TRW BOARD REJECTS NORTHROP GRUMMAN PROPOSAL

CLEVELAND, March 3, 2002 - TRW Inc. (NYSE: TRW) announced today that its board
of directors has unanimously determined to reject Northrop Grumman Corporation's
(NYSE: NOC) proposal set forth in its letter dated February 21, 2002 to acquire
all of the outstanding shares of TRW for $47 per share in Northrop Grumman
stock. After careful consideration, including consultation with independent
financial and legal advisors, the TRW board of directors concluded that Northrop
Grumman's proposal was financially inadequate. The board noted its belief that
the Northrop Grumman proposal grossly undervalues TRW's advanced portfolio of
technology and market leadership positions in space, defense, information
systems and automotive parts, and is not consistent with the board's objective
of enhancing shareholder value.

"This is all about shareholder value," said Philip A. Odeen, TRW's chairman,
"and the Northrop Grumman proposal does not begin to recognize the value of
TRW's franchise."

Following is a letter sent today from TRW chairman Philip A. Odeen and lead
director Kenneth A. Freeman to Kent Kresa, chairman and chief executive officer
of Northrop Grumman.

                                  March 3, 2002

     Mr. Kent Kresa

     Chairman of the Board and Chief Executive Officer
     Northrop Grumman Corporation
     1840 Century Park East
     Los Angeles, CA 90067

     Dear Mr. Kresa:

     The board of directors of TRW has met to consider Northrop Grumman's
     February 21 proposal to acquire TRW for $47 per share in stock.

     After careful consideration, including a thorough review of the proposal
     with our independent financial and legal advisors, the board has determined
     not to pursue discussions with regard to Northrop Grumman's proposal.
     Simply put, the board has unanimously concluded that Northrop Grumman's
     proposal is financially inadequate. We believe Northrop Grumman's proposal
     grossly undervalues TRW's businesses, including its premier franchise in
     the defense industry, does not adequately reflect the true value of our
     unique market position and business opportunities, and is not consistent
     with our objective of enhancing shareholder value.

                                     (more)



                                     Page 2

     In making this determination, and based on your letter, we have assumed
     that the $47 per share would be in fixed value and that the timing or
     closing of such transaction would not be conditioned in any way upon the
     separation of our automotive business. Accordingly, our board has
     determined that there is no reason to explore Northrop Grumman's proposal
     further.

     The board views Northrop Grumman's proposal as an opportunistic attempt to
     acquire one of the industry's leading space and electronics and systems
     businesses at a time when TRW's stock price was temporarily depressed after
     the sudden departure of David Cote, our former chairman, president and
     chief executive officer. In addition, as of March 1, 2002, TRW's stock
     price closed at $50.05 per share, over $3 per share higher than Northrop
     Grumman's proposal.

     TRW is positioned for future technology-driven growth. Our space and
     defense businesses are in the "sweet spot" of growth in national defense
     and homeland security. Our aeronautical business is a global leader in
     control systems and product support and is well positioned for growth as
     the commercial aerospace sector continues to rebound. Our global automotive
     business is a market and technology leader in our product segments and is
     generating strong cash flow, even at the bottom of the automotive cycle. We
     have been driving cost reductions and productivity improvements, while
     creating a customer-focused, performance-driven culture. Over the past
     three years, we have reduced net debt by $3.9 billion. In 2001, we exceeded
     earnings expectations for each quarter and are on track to meet 2002
     expectations.

     We are confident in TRW's ability to continue to take the steps necessary
     to fully realize the value of our franchise. Toward this end, the board's
     executive search committee, comprised of outside directors, has selected a
     prominent executive search firm and is actively engaged in a search for a
     new chief executive officer. As you know, TRW has an experienced senior
     management team and an outstanding employee base. We are 94,000 strong
     worldwide and our employees are highly committed to the company and their
     customers in the aerospace, systems and automotive businesses. With our
     unparalleled technologies and market leading positions, we are confident
     that great things can continue to be expected from TRW.


     Sincerely,



     //s// Philip A. Odeen               //s// Kenneth W. Freeman
