     (b) References to Techsnabexport Co., Ltd. shall be considered references to OA Techsnabexport. This change reflects only a more precise translation of TENEX’s name and no change to the legal entity that is TENEX.

     SECTION 2. Except as amended hereby, the Contract shall remain unchanged and in full force and effect. In the event that any conflict arises between this Amendment and the Contract, TENEX and USEC shall resolve such conflict consistent with the purpose of this Amendment as set forth in the recitals herein.

     SECTION 3. This Amendment may be executed in two or more counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute one and the same instrument.
