         RIVER GAS PURCHASE CONTRACT, COOK INLET, ALASKA

This letter is written pursuant to the Shell Oil Company (SOC)/Shell Western E&P
Inc. (SWEPI) Services Agreement.

In accordance with the provisions of the Gas Purchase Contract dated December
20, 1982, as amended (Contract), between SOC (predecessor in interest of SWEPI),
and Alaska Pipeline Company (APL), we are enclosing herewith a copy of the
Partial Assignment of Gas Purchase Contract between SWEPI and Chevron U.S.A.
whereby SWEPI assigns one-half of its remaining interest in the Contract. With
this assignment, SWEPI, Arco and Chevron each now own a separate one-third
interest in and to the Contract. We asked that APL institute direct payment to
Chevron U.S.A. for its one-third interest in Beluga River sales to APL. If you
have any questions on the foregoing, please feel free to give me or a member of
my staff a call.

                                    Regards,

                                    /S/ W.T. Coppersmith
