EXHIBITS:           A    Joinder Agreement

<PAGE>
            This COLLATERAL AGENCY AGREEMENT, dated as of April 17, 2003 (this
"Agreement"), is entered into by and among TESORO PETROLEUM CORPORATION, a
Delaware corporation (the "Company"), THE SUBSIDIARIES OF THE COMPANY PARTY
HERETO (the "Guarantors"), GOLDMAN SACHS CREDIT PARTNERS L.P., as Administrative
Agent under the Term Loan Agreement (each, as defined below), THE BANK OF NEW
YORK, as Trustee under the Indenture (each, as defined below), and WILMINGTON
TRUST COMPANY, as Collateral Agent (together with its successors in such
capacity, the "Collateral Agent").

                                    RECITALS

            1. The Company intends to borrow $200,000,000 in principal amount of
Term Loans (the "Initial Term Loans") under the Term Loan Agreement dated as of
April 17, 2003 (the "Term Loan Agreement") by and among the Company, the
Guarantors, the lenders from time to time party thereto, the Administrative
Agent (together with its successors in such capacity, the "Administrative
Agent") and Goldman Sachs Credit Partners L.P., as sole lead arranger, sole
bookrunner and syndication agent.

            2. The Company intends to issue $375,000,000 in principal amount of
8.00% Senior Secured Notes due April 15, 2008 (the "Initial Notes") pursuant to
the Indenture dated as of April 17, 2003 (the "Indenture") by and among the
Company, the Guarantors and The Bank of New York, as Trustee (together with its
successors in such capacity, the "Trustee").

            3. Pursuant to the Term Loan Agreement, the Guarantors guarantee
payment of the Initial Term Loans and all other Term Loan Obligations. Pursuant
to the Indenture, the Guarantors guarantee payment of the Initial Notes and all
other Note Obligations.

            4. The Term Loan Agreement and Indenture require the Company and the
Guarantors to secure payment of the Initial Term Loans and the Initial Notes and
other Secured Obligations, Equally and Ratably, by security interests in the
Collateral. Without providing any commitments to the Company as to the funding
of any future indebtedness, the Term Loan Agreement and Indenture permit the
Company from time to time to incur Indebtedness which it is otherwise permitted
to incur under the Term Loan Agreement and Indenture in the form of additional
Term Loans borrowed under the Term Loan Agreement or additional Notes issued
under the Indenture (or both) and to secure such additional Term Loans and
additional Notes, Equally and Ratably with the Initial Term Loans and the
Initial Notes, by such security interests in the Collateral, up to an aggregate
principal amount (including the Initial Term Loans and the Initial Notes) not
exceeding $725,000,000 at any one time outstanding (the "Secured Principal
Cap").

            5. The Term Loan Agreement and Indenture further require that such
security interests in the Collateral be granted pursuant to the Security
Documents to a collateral agent acting for the benefit of the holders of Term
Loans, Notes and other Secured Obligations. This Agreement sets forth the terms
on which the Collateral Agent has undertaken to accept, hold and enforce such
security interests and all related rights, interests and powers as agent for,
and for the benefit exclusively of, the present and future holders of the Term
Loans, Notes and other Secured Obligations.

bankruptcy case or insolvency or liquidation proceeding in respect of any claim
upon any Secured Obligation that is allowed or enforceable therein as a claim
secured by Collateral pursuant to the Security Documents.

Section 2.7  Credit Bid Rights.

      (a) If, during the continuance of an Actionable Default, the Collateral
Agent forecloses any of its Liens upon any Collateral, whether by public sale or
private sale or judicial foreclosure or otherwise, and if directed by an Act of
the Secured Debtholders to exercise its credit bid rights as provided in this
Section 2.7(a), the Collateral Agent, acting for and on behalf of the Secured
Debtholders and other holders of Secured Obligations, shall be entitled (to the
fullest extent it may lawfully do so) to use and apply then matured Secured
Obligations as a credit on account of the purchase price payable by the
Collateral Agent for any Collateral sold to the Collateral Agent at the
corresponding foreclosure sale, for all purposes related to bidding and making
settlement or payment of the purchase price at such foreclosure sale.

      (b) If, in connection with or, during the continuance of an Actionable
Default, in anticipation of any foreclosure of any of the Collateral Agent's
Liens upon any Collateral, Term Loans and Notes representing at least a majority
in outstanding principal amount of Term Loans and Notes then outstanding are
transferred to and registered in the name of a single transferee for purposes of
facilitating or executing a bid for such Collateral at the corresponding
foreclosure sale, such transferee shall be entitled (to the fullest extent it
may lawfully do so) to use and apply all then matured Secured Obligations
outstanding to such transferee as a credit on account of the purchase price
payable by such transferee for any Collateral sold to such transferee at such
foreclosure sale, for all purposes related to bidding and making settlement or
payment of the purchase price at such foreclosure sale, but only if all Secured
Debtholders consent thereto or if:

            (i) each Secured Debtholder has been offered the opportunity to
transfer to such transferee any or all of the Term Loans and Notes outstanding
held by such Secured Debtholder on terms equivalent to the most favorable terms
offered by such transferee to any Secured Debtholder for or in connection with
any transfer of Term Loans or Notes to such transferee; and

                                       6
<PAGE>
            (ii) effective provision is made (or found by order of a court of
competent jurisdiction to have been made) for sharing proceeds of the Collateral
Equally and Ratably, even if the proceeds received by Secured Debtholders other
than such transferee are different in kind (if reasonably equivalent in value
with at least equivalent liquidity) from the proceeds to be realized by such
transferee if it is the successful bidder at the foreclosure sale.

      (c) Each of the Company and Guarantors hereby grants, confirms and agrees
to cooperate with and permit the exercise and enforcement of the rights set
forth in this Section 2.7.

Section 2.8  Powers of the Collateral Agent.

      (a) The Collateral Agent is irrevocably authorized and empowered to enter
into and perform its obligations and protect, perfect, exercise and enforce its
interest, rights, powers and remedies, in each case pursuant to the Security

requested in any lawful directions given to it from time to time in respect of
any matter by Act of the Secured Debtholders.

      (b) Subject to Article 4, the Collateral Agent shall take direction only

the Secured Debtholders or by the Administrative Agent or Trustee or otherwise
by any Person) which imposes, or purports to impose, upon the Collateral Agent
any obligation not set forth in or arising under this Agreement or any other
Security Document accepted by the Collateral Agent shall be binding upon the
Collateral Agent unless the Collateral Agent elects, at its sole option, to
accept direction (i) pursuant to an Act of the Secured Debtholders or (ii) from
the Administrative Agent and the Trustee as required or permitted by the Term
Loan Agreement and the Indenture.

      (d) No Act of the Secured Debtholders shall be effective to impose any
obligation or liability upon any Secured Debtholder, the Administrative Agent or
the Trustee, unless it is a signatory party thereto.

      (e) The Administrative Agent and the Trustee are party to this Agreement
solely to confirm their consent to the undertaking of the Collateral Agent set
forth in Section 2.1(a) and their acceptance of the rights granted to them by
this Agreement. Neither the Administrative Agent nor the Trustee nor any Secured
Debtholder nor any other holder of Secured Obligations shall have (i) any
obligation under this Agreement or under any Act of the Secured Debtholders to
which it is not a signatory party; (ii) any responsibility or duty whatsoever in
respect of the Collateral or the Security Documents or any other interest,
right, power or remedy granted to or enforceable by the Collateral Agent, it
being understood and agreed by the Collateral Agent and by the Company and the

breach of, the obligations of the Collateral Agent set forth in or arising under
the Security Documents, including all obligations imposed by law upon a secured
party relating the protection, maintenance, release or enforcement of any
security interest in any Collateral or any other interest, right, power or
remedy of the Collateral Agent; or (iii) any liability whatsoever for

                                       7
<PAGE>
any act or omission of the Collateral Agent, whether or not constituting a
breach of its undertaking and obligations under this Agreement or otherwise
constituting wrongful conduct.

Section 2.9  For Sole Benefit of Holders of Secured Obligations, Equally and
Ratably. The Collateral Agent shall accept, hold, administer and enforce all
collateral security at any time delivered to it by the Company or any Guarantor
and all other interests, rights, powers and remedies at any time granted to or
enforceable by the Collateral Agent solely and exclusively for the benefit of
the Secured Debtholders and the other present and future holders from time to
time of Secured Obligations, Equally and Ratably, and shall distribute all cash
proceeds received by it in realization thereon or from enforcement thereof
solely and exclusively to the Administrative Agent and the Trustee, for the
benefit Equally and Ratably of the Secured Debtholders and the other present and
future holders of Secured Obligations.

                                  ARTICLE III.

              OBLIGATIONS ENFORCEABLE BY THE COMPANY AND GUARANTORS

release any property of the Company or a Guarantor described in such Officers'
Certificate from any Lien granted by a Security Document specified in such
Officers' Certificate, (b) if such release is required as a result of a Sale of
Collateral, the proceeds thereof will be applied in accordance with the Term
Loan Documents and the Note Documents, and (c) no Default or Event of Default
will result from the release of such Lien, accompanied by the proposed
instrument releasing such Lien as to such property and an Opinion of Counsel for
the Company to the effect that the release of such Lien as to such property is
permitted by the Term Loan Agreement and the Indenture or by an Act of the
Secured Debtholders and that such proposed instrument is effective solely to
release such Lien as to such property, without requiring the Collateral Agent to
make any representation or warranty in respect thereof, without releasing or
satisfying any obligation secured by such Lien, and without imposing any
obligation or liability upon the Collateral Agent or any other Person, then,

acknowledging in recordable form) such proposed instrument reasonably requested
by the Company and delivering it to the Company or such Guarantor.

an Officers' Certificate stating that the Company or any Guarantor intends to
incur Indebtedness that will be secured by a purchase money security interest
permitted under clause (4) in the definition of "Permitted Liens" upon property
identified therein with reasonable specificity to be acquired with such
Indebtedness, accompanied by (a) a proposed lien subordination agreement
subordinating the Liens under the Security Documents to such purchase money
security interest, to the extent it attaches to such property and secures
Indebtedness incurred to acquire such property, and (b) an Opinion of Counsel
for the Company to the effect that the subordination of such Liens to such

                                       8
<PAGE>
purchase money security interest, and to such extent, is permitted by the Term
Loan Agreement and the Indenture or by an Act of the Secured Debtholders and
that such proposed lien subordination agreement is effective solely to
subordinate such Lien as to such property to such extent, without requiring the
Collateral Agent to make any representation or warranty in respect thereof,
without releasing or satisfying any such Lien or any obligation secured thereby,
and without imposing any obligation or liability upon the Collateral Agent or
any other Person, then, subject to Article 4, the Collateral Agent will, within
ten Business Days thereafter, execute such lien subordination agreement and
deliver to the Company or such Guarantor, subject to and effective upon the
incurrence of such Indebtedness and the use of the proceeds thereof to acquire
such property.

Section 3.3 Delivery of Copies to the Administrative Agent and Trustee. The
Company shall deliver to the Administrative Agent and the Trustee a copy of each
Officers' Certificate delivered to the Collateral Agent pursuant to Section 3.1
or 3.2, together with copies of all documents delivered to the Collateral Agent
with such Officers' Certificate. The Administrative Agent and Trustee shall not
be obligated to take notice thereof or to act thereon.

Section 3.4 Collateral Agent not Required to Serve, File or Record. The
Collateral Agent is not required to serve, file, register or record any
instrument releasing or subordinating its security interest in any Collateral.

responsibilities except those expressly assumed by it in this Agreement and the
other Security Documents and shall not be required to take any action which is

Collateral Agent shall not be called upon to advise any party as to the wisdom
in taking or refraining to take any action with respect to the Collateral.

Section 4.2 Appointment of Co-Agents and Sub-Agents. The Collateral Agent may

responsible or liable for any act or omission of any such agent, sub-agent or
co-collateral agent.

will, at its expense, promptly execute, acknowledge and deliver such further
documents and do such other acts and things as may be necessary or appropriate,
or as the Collateral Agent, the Administrative Agent or the Trustee may
reasonably request, in order to assure and confirm that each Subsidiary required
by the Term Loan Agreement or the Indenture to guarantee payment of the Secured

perfect, protect, assure or enforce the Liens and benefits intended to be
conferred, as contemplated by the Indenture, the Term Loan Agreement and the

documents, instruments, certificates, notices and other documents and, subject
to the provisions of the Note Documents and the Term Loan Documents, take such
other actions in the name, place and stead of the Company or such Subsidiary,
