 Item 5.  Other Events

      Senator Conrad Burns, Chairman of the Senate Subcommittee on
 Communications, sent a letter to William E. Kennard, Chairman of the
 Federal Communications Commission (the "FCC") on August 13, 1999 indicating
 his hope that the FCC would act in a timely manner on the application by
 Lockheed Martin Corporation ("Lockheed Martin") to acquire 49 percent of
 COMSAT Corporation ("COMSAT" or the "Company").

       Senator Burns and Representative Tom Bliley, Chairman of the House
 Committee on Commerce, had previously requested in a letter to Mr. Kennard
 on January 21, 1999 that the FCC withhold action on Lockheed Martin's
 application prior to Congress adopting satellite reform legislation.

      An industry publication has reported that a draft order concerning the
 applications of the Lockheed Martin and its subsidiary, Regulus LLC, filed
 with the FCC (a) to effect a transfer of control of COMSAT Government
 Systems, Inc. ("CGSI") and become a common carrier and (b) to acquire 49
 percent of the Company through classification as an authorized common
 carrier, were put on circulation at the FCC late Tuesday, August 17, 1999.
 Under typical FCC procedures, commissioners vote on orders put on
 circulation within 30 days, although there is no legal requirement that the
 commissioners do so.  In addition, a meeting of the commissioners of the
 FCC is scheduled for September 15, 1999.  It is possible that the
 applications may be scheduled for consideration at the September 15
 meeting.  If the FCC acts in accordance with its past practices, the agenda
 for that meeting would typically be released by September 8, 1999.  Neither
 the Company nor Lockheed Martin knows whether the application will be
 scheduled to be considered at the September 15 meeting or whether the
 commissioners will vote on the circulated order in accordance with the
 FCC's 30 day procedure, although, either course would allow the FCC to act
 upon the applications prior to September 18, 1999. The Company and Lockheed
 Martin have each stressed to the FCC the importance of action prior to this
 date, however, there can be no assurance that the FCC will act before
 September 18, 1999 or that any action will be favorable.

      COMSAT shareholders voted to approve the merger agreement with
 Lockheed Martin at COMSAT's 1999 Annual Meeting of Shareholders held on
 August 20, 1999.

      On August 27, 1999, Lockheed Martin issued a press release pursuant to
 which it announced that the tender offer had been extended until 12:00
 noon, New York City time on Saturday, September 18, 1999.  The terms of the
 extended tender offer otherwise remain the same as those set forth in
 Lockheed Martin's Offer to Purchase filed with the Securities and Exchange
 Commission on September 25, 1998.

      Lockheed Martin has previously disclosed that it had negotiated terms
 with the Department of Justice (the "DOJ") which could form the basis of a
 consent order that would resolve concerns raised by the DOJ staff in the
 Hart-Scott-Rodino antitrust review process as to Lockheed Martin's
 simultaneous ownership of shares of Loral Space & Communications Ltd.
 ("Loral Space") and, following the consummation of the tender offer,
 COMSAT.  The proposed consent order contemplated that Lockheed Martin would
 divest its ownership interest in Loral Space.  As previously disclosed,
 however, Lockheed Martin has stated that its willingness to enter into a
 consent order reflecting the terms negotiated was conditioned upon Lockheed
 Martin's reaching certain agreements with Loral Space that would offer
 Lockheed Martin assurances satisfactory to it that it could accomplish the
 divestiture in accordance with the terms and conditions and within the time
 periods contemplated by the proposed consent order.  Lockheed Martin has
 advised COMSAT that it has been unable to obtain these assurances from
 Loral Space.

      In addition, as previously disclosed, Lockheed Martin and COMSAT have
 each received requests for additional information from the DOJ in response
 to their filings with the DOJ of the notices required by the Hart-Scott-
 Rodino Antitrust Improvements Act of 1976.  The receipt of these requests
 extends the waiting period (prior to which the companies may not complete
 the tender offer or the merger under without violating the antitrust laws)
 until the 20th calendar day after each company substantially complies with
 the request directed to it.  Also disclosed was that Lockheed Martin and
 COMSAT had each provided data to the DOJ responsive to the requests for
 additional information but that neither had supplied all of the information
 requested.  In view of the status of Lockheed Martin's discussions with
 Loral Space, Lockheed Martin and COMSAT determined to provide the DOJ with
 the remaining materials responsive to the requests for additional
 information.

      On August 27, 1999, each company supplied the additional materials and
 certified that it was in substantial compliance with the request directed
 to it.  In conjunction with the production by Lockheed Martin and COMSAT of
 the additional information and the certifications of substantial
 compliance, the staff of the DOJ has requested depositions of
 representatives of Lockheed Martin and COMSAT.  Substantial compliance with
 the DOJ's requests for information starts the running of a 20 calendar day
 waiting period which the companies anticipate will expire at midnight New
 York City time on September 16, 1999.  The DOJ has the authority terminate
 this waiting period early.  If prior to the expiration of the waiting
 period, the DOJ does not challenge compliance by either or both companies
 with the DOJ's requests for information, the waiting period will expire. In
 addition, the DOJ has the authority to bring an action alleging that the
 proposed transactions would be likely to lessen competition in violation of
 the antitrust laws.  The expiration or termination of the waiting period is
 one of conditions to the tender offer.

      Neither Lockheed Martin nor COMSAT knows whether or not the DOJ will
 terminate the waiting period early, will allow the period to expire or will
 challenge compliance by either or both companies with the DOJ's requests
 for information or will elect to bring an action challenging the
 transaction as violating the antitrust laws before the expiration of the
 waiting period.
