Each of the new appointees will stand for election at ADC's annual meeting currently planned for March 1, 2005. These new appointees increase the board to 14 members, which is a temporary increase in the total number of directors in order to facilitate a smooth transition in connection with the planned retirement of certain directors over the next two to three years.

Gilligan is a seasoned operating executive, most recently serving as the president and CEO of the automation and control solutions business at Honeywell International where he had a distinguished career spanning over 25 years. He is known for leading change and repositioning businesses for profitable growth combined with a strong track record in negotiating and integrating successful acquisitions. Gilligan graduated from Boston College with a bachelor of science degree in economics and political science.

Rehfeld is a visionary, marketing-driven CEO and outside board member with 30 years of technology experience, especially in international strategic relationships with the senior management of Asian companies, including Toshiba and Seiko. He holds a master of business administration from Harvard University.

Spivey is an accomplished and dedicated senior executive with 30 years of managerial experience in high-volume, high-technology businesses, including Luminent, Lucent Technologies, AT&T Corporation, Tektronix, Honeywell, and General Electric.

"I am confident that Kevin, John and Bill will complement the board of directors with valuable experience and knowledge," said Bob Switz, president and CEO of ADC.
