ACK/shs:  GCI.GX TSA.Orig         2         Thursday August 17, 1995 -- 3:30 pm

         3.01  Authority.  No Breach.  It has the right,  power and authority to
enter into, and perform its obligations  under,  this Agreement.  The execution,
delivery and  performance  of this  Agreement  shall not result in the breach or
nonperformance of any agreements it has with third parties.

         3.02  Corporate  Action.  It has  taken  all  requisite  corporate  (or
partnership,  as  appropriate)  action to approve the  execution,  delivery  and
performance of this Agreement, and this Agreement constitutes a legal, valid and
binding obligation upon itself in accordance with its terms.

         3.03 Common Clauses in Service Agreements. Contractor alone represents,
warrants  and agrees that it will  require,  in all service  agreements  between
itself and all other Transponder owners on the Satellite,  clauses substantially
identical to, or terms the effect of which shall be as or more  restrictive with
respect to such owners than,  the  provisions of Sections  3.06,12.01  and 13.08
hereof,  and Contractor will require,  in all service  agreements between itself
and other  Transponder  owners on the Satellite,  a clause  consistent  with the
provisions of Sections 4.02 and 4.03 hereof.

         3.04  Consents.  The  execution  and  delivery of this  Agreement,  the
performance  of  its  obligations   hereunder,   and  the  consummation  of  the
transactions contemplated hereby, will not result in a material violation of, or
material default under, or the occurrence of an event which with notice or lapse
of  time or  both  would  constitute  a  material  default  under,  or  material
noncompliance with, any applicable Law, any indenture,  mortgage, deed of trust,
loan  agreement,  purchase  agreement,  option  agreement or other  agreement or
instrument to which it is a party or by which it or any material  portion of its
property  is bound,  its  articles  of  incorporation  or  by-laws,  partnership
agreement,  or other  charter  documents,  as the case may be. All  necessary or
material  appropriate  public  or  private  consents,  permissions,  agreements,
licenses,  or  authorizations  to which it is  subject  in  connection  with the
transactions  contemplated  hereby,  or which it must  obtain  by  virtue of its
ownership or use of or operation of any  Transponder  or the Satellite have been
or shall be obtained in a timely manner.

         3.05 Litigation. To the best of its knowledge,  there is no outstanding
or  threatened  judgment,   threatened  or  pending  litigation  or  proceeding,
involving or affecting the  transactions  provided for in, or  contemplated  by,
this Agreement,  except as is concurrently  being disclosed in writing by either
party to the other.

         3.06 Non-Interference. Owner alone represents, warrants and agrees that
its radio  transmissions  (and those of its  uplinking  agents) to the Satellite
shall  comply,  in  all  material  respects,  with  all  Federal  Communications
Commission or any successor  agency  thereto  (collectively,  the "FCC") and all
other  governmental  (whether   international,   federal,  state,  municipal  or
otherwise) statutes, laws, rules, regulations, ordinances, codes, directives and
orders, of any such governmental agency,  body, or court (collectively,  "Laws")
applicable   to  it  regarding  the  operation  of  the  Satellite  and  Owner's
Transponder and shall not interfere with the use of any

ACK/shs:  GCI.GX TSA.Orig         3         Thursday August 17, 1995 -- 3:30 pm

other  Transponder.  Owner  shall  not  utilize  (or  permit or allow any of its
uplinking  agents to utilize) any of Owner's  Transponder in a manner which will
or may interfere with the use of any other Transponder or cause physical harm to
any of  Owner's  Transponder,  any  other  Transponders,  or to  the  Satellite.
Further,  Owner  will  coordinate  (and will  require  its  uplinking  agents to
coordinate)  with HCG, in accordance with procedures  reasonably  established by
HCG and  uniformly  applied  to all  owners  and  users of  Transponders  on the
Satellite,  its  transmissions  to the  Satellite,  so as to  minimize  adjacent
channel and adjacent satellite interference.  For purposes of this Section 3.06,
interference shall also mean acts or omissions which cause a Transponder to fail
to  meet  its  transponder  performance  specifications.  Without  limiting  the
generality of the foregoing,  Owner (and its uplinking agents) shall comply with
all  FCC  rules  and  regulations  regarding  the use of  automatic  transmitter
identification systems (ATIS).

efforts  throughout  the Service  Term to obtain and  maintain,  in all material
respects,  all federal,  state and municipal  authorizations  or  permissions to
operate the Satellite  applicable to Contractor  with respect to the  Satellite,
and to comply, in all material respects, with all such governmental  regulations
regarding the  operation of Owner's  Transponder  applicable to Contractor  with
respect to the Satellite.

         4.05 Tracking.  Telemetry and Control. Contractor shall employ at least
two earth stations  which between them shall provide in  conjunction  with HCG's
Operations Control Center in El Segundo, California, for all of the functions of

or  those of its  uplinking  agent to or from  the  Satellite  interfere,  under
standard  engineering  practice,  with the use of any  Transponder  not owned by
Owner  located on the  Satellite,  or if Owner or its uplinking  agent  utilizes
Owner's  Transponder in a manner which  interferes,  under standard  engineering
practice,  with the use of, or causes  physical  harm to, any other  Transponder
located on the Satellite,  and such radio  transmission  or utilization by Owner
does not cease  immediately  after the receipt of notice thereof from Contractor

         13.01  Entire   Agreement  and   Amendment.   This  Agreement  and  the
Transponder  Purchase  Agreement  constitute  the entire  agreement  between the
parties,   and   supersede   all   previous   understandings,   commitments   or
representations concerning the subject matter. This Agreement may not be amended

that the other party has not made any representations other than those which are
contained herein.

         13.02 Non-Waiver of Breach.  Either party hereto may specifically waive
any breach of this  Agreement by the other party,  provided  that no such waiver
shall be  binding  or  effective  unless in  writing  and no such  waiver  shall
constitute a continuing waiver of similar or other breaches. A waiving party, at
any time and upon notice  given in writing to the  breaching  party,  may direct
future  compliance  with the waived  term or terms of this  Agreement,  in which
event the breaching party shall comply as directed from such time forward.

         13.03 Notices.

         (a) Each party shall provide the other party with a telephone number to
     be  used  for  routine  and  emergency  operational  notifications,   which
     telephone shall be continuously staffed so as to enable the receipt of such
     notices  at all  times.  For  routine  notifications,  any such  telephonic
     notification shall be followed up with written  notification as outlined in

    obligations hereunder, provided, further, that Contractor shall not Transfer
    any of its obligations  under this Agreement to a non-Affiliate  except with
    the prior written consent of Owner,  which consent shall not unreasonably be
    withheld  or  delayed.  In the  event of any such  Transfer  by  Contractor,
    Contractor  shall  remain fully  liable for all its  obligations  under this
    Agreement.

         (c) Any purported  Transfer by either party not in compliance  with the

 Communications   Satellite  Services,  Inc.  ("HCSS").  This  letter  does  not
 supersede or amend the Agreement or the Service  Agreement,  but is intended to
 clarify  the  understanding  of HCG and  HCSS and  Buyer  with  respect  to the
 following   provisions  of  the  Agreement  and  the  Service  Agreement.   All
