                                              Exhibit 1


      AT&T Corp. ("AT&T") is planning to offer a new Experimental Mobile Service using C—
      band frequencies via INTELSAT Satellites in the Pacific Ocean Region (POR) to and
      from ships at sea for Voice, Fax, Data and Video Transmission.

      The elements of the proposed experimentation will include:

             (1) 2.0 meter C—band U.S. registered ship antennasauthorized under CFR
                 47 part 5 ( not i ncluded in this arp heation       )X          .

             (2) Onshore Earth Station owned by AT&T in      sait Creek, CA

             (3) Space Segment to be leased by AT&T from Comsat World Systems

             (4) Terrestrial Connection to the public switched telephone network

             (5) Satellites INTELSAT V, VI, and VII series in the AOR and POR

      The objectives of the experimentation will be to:

             (1) Determine the ability of enhanced gyroscope stabilizing mechanisms used
                  to stabilize 2.0 meter C—band Antennas for use on seagoing vessels that
                  can qualify for certification under INTELSAT standards

             (2) Determine if there is C—band interference

             (3) To analyze AT&T‘s role in providing two—way space segment

             (4) Access service quality using C—band frequencies in a maritime environment

             (5) Evaluate calling patterns to obtain valid information

      AT&T‘s program of experimentation will foster the development of a new service and
      contribute valuable information on the use of Fixed Space Satellite (FSS) frequencies in
      the maritime environment used in conjunction with Shipboard Earth Stations.

      temporary usage of frequencies for periods less than seven (7) days.
      However, the Licensee(s) shall maintain accurate station records of
      the times and particulars of such temporary frequency usage.

      The authority granted here is limited to the operation of the
      facilities described above and does not include any authority to
      install and operate channelizing equipment or any other authority
      under Section 214 of the Communications Act of 1934, as amended, to
      establish channels of communication.

      With respect to potential co—channel interference to or from
      terrestrial microwave radio stations, the transmit and receive
      frequency bands listed in this license have been cleared for
      transmissions to and from satellites located in the geostationary
      orbit for the emissions designated in Section 1 of this license.

      Upon completion of the station, the Licensee(s) must file with the
      Commission a certification including the following information: The
      name of the Licensee, file number of the application, call sign of
      the antenna, date of the license, a certification that the facility
      as authorized has been completed, that each antenna facility has
      been tested and is within 2 dB of the pattern specified in Section
      25.209, and that the station is operational including the date of
      commencement of service, and will remain operational during the
      license period unless the license is submitted for cancellation. A
      copy of the certification shall be sent to the Engineer—in—Charge of
      the Field Office responsible for the radio district in which the
      station is located.   Call Enforcement Division of Field Operations
      Bureau at (202) 418—1150 if you cannot determine your district.

      Obstruction marking and lighting specifications are required in
      accordance with the following paragraphs of FCC Form 715: None.

      All operations shall be on a common carrier basis.

                       operate the station or any right in the use of the frequencies
                       designated in the license beyond its term or in any other
                       manner than authorized in the license;

              2.       Neither the license nor the right granted under it shall be

6.   PROVISIQNS FOR LICENSE (cont.)
     C.   The Licensee(s) shall maintain on file with the Commission a
          current list or plan of the precise frequencies in use at the
          station,  specifying for each frequency the RF center
          frequency, polarization, emission designator, nominal E.I.R.P.
          (in d@BW) and maximum E.I.R.P. density (in dBW/4kHz).                      This
          list or plan may be submitted either on a station—by—station
          basis or on a system—wide basis and shall be updated within
          seven (7) days of any changes in frequency usage at this
          station.  The Licensee(s) need not notify the Commission of
          temporary usage of frequencies for periods less than seven (7)
          days.      However,    the        Licensee(s)    shall    maintain    accurate
          station records of the times and particulars of such temporary
          frequency usage.

          In   the    event     of    the   failure   of   a   satellite     with   which
          operations are authorized in Section 2(a) of this license,
          operations are authorized in conjunction with any INTELSAT
          satellite in the affected Ocean Region that provides any
          authorized services herein in order to maintain the continuity
          of  commercial  service;  provided  that  the  Licensee(s)
          immediately notify the Commission of the nature of this
          emergency and its expected duration; and provided that the
          operational      limits      of    elevation     angle    and   azimuth   range
          specified in Section 1 of this license are not exceeded.    In
          the event that such emergency operations require emissions not
          specified in Section 1 of this license, such emissions may be
          utilized provided that the E.I.R.P.‘s of such emissions do not
          exceed the limits set forth in this license.

          The authority granted here is limited to the operation of the
          facilities described above and does not include any authority
          to install and operate channelizing equipment or any other
          authority under Section 214 of the Communications Act of 1934,
          as amended, to establish channels of communication.

          With respect to potential co—channel interference to or from
          terrestrial microwave radio stations, the transmit and receive
          frequency bands listed in this license have been cleared for
          transmissions   to and   from   satellites  located in    the
          geostationary orbit for the emissions designated in Section 1
          of this license.

          Upon completion of the station, the Licensee(s) shall certify
          in writing to the            Commission that      all    terms,   conditions,
          obligations and technical parameters set forth in the
          Commission‘s authorization and inthis license have been fully
          met.   A copy of the certification shall be sent to the
          Engineer—in—Charge of the Field Office responsible for the
          radio   district       in    which    the   station      is   located.    Call
          Enforcement Division of Field Operations Bureau at                        (202)
          418—1150 if you cannot determine your district.

                                                     frequencies designated in the license beyond its term or
                                                     in any other manner than authorized in the license;

                                           2.        Neither the license nor the right granted under it shall
                                                     be assigned or otherwise transferred in violation of the

                                                     Commission‘s Rules and Regulations issued under it; and

                                          3.         This station is subject to the right of use or control

                                J.        This license shall be forfeited automatically if this station
                                          is not ready for operation within the time specified below
