Northrop Grumman Encourages TRW's Board To Act in the Best Interests of TRW
Shareholders

     LOS ANGELES -- March 13, 2002 -- Northrop Grumman Corporation (NYSE: NOC)
issued the following statement in response to TRW's (NYSE: TRW) announcement
earlier today:

     "Northrop Grumman remains fully committed to its previously announced
exchange offer to acquire TRW. If TRW's board and management want to maximize
shareholder value, as they stated in today's release, then we would encourage
them to sit down with us immediately to begin the process of negotiating a
transaction that is in the best interests of the shareholders of both our
companies," said Kent Kresa, chairman and chief executive officer. "While we
continue to believe that our offer represents full and fair value based on
analysis of the available public data, TRW continues to hold us at arm's length
and deny us access to information that could support its claim that an offer of
greater value is warranted.

     "Furthermore, we believe that TRW and its shareholders should recognize
that our offer has a higher degree of certainty, can be rapidly completed and
poses far less risk than any of the alternatives suggested in its announcement
today. TRW promises to explore a variety of contingent actions, which may lead
to the separation of its

                                                                          Page 2

automotive and aerospace businesses while arguing that its shareholders should
hold out hope that these potential actions can deliver value. In contrast,
Northrop's proposal represents a single, coherent, well-defined transaction that
will provide excellent value immediately while also providing TRW shareholders
the opportunity to participate in the exciting future growth potential of
Northrop Grumman.

     "As to any conditions attached to our offer, it should be clear that only
TRW's board has the ability to create near-term value by removing the principal
conditions through immediately entering into good faith negotiations and
allowing Northrop Grumman to conduct its due diligence. Not doing so only serves
to hinder the realization of value for TRW shareholders.

     "A Northrop Grumman/TRW combination makes eminent strategic sense and will
bring together our two companies' complementary defense capabilities," said
Kresa. "Over the years, we are very proud of the fact that we have built a major
tier-one defense company. This has been accomplished by first identifying and
then successfully integrating new businesses into the Northrop Grumman family.
We have also consistently delivered shareholder value not only to our
shareholders but to the shareholders of these acquired companies," concluded
Kresa.

Background of Offer
-------------------

     On Feb. 22, 2002, Northrop Grumman announced a proposal to combine with TRW
in a transaction that would deliver $47 in value of Northrop Grumman common
stock for each share of TRW. Promptly following the close of the transaction,
Northrop Grumman would expect to separate TRW's automotive business. On March 3,
2002, Northrop Grumman announced that it was commencing an exchange offer for
all outstanding shares of common stock and preference stock of TRW Inc., in
order to take
