For Immediate Release

NORTHROP GRUMMAN RESPONDS TO
- ----------------------------
DISTRICT COURT RULING ON TRW SPECIAL MEETING
- --------------------------------------------

         LOS ANGELES -- April 19, 2002 -- Northrop Grumman Corporation
(NYSE: NOC) released the following statement concerning the decision of the
United States District Court permitting TRW to delay until May 3, 2002, the
Special Meeting of TRW Shareholders which had been scheduled for Monday, April
22.

         Kent Kresa, chairman and chief executive officer of Northrop Grumman,
stated: "After Northrop Grumman received the Institutional Shareholder Services
(ISS) endorsement for the Control Share Acquisition proposal, which was to be
voted on April 22, we are naturally disappointed that TRW has deliberately
chosen to put off the meeting for another 10 days. It is unfortunate that the
District Court was unwilling to prevent this obvious delaying tactic. In any
event, we have elected not to appeal the District Court's ruling since it would
not now be possible to reinstate the Special Meeting without creating further
confusion among TRW's shareholders."

         "We hope that TRW shareholders understand that they still have the
opportunity to express their wishes next week, at the regular Annual Meeting of
TRW shareholders on April 24. At the Annual Meeting, Northrop Grumman will
submit three proposals for

shareholder vote, all of which provide stockholders the opportunity to send a
strong message to the TRW board of directors in favor of providing non-public
information to Northrop Grumman and entering into good faith negotiations for a
mutually agreeable transaction between the two companies."

         "It has now been almost two months since Northrop Grumman proposed an
acquisition of TRW, and TRW has still not provided us an opportunity to review
the non-public information which they claim would justify a higher price than
Northrop Grumman has offered."

         Kresa added, "ISS has recommended that TRW shareholders vote for two of
the three Northrop Grumman proposals:

         .  the resolution to provide non-public information, and

         .  the resolution to establish a committee of independent directors"

         "Now that the Special Meeting of Shareholders has been postponed,"
Kresa concluded, "it is more important than ever that shareholders return their
green proxy card to vote for the Northrop Grumman proposals at the Annual
Meeting on April 24."
