                Assignment of Guarantee, dated as of __________ 1, 1994
(the "Assignment"), between California Petroleum Transport Corporation, a
corporation organized under the laws of the State of Delaware (the
"Lender") and CalPetro Tankers (Bahamas I)  Limited, a company organized
under the laws of The Commonwealth of the Bahamas (the "Owner").

                             PRELIMINARY STATEMENT

            The Owner has requested that the Lender make two loans to the
Owner: one loan in the aggregate principal amount equal to $____________ (the
"Term Loan") and one series of loans in the aggregate principal amount equal
to $____________ (collectively, the "Serial Loans" and, collectively with the
Term Loan, the "Loans").  The Loans will be made pursuant to the terms and
conditions of two Loan Agreements, each dated as of the date hereof, each
between the Lender and the Owner.  The net proceeds of the Serial Loans and
the Term Loan will be used by the Owner to acquire the m.t. _________ (the
"Vessel") from Chevron Transport Corporation (the "Initial Charterer").  The
Vessel will be bareboat chartered to the Initial Charterer pursuant to the
Bareboat Charter (the "Initial Charter"), dated as of the date hereof, between
the Owner and the Initial Charterer.  The obligations of the Initial Charterer
under the Initial Charter will be guaranteed by Chevron Corporation (the
"Guarantor") pursuant to a Guarantee, dated as of the date hereof (the
"Guarantee").  As collateral security for its obligations under the Loan
Agreements, the Owner will assign, pledge, mortgage and grant the Lender a
security interest in, inter alia, the Vessel, the Initial Charter and the
Guarantee.

            NOW, THEREFORE, in consideration of the premises and of the
covenants herein contained, the parties hereto covenant and agree as follows:
