ITEM 5. OTHER EVENTS

           On July 3, 1997, Lockheed Martin Corporation, a Maryland corporation 
("Lockheed Martin"), and Northrop Grumman Corporation, a Delaware corporation 
("Northrop Grumman"), issued a joint press release announcing that they had 
entered into an Agreement and Plan of Merger dated as of July 2, 1997. On 
September 29, 1997 Lockheed Martin and Northrop Grumman amended the July 2 
merger agreement in certain respects. A copy of the merger agreement, as so 
amended (the "Merger Agreement"), is attached hereto as Exhibit 99.1 and is 
incorporated herein by reference.

           The Merger Agreement, which is among Northrop Grumman, Lockheed 
Martin and Hurricane Sub, Inc. ("Lockheed Martin Merger Sub"), a Delaware 
corporation and wholly-owned subsidiary of Lockheed Martin, provides for the 
merger (the "Merger") of Lockheed Martin Merger Sub with and into Northrop 
Grumman, with Northrop Grumman surviving as a wholly-owned subsidiary of 
Lockheed Martin. Pursuant to the Merger Agreement, each share of common stock, 
par value $1.00 per share of Northrop Grumman ("Northrop Grumman Common Stock") 
outstanding immediately prior to the Effective Time (as defined in the Merger 
Agreement) of the Merger (other than shares held in Northrop Grumman's treasury)
will be converted into the right to receive 1.1923 shares of Lockheed Martin 
common stock, par value $1.00 per share ("Lockheed Martin Common Stock"). No 
fractional shares will be issued and cash, without interest, will be paid in 
lieu thereof. As of the Effective Time, all shares of Northrop Grumman Common 
Stock issued and outstanding immediately prior to the Effective Time will no 
longer be outstanding and will be automatically canceled and retired and will 
cease to exist, and each holder of a certificate or certificates which 
immediately prior to the Effective Time represented outstanding shares of 
Northrop Grumman Common Stock will cease to have any rights with respect 
thereto, except the right upon surrender of such certificate to (i) receive 
certificate(s) representing the number of whole shares of Lockheed Martin Common
Stock into which such shares of Northrop Grumman Common Stock have been 
converted and (ii) any cash, without interest, to be paid in lieu of any 
fractional share of Lockheed Martin Common Stock.

           The Merger Agreement has been approved by the respective Boards of 
Directors of Lockheed Martin and Northrop Grumman. The consummation of the 
Merger is subject, among other things, to the approval by the stockholders of 
Lockheed Martin of the issuance of the additional Lockheed Martin Common Stock 
to be issued, to the approval of the Merger by the stockholders of Northrop 
Grumman, and to certain regulatory approvals, and is expected to be completed in
the first quarter of 1998. The Merger will be accounted for using the purchase 
method of accounting.
