                                    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

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").

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
<PAGE>
costs, expenses and Liabilities allocated to Univisa under this Agreement) prior

                  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

                  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:

                       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
<PAGE>
                           (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
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

Article 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

unless another date, time or place is agreed to in writing by the parties hereto
(the "Closing").

                  2.2 Documents to be Delivered. To effect the Univisa

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 so
to qualify or be in good standing would not have a material adverse economic
impact on the assets or business of such member of the Contributing Group,
Univisa and the Subsidiaries of Univisa, taken as a whole, or impair the right
or ability of the parties hereto to consummate the transactions contemplated
hereby. Each member of the Contributing Group, Univisa and each Subsidiary of
Univisa has heretofore made available true, complete and correct copies of its
Certificate of Incorporation and Bylaws (or other organizational documents, as
appropriate) as currently in effect together with all amendments thereto. No
resolution has been adopted to amend any of such Certificates of Incorporation
or Bylaws (or other organizational documents, as appropriate) except as
expressly called for by this Agreement. No member of the Contributing Group,
Univisa nor any Subsidiary of Univisa (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 each such entity's knowledge, no action or request is pending
to declare it bankrupt. Contributor has made available to Newco minute books for
each of Univisa and its Subsidiaries 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) of each
such entity since its date of formation.

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 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
<PAGE>
would have a material adverse economic impact on the assets or business of such
member, or a member of the Contributing Group, or would 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
<PAGE>
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 Subsidiaries and affiliates, to the extent legally permissible, to,
(i) 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 ction 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
<PAGE>
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 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, (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
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:
<PAGE>
               (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
party, threatened against, relating to or involving or otherwise affecting 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-occurrence of which would cause any representation or warranty of such
party contained in this Agreement to be untrue or inaccurate in any 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.
<PAGE>
                  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 (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
<PAGE>
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 efforts to find another qualified entity that is reasonably
acceptable to each other and that is willing to serve as the Trustee.

                                   ARTICLE VI
                                   CONDITIONS

                  6.1 Conditions to Each Party's Obligation to Effect the
Univisa Contribution. The respective obligations of each party to effect the
Univisa Contribution shall be subject to the satisfaction on or prior to the
Closing Date (or, if permissible, waiver by each party for whose benefit such
conditions exist) of the following conditions:

                           (a) No Order. No Governmental 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; 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 PanAmSat shall have been amended so that the consummation of
the transactions contemplated by this Agreement shall not cause the shares of
Class B Common Stock outstanding as of the date hereof to be converted or

and the Newco Group agree that so long as any books, records and files relating
to the business, properties, assets or operations of Univisa and USHI, to the
extent that they pertain to the Univisa Stock prior to the Closing Date, remain

                  7.2 Further Assurances. On and after the Closing Date, each

       merge, consolidate or combine Univisa or USHI with or into Newco,
       PanAmSat or any other entity;

                              (ii) recapitalize in any way the classes of Class
       A Common Stock, Class B Common Stock and Common Stock of PanAmSat as they

                  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
<PAGE>
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 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
<PAGE>
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.

                           (a) By Parent and Contributor.

                              (i) Parent and Contributor, jointly and severally,

       representatives, successors and assigns, from and against any and all
       costs, losses (including diminution in value), taxes, Liabilities,
       obligations, damages, lawsuits, deficiencies, claims, demands, and
       expenses (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
<PAGE>
       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,
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
<PAGE>
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
<PAGE>
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 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.
<PAGE>
                  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 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
<PAGE>
         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.

                  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) 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.
<PAGE>
                  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
<PAGE>
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 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.
<PAGE>
                  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

                  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

                  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
<PAGE>
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.

part of the Trust Estate, subject to the provisions of this Agreement.

                           (d) For purposes of this Agreement, as of any date of
valuation, and unless otherwise expressly provided herein, Newco Common Stock
shall be valued at Fair Market Value and cash or Cash Equivalents shall be

including zero, as the Trustee may in good faith determine.

              5.        Required Trust Estate Values.

                           (a) The Trust Estate shall be valued by the Trustee
at the end of each calendar quarter (a "quarterly valuation").

                           (b) (i) After the date hereof and prior to the date
which is 16 months after the date hereof, at any quarterly valuation the value
of Fund B shall be no less than $ 175 million, of which no less than $ 25
million shall be cash or Cash Equivalents.

                              (ii) After the date which is 16 months after the
date hereof and prior to the termination of this Agreement, at any such
quarterly valuation, the value of Fund B shall be no less than $ 100 million, of
which no less than $ 25 million shall be cash or Cash Equivalents.
<PAGE>
                              (iii) After the Expiration Date, the value of Fund
B may be reduced to the Maintenance Level, all of which may be maintained in
Newco Common Stock.

Notwithstanding the foregoing, while there is any Tax Claim, Final Tax Amount or
pending Liabilities Claim, Fund B shall be maintained in an amount equal to the
sum of all Tax Reserves for all Tax Claims, Final Tax Amounts, the Maintenance
Level, all Pending Amounts, and all other amounts required to be paid out from
or maintained in Fund B.

                           (c) At any quarterly valuation, the value of Fund A
shall be no less than the then amount of Scheduled Liabilities.

                           (d) If the values of Funds A and B as determined by
the Trustee in any quarterly evaluation are less than the values then required
to be maintained under Sections 5(b) and 5(c) hereof (a "deficiency"), the
Trustee shall notify the parties and, within 15 days, Contributor and Parent
shall cause to be deposited with the Trustee, as part of the Trust Estate, cash
or Cash Equivalents in the amount of the deficiency in Fund A and cash or Cash
Equivalents or Newco Common Stock in the amount of the deficiency in Fund B,
provided that no less than $ 25 million of Fund B shall at all times consist of
cash or Cash Equivalents (such deposits, a "Make-Whole Payment").
Notwithstanding the foregoing, if the deficiency in Fund B would be eliminated
if the value of the Newco Common Stock increased 11.1 % or less, the deficiency
in Fund B need not be deposited.

                           (e) If the values of Funds A and B as determined by
the Trustee in any quarterly evaluation are more than the values then required
to be maintained under Sections 5(b) and (c) hereof (a "surplus"), the Trustee
shall notify the parties and, within 15 days, shall cause the surplus of cash or
Cash Equivalents in Fund A to be released to Contributor, and shall cause the
surplus of cash or Cash Equivalents or Newco Common Stock in Fund B to be
released to Contributor, provided that no less than $ 25 million of Fund B shall
at all times consist of cash and Cash Equivalents. Notwithstanding the
foregoing, if the surplus in Fund B would be eliminated if the value of the
Newco Common Stock decreased by 10% or less, the surplus in Fund B shall not be
released. Further, no amount shall be released to Contributor pursuant to this
Section 5(e) while an Event of Default is continuing hereunder.

                           (f) Contributor and Parent may deliver a Make-Whole
Payment consisting of cash, Cash Equivalents or (to the extent permitted under
Section 5(d) hereof) Newco Common Stock owned by Contributor or Parent or by any
Subsidiary of Parent, if, in the case of Newco Common Stock owned by any such
Subsidiary, (i) such Subsidiary executes and delivers to the Trustee an
agreement reasonably satisfactory to the Trustee and Newco Group by which such
Subsidiary agrees to join in and be bound by this Agreement and the Pledge and
Security Agreement on the same terms and conditions as those by which Parent is
bound, together with such financing statements, assignments and transfer
instruments requested as to such Subsidiary by the Trustee or Newco Group, and
(ii) Parent executes and delivers to the Trustee an instrument warranting the
due authorization, execution, delivery, legality and enforceability of such
<PAGE>
agreement, financing statements, assignments and transfer instruments and
guaranteeing due and punctual payment and performance of all liabilities and
obligations of such Subsidiary thereunder.

      6.        Trust Estate Scheduled Liabilities - Determination and Payment.

                           (a) The Trustee shall maintain on an ongoing basis a
schedule of Known Liabilities (the "Schedule of Liabilities"). The initial
Schedule of Liabilities is the Statement of Liabilities. Each Scheduled
Liability shall be stated at an amount equal to its liquidated amount if it is a
Known Liability which is liquidated (i.e., in an amount certain) or at its
related reasonable reserve if it is a Known Liability which is unliquidated
(i.e., in an amount which is uncertain or contingent). The liquidated amount or
the reserve, as the case may be, with respect to any Known Liability is its
"Scheduled Amount." Amounts claimed under Tax Claims and Final Tax Amounts shall
not be Scheduled Liabilities.

                           (b) The Schedule of Liabilities shall also include
for Known Liabilities which are liquidated their respective discrete (one or
more) or periodic due dates and the names and addresses of the persons entitled
to payment. Unless the Representative or Indemnitees' Agent shall give notice to
the Trustee at least 10 days prior to the due date of any Known Liability which
is liquidated that payment should not be made on such due date, the Trustee
shall pay from Fund A Known Liabilities which are liquidated when due, and the
related Known Liability shall be deemed satisfied and removed (to the extent
satisfied) from the Schedule of Liabilities.

                           (c) If Known Liabilities which are liquidated arise
after the date hereof, the party who becomes aware of such Known Liabilities
shall give notice, and provide relevant documentation, if any, to the other
parties. If the Representative did not give such notice and does not object to
such notice within 10 days of the notice, the subject Known Liabilities shall be
added to the Schedule of Liabilities.

                           (d) If Known Liabilities which are unliquidated arise
after the date hereof, the party who becomes aware of such Known Liabilities
shall give notice, and provide relevant documentation, if any, to the other
parties and shall propose a reasonable reserve therefor. If no party objects to
such notice within 10 days of the notice, the subject Known Liabilities shall be
added to the Schedule of Liabilities at the amount of the proposed reserve.

                           (e) If there shall occur any developments or events
which cause any party to reasonably believe that the reserve for a Known
Liability which is unliquidated or the scheduled amount of a Known Liability
which is liquidated should be adjusted, the party shall give notice to the other
parties of the proposed adjustment and the basis therefor. If no party objects
to such notice within 10 days of the notice, the reserve or Scheduled Amount for
such Known Liability shall be adjusted as proposed.

                           (f) If Known Liabilities which are unliquidated
become liquidated through final resolution or settlement, the party responsible
for the resolution shall give notice to the other parties of the nature and
amount of the resolution and present evidence thereof in the form of a release,
<PAGE>
receipt, or otherwise. If no party objects to such notice within 10 days of the
notice, the subject Known Liability shall be deemed liquidated at the amount of
the resolution and, up to the Scheduled Amount, shall be paid as provided in
Subsection (b) above.

                           (g) In addition, if the Representative shall give
notice to the other parties hereto at least 15 days prior to a quarterly
valuation that Parent or Contributor has satisfied, or caused to be satisfied,
any Known Liability and shall present evidence thereof in the form of a receipt,
release or other proof of its claim, then if the Indemnitees' Agent does not
give notice of objection within 10 days of the Representative's notice, the
Trustee shall reimburse Contributor or Parent (as the case may be) for the
amount paid in satisfaction of the Known Liability up to its Scheduled Amount.
Such Known Liability shall thereafter be deemed satisfied and removed (to the
extent satisfied) from the Schedule of Liabilities.

                           (h) In addition, if the Indemnitees' Agent shall give
notice to the other parties hereto at least 15 days prior to a quarterly
valuation that HCI or Newco has incurred or has satisfied, or caused to be
satisfied, any Known Liability and shall present evidence thereof in the form of
a receipt, release or other proof of its claim, then if the Representative does
not give notice of objection within 10 days of the Indemnitees' Agent's notice,
the Trustee shall reimburse HCI or Newco (as the case may be) for the amount
paid in satisfaction of the Known Liability up to its Scheduled Amount. Such
Known Liability shall thereafter be deemed satisfied and removed (to the extent
satisfied) from the Schedule of Liabilities.

                           (i) When so directed in writing by a Representative
upon at least 10 days' prior written notice, if (and only if) no Make-Whole
Breach is then continuing under Section 8(c) hereof, Indemnitees' Agent shall
direct the Trustee (i) to sell or otherwise liquidate (in any commercially
reasonable manner set forth in the Representative's notice) Cash Equivalents or
Newco Common Stock held by the Trustee in Fund B as necessary to pay and
discharge a Tax Claim or Final Tax Amount and (ii) to pay directly to the taxing
authority certified in the Representative's notice to be entitled to payment of
such Tax Claim or Final Tax Amount, on account and in satisfaction of such Tax
Claim or Final Tax Amount, such amount as is set forth in the Representative's
notice.

                  7. Certain Disputes. In the event that either a Representative
or Indemnitees' Agent shall give notice of objection to any notice given under
any of the provisions of Section 6, the parties (other than the Trustee) shall
promptly meet and confer and attempt to resolve the objection. If they succeed,
they shall promptly and jointly notify the Trustee and the Trustee shall act in
accordance with the notice. If they shall not succeed within 15 days of the
notice of objection, they shall, within an additional 45 days, commence and
complete an arbitration proceeding in accordance with the provisions of Section
24 hereof. Unless the parties shall otherwise jointly instruct the Trustee, the
Trustee shall act with respect to the subject Known Liability in accordance with
the arbitrator's award when received. A party must have a reasonable basis in
giving any such notice of objection and shall set forth the basis of its
objection in the notice.
<PAGE>
  8.      Certain Releases and Substitutions; Consequences of Make-Whole Breach.

                           (a) When so directed in writing by a Representative
upon at least 10 days' prior written notice, Indemnitees' Agent shall instruct
the Trustee to release from Fund B and deliver to Contributor any or all cash,
Cash Equivalents and Newco Common Stock then held by the Trustee in Fund B, but
only if prior to any such release and delivery there is deposited with the
Trustee, to be held as part of the Trust Estate and as part of Fund B, an
irrevocable standby letter of credit which shall be issued in favor of the
Trustee in an amount at least equal to the value of the cash, Cash Equivalents
and Newco Common Stock so to be released and which shall be in form and
substance and issued by a bank satisfactory to Newco in its reasonable
discretion (a "Letter of Credit"). Each Letter of Credit in any event (i) must
be available for payment to the Trustee under each, any and all of the
circumstances under which any payment by the Trustee is or becomes due from the
Trust Estate pursuant to the provisions of this Agreement and, in addition, (ii)
must be freely available for payment to the Trustee in the full amount of such
Letter of Credit at all times during the period that commences on the 30th day
prior to the date on which such Letter of Credit, by its terms, expires, unless
a substitute Letter of Credit has been delivered to and approved and accepted by
the Trustee. Unless otherwise instructed by Indemnitees' Agent, the Trustee
shall draw or demand payment under each Letter of Credit, for the full amount of
such Letter of Credit, at least 20 days prior to its expiration. The Trustee
shall also draw or demand payment under Letters of Credit at any time when the
assets in Fund B may be applied to fund payment of a Known Liability or a Tax
Claim or Final Tax Amount or any other amount payable from Fund B. For purposes
of valuation of Fund B, the amount that is available to be drawn, but has not
been drawn, under any Letter of Credit held in Fund B shall be counted as Cash
Equivalents.

                           (b) When so directed in writing by a Representative
upon at least five days prior written notice, Indemnitees' Agent shall instruct
the Trustee to release from Fund B and deliver to Contributor the number of
shares of Newco Common Stock specified in such notice, but only if Contributor
transfers to the Trustee, to be held as part of the Trust Estate, cash in an
amount equal to the Fair Market Value of such shares of Newco Common Stock,
concurrently with and in exchange for delivery of such shares of Newco Common
Stock.

                           (c) If Contributor and Parent at any time fail to
deposit any Make-Whole Payment required to be deposited by them pursuant to
Section 5(d) hereof (a "Make-Whole Breach"), then at all times thereafter until
the full amount of such Make-Whole Payment is received by the Trustee, in cash
and as part of the Trust Estate, (i) Indemnitees' Agent shall have the sole
power to direct and control the application of the Trust Estate to the
settlement, payment and satisfaction of any and all Scheduled Liabilities,
Liabilities Claims, Final Tax Amounts and Tax Claims (whether or not disputed or
liquidated), at such times and in such amounts, manner and order and on such
conditions as Indemnitees' Agent from time to time, in its sole discretion, may
determine and (ii) the Trustee shall honor all instructions received by it in
writing from Indemnitees' Agent to collect any or all Cash Equivalents, sell any
or all Newco Common Stock and otherwise liquidate any and all property of the
Trust Estate and pay, from cash in the Trust Estate, any or all such Scheduled
Liabilities, Liabilities Claims, Final Tax Amounts and Tax Claims, in such
amount, manner and order as Indemnitees' Agent in its sole discretion may elect
<PAGE>
and direct, in each case (x) whether or not any claim so paid has then been
settled or liquidated or is then binding upon Contributor or Parent under any
judgment or award, (y) whether or not Contributor or Parent has participated in
or approved any settlement or payment of any claim, and (z) whether or not
Parent or Contributor has given the Trustee notice of objection to any such
instructions or notice of any demand for arbitration or judicial relief in
respect thereof. No such action by Indemnitees' Agent shall be determinative of
any liability of Parent or Contributor for or as to any Liability or Damages
pursuant to the provisions of the Stock Contribution and Exchange Agreement.

             9.        Termination of Agreement.

                           (a) Ninety (90) days after the 10th anniversary of
the date hereof (the "Cut-off Date"), any property in the Trust Estate in excess
of the amount required to pay the sum of all Scheduled Liabilities, all Tax
Reserves for all Tax Claims and Final Tax Amounts, all Pending Amounts, and all
other amounts required to be paid from Fund B (the "Excess Amount") shall be
released to Contributor, unless at such time the statute of limitations
applicable to the assessment of United States federal income tax against Univisa
or USHI (or any affiliate or Subsidiary of either of them) with respect to any
Pre-Closing Period shall not have expired, in which event any Excess Amount
shall be determined and released to Contributor upon the day following the
earliest to occur of (i) the expiration of such statute of limitations, (ii) a
final determination by the Internal Revenue Service to the effect that neither
Univisa nor USHI (nor any affiliate or Subsidiary of either of them) has any
unsatisfied liability for taxes for which Parent and Contributor would be liable
pursuant to Section 8.2(a)(ii) of the Stock Contribution and Exchange Agreement,
and (iii) the assertion of a Tax Claim by the Internal Revenue Service.

                           (b) After the Cut-off Date, no Known Liabilities
shall be added to the Schedule of Liabilities other than as a result of the
determination of Pending Amounts.

                           (c) After satisfaction and discharge of all remaining
Scheduled Liabilities and Final Tax Amounts, determination of all Pending
Amounts and final, indefeasible and nonappealable satisfaction and discharge of
all Tax Claims and Liabilities Claims, all amounts remaining in the Trust Estate
shall be delivered to Contributor.

                           (d) Upon the final distribution of all of the Trust
Estate in accordance with the terms of this Agreement, this Agreement shall
terminate.

                  10. Directions to Trustee. Both prior to and after the
occurrence of any Event of Default, the Trustee shall exercise and enforce its
rights and remedies under the Pledge and Security Agreement in accordance with
such instructions as the Trustee from time to time may receive from Newco Group,
so long as such instructions do not, in the good faith opinion of the Trustee,
require it to engage in any action which would violate any law or expose it to
liability for which it has not received indemnification from Newco Group on
terms reasonably satisfactory to it.
<PAGE>
                  11. Tax Matters. Each party to this Agreement shall provide a
completed IRS Form W-8 or Form W-9 to the Trustee at the signing of this
Agreement. The Trustee may delay accepting Trust Estate until the IRS forms have
been provided. Subject to Section 14, Newco Group, Contributor and Parent,
jointly and severally, covenant and agree to indemnify and hold the Trustee
harmless against all liability for tax withholding and/or reporting for any
payments made by the Trustee pursuant to this Agreement.

                  12. Duties of the Trustee. The Trustee shall have no duties or
responsibilities other than those expressly set forth in this Agreement, and no
implied duties or obligations shall be read into this Agreement against the
Trustee. The Trustee shall have no duty to enforce any obligation of any person,
other than as provided herein. The Trustee shall be under no liability to anyone
by reason of any failure on the part of any party hereto or any maker, endorser
or other signatory of any document or any other person to perform such person's
obligations under any such document.

                  13. Liability of the Trustee; Withdrawal. The Trustee shall
not be liable for any action taken or omitted by it, or any action suffered by
it to be taken or omitted, in good faith, and in the exercise of its own best
judgment, and may rely conclusively and shall be protected in acting upon any
order, notice, demand, certificate, opinion or advice of counsel (including
counsel chosen by the Trustee), statement, instrument, report or other paper or
document (not only as to its due execution and the validity and effectiveness of
its provisions, but also as to the truth and acceptability of any information
therein contained) which is believed by the Trustee to be genuine and to be
signed or presented by the proper person(s). The Trustee shall not be held
liable for any error in judgment made in good faith by an officer of the Trustee
unless it shall be proved that the Trustee was grossly negligent in ascertaining
the pertinent facts or acted intentionally in bad faith. The Trustee shall not
be bound by any notice of demand, or any waiver, modification, termination or
rescission of this Agreement or any of the terms hereof, unless evidenced by a
writing delivered to the Trustee signed by the proper party or parties and, if
the duties or rights of the Trustee are affected, unless it shall give its prior
written consent thereto.

                  Without limitation, the Trustee shall not be responsible for
and may conclusively rely upon and shall be protected, indemnified and held
harmless by Contributor and Parent, acting jointly and severally, for the
sufficiency or accuracy of the form of, or the execution, validity, value or
genuineness of any document or property received, held or delivered by it
hereunder, or of the signature or endorsement thereon, or for any description
therein; nor shall the Trustee be responsible or liable in any respect on
account of the identity, authority or rights of the persons executing or
delivering or purporting to execute or deliver an document, property or this
Agreement.

                  In the event that the Trustee shall become involved in any
arbitration or litigation relating to the Trust Estate, the Trustee is
authorized to comply with any final, binding and nonappealable decision reached
through such arbitration or litigation.

                  The Trustee may resign at any time and be discharged from its
duties or obligations hereunder by giving notice to the other parties. Such
resignation shall take effect when a successor Trustee has been appointed by
<PAGE>
Newco and has accepted the trusts herein provided. If a successor Trustee does
not take office within 60 days after the retiring Trustee resigns, the retiring
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to Newco Group. Thereupon, the
resignation of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Agreement. The successor Trustee shall mail a notice of its succession to
Contributor and Parent. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee provided all sums owing
to the retiring Trustee have been paid.

                  14. The Trustee's Fee. All fees and reasonable expenses of the
Trustee for its services hereunder, shall be paid by Contributor and Parent.
Newco Group, Contributor and Parent, jointly and severally, hereby agree to
indemnify the Trustee for, and to hold it harmless against any loss, liability
or expense incurred without negligence or wilful misconduct on the part of the
Trustee, including without limitation legal or other fees arising out of or in
connection with its entering into this Agreement and carrying out its duties
hereunder, including without limitation the costs and expenses of defending
itself against any claim of liability in the premises or any action for
interpleader. The Trustee shall be under no obligation to institute or defend
any action, suit, or legal proceeding in connection herewith, unless first
indemnified and held harmless to its satisfaction in accordance with the
foregoing, except that the Trustee shall not be indemnified against any loss,
liability or expense arising out of its bad faith, gross negligence or willful
misconduct. Such indemnity shall survive the termination or discharge of this
Agreement or resignation of the Trustee. The Trustee shall be reimbursed by
Contributor and Parent for any reasonable expenses or disbursements incurred in
connection with the performance of the Trustee's obligations hereunder including
without limitation the actual cost of legal services should the Trustee deem it
necessary to retain an attorney.

                  15. Inspection. All funds or other property held as part of
the Trust Estate shall at all times be clearly identified as being held by the
Trustee hereunder. Any party hereto may at any time during the Trustee's
business hours (with reasonable notice) inspect any records or reports relating
to the Trust Estate.

                  16. 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

                  17. Non-Exclusive Remedy. Newco Group, Contributor and Parent
agree and acknowledge that the Trust Estate shall not be Newco Group's exclusive
method of receiving indemnification from Contributor and Parent pursuant to
Section 8.2 of the Stock Contribution and Exchange Agreement and Contributor and
Parent shall be and remain in all respects personally liable for all
Indemnification Obligations and each liability may be enforced by any lawful
means.
<PAGE>
                  18. Modification. 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.

                  19. 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 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.

                  20. Assignment. Except for assignments by a member of the
Newco Group to any affiliate or Subsidiary of such member with respect of some
or all of its rights under this Agreement (which assignment can be made without
the written consent of Contributor or Parent), 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 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.

                  21. 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).

                  22. Interest in Trust Estate. Neither Contributor nor Parent
has any interest in the Trust Estate except only as to any property which has
been released from the Trust Estate and delivered to Contributor or Parent as
herein provided, effective upon such release and delivery.

         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 unless such party did not in good faith seek
to resist or object to the imposition or entering of such order or judgment.
<PAGE>
                  24. 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 this 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.

                  25. 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.

                  26. Counterparts. This Agreement may be executed in two or
more counterparts, each of which will be considered one and the same instrument
and shall become effective when executed and delivered by each of the parties.

                  27. Specimen Signature. The Representative and Indemnitees'
Agent shall each present a specimen signature to the Trustee upon the execution
hereof.

                  IN WITNESS WHEREOF, the parties hereto have executed this
Collateral Trust Agreement as of the date first written above.

       assets are located or its material operations are conducted, except where
       the failure to be so qualified could not reasonably be expected to cause
       a change that would be material and adverse to such Debtor.

                           (i) Each Debtor has the corporate or partnership
       power to execute, deliver and perform its obligations under the

       document, and (iii) do not and will not result in or require the creation
       of any Lien (other than pursuant to the Collateral Trust Agreement and

       and no notice to or filing with, any governmental officer, department,
       agency or authority is required for the due execution, delivery and
       performance by each Debtor of the Collateral Trust Agreement, except the
       filing of financing statements to perfect Secured Party's security
       interest which have been duly filed.

                           (l) The Collateral Trust Agreement and this Agreement

                           (m) The execution, delivery and performance by each
       Debtor of the Collateral Trust Agreement and this Agreement (i) do and
       will comply with all applicable laws, (ii) do and will comply with, and
       do not and will not conflict with, constitute a breach of or give rise to
       any Lien, default, event of default or other adverse consequence under,
       any note, indenture, undertaking, agreement or other contractual
       obligation that is binding upon any Debtor or secured by or enforceable

         payments on account of the Secured Obligations required to be made
         therefrom, or in exchange or substitution therefor, and each Debtor

occurrence of any Event of Default, and from time to time on each occasion when
an Event of Default has occurred and is continuing, Secured Party may exercise
and enforce each and all of the rights and remedies available to a secured party
<PAGE>
upon default under the Code or other applicable law and each and all of the
following rights and remedies:

                           (a) Secured Party may notify any or all account

         reasonably convenient to it and the Debtors.

                           (c) Secured Party may cause any or all Newco Common
         Stock and other instruments or investment securities constituting part

         exchange or market or at Secured Party's offices or at any other
         location, for cash, on credit or for future delivery, and may enter
         into all contracts necessary or appropriate in connection therewith,
         without any notice whatsoever unless required by law, subject to the
         following limitations:

                           (1) Secured Party may sell or otherwise dispose of
                  Newco Common Stock held in the Trust Estate at any particular
                  time only if the cash and the immediately realizable net
                  liquidation value of Cash Equivalents and Letters of Credit
                  then held in the Trust Estate are not sufficient to pay in
                  full (i) all amounts which Secured Party is then required or
                  has then been instructed to pay out from the Trust Estate
                  pursuant to the Collateral Trust Agreement and (ii) all
                  Secured Obligations which are then payable; and

                           (2) Secured Party shall not sell or otherwise dispose
                  of shares of Newco Common Stock at any particular time in
                  excess of a number of shares (determined on a rounded-up
                  commercially reasonable regular lot basis) the proceeds of
                  which would be sufficient, when added to the cash and the
                  immediately realizable net liquidation value of Cash
                  Equivalents and Letters of Credit then held in the Trust
                  Estate, to pay in full (i) all amounts which Secured Party is
                  then required or has then been instructed to pay out from the
<PAGE>
                  Trust Estate pursuant to the Collateral Trust Agreement , (ii)
                  all amounts which Secured Party in good faith anticipates it
                  will be required or instructed to pay out from the Trust
                  Estate on account of Known Liabilities and pending Tax Claims
                  pursuant to the Collateral Trust Agreement within the next 90
                  calendar days (and for such purpose Secured Party may rely
                  conclusively on a certificate as to such amounts given to
                  Secured Party by Newco Group), and (iii) all Secured
                  Obligations which are then payable.

         The Debtors agree that at least 10 calendar days' written notice to the
         Debtors of the time and place of any public sale or the time after
         which any private sale is to be made shall be commercially reasonable.
         The giving of notice of any such sale or other disposition shall not
         obligate Secured Party to proceed with the sale or disposition, and any
         such sale or disposition may be postponed or adjourned from time to
         time, without further notice.

                  (e) Secured Party may, on a royalty-free basis, use and
         license use of any trademark, trade name, trade style, copyright,
         patent or technical knowledge or process owned, held or used by any
         Debtor in respect of any Collateral as to which any right or remedy of
         Secured Party is exercised or enforced.

In addition, each holder of any Secured Obligation may exercise and enforce such
rights and remedies for the collection of such Secured Obligation as may be
available to it by law or agreement.

                  SECTION 6.2 Remedies Cumulative. Secured Party may exercise
and enforce each right and remedy available to it upon the occurrence of an
Event of Default either before or concurrently with or after, and independently
of, any exercise or enforcement of any other right or remedy of Secured Party or
any holder of any Secured Obligation against any person, entity or property. All
such rights and remedies shall be cumulative, and no one of them shall exclude
or preclude any other.

                  SECTION 6.3 Surplus; Deficiency. Any surplus proceeds of any
sale or other disposition of Collateral by Secured Party remaining after all the
Secured Obligations are indefeasibly paid in full and discharged shall be paid
over to the Debtors or to whomever may be lawfully entitled to receive such
surplus or as a court of competent jurisdiction may direct, except that if any
contingent, unliquidated or unmatured Secured Obligation then remains
outstanding, such surplus proceeds may be retained by Secured Party and held as
Collateral until such time as all outstanding Secured Obligations have been
determined, liquidated and indefeasibly paid in full and discharged. The Debtors
shall be and remain liable for any deficiency.
<PAGE>
                  SECTION 6.4 Information Related to Collateral. If Secured
Party determines to sell or otherwise dispose of any Collateral, the Debtors
shall, and shall cause any person controlled by any Debtor to, furnish to
Secured Party all information Secured Party may request that pertains or could
pertain to the value or condition of such Collateral or would or might
facilitate its sale.

                  SECTION 6.5 Sale Exempt from Registration. Secured Party shall
be entitled at any such sale, if it deems it advisable to do so, to restrict the
prospective bidders or purchasers to persons who will provide assurances
satisfactory to Secured Party that they may be offered and sold the Collateral
to be sold without registration under the Securities Act of 1933, as amended
(the "Securities Act"), or any other applicable state or federal statute, and
upon the consummation of any such sale, Secured Party shall have the right to
assign, transfer and deliver to the purchaser or purchasers thereof the
Collateral so sold. Secured Party may solicit offers to buy the Collateral, or
any part of it, from a limited number of investors deemed by Secured Party, in
its commercially reasonable judgment, to meet the requirements to purchase
securities under Regulation D promulgated under the Securities Act (or any other
regulation of similar import). If Secured Party solicits such offers from such
investors, then the acceptance by Secured Party of the highest offer obtained
therefrom shall be deemed to be a commercially reasonable method of disposition
of the Collateral.

                  SECTION 6.6 Registration Rights. If Secured Party determines
that registration of any securities constituting Collateral under the Securities
Act or other applicable law is required or desirable in connection with any
foreclosure sale, each Debtor will use its best efforts to assist and cooperate
in all respects reasonably requested by Secured Party or Newco Group in causing
such registration to become effective and to be kept effective for such time as
may be reasonably necessary in the opinion of Secured Party, except that no
Debtor shall be obligated under this Section 6.6 to exercise any registration
rights that may be available to it with respect to Newco Common Stock.

hereby, as Trustee under the Collateral Trust Agreement. The provisions of the
Collateral Trust Agreement and all rights, powers, immunities and indemnities
granted to the Trustee under the Collateral Trust Agreement shall apply in
respect of such execution, delivery and acceptance and in respect of any and all
actions taken or omitted by Secured Party under, in connection with or with
respect to this Agreement.
<PAGE>
                  SECTION 7.2 No Liability. Secured Party makes no statement,
promise, representation or warranty whatsoever, and shall have no liability
whatsoever, to any holder of any Secured Obligations as to the authorization,

or as to the creation, perfection, priority or enforceability of any security
interest granted hereunder or as to existence, ownership, quality, condition,
value or sufficiency of any Collateral or as to any other matter whatsoever.

                  SECTION 7.3 Holders Bound. Except where the consent of others
may be required pursuant to the express provisions of the Collateral Trust
Agreement, any modification, amendment, waiver, termination or discharge of any
security interest, right, remedy, power or benefit conferred upon Secured Party
hereby that is effectuated in a writing signed by Secured Party shall be binding
upon all holders of Secured Obligations if it is authorized in the Collateral
Trust Agreement or directed in writing by Newco Group.

                  SECTION 7.4 Duty of Care. Neither Secured Party nor any
director, officer, employee, attorney or agent of Secured Party shall be
obligated to care for the Collateral hereunder or to collect, enforce, vote, or
protect the Collateral or any rights or interests of any Debtor related thereto
or to preserve or enforce any rights which any Debtor or any other Person may
have against any third party, except only that Secured Party shall exercise
reasonable care in physically safekeeping any item of Collateral that was
delivered into Secured Party's possession. Secured Party shall be deemed to have
exercised such reasonable care if the Collateral is accorded treatment
substantially equal to that which Secured Party accords to its own property or
if it selects, with reasonable care, a custodian or agent to hold such
collateral for Secured Party's account.


                                  ARTICLE VIII

interests created under the Collateral Trust Agreement nor any power, privilege,
right or remedy of Secured Party relating thereto, nor the beneficial interest
of Newco Group and other holders of Secured Obligations therein and thereunder
shall at any time in any way be prejudiced, affected or impaired by any act or
failure to act on the part of any of the Debtors or by any act or failure to act
on the part of Secured Party or Newco Group or any other holder of Senior
Secured Obligations or by any breach or default by any of them in the
<PAGE>
performance or observance of any promise, covenant or obligation enforceable by
any Debtor, regardless of any knowledge thereof that Secured Party or Newco

Party shall not be obligated to perform any such duties or obligations and shall

given shall operate as a waiver in respect of any other matter or in respect of
the same matter on a future occasion. Acceptance of or acquiescence in a course

any other application, shall not be in any way affected or impaired thereby and
such other provisions and applications shall be enforceable to the fullest
extent lawful.
