TRW Board Determines Northrop Grumman's $47 Exchange Offer Is Financially

Recommends TRW Shareholders Reject the Northrop Grumman Offer
Announces Strategic Plan to Enhance Shareholder Value
Special Meeting of Shareholders Set For April 22, 2002

CLEVELAND, March 13 /PRNewswire-FirstCall/ -- TRW Inc. (NYSE: TRW) announced
today that after careful consideration, including a thorough review with
independent financial and legal advisors, its board of directors has unanimously
determined that Northrop Grumman Corporation's (NYSE: NOC) March 4, 2002
unsolicited exchange offer for all outstanding shares of TRW common stock for
$47 per share is financially inadequate and not in the best interests of TRW's
shareholders. Accordingly, the TRW board of directors urges TRW shareholders to
reject Northrop Grumman's offer and not exchange their shares.

    "As we indicated when we rejected Northrop Grumman's earlier proposal, this
is all about shareholder value," said Philip A. Odeen, TRW's chairman.

    In making its recommendation, TRW's board of directors considered, among
other things, that:

    * Northrop Grumman's offer grossly undervalues TRW's businesses and

    * The opinion of each of its independent financial advisors, Goldman, Sachs
      & Co. and Credit Suisse First Boston, that Northrop Grumman's offer is
      inadequate to the company's common shareholders from a financial point of

    * Northrop Grumman's offer price remains below the current market price of
      TRW's common stock. As of March 12, 2002, TRW's closing stock price was
      $50.28 per share.

    * Northrop Grumman's offer is highly conditional, which results in
      significant uncertainty that the offer will be consummated.

    "Our board of directors continues to believe that $47 is grossly inadequate
and does not reflect the value of TRW's advanced portfolio of

technology and unique market leading positions. Further, since this offer is
subject to a collar which could result in a price of less than $47 per share,
this offer is less favorable than Northrop Grumman's earlier proposal," said Mr.

    The board noted that Northrop Grumman made its offer at a time when TRW's
stock price was temporarily depressed following the unexpected resignation of
David Cote, TRW's former chairman, president and chief executive officer.

    "Northrop Grumman's offer is clearly an opportunistic attempt to acquire
TRW's premier franchise. In particular, the current planned increases in
government defense spending are expected to benefit many technologies and arenas
where TRW's space, electronics and systems businesses are a leader.
Additionally, we believe that our automotive and commercial aerospace businesses
will benefit from positive economic trends in these sectors," continued Mr.

    TRW's Value Enhancing Strategic Plan

    TRW's board of directors believes that the company can significantly enhance
value for TRW shareholders through the continued execution of its strategic
plan. As part of this plan, TRW intends to accelerate its debt reduction program
and separate its Automotive business in a tax-efficient manner. Key elements of
the plan include:

    * Acceleration of TRW's deleveraging initiatives through asset sales and
      other alternatives. In 2001, the company reduced its net debt by almost $1
      billion and, over the past three years, it has reduced net debt by
      approximately $3.9 billion. The company is targeting an additional $1.6
      billion to $2.0 billion debt reduction in 2002.

    * Exploration of additional actions, including the spin-off of TRW's
      Automotive business. As planned, the Automotive business would become an
      appropriately capitalized, independent, publicly traded company. TRW has
      targeted completion of the spin-off of the Automotive business in
      approximately six to nine months.

    "TRW has been examining a potential separation of our Automotive business
for some time," added Mr. Odeen.  "We believe that our strategic plan
announced today will create two `pure play' independent businesses, each

positioned to deliver superior growth and returns. Additionally, this plan will
enable each company to optimize strategic and financial flexibility and capture
value against best-in-class industry benchmarks. We believe our strategic plan
will deliver greater value to TRW shareholders than Northrop Grumman's offer."

    Since the announcement of Northrop Grumman's proposal on February 22, 2002,
TRW and its independent financial advisors have received unsolicited indications
of interest from third parties with respect to a transaction with the company as
a whole which would involve a separation of the Automotive business. In
addition, the company has received unsolicited indications of interest from
third parties with respect to each of its operating businesses as well as a
private equity investment in the entire company. Also, TRW is engaged in
preliminary discussions with third parties concerning transactions involving all
or a portion of the Automotive business, and the company has commenced
preliminary negotiations for a potential sale of its Aeronautical Systems Group.

    TRW Is Well Positioned To Capitalize On The Positive Economic Trends
     Across Auto, Defense and Aerospace Businesses

    * Given positive recent economic trends, industry analysts have raised their
      forecast for 2002 North American automotive light vehicle production from
      between 15.0 million and 15.3 million vehicles to between 15.7 million and
      15.9 million units. TRW holds the number one or two market positions in
      the worldwide supply of key automotive products, including seat belts, air
      bags, antilock brakes (North America) and steering gears, and is well
      positioned to capitalize on this market growth.

    * The United States defense budget is projected to have a 7.2% compound
      annual growth rate through 2006, and TRW's space and defense businesses
      are in the "sweet spot" of this growth. TRW's capabilities in space,
      defense and communications are aligned with the U.S. Defense Department's
      focus on information superiority, missile defense, battlefield superiority
      and homeland security.

    * According to a recent report from a leading trade organization for

      airlines in the United States, the commercial aerospace sector appears to
      have stabilized. TRW believes this will enhance its spares and
      maintenance, repair and overhaul businesses.

    TRW Is On Track To Deliver Sustainable Earnings And Cash Flow Growth

    The board and senior management of TRW are committed to continuing to focus
on the company's aggressive cost cutting initiatives, productivity improvements
and enhancing relationships with its customers. The company is on track to meet
or exceed its 2002 commitments.

    The company affirmed that the board's executive search committee, comprised
of outside directors, has selected a prominent executive search firm and is
actively engaged in a search for a new chief executive officer.

    Special Meeting of Shareholders Set

    TRW also announced today that its board of directors has called a Special
Meeting of TRW shareholders for Monday, April 22, 2002 for the purpose of voting
under Ohio law on Northrop Grumman's proposed control share acquisition.
Shareholders of record on the close of business on March 28, 2002 will be
eligible to vote at the special meeting.

    TRW noted that it expects to furnish shareholders with a notice of meeting
and related proxy statement later this month.

serving as financial advisors to TRW, and Skadden, Arps, Slate, Meagher & Flom
LLP is serving as legal counsel.

    TRW provides advanced-technology products and services for the aerospace,
