                                  ARTICLE IV
                                  ----------

                         SERVICE PERFORMANCE; CREDITS
                         ----------------------------

     4.01  Microspace will provide Service on the Serving Transponder that meets
the Minimum Performance Standards set forth in Exhibit(s) A and B as measured on
equipment meeting all technical requirements of the FCC or other government
agency for satellite earth stations. For any period during which a Serving
Transponder fails to meet the Minimum Performance Standards set forth in
Exhibit(s) B and during which time Customer ceases to use the Service on that
Transponder (such period is a "Service Interruption"), Microspace will

                                                                               3

 
give Customer a credit allowance as described below. Failure of a Serving
Transponder to meet the Minimum Performance Standards does not constitute a
Service Interruption when due to any of the following causes:

           (a) The failure or non-performance of any Customer-provided earth
               stations, facilities or equipment;

           (b) The fault, negligent act, or failure to act of Customer, its
               employees, or agents;

           (c) Sun outages, rain fade, or externally caused interference, other
               than interference caused by GTE, or by its other customers, in
               their use of GTE Satellite facilities;

           (d) Suspensions or terminations of Service made in accordance with
               this Agreement.

     4.02  The duration of a Service Interruption is measured from the earlier
of the time that Microspace is Notified by Customer of a suspected Service
Interruption or Microspace otherwise becomes aware of a Service Interruption,
until the time the affected Serving Transponder again meets the Minimum
Performance Standards, or until the Service is otherwise restored on a
Transponder Meeting Minimum Performance Standards.  Customer shall give
Microspace notice of any Service Interruption as is reasonably possible, along
with all relevant facts of which Customer is aware concerning such Interruption.
Any such notice may be given to Microspace verbally pursuant to Paragraph 16.08,
"Notices".

     4.03  Microspace will give Customer a credit allowance for every minute of
Service Interruption in excess of a cumulative total of five (5) minutes of
Service Interruption in any calendar month.  Any credit allowance granted under
this Agreement will be determined by Microspace as follows:

                          CREDIT ALLOWANCE = T x (M/Q)

     Where - "T" is the number of minutes for which credits are to be calculated
     pursuant to this Agreement; and

     "M" is the Service Charge applicable to the affected Service as provided in
     Exhibit(s) B; and

     "Q" is the number of minutes in a month.  For the purpose of this
     Agreement, Q = 43,200.

     Credits will be provided within ninety (90) days of the event giving rise
     to the right to such credit.  If, after the expiration of this Agreement,
     Customer has not utilized credits granted pursuant to this Section, and
     subject to payment of all sums due Microspace under this Agreement and all
     other agreements between Customer and Microspace, Microspace will refund to
     Customer the balance of such credits.

     4.04  Microspace will grant Customer a credit in accordance with Paragraph
4.03 above for the period of time when Customer's use of the 

                                                                               4

 
Serving Transponder is interrupted due to Service Testing or Emergency Testing
as described in Paragraph 5.03.

                                   ARTICLE V

                          SERVICE OUTAGE AND FAILURE
                          --------------------------

     5.01  A "Service Outage" shall be deemed to have occurred if (i) one or
more Service Interruptions of one (1) minute or more in duration occur on the
affected Serving Transponder during any consecutive seven hundred twenty (720)
hour period, and (ii) the aggregate of all such Service Interruptions on the
affected Serving Transponder during such period exceeds one hundred twenty (120)
minutes.

     5.02  Except as provided in Paragraph 5.03 below, a Serving Transponder
shall be deemed to have failed (a "Service Failure") if:

           (a) GTE fails to restore the affected Serving Transponder to meet the
               Minimum Performance Standards within 24 hours of the occurrence
               of a Service Outage; or

           (b) GTE determines that the affected Serving Transponder cannot be
               restored to meet the Minimum Performance Standards within 24
               hours of the occurrence of a Service Outage; or

           (c) the affected Serving Transponder is restored to meet the Minimum
               Performance Standards within 24 hours of the occurrence of a
               Service Outage and during the 720 hour period following any such
               restoration, the affected Serving Transponder again experiences a
               Service Outage.

     5.03  The following shall not constitute a Service Failure:

           (a) Service Testing.  Service Testing may be performed only after a
               minimum of 24 hours prior notice to Customer and after reasonable
               efforts to coordinate such testing with Customer to minimize
               disruption of its use of the Service. Such testing shall be
               limited to circumstances in which testing is necessary to
               maintain or initiate new service on the Serving Satellite, to
               properly coordinate with other satellite users or operators, or
               to otherwise prudently manage the Satellite while minimizing
               Service Testing to the greatest extent possible.

           (b) Emergency Testing.  Emergency Testing may be performed only for
               the purpose of restoring, or determining the cause of, a failure
               of a component or subsystem on the Serving Satellite, or in
               response to an order of a court or the FCC, or to determine the
               cause or source of interference.

                                                                               5

 
           (c) A Service Interruption that would otherwise qualify as a Service
               Failure but for the fact that such Service Interruption resulted
               from a Force Majeure as defined in Article VII.

           (d) A Control Outage as defined in Article VI.

                                  ARTICLE VI

                                CONTROL OUTAGE
                                --------------

     6.01  If a Service Interruption occurs due to loss of control of the
Serving Satellite and the Service is not restored within a period of less than
one hundred twenty (120) hours from the start of such Service Interruption, a
"Control Outage" shall be deemed to have occurred, and this Agreement may be
terminated in accordance with Article X, "Termination and Suspension". During
the period of such Service Interruption that Service is not available and until
any Control Outage is deemed to have occurred, Microspace's obligation to
provide Service and Customer's obligation to pay for Service not yet provided on
the affected Serving Transponder(s) shall be suspended.  Microspace will provide
to Customer a credit allowance in accordance with Paragraph 4.03 for any
payments received by Microspace for Service that is not provided during such
suspension.

                                  ARTICLE VII

                                 FORCE MAJEURE
                                 -------------

     7.01  Except as provided in Paragraph 7.02 below, Microspace shall not be
liable for:  (i) the unavailability of the Service; or (ii) Service
Interruptions (other than for the granting of credits pursuant to Article IV,
"Service Performance; Credits") resulting from causes beyond its commercially
reasonable control, including, but not in any way limited to, the order of a
court or other government agency, or by operation of any law or regulation. Each
such event shall constitute a Force Majeure.

     7.02  In the event of:

           (a) The unavailability of the Service due to an event of Force
               Majeure; or

           (b) The failure of a Transponder to meet the Minimum Performance
               Standards that would otherwise qualify as a Service Failure but
               for the fact that such failure resulted from a Force Majeure.

          Microspace's obligation to provide Service and Customer's obligation
to pay for Service not yet provided on the affected Serving Transponder will be
suspended until (i) the Service is available or is restored; (ii) Microspace
offers to provide Service on the same Serving Satellite on a

                                                                               6

 
Transponder of the same Transponder Class meeting the Minimum Performance
Standards ("Alternative Service"); or (iii) five (5) days have elapsed,
whichever first occurs. If within such five (5) day period, the Service is
available or the affected Serving Transponder is restored to meet the Minimum
Performance Standards or Microspace offers Alternative Service, the Parties'
obligations with respect to the affected Serving Transponder under this
Agreement shall be reinstated for the remainder of the Term of this Agreement.
If, within such five (5) day period, the Service is not available, the affected
Serving Transponder is not restored to meet the Minimum Performance Standards,
or Microspace does not offer Alternative Service, the affected Service may be
terminated by either Party as provided in Article X, "Termination and
Suspension". Microspace will provide to Customer a Credit allowance in
accordance with Paragraph 4.03 for any payments received for Service by
Microspace that is not provided during such suspension.

     7.03  For the purpose of this Article VII, an irreparable satellite
component failure shall not be deemed a Force Majeure, regardless of the cause
of such failure, if the failure is of a type and mode that would have been
correctable through the use of the Spare Components on the Serving Satellite as
such components existed at the time of launch of the Satellite.

                                 ARTICLE VIII

                              SERVICE PROTECTION
                              ------------------

     8.01  The Service Protection level provided by Microspace is a Protected
Service.

           (a) "Protected Service" means service that entitles Customer to
               restoration (subject to payment of all sums due Microspace for
               Service rendered) of the affected service within 24 hours of the
               occurrence of a Service Failure through the use of the Serving
               Satellite's available Spare Components, unassigned Transponders,
               or Transponders used to provide Preemptible Service (but not
               those Transponders specifically reserved for restoration of
               service of a particular customer or customers) of the same
               Transponder Class as the Transponder on which the Service Failure
               has occurred for so long as there remain available Spare
               Components, unassigned Transponder, or Transponders used to
               provide Preemptible Service on the Serving Satellite.  Protected
               Service will not be preempted except as provided in Paragraph
               12.03 below.

           (b) Restoration is provided to customers taking Protected Service
               (and those who have otherwise contracted for restoration of
               service) on the basis that the customer who first requires
               restoration shall be first restored utilizing the then-available
               complement of Spare Components, unassigned Transponders or
               Transponders used to provide Preemptible 

                                                                               7

 
The information below marked by [**] has been omitted pursuant to a request for 
confidential treatment. The omitted portion has been separately filed with the 
Commission.


               Service of the same Transponder Class as the Transponder on which
               the Service Failure has occurred. The number of available Spare
               Components, unassigned Transponder, and Transponders used to
               provide Preemptible Service may be insufficient to guarantee one-
               for-one restoration for each customer entitled to restoration and
               is subject to change as a result of Satellite equipment failure,
               or in the case of unassigned Transponders and Transponders used
               to provide Preemptible Service, prior assignment, reservation, or
               sale to another customer, making such Transponders unavailable to
               Customer for restoration. The decision to the particular means of
               restoration shall be exclusively GTE'S, and both Microspace and
               Customer must comply with their decision. Any customer taking
               Protected Service or that has otherwise contracted for
               restoration may be determined by GTE, in GTE's sole discretion,
               to require restoration within the meaning of this Article VIII
               and in accordance with Article V, "Service Outage and Failure"


                                 ARTICLE IX

                              CHARGES AND PAYMENT
                              -------------------

     9.01  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 16.08 and shall be deemed to be made upon receipt thereof by
Microspace. Microspace shall assess a late payment charge of one and one-half
percent (1.5%) compounded monthly on payments received after the due date.

     9.02  Deposit.  No deposit is required.
           -------                          

   
     9.03  [**] Microspace will not [**] to any other person or entity [**] 
than those applicable to [**] hereunder. Should Microspace provide [**], 
this Agreement shall be amended to provide Customer with [**] for the remainder 
of the term of the Agreement; provided, however, that this provision will not 
apply with respect to [**] Capitol Broadcasting Company or any subsidiary 
thereof.
    

                                                                               8

                          TERMINATION AND SUSPENSION
                          --------------------------

     10.01 Termination by Customer.  Anything set forth herein to the contrary
notwithstanding, upon the occurrence of any of the following events Customer may
terminate this Agreement within ninety (90) days of actual knowledge of the
events giving rise to the right to termination:

           (a) Breach or Default.  If Microspace commits a material breach or
               default of any of the provisions of this Agreement and such
               breach or default has not been cured within thirty (30) days
               after receipt by Microspace of Customer's notice of such breach
               or default; provided, however, that Customer may terminate this
               Agreement immediately in the event that a Transponder Failure is
               not corrected within one hundred twenty (120) hours as provided
               in Paragraph 7.02 above.

           (b) Government Restrictions.  If the performance of this Agreement
               pursuant to the terms hereof has been prohibited by any federal,
               state or local court, governmental or regulatory body, and
               Service has been interrupted for a period of one hundred twenty
               (120) hours or more as a result.

     10.02 Termination by Microspace with Notice.  Anything set forth herein to
the contrary notwithstanding, upon the occurrence of any of the following events
Microspace may terminate this Agreement upon ten (10) days prior notice of
intent to terminate to Customer:

           (a) Breach or Default.  If Customer commits a material breach or
               default of any of the provisions of this Agreement, including,
               but not limited to a failure to pay timely the monthly charge due
               under Article IX, and such breach or default has not been cured
               within thirty (30) days after receipt by Customer of Microspace's
               notice of such breach or default;

           (b) Governmental Restriction.  If performance of this Agreement
               pursuant to the terms hereof has been prohibited by an federal,
               state or local court, governmental or regulatory body, and
               performance by Customer has been interrupted for a period of one
               hundred twenty (120) hours or more as a result.

     10.03 Termination by Microspace without Notice.  Microspace can terminate
this Agreement immediately if the underlying transponder lease between
Microspace and GTE terminates for reasons beyond the control of Microspace.
Termination of the GTE lease shall not be deemed to be beyond the control of
Microspace if it results from a default of said lease by Microspace and said
default has been acknowledged as such in writing by Microspace or judicially
determined to be such.

                                                                               9

 
     10.04 Either Party may terminate this Agreement:

           (a) on written notice to the other Party with respect to Service on
               an affected Transponder in the event of: (a) a Service Failure on
               a Transponder providing Protected Service which cannot be
               restored by GTE in accordance with Article VIII; or (b) a Service
               Interruption that would otherwise qualify as a Service Failure
               but for the fact that such Service Interruption resulted from a
               Force Majeure for which Alternative Service is not offered by
               Microspace within the five-day period specified in Paragraph
               7.02; or

           (b) on written notice to the other Party with respect to a Serving
               Satellite in the event of (a) a Control Outage as defined in
               Article VI; or (b) retirement of the Serving Satellite in
               accordance with the following:

               (i)   Fifty percent (50%) or more of the Transponders on the
                     Satellite have failed or are unusable for any reason; or

              (ii)   In the event that the Satellite's station-keeping fuel
                     becomes depleted to a level sufficient only to ensure
                     removal of the Satellite from its assigned orbital
                     position; or

             (iii)   If required to do so by any governmental authority; or

              (iv)   If special circumstances require retirement, and such FCC
                     authority as is required for retirement is obtained.
                     Microspace will use its best efforts to provide Customer
                     written notice of any final decision to retire the Serving
                     Satellite effective prior to the expiration of this
                     Agreement as far in advance of the date of retirement as
                     the circumstances allow.  Upon retirement of the Serving
                     Satellite, all future performance obligations under this
                     Agreement hereunder shall terminate.

           (c) in the event of a material breach by the other Party for which no
               cure period is specified herein if such breach continues for a
               period of thirty (30) days after notice of intention to terminate
               is given by the non-breaching Party.

     10.05 In addition to its rights under Paragraph 10.02 above, Microspace may
terminate this Agreement on written notice of:

           (a) Customer's non-payment of sums due Microspace; or

           (b) use of the Service in a manner which violates any applicable law,
               rule, or regulation; or

                                                                              10

 
           (c) if the event giving rise to the notice of termination is not
               cured within five (5) days following the date of such notice.

     10.06 In addition to its rights under Paragraph 10.01 above, Customer may
on written notice to Microspace terminate this Agreement within fifteen (15)
days of the date of receipt of notice from Microspace that the Serving Satellite
is to be relocated as provided in Paragraph 12.02 below if, as a result of such
relocation, the Serving Transponder will not meet the Minimum Performance
Standards.

     10.07 In the event this Agreement is terminated by either Party, Customer
shall cease using the Service provided pursuant to this Agreement and shall pay
(i) all charges and/or fees due Microspace (including late payment charges) up
to the date of termination; plus (ii) any sums due Microspace pursuant to
Article IX and Article XI; less (iii) any payments made to Microspace by
Customer for Service not yet provided, including any remaining Security Deposit
or Advance Payment which has not otherwise been applied by Microspace to payment
of sums due Microspace, or any unused credit allowances due Customer, whereupon
all future performance obligations under this Agreement of the Parties hereunder
shall terminate.

     10.08 Damages.  A termination of this Agreement under Sections 10.01(a) and
           -------                                                              
10.02(a) shall not limit a Party's right or ability to recover damages
occasioned to such Party as a result of the other Party's breach of this
Agreement.

                                   ARTICLE XI

                  INDEMNIFICATION AND LIMITATION OF LIABILITY
                  -------------------------------------------

     11.01 Limitation of Liability.
           ----------------------- 

           (a) Neither Party shall be liable for any failure of performance
  hereunder due to causes beyond its control, including but not limited to acts
  of God; fire, flood or other catastrophes; any law, order, regulation,
  direction, action or request of the United States government, or of any other
  government, including state and local governments having jurisdiction over
  such Party, or of any department, agency, commission, bureau, corporation or
  other instrumentality of any one or more said governments, or of any civil or
  military authority, national emergencies, insurrections; riots, wars, or
  strikes, lockouts, work stoppages or other labor difficulties;

           (b) Except with respect to an intentional breach by Microspace of
  Section 2.02, the liability of Microspace for damages or losses of any kind
  arising out of its furnishing Service to the Customer hereunder shall not
  include consequential damages, as defined in Section 2.02 above;

                                                                              11

 
           (c) Microspace shall not be liable for any act or omission of any
  other entity furnishing to the Customer facilities or equipment used with the
  Service nor shall Microspace be liable for any damages or losses due to the
  fault or negligence of the Customer or to the failure of Customer-provided
  equipment or facilities.

     11.02 Indemnification by Customer.  Customer shall indemnify and hold
           ---------------------------                                    
  Microspace and its affiliates, its and their officers, employees or agents, or
  any of them, whether acting through Microspace or otherwise, harmless from and
  against:

           (a) Use by Customer.  All loss, liability, damage and expense,
               ---------------                                           
  including reasonable counsel fees due to claims for libel, slander,
  infringement of copyright arising from the material transmitted by Customer
  over Microspace's facilities; and any other claim resulting from any negligent
  or wrongful act or omission of Customer or patrons of Customer and relating to
  the Service furnished by Microspace;

           (b) Misrepresentation, Breach, etc.  Any and all damages occasioned
               -------------------------------                                
  by, arising out of or resulting from any material misrepresentation,
  intentional breach of warranty or covenant, or intentional default or
  intentional nonfulfillment of any agreement on the part of Customer under this
  Agreement or under any certificate, agreement, exhibit, schedule or other
  instrument furnished to Microspace pursuant to this Agreement or in connection
  with any of the transactions contemplated hereby;

           (c) Defense of Third Party Claims.  Microspace shall notify Customer
               -----------------------------                                   
  within ten (10) days of its being served with a lawsuit, and otherwise within
  thirty (30) days of its actual knowledge of the occurrence of any event, or of
  its discovery of any facts, which in its opinion entitle or may entitle it to
  indemnification from a third party claim under this Article. Microspace's
  failure to do so shall preclude it from seeking indemnification hereunder
  unless such failure has not prejudiced the Customer's ability to defend such
  claim. Customer shall promptly defend such claim by counsel of its own
  choosing at its own cost and expense and Microspace shall cooperate with
  Customer in the defense of such claim including the settlement of the matter
  on the basis stipulated by Customer (with Customer being responsible for all
  costs and expenses of such settlement). If Customer within reasonable time
  after notice of a claim fails to defend Microspace, Microspace shall be
  entitled to undertake the defense, compromise or settlement of such claim at
  the expense of and for the account and risk of Customer;

           (d) Right to Defend.  If there is a reasonable probability that
               ---------------                                            
  resolution of a claim in the manner provided in paragraph (c) above will
  materially and adversely affect Microspace, Microspace shall have the

                                                                              12

 
  right, at its own cost and expense, to defend, compromise or settle such claim
  against it;

          (e)  Claim Against Third Party.  If the facts giving rise to
               -------------------------                              
  indemnification hereunder shall involve a possible claim by Microspace against
  a third party, Microspace shall have the right, at its own costs and expense,
  to undertake the prosecution, compromise and settlement of such claim;

          (f)  Release.  Customer shall not, without Microspace's consent,
               -------
  settle or compromise any claim or consent to any entry of judgment which does
  not include as a term thereof an unconditional release by the claimant or
  plaintiff of Microspace from all liability with respect to such claim.

                                  ARTICLE XII
                                  -----------

                             SATELLITE OPERATIONS
                             --------------------

     12.01 Nothing in this Agreement shall be construed to prevent GTE from
taking any action necessary to protect its Satellite(s) or to implement its
obligations under Article VIII hereof on a non-discriminatory basis to all
Protected Service customers or those customers otherwise contracting for
restoration, or to act in accordance with the Operations Procedures.

     12.02 GTE reserves the right to relocate the Serving Satellite in
accordance with applicable regulations of the FCC or other governmental agencies
having jurisdiction.  Prior to any such relocation of the Serving Satellite, GTE
will give Microspace, and Microspace will give Customer, notice of the
Satellite's new location, a schedule for such relocation, and whether the
Serving Transponder(s) will continue to meet the Minimum Performance Standards.
Thereafter, unless this Agreement is Terminated in accordance with Article X,
the rights and obligations of the Parties under this Agreement shall continue.
During the period that Service is not available and until any relocation is
completed, GTE's obligation to provide Service shall be suspended, and
Microspace will provide to Customer a credit allowance in accordance with
Paragraph 4.03 for any payments received by Microspace for the Service that was
unavailable due to the relocation; provided, however, that if Alternative
Service is offered by Microspace and accepted by Customer for this period, a
credit allowance will not apply.

     12.03 Customer acknowledges and agrees that it may be necessary in unusual
or abnormal situations or conditions for Microspace to deliberately interrupt
Customer's use of the Serving Transponder in order to protect the overall
performance of the Serving Satellite, which situations may include, without
limitation, telemetry indications of spacecraft system malfunctions during or
near periods of eclipse, indications of attitude control or maneuver
malfunctions, or power subsystem anomalies. Such decision shall be made by
Microspace in its sole discretion. To the extent technically feasible,
Microspace

                                                                              13

 
shall give Customer as much prior notice of such interruption as is practicable
and Microspace will use its best efforts to consult with Customer and to
schedule and conduct its activities during periods of such interruption so as to
minimize the disruption of Customer's use of the Serving Transponder.  Customer
agrees that the interruption, for reasons stated in this paragraph, of
Customer's use of the Transponder on which Service is being provided shall not
be deemed a Service Failure, and Microspace's sole liability for any such
interruption shall be the issuance of credits as described in Article IV.

                                 ARTICLE XIII
                                 ------------

                                 SEVERABILITY
                                 ------------

     13.01 In the event any one or more of the provisions of this Agreement
shall for any reason be held to be invalid or unenforceable, the remaining
provisions of this Agreement shall be unimpaired, and the invalid or
unenforceable provision shall be replaced by a provision which, being valid and
enforceable, accurately reflects the intention of the Parties underlying the
invalid or unenforceable provisions.

                                  ARTICLE XIV
                                  -----------

                                    CLAIMS
                                    ------

     14.01 The failure of either Party to insist upon strict adherence to any
provision of this Agreement on any occasion shall not be considered a waiver of
any right thereafter to insist upon strict adherence to that provision or any
other provision of this Agreement.  Any and all claims arising under this
Agreement, except claims for non-payment of sums due, shall be brought within
one (1) year of the date that the circumstances giving rise to such claim first
occurred.

                                  ARTICLE XV

                                   SURVIVAL
                                   --------

     15.01 Termination of this Agreement by either Party for whatever cause
shall not affect any provision of this Agreement which, by its nature, is
intended to survive or operate in the event of termination and shall not
prejudice or affect the rights of either Party against the other with respect to
any breach of this Agreement which may have been committed prior to the date of
any such termination.  Subject only to the foregoing sentence, both Parties
shall in the event of any such termination be discharged from all of their
respective obligations under this Agreement which were due to have been
performed after the date of any such termination.

                                                                              14

     16.01 Public Notice, Confidentiality and Proprietary Information.
           ----------------------------------------------------------  
Notwithstanding any termination of this Agreement, Microspace and Customer shall
hold in confidence the information contained in this Agreement, and Microspace
and Customer hereby acknowledge that all information related to this Agreement
is confidential and proprietary and is not to be disclosed to third persons,
without the prior consent of both Microspace and Customer.  Neither Microspace
nor Customer shall disclose to any third party (other than GTE) the existence
of, or any of the terms and provisions of, this Agreement except as provided in
this Section 16.01.  Neither Party shall issue a public notice or a news release
concerning this Agreement and the transactions contemplated hereby without the
prior approval of the other Party, which approval shall include the right to
approve the form, content and timing of any such release.  To the extent that
either Party discloses additional information which it considers proprietary, it
shall identify such information as proprietary when disclosing it to the other
Party by marking it clearly and conspicuously as proprietary information;
provided, however, that Microspace understands and agrees that the names and
locations of Customer's patrons and affiliates are confidential and proprietary
and need not be identified as such at the time of disclosure to Microspace.  Any
proprietary disclosure to either Party, if made orally, shall be promptly
confirmed in writing and identified as 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 this Agreement.
Notwithstanding the foregoing, neither Party shall be liable for disclosure or
use of such proprietary information (but shall notify the other Party prior to
such disclosure or use) which is:

          (a) Applicable Law.  Required to be disclosed to the extent necessary
              --------------

disclosures from the disclosing Party when such development can be documented to
have occurred prior to a disclosure.  No license to the other Party, under any
patents, is granted or implied by conveying proprietary information or other
information to that Party.

          Notwithstanding the foregoing, the existence (but not the material
terms) of this Agreement may be disclosed to the patrons and affiliates of
Customer to the extent necessary to establish proper transmission of music and
other communications services to such individuals and entities through the
leased transponder channels.

Party of any noncompliance hereunder, and no failure on the part of either Party
to exercise its rights hereunder shall prejudice any remedy for any subsequent
noncompliance, and any waiver by either Party of any breach or noncompliance
with any term or condition of this Agreement shall be limited to the particular
instance and shall not operate or be deemed to waive any future breaches or
noncompliance with any term or condition.  All remedies and rights hereunder and
those available in law or in equity shall be cumulative and the exercise by a
Party of any such right or remedy shall not preclude the exercise of any other
right or remedy available under this Agreement in law or in equity.
