• $7.8 Billion Transaction Positions Northrop Grumman As Nation’s Second Largest Defense Contractor
  • Adds Significant Strengths in Satellite Systems, Missile Defense and Systems Integration Capabilities
  • TRW’s Board Achieves Goal of Enhancing Shareholder Value
  • Northrop Grumman Confirms 2002 Financial Guidance; Says It Will Achieve Double-Digit Growth for 2003; and Projects Double-Digit Growth for 2004
  • 2003 Sales Expected to Be $26 to $27 Billion

Grumman Corporation (NYSE: NOC) and TRW Inc. (NYSE: TRW) jointly announced
that they have entered into a definitive merger agreement. The combination
will position Northrop Grumman as the nation’s second largest defense
contractor with projected annual revenues of more than $26 billion and
approximately 123,000 employees. Following the separation of TRW’s automotive
business and completion of the sale of TRW’s Aeronautical Systems business,
Northrop Grumman will be a Fortune 100 company.

Under the terms of the agreement, unanimously approved by the boards of
directors of both companies, Northrop Grumman will acquire TRW for $60 per
share in common stock in a transaction valued at approximately $7.8 billion,
plus the assumption of TRW’s net debt at the time of closing.

The exact exchange ratio will be determined by dividing $60 by the average
of the reported closing sale prices per share of Northrop Grumman common stock
on the New York Stock Exchange for the five consecutive trading days ending on
and including the second trading day prior to the closing of the merger. The
exchange ratio will not be less than 0.4348 or more than 0.5357 of a Northrop
Grumman share.

After completion of the merger, Northrop Grumman plans to separate TRW’s
automotive business, either through a sale or a spin-off of the business to
shareholders. TRW’s previously announced agreement to sell its Aeronautical
Systems business to Goodrich Corporation for $1.5 billion will remain
unaffected by today’s announcement.

Kent Kresa, chairman and chief executive officer of Northrop Grumman,
said, “Today is a great day for Northrop Grumman and TRW. We’re bringing
together the superior technology and outstanding talent of two of our nation’s
premier defense companies, creating a powerful and highly competitive
enterprise with excellent growth prospects. Today’s acquisition adds the last
critical node of space to our robust and well-diversified defense platform and
systems capabilities that operate on the ground, at sea and in the air. We
believe this transaction provides tremendous value to our shareholders,
employees and customers.

“When we first proposed to acquire TRW, we stated that we were prepared to
pay full and fair value for the company, subject to a comprehensive due
diligence process. Our thorough due diligence made clear to us the strength
and value of TRW’s operations and the tremendous opportunities for the
combined defense enterprise,” said Kresa.

“The talents and creative energies of TRW’s defense industry employees are
among the company’s greatest strengths and we look forward to welcoming them
to the Northrop Grumman family. Following the completion of the transaction,
we will seamlessly transition the defense businesses into the company as was
done recently with Litton and Newport News,” concluded Kresa.

Philip A. Odeen, chairman of TRW, said, “This is a real win for TRW
shareholders. For the past several months, TRW’s board has undertaken a
comprehensive strategic review with the sole objective of enhancing
shareholder value. This transaction achieves that objective. We have said
from the start that this was all about shareholder value and this transaction
delivers to our shareholders full value from their TRW investment. In
addition to receiving a premium on their investment, TRW shareholders also
have the opportunity to participate in the upside potential created by the
combination of these two great businesses. Together, our companies will
create a true industry powerhouse with an unparalleled portfolio of premier
technologies, expertise and capabilities.”

Northrop Grumman Confirms 2002 Guidance; Provides 2003 Guidance

In addition to confirming 2002 economic earnings per share guidance of
$6.60 to $7.10, Northrop Grumman said that with the acquisition of TRW, the
company expects 2003 economic earnings to be in the range of $7.75 to
$8.30 per share and GAAP earnings of $6.00 to $6.55 per share, with
double-digit growth again expected in both economic and GAAP earnings in 2004.
Prior to the B-2 related tax payment, the company expects cash from operations
in 2003 to be approximately $1.25 billion, and to average well over $2 billion
per year for the next several years thereafter. Including the effects of this
transaction and the company’s B-2 program tax payment, Northrop Grumman
expects to have a debt to capitalization ratio at year-end 2003 near or below
the low end of its 30 percent to 40 percent target range.

Following the close of the transaction, TRW’s defense business, similar to
the Litton and Newport News businesses, will be initially operated as a
separate Northrop Grumman sector, reporting to the office of the chairman.
Northrop Grumman will work to quickly integrate the operations of TRW’s
defense business operations. Northrop Grumman foresees little change in
employment levels in the defense business as a result of this transaction.

The transaction is subject to the approval of shareholders of both
companies and to review under the Hart-Scott-Rodino Act as well as other
governmental and regulatory agencies in the U.S. and Europe. The companies
expect to complete the transaction in the fourth quarter of 2002.

As a result of the definitive merger agreement, Northrop Grumman did not
extend its exchange offer for all outstanding shares of common and preferred
stock of TRW Inc., which expired at midnight EDT on Friday June 28, 2002, and
will not accept any shares tendered. Northrop Grumman expects to amend its
current Form S-4 registration statement shortly.

Salomon Smith Barney and Stephens Financial Group acted as financial
advisors to Northrop Grumman. Goldman, Sachs & Co and Credit Suisse First
Boston advised TRW.

operations are subject to various additional risks and uncertainties resulting
from its position as a supplier, either directly or as subcontractor or team
member, to the U.S. Government and its agencies as well as to foreign
governments and agencies; actual outcomes are dependent upon factors,
including, without limitation, Northrop Grumman’s successful performance of
internal plans; government customers’ budgetary restraints; customer changes
in short-range and long-range plans; domestic and international competition in
both the defense and commercial areas; product performance; continued
development and acceptance of new products; performance issues with key

Note: With respect to TRW: This press release contains certain
“forward-looking statements” that TRW believes are within the meaning of the
Private Securities Litigation Reform Act of 1995. However, TRW shareholders
should be aware that the preparation of any forward-looking statements
requires the use of estimates of future revenues, expenses, activity levels
and economic and market conditions, many of which are outside of TRW’s
control. Further, TRW’s results could be affected by the ability to obtain
new contract awards; the level of defense funding by the government and
determination of existing government contracts; pricing pressures from
customers; moderation or decline in the automobile build rate; changes in
consumers debt levels; work stoppages; unanticipated downturn in the financial
condition of, or business relationships with customers and suppliers; the
ability to reduce the level of outstanding debt from cash flow from operations
and the proceeds from asset dispositions; a credit rating downgrade; increase
in interest rates; customer recall and warranty claims; product liability and
litigation issues; changes to the regulatory environment regarding automotive
safety; the introduction of competing products or technology by competitors;
the ability to attract and retain skilled employees with high-level technical
competencies; the financial results of companies in which we have made
technology investments; the ability of funding for research and development;
economic, regulatory and political domestic and international conditions;
fluctuations in currency exchange rates; and the impact of additional
terrorist attacks, which could result in reduced automotive production,
disruptions to the transportation system, or significant and prolonged
disruption to air travel. In addition, there can be no assurance: regarding
the completion of the merger, the receipt of necessary government approvals,
or the completion of the sale of the aeronautical systems business. Other
factors and assumptions not identified above are also involved in the
preparation of forward-looking statements, and the failure of such factors and
assumptions to be realized may also cause actual results to differ materially
from those discussed. TRW assumes no obligation to update such estimates to
reflect actual results, changes in assumptions or changes in other factors
affecting such estimates other than as required by law.

The directors and certain executive officers of TRW may be deemed to be
participants in the solicitation of proxies from shareholders of TRW in
connection with TRW’s special meeting of shareholders to consider the
Agreement and Plan of Merger, dated as of June 30, 2002, with Northrop
Grumman. Information concerning such participants will be contained in a
Form 8-K to be filed by TRW with the Securities and Exchange Commission.
