the Holders reimburse the Company for its out
  of pocket expenses incurred in the preparation, filing and processing of
  any Registration Statement requested, and subsequently revoked by such
  Holder(s), such registration shall not count against the maximum number of
  Demand Registrations to which the applicable Holder(s) are entitled under
  Section 2(a).
 
  3. Piggyback Registration.
 
    (a) Right to Piggyback. If at any time during the Registration Period the
  Company proposes to file a registration statement under the Securities Act
  with respect to a public offering of securities of the same
 
                                      N-5
<PAGE>
 
  type as the Registrable Shares pursuant to a firm commitment underwritten
  offering solely for cash for its own account (other than a registration
  statement (i) on Form S-8 or any successor forms thereto, or (ii) filed
  solely in connection with a dividend reinvestment plan or employee benefit
  plan of the Company or its Affiliates) or for the account of any holder of
  securities of the same type as the Registrable Shares (to the extent that
  the Company has the right to include Registrable Shares in any registration
  statement to be filed by the Company on behalf of such holder), then the
  Company shall give written notice of such proposed filing to the Holders at
  least 15 days before the anticipated effective date. Such notice shall
  offer the Holders the opportunity to register such amount of Registrable
  Shares as they may request (a "Piggyback Registration"). Subject to Section
  3(b) hereof, the Company shall include in each such Piggyback Registration
  all Registrable Shares with respect to which the Company has received
  written requests for inclusion therein within 10 days after notice has been
  given to the Holders. Each Holder shall be permitted to withdraw all or any
  portion of the Registrable Shares of such Holder from a Piggyback
  Registration at any time prior to the effective date of such Piggyback
  Registration; provided, however, that if such withdrawal occurs after the
  filing of the Registration Statement with respect to such Piggyback
  Registration, the withdrawing Holders shall reimburse the Company for the
  portion of the registration expenses payable with respect to the
  Registrable Shares so withdrawn.
 
    (b) Priority on Piggyback Registrations. The Company shall permit the
  Holders to include all such Registrable Shares on-the-same terms and
  conditions as any similar securities, if any, of the Company included
  therein. Notwithstanding the foregoing, if the Company or the managing
  underwriter or underwriters participating in such offering advise the
  Holders in writing that the total amount of securities requested to be
  included in such Piggyback Registration exceeds the amount which can be
  sold in (or during the time of) such offering without delaying or
  jeopardizing the success of the offering (including the price per share of
  the securities to be sold), then the amount of securities to be offered for
  the account of the Holders and other holders of securities who have
  piggyback registration rights with respect thereto shall be reduced (to
  zero if necessary) pro rata on the basis of the number of common stock
  equivalents requested to be registered by each such Holder or holder
  participating in such offering.
 
    (c) Right to Abandon. Nothing in this Section 3 shall create any
  liability on the part of the Company to the Holders if the Company in its
  sole discretion should decide not to file a registration statement proposed
  to be filed pursuant to Section 3(a) hereof or to withdraw such
  registration statement subsequent to its filing and prior to the later of
  its effectiveness or the release of the Registrable Shares for public
  offering by the managing underwriter, in the case of an underwritten public
  offering, regardless of any action whatsoever that a Holder may have taken,
  whether as a result of the issuance by the Company of any notice hereunder
  or otherwise.
 
  4. Holdback Agreement. If (i) the Company shall file a registration
statement with respect to the Common Stock or similar securities or securities
convertible into, or exchangeable or exercisable for, such securities and (ii)
the Company (in the case of a nonunderwritten public offering by the Company
pursuant to such registration statement) advises the Holders in writing that a
public sale or distribution of Registrable Shares would materially adversely
affect such offering or the managing underwriter or underwriters (in the case
of an underwritten public offering by the Company pursuant to such
registration statement) advises the Company in writing (in which case the
Company shall notify the Holders) that a public sale or distribution of
Registrable Shares would have material adverse impact on such offering, then
each Holder shall, to the extent not inconsistent with applicable law, refrain
from effecting any public sale or distribution of Registrable Shares during
the 10 days prior to the effective date of such registration statement and
until the earliest of (A) the abandonment of such offering, (B) 90 days from
the effective date of such registration statement and (C) if such offering is
an underwritten offering, the termination of any "hold back" period obtained
by the underwriter or underwriters in such offering from the Company in
connection therewith (each such period, a "Hold Back Period").
 
  5. Registration Procedures. In connection with the registration obligations
of the Company pursuant to and in accordance with Sections 2 and 3 hereof (and
subject to Sections 2 and 3 hereof), the Company shall use commercially
reasonable efforts to effect such registration to permit the sale of such
Registrable Shares in
 
                                      N-6
<PAGE>
 
accordance with the intended method or methods of disposition thereof, and
pursuant thereto the Company shall as expeditiously as possible (but subject
to Sections 2 and 3 hereof):
 
    (a) At least ten (10) business days before filing a Registration
  Statement or prospectus or any amendments or supplements thereto, furnish
  to the Holders who are participating in such Registration Statement and the
  underwriters, if any, copies of all such documents proposed to be filed,
  which documents will be subject to the review of such Holders and such
  underwriters (and their respective counsel), and, in the case of a Demand
  Registration, the Company will not file any Registration Statement or
  amendment thereto or any prospectus or any supplement thereof to which the
  Registering Holders or the underwriters, if any, shall reasonably object;
 
    (b) prepare and file with the SEC a Registration Statement for the sale
  of the Registrable Shares on any form for which the Company then qualifies
  or which counsel for the Company shall deem appropriate in accordance with
  such Holders' intended method or methods of distribution thereof, subject
  to Section 2(b) hereof, and, subject to the Company's right to terminate or
  abandon a registration pursuant to Section 3(c) hereof, use commercially
  reasonable efforts to cause such Registration Statement to become effective
  and remain effective as provided herein;
 
    (c) prepare and file with the SEC such amendments (including post-
  effective amendments) to such Registration Statement, and such supplements
  to the related Prospectus, as may be required by the rules, regulations or
  instructions applicable to the Securities Act during the applicable period
  in accordance with the intended methods of disposition specified by the
  Holders of the Registrable Shares covered by such Registration Statement,
  make generally available earnings statements satisfying the provisions of
  Section 11(a) of the Securities Act (provided that the Company shall be
  deemed to have complied with this clause if it has complied with Rule 158
  under the Securities Act), and cause the related Prospectus as so
  supplemented to be filed pursuant to Rule 424 under the Securities Act;
  provided, however, that before filing a Registration Statement or
  Prospectus, or any amendments or supplements thereto (other than reports
  required to be filed by it under the Exchange Act), the Company shall
  furnish to the Holders of Registrable Shares covered by such Registration
  Statement and their counsel for review and comment, copies of all documents
  required to be filed;
 
    (d) notify the Holders of any Registrable Shares covered by such
  Registration Statement promptly and (if requested) confirm such notice in
  writing, (i) when a Prospectus or any Prospectus supplement or post-
  effective amendment has been filed, and, with respect to such Registration
  Statement or any post-effective amendment, when the same has become
  effective, (ii) of any request by the SEC for amendments or supplements to
  such Registration Statement or the related Prospectus or for additional
  information regarding such Holders, (iii) of the issuance by the SEC of any
  stop order suspending the effectiveness of such Registration Statement or
  the initiation of any proceedings for that purpose, (iv) of the receipt by
  the Company of any notification with respect to the suspension of the
  qualification or exemption from qualification of any of the Registrable
  Shares for sale in any jurisdiction or the initiation or threatening of any
  proceeding for such purpose, and (v) of the happening of any event that
  requires the making of any changes in such Registration Statement,
  Prospectus or documents incorporated or deemed to be incorporated therein
  by reference so that they will not contain any untrue statement of a
  material fact or omit to state any material fact required to be stated
  therein or necessary to make the statements therein not misleading:
 
    (e) use commercially reasonable efforts to obtain the withdrawal of any
  order suspending the effectiveness of such Registration Statement, or the
  lifting of any suspension of the qualification or exemption from
  qualification of any Registrable Shares for sale in any jurisdiction in the
  United States;
 
    (f) furnish to the Holder of any Registrable Shares covered by such
  Registration Statement, each counsel for such Holders and each managing
  underwriter, if any, without charge, one conformed copy of such
  Registration Statement, as declared effective by the SEC, and of each post-
  effective amendment thereto, in each case including financial statements
  and schedules and all exhibits and reports incorporated or deemed to be
  incorporated therein by reference; and deliver, without charge, such number
  of copies of the preliminary prospectus, any amended preliminary
  prospectus, each final Prospectus and any post-
 
                                      N-7
<PAGE>
 
  effective amendment or supplement thereto, as such Holder may reasonably
  request in order to facilitate the disposition of the Registrable Shares of
  such Holder covered by such Registration Statement in conformity with the
  requirements of the Securities Act;
 
    (g) prior to any public offering of Registrable Shares covered by such
  Registration Statement, use commercially reasonable efforts to register or
  qualify such Registrable Shares for offer and sale under the securities or
  Blue Sky laws of such jurisdictions as the Holders of such Registrable
  Shares shall reasonably request in writing; provided, however, that the
  Company shall in no event be required to qualify generally to do business
  as a foreign corporation or as a dealer in any jurisdiction where it is not
  at the time so qualified or to execute or file a general consent to service
  of process in any such jurisdiction where it has not theretofore done so or
  to take any action that would subject it to general service of process or
  taxation in any such jurisdiction where it is not then subject;
 
    (h) upon the occurrence of any event contemplated by paragraph 5(d)(v)
  above, prepare a supplement or post-effective amendment to such
  Registration Statement or the related Prospectus or any document
  incorporated or deemed to be incorporated therein by reference and file any
  other required document so that, as thereafter delivered to the purchasers
  of the Registrable Shares being sold thereunder (including upon the
  termination of any Delay Period), such Prospectus will not contain an
  untrue statement of a material fact or omit to state any material fact
  required to be stated therein or necessary to make the statements therein,
  in light of the circumstances under which they were made, not misleading;
 
    (i) use commercially reasonable efforts to cause all Registrable Shares
  covered by such Registration Statement to be listed on each securities
  exchange or automated interdealer quotation system, if any, on which
  similar securities issued by the Company are then listed or quoted;
 
    (j) use commercially reasonable efforts to comply with all applicable
  rules and regulations of the SEC and any securities exchange or regulatory
  body;
 
    (k) on or before the effective date of such Registration Statement,
  provide the transfer agent of the Company for the Registrable Shares with
  printed certificates for the Registrable Shares covered by such
  Registration Statement which are in a form eligible for deposit with The
  Depository Trust Company;
 
    (l) if such offering is an underwritten offering, make available for
  inspection by any Holder of Registrable Shares included in such
  Registration Statement, any underwriter participating in any offering
  pursuant to such Registration Statement, and any attorney, accountant or
  other agent retained by any such Holder or underwriter (collectively, the
  "Inspectors"), such financial and other records and other information,
  pertinent corporate documents and properties of any of the Company and its
  subsidiaries and affiliates (collectively, the "Records"), as shall be
  reasonably necessary to enable them to exercise their due diligence
  responsibilities; provided, however, that the Records that the Company
  determines, in good faith, to be confidential and which it notifies the
  Inspector in writing are confidential shall not be disclosed to any
  Inspector unless such Inspector signs a confidentiality agreement
  reasonably satisfactory to the Company, which agreement shall permit the
  disclosure of such Records in such Registration Statement or the related
  Prospectus if either (i) the disclosure of such Records is necessary to
  avoid or correct a misstatement or omission in such Registration Statement
  or (ii) the release of such Records is ordered pursuant to a subpoena or
  other order from a court of competent jurisdiction; provided however, that
  (A) any decision regarding the disclosure of information pursuant to
  subclause (i) shall be made only after consultation with counsel for the
  applicable Inspectors and the Company and (B) with respect to any release
  of Records pursuant to subclause (ii), each Holder of Registrable Shares
  agrees that it shall, promptly after learning that disclosure of such
  Records is sought in a court having jurisdiction, give notice to the
  Company so that the Company, at the Company's expense, may undertake
  appropriate action to prevent disclosure of such Records; and
 
    (m) if such offering is an underwritten offering, enter into such
  agreements (including an underwriting agreement in form, scope and
  substance as is customary in underwritten offerings) and take all such
  other appropriate and reasonable actions requested by the Holders of a
  majority of the Registrable Shares being sold in connection therewith
  (including those reasonably requested by the managing underwriters) in
  order
 
                                      N-8
<PAGE>
 
  to expedite or facilitate the disposition of such Registrable Shares, and
  in such connection, (i) use commercially reasonable efforts to obtain
  opinions of counsel to the Company and updates thereof (which counsel and
  opinions (in form, scope and substance) shall be reasonably satisfactory to
  the managing underwriters and counsel to the Holders of the Registrable
  Shares being sold), addressed to each selling Holder of Registrable Shares
  covered by such Registration Statement and each of the underwriters as to
  the matters customarily covered in opinions requested in underwritten
  offerings and such other matters may be reasonably requested by such
  counsel and underwriters, (ii) use commercially reasonable efforts to
  obtain "cold comfort" letters and updates thereof from the independent
  certified public accountants of the Company (and, if necessary, any other
  independent certified public accountants of any subsidiary of the Company
  or of any business acquired by the Company for which financial statements
  and financial data are, or are required to be, included in the Registration
  Statement), addressed to each selling Holder of Registrable Shares covered
  by the Registration Statement (unless such accountants shall be prohibited
  from so addressing such letters by applicable standards of the accounting
  profession) and each of the underwriters, such letters to be in customary
  form and covering matters of the type customarily covered in "cold comfort"
  letters in connection with underwritten offerings (iii) if requested and if
  an underwriting agreement is entered into, provide indemnification
  provisions and procedures substantially to the effect set forth in Section
  8 hereof with respect to all parties to be indemnified pursuant to said
  Section. The above shall be done at each closing under such underwriting or
  similar agreement, or as and to the extent required thereunder. In
  addition, the Company agrees (i) not to effect any public sale or
  distribution of its Common Stock, par value $.01 per share, or any
  securities convertible into or exchangeable or exercisable for such
  securities, during the 10 days prior to the effective date of any
  underwritten Demand or Piggyback Registration and until the earliest of (A)
  the abandonment of such offering, or (B) the termination of any "hold back"
  period reasonably requested by the underwriters (with exceptions for
  issuances pursuant to outstanding options, warrants, and convertible or
  exchangeable securities, pursuant to employee and dividend reinvestment
  plans, and such other exceptions as are customary or agreed with the
  managing underwriter).
 
  The Company may require each Holder of Registrable Shares covered by a
Registration Statement to furnish such information regarding such Holder and
such Holder's intended method of disposition of such Registrable Shares as it
may from time to time reasonably request in writing. If any such information
is not furnished within a reasonable period of time after receipt of such
request, the Company may exclude such Holder's Registrable Shares from such
Registration Statement.
 
  Each Holder of Registrable Shares covered by a Registration Statement agrees
that, upon receipt of any notice from the Company of the happening of any
event of the kind described in Section 5(d)(ii), 5(d)(iii), 5(d)(iv) or
5(d)(v) hereof, that such Holder shall forthwith discontinue disposition of
any Registrable Shares covered by such Registration Statement or the related
Prospectus until receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 5(h) hereof, or until such Holder is
advised in writing (the "Advice") by the Company that the use of the
applicable Prospectus may be resumed, and has received copies of any amended
or supplemented Prospectus or any additional or supplemental filings which are
incorporated, or deemed to be incorporated, by reference in such Prospectus
(such period during which disposition is discontinued being an "Interruption
Period") and, if requested by the Company, the Holder shall deliver to the
Company (at the expense of the Company) all copies then in its possession,
other than permanent file copies then in such holder's possession, of the
Prospectus covering such Registrable Shares at the time of receipt of such
request.
 
  Each Holder of Registrable Shares covered by a Registration Statement
further agrees not to utilize any material other than the applicable current
preliminary prospectus or Prospectus in connection with the offering of such
Registrable Shares.
 
  6. Registration Expenses. Whether or not any Registration Statement is filed
or becomes effective, the Company shall pay all costs, fees and expenses
incident to the Company's performance of or compliance with this Agreement,
including (i) all registration and filing fees, including NASD filing fees,
(ii) all fees and expenses of compliance with securities or Blue Sky laws,
including reasonable fees and disbursements of counsel in
 
                                      N-9
<PAGE>
 
connection therewith, (iii) printing expenses (including expenses of printing
certificates for Registrable Shares and of printing preliminary and final
prospectuses if the printing of prospectuses is requested by the Holders or
the managing underwriter, if any), (iv) messenger, telephone and delivery
expenses, (v) fees and disbursements of counsel for the Company, (vi) fees and
disbursements of all independent certified public accountants of the Company
(including expense of any "cold comfort" letters required in connection with
this Agreement) and all other persons retained by the Company in connection
with this Agreement and the Registration Statement, and (vii) all other costs,
fees and expenses incident to the Company's performance or compliance with
this Agreement. Notwithstanding the foregoing, the fees and expenses of any
persons retained by any Holder, including counsel for such Holders, and any
discounts, commissions or brokers' fees or fees of similar securities industry
professionals and any transfer taxes relating to the disposition of the
Registrable Shares by a Holder, will be payable by such Holder and the Company
will have no obligation to pay any such amounts.
 
  7. Underwriting Requirements.
 
    (a) Subject to Section 7(b) hereof, any Holder giving a Demand Notice
  shall have the right, by written notice, to request that any Demand
  Registration provide for an underwritten offering.
 
    (b) In the case of any underwritten offering pursuant to a Demand
  Registration, the Holders of a majority of the Registrable Shares covered
  by the Demand Notice to be disposed of in connection therewith shall select
  the institution or institutions that shall manage or lead such offering,
  which institution or institutions shall be reasonably satisfactory to the
  Company. In the case of any underwritten offering pursuant to a Piggyback
  Registration, the Company shall select the institution or institutions that
  shall manage or lead such offering.
 
  8. Indemnification.
 
    (a) Indemnification by the Company. The Company shall, without limitation
  as to time, indemnify and hold harmless, to the full extent permitted by
  law, each Holder of Registrable Shares whose Registrable Shares are covered
  by a Registration Statement or Prospectus, the officers, directors and
  agents and employees of each of them, each Person who controls each such
  Holder (within the meaning of Section 15 of the Securities Act or Section
  20 of the Exchange Act) and the officers, directors, agents and employees
  of each such controlling person, to the fullest extent lawful, from and
  against any and all losses, claims, damages, liabilities, judgment, costs
  (including, without limitation, costs of preparation and reasonable
  attorneys' fees) and expenses (collectively, "Losses"), as incurred,
  arising out of or based upon any untrue or alleged untrue statement of a
  material fact contained in such Registration Statement or Prospectus or in
  any amendment or supplement thereto or in any preliminary prospectus, or
  arising out of or based upon any omission or alleged omission of a material
  fact required to be stated therein or necessary to make the statements
  therein not misleading, except insofar as the same are based upon
  information furnished in writing to the Company by or on behalf of such
  Holder expressly for use therein or by any underwriter in a Demand
  Registration; provided, however, that the Company shall not be liable to
  any such Holder to the extent that any such Losses arise out of or are
  based upon an untrue statement or alleged untrue statement or omission or
  alleged omission made in any preliminary prospectus if (i) having
  previously been furnished by or on behalf of the Company with copies of the
  Prospectus, such Holder failed to send or deliver a copy of the Prospectus
  with or prior to the delivery of written confirmation of the sale of
  Registrable Shares by such Holder to the person asserting the claim from
  which such Losses arise and (ii) the Prospectus would have corrected in all
  material respects such untrue statement or alleged untrue statement or such
  omission or alleged omission; and provided further, however, that the
  Company shall not be liable in any such case to the extent that any such
  Losses arise out of or are based upon an untrue statement or alleged untrue
  statement or omission or alleged omission in the Prospectus, if (x) such
  untrue statement or alleged untrue statement, omission or alleged omission
  is corrected in all material respects in an amendment or supplement to the
  Prospectus and (y) having previously been furnished by or on behalf of the
  Company with copies of the Prospectus as so amended or supplemented, such
  Holder thereafter fails to deliver such Prospectus as so amended or
  supplemented, prior to or currently with the sale of Registrable Shares. In
  connection with any Underwritten Offering, the Company will also indemnify
  underwriters, selling brokers, dealer managers and
 
                                     N-10
<PAGE>
 
  similar securities industry professionals participating in the
  distribution, their officers and directors and each Person who controls
  such Persons (within the meaning of Section 15 of the Securities Act) to
  the same extent as provided above with respect to Indemnification of
  Holders of Registrable Shares, or on such other terms as are reasonable and
  customary and requested by the managing underwriter.
 
    (b) Indemnification by Holder of Registrable Shares. In connection with
  any Registration Statement in which a Holder is participating, such Holder
  shall furnish to the Company in writing such information as the Company
  reasonably requests for use in connection with such Registration Statement
  or the related Prospectus and agrees to indemnify, to the full extent
  permitted by law, the Company, its directors, officers, agents or
  employees, each Person who controls the Company (within the meaning of
  Section 15 of the Securities Act and Section 20 of the Exchange Act) and
  the directors, officers, agents or employees of such controlling Persons,
  from and against all Losses arising out of or based upon any untrue or
  alleged untrue statement of a material fact contained in such Registration
  Statement or the related Prospectus or any amendment or supplement thereto,
  or any preliminary prospectus, or arising out of or based upon any omission
  or alleged omission of a material fact required to be stated therein or
  necessary to make the statements therein not misleading, to the extent, but
  only to the extent, that such untrue or alleged untrue statement or
  omission or alleged omission is based upon any information so furnished in
  writing by or on behalf of such Holder to the Company expressly for use in
  such Registration Statement or Prospectus.
 
    (c) If any Person shall be entitled to indemnity hereunder (an
  "Indemnified Party"), indemnified party shall give prompt notice to the
  party from which such indemnity is sought (the "Indemnifying Party") of any
  claim or of the commencement of any proceeding with respect to indemnitee
  party seeks indemnification or contribution pursuant hereto; provided,
  however, that the delay or failure to so notify the indemnifying party
  shall not relieve the indemnifying party from any obligation or liability
  except to the extent that the indemnifying party has been prejudiced by
  such delay or failure. The indemnifying party shall have the right,
  exercisable by giving written notice to an indemnified party promptly after
  the receipt of written notice from such indemnified party of such claim or
  proceeding, to assume, at the indemnifying party's expense, the defense of
  any such claim or proceeding, with counsel reasonably satisfactory to such
  indemnified party; provided, however, that (i) an indemnified party shall
  have the right to employ separate counsel in any such claim or proceeding
  and to participate in the defense thereof, but the fees and expenses of
  such counsel shall be at the expense of such indemnified party unless: (1)
  the indemnifying party agrees to pay such fees and expenses; (2) the
  indemnifying party fails promptly to assume the defense of such claim or
  proceeding or fails to employ counsel reasonably satisfactory to such
  indemnified party; or (3) the named parties to any proceeding (including
  impleaded parties) include both such indemnified party and the indemnifying
  party, and such indemnified party shall have been advised by counsel that
  there may be one or more legal defenses available to it that are
  inconsistent with those available to the indemnifying party or that a
  conflict of interest is likely to exist among such indemnified party and
  any other indemnified parties (in which case the indemnifying party shall
  not have the right to assume the defense of such action on behalf of such
  indemnified party); and (ii) subject to clause (3) above, the indemnifying
  party shall not, in connection with any one such claim or proceeding or
  separate but substantially similar or related claims or proceedings in the
  same jurisdiction, arising out of the same general allegations or
  circumstances, be liable for the fees and expenses of more than one firm of
  attorneys (together with appropriate local counsel) at any time for all of
  the indemnified parties, or for fees and expenses that are not reasonable.
  Whether or not such defense is assumed by the indemnifying party, such
  indemnified party shall not be subject to any liability for any settlement
  made without its consent. The indemnifying party shall not consent to entry
  of any judgment or enter into any settlement that does not include as an
  unconditional term thereof the giving by the claimant or plaintiff to such
  indemnified party of a release, in form and substance reasonably
  satisfactory to the indemnified party, from all liability in respect of
  such claim or litigation for which such indemnified party would be entitled
  to indemnification hereunder.
 
    (d) Contribution. If the indemnification provided for in this Section 8
  is unavailable to an indemnified party in respect of any Losses (other than
  in accordance with its terms), then each applicable indemnifying party, in
  lieu of indemnifying such indemnified party, shall contribute to the amount
  paid or payable by such indemnified party as a result of such Losses, in
  such proportion as is appropriate to reflect
 
                                     N-11
<PAGE>
 
  the relative fault of the indemnifying party, on the one hand, and such
  indemnified party, on the other hand, in connection with the actions,
  statements or omissions that resulted in such Losses as well as any other
  relevant equitable considerations. The relative fault of such indemnifying
  party, on the one hand, and indemnified party, on the other hand, shall be
  determined by reference to, among other things, whether any action in
  question, including any untrue statement of a material fact or omission or
  alleged omission to state a material fact, has been taken by, or relates to
  information supplied by, such indemnifying party or indemnified party, and
  the parties' relative intent, knowledge, access to information and
  opportunity to correct or prevent any such action, statement or omission.
  The amount paid or payable by a party as a result of any Losses shall be
  deemed to include any legal or other fees or expenses incurred by such
  party in connection with any investigation or proceeding. The parties
  hereto agree that it would not be just and equitable if contribution
  pursuant to this Section 8(d) were determined by pro rata allocation or by
  any other method of allocation that does not take account of the equitable
  considerations referred to in the this Section 8(d). Notwithstanding the
  provision of this Section 8(d), an indemnifying party that is a Holder
  shall not be required to contribute any amount which is in excess of the
  amount by which the total proceeds received by such Holder from the sale of
  the Registrable Shares sold by such Holder (net of all underwriting
  discounts and commissions) exceeds the amount of any damages that such
  indemnifying party has otherwise been required to pay by reason of such
  untrue or alleged untrue statement or omission or alleged omission. No
  person guilty of fraudulent misrepresentation (within the meaning of
  Section 11(f) of the Securities Act) shall be entitled to contribution from
  any Person who was not guilty of such fraudulent misrepresentation.
 
  9. Rule 144. If the Company shall have filed a registration statement
pursuant to the requirements of Section 12 of the Exchange Act or a
registration statement pursuant to the requirements of the Securities Act, the
Company covenants that it will timely file the reports required to be filed by
it under the Securities Act or the Exchange Act (including but not limited to
the reports under Sections 13 and 15(d) of the Exchange Act referred to in
subparagraph (c)(1) of Rule 144 adopted by the SEC under the Securities Act)
and the rules and regulations adopted by the SEC thereunder (or if the Company
is not required to file such reports, the Company will, upon the request of
any Holder of Registrable Shares, make publicly available other information),
and will take such further action as any Holder of Registrable Shares may
reasonably request, all to the extent required from time to time to enable
such Holder of Registrable Shares to sell Registrable Shares within the
exemption provided by (i) Rule 144 under the Securities Act, as such Rule may
be amended from time to time, or (ii) any similar rule or regulation hereafter
adopted by the SEC. Upon the request of any Holder of Registrable Shares, the
Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.
 
  10. Miscellaneous.
 
    (a) Termination. This Agreement and the obligations of the Company and
  the Holders hereunder (other than Section 8 hereof) shall terminate on the
  first date on which no Registrable Shares remain outstanding.
 
    (b) Notices. All notices, requests, demands and other communications
  which are required or may be given under this Agreement shall be in writing
  and shall be deemed to have been duly given when received if personally
  delivered; when transmitted if transmitted by telecopy, electronic or
  digital transmission method; the day after it is sent, if sent for next day
  delivery to a domestic address by recognized overnight delivery service
  (e.g., Federal Express); and upon receipt, if sent by certified or

  otherwise indicated. Headings contained in this Agreement are for reference
  purposes only and shall not affect in any way the meaning or interpretation
  of this Agreement. Whenever the word "include", "includes" or "including"

    (d) Entire Agreement; No Third-Party Beneficiaries. This Agreement
  constitutes the entire agreement and supersedes all prior agreements and
  understandings, both written and oral, among the parties with respect to
  the subject matter hereof and is not intended to confer upon any person
  other than the parties hereto any rights or remedies hereunder.
 
    (e) Assignment. Neither this Agreement nor any of the rights, interests,
  or obligations hereunder shall be assigned (whether by operation of law or
  otherwise) by any Holder without the consent of the Company, or by the
  Company without the consent of Holders of at least a majority in number of
  the Registrable Shares then outstanding provided that any Holder can assign
  its rights hereunder to a Permitted Transferee or Permitted Assignee of $15
  million or more in value of Common Stock without the consent of the
  Company. Subject to the preceding sentence, this Agreement will be binding
  upon, inure to the benefit of and be enforceable by the parties and their
  respective successors and assigns. In no event shall any transferee of
  Common Stock be entitled, solely as a result of such transfer, to any of
  the benefits of this Agreement or to enforce the same.
 
    (f) Governing Law. This Agreement shall be construed, interpreted and the
  rights of the parties determined in accordance with the laws of the State
  of Delaware (without reference to the choice of law provisions), except
  with respect to matters of law concerning the internal corporate affairs of
  any corporate entity which is a party to or the subject of this Agreement,
  and as to those matters the law of the jurisdiction under which the
  respective entity derives its powers shall govern.
 
    (g) Severability. Each party agrees that, should any court or other
  competent authority hold any provision of this Agreement or part hereof to
  be null, void or unenforceable, or order any party to take any action
  inconsistent herewith or not to take an action consistent herewith or
  required hereby, the validity, legality and enforceability of the remaining
  provisions and obligations contained or set forth herein shall not in any
  way be affected or impaired thereby. Upon any such holding that any
  provision of this Agreement is null, void or unenforceable, the parties
  will negotiate in good faith to modify this Agreement so as to effect the
  original intent of the parties as closely as possible in an acceptable
  manner to the end that the transactions contemplated by this Agreement are
  consummated to the extent possible. Except as otherwise contemplated by
  this Agreement, to the extent that a party hereto took an action
  inconsistent herewith or failed to take action consistent herewith or
  required hereby pursuant to an order or judgment of a court or other
  competent authority, such party shall incur no liability or obligation
  unless such party did not in good faith seek to resist or object to the
  imposition or entering of such order or judgment.
 
    (h) Injunctive Relief. The parties acknowledge that it will be impossible
  to measure in money the damages that would be suffered if the parties fail
  to comply with any of the obligations herein imposed on them and that in
  the event of any such failure, an aggrieved person or entity will be
  irreparably damaged and will not have an adequate remedy at law. Any such
  person or entity shall, therefore, be entitled to injunctive relief,
  including specific performance, to enforce such obligations, and if any
  action should be brought in equity to enforce any of the provisions of this
  Agreement, none of the parties shall raise the defense that there is an
  adequate remedy at law.
 
    (i) Attorneys' Fees. If any party to this Agreement brings an action to
  enforce its rights under this Agreement, the prevailing party shall be
  entitled to recover its costs and expenses, including without limitation
  reasonable attorneys' fees, incurred in connection with such action,
  including any appeal of such action.
 
    (j) Cumulative Remedies. All rights and remedies of any party hereto are
  cumulative of each other and of every other right or remedy such party may
  otherwise have at law or in equity, and the exercise of one or more rights
  or remedies shall not prejudice or impair the concurrent or subsequent
  exercise of other rights or remedies.
 
    (k) Counterparts. This Agreement may be executed in two or more
  counterparts, all of which shall be considered one and the same instrument
  and shall become effective when executed and delivered by each of the
  parties.
 
                                     N-13

    (l) Amendments and Waivers. Except as otherwise provided herein, the
  provisions of this Agreement may not be amended, modified or supplemented,
  and waivers or consents to departures from the provisions hereof may not be
  given, unless the Company has obtained the written consent of Holders of at
  least a majority in number of the Registrable Shares then outstanding, or
  the Holders have obtained the written consent of the Company.
 
    (m) Other Agreements. Without the approval of Holders owning at least
  two-thirds in interest of each of the Hughes Communications, Inc. Holders,
  the Class A Holders, and the Class B Holders of the Registrable Shares, the
  Company shall not enter into any registration rights agreement ranking pari
  passu or senior to this Agreement.
 
  IN WITNESS WHEREOF, the parties have executed this Amended and Restated
Registration Rights Agreement as of the date first above written.

realized, as hereinafter provided.

changes ("Tax Changes") to: (i) the federal income tax attributes of the
affected member or members of the Newco Group to be reflected in the
consolidated federal income tax returns, including amended returns with
respect to prior years, to be filed by the Newco Group; and (ii) the state and
local income tax attributes of the affected member or members of the Newco
Group to be reflected in the consolidated, combined or separate state and
local income tax returns, including amended returns with respect to prior
years, to be filed by the Newco Group or any member or members thereof.
 
  (c) With respect to each taxable year ending after the Closing Date, Newco
will calculate the Separate Federal Income Tax Liability of the Newco Group,
first, by taking into account, to the extent permitted by applicable law, all
Tax Changes, as described in all current and prior year Change Notices (the
"With Calculation"); and, second, by disregarding all such Tax Changes (the
"Without Calculation"). If the Newco Group's Separate Federal Income Tax
Liability under the With Calculation exceeds its Separate Federal Income Tax
Liability under the Without Calculation, HE shall pay the amount of such
excess to Newco. If the Newco Group's Separate Federal Income Tax Liability
under the Without Calculation exceeds its Separate Federal Income Tax
Liability under the With Calculation, Newco shall pay the amount of such
excess to HE.
 
  (d) With respect to each taxable year ending after the Closing Date, Newco
will calculate, for each applicable state and local jurisdiction, the Separate
State or Local Tax Liability of the Newco Group or the members thereof, on a
consolidated, combined or separate basis, as applicable, first, by taking into
account, to the extent permitted by applicable law, all Tax Changes, as
described in all current and prior year Change Notices (the "With
Calculation"); and, second, by disregarding all such Tax Changes (the "Without
Calculation"). If the Newco Group's Separate State or Local Tax Liability
under the With Calculation exceeds its Separate State or Local Tax Liability
under the Without Calculation, HE shall pay the amount of such excess to
Newco. If the Newco Group's Separate State or Local Tax Liability under the
Without Calculation exceeds its Separate State or Local Tax Liability under
the With Calculation, Newco shall pay the amount of such excess to HE.
 
  (e) All calculations and payments required pursuant to this Section 2.02
with respect to a taxable year shall be made by the due date (including
extensions) of Newco's consolidated federal income tax return for such year.
Newco shall, at least 60 days before such due date, deliver to HE, for its
review, work papers setting forth with reasonable specificity the With and
Without Calculations and the Tax Changes taken into account for purposes of
such Calculations.
 
  (f) If HE wishes to dispute any With and Without Calculations, it shall
deliver to Newco, within 30 days after receipt of Newco's work papers, a
notice ("Dispute Notice") specifying in recordable detail those items as to
which HE disagrees, the reasons for disagreement and its proposed adjustments
to the With and Without
 
                                      O-4
<PAGE>
 
Calculations. If a Dispute Notice is delivered, HE and Newco shall use their
reasonable best efforts to reach agreement on the disputed items or amounts.
If HE and Newco cannot reach agreement within 10 days of the delivery of a
Dispute Notice, the disputed items will be submitted to the Accounting Firm
for determination, as provided herein. The Accounting Firm shall deliver to HE
and Newco, as promptly as practicable, a written report setting forth its
determination of the disputed items, which determination shall be final,
conclusive and binding on the parties and shall not be subject to appeal to
any court or tribunal. HE and Newco shall each bear its own expenses in
connection with the preparation of work papers, the issuance of Dispute
Notices and the submission of disputes to the Accounting Firm, except that the
fees and expenses of the Accounting Firm shall be shared equally by HE and
Newco.
 
                                   ARTICLE 3
 
                STATE AND LOCAL INCOME TAXES OF OVERLAP GROUPS
 
  3.01 Applications. This Article 3 shall be applicable only to the extent
that HE determines, in its reasonable judgment, based on applicable state or
local law, or a state or local tax authority requires, that state or local
income tax returns should be filed with respect to an Overlap Group. The sole
obligations and rights to refunds of the Newco Group in respect of state and
local Income Taxes of an Overlap Group is as provided in this Article 3.
 
  3.02 Estimated Tax Payments. Not less than fifteen (15) business days prior
to the date on which Parent is required to make payments of estimated tax on
behalf of an Overlap Group (including payments of tax due with a request for
an extension to file), Newco shall submit to HE a calculation of the separate
estimated tax liability of the Affected Newco Group Members, determined based
on the Newco Overlap Tax (with respect to such Overlap Group) for the taxable
year in question. Newco shall pay the amount so calculated to HE not later
than the due date of Parent's estimated tax payment. Newco shall also remit to
HE the amount of any interest, penalties or other additions to tax which would
have been due on such estimated payment, if Newco had made such payment
directly to the applicable tax authority.
 
  3.03 Payment of Separate Group Tax Liability. For each taxable year (or
other period) of an Overlap Group, Newco, on behalf of the Affected Newco
Group Members, shall prepare and deliver to HE, within four months after the
end of the taxable year, a calculation of the Newco Overlap Tax (with respect
to such Overlap Group) for such taxable year (or other period). Not later than
the filing due date (including extensions) for the Overlap Group for such
taxable year, (a) Newco shall pay to HE the excess, if any, of the Newco
Overlap Tax for such taxable year (or applicable portion thereof) over the
estimated tax payments previously made by Newco to HE in respect thereof,
together with any interest, penalties or other additions to tax which would
have been due if Newco had made such payment directly to the applicable tax
authority, or (b) HE shall pay to Newco an amount equal to the excess, if any,
of such estimated tax payments previously made by Newco over such Newco
Overlap Tax, or (c) HE shall pay to Newco the amount of the Newco Overlap
Refund for such taxable year (or component thereof), if any, together with any
interest thereon which would have been receivable if Newco had received such
refund directly from the applicable taxing authority plus the amount of any
estimated tax payments previously made by Newco for such taxable year (or
portion thereof).
 
  3.04 Subsequent Adjustments. If the Overlap Group Tax Liability of an
Overlap Group (or any item entering into the computation thereof) is adjusted
by a state or local tax authority, then, as such adjustments become final, by
judicial decision, settlement, closing agreement or otherwise, the Newco
Overlap Tax (with respect to such Overlap Group) shall be recomputed to the
extent necessary to reflect such adjustments, and Newco shall pay to HE any
increase, or HE shall pay to Newco any decrease, in the Newco Overlap Tax. Any
such payment shall be due not later than (i) five business days before the due
date for any additional payment of tax by the Parent, (ii) five business days
after the receipt of a refund by any member of the Overlap Group or (iii) five
business days after the adjustment in question becomes final, if such
adjustment does not result in a payment of additional tax or receipt of a
refund. Newco shall also pay to HE any interest, penalties or additions
 
                                      O-5
<PAGE>
 
to tax which would have been due, if Newco had made such payment directly to
the applicable tax authority. The parties recognize that the Overlap Group Tax
Liability of an Overlap Group and the Newco Overlap Tax may be recomputed
under this Section 3.04 or Section 3.05 hereof more than once.
 
  3.05 Other Recomputations. If an adjustment to the Overlap Group Tax
Liability of an Overlap Group, or to the related Newco Overlap Tax, is not
provided for in Section 3.04 hereof (such as a recomputation of amounts due
hereunder to reflect a carryback item or an erroneous calculation), then
either HE or Newco, as the case may be, shall make a payment to the other in
such amount and at such time as shall be determined in accordance with the
principles of Section 3.04 hereof.
 
  3.06 Termination of Overlap Group. If an Overlap Group is terminated:
 
    (a) HE and Newco shall consult with and provide each other with such
  information as may relate to the prior inclusion of members of either Group
  in the Overlap Group.
 
    (b) Unless otherwise consented to by the Parent, neither the Newco Group
  nor any member thereof shall elect to carry back to a taxable year of an
  Overlap Group any losses or other tax attributes incurred in a
  Disaffiliation Year, unless otherwise required by law.
 
    (c) If net operating loss carryovers generated by an Affected Newco Group
  Member while included in an Overlap Group have not been used, prior to the
  first Disaffiliation Year, in calculating the related Newco Overlap Tax and
  have not expired, but rather have been used by the GM Group in a
  Disaffiliation Year or have otherwise been retained by the GM Group (the
  "Surviving NOL"), HE shall pay to Newco the amount, if any, by which, for a
  Disaffiliation Year, the state or local income tax liability of such
  Affected Newco Group Members would be reduced if the Surviving NOL (net of
  any portion hereof taken into account under this Section 3.06(c) in a prior
  Disaffiliation Year), were an available net operating loss carryforward to
  such Disaffiliation Year (subject to the expiration thereof or to any
  limitation on the use thereof under applicable state or local law). HE
  shall pay such amount to Newco not later than the date on which Newco is
  required to satisfy such state or local income tax liability for such
  Disaffiliation Year.
 
  3.07 Disputes. If HE or Newco disputes any calculation of any tax liability
or required payment under this Article 3, such dispute shall be finally
resolved by the Accounting Firm using the dispute resolution procedures set
forth in Article 2 hereof.
 
                                   ARTICLE 4
 
                           MISCELLANEOUS PROVISIONS
 
  4.01 Preparation and Filing of Tax Returns. HE shall prepare and timely file
or shall cause to be prepared and timely filed all Federal, state and local
Income Tax returns in respect of Galaxy, HCSS, HCS, HCCS and HCJ (the "HE
Subsidiaries"), their assets or activities that (i) are required to be filed
on or before the Closing Date or (ii) are required to be filed after the
Closing Date and (A) are includable in the Income Tax returns of the GM Group
or (B) are with respect to Income Taxes and are required to be filed on a
separate tax return basis for any taxable year (or period thereof) ending on
or before the Closing Date. Newco shall prepare or cause to be prepared and
shall file or cause to be filed all other tax returns required of HCS, HCCS
and HCJ, or in respect of their assets or activities (or the assets and
activities of Galaxy and HCSS transferred to Newco). Any such tax returns
filed after the date of this Agreement shall be prepared on a basis consistent
with the last previous such tax returns filed in respect of the HE
Subsidiaries, unless HE or Newco, as the case may be, concludes that there is
no reasonable basis for such position.
 
  4.02 Tax Sharing Agreements. From and after the Closing Date, neither the
Newco Group nor any member thereof shall be a party to or have any liability
under any tax sharing agreement or arrangement, other than this Agreement,
with any member of the GM Group.
 
 
                                      O-6
<PAGE>
 
  4.03 Carryforwards and Carrybacks. Newco shall cause HCS, HCCS and HCJ to
elect, where permitted by law, to carry forward any net operating loss,
charitable contribution or other item arising after the Closing Date that
could, in the absence of such an election, be carried back to a taxable period
of the GM Group ending on or before the Closing Date in which HCS, HCCS and
HCJ were included in a consolidated tax return of the GM Group. Newco, on its
own behalf and on behalf of its affiliates, hereby waives any right to use or
apply any net operating loss, charitable contribution or other item (other
than any net capital loss, foreign tax credit or research and development
credit which are not permitted by law to be carried forward) of HCS, HCCS and
HCJ for any tax year ending on any date following the Closing Date to any
period of HCS, HCCS, and HCJ ending on or before the Closing Date and reserves
the right to use or apply any such net capital loss, foreign tax credit or
research and development credit of HCS, HCCS, and HCJ for any tax year ending
on any date following the Closing Date to any period of HCS, HCCS or HCJ
ending on or before the Closing Date, provided, however, that if any such net
capital loss, foreign tax credit or research and development credit shall be
carried back to any such period, Newco shall indemnify HE and its affiliates
(other than HCS, HCCS and HCJ) for all reasonable costs and expenses incurred
by HE or any of such affiliates in filing such claims or in connection with
any audit of such claims.
 
  4.04 Refunds. HE shall be entitled to retain, or receive immediate payment
from Newco or any of its subsidiaries or affiliates (including HCS, HCCS and
HCJ) of, any refund or credit with respect to Income Taxes (including, without
limitation, refunds and credits arising by reason of amended tax returns filed
after the Closing Date or otherwise) with respect to any tax period ending on
or before the Closing Date relating to the HE Subsidiaries; provided, however,
that (i) Newco, HCS, HCCS and HCJ shall be entitled to retain, or receive
immediate payment from HE of, any such refund or credit to the extent that
such refund or credit arises as a result of the use or application (as
provided in Section 4.03) of any net capital loss, foreign tax credit or
research and development credit of HCS, HCCS or HCJ for any tax year ending on
any date following the Closing Date to any period of HCS, HCCS or HCJ ending
on or before the Closing Date and (ii) to the extent that HE or any of its
affiliates (other than HCS, HCCS and HCJ) would, but for the carryback by HCS,
HCCS or HCJ of any such net capital loss, foreign tax credit or research and
development credit, be entitled to a refund or credit in respect of any net
capital loss, foreign tax credit or research and development credit of HE or
any of HE's affiliates (other than HCS, HCCS and HCJ), HE shall be entitled to
receive immediate payment from Newco of the amount of any such amount to the
extent Newco has previously received a refund or credit from a carryback to
HE's return. Newco and HCS, HCCS and HCJ shall be entitled to retain, or
receive immediate payment from HE of, any refund or credit with respect to
Income Taxes with respect to any taxable period beginning after the Closing
Date relating to HCS, HCCS and HCJ.
 
  4.05 Method of Payment. Unless the parties otherwise agree, all payments by
a party pursuant to this Agreement shall be made by wire transfer to a bank
account designated from time to time by the other party. The paying party
shall also provide a notice of payment to the recipient.
 
  4.06 Interest. If any payment hereunder is not timely paid, interest shall
accrue on the unpaid amount at the applicable federal, state or local rate, as
the case may be, for deficiencies. A payment will be deemed to be timely paid
only if actually received by the payee on or before the due date thereof.
 
  4.07 Cooperation; Document Retention; Confidentiality.
 
  (a) Upon the reasonable request, HE and Newco shall promptly provide (and
shall cause their respective subsidiaries to provide) the requesting party
with such cooperation and assistance, documents and other information, without
charge, as may be necessary or reasonably helpful in connection with (i) the
preparation and filing of any original or amended tax return, (ii) the conduct
of any audit or other examination or any judicial or administrative proceeding
involving to any extent taxes or tax returns within the scope of this
Agreement, or (iii) the verification by a party of an amount payable hereunder
to, or receivable hereunder from, another party. Such cooperation and
assistance shall include, without limitation: the provision on demand of
books, records, documentation or other information relating to any relevant
tax return; the execution of any document that may be necessary or reasonably
helpful in connection with the filing of any tax return by GM, Newco or any

including, without limitation, the execution of powers of attorney and
extensions of applicable statutes of limitations; the prompt and timely filing

make its employees and facilities available on a mutually convenient basis to
facilitate such cooperation.
 
  (b) HE and Newco shall retain or cause to be retained all tax returns, and
all books, records, schedules, workpapers and other documents relating
thereto, until the expiration of all applicable statutes of limitations
(including any waivers or extensions thereof). The parties hereto shall notify
each other in writing of any waivers, extensions or expirations of applicable

party, all tax returns, documents, schedules, workpapers and similar items
made available under this Section 4.03 or otherwise pursuant to this

but no assignment (other than an assignment by HE of its rights and
obligations hereunder to another member of the GM Group to which HE shall have
assigned all of its right, title and interest in and to the Newco capital
stock then owned by HE or a subsidiary thereof) shall relieve any party's
obligations hereunder without the written consent of the other party.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Subsection (a) of Section 145 of the DGCL empowers a corporation to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or
in the right of the corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.
 
  Subsection (b) of Section 145 of the DGCL empowers a corporation to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of
the corporation to procure a judgment in its favor by reason of the fact that
he acted in any of the capacities set forth above, against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection with
the defense or settlement of such action or suit if he acted under similar
standards, except that no indemnification may be made in respect to any claim,
issue or matter as to which such person shall have been adjudged to be liable
to the corporation unless and only to the extent that the Court of Chancery or
the court in which action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnification for such expenses which the Court of Chancery or such other
court shall deem proper.
 
  Section 145 of the DGCL further provides that, to the extent that a director
or officer of a corporation has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in subsections (a) and
(b) of Section 145, or in the defense of any claim, issue or matter therein,
he shall be indemnified against expenses (including attorneys' fees) actually
and reasonably incurred by him in connection therewith; and that
indemnification provided by, or granted pursuant to, Section 145 shall not be
deemed exclusive of any other rights to which those seeking indemnification
may be entitled. Section 145 further empowers the corporation to purchase and
maintain insurance on behalf of any person who is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would have the power to indemnify him against such liabilities under Section
145 of the DGCL.
 
  Article seven of the Registrant's Certificate of Incorporation provides, in
detail, for the indemnification of directors and officers of the Registrant to
the fullest extent permitted under Section 145 of the DGCL. As permitted by
the DGCL, the Registrant's Certificate of Incorporation contains a provision
limiting the liability of directors for breach of fiduciary duty to the
Registrant or its stockholders except to the extent such exemption from
liability or limitation thereof is not permitted under the DGCL as the same
exists or may hereafter be amended.
 
  Under the Reorganization Agreement, all rights to indemnification existing
on September 20, 1996 for officers and directors of the legal entities
comprising Galaxy, PanAmSat or the Registrant as set forth in the
organizational documents of such entities will survive the Reorganization with
respect to matters existing or occurring at or prior to the Closing Date and
shall continue for five years after the Closing Date. Additionally, the
Reorganization Agreement requires that for a period of four years after the
Closing Date, the Registrant will defend and hold harmless each person who
prior to the Closing Date was or became an officer or director of the
 
                                     II-1
<PAGE>
 
legal entities comprising Galaxy, PanAmSat or the Registrant against all
liabilities, and expenses relating thereto, arising out of the fact that such
person was or is an officer or director of such entities or in connection with
their activities in such capacity to the full extent allowable under the
respective organizational documents of such entities as in effect on September
20, 1996 and under the corporate law of the state in which each such
corporation is incorporated, respectively. With certain restrictions, the
Reorganization Agreement also requires the Registrant to, for a period of five
years after the Closing Date, maintain in effect or replace with equivalent
policies the directors' and officers' liability insurance policies maintained
by Galaxy, PanAmSat or the Registrant, as the case may be, with respect to
matters arising before the Closing Date. See "The Reorganization Agreement--
Indemnification."
 
  The Registrant carries policies of insurance which cover the individual
directors and officers of the Registrant for legal liability and which would
pay on behalf of the Registrant for expenses of indemnification of directors
and officers in accordance with the Certificate of Incorporation.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted for directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant
has been advised that, in the opinion of the Commission, such indemnification
is against public policy as expressed in the Securities Act and is, therefore
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by directors, officers and controlling persons of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
directors, officers and controlling persons in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
competent jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

ITEM 22. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes as follows:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to the Registration Statement:
 
      (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of this registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the Registration Statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20 percent change
    in the maximum aggregate offering price set forth in the "Calculation
    of Registration Fee" table in the effective Registration Statement;
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement;
 
                                     II-7
<PAGE>
 
    (2) That, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof;
 
    (3) To remove from the registration by means of a post-effective
  amendment any of the securities being registered which remain unsold at the
  termination of the offering;
 
    (4) That, for purposes of determining any liability under the Securities
  Act, each filing of the Registrant's annual report pursuant to section
  13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of
  an employee benefit plan's annual report pursuant to section 15(d) of the
  Exchange Act) that is incorporated by reference in this Registration
  Statement shall be deemed to be a new registration statement relating to
  the securities offered herein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof;
 
    (5) To deliver or cause to be delivered with the prospectus, to each
  person to whom the prospectus is sent or given, the latest annual report to
  security holders that is incorporated by reference in the prospectus and
  furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule
  14c-3 under the Exchange Act; and, where interim financial information
  required to be presented by Article 3 of Regulation S-X are not set forth
  in the prospectus, to deliver, or cause to be delivered to each person to
  whom the prospectus is sent or given, the latest quarterly report that is
  specifically incorporated by reference in the prospectus to provide such
  interim financial information;
 
    (6) That prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this Registration
  Statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other Items
  of the applicable form;
 
    (7) That every prospectus (i) that is filed pursuant to paragraph (6)
  immediately preceding or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Securities Act and is used in connection with an
  offering of securities subject to Rule 415, will be filed as a part of an
  amendment to this Registration Statement and will not be used until such
  amendment is effective, and that, for purposes of determining any liability
  under the Securities Act, each such post-effective amendment shall be
  deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof;
 
    (8) That insofar as indemnification for liabilities arising under the
  Securities Act may be permitted to directors, officers and controlling
  persons of the Registrant pursuant to the foregoing provisions, or
  otherwise, the Registrant has been advised that in the opinion of the
  Securities and Exchange Commission such indemnification is against public
  policy as expressed in the Securities Act as is, therefore, unenforceable.
  In the event that a claim for indemnification against such liabilities
  (other than the payment by the Registrant of expenses incurred or paid by a
  director, officer or controlling person of the Registrant in the successful
  defense of any action, suit or proceeding) is asserted by such director,
  officer or controlling person in connection with the securities being
  registered, the Registrant will, unless in the opinion of its counsel the
  matter has been settled by controlling precedent, submit to a court of
  appropriate jurisdiction the question whether such indemnification by it is
  against public policy as expressed in the Securities Act and will be
  governed by the final adjudication of such issue;
 
    (9) To respond to requests for information that is incorporated by
  reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this
  form, within one business day of receipt of such request, and to send the
  incorporated documents by first class mail or other equally prompt means.
  This includes information contained in documents filed subsequent to the
  effective date of the Registration Statement through the date of responding
  to the request;
 
    (10) To supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in the Registration Statement when
  it became effective.

Ladies and Gentlemen:

          We are acting as counsel to Magellan International, Inc., a Delaware
corporation (the "Company"), in connection with the Registration Statement on
Form S-4 (the "Registration Statement") for the registration of up to a maximum
of 59,522,189 shares of common stock of the Company, par value $.01 per share
(the "Shares"), under the Securities Act of 1933, as amended (the "Act").  As
such counsel, we have been requested to render this opinion as to the matters
set forth below.

          In connection with rendering the opinion set forth herein, we have
been furnished with and examined such documents, corporate records and
instruments, as we have deemed necessary or appropriate for purposes of
expressing the opinion contained herein.

          In our examination we have assumed, without investigation, the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals and the conformity to original documents of all documents submitted
to us as copies.  In rendering our opinion, we have relied as to factual matters
upon information obtained from the Company, its officers and representatives, 
and we have assumed that the Class A Common Stock and Common Stock of PanAmSat
Corporation is, and at the time of exchange for the Shares in the manner
contemplated by the Registration Statement will be, validly issued, fully paid
and nonassessable.

          We are members of the Bar of the State of New York, and we express no
opinion hereunder except under the General Corporation Law of the State of
Delaware.

          Subject to the foregoing, it is our opinion that the Shares have been
duly authorized, and, upon issuance and delivery in the manner contemplated by
the Registration Statement, will be validly issued, fully paid and
nonassessable.

          We hereby consent to your filing this opinion as an exhibit to the
Registration Statement and to the reference to our firm contained under the

Dear Sirs:

          You have requested our opinion concerning the qualification of the
merger described below as a tax-free exchange pursuant to Section 351 of the
Internal Revenue Code of 1986 (the "Code").

          For the purposes of rendering this opinion, we have reviewed the
following documents:

          1.   Agreement and Plan of Reorganization among Hughes Communications,
     Inc. ("HCI"), Hughes Communications Galaxy, Inc. ("Galaxy"), Hughes
     Communications Satellite Services, Inc., Hughes Communications Services,
     Inc., Hughes Communications Carrier Services, Inc., Hughes Communications
     Japan, Inc., Magellan International, Inc. ("New PanAmSat") and PanAmSat
     Corporation ("PanAmSat"), dated September 20, 1996 (the "Reorganization
     Agreement");

          2.  Stock Contribution and Exchange Agreement among Grupo Televisa,
     S.A. ("Televisa"), Satellite Company, LLC

     ("S Company"), New PanAmSat, and PanAmSat, dated September 20, 1996 (the
     "Exchange Agreement");

          3.  The DTH Option Purchase Agreement among PanAmSat, Televisa and S
     Company, dated September 20, 1996.

          4.  Principal Stockholders Agreement among HCI, Galaxy, the holders of
     PanAmSat Class A Common Stock (the "Class A Holders"), Univisa Satellite
     Holdings, Inc. ("USHI") and S Company, dated September 20, 1996 (the
     "Principal Stockholders Agreement");

          5.  The form of Stockholder Agreement among New PanAmSat, HCI, the
     Class A Holders and S Company pursuant to the Reorganization Agreement (the
     "Stockholder Agreement");

          6.  Draft of Agreement and Plan of Merger dated as of April 4, 1997
     (the "Merger Agreement"); and

          7.  The PanAmSat Proxy Statement/Magellan International, Inc.
     Prospectus, dated April 16, 1997, for a special meeting of Stockholders to
     be held on May 8, 1997 (the "Proxy Statement").

          In addition, we have made such investigations of law and fact as we
have deemed appropriate for the purpose of rendering the opinion set forth
below. Based on the foregoing, our understanding of the facts is set forth
below.

          PanAmSat is a Delaware corporation.  Currently, PanAmSat has
outstanding three classes of common shares -- Class A Common Stock, Class B
Common Stock and Common Stock, and a single class of preferred stock.  The Class
A Common Stock, of which 21,231,415 shares are outstanding, is held primarily by
members of the Anselmo family and trusts for their benefit.  The Class B Common
Stock, of which 40,459,431 shares

PanAmSat Corporation                  -3-                       April 16, 1997


are outstanding, is held by USHI, a wholly-owned Delaware subsidiary of Univisa,
Inc., the shares of which, in turn, are wholly-owned by S Company, a Nevada
limited liability company. S Company, in turn, is wholly owned by Televisa, a
Mexican corporation. The Common Stock of PanAmSat, of which 38,320,774 shares
are outstanding (as of April 8, 1997), is publicly-traded. Each share of
Class A Common Stock and Class B Common Stock is convertible into one share of
Common Stock./1/

          HCI, a California corporation, is a wholly-owned subsidiary of Hughes
Telecommunications and Space, Inc., which in turn is a wholly-owned subsidiary
of Hughes Electronics Corporation; and they are included in consolidated federal
income tax returns filed by an affiliated group of which General Motors
Corporation is the common parent.  Through a number of direct and indirect
wholly-owned subsidiaries (the "Contributed Entities"), HCI engages in the
business of

providing satellite services and capacity (the "Galaxy Business").

          New PanAmSat is a newly-organized Delaware corporation and a wholly-
owned subsidiary of HCI.  Currently, New PanAmSat is not engaged in any
business.

          Pursuant to the Reorganization Agreement, the following transactions
will occur at the closing (the "Closing"):

          1.  HCI will transfer to New PanAmSat the assets, subject to
     liabilities, associated with the Galaxy Business (including the stock of
     the Contributed Entities) in exchange for shares of New PanAmSat Common
     Stock.

          2.  Pursuant to the Exchange Agreement, S Company will transfer all of
     its shares in Univisa to New PanAmSat in exchange for (at the election of S
     Company), (i) one share of New PanAmSat Common Stock, (ii) one-half share
     of New PanAmSat Common Stock and one-half of the Standard Cash
     Consideration (as described below); or (iii) the Standard Cash
     Consideration.

          3.  New PanAmSat will organize a wholly-owned Delaware subsidiary
     ("PAS Merger Corp.").  Pursuant to the Reorganization Agreement, PAS Merger
     Corp. will be merged with and into PanAmSat, with PanAmSat as the surviving
     corporation.  In the merger, each share of PanAmSat Class 
<PAGE>
 
PanAmSat Corporation                  -5-                       April 16, 1997


     A Common Stock and Common Stock will be converted into the right to receive
     (at the election of the stockholder made prior to the Closing Date), one of
     the following:

               (i) one share of New PanAmSat Common Stock (subject to proration
          if the amount of stock elected exceeds a certain threshold);

               (ii) one-half share of New PanAmSat Common Stock and one-half of
          the Standard Cash Consideration (as defined below); or

               (iii) the Standard Cash Consideration (subject to proration if
          the amount of cash elected exceeds a certain threshold).

          The Standard Cash Consideration is $30 per share, except that if the
Closing does not occur on or prior to September 20, 1997, then the Standard Cash
Consideration shall be increased at a rate equal to 9% per annum for the period
commencing on September 20, 1997 and ending on the Closing Date.

          Immediately after S Company receives the consideration described in 3
above, New PanAmSat will repurchase 7.5 million of the shares of its Common
Stock issued to S Company in exchange for $225 million in cash.  Substantially
concurrently with receiving payment for such shares, Televisa, S Company and/or
one or more of their designees (at Televisa's election) will, pursuant to the
terms

PanAmSat Corporation                  -6-                       April 16, 1997


of the DTH Option Purchase Agreement, purchase the DTH Option (as defined
in such agreement) for $225 million in cash.

          The foregoing transactions will occur on the same day at a
simultaneous closing.  Assuming that, under steps 2 and 3 described above the
maximum amount of cash consideration is paid under the Exchange Agreement and in
the merger, the ownership of New PanAmSat stock immediately after the closing
will be as follows:

PanAmSat Common Stock Holders
</TABLE>

          Pursuant to the Principal Stockholders Agreement, the Class A Holders
and S Company may not transfer, prior to the Closing, any PanAmSat shares or
interests therein except for up to an aggregate of 2,500,000 shares each, unless
they mutually agree and certain other conditions are met (in which event the
maximum amount of shares that each can transfer cannot exceed 5 million).
Pursuant to the Stockholder Agreement, HCI, the Company, the Class A Holders and
S Company will be subject to restrictions on the sale, issuance or other
disposition of New PanAmSat shares.  During a period after the Closing measured
by the shorter of one year and the completion by the Company of 
<PAGE>

the refinancing of up to $1.5 billion of indebtedness incurred in connection
with the transactions effected pursuant to the Reorganization Agreement and the
Exchange Agreement, only the Company will be permitted to sell New PanAmSat
shares, and only for the purpose of effecting such refinancing (except that the
Company may make reasonable issuances for such purposes as employee plans and
acquisitions); provided, that the Class A Holders and S Company will be
permitted during such period to sell their New PanAmSat shares to certain
permitted transferees and in private transactions with the reasonable consent of
HCI. For a period of one year after such exclusive period for sales by the
Company ends, the Class A Holders and S Company, but not HCI or the Company
(except for such purposes as employee plans and acquisitions) will be permitted
to sell New PanAmSat shares. The parties are considering amending the
Stockholder Agreement after the Closing to modify the sale restrictions,
including permitting the Class A Holders and S Company to sell shares of New
PanAmSat stock during the one-year period beginning on the Closing Date. With
your permission, we have assumed that there will not exist at the time of the
Closing any contract or other binding commitment on the part of the Class A
Holders, HCI or S Company to dispose of their shares of Common Stock of New
PanAmSat (except as described above with respect to the DTH Option).

          Our opinion relates to the qualification of the New PanAmSat merger as
a tax-free exchange under Section 351 of the Code.  Under paragraph (a) of that
section, no gain or loss is recognized if property is transferred to a
corporation by one or more persons in exchange for stock of the corporation and
immediately after the exchange such person or persons are in control of the
corporation.  This non-recognition rule applies both to the transferors and to
the transferee corporation.  Under paragraph (b) of that section, if in addition
to stock of the transferee corporation money or other property is received in
the transaction by the property transferor, gain is recognized by the
transferor, but only to the extent of the amount of money and the fair market
value of other property received in the exchange.

          In Rev. Rul. 67-448, 1967-2 C.B. 144, P formed S, a wholly-owned
subsidiary, solely for the purpose of facilitating the acquisition of all of the
stock of T by merger.  In the merger, T was the surviving corporation, S stock
held by P was converted into 100% of the outstanding T stock and the T
stockholders received voting stock of P in exchange for their T stock.  Because
its existence was transitory, the Internal Revenue Service disregarded the
existence of S and treated the transaction as the acquisition by P of all of the
stock of T 
<PAGE>
 
PanAmSat Corporation                  -9-                       April 16, 1997


from its stockholders for voting stock, which acquisition qualified as a
reorganization under Section 368(a)(1)(B).

          Rev. Rul. 67-448 pre-dates the enactment of Code Section 368(a)(2)(E),
which permits a so-called "reverse subsidiary merger" to qualify as a
reorganization under Section 368(a)(1)(A) in certain circumstances.  However,
Rev. Rul. 67-448 continues to apply in cases where Section 368(a)(2)(E) is
inapplicable.  See, e.g., Rev. Rul. 74-564, 1974-2 C.B. 124, where grandparent
stock was used in a reverse merger involving a transitory subsidiary, thus
disqualifying the transaction under section 368(a)(2)(E), but qualifying it
under section 368(a)(1)(B).

          The rationale of Rev. Rul. 67-448 has been extended to situations
outside of the reorganization context.  For example, where the consideration
received by the T stockholders in the reverse merger is cash, the IRS has held
that the transaction should be treated as the purchase of T stock by P for cash.
See, e.g., Treas. Reg. (S) 1.338-2(b)(2), Example (2).  The IRS has also

extended this rationale to qualify

transactions as tax-free exchanges under section 351. See, e.g., LTR 8912024
(December 22, 1988)./2/

          On the basis of the foregoing, the merger transaction should be
treated as the transfer by the holders of the Class A Common Stock and Common
Stock of their shares to New PanAmSat in exchange for the merger consideration -
- - either shares of New PanAmSat Common Stock, cash or both.

          Contemporaneously with this transfer, HCI and S Company will also
transfer property to New PanAmSat in exchange for New PanAmSat Common Stock and,
in the case of S Company, cash.

          Section 351 applies if "one or more transferors" transfer property to
a corporation and immediately after the exchange the transferors "control" the
corporation.  For this 



- ------------------
/2/ In this ruling, the reverse merger was used to establish a holding company
structure.  T organized a subsidiary P, which in turn organized a second
subsidiary S.  S merged into T, with T surviving, and the T common stock was
converted into P common stock, with the result that T became a subsidiary of P.
In the merger, however, outstanding preferred stock of T remained outstanding,
so that P was not viewed as acquiring control of T.  This disqualified the
transaction under both sections 368(a)(1)(B) and 368(a)(2)(E).  The Service
ruled that the exchange qualified under section 351 as a transfer of the common
stock of T by the T stockholders to P in exchange for all of the stock of P.

purpose, "control" means ownership of stock possessing at least 80% of the total
combined voting power of all classes of stock entitled to vote and at least 80%
of all other classes of stock. In the present transaction, HCI, S Company and
the holders of the PanAmSat Class A Common Stock and Common Stock receiving
shares of New PanAmSat in the merger will each be "transferors," and immediately
after the transfer they will together own 100% all of the outstanding shares of
New PanAmSat.

          Based upon the foregoing, it is our opinion that:

          1.  The transfer of the Class A Common Stock and the Common Stock
     pursuant to the Merger will be a transfer described in section 351 of the
     Code.

          2.  Each holder of Class A Common Stock or Common Stock that receives
     solely New PanAmSat Common Stock will not recognize gain or loss as a
     result of the Merger.

          3.  Each holder of Class A Common Stock or Common Stock that receives
     solely cash consideration will recognize gain or loss equal to the
     difference between the cash consideration (which will include any increase
     in merger consideration as a result of the Closing occurring after
     September 20, 1997) and the tax basis of such holder's shares.  Such gain
     or loss, if any, will be long-term capital gain or loss if such Class A
     Common Stock or

     Common Stock constitutes a capital asset to such holder and was held for
     more than one year at the time of the Closing.

          4.  Subject to the discussion below concerning fractional shares, each
     holder of Class A Common Stock or Common Stock who receives both cash
     consideration and New PanAmSat Common Stock will recognize gain measured by
     the lesser of (i) the excess, if any, of (x) the sum of the fair market
     value (at the effective time of the Merger) of the New PanAmSat Common
     Stock and cash consideration received by such holder over (y) the aggregate
     tax basis of such holder's shares of Class A Common Stock or Common Stock,
     and (ii) the cash consideration (which will include any increase in merger
     consideration as a result of the Closing occurring after September 20,
     1997) received by such holder (not including any cash received in lieu of
     fractional shares as discussed below).  Such gain, if any, will be long-
     term capital gain if such Class A Common Stock or Common Stock constitutes
     a capital asset to such holder and was held for more than one year at the
     time of consummation of the Merger.  A loss would not be recognized by such
     holder.

          5.  A holder who holds more than one block of Class A Common Stock or
     Common Stock (i.e., shares acquired at 
<PAGE>

     different times or prices) who receives both cash consideration and New
     PanAmSat Common Stock will determine the amount of gain recognized and loss
     not recognized pursuant to the Merger separately with respect to each such
     block of stock. For this purpose, all of the cash consideration and New
     PanAmSat Common Stock received by a holder of Class A Common Stock or
     Common Stock will be allocated proportionately among the blocks of Class A
     Common Stock or Common Stock surrendered by such holder.

          6.  The aggregate tax basis of the shares of New PanAmSat Common Stock
     received by PanAmSat's stockholders, including the fractional shares deemed
     to be received (as discussed below), will be the same as the aggregate tax
     basis of the shares of Class A Common Stock and the Common Stock exchanged
     therefor (i) increased by the gain recognized (as calculated above) and
     (ii) decreased by the cash consideration received (other than cash received
     in lieu of fractional shares).

          7.  The holding period of the shares of New PanAmSat Common Stock
     received in the Merger will include the holding period of the shares of
     Class A Common Stock or Common Stock surrendered therefor, assuming the
     shares constitute a capital asset to the holder.

          8.  PanAmSat stockholders who receive cash in lieu of fractional
     shares of New PanAmSat Common Stock will be treated as having received such
     fractional shares pursuant to the Merger and then as having sold those
     fractional shares in the market for cash.  See Rev. Rul. 66-365,1966-2 C.B.
     116.  Such stockholders will recognize gain or loss with respect to such
     fractional shares in an amount equal to the difference between the tax
     basis allocated to such fractional shares (as calculated above), and the
     cash received in respect thereof.  Any such gain or loss will be capital
     gain or loss and will constitute long-term capital gain or loss (assuming
     the shares constitute a capital asset to the holder)  if the holding period
     of the Class A Common Stock and the Common Stock in exchange for which such
     fractional shares are deemed issued (as determined above) exceeds one year.

     transact the business it transacts and to otherwise enter into and perform
     its obligations under each Operative Document to which it is or will be a
     party.  Such Lessee is duly qualified to do business as a foreign
     corporation and in good standing in each jurisdiction wherein the failure
     to do so would have a material adverse effect, in the case of STLC, on the
     conduct of its business and operations as presently conducted or on the
     ability of STLC to perform its obligations under the Operative Documents
     and Hughes Agreements to which it is a party and, in the case of GMHE, on
     the financial condition or operations of GMHE and its subsidiaries taken as
     a whole or on the ability of GMHE to perform its obligations under the
     Operative Documents and Hughes Agreements to which it is a party.

     execution and delivery thereof, nor the consummation by it of the
     transactions contemplated thereby (including, without limitation,

     the operation of the Transponders), nor compliance by such Lessee with any
     of the terms and provisions thereof (i) requires any approval of
     stockholders or approval or consent of any trustee or holders of any of its
     indebtedness or obligations; (ii) contravenes any law, judgment,
     governmental rule or regulation or order applicable to or binding on it or
     any of its properties, the contravention of which would have a material
     adverse effect on the conduct of its business and operations as presently
     conducted or the performance of its obligations under the Operative
     Documents and the Hughes Agreements to which it is a party; (iii)
     contravenes or results in any breach of, or constitutes any default under,

     contract, bank loan or credit agreement for borrowed money, contract or
     other agreement or instrument to which it is a party or by which it or any
     of its properties may be bound or affected, the contravention, breach or
     default of which would have a material adverse effect on the conduct of its
     business and operations as presently conducted or the performance of its
     obligations under the Operative Documents and the Hughes Agreements to
     which it is a party; (iv) contravenes its corporate charter or by-laws; or
     (v) results in the creation of any Lien (other than Permitted Liens
     described in clauses (a) and (b) of the definition thereof) upon the
     Transponders or any material property of such Lessee.

          (c)  Neither the execution and delivery by it of the Operative
     Documents or Hughes Agreements to which it is or will be a party, nor the
     consummation by it of any of the transactions (including, without
     limitation, the operation of the Transponders) contemplated thereby,
     requires the consent, approval or authorization of, the giving of notice
     to, or the registration with, the recording or filing of any document with,
     or the taking of any other action in respect of, any Governmental Body,
     except (i) such of the foregoing as have been obtained, given or done, (ii)
     the filings and actions described in clause (ii) of Section 4.01(g), and

     requires any official action or determination by the FCC as of the Delivery
     Date, is subject to approval or disapproval by the FCC or as of the
     Delivery Date gives rise to a right by any third party to file a petition
     to deny.

          (d)  Each Operative Document and Hughes Agreement to which such Lessee
     is a party constitutes the legal, valid and binding obligation of such
     Lessee, enforceable against such Lessee in accordance with its terms,
     except as such enforcement may be subject to bankruptcy, insolvency,
     moratorium or other similar laws affecting creditors' rights generally and
     to general principles of equity.

          (e)  Except as disclosed in writing to Indenture Trustee, Owner
     Trustee, Owner Participant and Initial Note Purchaser prior to the
     execution of this Agreement, there are no actions, suits or proceedings
     pending against such Lessee in any court or before any arbitrator of any
     kind or before or by any Governmental Body, or to the knowledge of such
     Lessee threatened, which question the legality or validity of any of the
     Operative Documents or Hughes Agreements to which such Lessee is a party or
     the transactions contemplated thereby or which, individually or in the
     aggregate, if adversely determined, would have a material adverse effect in
     the case of STLC, on the conduct of its business and operations as
     presently conducted or on the ability of STLC to perform its obligations
     under the Operative Documents or the Hughes Agreements to which it is a
     party and, in the case of GMHE, on the financial condition or operations of
     GMHE and its subsidiaries taken as a whole or on the ability of GMHE to
     perform its obligations under the Operative Documents and Hughes Agreements
     to which it is a party.

          (f)  Such Lessee is not in violation of any Order of any Governmental
     Body, which violation would have a material adverse effect on the conduct
     of its business and operations as conducted on the date hereof.

          (g)  On the Delivery Date, upon delivery of the Bill of Sale to Owner
     Trustee and payment of Buyer's Cost for the Transponders by Owner Trustee
     to Seller (i) Seller will deliver to Owner Trustee good and marketable

     the definition thereof and (ii) except for the filing of a Uniform

     Estate and naming Owner Trustee as debtor and Indenture Trustee as secured

     Indenture Trustee for filing or recording), and except for the taking by
     Indenture Trustee of possession of the executed original counterpart of the
     Lease, no further action, including any filing or recording of any
     document, is necessary or advisable in order to establish, confirm and
     protect Owner Trustee's right, title and interest in and to the
     Transponders or to perfect for the benefit of the Noteholders the security
     interest in the Indenture Estate provided for in the Indenture (other than

     than such approvals or consents as have been obtained or will have been
     obtained prior to the Delivery Date; (ii) contravenes any law, judgment,

     above, except as may otherwise be noted therein, and in the opinion of
     management reflect all adjustments which are necessary for a fair

     change in GMHE's consolidated financial condition, operations, business or

     amount of funds available to Owner Trustee and will otherwise cause Owner
     Trustee to perform its obligations under such Section 8(a) or 8(c) in
     accordance with the terms thereof.

          (k)  Notice of Indenture Event of Default.  Promptly after Owner

under the Indenture in respect of such Notes by giving notice of such election
in its notice given pursuant to Section 19(b) of the Lease, in accordance with,
subject to the conditions of and with the effect provided in Section 2.13 of the

permitted by Applicable Law, be subrogated to any right of such Indemnitee in
respect of the matter against which such indemnity has been paid to the extent
of such payment.  Owner Trustee shall be subrogated to any rights of Indenture
Trustee or the holder of any Note (other than any security interest) to the
extent any amount otherwise payable to Owner Trustee under the Indenture shall
be reduced by the failure of such Lessee to have paid any indemnity to Indenture
Trustee or such Noteholder.

          (b)  Without limitation of the foregoing, Lessees jointly and
severally shall pay on an After-Tax Basis (except to the extent such amounts are

Indenture Trustee to the provisions of the Indenture.

and, at such Indemnitee's request, shall assume the defense thereof with counsel
reasonably acceptable to such Indemnitee.  Such Indemnitee shall fully cooperate
with such Lessee in all ways reasonably requested by such Lessee in said defense
by such Lessee.  In any such action, any Indemnitee shall have the right to
employ separate counsel in such action and participate therein, subject to the
preceding sentence, but the fees and expenses of such counsel shall be at the
expense of such Indemnitee, unless (i) the employment of such counsel has been
specifically authorized by either Lessee, (ii) the named parties to such action
(including any impleaded parties) include both such Indemnitee and one or both
Lessees and representation of such Indemnitee and such Lessee(s) by the same
counsel would be unethical under the applicable standards of professional
conduct due to actual or potential conflicting interests between them, (iii)
such action involves an act that involves or is alleged to involve criminal
activity undertaken in compliance with or as contemplated by the Operative
Documents or Hughes Agreements or involves the risk of criminal penalties,
unless such action does not lead to the commencement (including, without
limitation, the impanelling of a grand jury or similar investigatory proceeding)
of a criminal proceeding.  Lessees shall not be liable for any settlement of any
action, suit, proceeding or claim effected without their written consent and no
Indemnitee will agree to any such settlement without the prior written consent
of Lessees.

          (d)  Notwithstanding the provisions of the immediately preceding
paragraph, the omission by any Indemnitee to notify any Lessee of any Expense
shall not relieve such Lessee from any liability which it may have hereunder in
respect of any such Expense or other Expense; provided, however, that nothing

herein contained shall prevent such Lessee from bringing a subsequent action
against such Indemnitee for damage suffered by such Lessee as a result of such
omission.

of an Indemnitee by a Lessee pursuant to this Section 6.01, such Indemnitee

taken into account in computing such payment, such Indem nitee shall promptly
pay to such Lessee (but only if Lessees shall have made all payments then due
and owing to such Indemnitee under the Operative Documents), an amount equal to
the sum of (I) the actual reduction in Taxes realized by such Indemnitee which
is attributable to such deduction or credit, and (II) the actual reduction in
Taxes realized by such Indemnitee as a result of any payment made by such
Indemnitee pursuant to this sentence; provided, however, that such Indemnitee

shall not be obligated to make any payment to any Lessee pursuant to this
sentence if and for so long as a Payment Default, Bankruptcy Default or any
Event of Default shall have occurred and be continuing, but shall promptly make
such payment once all such Events of Default shall no longer be continuing; and
provided, further, however, that such Indemnitee shall not be obligated to make
- --------  -------  -------                                                     
any payment pursuant to this Section 6.01 to the extent that the amount

calculated pursuant to (I) above would exceed (x) the amount of all prior
payments received by such Indemnitee from such Lessee pursuant to this Section
                                                                       -------

computed pursuant to (I) above paid by such Indemnitee to such Lessee hereunder.
Any Taxes that are imposed on any Indemnitee as a result of a disallowance or
reduction of any tax benefit taken into account in the prior sentence shall be
treated as a Tax for which Lessees are obligated to indemnify such Indemnitee
pursuant to the provisions of Article VII hereof without regard to Section 7.02

          Except as expressly provided in this Agreement or in any other
Operative Document, Lessee shall not be liable to any Indemnitee for incidental

     transactions contemplated by the Operative Documents or the Hughes
     Agreements (unless such failure results from a Lessee's failure to provide
     timely notice of the requirement of such filing or the failure by a Lessee
     to provide information reasonably required in connection with such filing),
     of any Indemnitee or any Affiliate thereof, or any successor, assign,

     failure to act required or contemplated under any of the Operative
     Documents or Hughes Agreements); (ii) that is imposed on any Indemnitee to

     such Indemnitee; (iii) that is imposed on any Indemnitee as a result of a
     claim unrelated to the transaction contemplated herein; (iv) that is
     imposed on Owner Participant, Owner Trustee or Lessor's Estate because of
     or in connection with any Owner Participant or Lessor Lien, respectively;

     Lease;

          (i)  any penalties, fines, additions to Tax and interest (I) resulting
     from matters contemplated by the Operative Documents or the Hughes
     Agreements in the case where an Indemnitee has notified Lessees that it
     intends to file a return in accordance with Section 7.05 and files a return

     in a manner materially inconsistent with such notice and as a result of
     such filing Lessees' ability to contest is materially impaired (such
     impairment to include, for purposes of this Section 7.02(i), the fact, if
     applicable, that Lessees elected to waive their contest rights in respect
     of such filing on the basis of the information provided by Indemnitee to
     Lessees in such notice), or (II) to the extent not attributable to a Tax
     indemnified against hereunder;

     Noteholder pursuant to the Indenture but only to the extent that Owner
     Trustee or such Noteholder has been made whole on an After-Tax Basis; and

          (k)  any Tax to the extent such Tax (i) would have been imposed on an
     Indemnitee had it not engaged in activities related to the transaction
     contemplated herein, or (ii) is imposed by any United States jurisdiction
     that would not have imposed such Tax on the Indemnitee but for activities

     Participant) in such jurisdiction unrelated to the transactions
     contemplated herein;

Tax Indemnification Agreement shall control and no payments shall be made under
this Article VII.  Notwithstanding anything to the contrary contained in this
     -----------                                                              
Section 7.02, the exceptions set forth in this Section 7.02 shall not apply,

with respect to the Owner Trustee, the Owner Participant or the Lessor's Estate,

premium on the Notes or imposed by reason of any failure to withhold with
respect to such payments.

          Section 7.03.  Calculation of Indemnity Payments.  If any Indemnitee
                         ---------------------------------                    
subsequently realizes a tax benefit by reason of any payment of an indemnified
Tax pursuant to this Article VII, which benefit had not previously been taken

into account in computing such payment, such Indemnitee shall pay Lessees when
such tax benefit is actually utilized (but not before Lessees shall have made
all payments and indemnification theretofore due to such Indemnitee pursuant to
the Operative Documents) an amount equal to the lesser of (a) the sum of (i) an
amount equal to such tax benefit, plus (ii) an amount equal to any other tax
benefit realized and actually utilized by such Indemnitee as the result of any
payment made by such Indemnitee pursuant to this sentence, and (b) the amount of
such payment by Lessees to such Indemnitee and any other payment by Lessees to
such Indemnitee theretofore made pursuant to this Article VII with respect to

such Tax, reduced by other amounts previously paid by such Indemnitee to Lessees
pursuant to

this Article VII; provided, however, that notwithstanding the foregoing 
     -----------  --------  -------      
portions of this sentence, such Indemnitee shall not be obligated to make any
payment to Lessees pursuant to this sentence if and for so long as an Event of
Default shall have occurred and be continuing, but shall promptly make such
payment once all Events of Default shall no longer be continuing; it being
intended that such Indemnitee should not realize a net tax benefit pursuant to
this Article VII unless Lessees shall first have been made whole for any 
     -----------                                          
payments by it to such Indemnitee pursuant to this Article VII.  Any Taxes that 
                                                   -----------  
are imposed on any Indemnitee as a result of a disallowance or reduction of any
tax benefit taken into account in the prior sentence shall be treated as a Tax
for which Lessees are obligated to indemnify such Indemnitee pursuant to the
provisions of Article VII hereof without regard to Sections 7.02 (other than 
              -----------                                       
subsections (f) and (g) thereof) and 7.04.

          Section 7.04.  Contest.  (a)  If a claim shall be made against any
                         -------                                            
Indemnitee for any Tax in excess of $10,000 for which Lessees would be obligated
to indemnify pursuant to this Article VII, such Indemnitee shall promptly notify
                              -----------                                       
Lessees after such Indemnitee becomes aware of such action and in any event
within 30 days after receipt by such Indemnitee of a written claim (but failure
to notify Lessees within such 30-day period shall not impair such Indemnitee's
right to indemnification under this Article VII except to the extent that
                                    -----------                          
Lessees' rights to contest such claim shall have been materially impaired by
such failure) and shall, to the extent permitted by applicable law, not pay the
claim before the earlier of (i) 30 days after giving Lessees notice, and (ii)
receipt of Lessees' response.  If either Lessee shall so request within 30 days
after receipt of such notice, such Indemnitee shall, at Lessees' expense
reimbursed to such Indemnitee on an After-Tax Basis, contest the imposition,
validity or applicability of such Tax. The ultimate control over the conduct of
such contest (including the right to forego any and all administrative appeals,
proceedings, hearings and conferences in respect of such claim and the right to
select the forum for such contest and determine whether any such contest shall
be by (i) resisting payment of such Tax, (ii) paying such Tax under protest or
(iii) paying such Tax and seeking a refund thereof) shall remain with such
Indemnitee; provided, however, that such Indemnitee shall keep Lessees or their 
            --------  -------                                 
counsel reasonably informed as to the progress thereof, consult
with Lessees within a reasonable period before any significant action with
respect thereto is taken or omitted and consider in 

                                      53
<PAGE>
 
good faith any suggestions made by Lessees or their counsel; provided, further,

that, for so long as there shall not have been a Bankruptcy Default nor shall
Owner Participant have exercised any of its remedies pursuant to Section 16 of
the Lease, no such proceedings or litigation shall be settled or otherwise
compromised without the prior written consent of Lessees.  If such Indemnitee so
elects, such contest shall be conducted by Lessees in the name of such
Indemnitee (subject to the preceding proviso) and in no event shall such
Indemnitee be required or Lessees be permitted to contest or to continue to
contest, as the case may be, the imposition of any Tax for which Lessees are
obligated to indemnify pursuant to this Article VII unless (A) Lessees shall
                                        -----------
have agreed to pay such Indemnitee on demand and shall have paid as so demanded
all reasonable costs and expenses that such Indemnitee may incur in connection
with contesting such claim (including, without limitation, all costs, expenses,
losses, reasonable legal and accounting fees and disbursements) on an After-Tax
Basis; (B) such Indemnitee shall have determined in good faith that the action
to be taken will not result in any material danger of sale, forfeiture or loss
of any Transponder or any part thereof or any interest therein (except if
Lessees shall have made provision to protect the interests of such Indemnitee in
a manner satisfactory to such Indemnitee); and (C) if such contest shall be
conducted in a manner requiring the payment of the claim, Lessees shall have
advanced on an interest-free basis an amount equal to the amount of such claim
which such Indemnitee shall have elected to pay and Lessees shall have
indemnified the Indemnitee in a manner satisfactory to the Indemnitee, for any
adverse tax consequences from the receipt, or interest-free nature, of such
advance.  If, following a Lessee's exercise of its contest rights pursuant to
Section 7.04 hereof, there is a final determination adverse to Indemnitee and 
- ------------                         
Lessees and an Indemnitee dispute such Lessee's indemnity obligations hereunder
with respect to such final determination, all fees and expenses incurred during
such lawsuit by the prevailing party will be paid or reimbursed, on an After-Tax
Basis, by the losing party.

          (b)  An Indemnitee may at any time elect to decline to take any action
or any further action with respect to a proposed claim or contest; provided,
                                                                   --------

this Article VII, such Indemnitee shall notify Lessees that it waives its right

by an Indemnitee to decline to take any action or take any further action with
respect to a proposed claim or contest for any given taxable period shall not
affect the rights and obligations of any other Indemnitee with respect to such
proposed claim.  An election by an Indemnitee to decline to take any action with
respect to a proposed claim or contest shall not affect the rights and
obligations of such Indemnitee and Lessees hereunder in respect of any other
taxable period or any other taxing authority unless such election not to contest
materially impairs as a legal or practical matter the ability of Lessees or an
Indemnitee to contest any Tax for which such Indemnitee is indemnified pursuant
to this Article VII.  Upon any such election by an Indemnitee if Lessees shall 
        -----------   
have advanced an amount to an Indemnitee pursuant to clause (C) of this Section
                                                                        -------

benefit realized by such Indemnitee as a result of the repayment of such
advance; such repayment shall be made upon the occurrence of the earlier of (x)
final adjudication of such contest (including a settlement thereof) and (y) such
time as such Indemnitee shall elect to discontinue the contest as above
provided; provided, however, notwithstanding the foregoing, such Indemnitee
          --------  -------                                                 
shall not be obligated to make any repayment to Lessees pursuant to this
sentence for so long as an Event of Default shall have occurred and be
continuing but shall promptly make such payment once all Events of Default shall

                          --------------------------------------------       
Lessee and each of Owner Participant, Initial Note Purchaser, Owner Trustee and
Indenture Trustee agrees to effectuate the resale of the Notes in a transaction
in accordance with Rule 144A under the Securities Act ("Rule 144A") and the
reset of the interest rate on the Notes in connection with such resale, as soon
as commercially feasible after the Delivery Date on the terms and subject to
the conditions set forth herein and in Annex A attached hereto, which is hereby
incorporated by reference and shall be binding upon the parties as if fully set
forth herein, and, to the extent reasonably within its control, to cause the
conditions to such reset and resale herein (including Annex A) to be met.  In
connection with such transaction, Initial Note Purchaser shall propose a
Remarketing Date, and Lessees shall use commercially reasonable efforts to
provide the Preliminary Offering Memorandum to Initial Note Purchaser on such
date. After the Remarketing Date, Initial Note Purchaser and Lessees, acting on
behalf of Owner Trustee, shall designate a mutually acceptable Repricing Date
and Reset Rate, which rate, in their respective best judgments, will be
sufficient to allow Initial Note Purchaser to resell the Notes at 100% of the
principal amount thereof in a transaction in accordance with Rule 144A.

          On or prior to the Repricing Date, Initial Note Purchaser and Lessees,
acting on behalf of Owner Trustee, shall determine the Reset Date, which date
may be postponed by mutual agreement of Lessees and Initial Note Purchaser.
Initial Note Purchaser and Lessees shall notify Owner Trustee and Owner
Participant of such Reset Rate and Reset Date and any postponements thereof.  On

and deliver a supplement to the Lease reflecting the adjustments described in
the preceding paragraph, and Owner Trustee and Indenture Trustee shall execute
and deliver a supplement to the Indenture reflecting such adjustments and

          If Initial Note Purchaser and Lessees, acting on behalf of Owner
Trustee, fail to set a Repricing Date within 10 Business Days after an initial
Remarketing Date, then Initial Note Purchaser and Lessees, acting on behalf of
Owner Trustee, may set one or more other Remarketing Dates in the manner
described in the first paragraph of this Section 10.01 until the earlier to

to the 120th day following the Delivery Date, on any date thereafter Initial
Note Purchaser may in its sole discretion resell some or all of the Notes in one
or more Unilateral Resales that are exempt from the registration requirements of
the Securities Act; provided that only the first such Unilateral Resale shall

result in a reset of the interest rate on the Notes.  In connection with the
first such Unilateral Resale, each of the parties to this Participation
Agreement agrees to effectuate the reset of the interest rate upon such
Unilateral Resale on the terms and subject to the conditions set forth in this
Participation Agreement (including Annex A hereto) and, if such resale shall be,
at the request of Initial Note Purchaser, in accordance with Rule 144A, each of
the parties agree, to the extent reasonably within its control, to cause the
conditions to such reset and resale herein (including Annex A) to be met.
Initial Note Purchaser shall designate a Remarketing Date on five Business Days'

provide the Preliminary Offering Memorandum to the Initial Note Purchaser. After

set not more than two subsequent Remarketing Dates in the manner described in
the first paragraph of this Section 10.02 within 30 days after the initial

          (b)  In connection with a Unilateral Resale other than a resale made
in accordance with Rule 144A as described in subsection (a) of this Section

Purchase.
- -------- 

          (a)  In order to exercise its right to purchase the Beneficial
Interest pursuant to Section 11.01, the applicable Lessee shall notify Owner

Participant in writing within 15 days after the giving of notice by such Lessee
to Lessor pursuant to Section 19(b) of the Lease of such election.  In addition,
in the case of a purchase pursuant to Section 19(a)(ii)(B) or (iii) of the

Beneficial Interest. In such case, such Fair Market Sales Value shall be
determined pursuant to the Appraisal Procedure (provided that the timetable for
the Appraisal Procedure shall be appropriately accelerated to meet the deadlines
set forth in the next sentence; provided that notwithstanding such acceleration 
                                --------     
any appraiser shall have adequate time to make a considered determination). At
least 15 days prior to the applicable Rent Payment Date, such Lessee shall, if
it desires to exercise its right to purchase the Beneficial Interest Pursuant to
Section 11.01, give irrevocable notice to Owner Trustee, Owner Participant and 
- -------------                            
Indenture Trustee stating that such Lessee will purchase the Beneficial Interest
pursuant to Section 11.01.
            ------------- 

          (b)  On the date of purchase, upon receipt by Lessor of (i) the
Beneficial Interest Purchase Price minus (ii) the principal amount of the Notes
then outstanding (after payment of all Interim Rent and Base Rent remaining
unpaid that was due prior to the date of such purchase), and, in the event that
the date of purchase is a Rent Payment Date on which a Scheduled Rent payment
designated as an "arrears rent" on Schedule A is due, upon receipt by Lessor of
all such Scheduled Rent designated as "arrears rent" due on such Rent Payment
Date as set forth on Schedule A to the Lease, and the Rent Differential Amount,
if any, and all other Supplemental Rent due by Lessee on such Rent Payment Date
to or distributable to Owner Participant to and including such date of purchase
(without giving effect to any applicable grace periods), Owner Trustee shall
distribute to Owner Participant all such amounts received by it and all other
cash then held by it (other than cash distributable to Owner Trustee in its
individual capacity), and immediately thereafter Owner Participant shall
transfer the Beneficial Interest free and clear of all Owner Participant's Liens
to Lessees pursuant to an instrument of conveyance in form and substance
reasonably satisfactory to Lessee; provided that, subject to Section 14.15, 
                                   --------                  -------------
Owner Participant shall have been released from any obligations under the
Operative Documents arising after such purchase except to the extent that such
obligations are attributable to events or circumstances occurring prior to the
purchase of the Beneficial Interest by Lessee.

          (c)  Each of Owner Participant, Owner Trustee, and Indenture Trustee
at the cost and expense of Lessees and on an After Tax Basis, will cause to be
promptly and duly taken, executed, acknowledged and delivered all such further
acts, documents and assurances as Lessees reasonably may 

                                      65

request in order to carry out the intent and purpose of this Section 11 and the

transactions contemplated hereby.

          (d)  As a condition to such Lessee's right to purchase the Beneficial
Interest pursuant to Section 11.01 (unless such Lessee shall assume the
                     -------------                                     
obligations of Owner Trustee pursuant to the next sentence), on the date of
purchase such Lessee shall have provided to Indenture Trustee and Owner Trustee
an opinion of counsel for such Lessee, dated the date of purchase, which,
subject to usual or customary exceptions, shall be to the effect that, upon
consummation of such purchase, this Agreement, the Trust Agreement, the Lease
and, in the case of GMHE, the Guaranty Agreement constitutes the legal, valid
and binding obligation of such Lessee, enforceable against such Lessee in
accordance with its terms except as the same may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the rights of creditors generally and by general principles of equity, and
except as limited by applicable laws that may affect the remedies provided for
in the Lease, which laws, however, do not in the opinion of such counsel make
the remedies provided for in the Lease inadequate for the practical realization
of the rights and benefits provided for in the Lease.  In the event such Lessee
is unable to provide such opinion, concurrently with the purchase of the
Beneficial Interest Lessees shall assume (on a full recourse basis) the
obligations of Owner Trustee under the Notes and under the Indenture in
accordance with, subject to the conditions of and with the effect provided in
Section 5.05(a) hereof and Section 2.13 of the Indenture, and upon such
- ---------------                                                        
assumption such Lessee shall have the right to terminate the Trust Agreement.

          (e)  Owner Trustee and Lessees acknowledge and agree that the former
Owner Participant which shall have transferred the Beneficial Interest to a
Lessee pursuant to this Section 11.02 (the "Transferor") is entitled to all Rent
                        -------------                                           
which by its terms is payable in arrears accrued to and including, or
attributable to events or circumstances occurring prior to, the date of purchase
pursuant to this Section 11.02.  Owner Trustee hereby agrees that upon receipt
                 -------------                                                
by it of any amounts in respect of such Rent, it will forthwith pay over such
amounts to the Transferor.

          (f)  From and after any purchase of the Beneficial Interest pursuant
to this Section 11.02, (i) the Transferor shall be released from its liability
        -------------                                                         
hereunder and under the 

                                      66
<PAGE>
 
other Operative Documents to which it is or will be a party in respect of
obligations to be performed on or after the date of such purchase, and (ii) such
Lessee shall be deemed "Owner Participant" for all purposes of the Operative
Documents and each reference herein to Owner Participant shall thereafter be
deemed a reference to such Lessee for all purposes.

condition to such refunding, Lessees will be liable for, and shall pay, on an
After-Tax Basis, the reasonable out-of-pocket expenses incurred by Owner

     six months;

                          ------

          (i)  [Intentionally Omitted]

          (j)  no such transfer shall be to a Person nor shall such transfer be
     executed in a manner that would result in the loss, recapture, offset or
     other disallowance, elimination, reduction, or disqualification of all or
     any portion of the investment tax credit previously claimed by either
     Lessee, which investment tax credit is represented by STLC to fully vest no

     Lessees such information as is reasonably necessary for Lessees to
     determine Owner Participant's compliance with this clause (j), either
     Lessee shall have given Owner Participant at least seven days prior written
     notice of any such result.

          Section 13.03.  Effect of Transfer.  From and after any transfer
                          ------------------

transfer shall be released, to the extent of the obligations assumed by the
Transferee, from its liability hereunder and under the other Operative Documents
to which it is or will be a party in respect of obligations to be performed on
or after the date of such transfer.  Upon any transfer by Owner Participant in
accordance with this Article XIII, the Transferee shall be deemed "Owner

Documents and each reference herein to Owner Participant making such transfer
shall thereafter be deemed a reference to such Transferee for all purposes,
except as provided in the preceding sentence. To the extent permitted by law,
the failure to effect any such transfer in accordance with this Article XIII

sentence shall not constitute a waiver of any other claims any party hereto may
have as a result of such failure.

                          -----------                                           
extent reasonably so requested by Owner Participant and at the expense of Owner
Participant (except to the extent Lessee is obligated to pay such expenses under
other provisions of the Operative Documents), use good faith efforts to assist
Owner Participant in effecting any transfer of its interest in the Lessor's
Estate pursuant to this Article XIII.

more than one Owner Participant, that Lessees shall have consented to such
transfer prior to the effective date thereof, provided that no such consent
shall be required if all such Owner Participants shall have agreed in a manner
reasonably satisfactory to Lessees that if the provisions of the Operative
Documents require or contemplate the waiver, consent or direction of Owner
Participant, such provisions shall be deemed satisfied by the waiver, direction
or consent of Owner Participants holding a majority of the beneficial interests
in the Trust Estate, except in the case of any such waiver, direction or consent
affecting less than all of the Transponders, in which case only the action of
Owner Participant having the entire beneficial interest in such Transponders (or
Owner Participants holding a majority of the beneficial interests in such
Transponders, as the case may be) shall be required.

          Section 14.04.   Obligation to Purchase for Removal.
                           ---------------------------------- 

          (a) If, at any time following the expiration or earlier termination of
the Lease and prior to the end of the useful commercial life of the Satellite,
STLC elects to exercise its right with respect to a Removal of the Satellite
pursuant to clause (i) of the first sentence of Article 14 of the Purchase
Agreement (a "Voluntary Removal"), then within 5 days of receipt of the
appraisal required hereunder, Lessees shall purchase, and pay to Lessor in
immediately available funds the Removal Purchase Price of all, but not less than
all, Transponders then owned by Lessor or Owner Participant, regardless of
whether any such Transponder, at the time of the Voluntary Removal, failed to
comply with the Transponder Performance Specifications or otherwise was a
Failed Transponder.  STLC shall not be required to wait until the appraisal has
been completed and payment made to do the Removal; provided it shall pay
                                                   --------             
interest on the Removal Purchase Price at the Prime Rate from the date of
removal to, but excluding, the date of payment.  In all cases of a Removal other
than a Voluntary Removal, including a Removal pursuant to clause (ii) of the
first sentence of Article 14 of the Purchase Agreement or where Seller is
required to undertake such a Removal after the expiration of the Lease Term due
to actions by the FCC or other Governmental Authority not sought by Lessees
(collectively referred to as "Involuntary Removals"), Lessees shall have no
payment or other obligation to Lessors or Owner Participant as a result of such
removal.

          (b) The Removal Purchase Price for each such Transponder purchased
hereunder shall be the Fair Market Sales Value thereof, if any, as determined in
accordance with the Appraisal Procedure, which shall be commenced as soon as is
practicable after STLC determines to make the Voluntary Removal.  Any such
determination of Fair Market Sales Value of any removed Transponder shall be
made on the assumption that, but for such Voluntary Removal, such Transponder
would not have been taken out of service pursuant to the Purchase Agreement
except as, and until, an

                                      78
<PAGE>
 
Involuntary Removal occurred or the useful commercial life of the Satellite
would otherwise have ended had Seller not made the Voluntary Removal.  The
valuation date will be the Removal Date.  Upon compliance by STLC with all the
terms of this Section 14.04, Buyer shall transfer title to such Transponders to
              -------------                                                    
STLC without any representation, warranty or recourse whatsoever except as to
the absence of Lessor Liens and Owner Participant Liens.  After any such
purchase, neither STLC nor any Affiliate thereof shall use any Transponder for
any revenue-producing purpose.

required to disclose Proprietary Information pursuant to clause (F) of this
paragraph, Recipient shall promptly notify Lessees of such disclosure
requirement and upon the request of Lessees shall to the extent practicable at
the Lessees' sole cost and expense and with counsel reasonably satisfactory to
Recipient, fully cooperate with Lessees, in contesting such disclosure. If after
such contest disclosure is still required, then Recipient shall seek, if
practicable, confidential treatment of such information from the applicable

inform Recipient that such information is deemed proprietary and shall provide
Recipient with a brief written description of such information within thirty
(30) days of such disclosure, identifying therein the manner, place, and date of
such disclosure and the names of Recipient's representatives to whom such
disclosure was made whereupon the provisions of this agreement shall become
applicable to such Proprietary Information. Proprietary Information shall also

not be construed to be a waiver of any other right, power or remedy.  No delay
or omission by any party in the exercise of any right, power or remedy or in the
pursuant of any remedy shall impair any such right, power or remedy or be
construed to be a waiver of any default or to be an acquiescence therein.  No
express or implied waiver by any party of any default shall in any way be, or be
construed to be, a waiver of any future or subsequent default.

          Section 15.15.  Survival of Agreement.  The representations,

as Supplemental Rent any portion of the Lessor Payment Amount not remitted to
Indenture Trustee by Lessor. Lessor shall give notice to Lessee and Indenture

affect Lessee's obligations under this Section 3(c)(ii).

               (iii)  As Supplemental Rent, Lessee shall pay, when due, on
behalf of Lessor, (A) to Contractor (or the Substitute Service Provider, if

          (d)  Method of Payment.  Subject to Section 21, all Rent (other than
               -----------------
Excepted Payments) payable to Lessor shall be paid to Indenture Trustee for so
long as the Lien of the Indenture shall remain in effect and thereafter to Owner
Trustee. All other Supplemental Rent (including any Excepted Payment) payable to
any Person pursuant to any Operative Document or any Hughes Agreement shall be

Rent shall be made by Lessee in immediately available funds, on or before 12:00
noon (local time, at the place of payment as designated in Section 3(j) hereof),
on the scheduled date on which such payment shall be due, unless such scheduled
date shall not be a Business Day in which case such payment shall be due and
payable on the immediately succeeding Business Day with the same force and
effect as if made on such scheduled date, and (provided such payment is made on
such next succeeding Business Day) no interest shall accrue on the amount of
such payment from and after such scheduled date.

          (e)  Late Payment.  If any Rent shall not be paid when due, Lessee
               ------------
shall pay to Lessor or to Indenture Trustee, as the case may be (or, in the case
of Supplemental Rent, to any Person entitled thereto as provided herein or in
any other Operative Document or Hughes Agreement), as Supplemental Rent,
interest (to the extent permitted by law) on such overdue amount from and
including the due date thereof to but excluding the date of payment thereof
(unless payment is made after 12:00

               ---------------
Lease (including, without limitation, Sections 3(h) and 4) or any other
Operative Document or Hughes Agreement, (1) for any Transponder, the amount of
Interim Rent, Base Rent, Supplemental Rent and Advance Amount payable on any day

Section 4 (excluding, in each case, any portion thereof constituting an Excepted
Payment), shall be at least equal to the amount of scheduled principal and
accrued interest due and payable on the Notes outstanding on such day in respect

payable under this Lease on any such date in respect of such Transponder
(excluding, in each case, any portion thereof constituting an Excepted Payment),
shall be at least equal to the amount of principal and accrued interest and
Premium, if any, which would be due and payable on the Notes outstanding on such
date in respect of such Transponder, assuming such date or such applicable EBO
Date, as the case may be, was the date such payment was due on the Notes in
respect of such Transponder in connection with any payment by Lessee of such
Stipulated Loss Value, Termination Value or any EBO Amount.

          (g)  Net Lease; No Setoff; Etc.  This Lease is a net lease and,

(8) any claim that STLC or GMHE has or might have against any Person, including,
without limitation, Indenture Trustee, any Noteholder, Lessor or Owner
Participant (but this Section 3(g) shall not constitute a waiver of any such
claims); (9) any failure on the part of Lessor, Indenture Trustee, Owner
Participant or any Noteholder to perform or comply with any of the terms hereof
or of any other Operative Document or Hughes Agreement;

(10) any invalidity or unenforceability or impossibility of performance, or
disaffirmance, of any provision of this Lease or any of the other Operative
Documents or Hughes Agreement, whether against or by STLC or GMHE or otherwise;
(11) any Applicable Laws now or hereafter in force; (12) any failure to obtain
any required governmental consent for a transfer of rights or title on the
Delivery Date to the Lessor or any other Person; (13) any amendment or other
change (except as to the subject matter of any such amendment or change), or any
assignment of, any rights under any Operative Document or Hughes Agreement, or
any waiver or other action or inaction under or in respect of any Operative
Document or Hughes Agreement, or any exercise or nonexercise of any right or
remedy under or in respect of any Operative Document or Hughes Agreement,
including, without limitation, any foreclosure or other remedy under the
Indenture or this Lease or the sale, pursuant to any such foreclosure or such
exercise of other remedy, of any Transponder or any portion thereof or interest
therein; or (14) any other occurrence whatsoever, whether similar or dissimilar
to the foregoing, whether or not Lessee shall have notice or knowledge of any of
the foregoing.  Except as expressly provided herein, Lessee, to the extent
permitted by law, waives all rights now or hereafter conferred by statute or
otherwise to quit, terminate or surrender this Lease, or to any diminution or
reduction of Rent payable by Lessee hereunder.  If this Lease shall be
terminated in whole or in part for any reason whatsoever except as expressly
provided herein, Lessee shall nonetheless pay to Lessor (or, in the case of
Supplemental Rent, to Lessor for its own account or to any Person entitled to
such Supplemental Rent as specified herein or in the appropriate Operative
Document or the Hughes Agreement), an amount equal to each Rent payment at the
time and in the manner that
 
                                      9 
<PAGE>
 
such payment would have become due and payable under the terms of this Lease if
it had not been terminated in whole or in part. Except with respect to payment
of any Advance Amount pursuant to Section 3(b)(i)(A) and 3(c)(ii), each payment
of Rent shall be final, and the Lessee agrees not to seek to recover all or any
part of any such payment from the Lessor, the Indenture Trustee or the Owner
Participant for any reason under any circumstance whatsoever; provided, however,
                                                              --------  -------
that nothing contained in this Section 3(g) shall prevent the Lessee from
bringing an action for damages suffered by the Lessee as a result of the breach
by any Person of any obligation of such Person expressly stated in any Operative
Document or Hughes Agreement or for equitable relief to obtain compliance with
any such obligation, or for the return of mistakenly paid amounts of any Rent.
Nothing contained in this Section 3(g) shall be construed as: (1) a guaranty of
(i) the value of the Transponders upon termination of the Basic Term or any
Renewal Term or (ii) the useful life of the Transponders or (iii) payment of any
of the Notes; or (2) a prohibition of assertion of any claim against any
manufacturer, supplier, dealer, vendor, contractor, subcontractor or installer
with respect to the Transponders; or (3) a waiver by Lessee of its right to
assert and sue upon any claims it may have against any other Person in one or
more separate actions.


          (h)  Repayment Of Advance Amount.  Lessee shall be repaid, in the
               ---------------------------
manner provided in the next sentence, any Advance Amount (plus interest on the
outstanding portion thereof at a simple interest rate of 14% per annum from the
date that any portion of such mount is advanced by Lessee to but not including
the date it is repaid by Lessor) (the "Repayment Amount").  The Lessee shall be
                                       ----------------
entitled to offsets (without duplication) against any payments of Rent (other
than as limited by the three

provisos to this sentence) due from Lessee to Lessor or Owner Participant
(including, without limitation, Interim Rent, Base Rent, Stipulated Loss Value,
Termination Value or the applicable EBO Amount and all other amounts payable to
Lessor in connection with any termination of this Lease, but excluding Excepted
Payments payable to the Trust Company) until Lessee has received the Repayment
Amount, whether by cash payment, offsets as herein provided, or any combination
thereof; provided, however, that in case of any payment due to Lessor from
         --------  -------
Lessee, Lessee's right of offset shall be limited to the portion of such
payment, if any, distributable to Lessor or Owner Participant thereunder;
provided further, however, that no such offset or aggregate combined effect of
- -------- -------  -------
separate offsets shall reduce the amount of any installment of Interim Rent,
Base Rent, Supplemental Rent due under Section 3(b)(i)(A) or Section 3(c)(ii)
Stipulated Loss Value, Termination Value or the EBO Amounts as of any date
payable under this Lease to an amount that would be in contravention of the
minimum payment requirements of Section 3(f); and provided further, however,

Bankruptcy Default or Event of Default has occurred and is continuing.

Agreements, which shall be payable to such other Persons in accordance with
written instructions furnished to Lessee by such Persons) shall be paid by
Lessee to Lessor to its account (Account Number 29377-0) at Rodney Square North,
Wilmington, Delaware 19890, Attention: Corporate Trust Administration.  All Rent
shall be paid by Lessee by wire transfer of immediately available funds in
Dollars.

deemed to be payments remitted by Lessor to Indenture Trustee in respect of
Lessor Interim Amount and/or Lessor Payment Amount, without duplication,

Termination Value, and EBO Amounts.
- ----------------------------------

          (a)  Adjustments to Scheduled Rent.  Subject to the following
               -----------------------------                        
provisions of this Section 4 and to the provisions of Section 3(f), the amounts
of Scheduled Rent shall be appropriately adjusted by such amounts as shall
preserve Owner Participant's Net Economic Return with respect to the
Transponders, in the event that for any reason:

               (i)    The Delivery Date for the Transponders is a date other
     than as set forth therefor in Schedule III to the Participation Agreement;

               (ii)   The Lessor Interim Amount or the Lessor Payment Amount is
     other than the respective amounts set forth therefor in Schedule III to the
     Participation Agreement, or the actual amortization schedule attached as

                                      12
<PAGE>
 
     Schedule X to the Notes on the Delivery Date is other than the Assumed
     Amortization Schedule.

               (iii)  the Debt Commitments with respect to the Transponders is
     other than as set forth in Schedule III to the Participation Agreement;

               (iv)   (A) the amount of Transaction Costs with respect to the
     Transponders paid by Lessor as a percentage of Buyer's Cost of the
     Transponders is other than as set forth as "Estimated Transaction Costs" in
     Schedule III to the Participation Agreement, or (B) the date on which the
     Transaction Costs with respect to the Transponders are actually paid by
     Lessor is other than the Delivery Date for the Transponders or (C) Lessee
     pays any of Lessor's Transaction Costs pursuant to Section 9.01 (b) of the
     Participation Agreement;

               (v)    a Covered Tax Law Change with respect to the Transponders
     shall have occurred;

               (vi)   Lessee elects (with the consent of the Owner Participant,
     if required) to make an adjustment to Scheduled Rent in accordance with the
     Section of the Tax Indemnification Agreement referred to in Item 5 to
     Schedule E;

               (vii)  the Notes are refunded pursuant to Section 12.01 of the
     Participation Agreement (in which case the adjustment shall be made to take
     into account any change in the interest rate on, or the amortization
     schedule of, the applicable series of Refunding Notes from those of the
     Refunded Notes); or

               (viii) the interest rate on the Notes is reset as contemplated by
     Article X of the Participation Agreement.

                                       13
<PAGE>
 
          In connection with any adjustment to Scheduled Rent made pursuant to
this Section 4, appropriate corresponding adjustments shall be made to
Stipulated Loss Value, Termination Value, each EBO Amount, and the amortization
schedule for the Notes, as permitted by the Indenture, which amortization
schedule shall be satisfactory to Lessee and Lessor.  Any adjustment pursuant
hereto shall comply in all respects with the minimum payment requirements of
Section 3(f).  In addition, any adjustment pursuant hereto shall be made in the
same manner, and shall employ the same methodology, assumptions (including,
without limitation, each of the pricing assumptions set forth in Schedule III of
the Participation Agreement, as such pricing assumptions shall have been
modified by previous adjustments under this Section 4 or pursuant to the Tax
Indemnification Agreement), except as such assumptions shall have been modified
by the event giving rise to such adjustment, and constraints employed in the
original calculation of Scheduled Rent, Stipulated Loss Value, Termination Value
and the EBO Amounts as of the Delivery Date.  In making any adjustment pursuant
to clause (ii) or (viii) above, Interim Rent will be adjusted such that the
difference between (A) the sum of the Lessor Interim Amount and the Lessor
Payment Amount and (B) the Interim Rent does not exceed the amount set forth on
Schedule III to the Participation Agreement as the "Deferred Equity Limit."  If
Stipulated Loss Value (or any amount measured thereby), Termination Value or the
applicable EBO Amount shall become due and payable hereunder prior to completion
of an adjustment to Scheduled Rent pursuant to this Section 4, the adjustment
shall be completed prior to the date such payment is due. If required pursuant
to Section 6 of the Tax Indemnification Agreement, Stipulated

                                      14
<PAGE>
 
Loss Value, Termination Value and the EBO Amounts shall be appropriately
adjusted in accordance with the applicable provisions of this Section 4.

          It shall be a condition to the application of clause (v) of Section
4(a) that on or prior to the closing on the Delivery Date for the Transponders,
Owner Participant shall have provided Lessee with written notice of any Tax Law
Change or Proposed Tax Law Change with respect to the Transponders, or Lessee
shall have provided Owner Participant with written notice of any Tax Law Change
or Proposed Tax Law Change with respect to the Transponders, as to which Owner
Participant or Lessee, as the case may be, seeks or may seek the application of
this Section 4.

          (b)  Limitations on Adjustments.
               --------------------------

               (1) (A) Any adjustment of Scheduled Rent pursuant to this
Section 4 shall be computed in a manner so as to satisfy the minimum payment
requirements of Section 3(f) of this Lease. In addition, any adjustment of
Scheduled Rent (due with respect to the Basic Term) pursuant to this Section 4
shall be computed in a manner so as to satisfy the requirements of Sections
4.02(5), 4.07(1) and (2) and 4.08 of Revenue Procedure 75-28, 1975-1 C.B. 752,
as in effect on the Delivery Date; provided that the requirements of such
Section 4.08 shall be applied, in the case of any adjustment pursuant to this
Section 4, on a prospective basis taking into consideration only Scheduled Rent
(due with respect to the Basic Term) payable by Lessee from and including the
first Rent Payment Date as of which the adjustment takes effect; provided
                                                                 --------
further that any adjustment of Scheduled Rent (due with respect to the Basic
- -------                                                                    
Term) shall be governed by the foregoing requirements of Sections 4.07 and/or
4.08 of Revenue Procedure 75-28 only to the extent that Scheduled Rent (due with
respect to the Basic

                                       15
<PAGE>
 
Term) as of the Delivery Date for the Transponders satisfied such requirements
as in effect on the Delivery Date. (B) In the case of any adjustment pursuant to
clauses (i) through (iii) or (vi) of Section 4(a), any such adjustment of
Scheduled Rent (due with respect to the Basic Term) will be structured in such a
fashion so as not to create, solely during the periods from and after the Basic
Term Commencement Date, any risk that Section 467 of the Code will apply to
Owner Participant (determined without regard to any change in law that occurs
after the Delivery Date) greater than is created by the original rent structure
with respect to the Transponders in effect on the Delivery Date for the
Transponders. (C) In the case of any adjustment pursuant to clauses (iv), (v),
(vii) or (viii) of Section 4(a), any such adjustment of Scheduled Rent (due
with respect to the Base Term) shall satisfy (on a prospective basis), Section
467 of the Code and the Regulations, as in effect at the time of such
adjustment; provided, however, that in the event the Reset Date occurs after the
            --------  -------                                                
Basic Term Commencement Date, any such adjustment of Scheduled Rent (effected in
connection with the reset of the interest rate on the Notes) effective on such
Reset Date shall be made in a fashion to satisfy either the standard set forth
in clause (B) of this Section 4(b)(1) or the standard set forth in clause (C) of
this Section 4(b)(1) (selected by Lessor at such time) for satisfying the
constraints of section 467 of the code.

               (2) [Intentionally Omitted]

               (3) In making any adjustment pursuant to this Section 4, no
adjustment shall be made to reflect the application of Section 168(d)(3) of the
Code.

          (c) Timing of Adjustments. All adjustments to be made pursuant to
              ---------------------                                      
this Section 4 shall be made on and shall be effective as of the Delivery Date
for the

                                       16
<PAGE>
 
Transponders if practicable and to the extent not then practicable, any such
adjustment shall be made as soon as practicable after the event giving rise to
the adjustment and shall in each case be made in respect of installments of
Scheduled Rent becoming due on or after 15 days after the date such adjustment
is made; provided that all adjustments to be made pursuant to clause (i) through
(iii) of Section 4(a)(1) shall be made no later than September 1, 1992;
provided, further, that with respect to an adjustment pursuant to clause (viii)
- --------  -------  ----
of Section 4(a), such adjustment shall made be on or prior to the Repricing
Date.

          (d)  Confirmation of Adjustments.
               ---------------------------

               (1) The amount of any adjustment pursuant to this Section 4
shall be determined by Owner Participant, which shall provide to Lessee, Lessor
and Indenture Trustee notice of such adjustment accompanied by an Officer's
Certificate of Owner Participant, which Officer's Certificate shall set forth
the amount of and the reason for any such adjustment and which shall confirm
that such adjustment was made in accordance with the provisions of this Section
4. Such adjustment shall, subject to the following provisions of this Section
4(d), become effective as of the date therein set forth (determined in
accordance with Section 4(c)) upon delivery by Owner Participant to Lessee of
such notice and Officer's Certificate.

               (2) Within twenty (20) Business Days after receipt of an
Officer's Certificate pursuant to paragraph (d)(1) above, if Lessee believes
that such adjustment is incorrect, Lessee may request that such adjustment be
verified by one of the six largest U.S. independent public accounting firms,
including Owner Participant's regular independent accounting firm, as selected
by Owner Participant. In such verification

                                       17
<PAGE>
 
process, such accounting firm shall be given access by Owner Participant to the
assumptions, methods of calculation, computations, computer programs and files
employed by Owner Participant in calculating such proposed adjustment and
employed in the original calculation of Scheduled Rent, Stipulated Loss Value,
Termination Value and the EBO Amounts as of the Delivery Date, subject to the
execution of such confidentiality agreements as Owner Participant shall
reasonably request. Any revised adjustment resulting from such verification
shall become effective on the next Rent Payment Date occurring on or after 15
days after such verification has been concluded.

          (3) Such verification by such accounting firm shall be at the expense
of Lessee unless such verified adjustment results in a readjustment in favor of
Lessee that exceeds 5 basis points in the Net Present Value of Scheduled Rent,
in which case verification shall be at the expense of Owner Participant. Such
determination of adjustment by Owner Participant, or, if so requested in
accordance with Section 4(d)(2), such verified adjustment, as the case may be,
shall be conclusive and binding on the parties to the Participation Agreement.

     (e) Further Assurances. At the time any adjustment is made pursuant to
         ------------------                                              
this Section 4, the parties hereto shall enter into a supplement to this Lease
to reflect such adjustment and shall enter into such amendments to the other
Operative Documents (including an amendment to Schedule III to the Participation
Agreement) and do such further acts as may be reasonably required in order to
effectuate such adjustment; provided that such adjustment shall become effective
as provided in Section 4(d) without regard to the date on which such supplement
to this Lease is executed and delivered.

through its own actions or inactions, interfere with the quiet enjoyment of any
Transponder by Lessee and agrees that it will not directly or indirectly create,
incur, assume or suffer to exist any Lessor Lien on or with respect to any
Transponder. The provisions of this Section 5(a) have been negotiated, and
except as expressly provided in the Operative Documents, the foregoing

diminish or otherwise affect any right Lessee may have with respect to any
Transponder against any other third person. Neither Lessor, the Trust Company,
Owner Participant, any Noteholder or Indenture Trustee shall at any time be
required to inspect such Transponder, nor shall any inspection by Owner
Participant, Lessor, the Trust Company, any Noteholder or Indenture Trustee be
deemed to affect or modify the provisions of this Section 5(a).

          (b) Exercise of Certain Rights under the Hughes Agreements.

Agreement to cause Lessee or Seller to defend such title in accordance with the
provisions hereof or thereof. Lessor hereby authorizes Lessee, for so long as
this Lease shall be in effect with respect to any Transponder and so long as no
Event of Default shall have occurred and be continuing, to exercise in the name

material adverse effect on Lessor's interest in the Transponders upon expiration
or termination of the Lease) against such Seller, Hughes Services, other
manufacturer or supplier or other user all rights, powers and privileges of
Lessor, and to receive all benefits of Lessor with

Purchase Agreement or of Owner under the Service Agreement; provided that
                                                            -------- ----
notwithstanding any term or provision of this Section 5(b)(ii) to the contrary,
Lessor and Owner Participant shall retain the right to any Excepted Payment
owing to either of them, respectively.

         (iii) If, notwithstanding the foregoing, Lessor receives any payment
of any kind whatsoever under the Purchase Agreement or the Service Agreement
during the Lease Term to which Lessee is entitled pursuant to Section 5(b)(ii),
Lessor shall upon receipt remit to Lessee the full amount of the payment
received by it under the Purchase Agreement, or the Service Agreement, as the
case may be; provided that no Payment Default, Bankruptcy Default or Event of
Default shall have occurred and be continuing; provided further, however, that
                                               -------- -------  -------        
Lessor shall promptly remit such amounts to Lessee at such time as no Payment
Default, Bankruptcy Default or Event of Default is continuing.


   SECTION 6. Liens; Quiet Enjoyment; Assignment and Sublease.
              -----------------------------------------------
 
          (a) Liens. Lessee shall not directly or indirectly create, incur,

assume or suffer to exist any Lien on or with respect to any Transponder, the
Lessor's Estate or the

Indenture Estate, or title thereto or any interest therein, except Permitted
Liens. Lessee's obligations under this Section 6(a) with respect to any Lien,
other than Owner Participant Liens or Lessor's Liens, on any Transponder arising
prior to the termination of this Lease shall survive such termination.

          (b) Quiet Enjoyment. So long as no Event of Default shall have
              ---------------                                         
occurred and be continuing, as between Lessee and Lessor, Lessee shall have the
exclusive rights to possession and control of each Transponder and Lessor shall
not take any action that interferes with the quiet enjoyment of the use or non-
use of any Transponder by Lessee, and Lessee shall have the right to use or not
use such Transponder in its sole discretion.

          (c) Assignment, Sublease by Lessee. So long as no Event of Default
              ------------------------------                              
shall have occurred and be continuing, Lessee may, without the consent of or
prior notice to Lessor, assign its leasehold interest in whole or in part
(including any of Lessee's rights or options hereunder) in this Lease or
sublease, license, enter into short term or long term service contracts,
transfer Control of, or permit Seller or any other Person (including, without
limitation, to a "tax-exempt" entity as defined in Section 168(h) of the Code)
to use all or any part of any Transponder or Transponders during the Lease Term
(collectively the "Use Agreements") (such Use Agreements not including for the
purposes of Sections 6(c)(i), 6(c)(iv) and 6(c)(v) any occasional use service
contract for the provision of part-time, occasional use transponder capacity on
available Ku-band or C-band transponders on satellites, including the Satellite,
owned or operated by STLC or any Affiliate and not expressly required to be made
available on

the Satellite, an "Occasional Use Service Contract")), on and subject to the
following terms and conditions:

               (i) such Use Agreements shall expressly provide that the
     rights of any sublessee, assignee, user or operator thereunder
     (collectively, "User") are subject and subordinate to all the terms and
     conditions of this Lease, including, without limitation, Lessor's right to
     repossess any Transponder and terminate such Use Agreements upon the
     occurrence of an Event of Default;

               (ii) Lessee shall remain primarily liable to Lessor for the
     performance of all of the terms of this Lease to the same extent as if such
     Use Agreements had not occurred;

               (iii) such Use Agreements shall not be in violation of Applicable
     Law and the terms and conditions thereof shall not be inconsistent with the
     terms of this Lease, provided that the term thereof (as well as the term of
     any Existing Lease set forth in Exhibit D-1 or D-2, hereto) may extend
     beyond the expiration of the Lease Term, subject to the provisions of
     Section 6(e);

               (iv) such Use Agreements shall prohibit the User from entering
     into any Further Use Agreements without obtaining (x) the written consent
     of Lessee and (y) an agreement by any such User further transferring its
     rights to comply with the terms and conditions of this Section 6(c),
     including, without limitation, the requirement that any such Further Use
     Agreement be expressly subject and subordinate to this Lease; and

               (v) if Lessee is required to obtain or maintain casualty
     insurance pursuant to Section 9(b)(i), then within thirty (30) days
     following the date Lessee
                                       25
<PAGE>
 
      shall have Actual Knowledge of the existence of the conditions under
      Section 9(b)(i) that require Lessee to obtain or maintain such insurance,
      Lessee shall execute and deliver to Lessor an assignment agreement (in
      form and substance reasonably acceptable to Lessor) assigning to Lessor as
      additional security for all of Lessee's obligations hereunder its rights,
      with respect to the provision of transponder capacity on the Satellite
      only, under all Use Agreements, except that Lessee shall not be required
      to obtain a User's acknowledgement of or consent to such assignment nor to
      notify (and in connection therewith, Lessor hereby agrees not to notify)
      any User of such assignment unless an Event of Default shall have occurred
      and be continuing. Such assignment agreement shall provide that Lessee
      shall remain primarily liable to User to perform its obligations under
      such Use Agreement. 

Subject to the provisions of this Section 6(c), Lessee may render any
communications service, so long as the foregoing provisions of this Section 6(c)
shall apply, and Lessee or any Affiliate may provide Transponder or Transponders
capacity by Lessee or any Affiliate of Lessee to any of their respective
customers in the ordinary course of their respective businesses; provided that
no rendering of any such communications service or the providing of Transponder
or Transponders capacity, and neither the entering into or performing of any
agreement related thereto, shall operate to reduce, excuse or in any way affect
the obligations of Lessee hereunder and under the other Operative Documents to
which it is a party and as to which Lessee will remain primarily liable.

          (d) Existing Leases. As of the date hereof, Lessee is a party to
              ---------------
existing leases on certain Transponders, and the lessees under certain of such
leases are, in turn,

                                       26
<PAGE>
 
sublessors under subleases, which leases and subleases (not including any
Occasional Use Service Contract) are listed in Exhibit D-1 (as to the leases)
and Exhibit D-2 (as to the subleases) (collectively, the "Existing Leases").
                                                          ---------------
Contemporaneously with the execution and delivery of this Lease, Lessee is
assigning to Lessor, pursuant to the Assignment Agreement dated as of December
27, 1991 between STLC and Owner Trustee, as additional security for all of
Lessee's obligations hereunder its rights under such Existing Leases, with
respect to the provision of transponder capacity on any Transponder and on the
Satellite only (other than the Chevron, ISBN Space Segment Services Agreement
No. CITCO839, dated May 15, 1990); provided, however, that Lessee shall not be
                                   --------  -------
required to obtain an acknowledgement of or consent to such assignment from any
Sublessee under any Existing Leases or to notify, and in connection therewith
Lessor hereby agrees not to notify, any such Sublessees of the assignment unless
an Event of Default shall have occurred and be continuing; and provided,
                                                               --------
further, however, that Lessee shall remain primarily liable to such Sublessees
- -------  -------
to perform Lessee's obligations under the Existing Leases. In addition, Lessee
shall remain primarily liable to Lessor for the performance of all of the terms
of the Lease to the same extent as if such Existing Lease had not occurred.

     (e) Return of Transponders. (i) Any Use Agreement may by its terms extend,
         ----------------------
or be extended by the User, beyond the Lease Term and (ii) any Existing Lease
may be extended by the Sublessee beyond the Lease Term (a Transponder with
respect to which such Use Agreement or Existing Lease provides for such
extension, a "Selected Transponder"); provided that, each Transponder
                                      -------- ----
(including, but not limited to, any Selected Transponder) shall, at the time of
Redelivery to Lessor pursuant to Section 10,

                                      27
<PAGE>
 
  be free and clear of any continuing obligation to any User, Sublessee or other
  Person, unless Owner Participant shall otherwise expressly agree in writing at
  the request of Lessee.

       SECTION 7. Operation; Maintenance; Compliance with Law; Location of
                  --------------------------------------------------------
  Satellite; Substitution of Transponders.
  ---------------------------------------

             During the Lease Term with respect to any Transponder:

             (a) Operation. Lessee shall observe and perform each and every
                 ---------                                               
obligation (and shall exercise all rights where failure to do so would have a
material adverse effect on Lessor's interest in the Transponders upon the
expiration or termination of the Lease) of Buyer under the Purchase Agreement
and Owner under the Service Agreement to the extent the same relate to such
Transponder, and shall keep the same in full force and effect. Lessee shall not
use any Transponder during the Lease Term or authorize any third party to use
such Transponder in breach of the Purchase Agreement, the Service Agreement or
any Applicable Laws applicable to Lessee, Lessor (in its capacity as such
Transponder owner without regard to Applicable Laws applicable to Lessor solely
because of it being engaged in a regulated activity of any type other than the
owning and leasing of the Transponder), Owner Participant (in its capacity as
such Transponder owner without regard to Applicable Laws applicable to Owner
Participant solely because of it being engaged in a regulated activity of any
type other than the owning and leasing of the Transponder), such third party or
such Transponder (in each case, other than Applicable Laws as to which
noncompliance would not have an Adverse Effect), or in violation of any
authorization relating to such Transponder or the Satellite or Lessee issued by
any Governmental Authority having jurisdiction over such

                                       28
<PAGE>
 
 Transponder, the Satellite or Lessee (other than (i) any provision thereof as
 to which noncompliance would not have an Adverse Effect or (ii) unless the
 validity of such Applicable Law or authorization is being contested in good
 faith and by appropriate proceedings (but only so long as such proceedings do
 not involve any risk of civil or criminal liability to Lessor or Owner
 Participant, and do not involve any material danger of the sale, forfeiture,
 loss or diminution in value of such Transponder or the rights of Lessor or
 Owner Participant under any Hughes Agreement or any Operative Document and
 adequate reserves with respect thereto shall have been established in
 accordance with GAAP). As used herein, "Adverse Effect" shall mean that which
 would materially adversely affect the business, operations or properties of
 GMHE on a consolidated basis or involve any material danger (x) of the loss of
 any FCC authorization to operate the Satellite or maintain it in its assigned
 orbital location, (y) of any material adverse effect on the ability of STLC to
 perform its obligations hereunder and under the Purchase Agreement or of the
 sale, forfeiture, loss or diminution in value of any Transponder, or (z) of the
 imposition of criminal or civil liability on the Lessor or the Owner
 Participant.

      (b) Maintenance. Lessee hereby agrees to require Hughes Services to
          -----------
 fulfill all of its obligations under the Service Agreement. STLC shall fulfill
 all of its obligations under the Purchase Agreement. In connection therewith,
 Lessee will make all payments required to be made during the Lease Term to
 Hughes Services under the Service Agreement as Supplemental Rent pursuant to
 Section 3(c)(iii), and will on behalf of Lessor perform all other obligations
 thereunder required to be performed by Lessor, with respect to such Transponder
 during the Lease Term. So long as during the Lease Term, the Service Agreement
 or a Substitute Service Agreement shall have remained in
 
                                      29
<PAGE>
 
full force and effect and Hughes Services (or a Substitute Service Provider (as
defined below), if applicable) shall have performed all of its obligations
thereunder with respect to such Transponder, all maintenance, management and
monitoring responsibilities of Lessee in connection with such Transponder shall
be deemed fulfilled, and Lessee shall have no additional independent obligations
hereunder relating thereto.


     In the event that at any time during the Lease Term, the Service Agreement
shall no longer be in full force and effect or Hughes Services shall fail to
perform its obligations thereunder with respect to such Transponder, Lessee, at
its expense, shall maintain, manage and monitor, or cause to be maintained,
managed and monitored, the Satellite and such Transponder in good working order
and repair, ordinary wear and tear excepted, (i) in accordance with the higher
of (A) customary industry standards employed by owners of Ku-band transponders
on domestic communications satellites or (B) standards at least equal to those
used by Hughes Services or any of its Affiliates prior to such failure of
performance for other transponders on the Satellite or on another similar
satellite owned, leased or operated by Hughes Services or any of its Affiliates
(if at the time Lessee or any Affiliate maintains, manages or monitors
satellites similar to the Satellite for similar commercial purposes); (ii) in
compliance with all Applicable Laws (other than Applicable Laws as to which
noncompliance would not have an Adverse Effect); and (iii) in accordance with
all applicable requirements of any insurance policy then in effect as required
by Section 9 hereof. The foregoing notwithstanding, if, with respect to any
Transponder, Contractor or Substitute Service Provider is unable temporarily to
perform its maintenance obligations under the Service Agreement or any
Substitute Service Agreement due to any

                                      3O
<PAGE>
 
Force Majeure Event, then, provided such temporary failure to perform does not
cause a permanent material diminution in the value of such Transponder and is
capable of cure before any such permanent diminution in value would result, such
failure shall not constitute a breach of Lessee's obligations under this Lease.

     Without limiting the generality of the foregoing, at any time during the
Lease Term, if the Service Agreement shall not be in effect, Lessee will arrange
for Lessor to enter into and Lessee will keep in full force and effect for the
remainder of the Lease Term an agreement for the provision of services (the
"Substitute Service Agreement") comparable to those to be provided by Hughes
 ----------------------------
Services under the Service Agreement at a reasonable cost with a sound and
reputable service provider, which may or may not be an Affiliate of Hughes
Services (the "Substitute Service Provider"), and which such provider shall be
               ---------------------------
reasonably acceptable to Owner Participant. If Lessor enters into a Substitute
Service Agreement, it will assign its rights under such agreement to Lessee
during the Lease Term on the terms and conditions contained in Section 5(b)(ii).

     (c) Compliance with Law. During the Lease Term with respect to any
         -------------------
Transponder, Lessee or Contractor shall have and maintain all permits, licenses
and approvals required by the FCC or under any Applicable Law to operate the
Satellite and such Transponder and shall satisfy the requirements of the FCC and
any statute, regulation or order applicable to operators, users or lessees of
such Transponder; provided, however, that Lessee shall not be deemed to have
                  --------  -------
breached the foregoing covenant unless such non-maintenance or non-satisfaction
would have an Adverse Effect. To the extent permitted by law, Lessee or any
Affiliate shall prepare and file in timely

                                      31
<PAGE>
 
fashion, or, where Lessor, Owner Participant or Indenture Trustee shall be
required so to file, prepare and deliver to such Person within a reasonable time
prior to the date for filing, any reports with respect to any Transponder which
are required to be filed with any Governmental Body during the Lease Term for
such Transponder. Lessor shall notify Lessee promptly after Lessor has Actual
Knowledge of any reports or filings required of Lessor by law in connection with
its ownership of the Transponders; provided, however, that Lessor shall not
                                   --------  -------
incur any liability to Lessee for failure so to notify Lessee. If Lessee shall
fail to timely prepare, deliver or file any such report solely as a result of
the failure of Lessor, Owner Participant or Indenture Trustee timely to provide
Lessee with (i) any information required in such report which is in the
possession of Lessor, Owner Participant or Indenture Trustee and is not
reasonably available to Lessee or (ii) notice of the requirement of such report
if such report is required as to Lessor, Owner Participant or Indenture Trustee
for any reason other than such Person's interest in the Transponder or
Transponders then subject to this Lease, Lessee shall incur no liability to any
such Person failing to provide such information or notice, to the extent such
liability is incurred by the failure to provide such information. Lessor hereby
appoints Lessee its attorney-in-fact, to the extent permissible by Applicable
Law, to execute such reports in the name of Lessor and to file such reports, and
Lessor shall cooperate in furnishing Lessee such information as is available to
it which must be included in such, reports. Upon demand, Lessee shall reimburse
Lessor, Owner Participant or Indenture Trustee on an After-Tax Basis for any
reasonable out-of-pocket costs incurred by each such Person, respectively, in
connection with the preparation and filing of any such reports. Lessee shall, on
a periodic basis, furnish

                                      32
<PAGE>
 
Lessor, Owner Participant or Indenture Trustee a copy of all reports filed by
Lessee on behalf of any such Person pursuant to this Section 7(c).

          (d) Location of Satellite.
              ---------------------

          (i) Except as set forth in Section 7(d)(ii), Lessee may, upon receipt
of all necessary government approvals and permissions, and in accordance with
all Applicable Laws, at any time or times during the Lease Term, move the
Satellite to a different assigned orbital location; provided, however, that any
                                                    --------  -------
such move may be made only (1) at any time or times if required to comply with a
requirement of the FCC and not voluntarily sought by Lessee or any of its
Affiliates (an "FCC Ordered Move"); provided that Lessee shall contest in a
                ----------------    --------
commercially reasonable manner any proposed FCC Order requiring a new permanent
assignment of the Satellite to an orbital location outside the Authorized Range
and any temporary assignment of the Satellite to a location outside the
Authorized Range if Lessee has reason to expect, after consideration of the
available information, that moving the Satellite to such temporary location and
returning it to a location in the Authorized Range would result in the Satellite
failing to meet the Minimum Fuel Requirement at the time of Redelivery pursuant
to Section 10; (2) at any time or times during the Lease Term at the sole
discretion of Lessee (a "Discretionary Move"); provided, however, that a move to
                         ------------------    --------  -------
72 degrees West Longitude shall constitute a Discretionary Move; provided
further that no more than two Discretionary Moves may be made by Lessee; and
provided further that if Lessee shall renew the Lease and any such renewal term
- -------- -------
shall be for the remainder of the Transponders' useful commercial life, then
Lessee shall be entitled to make during such Renewal Term one additional
Discretionary Move; (3) at any time during the Lease Term, if the move (an
"Emergency
 ---------

                                      33
<PAGE>
 
Move") is to be made to the then FCC authorized orbital location of either (x)
- ----
the satellite commonly known as Galaxy IV (presently authorized at 99 degrees
West Longitude) or (y) Galaxy VII (presently authorized at 91 degrees West
Longitude) (or, in either case, for any replacement satellite therefor) in order
to fulfill Lessee's then-existing contractual commitments to transponder
purchasers, lessees or other users of transponder capacity on such satellites
which relate to late delivery, delivery failure or catastrophic failure; (4) if
necessary for Lessee to comply with its obligation to redeliver the Transponders
in an orbital location within the Authorized Range as provided in Section 10; or
(5) at any time after Lessee shall have exercised its option to acquire the
Transponders under Section 20(c), in which later case the provisions of this
Section 20(c), where applicable, shall apply.


     (ii) Lessee's right to move the Satellite as provided in Section 7(d)(i) is
subject to the satisfaction of the following conditions:

     (A) prior to Lessee's receipt of a license or other authorization from the
FCC to locate the Satellite in an orbital location within the Authorized Range
for its remaining useful commercial life (the "Permanent Location"), Lessee
cannot use a Discretionary Move to move the Satellite to an orbital location
outside of the Authorized Range (an "Alternative Location") unless Lessee shall
                                     --------------------
then have authorization to return the Satellite to an orbital location within
the Authorized Range or at 72 degrees West Longitude and Lessee has reason to
expect, after consideration of the available information, that such move to an
Alternative Location and return to either 72 degrees West Longitude or an
orbital position in the Authorized Range to which Lessee reasonably believes the
Satellite shall be
 
                                      34
<PAGE>
 
authorized to return would not result in the Satellite failing to satisfy the
Minimum Fuel Requirement applicable at the time of Redelivery pursuant to
Section 10;

     (B) after receipt by Lessee of a license or other authorization from the
FCC to locate the Satellite in the Permanent Location, Lessee may make a
Discretionary Move of the Satellite to an Alternative Location only if (x) the
Satellite shall be moved to such Alternative Location on a temporary basis, and
Lessee shall then have the authorization to return the Satellite to the
Permanent Location on or prior to the end of the Lease Term, and (y) Lessee has
reason to expect after consideration of available information that such move to
an Alternative Location and return to the Permanent Location would not result in
the Satellite failing to satisfy the Minimum Fuel Requirements applicable at the
time of Redelivery pursuant to Section 10;

     (C) any move of the Satellite pursuant to this Section 7(d) will be made in
accordance with such industry standards as are practiced when moving satellites
to a different orbital location and taking into account the circumstances
surrounding any such move (including, the necessity to move the Satellite on a
rapid basis when making an Emergency Move); and

     (D) in no case, except for an FCC Ordered Move, will Lessee move the
Satellite to an orbital location outside of the orbital arc between and
including 72 degrees and 105 degrees West Longitude.


    (e) Substitution of Transponders. Lessee shall have the right subject to the
        ----------------------------
conditions set forth in the following paragraph to substitute a transponder (a

                                      35
<PAGE>
 
"Replacement Transponder") aboard the Satellite for any Transponder which has 
 -----------------------
suffered an Event of Loss. Upon fulfillment of the conditions specified in this
Section 7(e), such Replacement Transponder shall be conveyed by Lessee to Lessor
and leased to Lessee hereunder.

     The substitution of a transponder pursuant to this Section 7(e) shall be
subject to fulfillment of the following conditions precedent prior to or on the
date of the proposed substitution to the reasonable satisfaction of Lessor and
at Lessee's sole cost and expense: (i) if the Lease is in effect with respect to
such Transponder, no Bankruptcy Default or Event of Default shall have occurred
and be continuing or will exist immediately following the proposed substitution;
(ii) on the date of such substitution, the Replacement Transponder (A) shall
meet the Transponder Performance Specifications set forth in Appendix C to the
Purchase Agreement, (B) shall have a total useful commercial life of 15 years or
more as measured from the Delivery Date, and (C) can reasonably be expected to
continue to meet such performance specifications for such period of 15 years or
more as measured from the Delivery Date (all of (A), (B) and (C) as determined
pursuant to the Appraisal Procedure); (iii) Lessor shall have received a bill of
sale substantially in the form of the Bill of Sale conveying title to such
Replacement Tramponder to Lessor; (iv) if so requested by Lessor, or for so long
as the Indenture shall be in effect by Indenture Trustee, Lessee shall have
entered into a Lease Supplement covering such Replacement Transponder and, if so
requested by Indenture Trustee, the Lessor shall have delivered an Indenture
Supplement to Indenture Trustee; (v) Lessor shall have good and marketable title
to such Replacement Tramponder free and clear of all Liens other than Permitted
Liens of the type discussed in clauses (a) and

                                      36
<PAGE>
 
(b) of the definition thereof; (vi) such Replacement Transponder shall be
covered by an assignment and consent instrument similar in form and substance to
the Consent and Agreement; (vii) Lessee shall have made arrangements reasonably
satisfactory to Lessor for Lessor to enter into the Service Agreement or the
Substitute Service Agreement or, if not then in effect, a service agreement
reasonably acceptable in form and substance to Lessor with respect to the
Replacement Transponder; (viii) no such substitution shall occur at any time
after the tenth anniversary of the Delivery Date; and (ix) Owner Participant
shall have received (a) an opinion of its tax counsel that Owner Participant
will not suffer any adverse tax consequences as a result of such substitution
(other than any such adverse tax consequences as would result from such
substitution under the Code or Regulations as in effect as of the Delivery Date)
and (b) an indemnity from Lessee satisfactory in form and substance to Owner
Participant for any such adverse tax consequences relating to such substitution
as Owner Participant may reasonably request. Upon the fulfillment of the
foregoing conditions, Lessor will Transfer to Lessee all of Lessor's right,
title and interest in and to the Transponder to be replaced as is, where is,
free and clear of all Lessor Liens and Owner Participant Liens, but otherwise
without warranty, and will deliver to Lessee such instrument as Lessee shall
reasonably request releasing such Transponder from this Lease. Upon such
substitution for all purposes hereof, such Replacement Transponder shall be
deemed to be a "Transponder" hereunder.

          (i)    Provided that no Payment Default, Bankruptcy Default or Event
of Default shall have occurred and be continuing, in the event that Lessee shall
in good faith determine that the Transponders, in the aggregate, have become
uneconomic, obsolete or surplus to Lessee's requirements (as evidenced by a
resolution to such effect adopted by the Board of Directors of HCI (the parent
of STLC)), Lessee shall have the option, during the Basic Term (and not during
any Renewal Term), upon furnishing a notice to Lessor and Indenture Trustee at
least 180 days prior to the effectiveness thereof to terminate this Lease with
respect to all, but not less than all, of the Transponders on any Rent Payment
Date on or after the date shown as Item 6 on Schedule E hereto (the "Termination
                                                                     -----------
Date"). As a condition to any transfer by Lessor of the Transponders or
- ----
retention by Lessor of the Transponders (each pursuant to this Section 8), any
necessary regulatory approvals in connection therewith shall have been obtained
(Lessee hereby agreeing to use reasonable best efforts to obtain or to assist
Lessor in obtaining such approvals).

          During the period from the giving of such notice of termination for
the Transponders until 60 days prior to the Termination Date, Lessee, as non-
exclusive agent for Lessor, shall use commercially reasonable efforts to solicit
unconditional cash bids from Persons other than Lessee or its Affiliates (it
being understood for the purposes of this Section 8 that "Affiliates" shall
include any other Person directly or indirectly controlling, directly or
indirectly controlled by,
                                       38

or under direct or indirect common control with, Lessee) to purchase such
Transponders on the Termination Date, and Lessee shall, during the period from
the giving of such notice of termination until 60 days prior to the Termination
Date (as set forth in the preceding paragraph), from time to time at the request
of Lessor or Indenture Trustee, inform Lessor and Indenture Trustee of the
results of its efforts and shall certify to Lessor and Indenture Trustee, at
least 60 days prior to the Termination Date, the amount and terms of each such
bid which has theretofore been submitted and the name and address of the party
submitting such bid. Lessor and Owner Participant shall each have the right to
solicit bids (or each to make its own bid, provided that any bid by Lessor or
Owner Participant shall be submitted to Lessee prior to the disclosure by Lessee
to Lessor or Owner Participant of any other bids), but shall be under no duty to
solicit bids or to inquire into the efforts of Lessee to obtain bids. Each such
bid (a) shall be for payment in full in cash and (b) shall not involve any
consideration to be received by Lessee or its Affiliates or be connected,
directly or indirectly, with any transaction between the purchaser and the
Lessee or its Affiliates, (collectively, a "Bona Fide Bid"). On or prior to the 
                                            -------------    
40th day prior to the Termination Date, Lessee may (provided that Lessee has not
previously cancelled a proposed termination except for a deemed cancellation as
provided in Sections 8(a)(ii) and 8(c) hereto), by notice to Lessor and
Indenture Trustee, cancel the proposed termination of this Lease for the
Transponders, whereupon this Lease shall continue in full force and effect with
respect to the Transponders.
 
                                      39
<PAGE>
 
     If Lessee does not cancel such proposed termination as set forth in the
last sentence of the preceding paragraph and any Bona Fide Bids are received on
or prior to the 60th day before the Termination Date, Lessee's notice of
termination shall become irrevocable on the 10th Business Day prior to the
Termination Date and Lessor shall on the Termination Date, provided that the
conditions of subsection (b) have been fulfilled, sell such Transponders to the
bidder which shall have submitted the highest Bona Fide Bid for such
Transponders and which has not defaulted on its bid (or to the next successively
highest bidders, if any, which shall have submitted Bona Fide Bids, in the case
of a default by the prior bidder, provided such sale shall have been consented
to by Lessee if the Bona Fide Bid related thereto is for an amount less than the
applicable Termination Value for the Transponders) for such Transponders upon
receipt in immediately available funds of the amount specified in such bid. Such
funds shall be paid either to Indenture Trustee or to Lessor, as required
pursuant to the Indenture. All reasonable out-of-pocket costs and expenses
incurred by Lessor or Indenture Trustee including, without limitation,
attorneys' fees, in connection with any notice of termination, regardless of
whether a sale is completed Or Lessee withdraws its notice of termination, shall
be paid by Lessee on an After-Tax Basis. 

     (ii) If no sale of the Transponders shall have occurred in accordance with
Section 8(a)(i) on the Termination Date, or if all bidders having submitted Bona
Fide Bids for such Transponders that were for an amount at least equal to
Termination Value for the Transponders (or if for less than such

                                      4O
<PAGE>
 
Termination Value, the sale to such bidder was consented to by Lessee) have
defaulted on such bids, then the Lease shall continue in full force and effect
and the termination notice given by Lessee shall be deemed to have been
cancelled by Lessee. If no sale of the Transponders shall have occurred in
accordance with Section 8(a)(i), as a result of a default by Lessor in its
obligation to sell the Transponders in accordance with Section 8(b), then Lessor
shall have been deemed to have exercised its election to retain ownership of the
Transponders pursuant to Section 8(c) hereof.

     (iii) Notwithstanding anything to the contrary in this Section 8(a), if the
bidder to whom the sale would otherwise have taken place shall have defaulted on
its bid within the 10 Business Day period prior to the Termination Date, Lessee
shall nonetheless make, on the Termination Date, all the payments specified in
Section 8(b) (other than the payment pursuant to the second sentence of Section
8(b)) and payment of Termination Value for the Transponders as of the
Termination Date. Promptly thereafter, Lessor shall use its reasonable
commercial efforts to sell the Transponders to an unaffiliated third party.
Lessor shall retain the net proceeds of any such sale in excess of Termination
Value for such Transponders as of the Termination Date. The net proceeds of such
sale up to but not exceeding Termination Value for such Transponders as of the
Termination Date shall be paid by Lessor to Lessee within 5 Business Days of
receipt of the proceeds of such sale. Upon payment by Lessee of all the amounts
due pursuant to this Section 8(a)(iii), the obligation of Lessee to pay Base
Rent with respect to the Transponders and Supplemental Rent, other than to pay
 
                                      41
<PAGE>
 
   Supplemental Rent attributable to acts, events or conditions occurring or
   existing on or prior to such termination with respect to such Transponders,
   shall terminate, such Transponders shall no longer be subject to this Lease
   and the Lease Term with respect to such Transponders shall end.

     (b) Termination Paments. As a condition to the obligation of Lessor to
         -------------------
terminate the Lease and to sell the Transponders pursuant to Section 8(a) on the
Termination Date therefor, Lessee shall on the Termination Date pay to Lessor
the sum of (A) all amounts of Base Rent for such Transponders due and unpaid
prior to such Termination Date and (B) in the event that the Termination Date is
a Rent Payment Date on which a Scheduled Rent payment designated as an "arrears
rent" on Schedule A hereto as adjusted pursuant to Section 4 is due, the sum of
any Scheduled Rent with respect to such Transponders designated as an "arrears
rent" on Schedule A hereto as adjusted pursuant to Section 4 and due on such
Termination Date, and the Rent Differential Amount with respect to such date, if
any, and (C) any other Rent then due with respect to such Transponders,
including Premium, if any, on the outstanding Notes. In addition, Lessor shall
retain the net proceeds of the sale of such Transponders and Lessee shall pay to
Lessor the excess, if any, of Termination Value for the Transponders (computed
as of the Termination Date) over such net sales proceeds. Upon payment by Lessee
of the amounts due pursuant to this Section 8(b), the obligation of Lessee to
pay Base Rent and Supplemental Rent, other than to pay Supplemental Rent
attributable to acts, events or conditions occurring or existing on or prior to
such termination with respect to such Transponders, shall terminate, such
Transponders shall no longer be subject to this Lease and the Lease Term with
respect to such Transponders shall end.

<PAGE>
 
     (c) Retention of Transponders by Lessor. If Lessee shall elect to terminate
         -----------------------------------
this Lease pursuant to Section 8(a), Lessor may, subject to Lessee's right to
cancel the proposed notice of termination, elect to retain rather than sell the
Transponders by giving irrevocable notice to Lessee and Indenture Trustee no
later than 45 days prior to the Termination Date. If Lessor so elects to retain
the Transponders, on the Termination Date (i) Lessor shall pay to Indenture
Trustee an amount equal to the unpaid principal amount of, and Premium, if any,
due on the outstanding Notes and (ii) Lessee shall pay to Lessor or the Person
entitled thereto as provided in the Operative Documents (A) (i) all Base Rent
with respect to the Transponders due prior to the Termination Date and (ii) in
the event that the Termination Date is a Rent Payment Date on which a Schedule
Rent payment designated as an "arrears rent" on Schedule A hereto as adjusted
pursuant to Section 4 is due, the sum of any Scheduled Rent with respect to the
Transponders designated as an "arrears rent" on Schedule A as adjusted pursuant
to Section 4 due on such Termination Date and the Rent Differential amount with
respect to such date, if any, and (B) all other Rent (other than any amounts
required to be paid by Lessee pursuant to the second sentence of Section 8(b))
due and owing on or prior to the Termination Date, including Premium, if any, on
the outstanding Notes, (iii) this Lease and the obligations of Lessee hereunder
shall terminate, other than to pay Supplemental Rent attributable to acts,
events or conditions occurring or existing on or prior to such termination, and
(iv) Lessor shall execute and deliver to Lessee, at Lessee's reasonable expense,
such instruments as Lessee shall reasonably request to evidence the termination
of this Lease. In the event Owner Participant fails to make funds available to
Owner Trustee to enable Lessor to pay the
 
                                      43
 
<PAGE>
 
amounts specified in clause (i) of this Section 8(c) or Lessee fails to pay the
amounts specified in clause (ii) of such sentence, Lessee shall be deemed to
have cancelled its notice of termination and the Lease shall continue in full
force and effect (and in the case of Lessor's failure to pay the amounts set
forth in clause (i), above, Lessee shall have the right to enforce the
obligations of Owner Participant as set forth in Section 5.02(j) of the
Participation Agreement). 


      (d) No Duplication of Rent Differential Amount. In the event that a
          ------------------------------------------
portion of the Scheduled Rent due on any Termination Date is designated as an
"arrears rent" on Schedule A and there is also a payment of Scheduled Rent due
on such Termination Date that is not so designated, a portion of the Rent
Differential Amount with respect to such Termination Date shall be added to the
Scheduled Rent designated as an "arrears rent" due on such date and the
remainder of such Rent Differential Amount shall be taken into account in the
computation of Termination Value pursuant to the definition of Termination
Value. It is intended that the entire amount of the Rent Differential Amount due
on such Termination Date shall be allocated between the Scheduled Rent
designated as an "arrears rent" due on such date and the computation of
Termination Value, as appropriate and without duplication, in such manner as
will preserve the Owner Participant's Net Economic Return and comply with the
minimum payment requirement (it being understood that the entire mount of such
Rent Differential Amount shall be taken into consideration in making such
allocation).

     SECTION 9. Insurance.
                ---------

          (a) Liability Insurance. Lessee shall not be required to obtain
              --------------------                                     
general liability insurance in respect of the Satellite or any of the
Transponders, unless it shall carry such insurance for similar events or
occurrences on other satellites or transponders it or any of its Affiliates owns
or leases from third parties, in which case it shall carry such liability
insurance on the Satellite or Transponder in the amount and on terms and for
similar events or occurrences and against risks comparable to those applicable
to such other satellites or transponders. Lessee shall not, however, have any
obligation to carry or continue to carry any such liability insurance on any
such other satellite or transponders. Lessee agrees that it shall not take any
action to induce any of its liability insurers to increase the premiums charged
for existing liability insurance with respect to the Transponders or to seek to
remove such Transponders from coverage under any such policy, unless Lessee, in
its discretion, shall determine that the premium paid for, or attributable to,
such general liability insurance is commercially unreasonable.

          (b)  Insurance Against Loss or Damage.
               --------------------------------

               (i) Requirement to Obtain and Maintain. During the Lease Term
                   ----------------------------------                     
     with respect to any Transponder, if at any time (a) the Moody's Credit
     Rating is Baa2 or lower or (b) the Standard & Poor's Credit Rating is BBB
     or lower or (c) GMHE's Tangible Net Worth is less than $3.5 billion, then
     within thirty (30) days following the date that Lessee shall have Actual
     Knowledge that any of the foregoing conditions exist, Lessee shall obtain
     and maintain, for the period that any such condition continues to exist,
     life or casualty insurance with respect to the Transponders, on standard
     industry terms and conditions, in an amount equal to

                                       45
 
<PAGE>
 
(x) Stipulated Loss Value for the Transponders from time to time without any
deductible; except that Lessee shall not be required to obtain such insurance if
Lessor in its sole discretion waives such requirement upon written request by
Lessee therefor. In addition, Lessor may in its sole discretion permit a
deductible upon written request by Lessee therefor. If at any time during the
Lease Term (A) the Notes are not rated Investment Grade by either of Moody's or
Standard & Poor's and (B) GMHE's Tangible Net Worth is less than $3.5 billion,
then, within thirty (30) days following the date that Lessee shall have Actual
Knowledge that the conditions described in clauses (A) and (B) exist, Lessee
shall obtain, for the period that both of such conditions continue to exist,
life or casualty insurance with respect to the Transponders, on standard
industry terms and conditions, in an amount, if any, equal to (x) Stipulated
Loss Value for the Transponders from time to time, subject to a deductible with
Lessor's written consent in an amount not greater than 1.5% of GHME's Tangible
Net Worth, as of the date of such insurance policy (with such deductible amount
being subject to re-adjustment on the expiration date for such policy, based on
the most recent public financial report of GMHE) (the "Permitted Deductible").
                                                       --------------------
If, at any time during the Lease Term, (1) the Moody's Credit Rating is Ba2 or
lower or (2) the Standard & Poor's Credit Rating is BB or lower or (3)
GMHE's Tangible Net Worth is less than $3 billion, then Lessee shall carry for
the period that any of the conditions described in clauses (1) or (2) or (3)
continues to exist, such policy for the full amount of Stipulated Loss Value for
the Transponders without any deductible.
 
                                      46
 
<PAGE>
 
     (ii) Non-Discrimination. At all times during the Lease Term, Lessee will
          ------------------
maintain life or casualty insurance in an amount and type for the Tramponders
that is not significantly different from the life or casualty insurance that
Lessee maintains, in its sole discretion, for comparable transponders owned or
operated by Lessee or its Affiliates; provided, however, that the foregoing
                                      --------  -------
shall not require Lessee to maintain life or casualty insurance for the
Transponders in an amount in excess of Stipulated Loss Value for such
Transponders subject to the Permitted Deductible.

    (iii) Letter of Credit. If at any time during the Lease Term, Lessee is
          ----------------
required to carry insurance against loss or damage for the Transponders, Lessee
may, in lieu of or in combination with, carrying such insurance, provide a
letter of credit from an Eligible Bank reasonably acceptable to Lessor, which in
combination with any insurance carried by Lessee, shall be in an amount
corresponding to the Stipulated Loss Value for the Transponders from time to
time (minus the Permitted Deductible or such other permitted deductible, if
applicable).

    (c) Additional Insureds. All insurance policies, if any, carried in
        -------------------
accordance with Section 9(a) and all policies taken out in substitution or
replacement for any such policies (i) shall name Lessor (in its individual
capacity and as Owner Trustee), Owner Participant, and Indenture Trustee, as
additional insureds, as their respective interests may appear (but without
imposing upon any such parties any obligation imposed upon the insured,
including, without limitation, the liability to pay the premium for such
policies) and in the case of life or casualty insurance pursuant to Section
9(b),

                                      47
<PAGE>
 
Indenture Trustee, and within 30 days after the Delivery Date Lessor, shall be
named as "loss payees", as their interests may appear; (ii) shall provide that
any loss (other than a loss under third party liability insurance) shall be
adjusted by the Lessee with the insurance carriers and be payable to the Lessor
(or, so long as the Indenture shall be in effect, the Indenture Trustee), for
application as provided in Section 12 hereof or Section 5.4 of the Indenture;
and (iii) shall provide that if such insurance is changed in any material
respect in relation to the interests of the Lessor or Owner Participant (and for
so long as the Indenture shall be in effect, Indenture Trustee), or if such
insurance is allowed to lapse for non-payment of premium, or is invalidated by
any action or inaction of Lessee or any other Person (other than action or
inaction by Lessor, Owner Participant or Indenture Trustee, as the case may be),
such change, lapse or invalidation shall not be effective as to Lessor, Owner
Participant and (so long as the Indenture shall be in effect) Indenture Trustee
for at least 30 days after receipt by Lessor, Owner Participant and (so long as
the Indenture shall be in effect) Indenture Trustee of written notice from such
insurers, their agents or the Lessee of such lapse. Each insurance policy
provided under this Section 9 shall be primary without right of contribution
from any other insurance which is carried by Lessor, Owner Participant or
Indenture Trustee with respect to their respective interests as such in the
Transponders.

     (d) Separate Insurance. Nothing contained in this Lease shall prevent
         ------------------
Lessor, Owner Participant, Indenture Trustee or Lessee, each at its own expense
and for its exclusive benefit, from carrying excess casualty insurance covering
the Transponders in addition to the casualty insurance, if any, carried by
Lessee under Section 9(b) (any such additional casualty insurance being herein
called "Additional Insurance"); provided,
                                --------

                                      48
<PAGE>
 
however, that Lessee shall not be entitled to obtain any such Additional
- --------                                                               
Insurance for the Transponders unless Lessee shall then maintain insurance for
such Transponders pursuant to Section 9(b) in an amount at least equal to the
Stipulated Loss Value for such Transponders from time to time set forth in
Schedule B corresponding to such date, subject to customary industry
deductibles or the deductibles permitted pursuant to Section 9(b), if
applicable. If there shall be any limitation with respect to the amount of
Additional Insurance that Lessor, Owner Participant, Indenture Trustee or Lessee
may obtain, whether as a result of market capacity or otherwise, then each such
party shall have the right to purchase an amount of Additional Insurance for the
Transponders as its interests may then appear. Prior to obtaining any Additional
Insurance, Lessor, Owner Participant or Indenture Trustee shall provide Lessee
with reasonable notice of the Additional Insurance (including the proposed terms
thereof) intended to be obtained by it, including evidence satisfactory to
Lessee that such proposed terms shall be consistent with the terms of such
insurance as may be carried by Lessee under Sections 9(a), 9(b)
or 9(c).

     SECTION 10. Redelivery.
                 ----------

          (a) Acceptable Redelivery. At the expiration or earlier termination of
              ---------------------                                          
the Lease Term with respect to any Transponder, if Lessee does not renew this
Lease with respect to such Transponder and does not purchase such Transponder,
Lessee shall at Lessee's cost and expense redeliver such Transponder to Lessor
on the Satellite in the condition required by Section 7 hereof and with the
Satellite (i) being located in an orbital location authorized by the FCC for the
remaining useful commercial life of the Satellite that is in the Authorized
Range, (ii) having been located in such orbital location

                                       49
<PAGE>
 
for a period of no less than the thirty (30) consecutive months prior to the
date of such Redelivery, (or being located at any other orbital location as a
result of an Emergency Move with no requirement that the Satellite be located in
such orbital location for any period of time) pursuant to an FCC authorization
which would allow it to remain in such orbital location for the Satellite's
remaining useful commercial life (this clause (ii), the "Residency
Requirement"), and (iii) meeting the Minimum Fuel Requirement (satisfaction of
the requirements set forth in clauses (i), (ii) and (iii) collectively being
referred to as an "Acceptable Redelivery"). If Lessee's Redelivery of any
Transponder is other than an Acceptable Redelivery, then the parties shall have
the rights and obligations set forth in Section 10(c) or Section 10(d). If an
Acceptable Redelivery is made, Lessor must accept such Redelivery, subject to
Section 10(b), and Lessee shall have no obligation under Section 10(c) or 10(d).

     (b) Redelivery Terms. In the event of any Redelivery of any Transponder,
         ----------------
Lessee shall execute and deliver to Lessor an instrument substantially in the
form of Exhibit C to this Lease that shall constitute evidence of surrender by
Lessee of all of Lessee's rights to such Transponder under this Lease and the
Hughes Agreements applicable thereto; provided, however, that Lessee's
                                      --------  -------
Redelivery of any Transponder hereunder shall not by itself affect the validity
and effectiveness of the Purchase Agreement, Service Agreement or any Substitute
Service Agreement relating to such Transponder, as applicable. At the time of
any Redelivery, such Transponder shall be free and clear of all Liens (other
than Permitted Liens described in clauses (a) and (b) of the definition thereof,
excluding Lessor Liens and Indenture Trustee Liens) and free and clear of any
right of any Person to use or access such Transponder other than Lessor

                                      5O
<PAGE>
 
or Owner Participant unless Owner Participant shall consent to a request by
Lessee to recognize any fight of any Person to use or access such Transponder
other than Lessor and Owner Participant; and Lessee shall be in compliance with
Sections 7(b) and (c).

     (c) Rejectable Offer. If at the time of Redelivery of any Transponder
         -----------------
(other than a Redelivery pursuant to Section 8), the Satellite will (A) fail to
meet the Minimum Fuel Requirement, or (B) be located in an orbital location
outside the Authorized Range other than as a result of the failure of STLC to
pursue in a commercially reasonable manner authority to locate the Satellite in
an orbital location within the Authorized Range or (C) not have been in its
orbital location at redelivery for a period of 30 consecutive months by reason
of an Emergency Move (an "Emergency Relocation") or an FCC Ordered Move; then,
as the remedy for its failure to make an Acceptable Redelivery, Lessee shall
make an offer to Lessor (the "Rejectible Offer"), no earlier than 540 days and
                              ----------------
no later than thirty (30) days prior to the scheduled date of such Redelivery,
to purchase such Transponder in lieu of Redelivery for a purchase price (the
"Offer Amount") equal to (i) 12% of Buyer's Cost for such Transponder if
 ------------
such Redelivery is at the end of the Basic Term or (ii) 2.4% of Buyer's Cost if
such Redelivery is at the end of the First Renewal Term. Lessor shall inform
Lessee whether it shall accept or reject such Rejectable Offer within ninety
(90) days of receipt of the Rejectable Offer if made 180 days or more prior to
the scheduled date of such Redelivery and within fifteen (15) days of receipt of
the Rejectable Offer if made less than 180 days prior to the scheduled date of
such Redelivery. If Lessor timely rejects the Rejectable Offer, or fails timely
to accept or reject such offer, then Redelivery of the Satellite shall occur at
the end of the Lease Term pursuant to Section 10(b) and such
 
                                      51
 
<PAGE>
 
Redelivery shall be deemed an Acceptable Redelivery. If Lessor timely accepts
the Rejectable Offer, then Lessee shall retain Control of the Transponders, and
pay the Offer Amount to Lessor on the last day of the Lease Term, together with
any and all Rent due and owing; and concurrently, Lessor shall transfer title to
such Transponder to Lessee as is, where is, free and clear of all Lessor Liens
and Owner Participant Liens, but otherwise without warranty, by executing and
delivering to Lessee an instrument substantially in the form of Exhibit C to the
Lease.

     If Lessee does not purchase the Subsequent Purchase Option on or before the
Subsequent Purchase Option Cut-off Date, and subsequent thereto (during the
Lease Term), Lessee makes an Emergency Move of the Satellite, any Redelivery of
the Transponders at the termination of the Lease Term shall occur at the
orbital location at which the Satellite was located immediately prior to such
Emergency Move (unless Lessor, in its sole discretion, shall consent to
Redelivery to another orbital location, then to such other location), and the
parties shall otherwise have the rights and obligations with respect to such
Redelivery as set forth in Section 10(c).


     (d) Rejectable Offer; Decreased Value. If at the time of Redelivery of any
         ---------------------------------
Transponder (other than a Redelivery pursuant to Section 8), the Satellite
will (A) fail to meet the Residency Requirement for any reason other than an
Emergency Relocation or an FCC Ordered Move or (B) be outside the Authorized
Range due to the failure of STLC to pursue in a commercially reasonable manner
authority to locate the Satellite in an orbital location for the Satellite
within the Authorized Range, then, as the remedy for its failure to make an
Acceptable Delivery, Lessee shall make the Rejectable Offer to Lessor in
accordance with the immediately preceding paragraph,
 
                                      52
 
<PAGE>
 
except that if Lessor timely rejects the Rejectable Offer or fails timely to
accept or reject such offer, then (1) Redelivery of the Satellite shall occur at
the end of the Lease Term pursuant to Section 10(b), and (2) as the remedy for
its failure to make an Acceptable Delivery Lessee shall pay to Lessor the
Decreased Value Payment upon the later of the Reclelivery date or five (5) days
after the Decreased Value of such Transponder is determined in accordance with
the Appraisal Procedure (which procedure shall commence not later than 120 days
prior to Redelivery if the existence of a condition requiring a payment of
Decreased Value is ascertainable at such time or as soon thereafter as is
reasonably possible if it not so ascertainable). If Lessor timely accepts the
Rejectable Offer, then Lessee shall retain Control of the Transponders, and pay
the applicable Offer Amount to Lessor on the last day of the Lease Term,
together with any and all Rent due and owing; and concurrently, Lessor shall
transfer title to such Transponder to Lessee as is, where is, free and clear
of all Lessor Liens and Owner Participant Liens, but otherwise without any
warranty, by executing and delivering to Lessee an instrument substantially in
the form of Exhibit C to the Lease.

      As used herein, "Minimum Fuel Requirement" shall mean that amount of fuel
which is reasonably determined by Lessee (after consultation, if requested by
Lessor, with an appraiser who is qualified to conduct the Appraisal Procedure
and utilizing the same measurement techniques generally used by it in connection
with making such determinations) to be sufficient to cause the Satellite to have
a total useful commercial life of 15 years as measured from the Delivery Date.
As used herein, "Decreased Value" shall mean an amount equal to the decreased
value of any Transponder as of the Redelivery date due to the decrease in such
Transponder's Fair Market Sales Value
 
                                      53
 
<PAGE>
 
compared with what such value would be as of such date if the event or condition
giving rise to such decreased value had not occurred. As used herein, "Decreased
Value Payment" shall mean a payment in an amount equal to the applicable
Decreased Value.

          (e) Assumption of Certain Subleases. Upon Lessor's acceptance of a
              -------------------------------                             
Rejectable Offer made in respect of a Transponder pursuant to Section 10(c) or
10(d). Lessee shall assume any sublease or use agreement for the use of such
Transponder entered into by Owner Participant or Lessor (provided it has been
entered into in an arm's length transaction with a non-affiliated third party on
terms and conditions customary in the transponder leasing industry) after the
Preliminary Notice Expiration Date without such Preliminary Notice having been
delivered with respect to such Transponder and prior to the Rejectable Offer
having been made by Lessee (the "Acceptable Interim Contracts"). As a condition
to Lessee's obligation to assume any such Acceptable Interim Contract, Lessor
shall pay to Lessee any and all payments of any type it has received on account
of such Acceptable Interim Contract net of any reasonable out-of-pocket expenses
or costs incurred by Lessor or Owner Participant associated therewith.
Notwithstanding the provisions of this Section 10(e), Lessor and Owner
Participant shall not be entitled to any indemnity or reimbursement of any costs
or expenses that are not directly attributable to obtaining any Acceptable
Interim Contract or the provision of services on the related Transponder
pursuant to the Acceptable Interim Contracts. Lessee shall indemnify and hold
Owner Participant and Lessor harmless against all claims, costs or expenses
reasonably incurred in connection with an Acceptable Interim Contract, not
including any claims, costs or expenses incurred as a result of a wrongful act
by Lessor or Owner Participant. Lessor and Owner

                                      54
<PAGE>
 
Participant shall indemnify and hold harmless Lessee against all other claims,
costs or expenses arising from any affirmative actions by Lessor or Owner
Participant to market or otherwise utilize any such Transponder. Lessee shall,
at the request of the Lessor or Owner Participant, furnish forms of transponder
leases currently in use by Lessee or its Affiliates, and contracts containing
all of the substantive provisions of such form and which are substantially
identical in all other respects shall be deemed to comply with the requirements
of the first sentence of this Section 10(e).

          (f) Redelivery in Connection with Termination. If at the time of a
              -----------------------------------------
termination of the Lease under Section 8(a) with respect to any Transponder, or
retention of any Transponder by Lessor in accordance with Section 8(c), such
Transponder does not meet the requirements for an Acceptable Redelivery, Lessee
shall pay to Lessor, in addition to the other amounts required under Section 8
of the Lease, (A) in the case of a termination of the Lease with respect to such
Transponder pursuant to Section 8(a), the Decreased Value Payment with respect
to such Transponder to the extent that the Fair Market Sales Value of such
Transponder exceeds the higher of (i) the proceeds of any sale of such
Transponder and (ii) Termination Value for such Transponder; provided that no
                                                             -------- ----
such Decreased Value Payment shall be due under this Section 8(f) if the Fair
Market Sales Value of such Transponder is less than or equal to Termination
Value for such Transponder, and (B) in the case of a retention of such
Transponder by Lessor in accordance with Section 8(c), an amount equal to the
amount, if any, by which the Fair Market Sales Value of such Transponder exceeds
the higher of (i) the fair market sales value of such Transponder and (ii) the
Termination Value of such Transponder.

     SECTION 11. Cooperation.
                 -----------

          (a) Lessor's Efforts to Sell or Lease. Lessee agrees that during the
              ---------------------------------                             
last 540 days of the Basic Term or any Renewal Term applicable to any
Transponder (unless Lessee has provided Lessor with the Final Notice stating
that it will renew the Lease or purchase such Transponder, pursuant to Sections
18 or 19, respectively, and in such case no Bankruptcy Default or Event of
Default shall have occurred and be continuing), it will cooperate in all
reasonable respects with efforts of Lessor to lease or sell such Transponder,
including aiding potential lessees or purchasers by providing all data relating
to maintenance and performance for inspection which Owner under the Service
Agreement and Buyer under the Purchase Agreement are entitled to receive or
inspect subject to any confidentiality requirement set forth in such agreements.
Further, Lessee shall notify existing users of such Transponder of the end of
the Lease Term and use best reasonable efforts to assist Lessor in obtaining any
necessary regulatory approvals to operate, lease or sell such Transponder, at
Lessor's reasonable cost and expense, on an After-Tax Basis to Lessee. In
addition, Lessee shall furnish to Lessor such information as it supplies to
potential lessees or purchasers of transponders that it owns or leases on the
Satellite or other similar satellites.

          (b) Value and Useful Life Determinations. Lessee shall provide Lessor
              ------------------------------------
at any time with information which, in the reasonable opinion of Lessor, is
necessary or material for Lessor to negotiate and reach an agreement for any
determination of Fair Market Sales Value, Fair Market Rental Value and estimated
remaining useful commercial life; provided, however, that Lessee shall not be 
                                  --------  -------
required to disclose

                                       56
<PAGE>
 
confidential information unrelated to the performance or maintenance of the
Transponders.

     SECTION 12. Loss, Destruction, Condemnation or Damage.
                 -----------------------------------------

          (a) Payment of Stipulated Loss Value. If with respect to any
              --------------------------------
Transponder an Event of Loss occurs, then Lessee shall forthwith (and, in any
event, within seven (7) days of such occurrence) give Lessor and Indenture
Trustee notice of such Event of Loss (the "Casualty Notice"), which notice
shall include, if applicable, Lessee's election to provide a Replacement
Transponder in accordance with the last sentence of this paragraph and shall
also state whether the proviso to this sentence shall be applicable by reason of
the Lessee having in force insurance against loss or damage to the
Transponders, pursuant to Section 9(b) or voluntarily, and on the Casualty
Payment Date first occurring not less than 30 days after the date of such
notice, Lessee shall pay to Lessor an amount equal to the sum of (x) the
Stipulated Loss Value for the Transponder due on such Casualty Payment Date and
(y) the sum of (A) all amounts of Interim Rent and Base Rent with respect to
such Transponder due and unpaid prior to such Casualty Payment Date, and (B)(i)
at any time during the Interim Term or the Basic Term, in the event that the
Casualty Payment Date is a Rent Payment Date on which a Scheduled Rent payment
designated as an "arrears rent" on Schedule A hereto as adjusted pursuant to
Section 4 is due, the sum of Scheduled Rent with respect to such Transponder
designated as an "arrears rent" on Schedule A hereto as adjusted pursuant to
Section 4 and due on such Casualty Payment Date and the Rent Differential Amount
with respect to such date, if any, or (ii) at any time during a Renewal Term any
Base Rent due on such Casualty Payment Date and (C) any other Rent with respect
to such

                                       57
<PAGE>
 
Transponder due and unpaid as of such Casualty Payment Date; provided,
                                                             --------
however, that if, with respect to such Transponder, Lessee shall have in
- -------
force insurance against loss or damage to the Transponders, pursuant to
Section 9(b) or voluntarily, then subject to the provisions of Section 12(b),
Lessee shall pay to Lessor in immediately available funds on the Casualty
Payment Date first occurring not less than thirty (30) days after the date of
the Casualty Notice, the amount specified in clause (x) of this Section less the
amount of such insurance with respect to such Transponder and, within ten (10)
days after receipt of any such insurance proceeds (but in no event later than
120 days after the date of such Casualty Notice) the amount specified in clause
(x) of this Section to the extent not previously paid, and to the extent of any
such payment to be made from such insurance proceeds or otherwise after the
Casualty Payment Date referred to above, Lessee shall pay interest from such
Casualty Payment Date on such amount to but excluding the date of payment at the
highest interest rate payable on the Notes, if any Notes are then outstanding,
and otherwise at the Prime Rate. In lieu of making the foregoing payment, and so
long as, but only so long as, no Bankruptcy Default or Event of Default has
occurred and is continuing, Lessee may, at its option, notify Lessor and
Indenture Trustee of its intent to, and thereafter provide Lessor (on the
Casualty Payment Date first occurring not less than thirty (30) days after the
date of the Casualty Notice) with a Replacement Transponder, in accordance with,
and subject to, the provisions and the conditions in Section 7(e); provided,
                                                                   --------
further that, in the case of an Event of Loss of the type described in clause
- -------
(f) of the definition thereof, the amount due on the applicable Casualty Payment
Date in accordance with clause (x) of this Section 12(a) shall be the

                                      58
<PAGE>
 
  higher of Stipulated Loss Value and the Fair Market Sales Value for the
  Transponder on such Casualty Payment Date.

          Upon payment in full of all amounts due or the provision of a
  Replacement Transponder pursuant to the preceding paragraph, Lessor (as
  seller) shall transfer the Transponder suffering such Event of Loss to Lessee,
  the obligation of Lessee to pay Interim Rent and Base Rent with respect to
  such Transponder shall terminate, but shall continue as to any Replacement
  Transponder, such Transponder shall no longer be subject to this Lease and the
  Lease Term with respect to such Transponder shall end, but shall apply to any
  Replacement Transponder.

          (b) Application of Payments upon an Event of Loss. Subject to the
              ---------------------------------------------
  provisions of Section 12(d), and notwithstanding any rights of Lessor as owner
  of the Transponders, any payments received at any time by Lessor from any
  Governmental Body or other Person as a result of the occurrence of an Event of
  Loss with respect to a Transponder (including proceeds with respect to such
  Transponder from insurance, if any, but excluding proceeds from Additional
  Insurance with respect to such Transponder carried by Lessor, Owner
  Participant or Indenture Trustee) shall be applied as follows:

              (i) so much of such payments as shall not exceed the amount, if
     any, required to be paid with respect to such Transponder by Lessee
     pursuant to Section 12(a) shall be applied in reduction of Lessee's
     obligation to pay such amount with respect to such Transponder if not
     already paid by Lessee, or, if already paid with respect to such
     Transponder by Lessee, shall be applied to reimburse Lessee for its payment
     of such amounts, or if Lessee shall have provided Lessor with a Replacement
     Transponder pursuant to Section 12(a), shall

                                      59
<PAGE>
 
     be paid to Lessee upon conveyance of such Replacement Transponder to
     Lessor; and

              (ii) the excess, if any, of such payments with respect to such
     Transponder remaining thereafter, shall be paid to and retained by Lessee,
     except that any such excess received in connection with an Event of Loss as
     defined in clauses (b) or (d) of the definition of Event of Loss will be
     allocated between Lessor and Lessee as their respective interests may
     appear.

          (c) Application Of Payments Not Relating to an Event of Loss. In the
              --------------------------------------------------------
event of any loss, condemnation, confiscation, theft or seizure of, or use of,
or damage to, any portion of any Transponder not constituting an Event of Loss,
Lessee shall promptly notify Lessor and Indenture Trustee and all of Lessee's
obligations under this Lease with respect to such Transponder shall continue to
the same extent as if such event had not occurred. Subject to the provisions of
Section 12(d), and notwithstanding any implicit or express rights of Lessor as
owner of such Transponder, payments received at any time by Lessor or Lessee
from any insurer under insurance carried by Lessee from any Governmental Body or
from any other Person with respect to any loss, condemnation, confiscation,
theft or seizure of, or use of, or damage to, any Transponder or any part
thereof not constituting an Event of Loss shall be paid to Lessor or Lessee, as
their interests may appear.

          (d) Applications During Default. Any amount which may become payable
              ---------------------------
to Lessee pursuant to this Lease arising out of any insurance, warranty,
governmental award or otherwise shall not be paid to Lessee, or if it shall have
been paid to Lessee shall not be retained by Lessee, but shall be paid to Lessor
or Indenture

                                      60
<PAGE>
 
Trustee, as the case may be, if at the time of such payment a Payment Default,
Bankruptcy Default or an Event or Default shall have occurred and be continuing.
In such event, all such amounts shall be paid to and held by Lessor or, to the
extent required by the Indenture, Indenture Trustee, in trust as security for
the obligations of Lessee or Contractor to make payments under this Lease and
any other Operative Document or Hughes Agreement or to pay Rent hereunder or, at
the option of such holder, applied by such holder toward payment of any such
obligations of Lessee or Contractor at the time due hereunder or under such
other Operative Document or Hughes Agreement. At such time as there shall not be
continuing a Payment Default. Bankruptcy Default or an Event of Default all such
amounts at the time held by Lessor or Indenture Trustee, as the case may be, in
excess of the amount, if any, which Lessor or Indenture Trustee, as the case may
be, shall have elected to apply as above provided shall be paid to Lessee or
Contractor, as appropriate.

          (e) No Duplication of Rent Differential Amount. In the event that a
              ------------------------------------------
portion of the Scheduled Rent due on any Casualty Payment Date is designated as
an "arrears rent" on Schedule A and there is also a payment of Scheduled Rent
due on such Casualty Payment Date that is not so designated, a portion of the
Rent Differential Amount with respect to such Casualty Payment Date shall be
added to the Scheduled Rent designated as an "arrears rent" due on such date and
the remainder of such Rent Differential Amount shall be taken into account in
the computation of Stipulated Loss Value pursuant to the definition of
Stipulated Loss Value. It is intended that the entire amount of the Rent
Differential Amount due on such Casualty Payment Date shall be allocated between
the Scheduled Rent designated as an "arrears rent" due on such date
 
                                      61
<PAGE>
 
and the computation of Stipulated Loss Value, as appropriate and without
duplication, in such manner as will preserve the Owner Participant's Net
Economic Return and comply with the minimum payment requirement (it being
understood that the entire amount of such Rent Differential Amount shall be
taken into consideration in making such allocation).

     SECTION 13. Merger, Consolidation.
                 ---------------------

          Neither STLC nor GMHE shall consolidate with or merge into any other
Person or convey, transfer or lease all or substantially all of its assets as an
entirety to any Person, unless:

               (i)    the successor entity formed by such consolidation or into
     which it is merged or the successor entity which acquires by conveyance,
     transfer or lease all or substantially all of its assets as an entirety
     shall be a corporation organized and existing under the laws of the United
     States of America, any State thereof or the District of Columbia which has
     a substantial part of its properties and assets located within and operates
     substantially within, the United States of America, and which is qualified
     under the requirements of the FCC and any applicable statute, regulation or
     order to assume STLC's or GMHE's, as the case may be, obligations with
     respect to the Satellite and/or Transponders then subject to this Lease;

               (ii) such successor corporation shall expressly assume in writing
     by instrument or instruments enforceable against it reasonably satisfactory
     in form and substance to Lessor and Owner Participant the due and punctual
     payment, performance and observance of all obligations of STLC or GMHE, as
     the case
                                       62
<PAGE>
 
     may be, under this Lease and any other Operative Document or Hughes
     Agreement to which STLC or GMHE, as the case may be, is a party in any
     capacity, with the same effect as if such corporation had originally been
     named Lessee herein or had been a party thereto;

               (iii) immediately after giving effect to such transaction, no
     Bankruptcy Default or Event of Default shall exist and the Guarantee
     Agreement (or any successor agreement) shall be in full force and effect;
     and

               (iv) STLC or GMHE, as the case may be, shall have delivered to
     Lessor, Owner Participant and Indenture Trustee an opinion of counsel in
     scope and substance reasonably satisfactory to each stating that such
     consolidation, merger, conveyance, transfer or lease and the assumption
     agreement required by clause (ii) above comply with this Section 13.

          Upon any consolidation or merger, or any conveyance, transfer or lease
of all or substantially all of the assets of STLC or GMHE, as the case may be,
as an entirety in accordance with this Section 13, the successor corporation
formed by such consolidation or into which STLC or GMHE, as the case may be, is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, Lessee under
the Operative Documents to which STLC or GMHE, as the case may be, is a party in
any capacity with the same effect as if such successor corporation had been
named Lessee herein and thereto. No such conveyance, transfer or lease of all or
substantially all of the assets of STLC or GMHE, as the case may be, as an
entirety shall have the effect of releasing STLC or GMHE, as the case may be, or
any successor corporation which shall theretofore have become such

                                       63
<PAGE>
 
in the manner prescribed in this Section 13 from its liability hereunder or
under the other Operative Documents or Hughes Agreement to which STLC or GMHE,
as the case may be, is a party in any capacity.

     SECTION 14. Reports.
                 -------

          (a) Condition and Operation. Lessor, Owner Participant and Indenture
              -----------------------
Trustee shall have the right to obtain and, following any such request by any of
them, Lessee shall provide or request to be provided, information regarding the
condition and state of repair of any Transponder then subject to this Lease,
compliance by Lessee with Sections 7 and 9 and performance of Seller and
Contractor under the Hughes Agreements (it being understood that information
with respect to the performance of Seller and Contractor shall be limited to
that made available pursuant to the Hughes Agreements), and the absence of any
Default, or Event of Default or Event of Loss, or event which with the passage
of time or giving of notice or both would become an Event of Loss. Indenture
Trustee shall neither have any duty to make any inquiry nor incur any liability
obligation by reason of not making any such inquiry.

          (b) Liens. Lessee shall promptly (and in no event later than five (5)
              -----
Business Days) notify Lessor and Indenture Trustee after having obtained Actual
Knowledge of the attachment of any Lien which Lessee shall be obligated to
discharge or eliminate pursuant to Section 6 unless the same shall already have
been removed or discharged by Lessee.

                                       64
<PAGE>
 
     SECTION 15. Events of Default.
                 ------------------

          Each of the following events shall constitute an Event of Default
(whether any such event shall be voluntary or involuntary or come about or be
effected by operation of law or pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation of any
Governmental Body):

          (a) Lessee shall fail to make any payment of Interim Rent, Base Rent,
Supplemental Rent pursuant to Section 3(b)(i)(A) or Section 3(c)(ii),
Termination Value or Stipulated Loss Value when due and such failure shall
continue ten (10) Business Days; or

          (b) Lessee shall fail to make any other payment of Rent when due and
such failure shall continue ten (10) Business Days after written notice thereof
by Lessor (or Indenture Trustee); or

          (c) Other than with respect to any covenant of Lessee set forth in
Section 15.02(b) of the Participation Agreement and Article X and Annex A of the
Participation Agreement, Lessee shall fail to perform or observe in any material
respect any covenant, condition or agreement to be performed or observed by it
under this Lease (other than Section 9(b)), or Guarantor shall fall to perform
or observe in any material respect any covenant, condition or agreement to be
performed or observed by it under the Participation Agreement or the Guarantee
Agreement or Lessee shall fail to perform or observe in any material respect any
other covenant, condition or agreement to be performed or observed by it under
any of the other Operative Documents to which it is a party (other than any such
covenant, condition or agreement under the Tax Indemnification Agreement not
related to the payment of money thereunder, provided
                                            --------

                                       65
<PAGE>
 
that the declaration of an Event of Default hereunder with respect to any such
- ----
covenant, condition or agreement shall be only upon the instructions of the
Owner Participant) and, in each such case, such failure shall have continued for
ninety (90) days after Lessee's receipt of written notice thereof from Lessor or
Indenture Trustee; provided, however, that if such failure is capable of cure
                   --------  -------
but cannot be cured by payment of money and cannot be cured by diligent efforts
within such 90-day period but such diligent efforts shall be properly commenced
within the cure period and Lessee is diligently pursuing, and shall continue to
pursue diligently, a remedy of such failure, the cure period shall be extended
for an additional period of time as may be necessary to cure, not to exceed 90
days; or

      (d) any representation or warranty made by STLC, GMHE or Contractor in any
of the Operative Documents or Hughes Agreements to which it is a party or in any
written statement, report, schedule, notice or other writing furnished by STLC,
GMHE or Contractor in connection therewith (other than any representation or
warranty under the Tax Indemnification Agreement) shall prove to have been
inaccurate in any material respect at the time made; provided, however, that if
                                                     --------  ------- 
the representation or warranty was originally made in good faith, an Event of
Default shall not be deemed to exist unless the inaccuracy materially adversely
affects Lessor or Owner Participant and if capable of being cured, remains
uncured for a period of ninety (90) days after receipt by Lessee of written
notice from Lessor of such inaccuracy; provided, however, that if such Default
                                       --------  -------
cannot be cured by payment of money and cannot be cured by diligent efforts
within such 90-day period but such diligent efforts shall be properly commenced
within the cure period and Lessee is diligently pursuing, and shall continue

                                      66
<PAGE>
 
to pursue diligently, a remedy of such failure, the cure period shall be
extended for an additional period of time as may be necessary to cure, not to
exceed 90 days; or

          (e) The Guarantee Agreement shall cease to be valid and binding or in
full force or effect; or

          (f) STLC or GMHE shall consent to the appointment of, or taking of
possession by, a receiver, trustee, custodian or liquidator of itself or of a
substantial part of its property, or shall fail to pay its debts generally as
they become due, or shall make a general assignment for the benefit of
creditors; or

          (g) STLC or GMHE shall file a voluntary petition in bankruptcy or a
voluntary petition or an answer seeking reorganization in a proceeding under any
applicable bankruptcy or insolvency laws (as now or hereafter in effect) or an
answer admitting the material allegations of a petition filed against such
Person in any such proceeding, or shall by voluntary petition, answer or
consent, seek relief under the provisions of any now existing or future
bankruptcy, insolvency or other similar law providing for the liquidation,
reorganization or winding-up of corporations, or providing for an agreement,

or proceeding shall not be dismissed within ninety (90) days after filing; or

     SECTION 16. Remedies.
                 --------

          Upon the occurrence of any Event of Default and at any time thereafter
so long as the same shall be continuing, Lessor may at its option declare this
Lease to be in default, and at any time thereafter Lessor may do any of the
following as Lessor in its sole discretion shall elect, to the extent permitted
by, and subject to compliance with any mandatory requirements of, Applicable
Law then in effect:

          (I) Proceed by appropriate court action, either at law or in equity,
to enforce performance by Lessee or Guarantor of the applicable covenants of
this Lease or Guarantee Agreement or to recover damages for the breach thereof;
or

          (II) By notice in writing terminate this Lease, whereupon all rights
of Lessee to the use of the Transponders shall absolutely cease and terminate
but Lessee shall remain liable as hereinafter provided;

               (a) (i) Lessor, by notice to Lessee specifying a payment date not
     later than 180 days from the date of such notice, may require Lessee to pay
     to Lessor, and Lessee hereby agrees that it will pay to Lessor, on the
     payment date specified in such notice, as liquidated damages for loss of a
     bargain, and not as a penalty, and in lieu of any further payments of
     Interim Rent or Base Rent hereunder, an amount (reduced by any amounts
     previously paid by Lessee
                                       68
<PAGE>
 
     pursuant to Section 16(II)(c)) equal to the sum of (x) all unpaid Interim
     Rent or Base Rent payable or which would have been payable before the
     Casualty Payment Date next succeeding the date of payment specified in such
     notice and (y)(A) at any time during the Interim Term or the Base Term, in
     the event that the Casualty Payment Date is a Rent Payment Date on which a
     Scheduled Rent designated as an "arrears rent" on Schedule A hereto as
     adjusted pursuant to Section 4 is due, the sum of Scheduled Rent designated
     as an "arrears rent" in Schedule A hereto as adjusted pursuant to Section 4
     due on such Casualty Payment Date with respect to the Transponders and the
     Rent Differential Amount, if any, or (B) at any time during a Renewal Term,
     any Base Rent due on such Casualty Payment Date and (z) an amount equal to
     the Stipulated Loss Value for the Transponders calculated as of such
     Casualty Payment Date next succeeding the date of payment specified in such
     notice (unless such payment date occurs on a Casualty Payment Date, in
     which case such Stipulated Loss Value and such unpaid Interim Rent and Base
     Rent shall be Computed as of such Casualty Payment Date), together with
     interest, if any, at the Overdue Rate on the amount of such Interim Rent
     and Base Rent and Stipulated Loss Value from the date as of which such
     Stipulated Loss Value is computed until the date of actual payment; and
     upon such payment of liquidated damages and all other Rent then due and
     payable by the Lessee hereunder, Lessor shall transfer the Transponders
     (without any representation, recourse or warranty whatsoever, other than
     the absence of Lessor Liens or Owner Participant Liens) to Lessee and
     Lessor shall execute and deliver such documents evidencing such Transfer as
     Lessee shall reasonably

                                      69
<PAGE>
 
     request, and Lessee shall indemnify Lessor on an After-Tax Basis for
     Lessor's reasonable expenses incurred in connection with such Transfer.

          (b) Lessor or its agent may sell the Transponders at public or private
     sale, as Lessor may determine, or otherwise may dispose of, hold, use,
     operate, keep idle, lease (whether for a period greater or less than the
     balance of what would have been the Basic Term or any Renewal Term, as the
     case may be) to others the Transponders, all on such terms and conditions
     and at such place or places as Lessor may determine and all free and clear
     of any rights of Lessee and of any claim of Lessee, in equity, at law or by
     statute, whether for loss or damage or otherwise and Lessee shall use its
     best efforts to obtain or assist Lesso r in obtaining, any necessary
     regulatory approvals for Lessor to take any action pursuant to this Section
     16(II)(b); provided, however, that (i) if Lessor or its agent shall sell
                --------  -------
     any Transponders, Lessee's obligation to pay Interim Rent and Base Rent
     with respect to any such Transponder sold hereunder for any period after
     the date of such sale shall terminate and such Transponder shall cease to
     be subject to this Lease from and after the date of such sale, and (ii)
     Lessee's obligation to pay Interim Rent and Base Rent for any period after
     Lessee shall have been deprived of control of the Transponder pursuant to
     clause (i) of this Section 16(II)(b) shall be reduced by the net proceeds,
     if any, received by Lessor from leasing the Transponder to, or otherwise
     permitting its use by, any Person other than Lessee fairly attributable to
     all or any portion of such period. In the event Lessor shall have sold any
     Transponder pursuant to this Section 16(II)(b) (and prior thereto shall not
     have exercised its rights under Section 16(II)(c)

                                      7O
<PAGE>
 
     hereof), Lessor may demand that Lessee pay Lessor and Lessee shall pay to
     Lessor, as liquidated damages for the loss of a bargain and not as a
     penalty, in lieu of all Interim Rent or Base Rent due after the date on
     which such sale occurs, an amount equal to the sum of (i) all unpaid
     Interim Rent and Base Rent payable or which would have been payable on or
     before the Casualty Payment Date next succeeding the date on which the sale
     occurs (unless such sale occurs on a Casualty Payment Date, in which case
     Interim Rent or Base Rent shall be computed as of such Casualty Payment
     Date) plus (ii) the amount, if any, by which the Stipulated Loss Value for
     such Transponder, computed as of the Casualty Payment Date immediately
     following the date on which such sale occurs (unless such sale occurs on a
     Casualty Payment Date, in which case as of such Casualty Payment Date),
     exceeds the net proceeds of such sale (together with interest, if any, at
     the Overdue Rate on the amount of such Interim Rent and Base Rent and
     deficiency from the Casualty Payment Date as of which such Stipulated Loss
     Value is computed until the date of actual payment).

          (c) Whether or not Lessor shall have exercised, or shall thereafter at
     any time exercise, any of its fights under Section 16(II)(b) hereof (other
     than a sale under Section 16(II)(b) hereof), Lessor may, at any time prior
     to the time that any Transponder shall have been sold or leased by Lessor
     pursuant to Sections 16(II)(a) or 16(II)(b) hereof, by written notice to
     Lessee requesting that the fair market sales value or fair market rental
     value of such Transponder be determined, demand that Lessee pay to Lessor,
     and Lessee shall pay to Lessor on the first Casualty Payment Date occurring
     at least ten (10) days

                                      71

     after the determination of such fair market sales value or fair market
     rental value, each determined on an as is, where is basis, as the case may
     be, as liquidated damages for loss of a bargain and not as a penalty (in
     lieu of all payments of Interim Rent and Base Rent with respect to such
     Transponder becoming due for periods after the payment date), an amount
     equal to the sum of (i) all unpaid Interim Rent and Base Rent due before
     such Casualty Payment Date and (ii)(A) at any time during the Interim Term
     or the Basic Term, in the event that the Casualty Payment Date is a Rent
     Payment Date on which a Scheduled Rent designated as an "arrears rent" on
     Schedule A hereto as adjusted pursuant to Section 4 is due, the sum of
     Scheduled Rent designated as an "arrears rent" in Schedule A hereto as
     adjusted pursuant to Section 4 due on such Casualty Payment Date with
     respect to such Transponder and the Rent Differential Amount, if any, or
     (B) at any time during a Renewal Term, any Base Rent due on such Casualty
     Payment Date, and (iii) whichever of the following amounts Lessor in its
     sole discretion, shall specify in such notice (together with interest on
     such amount at the Overdue Rate from the scheduled payment date to the date
     of actual payment): (x) an amount equal to the excess, if any, of the
     Stipulated Loss Value, computed as of such Casualty Payment Date, over the
     fair market rental value for such Transponder, valued on an as is, where is
     basis for the remainder of the Interim Term and the Basic Term or the
     remainder of the Renewal Term as the case may be, after discounting such
     fair market rental value semi-annually (effective on the Rent Payment
     Dates) to present value as of the scheduled payment date at the rate of
     interest equal to the Overdue Rate; (y) an amount

                                      72
<PAGE>
 
     equal to the excess, if any, of such Stipulated Loss Value as of such
     Casualty Payment Date over the fair market sales value of such Transponder
     valued on an as is, where is basis or (z) an amount equal to the excess, if
     any, of (A) the present value computed as of such Casualty Payment Date of
     all installments of Scheduled Rent for the remainder of the Interim Term
     and Basic Term or Base Rent for the remainder of the Renewal Term, as the
     case may be, discounted semi-annually (effective on the Rent Payment Dates)
     to present value as of the scheduled payment date at the rate of interest
     equal to the Overdue Rate over (B) the present value, computed as of such
     Casualty Payment Date, of the fair market rental value of the Transponder
     for the remainder of the Interim Term and the Basic Term or of the Renewal
     Term, as the case may be, discounted semi-annually (effective on the Rent
     Payment Dates) to present value as of the scheduled payment date at the
     rate of interest equal to the Overdue Rate.

          (d) For all purposes of this Section 16, in the event that a portion
     of the Scheduled Rent due on any Casualty Payment Date is designated as an
     "arrears rent" on Schedule A and there is also a payment of Scheduled Rent
     due on such Casualty Payment Date that is not so designated, a portion of
     the Rent Differential Amount with respect to such Casualty Payment Date
     shall be added to the Scheduled Rent designated as an "arrears rent" due on
     such date and the remainder of such Rent Differential Amount shall be taken
     into account in the computation of Stipulated Loss Value pursuant to the
     definition of Stipulated Loss Value. It is intended that the entire amount
     of the Rent Differential Amount due on such Casualty Payment Date shall be
     allocated between the

                                      73
<PAGE>
 
     Scheduled Rent designated as an "arrears rent" due on such date and the
     computation of Stipulated Loss Value, as appropriate and without
     duplication in such manner as will preserve the Owner Participant's Net
     Economic Return and comply with the minimum payment requirement (it being
     understood that the entire amount of such Rent Differential Amount shall be
     taken into consideration in making such allocation).

All determinations of fair market sales value and fair market rental value
pursuant to this Section 16 shall be determined pursuant to the Appraisal
Procedure. No termination of this Lease, in whole or in part, or exercise of any
remedy under this Section 16 shall, except as specifically provided herein,
relieve Lessee of any of its liabilities and obligations hereunder, all of which
shall survive such termination, repossession or exercise of remedy. In addition,
Lessee shall be liable for any and all unpaid Supplemental Rent due hereunder
before, after or during the exercise of any of the foregoing remedies, including
all reasonable legal fees and other costs and expenses reasonably incurred by
Lessor, Owner Participant or Indenture Trustee by reason of the occurrence of
any Event of Default or the exercise of Lessor's remedies with respect thereto.
At any sale of the Transponders or any part thereof pursuant to this Section
16, Lessor, Owner Participant or Indenture Trustee may bid for and purchase
such property.

      Notwithstanding any provision in this Lease or any other Operative
Document, Lessee shall not cease to have the legal right to access any of the
Transponders unless and until Lessor shall give Lessee and Seller, at the time
when a notice of termination is given under the first sentence of clause (II)
above, 24 hours notice expressly demanding that Lessee surrender such right.

     To the extent permitted by, and subject to the mandatory requirements of,
Applicable Law, and except as otherwise specifically provided for in this Lease,
each and every right, power and remedy herein specifically given to Lessor or
otherwise in this Lease shall be cumulative and shall be in addition to every
other right, power and remedy herein specifically given or now or hereafter
existing at law, in equity or by statute, and each and every right, power and
remedy whether specifically herein given or otherwise existing may be exercised
from time to time and as often and in such order as may be deemed expedient by
Lessor, and the exercise or the beginning of the exercise of any power or remedy
shall not be construed to be a waiver of the right to exercise at the same time
or thereafter any other right, power or remedy. No delay or omission by Lessor
in the exercise of any right, remedy or power or in the pursuit of any remedy
shall impair any such right, remedy or power or be construed to be a waiver of
any default on the part of Lessee or to be an acquiescence therein. No express
or implied waiver by Lessor of any Event of Default shall in any way be, or be
construed to be, a waiver of any future or subsequent Event of Default.


     Except to the extent provided for by the express terms of this Lease, each
of Lessor and Indenture Trustee and any Person claiming through either of them,
waives and agrees not to claim any amount under this Section 16 or otherwise
under this Lease in respect of incidental or consequential damages incurred by
it. 
     To the extent permitted by Applicable Laws, Lessee hereby waives any rights
now or hereafter conferred by statute or otherwise that may require Lessor, its
successors or assigns to mitigate its damages in any particular manner or that
may otherwise limit or modify any of the rights or remedies of Lessor under this
Section 16,
 
                                      75

but nothing contained herein shall eliminate Lessor's obligation to mitigate its
damages as may be required by Applicable Law.

     SECTION 17. Right to Perform for Lessee.
                 ---------------------------

          (a) Right to Cure. If Lessee shall fail to make any payment of
              -------------
Rent to be made by it hereunder or shall fail to perform or comply with any of
its other agreements contained herein or in the Hughes Agreements relating to
any of the Transponders, Lessor or Owner Participant may (but shall not have
any duty to do so) itself make such payment or perform or comply with such
agreement; provided that nothing contained in this Section 17(a) shall be deemed
           -------- ----                                                       
to expand in any way the rights of Owner Trustee or Owner Participant under
Section 16.1 of the Indenture. The amount of any such payment and the amount of
the reasonable expenses of Lessor and Owner Participant incurred in connection
with such payment or the performance of or compliance with such agreement, as
the case may be, together with interest thereon at the Overdue Rate, shall be
deemed Supplemental Rent, payable by Lessee upon demand.

          (b) Lessor is Lessee's Agent and Attorney. Without in any way
              -------------------------------------
limiting the obligatiom of the Lessee or Lessor, hereunder, Lessee hereby
irrevocably appoints Lessor as its agent and attorney-in-fact hereunder, with
full power and authority at any time at which Lessee is obligated to deliver any
Transponder to Lessor, to demand and take such Transponder in the name and on
behalf of Lessee from whomsoever shall be at the time in control thereof.

     SECTION 18. Renewal.
                 -------

          (a) Notice of Renewal or Purchase. Except as otherwise specifically
              -----------------------------                                
provided in Section 18(d), not more than 720 nor less than 540 days prior to the
expiration of the Basic Term or the First Renewal Term, as the case may be, but
in no event before Lessee shall have received the Subsequent Appraisal (provided
Lessee ordered it as provided in Section 20(d), below) (the "Preliminary Notice
                                                             ------------------
Expiration Date"), Lessee shall give Lessor notice (the "Preliminary Notice")
- ---------------                                          ------------------ 
of Lessee's irrevocable intention to (i) renew the Lease pursuant to Section
18(b) in respect of any Selected Transponder and/or all but not less than all
Remaining Transponders; (ii) purchase any Selected Transponder and/or all but
not less than all Remaining Transponders pursuant to Section 19(a)(i).

          If, during the Basic Term, Lessee timely provides the Preliminary
Notice, then not later than 270 days prior to the expiration of the Basic Term,
Lessor shall provide Lessee with written notice specifying whether Lessee's
renewal right under Section 18(b) with respect to any such Transponder shall be
for (A) the Single Renewal Term or (B) for two Renewal Terms (i.e., a First
Renewal Term and a Second Renewal Term) (the "Renewal Term Notice"), provided
                                              -------------------   
that if such Renewal Term Notice is not timely given by Lessor, then such notice
shall be deemed to have been given by Lessor and to have specified two Renewal
Terms.

          With respect to any Selected Transponder, Lessee shall, as an
additional condition to giving the Preliminary Notice and concurrently
therewith, deliver to Lessor a certificate from the chief executive, chief
financial or chief operating officer of STLC stating that:

                                       77
<PAGE>
 
          (1) the Transponder as to which such Preliminary Notice has been given
is the subject of a Use Agreement or Existing Agreement which, by its terms, may
be extended by the User or Sublessee beyond the Lease Term (the "Extension
Right"); and

          (2) such right of the User or Sublessee has either been exercised, or
is presently in effect and has not been waived by such User or Sublessee; and

          (3) the Extension Right was not given to such User or Sublessee for
the primary purpose of enabling the Lessee to meet the conditions necessary to
have the Transponder treated as a Selected Transponder.

          If Lessee gives the Preliminary Notice, then (except as provided in
Section 18(d)) not less than (180) days before the expiration of the Basic Term
or the First Renewal Term, as applicable (the "Final Notice Expiration Date"),
                                              ----------------------------
Lessee shall give Lessor notice of its irrevocable election (the "Final Notice")
                                                                  ------------
of one of the following options: (i) to renew this Lease pursuant to Section
18(b) for any Selected Transponder and/or all Remaining Transponders
identified in the Preliminary Notice (A) for a Single Renewal Term, if
applicable, or (B) for the First Renewal Term or Second Renewal Term, as
applicable, or (ii) to purchase any Selected Transponder and/or all Remaining
Transponders identified in the Preliminary Notice pursuant to Section 19(a)(i).

          If Lessee shall fail timely to deliver the Preliminary Notice, then,
except as provided in Section 18(d), Lessee shall be deemed not to have elected
to renew this Lease or purchase any Transponder, and promptly thereafter, but
in any case within 30 days after the Preliminary Notice Expiration Date, shall
provide Lessor with the names, last known business addresses and telephone
numbers of the Persons using any Transponders pursuant to a Use Agreement (not
including any Occasional Use Service

                                       78
<PAGE>
 
Contract) or an Existing Lease. If Lessee shall fail to deliver the Final Notice
as required above after having delivered the Preliminary Notice, Lessee shall be
deemed to have elected to purchase the Transponders identified in such
Preliminary Notice pursuant to Section 19(a)(i) hereof. The notice requirements
of this Section 18(a) shall not apply to Lessee's right to purchase any
Transponders pursuant to Sections 19(a)(ii) and (iii). As used herein,
"Remaining Transponder" shall mean any Transponder, subject to the Lease, which
is not a Selected Transponder.

      (b) Fair Market Value Renewal Option. If Lessee delivers the Final Notice
          --------------------------------
set forth in Section 18(a), above, stating that it will renew the Lease in
respect of the Transponders identified in such Final Notice, and so long as no
Bankruptcy Default or Event of Default has occurred and is continuing at the end
of the Basic Term or, if applicable, the First Renewal Term, then this Lease
shall be renewed with respect to such Transponders at a Base Rent equal to the
Fair Market Rental Value of such Transponders (as determined pursuant to the
most recent Subsequent Appraisal) and payable in accordance with Section 18(c),
below. The Renewal Term shall be for the following period: (i) in the event
Lessor has specified a Single Renewal Term option in the Renewal Term Notice,
then the term shall begin immediately upon the expiration of the Basic Term and,
unless earlier terminated pursuant to the terms of this Agreement, shall end on
the last day of the useful commercial life of the Satellite (as determined
pursuant to the most recent Subsequent Appraisal) or on the date the Satellite
is disposed of pursuant to Section 13 of the Purchase Agreement or (ii) in the
event Lessor has specified two Renewal Terms in the Renewal Term Notice, then
the term shall begin immediately upon expiration of the Basic Term and, unless
earlier terminated pursuant
 
                                      79
<PAGE>
 
to the terms of this Agreement, shall end on the day prior to the last day of
the period of time which is equal to 80% of the remaining useful commercial life
of the Satellite (as determined pursuant to the Subsequent Appraisal) measured
from the commencement of such term (the "First Renewal Term").  If Lessee renews
                                         ------------------
the Lease for a First Renewal Term, and provided no Bankruptcy Default or Event
of Default has occurred and is continuing at the end of the First Renewal Term,
Lessee may renew the Lease (pursuant to the procedure set forth in Section
18(a), above) for a second renewal term, on terms identical to the First Renewal
Term as set forth in the immediately preceding sentence, except only that such
second renewal term shall begin immediately upon the expiration of the First
Renewal Term and, unless earlier terminated pursuant to the terms of this
Agreement, shall end on the last day of the useful commercial life of the
Satellite (as determined pursuant to the most recent Subsequent Appraisal) or on
the date the Satellite is disposed of pursuant to Section 13 of the Purchase
Agreement (the "Second Renewal Term"). At the end of the Basic Term or First
                -------------------
Renewal Term, as applicable, if Lessee has timely elected to renew this Lease
with respect to any Transponder, then the terms and conditions of this Lease
with respect to such Transponder shall continue in full force and effect during
the following Renewal Term, except that (x) Lessee shall pay Lessor Base Rent
for such Transponder in the amount of the Fair Market Rental Value thereof as
determined by the most recent Subsequent Appraisal and (y) the Stipulated Loss
Values and Termination Values applicable during such Renewal Term shall
initially be the Fair Market Sales Value (determined pursuant to such Subsequent
Appraisal) of such Transponder as of the commencement of the Renewal Term and,
on each Casualty Payment Date during the Renewal Term, shall decline on a
straight line basis by an
 
                                      80
<PAGE>
 
amount per Casualty Payment Date obtained by dividing (iii) the difference
between the Fair Market Sales Value of such Transponder as of the beginning of
such Renewal Term and the estimated Fair Market Sales Value of such Transponder
as of the end of such Renewal Term by (iv) the number of months in such Renewal
Term.

     (c) Renewal Rents. At the end of the Basic Term or the First Renewal Term,
         -------------
as the case may be, if Lessee shall have timely elected to renew this Lease as
aforesaid and if no Bankruptcy Default or Event of Default shall then exist and
be continuing, Lessee and Lessor shall execute a Lease Supplement hereto in form
and substance reasonably satisfactory to Lessor and Lessee to evidence such
renewal. Such Lease Supplement shall provide for the semi-annual (or shorter
period if necessary in case of the last Lease Period) payment of Base Rent for
the Renewal Term, with a final installment on the last day of any such Renewal
Term, payable in each case in arrears, in accordance with the aforesaid
determinations of Base Rent and shall provide for Stipulated Loss and
Termination Values for the Transponders covered thereby with respect to such
Renewal Term determined as aforesaid. The installments of Base Rent during the
Renewal Term shall be equal in amount (except for the last such installment
which shall be pro rated, if necessary, for a Lease Period which is shorter than
six months). All other terms of this Lease, the Guarantee Agreement and the
Participation Agreement, as applicable, shall continue in effect during each
such Renewal Term in accordance with the provisions hereof and thereof, except
as otherwise expressly provided in the Lease. 


     (d) Extended Notice. If with respect to any Transponder subject to an

<PAGE>
 
timely provided the Preliminary Notice, and if following the Preliminary Notice
Expiration Date but on or prior to the end of the Lease Term, the sublessee or
User under such Existing Lease or Use Agreement exercises its renewal rights
thereunder, then Lessee shall be entitled to give the Final Notice with respect
to such Subleased Transponder, such notice to be provided on or before the end
of the Lease Term; provided, however, that Lessee shall not be entitled to
                   --------  -------                                    
exercise the foregoing rights with respect to such Subleased Transponder if
during the period from the Preliminary Notice Expiration Date and prior to
Lessee's delivery of the Final Notice, Lessor has executed a valid and binding
agreement for the purchase, lease or use of such Subleased Transponder with a
third party that is not an Affiliate. During the period between the Preliminary

provide Lessee with written notice of the consummation of any such agreement
with respect to any Subleased Transponder as to which Lessee has not timely
provided the Preliminary Notice.

     SECTION 19. Purchase Options.
                 ----------------

         (a) Purchase Option Events. So long as no Bankruptcy Default or any
             ----------------------
Event of Default has occurred and is continuing, Lessee shall have the right to
purchase:

          (i) if Lessee timely delivers or is deemed to have delivered the Final
Notice contemplated by Section 18(a)(ii) or 18(d) (stating that it will purchase
the Transponders identified in such Final Notice), such Transponders on the
expiration date of the Lease Term or the First Renewal Term, as applicable, at a
purchase price equal to the Fair Market Sales Value of such Transponders as of
such date as determined pursuant to the most recent Subsequent Appraisal;

                                       82
<PAGE>
 
          (ii) all (but not less than all) of the Transponders (A) on the First
EBO Date at a purchase price equal to the First EBO Amount therefor or (B) on
the Second EBO Date at a purchase price equal to the greater of (x) the Second
EBO Amount therefor and (y) the Fair Market Sales Value of such Transponders
as of such date as determined by an appraisal obtained in accordance with
Section 19(b)(i); and

          (iii) if Owner Participant has become a Competitor and fails to
transfer all of its right, title and interest in and to the Lessor's Estate and
the Operative Documents in accordance with Article XIII of the Participation
Agreement within three (3) months after the Owner Participant has become a
Competitor, all (but not less than all) of the Transponders on any Rent Payment
Date, at a purchase price equal to the greater of (A) the Termination Value for
such Transponders as of such Rent Payment Date and (B) the Fair Market Sales
Value of such Transponders as of such Rent Payment Date.

          (b) Notice of Election; Manner of Purchase; Transfer After Purchase.
              ----------------------------------------------------------------

              (i) In order to exercise its right to purchase the Transponders
pursuant to Section 19(a)(ii)(A), Lessee shall, at least ninety (90) days prior
to the First EBO Date referred to in Section 19(a)(ii)(A), give irrevocable
notice to Lessor in writing stating that Lessee will purchase such Transponder
pursuant to Section 19(a)(ii)(A). In order to exercise its right to exercise its
right to purchase all of the Transponders pursuant to Section 19(a)(ii)(B),
Lessee shall give tentative notice to Lessor in writing at least 145 days prior
to the Second EBO Date that it desires to obtain an appraisal of the Fair Market
Sales Value of the Transponders as of the Second EBO Date. Such Fair Market
Sales Value shall be determined pursuant to the Appraisal Procedure (provided

                                       83
<PAGE>
 
that the timetable for the Appraisal Procedure shall be appropriately
accelerated to meet the deadlines set forth in this paragraph 19(b)(i), so long
as notwithstanding such acceleration, the appraiser shall have adequate time to
make a considered determination). Lessee shall give irrevocable notice to Lessor
on the later to occur of (1) five (5) days after completion of the Appraisal
Procedure or (2) ninety (90) days prior to the Second EBO Date (but in no event
later than sixty (60) days prior to the Second EBO Date), if it desires to
consummate the purchase of the Transponders pursuant to Section 19(a)(ii)(B).


     (ii) In order to exercise its right to purchase all of the Transponders
pursuant to Section 19(a)(iii), Lessee shall give tentative notice to Lessor in
writing within 90 days after (A) Owner Participant shall have confirmed to
Lessee pursuant to Section 5.02(i) of the Participation Agreement that it is a
Competitor, or (B) Lessee shall have notified Owner Participant that Owner
Participant has become a Competitor, and Owner Participant shall have become a
Competitor, whichever of (A) or (B) shall first occur, that it desires to obtain
an appraisal of the Fair Market Sales Value of the Transponders as of the Rent
Payment Date specified in the notice given by Lessee under this Section
19(b)(ii). Promptly after Lessee shall have given such notice, such Fair Market
Sales Value shall be determined pursuant to the Appraisal Procedure (provided
that the timetable for the Appraisal Procedure shall be appropriately
accelerated to meet the deadlines set forth in the next sentence, so long as
notwithstanding such acceleration, the appraiser shall have adequate time to
make a considered determination). Lessee shall give irrevocable notice to Lessor
not later than ten Business Days after the completion of the Appraisal Procedure
if it desires to
 
                                      84
<PAGE>
 
consummate the purchase of the Transponders pursuant to Section 19(a)(iii) but
in no event later than fifteen (15) days prior to the Rent Payment Date
specified in the notice referred to in this Section 19(b)(ii), which Rent
Payment Date shall be the next succeeding Rent Payment Date no earlier than 30
days following the date of such notice.

      (iii) On the date of purchase, Lessee shall pay the purchase price for
such Transponders, together with (A) all Interim Rent and Base Rent due and
unpaid prior to the date of such purchase and (B)(i) at any time during the
Basic Term, in the event that the date of purchase is a Rent Payment Date on
which a Scheduled Rent payment designated as an "arrears rent" on Schedule A
hereto as adjusted pursuant to Section 4 is due, any Scheduled Rent designated
as an "arrears rent" on Schedule A as adjusted pursuant to Section 4 due on such
date of purchase with respect to such Transponders and the Rent Differential
Amount, if any, or (ii) at any time during a Renewal Term, any Base Rent due on
such date and (C) any other Rent (including Premium, if any, on the outstanding
Notes) due and unpaid as of the date of such purchase. Upon receipt of the
payments set forth in the preceding sentence, Lessor shall transfer all right,
title and interest of Lessor in and to the Transponders, as is and where is, to
Lessee, free and clear of Lessor Liens and Owner Participant Liens, but
otherwise without warranty, and Lessor shall execute and deliver to Lessee, at
Lessee's reasonable expense, a bill of sale or assignment and such other
instruments, documents and opinions as Lessee may reasonably request to evidence
the valid consummation of such Transfer and shall take such actions under
Section 10 of the Indenture as Lessee may reasonably request.
 
                                      85
<PAGE>
 
      (c) Assumption of Notes. Notwithstanding the provisions of Sections 19(a)
          -------------------
and (b) and subject to compliance with Section 2.13 of the Indenture, if in
connection with a purchase by Lessee of the Transponders pursuant to Section
19(a)(ii) or Section 19(a)(iii) as the case may be, Lessee shall assume the
Notes pursuant to Section 5.05(a) or Article XI of the Participation Agreement,
the obligation of Lessee to pay the purchase price pursuant to Section 19(a)(ii)
or 19(a)(iii), as the case may be, shall be satisfied by such assumption of the
Notes to the extent of the principal amount of the Notes so assumed (after, in
the event that the date of purchase is a Rent Payment Date on which a Scheduled
Rent payment designated as an "arrears rent" on Schedule A hereto as adjusted
pursuant to Section 4 is due, payment of the sum of any Scheduled Rent
designated as an "arrears rent" on Schedule A as adjusted pursuant to Section 4
on the Rent Payment Date on which such purchase is consummated with respect to
such Transponders and the Rent Differential Amount, if any). 

      (d) No Duplication of Rent Differential Amount. In the event that a
          ------------------------------------------
portion of the Scheduled Rent due on any date of purchase is designated as an
"arrears rent" on Schedule A and there is also a payment of Scheduled Rent due
on such date of purchase that is not so designated, a portion of the Rent
Differential Amount with respect to such date of purchase shall be added to the
Scheduled Rent designated as an "arrears rent" due on such date and the
remainder of such Rent Differential Amount shall be taken into account in the
computation of the EBO Amount pursuant to the definition of First EBO Amount or
Second EBO Amount or the computation of Termination Value, as appropriate. It is
intended that the entire amount of the Rent Differential Amount due on such date
of purchase shall be allocated between the
 
                                      86
 
<PAGE>
 
Scheduled Rent designated as an "arrears rent" due on such date and the
computation of the applicable EBO Amount or the Termination Value, as
appropriate and without duplication, in such manner as will preserve the Owner
Participant's Net Economic Return and comply with the minimum payment
requirement (it being understood that the entire amount of such Rent
Differential Amount shall be taken into consideration in making such
allocation).

  SECTION 20. Further Assurances; Default Notice; Subsequent Purchase Option.
              --------------------------------------------------------------

          (a) Further Assurances. Lessee, at its reasonable expense, shall
              ------------------                                        
promptly and duly execute and deliver to Lessor, Owner Participant and Indenture
Trustee such documents and assurances and take such further action as Lessor
(and Indenture Trustee) may from time to time reasonably request in order to
carry out more effectively the intent and purpose of this Lease, the other
Operative Documents and the Hughes Agreements and to establish and protect the
rights and remedies created or intended to be created in favor of Lessor
hereunder and thereunder, to establish, perfect (to the extent practicable, in
the case of the Transponders), and maintain Lessor's right, title and interest
in and to the Transponders and the Indenture Estate and, for the benefit of
Indenture Trustee, the lien and security interest in the Indenture Estate
provided for in the Indenture, subject to no Lien other than Permitted Liens,
including, without limitation, if requested by Lessor, Owner Participant or
Indenture Trustee, at the expense of Lessee, the recording or filing of
appropriate memoranda hereof, or of such financing statements or other documents
with respect hereto as any of Lessor, Owner Participant or Indenture Trustee may
from time to time reasonably request, and Lessor agrees promptly to execute and
deliver such of the foregoing financing statements or

                                       87
<PAGE>
 
other documents as may require execution bv Lessor and to the extent permitted
by Applicable Laws, Lessee hereby authorizes any such financing statements to be
filed without the necessity of signature by Lessee; provided, however, no
                                                    --------  -------  
counterparts hereof shall be filed, unless Lessor or Indenture Trustee shall
determine that it is advisable, in the reasonable opinion of the counsel of
Lessor or Indenture Trustee, as the case may be, to file such counterpart in
order to protect its interest under this Lease; then, upon 30 days' prior notice
and delivery to Lessee of such opinion of counsel of Lessor or Indenture
Trustee, as the case may be, Lessor or Indenture Trustee, as the case may be,
may file such counterpart.

          (b) Notice of Default. Promptly after obtaining Actual Knowledge of
              -----------------                                            
the occurrence or existence of any Default or Event of Default, Lessee shall so
notify Lessor (and Indenture Trustee) and set forth in reasonable detail the
circumstances surrounding such Default or Event of Default and shall specify
what actions Lessee has taken or intends to take to cure such Default or Event
of Default.

          (c)  Subsequent Purchase Option.
               --------------------------

               (i) Right to Purchase Option. So long as, but only so long as, no
                   ------------------------                                   

Bankruptcy Default or any Event of Default shall have occurred and is
continuing, on the expiration of the Lease Term, Lessee shall have the right to
purchase an option (the "Subsequent Purchase Option") at a purchase price (the
                         --------------------------  
"Option Price") determined as set forth below, on the terms and conditions set
 ------------     
forth in Section 20(c)(ii). The Subsequent Purchase Option shall give Lessee the
right, at any time after the expiration of the Lease Term, upon exercise by
Lessee of the option (the "Subsequent Option Exercise Notice"), to purchase and
                           ---------------------------------
to exercise immediate Control over, pending
                                       
                                      88
<PAGE>
 
completion of purchase, all (but not less than all) of the Transponders which
are then owned by Lessor, if Lessee determines, in its sole discretion, that
such purchase will enable Lessee to fulfill its then existing commitments to
transponder purchasers, transponder lessees or other users of transponder
capacity on Hughes satellites. Lessee shall also have the right, pursuant to the
Subsequent Purchase Option, which Lessee may, subject to obtaining any required
FCC approvals, exercise at any time concurrently with or after giving the
Subsequent Option Exercise Notice, to move the Satellite without restriction by
Lessor or any other Person.

      (ii) Creation of Subsequent Purchase Option. In order to be able to
           --------------------------------------
purchase the Subsequent Purchase Option, Lessee shall give the Lessor
irrevocable notice, not earlier than 720 days nor later than 540 days prior to
the expiration of the Basic Term or expiration of the First Renewal Term, as
applicable, but in no event before the Lessee shall have received the Subsequent
Appraisal (provided it shall have been ordered pursuant to Section 20(d) (the
"Subsequent Purchase Option Cut-off Date")), that it shall purchase the
Subsequent Purchase Option unless it purchases the related Transponder or renews
the Lease with respect thereto. The Subsequent Appraisal shall be ordered by
Lessee to determine the Pre-emptibility Cost. Failure timely to give such notice
shall constitute an irrevocable waiver of the rights of Lessee under this
Section 20(c).  As used herein, "Pre-emptibility Cost" shall mean the diminution
in the Fair Market Sales Value, as of the end of the Basic Term or the First
Renewal Term, as applicable, that would be caused to the Transponders as a
result of the issuance to Lessee of the Subsequent Purchase Option, which option
will make the Transponders pre-emptible during the period such Subsequent
Purchase Option is in

                                      89
<PAGE>
 
effect. The Option Price per Transponder shall be equal to the higher of the
Pre-emptibility Cost and seven percent of Buyer's Cost for such Transponder.
Lessee shall pay the Option Price to Lessor, by wire transfer of immediately
available funds upon expiration of the Basic Term or the First Renewal Term, as
applicable, and such Option Price shall be payable for any Transponder Lessee
has not previously purchased from Lessor as of the expiration of the Lease Term.

          (iii) The Subsequent Purchase Price. The Subsequent Purchase Option
                -----------------------------                              
shall give Lessee the right to purchase the Transponders, at any time, with
respect to all (but not less than all) of the Transponders then owned by Lessor
for a price equal to the then Fair Market Sales Value of the Transponders at the
orbital slot at which the Satellite is then located prior to any move of the
Satellite referred to in Section 20(c)(i), and based on the assumption that each
of Seller or Contractor (or Substitute Service Provider, if applicable) is in
compliance with its obligations under the Hughes Agreements (or the Substitute
Service Agreement, if applicable) and taking into account the pre-emptible
nature of such Transponders.

               (iv) Option Excerise. The Subsequent Purchase Option shall be
                    ---------------
exercised by giving the Subsequent Option Exercise Notice. The Subsequent Option
Exercise Notice may be given by facsimile or by personal delivery of written
notice, and in each such case it shall be effective immediately upon receipt.
Notice may also be given by any other means provided for in Section 23 hereof or
in Section 15.03 of the Participation Agreement.

          (v) Survival; Provisions In Other Contracts. Lessor agrees that its
              ---------------------------------------                      
obligations under this Section 20(c) shall, as to each Transponder, survive the

                                       90
<PAGE>
 
termination of this Lease. Lessor agrees that it will, as part of any Transfer
of its rights to any Transponder, including, without limitation, a Transfer to
the Owner Participant, notify its Transferee of the provisions of this Section
20(c) and obtain a written acknowledgment and agreement from such Transferee (in
the form attached as Exhibit D) to immediately relinquish its use of any such
Transponder upon Lessee's exercise of its Subsequent Purchase Option as set
forth in this Section 20(c).

       (d) Subsequent Appraisal. No earlier than 760 days and no later than 720
           --------------------
days prior to the end of the Basic Term, as applicable, Lessee shall have the
option to initiate the Appraisal Procedure, and at Lessee's cost and expense, to
perform an appraisal of the Transponders to determine, as appropriate, the
remaining useful commercial life, residual value and the Pre-emptibility Cost,
and the Fair Market Sales Value and Fair Market Rental Value of the Transponders
as of the end of such Basic Term or the First Renewal Term, as applicable (the
"Subsequent Appraisal"). 
 --------------------

      SECTION 21. Indenture Estate as Security for Lessor's Obligations to
                  --------------------------------------------------------
Indenture Trustee. 
- -----------------

      (a) In order to secure the indebtedness evidenced by the Notes and all
obligations secured by the Indenture, Lessor provides in the Indenture, among
other things, for the assignment (to the extent provided therein) by Lessor to
Indenture Trustee of all of Lessor's right, title and interest to this Lease and
for the creation of a Lien and security interest in favor of Indenture Trustee
for the benefit of the Noteholder in and to the Indenture Estate as described in
the granting clauses of the Indenture. Lessee hereby (a) consents to such
assignment pursuant to the terms of the Indenture, and (b) agrees to pay
directly to Indenture Trustee for so long as the Lien of the

                                      91
<PAGE>
 
Indenture shall remain in effect and thereafter to Lessor, all amounts (other
than Excepted Payments) due and to become due to or for the account of Lessor
and payable by Lessee hereunder or under any other Operative Document or Hughes
Agreement to which Lessee in any capacity is a party which have been assigned or
required to be assigned to Indenture Trustee pursuant to the Indenture or this
Agreement. Lessee acknowledges that, so long as any Notes are outstanding, all
rights of Lessor under this Lease shall be exercised only by the Indenture
Trustee, as assignee of Lessor's rights under this Lease pursuant to the
Indenture, subject, however, to Sections 9.2, 13.1 and 16.4 of the Indenture
and subject to Lessor's rights in respect of Expected Payments.

          (b) Notwithstanding anything to the contrary hereinabove, Indenture
Trustee shall not have any greater rights under the Hughes Agreements than
Lessor shall have pursuant to Section 5(b)(ii) and (iii) of this Agreement or
than the Lessor otherwise has under this Lease.

     SECTION 22. Counterparts; Uniform Commercial Code.
                 -------------------------------------

          This Lease and each Lease Supplement may be executed by the parties
hereto in separate counterparts, each of which when so executed and delivered
shall be an original, but all such counterparts shall together constitute but
one and the same instrument. To the extent, if any, that this Lease constitutes
chattel paper (as such term is defined in the Uniform Commercial Code as in
effect in any applicable jurisdiction), no security interest in this Lease may
be created through the transfer or possession of any counterpart hereof other
than the original executed counterpart which shall be identified as the
counterpart containing the receipt therefor executed by Indenture Trustee on the
signature page thereof.

     SECTION 23. Notices.

          Unless otherwise specifically provided herein, any notice, request or
other communication hereunder shall be in writing and shall be deemed duly given
or made when sent in accordance with Section 15.03 of the Participation
Agreement.

     SECTION 24. Miscellaneous.
                 -------------

          (a) Severability. Any provision of this Lease which is prohibited or
              ------------                                                  
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof or of any provision in any other Operative Document
or Hughes Agreement, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. The provisions of this Lease shall remain valid and
enforceable notwithstanding the invalidity, unenforceability, impossibility or
illegality of performance of any other Operative Document.

          (b) Amendment. Neither this Lease nor any of the terms hereof may be
              ---------                                                     
terminated, amended, supplemented, waived or modified orally, but only by an
instrument in writing signed by the party against which the enforcement of the
termination, amendment, supplement, waiver or modification is sought and, unless
and until Lessee and Lessor shall have received written notice from Indenture
Trustee that the Lien of the Indenture on the Indenture Estate has been released
by Indenture Trustee, no amendment, supplement or waiver by Lessor or Lessee
shall be effective without the written consent of Indenture Trustee, except as
expressly provided in the Indenture.

during the Lease Term and GMHE will have no right to exclude STLC from use or
occupancy of the Transponders during the Lease Term. STLC and GMHE are jointly

shall constitute notice to or from, or election or waiver by, GMHE for all

pursuant to its obligations hereunder may, in certain instances, be taken by the

     (taking into account a reasonable estimate of the effect of inflation and
     deflation). Initial Note Purchaser shall have received evidence
     satisfactory to it (in the form of a copy of the relevant sections of the
     opinion referred to in Section 3.02(a)(i)) that Buyer's Cost of each
                            ------------------

          true on and as of the Delivery Date as though made on and as of the
          Delivery Date, except to the extent that such representations and
          warranties relate solely to an earlier date (in which case such
          representations and warranties shall have been true and accurate on
          and as of such earlier date); (B) no event or condition has occurred
          and is continuing, or would result from the consummation of any

          Section 4.01.  Representations and Warranties of Lessees.  Each Lessee
                         -----------------------------------------              
represents and warrants to each of the other parties hereto that:

          (a) It is a corporation duly organized, validly existing and in good
     standing under the laws of the state of its incorporation, and has all
     requisite corporate power and authority to operate and own or hold under
     lease the properties it purports to operate and own or hold under lease, to
     transact the business it transacts and to otherwise enter into and perform
     its obligations under each Operative Document to which it is or will be a
     party.  Such Lessee is duly qualified to do business as a foreign
     corporation and in good standing in each jurisdiction wherein the failure
     to do so would have a material adverse effect, in the case of STLC, on the
     conduct of its business and operations as presently conducted or on the
     ability of STLC to perform its obligations under the Operative Documents
     and Hughes Agreements to which it is a party and, in the case of GMHE, on
     the financial condition or operations of GMHE and its subsidiaries taken as
     a whole or on the ability of GMHE to perform its obligations under the
     Operative Documents and Hughes Agreements to which it is a party.

          (b) Each Operative Document and Hughes Agreement to which such Lessee
     is or will be a party has been duly authorized by all necessary corporate
     action on the part of, and has been or on or prior to the Delivery Date
     will be duly executed and delivered by, such Lessee and neither the
     execution and delivery thereof, nor the consummation by it of the
     transactions contemplated thereby (including, without limitation,

                                      18
<PAGE>
 
     the operation of the Transponders), nor compliance by such Lessee with any
     of the terms and provisions thereof (i) requires any approval of
     stockholders or approval or consent of any trustee or holders of any of its
     indebtedness or obligations; (ii) contravenes any law, judgment,
     governmental rule or regulation or order applicable to or binding on it or
     any of its properties, the contravention of which would have a material
     adverse effect on the conduct of its business and operations as presently
     conducted or the performance of its obligations under the Operative
     Documents and the Hughes Agreements to which it is a party; (iii)
     contravenes or results in any breach of, or constitutes any default under,
     any indenture, mortgage, chattel mortgage, deed of trust, conditional sales
     contract, bank loan or credit agreement for borrowed money, contract or
     other agreement or instrument to which it is a party or by which it or any
     of its properties may be bound or affected, the contravention, breach or
     default of which would have a material adverse effect on the conduct of its
     business and operations as presently conducted or the performance of its
     obligations under the Operative Documents and the Hughes Agreements to
     which it is a party; (iv) contravenes its corporate charter or by-laws; or
     (v) results in the creation of any Lien (other than Permitted Liens
     described in clauses (a) and (b) of the definition thereof) upon the
     Transponders or any material property of such Lessee.

          (c) Neither the execution and delivery by it of the Operative
     Documents or Hughes Agreements to which it is or will be a party, nor the
     consummation by it of any of the transactions (including, without
     limitation, the operation of the Transponders) contemplated thereby,
     requires the consent, approval or authorization of, the giving of notice
     to, or the registration with, the recording or filing of any document with,
     or the taking of any other action in respect of, any Governmental Body,
     except (i) such of the foregoing as have been obtained, given or done, (ii)
     the filings and actions described in clause (ii) of Section 4.01(g), and
                                                         ---------------
     (iii) such routine notification from Seller to the FCC as may be required
     after the Delivery Date under the laws in existence on the Delivery Date.
     As of the Delivery Date, any and all notifications that may be required to
     be given by Seller to the FCC pursuant to the foregoing clause (iii) are
     routine in nature and

                                      19

     for informational purposes only, and no such notice as of the Delivery Date
     requires any official action or determination by the FCC as of the Delivery
     Date, is subject to approval or disapproval by the FCC or as of the
     Delivery Date gives rise to a right by any third party to file a petition
     to deny.

          (d) Each Operative Document and Hughes Agreement to which such Lessee
     is a party constitutes the legal, valid and binding obligation of such
     Lessee, enforceable against such Lessee in accordance with its terms,
     except as such enforcement may be subject to bankruptcy, insolvency,
     moratorium or other similar laws affecting creditors' rights generally and
     to general principles of equity.

          (e) Except as disclosed in writing to Indenture Trustee, Owner
     Trustee, Owner Participant and Initial Note Purchaser prior to the
     execution of this Agreement, there are no actions, suits or proceedings
     pending against such Lessee in any court or before any arbitrator of any
     kind or before or by any Governmental Body, or to the knowledge of such
     Lessee threatened, which question the legality or validity of any of the
     Operative Documents or Hughes Agreements to which such Lessee is a party or
     the transactions contemplated thereby or which, individually or in the
     aggregate, if adversely determined, would have a material adverse effect in
     the case of STLC, on the conduct of its business and operations as
     presently conducted or on the ability of STLC to perform its obligations
     under the Operative Documents or the Hughes Agreements to which it is a
     party and, in the case of GMHE, on the financial condition or operations of
     GMHE and its subsidiaries taken as a whole or on the ability of GMHE to
     perform its obligations under the Operative Documents and Hughes Agreements
     to which it is a party.

          (f) Such Lessee is not in violation of any Order of any Governmental
     Body, which violation would have a material adverse effect on the conduct
     of its business and operations as conducted on the date hereof.

          (g) On the Delivery Date, upon delivery of the Bill of Sale to Owner
     Trustee and payment of Buyer's Cost for the Transponders by Owner Trustee

     all Liens other than Permitted Liens described in clauses (a) and (b) of
     the definition thereof and (ii) except for the filing of a Uniform
     Commercial Code financing statement or statements covering the Indenture
     Estate and naming Owner Trustee as debtor and Indenture Trustee as secured
     party (which have been filed or received or delivered to counsel for
     Indenture Trustee for filing or recording), and except for the taking by
     Indenture Trustee of possession of the executed original counterpart of the
     Lease, no further action, including any filing or recording of any
     document, is necessary or advisable in order to establish, confirm and
     protect Owner Trustee's right, title and interest in and to the
     Transponders or to perfect for the benefit of the Noteholders the security
     interest in the Indenture Estate provided for in the Indenture (other than

     and the Operative Documents, the purchase by the Initial Note Purchaser of
     the Notes, and the acquisition by Owner Participant of its beneficial
     interest in the Lessor's Estate will involve any prohibited transaction

     unrelated to its relationship with Owner Participant, the expenses incurred
     in connection with the appointment of a successor Owner Trustee as a result
     thereof shall be paid by Lessee. Otherwise, in connection with Owner
     Participant's appointment of a successor Owner Trustee, the expenses
     incurred in connection therewith and any incremental increase in fees

     Information necessary to protect Lessees from any adverse competitive
     impact that could arise from disclosure of such information. Owner
     Participant acknowledges that Lessees will suffer irreparable harm in the

     any such action, any Indemnitee shall have the right to employ separate
     counsel in such action and participate therein, subject to the preceding
     sentence, but the fees and expenses of such counsel shall be at the expense

     the risk of criminal penalties, unless such action does not lead to the
     commencement (including, without limitation, the impanelling of a grand
     jury or similar investigatory proceeding) of a criminal proceeding. Lessees

          (d)  Notwithstanding the provisions of the immediately preceding
     paragraph, the omission by any Indemnitee to notify any Lessee of any
     Expense shall not relieve such Lessee from any liability which it may have
     hereunder in respect of any such Expense or other Expense; provided,

     payments then due and owing to such Indemnitee under the Operative
     Documents), an amount equal to the sum of (I) the actual reduction in
     Taxes realized by such Indemnitee which is attributable to such deduction
     or credit, and (II) the actual reduction in Taxes realized by such
     Indemnitee as a result of any payment made by such Indemnitee pursuant to
     this sentence; provided, however, that such Indemnitee shall not be

     obligated to make any payment to any Lessee pursuant to this sentence if
     and for so long as a Payment Default, Bankruptcy Default or any Event of
     Default sha1l have occurred and be continuing, but shall promptly make such
     payment once all such Events of Default shall no longer be continuing; and
     provided, further, however, that such Indemnitee shall not be obligated to
     --------  -------  -------

     Indemnitee as a result of a disallowance or reduction of any tax benefit
     taken into account in the prior sentence shall be treated as a Tax for
     which Lessees are obligated to indemnify such Indemnitee pursuant to the
     provisions of Article VII hereof without regard to Section 7.02 (other than
                   -----------                          ------------

the extent resulting from the intentional breach by such Indemnitee of any of
its representations, warranties or covenants in any of the Operative Documents

shall pay Lessees when such tax benefit is actually utilized (but not before
Lessees shall have made all payments and indemnification theretofore due to such
Indemnitee pursuant to the Operative Documents) an amount equal to the lesser of

notwithstanding the foregoing portions of this sentence, such Indemnitee shall
not be obligated to make any payment to Lessees pursuant to this sentence if and
for so long as an Event of Default shall have occurred and be continuing, but
shall promptly make such payment once all Events of Default shall no longer be
continuing; it being intended that such Indemnitee should not realize a net tax
benefit pursuant to this Article VII unless Lessees shall first have been made

Any Taxes that are imposed on any Indemnitee as a result of a disallowance or
reduction of any tax benefit taken into account in the prior sentence shall be
treated as a Tax for which Lessees are obligated to indemnify such Indemnitee

Lessees after such Indemnitee acquires Actual Knowledge of such action and in
any event within 30 days after receipt by such Indemnitee of a written claim
(but failure to notify Lessees within such 30-day period shall not impair such
Indemnitee's right to indemnification under this Article VII unless Lessees'

failure) and shall, to the extent permitted by law, not pay the claim before the
earlier of (i) 30 days after giving Lessees notice, and (ii) receipt of Lessees'
response.  If either Lessee shall so request within 30 days after receipt of
such notice, such Indemnitee shall, at Lessees' expense reimbursed to such
Indemnitee on an After-Tax Basis, contest the imposition,

such contest (including the right to forego any and all administrative appeals,
proceedings, hearings and conferences in respect of such claim and the right to
select the forum for such contest and determine whether any such contest shall
be by (i) resisting payment of such Tax, (ii) paying such Tax under protest or
(iii) paying such Tax and seeking a refund thereof) shall remain with such
Indemnitee and its counsel acting in good faith; provided, however, that such

for so long as there shall not have been a Bankruptcy Default nor shall Owner
Participant have exercised any of its remedies pursuant to Section 16 of the
Lease, no such proceedings or litigation shall be settled or otherwise
compromised without the prior written consent of Lessees. If such Indemnitee so
elects, such contest shall be conducted by Lessees in the name of such
Indemnitee (subject to the preceding proviso) and in no event shall such
Indemnitee be required or Lessees be permitted to contest or to continue to
contest, as the case may be, the imposition of any Tax for which Lessees are

all reasonable costs and expenses that such Indemnitee may incur in connection
with contesting such claim (including, without limitation, all costs, expenses,
losses, reasonable legal and accounting fees and disbursements) on an After-Tax
Basis; (B) such Indemnitee shall have determined in good faith that the action
to be taken will not result in any material danger of sale, forfeiture or loss
of any Transponder or any part thereof or any interest therein (except if
Lessees shall have made provision to protect the interests of such Indemnitee in
a manner satisfactory to such Indemnitee); and (C) if such contest shall be
conducted in a manner requiring the payment of the claim, Lessees shall have
advanced on an interest-free basis an amount equal to the amount of such claim
which such Indemnitee shall have elected to pay and Lessees shall have
indemnified the Indemnitee in a manner satisfactory to the Indemnitee, for any
adverse tax consequences from the receipt, or interest-free nature, of such
advance.

to a proposed claim or contest shall not affect the rights and obligations of
such Indemnitee and Lessees hereunder in respect of any other taxable period or
any other taxing authority unless such election not to contest materially
impairs as a legal or practical matter the ability of Lessees or an Indemnitee

the manner and at the rate or rates used to compute interest on refunds or
overpayments to the relevant taxing authority, plus any net tax benefit realized
by such Indemnitee as a result of the repayment of such advance with such
interest; such repayment shall be made upon the occurrence of the earlier of (x)
final adjudication of such contest (including a settlement thereof) and

provided; provided, however, notwithstanding the foregoing, such Indemnitee

Trustee or, where not so permitted, promptly notify Owner Participant of such
requirement and prepare and deliver such report, return or statement to Owner
Participant in a manner satisfactory to Owner Participant within a reasonable
time prior to the time such report, return or statement is to be filed.

request such data as any Indemnitee may require to enable such Indemnitee to

                          --------------------------------------------       
Lessee and each of Owner Participant, Initial Note Purchaser, Owner Trustee and
Indenture Trustee agrees to effectuate the resale of the Notes in a transaction
in accordance with Rule 144A under the Securities Act ("Rule 144A") and the
reset of the interest rate on the Notes in connection with such resale, as soon
as commercially feasible after the Delivery Date on the terms and subject to the
conditions set forth herein and in Annex A attached hereto, which is hereby
incorporated by reference and shall be binding upon the parties as if fully set
forth herein, and, to the extent reasonably within its control, to cause the
conditions to such reset and resale herein (including Annex A) to be met.  In
connection with such transaction, Initial Note Purchaser shall propose a
Remarketing Date, and Lessees shall use commercially reasonable efforts to
provide the Preliminary Offering Memorandum to Initial Note Purchaser on such
date.  After the Remarketing Date, Initial Note Purchaser and Lessees, acting on
behalf of Owner Trustee, shall designate a mutually acceptable Repricing Date
and Reset Rate, which rate, in their respective best judgments, will be
sufficient to allow

<PAGE>
 
Initial Note Purchaser to resell the Notes at 100% of the principal amount
thereof in a transaction in accordance with Rule 144A.

          On or prior to the Repricing Date, Initial Note Purchaser and Lessees,
acting on behalf of Owner Trustee, shall determine the Reset Date, which date
may be postponed by mutual agreement of Lessees and Initial Note Purchaser.
Initial Note Purchaser and Lessees shall notify Owner Trustee and Owner
Participant of such Reset Rate and Reset Date and any postponements thereof. On

Trustee of the Reset Rate and the Reset Date.

          On or prior to the Reset Date, Lessees and Owner Trustee shall execute
and deliver a supplement to the Lease reflecting the adjustments described in
the preceding paragraph, and Owner Trustee and Indenture Trustee shall execute
and deliver a supplement to the Indenture reflecting such adjustments and

          If Initial Note Purchaser and Lessees, acting on behalf of Owner
Trustee, fail to set a Repricing Date within 10 Business Days after an initial
Remarketing Date, then Initial Note Purchaser and Lessees, acting on behalf of
Owner Trustee, may set one or more other Remarketing Dates in the manner
described in the first paragraph of this Section 10.01 until the earlier to

to the 120th day following the Delivery Date, on any date thereafter Initial
Note Purchaser may in its sole discretion resell some or all of the Notes in one
or more Unilateral Resales that are exempt from the registration requirements of

interest rate on the Notes. In connection with the first such Unilateral Resale,
each of the parties to this Participation Agreement agrees to effectuate the
reset of the interest rate upon such Unilateral Resale on the terms and subject

Upon such Remarketing Date, Lessees shall provide the Preliminary Offering
Memorandum to the Initial Note Purchaser. After the Remarketing Date, Initial
Note Purchaser may designate a Repricing Date upon three Business Days' notice

Day prior to such Repricing Date, Initial Note Purchaser shall notify Lessees,
Owner Participant, Owner Trustee and Indenture Trustee of the Reset Date and

accordance with its terms except as the same may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
rights of creditors generally and by general principles of equity, and except as
limited by applicable laws that may affect the remedies provided for in the
Lease, which laws, however, do not in the opinion of such counsel make the
remedies provided for in the Lease inadequate for the practical realization of
the rights and benefits provided for in the Lease. In the event such Lessee is
unable to provide such opinion, concurrently with the purchase of the Beneficial
Interest Lessees shall assume (on a full recourse basis) the obligations of
Owner Trustee under the Notes and under the Indenture in accordance with,
subject to the conditions of and with the effect provided in Section 5.05(a)

which by its terms is payable in arrears accrued to and including, or
attributable to events or circumstances occurring prior to, the date of purchase
pursuant to this Section 11.02.  Owner Trustee hereby agrees that upon receipt

amounts to the Transferor.

purposes of the Operative Documents and each reference herein to Owner
Participant shall thereafter be deemed a reference to such Lessee for all

          Section 14.04.  Obligation to Purchase for Removal.
                          ----------------------------------

          (a)  If, at any time following the expiration or earlier termination
     of the Lease and prior to the end of the useful commercial life of the
     Satellite, STLC elects to exercise its right with respect to a Removal of
     the Satellite pursuant to clause (i) of the first sentence of Article 14 of
     the Purchase Agreement (a "Voluntary Removal"), then within 5 days of
     receipt of the appraisal required hereunder, Lessees shall purchase, and
     pay to Lessor in immediately available funds the Removal Purchase Price of
     all, but not less than all, Transponders then owned by Lessor or Owner
     Participant, regardless of whether any such Transponder, at the time of the
     Voluntary Removal, failed to comply with the Transponder Performance
     Specifications or otherwise was a Failed Transponder. STLC shall not be
     required to wait until the appraisal has been completed and payment made to
     do the Removal; provided it shall pay interest on the Removal Purchase
                     --------
     Price at the Prime Rate from the date of removal to, but excluding, the
     date of payment. In all cases of a Removal other than a Voluntary Removal,
     including a Removal pursuant to clause (ii) of the first sentence of
     Article 14 of the Purchase Agreement or where Seller is required to
     undertake such a Removal after the expiration of the Lease Term due to
     actions by the FCC or other Governmental Authority not

                                      78
<PAGE>
 
     sought by Lessees (collectively referred to as "Involuntary Removals"),
     Lessees shall have no payment or other obligation to Lessors or Owner
     Participant as a result of such removal.

          (b)  The Removal Purchase Price for each such Transponder purchased
     hereunder shall be the Fair Market Sales Value thereof, if any, as
     determined in accordance with the Appraisal Procedure, which shall be
     commenced as soon as is practicable after STLC determines to make the
     Voluntary Removal. Any such determination of Fair Market Sales Value of any
     removed Transponder shall be made on the assumption that, but for such
     Voluntary Removal, such Transponder would not have been taken out of
     service pursuant to the Purchase Agreement except as, and until, an
     Involuntary Removal occurred or the useful commercial life of the Satellite
     would otherwise have ended had Seller not made the Voluntary Removal. The
     valuation date will be the Removal Date. Upon compliance by STLC with all
     the terms of this Section 14.04, Buyer shall transfer title to such
                       -------------
     Transponders to STLC without any representation, warranty or recourse
     whatsoever except as to the absence of Lessor Liens and Owner Participant
     Liens. After any such purchase, neither STLC nor any Affiliate thereof
     shall use any Transponder for any revenue-producing purpose.

     request of Lessees shall to the extent practicable at the Lessees' sole
     cost and expense and with counsel reasonably satisfactory to Recipient,
     fully cooperate with Lessees, in contesting such disclosure. If after such
     contest disclosure is still required, then Recipient shall seek, if
     practicable, confidential treatment of such information from the applicable

Indenture Trustee by Lessor. Lessor shall give notice to Lessee and Indenture
Trustee at least five Business Days prior to the Interim Rent Payment Date if
funds equal to the Lessor Payment Amount will not be paid by Lessor on such
date; provided, however, that Lessor's failure to deliver such notice shall not

such next succeeding Business Day) no interest shall accrue on the amount of
such payment from and after such scheduled date.

          (e) Late Payment. If any Rent shall not be paid when due, Lessee shall
              ------------

Payment), shall be at least equal to the amount of scheduled principal and
accrued interest due and payable on the Notes outstanding on such day in respect
of such Transponder and (2) for any Transponder, the amount of Stipulated Loss

payable under this Lease on any such date in respect of such Transponder
(excluding, in each case, any portion thereof constituting an Excepted
Payment), shall be at least equal to the amount of principal and accrued
interest and Premium, if any, which would be due and payable on the Notes
outstanding on such date in respect of such Transponder, assuming such date or
such applicable EBO Date, as the case may be, was the date such payment was due
on the Notes in respect of such Transponder in connection with any payment by
Lessee of such Stipulated Loss Value, Termination Value or any EBO Amount.

          (g) Net Lease; No Setoff; Etc. This Lease is a net lease and,

Lease by any trustee or receiver of any Person mentioned above, or by any court;
(8) any claim that STLC or GMHE has or might have against any Person, including,

Participant or any Noteholder to perform or comply with any of the terms hereof
or of any other Operative Document or Hughes Agreement;

change (except as to the subject matter of any such amendment or change), or any
assignment of, any rights under any Operative Document or Hughes Agreement, or
any waiver or other action or inaction under or in respect of any Operative
Document or Hughes Agreement, or any exercise or nonexercise of any right or
remedy under or in respect of any Operative Document or Hughes Agreement,
including, without limitation, any foreclosure or other remedy under the
Indenture or this Lease or the sale, pursuant to any such foreclosure or such
exercise of other remedy, of any Transponder or any portion thereof or interest
therein; or (14) any other occurrence whatsoever, whether similar or dissimilar
to the foregoing, whether or not Lessee shall have notice or knowledge of any of
the foregoing. Except as expressly provided herein, Lessee, to the extent
permitted by law, waives all rights now or hereafter conferred by statute or
otherwise to quit, terminate or surrender this Lease, or to any diminution or
reduction of Rent payable by Lessee hereunder. If this Lease shall be terminated
in whole or in part for any reason whatsoever except as expressly provided
herein, Lessee shall nonetheless pay to Lessor (or, in the case of Supplemental
Rent, to Lessor for its own account or to any Person entitled to such
Supplemental Rent as specified herein or in the appropriate Operative Document
or the Hughes Agreement), an amount equal to each Rent payment at the time and
in the manner that

<PAGE>
 
such payment would have become due and payable under the terms of this Lease if
it had not been terminated in whole or in part. Except with respect to payment
of any Advance Amount pursuant to Section 3(b)(i)(A) and 3(c)(ii), each payment
of Rent shall be final, and the Lessee agrees not to seek to recover all or any
part of any such payment from the Lessor, the Indenture Trustee or the Owner
Participant for any reason under any circumstance whatsoever; provided, however,

that nothing contained in this Section 3(g) shall prevent the Lessee from
bringing an action for damages suffered by the Lessee as a result of the breach
by any Person of any obligation of such Person expressly stated in any Operative
Document or Hughes Agreement or for equitable relief to obtain compliance with
any such obligation, or for the return of mistakenly paid amounts of any Rent.
Nothing contained in this Section 3(g) shall be construed as: (1) a guaranty of
(i) the value of the Transponders upon termination of the Basic Term or any
Renewal Term or (ii) the useful life of the Transponders or (iii) payment of any
of the Notes; or (2) a prohibition of assertion of any claim against any
manufacturer, supplier, dealer, vendor, contractor, subcontractor or installer
with respect to the Transponders; or (3) a waiver by Lessee of its right to
assert and sue upon any claims it may have against any other Person in one or
more separate actions.

          (h) Repayment of Advance Amount. Lessee shall be repaid, in the manner
              ---------------------------
provided in the next sentence, any Advance Amount (plus interest on the
outstanding portion thereof at a simple interest rate of 14% per annum from the
date that any portion of such amount is advanced by Lessee to but not including
the date it is repaid by Lessor) (the "Repayment Amount"). The Lessee shall be
                                       ----------------
entitled to offsets (without duplication) against any payments of Rent (other
than as limited by the three

                                      10

provisos to this sentence) due from Lessee to Lessor or Owner Participant
(including, without limitation, Interim Rent, Base Rent, Stipulated Loss Value,
Termination Value or the applicable EBO Amount and all other amounts payable to
Lessor in connection with any termination of this Lease, but excluding Excepted
Payments payable to the Trust Company) until Lessee has received the Repayment
Amount, whether by cash payment, offsets as herein provided, or any combination
thereof; provided, however, that in case of any payment due to Lessor from
         --------  -------
Lessee, Lessee's right of offset shall be limited to the portion of such
payment, if any, distributable to Lessor or Owner Participant thereunder;
provided further, however, that no such offset or aggregate combined effect of
- -------- -------  -------
separate offsets shall reduce the amount of any installment of Interim Rent,
Base Rent, Supplemental Rent due under Section 3(b)(i)(A) or Section 3(c)(ii)
Stipulated Loss Value, Termination Value or the EBO Amounts as of any date
payable under this Lease to an amount that would be in contravention of the
minimum payment requirements of Section 3(f); and provided further, however,
                                                  -------- -------  -------

              -----------------------------------------------
Loan" is made pursuant to the Tax Indemnification Agreement, such that interest
payments are called for pursuant to such Tax Indemnification Agreement, then
Lessee shall pay Supplemental Rent in the amounts of interest, and on the dates
specified in such Section; provided, however, that notwithstanding any other
                           --------  -------
provisions in this Lease such Supplemental Rent shall not be due if and to the
extent that such interest payments have not been, or are not simultaneously,
made.

              -----------------------------                                     
of this Section 4 and to the provisions of Section 3(f), the amounts of

Owner Participant's Net Economic Return with respect to the Transponders, in the
event that for any reason:

               (i) The Delivery Date for the Transponders is a date other than
     as set forth therefor in Schedule III to the Participation Agreement;

               (ii) The Lessor Interim Amount or the Lessor Payment Amount is
     other than the respective amounts set forth therefor in Schedule III to the
     Participation Agreement, or the actual amortization schedule attached as

                                       12
<PAGE>
 
Schedule X to the Notes on the Delivery Date is other than the Assumed
Amortization Schedule.

               (iii) the Debt Commitments with respect to the Transponders is
     other than as set forth in Schedule III to the Participation Agreement;

               (iv) (A) the amount of Transaction Costs with respect to the
     Transponders paid by Lessor as a percentage of Buyer's Cost of the
     Transponders is other than as set forth as "Estimated Transaction Costs" in
     Schedule III to the Participation Agreement, or (B) the date on which the
     Transaction Costs with respect to the Transponders are actually paid by
     Lessor is other than the Delivery Date for the Transponders or (C)
     [Intentionally Omitted];

               (v) a Covered Tax Law Change with respect to the Transponders
     shall have occurred;

               (vi) Lessee elects (with the consent of the Owner Participant, if
     required) to make an adjustment to Scheduled Rent in accordance with the
     Section of the Tax Indemnification Agreement referred to in Item 5 to
     Schedule E;

               (vii) the Notes are refunded pursuant to Section 12.01 of the
     Participation Agreement (in which case the adjustment shall be made to take
     into account any change in the interest rate on, or the amortization
     schedule of, the applicable series of Refunding Notes from those of the
     Refunded Notes); or

               (viii) the interest rate on the Notes is reset as contemplated by
     Article X of the Participation Agreement.

     In connection with any adjustment to Scheduled Rent made pursuant to this
Section 4, appropriate corresponding adjustments shall be made to Stipulated
Loss Value, Termination Value, each EBO Amount, and the amortization schedule
for the Notes, as permitted by the Indenture, which amortization schedule shall
be satisfactory to Lessee and Lessor. Any adjustment pursuant hereto shall
comply in all respects with the minimum payment requirements of Section 3(f). In
addition, any adjustment pursuant hereto shall be made in the same manner, and
shall employ the same methodology, assumptions (including, without limitation,
each of the pricing assumptions set forth in Schedule III of the Participation
Agreement, as such pricing assumptions shall have been modified by previous
adjustments under this Section 4 or pursuant to the Tax Indemnification
Agreement), except as such assumptions shall have been modified by the event
giving rise to such adjustment, and constraints employed in the original
calculation of Scheduled Rent, Stipulated Loss Value, Termination Value and the
EBO Amounts as of the Delivery Date. In making any adjustment pursuant to
clause (ii) or (viii) above, Interim Rent will be adjusted such that the
difference between (A) the sum of the Lessor Interim Amount and the Lessor
Payment Amount and (B) the Interim Rent does not exceed the amount set forth on
Schedule III to the Participation Agreement as the "Deferred Equity Limit." If
Stipulated Loss Value (or any amount measured thereby), Termination Value or the
applicable EBO Amount shall become due and payable hereunder prior to completion
of an adjustment to Scheduled Rent pursuant to this Section 4, the adjustment
shall be completed prior to the date such payment is due. If required pursuant
to Section 6 of the Tax Indemnification Agreement, Stipulated

                                      14
 
<PAGE>
 
Loss Value, Termination Value and the EBO Amounts shall be appropriately
adjusted in accordance with the applicable provisions of this Section 4.

          It shall be a condition to the application of clause (v) of Section
4(a) that on or prior to the closing on the Delivery Date for the Transponders,
Owner Participant shall have provided Lessee with written notice of any Tax Law
Change or Proposed Tax Law Change with respect to the Transponders, or Lessee
shall have provided Owner Participant with written notice of any Tax Law Change
or Proposed Tax Law Change with respect to the Transponders, as to which Owner
Participant or Lessee, as the case may be, seeks or may seek the application of
this Section 4.

          (b)  Limitations on Adjustments.
               --------------------------

               (1) (A) Any adjustment of Scheduled Rent pursuant to this
Section 4 shall be computed in a manner so as to satisfy the minimum payment
requirements of Section 3(f) of this Lease. In addition, any adjustment of
Scheduled Rent (due with respect to the Basic Term) pursuant to this Section 4
shall be computed in a manner so as to satisfy the requirements of Sections
4.02(5), 4.07(1) and (2) and 4.08 of Revenue Procedure 75-28, 1975-1 C.B. 752,
as in effect on the Delivery Date; provided that the requirements of such
Section 4.08 shall be applied, in the case of any adjustment pursuant to this
Section 4, on a prospective basis taking into consideration only Scheduled Rent
(due with respect to the Basic Term) payable by Lessee from and including the
first Rent Payment Date as of which the adjustment takes effect; provided
                                                                 --------
further that any adjustment of Scheduled Rent (due with respect to the Basic
- -------
Term) shall be governed by the foregoing requirements of Sections 4.07 and/or
4.08 of Revenue Procedure 75-28 only to the extent that Scheduled Rent (due with
respect to the Basic

                                       15
<PAGE>
 
Term) as of the Delivery Date for the Transponders satisfied such requirements
as in effect on the Delivery Date. (B) In the case of any adjustment pursuant to
clauses (i) through (iii) or (vi) of Section 4(a), any such adjustment of
Scheduled Rent (due with respect to the Basic Term) will be structured in such a
fashion so as not to create, solely during the periods from and after the Basic
Term Commencement Date, any risk that Section 467 of the Code will apply to
Owner Participant (determined without regard to any change in law that occurs
after the Delivery Date) greater than is created by the original rent structure
with respect to the Transponders in effect on the Delivery Date for the
Transponders. (C) In the case of any adjustment pursuant to clauses (iv), (v),
(vii) or (viii) of Section 4(a), any such adjustment of Scheduled Rent (due with
respect to the Base Term) shall satisfy (on a prospective basis), Section 467 of
the Code and the Regulations, as in effect at the time of such adjustment;
provided, however, that in the event the Reset Date occurs after the Basic Term
- --------  -------
Commencement Date, any such adjustment of Scheduled Rent (effected in connection
with the reset of the interest rate on the Notes) effective on such Reset Date
shall be made in a fashion to satisfy either the standard set forth in clause
(B) of this Section 4(b)(1) or the standard set forth in clause (C) of this
Section 4(b)(1) (selected by Lessor at such time) for satisfying the constraints
of section 467 of the code.

               (2) [Intentionally Omitted]

               (3) In making any adjustment pursuant to this Section 4, no
adjustment shall be made to reflect the application of Section 168(d)(3) of the
Code.

          (c) Timing of Adjustments. All adjustments to be made pursuant to this
              ---------------------
Section 4 shall be made on and shall be effective as of the Delivery Date for
the

                                       16
<PAGE>
 
Transponders if practicable and to the extent not then practicable, any such
adjustment shall be made as soon as practicable after the event giving rise to
the adjustment and shall in each case be made in respect of installments of
Scheduled Rent becoming due on or after 15 days after the date such adjustment
is made; provided that all adjustments to be made pursuant to clause (i) through
(iii) of Section 4(a)(1) shall be made no later than September 1, 1992;
provided, further, that with respect to an adjustment pursuant to clause (viii)
- --------  -------  ----
of Section 4(a), such adjustment shall made be on or prior to the Repricing
Date.

          (d)  Confirmation of Adjustments.
               ---------------------------

               (1) The amount of any adjustment pursuant to this Section 4
shall be determined by Owner Participant, which shall provide to Lessee, Lessor
and Indenture Trustee notice of such adjustment accompanied by an Officer's
Certificate of Owner Participant, which Officer's Certificate shall set forth
the amount of and the reason for any such adjustment and which shall confirm
that such adjustment was made in accordance with the provisions of this Section
4. Such adjustment shall, subject to the following provisions of this Section
4(d), become effective as of the date therein set forth (determined in
accordance with Section 4(c)) upon delivery by Owner Participant to Lessee of
such notice and Officer's Certificate.

          (2) Within twenty (20) Business Days after receipt of an Officer's
Certificate pursuant to paragraph (d)(1) above, if Lessee believes that such
adjustment is incorrect, Lessee may request that such adjustment be verified by
one of the six largest U.S. independent public accounting firms, including Owner
Participant's regular independent accounting firm, as selected by Owner
Participant. In such verification

                                       17
<PAGE>
 
process, such accounting firm shall be given access by Owner Participant to the
assumptions, methods of calculation, computations, computer programs and files
employed by Owner Participant in calculating such proposed adjustment and
employed in the original calculation of Scheduled Rent, Stipulated Loss Value,
Termination Value and the EBO Amounts as of the Delivery Date, subject to the
execution of such confidentiality agreements as Owner Participant shall
reasonably request. Any revised adjustment resulting from such verification
shall become effective on the next Rent Payment Date occurring on or after 15
days after such verification has been concluded.

          (3) Such verification by such accounting firm shall be at the expense
of Lessee unless such verified adjustment results in a readjustment in favor of
Lessee that exceeds 5 basis points in the Net Present Value of Scheduled Rent,
in which case verification shall be at the expense of Owner Participant. Such
determination of adjustment by Owner Participant, or, if so requested in
accordance with Section 4(d)(2), such verified adjustment, as the case may be,
shall be conclusive and binding on the parties to the Participation Agreement.

      (e) Further Assurances. At the time any adjustment is made pursuant to
          ------------------
this Section 4, the parties hereto shall enter into a supplement to this Lease
to reflect such adjustment and shall enter into such amendments to the other
Operative Documents (including an amendment to Schedule III to the Participation
Agreement) and do such further acts as may be reasonably required in order to
effectuate such adjustment; provided that such adjustment shall become effective
as provided in Section 4(d) without regard to the date on which such supplement
to this Lease is executed and delivered.

OR LIABILITY WITH RESPECT THERETO, except that Lessor hereby represents,
warrants and covenants that on the Delivery Date (A) Lessor shall have whatever
title to such Transponder was conveyed to it by Seller under the Purchase
Agreement and the Bill of Sale thereto and (B) during the Lease Term (so long as
no Event of Default shall have occurred and be continuing) Lessor will not,
through its own actions or inactions, interfere with the quiet enjoyment of any
Transponder by Lessee and agrees that it will not directly or indirectly create,
incur, assume or suffer to exist any Lessor Lien on or with respect to any
Transponder. The provisions of this Section 5(a) have been negotiated, and
except as expressly provided in the Operative Documents, the foregoing
provisions are intended to be a complete exclusion and negation of any
warranties by Lessor, the Trust Company, Owner Participant, any Noteholder or

diminish or otherwise affect any right Lessee may have with respect to any
Transponder against any other third person. Neither Lessor, the Trust
Company, Owner Participant, any Noteholder or Indenture Trustee shall at any
time be required to inspect such Transponder, nor shall any inspection by Owner
Participant, Lessor, the Trust Company, any Noteholder or Indenture Trustee be
deemed to affect or modify the provisions of this Section 5(a).

          (b) Exercise of Certain Rights under the Hughes Agreements.
              ------------------------------------------------------

               (i) STLC, in its capacity as Seller under the Purchase
Agreement, is making certain representations and warranties and undertaking
certain payment obligations to Lessor in its capacity as Buyer under the
Purchase Agreement
                                       20

with respect to the Transponders. The provisions of the Purchase Agreement have
been fully negotiated and represent the full and complete agreement of the
parties thereto with respect to the subject matter thereof. None of the
provisions of the Purchase Agreement are incorporated in this Lease and
LESSOR ACKNOWLEDGES THAT LESSEE, IN ITS CAPACITY AS LESSEE, HAS NOT MADE NOR
SHALL BE DEEMED TO HAVE MADE ANY REPRESENTATION OR WARRANTY, EXPRESS OR
IMPLIED, WITH RESPECT TO ANY TRANSPONDER, OR ANY PART THEREOF, IN THIS LEASE OR
ANY OF THE OTHER OPERATIVE DOCUMENTS, INCLUDING, WITHOUT LIMITATION, AS TO THE
TITLE, VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION, DESIGN, QUALITY,
DURABILITY, OPERATION, MERCHANTABILITY OR FITNESS FOR USE OR PURPOSE OF SUCH
TRANSPONDER, AS TO THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT
DISCOVERABLE, AS TO THE ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK OR
COPYRIGHT, OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR
IMPLIED, WITH RESPECT TO SUCH TRANSPONDER OR ANY PART THEREOF, EXCEPT AS
OTHERWISE SPECIFICALLY PROVIDED IN THE OPERATIVE DOCUMENTS. The foregoing is not
in any way intended to, nor shall it be deemed to, limit or otherwise affect the
obligations or representations or warranties of Lessee under Section 4.01 or
Article VI of the Participation Agreement, of Seller under the Purchase
Agreement or of Contractor under the Service Agreement.

               (ii) Lessor hereby agrees that so long as no Event of Default
shall have occurred and be continuing with respect to a Transponder, Lessor
shall not

                                      21
<PAGE>
 
exercise, during the Lease Term for such Transponder, any of its rights under
the Hughes Agreements in respect of such Transponder, including any of its
rights to any indemnity or other payments with respect to such Transponder;
provided that Lessee cannot waive the obligations of Seller or Contractor, and
- --------
Lessor may exercise any rights and remedies it might have, under Sections 5.01,
5.05, 8.01, 10.02, 15.10 and 15.12 of the Purchase Agreement and under Article 7
and Sections 2.1(b), 4.1, 4.2, 4.5, 4.7, 6.3, 13.10 and 13.12 of the Service
Agreement; provided, in addition that, notwithstanding anything to the contrary
           --------  -- --------
in the foregoing, Lessor shall at all times retain the right to defend its title
to the Transponders and to enforce its rights under the Lease or the Purchase
Agreement to cause Lessee or Seller to defend such title in accordance with the
provisions hereof or thereof. Lessor hereby authorizes Lessee, for so long as
this Lease shall be in effect with respect to any Transponder and so long as no
Event of Default shall have occurred and be continuing, to exercise in the name
of and on behalf of Lessor, the right and power to deal with the Seller and
Hughes Services under the Hughes Agreements and any other manufacturer or
supplier of such Transponder or any other users of the transponders on the
Satellite including, without limitation, the right to demand, receive, accept
and retain all services, tests, inspection rights, reports and other data and
services with respect to such Transponder as provided in the Purchase Agreement
and the Service Agreement, and the right to enforce (by legal action or
otherwise) or to elect not to enforce (except in such manner as would have a
material adverse effect on Lessor's interest in the Transponders upon expiration
or termination of the Lease) against such Seller, Hughes Services, other
manufacturer or supplier or other user all rights, powers and privileges of
Lessor, and to receive all benefits of Lessor with

                                      22
<PAGE>
 
respect to Seller (subject to Sections 12(c) and 12(d)), Hughes Services, such
other manufacturer or such supplier or such other user, under any express or
implied warranty or indemnity or other provisions of the Hughes Agreements or
substitute agreements in effect, pursuant to Section 7(b) or otherwise,
including, without limitation, the right to enforce (or not enforce (except in
such manner as would have a material adverse effect on Lessor's interest in the
Transponders upon the expiration or termination of the Lease)) and the right to
obtain and retain the benefits of, all rights and claims of Buyer under the
Purchase Agreement or of Owner under the Service Agreement; provided that
                                                            -------- ----
notwithstanding any term or provision of this Section 5(b)(ii) to the contrary,
Lessor and Owner Participant shall retain the right to any Excepted Payment
owing to either of them, respectively.

          (iii) If, notwithstanding the foregoing, Lessor receives any payment
of any kind whatsoever under the Purchase Agreement or the Service Agreement
during the Lease Term to which Lessee is entitled pursuant to Section 5(b)(ii),
Lessor shall upon receipt remit to Lessee the full amount of the payment
received by it under the Purchase Agreement, or the Service Agreement, as the
case may be; provided that no Payment Default, Bankruptcy Default or Event of
Default shall have occurred and be continuing; provided further, however, that
                                               -------- -------  -------
Lessor shall promptly remit such amounts to Lessee at such time as no Payment
Default, Bankruptcy Default or Event of Default is continuing.

     SECTION 6. Liens; Quiet Enjoyment; Assignment and Sublease.
                -----------------------------------------------

          (a) Liens. Lessee shall not directly or indirectly create, incur,
              -----
assume or suffer to exist any Lien on or with respect to any Transponder, the
Lessor's Estate or the
                                       23
<PAGE>
 
Indenture Estate, or title thereto or any interest therein, except Permitted
Liens. Lessee's obligations under this Section 6(a) with respect to any Lien,
other than Owner Participant Liens or Lessor's Liens, on any Transponder arising
prior to the termination of this Lease shall survive such termination.

          (b) Quiet Enjoyment. So long as no Event of Default shall have 
              ---------------
occurred and be continuing, as between Lessee and Lessor, Lessee shall have the
exclusive rights to possession and control of each Transponder and Lessor shall
not take any action that interferes with the quiet enjoyment of the use or non-
use of any Transponder by Lessee, and Lessee shall have the right to use or
not use such Transponder in its sole discretion.

          (c) Assignment, Sublease by Lessee. So long as no Event of Default
              ------------------------------
shall have occurred and be continuing, Lessee may, without the consent of or
prior notice to Lessor, assign its leasehold interest in whole or in part
(including any of Lessee's rights or options hereunder) in this Lease or
sublease, license, enter into short term or long term service contracts,
transfer Control of, or permit Seller or any other Person (including, without
limitation, to a "tax-exempt" entity as defined in Section 168(h) of the Code)
to use all or any part of any Transponder or Transponders during the Lease Term
(collectively the "Use Agreements") (such Use Agreements not including for the
purposes of Sections 6(c)(i), 6(c)(iv) and 6(c)(v) any occasional use service
contract for the provision of part-time, occasional use transponder capacity on
available Ku-band or C-band transponders on satellites, including the Satellite,
owned or operated by STLC or any Affiliate and not expressly required to be made
available on

                                       24
<PAGE>
 
the Satellite, an "Occasional Use Service Contract")), on and subject to the
following terms and conditions:

               (i) such Use Agreements shall expressly provide that the rights
     of any sublessee, assignee, user or operator thereunder (collectively,
     "User") are subject and subordinate to all the terms and conditions of this
     Lease, including, without limitation, Lessor's right to repossess any
     Transponder and terminate such Use Agreements upon the occurrence of an
     Event of Default;

               (ii) Lessee shall remain primarily liable to Lessor for the
     performance of all of the terms of this Lease to the same extent as if such
     Use Agreements had not occurred;

               (iii) such Use Agreements shall not be in violation of Applicable
     Law and the terms and conditions thereof shah not be inconsistent with the
     terms of this Lease, provided that the term thereof (as well as the term of
     any Existing Lease set forth in Exhibit D-1 or D-2, hereto) may extend
     beyond the expiration of the Lease Term, subject to the provisions of
     Section 6(e);

               (iv) such Use Agreements shall prohibit the User from entering
     into any Further Use Agreements without obtaining (x) the written consent
     of Lessee and (y) an agreement by any such User further transferring its
     rights to comply with the terms and conditions of this Section 6(c),
     including, without limitation, the requirement that any such Further Use
     Agreement be expressly subject and subordinate to this Lease; and

               (v) if Lessee is required to obtain or maintain casualty
     insurance pursuant to Section 9(b)(i), then within thirty (30) days
     following the date Lessee
                                       25
<PAGE>
 
      shall have Actual Knowledge of the existence of the conditions under
      Section 9(b)(i) that require Lessee to obtain or maintain such insurance,
      Lessee shall execute and deliver to Lessor an assignment agreement (in
      form and substance reasonably acceptable to Lessor) assigning to Lessor as
      additional security for all of Lessee's obligations hereunder its rights,
      with respect to the provision of transponder capacity on the Satellite
      only, under all Use Agreements, except that Lessee shall not be required
      to obtain a User's acknowledgment of or consent to such assignment nor to
      notify (and in connection therewith, Lessor hereby agrees not to notify)
      any User of such assignment unless an Event of Default shall have occurred
      and be continuing. Such assignment agreement shall provide that Lessee
      shall remain primarily liable to User to perform its obligations under
      such Use Agreement. 

Subject to the provisions of this Section 6(c), Lessee may render any
communications service, so long as the foregoing provisions of this Section 6(c)
shall apply, and Lessee or any Affiliate may provide Transponder or Transponders
capacity by Lessee or any Affiliate of Lessee to any of their respective
customers in the ordinary course of their respective businesses; provided that
no rendering of any such communications service or the providing of Transponder
or Transponders capacity, and neither the entering into or performing of any
agreement related thereto, shall operate to reduce, excuse or in any way affect
the obligations of Lessee hereunder and under the other Operative Documents to
which it is a party and as to which Lessee will remain primarily liable.

          (d) Existing Leases. As of the date hereof, Lessee is a party to
              ---------------
existing leases on certain Transponders, and the lessees under certain of such
leases are, in turn,

                                       26
<PAGE>
 
sublessors under subleases, which leases and subleases (not including any
Occasional Use Service Contract) are listed in Exhibit D-1 (as to the leases)
and Exhibit D-2 (as to the subleases) (collectively, the "Existing Leases").
                                                          ---------------
Contemporaneously with the execution and delivery of this Lease, Lessee is
assigning to Lessor, pursuant to the Assignment Agreement dated as of December
27, 1991 between STLC and Owner Trustee, as additional security for all of
Lessee's obligations hereunder its rights under such Existing Leases, with
respect to the provision of transponder capacity on any Transponder and on the
Satellite only (other than the Chevron, ISBN Space Segment Services Agreement
No. CITCO839, dated May 15, 1990); provided, however, that Lessee shall not be
                                   --------  -------
required to obtain an acknowledgment of or consent to such assignment from any
Sublessee under any Existing Leases or to notify, and in connection therewith
Lessor hereby agrees not to notify, any such Sublessees of the assignment unless
an Event of Default shall have occurred and be continuing; and provided,
                                                               --------
further, however, that Lessee shall remain primarily liable to such Sublessees
- -------  -------
to perform Lessee's obligations under the Existing Leases. In addition, Lessee
shall remain primarily liable to Lessor for the performance of all of the terms
of the Lease to the same extent as if such Existing Lease had not occurred.

          (e) Return of Transponders. (i) Any Use Agreement may by its terms
              ----------------------
extend, or be extended by the User, beyond the Lease Term and (ii) any Existing
Lease may be extended by the Sublessee beyond the Lease Term (a Transponder with
respect to which such Use Agreement or Existing Lease provides for such
extension, a "Selected Transponder"); provided that, each Transponder
                                      -------- ----
(including, but not limited to, any Selected Transponder) shall, at the time of
Redelivery to Lessor pursuant to Section 10,

                                      27
<PAGE>
 
be free and clear of any continuing obligation to any User, Sublessee or other
Person, unless Owner Participant shall otherwise expressly agree in writing at
the request of Lessee.

     SECTION 7. Operation; Maintenance; Compliance with Law; Location of
                --------------------------------------------------------
Satellite; Substitution of Transponders.
- ---------------------------------------

           During the Lease Term with respect to any Transponder:
 
           (a) Operation. Lessee shall observe and perform each and every
               ---------
obligation (and shall exercise all rights where failure to do so would have a
material adverse effect on Lessor's interest in the Transponders upon the
expiration or termination of the Lease) of Buyer under the Purchase Agreement
and Owner under the Service Agreement to the extent the same relate to such
Transponder, and shall keep the same in full force and effect. Lessee shall not
use any Transponder during the Lease Term or authorize any third party to use
such Transponder in breach of the Purchase Agreement, the Service Agreement or
any Applicable Laws applicable to Lessee, Lessor (in its capacity as such
Transponder owner without regard to Applicable Laws applicable to Lessor solely
because of it being engaged in a regulated activity of any type other than the
owning and leasing of the Transponder), Owner Participant (in its capacity as
such Transponder owner without regard to Applicable Laws applicable to Owner
Participant solely because of it being engaged in a regulated activity of any
type other than the owning and leasing of the Transponder), such third party or
such Transponder (in each case, other than Applicable Laws as to which
noncompliance would not have an Adverse Effect), or in violation of any
authorization relating to such Transponder or the Satellite or Lessee issued by
any Governmental Authority having jurisdiction over such

                                      28
<PAGE>
 
Transponder, the Satellite or Lessee (other than (i) any provision thereof as to
which noncompliance would not have an Adverse Effect or (ii) unless the validity
of such Applicable Law or authorization is being contested in good faith and by
appropriate proceedings (but only so long as such proceedings do not involve any
risk of civil or criminal liability to Lessor or Owner Participant, and do not
involve any material danger of the sale, forfeiture, loss or diminution in value
of such Transponder or the rights of Lessor or Owner Participant under any
Hughes Agreement or any Operative Document and adequate reserves with respect
thereto shall have been established in accordance with GAAP). As used herein,
"Adverse Effect" shall mean that which would materially adversely affect the
business, operations or properties of GMHE on a consolidated basis or involve
any material danger (x) of the loss of any FCC authorization to operate the
Satellite or maintain it in its assigned orbital location, (y) of any material
adverse effect on the ability of STLC to perform its obligations hereunder and
under the Purchase Agreement or of the sale, forfeiture, loss or diminution in
value of any Transponder, or (z) of the imposition of criminal or civil
liability on the Lessor or the Owner Participant.

          (b) Maintenance. Lessee hereby agrees to require Hughes Services to
              -----------
fulfill all of its obligations under the Service Agreement. STLC shall fulfill
all of its obligations under the Purchase Agreement. In connection therewith,
Lessee will make all payments required to be made during the Lease Term to
Hughes Services under the Service Agreement as Supplemental Rent pursuant to
Section 3(c)(iii), and will on behalf of Lessor perform all other obligations
thereunder required to be performed by Lessor, with respect to such Transponder
during the Lease Term. So long as during the Lease Term, the Service Agreement
or a Substitute Service Agreement shall have remained in

                                      29
<PAGE>
 
full force and effect and Hughes Services (or a Substitute Service Provider (as
defined below), if applicable) shall have performed all of its obligations
thereunder with respect to such Transponder, all maintenance, management and
monitoring responsibilities of Lessee in connection with such Transponder shall
be deemed fulfilled, and Lessee shall have no additional independent obligations
hereunder relating thereto.

          In the event that at any time during the Lease Term, the Service
Agreement shall no longer be in full force and effect or Hughes Services shall
fail to perform its obligations thereunder with respect to such Transponder,
Lessee, at its expense, shall maintain, manage and monitor, or cause to be
maintained, managed and monitored, the Satellite and such Transponder in good
working order and repair, ordinary wear and tear excepted, (i) in accordance
with the higher of (A) customary industry standards employed by owners of Ku-
band Transponders on domestic communications satellites or (B) standards at
least equal to those used by Hughes Services or any of its Affiliates prior to
such failure of performance for other transponders on the Satellite or on
another similar satellite owned, leased or operated by Hughes Services or any of
its Affiliates (if at the time Lessee or any Affiliate maintains, manages or
monitors satellites similar to the Satellite for similar commercial purposes);
(ii) in compliance with all Applicable Laws (other than Applicable Laws as to
which noncompliance would not have an Adverse Effect); and (iii) in accordance
with all applicable requirements of any insurance policy then in effect as
required by Section 9 hereof. The foregoing notwithstanding, if, with respect to
any Transponder, Contractor or Substitute Service Provider is unable temporarily
to perform its maintenance obligations under the Service Agreement or any
Substitute Service Agreement due to any

                                      30
<PAGE>
 
Force Majeure Event, then, provided such temporary failure to perform does not
cause a permanent material diminution in the value of such Transponder and is
capable of cure before any such permanent diminution in value would result, such
failure shall not constitute a breach of Lessee's obligations under this Lease.

          Without limiting the generality of the foregoing, at any time during
the Lease Term, if the Service Agreement shall not be in effect, Lessee will
arrange for Lessor to enter into and Lessee will keep in full force and effect
for the remainder of the Lease Term an agreement for the provision of services
(the "Substitute Service Agreement") comparable to those to be provided by
      ----------------------------
Hughes Services under the Service Agreement at a reasonable cost with a sound
and reputable service provider, which may or may not be an Affiliate of Hughes
Services (the "Substitute Service Provider"), and which such provider shall be
               ---------------------------
reasonably acceptable to Owner Participant. If Lessor enters into a Substitute
Service Agreement, it will assign its rights under such agreement to Lessee
during the Lease Term on the terms and conditions contained in Section 5(b)(ii).

          (c) Compliance with Law. During the Lease Term with respect to any
              -------------------
Transponder, Lessee or Contractor shall have and maintain all permits, licenses
and approvals required by the FCC or under any Applicable Law to operate the
Satellite and such Transponder and shall satisfy the requirements of the FCC and
any statute, regulation or order applicable to operators, users or lessees of
such Transponder; provided, however, that Lessee shall not be deemed to have
                  --------  -------
breached the foregoing covenant unless such non-maintenance or non-satisfaction
would have an Adverse Effect. To the extent permitted by law, Lessee or any
Affiliate shall prepare and file in timely

                                      31
<PAGE>
 
fashion, or, where Lessor, Owner Participant or Indenture Trustee shall be
required so to file, prepare and deliver to such Person within a reasonable time
prior to the date for filing, any reports with respect to any Transponder which
are required to be filed with any Governmental Body during the Lease Term for
such Transponder. Lessor shall notify Lessee promptly after Lessor has Actual
Knowledge of any reports or filings required of Lessor by law in connection with
its ownership of the Transponders; provided, however, that Lessor shall not
                                   --------  -------
incur any liability to Lessee for failure so to notify Lessee. If Lessee shall
fail to timely prepare, deliver or file any such report solely as a result of
the failure of Lessor, Owner Participant or Indenture Trustee timely to provide
Lessee with (i) any information required in such report which is in the
possession of Lessor, Owner Participant or Indenture Trustee and is not
reasonably available to Lessee or (ii) notice of the requirement of such report
if such report is required as to Lessor, Owner Participant or Indenture Trustee
for any reason other than such Person's interest in the Transponder or
Transponders then subject to this Lease, Lessee shall incur no liability to any
such Person failing to provide such information or notice, to the extent such
liability is incurred by the failure to provide such information. Lessor hereby
appoints Lessee its attorney-in-fact, to the extent permissible by Applicable
Law, to execute such reports in the name of Lessor and to file such reports, and
Lessor shall cooperate in furnishing Lessee such information as is available to
it which must be included in such reports. Upon demand, Lessee shall reimburse
Lessor, Owner Participant or Indenture Trustee on an After-Tax Basis for any
reasonable out-of-pocket costs incurred by each such Person, respectively, in
connection with the preparation and filing of any such reports. Lessee shall, on
a periodic basis, furnish

                                      32
 
<PAGE>
 
Lessor, Owner Participant or Indenture Trustee a copy of all reports filed by
Lessee on behalf of any such Person pursuant to this Section 7(c).  


          (d) Location of Satellite.
              ---------------------

          (i) Except as set forth in Section 7(d)(ii), Lessee may, upon receipt
of all necessary government approvals and permissions, and in accordance with
all Applicable Laws, at any time or times during the Lease Term, move the
Satellite to a different assigned orbital location; provided, however, that any
                                                    --------  ------- 
such move may be made only (1) at any time or times if required to comply with a
requirement of the FCC and not voluntarily sought by Lessee or any of its
Affiliates (an "FCC Ordered Move"); provided that Lessee shall contest in a
                ----------------    --------
commercially reasonable manner any proposed FCC Order requiring a new permanent
assignment of the Satellite to an orbital location outside the Authorized Range
and any temporary assignment of the Satellite to a location outside the
Authorized Range if Lessee has reason to expect, after consideration of the
available information, that moving the Satellite to such temporary location and
returning it to a location in the Authorized Range would result in the Satellite
failing to meet the Minimum Fuel Requirement at the time of Redelivery pursuant
to Section 10; (2) at any time or times during the Lease Term at the sole
discretion of Lessee (a "Discretionary Move"); provided, however, that a move
                         ------------------    --------  -------
to 72 degrees West Longitude shall constitute a Discretionary Move; provided
                                                                    -------- 
further that no more than two Discretionary Moves may be made by Lessee; and 
- -------                                                  
provided further that if Lessee shall renew the Lease and any such renewal term
- -------- -------                                          
shall be for the remainder of the Transponders' useful commercial life, then
Lessee shall be entitled to make during such Renewal Term one additional
Discretionary Move; (3) at any time during the Lease Term, if the move (an
"Emergency
 ---------

                                      33
<PAGE>
 
Move") is to be made to the then FCC authorized orbital location of either (x)
- ----
the satellite commonly known as Galaxy IV (presently authorized at 99 degrees
West Longitude) or (y) Galaxy VII (presently authorized at 91 degrees West
Longitude) (or, in either case, for any replacement satellite therefor) in order
to fulfill Lessee's then-existing contractual commitments to transponder
purchasers, lessees or other users of transponder capacity on such satellites
which relate to late delivery, delivery failure or catastrophic failure; (4) if
necessary for Lessee to comply with its obligation to redeliver the Transponders
in an orbital location within the Authorized Range as provided in Section 10; or
(5) at any time after Lessee shall have exercised its option to acquire the
Transponders under Section 20(c), in which later case the provisions of this
Section 20(c), where applicable, shall apply.

          (ii) Lessee's right to move the Satellite as provided in Section
7(d)(i) is subject to the satisfaction of the following conditions:

          (A) prior to Lessee's receipt of a license or other authorization from
    the FCC to locate the Satellite in an orbital location within the Authorized
    Range for its remaining useful commercial life (the "Permanent Location"),
    Lessee cannot use a Discretionary Move to move the Satellite to an orbital
    location outside of the Authorized Range (an "Alternative Location") unless
                                                  ----------- --------
    Lessee shall then have authorization to return the Satellite to an orbital
    location within the Authorized Range or at 72 degrees West Longitude and
    Lessee has reason to expect, after consideration of the available
    information, that such move to an Alternative Location and return to either
    72 degrees West Longitude or an orbital position in the Authorized Range to
    which Lessee reasonably believes the Satellite shall be

                                      34
<PAGE>
 
    authorized to return would not result in the Satellite failing to satisfy
    the Minimum Fuel Requirement applicable at the time of Redelivery pursuant
    to Section 10;

        (B) after receipt by Lessee of a license or other authorization from the
    FCC to locate the Satellite in the Permanent Location, Lessee may make a
    Discretionary Move of the Satellite to an Alternative Location only if (x)
    the Satellite shall be moved to such Alternative Location on a temporary
    basis, and Lessee shall then have the authorization to return the Satellite
    to the Permanent Location on or prior to the end of the Lease Term, and (y)
    Lessee has reason to expect after consideration of available information
    that such move to an Alternative Location and return to the Permanent
    Location would not result in the Satellite failing to satisfy the Minimum
    Fuel Requirements applicable at the time of Redelivery pursuant to Section
    10;

        (C) any move of the Satellite pursuant to this Section 7(d) will be made
   in accordance with such industry standards as are practiced when moving
   satellites to a different orbital location and taking into account the
   circumstances surrounding any such move (including, the necessity to move the
   Satellite on a rapid basis when making an Emergency Move); and

        (D) in no case, except for an FCC Ordered Move, will Lessee move the
   Satellite to an orbital location outside of the orbital arc between and
   including 72 degrees and 105 degrees West Longitude.

        (e) Substitution of Transponders. Lessee shall have the right subject to
            ----------------------------
the conditions set forth in the following paragraph to substitute a transponder
(a

                                      35
<PAGE>
 
"Replacement Transponder") aboard the Satellite for any Transponder which has
 -----------------------
suffered an Event of Loss. Upon fulfillment of the conditions specified in this
Section 7(e), such Replacement Transponder shall be conveyed by Lessee to Lessor
and leased to Lessee hereunder.

          The substitution of a transponder pursuant to this Section 7(e) shall
be subject to fulfillment of the following conditions precedent prior to or on
the date of the proposed substitution to the reasonable satisfaction of Lessor
and at Lessee's sole cost and expense: (i) if the Lease is in effect with
respect to such Transponder, no Bankruptcy Default or Event of Default shall
have occurred and be continuing or will exist immediately following the proposed
substitution; (ii) on the date of such substitution, the Replacement Transponder
(A) shall meet the Transponder Performance Specifications set forth in Appendix
C to the Purchase Agreement, (B) shall have a total useful commercial life of 15
years or more as measured from the Delivery Date, and (C) can reasonably be
expected to continue to meet such performance specifications for such period of
15 years or more as measured from the Delivery Date (all of (A), (B) and (C) as
determined pursuant to the Appraisal Procedure); (iii) Lessor shall have
received a bill of sale substantially in the form of the Bill of Sale conveying
title to such Replacement Transponder to Lessor; (iv) if so requested by Lessor,
or for so long as the Indenture shall be in effect by Indenture Trustee, Lessee
shall have entered into a Lease Supplement covering such Replacement Transponder
and, if so requested by Indenture Trustee, the Lessor shall have delivered an
Indenture Supplement to Indenture Trustee; (v) Lessor shall have good and
marketable title to such Replacement Transponder free and clear of all Liens
other than Permitted Liens of the type discussed in clauses (a) and

                                      36
<PAGE>
 
(b) of the definition thereof; (vi) such Replacement Transponder shall be
covered by an assignment and consent instrument similar in form and substance to
the Consent and Agreement; (vii) Lessee shall have made arrangements reasonably
satisfactory to Lessor for Lessor to enter into the Service Agreement or the
Substitute Service Agreement or, if not then in effect, a service agreement
reasonably acceptable in form and substance to Lessor with respect to the
Replacement Transponder; (viii) no such substitution shall occur at any time
after the tenth anniversary of the Delivery Date; and (ix) Owner Participant
shall have received (a) an opinion of its tax counsel that Owner Participant
will not suffer any adverse tax consequences as a result of such substitution
(other than any such adverse tax consequences as would result from such
substitution under the Code or Regulations as in effect as of the Delivery Date)
and (b) an indemnity from Lessee satisfactory in form and substance to Owner
Participant for any such adverse tax consequences relating to such substitution
as Owner Participant may reasonably request. Upon the fulfillment of the
foregoing conditions, Lessor will Transfer to Lessee all of Lessor's right,
title and interest in and to the Transponder to be replaced as is, where is,
free and clear of all Lessor Liens and Owner Participant Liens, but otherwise
without warranty, and will deliver to Lessee such instrument as Lessee shall
reasonably request releasing such Transponder from this Lease. Upon such
substitution for all purposes hereof, such Replacement Transponder shall be
deemed to be a "Transponder" hereunder.

SECTION 8. Termination.
           -----------

     (a) Early Termination.
         -----------------

          (i) Provided that no Payment Default, Bankruptcy Default or Event of
Default shall have occurred and be continuing, in the event that Lessee shall in
good faith determine that the Transponders, in the aggregate, have become
uneconomic, obsolete or surplus to Lessee's requirements (as evidenced by a
resolution to such effect adopted by the Board of Directors of HCI (the parent
of STLC)), Lessee shall have the option, during the Basic Term (and not during
any Renewal Term), upon furnishing a notice to Lessor and Indenture Trustee at
least 180 days prior to the effectiveness thereof to terminate this Lease with
respect to all, but not less than all, of the Transponders on any Rent Payment
Date on or after the date shown as Item 6 on Schedule E hereto (the "Termination
                                                                     -----------
Date"). As a condition to any transfer by Lessor of the Transponders or
- ----
retention by Lessor of the Transponders (each pursuant to this Section 8), any
necessary regulatory approvals in connection therewith shall have been obtained
(Lessee hereby agreeing to use reasonable best efforts to obtain or to assist
Lessor in obtaining such approvals).

          During the period from the giving of such notice of termination for
the Transponders until 60 days prior to the Termination Date, Lessee, as non-
exclusive agent for Lessor, shall use commercially reasonable efforts to solicit
unconditional cash bids from Persons other than Lessee or its Affiliates (it
being understood for the purposes of this Section 8 that "Affiliates" shall
include any other Person directly or indirectly controlling, directly or
indirectly controlled by,

                                       38
<PAGE>
 
or under direct or indirect common control with, Lessee) to purchase such
Transponders on the Termination Date, and Lessee shall, during the period from
the giving of such notice of termination until 60 days prior to the Termination
Date (as set forth in the preceding paragraph), from time to time at the request
of Lessor or Indenture Trustee, inform Lessor and Indenture Trustee of the
results of its efforts and shall certify to Lessor and Indenture Trustee, at
least 60 days prior to the Termination Date, the amount and terms of each such
bid which has theretofore been submitted and the name and address of the party
submitting such bid. Lessor and Owner Participant shall each have the right to
solicit bids (or each to make its own bid, provided that any bid by Lessor or
Owner Participant shall be submitted to Lessee prior to the disclosure by Lessee
to Lessor or Owner Participant of any other bids), but shall be under no duty to
solicit bids or to inquire into the efforts of Lessee to obtain bids. Each such
bid (a) shall be for payment in full in cash and (b) shall not involve any
consideration to be received by Lessee or its Affiliates or be connected,
directly or indirectly, with any transaction between the purchaser and the
Lessee or its Affiliates, (collectively, a "Bona Fide Bid"). On or prior to the
                                            -------------
40th day prior to the Termination Date, Lessee may (provided that Lessee has not
previously canceled a proposed termination except for a deemed cancellation as
provided in Sections 8(a)(ii) and 8(c) hereto), by notice to Lessor and
Indenture Trustee, cancel the proposed termination of this Lease for the
Transponders, whereupon this Lease shall continue in full force and effect with
respect to the Transponders.
 
                                      39
 
<PAGE>
 
         If Lessee does not cancel such proposed termination as set forth in the
last sentence of the preceding paragraph and any Bona Fide Bids are received on
or prior to the 60th day before the Termination Date, Lessee's notice of
termination shall become irrevocable on the 10th Business Day prior to the
Termination Date and Lessor shall on the Termination Date, provided that the
conditions of subsection (b) have been fulfilled, sell such Transponders to the
bidder which shall have submitted the highest Bona Fide Bid for such
Transponders and which has not defaulted on its bid (or to the next successively
highest bidders, if any, which shall have submitted Bona Fide Bids, in the case
of a default by the prior bidder, provided such sale shall have been consented
to by Lessee if the Bona Fide Bid related thereto is for an amount less than the
applicable Termination Value for the Transponders) for such Transponders upon
receipt in immediately available funds of the amount specified in such bid. Such
funds shall be paid either to Indenture Trustee or to Lessor, as required
pursuant to the Indenture. All reasonable out-of-pocket costs and expenses
incurred by Lessor or Indenture Trustee including, without limitation,
attorneys' fees, in connection with any notice of termination, regardless of
whether a sale is completed or Lessee withdraws its notice of termination, shall
be paid by Lessee on an After-Tax Basis.

          (ii) If no sale of the Transponders shall have occurred in accordance
with Section 8(a)(i) on the Termination Date, or if all bidders having submitted
Bona Fide Bids for such Transponders that were for an amount at least equal to
Termination Value for the Transponders (or if for less than such

                                      40
<PAGE>
 
Termination Value, the sale to such bidder was consented to by Lessee) have
defaulted on such bids, then the Lease shall continue in full force and effect
and the termination notice given by Lessee shall be deemed to have been
cancelled by Lessee. If no sale of the Transponders shall have occurred in
accordance with Section 8(a)(i), as a result of a default by Lessor in its
obligation to sell the Transponders in accordance with Section 8(b), then Lessor
shall have been deemed to have exercised its election to retain ownership of the
Transponders pursuant to Section 8(c) hereof.

     (iii) Notwithstanding anything to the contrary in this Section 8(a), if the
bidder to whom the sale would otherwise have taken place shall have defaulted on
its bid within the 10 Business Day period prior to the Termination Date, Lessee
shall nonetheless make, on the Termination Date, all the payments specified in
Section 8(b) (other than the payment pursuant to the second sentence of Section
8(b)) and payment of Termination Value for the Transponders as of the
Termination Date. Promptly thereafter, Lessor shall use its reasonable
commercial efforts to sell the Transponders to an unaffiliated third party.
Lessor shall retain the net proceeds of any such sale in excess of Termination
Value for such Transponders as of the Termination Date. The net proceeds of such
sale up to but not exceeding Termination Value for such Transponders as of the
Termination Date shall be paid by Lessor to Lessee within 5 Business Days of
receipt of the proceeds of such sale. Upon payment by Lessee of all the amounts
due pursuant to this Section 8(a)(iii), the obligation of Lessee to pay Base
Rent with respect to the Transponders and Supplemental Rent, other than to pay
 
                                      41
 
<PAGE>
 
     Supplemental Rent attributable to acts, events or conditions occurring or
     existing on or prior to such termination with respect to such Transponder,
     shall terminate, such Transponder shall no longer be subject to this Lease
     and the Lease Term with respect to such Transponders shall end.

          (b) Termination Payments. As a condition to the obligation of Lessor
              --------------------
to terminate the Lease and to sell the Transponders pursuant to Section 8(a) on
the Termination Date therefor, Lessee shall on the Termination Date pay to
Lessor the sum of (A) all amounts of Base Rent for such Transponders due and
unpaid prior to such Termination Date and (B) in the event that the Termination
Date is a Rent Payment Date on which a Scheduled Rent payment designated as an
"arrears rent" on Schedule A hereto as adjusted pursuant to Section 4 is due,
the sum of any Scheduled Rent with respect to such Transponders designated as an
"arrears rent" on Schedule A hereto as adjusted pursuant to Section 4 and due on
such Termination Date, and the Rent Differential Amount with respect to such
date, if any, and (C) any other Rent then due with respect to such Transponders,
including Premium, if any, on the outstanding Notes. In addition, Lessor shall
retain the net proceeds of the sale of such Transponders and Lessee shall pay to
Lessor the excess, if any, of Termination Value for the Transponders (computed
as of the Termination Date) over such net sales proceeds. Upon payment by Lessee
of the amounts due pursuant to this Section 8(b), the obligation of Lessee to
pay Base Rent and Supplemental Rent, other than to pay Supplemental Rent
attributable to acts, events or conditions occurring or existing on or prior to
such termination with respect to such Transponders, shall terminate, such
Transponders shall no longer be subject to this Lease and the Lease Term with
respect to such Transponders shall end.

                                      42
<PAGE>
 
          (c) Retention of Transponders by Lessor. If Lessee shall elect to
              -----------------------------------
terminate this Lease pursuant to Section 8(a), Lessor may, subject to Lessee's
right to cancel the proposed notice of termination, elect to retain rather than
sell the Transponder by giving irrevocable notice to Lessee and Indenture
Trustee no later than 45 days prior to the Termination Date. If Lessor so elects
to retain the Transponders, on the Termination Date (i) Lessor shall pay to
Indenture Trustee an amount equal to the unpaid principal amount of, and
Premium, if any, due on the outstanding Notes and (ii) Lessee shall pay to
Lessor or the Person entitled thereto as provided in the Operative Documents (A)
(i) all Base Rent with respect to the Transponders due prior to the Termination
Date and (ii) in the event that the Termination Date is a Rent Payment Date on
which a Schedule Rent payment designated as an "arrears rent" on Schedule A
hereto as adjusted pursuant to Section 4 is due, the sum of any Scheduled Rent
with respect to the Transponder designated as an "arrears rent" on Schedule A as
adjusted pursuant to Section 4 due on such Termination Date and the Rent
Differential amount with respect to such date, if any, and (B) all other Rent
(other than any amounts required to be paid by Lessee pursuant to the second
sentence of Section 8(b)) due and owing on or prior to the Termination Date,
including Premium, if any, on the outstanding Notes, (iii) this Lease and the
obligations of Lessee hereunder shall terminate, other than to pay Supplemental
Rent attributable to acts, events or conditions occurring or existing on or
prior to such termination, and (iv) Lessor shall execute and deliver to Lessee,
at Lessee's reasonable expense, such instruments as Lessee shall reasonably
request to evidence the termination of this Lease. In the event Owner
Participant fails to make funds available to Owner Trustee to enable Lessor to
pay the

                                      43
<PAGE>
 
amounts specified in clause (i) of this Section 8(c) or Lessee fails to pay the
amounts specified in clause (ii) of such sentence, Lessee shall be deemed to
have cancelled its notice of termination and the Lease shall continue in full
force and effect (and in the case of Lessor's failure to pay the amounts set
forth in clause (i), above, Lessee shall have the right to enforce the
obligations of Owner Participant as set forth in Section 5.02(j) of the
Participation Agreement). 

          (d) No Duplication of Rent Differential Amount. In the event that a
              ------------------------------------------
portion of the Scheduled Rent due on any Termination Date is designated as an
"arrears rent" on Schedule A and there is also a payment of Scheduled Rent due
on such Termination Date that is not so designated, a portion of the Rent
Differential Amount with respect to such Termination Date shall be added to the
Scheduled Rent designated as an "arrears rent" due on such date and the
remainder of such Rent Differential Amount shall be taken into account in the
computation of Termination Value pursuant to the definition of Termination
Value. It is intended that the entire amount of the Rent Differential Amount due
on such Termination Date shall be allocated between the Scheduled Rent
designated as an "arrears rent" due on such date and the computation of
Termination Value, as appropriate and without duplication, in such manner as
will preserve the Owner Participant's Net Economic Return and comply with the
minimum payment requirement (it being understood that the entire amount of such
Rent Differential Amount shall be taken into consideration in making such
allocation).

     SECTION 9. Insurance.
                ---------

          (a) Liability Insurance. Lessee shall not be required to obtain
              -------------------
general liability insurance in respect of the Satellite or any of the
Transponders, unless it shall carry such insurance for similar events or
occurrences on other satellites or transponders it or any of its Affiliates owns
or leases from third parties, in which case it shall carry such liability
insurance on the Satellite or Transponder in the amount and on terms and for
similar events or occurrences and against risks comparable to those applicable
to such other satellites or transponders. Lessee shall not, however, have any
obligation to carry or continue to carry any such liability insurance on any
such other satellite or transponders. Lessee agrees that it shall not take any
action to induce any of its liability insurers to increase the premiums charged
for existing liability insurance with respect to the Transponders or to seek to
remove such Transponders from coverage under any such policy, unless Lessee, in
its discretion, shall determine that the premium paid for, or attributable to,
such general liability insurance is commercially unreasonable.

          (b) Insurance Against Loss or Damage.
              --------------------------------

               (i) Requirement to Obtain and Maintain. During the Lease Term
                   ----------------------------------
     with respect to any Transponder, if at any time (a) the Moody's Credit
     Rating is Baa2 or lower or (b) the Standard & Poor's Credit Rating is BBB
     or lower or (c) GMHE's Tangible Net Worth is less than $3.5 billion, then
     within thirty (30) days following the date that Lessee shall have Actual
     Knowledge that any of the foregoing conditions exist, Lessee shall obtain
     and maintain, for the period that any such condition continues to exist,
     life or casualty insurance with respect to the Transponders, on standard
     industry terms and conditions, in an amount equal to

                                       45
<PAGE>
 
    (x) Stipulated Loss Value for the Transponders from time to time without any
    deductible; except that Lessee shall not be required to obtain such
    insurance if Lessor in its sole discretion waives such requirement upon
    written request by Lessee therefor. In addition, Lessor may in its sole
    discretion permit a deductible upon written request by Lessee therefor. If
    at any time during the Lease Term (A) the Notes are not rated Investment
    Grade by either of Moody's or Standard & Poor's and (B) GMHE's Tangible Net
    Worth is less than $3.5 billion, then, within thirty (30) days following the
    date that Lessee shall have Actual Knowledge that the conditions described
    in clauses (A) and (B) exist, Lessee shall obtain, for the period that both
    of such conditions continue to exist, life or casualty insurance with
    respect to the Transponders, on standard industry terms and conditions, in
    an amount, if any, equal to (x) Stipulated Loss Value for the Transponders
    from time to time, subject to a deductible with Lessor's written consent in
    an amount not greater than 1.5% of GHME's Tangible Net Worth, as of the date
    of such insurance policy (with such deductible amount being subject to re-
    adjustment on the expiration date for such policy, based on the most recent
    public financial report of GMHE) (the "Permitted Deductible"). If, at any
                                           --------------------
    time during the Lease Term, (1) the Moody's Credit Rating is Ba2 or lower or
    (2) the Standard & Poor's Credit Rating is BB or lower or (3) GMHE's
    Tangible Net Worth is less than $3 billion, then Lessee shall carry for the
    period that any of the conditions described in clauses (1) or (2) or (3)
    continues to exist, such policy for the full amount of Stipulated Loss Value
    for the Transponders without any deductible.

               (ii) Non-Discrimination. At all times during the Lease Term,
                    ------------------
          Lessee will maintain life or casualty insurance in an amount and type
          for the Transponders that is not significantly different from the life
          or casualty insurance that Lessee maintains, in its sole discretion,
          for comparable transponders owned or operated by Lessee or its
          Affiliates; provided, however, that the foregoing shall not require
                      --------  -------
          Lessee to maintain life or casualty insurance for the Transponders in
          an amount in excess of Stipulated Loss Value for such Transponders
          subject to the Permitted Deductible.

               (iii) Letter of Credit. If at any time during the Lease Term,
                     ----------------
          Lessee is required to carry insurance against loss or damage for the
          Transponders, Lessee may, in lieu of or in combination with, carrying
          such insurance, provide a letter of credit from an Eligible Bank
          reasonably acceptable to Lessor, which in combination with any
          insurance carried by Lessee, shall be in an amount corresponding to
          the Stipulated Loss Value for the Transponders from time to time
          (minus the Permitted Deductible or such other permitted deductible, if
          applicable).

          (c) Additional Insureds. All insurance policies, if any, carried in
              -------------------
    accordance with Section 9(a) and all policies taken out in substitution or
    replacement for any such policies (i) shall name Lessor (in its individual
    capacity and as Owner Trustee), Owner Participant, and Indenture Trustee,
    as additional insureds, as their respective interests may appear (but
    without imposing upon any such parties any obligation imposed upon the
    insured, including, without limitation, the liability to pay the premium for
    such policies) and in the case of life or casualty insurance pursuant to
    Section 9(b),
 

                                       47
<PAGE>
 
    Indenture Trustee, and within 30 days after the Delivery Date Lessor, shall
    be named as "loss payees", as their interests may appear; (ii) shall provide
    that any loss (other than a loss under third party liability insurance)
    shall be adjusted by the Lessee with the insurance carriers and be payable
    to the Lessor (or, so long as the Indenture shall be in effect, the
    Indenture Trustee), for application as provided in Section 12 hereof or
    Section 5.4 of the Indenture; and (iii) shall provide that if such insurance
    is changed in any material respect in relation to the interests of the
    Lessor or Owner Participant (and for so long as the Indenture shall be in
    effect, Indenture Trustee), or if such insurance is allowed to lapse for 
    non-payment of premium, or is invalidated by any action or inaction of
    Lessee or any other Person (other than action or inaction by Lessor, Owner
    Participant or Indenture Trustee, as the case may be), such change, lapse or
    invalidation shall not be effective as to Lessor, Owner Participant and (so
    long as the Indenture shall be in effect) Indenture Trustee for at least 30
    days after receipt by Lessor, Owner Participant and (so long as the
    Indenture shall be in effect) Indenture Trustee of written notice from such
    insurers, their agents or the Lessee of such lapse. Each insurance policy
    provided under this Section 9 shall be primary without right of contribution
    from any other insurance which is carried by Lessor, Owner Participant or
    Indenture Trustee with respect to their respective interests as such in the
    Transponders.

         (d) Separate Insurance. Nothing contained in this Lease shall prevent
             ------------------
    Lessor, Owner Participant, Indenture Trustee or Lessee, each at its own
    expense and for its exclusive benefit, from carrying excess casualty
    insurance covering the Transponders in addition to the casualty insurance,
    if any, carried by Lessee under Section 9(b) (any such additional casualty
    insurance being herein called "Additional Insurance"); provided,
                                                           --------

                                       48
<PAGE>
 
however, that Lessee shall not be entitled to obtain any such Additional
- -------
Insurance for the Transponders unless Lessee shall then maintain insurance for
such Transponders pursuant to Section 9(b) in an amount at least equal to the
Stipulated Loss Value for such Transponders from time to time set forth in
Schedule B corresponding to such date, subject to customary industry deductibles
or the deductibles permitted pursuant to Section 9(b), if applicable. If there
shall be any limitation with respect to the amount of Additional Insurance that
Lessor, Owner Participant, Indenture Trustee or Lessee may obtain, whether as a
result of market capacity or otherwise, then each such party shall have the
right to purchase an amount of Additional Insurance for the Transponders as its
interests may then appear. Prior to obtaining any Additional Insurance, Lessor,
Owner Participant or Indenture Trustee shall provide Lessee with reasonable
notice of the Additional Insurance (including the proposed terms thereof)
intended to be obtained by it, including evidence satisfactory to Lessee that
such proposed terms shall be consistent with the terms of such insurance as may
be carried by Lessee under Sections 9(a), 9(b) or 9(c).

   SECTION 10. Redelivery.
               ----------
 
         (a) Acceptable Redelivery. At the expiration or earlier termination of
             ---------------------
    the Lease Term with respect to any Transponder, if Lessee does not renew
    this Lease with respect to such Transponder and does not purchase such
    Transponder, Lessee shall at Lessee's cost and expense redeliver such
    Transponder to Lessor on the Satellite in the condition required by Section
    7 hereof and with the Satellite (i) being located in an orbital location
    authorized by the FCC for the remaining useful commercial life of the
    Satellite that is in the Authorized Range, (ii) having been located in such
    orbital location

                                       49
<PAGE>
 
    for a period of no less than the thirty (30) consecutive months prior to
    the date of such Redelivery (or being located at any other orbital location
    as a result of an Emergency Move with no requirement that the Satellite be
    located in such orbital location for any period of time) pursuant to an FCC
    authorization which would allow it to remain in such orbital location for
    the Satellite's remaining useful commercial life (this clause (ii), the
    "Residency Requirement"), and (iii) meeting the Minimum Fuel Requirement
    (satisfaction of the requirements set forth in clauses (i), (ii) and (iii)
    collectively being referred to as an "Acceptable Redelivery"). If Lessee's
    Redelivery of any Transponder is other than an Acceptable Redelivery, then
    the parties shall have the rights and obligations set forth in Section 10(c)
    or Section 10(d). If an Acceptable Redelivery is made, Lessor must accept
    such Redelivery, subject to Section 10(b), and Lessee shall have no
    obligation under Section 10(c) or 10(d).

         (b) Redelivery Terms. In the event of any Redelivery of any
             ----------------
    Transponder, Lessee shall execute and deliver to Lessor an instrument
    substantially in the form of Exhibit C to this Lease that shall constitute
    evidence of surrender by Lessee of all of Lessee's rights to such
    Transponder under this Lease and the Hughes Agreements applicable thereto;
    provided, however, that Lessee's Redelivery of any Transponder hereunder
    --------  -------
    shall not by itself affect the validity and effectiveness of the Purchase
    Agreement, Service Agreement or any Substitute Service Agreement relating to
    such Transponder, as applicable. At the time of any Redelivery, such
    Transponder shall be free and clear of all Liens (other than Permitted Liens
    described in clauses (a) and (b) of the definition thereof, excluding Lessor
    Liens and Indenture Trustee Liens) and free and clear of any right of any
    Person to use or access such Transponder other than Lessor

                                       50
<PAGE>
 
or Owner Participant unless Owner Participant shall consent to a request by
Lessee to recognize any right of any Person to use or access such Transponder
other than Lessor and Owner Participant; and Lessee shall be in compliance with
Sections 7(b) and (c).

    (c) Rejectable Offer. If at the time of Redelivery of any Transponder (other
        ----------------
than a Redelivery pursuant to Section 8), the Satellite will (A) fail to meet
the Minimum Fuel Requirement, or (B) be located in an orbital location outside
the Authorized Range other than as a result of the failure of STLC to pursue in
a commercially reasonable manner authority to locate the Satellite in an orbital
location within the Authorized Range or (C) not have been in its orbital
location at redelivery for a period of 30 consecutive months by reason of an
Emergency Move (an "Emergency Relocation") or an FCC Ordered Move; then, as the
remedy for its failure to make an Acceptable Redelivery, Lessee shall make an
offer to Lessor (the "Rejectable Offer"), no earlier than 540 days and no later
                      ----------------
than thirty (30) days prior to the scheduled date of such Redelivery, to
purchase such Transponder in lieu of Redelivery for a purchase price (the "Offer
                                                                           -----
Amount") equal to (i) 12% of Buyer's Cost for such Transponder if such
- ------
Redelivery is at the end of the Basic Term or (ii) 2.4% of Buyer's Cost if such
Redelivery is at the end of the First Renewal Term. Lessor shall inform Lessee
whether it shall accept or reject such Rejectable Offer within ninety (90) days
of receipt of the Rejectable Offer if made 180 days or more prior to the
scheduled date of such Redelivery and within fifteen (15) days of receipt of the
Rejectable Offer if made less than 180 days prior to the scheduled date of such
Redelivery. If Lessor timely rejects the Rejectable Offer, or fails timely to
accept or reject such offer, then Redelivery of the Satellite shall occur at the
end of the Lease Term pursuant to Section 10(b) and such

                                       51
<PAGE>
 
Redelivery shall be deemed an Acceptable Redelivery. If Lessor timely accepts
the Rejectable Offer, then Lessee shall retain Control of the Transponders, and
pay the Offer Amount to Lessor on the last day of the Lease Term, together with
any and all Rent due and owing; and concurrently, Lessor shall transfer title
to such Transponder to Lessee as is, where is, free and clear of all Lessor
Liens and Owner Participant Liens, but otherwise without warranty, by executing
and delivering to Lessee an instrument substantially in the form of Exhibit C
to the Lease.

     If Lessee does not purchase the Subsequent Purchase Option on or before the
Subsequent Purchase Option Cut-off Date, and subsequent thereto (during the
Lease Term), Lessee makes an Emergency Move of the Satellite, any Redelivery of
the Transponders at the termination of the Lease Term shall occur at the orbital
location at which the Satellite was located immediately prior to such Emergency
Move (unless Lessor, in its sole discretion, shall consent to Redelivery to
another orbital location, then to such other location), and the parties shall
otherwise have the rights and obligations with respect to such Redelivery as set
forth in Section 10(c).

     (d) Rejectable Offer; Decreased Value. If at the time of Redelivery of any
         ---------------------------------
Transponder (other than a Redelivery pursuant to Section 8), the Satellite will
(A) fail to meet the Residency Requirement for any reason other than an
Emergency Relocation or an FCC Ordered Move or (B) be outside the Authorized
Range due to the failure of STLC to pursue in a commercially reasonable manner
authority to locate the Satellite in an orbital location for the Satellite
within the Authorized Range, then, as the remedy for its failure to make an
Acceptable Delivery, Lessee shall make the Rejectable Offer to Lessor in
accordance with the immediately preceding paragraph,

                                       52
<PAGE>
 
except that if Lessor timely rejects the Rejectable Offer or fails timely to
accept or reject such offer, then (1) Redelivery of the Satellite shall occur at
the end of the Lease Term pursuant to Section 10(b), and (2) as the remedy for
its failure to make an Acceptable Delivery Lessee shall pay to Lessor the
Decreased Value Payment upon the later of the Redelivery date or five (5) days
after the Decreased Value of such Transponder is determined in accordance with
the Appraisal Procedure (which procedure shall commence not later than 120 days
prior to Redelivery if the existence of a condition requiring a payment of
Decreased Value is ascertainable at such time or as soon thereafter as is
reasonably possible if it not so ascertainable). If Lessor timely accepts the
Rejectable Offer, then Lessee shall retain Control of the Transponders, and pay
the applicable Offer Amount to Lessor on the last day of the Lease Term,
together with any and all Rent due and owing; and concurrently, Lessor shall
transfer title to such Transponder to Lessee as is, where is, free and clear of
all Lessor Liens and Owner Participant Liens, but otherwise without any
warranty, by executing and delivering to Lessee an instrument substantially in
the form of Exhibit C to the Lease.

     As used herein, "Minimum Fuel Requirement" shall mean that amount of fuel
which is reasonably determined by Lessee (after consultation, if requested by
Lessor, with an appraiser who is qualified to conduct the Appraisal Procedure
and utilizing the same measurement techniques generally used by it in connection
with making such determinations) to be sufficient to cause the Satellite to have
a total useful commercial life of 15 years as measured from the Delivery Date.
As used herein, "Decreased Value" shall mean an amount equal to the decreased
value of any Transponder as of the Redelivery date due to the decrease in such
Transponder's Fair Market Sales Value

                                       53
<PAGE>
 
compared with what such value would be as of such date if the event or condition
giving rise to such decreased value had not occurred. As used herein, "Decreased
Value Payment" shall mean a payment in an amount equal to the applicable
Decreased Value.

     (e) Assumption of Certain Subleases. Upon Lessor's acceptance of a
         -------------------------------
Rejectable Offer made in respect of a Transponder pursuant to Section 10(c) or
10(d), Lessee shall assume any sublease or use agreement for the use of such
Transponder entered into by Owner Participant or Lessor (provided it has been
entered into in an arm's length transaction with a non-affiliated third party on
terms and conditions customary in the transponder leasing industry) after the
Preliminary Notice Expiration Date without such Preliminary Notice having been
delivered with respect to such Transponder and prior to the Rejectable Offer
having been made by Lessee (the "Acceptable Interim Contracts"). As a condition
to Lessee's obligation to assume any such Acceptable Interim Contract, Lessor
shall pay to Lessee any and all payments of any type it has received on account
of such Acceptable Interim Contract net of any reasonable out-of-pocket expenses
or costs incurred by Lessor or Owner Participant associated therewith.
Notwithstanding the provisions of this Section 10(e), Lessor and Owner
Participant shall not be entitled to any indemnity or reimbursement of any costs
or expenses that are not directly attributable to obtaining any Acceptable
Interim Contract or the provision of services on the related Transponder
pursuant to the Acceptable Interim Contracts. Lessee shall indemnify and hold
Owner Participant and Lessor harmless against all claims, costs or expenses
reasonably incurred in connection with an Acceptable Interim Contract, not
including any claims, costs or expenses incurred as a result of a wrongful act
by Lessor or Owner Participant. Lessor and Owner

                                       54
<PAGE>
 
Participant shall indemnify and hold harmless Lessee against all other claims, 
costs or expenses arising from any affirmative actions by Lessor or Owner 
Participant to market or otherwise utilize any such Transponder.  Lessee shall,
at the request of the Lessor or Owner Participant, furnish forms of transponder 
leases currently in use by Lessee or its Affiliates, and contracts containing 
all of the substantive provisions of such form and which are substantially 
identical in all other respects shall be deemed to comply with the requirements 
of the first sentence of this Section 10(e).

          (f)  Redelivery in Connection with Termination.  If at the time of a 
               -----------------------------------------
termination of the Lease under Section 8(a) with respect to any Transponder, or 
retention of any Transponder by Lessor in accordance with Section 8(c), such 
Transponder does not meet the requirements for an Acceptable Redelivery, Lessee 
shall pay to Lessor, in addition to the other amounts required under Section 8 
of the Lease, (A) in the case of a termination of the Lease with respect to such
Transponder pursuant to Section 8(a), the Decreased Value Payment with respect 
to such Transponder to the extent that the Fair Market Sales Value of such 
Transponder exceeds the higher of (i) the proceeds of any sale of such 
Transponder and (ii) Termination Value for such Transponder; provided that no
                                                             -------- ----
such Decreased Value Payment shall be due under this Section 8(f) if the Fair 
Market Sales Value of such Transponder is less than or equal to Termination 
Value for such Transponder, and (B) in the case of a retention of such 
Transponder by Lessor in accordance with Section 8(c), an amount equal to the 
amount, if any, by which the Fair Market Sales Value of such Transponder exceeds
the higher of (i) the fair market sales value of such Transponder and (ii) the 
Termination Value of such Transponder.

                                      55
<PAGE>
 
     SECTION 11.  Cooperation.
                  -----------

          (a)  Lessor's Efforts to Sell or Lease.  Lessee agrees that during the
               ---------------------------------                             
last 540 days of the Basic Term or any Renewal Term applicable to any
Transponder (unless Lessee has provided Lessor with the Final Notice stating
that it will renew the Lease or purchase such Transponder, pursuant to Sections
18 or 19, respectively, and in such case no Bankruptcy Default or Event of
Default shall have occurred and be continuing), it will cooperate in all
reasonable respects with efforts of Lessor to lease or sell such Transponder,
including aiding potential lessees or purchasers by providing all data relating
to maintenance and performance for inspection which Owner under the Service
Agreement and Buyer under the Purchase Agreement are entitled to receive or
inspect subject to any confidentiality requirement set forth in such agreements.
Further, Lessee shall notify existing users of such Transponder of the end of
the Lease Term and use best reasonable efforts to assist Lessor in obtaining any
necessary regulatory approvals to operate, lease or sell such Transponder, at
Lessor's reasonable cost and expense, on an After-Tax Basis to Lessee. In
addition, Lessee shall furnish to Lessor such information as it supplies to
potential lessees or purchasers of transponders that it owns or leases on the
Satellite or other similar satellites.

          (b)  Value and Useful Life Determinations.  Lessee shall provide 
               ------------------------------------
Lessor at any time with information which, in the reasonable opinion of Lessor,
is necessary or material for Lessor to negotiate and reach an agreement for any
determination of Fair Market Sales Value, Fair Market Rental Value and estimated
remaining useful commercial life; provided, however, that Lessee shall not be
                                  --------  -------                        
required to disclose

                                       56
<PAGE>
 
confidential information unrelated to the performance or maintenance of the
Transponders.

     SECTION 12.  Loss, Destruction, Condemnation or Damage.
                  -----------------------------------------

          (a)  Payment of Stipulated Loss Value.  If with respect to any 
               --------------------------------
Transponder an Event of Loss occurs, then Lessee shall forthwith (and, in any
event, within seven (7) days of such occurrence) give Lessor and Indenture
Trustee notice of such Event of Loss (the "Casualty Notice"), which notice
shall include, if applicable, Lessee's election to provide a Replacement
Transponder in accordance with the last sentence of this paragraph and shall
also state whether the proviso to this sentence shall be applicable by reason of
the Lessee having in force insurance against loss or damage to the Transponders,
pursuant to Section 9(b) or voluntarily, and on the Casualty Payment Date first
occurring not less than 30 days after the date of such notice, Lessee shall pay
to Lessor an amount equal to the sum of (x) the Stipulated Loss Value for the
Transponder due on such Casualty Payment Date and (y) the sum of (A) all amounts
of Interim Rent and Base Rent with respect to such Transponder due and unpaid
prior to such Casualty Payment Date, and (B) (i) at any time during the Interim
Term or the Basic Term, in the event that the Casualty Payment Date is a Rent
Payment Date on which a Scheduled Rent payment designated as an "arrears rent"
on Schedule A hereto as adjusted pursuant to Section 4 is due, the sum of
Scheduled Rent with respect to such Transponder designated as an "arrears rent"
on Schedule A hereto as adjusted pursuant to Section 4 and due on such Casualty
Payment Date and the Rent Differential Amount with respect to such date, if any,
or (ii) at any time during a Renewal Term any Base Rent due on such Casualty
Payment Date and (C) any other Rent with respect to such

                                      57
 
<PAGE>
 
Transponder due and unpaid as of such Casualty Payment Date; provided, however,
                                                             --------  -------
that if, with respect to such Transponder, Lessee shall have in force insurance
against loss or damage to the Transponders, pursuant to Section 9(b) or
voluntarily, then subject to the provisions of Section 12(b), Lessee shall pay
to Lessor in immediately available funds on the Casualty Payment Date first
occurring not less than thirty (30) days after the date of the Casualty Notice,
the amount specified in clause (x) of this Section less the amount of such
insurance with respect to such Transponder and, within ten (10) days after
receipt of any such insurance proceeds (but in no event later than 120 days
after the date of such Casualty Notice) the amount specified in clause (x) of
this Section to the extent not previously paid, and to the extent of any such
payment to be made from such insurance proceeds or otherwise after the Casualty
Payment Date referred to above, Lessee shall pay interest from such Casualty
Payment Date on such amount to but excluding the date of payment at the highest
interest rate payable on the Notes, if any Notes are then outstanding, and
otherwise at the Prime Rate.  In lieu of making the foregoing payment, and so
long as, but only so long as, no Bankruptcy Default or Event of Default has
occurred and is continuing, Lessee may, at its option, notify Lessor and
Indenture Trustee of its intent to, and thereafter provide Lessor (on the
Casualty Payment Date first occurring not less than thirty (30) days after the
date of the Casualty Notice) with a Replacement Transponder, in accordance with,
and subject to, the provisions and the conditions in Section 7(e); provided,
                                                                   --------
further that, in the case of an Event of Loss of the type described in clause 
- -------
(f) of the definition thereof, the amount due on the applicable Casualty Payment
Date in accordance with clause (x) of this Section 12(a) shall be the
 
                                      58
 
<PAGE>
 
higher of Stipulated Loss Value and the Fair Market Sales Value for the
Transponder on such Casualty Payment Date.  

          Upon payment in full of all amounts due or the provision of a
Replacement Transponder pursuant to the preceding paragraph, Lessor (as seller)
shall transfer the Transponder suffering such Event of Loss to Lessee, the
obligation of Lessee to pay Interim Rent and Base Rent with respect to such
Transponder shall terminate, but shall continue as to any Replacement
Transponder, such Transponder shall no longer be subject to this Lease and the
Lease Term with respect to such Transponder shall end, but shall apply to any
Replacement Transponder. 

          (b)  Application of Payments upon an Event of Loss.  Subject to the 
               ---------------------------------------------
provisions of Section 12(d), and notwithstanding any rights of Lessor as owner
of the Transponders, any payments received at any time by Lessor from any
Governmental Body or other Person as a result of the occurrence of an Event of
Loss with respect to a Transponder (including proceeds with respect to such
Transponder from insurance, if any, but excluding proceeds from Additional
Insurance with respect to such Transponder carried by Lessor, Owner Participant
or Indenture Trustee) shall be applied as follows: 

               (i) so much of such payments as shall not exceed the amount, if
     any, required to be paid with respect to such Transponder by Lessee
     pursuant to Section 12(a) shall be applied in reduction of Lessee's
     obligation to pay such amount with respect to such Transponder if not
     already paid by Lessee, or, if already paid with respect to such
     Transponder by Lessee, shall be applied to reimburse Lessee for its payment
     of such amounts, or if Lessee shall have provided Lessor with a Replacement
     Transponder pursuant to Section 12(a), shall

                                      59
 
<PAGE>
 
     be paid to Lessee upon conveyance of such Replacement Transponder to
     Lessor:

     and

               (ii)   the excess, if any, of such payments with respect to such
     Transponder remaining thereafter, shall be paid to and retained by Lessee,
     except that any such excess received in connection with an Event of Loss as
     defined in clauses (b) or (d) of the definition of Event of Loss will be
     allocated between Lessor and Lessee as their respective interests may
     appear.

          (c)  Application of Payments Not Relating to an Event of Loss.  In the
               --------------------------------------------------------
event of any loss, condemnation, confiscation, theft or seizure of, or use of,
or damage to, any portion of any Transponder not constituting an Event of Loss,
Lessee shall promptly notify Lessor and Indenture Trustee and all of Lessee's
obligations under this Lease with respect to such Transponder shall continue to
the same extent as if such event had not occurred.  Subject to the provisions of
Section 12(d), and notwithstanding any implicit or express rights of Lessor as
owner of such Transponder, payments received at any time by Lessor or Lessee
from any insurer under insurance carried by Lessee from any Governmental Body or
from any other Person with respect to any loss, condemnation, confiscation,
theft or seizure of, or use of, or damage to, any Transponder or any part
thereof not constituting an Event of Loss shall be paid to Lessor or Lessee, as
their interests may appear.

          (d)  Applications During Default.  Any amount which may become payable
               ---------------------------                                   
to Lessee pursuant to this Lease arising out of any insurance, warranty,
governmental award or otherwise shall not be paid to Lessee, or if it shall have
been paid to Lessee shall not be retained by Lessee, but shall be paid to Lessor
or Indenture
                                      60

Trustee, as the case may be, if at the time of such payment a Payment Default,
Bankruptcy Default or an Event of Default shall have occurred and be
continuing.  In such event, all such amounts shall be paid to and held by Lessor
or, to the extent required by the Indenture, Indenture Trustee, in trust as
security for the obligations of Lessee or Contractor to make payments under this
Lease and any other Operative Document or Hughes Agreement or to pay Rent
hereunder or, at the option of such holder, applied by such holder toward
payment of any such obligations of Lessee or Contractor at the time due
hereunder or under such other Operative Document or Hughes Agreement.  At such
time as there shall not be continuing a Payment Default, Bankruptcy Default or
an Event of Default all such amounts at the time held by Lessor or Indenture
Trustee, as the case may be, in excess of the amount, if any, which Lessor or
Indenture Trustee, as the case may be, shall have elected to apply as above
provided shall be paid to Lessee or Contractor, as appropriate. 

          (e)  No Duplication of Rent Differential Amount.  In the event that a
               ------------------------------------------
portion of the Scheduled Rent due on any Casualty Payment Date is designated as
an "arrears rent" on Schedule A and there is also a payment of Scheduled Rent
due on such Casualty Payment Date that is not so designated, a portion of the
Rent Differential Amount with respect to such Casualty Payment Date shall be
added to the Scheduled Rent designated as an "arrears rent" due on such date and
the remainder of such Rent Differential Amount shall be taken into account in
the computation of Stipulated Loss Value pursuant to the definition of
Stipulated Loss Value. It is intended that the entire amount of the Rent
Differential Amount due on such Casualty Payment Date shall be allocated between
the Scheduled Rent designated as an "arrears rent" due on such date

                                      61
<PAGE>
 
and the computation of Stipulated Loss Value, as appropriate and without
duplication, in such manner as will preserve the Owner Participant's Net
Economic Return and comply with the minimum payment requirement (it being
understood that the entire amount of such Rent Differential Amount shall be
taken into consideration in making such allocation).

     SECTION 13.  Merger, Consolidation.
                  ---------------------

          Neither STLC nor GMHE shall consolidate with or merge into any other
Person or convey, transfer or lease all or substantially all of its assets as an
entirety to any Person, unless:

               (i)    the successor entity formed by such consolidation or into
     which it is merged or the successor entity which acquires by conveyance,
     transfer or lease all or substantially all of its assets as an entirety
     shall be a corporation organized and existing under the laws of the United
     States of America, any State thereof or the District of Columbia which has
     a substantial part of its properties and assets located within, and
     operates substantially within, the United States of America, and which is
     qualified under the requirements of the FCC and any applicable statute,
     regulation or order to assume STLC's or GMHE's, as the case may be,
     obligations with respect to the Satellite and/or Transponders then subject
     to this Lease;

               (ii)   such successor corporation shall expressly assume in
     writing by instrument or instruments enforceable against it reasonably
     satisfactory in form and substance to Lessor and Owner Participant the due
     and punctual payment, performance and observance of all obligations of STLC
     or GMHE, as the case
                                       62
<PAGE>
 
     may be, under this Lease and any other Operative Document or Hughes
     Agreement to which STLC or GMHE, as the case may be, is a party in any
     capacity, with the same effect as if such corporation had originally been
     named Lessee herein or had been a party thereto;

               (iii)  immediately after giving effect to such transaction, no
     Bankruptcy Default or Event of Default shall exist and the Guarantee
     Agreement (or any successor agreement) shall be in full force and effect;
     and

               (iv)   STLC or GMHE, as the case may be, shall have delivered to
     Lessor, Owner Participant and Indenture Trustee an opinion of counsel in
     scope and substance reasonably satisfactory to each stating that such
     consolidation, merger, conveyance, transfer or lease and the assumption
     agreement required by clause (ii) above comply with this Section 13.

          Upon any consolidation or merger, or any conveyance, transfer or lease
of all or substantially all of the assets of STLC or GMHE, as the case may be,
as an entirety in accordance with this Section 13, the successor corporation
formed by such consolidation or into which STLC or GMHE, as the case may be, is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, Lessee under
the Operative Documents to which STLC or GMHE, as the case may be, is a party in
any capacity with the same effect as if such successor corporation had been
named Lessee herein and thereto.  No such conveyance, transfer or lease of all
or substantially all of the assets of STLC or GMHE, as the case may be, as an
entirety shall have the effect of releasing STLC or GMHE, as the case may be, or
any successor corporation which shall theretofore have become such

                                      63
<PAGE>
 
in the manner prescribed in this Section 13 from its liability hereunder or
under the other Operative Documents or Hughes Agreement to which STLC or GMHE,
as the case may be, is a party in any capacity.

     SECTION 14.  Reports.

them, Lessee shall provide or request to be provided, information regarding the
condition and state of repair of any Transponder then subject to this Lease,
compliance by Lessee with Sections 7 and 9 and performance of Seller and
Contractor under the Hughes Agreements (it being understood that information
with respect to the performance of Seller and Contractor shall be limited to
that made available pursuant to the Hughes Agreements), and the absence of any
Default, or Event of Default or Event of Loss, or event which with the passage
of time or giving of notice or both would become an Event of Loss. Indenture
Trustee shall neither have any duty to make any inquiry nor incur any liability
obligation by reason of not making any such inquiry.

          (b)  Liens.  Lessee shall promptly (and in no event later than five
               -----
(5) Business Days) notify Lessor and Indenture Trustee after having obtained
Actual Knowledge of the attachment of any Lien which Lessee shall be obligated
to discharge or eliminate pursuant to Section 6 unless the same shall already
have been removed or discharged by Lessee.

     SECTION 15. Events of Default.
                 -----------------

          Each of the following events shall constitute an Event of Default
(whether any such event shall be voluntary or involuntary or come about or be
effected by operation of law or pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation of any
Governmental Body):

such failure shall continue ten (10) Business Days after written notice thereof
by Lessor (or Indenture Trustee); or

          (c) Other than with respect to any covenant of Lessee set forth in
Section 15.02(b) of the Participation Agreement and Article X and Annex A of the
Participation Agreement, Lessee shall fail to perform or observe in any material
respect any covenant, condition or agreement to be performed or observed by it
under this Lease (other than Section 9(b)), or Guarantor shall fail to perform
or observe in any material respect any covenant, condition or agreement to be
performed or observed by it under the Participation Agreement or the Guarantee
Agreement or Lessee shall fail to perform or observe in any material respect any
other covenant, condition or agreement to be performed or observed by it under
any of the other Operative Documents to which it is a party (other than any such
covenant, condition or agreement under the Tax Indemnification Agreement not
related to the payment of money thereunder, provided

Indenture Trustee; provided, however, that if such failure is capable of cure
                   --------  -------
but cannot be cured by payment of money and cannot be cured by diligent efforts
within such 90-day period but such diligent efforts shall be properly commenced

pursue diligently, a remedy of such failure, the cure period shall be extended
for an additional period of time as may be necessary to cure, not to exceed 90
days; or
 
     (d) any representation or warranty made by STLC, GMHE or Contractor in any
of the Operative Documents or Hughes Agreements to which it is a party or in any
written statement, report, schedule, notice or other writing furnished by STLC,
GMHE or Contractor in connection therewith (other than any representation or
warranty under the Tax Indemnification Agreement) shall prove to have been
inaccurate in any material respect at the time made; provided, however, that if

the representation or warranty was originally made in good faith, an Event of
Default shall not be deemed to exist unless the inaccuracy materially adversely
affects Lessor or Owner Participant and if capable of being cured, remains
uncured for a period of ninety (90) days after receipt by Lessee of written
notice from Lessor of such inaccuracy; provided, however, that if such Default
                                       --------  -------

extended for an additional period of time as may be necessary to cure, not to
exceed 90 days; or

          (e) The Guarantee Agreement shall cease to be valid and binding or in
full force or effect; or

          (f) STLC or GMHE shall consent to the appointment of, or taking of
possession by, a receiver, trustee, custodian or liquidator of itself or of a
substantial part of its property, or shall fall to pay its debts generally as
they become due, or shall make a general assignment for the benefit of
creditors; or

     SECTION 16. Remedies.
                 --------

          Upon the occurrence of any Event of Default and at any time thereafter
so long as the same shall be continuing, Lessor may at its option declare this
Lease to be in default, and at any time thereafter Lessor may do any of the
following as Lessor in its sole discretion shall elect, to the extent permitted
by, and subject to compliance with any mandatory requirements of, Applicable Law
then in effect:

          (I) Proceed by appropriate court action, either at law or in equity,
to enforce performance by Lessee or Guarantor of the applicable covenants of
this Lease or Guarantee Agreement or to recover damages for the breach thereof;
or

          (II) By notice in writing terminate this Lease, whereupon all rights
of Lessee to the use of the Transponders shall absolutely cease and terminate
but Lessee shall remain liable as hereinafter provided;

               (a) (i) Lessor, by notice to Lessee specifying a payment date not
     later than 180 days from the date of such notice, may require Lessee to pay
     to Lessor, and Lessee hereby agrees that it will pay to Lessor, on the
     payment date specified in such notice, as liquidated damages for loss of a
     bargain, and not as a penalty, and in lieu of any further payments of
     Interim Rent or Base Rent hereunder, an amount (reduced by any amounts
     previously paid by Lessee

                                       68
<PAGE>
 
pursuant to Section 16(II)(c)) equal to the sum of (x) all unpaid Interim Rent
or Base Rent payable or which would have been payable before the Casualty
Payment Date next succeeding the date of payment specified in such notice and
(y)(A) at any time during the Interim Term or the Base Term, in the event that
the Casualty Payment Date is a Rent Payment Date on which a Scheduled Rent
designated as an "arrears rent" on Schedule A hereto as adjusted pursuant to
Section 4 is due, the sum of Scheduled Rent designated as an "arrears rent" in
Schedule A hereto as adjusted pursuant to Section 4 due on such Casualty Payment
Date with respect to the Transponders and the Rent Differential Amount, if any,
or (B) at any time during a Renewal Term, any Base Rent due on such Casualty
Payment Date and (z) an amount equal to the Stipulated Loss Value for the
Transponders calculated as of such Casualty Payment Date next succeeding the
date of payment specified in such notice (unless such payment date occurs on a
Casualty Payment Date, in which case such Stipulated Loss Value and such unpaid
Interim Rent and Base Rent shall be computed as of such Casualty Payment Date),
together with interest, if any, at the Overdue Rate on the amount of such
Interim Rent and Base Rent and Stipulated Loss Value from the date as of which
such Stipulated Loss Value is computed until the date of actual payment; and
upon such payment of liquidated damages and all other Rent then due and payable
by the Lessee hereunder, Lessor shall transfer the Transponders (without any
representation, recourse or warranty whatsoever, other than the absence of
Lessor Liens or Owner Participant Liens) to Lessee and Lessor shall execute and
deliver such documents evidencing such Transfer as Lessee shall reasonably

                                       69
<PAGE>
 
request, and Lessee shall indemnify Lessor on an After-Tax Basis for Lessor's
reasonable expenses incurred in connection with such Transfer.

     (b) Lessor or its agent may sell the Transponders at public or private
sale, as Lessor may determine, or otherwise may dispose of, hold, use, operate,
keep idle, lease (whether for a period greater or less than the balance of what
would have been the Basic Term or any Renewal Term, as the case may be) to
others the Transponders, all on such terms and conditions and at such place or
places as Lessor may determine and all free and clear of any rights of Lessee
and of any claim of Lessee, in equity, at law or by statute, whether for loss or
damage or otherwise and Lessee shall use its best efforts to obtain or assist
Lessor in obtaining, any necessary regulatory approvals for Lessor to take any
action pursuant to this Section 16(II)(b); provided, however, that (i) if Lessor
                                           --------  -------
or its agent shall sell any Transponders, Lessee's obligation to pay Interim
Rent and Base Rent with respect to any such Transponder sold hereunder for any
period after the date of such sale shall terminate and such Transponder shall
cease to be subject to this Lease from and after the date of such sale, and (ii)
Lessee's obligation to pay Interim Rent and Base Rent for any period after
Lessee shall have been deprived of control of the Transponder pursuant to clause
(i) of this Section 16(II)(b) shall be reduced by the net proceeds, if any,
received by Lessor from leasing the Transponder to, or otherwise permitting its
use by, any Person other than Lessee fairly attributable to all or any portion
of such period. In the event Lessor shall have sold any Transponder pursuant to
this Section 16(II)(b) (and prior thereto shall not have exercised its rights
under Section 16(II)(c)

                                       70
<PAGE>
 
hereof), Lessor may demand that Lessee pay Lessor and Lessee shall pay to
Lessor, as liquidated damages for the loss of a bargain and not as a penalty, in
lieu of all Interim Rent or Base Rent due after the date on which such sale
occurs, an amount equal to the sum of (i) all unpaid Interim Rent and Base Rent
payable or which would have been payable on or before the Casualty Payment Date
next succeeding the date on which the sale occurs (unless such sale occurs on a
Casualty Payment Date, in which case Interim Rent or Base Rent shall be computed
as of such Casualty Payment Date) plus (ii) the amount, if any, by which the
Stipulated Loss Value for such Transponder, computed as of the Casualty Payment
Date immediately following the date on which such sale occurs (unless such sale
occurs on a Casualty Payment Date, in which case as of such Casualty Payment
Date), exceeds the net proceeds of such sale (together with interest, if any, at
the Overdue Rate on the amount of such Interim Rent and Base Rent and deficiency
from the Casualty Payment Date as of which such Stipulated Loss Value is
computed until the date of actual payment).

     (c) Whether or not Lessor shall have exercised, or shall thereafter at any
time exercise, any of its rights under Section 16(II)(b) hereof (other than a
sale under Section 16(II)(b) hereof), Lessor may, at any time prior to the time
that any Transponder shall have been sold or leased by Lessor pursuant to
Sections 16(II)(a) or 16(II)(b) hereof, by written notice to Lessee requesting
that the fair market sales value or fair market rental value of such Transponder
be determined, demand that Lessee pay to Lessor, and Lessee shall pay to Lessor
on the first Casualty Payment Date occurring at least ten (10) days

                                       71

after the determination of such fair market sales value or fair market rental
value, each determined on an as is, where is basis, as the case may be, as
liquidated damages for loss of a bargain and not as a penalty (in lieu of all
payments of Interim Rent and Base Rent with respect to such Transponder becoming
due for periods after the payment date), an amount equal to the sum of (i) all
unpaid Interim Rent and Base Rent due before such Casualty Payment Date and
(ii)(A) at any time during the Interim Term or the Basic Term, in the event that
the Casualty Payment Date is a Rent Payment Date on which a Scheduled Rent
designated as an "arrears rent" on Schedule A hereto as adjusted pursuant to
Section 4 is due, the sum of Scheduled Rent designated as an "arrears rent" in
Schedule A hereto as adjusted pursuant to Section 4 due on such Casualty Payment
Date with respect to such Transponder and the Rent Differential Amount, if any,
or (B) at any time during a Renewal Term, any Base Rent due on such Casualty
Payment Date, and (iii) whichever of the following amounts Lessor, in its sole
discretion, shall specify in such notice (together with interest on such amount
at the Overdue Rate from the scheduled payment date to the date of actual
payment): (x) an amount equal to the excess, if any, of the Stipulated Loss
Value, computed as of such Casualty Payment Date, over the fair market rental
value for such Transponder, valued on an as is, where is basis for the remainder
of the Interim Term and the Basic Term or the remainder of the Renewal Term, as
the case may be, after discounting such fair market rental value semi-annually
(effective on the Rent Payment Dates) to present value as of the scheduled
payment date at the rate of interest equal to the Overdue Rate; (y) an amount

                                       72
<PAGE>
 
equal to the excess, if any, of such Stipulated Loss Value as of such Casualty
Payment Date over the fair market sales value of such Transponder valued on an
as is, where is basis or (z) an amount equal to the excess, if any, of (A) the
present value computed as of such Casualty Payment Date of all installments of
Scheduled Rent for the remainder of the Interim Term and Basic Term or Base Rent
for the remainder of the Renewal Term, as the case may be, discounted semi-
annually (effective on the Rent Payment Dates) to present value as of the
scheduled payment date at the rate of interest equal to the Overdue Rate over
(B) the present value, computed as of such Casualty payment Date, of the fair
market rental value of the Transponder for the remainder of the Interim Term and
the Basic Term or of the Renewal Term, as the case may be, discounted semi-
annually (effective on the Rent Payment Dates) to present value as of the
scheduled payment date at the rate of interest equal to the Overdue Rate.

     (d) For all purposes of this Section 16, in the event that a portion of the
Scheduled Rent due on any Casualty Payment Date is designated as an "arrears
rent" on Schedule A and there is also a payment of Scheduled Rent due on such
Casualty Payment Date that is not so designated, a portion of the Rent
Differential Amount with respect to such Casualty Payment Date shall be added to
the Scheduled Rent designated as an "arrears rent" due on such date and the
remainder of such Rent Differential Amount shall be taken into account in the
computation of Stipulated Loss Value pursuant to the definition of Stipulated
Loss Value. It is intended that the entire amount of the Rent Differential
Amount due on such Casualty Payment Date shall be allocated between the

                                       73
<PAGE>
 
    Scheduled Rent designated as an "arrears rent" due on such date and the
    computation of Stipulated Loss Value, as appropriate and without
    duplication, in such manner as will preserve the Owner Participant's Net
    Economic Return and comply with the minimum payment requirement (it being
    understood that the entire amount of such Rent Differential Amount shall be
    taken into consideration in making such allocation).

All determinations of fair market sales value and fair market rental value
pursuant to this Section 16 shall be determined pursuant to the Appraisal
Procedure. No termination of this Lease, in whole or in part, or exercise of any
remedy under this Section 16 shall, except as specifically provided herein,
relieve Lessee of any of its liabilities and obligations hereunder, all of which
shall survive such termination, repossession or exercise of remedy. In addition,
Lessee shall be liable for any and all unpaid Supplemental Rent due hereunder
before, after or during the exercise of any of the foregoing remedies, including
all reasonable legal fees and other costs and expenses reasonably incurred by
Lessor, Owner Participant or Indenture Trustee by reason of the occurrence of
any Event of Default or the exercise of Lessor's remedies with respect thereto.
At any sale of the Transponders or any part thereof pursuant to this Section 16,
Lessor, Owner Participant or Indenture Trustee may bid for and purchase such
property.

     Notwithstanding any provision in this Lease or any other Operative
Document, Lessee shall not cease to have the legal right to access any of the
Transponders unless and until Lessor shall give Lessee and Seller, at the time
when a notice of termination is given under the first sentence of clause (II)
above, 24 hours notice expressly demanding that Lessee surrender such right.

     To the extent permitted by, and subject to the mandatory requirements of,
Applicable Law, and except as otherwise specifically provided for in this Lease,
each and every right, power and remedy herein specifically given to Lessor or
otherwise in this Lease shall be cumulative and shall be in addition to every
other right, power and remedy herein specifically given or now or hereafter
existing at law, in equity or by statute, and each and every right, power and
remedy whether specifically herein given or otherwise existing may be exercised
from time to time and as often and in such order as may be deemed expedient by
Lessor, and the exercise or the beginning of the exercise of any power or remedy
shall not be construed to be a waiver of the right to exercise at the same time
or thereafter any other right, power or remedy. No delay or omission by Lessor
in the exercise of any right, remedy or power or in the pursuit of any remedy
shall impair any such right, remedy or power or be construed to be a waiver of
any default on the part of Lessee or to be an acquiescence therein. No express
or implied waiver by Lessor of any Event of Default shall in any way be, or be
construed to be, a waiver of any future or subsequent Event of Default.

     Except to the extent provided for by the express terms of this Lease, each
of Lessor and Indenture Trustee and any Person claiming through either of them,
waives and agrees not to claim any amount under this Section 16 or otherwise
under this Lease in respect of incidental or consequential damages incurred by
it.

     To the extent permitted by Applicable Laws, Lessee hereby waives any rights
now or hereafter conferred by statute or otherwise that may require Lessor, its
successors or assigns to mitigate its damages in any particular manner or that
may otherwise limit or modify any of the rights or remedies of Lessor under this
Section 16,

                                       75
<PAGE>
 
but nothing contained herein shall eliminate Lessor's obligation to mitigate its
damages as may be required by Applicable Law.

   SECTION 17. Right to Perform for Lessee.
               ---------------------------

     (a) Right to Cure. If Lessee shall fail to make any payment of Rent to be
         -------------
made by it hereunder or shall fail to perform or comply with any of its other
agreements contained herein or in the Hughes Agreements relating to any of the
Transponders, Lessor or Owner Participant may (but shall not have any duty to do
so) itself make such payment or perform or comply with such agreement; provided
                                                                       --------
that nothing contained in this Section 17(a) shall be deemed to expand in any
- ----
way the rights of Owner Trustee or Owner Participant under Section 16.1 of the
Indenture. The amount of any such payment and the amount of the reasonable
expenses of Lessor and Owner Participant incurred in connection with such
payment or the performance of or compliance with such agreement, as the case may
be, together with interest thereon at the Overdue Rate, shall be deemed
Supplemental Rent, payable by Lessee upon demand.

     (b) Lessor is Lessee's Agent and Attorney. Without in any way limiting the
         -------------------------------------
obligations of the Lessee or Lessor, hereunder, Lessee hereby irrevocably
appoints Lessor as its agent and attorney-in-fact hereunder, with full power and
authority at any time at which Lessee is obligated to deliver any Transponder to
Lessor, to demand and take such Transponder in the name and on behalf of Lessee
from whomsoever shall be at the time in control thereof.

     SECTION 18. Renewal.
                 -------

          (a) Notice of Renewal or Purchase. Except as otherwise specifically
              -----------------------------
provided in Section 18(d), not more than 720 nor less than 540 days prior to the
expiration of the Basic Term or the First Renewal Term, as the case may be, but
in no event before Lessee shall have received the Subsequent Appraisal (provided
Lessee ordered it as provided in Section 20(d), below) (the "Preliminary Notice
                                                             ------------------
Expiration Date"), Lessee shall give Lessor notice (the "Preliminary Notice")
- ---------------                                          ------------------
of Lessee's irrevocable intention to (i) renew the Lease pursuant to Section
18(b) in respect of any Selected Transponder and/or all but not less than all
Remaining Transponders; (ii) purchase any Selected Transponder and/or all but
not less than all Remaining Transponders pursuant to Section 19(a)(i).

          If, during the Basic Term, Lessee timely provides the Preliminary
Notice, then not later than 270 days prior to the expiration of the Basic Term,
Lessor shall provide Lessee with written notice specifying whether Lessee's
renewal right under Section 18(b) with respect to any such Transponder shall be
for (A) the Single Renewal Term or (B) for two Renewal Terms (i.e., a First
Renewal Term and a Second Renewal Term) (the "Renewal Term Notice"), provided
                                              -------------------
that if such Renewal Term Notice is not timely given by Lessor, then such notice
shall be deemed to have been given by Lessor and to have specified two Renewal
Terms.

          With respect to any Selected Transponder, Lessee shall, as an
additional condition to giving the Preliminary Notice and concurrently
therewith, deliver to Lessor a certificate from the chief executive, chief
financial or chief operating officer of STLC stating that:

                                       77
<PAGE>
 
     (1) the Transponder as to which such Preliminary Notice has been given is
the subject of a Use Agreement or Existing Agreement which, by its terms, may be
extended by the User or Sublessee beyond the Lease Term (the "Extension Right");
and

     (2) such right of the User or Sublessee has either been exercised, or is
presently in effect and has not been waived by such User or Sublessee; and

     (3) the Extension Right was not given to such User or Sublessee for the
primary purpose of enabling the Lessee to meet the conditions necessary to have
the Transponder treated as a Selected Transponder.

     If Lessee gives the Preliminary Notice, then (except as provided in Section
18(d)) not less than (180) days before the expiration of the Basic Term or the
First Renewal Term, as applicable (the "Final Notice Expiration Date"), Lessee
                                        ----------------------------
shall give Lessor notice of its irrevocable election (the "Final Notice") of one
                                                           ------------
of the following options: (i) to renew this Lease pursuant to Section 18(b) for
any Selected Transponder and/or all Remaining Transponders identified in the
Preliminary Notice (A) for a Single Renewal Term, if applicable, or (B) for the
First Renewal Term or Second Renewal Term as applicable, or (ii) to purchase
any Selected Transponder and/or all Remaining Transponders identified in the
Preliminary Notice pursuant to Section 19(a)(i).

     If Lessee shall fail timely to deliver the Preliminary Notice, then, except
as provided in Section 18(d), Lessee shall be deemed not to have elected to
renew this Lease or purchase any Transponder, and promptly thereafter, but in
any case within 30 days after the Preliminary Notice Expiration Date, shall
provide Lessor with the names, last known business addresses and telephone
numbers of the Persons using any Transponders pursuant to a Use Agreement (not
including any Occasional Use Service

                                       78
<PAGE>
 
Contract) or an Existing Lease. If Lessee shall fail to deliver the Final
Notice as required above after having delivered the Preliminary Notice, Lessee
shall be deemed to have elected to purchase the Transponders identified in such
Preliminary Notice pursuant to Section 19(a)(i) hereof. The notice requirements
of this Section 18(a) shall not apply to Lessee's right to purchase any
Transponders pursuant to Sections 19(a)(ii) and (iii). As used herein,
"Remaining Transponder" shall mean any Transponder, subject to the Lease, which
is not a Selected Transponder.

     (b) Fair Market Value Renewal Option. If Lessee delivers the Final Notice
         --------------------------------
set forth in Section 18(a), above, stating that it will renew the Lease in
respect of the Transponders identified in such Final Notice, and so long as no
Bankruptcy Default or Event of Default has occurred and is continuing at the end
of the Basic Term or, if applicable, the First Renewal Term, then this Lease
shall be renewed with respect to such Transponders at a Base Rent equal to the
Fair Market Rental Value of such Transponders (as determined pursuant to the
most recent Subsequent Appraisal) and payable in accordance with Section 18(c),
below. The Renewal Term shall be for the following period: (i) in the event
Lessor has specified a Single Renewal Term option in the Renewal Term Notice,
then the term shall begin immediately upon the expiration of the Basic Term and,
unless earlier terminated pursuant to the terms of this Agreement, shall end on
the last day of the useful commercial life of the Satellite (as determined
pursuant to the most recent Subsequent Appraisal) or on the date the Satellite
is disposed of pursuant to Section 13 of the Purchase Agreement or (ii) in the
event Lessor has specified two Renewal Terms in the Renewal Term Notice, then
the term shall begin immediately upon expiration of the Basic Term and, unless
earlier terminated pursuant 
 

                                       79
<PAGE>
 
to the terms of this Agreement, shall end on the day prior to the last day of
the period of time which is equal to 80% of the remaining useful commercial life
of the Satellite (as determined pursuant to the Subsequent Appraisal) measured
from the commencement of such term (the "First Renewal Term"). If Lessee
                                         ------------------
renews the Lease for a First Renewal Term, and provided no Bankruptcy Default or
Event of Default has occurred and is continuing at the end of the First Renewal
Term, Lessee may renew the Lease (pursuant to the procedure set forth in Section
18(a), above) for a second renewal term, on terms identical to the First Renewal
Term as set forth in the immediately preceding sentence, except only that such
second renewal term shall begin immediately upon the expiration of the First
Renewal Term and, unless earlier terminated pursuant to the terms of this
Agreement, shall end on the last day of the useful commercial life of the
Satellite (as determined pursuant to the most recent Subsequent Appraisal) or on
the date the Satellite is disposed of pursuant to Section 13 of the Purchase
Agreement (the "Second Renewal Term"). At the end of the Basic Term or First
                -------------------
Renewal Term, as applicable, if Lessee has timely elected to renew this Lease
with respect to any Transponder, then the terms and conditions of this Lease
with respect to such Transponder shall continue in full force and effect during
the following Renewal Term, except that (x) Lessee shall pay Lessor Base Rent
for such Transponder in the amount of the Fair Market Rental Value thereof as
determined by the most recent Subsequent Appraisal and (y) the Stipulated Loss
Values and Termination Values applicable during such Renewal Term shall
initially be the Fair Market Sales Value (determined pursuant to such Subsequent
Appraisal) of such Transponder as of the commencement of the Renewal Term and,
on each Casualty Payment Date during the Renewal Term, shall decline on a
straight line basis by an
 

                                       80
<PAGE>
 
amount per Casualty Payment Date obtained by dividing (iii) the difference
between the Fair Market Sales Value of such Transponder as of the beginning of
such Renewal Term and the estimated Fair Market Sales Value of such Transponder
as of the end of such Renewal Term by (iv) the number of months in such Renewal
Term.

     (c) Renewal Rents. At the end of the Basic Term or the First Renewal Term,
         -------------
as the case may be, if Lessee shall have timely elected to renew this Lease as
aforesaid and if no Bankruptcy Default or Event of Default shall then exist and
be continuing, Lessee and Lessor shall execute a Lease Supplement hereto in form
and substance reasonably satisfactory to Lessor and Lessee to evidence such
renewal. Such Lease Supplement shall provide for the semi-annual (or shorter
period if necessary in case of the last Lease Period) payment of Base Rent for
the Renewal Term, with a final installment on the last day of any such Renewal
Term, payable in each case in arrears, in accordance with the aforesaid
determinations of Base Rent and shall provide for Stipulated Loss and
Termination Values for the Transponders covered thereby with respect to such
Renewal Term determined as aforesaid. The installments of Base Rent during the
Renewal Term shall be equal in amount (except for the last such installment
which shall be pro rated, if necessary, for a Lease Period which is shorter than
six months). All other terms of this Lease, the Guarantee Agreement and the
Participation Agreement, as applicable, shall continue in effect during each
such Renewal Term in accordance with the provisions hereof and thereof, except
as otherwise expressly provided in the Lease.

     (d) Extended Notice. If with respect to any Transponder subject to an
         ---------------
Existing Lease or Use Agreement (the "Subleased Transponder(s)"), Lessee has not

                                       81
<PAGE>
 
timely provided the Preliminary Notice, and if following the Preliminary Notice
Expiration Date but on or prior to the end of the Lease Term, the sublessee or
User under such Existing Lease or Use Agreement exercises its renewal rights
thereunder, then Lessee shall be entitled to give the Final Notice with respect
to such Subleased Transponder, such notice to be provided on or before the end
of the Lease Term; provided, however, that Lessee shall not be entitled to
                   --------  -------
exercise the foregoing rights with respect to such Subleased Transponder if
during the period from the Preliminary Notice Expiration Date and prior to
Lessee's delivery of the Final Notice, Lessor has executed a valid and binding
agreement for the purchase, lease or use of such Subleased Transponder with a
third party that is not an Affiliate. During the period between the Preliminary
Notice Expiration Date and the end of the Lease Term, Lessor shall promptly
provide Lessee with written notice of the consummation of any such agreement
with respect to any Subleased Transponder as to which Lessee has not timely
provided the Preliminary Notice.

   SECTION 19. Purchase Options.
               ----------------

     (a) Purchase Option Events. So long as no Bankruptcy Default or any Event
         ----------------------
of Default has occurred and is continuing, Lessee shall have the right to
purchase:

          (i) if Lessee timely delivers or is deemed to have delivered the Final
Notice contemplated by Section 18(a)(ii) or 18(d) (stating that it will purchase
the Transponders identified in such Final Notice), such Transponders on the
expiration date of the Lease Term or the First Renewal Term, as applicable, at a
purchase price equal to the Fair Market Sales Value of such Transponders as of
such date as determined pursuant to the most recent Subsequent Appraisal;

                                       82
<PAGE>
 
         (ii) all (but not less than all) of the Transponders (A) on the First
EBO Date at a purchase price equal to the First EBO Amount therefor or (B) on
the Second EBO Date at a purchase price equal to the greater of (x) the Second
EBO Amount therefor and (y) the Fair Market Sales Value of such Transponders as
of such date as determined by an appraisal obtained in accordance with Section
19(b)(i); and

         (iii) if Owner Participant has become a Competitor and fails to
transfer all of its right, title and interest in and to the Lessor's Estate and
the Operative Documents in accordance with Article XIII of the Participation
Agreement within three (3) months after the Owner Participant has become a
Competitor, all (but not less than all) of the Transponders on any Rent Payment
Date, at a purchase price equal to the greater of (A) the Termination Value for
such Transponders as of such Rent Payment Date and (B) the Fair Market Sales
Value of such Transponders as of such Rent Payment Date.

         (b) Notice of Election; Manner of Purchase; Transfer After Purchase.
             ---------------------------------------------------------------

             (i) In order to exercise its right to purchase the Transponders
pursuant to Section 19(a)(ii)(A), Lessee shall, at least ninety (90) days prior
to the First EBO Date referred to in Section 19(a)(ii)(A), give irrevocable
notice to Lessor in writing stating that Lessee will purchase such Transponder
pursuant to Section 19(a)(ii)(A). In order to exercise its right to purchase all
of the Transponders pursuant to Section 19(a)(ii)(B), Lessee shall give
tentative notice to Lessor in writing at least 145 days prior to the Second EBO
Date that it desires to obtain an appraisal of the Fair Market Sales Value of
the Transponders as of the Second EBO Date. Such Fair Market Sales Value shall
be determined pursuant to the Appraisal Procedure (provided

 
                                       83
<PAGE>
 
that the timetable for the Appraisal Procedure shall be appropriately
accelerated to meet the deadlines set forth in this paragraph 19(b)(i), so long
as notwithstanding such acceleration, the appraiser shall have adequate time to
make a considered determination). Lessee shall give irrevocable notice to Lessor
on the later to occur of (1) five (5) days after completion of the Appraisal
Procedure or (2) ninety (90) days prior to the Second EBO Date (but in no event
later than sixty (60) days prior to the Second EBO Date), if it desires to
consummate the purchase of the Transponders pursuant to Section 19(a)(ii)(B).

     (ii) In order to exercise its right to purchase all of the Transponders
pursuant to Section 19(a)(iii), Lessee shall give tentative notice to Lessor in
writing within 90 days after (A) Owner Participant shall have confirmed to
Lessee pursuant to Section 5.02(i) of the Participation Agreement that it is a
Competitor, or (B) Lessee shall have notified Owner Participant that Owner
Participant has become a Competitor, and Owner Participant shall have become a
Competitor, whichever of (A) or (B) shall first occur, that it desires to obtain
an appraisal of the Fair Market Sales Value of the Transponders as of the Rent
Payment Date specified in the notice given by Lessee under this Section
19(b)(ii). Promptly after Lessee shall have given such notice, such Fair Market
Sales Value shall be determined pursuant to the Appraisal Procedure (provided
that the timetable for the Appraisal Procedure shall be appropriately
accelerated to meet the deadlines set forth in the next sentence, so long as
notwithstanding such acceleration, the appraiser shall have adequate time to
make a considered determination). Lessee shall give irrevocable notice to Lessor
not later than ten Business Days after the completion of the Appraisal Procedure
if it desires to

                                       84
<PAGE>
 
consummate the purchase of the Transponders pursuant to Section 19(a)(iii) but
in no event later than fifteen (15) days prior to the Rent Payment Date
specified in the notice referred to in this Section 19(b)(ii), which Rent
Payment Date shall be the next succeeding Rent Payment Date no earlier than 30
days following the date of such notice.

     (iii) On the date of purchase, Lessee shall pay the purchase price for
such Transponders, together with (A) all Interim Rent and Base Rent due and
unpaid prior to the date of such purchase and (B)(i) at any time during the
Basic Term, in the event that the date of purchase is a Rent Payment Date on
which a Scheduled Rent payment designated as an "arrears rent" on Schedule A
hereto as adjusted pursuant to Section 4 is due, any Scheduled Rent designated
as an "arrears rent" on Schedule A as adjusted pursuant to Section 4 due on such
date of purchase with respect to such Transponders and the Rent Differential
Amount, if any, or (ii) at any time during a Renewal Term, any Base Rent due on
such date and (C) any other Rent (including Premium, if any, on the outstanding
Notes) due and unpaid as of the date of such purchase. Upon receipt of the
payments set forth in the preceding sentence, Lessor shall transfer all right,
title and interest of Lessor in and to the Transponders, as is and where is, to
Lessee, free and clear of Lessor Liens and Owner Participant Liens, but
otherwise without warranty, and Lessor shall execute and deliver to Lessee, at
Lessee's reasonable expense, a bill of sale or assignment and such other
instruments, documents and opinions as Lessee may reasonably request to evidence
the valid consummation of such Transfer and shall take such actions under
Section 10 of the Indenture as Lessee may reasonably request.
 

                                       85
<PAGE>
 
     (c) Assumption of Notes. Notwithstanding the provisions of Sections 19(a)
         -------------------
and (b) and subject to compliance with Section 2.13 of the Indenture, if in
connection with a purchase by Lessee of the Transponders pursuant to Section
19(a)(ii) or Section 19(a)(iii) as the case may be, Lessee shall assume the
Notes pursuant to Section 5.05(a) or Article XI of the Participation Agreement,
the obligation of Lessee to pay the purchase price pursuant to Section 19(a)(ii)
or 19(a)(iii), as the case may be, shall be satisfied by such assumption of the
Notes to the extent of the principal amount of the Notes so assumed (after, in
the event that the date of purchase is a Rent Payment Date on which a Scheduled
Rent payment designated as an "arrears rent" on Schedule A hereto as adjusted
pursuant to Section 4 is due, payment of the sum of any Scheduled Rent
designated as an "arrears rent" on Schedule A as adjusted pursuant to Section 4
on the Rent Payment Date on which such purchase is consummated with respect to
such Transponders and the Rent Differential Amount, if any).

     (d) No Duplication of Rent Differential Amount. In the event that a 
         ------------------------------------------
portion of the Scheduled Rent due on any date of purchase is designated as an
"arrears rent" on Schedule A and there is also a payment of Scheduled Rent due
on such date of purchase that is not so designated, a portion of the Rent
Differential Amount with respect to such date of purchase shall be added to the
Scheduled Rent designated as an "arrears rent" due on such date and the
remainder of such Rent Differential Amount shall be taken into account in the
computation of the EBO Amount pursuant to the definition of First EBO Amount or
Second EBO Amount or the computation of Termination Value, as appropriate. It is
intended that the entire amount of the Rent Differential Amount due on such date
of purchase shall be allocated between the
 

                                       86
<PAGE>
 
Scheduled Rent designated as an "arrears rent" due on such date and the
computation of the applicable EBO Amount or the Termination Value, as
appropriate and without duplication, in such manner as will preserve the Owner
Participant's Net Economic Return and comply with the minimum payment
requirement (it being understood that the entire amount of such Rent
Differential Amount shall be taken into consideration in making such
allocation).

   SECTION 20. Further Assurances; Default Notice; Subsequent Purchase Option.
               --------------------------------------------------------------

     (a) Further Assurances. Lessee, at its reasonable expense, shall promptly
         ------------------
and duly execute and deliver to Lessor, Owner Participant and Indenture Trustee
such documents and assurances and take such further action as Lessor (and
Indenture Trustee) may from time to time reasonably request in order to carry
out more effectively the intent and purpose of this Lease, the other Operative
Documents and the Hughes Agreements and to establish and protect the rights and
remedies created or intended to be created in favor of Lessor hereunder and
thereunder, to establish, perfect (to the extent practicable, in the case of the
Transponders), and maintain Lessor's right, title and interest in and to the
Transponders and the Indenture Estate and, for the benefit of Indenture Trustee,
the lien and security interest in the Indenture Estate provided for in the
Indenture, subject to no Lien other than Permitted Liens, including, without
limitation, if requested by Lessor, Owner Participant or Indenture Trustee, at
the expense of Lessee, the recording or filing of appropriate memoranda hereof,
or of such financing statements or other documents with respect hereto as any of
Lessor, Owner Participant or Indenture Trustee may from time to time reasonably
request, and Lessor agrees promptly to execute and deliver such of the foregoing
financing statements or

                                       87
<PAGE>
 
other documents as may require execution by Lessor and to the extent permitted
by Applicable Laws, Lessee hereby authorizes any such financing statements to be
filed without the necessity of signature by Lessee; provided, however, no
                                                    --------  -------
counterparts hereof shall be filed, unless Lessor or Indenture Trustee shall
determine that it is advisable, in the reasonable opinion of the counsel of
Lessor or Indenture Trustee, as the case may be, to file such counterpart in
order to protect its interest under this Lease; then, upon 30 days' prior notice
and delivery to Lessee of such opinion of counsel of Lessor or Indenture
Trustee, as the case may be, Lessor or Indenture Trustee, as the case may be,
may file such counterpart.

     (b) Notice of Default. Promptly after obtaining Actual Knowledge of the
         -----------------
occurrence or existence of any Default or Event of Default, Lessee shall so
notify Lessor (and Indenture Trustee) and set forth in reasonable detail the
circumstances surrounding such Default or Event of Default and shall specify
what actions Lessee has taken or intends to take to cure such Default or Event
of Default.

     (c) Subsequent Purchase Option.
         --------------------------

         (i) Right to Purchase Option. So long as, but only so long as,
             ------------------------
no Bankruptcy Default or any Event of Default shall have occurred and is
continuing, on the expiration of the Lease Term, Lessee shall have the Right to
purchase an option (the "Subsequent Purchase Option") at a purchase price (the
                         --------------------------
"Option Price") determined as set forth below, on the terms and conditions set
- ---------------
forth in Section 20(c)(ii). The Subsequent Purchase Option shall give Lessee the
right, at any time after the expiration of the Lease Term, upon exercise by
Lessee of the option (the "Subsequent Option Exercise Notice"), to purchase and
                           ---------------------------------
to exercise immediate Control over, pending
 

                                       88
<PAGE>
 
completion of purchase, all (but not less than all) of the Transponders which
are then owned by Lessor, if Lessee determines, in its sole discretion, that
such purchase will enable Lessee to fulfill its then existing commitments to
transponder purchasers, transponder lessees or other users of transponder
capacity on Hughes satellites. Lessee shall also have the right, pursuant to the
Subsequent Purchase Option, which Lessee may, subject to obtaining any required
FCC approvals, exercise at any time concurrently with or after giving the
Subsequent Option Exercise Notice, to move the Satellite without restriction by
Lessor or any other Person.

     (ii) Creation of Subsequent Purchase Option. In order to be able to
          --------------------------------------
purchase the Subsequent Purchase Option, Lessee shall give the Lessor
irrevocable notice, not earlier than 720 days nor later than 540 days prior to
the expiration of the Basic Term or expiration of the First Renewal Term, as
applicable, but in no event before the Lessee shall have received the Subsequent
Appraisal (provided it shall have been ordered pursuant to Section 20(d) (the
"Subsequent Purchase Option Cut-off Date")), that it shall purchase the
Subsequent Purchase Option unless it purchases the related Transponder or renews
the Lease with respect thereto. The Subsequent Appraisal shall be ordered by
Lessee to determine the Pre-emptibility Cost. Failure timely to give such notice
shall constitute an irrevocable waiver of the rights of Lessee under this
Section 20(c). As used herein, "Pre-emptibility Cost" shall mean the diminution
in the Fair Market Sales Value, as of the end of the Basic Term or the First
Renewal Term, as applicable, that would be caused to the Transponders as a
result of the issuance to Lessee of the Subsequent Purchase Option, which option
will make the Transponders pre-emptible during the period such Subsequent
Purchase Option is in

                                       89
<PAGE>
 
effect. The Option Price per Transponder shall be equal to the higher of the 
Pre-emptibility Cost and seven percent of Buyer's Cost for such Transponder.
Lessee shall pay the Option Price to Lessor, by wire transfer of immediately
available funds upon expiration of the Basic Term or the First Renewal Term, as
applicable, and such Option Price shall be payable for any Transponder Lessee
has not previously purchased from Lessor as of the expiration of the Lease Term.

         (iii) The Subsequent Purchase Price. The Subsequent Purchase Option 
               -----------------------------
shall give Lessee the right to purchase the Transponders, at any time, with
respect to all (but not less than all) of the Transponders then owned by Lessor
for a price equal to the then Fair Market Sales Value of the Transponders at the
orbital slot at which the Satellite is then located prior to any move of the
Satellite referred to in Section 20(c)(i), and based on the assumption that each
of Seller or Contractor (or Substitute Service Provider, if applicable) is in
compliance with its obligations under the Hughes Agreements (or the Substitute
Service Agreement, if applicable) and taking into account the pre-emptible
nature of such Transponders.

          (iv) Option Exercise. The Subsequent Purchase Option shall be
               ---------------
exercised by giving the Subsequent Option Exercise Notice. The Subsequent Option
Exercise Notice may be given by facsimile or by personal delivery of written
notice, and in each such case it shall be effective immediately upon receipt.
Notice may also be given by any other means provided for in Section 23 hereof or
in Section 15.03 of the Participation Agreement.

          (v) Survival; Provisions In Other Contracts. Lessor agrees that its
              ---------------------------------------
obligations under this Section 20(c) shall, as to each Transponder, survive the
 

                                       90
<PAGE>
 
termination of this Lease. Lessor agrees that it will, as part of any Transfer
of its rights to any Transponder, including, without limitation, a Transfer to
the Owner Participant, notify its Transferee of the provisions of this Section
20(c) and obtain a written acknowledgment and agreement from such Transferee (in
the form attached as Exhibit D) to immediately relinquish its use of any such
Transponder upon Lessee's exercise of its Subsequent Purchase Option as set
forth in this Section 20(c).

     (d) Subsequent Appraisal. No earlier than 760 days and no later than 720
         --------------------
days prior to the end of the Basic Term, as applicable, Lessee shall have the
option to initiate the Appraisal Procedure, and at Lessee's cost and expense, to
perform an appraisal of the Transponders to determine, as appropriate, the
remaining useful commercial life, residual value and the Pre-emptibility Cost,
and the Fair Market Sales Value and Fair Market Rental Value of the Transponders
as of the end of such Basic Term or the First Renewal Term, as applicable (the
"Subsequent Appraisal").

   SECTION 21. Indenture Estate as Security for Lessor's Obligations to
               --------------------------------------------------------
Indenture Trustee.
- -----------------
   
     (a) In order to secure the indebtedness evidenced by the Notes and all
obligations secured by the Indenture, Lessor provides in the Indenture, among
other things, for the assignment (to the extent provided therein) by Lessor to
Indenture Trustee of all of Lessor's right, title and interest to this Lease and
for the creation of a Lien and security interest in favor of Indenture Trustee
for the benefit of the Noteholder in and to the Indenture Estate as described in
the granting clauses of the Indenture. Lessee hereby (a) consents to such
assignment pursuant to the terms of the Indenture, and (b) agrees to pay
directly to Indenture Trustee for so long as the Lien of the

                                       91
<PAGE>
 
Indenture shall remain in effect and thereafter to Lessor, all amounts (other
than Excepted Payments) due and to become due to or for the account of Lessor
and payable by Lessee hereunder or under any other Operative Document or Hughes
Agreement to which Lessee in any capacity is a party which have been assigned or
required to be assigned to Indenture Trustee pursuant to the Indenture or this
Agreement. Lessee acknowledges that, so long as any Notes are outstanding, all
rights of Lessor under this Lease shall be exercised only by the Indenture
Trustee, as assignee of Lessor's rights under this Lease pursuant to the
Indenture, subject, however, to Sections 9.2, 13.1 and 16.4 of the Indenture and
subject to Lessor's rights in respect of Expected Payments.

          (b) Notwithstanding anything to the contrary hereinabove, Indenture
Trustee shall not have any greater rights under the Hughes Agreements than
Lessor shall have pursuant to Section 5(b)(ii) and (iii) of this Agreement or
than the Lessor otherwise has under this Lease.

   SECTION 22. Counterparts; Uniform Commercial Code.
               -------------------------------------

     This Lease and each Lease Supplement may be executed by the parties hereto
in separate counterparts, each of which when so executed and delivered shall be
an original, but all such counterparts shall together constitute but one and the
same instrument. To the extent, if any, that this Lease constitutes chattel
paper (as such term is defined in the Uniform Commercial Code as in effect in
any applicable jurisdiction), no security interest in this Lease may be created
through the transfer or possession of any counterpart hereof other than the
original executed counterpart which shall be identified as the counterpart
containing the receipt therefor executed by Indenture Trustee on the signature
page thereof.

   SECTION 24. Miscellaneous.
               -------------

     (a) Severability. Any provision of this Lease which is prohibited or
         ------------
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof or of any provision in any other Operative Document
or Hughes Agreement, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. The provisions of this Lease shall remain valid and
enforceable notwithstanding the invalidity, unenforceability, impossibility or
illegality of performance of any other Operative Document.

     (b) Amendment. Neither this Lease nor any of the terms hereof may be
         ---------
terminated, amended, supplemented, waived or modified orally, but only by an
instrument in writing signed by the party against which the enforcement of the
termination, amendment, supplement, waiver or modification is sought and, unless
and until Lessee and Lessor shall have received written notice from Indenture
Trustee that the Lien of the Indenture on the Indenture Estate has been released
by Indenture Trustee, no amendment, supplement or waiver by Lessor or Lessee
shall be effective without the written consent of Indenture Trustee, except as
expressly provided in the Indenture.

modify, define or limit any of the terms or provisions hereof.

     (d) Successors and Assigns. This Lease shall be binding upon and inure to

         --------------
Lease will have an undivided possessory interest in the Transponders during the
Lease Term and GMHE will have no right to exclude STLC from use or occupancy of
the Transponders during the Lease Term. STLC and GMHE are jointly and severally
liable for all obligations under the Lease. Except as expressly provided herein,
any notice to or from, or election or waiver by, STLC hereunder shall constitute
notice to or from, or election or waiver by, GMHE for all purposes and, as
between STLC and GMHE, STLC shall have the right to exercise all rights of
Lessee hereunder to the exclusion of GMHE.

     (g) Limitation of Liability of the Trust Company. It is expressly
         --------------------------------------------

is executed and delivered by the Trust Company not in its individual capacity

undertakings and agreements made herein by the Owner Trustee are not personal

the Owner Trustee, as Trustee, (iii) actions to be taken by the Owner Trustee
pursuant to its obligations hereunder may, in certain instances, be taken by the
Owner Trustee only upon specific authority of the Owner Participant, and (iv)
except as expressly set forth herein or in the other Operative Documents or the
Hughes Agreements, nothing herein contained shall be construed as creating any
liability of the Trust Company, or any incorporator or any past, present or
future subscriber to the capital stock of, or stockholder, officer or director
of, the Trust Company, all such liability, if any, being expressly waived by the
other parties hereto, and by any Person claiming by, through or under them.

          (c)  The parties may waive any of the requirements of the foregoing

          SECTION 2.04.  Expiration of Obligations of Participants.
                         -----------------------------------------
Notwithstanding any provision to the contrary contained herein, the obligation
of the parties hereto to enter into the Operative Documents and the Hughes

          SECTION 2.05.  In-Service Date Appraisal.  As promptly as practicable
                         -------------------------
after the launch of the Satellite, but in no event less than the greater of five
days and three Business Days prior to the In-Service Date, Agent, Owner
Participant and Seller shall have received from the Independent Appraiser a
draft of an amendment to the Appraisal to be delivered in final form on the In-
Service Date, in respect of which Consulting Appraiser shall have been permitted
to consult with Independent Appraiser, reasonably satisfactory in form and
substance to Agent and Seller (the "In-Service Date Appraisal") stating whether
or not, on the In-Service Date, the conclusions of the Appraisal are true or
whether there are necessary amendments to the conclusions of the Appraisal. Such
amendments, if any, to the conclusions of the Appraisal shall be based solely on
changes in the assumptions regarding the physical characteristics (including any
downward adjustment to fuel made by HCG pursuant to Section 5.05(g) and
including defects) of the Satellite and the Transponders manifesting themselves
following the launch (which characteristics are referred to in Appendix D to the
Appraisal), and may not take into account any factors or conditions whatsoever
other than the physical characteristics described above; in particular, all
other assumptions and methodologies will remain constant. If there are
adjustments to the Appraisal conclusions, then Lessor's Cost, the Basic Term,
Fair Market Sales Value on the EBO Date and Fair Market Sales Value at the end
of the Basic Term shall be adjusted, as appropriate; provided that Lessor's Cost
                                                     --------
derived from the In-Service Date Appraisal for any Transponder will not increase
by more than 10% of Lessor's Cost derived from the Appraisal and the Lease Term
Will not be extended beyond 11-1/2 years.

          SECTION 2.06.  Funding on In-Service Date. Subject to the Equity Cap,
                         --------------------------                          
on the In-Service Date:

          (a)  Owner Participant shall make available to Owner Trustee the full
     amount of its Commitment for each Transponder owned by Owner Trustee, and
     the proceeds of such funding will be used by Owner Trustee to repay, to the
     greatest extent possible, the principal of and accrued interest on the
     Series C Notes (or the portion of the Series A Notes as provided in Section
     2.10, if the Series A Notes have not been refinanced), and the balance, if
     any, will be paid by Owner Trustee to Seller as an upward adjustment to the
     purchase price of the Transponders.

          (b)  Owner Participant shall make available to Owner Trustee an amount
     with respect to each Transponder equal to the sum of (i) the principal of,
     Variable Amount, if any, and accrued interest on the outstanding Series E
     Note (or the principal of and accrued interest on the outstanding Series D
     Note(s) if the Series D Notes have not been refinanced) related to such
     Transponder and (ii) the Transaction Costs related to such Transponder due
     and payable in accordance with Section 9.01 on the In-Service Date, and the
     proceeds of such funding will be used by Owner Trustee on the In-Service
     Date to refund in full the Series E Note(s) (or the Series D Note(s) if the
     Series D Note(s) have not been refinanced) related to such Transponder and
     to pay the Transaction Costs related to such Transponder due and payable in
     accordance with Section 9.01.

          (c)  The funding described in paragraphs (a) and (b) above shall be
     made by wire transfer of immediately available funds to the account
     specified by Owner Trustee by 12:00 p.m., New York time, on the In-Service
     Date.

          SECTION 2.07.  Defaulting Participant.  (a) If Owner Participant shall
                         ----------------------                              
fail to make all or any portion of the payments required by Sections 2.06(a) and
(b) in respect of any Transponder available to Owner Trustee hereunder on the
In-Service Date (Owner Participant, for the purpose of this Section 2.07, being
called "Defaulting Participant", such failure being called a "Commitment Funding
Default" and the amount in respect of which such failure has occurred being
called the "Defaulted Amount"), Owner Trustee shall promptly give each party
hereto telephonic notice (to be confirmed promptly in writing) of such
Commitment Funding
<PAGE>
 
                                                                              10

Default and the Defaulted Amount. In such event, unless (i) (A) such Commitment
Funding Default resulted from a mechanical problem in an otherwise timely wire
transfer, (B) the Defaulted Amount is received by Owner Trustee no later than
12:00 p.m. on the Business Day next following the day on which such amount
should have been received and (C) there is no change in the In-Service Date
(notwithstanding such delay in payment) or (ii) with Lessee's consent, Agent or
an Affiliate of Agent that would be, or has its obligations guaranteed by, a
Permitted Institution (on behalf of Defaulting Participant) cures in full such
Commitment Funding Default by 12:00 p.m. on the third Business Day after the In-
Service Date, then HCG shall advance to Defaulting Participant and, on behalf of
Defaulting Participant, pay to Owner Trustee, the Defaulted Amount. The Person
effecting any cure pursuant to this Section 2.07(a) shall pay to Owner Trustee
(and Owner Trustee shall pay to Indenture Trustee upon receipt), in addition to
the Defaulted Amount, the amount of any interest accrued on the Series C Notes
(or, if the Series A Note has not been refinanced, that portion of the Series A
Note that was to be refinanced with the Commitment on the In-Service Date) and
the Series E Note(s) (or, if the Series D Notes have not been refinanced, the
Series D Note(s)) from the In-Service Date to but not including the date of such
cure, and such interest shall not constitute Transaction Costs (and the payment
of such interest shall not result in any Rental Adjustment) or be included in
any calculation of the Equity Cap.

          (b)  If HCG advances the Defaulted Amount, such advance shall
constitute a demand recourse loan to Defaulting Participant which shall be
evidenced by Defaulting Participant's Note.  In addition, in the event of such
advance by HCG in respect of a Commitment Funding Default, (i) because HCG and
Owner Participant agree that it is difficult to ascertain the damages that will
be suffered by HCG as a result of such Commitment Funding Default, HCG and Owner
Participant agree that Defaulting Participant shall pay liquidated damages to
HCG in an amount equal to 10% of Lessor's Cost of the Transponders in respect of
which such Commitment Funding Default occurred (it being understood that in the
case of a partial funding of the Commitment with respect to a Transponder,
Lessor's Cost of such Transponder for the purposes of this clause (i) shall be
reduced by the amount of such partial funding), (ii) Lessee shall have the right
to offset the amount due and owing under the Defaulting Participant's Note and
such liquidated damages against any payment payable by Lessee to

                                                                              11

Owner Trustee or Defaulting Participant under any Operative Document other than
any portion of any payment if such payment shall have been assigned to Indenture
Trustee and the Indenture shall provide that such portion is to be applied to
any amount due from Owner Trustee to the Noteholders in the absence of an
Indenture Default or an Indenture Event of Default, (iii) the Tax
Indemnification Agreement without any action by any Person automatically shall
cease to be in force and shall become null and void ab initio and (iv)
                                                    -- ------        
Defaulting Participant shall not have the right to transfer its interest in
Lessor's Estate without the prior written consent of Lessee, which consent may
be withheld by Lessee in its sole discretion.

          (c)  If any Commitment Funding Default is cured pursuant to Section
2.07(a)(i) or (ii), and if on the In-Service Date there would have been an
upward adjustment to the purchase price of the Transponders pursuant to Section
2.01(b), then the Person curing such Commitment Funding Default shall also pay
to Owner Trustee (and Owner Trustee shall pay to Seller) an amount equal to
interest on the amount of such upward adjustment, computed at the Prime Rate
from and including the In-Service Date to but excluding the date of such cure.

          SECTION 2.08.  In-Service Date Adjustments to Series B Notes.  (a) If
                         ---------------------------------------------      
the sum of the principal amount of the Series B Notes outstanding with respect
to a Transponder on the In-Service Date plus the amount of interest accrued
thereon to but excluding the In-Service Date exceeds the Debt Commitment (as
determined on the In-Service Date) with respect to such Transponder, then, on
the In-Service Date, such excess will be at the option of Lessee, either (i)
exchanged, in accordance with Section 2.13 of the Indenture, for unsecured notes
of HCG or Lessee, if Lessee is then a Subsidiary of GMHE, to be issued under a
new indenture, guaranteed by GMHE pursuant to a guarantee in the form required
by the Indenture, or (ii) if permitted by the terms of the Series B Notes,
prepaid by Lessor on the In-Service Date with funds provided by Seller to Owner
Trustee (which funds Seller hereby agrees to provide) as a downward adjustment
to the purchase price of the Transponders.

          (b)  If the Debt Commitment (as determined on the In-Service Date)
with respect to a Transponder exceeds the sum of the principal amount of the
Series B Notes outstanding with respect to such Transponder on the In-Service
Date plus the amount of interest accrued thereon
<PAGE>
 
                                                                              12

to but excluding the In-Service Date, then, on the In-Service Date, (i) Lessee
shall arrange for Owner Trustee to issue and sell additional Series B Notes or
Series F Notes (which Series B Notes or Series F Notes Owner Trustee hereby
agrees to issue on the In-Service Date) with respect to such Transponder in an
aggregate principal amount equal to such excess and (ii) the proceeds of such
sale of additional Series B Notes or Series F Notes shall be paid by Owner
Trustee (to the extent such proceeds are actually received by Owner Trustee) to
Seller upon receipt as an upward adjustment to the purchase price of such
Transponder.

          SECTION 2.09.  In-Service Date Downward Adjustment to Commitment if
                         ----------------------------------------------------
Series B Notes Outstanding.  If after giving effect to any adjustment required 
- --------------------------                                                    
to be made in Section 2.08(a), the sum of the principal amounts of the Series B
Notes and the Series C Notes outstanding with respect to a Transponder on the
In-Service Date plus the aggregate accrued interest thereon to but excluding the
In-Service Date exceeds Lessor's Cost (as determined on the In-Service Date) for
such Transponder, Seller shall make a refund payment to Owner Trustee in the
amount of such excess as a downward adjustment to the purchase price of such
Transponder, which refund shall be used by Owner Trustee on that date to pay the
excess, if any, of the sum of the principal of and accrued interest on the
Series C Notes with respect to such Transponder over the amount of the
Commitment (as determined on the In-Service Date) for such Transponder.

          SECTION 2.10.  In-Service Date Adjustments to Series A Notes.  If the
                         ---------------------------------------------      
Series A Notes with respect to a Transponder shall not have been refinanced
prior to the In-Service Date, then, on the In-Service Date, all or a portion of
the Commitment for such Transponder will be used by Owner Trustee to redeem a
portion of the principal amount of Series A Notes (including accrued interest
thereon) then outstanding with respect to such Transponder such that the
principal amount of Series A Notes (including accrued interest thereon)
remaining outstanding with respect to such Transponder after such redemption
shall equal the Debt Commitment as determined on the In-Service Date for such
Transponder. If the amount of the Commitment for such Transponder is
insufficient to effect such redemption to reduce the principal amount of Series
A Notes (including accrued interest thereon) then outstanding with respect to
such Transponder to an amount equal to the Debt Commitment for such Transponder,
then Seller shall make a refund payment to Owner Trustee, as a downward
adjustment to the
<PAGE>
 
                                                                              13

purchase price of such Transponder, in the amount required to complete such
redemption and Owner Trustee shall use such funds to complete such redemption on
the In-Service Date.  If the amount of the Commitment for such Transponder shall
exceed the amount necessary to effect such redemption to reduce the principal
amount of Series A Notes (including accrued interest thereon) then outstanding
with respect to such Transponder to an amount equal to the Debt Commitment for
such Transponder, then, after effecting such redemption, Owner Trustee shall pay
on the In-Service Date the balance of the Commitment for such Transponder to
Seller as an upward adjustment to the purchase price of such Transponder.

          SECTION 2.11.  Series G Notes; Instruction Certificate.  (a) If the
                         ---------------------------------------          
Series A Notes shall not have been refinanced prior to the In-Service Date,
then, on and after the In-Service Date Lessee may arrange for the issuance by
Owner Trustee of Series G Notes to refinance the then outstanding principal of
the Series A Notes and any interest accrued thereon to but not including the In-
Service Date, in accordance with the terms and conditions of the Indenture
(including, without limitation Section 2.3(a)(vii) thereof) and Article X
hereof.

          (b)  Owner Trustee, at the direction of Owner Participant, shall
execute and deliver to Indenture Trustee an Instruction Certificate whenever the
provisions of the Indenture require the delivery to Indenture Trustee of such a
certificate.

          SECTION 2.12.  Deferred Equity Amount.  (a) Subject to Section 
                         ----------------------                               
2.12(b), on any date between the In-Service Date and the Basic Term Commencement
Date on which a payment of principal of or interest on any of the Notes is due
as referred to in Section 3(b)(i)(A) or 3(c)(ii) of the Lease, Owner Participant
shall provide Owner Trustee with the Deferred Equity Amount equal to the amount
of principal of and interest on such Notes due and payable on such date or
dates, other than the amount required to be paid by Lessee pursuant to the last
sentence of Section 3(b)(i)(B) of the Lease on the Interim Rent Payment Date.

          (b)  To the extent any funding of the Deferred Equity Amount by Owner
Participant, when combined with the other payments required to be funded by
Owner Participant pursuant to Section 2.01(b) (without giving effect to the
final sentence thereof) or Section 9.01 (without giving effect to the second
sentence of Section 9.01(b)), would

Supplemental Rent on an After-Tax Basis.

     (in respect of which Consulting Appraiser shall have been permitted to
     consult with Independent Appraiser) by Independent Appraiser, addressed to
     it in a form and substance satisfactory to Agent and Cravath, Swaine &
     Moore, special tax counsel for Owner Participant, and not inconsistent with
     the opinion of Independent Appraiser delivered to Lessee and referred to in
     Section 3.02 (i) hereof, containing (i) the determination of Independent
     Appraiser of the anticipated fair market value of each Transponder on the

     remaining economic useful life of each Transponder as of the anticipated 
     In-Service Date will remain at the end of the Basic Term, (iii) an estimate
     of the residual value of each Transponder at the end of the Basic Term
     (without taking into account the effect of inflation or deflation), which
     estimate shall be to the effect that each Transponder shall have a residual

     its economic useful life and to remove the Satellite from orbit at the end
     of such life, (v) the conclusion that no Transponder is "limited use
     property" and that it is reasonable to expect that each Transponder will be
     useful or usable in a commercially feasible manner at the end of the Basic
     Term by Owner Participant or a Person other than Lessee or an Affiliate
     thereof and (vi) a statement that the fees payable under the Service
     Agreement are equal to the fair market value of the services to be provided

     as of the Closing Date of Independent Appraiser of the expected fair market
     value of each Transponder at the end of the Basic Term and on the EBO Date
     (taking into account a reasonable estimate of the effect of inflation and
     deflation).  Initial Note Purchaser shall have received evidence
     satisfactory to it (in the form of a copy of the relevant sections of the
     opinion referred to in clause (i) of Section 3.02) as to Independent
     Appraiser's estimate of the fair market value of each Transponder as of the

The obligations of HCG and Seller to enter into the Operative Documents and

shall be subject to the fulfillment to the satisfaction of, or waiver by, HCG or
Seller, as applicable, prior to or on the Closing Date, of the following

form and scope from the Independent Appraiser on the Closing Date, not
inconsistent with the Appraisal delivered to Owner Participant pursuant to
Section 3.01(1) hereof, (A) to the effect that the Transponders will have, at
the end of the Basic Term, in excess of 25% of their economic useful life
remaining, measured from the anticipated In-Service Date, (B) stating the
anticipated fair market value of the Transponders as of the anticipated In-
Service Date and (C) to such other matters as HCG shall reasonably require, (ii)

                         ---------------------------------------------------   
HCG represents and warrants to each of the other parties hereto that:

          (a)  It is a corporation duly organized, validly existing and in good
     standing under the laws of the state of its incorporation, and has all
     requisite corporate power and authority to operate and own or hold under
     lease the properties it purports to operate and own or hold under lease, to
     transact the business it transacts and to otherwise enter into and perform
     its obligations under each Operative Document to which it is or will be a
     party. HCG is duly qualified to do business as a foreign corporation and is
     in good standing in each jurisdiction wherein the failure to do so would
     have a material adverse effect on the conduct of its business and
     operations as presently conducted or on its ability to perform its
     obligations under the Operative Documents and Hughes Agreements to which it
     is or will be a party.

          (b)  Each Operative Document and Hughes Agreement to which HCG is or
     will be a party has been duly authorized by all necessary corporate action
     on the part of, and has been or on or prior to the Closing Date (or the In-
     Service Date with respect to the Lease) will be duly executed and delivered
     by, it and neither the execution and delivery thereof, nor the consummation
     by it of the transactions contemplated thereby (including, without
     limitation, the operation of the Transponders) nor compliance by it with
     any of the terms and provisions thereof (i) requires any approval of
     stockholders or approval or consent of any trustee or holders of any of its
     indebtedness or obligations, (ii) contravenes any law, judgment,
     governmental rule or regulation or order applicable to or binding on it or
     any of its properties, the contravention of which would have a material
     adverse effect on the conduct of its business and operations as presently
     conducted or the performance of its obligations under the Operative
     Documents and the Hughes Agreements to which it is or will be a party,
     (iii) contravenes or results in any breach of, or constitutes any default
     under, any indenture, mortgage, chattel mortgage, deed of trust,
     conditional sales

                                                                              27

     contract, bank loan or credit agreement for borrowed money, contract or
     other agreement or instrument to which it is a party or by which it or any
     of its properties may be bound or affected, the contravention, breach or
     default of which would have a material adverse effect on the conduct of its
     business and operations as presently conducted or the performance of its
     obligations under the Operative Documents and the Hughes Agreements to
     which it is or will be a party, (iv) contravenes its corporate charter or
     by-laws or (v) results in the creation of any Lien (other than Permitted
     Liens described in clauses (a) and (b) of the definition thereof) upon the
     Transponders or any material property of HCG.

          (c)  Neither the execution and delivery by it of the Operative
     Documents or Hughes Agreements to which it is or will be a party, nor the
     consummation by it of any of the transaction (including, without
     limitation, the operation of the Transponders) contemplated thereby,
     requires the consent, approval or authorization of, the giving of notice
     to, or the registration with, the recording or filing of any document with,
     or the taking of any other action in respect of, any Governmental Body, or
     any publication requirement under California Civil Code Section 3440,
     except (i) such of the foregoing as have been obtained, given or done (each
     of which is in full force and effect and adequate for its purpose), (ii)
     the filings and actions described in clause (ii) of Section 4.01(g), and
     (iii) such routine notification from Seller to the FCC as may be required
     after the Closing Date under the laws in existence on the Closing Date.
     Except as set forth in Schedule 3.01(g), as of the Closing Date, any and
     all notifications that may be required to be given by Seller to the FCC
     pursuant to the foregoing clause (iii) are routine in nature and for
     informational purposes only, and no such notice as of the Closing Date
     requires any official action or determination by the FCC as of the Closing
     Date, is subject to approval or disapproval by the FCC or as of the Closing
     Date gives rise to a right by any third party to file a petition to deny.

          (d)  Each Operative Document and Hughes Agreement to which HCG is or
     will be a party constitutes or, when executed, will constitute the legal,
     valid and binding obligation of HCG, enforceable against HCG in accordance
     with its terms, except as such enforcement

                                                                              28

     affecting creditors' rights generally and to general principles of equity.

          (e)  Except as disclosed in writing to Indenture Trustee, Owner
     Trustee, Owner Participant and Initial Note Purchaser prior to the
     execution of this Agreement, there are no actions, suits or proceedings
     pending against HCG in any court or before any arbitrator of any kind or
     before or by any Governmental Body, or to the knowledge of HCG threatened,
     which question the legality or validity of any of the Operative Documents
     or Hughes Agreements to which HCG is or will be a party or the transactions
     contemplated thereby or which, individually or in the aggregate, if
     adversely determined, would have a material adverse effect on the conduct
     of its business and operations as presently conducted or on its ability to
     perform its obligations under the Operative Documents or the Hughes
     Agreements to which it is or will be a party.

          (f)  HCG is not in violation of any Order of any Governmental Body,
     which violation would have a material adverse effect on the conduct of its
     business and operations as conducted on the date hereof.

          (g)  On the Closing Date, upon delivery of the Bill of Sale to Owner
     Trustee and payment of Initial Lessor's Cost for the Transponders by Owner
     Trustee to Seller (i) Seller will deliver to Owner Trustee good and
     marketable title to the Transponders free and clear of all Liens other than
     Permitted Liens described in clauses (a) and (b) of the definition thereof
     and (ii) except for the filing of a Uniform Commercial Code financing
     statement or statements covering the Indenture Estate and naming Owner
     Trustee as debtor and Indenture Trustee as secured party (which have been
     filed or received or delivered to counsel for Indenture Trustee for filing
     or recording), and except for the taking by Indenture Trustee of possession
     of the executed original counterpart of the Lease, no further action,
     including any filing or recording of any document, is necessary or
     advisable in order to establish, confirm and protect Owner Trustee's right,
     title and interest in and to the Transponders or to perfect for the benefit
     of the Noteholders the security interest in the Indenture Estate provided
     for in the Indenture (other than any part of the Indenture Estate located
     on the Satellite).

     hereby.

          (n)  HCG has filed all Federal tax returns required to be filed by it,
     and all other required tax returns in respect of which the failure to file

     effect. HCG shall not use any Transponder or authorize any third party to
     use such Transponder in breach of the Purchase Agreement, the Service
     Agreement or any Applicable Laws applicable to Owner Trustee (in its
     capacity as such Transponder owner without regard to Applicable Laws
     applicable to Owner Trustee solely because of its being engaged in a
     regulated activity of any type other than the owning and leasing of such
     Transponder), Owner Participant (in its capacity as such Transponder owner
     without regard to Applicable Laws applicable to Owner Participant solely
     because of its being engaged in a regulated activity of any type other than
     the owning and leasing of such Transponder),

     such third party or such Transponder (in each case, other than Applicable
     Laws as to which noncompliance would not have an Adverse Effect), or in
     violation of any authorization relating to such Transponder or the
     Satellite or HCG issued by any Governmental Authority having jurisdiction
     over such Transponder, the Satellite or HCG (other than (i) any provision
     thereof as to which noncompliance would not have an Adverse Effect or (ii)
     unless the validity of such Applicable Law or authorization is being
     contested in good faith and by appropriate proceedings (but only so long as
     such proceedings do not involve any risk of civil or criminal liability to
     Owner Trustee or Owner Participant, and do not involve any material danger
     of the sale, forfeiture, loss or diminution in value of such Transponder or
     the rights of Owner Trustee or Owner Participant under any Hughes Agreement
     or any Operative Document and adequate reserves with respect thereto shall
     have been established in accordance with GAAP). This Section 5.01(k) shall
     expire on the Execution Date.
 
          (l)  Maintenance. With respect to each Transponder, HCG hereby agrees
               -----------
     to require Hughes Services to fulfill all of its obligations under the
     Service Agreement. Seller hereby agrees to fulfill all of its obligations
     under the Purchase Agreement. In the event that at any time prior to the
     Execution Date the Service Agreement shall no longer be in full force and
     effect or Hughes Services shall fail to perform its obligations thereunder
     with respect to such Transponder, HCG, at its expense, shall maintain,
     manage and monitor, or cause to be maintained, managed and monitored, the
     Satellite and such Transponder in good working order and repair, ordinary
     wear and tear excepted, (i) in accordance with the higher of (A) customary
     industry standards employed by owners of Ku-Band or C-Band transponders, as
     applicable, on domestic communications satellites or (B) standards at least
     equal to those used by Hughes Services or any of its Affiliates prior to
     such failure of performance for other transponders on the Satellite or on
     another similar satellite owned, leased or operated by Hughes Services or
     any of its Affiliates (if at the time Hughes Services or any Affiliate
     thereof maintains, manages or monitors satellites similar to the Satellite
     for similar commercial purposes), (ii) in compliance with all Applicable
     Laws (other than Applicable Laws as to which noncompliance would not have
     an Adverse
 
<PAGE>
 
                                                                              44


     Effect) and (iii) in accordance with all applicable requirements of any
     insurance policy then in effect as required by Section 5.01(n) hereof. The
     foregoing notwithstanding, if, with respect to any Transponder, Contractor
     or Substitute Service Provider is unable temporarily to perform its
     maintenance obligations under the Service Agreement or any Substitute
     Service Agreement due to any Force Majeure Event, then, provided such
     temporary failure to perform does not cause a permanent material diminution
     in the value of such Transponder and is capable of cure before any such
     permanent diminution in value would result, such failure shall not
     constitute a breach of HCG's obligations under this Section 5.01(l).
 
          Without limiting the generality of the foregoing, at any time prior
     to the Execution Date, if the Service Agreement shall not be in effect, HCG
     will arrange for Owner Trustee to enter into and HCG will keep in full
     force and effect until the end of the Lease Term an agreement for the
     provision of services (the "Substitute Service Agreement") comparable to
     those to be provided by Hughes Services under the Service Agreement at a
     reasonable cost with a sound and reputable service provider, which may or
     may not be an Affiliate of Hughes Services (the "Substitute Service
     Provider"), and which such provider shall be reasonably acceptable to Owner
     Trustee. If Owner Trustee enters into a Substitute Service Agreement, it
     will assign its rights under such agreement to HCG at the time it enters
     into such agreement on the same terms and conditions contained in Section
     5(b)(ii) of the Lease. This Section 5.01(l) shall expire on the Execution
     Date.
     
          (m)  Compliance with Law. HCG or Contractor shall have and maintain
               -------------------
     all permits, licenses and approvals required by the FCC or under any
     Applicable Law to operate the Satellite and such Transponder and shall
     satisfy the requirements of the FCC and any statute, regulation or order
     applicable to operators, users or lessees of such Transponder, provided,
                                                                    --------
     however, that HCG shall not be deemed to have breached the foregoing
     -------
     covenant unless such non-maintenance or non-satisfaction would have an
     Adverse Effect. Prior to the Execution Date, to the extent permitted by
     law, HCG or any Affiliate thereof shall prepare and file in timely fashion,
     or where Owner Trustee, Owner Participant or Indenture Trustee shall be
     required so
 
<PAGE>
 
                                                                              45


     to file, prepare and deliver to such Person within a reasonable time prior
     to the date for filing, any reports with respect to any Transponder which
     are required to be filed with any Governmental Body. Owner Trustee shall
     notify HCG promptly after Owner Trustee has Actual Knowledge of any reports
     or filings required of Owner Trustee by law in connection with its
     ownership of the Transponders; provided, however, that Owner Trustee shall
                                    --------  -------
     not incur any liability to HCG for failure so to notify HCG. If, prior to
     the Execution Date, HCG shall fail to timely prepare, deliver or file any
     such report solely as a result of the failure of Owner Trustee, Owner
     Participant or Indenture Trustee timely to provide HCG with (i) any
     information required in such report which is in the possession of Owner
     Trustee, Owner Participant or Indenture Trustee and is not reasonably
     available to HCG or (ii) notice of the requirement of such report if such
     report is required as to Owner Trustee, Owner Participant or Indenture
     Trustee for any reason other than such Person's interest in the
     Transponders, HCG shall incur no liability to any such Person failing to
     provide such information or notice, to the extent such liability is
     incurred by the failure to provide such information or notice (unless HCG
     already had Actual Knowledge of such requirement, HCG fails to request such
     information from such Person and such failure has an Adverse Effect). Owner
     Trustee hereby appoints HCG its attorney-in-fact, to the extent permissible
     by Applicable Law, to execute such reports in the name of Owner Trustee and
     to file such reports, and Owner Trustee shall cooperate in furnishing HCG
     such information as is available to it which must be included in such
     reports. Upon demand, HCG shall reimburse, Owner Trustee, Owner Participant
     or Indenture Trustee on an After-Tax Basis for any reasonable out-of-pocket
     costs incurred by each such Person, respectively, in connection with the
     preparation and filing of any such reports. HCG shall, on a periodic basis,
     furnish Owner Trustee, Owner Participant or Indenture Trustee with a copy
     of all reports filed by HCG on behalf of any such Person pursuant to this
     Section 5.01(m). This Section 5.01(m) shall expire on the Execution Date.
 
          (n) Insurance.  HCG agrees to maintain any insurance with respect to
              ---------
     the Transponders that would be required to be maintained by Lessee under
     Section 9 of the Lease, on the terms and conditions therein
 
<PAGE>
 
                                                                              46


     specified, if the Lease were in effect. This Section 5.01(n) shall expire
     on the Execution Date.

          (o) Transponder Spares. (i) If Seller furnishes a Transponder Spare to
              ------------------                                              
     Buyer under Section 8.01 of the Purchase Agreement as a substitute for an
     equipment unit which has caused Buyer's Transponder to suffer a Confirmed
     Failure, then Seller agrees that such Transponder Spare shall be free and
     clear of all Liens other than Permitted Liens of the type described in
     clauses (a) and (b) of the definition thereof and that Buyer's return of
     its substituted Transponder equipment unit to Seller shall be made without
     representation or warranty of any kind except as to the absence of Lessor
     Liens or Owner Participant Liens.

          (ii) Seller hereby agrees that, if it uses any Transponder Spares
     pursuant to the last sentence of Section 8.01 of the Purchase Agreement, it
     will do so in a technically prudent manner. This Section 5.01(o) shall
     expire upon the commencement of the Post Lease Term.

          (p)  [Intentionally Omitted]

          (q)  Outage Units. HCG hereby confirms that, in calculating the number
               ------------                                                   
     of Outage Units that may occur in one day for the purposes of Section 13 of
     the Purchase Agreement, each fifteen (15) minute period during such day
     that Buyer's Transponder(s) fail to meet the Transponder Performance
     Specifications shall constitute one Outage Unit (e.g., if Buyer's Transpon-
                                                      ----                   
     der(s) should fail to meet the Transponder Performance Specifications for
     five consecutive hours in one day, there would result 20 Outage Units and
     Buyer's Transponder(s) would suffer a Confirmed Failure). HCG applies this
     interpretation uniformly with respect to all owners of transponders on the
     Satellite.

          (r)  Merger, Consolidation. The provisions of Section 13 of the Lease
               ---------------------                                         
     are hereby incorporated by reference herein and made a part hereof as
     effective as if set forth in full herein, except that references therein to
     the Lease shall be deemed to refer to this Agreement. This Section 5.01(r)
     shall expire on the Execution Date.

          (s)  The provisions of Section 6(c) of the Lease are hereby
     incorporated by reference herein and made a

                                                                              47


     part hereof as effective as if set forth in full herein; provided however,
                                                              -------- -------
     that, prior to the Execution Date, HCG may not assign, in whole or in part,
     its leasehold interest in the Lease (but may enter into other Use
     Agreements as provided therein). Without derogating from Lessee's
     obligations under this Section 5.01(s), HCG represents and warrants to and
     agrees with Owner Participant and Owner Trustee that no Existing Lease
     entered into prior to the In-Service Date has or will have a term
     (including all renewal terms) that extends beyond the Basic Term. This
     Section 5.01(s) shall expire on the Execution Date.
 
          (t)  Further Assurances. HCG, at its reasonable expense, shall
               ------------------
     promptly and duly execute and deliver to Owner Trustee, Owner Participant
     and Indenture Trustee such documents and assurances and take such further
     action as Owner Trustee (and Indenture Trustee) may from time to time
     reasonably request in order to carry out more effectively the intent and
     purpose of the Operative Documents and to establish and protect the rights
     and remedies created or intended to be created in favor of Owner Trustee
     thereunder to establish, perfect (to the extent practicable in the case of
     the Transponders), and maintain Owner Trustee's right, title and interest
     in and to the Transponders and the Indenture Estate and, for the benefit of
     the Indenture Trustee, the lien and security interest in the Indenture
     Estate provided for in the Indenture, subject to no Lien other than
     Permitted Liens, including, without limitation, if requested by Owner
     Trustee, Owner Participant or Indenture Trustee, at the expense of HCG, the
     recording or filing of appropriate memoranda, or of such financing
     statements or other documents with respect to the Operative Documents as
     any of Owner Trustee, Owner Participant or Indenture Trustee may from time
     to time reasonably request, and Owner Trustee agrees promptly to execute
     and deliver such of the foregoing financing statements or other documents
     as may require execution by Owner Trustee and to the extent permitted by
     Applicable Laws, HCG hereby authorizes any such financing statements to be
     filed without the necessity of signature by HCG. This Section 5.01(t) shall
     expire on the Execution Date.

          SECTION 5.02. Covenants of Owner Participant. Owner Participant
                        ------------------------------                 
further covenants to and with each of the other parties hereto that:

          (a)  No Liens. It will keep the Transponders, Lessor's Estate and the
               --------                                                      
     Indenture Estate free and clear of Owner Participant Liens. Owner
     Participant shall pay, and shall indemnify and hold harmless each other
     Indemnitee and HCG (if prior to the Execution Date) and Lessee (if on or
     after the Execution Date) (and each of HCG's or Lessee's, as applicable,
     respective successors, assigns, officers, directors, servants, employees
     and agents) from, any and all liabilities, obligations, losses, damages,
     penalties, claims, actions, suits, costs, expenses and disbursements,
     including legal fees and expenses, of whatsoever kind and nature, imposed
     on, incurred by or asserted against any such Person solely as the result of
     the failure of Owner Participant to comply with this Section 5.02(a).

          (b)  No Prepayment. Unless an Event of Default under the Lease shall
               -------------                                                
     have occurred and be continuing under Section 15 thereof, without the prior
     written consent of HCG (if prior to the Execution Date) and Lessee (if on
     or after the Execution Date), Owner Participant will not, and will not
     cause, authorize or permit Owner Trustee to, directly or indirectly prepay,
     redeem, refund or refinance any Note other than pursuant to Section 2.6 or
     2.7 of the Indenture and other than in the event of a purchase of the Notes
     pursuant to Section 2.11 of the Indenture (but nothing herein shall
     prohibit Owner Participant from purchasing the Notes on the open market).
     This Section 5.02(b) shall not be deemed to permit prepayment of the Notes
     except as permitted by the Indenture.

          (c)  Successor Owner Trustee. Owner Participant shall not appoint or
               -----------------------                                      
     cause or allow to be appointed a successor to Owner Trustee or an
     additional or separate trustee under the Trust Agreement without giving
     prior written notice of such appointment (including notification of the
     principal place of business of each such successor, additional or separate
     trustee) to Seller (if prior to the Execution Date), Lessee and Indenture
     Trustee. Owner Participant shall cause any such successor, additional or
     separate trustee, simultaneously with its assumption of duties in such
     capacity, to take all actions as may be reasonably requested by Indenture
     Trustee, Seller (if prior to the
<PAGE>

     Execution Date) or Lessee (including, without limitation, the filing of
     financing statements), at Seller's (if prior to the Execution Date) or
     Lessee's expense, in order to establish, preserve, protect and perfect (to
     the extent practicable in the case of the Transponders) Seller's (if prior
     to the Execution Date) and Lessee's interest in and to the Transponders and
     Seller's (if prior to the Execution Date) and Lessee's rights under this
     Agreement, the other Operative Documents and the Hughes Agreements and to
     execute and deliver to Seller (if prior to the Execution Date) or Lessee
     (if on or after the Execution Date) a counterpart of the Consent and
     Agreement and, so long as any Notes are outstanding, the mortgage and
     security interest of Indenture Trustee in the Indenture Estate granted or
     intended to be created under the Indenture and Indenture Trustee's rights
     under this Agreement, the other Operative Documents, and the Hughes
     Agreements, subject only to Permitted Liens. In the event of Trust
     Company's resignation, bankruptcy or insolvency, or disqualification
     unrelated to its relationship with Owner Participant, the expenses incurred
     in connection with the appointment of a successor Owner Trustee as a result
     thereof shall be paid by Seller (if prior to the Execution Date) or Lessee.
     Otherwise, in connection with Owner Participant's appointment of a
     successor Owner Trustee, the expenses incurred in connection therewith and
     any incremental increase in fees payable to the successor Owner Trustee
     shall be paid by Owner Participant.
 
          (d)  Performance of Obligations.  Owner Participant will perform and 
               --------------------------
     comply with all obligations imposed on Owner Participant pursuant to the
     provisions of the Operative Documents in accordance with the terms and
     conditions of each thereof and for the benefit and only for the benefit of
     the parties to whom such obligations are owed.

          (e)  Instructions to Owner Trustee. Owner Participant will not
               -----------------------------
     instruct or otherwise direct Owner Trustee to take, or omit to take, any
     action in violation of the express covenants and agreements of Owner
     Trustee in any Operative Document or any of the Hughes Agreements. Owner
     Participant will not unreasonably withhold its consent to or authorization
     of any consent requested by Owner Trustee under the terms of any Operative
     Document or any of the Hughes Agreements
<PAGE>
 
                                                                              50


     which by its terms may not be unreasonably withheld by Owner Trustee.

          (f)  Termination of Trust Agreement. Without the prior written consent
               -------------------------------                                 
     of Indenture Trustee, prior to the expiration or earlier termination of the
     Lease pursuant to its terms, Owner Participant will not terminate or
     revoke, or consent to the termination or revocation of, the Trust
     Agreement, or, prior to the release of the Lien of the Indenture on the
     Indenture Estate, amend or modify the Trust Agreement in any manner that
     would adversely affect the Indenture Estate or limit in any material manner
     the rights of Indenture Trustee set forth in the Indenture (except as may
     be expressly permitted by the Indenture). If the Trust Agreement is revoked
     or terminated, any transfer of the Transponders in connection therewith
     shall comply with the applicable provisions of Section 11.01 of the
     Purchase Agreement. Owner Participant and Owner Trustee shall comply in all
     respects with the provisions of Articles X and Section 11.01 of the Trust
     Agreement.

          (g)  [Intentionally Omitted]

          (h)  Repayment Amount. Owner Participant shall cause Owner Trustee to
               -----------------                                              
     provide to Lessee and Indenture Trustee the notice contemplated by Section
     3(c) of the Lease in the circumstances specified therein.

          (i)  Owner Participant as Competitor. If HCG shall have notified Owner
               --------------------------------                                
     Participant of any merger, acquisition or other similar event or condition
     that would be reasonably likely to cause Owner Participant to become a
     Competitor, or if Owner Participant has become a Competitor, or if Owner
     Participant has Actual Knowledge of any such event or condition that might
     be reasonably likely to cause it to become a Competitor, Owner Participant
     will, as promptly as practicable (taking into account the effect of
     Applicable Laws on whether or not any such event or condition has been
     previously publicly disclosed), deliver to HCG an Officer's Certificate of
     Owner Participant confirming or denying such event or condition and whether
     Owner Participant has become a Competitor. If Owner Participant confirms
     such event or condition, Owner Participant shall take all reasonable
     measures with respect to all confidential and Proprietary Information
     necessary to protect HCG from any adverse competitive impact that
<PAGE>
 
                                                                              51



     could arise from disclosure of such information. Owner Participant
     acknowledges that HCG will suffer irreparable harm in the event Owner
     Participant does not comply with its obligations under this
     Section 5.02(i) and agrees that HCG shall be entitled to specific
     performance of such obligations.

          (j) Election to Retain Title. If Owner Trustee shall elect or shall be
              -------------------------                                        
     deemed to have elected to retain title to the Transponders pursuant to
     Section 8(a) or 8(c) of the Lease, Owner Participant will make the required
     amount of funds available to Owner Trustee and will otherwise cause Owner
     Trustee to perform its obligations under such Section 8(a) or 8(c) in
     accordance with the terms thereof.

          (k) Notice of Indenture Event of Default. Promptly after Owner
              -------------------------------------                    
     Participant has Actual Knowledge that any Indenture Event of Default or
     Indenture Default attributable to Owner Participant has occurred and is
     continuing, Owner Participant shall deliver to Indenture Trustee, HCG (if
     prior to the Execution Date) and Lessee (if on or after the Execution Date)
     a notice of such Indenture Event of Default or Indenture Default describing
     the same in reasonable detail and, together with such notice or as soon
     thereafter as possible, a description of the action that Owner Participant
     has taken, is taking and proposes to take with respect thereto.

          (1) Capitalization of Owner Participant. Commencing on the date hereof
              ------------------------------------                             
     to and including the In-Service Date, Owner Participant shall maintain
     equity capital in an amount not less than 3% of anticipated Initial

     amount of such Stipulated Loss Value from the date as of which such
     Stipulated Loss Value is computed until the date of actual payment; and

     deliver such documents evidencing such transfer as HCG shall reasonably
     request, and HCG shall indemnify Owner Trustee on an After-Tax Basis for
     Owner Trustee's reasonable expenses incurred in connection with such

     private sale, as Owner Trustee may determine, or otherwise may dispose of,
     hold, use, operate, keep idle, lease for any period to others the
     Transponders, all on such terms and conditions and at such place or places
     as Owner Trustee may determine and all free and clear of any rights of HCG
     and of any claim of HCG, in equity, at law or by statute, whether for loss
     or damage or otherwise and HCG shall use its best efforts to obtain or
     assist Owner Trustee in obtaining, any necessary regulatory approvals for

     notice to HCG requesting that the Fair Market Sales Value or Fair Market
     Rental Value of such Transponder be determined, demand that HCG pay to
     Owner Trustee, and HCG shall pay to Owner Trustee on the 10th Business Day

     Rental Value, as the case may be, each determined on an as is, where is

     following amounts Owner Trustee, in its sole discretion, shall specify in
     such notice (together with interest on such amount at the Applicable
     Overdue Rate from the scheduled payment date to the date of actual

     Value, computed as of the In-Service Date, over the Fair Market Rental
     Value for such Transponder, valued on an as is, where is basis for the
     Basic Term, after discounting such Fair Market Rental Value semiannually
     (effective on each January 2 and July 2) to present value as of the
     scheduled payment date at the rate of interest equal to the Applicable
     Overdue Rate; (y) an amount equal to the excess, if any, of such Stipulated
     Loss Value as of the In-Service Date over the Fair Market Sales Value of
     such Transponder valued on an as is, where is basis or (z) an amount equal
     to the excess, if any, of (A) the present value computed as of such
     scheduled payment date of all installments of Scheduled Rent for the Basic
     Term, discounted semiannually (effective on each January 2 and July 2) to
     present value as of the scheduled payment date at the rate of interest
     equal to the Applicable Overdue Rate over (B) the present value, computed
     as of such scheduled payment date, of the Fair Market Rental Value of the
     Transponder for the Basic Term, discounted semiannually (effective on each
     January 2 and July 2) to present value as of the scheduled payment date at
     the rate of interest equal to the Applicable Overdue Rate.

            For all purposes of this Section 5.08(c), in the event that a
portion of the Scheduled Rent due on any scheduled payment date is designated as
an "arrears rent" on Schedule A to the Lease and there is also a payment of
Scheduled Rent due on such date that is not so designated, a portion of the Rent
Differential Amount with respect to such date shall be added to the Scheduled
Rent designated as an "arrears rent" due on such date and the remainder of such
Rent Differential Amount shall be taken into account in the computation of
Stipulated Loss Value pursuant to the definition of Stipulated Loss Value.  It
is intended that the entire amount of the Rent Differential Amount due on such
scheduled payment date shall be allocated between the Scheduled Rent designated
as an "arrears rent" due on such date and the computation of Stipulated Loss
Value, as appropriate and without duplication, in such manner as will preserve
the Owner Participant's Net Economic Return and comply with the minimum payment
requirement (it being understood that the entire amount of such Rent

                                                                              62

Amount shall be taken into consideration in making such allocation).

          All determinations of Fair Market Sales Value and Fair Market Rental
Value pursuant to this Section 5.08(c) shall be determined pursuant to the
Appraisal Procedure.  At any sale of the Transponders or any part thereof
pursuant to this Section 5.08(c), Owner Trustee, Owner Participant or 
Indenture Trustee may bid for and purchase such property.

          Each of Owner Trustee and Indenture Trustee and any Person claiming
through either of them, waives and agrees not to claim any amount under this
Section 5.08(c) or otherwise under this Agreement in respect of incidental or
consequential damages incurred by it.

          To the extent permitted by Applicable Laws, HCG hereby waives any
rights now or hereafter conferred by statute or otherwise that may require Owner
Trustee, its successors or assigns to mitigate its damages in any particular
manner or that may otherwise limit or modify any of the rights or remedies of
Owner Trustee under this Section 5.08(c), but nothing contained herein shall
eliminate Owner Trustee's obligation to mitigate its damages as may be required
by Applicable Law.

          (d)  As used herein, "In-Service Date Force Majeure Event" shall mean
the failure of Owner Trustee and HCG to enter into the Lease on the In-Service
Date for any reason other than in the circumstances described in Section
5.07(b), 5.08(a)(i), 5.08(c) or ll.01 hereof, or Section 2.04 of the Purchase
Agreement.

          (e)  Any payment required under this Section 5.08 to be made by HCG to
Owner Trustee shall be made as if Section 3(f) of the Lease were in effect and
shall be used by Owner Trustee to prepay any and all amounts then due under the
Notes or the Indenture.

          (f)  On the In-Service Date, Owner Participant shall fund in full the
amounts required to be funded by it in Sections 2.06(a) and (b), notwithstanding
the occurrence of any of the events set forth in clause (x), (y) or (z) of
Section 5.08(c).

          (g)  For purposes only of this Section 5.08, to the extent permitted
by, and subject to the mandatory requirements of, Applicable Law, and except as
otherwise specifically provided for in Section 5.08, each and every

right, power and remedy herein specifically given to Owner Trustee or HCG or
otherwise in this Section 5.08 shall be cumulative and shall be in addition to
every other right, power and remedy specifically given in this Section 5.08 or
now or hereafter existing at law, in equity or by statute, and each and every
right, power and remedy whether specifically given in this Section 5.08 or
otherwise existing may be exercised from time to time and as often and in such
order as may be deemed expedient by Owner Trustee or HCG, and the exercise or
the beginning of the exercise of any power or remedy shall not be construed to
be a waiver of the right to exercise at the same time or thereafter any other
right, power or remedy.  No delay or omission by Owner Trustee or HCG in the
exercise of any right, power or remedy or in the pursuit of any remedy shall
impair any such right, remedy or power or be construed to be a waiver of any
default on the part of HCG, Owner Participant or Owner Trustee or to be an
acquiescence therein.  No express or implied waiver by Owner Trustee or HCG of
any such default shall in any way be, or be construed to be, a waiver of any
future or subsequent default.

       SECTION 5.09.  Special Election.  In connection with the possible
                      ----------------                               
occurrence of an event described in Section 5.08(a)(i) or (ii) and in lieu of
the possible prepayment of the outstanding Notes in accordance with Section
5.08(a) and Section 2.7(a)(ix) of the Indenture, Lessee may elect to deliver an
irrevocable written notice to Owner Trustee and Indenture Trustee at least 20
days prior to the first issuance of any Series B Notes to the effect that Lessee
will cause to be delivered an Instruction Certificate with respect to each
Series of Series B Notes to be issued stating that such Series of Notes will
include, in addition to other terms that may be described therein, a term
providing for the prepayment of such Notes, in whole but not in part, with
Premium Amount, or in lieu thereof an election to effect an Exchange of the
Notes pursuant to Section 2.13 of the Indenture.

(except to the extent that any of the items hereinafter described are expressly
made payable by Owner Participant pursuant to Section 9.01), and shall indemnify
and hold harmless each Indemnitee, which, solely

for the purposes of this Article VI, shall include Initial Note Purchaser
(whether or not any of the transactions contemplated hereby shall be
consummated) on an After-Tax Basis from, any and all liabilities, obligations,
losses, damages, reasonable attorneys' fees, penalties, claims, actions, suits,
costs, expenses and disbursements (other than, as to any particular Indemnitee,
any of those specifically provided for in Article VII hereof and the Tax
Indemnification Agreement), including, without limitation, any reasonable
expenses incurred by any Indemnitee in furnishing any reports required pursuant
to the Communications Act or any other provision of Applicable Law with respect
to this Agreement or the transactions contemplated hereby (herein collectively
referred to as "Expenses" and individually as an "Expense") imposed on, incurred
by or asserted against any Indemnitee (whether because of an action or omission
by such Indemnitee or otherwise), in any way relating to or arising out of (i)
any of the Satellite, the earth stations related thereto, or the Transponders or
any part thereof or any interest therein, (ii) the Operative Documents, or the
Hughes Agreements or payments made pursuant thereto or any other transactions
contemplated thereby and (iii) the manufacture, launching, financing, 
refinancing, construction, purchase, acceptance, rejection, delivery,
nondelivery, ownership, acquisition, lease, sublease, preparation, installation,
assembly, storage, maintenance, repair, transportation, abandonment, possession,
repossession, use, operation, condition, sale, return, replacement, redelivery,
modification, transfer of title, rebuilding, rental, importation, exportation or
other application or disposition of all or any part of or any interest in any of
the Transponders or the Satellite or the earth stations related thereto,
including, without limitation, (A) claims or penalties arising from any
violation of law or regulatory requirements of any kind relating solely to
Indemnitee's interest in the Transponders or the Satellite or liability in tort,
strict or otherwise, (B) loss of or damage to any property, the environment or
death or injury to any Person, (C) latent or other defects, whether or not
discoverable, (D) any claim for patent or trademark or copyright infringement,
libel, or slander, including any such claim arising from transmissions to or
from the Satellite or any Transponder, (E) imposition of any Lien (other than
Lessor Liens, with respect to Owner Trustee (and its successors, assigns,

officers, directors, servants, employees and agents)) and (F) claims, penalties
or liabilities in respect thereof based on any other theory of liability. Upon
payment in full of any indemnity pursuant to this Section 6.01, Lessee shall, to
the extent permitted by Applicable Law, be subrogated to any right of such
Indemnitee in respect of the matter against which such indemnity has been paid
to the extent of such payment.  Owner Trustee shall be subrogated to any rights
of Indenture Trustee or the holder of any Note (other than any security
interest) to the extent any amount otherwise payable to Owner Trustee under the
Indenture shall be reduced by the failure of Lessee to have paid any indemnity
to Indenture Trustee or such Noteholder.

          (b)  Without limitation of the foregoing, Lessee shall pay on an 
After-Tax Basis (except to the extent such amounts are payable by Owner
Participant as part of its Commitment, or by Owner Participant pursuant to
Section 9.01 (unless specified otherwise in such Section 9.01)) all the out-of-
pocket costs and expenses (including, without limitation, reasonable legal fees
and expenses) reasonably incurred by Owner Participant, Owner Trustee or
Indenture Trustee in connection with (A) the entering into or giving or
withholding of any future amendments, supplements, waivers or consents (whether
or not they become effective) with respect to any Operative Document or the
Hughes Agreements other than those that are made at the request of such
Indemnitee (unless pursuant to Section 12.06) or in connection with the transfer
of Owner Participant's interest in accordance with Article XIII hereof), (B) the
taking of any action under the Lease or the Indenture at the request of Lessee
or as a result of an Event of Default or (C) any Event of Loss, any redemption,
prepayment or refunding of Notes (including, without limitation, any prepayment,
proposed refunding and refunding contemplated by Section 12.01, whether or not
consummated), in each case as permitted by the terms of the Operative Documents,
subject, in the case of Indenture Trustee to the provisions of the Indenture.

          (c)  If Lessee or any Indemnitee has knowledge of any action, suit,
proceeding or claim hereby indemnified against under this Section 6.01 or any
action, suit, proceeding or claim seeking incidental or consequential damages
against Indemnitee with respect to a Transponder subject to the Lease whether or
not indemnified against under this Section 6.01, it shall give prompt written
notice thereof to the other and Lessee may assume the defense thereof, and, at
such Indemnitee's request, shall assume the defense thereof

                                                                              66

with counsel reasonably acceptable to such Indemnitee. Such Indemnitee shall
fully cooperate with Lessee in all ways reasonably requested by Lessee in said
defense by Lessee.  In any such action, any Indemnitee shall have the right to
employ separate counsel in such action and participate therein, subject to the
preceding sentence, but the fees and expenses of such counsel shall be at the
expense of such Indemnitee, unless (i) the employment of such counsel has been
specifically authorized by Lessee, (ii) the named parties to such action
(including any impleaded parties) include both such Indemnitee and Lessee and
representation of such Indemnitee and Lessee by the same counsel would be
unethical under the applicable standards of professional conduct due to actual
or potential conflicting interests between them or (iii) such action involves an
act that involves or is alleged to involve criminal activity undertaken in
compliance with or as contemplated by the Operative Documents or Hughes
Agreements or involves the risk of criminal penalties, unless such action does
not lead to the commencement (including, without limitation, the impanelling of
a grand jury or similar investigatory proceeding) of a criminal proceeding.
Lessee shall not be liable for any settlement of any action, suit, proceeding or
claim effected without its written consent and no Indemnitee will agree to any
such settlement without the prior written consent of Lessee.

          (d)  Notwithstanding the provisions of the immediately preceding
paragraph, the omission by any Indemnitee to notify Lessee of any Expense shall
not relieve Lessee from any liability which it may have hereunder in respect of
any such Expense or other Expense; provided, however, that nothing herein
                                   --------  -------                   
contained shall prevent Lessee from bringing a subsequent action against such
Indemnitee for damage suffered by Lessee as a result of such omission.

          (e)  If, by reason of any Expense payment made to or for the account
of an Indemnitee by Lessee pursuant to this Section 6.01, such Indemnitee
concurrently or subsequently realizes a tax deduction or credit not previously
taken into account in computing such payment, such Indemnitee shall promptly pay
to Lessee (but only if Lessee shall have made all payments then due and owing to
such Indemnitee under the Operative Documents), an amount equal to the sum of
(i) the actual reduction in Taxes realized by such Indemnitee which is
attributable to such deduction or credit plus (ii) the actual reduction in Taxes
                                         ----                                  
realized by such Indemnitee as a result of any payment made by such Indemnitee
pursuant to this sentence; provided, however,

                                                                              67

that such Indemnitee shall not be obligated to make any payment to Lessee
pursuant to this sentence if and for so long as a Payment Default, Bankruptcy
Default or any Event of Default shall have occurred and be continuing, but shall
promptly make such payment once all such Events of Default shall no longer be
continuing; and provided further, however, that such Indemnitee shall not be
                ----------------  -------                                 
obligated to make any payment pursuant to this Section 6.01 to the extent that
the amount calculated pursuant to (i) above would exceed (x) the amount of all
prior payments received by such Indemnitee from Lessee pursuant to this Section
6.01 with respect to such Expense (determined without regard to any amount paid
in respect of Taxes required to be paid by such Indemnitee in respect of the
receipt or accrual of such amounts) less (y) the portion of all prior payments 
                                    ----       
computed pursuant to (i) above paid by such Indemnitee to Lessee hereunder. Any
Taxes that are imposed on any Indemnitee as a result of a disallowance or
reduction of any tax benefit taken into account in the prior sentence shall be
treated as a Tax for which Lessee is obligated to indemnify such Indemnitee
pursuant to the provisions of Article VII hereof without regard to Section 7.02
(other than subsections (f) and (g) thereof) or Section 7.04 thereof.

          (f)  In the event of a conflict between the provisions of Article 10
of the Purchase Agreement or Article 6 of the Service Agreement and the
provisions of this Agreement, the provisions of this Agreement shall prevail.

          SECTION 6.02.  Exceptions.  The indemnity contained in Section 6.01 
                         -----------                                            
with regard to any particular Indemnitee shall not extend to any Expense (a)
resulting from the willful misconduct or gross negligence of such Indemnitee
(other than willful misconduct or gross negligence imputed to such Indemnitee
solely by reason of its interest in the Transponders) or its respective
corporate successors, officers, directors, servants, agents or employees, (b) to
the extent resulting from the intentional breach by such Indemnitee of any of
its representations, warranties or covenants in any of the Operative Documents
or the Hughes Agreements, (c) to the extent (i) attributable solely to acts or
events occurring after the end of the Lease Term or (ii) resulting from, in the
case of Owner Participant (and its successors, assigns, officers, directors,
servants, employees and agents), an Owner Participant Lien, in the case of Owner
Trustee or Trust Company (and its successors, assigns, officers, directors,
servants, employees and agents), a Lessor's Lien, and in the case of Indenture

Trustee (and its successors, assigns, officers, directors, servants, employees
and agents), an Indenture Trustee's Lien, (d) which is a Tax, it being
understood that all Tax indemnities are governed by the Tax Indemnification
Agreement or Article VII, and it being further understood that this clause (d)
shall not affect any express requirement in the Operative Documents that any
payments otherwise be made on an After-Tax Basis, (e) as to Owner Participant or
Owner Trustee, resulting at any time directly or indirectly from a voluntary
disposition or transfer by Owner Participant or Owner Trustee of all or any part
of its right, title and interest in any of the Transponders or Lessor's Estate
or as to any Indemnitee, resulting at any time from such Indemnitee's voluntary
disposition of all or any part of such Indemnitee's right, title and interest in
and to any of the Transponders or any Operative Document (except that this
clause (e) shall not affect Lessee's obligations under Section 6.01 in respect
of any such disposition following the exercise of remedies under Section 16 of
the Lease in connection with an Event of Default under such Section 16 or in
connection with any disposition under Section 8, 10, 11, 12 or 19 of the Lease
except as otherwise expressly provided in such Sections, (f) expressly required
under any Operative Document to be paid by a party to this Agreement other than
Lessee or as to which Lessee is expressly exempted from liability under any

indirectly, any interest in the Lessor's Estate, the Transponders, or any of the
Operative Documents, (ii) any costs and expenses incurred by Agent for acting as
agent of Owner Participant and (iii) any obligation of Agent under the
Reoptimization Agreement.
 
          Except as expressly provided in this Agreement or in any other
Operative Document, Lessee shall not be liable to any Indemnitee for incidental
or consequential damages suffered by such Indemnitee; provided, however, that
                                                      --------  -------
the foregoing shall not be construed to limit recovery by any Indemnitee of any
costs, expenses or liabilities incurred by such Indemnitee as a result of any
third party claim against such Indemnitee based on events occurring and/or
conditions existing any time prior to the expiration or earlier termination of
the Lease, except to the extent incurred by such Indemnitee as a result of
affirmative actions of such Indemnitee to market or otherwise utilize any
Transponders; provided, however, that nothing in this exception shall modify or
              --------  -------
limit Lessor's remedies under Section 16 of the Lease.

          With respect to any amount which Lessee is requested by an Indemnitee
to pay by reason of this Article VI, the Indemnitee shall, if requested by
Lessee and prior to any payment, submit such additional information to Lessee as
Lessee may reasonably request properly to substantiate the requested payment.
Lessee covenants and agrees to pay all amounts due under this Article VI
promptly and in any event within 30 days of demand. Nothing contained in this
Article VI shall increase, decrease or otherwise affect in any way Seller's or
Hughes Services' obligations under the Hughes Agreements in their respective
capacities as Seller and service provider thereunder.

government or any taxing authority thereof in the United States or any territory
or possession of the United States or by any foreign government, taxing
authority or governmental subdivision of a foreign country or international
taxing authority, and if any such withholding is required, Lessee shall pay an
additional amount of Rent such that the net amount of Rent actually received by
an Indemnitee will be equal to the amount of Rent that would then be due absent
such withholding. Any withholding tax paid by Lessee that is excluded from this
Section 7.01 by Section 7.02 shall be promptly repaid to Lessee by the
appropriate Indemnitee.

          Except as provided in Section 7.02, whether or not the transactions
contemplated by the Operative Documents are consummated, Lessee hereby assumes
liability for and agrees to timely pay, and on written demand shall indemnify,
defend and hold each Indemnitee harmless, on an After-Tax-Basis, from and
against any and all Taxes actually imposed on or with respect to any Indemnitee,
Lessee, any Transponder or any part thereof or any interest therein, the
Satellite, or otherwise by any Federal, state or local government or any taxing

      failure properly to file returns or statements, whether related or
      unrelated to the transactions contemplated by the Operative Documents or
      the Hughes Agreements (unless such failure results from Lessee's failure
      to provide timely notice of the requirement of such filing or the failure

     Agreements (other than such a default that results from a default by

     this exception shall not apply in the event that such sale, transfer,
     assignment or other disposition shall occur as the result of any acts
     pursuant to Sections 7, 8, 12, 16 or 19 of the Lease or at any time while
     an Event of Default, Payment Default or Bankruptcy Default shall have

     Indemnitee had it not engaged in activities related to the transaction

                                                                              74

Notwithstanding anything to the contrary contained in this Section 7.02, the
exceptions set forth in this Section 7.02 shall not apply, with respect to Owner
Trustee, Owner Participant or the Lessor's Estate, to any Taxes imposed by way
of withholding on payments of principal, interest or premium on the Notes or
imposed by reason of any failure to withhold with respect to such payments.
 
       SECTION 7.03. Calculation of Indemnity Payments. If any Indemnitee
                     ----------------------------------
subsequently realizes a tax benefit by reason of any payment of an indemnified
Tax pursuant to this Article VII or by reason of payment of an amount, which
amount was reimbursed to such Indemnitee by Lessee on an After-Tax Basis
pursuant to a provision specifically requiring the payment of such amount on an
After-Tax Basis (other than pursuant to any provision of Article VI or the Tax
Indemnification Agreement), which benefit had not previously been taken into
account in computing such payment, such Indemnitee shall pay Lessee when such
tax benefit is actually utilized (but not before Lessee shall have made all
payments and indemnification theretofore due to such Indemnitee pursuant to the
Operative Documents) an amount equal to the lesser of (a) the sum of (i) an
amount equal to such tax benefit, plus (ii) an amount equal to any other tax
benefit realized and actually utilized by such Indemnitee as the result of any
payment made by such Indemnitee pursuant to this sentence, and (b) the amount of
such payment and any other payment by Lessee to such Indemnitee with respect to
the Tax or other amount that gave rise to such tax benefit, reduced by other
amounts previously paid by such Indemnitee to Lessee with respect to the tax
benefits resulting from such Tax or other amount pursuant to this Article VII;
provided, however, that, notwithstanding the foregoing portions of this
- --------  ------- 
sentence, such Indemnitee shall not be obligated to make any payment to Lessee
pursuant to this sentence if and for so long as an Event of Default shall have
occurred and be continuing, but shall promptly make such payment once all Events
of Default shall no longer be continuing. Any Taxes that are imposed on any
Indemnitee as a result of a disallowance or reduction of any tax benefit taken
into account in the prior sentence shall be treated as a Tax for which Lessee is
obligated to indemnify such Indemnitee pursuant to the provisions of Article VII
hereof without regard to Section 7.02 (other than subsections (c), (d), (e),
(f), (g), (h) and (i) thereof).
 
       SECTION 7.04. Contest. (a) If a claim shall be made against any
                     -------
 Indemnitee for any Tax in excess of $10,000
 
<PAGE>
 
                                                                              75

for which Lessee would be obligated to indemnify pursuant to this Article VII,
such Indemnitee shall promptly notify Lessee after such Indemnitee becomes aware
of such action and in any event within 30 days after receipt by such Indemnitee
of a written claim (but failure to notify Lessee within such 30-day period shall
not impair such Indemnitee's right to indemnification under this Article VII
except to the extent that Lessee's rights to contest such claim shall have been
materially impaired by such failure) and shall, to the extent permitted by
applicable law, not pay the claim before the earlier of (i) 30 days after giving
Lessee notice and (ii) receipt of Lessee's response. If Lessee shall so request
within the period referred to in the foregoing sentence, such Indemnitee shall,
at Lessee's expense reimbursed to such Indemnitee on an After-Tax Basis, contest
the imposition, validity or applicability of such Tax. The ultimate control over
the conduct of such contest (including the right to forgo any and all
administrative appeals, proceedings, hearings and conferences in respect of such
claim and the right to select the forum for such contest and determine whether
any such contest shall be by (i) resisting payment of such Tax, (ii) paying such
Tax under protest or (iii) paying such Tax and seeking a refund thereof) shall
remain with such Indemnitee; provided, however, that such Indemnitee shall keep
                             --------- --------
Lessee or its counsel reasonably informed as to the progress thereof, consult
with Lessee within a reasonable period before any significant action with
respect thereto is taken or omitted and consider in good faith any suggestions
made by Lessee or its counsel; provided further that unless (a) remedies under
                               ----------------
Section 16 of the Lease shall have been, or are being, exercised in connection
with an Event of Default which has occurred and is continuing or (b) a
Bankruptcy Default or Payment Default has occurred and is continuing, and
subject to Indemnitee's waiver rights described in Section 7.04(b) hereof, and
provided that all conditions set forth in this Section 7.04 for the continuation
of a contest shall then be satisfied, no such proceedings or litigation shall be
settled or otherwise compromised without the prior written consent of Lessee. If
such Indemnitee so elects, such contest shall be conducted by Lessee in the name
of such Indemnitee (subject to the preceding proviso) and in no event shall such
Indemnitee be required or Lessee be permitted to contest or to continue to
contest, as the case may be, the imposition of any Tax for which Lessee is
obligated to indemnify pursuant to this Article VII unless (A) Lessee shall have
agreed to pay such Indemnitee on demand and shall have paid as so demanded all
reasonable costs and expenses that such Indemnitee may incur in connection with
contesting such

                                                                              76

claim (including, without limitation, all costs, expenses, losses, reasonable
legal and accounting fees and disbursements) on an After-Tax Basis, (B) Owner
Participant shall have determined in good faith that the action to be taken will
not result in any material risk of a Lien on, or of sale, forfeiture or loss of
any Transponder or any part thereof or any interest therein (except if Lessee
shall have made provision to protect the interests of Owner Participant in a
manner satisfactory to Owner Participant), (C) if such contest shall be
conducted in a manner requiring the payment of the claim, Lessee shall have
advanced on an interest-free basis an amount equal to the amount of such claim
which such Indemnitee shall have elected to pay and Lessee shall have
indemnified the Indemnitee in a manner satisfactory to the Indemnitee, for any
adverse tax consequences from the receipt, or interest-free nature, of such
advance and (D) an Event of Default, Payment Default or Bankruptcy Default shall
not have occurred and be continuing unless Lessee has posted adequate security
securing payment of the Tax subject to the contest and expenses of the contest
in a manner reasonably acceptable to such Indemnitee.

          (b) An Indemnitee may at any time elect to settle or compromise any
proposed claim or contest or decline to take any action or any further action
with respect to a proposed claim or contest; provided, however, that if Lessee
                                             --------- --------              
has properly requested such action pursuant to this Article VII and has
satisfied all conditions set forth in Section 7.04(a) for the continuation of a
contest, such Indemnitee shall notify Lessee that it waives its right to any
indemnity payment by Lessee that would otherwise be payable by Lessee pursuant
to this Article VII in respect of such claim. An election by an Indemnitee to
settle or compromise any proposed claim or contest or decline to take any action
or take any further action with respect to a proposed claim or contest for any
given taxable period shall not affect the rights and obligations of any other
Indemnitee with respect to such proposed claim. An election by an Indemnitee to
settle or compromise any proposed claim or contest or decline to take any action
with respect to a proposed claim or contest (under circumstances where Lessee
shall have properly requested action and satisfied all conditions for the
continuation of a contest set forth in Section 7.04(a)) shall not affect the
rights and obligations of such Indemnitee and Lessee hereunder in respect of any
other taxable period or any other taxing authority except to the extent such
election not to contest materially impairs as a legal or practical matter the
ability of Lessee or an Indemnitee to contest any Tax with respect to such other
<PAGE>
 
                                                                              77

taxable period or such other taxing authority for which such Indemnitee is
indemnified pursuant to this Article VII. Upon any such election by an
Indemnitee, if Lessee shall have advanced an amount to an Indemnitee pursuant to
clause (C) of Section 7.04(a), such Indemnitee shall repay the advance to
Lessee, plus interest on such advance from the date of the making of such
advance by Lessee to the day next preceding the day of repayment of such advance
by such Indemnitee calculated at the applicable rate of the tax authority with
respect to the claim to which the advance related; such repayment shall be made
upon the occurrence of the earlier of (x) final adjudication of such contest
(including a settlement thereof) and (y) such time as such Indemnitee shall
elect to discontinue the contest as above provided; provided, however,
                                                    --------  ------- 
notwithstanding the foregoing, such Indemnitee shall not be obligated to make
any repayment to Lessee pursuant to this sentence for so long as an Event of
Default shall have occurred and be continuing but shall promptly make such
payment once all Events of Default shall no longer be continuing.

          SECTION 7.05. Reports. If any report, return or statement is required
                        --------                                              
to be filed with respect to any Tax which is subject to indemnification under
this Article VII, Lessee shall promptly notify the appropriate Indemnitee of
such requirement and shall timely file the same, except for any such report,
return or statement which an Indemnitee has notified Lessee that such Indemnitee
intends to file; provided, however, prior to the filing by any Indemnitee of
                 --------  -------                                        
any report, return or statement in respect of which an amount greater than
$10,000 is required to be paid by Lessee, such Indemnitee shall notify Lessee
that such report, return or statement and such Tax is due and such notification
shall be within a reasonable amount of time to enable Lessee to contest such
Tax, and, with respect to any report, return or statement being filed by Lessee,
the Indemnitee shall at Lessee's expense be required to provide Lessee on a
timely basis with any information reasonably requested, provided further, that,
                                                        -------- -------     
without prejudice to any other rights Lessee may have in connection therewith
(including, without limitation, any claim for damages for a failure to give the
notice or reasonably requested information pursuant to this Section 7.05), the
failure to provide any such notice or reasonably requested information shall not
affect Lessee's obligations hereunder to any Indemnitee unless such failure
shall materially impair a contest of such Tax. Lessee shall either file such
report, return or statement so as to show the ownership of the Transponders in
Owner Trustee and send a copy of such

                                                                              78

report, return or statement to Owner Trustee or, where not so permitted, 
promptly notify Owner Participant of such requirement and prepare and deliver 
such report, return or statement to Owner Participant in a manner satisfactory 
to Owner Participant within a reasonable time prior to the time such report, 
return or statement is to be filed.

     SECTION 7.06. Payment. (a) Unless otherwise requested by the appropriate 
                   --------
Indemnitee, Lessee shall pay any Tax for which it is liable pursuant to this
Article VII directly to the appropriate taxing authority when due and, if so
otherwise requested, shall pay such appropriate Indemnitee within 15 days after
demand, in immediately available funds, any amount due such Indemnitee pursuant
to this Article VII with respect to such Tax or such payment, but not prior to
the later of (i) payment of such Tax and (ii) final adjudication (including
settlement consented to by Lessee) in the case of a contest pursuant to Section
7.04. Any such demand shall specify in reasonable detail the payment and the
facts upon which the right to payment is based. Each Indemnitee shall promptly
forward to Lessee any notice, bill or advice received by it concerning any Tax
for which such Indemnitee claims indemnification hereunder. Within 30 days after
the date of each payment by Lessee of any Tax, Lessee shall furnish the
appropriate Indemnitee with the original or a certified copy of a receipt for
Lessee's payment of such Tax or such other evidence of payment of such Tax as is
acceptable to such Indemnitee. Lessee shall also furnish promptly upon request
such data as any Indemnitee may require to enable such Indemnitee to comply with
the requirements of any taxing jurisdiction.

     (b) Lessee agrees that it shall have no right to inspect the books, 
records, tax returns or any other document of such Indemnitee or any Affiliate 
thereof in order to verify the basis or accuracy of the calculations made 
pursuant to this Article VII; provided, however, within 10 days following 
                              --------  -------
Lessee's receipt of any notice or demand involving calculations to be made 
pursuant this Article VII, Lessee may request that the correctness of such 
calculations be verified (but such verification shall be limited to calculations
and shall not extend to any interpretation of the scope of any indemnity 
provision or the existence of a liability hereunder), at Lessee's expense, by 
one of the six largest United States public accounting firms selected by the 
relevant Indemnitee and approved by Lessee, which approval will not be 
unreasonably withheld, and such Indemnitee shall deliver to Lessee a

certificate of a senior officer together with a statement from such public
accounting firm confirming that the calculations set forth in or supporting the
amount set forth in such notice or demand to which such request relates have
been verified as above provided and that the calculations are accurate and in
conformity with the provisions of this Article VII. The assumptions, the method
of calculation and the other information revealed or made available to such
accounting firm shall be kept confidential and shall not be revealed by it to
any other Person.

                        --------------------------------                      
for which an Indemnitee claims indemnification hereunder that is reported on a
consolidated or combined basis by such Indemnitee, the rules applicable to the
consolidated or combined return of the Indemnitee shall be taken into account in
computing the amount of any indemnity or payment by or to Lessee under this
Article VII in respect of such Tax.

                        ----------------------------                          
the indemnities provided for in this Agreement shall be those of primary
obligor, whether or not the Person indemnified shall also be indemnified with
respect to the same matter under the terms of any of the other Operative
Documents, the Hughes Agreements or any other document or instrument, and the
Person seeking indemnification from Lessee pursuant to any provisions of this
Agreement may proceed directly against Lessee (subject to the provisions of this
Agreement) without first seeking to enforce any other rights of indemnification.

          SECTION 8.02. Payments and Survival of Indemnities. Unless otherwise

specifically provided for herein, all amounts payable by Lessee pursuant to
Articles VI and VII shall be payable directly to the Person entitled to payment

the indemnities of the parties hereunder shall survive the termination of this
Agreement and the other Operative Documents and shall survive the transfer of
any Note or any interest of Owner Participant in Lessor's Estate and the payment
of any or all of the Notes.

Service Date, as the case may be (subject to paragraph (b) of this Section
9.01), pay when due, or reimburse Lessee upon request, for, all such Transaction
Costs not theretofore paid by Owner Trustee. Owner Participant agrees to provide
to Owner Trustee funds to pay Transaction Costs payable by Owner Trustee

Costs paid by Lessee prior to the Closing Date, if any, will be reimbursed on

such refinancing.  If the transactions contemplated by this Agreement to be
consummated on the Closing Date are not consummated, Lessee shall pay when due
all Transaction Costs accrued to such failed Closing Date, the payment of which
is otherwise the obligation of Owner Trustee pursuant to the first sentence of
this Section 9.01(a); provided, however, that if such transactions shall not be
                      --------  -------                                      
consummated by reason of a breach by Owner Trustee or Owner Participant of its
obligations hereunder or under any other Operative Document or Hughes Agreement
to which such Person is or will be a party, or, in the case of Owner Participant
if it shall have become a Defaulting Participant, Lessee shall not be obligated
to pay the Transaction Costs incurred by such Person.

          (b)  To the extent any Transaction Costs, when combined with the other
amounts actually funded by Owner Participant pursuant to Sections 2.01(b) and
2.12(b), would exceed the Equity Cap, such Transaction Costs will be paid by
Lessee or, at Lessee's election, reimbursed to Owner Trustee as a payment of
Supplemental Rent, in any case on an After-Tax Basis.

          (c)  Each of the Transaction Costs and each of the expenses incurred
after the Closing Date or referred to in Section 9.02 shall be evidenced by
appropriate bills or invoices.  HCG shall have the right to (i) receive any
substantiation relating to any such Transaction Costs or ongoing expenses as HCG
may reasonably request and (ii) reasonably approve (which approval shall not be
unreasonably withheld or delayed) within 30 days of notice thereof the payment
thereof prior to such payment by Owner Trustee.

                         ---------------------------------------               
will pay all costs and expenses incurred in connection with the entering into or
the giving or withholding of any future amendments, supplements, waivers or
consents with respect to the Operative Documents or the Hughes Agreements in
accordance with the provisions of Section 6.01(b) hereof (whether or not such
amendments, supplements, waivers or consents become effective).

          (b)  Lessee shall pay the reasonable fees and expenses of Owner
Trustee (including without limitation expenses in connection with the
preparation and filing of any reports and tax returns (other than incremental
costs attributable to the existence of more than one Owner Participant)),
Indenture Trustee and each Pass Through Trustee, if

          SECTION 10.01.  Series A Notes and Series D Notes.  (a)(i) HCG and 
                          ---------------------------------                   
each of Owner Participant, Initial Note Purchaser, Owner Trustee and Indenture
Trustee agree to cooperate to effect the refinancing in full of the Series A
Notes described in this Article X and to negotiate in good faith to conclude
such additional agreements and such supplements or amendments to or consents or
waivers under each of the Operative Documents as may be reasonably requested by
HCG to effect the transactions contemplated in connection with such refinancing,
in compliance with and subject to the terms and conditions of this Article X
including, without limitation, any amendment or supplement to the Indenture that
may be reasonably necessary to allow the Series B Notes, the Series C Notes, the
Series E Notes, the Series F Notes and/or the Series G Notes to take the form of
public, private institutional or commercial bank debt, and will negotiate in
good faith to resolve any resulting debt/equity points in a manner reasonably
satisfactory to Owner Participant, HCG and the proposed holders of any such debt
and in a manner reflecting then current market terms for public or private debt,
as applicable, in leveraged leases, recognizing that the manner in which
debt/equity points are resolved in a private institutional or commercial bank
debt transaction may, at the time that such Series of Notes is to be issued, be
less favorable in certain respects to Owner Participant than the manner in which
such debt/equity points shall have been resolved in the Indenture at the date
hereof, all subject to the terms and conditions of this Article X.

          (ii)   From and after July 2, 1993, the interest rate on any
outstanding Notes (other than the Series A Notes) shall be fixed. Any Series G
Notes issued by Owner Trustee shall have the same amortization schedule as the
refunded Series A Notes and a final maturity as early as the fifth anniversary
of issuance.  The terms (financial or otherwise) of the Series G Notes shall
reflect then current market terms for commercial bank loans in a leveraged lease

                                                                              83

context to borrowers similarly situated to HCG, taking into account the
guarantee of GMHE, the credit standards of the lender and the fixed rate feature
and maturity date of the Series G Notes, and the Indenture shall be modified, if
necessary, including without limitation with respect to debt/equity points, to
reflect such market terms.

          (iii)  HCG shall use reasonable best efforts to arrange the issuance
of the Series B Notes to refinance the Series A Notes; provided, however, that
                                                       --------  -------
if HCG delivers an Officer's Certificate to Owner Participant and Owner Trustee
to the effect that it has used such reasonable best efforts but has been unable
to arrange such a refinancing, HCG may arrange for the issuance of Series G
Notes to refinance the Series A Notes or pursue any of the other options
available to it under this Section 10.01; provided further, however, that no
                                          ----------------  -------
Series G Notes may be issued prior to April 1, 1993.

          (iv)   If at the maturity date of any Series F Note or Series G Note
such Note shall not be refinanced with the proceeds of Series B Notes, on such
maturity date Lessee shall pay to Owner Trustee as Supplemental Rent, on an
After-Tax Basis, the amount necessary to redeem in full such Series F Note or
Series G Note and Owner Trustee shall effect such redemption on such date with
such amount.

          (b)    Subject to Section 10.02, on or prior to the earlier of (i) 30
days following the launch of Galaxy VII and (ii) December 1, 1992 (the earlier
of such dates being referred to herein as the "Mandatory Refinancing Date"), HCG
shall arrange for (x) the Series A Notes to be refunded in full with the
proceeds of the sale of the Series B Notes and the Series C Notes and (y) the
Series D Notes to be refunded in full with the proceeds of the sale of the
Series E Notes (the "Mandatory Refinancing").  If such refinancings are arranged
by HCG, then, subject to Section 10.01(a), Owner Trustee agrees to issue and
sell such Series B Notes, Series C Notes and Series E Notes to purchasers
selected by or on behalf of HCG who are reasonably satisfactory to Agent and who
are not Affiliates of HCG.  The date on which the Series A Notes are refinanced
with the proceeds of the sale of Series B Notes and, if applicable, Series C
Notes (whether occurring on, or prior or subsequent to, December 1, 1992) is
referred to herein as the "Debt Refinancing Date".  Not less than 10 days prior
to the Mandatory Refinancing Date, HCG shall deliver to Agent a written notice
describing the proposed arrangements, if any, for the refinancing to occur on
such date.

          (c)  Subject to Sections 10.01(f) and 10.02, if HCG shall be unable to
arrange the Mandatory Refinancing on or prior to December 1, 1992, then HCG
shall deliver to Agent a written notice to that effect on or prior to December
1, 1992, in which case Agent, on behalf of Owner Participant and the Other Owner
Participants, shall have the right but not the obligation to arrange a
refinancing of the Series A Notes and the Series D Notes and the Other Notes
similar to the Series A Notes and the Series D Notes outstanding relating to the
Other Transponders; provided that (i) the terms and conditions of any such
                    --------                                             
refinancing of such Notes and Other Notes arranged by Agent shall be
substantially similar to the terms and conditions obtainable in the relevant
market for financings having similar credit support and of similar principal
amount and maturity, and (ii) subject to Section 10.01(d)(iii), no such
refinancing arranged by Agent may occur (x) on any day other than the In-Service
Date or (y) if HCG exercises its rental adjustment purchase option under Section
11.01.

          (d)  Subject to Sections 10.01(f) and 10.02, if the refinancing of the
Series A Notes shall not have occurred on or prior to the In-Service Date, then,
during the period commencing on the day following the In-Service Date and ending
on June 30, 1993, Agent may (but shall not be obligated to) arrange the
refinancing of the Series A Notes and the Other Notes similar to the Series A
Notes outstanding relating to the Other Transponders; provided that (i) such
                                                      --------             
refinancing is reasonably satisfactory to HCG, (ii) such refinancing may not be
arranged in the public market and (iii) such refinancing may not occur on a date
other than June 30, 1993.

          (e)  In the case of a refinancing under Section 10.01(c) or 10.01(d),
if all of the conditions to such refinancing set forth in the proviso to Section
10.01(c) or 10.01(d), as applicable, are satisfied, the refinancing so arranged
by Agent shall constitute a Mandatory Refinancing.  If such a Mandatory
Refinancing fully refinanced the Series A Notes and (in the case of Section
10.01(c)) the Series D Notes, the reasonable costs and expenses incurred by
Agent and Owner Participant or any other Person in connection with Agent's
arranging such Mandatory Refinancing (pro-rated based upon the aggregate
Lessor's Cost for the Transponders and the Other Transponders) shall constitute
Transaction Costs; if not, then none of such costs and expenses shall constitute
Transaction Costs but the same shall be borne solely by the Owner Participant
and the Other Owner Participants

                                                                              85

(pro-rated as aforesaid) and none of Agent, Owner Participant, Owner Trustee,
Indenture Trustee and any other Person shall have any direct or indirect
recourse to HCG or any of its Affiliates with respect thereto.

          (f)  The provisions of Section 10.01(c) and 10.01(d) shall not in any
way preclude HCG from continuing to have the opportunity to arrange the
refinancing of the Series A Notes and the Series D Notes from and after the
Mandatory Refinancing Date if the Mandatory Refinancing shall not have been
consummated by that date, provided that, after the In-Service Date, the
provisions of Section 10.02 shall apply.  So long as HCG continues actively to
seek to arrange such a refinancing, and keeps Agent informed as to the status of
HCG's refinancing efforts, Agent, Owner Participant and Owner Trustee shall
cooperate with HCG so as to permit HCG to successfully complete its own
refinancing.  Agent shall keep HCG informed of all steps Agent proposes to take
to arrange either of the refinancings contemplated by Sections 10.01(c) and
10.01(d), and the status thereof.

          (g)  Subject to clause (ii) of the proviso to Section 10.01(d), each
party agrees that the Mandatory Refinancing described in Section 10.01 or other
refinancing of the Series A Notes may be effected pursuant to one or more public
offerings or private placements (including, without limitation, an institutional
private offering qualifying for resale under Rule 144A under the Securities Act)
and may involve a pass-through structure, in all cases on terms and conditions
reasonably satisfactory to HCG and Agent.

          SECTION 10.02.  Failure to Arrange Mandatory Refinancing.  (a) HCG
                          ----------------------------------------       
shall not be liable to any Person if the refinancing of the Series A Notes or
the Series D Notes does not occur on or prior to the In-Service Date, but in
such event (i) the Series D Notes shall remain outstanding until the In-Service
Date and (ii) the portion of the principal amount of each Series A Note
(including accrued interest thereon) equal to the Debt Commitment (as determined
on the In-Service Date) for the related Transponder shall remain outstanding
after the In-Service Date until the final maturity thereof or, if earlier, the
date such Series A Notes are refinanced.  After the In-Service Date, Lessee
shall be permitted to refinance the outstanding Series A Notes at any time on
terms reasonably satisfactory to Agent, and Owner Participant shall have the
right to arrange the refinancing of the outstanding Series A Notes as provided
in Section 10.01(d), it being agreed that any such refinancing effected by
Lessee may take the form of

                                                                              86

floating rate commercial bank debt on terms reasonably satisfactory to Agent
through the issuance of one or more Series G Notes; provided, however, that if
                                                    --------  -------       
the Series A Notes shall not have been refinanced in full on or prior to June
30, 1993, then, unless Owner Participant shall have otherwise agreed in writing,
the Tax Indemnification Agreement shall be deemed to be amended by the
provisions attached hereto as Exhibit Q; provided further, however, that if
                                         ----------------  -------
Lessee elects, by notice delivered to Owner Trustee and Owner Participant on or
prior to July 1, 1993, to purchase all but not less than all the Transponders as
provided in Section 19(a)(vi) of the Lease, then the Tax Indemnification
Agreement shall not be so amended.

          (b)  Notwithstanding anything to the contrary contained herein, if
Initial Note Purchaser or its Affiliate(s) shall hold any Series A Notes after
December 1, 1992, then until such time as the Series A Notes shall have been
refinanced in full, and provided that Owner Participant has fully funded all
amounts required to be funded by it pursuant to Sections 2.06(a) and (b) and the
Deferred Equity Amount when due pursuant to Section 2.12, then, as provided in
the Indenture, (i) upon the occurrence and during the continuance of a Lease
Event of Default, Initial Note Purchaser or its Affiliate(s) as Noteholders
shall not be entitled to exercise the rights or remedies referred to in, and
subject to, Section 5.11 of the Indenture, but Owner Trustee shall be entitled
to exercise unilaterally such rights and remedies under the Lease to the extent
therein specified, and (ii) any distribution received by Indenture Trustee from
Lessee (if such amounts are less than those required to be paid by Lessee
pursuant to the Lease) and otherwise payable to Initial Note Purchaser or its
Affiliate(s) as holders of the Series A Notes shall be subordinated in right of
payment to distributions then due, if any, to Owner Trustee, as specified in
Section 5.11 of the Indenture.

          SECTION 10.03.  Series B Notes and Series C Notes.  (a) The principal
                          ---------------------------------                 
amount of Series B Notes to be issued on the Debt Refinancing Date will equal
such amount which, when added to the interest anticipated to accrue thereon from
the Debt Refinancing Date to the then anticipated In-Service Date, determined in
the reasonable judgment of HCG, will be equal to the Debt Commitment (as of the
anticipated In-Service Date).  The proceeds of the sale of the Series B Notes or
Series G Notes will be used to refund in part the Series A Notes (including
payment of accrued interest thereon).

                                                                              87

          (b)  If the Debt Refinancing Date occurs prior to the In-Service Date,
then on the Debt Refinancing Date, Series C Notes will be issued and sold in a
principal amount which is equal to the amount required to refund in full the
Series A Notes (including accrued interest thereon) on the Debt Refinancing
Date, after application to such refunding of the proceeds from the sale of the
Series B Notes as provided above in Section 10.03(a).

          (c)  The Series G Notes may be refinanced with the proceeds of Series
B Notes pursuant to Section 2.3(a)(ii) of the Indenture.  In connection with any
such refinancing, the terms (financial or otherwise) of the Series B Notes used
to refinance the Series G Notes shall reflect then current market terms for the
type of indebtedness (which may include commercial bank debt) and lender
involved, in a leveraged lease context, with borrowers similarly situated to
HCG, taking into account the guarantee of GMHE, the credit standards of the
lender and the fixed rate feature and maturity date of the Series B Notes, and
the Indenture shall be modified, if necessary, including without limitation with
respect to debt/equity points, to reflect such market terms.

                          ----------------------------------------------   
participation by Owner Participant and Owner Trustee in any refinancing of the
Series A Notes shall be subject to the satisfaction of, or waiver by, Owner
Participant and Owner Trustee of the following additional conditions:

          (a)  [Intentionally Omitted]

          (b)  the Factors shall be adjusted as provided in and in accordance
     with Section 12.05(c) or 12.06, 12.07 and 12.08, as applicable;

          (c)  each of Agent, on behalf of Owner Participant, and Owner Trustee
     shall have received (i) such opinions of counsel as they may reasonably
     request concerning compliance with the Securities Act and any other
     Applicable Law relating to the sale of securities and (ii) such other
     customary opinions of counsel as they may reasonably request and, in
     connection with compliance with the terms and conditions of this Article X,
     such certificates and other documents as they may reasonably request, in
     each case in form and substance reasonably satisfactory to each of them;

terms and conditions of any debt arranged by Agent as part of a proposed
refunding of the Series A Notes pursuant to Article X are not reasonably
satisfactory to HCG or (ii) the aggregate of all rental adjustments, if any,
which occur with respect to the Lease from and after July 15, 1992, to and
including the In-Service Date shall result in (A) an increase in the present
value of Scheduled Rent (through the EBO Date) and the EBO Amount (in each case
discounted to the In-Service Date at the Discount Rate) as compared to the
present value set forth in Exhibit G to Schedule III, of more than 2% of
Lessor's Cost or (B) the Lease's not qualifying as an Operating Lease for
Lessee, HCG shall have the right, by providing each other party hereto with
irrevocable written notice thereof on the date that, but for the next succeeding
sentence would have been the In-Service Date, to purchase, on the Business Day
first occurring on or after the 30th day following such notice, all (but not
less than all) the Transponders for the higher of (x) Lessor's Cost thereof on
the date that, but for the next succeeding sentence would have been the In-
Service Date (offset by an amount equal to the amount, if any, that would have
otherwise been required to be paid by Owner Trustee to Seller on the In-Service
Date pursuant to Section 2.06(a) or 2.08(b) as an upward adjustment to the
purchase price in the event that such purchase option had not been exercised)
and (y) Special Termination Value.  Notwithstanding anything to the contrary
contained herein, if the option contained in this Section 11.01 is exercised,
the In-Service Date shall be deemed not to have occurred for purposes of this
Agreement.

          (b)  On the repurchase date specified in paragraph (a) above, upon the
receipt of the option price described therein, Owner Trustee shall transfer all
its right, title and interest to the Transponders, as is and where is, to HCG,
free and clear of Lessor Liens and Owner Participant Liens but otherwise without
warranty, and Owner Trustee shall execute and deliver to HCG, at HCG's
reasonable expense, a bill of sale or assignment and such other instruments,

action under Section 10 of the Indenture as HCG may reasonably request.

pursuant to Section 5.08 or 11.01 hereof or Section 19(a)(ii), (iii), (v) or

exercising such right may elect to purchase the right, title and interest of
Owner Participant in and to Lessor's Estate (the "Beneficial Interest") at a
purchase price equal to (i) in the case of any purchase pursuant to Section
19(a)(ii) of the Lease, the aggregate EBO Amounts for all such Transponders,

applicable Rent Payment Date and (b) the Fair Market Sales Value of all of such
Transponders as of such Rent Payment Date, (iii) in the case of a purchase
pursuant to Section 19(a)(v) of the Lease, the greater of (a) the Fair Market
Sales Value of all the Transponders on the applicable Rent Payment Date (offset,
in the event such Fair Market Sales Value is greater than the fair market value
of all Transponders set forth in the In-Service Date Appraisal, by an amount
equal to the excess of (y) the actual Fair Market Sales Value of such
Transponders on the In-Service Date, as determined by an appraisal obtained in
accordance with Section 19(b)(ii) of the Lease, which appraisal shall take
into consideration all factors and conditions existing on the In-Service Date
that were not taken into account in the determination of fair market value set
forth in the In-Service Date Appraisal over (z) Lessor's Cost for such
Transponders set forth in the In-Service Date Appraisal) and (b) Termination
Value for such Transponders on such Rent Payment Date, (iv) in the case of a
purchase pursuant to Section 19(a)(vi) of the Lease, the greater of (a) the Fair
Market Sales Value on August 31, 1993 and (b) Termination Value on such date,

Lessee shall, if it desires to exercise its right to purchase the Beneficial
Interest pursuant to Section 11.02, give irrevocable notice to each other party

the date of purchase is a Rent Payment Date on which a Scheduled Rent payment
designated as an "arrears rent" on Schedule A is due, upon receipt by Lessor of
all such Scheduled Rent designated as "arrears rent" due on such Rent Payment
Date as set forth on Schedule A to the Lease, and the Rent Differential Amount,
if any, and all other Supplemental Rent due by Lessee on such Rent Payment Date
to or distributable to Owner Participant to and including such date of purchase
(without giving effect to any applicable grace periods), Owner Trustee shall
distribute to Owner Participant all such amounts received by it and all other
cash then held by it (other than cash distributable to Owner Trustee in its
individual capacity), and immediately thereafter Owner Participant shall
transfer the Beneficial Interest free and clear of all Owner Participant's Liens
to Lessee pursuant to an instrument of conveyance in form and substance
reasonably satisfactory to Lessee; provided that Owner Participant shall have
                                   --------                                 
been released from any obligations under the Operative Documents arising after
such purchase except to the extent that such obligations are attributable to
events or circumstances occurring prior to the purchase of the Beneficial
Interest by Lessee.

          (c)  Each of Owner Participant, Owner Trustee, and Indenture Trustee
at the cost and expense of Lessee and on an After-Tax Basis, will cause to be
promptly and duly taken, executed, acknowledged and delivered all such further
acts, documents and assurances as Lessee reasonably may request in order to
carry out the intent and purpose of this Article XI and the transactions
contemplated hereby.

          (d)  As a condition to Lessee's right to purchase the Beneficial
Interest pursuant to Section 11.02 (unless there shall occur an Exchange Event
with respect to the
<PAGE>
 
                                                                              91

obligations of Owner Trustee pursuant to the next sentence), on the date of
purchase Lessee shall have provided to Indenture Trustee and Owner Trustee an
opinion of counsel for Lessee, dated the date of purchase, which, subject to
usual or customary exceptions, shall be to the effect that, upon consummation of
such purchase, this Agreement, the Trust Agreement, the Lease and, in the case
of GMHE, the Guaranty Agreement constitutes the legal, valid and binding
obligation of Lessee or, in the case of the Guaranty Agreement, GMHE,
enforceable against Lessee or GMHE, as applicable in accordance with its terms
except as the same may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the rights of creditors
generally and by general principles of equity, and except as limited by
applicable laws that may affect the remedies provided for in the Lease, which
laws, however, do not in the opinion of such counsel make the remedies provided
for in the Lease inadequate for the practical realization of the rights and
benefits provided for in the Lease. In the event Lessee is unable to provide
such opinion, concurrently with the purchase of the Beneficial Interest Lessee
shall Exchange the obligations of Owner Trustee under the Notes and under the
Indenture in accordance with, subject to the conditions of and with the effect
provided in Section 5.05(a) hereof and Section 2.13 of the Indenture, and upon
such Exchange, Lessee shall have the right to terminate the Trust Agreement.

     (e) Owner Trustee and Lessee acknowledge and agree that the former Owner
Participant which shall have transferred the Beneficial Interest to Lessee
pursuant to this Section 11.03 (the "Transferor") is entitled to all Rent which
by its terms is payable in arrears accrued to and including, or attributable to
events or circumstances occurring prior to, the date of purchase pursuant to
this Section 11.03. Owner Trustee hereby agrees that upon receipt by it of any
amounts in respect of such Rent, it will forthwith pay over such amounts to the
Transferor.

     (f) From and after any purchase of the Beneficial Interest pursuant to this
Section 11.03, (i) the Transferor shall be released from its liability hereunder
and under the other Operative Documents to which it is or will be a party in
respect of obligations to be performed on or after the date of such purchase and
(ii) Lessee shall be deemed "Owner Participant" for all purposes of the
Operative Documents and each reference herein to Owner Participant shall
thereafter be deemed a reference to Lessee for all purposes.

     SECTION 11.04. Notice of Election to Exchange. In order to elect to
                    -------------------------------
exercise its right to effect an Exchange, Lessee shall irrevocably notify Owner
Trustee, Owner Participant and Indenture Trustee in writing thereof (i) at the
same time Lessee provides irrevocable notice to Lessor under Section 8(a), or
19(b) or 19(c) of the Lease, (ii) on the In-Service Date with respect to Section
2.08(a), or (iii) within seven days after the date that would have been the In-
Service Date with respect to Section 11.01.

                     Optional Refunding and Reoptimization
                     -------------------------------------

     SECTION 12.01. Refunding of Notes. Upon compliance with the terms and
                    -------------------
conditions of this Article XII, including without limitation the satisfaction of
the conditions set forth in Section 12.02 hereof, and of Section 2.12 of the
Indenture, Lessee shall have the right to request Owner Trustee to, and upon
such request Owner Participant, Owner Trustee and Indenture Trustee shall
cooperate in good faith to, take such steps as may be necessary to refund all or
any portion of the Series B Notes then outstanding (the "Refunded Notes") on not
more than one occasion (exclusive of (i) any Mandatory Refinancing described in
Section 10.01, or any other refinancing of the Series A Notes subsequent to the
Mandatory Refinancing Date, (ii) any refinancing of any financing arranged by
Agent pursuant to Section 10.01(c) or (d) and (iii) any refinancing of the
Series F Notes or the Series G Notes) through the issuance and sale in the
public or private market of other notes (the "Refunding Notes") in an aggregate
principal amount which shall be equal to the unpaid principal amount of the
Refunded Notes, plus up to 1% of such unpaid principal amount to cover expenses,
the proceeds of such issuance and sale to be applied to prepay the principal
amount of such outstanding Refunded Notes and, to the extent available, expenses
in connection with such refunding. Subject to the limitations set forth in
Section 12.02, the amortization or sinking fund schedules for the Refunding
Notes may be different from such schedules for the Refunded Notes. As a
condition to such refunding, Lessee will be liable for, and shall pay, on an
After-Tax Basis, the reasonable out-of-pocket expenses incurred by Owner
Trustee, Indenture Trustee and Owner Participant in connection with such
refunding (whether or not such refunding shall be consummated, so long as the
failure to consummate such refunding does not result solely from a default by
Owner Participant in its obligations hereunder).

     SECTION 12.02. Cooperation; Conditions. Owner Trustee, Indenture
                    ------------------------
Trustee and Owner Participant agree that each will cooperate with the others and
Lessee in any refunding contemplated by this Article XII and negotiate in good
faith to conclude such additional agreements and such supplements or amendments
to or consents or waivers under each of the Operative Documents as may be
reasonably requested by Lessee to effect the transactions contemplated in
connection with any such refunding, subject, however, to the following
conditions:

     (a) the refunding results in payment in full to the holder or holders of
the Refunded Notes of the unpaid principal amount of, Premium Amount, if any,
and accrued and unpaid interest on such Refunded Notes held by such holder or
holders, and of all other amounts then due and owing by Lessee to such holder or
holders pursuant to any other Operative Document;

     (b) no Bankruptcy Default or Event of Default shall have occurred and be
continuing as of the date of such refunding, and the refunding shall occur on a
Rent Payment Date;

     (c) the terms and conditions of such refinancing shall, pursuant to an
adjustment to the Factors as provided in and in accordance with Sections 12.05,
12.06, 12.07 and 12.08, in each case as applicable, preserve Owner Participant's
Net Economic Return as therein provided;

     (d) the Refunding Notes issued to refund the Refunded Notes shall have a
final maturity date not later than the final maturity date of the Refunded Notes
and a principal amount not in excess of the outstanding principal amount of the
Refunded Notes, plus up to 1% of such amount to cover expenses;

     (e) the average remaining life to maturity of the Refunding Notes issued to
refund the Refunded Notes as of the date of such refunding shall not be longer
or shorter than the average remaining life to maturity of the Refunded Notes as
of the date of such refunding by a period greater than six months;

     (f) [Intentionally Omitted]

     (g) Owner Participant, Owner Trustee and Indenture Trustee shall have
received (i) such opinions of
<PAGE>
 
                                                                              94

counsel as they may reasonably request concerning compliance with the Securities
Act and any other Applicable Law relating to the sale of securities and (ii)
such other opinions of counsel and such certificates and other documents, each
in form and substance reasonably satisfactory to each of them, as they may
reasonably request in connection with compliance with the terms and conditions
of this Article XII;

     (h) all necessary authorizations, approvals and consents shall have been
obtained;

     (i) Owner Participant shall have received from Independent Tax Counsel, an
opinion to the effect that Owner Participant is not incurring additional income
tax risk as a result of the terms and provisions, as opposed to the existence
of, such refinancing or, in lieu of such tax opinion, and provided that there
is, in the opinion of Independent Tax Counsel, a reasonable basis for taking the
reporting position requested by Lessee, an indemnity reasonably satisfactory to
Owner Participant from Lessee with respect to any such additional income tax
risk;

     (j) the terms and conditions of such Refunding Notes (excluding the
economic terms thereof) will, in the aggregate, be no less favorable to Owner
Participant than the terms and conditions applicable to the Refunded Notes, all
in the reasonable judgment of Owner Participant; provided, however, that if the
                                                 --------  -------
Refunded Notes shall have been issued in a public offering, in the event that
the Refunding Notes are to be privately placed, all the terms and conditions of
the Refunding Notes (excluding the economic terms thereof) will, in the
aggregate, be no less favorable to Owner Participant than the market terms and
conditions (excluding economic terms) upon which the Refunded Notes would have
been issued on the date actually issued, had the same been issued in a similar
type of private placement, all in the reasonable judgment of Owner Participant;
and

     (k) all reasonable out-of-pocket expenses incurred by Owner Participant in
connection with any such refinancing will be financed as part of the
refinancing, subject to paragraph (d) above, or paid on an After-Tax Basis by
Lessee.

     SECTION 12.03. Notice. Lessee shall give Owner Trustee, Owner Participant 
                    ------
and Indenture Trustee at least 45 days' prior written notice of any desired
refunding pursuant to this Article XII, which notice shall set forth to the
extent practicable the proposed terms and conditions of such refunding,
including the desired date therefor. Lessee, Owner Trustee, Owner Participant
and, as necessary, Indenture Trustee, shall consult thereafter on the
negotiation of such terms and conditions to the end that, subject to the
provisions of this Article XII, the final terms and conditions of such refunding
shall be agreed among the parties thereto in due course thereafter. Lessee will
provide notice promptly to such Persons in the event that Lessee determines not
to proceed with such proposed refunding.

     SECTION 12.04. Rights of Parties. Notwithstanding anything to the contrary 
                    -----------------
contained herein, in no event shall Owner Participant or Indenture Trustee have
any obligation to initiate or structure any refunding of Notes or to take, or to
cause Owner Trustee to take, any action in connection therewith other than such
as may be requested by Lessee as provided in this Article XII and in Article X.

     SECTION 12.05. Lease Rental Adjustments and Adjustment of Factors in
                    -----------------------------------------------------
Connection with Equity Syndication. The following provisions of this Section
- ----------------------------------                                        
12.05 relate to adjustments to the Factors, as set forth in Schedule III, to be
made after the Closing Date to and including the In-Service Date.

     (a) Mandatory Adjustments to Factors. In accordance with the following
         --------------------------------
provisions of this Section 12.05(a), the Factors shall be adjusted by Agent, on
behalf of Owner Participant, in the event that for any reason there is a change
in the assumptions designated as "Variable Pricing Assumptions" set forth in
Schedule III ("Variable Pricing Assumptions"). Such adjustment will be made in a
manner which shall preserve Owner Participant's Net Economic Return without
regard to the requirement to maintain the general pattern of accounting earnings
contained in the definition thereof (the "Limited OP Return") inherent in
Schedule III in effect as of the Closing Date and in such a way as to minimize,
in a manner reasonably satisfactory to HCG, the present value (discounted to the
In-Service Date using the Discount Rate) of (x) Scheduled Rent up to and
inclusive of the EBO Date and the EBO Amount (excluding any portion of Scheduled
Rent deemed to be "advance rent" on the EBO Date), as set forth
<PAGE>
 
                                                                              96

in Column E of Exhibit B to Schedule III (the "PV EBO"), and (y) Scheduled Rent
over the Basic Term as set forth in Column D of Exhibit A to Schedule III (such
minimization requirement being referred to as the "PV Minimization
Requirement"). Adjustments to the Factors pursuant to this Section 12.05(a)
shall be made as of each of the following dates:

     (i) the Debt Refinancing Date;

     (ii) the In-Service Date;

     (iii) if the In-Service Date has not yet occurred, then on the earliest to
occur of (A) the date on which it shall be determined that the Basic Term of the
Lease will be less than 9 years or greater than 10.5 years, (B) the date on
which it shall be determined that the actual weighted average interest rate
borne by the Series B Notes is greater than 10.0% per annum or (C) December 31,
1992 (the "Trigger Date"); and

     (iv) if either the Trigger Date or the Debt Refinancing Date has occurred,
the date on which a transfer to the Initial Transferee pursuant to Article XIII
is made (solely for purposes of providing a basis for the recalculation pursuant
to Section 12.05(d)).

     Any adjustment pursuant to this Section 12.05(a) shall be made in the same
manner, and shall employ the same (A) methodology, including among other things,
(i) the "multiple investment sinking fund" method of analysis without regard to
recourse borrowings used to fund any portion of the Commitment, the Deferred
Equity Amount or Transaction Costs, and with the objective of achieving a
targeted nominal after-tax book yield and not a return on assets or a return on
equity and (ii) an average annual total after-tax cash flow calculation and not
a total after-tax cash flow calculation (such methodology being hereinafter
referred to as the "OP Methodology"), (B) assumptions including, without
limitation, each of the Pricing Assumptions set forth in Schedule III or, if
there exists a Schedule III-A, the pricing assumptions set forth in Schedule 
III-A, except as such Variable Pricing Assumptions shall have been modified by
the event giving rise to such adjustment or by previous adjustments under this
Section 12.05(a) and (C) assumption relating to the Agent's Syndication Fee, in
each case as was made and as was employed in the calculation of the Factors set
forth in
<PAGE>
 
                                                                              97

Schedule III or, if there exists a Schedule III-A, as set forth in Schedule III-
A, in either case as in effect prior to the making of such adjustment. In making
any adjustment subsequent to the Debt Refinancing Date, the Debt Amortization
Schedule shall be allowed to vary only as would be permitted by the Indenture
and as directed by HCG assuming that the Notes then outstanding had been issued
based upon the Debt Amortization Schedule previously calculated pursuant to this
Section 12.05(a). The Factors resulting from and the Pricing Assumptions used in
any recalculation of Factors pursuant to this Section 12.05(a) shall amend the
existing Schedule III and be attached hereto as Schedule III unless such
adjustment occurs as of a date subsequent to the Trigger Date and, as of such
date, Agent, on behalf of Owner Participant, shall elect to further adjust the
Factors pursuant to Section 12.05(c) or (d), in which case such adjusted Factors
shall be disregarded.

     In connection with an adjustment to the Factors as of the Trigger Date,
Variable Pricing Assumptions that are estimates as of such date shall be updated
to the maximum extent possible; provided, however, that the Variable Pricing 
                                --------  -------
Assumptions relating to the assumed interest rate, In-Service Date and the lease
term shall be updated without exceeding the lease term duration parameter and
weighted average interest rate limit set forth in clause (iii) of Section
12.05(a) and assuming an In-Service Date no later than December 31, 1992.

     Unless otherwise expressly provided by Section 12.05(b), 12.05(c)(1) or
12.05(d), the Factors to be set forth on Schedule III and the related
Assumptions and Return (as defined below) of Owner Participant shall be
determined in accordance with this Section 12.05(a).

     (b) Recalculation of Factors Prior to Trigger Date. So long as the Trigger
         -----------------------------------------------
Date shall not have occurred, Agent, on behalf of Owner Participant, shall
further adjust the Factors previously calculated pursuant to Section 12.05(a),
within five Business Days thereof but in no event later than the Debt
Refinancing Date or the In-Service Date, as applicable, as of the Debt
Refinancing Date and the In-Service Date. In making such adjustment, Agent, on
behalf of Owner Participant, may change (I)(x) the Limited OP Return, (y) the
Pricing Assumptions designated as "Fixed Pricing Assumptions" on Schedule III
and (z) other pricing assumptions not reflected on Schedule III (such Limited
OP Return, Fixed Pricing Assumptions and other pricing assumptions being
referred to herein as the
<PAGE>
 
                                                                              98

"Assumptions and Return"), and (II) the Agent's Syndication Fee, provided that,
unless HCG shall have waived the requirements of any of clauses (i), (ii), (iii)
or (iv) below:

        (i)   the PV EBO resulting from such adjustment shall not be higher than
     the PV EBO calculated pursuant to Section 12.05(a) as of the date set forth
     in clause (i) or (ii) of Section 12.05(a), as applicable;

        (ii)  the Termination Values and Stipulated Loss Values resulting from
     such adjustment are not substantially higher than those calculated pursuant
     to Section 12.05(a), as of the date set forth in clause (i) or (ii) of
     Section 12.05(a), as applicable;

        (iii) the average life of the Debt Amortization Schedule resulting from
     such adjustment (x) if such adjustment is being made as of or prior to the
     Debt Refinancing Date, shall not vary by more than plus or minus two months
     from the average life of the full term debt amortization schedule
     calculated pursuant to Section 12.05(a) as of the date set forth in clause
     (i) or (ii) of Section 12.05(a), as applicable, and (y) if such adjustment
     is being made after the Debt Refinancing Date, shall vary only as permitted
     by the Indenture;

        (iv)  the final maturity of the Debt Amortization Schedule resulting
     from such adjustment (x) if such adjustment is being made as of or prior to
     the Debt Refinancing Date, shall not be more than six months later than the
     final maturity of the full term debt amortization schedule calculated
     pursuant to Section 12.05(a) as of the date set forth in clause (i) or (ii)
     of Section 12.05(a), as applicable, and in no event later than the last day
     of the Basic Term and (y) if such adjustment is being made after the Debt
     Refinancing Date, shall vary only as permitted by the Indenture; and

        (v)   the changed Assumptions and Return and changed Agent's Syndication
     Fee shall be those of the Initial Transferee or, if there is no Initial
     Transferee, those of the prospective Initial Transferee (as defined below).

All adjustments to the Factors pursuant to this Section 12.05(b) shall be made 
utilizing the same Variable
<PAGE>
 
                                                                              99

Pricing Assumptions and the same OP Methodology utilized in making the
corresponding adjustment pursuant to Section 12.05(a), shall satisfy the PV
Minimization Requirement and, in calculating the Termination Values and
Stipulated Loss Values pursuant to this Section 12.05(b), such values shall
reflect the actual Agent's Syndication Fee and the actual Assumptions and
Return.

     The Assumptions and Return resulting from the calculations made pursuant to
this Section 12.05(b) shall be used for purposes of making any adjustments to
the Factors subsequent to the earliest date that Agent, on behalf of Owner
Participant, shall adjust the Factors pursuant to this Section 12.05(b), except
that Agent, on behalf of Owner Participant, may change the Assumptions and
Return (i) in connection with a transfer to an Initial Transferee pursuant to
Section 12.05(d) or (ii) in the event that there is no Initial Transferee at the
time, to those of the Prospective Initial Transferee, provided that such changed
Assumptions and Return would satisfy the requirements of Section 12.05(d) as if
a transfer to the Prospective Initial Transferee were being made pursuant to
Section 12.05(d). The Factors resulting from and. the Pricing Assumptions used
in any recalculation of the Factors pursuant to this Section 12.05(b) shall
amend the existing Schedule III and be attached hereto as Schedule III.
Concurrently therewith, the Schedule III previously in effect shall be attached
as Schedule III-A.

     In addition to the foregoing provisions of this Section 12.05(b), on the 
In-Service Date, Agent, on behalf of a subsequent Prospective Initial
Transferee, may change the Assumptions and Return previously calculated with
respect to the Prospective Initial Transferee referred to in clause (ii) of the
preceding paragraph on the Debt Refinancing Date, if any, to those of such
subsequent Prospective Initial Transferee if, and only if, such Prospective
Initial Transferee fails to become the Initial Transferee, provided that such
changed Assumptions and Return would satisfy the requirements of Section
12.05(d) as if a transfer to the subsequent Prospective Initial Transferee were
being made pursuant to Section 12.05(d). The change described in the immediately
preceding sentence may be made by Agent subsequent to the satisfaction of any of
the waiver requirements on the part of HCG on the In-Service Date under the
Reoptimization Agreement.

     As used herein, "Prospective Initial Transferee" shall mean an entity that
(i) would qualify as an Initial
<PAGE>
 
                                                                             100

Transferee under Article XIII, (ii) has reached an understanding with Agent on
behalf of Owner Participant as to the principal terms on which such entity would
be willing to become the Initial Transferee, (iii) has expressed to Owner
Participant in writing its interest in becoming the Initial Transferee and (iv)
Owner Participant reasonably believes is highly likely to become the Initial
Transferee, all as certified to HCG by a Responsible Officer of Owner
Participant.

     (c) Recalculation of Factors as of or After Trigger Date. (1) As of the 
         -----------------------------------------------------
Trigger Date, Agent, on behalf of Owner Participant, may further adjust the
Factors previously calculated pursuant to Section 12.05(a), within five Business
Days after the Trigger Date but in no event later than the In-Service Date. In
making such adjustment, Agent, on behalf of Owner Participant, shall use the
Assumptions and Return resulting from the calculations, if any, made pursuant to
Section 12.05(b), or (x) if the Prospective Initial Transferee referred to in
clause (ii) of the antepenultimate paragraph of Section 12.05(b) shall have
failed to become the Initial Transferee, may change the Assumptions and Return
to those of the subsequent Prospective Initial Transferee, provided that such
changed Assumptions and Return pursuant to this clause (x) would satisfy the
requirements of Section 12.05(d) as if a transfer to the subsequent Prospective
Initial Transferee were being made pursuant to Section 12.05(d), or (y) if no
such calculations have been made pursuant to Section 12.05(b), may change the
Assumptions and Return and the Agent's Syndication Fee to those of the
Prospective Initial Transferee, or (z) may change the Assumptions and Return
resulting from the calculations, if any, made pursuant to Section 12.05(b) to
those of the Prospective Initial Transferee, if there was no Prospective Initial
Transferee on the date such calculations were made pursuant to Section 12.05(b),
provided that such changed Assumptions and Return pursuant to this clause (z)
would satisfy the requirements of Section 12.05(d) as if a transfer to the
Prospective Initial Transferee were being made pursuant to Section 12.05(d);
provided, however, that in each case, unless HCG shall have waived the 
- --------  -------
requirements of any of clauses (i), (ii), (iii) or (iv) below:

     (i) the PV EBO resulting from such adjustment shall not be higher than the
         PV EBO calculated as of the Trigger Date pursuant to clause (iii) of
         Section 12.05(a);
<PAGE>
 
                                                                             101

          (ii) the Termination Values and Stipulated Loss Values resulting from
     such adjustment are not substantially higher than those calculated as of
     the Trigger Date pursuant to clause (iii) of Section 12.05(a);

          (iii) the average life of the Debt Amortization Schedule resulting
     from such adjustment (x) if such adjustment is being made prior to or as of
     the Debt Refinancing Date shall not vary by more than plus or minus two
     months from the average life of the full term debt amortization schedule
     calculated as of the Trigger Date pursuant to clause (iii) of Section
     12.05(a) and (y) if such adjustment is being made after the Debt
     Refinancing Date, shall vary only as permitted by the Indenture;

          (iv) the final maturity of the Debt Amortization Schedule resulting
     from such adjustment (x) if such adjustment is being made prior to or as of
     the Debt Refinancing Date shall not be more than six months later than the
     final maturity of the full term debt amortization schedule calculated as of
     the Trigger Date pursuant to clause (iii) of Section 12.05(a) and in no
     event later than the last day of the Basic Term and (y) if such adjustment
     is being made after the Debt Refinancing Date, shall vary only as permitted
     by the Indenture; and

          (v) the changed Assumptions and Return and changed Agent's Syndication
     Fee shall be those of the Initial Transferee or, if there is no Initial
     Transferee, those of the Prospective Initial Transferee or the subsequent
     Prospective Initial Transferee, as applicable.

If Agent, on behalf of Owner Participant, adjusts the Factors, the Assumptions
and Return and Agent's Syndication Fee pursuant to Section 12.05(c)(1), then the
Assumptions and Return and Agent's Syndication Fee resulting from the
calculations made pursuant to Section 12.05(b) or Section 12.05(c)(1), as
applicable, shall be used for purposes of making any adjustments to the Factors
as of a date from and after the Trigger Date unless such Assumptions and Return
and Agent's Syndication Fee are subsequently changed-pursuant to Section
12.05(c)(2) or 12.05(d). The Factors resulting from and the Pricing Assumptions
used in any recalculation of the Factors pursuant to this Section 12.05(c)(1)
shall become the amended Schedule III and shall be attached hereto as Schedule
III. Concurrently

                                                                             102

therewith, the Schedule III previously in effect shall be attached as Schedule
III-A and shall replace the previously effective Schedule III-A, if any.

All adjustments to the Factors pursuant to this Section 12.05(c)(1) shall be
made utilizing the same Variable Pricing Assumptions and the same OP Methodology
utilized in making the corresponding adjustment pursuant to Section 12.05(a),
shall satisfy the PV Minimization Requirement and, in calculating the
Termination Values and Stipulated Loss Values pursuant to this Section
12.05(c)(1), such values shall reflect the actual Agent's Syndication Fee and
the actual Assumptions and Return.

           (2) In the event that an adjustment to the Factors shall have been
required pursuant to Section 12.05(a) and such adjustment is as of a date
subsequent to the Trigger Date which previously gave rise to an adjustment
pursuant to Section 12.05(a), Agent, on behalf of Owner Participant, shall
further adjust the Factors set forth in Schedule III. In making such adjustment,
Agent, on behalf of Owner Participant, shall use the same (a) Assumptions and
Return, (b) Agent's Syndication Fee, (c) Variable Pricing Assumptions, except as
such Variable Pricing Assumptions shall have been modified by the event giving
rise to such adjustment or by previous adjustments under Section 12.05(a), and
(d) OP Methodology as were used in the recalculation of the Factors set forth in
Schedule III, and shall satisfy the PV Minimization Requirement; provided,
                                                                 --------
however, that if the Debt Refinancing Date occurs subsequent to the Trigger
- -------
Date, and if there was no Prospective Initial Transferee as of the Trigger Date,
in making the further adjustment to the Factors pursuant to this Section
12.05(c)(2), the Assumptions and Return and Agent's Syndication Fee may be
changed to those of the Prospective Initial Transferee, provided that such
Assumptions and Return and Agent's Syndication Fee would satisfy the
requirements of Section 12.05(c)(1) as if a transfer to the Prospective Initial
Transferee were made pursuant to Section 12.05(d) as of the Trigger Date. The
Factors resulting from and the Pricing Assumptions used in any recalculation
pursuant to this Section 12.05(c)(2) shall amend the existing Schedule III and
be attached hereto as Schedule III. In calculating the Termination Values and
Stipulated Loss Values pursuant to this Section 12.05(c)(2), such values shall
reflect the actual Agent's Syndication Fee and the actual Assumptions and
Return.

          (d) Recalculation of Factors Pursuant to Transfer After Debt

Refinancing Date or Trigger Date. If either the Debt Refinancing Date or the
- ---------------------------------                                          
Trigger Date shall have previously occurred, Agent, in connection with a
transfer to the Initial Transferee pursuant to Article XIII, on behalf of
Initial Transferee, may adjust the Factors previously calculated pursuant to
Section 12.05(a) as of the date of such transfer. In making such adjustment,
Agent, on behalf of Initial Transferee, may change the Assumptions and Return
and Agent's Syndication Fee, utilizing the Variable Pricing Assumptions set
forth in Schedule III on the date of such transfer, provided that:

          (i) the PV EBO resulting from such adjustment would not be higher than
     the PV EBO set forth in Schedule III on the date of such transfer;

          (ii) Termination Values and Stipulated Loss Values resulting from such
     adjustment would not be substantially higher than those set forth in
     Schedule III on the date of such transfer;

          (iii) the average life of the Debt Amortization Schedule resulting
     from such adjustment (x) if such transfer is being made prior to or as of
     the Debt Refinancing Date shall not vary from the average life of the full
     term debt amortization schedule set forth in Schedule III on the date of
     such transfer and (y) if such transfer is being made after the Debt
     Refinancing Date, shall vary only as permitted by the Indenture; and

          (iv) the final maturity of the Debt Amortization Schedule resulting
     from such adjustment (x) if such transfer is being made prior to or as of
     the Debt Refinancing Date shall not be later than the final maturity of the
     full term debt amortization schedule set forth in Schedule III on the date
     of such transfer and in no event later than the last day of the Basic Term
     and (y) if such transfer is being made after the Debt Refinancing Date,
     shall vary only as permitted by the Indenture.

If Agent, on behalf of Owner Participant, adjusts the Factors, the Assumptions
and Return and Agent's Syndication Fee pursuant to Section 12.05(d), then the
Assumptions and Return and Agent's Syndication Fee resulting from the
calculations made pursuant to Section 12.05(d) shall be used for purposes of
making any further adjustments to the
<PAGE>
 
                                                                             104

Factors. The Factors resulting from and the Pricing Assumptions used in any
recalculation pursuant to this Section 12.05(d) shall amend the existing
Schedule III and be attached hereto as Schedule III. All adjustments to the
Factors pursuant to this Section 12.05(d) shall be made utilizing the same
Variable Pricing Assumptions and the same OP Methodology utilized in making the
corresponding adjustments pursuant to Section 12.05(a), shall satisfy the PV
Minimization Requirement and, in calculating the Termination Values and
Stipulated Loss Values pursuant to this Section 12.05(d), such values shall
reflect the actual Agent's Syndication Fee and the actual Assumptions and
Return.

          (e) During the period from the Closing Date to, but not including, the
In-Service Date, Agent or HCG may provide written notice to the other of any
Proposed Tax Law Change, and Agent or HCG shall amend Schedule V to reflect such
Proposed Tax Law Change. During the period from the Closing Date to the In-
Service Date, Agent or HCG may give written notice to the other of any Covered
Tax Law Change, and Agent and HCG shall amend Schedule V to reflect such Covered
Tax Law Change.

          (f) Notwithstanding anything to the contrary contained herein, the
Assumptions and Return and the Agent's Syndication Fee shall not be changed in
connection with any recalculation of the Factors which occurs after the In-
Service Date.

          (g) In connection with any transfer of the stock of Owner Participant
by Parent or of the assets of Owner Participant during the period from the
Closing Date to and including the In-Service Date, in each case in accordance
with Article XIII, upon the provision to HCG of the notice required by Section
13.02(a)(ix), HCG may request that Agent, on behalf of Owner Participant,
recalculate, from time to time, the Factors using the Assumptions and Return of
Owner Participant, the actual Agent's Syndication Fee and any variable pricing
assumptions specified by HCG and will provide a statement to HCG containing such
recalculated Factors stating that such Factors are the relevant Factors under
Section 12.05 based upon such variable pricing assumptions and such other
information as HCG shall reasonably request for purposes of providing such
information to its public accountants in connection with evaluating the
applicable Lease under FAS-13.

          (h) Notwithstanding anything to the contrary contained herein, the
provisions of Sections 12.05(b), 12.05(c) and 12.05(d), taken together, shall
not operate or permit a change to the Assumptions and Return from the
Assumptions and Return resulting from the calculations pursuant to Section
12.05(a) more than one time in the aggregate, except that the Assumptions and
Return may be changed one additional time (i) with respect to a change in the
Assumptions and Return made by Agent on behalf of an Initial Transferee pursuant
to Section 12.05(d) subsequent to a change in the Assumptions and Return
previously made by Agent on behalf of the transferring Owner Participant
pursuant to Section 12.05(b) or 12.05(c)(1) or (ii) in respect of each of the
Prospective Initial Transferee or the subsequent Prospective Initial Transferee
as described in Section 12.05(b) or 12.05(c)(1); provided, however, that Agent's
                                                 --------- --------            
Syndication Fee shall be permitted to change each time that a recalculation of
the Factors is made under Section 12.05(b), 12.05(c)(1), 12.05(c)(2) in the
circumstance described in the proviso contained therein or 12.05(d). In
addition, on and after the In-Service Date, in the event of a change in Owner
Participant's Assumptions and Return pursuant to Section 12.05(b), 12.05(c) or
12.05(d), the definition of Owner Participant's Net Economic Return shall be
amended to reflect such change.

          (i) After the Debt Refinancing Date, for purposes of Sections
12.05(b), 12.05(c) and 12.05(d), the Indenture shall not be deemed to permit the
average life of any Debt Amortization Schedule to vary unless HCG shall so elect
by written notice delivered to Owner Trustee and Owner Participant.

          SECTION 12.06. Lease Rental Adjustments and Adjustment of Factors
                         --------------------------------------------------
Subsequent to In-Service Date. The following provisions of this Section 12.06
- ------------------------------
relate to ad justments to the Factors, as set forth in Schedule III, to be made
after the In-Service Date.

          Adjustments to Factors. In accordance with the following provisions of
          -----------------------                                              
this Section 12.06, the Factors shall be adjusted by Owner Participant to take
into account (i) the actual amount and timing of payment of Transaction Costs,
if other than as set forth in Schedule III, as amended, (ii) any refinancing of
the Notes provided for by this Agreement, (iii) the actual Deferred Equity
Amount or the timing of payment thereof, if other than as set forth in Schedule
III, as amended, (iv) any Covered Tax Law Change of the type described in clause
(i) of the definition thereof,
<PAGE>
 
                                                                             106

(v) any reset of the interest rate on the Series A Notes or the Series G Notes
and (vi) repayment of the Series F Notes or the Series G Notes by a Supplemental
Rent payment pursuant to Section 10.01(a)(iv) of this Participation Agreement.
Such adjustment will be made in a manner which shall preserve Owner
Participant's Net Economic Return (in this case with regard to the general
pattern of accounting earnings as set forth in the definition thereof) and in
such a way as to satisfy the PV Minimization Requirement.

Any adjustment pursuant to Section 12.06 shall be made in the same manner, and
shall employ the same (A) OP Methodology, (B) assumptions including, without
limitation, each of the Pricing Assumptions set forth in Schedule III, except as
such Variable Pricing Assumptions shall have been modified by the event giving
rise to such adjustment or by previous adjustments under this Section 12.06, (C)
Assumptions and Return and (D) Agent's Syndication Fee, in each case as was made
and as was employed in the calculation of the Factors set forth in Schedule III
as in effect prior to the making of such adjustment. In making any adjustment
subsequent to the Debt Refinancing Date, the Debt Amortization Schedule shall be
allowed to vary only as would be permitted by the Indenture and as directed by
HCG.

          SECTION 12.07. Confirmation of Adjustments; Further Assurances. (a)
                         ------------------------------------------------   
The adjustment to any of the Factors pursuant to Section 12.05 or 12.06 shall be
determined by Agent, on behalf of Owner Participant, with respect to adjustments
occurring on or prior to the In-Service Date and thereafter by Owner
Participant. The Agent or Owner Participant, as applicable, shall provide to
Lessee, Lessor, Indenture Trustee and, if appropriate, Owner Participant, notice
of such adjustment accompanied by an Officer's Certificate of Agent or Owner
Participant, as applicable, which Officer's Certificate shall set forth such
adjustment and which shall confirm that such adjustment was made in accordance
with the provisions of Section 12.05 or 12.06, as applicable and Section 12.08.
Such adjustment shall, subject to the following provisions of this Section
12.07, become effective not later than the Debt Refinancing Date or the In-
Service Date, as applicable, or if such adjustment occurs after the In-Service
Date, on the next succeeding Rent Payment Date, which occurs at least
15 days after the date of such adjustment, or, if later, the date of the
conclusion of the verification procedure set forth in Section 12.07(b) (in each
case taking into effect the effective date of such adjustment).

                                                                             107

          (b) Within five Business Days after receipt of an Officer's
Certificate pursuant to paragraph (a) above in respect of an adjustment pursuant
to Section 12.05 or within 20 Business Days after receipt of an Officer's
Certificate pursuant to paragraph (a) above in respect of an adjustment pursuant
to Section 12.06, if Lessee believes that such adjustment is incorrect, Lessee
may request that such adjustment be verified by one of the six largest U.S.
independent public accounting firms, including Agent's or Owner Participant's
regular independent accounting firm, as selected by Agent or Owner Participant,
as applicable, provided that, with respect to related verifications under this
Agreement and any Other Participation Agreement in which Owner Participant or an
Affiliate is the owner participant thereunder, Agent or Owner Participant, as
applicable, shall select the same public accounting firm hereunder and
thereunder, it being understood that Agent shall select the same public
accounting firm under this and each Other Participation Agreement. In such
verification process, such accounting firm shall be given access by Agent and
Owner Participant to the assumptions, methods of calculation, computations,
computer programs and files employed by Agent and Owner Participant in
calculating such proposed adjustment and employed in the original calculation of
the Factors, subject to the execution of such confidentiality agreements as
Agent and Owner Participant shall reasonably request.

          Such verification by such accounting firm shall be at the expense of
Lessee unless such verified adjustment results in a readjustment in favor of
Lessee that exceeds five basis points in the PV EBO, in which case verification
shall be at the expense of Owner Participant. Such determination of the
adjustment by Agent or Owner Participant, as applicable, or, if so requested in
accordance with this Section 12.07(b), such verified adjustment, as the case may
be, shall be conclusive and binding on the parties hereto. Owner Participant
will not be liable for verification expenses if the cause of the readjustment
that would otherwise give rise to the liability is the employment of an
optimizing technique which is not known by Agent or Owner Participant, as
applicable, as of the date of such readjustment.

          (c) At the time any adjustment is made pursuant to Section 12.05 or
12.06 or this Section 12.07, the parties hereto shall memorialize such
adjustment as appropriate and shall enter into such amendments to the Operative
Documents (including an amendment to Schedule III, and Schedule III-A,
<PAGE>
 
                                                                             108

if applicable, as then amended, to this Agreement and a supplement to the Lease)
and do such further acts as may be reasonably required in order to effectuate
such adjustment; provided that such adjustment shall become effective as
                 --------                                              
provided in this Section 12.07 without regard to the date on which any such
document is executed and delivered; and further provided that any amendment to
                                        ------- --------                     
Schedule III, and Schedule III-A, if applicable, pursuant to Section 12.05,
12.06 or 12.07 may be made by Agent, Owner Participant and HCG.

          SECTION 12.08. Compliance with Code. (a) All Rental Adjustments under
                         ---------------------                                
Section 12.05 or 12.06 will comply with Section 4.07(1), 4.07(2) and 4.08 of
Rev. Proc. 75-28 and Section 467 of the Code (provided Section 4.08 of Rev.
Proc. 75-28 and Section 467 of the Code will be applied on a prospective basis
from the date of such adjustment, except that in the case of a refinancing of
the Series B Notes, Series F Notes, and Series G Notes after the In-Service
Date, the original 90-110 pattern, as previously adjusted, will be preserved but
without taking into account actual Scheduled Rent payments made prior to the
adjustment).

          (b) In connection with any recalculation of the Factors pursuant to
Section 12.05, to the extent necessary to satisfy the PV Minimization
Requirement and if Lessee so requests, the EBO Date may be changed, provided
that the Limited OP Return is maintained in accordance with Section 12.05. Agent
shall have the right to consent to any change in the EBO Date that differs by
more than one year.

     Title I of ERISA or Section 4975 of the Code or (ii) such transfer to or
     ownership by such Initial Transferee will not result in a "prohibited

     Person arising from a breach by Lessee or Contractor of any Significant
     Provisions;

          (e) nothing contained in this Section 14.02 shall limit the exercise
     by an Owner Person of any rights such Owner Person may have under any other
     Operative Document or Hughes Agreement (including, without limitation, the

     payments pursuant to this Agreement to the extent such Owner Person has
     already received payment for the damages resulting from such breach
     pursuant to the provisions of any Operative Document or Hughes Agreement;

Date) with an appropriate legend, marking, stamp or other obvious written
identification prior to disclosure. In the event that Lessee discloses its
Proprietary Information to Recipient other than in the manner provided for in
this paragraph (b), then HCG or Lessee, as applicable, shall promptly inform
Recipient that such information is deemed proprietary and shall provide
Recipient with a brief written description of such information within thirty
(30) days of such disclosure, identifying therein the manner, place, and date of
such disclosure and the names of Recipient's representatives to whom such
disclosure was made whereupon the provisions of this agreement shall become
applicable to such Proprietary Information. Proprietary Information shall also
mean any information, whether in written form or not, prepared by Recipient or
anyone receiving Proprietary Information from Recipient or incorporating
Proprietary Information.

          (c)  Recipient shall not use the Proprietary Information, except in
connection with the transactions contemplated by the Operative Documents or the

compliance therewith within thirty (30) days of such written request.

          (e)  The disclosure of Proprietary Information under this Section
15.01 shall not be construed as granting either a license under any patent,
patent application, or copyright, or any right of ownership in said Proprietary
Information, nor shall such disclosure constitute any representation, warranty,
assurance, guarantee, or inducement by Lessee with respect to infringement of
patents or other rights of others.

parties with respect to the safeguarding of Proprietary Information, supersedes

     Date on which a payment of interest is due on the Notes, if and to the
     extent that on or prior to any such date, Lessor shall not have remitted
     funds to Indenture Trustee (in accordance with clause (k) below or
     otherwise) in an amount equal to the amount of interest due and payable on
     the Notes on such date (such amount being referred to as the "Lessor
     Interim Amount"), Lessee shall loan to Lessor an amount equal to any
     portion of the Lessor Interim Amount not paid by Lessor. Lessor shall give
     notice to Lessee and Indenture Trustee at least five Business Days prior to
     such interest payment date if funds equal to the Lessor Interim Amount will
     not be paid by Lessor on such date, provided, however, that Lessor's
                                         --------  -------
     failure to deliver such notice shall not affect Lessee's obligation under
     this Section 3(b)(i)(A). (B) In addition, subject to adjustment as provided

     subject to Sections 12.07 and 12.08, of the Participation Agreement, as
     applicable, Lessee shall pay to Lessor installments of Base Rent during the
     Basic Term on each Rent Payment Date during the Basic Term, each such

     forth in Schedule A opposite the applicable Rent Payment Date, multiplied
     by Lessor's Cost for such Transponder, and (B) the Rent Differential Amount
     for such Transponder, if any. In addition, in the event that any interest
     on the Notes becomes due and payable during the Basic

                                       2
<PAGE>
 
     Term on a date other than on a Rent Payment Date, Lessee shall pay to
     Lessor, on such date, Base Rent in an amount equal to the amount of such
     interest.

          Base Rent with respect to any Transponder during any Renewal Term
shall be payable as provided in Section 18.

          (c) Supplemental Rent.
              ----------------- 

              (i)   Lessee shall pay to Lessor, for its own account, or to any

     Payment Date, Lessor shall not have remitted to Indenture Trustee (in
     accordance with clause (k) below or otherwise) funds in an amount (the
     "Lessor Payment Amount") equal to the amount, if any, set forth in Schedule
     III to the Participation Agreement and designated as the "Lessor Payment
     Amount," which amount shall represent scheduled payments of principal on
     the Notes due on or prior to the Interim Rent Payment Date (as such amount
     may be adjusted pursuant to Section 12.05 or 12.06, subject to Sections
     12.07 and 12.08, of the Participation Agreement, as applicable), Lessee
     shall loan to Lessor on the Interim Rent Payment Date an amount equal to
     the difference between any portion of the Lessor Payment Amount not
     remitted to Indenture Trustee by Lessor and any amount paid by Lessee
     referred to in clause (B) of Section 3(b)(i) that has not previously been
     or is not simultaneously being applied against any portion of the Lessor
     Interim Amount not paid by Lessor. Lessor shall give notice to Lessee and
     Indenture Trustee at least five Business Days prior to each date on which a
     Lessor Payment Amount is due if funds equal to the Lessor Payment Amount

     to Seller an amount equal to any amounts due from buyer to seller under the
     Purchase Agreement, other than Buyer's Cost, in each case with respect to
     any Transponder for the period that such Transponder is subject to this
     Lease.

              -----------------
Excepted Payments) payable to Lessor shall be paid to Indenture Trustee (to its

including any Excepted Payment payable to any Person pursuant to any Operative
Document or any Hughes Agreement shall be paid to such Person as provided in

Day, in which case such payment shall be due and payable on the immediately
succeeding Business Day with the same force and effect as if made on such
scheduled date, and (provided such payment is made on such next succeeding
Business Day) no interest shall accrue on the amount of such payment from and
after such scheduled date.

          (e) Late Payment. If any Rent shall not be paid when due, Lessee shall
              ------------
pay to Lessor or to Indenture Trustee, as the case may be (or, in the case of
Supplemental Rent, to any Person entitled thereto as provided herein or in any
other Operative Document or Hughes Agreement), as Supplemental Rent, interest
(to the extent permitted by law) on such overdue amount from and including the
due date thereof to but excluding the date of payment thereof (unless payment is

Section 3(j) hereof), in which event such date of payment shall be included) at
the Overdue Rate.

          (f) Minimum Payment. Notwithstanding any other provision of the Lease
              ---------------

Hughes Agreement, (1) for any Transponder, the amount of Interim Rent, Base Rent
and Deferred Equity Amount payable on any day on which Interim Rent or Base Rent

equal to the amount of scheduled principal and accrued interest due and payable
on the Notes outstanding on such day in respect of such Transponder and (2) for
any Transponder, the amount of Stipulated Loss Value, Termination Value and the
EBO Amount, as each such amount may be adjusted pursuant to Section 12.05 or
12.06, subject to Sections 12.07 and 12.08, of the Participation Agreement, as
applicable, together with the arrears portion of both the Scheduled Rent and
Rent Differential Amount payable under this Lease on any such date in respect of
such Transponder (excluding, in each case, any portion thereof constituting an
Excepted Payment), shall be at least equal to the amount of principal and
accrued interest which would be due and payable on the Notes outstanding on such
date in respect of such Transponder, assuming such date or the EBO Date, as the
case may be, was the date such payment was due on the Notes in respect of such
Transponder in connection with any payment by Lessee of such Stipulated Loss
Value, Termination Value or EBO Amount.

          (g) Net Lease; No Setoff, etc. This Lease is a net lease and,
              --------------------------
notwithstanding any other provision of this Lease to the contrary (except as

therein; (4) any restriction, prevention, interruption or curtailment of or

part thereof or interest therein; (5) any defect in, or any Lien on, title to
the Transponders, or any part thereof or interest therein or any other
restriction thereon; (6) any change, waiver, extension, indulgence or other

Guarantor, Lessee or Lessor; (7) any bankruptcy, insolvency, reorganization,
discharge or forgiveness of indebtedness, composition, adjustment, dissolution,
liquidation or other like proceeding relating to Seller, Guarantor, Lessee,
Indenture Trustee, Lessor, Owner Participant, any Noteholder or any other
Person, or any action taken with respect to this Lease by any

                                       4

trustee or receiver of any Person mentioned above, or by any court; (8) any
claim that Lessee or Guarantor has or might have against any Person, including,
without limitation, Indenture Trustee, any Noteholder, Lessor or Owner
Participant (but this Section 3(g) shall not constitute a waiver of any such
claims); (9) any failure on the part of Lessor, Indenture Trustee, Owner
Participant or any Noteholder to perform or comply with any of the terms hereof
or of any other Operative Document or Hughes Agreement; (10) any invalidity or
unenforceability or impossibility of performance, or disaffirmance, of any
provision of this Lease or any of the other Operative Documents or Hughes

any Applicable Laws now or hereafter in force; (12) any failure to obtain or to

or knowledge of any of the foregoing. Except as expressly provided herein,
Lessee, to the extent permitted by law, waives all rights now or hereafter
conferred by statute or otherwise to quit, terminate or surrender this Lease, or
to any diminution or reduction of Rent payable by Lessee hereunder. If this
Lease shall be terminated in whole or in part for any reason whatsoever except
as expressly provided in this Lease, Lessee shall nonetheless pay to Lessor (or,
in the case of Supplemental Rent, to Lessor for its own account or to any Person
entitled to such Supplemental Rent as specified herein or in the appropriate
Operative Document or the Hughes Agreement), an amount equal to each Rent
payment at the time and in the manner that such payment would have become due

or in part. Except with respect to payment of any Advance Amount and as
otherwise provided in Section 3(h) hereof and Section 2.07(b) of the
Participation Agreement, each payment of Rent shall be final, and Lessee agrees
not to seek to recover all or any part of any such payment from Lessor,
Indenture Trustee or Owner Participant for any reason under any circumstance

prevent Lessee from bringing an action for damages suffered by Lessee as a
result of the breach by any Person of any obligation of such Person expressly
stated in any Operative Document or Hughes Agreement or for equitable relief to
obtain compliance with any such obligation, or for the return of mistakenly paid
amounts of any Rent or from exercising the rights set forth in Section 3(h)
hereof and Section 2.07(b) of the Participation Agreement. Nothing contained in
this Section 3(g) shall be construed as: (1) a guaranty of (i) the value of the
Transponders upon termination of the Basic Term or any Renewal Term or (ii) the
useful life of the Transponders or (iii) payment of any of the Notes; or (2) a
prohibition of assertion of any claim against any manufacturer, supplier,
dealer, vendor, contractor, subcontractor or installer with respect to the
Transponders; or (3) a waiver by Lessee of its right to assert and sue upon any
claims it may have against any other Person in one or more separate actions.

          (h) Repayment of Advance Amount. Lessee may be repaid, in the manner
              ---------------------------
provided in the next sentence, any amounts constituting Advance Amount (which
shall mean (i) any amounts due on Defaulting Participant's Note, (ii) any
liquidated damages pursuant to Section 2.07(b)(i) of the Participation Agreement
and (iii) any portion of the Deferred Equity Amount advanced by Lessee pursuant
to Section 3(b)(i)(A) or 3(c)(ii) hereof (excluding any portion thereof required
to be paid by Lessee pursuant to Section 2.12(b) of the Participation
Agreement), plus, in the case of (I) the outstanding portion of such liquidated
damages and (II) any such advanced Deferred Equity Amount, interest thereon

                                       5
<PAGE>
 
at a simple interest rate of 14% per annum from the date such liquidated damages
accrue or from the date that any portion of such Deferred Equity Amount is
advanced by Lessee, as applicable, to but not including the date such damages
and/or amounts are repaid by Lessor), any repayment of the Advance Amount to be
deemed applied first in satisfaction of amounts owing under clause (i) and
thereafter as Lessee shall determine, in Lessee's discretion. In order to effect
a repayment of the Advance Amount, Lessee shall be entitled to offsets (without
duplication) against any payments of Rent (other than as limited by the three
provisos to this sentence) due from Lessee to Lessor (including, without
limitation, Interim Rent, Base Rent, Supplemental Rent, Stipulated Loss Value,
Termination Value or the EBO Amount and all other amounts payable to Lessor in
connection with any termination of this Lease, but excluding Excepted Payments
payable to the Trust Company) until Lessee has received the full amount of the
Advance Amount, whether by cash payment, offsets as herein provided, or any
combination thereof; provided, however, that, in case of any payment due to
                     --------  -------

              (i) Lessee, in its capacity as Seller under the Purchase
     Agreement, is making certain representations and warranties and undertaking
     certain payment obligations to Lessor in its capacity as Buyer under the
     Purchase Agreement with respect to the Transponders. None of the provisions

     NOR SHALL BE DEEMED TO HAVE MADE ANY REPRESENTATION OR WARRANTY, EXPRESS OR
     IMPLIED, WITH RESPECT TO ANY TRANSPONDER, OR ANY PART THEREOF, IN THIS

     INCLUDING, WITHOUT LIMITATION, AS TO THE TITLE, VALUE, COMPLIANCE WITH
     SPECIFICATIONS, CONDITION, DESIGN, QUALITY, DURABILITY, OPERATION,
     MERCHANTABILITY OR FITNESS FOR USE OR PURPOSE OF SUCH TRANSPONDER, AS TO
     THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO

     the Service Agreement.

          (ii) Lessor hereby agrees that so long as no Event of Default shall
     have occurred and be continuing with respect to a Transponder, Lessor shall
     not exercise, during the Lease Term for such Transponder, any of its rights

     of its rights to any indemnity or other payments (other than rights to
     payment representing downward adjustment to the purchase price of the
     Transponders pursuant to Section 2.03 of the Purchase Agreement) with
     respect to such Transponder; provided that Lessee cannot waive the
                                  --------
     obligations of Seller or Contractor, and Lessor may exercise any rights and
     remedies it might have, under Sections 5.01, 5.03, 5.05, 8.01, 10.02,
     15.10, 15.12 and the last sentence of 15.16 of the Purchase Agreement and

     enforce its rights under the Lease or the Purchase Agreement to cause
     Lessee or Seller to defend such title in accordance with the provisions
     hereof or thereof. Lessee may consent to the preemption or interruption
     of any Transponder by Seller under Section 7.01 of the Purchase Agreement,
     without regard to the Transponder Priority List set forth in Appendix E
     thereto, and such preemption or interruption shall not constitute a
     Confirmed Failure (if it would otherwise constitute a Confirmed Failure)
     only if: (a) such preemption or interruption will not adversely affect the
     ability (1) of Lessee to meet its obligations under this Lease or any of
     the Operative Documents or Hughes Agreements to which it is a party or (2)
     of such preempted or interrupted Transponder to meet the Transponder
     Performance Specifications upon the cessation of such preemption or
     interruption or otherwise cause an Adverse Effect to Lessor's (or to Owner
     Participant's) interest in such Transponder upon the expiration or
     termination of the Lease; (b) such preemption or interruption shall not
     commence or be continuing at any time during the final 720 days of the
     Basic Term or during any Renewal Term; (c) at the time such preemption or
     interruption ceases, such Transponder meets the applicable Transponder
     Performance Specifications; and (d) Lessee (and Seller, if the two parties
     shall be different entities) shall deliver to Lessor an Officer's
     Certificate (or Officer's Certificates, if applicable) (1) prior to such
     preemption or interruption (A) confirming the statement set forth in clause
     (a) above, (B) that, based on information available to Lessee at such time,
     Lessee reasonably believes that the Transponder will be capable of meeting
     the Transponder Performance Specifications therefor upon cessation of such
     preemption or interruption and (C) that Lessee intends to cause such
     preemption or interruption to cease prior to the final 720 days of the
     Basic Term and (2) upon the cessation of such preemption or interruption,
     confirming that the preempted or interrupted Transponder meets the
     Transponder Performance Specifications. At such time as any of the
     foregoing conditions is not met, then the Confirmed Failure of such
     Transponder shall, if the other conditions for a Confirmed Failure are

     so long as this Lease shall be in effect with respect to any Transponder
     and so long as no Event of Default shall have occurred and be continuing,
     to exercise in the name of and on behalf of Lessor, the right and power to
     deal with the Seller and Hughes Services under the Hughes Agreements and
     any other manufacturer or supplier of such Transponder or any other users
     of the transponders on the Satellite including, without limitation, the
     right to demand, receive, accept and retain all services, tests, inspection
     rights, reports and other data and services with respect to such
     Transponder as provided in the Purchase Agreement and the Service
     Agreement, and the right to enforce (by legal action or otherwise) or to
     elect not to enforce (except in such manner as would have a material
     adverse effect on Lessor's interest in the Transponders upon expiration or
     termination of the Lease) against such Seller, Hughes Services, other
     manufacturer or supplier or other user all rights, powers and privileges of
     Lessor, and to receive all benefits (subject to Sections 12(b), 12(c) and
     12(d)) of Lessor with respect to Seller, Hughes Services, such other
     manufacturer or such supplier or such other user, under any express or
     implied warranty or indemnity or other provisions of the Hughes Agreements
     or substitute agreements in effect, pursuant to Section 7(b) or otherwise,
     including, without limitation, the right to enforce (or not enforce (except
     in such manner as would have a material adverse effect on Lessor's interest
     in the Transponders upon the expiration or termination of the Lease)) and
     the right to obtain and retain the benefits of, all rights and claims of
     Buyer under the Purchase Agreement or of Owner under the Service Agreement;
     provided that, notwithstanding any term or provision of this Section
     5(b)(ii) to the contrary, Lessor and Owner Participant shall retain the
     right to any Excepted Payment owing to either of them, respectively.

          (iii) If, notwithstanding the foregoing, Lessor receives any payment
     of any kind whatsoever under the Purchase Agreement or the Service
     Agreement during the Lease Term to which Lessee is entitled pursuant to
     Section 5(b)(ii), Lessor shall upon receipt remit to Lessee the full amount
     of the payment received by it under the Purchase Agreement, or the Service
     Agreement, as the case may be; provided that no Payment Default, Bankruptcy
     Default or Event of Default shall have occurred and be continuing; provided
                                                                        --------
     further, however, that Lessor shall promptly remit such amounts to Lessee
     -------  -------
     at such time as no Payment Default, Bankruptcy Default or Event of Default
     is continuing.

     SECTION 6. Liens; Quiet Enjoyment; Assignment and Sublease.
                ----------------------------------------------- 

          (a) Liens. Lessee shall not directly or indirectly create, incur,
              -----
assume or suffer to exist any Lien on or with respect to any Transponder, the
Lessor's Estate or the Indenture Estate, or title thereto or any interest
therein, except Permitted Liens. Lessee's obligations under this Section 6(a)
with respect to any Lien, other than Owner Participant Liens or Lessor Liens, on
any Transponder arising prior to the termination of this Lease shall survive
such termination.

          (b) Quiet Enjoyment. So long as no Event of Default shall have
              ---------------
occurred and be continuing, as between Lessee and Lessor, Lessee shall have the
exclusive rights to possession and control of each Transponder and Lessor shall
not take any action that interferes with the quiet enjoyment of the use or non-
use of any Transponder by Lessee, and Lessee shall have the right to use or not
use such Transponder in its sole discretion.

          (c) Use Agreements. So long as no Lease Rental Payment Default,
              --------------
Bankruptcy Default or Event of Default shall have occurred and be continuing,
Lessee may, without the consent of or prior notice to Lessor, assign its
leasehold interest in whole or in part (including any of Lessee's rights

                                       9
<PAGE>
 
or options hereunder) in this Lease (a "Lease Assignment") and Lessee may
sublease, license, enter into short term or long term service contracts with any
Person (including, without limitation, to a "tax-exempt" entity as defined in
Section 168(h) of the Code), transfer Control of, or permit Seller or any other

occasional use service contract for the provision of part-time, occasional use
transponder capacity on available Ku-band or C-band transponders on satellites,
including the Satellite, owned or operated by Lessee or any Affiliate thereof
and not expressly required to be made available using any of the Transponders
leased hereunder (an "Occasional Use Service Contract")), on and subject to the
following terms and conditions:

           (i) such Use Agreements shall expressly provide that the rights of
     any sublessee, assignee, user or operator thereunder (collectively, "User")
     are subject and subordinate to all the terms and conditions of this Lease,
     including, without limitation, Lessor's right to repossess any Transponder
     and terminate such Use Agreements upon the occurrence of an Event of
     Default or other termination of this Lease, except that any Use Agreement
     with a term of one (1) year or less shall not be required to be so subject
     and subordinate, so long as, if entered into during the last year of the
     Basic Term or First Renewal Term (as applicable), the term of such Use
     Agreement does not extend beyond such Basic Term or First Renewal Term (as
     applicable);

          (ii)  Lessee shall remain primarily liable to Lessor for the
     performance of all of the terms of this Lease to the same extent as if such
     Use Agreements had not occurred;

          (iii) such Use Agreements shall not be in violation of Applicable Law
     and the terms and conditions thereof shall not be inconsistent with the
     terms of this Lease, provided that the term thereof (as well as the term of
     any Existing Lease (as defined below) set forth in Exhibit C hereto) may
     extend beyond the expiration of the Lease Term, subject to the provisions
     of Section 6(c)(i) above and Section 6(e); and

          (iv)  such Use Agreements shall prohibit the User from entering into
     any Further Use Agreements without obtaining (x) the written consent of
     Lessee and (y) an agreement by any such User further transferring its
     rights to comply with the terms and conditions of this Section 6(c),
     including, without limitation, the requirement that any such Further Use
     Agreement be expressly subject and subordinate to this Lease to the same
     extent as such Use Agreement.

In addition, no Lease Assignment shall be made unless: (i) assignee executes an
assignment and assumption agreement reasonably satisfactory to Lessor, which
agreement shall include the agreement therein that references in the Lease to
"Lessee" shall include, where appropriate, HCG, assignee or both, including,
without limitation, in the context of provisions concerning Events of Default;
(ii) with respect to the assignment of any of Lessee's technical obligations
hereunder, assignee shall be technically qualified to perform such

respect to the Transponders only, only to the extent such security interest was

the Indenture shall be taken and an executed chattel paper original counterpart
of any such assignment agreement shall be delivered by Lessee to the Indenture
Trustee.

     Subject to the provisions of this Section 6(c) and the Hughes Agreements,
Lessee may render any communications service, so long as the foregoing
provisions of this Section 6(c) shall apply, and Lessee or any Affiliate thereof
may provide Transponder or Transponders capacity by Lessee or any Affiliate of
Lessee to any of their respective customers in the ordinary course of their
respective businesses; provided that no rendering of any such communications
service or the providing of Transponder or Transponders capacity, and neither
the entering into or performing of any agreement related thereto, shall operate
to reduce, excuse or in any way affect the obligations of Lessee hereunder and
under the other Operative Documents or the Hughes Agreements to which it is a
party and as to which Lessee will remain primarily liable.

     During the Lease Term and while Series G Notes are outstanding, if at any
time both the Moody's Credit Rating and Standard & Poor's Credit Rating of
Guarantor fall below Investment Grade, then within thirty (30) days following
the date Lessee shall have Actual Knowledge that the foregoing condition exists,
Lessee shall execute and deliver to Lessor an assignment agreement (in form and
substance reasonably acceptable to Lessor) assigning to Lessor as additional
security for all of Lessee's payment obligations hereunder its rights under all
Use Agreements (other than any Occasional Use Service Contract) then in
existence and thereafter arising (the "Assignment Agreement"), except that
Lessee shall not be required to obtain a User's acknowledgement or consent nor
to notify (and in connection therewith, Lessor hereby agrees not to notify or
otherwise contact) any User of such assignment unless an Event of Default shall
have occurred and be continuing. The Assignment Agreement shall provide that
Lessee shall remain liable to User to perform its obligations under such Use
Agreement and Lessor shall have no obligations thereunder (other than
obligations expressly assumed by Lessor). The foregoing notwithstanding, if
Lessee shall execute and deliver the Assignment Agreement and subsequently the
condition set forth above requiring such assignment shall cease to exist, then,
effective on the date such condition shall cease to exist, the Assignment
Agreement shall automatically terminate by its terms and such Assignment
Agreement shall be of no further force or effect.

     (d) Existing Leases. Lessee hereby represents and warrants to and for the
         ---------------
benefit of Lessor and the Owner Participant that as of the date hereof: if HCG
is a party to any Use Agreement (an "Existing Lease") on any Transponder, then
none of the Existing Leases, including any renewal options thereunder, has a
term that extends beyond the expiration of the Basic Term, and all such Existing
Leases satisfy the requirements for Use Agreements set forth in Section 6(c).

     (e) Return of Transponders. (i) Subject to Section 6(c)(i), any Use
         ----------------------
Agreement may by its terms extend, or be extended by the User, beyond the Lease
Term and (ii) any Existing Lease may be extended by the user or sublessee under
such Existing Lease (a "Sublessee") beyond the Lease Term (a Transponder with
respect to which such Use Agreement or Existing Lease provides for such
extension, being referred to herein as a "Selected Transponder"), provided that
each Transponder (including, but not limited to, any Selected Transponder)
shall, at the time of Redelivery to Lessor pursuant to Section 10, be free and
clear of any continuing rights of or obligations to any User, Sublessee or other
Person, unless Lessor shall otherwise expressly agree in writing at the request
of Lessee.

     SECTION 7. Operation; Maintenance; Compliance with Law; Location of

     During the Lease Term with respect to any Transponder:

     (a) Operation. Subject to Section 5(b)(ii), Lessee shall observe and
         ---------
perform each and every obligation (and shall exercise all rights where failure
to do so would have a material adverse effect

                                      11
<PAGE>
 
on Lessor's interest in the Transponders upon the expiration or termination of
the Lease) of Buyer under the Purchase Agreement and Owner under the Service
Agreement to the extent the same relate to such Transponder, and shall keep the
same in full force and effect. Lessee shall not use any Transponder during the
Lease Term or authorize any third party to use such Transponder in breach of the
Purchase Agreement, the Service Agreement or any Applicable Laws applicable to
Lessee, Lessor (in its capacity as such Transponder owner without regard to
Applicable Laws applicable to Lessor solely because of its being engaged in a
regulated activity of any type other than the owning and leasing of the
Transponder), Owner Participant (in its capacity as such Transponder owner
without regard to Applicable Laws applicable to Owner Participant solely because
of its being engaged in a regulated activity of any type other than the owning
and leasing of the Transponder), such third party or such Transponder (in each
case, other than Applicable Laws as to which noncompliance would not have an
Adverse Effect), or in violation of any authorization relating to such
Transponder or the Satellite or Lessee issued by any Governmental Authority
having jurisdiction over such Transponder, the Satellite or Lessee or of
applicable insurance provisions (if insurance is then required to be maintained
pursuant to Section 9), other than (i) any provision of such Applicable Law,
authorization or insurance as to which noncompliance would not have an Adverse
Effect or (ii) unless the validity of such Applicable Law or authorization is
being contested in good faith and by appropriate proceedings (but only so long
as such proceedings do not involve any risk of civil or criminal liability to
Lessor, Owner Participant or the Indenture Trustee, and do not involve any
material danger of the sale, forfeiture, loss or diminution in value of such
Transponder or the rights of Lessor or Owner Participant or the Indenture
Trustee under any Hughes Agreement or any Operative Document and adequate
reserves with respect thereto shall have been established in accordance with
GAAP). As used herein, "Adverse Effect" shall mean that which would materially
adversely affect the business, operations or properties of GMHE on a
consolidated basis or involve any material danger (x) of the loss of any FCC
authorization to operate the Satellite or maintain it in the orbital location
permitted by Section 7(d), (y) of any material adverse effect on the ability of
Lessee to perform its obligations hereunder and under the Purchase Agreement or
of the sale, forfeiture, loss or diminution in value of any Transponder, or (z)
of the imposition of criminal or civil liability on the Lessor, the Owner
Participant or the Indenture Trustee.

     (b) Maintenance. Lessee hereby agrees to require Hughes Services to fulfill
         -----------
all of its obligations under the Service Agreement. Lessee, as Seller, shall
fulfill all of its obligations under the Purchase Agreement. Lessee will pay to
Hughes Services on behalf of Lessor an amount equal to all payments required to
be made by Lessor during the Lease Term to Hughes Services under the Service
Agreement as Supplemental Rent pursuant to Section 3(c)(iii), and will on behalf
of Lessor perform all other obligations thereunder required to be performed by
Lessor, with respect to such Transponder during the Lease Term. So long as
during the Lease Term the Service Agreement or a Substitute Service Agreement
shall have remained in full force and effect and Hughes Services (or a
Substitute Service Provider (as defined below), if applicable) shall have
performed all of its obligations thereunder with respect to such Transponder,
all maintenance, management and monitoring responsibilities of Lessee in
connection with such Transponder shall be deemed fulfilled, and Lessee shall
have no additional independent obligations hereunder relating thereto.

     In the event that at any time during the Lease Term the Service Agreement
shall no longer be in full force and effect or Hughes Services shall fail to
perform its obligations thereunder with respect to such Transponder, Lessee, at
its expense, shall maintain, manage and monitor, or cause to be maintained,
managed and monitored, the Satellite and such Transponder in good working order
and repair, ordinary wear and tear excepted, (i) in accordance with the higher
of (A) customary industry standards employed by owners of Ku-Band or C-Band
transponders, as applicable, on domestic communications satellites or (B)
standards at least equal to those used by Hughes Services or any of its

                                      12
<PAGE>
 
Affiliates prior to such failure of performance for other transponders on the
Satellite or on another similar satellite owned, leased or operated by Hughes
Services or any of its Affiliates (if at the time Hughes Services or any
Affiliate thereof maintains, manages or monitors satellites similar to the
Satellite for similar commercial purposes); (ii) in compliance with all
Applicable Laws (other than Applicable Laws as to which noncompliance would not
have an Adverse Effect); and (iii) in accordance with all applicable
requirements of any insurance policy then in effect that is required by Section
9 hereof. The foregoing notwithstanding, if, with respect to any Transponder,
Contractor or Substitute Service Provider is unable temporarily to perform its
maintenance obligations under the Service Agreement or any Substitute Service
Agreement due to any Force Majeure Event, then, provided such temporary failure
to perform does not cause a permanent material diminution in the value of such
Transponder and is capable of cure before any such permanent diminution in value
would result, such failure shall not constitute a breach of Lessee's obligations
under this Lease.

     Without limiting the generality of the foregoing, at any time during the
Lease Term, if the Service Agreement shall not be in effect, Lessee will arrange
for Lessor to enter into and Lessee will keep in full force and effect for the
remainder of the Lease Term an agreement for the provision of services (the
"Substitute Service Agreement") comparable to those to be provided by Hughes
Services under the Service Agreement at a reasonable cost with a sound and
reputable service provider, which may or may not be an Affiliate of Hughes
Services (the "Substitute Service Provider"), and which such provider shall be
reasonably acceptable to Lessor. If Lessor enters into a Substitute Service
Agreement, it will assign its rights under such agreement to Lessee during the
Lease Term on the terms and conditions contained in Section 5(b)(ii).

     (c) Compliance with Law. During the Lease Term with respect to any
         -------------------
Transponder, Lessee or Contractor shall have and maintain all permits, licenses
and approvals required by the FCC or under any Applicable Law to operate the
Satellite and such Transponder and shall satisfy the requirements of the FCC and
any statute, regulation or order applicable to operators, users or lessees of
such Transponder; provided, however, that Lessee shall not be deemed to have
                  --------  -------
breached the foregoing covenant unless such non-maintenance or non-satisfaction
would have an Adverse Effect. To the extent permitted by law, Lessee or any
Affiliate thereof shall prepare and file in timely fashion, or, where Lessor,
Owner Participant or Indenture Trustee shall be required so to file, prepare and
deliver to such Person within a reasonable time prior to the date for filing,
any reports with respect to any Transponder which are required to be filed with
any Governmental Body during the Lease Term for such Transponder. Lessor shall
notify Lessee promptly after Lessor has Actual Knowledge of any reports or
filings required of Lessor by law in connection with its ownership of the
Transponders; provided, however, that Lessor shall not incur any liability to
              --------  -------
Lessee for failure so to notify Lessee. If Lessee shall fail to timely prepare,
deliver or file any such report solely as a result of the failure of Lessor,
Owner Participant or Indenture Trustee timely to provide Lessee with (i) any
information required in such report which is in the possession of Lessor, Owner
Participant or Indenture Trustee and is not reasonably available to Lessee or
(ii) notice of the requirement of such report if such report is required as to
Lessor, Owner Participant or Indenture Trustee for any reason other than such
Person's interest in the Transponder or Transponders then subject to this Lease,
Lessee shall incur no liability to any such Person failing to provide such
information or notice to the extent such liability is incurred by the failure to
provide such information or notice (unless Lessee already had Actual Knowledge
of such requirement, Lessee fails to request such information from such Person
and such failure has an Adverse Effect). Lessor hereby appoints Lessee its
attorney-in-fact, to the extent permissible by Applicable Law, to execute such
reports in the name of Lessor and to file such reports, and Lessor shall
cooperate in furnishing Lessee such information as is available to it which must
be included in such reports. Upon demand, Lessee shall reimburse Lessor, Owner
Participant or Indenture Trustee on an After-Tax Basis for any reasonable 
out-of-pocket costs

                                      13
<PAGE>
 
incurred by each such Person, respectively, in connection with the preparation
and filing of any such reports. Lessee shall, on a periodic basis, furnish
Lessor, Owner Participant or Indenture Trustee with a copy of all reports filed
by Lessee on behalf of any such Person pursuant to this Section 7(c).

     (d) Location of Satellite. During the Lease Term, Lessee shall not move (or
         ---------------------
cause or suffer to be moved) or seek to move the Satellite to an orbital
location different from 91 degrees West Longitude for the remaining useful
commercial life of such Satellite (the "Permanent Orbital Location"); provided,
                                                                      --------
however, that Lessee (i) may, and shall be obligated to, move the Satellite at
- -------
any time or times if required to comply with a requirement of the FCC (an "FCC
Ordered Move") and (ii) may seek to move, and may move, the Satellite as part of
an overall industry process which will increase or decrease the number of, or
reallocate the, available orbital locations and which involves a substantial
number of satellites being moved in a coordinated manner and which shall not
involve movement of the Satellite in excess of 3 degrees longitude from the
Permanent Orbital Location. Neither Lessee nor any of its Affiliates shall seek
any order or approval from the FCC requiring or allowing the movement of the
Satellite other than pursuant to clause (ii) of the proviso to the immediately
preceding sentence.

     (e) Substitution of Transponder. Lessee shall have the right, in its
         ---------------------------
discretion, subject to the conditions set forth in this Section 7(e) to
substitute (a "Substitution"), from time to time during the Lease Term, for any
Transponder leased hereunder another transponder of the same type (including,
without limitation, with respect to preemptibility) aboard the Satellite (or
aboard Galaxy IV) (a "Replacement Transponder"); provided, however, that the
                                                 --------  -------
maximum aggregate number of Substitutions cannot exceed 50% (rounded downward
but not less than one) of the number of Transponders subject to the Lease as of
the Execution Date, exclusive of any transponder substituted in connection with
the occurrence of an Event of Loss with respect to a Transponder as permitted by
Section 12(b). Upon fulfillment of the conditions specified in this Section
7(e), such Replacement Transponder shall be conveyed by Lessee to Lessor and
leased to Lessee hereunder.

     The Substitution of a transponder pursuant to this Section 7(e) (or Section
12(a)) shall be subject to fulfillment of the following conditions precedent on
the date of the proposed Substitution at Lessee's sole cost and expense (and, in
the case of clauses (iii), (iv), (v), (vi), (vii), (ix), (x) (if applicable),
(xi) and (xiii) to the reasonable satisfaction of Lessor): (i) no Bankruptcy
Default or Event of Default shall have occurred and be continuing or will exist
immediately following the proposed Substitution; (ii) on the date of such
Substitution, the Replacement Transponder (A) shall meet the applicable
Transponder Performance Specifications set forth in Appendix D-1 or D-2, as
applicable, to the Purchase Agreement, (B) shall have a remaining useful
commercial life equal to or greater than the Transponder it is replacing, and
(C) a C-Band transponder shall only be substituted for a C-Band Transponder and
a Ku-Band Transponder for a Ku-Band Transponder and a 27 MHz transponder shall
not be substituted for a 54 MHz Transponder, and, in each case, such Replacement
Transponder shall have the same or greater value, utility and estimated residual
value as the Transponder it is replacing (all of (A), (B) and (C) as determined
pursuant to the Appraisal Procedure, performed by an appraiser selected by
Lessor within ten (10) Business Days of written notice from Lessee of a proposed
Substitution (or, in the absence of such selection by Lessor, as selected by the
Lessee) from the "Appraiser List" (attached hereto as Item 1 to Exhibit A (a
"Selected Appraiser")), which appraisal shall be performed within 30 days of the
selection of the Selected Appraiser); (iii) Lessor shall have received a bill of
sale substantially in the form of the Bill of Sale conveying title to such
Replacement Transponder to Lessor; (iv) if so requested by Lessor, or for so
long as the Indenture shall be in effect by Indenture Trustee, Lessee shall have
entered into a Lease Supplement covering such Replacement Transponder and, if so
requested by Indenture Trustee, Lessor shall have delivered an Indenture
Supplement to Indenture Trustee; (v) Lessor shall receive good and marketable
title to such Replacement Transponder free and

                                      14
<PAGE>
 
clear of all Liens other than Permitted Liens of the type discussed in clauses
(a) and (b) of the definition thereof; (vi) such Replacement Transponder shall
be covered by an assignment and consent instrument similar in form and substance
to the Consent and Agreement; (vii) Lessee shall have made arrangements
reasonably satisfactory to Lessor for Lessor to enter into the Service Agreement
or the Substitute Service Agreement or, if not then in effect, a service
agreement reasonably acceptable in form and substance to Lessor with respect to
the Replacement Transponder; (viii) Lessee shall have delivered to Lessor a
certificate from Lessee's President or Chief Financial Officer, which shall be
conclusive on the issue, stating that such Substitution is required for a bona
fide business purpose and is not being done primarily to obtain alternative
financing on such Transponder; (ix) Lessee shall have delivered to Lessor a
certificate from an officer of Lessee that the Substituted Transponder meets the
required standards set forth in (A), (B) and (C) of clause (ii), above; (x) in
the case of a Replacement Transponder aboard Galaxy IV, Lessee and Lessor shall
have entered into a transponder purchase agreement, transponder service
agreement and lease agreement covering such Replacement Transponder on terms
substantially similar to those contained in the Purchase Agreement, Service
Agreement and this Lease, respectively, such agreements modified only to reflect
the differences in the orbital location, useful commercial life and other
attributes unique to Galaxy IV, the transponders thereon, and then-existing
contractual commitments to owners of any such transponders on Galaxy IV,
provided that such then-existing contractual commitments are substantially
similar to the contractual commitments to owners of transponders on the
Satellite (each such agreement to be deemed for all purposes thereafter, a
Hughes Agreement or Operative Document, as applicable); (xi) Owner Participant
shall have received from Independent Tax Counsel a tax opinion to the effect
that the Owner Participant is not incurring additional income tax risk as a
result of such Substitution or, in lieu of such tax opinion, and provided there
is, in the opinion of Independent Tax Counsel, a reasonable basis for taking the
reporting position requested by Lessee, a tax indemnity by Lessee reasonably
satisfactory to Owner Participant; and (xii) so long as the Indenture is in
effect, the provisions of Sections 9(e) and 15(b) of the Indenture shall have
been satisfied; and (xiii) an opinion of counsel delivered to Lessor as to the
enforceability of the agreements referred to in clause (x) above, subject to
customary exceptions. Lessor shall cause Independent Tax Counsel to determine,
within five (5) Business Days of Lessee's written notice to Lessor of Lessee's
intent to exercise the foregoing Substitution right, whether it can provide the
tax opinion referred to in clause (xi), above. Owners of transponders on the
Satellite owning, in the aggregate, two-thirds or more of those transponders on
the Satellite owned by Lessor or by Owners pursuant to any Other Purchase
Agreement shall have the right at any time to replace one or more of the
appraisers on the Appraiser List, or to supplement such list, with one or more
different or additional appraisers reasonably satisfactory to Lessee, but in no
event shall such list contain more than three appraisers at any time. The
Appraiser List shall be maintained exclusively for the purpose described in this
Section 7(e).

     Upon the fulfillment of the foregoing conditions, Lessor will Transfer to
Lessee all of Lessor's right, title and interest in and to the Transponder to be
replaced as is, where is, free and clear of all Lessor Liens and Owner
Participant Liens, but otherwise without warranty, and will deliver to Lessee
such instrument as Lessee shall reasonably request releasing such Transponder
from this Lease. Upon such Substitution for all purposes hereof, such
Replacement Transponder shall be deemed to be a "Transponder" hereunder.

                                      15
<PAGE>
 
     If, during the last 540 days of the Basic Term, Lessee shall exercise the
foregoing Substitution right, then Lessee shall be deemed to have provided the
Preliminary Notice with respect to the Replacement Transponder and Lessee shall
thereafter comply with the procedures set forth in Section 18 (the "Substitution
Election Requirement"), except that if, at any time prior to the last 570 days
of the Basic Term, Lessor shall have given written notice to Lessee negating any
such Substitution Election Requirement (the "Cancellation Notice"), then Lessee
shall be deemed not to have provided such Preliminary Notice upon exercising
such Substitution right and Lessee's purchase and Lease renewal notice rights
pursuant to Section 18(a) or 18(d) with respect to such Replacement Transponder
shall be deemed reinstated and unaffected hereby. Lessor shall, at any time
prior to the last 570 days of the Basic Term, have the right to (i) give written
notice rescinding any prior Cancellation Notice, in which case the Substitution
Election Requirement shall be automatically reinstated, or (ii) send out a new
Cancellation Notice after having rescinded a prior such Cancellation Notice.

     SECTION 8. Termination.
                -----------

     (a) Early Termination.
         -----------------

     (i) Provided that no Lease Rental Payment Default, Bankruptcy Default or
Event of Default shall have occurred and be continuing, in the event that Lessee
shall in good faith determine that the Transponders, in the aggregate, have
become uneconomic, obsolete or surplus to Lessee's requirements (as evidenced by
a resolution to such effect adopted by the Board of Directors of HCG), Lessee
shall have the option, during the Basic Term (and not during any Renewal Term),
upon furnishing a notice to Lessor and Indenture Trustee at least 180 days prior
to the effectiveness thereof to terminate this Lease with respect to all, but
not less than all, of the Transponders on any Rent Payment Date on or after the
fifth anniversary of the In-Service Date (the "Termination Date"). As a
condition to any transfer by Lessor of the Transponders or retention by Lessor
of the Transponders (each pursuant to this Section 8), any necessary regulatory
approvals in connection therewith shall have been obtained (Lessee hereby
agreeing to use reasonable best efforts to obtain or to assist Lessor in
obtaining such approvals).

     During the period from the giving of such notice of termination for the
Transponders until 60 days prior to the Termination Date, Lessee, as non-
exclusive agent for Lessor, shall use commercially reasonable efforts to solicit
unconditional cash bids from Persons other than Lessee or its Affiliates to
purchase such Transponders on the Termination Date, and Lessee shall, during the
period from the giving of such notice of termination until 60 days prior to the
Termination Date (as set forth in the preceding paragraph), from time to time at
the request of Lessor or Indenture Trustee, inform Lessor and Indenture Trustee
of the results of its efforts and shall certify to Lessor and Indenture Trustee,
at least 60 days prior to the Termination Date, the amount and terms of each
such bid which has theretofore been submitted and the name and address of the
party submitting such bid. Lessor and Owner Participant shall each have the
right to solicit bids or each to make its own bid, provided that any bid by
Lessor or Owner Participant shall be submitted to Lessee prior to the disclosure
by Lessee to Lessor or Owner Participant of any other bids, but shall be under
no duty to solicit bids or to inquire into the efforts of Lessee to obtain bids.
Each such bid (a) shall be for payment in full in cash and (b) shall not involve
any consideration to be received by Lessee or its Affiliates or be connected,
directly or indirectly, with any transaction between the purchaser and the
Lessee or its Affiliates, (collectively, a "Bona Fide Bid"). On or prior to the
40th day prior to the Termination Date, Lessee may (provided that Lessee has not
previously canceled a proposed termination except for a deemed cancellation as
provided in Sections 8(a)(ii) and 8(c) hereto), by notice to Lessor and
Indenture Trustee,

                                      16
<PAGE>
 
cancel the proposed termination of this Lease for the Transponders, whereupon
this Lease shall continue in full force and effect with respect to the
Transponders.

     If Lessee does not cancel such proposed termination as set forth in the
last sentence of the preceding paragraph and any Bona Fide Bids are received on
or prior to the 60th day before the Termination Date, Lessee's notice of
termination shall become irrevocable on the 10th Business Day prior to the
Termination Date and Lessor shall on the Termination Date, provided that the
conditions of subsection (b) have been fulfilled, sell such Transponders to the
bidder which shall have submitted the highest Bona Fide Bid for such
Transponders and which has not defaulted on its bid (or to the next successively
highest bidders, if any, which shall have submitted Bona Fide Bids, in the case
of a default by the prior bidder, provided such sale shall have been consented
to by Lessee if the Bona Fide Bid related thereto is for an amount less than the
applicable Termination Value for the Transponders) for such Transponders upon
receipt in immediately available funds of the amount specified in such bid. Such
funds shall be paid either to Indenture Trustee or to Lessor, as required
pursuant to the Indenture. All reasonable out-of-pocket costs and expenses
incurred by Lessor or Indenture Trustee including, without limitation,
attorneys' fees, in connection with any notice of termination, regardless of
whether a sale is completed or Lessee withdraws its notice of termination, shall
be paid by Lessee on an After-Tax Basis.

     (ii) If no sale of the Transponders shall have occurred in accordance with
Section 8(a)(i) on the Termination Date, or if all bidders having submitted Bona
Fide Bids for such Transponders that were for an amount at least equal to
Termination Value for the Transponders (or if for less than such Termination
Value, the sale to such bidder was consented to by Lessee) have defaulted on
such bids, then the Lease shall continue in full force and effect and the
termination notice given by Lessee shall be deemed to have been canceled by
Lessee. If no sale of the Transponders shall have occurred in accordance with
Section 8(a)(i), as a result of a default by Lessor in its obligation to sell
the Transponders in accordance with Section 8(b), then Lessor shall have been
deemed to have exercised its election to retain ownership of the Transponders
pursuant to Section 8(c) hereof.

     (iii) Notwithstanding anything to the contrary in this Section 8(a), if the
bidder to whom the sale would otherwise have taken place shall have defaulted on
its bid within the ten (10) Business Day-period ending on the Termination Date,
Lessee shall nonetheless make, on the Termination Date, (A) all the payments
specified in the first sentence of Section 8(b) (but not the payment called for
by the second sentence of Section 8(b)), and (B) payment of Termination Value
for the Transponders as of the Termination Date. Promptly thereafter, Lessor
shall use its reasonable commercial efforts to sell the Transponders to an
unaffiliated third party. Lessor shall retain the net proceeds of any such sale
in excess of Termination Value for such Transponders as of the Termination Date
and pay to Lessee the net proceeds of such sale up to but not exceeding
Termination Value for such Transponders as of the Termination Date within five
(5) Business days of receipt of the proceeds of such sale. Upon payment by
Lessee of all the amounts due pursuant to this Section 8(a)(iii), the obligation
of Lessee to pay Base Rent with respect to the Transponders and Supplemental
Rent, other than to pay Supplemental Rent attributable to acts, events or
conditions occurring or existing on or prior to such termination with respect to
the Transponders or as otherwise provided in the Tax Indemnification Agreement
with respect to a loss of FSC Benefits, shall terminate, the Transponders shall
no longer be subject to this Lease and the Lease Term with respect to the
Transponders shall end.

                                      17
<PAGE>
 
     (b) Termination Payments. As a condition to the obligation of Lessor to
         --------------------                                              
terminate the Lease and to sell the Transponders pursuant to Section 8(a) on the
Termination Date therefor, Lessee shall on the Termination Date pay to Lessor
the sum of (A) all amounts of Base Rent and Interim Rent for such Transponders
due and unpaid prior to such Termination Date and (B) in the event that the
Termination Date is a Rent Payment Date on which a Scheduled Rent payment
designated as an "arrears rent" on Schedule A hereto, as adjusted pursuant to
Section 12.05 or 12.06, subject to Sections 12.07 and 12.08, of the
Participation Agreement, as applicable, is due, the sum of any Scheduled Rent
with respect to such Transponders designated as an "arrears rent" on Schedule A
hereto, as adjusted pursuant to Section 12.05 or 12.06, subject to Sections
12.07 and 12.08, of the Participation Agreement, as applicable, and due on such
Termination Date, and the Rent Differential Amount with respect to such date, if
any, and (C) any other Rent then due with respect to such Transponders,
including an amount equal to Variable Amount, if any, on the outstanding Notes
(excluding Termination Value). In addition, Lessor shall retain the net proceeds
of such sale of the Transponders and Lessee shall pay to Lessor the excess, if
any, of Termination Value for the Transponders (computed as of the Termination
Date) over such net sales proceeds. Upon payment by Lessee of the amounts due
pursuant to this Section 8(b), the obligation of Lessee to pay Base Rent and
Supplemental Rent, other than to pay Supplemental Rent attributable to acts,
events or conditions occurring or existing on or prior to such termination with
respect to the Transponders or as otherwise provided in the Tax Indemnification
Agreement with respect to a loss of FSC Benefits, shall terminate, the
Transponders shall no longer be subject to this Lease and the Lease Term with
respect to the Transponders shall end.

     (c) Retention of Transponders by Lessor. If Lessee shall elect to terminate
         -----------------------------------
this Lease pursuant to Section 8(a), Lessor may, subject to Lessee's right to
cancel the proposed notice of termination, elect to retain rather than sell the
Transponders by giving irrevocable notice to Lessee and Indenture Trustee no
later than 45 days prior to the Termination Date. If Lessor so elects to retain
the Transponders, on the Termination Date (i) Lessor shall pay to Indenture
Trustee an amount equal to the unpaid principal amount and accrued interest on
the outstanding Notes and (ii) Lessee shall pay to Lessor or the Person entitled
thereto as provided in the Operative Documents (A)(i) all Base Rent with
respect to the Transponders due prior to the Termination Date and (ii) in the
event that the Termination Date is a Rent Payment Date on which a Scheduled Rent
payment designated as an "arrears rent" on Schedule A hereto, as adjusted
pursuant to Section 12.05 or 12.06, subject to Sections 12.07 and 12.08, of the
Participation Agreement, as applicable, is due, the sum of any Scheduled Rent
with respect to the Transponders designated as an "arrears rent" on Schedule A,
as adjusted pursuant to Section 12.05 or 12.06, subject to Sections 12.07 and
12.08, of the Participation Agreement, as applicable, due on such Termination
Date and the Rent Differential Amount with respect to such date, if any, and (B)
all other Rent (other than any amounts required to be paid by Lessee pursuant to
the second sentence of Section 8(b)) due and owing on or prior to the
Termination Date, including an amount equal to Variable Amount, if any, on the
outstanding Notes, (iii) this Lease and the obligations of Lessee hereunder
shall terminate, other than to pay Supplemental Rent attributable to acts,
events or conditions occurring or existing on or prior to such termination or as
otherwise provided in the Tax Indemnification Agreement with respect to a loss
of FSC Benefits, and (iv) Lessor shall execute and deliver to Lessee, at
Lessee's reasonable expense, such instruments as Lessee shall reasonably request
to evidence the termination of this Lease. In the event Owner Participant fails
to make funds available to Owner Trustee to enable Lessor to pay the amounts
specified in clause (i) of this Section 8(c) or Lessee fails to pay the amounts
specified in clause (ii) of such sentence, Lessee shall be deemed to have
canceled its notice of termination and the Lease shall continue in full force
and effect (and in the case of Lessor's failure to pay the amounts set forth in
clause (i), above, Lessee shall have the right to enforce the obligations of
Owner Participant as set forth in Section 5.02(j) of the Participation
Agreement).

                                      18
<PAGE>
 
     (d) No Duplication of Rent Differential Amount. In the event that a portion
         ------------------------------------------
of the Scheduled Rent due on any Termination Date is designated as an "arrears
rent" on Schedule A and there is also a payment of Scheduled Rent due on such
Termination Date that is not so designated, a portion of the Rent Differential
Amount with respect to such Termination Date shall be added to the Scheduled
Rent designated as an "arrears rent" due on such date and the remainder of such
Rent Differential Amount shall be taken into account in the computation of
Termination Value pursuant to the definition of Termination Value. It is
intended that the entire amount of the Rent Differential Amount due on such
Termination Date shall be allocated between the Scheduled Rent designated as an
"arrears rent" due on such date and the computation of Termination Value, as
appropriate and without duplication, in such manner as will preserve the Owner
Participant's Net Economic Return and comply with the minimum payment
requirement contained in Section 3(f) (it being understood that the entire
amount of such Rent Differential Amount shall be taken into consideration in
making such allocation).

     SECTION 9. Insurance.
                ---------

     (a) Non-Discrimination. Lessee shall maintain general liability insurance
         ------------------
and/or life or casualty insurance with respect to the Satellite and the
Transponders in such amounts, if any, that Lessee deems prudent and cost-
effective but, in any event, Lessee shall maintain such insurance for not less
than the amounts, and on terms and conditions no less favorable than the terms
and conditions that Lessee and its Affiliates customarily maintain for similar
events or occurrences with respect to similar transponders owned for tax or book
purposes or leased from third parties by Lessee or any of its Affiliates on
similar satellites (the "Hughes Customary Terms", which terms may include
deductibles customarily maintained by Lessee or its Affiliates), without
reference to any insurance which Lessee or any of its Affiliates is obligated to
maintain with respect to those transponders leased by any of Lessee's Affiliates
aboard the SBS-6 communications satellite pursuant to those certain Lease
Agreements between Satellite Transponder Leasing Corporation and Wilmington
Trust Company, each dated December 27, 1991 (the "SBS-6 Exception"); provided,
                                                                     --------
however, that the foregoing shall not require Lessee to maintain life or
- -------
casualty insurance for the Transponders in an amount in excess of Stipulated
Loss Value for such Transponders.

     (b) Requirement to Obtain and Maintain Life or Casualty Insurance. During
         -------------------------------------------------------------
the Lease Term with respect to any Transponder, if at any time both of the
Moody's Credit Rating and the Standard & Poor's Credit Rating of Guarantor fall
below Investment Grade, then, within thirty (30) days following the date that
Lessee shall have Actual Knowledge that the foregoing condition exists, Lessee
shall obtain and maintain, for the period that such condition continues to
exist, life or casualty insurance with respect to the Transponders, on the
Hughes Customary Terms, in an amount, if any, equal to Stipulated Loss Value for
the Transponders from time to time, without deductible amounts.

     (c) Letter of Credit. If at any time during the Lease Term, Lessee is
         ----------------
required to carry insurance against loss of or damage to the Transponders,
Lessee may, in lieu of or in combination with carrying such insurance, provide a
letter of credit reasonably acceptable to Lessor from an Eligible Bank which, in
combination with any insurance carried by Lessee, shall be in an amount
corresponding to the Stipulated Loss Value for the Transponders from time to
time less any deductible permitted pursuant to Section 9(a), if applicable.

     (d) Additional Insureds. All insurance policies, if any, carried in
         -------------------
accordance with this Article 9 and all policies taken out in substitution or
replacement for any such policies (i) shall name Lessor (in its individual
capacity and as Owner Trustee), Owner Participant, and (so long as the Indenture
shall be in effect) Indenture Trustee, as additional insureds, as their
respective interests may appear (but

                                      19
<PAGE>
 
without imposing upon any such parties any obligation imposed upon the insured,
including without limitation, the liability to pay the premium for such
policies) and in the case of life or casualty insurance pursuant to Section
9(b), Indenture Trustee (so long as the Indenture shall be in effect) and Lessor
shall be named as "loss payees", as their interests may appear; (ii) shall
provide that any loss (other than a loss under general liability insurance)
shall be adjusted by the Lessee with the insurance carriers and be payable to
Lessor (or, so long as the Indenture shall be in effect, the Indenture Trustee),
for application as provided in Section 12 hereof or Section 5.4 of the
Indenture; and (iii) shall provide that if such insurance is changed in any
material adverse respect in relation to the interests of Lessor or Owner
Participant (and for so long as the Indenture shall be in effect, Indenture
Trustee), or if such insurance is allowed to lapse for non-payment of premium,
or is invalidated by any action or inaction of Lessee or any other Person (other
than action or inaction by Lessor, Owner Participant or Indenture Trustee, as
the case may be), such change, lapse or invalidation shall not be effective as
to Lessor, Owner Participant and (so long as the Indenture shall be in effect)
Indenture Trustee for at least 30 days after receipt by Lessor, Owner
Participant and (so long as the Indenture shall be in effect) Indenture Trustee
of written notice from such insurers, their agents or Lessee of such lapse. Each
insurance policy provided under this Section 9 shall be primary without right of
contribution from any other insurance which is carried by Lessor, Owner
Participant or Indenture Trustee with respect to their respective interests as
such in the Transponders.

     (e) Separate Insurance. Nothing contained in this Lease shall prevent
         ------------------
Lessor, Owner Participant, Indenture Trustee or Lessee, each at its own expense
and for its exclusive benefit, from carrying excess life or casualty insurance
covering the Transponders in addition to the life or casualty insurance, if any,
carried by Lessee under Section 9(b) (any such additional life or casualty
insurance being herein called "Additional Insurance"); provided, however, that
                                                       --------  -------
Lessee shall not be entitled to obtain any such Additional Insurance for the
Transponders unless Lessee shall then maintain life or casualty insurance for
such Transponders if then required pursuant to Section 9(b) in an amount at
least equal to the Stipulated Loss Value for such Transponders from time to time
set forth in Schedule B corresponding to such date. If there shall be any
limitation with respect to the amount of Additional Insurance that Lessor, Owner
Participant, Indenture Trustee or Lessee may obtain, whether as a result of
market capacity or otherwise, then each such party shall have the right to
purchase an amount of Additional Insurance for the Transponders as its interests
may then appear. Prior to obtaining any Additional Insurance, Lessor, Owner
Participant or Indenture Trustee shall provide Lessee with reasonable notice of
the Additional Insurance (including the proposed terms thereof) intended to be
obtained by it, including evidence satisfactory to Lessee that such proposed
terms shall be consistent with the terms of such insurance as may be carried by
Lessee under this Article 9.

     SECTION 10. Redelivery.
                 ----------

     (a) Redelivery Terms. At the expiration or earlier termination of the Lease
         ----------------
Term with respect to any Transponder, if Lessee does not renew this Lease with
respect to such Transponder and does not purchase such Transponder, Lessee shall
at Lessee's cost and expense redeliver such Transponder to Lessor in the
condition required by Section 7 hereof including, without limitation, in the
location permitted by Section 7(d) hereof and, in connection with such
Redelivery Lessee shall supply Lessor with the name, last known address and
telephone number of the most recent Sublessee or other User (other than Users
under Occasional Use Service Contracts) with respect to such Transponder. In the
event of any Redelivery of any Transponder, Lessee shall execute and deliver to
Lessor an instrument substantially in the form of Exhibit B to this Lease that
shall constitute evidence of surrender by Lessee of all of Lessee's rights to
such Transponder under this Lease and the Hughes Agreements applicable thereto;
provided, however, that Lessee's Redelivery of any Transponder hereunder shall
- --------  -------
not by itself

                                      20
<PAGE>
 
affect the validity and effectiveness of the Purchase Agreement, Service
Agreement or any Substitute Service Agreement relating to such Transponder, as
applicable. At the time of any Redelivery, such Transponder shall be free and
clear of all Liens (other than Permitted Liens described in clause (a) or (b) of
the definition thereof, excluding Lessor Liens and Indenture Trustee Liens) and
free and clear of any right of any Person to use or access such Transponder
other than Lessor or Owner Participant unless Owner Participant shall consent to
a request by Lessee to recognize any right of any Person to use or access such
Transponder other than Lessor and Owner Participant; and Lessee shall be in
compliance with Sections 7(b) and (c).

          (b)  Decreased Value.  If, at the end of the Basic Term, Lessee shall 
               ---------------
return to Lessor any Transponder, and the estimated fuel remaining on the
Satellite at the Redelivery date (as reasonably determined by Lessee using
standard industry procedures) as indicated in an Officer's Certificate delivered
by Lessee to Lessor on such date is less than 50% of the amount of fuel
originally estimated by the Appraiser in the In-Service Date Appraisal as
necessary for the residual value of the Satellite to be as set forth in the In-
Service Date Appraisal (the "In-Service Date Projection"), then Lessee shall pay
to Lessor an amount (the "Decreased Value") equal to the excess of (1) the
estimated Fair Market Sales Value of such Transponder as of such Redelivery
date, based on the assumption that such Transponder had a remaining useful
commercial life equal to 50% of the In-Service Date Projection over (2) the Fair
Market Sales Value of such Transponder caused by such lower amount of fuel,
determined as of the Redelivery date (the "Decreased Value Payment"). Lessee
shall pay to Lessor the Decreased Value Payment upon the later of the Redelivery
date or five (5) days after the Decreased Value of such Transponder is
determined in accordance with the Appraisal Procedure (which procedure shall
commence not later than 120 days prior to Redelivery if the existence of a
condition requiring a payment of Decreased Value is ascertainable at such time
or as soon thereafter as is reasonably possible if it not so ascertainable).

          (c)  Priority List.  If at the end of the Lease Term, Lessee shall 
               -------------
return to Lessor any Transponder and such Transponder shall have a priority
lower than the priority therefor established on the Closing Date, then Lessor
shall (i) have the right to seek equitable remedies, including specific
performance, to require Lessee or Seller to reinstate such Transponder to the
Closing Date priority level, or (ii) be entitled only to receive from Lessee an
amount equal to the difference between (A) the Fair Market Sales Value of such
Transponder on the Redelivery date and (B) the estimated Fair Market Sales Value
of such Transponder on the Redelivery date based on the assumption that such
Transponder had the priority it had on the Closing Date. The foregoing market
values shall be determined pursuant to the Appraisal Procedure.

     SECTION 11.  Cooperation.
                  ----------- 

          (a)  Lessor's Efforts to Sell or Lease.  Lessee agrees that during 
               ---------------------------------   
the last 540 days of the Basic Term or any Renewal Term applicable to any
Transponder (unless Lessee has provided Lessor with the Preliminary Notice
stating that it will renew the Lease or purchase such Transponder pursuant to
Section 18 or 19, respectively, and in such case no Bankruptcy Default or Event
of Default shall have occurred and be continuing), it will cooperate in all
reasonable respects with efforts of Lessor to lease or sell such Transponder,
including aiding potential lessees or purchasers by providing all data relating
to maintenance and performance for inspection which Owner under the Service
Agreement and Buyer under the Purchase Agreement are entitled to receive or
inspect subject to any confidentiality requirement set forth in such agreements.
Further, Lessee shall notify existing users of such Transponder of the end of
the Lease Term and use reasonable best efforts to assist Lessor in obtaining any
necessary regulatory approvals to operate, lease or sell such Transponder, at
Lessor's reasonable cost and expense, on an After-Tax Basis to Lessee. In
addition, Lessee shall furnish to Lessor such information as it supplies to

                                      21
<PAGE>
 
potential lessees or purchasers of transponders that it owns or leases on the
Satellite or other similar satellites.

          (b)  Value and Useful Life Determinations.  Lessee shall provide 
               ------------------------------------   
Lessor at any time with information which, in the reasonable opinion of Lessor,
is necessary or material for Lessor to negotiate and reach an agreement for any
determination of Fair Market Sales Value, Fair Market Rental Value and estimated
remaining useful commercial life; provided, however, that Lessee shall not be
                                  --------  -------
required to disclose confidential information unrelated to the performance or
maintenance of the Transponders.

     SECTION 12.  Loss, Destruction, Condemnation or Damage.
                  -----------------------------------------

          (a)  Payment of Stipulated Loss Value.  If with respect to any 
               --------------------------------
Transponder an Event of Loss occurs, then Lessee shall forthwith (and, in any
event, within seven (7) days of such occurrence) give Lessor and Indenture
Trustee notice of such Event of Loss (the "Casualty Notice"), which notice shall
include, if applicable, Lessee's election to provide a Replacement Transponder
in accordance with the last sentence of this paragraph and shall also state
whether the proviso to this sentence shall be applicable by reason of Lessee's
having in force insurance against loss or damage to the Transponders, pursuant
to Section 9 or voluntarily, and on the Casualty Payment Date first occurring
not less than 30 days after the date of such notice, Lessee shall pay to Lessor
an amount equal to the sum of (x) the Stipulated Loss Value for the Transponder
due on such Casualty Payment Date and (y) the sum of (A) all amounts of Interim
Rent and Base Rent with respect to such Transponder due and unpaid prior to such
Casualty Payment Date, and (B) (i) at any time during the Interim Term or the
Basic Term, in the event that the Casualty Payment Date is a Rent Payment Date
on which a Scheduled Rent payment designated as an "arrears rent" on Schedule A
hereto, as adjusted pursuant to such Section 12.05 or 12.06, subject to Sections
12.07 and 12.08, of the Participation Agreement, as applicable, is due, the sum
of Scheduled Rent with respect to such Transponder designated as an "arrears
rent" on Schedule A hereto as adjusted pursuant to such Section 12.05 or 12.06,
subject to Sections 12.07 and 12.08, and due on such Casualty Payment Date and
the Rent Differential Amount with respect to such date, if any, or (ii) at any
time during a Renewal Term any Base Rent due on such Casualty Payment Date and
(C) any other Rent (including, without limitation, an amount equal to Variable
Amount) with respect to such Transponder due and unpaid as of such Casualty
Payment Date (including an amount equal to Break Funding Cost, if any);
provided, however, that if, with respect to such Transponder, Lessee shall have
- --------  -------                                                             
in force insurance against loss or damage to the Transponders, pursuant to
Section 9 or voluntarily, then subject to the provisions of Section 12(b),
Lessee shall pay to Lessor in immediately available funds on the Casualty
Payment Date first occurring not less than thirty (30) days after the date of
the Casualty Notice, the amount specified in clause (x) of this Section less the
amount of such insurance with respect to such Transponder and, within ten (10)
days after receipt of any such insurance proceeds (but in no event later than
120 days after the date of such Casualty Notice) the amount specified in clause
(x) of this Section to the extent not previously paid, and to the extent of any
such payment to be made from such insurance proceeds or otherwise after the
Casualty Payment Date referred to above, Lessee shall pay interest from such
Casualty Payment Date on such amount to but excluding the date of payment at the
Applicable Rate borne by each Series of Notes then outstanding as to which the
insurance proceeds shall be applied, and otherwise at the Prime Rate; provided,
                                                                      -------- 
further that, in the case of an Event of Loss of the type described in clause
- -------                                                                      
(f) of the definition thereof, the amount due on the applicable Casualty Payment
Date in accordance with clause (x) of this Section 12(a) shall be the higher of
Stipulated Loss Value and the Fair Market Sales Value for the Transponder
(determined pursuant to the Appraisal Procedure based on the assumption that the
Satellite had not been removed from orbit) on such Casualty Payment Date. In
lieu of making the foregoing payment, and so long as, but only so long as, no
Bankruptcy Default or Event

                                      22
<PAGE>
 
of Default has occurred and is continuing, Lessee may, at its option, notify
Lessor and Indenture Trustee of its intent to, and thereafter provide Lessor (on
the Casualty Payment Date first occurring not less than thirty (30) days after
the date of the Casualty Notice) with a Replacement Transponder, in accordance
with, and subject to, the provisions and the conditions in Section 7(e).

          Upon payment in full of all amounts due or the provision of a
Replacement Transponder pursuant to the preceding paragraph, Lessor (as seller)
shall transfer the Transponder suffering such Event of Loss to Lessee, free and
clear of all Lessor Liens and Owner Participant Liens, but otherwise without
warranty, the obligation of Lessee to pay Interim Rent and Base Rent with
respect to such Transponder shall terminate, but shall continue as to any
Replacement Transponder, such Transponder shall no longer be subject to this
Lease and the Lease Term with respect to such Transponder shall end, but shall
apply to any Replacement Transponder.

          (b)  Application of Payments upon an Event of Loss.  Subject to the 
               ---------------------------------------------   
provisions of Section 12(d), and notwithstanding any rights of Lessor as owner
of the Transponders, any payments received at any time by Lessor from any
Governmental Body or other Person as a result of the occurrence of an Event of
Loss with respect to a Transponder (including proceeds with respect to such
Transponder from insurance, if any, but excluding proceeds from Additional
Insurance with respect to such Transponder carried by Lessor, Owner Participant
or Indenture Trustee) shall be applied as follows:

               (i)    so much of such payments as shall not exceed the amount of
     Stipulated Loss Value, if any, required to be paid with respect to such
     Transponder by Lessee pursuant to Section 12(a) shall be applied in
     reduction of Lessee's obligation to pay such amount with respect to such
     Transponder if not already paid by Lessee, or, if already paid with respect
     to such Transponder by Lessee, shall be applied to reimburse Lessee for its
     payment of such amounts, or if Lessee shall have provided Lessor with a
     Replacement Transponder pursuant to Section 12(a), shall be paid to Lessee
     upon conveyance of such Replacement Transponder to Lessor; and

               (ii)   the excess, if any, of such payments with respect to such
     Transponder remaining thereafter shall be allocated between Lessor and
     Lessee as their respective interests may appear (except to the extent
     reflecting proceeds of insurance (other than additional insurance
     maintained by Owner Participant, Owner Trustee or Indenture Trustee), which
     shall be paid to and retained by Lessee).

          (c)  Application of Payments Not Relating to an Event of Loss.  In 
               --------------------------------------------------------   
the event of any loss, condemnation, confiscation, theft or seizure of, or use
of, or damage to, any portion of any Transponder not constituting an Event of
Loss, Lessee shall promptly notify Lessor and Indenture Trustee and all of
Lessee's obligations under this Lease with respect to such Transponder shall
continue to the same extent as if such event had not occurred. Subject to the
provisions of Section 12(d), and notwithstanding any implicit or express rights
of Lessor as owner of such Transponder, payments received at any time by Lessor
or Lessee from any insurer under insurance carried by Lessee from any
Governmental Body or from any other Person with respect to any loss,
condemnation, confiscation, theft or seizure of, or use of, or damage to, any
Transponder or any part thereof not constituting an Event of Loss shall be paid
to Lessor or Lessee, as their interests may appear.

          (d)  Applications During Default.  Any amount which may become 
               ---------------------------  
payable to Lessee pursuant to this Lease arising out of any insurance, warranty,
governmental award or otherwise shall not be paid to Lessee, or if it shall have
been paid to Lessee shall not be retained by Lessee, but shall be paid

                                      23
<PAGE>
 
to Lessor or Indenture Trustee, as the case may be, if at the time of such
payment a Payment Default, Bankruptcy Default or an Event of Default shall have
occurred and be continuing.  In such event, all such amounts shall be paid to
and held by Lessor or, to the extent required by the Indenture, Indenture
Trustee, in trust as security for the obligations of Lessee, Seller, Contractor
or Guarantor to make payments under this Lease and any other Operative Document
or Hughes Agreement or to pay Rent hereunder or, at the option of such holder,
applied by such holder toward payment of any such obligations of Lessee, Seller,
Guarantor or Contractor at the time due hereunder or under such other Operative
Document or Hughes Agreement.  At such time as there shall not be continuing a
Payment Default, Bankruptcy Default or an Event of Default all such amounts at
the time held by Lessor or Indenture Trustee, as the case may be, in excess of
the amount, if any, which Lessor or Indenture Trustee, as the case may be, shall
have elected to apply as above provided shall be paid to Lessee, Seller or
Contractor, as appropriate.

          (e)  No Duplication of Rent Differential Amount.  In the event that a 
               ------------------------------------------   
portion of the Scheduled Rent due on any Casualty Payment Date is designated as
an "arrears rent" on Schedule A and there is also a payment of Scheduled Rent
due on such Casualty Payment Date that is not so designated, a portion of the
Rent Differential Amount with respect to such Casualty Payment Date shall be
added to the Scheduled Rent designated as an "arrears rent" due on such date and
the remainder of such Rent Differential Amount shall be taken into account in
the computation of Stipulated Loss Value pursuant to the definition of
Stipulated Loss Value.  It is intended that the entire amount of the Rent
Differential Amount due on such Casualty Payment Date shall be allocated between
the Scheduled Rent designated as an "arrears rent" due on such date and the
computation of Stipulated Loss Value, as appropriate and without duplication, in
such manner as will preserve the Owner Participant's Net Economic Return and
comply with the minimum payment requirement contained in Section 3(f) (it being
understood that the entire amount of such Rent Differential Amount shall be
taken into consideration in making such allocation).

     SECTION 13. Merger, Consolidation.
                 --------------------- 

          Lessee shall not consolidate with or merge into any other Person or
convey, transfer or lease all or substantially all of its assets as an entirety
to any Person, unless:

               (i)    the successor entity formed by such consolidation or into
     which it is merged or the successor entity which acquires by conveyance,
     transfer or lease all or substantially all of its assets as an entirety
     shall be a corporation organized and existing under the laws of the United
     States of America, any State thereof or the District of Columbia which has
     a substantial part of its properties and assets located within, and
     operates substantially within, the United States of America, and which is
     qualified under the requirements of the FCC and any applicable statute,
     regulation or order to assume Lessee's obligations with respect to the
     Satellite and/or Transponders then subject to this Lease;

               (ii)   such successor corporation shall expressly assume in
     writing by instrument or instruments enforceable against it reasonably
     satisfactory in form and substance to Lessor and Owner Participant the due
     and punctual payment, performance and observance of all obligations of
     Lessee under this Lease and any other Operative Document or Hughes
     Agreement to which Lessee is a party in any capacity, with the same effect
     as if such corporation had originally been named Lessee herein or had been
     a party thereto;

                                      24
<PAGE>
 
               (iii)  immediately after giving effect to such transaction, no
     Bankruptcy Default or Event of Default shall exist and the Guarantee
     Agreement (or any successor agreement) shall be in full force and effect;
     and

               (iv)   Lessee shall have delivered to Lessor, Owner Participant
     and Indenture Trustee an opinion of counsel in scope and substance
     reasonably satisfactory to each stating that such consolidation, merger,
     conveyance, transfer or lease and the assumption agreement required by
     clause (ii) above comply with this Section 13.

          Upon any consolidation or merger, or any conveyance, transfer or lease
of all or substantially all of the assets of Lessee as an entirety in accordance
with this Section 13, the successor corporation formed by such consolidation or
into which Lessee is merged or to which such conveyance, transfer or lease is
made shall succeed to, and be substituted for, and may exercise every right and
power of, Lessee under the Operative Documents to which Lessee is a party in any
capacity with the same effect as if such successor corporation had been named
Lessee herein and therein.  No such conveyance, transfer or lease of all or
substantially all of the assets of Lessee as an entirety shall have the effect
of releasing Lessee or any successor corporation which shall theretofore have
become such in the manner prescribed in this Section 13 from its liability
hereunder or under the other Operative Documents or Hughes Agreement to which
Lessee is a party in any capacity.

     SECTION 14.  Reports.
                  ------- 

          (a)  Condition and Operation.  Lessor, Owner Participant and 
               -----------------------   
Indenture Trustee shall have the right to obtain and, following any such request
by any of them, Lessee shall provide or request to be provided, information
regarding the condition and state of repair of any Transponder then subject to
this Lease, compliance by Lessee with Sections 7 and 9 and performance of Seller
and Contractor under the Hughes Agreements (it being understood that information
with respect to the performance of Seller and Contractor shall be limited to
that made available pursuant to the Hughes Agreements), and the absence of any
Default or Event of Default or Event of Loss, or event which with the passage of
time or giving of notice or both would become an Event of Loss. Indenture
Trustee shall neither have any duty to make any inquiry nor incur any liability
obligation by reason of not making any such inquiry.

          (b)  Liens.  Lessee shall promptly (and in no event later than five 
               -----   
(5) Business Days) notify Lessor and Indenture Trustee after having obtained
Actual Knowledge of the attachment of any Lien which Lessee shall be obligated
to discharge or eliminate pursuant to Section 6 unless the same shall already
have been removed or discharged by Lessee.

     SECTION 15.  Events of Default.
                  ----------------- 

          Each of the following events shall constitute an Event of Default
(whether any such event shall be voluntary or involuntary or come about or be
effected by operation of law or pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation of any
Governmental Body or otherwise):

          (a)  Lessee shall fail to make any payment of Interim Rent, Base Rent,
Supplemental Rent pursuant to Section 3(b)(i)(A), Section 3(c)(ii) or Section
3(c)(iv), Termination Value, Stipulated Loss Value or EBO Amount when due and
such failure shall continue ten (10) Business Days; or

                                      25
<PAGE>
 
          (b)  Lessee shall fail to make any other payment of Rent when due and
such failure shall continue ten (10) Business Days after written notice thereof
by Lessor (or Indenture Trustee); or

          (c)  Other than with respect to any covenant of Lessee set forth in
Section 15.02(b) of the Participation Agreement, Lessee shall fail to perform or
observe in any material respect any covenant, condition or agreement to be
performed or observed by it under this Lease (other than Section 6(d) or 9(b)),
or Guarantor shall fail to perform or observe in any material respect any
covenant, condition or agreement to be performed or observed by it under the
Participation Agreement or the Guarantee Agreement or Lessee, Seller, Contractor
or HCG shall fail to perform or observe in any material respect any other
covenant, condition or agreement to be performed or observed by it under any of
the other Operative Documents or Hughes Agreements to which it is a party (other
than any such covenant, condition or agreement under the Tax Indemnification
Agreement not related to the payment of money thereunder, provided that the
                                                          --------
declaration of an Event of Default hereunder with respect to any such covenant,
condition or agreement shall be only upon the instructions of the Owner
Participant) and, in each such case, such failure shall have continued for
ninety (90) days after Lessee's receipt of written notice thereof from Lessor or
Indenture Trustee; provided, however, that if such failure is capable of cure
                   --------  -------
but cannot be cured by payment of money and cannot be cured by diligent efforts
within such 90-day period but such diligent efforts shall be properly commenced
within the cure period and Lessee is diligently pursuing, and shall continue to
pursue diligently, a remedy of such failure, the cure period shall be extended
for an additional period of time as may be necessary to cure, not to exceed an
additional 90 days; and provided, further however, that if Lessee shall fail to
                        --------  ------- -------                             
observe the covenant set forth in Section 5.01(p) of the Participation
Agreement, then, notwithstanding anything to the contrary in this Section 15(c),
such failure shall constitute an immediate Event of Default, without the
requirement of any lapse of time or notice thereof; or

          (d)  Any representation or warranty made by Lessee, Seller, HCG or
Contractor in any of the Operative Documents or Hughes Agreements to which it is
a party or in any written statement, report, schedule, notice or other writing
furnished by Lessee, Seller, HCG or Contractor in connection therewith (other
than any representation or warranty under the Tax Indemnification Agreement)
shall prove to have been inaccurate in any material respect at the time made;
provided, however, that if the representation or warranty was originally made 
- --------  -------
in good faith, an Event of Default shall not be deemed to exist unless the
inaccuracy materially adversely affects Lessor, Owner Participant or Indenture
Trustee and if capable of being cured, remains uncured for a period of ninety
(90) days after receipt by Lessee of written notice from Lessor or Indenture
Trustee of such inaccuracy; provided, however, that if such Default cannot be

     SECTION 16.  Remedies.  Upon the occurrence of any Event of Default and at 
                  --------   
any time thereafter so long as the same shall be continuing, Lessor may at its
option declare this Lease to be in default, and at any time thereafter Lessor
may do any of the following as Lessor in its sole discretion shall elect, to the
extent permitted by, and subject to compliance with any mandatory requirements
of, Applicable Law then in effect:

          (I)  Proceed by appropriate court action, either at law or in equity,
to enforce performance by Lessee or Guarantor of the applicable covenants of
this Lease or the Guarantee Agreement or to recover damages for the breach
thereof; or

          (II) By notice in writing terminate this Lease, whereupon all rights
of Lessee to the use of the Transponders or to purchase the Transponders
(whether or not Lessee shall have theretofore made the EBO Prepayment) shall
absolutely cease and terminate but Lessee shall remain liable as hereinafter
provided;

               (a)  Lessor, by notice to Lessee specifying a payment date not
     later than 180 days from the date of such notice, may require Lessee to pay
     to Lessor, and Lessee hereby agrees that it will pay to Lessor, on the
     payment date specified in such notice, as liquidated damages for loss of a
     bargain, and not as a penalty, and in lieu of any further payments of
     Interim Rent or Base Rent hereunder, an amount (reduced by any amounts
     previously paid by Lessee pursuant to Section 16(II)(c)) equal to the sum
     of (x) all unpaid Interim Rent or Base Rent payable or which would have
     been payable before the Casualty Payment Date next succeeding the date of
     payment specified in such notice and (y)(A) at any time during the Interim
     Term or the Basic Term, in the event that the Casualty Payment Date is a
     Rent Payment Date on which a Scheduled Rent designated as an "arrears rent"
     on Schedule A hereto, as adjusted pursuant to Section 12.05 or 12.06,
     subject to Sections 12.07 and 12.08, of the Participation Agreement, as
     applicable, is due, the sum of Scheduled Rent designated as an "arrears
     rent" on Schedule A hereto, as adjusted

                                      27

     pursuant to Section 12.05 or 12.06, subject to Sections 12.07 and 12.08, of
     the Participation Agreement, as applicable, and due on such Casualty
     Payment Date with respect to the Transponders and the Rent Differential
     Amount, if any, or (B) at any time during a Renewal Term, any Base Rent due
     on such Casualty Payment Date and (z) an amount equal to the excess (the
     "SLV Excess"), if any, of Stipulated Loss Value for the Transponders over
     either the EBO Amount (if Lessee shall have contemporaneously or previously
     made the EBO Prepayment) or zero (if Lessee shall not have
     contemporaneously or previously made the EBO Prepayment), which SLV Excess
     shall be calculated as of such Casualty Payment Date next succeeding the
     date of payment specified in such notice (unless such payment date occurs
     on a Casualty Payment Date, in which case such SLV Excess and such unpaid
     Interim Rent and Base Rent shall be computed as of such Casualty Payment
     Date), together with interest, if any, at the Applicable Overdue Rate on
     the amount of such Interim Rent and Base Rent and SLV Excess from the date
     as of which such SLV Excess is computed until the date of actual payment;
     and upon such payment of liquidated damages and all other Rent then due and
     payable by Lessee hereunder, Lessor shall transfer the Transponders
     (without any representation, recourse or warranty whatsoever, other than
     the absence of Lessor Liens or Owner Participant Liens) to Lessee and
     Lessor shall execute and deliver such documents evidencing such transfer as
     Lessee shall reasonably request, and Lessee shall indemnify Lessor on an
     After-Tax Basis for Lessor's reasonable expenses incurred in connection
     with such transfer.

               (b)  Lessor or its agent may sell the Transponders at public or
     private sale, as Lessor may determine, or otherwise may dispose of, hold,
     use, operate, keep idle, lease (whether for a period greater or less than
     the balance of what would have been the Basic Term or any Renewal Term, as
     the case may be) to others the Transponders, all on such terms and
     conditions and at such place or places as Lessor may determine and all free
     and clear of any rights of Lessee and of any claim of Lessee, in equity, at
     law or by statute (including, without limitation, any right or claim of
     Lessee that shall arise or shall have arisen in connection with Lessee's
     making or having made the EBO Prepayment), whether for loss or damage or
     otherwise and Lessee shall use its best efforts to obtain or assist Lessor
     in obtaining, any necessary regulatory approvals for Lessor to take any
     action pursuant to this Section 16(II)(b); provided, however, that (i) if
                                                --------  -------
     Lessor or its agent shall sell any Transponders, Lessee's obligation to pay
     Interim Rent and Base Rent with respect to any such Transponder sold
     hereunder for any period after the date of such sale shall terminate and
     such Transponder shall cease to be subject to this Lease from and after the
     date of such sale, and (ii) Lessee's obligation to pay Interim Rent and
     Base Rent for any period after Lessee shall have been deprived of control
     of the Transponder pursuant to clause (i) of this Section 16(II)(b) shall
     be reduced by the net proceeds, if any, received by Lessor from leasing the
     Transponder to, or otherwise permitting its use by, any Person other than
     Lessee fairly attributable to all or any portion of such period. In the
     event Lessor shall have sold any Transponder pursuant to this Section
     16(II)(b) (and prior thereto shall not have exercised its rights under
     Section 16(II)(c) hereof), Lessor may demand that Lessee pay Lessor and
     Lessee shall pay to Lessor, as liquidated damages for the loss of a bargain
     and not as a penalty, in lieu of all Interim Rent or Base Rent due after
     the date on which such sale occurs, an amount equal to the sum of (i) all
     unpaid Interim Rent and Base Rent payable or which would have been payable
     on or before the Casualty Payment Date next succeeding the date on which
     the sale occurs (unless such sale occurs on a Casualty Payment Date, in
     which case Interim Rent or Base Rent shall be computed as of such Casualty
     Payment Date) plus (ii) the amount, if any, by which the Stipulated Loss
     Value for such Transponder, computed as of the Casualty Payment Date
     immediately following the date on which such sale occurs (unless such sale
     occurs on a Casualty Payment Date, in which case as of such Casualty
     Payment Date), exceeds the net

                                      28

     proceeds of such sale (together with interest, if any, at the Overdue Rate
     on the amount of such Interim Rent and Base Rent and excess from the
     Casualty Payment Date as of which such Stipulated Loss Value is computed
     until the date of actual payment); provided, however, that in the event
                                        --------  -------
     that Lessee shall have theretofore made the EBO Prepayment, Lessor shall
     pay to Lessee an amount equal to the EBO Amount less such excess.

               (c)  Whether or not Lessor shall have exercised, or shall
     thereafter at any time exercise, any of its rights under Section 16(II)(b)
     hereof (other than a sale under Section 16(II)(b) hereof), Lessor may, at
     any time prior to the time that any Transponder shall have been sold or
     leased by Lessor pursuant to Sections 16(II)(a) or 16(II)(b) hereof, by
     written notice to Lessee requesting that the Fair Market Sales Value or
     Fair Market Rental Value of such Transponder be determined, demand that
     Lessee pay to Lessor, and Lessee shall pay to Lessor on the first Casualty
     Payment Date occurring at least ten (10) days after the determination of
     such Fair Market Sales Value or Fair Market Rental Value, as the case may
     be, each determined on an as is, where is basis, as the case may be, as
     liquidated damages for loss of a bargain and not as a penalty (in lieu of
     all payments of Interim Rent and Base Rent with respect to such Transponder
     becoming due for periods after the payment date), an amount equal to the
     sum of (i) all unpaid Interim Rent and Base Rent due before such Casualty
     Payment Date and (ii)(A) at any time during the Interim Term or the Basic
     Term, in the event that the Casualty Payment Date is a Rent Payment Date on
     which a Scheduled Rent designated as an "arrears rent" on Schedule A
     hereto, as adjusted pursuant to Section 12.05 or 12.06, subject to Sections
     12.07 and 12.08, of the Participation Agreement, as applicable, is due, the
     sum of Scheduled Rent designated as an "arrears rent" in Schedule A hereto,
     as adjusted pursuant to Section 12.05 or 12.06, subject to Sections 12.07
     and 12.08, of the Participation Agreement, as applicable, due on such
     Casualty Payment Date with respect to such Transponder and the Rent
     Differential Amount, if any, or (B) at any time during a Renewal Term, any
     Base Rent due on such Casualty Payment Date, and (iii) whichever of the
     following amounts Lessor, in its sole discretion, shall specify in such
     notice (together with interest on such amount at the Applicable Overdue
     Rate from the scheduled payment date to the date of actual payment): (x) an
     amount equal to the excess, if any, of the Stipulated Loss Value, computed
     as of such Casualty Payment Date, over the Fair Market Rental Value for
     such Transponder, valued on an as is, where is basis for the remainder of
     the Interim Term and the Basic Term or the remainder of the Renewal Term,
     as the case may be, after discounting such Fair Market Rental Value semi-
     annually (effective on the Rent Payment Dates) to present value as of the
     scheduled payment date at the rate of interest equal to the Applicable
     Overdue Rate; (y) an amount equal to the excess, if any, of such Stipulated
     Loss Value as of such Casualty Payment Date over the Fair Market Sales
     Value of such Transponder valued on an as is, where is basis or (z) an
     amount equal to the excess, if any, of (A) the present value computed as of
     such Casualty Payment Date of all installments of Scheduled Rent for the
     remainder of the Interim Term and Basic Term or Base Rent for the remainder
     of the Renewal Term, as the case may be, discounted semi-annually
     (effective on the Rent Payment Dates) to present value as of the scheduled
     payment date at the rate of interest equal to the Applicable Overdue Rate
     over (B) the present value, computed as of such Casualty Payment Date, of
     the Fair Market Rental Value of the Transponder for the remainder of the
     Interim Term and the Basic Term or of the Renewal Term, as the case may be,
     discounted semi-annually (effective on the Rent Payment Dates) to present
     value as of the scheduled payment date at the rate of interest equal to the
     Applicable Overdue Rate; provided, however, that, in the event that
                              --------  -------                         
     Lessee shall have theretofore made the EBO Prepayment, Lessor shall pay to
     Lessee an amount equal to the EBO Amount less the applicable excess, if
     any, referred to in clause (x), (y) or (z) above.

               (d)  For all purposes of this Section 16, in the event that a
     portion of the Scheduled Rent due on any Casualty Payment Date is
     designated as an "arrears rent" on Schedule A and there is also a payment
     of Scheduled Rent due on such Casualty Payment Date that is not so
     designated, a portion of the Rent Differential Amount with respect to such
     Casualty Payment Date shall be added to the Scheduled Rent designated as an
     "arrears rent" due on such date and the remainder of such Rent Differential
     Amount shall be taken into account in the computation of Stipulated Loss
     Value pursuant to the definition of Stipulated Loss Value. It is intended
     that the entire amount of the Rent Differential Amount due on such Casualty
     Payment Date shall be allocated between the Scheduled Rent designated as an
     "arrears rent" due on such date and the computation of Stipulated Loss
     Value, as appropriate and without duplication, in such manner as will
     preserve the Owner Participant's Net Economic Return and comply with the
     minimum payment requirement (it being understood that the entire amount of
     such Rent Differential Amount shall be taken into consideration in making
     such allocation).

All determinations of Fair Market Sales Value and Fair Market Rental Value
pursuant to this Section 16 shall be determined pursuant to the Appraisal
Procedure. No termination of this Lease, in whole or in part, or exercise of any
remedy under this Section 16 shall, except as specifically provided herein,
relieve Lessee of any of its liabilities and obligations hereunder, all of which
shall survive such termination, repossession or exercise of remedy. In addition,
Lessee shall be liable for any and all unpaid Supplemental Rent (including an
amount equal to Variable Amount) due hereunder before, after or during the
exercise of any of the foregoing remedies, including all reasonable legal fees
and other costs and expenses reasonably incurred by Lessor, Owner Participant or
Indenture Trustee by reason of the occurrence of any Event of Default or the
exercise of Lessor's remedies with respect thereto. At any sale of the
Transponders or any part thereof pursuant to this Section 16, Lessor, Owner
Participant or Indenture Trustee may bid for and purchase such property.

          Notwithstanding any provision in this Lease or any other Operative
Document, Lessee shall not cease to have the legal right to access any of the
Transponders unless and until Lessor shall give Lessee and Seller, at the time
when a notice of termination is given under the first sentence of clause (II)
above, 24 hours notice expressly demanding that Lessee surrender such right.

          To the extent permitted by, and subject to the mandatory requirements
of, Applicable Law, and except as otherwise specifically provided for in this
Lease, each and every right, power and remedy herein specifically given to
Lessor or otherwise in this Lease shall be cumulative and shall be in addition
to every other right, power and remedy herein specifically given or now or
hereafter existing at law, in equity or by statute, and each and every right,
power and remedy whether specifically herein given or otherwise existing may be
exercised from time to time and as often and in such order as may be deemed
expedient by Lessor, and the exercise or the beginning of the exercise of any
power or remedy shall not be construed to be a waiver of the right to exercise
at the same time or thereafter any other right, power or remedy. No delay or
omission by Lessor in the exercise of any right, remedy or power or in the
pursuit of any remedy shall impair any such right, remedy or power or be
construed to be a waiver of any default on the part of Lessee or to be an
acquiescence therein. No express or implied waiver by Lessor of any Event of
Default shall in any way be, or be construed to be, a waiver of any future or
subsequent Event of Default.

          Except to the extent provided for by the express terms of this Lease,
each of Lessor and Indenture Trustee and any Person claiming through either of
them, waives and agrees not to claim any amount under this Section 16 or
otherwise under this Lease in respect of incidental or consequential damages
incurred by it.

          To the extent permitted by Applicable Laws, Lessee hereby waives any
rights now or hereafter conferred by statute or otherwise that may require
Lessor, its successors or assigns to mitigate its damages in any particular
manner or that may otherwise limit or modify any of the rights or remedies of
Lessor under this Section 16, but nothing contained herein shall eliminate
Lessor's obligation to mitigate its damages as may be required by Applicable
Law.

     SECTION 17. Right to Perform for Lessee.
                 ---------------------------

          (a)    Right to Cure. If Lessee shall fail to make any payment of Rent
                 -------------                                    
to be made by it hereunder or shall fail to perform or comply with any of its
other agreements contained herein or in the Hughes Agreements relating to any of
the Transponders, Lessor or Owner Participant may (but shall not have any duty
to do so) itself make such payment or perform or comply with such agreement;
provided that nothing contained in this Section 17(a) shall be deemed to expand
in any way the rights of Lessor or Owner Participant under Section 16.1 of the
Indenture. The amount of any such payment and the amount of the reasonable
expenses of Lessor and Owner Participant incurred in connection with such
payment or the performance of or compliance with such agreement, as the case may
be, together with interest thereon at the Overdue Rate, shall be deemed
Supplemental Rent, payable by Lessee upon demand.

          (b)    Lessor is Lessee's Agent and Attorney. Without in any way
                 -------------------------------------                    
limiting the obligations of Lessee or Lessor hereunder, Lessee hereby
irrevocably appoints Lessor as its agent and attorney-in-fact hereunder, with
full power and authority at any time at which Lessee is obligated to deliver any
Transponder to Lessor, to demand and take such Transponder in the name and on
behalf of Lessee from whosoever shall be at the time in control thereof.

     SECTION 18. Renewal.
                 -------

          (a)    Notice of Renewal or Purchase. Except as otherwise specifically
                 -----------------------------                                  
provided in Section 18(d), not more than 720 nor less than 540 days prior to the
expiration of the Basic Term or the First Renewal Term, as the case may be, but
in no event before Lessee shall have received the Subsequent Appraisal (provided
Lessee ordered it as provided in Section 20(c), below) (the "Preliminary Notice
Expiration Date"), Lessee shall give Lessor notice (the "Preliminary Notice")
of Lessee's irrevocable intention either to (i) purchase pursuant to Section
19(a)(i), or renew the Lease pursuant to Section 18(b) in respect of, any
Selected Transponder(s); or (ii) purchase pursuant to Section 19(a)(i), or renew
the Lease pursuant to Section 18(b) in respect of, all but not less than all of
the Transponders.

          If, during the Basic Term, Lessee timely provides the Preliminary
Notice, then not later than 270 days prior to the expiration of the Basic Term,
Lessor shall provide Lessee with written notice specifying whether Lessee's
renewal right under Section 18(b) with respect to any such Transponder shall be
for (A) the Single Renewal Term or (B) two Renewal Terms (i.e., a First Renewal
Term and a Second Renewal Term) (the "Renewal Term Notice"), provided that if
such Renewal Term Notice is not timely given by Lessor, then such notice shall
be deemed to have been given by Lessor and to have specified two Renewal Terms.

          If Lessee timely provides the Preliminary Notice under clause (i) of
the first paragraph of Section 18(a), then Lessee shall also, concurrently
therewith, deliver to Lessor a certificate from the chief executive, chief
financial or chief operating officer of Lessee stating that:

                                      31
<PAGE>
 
               (1)    the Transponder as to which such Preliminary Notice has
     been given is the subject of a Use Agreement or Existing Lease which, by
     its terms, may be extended by the User or Sublessee beyond the Lease Term
     (the "Extension Right"); and

               (2)    such right of the User or Sublessee has either been
     exercised, or is presently in effect and has not been waived by such User
     or Sublessee; and

               (3)    the Extension Right was not given to such User or
     Sublessee for the primary purpose of enabling the Lessee to meet the
     conditions necessary to have the Transponder treated as a Selected
     Transponder.

          If Lessee gives the Preliminary Notice, then (except as provided in
Section 18(d)) not less than (180) days before the expiration of the Basic Term
or the First Renewal Term, as applicable (the "Final Notice Expiration Date"),
Lessee shall give Lessor notice of its irrevocable election (the "Final Notice")
of one of the following options: (i) to renew this Lease pursuant to Section
18(b) for the Transponder(s) identified in the Preliminary Notice (A) for a
Single Renewal Term, if applicable, or (B) for the First Renewal Term or Second
Renewal Term, as applicable, or (ii) to purchase the Transponder(s) identified
in the Preliminary Notice pursuant to Section 19(a)(i).

          If Lessee shall fail timely to deliver the Preliminary Notice, then,
except as provided in Section 18(d), Lessee shall be deemed not to have elected
to renew this Lease or purchase any Transponder, and promptly thereafter, but in
any case within 30 days after the Preliminary Notice Expiration Date, shall
provide Lessor with the names, last known business addresses and telephone
numbers of the Persons using any Transponder pursuant to a Use Agreement (not
including any Occasional Use Service Contract) or an Existing Lease. If Lessee
shall fail to deliver the Final Notice as required above after having delivered
the Preliminary Notice, Lessee shall be deemed to have elected to purchase the
Transponders identified in such Preliminary Notice pursuant to Section 19(a)(i).
The notice requirements of this Section 18(a) shall not apply to Lessee's right
to purchase any Transponders pursuant to Sections 19(a)(ii) through 19(a)(vi).

          (b)    Fair Market Value Renewal Option. If Lessee delivers the Final
                 --------------------------------                              
Notice set forth in Section 18(a), above, stating that it will renew the Lease
in respect of the Transponders identified in such Final Notice, and so long as
no Bankruptcy Default or Event of Default has occurred and is continuing at the
end of the Basic Term or, if applicable, the First Renewal Term, then this Lease
shall be renewed with respect to such Transponders at a Base Rent equal to the
Fair Market Rental Value of such Transponders (as determined pursuant to the
most recent Subsequent Appraisal) and payable in accordance with Section 18(c),
below. The Renewal Term shall be for the following period: (i) in the event
Lessor has specified a Single Renewal Term option in the Renewal Term Notice,
then the term shall begin immediately upon the expiration of the Basic Term and,
unless earlier terminated pursuant to the terms of this Agreement, shall end on
the earlier of the last day of the useful commercial life of the Satellite (as
determined pursuant to the most recent Subsequent Appraisal) or on the date the
Satellite is disposed of pursuant to Section 13 of the Purchase Agreement or
(ii) in the event Lessor has specified two Renewal Terms in the Renewal Term
Notice, then the term shall begin immediately upon expiration of the Basic Term
and, unless earlier terminated pursuant to the terms of this Agreement, shall
end on the day prior to the last day of the period of time which is equal to 75%
of the remaining useful commercial life of the Satellite (as determined pursuant
to the Subsequent Appraisal) measured from the commencement of such term (the
"First Renewal Term"). If Lessee renews the Lease for a First Renewal Term, and
provided no Bankruptcy Default or Event of Default has occurred and is
continuing at the end of the First Renewal Term, Lessee may renew the Lease
(pursuant to the procedure set forth in Section

                                      32
<PAGE>
 
18(a), above) for a second renewal term, on terms identical to the First Renewal
Term as set forth in the immediately preceding sentence, except only that such
second renewal term shall begin immediately upon the expiration of the First
Renewal Term and, unless earlier terminated pursuant to the terms of this
Agreement, shall end on the last day of the useful commercial life of the
Satellite (as determined pursuant to the most recent Subsequent Appraisal) or on
the date the Satellite is disposed of pursuant to Section 13 of the Purchase
Agreement (the "Second Renewal Term"). At the end of the Basic Term or First
Renewal Term, as applicable, if Lessee has timely elected to renew this Lease
with respect to any Transponder, then the terms and conditions of this Lease
with respect to such Transponder shall continue in full force and effect during
the following Renewal Term, except that (x) Lessee shall pay Lessor Base Rent
for such Transponder in the amount of the Fair Market Rental Value thereof as
determined by the most recent Subsequent Appraisal and (y) the Stipulated Loss
Values and Termination Values applicable during such Renewal Term shall
initially be the Fair Market Sales Value (determined pursuant to such Subsequent
Appraisal) of such Transponder as of the commencement of the Renewal Term and,
on each Casualty Payment Date during the Renewal Term, shall decline on a
straight line basis by an amount per Casualty Payment Date obtained by dividing
(A) the difference between the Fair Market Sales Value of such Transponder as of
the beginning of such Renewal Term and the estimated Fair Market Sales Value of
such Transponder as of the end of such Renewal Term by (B) the number of months
in such Renewal Term.
 
          (c)    Renewal Rents. At the end of the Basic Term or the First
                 -------------
Renewal Term, as the case may be, if Lessee shall have timely elected to renew
this Lease as aforesaid and if no Bankruptcy Default or Event of Default shall
then exist and be continuing, Lessee and Lessor shall execute a lease supplement
hereto in form and substance reasonably satisfactory to Lessor and Lessee to
evidence such renewal. Such lease supplement shall provide for the semi-annual
(or shorter period if necessary in case of the last Lease Period) payment of
Base Rent for the Renewal Term, with a final installment on the last day of any
such Renewal Term, payable in each case in arrears, in accordance with the
aforesaid determinations of Base Rent and shall provide for Stipulated Loss and
Termination Values for the Transponders covered thereby with respect to such
Renewal Term determined as aforesaid. The installments of Base Rent during the
Renewal Term shall be equal in amount (except for the last such installment
which shall be pro rated, if necessary, for a Lease Period which is shorter than
six months). All other terms of the Operative Documents and the Hughes
Agreements shall continue in effect during each such Renewal Term in accordance
with the provisions thereof and to the extent provided therein, except as
otherwise expressly provided in this Lease.
 
          (d)    Extended Notice. If with respect to any Transponder subject to
                 ---------------
an Existing Lease or Use Agreement (the "Subleased Transponder(s)"), Lessee has
not timely provided the Preliminary Notice and, if following the Preliminary
Notice Expiration Date but on or prior to the end of the Lease Term the
Sublessee or User under such Existing Lease or Use Agreement exercises its
renewal rights thereunder, if such renewal rights extend beyond the Lease Term,
then Lessee shall be entitled to give the Final Notice with respect to such
Subleased Transponder, such notice to be provided on or before the end of the
Lease Term; provided, however, that Lessee shall not be entitled to exercise the
            --------  -------
foregoing rights with respect to such Subleased Transponder if during the period
from the Preliminary Notice Expiration Date and prior to Lessee's delivery of
the Final Notice, Lessor has executed a valid and binding agreement (including a
binding commitment letter or letter of intent) for the purchase, lease or use of
such Subleased Transponder with a third party that is not an Affiliate and has
timely notified Lessee of such execution. During the period between the
Preliminary Notice Expiration Date and the end of the Lease Term, Lessor shall
promptly provide Lessee with written notice of the consummation of any such
agreement with respect to any Subleased Transponder as to which Lessee has not
timely provided the Preliminary Notice.

any Event of Default has occurred and is continuing, Lessee shall have the right

     Agreement shall result in (A) an increase in the present value of the
     Scheduled Rent with respect to the Transponders (up to and including the
     EBO Date) and the EBO Amount (discounted to the In-Service Date at the
     Discount Rate) as compared to the present value set forth in Item 8 to
     Schedule E, of more than 2% of the Lessor's Cost with respect to the

          (b)  Notice of Election; Manner of Purchase; Transfer After Purchase.
               --------------------------------------------------------------- 

               (i)  (1) In order to exercise its right to purchase the
     Transponders pursuant to Section 19(a)(ii), Lessee shall, at least ninety
     (90) (but not more than 360) days prior to the EBO Date, give irrevocable
     notice to Lessor in writing stating that Lessee will purchase such
     Transponders pursuant to Section 19(a)(ii). (2) In order to exercise its
     right to purchase all of the Transponders pursuant to Section 19(a)(iii),
     Lessee shall give tentative notice to Lessor in writing within 90 days
     after (A) Owner Participant shall have confirmed to Lessee pursuant to
     Section 5.02(i) of the Participation Agreement that it is a Competitor, or
     (B) Lessee shall have notified Owner Participant that Owner Participant has
     become a Competitor, and Owner Participant shall have become a Competitor,
     whichever of (A) or (B) shall first occur. (3) [Intentionally omitted]. (4)
     In order to exercise its right to purchase all of the Transponders pursuant
     to Section 19(a)(v), Lessee shall give tentative notice to Lessor in
     writing within forty-five (45) days after making the determination pursuant
     to Section 19(a)(v). (5) In order to exercise its right to purchase all of
     the Transponders pursuant to Section 19(a)(vi), Lessee shall give
     irrevocable notice to Lessor in writing on or before July 1, 1993.

               (ii) In the case of any tentative or irrevocable notice pursuant
     to Sections 19(b)(i)(2), 19(b)(i)(4) and 19(b)(i)(5), Lessee shall further
     specify that it desires to obtain an appraisal of the Fair Market Sales
     Value of the Transponder(s) as of the Rent Payment Date (which Rent Payment
     Date shall be the next succeeding Rent Payment Date no earlier than 30 days
     following the date of such tentative notice) or other permitted date
     specified in such notice, as applicable. Promptly after Lessee shall have
     given such notice, such Fair Market Sales Value shall be determined
     pursuant to the Appraisal Procedure (provided that the timetable for the
     Appraisal Procedure shall be appropriately accelerated to meet the
     deadlines set forth in the next sentence, so long as notwithstanding such
     acceleration, the appraiser shall have adequate time to make a considered
     determination). Lessee shall give irrevocable notice to Lessor not later
     than ten (10) Business Days after the completion of the Appraisal Procedure
     if it desires to consummate the purchase of the Transponder(s) pursuant to
     Sections 19(a)(iii) or 19(a)(v), but in no event later than fifteen (15)
     days prior to the Rent Payment Date or other permitted date specified in
     the tentative notice referred to in this Section 19(b)(ii), which Rent
     Payment Date shall be the next succeeding Rent Payment Date no earlier than
     30 days following the date of such tentative notice.

               (iii) Subject to Section 19(b)(iv), on the date of purchase,
     Lessee shall pay the purchase price for the applicable Transponder(s),
     together with (A) all amounts of Interim Rent and Base Rent with respect to
     such Transponders due and unpaid prior to the date of such purchase and
     (B)(i) at any time during the Basic Term, in the event that the date of
     purchase is a Rent Payment Date on which a Scheduled Rent payment
     designated as an "arrears rent" on Schedule A hereto, as adjusted pursuant
     to Section 12.05 or 12.06, subject to Sections 12.07 and 12.08, of the
     Participation Agreement, as applicable, is due, the sum of any Scheduled
     Rent with

                                      35
<PAGE>
 
     respect to such Transponders designated as an "arrears rent" on Schedule A,
     as adjusted pursuant to Section 12.05 or 12.06, subject to Sections 12.07
     and 12.08, of the Participation Agreement, as applicable, and due on such
     date of purchase and the Rent Differential Amount with respect to such
     date, if any, or (ii) at any time during a Renewal Term, any Base Rent due
     on such date and (C) any other Rent (including an amount equal to Variable
     Amount, if any) with respect to such Transponders due and unpaid as of the
     date of such purchase and, in the case of a purchase pursuant to Section
     19(a)(vi), any Rent Differential Amount due and unpaid as of the date of
     such purchase. Upon receipt of the payments set forth in the preceding
     sentence, Lessor shall transfer all right, title and interest of Lessor in
     and to the applicable Transponders, as is and where is, to Lessee, free and
     clear of Lessor Liens and Owner Participant Liens, but otherwise without
     warranty, and Lessor shall execute and deliver to Lessee, at Lessee's
     reasonable expense, a bill of sale or assignment and such other
     instruments, documents and opinions as Lessee may reasonably request to
     evidence the valid consummation of such transfer and shall take such
     actions under Section 10 of the Indenture as Lessee may reasonably request.
 
               (iv) Subject to Section 19(a), if Lessee shall provide the
     irrevocable notice pursuant to Section 19(b)(i)(1) to purchase all (but not
     less than all) of the Transponders on the EBO Date, then Lessee may, at its
     option, pay the EBO Amount therefor on a date not earlier than the same
     calendar day in the fourth month prior to the EBO Date (e.g., if the EBO
                                                             ----
     Date is July 2, 1998, not earlier than March 2, 1998), but in any event
     such payment must occur within the same taxable year of the Owner
     Participant as the EBO Date shall occur (the "EBO Prepayment"), and shall
     pay all other amounts pursuant to Section 19(b)(iii) due and owing as of
     the EBO Date on the EBO Date, and, upon receipt of all such amounts, Lessor
     shall on the EBO Date comply with the last sentence of Section 19(b)(iii).
     If Lessee shall make the EBO Prepayment pursuant to the immediately
     preceding sentence, then (i) from and after the making of the EBO
     Prepayment, the Stipulated Loss Value for each Transponder for all purposes
     in this Lease shall be reduced by an amount equal to the prepaid EBO Amount
     therefor, except that Stipulated Loss Value, as used in Section 16 hereof
     shall not be so reduced, except as provided therein, (ii) upon request of
     Lessee, if the Lien of the Indenture shall have been fully discharged,
     Lessor shall grant to Lessee a security interest in the Transponders,
     securing Lessor's obligation to comply with the last sentence of Section
     19(b)(iii), subject to receipt of the payment specified in Section
     19(b)(iii) on the EBO Date, subject to and as provided in Section
     19(b)(iii), and Lessee shall pay all reasonable expenses in connection with
     the granting of such security interest as Supplemental Rent on an After-Tax
     Basis.
 
          (c)  Assumption of Notes. Notwithstanding the provisions of Sections
               -------------------
19(a) and (b) and subject to compliance with Section 2.13 of the Indenture, in
connection with a purchase by Lessee of the Transponders pursuant to any of
Sections 19(a)(ii) through 19(a)(vi), as the case may be, at Lessee's option,
Lessee may assume the Notes (or the portion thereof associated with such
purchased Transponder, as applicable), pursuant to Sections 5.05 and 11.04 of
the Participation Agreement and the obligation of Lessee to pay the purchase
price pursuant to the applicable clause of Section 19(a) shall be satisfied by
such assumption of the Notes to the extent of the principal amount of the Notes
so assumed (after, in the event that the date of purchase is a Rent Payment Date
on which a Scheduled Rent payment designated as an "arrears rent" on Schedule A
hereto, as adjusted pursuant to Section 12.05 or 12.06, subject to Sections
12.07 and 12.08, of the Participation Agreement, as applicable, is due, payment
of the sum of any Scheduled Rent designated as an "arrears rent" on Schedule A,
as adjusted pursuant to Section 12.06 of the Participation Agreement, on the
Rent Payment Date on which such purchase is consummated with respect to the
applicable Transponder(s) and the Rent Differential Amount, if any). Once Lessee
has elected to exercise its option to assume the Notes by giving notice of such
election in
 
                                      36
<PAGE>
 
its notice pursuant to Section 19(b) hereof, such Notes shall be mandatorily
assumed by Lessee pursuant to the Indenture.

          (d)    No Duplication of Rent Differential Amount. In the event that a
                 ------------------------------------------                     
portion of the Scheduled Rent due on any date of purchase is designated as an
"arrears rent" on Schedule A and there is also a payment of Scheduled Rent due
on such date of purchase that is not so designated, a portion of the Rent
Differential Amount with respect to such date of purchase shall be added to the
Scheduled Rent designated as an "arrears rent" due on such date and the
remainder of such Rent Differential Amount shall be taken into account in the
computation of the EBO Amount or the computation of Termination Value, as
appropriate. It is intended that the entire amount of the Rent Differential
Amount due on such date of purchase shall be allocated between the Scheduled
Rent designated as an "arrears rent" due on such date and the computation of the
EBO Amount or the Termination Value, as appropriate and without duplication, in
such manner as will preserve the Owner Participant's Net Economic Return and
comply with the minimum payment requirement (it being understood that the entire
amount of such Rent Differential Amount shall be taken into consideration in
making such allocation).

     SECTION 20. Further Assurances; Default Notice.
                 ----------------------------------

          (a)    Further Assurances. Lessee, at its reasonable expense, shall
                 ------------------                                          
promptly and duly execute and deliver to Lessor, Owner Participant and Indenture
Trustee such documents and assurances and take such further action as Lessor
(and Indenture Trustee) may from time to time reasonably request in order to
carry out more effectively the intent and purpose of this Lease, the other
Operative Documents and the Hughes Agreements and to establish and protect the
rights and remedies created or intended to be created in favor of Lessor
hereunder and thereunder, to establish, perfect (to the extent practicable, in
the case of the Transponders), and maintain Lessor's right, title and interest
in and to the Transponders and the Indenture Estate and, for the benefit of
Indenture Trustee, the lien and security interest in the Indenture Estate
provided for in the Indenture, subject to no Lien other than Permitted Liens,
including, without limitation, if requested by Lessor, Owner Participant or
Indenture Trustee, at the expense of Lessee, the recording or filing of
appropriate memoranda hereof, or of such financing statements or other documents
with respect hereto as any of Lessor, Owner Participant or Indenture Trustee may
from time to time reasonably request, and Lessor agrees promptly to execute and
deliver such of the foregoing financing statements or other documents as may
require execution by Lessor and to the extent permitted by Applicable Laws,
Lessee hereby authorizes any such financing statements to be filed without the
necessity of signature by Lessee; provided, however, no counterparts hereof
                                  --------  -------                        
shall be filed, unless Lessor or Indenture Trustee shall determine that it is
advisable, in the reasonable opinion of the counsel of Lessor or Indenture
Trustee, as the case may be, to file such counterpart in order to protect its
interest under this Lease; then, upon 30 days prior notice and delivery to
Lessee of such opinion of counsel of Lessor or Indenture Trustee, as the case
may be, Lessor or Indenture Trustee, as the case may be, may file such
counterpart.

          (b)    Notice of Default. Promptly after obtaining Actual Knowledge of
                 -----------------                                              
the occurrence or existence of any Default or Event of Default, Lessee shall so
notify Lessor (and Indenture Trustee) and set forth in reasonable detail the
circumstances surrounding such Default or Event of Default and shall specify
what actions Lessee has taken or intends to take to cure such Default or Event
of Default.

          (c)    Subsequent Appraisal. No earlier than 760 days and no later
                 --------------------                                       
than 720 days prior to the end of the Basic Term or the First Renewal Term, as
applicable, Lessee shall have the option to initiate the Appraisal Procedure,
and at Lessee's cost and expense, to cause an appraisal of the Transponders to
determine, as appropriate, the remaining useful commercial life, residual value
and the Fair Market Sales Value of the Transponders as of the end of the Basic
Term and the Fair Market Rental Value of the Transponders as of the end of the
Basic Term or First Renewal Term, as applicable. In addition, no earlier than
180 days nor later than 120 days prior to the end of the First Renewal Term,
Lessee shall have the option to initiate the Appraisal Procedure, and at
Lessee's cost and expense, to cause an appraisal of the Transponders to be
performed to determine the Fair Market Rental Value and the Fair Market Sales
Value of the Transponders as of the end of such Renewal Term. Any appraisal
pursuant to this Section 20(c) shall be deemed a "Subsequent Appraisal."

     SECTION 21. Indenture Estate as Security for Lessor's Obligations to
                 ---------------------------------------------------------
Indenture Trustee.
- -----------------

          (a)    In order to secure the indebtedness evidenced by the Notes and
all obligations secured by the Indenture, Lessor provides in the Indenture,
among other things, for the assignment (to the extent provided therein) by
Lessor to Indenture Trustee of all of Lessor's right, title and interest to this
Lease and for the creation of a Lien and security interest in favor of Indenture
Trustee for the benefit of the Noteholders in and to the Indenture Estate as
described in the granting clauses of the Indenture. Lessee hereby (a) consents
to such assignment pursuant to the terms of the Indenture, and (b) agrees to pay
directly to Indenture Trustee for so long as the Lien of the Indenture shall
remain in effect and thereafter to Lessor, all amounts (other than Excepted
Payments) due and to become due to or for the account of Lessor and payable by
Lessee hereunder or under any other Operative Document or Hughes Agreement to
which Lessee in any capacity is a party which have been assigned or required to
be assigned to Indenture Trustee pursuant to the Indenture or this Agreement.
Lessee acknowledges that, so long as any Notes are outstanding, all rights of
Lessor under this Lease shall be exercised only by the Indenture Trustee, as
assignee of Lessor's rights under this Lease pursuant to the Indenture, subject,
however, to Sections 9.2, 13.1 and 16.4 of the Indenture and subject to Lessor's
rights in respect of Excepted Payments.

          (b)    Notwithstanding anything to the contrary hereinabove, Indenture
Trustee shall not have any greater rights under the Hughes Agreements than
Lessor shall have pursuant to Section 5(b)(ii) and (iii) of this Agreement or
than the Lessor otherwise has under this Lease.

     SECTION 22. Counterparts; Uniform Commercial Code.
                 -------------------------------------

          This Lease and each Lease Supplement may be executed by the parties
hereto in separate counterparts, each of which when so executed and delivered
shall be an original, but all such counterparts shall together constitute but
one and the same instrument. To the extent, if any, that this Lease constitutes
chattel paper (as such term is defined in the Uniform Commercial Code as in
effect in any applicable jurisdiction), no security interest in this Lease may
be created through the transfer or possession of any counterpart hereof other
than the original executed counterpart which shall be identified as the
counterpart containing the receipt therefor executed by Indenture Trustee on the
signature page thereof.

                 -------------

          (a)    Severability. Any provision of this Lease which is prohibited
                 ------------

ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof or of any provision in any other
Operative Document or Hughes Agreement, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction. The provisions of this
Lease shall remain valid and enforceable notwithstanding the invalidity,
unenforceability, impossibility or illegality of performance of any other
Operative Document.

          (b)    Amendment. Neither this Lease nor any of the terms hereof may
                 ---------                                                  
be terminated, amended, supplemented, waived or modified orally, but only by an
instrument in writing signed by the party against which the enforcement of the
termination, amendment, supplement, waiver or modification is sought and, unless
and until Lessee and Lessor shall have received written notice from Indenture
Trustee that the Lien of the Indenture on the Indenture Estate has been released
by Indenture Trustee, no amendment, supplement or waiver by Lessor or Lessee
shall be effective without the written consent of Indenture Trustee, except as
expressly provided in the Indenture.

SCHEDULE OF AGREEMENTS OMITTED ON THE BASIS OF BEING SUBSTANTIALLY IDENTICAL TO
   THE AGREEMENTS FILED AS EXHIBITS 10.5.1, 10.5.2, 10.5.3, 10.6.1 AND 10.6.2
        (FILED PURSUANT TO INSTRUCTION 2 OF ITEM 601 OF REGULATION S-K)


10.5.1  PARTICIPATION AGREEMENTS
        ------------------------

     The Participation Agreement, dated as of August 21, 1992, among Hughes
Communications Galaxy, Inc. ("HCG"), Orion One, Inc., State Street Bank and
Trust Company of Connecticut, National Association ("State Street"), Hughes
Communications, Inc. ("HCI"), Wilmington Trust Company and BT Securities
Corporation, filed with this Registration Statement as Exhibit 10.5.1, is one in
a series of ten Participation Agreements which relate to sale-leaseback
transactions involving the transponders aboard the Galaxy VII satellite.  Each
such sale-leaseback transaction is documented by a separate set of contracts,
including separate Participation Agreements, each of which is substantially
identical to the others.  The only material difference in such agreements is the
name of the trust that is a party to such agreement.  Accordingly, as the name
of the trust in the Participation Agreement filed as Exhibit 10.5.1 is "Orion
One," the names of the trusts that are parties to the remaining nine
Participation Agreements are "Orion Two," "Orion Three," "Orion Four" and so on,
respectively.

     The schedules and exhibits attached to the Participation Agreements are
different with respect to each Trust.  However, because such schedules and
exhibits are voluminous, they have not been filed.

10.5.2  FIRST AMENDMENTS TO PARTICIPATION AGREEMENT
        -------------------------------------------

     The First Amendment to Participation Agreement, dated as of December 24,
1992, among HCG, Orion One, Inc., State Street, HCI, Wilmington Trust Company
and BT Securities Corporation, filed with this Registration Statement as Exhibit
10.5.2, amends the Participation Agreement filed as Exhibit 10.5.1.  The
remaining nine Participation Agreements are likewise amended by substantially
identical contracts.  One material difference in such agreements is the name of
the trust that is a party to such agreement.  Accordingly, as the name of the
trust in the First Amendment to Participation Agreement filed as Exhibit 10.5.2
is "Orion One," the names of the trusts that are parties to the remaining nine
First Amendments to Participation Agreement are "Orion Two," "Orion Three,"
"Orion Four" and so on, respectively.  In addition, in the first and fourth
"whereas" clauses and in section 1y of the First Amendment to Participation
Agreement filed as Exhibit 10.5.2, the references to "Trust 1" are replaced by
"Trust 2," "Trust 3," "Trust 4," and so on, respectively, in the First
Amendments to Participation Agreement relating to the remaining nine trusts.

  Further, in the Trust 5 First Amendment to Participation Agreement to which
Orion Five is a party, on page 13, the following paragraph is added to Section
3:

     "Transponder No. 7.  The parties agree that Transponder No. 7 shall be sold
      ------------------
     to HCG as of the In-Service Date for a price equal to Special Termination
     Value therefor pursuant to a bill of sale and related documents as the
     parties shall reasonably determine."
     

  Finally, in the First Amendment to Participation Agreement to which Orion
Seven is a party, on page 13, the following paragraph is added to Section 3:

     "Satisfaction of Conditions to Transfer.  If the Owner Participant is Orion
      --------------------------------------
     Two, Inc., then the parties hereto have been informed that Bankers Trust
     Company intends to sell the shares of Common Stock in the Owner Participant
     to State Street Bank and Trust Company ("State Street").  Each party has
     received on the date hereof a copy of the form of guarantee (labeled
     "Execution Copy (Form Submitted at Debt Closing)") to be 
<PAGE>
 
     delivered by State Street pursuant to Section 13.02(a)(i) of the
     Participation Agreement and a form of the legal opinion of counsel for
     State Street (labeled "Execution Copy (Form Submitted at Debt Closing)") to
     be delivered pursuant to Section 13.02(a)(xi) of the Participation
     Agreement, each in connection with such sale. Each party agrees that, if
     such guarantee and such legal opinion are delivered at the consummation of
     such sale in the form received on the date hereof, then such guarantee and
     such legal opinion shall be deemed to have satisfied the relevant
     requirements of Section 13.02(a) of the Participation Agreement and Bankers
     Trust Company, as Parent, shall be released from all liabilities and
     obligations to the extent provided in Section 13.02(b) of the Participation
     Agreement."

10.5.3  SECOND AMENDMENTS TO PARTICIPATION AGREEMENT
        --------------------------------------------

  The Second Amendment to Participation Agreement, dated as of June 18, 1993,
among HCG, Orion One, Inc., State Street, CIBC Inc., Internationale Nederlanden
Lease Structured Company and BT Securities Corporation further amends the
Participation Agreement filed as Exhibit 10.5.1 and is attached to this
Registration Statement as Exhibit 10.5.3.  The remaining nine Participation
Agreements are likewise further amended by substantially identical contracts.
As with the original Participation Agreements, the only material difference
among such agreements is the name of the trust that is a party to such
agreement.  Accordingly, as the name of the trust in the Second Amendment to
Participation Agreement filed as Exhibit 10.5.3 is "Orion One," the names of the
trusts that are parties to the remaining nine Second Amendments to Participation
Agreement are "Orion Two," "Orion Three," "Orion Four" and so on, respectively.

10.6.1  LEASE AGREEMENTS
        ----------------

  The Lease Agreement, dated as of December 31, 1992, by and between HCG and
State Street, attached to this Registration Statement as Exhibit 10.6.1 is one
in a series of ten Lease Agreements which relate to the same sale-leaseback
transactions to which the Participation Agreements relate.  The only material
difference among the ten Lease Agreements is the trust referenced in the
preamble of each such agreement.  Accordingly, as "Trust 1" appears in the
preamble of the Lease Agreement filed as Exhibit 10.6.1, "Trust 2," "Trust 3,"
"Trust 4" and so on, respectively, appear in the preambles of the Lease
Agreement related to the remaining nine trusts.

  The schedules and exhibits attached to the Lease Agreements are different with
respect to each Trust.  However, because such schedules and exhibits are
voluminous, they have not been filed.

10.6.2  FIRST AMENDMENTS TO LEASE AGREEMENT
        -----------------------------------

     The First Amendment to Lease Agreement, dated as of June 18, 1993, by and
between HCG and State Street, filed with this Registration Statement as Exhibit
10.6.2, amends the Lease Agreement filed as Exhibit 10.6.1.  The Lease
Agreements relating to Trusts 2 through 10 are likewise amended by substantially
identical contracts.  As with the original Lease Agreements, the only material
difference among such agreements is the trust referenced in each such agreement.
Accordingly, as "Trust 1" appears in "whereas" clauses 1 and 4 of the First
Amendment to Lease Agreement filed as Exhibit 10.6.2, "Trust 2," "Trust 3,"
"Trust 4" and so on, respectively, appear in whereas clauses 1 and 4 of the
Lease Agreement related to the remaining nine trusts.

          report the probable cause and necessity for withholding such property
          from use.

     8.5  Upon termination or completion of this Contract, and upon request by
          HCG, the Contractor shall perform a physical inventory, adequate for
          accountability and disposition purposes, of all HCG's Property
          applicable to such terminated or completed agreement and shall cause
          its subcontractors and suppliers at every tier to do likewise.

          provided hereunder shall take place in accordance with the terms of
          Article 10, entitled "Access to Work in Process," herein.

     9.2  Preliminary Acceptance of the Spacecraft shall occur when all in-plant
          tests required to be performed by Contractor for the Hardware have
          been completed and the Contractor has demonstrated at the pre-ship
          review that the Hardware meets the requirements of Exhibit B, at which

          within five (5) business days subject to completion of Launch Site
          tests specified in Exhibit D, Galaxy IX Spacecraft Test Plan.  If the
          Hardware is unacceptable, Contractor shall promptly and at its
          expense, rectify the unsatisfactory Hardware and resubmit the Hardware
          for acceptance by HCG as provided above.  In either case, the Hardware
          shall be deemed accepted upon failure of HCG to notify Contractor
          within the above five (5) business days that it is accepted or
          rejected.

     9.3  Final Acceptance of the Spacecraft shall occur upon i) the completion

          Final Acceptance shall occur at the end of the ********** warranty
          period as set forth in Article 16 herein, entitled "Spacecraft
          Warranty", or such other event mutually agreed upon between the

ARTICLE 10. ACCESS TO WORK IN PROCESS
            -------------------------

     10.1  Contractor shall afford HCG access to work in progress being
           performed at Contractor's plants and at the Launch Site pursuant to
           this Contract, including technical data, documentation, and hardware,

ARTICLE 11. TERMINATION FOR DEFAULT
            -----------------------

     11.1  Subject to the provisions of Article 5, entitled "Price" and Article
           12, entitled "Excusable Delays," HCG may issue a written Notice of
           Default to Contractor if: i) Contractor fails ********** 
           ********** as confirmed by Seller's responsible Business Unit, and
           HCG Management Review; or ii) if Contractor fails to make delivery of
           the Goods, or to perform the Services, within the time specified or
           any extension thereof. HCG may terminate the whole or any part of
           this Contract if Contractor does not initiate action to cure such
           failure within a period of ******* days (or such longer time as HCG
           may authorize in writing) after receipt of notice from HCG specifying
           such failure. HCG agrees that it will not terminate this Contract for
           default so long as corrective action is being diligently pursued by
           Contractor so as to provide reasonable assurance that the work
           covered by this Contract shall be fully completed in sufficient time
           to allow HCG to meet its launch date as specified in Article 7,
           "Spacecraft Launch Date," of this Contract.

     11.2  If HCG terminates this Contract in whole or in part, as provided in
           Paragraph 11.1 herein,  HCG, at it's sole option, shall either: i)
           take title to all deliverable hardware, all hardware in process which
           ultimately would have been deliverable by Contractor and all drawings
           and data produced by Contractor, the cost of which has been charged
           or becomes chargeable to any work terminated plus all reasonable
           reprocurement costs up to a maximum amount of *****************
           ********************** or ii) receive a refund of ************
           *************************************** and Contractor shall retain
           title and possession to all terminated Hardware which ultimately
           would have been deliverable by Contractor.  Contractor shall continue
           the performance of this Contract to the extent not terminated under
           the provisions of this Article.

     11.3  If, after termination of this Contract under the provisions of this
           Article, it is determined for any reason that Contractor was not in
           default under the provisions of this Article, or that the default was
           excusable under the provision of Article 12 entitled "Excusable
           Delays," the rights and

     11.4  Except as otherwise provided in the Contract, the rights and
           remedies provided in this Article shall be in lieu of any other
           rights and remedies provided by law or in equity in the event
           Contractor fails to meet its obligations under this Contract.

ARTICLE 12. EXCUSABLE DELAYS
            ----------------

     12.1  If either Party or a subcontractor of either Party is delayed by act
           of God, or of the public enemy, fire, flood, earthquake, epidemic,
           quarantine restriction, strike, walkout, freight embargo, or any
           other event which is beyond their control or does not arise from the
           acts or omissions of either Party or its respective subcontractors,
           said delay shall constitute an excusable delay.  In the event of an
           excusable delay, there shall be an equitable adjustment to the time
           of delivery and/or performance stated in this Contract.  The affected
           Party shall give notice to the other Party within 10 working days
           that an excusable delay condition exists after learning of such
           delay.  Such notification shall include the cause of the excusable
           delay, the expected length of the excusable delay, and alternate
           plans to mitigate the effect of the excusable delay.

     12.2  If the affected Party, as defined in Paragraph 12.1 above, requests
           or experiences, on a cumulative basis, excusable delay(s) greater
           than **************** days, the Parties shall enter into good faith
           negotiations to develop a mutual course of action and/or an equitable
           adjustment to the affected terms of this Agreement.

     12.3  Notwithstanding the foregoing, if the Launch Date defined in
           Paragraph 7.1 herein is delayed due to an excusable delay affecting
           either Party or a subcontractor thereof at any point in time after
           the shipment of the Spacecraft to the Launch Site has occurred, HCG
           shall reimburse Contractor for all reasonable expenses. Expenses
           included in any equitable adjustment shall include but not be limited
           to; support personnel standby; extra travel expenses; transport
           termination or rescheduling fees; and installation/de-installation of
           communication links to the Launch Site and a profit rate of
           ****************** or such other profit rate designated in writing by
           the Chief Financial Officer of the Hughes Space and
           Telecommunications Company (or then existing equivalent) for the
           applicable excusable delay expenses.

ARTICLE 14. TERMINATION FOR CONVENIENCE
            ---------------------------

     14.1 HCG may terminate all or any portion of the work to be performed
          pursuant to this Contract upon five (5) days written notice to
          Contractor.  HCG shall pay Contractor, in the event of such
          termination, termination liability equaling all costs expended by
          Contractor for all work done up to the date of termination,
          settlements with subcontractors for work performed prior to
          termination, and Contractor's costs related to termination which would
          not otherwise have been incurred plus a **** profit or such other
          profit rate designated in writing by the Chief Financial Officer of
          the Hughes Space and Telecommunications Company (or then existing
          equivalent) for the applicable termination costs and charges less
          amounts previously paid by HCG to Contractor pursuant to the Payment
          Article.  In no event shall the termination liability exceed the
          Contract price defined in Article 4 herein.

     14.2 In the event of termination by HCG hereunder, all tangible work in
          process inventories generated under this Contract, with respect to the
          terminated work, shall become the property of HCG.  HCG shall direct
          disposition of such property within sixty (60) days from date of
          termination.  Final acceptance and transfer of title for all tangible
          work in process inventories to be delivered to the Buyer in the event
          of termination shall be the subject of separate negotiations between
          Buyer and Contractor.  The expense of disposition shall be borne by
          HCG.

     14.3 In the event of partial termination, the Parties shall, by
          negotiation, equitably re-price the unterminated goods and services,
          and the Contract price shall be adjusted accordingly.

     14.4 In the event that the Contractor identifies an alternate use (i.e.
          sale to third Parties and/or internal utilization) for any Hardware
          affected by a termination under this Article 14, the Contractor shall
          submit a proposal to HCG, which, at a minimum, defines i) the
          applicable Hardware; ii) the intended use of the Hardware; iii) the
          original acquisition cost/value of the applicable Hardware, as
          available; and iv) the sale/transfer payment(s) to be received by HCG.
          HCG, at its sole option, may accept or reject the proposal submitted
          by Contractor.  In the event that HCG accepts the

<PAGE>
 
          proposal submitted by Contractor, payment by Contractor to HCG of the
          agreed upon payment value shall occur within thirty (30) days of the
          sale/transfer of the applicable Hardware, or such other payment period
          as mutually accepted between the Parties. If the Contractors proposal
          is rejected by HCG, HCG shall retain Title to the applicable Hardware.

ARTICLE 15. TITLE - RISK OF LOSS
            --------------------

     15.1 Title and risk of loss or damage in respect of all items to be
          delivered under this Contract shall pass from Contractor to HCG as
          follows:

          1.  Risk of loss of the Spacecraft and title shall pass from
              Contractor to HCG upon; i) the completion of In-orbit Testing by
              HCG; or  ii) forty-five (45) days after Intentional Ignition (as
              defined in Paragraph 16.3 herein); or iii) upon the Partial
              Failure, Total Failure or Total Constructive Failure of the
              Spacecraft, as defined in the applicable HCG Launch Insurance
              Contract, whichever occurs first.

          2.  In respect to a Spacecraft which HCG directs Contractor to store,
              title and risk of loss shall remain with the Contractor until
              Final Acceptance as specified in Article 9.4 herein.

          3.  Notwithstanding Paragraph 15.1.2 above, upon removal of the
              Spacecraft from storage, the Contractor shall not assume risk of
              loss relative to a Battery which HCG directs Contractor to replace
              after the five-year storage period which disqualifies the battery
              for a 12-year mission.  In that event, Article 29 herein entitled
              "Effects of Storage on Batteries," shall apply.

     15.2 In the event of damage to or destruction of Hardware when Contractor
          shall have risk of loss, Contractor shall repair or replace (at
          Contractor's option) said Hardware.  The Buyer shall participate in
          the decision to repair or replace said Hardware.

ARTICLE 16. SPACECRAFT WARRANTY
            -------------------

     16.1 Contractor warrants that a Spacecraft, upon successful completion of
          Spacecraft in-plant Tests pursuant to Article 9 herein, shall be free
          from any defects in material or workmanship and shall conform to the
          applicable specifications and drawings, as evidenced by acceptance
          criteria, as defined in Exhibit D.

     16.2 HCG shall have the right at any time during the period of this
          warranty to reject any goods not conforming to this warranty and
          require that Contractor, at its expense, correct or replace (at
          Contractor's option) such goods with conforming goods. If Contractor
          fails to correct or replace such defective goods and fails to initiate
          reasonable efforts to correct or replace such defective goods within a
          reasonable period after notification and authorization from HCG, HCG
          may then, by contract or otherwise, correct or replace such defective
          goods and equitably adjust the price.

     16.3 This warranty shall start from the date of Preliminary Acceptance of a

ARTICLE 17. INDEMNIFICATION
            ---------------

     17.1  Each Party shall indemnify and hold the other and/or all its
           officers, agents, servants, subsidiaries, and employees, or any of
           them, harmless from any liability or expense in connection herewith
           on account of damage to property (excepting Spacecraft in flight) and
           injuries, including death, to all persons including but not limited
           to employees of the Parties, and their subcontractors, and of all
           other persons performing any part of the work hereunder, arising from
           any occurrence caused by an negligent act or omission of the
           indemnifying Party or its subcontractors, or any of them in
           connection with the work to be performed by such Party under this
           Contract.  The indemnifying Party shall have the right, but not the
           obligation, to participate in any legal or other proceedings
           concerning claims for which it is indemnifying under this Article 17
           and to direct the defense of such claims.  However, with respect to
           such legal or other proceedings, the indemnifying Party shall pay all
           expenses (including attorneys fees incurred by the indemnified Party
           in connection with such legal or other proceedings) and satisfy all
           judgments, costs or other awards which may be incurred by or rendered
           against the indemnified Party.  The indemnifying Party shall not
           settle any such claim, legal or other proceeding without first giving
           thirty (30) days prior written notice of the Terms and Conditions of
           such settlement and obtaining the consent of the indemnified Party,
           which consent shall not be unreasonably withheld or delayed.

     17.2  Notwithstanding the foregoing, neither the Contractor nor its
           subcontractors shall have any liability in contract or in tort, for
           damages to or caused by the Spacecraft after Intentional Ignition (as
           defined in Paragraph 16.3), and Buyer shall obtain waivers of
           subrogation rights from Buyer's insurers against Contractor, and
           affiliates and subcontractors of Contractor.

     17.3  In no event shall the Contractor or Buyer be liable for any
           incidental, special, contingent or consequential damages (including,
           but not limited to lost profits).

ARTICLE 18. SPACECRAFT NOT LAUNCHED WITHIN SIX MONTHS AFTER ACCEPTANCE
            ----------------------------------------------------------

     18.1  If the Spacecraft is not launched within six (6) months after its
           Preliminary Acceptance per Article 9, entitled "Inspection and
           Acceptance," and is subsequently ordered to be launched within one
           (1) year following its Preliminary Acceptance, it is agreed that such
           Spacecraft shall be returned at Contractor's option at Contractor's
           expense, to Contractor's facility for inspection and refurbishment.
           Any inspection and refurbishment undertaken by Contractor to meet the
           requirements of Article 16 entitled, "Spacecraft Warranty," shall be
           at Contractor's expense, including Spacecraft transit insurance.

     18.2  If the Spacecraft is not launched within six (6) months after its
           Preliminary Acceptance and is subsequently ordered to be launched
           later than one (1) year following its Preliminary Acceptance, it is
           agreed that such Spacecraft shall be returned, at HCG's expense, to
           Contractor's facility for inspection and refurbishment.  An equitable
           adjustment to Contract price for such inspection and refurbishment,
           to include a ****** profit rate (or such other profit rate designated
           in writing by the Chief Financial Officer of the Hughes Space and
           Telecommunications Company (or then existing equivalent) for the
           applicable expenses) shall be negotiated by the Parties unless the
           fact that the launch is scheduled for later than one (1) year is due
           to Contractor's negligent acts or omissions.

     18.3  If the Spacecraft is returned to Contractor's facility for inspection
           and refurbishment per the terms of Paragraph 18.2 above, all charges
           to return such Spacecraft to the Launch Site shall be borne by HCG.

     18.4  If the Spacecraft has not been launched within five (5) years after
           its preliminary Acceptance, neither Party shall be further obligated
           to the other with respect to such Spacecraft.  Disposition of such
           Spacecraft shall be at the option of HCG with costs of such
           disposition to be borne by HCG.

ARTICLE 19. PATENT/COPYRIGHT INDEMNITY
            --------------------------

     19.1  Contractor shall indemnify and hold HCG harmless against any
           liability or expense as a result of claims, actions, or proceedings
           against HCG alleging the infringement of any United States Letters
           Patent, or copyright of any data, or article fabricated by Contractor
           and delivered to HCG pursuant to this Contract as set forth below.

     19.2  Contractor agrees to defend at its own expense any request for
           royalty payments or any claim for equitable relief or damages against
           HCG, its officers, employees, agents, or subsidiaries based on an
           allegation that the manufacture of any item under this Contract or
           the use, lease, or sale thereof infringes any United States Letters
           Patent, and to pay any royalties and other costs related to the
           settlement of such request and to pay the costs and damages,
           including reasonable attorney's fees finally awarded as the result of
           any suit based on such claim, provided that Contractor is given
           prompt written notice of such request or claim by HCG and given
           authority and such assistance and information as is available to HCG
           for resisting such request or for the defense of such claim.  Any
           such assistance or information which is furnished by HCG at the
           written request of Contractor is to be at Contractor's expense.

     19.3  In the event that, as a result of any such suit: a) prior to
           delivery, the manufacture of any item is enjoined; or b) after
           delivery, the use, lease or sale thereof is enjoined, Contractor
           agrees to utilize its best effort to either: (1) negotiate a license
           or other agreement with plaintiff so that such item is no longer
           infringing; or (2) modify such item suitably or substitute a suitable
           item therefore, which modified or substituted  item is not subject to
           such injunction, and to extend the provisions of this
           Article thereto.  In the event that neither of the foregoing
           alternatives is suitably accomplished by Contractor, Contractor shall
           be liable to HCG for HCG's additional costs and damages arising as a
           result of such injunction; provided however, that in no event shall
           Contractor's entire liability under this Article exceed

ARTICLE 29. EFFECTS OF STORAGE ON BATTERIES
            -------------------------------

     For Spacecraft batteries to provide the required minimum twelve (12) years
     of in-orbit services per Exhibit B, Galaxy IX Spacecraft Specification, it
     is understood that launch must occur within five (5) years from the date of
     activation of the first battery cell. In the event Buyer directs Contractor
     to store any deliverable Spacecraft and the period of such storage causes a
     launch later than five (5) years from the date of activation of that
     Spacecraft's first battery cell and HCG directs Contractor to install
     replacement batteries to meet twelve (12) year in-orbit service
     requirement, then HCG shall pay Contractor its costs plus a **** profit
     rate or such other profit rate designated in writing by the Chief Financial
     Officer of the Hughes Space and Telecommunications Company (or then
     existing equivalent) for the applicable expenses for replacing batteries
     per Buyer's direction.

ARTICLE 30. INTER-PARTY WAIVER OF LIABILITY
            -------------------------------

     30.1 Prior to the time HCG and the Contractor enter the premises at the
          Launch Site, they each agree that they will not make a claim against
          each other for damage to, loss of, or loss of use of their property or
          the property of others in their possession, caused by the fault of
          negligence of the other Party to this Contract, or otherwise caused by
          any defect in any product manufactured or sold by the other Party to
          this Contract.  Such claims are waived and each Party will bear its
          own losses.  HCG will include a comparable clause in each of its
          contracts with vendors, subcontractors or customers for services or
          benefits expected as a result of the launch or orbiting of Galaxy
          Follow-on satellites.  Such comparable clause shall include a
          requirement to flow the clause down to lower-tier contractors.
 
     30.2 Notwithstanding any other provisions of this Contract, prior to the
          time any Party, associated with the Galaxy IX launch activities at the
          Launch Site, shall enter the premises at the Launch Site, such Parties
          shall be required to sign an Inter-Party Waiver of Liability
          consistent with that between HCG and the Contractor as incorporated
          herein under Paragraph 30.1 of this provision or other similar
          agreement as may be required by the launch agency.  Each Party shall
          have the responsibility to assure that all the Parties associated with
          the launch of Galaxy IX Spacecraft (for which they have control or
          privity of Contract with hereunder) have executed said Inter-Party
          Waiver of Liability.

ARTICLE 31. SPACECRAFT STORAGE
            ------------------

     31.1 Buyer may, at its option, order Contractor to store, in accordance
          with the provisions of Exhibit B Galaxy IX Spacecraft Specification,
          the deliverable Spacecraft (including separate storage of Batteries,
          if needed) for a period of up to 1 year from the date of their
          delivery to Buyer.  HCG shall provide written notice to the Contractor
          not later than six (6) months prior to the scheduled delivery of said
          Spacecraft.  Contractor's price for providing storage, including
          insurance and transportation to storage, shall be provided to Buyer
          within 30 days after receipt of Buyer's notice to store such
          Spacecraft and Contractor shall provide storage facilities.  If such
          storage facilities are unavailable, Contractor and Buyer shall hold
          discussions to determine a mutually agreed storage arrangement.
 
     31.2 Six (6) months prior to a stored Spacecraft's scheduled launch date,
          Buyer shall, by notice in writing, order the Contractor to remove said
          Spacecraft from storage and ship it to a Launch Site designated by
          Buyer.  The cost for storage and additional transportation costs
          exceeding that required to transport the satellite(s) to the FOB point
          specified herein, shall be borne by Buyer.  These will be in addition
          to any charges which become the obligation of the Buyer per Article 18
          herein entitled "Spacecraft Not Launched Within Six Months After
          Acceptance."

     31.3 Included in Contractor's price to be provided to HCG per Paragraph
          31.1 above shall be a price for the Contractor providing HCG the
          appropriate level of suggested maintenance of the stored Spacecraft
          for a period of up to one (1) year of storage. Contractor shall be
          responsible for risk of loss or damage to stored Spacecraft and
          associated batteries during the storage period.

Re: Galaxy-X and XI Spacecraft Letter Authorization

Dear Ms. Bay, 

1.   A.   Hughes Communications Galaxy, Inc. ("HCG") hereby amends Reference 1
          letter authorization by providing full authorization in the amount of
          ***** (FFP) to Hughes Space and Communications Company ("HSC") to
          proceed with the Galaxy X ("GX") Spacecraft in accordance with HSC's
          proposal (Ref. 2).

     B.   Additionally, this letter authorization provides a **** advance for
          the Galaxy XI ("GXI") Spacecraft to proceed in accordance with HSC's
          proposal (Ref. 2).

2.   In the near term, please provide appropriate efforts to support a Galaxy X
     Spacecraft available for a launch date of April-May 1998.  Such efforts
     should include the following:

     A.   Develop and submit a program payment schedule.

     B.   Develop and submit a Fixed Price Proposal for Galaxy XI by 15 December
          1995.

     C.   Continue to work with HCG to finalize baseline payload specification,
          allowing for payload design and early definition of requirements
          ("EDOR") to be completed by 15 December 1995.  The baseline payload
          specifications shall be consistent with the following:

          C-band:   30 for 24 redundancy utilizing SSPAs to achieve EIRP of 38
                    to 41 dBW (for GX and GXI).

          Ku-band:  30 for 24 redundancy utilizing TWTAs to achieve EIRP of 47
                    to 51 dBW CONUS (for GX and GXI) and greater than (>) 46 dBW
                    Alaska (for GX only).

     D.   Support HCG selection of candidate additional payload option(s)
          through 29 February 1996.  Total payload power demand shall be limited
          to twelve thousand (12,000) watts for the HS-702 Spacecraft.  The
          payload option, if any, shall be selected by HCG no later than 29
          February 1996 for Galaxy X and by 1 October 1996 for Galaxy XI.

     E.   Any resultant Acquisition Agreement shall include both Galaxy X and
          Galaxy XI Spacecraft.  However, if the Galaxy X contractual documents
          are ready for signature prior to the Galaxy XI, then the parties will
          sign the Galaxy X contract and add Galaxy XI as a contract amendment.

The following Articles shall apply to this Letter Authorization:

3(A).  Letter Authorization Funding for Galaxy X:
- -------------------------------------------------

Consistent with the referenced proposal, HCG will pay in accordance with the
schedule listed below.  The final payment plan will be provided by 15 December
1995.

     October 1995   ************
     November 1995  ************
     December 1995  ************

3(B).  Letter Authorization Funding for Galaxy XI:
- --------------------------------------------------

An advance of ******** is hereby authorized.

4.    Letter Authorization Amendment:
- -------------------------------------

This Letter Authorization amends the referenced Letter Authorization (Ref. 1).

5.    Terms and Conditions:
- ---------------------------

This Letter Authorization is subject to the terms and conditions agreed to under
the Galaxy IX Spacecraft Acquisition Agreement (excluding liquidated damages)
and Attachment A hereto, until such other terms and conditions are negotiated
and accepted between the parties.

Because the HS-702 design is solely dependent on the new 25 cm XIPS for post LAM
transfer orbit and on-station operations, a fallback design alternative, which
preserves HCG's Galaxy X delivery requirement, must be included in any resultant
contract. In addition, any resultant Contract should provide scheduling
flexibility for the Galaxy XI Spacecraft, as it is intended to be a spare for
the Galaxy X Spacecraft.

          becomes chargeable to any work terminated plus all reasonable
          reprocurement costs up to a maximum amount of **********************
          ***************; or ii) receive a refund of *************************
          ***************************************************** and Contractor

          delay, there shall be an equitable adjustment to the time of delivery
          and/or performance stated in this Contract.  The affected Party shall
          give notice to the other Party within 10 working days that an

          notification shall include the cause of the excusable delay, the
          expected length of the excusable delay, and alternate plans to
          mitigate the effect of the excusable delay.

          or experiences, on a cumulative basis, excusable delay(s) greater than
          ******** ***** days, the Parties shall enter into good faith
          negotiations to develop a mutual course of action and/or an equitable
          adjustment to the affected terms of this Agreement.

     12.3 Notwithstanding the foregoing, if the Launch Date defined in

          the Launch Site has occurred, HCG shall reimburse Contractor for all
          reasonable expenses.  Expenses included in any equitable adjustment
          shall include but not be limited to; support personnel standby;  extra
          travel expenses; transport termination or rescheduling fees; and
          installation/de-installation of communication links to the Launch Site

          process inventories generated under this Contract, with respect to the
          terminated work, shall become the property of HCG.  HCG shall direct
          disposition of such property within sixty (60) days from date of

          sale to third Parties and/or internal utilization) for any Hardware
          affected by a termination under this Article 14, the Contractor shall
          submit a proposal to HCG, which, at a minimum, defines i) the
          applicable Hardware; ii) the intended use of the Hardware; iii) the

               Partial Failure, Total Failure or Total Constructive Failure of
               the Spacecraft, as defined in the applicable HCG Launch Insurance
               Contract, whichever occurs first.

          2.   In respect to a Spacecraft which HCG directs Contractor to store,
               the Parties shall negotiate in good faith as to the transfer of
               Title and Risk of Loss for the Spacecraft.

          3.   Notwithstanding Paragraph 15.1.2 above, upon removal of the
               Spacecraft from storage, the Contractor shall not assume Risk of
               Loss relative to a Battery which HCG directs Contractor to
               replace after the five-year storage period which disqualifies the
               battery for a fifteen (15) year mission.  In that event, Article
               29 herein entitled "Effects of Storage on Batteries," shall
               apply.

     15.2 In the event of damage to or destruction of Hardware when
          Contractor shall have Risk of Loss, Contractor shall repair or
          replace (at Contractor's option) said Hardware. The Buyer shall
          participate in the decision to repair or replace said Hardware.

ARTICLE 16.    SPACECRAFT WARRANTY
               -------------------

    16.1  Contractor warrants that a Spacecraft, upon successful completion of
          Spacecraft in-plant Tests pursuant to Article 9 herein, shall be free
          from any defects in material or workmanship and shall conform to the
          applicable specifications and drawings, as evidenced by acceptance
          criteria, as defined in Exhibit D.

    16.2  HCG shall have the right at any time during the period of this
          Warranty to reject any goods not conforming to this Warranty and
          require that Contractor, at its expense, correct or replace (at
          Contractor's option) such goods with conforming goods. If Contractor
          fails to correct or replace such defective goods and fails to initiate
          reasonable efforts to correct or replace such defective goods within a
          reasonable period after notification and authorization from HCG, HCG
          may then, by contract or otherwise, correct or replace such defective
          goods and equitably adjust the price.

    16.3  This Warranty shall start from the date of Preliminary Acceptance of a
          Spacecraft as stated in Article 9 herein, entitled "Inspection and
          Acceptance," and continue for a period of ********** or until the
          Intentional Ignition (defined herein as the "Intentional Ignition of
          any rocket motor on the first stage of the launch vehicle by the
          applicable launch provider") of the applicable launch vehicle, 
          whichever is earlier. **************************************
          ************************************************************
          ************************************************************
          ************************************************************
          Contractor shall not be liable in Contract or in tort for any
          incidental, special, contingent, or consequential damages.

    16.4  Except as otherwise expressly agreed upon in this Contract, Contractor
          shall have no liability, or responsibility in Contract or in tort with
          respect to a Spacecraft after Intentional Ignition (as defined in
          Paragraph 16.3) of the launch vehicle.

          officers, agents, servants, subsidiaries, and employees, or any of
          them, harmless from any liability or expense in connection herewith on
          account of damage to property (excepting Spacecraft in flight) and
          injuries, including death, to all persons including but not limited to
          employees of the Parties, and their subcontractors, and of all other
          persons performing any part of the work hereunder, arising from any
          occurrence caused by an negligent act or omission of the indemnifying
          Party or its subcontractors, or any of them in connection with the
          work to be performed by such Party under this Contract.  The
          indemnifying Party shall have the right, but not the obligation, to
          participate in any legal or other proceedings concerning claims for
          which it is indemnifying under this Article 17 and to direct the
          defense of such claims.  However, with respect to such legal or other
          proceedings, the indemnifying Party shall pay all expenses (including
          attorneys fees incurred by the indemnified Party in connection with
          such legal or other proceedings) and satisfy all judgments, costs or
          other awards which may be incurred by or rendered against the
          indemnified Party.  The indemnifying Party shall not settle any such
          claim, legal or other proceeding without first giving thirty (30) days
          prior written notice of the Terms and Conditions of such settlement
          and obtaining the consent of the indemnified Party, which consent
          shall not be unreasonably withheld or delayed.

    17.2  Notwithstanding the foregoing, neither the Contractor nor its
          subcontractors shall have any liability in contract or in tort, for
          damages to or caused by the Spacecraft after Intentional Ignition (as
          defined in Paragraph 16.3), and HCG shall obtain waivers of
          subrogation rights from Buyer's insurers against Contractor, and
          affiliates and subcontractors of Contractor.

    17.3  In no event shall the Contractor or Buyer be liable for any
          incidental, special, contingent or consequential damages (including,

ARTICLE 18.    SPACECRAFT NOT LAUNCHED WITHIN SIX MONTHS AFTER ACCEPTANCE
               ----------------------------------------------------------

    18.1  If the Spacecraft is not launched within six (6) months after its
          Preliminary Acceptance per Article 9, entitled "Inspection and
          Acceptance," and is subsequently ordered to be launched within one (1)
          year following its Preliminary Acceptance, it is agreed that such
          Spacecraft may be returned, at Contractor's option and at Contractor's
          expense, to Contractor's facility for inspection and refurbishment.
          Any inspection and refurbishment undertaken by Contractor to meet the
          requirements of Article 16 entitled, "Spacecraft Warranty," shall be
          at Contractor's expense, including Spacecraft transit insurance.

    18.2  If the Spacecraft is not launched within six (6) months after its
          Preliminary Acceptance and is subsequently ordered to be launched
          later than one (1) year following its Preliminary Acceptance, it is
          agreed that such Spacecraft may be returned as mutually agreed, at
          HCG's expense, to Contractor's facility for inspection and
          refurbishment.  An equitable adjustment to Contract price for such
          inspection and refurbishment, to include a **** profit rate (or such
          other profit rate designated in writing by the Chief Financial Officer
          of the Hughes Space and Telecommunications Company (or then existing
          equivalent) for the applicable expenses) shall be negotiated by the
          Parties unless the fact that the launch is scheduled for later than
          one (1) year is due to Contractor's negligent acts or omissions.

    18.3  If the Spacecraft is returned to Contractor's facility for inspection
          and refurbishment per the terms of Paragraph 18.2 above, all charges
          to return such Spacecraft to the Launch Site shall be borne by HCG.

    18.4  If the Spacecraft has not been launched within five (5) years after
          its preliminary Acceptance, neither Party shall be further obligated
          to the other with respect to such Spacecraft.  Disposition of such
          Spacecraft shall be at the option of HCG with costs of such
          disposition to be borne by HCG.

ARTICLE 19.    PATENT/COPYRIGHT INDEMNITY
               --------------------------

    19.1  Contractor shall indemnify and hold HCG harmless against any
          liability or expense as a result of claims, actions, or proceedings
          against HCG alleging the infringement of any United States Letters
          Patent, or copyright of any data, or article fabricated by Contractor
          and delivered to HCG pursuant to this Contract as set forth below.

    19.2  Contractor agrees to defend at its own expense any request for
          royalty payments or any claim for equitable relief or damages against
          HCG, its officers, employees, agents, or subsidiaries based on an
          allegation that the manufacture of any item under this Contract or the
          use, lease, or sale thereof infringes any United States Letters
          Patent, and to pay any royalties and other costs related to the
          settlement of such request and to pay the costs and damages, including
          reasonable attorney's fees finally awarded as the result of any suit
          based on such claim, provided that Contractor is given prompt written
          notice of such request or claim by HCG and given authority and such
          assistance and information as is available to HCG for resisting such
          request or for the defense of such claim.  Any such assistance or
          information which is furnished by HCG at the written request of
          Contractor is to be at Contractor's expense.

    19.3  In the event that, as a result of any such suit: a) prior to
          delivery, the manufacture of any item is enjoined; or b) after
          delivery, the use, lease or sale thereof is enjoined, Contractor
          agrees to utilize its best effort to either: (1) negotiate a license
          or other agreement with plaintiff so that such item is no longer
          infringing; or (2) modify such item suitably or substitute a suitable
          item therefore, which modified or substituted  item is not subject to
          such injunction, and to extend the provisions of this Article thereto.
          In the event that neither of the foregoing alternatives is suitably
          accomplished by Contractor, Contractor shall be liable to HCG for
          HCG's additional costs and damages arising as a result of such
          injunction; provided however, that in no event shall Contractor's
          entire liability under this Article exceed ********* U.S. Dollars
          (*********).

          agreement at least as restrictive as this Article 21 and furnishes a

ARTICLE 28.    CHANGES
               -------

     Between the Effective Date of Contract and completion of performance under
     this Contract, Buyer shall have the right to make changes within the
     general scope of this Contract in drawings, designs, specifications, method
     of shipment or packing, or change the place of delivery, require additional
     work, or direct the omission of work.  Any such changes must be made in
     writing and must be signed by HCG's Authorized Representative.  If any such
     change causes an increase or decrease in the cost of, or the time required
     for, the performance of this Contract, or otherwise affects any other
     provision of this Contract, an equitable adjustment to be negotiated in
     good faith shall be made in the price, or delivery date or schedule, or
     both, and such other terms as may be affected, and this Contract shall be
     amended in accordance with Article 13 entitled "Amendments," herein.  If
     the cost of supplies or materials made obsolete or excess as a result of a
     change is included in Contractor's claim for adjustment, HCG shall have the
     right to prescribe the manner of disposition of such supplies or materials.
     Nothing in this Article shall excuse Contractor from promptly proceeding
     with the Contract as changed.

ARTICLE 29.    EFFECTS OF STORAGE ON BATTERIES
               -------------------------------

     For Spacecraft batteries to provide the required minimum fifteen (15) years
     of in-orbit services per Exhibit B, Galaxy VIII-I Spacecraft Specification,
     it is understood that launch must occur within five (5) years from the date
     of activation of the first battery cell.  In the event Buyer directs
     Contractor to store any deliverable Spacecraft and the period of such
     storage causes a launch later than five (5) years from the date of
     activation of that Spacecraft's first battery cell and HCG directs
     Contractor to install replacement batteries to meet fifteen (15) year in-
     orbit service requirement, then HCG shall pay Contractor its costs plus a
     **** profit rate or such other profit rate designated in writing by the
     Chief Financial Officer of the Hughes Space and Telecommunications Company
     (or then existing equivalent) for the applicable expenses for replacing
     batteries per Buyer's direction.

ARTICLE 30.    INTER-PARTY WAIVER OF LIABILITY
               -------------------------------

         30.1  Prior to the time HCG and the Contractor enter the premises at
               the Launch Site, they each agree that they will not make a claim
               against each other for damage to, loss of, or loss of use of
               their property or the property of others in their possession,
               caused by the fault of negligence of the other Party to this
               Contract, or otherwise caused by any defect in any product
               manufactured or sold by the other Party to this Contract.  Such
               claims are waived and each Party will bear its own losses.  HCG
               will include a comparable clause in each of its contracts with
               vendors, subcontractors or customers for services or benefits
               expected as a result of the launch or orbiting of Galaxy Follow-
               on satellites.  Such comparable clause shall include a
               requirement to flow the clause down to lower-tier contractors.

         30.2  Notwithstanding any other provisions of this Contract, prior to
               the time any Party, associated with the Galaxy VIII-I launch
               activities at the Launch Site, shall enter the premises at the
               Launch Site, such Parties shall be required to sign an Inter-
               Party Waiver of Liability consistent with that between HCG and
               the Contractor as incorporated herein under Paragraph 30.1 of
               this provision or other similar agreement as may be required by
               the launch agency.  Each Party shall have the responsibility to
               assure that all the Parties associated with the launch of the
               Galaxy VIII-I Spacecraft (for which they have control or privity
               of Contract with hereunder) have executed said Inter-Party Waiver
               of Liability.

ARTICLE 31.    SPACECRAFT STORAGE
               ------------------

         31.1  Buyer may, at its option, order Contractor to store, in
               accordance with the provisions of Exhibit B Galaxy VIII-I
               Spacecraft Specification, the deliverable Spacecraft (including
               separate storage of Batteries, if needed) for a period of up to 1
               year from the date of their delivery to Buyer.  HCG shall provide
               written notice to the Contractor not later than six (6) months
               prior to the scheduled delivery of said Spacecraft.  Contractor's
               price for providing storage, including insurance and
               transportation to storage, shall be provided to Buyer within 30
               days after receipt of Buyer's notice to store such Spacecraft and
               Contractor shall provide storage facilities.  If such storage
               facilities are unavailable, Contractor and Buyer shall hold
               discussions to determine a mutually agreed storage arrangement.

         31.2  Six (6) months prior to a stored Spacecraft's scheduled launch
               date, Buyer shall, by notice in writing, order the Contractor to
               remove said Spacecraft from storage and ship it to a Launch Site
               designated by Buyer.  The cost for storage and additional
               transportation costs exceeding that required to transport the
               satellite(s) to the FOB point specified herein, shall be borne by
               Buyer.  These will be in addition to any charges which become the
               obligation of the Buyer per Article 18 herein entitled
               "Spacecraft Not Launched Within Six Months After Acceptance."

         31.3  Included in Contractor's price to be provided to HCG per
               Paragraph 31.1 above shall be a price for the Contractor
               providing HCG the appropriate level of suggested maintenance of
               the stored Spacecraft for a period of up to one (1) year of
               storage.  Contractor shall be responsible for risk of loss or
               damage to stored Spacecraft and associated batteries during the
               storage period.

ARTICLE 32.    DISPUTES
               --------

     32.1  Disputes

           32.1.1   In the event any dispute arises between the Contractor and
                    the Buyer relating to this Contract, either Party may give
                    written notice to the other of its objections and reasons
                    therefore. The Contractor's Program Manager shall consult
                    with HCG's Spacecraft Acquisition Manager in an effort to
                    reach a mutual agreement to resolve such dispute. In the
                    event mutual agreement cannot be reached within fifteen (15)
                    days after receipt of this notice, the respective positions
                    of the Parties shall be forwarded to the Contractor's
                    Business Unit Leader and HCG's President for discussions and
                    attempt to reach mutual agreement to resolve such dispute
                    within another fifteen (15) day period.

           32.1.2   In the event mutual agreement cannot be reached within the
                    time period defined in Paragraph 32.1.1 above, the positions
                    of the Parties shall be forwarded to the Contractor's and
                    Buyer's Sector Executive Office.  If mutual agreement cannot
                    be reached, such dispute may be referred on the application
                    of either Party for final determination to an arbitration
                    tribunal convened in accordance with the American
                    Arbitration Association rules for commercial arbitration.

     32.2  Arbitration of Disputes

           32.2.1   Any dispute, disagreement, controversy or claim arising out
                    of or relating to this Contract or the interpretation
                    thereof or any arrangements relating thereto, or the
                    validity or enforceability thereof, or contemplated therein
                    or the breach, termination or invalidity thereof which is
                    not settled to the mutual satisfaction of the Parties in
                    accordance with Paragraph 32.1 above, shall be settled
                    exclusively and finally by arbitration.

ARTICLE 34.    ASSIGNMENT
               ----------

    34.1  Neither Party shall assign, or transfer this Contract or any of its
          rights, duties or obligations thereunder to any person or entity, in
          whole or part without the prior written consent of the other Party
          except that either Party may assign or transfer any of its rights,
          duties or obligations under this Contract, either in whole or in part,
          to its parent company or a subsidiary in which the assigning Party has
          a controlling interest thereof.

          Neither Party shall unreasonably withhold consent to any assignment or
          transfer providing that the requesting Party can demonstrate to the
          other Party's satisfaction that:

          (1)  its successor or assignee possesses the financial resources to
               fulfill the obligations of this Contract; and

          (2)  any such assignment or transfer shall not jeopardize any data
               rights or competitive position, or violate laws related to export
               or technology transfer, or otherwise increase the other Party's
               risks or obligations.

          If the requesting Party cannot so demonstrate, both Parties agree to
          negotiate in good faith suitable modifications and new provisions to
          this Contract which would mitigate the above risks and/or bring this
          Contract into conformance with applicable laws.

    34.2  The Parties agree that in the event that the ownership or control of
          HCG is changed, Contractor reserves the right to negotiate in good
          faith suitable modifications and new provisions to this Contract which
          would mitigate any additional risks, financial or otherwise, to
          Contractor which may be brought about by such change in ownership or
          control.

    34.3  This Contract shall be binding upon the Parties hereto and their
          successors and permitted assigns.

          SECTION 2.05.  Closing Date Appraisal; Commencement Date Appraisal;
                         ----------------------------------------------------
Commencement Date Adjustments.
- ----------------------------- 

          (a)  Closing Date Appraisal.  HCG has caused to be delivered to Owner
               ----------------------                                          
Participant an appraisal, dated as of the Closing Date, by Independent
Appraiser, addressed to Owner Participant and in a form and substance
satisfactory to Owner Participant, which appraisal contained (i) the
determination of Independent Appraiser of the anticipated fair market value of
each Transponder as of the anticipated Commencement Date, (ii) an estimate of
the remaining useful economic life of each Transponder as of the anticipated
Commencement Date, (iii) the conclusion that each Transponder shall have a
residual value of not less than 20% of Lessor's Cost (without taking into
account the effect of inflation or deflation) at the end of the Basic Term, (iv)
the conclusion that no Transponder is "limited use property" and (v) a statement
that the fees payable under the Service Agreement are equal to the fair market
value of the services to be provided thereunder (the "Closing Date Appraisal").
                                                      ----------------------    
The Closing Date Appraisal also stated Independent Appraiser's estimate as of
the Closing Date of the expected fair market value of each Transponder on the
EBO Date (taking into account a reasonable estimate of the effect of inflation
and deflation).  Owner Participant acknowledges receipt of the Closing Date
Appraisal.

                                       5
<PAGE>
 
          (b)  Commencement Date Appraisal.  (i) As promptly as practicable but
               ---------------------------                                     
in no event later than the Commencement Date, HCG shall cause to be delivered to
Owner Participant and HCG an amendment by Independent Appraiser to the Closing
Date Appraisal, dated the Commencement Date, reasonably satisfactory in form and
substance to Owner Participant and HCG (the "Commencement Date Appraisal")
                                             ---------------------------  
stating whether or not, on the Commencement Date, the conclusions of the Closing
Date Appraisal are true or whether there are necessary amendments to the
conclusions of the Closing Date Appraisal. Such amendments, if any, to the
conclusions of the Closing Date Appraisal shall be based solely on changes in
the assumptions regarding the physical characteristics (including defects) of
the Satellite and the Transponders manifesting themselves following the launch
(which characteristics are referred to in Appendix D to the Closing Date
Appraisal), and may not take into account any factors or conditions whatsoever
other than the physical characteristics described above; in particular, all
other assumptions and methodologies will remain constant. If there are
adjustments to the Closing Date Appraisal conclusions, then Lessor's Cost, the
Basic Term, and Fair Market Sales Value on the EBO Date shall be adjusted, as
appropriate; provided that Lessor's Cost derived from the Commencement Date
             --------
Appraisal for the Transponders collectively will not exceed $300 million and the
Lease Term (exclusive of any Renewal Term) will not be extended beyond eight
years.

          (ii) On or prior to the proposed Commencement Date, HCG shall have
caused to be delivered to each Loan Participant a copy of the relevant sections
of the opinion referred to in clause (i) of Section 3.02, reasonably
satisfactory in form and substance to the Agent, which set forth Independent
Appraiser's estimate of the fair market value of each Transponder as of the
anticipated Commencement Date.

          SECTION 2.06.  Defaulting Participant.  In case Owner Participant
                         ----------------------                            
shall fail to make any amount of its Commitment available on the Commencement
Date (a "Defaulting Participant"), no Loan Participant shall have any obligation
         ----------------------                                                 
to make any amount of its Commitment available on such date or to increase any
amount of its Commitment.  If, for any reason, any one or more of the Loan
Participants shall fail to pay all or any portion of its Commitment on the
Commencement Date (a "Defaulting Participant"), Chemical Bank shall increase the

will be a party has been duly authorized by all necessary corporate action on
the part of, and has been or on or prior to the Commencement Date will be duly

(i) requires any approval of stockholders or approval or consent of any trustee
or holders of any of its indebtedness or obligations, (ii) contravenes any law,
judgment, governmental rule or regulation or order applicable to or binding on
it or any of its properties, the contravention of which would have a material
adverse effect on the conduct of its business and operations as presently
conducted or the performance of its obligations under the Operative Documents

consummation by it of any of the transactions (including, without limitation,
the sale of the Transponders pursuant to the Bill of Sale and the Purchase
Agreement and the operation of the Transponders pursuant to the Lease from and
after the Commencement Date) contemplated thereby, nor the sale of the
Transponders by Owner Participant to Owner Trustee, requires the consent,
approval or authorization of, the giving of notice to, or the registration with,
the recording or filing of any document with, or the taking of any other action
in respect of, any Governmental Body, including any requirement to file
notifications under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,

Commencement Date, any and all notifications that may be required to be given by
HCG to the FCC pursuant to the foregoing clause (iii) are routine in nature and
for informational purposes only, and no such notice as of the Commencement Date
requires any official action or determination by the FCC as of the Commencement
Date, is subject to approval or disapproval by the FCC or as of the Commencement
Date gives rise to a right by any party to file a petition to deny.

          (d)  Each Operative Document and Hughes Agreement to which HCG is or
will be a party constitutes or, when executed, will constitute the legal, valid
and binding obligation of HCG, enforceable against HCG in accordance with its
terms, except as such enforcement may be subject to bankruptcy, insolvency,
moratorium or other similar laws affecting creditors' rights generally and to
general principles of equity.

          (e) Except as disclosed in writing to Agent, Owner Trustee, Owner
Participant and Loan Participants prior to the execution of this Agreement,
there are no actions, suits or proceedings pending against HCG in any court or
before any arbitrator of any kind or before or by any Governmental Body, or to
the knowledge of HCG threatened, which question the legality or validity of any
of the Operative Documents or Hughes Agreements to which HCG is or will be a
party or the transactions contemplated thereby or which, individually or in the
aggregate, if adversely determined, would have a material adverse effect on the
conduct of its business and operations as presently conducted or on its ability
to perform its obligations under the Operative Documents or the Hughes
Agreements to which it is or will be a party on or prior to the Commencement
Date.

          (f)  HCG is not in violation of any Order, which violation would have

and marketable title to the Transponders, free and clear of all Liens other
than, until receipt of such payment by Seller, the right of Seller to payment of
the purchase price for the Transponders in the amount of Lessor's Cost therefor.

Owner Trustee, the GMAC Bill of Sale and the Trust Assignment are in the
appropriate forms for the effective conveyance by GMAC to Owner Trustee of all
of its right, title and interest in the Transponders and the assignment by GMAC

have been duly filed or recorded (or delivered to counsel for Agent for filing
or recording); and (ii) all Uniform Commercial Code financing statements and
other documents (other than any Operative Documents or Hughes Agreements)

Operative Documents and the Hughes Agreements, the extension by Loan
Participants of the Loans, and the acquisition by Owner Participant of its
beneficial interest in the Lessor's Estate will involve any prohibited
transaction within the meaning of Section 406(a) of ERISA or Sections

reliance upon and subject to the accuracy of the representations contained in

by holders of the Notes pursuant to such Notes.

     prior written notice of such appointment (including notification of the
     principal place of business of each such successor, additional or separate

     Participant shall cause any such successor, additional or separate trustee,

     practicable in the case of the Transponders) Lessee's

     Participant, the expenses incurred in connection with the appointment of a
     successor Owner Trustee as a result thereof shall be paid by Lessee.

     instruct or otherwise direct Owner Trustee to take, or omit to take, any
     action in violation of the express covenants and agreements of Owner
     Trustee in any Operative Document or any of the Hughes Agreements.  Owner
     Participant will not unreasonably withhold its consent to or authorization

              ------------------------------                                    
     of Agent, prior to the expiration or earlier termination of the Lease

     Collateral Security or limit in any material manner the rights of Agent or
     Loan Participants set forth in the Loan Agreement (except as may be
     expressly permitted by the Loan Agreement). If the Trust Agreement is
     revoked or terminated, any transfer of the Transponders in connection
     therewith shall comply with the applicable provisions of 

                                      29

     become a Competitor, or if Owner Participant has become a Competitor, or if
     Owner Participant has Actual Knowledge of any such event or condition that

     Participant will, as promptly as practicable (taking into account the
     effect of Applicable Laws on whether or not any such event or condition has
     been previously publicly disclosed), deliver to Lessee an Officer's
     Certificate of Owner Participant confirming or denying such event or
     condition and whether Owner Participant has become a Competitor.  If Owner
     Participant confirms such event or condition, Owner Participant shall take
     all reasonable measures with respect to all confidential and Proprietary
     Information necessary to protect Lessee from any adverse competitive impact
     that could arise from disclosure of such information.  Owner Participant
     acknowledges that Lessee will suffer irreparable harm in the event Owner
     Participant does not comply with its obligations under this Section 5.02(h)
     and agrees that Lessee shall be entitled to specific performance of such
     obligations.

          (i) Election to Retain Title.  If Owner Trustee shall elect or shall
              ------------------------

     amount of funds available to Owner Trustee and will otherwise cause Owner
     Trustee to perform its obligations under such Section 8(a) or 8(c) in
     accordance with the terms thereof.

          (j) Notice of Loan Event of Default.  Promptly after Owner Participant
              -------------------------------                                   
     has Actual Knowledge that any Loan Event of Default or Loan Default
     attributable to Owner Participant has occurred and is continuing, Owner
     Participant shall deliver to Agent and Lessee a notice of such Loan Event
     of Default or Loan Default describing the same in reasonable detail and,
     together with such notice or as soon thereafter as possible, a description
     of the action that Owner Participant has taken, is taking and proposes to
     take with respect thereto.

          SECTION 5.07.  Lessee's Instructions to Owner Trustee. Owner Trustee
                         --------------------------------------               
hereby agrees, so long as no Lease Event of Default shall have occurred and be
continuing, (a) to follow Lessee's written requests as soon as practicable (and
not to take any action not so requested) with respect to (i) selecting interest
rates and interest periods to be applicable to the Notes under the Loan
Agreement and prepayments of the Notes in connection with Sections 2.9 and 2.10
of the Loan Agreement and (ii) giving any and all notices under the Loan
Agreement to Agent or the Noteholders necessary or appropriate in order to
effectuate such selection of interest periods and such prepayment of the Notes,
provided that any such prepayment is effected in connection with a refinancing
pursuant to this Agreement or a prepayment contemplated by Section 2.9 or 2.10
of the Loan Agreement, and (b) to allow Lessee, to the exclusion of Owner
Trustee, to deliver Instruction Certificates under Section 19 of the Loan
Agreement.

          SECTION 5.08   Tax Indemnification Agreement.  Owner Participant and
                         -----------------------------                        
Lessee hereby covenant that if, during the Interim Term or the Basic Term, an
event occurs that results in Owner Participant's and Lessee's failing to remain
members of the same consolidated group for United States income tax purposes,
Owner Participant and Lessee shall negotiate in good faith the terms of and
enter into a Tax Indemnification Agreement pursuant to which Lessee will
indemnify the Owner Participant for certain losses of United States income tax
benefits caused by certain acts or omissions of Lessee.  If a dispute arises
between Owner Participant and Lessee regarding the proposed terms of the Tax
Indemnification Agreement, such dispute shall be resolved by the Tax Arbitrator,
whose decision will be final, binding, non-appealable, fully enforceable and
subject to being reduced to judgment by any court of competent jurisdiction.  In
no event will Lessee's obligations under the Tax Indemnification Agreement
result in a decrease in the amount of the Base Rent payable on any Rent Payment
Date to a level below the amount of scheduled principal repayment on the Notes,
together with accrued and unpaid interest thereon, on such Rent Payment Date.
The provisions of this Section 5.08 are not assignable by Initial Owner
Participant to any Person, other than a Person which is a member of General
Motors' Affiliated (without giving effect to the last sentence of the definition
thereof) group for United 

                                      33

States income tax purposes, without the prior written consent of Lessee.

                               General Indemnity
                               -----------------

          SECTION 6.01.  Payment of Expenses by Lessee.  (a)   Lessee shall pay
                         -----------------------------                         
(except to the extent that any of the items hereinafter described are expressly
made payable by Owner Participant pursuant to Section 9.01), and shall indemnify
and hold harmless each Indemnitee (whether or not any of the transactions
contemplated hereby shall be consummated) on an After-Tax Basis from, any and
all liabilities, obligations, losses, damages, reasonable attorneys' fees,
penalties, claims, actions, suits, costs, expenses and disbursements (other
than, as to any particular Indemnitee, any of those specifically provided for in
Article VII hereof and the Tax Indemnification Agreement, if any), including,
without limitation, any reasonable expenses incurred by any Indemnitee in
furnishing any reports required pursuant to the Communications Act or any other
provision of Applicable Law with respect to this Agreement or the transactions
contemplated hereby (herein collectively referred to as "Expenses" and
                                                         --------     
individually as an "Expense") imposed on, incurred by or asserted against any
                    -------                                                  
Indemnitee (whether because of an action or omission by such Indemnitee or
otherwise), in any way relating to or arising out of (i) any of the Satellite,
the earth stations related thereto, or the Transponders or any part thereof or
any interest therein, (ii) the Operative Documents, or the Hughes Agreements or
payments made pursuant thereto or any other transactions contemplated thereby
and (iii) the manufacture, launching, financing, refinancing, construction,
purchase, acceptance, rejection, delivery, nondelivery, ownership, acquisition,
lease, sublease, preparation, installation, assembly, storage, maintenance,
repair, transportation, abandonment, possession, repossession, use, operation,
condition, sale, return, replacement, redelivery, modification, transfer of
title, rebuilding, rental, importation, exportation or other application or
disposition of all or any part of or any interest in any of the Transponders or
the Satellite or the earth stations related thereto, including, without
limitation, (A) claims or penalties arising from any violation of law or
regulatory requirements of any kind relating solely to Indemnitee's interest in
the Transponders or the Satellite or liability in tort, strict or otherwise, (B)
loss of or damage to any property, the environment or death or injury to any
Person, (C) latent or other defects, whether or not discoverable, (D) any claim
for patent or trademark or copyright infringement, libel or slander, including
any such claim arising from transmissions to or from the Satellite or any

to Owner Trustee (and its successors, assigns, officers, directors, servants,
employees and agents), Owner Participant Liens, with respect to Owner

Participant (and its successors, assigns, officers, directors, servants,
employees and agents), and Agent Liens, with respect to Agent (and its
successors, assigns, officers, directors, servants, employees and agents)) and
(F) claims, penalties or liabilities in respect thereof based on any other
theory of liability. Upon payment in full of any indemnity pursuant to this
Section 6.01, Lessee shall, to the extent permitted by Applicable Law (except
with respect to Additional Insurance maintained by such Indemnitee at its own
expense pursuant to Section 9(c) of the Lease), be subrogated to any right of
such Indemnitee in respect of the matter against which such indemnity has been
paid to the extent of such payment. Owner Trustee shall be subrogated to any
rights of Agent or the holder of any Note (other than any security interest) to
the extent any amount otherwise payable to Owner Trustee under the Loan
Agreement shall be reduced by the failure of Lessee to have paid any indemnity
to Agent or such Noteholder.

          (b) Without limitation of the foregoing, Lessee shall pay on an After-
Tax Basis (except to the extent such amounts are payable by Owner Participant as
part of its Commitment, or by Owner Participant pursuant to Section 9.01 (unless
specified otherwise in such Section 9.01)) all the out-of-pocket costs and
expenses (including, without limitation, reasonable legal fees and expenses)
reasonably incurred by Owner Participant, Owner Trustee or Agent in connection
with (A) the entering into or giving or withholding of any future amendments,
supplements, waivers or consents (whether or not they become effective) with
respect to any Operative Document or the Hughes Agreements, other than those
that are made at the request of such Indemnitee or in connection with the
transfer of Owner Participant's interest in accordance with Article XIV hereof,
(B) the taking of any action under the Lease or the Loan Agreement at the
request of Lessee or as a result of an Event of Default or (C) any Event of
Loss, any redemption, prepayment or refunding of Notes, whether or not
consummated, in each case as permitted by the terms of the Operative Documents
subject, in the case of Agent, to the provisions of the Loan Agreement.

          (c) If Lessee or any Indemnitee has knowledge of any action, suit,
proceeding or claim hereby indemnified against under this Section 6.01 or any
action, suit, proceeding or claim seeking incidental or consequential damages
against such Indemnitee with respect to a Transponder subject to the Lease
whether or not indemnified against under this Section 6.01, it shall give prompt
written notice thereof to the other and Lessee may assume the defense thereof,
and, at such Indemnitee's request, shall assume the defense thereof with counsel
reasonably acceptable to such Indemnitee.  Such Indemnitee shall fully cooperate
with Lessee in all ways reasonably requested by Lessee in said defense by
Lessee.  In any such action, any Indemnitee shall have the right to employ
separate counsel in such action and participate therein, subject to the
preceding sentence, but 

                                      35
<PAGE>
 
the fees and expenses of such counsel shall be at the expense of such
Indemnitee, unless (i) the employment of such counsel has been specifically
authorized by Lessee, (ii) the named parties to such action (including any
impleaded parties) include both such Indemnitee and Lessee and representation of
such Indemnitee and Lessee by the same counsel would be unethical under the
applicable standards of professional conduct due to actual or potential
conflicting interests between them or (iii) such action involves an act that
involves or is alleged to involve criminal activity undertaken in compliance
with or as contemplated by the Operative Documents or Hughes Agreements or
involves the risk of criminal penalties, unless such action does not lead to the
commencement (including, without limitation, the impanelling of a grand jury or
similar investigatory proceeding) of a criminal proceeding. Lessee shall not be
liable for any settlement of any action, suit, proceeding or claim effected
without its written consent and (subject to clause (I) of the next following
sentence) no Indemnitee will agree to any such settlement without the prior
written consent of Lessee. Notwithstanding the foregoing, Lessee shall not be
entitled to assume responsibility for and control of any such judicial or
administrative proceedings, (I) unless Lessee has acknowledged responsibility
under this Section 6.01 for the Expense, provided that such acknowledgement
                                         --------
shall not be binding upon Lessee in the event of a final determination in any
judicial or administrative proceedings that Lessee was not responsible under
this Section 6.01 for the Expense or (II) while an Event of Default under the
Lease shall have occurred and be continuing, unless the Lessee posts a bond or
other security reasonably acceptable in form and substance to such Indemnitee.

          (d) Notwithstanding the provisions of the immediately preceding
paragraph, the omission by any Indemnitee to notify Lessee of any Expense shall
not relieve Lessee from any liability which it may have hereunder in respect of
any such Expense or other Expense; provided, however, that nothing herein
                                   --------  -------                     
contained shall prevent Lessee from bringing a subsequent action against such
Indemnitee for damage suffered by Lessee as a result of such omission.

          (e) If, by reason of any Expense payment made to or for the account of
an Indemnitee by Lessee pursuant to this Section 6.01, such Indemnitee
concurrently or subsequently realizes a tax deduction or credit not previously
taken into account in computing such payment, such Indemnitee shall promptly pay
to Lessee (but only after Lessee shall have made all payments then due and owing
to such Indemnitee under the Operative Documents), an amount equal to the sum of
(i) the actual reduction in Taxes realized by such Indemnitee which is
attributable to such deduction or credit plus (ii) the actual reduction in Taxes
                                         ----                                   
realized by such Indemnitee as a result of any payment made by such Indemnitee
pursuant to this sentence; provided, however, that such Indemnitee shall not be
                           --------  -------                                   
obligated to 

                                      36
<PAGE>
 
make any payment to Lessee pursuant to this sentence if and for so long as a
Payment Default, Bankruptcy Default or any Event of Default shall have occurred
and be continuing, but shall promptly make such payment once all such Payment
Defaults, Bankruptcy Defaults and Events of Default shall no longer be 
continuing; and provided further, however, that such Indemnitee shall not be
                -------- -------  -------                                   
obligated to make any payment pursuant to this Section 6.01 to the extent that
the amount calculated pursuant to (i) above would exceed (x) the amount of all
prior payments received by such Indemnitee from Lessee pursuant to this Section
6.01 with respect to such Expense (determined without regard to any amount paid
in respect of Taxes required to be paid by such Indemnitee in respect of the
receipt or accrual of such amounts) less (y) the portion of all prior payments
                                    ----
computed pursuant to (i) above paid by such Indemnitee to Lessee hereunder. Any
Taxes that are imposed on any Indemnitee as a result of a disallowance or
reduction of any tax benefit taken into account in the prior sentence shall be
treated as a Tax for which Lessee is obligated to indemnify such Indemnitee
pursuant to the provisions of Article VII hereof without regard to Section 7.02
(other than subsections (f) and (g) thereof) or Section 7.04 thereof.

          (f) In the event of a conflict between the provisions of Article 14 of
the Purchase Agreement or Article 6 of the Service Agreement and the provisions
of this Agreement, the provisions of this Agreement shall prevail.

          SECTION 6.02.  Exceptions.  The indemnity contained in Section 6.01
                         ----------                                          
with regard to any particular Indemnitee shall not extend to any Expense (a)
resulting from the willful misconduct or gross negligence of such Indemnitee
(other than willful misconduct or gross negligence imputed to such Indemnitee
solely by reason of its interest in the Transponders) or its respective
corporate successors, officers, directors, servants, agents or employees, (b) to
the extent resulting from the breach by such Indemnitee of any of its
representations, warranties or covenants in any of the Operative Documents or
the Hughes Agreements, (c) to the extent (i) attributable solely to acts or
events occurring after the end of the Lease Term which are not attributable to
Events of Default that were in existence during the Lease Term and were not
cured prior thereto or (ii) resulting from, in the case of Owner Participant
(and its successors, assigns, officers, directors, servants, employees and
agents), an Owner Participant Lien, in the case of Owner Trustee or Trust
Company (and its successors, assigns, officers, directors, servants, employees
and agents), a Lessor's Lien, and in the case of Agent (and its successors,
assigns, officers, directors, servants, employees and agents), an Agent Lien,
(d) which is a Tax, it being understood that all Tax indemnities are governed by
the Tax Indemnification Agreement, if any, or Article VII, and it being further
understood that this clause (d) shall not affect any express requirement in the
Operative Documents that any payments otherwise be made on an After-Tax Basis,
(e) as to Owner 

                                      37

Participant or Owner Trustee, resulting at any time directly or indirectly from
a voluntary disposition or transfer by Owner Participant or Owner Trustee of all
or any part of its right, title and interest in any of the Transponders or
Lessor's Estate or as to any Indemnitee, resulting at any time from such
Indemnitee's voluntary disposition of all or any part of such Indemnitee's
right, title and interest in and to any of the Transponders or any Operative
Document (except that this clause (e) shall not affect Lessee's obligations
under Section 6.01 in respect of any such disposition following the exercise of
remedies under Section 16 of the Lease in connection with an Event of Default
under Section 15 of the Lease or in connection with any disposition under
Section 8, 10, 11, 12 or 19 of the Lease except as otherwise expressly provided
in such Sections, the foregoing exception being referred to below as the "clause
(e) exception"), (f) expressly required under any Operative Document to be paid
by a party to this Agreement other than Lessee or as to which Lessee is
expressly exempted from liability under any Operative Document or (g) any
Expense of Agent arising out of or related to or in connection with any sale or
offer to sell to any Person, directly or indirectly, any interest in the
Lessor's Estate, the Transponders, or any of the Operative Documents (except
that this clause (g) shall not affect Lessee's obligations specified in the
clause (e) exception).

          Except as expressly provided in this Agreement or in any other
Operative Document, Lessee shall not be liable to any Indemnitee for incidental
or consequential damages suffered by such Indemnitee; provided, however, that
                                                      --------  -------      
the foregoing shall not be construed to limit recovery by any Indemnitee of any
costs, expenses or liabilities incurred and payable by such Indemnitee to a
third party as a result of any third party claim against such Indemnitee based
on events occurring and/or conditions existing any time prior to the expiration
or earlier termination of the Lease, except to the extent incurred by such
Indemnitee as a result of affirmative actions of such Indemnitee to market or
otherwise utilize any Transponders; provided, however, that nothing in this
                                    --------  -------                      
exception shall modify or limit Lessor's remedies under Section 16 of the Lease.
In no event shall any party hereto be liable to any other party for punitive or
exemplary damages.

          With respect to any amount which Lessee is requested by an Indemnitee
to pay by reason of this Article VI, the Indemnitee shall, if requested by
Lessee and prior to any payment, submit such additional information to Lessee as
Lessee may reasonably request properly to substantiate the requested payment.
Lessee covenants and agrees to pay all amounts due under this Article VI
promptly and in any event within 30 days of demand.  Nothing contained in this
Article VI shall increase, decrease or otherwise affect in any way Seller's or
Hughes Services' obligations under the Hughes Agreements in their respective
capacities as Seller and service provider thereunder.

the Operative Documents shall be free of Tax withholdings of any nature
whatsoever (and at the time that Lessee is required to make any payment upon
which any Tax withholding is required Lessee shall pay an additional amount such
that the net amount actually received by the Indemnitee entitled to receive such
payment will, after such withholding, equal the full amount of the payment then
due).  If any such Taxes are required to be withheld or deducted, Lessee shall
(A) pay such Taxes to the appropriate taxing authority on behalf of the
Indemnitee, and (B) as promptly as possible thereafter, provide the Indemnitee
(at the expense of Lessee) with an original receipt (or a copy thereof that has
been stamped by the appropriate taxing authority to certify payment) or other
reasonable proof of payment thereof.  Any withholding tax paid by Lessee that is
excluded from this Section 7.01 by Section 7.02 shall be promptly repaid to
Lessee by the appropriate Indemnitee.

          Except as provided in Section 7.02, whether or not the transactions
contemplated by the Operative Documents are consummated, Lessee hereby assumes
liability for and agrees to timely pay, and on written demand shall indemnify,
defend and hold each Indemnitee harmless, on an After-Tax-Basis, from and
against any and all Taxes actually imposed on or with respect to any Indemnitee,
Lessee, any Transponder or any part thereof or any interest therein, the
Satellite, or otherwise by any Federal, state or local government or any taxing
authority thereof in the United States or any territory or possession of the

at which the Satellite is located or the frequency spectrum at that point of

any part of or any interest in any of the Transponders, (b) the payment of Rent
or the receipts or earnings or profits arising from or received with respect to
any Transponder or any part thereof or any interest therein or any applications
or dispositions thereof or with respect to any Operative Document, (c) any
amount paid or payable pursuant to any of the Operative Documents or the Hughes
Agreements, (d) any Transponder or any part thereof or any interest therein or
the applicability of the Lease to such

Transponder or such part thereof or such interest therein, (e) the Operative
Documents, the Hughes Agreements, or any of them, (f) the property, the income
or other proceeds with respect to the property held by Owner Trustee or by Agent
under the Loan Agreement, (g) the original issuance of the Notes or any
refinancing thereof or the payment of the principal of, or interest on, the
Notes or other amounts payable under the Notes or the Loan Agreement or (h)
otherwise with respect to or in connection with the transactions contemplated by
the Operative Documents or the Hughes Agreements including, without limitation,
the issuance, acquisition or transfer of the Notes.

          SECTION 7.02.  Exceptions from Indemnity.  The provisions of Section
                         -------------------------                            
7.01 hereof shall not apply to:

          (a) (i) any withholding Tax functioning as a final tax in respect of
     any Noteholder that has not provided a current Internal Revenue Form 1001
     or Form 4224, to the extent applicable, and in any case a Form W-8 or W-9,
     to the extent applicable and (ii) any Tax on, based on, with respect to, or
     measured by net or gross income, capital or receipts of any Noteholder or
     which is in the nature of a franchise or conduct of business tax imposed on
     such Noteholder or which is in the nature of a minimum tax on tax
     preferences imposed on a Noteholder (in each case, other than a tax in the
     nature of a sales, use or rental tax); provided, however, that this clause
                                            --------  -------                  
     (ii) of subparagraph (a) shall not apply to any Taxes imposed by any state
     or local tax jurisdiction to the extent such Taxes arise in the applicable
     jurisdiction (other than with respect to net or gross income taxes,
     franchise taxes, conduct of business taxes or minimum taxes on tax
     preferences in the Noteholder's state or jurisdiction of incorporation or
     domicile or, with respect to a foreign Noteholder, the state in which the
     office used by such Noteholder to make or maintain the Loans is located)
     solely as a result of the Noteholder having executed, delivered or
     performed its obligations under the Operative Documents or having received
     a payment under the Operative Documents; provided, further, that with
                                              --------  -------           
     respect to a foreign Noteholder that is otherwise not a United States
     taxpayer, this clause (ii) of subparagraph (a) shall not apply to any Taxes
     to the extent such Taxes are United States federal Taxes and are imposed
     solely as a result of the Noteholder having executed, delivered or
     performed its obligations under the Operative Documents or having received
     a payment under the Operative Documents; and provided, still further, that
                                                  --------  ----- -------      
     Lessee shall not be obligated to pay any sales, use or rental tax in the
     nature of or imposed in lieu of a net income tax imposed on any Noteholder,
     that results from or is attributable to the fact that such Noteholder is a
     commercial bank or other financial institution organized under the laws of
     a jurisdiction other than the United States of America, or a state or
     territory thereof;

          (b) any Tax imposed by the United States Federal government based upon
     or measured by net income and any Tax on, based on, with respect to, or
     measured by the net income or gross income, capital, or net receipts of any
     Indemnitee (other than a Noteholder or the Agent), or which is in the
     nature of a franchise or conduct of business tax imposed on any Indemnitee
     (other than a Noteholder or the Agent) for the privilege of doing business,
     or which is in the nature of a minimum tax on tax preferences imposed on
     any Indemnitee (other than a Noteholder or the Agent) in each case by any
     state of the United States or by the United States Virgin Islands (other
     than any state in which Lessee or any Affiliate thereof owns or operates
     equipment used in connection with the operation of the Satellite or the
     Transponders other than, in the case of the Transponders, use by Lessee or
     any Affiliate thereof for internal purposes, unless such state is also the
     principal place of business of such Indemnitee, it being agreed that for
     purposes of this parenthetical clause the United States Virgin Islands
     shall be treated as a state) (in each case set forth in this subparagraph
     (b) other than a tax in the nature of a sales, use, value added, property,
     excise or rental tax); provided, however, that the provisions of
                            --------  -------
     subparagraphs (a) and (b) shall not apply to any Taxes imposed upon any
     indemnity payment made pursuant to Section 7.01 hereof, Article VI hereof
     or the Tax Indemnification Agreement, if any;

          (c)  in the case of Owner Participant, Owner Trustee or Lessor's
     Estate, for so long as no Event of Default shall have occurred and be
     continuing, any Tax that is imposed with respect to any Transponder with
     respect to any period beginning after the earlier of (i) the expiration of

     after such termination or expiration, or (ii) the discharge of Lessee's
     obligations to pay the Stipulated Loss Value or the Termination Value and
     all other amounts due under the Lease; provided, however, that this

     shall have occurred and be continuing, any Tax imposed with respect to (i)
     any period which begins after the payment of all amounts owing to such
     Noteholder under the Loan Agreement and (ii) the portion of any period
     which begins before such payment to the extent it occurs after such
     payment; provided, however, that this exception shall not apply to Taxes
              --------  -------

          (e) any Tax which is being contested in accordance with the provisions
     of Section 7.04, during the pendency of such contest; provided, however,
                                                           --------  -------
     that Owner Trustee, as Lessor under the Lease with respect to each
     Transponder, shall be receiving all amounts of Rent when payable, and that
     each Noteholder shall be receiving all payments of principal and interest
     on the Notes and all other amounts payable under the Notes and the Loan
     Agreement when payable, in either case without reduction by reason of such
     Tax or any other Tax;

          (f) any Tax (i) that is imposed on any Indemnitee or any Affiliate, or
     any successor, assign, officer, director, servant, employee or agent
     thereof, as a result of the willful misconduct or gross negligence, or a
     failure properly to file returns or statements, whether related or
     unrelated to the transactions contemplated by the Operative Documents or
     the Hughes Agreements (unless such failure results from Lessee's failure to
     provide timely notice of the requirement of such filing or the failure of
     Lessee to provide information reasonably required in connection with such
     filing or Lessee's failure to comply with its obligations under Section
     7.05), of such Indemnitee or such Affiliate thereof, or such successor,
     assign, officer, director, servant, employee or agent thereof (other than
     an act or failure to act required or contemplated under any of the
     Operative Documents or Hughes Agreements), (ii) that is imposed on any
     Indemnitee to the extent that such Tax results from the breach of any
     representation, warranty or covenant in the Operative Documents or Hughes
     Agreements by such Indemnitee, (iii) that is imposed on any Indemnitee as a
     result of a claim unrelated to the transaction contemplated herein, (iv)
     that is imposed on Owner Participant, Owner Trustee or Lessor's Estate
     because of or in connection with any Owner Participant Lien or Lessor Lien,
     respectively, (v) that is imposed on Agent because of or in connection with
     any Agent Lien (disregarding for such purpose the parenthetical language in

     Agreements (other than such a default that results from an Event of
     Default) by Owner Participant or Lessor, of any Transponder or any part
     thereof or any interest therein or Lessor's Estate; provided, however that

     this exception shall not

     apply (i) to the transfer of the Transponders by Initial Owner Participant
     to Owner Trustee pursuant to the GMAC Bill of Sale or (ii) in the event
     that such sale, transfer, assignment or other disposition shall occur as
     the result of any acts pursuant to Section 7, 8, 12, 16 or 19 of the Lease
     or at any time while an Event of Default, Payment Default or Bankruptcy
     Default shall have occurred and be continuing;

          (h) any Tax to the extent such Tax (i) would have been imposed on an
     Indemnitee had it not engaged in activities related to the transaction
     contemplated herein or (ii) is imposed by any jurisdiction that would not
     have imposed such Tax on the Indemnitee but for activities conducted by
     such indemnitee in such jurisdiction which activities are unrelated to the
     transactions contemplated herein (it being understood, however, for
     purposes of clause (ii) of this subparagraph (h), that, to the extent such
     tax is caused both by such activities of Indemnitee and by activities of a
     Lessee Person, such tax will be equitably apportioned between such
     Indemnitee and Lessee) or (iii) is a Tax referred to in Section 2.14 of the
     Loan Agreement;

          (i) any penalties, fines, additions to Tax and interest to the extent
     not attributable to a Tax indemnified against hereunder;

          (j) any estate, inheritance or succession Tax imposed on any
     Indemnitee; and

          (k) any Tax on, with respect to or measured by any trustee or agent
     fees received by Lessor, Owner Trustee or Agent for services rendered under
     the Trust Agreement or the Loan Agreement;

provided, however, that (i) if and to the extent any Tax referred to in any of
- --------  -------                                                             
the foregoing clauses would otherwise be indemnified against pursuant to the
terms of both the Tax Indemnification Agreement, if any, and this Article VII,
the terms of the Tax Indemnification Agreement, if any, shall control and no
payments shall be made under this Article VII, and (ii) the exclusions set forth
in subparagraphs (a) through (k) shall in no way apply to any Taxes imposed upon
the trust under the Trust Agreement or the Owner Trustee, as the case may be, to
the extent the trust under the Trust Agreement or the Owner Trustee, as the case
may be, as a result of the imposition of such Taxes, would not have sufficient
funds to make full payment on the Notes as and when due and payable.
Notwithstanding anything to the contrary herein or in any other Operative
Document, Lessee acknowledges and agrees to indemnify and hold harmless Owner
Participant and Owner Trustee against any and all withholding Taxes (inclusive
of any interest and penalties imposed for any failure to timely withhold such
Taxes) imposed on or with respect to any amounts paid to any Loan Participant or
any Noteholder or any successor, assign or

Affiliate thereof as to which Owner Trustee must indemnify pursuant to Section
2.17 of the Loan Agreement, as an indemnified Tax for purposes of this Section
7. Notwithstanding anything to the contrary contained in this Section 7.02, the
exceptions set forth in this Section 7.02 shall not apply, with respect to Owner
Trustee, Owner Participant or the Lessor's Estate, to any Taxes imposed by way
of withholding on payments of principal, interest or Break Funding Costs on the
Notes or imposed by reason of any failure to withhold with respect to such
payments.

          SECTION 7.03.  Calculation of Indemnity Payments.  If any Indemnitee
                         ---------------------------------                    
subsequently realizes a tax benefit by reason of any payment of an indemnified
Tax pursuant to this Article VII or by reason of payment of an amount, which
amount was reimbursed to such Indemnitee by Lessee on an After-Tax Basis
pursuant to a provision specifically requiring the payment of such amount on an
After-Tax Basis (other than pursuant to any provision of Article VI or the Tax
Indemnification Agreement, if any), which benefit had not previously been taken
into account in computing such payment, such Indemnitee shall pay Lessee when
such tax benefit is actually utilized (but not before Lessee shall have made all
payments and indemnification theretofore due to such Indemnitee pursuant to the
Operative Documents) an amount equal to the lesser of (a) the sum of (i) an
amount equal to such tax benefit, plus (ii) an amount equal to any other tax
benefit realized and actually utilized by such Indemnitee as the result of any
payment made by such Indemnitee pursuant to this sentence, and (b) the amount of
such payment and any other payment by Lessee to such Indemnitee with respect to
the Tax or other amount that gave rise to such tax benefit, reduced by other
amounts previously paid by such Indemnitee to Lessee with respect to the tax
benefits resulting from such Tax or other amount pursuant to this Article VII;
provided, however, that, notwithstanding the foregoing portions of this
- --------  -------                                                      
sentence, such Indemnitee shall not be obligated to make any payment to Lessee
pursuant to this sentence if and for so long as an Event of Default shall have
occurred and be continuing, but shall promptly make such payment once all Events
of Default shall no longer be continuing.  Any Taxes that are imposed on any
Indemnitee as a result of a disallowance or reduction of any tax benefit taken
into account in the prior sentence shall be treated as a Tax for which Lessee is
obligated to indemnify such Indemnitee pursuant to the provisions of Article VII
hereof without regard to Section 7.02 (other than subsections (c), (d), (e),
(f), (g), (h) and (i) thereof).

          SECTION 7.04.  Contest.  (a) If a claim shall be made against any
                         -------                                           
Indemnitee for any Tax in excess of $10,000 for which Lessee would be obligated
to indemnify pursuant to this Article VII, such Indemnitee shall promptly notify
Lessee after such Indemnitee becomes aware of such action and in any event
within 30 days after receipt by such Indemnitee of a written claim (but failure
to notify Lessee within such 30-day period shall not impair such Indemnitee's
right to indemnification under this 

                                      44
<PAGE>
 
Article VII except to the extent that Lessee's rights to contest such claim
shall have been materially impaired by such failure) and shall, to the extent
permitted by applicable law, not pay the claim before the earlier of (i) 30 days
after giving Lessee notice and (ii) receipt of Lessee's response. If Lessee
shall so request within the period referred to in the foregoing sentence, such
Indemnitee shall, at Lessee's expense reimbursed to such Indemnitee on an After-
Tax Basis, contest the imposition, validity or applicability of such Tax. The
ultimate control over the conduct of such contest (including the right to forgo
any and all administrative appeals, proceedings, hearings and conferences in
respect of such claim and the right to select the forum for such contest and
determine whether any such contest shall be by (i) resisting payment of such
Tax, (ii) paying such Tax under protest or (iii) paying such Tax and seeking a
refund thereof) shall remain with such Indemnitee; provided, however, that such
                                                   --------  -------       
Indemnitee shall keep Lessee or its counsel reasonably informed as to the
progress thereof, consult with Lessee within a reasonable period before any
significant action with respect thereto is taken or omitted and consider in good
faith any suggestions made by Lessee or its counsel; provided further that 
                                                     -------- -------      
unless (a) remedies under Section 16 of the Lease shall have been, or are being,
exercised in connection with an Event of Default which has occurred and is
continuing or (b) a Bankruptcy Default or Payment Default has occurred and is
continuing, and subject to Indemnitee's waiver rights described in Section
7.04(b) hereof, and provided that all conditions set forth in this Section 7.04
for the continuation of a contest shall then be satisfied, no such proceedings
or litigation shall be settled or otherwise compromised without the prior
written consent of Lessee. If such Indemnitee so elects, such contest shall be
conducted by Lessee in the name of such Indemnitee (subject to the preceding
proviso) and in no event shall such Indemnitee be required or Lessee be
permitted to contest or to continue to contest, as the case may be, the
imposition of any Tax for which Lessee is obligated to indemnify pursuant to
this Article VII unless (A) Lessee shall have agreed to pay such Indemnitee on
demand and shall have paid as so demanded all reasonable costs and expenses that
such Indemnitee may incur in connection with contesting such claim (including,
without limitation, all costs, expenses, losses, reasonable legal and accounting
fees and disbursements) on an After-Tax Basis, (B) Owner Participant shall have
determined in good faith that the action to be taken will not result in any
material risk of a Lien on, or of sale, forfeiture or loss of any Transponder or
any part thereof or any interest therein (except if Lessee shall have made
provision to protect the interests of Owner Participant in a manner satisfactory
to Owner Participant), (C) if such contest shall be conducted in a manner
requiring the payment of the claim, Lessee shall have advanced on an interest-
free basis an amount equal to the amount of such claim which such Indemnitee
shall have elected to pay and Lessee shall have indemnified the Indemnitee in a
manner satisfactory to the Indemnitee, for any adverse tax 

                                      45
<PAGE>
 
consequences from the receipt, or interest-free nature, of such advance and (D)
an Event of Default, Payment Default or Bankruptcy Default shall not have
occurred and be continuing unless Lessee has posted adequate security securing
payment of the Tax subject to the contest and expenses of the contest in a
manner reasonably acceptable to such Indemnitee.

          (b) An Indemnitee may at any time elect to settle or compromise any
proposed claim or contest or decline to take any action or any further action
with respect to a proposed claim or contest; provided, however, that if Lessee
                                             --------  ------- 
has properly requested such action pursuant to this Article VII and has
satisfied all conditions set forth in Section 7.04(a) for the continuation of a
contest, such Indemnitee shall notify Lessee that it waives its right to any
indemnity payment by Lessee that would otherwise be payable by Lessee pursuant
to this Article VII in respect of such claim. An election by an Indemnitee to
settle or compromise any proposed claim or contest or decline to take any action
or take any further action with respect to a proposed claim or contest for any
given taxable period shall not affect the rights and obligations of any other
Indemnitee with respect to such proposed claim. An election by an Indemnitee to
settle or compromise any proposed claim or contest or decline to take any action
with respect to a proposed claim or contest (under circumstances where Lessee
shall have properly requested action and satisfied all conditions for the
continuation of a contest set forth in Section 7.04(a)) shall not affect the
rights and obligations of such Indemnitee and Lessee hereunder in respect of any
other taxable period or any other taxing authority except to the extent such
election not to contest materially impairs as a legal or practical matter the
ability of Lessee or an Indemnitee to contest any Tax with respect to such other
taxable period or such other taxing authority for which such Indemnitee is
indemnified pursuant to this Article VII. Upon any such election by an
Indemnitee, if Lessee shall have advanced an amount to an Indemnitee pursuant to
clause (C) of Section 7.04(a), such Indemnitee shall repay the advance to
Lessee, plus interest on such advance from the date of the making of such
advance by Lessee to the day next preceding the day of repayment of such advance
by such Indemnitee calculated at the applicable rate of the tax authority with
respect to the claim to which the advance related; such repayment shall be made
upon the occurrence of the earlier of (x) final adjudication of such contest
(including a settlement thereof) and (y) such time as such Indemnitee shall
elect to discontinue the contest as above provided; provided, however, 
                                                    --------  -------  
notwithstanding the foregoing, such Indemnitee shall not be obligated to make
any repayment to Lessee pursuant to this sentence for so long as an Event of
Default shall have occurred and be continuing but shall promptly make such
payment once all Events of Default shall no longer be continuing.

          SECTION 7.05.  Reports.  If any report, return or statement is
                         -------                                        
required to be filed with respect to any Tax which 

                                      46
<PAGE>
 
is subject to indemnification under this Article VII, Lessee shall promptly
notify the appropriate Indemnitee of such requirement and shall timely file the
same, except for any such report, return or statement which an Indemnitee has
notified Lessee that such Indemnitee intends to file; provided, however, prior 
                                                      --------  -------        
to the filing by any Indemnitee of any report, return or statement in respect of
which an amount greater than $10,000 is required to be paid by Lessee, such
Indemnitee shall notify Lessee that such report, return or statement and such
Tax is due and such notification shall be within a reasonable amount of time to
enable Lessee to contest such Tax, and, with respect to any report, return or
statement being filed by Lessee, the Indemnitee shall at Lessee's expense be
required to provide Lessee on a timely basis with any information reasonably
requested, provided further, that, without prejudice to any other rights Lessee
           -------- -------                                                    
may have in connection therewith (including, without limitation, any claim for
damages for a failure to give the notice or reasonably requested information
pursuant to this Section 7.05), the failure to provide any such notice or
reasonably requested information shall not affect Lessee's obligations hereunder
to any Indemnitee unless such failure shall materially impair a contest of such
Tax.  Lessee shall either file such report, return or statement so as to show
the ownership of the Transponders in Owner Trustee and send a copy of such
report, return or statement to Owner Trustee or, where not so permitted,
promptly notify Owner Participant of such requirement and prepare and deliver
such report, return or statement to Owner Participant in a manner satisfactory
to Owner Participant within a reasonable time prior to the time such report,
return or statement is to be filed.

          SECTION 7.06.  Payment.  (a) Unless otherwise requested by the
                         -------                                        
appropriate Indemnitee, Lessee shall pay any Tax for which it is liable pursuant
to this Article VII directly to the appropriate taxing authority when due and,
if so otherwise requested, shall pay such appropriate Indemnitee within 15 days
after demand, in immediately available funds, any amount due such Indemnitee
pursuant to this Article VII with respect to such Tax or such payment, but not
prior to the later of (i) payment of such Tax and (ii) final adjudication
(including settlement consented to by Lessee) in the case of a contest pursuant
to Section 7.04.  Any such demand shall specify in reasonable detail the payment
and the facts upon which the right to payment is based.  Each Indemnitee shall
promptly forward to Lessee any notice, bill or advice received by it concerning
any Tax for which such Indemnitee claims indemnification hereunder.  Within 30
days after the date of each payment by Lessee of any Tax, Lessee shall furnish
the appropriate Indemnitee with the original or a certified copy of a receipt
for Lessee's payment of such Tax or such other evidence of payment of such Tax
as is acceptable to such Indemnitee.  Lessee shall also furnish promptly upon
request such data as any Indemnitee may require to enable such Indemnitee to
comply with the requirements of any taxing jurisdiction.

                                      47
<PAGE>
 
          (b) Lessee agrees that it shall have no right to inspect the books,
records, tax returns or any other document of such Indemnitee or any Affiliate
thereof in order to verify the basis or accuracy of the calculations made
pursuant to this Article VII; provided, however, within 10 days following
                              --------  -------                          
Lessee's receipt of any notice or demand involving calculations to be made
pursuant to this Article VII, Lessee may request that the correctness of such
calculations be verified (but such verification shall be limited to calculations
and shall not extend to any interpretation of the scope of any indemnity
provision or the existence of a liability hereunder), at Lessee's expense, by
one of the six largest United States public accounting firms selected by the
relevant Indemnitee and approved by Lessee, which approval will not be
unreasonably withheld, and such Indemnitee shall deliver to Lessee a certificate
of a senior officer together with a statement from such public accounting firm
confirming that the calculations set forth in or supporting the amount set forth
in such notice or demand to which such request relates have been verified as
above provided and that the calculations are accurate and in conformity with the
provisions of this Article VII. The assumptions, the method of calculation and
the other information revealed or made available to such accounting firm shall
be kept confidential and shall not be revealed by it to any other Person.

          SECTION 7.07.  Consolidated or Combined Return.  In the case of any
                         -------------------------------                     
Tax for which an Indemnitee claims indemnification hereunder that is reported on
a consolidated or combined basis by such Indemnitee, the rules applicable to the
consolidated or combined return of the Indemnitee shall be taken into account in
computing the amount of any indemnity or payment by or to Lessee under this
Article VII in respect of such Tax.

                                 ARTICLE VIII

                  Nature and Manner of Payment of Indemnities
                  -------------------------------------------

          SECTION 8.01.  Effect of Other Indemnities.  Lessee's obligations
                         ---------------------------                       
under the indemnities provided for in this Agreement shall be those of primary
obligor, whether or not the Person indemnified shall also be indemnified with
respect to the same matter under the terms of any of the other Operative
Documents, the Hughes Agreements or any other document or instrument, and the
Person seeking indemnification from Lessee pursuant to any provisions of this
Agreement may proceed directly against Lessee (subject to the provisions of this
Agreement) without first seeking to enforce any other rights of indemnification.

          SECTION 8.02.  Payments and Survival of Indemnities.  Unless otherwise
                         ------------------------------------                   
specifically provided for herein, all amounts payable by Lessee pursuant to
Articles VI and VII shall be payable directly to the Person entitled to payment
or indemnification.  Unless otherwise specifically provided herein 

                                      48
<PAGE>
 
or therein, the indemnities of the parties hereunder shall survive the
termination of this Agreement and the other Operative Documents and shall
survive the transfer of any Note or any interest of Owner Participant in
Lessor's Estate and the payment of any or all of the Notes.

          SECTION 8.03.  No Guarantees, etc.  Nothing herein or in the Tax
                         -------------------                              
Indemnification Agreement, if any, shall be construed as a guarantee by Lessee
of any residual or other value in the Transponders or the useful life of the
Transponders or constitute a guarantee by Lessee of payment of principal of or
interest on the Notes or any other amount payable under the Loan Agreement.

                                  ARTICLE IX

                         Payment of Transaction Costs
                         ----------------------------

          SECTION 9.01.  Transaction Costs.  (a) If the transactions
                         -----------------                          
contemplated by this Agreement to be consummated on the Commencement Date are
consummated, Owner Trustee shall as soon as practicable on or after the
Commencement Date(subject to paragraph (b) of this Section 9.01), pay when due,
or reimburse HCG upon request, for, all Transaction Costs not theretofore paid
by Owner Trustee with respect to the Transponders.  Owner Participant agrees to
provide to Owner Trustee funds to pay Transaction Costs payable by Owner Trustee
pursuant to the preceding sentence.  If the transactions contemplated by this
Agreement to be consummated on the Commencement Date are not consummated, HCG
shall pay when due all Transaction Costs accrued to such failed Commencement
Date, the payment of which is otherwise the obligation of Owner Trustee pursuant
to the first sentence of this Section 9.01(a); provided, however, that if such
                                               --------  -------              
transactions shall not be consummated by reason of a breach by Owner Trustee,
Owner Participant, Agent or any Loan Participant of its obligations hereunder or
under any other Operative Document or Hughes Agreement to which such Person is
or will be a party, or, if it shall have become a Defaulting Participant, Lessee
shall not be obligated to pay the Transaction Costs incurred by such Person.

          (b) To the extent any Transaction Costs, when combined with the other
amounts actually funded by Owner Participant pursuant to Sections 2.01(b)(i) and

Owner Participant shall transfer the Beneficial Interest free and clear of all
Owner Participant's Liens to Lessee pursuant to an instrument of conveyance in
form and substance reasonably satisfactory to Lessee; provided that Owner

Participant shall have been released from any obligations under the Operative
Documents arising after such purchase except to the extent that such obligations
are attributable to events or circumstances occurring prior to the purchase of
the Beneficial Interest by Lessee.

          (c) Each of Owner Participant, Owner Trustee, and Agent at the cost
and expense of Lessee and on an After-Tax Basis, will cause to be promptly and
duly taken, executed, acknowledged and delivered all such further acts,
documents and assurances as Lessee reasonably may request in order to carry out
the intent and purpose of this Article XI and the transactions contemplated
hereby.

          (d) It is a condition to Lessee's right to purchase the Beneficial
Interest pursuant to Section 11.02 that:

          (i) Owner Trustee, at Lessee's direction (and Owner Participant hereby
     agrees to join in the giving of such direction), will enter into a Loan
     Agreement Supplement with Agent, in form and substance reasonably
     satisfactory to Agent, for the purpose of deleting from the Loan Agreement
     the rights of Owner Participant and Owner Trustee set forth in Sections
     16.1, 16.2, 16.3, 16.4 and 16.5, in Section 13.1 (to the extent it provides
     for amendments or modifications to the Operative Documents or Hughes
     Agreements without Agent's consent) and in clause (vi) of Section 13.2 of
     the Loan Agreement;

               (ii) No Lease Event of Default shall have occurred and be
     continuing; and

               (iii)  Lessee shall pay the reasonable costs and expenses of
     Agent (including the reasonable fees and expenses of one counsel for Agent
     and the Loan Participants collectively) incurred in connection therewith.

          (e) As a condition to Lessee's right to purchase the Beneficial
Interest pursuant to Section 11.02 (unless there shall occur an Assumption with
respect to the obligations of Owner Trustee pursuant to the next sentence), on
the date of purchase Lessee shall have provided to Agent and Owner Trustee an
opinion of counsel for Lessee, dated the date of purchase, which, subject to
usual or customary exceptions, shall be to the effect that, upon consummation of
such purchase, this Agreement, the Trust Agreement, the Lease and, in the case
of Guarantor, the Guaranty

Agreement constitutes the legal, valid and binding obligation of Lessee or, in
the case of the Guaranty Agreement, Guarantor, enforceable against Lessee or
Guarantor, as applicable in accordance with its terms except as the same may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the rights of creditors generally and by general
principles of equity, and except as limited by applicable laws that may affect
the remedies provided for in the Lease, which laws, however, do not in the
opinion of such counsel make the remedies provided for in the Lease inadequate
for the practical realization of the rights and benefits provided for in the
Lease. In the event Lessee is unable to provide such opinion, concurrently with
the purchase of the Beneficial Interest Lessee shall Assume the obligations of
Owner Trustee under the Notes and under the Loan Agreement in accordance with,
subject to the conditions of and with the effect provided in Section 5.05(a)
hereof and Section 2.20 of the Loan Agreement, and upon such Assumption, Lessee
shall have the right to terminate the Trust Agreement.

          (f) Owner Trustee and Lessee acknowledge and agree that the former
Owner Participant which shall have transferred the Beneficial Interest to Lessee
pursuant to this Section 11.02 (the "Transferor") is entitled to all Rent which
                                     ----------                                
by its terms is payable in arrears accrued to and including, or attributable to
events or circumstances occurring prior to, the date of purchase pursuant to
this Section 11.02. Owner Trustee hereby agrees that upon receipt by it of any
amounts in respect of such Rent, it will forthwith pay over such amounts to the
Transferor.

          (g)  From and after any purchase of the Beneficial Interest pursuant
to this Section 11.02, (i) the Transferor shall be released from its liability
hereunder and under the other Operative Documents to which it is or will be a
party in respect of obligations to be performed after such purchase (but not
obligations that should have been performed, but were not so performed, on or
prior to such purchase) and (ii) Lessee shall be deemed "Owner Participant" for
all purposes of the Operative Documents and each reference herein to Owner
Participant shall thereafter be deemed a reference to Lessee for all purposes.

clause (i) of Section 11.02(a)) or HCG (in the case of clause ii) of Section
11.02(a)) shall irrevocably notify Owner Trustee, Owner Participant and Agent in
writing thereof (i) at the same time Lessee provides irrevocable notice to
Lessor under Section 19(b) or 19(c) of the Lease or (ii) on the date that would
have been the Commencement Date with respect to Section 10.01.

Notes and, to the extent available, expenses in connection with such refunding.
Subject to the limitations set forth in Section 12.02, the amortization schedule

Notes.  As a condition to such refunding, Lessee will be liable for, and shall
pay, on an After-Tax Basis, the reasonable out-of-pocket expenses incurred by
Owner Trustee, Agent, each Loan Participant and Owner Participant in connection
with such refunding (whether or not such refunding shall be consummated, so long
as the failure to consummate such refunding does not result solely from a
default by Owner Participant in its obligations hereunder); provided that Lessee

amendments to or consents or waivers under each of the Operative Documents as
may be reasonably requested by Lessee to effect the transactions contemplated in
connection with any such refunding, subject, however, to the following
conditions:

           (i) the refunding results in payment in full to the holder or holders
     of the Refunded Notes of the unpaid principal amount of, and accrued and
     unpaid interest on, such Refunded Notes (together with any Break Funding
     Costs) held by such holder or holders, and of all other amounts then due
     and owing by Lessee to such holder or holders pursuant to any other

<PAGE>
 
          (ii) no Bankruptcy Default or Event of Default shall have occurred 
     and be continuing as of the date of such refunding, and the refunding shall
     occur on a Rent Payment Date;

         (iii) the terms and conditions of such refinancing shall, pursuant to
     an adjustment to the Factors as provided in and in accordance with Sections
     13.01, 13.02, 13.03 and 13.04, in each case as applicable, preserve Owner
     Participant's Net Economic Return as therein provided;

     (i) such opinions of counsel as they may reasonably request concerning
     compliance with the Securities Act and any other Applicable Law relating to
     the sale of securities and (ii) such other opinions of counsel and such
     certificates and other documents, each in form and substance reasonably
     satisfactory to each of them, as they may reasonably request in connection
     with compliance with the terms and conditions of this Article XII;

           (v) all necessary authorizations, approval and consents shall have
     been obtained;

          (vi) if required by Owner Participant, Owner Participant shall have
     received from tax counsel, an opinion to the effect that Owner Participant
     is not incurring additional income tax risk as a result of the terms and
     provisions, as opposed to the existence of, such refinancing or, in lieu of
     such tax opinion, and provided that there is, in the opinion of tax
     counsel, a reasonable basis for taking the reporting position requested by
     Lessee, an indemnity reasonably satisfactory to Owner Participant from
     Lessee with respect to any such additional income tax risk; and

         (vii) the terms and conditions of such Refunding Notes (excluding the
     economic terms thereof) will, in the aggregate, be no less favorable to

and, as necessary, Agent, shall consult thereafter on the negotiation of such

agreed among the parties thereto in due course thereafter.  Lessee will provide

or to cause Owner Trustee to take, any action in connection therewith other than
such as may be requested by Lessee as provided in this Article XII.

the Factors, as set forth in Exhibit A to the Commitment Letter, to be made on
the Commencement Date.  On the Commencement Date, the Owner Participant shall
adjust Scheduled Rent, Termination Values, Stipulated  Loss Values, the EBO
Amount and, if requested by Lessee, the EBO Date to reflect (a) any changes made
by the Commencement Date Appraisal to the Closing Date Appraisal, and (b)
without duplication of clause (a), discrepancies between the applicable Pricing
Assumption set forth on Annex 1 to Exhibit A to the Commitment Letter and (i)
the actual Commencement Date, (ii) the actual interest rate borne by the Notes
(or in the event the Notes are floating rate notes, the Assumed Interest Rate
that would be applicable to the Notes if the Notes were fixed rate notes) and
the actual principal amount of the Notes and Debt Amortization Schedule for the
Notes (exclusive of any balloon payment if the maturity date of the Notes occurs
prior to the end of the Basic Term), (iii) the actual length of the Lease Term
(exclusive of any Renewal Term) and (iv) the anticipated amount and timing of
payment of Transaction Costs.

          Such adjustment will be made in a manner which shall preserve Owner
Participant's Net Economic Return inherent in Exhibit A to the Commitment Letter
and in such a way as to minimize, in a manner reasonably satisfactory to HCG,
the present value (discounted to the Commencement Date using the Discount Rate)
of (x) Scheduled Rent up to and inclusive of the EBO Date and the EBO Amount
(excluding any portion of Scheduled Rent deemed to be "advance rent" on the EBO

of the Factors set forth in Exhibit A to the Commitment Letter. The Debt
Amortization Schedule shall be allowed to vary only as directed by Lessee. The
Factors resulting from and the Pricing Assumptions used in any recalculation of
Factors pursuant to this Section 13.01 shall amend Exhibit A to the Commitment
Letter and be attached hereto as Schedule IV.

- -----------------                                                           
adjustments to the Factors, as set forth in Schedule IV as in effect on the
Commencement Date, to be made after the Commencement Date.

          The Factors shall be adjusted by Owner Participant in accordance with
the following provisions of this Section 13.02, to take into account (i) the
actual amount and timing of payment of Transaction Costs, if other than as set
forth in Schedule IV, as amended, (ii) the actual Deferred Equity Amount or the
timing of payment thereof, if other than as set forth in Schedule IV, as
amended, and (iii) any refinancing of the Notes provided for in this Agreement.
Such adjustment will be made in a manner which shall preserve Owner
Participant's Net Economic Return and in such a way as to satisfy the PV
Minimization Requirement.  Upon the request of Lessee, the Factors shall be
adjusted as of the Basic Term Commencement Date to take into account any
adjustments required by clause (i) or (ii) that have not previously been taken
into account by any adjustment to the Factors pursuant to this Section 13.02.

          Any adjustment pursuant to Section 13.02 shall be made in the same
manner, and shall employ the same (A) OP Methodology, and (B) assumptions
including, without limitation, each of the Pricing Assumptions set forth in
Schedule IV, except as such Pricing Assumptions shall have been modified by the
event giving rise to such adjustment or by previous adjustments under this
Section 13.02, in each case as was made and as was employed in the calculation
of the Factors set forth in Schedule IV as in effect prior to the making of such
adjustment.  In making any adjustment to the Factors under this Section 13.02,
the Debt Amortization Schedule shall be allowed to vary as permitted by

Section 13.04, subject to any restrictions as may be set forth in the Loan
Agreement and as directed by Lessee.

          SECTION 13.03.  Confirmation of Adjustments; Further Assurances.  (a)
                          -----------------------------------------------      
The adjustment to any of the Factors pursuant to Section 13.01 or 13.02 shall be
determined by Owner Participant.  Owner Participant shall provide to Lessee and
Lessor, notice of such adjustment accompanied by an Officer's Certificate of
Owner Participant, which Officer's Certificate shall set forth such adjustment
and which shall confirm that such adjustment was made in accordance with the
provisions of Section 13.01 or 13.02, as applicable, and Section 13.04. Such
adjustment shall, subject to the following provisions of this Section 13.03,
become effective not later than the Commencement Date, or if such adjustment
occurs after the Commencement Date, on the next succeeding Rent Payment Date
which occurs at least 15 days after the date of such adjustment, or, if later,
the date of the conclusion of the verification procedure set forth in Section
13.03(b) (in each case taking into effect the effective date of such
adjustment).

          (b) Within five Business Days after receipt of an Officer's
Certificate pursuant to paragraph (a) above in respect of an adjustment pursuant
to Section 13.01 or within 20 Business Days after receipt of an Officer's
Certificate pursuant to paragraph (a) above in respect of an adjustment pursuant
to Section 13.02, if Lessee believes that such adjustment is incorrect, Lessee
may request that such adjustment be verified by one of the six largest U.S.
independent public accounting firms, including Owner Participant's regular
independent accounting firm, as selected by Owner Participant.  In such
verification process, such accounting firm shall be given access by Owner
Participant to the assumptions, methods of calculation, computations, computer
programs and files employed by Owner Participant in calculating such proposed
adjustment and employed in the original calculation of the Factors, subject to
the execution of such confidentiality agreements as Owner Participant shall
reasonably request.

          Such verification by such accounting firm shall be at the expense of
Lessee unless such verified adjustment results in a readjustment in favor of
Lessee that exceeds five basis points in the PV EBO, in which case verification
shall be at the expense of Owner Participant.  Such determination of the
adjustment by Owner Participant, or, if so requested in accordance with this
Section 13.03(b), such verified adjustment, as the case may be, shall be
conclusive and binding on the parties hereto.  Owner Participant will not be
liable for verification expenses if the cause of the readjustment that would
otherwise give rise to the liability is the employment of an optimizing
technique which is not known by Owner Participant as of the date of such
readjustment.

          (c) At the time any adjustment is made pursuant to Section 13.01 or
13.02 or this Section 13.03, the parties hereto shall memorialize such
adjustment as appropriate and shall enter into such amendments to the Operative
Documents (including an amendment to Schedule IV, as then amended, to this
Agreement and a supplement to the Lease) and do such further acts as may be
reasonably required in order to effectuate such adjustment; provided that such
                                                            --------          
adjustment shall become effective as provided in this Section 13.03 without
regard to the date on which any such document is executed and delivered; and
                                                                            
further provided that any amendment to Schedule IV pursuant to Section 13.01,
- ------- --------         
13.02 or 13.03 may be made by Owner Participant and Lessee.

          SECTION 13.04.  Compliance with Code.  (a) All Rental Adjustments
                          --------------------                             
under Section 13.01 or 13.02 will comply with Sections 4.07(l), 4.07(2) and 4.08
of Rev. Proc. 75-28 and Section 467 of the Code (provided Section 4.08 of Rev.
Proc. 75-28 and Section 467 of the Code will be applied on a prospective basis
from the date of such adjustment).

          (b)  In connection with any recalculation of the Factors pursuant to
Section 13.01 or 13.02, if Lessee so requests, the principal amount of, and Debt
Amortization Schedule for, the Notes then outstanding may be changed, provided
that the Owner Participant's Net Economic Return is maintained in accordance
with Section 13.01 or 13.02, as applicable.

          (c)  In connection with any recalculation of the Factors pursuant to
Section 13.01 or 13.02, if Lessee so requests, the EBO Date may be changed,
provided that the Owner Participant's Net Economic Return is maintained in
accordance with Section 13.01 or 13.02, as applicable.  Owner Participant shall
have the right to consent to any change in the EBO Date that differs by more
than one year.

     shall violate any provision of, or create a relationship which would be in
     violation of, any Applicable Laws, including, without limitation,
     applicable securities laws, any agreement to which Owner Participant or the
     Transferee is a party or by which it or any of its property is bound and
     such transfer to or ownership by such Transferee will not result in a

effected in accordance with this Article XIV, the Person making such transfer
(and any Person guaranteeing the obligations of such transferor) shall be
released, to the extent of the 

                                      62
<PAGE>
 
obligations assumed by the Transferee (and, if required hereunder, guaranteed by
an Affiliate of such Transferee), from their respective liabilities hereunder
and under the other Operative Documents to which either of them is a party in
respect of obligations to be performed on or after the date of such transfer.
Upon any transfer by Owner Participant in accordance with this Article XIV, the
Transferee shall be deemed "Owner Participant" for all purposes of the Operative
Documents (unless otherwise specifically set forth herein) and each reference
herein to Owner Participant making such transfer shall thereafter be deemed a
reference to such Transferee for all purposes, except as provided in the
preceding sentence.

extent reasonably so requested by Owner Participant and at the expense of Owner
Participant (except to the extent Lessee is obligated to pay such expenses under
other provisions of the Operative Documents, subject to the provisions of
Sections 6.02(e) and 6.02(g), which shall prevail), use good faith efforts to
assist Owner Participant in effecting any transfer of its interest in the

part of the Lessor's Estate becomes the property of, or the Owner Participant
becomes, a debtor subject to the reorganization provisions of the Bankruptcy
Reform Act of 1978 or any successor provision, (ii) pursuant to such
reorganization provisions the Trust Company (in its individual capacity) or the
Owner Participant is required, by reason of the Trust Company (in its individual
capacity) or the Owner Participant being held to have recourse liability to the
holder(s) of the Notes or to the Agent, directly or indirectly, to make payment
on account of the principal of or interest on the Notes and (iii) any holder of
a Note or the Agent actually receives any Excess Payment (as hereinafter
defined) which reflects any payment by the Trust Company (in its individual
capacity) or the Owner Participant on account of clause (ii) above, then such
holder of a Note or the Agent, as the case may be, shall promptly refund to the
Trust Company or the Owner Participant (whichever shall have made such payment)
such Excess Payment.  For purposes of this Section 14.04, "Excess Payment" means
the amount by which such payment exceeds the amount which would have been
received by the holder(s) of the Notes or the Agent if the Trust Company (in its
individual capacity) or the Owner Participant had not become subject to the
recourse liability referred to in clause (ii) above.  Nothing contained in this
Section 14.04, shall prevent any holder of a Note or the Agent from enforcing as
a full recourse obligation (and retaining the proceeds thereof) any obligation
under this Agreement or any other Operative Document that is expressed as being
an obligation of the Owner Participant.

by Lessee with an appropriate legend, marking, stamp or other obvious written
identification prior to disclosure.  In the event that Lessee discloses its
Proprietary Information to Recipient other than in the manner provided for in
this paragraph (b), then Lessee shall promptly inform Recipient that such
information is deemed proprietary and shall provide Recipient with a brief
written description of such information within thirty (30) days of such
disclosure, identifying therein the manner, place, and date of such disclosure
and the names of Recipient's representatives to whom such disclosure was made

Proprietary Information.  Proprietary Information shall also mean any
information, whether in written form or not, prepared by Recipient or anyone
receiving Proprietary Information from Recipient or incorporating Proprietary
Information.

          (c) Recipient shall not use the Proprietary Information, except in

the event of such requested destruction, Recipient shall provide to HCG or
Lessee, as applicable, written certification of compliance therewith within
thirty (30) days of such written request.

          (e) The disclosure of Proprietary Information under this Section 16.01
shall not be construed as granting either a license under any patent, patent
application, or copyright, or any right of ownership in said Proprietary
Information, nor shall such disclosure constitute any representation, warranty,
assurance, guarantee, or inducement by Lessee with respect to infringement of
patents or other rights of others.

Person to be bound by the terms of this Section 16.01, in which case Recipient
shall not be liable for any breach by such Person of the terms thereof.  By way
of illustration only and not by way of limitation, the provisions of this

responsible for any consequential or incidental damages or for Lessee's

construed as creating any liability of Trust Company, individually or
personally, to perform any covenant, expressed or implied, contained herein, or
for the payment of any indebtedness or expense of the trust created by the Trust

parties hereto, and by any Person claiming by, through or under them.

right, power and remedy whether specifically given herein or under any other
Operative Document or Hughes Agreement or otherwise existing may be exercised
from time to time and as often and in such order as may be deemed expedient by

construed to be a waiver of any other right, power or remedy.  No delay or
omission by any party in the exercise of any right, power or remedy or in the
pursuit of any remedy shall impair any such right, power or remedy or be
construed to be a waiver of any default or to be an acquiescence therein.  No

     ------
     Lessor Interim Amount not paid by Lessor.  Lessor shall give notice to
     Lessee and Agent at least five Business Days prior to such interest payment
     date if funds equal to the Lessor Interim Amount will not be paid by Lessor
     on such date, provided, however, that Lessor's failure to deliver such

     Notes becomes due and payable during the Basic Term on a date other than on
     a Rent Payment Date, Lessee shall pay to Lessor, on such date, Base Rent in
     an amount equal to the amount of such interest.

     any Transponder for the period that such Transponder is subject to this
     Lease.

               (iii) As Supplemental Rent, Lessee shall pay, when due, on behalf
     of Lessor, to Agent, for its own account or for the account of the

hereafter designate in writing) for so long as the Lien of the Loan Agreement
shall remain in effect and thereafter to Lessor.  All Supplemental Rent

time, at the place of payment as designated in Section 3(i) hereof), on the
scheduled date on which such payment shall be due, unless such scheduled date
shall not be a Business Day, in which case such payment shall be due and payable
on the immediately succeeding Business Day with the same force and effect as if
made on such scheduled date, and (provided such payment is made on such next
succeeding Business Day) no interest shall accrue on the amount of such payment
from and after such scheduled date.

          (e) Late Payment.  If any Rent shall not be paid when due, Lessee
              ------------                                                 
shall pay to Lessor or to Agent, as the case may be (or, in the case of
Supplemental Rent, to any Person entitled thereto as provided herein or in any
other Operative Document or Hughes Agreement), as Supplemental Rent, interest
(to the extent permitted by law) on such overdue amount from and including the
due date thereof to but excluding the date of payment thereof (unless payment is
made after 1:00 p.m. (local time, at the place of payment as designated in
Section 3(i) hereof), in which event such date of payment shall be included) at

sufficient to make all payments of scheduled principal, if any, and accrued
interest due and payable on such day (or the next Business Day, if such day is
not a Business Day) on the Notes then outstanding in respect of such Transponder
and (2) for any Transponder, the amount of Stipulated Loss Value, Termination

Participation Agreement, as applicable, together with Base Rent payable under
this Lease on any day specified in this Lease (or Schedule thereto) for the

an amount sufficient to make all payments of principal and accrued interest
which would be due and payable on such day (or the next Business Day, if such
day is not a Business Day) on the Notes then outstanding in respect of such
Transponder, assuming such day or the EBO Date, as the case may be, was the date

mentioned above, or by any court; (8) any claim that Lessee or Guarantor has or
might have against any Person, including, without limitation, Agent, any
Noteholder, Lessor or Owner Participant (but this Section 3(g) shall not
constitute a waiver of any such claims); (9) any failure on the part of Lessor,

Document or Hughes Agreement, or any waiver or other action or inaction under or
in respect of any Operative Document or Hughes Agreement, or any exercise or
nonexercise of any right or remedy under or in respect of any Operative Document
or Hughes Agreement, including, without limitation, any foreclosure or other
remedy under the Loan Agreement or this Lease or the sale, pursuant to any such
foreclosure or such exercise of other remedy, of any Transponder or any portion
thereof or interest therein; or (14) any other occurrence whatsoever, whether
similar or dissimilar to the foregoing, whether or not Lessee shall have notice
or knowledge of any of the foregoing.  Except as expressly provided herein,
Lessee, to the extent permitted by law, waives all rights now or hereafter
conferred by statute or otherwise to quit, terminate or surrender this Lease, or
to any diminution or reduction of Rent payable by Lessee hereunder.  If this
Lease shall be terminated in whole or in part for any reason whatsoever except
as expressly provided in this Lease, Lessee shall nonetheless pay to Lessor (or,
in the case of Supplemental Rent, to Lessor for its own account or to any Person
entitled to such Supplemental Rent as specified herein or in the appropriate
Operative Document or the Hughes Agreement), an amount equal to each Rent
payment at the time and in the manner that such payment would have become due
and payable under the terms of this Lease if it had not been terminated in whole
or in part.  Except with respect to payment of any Advance Amount and as
otherwise provided in Section 3(h) hereof, each payment of Rent shall be final,
and Lessee agrees not to seek to recover all or any part of any such payment
from Lessor, Agent or Owner Participant for any reason under any circumstance
whatsoever; provided, however, that nothing contained in this Section 3(g) shall
            --------  -------                                                   
prevent Lessee from bringing an action for damages suffered by Lessee as a
result of the breach by any Person of any obligation of such Person expressly
stated in any Operative Document or Hughes Agreement or for equitable relief to
obtain compliance with any such obligation, or for the return of mistakenly paid
amounts of any Rent or from exercising the rights set forth in Section 3(h)
hereof. Nothing contained in this Section 3(g) shall be construed as: (1) a
guaranty of (i) the value of the Transponders upon termination of the Basic Term
or any Renewal Term or (ii) the useful life of the Transponders or (iii) payment
of any of the Notes; or (2) a prohibition of assertion of any claim against any
manufacturer, supplier, dealer, vendor, contractor, subcontractor or installer
with respect to the Transponders; or (3) a waiver by Lessee of its right to
assert and sue upon any claims it may have against any other Person in one or
more separate actions.

          (h) Repayment of Advance Amount.  Lessee shall be repaid, in the
              ---------------------------                                 
manner provided in the next sentence, any amounts constituting Advance Amount
(which shall mean any portion of the Deferred Equity Amount advanced by Lessee
pursuant to Section 3(b)(i) hereof (excluding any portion thereof required to be
paid by Lessee pursuant to Section 2.07(b) of the Participation Agreement) plus
interest thereon at a simple interest rate of 14% per annum from the date that
any portion of such Deferred Equity Amount is advanced by Lessee to but not
including the date such amounts are repaid by Lessor).  In order to effect a
repayment of the Advance Amount, Lessee shall be entitled to offsets (without
duplication) against any payments of Rent (other than as limited by the three
provisos to this sentence) due from Lessee to Lessor (including, without
limitation, Base Rent, Supplemental Rent, Stipulated Loss Value, Termination
Value or the EBO Amount and all other amounts payable to Lessor

in connection with any termination of this Lease, but excluding Excepted
Payments payable to the Trust Company) until Lessee has received the full amount
of the Advance Amount, whether by cash payment, offsets as herein provided, or
any combination thereof; provided, however, that, in case of any payment due to
                         --------  -------                                     
Lessor from Lessee, Lessee's right of offset shall be limited to the portion of
such payment, if any, distributable to Lessor under the Loan Agreement; provided
                                                                        --------

offsets shall reduce the amount of any installment of Base Rent, amounts due
under Section 3(b)(i), Stipulated Loss Value, Termination Value or the EBO
Amount as of any date payable under this Lease to an amount that would be in
contravention of the minimum payment requirements of Section 3(f) or reduce the
amount of any Break Funding Costs that may be payable to the Noteholders; and
provided further, however, that Lessee shall have no right of offset so long as
- -------- -------  -------                                                      
any Payment Default, Bankruptcy Default or Event of Default has occurred and is
continuing.

          (i) Place of Payment.  All Rent (other than Rent payable to Persons
              ----------------                                               
other than Lessor as provided in any of the Operative Documents or Hughes
Agreements, which shall be payable to such other Persons in accordance with
written instructions furnished to Lessee by such Persons) shall, subject to
Section 3(d) hereof, be paid by Lessee to Lessor to its account specified in
Item 6 to Schedule E hereto, or such other account as Lessor may hereafter

designate in writing.  All Rent shall be paid by Lessee by wire transfer of
immediately available funds in Dollars.

       SECTION 5.  Representations, Warranties and Agreements as to the
       ----------  ----------------------------------------------------
Transponders.
- ------------ 

          (a) Disclaimer of Warranties.  AS BETWEEN LESSEE AND LESSOR, THE
              ------------------------                                    
DEEMED DELIVERY AND ACCEPTANCE OF EACH TRANSPONDER BY LESSOR AND LESSEE,
RESPECTIVELY, PURSUANT TO SECTION 2 SHALL BE CONCLUSIVE PROOF OF SUCH
TRANSPONDER'S COMPLIANCE WITH ALL REQUIREMENTS OF THIS LEASE, AND LESSOR LEASES
AND LESSEE TAKES SUCH TRANSPONDER AND ANY PART THEREOF AS IS, WHERE IS, WITH ALL
FAULTS, AND LESSEE ACKNOWLEDGES THAT NONE OF LESSOR, THE TRUST COMPANY, OWNER
PARTICIPANT, ANY NOTEHOLDER AND AGENT HAS MADE, NOR SHALL BE DEEMED TO HAVE
MADE, ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE TITLE,
VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION, MERCHANTABILITY, DESIGN,
QUALITY, DURABILITY, OPERATION OR FITNESS FOR USE OR PURPOSE OF SUCH TRANSPONDER
OR ANY PART THEREOF, AS TO THE ABSENCE OF ANY INFRINGEMENT OF ANY PATENT,
TRADEMARK OR COPYRIGHT, OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER,
EXPRESS OR IMPLIED, WITH RESPECT TO SUCH TRANSPONDER OR ANY PART THEREOF OR
OTHERWISE, IT BEING AGREED THAT ALL RISKS INCIDENT THERETO ARE TO BE BORNE BY
LESSEE IN THE EVENT OF ANY DEFECT OR DEFICIENCY IN SUCH TRANSPONDER OR ANY PART
THEREOF, OF ANY NATURE WHETHER PATENT OR LATENT, AND THAT NONE OF LESSOR, THE
TRUST COMPANY, OWNER PARTICIPANT, ANY NOTEHOLDER AND AGENT SHALL HAVE ANY
RESPONSIBILITY OR LIABILITY WITH RESPECT THERETO, except that Lessor hereby
represents, warrants and covenants that (A) on the Commencement Date, Lessor
shall have

                                       6
<PAGE>
 
whatever title to such Transponder, subject to Permitted Liens (other than those
referred to in clause (b) of the definition thereof), that was conveyed to it by
Owner Participant under the GMAC Bill of Sale on the Commencement Date, and (B)
during the Lease Term (so long as no Event of Default shall have occurred and be
continuing) Lessor will not, through its own actions or inactions, interfere
with the quiet enjoyment of any Transponder by Lessee and Lessor further agrees
that it will not directly or indirectly create, incur, assume or suffer to exist
any Lessor Lien on or with respect to any Transponder.  The provisions of this
Section 5(a) have been negotiated, and except as expressly provided in the
Operative Documents, the foregoing provisions are intended to be a complete
exclusion and negation of any warranties by Lessor, the Trust Company, Owner
Participant, any Noteholder and Agent, express or implied, with respect to such
Transponder, whether arising pursuant to the Uniform Commercial Code or any
other law now or hereafter in effect, or otherwise.  Nothing contained herein
shall in any way diminish or otherwise affect any right Lessee may have with
respect to any Transponder against any other third person.  None of Lessor, the
Trust Company, Owner Participant, any Noteholder and Agent shall at any time be
required to inspect such Transponder, nor shall any inspection by Owner
Participant, Lessor, the Trust Company, any Noteholder or Agent be deemed to
affect or modify the provisions of this Section 5(a).

          (b) Exercise of Certain Rights under the Hughes Agreements.
              ------------------------------------------------------ 

               (i) HCG, in its capacity as Seller under the Bill of Sale and the
     Purchase Agreement, is making certain representations and warranties and
     undertaking certain payment obligations to Lessor in its capacity as Buyer
     under the Purchase Agreement and as assignee of the Bill of Sale with
     respect to the Transponders.  None of the provisions of the Bill of Sale or
     the Purchase Agreement is, as such, incorporated in this Lease and LESSOR
     ACKNOWLEDGES THAT LESSEE, IN ITS CAPACITY AS LESSEE, HAS NOT MADE NOR SHALL
     BE DEEMED TO HAVE MADE ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED,
     WITH RESPECT TO ANY TRANSPONDER, OR ANY PART THEREOF, IN THIS LEASE, THE
     BILL OF SALE OR ANY OF THE OTHER OPERATIVE DOCUMENTS, INCLUDING, WITHOUT
     LIMITATION, AS TO THE TITLE, VALUE, COMPLIANCE WITH SPECIFICATIONS,
     CONDITION, DESIGN, QUALITY, DURABILITY, OPERATION, MERCHANTABILITY OR
     FITNESS FOR USE OR PURPOSE OF SUCH TRANSPONDER, AS TO THE ABSENCE OF LATENT
     OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO THE ABSENCE OF ANY
     INFRINGEMENT OF ANY PATENT, TRADEMARK OR COPYRIGHT, OR ANY OTHER
     REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO
     SUCH TRANSPONDER OR ANY PART THEREOF, EXCEPT AS OTHERWISE SPECIFICALLY
     PROVIDED IN THE OPERATIVE DOCUMENTS.  The foregoing is not in any way
     intended to, nor shall it be deemed to, limit or otherwise affect the
     obligations or representations or warranties of HCG under Section 4.01 of
     the Participation Agreement or Lessee under Article VI of the Participation
     Agreement, of Seller under the Purchase Agreement or of Contractor under
     the Service Agreement.

               (ii) Lessor hereby agrees that so long as no Event of Default
     shall have occurred and be continuing with respect to a Transponder, Lessor
     shall not exercise, during the Lease Term for such Transponder, any of its
     rights under the Hughes Agreements in respect of such Transponder,
     including any of its rights to any indemnity or other payments with respect
     to such Transponder; provided that Lessee cannot waive the obligations of
                          --------                                            
     Seller or Contractor,

                                       7
<PAGE>
 
     and Lessor may exercise any rights and remedies it might have, under
     Sections 5.1, 5.3, 5.5, 8.1, 14.2, 15.10, 15.12 and the last sentence of
     15.16 of the Purchase Agreement and under Article 7 and Sections 2.1(b),
     4.1, 4.2, 4.5, 4.7, 6.3, 6.4, 12.10 and 12.12 of the Service Agreement;
     provided, in addition that, notwithstanding anything to the contrary in the
     --------  -- --------                                                      
     foregoing, Lessor shall, at all times, retain the right to defend its title
     to the Transponders and to enforce its rights under the Lease or the
     Purchase Agreement or the Participation Agreement to cause Lessee or Seller
     or Owner Participant, as applicable, to defend such title in accordance
     with the provisions hereof or thereof.  Lessee may consent to the
     preemption or interruption of any Transponder by Seller under Section 7.1
     of the Purchase Agreement, without regard to the Transponder Priority List
     set forth in Appendix E thereto, and such preemption or interruption shall
     not constitute a Confirmed Failure (if it would otherwise constitute a
     Confirmed Failure) only if: (a) such preemption or interruption will not
     adversely affect the ability (1) of Lessee to meet its obligations under
     this Lease or any of the Operative Documents or Hughes Agreements to which
     it is a party or (2) of such preempted or interrupted Transponder to meet
     the Transponder Performance Specifications upon the cessation of such
     preemption or interruption or  otherwise cause an Adverse Effect to
     Lessor's (or to Owner Participant's) interest in such Transponder upon the
     expiration or termination of the Lease; (b) at the time such preemption or
     interruption ceases, such Transponder meets the applicable Transponder
     Performance Specifications; and (c) Lessee (and Seller, if the two parties
     shall be different entities) shall deliver to Lessor an Officer's
     Certificate (or Officer's Certificates, if applicable) prior to such
     preemption or interruption confirming (A) the statement set forth in clause
     (a) above and (B) that, based on information available to Lessee at such
     time, Lessee reasonably believes that the Transponder will be capable of
     meeting the Transponder Performance Specifications therefor upon cessation
     of such preemption or interruption.  At such time as any of the foregoing
     conditions is not met, then the Confirmed Failure of such Transponder
     shall, if the other conditions for a Confirmed Failure are met, be deemed
     then to have occurred. Lessor hereby authorizes Lessee, for so long as this
     Lease shall be in effect with respect to any Transponder and so long as no
     Event of Default shall have occurred and be continuing, to exercise in the
     name of and on behalf of Lessor, the right and power to deal with the
     Seller and Hughes Services under the Hughes Agreements and any other
     manufacturer or supplier of such Transponder or any other users of the
     transponders on the Satellite including, without limitation, the right to
     demand, receive, accept and retain all services, tests, inspection rights,
     reports and other data and services with respect to such Transponder as
     provided in the Purchase Agreement and the Service Agreement, and the right
     to enforce (by legal action or otherwise) or to elect not to enforce
     (except in such manner as would have a material adverse effect on Lessor's
     interest in the Transponders upon expiration or termination of the Lease)
     against such Seller, Hughes Services, other manufacturer or supplier or
     other user all rights, powers and privileges of Lessor, and to receive all
     benefits (subject to Sections 12(b), 12(c) and 12(d) of Lessor with respect
     to Seller, Hughes Services, such other manufacturer or such supplier or
     such other user, under any express or implied warranty or indemnity or
     other provisions of the Hughes Agreements or substitute agreements in
     effect, pursuant to Section 7(b) or otherwise, including, without
     limitation, the right to enforce (or not enforce (except in such manner as
     would have a material adverse effect on Lessor's interest in the
     Transponders upon the expiration or termination of the Lease)) and the
     right to obtain and retain the benefits of, all rights and claims of Buyer
     under the Purchase Agreement or of Owner under the Service Agreement;
     provided that, notwithstanding any term or provision of this Section
     --------                                                            
     5(b)(ii) to the contrary, Lessor and Owner Participant shall retain the
     right to any Excepted Payment owing to either of them, respectively.

                                       8
<PAGE>
 
          (iii)  If, notwithstanding the foregoing, Lessor receives any payment
     of any kind whatsoever under the Purchase Agreement or the Service
     Agreement during the Lease Term to which Lessee is entitled pursuant to
     Section 5(b)(ii), Lessor shall upon receipt remit to Lessee the full amount
     of the payment received by it under the Purchase Agreement, or the Service
     Agreement, as the case may be; provided that no Payment Default, Bankruptcy
     Default or Event of Default shall have occurred and be continuing; provided
                                                                        --------
     further, however, that Lessor shall promptly remit such amounts to Lessee
     -------  -------                                                         
     at such time as no Payment Default, Bankruptcy Default or Event of Default
     is continuing.

     SECTION 6.  Liens; Quiet Enjoyment; Assignment and Sublease.
                 ----------------------------------------------- 

          (a) Liens.  Lessee shall not directly or indirectly create, incur,

assume or suffer to exist any Lien on or with respect to any Transponder, the
Lessor's Estate or the Collateral Security, or title thereto or any interest
therein, except Permitted Liens.  Lessee's obligations under this Section 6(a)
with respect to any Lien, other than Owner Participant Liens or Lessor Liens, on
any Transponder arising prior to the termination of this Lease shall survive
such termination.

          (b) Quiet Enjoyment.  So long as no Event of Default shall have
              ---------------                                            
occurred and be continuing, as between Lessee and Lessor, Lessee shall have the
exclusive rights to possession and control of each Transponder and Lessor shall
not take any action that interferes with the quiet enjoyment of the use or non-
use of any Transponder by Lessee, and Lessee shall have the right to use or not
use such Transponder in its sole discretion.

          (c) Use Agreements.  So long as no Lease Rental Payment Default,
              --------------                                              
Bankruptcy Default or Event of Default shall have occurred and be continuing,
Lessee may, without the consent of or prior notice to Lessor, (x) assign its
leasehold interest in this Lease, in whole or in part, including any of Lessee's
rights or options hereunder (a "Lease Assignment"), and (y) sublease, license,

use service contract for the provision of part-time, occasional use transponder
capacity on available Ku-band or C-band transponders on satellites, including
the Satellite, owned or operated by Lessee or any Affiliate thereof and not
expressly required to be made available using any of the Transponders leased

following terms and conditions:

     Agreements shall expressly provide that the rights of any sublessee,

     other termination of this Lease, except that any Use Agreement with a term
     of one (1) year or less shall not be required to be so subject and
     subordinate, so long as, if entered into during the last year of the Basic
     Term or Renewal Term (as applicable), the term of such Use Agreement does
     not extend beyond such Basic Term or Renewal Term (as applicable);

<PAGE>
 
          (ii) Lessee shall remain primarily liable to Lessor for the
     performance of all of the terms of this Lease to the same extent as if such
     Use Agreements had not occurred;

          (iii)  the terms and conditions of such Use Agreements (A) shall
     not be in violation of Applicable Law and (B) shall not be inconsistent
     with the terms of this Lease, provided that the term thereof may extend

     provided in Section 6(d)) the provisions of Section 6(c)(i) above and
     Section 6(e); and

          (iv) except as otherwise provided in Section 6(d), such Use Agreements
     shall prohibit the User from entering into any Further Use Agreements
     without obtaining (x) the written consent of Lessee and (y) an agreement by
     any such User further transferring its rights to comply with the terms and
     conditions of this Section 6(c), including, without limitation, the
     requirement that any such Further Use Agreement be expressly subject and
     subordinate to this Lease to the same extent as such Use Agreement.

          No Lease Assignment shall be made unless:  (i) assignee executes an
assignment and assumption agreement reasonably satisfactory to Lessor, which
agreement shall include the agreement therein that references in the Lease to
"Lessee" shall include, where appropriate, HCG, assignee or both, including,
without limitation, in the context of provisions concerning Events of Default;

agreement shall be delivered by Lessee to Agent; (iv) Lessee shall cause to be
delivered to Agent and Lessor an opinion of counsel to the assignee to the

have confirmed that the Guarantee Agreement shall remain in full force and
effect.

          Subject to the provisions of this Section 6(c) and the Hughes
Agreements, Lessee may render any communications service, so long as the
foregoing provisions of this Section 6(c) shall apply, and Lessee or any
Affiliate thereof may provide Transponder or Transponders capacity by Lessee or
any Affiliate of Lessee to any of their respective customers in the ordinary
course of their respective businesses; provided that no rendering of any such
communications service or the providing of Transponder or Transponders capacity,
and neither the entering into or performing of any agreement related thereto,
shall operate to reduce, excuse or in any way affect the obligations of Lessee
hereunder and under the other Operative Documents or the Hughes Agreements to
which it is a party; and as to which Lessee will remain primarily liable.

contain a provision granting quiet enjoyment to GLA (and its successors and
permitted assigns) under the GLA Sublease during the term thereof), if and so
long as:

               (i) the rental payments provided for the Transponders under the
     GLA Sublease are determined by Lessee, at the time the GLA Sublease is
     entered into, in good faith, after consultation with an independent third
     party to represent the then fair market value to Lessee of the lease of
     such Transponders; and such determination by Lessee shall be conclusive as
     to such market value;

               (ii) effective upon the occurrence of an Event of Default, the
     GLA Sublease is assigned by Lessee to Lessor and collaterally assigned by
     Lessor to Agent as additional Collateral Security within 10 days after the
     occurrence of such Event of Default (and the original copy of the GLA
     Sublease is delivered by Lessee or GLA to Agent during said 10-day period,
     provided that the GLA Sublease being "Proprietary Information" within the

     meaning of Section 16.02 of the Participation Agreement, Agent (or Lessor,
     as applicable) shall hold it subject to the confidentiality requirements of
     Section 16.01 of the Participation Agreement); and

               (iii) at the effective time of such assignment, (A) GLA is not in
     default of its obligations under the GLA Sublease and (B) either the
     creditworthiness of GLA (or its applicable successor or assign) is
     reasonably satisfactory to Owner Participant and a Majority In Interest of
     Noteholders or GLA (or its applicable successor or assign) secures a letter
     of credit for the benefit of Lessor, which letter of credit is collaterally
     assigned by Lessor to Agent as additional Collateral Security, and is in an
     amount and on terms and conditions reasonably satisfactory to Owner
     Participant and a Majority In Interest of Noteholders.

          Lessor agrees that it shall take any and all actions reasonably
requested by Lessee or Agent to cause the collateral assignments to Agent
contemplated by clauses (ii) and (iii)(B) above to be timely effected in a
manner reasonably satisfactory to Agent.

          Except as specifically provided in this Section 6(d), Lessee shall not
have any obligation to assign the User Agreements to Lessor.

          (e) Return of Transponders.  Subject to Section 6(c)(i), any Use

Agreement may by its terms extend, or be extended by the User, beyond the Lease
Term, provided that each Transponder shall, at the time of Redelivery to Lessor
pursuant to Section 10, be free and clear of any continuing rights of or
obligations to any User unless Lessor shall otherwise expressly agree in writing
at the request of Lessee; provided that the provisions of this Section 6(e)

     SECTION 7.  Operation; Maintenance; Compliance with Law; Location of
                 --------------------------------------------------------
Satellite; Substitution of Transponders.
- --------------------------------------- 

          During the Lease Term with respect to any Transponder:

          (a) Operation.  Subject to Section 5(b)(ii), Lessee shall observe and
              ---------                                                        
perform each and every obligation (and shall exercise all rights where failure
to do so would have a material adverse effect on Lessor's interest in the
Transponders upon the expiration or termination of the Lease) of Buyer under the
Purchase Agreement and Owner under the Service Agreement to the extent the same
relate to such

                                      11
<PAGE>
 
Transponder, and shall keep the same in full force and effect.  Lessee shall not
use any Transponder during the Lease Term or authorize any third party to use
such Transponder in breach of the Purchase Agreement, the Service Agreement or
any Applicable Laws applicable to Lessee, Lessor (in its capacity as such
Transponder owner without regard to Applicable Laws applicable to Lessor solely
because of its being engaged in a regulated activity of any type other than the
owning and leasing of the Transponder), Owner Participant (in its capacity as
such Transponder owner without regard to Applicable Laws applicable to Owner
Participant solely because of its being engaged in a regulated activity of any
type other than the owning and leasing of the Transponder), such third party or
such Transponder (in each case, other than Applicable Laws as to which
noncompliance would not have an Adverse Effect), or in violation of any
authorization relating to such Transponder or the Satellite or Lessee issued by
any Governmental Authority having jurisdiction over such Transponder, the
Satellite or Lessee other than (i) any provision of such Applicable Law,
authorization or insurance as to which noncompliance would not have an Adverse
Effect or (ii) unless the validity of such Applicable Law or authorization is
being contested in good faith and by appropriate proceedings (but only so long
as such proceedings do not involve any risk of civil or criminal liability to
Lessor, Owner Participant or Agent, and do not involve any material danger of
the sale, forfeiture, loss or diminution in value of such Transponder or the
rights or interests of Lessor or Owner Participant or Agent under any Hughes
Agreement or any Operative Document and adequate reserves with respect thereto
shall have been established in accordance with GAAP).  As used herein, "Adverse
                                                                        -------
Effect" shall mean that which would materially adversely affect the business,
- ------                                                                       
operations or properties of Guarantor on a consolidated basis or involve any
material danger (x) of the loss of any FCC authorization to operate the
Satellite or maintain it in the orbital location permitted by Section 7(d), (y)
of any material adverse effect on the ability of Lessee to perform its
obligations hereunder and under the Purchase Agreement or of the sale,
forfeiture, loss or diminution in value of any Transponder, or (z) of the
imposition of criminal or civil liability on Lessor, Owner Participant, any Loan
Participant or Agent.

          (b) Maintenance.  Lessee hereby agrees to require Hughes Services to
              -----------                                                     
fulfill all of its obligations under the Service Agreement.  Lessee, as Seller,
shall fulfill all of its obligations under the Purchase Agreement.  Lessee will
pay to Hughes Services on behalf of Lessor an amount equal to all payments
required to be made by Lessor during the Lease Term to Hughes Services under the
Service Agreement as Supplemental Rent pursuant to Section 3(c)(ii), and will on
behalf of Lessor perform all other obligations thereunder required to be
performed by Lessor, with respect to such Transponder during the Lease Term.  So
long as during the Lease Term the Service Agreement or a Substitute Service
Agreement shall have remained in full force and effect and Hughes Services (or a
Substitute Service Provider (as defined below), if applicable) or Lessee shall
have performed all of its obligations, if any hereunder and thereunder, as
applicable, with respect to such Transponder, all maintenance, management and
monitoring responsibilities of Lessee in connection with such Transponder shall
be deemed fulfilled, and Lessee shall have no additional independent obligations
hereunder relating thereto.

          In the event that at any time during the Lease Term the Service
Agreement shall no longer be in full force and effect or Hughes Services shall
fail to perform its obligations thereunder with respect to such Transponder,
Lessee, at its expense, shall maintain, manage and monitor, or cause to be
maintained, managed and monitored, the Satellite and such Transponder in good
working order and repair, ordinary wear and tear excepted, (i) in accordance
with the higher of (A) customary industry standards employed by owners of Ku-
Band transponders on domestic communications satellites or (B) standards at
least equal to those used by Hughes Services or any of its Affiliates prior to
such failure of performance for other transponders on the Satellite or on
another similar satellite owned, leased or

                                      12
<PAGE>
 
operated by Hughes Services or any of its Affiliates (if at the time Hughes
Services or any Affiliate thereof maintains, manages or monitors satellites
similar to the Satellite for similar commercial purposes); (ii) in compliance
with all Applicable Laws (other than Applicable Laws as to which noncompliance
would not have an Adverse Effect); and (iii) in accordance with all applicable
requirements of any insurance policy then in effect that is required by Section
9 hereof.  The foregoing notwithstanding, if, with respect to any Transponder,
Contractor or Substitute Service Provider is unable temporarily to perform its
maintenance obligations under the Service Agreement or any Substitute Service
Agreement due to any Force Majeure Event, then, provided such temporary failure
to perform does not cause a permanent material diminution in the value of such
Transponder and is capable of cure before any such permanent diminution in value
would result, such failure shall not constitute a breach of Lessee's obligations
under this Lease.

          Without limiting the generality of the foregoing, at any time during
the Lease Term, if the Service Agreement shall not be in effect, Lessee will
arrange for Lessor to enter into and Lessee will keep in full force and effect
for the remainder of the Lease Term an agreement for the provision of services
(the "Substitute Service Agreement") comparable to those to be provided by
      ----------------------------                                        
Hughes Services under the Service Agreement at a reasonable cost with a sound
and reputable service provider, which may or may not be an Affiliate of Hughes
Services (the "Substitute Service Provider"), and which such provider shall be
               ---------------------------                                    
reasonably acceptable to Lessor and, for so long as the Loan Agreement shall be
in effect, Agent.  If Lessor enters into a Substitute Service Agreement, it will
assign its rights under such agreement to Lessee during the Lease Term on the
terms and conditions contained in Section 5(b)(ii).

          (c) Compliance with Law.  During the Lease Term with respect to any
              -------------------                                            
Transponder, Lessee or Contractor shall have and maintain all permits, licenses
and approvals required by the FCC or under any Applicable Law to operate the
Satellite and such Transponder and shall satisfy the requirements of the FCC and
any statute, regulation or order applicable to operators, users or lessees of
such Transponder; provided, however, that Lessee shall not be deemed to have
                  --------  -------                                         
breached the foregoing covenant unless such non-maintenance or non-satisfaction
would have an Adverse Effect.  To the extent permitted by law, Lessee or any
Affiliate thereof shall prepare and file in timely fashion, or, where Lessor,
Owner Participant or Agent shall be required so to file, prepare and deliver to
such Person within a reasonable time prior to the date for filing, any reports
with respect to any Transponder which are required to be filed with any
Governmental Body during the Lease Term for such Transponder.  Lessor shall
notify Lessee promptly after Lessor has Actual Knowledge of any reports or
filings required of Lessor by law in connection with its ownership of the
Transponders; provided, however, that Lessor shall not incur any liability to
              --------  -------                                              
Lessee for failure so to notify Lessee.  If Lessee shall fail to timely prepare,
deliver or file any such report solely as a result of the failure of Lessor,
Owner Participant or Agent timely to provide Lessee with (i) any information
required in such report which is in the possession of Lessor, Owner Participant
or Agent and is not reasonably available to Lessee or (ii) notice of the
requirement of such report if such report is required as to Lessor, Owner
Participant or Agent for any reason other than such Person's interest in the
Transponder or Transponders then subject to this Lease, Lessee shall incur no
liability to any such Person failing to provide such information or notice to
the extent such liability is incurred by the failure to provide such information
or notice (unless Lessee already had Actual Knowledge of such requirement,
Lessee fails to request such information from such Person and such failure has
an Adverse Effect).  Lessor hereby appoints Lessee its attorney-in-fact, to the
extent permissible by Applicable Law, to execute such reports in the name of
Lessor and to file such reports, and Lessor shall cooperate in furnishing Lessee
such information as is available to it which must be included in such reports.
Upon demand, Lessee shall reimburse Lessor, Owner Participant or Agent on

                                      13
<PAGE>
 
an After-Tax Basis for any reasonable out-of-pocket costs incurred by each such
Person, respectively, in connection with the preparation and filing of any such
reports.  Lessee shall, on a periodic basis, furnish Lessor, Owner Participant
or Agent, as applicable, with a copy of all reports filed by Lessee on behalf of
such Person pursuant to this Section 7(c).

          (d) Location of Satellite.  During the Lease Term, Lessee shall not
              ---------------------
move (or cause or suffer to be moved) or seek to move the Satellite to an
orbital location different from the Permanent Orbital Location for the remaining
useful commercial life of such Satellite; provided, however, that Lessee (i)
                                          --------  -------                 
may, and shall be obligated to, move the Satellite at any time or times if
required to comply with a requirement of the FCC (an "FCC Ordered Move") and
                                                      ----------------      
(ii) may seek to move, and may move, the Satellite as part of an overall
industry process which will increase or decrease the number of, or reallocate
the, available orbital locations and which involves a substantial number of
satellites being moved in a coordinated manner.  Neither Lessee nor any of its
Affiliates shall seek any order or approval from the FCC requiring or allowing
the movement of the Satellite other than pursuant to clause (ii) of the proviso
to the immediately preceding sentence.

          (e) Substitution of Transponder.  Lessee shall have the right, in its
              ---------------------------                                      
discretion, subject to the conditions set forth in this Section 7(e) to
substitute (a "Substitution"), from time to time during the Lease Term, for any
               ------------                                                    
Transponder leased hereunder another transponder of the same type (including,
without limitation, with respect to preemptibility) and power aboard any other
satellite owned by Lessee or an Affiliate of Lessee (a "Replacement
                                                        -----------
Transponder").  Upon fulfillment of the conditions specified in this Section
- -----------
7(e), such Replacement Transponder shall be conveyed by Lessee to Lessor and
leased to Lessee hereunder.

          The Substitution of a transponder pursuant to this Section 7(e) (or
Section 12(a)) shall be subject to fulfillment of the following conditions
precedent on the date of the proposed Substitution at Lessee's sole cost and
expense (and, in the case of clauses (iii), (iv), (v), (vi), (vii), (viii),
(ix), (x) and (xi) to the reasonable satisfaction of Lessor):  (i) no Bankruptcy
Default or Event of Default shall have occurred and be continuing or will exist
immediately following the proposed Substitution; (ii) on the date of such
Substitution, the Replacement Transponder (A) shall meet the applicable
Transponder Performance Specifications set forth in Appendix D-1 to the Purchase
Agreement, (B) shall have a remaining useful commercial life equal to or greater
than the Transponder it is replacing, and (C) a Narrow Ku-Band Transponder shall
only be substituted for a Narrow Ku-Band Transponder and a Wide Ku-Band
Transponder for a Wide Ku-Band Transponder, and, in each case, such Replacement
Transponder shall have the same or greater value, utility and estimated residual
value as the Transponder it is replacing (all of (A), (B) and (C) as determined
pursuant to an appraisal performed by an appraiser selected by Lessee within ten
(10) Business Days of written notice from Lessee of a proposed Substitution,
which appraisal shall be performed within 30 days of the selection of the
appraiser); (iii) Lessor shall have received a bill of sale substantially in the
form of the Bill of Sale conveying title to such Replacement Transponder to
Lessor; (iv) if so requested by Lessor, or for so long as the Loan Agreement
shall be in effect, by Agent, Lessee shall have entered into a Lease Supplement
covering such Replacement Transponder and, if so requested by Agent, Lessor
shall have delivered a Loan Agreement Supplement to Agent; (v) Lessor shall
receive good and marketable title to such Replacement Transponder free and clear
of all Liens other than Permitted Liens of the type specified in clauses (a) and
(b) of the definition thereof; (vi) such Replacement Transponder shall be
covered by an assignment and consent instrument similar in form and substance to
the Consent and Agreement; (vii) Lessee shall have made arrangements reasonably
satisfactory to Lessor for Lessor to enter into the Service Agreement or the

                                      14
<PAGE>
 
Substitute Service Agreement or, if not then in effect, a service agreement
reasonably acceptable in form and substance to Lessor and, for so long as the
Loan Agreement shall be in effect, Agent with respect to the Replacement
Transponder; (viii) Lessee shall have delivered to Lessor and, for so long as
the Loan Agreement shall be in effect, Agent a certificate from an officer of
Lessee that the Replacement Transponder meets the required standards set forth
in (A), (B) and (C) of clause (ii), above; (ix) Lessee and Lessor (with the
consent of Agent, not to be unreasonably withheld, for so long as the Loan
Agreement shall be in effect) shall have entered into a transponder purchase
agreement, transponder service agreement and lease agreement covering such
Replacement Transponder on terms substantially similar to those contained in the
Purchase Agreement, Service Agreement and this Lease, respectively, such
agreements modified only to reflect the differences in the orbital location,
useful commercial life and other attributes unique to such other satellite, the
transponders thereon, and then-existing contractual commitments to owners of any
such transponders on such other satellite, provided that such then-existing
contractual commitments are substantially similar to the contractual commitments
to owners of transponders on the Satellite (each such agreement to be deemed for
all purposes thereafter, a Hughes Agreement or Operative Document, as
applicable); (x) if requested by Owner Participant, Owner Participant shall have
received from tax counsel a tax opinion to the effect that the Owner Participant
is not incurring additional income tax risk as a result of such Substitution or,
in lieu of such tax opinion, and provided there is, in the opinion of tax
counsel, a reasonable basis for taking the reporting position requested by
Lessee, a tax indemnity by Lessee reasonably satisfactory to Owner Participant;
(xi) so long as the Loan Agreement is in effect, the provisions of Sections
15(a) and 15(b) of the Loan Agreement shall have been satisfied; and (xii) an
opinion of counsel delivered to Lessor as to the enforceability of the
agreements referred to in clause (ix) above, subject to customary exceptions.
If requested by Owner Participant, Lessor shall cause tax counsel to determine,
within five (5) Business Days of Lessee's written notice to Lessor of Lessee's
intent to exercise the foregoing Substitution right, whether it can provide the
tax opinion referred to in clause (x), above.

          Upon the fulfillment of the foregoing conditions, Lessor will Transfer
to Lessee all of Lessor's right, title and interest in and to the Transponder to
be replaced as is, where is, free and clear of all Lessor Liens and Owner
Participant Liens, but otherwise without warranty, and will deliver to Lessee
such instrument as Lessee shall reasonably request releasing such Transponder
from this Lease.  Upon such Substitution for all purposes hereof, such
Replacement Transponder shall be deemed to be a "Transponder" hereunder.

     SECTION 8.  Termination.
                 ----------- 

          (a)    Early Termination.
                 ----------------- 

                 (i) Provided that no Lease Rental Payment Default, Bankruptcy
     Default or Event of Default shall have occurred and be continuing, in the
     event that Lessee shall in good faith determine that the Transponders, in
     the aggregate, have become uneconomic, obsolete or surplus to Lessee's
     requirements (as evidenced by a resolution to such effect adopted by the
     Board of Directors of Lessee), Lessee shall have the option, during the
     Basic Term (but not during any Renewal Term), upon furnishing a notice to
     Lessor and Agent at least 180 days prior to the effectiveness thereof to
     terminate this Lease with respect to all, but not less than all, of the
     Transponders on any Rent Payment Date on or after the fifth anniversary of
     the Commencement Date (the "Termination Date").  As a condition to any
                                 ----------------                          
     transfer by Lessor of the Transponders or retention by Lessor of the
     Transponders (each pursuant to this Section 8), any necessary

                                      15
<PAGE>
 
     regulatory approvals in connection therewith shall have been obtained
     (Lessee hereby agreeing to use reasonable best efforts to obtain or to
     assist Lessor in obtaining such approvals).

               During the period from the giving of such notice of termination
     for the Transponders until 60 days prior to the Termination Date, Lessee,
     as non-exclusive agent for Lessor, shall use commercially reasonable
     efforts to solicit unconditional cash bids from Persons other than Lessee
     or its Affiliates to purchase such Transponders on the Termination Date,
     and Lessee shall, during the period from the giving of such notice of
     termination until 60 days prior to the Termination Date (as set forth in
     the preceding paragraph), from time to time at the request of Lessor or
     Agent, inform Lessor and Agent of the results of its efforts and shall
     certify to Lessor and Agent, at least 60 days prior to the Termination
     Date, the amount and terms of each such bid which has theretofore been
     submitted and the name and address of the party submitting such bid.
     Lessor and Owner Participant shall each have the right to solicit bids or
     each to make its own bid, provided that any bid by Lessor or Owner
     Participant shall be submitted to Lessee prior to the disclosure by Lessee
     to Lessor or Owner Participant of any other bids, but shall be under no
     duty to solicit bids or to inquire into the efforts of Lessee to obtain
     bids.  Each such bid (a) shall be for payment in full in cash and (b) shall
     not involve any consideration to be received by Lessee or its Affiliates or
     be connected, directly or indirectly, with any transaction between the
     purchaser and the Lessee or its Affiliates, (collectively, a "Bona Fide
                                                                   ---------
     Bid").  On or prior to the 40th day prior to the Termination Date, Lessee
     ---
     may (provided that Lessee has not previously canceled a proposed
     termination except for a deemed cancellation as provided in Sections
     8(a)(ii) and 8(c) hereto), by notice to Lessor and Agent, cancel the
     proposed termination of this Lease for the Transponders, whereupon this
     Lease shall continue in full force and effect with respect to the
     Transponders.

               If Lessee does not cancel such proposed termination as set forth
     in the last sentence of the preceding paragraph and any Bona Fide Bids are
     received on or prior to the 60th day before the Termination Date, Lessee's
     notice of termination shall become irrevocable on the 10th Business Day
     prior to the Termination Date and Lessor shall on the Termination Date,
     provided that the conditions of subsection (b) have been fulfilled, sell
     such Transponders to the bidder which shall have submitted the highest Bona
     Fide Bid for such Transponders and which has not defaulted on its bid (or
     to the next successively highest bidders, if any, which shall have
     submitted Bona Fide Bids, in the case of a default by the prior bidder,
     provided such sale shall have been consented to by Lessee if the Bona Fide
     Bid related thereto is for an amount less than the applicable Termination
     Value for the Transponders) for such Transponders upon receipt in
     immediately available funds of the amount specified in such bid.  Such
     funds shall be paid either to Agent or to Lessor, as required pursuant to
     the Loan Agreement.  All reasonable out-of-pocket costs and expenses
     incurred by Lessor or Agent including, without limitation, attorneys' fees,
     in connection with any notice of termination, regardless of whether a sale
     is completed or Lessee withdraws its notice of termination, shall be paid
     by Lessee on an After-Tax Basis.

               (ii) If no sale of the Transponders shall have occurred in
     accordance with Section 8(a)(i) on the Termination Date, or if all bidders
     having submitted Bona Fide Bids for such Transponders that were for an
     amount at least equal to Termination Value for the Transponders (or if for
     less than such Termination Value, the sale to such bidder was consented to
     by Lessee) have defaulted on such bids, then the Lease shall continue in
     full force and effect and the termination notice given by Lessee shall be
     deemed to have been canceled by Lessee.

                                      16
<PAGE>
 
     If no sale of the Transponders shall have occurred in accordance with
     Section 8(a)(i), as a result of a default by Lessor in its obligation to
     sell the Transponders in accordance with Section 8(b), then Lessor shall
     have been deemed to have exercised its election to retain ownership of the
     Transponders pursuant to Section 8(c) hereof.

               (iii)  Notwithstanding anything to the contrary in this Section
     8(a), if the bidder to whom the sale would otherwise have taken place shall
     have defaulted on its bid within the ten (10) Business Day-period ending on
     the Termination Date, Lessee shall nonetheless make, on the Termination
     Date, (A) all the payments specified in the first sentence of Section 8(b)
     (but not the payment called for by the second sentence of Section 8(b)),
     and (B) payment of Termination Value for the Transponders as of the
     Termination Date.  Promptly thereafter, Lessor shall use its reasonable
     commercial efforts to sell the Transponders to an unaffiliated third party.
     Lessor shall retain the net proceeds of any such sale in excess of
     Termination Value for such Transponders as of the Termination Date and pay
     to Lessee the net proceeds of such sale up to but not exceeding Termination
     Value for such Transponders as of the Termination Date within five (5)
     Business days of receipt of the proceeds of such sale.  Upon payment by
     Lessee of all the amounts due pursuant to this Section 8(a)(iii), the
     obligation of Lessee to pay Base Rent with respect to the Transponders and
     Supplemental Rent, other than to pay Supplemental Rent attributable to
     acts, events or conditions occurring or existing on or prior to such
     termination with respect to the Transponders or as otherwise expressly
     provided in the Tax Indemnification Agreement, if any, shall terminate, the
     Transponders shall no longer be subject to this Lease and the Lease Term
     with respect to the Transponders shall end.

          (b) Termination Payments.  As a condition to the obligation of Lessor
              --------------------                                             
to terminate the Lease and to sell the Transponders pursuant to Section 8(a) on
the Termination Date therefor, Lessee shall on the Termination Date pay to
Lessor the sum of (A) all unpaid Base Rent due on or before such Termination
Date with respect to the Transponders, if any, and (B) any other Rent with
respect to such Transponders due and unpaid as of such Termination Date
(excluding Termination Value and any Scheduled Rent designated as "advance rent"
on Schedule A hereto with respect to the Termination Date).  In addition, Lessor
shall retain the net proceeds of such sale of the Transponders and Lessee shall
pay to Lessor the excess, if any, of Termination Value for the Transponders
(computed as of the Termination Date) over such net sales proceeds.  Upon
payment by Lessee of the amounts due pursuant to this Section 8(b), the
obligation of Lessee to pay Base Rent and Supplemental Rent, other than
Supplemental Rent attributable to acts, events or conditions occurring or
existing on or prior to such termination with respect to the Transponders shall
terminate, the Transponders shall no longer be subject to this Lease and the
Lease Term with respect to the Transponders shall end.

          (c) Retention of Transponders by Lessor.  If Lessee shall elect to
              -----------------------------------                           
terminate this Lease pursuant to Section 8(a), Lessor may, subject to Lessee's
right to cancel the proposed notice of termination, elect to retain rather than
sell the Transponders by giving irrevocable notice to Lessee and Agent no later
than 45 days prior to the Termination Date.  If Lessor so elects to retain the
Transponders, on the Termination Date (i) Lessor shall pay to Agent an amount
equal to the unpaid principal amount of and accrued interest on the outstanding
Notes, (ii) Lessee shall pay to Lessor or the Person entitled thereto as
provided in the Operative Documents on the Termination Date (A) all unpaid Base
Rent due on or before such Termination Date with respect to the Transponders, if
any, and (B) any other Rent with respect to the Transponders due and unpaid as
of such Termination Date (excluding Termination Value or, if the Transponders
are sold, any amounts required to be paid by Lessee pursuant to the second

                                      17
<PAGE>
 
sentence of Section 8(b) and any Scheduled Rent designated as "advance rent" on
Schedule A hereto with respect to the Termination Date), (iii) this Lease and
the obligations of Lessee hereunder shall terminate, other than Lessee's
obligation to pay Supplemental Rent attributable to acts, events or conditions
occurring or existing on or prior to such termination or as otherwise expressly
provided in the Tax Indemnification Agreement, if any, and (iv) Lessor shall
execute and deliver to Lessee, at Lessee's reasonable expense, such instruments
as Lessee shall reasonably request to evidence the termination of this Lease.
In the event Owner Participant fails to make funds available to Owner Trustee to
enable Lessor to pay the amounts specified in clause (i) of this Section 8(c) or
Lessee fails to pay the amounts specified in clause (ii) of such sentence,
Lessee shall be deemed to have canceled its notice of termination and the Lease
shall continue in full force and effect (and in the case of Lessor's failure to
pay the amounts set forth in clause (i), above, Lessee shall have the right to
enforce the obligations of Owner Participant as set forth in Section 5.02(j) of
the Participation Agreement).

          (d) No Duplication of Rent Differential Amount.  In the event that
              ------------------------------------------                    
there is a portion of the Scheduled Rent on any Termination Date that is
designated as "arrears rent" on Schedule A and there is also a portion that is
designated as "advance rent", a portion of the Rent Differential Amount with
respect to such Termination Date shall be added to the Scheduled Rent designated
as an "arrears rent" due on such date and the remainder of such Rent
Differential Amount shall be taken into account in the computation of
Termination Value pursuant to the definition of Termination Value.  It is
intended that, whether or not Termination Value is payable on such Termination
Date, the entire amount of the Rent Differential Amount due on such Termination
Date shall be allocated between the Scheduled Rent designated as an "arrears
rent" due on such date and the computation of Termination Value, as appropriate
and without duplication, in such manner as will preserve the Owner Participant's
Net Economic Return and comply with the minimum payment requirement contained in
Section 3(f) (it being understood that the entire amount of such Rent
Differential Amount shall be taken into consideration in making such
allocation).

     SECTION 9.  Insurance.
                 --------- 

          (a) Non-Discrimination.  Lessee shall maintain general liability
              ------------------                                          
insurance and/or life or casualty insurance with respect to the Satellite and
the Transponders in such amounts, if any, that Lessee deems prudent and cost-
effective but, in any event, Lessee shall maintain such insurance for not less
than the amounts, and on terms and conditions no less favorable than the terms
and conditions that Lessee and its Affiliates customarily maintain for similar
events or occurrences with respect to similar transponders owned for tax or book
purposes by Lessee or its Affiliates on similar satellites (the "Hughes
                                                                 ------
Customary Terms," which terms may include deductibles customarily maintained by
- ---------------                                                                
Lessee or its Affiliates), provided, however, that the foregoing shall not
                           --------  -------                              
require Lessee to maintain life or casualty insurance for the Transponders in an
amount in excess of Stipulated Loss Value for such Transponders.

          (b) Additional Insureds.  All insurance policies, if any, carried in
              -------------------                                             
accordance with this Article 9 and all policies taken out in substitution or
replacement for any such policies (i) shall name Lessor (in its individual
capacity and as Owner Trustee), Owner Participant, and (so long as the Loan
Agreement shall be in effect) Agent, as additional insureds, as their respective
interests may appear (but without imposing upon any such parties any obligation
imposed upon the insured, including without limitation, the liability to pay the
premium for such policies) and in the case of life or casualty insurance
pursuant to Section 9(a), Agent (so long as the Loan Agreement shall be in
effect) and Lessor shall be named as "loss payees," as their interests may
appear; (ii) shall provide that any loss (other than a loss

                                      18
<PAGE>
 
under general liability insurance) shall be adjusted by Lessee with the
insurance carriers and be payable to Lessor (or, so long as the Loan Agreement
shall be in effect, Agent), for application as provided in Section 12 hereof or
Section 5 of the Loan Agreement; and (iii) shall provide that if such insurance
is changed in any material adverse respect in relation to the interests of
Lessor or Owner Participant (and for so long as the Loan Agreement shall be in
effect, Agent), or if such insurance is allowed to lapse for non-payment of
premium, or is invalidated by any action or inaction of Lessee or any other
Person (other than action or inaction by Lessor or Owner Participant or Agent,
as the case may be), such change, lapse or invalidation shall not be effective
as to Lessor, Owner Participant and (so long as the Loan Agreement shall be in
effect) Agent for at least 30 days after receipt by Lessor, Owner Participant
and (so long as the Loan Agreement shall be in effect) Agent of written notice
from such insurers, their agents or Lessee of such lapse.  Each insurance policy
provided under this Section 9 shall be primary without right of contribution
from any other insurance which is carried by Lessor and Owner Participant or
Agent with respect to their respective interests as such in the Transponders.

          (c) Separate Insurance.  Nothing contained in this Lease shall prevent
              ------------------                                                
Lessor, Owner Participant, Agent or Lessee, each at its own expense and for its
exclusive benefit, from carrying excess life or casualty insurance covering the
Transponders in addition to the life or casualty insurance, if any, carried by
Lessee under Section 9(a) (any such life or casualty insurance being herein
called "Additional Insurance"); provided, however, that Lessee shall not be
        --------------------    --------  -------                          
entitled to obtain any such Additional Insurance for the Transponders unless
Lessee shall then maintain life or casualty insurance for such Transponders in
an amount at least equal to the Stipulated Loss Value for such Transponders from
time to time set forth in Schedule B hereto corresponding to such date.  If
                          ----------                                       
there shall be any limitation with respect to the amount of Additional Insurance
that Lessor, Owner Participant, Agent or Lessee may obtain, whether as a result
of market capacity or otherwise, then each such party shall have the right to
purchase an amount of Additional Insurance for the Transponders as its interests
may then appear.  Prior to obtaining any Additional Insurance, Lessor, Owner
Participant or Agent shall provide Lessee with reasonable notice of the
Additional Insurance (including the proposed terms thereof) intended to be
obtained by it, including evidence satisfactory to Lessee that such proposed
terms shall be consistent with the terms of such insurance as may be carried by
Lessee under this Article 9.

     SECTION 10.  Redelivery.
                  ---------- 

              (a) Redelivery Terms.  At the expiration or earlier termination 
                  ----------------                                            
of the Lease Term with respect to any Transponder, if Lessee does not renew this
Lease with respect to such Transponder and does not purchase such Transponder,
Lessee shall, at Lessee's cost and expense, redeliver such Transponder to Lessor
in the condition required by Section 7 hereof including, without limitation, in
the location permitted by Section 7(d) hereof and, in connection with such
Redelivery, Lessee shall supply Lessor with the name, last known address and
telephone number of the most recent User (other than Users under Occasional Use
Service Contracts) with respect to such Transponder. In the event of any
Redelivery of any Transponder, Lessee shall execute and deliver to Lessor an
instrument substantially in the form of Exhibit A to this Lease that shall
                                        ---------                         
constitute evidence of surrender by Lessee of all of Lessee's rights to such
Transponder under this Lease and the Hughes Agreements applicable thereto;
provided, however, that Lessee's Redelivery of any Transponder hereunder shall
- --------  -------                                                             
not by itself affect the validity and effectiveness of the Purchase Agreement,
Service Agreement or any Substitute Service Agreement relating to such
Transponder, as applicable.  At the time of any Redelivery, such Transponder
shall be free and clear of all Liens (other than Permitted Liens described in
clause (a) or (b) of the definition thereof, excluding Lessor Liens and Agent
Liens, and other than the Lien of the GLA Sublease)

                                      19
<PAGE>
 
and free and clear of any right of any Person to use or access such Transponder
other than GLA under the GLA Sublease, Lessor or Owner Participant, unless Owner
Participant shall consent to a request by Lessee to recognize any right of any
Person to use or access such Transponder other than Lessor and Owner
Participant; and Lessee shall be in compliance with Sections 7(b) and (c).

          (b) Decreased Value.  If, at the end of the Basic Term, Lessee shall
              ---------------                                                 
return to Lessor any Transponder, and the estimated fuel remaining on the
Satellite at the Redelivery date (as reasonably determined by Lessee using
standard industry procedures) as indicated in an Officer's Certificate delivered
by Lessee to Lessor on such date is less than 50% of the amount of fuel
originally estimated by the Appraiser in the Commencement Date Appraisal as
necessary for the residual value of the Satellite to be as set forth in the
Commencement Date Appraisal (the "In-Service Date Projection"), then Lessee
                                  --------------------------               
shall pay to Lessor an amount (the "Decreased Value") equal to the excess of (1)
                                    ---------------                             
the estimated Fair Market Sales Value of such Transponder as of such Redelivery
date, based on the assumption that such Transponder had a remaining useful
commercial life equal to 50% of the In-Service Date Projection over (2) the Fair
Market Sales Value of such Transponder caused by such lower amount of fuel,
determined as of the Redelivery date (the "Decreased Value Payment").  Lessee
                                           -----------------------           
shall pay to Lessor the Decreased Value Payment upon the later of the Redelivery
date or five (5) days after the Decreased Value of such Transponder is
determined in accordance with the Appraisal Procedure (which procedure shall
commence not later than 120 days prior to Redelivery if the existence of a
condition requiring a payment of Decreased Value is ascertainable at such time
or as soon thereafter as is reasonably possible if it not so ascertainable).

          (c) If, at the end of the Lease Term, Lessee shall return to Lessor
any Transponder that remains subject to the GLA Sublease and the rentals payable
under the GLA Sublease with respect to such Transponder are less than the Fair
Market Rental Value of such Transponder during the balance of the term of the
GLA Sublease (as then in effect), then Lessee shall pay to Lessor from time to
time while the GLA Sublease shall continue in full force and effect, an amount,
if any, equal to the lesser of (i) the amount, if any, by which the Fair Market
Rental Value of such Transponder exceeds the rental payable under the GLA
Sublease and (ii) the amount, if any, by which 50% of the full-time monthly
lease rate contained in the Commencement Date Appraisal exceeds the rental
payable under the GLA Sublease; provided that Lessee's payment obligation under
                                --------                                       
this paragraph (c) shall cease at such time as the GLA Sublease terminates in
accordance with its terms as in effect on the date the Transponder is returned
to Lessor by Lessee, or earlier expiration of its term for any reason
whatsoever.

     SECTION 11.  Cooperation.
                  ----------- 

              (a) Lessor's Efforts to Sell or Lease. Lessee agrees that during
                  ---------------------------------
the last 540 days of the Basic Term or the Renewal Term (unless Lessee has
provided Lessor with the Preliminary Notice stating that it will renew the Lease
or purchase the Transponders pursuant to Section 18 or 19, respectively, and in
such case no Bankruptcy Default or Event of Default shall have occurred and be
continuing), it will cooperate in all reasonable respects with efforts of
Lessor, subject to the provisions of Section 6(d), to lease or sell such
Transponder, including aiding potential lessees or purchasers by providing all
data relating to maintenance and performance for inspection which Owner under
the Service Agreement and Buyer under the Purchase Agreement are entitled to
receive or inspect subject to any confidentiality requirements set forth in such
agreements. Further, Lessee shall notify existing users of such Transponder of
the end of the Lease Term and use reasonable best efforts to assist Lessor in
obtaining any necessary regulatory approvals to operate, lease or sell such
Transponder, at Lessor's

                                      20
<PAGE>
 
reasonable cost and expense and on an After-Tax Basis to Lessee.  In addition,
Lessee shall furnish to Lessor such information as it supplies to potential
lessees or purchasers of transponders that it owns or leases on the Satellite or
other similar satellites.

          (b) Value and Useful Life Determinations.  Lessee shall provide Lessor
              ------------------------------------                              
at any time with information which, in the reasonable opinion of Lessor, is
necessary or material for Lessor to negotiate and reach an agreement for any
determination of Fair Market Sales Value, Fair Market Rental Value and estimated
remaining useful commercial life; provided, however, that Lessee shall not be
                                  --------  -------                          
required to disclose confidential information unrelated to the performance or
maintenance of the Transponders.

     SECTION 12.  Loss, Destruction, Condemnation or Damage.
                  ----------------------------------------- 

          (a) Payment of Stipulated Loss Value.  If with respect to any
              --------------------------------                         
Transponder an Event of Loss occurs, then Lessee shall forthwith (and, in any
event, within seven (7) days of such occurrence) give Lessor and Agent notice of
such Event of Loss (the "Casualty Notice"), which notice shall include, if
                         ---------------                                  
applicable, Lessee's election to provide a Replacement Transponder in accordance
with the last sentence of this paragraph and shall also state whether the
proviso to this sentence shall be applicable by reason of Lessee's having in
force insurance against loss or damage to the Transponders, pursuant to Section
9 or voluntarily, and on the Casualty Payment Date first occurring not less than
30 days after the date of such notice, Lessee shall pay to Lessor an amount
equal to the sum of (x) the Stipulated Loss Value for such Transponder due on
such Casualty Payment Date and (y) the sum of (A) all unpaid Base Rent due on or
before such Casualty Payment Date with respect to such Transponder, if any, and
(B) any other Rent with respect to such Transponder due and unpaid as of such
Casualty Payment Date (excluding Stipulated Loss Value and any Scheduled Rent
designated as "advance rent" on Schedule A hereto with respect to such Casualty
Payment Date); provided, however, that if, with respect to such Transponder,
               --------  -------                                            
Lessee shall have in force insurance against loss or damage to the Transponders,
pursuant to Section 9 or voluntarily, then subject to the provisions of Section
12(b), Lessee shall pay to Lessor in immediately available funds on the Casualty
Payment Date first occurring not less than thirty (30) days after the date of
the Casualty Notice, the amount specified in clause (x) of this Section less the
amount of such insurance with respect to such Transponder and, within ten (10)
days after receipt of any such insurance proceeds (but in no event later than
120 days after the date of such Casualty Notice) the amount specified in clause
(x) of this Section to the extent not previously paid, and to the extent of any
such payment to be made from such insurance proceeds or otherwise after the
Casualty Payment Date referred to above, Lessee shall pay interest from such
Casualty Payment Date on such amount to but excluding the date of payment at the
Applicable Rate borne by the Notes then outstanding as to which the insurance
proceeds shall be applied, and otherwise at the Prime Rate; provided, further
                                                            --------  -------
that, in the case of an Event of Loss of the type described in clause (f) of the
definition thereof, the amount due on the applicable Casualty Payment Date in
accordance with clause (x) of this Section 12(a) shall be the higher of
Stipulated Loss Value and the Fair Market Sales Value for the Transponder
(determined pursuant to the Appraisal Procedure based on the assumption that the
Satellite had not been removed from orbit) on such Casualty Payment Date.  In
lieu of making the foregoing payment, and so long as, but only so long as, no
Bankruptcy Default or Event of Default has occurred and is continuing, Lessee
may, at its option, notify Lessor and Agent of its intent to, and thereafter
provide Lessor (on the Casualty Payment Date first occurring not less than
thirty (30) days after the date of the Casualty Notice) with a Replacement
Transponder, in accordance with, and subject to, the provisions and the
conditions in Section 7(e).

                                      21
<PAGE>
 
          Upon payment in full of all amounts due or the provision of a
Replacement Transponder pursuant to the preceding paragraph, Lessor (as seller)
shall transfer the Transponder suffering such Event of Loss to Lessee, free and
clear of all Lessor Liens and Owner Participant Liens, but otherwise without
warranty, the obligation of Lessee to pay Base Rent with respect to such
Transponder shall terminate, but shall continue as to any Replacement
Transponder, such Transponder shall no longer be subject to this Lease and the
Lease Term with respect to such Transponder shall end, but shall apply to any
Replacement Transponder.

          (b) Application of Payments upon an Event of Loss.  Subject to the
              ---------------------------------------------                 
provisions of Section 12(d), and notwithstanding any rights of Lessor as owner
of the Transponders, any payments received at any time by Lessor from any
Governmental Body or other Person as a result of the occurrence of an Event of
Loss with respect to a Transponder (including proceeds with respect to such
Transponder from insurance, if any, but excluding proceeds from Additional
Insurance with respect to such Transponder carried by Lessor, Owner Participant
or Agent) shall be applied as follows:

               (i) so much of such payments as shall not exceed the amount of
     Stipulated Loss Value, if any, required to be paid with respect to such
     Transponder by Lessee pursuant to Section 12(a) shall be applied in
     reduction of Lessee's obligation to pay such amount with respect to such
     Transponder if not already paid by Lessee, or, if already paid with respect
     to such Transponder by Lessee, shall be applied to reimburse Lessee for its
     payment of such amounts, or if Lessee shall have provided Lessor with a
     Replacement Transponder pursuant to Section 12(a), shall be paid to Lessee
     upon conveyance of such Replacement Transponder to Lessor; and

               (ii) the excess, if any, of such payments with respect to such
     Transponder remaining thereafter shall be allocated between Lessor and
     Lessee as their respective interests may appear (except to the extent
     reflecting proceeds of insurance (other than additional insurance
     maintained by Owner Participant, Owner Trustee or Agent), which shall be
     paid to and retained by Lessee).

          (c) Application of Payments Not Relating to an Event of Loss.  In the
              --------------------------------------------------------         
event of any loss, condemnation, confiscation, theft or seizure of, or use of,
or damage to, any portion of any Transponder not constituting an Event of Loss,
Lessee shall promptly notify Lessor and Agent and all of Lessee's obligations
under this Lease with respect to such Transponder shall continue to the same
extent as if such event had not occurred.  Subject to the provisions of Section
12(d), and notwithstanding any implicit or express rights of Lessor as owner of
such Transponder, payments received at any time by Lessor or Lessee from any
insurer under insurance carried by Lessee, from any Governmental Body or from
any other Person with respect to any loss, condemnation, confiscation, theft or
seizure of, or use of, or damage to, any Transponder or any part thereof not
constituting an Event of Loss shall be paid to Lessor or Lessee, as their
interests may appear.

          (d) Applications During Default.  Any amount which may become payable
              ---------------------------                                      
to Lessee pursuant to this Lease arising out of any insurance, warranty,
governmental award or otherwise shall not be paid to Lessee, or if it shall have
been paid to Lessee shall not be retained by Lessee, but shall be paid to Lessor
or Agent, as the case may be, if at the time of such payment a Payment Default,
Bankruptcy Default or an Event of Default shall have occurred and be continuing.
In such event, all such amounts shall be paid to and held by Lessor or, to the
extent required by the Loan Agreement, Agent, in trust as

                                      22
<PAGE>
 
security for the obligations of Lessee, Seller, Contractor or Guarantor to make
payments under this Lease and any other Operative Document or Hughes Agreement
or to pay Rent hereunder or, at the option of such holder, applied by such
holder toward payment of any such obligations of Lessee, Seller, Guarantor or
Contractor at the time due hereunder or under such other Operative Document or
Hughes Agreement.  At such time as there shall not be continuing a Payment
Default, Bankruptcy Default or an Event of Default all such amounts at the time
held by Lessor or Agent, as the case may be, in excess of the amount, if any,
which Lessor or Agent, as the case may be, shall have elected to apply as above
provided shall be paid to Lessee, Seller or Contractor, as appropriate.

          (e) No Duplication of Rent Differential Amount.  In the event that
              ------------------------------------------                    
there is a portion of the Scheduled Rent on any Casualty Payment Date that is
designated as "arrears rent" on Schedule A and there is also a portion that is
designated as "advance rent", a portion of the Rent Differential Amount with
respect to such Casualty Payment Date shall be added to the Scheduled Rent
designated as an "arrears rent" due on such date and the remainder of such Rent
Differential Amount shall be taken into account in the computation of Stipulated
Loss Value pursuant to the definition of Stipulated Loss Value.  It is intended
that the entire amount of the Rent Differential Amount due on such Casualty
Payment Date shall be allocated between the Scheduled Rent designated as an
"arrears rent" due on such date and the computation of Stipulated Loss Value, as
appropriate and without duplication, in such manner as will preserve the Owner
Participant's Net Economic Return and comply with the minimum payment
requirement contained in Section 3(f) (it being understood that the entire
amount of such Rent Differential Amount shall be taken into consideration in
making such allocation).

     SECTION 13.  Merger, Consolidation.
                  --------------------- 

          Lessee shall not consolidate with or merge into any other Person or
convey, transfer or lease all or substantially all of its assets as an entirety
to any Person, unless:

               (i) the successor entity formed by such consolidation or into
     which it is merged or the successor entity which acquires by conveyance,
     transfer or lease all or substantially all of its assets as an entirety
     shall be a corporation organized and existing under the laws of the United
     States of America, any State thereof or the District of Columbia which has
     a substantial part of its properties and assets located within, and
     operates substantially within, the United States of America, and which is
     qualified under the requirements of the FCC and any applicable statute,
     regulation or order to assume Lessee's obligations with respect to the
     Satellite and/or Transponders then subject to this Lease;

               (ii) such successor corporation shall expressly assume in writing
     by instrument or instruments enforceable against it reasonably satisfactory
     in form and substance to Lessor and Owner Participant the due and punctual
     payment, performance and observance of all obligations of Lessee under this
     Lease and any other Operative Document or Hughes Agreement to which Lessee
     is a party in any capacity, with the same effect as if such corporation had
     originally been named Lessee herein or had been a party thereto;

               (iii)  immediately after giving effect to such transaction, no
     Bankruptcy Default or Event of Default shall exist and the Guarantee
     Agreement (or any successor agreement) shall be in full force and effect;
     and

                                      23
<PAGE>
 
               (iv) Lessee shall have delivered to Lessor, Owner Participant and
     Agent an opinion of counsel in scope and substance reasonably satisfactory
     to each stating that such consolidation, merger, conveyance, transfer or
     lease complies with the legal requirements of this Section 13, and to the
     effect that the Guarantee Agreement constitutes a legal, valid and binding
     obligation of Guarantor, enforceable against Guarantor in accordance with
     its terms, subject to customary exceptions.

          Upon any consolidation or merger, or any conveyance, transfer or lease
of all or substantially all of the assets of Lessee as an entirety in accordance
with this Section 13, the successor corporation formed by such consolidation or
into which Lessee is merged or to which such conveyance, transfer or lease is
made shall succeed to, and be substituted for, and may exercise every right and
power of, Lessee under the Operative Documents to which Lessee is a party in any
capacity with the same effect as if such successor corporation had been named
Lessee herein and therein.  No such conveyance, transfer or lease of all or
substantially all of the assets of Lessee as an entirety shall have the effect
of releasing Lessee or any successor corporation which shall theretofore have
become such in the manner prescribed in this Section 13 from its liability
hereunder or under the other Operative Documents or Hughes Agreement to which
Lessee is a party in any capacity.

     SECTION 14.  Reports.
                  ------- 

              (a) Condition and Operation.  Lessor, Owner Participant and Agent
                  -----------------------                                      
shall have the right to obtain and, following any such request by any of them,
Lessee shall provide or request to be provided, information regarding the
condition and state of repair of any Transponder then subject to this Lease,
compliance by Lessee with Sections 7 and 9 and performance of Seller and
Contractor under the Hughes Agreements (it being understood that information
with respect to the performance of Seller and Contractor shall be limited to
that made available pursuant to the Hughes Agreements), and the absence of any
Default or Event of Default or Event of Loss, or event which with the passage of
time or giving of notice or both would become an Event of Loss.  Agent shall
neither have any duty to make any inquiry nor incur any liability or obligation
by reason of not making any such inquiry.

              (b) Liens.  Lessee shall promptly (and in no event later than 
                  -----                               
five (5) Business Days) notify Lessor and Agent after having obtained Actual
Knowledge of the attachment of any Lien which Lessee shall be obligated to
discharge or eliminate pursuant to Section 6(a) unless the same shall already
have been removed or discharged by Lessee.

     SECTION 15.  Events of Default.
                  ----------------- 

          Each of the following events shall constitute an Event of Default
(whether any such event shall be voluntary or involuntary or come about or be
effected by operation of law or pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation of any
Governmental Body or otherwise):

          (a) Lessee shall fail to make any payment of Base Rent, Supplemental
Rent pursuant to Section 3(b)(i), Termination Value, Stipulated Loss Value or
EBO Amount when due and such failure shall continue for ten (10) Business Days;

          (b) Lessee shall fail to make any other payment of Rent when due and
such failure shall continue for ten (10) Business Days after written notice
thereof by Lessor (or Agent); or

          (c) Other than with respect to any covenant of Lessee set forth in
Section 16.02(b) of the Participation Agreement, Lessee shall fail to perform or
observe in any material respect any covenant, condition or agreement to be
performed or observed by it under this Lease or Guarantor shall fail to perform
or observe in any material respect any covenant, condition or agreement to be
performed or observed by it under the Participation Agreement or the Guarantee
Agreement or Lessee, Seller, Contractor or HCG shall fail to perform or observe
in any material respect any other covenant, condition or agreement to be
performed or observed by it under any of the other Operative Documents or Hughes
Agreements to which it is a party (other than any such covenant, condition or
agreement under the Tax Indemnification Agreement, if any, not related to the
payment of money thereunder, provided that the declaration of an Event of
                             --------                                    
Default hereunder with respect to any such covenant, condition or agreement
shall be only upon the instructions of the Owner Participant) and, in each such
case, such failure shall have continued for ninety (90) days after Lessee's
receipt of written notice thereof from Lessor or Agent; provided, however, that
                                                        --------  -------      
if such failure is capable of cure but cannot be cured by payment of money and
cannot be cured by diligent efforts within such 90-day period but such diligent
efforts shall be properly commenced within the cure period and Lessee is
diligently pursuing, and shall continue to pursue diligently, a remedy of such
failure, the cure period shall be extended for an additional period of time as
may be necessary to cure, not to exceed an additional 30 days; or

          (d) any representation or warranty made by Lessee, Seller, HCG or
Contractor in any of the Operative Documents or Hughes Agreements to which it is
a party or in any written statement, report, schedule, notice or other writing
furnished by Lessee, Seller, HCG or Contractor in connection therewith (other
than any representation or warranty under the Tax Indemnification Agreement, if
any) shall prove to have been inaccurate in any material respect at the time
made; provided, however, that if the representation or warranty was originally
      --------  -------                                                       
made in good faith, an Event of Default shall not be deemed to exist unless the
inaccuracy materially adversely affects Lessor, Owner Participant or Agent and
if capable of being cured, remains uncured for a period of ninety (90) days
after receipt by Lessee of written notice from Lessor or Agent of such
inaccuracy; provided, however, that if such Default cannot be cured by payment
            --------  -------                                                 
of money and cannot be cured by diligent efforts within such 90-day period but
such diligent efforts shall be properly commenced within the cure period and
Lessee is diligently pursuing, and shall continue to pursue diligently, a remedy
of such failure, the cure period shall be extended for an additional period of
time as may be necessary to cure, not to exceed an additional 30 days; or

          (e) The Guarantee Agreement shall cease to be valid and binding or in
full force or effect; or

          (f) Lessee or Guarantor shall consent to the appointment of, or taking
of possession by, a receiver, trustee, custodian or liquidator of itself or of a
substantial part of its property, or shall fail to pay its debts generally as
they become due, or shall make a general assignment for the benefit of
creditors; or

          (g) Lessee or Guarantor shall file a voluntary petition in bankruptcy
or a voluntary petition or an answer seeking reorganization in a proceeding
under any applicable bankruptcy or insolvency laws (as now or hereafter in
effect) or an answer admitting the material allegations of a petition filed
against such Person in any such proceeding, or shall by voluntary petition,
answer or

                                      25
<PAGE>
 
consent, seek relief under the provisions of any now existing or future
bankruptcy, insolvency or other similar law providing for the liquidation,
reorganization or winding-up of corporations, or providing for an agreement,
composition, extension or adjustment with its creditors; or

          (h) a receiver, trustee, liquidator or custodian of Lessee or
Guarantor for a substantial part of its property shall be appointed by court
order, or any substantial part of its property shall be sequestered by court
order, or a petition shall be filed, or an involuntary case or other proceeding
commenced, against Lessee or Guarantor under any bankruptcy, reorganization,
arrangement, insolvency, readjustment of debt, dissolution or liquidation law of
any jurisdiction, whether now or hereafter in effect, and such order shall
remain in effect for more than ninety (90) days, or such petition, case or
proceeding shall not be dismissed within ninety (90) days after filing; or

          (i) Lessee shall fail to obtain any insurance required to be obtained
pursuant to Section 9(a) and such failure shall have continued for 30 days, or
if such insurance required pursuant to Section 9(a) shall lapse and Lessee shall
fail to renew or replace such insurance with the required insurance within 30
days from the date of such lapse and such failure shall continue for 30 days
thereafter.

     SECTION 16.  Remedies.  Upon the occurrence of any Event of Default and at
                  --------                                                     
any time thereafter so long as the same shall be continuing, Lessor may at its
option declare this Lease to be in default, and at any time thereafter Lessor
may do any of the following as Lessor in its sole discretion shall elect, to the
extent permitted by, and subject to compliance with any mandatory requirements
of, Applicable Law then in effect and subject to the rights of GLA under the GLA
Sublease:

          (I) Proceed by appropriate court action, either at law or in equity,
to enforce performance by Lessee or Guarantor of the applicable covenants of
this Lease or the Guarantee Agreement or to recover damages for the breach
thereof; and/or

          (II) By notice in writing terminate or cancel this Lease, whereupon
all rights of Lessee to the use of the Transponders or to purchase the
Transponders (whether or not Lessee shall have theretofore made the EBO
Prepayment) shall absolutely cease and terminate; and/or, whether or not Lessor
shall have exercised any other remedy hereunder (other than a sale under clause
(c) below (provided that Lessor may exercise the remedies set forth in clause
(a) below) and other than pursuant to clause (d)(X) below):

               (a) Lessor may, upon written demand and at Lessee's expense,
     cause Lessee to return promptly, and Lessee shall return promptly, all or
     such part of the Transponders as Lessor may so demand to Lessor or its
     order in the manner and condition required by, and otherwise in accordance
     with all the provisions of, Section 10, or Lessor, at its option, may take
     immediate possession of all Lessee's rights and interests in and to the
     same by summary proceedings or otherwise, all without liability accruing to
     Lessor for or by reason of such taking of possession subject to, however,
     the controlling provisions of the Consent and Agreement; and/or

               (b) Lessor, by notice to Lessee specifying a payment date which
     must be a Casualty Payment Date no later than 180 days from the date of
     such notice, may require Lessee to pay to Lessor, with respect to any
     Transponder, and Lessee hereby agrees that it will pay to

                                      26
<PAGE>
 
     Lessor, with respect to such Transponder, on the Casualty Payment Date
     specified in such notice, as liquidated damages for loss of a bargain, and
     not as a penalty, and in lieu of any further payments of Base Rent for any
     period after the Casualty Payment Date specified in such notice, an amount
     (reduced by any amounts previously paid by Lessee pursuant to Section
     16(II)(d)(X)) equal to the sum of the following amounts calculated as of
     such Casualty Payment Date:  (A) all unpaid Base Rent due on or before such
     Casualty Payment Date with respect to such Transponder, if any, and (B) an
     amount equal to the excess (the "SLV Excess"), if any, of Stipulated Loss
                                      ----------                              
     Value for such Transponder over either the EBO Amount for such Transponder
     (if Lessee shall have contemporaneously or previously made the EBO
     Prepayment) or zero (if Lessee shall not have contemporaneously or
     previously made the EBO Prepayment), together with interest, if any, at the
     Overdue Rate on the amounts described in (A) and (B) above from the
     Casualty Payment Date as of which such amounts were calculated until the
     date of actual payment.  Upon such payment of liquidated damages and all
     other Rent then due and payable by Lessee hereunder (excluding the SLV
     Excess and any Scheduled Rent designated as "advance rent" on Schedule A
     hereto with respect to the Casualty Payment Date referred to above), Lessor
     shall transfer the Transponders (without any representation, recourse or
     warranty whatsoever, other than the absence of Lessor Liens or Owner
     Participant Liens) to Lessee and Lessor shall execute and deliver such
     documents evidencing such transfer as Lessee shall reasonably request, and
     Lessee shall indemnify Lessor on an After-Tax Basis for Lessor's reasonable
     expenses incurred in connection with such transfer; and/or

               (c) Lessor or its agent may sell the Transponders at public or
     private sale, as Lessor may determine, or otherwise may dispose of, hold,
     use, operate, keep idle, lease (whether for a period greater or less than
     the balance of what would have been the Basic Term or any Renewal Term, as
     the case may be) to others (subject to Section 6(d)) the Transponders, all
     on such terms and conditions and at such place or places as Lessor may
     determine and all free and clear of any rights of Lessee and of any claim
     of Lessee, in equity, at law or by statute (including, without limitation,
     any right or claim of Lessee that shall arise or shall have arisen in
     connection with Lessee's making or having made the EBO Prepayment), whether
     for loss or damage or otherwise and Lessee shall use its best efforts to
     obtain or assist Lessor in obtaining, any necessary regulatory approvals
     for Lessor to take any action pursuant to this Section 16(II)(c); provided,
                                                                       -------- 
     however, that if Lessor or its agent shall sell any Transponder, Lessee's
     -------                                                                  
     obligation to pay Base Rent with respect to such Transponder sold hereunder
     for any period after the date of such sale (or if such date is not a
     Casualty Payment Date, the next succeeding Casualty Payment Date) shall
     terminate and such Transponder shall cease to be subject to this Lease from
     and after the date of such sale.  In addition, Lessee's obligation to pay
     Base Rent for any period after Lessee shall have been deprived of control
     of the Transponder pursuant to this Section 16(II)(c) shall be reduced by
     the net proceeds, if any, received by Lessor from leasing the Transponder
     to, or otherwise permitting its use by, any Person (including pursuant to
     the GLA Sublease) other than Lessee fairly attributable to all or any
     portion of such period.  In the event Lessor shall have sold any
     Transponder pursuant to this Section 16(II)(c) (and prior thereto shall not
     have exercised its rights under Section 16(II)(d)(X) hereof), Lessor may
     demand that Lessee pay to Lessor, and Lessee shall pay to Lessor, as
     liquidated damages for the loss of a bargain and not as a penalty, in lieu
     of any further payments of Base Rent for any period after the date on which
     such sale occurs (or if such date is not a Casualty Payment Date, the next
     succeeding Casualty Payment Date), an amount equal to the sum of the
     following amounts calculated as of the date on which the sale occurs (or,
     if such date is not a Casualty Payment

     Date, the next succeeding Casualty Payment Date):  (A) all unpaid Base Rent
     due on or before such Casualty Payment Date with respect to such
     Transponder, if any, and (B) the amount, if any, by which the Stipulated
     Loss Value for such Transponder exceeds the net proceeds of such sale
     (together with interest, if any, at the Overdue Rate on the amounts
     described in (A) and (B) above from the Casualty Payment Date as of which
     such amounts were calculated until the date of actual payment); provided,
                                                                     -------- 
     however, that in the event that Lessee shall have theretofore made the EBO
     -------                                                                   
     Prepayment, Lessor shall pay to Lessee an amount equal to the EBO Amount
     less such excess; and/or

               (d)(X) Whether or not Lessor shall have exercised, or shall
     thereafter at any time exercise, any of its remedies under Section
     16(II)(c) hereof (other than a sale under Section 16(II)(c) hereof), Lessor
     may, at any time prior to the time that any Transponder shall have been
     sold or leased by Lessor pursuant to Sections 16(II)(b) or 16(II)(c)
     hereof, by written notice to Lessee requesting that the Fair Market Sales
     Value or Fair Market Rental Value of such Transponder be determined, demand
     that Lessee pay to Lessor, and Lessee shall pay to Lessor, on the first
     Casualty Payment Date occurring at least ten (10) days after the
     determination of such Fair Market Sales Value or Fair Market Rental Value,
     as the case may be (the "Relevant Date"), each determined on an as is,
                              -------------                                
     where is basis, as liquidated damages for loss of a bargain and not as a
     penalty (in lieu of any further payments of Base Rent with respect to such
     Transponder for any period after the Relevant Date), an amount equal to the
     sum of (A) all unpaid Base Rent due on or before such Relevant Date with
     respect to such Transponder, if any, and (B) whichever of the following
     amounts Lessor, in its sole discretion, shall specify in such notice
     (together with interest on such amount at the Overdue Rate from the
     Relevant Date to the date of actual payment):  (x) an amount equal to the
     excess, if any, of the Stipulated Loss Value, computed as of such Relevant
     Date, over the Fair Market Rental Value of such Transponder, valued on an
     as is, where is basis as of the Relevant Date for the remainder of the
     Interim Term and the Basic Term or the remainder of the Renewal Term, as
     the case may be, after discounting such Fair Market Rental Value semi-
     annually (effective on the Rent Payment Dates) to present value as of the
     Relevant Date at the rate of interest equal to the Overdue Rate; (y) an
     amount equal to the excess, if any, of such Stipulated Loss Value computed
     as of such Relevant Date, over the Fair Market Sales Value of such
     Transponder valued on an as is, where is basis as of the Relevant Date or
     (z) an amount equal to the excess, if any, of (1) the present value
     computed as of such Relevant Date of all installments of Scheduled Rent for
     the remainder of the Interim Term and Basic Term or Base Rent for the
     remainder of the Renewal Term, as the case may be, discounted semi-annually
     (effective on the Rent Payment Dates) to present value as of the Relevant
     Date at the rate of interest equal to the Overdue Rate over (2) the present
     value, computed as of such Relevant Date, of the Fair Market Rental Value
     of the Transponder valued on an as is, where is basis as of the Relevant
     Date for the remainder of the Interim Term and the Basic Term or the
     remainder of the Renewal Term, as the case may be, discounted semi-annually
     (effective on the Rent Payment Dates) to present value as of the Relevant
     Date at the rate of interest equal to the Overdue Rate; provided, however,
                                                             --------  ------- 
     that, in the event that Lessee shall have theretofore made the EBO
     Prepayment, Lessor shall pay to Lessee an amount equal to the EBO Amount
     less the applicable excess, if any, referred to in clause (x), (y) or (z)
     above; and/or

               (Y)  Lessor may exercise any other right or remedy available to
     it under Applicable Law, except for and subject to the limitations and
     restrictions (including with respect to damages, rights and remedies) in
     favor of Lessee in this Lease, any other Operative Document

                                      28

     or any Hughes Agreement, and subject to the parties' intent that Lessor's
     recovery shall in no event exceed that set forth in the preceding clauses
     (b), (c) and (d)(X) of this Section 16.

               (e) For all purposes of this Section 16, in the event that there
     is a portion of the Scheduled Rent on any Casualty Payment Date that is
     designated as "arrears rent" on Schedule A and there is also a portion that
     is designated as "advance rent", a portion of the Rent Differential Amount
     with respect to such Casualty Payment Date shall be added to the Scheduled
     Rent designated as an "arrears rent" due on such date and the remainder of
     such Rent Differential Amount shall be taken into account in the
     computation of Stipulated Loss Value pursuant to the definition of
     Stipulated Loss Value.  It is intended that the entire amount of the Rent
     Differential Amount due on such Casualty Payment Date shall be allocated
     between the Scheduled Rent designated as an "arrears rent" due on such date
     and the computation of Stipulated Loss Value, as appropriate and without
     duplication, in such manner as will preserve the Owner Participant's Net
     Economic Return and comply with the minimum payment requirement (it being
     understood that the entire amount of such Rent Differential Amount shall be
     taken into consideration in making such allocation).

All determinations of Fair Market Sales Value and Fair Market Rental Value
pursuant to this Section 16 shall be determined pursuant to the Appraisal
Procedure.  No termination of this Lease, in whole or in part, or exercise of
any remedy under this Section 16 shall, except as specifically provided herein,
relieve Lessee of any of its liabilities and obligations hereunder, all of which
shall survive such termination, repossession or exercise of remedy.  In
addition, Lessee shall be liable for any and all unpaid Supplemental Rent due
hereunder before, after or during the exercise of any of the foregoing remedies,
including all reasonable legal fees and other costs and expenses reasonably
incurred by Lessor, Owner Participant or Agent by reason of the occurrence of
any Event of Default or the exercise of Lessor's remedies with respect thereto.
At any sale of the Transponders or any part thereof pursuant to this Section 16,
Lessor, Owner Participant or Agent may bid for and purchase such property.

          Notwithstanding any provision in this Lease or any other Operative
Document, Lessee shall not cease to have the legal right to access any of the
Transponders unless and until Lessor shall give Lessee and Seller, at the time
when a notice of termination is given under the first sentence of clause (II)
above, 24 hours notice expressly demanding that Lessee surrender such right.

          To the extent permitted by, and subject to the mandatory requirements
of, Applicable Law, and except as otherwise specifically provided for in this
Lease, each and every right, power and remedy herein specifically given to
Lessor or otherwise in this Lease shall be cumulative and shall be in addition
to every other right, power and remedy herein specifically given or now or
hereafter existing at law, in equity or by statute, and each and every right,
power and remedy whether specifically herein given or otherwise existing may be
exercised from time to time and as often and in such order as may be deemed
expedient by Lessor, and the exercise or the beginning of the exercise of any
power or remedy shall not be construed to be a waiver of the right to exercise
at the same time or thereafter any other right, power or remedy.  No delay or
omission by Lessor in the exercise of any right, remedy or power or in the
pursuit of any remedy shall impair any such right, remedy or power or be
construed to be a waiver of any default on the part of Lessee or to be an
acquiescence therein.  No express or implied waiver by Lessor of any Event of
Default shall in any way be, or be construed to be, a waiver of any future or
subsequent Event of Default.

          Except to the extent provided for by the express terms of this Lease,
each of Lessor and Agent and any Person claiming through either of them, waives
and agrees not to claim any amount under this Section 16 or otherwise under this
Lease in respect of incidental or consequential damages incurred by it.

          To the extent permitted by Applicable Laws, Lessee hereby waives any
rights now or hereafter conferred by statute or otherwise that may require
Lessor, its successors or assigns to mitigate its damages in any particular
manner or that may otherwise limit or modify any of the rights or remedies of
Lessor under this Section 16, but nothing contained herein shall eliminate
Lessor's obligation to mitigate its damages as may be required by Applicable
Law.

     SECTION 17.  Right to Perform for Lessee.
                  --------------------------- 

              (a) Right to Cure.  If Lessee shall fail to make any payment of 
                  -------------    
Rent to be made by it hereunder or shall fail to perform or comply with any of
its other agreements contained herein or in the Hughes Agreements relating to
any of the Transponders, Lessor or Owner Participant may (but shall not have any
duty to do so) itself make such payment or perform or comply with such
agreement; provided that nothing contained in this Section 17(a) shall be deemed
to expand in any way the rights of Lessor or Owner Participant under Section
16.1 of the Loan Agreement. The amount of any such payment and the amount of the
reasonable expenses of Lessor and Owner Participant incurred in connection with
such payment or the performance of or compliance with such agreement, as the
case may be, together with interest thereon at the Overdue Rate, shall be deemed
Supplemental Rent, payable by Lessee upon demand.

              (b) Lessor is Lessee's Agent and Attorney.  Without in any way
                  -------------------------------------                     
limiting the obligations of Lessee or Lessor hereunder, Lessee hereby
irrevocably appoints Lessor as its agent and attorney-in-fact hereunder, with
full power and authority at any time at which Lessee is obligated to deliver any
Transponder to Lessor, to demand and take such Transponder in the name and on
behalf of Lessee from whosoever shall be at the time in control thereof.

     SECTION 18.  Renewal.
                  ------- 

              (a) Notice of Renewal or Purchase.  Not more than 720 nor less 
                  -----------------------------   
than 540 days prior to the expiration of the Basic Term, but in no event before
Lessee shall have received the Subsequent Appraisal (provided Lessee ordered it
as provided in Section 20(c), below) (the "Preliminary Notice Expiration Date"),
                                           ----------------------------------   
Lessee shall give Lessor notice (the "Preliminary Notice") of Lessee's
                                      ------------------              
irrevocable intention to either purchase pursuant to Section 19(a)(i), or renew
the Lease pursuant to Section 18(b) in respect of, all but not less than all of
the Transponders.

          If Lessee gives the Preliminary Notice, then not less than one hundred
eighty (180) days before the expiration of the Basic Term with respect to a
purchase of Transponders or renewal of the Lease or one hundred eighty (180)
days prior to the end of the Renewal Term with respect to a purchase of
Transponders (the "Final Notice Expiration Date"), Lessee shall give Lessor
                   ----------------------------                            
notice of its irrevocable election (the "Final Notice") of one of the following
                                         ------------                          
options:  (i) to renew this Lease at the end of the Basic Term pursuant to
Section 18(b) for the Renewal Term or (ii) to purchase the Transponders pursuant
to Section 19(a)(i) at the end of the Basic Term or of the Renewal Term.

                                      30
<PAGE>
 
          If Lessee shall fail timely to deliver the Preliminary Notice, then
Lessee shall be deemed not to have elected to renew this Lease or purchase the
Transponders, and promptly thereafter, but in any case within 30 days after the
Preliminary Notice Expiration Date, shall provide Lessor with the names, last
known business addresses and telephone numbers of the Persons using any
Transponders pursuant to a Use Agreement (not including any Occasional Use
Service Contract).  If Lessee shall fail to deliver the Final Notice as required
above after having delivered the Preliminary Notice, Lessee shall be deemed to
have elected to purchase the Transponders pursuant to Section 19(a)(i).  The
notice requirements of this Section 18(a) shall not apply to Lessee's right to
purchase any Transponders pursuant to Sections 19(a)(ii) through 19(a)(iv).

          (b) Fair Market Value Renewal Option.  If Lessee delivers the Final
              --------------------------------                               
Notice set forth in Section 18(a), above, stating that it will renew the Lease
in respect of the Transponders, and so long as no Bankruptcy Default or Event of
Default has occurred and is continuing at the end of the Basic Term, then this
Lease shall be renewed with respect to the Transponders at a Base Rent equal to
the Fair Market Rental Value of the Transponders (as determined pursuant to the
Subsequent Appraisal) and payable in accordance with Section 18(c), below.  The
Renewal Term shall be for the period beginning immediately upon the expiration
of the Basic Term and, unless earlier terminated pursuant to the terms of this
Agreement, ending on the earliest of the last day of the useful commercial life
of the Satellite (as determined pursuant to the Subsequent Appraisal), the date
specified by the Lessee in the Final Notice and the date on which the Satellite
is disposed of pursuant to Section 12.1.1 of the Purchase Agreement.  At the end
of the Basic Term, if Lessee has timely elected to renew this Lease with respect
to the Transponders, then the terms and conditions of this Lease with respect to
the Transponders shall continue in full force and effect during the Renewal
Term, except that (x) Lessee shall pay Lessor Base Rent for the Transponders in
the amount of the Fair Market Rental Value thereof as determined by the
Subsequent Appraisal and (y) the Stipulated Loss Values and Termination Values
applicable during such Renewal Term shall initially be the Fair Market Sales
Value (determined pursuant to such Subsequent Appraisal) of the Transponders as
of the commencement of the Renewal Term and, on each Casualty Payment Date
during the Renewal Term, shall decline on a straight line basis by an amount per
Casualty Payment Date obtained by dividing (A) the difference between the Fair
Market Sales Value of the Transponders as of the beginning of the Renewal Term
and the estimated Fair Market Sales Value of the Transponders as of the end of
the Renewal Term by (B) the number of months in such Renewal Term.

          (c) Renewal Rent.  At the end of the Basic Term, if Lessee shall have
              ------------                                                     
timely elected to renew this Lease as aforesaid and if no Bankruptcy Default or
Event of Default shall then exist and be continuing, Lessee and Lessor shall
execute a lease supplement hereto in form and substance reasonably satisfactory
to Lessor and Lessee to evidence such renewal.  Such lease supplement shall
provide for the semi-annual (or shorter period if necessary in case of the last
Lease Period) payment of Base Rent for the Renewal Term, with a final
installment on the last day of the Renewal Term, payable in each case in
arrears, in accordance with the aforesaid determinations of Base Rent and shall
provide for Stipulated Loss and Termination Values for the Transponders covered
thereby with respect to the Renewal Term determined as aforesaid.  The
installments of Base Rent during the Renewal Term shall be equal in amount
(except for the last such installment which shall be pro rated, if necessary,
for a Lease Period which is shorter than six months).  All other terms of the
Operative Documents and the Hughes Agreements shall continue in effect during
each such Renewal Term in accordance with the provisions thereof and to the
extent provided therein, except as otherwise expressly provided in this Lease.

     SECTION 19.  Purchase Options.
                  ---------------- 

              (a) Purchase Option Events.  So long as no Bankruptcy Default or 
                  ----------------------          
any Event of Default has occurred and is continuing, Lessee shall have the right
to purchase:

                  (i) all but not less than all of the Transponders, if Lessee
     timely delivers or is deemed to have delivered the Final Notice
     contemplated by clause (ii) of the second paragraph of Section 18(a)
     (stating that it will purchase the Transponders), on the expiration date of
     the Basic Term or the Renewal Term, as applicable, at a purchase price
     equal to the Fair Market Sales Value of the Transponders as of such date as
     determined pursuant to the Subsequent Appraisal;

                  (ii) all (but not less than all) of the Transponders on the
     EBO Date at a purchase price equal to the EBO Amount therefor;

                 (iii) if Owner Participant has become a Competitor and fails to
     transfer all of its right, title and interest in and to the Lessor's Estate
     and the Operative Documents in accordance with Article XIV of the
     Participation Agreement within three (3) months after the Owner Participant
     has become a Competitor, all (but not less than all) of the Transponders on
     any Rent Payment Date, at a purchase price equal to the greater of (A) the
     Termination Value for such Transponders as of such Rent Payment Date and
     (B) the Fair Market Sales Value of such Transponders as of such Rent
     Payment Date, as determined by an appraisal obtained in accordance with
     Section 19(b)(ii); and

               (iv) if the aggregate of all Rental Adjustments, if any, under
     the Lease, which occur after the Commencement Date, when combined with all
     Rental Adjustments made on or prior to the Commencement Date pursuant to
     the Participation Agreement, shall result in (A) an increase in the present
     value of Scheduled Rent with respect to the Transponders (expressed as a
     percentage of Lessor's Cost) either on a full term basis or through the EBO
     Date including the EBO Amount (discounted in each case to the Commencement
     Date at the Discount Rate), as compared to the analogous present value set
     forth on Item 7 or Item 8 to Schedule E hereto, and, as a result thereof,
                                  ----------                                  
     in the judgment of Lessee, the lease transaction contemplated herein shall
     be economically disadvantageous to the Lessee as compared to a medium term
     financing or (B) the Lease not qualifying as an Operating Lease for Lessee,
     then Lessee shall have the right to purchase all (but not less than all) of
     ----                                                                       
     the Transponders on any Rent Payment Date at a price equal to the higher of
     (i) the Fair Market Sales Value of the Transponders on such Rent Payment
     Date (offset, in the event such Fair Market Sales Value is greater than the
     Fair Market Sales Value set forth in the Commencement Date Appraisal, by an
     amount equal to the excess of (y) the actual Fair Market Sales Value of the
     Transponders on the Commencement Date, as determined by an appraisal
     obtained in accordance with Section 19(b)(ii), which appraisal shall take
     into consideration all factors and conditions existing on the Commencement
     Date that were not taken into account in the determination of Fair Market
     Sales Value set forth in the Commencement Date Appraisal over (z) Lessor's
     Cost for the Transponders set forth in the Commencement Date Appraisal) or
     (ii) the Termination Value of the Transponders on such Rent Payment Date.

          (b) Notice of Election; Manner of Purchase; Transfer After Purchase.
              --------------------------------------------------------------- 

               (i) (1)  In order to exercise its right to purchase the
     Transponders pursuant to Section 19(a)(ii), Lessee shall, at least ninety
     (90) (but not more than 360) days prior to the EBO Date, give irrevocable
     notice to Lessor in writing stating that Lessee will purchase the
     Transponders pursuant to Section 19(a)(ii).  (2) In order to exercise its
     right to purchase the Transponders pursuant to Section 19(a)(iii), Lessee
     shall give tentative notice to Lessor in writing within 90 days after (A)
     Owner Participant shall have confirmed to Lessee pursuant to Section
     5.02(h) of the Participation Agreement that it is a Competitor, or (B)
     Lessee shall have notified Owner Participant that Owner Participant has
     become a Competitor, and Owner Participant shall have become a Competitor,
     whichever of (A) or (B) shall first occur.  (3) In order to exercise its
     right to purchase the Transponders pursuant to Section 19(a)(iv), Lessee
     shall give tentative notice to Lessor in writing within forty-five (45)
     days after making the determination pursuant to Section 19(a)(iv).  For so
     long as the Loan Agreement shall be in effect, Lessee shall provide Agent
     with a courtesy copy of each notice given Lessor pursuant to this clause
     (b)(i), provided such notices shall have no legal effect under Section 2.10
     of the Loan Agreement.

               (ii) In the case of any tentative or irrevocable notice pursuant
     to Sections 19(b)(i)(2) or 19(b)(i)(3), Lessee shall further specify that
     it desires to obtain an appraisal of the Fair Market Sales Value of the
     Transponder(s) as of the Rent Payment Date (which Rent Payment Date shall
     be the next succeeding Rent Payment Date no earlier than 30 days following
     the date of such tentative notice) or other permitted date specified in
     such notice, as applicable.  Promptly after Lessee shall have given such
     notice, such Fair Market Sales Value shall be determined pursuant to the
     Appraisal Procedure (provided that the timetable for the Appraisal
     Procedure shall be appropriately accelerated to meet the deadlines set
     forth in the next sentence, so long as notwithstanding such acceleration,
     the appraiser shall have adequate time to make a considered determination).
     Lessee shall give irrevocable notice to Lessor not later than ten (10)
     Business Days after the completion of the Appraisal Procedure if it desires
     to consummate the purchase of the Transponders pursuant to Sections
     19(a)(iii) or 19(a)(iv), but in no event later than fifteen (15) days prior
     to the Rent Payment Date or other permitted date specified in the tentative
     notice referred to in this Section 19(b)(ii), which Rent Payment Date shall
     be the next succeeding Rent Payment Date no earlier than 30 days following
     the date of such tentative notice.

               (iii)  Subject to Section 19(b)(iv), on the date of purchase,
     Lessee shall pay the purchase price for the Transponders, together with (A)
     all unpaid Base Rent due on or before such date of purchase with respect to
     the Transponders, if any, and (B) any other Rent due and unpaid as of the
     date of such purchase (excluding the relevant amount specified in Section
     19(a) and any Scheduled Rent designated as "advance rent" on Schedule A
     hereto with respect to the date of such purchase).  Upon receipt of the
     payments set forth in the preceding sentence, Lessor shall transfer all
     right, title and interest of Lessor in and to the applicable Transponders,
     as is and where is, to Lessee, free and clear of Lessor Liens and Owner
     Participant Liens, but otherwise without warranty, and Lessor shall execute
     and deliver to Lessee, at Lessee's reasonable expense, a bill of sale or
     assignment and such other instruments, documents and opinions as Lessee may
     reasonably request to evidence the valid consummation of such transfer and
     shall take such actions under Section 9.12 of the Loan Agreement as Lessee
     may reasonably request.

<PAGE>
 
               (iv)  Subject to Section 19(a), if Lessee shall provide the
     irrevocable notice pursuant to Section 19(b)(i)(1) to purchase the
     Transponders on the EBO Date, then Lessee may, at its option, pay the EBO
     Amount therefor on a date not earlier than the same calendar day in the
     fourth month prior to the EBO Date (e.g., if the EBO Date is July 2, 1999,
                                         ----                                  
     not earlier than March 2, 1999), but in any event such payment must occur
     within the same taxable year of the Owner Participant as the EBO Date shall
     occur (the "EBO Prepayment"), and shall pay all other amounts pursuant to
                 --------------                                               
     Section 19(b)(iii) due and owing as of the EBO Date on the EBO Date, and,
     upon receipt of all such amounts, Lessor shall on the EBO Date comply with
     the last sentence of Section 19(b)(iii).  If Lessee shall make the EBO
     Prepayment pursuant to the immediately preceding sentence, then (i) from
     and after the making of the EBO Prepayment, the Stipulated Loss Value for
     each Transponder for all purposes in this Lease shall be reduced by an
     amount equal to the prepaid EBO Amount therefor, except that Stipulated
     Loss Value, as used in Section 16 hereof shall not be so reduced, except as
     provided therein, (ii) upon request of Lessee, if the Lien of the Loan
     Agreement shall have been fully discharged, Lessor shall grant to Lessee a
     security interest in the Transponders, securing Lessor's obligation to
     comply with the last sentence of Section 19(b)(iii), subject to receipt of
     the payment specified in Section 19(b)(iii) on the EBO Date, subject to and
     as provided in Section 19(b)(iii), and Lessee shall pay all reasonable
     expenses in connection with the granting of such security interest as
     Supplemental Rent on an After-Tax Basis.

          (c) Assumption of Notes.  Notwithstanding the provisions of Sections
              -------------------                                             
19(a) and (b) and subject to compliance with Section 2.20 of the Loan Agreement,
in connection with a purchase by Lessee of the Transponders pursuant to any of
Sections 19(a)(ii) through 19(a)(iv) or a transfer pursuant to Section 8(a)(i),
as the case may be, at Lessee's option, the Applicable Principal Amount of the
Notes may be Assumed by Lessee pursuant to Sections 5.05(a) and 11.03 of the
Participation Agreement.  Once Lessee has elected to exercise its option to
Assume the Notes by giving notice of such election in its notice given pursuant
to Section 19(b) hereof, such Notes shall be mandatorily Assumed by Lessee in
accordance with Section 2.20 of the Loan Agreement.  The obligation of Lessee to
pay the purchase price pursuant to the applicable clause of Section 19(a) or
Lessee's election to Assume the Notes in connection with a transfer pursuant to
Section 8(a)(i) shall be satisfied by such Assumption of the Notes to the extent
of the principal amount of the Notes so assumed (after payment of Base Rent, if
any, due on or before the date of purchase), by complying with the applicable
provisions of the Lease, the Participation Agreement and the Loan Agreement and
by taking all such other acts as are reasonably necessary to permit such
Assumption by Lessee.

          (d) No Duplication of Rent Differential Amount.  In the event that
              ------------------------------------------                    
there is a portion of the Scheduled Rent on any date of purchase that is
designated as "arrears rent" on Schedule A and there is also a portion that is
designated as "advance rent", a portion of the Rent Differential Amount with
respect to such date of purchase shall be added to the Scheduled Rent designated
as an "arrears rent" due on such date and the remainder of such Rent
Differential Amount shall be taken into account in the computation of the EBO
Amount or the computation of Termination Value, as appropriate.  It is intended
that the entire amount of the Rent Differential Amount due on such date of
purchase shall be allocated between the Scheduled Rent designated as an "arrears
rent" due on such date and the computation of the EBO Amount or the Termination
Value, as appropriate and without duplication, in such manner as will preserve
the Owner Participant's Net Economic Return and comply with the minimum payment
requirement (it being understood that the entire amount of such Rent
Differential Amount shall be taken into consideration in making such
allocation).

     SECTION 20.  Further Assurances; Default Notice.
                  ---------------------------------- 

              (a) Further Assurances.  Lessee, at its reasonable expense, shall
                  ------------------                                           
promptly and duly execute and deliver to Lessor, Owner Participant and Agent
such documents and assurances and take such further action as Lessor (or Agent)
may from time to time reasonably request in order to carry out more effectively
the intent and purpose of this Lease, the other Operative Documents and the
Hughes Agreements and to establish and protect the rights and remedies created
or intended to be created in favor of Lessor hereunder and thereunder, to
establish, perfect (to the extent practicable, in the case of the Transponders),
and maintain Lessor's right, title and interest in and to the Transponders and
the Collateral Security and, for the benefit of Agent, the lien and security
interest in the Collateral Security provided for in the Loan Agreement, subject
to no Lien other than Permitted Liens, including, without limitation, if
requested by Lessor, Owner Participant or Agent, at the expense of Lessee, the
recording or filing of appropriate memoranda hereof, or of such financing
statements or other documents with respect hereto as any of Lessor, Owner
Participant or Agent may from time to time reasonably request, and Lessor agrees
promptly to execute and deliver such of the foregoing financing statements or
other documents as may require execution by Lessor and to the extent permitted
by Applicable Laws, Lessee hereby authorizes any such financing statements to be
filed without the necessity of signature by Lessee; provided, however, no
                                                    --------  -------    
counterparts hereof shall be filed, unless Lessor or Agent shall determine that
it is advisable, in the reasonable opinion of the counsel of Lessor or Agent, as
the case may be, to file such counterpart in order to protect its interest under
this Lease; then, upon 30 days' prior notice and delivery to Lessee of such
opinion of counsel of Lessor or Agent, as the case may be, Lessor or Agent, as
the case may be, may file such counterpart.

              (b) Notice of Default.  Promptly after obtaining Actual 
                  -----------------      
Knowledge of the occurrence or existence of any Default or Event of Default,
Lessee shall so notify Lessor (and Agent) and set forth in reasonable detail the
circumstances surrounding such Default or Event of Default and shall specify
what actions Lessee has taken or intends to take to cure such Default or Event
of Default.

              (c) Subsequent Appraisal.  No earlier than 760 days and no later 
                  --------------------     
than 720 days prior to the end of the Basic Term, Lessee shall have the option
to initiate the Appraisal Procedure, and at Lessee's cost and expense, to cause
an appraisal of the Transponders to determine, as appropriate, the remaining
useful commercial life and residual value of the Transponders, the Fair Market
Sales Value of the Transponders as of the end of the Basic Term and as of the
end of the Renewal Term, and the Fair Market Rental Value of the Transponders as
of the end of the Basic Term. Any appraisal pursuant to this Section 20(c) is
herein referred to as a "Subsequent Appraisal."

obligations secured by the Loan Agreement, Lessor provides in the Loan
Agreement, among other things, for the assignment (to the extent provided
therein) by Lessor to Agent of all of Lessor's right, title and interest to this

the benefit of the Noteholders in and to the Collateral Security as described in
the Granting Clause of the Loan Agreement.  Lessee hereby (a) consents to such
assignment pursuant to the terms of the Loan Agreement, and (b) agrees to pay
directly to Agent for so long as the Lien of the Loan Agreement shall remain in

such Person expressly stated in any Operative Document or Hughes Agreement or
for equitable relief to obtain compliance with any such obligation, or for the
return of mistakenly paid amounts of any Rent or from exercising the rights set
forth in Section 3(h) hereof, or (y) be construed as:  (1) a guaranty of (i) the
value of the Transponders upon termination of the Basic Term or any Renewal Term
or (ii) the useful life of the Transponders or (iii) payment of any of the
Notes; or (2) a prohibition of assertion of any claim against any manufacturer,
supplier, dealer, vendor, contractor, subcontractor or installer with respect to
the Transponders; or (3) a waiver by Lessee of its right to assert and sue upon
any claims it may have against any other Person in one or more separate actions)

become due to or for the account of Lessor and payable by Lessee hereunder or
under any other Operative Document or Hughes Agreement to which Lessee in any
capacity is a party which have been assigned or required to be assigned to Agent
pursuant to the Loan Agreement or this Agreement.  Lessee acknowledges that, so
long as any Notes are outstanding, all rights of Lessor under this Lease shall
be exercised only by Agent, as assignee of Lessor's rights under this Lease
pursuant to the Loan Agreement, subject, however, to Sections 13.1 and 16.4 of
the Loan Agreement and subject to Lessor's rights in respect of Excepted
Payments.

pursuant to Section 5(b)(ii) and (iii) of this Agreement or than the Lessor
otherwise has under this Lease.

effect in any applicable jurisdiction), no security interest in this Lease may
be created through the transfer or possession of any counterpart hereof other
than the original executed counterpart which shall be identified as the

Subject:   Galaxy XI Spacecraft Authorization 

Reference: HCG Letter FDS-96-06-08-001 dated 10 June 1996

Dear Faye,

Hughes Space and Communications hereby acknowledges receipt of the referenced 
letter providing authorized funding of ***** for design activities and long lead
part procurement for a Galaxy XI spacecraft.

HCI's authorization identifies terms and conditions.  The terms and conditions 
for Galaxy XI are subject to negotiation, and are not the basis of our 
proceeding with advanced efforts on Galaxy XI.  The Galaxy X terms identified in
the transmittal to you on 24 May 1996, can be considered the basis of our
proceeding on Galaxy XI. Please note that at that time the Liquidated Damages
provisions had not been agreed to. The basis of proceeding using the Galaxy XI
authorization does not include Liquidated Damages or any consequences for late
delivery.

Contingent upon the above, attached is the signed acceptance of the total of 
**** of funding for design activities and long lead part procurements.

We are available to discuss this subject in greater detail, if it would be 
helpful to you. Please do not hesitate to call me at 364-5570 or Tom Mattis at 
364-8127.

Very truly yours,

/s/ Christine Kung

ARTICLE 5.     PRICE

     5.1  The total price (the "Contract Price") for Contractor to provide the
          Spacecraft, Documentation and Related Services as defined in Article 3
          herein is *************************************. This price shall be
          paid in accordance with Paragraph 6.2 of Article 6 entitled
          "Payments." However, ********************************* of this
          Contract Price shall be at risk ("Risk Sum") in accordance with
          Paragraph 5.2 below.

     5.2  In the event that:

          (i)   the Launch Date ("Risk Date"), as defined in Paragraph 7.1.2 of
                Article 7, is delayed due primarily to the fault of the
                Contractor by its actions or inactions (and not the Launch
                Vehicle Provider and/or HCG);

          (ii)  such actions or inactions of the Contractor cause an actual
                delay in the launch of the Spacecraft; and

          (iii) the delay is not excusable in accordance with Article 12 of this
                Contract;

          then *************************************************************
          *****************************************************************
          **********************************************. The applicability of
          this Paragraph 5.2 shall be determined no earlier than twenty-four
          hours after the Risk Date. The Buyer shall be required to pay the Risk
          Sum for a Satellite which is timely delivered for purposes of storage
          unless such storage is required due to any delay described in the
          first sentence of this Paragraph 5.2; provided, however, that if Buyer
          directs that the Spacecraft be delivered into storage for Buyer's
          convenience, then the Risk Date shall be extended to a revised date
          established by the Parties. In the event of any delay described in the
          first sentence of this Paragraph 5.2, then Buyer's rights and remedies
          in Article 11 and Article 5 shall both apply.

     6.4  Payment Schedule Revision: The payment plan established in Paragraph
          ------------------------- 
          6.3 above is based upon an April 1998 launch date. If the launch date
          established in accordance with Article 7, Paragraph 7.1.2 is later
          than April 1998, the payment plan in Paragraph 6.3 of this Article
          shall be revised by mutual agreement of the Parties to reflect the
          established Launch Date.

     6.5  HSC shall not be obligated to deliver the Spacecraft to the Launch
          Site if there are any outstanding Delinquent Payments owed by HCG to
          HSC under this contract one month prior to shipment of the Spacecraft
          from the HSC facility. "Delinquent Payments" are defined as those
          payments not received by HSC within thirty (30) days of the dates due
          as defined in Paragraph 6.5.2 below. Once HCG has paid HSC for any
          "Delinquent Payments" and any interest accrued in accordance with
          Paragraph 6.7 below, HSC shall use its reasonable best efforts to ship
          the Spacecraft to the Launch Site so as to enable launch on the
          scheduled Launch Date and in any event to make shipment as soon as
          practicable and no later than sixteen (16) weeks after payment by HCG
          of such Delinquent Payments. HCG will be responsible for and will pay
          to HSC any reasonable costs and *** profit on such costs that HSC may
          incur as a result of a delay in delivery due to HCG's Delinquent
          Payments. Notwithstanding the foregoing, this Section 6.5 shall not
          relieve Contractor of its obligation to deliver the Spacecraft, and no
          "Delinquent Payment" shall be deemed to have occurred, due to any non-
          payment by HCG on account of an alleged breach by Contractor or other
          dispute as to such payment. In such event, HCG shall, within thirty
          (30) days of the date such payment is due, pay the full amount of such
          payment into an interest-bearing escrow account to be established at
          Bank of America, Concord, California. Upon settlement of the dispute
          as to such payment and alleged breach in accordance with Article 32,
          the Party entitled to the amount in escrow shall receive such amount
          together with all accrued interest thereon and the other Party shall
          pay all costs and fees associated with the escrow of such amount.

          In the event of a failure by the Buyer or the Contractor to make a

          provided hereunder shall take place in accordance with the terms of
          Article 10, entitled "Access to Work in Process," herein.

     9.2  Preliminary Acceptance of the Spacecraft shall occur when all in-plant
          tests required to be performed by Contractor for the Hardware have
          been completed and the Contractor has demonstrated at the pre-ship
          review that the Hardware meets the requirements of Exhibit B and D, at
          which time HCG shall accept the Hardware on a Preliminary basis in

          Site tests specified in Exhibit C, Galaxy X Spacecraft Integration
          Test Plan. If the Hardware is unacceptable, Contractor shall promptly
          and at its expense, rectify the unsatisfactory Hardware and resubmit
          the Hardware for acceptance by HCG as provided above. In either case,
          the Hardware shall be deemed accepted upon failure of HCG to notify
          Contractor in writing within the above five (5) business days that it
          is accepted, rejected or that in HCG's opinion further corrective
          action must be taken by the Contractor.

     9.3  Final Acceptance of the Spacecraft shall occur upon the earliest of i)
          the completion of In-orbit Testing in accordance with Exhibit A, ii)
          fifty (50) days after Intentional Ignition (as defined in Article 15,
          Paragraph 15.2 of this Contract) or iii) immediately before a Partial
          Failure, Total Failure or Total Constructive Failure (as each such
          term is defined in the applicable Hughes Communications Galaxy Launch
          Insurance Contract or successor contract), which occurs at or after
          Intentional Ignition. HCG shall have access to Launch Site test
          results during the launch campaign in accordance with the provisions
          of Article 10, Paragraph 10.1 "Access to Work in Process."

     9.4  With respect to deliverable Hardware which HCG orders Contractor to
          store, the Hardware shall be stored at a location to be negotiated and
          Final Acceptance shall occur at the end of the ************ warranty
          period as set forth in Article 15 herein, entitled "Spacecraft
          Warranty," or such other event mutually agreed upon between the
          Parties.

ARTICLE 12.  EXCUSABLE DELAYS

     12.1 If either Party or a subcontractor of either Party is delayed by act
          of God, or of the public enemy, fire, flood, earthquake, epidemic,
          quarantine restriction, strike, walkout, freight embargo, or any other
          event which is beyond their control or does not arise from the acts or
          omissions of either Party or its respective subcontractors, said delay
          shall constitute an excusable delay ("Force Majeure Events"). In the
          event of an excusable delay, there shall be an equitable adjustment to
          the time of delivery and/or performance stated in this Contract. The
          affected Party shall give notice in writing to the other Party within
          10 working days that an excusable delay condition exists after
          learning of such delay. Such notification shall include the cause of
          the excusable delay, the expected length of the excusable delay, and
          alternate plans to mitigate the effect of the excusable delay.

     12.2 If the affected Party, as defined in Paragraph 12.1 above, requests or
          experiences, on a cumulative basis, excusable delay(s) greater than
          ********** days, the Parties shall enter into good faith negotiations
          to develop a mutual course of action and/or an equitable adjustment to
          the affected terms of this Agreement.

     12.3 Notwithstanding the foregoing, if the Launch Date defined in Paragraph
          7.1 herein is delayed due to a Force Majeure event affecting either
          Party or a subcontractor thereof at any point in time after the
          shipment of the Spacecraft to the Launch Site has occurred, HCG shall
          reimburse Contractor for all reasonable expenses incurred as a result,
          including without limitation expenses for: support personnel standby;
          extra travel expenses; transport termination or rescheduling fees; and
          installation/de-installation of communication links to the Launch

ARTICLE 14.    TITLE AND RISK OF LOSS

     14.1 Title and risk of loss or damage in respect of all items to be
          delivered under this Contract shall pass from Contractor to HCG as
          follows:

          14.1.1 Risk of loss of the Spacecraft and title shall pass from
                 Contractor to HCG upon the earliest of: (i) the completion of
                 In-orbit Testing in accordance with Exhibit A, (ii) fifty (50)
                 days after Intentional Ignition (as defined in Article 15,
                 Paragraph 15.2 of this contract) or (iii) immediately before a
                 Partial Failure, Total Failure or Total Constructive Failure
                 (as each such term is defined in the applicable Hughes
                 Communications Galaxy Launch Insurance Contract or successor
                 contract) which occurs at or after Intentional Ignition.

          14.1.2 In respect to a Spacecraft which HCG directs Contractor to
                 store, title and risk of loss shall remain with the Contractor
                 until Final Acceptance as specified in Article 9.4 herein.

          14.1.3 Notwithstanding Paragraph 14.1.2 above, upon removal of the
                 Spacecraft from storage, the Contractor shall not assume risk
                 of loss relative to a Battery which HCG directs Contractor to
                 replace after the five-year storage period which disqualifies
                 the battery for a 12-year mission. In that event, Article 29
                 herein entitled "Effects of Storage on Batteries," shall apply.

          14.1.4 "Risk of Loss" for purposes of this Article 14 is limited to
                 the responsibility and liability for a Partial Failure, Total
                 Failure or Total Constructive Failure (as each such term is as
                 defined in the applicable Hughes Communications Galaxy Launch
                 Insurance Contract or successor contract). Responsibility and
                 liability for the Spacecraft prior to intentional ignition is
                 with the Contractor.

                       as specified in Article 9.4.

                 (iii) Such insurance shall be sufficient to cover the full
                       replacement value or selling price of the Spacecraft and
                       may be issued with deductibles, for which losses shall be
                       borne by the Contractor.

ARTICLE 15.  SPACECRAFT WARRANTY

     15.1 Contractor warrants that the Spacecraft, upon successful completion of
          Spacecraft in plant Tests pursuant to Article 9 herein, shall be free
          from any defects in material or workmanship and shall conform to the
          applicable specifications and drawings, as evidenced by the acceptance
          criteria in Exhibits A-D herein.

     15.2 This warranty shall start from the date of Preliminary Acceptance of a
          Spacecraft as stated in Article 9 herein, entitled "Inspection and
          Acceptance," and continue for a period of ************************ or
          until the Intentional Ignition (defined herein as the "Intentional
          Ignition of any rocket motor on the first stage of the launch
          vehicle") of the applicable launch vehicle, whichever is earlier. ***

          *********************************************************************
          *********************************************************************
          ******************* ("Warranty Time Period"). Contractor shall not be 
          liable in Contract or in Tort for any incidental, special, contingent,
          or consequential damages.

          Contractor, at its expense, correct or replace (at Contractor's
          option) such goods with conforming goods. If any time during the
          Warranty Time Period Contractor fails to correct or replace such
          defective goods and fails to initiate reasonable efforts to correct or
          replace such defective goods within a reasonable period after written
          notification and authorization from HCG, HCG may then, by contract or
          otherwise, correct or replace such defective goods and equitably
          adjust the price.

     15.4 Except as otherwise expressly agreed upon in this Contract, Contractor
          shall have no liability, or responsibility in Contract or in Tort with
          respect to a Spacecraft after Intentional Ignition (as defined in

ARTICLE 16.    INDEMNIFICATION

     16.1 Each Party shall indemnify and hold the other and/or all its officers,
          agents, servants, subsidiaries, affiliates, parent companies and
          employees, or any of them, harmless from any liability or expense in

          including but not limited to employees of the Parties, and their
          subcontractors, and of all other persons performing any part of the
          work hereunder, arising from any occurrence caused by an negligent act
          or omission of the indemnifying Party or its subcontractors, or any of
          them in connection with the work to be performed by such Party under
          this Contract. The indemnifying Party shall have the right, but not
          the obligation, to participate in any legal or other proceedings
          concerning claims for which it is indemnifying under this Article 16
          and to direct the defense of such claims. However, with respect to
          such legal or other proceedings, the indemnifying Party shall pay all
          expenses (including attorneys fees incurred by the indemnified Party
          in connection with such legal or other proceedings) and satisfy all
          judgments, costs or other awards which may be incurred by or rendered
          against the indemnified Party. The indemnifying Party shall not settle
          any such claim, legal or other proceeding without first giving thirty
          (30) days prior written notice of the Terms and Conditions of such
          settlement and obtaining the consent of the indemnified Party, which
          consent shall not be unreasonably withheld or delayed.

     16.2 Notwithstanding the foregoing, neither the Contractor nor its
          subcontractors shall have any liability in Contract or in Tort, for
          damages to or caused by the Spacecraft after Intentional Ignition (as
          defined in Paragraph 15.2), and Buyer shall obtain waivers of
          subrogation rights from Buyer's insurers against Contractor, and
          affiliates and subcontractors of Contractor.

ARTICLE 18.    PATENT/COPYRIGHT INDEMNITY

     18.1 Contractor shall indemnify and hold HCG harmless against any liability
          or expense as a result of claims, actions, or proceedings against HCG
          alleging the infringement of any trademarks, United States Copyright
          or mask work, United States Letters Patent, any other intellectual
          property rights, by any article fabricated by Contractor and delivered
          to HCG pursuant to this Contract as set forth below.

     18.2 Contractor agrees to defend at its own expense any claim, action,
          proceeding or request for royalty payments or any claim for equitable
          relief or damages against HCG, its officers, employees, agents, or
          subsidiaries based on an allegation that the manufacture of any item
          under this Contract or the use, lease, or sale thereof infringes any
          United States Letters Patent trademark, United States Copyright or
          mask work or any other intellectual property right, and to pay any
          royalties and other costs related to the settlement of such claim,
          action, proceeding or request and to pay the costs and damages,
          including reasonable attorney's fees finally awarded as the result of
          any claim, action or proceeding based on such request, provided that
          Contractor is given prompt written notice of such request or claim by
          HCG and given authority and such assistance and information as is
          available to HCG for resisting such request or for the defense of such
          claim, action or proceeding. Any such assistance or information which
          is furnished by HCG at the written request of Contractor is to be at
          Contractor's expense.

     18.3 In the event that, as a result of any such claim, action, proceeding
          or request: a) prior to delivery, the manufacture of any item is
          enjoined; or b) after delivery, the use, lease or sale thereof is
          enjoined, Contractor agrees to utilize its best effort to either: (1)
          negotiate a license or other agreement with plaintiff so that such
          item is no longer infringing; or (2) modify such item suitably or
          substitute a suitable item therefore, which modified or substituted
          item is not subject to such injunction, and to extend the provisions
          of this Article thereto. In the event that neither of the foregoing
          alternatives is suitably accomplished by Contractor, Contractor shall

ARTICLE 19.    RIGHTS IN INVENTIONS

     19.1 As used in this Contract, "Program Invention" shall mean any
          invention, discovery or improvement conceived of and first reduced to
          practice in the performance of Work under this Contract. Information
          relating to Inventions shall be treated as proprietary information in
          accordance with the provisions of this Contract. Rights to inventions
          conceived solely by Contractor or its employees shall vest completely
          with Contractor.

     19.2 Contractor shall be the owner of all Program Inventions invented
          solely by Contractor. Contractor grants Buyer a royalty-free,
          nonexclusive license in Program Inventions to use Program Inventions
          solely for the purposes of maintenance and operation of the Satellite
          and delivered Equipment. Contractor agrees that it will not revoke
          such license if Buyer is in compliance with the terms of the license.

          19.3.1 In the case of joint Inventions, that is, inventions conceived
                 jointly by one or more employees of both Parties hereto, each
                 Party shall have an equal, undivided one-half interest in and
                 to such joint Inventions, as well as in and to patent
                 applications and patents thereon in all countries.


          19.3.2 In the case of such joint Inventions, Contractor shall have the
                 first right of election to file patent applications in any
                 country, and Buyer shall have a second right of election. Each
                 Party in turn shall make its election at the earliest
                 practicable time, and shall notify the other Party of its
                 decision.

          19.3.3 The expenses for preparing, filing and securing each joint
                 Invention patent application, and for issuance of the
                 respective patent shall be borne by the Party which prepares
                 and files the application. The other Party shall furnish the
                 filing Party with all documents or other assistance that may be
                 necessary for the filing and prosecution of each application.

                 maintenance fees or other charges on a pending application or
                 on an issued patent, the Party which files the application
                 shall, prior to filing, request the other Party to indicate
                 whether it will agree to pay one-half of such taxes, annuities,
                 maintenance fees or other charges. If within sixty (60) days of
                 receiving such request, the non-filing Party fails to assume in
                 writing the obligation to pay its proportionate share of such
                 taxes, annuities, maintenance fees or other charges, or if

                 within sixty (60) days of demand, it shall forthwith relinquish

                 said application and patent.

     19.4 Each owner of a jointly-owned patent application or patent resulting
          therefrom shall, provided that it shall have fulfilled its obligation,
          if any, to pay its share of taxes, annuities, maintenance fees and
          other charges on such pending application or patent, have the right to
          grant non-exclusive licenses thereunder and to retain any
          consideration that it may receive therefor without obligation to
          account therefor to the other Party. In connection therewith, each of
          the Parties hereby consents to the granting of such non-exclusive
          licenses by the other Party and also agrees not to assert any claim
          with respect to the licensed application or patent against any
          licensee of the other Party thereunder during the term of any such
          license.

     19.5 No sale or lease hereunder shall convey any license by implication,
          estoppel or otherwise, under any proprietary or patent rights of
          Contractor, to practice any process with such product or part, or, for
          the combination of such product or part with any other product or

ARTICLE 28.    CHANGES

     28.1 Any changes requested by Contractor during the performance of this
          Contract, within the general scope of this Contract, which will add or
          delete Work, affect the design of the Satellite, change the method of
          shipment or packing, or the place or time of delivery, or will affect
          any other requirement of this Contract, shall be submitted in writing
          ("Change Proposal") to Buyer sixty (60) days prior to the proposed
          effective date of the change. If such Contractor requested change
          causes an increase or decrease in the total price or other terms of
          this Contract, Contractor shall submit a proposal to Buyer detailing
          the impact of such change.

     28.2 Buyer shall notify Contractor in writing within thirty (30) days after
          receipt of the requested change and price adjustment, if any, whether
          or not it agrees with and accepts such Change Proposal. If Buyer
          agrees with and accepts the Contractor requested Change Proposal,
          Contractor shall proceed with the performance of the Contract as
          changed and an amendment to the Contract reflecting the Change
          Proposal shall be incorporated into the Contract. If Buyer does not
          agree with the Contractor requested Change Proposal, the Parties shall
          attempt to reach agreement on such Change Proposal. If the Parties are
          unable to agree on the requested change and price adjustment, then the
          Parties shall proceed with the performance of this Agreement, as
          unchanged. In the event the Parties are able to reach agreement on the
          change, but not on the price adjustment component, then the Parties
          shall elevate such dispute to the Senior Executives of the respective
          companies for resolution. If resolution can not be achieved within a
          reasonable period of time under the circumstances, Buyer may make a
          qualified acceptance of the Change Proposal, accepting all matters
          other than price, and issue of price shall be submitted for resolution
          by arbitration in accordance with the provisions of Paragraph 32.2
          hereof. Pending such resolution of the price issue, the Parties shall
          perform their obligations under the Contract as if the Change Proposal
          had been accepted; provided, however, that Buyer shall pay any
          disputed amount of the price adjustment into an escrow account in
          accordance with Paragraph 28.4 hereof on the date such amount would
          have been due and payable had the Change

          Proposal been accepted, or if the Change Proposal could result in a
          downward adjustment in the Contract Price in excess of the amount
          remaining to be paid by the Buyer, Contractor shall deposit the
          disputed amount of such excess into an escrow account in accordance
          with Paragraph 28.4 hereof. The final change price adjustment achieved
          either by the Parties, or through an arbitration award shall be paid
          in accordance with the payment plan agreed by the Parties or, if
          applicable, by the Arbitrator.

     28.3 Buyer may submit to Contractor in writing (a "Change Order Request")
          detailing any changes requested by Buyer during the performance of
          this Contract, within the general scope of the Contract, which will
          add or delete Work, affect the design of the Satellite, change the
          method of shipment or packing, or the place or time of delivery, or
          will affect any other requirement of this Contract. Contractor shall
          respond to such Change Order Request in writing to Buyer within thirty
          (30) days after such request. If Contractor determines that the change
          requested by Buyer is feasible and can be made at an additional cost
          and with no associated delays, then Contractor shall so notify, Buyer
          and Contractor shall commence implementing such change. If the
          Contractor determines otherwise, then, Contractor shall submit to
          Buyer, a proposal detailing the impact of such change and the price
          adjustment, if any, (the "Change Order Offer"). Buyer shall notify
          Contractor in writing, within thirty (30) days after receipt of
          Contractor's Change Order Offer, whether or not it agrees with and
          accepts Contractor's Change Order Offer. If Buyer agrees with and
          accepts Contractor's Change Order Offer, Contractor shall immediately
          proceed with the performance of the Contract as changed and an
          amendment to the Contract reflecting such change shall be incorporated
          into the Contract. If Buyer does not agree with the Contractor's
          Change Order Offer, the Parties shall attempt to reach agreement on
          such Change Order Offer. In the event the Parties are able to reach
          agreement on the change, but not on the price adjustment component,
          then the Parties shall elevate such dispute to the Senior Executives
          of the respective companies for resolution. If resolution can not be
          achieved within a reasonable period of time under the circumstances,
          Buyer may make a qualified acceptance of the Change Order Offer,
          accepting all matters other than price, and the issue of price shall

          provisions of Paragraph 32.2 hereof. Pending such resolution of the
          price issue, the Parties shall perform their obligations under the
          Contract as if the Change Order Offer had been accepted; provided
          however, that the Buyer shall pay any disputed amount of the price
          adjustment into an escrow account in accordance with Paragraph 28.4
          hereof on the date such amount would have been due and payable had the
          Change Order Offer been accepted, or if the Change Order Request could
          result in a downward adjustment in the Contract Price in excess of the
          amount remaining to be paid by Buyer, Contractor shall deposit the
          disputed amount of such excess into an escrow account in accordance
          with Paragraph 28.4 hereof. The dispute shall then be resolved by
          arbitration under the provisions of Article 32, entitled "Disputes."
          The final change price adjustment achieved either by the Parties, or
          through an arbitration award shall be paid in accordance with the
          payment plan agreed by the Parties or, if applicable, by the
          Arbitrator.

     28.4 Escrow Provisions - Disputed Amounts

          Disputed amounts with respect to any change under this Article 28
          shall be paid into an interest bearing escrow account to be
          established at Bank of America, Concord, California. Upon settlement
          of the dispute as to such payment and alleged breach in accordance
          with Article 32, the Party entitled to the amount or part thereof in
          escrow, shall receive such amount together with all accrued interest
          thereon and the other Party shall pay all costs and fees associated
          with the escrow of said amount. The placement of disputed amounts into
          an escrow account shall not relieve either Party of its remaining
          obligations under this contract.

ARTICLE 29.  EFFECTS OF STORAGE ON BATTERIES

     For Spacecraft batteries to provide the required minimum twelve (12) years
     of in-orbit services per Exhibit B, Galaxy X Spacecraft Specification, it
     is understood that launch must occur within five (5) years from the date of
     activation of the first battery cell. In the event Buyer directs Contractor
     to store any deliverable Spacecraft and the period of such storage causes a
     launch later than five (5) years from the date of activation of that
     Spacecraft's first battery cell and HCG directs Contractor to install
     replacement batteries to meet twelve (12) years in-orbit service
     requirement, then HCG shall pay Contractor its costs plus a **** profit
     rate.

ARTICLE 30.    INTER-PARTY WAIVER OF LIABILITY

     30.1 Prior to the time HCG and the Contractor enter the premises at the
          Launch Site, they each agree that they will not make a claim against
          each other for an event that occurs at the Launch Site premises
          involving damage to, loss of, or loss of use of their property or the
          property of others in their possession, caused by the fault or
          negligence of the other Party to this Contract, or otherwise caused by
          any defect in any product manufactured or sold by the other Party to
          this Contract. Such claims are waived and each Party will bear its own
          losses. HCG will include a comparable clause in each of its contracts
          with vendors, subcontractors or customers for services or benefits
          expected as a result of the launch or orbiting of this Galaxy
          Satellite. Such comparable clause shall include a requirement to flow
          the clause down to lower-tier contractors.

     30.2 Notwithstanding any other provisions of this Contract, prior to the
          time any Party, associated with the Galaxy X launch activities at the
          Launch Site, shall enter the premises at the Launch Site, such Parties
          shall be required to sign an Inter-Party Waiver of Liability
          consistent with that between HCG and the Contractor as incorporated
          herein under Paragraph 30.1 of this provision or other similar
          agreement as may be required by the launch agency. Each Party shall
          have the responsibility to assure that all the Parties associated with
          the launch of Galaxy X Spacecraft (for which they have control or
          privity of Contract with hereunder) have executed said Inter-Party
          Waiver of Liability.

          with the provisions of Exhibit B Galaxy X Spacecraft Specification,
          the deliverable Spacecraft (including separate storage of Batteries,
          if needed) for a period of up to two (2) years from the date of their
          delivery to Buyer. HCG shall provide written notice to the Contractor
          not later than six (6) months prior to the scheduled delivery of said
          Spacecraft. Contractor's price for providing storage shall be provided
          to Buyer in accordance with Article 29, "Changes," (and such price
          shall be deemed a "Change Proposal" for purposes of Article 29) within
          30 days after receipt of Buyer's notice to store such Spacecraft and
          Contractor shall provide storage facilities. If such storage
          facilities are unavailable, Contractor and Buyer shall hold
          discussions to determine a mutually agreed storage arrangement.

     31.2 Six (6) months prior to a stored Spacecraft's scheduled launch date,
          Buyer shall, by notice in writing, order the Contractor to remove said
          Spacecraft from storage and ship it to a Launch Site designated by
          Buyer. The cost for storage and additional transportation costs
          exceeding that required to transport the Spacecraft to the FOB point
          specified herein, shall be borne by Buyer. These will be in addition
          to any charges which become the obligation of the Buyer per Article 17
          herein entitled "Spacecraft Not Launched Within Six Months After
          Acceptance."

    33.1  Neither Party shall assign, or transfer this Contract or any of its
          rights, duties or obligations thereunder to any person or entity, in
          whole or part without the prior written consent of the other Party
          except that either Party may assign or transfer any of its rights,
          duties or obligations under this Contract, either in whole or in part,
          to its parent company, subsidiary or affiliate/1/ in which the
          assigning Party has a controlling interest thereof. In addition,
          notwithstanding anything in this Article 33 to the contrary, the
          consent of Contractor shall not be required for, and Paragraph 33.2
          shall not apply to, any assignment of this Contract from HCG to
          Magellan International, Inc. (which currently contemplates changing
          its name to PanAmSat Corporation), or an affiliate thereof, in
          connection with the consummation of the transactions contemplated by

              fulfill the obligations of this Contract; and

          (2) any such assignment or transfer shall not jeopardize any data
              rights or competitive position, or violate laws related to export
              or technology transfer, or otherwise increase the other Party's
              risks or obligations.

          If the requesting Party cannot so demonstrate, both Parties agree to
          negotiate in good faith suitable modifications and new provisions to
          this Contract which would mitigate the above risks and/or bring this
          Contract into conformance with applicable laws.
