ITEM 5.     OTHER EVENTS.
- ------      --------------

     Pursuant to an Asset Purchase Agreement, dated as of January 22, 1999,
among the Registrant, PRIMESTAR Partners, L.P., a Delaware limited partnership
which is a wholly-owned subsidiary of the Registrant ("PLP"), PRIMESTAR MDU,
Inc., a wholly-owned subsidiary of the Registrant, certain stockholders of the
Registrant (the "Stockholders") and Hughes Electronics Corporation ("Hughes"),
the Registrant has agreed to sell to Hughes its medium-power direct broadcast
satellite business and assets for approximately $1.32 billion in cash and stock
(the "Medium Power Agreement"). Pursuant to the Medium Power Agreement, the
aggregate purchase price for the medium power DBS assets will be comprised of
$1.1 billion in cash and 4,871 million shares of General Motors Class H common
stock. PRIMESTAR will be responsible for the payment of certain working capital
obligations not assumed by Hughes, satisfaction of its funded indebtedness and
costs currently estimated at $350 million associated with the termination of its
high-power business strategy and sale of its medium-power assets to Hughes.

     The closing of the sale of the Registrant's medium-power business and 
assets is subject to various consents from PRIMESTAR's lenders, regulatory 
approvals and other customary conditions. In addition, consummation of the sale
to Hughes of the medium power business is subject to the successful 
restructuring of the Registrant's indebtedness.

     If the proposed transaction with Hughes is not consummated for any reason, 
PRIMESTAR currently intends to operate the medium-power business, which may 
require the restructuring or refinancing of certain of its liabilities.

     In a separate transaction (the "High Power Transaction") and pursuant to an
Asset Purchase Agreement, dated as of January 22, 1999, among the Registrant,
PLP, the Stockholders, Tempo Satellite, Inc. ("Tempo") and Hughes, the
Registrant has agreed to sell to Hughes its rights to acquire Tempo's high-power
satellite assets in a transaction valued at $500 million (the "High Power
Agreement").  The closing of the High Power Transaction is subject to regulatory
approvals and other customary conditions.

     The foregoing description in this Current Report on Form 8-K is qualified
in its entirety by the complete text of the Medium Power Agreement and the High
Power Agreement which are filed as exhibits hereto.

Transferred Assets will exclude, and the Sellers will retain, the Excluded
Assets.

          (c)  Anything contained herein to the contrary notwithstanding, this
Agreement will not constitute an assignment, an attempted assignment or an
agreement to assign any Contract, Lease or License if an assignment or attempted
assignment of the same without the Consent of any other party or parties thereto
would constitute a breach thereof or in any way impair the rights of Sellers or
Buyer 


                                      19

thereunder. Each Seller will use its commercially reasonable efforts (at such
Seller's expense), and Buyer will cooperate (it being understood that such
cooperation will not include any requirement to pay any consideration, agree to
any undertaking or Contract modification or offer or grant any financial
accommodation in excess of any amount payable after the Closing under existing
Contracts) in all reasonable respects with such Seller to obtain prior to the
Closing all Consents and to resolve all impracticalities of assignments or
transfers necessary to sell, assign, convey, transfer and deliver to Buyer or
Newco (if Buyer so elects) the Transferred Assets.  If any such Consent is not
obtained or if an attempted assignment would be ineffective or would impair such
Sellers's, Buyer's or Newco's rights under any such Contract, Lease or License
so that Buyer or Newco (if Buyer so elects) would not receive all such rights,
then (1) such Seller will (x) ensure that the full benefits of any such
Contract, Lease or License are provided or caused to be provided to Buyer or
Newco (if Buyer so elects), and (y) pay promptly or cause to be paid promptly to
Buyer or Newco (if Buyer so elects) when received all monies and other
properties received by such Seller or any of its Affiliates with respect to any
Contract, Lease or License of which Buyer (or Newco) would have been entitled to
receive such monies and other properties if such Consent had been obtained; and
(2) in consideration of Sellers providing or causing to be provided to Buyer or
Newco (if Buyer so elects) the full benefits thereof, Buyer or Newco will
perform and discharge on behalf of such Seller all of such Seller's liabilities,
obligations or commitments thereunder which are Assumed Liabilities described in
Section 3.1 in accordance with the provisions thereof.  In addition, such Seller
- -----------                                                                     
will take such other actions (at such Seller's expense) as may reasonably be
requested by Buyer or Newco (if Buyer so elects) in order to place Buyer,
insofar as reasonably possible, in the same position as if such Contract, Lease
or License had been transferred as contemplated hereby and so that all the
benefits relating thereto, including possession, use, potential for gain and
dominion, control and command, shall inure to Buyer or Newco (if Buyer so
elects), subject to the assumption by Buyer of all obligations and risks that
arise after the Closing Date and through the Shutdown Date with respect to such
Contract, Lease or License, including all risks of loss thereunder.  For
purposes of clarity, if, despite having used commercially reasonable efforts, a
program services provider shall require that as a condition of such Consent,
Buyer agree to carry another service of such program services provider, Seller
shall not be deemed to have breached its obligations under this Section 2.1(c)
                                                                --------------
regardless of whether Buyer elects to accept or reject such requirement.
Notwithstanding the foregoing, if any such Consent is not obtained prior to the
Closing, such Seller will continue to use its commercially reasonable efforts
(at such Seller's expense) to obtain all such Consents (and, if and 

                                      20
<PAGE>
 
when such Consents are obtained, the transfer of the applicable Contract, Lease
or License will be effected in accordance with the terms of this Agreement).

          (d) Owing to the possible applicability of confidentiality
obligations, Sellers and Buyer acknowledge that Buyer has not been afforded an
opportunity to review the Sellers' programming Contracts and the GI Contract.
Sellers covenant to use all commercially reasonable efforts to obtain as
promptly as possible all Consents that may be required to allow Buyer access to
such Contracts.  For a period of thirty (30) days from the date of notice to
Buyer of the receipt of each such Consent, Buyer shall be allowed to review such
Contract so as to ascertain whether it wishes to treat such Contract as a
Transferred Asset or an Excluded Contract.  Sellers will promptly advise Buyer
of the receipt of each such Consent.  Buyer will advise Sellers prior to the
Closing Date which of such Contracts will be Transferred Assets, and all others
will be Excluded Contracts.  These Contracts are subject to the following
provisions:

          (i)  Notwithstanding anything herein to the contrary, if the terms or
     provisions of any programming Contract would be applicable after the
     Closing Date to any of the operations or service offerings of Buyer or its
     Affiliates (as the assignee of such Contract) other than the medium power
     DBS system acquired from Sellers pursuant hereto, such programming Contract
     shall constitute an Excluded Contract unless the same is expressly assumed
     by Buyer pursuant to an instrument of transfer specific to such Contract.
 
          (ii) If Buyer determines in accordance with this Section 2.1(d) that
                                                           --------------     
     the GI Contract will constitute an Excluded Contract, Sellers will
     nevertheless (x) ensure that the full benefits of the GI Contract provided
     to Primestar on the Closing Date, including with respect to those
     provisions regarding conditional access and refurbishment, are provided or
     caused to be provided to Buyer or Newco (if Buyer so elects) from and after
     the Closing Date and through the Shutdown Date and (y) pay promptly or
     cause to be paid promptly to Buyer or Newco (if Buyer so elects) when
     received any monies and other properties received by such Seller or any of
     its Affiliates with respect to the GI Contract which Buyer (or Newco) would
     have been entitled to receive had the GI Contract been a Transferred Asset.

          Section 4.1  Purchase Price.  Subject to the terms and conditions set
                       --------------                                          
forth herein, in consideration for the sale, assignment, conveyance, transfer
and delivery of the Transferred Assets, Buyer will, at the Closing, assume the
Assumed Liabilities and deliver to Primestar the following consideration (the
"Purchase Price"):

          (a) the payment, by wire transfer of immediately available funds to a
bank account designated by Primestar, of an amount equal to One Billion One
Hundred Million Dollars ($1,100,000,000), plus any amounts payable by Buyer to
Sellers pursuant to Section 4.2 or less any amount payable by Sellers to Buyer
                    -----------                                               
pursuant to Section 4.2; and
            -----------     

          (b)  the Parent Securities.

          Section 4.2  Adjustment of Purchase Price.  (a)  At least ten (10)
                       ----------------------------                         
Business Days prior to the Closing Date, Sellers shall deliver to Buyer a
certificate (the "Preliminary Working Capital Certificate") signed by the Chief
Financial Officer of each Seller setting forth an itemized estimate of Sellers'
Net Working Capital as of the Closing Date.  The Preliminary Working Capital
Certificate shall be delivered together with such supporting data as may be
reasonably necessary for Buyer to verify the information set forth in the
Preliminary Working Capital Certificate (including, in the case of Primestar
Inventory, a detailed listing by item and location).  Buyer's representatives
shall be entitled to review such supporting data and shall have full access to
all books, records and other documents used in the preparation of the
Preliminary Working Capital Certificate by Seller.  Between the date of delivery
of the Preliminary Working Capital Certificate and the Closing Date, Sellers
shall make such adjustments to the data set forth in the Preliminary Working
Capital Certificate as are appropriate, based on information then reasonably
available to it, to bring such data down to the Closing Date, shall keep Buyer
advised of all such adjustments proposed to be made, and two Business Days prior
to the Closing Date, Sellers shall deliver to Buyer a revised certificate (the
"Estimated Working Capital Certificate") signed by the Chief Financial Officer
of each Seller reflecting all such adjustments, 


                                      24
<PAGE>
 
together with supporting data. For purposes of the Closing, but without
prejudice to any party's rights under this Section 4.2(a), Net Working Capital
                                           --------------
and the Working Capital Adjustment (as defined below) shall be calculated in
accordance with the data set forth in the Estimated Working Capital Certificate.

          (i)   If the Net Working Capital as specified in the Estimated Working
Capital Certificate (the "Estimated Net Working Capital Amount") is a positive
number, then Buyer shall pay to Seller on the Closing Date, in cash, the amount
of the Estimated Net Working Capital Amount, as additional consideration for the
Transferred Assets; if the Estimated Net Working Capital Amount is a negative
number, then Seller shall pay to Buyer, in cash, the absolute value of the
Estimated Net Working Capital Amount, in both cases by adjustment to the
Purchase Price as provided in Section 4.1(a).
                              -------------- 

          (ii)  Not later than ninety (90) days following the Closing Date,
Buyer shall deliver to Sellers a certificate (the "Final Working Capital
Certificate") signed by the Vice President, Controller of Buyer setting forth an
itemized statement of Seller's Net Working Capital as of the Closing Date. The
Final Working Capital Certificate shall be delivered together with such
supporting data as may be reasonably necessary for Sellers to verify the
information set forth in the Final Working Capital Certificate (including, in
the case of Primestar Inventory, a detailed listing by item and location).
Sellers' representatives shall be entitled to review such supporting data and
shall have full access to all books, records and other documents used in the
preparation of the Final Working Capital Certificate by Buyer.

          (iii) During the 60-day period following the delivery of the Final
Working Capital Certificate, Buyer and Sellers will in good faith attempt to
agree upon such adjustments, if any, to the matters set forth in the Final
Working Capital Certificate as are necessary or appropriate to reflect all
information then available which is relevant to the calculation of Net Working
Capital as of the Closing Date. During such period, each party shall provide the
other with such additional backup information and access to relevant books,
records and documents as may reasonably be requested.  If on or before the last
day of such 60-day period, Sellers notify Buyer in writing that they dispute the
accuracy of the data set forth in the Final Working Capital Certificate and that
such dispute has not been resolved (such notice to set forth in reasonable
detail Sellers' recalculation of Net Working Capital as of the Closing Date and
the amount in dispute), such dispute shall promptly be submitted for
determination to a partner in the office of one of the five largest national
accounting firms selected jointly by Buyer and Sellers who has expertise in the
multi-channel 


                                      25

video program distribution industry. The partner in the applicable firm
accepting such assignment is hereinafter referred to as the "Arbiter". In
resolving any disputed item, the Arbiter may not assign a value to any
particular item greater than the greatest value for such item claimed by either
party or less than the smallest value for such item claimed by either party, in
each case, as presented to the Arbiter. Each of Buyer and Sellers covenants and
agrees to cooperate fully with the Arbiter and to provide to the Arbiter such
information, documents and records as he or she may request. The Arbiter shall
be requested to complete his or her determination as soon as possible but in any
event within 90 days after the date of his or her engagement. All decisions of
the Arbiter shall be final and binding on the parties hereto. Any difference
between the amount of Net Working Capital presented in the Final Working Capital
Certificate, whether agreed to by the Buyer and Sellers, or determined by the
Arbiter, and the amount of Net Working Capital presented in the Estimated
Working Capital Certificate shall be settled as follows: If the Final Net
Working Capital is greater than the Estimated Net Working Capital, then Buyer
shall pay Sellers, in cash, the resulting difference; if the Final Net Working
Capital is less than the Estimated Net Working Capital, then Sellers shall pay
Buyer, in cash, the resulting difference. Any amounts owed to a party pursuant
to the preceding sentence shall be paid by the other party by wire to a United
States bank account designated by the owed party, together with interest thereon
at the prime rate or its equivalent announced by Citibank, N.A. from time to
time from the Closing Date to the date of payment.

          (iv)  The Arbiter shall have authority to charge either party with the
fees and costs of the Arbiter if the Arbiter finds such allocation to be
justified.  In all other cases Buyer and Sellers shall each bear one-half of the
fees and costs of the Arbiter, and each party shall bear its own costs incurred
in connection with the submission of such disputes to the Arbiter.

          Section 4.3  Allocation of Purchase Price.  (a) Not later than 120
                       ----------------------------                         
days after the Closing Date, Buyer shall provide to Primestar (on behalf of
Sellers) copies of Form 8594 and any required exhibits thereto (the "Asset
Acquisition Statement") with Buyer's proposed allocation of the purchase price
paid by Buyer with respect to the Transferred Assets.  Within 20 days after the
receipt of such Asset Acquisition Statement, Primestar shall propose to Buyer
any changes to such Asset Acquisition Statement or shall indicate its
concurrence therewith, which concurrence shall not be unreasonably withheld.
Thereafter, Buyer shall provide to Primestar from time to time revised copies of
the Asset Acquisition Statement (the "Revised Statements") so as to report any
matters on the Asset Acquisition Statement that need updating 


                                      26
<PAGE>
 
(including purchase price adjustments, if any). Within 20 days after the receipt
of any Revised Statement, Primestar shall propose to Buyer any changes to such
Revised Statement or shall indicate its concurrence therewith, which concurrence
shall not be unreasonably withheld. Primestar's failure to notify Buyer of any
objection to the Asset Acquisition Statement or a Revised Statement within 20
days after the delivery thereof shall constitute Sellers' concurrence therewith.
Subject to and in accordance with Section 4.3(b) below, Buyer and Primestar
                                  --------------                           
shall endeavor in good faith to resolve any differences with respect to the
Asset Acquisition Statement or any Revised Statements within 20 days after
Buyer's receipt of notice of objections or suggested changes from Primestar. The
costs of preparing the Asset Acquisition Statement and any supporting materials
(including any appraisals) shall be borne equally by Buyer and Primestar.

     (b)  Subject to the provisions of the following sentence of this Section
                                                                      -------
4.3(b), the Purchase Price for the Transferred Assets shall be allocated in
- ------                                                                     
accordance with the Asset Acquisition Statement or, if applicable, the last
Revised Statement, provided by Buyer to Primestar pursuant to Section 4.3(a)
                                                              --------------
above, and subject to the requirements of any applicable Tax law or election,
all Tax returns and reports filed by Buyer and Sellers shall be prepared
consistently with such allocation.  If Primestar (on behalf of Sellers) shall
have withheld its consent to such allocation (which consent shall not be
unreasonably withheld) and Buyer and Primestar have acted in good faith to
resolve the differences with respect to the items on the Asset Acquisition
Statement or any Revised Statement for a period of 20 days after Buyer's receipt
of notice of objections or suggested changes from Primestar and, within such 20-
day period, Buyer and Primestar are unable to resolve such differences which, in
the aggregate, are material in relation to the Purchase Price for the
Transferred Assets, (i) Buyer and Primestar shall, subject to the requirements
of any applicable Tax law or election, file all Tax returns and reports in a
manner consistent with the allocation provided in such statements and (ii) Buyer
and Primestar shall refer any issues as to which such differences exist to an
independent accounting firm mutually acceptable to Buyer and Primestar for
resolution which shall resolve such issues within 30 days of the date submitted
and whose resolution shall be final and binding on the parties hereto.  The fees
and expenses of such accounting firm shall be borne equally by Buyer and
Primestar.

used in the Business have been maintained and repaired for their continued
operation and are in good operating condition, reasonable wear and tear

contemplated by this Agreement until the Closing Date, such Seller and its
Affiliates shall not, nor shall such Seller or its Affiliates authorize or
permit any officer, director or employee of, or any investment banker, attorney,
accountant, or other representative retained by, such Seller or such Affiliates
to, directly or indirectly, solicit, initiate, encourage or entertain (including
by way of furnishing information) discussions, inquiries, offers or proposals or
participate in any discussions or negotiations for the purpose or with the
intention of leading to any proposal or offer from any Person which constitutes
or concerns, or may reasonably be expected to lead to, any transaction involving
any proposal or offer to acquire all or any portion of the Transferred Assets.
Such Seller shall promptly (and in any event within two Business Days) notify
Buyer in writing of any inquiry they receive from any Person (and shall set
forth in such notice the identity of such Person) with respect to the subject
matter of the first sentence of this Section 9.2.  Each Seller will immediately
                                     -----------

                       ------------------------------                           
will any of them permit any of their respective Affiliates to take or agree or

be expected to result in any of its representations and warranties hereunder
being untrue.

          Section 9.4. Access to Information.
                       --------------------- 

          (a) From the date of this Agreement through the Closing Date, each
Seller shall afford to Buyer and its representatives free and full access at all
reasonable times to the properties, personnel, books and records (including
Material Contracts, marketing materials and customer satisfaction reports)
relating to the Transferred Assets and the Assumed Liabilities (such access not
to unreasonably interfere with the business of any Seller) in order that the
Buyer and its representatives may have full opportunity to make such
investigations as they may reasonably desire to make of all matters relating to
the transactions contemplated 

                                      51

hereunder. Any proprietary information provided pursuant to this Section 9.4(a)
                                                                 --------------
shall be kept confidential by Buyer and shall not be revealed to any Person
other than the respective officers, directors, employees, agents and
representatives of such parties (it being agreed that Buyer shall be liable for
any breach of this Section 9.4(a) by any of its officers, directors, employees,
                   --------------              
agents and representatives), except to the extent such information (i) is or
becomes generally available to the public (other than as a result of a breach of
this Section 9.4(a) by Buyer), (ii) was previously known by Buyer, (iii)
     --------------                    
hereafter is disclosed to Buyer without restrictions on its use by a Person who,
to the Knowledge of Buyer, is not bound by an agreement of confidentiality with
any Seller with respect thereto; or (iv) is required to be disclosed under any
applicable Law or under subpoena or other legal process. No such investigation
shall diminish in any respect any of the representations or warranties of any
Seller or Buyer's rights in respect of any inaccuracy or breach thereof. The
parties hereto shall be entitled to seek injunctive relief or such other remedy
as may be available at law or in equity for any breach by another party of this
Section 9.4(a).
- -------------- 

          (b) Between the date hereof and the Closing Date, Primestar shall
furnish to Buyer (i) within two Business Days after the delivery thereof to
management, such monthly financial statements and data as are regularly prepared
for distribution to Primestar's Chief Executive Officer and/or the Stockholders
and (ii) at the earliest time at which they are available and prior to filing
thereof with the SEC, such quarterly and annual financial statements as are
prepared for Primestar's SEC filings, which shall be in accordance with the
books and records of Primestar, and drafts of all such SEC filings.

          (c) Buyer will hold and will cause its consultants and advisors to
hold in confidence all documents and information concerning Primestar and its
Subsidiaries furnished to Buyer in connection with the transactions contemplated
by this Agreement to the extent required by the Confidentiality Agreement.

 
          (d) For a period of four years beginning on the Closing Date, Buyer
agrees to make available to each Seller and its representatives, at reasonable
times and at such Seller's expense and in a manner that will not unreasonably
interfere in any material respect with Buyer's business (and such Seller shall
enter into an appropriate confidentiality agreement with Buyer in connection
therewith): (i) personnel of Buyer (including Transferred Employees) and (ii)
books and records of the Business through the Closing Date, including the
Records, in each case, as necessary in order to assist Seller and its Affiliates
in (i) making all required or appropriate regulatory filings and 

                                      52

other reports relating to the Excluded Assets, Excluded Contracts and Excluded
Liabilities or (ii) defending against or asserting claims arising out of or
relating to the Excluded Assets, Excluded Contracts and Excluded Liabilities.

          Section 9.5. Notices and Consents.  Buyer shall give all required
                       --------------------                                
notices to third parties, and shall use its commercially reasonable efforts to
obtain any material third-party Consents that may be required, in connection
with the transactions contemplated by this Agreement.  Each Seller shall give
all required notices to third parties, and shall use its commercially reasonable
efforts to obtain all required Consents, including all required Consents of
Governmental Entities and bondholders or lenders of Primestar or any of its
Affiliates, and any other material third-party Consents that may be required or
that Buyer reasonably may request, in connection with the transactions
contemplated by this Agreement.  Within five Business Days following the date of
this Agreement (but in no event prior to approval of this Agreement by the Board
of Directors of GM), Buyer and each Seller shall file any Notification and
Report Forms and related materials that it may be required to file with the FTC
and the Antitrust Division of the United States Department of Justice (the
"Antitrust Division") under the HSR Act, and shall make any further filings
pursuant thereto that may be necessary, proper or advisable.   As promptly as is
practicable after the date of this Agreement, Buyer and each Seller shall take
any additional action in connection with any other Consents of, to or with any
Governmental Entities and third parties that it may be required to give, make or
obtain and shall refrain from taking any action the purpose or effect of which
could reasonably be expected to make it less likely that such Consents will be
given, made or obtained on the terms provided for in this Agreement. Without
limiting the generality of the foregoing, Buyer and each Seller shall: (i)
cooperate in all respects with each other in connection with any filing,
submission, adversarial proceeding or the timing thereof; (ii) in connection
with any investigation or other inquiry, including any proceeding initiated by a
private party, keep the other parties hereto informed on a timely basis of any
material communication received by such party from, or given by such party to,
the FTC, the Antitrust Division, the FCC or any other Governmental Entity and of
any material communication received or given in connection with any Action by a
private party, in each case regarding any of the transactions contemplated by
this Agreement, and permit any other party hereto to preview any material
communication given by or to it; and (iii) consult with each other, in advance
of any meeting or conference with such Governmental Entities or in connection
with any Action by a private party.  Buyer and each Seller will use their
commercially reasonable efforts to obtain such approvals as promptly as possible
and, in this regard, provide all information reasonably requested, assist and
cooperate with 

                                      53
<PAGE>
 
one another to make the necessary filings and take such steps as may be
necessary to secure the non-objection of the relevant antitrust and regulatory
authorities.

          Section 9.6. Notification of Certain Matters.  Each Seller, on the one
                       -------------------------------                          
hand, and Buyer, on the other, shall give prompt notice to each other of (i) the
occurrence or nonoccurrence of any event the occurrence or nonoccurrence of
which would be likely to cause any representation or warranty contained in this
Agreement to be untrue or inaccurate in any material respect at or prior to the
Closing Date, (ii) any material failure of a party hereto to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder, (iii) any notice of, or other communication relating to, a default
or event which, with notice or lapse of time or both, would become a default,
received by a party  hereto or any of its Subsidiaries subsequent to the date of
this Agreement and prior to the Closing Date, under any contract or agreement
material to the financial condition, properties, businesses or results of
operations of a party hereto and its Subsidiaries taken as a whole to which it
or any of its Subsidiaries is a party or is subject, (iv) any notice or other
communication from any third party alleging that the consent of such third party
is or may be required in connection with the transactions contemplated by this
Agreement, or (v) any Material Adverse Effect on a party hereto; provided, that
                                                                 --------      
the delivery of any notice pursuant to this Section 9.6 shall not cure such
                                            -----------                    
breach or non-compliance or limit or otherwise affect the remedies available
hereunder to Buyer.

          Section 9.7. Public Announcements.  No press release or announcement
                       --------------------                                   
concerning the transactions contemplated hereby will be issued by any party
hereto without the prior consent of the other parties hereto, except as such
release or announcement may be required by Law in which case the party required
to make the release or announcement will allow the other party reasonable time
to comment on such release or announcement in advance of such issuance.

          Section 9.8. Employee Matters.   (a)  Transferred Employees.  Prior to
                       ----------------         ---------------------           
the Closing Date, Buyer shall provide Primestar with a list of employees of the
Sellers to whom Buyer proposes to offer employment effective as of the Closing
Date ("Potential Transferred Employees").  With respect to each Potential
Transferred Employee who accepts employment with Buyer as of the Closing Date or
Transition Employee who accepts employment with Buyer during his or her
Transition Period (each a "Transferred Employee" and, collectively "Transferred
Employees"), Buyer shall provide such employee with:  (i) vacation and sick
leave to the extent accrued, unused and reflected in Working Capital Liabilities
as of the Closing Date, (ii) past service credit for eligibility and vesting
purposes under the Buyer's employee welfare 

                                      54
<PAGE>
 
benefit plans and 401(k) plan for their period of employment on record with the
Sellers and (iii) past service credit for vesting only under the Buyer's "Non-
Bargaining Retirement Plan" for their period of employment on record with the
Sellers; provided, that such service recognition does not result in any 
         --------           
duplication of benefits. Each Transferred Employee who completes one year of
employment during which the Transferred Employee completed 1,000 hours of
service with Buyer shall accrue a benefit under the Buyer's "Non-Bargaining
Retirement Plan" with respect to such year. Each such Transferred Employee shall
be credited, in accordance with the terms of the Buyer's "Non-Bargaining
Retirement Plan", only with his or her period of employment with the Buyer for
eligibility for early retirement subsidies under such plan. Past service credit
for employment with the Sellers shall not be granted for purposes of benefit
accrual and early retirement subsidies. Individuals who terminate their
employment with the Sellers prior to the Closing Date and are subsequently hired
by Buyer shall not be entitled to any past service recognition under this 
Section 9.8.
- ----------- 

          (b)  Transition Employees.  Within 30 days after the date hereof,
               --------------------                                        
Buyer shall notify Primestar in writing of the names of any of the employees of
the Sellers which Buyer would like the Sellers to continue to employ after the
Closing Date ("Potential Transition Employees"), but in no event beyond a date
specified in writing by Buyer within six months following the Closing Date
("Wind-up Date").  Buyer may revise its list of Potential Transition Employees
at any time.  Potential Transition Employees who remain actively employed on the
Closing Date (including employees absent solely by reason of vacation, but
excluding employees absent for any other reason) shall constitute "Transition
Employees," and Seller shall continue to employ and to make available to Buyer
the services of each such employee from the Closing Date through the earlier of
(i) the Wind-up Date or (ii) with respect to any such employee, any date
designated in a written notice provided by Buyer to Sellers, at least 30
calendar days prior to such date ("Transition Period").  The Transition Period
need not be the same for each Transition Employee, and the provision for 30 days
prior notice by Buyer of its termination of any Transition Employee's services
shall not be required if such termination is for "cause" (as determined by Buyer
in good faith in accordance with its policies with respect to its employees).

          (c)  Buyer shall promptly reimburse the Sellers for the salary and
Benefit Plan payments (excluding payments relating to stock option, stock
purchase, stock appreciation, bonus or other incentive compensation, relocation
benefits, and similar plans or arrangements) arising solely from the employment
of Transition Employees during their respective Transition Periods; provided,
however, that Buyer 

                                      55
<PAGE>
 
shall not be liable or otherwise responsible for: (i) any increases in salary or
wage rates granted after the date hereof, (ii) any costs relating to changes to
the Benefit Plans after the Closing Date, (iii) severance benefits and (iv) any
payments arising from the employment of Transition Employees by Sellers before
or after the applicable Transition Period. Notwithstanding the preceding
sentence, to the extent a Benefit Plan is covered by an insurance policy, Buyer
shall reimburse the Sellers for the applicable premiums (and not benefit
payments), net of employee contributions. Sellers shall not be obligated to re-
hire or take any other action with respect to Transition Employees who resign
from employment with the Sellers prior to the Closing Date.

          (d)  Sellers specifically acknowledge and agree that they shall be
exclusively responsible for any and all Liabilities arising under Workers
Adjustment and Retraining Notification Act or Part 6, Title I of ERISA (COBRA),
or similar Laws with respect to their employees, including Transferred Employees
and Transition Employees, with respect to their termination of employment with
the Sellers and such employees' eligible dependents and beneficiaries.

          (e)  Notwithstanding the foregoing, Sellers shall be responsible for
all severance benefits paid or payable with respect to any employee of Buyer,
whose employment is terminated prior to the first anniversary of the Closing
Date and for any employee of Seller (including any Transition Employee) whose
employment is terminated at any time.  Buyer shall be responsible for all
severance benefits paid or payable with respect to any Transferred Employee
whose employment is terminated at any time beginning the day after the first
anniversary of the Closing Date.

          (f)  Primestar will consult with Buyer in good faith in determining
which employees should receive Stay Bonuses.  If the Closing occurs and Seller
complies with such obligation, Buyer agrees to reimburse the Sellers (or, at
Buyer's option, increase the Purchase Price by the amount of such Stay Bonus)
for any Stay Bonuses paid to its employees after and for employment with Sellers
through April 1, 1999, but in no event shall Buyer be obligated to reimburse
Sellers for (i) the amount of any Stay Bonus for any employee exceeding the
applicable amount set forth in the most recent Stay Bonus plan document provided
to Buyer prior to the date hereof or (ii) more than $2 million in the aggregate.
Primestar represents to Buyer that as of the date hereof the amount of Stay
Bonuses it is considering offering would be between $1.8 million and $2.5
million in the aggregate.

          (g)  Solicitation of Employees. Sellers, the Stockholders and their
               -------------------------                                     
respective Affiliates shall not solicit or assist any other Person to solicit
for employment or otherwise offer employment to:

          (i) any employees of the Sellers for the period from the date hereof
     through and including the thirtieth (30th) day following the Closing Date;

          (ii) any Potential Transition Employees, Potential Transferred
     Employees or Transition Employees prior to the 60th day following the later
     of the Closing Date or the date any such employee first becomes a
     Transition Employee, if at all; and

          (iii)  any Transferred Employee prior to the second anniversary of the
     Closing Date;

provided, however, that Sellers and Buyer shall reasonably cooperate in good
- --------  -------                                                           
faith to identify those Transition Employees whose services are essential to the
efficient, effective and orderly transfer of the Business to Buyer and
thereafter the operation of the Business by Buyer and that Sellers, the
Stockholder and their respective Affiliates shall not induce any such employees
to terminate their employment prior to the end of their Transition Period if
such termination would materially disrupt the efficient, effective and orderly
transfer of the Business to Buyer.

          Section 9.9  Tax Matters.  Each Seller and Buyer shall cooperate fully
                       -----------                                              
with each other and make available or cause to be made available to each other
in a timely fashion such Tax data, prior Tax returns and filings and other
information as may be reasonably required for the preparation by Buyer or such
Seller of any Tax returns, elections, consents or certificates required to be
prepared and filed by Buyer or such Seller and any audit or other examination by
any taxing authority, or judicial or administrative proceeding relating to
liability for Taxes in connection with the transactions contemplated hereby.
Seller will retain and provide to Buyer all records and other information which
may be relevant to any such Tax return, audit or examination, proceeding or
determination, and will provide Buyer with any final determination of any such
audit or examination, proceeding or determination that affects any amount
required to be shown on any Tax return of the other party for any period.
Without limiting the generality of the foregoing, Seller will retain copies of
all Tax returns, supporting work schedules and other records relating to Tax
periods or portions thereof ending prior to or on the Closing Date.

          Section 9.10. Commercially Reasonable Efforts; Further Assurances.
                        --------------------------------------------------- 

          (a) Each of Buyer and Seller will use its commercially reasonable
efforts to cause to be fulfilled the conditions to the respective obligations of
the other party set forth in Article X and Sellers agree to use all commercially
reasonable efforts to satisfy the Debt Tender Condition as promptly as
practicable after the date hereof.

          (b) From time to time, as and when requested by either party hereto,
the other party will execute and deliver, or cause to be executed and delivered,
all such documents and instruments and will take, or cause to be taken, all such
reasonable actions, as such other party may reasonably deem necessary or
desirable to consummate the transactions contemplated by this Agreement,
including the orderly transfer and transition of the Transferred Assets to Buyer
or Newco, as the case may be.  None of the parties hereto shall take any action
or fail to take any action which would reasonably be expected to frustrate the
intent and purposes of this Agreement or the transactions contemplated hereby.

          (c) Anything contained in this Agreement to the contrary
notwithstanding, none of the parties hereto will nor will any Affiliate thereof
be required to commence litigation, divest or hold separate any business or
assets or agree to any limitation on such party's or Affiliate's ability to
control in any respect its business or operations in connection with the
consummation of the transactions contemplated by this Agreement.

          Section 9.11. Billing and Customer Management Systems.  Prior to the
                        ---------------------------------------               
Closing Date, Primestar will cooperate with Buyer to facilitate the planning of
the consolidation of billing, customer service and other business support
systems.

          Section 9.12. Bulk Transfer Laws.  Each Seller shall comply with the
                        ------------------                                    
provisions of any bulk transfer and similar laws which may be applicable to the
transactions contemplated by this Agreement.

          Section 9.13. Subscriber List, Etc.
                        ---------------------

          (a) Each Seller and Stockholder agrees not to use or disseminate for
any purpose after the date hereof any Records or other information with respect
to Subscribers (or which would be of assistance in identifying Subscribers) in
the possession of such Stockholder, including not using such information for any

                                      58
<PAGE>
 
marketing activities, including with respect to any direct marketing to such
Subscriber by any multi-channel video program distributor.

          (b) Each Seller and Stockholder agrees to assist Buyer in negotiating
with programming providers to ameliorate the adverse impact of provisions in
programming Contracts that increase the cost per subscriber for such programming
as the number of subscribers declines.

          Section 9.14. Shutdown.  Buyer intends to terminate the provisions of
                        --------                                               
the medium-power service on a day that is the last day of a calendar month
between and including the months of March 2001 and September 2001.  Buyer shall
notify Primestar in writing within 60 days after the Closing Date as to the
Shutdown Date. Notwithstanding any other provisions of this Agreement to the
contrary, Buyer shall only be responsible for Assumed Liabilities with respect
to Contracts assumed by Buyer from the Closing Date through the Shutdown Date.
Sellers shall be responsible for all obligations, covenants and other
Liabilities with respect to such assumed Contracts, including the Shutdown
Liabilities, for all periods beginning on the day after the Shutdown Date;
provided, that no Seller shall be responsible to provide any services to Buyer
- --------                                                                      
with respect to such assumed Contracts for any period beginning after the
Shutdown Date.  In addition, if the actual termination of the medium-power
business occurs on a date other than the Shutdown Date, no Seller shall be
responsible to Buyer for any incremental Liabilities resulting from the
termination on a day other than the Shutdown Date. Buyer agrees to assist
Sellers in negotiating with programming providers to ameliorate the adverse
impact of provisions in programming Contracts which impose on Sellers Shutdown
Liabilities resulting from rebates or repayments made to program services
providers that had previously provided launch support to Seller to the extent
such cooperation would not impact the Business in any adverse respect or result
in any additional expenses by Buyer.

transfer records and may refuse to transfer any Parent Securities not
transferred in compliance therewith or in compliance with the restrictions on
transfer set forth herein.  Each certificate shall be stamped or otherwise
imprinted with a legend in substantially the following form:

               "The shares represented by this Certificate have not been
          registered under the Securities Act of 1933 and may not be transferred
          in the absence of such registration or an exemption therefrom under
          such Act.  Such shares may be transferred only in compliance with the

                                      59
<PAGE>
 
          conditions specified in the Stock Purchase Agreement dated ________,
          1999 between Primestar and Buyer.  A complete and correct copy of such
          Agreement is available for inspection at the principal office of the
          Buyer and will be furnished without charge to the holder of such
          shares upon written request."

          (b)  Primestar and Buyer agree to use commercially reasonable efforts
to enter into the Parent Security Documents as of the Closing Date.  The Parent
Security Documents will provide, among other things, that no Parent Securities
may be transferred prior to the first anniversary of the Closing Date, other
than transfers to the Stockholders in compliance with applicable Law.  Buyer's
parent will provide registration rights to Primestar in connection with the
Parent Securities.  These rights will consist of two demand registration rights
which would only be available if registration under the Securities Act is
required to effectuate the disposition of such securities; such registration
would require notice from the holders of a majority of the Parent Securities.
Buyer's parent will be entitled to defer any such registration for up to six
months if it reasonably determines that registration of the Parent Securities
could materially interfere with business activities or plans of Buyer or Buyer's
parent. Buyer's parent will agree to incur the expenses in connection with any
registration, other than the expenses of counsel to the holders of securities to
be registered thereunder and any underwriting commissions and discounts payable
in connection therewith and, in addition, Buyer's parent will agree to provide
customary indemnification to each holder and the Affiliates thereof and any
underwriters retained by such holders.  Buyer's parent will also be entitled to
select the managing underwriter of any underwritten registered offering, subject
to the consent of such holders (which consent will not be unreasonably
withheld).  Buyer's parent and each holder intending to register its securities
in an underwritten offering will be required to enter into customary
underwriting agreements prior to such sale and provide customary indemnification
to each such holder and their Affiliates, Buyer and the underwriters in
connection with such registration.

          Section 9.16. Power of Attorney with Respect to Assets.  On the
                        ----------------------------------------         
Closing Date, each Seller (at its sole cost and expense) will constitute and
appoint Buyer its true and lawful attorney, with full power of substitution, in
its name and on its behalf but for the benefit of Buyer, to institute and
prosecute all proceedings that Buyer may deem proper in order to collect, assert
or enforce any claim, right or title of any kind in or to the Transferred Assets
or the Assumed Liabilities, or to defend or compromise any Action in respect of
any of such Transferred Assets or Assumed Liabilities, and to take all such
action in relation thereto as Buyer shall deem 


                                      60
<PAGE>
 
advisable. Each such party acknowledges that such powers will be coupled with an
interest and will not be revocable by either of them for any reason. Buyer will
retain for its own account any amount collected as a result of any action taken
pursuant to the foregoing powers.

          Section 9.17 ResNet Communications, LLC and Global Interactive
                       -------------------------------------------------
Communications Corporation.  Primestar represents to Buyer that it has the
- --------------------------                                                
right, prio to April 1, 1999, to exercise, without the payment of any
consideration, an option (the "Option") to cause the sale for cash of its equity
interest in ResNet Communications, LLC or Global Interactive Communications
Corporation, as the case may be (the "Shares"). The parties agree that the
Shares and the Option constitute Transferred Assets for purposes of this
Agreement; provided, however, that Primestar will have the right to exercise the
           --------  -------                                                    
Option prior to the Closing Date (but will not have the right to transfer any of
the Shares or the Option).  If Primestar exercises the Option prior to the
Closing Date, the proceeds therefrom will be shared equally by Primestar and
Buyer. If Primestar does not exercise the Option prior to the Closing Date, the
Shares and the Option will be transferred to Buyer on the Closing Date.  If
Buyer elects after the Closing Date (but prior to the time that the Final
Working Capital Certificate is required to be delivered to Sellers pursuant to
Section 4.2) to exercise the Option, the proceeds therefrom will be shared
- -----------                                                               
equally by Primestar and Buyer.  If Buyer has not exercised the Option prior to
the time that the Final Working Capital Certificate is delivered to the Sellers
pursuant to Section 4.2, the Shares and the Option will be collectively
reflected on the Final Working Capital Certificate as Working Capital Assets
equal to 50% of the consideration which would be received by Buyer were it to
exercise the Option.  Buyer will have the sole right to retain any proceeds
received from transferring the Shares or exercising the Option after the time of
delivery of the Final Working Capital Certificate.

the closing of such transaction (regardless of when the closing thereunder shall
occur). The payment of such amount to Buyer shall be a condition to the entry
into any such transaction by either Seller.  The obligations to pay Buyer the
monies described in this Section 11.2 will be joint and several obligations of
each of the Sellers and the Stockholders.

          Section 13.3. Procedures for Indemnification.
                        ------------------------------ 

          (a) If a claim or demand is made against an Indemnitee, or an
Indemnitee shall otherwise learn of an assertion, by any Person who is not a
party to this Agreement (or an Affiliate thereof) (a "Third Party Claim") as to
which one or more parties (collectively, the "Indemnifying Party") may be
obligated to provide indemnification pursuant to this Agreement, such Indemnitee
will notify the Indemnifying Party in writing, and in reasonable detail, of the
Third Party Claim reasonably promptly after becoming aware of such Third Party
Claim; provided, however, that failure to give such notification will not affect
       --------  -------                                                        
the indemnification provided hereunder except to the extent the Indemnifying
Party shall have been actually prejudiced as a result of such failure.

          (b) If a Third Party Claim is made against an Indemnitee and the
Indemnifying Party unconditionally and irrevocably acknowledges in writing its
obligation to indemnify the Indemnitee therefor (subject to verification that
any losses or costs in respect thereof constitute Damages and compliance with
the other terms hereof), the Indemnifying Party will be entitled to assume the
defense thereof (at the expense of the Indemnifying Party) with counsel selected
by the Indemnifying Party and reasonably satisfactory to the Indemnitee.  Should
the Indemnifying Party so elect to assume the defense of a Third Party Claim,
the Indemnifying Party will not be liable to the Indemnitee for any legal or
other expenses subsequently incurred by the Indemnitee in connection with the
defense thereof; provided that, if in any Indemnitee's reasonable judgment a
conflict of interest exists in respect of such claim, such Indemnitee shall have
the right to employ separate counsel (which shall be reasonably satisfactory to
the Indemnifying Party) and one local counsel to represent such Indemnitee and
in that event the reasonable fees and expenses of each such counsel shall be
paid by such Indemnifying Party.  If the Indemnifying Party assumes the defense
of any Third Party Claim, the Indemnitee shall have the right to participate in
the defense thereof and to employ counsel, at its own expense (except as
otherwise provided in the preceding sentence), separate from the counsel
employed by the Indemnifying Party.  The Indemnifying Party shall be liable for
the fees and expenses of counsel employed by the Indemnitee for any period
during which the Indemnifying Party has failed to assume the defense thereof or
if it does not expressly elect to assume the defense thereof (including
acknowledging its indemnification obligation as aforesaid).  If the Indemnifying
Party assumes the defense of any Third Party Claim, the Indemnifying Party will
promptly supply to the Indemnitee copies of all correspondence and documents
relating to or in connection with such Third Party Claim and keep the Indemnitee
fully informed of all developments relating to or in 

                                      70
<PAGE>
 
connection with such Third Party Claim (including providing to the Indemnitee on
request updates and summaries as to the status thereof). If the Indemnifying
Party chooses to defend a Third Party Claim, all the Indemnitees shall
reasonably cooperate with the Indemnifying Party in the defense thereof (such
cooperation to be at the expense, including reasonable legal fees and expenses,
of the Indemnifying Party).

          (c) If the Indemnifying Party unconditionally and irrevocably
acknowledges in writing its obligation to indemnify the Indemnitee for a Third
Party Claim (subject to verification that any losses or costs in respect thereof
constitute Damages and compliance with the other terms hereof), the Indemnitee
will agree to any settlement, compromise or discharge of such Third Party Claim
which the Indemnifying Party may recommend and which by its terms obligates the
Indemnifying Party to pay the full amount of Damages in connection with such
Third Party Claim and unconditionally and irrevocably releases the Indemnitee
(and the other members of the Buyer Group or the Seller Group, as the case may
be) completely from all Liability in connection with such Third Party Claim,
provided, however, that, without the Indemnitee's prior written consent, the
- --------  -------                                                           
Indemnifying Party shall not consent to any settlement, compromise or discharge
(including the consent to entry of any judgment), and the Indemnitee may refuse
to agree to any such settlement, compromise or discharge that, in the reasonable
opinion of the Indemnitee could reasonably be expected to materially and
adversely affect the Indemnitee.  If the Indemnifying Party unconditionally and
irrevocably acknowledges in writing its obligation to indemnify the Indemnitee
for a Third Party Claim, the Indemnitee shall not (unless required by law) admit
any liability with respect to, or settle, compromise or discharge, such Third
Party Claim without the Indemnifying Party's prior written consent (which
consent shall not be unreasonably withheld).

          (d) Any claim on account of Damages which does not involve a Third
Party Claim shall be asserted by reasonably prompt written notice given by the
Indemnitee to the Indemnifying Party from whom such indemnification is sought.
The failure by any Indemnitee so to notify the Indemnifying Party shall not
relieve the Indemnifying Party from any liability which it may have to such
Indemnitee under this Agreement, except to the extent that the Indemnifying
Party shall have been actually prejudiced by such failure.  If the Indemnifying
Party does not dispute its liability to the Indemnitee with respect to the claim
made in such notice by notice to the Indemnitee prior to the expiration of a 30-
calendar-day period following the Indemnifying Party's receipt of notice of such
claim, the claim shall be conclusively deemed a liability of the Indemnifying
Party under this Agreement.  The Indemnifying Party shall pay the amount of such
liability to the Indemnitee on 

                                      71
<PAGE>
 
demand or, in the case of any notice in which the amount of the claim (or any
portion thereof) is estimated, on such later date when the amount of such claim
(or such portion thereof) becomes finally determined. If the Indemnifying Party
has timely disputed its liability with respect to such claim, as provided above,
the Indemnifying Party and the Indemnitee shall proceed in good faith to
negotiate a resolution of such dispute and, if not resolved through negotiations
by the 90th day after notice of such claim was given to the Indemnifying Party,
the Indemnifying Party and the Indemnitee will resolve such dispute in
accordance with Section 14.11.

without time limitation and shall not terminate at any time; provided, however,

that as to clauses (i) and (ii) above, such obligations to indemnify, defend and

which the Indemnitee shall have, before the expiration of the applicable period,
made a claim by delivering a notice (stating in reasonable detail the basis of
such claim) to the Indemnifying Party.

Hundred Fifty Thousand Dollars ($250,000) (the "Threshold"), in which event
Primestar and each of the Stockholders or Buyer, as the case may be, shall be
responsible for the full amount of such Damages, including the initial $250,000
of Damages which are subject to the Threshold.  Claims made pursuant to the
representations and warranties contained in or made pursuant to Sections 6.3,

breach by such Stockholder of its obligations hereunder to be performed prior to
such termination and (iii) any Third Party Claim.

captions herein and the table of contents hereto are for convenience of
reference only, do not constitute part of this Agreement and will not be deemed

hereto to dollars or "$" shall mean United States Dollars. Unless otherwise

<PAGE>
 
schedules are to schedules to this Agreement and all references herein to
exhibits are to exhibits to this Agreement.

          Section 14.9.  Entire Agreement. This Agreement constitutes the entire
                         ----------------                                       
agreement between the parties with respect to the subject matter hereof and this
Agreement supersedes all prior negotiations, agreements and understandings of
the parties of any nature, whether oral or written, relating thereto, other than
the Confidentiality Agreement.

          Section 14.10. Severability. If any provision of this Agreement or the
                         ------------                                           
application thereof to any Person or circumstance is determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof, or the application of such provision to Persons or
circumstances other than those as to which it has been held invalid or
unenforceable, shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby.  If the economic or legal substance
of the transactions contemplated hereby is affected in any manner adverse to any
party as a result thereof, the parties shall negotiate in good faith in an
effort to agree upon a suitable and equitable substitute provision to effect the
original intent of the parties. 

          Section 14.11. Dispute Resolution. Except as provided in Sections 4.2
                         ------------------                        -------------
and 4.3 and subject to Section 13.3, resolution of any and all disputes arising 
- -------                ------------     
from or in connection with this Agreement, whether based on contract, tort, or
otherwise (collectively, "Disputes"), shall be exclusively governed by and
settled in accordance with the provisions of this Section 14.11. The parties
                                                  -------------              
hereto shall use all commercially reasonable efforts to settle all Disputes
without resorting to mediation, arbitration or otherwise. If any Dispute remains
unsettled, a party hereto may commence proceedings hereunder by delivering a
written notice from a Senior Vice President or comparable executive officer of
such party (the "Demand") to the other parties providing reasonable description
of the Dispute to the others and expressly requesting mediation hereunder. The
parties hereby agree to submit all Disputes to non-binding mediation before a
mediator reasonably acceptable to all parties involved in such Dispute. If,
after such mediation, the parties subject to such mediation disagree regarding
the mediator's recommendation, such Dispute shall be submitted to arbitration
under the terms hereof, which arbitration shall be final, conclusive and binding
upon the parties, their successors and assigns. The arbitration shall be
conducted in Los Angeles, California by three arbitrators acting by majority
vote (the "Panel") selected by agreement of the parties not later than ten (10)
days after delivery of the Demand or, failing such agreement, appointed pursuant
to the

                                      79
<PAGE>
 
commercial arbitration rules of the American Arbitration Association, as amended
from time to time (the "AAA Rules"). The decision of the Panel shall be rendered
promptly but in no event more than 60 days after the conclusion of submission of
evidence. If an arbitrator so selected becomes unable to serve, his or her
successors shall be similarly selected or appointed. The arbitration shall be
conducted pursuant to the Federal Arbitration Act and such procedures as the
parties subject to such arbitration may agree, or, in the absence of or failing
such agreement, pursuant to the AAA Rules. Notwithstanding the foregoing: (i)
each party to a Dispute shall have the right to audit the books and records of
the other party to such dispute that are reasonably related to the Dispute; (ii)
each party to a Dispute shall provide to the other, reasonably in advance of any
hearing, copies of all documents which such party intends to present in such
hearing; and (iii) each party to a Dispute shall be allowed to conduct
reasonable discovery through written requests for information, document
requests, requests for stipulation of fact and depositions, the nature and
extent of which discovery shall be determined by the parties. The award shall be
in writing and shall specify the factual and legal basis for the award. The
Panel shall apportion all costs and expenses of arbitration, including the
Panel's fees and expenses and fees and expenses of experts, between the
prevailing and non-prevailing party as the Panel deems fair and reasonable.
Notwithstanding the foregoing, in no event may the Panel award consequential,
special, exemplary or punitive damages. Any arbitration award, including
injunctive relief, shall be binding and enforceable against the parties hereto
and judgment may be entered thereon in any court of competent jurisdiction.

          Section 14.12. Exhibits and Schedules; Disclosure.  All exhibits and
                         ----------------------------------                   
schedules attached hereto are hereby incorporated in and made a part of this
Agreement as if set forth in full herein.  Capitalized terms used in the
schedules hereto but not otherwise defined therein shall have the respective
meanings assigned to such terms in this Agreement.  Disclosure of any item in
any section of or on any schedule to this Agreement shall not constitute
disclosure of such item in any other section of or on any other schedule to this
Agreement, whether or not the existence of the item or its contents should be or
is relevant to any other section of or schedule to this Agreement, unless an
explicit cross-reference thereto appears in such other section or schedule.

          Section 14.13. Governing Law.  This Agreement will be governed by and
                         -------------                                         
construed in accordance with the internal laws of the State of New York
applicable to contracts made and to be performed entirely within such State,
without regard to the conflicts of law principles of such State.

          Section 14.14. Counterparts. This Agreement may be executed in 
                         ------------
separate counterparts, each such counterpart being deemed to be an original
instrument, and all such counterparts shall together constitute the same
agreement.

          Section 14.15. Interpretation. For the purposes of this Agreement, (i)
                         --------------                   
words in the singular shall be held to include the plural and vice versa and
                                                              ----------    
words of one gender shall be held to include the other gender as the context
requires, (ii) the terms "hereof", "herein", and "herewith" and words of similar
import shall, unless otherwise stated, be construed to refer to this Agreement
as a whole and not to any particular provision of this Agreement, (iii) the word
"including" and words of similar import when used in this Agreement shall mean
"including, without limitation", unless otherwise specified, and (iv) the word
"or" shall not be exclusive.

accommodation in excess of any Contractual obligation required under the terms
of such agreement) in all reasonable respects with Seller and Primestar to
obtain prior to the Closing all Consents and to resolve all impracticalities of
assignments or transfers necessary to sell, assign, convey, transfer and deliver
to Buyer or Newco (if Buyer so elects) the Transferred Assets.  If any such
Consent is not obtained or if an attempted assignment would be ineffective or
would impair Seller's, Primestar's, Buyer's or Newco's rights under any such
Contract, Lease or License so that Buyer or Newco (if Buyer so elects) would not
receive all such rights, then (1) each of Seller and Primestar will (x) ensure
that the full benefits of any such Contract, Lease or License are provided or
caused to be provided to Buyer or Newco (if Buyer so elects), and (y) pay
promptly or cause to be paid promptly to Buyer or Newco (if Buyer so elects)
when received all monies and other properties received by Seller, any Seller
Specified Affiliates or any other Affiliate of Seller on its behalf with respect
to a Contract, Lease or License to the extent that Buyer (or Newco) would have
been entitled to receive such monies and other properties if such Consent had
been obtained; and (2) in consideration of Seller and Primestar providing or
causing to be provided to Buyer or Newco (if Buyer so elects) the full benefits

                                      16

thereof, Buyer or Newco will perform and discharge on behalf of Seller and
Primestar all of Seller's and Primestar's liabilities, obligations or
commitments thereunder which are Assumed Liabilities described in Section 2.3 in
                                                                  -----------   
accordance with the provisions thereof.  In addition, Seller and Primestar will
take such other actions (at Seller's and Primestar's expense) as may reasonably
be requested by Buyer in order to place Buyer or Newco (if Buyer so elects),
insofar as reasonably possible, in the same position as if such Contract, Lease
or License had been transferred as contemplated hereby and so that all the
benefits relating thereto, including possession, use, potential for gain and
dominion, control and command, shall inure to Buyer or Newco (if Buyer so
elects), subject to the assumption by Buyer of all obligations and risks that
arise after the Closing Date with respect to such Contract, Lease or License
including all risks of loss thereunder.  Notwithstanding the foregoing, if any
such Consent is not obtained prior to the Closing, Seller will continue to use
its commercially reasonable efforts (at Seller's expense) to obtain all such
Consents (and, if and when such Consents are obtained, the transfer of the
applicable Contract, Lease or License will be effected in accordance with the
terms of this Agreement).

that, with respect to the preceding clause (i), such assumption shall not

of Buyer will assume or undertake to pay, perform or discharge and none thereof
will be liable for, and Seller will remain liable for and pay, perform and
discharge when due, all Liabilities of Seller arising under the Ground Satellite
Assets other than the Ground Satellite Liabilities.

          (b) Assumption of In-Orbit Liabilities.  Subject to Section 2.3(c),
              ----------------------------------              -------------- 
effective as of the Subsequent Closing, and upon the terms and subject to the
conditions of this Agreement, Buyer agrees to assume (i) all Liabilities of
Seller arising from and after the Subsequent Closing Date under or in respect of
the In-Orbit Satellite Assets and (ii) that portion of the Reimbursement
Obligation attributable to the construction of the In-Orbit Satellite; provided,

that in the case of the preceding clause (i) such assumption shall not include
assumption of any Liabilities (x) which relate to any In-Orbit Satellite
Contract as to which Seller is in default under such obligations at the
Subsequent Closing Date (or would be in default at the Subsequent Closing Date,
assuming the giving of any applicable notices and the lapse of any applicable
waiting periods under the In-Orbit Satellite Contracts), provided further that
the portion of any Liabilities under the In-Orbit Satellite Contracts as to
which Seller is not in default shall not be excluded hereby or (y) which are due
and payable on or before the Subsequent Closing Date.  In addition (but without
duplication), Buyer agrees to assume, effective as of the Subsequent Closing
Date, the payment of $8 million which may be due under the Loral Contract with
respect to the in-orbit acceptance of the In-Orbit Satellite and Liabilities not
to exceed $17 million with respect to disputes with Loral regarding the
insurance required by the terms of the Loral Contract and the tracking,
telemetry and control provided by Loral with respect to the In-Orbit Satellite,
in each case in accordance with the terms of the Loral Contract.  The
Liabilities required to be assumed by Buyer pursuant to this Section 2.3(b) are
                                                             --------------

Retained Liabilities (as defined below) include all Liabilities of Seller and
Primestar arising under the Transferred Assets that accrued, occurred or existed
on or prior to the Initial Closing Date, in the case of the Ground Satellite

election, all Tax returns and reports filed by Buyer, Seller and Primestar shall
be prepared consistently with such allocation.  If Seller or, when applicable,
Primestar, shall have withheld its consent to such allocation (which consent
shall not be unreasonably withheld) and Buyer and Seller have acted in good
faith to resolve the differences with respect to the items on the Asset
Acquisition Statement or any Revised Statement for a period of 20 days after
Buyer's or Primestar's receipt of notice of objections or suggested changes from
Seller, and, within such 20-day period, Buyer and Seller (or, when applicable,
Primestar) are unable to resolve such differences which, in the aggregate, are

in such statements and (ii) Buyer, Seller and Primestar shall refer any issues
as to which such differences exist to an independent accounting firm mutually
acceptable to Buyer, Seller and Primestar for resolution, which shall resolve
such issues within 30 days of the date submitted and whose resolution shall be
final and binding on the parties hereto. The fees and expenses of such

required notices to third parties, and shall use its commercially reasonable
efforts to obtain all required Consents, including all Consents required by
counterparties to the Ground Satellite Contracts and the In-Orbit Satellite
Contracts, all required Consents of Governmental Entities and bondholders or
lenders of Seller or any of its Affiliates, and any other material third-party
Consents that may be required or that Buyer reasonably may request, in
connection with the transactions contemplated by this Agreement.  Within five
Business Days following the date of this Agreement (but in no event prior to
approval of the Board of Directors of GM) Buyer and Seller hereto shall file any
Notification and Report Forms and related materials that it may be required to
file with the Federal Trade Commission ("FTC") and the Antitrust Division of the
United States Department of Justice (the "Antitrust Division") under the HSR
Act, and shall make any further filings pursuant thereto that may be necessary,
proper or advisable.  Within five calendar days following the date of this
Agreement, Buyer and Seller shall make all notifications and file all
applications and related materials that it may be required to file with the FCC
or any other Governmental Entity having authority with respect to Licenses for
the use of orbital slots or the provision of communications services or other
communications Licenses in connection with the transactions contemplated hereby,
and, subject to Section 8.4 below, shall use commercially reasonable efforts to

obtain at the earliest practicable date all necessary Consents, including a
Final Order, for assignment of the FCC License.  At the time that the parties
file an application with the FCC to obtain the FCC Consent and Final Order,
Primestar and TSAT shall submit a letter request to the FCC to withdraw any
pending request to transfer control of the FCC License, which request may be
made contingent upon giving of the FCC Consent.  As promptly as is practicable
after the date of this Agreement, each of Buyer and Seller shall take any
additional action (including the implementation of an Acceptable Alternative
Arrangement (to the extent subject to action by the FCC) and submit any
additional filings, submissions or applications required by the FCC, the FTC and
the Antitrust Division, that may be necessary, proper or advisable to effect to
the fullest extent feasible the consummation of the transactions contemplated by
this Agreement) in connection with any other Consents of, to or with any
Governmental Entities and third parties that it may be required to give, make or
obtain and shall

refrain from taking any action the purpose or effect of which could reasonably
be expected to make it less likely that such Consents will be given, made or
obtained on the terms provided for in this Agreement. Without limiting the
generality of the foregoing, each of Buyer and Seller shall: (i) cooperate in
all respects with each other in connection with any filing, submission,
adversarial proceeding or the timing thereof; (ii) in connection with any
investigation or other inquiry, including any proceeding initiated by a private
party, keep the other parties hereto informed on a timely basis of any material
communication received by such party from, or given by such party to, the FTC,
the Antitrust Division, the FCC or any other Governmental Entity and of any
material communication received or given in connection with any Action by a
private party, in each case regarding any of the transactions contemplated by
this Agreement, and permit any other party hereto to preview any material
communication given by or to it; and (iii) consult with each other, in advance
of any meeting or conference with such Governmental Entities or, in connection
with any Action by a private party. Each of Buyer and Seller will use its
commercially reasonable efforts to obtain such approvals as promptly as possible
and, in this regard, provide all information reasonably requested, assist and
cooperate with one another to make the necessary filings and take such steps as
may be necessary to secure the non-objection of the relevant antitrust and
regulatory authorities, including a Final Order for assignment of the FCC
License.

of the assignment of the FCC License to Buyer or Newco.  Each of Buyer, Seller,
Primestar and PLP shall take all commercially reasonable steps necessary, and
shall supply to the other such parties and/or to the FCC all information
reasonably necessary, to obtain such Final Order, and shall use its commercially
reasonable efforts, including the implementation of an Acceptable Alternative
Arrangement, to effect to the fullest extent feasible the consummation of the
transactions contemplated in this Agreement.  The parties shall also cooperate
with respect to any required submission to the FCC and/or the International
Telecommunication Union, including any submission required to allow use of the
101 and 119 West Longitude orbital locations in conjunction with a single
consumer satellite receive antenna.  Notwithstanding the foregoing, nothing
contained in this Agreement shall create any obligation on the part of Buyer to
accept (as a condition to receipt of such Final Order or otherwise):  (i) any
restriction on the right of Buyer to operate pursuant to the FCC License held by
Buyer with

                                      45

respect to frequencies at any orbital location, including the right to use all
assigned frequencies authorized thereunder to provide high-powered DBS services,
other than any such restrictions generally imposed on operators of high powered
DBS services by applicable Regulatory Provisions, and restrictions of the types
generally and customarily imposed by the FCC on operators of high powered DBS
services, and such other restrictions, which, individually, or in the aggregate,
do not have a Transferred Asset Material Adverse Effect or a Buyer Material
Adverse Effect; (ii) any change in the management or ownership (other than as
contemplated hereunder) of Buyer, or in any voting or other rights of any
shareholder of Buyer or its Affiliates; or (iii) a requirement that Buyer
dispose of all or any part of the frequencies at any orbital location
owned by Buyer, (each of the conditions contained in the foregoing Sections

                                                           ---------------      
of the parties hereto agrees that if the FCC Consent has not been obtained on or
before September 30, 1999, each party will use its commercially reasonable
efforts to negotiate and enter into a mutually acceptable Acceptable Alternative
Arrangement prior to December 31, 1999. If an Acceptable Alternative Arrangement
is not entered into on or before December 31, 1999, either party may terminate
this Agreement on or after such date. If an Acceptable Alternative Arrangement
is entered into on or prior to December 31, 1999, each of the parties hereto
shall continue to use their commercially reasonable efforts to obtain the FCC
Consent.

          If an Acceptable Alternative Arrangement is entered into, upon receipt
of the FCC Consent, Seller shall immediately assign the FCC License to Buyer or
Newco and such Acceptable Alternative Arrangement shall be cancelled
concurrently with such transfer. Thereafter, at the closing of the transactions
contemplated hereby and thereby, the Purchase Price will be paid by Buyer to
Seller, after giving effect to any reductions in the amount thereof for all
payments made to Seller under such Acceptable Alternative Arrangement.

          If an Acceptable Alternative Arrangement is entered into on or prior
to the termination hereof, the provisions of this Agreement shall continue to be
in full force and effect, subject to any modifications of the terms hereof in
connection with the Acceptable Alternative Arrangement, including a date certain
upon which the Acceptable Alternative Arrangement shall terminate upon which
this Agreement may be terminated by either party.

          Notwithstanding the foregoing, Seller shall continue to perform all of
its material obligations under the FCC License until the earlier of the
Subsequent Closing Date or the date of termination of this Agreement, and shall
use commercially reasonable efforts to continue to remain in "due diligence" in
accordance with the construction and operation of the DBS system (as the term is
used in the FCC's rules and as defined in this Regulatory Provisions), and to
hold a valid authorization for its DBS system, until the earlier of the
Subsequent Closing Date or the date of termination of this Agreement.

through the Subsequent Closing Date, each of Seller and Primestar shall afford
to Buyer and its representatives free and full access at all reasonable times to
the properties, personnel, books and records relating to the Transferred Assets
and the Assumed Liabilities (such access not to unreasonably interfere with the
business of Seller or Primestar) in order that the Buyer and its representatives

desire to make of all matters relating to the transactions contemplated
hereunder.  Any proprietary information provided pursuant to this Section 8.6

diminish in any respect any of the representations or warranties of Seller or
Primestar or Buyer's rights in respect of

injunctive relief or such other remedy as may be available at law or in equity
for any breach by another party of this Section.

other in a timely fashion such Tax data, prior Tax returns and filings and other

Primestar or Seller of any Tax returns, elections, consents or certificates

such Tax return, audit or examination, proceeding or determination, and will

examination, proceeding or determination that affects any amount required to be
shown on any Tax return of the other party for any period.  Without limiting the
generality of the foregoing, each of Buyer, Primestar and Seller will retain
copies of all Tax returns, supporting work schedules and other records relating
to Tax periods or portions thereof ending prior to or on the Closing Date.  To
the extent that Buyer incurs additional out-of-pocket expenses in order to
deliver Tax return information to Seller or Primestar, Seller or Primestar shall
reimburse Buyer for the amount of all additional expenses.

first commenced until the Subsequent Closing Date to the extent that the terms
and conditions of any such Claims Made Policies so allow, provided that all of
Seller's or Primestar's reasonable costs and expenses incurred in connection
with the foregoing are advanced by Buyer. All recoveries in respect of such
claims shall be for the account of Buyer.  In addition, Buyer may purchase (at
Buyer's expense), prior to, on or after the Subsequent  Closing Date, discovery
coverage with respect to Claims Made Policies to provide coverage with respect
to such Claims Made Policies for claims submitted by Buyer after the Subsequent
Closing Date with respect to incidents occurring prior to the Subsequent Closing
Date, and all recoveries under such discovery coverage will be for the account
of Buyer.

such action, Seller and Primestar will pay to Buyer their respective equitable
share (based on the amount of premiums paid by or allocated to the Transferred
Assets in respect of the applicable policy) of any proceeds received by Buyer as
a result of such action (after deducting Seller's and Primestar's reasonable
costs and expenses incurred in connection with such action).

and against, and pay or reimburse, as the case may be, the Buyer Group for, any
and all Damages, as incurred, suffered by Buyer or any other member of the Buyer

          (b) any breach or violation of any covenant or agreement of Seller,
Primestar, PLP or the Stockholders contained herein or in any certificate or
other document delivered pursuant hereto;

          (c)  any Retained Liability;

          (d) the enforcement by the Buyer Group of their rights to be

          Section 13.2 Indemnification by Buyer.  Subject to the other
                       ------------------------                       
provisions of this Article XIII, Buyer shall indemnify, defend and hold harmless
Seller and its Subsidiaries and Affiliates and their respective employees,
directors, officers, stockholders, representatives and agents (collectively, the

way relating to or in respect of:

          (d) the enforcement by the Seller Group of their rights to be

           Section 13.3 Procedures for Indemnification.
                        ------------------------------ 

          (a) If a claim or demand is made against an Indemnitee, or an
Indemnitee shall otherwise learn of an assertion, by any Person who is not a
party to this Agreement (or an Affiliate thereof) (a "Third Party Claim") as to
which one or more parties (collectively, the "Indemnifying Party") may be
obligated to provide indemnification pursuant to this Agreement, such Indemnitee
will notify the Indemnifying Party in writing, and in reasonable detail, of the
Third Party Claim reasonably promptly after becoming aware of such Third Party
Claim; provided, however, that failure to give such notification will not affect
       --------  -------                                                        
the indemnification provided hereunder except to the extent the Indemnifying
Party shall have been actually prejudiced as a result of such failure.

          (b) If a Third Party Claim is made against an Indemnitee and the
Indemnifying Party unconditionally and irrevocably acknowledges in writing its
obligation to indemnify the Indemnitee therefor (subject to verification that
any losses or costs in respect thereof constitute Damages and compliance with
the other terms hereof), the Indemnifying Party will be entitled to assume the
defense thereof (at the expense of the Indemnifying Party) with counsel selected
by the Indemnifying Party and reasonably satisfactory to the Indemnitee.  Should
the Indemnifying Party so elect to assume the defense of a Third Party Claim,
the Indemnifying Party will not be liable to the

                                      62
<PAGE>
 
Indemnitee for any legal or other expenses subsequently incurred by the
Indemnitee in connection with the defense thereof; provided that, if in any
Indemnitee's reasonable judgment a conflict of interest exists in respect of
such claim, such Indemnitee shall have the right to employ separate counsel
(which shall be reasonably satisfactory to the Indemnifying Party) and one local
counsel to represent such Indemnitee and in that event the reasonable fees and
expenses of each such counsel shall be paid by such Indemnifying Party. If the
Indemnifying Party assumes the defense of any Third Party Claim, the Indemnitee
shall have the right to participate in the defense thereof and to employ
counsel, at its own expense (except as otherwise provided in the preceding
sentence), separate from the counsel employed by the Indemnifying Party. The
Indemnifying Party shall be liable for the fees and expenses of counsel employed
by the Indemnitee for any period during which the Indemnifying Party has failed
to assume the defense thereof or if it does not expressly elect to assume the
defense thereof (including acknowledging its indemnification obligation as
aforesaid). If the Indemnifying Party assumes the defense of any Third Party
Claim, the Indemnifying Party will promptly supply to the Indemnitee copies of
all correspondence and documents relating to or in connection with such Third
Party Claim and keep the Indemnitee fully informed of all developments relating
to or in connection with such Third Party Claim (including providing to the
Indemnitee on request updates and summaries as to the status thereof). If the
Indemnifying Party chooses to defend a Third Party Claim, all the Indemnitees
shall reasonably cooperate with the Indemnifying Party in the defense thereof
(such cooperation to be at the expense, including reasonable legal fees and
expenses, of the Indemnifying Party).

          (c) If the Indemnifying Party unconditionally and irrevocably
acknowledges in writing its obligation to indemnify the Indemnitee for a Third
Party Claim (subject to verification that any losses or costs in respect thereof
constitute Damages and compliance with the other terms hereof), the Indemnitee
will agree to any settlement, compromise or discharge of such Third Party Claim
which the Indemnifying Party may recommend and which by its terms obligates the
Indemnifying Party to pay the full amount of Damages in connection with such
Third Party Claim and unconditionally and irrevocably releases the Indemnitee
(and the other members of the Buyer Group or the Seller Group, as the case may
be) completely from all Liability in connection with such Third Party Claim,
provided, however, that, without the Indemnitee's prior written consent, the
- --------  -------                                                           
Indemnifying Party shall not consent to any settlement, compromise or discharge
(including


                                      63
<PAGE>
 
the consent to entry of any judgment), and the Indemnitee may refuse to agree to
any such settlement, compromise or discharge that, in the reasonable opinion of
the Indemnitee could reasonably be expected to materially and adversely affect
the Indemnitee. If the Indemnifying Party unconditionally and irrevocably
acknowledges in writing its obligation to indemnify the Indemnitee for a Third
Party Claim, the Indemnitee shall not (unless required by law) admit any
liability with respect to, or settle, compromise or discharge, such Third Party
Claim without the Indemnifying Party's prior written consent (which consent
shall not be unreasonably withheld).

          (d) Any claim on account of Damages which does not involve a Third
Party Claim shall be asserted by reasonably prompt written notice given by the
Indemnitee to the Indemnifying Party from whom such indemnification is sought.
The failure by any Indemnitee so to notify the Indemnifying Party shall not
relieve the Indemnifying Party from any liability which it may have to such
Indemnitee under this Agreement, except to the extent that the Indemnifying
Party shall have been actually prejudiced by such failure.  If the Indemnifying
Party does not dispute its liability to the Indemnitee with respect to the claim
made in such notice by notice to the Indemnitee prior to the expiration of a 30-
calendar-day period following the Indemnifying Party's receipt of notice of such
claim, the claim shall be conclusively deemed a liability of the Indemnifying
Party under this Agreement.  The Indemnifying Party shall pay the amount of such
liability to the Indemnitee on demand or, in the case of any notice in which the
amount of the claim (or any portion thereof) is estimated, on such later date
when the amount of such claim (or such portion thereof) becomes finally
determined.  If the Indemnifying Party has timely disputed its liability with
respect to such claim, as provided above, the Indemnifying Party and the
Indemnitee shall proceed in good faith to negotiate a resolution of such dispute
and, if not resolved through negotiations by the 90th day after notice of such
claim was given to the Indemnifying Party, the Indemnifying Party and the
Indemnitee will resolve such dispute in accordance with Section 14.11.

(d) and (e), and Sections 13.2(c) and (d) shall continue without time limitation

                                     --------  -------
and (ii) above, such obligations to indemnify, defend and hold harmless shall
not terminate with respect to any individual item as to which the Indemnitee
shall have, before the expiration of the applicable period, made a claim by
delivering a notice (stating in reasonable detail the basis of such claim) to
the Indemnifying Party.

          Section 13.5 Certain Limitations.
                       ------------------- 

          (a) No monetary amount shall be payable by Seller or Buyer to any

                                          ---------------    ---------------    
the case may be (other than with respect to the representations and warranties

aggregate amount of Damages actually incurred by the Buyer Group or the Seller
Group, as the case may be, with respect to all claims shall exceed on a
cumulative basis Two Hundred Fifty Thousand Dollars ($250,000) (the
"Threshold"), in which event Primestar and each of the Stockholders or Buyer, as
the case may be, shall be responsible for the full amount of such Damages,
including the initial $250,000 of Damages which are subject to the Threshold.
Claims made pursuant to the representations and warranties contained in or made
pursuant to Sections 5.2, 5.4, 5.6, 5.10(i), 5.11, 5.12, 5.16, and 7.6 will not

be, shall have any right to obtain an indemnification payment under this
Agreement to the extent amounts received by the members of such group as
indemnification payments hereunder equal or exceed the Purchase Price; provided,

whole or in part, to any direct or indirect Subsidiary. Any conveyance,
assignment or transfer requiring the prior written consent of the other parties
hereto which is made without such consent shall be void ab initio.  No

either Buyer or Seller in exercising any right, power or privilege hereunder
will operate as a waiver thereof, nor will any waiver on the part of either
Buyer or Seller of any right, power or privilege hereunder operate as a waiver
of any other right, power or privilege hereunder, nor will any single or partial
exercise of any right, power or privilege hereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege
hereunder.  The rights and remedies herein provided are cumulative and, except
as otherwise provided in Section 13.5(c), are not exclusive of any rights or
                         ---------------

                       -----------------------                       
warranties, covenants and agreements made by Seller in this Agreement or in any

          Section 14.9  Entire Agreement.  This Agreement constitutes the entire
                        ----------------                                        
agreement between the parties with respect to the subject matter hereof and this
Agreement supersedes all prior negotiations, agreements and understandings of
the parties of any nature, whether oral or written, relating thereto, other than
the Confidentiality Agreement.

          Section 14.10 Severability.  If any provision of this Agreement or the
                        ------------                                            
application thereof to any Person or circumstance is determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof, or the application of such provision to Persons or
circumstances other than those as to which it has been held invalid or
unenforceable, shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby. If the economic or legal substance of
the transactions contemplated hereby is affected in any manner adverse to any
party as a result thereof, the parties shall negotiate in good faith in an
effort to agree upon a suitable and equitable substitute provision to effect the

          Section 14.11 Dispute Resolution. Except as provided in Section 3.2(b)
                        ------------------                        --------------
and subject to Section 13.3, resolution of any and all disputes arising from or
               ------------                                                    
in connection with this Agree  ment, whether based on contract, tort, or
otherwise (collectively, "Disputes"), shall be exclusively governed by and
settled in accordance with the provisions of this Section 14.11. The parties
                                                  -------------             
hereto shall use all commercially reasonable efforts to settle all Disputes
without resorting to mediation, arbitration or otherwise.  If any Dispute
remains unsettled, a party hereto may commence proceedings hereunder by
delivering a written notice from a Senior Vice President or comparable executive
officer of such party (the "Demand") to the other parties providing reasonable
description of the Dispute to the others and expressly requesting mediation
hereunder.  The parties hereby agree to submit all Disputes to non-binding
mediation before a mediator reasonably acceptable to all parties involved in
such Dispute.  If, after such mediation, the parties subject to such mediation
disagree regarding the mediator's

                                      71
<PAGE>
 
recommendation, such Dispute shall be submitted to arbitration under the terms
hereof, which arbitration shall be final, conclusive and binding upon the
parties, their successors and assigns. The arbitration shall be conducted in Los
Angeles, California by three arbitrators acting by majority vote (the "Panel")
selected by agreement of the parties not later than ten (10) days after delivery
of the Demand or, failing such agreement, appointed pursuant to the commercial
arbitration rules of the American Arbitration Association, as amended from time
to time (the "AAA Rules"). The decision of the Panel shall be rendered promptly
but in no event more than 60 days after the conclusion of submission of
evidence. If an arbitrator so selected becomes unable to serve, his or her
successors shall be similarly selected or appointed. The arbitration shall be
conducted pursuant to the Federal Arbitration Act and such procedures as the
parties subject to such arbitration may agree, or, in the absence of or failing
such agreement, pursuant to the AAA Rules. Notwithstanding the foregoing: (i)
each party to a Dispute shall have the right to audit the books and records of
the other party to such dispute that are reasonably related to the Dispute; (ii)
each party to a Dispute shall provide to the other, reasonably in advance of any
hearing, copies of all documents which such party intends to present in such
hearing; and (iii) each party to a Dispute shall be allowed to conduct
reasonable discovery through written requests for information, document
requests, requests for stipulation of fact and depositions, the nature and
extent of which discovery shall be determined by the parties. The award shall be
in writing and shall specify the factual and legal basis for the award. The
Panel shall apportion all costs and expenses of arbitration, including the
Panel's fees and expenses and fees and expenses of experts, between the
prevailing and non-prevailing party as the Panel deems fair and reasonable.
Notwithstanding the foregoing, in no event may the Panel award consequential,
special, exemplary or punitive damages. Any arbitration award, including
injunctive relief, shall be binding and enforceable against the parties hereto
and judgment may be entered thereon in any court of competent jurisdiction.

          Section 14.12 Exhibits and Schedules; Disclosure. All exhibits and
                        ----------------------------------                  
schedules attached hereto are hereby incorporated in and made a part of this
Agreement as if set forth in full herein.  Capitalized terms used in the
schedules hereto but not otherwise defined therein shall have the respective

any section of or on any schedule to this Agreement shall not constitute
disclosure of such item in any other section

                                      72

of or on any other schedule to this Agreement, whether or not the existence of
the item or its contents should be or is relevant to any other section of or
schedule to this Agreement, unless an explicit cross-reference thereto appears
in such other section or schedule.

          Section 14.13 Governing Law. This Agreement will be governed by and
                        -------------                                         
construed in accordance with the internal laws of the State of New York
applicable to contracts made and to be performed entirely within such State,
without regard to the conflicts of law principles of such State.

          Section 14.14 Counterparts. This Agreement may be executed in separate
                        ------------   
counterparts, each such counterpart being deemed to be an original instrument,
and all such counterparts shall together constitute the same agreement.

          Section 14.15 Interpretation.  For the purposes of this Agreement, (i)
                        --------------                                          
words in the singular shall be held to include the plural and vice versa and
                                                              ----------    
words of one gender shall be held to include the other gender as the context
requires, (ii) the terms "hereof", "herein", and "herewith" and words of similar
import shall, unless otherwise stated, be construed to refer to this Agreement
as a whole and not to any particular provision of this Agreement, (iii) the word
"including" and words of similar import when used in this Agreement shall mean
"including, without limitation", unless otherwise specified, and (iv) the word
"or" shall not be exclusive.
