Northrop Grumman
Remarks for TRW Annual Meeting
April 24, 2002
4/23/2002 10:04 PM

Let me begin by making clear our long-standing high regard for TRW, its
management team and its employees. For years we have admired the tremendous
technologies and capabilities produced by TRW's world-class operation. In fact,
as we have publicly stated, Northrop Grumman has been talking with TRW's
management team for several years about a possible business combination.

As you know, we made a proposal on February 21 to enter into discussions
regarding the strategic combination of our two fine companies. Yet, so far, TRW
has been unwilling to negotiate with us. As a result, we are here today to
present TRW shareholders with three Northrop Grumman proposals. These proposals
are designed to enable you--the owners of TRW--to express your wishes with
regard to TRW's entering into negotiations with Northrop Grumman.

As I previously mentioned, we have a great deal of respect for TRW, and this is
a primary reason we remain so interested in a combination of our


businesses. Let me briefly highlight a few reasons why we think a combination
makes such good strategic sense. Together, TRW and Northrop Grumman would create
a third major player in the growing military space business, providing our
country with enhanced competition and innovation in areas key to national
defense. TRW would also add complementary capabilities in communications,
electronics and information warfare, while broadening Northrop Grumman's
information technology customer base. In fact, together we would create the
nation's largest supplier of information technology services to the federal
government. So, we think a combination of our two companies would be in the
long-term interest of TRW shareholders as well as Northrop Grumman shareholders.

Let me remind everyone of Northrop Grumman's excellent acquisition track record.
Since 1994, we have acquired and successfully integrated some 15 companies.
Employees who have come to Northrop Grumman through acquisitions have thrived,
and their businesses have grown through the strength created by the combination
of related operations. Northrop Grumman has demonstrated its respect for unique
cultures of the companies it acquires--a respect that we believe contributes to
the ongoing success of the combined organization.


Our offer is to acquire the outstanding shares of TRW in a tax free exchange.
Our plan, a variation of which TRW has lately adopted, we believe on a riskier
basis, is to sell the automotive business or spin it to the shareholders on a
tax advantaged basis. We will initially operate TRW's remaining businesses as a
new separate sector within Northrop Grumman.

Should a combination of TRW and Northrop Grumman become a reality, TRW employees
in the defense, IT and aerospace businesses would become part of our combined
organization and, we believe the opportunities afforded to them by the
combination would be tremendous. At the same time, we believe our plan offers
those employees in TRW's strong automotive sector many benefits as well, by
providing for a more rapid alignment with your industry. You will be a major,
stand-alone automotive supplier--one that's able to compete and thrive on its
own, and one that's positioned to create value for its shareholders.

As Northrop Grumman's business has grown, so have the investment returns for
Northrop Grumman shareholders. Between 1999 and 2001, for example,


Northrop Grumman's stock has nearly doubled, while an investment in TRW shares
declined by 25 percent during that same period.

One way or another...with or without Northrop Grumman...TRW is about to undergo
change. As a shareholder...and/or an are in a position to have a
say in what that change will be.

Northrop Grumman seeks a negotiated transaction with TRW. However, this is not
possible unless we are able to conduct an effective due diligence. So far, TRW
has been unwilling to allow us to begin this necessary process and we were
surprised by the nature of the standstill provisions suggested in their
confidentiality agreement. Based on available data, we believe that our $53
offer in Northrop Grumman common stock represents full and fair value. We need
to conduct due diligence. We are pleased that, in reaction to our proposal, TRW
has decided to explore strategic alternatives. And we are hopeful that they will
follow through on their commitment to you to allow due diligence to proceed.
Once this process has taken place, we will reach a conclusion as to the true
value of your company and, if our due diligence supports greater value, as we
have said many times, we are willing to pay a higher price. But at the end of
the process it isn't what we believe that


counts. It is the shareholders who will have the final say. A negotiated
transaction between TRW and Northrop Grumman will provide shareholders their
best value and without their support, there will be no transaction.

Your company states that there is hidden value within TRW that we should
recognize in our price. Show us that hidden value.

We look forward to the opportunity to quickly enter into substantive discussions
that could lead to a negotiated transaction that would be in the best of
interests of TRW shareholders. We have been requesting this since late February,
and I repeat that request now to you, the shareholders.

We believe our plan offers a more certain outcome, greater value and far lower
risk than the restructuring plan TRW's board has proposed. TRW's plan, in our
view, offers no certain value, no clear timetable to completion and entails far
more risk than our offer. Again, I urge TRW shareholders to examine our track
record. We know how to acquire and integrate businesses to create shareholder
value. Since we are offering stock, TRW shareholders will not only get the
premium of our offer, but will also share in value created for Northrop Grumman


We are asking TRW shareholders to vote for three proposals:

     .    The first proposal requests TRW's directors to provide Northrop
          Grumman with non-public information.

     .    The second requests TRW's directors establish a committee of
          independent directors to evaluate our acquisition proposal and any
          other proposals received by the company.

     .    The third proposal we are asking TRW shareholders to vote FOR is a
          proposal requesting TRW's directors to take all actions within their
          authority to provide TRW shareholders the opportunity to decide for
          themselves whether to exchange their TRW shares for Northrop Grumman
          common stock.

We urge TRW shareholders to vote FOR our three annual meeting proposals, which
will pave the way for a negotiated transaction between the two companies.

On behalf of the Northrop Grumman board of directors and the senior management
team, we appreciate your thoughtful consideration of our proposals. We sincerely
hope to conclude a transaction beneficial to the


shareholders of both companies in the near future and are appreciative of your
support towards this end. Thank you.
