TRW Board Rejects Northrop Grumman Proposal

TRW Inc. announced today
that its board of directors has unanimously determined to reject Northrop
Grumman Corporation’s 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 EastLos 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.

     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 ligain 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
