NORTHROP GRUMMAN INCREASES OFFER FOR TRW TO $53
- -----------------------------------------------

Amended Offer to Expire May 3, 2002

Los Angeles -- April 14, 2002 -- Northrop Grumman Corporation (NYSE: NOC)
announced today that it is amending its offer for TRW Inc. (NYSE: TRW) to $53
per share in value of Northrop Grumman common stock for each share of TRW. The
company also said it is extending its pending exchange offer to May 3, 2002 at
midnight EDT.

     Kent Kresa, Northrop Grumman chairman and chief executive officer, stated,
"We are increasing our offer for TRW due to improving economic conditions which
drive TRW's end markets and continuing positive developments in the defense
industry. We strongly encourage TRW shareholders to send a strong message to
their board of directors in favor of inviting us to conduct due diligence. If
the TRW board continues to deny us access, this offer will not proceed."

     Each share of TRW common stock may be exchanged for a number of shares of
common stock of Northrop Grumman equal to $53. The exact exchange ratio will be
determined by dividing the average of the closing price of Northrop Grumman
common stock for the five consecutive trading days ending immediately prior to
the second trading day period to the expiration of the offer, but in no event
will the number of Northrop Grumman shares exchanged be more



than 0.4690 ($53/$113) or less than 0.4309 ($53/$123). Each share of TRW's
Cumulative Serial Preference Stock II, $4.40 Convertible Series 1; and
Cumulative Serial Preference Stock II, $4.50 Convertible Series 3 may be
exchanged for a number of Northrop Grumman shares equal to the exchange rate
described above multiplied by the effective conversion rate for the shares of
preference stock. The amended offer is expressly subject to the condition that
Northrop Grumman has the opportunity to conduct a due diligence investigation of
non-public information concerning TRW, and its satisfaction with the information
provided.

     Prior to the amendment, approximately 1,980,244 shares of TRW common stock;
1,150 shares of Cumulative Serial Preference Stock II, $4.40 Convertible Series
1; and 2,630 shares of Cumulative Serial Preference Stock II, $4.50 Convertible
Series 3 had been tendered to Northrop Grumman as of 5:00 p.m. EDT on April 12,
