LOCKHEED MARTIN ANNOUNCES NEW ACCOUNTING STANDARD
WILL REQUIRE CHARGE IN FIRST QUARTER 1999


BETHESDA, MARYLAND, November 17, 1998  Lockheed Martin Corporation (NYSE: LMT)
today announced that, effective January 1, 1999, it will adopt a new accounting
standard pertaining to costs related to start-up activities.  The new standard,
Statement of Position (SOP) 98-5, issued by the American Institute of Certified
Public Accountants, requires that costs related to start-up activities be
expensed as incurred.

As a result, the Corporation will report a charge reflecting the initial
application of the standard as a cumulative effect of a change in accounting
principle (net of taxes) of approximately $350 million to $400 million in the
first quarter 1999.

Common examples of start-up activities include introducing a new product or
marketing an existing product to a new market segment; implementing a new
manufacturing process; and nonrecurring costs incurred before achieving a normal
capacity.  The Corporation has incurred significant start-up costs in the
aircraft and launch vehicle product areas, specifically on the C-130J and
commercial launch services programs; and in certain commercial and civil
government businesses.

The Corporation will incur a significant amount of start-up and development
costs in the launch services area, which includes the recent Air Force Evolved
Expendable Launch Vehicle (EELV) award.  Such costs will be expensed as
incurred.

In addition, the Corporation announced updates related to two other items
reported in the most recent Form 10-Q filed with the Securities and Exchange
Commission on November 2, 1998.  The Corporation has completed an evaluation of
the overall strategy and risks related to its launch vehicle line of business,
and concluded that no adjustments are required.  The Corporation also has
determined that it will complete the review of its relationship with CalComp
Technology, Inc., a majority-owned public subsidiary, in the fourth quarter
1998.

LOCKHEED MARTIN EXTENDS
COMSAT TENDER OFFER
UNTIL JANUARY 14, 1999


BETHESDA, Maryland, November 17, 1998 --Lockheed Martin Corporation (NYSE:LMT)
announced today that its wholly-owned subsidiary, Regulus, LLC, is extending its
offer to purchase up to 49% (less certain adjustments) of the outstanding shares
of common stock of COMSAT Corporation (NYSE:CQ) at a price of $45.50 per share,
net to the seller in cash, until 12:00 midnight, New York City time, on
Thursday, January 14, 1999.

The offer previously had been scheduled to expire on November 24, 1998.  The
terms of the extended offer otherwise remain the same as those of the original
offer as set forth in the offering materials filed with the Securities &
Exchange Commission on September 25, 1998.  The offer is being extended because
certain required regulatory and shareholder approvals have not yet been
obtained.

As noted in the offering materials, it is expected that a significant period of
time will elapse between the commencement and the consummation of the offer,
while the parties seek to obtain the regulatory approvals required in order to
satisfy the conditions to the offer.  The expiration date may be required to be
extended one or more additional times while such regulatory approvals are
sought.  In addition, in view of the need for U.S. congressional legislation
relating to the amendment or repeal of the Satellite Act, and for additional
regulatory approvals as conditions to the consummation of the merger, there may
be a further significant period of time between the purchase of shares pursuant
to the offer and the consummation of the merger.  There can be no assurance that
any such regulatory approvals will be obtained or that any such legislation will
be enacted, and if obtained and enacted, there can be no assurance as to the
date such approval and enactments will occur.

According to First Chicago Trust Company of New York, the depositary for the
offer, as of the close of business on November 16, 1998, 5,422,678 shares of
COMSAT Corporation common stock had been validly tendered and not withdrawn
pursuant to the offer.  None of these shares were tendered pursuant to notices
of guaranteed delivery.

The Information Agent for the offer is Morrow & Co., Inc. and questions about
the tender offer may be addressed to it at 1-800/566-9061.  The Dealer Manager
is Bear, Stearns & Co. Inc. and questions may be addressed to it at 1-877/762-
5237.

The proposed $2.7-billion Lockheed Martin/COMSAT strategic combination was
announced September 20, 1998.  Upon completion of the transaction, COMSAT will
become an integral element

 
of Lockheed Martin Global Telecommunications, a wholly owned subsidiary formed
to provide global telecommunications services to corporate and government
customers worldwide.
