   12
       WHEREAS, Tennessee has determined that it must terminate, assign or
otherwise realign its existing gas supply contracts with producers, including
but not limited to the Contract, in connection with implementing the
requirements of Order No. 636 in order to provide the unbundled services
contemplated by the Commission in Order No. 636 and to mitigate any costs
resulting from the realignment of Tennessee's existing gas supply contracts.

       NOW, THEREFORE, for and in consideration of the mutual covenants,
promises and agreements herein contained Sellers and Tennessee hereby agree to
terminate the Contract and do hereby terminate the Contract as between Sellers
