For Immediate Release

NORTHROP GRUMMAN AND TRW NOTIFY JUSTICE DEPARTMENT

OF INTENT TO COMPLETE MERGER

LOS ANGELES — Nov. 27, 2002 — Northrop Grumman Corporation (NYSE: NOC) and TRW Inc. (NYSE: TRW) jointly announced today that, in accordance with their agreement with the U.S. Department of Justice, they notified the Department of their intention to complete their merger transaction on Dec. 11, 2002. Northrop Grumman reports that it believes, based on discussions with the Department of Defense, that the Defense Department has recommended to the Justice Department that the transaction proceed. The recommendation is subject to the execution of a consent decree ensuring fair and open competition with respect to certain satellite technologies.

Northrop Grumman also reported that late Tuesday it had received a draft of the consent decree from the Justice Department and believes that an agreed upon version can be achieved in time to support the shareholder votes on Dec. 11, 2002. The company stated that the draft consent decree does not require the divestiture of any businesses.

OF INTENT TO COMPLETE MERGER

The Hart-Scott-Rodino antitrust review waiting period expired Oct. 15, 2002, and the European Union antitrust authority approved the transaction Oct. 16, 2002.

“Phil Odeen and I are pleased that the merger between Northrop Grumman and TRW is being viewed favorably by government officials and we look forward to the successful completion of the transaction,” said Kent Kresa, Northrop Grumman chairman and chief executive officer. He added, “We are working with the Department of Justice to implement arrangements that ensure fair and open competition in space electronics. Competition is a precept to which we at Northrop Grumman are firmly committed. We look forward to successful shareholder votes on December 11, 2002, and the close of the transaction immediately thereafter.”

Once agreement is reached on the terms of the proposed consent decree, the Justice Department must file it with the federal district court together with a Competitive Impact Statement. The court approval of the consent decree cannot occur until after the expiration of a 60-day public comment period. TRW and Northrop Grumman, however, expect to be in a position to close the transaction with TRW immediately following successful shareholder votes on Dec. 11, 2002, without waiting for final court approval.
