conditions.

         NOW, THEREFORE, Landlords and Tenant, in consideration of the foregoing
premises and other good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, hereby agree as follows:

         1. Defined Terms. All capitalized terms used and not specifically
defined in this Amendment shall have the respective meanings assigned to those
terms in the Existing Leases. Wherever reference is made in a particular
Existing Lease to "the Lease", "this Lease", "herein", "hereof" or words of
similar import, it shall be deemed to refer to such Existing Lease, as amended
by this Amendment, and as the same may hereafter be amended, modified, extended,
supplemented, renewed, replaced or restated, in accordance with the terms
thereof.

         2. Amendments to Existing Lease. Landlords and Tenant agree that the
Existing Leases, effective as of the date of this Amendment, are hereby modified
and amended as follows:

                  a. The term of each of the Existing Leases is hereby extended
         for six (6) additional years, commencing November 1, 2006 and expiring
         October 31, 2012 (each an "Extended Lease Term"), unless sooner
         terminated pursuant to the terms and provisions of the respective
         Existing Leases, as amended by this Amendment, or applicable law or in
         equity. Accordingly, wherever reference is made in the Existing Leases,
         as amended by this Amendment, to the "Term", "Lease Term" or words of
         similar import, it shall be deemed to include the original lease term
         under the respective Existing Lease and the Extended Lease Term; and

                  b. (i) From November 1, 2006 through October 31, 2011, Base
         Rent or Basic Rent, as the case may be under the respective Existing
         Leases (hereinafter "Base Rent") for the Demised Premises shall be
         adjusted to an amount equal to the Base Rent in effect on October 31,
         2006 under the respective Existing Leases multiplied by the lesser of
         (A) 115%, and (B) the Cumulative CPI Factor (as hereinafter defined)
         for the period from November 1, 2001 through October 31, 2006 (the
         "First CPI Accumulation Period"). There shall be no decrease in the
         Base Rent as a result of the adjustment contemplated by this clause;
         and

                           (ii) From November 1, 2011 through October 31, 2012,
         Base Rent for the Demised Premises shall be adjusted to an amount equal
         to the Base Rent in effect on October 31, 2011 under the respective
         Existing Leases multiplied by the lesser of (A) 115%, and (B) the
         Cumulative CPI Factor for the period from November 1, 2006 through
         October 31, 2011 (the "Second CPI Accumulation Period"). There shall be
         no decrease in the Base Rent as a result of the adjustment contemplated
         by this clause.

                                       2

         As used in this subparagraph "Cumulative CPI Factor" shall mean a
         fraction, the numerator of which is the Current Number and the
         denominator of which is the Base Number. As used in this definition,
         the following capitalized terms shall mean: "Base Number" shall mean
         the Consumer Price Index for All Urban Consumers, United States City
         Average, All Items (1982-84=1 00), issued by the Bureau of Labor
         Statistics of the United States Department of Labor (hereinafter called
         the "Index") for the month immediately prior to (x) the First CPI
         Accumulation Period or (y) the Second CPI Accumulation Period, as
         applicable; and "Current Number" shall mean the latest Index published
         for the last month of (x) the First CPI Accumulation Period or (y) the
         Second CPI Accumulation Period, as applicable, by the Bureau of Labor
         Statistics or other governmental agency then publishing the Index (or
         if the Index is no longer published, the index of consumer prices
         reasonably deemed by the respective Landlord to be comparable to the
         Index), after making such adjustments as may be prescribed by the
         agency publishing the same or as otherwise so deemed to be required to
         compensate for changes subsequent to January 1, 1984 in the base, items
         included or method of compilation thereof.

         3. Governing Law; Severability. The laws of the State of Arizona shall
govern the validity, performance and enforcement of this Amendment. The
invalidity or unenforceability pursuant to applicable law of any provision of
this Amendment shall not affect or impair any other provision.

         4. Merger; No Oral Amendment. All negotiations, considerations,
representations and understandings between the parties with respect to the
amendment of the Existing Leases are incorporated in this Amendment. This
Amendment may not be amended, modified, or otherwise changed without the mutual
agreement in writing of the parties hereto.

         5. Successors and Assigns. This Amendment shall be binding upon and
inure to the benefit of the successors, legal representatives, heirs and assigns
of the parties hereto.

         6. Due Authorization; No Assignment Etc. Each of the persons executing
this Amendment on behalf of Tenant, hereby covenants and warrants that: Tenant
is a duly constituted corporation authorized to do business in the State of
Arizona; all franchise and corporate taxes of Tenant have been paid to date;
Tenant is duly authorized to execute and deliver this Amendment, and perform its
obligations under the Existing Leases, as amended by this Amendment; the
execution and delivery of this Amendment by Tenant, and the performance by
Tenant of its obligations under the Existing Leases, as amended by this
Amendment, do not violate or contravene in any manner any of the organizational
documents of, or agreements, instruments or documents entered into by, Tenant;
such persons are duly authorized to execute and deliver this Amendment on behalf
of Tenant, and no consent to the execution, delivery or performance of this
Amendment by each such person is required. Tenant represents that it has not
assigned any of the Existing Leases or sublet all or any portion of the Demised
Premises.

         7. Effectiveness. This Amendment shall become effective only upon
execution and delivery thereof by Landlords and Tenant. Except as expressly
amended by this Amendment, all

                                       3
<PAGE>
of the terms, covenants and conditions of the Existing Leases remain and shall
continue in full force and effect and are hereby ratified and confirmed.

         8. Conditional Limitation. This Amendment is conditioned upon there
existing no event which with or without the passage of time or the giving of
notice, or both, would constitute a default by Tenant under any of the Existing
Leases on the commencement of the Extended Lease Term. In the event that any
such default exists, at Landlords' option, to be exercised by written notice to
Tenant, this Amendment shall be null and void and of no further force or effect.

         9. Counterparts. This Amendment may be executed in two or more
counterpart copies of the entire document or of signature pages to the document,
each of which may be executed by one or more of the parties hereto, but all of
which, when taken together, shall constitute a single agreement binding upon all
of the parties hereto.

         IN WITNESS WHEREOF, Landlords and Tenant have executed and delivered
this Amendment as of the date first written above.

                                        LANDLORDS:
