Attention: Mr. Marcus Bennett

Dear Marc:

      Reference is made to (i) the Contribution and Assumption Agreement dated
October 31, 1997 between Lockheed Martin Corporation ("LM") and LMT Sub Inc.
(the "Contribution Agreement") and (ii) the Exchange Agreement dated  October
31, 1997 among General Electric Company ("GE"), GE Investments, Inc., GE
Government Services, Inc., Client Business Services, Inc., LM and LMT Sub Inc.
(the "Exchange Agreement").  All terms used and not otherwise defined herein
have the meanings set forth in the Contribution Agreement.

      This letter is intended to set forth certain agreements between LM
and GE in connection with the Contemplated Transactions and, for purposes
of the Transaction Documents, shall constitute an agreement contemplated by
the Transaction Documents.

      1. GE and LM hereby agree that for so long as the aggregate principal
amount outstanding of the loans referred to in Section 4.09 of the Contribution
Agreement is at least $1,000,000,000, GE shall be entitled, at its option, to
propose to the nominating committee of the Board of Directors of LM one
individual for nomination as a director of LM, subject to the approval of the
nominating committee and the Board of Directors of LM.  LM will advise GE
promptly of the approval or nonapproval of any proposed nominee so that an
alternative can be selected in the event of nonapproval.  In the event of
nonapproval, GE and LM agree that a representative of GE and a member of the
nominating committee will discuss and use their best efforts to agree upon an
acceptable nominee.  In the event an acceptable nominee cannot be agreed upon
in such discussions, LM will identify as acceptable nominees three individuals
who are directors or senior executive officers of GE and from that group GE
will select its nominee.  Once an acceptable nominee has been agreed upon, LM
will use its best efforts to cause 

 
the nomination and election of that person as a director of LM and continue such
person in office during the period provided herein. As of the Closing, the
person so designated by GE is Eugene F. Murphy, Vice Chairman of GE and a
current member of the LM Board of Directors.

      2. This letter agreement shall terminate upon the termination of the
Exchange Agreement in accordance with Article 10 thereof.
