U.S. Cellular will acquire 10 and 20 MHz PCS licenses in 13 states, representing 12.2 million incremental population equivalents contiguous to existing properties and 4.4 million population equivalents that overlap existing properties. Markets U.S. Cellular will acquire in the transaction include Oklahoma City, Okla., St. Louis and Springfield, Mo., Indianapolis, Ind., Burlington, Vt. and Portland, Maine. U.S. Cellular will not acquire any customers or network. A complete list of all the properties U.S. Cellular will acquire can be found in Exhibit A.

U.S. Cellular will also acquire AT&T Wireless minority interests in six U.S. Cellular-controlled markets. Additionally, U.S. Cellular will receive approximately $31 million in cash.

AT&T Wireless will receive U.S. Cellular wireless assets in 10 markets in Florida and Georgia. The assets will include 25MHz A block cellular licenses and the network, customers and associated assets of those markets. The licenses to be transferred to AT&T Wireless represent 1.5 million population equivalents and include approximately 141,000 customers. For 2002, total revenue from these markets was $107 million and operating income excluding certain shared services costs was $25 million. The transaction is subject to regulatory approvals and is expected to close in the third quarter of this year.

John E. Rooney, president and chief executive officer, commented: “We are very excited about this transaction and the growth opportunity it provides. It gives us the opportunity to substantially improve our competitive position in our Midwest and Northeast markets. We will now be in a position to offer more competitive local and regional calling plans encompassing broader areas than we have been able to do in the past.

“Today’s announcement is a clear manifestation of our corporate strategy. We have said for some time that we need to strengthen our regional footprint through purchase or trade, building on our strengths and exiting other markets. This transaction does just that!" Rooney added.

Falkenberg Capital Corporation of Denver, Colo. represented U.S. Cellular in the transaction.
