Newco are able to reach an agreement with respect to the terms of a New
PRIMESTAR Agreement, as soon as practicable following the execution and delivery
of such agreement, the Company shall be dissolved and liquidated and the shares
of Newco capital stock received in the Transaction will be distributed 14.26% to
PRIMESTAR (representing 4.99% of Newco's outstanding equity ownership at the
closing) (free and clear of all claims, liens, security interests and other
encumbrances) and 85.74% to LNET, respectively.
     
     5.   REPRESENTATIONS.    Each of the parties, severally and not jointly,

of competent jurisdiction to be invalid, illegal or unenforceable, such
provision shall be severed from this Agreement, and in either case the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby.
     
     9.   COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, and each such executed counterpart will be an original instrument.
     
     10.  SUCCESSORS AND ASSIGNS.  This Agreement shall bind and inure to the

                                                                      EXHIBIT A
                                          
                   ASSIGNMENT, ASSUMPTION AND AMENDMENT AGREEMENT

     1.   For good and valuable consideration, receipt of which is hereby
acknowledged, ResNet Communications, LLC, a Delaware limited liability company
("Assignor"), does hereby sell, assign, transfer and set over as of the Closing
Date (as defined below) to GLOBAL INTERACTIVE COMMUNICATIONS CORPORATION, a
Delaware corporation ("Assignee"), all of Assignor's right, title and interest
in and to that certain Signal Availability Agreement (the "Signal Availability
Agreement"), dated as of June 4, 1997, between Assignor and PRIMESTAR MDU, Inc.
("PRIMESTAR"), as successor in interest to TCI Satellite MDU, Inc.; and Assignee
hereby assumes the obligations of Assignor under, and agrees to be bound by the
terms and conditions of, the Signal Availability Agreement as modified by
Paragraph 3 below.

     2.   This assignment is made pursuant to a Consent and Restructuring
Agreement, dated as of November _6_, 1998, among Assignor, PRIMESTAR and the
parties named therein, and is entered into in connection with a transaction
pursuant to which Assignor and certain other parties will each contribute to
Assignee substantially all of the assets of each such company, subject to
certain specified liabilities, in exchange for capital stock in the parent
corporation of Assignee (collectively, the "Transaction;" the date of the
consummation of the Transaction being the "Closing Date").

     3.   The terms of the Signal Availability Agreement shall hereby be amended
such that:

     (a)  The Signal Availability Agreement shall be deemed to apply only to
Assignor's headend installations at the sites set forth on SCHEDULE I hereto
(all of which sites are subject to video services agreements of the Assignor
existing on the Closing Date and contributed to Assignee in connection with the
Transaction);

     (b)  As a condition to such assignment Assignee shall be prohibited from
offering digital overlays or digital tiers of any direct broadcast satellite
("DBS") provider other than PRIMESTAR, Inc. to any multi-family dwelling unit
property covered by the Signal Availability Agreement; and

     (c)  Section 11(d) of the Signal Availability Agreement shall be deemed
modified and restated as follows (except that the last unnumbered paragraph
thereof beginning with the words "Subject to the provisions of Section 17" shall
remain unmodified):
          
          "(d)   If for any reason other than an event of Force
          Majeure, Satellite is unable to provide the signal of the
          Programming Services, this Agreement shall terminate upon 90
          days prior written notice from Satellite to ResNet.  If this
          Agreement is terminated pursuant to this Section 11(d),
          ResNet shall use its best efforts to enter into an agreement
          to receive the signal of the Programming Services at the
          Headends from a signal provider (a "Compatible Signal
          Provider") that provides digital signals in a format
          compatible with the Equipment. If this Agreement is
          terminated pursuant to this Section 11(d) prior to December
          31, 2003 and ResNet is not able to enter into an agreement
          with a Compatible Signal Provider, Satellite will pay to
          ResNet an amount equal to the price paid by ResNet for
          purchasing equipment that is compatible with the signals
          provided by the new signal provider (the "Incompatible
          Signal Provider") for all Headends included under this
          Agreement as of the date of termination, less the fair
          market value of the Equipment that is replaced, up to $200
          per IRD for a maximum of 4,000 IRDs.  Satellite shall have
          no liability to ResNet with respect to any increase in the
          transport fees payable by ResNet to the Incompatible Signal
          Provider over the amount of the Availability Fees payable by
          ResNet hereunder." 

     (d)  Section 3 of the Signal Availability Agreement shall be amended to add
the following provision:

          "Satellite will sell to ResNet the integrated receiver-decoders
          ("IRDs") (limited to no more than 4,000 IRDs), low-noise block
          converters and other equipment specified on EXHIBIT A hereto (the
          "Equipment").  The price payable by ResNet for the Equipment
          shall equal Satellite's actual cost therefor.  Payments will be
          made by ResNet in cash within 30 days after shipment by Satellite
          (which shipment shall be at Satellite's expense, but at ResNet's
          risk of loss) and receipt of Satellite's invoice specifying the
          purchase price and applicable sales taxes.  Late payments shall
          bear interest at the rate of 1.5% per month (or the highest
          amount permitted by law, if lower).  The Equipment sold by
          Satellite may be new from the manufacturer or may be previously
          authorized.  Equipment consisting of previously authorized IRDs
          will be reconditioned in accordance with the 

                                      4
<PAGE>

          standards set forth on EXHIBIT B hereto.  For a period of 12 months 
          from the date of delivery, Satellite or its authorized service 
          representatives will repair or replace (at its option) the Equipment 
          free of charge in the event of a defect in materials or workmanship. 
          ResNet shall bear the cost of shipment to the repair location
          designated by Satellite and Satellite shall bear the cost of shipment
          of replacement/repaired Equipment to the designated ResNet location.  
          The foregoing warranty does not apply to any appearance items of the 
          Equipment that do not adversely affect the performance of the 
          Equipment.  The warranty will not apply if the Equipment is damaged 
          as a result of (i) improper modification, alteration, maintenance, 
          repair, connection or disconnection of the Equipment by anyone other 
          than Satellite's authorized service representatives; (ii) improper 
          use of the Equipment; (iii) conditions outside the control of 
          Satellite; or (iv) accident, abuse or neglect.  SATELLITE SHALL NOT 
          BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES RESULTING FROM THE 
          USE OF THE EQUIPMENT OR ARISING OUT OF ANY BREACH OF THIS WARRANTY. 
          SATELLITE EXCLUDES AND DISCLAIMS ANY AND ALL OTHER EXPRESS OR IMPLIED 
          WARRANTIES, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS 
          FOR A PARTICULAR PURPOSE."

          IN WITNESS WHEREOF, the Assignor, Assignee and PRIMESTAR have caused
this Agreement to be signed as of the Closing Date.
