Said leasing is upon and subject to the terms, covenants and conditions set
forth in this Lease. Tenant agrees, as a material part of the consideration
for this Lease, to keep and perform each and all of said terms, covenants and
conditions by it to be kept and performed. Tenant further agrees that this
Lease is made upon the condition of such performance.

1.   TERM

     (a)  The term of this Lease shall be 60 months (unless sooner terminated

October, 2004.

     (b)  If the Landlord is unable to deliver possession of the Leased
Premises within 90 days of the projected Commencement Date, this Lease shall be
voidable at Tenant's option. In no event shall Tenant be liable for any rent
until such time as Landlord can and does deliver possession of the Leased
Premises to Tenant. The date upon which Landlord can and does deliver possession
of the Leased Premises to Tenant shall be the Commencement Date of this Lease.
If delivery of possession occurs on other than the first day of a calendar
month, rental for the remainder of that month shall be paid by Tenant on a pro
rata basis.

2.   RENT

     Tenant agrees to pay as base rent the sum of forty six thousand eight
hundred eighty eight 13/100 dollars ($46,888.13) per month for each and every
month of this Lease (the "Base Monthly Rent"), subject to adjustment, as
provided in paragraph 3 hereof, payable in advance on the first day of each
month, without offset, commencing with the Commencement Date of this Lease. In
addition to Base Monthly Rent, all other sums of any type or kind required to

               heating, ventilating and air conditioning costs, electricity or

signs and equipment, lighting, sanitary control and garbage removal, curbing
and fencing maintenance, glass maintenance and window cleaning;

          (F)  the cost of the Landlord's insurance in types and amounts as may
reasonably be carried by a prudent owner, or as required by any lender of
Landlord,

          (G)  cost of each "Major Expenditure" (as hereinafter defined) as
amortized over the period of the economic life of the Major Expenditure, but
not to exceed fifteen (15) years, using equal monthly installments of principal
and interest at the rate announced by Wells Fargo Bank as its prime rate at the
time of expenditure, plus one-half percent (1/2%) where "Major Expenditure"
shall mean any single expenditure incurred during or subsequent to the calendar
year in which the Lease commences, for modifications or additions to the
Building, the Parking Garage, or the Site if one of the principal purposes of
such modification or addition was to reduce energy consumption or operating
expenses, or was required by governmental law or regulations; and

          (H)  an administrative or property management fee. The property
management fee shall be three percent (3%) of the gross collected rents from
the Building, the Parking Garage and the Site. The salaries and wages of those
persons referred to in subparagraph 3(b)(ii)(A) are not deemed to be part of
the property management services for purposes of the limitation contained
in this subparagraph.

(iii)     If, in any such calendar year the average Building occupancy is less
          than ninety-five percent (95%) of the rentable area thereof during the
          entire calendar year, "Operating Expenses" shall mean the amount
          obtained by adjusting the actual Operating Expenses that vary with
          occupancy for such calendar year as if the Building had been
          ninety-five percent (95%) occupied during the whole of such calendar
          year.

(iv)      "Tenant's Percentage" means the percentage determined by converting a
          fraction, the numerator of which is the rentable area of the Leased
          Premises from time to time, and the denominator of which is the total
          rentable area of the Building from time to time. Landlord and Tenant
          acknowledge that Tenant's Percentage as of the Commencement Date is
          twenty five point forty eight percent (25.48%) and is based on the
          actual rentable area of the Leased Premises and rentable area of the
          Building as of the Commencement Date.

     (c)  Landlord shall, each year during the term of this Lease, deliver to
Tenant a statement of estimated Operating Expenses for the following calendar
year. If the estimated Operating Expenses are projected to exceed the Base
Operating Expenses, Tenant shall pay to Landlord with each payment of the Base
Monthly Rent, as additional rent hereunder, an amount equal to one-twelfth
(1/12) of the estimated Operating Expenses for such calendar year (less the
Base Operating Expenses) multiplied by the Tenant's Percentage.

(d)  Landlord shall, each year during the term of this Lease, deliver to Tenant
a statement of the actual Operating Expenses for the preceding calendar year,
but Landlord's failure to deliver such statement shall not preclude Landlord's
recovery of Operating Expenses. If the actual Operating Expenses for a calendar
year exceed the Base Operating Expenses for such calendar year, Tenant shall,
upon the receipt of such statement, pay to Landlord an amount equal to the
actual Operating Expenses (less the Base Operating Expenses) multiplied by the
Tenant's Percentage; provided, however, that payments by Tenant, if any, of
estimated Operating Expenses pursuant to this Section 3 shall be credited
against the amount due. The actual Operating Expenses shall be prorated, if
applicable, in the case of the first and last years of the term of the Lease. If
the actual Operating Expenses for such calendar year are greater than the Base
Operating Expenses but are less than the estimated Operating Expenses for such
calendar year collected by Landlord pursuant to this Section 3; then Tenant
shall receive a credit against future monthly payments of Tenant's Percentage of
estimated Operating Expenses in an amount equal to the excess of Tenant's
Percentage of estimated Operating Expenses.

     (e)  Notwithstanding anything to the contrary contained herein, the
amount of rent payable under this Lease shall never be less than the Base
Monthly Rent.

4.   PARKING

     (a)  Tenant shall be allocated in the Parking Garage 84 covered reserved
spaces. The charge for the covered reserved spaces shall be no charge. Landlord
will provide reasonable means of identifying and controlling vehicles
authorized to be parked in the reserved and unreserved areas of the Parking
Garage. Landlord may make, modify and enforce rules and regulations. Landlord
shall maintain a total parking supply of 5 spaces per 1,000 rentable square
feet of Leased Premises.

conditions on Tenant's part to be performed and observed in this Lease as well
as in all extensions and renewals hereof. Such deposit shall be returned to
Tenant at the termination of this Lease if Tenant has discharged its
obligations to Landlord in full. Landlord shall not be required to keep this
security deposit separate from its general funds and Tenant shall not be

the contractor's written agreement to not deviate from the plans and
specifications without Landlord's written consent; (ii) obtain the contractor's
written agreement that it must look only to the Tenant for the payment of any
charge for such work and that the contractor has included a provision to that
effect in each subcontract and material contract for such work to be performed;
and (iii) at Landlord's election, obtain and record a payment bond pursuant to
A.R.S. section 33-1003 or any successor statute. All alterations, improvements
or additions shall become Landlord's property and shall remain upon the Leased
Premises at the termination of this Lease without compensation to Tenant;

     * Such consent shall not be unreasonably withheld

8. LIENS

     Tenant shall keep the Leased Premises free from any liens arising out of
any work performed, materials furnished, or obligations incurred by Tenant. In
the event that Tenant shall not, within ten (10) days after receiving notice of
the imposition of any such lien, cause the same to be released of record by
payment or posting of a proper bond, Landlord shall have, in addition to all
other remedies provided herein and by law, the right to cause the same to be
released by such means as it shall deem proper, including payment of the claim
giving rise to such lien. All such sums paid by Landlord and all expenses
incurred by it in connection therewith including without limitation costs of
suit and attorney's fees shall be considered additional rent and shall be
payable by Tenant on demand with interest at the rate of ten percent (10%) per
year.

interfere with other tenants in the Building or use or allow the Leased Premises
to be used for any unlawful, or other purpose. Tenant agrees to comply with all
applicable laws, ordinances and regulations and private covenants, conditions
and restrictions now or hereafter in force in connection with its use of the

<PAGE>   9
     beneath the Leased Premises beyond the load limit established by Landlord,
or knowingly permit any explosives to enter the Building. Tenant shall not do

anything therein which will in any way increase the fire insurance premium or
other insurance premium upon The Building.

10.  LANDLORD SERVICES

     Landlord agrees to furnish to the Leased Premises subject to the Standards
for Utilities and Services attached hereto as Exhibit "C" and by this reference
made a part hereof, water, electricity, heating, and air conditioning suitable
for the specified use and occupation of the Leased Premises, janitorial
service, and elevator service. Tenant agrees to abide by all regulations and
requirements that Landlord may prescribe for the proper functioning and
protection of the heating, ventilating, and air conditioning system. Landlord
may make, modify or enforce the Standards for Utilities and Services at any
time provided that such failure does not exceed five (5) days. Landlord shall
have no liability, and Tenant shall not be entitled to any abatement or
reduction of rental, by reason of Landlord's failure to furnish any services
when such failure is caused by accident, breakage, repairs, strikes, lockouts,
labor disturbances or labor disputes, or by any other cause, similar or
dissimilar, beyond the reasonable control of Landlord.

11.  RULES AND REGULATIONS

     Tenant agrees to abide by all rules and regulations of this Building
imposed by Landlord, a copy of which are attached hereto as Exhibit "D" and by
this reference made a part hereof. These regulations are imposed for the
cleanliness, good appearance, proper maintenance, good order and reasonable use
of the Leased Premises and the Building, and as may be necessary for the proper
enjoyment of the Building by all tenants and their clients, customers and
employees. The rules and regulations may be changed by the Landlord from time
to time, and shall become effective after reasonable notice to Tenant. Failure
of Tenant to comply with the Building Rules and Regulations shall constitute a
default under this Lease.

12.  TAXES

     Tenant shall, in addition to and at the same time as the payment of the
Base Monthly Rent under this Lease, pay to Landlord the amount of any rental,
or sales, tax (but excepting Landlord's income tax) now or hereafter imposed by
any taxing authority upon Landlord or upon Landlord's receipt of the Base
Monthly Rent and all other amounts payable by Tenant pursuant to the terms of
this Lease.

<PAGE>   10
14.  UNTENANTABILITY

     If the Leased Premises are made untenantable in whole or in part by fire
or other casualty, the Base Monthly Rent, until repairs shall be made or the
Lease terminated as hereinafter provided, shall be apportioned on a per diem
basis according to the part of the Leased Premises which is usable by the
Tenant, if, but only if, such fire or other casualty was not caused by the
fault or negligence of the Tenant, its contractors, agents, or employees. If
such damage shall be so extensive that the Leased Premises cannot, in
Landlord's opinion, be restored to tenantability by the Landlord within a
period of sixty (60) days, either party shall have the right to cancel this
Lease by notice to the other given at any time within sixty (60) days after the
date of such damage; except that if such fire or casualty resulted from the
Tenants' fault or negligence, the Tenant shall have no right to cancel. If a
portion of the Building other than the Leased Premises shall be so damaged that
in the opinion of the Landlord the Building should be restored in such a way as
to alter the Leased Premises materially, the Landlord may cancel this Lease by
notice to the Tenant given at any time within sixty (60) days after the date of
such damage. If more than twenty-five percent (25%) of the Building is made
untenantable by fire or other casualty (regardless of whether the Leased
Premises are untenantable), Landlord may terminate this Lease by written notice
to Tenant within one hundred twenty (120) days after the date of such casualty.
In the event of giving effective notice pursuant to this Section, this Lease
and the term and the estate hereby granted shall expire on the date fifteen
(15) days after the giving of such notice as fully and completely as if such
date were the date hereinafter set for the expiration of the term of this
Lease. In the event neither Landlord nor Tenant cancels the Lease, within sixty
(60) days and Landlord wishes to effect such restoration, the Landlord shall,
promptly after adjustment of any relevant insurance claims, commence such
restoration at Landlord's expense. In no event shall Landlord be required to
expend funds in excess of its insurance recovery on such restoration.

15.  EMINENT DOMAIN

     In the event any portion of the Leased Premises, the Building, the Parking
Garage, or the Site is taken under eminent domain proceeding, Tenant shall have
no right, title or interest to any award for such taking, except for fixtures
and improvements installed by Tenant, if any.

16.  ASSIGNMENT AND SUBLEASE

     Tenant shall not, either voluntarily or by operation of law, sell, assign,
hypothecate or transfer this Lease, or sublet the Leased Premises or any part
thereof,

                                       10
<PAGE>   11
without the prior written consent of Landlord in each instance. Landlord's
consent to an assignment or sublease shall not be withheld, provided the
proposed assignee or sublessee is reasonably satisfactory to Landlord as to
credit and character and will occupy the Leased Premises for office purposes
consistent with  Article 9 of this Lease and Landlord's commitments to other
tenants. Any sale, assignment, mortgage, transfer or subletting of this Lease
which is not in compliance with the provisions of this Article 16 shall be void
and shall be a material default of this Lease by Tenant. The consent by Landlord
to any assignment or subletting shall not be construed as relieving Tenant from
obtaining the express written consent of Landlord to any further assignment or
subletting or as releasing Tenant from any liability or obligation hereunder,
whether or not then accrued. The Landlord reserves the right, should the Tenant
request such assignment or subletting, to release the Tenant from the terms and
provisions of this Lease and the Landlord shall have thirty (30) days to make
such determination. Should the Landlord exercise this right, then the Lease
shall terminate as of the date notice is given to Tenant.

     Tenant shall make no profit on a sublease or assignment of this Lease and
any increase in rent, bonus or other fee charged or received, which is higher
than, or in addition to, the Monthly Base Rent and other sums due under this
Lease shall be paid to Landlord.

17.  ACCESS

     Landlord and its agents shall have the right to enter the Leased Premises
at all reasonable times and provided that such entry does not unreasonably
interfere with Tenant's business for the purpose of examining or inspecting the
same, showing the same to prospective purchasers or tenants of the Building, and
as necessary to perform Landlord's obligations under this Lease. Landlord may
erect, use, and maintain scaffolding, pipes, conduits, and other necessary
structures in and through the Leased Premises where reasonably required by the
character of the work performed, provided that the business of Tenant shall not
be unreasonably interfered with. If Tenant shall not personally be present to
open and permit an entry into the Leased Premises at any time when such entry by
Landlord is necessary or permitted hereunder, Landlord may enter by means of a
master key or, in emergencies, may enter forcibly, without liability to Tenant.

18.  SUBORDINATION AND ATTORNMENT

     (a) This Lease is automatically junior, subject and subordinate to all
ground leases, mortgages, deeds of trust and other security instruments of any
kind now or hereafter covering the Site, the Building, the Parking Garage and/or
the Leased Premises or any portion thereof or interest therein. Notwithstanding
the foregoing, Tenant covenants and agrees to execute and deliver upon demand
such further instruments evidencing such subordination of this Lease as may be
requested by Landlord. If any mortgage, trustee, or ground lessor shall elect to
have this Lease prior to the lien of a mortgage, deed of trust or ground lease,
and shall give written notice thereof to Tenant, this Lease shall be deemed
prior to such mortgage, deed of trust or ground lease, whether



                                       11
<PAGE>   12
this Lease is dated prior to or subsequent to the date of said mortgage, deed of
trust or ground lease or the date of recording thereof.

     (b) In the event of the enforcement by any mortgagee, trustee under any
deed of trust or holder of any other security instrument of the remedies
provided for by law or by such mortgage, deed of trust or other security
instrument, Tenant will, if requested by such mortgagee, trustee, or beneficiary
or by any person succeeding to the interest of Landlord as the result of said
enforcement, automatically become the tenant of any such successor in interest,
without any change in the terms or other provisions of this Lease. Upon request
by said successor in interest, the Tenant shall execute and deliver an
instrument or instruments confirming its attornment. Nothing herein shall be
construed as a subordination of, or agreement to subordinate, the lien and
charge of any mortgage, deed of trust or other security instrument to the rights
or leasehold estates of the Tenant under this Lease.

19.  SALE

     This Lease shall not be affected by any sale or conveyance by Landlord of
the Building containing the Leased Premises. This Lease shall not be affected by
any such sale, and Tenant agrees to attorn to the purchaser of the Building and
deliver to the purchaser an offset statement and an estoppel certificate in such
form as Landlord may request. If any security deposit has been made by Tenant,
Landlord may transfer such security deposit to the purchaser, and thereupon
Landlord shall be discharged from any further liability in reference thereto.

20.  INDEMNIFICATION OF LANDLORD

     (a) Tenant shall hold Landlord harmless from, indemnify and defend Landlord
against any and all claims for liability for any injury (including death) or
damage to any person or property whatsoever (i) occurring in, or on the Leased
Premises or any part thereof, or (ii) occurring in or about the Building when
such injury or damage has been caused solely the act, neglect, fault or omission
of Tenant, its agents, servants, or employees, and from all costs, attorneys'
fees, expenses and liabilities incurred as a result of any such claim or any
action or proceeding brought thereon; and in case any action or proceeding be
brought against Landlord by reason of any such claim, Tenant, upon notice from
Landlord, shall defend the same at Tenant's expense. Tenant, as a material part
of the consideration to Landlord,



                                       12
<PAGE>   13
hereby assumes all risk of damage to property or injury to persons (including
death), in, upon or about the Leased Premises from any cause which does not
result from the gross negligence or willful misconduct of Landlord and Tenant
hereby waives all claims in respect thereof against Landlord.

     (b) Landlord or anyone authorized to act for Landlord shall not be liable
for any damage to property entrusted to employees of the Building, nor for loss
of or damage to any property by theft or otherwise, except for the injury or
damage caused by the negligence or willful misconduct of Landlord's agents,
employees, invitees, or customers. Tenant shall give prompt notice to Landlord
of any fire, accident or defect discovered within the Leased Premises or the
Building.

     (c) The provisions of this Section 20 shall survive the expiration or
termination of this Lease with respect to any claims or liability occurring
prior to such expiration or termination.

21.  TENANTS INSURANCE, WAIVER OF SUBROGATION

     (a) Tenant agrees to carry at its own expense throughout the term of the
Lease, commercial general liability insurance insuring Tenant and Landlord, as
an additional insured, against all claims, demands, or actions arising out of,
or in connection with, Tenant's use or occupancy of the Leased Premises or by
the condition of Leased Premises. Such insurance shall have a combined single
limit of liability of $2,000,000.00 for bodily injury or death and property
damage. The limits of said insurance shall not, however, limit the liability of
Tenant hereunder. Said insurance shall be primary and not contributing with any
insurance maintained by Landlord and shall include lessor's protective liability
coverage and shall also include contractual liability coverage covering all
indemnification obligations of Tenant under this Lease. Tenant shall deliver a
Certificate of Insurance, in form reasonably acceptable to Landlord, to Landlord
prior to the date of occupancy of the Leased Premises evidencing said insurance
policy and stating that the insurer agrees to give no less than thirty (30) days
prior written notice to Landlord in the event of modification or cancellation
thereof.

     (b) Tenant shall be responsible for its own personal property insurance.

     (c) Landlord and Tenant each hereby release the other from any and all
liability or responsibility for any direct or consequential loss, injury or
damage to the Leased Premises, or its contents, caused by fire or any other
casualty, during the term of this Lease, even if such fire or other casualty may
have been caused by the negligence (but not the willful act) of the other party
or one for whom such party may be responsible. Inasmuch as the above mutual
waivers will preclude the assignment of any aforesaid claim by way of
subrogation (or otherwise) to an insurance company (or any other


                                       13
<PAGE>   14
person), each party hereto agrees if required by said policies to give each
insurance company which has issued to it fire and other property insurance,
written notice of the terms of said mutual waivers, and to have said insurance
policies properly endorsed, if necessary, to prevent the invalidation of said
insurance coverage by reason of said waivers.

22.  ATTORNEY'S FEES

     In the event of any legal action or proceeding brought by either party
against the other arising out of this Lease, the prevailing party shall be
entitled to recover reasonable attorneys' fees incurred in such action and such
amount shall be included in any judgment rendered in such proceeding.

23.  WAIVER

     No waiver by Landlord of any provision of this Lease or of any breach by
Tenant hereunder shall be deemed to be a waiver of any other provision hereof,
or of any subsequent breach by Tenant of the same or any other provision.
Landlord's consent to or approval of any act by Tenant requiring Landlord's
consent or approval shall not be deemed to render unnecessary the obtaining of
Landlord's consent to or approval of any subsequent act of Tenant. No act or
thing done by Landlord or Landlord's agents during the term of this Lease shall
be deemed an acceptance of a surrender of the Leased Premises, unless done in
writing signed by Landlord. The delivery of the keys to any employee or agent of
Landlord shall not operate as a termination of this Lease or a surrender of the
Leased Premises.

24.  NOTICES

     All notices, demands or other communications in this Lease provided to be
given, made or sent by either party hereto to the other shall be deemed to have
been duly given, made or sent when made in writing and deposited in the United
States mail, certified or registered, postage prepaid, and addressed as follows:

<PAGE>   15
     The address to which any notice, demand or other writing may be given, made
or sent to either party may be changed by written notice given by such party as
above-provided.

25.  INSOLVENCY OR BANKRUPTCY

     The appointment of a receiver to take possession of all or substantially
all of the assets of Tenant, or an assignment by Tenant for the benefit of
creditors, or any action taken or suffered by Tenant under any insolvency,
bankruptcy, or reorganization act, or if any guarantor of this Lease dies,
revokes, or otherwise terminates, or purports to revoke or otherwise terminate
(by operation of law or otherwise) any guaranty of all or any portion of
Tenant's obligation under this Lease, shall at Landlord's option, constitute a
breach of this Lease by Tenant. Upon the happening of any such event, or at any
time thereafter, this Lease shall terminate five (5) days after written notice
of termination from Landlord to Tenant. In no event shall this Lease be assigned
or assignable by operation of law and in no event shall this Lease be an asset
of Tenant in any receivership, bankruptcy, insolvency, or reorganization
proceedings.

26.  DEFAULT

     (a)  In the event Tenant fails to pay any rental due hereunder or fails to
keep and perform any of the other material terms or conditions hereof, or
otherwise breaches this Lease or defaults hereunder, time being of the essence,
or in the event of the taking by execution or judgment or other process of law
of all or any part of the Tenant's interest in this Lease, then ten (10) days
after receipt of written notice of default from Landlord, Landlord may, if such
default has not been corrected, resort to any and all legal remedies or
combination of remedies which Landlord may desire to assert including, but not
limited to one or more of the following: (1) lock the doors of the Leased
Premises and exclude Tenant therefrom; (3) enter the Leased Premises and remove
all persons and property therefrom; (4) declare this Lease at an end and
terminated; (5) sue for the rent due and to become due under this Lease; (6)
sue for any damages sustained by Landlord; and (7) continue this Lease in
effect and relet the Leased Premises on such terms and conditions as Landlord
may deem advisable with Tenant remaining liable for the Base Monthly Rent and
other sums due hereunder plus the reasonable cost of obtaining possession of
the Leased Premises and of any repairs and alterations necessary to prepare the
Leased Premises for reletting, and the cost of reletting. No action of Landlord
shall be construed as an election to terminate this Lease unless written notice
of such intention be given to Tenant. No payment by Tenant or receipt by
Landlord of a lesser amount than the Monthly Base Rent and other sums due
hereunder shall be deemed to be other than on account of the earliest rent or
other sums due, nor shall any endorsement or statement on any check or
accompanying any check or payment be deemed an accord and satisfaction; and
Landlord may accept such check or payment without prejudice to Landlord's right
to recover the balance of such rent or other sum or pursue any other remedy
provided in this Lease. Notwithstanding the foregoing to the contrary, the
abandonment of the Leased


                                       15
<PAGE>   16
Premises by Tenant shall be an incurable default hereunder, entitling Landlord
to immediately resort to the remedies described above.

     (b)  If Landlord shall default in performing its obligations under this
Lease, Tenant shall give Landlord written notice of the deficiency, and Landlord
shall have ten (10) days after receipt of such notice to correct the same;
provided, however, that if the nature of Landlord's obligation is such that more
than ten (10) days are required for performance, then Landlord shall not be in
breach if Landlord commences performance within such ten (10) day period and
thereafter diligently prosecutes the same to completion. In no event shall
Tenant have the right to terminate this Lease as a result of Landlord's breach,
and Tenant's remedies shall be limited to damages and/or an injunction.

     (c)  Tenant shall look solely to the equity of Landlord in the Building,
and the rents, issues and profits derived therefrom, and to no other assets of
Landlord, for the satisfaction of the remedies of Tenant in the event of a
breach by Landlord. Tenant will not seek recourse against the individual
shareholders, directors, officers, employees or agents of Landlord or against
the individual members or managers of Landlord's manager or any successors in
interest or any of their personal assets for such satisfaction. It is mutually
agreed that this clause is and shall be considered an integral part of this
Lease.

27.  INTEREST ON TENANT'S OBLIGATIONS AND LATE CHARGES

     (a)  Any amount due from Tenant to Landlord which is not paid when due
shall bear interest of ten percent (10%) per annum until paid, but the payment
of such interest shall not excuse nor cure the default.

     (b)  Tenant acknowledges that late payment of the Base Monthly Rent or any
other sum required by this Lease to be paid by Tenant to Landlord will cause
Landlord to incur costs not contemplated by this Lease, the exact amount of such
costs being extremely difficult and impracticable to fix. Therefore, if any
payment due from Tenant is not received by Landlord within five (5) calendar
days after its due date, Tenant shall pay to Landlord an additional sum of three
hundred dollars ($300) as a late charge. In addition to the above-described late
charge, Tenant shall pay to Landlord fifty dollars ($50) for processing and
accounting costs together with interest on such amount at the rate specified
above for each occasion that a rental check presented to Landlord by Tenant is
returned by Tenant's bank for insufficient funds or for any other reason.

28.  HOLDING OVER

     No holding over by Tenant after the term of this Lease shall operate to
extend the Lease. In the event of any unauthorized holding over, such occupancy
shall be a tenancy at sufferance and Tenant shall indemnify Landlord against all
claims for damages by any other tenant to whom Landlord may have leased all or
any part of the Leased Premises covered hereby effective upon the termination of
this Lease. During any such tenancy at sufferance, Tenant shall pay a Base
Monthly Rent equal to 150% of the most recent Base


                                       16
<PAGE>   17
Monthly Rent then in effect plus all other charges payable hereunder. Such
tenancy shall otherwise be upon all the terms hereof applicable to such a
tenancy at sufferance.

29.  TIME

     Time is of the essence of this Lease in each and all of its provisions.

30.  BROKERS

     Tenant warrants that it has had no dealing with any real estate broker or
agent in connection with the negotiation of this Lease, excepting only Bill
Blake; Lee & Associates and any broker or agent that Landlord may have employed.
If but only if this Lease is fully executed and Tenant actually takes possession
of the Leased Premises, Landlord shall pay to such brokers or agents a
commission set forth in a separate agreement between Landlord and such brokers
or agents. Except for such brokers or agents, Tenant knows of no other real
estate broker or agent which is or may be entitled to a commission in
connection with this Lease. Tenant agrees to indemnify and hold harmless
Landlord from any claims for commission by brokers or agents not mentioned in
this paragraph.

31.  RECORDATION

     Tenant shall not record this Lease or a short form memorandum thereof
without the prior written consent of Landlord.

32.  BUILDING NAME

     Tenant shall not use the name of the Building or the development in which
the Building is situated for any purpose other than the address of the business
to be conducted by Tenant in the Leased Premises.

33.  SIGNS

     (a)  Landlord shall have the sole and absolute discretion over all matters
relating to on-premise signs relating to the Building and other Tenant
identification signs and facilities which are intended to be seen by the public
from roads, sidewalks, pedestrian areas and adjoining structures in the
vicinity of the Building.

     (b)  See Addendum

34.  CHOICE OF LAW

     This Lease shall be governed by the Laws of the State of Arizona.

35.  ESTOPPEL CERTIFICATE OR THREE-PARTY AGREEMENT

     At Landlord's request, Tenant will in addition to any other statements or
certificates required to be executed by Tenant, execute and deliver within ten
(10)

                                       17
<PAGE>   18
working days, an estoppel certificate and/or three-party agreement among
Landlord, Tenant and any third party dealing with Landlord certifying as to such
facts (if true) and agreeing to such notice provisions and other matters as
such third party may reasonably require in connection with the business
dealings of Landlord and such third party.

36.  ADDITIONAL CONSTRUCTION

     Tenant acknowledges that buildings other than the Building may be
constructed within the project of which the Building is a part, and, in
connection with such construction, Tenant shall permit Landlord and/or any
owner of the land upon which such additional buildings are being constructed,to
enter the Leased Premises to erect scaffolding and/or protective barriers
around the Leased Premises (but not so as to preclude entry thereto) and to do
any act or thing necessary for the safety or preservation of the Building.
Landlord shall not be liable in any such case for any inconvenience,
disturbance, loss of business or any other annoyance arising from any such
construction, but Landlord shall use its reasonable efforts to see that Landlord
or any adjoining owner will conduct such construction as consistently as
possible with accepted construction practices, so as to minimize inconvenience,
annoyance and disturbance to Tenant.

37.  DEFINED TERMS AND MARGINAL HEADINGS

     The words "Landlord" and Tenant" as used herein shall include the plural as
well as the singular. If more than one person is named as Tenant, the
obligations of such persons are joint and several. The marginal headings and

effect upon the construction or interpretation of any part hereof.

38.  TENANT'S RESPONSIBILITY REGARDING HAZARDOUS SUBSTANCES

this Lease, shall include, without limitation, flammables, explosives,

     and shall furnish Tenant with space on the directory for the identification
     of the Tenant. Tenant shall also be permitted to maintain a sign over its
     reception desk within the Leased Premises.

39.  Lease Term Extension

     Provided Tenant is not in default under the terms and conditions of the
     Lease, Tenant may negotiate an extension of the Lease for five (5)
     additional years. The rental rate and other material terms and conditions
     are subject to renegotiations under the then prevailing market.

     Tenant shall notify Landlord in writing, not more than six (6) months nor
     less than four (4) months prior to the lease expiration of its desire to
     extend the Lease.

     If Landlord and Tenant are unable to agree on the final lease extension

     further right to the Leased Premises.

          calendar year of the Term. If Landlord and Tenant agree that the
          examination discloses that an item of Additional Rent billed to Tenant
          was incorrect the appropriate party shall pay the other party the
          deficiency or overpayment, as applicable. All costs and expenses of
          the examination shall be paid for by the Tenant.

     41.  Telecommunications Link

          The Landlord understands that IIS needs telecommunications services
          between their existing suite at 1501 W. Fountainhead Parkway and the
          leased premises located at 2625 S. Plaza Drive. In order to
          accommodate this need the Landlord shall allow for the construction of
          new telecommunications facilities (i.e. underground cabling and
          equipment in tenant's telecommunications rooms), between 1501 W.
          Fountainhead Parkway and 2625 S. Plaza Drive. The cost for the above
          construction shall be paid by the approved telecommunications vendor
          or IIS. The Landlord shall not be responsible for any installation
          costs.

          In the event that the Landlord's telecommunications vendor is unable
          to fulfill IIS's need for telecommunications services between the two
          buildings the Landlord shall allow the Tenant's vendor to utilize
          existing conduit and/or perform necessary construction between the
          buildings in order to allow IIS to install the telecommunications
          facilities. The cost for the above construction shall be paid by IIS.

          All vendors and all proposed construction must be approved by the
          Landlord prior to the start of any construction.

          It is understood and agreed to that the Landlord is making no
          representations or warranties regarding the condition of the existing
          underground conduit(s) or that the same are suitable for the Tenant's
          desired or intended use.

          It is further understood and agreed to that, except for the gross
          negligence or willful misconduct of the Landlord or its agents or
          employee, the Landlord shall not be responsible or liable to the
          Tenant for the care, maintenance, or upkeep of the system, nor shall
          Landlord be held responsible or liable for any damage to the system,
          wear and tear of the system, or failure of the system.

     42.  Space Planning

          Landlord shall provide a space planning allowance of $.10 per rentable
          square foot, payable to Tenant's design services firm.

     43.  Right of First Refusal on Leased Premises Located at 2400 South
          MicroAge Way

          Provided Tenant is not in default under the terms and conditions of
          the Lease Agreement, Tenant shall have the Right of First Refusal to
          lease up to 34,678 rentable square feet of space located at 2400 South
          MicroAge Way, Tempe, AZ. Upon receipt in writing from Landlord of a
          copy of a bona fide offer from a third party, or existing tenant of
          the Premises, on the refusal space, Tenant shall have ten (10) days in
          which to notify Landlord, in writing, of its election to lease the
          space upon the same terms and conditions and those contained within
          the third party or existing tenant offer. Tenant's failure to notify
          Landlord within the above described time frame will be deemed to be a
          waiver of this Right of First Refusal.
