     LOS ANGELES -- March 30, 2001 -- Northrop Grumman Corporation (NYSE: NOC)
announced today that it received early termination notice yesterday from the
Federal Trade Commission under the Hart-Scott-Rodino Act for its proposed
acquisition of Litton Industries Inc. (NYSE: LIT).

     Previously, the European Commission approved the acquisition on

March 27, 2001, has been declared effective by the Securities and Exchange
Commission.  As a result, all U.S. and international governmental and regulatory
reviews that are required for the completion of the offer to purchase all
outstanding common and preferred stock of Litton have been received.

     Northrop Grumman also said it has extended its pending tender offer for
Litton's common and Series B preferred stock to April 2, 2001, at midnight
E.D.T., at which time the tender offer is expected to close.
