3.       INTEREST; PAYMENTS.

         (a)      Absent an Event of Default hereunder, each advance made
                  hereunder shall bear interest at the Interest Rate. Throughout
                  the term of this Note, interest shall be computed by applying
                  the ratio of the annual interest rate over a year of 360 days,
                  multiplied by the outstanding principal balance, multiplied by
                  the actual number of days the principal balance is
                  outstanding.

         (b)      All payments of principal and interest due hereunder shall be
                  made (i) without deduction of any present and future taxes,
                  levies, imposts, deductions, charges or withholdings, which
                  amounts shall be paid by Maker, and (ii) without any other set
                  off. Maker will pay the amounts necessary such that the gross
                  amount of the principal and interest received by the holder
                  hereof is not less than that required by this Note.

         (c)      Maker shall make all payments of principal and interest due
                  hereunder, and any other amounts due hereunder due and
                  payable, on the Maturity Date. If any payment of principal and
                  interest to be made by Maker hereunder shall become due on a
                  day which is not a Business Day, such payment shall be made on
                  the next succeeding Business Day and such extension of time
                  shall be included in computing the interest in such payment.

4.       PREPAYMENT.

         Maker may prepay the Loan, in whole or in part, at any time without
         penalty or premium.

5.       LAWFUL MONEY.

         Principal and interest are payable in lawful money of the United States
         of America.

6.       APPLICATION OF PAYMENTS/LATE CHARGE/DEFAULT INTEREST.

         (a)      Absent the occurrence of an Event of Default hereunder, any
                  payments received by the holder hereof pursuant to the terms
                  hereof shall be applied first to sums, other than principal
                  and interest, due the holder hereof pursuant to this Note,
                  next to the payment of all interest accrued to the date of
                  such payment, and the balance, if any, to the payment of
                  principal. Any payments received by the holder hereof after
                  the occurrence of an Event of Default hereunder shall be
                  applied to the amounts specified in this Paragraph 6(a) in
                  such order as the holder hereof may, in its sole discretion,
                  elect.

         (b)      If any payment of interest and/or principal is not received by
                  the holder hereof when such payment is due, then in addition
                  to the remedies conferred upon the holder hereof pursuant to
                  Paragraph 9 hereof, the amount due and unpaid shall bear
                  interest at the Default Interest Rate, computed from the date
                  on which the amount was due and payable until paid.

7.       EVENT OF DEFAULT.

         The (i) default in the payment of principal or interest when due
         pursuant to the terms of this Note and (ii) any default under any other
         material loan agreement executed by Maker shall be deemed to be an
         event of default ("Event of Default") hereunder.

8.       REMEDIES.

         Upon the occurrence of an Event of Default, then at the option of the
         holder hereof, the entire balance of principal together with all
         accrued interest thereon, and all other amounts payable by Maker
         hereunder shall, without demand or notice, immediately become due and
         payable. Upon the occurrence of an Event of Default (and so long as
         such Event of Default shall continue), the entire balance of principal
         hereof, together with all accrued interest thereon, and any judgment
         for such principal, interest, and other amounts shall bear interest at
         the Default Interest Rate, subject to the limitations contained in
         Paragraph 13 hereof. No delay or omission on the part of the holder
         hereof in exercising any right under this Note hereof shall operate as
         a waiver of such right.

9.       WAIVER.

         Maker, endorsers, guarantors, and sureties of this Note hereby waive
         diligence, demand for payment, presentment for payment, protest, notice
         of nonpayment, notice of protest, notice of intent to accelerate,
         notice of acceleration, notice of dishonor, and notice of nonpayment,
         and all other notices or demands of any kind and expressly agree that,
         without in any way affecting the liability of Maker, endorsers,
         guarantors, or sureties, the holder hereof may extend any maturity date
         or the time for payment of any installment due hereunder, accept
         additional security, release any Person liable, and release any
         security or guaranty. Maker, endorsers, guarantors, and sureties waive,
         to the full extent permitted by law, the right to plead any and all
         statutes of limitations as a defense.

10.      CHANGE, DISCHARGE, TERMINATION, OR WAIVER.

         No provision of this Note may be changed, discharged, terminated, or
         waived except in a writing signed by the party against whom enforcement
         of the change, discharge, termination, or waiver is sought. No failure
         on the part of the holder hereof to exercise and no delay by the holder
         hereof in exercising any right or remedy under this Note or under the
         law shall operate as a waiver thereof.

11.      ATTORNEYS' FEES.

         If this Note is not paid when due or if any Event of Default occurs,
         Maker promises to pay all costs of enforcement and collection and
         preparation therefor, including but not limited to, reasonable
         attorneys' fees, whether or not any action or proceeding is brought to
         enforce the provisions hereof (including, without limitation, all such
         costs incurred in connection with any bankruptcy, receivership, or
         other court proceedings whether at the trial or appellate level).

12.      SEVERABILITY.

         If any provision of this Note is unenforceable, the enforceability of
         the other provisions shall not be affected and they shall remain in
         full force and effect.

13.      INTEREST RATE LIMITATION.

         Maker hereby agrees to pay an effective rate of interest that is the
         sum of the interest rate provided for herein, together with any
         additional rate of interest resulting from any other charges of
         interest or in the nature of interest paid or to be paid in connection
         with the Loan. Holder and Maker agree that none of the terms and
         provisions contained herein shall be construed to create a contract for
         the use, forbearance or detention of money requiring payment of
         interest at a rate in excess of the maximum interest rate permitted to
         be charged by the laws of the State of Arizona. In such event, if any
         holder of this Note shall collect monies which are deemed to constitute
         interest which would otherwise increase the effective interest rate on
         this Note to a rate in excess of the maximum rate permitted to be
         charged by the laws of the State of Arizona, all such sums deemed to
         constitute interest in excess of such maximum rate shall, at the option
         of the holder, be credited to the payment of other amounts payable
         hereunder or returned to Maker.

14.      NUMBER AND GENDER.

         In this Note the singular shall include the plural and the masculine
         shall include the feminine and neuter gender, and vice versa.

15.      HEADINGS.

         Headings at the beginning of each numbered section of this Note are
         intended solely for convenience and are not part of this Note.

16.      CHOICE OF LAW.

         THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
         LAWS OF THE STATE OF ARIZONA WITHOUT GIVING EFFECT TO CONFLICT OF LAWS
         PRINCIPLES.

17.      INTEGRATION.

         This Note contains the complete understanding and agreement of the
         holder hereof and Maker and supersede all prior representations,
         warranties, agreements, arrangements, understandings, and negotiations.

18.      BINDING EFFECT.

         This Note will be binding upon, and inure to the benefit of, the holder
         hereof, Maker, and their respective successors and assigns. Maker may

19.      TIME OF THE ESSENCE.

         Time is of the essence with regard to each provision hereof as to which
         time is a factor.

20.      SURVIVAL.

         The representations, warranties, and covenants of the Maker in this
         Note shall survive the execution and delivery of this Note and the
         making of the Loan.

21.      SUBORDINATION.

         Holder's rights to payment under this Note shall be at all times and in
         all respects wholly subordinate and inferior in claim and right to the
         obligations of Maker to the Banks, as that term is defined in that
         certain Credit Agreement between Maker and Banks, dated August 31,
         2000.
