     SECTION 4. Except as expressly amended hereby, the Contract shall remain unchanged and in full force and effect.

     SECTION 5. 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.

     SECTION 6. This Amendment shall enter into force and effect, the rights and obligations of the Parties under this Amendment shall arise and the Parties shall be bound by the obligations and entitled to the rights as set forth in this Amendment upon and as of the first day by which (i) the approval or endorsement of this Amendment by the Government of the Russian Federation or its authorized agency(ies) of the Government of the Russian Federation has been obtained and (ii) written confirmation that USEC, as the Executive Agent for the Government of the United States of America, is authorized to sign this Amendment (or confirmation that the approval of the U.S. Government is not required) has been obtained from the U.S. State Department as the authorized agency of the U.S. Government.

Each Party shall use its best efforts to secure, as soon as possible, the approval, endorsement or confirmation, as applicable, of its respective government.
