Item 1.01 Entry into a Material Definitive Agreement.

On June 23, 2008, USEC Inc.’s ("USEC" or the "Company") wholly owned subsidiary, United States Enrichment Corporation, exercised its exclusive option to renew the lease agreement dated as of July 1, 1993 between the United States Department of Energy ("DOE") and United States Enrichment Corporation (the "Lease"), with respect to the Paducah gaseous diffusion plant located in Paducah, Kentucky and Portsmouth gaseous diffusion plant located in Piketon, Ohio, which are owned by the U.S. government. USEC elected to renew the Lease until June 30, 2016. Under the terms of the Lease, the renewal option must be exercised at least two years prior to the expiration of the current lease term (which was scheduled to expire on June 30, 2010) and the Lease may be renewed for successive periods of between one and six years in length. Notwithstanding the renewal of the Lease until 2016, USEC retains the right under the Lease to terminate the Lease for convenience at any time upon two years notice to DOE.

The Company, or its subsidiaries, is also a party to a number of other agreements or arrangements with the U.S. government, as described in the Company’s annual report on Form 10-K/A.
