FOR RELEASE: IMMEDIATE

TDS AND U.S. CELLULAR RECEIVE FURTHER EXTENSIONS FROM AMEX AND LENDERS
Companies require additional time to complete restatement of prior period results

CHICAGO - Feb. 12, 2007 - Telephone and Data Systems, Inc. [AMEX:TDS, TDS.S] and United States Cellular Corporation [AMEX:USM] today announced that the American Stock Exchange (AMEX) granted both companies an extension until March 14, 2007 to regain compliance with AMEX listing standards resulting from delayed filing with the Securities and Exchange Commission (SEC) of their Forms 10-Q for the quarter ended Sept. 30, 2006. Previously, the AMEX had notified both companies that it had accepted their plans to regain compliance and had granted both companies an extension until Feb. 12, 2007 to make these delayed filings. TDS and U.S. Cellular continue to be noncompliant with the listing standards of the AMEX and their listing is being continued pursuant to the additional extension of time to March 14, 2007 to regain compliance.

TDS and U.S. Cellular require additional time to complete the restatement of prior period results announced on Nov. 6, 2006. As a result, the companies may not be able to complete and file their Forms 10-K for the year ended Dec. 31, 2006 and their Forms 10-Q for the quarter ended March 31, 2007 on time. TDS and U.S. Cellular are working diligently to complete and file these additional forms accurately and as timely as possible. If necessary, TDS and U.S. Cellular will seek extensions from the AMEX for filing their Forms 10-K for the year ended Dec. 31, 2006 and their Forms 10-Q for the quarter ended March 31, 2007 after these documents are considered late.

In addition, both companies have received extended waivers from their lenders under credit agreements and from counterparties under certain forward contracts provided that that they file their Forms 10-Q for the quarter ended Sept. 30, 2006 by March 14, 2007, their Forms 10-K for the year ended Dec. 31, 2006 within 60 days of filing the Forms 10-Q for the quarter ended Sept. 30, 2006, and their Forms 10-Q for the quarter ended March 31, 2007 within 45 days of filing the 2006 Forms 10-K. Waivers of defaults were previously extended, on the condition that the companies file their Forms 10-Q for the quarter ended Sept. 30, 2006 on or before the extended due date of Feb.12, 2007.

On Nov. 6, 2006, the companies announced that they would restate financial results for each of the years ended Dec. 31, 2002 - 2005, quarterly information for 2004 and 2005, and the first and second quarters of 2006. The restatement was required primarily to correct the accounting for prepaid forward contracts under Statement of Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities. The companies have also included adjustments in the restatement for items representing out-of-period adjustments and corrections of errors, some of which were identified during 2006.
