PERMIT GRANTED BY THE FEDERAL GOVERNMENT THROUGH THE MINISTRY OF COMMUNICATIONS
AND TRANSPORTATION (THE "MINISTRY") TO SERVICIOS DE INFRAESTRUCTURA, S.A. DE
C.V., ("SINFRA") TO INSTALL, OPERATE AND EXPLOIT AN EARTH STATION OR TELEPORT
NETWORK TO PROVIDE DEDICATED DOMESTIC PRIVATE LINE SERVICES THROUGH THE NATIONAL
SATELLITES OR THOSE DETERMINED BY THE FEDERAL GOVERNMENT IN ACCORDANCE WITH THE
FOLLOWING ANTECEDENTS AND CONDITIONS:

                                  ANTECEDENTS

I.      The National Plan of Development 1989-1994 establishes the importance of
        the modernizing telecommunications for National Development and
        emphasizes the need to diversify services, improve quality and expand
        coverage with more participation of individuals.

I.      The Telecommunications Modernization Program 1989-1994 establishes the
        need to promote the development of new services in competition that
        utilize the existing capacity of the national satellites and complement
        the country's basic telecommunication services

I.      As well, such program considers the possibility for telecommunication
        entities to install and operate master earth stations or teleports and
        very small aperture terminals (VSAT's) located at the customer's
        facilities that allow the establishment of circuits and private networks
        sharing the satellite's capacity.

I.      On March 30, 1994 SINFRA submitted a request to the Ministry for a
        permit to install, operate and exploit a network integrated by a master
        earth station and remote earth stations in several areas throughout
        Mexico, that would use the satellite capacity under the charge of the
        Federal Government.

The Ministry acknowledges that SINFRA satisfies the technical and legal
requirements, in accordance with the antecedents mentioned above and with
Article 36 of the Federal Public Administration Law, 6th Section X of the
Internal Regulations of the Ministry, 3rd, 9th, and 11th of the General
Communications Law, 6th, 34th and 58th Section II of the Telecommunications
Regulations, and hereby grants the following:

                                    PERMIT

To install, operate and exploit an earth station network (the "Network") to
provide dedicated services through the national satellites or those determined
by the Federal Government in accordance with the technical parameters specified
in Addendum 1 of this permit. The Network will be designed as follows in its
first phase:

A Master Earth Station located in Mexico City to provide dedicated services and
private networks via national satellites to provide voice, data and
videoconferencing services through VSAT's located at the customer's facilities
that will allow the shared use of the master earth station and satellite
capacity.
