     3.1. Borrower and Giant entered into an Agreement dated September
17, 1998, providing for the loan by Giant to Borrower of Four Million
Dollars ($4,000,000.00) upon the terms set forth therein (the "Loan

the period for repayment and for an additional advance by Lender to
Borrower of $1,000,000 (the "Additional Principal Amount" and,
collectively with the Original Principal Amount, the "Loan"). In
connection with the Modification Agreement, Borrower executed an Amended
and Restated Promissory Note of even date therewith.

affiliated with Giant, of a parcel of land containing approximately 40
acres located at 9540 East Jomax Road in the City of Scottsdale, Arizona

     3.5. It is the intent of the parties that certain of the proceeds
from the sale of the Property (the "Sale") be used in connection with
the repayment of the Loan.

                        PROMISSORY NOTE
                        James E. Acridge

Initial Principal Amount:  $4,000,000.00
Initial Rate:  Prime plus 2.0%
Date of Original Note:  September 17, 1998
Prior Additional Principal Amount:  $1,000,000.00
Prior Amended Rate: Prime plus 3.0% from and after December 23, 1998
Effective Date of Prior Amendment:  December 23, 1998
Current Principal Amount:  $5,000,000.00
Effective Date of This Amendment:  February 28, 2001


     For value received, JAMES E. ACRIDGE ("Borrower") promises to pay
to GIANT INDUSTRIES, INC., a Delaware corporation ("Giant"), or order,
in lawful money of the United States of America, (a) the initial
principal amount of four million dollars ($4,000,000.00), together with
interest on the unpaid initial principal amount from September 17, 1998,
until paid in full and (b) the additional principal amount of one
million dollars ($1,000,000.00), together with interest on the unpaid
additional principal amount from December 23, 1998, until paid in full.
The annual interest rate on this Note is the Prime rate as published in
the Western Edition of the Wall Street Journal on September 17, 1998,
plus two percent (2.0%) from September 17, 1998, through December 22,
1998, and the Prime rate as published in the Western Edition of the Wall
Street Journal on September 17, 1998, plus three percent (3%) from
December 23, 1998, until paid in full.

     Interest will accrue on the total principal amount of the Loan from
July 1, 1999 until March 28, 2001 (the "Extended Maturity Date"), at
which time all outstanding principal and interest shall be fully due and
payable.

     Borrower will pay Giant at Giant's corporate offices, 23733 North
Scottsdale Road, Scottsdale, Arizona, 85255, or at such other place as
Giant may designate in writing.  Unless otherwise agreed or required by
applicable law, payments will be applied first to accrued unpaid
interest, then to principal, and any remaining amount to any unpaid
collection costs and late charges.

     The annual interest rate for this Note is computed on the basis of
a 365-day year; that is, by applying the ratio of the annual interest
rate over a year of 365 days, multiplied by the outstanding principal
balance, multiplied by the actual number of days the principal balance
is outstanding.  Under no circumstances will the interest rate on this
Note be more than the maximum rate allowed by applicable law.

     Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due.

     Borrower will be in default if any of the following happens:  (a)
Borrower fails to make any payment when due; (b) Borrower fails to
comply with or to perform when due any other term, obligation, covenant,
or condition contained in this Note; (c) a receiver is appointed for any
part of Borrower's property, or any proceeding is commenced either by
Borrower or against Borrower under any bankruptcy or insolvency laws; or
(d) Borrower defaults under that certain Amended and Restated Loan
Agreement of even date herewith between Borrower and Giant.

     Upon default, Giant may declare the entire unpaid principal balance
on this Note and all accrued unpaid interest immediately due, and then
Borrower will pay that amount.  Upon default, including failure to pay
upon final maturity, Giant, at its option, may also, if permitted under
applicable law, increase the interest rate on this Note by an additional
three percent (3.0%).  The interest rate will not exceed the maximum
rate permitted by applicable law.  Giant may hire or pay someone else to
help collect this Note if Borrower does not pay, and Borrower also will
pay Giant that amount, if reasonable.  This includes, subject to any
limits under applicable law, Giant's reasonable attorneys' fees and
Giant's reasonable legal expenses whether or not there is a lawsuit,
including attorneys' fees and legal expenses for bankruptcy proceedings
(including efforts to modify or vacate any automatic stay or
injunction), appeals, and any anticipated post-judgment collection
services.  If not prohibited by applicable law, Borrower also will pay
any court costs, in addition to all other sums provided by Law.

     This Note has been delivered to Giant and accepted by Giant in the
State of Arizona.  If there is a lawsuit, Borrower agrees upon Giant's
request to submit to the jurisdiction of the courts of Maricopa County,
the State of Arizona.  This Note shall be governed by and construed in
accordance with the laws of the State of Arizona.

     Giant may delay or forgo enforcing any of its rights or remedies
under this Note without losing them.  Borrower, to the extent allowed by
law, waives presentment, demand for payment, protest and notice of
dishonor.  The parties agree that Giant may modify this loan without the
consent of or notice to anyone other than Borrower.

     Borrower agrees to an effective rate of interest that is the rate
specified in this Note plus any additional rate resulting from any other
charges in the nature of interest paid or to be paid in connection with
this Note.

     This Amended and Restated Note has been issued pursuant to an
initial Loan Agreement dated September 17, 1998, followed by various
amendments, including a Modification Agreement, of even date herewith,
between Borrower and Giant, the provisions of which are incorporated
herein by reference.

     PRIOR TO SIGNING THIS NOTE, BORROWER READ AND UNDERSTANDS ALL THE
PROVISIONS OF THIS NOTE.  BORROWER AGREES TO THE TERMS OF THE NOTE AND
ACKNOWLEDGES RECEIPT OF A COMPLETED COPY OF THE NOTE.


                                       BORROWER:
