          Assignment of Guarantee, dated as of __________ 1, 1995 (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:

                                   ARTICLE I

assigned to such terms in Schedule 1 to this Assignment, and the definitions of
such terms shall be equally applicable to both the singular and plural forms of
such terms.

right, title and interest in and to the Guarantee, including without limitation
any moneys whatsoever payable to the Owner under the Guarantee, together with
the income and proceeds thereof and all other rights and benefits whatsoever
accruing to the Owner under the Guarantee; provided, however, that the Owner
shall keep the Lender fully and effectively indemnified from and against all
actions, losses, claims, proceedings, costs, demands and liabilities which may
be suffered by the Lender under or by virtue of the Guarantee or this
Assignment; provided further, however, in the event that the Serial Obligations
are satisfied and paid in full pursuant to the terms and conditions of the

interest made by the Owner pursuant to the terms of this Assignment will be
solely and exclusively for the benefit of the Lender as Lender under the Term
Loan Agreement and this Assignment will be security solely and exclusively for
the Term Obligations.

          (b)  Any and all rights assigned herein may be further assigned by the
Lender, including, without being limited to, assignments in connection with the
enforcement of the assignments made by this Assignment and any subsequent holder
of this Assignment shall succeed to and have all the rights and powers of the
Lender under this Assignment.
