services  rendered by ANR after  November 1, 1994 with respect to the storage of
the Storage  Account  Volumes  transferred  to Atlanta or the withdrawal of such
Storage Account Volumes from storage.

5.  Southern  agrees that,  as a result of the  transfer of the Storage  Account
Volumes by Southern to Atlanta,  ANR has fulfilled its  obligations  to Southern
under the Agreements  with respect to such Storage  Account Volumes and that ANR
shall have no contractual  obligations from and after November 1, 1994, to store
or redeliver such Storage Account Volumes to or for the account of Southern.
