                           Lenders in amounts that cause the outstanding
                           balance of the aggregate Revolving Loans then
                           outstanding, after giving effect to such Revolving
                           Loan, to exceed the amount equal to the Borrowing
                           Base less Availability Reserves, in each case then
                           in effect at such time (any such excess Revolving
                           Loan is herein referred to collectively as an
                           "Overadvance" and collectively, the "Overadvances");
                           provided, however (i) no such event or occurrence
                           shall cause or constitute a waiver of the
                           Administrative Agent's or any Lender's right to
                           refuse to make any further Overadvance, or to make
                           any Revolving Loans or Term Loans in accordance with
                           this Agreement and the other Loan Documents, and
                           (ii) no Overadvance shall result in a Default or
                           Event of Default due to Borrower's failure to comply
                           with Section 2.7(d), but solely with respect to the
                           amount of such Overadvance. Overadvances may be made
                           notwithstanding the condition set forth in Section
                           3.2(c)(i). All Overadvances shall bear interest at
                           the rates and be payable on the dates set forth in
                           Section 2.8. Any Overadvance made pursuant to this
                           Section 2.1(c) shall be repaid on the Revolving
                           Credit Termination Date. The authority of the
                           Administrative Agent to make Overadvances is limited
                           to an aggregate principal amount not to exceed
                           $130,000,000 at any time outstanding and shall not
                           cause the aggregate principal amount of the
                           Revolving Loan outstanding at any time to exceed the
                           Revolving Credit Commitment."

                           (c)      Section 2.2(a)(i) is hereby deleted and
         replaced with the following:

                                    "(i) whether the proposed Borrowing consists
                           of a Revolving Loan, a Term Loan or both and if the
                           Borrowing of Revolving Loans constitutes a request
                           for an Overadvance, the intended use of the proceeds
                           thereof,"

                           (d)      The first sentence of Section 2.6(a) is
         hereby deleted and replaced with the following:

                           "The Borrower may, upon at least one Business Day's
                           prior notice to the Administrative Agent, prepay the
                           outstanding principal amount of the Loans in whole or
                           in part; provided, however, that each partial
                           prepayment of Loans shall be in an aggregate
                           principal amount not less than $100,000; provided
                           further that all prepayments of the Revolving Loans
                           shall first be applied to Overadvances then
                           outstanding."

                           (e)      Section 2.7(d) is hereby deleted and
         replaced with the following:

                                    "(d) If, at any time, the aggregate
                           principal amount of the aggregate Revolving Loans
                           then outstanding (excluding Overadvances) exceeds by
                           more than $10,000,000 the amount equal to the
                           Borrowing Base less Availability Reserves, in each
                           case then in effect at such time, the Borrower shall
                           forthwith prepay the Revolving Loans then outstanding
                           in an amount equal to such excess. Overadvances made
                           pursuant to Section 2.1(c) shall be repaid on the
                           Revolving Credit Termination Date. If, at any time,
                           the aggregate principal amount of the aggregate
                           Revolving Loans (including Overadvances) exceeds the
                           aggregate Revolving Credit Commitments, the Borrower
                           shall forthwith prepay the Revolving Loans then
                           outstanding in an amount equal to such excess. If, at
                           any time, the aggregate principal amount of the
                           aggregate Term Loans exceeds the aggregate Term
                           Credit Commitments, the Borrower shall forthwith
                           prepay the Term Loans then outstanding in an amount
                           equal to such excess."

                           (f)      Section 2.7 is hereby amended by adding the
         following new paragraph as Section 2.7(e):

                                    "(e) Notwithstanding anything to the
                           contrary set forth in Section 2.7, except with
                           respect to the first sentence of Section 2.7(d), any
                           payments of the Revolving Loans pursuant to this
                           Section 2.7 shall first be applied to Overadvances
                           then outstanding."

                           (g)      Section 2.9(b) is hereby deleted and
         replaced with the following:

                                    "(b) The Borrower agrees to pay to the
                           Administrative Agent an arrangement fee equal to four
                           percent (4%) of the Original Commitment and two
                           percent (2%) of the Incremental Commitment
                           (collectively, the "Arrangement Fee"), payable on the
                           date of the funding of each Borrowing; provided,
                           however, that the Arrangement Fee shall only be
                           payable on that portion of such Borrowing equal to
                           the amount (if any) by which (i) the total
                           outstanding amount of the Loans (after giving effect
                           to the Borrowing) on the date of such Borrowing,
                           exceeds (ii) the maximum amount of the Loans
                           outstanding on any date prior to the date of such
                           Borrowing; provided further that all Borrowings
                           outstanding at any time up to $200 million shall be
                           deemed to be Borrowings of the Original Commitment
                           and; provided further, that in the event that

         2.1 Leased Premises.

                  (a) Landlord hereby leases to Tenant, and Tenant hereby leases
and accepts from Landlord, the Leased Premises, upon the terms and conditions
set forth in this Lease and any modifications, supplements or addenda hereto
(the "Lease"), including the Basic Provisions of Article 1 which are
incorporated herein by this reference, together with the nonexclusive right to
use, in common with Landlord and others, the Building Common Areas (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.

                  (b) Landlord hereby also grants Tenant the right to occupy
Suite 243 of the Building containing 1,896 rentable square feet (1,723 usable
square feet) commencing on the date on which Landlord notifies Tenant that
Landlord has completed repainting and recarpeting Suite 243 and terminating
December 31, 1997. The rental rate for Suite 243 shall be Eighteen and No/100
Dollars ($18.00) per rentable square foot and Tenant shall accept Suite 243 in
its "as is" condition

                                       2
<PAGE>   5

on the date Landlord tenders possession of Suite 243 to Tenant. Tenant's
occupancy of Suite 243 shall otherwise be subject to all of the terms and
conditions of this Lease.

         2.2 Adjustments. The Annual Basic Rent at the Commencement Date (as
hereinafter defined) is based on the Leased Premises containing the rentable
square footage set forth in Article 1.8 above, which square footage has been
precisely determined by Landlord and approved by Tenant prior to the date of the
Lease. No adjustments to Annual Basic Rent or any other charge shall be made if
the actual size of the Leased Premises is greater or smaller than that set forth
in Article 1.8. For the purpose of this Lease, Landlord and Tenant agree that
the useable square footage of the Leased Premises is 50,950.

                        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 date set
forth in Article 1.11 above.

         3.3 Intentionally Omitted.

         3.4 Quiet Possession. So long as there is not in existence an Event of
Default, Tenant may quietly have, hold and enjoy the Leased Premises during the
Lease Term, without hindrance or molestation by Landlord, subject, however, to
the matters referred to in Article 21. The provisions of this Article 3.4 shall
not extend to any disturbance, act or condition brought about by any tenant in
the Building.

         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. Each
Lease Year after the first Lease Year shall begin on the calendar day next
succeeding the expiration of the immediately preceding Lease Year.

                               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 within thirty (30) days 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 (which notice shall include an accounting of all
applications of all or any part of the Security Deposit), 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 any successor
thereto, or if an involuntary petition is filed against Tenant pursuant to the
Bankruptcy Code or any successor thereto, 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 thereon. In the event of termination of
Landlord's interest in this Lease, Landlord shall transfer the Security Deposit
to Landlord's successor in interest, whereupon Landlord shall be released from
liability by Tenant for the return of such deposit or the accounting therefore.

                       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 herein.
Notwithstanding any provision of this Lease to the contrary, Tenant shall pay to
Landlord the Annual Basic Rent with respect to 45,118 rentable square feet
(Suite 120) from and after the Commencement Date, Annual Basic Rent with respect
to 5,671 rentable square feet (part of Suite 200) from and after 5/18/96 and
shall pay the Annual Basic Rent with respect to the remaining 5,256 rentable
square feet (Suites 225 and 240) from and after the completion of the Tenant
Improvements described on Exhibit "H". Landlord and Tenant acknowledge and agree
that time is of the essence with respect to their respective obligations as set
forth in Exhibit "H" and Tenant shall use its best efforts to cooperate with
Landlord with respect to the completion of the Tenant Improvements. 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. If the
Commencement Date is other than the first day of a calendar month, the payment
for the partial month following the Commencement Date shall be prorated and
shall be payable on the first day of the first full calendar month of the Lease
Term. 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,
Tenant shall pay to Landlord, together with the monthly installments of Annual
Basic Rent and payments of Additional Rent, an amount equal to any governmental
taxes, including, without limitation, any sales, rental, occupancy, excise, use
or transactional privilege taxes assessed or levied upon Landlord with respect
to the amounts paid by Tenant to Landlord hereunder, 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 hereafter imposed by 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 and parking charges to
be paid by Tenant pursuant to Exhibits "E", "F" and "G"), if any, shall be
deemed to be Additional Rent, whether or not designated as such, and shall be
due and payable within five (5) 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 not include amounts
attributable to any increase in the amount of Taxes (defined below) or amounts
attributable to any increase in the cost of the management, repair, service,
insurance, operation and maintenance of the Building and the Property.
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 do not constitute a representation
by Landlord as to the Operating Costs per rentable square foot that may be
incurred during any subsequent calendar year.

         6.2 Landlord's Estimate. Landlord shall furnish Tenant an estimate of
the Operating Costs per rentable square foot for each calendar year commencing
with the 1997 calendar year. 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 January 1, 1997, 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

                                       4
<PAGE>   7

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
calendar 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 calendar year. If the actual Operating Costs for such calendar
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 refunded to Tenant with such statement
or, at Landlord's option, may be applied to any amounts then payable by Tenant
to Landlord or to the next maturing monthly installment of Annual Basic Rent or
Additional Rent. Any deficiency between the estimated and actual Operating Costs
shall be paid by Tenant to Landlord within thirty (30) days after receipt by
Tenant of notice of a deficiency. Any amount owing for a fractional calendar
year in the first or final Lease Years of the Lease Term shall be prorated.

         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 management, repair,
service, insurance, operation and maintenance of the Building and the Property,
including but not limited to the following:

limitation, all parking areas, service areas, walkways and landscaping;

however, that any such costs shall be amortized with interest over the useful
life of the alteration or improvement in accordance with generally accepted
accounting principles, such interest to accrue at a rate equal to the "prime

of the rentable square footage of the Building;

                  (p) The cost of any capital improvements or additions which
are intended to enhance the safety of the Property or reduce (or avoid increases

reasonable legal, accounting and other professional fees and expenses;

         7.1 Condition. The respective obligations of Landlord and Tenant with

and/or contractor(s) for such alterations and/or improvements and the materials
used in connection with such alterations, including, without limitation, paint,

the plans and specifications for the contemplated work and shall identify the
contractor(s) selected by Tenant to perform such work. Landlord may require that

Landlord's direction, but at the expense of Tenant, provided that in such event
Landlord shall complete such work at a cost and on a schedule that is
competitive with the cost and schedule proposed by contractor(s) selected by
Tenant to perform the work and Landlord may, as a condition to consenting to
work costing in excess of Fifteen Thousand and No/100 Dollars ($15,000.00),
require that Tenant provide security adequate in Landlord's judgment so that the
improvements or other alterations to the Leased Premises will be completed in a
good, workmanlike and lien free manner. Landlord may also require that any work
done to the interior of the Leased Premises be subject to the supervision of a
third party under contract to Landlord, and Tenant shall pay to Landlord, upon
completion of such work, a supervision fee in an amount equal to the actual cost
of such supervision, not to exceed, however, five percent (5%) of the cost of
such work. All such improvements or alterations must conform to and be in
substantial accordance in quality and appearance with the quality and appearance
of the improvements in the remainder of the Building. All such improvements
shall be the property of Landlord. In the event Landlord consents to the use by
Tenant of its own architect

                                       7
<PAGE>   10

and/or contractor for the installation of any such alterations or improvements,

and property damage insurance (naming Landlord as an additional insured) in a
form and in an amount approved by Landlord, and evidence that Tenant's architect
and/or contractor has procured the necessary permits, certificates and approvals
from the appropriate governmental authorities. Tenant acknowledges and agrees
that any review by Landlord of Tenant's plans and specifications and/or right of
approval exercised by Landlord with respect to Tenant's architect and/or
contractor is for Landlord's benefit only and Landlord shall not, by virtue of
such review or right of approval, be deemed to make any representation, warranty
or acknowledgment to Tenant or to any other person or entity as to the adequacy

reputation of Tenant's architect and/or contractor.

the cost of all repairs to the Leased Premises not required to be made by
Landlord and shall be responsible for any redecorating, remodeling, alteration
and painting during the Lease Term as Tenant deems necessary. Tenant shall pay

repairs to the exterior walls, exterior doors, roof, windows and corridors of
the Building, (b) keep the Building and the Building Common Areas in a clean,
neat and attractive condition, and (c) keep the Building equipment such as

service unless (i) the cause of the disruption is within Landlord's reasonable
control and is due to Landlord's negligence, and (ii) such disruption has a
material adverse affect on Tenant's business.

         7.5 Removal of Alterations. Upon the expiration or earlier termination
of this Lease, Tenant shall remove from the Leased Premises all movable trade
fixtures and other movable personal property, and shall promptly repair any
damage to the Leased Premises, the Building and/or the Property caused by such

of the Lease Term or immediately upon any termination of this Lease, Landlord
may require that Tenant remove from the Leased Premises any alterations,
additions, improvements, trade fixtures, equipment, shelving, cabinet units or
movable furniture (and other personal property) designated by Landlord to be
removed. In such event, Tenant shall, in accordance with the provisions of
Article 7.2 above, complete such removal (including the repair of any damage
caused thereby) entirely at its own expense and within fifteen (15) days after
notice from Landlord. All repairs required of tenant pursuant to the provisions
of this Article 7.5 shall be performed in a manner satisfactory to Landlord, and
shall include, but not be limited to, repairing plumbing, electrical wiring and
holes in walls, restoring damaged floor and/or ceiling tiles, repairing any
other cosmetic damage, and cleaning the Leased Premises.

         7.6 No Abatement. Except as provided herein, Landlord shall have no
liability to Tenant, nor shall Tenant's covenants and obligations under this
Lease, including without limitation, Tenant's obligation to pay Annual Basic
Rent and Additional Rent, be reduced or abated in any manner whatsoever by
reason of any inconvenience, annoyance, interruption or injury to business
arising from Landlord's making any repairs or changes which Landlord is required
or permitted to make pursuant to the terms of this Lease or by any other
tenant's Lease or are required by law to be made in and to any portion of the
Leased Premises, the Building or the Property. Landlord shall, nevertheless, use

insurance carrier, then any loss or damage which Landlord shall sustain by
reason thereof shall be borne by Tenant, and shall be paid by Tenant within five
(5) days after receipt of a bill therefor.

Article 16.1 below.

                  (c) Tenant's right to self-insure and to continue to
self-insure is conditioned upon and subject to:

         applied, of at least One Hundred Million Dollars ($100,000,000.00).

                                       11
<PAGE>   14

         the required level (such as the bankruptcy of Tenant), in which event

                  (d) In the event that Tenant elects to self-insure and an
event or claim occurs for which a defense and/or coverage would have been
available from the insurance company Tenant shall:

                           (i) undertake the defense of any such claim,
         including a defense of Landlord, at Tenant's sole cost and expense, and

                           (ii) use its own funds to pay any claim or replace
         any property or otherwise provide the funding which would have been
         available from insurance proceeds but for such election by Tenant to

                  (e) In the event Tenant has the right and elects that it will
not operate its business in the Leased Premises after the Leased Premises are
damaged or destroyed, Landlord shall have the right to determine that the
self-insurance proceeds either be paid to Landlord:

         accordance with Article 10 below and Tenant's liability and obligations

                  (a) (i) Within sixty (60) days after a partial destruction of
either the Leased Premises, the Building, or the Property (as defined in Article
10.1(f)), subject to Force Majeure and provided there is not then in existence

Landlord's notice, written notice of termination, which termination shall be

Landlord with notice of termination within the thirty (30) day period, Landlord
shall thereafter promptly commence the repair, reconstruction and restoration of
the Leased Premises, the Building or the Property, as applicable, and shall
diligently prosecute the same until completion. If Landlord shall not have
completed reconstruction of the Leased Premises, Building or Property, as
applicable, on or before the Completion Date, Tenant shall have the right, as
its sole and exclusive remedy, to terminate this Lease by delivering to
Landlord, within thirty (30) days after the Completion Date, written notice of
termination, which termination shall be effective thirty (30) days after receipt
by Landlord of Tenant's notice of termination unless Landlord shall have
completed such repairs and restoration prior to the expiration of such thirty
(30) day period. In the event that Tenant shall have given Landlord notice of
termination and Landlord shall not have completed reconstruction of the Leased
Premises, Building or Property prior to the expiration of the thirty (30) day
period, Tenant shall have the right to continue to occupy the Leased Premises
(but only to the extent of such occupancy as of the date Tenant delivers to
Landlord such notice of termination) for a period of ninety (90) days after the
end of such thirty (30) day period at the Annual Basic Rent then in effect under
Article 1.12 and such

                                       12

occupancy shall not be deemed a holdover. The failure of Tenant to terminate
this Lease pursuant to this Article 1O.1(a)(ii) shall be deemed a waiver by
Tenant of its right to terminate this Lease on account of the failure of
Landlord to complete the reconstruction by the Completion Date.

                  (b) (i) Within sixty (60) days after destruction of more than
thirty-three and one-third percent (33.33%) of the then full replacement cost of
the Leased Premises, the Building, or the Property as of the date of
destruction, subject to Force Majeure and provided there is not then in
existence an Event of Default, Landlord shall notify Tenant in writing of the
date by which Landlord estimates in good faith that reconstruction of the
Premises shall be complete (the "Completion Date"). If the Completion Date is
more than three hundred and thirty-five (335) days after the end of the sixty
(60) day period. Tenant shall have the right, as its sole and exclusive remedy,
to terminate this Lease by delivering to Landlord, within thirty (30) days after
receipt by Tenant of Landlord's notice, written notice of termination, which
termination shall be effective thirty (30) days after the end of the sixty (60)
day period. Failure by Tenant to terminate this Lease within such thirty (30)
day period shall be deemed a waiver by Tenant of such termination right.

                           (ii) In the event that Tenant shall not have provided
Landlord with notice of termination within the thirty (30) day period, Landlord
shall thereafter promptly commence the repair, reconstruction and restoration of
the Leased Premises, the Building or the Property, as applicable, and shall
diligently prosecute the same until completion. If Landlord shall not have
completed reconstruction of the Leased Premises, Building or Property, as
applicable, on or before the Completion Date, Tenant shall have the right, as
its sole and exclusive remedy, to terminate this Lease by delivering to
Landlord, within thirty (30) days after the Completion Date, written notice of
termination, which termination shall be effective thirty (30) days after receipt
by Landlord of Tenant's notice of termination unless Landlord shall have
completed such repairs and restoration prior to the expiration of such thirty
(30) day period. In the event that Tenant shall have given Landlord notice of
termination and Landlord shall not have completed reconstruction of the Leased
Premises, Building or Property prior to the expiration of the thirty (30) day
period, Tenant shall have the right to continue to occupy the Leased Premises
(but only to the extent of such occupancy as of the date Tenant delivers to
Landlord such notice of termination) for a period of ninety (90) days after the
end of such thirty (30) day period at the Annual Basic Rent then in effect under
Article 1.12 and such occupancy shall not be deemed a holdover. The failure of
Tenant to terminate this Lease pursuant to the previous sentence shall be deemed
a waiver by Tenant of its right to terminate this Lease on account of the
failure of Landlord to complete the reconstruction by the Completion Date.

                  (c) In the event of destruction of more than thirty-three and
one-third percent (33.33%) of the then full replacement cost of the Leased
Premises the Building, or the Property as of the date of destruction during the
last two (2) years of the Lease Term, Landlord and Tenant shall each have the
option to terminate this Lease upon giving written notice to the other party
within sixty (60) days after such destruction, which termination shall be
effective thirty (30) days after receipt of notice by the non-terminating party.

                  (d) In the event of a partial destruction of either the Leased
Premises, the Building, or the Property during the last one (1) year of the
Lease Term, Landlord and Tenant shall each have the option to terminate this
Lease upon giving written notice to the other party within sixty (60) days after
such destruction, which termination shall be effective thirty (30) days after
receipt of notice by the non-terminating party.

                  (e) In the event that Landlord shall exercise its right of
termination as set forth in Article 10.1(c) and 10.1(d) above, Tenant shall have
the right to nullify such election by Landlord by notifying Landlord within
thirty (30) days after receipt by Tenant of Landlord's notice of termination
that Tenant has exercised the right to extend this Lease as described in Rider 1
hereto; Tenant shall have the right to nullify Landlord's termination in such
circumstances at any time during the Lease Term.

                  (f) For purposes of this Article 10, "partial destruction"
shall be deemed destruction to an extent of thirty-three and one-third percent
(33.33%) or less of the then full replacement cost of the Leased Premises, the
Building, or the Property as of the date of destruction.

         10.2 Intentionally Omitted.

         10.3 Reconstruction. In the event of any reconstruction of the Leased
Premises, the Building or the Property pursuant to this Article 10, such
reconstruction shall be in conformity with all city, county, state and federal
ordinances, rules and regulations then in existence, as the same may

                                       13
<PAGE>   16

be interpreted and enforced. Notwithstanding that all reconstruction work shall
be performed by Landlord's contractor unless Landlord shall otherwise agree in
writing, Landlord's obligation to reconstruct the Leased Premises shall be only
to the comparable condition of the Leased Premises immediately prior to the
Commencement Date. Landlord's obligation to repair and reconstruct the Leased
Premises shall be limited to the amount of net proceeds of insurance received by
Landlord. Any extra expenses incurred by Landlord in the reconstruction of the
Leased Premises, the Building or any other portion of the Property as a result
of the violation by Tenant of the terms and conditions set forth in Article 34
below shall be borne by Tenant. Tenant, at Tenant's sole cost and expense, shall
be responsible for the repair and restoration of all items of the Tenant
improvements or Tenant's improvements and/or alterations installed pursuant to
Article 7.2 and the replacement of Tenant's stock in trade, trade fixtures,
furniture, furnishings and equipment. Tenant shall commence the installation of
fixtures, equipment and merchandise promptly upon delivery to Tenant of
possession of the Leased Premises and shall diligently prosecute such
installation to completion.

         10.4 Termination. Upon any termination of this Lease under any of the
provisions of this Article 10, Landlord and Tenant each shall be released
without further obligations to the other coincident with the surrender of
possession of the Leased Premises to Landlord, except for items which have
previously accrued and remain unpaid and provided that Landlord shall return to
Tenant the Security Deposit in accordance with the provisions of Article 4 and
any advance rent paid by Tenant to Landlord. In the event of termination, all
proceeds from Tenant's property insurance coverage and covering the Tenant
Improvements or Tenant's improvements and/or alterations installed pursuant to
Article 7.2. but excluding proceeds for trade fixtures, merchandise, signs and
other removable personal property, shall be disbursed and paid to Landlord.

         10.5 Abatement. In the event of repair, reconstruction and restoration
of the Leased Premises, the Minimum Annual Rental and Additional Rent shall be
abated proportionately with the degree to which Tenant's use of the Leased
Premises is impaired commencing from the date of destruction and continuing
during the period of such repair, reconstruction or restoration, Tenant shall
continue the operation of Tenant's business at the Leased Premises during any
such period to the extent reasonably practicable from the standpoint of prudent
business management Tenant shall not be entitled to any compensation or damages
from Landlord for loss of the use of the whole or any part of the Leased
Premises, or the building of which the Leased Premises are a part, Tenant's
personal property or for any inconvenience or annoyance occasioned by such
damage, repair, reconstruction or restoration.

         10.6 Waiver. Tenant hereby waives any statutory and common law rights
of termination which may arise by reason of any partial or total destruction of
the Leased Premises which Landlord is obligated to restore or may restore under
any of the provisions of this Lease, including the provisions of A.R.S. Section
33-343.

                            11. WAIVER OF SUBROGATION

         Tenant hereby waives its rights and the subrogation rights of its
insurer against Landlord and any other tenants of space in the Building or the
Property, as well as their respective members, officers, employees, agents,
authorized representatives and invitees, with respect to any claims including,
but not limited to, claims for injury to any persons, and/or damage to the
Leased Premises and/or any fixtures, equipment, personal property, furniture,
improvements and/or alterations in or to the Leased Premises, which are caused
by or result from (a) risks or damages required to be insured against wider this
Lease, or (b) risks and damages which are insured against by insurance policies
maintained by Tenant from time to time. Tenant shall obtain for Landlord from
its insurers under each policy required by this Lease a waiver of all rights of
subrogation which such insurers of Tenant might otherwise have against Landlord.

               12. LANDLORD'S RIGHT TO PERFORM TENANT OBLIGATIONS

         All covenants and agreements to be performed by Tenant under any of the
terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense and without any abatement of Annual Basic Rent or Additional Rent. If
Tenant shall fail to pay any sum of money, other than Annual Basic Rent,
required to be paid by it hereunder, or shall fail to perform any other act on
its part to be performed hereunder, and such failure shall continue for five (5)
days after written notice thereof by Landlord (or such shorter period of time as
may be reasonable under the circumstances in the event of an emergency following
oral notice to Tenant's senior management personnel in the Leased Premises),
Landlord may (but shall not be obligated to do so) without waiving or releasing

                                       14
<PAGE>   17
Tenant from any of Tenant's obligations, make any such payment or perform any
such other act on behalf of Tenant; provided, however, that Landlord shall not
perform any obligation of Tenant if Tenant shall have commenced curing such
failure and is diligently and in good faith prosecuting the same. All sums so
paid by Landlord and all necessary incidental costs, together with interest
thereon at the greater of (a) eighteen percent (18%) per annum or (b) the rate
of interest per annum publicly announced, quoted or published, from time to
time, by Bank One, Arizona, NA. at its Phoenix, Arizona office as its reference
rate" plus four (4) percentage points, from the date of such payment by Landlord
until reimbursement in full by Tenant (the "Default Rate"), shall be payable to
Landlord as Additional Rent with the next monthly installment of Annual Basic
Rent; provided, however, in no event shall the Default Rate exceed the maximum
rate (if any) permitted by applicable law.

                            13. DEFAULT AND REMEDIES

         13.1 Event of Default. The occurrence of any one or more of the
following events will constitute an "Event of Default" on the part of Tenant:

                  (a) Failure to pay any installment of Annual Basic Rent, any

(15) days (or such shorter period of time as may be specified by Landlord in the
event of an emergency, i.e., immediate danger to persons or property) after
written notice thereof by Landlord to Tenant, provided that if such default is
other than the payment of money and cannot be cured within such fifteen (15) day
period, then an Event of Default shall not have occurred if Tenant, within such
fifteen (15) day period, commences curing of such failure and diligently in good
faith prosecutes the same to completion and furnishes evidence thereof to
Landlord within thirty (30) days thereafter;

                  (c) If any warranty, representation or statement made by
Tenant to Landlord in connection with the financial statements of Tenant

                  (e) Failure to conduct substantially all business operations
within the Leased Premises for ten (10) consecutive days except for temporary

however, that in no event shall any such temporary closure exceed ninety (90)
days;

                  (f) If Tenant makes a bulk sale of its goods or moves or
commences, attempts to move its goods, equipment and personal property out of

                  (h) The filing of any petition by or against Tenant or any

modify Tenant's or any Guarantor's debts or obligations, which petition is not
discharged within sixty (60) days after the date of filing;

                  (i) The filing of any petition or other action taken to
reorganize or modify Tenant's or any Guarantor's capital structure, which
petition is not discharged within sixty (60) days after the date of filing

                  (j) If Tenant or any Guarantor shell be declared insolvent

                  (n) The occurrence of an Event of Default under Articles 31 or
34.11.

         13.2 Remedies. Upon the occurrence of an Event of Default, Landlord
may, without prejudice to any other rights and remedies available to a landlord
at law, in equity or by statute, Landlord may exercise one or more of the
following remedies, all of which shall be construed and held to be cumulative
and non-exclusive: (a) Terminate this Lease and re-enter and take possession of
the Leased Premises, in which event, Landlord is authorized to make such
repairs, redecorating, refurbishments or improvements to the Leased Premises as
may be necessary in the reasonable opinion of Landlord acting in good faith for
the purposes of reletting the Leased Premises and the costs and expenses
incurred in respect of such repairs, redecorating and refurbishments and the
expenses of such reletting (including brokerage commissions) shall be paid by
Tenant to Landlord within five (5) days after receipt of Landlord's statement;
or (b) Without terminating this Lease, re-enter and take possession of the
Leased Premises; or (c) Without such re-entry, recover possession of the Leased
Premises in the manner prescribed by any statute relating to summary process; or
(d) Without terminating this Lease, Landlord may relet the Leased Premises as
Landlord may see fit without thereby avoiding or terminating this Lease, and for
the purposes of such reletting, Landlord is authorized to make such repairs,
redecorating, refurbishments or improvements to the Leased Premises as may be
necessary in the reasonable opinion of Landlord acting in good faith for the
purpose of such reletting, and if a sufficient sum is not realized from such
reletting (after payment of all costs and expenses of such repairs, redecorating
and refurbishments and expenses of such reletting (including brokerage
commissions) and the collection of rent accruing therefrom) each month to equal
the Annual Basic Rent and Additional Rent payable hereunder, then Tenant shall
pay such deficiency each month within five (5) days after receipt of Landlord's
statement; or (e) Landlord may declare immediately due and payable all the
present value of the remaining installments of Annual Basic Rent and Additional
Rent (utilizing the discount rate of the Federal Reserve Bank situated nearest
to the location of the Building at the time of Landlord's declaration plus one
(1) percentage point), and such amount, less the present value of the fair
rental value of the Leased Premises for the remainder of the Lease Term
(utilizing the discount rate of the Federal Reserve Bank situated nearest to the
location of the Building at the time of Landlord's declaration plus one (1)
percentage point) shall be paid by Tenant within five (5) days after receipt of
Landlord's statement. Landlord shall not by re-entry or any other act, be deemed
to have terminated this Lease, or the liability of Tenant for the total Annual
Basic Rent and Additional Rent reserved hereunder or for any installment thereof
then due or thereafter accruing, or for damages, unless Landlord notifies Tenant
in writing that Landlord has so elected to terminate this Lease. After the
occurrence of an Event of Default, the acceptance of Annual Basic Rent or
Additional Rent, or the failure to re-enter by Landlord shall not be deemed to
be a waiver of Landlord's right to thereafter terminate this Lease and exercise
any other rights and remedies available to it, and Landlord may re-enter and
take possession of the Leased Premises as if no Annual Basic Rent or Additional
Rent had been accepted after the occurrence of an Event of Default. Upon an
Event of Default, Tenant shall also pay to Landlord all costs and expenses
incurred by Landlord, including court costs and attorneys' fees, in retaking or
otherwise obtaining possession of the Leased Premises, removing and storing all
equipment, fixtures and personal property on the Leased Premises and otherwise
enforcing any of Landlord's rights, remedies or recourses arising as a result of
an Event of Default.

         13.3 Additional Remedies. All of the remedies given to Landlord in this
Lease in the event Tenant commits an Event of Default are in addition to all
other rights or remedies available to a landlord at law, in equity or by
statute, including, without limitation, the right to seize and sell all goods,
equipment and personal property of Tenant located in the Leased Premises and
apply the proceeds thereof to all due and unpaid Annual Basic Rent, Additional
Rent and other amounts owing under the Lease. All rights, options and remedies
available to Landlord shall be construed and held to be cumulative, and no one
of them shall be exclusive of the other. Upon the occurrence of an Event of
Default, all rights, privileges and contingencies which may be exercised by
Tenant under the Lease, including, without limitation, options to renew, extend
and expand, as well as relocation rights, contraction rights and any other
rights which may be exercised by Tenant during the Lease Term, shall be void and
of no further force and effect.

                                       16
<PAGE>   19

         13.4 Interest on Past Due Amounts. In addition to the late charge
described in Article 14 below, if any installment of Annual Basic Rent or
Additional Rent is not paid within five (5) business days after the date when
due, it shall bear interest at the Default Rate; provided, however, this
provision shall not relieve Tenant from any default in the making of any payment
at the time and in the manner required by this Lease; and provided, further, in
no event shall the Default Rate exceed the maximum rate (if any) permitted by
applicable law.

         13.5 Landlord Default. In the event Landlord should neglect or fail to
perform or observe any of the covenants, provisions or conditions contained in
this Lease on its part to be performed or observed, and such failure continues
for thirty (30) days after written notice of default (or if more than thirty
(30) days shall be required because of the nature of the default, if Landlord
shall fail to commence the curing of such default within such thirty (30) day
period and proceed diligently thereafter), then Landlord shall be responsible to
Tenant for any actual damages sustained by Tenant as a result of Landlord's
breach, but not special or consequential damages; provided, however, that in the
event of an interruption of HVAC or electricity services, Landlord shall
promptly take commercially reasonable efforts to cure such interruption and
shall diligently pursue such cure until reinstatement of service. Should Tenant
give written notice to Landlord to correct any default, Tenant shall give
similar concurrent notice to the holder of any mortgages or deeds of trust
against the Building or the lessor of any ground lease (provided that the names
and addresses of such holders have been provided to Tenant), and prior to any
cancellation of this Lease, the holder of such mortgage or deed of trust and/or
the lessor under such ground lease shall be given a reasonable period of time to
correct or remedy such default. If and when such holder of such mortgage or deed
of trust and/or the lessor under any such ground lease has made performance on
behalf of Landlord, the default of Landlord shall be deemed cured.

                                14. LATE PAYMENTS

         Tenant hereby acknowledges that the late payment by Tenant to Landlord
of any monthly installment of Annual Basic Rent, any Additional Rent or any
other sums due hereunder will cause Landlord to incur costs not contemplated by
this Lease, the exact amount of which will be extremely difficult and
impracticable to ascertain. Such costs include but are not limited to
processing, administrative and accounting costs. Accordingly, if any monthly
installment of Annual Basic Rent, any Additional Rent or any other sum due from
Tenant shall not be received by Landlord within five (5) business days after the
date when due, Tenant shall pay to Landlord a late charge equal to five percent
(5%) of such overdue amount or Two Hundred and No/100 Dollars ($200.00),
whichever is greater. With respect to any late payment by Tenant that is subject
to a late charge, the acceptance of payment in full of all amounts past due and
the applicable late charge by Landlord shall constitute a waiver of Tenant's
default with respect to such overdue amount, and shall prevent Landlord from
exercising any of the other rights and remedies available to Landlord with
respect to that particular default by Tenant. Nothing contained in this Article
14 shall be deemed to authorize or grant to Tenant an option for the late
payment of Annual Basic Rent, Additional Rent or any other sum due hereunder.

                          15. ABANDONMENT AND SURRENDER

         15.1 Abandonment. Tenant shall not abandon the Leased Premises at any
time during the Lease Term. No act or thing done by Landlord or by any agent or
employee of Landlord during the Lease Term shall be deemed an acceptance of a
surrender of the Leased Premises unless such acceptance is expressed in writing
and duly executed by Landlord. Unless Landlord so agrees in writing, the
delivery of the key to the Leased Premises to any employee or agent of Landlord
shall not operate as a termination of this Lease or as a surrender of the Leased
Premises,

         15.2 Surrender. Tenant shall, upon the expiration or earlier
termination of this Lease, peaceably surrender the Leased Premises, including
Tenant Improvements and Tenant's improvements and/or alterations installed
pursuant to Article 7.2, in a janitorial clean condition and otherwise in as
good condition as when Tenant, took possession, except for (i) reasonable wear
and tear subsequent to the last repair replacement, restoration, alteration or
renewal; (ii) loss by fire or other casualty, and (iii) loss by condemnation. If
Tenant shall abandon or surrender the Leased Premises, or be dispossessed by
process of law or otherwise, any personal property and fixtures belonging to
Tenant and left in the Leased Premises shall be deemed abandoned and, at
Landlord's option, title shall pass to Landlord under this Lease as by a bill of
sale. Landlord may, however, if it so elects, remove all or any part of such
personal property from the Leased Premises and the costs incurred by Landlord in
connection with such removal, including storage costs and the cost of

                                       17
<PAGE>   20

repairing any damage to the Leased Premises, the Building and/or the Property
caused by such removal shall be paid by Tenant within five (5) days after
receipt of Landlord's statement. Upon the expiration or earlier termination of
this Lease, Tenant shall surrender to Landlord all keys to the Leased Premises
and shall inform Landlord of the combination of any vaults, locks and safes left
on the Leased Premises. The obligations of Tenant under this Article 15.2 shall
survive the expiration or earlier termination of this Lease. Tenant shall
indemnify Landlord against any loss or liability resulting from delay by Tenant
in so surrendering the Premises, including, without limitation, any claims made
by any succeeding Tenant founded on such delay Tenant shall give written notice
to Landlord at least thirty (30) days prior to vacating the Leased Premises for
the express purpose of arranging a meeting with Landlord for a joint inspection
of the Leased Premises. In the event of Tenant's failure to give such notice or
to participate in such joint inspection, Landlord's inspection at or after
Tenant's vacation of the Leased Premises shall be conclusively deemed correct
for purposes of determining Tenant's liability for repairs and restoration
hereunder.

                       16. INDEMNIFICATION AND EXCULPATION

         16.1 Indemnification. Tenant shall indemnify, defend and hold Landlord
harmless from and against, and shall be responsible for, all claims, damages,
losses, costs, liens, encumbrances, liabilities and expenses, including
reasonable attorneys', accountants' and investigators' fees and court costs
(collectively, the "Claims"), however caused, arising in whole or in part from
Tenant's use of all or any part of the Leased Premises or the Generator or the
conduct of Tenant's business or from any activity, work or thing done or
permitted by Tenant or by any invitee, servant, agent, employee or subtenant of
Tenant in the Leased Premises or with respect to the Generator, and shall
further indemnify, defend and hold Landlord harmless from and against, and shall
be responsible for, all Claims arising in whole or in part from any breach or
default in the performance of any obligation on Tenant's part to be performed
under the terms of this Lease or arising in whole or in part from any negligence
or willful misconduct of Tenant or by any invitee, servant, agent, employee or
subtenant of Tenant anywhere in the Leased Premises, the Building and/or the
Property or with respect to the Generator. The preceding sentence shall not
apply to any Claim arising from any negligence or wilful misconduct by Landlord
or any of its invitees, servants, agents or employees. In case any action or
proceeding is brought against Landlord to which this indemnification shall be
applicable, Tenant shall pay all Claims resulting therefrom and shall defend
such action or proceeding, if Landlord shall so request, at Tenant's sole cost
and expense, by counsel reasonably satisfactory to Landlord. The obligations of
Tenant under this Article 16.1 shall survive the expiration or earlier
termination of this Lease.

         16.2 Exculpation. Neither Landlord nor its agents or employees shall be
liable for (i) any injury or damage to persons or property resulting from fire,
explosion, falling plaster, steam, gas, electricity, sewage, odor, noise, water
or rain which may leak from any part of the Building or from the pipes,
appliances or plumbing works therein, or from the roof of any structure on the
Property, or from any streets or subsurfaces on or adjacent to the Building or
the Property, or from any other place or resulting from dampness, (ii) any
defects in the Leased Premises, (iii) negligence or misconduct, including, but
not limited to, criminal acts, by maintenance or other personnel or contractors
serving the Leased Premises, the Building and/or the Property, other tenants or
third parties unless arising from the negligence or wilful misconduct of
Landlord, its agents or employees. All property of Tenant kept or stored on the
Property shall be so kept or stored at the risk of Tenant only, and Tenant shall
indemnify, defend and hold Landlord harmless from and against, and shall be
responsible for, any Claims arising out of damage to the same, including
subrogation claims by Tenant's insurance carriers, unless such damage shall be
caused by the willful act or negligence of Landlord and through no fault of
Tenant. Tenant shall give prompt notice to Landlord with respect to any defects,
fires or accidents which Tenant observes in the Leased Premises, the Building
and/or the Property.

                              17. ENTRY BY LANDLORD

         Landlord reserves and shall at any and all reasonable times during
business hours and upon prior notice (except in cases of emergency) have the
right to enter the Leased Premises, to inspect the same to submit the Leased
Premises to prospective purchasers or tenants, to post notices of
non-responsibility, and to alter, improve or repair the Leased Premises and any

waiver of any of the restrictions or prohibitions of this Article 19 and such
restrictions or prohibitions shall apply to each successive transfer, assignment
or subletting hereunder, if any.

the Leased Premises; (c) the terms and the provisions of the proposed sublease
or assignment; and (d) such financial information as Landlord may reasonably

party intends to conduct in the Leased Premises, and (e) a fully executed
original of such assignment providing for an express assumption by the assignee
of all of the terms, covenants and conditions of this Lease is promptly
delivered to Landlord.

this 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 by an amount equal to one-half (1/2) of the
difference, if any, between the Annual Basic Rent payable pursuant to this
Lease, as adjusted, and 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
or subletting be less than the Annual Basic Rent specified in Article 1.12
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

subletting, occupancy, transfer or collection shall be deemed a waiver of

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 shall not be released from
performance of any of the terms, covenants and conditions of this Lease.

and (d) the transferee agrees to use and occupy the Leased Premises solely for

Lease.

         19.9 Withholding Consent. Without limiting the grounds for withholding
consent which may be reasonable, it shall be reasonable for Landlord to withhold
consent if the proposed assignee or subtenant is a tenant in default of such
tenant's lease (or the termination by such assignee or

by which date Tenant shall vacate and surrender the Leased Premises to Landlord.
The Annual Basic Rent and Additional Rent shall be pro rated to the earlier of
the termination of this Lease or such date as Tenant is required to vacate the
Leased Premises by reason of the taking. If this Lease is not terminated as a
result of a partial taking of the Leased Premises, the Annual Basic Rent and
Additional Rent shall be equitably adjusted according to the rentable area of
the Leased Premises and Building remaining.

         29.2 Award. In the event of a taking of all or any part of the Building
or the Property, all of the proceeds or the award, judgment, settlement or
damages payable by the condemning authority shall be and remain the sole and
exclusive property of Landlord, and Tenant hereby assigns all of its right,
title and interest in and to any such award, judgment, settlement or damages to
Landlord. Tenant shall, however, have the right, to the extent that the same
shall not reduce or prejudice amounts available to Landlord, to claim from the
condemning authority, but not from Landlord, such compensation as may be
recoverable by Tenant in its own right for relocation benefits, moving expenses,
and damage to Tenant's personal property and trade fixtures.

                                   30. NOTICES

be in writing and shall be delivered in person, sent by any public or private
express delivery service or deposited with the United States Postal Service or a
successor agency, certified or registered mail, return receipt requested,
postage pre-paid, addressed as set forth in the Basic Provisions, or at such
other address as a party may from time to time designate by notice hereunder.
Notice shall be effective upon delivery. The inability to deliver a notice
because of a changed address of which no notice was given or a rejection or
other refusal to accept any notice shall be deemed to be the receipt of the
notice as of the date of such inability to deliver or rejection or refusal to
accept. Any notice to be given by Landlord may be given by the legal counsel
and/or the authorized agent of Landlord.

                            31. RULES AND REGULATIONS

         Tenant shall abide by all rules and regulations (the "Rules and
Regulations") of the Building and the Property imposed by Landlord, as attached
hereto as Exhibit "T" or as may hereafter be issued by Landlord. Such Rules and
Regulations are imposed to enhance the cleanliness, appearance, maintenance,
order and use of the Leased Premises, the Building and the Property, and the
proper enjoyment of the Building and the Property by all tenants and their
clients, customers and employees. The Rules and Regulations may be changed from
time to time upon ten (10) days notice to Tenant. Breach of the Rules and
Regulations, by Tenant shall constitute an Event of Default if such breach is
not fully cured within ten (10) days after written notice to Tenant by Landlord.
Landlord shall not be responsible to Tenant for nonperformance by any other
tenant, occupant or invitee of the Building or the Property of any Rules or
Regulations.

                           32. ACCORD AND SATISFACTION

         No payment by Tenant or receipt by Landlord of a lesser amount than the
monthly installment of Annual Base Rent and Additional Rent (jointly called
"Rent" in this Article 32), shall be deemed to be other than on account of the
earliest stipulated Rent due and not yet paid, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as Rent
be deemed an accord and satisfaction. Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such Rent or to
pursue any other remedy in this Lease. No receipt of money by Landlord from
Tenant after the termination of this Lease, after

                                       25
<PAGE>   28

the service of any notice relating to the termination of this Lease, after the
commencement of any suit, or after final judgment for possession of the Leased
Premises, shall reinstate, continue or extend the Lease Term or affect any such
notice, demand, suit or judgment.

                            33. BANKRUPTCY OF TENANT

         33.1 Charter 7. If a petition is filed by, or an order for relief is
entered against Tenant under Chapter 7 of the Bankruptcy Code and the trustee of
Tenant elects to assume this Lease for the purpose of assigning it, the election
or assignment, or both, may be made only if all of the terms and conditions of
Articles 33.2 and 33.4 below are satisfied. If the trustee fails to elect to
assume this Lease for the purpose of assigning it within sixty (60) days after
appointment, this Lease will be deemed to have been rejected. To be effective,
an election to assume this Lease must be in writing and addressed to Landlord
and, in Landlord's business judgment, all of the conditions hereinafter stated,
which Landlord and Tenant acknowledge to be commercially reasonable, must have
been satisfied. Landlord shall then immediately be entitled to possession of the
Premises without further obligation to Tenant or the trustee, and this Lease
will be terminated. Landlord's right to be compensated for damages in the
bankruptcy proceeding, however, shall survive.

         33.2 Chapters 11 and 13. If Tenant files a petition for reorganization
under Chapters 11 or 13 of the Bankruptcy Code or a proceeding that is filed by
or against Tenant under any other chapter of the Bankruptcy Code is converted to
a Chapter 11 or 13 proceeding and Tenant's trustee or Tenant as a
debtor-in-possession fails to assume this Lease within sixty (60) days from the
date of the filing of the petition or the conversion, the trustee or the
debtor-in-possession will be deemed to have rejected this Lease. To be
effective, an election to assume this Lease must be in writing and addressed to
Landlord and, in Landlord's business judgment, all of the following conditions,
which Landlord and Tenant acknowledge to be commercially reasonable, must have
been satisfied:

                  (a) The trustee or the debtor-in-possession has cured or has
provided to Landlord adequate assurance, as defined in this Article 33.2 that;

                           (1) The trustee will cure all monetary defaults under
this Lease within ten (10) days from the date of the assumption; and

                           (2) The trustee will cure all non-monetary defaults
under this Lease within thirty (30) days from the date of the assumption.

                  (b) The trustee or the debtor-in-possession has compensated
Landlord, or has provided to Landlord adequate assurance, as defined in this
Article 33.2, that within ten (10) days from the date of the assumption Landlord
will be compensated for any pecuniary loss it incurred arising from the default
of Tenant, the trustee, or the debtor-in-possession as recited in Landlord's
written statement of pecuniary loss sent to the trustee or the
debtor-in-possession. For purposes of this Lease, pecuniary loss shall include
all attorneys' fees and court costs incurred by Landlord in connection with any
bankruptcy proceeding filed by or against Tenant.

                  (c) The trustee or the debtor-in-possession has provided
Landlord with adequate assurance of the future performance of each of Tenant's
obligations under the Lease; provided, however, that:

                           (1) The trustee or debtor-in-possession will also
deposit with Landlord as security for the timely payment of Annual Basic Rent
and Additional Rent, an amount equal to three months Annual Basic Rent and
Additional Rent accruing under this Lease.

                           (2) If not otherwise required by the terms of this
Lease, the trustee or the debtor-in-possession will also pay in advance, on each
day that the Annual Basic Rent is payable, one-twelfth of Tenant's estimated
annual obligations under the Lease for the Additional Rent.

                           (3) From and after the date of the assumption of this
Lease, the trustee or the debtor-in-possession will pay the Annual Basic Rent
and Additional Rent as provided in Article 5 above.

                           (4) The obligations imposed upon the trustee or the
debtor-in-possession will continue for Tenant after the completion of bankruptcy
proceedings.

                  (d) Landlord has determined that the assumption of the Lease
will not:

                                       26
<PAGE>   29

                           (1) Breach any provisions in any other lease,
mortgage, financing agreement, or other agreement by which Landlord is bound
relating to the Property; or

                           (2) Disrupt, in Landlord's judgment, the tenant mix
of the Building or any other attempt by Landlord to provide a specific variety
of Tenants in the Building that, in Landlord's judgment, would be most
beneficial to all of the tenants of the Building and would enhance the image,
reputation, and profitability of the Building.

                  (e) For purposes of this Article 33.2 "adequate assurance"
means that:

                           (1) Landlord will determine that the trustee or the
debtor-in-possession has, and will continue to have, sufficient unencumbered
assets after the payment of all secured obligations and administrative expenses
to assure Landlord that the trustee or the debtor-in-possession will have
sufficient funds to fulfill Tenant's obligations under this Lease and to keep
the Leased Premises properly staffed with sufficient employees to conduct a
fully operational, actively promoted business on the Leased Premises; and

                           (2) An order will have been entered segregating
sufficient cash payable to Landlord and/or a valid and perfected first lien and
security interest will have been granted in property of Tenant, trustee, or
debtor-in-possession that is acceptable for value and kind to Landlord, to
secure to Landlord the obligation of the trustee or debtor-in-possession to cure
the monetary or non-monetary defaults under this Lease within the time periods
set forth above.

          33.3 Landlord's Right to Terminate. In the event that this Lease is
assumed by a trustee appointed for Tenant or by Tenant as debtor-in-possession
under the provisions of Article 33.2 above and, thereafter, Tenant is either
adjudicated a bankrupt or files a subsequent petition for arrangement under
chapter 11 of the Bankruptcy Code, then Landlord may terminate, at its option,
this Lease and all Tenant's rights under it, by giving written notice of
Landlord's election to terminate,

          33.4 Assignment by Trustee. If the trustee or the debtor-in-possession
has assumed the Lease, under the terms of Article 33.1 or 33.2 above, and elects
to assign Tenant's interest under this Lease or the estate created by that
interest to any other person, that interest or estate may be assigned only if
Landlord acknowledges in writing that the intended assignee has provided
adequate assurance, as defined in this Article 33.4 of future performance of all
of the terms, covenants, and conditions of this Lease to be performed by Tenant.

          33.5 Adequate Assurance. For the purposes of this Article 33 "adequate
assurance of future performance" means that Landlord has ascertained that each
of the following conditions has been satisfied:

                  (1) The assignee has submitted a current financial statement,
audited by a certified public accountant, that shows a net worth and working
capital in amounts determined by Landlord to be sufficient to assure the future
performance by the assignee of Tenant's obligations under this Lease;

                  (2) If requested by Landlord, the assignee will obtain
guarantees, in form and substance satisfactory to Landlord from one or more
persons who satisfy Landlord's standards of creditworthiness;

                  (3) Landlord has obtained all consents or waivers from any
third party required under any lease, mortgage, financing arrangement or other
agreement by which Landlord is bound, to enable Landlord to permit the
assignment;

                  (4) When, pursuant to the Bankruptcy Code, the trustee or the
debtor-in-possession is obligated to pay reasonable use and occupancy charges
for the use of all or part of the Leased Premises, the charges will not be less
than the Annual Basic Rent and Additional Rent.

          33.6 Consent of Landlord. Neither Tenant's interest in the Lease nor
any estate of Tenant created in the Lease will pass to any trustee, receiver,
assignee for the benefit of creditors, or any other person or entity, or
otherwise by operation of law under the laws of any state having jurisdiction of
the person or property of Tenant unless Landlord consents in writing to the
transfer. Landlord's acceptance of Annual Basic Rent or Additional Rent or any
other payments from any trustee, receiver, assignee, person, or other entity
will not be deemed to have waived, or waive, the

                                       27
<PAGE>   30

need to obtain Landlord's consent or Landlord's right to terminate this Lease
for any transfer of Tenant's interest under this Lease without that consent.

unforeseeable consequential damages and the cost of any Remedial Work. Neither

obligations pursuant to this Article 34. The foregoing indemnity shall be in
addition to and not a limitation of the indemnification provisions of Article 16
of this Lease. Tenant's obligations pursuant to this Article 34 shall survive
the termination or expiration of this Lease.

warrants to Landlord as follows:

obligation of Tenant, enforceable against Tenant in accordance with its terms,

considered in a proceeding in equity or at law, and to the qualification that

more instances upon the strict performance of any one or more of the obligations
of this Lease, or to exercise any election herein contained, shall not be

such one or more obligations of this Lease or the right to exercise such
election, but the same shall continue and remain in full force and effect with
respect to any subsequent breach, act or omission.

         35.9 Severability. If any clause or provision of this Lease is or
becomes illegal or unenforceable because of any present or future law or
regulation of any governmental body or entity

<PAGE>   33
effective during the Lease Term, the intention of the parties is that the
remaining provisions of this Lease shall not be affected thereby.

         35.10 Exhibits. If any provision contained in an Exhibit, Rider or

or any Exhibits, Riders or amendments hereto.

         35.12 No Merger. The voluntary or other surrender of this Lease by
Tenant or a mutual cancellation of this Lease shall not work as a merger and

subtenancies, or operate as an assignment to Landlord of any or all of such
subleases or subtenancies.

         35.13 Force Majeure. Any prevention, delay or stoppage due to strikes,
lockouts, labor disputes, acts of God, inability to obtain labor or materials
for reasonable substitutes therefor, governmental restrictions, regulations or

all persons causing or authorized to cause such excavation or construction
license to enter onto the Leased Premises for the purpose of doing such work as

this Lease, insofar as the covenants or agreements on the part of the Landlord
are concerned, shall be limited to mean and include only the owner or owners of

transfers of such interest, the Landlord herein named (and in the case of any
subsequent transfer, the then transferor) shall thereafter be relieved of all
liability for the performance of any covenants or agreements on the part of the
Landlord contained in this Lease.

         35.17 Limitation on Landlord's Liability. If Landlord becomes obligated
to pay Tenant any judgment arising out of any failure by the Landlord to perform
or observe any of the terms, covenants conditions or provisions to be performed
or observed by Landlord under this Lease, Tenant shall be limited in the
satisfaction of such judgment solely to Landlord's interest in the Building and
the Property or any proceeds arising from the sale thereof and no other property
or assets of Landlord or the individual partners, directors, officers or
shareholders of Landlord or its constituent partners shall be subject to levy,
execution or other enforcement procedure whatsoever for the satisfaction of any
such money judgment. In the event Tenant obtains a money judgment against
Landlord and Landlord does not pay or bond over such money judgment within
thirty (30) days after entry thereof, Tenant may offset the amount of such
judgment, with interest at the Default Rate, against the Annual Basic Rent and
Additional Rent payable under this Lease until, by virtue of such offset, Tenant
shall have recovered the full amount of its judgment. Exercise by Tenant of the
foregoing right of offset shall not be deemed an election of remedies and Tenant
shall have the right, either concurrently or consecutively, to pursue all other
remedies available to Tenant at law or in equity, subject to the limitation on
remedies set forth in this Lease.

*Subject to the terms of Article 5.1.

                  (b) Renewal Term: (i) Landlord and Tenant shall have sixty
(60) days after Landlord receives the Option Notice within which to agree on the
Annual Basic Rental and Parking Charge for the Renewal Term based upon
ninety-five percent (95%) of the "THEN FAIR MARKET RENTAL VALUE OF THE PREMISES"
as defined below. If the parties agree on the Annual Basic Rental and Parking
Charge for the Renewal Term within sixty (60) days, they shall amend this Lease
by stating the Annual Basic Rental and Parking Charge for the Renewal Term.

                                   Rider 1 - 1
<PAGE>   36

                           (ii) If they are unable to agree on the Annual Basic
Rental and Parking Charge for the Renewal Term within the sixty (60) day period,
then the Annual Basic Rental and Parking Charge shall be ninety-five percent
(95%) of the "THEN FAIR MARKET RENTAL VALUE OF THE PREMISES" as determined in
accordance with this Rider.

                           (iii) The "THEN FAIR MARKET RENTAL VALUE OF THE
PREMISES" means what a landlord under no compulsion to lease the Premises and a
tenant under no compulsion to lease the Premises, would determine as rent for
the Renewal Term, as of the commencement of the Renewal Term, taking into
consideration the use permitted under the Lease and the quality, size, shape,
design and location of the Premises within the Building. The then fair market
rental value of the Premises for the first year of the Renewal Term will not be
less than the Annual Basic Rental and Parking Charge payable during the last
year of the Initial Term.

                           (iv) Within seven (7) days after the expiration of
the sixty (60) day period set forth in Subsection 1.12 above, Landlord and
Tenant shall each appoint an independent real estate broker with at least five
(5) full years full-time commercial brokerage experience in the area in which
the Premises are located to determine the then fair market rental value of the
Premises. If either the Landlord or the Tenant does not appoint a broker within
ten (10) days after the other has given notice of the name of its broker, the
single broker appointed shall be the sole broker and shall set the then fair
market rental value of the Premises. If two (2) brokers are appointed pursuant
to this paragraph, they shall meet promptly and attempt to set the then fair
market rental value of the Premises. If they are unable to agree within the
thirty (30) days after the second broker has been appointed, they shall attempt
to elect a third broker meeting the qualifications stated in this paragraph
within ten (10) days after the last day the two (2) brokers are given to set the
then fair market rental value of the Premises. If they are unable to agree on
the third broker either the Landlord or Tenant may petition the presiding civil
court judge of the Maricopa County Superior Court for the selection of a third
broker who meets the qualifications stated in this paragraph. Tenant and
Landlord shall each bear one-half (1/2) of the cost of appointing the brokers
and of paying the broker's fees.

                           Within thirty (30) days after the selection of the
third broker, a majority of the brokers shall set the then fair market rental
value of the Premises. If a majority of the brokers are unable to set the then
fair market rental value of the Premises within thirty (30) days after selection
of the third broker, the three (3) opinions shall be averaged and the average
shall be the then fair market rental value of the Premises.

                           The broker(s) determination of the fair market rental
value of the Leased Premises shall contemplate an Annual Basic Rent that
increases over the Renewal Term.

                           Within five (5) days after the final determination by
the broker(s) of the fair market rental value of the Premises, both Landlord and
Tenant shall have the right to reject or withdraw the exercise of the Option, as
applicable, by delivering notice to the other party. Notwithstanding the
provisions of Paragraph 2(b)(iv) to the contrary, the rejecting or withdrawing
party, as applicable, shall bear the entire cost of appointing the broker(s) and
paying the brokers' fee.

         3. Definitions. Capitalized terms used in this Rider without definition
shall have the definition assigned to such terms in the Lease to which this
Rider is attached, unless the context requires otherwise.

         4. Full Force and Effect. Except as specifically modified by this
Rider, the tease to which this Rider is attached remains in full force and
effect.

Tenant does not timely exercise the Option, or if Landlord and Tenant do not
execute a supplemental agreement to this Lease within thirty (30) days after

the Lease) shall be in occupancy of the Lease Premises, and in the event First
Data Corporation does not renew its lease for that portion of the space in Suite

offering the Additional Space for lease, Landlord shall deliver to Tenant
written notice (the "Proposal Notice") which Proposal Notice shall set forth the
Annual Basic Rent, Additional Rent and tenant improvements at which Landlord
intends to market the Additional Space. Tenant shall have an option (the
"Option") exercisable by written notice to Landlord within ten (10) days after
receipt of the Proposal Notice to lease all of the Additional Space upon the
terms and conditions contained in the Proposal Notice. Promptly after Tenant
exercises the Option, Landlord and Tenant shall exercise supplement agreement to
this Lease, in a form satisfactory to Landlord and Tenant, incorporating the

         1. Landlord shall provide the Leased Premises to Tenant, and Tenant
accepts a portion of Suite 200, which comprises a portion of the Leased
Premises, in its present "as is" condition. Tenant represents and warrants that
it has inspected this portion of the Leased Premises prior to execution of this
Lease, and that it is relying on its own inspection in executing this Lease and
not on any statement, representation or warranty of Landlord, its agents or
employees.

         2. COMPLETION SCHEDULE. Attached to this Work Letter is a schedule (the
"Work Schedule") setting forth the time table for the planning and completion of
the installation of the tenant improvements to be constructed in the Leased
Premises (the "Tenant Improvements"). The Work Schedule sets forth each of the
various items of work to be done in connection with the completion of the Tenant
Improvements and shall become the basis for completing the Tenant Improvements.
Landlord and Tenant acknowledge and agree that time is of the essence with
respect to their respective obligations as set forth in this Work Letter.

described on Annex I to this Exhibit "H", which work shall be done in the Leased
Premises pursuant to the Tenant Improvements Plans described in Paragraph 4
below.

         4. TENANT IMPROVEMENT PLANS. Tenant shall meet with Landlord's
architect and/or space planner for the purposes of preparing a space plan for

specifications for the Tenant Improvements. Such final working drawings and
specifications are referred to in this Work Letter as the "Tenant Improvement
Plans."

         5. PREPARATION OF TENANT IMPROVEMENT PLANS AND FINAL PRICING. After the
preparation of the space plan and after Tenant's approval thereof in accordance

to Tenant the Tenant Improvement Plans. Promptly after the approval of the

Schedule, the Tenant Improvement Plans shall be submitted to the appropriate
governmental body for plan checking and building permits. Landlord, with
Tenant's cooperation, shall cause to be made such changes in the Tenant
Improvement Plans necessary to obtain required permits. Tenant acknowledges that
after final approval of the Tenant Improvement Plans, no further changes to the
Tenant Improvement Plans may be made without the prior written consent of
Landlord, which consent shall not be unreasonably withheld but may be
conditioned on the agreement by Tenant to pay all additional costs and expenses
resulting from such requested changes that exceed the Allowance (defined below).

         6. CONSTRUCTION OF TENANT IMPROVEMENTS. After the Tenant Improvement
Plans have been prepared and approved, and building permits for the Tenant
Improvements have been issued, Landlord shall enter into a construction contract
with a licensed and bonded contractor for the installation of the Tenant
Improvements in accordance with the Tenant Improvement Plans. The Tenant
Improvements shall be constructed in a good, workmanlike and lien free manner,
and in conformance with applicable building codes. Landlord shall supervise the
completion of the Tenant Improvements and shall endeavor in good faith to secure
the completion of the Tenant Improvements in accordance with the Work Schedule.
The cost of the Tenant Improvements shall be paid as provided in Paragraph 7
below. Tenant shall accept the Tenant Improvements upon substantial completion
thereof, as reasonably determined by Landlord's architect, which determination
shall be set forth in a certificate of Landlord's architect certified to
Landlord and Tenant.

         7. PAYMENT OF THE COST OF THE TENANT IMPROVEMENTS.

in Paragraph 7(a) above shall be charged against the Allowance. In the event the
anticipated cost of installing the Tenant Improvements, as established by
Landlord's final pricing schedule, shall exceed the Allowance, or in the event
any of the Tenant Improvements are not to be paid for from the Allowance, the
excess shall be paid by Tenant to Landlord prior to the commencement of
construction of the Tenant Improvements.

                  c. CHANGES TO TENANT IMPROVEMENT PLANS. In the event that
Tenant shall request any changes or substitutions to the Tenant Improvement
Plans, after the Tenant Improvement Plans have been prepared and the final
pricing established by Landlord, any additional costs attributable thereto shall
be paid by Tenant to Landlord prior to the commencement of the work represented
by such changes, unless covered under the Allowance.

                  d. UNUSED ALLOWANCE. Any unused part of the Allowance shall be
credited toward the fist payments due from Tenant for the Annual Basic Rent and
Additional Rent.

         8. EARLY ENTRY. Landlord shall permit Tenant and Tenant's agents to
enter the Leased Premises prior to the Commencement Date in order that Tenant
may do such work as may be required by Tenant to make the Leased Premises ready
for Tenant's use and occupancy. If Landlord permits such entry prior to the
Commencement Date, such permission is conditioned upon Tenant and its agents,
contractors, employees and invitees working in harmony and not interfering with
Landlord and its agents, contractors and employees in the installation of the
Tenant Improvements or in the performance of work for other tenants and
occupants of the Building. If at any time such entry shall cause or threaten to
cause disharmony or interference, Landlord shall have the right to withdraw such
permission upon twenty-four (24) hours notice to Tenant. Any entry into the
Leased Premises by Tenant prior to the Commencement Date shall be subject to all
of the terms, covenants,

conditions and provisions of the Lease, other than with respect to Tenant's
obligation to pay Annual Basic Rent. Tenant acknowledges and agrees that
Landlord shall not be liable in any way for any injury, loss or damage which may
occur to Tenant, its agents, contractors and employees or to Tenant's work and
installations made in the Leased Premises or to property placed therein prior to
the Commencement Date, all of the same being at Tenant's sole risk, provided,
however, that Landlord shall be liable to Tenant for the gross negligence of
Landlord, its agents, contractors and employees.

         9. PUNCH LIST PROCEDURE. Within fifteen (15) days after the Landlord's
notice of substantial completion, Tenant shall prepare A list (the "Punch List")
of any deficiencies or incompleted work regarding any Tenant Improvements.
Provided that such items are Landlord's responsibility pursuant to the Tenant
Improvement Plans, Landlord shall correct such deficiencies or incompleted work
within a reasonable period of time, but in no event later than sixty (60) days
after receipt of the Punch List, after which Landlord shall have no further
obligation to alter change, decorate or improve the Leased Premises, whether to
adapt the same for the use for which it is leased or for any other purpose. The
existence of such deficiencies or incompleted work shall not effect Tenant's
obligation to accept the Leased Premises as otherwise required hereunder.

         10. ASSIGNMENT OF WARRANTIES. Landlord shall assign to Tenant the
non-exclusive right to enforce any and all warranties which Landlord may receive
from any contractor, supplier or other person or entity involved with
construction of the Tenant Improvements, which assignment shall continue until
the expiration or sooner termination of the Lease or the expiration of the
warranty, whichever occurs first.

                            33. BANKRUPTCY OF TENANT

         33.1 Chapter 7. If a petition is filed by, or an order for relief is
entered against Tenant under Chapter 7 of the Bankruptcy Code and the trustee of
Tenant elects to assume this Lease for the purpose of assigning it, the election
or assignment, or both, may be made only if all of the terms and conditions of
Articles 33.2 and 33.4 below are satisfied. If the trustee fails to elect to
assume this Lease for the purpose of assigning it within sixty (60) days after
appointment, this Lease will be deemed to have been rejected. To be effective,
an election to assume this Lease must be in writing and addressed to Landlord
and, in Landlord's business judgment, all of the conditions hereinafter stated,
which Landlord and Tenant acknowledge to be commercially reasonable, must have
been satisfied. Landlord shall then immediately be entitled to possession of the
Premises without further obligation to Tenant or the trustee, and this Lease
will be terminated. Landlord's right to be compensated for damages in the
bankruptcy proceeding, however, shall survive.

         33.2 Chapters 11 and 13. If Tenant flies a petition for reorganization
under Chapters 11 or 13 of the Bankruptcy Code or a proceeding that is filed by
or against Tenant under any other chapter of the Bankruptcy Code is converted to
a Chapter 11 or 13 proceeding and Tenant's trustee or Tenant as a
debtor-in-possession fails to assume this Lease within sixty (60) days from the
date of the filing of the petition or the conversion, the trustee or the
debtor-in-possession will be deemed to have rejected this Lease. To be
effective, an election to assume this Lease must be in writing and addressed to
Landlord and, in Landlord's business judgment, all of the following conditions,
which Landlord and Tenant acknowledge to be commercially reasonable, must have
been satisfied:

                  (a) The trustee or the debtor-in-possession has cured or has
provided to Landlord adequate assurance, as defined in this Article 33.2, that;

                           (1) The trustee will cure all monetary defaults under
this Lease within ten (10) days from the date of the assumption; and

                           (2) The trustee will cure all non-monetary defaults
under this Lease within thirty (30) days from the date of the assumption.

                  (b) The trustee or the debtor-in-possession has compensated
Landlord, or has provided to Landlord adequate assurance, as defined in this
Article 33.2, that within ten (10) days from the date of the assumption Landlord
will be compensated for any pecuniary loss it incurred arising from the default
of Tenant, the trustee, or the debtor-in-possession as recited in Landlord's
written statement of pecuniary loss sent to the trustee or the
debtor-in-possession. For purposes of this Lease, pecuniary loss shall include
all attorneys' fees and court costs incurred by Landlord in connection with any
bankruptcy proceeding filed by or against Tenant.

                  (c) The trustee or the debtor-in-possession has provided
Landlord with adequate assurance of the future performance of each of Tenant's
obligations under the Lease; provided, however, that:

                           (1) The trustee or debtor-in-possession will also
deposit with Landlord as security for the timely payment of Annual Basic Rent
and Additional Rent, an amount equal to three mouths Annual Basic Rent and
Additional Rent accruing under this Lease.

                           (2) If not otherwise required by the terms of this
Lease, the trustee or the debtor-in-possession will also pay in advance, on each
day that the Annual Basic Rent is payable, one-twelfth of Tenant's estimated
annual obligations under the Lease for the Additional Rent.

                           (3) From and after the date of the assumption of
this Lease, the trustee or the debtor-in-possession will pay the Annual Basic
Rent and Additional Rent as provided in Article 5 above.

                           (4) The obligations imposed upon the trustee or the
debtor-in-possession will continue for Tenant after the completion of bankruptcy
proceedings.

                  (d) Landlord has determined that the assumption of the Lease
will not:

         C. The parties desire to amend the Lease subject to and in accordance
with the further terms, covenants and conditions of this Amendment.

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the Lease, the foregoing Recitals,

respect to the additional space known as Suite 212 (the "SUITE 212 EFFECTIVE

square feet by adding thereto Suite 212. Effective thirty (30) days after the
date Tenant receives written notice of the date Suite 200 is vacated by the

a portion of Suite 240 (which is within the Leased Premises) which portion shall

this Amendment, as of the later to occur of the Suite 212 Effective

<PAGE>   65

modified by replacing "56,045 rentable square feet" with "70,434 rentable square
feet". From and after the later of the Suite 212 Effective Date or the Suite 200
Effective Date, all references in the Lease to the "Leased Premises" shall be
deemed references to the Leased Premises as modified by this Amendment.

         3. Landlord and Tenant acknowledge that Suite 200 is currently occupied
pursuant to a Lease that expires on November 30, 1997. Landlord shall use
commercially reasonable efforts to ensure that Suite 200 is vacated as of
November 30, 1997.

         4. Landlord grants Tenant the right to occupy Suite 212 and Suite 200
commencing on the applicable Effective Date and terminating on the Expiration
Date (as defined in the Lease), as the same may be extended. Landlord shall
provide the Additional Leased Space to Tenant and Tenant accepts the Additional
Leased Space in its present "as is" condition.

         5. The Annual Basic Rent for Suite 212 shall be $140,043.75 ($11,670.31
per month) based on a rental rate of $19.25 per rentable square foot. The Annual

Date. Accordingly, from and after the later of the Suite 212 Effective Date or
the Suite 200 Effective Date Article 1.13 of the Lease is hereby deleted in its
entirety and replaced with the following:

The rental amounts are calculated based on the assumption that the Suite 240
Reduction shall occur on January 1, 1998. In the event that the Suite 240

basis.

         8. Except as set forth in this Amendment, Tenant's occupancy of the
Additional Leased Space and Landlord's obligations with respect to Tenant's
Occupancy of the Additional Leased Space shall otherwise be subject to all of
the terms and conditions of the Lease.

         9. Landlord shall provide to Tenant a Tenant Improvement Allowance with
respect to the Additional Leased Space of $165,350.00 (the "AMENDMENT
ALLOWANCE") based on a rate of Twenty-Five and No/100 Dollars ($25.00) per
usable square foot of Suite 212. Tenant's use of the Amendment Allowance is
subject to the terms and conditions of Exhibit "H" to the Lease. For a period
commencing on the date of this Amendment and expiring twelve (12) months
thereafter, Tenant shall have the right to use the Amendment Allowance for
Tenant Improvements in the Additional Leased space and/or any other portion of
the Leased Premises. Notwithstanding anything contained in Exhibit H to the
contrary, no portion of any unused Amendment Allowance may be credited toward
payments due from Tenant for the Annual Basic Rent and Additional Rent due and
payable under the Lease. Further notwithstanding any provision of Exhibit "H" to
the contrary, Tenant shall have the right to select, contract with and supervise
the contractor that shall perform the Tenant Improvements, subject to Landlord's
approval, which approval shall not be unreasonably withheld.

replaced with EXHIBIT "C" attached hereto.

         11. Tenant hereby affirms by execution of this Amendment that the Lease
is in full force and effect and Tenant does not have any presently existing
claims against Landlord or any offsets against rent due under the Lease. There
are no defaults of Landlord under the Lease and there are no existing
circumstances which with the passage, notice, or both, would give rise to a
default under the Lease. Landlord hereby affirms by execution of this Amendment
that the Lease is in full force and effect and Landlord does not have any
presently existing claims against Tenant under the Lease. There are no defaults
of Tenant under the Lease and there are no existing circumstances which with the

         12. Except as set forth in this Amendment, the Lease remains in full
force and effect. All references in the Lease to "this Lease" shall be deemed
references to the Lease as modified by this Amendment.

         13. This Amendment is contingent upon and shall not be effective until
receipt of written approval from Bank One, Arizona, N.A., Landlord's lender
("LENDER"). Landlord shall use commercially reasonable efforts following the
execution of this Amendment by Landlord and Tenant to obtain Lender's approval
on or before August 31, 1997, and upon receipt thereof will promptly provide a
copy of such approval to Tenant. In the event that Landlord is unable to obtain
such approval on or before August 31, 1997, Tenant shall have the right, as its
sole and exclusive remedy to terminate this Amendment upon written notice to
Landlord on or before September 10, 1997, which termination shall be effective
immediately upon receipt thereof by Landlord, and, upon such termination
Landlord shall reimburse Tenant for Tenant's actual, out-of-pocket costs related
to this Amendment.

conditions of the Lease.

                  6. Tenant hereby affirms by execution of this Second Amendment
