Kent Kresa, chairman and chief executive officer of Northrop Grumman, stated: "We have not received a substantive response from TRW regarding our February 21 letter to enter into negotiations for a proposed business combination. We continue to believe that such a transaction would be in the best interests of both companies' shareholders. Accordingly, we are moving ahead to make this offer available to TRW shareholders and to initiate all the steps that are necessary to see it through to conclusion, including requesting that the TRW board of directors call the special meeting of shareholders required under Ohio law to authorize our acquisition of TRW shares. We expect that the TRW shareholders will respond favorably. In addition, we are filing a lawsuit in Ohio challenging elements of its anti-takeover laws."

Mr. Kresa added, "As we stated on February 22, the proposed strategic combination of Northrop Grumman and TRW will create a third major contributor to the nation's satellite and missile defense requirements. Following completion of the acquisition, we intend to promptly separate TRW's automotive business from the rest of the combined company either through a sale to a third party or parties or a spin off to the shareholders of the combined companies," Kresa added.

Mr. Kresa noted that Northrop Grumman remains willing to entertain negotiations with TRW regarding a transaction and would welcome the opportunity to consider non-public information about TRW in order to consider any enhanced values that might be demonstrated by such information.

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.
