Northrop Grumman
Corporation today announced the appointments of two presidents to
lead two new operating sectors created from the company’s acquisition of TRW,
Inc.

Donald C. Winter, 54, has been named a corporate vice president and
president of the Northrop Grumman Mission Systems sector, formerly TRW
Systems, where he served as president and chief executive officer. Northrop
Grumman Mission Systems, with expected 2003 revenues of $3.9 billion, employs
approximately 16,000 people and is headquartered in Reston, Va.

Timothy W. Hannemann, 59, has announced his intention to retire as
president of the Northrop Grumman Space Technology sector, formerly TRW Space
and Electronics, on Jan. 31, 2003. Effective Feb. 1, 2003, Wesley G. Bush,
41, will become corporate vice president and president of Northrop Grumman
Space Technology. The sector, headquartered in Redondo Beach, Calif., has
2003 estimated revenues of $2.5 billion and employs approximately 8,600
employees.

“We are pleased to have such highly qualified executives to lead our two
new operating sectors,” said Kent Kresa, Northrop Grumman chairman and chief
executive officer. “These two operating sectors join us with tremendous
momentum, having won several large contracts in the past few months.”

Commenting on Tim Hannemann, Northrop Grumman President and Chief
Operating Officer Ronald D. Sugar said, “Over the past 33 years Tim has made
remarkable contributions to TRW and is a recognized leader in the national
security and civilian space industry. He has superbly positioned TRW’s space
and electronics business for continued growth and prosperity. We wish Tim
well in his much-deserved retirement.”

Sugar continued, “As a longtime colleague of both Don and Wes, I know
firsthand of their outstanding capabilities. Don’s proven leadership, strong
technical background and excellent relationships with his customers will help
our new Mission Systems sector continue to produce strong results.”

Winter has served as president and CEO of TRW Systems since January 2000.
A 28-year company veteran, Winter has also held senior systems engineering and
program management positions for a variety of space system programs.

“Wes Bush has extensive management experience across a broad spectrum of
the space business which makes him well qualified to lead our Space Technology
sector as it begins work on some of its largest and most important new
programs,” Sugar added.

Bush most recently served as president and CEO of TRW Aeronautical Systems
prior to its October 2002 sale to Goodrich Corporation. Previously, Bush
spent 15 years at TRW Space & Electronics, where he had broad technology and
operational experience in a series of management positions, leading to a vice
president and deputy assignment. He also served as vice president and general
manager of TRW’s Telecommunications Programs Division, where he was
responsible for developing and producing advanced satellite and terrestrial
wireless communications.

Winter earned a Bachelor of Science degree (with highest distinction) in
physics from the University of Rochester. He received a Master of Science
degree and a doctorate in physics from the University of Michigan.

Bush earned both bachelor’s and master’s degrees in electrical engineering
from the Massachusetts Institute of Technology, and he is a graduate of the
UCLA Anderson School Executive Management Program.
