              Re:    Application of Maritime Telecommunications Network, Inc.
                     Call Sign E010332
                     FCC File Number SESL1C2001113002259

      Dear Ms. Dortch:

            On January 16, 2004, Maritime Telecommunications Network, Inc. (“MTN”), through counsel,
      provided letters to the parties copied below in connection with MTN’s pending Earth station
      application referenced above. These letters were provided at the request of the Federal
      Communications Commission and enclosed technical information concerning MTN’s plans to use
      this Earth station to communicate with the Satmex 5 satellite, which is located at 116.8 degrees W.L.

             Subsequent to the filing of these letters, and pursuant to discussions between and among
      representatives of Satmex and Telesat, MTN discovered errors in the technical information provided
      in its technical assessment enclosed with its January 16, 2004 letters. MTN attaches to this letter a
      corrected technical annex that supersedes and replaces the one it provided with its January 16, 2004
      letters to the parties below. MTN understands that with the filing of this corrected annex, Telesat no
      longer objects to the grant of the referenced application.

              Please contact undersigned counsel with any questions regarding this matter.

                                           Respectfully submitted,




                                           Counsel to Maritime Telecommunications Network, Inc.
