Acquisition Creates $15 Billion Top-Tier Global Defense Enterprise

     LOS ANGELES -- April 3, 2001 -- Northrop Grumman Corporation (NYSE: NOC)
announced today that it has completed the purchase of all tendered shares of
Litton Industries Inc. common and Series B preferred stock, after receiving all
required U.S. and international governmental and regulatory approvals.

     "Today marks an exciting new chapter in Northrop Grumman's 60-year
history," said Kent Kresa, Northrop Grumman's chairman, president and chief
executive officer.  "The Litton acquisition creates a $15 billion, top-tier
global defense enterprise with 80,000 employees worldwide.  Without question,
the global military environment has changed.  So, too, has Northrop Grumman,"
Mr. Kresa added.  "With Litton, we have solidified our position in major growth
segments of the 21st century defense marketplace."

     Mr. Kresa said Litton is a superb strategic fit that offers tremendous
synergies with existing Northrop Grumman businesses.  "Together, we form an
extraordinary team of men and women who share a proud history of achievement and
the promise of future accomplishments," he noted.

     "Litton elevates Northrop Grumman to a defense electronics powerhouse and
one of the largest providers of information technology for the federal
government," Mr. Kresa said.  "It also gives us the new prime capability of
shipbuilding, making us the largest supplier of non-nuclear surface ships for
the U.S. Navy.  Litton also adds world-class capabilities in the commercial
electronics arena."


                                                                          Page 2

     Northrop Grumman said with continued strong growth from existing businesses
and the Litton acquisition, the company's revenues are expected to double to $15
billion in 2001 and to $18 billion in 2003.  The company also expects double-
digit increases in its economic earnings (excluding pension income, amortization
of goodwill and other purchased intangibles) through 2003.

     Mr. Kresa said he was particularly pleased that Northrop Grumman closed the
transaction a few days after the end of the first quarter, meeting the goal set
when the acquisition was announced on Dec. 21, 2000.  The integration of
Litton's businesses into Northrop Grumman will begin immediately and should be
completed by the end of this year.

     The company received early termination notice for the acquisition on March
30, 2001, from the Federal Trade Commission under the Hart-Scott-Rodino Act.
Previously, the European Commission approved the transaction on March 23, 2001.
The tender offer for Litton's common and preferred stock expired April 2, 2001,
at midnight E.D.T.

     To welcome Litton employees to Northrop Grumman, Mr. Kresa is touring
Litton's facilities, beginning today in Pascagoula, Miss., home of the Ingalls
shipyard.  On the trip, he will also visit the Avondale shipyard in New Orleans,
La.; meet with employees of PRC and TASC in the Washington, D.C., area; address
employees of Interconnect Technologies in Springfield, Mo.; and welcome
employees of three defense electronics divisions based in the Los Angeles area.

     Under a definitive agreement signed by the two companies, the value of the
Litton acquisition is approximately $5.1 billion, which includes the assumption
of Litton's $1.3 billion in net debt.

     Northrop Grumman has been advised by the depository, Equiserve Trust Co.,
NA, that as of midnight E.D.T. on April 2, 2001, in excess of 90 percent of the
outstanding shares of Litton Industries common stock and in excess of 50 percent
of the shares of Series B preferred stock had been validly tendered, including
tender by guarantees of delivery.

     The company said it will move promptly to complete the acquisition of the
remaining shares of Litton's common stock pursuant to the merger agreement
signed Jan. 23, 2001.


                                                                          Page 3

Following the acquisition, those shares of Litton not tendered under the tender
offer will be converted into the right to receive $80 per share in cash.
Litton's Series B preferred shares will not be affected in the merger.
