US UNWIRED INC. ANNOUNCES CLOSING OF SENIOR SECURED NOTES OFFERING

Lake Charles, LA (June 16, 2004)—US Unwired Inc. (OTC Bulletin Board:UNWR) stated today that it closed its previously announced offering of $360 million of senior secured notes, consisting of $125 million aggregate principal amount of first priority senior secured floating rate notes due 2010 (“2010 Notes”) and $235 million aggregate principal amount of 10% second priority senior secured notes due 2012 (“2012 Notes”). In addition, US Unwired announced that it paid in full and terminated its existing senior secured credit facility and purchased $235.8 million face amount of its outstanding 13 3/8% Senior Subordinated Discount Notes due 2009.

“We are extremely pleased with our recent financing activities. In patiently waiting for market dynamics to converge with our improving operating results, we solidified our balance sheet and improved our overall financial flexibility,” said Robert Piper, US Unwired’s Chief Executive Officer.

“In particular, we accomplished three critical objectives: First, and most importantly, we de-levered while minimizing shareholder dilution. Through a series of strategic debt-for-equity exchanges, we eliminated $75 million face amount of senior subordinated discount notes. Second, we lowered our overall cost of debt. Our new capital structure optimizes the collateral in our balance sheet for debt holders, reducing our all-in interest rate by approximately 300 basis points. Finally, we positioned the company’s balance sheet for further improvement. We transformed high investor demand for our new securities into $75 million cash that will allow us to call our high-cost bonds beginning in November 2004.”

The following table sets forth US Unwired’s cash and capitalization as of March 31, 2004 on: (i) an actual basis for US Unwired, excluding the operations of IWO and (ii) an as adjusted basis to give effect to the previously announced 3(a)(9) exchanges and the completion of the above described note offerings:
