expenses which may be paid or incurred by the Agent, either Issuing Bank or any

the Obligations and/or enforcing any rights with respect to, or collecting
against, any Guarantor under this Guaranty Agreement; provided, however, that,
notwithstanding anything herein or in any other Financing Document to the

such Guarantor.





                                      -3-

         (b)     Each Guarantor agrees that the Obligations may at any time and
from time to time exceed the Maximum Guaranteed Amount for such Guarantor
without impairing this Guaranty Agreement or affecting the rights and remedies
of the Agent, either Issuing Bank or any Lender.

         (c)     No payment or payments made by the Company, any Guarantor, any
other guarantor or any other Person or received or collected by the Agent,
either Issuing Bank or any Lender from the Company, any Guarantor, any other
guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Obligations shall be deemed to modify,
reduce, release or otherwise affect the liability of each Guarantor hereunder,
which shall, notwithstanding any such payment or payments, other than payments
made by such Guarantor in respect of the Obligations or payments received or
collected from such Guarantor in respect of the Obligations, remain liable for
the Obligations up to the Maximum Guaranteed Amount for such Guarantor until
the Obligations are paid in full.

         (d)     It is the intention of the parties hereto that all
intercompany indebtedness either owed to or by any Guarantor not be included as
either an asset or a liability, respectively, in determining the solvency or
capital of any Guarantor.  Accordingly, each Guarantor agrees that in
connection with any determination of the Maximum Guaranteed Amount, such
intercompany indebtedness may be treated in the manner that would achieve the
result intended by the first sentence of this subsection (d).

         (e)     Right to Collect on the Notes.  The Company and the Guarantors
are personally obligated and fully liable for the amounts due under the Notes.
The Lenders have the right to sue on the Notes and obtain a personal judgment
against the Company and the Guarantors for satisfaction of the amounts due
under the Notes either before or after a judicial foreclosure of the Alaska
Deed of Trust under Alaska Statute 09.45.170 - 09.45.220.

         (f)     Senior Debt.  Tesoro Alaska's guarantee of the payment of the
Obligations constitutes Senior Debt as such term is defined in that certain
Subordination Agreement dated December 15, 1993, among the Company, Tesoro
Alaska, and the State of Alaska, attached as Exhibit 7 to the Settlement
Agreement dated December 15, 1992, among the Company, Tesoro Alaska, and the
State of Alaska.

         3.  Right of Contribution.  Each Guarantor agrees that after all the
Obligations have been paid in full that if its then current Net Payments are
less than the amount of its then current Contribution Obligation, such
Guarantor shall pay to the other Guarantors an amount (together with any
payments required of the other Guarantors by this Section 3) such that the Net
Payments made by all Guarantors in respect of the Obligations shall be shared
among all of the Guarantors in proportion to their respective Contribution
Percentage. The provisions of this Paragraph 3 shall in no respect limit the
obligations and liabilities of any Guarantor to the Agent, the Issuing Banks or
any Lender, and each Guarantor shall remain liable to the Agent, the Issuing
Banks and each Lender for the full amount guaranteed by such Guarantor
hereunder.

         4.  Right of Set-off.  The Agent, the Issuing Bank and each Lender is
hereby irrevocably authorized upon the occurrence of an Event of Default
without notice to the Guarantors, any such notice being expressly waived by
each Guarantor, to set-off and credit against any credits, indebtedness or
claims, in any currency, in each case whether direct or indirect or contingent
or matured or unmatured, at any time held or owing by the Agent, either Issuing
Bank or any Lender to or for the credit or the account of any Guarantor, or any
part thereof in such amounts as the Agent, such Issuing Bank or such Lender may
elect, against and on account of the obligations and liabilities of the
applicable Guarantor to the Agent, the Issuing Banks and the Lenders hereunder
and claims of every nature and description of the Agent, the Issuing Banks and
the Lenders against such Guarantor, in any currency, whether arising hereunder,
under the Credit Agreement, any other Financing Document or otherwise, as the
Agent, either Issuing Bank or any Lender may elect, whether or not the Agent,
such Issuing Bank or such Lender has made any demand for payment and although
such obligations, liabilities and claims may be contingent or unmatured.  The
Agent agrees to notify (promptly after receipt of notice by the Agent) the
Company and the applicable Guarantor of any such set-off and the application
made by the Agent, such Issuing Bank or any such Lender, provided that the
failure to give such notice shall not affect the validity of such set-off and
application.  The rights of the Agent, either Issuing Bank and each Lender
under this paragraph are in addition to other rights and remedies (including,
without limitation, other rights of set-off) which any such Person may have.
If foreign currency is exchanged for U.S. Dollars by the Agent, either Issuing
Bank or any Lender, such Person shall use the rate of exchange prevailing at
the time for customers exchanging a similar amount of currency.

         5.  No Subrogation.  Notwithstanding any payment or payments made by
any Guarantor hereunder or any set-off or application of funds of any
Guarantors by the Agent, either Issuing Bank or any Lender, any such Guarantor
shall not be entitled to be subrogated to any of the rights of the Agent,
either Issuing Bank or any Lender against the Company or any collateral
security or guaranty or right of offset held by any such Person for the payment
of the Obligations, nor shall any Guarantor seek or be entitled to seek any
contribution or reimbursement from the Company in respect of payments made by
any such Guarantor hereunder, until all Obligations are paid in full.  If any
amount shall be paid to any Guarantor on account of such subrogation rights at
any time when all of the Obligations shall not have been paid in full, such
amount shall be held by such Guarantor in trust for the Agent, the Issuing
Banks and the Lenders, segregated from other funds of such Guarantor, and
shall, forthwith upon receipt by such Guarantor, be turned over to the Agent in
the exact form received by such Guarantor (duly indorsed by such Guarantor to
the Agent, if required), to be applied against the Obligations, whether matured
or unmatured in such order as the Agent may determine.

         6.  Amendments, etc. with respect to the Obligations; Waiver of
Rights.  Each Guarantor shall remain obligated hereunder notwithstanding that,
without any reservation of rights against the Guarantors and without notice to
or further assent by the Guarantors, any demand for payment of any of the
Obligations made by the Agent, either Issuing Bank or any Lender may be
rescinded and any of the Obligations continued, and the Obligations, or the
liability of any other party upon or for any part thereof, or any collateral
security or guaranty therefor or right of offset with respect thereto, may,





                                      -5-
   6
from time to time, in whole or in part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by the Agent, the
Issuing Banks or the Lenders and the Credit Agreement, the Notes and any
collateral security document or other guaranty or document in connection
therewith (including, without limitation, the other Financing Documents) may be
amended, modified, supplemented or terminated, in whole or in part, as the
Agent, the Issuing Banks or the Lenders may deem advisable from time to time,
and any collateral security or guaranty or right of offset at any time held by
the Agent, the Issuing Banks or the Lenders for the payment of the Obligations
may be sold, exchanged, waived, surrendered or released, all without the
necessity of any reservation of rights against the Guarantors and without notice
to or further assent by the Guarantors which will remain bound hereunder,
notwithstanding any such renewal, extension, modification, acceleration,
compromise, amendment, supplement, termination, sale, exchange, waiver,
surrender or release.  Neither the Agent, either Issuing Bank nor any Lender
shall have an obligation to protect, secure, perfect or insure any Lien at any
time held as security for the Obligations or this Guaranty Agreement or any
Property subject thereto. When making any demand hereunder against any
Guarantor, the Agent may, but shall be under no obligation to, make a similar
demand on the Company or any other guarantor, and any failure by the Agent to
make any such demand or to collect any payments from the Company or any such
other guarantor, or any release of the Company or other guarantor, shall not
relieve any such Guarantor of its obligations or liabilities hereunder, and
shall not impair or affect the rights and remedies, express or implied, or as a
matter of law, of the Agent, the Issuing Banks of the Lenders against each
Guarantor.  For the purposes hereof "demand" shall include the commencement and
continuance of any legal proceedings.

         7.  Guaranty Absolute and Unconditional.  Each Guarantor waives any
and all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Agent, either Issuing
Bank or any Lender upon this Guaranty Agreement or acceptance of this Guaranty
Agreement, and the Obligations (and any of them) shall conclusively be deemed
to have been created, contracted or incurred and extended, amended and waived
in reliance upon this Guaranty Agreement, and all dealings between the Company
or the Guarantors and the Agent, either Issuing Bank or any Lender shall
likewise be conclusively presumed to have been had or consummated in reliance
upon this Guaranty Agreement.  Each Guarantor waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment, notice of
intention to accelerate maturity and notice of acceleration of maturity to or
upon the Company or the Guarantors with respect to the Obligations.  Each
Guarantor understands and agrees that this Guaranty Agreement shall be
construed as a continuing, absolute, completed, unconditional (except as
expressly conditioned pursuant to the terms hereof) and irrevocable guarantee
of payment and not of collection without regard to (a) the validity, regularity
or enforceability of the Credit Agreement, the other Financing Documents, any
of the Obligations or any collateral security or guaranty therefor or right of
offset with respect thereto at any time or from time to time held by the Agent,
either Issuing Bank or any Lender, (b) any defense, set-off or counterclaim
which may at any time be available to or be asserted by the Company or any
other Person liable for the Obligations against the Agent, either Issuing Bank
or any Lender, or (c) any other circumstance whatsoever (with or without notice
to or knowledge of the Company or any Guarantor) which constitutes, or might be
construed





                                      -6-
   7
to constitute, an equitable or legal discharge of the Company or any other
Person liable for the Obligations, or of any Guarantor under this Guaranty
Agreement, in bankruptcy or in any other instance.  When pursuing its rights
and remedies hereunder against any Guarantor, the Agent, the Issuing Banks and
the Lenders may, but shall be under no obligation to, pursue such rights and
remedies as they may have against the Company or any other Person or against
any collateral security or guaranty for the Obligations or any right of offset
with respect thereto, and any failure by the Agent, the Issuing Banks or the
Lenders to pursue such other rights or remedies or to collect any payments from
the Company or any such other Person or to realize upon any such collateral
security or guaranty or to exercise any such right of offset, or any release of
the Company or any such other Person or any such collateral security, guaranty
or right of offset, shall not relieve any Guarantor of any liability hereunder,
and shall not impair or affect the rights and remedies, whether express,
implied or available as a matter of law, of the Agent, either Issuing Bank or
any Lender against any Guarantor.  This Guaranty Agreement shall remain in full
force and effect and be binding in accordance with and to the extent of its
terms upon each Guarantor and the respective successors and assigns thereof,
and shall inure to the benefit of the Agent, Issuing Banks and the Lenders, and
the respective successors, indorsees, transferees and assigns thereof, until
all the Obligations and the obligations of the Guarantors under this Guaranty
Agreement shall have been satisfied by payment in full.

         8.  Reinstatement.  This Guaranty Agreement shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Obligations is rescinded or must otherwise be
restored or returned by the Agent, either Issuing Bank or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Company or any Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Company or any Guarantor or any substantial part of such Person's property, or
otherwise, all as though such payments had not been made.

         9.  Payments.  Each Guarantor hereby guarantees that payments
hereunder will be paid, without set-off or counterclaim and in immediately
available funds and in lawful currency of the United States of America, to
Agent in Houston, Texas, at the Agent's Payment Office, not later than 11:00

         and in good standing under the laws of the State of Delaware and has

exercising, on the part of the Agent, either Issuing Bank or any Lender, any
right, power or privilege hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any right, power or privilege preclude
any other or further exercise thereof, or the exercise of any other power,
privilege or right.  A waiver by the Agent, either Issuing Bank or any Lender
of any right or remedy hereunder on any one occasion shall not be construed as
a bar to any right or remedy which any such Person would have on any future

exercised singly or concurrently, and are not exclusive of any rights or
remedies provided by law.

parties hereunder shall be construed in accordance with and be governed by the
law (without giving effect to the conflict of law principles thereof) of the
State of Texas.

         (b)     ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT,
MAY BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF
AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, HOUSTON DIVISION, AND, BY EXECUTION
AND DELIVERY OF THIS AGREEMENT, EACH GUARANTOR HEREBY ACCEPTS FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS.  EACH GUARANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION,
INCLUDING BUT NOT LIMITED TO ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.

         (c)     THE COMPANY AND THE AGENT, EACH  ISSUING BANK AND EACH LENDER
HEREBY (I) IRREVOCABLY AND UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT
PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO
THIS GUARANTY AGREEMENT OR ANY FINANCING DOCUMENT AND FOR ANY COUNTERCLAIM
THEREIN; (II) CERTIFY THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OF
COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR
IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE
THE FOREGOING WAIVERS, AND (III) ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO ENTER
INTO THIS AGREEMENT, THE FINANCING DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED
HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS CONTAINED IN THIS SECTION.

         (d)     Each Guarantor that is not a Texas corporation hereby
irrevocably designates the General Counsel of the Company (as of the date
hereof, James C. Reed, Jr.) located at 8700 Tesoro Drive, San Antonio, Texas
78217, as the designee, appointee and agent of such Guarantor to receive, for
and on behalf of such Guarantor, service of process in such respective
jurisdictions in any legal action or proceeding with respect to this Agreement,
the Notes, the Security Instruments or the other Financing Documents.  It is
understood that a copy of such process served on such agent will be promptly
forwarded by mail to such Guarantor at its address set forth opposite its
signature below, 




                                      -9-
   10
but the failure of such Guarantor to receive such copy shall not affect in any
way the service of such process.  Each Guarantor further irrevocably consents to
the service of process of any of the aforementioned courts in any such action or
proceeding by the mailing of copies thereof by registered or certified mail,
postage prepaid, to such Guarantor at its said address, such service to become
effective 30 days after such mailing.

         (e)     Nothing herein shall affect the right of the Agent or any
Lender or any holder of a Note to serve process in any other manner permitted
by law or to commence legal proceedings or otherwise proceed against any
Guarantor in Texas or any other jurisdiction in which assets of any Guarantor
are located.

         15.  Severability.  Any provision of this Guaranty Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         16.  Paragraph Headings.  The Paragraph headings used in this Guaranty
Agreement are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation
hereof.

         17.  Interest.  It is the intention of the parties hereto to conform
strictly to usury laws applicable to each Lender and the Transactions.
Accordingly, if the Transactions would be usurious as to any Lender under
applicable law, then, notwithstanding anything to the contrary in the Notes,
this Agreement or in any Financing Document or agreement entered into in
connection with the Transactions or as security for the Obligations, it is
agreed as follows:  (i) the aggregate of all consideration which constitutes
interest as to any Lender under applicable law that is contracted for, taken,
reserved, charged or received by such Lender under the Notes, this Agreement or
under any of the Financing Documents or agreements or otherwise in connection
with the Transactions shall under no circumstances exceed the maximum amount
allowed by such applicable law, (ii) in the event that the maturity of the
Notes is accelerated for any reason, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest as to
any Lender under applicable law may never include more than the maximum amount
allowed by such applicable law, and (iii) excess interest, if any, provided for
in this Agreement or otherwise in connection with the Transactions shall be
cancelled automatically and, if theretofore paid, shall be credited by such
Lender on the principal amount of the Obligations (or, to the extent that the
principal amount of the Obligations shall have been or would thereby be paid in
full, refunded by such Lender to the Company).  The right to accelerate the
maturity of the Notes does not include the right to accelerate any interest
which has not otherwise accrued on the date of such acceleration, and the
Lenders do not intend to collect any unearned interest in the event of
acceleration.  All sums paid or agreed to be paid to each Lender for the use,
forbearance or detention of sums included in the Obligations shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and
spread throughout the full term of the Notes until payment in full so that the
rate or amount of interest on 





                                      -10-
   11
account of the Obligations does not exceed the applicable usury ceiling, if any.
As used in this Section, the term "applicable law" shall mean the laws of the
State of Texas (or of any other jurisdiction whose laws may be mandatorily
applicable notwithstanding other provisions of this Agreement) or laws of the
United States of America applicable to any Lender and the Transactions, which
would permit such Lender to contract for, charge, take, reserve or receive a
greater amount of interest than under Texas (or such other jurisdiction's) law.
To the extent that Article 5069-1.04 of the Texas Revised Civil Statutes is
relevant to the Lenders for the purpose of determining the Highest Lawful Rate,
the Lenders hereby elect to determine the applicable rate ceiling under such
Article by the indicated (weekly) rate ceiling from time to time in effect,
subject to the Lenders' right subsequently to change such method in accordance
with applicable law.   In no event shall the provisions of Tex. Rev. Civ. Stat.
art. 5069-2.01 through 5069-8.06 or 5069-15.01 through 5069-15.11 be applicable
to the Loans evidenced hereby.

         18.  Counterparts.  This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original but all of which
shall together constitute one and the same instrument.
