REDMOND, Wash.--(BUSINESS WIRE)--March 10, 2003

AT&T Wireless (NYSE:AWE) and U.S. Cellular Corporation (AMEX:USM) today announced the signing of a definitive agreement to swap wireless licenses and properties covering 15 states and more than 18 million people.

Under terms of the agreement AT&T Wireless would receive U.S. Cellular's wireless operations and assets in northern Florida and southern Georgia including Tallahassee and Gainesville, Florida. The markets serve 141,000 customers and reach a population of more than 1.5 million people. The acquisition of these markets fills in a key gap in AT&T Wireless' nationwide network and expands the company's network to virtually all major cities and travel routes in both states.

U.S. Cellular would acquire wireless licenses in 13 states in the Midwest and Northeast covering 16.6 million people and cash. The licenses are surplus to AT&T Wireless and will not have an effect on the company's customers or operations.

"We're pleased to offer our national voice and data services to these newly acquired markets," said Emilio Echave, regional vice president, south region. "AT&T Wireless is working every day to expand and improve our wireless network. This acquisition is a key enhancement in what is already one of the most advanced systems in the U.S."

The agreement is subject to customary regulatory approvals and has been approved by the boards of both companies. Closing is expected in the second half of 2003.
