(NYSE: NOC) Chairman and Chief Executive Officer Kent Kresa said today that,
"TRW shareholders have sent a strong message to TRW's board of directors today
in favor of allowing Northrop Grumman to begin due diligence in connection with
its proposed acquisition of TRW. We are prepared to immediately enter
discussions with TRW to resolve the outstanding differences concerning an
agreement that allows Northrop Grumman to begin due diligence consideration of
non-public information as soon as possible.

         "As we have previously stated, we are willing to pay full and fair
value for TRW and encourage TRW to provide information supporting any additional
hidden value. However, we need to conduct due diligence before we can enter into
substantive discussions that could lead to a negotiated transaction. We remain
confident that a combination of TRW and Northrop Grumman would be in the best
interests of TRW shareholders and employees," Kresa said.

         Northrop Grumman stated a combination of TRW and Northrop Grumman would
create a third major player in the growing defense space business, providing our

largest supplier of information technology services to the federal government.

         "Northrop Grumman has a great future, with or without TRW," Kresa said.
"As we have previously stated, we will not overpay, but we believe the
successful completion of this transaction is clearly in the long-term best
interests of TRW shareholders as well as Northrop Grumman shareholders," Kresa
