2. LEASED PREMISES: NO ADJUSTMENTS

     2.1 Leased Premises. Landlord leases to Tenant, and Tenant leases and
accepts from Landlord, the Leased Premises, upon the terms and conditions set
forth in this Lease and any modifications, supplements or addenda to this Lease
(the "Lease"), including the Basic Provisions of Article I which are
incorporated into this Lease by this reference, together with the nonexclusive
right to use, in common with Landlord and others, the Building Common Areas (as
defined below). For the purposes of this Lease, the term "Building Common Areas"
means common hallways, corridors, walkways and footpaths, foyers and lobbies,
bathrooms and janitorial closets, electrical and telephone closets, landscaped
areas, and such other areas within or adjacent to the Building which are subject
to or are designed or intended solely for the common enjoyment, use and/or
benefits of the tenants of the Building.

     2.2 No Adjustment The Annual Basic Rent at the Commencement Date (as
defined below) is based on the Leased Premises containing approximately the
rentable square footage set forth in Article 1.8 above. The Annual Basic Rent
shall not be increased or decreased if the actual rentable square footage of the
Leased Premises is more or less than the rentable square footage set forth in
Article 1.8.

3. LEASE TERM: COMMENCEMENT DATE

     3.1 Lease Term. The Lease Term shall begin on the Commencement Date and
shall be for the period set forth in Article 1.10 above, plus any period of less
than one (1) month between the Commencement Date and the first day of the next
succeeding calendar month, unless sooner terminated in accordance with the
further provisions of this Lease.

     3.2 Commencement Date. The Commencement Date shall mean the earliest of (a)
the date on which Landlord tenders possession of the Leased Premises to Tenant;
(b) the date on which Landlord would have tendered possession of the Leased
Premises to Tenant but for any act or omission of Tenant, its agents,
contractors or employees, or (c) the date on which Tenant takes possession of
the Leased Premises.

     3.3 Memorandum of Commencement Date. Landlord and Tenant shall, within ten
(10) days after the Commencement Date, execute a declaration in the form of
Exhibit "C" attached hereto specifying the Commencement Date should the
Commencement Date be a date other than the Scheduled Commencement Date.

     3.4 Delay in Commencement Date. In the event Landlord shall be unable, for
any reason, to deliver possession of the Leased Premises to Tenant on the
Scheduled Commencement Date, Landlord shall not be liable for any loss or damage
occasioned due to such failure, nor shall such inability affect the validity of
this Lease or the obligations of Tenant. In such event, Tenant shall not be
<PAGE>
obligated to pay Annual Basic Rent or Additional Rent until the Commencement
Date. In the event Landlord shall not have delivered possession of the Leased
Premises to Tenant within thirty (30) days after the Scheduled Commencement
Date, and if such failure to deliver possession was (a) caused solely by the
fault or neglect of Landlord, and (b) not caused by any fault or neglect of
Tenant or due to additional time required to plan for and install other work for
Tenant beyond the amount of time which would have been required if only building
standard improvements had been installed, then, as its sole and exclusive remedy
for Landlord's failure to deliver possession of the Leased Premises in a timely
manner, Tenant shall have the right to terminate this Lease by delivering
written notice of termination to Landlord at any time within thirty (30) days
after the expiration of such thirty (30) day period. Such termination shall be
effective thirty (30) days after receipt by Landlord of Tenant's notice of
termination unless Landlord shall, prior to the expiration of such thirty (30)
day period, deliver possession of the Leased Premises to Tenant. Upon a
termination of this Lease pursuant to the provisions of this Article 3.4, the
parties shall have no further obligations or liabilities to the other and
Landlord shall promptly return any monies previously deposited or paid by
Tenant.

     3.5 Lease Year. Each "Lease Year" shall be a period of twelve (12)
consecutive calendar months, the first Lease Year beginning on the Commencement
Date or on the first day of the calendar month next succeeding the Commencement
Date if the Commencement Date is not on the first day of a calendar month.

4. SECURITY DEPOSIT

     Tenant shall pay to Landlord, upon the execution of this Lease, the
Security Deposit set forth in Article 1.13 above as security for the performance
by Tenant of its obligations under this Lease, which amount shall be returned to
Tenant after the expiration or earlier termination of this Lease, provided that
Tenant shall have fully performed all of its obligations contained in this
Lease. The Security Deposit, at the election of Landlord, may be retained by
Landlord as and for its full damages or may be applied in reduction of any loss
and/or damage sustained by Landlord by reason of the occurrence of any breach,
nonperformance or default by Tenant under this Lease without the waiver of any
other right or remedy available to Landlord at law, in equity or under the terms
of this Lease. If any portion of the Security Deposit is so used or applied,
Tenant shall, within five(5) days after written notice from Landlord, deposit
with Landlord immediately available funds in an amount sufficient to restore the
Security Deposit to its original amount, and Tenant's failure to do so shall be
a breach of this Lease. Tenant acknowledges and agrees that in the event Tenant
shall file a voluntary petition pursuant to the Bankruptcy Code, or if an
involuntary petition is filed against Tenant pursuant to the Bankruptcy Code,
then Landlord may apply the Security Deposit towards those obligations of Tenant
to Landlord which accrued prior to the filing of such petition. Tenant
acknowledges further that the Security Deposit may be commingled with Landlord's
other funds and that Landlord shall be entitled to retain any interest earnings
on the Security Deposit. In the event of termination of Landlord's Interest in
this Lease, Landlord shall transfer the Security Deposit to Landlord's successor
in interest, and Landlord shall be released from liability by Tenant for the
return of such deposit or for an accounting of the Security Deposit.

5. RENT: RENT TAX: ADDITIONAL RENT

     5.1 Payment of Rent. Tenant shall pay to Landlord the Annual Basic Rent set
forth in Article 1.12 above, subject to adjustment as provided for in Article
1.12. The Annual Basic Rent shall be paid in equal monthly installments, on or
before the first day of each and every calendar month during the Lease Term, in
advance, without notice or demand and without abatement, deduction or set-off,
except for the first month's rent which is due and payable on execution, and
pro-rata, in advance for any partial month.. The Annual Basic Rent for the first
full month of the Lease Term shall be paid upon the execution of this Lease. All
payments requiring proration shall be prorated on the basis of a thirty (30) day
month. In addition, all payments to be made under this Lease shall be paid in
lawful money of the United States of America to Landlord or its agent at the
address set forth in Article 1.3 above, or to such other person or at such other
place as Landlord may from time to time designate in writing.

     5.2 Rent Tax. In addition to the Annual Basic Rent and Additional Rent (as
defined below), Tenant shall pay to Landlord, together with the monthly
installments of Annual Basic Rent and payments of Additional Rent, an amount
equal to any state or local sales, rental, occupancy, excise, use or
transactional privilege taxes assessed or levied upon Landlord with respect to
the amounts paid by Tenant to Landlord under this Lease, as well as all taxes
assessed or imposed upon Landlord's gross receipts or gross income from leasing
the Leased Premises to Tenant, including, without limitation, transaction
privilege taxes, education excise taxes, any tax now or subsequently imposed by
<PAGE>
the City of Phoenix, the State of Arizona, any other governmental body, and any
taxes assessed or imposed in lieu of or in substitution of any of the foregoing
taxes. Such taxes shall not, however, include any franchise, gift, estate,
inheritance, conveyance, transfer or net income tax assessed against Landlord.

     5.3 Additional Rent In addition to Annual Basic Rent, all other amounts to
be paid by Tenant to Landlord pursuant to this Lease (including amounts to be
paid by Tenant pursuant to Article 6 below), if any, shall be deemed to be
Additional Rent, irrespective of whether designated as such, and shall be due
and payable within thirty (30) days after receipt by Tenant of Landlord's
statement or together with the next succeeding installment of Annual Basic Rent,
whichever shall first occur. Landlord shall have the same remedies for the
failure to pay Additional Rent as for the nonpayment of Annual Basic Rent.

6. OPERATING COSTS

     6.1 Tenant's Obligation. The Annual Basic Rent does riot include amounts
attributable to any increase in the amount of Taxes (as hereinafter defined) or
amounts attributable to any increase in the cost of the use, management, repair,
service, insurance, condition, operation and maintenance of the Building.
Therefore, in order that the Annual Basic Rent payable throughout the Lease Term
shall reflect any such increases, Tenant shall pay to Landlord, in accordance
with the further provisions of this Article 6, an amount per rentable square
foot of the Leased Premises equal to the difference between the Operating Costs
(as hereinafter defined) per rentable square foot and the Base Year Costs.
Tenant acknowledges that the Base Year Costs does not constitute a
representation by Landlord as to the Operating Costs per rentable square foot
that may be incurred during any calendar year.

     6.2 Landlord's Estimate. Landlord shall furnish Tenant an estimate of the
Operating Costs per rentable square foot for each Fiscal Year (as hereinafter
defined) commencing with the Fiscal Year in which the Commencement Date occurs.
In addition, Landlord may, from time to time, furnish Tenant a revised estimate
of Operating Costs should Landlord anticipate any increase in Operating Costs
from that set forth in a prior estimate. Commencing with the first month to
which an estimate applies, Tenant shall pay, in addition to the monthly
installments of Annual Basic Rent, an amount equal to one-twelfth (1/12th) of
the product of the rentable square footage of the Leased Premises multiplied by
the difference (but not less than zero (0)), if any, between such estimate and
the Base Year Costs; provided, however, if less than ninety-five percent (95%)
of the rentable area of the Building shall be occupied by tenants during the
period covered by such estimate, the estimated Operating Costs for such period
shall be, for the purposes of this Article 6, increased to an amount reasonably
determined by Landlord to be equivalent to the Operating Costs that would be
incurred if occupancy would be at least ninety-five percent (95%) during the
entire period. Within one hundred twenty (120) days after the expiration of each
Fiscal Year or such longer period of time as may be necessary to compile such
statement, Landlord shall deliver to Tenant a statement of the actual Operating
Costs for such Fiscal Year, If the actual Operating Costs for such Fiscal Year
are more or less than the estimated Operating Costs, a proper adjustment shall
be made; provided, however, if less than ninety-five percent (95%) of the
rentable area of the Building shall have been occupied by tenants at any time
during such period, the actual Operating Costs for such period shall be, for the
purposes of this Article 6, increased to an amount reasonably determined by
Landlord to be equivalent to the Operating Costs that would have been incurred
had such occupancy been at least ninety-five (95%) during the entire period. Any
excess amounts paid by Tenant shall be, at Landlord's option, applied to any
amounts then payable by Tenant to Landlord or to the next maturing monthly
installments of Annual Basic Rent or Additional Rent. Any deficiency between the
estimated and actual Operating Costs shall be paid by Tenant to Landlord
concurrently with the monthly installment of Annual Basic Rent next due. Any
amount owing for a fractional Fiscal Year in the first or final Lease Years of
the Lease Term shall be prorated. For the purposes of this Lease, the term means
the fiscal year (or portion of the fiscal year) of Landlord. The Fiscal Year
currently commences on January land ends on December 31; provided, however,
Landlord reserves the right to change the Fiscal Year at any time or times, but
no such change shall result in an increase in the amounts otherwise payable by
Tenant pursuant to the provisions of this Article 6.

     6.3 Operating Costs - Defined. For the purposes of this Lease, "Operating
Costs" shall mean all costs and expenses accrued, paid or incurred by Landlord,
or on Landlord's behalf, in respect of the use, management, repair. service,
insurance, condition, operation and maintenance of the Building including, but
not limited to the following: (a) salaries, wages and benefits of all persons
who perform duties in connection with landscaping, parking, janitorial and

prohibitions shall apply to each successive transfer, assignment or subletting
under this Article 19, if any.

     19.2 Deemed Transfers. If Tenant is a corporation, an unincorporated
association, a limited liability company or a partnership, the transfer,

sublet all or any part of the Leased Premises, Landlord may, at its option, upon
written notice to Tenant within thirty (30) days after Landlord's receipt of the

termination date with respect to the Leased Premises or the recaptured portion
of the Leased Premises, and prorating the Annual Basic Rent, Additional Rent and
other charges payable under this Lease to such date. If Landlord doe not elect
to recapture as set forth above, Tenant may then after enter into a valid
assignment or sublease with respect to the Leased Premises, provided that

Lease or sublets the Leased Premises, the Annual Basic Rent set forth in Article
1.12 above, as adjusted, shall be increased effective as of the date of such
assignment or subletting to the rent and other consideration payable by any such
assignee or sublessee pursuant to such assignment or sublease. Notwithstanding
the foregoing, in no event shall the Annual Basic Rent after any such assignment

above, as adjusted.

     19.6 No Release from Liability. Landlord may collect Annual Basic Rent and
Additional Rent from the assignee, subtenant, occupant or other transferee, and
apply the amount so collected, first to the monthly installments of Annual Basic
Rent, then to any Additional Rent and other sums due and payable to Landlord,
and the balance, if any, to Landlord, but no such assignment, subletting,
occupancy, transfer or collection shall be deemed a waiver of Landlord's rights
under this Article 19, or the acceptance of the proposed assignee, subtenant,
occupant or transferee. Notwithstanding any assignment, sublease or other
transfer (with or without the consent of Landlord), Tenant shall remain
primarily liable under this Lease and neither Tenant nor any Guarantor shall be
released from performance of any of the terms, covenants and conditions of this

such Successor Landlord as Tenant's landlord under this Lease and shall promptly
execute and deliver any instrument that such Successor Landlord may reasonably
request to evidence such attornment. Notwithstanding such subordination,

and perform all of the provisions of this Rental Agreement, unless this Rental
Agreement is otherwise terminated pursuant to its terms.
