Northrop Grumman today announced that it continues to anticipate a
fourth quarter 2002 closing of its proposed acquisition of TRW Inc.
. A 30-day waiting period related to a Second Request for
Information under the Hart-Scott-Rodino Anti-Trust Improvements Act of 1976
expired at midnight Oct. 15. The Justice Department, however, continues to
review the proposed transaction.

Northrop Grumman has agreed with the Justice Department not to close the
proposed acquisition without providing the Department with proper notice.
Such notice will be given no sooner than 10 business days prior to the earlier
of Northrop Grumman’s or TRW’s shareholders’ meeting regarding the
acquisition. According to the company, the agreement is not unusual, and
allows the Department of Justice sufficient time to conclude an orderly review
of the transaction.

Northrop Grumman and TRW jointly announced July 1 that they had entered
into a definitive merger agreement. Under the terms of the agreement,
Northrop Grumman will acquire TRW for $60 per share in common stock in a
transaction valued at approximately $7.8 billion, plus the assumption of TRW’s
net debt at the time of closing.

The exact exchange ratio will be determined by dividing $60 by the average
of the reported closing sale prices per share of Northrop Grumman common stock
on the New York Stock Exchange for the five consecutive trading days ending on
and including the second trading day prior to the closing of the merger. The
exchange ratio will not be less than 0.4348 or more than 0.5357 of a Northrop
Grumman share.
