          The assets, properties and rights of each Seller to be sold, assigned,
conveyed, transferred and delivered to Buyer pursuant to this Agreement are
herein collectively referred to as the "Transferred Assets."  The term
"Transferred Assets" will include all additions and replacements to any of the
items described in this Section 2.1(a) from the date of this Agreement through
                        --------------                                        
the Closing Date, and will exclude, to the extent permitted by this Agreement,
all deletions, sales or other disposals of any of the foregoing from the date of
this Agreement through the Closing Date.

          (b)  Anything contained herein to the contrary notwithstanding, the
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

 
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.

Business Days prior to the Closing Date, Sellers shall deliver to Buyer a

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

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

 
(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.

                       --------------------                                
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

 
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

 
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

 
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.


                                      56

 
          (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.

                                      57

 
          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

 
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.

          Section 9.15. Transfer Restrictions.  (a)  The transfer agent of
                        ---------------------                             
Buyer's parent is authorized to place stop transfer instructions on its stock
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

 
          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

 
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.

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

 
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

 
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.

that as to clauses (i) 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.

indemnification of any claims pursuant to Section 13.1(a) or Section 13.2(a), as
                                          ---------------    ---------------

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,
                                                                -------------

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 $500,000,000; provided, that the limitation
                                                 --------                     
on Damages set forth in this Section 13.5(b) shall in no way affect the amount
                             ---------------

Liabilities retained by Seller.

          (c)  Anything contained herein to the contrary notwithstanding, and

be the sole and exclusive remedy of Buyer and the Buyer Group against the
Stockholders with respect to the matters described in Sections 13.1(a) through

          In addition, if the transactions contemplated hereby are terminated
prior to the Closing Date in accordance with the terms hereof, and without
limiting any rights against Primestar, MDU and PLP, the Buyer Group will not
have the right to seek indemnification from a Stockholder except with respect to
(i) any breach by Sellers of their obligation under Section 11.2, (ii) any
breach by such Stockholder of its obligations hereunder to be performed prior to
such termination and (iii) any Third Party Claim.

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
remedies which the parties may otherwise have at law or in equity.

warranties, covenants and agreements made by Seller in this Agreement or in any
certificates, statements or other documents delivered pursuant to this Agreement
shall be unaffected by any investigation made by or on behalf of Buyer or
Knowledge obtained as a result thereof or otherwise.

          Section 14.6. Fees and Expenses.  Each of Buyer, on the one hand, and

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

 
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.

                                      80

 
          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.
