For Immediate Release


         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.

                                    - more -

                                                                          Page 2


Very truly yours,

W. Burks Terry
