LOS ANGELES, May 1, 2002 -- Northrop Grumman Corporation (NYSE:NOC) today said that it has sent the following letter to TRW Inc. (NYSE:TRW) concerning the "standstill" provision of the confidentiality agreement:

May 1, 2002

  Mr. William Lawrence
 Executive Vice President
 Planning, Development and Government Affairs
 TRW Inc.
 1900 Richmond Road
 Cleveland, Ohio 44124

Dear Mr. Lawrence:

Your press release earlier today seriously distorts the facts. Last week, Northrop Grumman offered in writing to accept a short standstill period of 75 days and to participate in any reasonable process which TRW might establish for the consideration of competing offers. TRW declined to discuss the terms we suggested and, instead, responded Friday night with a slightly different version of the 3-year standstill agreement. In fact, TRW has yet to suggest, verbally or in writing, any standstill period less than three years. It is quite clear from your letter yesterday that TRW has no intention of softening its insistence on a lengthy standstill period, despite your statement that you "believe we can address the standstill period's length to some extent."

If that is not, in fact, TRW's position I would urge you to clarify the matter without delay.

Very truly yours,

W. Burks Terry
