          II.4   That its use of the Services provided pursuant to this
                 Agreement will be limited to those private communications
                 necessary to the conduct of Customer's commercial activities.

                                    CLAUSES

     1.   The Customer agrees to install and maintain the Equipment as part of
the "turn-key" telecommunications services (the "Services"), specified in
Addendum 1, to be provided to Customer, whose address and service locations are
listed on Addendum 1. Upon execution by Customer and acceptance by Company, this
document becomes a binding contract between them. The term "Customer" shall
include all subsidiaries of Customer.

     2.   TERM. This Agreement shall terminate sixty (60) months from the date
Customer accepts the Services per paragraph 4, except as provided otherwise
herein.

     3.   CUSTOMER'S COMMITMENT. Customer hereby agrees to pay the amounts
specified in Addendum 2 for the Services for the term of this Agreement and to
perform the obligations specified in Paragraph 11 below.

     4.   INSTALLATION SERVICES. The Company will install the Equipment at the
Customer sites designated in Addendum 1, will perform site surveys and will make
all necessary filings required in connection with the installation of the
Equipment and operation of the Services, including those with the Mexican
government. Prior to the installation by the Company, Customer shall have
completed its obligations specified in Paragraph 11 below, and shall have
notified the Company in writing of such completion. Upon completion of
installation, Company and Customer shall conduct all such tests as either
reasonably deems necessary to confirm operation of the Equipment and Services.
Acceptance by Customer shall mark the beginning of the term established by
paragraph 2, and billing of the Base Monthly Service Charges shall commence as
of that date.

     5.   SERVICE PERFORMANCE. The Services shall have a digital bit error rate
of 10/7/ or better, per circuit ("Service Performance Standards"). The Company
states, and Customer acknowledges, that satellite signal transmission services
within the United States of Mexico are, by Mexican law, provided exclusively by
a dependency of the Mexican government. Notwithstanding this, however, the
Company shall be responsible for managing the satellite spectrum allocated to
Customer and for ensuring that such signal transmission services (as well as
other Services provided hereunder) are provided in accordance with the Service
Performance Standards. A "Service Interruption" shall occur for the period of
time that the Services fail to meet the Service Performance Standards. A Service
Interruption begins when the Company independently becomes aware of a Service
Interruption or when the Company acknowledges Customer's notification of

                                    Page 2

            12500 NETWORK BLVD., SUITE 407 SAN ANTONIO, TEXAS 78249

- --------------------------------------------------------------------------------

Service Interruption and ends at the time that the Services have been restored
to applicable Service Performance Standards. Company shall immediately
acknowledge notification of a Service Interruption upon receipt of notice from
Customer. If a Service Interruption occurs of greater than four (4) continuous
hours during the normal business hours, Customer shall be credited against its
Base Monthly Service Charge for the month next following for each hour the
Service Interruption continues based on a 720-hour month. A failure to meet the
applicable Service Performance Standards will not constitute a Service
                                              ---
Interruption when that failure is the result of any of the following causes:

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

     (b)  An act or failure to act of Customer, its employees, or agents;

     (c)  Customer-requested Service or Equipment modification;

     (d)  Suspensions or terminations of Service made in accordance with these
standard terms and conditions;

     6.   MAINTENANCE; OUTAGE RESPONSE PROCEDURE.  The Company shall provide all
necessary and required maintenance, including regular, scheduled maintenance for
the Equipment pursuant to this Agreement and in consideration for the Base
Monthly Service Charge specified in Addendum 2.  When the Company receives
notification or independently becomes aware of a service problem, Company shall
immediately begin diagnostic efforts to isolate the source of the service
outage.  If dispatch of service personnel is required, such personnel shall be
dispatched within a reasonable period of time and in accordance with commercial
transportation schedules.  The Company shall use all commercially reasonable
efforts to remedy the service problems as soon as possible.  Unless approved in
writing by Company, no party other than Company or its designee shall provide
any maintenance, installation or repair services in connection with the
Equipment or Services.

     7.   RENEWAL.  This Agreement will be renewed automatically at the end of
the initial sixty (60) months for additional terms of twelve (12) months
unless, not less than ninety (90) days before the expiration of the then-
effective term, either party notifies the other in writing of its intention not
to renew.

     8.   CHARGES AND PAYMENT.

     The Base Monthly Service Charge specified in Addendum 2 is payable in
advance each month during the Term of this Agreement.  The Base Monthly Service
Charge for less than a full month will be prorated on a thirty (30) day month
basis.  Company shall invoice Customer at the beginning of each month for
charges due for such month and Customer

late payment charge calculated on the outstanding balance then due, with such
late payment charge equal to the maximum late-payment charge allowable under
Texas law, up to 1.5 percent per month on the unpaid balance.

    9.    ASSIGNMENT. Neither party shall assign this Agreement without the
prior written consent of the other party, which consent will not be withheld or
