For Immediate Release

NORTHROP GRUMMAN PROPOSES TO ACQUIRE TRW
----------------------------------------

         LOS ANGELES -- Feb. 22, 2002 -- Northrop Grumman Corporation
(NYSE: NOC) today announced that it has forwarded a proposal (see attached) to
TRW's (NYSE: TRW) board of directors to enter into negotiations to combine the
two companies. The proposed transaction would deliver $47 in value of Northrop
Grumman common stock for each share of TRW.

         "We believe the strategic combination of Northrop Grumman and TRW will
provide tremendous value to the shareholders of both companies," said Kent
Kresa, Northrop Grumman's chairman and chief executive officer. "Northrop
Grumman's electronics and systems integration capabilities, combined with TRW's
space and systems expertise, would create a strong contributor to the nation's
satellite and missile defense requirements.

         "This combination would further our long-term strategic goals by
strengthening our space business, adding communications technology and
capabilities, and enhancing our information technology business," Kresa added.
"We expect that, once we reach a timely agreement with the TRW board of
directors, we will be able to close this transaction in the 2002 third quarter."

         Ronald D. Sugar, Northrop Grumman's president and chief operating
officer, stated "this transaction would strengthen our portfolio, and would
bring together the

advanced technologies and extraordinary human talent of both companies. With the
integration of our 2001 acquisitions largely behind us, we are confident that
our management, in conjunction with the leadership of TRW, can quickly and
successfully integrate the defense and aerospace businesses of Northrop Grumman
and TRW."

         Promptly following the close of the transaction, Northrop Grumman would
expect to separate TRW's automotive business. Excluding TRW's automotive
business, Northrop Grumman projects combined 2003 sales of approximately $26
billion to $27 billion. The impact of this transaction is expected to be neutral
to Northrop Grumman shareholders when considering the earnings delivered by both
the retained and automotive businesses.

         Including the effects of this transaction, Northrop Grumman would
expect to have a debt to total capitalization ratio below 40 percent at 2002
year-end.

         TRW provides advanced-technology products and services for the
aerospace, information systems and automotive markets worldwide. The company
generated year-end 2001 sales of $16.4 billion.

         Northrop Grumman Corporation is an $18 billion, global defense company
with its worldwide headquarters in Los Angeles. Northrop Grumman provides
technologically advanced, innovative products, services and solutions in defense
and commercial electronics, systems integration, information technology and
nuclear and non-nuclear shipbuilding and systems. With nearly 100,000 employees
and operations in 44 states and 25 countries, Northrop Grumman serves U.S. and
international military, government and commercial customers.

February 21, 2002


Philip A. Odeen
Office of the Chief Executive
Kenneth W. Freeman
Lead Director
TRW Inc.
1900 Richmond Road
Cleveland, OH  44124

Gentlemen,

As you know from prior conversations between our companies, for quite some time
we have believed that a merger of the TRW Inc. ("TRW") aerospace and information
systems businesses with the complementary operations of Northrop Grumman
Corporation ("Northrop") would be a compelling strategic combination in the best
interests of stockholders, customers and employees of both corporations. I am
writing at this time to formally propose a transaction for this purpose.

Based upon publicly available information, Northrop is prepared to provide all
TRW stockholders with $47.00 in Northrop common stock for each share of TRW
common stock. The transaction will be structured so that the receipt of Northrop
stock by TRW stockholders will be tax-free. The proposed $47.00 per share of TRW
common stock represents a premium of 18% over today's closing price, a premium
of 22% over the average trading price for the last twelve months and is 4% over
the highest closing price for the last twelve months. We would welcome the
opportunity to consider non-public information concerning TRW, and we are
prepared to consider in our offer any enhanced values that may be demonstrated
by such information. Naturally, we are prepared to provide TRW and its
representatives with a similar "due diligence" opportunity concerning Northrop
non-public information.

Upon completion of the acquisition transaction, it is Northrop's intention to
proceed with the separation of the TRW automotive business from the rest of the
company immediately. We recognize that the automotive business is an outstanding
operation in its own right, but we believe that it does not logically fit with
either your or our other business segments.

Northrop has successfully completed the integration of many large acquisitions
in recent years, and I believe we have earned the reputation for recognizing the
continuing value and contribution of the executives of those acquired companies.
We have also demonstrated fairness and evenhandedness in dealing with employees
of the acquired companies and for scrupulously observing employees' rights to
compensation and benefits.



Northrop is prepared to begin immediately with the due diligence process and
negotiation of a definitive acquisition agreement for the approval of our
respective Boards of Directors. With full cooperation from both sides, we can
conclude our agreement no later than March 11, 2002 and commence immediately the
necessary proceedings for stockholder approval in accordance with Ohio law and
for approval of our own stockholders. Our antitrust counsel has advised us that
delays in connection with the antitrust review process should be minimal; and we
believe a transaction could realistically be completed in the third quarter of
this year.

Ron and I sincerely believe that a combination of TRW's aerospace and
information systems businesses with our own will maximize the opportunities to
enhance the value of those operations for the benefit of all our stockholders.
Not only are the operations highly complementary, but the TRW operations will
enjoy the support of a stronger balance sheet.

In light of the importance of this proposal to Northrop's shareholders, we will
be publicly disclosing this letter. Should you have any questions concerning our
offer, I and our representatives are prepared to speak with you at any time. We
would appreciate your response to this offer by the close of business February
27, 2002.

                                                     Sincerely,


                                                     /s/ Kent Kresa

                                                     Kent Kresa
