W I T N E S S E T H:

        WHEREAS, Borrower, Pacific Energy Partners, Administrative Agent,
Syndication Agent, Co-Documentation Agents, Arrangers and the lenders party
thereto ("Lenders") have entered into that certain Credit Agreement dated as of
July 19, 2002 (the "Original Agreement") for the purpose and consideration
therein expressed, whereby Lenders became obligated to make loans to Borrower as
therein provided; and

        WHEREAS, Borrower, Pacific Energy Partners, Administrative Agent,
Syndication Agent, Co-Documentation Agent, Arrangers and Lenders desire to amend
the Original Agreement for the purposes expressed herein;

        NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein and in the Original Agreement and in
consideration of the loans and other credit that may hereafter be extended by
Lenders to Borrower, and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto do hereby
agree as follows:

ARTICLE I.
Definitions and References

        Section 1.1. Terms Defined in the Original Agreement. Unless the context
otherwise requires or unless otherwise expressly defined herein, the terms
defined in the Original Agreement shall have the same meanings whenever used in
this First Amendment.

ARTICLE II.
Amendments to Original Agreement

        Section 2.1. Guaranties of Subsidiaries. Subsection (b) of Section 6.13
of the Original Agreement is hereby amended in its entirety to read as follows:

        (b)   Pacific Pipeline System LLC, Pacific Terminals LLC and each other
PUC Restricted Subsidiary shall not be required to provide a Guaranty pursuant
to subsection (a) of this Section 6.13 unless regulatory approval shall have
been obtained for such Guaranty from the applicable public utility commission
having such regulatory authority over such PUC Restricted Subsidiary (in this
Section called the applicable "PUC"). Pacific Energy Partners and Borrower shall
cause Pacific Pipeline System LLC and Pacific Terminals LLC to file an
application for the approval of the applicable PUC for a Guaranty of the
Obligations on or prior to the consummation of the EPTC Acquisition and to use
its best efforts to obtain the approval of the applicable PUC for a Guaranty of
the Obligations as promptly as possible after such filing. Pacific Energy
Partners and Borrower shall cause each PUC Restricted Subsidiary other than
Pacific Pipeline System LLC and Pacific Terminals LLC to use its best efforts to
obtain the approval of the applicable PUC for a Guaranty of the Obligations on
or prior to the consummation of the acquisition of such PUC Restricted
Subsidiary. If the EPTC Acquisition is abandoned or terminated, Pacific Energy
Partners and Borrower shall cause Pacific Pipeline System LLC to use its best
efforts to obtain the approval of the applicable PUC for a Guaranty of the
Obligations as promptly as possible after such abandonment or termination.
Pacific Energy Partners and Borrower shall cause the PUC Restricted Subsidiary
to use such best efforts to obtain the approval of the applicable PUC for an
absolute and unconditional Guaranty except to the extent that Restricted Persons
reasonably determine that a request for a limited Guaranty substantially
increases the likelihood of obtaining such approval, and, to the extent
expressly required by the applicable PUC, the maximum principal amount of such
Guaranty shall be limited to the maximum amount specified by the applicable PUC
approval; provided further that such request for approval shall be for not less
than $176,000,000 in the case of Pacific Pipeline System LLC and not less than
the purchase price for the assets to be acquired under the EPTC Acquisition
Documents in the case of Pacific Terminals LLC.

        Section 2.2. Agreement to Deliver Security Documents. Subsection (b) of
Section 6.16 of the Original Agreement is hereby amended in its entirety to read
as follows:

        (b)   Pacific Pipeline System LLC, Pacific Terminals LLC and each other
PUC Restricted Subsidiary shall not be required to execute and deliver any
Security Document pursuant to subsection (a) of this Section 6.16 unless
regulatory approval shall have been obtained for such Security Document from the
applicable public utility commission having such regulatory authority over such
PUC Restricted Subsidiary (in this Section called the applicable "PUC"). Pacific
Energy Partners and Borrower shall cause Pacific Pipeline System LLC and Pacific
Terminals LLC to file an application for the approval of the applicable PUC for
Liens and security interests covering any Real Property Collateral now owned or
hereafter acquired by such Person to secure the obligations in such PUC
Restricted Subsidiary's Guaranty on or prior to the consummation of the EPTC
Acquisition and to use its best efforts to obtain the approval of the applicable
PUC for such Liens and security interests as promptly as possible after such
filing to secure the obligations in such PUC Restricted Subsidiary's Guaranty
(if delivered pursuant to Section 6.13). If the EPTC Acquisition is abandoned or
terminated, Pacific Energy Partners and Borrower shall cause Pacific Pipeline
System LLC to use its best efforts to obtain the approval of the applicable PUC
for such Liens and security interests as promptly as possible after such
abandonment or termination. Pacific Energy Partners and Borrower shall cause
each PUC Restricted Subsidiary other than Pacific Pipeline System LLC and
Pacific Terminals LLC to use its best efforts to obtain the approval of the
applicable PUC for Liens and security interests covering any Real Property
Collateral now owned or hereafter acquired by such Person (other than as
provided in subsection (a) of this Section 6.16 with respect to certain property
of Pacific Marketing and Transportation LLC), to secure the obligations in such
PUC Restricted Subsidiary's Guaranty (if delivered pursuant to Section 6.13).

ARTICLE III.

as of the date first above written when, and only when Agent shall have
received, at Agent's office a counterpart of this First Amendment executed and

hereunder.

        (c)   The execution and delivery by Borrower of this First Amendment,

the transactions contemplated hereby and thereby do not and will not conflict
with any provision of law, statute, rule or regulation or of the organizational
documents of Borrower, or of any material agreement, judgment, license, order or

lien, charge or encumbrance upon any assets or properties of Borrower. Except
for those which have been obtained, no consent, approval, authorization or order
of any court or governmental authority or third party is required in connection

hereby amended is hereby ratified and confirmed in all respects. Any reference
to the Credit Agreement in any Loan Document shall be deemed to be a reference
to the Original Agreement as hereby amended. The execution, delivery and
effectiveness of this First Amendment shall not, except as expressly provided
herein, operate as a waiver of any right, power or remedy of Lenders or Agent
under the Credit Agreement, the Notes, or any other Loan Document nor constitute
a waiver of any provision of the Credit Agreement, the Notes or any other Loan
Document.

        Section 5.2. Survival of Agreements. All representations, warranties,
covenants and agreements of Borrower herein shall survive the execution and
delivery of this First Amendment and the performance hereof, and shall further
survive until all of the Obligations are paid in full. All statements and

shall be deemed to constitute representations and warranties by, and agreements
and covenants of, Borrower under this First Amendment and under the Credit
Agreement.

        Section 5.3. Loan Documents. This First Amendment is a Loan Document,
and all provisions in the Credit Agreement pertaining to Loan Documents apply

and construed in accordance with the laws applicable to the Credit Agreement.

        Section 5.5. Counterparts. This First Amendment may be separately
executed in counterparts and by the different parties hereto in separate
