Business Editors

REDMOND, WA--(BUSINESS WIRE)--June 7, 2001

AT&T Wireless (NYSE: AWE) today announced that Andre Dahan has been named president and chief executive officer of its new Mobile Multimedia Services subsidiary. As announced last November, AT&T Wireless and NTT DoCoMo are working together to develop the next generation of advanced multimedia services.

The AT&T Wireless wholly-owned subsidiary is developing leading-edge multimedia applications for its current digital network as well as for a new, high-speed wireless network built to global standards for "third generation" (3G) services such as graphic presentation of data, video email, high quality music downloads, and streaming audio and video. Both companies are sharing technical resources and support staffing for the new subsidiary, which is based in Redmond, Washington.

Dahan will begin his new position on July 2 and have responsibility for leading all aspects of the business including research and development, operations, finance, sales and marketing. Most recently, Dahan held several senior executive positions with The Dun & Bradstreet Corporation - the world's leading provider of business-to-business credit, marketing and purchasing information. He was president of Dun & Bradstreet North America, senior vice president and head of electronic commerce, and president and founder of eccelerate.com, a Dun & Bradstreet e-commerce venture based in Silicon Valley.

"We're extremely proud to have Andre join our team. He's a creative, seasoned and visionary leader," said John D. Zeglis, chairman and chief executive officer, AT&T Wireless Group. "With today's profound and evolving linkages between wireless, the Internet, consumer electronics, and other advanced information technology, we sought a leader whose experience transcended the conventional knowledge of all of these disciplines, and Andre is that person. Under Andre's guidance, we will lead the way in ushering-in the next generation of advanced wireless services and applications throughout North America. We have the right partners, technology, know-how, and now with Andre, the right leader."

Dahan has more than 28 years of leadership experience in the information technology sector. He began his career as a database architect with the Israeli government and held a variety of technical positions with IBM and S.E. Qual, an information technology-consulting firm. Dahan later served as vice president of sales and marketing at Teradata. In 1991, Teradata was acquired by AT&T Global Information Solutions (now NCR) and Dahan served as vice president of worldwide marketing. Prior to joining Dun & Bradstreet in 1997, Dahan served as senior vice president of worldwide operations for Sequent Computer Systems in Portland, Oregon.

Dahan earned a bachelor's degree in computer science from the Jerusalem Institute of Technology.
