           (a) June 30, 1998; or

           (b) The termination or cancellation of this Agreement as provided in
Article X of this Agreement.

                                  ARTICLE IV

                     MONTHLY CHARGE AND METHOD OF PAYMENT
                     ------------------------------------

     4.01  Monthly Charge.  Customer shall pay to Microspace monthly, in
           --------------                                               
advance, the sum of [**].

           If the term should not commence on the first day of a month or end on
the last day of a month, the monthly charge for the fractional part of the month
shall be calculated at a daily rate of one-thirtieth of the monthly charge
specified in the above paragraph.

           All payments shall be made to Microspace at its address as designated
in Paragraph 13.08 and shall be deemed to be made upon receipt thereof by
Microspace.  Microspace shall assess a late payment charge of one and one-half

                                   ARTICLE V

                INTERRUPTION OF TRANSMISSIONS OVER TRANSPONDERS
                -----------------------------------------------

     5.01  Outage Allowance.  If applicable, Microspace shall grant Customer an
           ----------------                                                    
Outage Allowance, as follows:

           If an "Outage Allowance Failure Period" (as defined below) occurs,
then for each full hour of such Outage Allowance Failure Period Microspace shall
grant Customer a pro rata Outage Allowance based upon the monthly charge for
Customer's Transponder Capacity and the length of the Outage Allowance Failure
Period, calculated pursuant to 

                                                                          Page 4

 
the equation below. Any such Outage Allowance shall be applied to the next
succeeding monthly billing to Customer and shall not in any case exceed one
month's standard billing. As used herein, "Outage Allowance Failure Period"
shall mean the aggregate period (in hours) -- only where such aggregation
exceeds twelve (12) hours during any consecutive thirty (30) day period --
during which a Transponder Capacity Failure(s) occurs. For purposes of this
Agreement, A Transponder Capacity Failure shall be measured from the time
Microspace receives notice from Customer of the Transponder Capacity Failure
until the time the Transponder has been restored to operation, but shall not
begin in any event until Customer ceases to use Customer's Transponder Capacity.

 Outage Allowance = Outage Allowance Failure Period (In Hours) X Monthly Lease

                                720 Hours/Month

           In no case shall an Outage Allowance be made for any Transponder
Capacity Failure related to: (i) any failure on the part of Customer to perform
its transmission or other material or operational obligations pursuant to this
Agreement, (ii) failure of facilities provided by Customer, (iii) reasonable
periodic maintenance, (iv) interference from third party transmissions or usage,
(v) cooperative testing, except where trouble or fault is found in the
Transponder or (vi) any other act or failure to act by Customer.

     5.02  Resolution of Credit Disputes.  In the event that Microspace and
           -----------------------------                                   
Customer cannot agree on the amount of credit due Customer following an
interruption, Customer may withhold payment of the disputed amount until
Microspace and Customer resolve the dispute; provided, however, that should a
credit dispute or disputes arise totaling two months Service fees or more in the
aggregate, Microspace or Customer may cancel this Agreement on thirty (30) days
written notice and pursue all legal remedies available to resolve the dispute,
including claims of breach for wrongful termination.

                                  ARTICLE VI

     6.01  Restoration of Service.  If Microspace's Transponder suffers a
           ----------------------                                        
Transponder Failure, Customer shall remain bound by this Agreement if
Microspace's Transponder is restored within two hundred forty (240) hours using
a Transponder Spare or unused transponder per the underlying lease agreement.

          If it is not so restored, Customer may terminate this Agreement
immediately and without any notice to Microspace.  In the event that the
Satellite is prematurely removed from service and if Microspace has, pursuant to
the underlying lease, preferential rights to replacement transponder capacity on
a successor satellite, Customer 

                                                                          Page 5

 
shall have the corresponding right to sublease transponder service from
Microspace on such successor satellite.

as soon as possible by telephone with prompt written confirmation of any
significant incidents that have been brought to its attention by GE which have a
material effect on Microspace's Transponder.  Microspace also shall notify

make it clearly ascertainable or predictable that any of the incidents described
in this section will occur.

     8.02  Maneuver Notification.  Microspace shall notify Customer of all non-

Notwithstanding any termination of this Agreement, Microspace and Customer shall

proprietary information, if the disclosing Party wishes to keep such information
proprietary under this Agreement. Any such information disclosed under this
Agreement shall be used by the recipient thereof only in its performance under
