terms used in this Note without definition shall have the respective meanings
set forth in the Agreement.

1.   INTEREST AND RATES AND PAYMENTS

     1.1 Stated Interest Rate. Except as provided in Section 1.2 below, the
principal balance outstanding hereunder shall bear interest, until fully paid,
at 6.0% per annum (the "Stated Interest Rate") based on the number of days
elapsed in a 365-day year.

     1.2 Default Interest Rate. The "Default Interest Rate" shall be the greater
of (a) 10.0% per annum, or (b) the prime rate as published in the Wall Street
Journal, plus 1.0%.

     1.3 Manner of Payment. All payments of principal and interest on this Note
shall be made to the address designated by Payee. If any payment of principal or
interest on this Note is due on a day that is not a Business Day, such payment
shall be due on the next succeeding

Business Day. "Business Day" means any day other than a Saturday, Sunday or
legal holiday in the State of Arizona.

     1.4 Prepayment. Maker may, without premium or penalty, at any time and from
time to time, prepay all or any portion of the outstanding principal balance due
under this Note, provided that each such prepayment is accompanied by accrued
interest on the amount of principal prepaid calculated to the date of such
prepayment. Any partial prepayments shall be applied to installments of
principal in inverse order of their maturity.

     1.5 Subordination. The indebtedness evidenced by this Note, including the
principal hereof and interest hereon, is expressly subordinate and subject in
right of payment to the prior payment in full of all "Senior Indebtedness,"
whether now outstanding or hereafter incurred. The term "Senior Indebtedness"
shall mean the principal of and premium, if any, and interest on (a)
indebtedness (other than this Note) of Maker for money borrowed from or
guaranteed to individuals or other persons, firms, or corporations that engage
in lending money, including, but without limitation, banks, trust companies,
insurance companies, and other financing institutions and charitable trusts,
pension trusts, and other investing organizations, evidenced by notes or similar
obligations; (b) indebtedness of Maker evidenced by notes or debentures (other
than this Note) issued under the provisions of an indenture or similar
instrument between Maker and a bank or trust company; and (c) indebtedness
incurred, assumed, or guaranteed by Maker in connection with the acquisition by
it or a subsidiary of any property or asset intended to be leased or sold to
others in the ordinary course of the business of Maker or such subsidiary;
unless, in each case, by the terms of the instrument creating or evidencing the
indebtedness it is expressly provided that such indebtedness is not superior in
right of payment to this Note.

2.   DEFAULTS

     2.1 Events of Default. The occurrence of any one or more of the following
events with respect to Maker shall constitute an event of default hereunder
("Event of Default"):

          (a) If Maker shall fail to pay when due any payment of principal or
interest on this Note and such failure continues for 15 days after Payee
notifies Maker thereof in writing.

          (b) If, pursuant to or within the meaning of the United States
Bankruptcy Code or any other federal or state law relating to insolvency or
relief of debtors (a "Bankruptcy Law"), Maker shall (i) commence a voluntary
case or proceeding; (ii) consent to the entry of an order for relief against it
in an involuntary case; (iii) consent to the appointment of a trustee, receiver,
assignee, liquidator, or similar official; (iv) make an assignment for the
benefit of its creditors; or (v) admit in writing its inability to pay its debts
as they become due.

          (c) If a court of competent jurisdiction enters an order or decree
under any Bankruptcy Law that (i) is for relief against Maker in an involuntary
case; (ii) appoints a trustee, receiver, assignee, liquidator, or similar
official for Maker or substantially all of Maker's properties; or (iii) orders
the liquidation of Maker, and in each case the order or decree is not dismissed
within 60 days.

<PAGE>

          (d) If Maker fails to comply with any provision contained in the
document delivered by Maker pursuant to Section 4.2(g) of the Agreement and such
failure continues for 15 days after Payee notifies Maker thereof in writing.

     2.2 Effect of Event of Default. The principal balance outstanding hereunder
from time to time shall bear interest at the Default Interest Rate from the date
of the occurrence of an "Event of Default" hereunder until the earlier of (a)
the date on which the principal balance outstanding hereunder, together with all
accrued interest and other amounts payable hereunder, is paid in full; or (b)
the date on which such Event of Default is timely cured.

     2.3 Remedies. Upon the occurrence of an Event of Default hereunder (unless
all Events of Default have been cured or waived by Payee), Payee may, at its
option (a) by written notice to Maker, declare the entire unpaid principal
balance of this Note, together with all accrued interest thereon, immediately
due and payable regardless of any prior forbearance and (b) exercise any and all
rights and remedies available to it under applicable law, including, without
limitation, the right to collect from Maker all sums due under this Note. Maker
shall pay all reasonable costs and expenses incurred by or on behalf of Payee in
connection with Payee's exercise of any or all of its rights and remedies under
this Note, including, without limitation, reasonable attorneys' fees.

3.   MISCELLANEOUS

     3.1 Waiver. The rights and remedies of Payee under this Note shall be
cumulative and not alternative. No waiver by Payee of any right or remedy under
this Note shall be effective unless in a writing signed by Payee. Neither the
failure nor any delay in exercising any right, power, or privilege under this
Note will operate as a waiver of such right, power, or privilege, and no single
or partial exercise of any such right, power, or privilege by Payee will
preclude any other or further exercise of such right, power, or privilege or the
exercise of any other right, power, or privilege. To the maximum extent
permitted by applicable law, (a) no claim or right of Payee arising out of this
Note can be discharged by Payee, in whole or in part, by a waiver or
renunciation of the claim or right unless in a writing signed by Payee; (b) no
waiver that may be given by Payee will be applicable except in the specific
instance for which it is given; and (c) no notice to or demand on Maker will be
deemed to be a waiver of any obligation of Maker or of the right of Payee to
take further action without notice or demand as provided in this Note.

     3.2 Time of the Essence. Time is of the essence of this Note and each and
every provision hereof.

     3.3 Amendments. No amendment, modification, change, waiver, release, or
discharge hereof and hereunder shall be effective unless evidenced by an
instrument in writing and signed by the party against whom enforcement is
sought.

     3.4 Notices. Any notice required or permitted to be given hereunder shall
be given in accordance with the notice provisions set forth in the Agreement.

     3.5 Severability. If any provision in this Note is held invalid or
unenforceable by any court of competent jurisdiction, the other provisions of
this Note will remain in full force and

                                       3
<PAGE>
effect. Any provision of this Note held invalid or unenforceable only in part or
degree will remain in full force and effect to the extent not held invalid or
unenforceable.

     3.6 Governing Law. This Note will be governed by and construed under the
laws of the State of Arizona without regard to conflicts-of-laws principles that
would require the application of any other law.

     3.7 Restrictions on Transfer. This Note shall not be assigned or
transferred by Payee without the express prior written consent of Maker. Subject
to the preceding sentence, this Note will be binding in all respects upon Maker
and inure to the benefit of Payee.

     3.8 Section Headings; Construction. The headings of Sections in this Note
are provided for convenience only and will not affect its construction or
interpretation. All references to "Section" or "Sections" refer to the
corresponding Section or Sections of this Note unless otherwise specified. All
words used in this Note will be construed to be of such gender or number as the

and "hereunder" and similar references refer to this Note in its entirety and
not to any specific section or subsection hereof, the words "including" or
