BETHESDA, MD, 09-MAY-01 -- Lockheed Martin Corporation (NYSE: LMT) today announced the retirement of Philip J. Duke, 55, head of the Corporation's Shared Services organization. He is succeeded by Marillyn Hewson, currently vice president, Global Supply Chain Management. Phil's 22 years of dedicated service have been instrumental in helping to shape Lockheed Martin's growth and success, said Lockheed Martin Chairman and Chief Executive Officer Vance D. Coffman. We greatly appreciate his many years of service to Lockheed Martin and his active participation on the leadership team. We wish him well in his retirement.

Coffman also praised Duke's successor noting that Hewson brings a wealth of experience to her new position as vice president, Shared Services. Marillyn's broad leadership experience in procurement and financial control will bring valuable contributions to Lockheed Martin's effort to reduce costs and improve productivity through our Shared Services concept, Coffman said.

As vice president, Global Supply Chain Management since August 2000, Hewson, 47, has been responsible for the Corporation's procurement activities, including E-commerce, commodity procurement, and subcontract management. In this position, she significantly reduced the Corporation's costs by leveraging the volume of the Corporation's purchases and exploiting advances in electronic procurement.

Previously, she served as vice president, Internal Audit. She joined Lockheed Martin in 1983 as an industrial engineer at the Corporation's Marietta, Georgia, facility, progressing through increasingly responsible operations management positions.

A native of Kansas, Hewson earned a bachelor's degree in Commerce and Business Administration, and a master's degree in Economics from the University of Alabama. She resides in Potomac, Maryland, with her husband, James, and two sons.
