     responsible party of the obligations that the law establishes as an

     presented.

     term of this Agreement for BESTEL's benefit.

     other method that the other party has received such notification.  In the

     at least fifteen (15) days advance notice; otherwise the latest address
     shall prevail.

     Guadalajara,, Mexico.

     to any of its subsidiaries or affiliates or guarantee any obligation
     through notification to the CUSTOMER.

<PAGE>

14   DISPUTE RESOLUTION.

14.1 The parties express their firm conviction that in good faith in the event
     there are differences or disputes because of the interpretation,
     fulfillment and execution of this Agreement and in unlimited form for any
     technical aspect, service provision, application and collection of
     consideration and any other that require specific technical capacity, they
     shall reasonably try to resolve in a friendly fashion through mediation
     and/or conciliation, voluntarily and previous to any other procedure that
     the parties could have and take place during a term of thirty (30) days in
     which the parties promote a mutual consulting process in order to resolve
     or avoid any controversy or dispute without waiving their rights.

14.2 It shall be considered that the attempts to reach a friendly solution have
     failed when one of the parties notifies the other party at the termination
     of such term that the negotiations have not been satisfactory; therefore
     the parties may execute their rights or effect any action as specified in
     this Agreement.

15.  ENTIRE AGREEMENT.

15.1 The parties agree that this Agreement and its Addenda constitute the only
     agreement and agree that this Agreement supersedes any agreement,
     communication, or proposal previously related with the objective of this
     Agreement.

The parties hereby agree and acknowledge this Agreement is subject to the terms
and conditions of any applicable regulations.  In the event such regulations are
not followed, the responsible party shall cure such failure without terminating
this Agreement unless such cure is not done in a reasonable time.

The parties execute this Agreement in duplicate in San Antonio, Texas on
September 28, 1998.
