PERMISSION GRANTED BY THE FEDERAL GOVERNMENT THROUGH THE MINISTRY OF
COMMUNICATIONS AND TRANSPORTATION (HEREIN "THE MINISTRY"), TO SATELITRON, S.A.
DE C.V. (HEREIN "SATELITRON"), TO INSTALL, OPERATE AND EXPLOIT AN EARTH STATION
NETWORK TO DELIVER THE SERVICES OF NATIONAL DEDICATED LINKS THROUGH NATIONAL
SATELLITES OR THOSE DETERMINED BY THE FEDERAL GOVERNMENT, IN COMPLIANCE WITH THE
FOLLOWING BACKGROUND AND CONDITIONS.

BACKGROUND

I.   The National Development Plan 1989-1994 establishes the importance of
     modernizing telecommunications for national development, and stresses the
     need to diversify services, improve quality and widen its coverage with a
     greater participation by individual parties.

II.  The Telecommunications Modernization Program 1989-1994 established the need
     to promote the development of new services in competition, that may take
     advantage of the capacity installed from national satellites and complement
     the basic telecommunications services in the country.

III. In addition, said program considers the possibility to have
     telecommunications companies install and operate base earth stations or
     teleports and terminal VSAT stations located in the user's facilities that
     allow the establishment of links and private networks sharing the
     satellite's capacity.

IV.  "SATELITRON", through writing dated on July 2, 1989 required "THE MINISTRY"
     permission to install, operate and exploit a multyuser master earth station
     and remote earth stations in several points of the national territory, that
     will use public satellite signal conduction services under charge of the
     Federal Government.

V.   "THE MINISTRY", taking into account that "SATELITRON" fulfilled and
     satisfied the legal and technical requirements, pursuant to the previous
     background and founded on Articles 36 of the Organic Law of Public Federal
     Administration, as well as Articles 3rd, 9th, and, 11th and others
     pertaining to the General Law of Channels of Communication, supported in
     Articles 6th, 34, and 58 fraction II of the By-law of Telecommunications,
     grants the following:
<PAGE>   4
                                   PERMISSION

To install, operate and exploit an earth station network (herein "THE NETWORK")
to deliver the services of dedicated links with national satellites or those
determined by the Federal Government, in accordance to the technical frequencies
and parameters contained in Annex 1 which forms part of this document. "THE
NETWORK" will be integrated in a first stage by the following earth stations.

1.   A high capacity master earth station in Mexico City to deliver the services
     of dedicated links and private networks by national satellites to carry
     voice, data and videoconference signals through low capacity
     terminal-earth-station exchanges VSAT's located in the user's facilities
     that allows it to share the use of the base earth station and the capacity
     of satellites.

2.   Three medium capacity semi master earth stations that will be installed in
     Monterrey, N.L., Guadalajara, Jal. and Hermosillo, Son. to carry voice,
     data and videoconference signals through low capacity terminal earth
     stations VSAT's located in the user's facilities that allow it to share the
