vaults, and other improvements of such a nature as not likely to be generally
usable (in Landlord's reasonable determination) by likely future tenants of the
Building (collectively, the "Specialized Improvements"); provided that if Tenant
shall request of Landlord, in writing, at the time of approval of Tenant's plans
for Tenant's improvements or alterations whether such improvements or
alterations constitute Specialized Improvements for purposes of this Section
2.4, Landlord shall use good faith efforts to promptly determine at that time,
if reasonably possible, whether such improvements or alterations constitute
Specialized Improvements, Reserved Improvements or Standard Improvements. If
Landlord determines, in good faith, that it cannot make such "Specialized
Improvement" determination at such time, then Landlord may reserve such
determination until the expiration or termination of the Lease (each, a
"Reserved Improvement"). If Landlord subsequently requires removal of the
Reserved Improvement, Tenant shall, upon expiration or termination of the Lease,
remove any such Reserved Improvements and repair all damage caused by such
removal. (If after receiving a request from Tenant for a classification of
certain Improvement Landlord determines that such improvements are not
Specialized Improvements or Reserved Improvements, then such improvement shall
be a standard improvement that Tenant is not required to remove (each, a
"Standard Improvement"). Tenant shall be liable to Landlord for all costs
incurred by Landlord in returning the Leased Premises, the Building and the
Property to the required condition, together with interest (at the maximum rate
allowed by law) on all costs so incurred from the date paid by Landlord until

Tenant of a bill for the same. Tenant shall indemnify Landlord against loss or
liability resulting from delay by Tenant in surrendering the Leased Premises,
Building, and Property, including, without limitation, any claims made by any
succeeding tenant or any losses to Landlord with respect to lost opportunities
to lease to succeeding tenants.

                                    SECTION 3
                               TERM OF THE LEASE

            3.1 Lease Term. The term "Initial Lease Term" shall mean the term of
this Lease, which shall be for a period of One Hundred Twenty (120) full
calendar months (plus the partial month, if any, immediately following the
Commencement Date), commencing on the Commencement Date and ending at midnight
on the last day of the One Hundred Twentieth (120th) full calendar month
thereafter, unless this Lease is extended or sooner terminated according to its
terms or by mutual agreement. The term "Lease Term" shall mean the Initial Lease
Term and any extensions thereof.

            3.2 Postponement. If, for any reason, Landlord is unable to deliver
possession of the Premises to Tenant on the Commencement Date, the commencement
of the Lease Term will be postponed, without liability to either party or
affecting the validity of this Lease, and the term shall begin on such date as
Landlord is able to deliver possession of the Leased Premises to Tenant;
provided, that Tenant shall have the right to terminate this Lease without
further liability of Landlord or Tenant if Landlord is unable to deliver
possession of the Leased Premises within one hundred twenty (120) days after the
scheduled Commencement Date of July 15, 2000.

            3.3 Lease Extension.

                (a) Extension. Tenant may, at its option (if it is not then in
default under the Lease beyond any applicable notice and cure period), extend
the Initial Lease Term for an additional sixty (60) month period commencing at
the end of the Initial Lease Term (the "Extended Term"). This option shall be
exercised, if at all, by Tenant's written notice (the "Option Notice") to
Landlord stating Tenant's exercise of its option, delivered not less than one
(1) year (nor more

                                       5
<PAGE>   6

than 15 months) prior to the end of the Initial Lease Term. The Extended Term
shall be upon all terms and conditions of this Lease (but with no further option
to extend) other than the Base Monthly Rental, which shall be the then fair
rental value of the Premises as determined in accordance with Section 3.3(b) and
adjusted in accordance with this Section 3.3(a). The Base Monthly Rental
determined in accordance with Section 3.3(b) shall be increased on the first day
of the second year of the Extended Term and each anniversary thereafter during
the Extended Term by three percent (3%).

                (b) Extended Monthly Rent. If within thirty (30) days after the
Landlord receives the Option Notice the parties agree to what the fair rental
value is, they shall immediately execute an Addendum to this Lease stating the
Base Monthly Rental during the Extended Term. If the parties are unable to agree
on the minimum monthly rent for the Extended Term within such 30-day period,
then within fifteen (15) days after the expiration of that period each party, at
its cost and by giving notice to the other party, shall appoint a commercial
real estate broker ("Appraiser") with at least five years full time commercial
appraisal or brokerage in the Mountain View, California area to appraise and set
the minimum monthly rent for the Extended Term. Each Appraiser shall deliver
their appraisal within thirty (30) days after expiration of the selection of the
Appraisers. If the higher appraisal of rental value is not more than 105% of the
lowest as to the fair rental value, then the average of their appraised value
shall be adopted by the parties. If the higher appraisal is greater than 105% of
the lower then the two Appraisers shall appoint a third Appraiser with similar
qualifications who has not previously represented either party, and who shall
appraise the Leased Premises to determine its fair rental value, and the two
closest in dollar terms of the three offered values shall be averaged and
adopted by the parties as the fair rental value for the purposes of determining
the Base Monthly Rental during the Extended Term. The parties shall equally
share the costs and expenses of the third Appraiser.

                                    SECTION 4
                                      RENT

            4.1 Base Monthly Rental/Prepaid Rent. Subject to the increases
described in Section 4.2, Tenant shall pay Landlord One Hundred Four Thousand
Twenty-Five Dollars ($104,025) as "Base Monthly Rental", in advance, on the
first (1st) day of each calendar month commencing on the Commencement Date and
continuing throughout the Lease Term. The Base Monthly Rental is based on an
amount equal to Three and 65/100 Dollars ($3.65) per square foot multiplied by
the Leased Premises (i.e., initially, agreed and deemed to be 28,500 square
feet). Upon execution of the Lease, Tenant shall deliver to Landlord a check in
the amount of the Base Monthly Rental which Landlord shall apply towards
Tenant's prepayment of the first payment of Base Monthly Rental. For purposes of
the calculation of the Base Monthly Rental (and other amounts under this Lease),
Landlord and Tenant acknowledge and agree that the approximate square footage of
the Leased Premises set forth in Section 1.2 is deemed to be the actual square
footage of the Leased Premises.

            4.2 Annual Adjustment/Adjustment Of Base Monthly Rental. The Base
Monthly Rental shall be increased during the Initial Lease Term as follows: (a)
on the first day of the second year of the Initial Lease Term and each
anniversary thereafter through the fifth year of the Initial Lease Term, Eleven
Cents ($.11) per rentable square foot per year (i.e., $3,135); and (b) on the
first day of the sixth year of the Initial Lease Term and each anniversary
thereafter during the Initial lease Term, Twelve Cents ($.12) per rentable
square foot per year (i.e., $3,420).

            4.3 Additional Rent. In addition to the Base Monthly Rental, Tenant
shall pay to Landlord as additional rent ("Additional Rent") the amounts
described in Sections 4.3, 4.4, 4.5 and 4.6.

                                       6
<PAGE>   7
                (a) Billing. Tenant shall pay, as Rent, Tenant's Pro Rata Share
of Operating Expenses. At Landlord's election, Tenant shall pay Operating
Expenses by one or more of the following methods: (i) paying the invoice for
such expenses submitted to Tenant by Landlord; (ii) Landlord may bill Tenant on
a periodic basis, and Tenant shall pay such bill within thirty (30) days after
receipt thereof; and/or (iii) Landlord may deliver to Tenant a written estimate
of any such expenses which Landlord anticipates will be paid or incurred for the
ensuing calendar or fiscal year, and Tenant shall pay such estimated expenses in
equal monthly installments along with the payment of installments of Base
Monthly Rent. Landlord may change the billing method from time to time in
Landlord's sole discretion on not less than thirty (30) days' notice.

                (b) Operating Expenses. The term "Operating Expenses" shall
mean: (i) all of Landlord's reasonable costs and expenses of operation, repair
and maintenance of the Property (including the Common Area) as determined by
Landlord in accordance with generally accepted accounting principles or other
recognized accounting principles, consistently applied, including, without
limitation, (1) maintenance and other services, (2) power, water, waste disposal
and other utilities (to the extent not paid directly by Tenant), (3) materials
and supplies, (4) maintenance and repairs (including, but not limited to,
non-structural repairs and maintenance of the roof), and (5) the cost of all
insurance (excluding earthquake), which Landlord or Landlord's lender deems
necessary for the Property and any deductible portion of an insured loss; (ii)
costs, or a portion thereof, properly allocable to the Building of any capital
improvements made to the Property by Landlord which comprise labor-saving
devices or other equipment intended to improve the operating efficiency of any
system within the Building (such as an energy management computer system), which
costs shall be amortized over the useful life thereof without interest; and
(iii) costs properly allocable to the Property of any capital improvements made
to the Property by Landlord that are required under any governmental law or
regulation that was not applicable to the Property at the time of the
Commencement Date, or that are reasonably required for the health and safety of
tenants in the Building, the costs, or allocable portion thereof, to be
amortized over the useful life thereof (as determined by generally accepted
accounting principles), together with interest upon the unamortized balance at
the prime rate as announced from time to time by the Wall Street Journal at the
commencement of such capital improvement plus one (1) basis point or such higher
rate as may have been paid by Landlord on funds borrowed for the purpose of
constructing the capital improvements; and (iv) the management fee described in
Section 4.5. Operating Expenses shall not include any of the following items:
depreciation on the Property, including personal property; costs of tenant
improvements; real estate brokers' commissions; professional and administrative
fees (excluding fees to the extent arising from the acts or omissions of
Tenant); and work other than that caused by the acts or omissions of Tenant or
Tenant's agents, employees or contractors, and capital items other than those
referred to in clauses (ii) and (iii) above. For purposes of this Lease,
"capital items" shall mean those items which would be capitalized pursuant to
generally accepted accounting principles.

                (c) Estimated Operating Expenses. During December of each
calendar year during the Term, or as soon thereafter as practicable, Landlord
may give Tenant written notice of Landlord's good faith estimate of the Tenant's
Pro Rata Share of Operating Expenses for the ensuing calendar year. On or before
the first day of each month during the ensuing calendar year, Tenant shall pay
to Landlord one-twelfth (1/12) of the estimated amount; provided, that if notice
is not given in December, Tenant shall continue to pay on the basis of the then
applicable Rent until the month after the notice is given. If at any time it
appears to Landlord that the increased amount payable for the current calendar
year will vary from Landlord's estimate by more than five percent (5%), Landlord
may give notice to Tenant of Landlord's revised estimate for the year, and
subsequent payments by Tenant for the year shall be based on the revised
estimate; provided, that Landlord shall not give notice of a revised estimate
for any year more frequently than once a calendar quarter.

<PAGE>   8
                (d) Adjustments To Operating Expenses. Within one hundred twenty
(120) days after the close of each calendar year of the Lease Term, or as soon
after the one hundred twenty (120) day period as practicable, Landlord shall
deliver to Tenant a statement of the adjustment to the Operating Expenses for
the prior calendar year. If, on the basis of the statement, Tenant owes an
amount that is less than the estimated payments for the calendar year previously
made by Tenant, Landlord shall apply the excess to the next payment of Tenant's
Pro Rata Share of Operating Expenses due (or refund such excess to Tenant within
thirty (30) days if the Lease has terminated). If, on the basis of the
statement, Tenant owes an amount that is more than the estimated payments for
the calendar year previously made by the Tenant, Tenant shall pay the deficiency
to Landlord within thirty (30) days after delivery of the statement. The
statement of the Tenant's Pro Rata Share of Operating Expenses shall be presumed
correct and shall be deemed final and binding upon Tenant unless (i) Tenant in
good faith objects in writing thereto within sixty (60) days after delivery of
the statement to Tenant (which writing shall state, in reasonable detail, all of
the reasons for the objection); and (ii) Tenant pays in full, within thirty (30)
days after delivery of the statement to Tenant, any amount owed by Tenant with
respect to the statement which is not in dispute. Landlord shall provide Tenant
with such supporting information as Tenant may reasonably request in connection
with such statement, at Tenant's sole cost. If Tenant objects to Landlord's
allocation to this Property of the cost of self-insurance or blanket insurance,
such allocation shall nonetheless be presumed correct and shall be deemed final
and binding upon Tenant unless Tenant's timely written objection includes
credible evidence that Landlord could have obtained substantially comparable
insurance coverage for this Property alone at lower cost. If the Tenant objects
in good faith, then such dispute shall be resolved by accountants selected by
the procedure set forth in Section 3.3(b), except that three accountants
selected shall (i) be certified public accountants with at least five (5) years
experience in the commercial real estate industry and (ii) determine by majority
vote whether the Landlord's or Tenant's statement is deemed correct.

            4.4 Additional Rent/Real Property Taxes. Tenant shall pay, as Rent,
the Tenant's Pro Rata Share of Real Property Taxes in accordance with Section 6,
which Tenant's Pro Rata Share is initially agreed to be One Hundred Percent
(100%) unless and until Tenant leases less than 100% of the Building. Tenant
shall also pay as Additional Rent to Landlord an amount equal to Landlord's
share of consideration received by Tenant for assignments and sublettings, legal
fees and costs that Tenant is obligated to pay or reimburse to Landlord, and any
other reimbursement items under this Lease.

            4.5 Property Management Fee. Landlord shall provide property
management services, including management of the Common Area (if any),
supervision of Operating Expenses and general management and administrative
services. In consideration for Landlord's property management services, Tenant
shall pay Landlord a property management fee equal to three and one-half percent
(3.5%) of the Base Monthly Rental (the "Property Management Fee"). The Property
Management Fee shall be paid in accordance with Section 4.8.

            4.6 Late Payment. Any sum of Base Monthly Rental or Additional Rent
payable under this Lease by Tenant that is not paid on or before the fifth (5th)
day of the month shall be subject to a late charge equal to five percent (5%) of
the late payment; provided that Landlord shall provide Tenant with one (1)
written notice of nonpayment per calendar year before imposing the late charge,
which charge shall be applied on the fifth (5th) day after the date of such
written notice.

            4.7 Security Deposit. Upon the execution of this Lease, Tenant shall
deliver to Landlord as a security deposit One Hundred Four Thousand Twenty-Five
Dollars ($104,025) (the "Security Deposit"). Landlord shall hold the Security
Deposit as security for Tenant's faithful performance of all the terms of this
Lease by it to be observed and performed. Tenant shall not mortgage, assign,
transfer, or encumber the Security Deposit without Landlord's prior written
consent. Any of these acts by Tenant shall be without effect and shall not be
binding upon

                                       8
<PAGE>   9

Landlord. If Tenant is in default pursuant to Section 12 of this Lease beyond
the applicable notice and cure period, then Landlord may, at Landlord's option
and without prejudice to any other remedy, appropriate and apply the entire
Security Deposit or so much of it as may be necessary to remedy such default or
to compensate Landlord for loss or damage sustained by Landlord as a result of
such default. Under such circumstances, Landlord may require Tenant to restore
the Security Deposit to its original amount. If Tenant complies with all of the
terms and promptly pays all amounts when due under the Lease, the Security
Deposit, shall be returned in full to Tenant within thirty (30) days after the
end of the Lease Term. If bankruptcy or other debtor-creditor proceedings
against Tenant occur, the Security Deposit shall be offset against any unpaid
amounts due under this Lease. Landlord shall not be deemed a trustee of the
Security Deposit, and Landlord may use the Security Deposit in Landlord's
ordinary business and shall not be required to segregate it from general
accounts. Tenant shall not be entitled to any interest on the Security Deposit.
If Landlord transfers the Building and/or Property during the Lease Term,
Landlord shall pay the Security Deposit to Landlord's successor in interest in
accordance with Civil Code Sec. 1950.7 or any successor statute, in which event
the transferring Landlord shall be released from all liability for the return of
the Security Deposit.

            4.8 Payment of Rent. All rent and Property Management Fees required
to be paid in monthly installments shall be paid in advance on the first (1st)
day of each calendar month during the Lease Term. All rent shall be paid in
lawful money of the United States, without any abatement, deduction or offset
whatsoever, except to the extent expressly permitted hereunder and without any
prior demand therefor. Tenant's failure to timely pay Additional Rent shall be
treated the same as the failure to timely pay Base Monthly Rent, and Landlord
shall have the same rights and remedies as Landlord would have for failure to
pay Base Monthly Rent when due. All rent shall be paid by check delivered to
Landlord at 105 South Drive, Suite 200, Mountain View, California 94040 or at
such other place as Landlord may designate from time to time. Tenant's
obligation to pay rent shall be prorated at the commencement and expiration of
the Lease Term.

            5.1 Common Area Use. Tenant and its employees, invitees and
customers may, together with other tenants in the Building, if any, make
reasonable use of any Common Area (if any). This right shall terminate upon the
termination of this Lease. Landlord reserves the right to, from time to time,
make changes to the shape, size, location, extent and amount of Common Area (if
any); provided that such changes shall not materially decrease Tenant's
available parking area or otherwise materially adversely affect Tenant's
occupancy. Tenant and its employees and customers shall comply with all
regulations reasonably promulgated by Landlord for use of the Common Area (if
any), and such regulations shall become a part of this Lease when received by
Tenant. The rules and regulations shall be binding upon Tenant upon delivery to

or without advance notice, and all amendments shall be effective upon delivery
to Tenant. Tenant shall have the exclusive use of one hundred percent (100%) of
the parking spaces on the Property. Tenant shall not abandon, and shall not

agrees that, notwithstanding the provisions contained in Section 2.4 or
elsewhere in this Lease, Tenant is required to remove such
improvements/alterations at the expiration or termination of this Lease and to
restore the Building to Landlord's complete satisfaction, as determined in
Landlord's sole discretion. In all events, Tenant shall, after removal of such
items at the end of the Lease Term, fully restore the applicable portions of the

                              REAL PROPERTY TAXES

            6.1 Real Property Taxes Defined. The term "Real Property Taxes", as
used in this Lease, shall mean: (i) all taxes, assessments, levies and other
charges of any kind or nature whatsoever, general and special, foreseen and
unforeseen (including all installments of principal and interest required to pay
any general or special assessments for public improvements and any increases
resulting from reassessments caused by any change in ownership) now or hereafter
imposed by any governmental or quasi-governmental authority or special district
having the direct or indirect power to tax or levy assessments, which are levied
or assessed against, or with respect to the value, occupancy or use of all, or
any portion of the Property (as now constructed or as may at any time hereafter
be constructed, altered or otherwise changed), or Landlord's interest therein;
the fixtures, equipment and other property of Landlord, real or personal, that
are an integral part of and located on the Property; the gross receipts, income
or rentals from the Property; or the use of parking areas, public utilities or
energy within the Property and (ii) all charges, levies or fees imposed by
reason of environmental regulation or other governmental control of the
Property. If any Real Property Tax is based upon property or rents unrelated to
the Property, then only that part of such Real Property Tax that is fairly
allocable to the Property shall be included within the meaning of the term "Real
Property Taxes". Notwithstanding the foregoing, the term "Real Property Taxes"
shall not include estate, inheritance, transfer, gift or franchise taxes of
Landlord, or the federal or state net income tax imposed on Landlord's income
from all sources.

            6.2 Payment of Real Property Taxes by Tenant.

                (a) Tenant shall pay, as Rent, the Tenant's Pro Rata Share of
Real Property Taxes.

                (b) Landlord may cause Tenant to pay Real Property Taxes in
accordance with any of the methods set forth in Section 4.4, or at Landlord's
election, as provided in this Section 6.2. During December of each calendar year
during the Lease Term, or as soon thereafter as practicable, Landlord may give
Tenant written notice of the amount of Real Property Taxes for the ensuing
calendar year. On or before the first day of each month during the ensuing
calendar year, Tenant shall pay to Landlord one-twelfth (1/12) of the estimated
amount; provided, that if notice is not given in December, Tenant shall continue
to pay on the basis of the then applicable Rent until the month after the notice
is given. If at any time it appears to Landlord that the increased amount
payable for the current calendar year will vary from Landlord's estimate by more
than five percent (5%), Landlord may give notice to Tenant of Landlord's revised
estimate for the year, and subsequent payments by Tenant for the year shall be
based on the revised estimate; provided, that Landlord shall not give notice of
a revised estimate for any year more frequently than once a calendar quarter.

                                       11
<PAGE>   12

                (c) Within one hundred twenty (120) days after the close of each
calendar year of the Lease Term, or as soon after the one hundred twenty (120)
day period as practicable, Landlord may deliver to Tenant a statement of the
adjustment to the Real Property Taxes for the prior calendar year; the statement
shall be final and binding upon Landlord and Tenant. If, on the basis of the
statement, Tenant owes an amount that is less than the estimated payments for
the calendar year previously made by Tenant, Landlord may apply the excess to
the next payment of increased Real Property Taxes due (or refund such excess to
Tenant within thirty (30) days if the Lease has terminated). If, on the basis of
the statement, Tenant owes an amount that is more than the estimated payments
for the calendar year previously made by Tenant, Tenant shall pay the deficiency
to Landlord within thirty (30) days after delivery of the statement.

                (d) Notwithstanding any other provision hereof, Tenant shall pay
the full amount of any Real Property Taxes during the Lease Term resulting from
any and all alterations and tenant improvements of any kind whatsoever placed
in, on or about the Property for the benefit of, at the request of, or by
Tenant. Tenant shall pay, prior to delinquency, all taxes assessed or levied
against Tenant's personal property in, on or about the Property. When possible,
Tenant shall cause its personal property to be assessed and billed separately
from the real or personal property of Landlord.

                (e) Upon request by Tenant, Landlord shall provide Tenant with a
copy of the most recent tax bill for the Property. Tenant shall have the right
to contest the validity or amount of any Real Property Taxes payable for the
Property by appropriate proceeding diligently conducted in good faith. Under no
circumstances shall Tenant join Landlord as a party to such proceedings. If
Tenant undertakes any such contest, Tenant may withhold or defer payment or pay
under protest; provided, that upon the request of the Landlord, prior to
delinquency of the Real Property Taxes in question Tenant shall obtain and
deliver to Landlord a good and sufficient surety bond or other assurance of
payment protecting Landlord and the Property from any lien, claim, demand, loss,
cost, liability or expense which Landlord or the Property might suffer or incur
as a consequence of the withheld or protested payment. Upon termination of any
contest, Tenant shall pay the amount finally determined to be payable, together
with all fines, interest, penalties or other charges incurred or payable as a
result thereof. Landlord shall not be subject to any liability for the payment
of any costs or expenses in connection with any such proceedings, and Tenant
will indemnify, protect, defend by counsel reasonably satisfactory to Landlord
and hold Landlord harmless from any such costs and expenses, reimbursing
Landlord therefor upon demand unless Landlord has initiated the proceedings.
Tenant shall be entitled to any refund of any Real Property Taxes and penalties
or interest from any governmental authority to the extent the refund represents
monies paid to the governmental authority by Tenant or paid by Landlord and
fully reimbursed by Tenant. In addition, Tenant shall be entitled to recover
from any Real Property Taxes the reasonable cost (but in no event greater than
the savings obtained) in obtaining such refund.

                6.3 Taxes on Tenant's Property. Tenant shall pay, before
delinquency, any and all taxes, assessments, license fees and public charges
levied, assessed or imposed against Tenant or Tenant's estate in this Lease, or
the property of Tenant situated within the Leased Premises, which become due
during the Lease Term. On demand by Landlord, Tenant shall furnish Landlord with
satisfactory evidence of these payments.

            7.1 Tenant's Insurance. Tenant shall maintain in full force and
effect during the Lease Term the following insurance:

                                       12
<PAGE>   13

                (a) A policy or policies of comprehensive general liability
insurance, including property damage, against liability for personal injury,
bodily injury, death and damage to property occurring in or about, or resulting
from an occurrence in or about the Leased Premises or resulting from Tenant's
use or occupancy of the Leased Premises, with combined single limit coverage of
not less than Three Million Dollars ($3,000,000).

                (b) A policy or policies of fire and property damage insurance
in so called "fire and extended coverage" form with a sprinkler leakage
endorsement (if the Building contains fire sprinklers) insuring its personal
property, inventory, trade fixtures and leasehold improvements within the Leased
Premises for the full replacement value thereof. The proceeds from any of such
policies shall be used for the repair or replacement of such items so insured;
provided that if the Lease shall terminate as a result of such insured loss, the
proceeds shall be the property of Tenant.

                (c) (intentionally omitted].

                (d) Workers' compensation and any other employee benefit
insurance sufficient to comply with all laws.

                (e) Landlord, and such others it designates, shall be named as
additional insured on the policies of insurance described in this Section 7.1
(a) and (b). All insurance required by this Section 7.1 shall: (i) as to the
liability insurance only, be primary insurance which provides that the insurer
shall be liable for the full amount of the loss, up to and including the total
amount of liability set forth in the declarations without the right of
contribution from any other insurance coverage of Landlord; (ii) provide that
such policies shall not be subject to cancellation or change, except after at
least thirty (30) days prior written notice to Landlord; and (iii) not have a
"deductible" in excess of Fifty Thousand Dollars ($50,000) on property insurance
and Twenty-Five Thousand Dollars ($25,000) on liability insurance per
occurrence. Each such policy shall also contain a waiver of any right of
subrogation against Landlord. Copies of such policy or policies, or duly
executed certificates for them, together with satisfactory evidence of the
payment of the premium thereon, shall be deposited with Landlord prior to the
time Tenant enters into possession of the Leased Premises, and upon renewal of
such policies, but not less than thirty (30) days prior to the expiration of the
term of such coverage.

                (f) Any insurance coverage required of Tenant in this Section
7.1 may be satisfied by a blanket policy or policies of insurance, provided that
the total amounts of insurance available with respect to the Property and
Tenant's liability under this Lease shall be at least the equivalent of separate
policies carried in the amounts required in this Lease.

            7.2 Landlord's Insurance.

                (a) Landlord shall maintain, as the minimum coverage required of
it by this Lease, a policy or policies of fire and property damage insurance, in
so-called "fire and extended coverage" form, insuring Landlord (and such others
as Landlord may designate) from physical damage to the Building including the
leasehold improvements made thereto at the commencement of the Lease Term, with
coverage of not less than one hundred percent (100%) of the full replacement
value thereof; provided, that such insurance may have a deductible in a
commercially reasonable amount. Landlord may so insure the Building separately,
or may insure the Building with other buildings and improvements within the
Property which Landlord elects to insure together under the same policy or
policies. Landlord shall not be required to cause such insurance to cover any
trade fixtures, leasehold improvements (except as provided above) or any
inventory or other personal property of Tenant.

                                       13
<PAGE>   14

                (b) Landlord shall maintain, as minimum coverage, comprehensive
general liability insurance, including property damage, against liability for
personal injury, bodily injury, death and damage occurring in or about, or
resulting from, an occurrence in or about the Leased Premises, with combined
single-limit coverage of not less than Three Million Dollars ($3,000,000).

            7.3 Release and Waiver of Subrogation: Notwithstanding anything to
the contrary in this Lease, the parties hereto release each other, and their
respective agents, employees and contractors, from any claims for injury to any
persons or damage to property that are caused by or result from risks insured
against under any insurance policies carried by the parties and in force at the
time of such damage, but only to the extent such claims are covered by such
insurance. This release shall be in effect only so long as the applicable
insurance policies contain a clause to the effect that this release shall not
affect the right of the insured to recover under such policies. Each party shall
cause each insurance policy obtained by it to provide that the insurance company
waives all rights of recovery by way of subrogation against either party in
connection with any damage covered by such policy, so long as such waiver is
available without unreasonable, additional cost. In the event any party is
unable to so obtain such waiver, such party shall notify the other, in writing,
and the other party may, if it so desires, obtain such waiver by payment of any
additional premium therefor.

            7.4 Limitation on Landlord's Liability and Indemnity. Except to the
extent of Landlord's active neglect or greater culpability, Landlord shall not
be liable to Tenant for, and Tenant hereby releases Landlord and its members,
managers, officers, employees, agents and representatives from any liability for
(a) any injury to or damage suffered by Tenant, Tenant's agents,
representatives, employees, contractors or invitees; (b) any damage to Tenant's
property or business due to any reason whatsoever, including, but not limited
to, the failure or destruction of any utilities such gas, electrical, water,
mechanical systems (e.g., HVAC), etc.; and (c) the failure to provide security
or the blockage of the Property. Tenant hereby waives the application of Civil
Code Section 1542, which provides that:

               "A general release does not extend to claims which the creditor
               does not know or suspect to exist in his favor at the time of
               executing the release, which, if known by him, must have
               materially affected his settlement with the debtor."

Commencing upon Tenant's entry on the Leased Premises, Tenant shall indemnify
Landlord and its officers, members, agents, representatives and employees, and
hold them harmless from all losses, claims, liabilities, costs, expenses
(including, but not limited to, attorneys' fees and costs) and damages
(collectively, "Losses" or, separately, a "Loss") arising out of the use,
occupancy or enjoyment of the Leased Premises by Tenant or any licensee,
invitee, employee, contractor, representative, or agent of Tenant, except that
which is caused by the active neglect or greater culpability of Landlord, or
arising out of Tenant's failure to perform any of its obligations under this
Lease. Tenant waives any right to recover from Landlord for any such Loss to any
person or property, including loss of income; it being Tenant's right and
obligation to insure against such Loss, by reason of the use, occupancy or
enjoyment of the Premises by Tenant, or any licensee, invitee, agent or employee
of Tenant. This indemnity shall survive the termination or expiration of this
Lease.

charge such costs to Tenant as Additional Rent.

                (e) Tenant waives all rights to make repairs at the expense of
the Landlord and to deduct the cost of such repairs from the Rent and
specifically waives all rights under Sections 1941 and 1942 of the California
Civil Code or any similar law regarding a Tenant's right to make repairs and
deduct the cost of such repairs from the Rent. (Without in any way limiting the
effect of the foregoing waiver, the parties acknowledge and agree that in the
case of an emergency, Tenant may make a repair that Landlord is otherwise
required to make and Landlord shall reimburse Tenant for the reasonable costs
thereof. In the absence of an "emergency", Tenant shall not be reimbursed. For
purposes of this Section 83(e), "emergency" shall mean (i) material damage to
the Leased Premises (not caused by Tenant) which results in an immediate threat
to life, serious bodily injury or material damage to a substantial portion of
Tenant's personal property or fixtures and (ii) Tenant has made repeated and
reasonable, but unsuccessful, attempts to notify Landlord. However, if Tenant
successfully notifies Landlord, then Landlord shall, in good faith, determine
whether an emergency exists. For purposes of an emergency under this Section
83(e), notice shall be deemed proper if notice is given by telephone and
promptly confirmed in writing by fax by an authorized officer.) There shall be
no allowance to Tenant for diminution of rental value, and no liability on the
part of Landlord by reason of inconvenience, annoyance or injury to business
arising from the making of or the failure to make, any repairs, alterations,
decorations, additions or improvements in or to any portion of the Leased
Premises or the Building or Common Area (or any of the areas used in connection
with the operation thereof, or in or to any fixtures, appurtenances or
equipment), or by reason of the negligence of Tenant or any other tenant or
occupant of the Property. In no event shall Landlord be responsible for any
consequential damages arising or alleged to have arisen from any of the
foregoing matters. Tenant hereby agrees that Landlord shall not be liable for
injury to Tenant's business or any loss of income therefrom or for damage to the
goods, wares, merchandise or other property of Tenant, Tenant's employees,
invitees, customers, or any other person in or about the Leased Premises, the
Building, or the Common Area, nor shall Landlord be liable for injury to the
person of Tenant, Tenant's employees, agents or contractors whether such damage
or injury is caused by or results from fire, steam, electricity, gas, water or
rain, or from the breakage, leakage, obstruction or other defects of pipes,
sprinklers, wires, appliances, plumbing, air conditioning or lighting fixtures,
or from any other cause, whether such damage or injury results from any other
cause, whether such damage or injury results from conditions arising upon the
Property or upon other portions of the Building, or from other sources or places
and regardless of whether the cause of such damage or injury or the means of
repairing the same is inaccessible to Tenant, except to the extent any of the
foregoing arises from the gross negligence of Landlord. Landlord shall not be
liable for any damages arising from any act or neglect of any other tenant, if
any, of the Building or the Property.

                (f) Tenant shall obtain and pay for all permits required for
Tenant's occupancy of the Property, other than permits relating to the physical
condition of the Property, and shall take all actions necessary to comply with
all applicable statutes, ordinances, rules, regulations, orders and requirements
regulating the use by Tenant of the Property, including any occupational safety
and health laws, provided that Tenant shall not be obligated to make any
physical changes in, or improvements to, the Property unless such changes or
improvements are required solely by reason of the unique nature of Tenant's use
of the Property (as opposed to standard office and research and development
usage).

                                       16

                (g) Tenant will cause all exposed plumbing, heating,
ventilating, air conditioning and electrical equipment within the Leased
Premises to be operated in accordance with the manufacturers' recommendations
and specifications.

                (h) At the end of the Lease Term or any extension period, Tenant
shall surrender to Landlord the Leased Premises broom clean, in the same
condition as they existed on the date of completion of the Tenant Improvements
described in Section 2.3, together with such changes as are permitted to remain
pursuant to this Lease, excepting only such ordinary wear and tear as could not
have been avoided by routine maintenance.

                (i) It is the intention of Landlord and Tenant that, at all
times during the Term, Tenant shall maintain the Property in an attractive first
class and fully operative condition. Tenant's repair obligation is unconditional
and does not depend on whether the repairs are necessitated by Tenant's use or
whether the means of repair or item needing repair is readily accessible to
Tenant. If Tenant fails to perform proper maintenance or repair, including
preventative maintenance where appropriate, Landlord may, after seven (7) days
written notice to Tenant (or without notice for emergency repairs), cause the
same to be performed, and the cost thereof will promptly be paid by Tenant upon
receipt of a statement from Landlord setting forth the amount due. Any such
amount shall be deemed additional rent.

        Landlord shall have no maintenance or repair obligations whatsoever with
respect to the Leased Premises except as expressly provided in Section 8.2.
Tenant shall, upon Landlord's request, provide Landlord with copies of all
maintenance and service reports and records, including, but not limited to,
electrical and HVAC reports.

            8.4 Hazardous Materials.

                (a) Except in accordance with the relevant statutes and
regulations, Tenant shall not cause or permit to be discharged from or about the
Property or the Building, any hazardous, toxic, or radioactive materials,
including, but not limited to, those materials (i) identified in Section 66680
or within the criteria set forth in Section 66693 et seq. of Title 22 of the
California Code of Regulations, Division 4, Chapter 30, (ii) defined as a
"hazardous waste" pursuant to Section 1004 of the Federal Resource Conservation
and Recovery Act, 42 U.S.C. Section 6901 et seq. (42 U.S.C. Section 6903), or
(iii) defined as a "hazardous substance" pursuant to Section 101 of the
Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C.
Section 9601 et seq. (42 U.S.C. Section 9601) as amended from time to time, or
petroleum distillates (collectively, "Hazardous Materials"). Tenant shall at its
sole expense comply with all applicable governmental rules, regulations, codes,
ordinances, statutes and other requirements respecting Hazardous Materials in
connection with Tenant's activities on or about the Property or the Building.
Tenant shall at its sole cost perform all clean-up and remedial actions which
may be required of Tenant by any governmental authority pertaining to any
storage, handling use, generation or discharge of Hazardous Materials by Tenant.

                (b) Tenant shall indemnify, defend and hold harmless Landlord
and its members, officers, employees, agents and representatives, from and
against all Losses relating to the illegal storage handling, use, generation or
discharge of Hazardous Materials by Tenant on or about the Property or the
Building. Tenant shall reimburse Landlord for (i) losses in or reductions to
rental income resulting from Tenant's storage, handling, use, generation or
discharge of Hazardous Materials; (ii) all costs of clean-up or other
alterations to the Property necessitated by Tenant's storage, handling, use,
generation or discharge of Hazardous Materials; and (iii) any diminution in the
fair market value of the Building caused by Tenant's use, storage, handling,
generation or discharge of Hazardous Materials. The obligations of Tenant under
this Section shall survive the expiration of the Lease Term.

                                       17
<PAGE>   18

                (c) Landlord shall indemnify, defend and hold harmless Tenant
and its officers, employees, agents and representatives, from and against all
Losses relating to the illegal storage, handling, use, generation or discharge
of Hazardous Materials on or about the Property or the Building, except as
provided in Section 8.4(b) above. Landlord shall reimburse Tenant for (i) losses
in or reductions to rental income resulting from such storage, handling, use,
generation or discharge of Hazardous Materials; (ii) all costs of clean-up or
other alterations to the Property necessitated by such storage, handling, use,
generation or discharge of Hazardous Materials; and (iii) any diminution in the
fair market value of the Building caused by such use, storage, handling,
generation or discharge of Hazardous Materials. The obligations of Landlord
under this Section shall survive the expiration of the Lease Term.

                                    SECTION 9
                    TRADE FIXTURES AND LEASEHOLD IMPROVEMENTS

            9.1 Trade Fixtures and Leasehold Improvements. Tenant shall not
construct any leasehold improvements or additions or otherwise alter the Leased
Premises without Landlord's prior written approval, which approval may be
withheld in Landlord's reasonable discretion; provided that Tenant may make
non-structural improvements of up to Twenty-Five Thousand Dollars ($25,000) to
the Leased Premises without Landlord's consent, if Tenant has provided Landlord
with (a) copies of all such plans and specifications and (b) a certificate of an
authorized officer of Tenant certifying that all permits, consents and required
approvals for such Improvements have been obtained and do not violate any laws
or this Lease. In no event shall Tenant make any alterations to the Leased
Premises which could affect the structural integrity or the design of the
Building without Landlord's prior consent. All such approved leasehold
Improvements shall be installed by Tenant at Tenant's expense using a licensed
contractor. All construction done by Tenant shall be done in accordance with all
laws (including valid building permits issued by the appropriate governmental
authority) and in a good and workmanlike manner, using new materials of good
quality. All leasehold Improvements shall remain the property of Tenant during
the Lease Term. At the termination of this Lease, the alterations, additions and
improvements made by Tenant shall remain on the Leased Premises and become the
property of Landlord, except that at Landlord's option, Specialized Improvements
and Reserved Improvements (as described in Section 2.4), shall be removed by
Tenant at Tenant's sole cost and expense, and Tenant shall restore the portions
of the Leased Premises affected by such Reserved Improvements and/or Specialized
Improvements to their prior condition. (Tenant and Landlord acknowledge and
agree that the items described in Sections 5.2 and 14.16 shall be removed and
the Leased Premises, Building and Property shall be restored to Landlord's
complete satisfaction, determined in Landlord's sole discretion.) Without
limiting the generality of the foregoing, all heating, lighting, electrical
(including all wiring, conduit, outlets, drops, buss, ducts, main and
subpanels), air conditioning, partitioning, drapery, and carpet installations
made by Tenant regardless of how affixed to the Leased Premises, together with
all other additions, alterations and improvements that have become an integral
part of the Building, shall be and become the property of the Landlord upon
termination of the Lease, and shall not be deemed trade fixtures, and shall
remain upon and be surrendered with the Leased Premises at the termination of
this Lease. If during the Lease Term, any alteration, addition or change to the
Common Area is required by law, regulation, ordinance or order of any public
agency, Landlord shall make the same and the costs of such alteration, addition
or change shall be a Common Area charge and Tenant shall pay its share of its
costs as provided in Section 4.3 above. Landlord may require Tenant to post a
payment and performance bond for one and one-half (1.5) times the estimated cost
of all work prior to commencement of any work by Tenant on the Leased Premises,
provided Tenant shall not be required to post such a bond if Tenant has a net
worth in excess of $11,000,000 or otherwise provides adequate assurance that
Tenant's share of any improvement costs will be timely paid.

                                       18
<PAGE>   19

            9.2 Landlord's Improvements. All fixtures, improvements or equipment
which are installed, constructed on or attached to the Property by Landlord, at
its expense, shall become a part of the realty and belong to Landlord.

            9.3 Liens. Tenant shall keep the Leased Premises and the Property
free from any liens and shall pay when due all bills arising out of any work
performed, materials furnished, or obligations incurred by Tenant, its agents,
employees or contractors relating to the Leased Premises. If any claim of lien
is recorded, Tenant shall bond against or discharge the same within ten (10)
days after the same has been recorded against the Leased Premises and/or the
Property. Tenant shall indemnify, defend, protect and hold Landlord and the
Property harmless and free from any liens, claims, liabilities, demands,
encumbrances, or judgments created or suffered by reason of any labor or
services performed for, materials used by or furnished to, Tenant or any
contractor employed by Tenant with respect to the Property. Tenant shall give
notice to Landlord in writing five (5) days prior to employing any laborer or
contractor to perform services related to, or receiving materials for use upon
the Property. Tenant shall permit Landlord to post a notice of
non-responsibility in accordance with the statutes or requirements of California
Civil Code Section 3094 or any amendment thereof.

            9.4 Signs. Tenant may, at Tenant's sole cost and expense, install
and maintain on the Property during the Lease Term a monument and building
facade sign with Tenant's name and logo, subject to compliance with the
requirements of the City of Mountain View and Landlord's consent, which consent
will not be unreasonably withheld. Tenant will not install any exterior signs
except in conformance with Landlord's reasonable rules and regulations. Signs
installed by Tenant not conforming to Landlord's rules and regulations may be
removed and/or replaced by Landlord at Tenant's cost.

                                   SECTION 10
                           DAMAGE TO LEASED PREMISES

            10.1 Landlord's Duty to Restore. If the Leased Premises and Building
are damaged by any peril after the Commencement Date of this Lease, Landlord
shall restore the same to a similar condition as existed prior to such damage,
unless the Lease is terminated by Landlord pursuant to Section 10.2, or by
Tenant, pursuant to Section 10.3. All insurance proceeds available from the fire
and property damage insurance carried by Landlord pursuant to Section 7.2, shall
be paid to and become the property of Landlord. If this Lease is not terminated,
then upon receipt of the insurance proceeds (if the loss is covered by
insurance) and the issuance of all necessary governmental permits, Landlord
shall commence and diligently proceed to complete the restoration of the Leased
Premises and/or Building, to the extent then allowed by law, to substantially
the same condition in which the Leased Premises and/or Building were immediately
prior to such damage. Landlord's obligation to restore shall be limited to the
Leased Premises and/or Building approved as they existed as of the Commencement
Date, leasehold improvements, trade fixtures and/or personal property
constructed or installed by Tenant in the Leased Premises; provided that
Landlord shall restore such leasehold improvements, trade fixtures and/or
personal property to the extent covered by the insurance policies described in
Section 7.2. Tenant shall forthwith replace or fully repair all leasehold
improvements and trade fixtures installed by Tenant and existing at the time of
such damage or destruction, to the extent not covered by Landlord as described
in the preceding sentence.

            10.2 Landlord's Right to Terminate. Landlord shall have the option
to terminate this Lease in the event any of the following occurs, which option
may be exercised only by

                                       19
<PAGE>   20

delivery to Tenant of a written notice of election to terminate within thirty
(30) days after the date of discovery of such damage:

                (a) The Building is damaged by any peril to such an extent that
the estimated cost to restore the Building exceeds the lesser of (i) the
insurance proceeds available from insurance actually carried by Landlord (unless
Tenant, at its option, agrees to pay the differential) or (ii) fifty percent
(50%) of the then replacement value thereof.

                (b) The Building is damaged by any peril both (i) not covered by
the type of insurance Landlord is required to carry pursuant to Section 7.2 and
(ii) not covered by valid and collectible insurance actually carried by Landlord
and in force at the time of such damage or destruction.

                (c) The Leased Premises are materially damaged by any peril
within six (6) months of the last day of the Lease Term. For purposes of this
Section 10.2(c), "material" means that the damage, based on Landlord's good
faith estimate, cannot be completely repaired within sixty (60) days after the
date such damage occurs.

                (d) The Building is damaged by any peril and, because of the
laws then in force, the Building: (i) may not be restored at reasonable cost to
substantially the same condition in which it was prior to such damage (unless
Tenant, at its option, agrees to pay the differential); or (ii) may not be used
for the same use being made thereof before such damage, whether or not restored
as required by this Section 10.2.

            10.3 Tenant's Right to Terminate. If the Leased Premises are damaged
by any peril, and Landlord does not elect to terminate this Lease, or is not
entitled to terminate this Lease pursuant to Section 10.2, then as soon as
reasonably practicable (using good faith efforts to expedite the matter),
Landlord shall furnish Tenant with the written opinion of Landlord's architect
or construction consultant as to when the restoration work required of Landlord
may be completed. Tenant shall have the option to terminate this Lease in the
event any of the following occurs, which option may be exercised only by
delivery to Landlord of a written notice of election to terminate within thirty
(30) days after Tenant receives from Landlord the estimate of the time needed to
complete such restoration:

                (a) The Leased Premises are damaged by any peril and, in the
reasonable opinion of Landlord's architect or construction consultant, the
restoration of the Leased Premises cannot be substantially completed within one
hundred eighty (180) days after the date of such damage.

                (b) The Leased Premises are materially damaged by any peril
within six (6) months of the last day of the Lease Term. For purposes of this
Section 10.3(b), "material" shall have the same meaning as set forth in Section
10.2(c) above.

            10.4 Abatement of Rent. In the event of damage to the Leased
Premises which does not result in the termination of this Lease, the Base
Monthly Rental and Additional Rent as then adjusted shall be temporarily abated
during the period of restoration in proportion to the degree to which Tenant's
use of the Leased Premises is impaired by such damage. Tenant shall not be
entitled to any compensation or damages from Landlord for loss of Tenant's
property or any inconvenience or annoyance caused by such damage or restoration;
provided that Landlord shall use commercially reasonable efforts to minimize the
disruption to the operation of Tenant's business in the Leased Premises.
Landlord and Tenant hereby waive the provisions of Section 1932, Subdivision 2,
and Section 1933, Subdivision 2, and Section 1933, Subdivision 4, of the
California Civil Code and the provisions of similar laws hereinafter enacted.

                                       20

                                   SECTION 11
                                 EMINENT DOMAIN

        If a public authority acquires all or any portion of the Premises
through eminent domain, or under threat thereof, and if Tenant's business may
not reasonably be continued on the portion of the Leased Premises not taken,
then this Lease shall terminate as of the date that the public authority becomes
entitled to possession of the property taken. In such event, Tenant shall be
entitled to receive such portion of the condemnation award as is designated by
the public authority as compensation for Tenant's trade fixtures, moving
expenses or loss of goodwill, and the balance of the condemnation award shall be
paid to Landlord.

                                   SECTION 12
                              DEFAULT AND REMEDIES

            12.1 Tenant's Default and Landlord's Remedies. The following
breaches by Tenant shall constitute material defaults entitling Landlord to the
remedies described in this Section:

                (i) abandonment of the Leased Premises;

                (ii) failure to pay rental or any other sum due Landlord within
five (5) business days after written notice by Landlord that such sum is past
due;

                (iii) a general assignment by Tenant for the benefit of
creditors or the commencement of any proceedings by or against Tenant under the
federal bankruptcy Code; or

                (iv) failure by Tenant to cure its breach of any other term,
condition or covenant of this Lease within a period of thirty (30) days after
the date of Landlord's written notice to Tenant of such breach is given;
provided if such default shall not be curable within such thirty (30) day
period, Tenant shall not be in default if Tenant shall have, within such thirty
(30)-day period, commenced cure of such default and shall thereafter pursue such
cure to completion. Upon any such default, Landlord may elect to terminate this
Lease and Tenant's right to possession of the Leased Premises, whereupon
Landlord may recover from Tenant: (a) the worth at the time of award of the
unpaid rent that had been earned at the time of termination; (b) the worth at
the time of award of the amount by which the unpaid rent, which would have been
earned after termination until the time of award, exceeds the amount of such
rental loss that Tenant proves could have reasonably been avoided; (c) the worth
at the time of award of the amount by which the unpaid rent for the balance of
the term after the time of award exceeds the amount of such rental loss that
Tenant proves could reasonably be avoided; computed by discounting such amount
at the discount rate of the Federal Reserve Bank of San Francisco at the time of
award, plus one percent (1%); or (d) any other amount necessary to compensate
Landlord for all the detriment proximately caused by Tenant's failure to perform
its obligations under the Lease, or which, in the ordinary course of things,
would be likely to result therefrom. If Landlord does not specifically elect, in
writing, to terminate Tenant's right to possession after Tenant has defaulted,
Landlord may enforce all its rights and remedies under the Lease, including the
right to recover the rent as it comes due.

            12.2 Landlord's Default and Tenant's Remedies. If Landlord fails to
perform its obligations under this Lease, Landlord shall nevertheless not be in
default under the terms of this Lease until such time as Tenant shall have first
given Landlord written notice specifying the nature of such failure to perform
its obligations, and then only after Landlord shall have had thirty (30) days
after its receipt of such notice within which to perform such obligations;
provided that, if

                                       21
<PAGE>   22

longer than thirty (30) days is reasonably required in order to perform such
obligations, Landlord shall have such longer period as is reasonably necessary
so long as Landlord makes a good faith effort to commence such cure within such
thirty (30) day period and diligently pursue the cure to completion thereafter.
In the event of Landlord's default as described above, then, and only then,
Tenant may then proceed in equity or at law to compel Landlord to perform its
obligations and/or to recover damages approximately caused by such failure to
perform (except as and to the extent Tenant has waived its right to damages as
provided in this Lease). Tenant's recourse shall be limited to Landlord's
interest in the property.

            12.3 Waiver. One party's consent to or approval of any act by the
other party requiring consent or approval shall not be deemed to waive or render
unnecessary the other party's consent to or approval of any subsequent similar
act. No delay or omission in the exercise of any right or remedy accruing to
either party upon any breach by the other party under this Lease shall impair
such right or remedy or be construed as a waiver of any such breach theretofore,
or hereafter occurring. The waiver by either party of any breach of any
provision of this Lease shall not be deemed to be a waiver of any subsequent
breach of the same or any other provisions herein contained.

            12.4 Holding Over. The Lease shall terminate and become null and
void without notice upon the expiration of the Lease Term. If Tenant holds over
for any period after the Lease Term, Landlord may, at its option, treat Tenant
as a tenant from month-to-month commencing on the first day after the Lease
Term, subject to the conditions in the Lease at a rental amount of one hundred
and fifty percent (150%) of the last Base Monthly Rental, plus all other charges
(if any). If Tenant fails to surrender the Property, Tenant shall indemnify,
defend and hold harmless Landlord from and against any and all losses, claims
and liabilities resulting therefrom or thereafter.

                                   SECTION 13
                    ASSIGNMENT AND SUBLETTING, SUBORDINATION

            13.1 Assignment and Subletting. Tenant shall not perform any of the
following acts without Landlord's prior written consent, which consent shall not
be unreasonably withheld: (a) assign or sublet all or any portion of Tenant's
interest in this Lease or in the Leased Premises; (b) pledge, mortgage or
hypothecate its interest in the Leased Premises; and (c) perform or suffer any
other act whereby any right of Tenant under this Lease is transferred (which act
shall be deemed to be an assignment for the purposes of this Section 13.1).
Notwithstanding the foregoing, Tenant may, without Landlord's consent, assign
this Lease or sublet all or any portion of the Premises to an Affiliate of
Tenant if Tenant guarantees the obligations of such Affiliate's performance of
this Lease (in a form of guaranty reasonably acceptable to Landlord and Tenant)
or remains primarily liable under this Lease, at Landlord's option. A change in
control of Tenant shall be deemed an assignment subject to Landlord's consent.
For purposes of this Lease, "change in control" shall mean the sale or transfer
of substantially all of Tenants assets to an entity which has a net worth less
than the net worth of Tenant as of the Commencement Date; provided that Tenant
shall have the burden of establishing the net worth of the proposed assignee.
"Affiliate" means any entity directly or indirectly controlled by Tenant with
the power to direct the policies and management of such entity (including, but
not limited to, subsidiaries) or the surviving entity after the merger of Tenant
with or into another entity. Landlord's consent to any one assignment,
subletting, or other transfer shall not constitute consent to any subsequent
transfer. Any attempted subletting or assignment without Landlord's prior
written consent, at Landlord's election, shall constitute a default by Tenant
under the terms of this Lease. The acceptance of rent by Landlord from any
person or entity other than Tenant, or the acceptance of rent by Landlord from
Tenant with knowledge of a violation of this Section 13.1, shall not be deemed
to be a waiver by Landlord

                                       22
<PAGE>   23

of any provision of this Section 13.1 of this Lease or to be a consent to any
such subletting or assignment by Tenant. Without limiting the circumstances in
which it may be reasonable for Landlord to withhold its consent to an assignment
or subletting, Landlord and Tenant acknowledge that it shall be reasonable for
Landlord to withhold its consent in the following instances:

                (a) the proposed assignee or sublessee is a governmental agency;

                (b) in Landlord's reasonable judgment, the use of the Leased
Premises by the proposed assignee or sublessee will involve occupancy by other
than primarily general office personnel, would entail any alterations which
would lessen the value of the leasehold improvements in the Leased Premises, or
would require increased services by Landlord;

                (c) in Landlord's reasonable judgment, the proposed assignee
does not meet the credit standards supplied by Landlord;

                (d) the proposed assignee (or any other of its Affiliates) has
been in material default under a lease, has been in litigation with a previous
landlord, or in the ten (10) years prior to the assignment, has filed for
bankruptcy protection or has otherwise been involved in an insolvency
proceeding;

                (e) Landlord has experienced a previous default by or is in
litigation with the proposed assignee or sublessee;

                (f) in Landlord's reasonable judgment, the Leased Premises will
be used in a manner that will violate any negative covenant as to use contained
in this Lease;

                (g) the use of the Leased Premises will violate any applicable
law;

                (h) the proposed assignment or sublease fails to include all of
the terms and provisions reasonably required to be included by the Landlord;

                (i) Tenant is then in default of any obligation under this Lease
beyond the applicable notice and cure period, or Tenant has defaulted under this
Lease on three (3) or more occasions beyond the applicable notice and cure
period during the twelve (12) months preceding the date that Tenant requests
such consent; or

                (j) in the case of a subletting of less than the entire Leased
Premises, if the subletting will require improvements to be made which are
unacceptable to Landlord, in Landlord's reasonable discretion.

            13.2 Additional Rent. If Tenant assigns this Lease or subleases the
Premises, Tenant shall, in consideration therefor, pay to Landlord, as
additional rent:

                (a) In the case of an assignment (excluding an assignment to an
Affiliate), an amount equal to fifty percent (50%0) of all sums and other
consideration paid to Tenant by the assignee for, or by reason of, such
assignment (including, without limiting the generality of the foregoing, all
sums paid for the sale of Tenant's fixtures or leasehold improvements, less the
then net unamortized or undepreciated cost thereof determined on the basis of
Tenant's Federal income tax returns) less the costs actually incurred by Tenant
for commissions (at fair market rates) and reasonable attorneys' fees; and

                (b) In the case of a sublease (excluding subleases to
Affiliates), fifty percent (50%) of any rents, additional charges, or other
consideration payable under the sublease by the subtenant to Tenant that are in
excess of the rent and expenses accruing during the term of

                                       23
<PAGE>   24

the sublease in respect of the subleased space (at the rate per square foot
payable by Tenant under this lease) pursuant to the terms hereof (including,
without limiting the generality of the foregoing, all sums paid for the sale or
rental of Tenant's fixtures or leasehold improvements, less, in the case of the
sale thereof, the then net unamortized or undepreciated cost thereof determined
on the basis of Tenant's federal income tax returns) less the costs actually
incurred by Tenant for commissions (at fair market rates) and reasonable
attorneys' fees, all such costs to be amortized without interest over the length
of the sublease term.

                The sums payable under Section 13.2(a) above shall be paid to
Landlord as and when received by Tenant. The sums payable under Section 13.2(b)
above shall be paid to Landlord as and when paid by the sublessee to Tenant.
Within thirty (30) days after written request therefor by Landlord, Tenant shall
at any time and from time to time furnish evidence to Landlord of the amount of
all such sums or other consideration received or expected to be received.

            13.3 Assignment By Landlord. Landlord and its successors in interest
shall have the right to transfer their interest in the Leased Premises and the
Property at any time and to any person or entity. In the event of any such
transfer, but only in the event the transferee, in writing, delivered to Tenant,
shall have assumed all liability of Landlord hereunder, the Landlord originally
named herein (and in the case of any subsequent transfer, the transferor) from
the date of such transfer, shall be automatically relieved, without any further
act by any person or entity, of all liability for the performance of the
obligations of Landlord hereunder which may accrue after the date of such
transfer.

            13.4 Subordination. This Lease is subject and subordinate to all
mortgages and deeds of trust which affect the Property and are of public record
as of the date of this Lease, and to all renewals, modifications,
consolidations, replacements and extensions thereof. However, if any lender
holding such mortgage or deed of trust shall advise Landlord that it desires or
requires this Lease to be prior and superior thereto, then, upon written request
of Landlord to Tenant, Tenant shall promptly execute, acknowledge and deliver
any and all documents or instruments which Landlord or such Lender reasonably
deems necessary to make this Lease prior thereto (provided no such document
shall alter, amend or modify any provision of this Lease). At Landlord's
election, this Lease shall become and thereafter remain subject and subordinate
to any and all future mortgages or deeds of trust affecting the Property which
may hereafter be executed and placed on public record after the effective date
of this Lease, or any renewals, modifications, consolidations, replacements or
extensions thereof, for the full amount of all advances made or to be made
thereunder and without regard to the time or character of such advances, so long
as the Lender holding the mortgage or deed of trust to which this Lease is to be
subordinated agrees in writing that it will recognize Tenant's rights under this
Lease and not disturb its quiet possession of the Leased Premises so long as
Tenant is not in default hereunder. Tenant will, within fifteen (15) days after
Landlord's written request therefor, execute, acknowledge and deliver upon
request of Landlord any and all documents or instruments as described above.
Landlord shall use its best efforts to provide Tenant current lender information
and a nondisturbance and attornment agreement.

            13.5 Landlord's Recapture Right. Despite any other provision of this
Section 13, Landlord has the option, by written notice to Tenant (the "Recapture
Notice") within thirty (30) days after receiving notice of Tenant's desire to
sublet fifty percent (50%) or more of the Premises for a term in excess of three
(3) years, to recapture the Premises by terminating this Lease or taking an
assignment or sublease of the Premises from Tenant. A timely Recapture Notice
terminates this Lease or creates an assignment or a sublease for the Premises
for the same term as proposed by Tenant, effective as of the date specified in
Tenant's notice. If Landlord declines or fails to timely deliver a Recapture
Notice, Landlord shall have no further right under this Section 13.5 unless and
until Tenant's subsequent attempt to sublet such Premises. Notwithstanding
anything to the contrary in this Lease, this Section 13.5 shall not apply to a
transfer to an Affiliate.

                                   SECTION 14
                               GENERAL PROVISIONS

            14.1 Landlord's Right to Enter. Landlord and its agents may enter
the Leased Premises at any reasonable time, but only upon twenty-four (24) hours
prior notice delivered during regular business hours, for the purpose of: (a)
inspecting the same; (b) posting notices of non-responsibility; (c) supplying
any service to be provided by Landlord to Tenant; (d) showing the Leased
Premises to prospective purchasers, mortgagees or, during the last nine (9)
months of the Lease Term, tenants; (e) making necessary alterations, additions
or repairs; (f) performing Tenant's obligation when Tenant has failed to do so
after written notice from Landlord; and for (g) placing upon the Leased Premises
ordinary "for lease" or "for sale" signs during the last nine (9) months of the
Lease Term. In case of an emergency, Landlord may enter the Leased Premises
without prior written notice, but shall notify Tenant as soon as possible and
shall take reasonable precautions to protect the security of Tenant's Premises.

            14.2 Surrender of the Leased Premises. Immediately prior to the
expiration, or upon the sooner termination of this Lease, Tenant shall vacate
and surrender the Leased Premises to Landlord in the condition required pursuant
to Section 2.4 above.

            14.3 Estoppel Certificates. At all times during the Lease Term,
Tenant will, following any request by Landlord, promptly execute and deliver to
Landlord an Estoppel Certificate: (a) certifying that this Lease is unmodified
and in full force and effect, or, if modified, stating the nature of such
modification and certifying that this Lease, as so modified, is in full force
and effect; (b) stating the date to which the rent and other charges are paid in
advance, if any; (c) acknowledging that there are not, to Tenant's knowledge,
any uncured defaults on the part of Landlord hereunder, or if there are uncured
defaults on the part of Landlord, stating the nature of such uncured defaults;
(d) the amount of Base Monthly Rent then in effect; and (e) certifying such
other information about the Lease as may be reasonably required by Landlord.
Tenant's failure to deliver an Estoppel Certificate within fifteen (15) days
after delivery of Landlord's request therefore shall be a conclusive admission
by Tenant that, as of the date of the request for such statement: (i) this Lease
is unmodified, except as may be represented by Landlord in such request and is
in full force and effect; (ii) there are no uncured defaults in Landlord's
performance; and (iii) no rent has been paid in advance.

            14.4 Notices. Any notice required or desired to be given regarding
this Lease shall be in writing and shall be personally served, or in lieu of
personal service, may be given by nationally recognized overnight courier
service or by certified mail addressed to the other party at the following

        If served by mail, such notice shall be deemed to have been given: (i)
on the third (3rd) business day after mailing if such notice was deposited in
the United States mail, certified and postage prepaid, addressed to the party to
be served at its address first above set forth; and (ii) in all other cases when
actually received. Either party may change its address by giving notice of same
in accordance with this Section 14.4.

            14.5 Attorneys' Fees. In the event either party brings any action or
legal proceeding (including arbitration) for an alleged breach of any provision
of this Lease, to recover rent, to terminate this Lease or to otherwise enforce,
protect or establish any term or covenant of this Lease, or right of either
party, the prevailing party shall be entitled to recover as a part of such
action or proceedings, or in a separate action brought for that purpose,
reasonable attorneys' fees and court costs as may be fixed by the court or
arbitration. The prevailing party shall be determined by the court or
arbitrator, as the case may be.

            14.6 Prevention of Performance. If either party to this Lease is
prevented in any way from performing its responsibilities under the Lease
because of intervening circumstances substantively beyond its control -- such as
labor relations actions, failures of transmission of supplies or utilities,
physical governmental or military preemptions, civil disturbances, or the like
-- such performance will be excused for the period during which the interruption
takes place, but must be resumed immediately after the end of the intervening
period. To the extent that such interruption does not physically prevent the
payment of any sums falling due and owing during such period, making of such
payments will not be excused. If any governmental body or agency imposes
structural improvement or other requirements which substantially increase the
cost of maintaining the Building in compliance with applicable laws and
regulations, Landlord may terminate this Lease upon sixty (60) days notice to
Tenant, unless Tenant, at its option, elects to pay that portion of the cost
which is in excess of what Landlord would be willing to pay.

            14.7 Tenant's Remedy. If, as a consequence of a default by Landlord
under this Lease, Tenant recovers a money judgment against Landlord, such
judgment shall be satisfied only out of the proceeds of sale received upon
execution of such judgment and levied thereon against the right, title and
interest of Landlord in the Building and out of Rent or other income from the
Building received by Landlord or out of consideration received by Landlord from
the sale of other disposition of all or any part of Landlord's right, title or
interest in the Building, and neither Landlord nor its members, partners,
owners, representatives or agents shall be liable for any deficiency.

            14.8 Mortgagee Protection. If Landlord defaults under this Lease,
Tenant will notify by registered or certified mail to any beneficiary of a deed
or trust or mortgagee covering the Building or the Property, of whom Tenant has
been notified in writing, and offer such beneficiary or mortgagee a reasonable
opportunity to cure the default, including time to obtain possession of the
Building by power of sale or a judicial foreclosure, or control of the Building
via appointment of a receiver if such should prove necessary to effect a cure.

            14.9 Acceptance. Delivery of this Lease, duly executed by Tenant,
constitutes an offer to lease the Leased Premises, and under no circumstances
shall such delivery be deemed to create an option or reservation to lease the
Leased Premises for the benefit of Tenant. This Lease shall only become
effective and binding upon full execution hereof by Landlord and delivery of a
signed copy to Tenant.

            14.10 Recording. Neither party shall record this Lease.

            14.11 Rules of Construction.

                (a) Time is of the essence.

                (b) The liability of multiple tenants or multiple landlords
shall be joint and several.

                (c) The rent payable under this Lease has been determined in
light of all other provisions hereof. The parties have had an equal opportunity
to review and comment upon the terms and provisions of this Lease; accordingly,
neither party shall be deemed the draftsman of this Lease, and there shall be no
presumption that it is to be interpreted for or against either party. Section
headings do not define or limit the operative provisions hereof.

                (d) This Lease, and its Exhibits, constitute the entire
agreement between the parties and there have been no promises or understandings
concerning the Leased Premises or the subject matter of this Lease that are not
set forth herein.

                (e) Acceptance by either party of late performance by the other
shall not constitute a waiver of the right to demand timely performance in the
future and Landlord's acceptance of rent does not waive any default by Tenant,
other than a prior default in the payment of such rent.

                (f) Each of the parties executing this Lease has authority to
execute this Lease.

                (g) This Lease shall be governed by the laws of the State of
California.

            14.12 Addendum. If an Addendum containing additional provisions is
attached to this Lease it is incorporated herein and the provisions thereof
supersede the provisions of this Lease to the extent they are inconsistent
therewith.

            14.13 Brokerage Commissions. Except for Tory Corporate Real Estate
Advisors dba The Staubach Company, Tenant warrants that it has not had any
dealing with any real estate brokers, leasing agents, or salespersons, or
incurred any obligations for the payment of real estate brokerage commissions or
finder's fees which would be earned or due and payable by reason of the
execution of this Lease. Pursuant to the terms and conditions of that certain
agreement between Cornish & Carey Commercial and Landlord, Landlord shall pay
only the commissions specified in such agreement. Tenant shall indemnify and
hold harmless Landlord from any claims for fees or commissions not covered by
such agreement.

            14.14 Financial Statements. Tenant will provide Landlord, within
thirty (30) days after written request from Landlord, if Landlord reasonably
requires such statements for purposes of sale or refinancing of the Property
or similar purposes, but no more often than twice per year, Tenant's most recent
audited 10-K statement and Tenant's most recent unaudited 10-Q statement (which
latter statement will be accompanied by a certificate from Tenant's chief
financial officer certifying that there has been no material change in Tenant's
financials since the date of issuance of

                                       27
<PAGE>   28

the 10-Q. Landlord may disclose such information to its lender or any investor,
prospective purchaser or investor, or any other person with an actual need to
know. Any such financial information which is marked "confidential" will be
confidential and shall not be disclosed to any third party except as set forth
in this Section 14.14.

            14.15 Indemnification. Each party and its successors and assigns,
shall indemnify, defend and hold harmless the other party, its members,
officers, employees, agents, representative, successors and assigns
(collectively, "Indemnified Persons") from and against any and all losses
(excluding special or consequential losses) which any one of the Indemnified
Persons may sustain or incur as a result of, in connection with or arising out
of the first party's breach of any covenant, obligation or representation of
such party in this Lease.

            14.16 Backup Generator. Tenant, at its sole cost, shall have the
right to install, at a mutually acceptable location on the Property, a backup
generator; provided that Tenant complies with all applicable laws.
Notwithstanding anything to the contrary in Section 2.4 or any other provision
of this Agreement, Tenant hereby acknowledges and agrees that Tenant shall
remove the backup generator upon the termination or expiration of the Lease
Term, and shall restore the Property to the complete satisfaction of Landlord,
determined in Landlord's sole discretion. Landlord shall be reasonable in
participating in the determination of a mutually acceptable location.

        IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease as of
the date set forth on Page 1 of this Lease.

                             OFFICE LEASE AGREEMENT

        THIS OFFICE LEASE AGREEMENT (this "LEASE"), dated to be effective as of
this 22nd day of February, 2000, is made by and between KCD-TX I INVESTMENT
LIMITED PARTNERSHIP, a Texas limited partnership ("LANDLORD OR KCD"), and
LACERTE SOFTWARE CORPORATION, a Delaware corporation ("TENANT" or "LACERTE").

                              PRELIMINARY RECITALS

        A. Electronic Data Systems Corporation ("EDS") is the owner of (i) a
certain tract of unimproved real property containing approximately 10.7 acres
located in the Legacy Park development in the City of Plano, Texas, which real
property is generally described on Exhibit "A," attached hereto and made a part
hereof, and which shall be used for Phase I of the Project (the "PHASE I
PROPERTY"); and (ii) a tract containing approximately 8.8 acres of land which
may be used for additional phases and/or expansions of the Project (the "FUTURE
DEVELOPMENT PROPERTY") which is generally described on Exhibit "A-1" attached
hereto (the Phase I Property and the Future Development Property are hereinafter
collectively referred to as the "REAL PROPERTY").

        B. Landlord warrants that it shall acquire those portions of the Real
Property from EDS as necessary to satisfy the requirement to develop the Project
and any Project Expansion as contemplated herein, in accordance with the terms
of that certain Contract for the Purchase and Sale of Real Estate to be executed
by Landlord and EDS (the "ACQUISITION CONTRACT"), and when so executed, a copy
of which shall be attached hereto as Exhibit "A-2" in accordance with Section
1.01(b). Landlord also warrants that, so long as Lacerte has not committed an
uncured Event of Default, Landlord will not amend the provisions of the
Acquisition Contract without Lacerte's consent, which shall not be unreasonably
withheld.

        C. When Landlord acquires the Phase I Property, it shall construct on
the Phase I Property an office building containing approximately 165,000 square
feet of gross building area (the "BUILDING") as well as a minimum of seven
hundred fifty (750) parking spaces, or such greater amount as may be necessary
to satisfy applicable ordinances with respect to the parking required for the
Building (the "PARKING") (the Building and Parking are collectively sometimes
referred to herein as "PHASE I"). The Building, Parking and the Phase I
Property, if and when constructed, are collectively hereinafter referred to as
the "PROJECT"). The development of the Future Development Property shall be
controlled by the provisions of Article 25 hereof, and upon the acquisition of
any portion of the Future Development Property, such property shall become part
of the Project for purposes of this Lease.

        D. Tenant desires to lease the Project on the terms and conditions
hereinafter provided.

<PAGE>   9

        E. To induce Landlord to execute this Lease, Tenant has caused, and
Intuit Inc. (the "GUARANTOR" or "INTUIT") has agreed to execute, that certain
guaranty agreement (the "INTUIT GUARANTY") attached hereto as Exhibit "D-1." For
purposes of this Lease, the term "Guarantor" shall include any "Substitute
Guarantor" as provided in the Intuit Guaranty, unless expressly stated to the
contrary herein.

        NOW, THEREFORE, for and consideration of the rent herein after reserved
and the mutual covenants hereinafter contained, Landlord and Tenant agree as
follows:

                                ARTICLE 1 - LEASE

        SECTION 1.01 PROPERTY.

        (a) Subject to Landlord's acquisition of the Phase I Property and
completion of the Project in accordance with the terms of this Lease, Landlord
hereby leases and demises the Project to Tenant and Tenant hereby hires, leases
and accepts the Project from Landlord, for the Term (as defined in Section 4.01)
and subject to the agreements, conditions and provisions contained herein.

        (b) Title to the Real Property shall be burdened by certain title
exceptions which exist as of the date hereof and which are required to be
established by the Landlord in connection with the Acquisition Contract and the
development of the Project. Upon receipt thereof by Landlord, Landlord shall
deliver to Tenant (i) a commitment for title insurance covering the Real
Property and legible copies of all exception documents shown therein for
Tenant's review and approval, (ii) an on the ground boundary survey of the Real
Property showing the location of any easements and other encumbrances to title,
and (iii) the final form of Acquisition Contract to be executed-by Landlord and
EDS. Tenant will receive an opportunity to review and approve the Supplemental
Declaration referred to in Section 14.04(b) of the Acquisition Contract, the
Option Supplemental Declaration referred to in Section 14.05, as well as any
other restrictions or instruments that will be recorded pursuant to the terms of
the Acquisition Contract, including the terms and provisions of the Special
Warranty Deed. Within ten (10) business days following receipt by Tenant of all
of the foregoing materials, Tenant shall either approve the Acquisition
Contract, the exceptions to title shown in such title commitment, the additional
title documents referenced above, and the survey (the "PERMITTED EXCEPTIONS"),
or Tenant shall deliver written notice to Landlord terminating this Lease. If
Tenant fails to deliver such notice, Tenant shall be deemed to have waived any
objection to title to the Real Property and shall have accepted the Acquisition
Contract and Permitted Exceptions. Upon approval of the Permitted Exceptions,
Landlord and Tenant agree that same shall be described on Exhibit "I" to the
Lease which shall be incorporated herein by reference for all purposes. Upon
approval of the Acquisition Contract, a fully executed copy of same shall be
attached to this Lease as Exhibit "A-2" which shall be incorporated herein by
reference for all purposes. Landlord covenants that it shall not permit any
additional easements and exceptions other than the Permitted Exceptions to title
to be recorded against title to the Real Property except those easements and
exceptions which are necessary in connection with the development of the
Project, and in any event such additional exceptions and easements shall not
impair Tenant's use of the Project. As soon as possible after the

                                       2
<PAGE>   10

Substantial completion of construction of the shell of the Building, Landlord's
architect, HKS, Inc. ("ARCHITECT"), shall compute the Rentable Area (hereafter
defined) contained in the Building. For purposes of calculating rentals due
hereunder, the good faith calculations of Architect made in accordance with
Section 1.02 hereof shall, subject to the review and approval thereof by Tenant
and Landlord, determine the Rentable Area contained in the Building. If Tenant
and Landlord are unable to agree on the Rentable Area contained in the Building,
the President of the Dallas Chapter of the AIA shall be appointed (and
compensated equally by Landlord and Tenant, unless the Architect's determination
of the total square feet of area contained in the Building exceeds the amount of
total square feet of area contained in the Building as determined by the
President of the Dallas Chapter of the AIA by more than 5%, in which case such
compensation shall be paid by Landlord) as the final arbiter of the Rentable
Area in the Building.

        SECTION 1.02 RENTABLE AREA. The measurement for the total square feet of
gross building area contained in the Building (which shall, for purposes of this
Lease, be referred to as "RENTABLE AREA") shall be made in accordance with the
method of measuring gross building area of office space in a single tenant
occupied building as specified in the Standard Method for Measuring Floor Area
in Office Buildings published by the Building Owners and Managers Association
International in ANSI Z 65.1-1996, revised and readopted June 7, 1996.

                    ARTICLE 2 - CONSTRUCTION OF THE BUILDING

        SECTION 2.01 DEVELOPMENT SCHEDULE. Attached hereto as Exhibit "B" and
incorporated herein by reference is a development schedule (the "DEVELOPMENT
SCHEDULE") detailing the Project's construction process, responsibilities of
Landlord and Tenant and the time periods within which each party's obligations
are to be performed. Both parties acknowledge that strict adherence to the
Development Schedule is essential for an orderly and timely completion of
construction of the Project, including the Base Building Work (as hereinafter
defined) and all Tenant Improvements (as hereinafter defined); provided,
however, each construction period obligation which is to be performed shall be
extended in the event of a delay in a prior date [whether caused by Landlord,
Tenant, a third party, or Force Majeure (as hereinafter defined)] by the number
of days of such delay. Phase I of the Project shall consist of the construction
and occupancy of approximately 165,000 square feet of Rentable Area and shall
contain a minimum of seven hundred fifty (750) parking spaces or such greater
amount as may be required to satisfy Laws based upon a building which contains
165,000 square feet, as shown on the site plan attached hereto as Exhibit "C-1"
(the "SITE PLAN"). Landlord and Tenant agree that construction of the Project
may occur in multiple phases and such future phases and/or expansions of the
Project (each, a "PROJECT EXPANSION") may consist of the construction and
occupancy of an additional amount of square feet of Rentable Area as described
in Article 25 of this Lease. Any Project Expansion shall be constructed and
occupied, and Base Rent shall commence to accrue thereon, all in accordance with
the provisions of Article 25.

        Section 2.02 BASE BUILDING WORK. Landlord and Tenant agree that the
construction specifications attached hereto as Exhibit "C" (the "BASE BUILDING
OUTLINE SPECIFICATIONS") constitute the outline specifications for the
Landlord's work in the development of the Project. The

                                       3
<PAGE>   11

Base Building Outline Specifications shall be deemed to include such additional
detail as may be necessary to satisfy the intent of the parties that such
specifications are sufficient, as drafted, to permit the Architect to prepare
the Base Building Final Plans and Specifications (as hereinafter defined)
without the addition of substantive design elements not described therein
(hereinafter referred to as "Additional Detail"). The Base Building Outline
Specifications incorporate the Site Plan for the Project which is attached
hereto as Exhibit "C-l," which Site Plan is hereby approved by Landlord and
Tenant. Landlord and Tenant acknowledge that the Site Plan is merely
illustrative of the conceptual layout of the Project and is not intended to
provide the scope or detail which is shown in the Base Building Outline
Specifications. Landlord shall provide all utilities and off-site improvements
for the construction of the Building, and shall construct or cause the Project
to be constructed: (i) substantially in accordance with the Base Building Final
Plans and Specifications; (ii) in a good and workmanlike manner; and (iii) in a
timely manner in accordance with the Development Schedule (subject to Force
Majeure, as described in Section 2.15, and Tenant Delays, as described in
Section 2.16) at no cost to Tenant, except for costs related to Tenant Changes
as described in Section 2.14 and Tenant Delays. The scope of the physical
improvements which constitute the Project excluding the Tenant Improvements
shall be limited to the improvements described in the Base Building Outline
Specifications. Landlord's undertakings described in this Section 2.02 shall be
referred to collectively as the "BASE BUILDING WORK." Landlord shall solicit one
(1) or more bids from, or may negotiate directly with one or more, general
contractors unaffiliated with Landlord or Tenant and shall contract with (with
Tenant's approval, which approval shall not be unreasonably withheld,
conditioned or delayed) a general contractor to construct the Base Building Work
(the "CONTRACTOR"), shall cause the Base Building Work to be constructed, and
shall cause the Project to be constructed in accordance with Laws (as defined in
Section 8.01) and Covenants (as defined in Section 13.02). The Tenant may, at
its election, cause the Contractor to solicit bids from subcontractors to
provide any of the work for the Project as required by the Tenant. Any cost
increases attributable to any contractor selected by the Tenant, shall be
considered a Tenant Change pursuant to Section 2.14. Any delay attributable to
materials or finishes not timely installed or delivered by any contractor
selected by the Tenant which is providing services directly to the Tenant or the
Contractor shall be considered a Tenant Delay for purposes of this Lease. All
preliminary plans and specifications for construction of the Base Building Work
shall be prepared by Architect at Landlord's sole cost and expense in accordance
with the budget established for the Project by the Landlord, shall be based upon
the Base Building Outline Specifications and shall be completed in accordance
with the terms of the Development Schedule. Preliminary and final drafts of the
final plans shall be promptly submitted by Landlord to Tenant. If within fifteen
(15) days after receipt by Tenant of any plans and specifications for the
Project, Tenant informs Landlord, in writing, that such plans and specifications
are not substantially in conformance with the Base Building Outline
Specifications and how such plans and specifications deviate from the Base
Building Outline Specifications, then Landlord shall promptly cause the plans
and specifications to be modified so as to conform to the Base Building Outline
Specifications. If Tenant has not so notified Landlord within fifteen (15) days
after receipt by Tenant of any plans and specifications for the Project, such
plans and specifications shall be deemed to be approved. Once the plans and
specifications have been approved by Tenant, or deemed to have been approved by
Tenant due to its non-response to any submission for approval, such set shall
then become the final plans and

                                       4
<PAGE>   12

specifications ("BASE BUILDING FINAL PLANS AND SPECIFICATIONS"). It is agreed
that the Base Building Final Plans and Specifications shall be deemed to include
the Additional Detail, whether or not specifically identified therein, as such
Base Building Outline Specifications may have been modified with Tenant's
consent. It is expressly understood and agreed by Landlord and Tenant that the
Base Building Final Plans and Specifications shall, when approved, supersede the
Base Building Outline Specifications for purposes of the completion of the Base
Building Work.

        Section 2.03 TENANT IMPROVEMENTS. Prior to the date specified in the
Development Schedule for preparation of the Tenant Improvements design work, as
such date may be extended in accordance with the terms of this Lease, Landlord,
Tenant's representative and the architect retained by Tenant to design the
Tenant Improvements, who may also be the Architect at Tenant's election (such
architect providing design services in connection with the Tenant Improvements
shall be referred to herein as the "TI ARCHITECT") shall meet to discuss the
design and construction of those improvements to the Building desired by Tenant
other than the Base Building Work (the "TENANT IMPROVEMENTS"). All improvements
not part of the Base Building Work shall be considered Tenant Improvements.
Tenant shall contract directly with the TI Architect to provide architectural
services in connection with the design and installation of the Tenant
Improvements. Such agreement with the TI Architect for the Tenant Improvements
shall be in a form reasonably acceptable to the Landlord and shall name
Landlord's representative as a party to whom all correspondence shall be copied
under the terms of the such agreement and shall also entitle Landlord's
representative to be present at all design and development meetings coordinating
completion of the Tenant Improvements. Tenant shall deliver to TI Architect
reasonably sufficient information and instructions to enable TI Architect to
prepare preliminary plans and specifications for construction of the Tenant
Improvements desired by Tenant. All fees and expenses charged by the TI
Architect in connection with the Tenant Improvements shall be charged against
the improvement Allowance described in Section 3.02. All preliminary and final
plans and specifications for the Tenant Improvements shall be subject to
Tenant's and Landlord's approval, which approval shall not be unreasonably
withheld, conditioned or delayed. Tenant and TI Architect shall develop the
final plans and specifications for the Tenant Improvements (the "TENANT
IMPROVEMENTS FINAL PLANS AND SPECIFICATIONS"). Tenant and TI Architect shall use
their best efforts to complete the plan preparation and approval process within
the time periods shown on the Development Schedule. Failure by either Tenant or
TI Architect to comply with the plan preparation and approval process within the
time periods shown on the Development Schedule will constitute a Tenant Delay.
Concurrently with preparation of the Tenant Improvements Final Plans and
Specifications, the TI Contractor (hereinafter defined) shall prepare for
Tenant's review and approval an estimated budget for the Tenant Improvements.
Upon receipt of Tenant's written comments with respect to the estimated budget,
the TI Contractor shall promptly modify the estimated budget and deliver a
revised budget to Tenant for its approval. In addition, TI Architect shall
promptly modify the Tenant Improvements Final Plans and Specifications to
accommodate the requested changes to the estimated budget. From time to time
during the design, bidding and construction stages, upon Tenant's request,
Landlord, TI Architect and the TI Contractor shall make value engineering
recommendations and shall otherwise advise Tenant with regard to methods of
reducing the total cost of construction of the Tenant Improvements. Tenant shall
have the sole option of whether to

                                       5
<PAGE>   13

accept or reject any value engineering recommendations. All costs involved in
approving, drafting and preparing the Tenant Improvements Final Plans and
Specifications shall be charged against the Improvement Allowance described in
Section 3.02 hereof.

        Section 2.04 BIDDING. After final, written approval by Tenant of the
estimated budget for the Tenant Improvements and of the Tenant Improvements
Final Plans and Specifications, the Landlord shall solicit at least three (3)
bids (or as many as reasonably practical) from general contractors unaffiliated
with Landlord or Tenant (some of whom may be recommended by Tenant) and shall
contract (with Tenant's approval, which approval shall not be unreasonably
withheld, conditioned or delayed) with a general contractor (the "TI
CONTRACTOR"), which shall act as the general contractor for the Tenant
Improvements work. Tenant shall be entitled to supply to Landlord, for use by
the TI Contractor, a list of approved subcontractors to whom the Tenant wishes
to be delivered bid packages in connection with certain components of the Tenant
Improvements. All fees, supervision, costs and charges relating to the Tenant
Improvements including, without limitation, all architectural and engineering
fees and other "soft costs," shall be charged against the Improvement Allowance
described in Section 3.02 hereof. TI Contractor, with the advice and consent of
Landlord and Tenant, shall select the respective subcontractors within seven (7)
days after its receipt of all of the bids for the respective work; however, if
all of the subcontractors' bids received for any portion of the Tenant
Improvements work exceed the estimated budget for such work, or if some or all
of the bids which have been received are within the budget but are otherwise
unsatisfactory to Landlord or Tenant, then Landlord or Tenant may, in writing,
within seven (7) days after the receipt of the respective bids, either request
modification of the plans and specifications for the subject portion of the
Tenant Improvements or request that the TI Contractor solicit additional
subcontractor bids. If such modifications or requests for solicitation of
additional bids are made by Tenant and will result in delays in completion of
construction of the Tenant Improvements, Landlord shall immediately notify
Tenant, in writing, of the amount of anticipated delay, which shall be deemed a
Tenant Delay (as hereinafter defined). If Landlord fails to notify Tenant of any
delay which may result from such modifications or solicitation of additional
bids within seven (7) days of Tenant's request therefor, then any delay
resulting therefrom shall not be deemed a Tenant Delay.

        SECTION 2.05 CONSTRUCTION. The Contractor shall construct the Base
Building Work promptly, and in accordance with the requirements of all Covenants
and Laws and the standards expressed in Section 2.02. The TI Contractor shall
construct the Tenant Improvements promptly, in a good and workmanlike manner and
in substantial accordance with the Tenant Improvements Final Plans and
Specifications. Landlord shall be responsible for causing the Contractor, TI
Contractor and Architect (but not the TI Architect) to perform all of their
respective obligations described in this Lease pursuant to written contracts,
the terns of which shall be in accordance with the terns and provisions hereof
and the requirements of all Covenants and Laws. In addition, an affiliate of
Landlord, Koll Development Company, LLC ("KOLL") shall guarantee the Landlord's
obligations under this Section 2.05 by execution of the Completion Guaranty
attached hereto as Exhibit "D." Landlord shall use commercially reasonable
efforts to work with the City of Plano, Texas to assist Tenant and Tenant's
broker in acquiring the municipal incentives which may reduce the cost of
Tenant's occupancy of the Project. Any municipal incentives which are achieved
through

                                       6
<PAGE>   14

the efforts of Landlord, Tenant or Tenant's broker shall inure to the benefit of
the Tenant, to the extent that the Tenant continues to occupy the Project.

        Section 2.06 SUBSTANTIAL COMPLETION. The Base Building Work and Tenant
Improvements shall be deemed substantially completed (hereinafter,
"SUBSTANTIALLY COMPLETED" or "SUBSTANTIAL COMPLETION") upon the completion of
the Base Building Work and the Tenant Improvements, such that only minor or
insubstantial details of construction or mechanical adjustment remain to be
performed, the existence of which do not materially interfere with Tenant's
occupancy and use of the Building for the conduct of Tenant's business, and upon
the issuance of a temporary or permanent certificate of occupancy by the
governing local authority for the Building. A certificate furnished by Architect
as to the date of Substantial Completion shall be conclusive and binding upon
both parties. Notwithstanding the delivery of such certificate of Substantial
Completion by the Architect, Substantial Completion shall be deemed not to have
occurred with respect to the Base Building Work and Tenant Improvements until
Landlord has provided Tenant prior written notice and at least sixty (60) days
of reasonably unrestricted physical access to the Building for purposes of
Tenant's installation of furniture, fixtures and equipment. Within ninety (90)
days after the date of Substantial Completion, Tenant shall notify Landlord in
writing of any remaining "punch list" or other corrective work to be completed
by Landlord through the Contractor and TI Contractor. Such "punch list" or other
corrective work shall be commenced by Landlord and completed within sixty (60)
days following receipt of such notification from Tenant, or such longer period
of time as is reasonably necessary to permit Landlord to complete such work in
the event that the completion of same is not possible within such sixty (60) day
period with the exercise of reasonable diligence. Upon completion of such "punch
list" and other corrective work to Tenant's, TI Architect's and Architect's
reasonable satisfaction, and upon Tenant's installation of its furniture,
fixtures and equipment, Landlord shall obtain the issuance of a permanent
certificate of occupancy, unless such certificate has previously been obtained.
Landlord shall have no other obligation to perform other work except with regard
to Landlord's obligations to correct construction defects and deficiencies as
provided in Section 2.12 and to maintain certain structural and other elements
of the Project as set forth in Section 15.02. Tenant shall reasonably cooperate
with Landlord in obtaining the temporary and permanent certificates of
occupancy.

        SECTION 2.07 INSPECTION. Tenant may, at its election, perform on-site
inspections of the Base Building Work and the Tenant Improvements from time to
time, provided that such inspections do not interfere with the completion of the
Project by the Landlord. The Tenant agrees to indemnify, defend and hold
Landlord harmless from any loss, cost, liability or damage resulting from any
(i) installation of furniture, fixtures and equipment pursuant to Section 2.06,
and (ii) personal injury resulting from any inspection of the Project by the
Tenant, its employees or agents prior to Substantial Completion, unless arising
out of Landlord's negligence. Landlord shall be responsible for inspecting the
construction work for the Base Building Work and the Tenant Improvements. In
addition, Tenant and its designated agents and representatives shall, upon
Landlord's request (which may occur at regular intervals), inspect a
specifically identified element of the construction work of the Base Building
Work or the Tenant Improvements and Landlord shall cooperate fully with Tenant
and/or its designated agents and representatives during any such inspections. If
Tenant's inspections

                                       7
<PAGE>   15

of a specific element of the Project requested by Landlord result in Tenant
recognizing any occurrence of material deviations from the Base Building Final
Plans and Specifications or from the Tenant Improvements Final Plans and
Specifications approved by Tenant, Tenant shall notify Landlord in writing of
such deviations within seven (7) days of such inspection, and Landlord shall,
upon receipt of such written notice, either respond in writing to objections to
the claim or correct such deviations promptly. However, if Tenant fails to
notify Landlord of any such material deviations within seven (7) days after an
inspection specifically requested by Landlord, Tenant shall be deemed to have
accepted all work relating to the item specifically inspected by Tenant which
has been completed to the date of Tenant's inspection. Landlord shall not be
obligated to uncover work already in place, except upon written request by
Tenant in connection with an inspection of the Building by Tenant. If a material
deviation from the plans and specifications is thereby uncovered, Landlord shall
cause such deviation to be corrected and the costs of the tests, uncovering and
correction, as well as delays caused thereby, shall be Landlord's sole
responsibility. If no material deviation is found, all testing, uncovering and
recovering costs, as well as any delays caused thereby, shall be Tenant's sole
responsibility and sums due therefor shall be payable within twenty (20) days
following written demand by Landlord. Tenant's failure to detect a deviation
from plans or specifications shall not relieve Landlord from its obligation to
cause the Project to be constructed free of design (as to the Base Building Work
only) and construction defects (as to the Base Building Work and the Tenant
Improvements) and in accordance with the approved final plans and
specifications, and to correct any unsafe, illegal or latent defective
conditions in accordance with Section 2.12.

        SECTION 2.08 REPORTS. Landlord shall provide to Tenant periodic
construction reports as the construction of the Project progresses, but no less
frequently than once every thirty (30) days.

        SECTION 2.09 COMPLIANCE WITH LAWS. The Building, including, but not
limited to, the Base Building Work and the Tenant Improvements, shall be
constructed in accordance with Laws (as defined in Section 8.01) and the
Covenants (as defined in Section 13.02). After the Term Commencement Date (as
defined in Section 4.01) for Phase I, and the Project Expansion Commencement
Date for any Project Expansion (as such terms are defined in Article 25), Tenant
shall have sole responsibility for ongoing compliance with all Laws and
Covenants, except to the extent Landlord has responsibility for any such
compliance as set forth in Sections 2.12 or 15.02, in which event Tenant shall
have no responsibility therefor.

        SECTION 2.10 INSURANCE AND RESTORATION. At Landlord's sole cost and
expense and as part of the cost of construction Landlord shall procure or cause
to be procured and maintained during the construction of the Project (including,
without limitation, the construction of Tenant Improvements), builder's risk
insurance insuring the Building and all other improvements constructed on the
Real Property against fire, the perils insured under the standard form extended
coverage endorsement, vandalism, and malicious mischief in the full amount of
the cost of construction. In the event the Building or Tenant Improvements shall
be damaged or destroyed by fire or other insured casualty, Landlord shall repair
or restore the damaged Building, upon Tenant's reaffirmation of the Lease or
giving of such other comfort to Landlord and Lender (as defined in Article 20)
as may be reasonably

                                       8
<PAGE>   16

agreed to between Tenant, Landlord and Lender, which shall be subject to the
conditions provided in this Section 2.10. Landlord shall promptly commence such
repairs and this Lease shall be unaffected except that the Term Commencement
Date (as hereinafter defined) and the Project Expansion Commencement Date for
any Project Expansion shall be extended until the Building is Substantially
Completed; provided, however, in the event (a) the damage is such that
restoration and completion is not reasonably possible within nine (9) months
after the date of the casualty in the opinion of the Third-Party Architect (as
defined in Section 16.02), or (b) Landlord has not Substantially Completed the
restoration of the Building in accordance with the terms hereunder, including,
but not limited to, Tenant Improvements, within twelve (12) months after the
date of the casualty (such time period being extended by up to six (6)
additional months by Force Majeure), then Tenant shall have the right to
terminate this Lease within thirty (30) days thereafter by giving written notice
of such termination to Landlord and, upon such termination, the parties shall
have no further obligations hereunder, one to the other, except for obligations
arising under Section 2.11 hereof. In no event shall Landlord be responsible for
any loss or damage to Tenant's personal property or to improvements installed or
stored by Tenant other than as may be contained within the Tenant Improvements.
The insurance coverage required in this Section 2.10 shall terminate on the Term
Commencement Date for Phase I and the Project Expansion Commencement Date for
any Project Expansion.

        SECTION 2.11 INDEMNITY. Prior to the Term Commencement Date for Phase I,
and the Project Expansion Commencement Date for any Project Expansion, Landlord
shall indemnify, defend and hold Tenant, its officers, directors, agents,
employees, contractors, licensees and invitees, harmless from and against any
and all claims, losses, damages, injuries and liabilities (including the costs
of audit or attorney's fees) arising (a) from the death or injury of any person
or persons, including, but not limited to, the employees of Landlord, Architect
or the Contractor or any subcontractor, and/or (b) from damage or destruction of
any property or properties, where such injuries, death or .damage are caused by
Landlord's sole negligence or the joint negligence of Landlord and any other
person or entity (excluding the Tenant). In addition to the Tenant indemnity
provided in Section 2.07, Tenant shall indemnify, defend and hold Landlord
harmless from and against any and all claims, losses, damages, injuries and
liabilities (including the reasonable costs of suit and attorneys' fees) arising
from (a) replacement of defective work relating to the TI Architect's design
work in connection with the Tenant Improvements, in the event that the TI
Architect fails to correct and/or replace such defective work at TI Architect's
sole cost and expense in accordance with Section 2.12, and (b) any mechanic's
lien or materialmen's lien filed as a result of Tenant's failure to pay sums due
directly by Tenant to the TI Architect with respect to the Tenant Improvements
and to any contractors or subcontractors, if any.

        SECTION 2.12 CORRECTION OF CONSTRUCTION DEFECTS. Landlord, at its sole
cost and expense, shall repair, or cause to be repaired, any deviations, defects
or deficiencies, whether patent or latent, in the Project (as well as any
Project Expansion) and/or Tenant Improvements (including, without limitation,
air conditioning, plumbing, electrical and heating systems) installed by
Landlord or its agents or contractors which are due to faulty design (except
with respect to the design of the Tenant Improvements, for which Tenant shall be
responsible to replace work necessitated by a defective

                                       9
<PAGE>   17

design of any of the Tenant Improvements, in the event that the TI Architect
fails to replace work necessitated by its defective design in accordance with
this provision), defective materials or workmanship in construction thereof for
a period of one (1) year following the Term Commencement Date for Phase I and
for a period of one (1) year following the Project Expansion Commencement Date
for each Project Expansion. Tenant covenants that it shall use commercially
reasonable efforts to cause the TI Architect, in such architect's agreement with
Tenant, to indemnify and hold Landlord harmless from any defective design in the
Tenant Improvements which causes any loss, damage, cost or liability to the
Landlord in construction of the Project. The TI Architect's agreement shall
identify the Landlord as a third-party beneficiary of such agreement to the
extent of the indemnity contained therein. Landlord's primary recourse for
design defects in the Tenant improvements shall be against the TI Architect. In
the event that the architect's agreement with the TI Architect fails to contain
the indemnity of Landlord described in this Section 2.12, or, in the event
Landlord is unsuccessful in recovering all of its losses, costs, liability or
damage from the TI Architect after exercising reasonable efforts, Tenant shall
be responsible for the unrecovered costs of correcting any defective work
resulting from errors in the Tenant Improvements Final Plans and Specifications
caused by the TI Architect. Any and all rights of Landlord in and to any
guaranties or warranties in effect on the first anniversary of the Term
Commencement Date for items, the repair, replacement and/or maintenance of which
Tenant has assumed responsibility under Section 15.01 hereof shall be assigned
to Tenant. This Section shall not limit Landlord's repair requirements for
so-called "punch list" items in accordance with Section 2.06 hereof or its
obligation to maintain Structural Elements as provided in Section 15.02 hereof.

        SECTION 2.13 SCHEDULE. Notwithstanding anything contained in this
Article 2 to the contrary, the right of Tenant hereunder to any review,
approval, or modification of plans, or additional bidding, shall comply with the
Development Schedule [as may be extended for acts of third parties, Landlord
Delays (as defined in Section 2.16) or by Force Majeure], and any delay in the
Development Schedule resulting from Tenant's exercise of such rights in excess
of any time periods specified in this Lease shall be deemed a Tenant Delay.

        SECTION 2.14 CHANGE ORDERS.

        (a) Net Increased Costs. All Net Increased Costs (hereinafter defined)
associated with Change Orders (hereinafter defined) resulting from Tenant
Changes in the Base Building Work or Tenant Improvements shall be Tenant's sole
expense and any delays caused by such Change Orders shall be deemed to be Tenant
Delays. For purposes of this Lease, the term "NET INCREASED COSTS" shall mean
the aggregate positive difference expressed in dollars resulting from Change
Orders approved by Tenant which result in an increase in the cost of the Base
Building Work or Tenant Improvements. Any Change Orders initiated and approved
by Tenant resulting in cost savings shall be credited against those changes
resulting in cost increases for purposes of determining Net Increased Costs. For
purpose of this Lease, the TERM "CHANGE ORDER" SHALL mean (i) a Tenant requested
and approved modification in scope, quality or materials or a change in the
Development Schedule to either the Base Building Work or the Tenant Improvements
or (ii) corrections to the Base Building Final Plans or the Tenant Improvement
Final Plans and Specifications necessitated

                                       10
<PAGE>   18

because of Tenant's errors, inconsistencies or omissions in its submissions to
Landlord. Change Orders shall not include work due to changes in the Base
Building Final Plans and Specifications resulting from Additional Detail, unless
modifications to the Base Building Outline Specifications were necessitated
because of Tenant's errors, inconsistencies or omissions or because the Base
Building Outline Specifications were modified at Tenant's request. Net cost
savings in the Base Building Work or Tenant Improvements below the final bid
price for the Base Building Work or Tenant Improvements due to Change Orders
shall reduce the amount of Base Rent payable in accordance with Section 5.01(c).
Change Orders to the Base Building Work or Tenant Improvements resulting from
either of the events described in subsections (i) or (ii) above shall be
referred to herein as "TENANT CHANGES."

        (b) Base Building Work Tenant Changes. In the event of Net Increased
Costs in the Base Building Work due to Tenant Changes, the actual costs of
construction associated with Tenant Changes, including, but not limited to, (i)
Landlord's overhead administration costs equal to five percent (5%) of the cost
of Tenant Changes, and (ii) reasonable and actual associated soft costs of
Tenant Changes including, but not limited to, title charges, financing costs and
legal expenses, shall be Tenant's sole expense and payable by Tenant to Landlord
within twenty (20) days after Substantial Completion and Tenant's receipt of an
invoice therefor, and any delays caused by such Tenant Changes shall be deemed
to be Tenant Delays. Notwithstanding the foregoing, Tenant may elect to cause
Landlord to fund a certain amount of Net Increased Costs out of the Supplemental
Allowance as set forth in Section 3.04.

        (c) Tenant Improvements Tenant Changes. All Net Increased Costs
associated with Change Orders resulting from Tenant Changes in the Tenant
Improvements in excess of the Improvement Allowance shall be Tenant's sole
expense and any delays caused by such Change Orders shall be Tenant Delays. In
the event of Net Increased Costs in the Tenant Improvements due to Tenant
Changes, the actual costs of such Tenant Changes, including, but not limited to,
(i) Landlord's overhead administration costs equal to five percent (5%) of the
cost of Tenant Changes, and (ii) reasonable and actual associated soft costs of
Tenant Changes including, but not limited to, title charges, financing costs and
legal expenses, shall be Tenant's sole expense and payable by Tenant to Landlord
within twenty (20) days after Substantial Completion and Tenant's receipt of an
invoice therefor, and any delays caused by such Tenant Changes shall be deemed
to be Tenant Delays. Notwithstanding the foregoing, the Tenant may elect to
either (i) cause Landlord to fund a certain amount of Net Increased Costs in
excess of the Improvement Allowance out of the Supplemental Allowance as set
forth in Section 3.04, or (ii) reallocate any items of costs allocated for
Tenant Improvements in the Improvement Allowance to satisfy any increased costs
for which the Tenant may be obligated to pay to Landlord hereunder.

        (d) Classification. All Change Orders requested by Tenant shall be
delivered to Landlord in writing and Architect and TI Architect shall determine
the portion thereof that constitutes Base Building Work and the portion thereof
that constitutes Tenant Improvements. Upon receipt of any

                                       11
<PAGE>   19

Change Order, Landlord shall, as soon as possible but within fourteen (14) days
following receipt thereof. apprise the Tenant in writing of any Tenant Changes
outlined therein, the cost associated with such Change Order and if and to the
extent such Change Order will result in a Tenant Delay.

        SECTION 2.15 FORCE MAJEURE. Whenever a period of time is herein
prescribed for action to be taken by either party hereto, such party shall not
be responsible for and there shall be excluded from the computation of any such
period of time, any delays due to strikes, riots, act of God. inclement weather
in excess of the days set forth in Exhibit "E." war, governmental laws, or
regulations or restrictions ("FORCE MAJEURE"). Any claim of a "Force Majeure"
must be made in writing, by the party making such claim delivered to the other
party within thirty (30) days after the event causing such Force Majeure delay.
In calculating the amount of Force Majeure delays, the parties agree that the
total amount of Force Majeure delays shall include both the actual number of
days resulting from the event and constituting the Force Majeure delays and the
additional number of days resulting in the contractor being unable to recommence
work on the site following the delay due to the fact that the Real Property is
physically inaccessible. The parties further agree that in calculating delays
due to weather, that they shall rely upon the attached Exhibit "E" to determine
if the weather events in question are beyond the standard weather conditions
expected for the site (herein the "WEATHER STANDARD"), and the weather events
within the Weather Standard shall not constitute a Force Majeure delay
hereunder. Force Majeure shall not apply to the payment of any debt or other sum
of money then due or owing hereunder including Base Rent and Additional Rent.

        SECTION 2.16 LANDLORD AND TENANT DELAY.

        (a) The terms "LANDLORD DELAY," "Delays caused by Landlord," "TENANT
DELAY" or "Delays caused by Tenant" shall mean delay in completion of
construction of the Building, the Tenant Improvements and/or the Base Building
Work caused by:

               (i) Unless and to the extent due to the acts or omissions of
        the other party or such party's agents, employees or contractors, the
        respective party's failure to perform its construction period
        obligations by the dates or within the term periods shown in the
        Development Schedule; subject, however, to Force Majeure;

               (ii) Any subsequent changes, modifications or alterations to the
        final plans and specifications for the Base Building Work and/or Tenant
        Improvements initiated by the respective party after final approval by
        Landlord and Tenant, except to the extent any such changes,
        modifications or alterations are required (a) by Laws enacted after the
        date of approval of the final plans and specifications for the Base
        Building Work and/or Tenant Improvements; or (b) for work resulting from
        Additional Detail.

               (iii) Any other act required to be timely performed in accordance
        with the provisions of this Lease which is not timely performed by the
        respective party; and

                                       12
<PAGE>   20

               (iv) Any other act or omission stated in this Lease to be a
        Landlord or Tenant Delay.

        (b) For purposes of determining delay, the terms Landlord and Tenant
shall include their respective contractors, agents and employees; and any delay
caused by a contractor selected or hired by Landlord shall be considered a
Landlord Delay, and any delay caused by a contractor selected and hired by
Tenant pursuant to Section 2.04 shall be considered a Tenant Delay.

        SECTION 2.17 BUILDING MATERIALS. Tenant shall use reasonable efforts not
to request specially fabricated or exotic materials or equipment ("SPECIAL
ORDER") which will delay Landlord's timely construction of the Base Building
Work and the Tenant Improvements and any delay resulting therefrom shall be
deemed to be a Tenant Delay. Within ten (10) days following receipt from Tenant
of a request for a Special Order, Landlord shall give written notice to Tenant,
prior to acceptance of a Special Order, specifying the approximate time of
delay, and the parties shall negotiate in good faith to seek a mutual agreement
as to whether such Special Order will be accepted.

        SECTION 2.18 SIGNAGE. During the Term of this Lease, Tenant shall have
the exclusive right to Tenant's corporation identification on the Building and
monument signage (to the extent permitted by Laws and Covenants) located on the
Real Property. To the extent installation of Tenant's signage adversely affects
the structural integrity of the Project or any component thereof, such signage
is subject to Landlord's consent, which consent shall not be unreasonably
withheld. All such signage shall comply with Laws and Covenants.

        SECTION 2.19 ACCESS. During the Term of this Lease, Tenant may use the
roof of the Building to install communications equipment, and the roof and
easements located within the Project to connect cabling under the Building for
telecommunication equipment (including satellite disk, antenna, microwave dish
and fiber optics), at Tenant's expense, provided such use complies with Laws and
does not violate Covenants. Tenant shall be permitted to place communications
equipment on the roof, as long as the equipment does not exceed the structural
capacity of the roof, and is approved as to size and location by Landlord, which
approval shall not be unreasonably withheld. Upon receipt of Tenant's request to
place communications equipment on the roof of the Building, in the event
Landlord fails to respond within thirty (30) days thereafter, such request of
Tenant shall be deemed approved. Tenant shall be solely responsible for any
damage caused by the placement of communications equipment on the roof. Any
penetrations of the roof membrane necessitated by the installation of such
equipment shall be made by the roofing contractor (including related
maintenance, repair and replacement) who installed the roof system, or such
other roofing contractor authorized by the manufacturer to perform warranty work
on the roof system installed at the Project, and any damage or loss of warranty
resulting therefrom shall be Tenant's responsibility, notwithstanding the
provisions of Section 15.02.

        SECTION 3.01 BASE BUILDING WORK. All costs and expenses of construction
of the Base Building Work (excluding costs related to Net Increased Costs of
Tenant Changes and Tenant Delays and the cost of payment and performance bonds
if requested by Tenant) shall be borne by Landlord. All preliminary and final
cost estimates submitted for Tenant's approval by the Contractor, TI Contractor
and/or Landlord shall specifically identify which costs constitute Tenant
Improvements costs which shall be the subject of the Improvement Allowance
provided in Section 3.02.

        SECTION 3.02 TENANT IMPROVEMENT ALLOWANCES. Tenant shall bear the costs

Improvements construction or design costs shall, subject to finalization by
Landlord and Tenant of invoices for all Tenant Improvements work, if Tenant is
not then in default beyond applicable grace periods, be paid to Tenant within
thirty (30) days of Tenant's written request therefor, or in Tenant's sole
discretion, may be applied by Tenant to other costs in connection herewith;
provided, however, Tenant agrees to reimburse Landlord for any additional bills
that are subsequently received by Landlord within ninety (90) days following
Substantial Completion for Tenant Improvements work. Such reimbursement shall be
made by Tenant within twenty (20) days after receipt of Landlord's written
request therefor accompanied by a certified invoice from Landlord accompanied by
applicable bills received. Construction costs on Tenant Improvements in excess
of the Improvement Allowance shall be paid for by Tenant in accordance with
Section 2.14(c) and Section 3.03. Landlord shall provide Tenant with an

expense, and such expense shall be charged against the Improvement Allowance.
Notwithstanding anything contained herein to the contrary, the following amounts
shall not be charged against the Improvement Allowance:

        (i)    payment for any work which is a portion of the Base Building
               Work, including all soft costs related to same;

<PAGE>   22

        (iv)   demolition and removal of non-conforming work installed by the TI
               Contractor including but not limited to replacement of defective
               materials and workmanship (unless necessitated by an error or
               omission of the TI Architect, in which event the provisions of
               Section 2.12 shall control payment of the costs incurred in
               replacement of defective materials and workmanship);

        (v)    expediting and overtime costs specifically due to Landlord's or
               TI Contractor's negligence or Landlord Delays;

               Improvement Allowance);

        (vii)  use and reasonable access to vertical transportation;

        (viii) repair or correction to Building equipment systems unless caused
               by Tenant;

        (ix)   removal of debris or stored materials from the Project except in
               connection with Tenant Improvements work;

        (x)    performance and payment bonds if required by Landlord;

        (xi)   builders risk insurance; and

        (xii)  premiums associated with liquidated damage requirements of

        SECTION 3.03 PAYMENT. Payments of amounts up to but not in excess of the
Improvement Allowance shall be made and disbursed by Landlord to (i) the TI
Contractor in accordance with the provisions of the contract with the TI
Contractor or (ii) to Tenant or to any subcontractor directly contracting with
Tenant which has been approved by Landlord. Prior to the Term Commencement Date
and the Project Expansion Commencement Date for any Project Expansion, if
applicable, Tenant shall not be entitled to draw more than twenty percent (20%)
of the Improvement Allowance for items which are not shown in the Tenant
Improvements Final Plans and Specifications. Disbursements of the Improvement
Allowance to any party, including the TI Contractor or to any subcontractor who
contracts directly with the Tenant, shall be made thirty (30) days following
delivery of a draw request and supporting documentation and must satisfy any
documentation requirements reasonably imposed by the Lender, including, but not
limited to, partial and/or final lien waivers and releases. Landlord shall
provide Tenant the right and opportunity, upon reasonable request, to review
Landlord's records and accounting for disbursements of amounts paid or payable
under the Improvement Allowance and shall report to Tenant, in a form reasonably
acceptable to Tenant, the amounts expended during the course of completion of
the Tenant Improvements. Within thirty (30) days of receipt of a certified
invoice therefor from Landlord together with copies of applicable bills, Tenant
shall pay those costs of construction of the Tenant Improvements in excess

                                       15
<PAGE>   23

of the Improvement Allowance, if any. If Tenant fails to pay the invoiced costs
within such thirty (30) day period, then interest shall commence accruing on the
thirty-first (31st) day and shall continue until paid at the lesser of (i) two
percent (2%) per annum in excess of the prime rate of interest of Bank One,
Texas, N.A. or (ii) the maximum rate of nonusurious interest permitted by Texas
law (the "SPECIFIED RATE"). All invoiced costs and accrued interest shall be
deemed Additional Rent (as defined in Section 5.04) for purposes of this Lease.

        SECTION 3.04 SUPPLEMENTAL ALLOWANCE. Upon the election of Tenant (which
may only be exercised with respect to Phase I and must be done prior to the Term
Commencement Date), and written verification from the Guarantor that it consents
to such election by Tenant and Guarantor agrees to be bound thereby, Landlord
shall provide a supplementary improvement allowance (the "SUPPLEMENTAL
ALLOWANCE") of up to Two Million and No/100 Dollars ($2,000,000.00) to cover
Change Orders or Tenant Changes in the Base Building Work or the Tenant
Improvements. The Tenant may not elect to receive such money directly in cash.
In addition, the Supplemental Allowance may be used for payment of, without
limitation, architectural and engineering fees and other third party payments
for professional services incurred in connection with the completion of the
Project. All fundings of the Supplemental Allowance will include Landlord's
overhead administration costs equal to five percent (5%) of the amount of
Supplemental Allowance expended, and additional reasonable costs actually
incurred by Landlord as a result of Tenant's utilization of the Supplemental
Allowance, such as incremental costs of borrowing (e.g., interest carry incurred
by Landlord from the time of such draw of the applicable portion of the
Supplemental Allowance until the commencement of the payment of increase in the
Base Rent related thereto, additional title premiums, legal expenses and similar
costs relating to additional borrowings). In the event Tenant elects to receive
the Supplemental Allowance, the Base Rent shall increase as provided in Section
5.01(c).

                          ARTICLE 4 - TERM AND RENEWALS

        SECTION 4.01 TERM. The term of this Lease (the "TERM") shall be for a
period often (10) years commencing on the earliest to occur of (a) the date of
Tenant's occupancy of all or any part of the Phase I Building for the conduct of
its business; (b) ten (10) days after the date the Base Building Work and the
Tenant Improvements for Phase I are Substantially Completed; or (c) the date the
Base Building Work and the Tenant Improvements for Phase I would have been
Substantially Completed but for Tenant Delays (the "TERM COMMENCEMENT DATE").
The Term shall be extended by the exercise by the Tenant of its rights under
Sections 4.02 and 25.03(e). Base Rent, Additional Rent, and other costs
described herein for Phase I which are associated with the use of the Building
shall commence on the Term Commencement Date, but in no event earlier than June
1, 2001. Tenant shall have the right for a period of sixty (60) days prior to
Substantial Completion, or earlier if in Landlord's reasonable judgment such
entry and installation would not interfere with the progress of construction, to
enter the Building and install Tenant's furniture, equipment, communications
cabling and fixtures, and may equip completed portions of the Project at an
earlier date if any of such activity

                                       16
<PAGE>   24

Would not unreasonably interfere with remaining construction activities.
Landlord shall use its best efforts to give Tenant twenty (20) days advance
written notice of the date on which Tenant may commence installation of its
furniture and equipment. Once the Term Commencement Date is ascertained,
Landlord and Tenant shall promptly execute a letter specifying such date.

        SECTION 4.02 RENEWAL OPTIONS.

        (a) Tenant, at its option, may, if it has not committed an uncured Event
of Default (as defined in Article 21), either at the time it gives its notice
hereunder to Landlord or at the time of commencement of the respective extended
term, extend the Term of this Lease for the Project for up to two (2) additional
five (5) year terms. Notwithstanding anything in this Lease to the contrary, if
the Term of this Lease, as extended by the provisions of this Section 4.02 or
Section 25.03(e), shall exceed twenty (20) years, Base Rent payable for each
year of this Lease beyond such twenty (20) year period shall increase by two
percent (2%) per annum. A schedule of Base Rent per square foot of Rentable Area
for the maximum permissible Term of this Lease, including periods beyond such
twenty (20) year period, is attached hereto as Exhibit "H." This Lease shall be
extended effective upon (i) the expiration of the previous respective term, and
(ii) Landlord's receipt of written verification that the Guarantor agrees to the
exercise of such renewal options and that the Guarantor shall guarantee the
obligations of the Tenant with respect thereto. Within thirty (30) days after
the receipt by Landlord of Tenant's notice and Guarantor's verification,
Landlord and Tenant covenant that they shall execute an agreement memorializing
the exercise of the First Renewal Term or Second Renewal Term. The first such
extended term (the "FIRST RENEWAL TERM") shall commence upon the expiration date
of the initial term of this Lease, expire upon the fifth (5th) anniversary of
said date, and be upon the same terms, covenants and conditions as provided in
this Lease for the initial term, except that the Base Rent payable during the
First Renewal Term for Phase I and each Project Expansion, if any, shall be
calculated in accordance with Exhibit "H." as modified by Section 5.01 (c) and
Article 25. The second such extended term (the "SECOND RENEWAL TERM"), if
exercised by Tenant and conditioned upon Tenant's exercise of its first option
to extend, shall commence upon the expiration date of the First Renewal Term of
this Lease and expire upon the fifth (5th) anniversary of said date, and be upon
the same terms, covenants and conditions as provided in this Lease for the
initial term, except that the Base Rent payable during the Second Renewal Term
for Phase I and each Project Expansion, if any, shall be calculated in
accordance with Exhibit "H." as modified by Section 5.01(c)and Article 25.

        (b) In order to exercise such renewal options, Tenant shall advise
Landlord in writing at least twelve (12) months prior to the end of the initial
term, or First Renewal Term, as the case may be, that Tenant intends to exercise
its option to renew this Lease.

        (c) Payment of all Additional Rent and other payments required to be
made by Tenant as provided in this Lease for the initial term shall continue to
be made during such extended term. Any termination of this Lease during the
initial term shall terminate all rights of extension hereunder.

                                       17
<PAGE>   25

        SECTION 4.03 REFURBISHMENT ALLOWANCE. Provided Tenant has not committed
an uncured Event of Default at the time it gives notice hereunder. upon the
election of the Tenant (which may only be exercised with respect to Phase I and
which must be elected simultaneously with the delivery of the renewal notice for
the First Renewal Term with respect to the Project), Landlord shall provide to
Tenant, within thirty (30) days following the execution by Landlord and Tenant
of an agreement memorializing the exercise of the First Renewal Term, and
written verification from the Guarantor that it consents to such election by
Tenant and Guarantor agrees to be bound thereby, a refurbishment allowance (the
"REFURBISHMENT ALLOWANCE") of up to Ten and No/100 Dollars ($10.00) per square
foot of Rentable Area in Phase I, which may be used by Tenant for cleaning,
replacements, renovations, repairs and upgrades to the Project in accordance
with Tenant's discretion. Upon the funding of the Refurbishment Allowance, Base
Rent shall increase as provided in Section 5.01(c). Notwithstanding anything
contained herein to the contrary, the Refurbishment Allowance may only be used
by the Tenant to improve, renovate and/or redecorate the Project and Tenant may
not elect to receive such money directly in cash.

                                ARTICLE 5 - RENT

        SECTION 5.01 RENT.

        (a) Tenant covenants and agrees to pay to Landlord at its address for
notice, in lawful money of the United States, without demand, abatement, offset
or deduction, except as expressly permitted by the terms of this Lease, base
annual rentals for Phase I (the "BASE RENT") equal to the product of Fourteen
and 81/100 Dollars ($14.81) times the Rentable Area of the Building for years 1
through 5 ("LEASE PERIOD 1"); and the product of Sixteen and 29/100 Dollars
($16.29) times the Rentable Area for years 6 through 10 ("LEASE PERIOD 2"). Such
Base Rent shall be payable in advance in equal monthly installments during the
initial term of this Lease commencing on the Term Commencement Date. Any partial
month's Base Rent shall be prorated based on the actual number of days in the
partial month Base Rent is payable. Upon final measurement of Phase I, as
provided for in Section 1.01, Landlord and Tenant shall promptly execute
amendments to this Lease specifically setting forth the aggregate amounts of
Base Rent payable hereunder.

        (b) Base Rent for any Project Expansion shall be calculated in
accordance with Article 25 of this Lease.

        (c) (i) In the event that Tenant elects to utilize the Supplemental
Allowance for payment of any of the Change Orders or Tenant Changes associated
with Base Building Work or the Tenant Improvements (as described in Section
3.04), the Base Rent shall increase in Lease Period 1 by the amount of Ten Cents
(10(cent)) per square foot of Rentable Area per year for each One Dollar ($1.00)
per square foot of Supplemental Allowance utilized, Eleven Cents (11(cent)) per
square foot of Rentable Area per year for Lease Period 2, Twelve Cents
(12(cent)) per square foot of Rentable Area per year for the First Renewal Term
and Thirteen Cents (13(cent)) per square foot of Rentable Area

                                       18
<PAGE>   26

per year for the Second Renewal Term. In other words, if Tenant elects to
receive a Supplemental Allowance of Three Dollars and No/100 Dollars ($3.00) per
square foot of Rentable Area. the initial Base Rent shall increase by the amount
of Thirty Cents (30(cent)) per square foot of Rentable Area per year for Lease
Period 1, and shall increase correspondingly for Lease Period 2, the First
Renewal Term and Second Renewal Term.

                (ii) In the event that the Tenant elects to utilize the
Refurbishment Allowance for renovation of any of the Project (as defined in
Section 4.03), the Base Rent shall increase during the First Renewal Term by the
amount of Twelve Cents ($0.12) per square foot of Rentable Area per year for
each One and No/100 Dollars ($1.00) per square foot of Refurbishment Allowance
utilized and Thirteen Cents ($0.13) per square foot of Rentable Area per year
for the Second Renewal Term.

                (iii) In the event that any of the Tenant approved Change Orders
reduce the cost of the Base Building Work below the final bid price approved by
Landlord and Tenant or the final funded amount of the Improvement Allowance is
less than Thirty and No/100 Dollars ($30.00) per square foot of Rentable Area,
the Base Rent shall be reduced during the Term by the amount of Ten Cents
($0.10) per square foot of Rentable Area per year for each One Dollar and No/100
Dollars ($1.00) per square foot that (i) the final bid price for the Base
Building Work is reduced by Tenant approved Change Orders or (ii) the funded
Improvement Allowance is less than Thirty and No/100 Dollars ($30.00) per square
foot of Rentable Area.

        SECTION 5.02 LATE CHARGE. If Tenant fails to pay when due any
installment of Base Rent or Additional Rent within ten (10) days after the date
the payment is due, Tenant shall pay a late charge equal to five percent (5%) of
the delinquent rent payment. For the first occurrence of a late payment of Base
Rent or Additional Rent. in any lease year during the Term of this Lease and
provided Tenant is not otherwise in default of its obligations under this Lease,
Landlord agrees it will waive receipt of such late charge and such late charge
payment will be made by Tenant for the second and any subsequent late payments
of Base Rent or Additional Rent. Such late charge shall be paid with the next
accruing rental installment and shall be deemed rent for purposes of this Lease.
Base Rent that is more than fifteen (15) days past due shall also accrue
interest at the Specified Rate (as defined in Section 3.03).

        SECTION 5.03 NET LEASE. It is the intention of Landlord and Tenant that,
except for the obligations, costs and expenses expressly assumed by Landlord in
this Lease, including but not limited to the requirements of Section 15.02, all
rentals paid to Landlord in accordance with the terms of this Lease shall be
absolutely net; that is, except as specifically provided for herein to the
contrary, all costs, expenses and obligations of every kind relating directly
or indirectly in any way, foreseen or unforeseen, to Tenant's use, occupancy and
possession of the Project, which may arise or become due during the Term shall
be paid by Tenant and Landlord shall be indemnified by Tenant therefrom,
including, without limitation, all taxes, assessments, excises, levies and other
charges by any public authority which are general or special, ordinary or
extraordinary, foreseen or unforeseen, of any kind and nature whatsoever, except
as expressly set forth to the contrary in Section 9.02, and

                                       19
<PAGE>   27

which shall or may, during or in respect to the Term, be assessed levied,
charged, confirmed or enforced upon, or become due and payable out of, or become
a lien on the Project, or appurtenances or facilities used in connection with
the Project.

        SECTION 5.04 ADDITIONAL RENT. Any and all payments of any kind
(including, without limitation. taxes, insurance premiums, maintenance
obligations and utilities) required to be made by Tenant under this Lease, other
than Base Rent, shall be classified as additional rent due and owing hereunder
("ADDITIONAL RENT"), and failure to pay Additional Rent when due shall
constitute an Event of Default. Landlord shall provide to Tenant written notice
of the requirement of payment of amounts deemed Additional Rent hereunder and
failure of Tenant to pay such amounts within thirty (30} days following receipt
of such notice from Landlord shall constitute an Event of Default.

                            ARTICLE 6 - HOLDING OVER

        SECTION 6.01 HOLDING OVER. Any holding over by Tenant after the
expiration of the Term, or any extension thereof, shall be construed as a
tenancy from month-to-month upon the same terms and conditions as set forth
herein, except that monthly installments of Base Rent shall be equal to one
hundred twenty-five (125%) percent of the monthly installments of Base Rent in
effect during the last calendar month prior to the expiration of the Term or any
extension, as appropriate, for the first six (6) months following expiration of
the Term, with such amount then increasing to one hundred fifty (150%) percent
of the monthly installments of Base Rent in effect during the last calendar
month prior to expiration of the Term or extension, as appropriate. Either
Landlord or Tenant may terminate such month-to-month tenancy upon thirty (30)
days written notice to the other.

                          ARTICLE 7 - QUIET POSSESSION

        SECTION 7.01 QUIET POSSESSION. Provided Tenant is not then in default
beyond applicable cure periods, Landlord covenants and agrees, subject to the
Permitted Exceptions, to keep Tenant in quiet possession and enjoyment of the
Project during the Term and any extensions thereof and warrants that it has full
power and authority to lease the Project to Tenant for the Term and any
extensions thereof.

                           ARTICLE 8 - USE OF BUILDING

        SECTION 8.01 USE. Tenant shall specifically have the right to use the
Building only for any lawful business purposes in accordance with applicable
laws, statutes, ordinances, codes, rules and regulations of all governmental
bodies (state, federal and municipal) (collectively, the "LAWS"), the Permitted
Exceptions and permitted by the Covenants (as defined in Section 13.02)
affecting the Building. Landlord hereby represents as of the date hereof that
the Laws and Covenants would not prohibit the use of the Building for general
office purposes. Landlord represents and covenants that, as of the date hereof
and throughout the Term of this Lease, it shall not file, cause to be filed, or

                                       20
<PAGE>   28

consent to the filing of, any additional Covenants which restrict Tenant's use
of the Building or the Project, or otherwise increase or affect Tenant's rights
hereunder without Tenant's prior written consent, which consent may be withheld
in Tenant's sole discretion.

        SECTION 8.02 MAINTENANCE.

        (a) Tenant shall use the Project in a careful, safe, and proper manner;
and Tenant covenants, except as provided herein to the contrary, to keep,
maintain and be responsible for routine maintenance and repair and replacement
of all elements (except Structural Elements, as defined in Section 15.02) of the
Project and to keep such elements in reasonably good condition and repair,
including, without limitation, HVAC, plumbing, mechanical and electrical; and,
with respect to Tenant's use of the Project, the Building and appurtenances,
Tenant covenants to comply with all applicable Covenants and Laws, including,
without limitation, the Americans with Disabilities Act of 1990, and any and all
Environmental Laws (as defined in Section 24.01(a)(ii)). After Substantial
Completion, Tenant, at its cost, shall manage all aspects of the Project (it
being understood that Landlord shall have no management responsibility
hereunder) and shall maintain the Project in compliance with all Covenants and
Laws; provided, that alterations to the Project required by Covenants and Laws
which involve Structural Elements shall be Landlord's cost and responsibility,
unless such modification to a Structural Element is necessitated by Tenant's
special or unique use of the Project, or Tenant's change in use of the Project
which requires alterations to the Project or any part thereof. Tenant shall be
liable for and shall promptly cause the repair of any damage to the Project to
the extent caused by Tenant, its employees, contractors, agents or invitees,
unless such damage is specifically required herein to be repaired by Landlord
and, to the extent that Landlord, its employees, contractors, agents or invitees
have caused the damage, Landlord shall cause it to be repaired. Tenant shall not
commit waste or suffer or permit waste to be committed or to allow or permit any
nuisance in the Project. Tenant shall not use the Building or allow or permit
the Building to be used for any purposes which may render the Building
uninsurable at normal rates by responsible insurance carriers authorized to do
business in the State of Texas unless Tenant shall pay the extra cost thereof,
or which may render void or voidable any insurance on the Building. Except as
provided herein, Tenant shall not erect, place, allow to be placed any sign,
advertising matter, stand, booth, or showcase in or upon the doorsteps,
vestibules, doors, exterior walls, windows, or pavement of the Building without
the prior written consent of Landlord, which consent shall not be unreasonably
withheld, or which may violate any of the Covenants. Tenant covenants and agrees
that it shall not overload the floors or surpass the utility specifications of
the Building, as reasonably determined by Landlord.

        (b) Notwithstanding anything contained above to the contrary, if Tenant
is required to make a capital improvement in satisfaction of its obligations
hereunder to any item that is described in the Base Building Final Plans and
Specifications, and if the useful life of such capital improvement as provided
by the Internal Revenue Code and Regulations cannot be fully amortized over the
remainder of the Term, Tenant shall so notify Landlord. Upon receipt of such
notice, Landlord shall either (i) direct Tenant that Landlord elects not to
cause Tenant to make such capital expenditure and Tenant shall thereby be
relieved of any liability for such replacement obligation,

                                       21
<PAGE>   29

in which event Tenant may repair such item without, except as hereinafter
provided in subsection (ii) hereof, reimbursement from Landlord and satisfy its
obligations under this Lease, or (ii) direct Tenant to make such capital
expenditure, in which event Tenant shall be reimbursed by Landlord (unless
Tenant caused such damage to occur, in which event Tenant shall not be
reimbursed by Landlord) at the end of the Term for that portion of the
replacement cost that is represented by the extent to which the useful life
(determined in accordance with the Internal Revenue Code and Regulations)
thereof extends beyond the expiration of the Term, which portion shall be
determined by dividing the number of months of useful life of the replacement
that extend beyond the expiration of the Term by the total number months of
useful life of the replacement and multiplying the resultant percentage
calculation against the total cost of the replacement. If the cost of repairing
any item described in the Base Building Final Plans and Specifications by Tenant
as required under this Section 8.02(b) (i) is so extensive that the cost would,
in the opinion of the Third Party Architect (as defined in Section 16.02),
exceed seventy-five percent (75%) of the cost to replace such item, then Tenant
shall replace such item and the provisions of subsection (ii) herein shall apply
with respect to said replacement costs.

                                ARTICLE 9 - TAXES

        SECTION 9.01 PERSONAL PROPERTY TAXES. Tenant shall pay before
delinquency all taxes and assessments, special or otherwise, of any nature that
become payable during the Term and/or any extension thereof which are levied or
assessed upon Tenant's equipment, furniture, fixtures and Tenant's other
personal property installed or located in or on the Project.

        SECTION 9.02 AD VALOREM TAXES. All ad valorem taxes, assessments,
business taxes, impact fees, rental taxes ("RENTAL TAXES") or other similar
rates and taxes levied or imposed upon the Project, or any part thereof, shall
be paid by Tenant, and shall be considered Additional Rent hereunder. Tenant's
sole obligation to pay Rental Taxes shall arise only in the event such taxes are
imposed upon the gross income of the Project and are not denominated as an
"income tax" or other tax imposed on the net income of the Landlord, giving
credit for deduction, depreciation and other reductions to the gross income
attributable to the Project. Nothing contained in this Lease shall require
Tenant to pay any local, county, municipal, state or federal income, franchise,
corporate, estate, inheritance, succession or transfer tax of Landlord. Upon
receipt by Landlord from any association, governmental agency or authority of
statements for ad valorem taxes and assessments against the Project during the
Term and any extension thereof, Landlord shall promptly submit to Tenant an
invoice for such taxes and assessments, together with copies of the original
statements from each taxing authority. Tenant shall pay such invoice to Landlord
no later than twenty (20) days prior to the delinquency date as shown on each
tax statement, but in no event shall it be required to pay the invoice earlier
than thirty (30) days after its receipt; provided, however, Tenant may, in good
faith, contest the assessed valuation of such taxes or assessments, and, receive
a refund from the appropriate governmental authority, if successful, provided
that Tenant shall pay all taxes and amounts due and owing hereunder in
accordance with all applicable laws. Landlord shall reasonably

                                       22
<PAGE>   30

cooperate with Tenant, at no cost to Landlord, in Tenant's appeal. If the Term
Commencement Date or the Project Expansion Commencement Date is on a date other
than January 1, the taxes, assessments, fees or other rates for the first and
last year of the Term shall be prorated. Any and all property tax refunds
accruing to the project shall, during the Term, belong exclusively to Tenant.

        SECTION 9.03 DELINQUENCY OF PAYMENT. If Tenant fails to pay any real or
personal property taxes or assessments in accordance with the terms of this
Article, Landlord shall have the right, after providing thirty (30) days written
notice to Tenant of such failure, to thereafter pay any or all of such taxes and
assessments and Tenant shall reimburse Landlord, within thirty (30) days of
receipt of Landlord's invoice for the amount of such real and personal property
taxes and assessments paid by Landlord together with interest on the amount paid
by Landlord from the date advanced until reimbursed at the Specified Rate. Such
sums shall become rent for the purposes hereof and shall be payable with the
next monthly installment of Base Rent.

                             ARTICLE 10 - INSURANCE

        SECTION 10.01 TENANT'S INSURANCE. Tenant covenants and agrees that from
and after the Term Commencement Date for Phase I and the Project Expansion
Commencement Date for any Project Expansion, Tenant will carry and maintain, at
its sole cost and expense, the following types of insurance, in the amounts
specified and in the forms hereinafter provided for:

        (a) Liability insurance in the Commercial General Liability form (or
reasonable equivalent thereto) covering the Project and Tenant's use thereof
against claims for bodily injury or death, third party property damage and
product liability occurring upon, in or about the Project, such insurance to be
written on an occurrence basis (not a claims made basis), to be in combined
single limit amounts not less than $5,000,000 and to have general aggregate
limits of not less than $10,000,000 for each policy year. The insurance coverage
required under this Section 10.01 shall, in addition, extend to any liability of
Tenant arising out of the indemnities provided for in Section 11.01 and, if
necessary, the policy shall contain a contractual endorsement to that effect;
and

        (b) Insurance covering all of the Tenant's items located in the
Building, including, but not limited to, furniture, fixtures and equipment from
time to time in, on or upon the Project, in an amount not less than one hundred
percent (100%) of their full replacement value from time to time during the
Term, providing protection against perils included within the standard form of
"all-risk" property insurance policy, together with insurance against vandalism
and malicious mischief. Any policy proceeds from such insurance relating to the
Building shall be used solely for the repair, construction and restoration or
replacement of such property damaged or destroyed unless this Lease shall cease
and terminate under the provisions of Article 16.

        SECTION 10.02 POLICY REQUIREMENTS. All policies of the insurance
provided for in Section 10.01 shall be issued in form and content reasonably
acceptable to Landlord by insurance companies with a rating of not less than
"A-" and financial size of not less than Class VII, in the most current
available "Best's Insurance Reports," and licensed to do business in Texas.
Tenant shall

                                       23
<PAGE>   31

provide Landlord with a certificate for each such policy of insurance required
by this Lease. Any insurance coverage required of the Tenant hereunder may be
provided by the Guarantor, as long as such coverage otherwise satisfies the
provisions of this Article 10. Each and every such policy (as evidenced by the
certificate):

       (i) shall name Landlord as well as Lender, as defined in Article 20, and
any other party reasonably designated by Landlord, who has an insurable
interest, as an additional insured. In addition, the coverage described in
Section 10.01(b) relating to the Building shall also name Landlord as loss
payee;

       (ii) shall be delivered to Landlord prior to the Term Commencement Date
and the Project Expansion Commencement Date for any Project Expansion and
thereafter within ten (10) days prior to the scheduled expiration date of each
such policy, within, and, as often as any such policy shall expire or terminate.
Renewal or additional policies shall be procured and maintained by Tenant in
like manner and to like extent;

       (iii) shall contain a provision that the insurer will give to Landlord
and such other parties in interest at least thirty (30) days notice in writing
in advance of any material change, cancellation, termination or lapse, or the
effective date of any reduction in the amounts of insurance; and

       (iv) shall be written as a primary policy which does not contribute to
and is not in excess of coverage which Landlord may carry;

       (v) Landlord and Tenant hereby waive any rights each may have against the
other on account of any loss or damage occasioned to Landlord or Tenant, as the
case may be, their respective property, the Project, its contents or to the
other portions of the Building, arising from any risk covered by "all risk"
property coverage insurance and commercial general liability of the type and
amount required to be carried hereunder, provided that such waiver does not
invalidate such policies or prohibit recovery thereunder and is applicable only
to the extent of receipt of the insurance proceeds. The parties hereto each
agree to use reasonable efforts to cause their respective insurance companies
insuring the property of either Landlord or Tenant against any such loss, to
waive any right of subrogation that such insurers may have against Landlord or
Tenant, as the case may be.

       (vi) Neither Landlord nor Tenant shall take any action that will cause
the premiums for insurance coverage to rise.

       (vii) Any insurance coverage enumerated above may be satisfied by a
blanket policy or policies of insurance or under so-called "all risk" or
"Multi-peril" insurance policies provided that the total amounts of insurance
available with respect to the Project and Tenant's liability hereunder shall be
at least the equivalent of separate policies in the amount herein required, and
provided further that in all other respects any such policy or policies shall
comply with the provisions of this Section 10.02. Tenant shall not, unless
expressly set forth herein to the contrary, have the right to, self-insure
against any of the risks recited herein, except for the amount of any
commercially

                                       24
<PAGE>   32

reasonable deductible (for purposes of this Lease, a deductible amount of
$100,000 shall be deemed to be reasonable). An increased coverage or "umbrella"
policy may be provided and utilized by other parties to increase the coverage
provided by individual or blanket policies in lower amounts and the aggregate
coverage provided by all such policies with respect to the limits required
herein shall be satisfactory, provided that such policies shall otherwise comply
with the provisions of this Section 10.02.

       (viii) Upon receipt of the Landlord's and its Lender's consent, which
consent shall not be unreasonably withheld, conditioned or delayed, the Tenant
may self-insure against any of the risks or portions thereof set forth in this
Section 10.02, provided that the Tenant or Guarantor has an Investment Grade
Credit Rating (as defined in Section 19.01(a)). Landlord and Lender may not
withhold their consent in the event that the Tenant or Guarantor satisfy the net
worth requirements set forth herein and have provided to Landlord and Lender
evidence of a program of self insurance which has been properly adopted and
implemented by the Tenant or Guarantor and which satisfies prudent risk
underwriting practices.

       SECTION 10.03 LANDLORD'S INSURANCE.

       (a) During the Term, Landlord shall maintain, at its sole expense,
liability insurance in the Commercial General Liability form (or reasonable
equivalent thereto) covering the Project and Landlord's use thereof against
claims for bodily injury or death, third party property damage and product
liability occurring upon, in or about the Project, such insurance to be written
on an occurrence basis (not a claims made basis), to be in combined single limit
amounts not less than $3,000,000 and to have general aggregate limits of not
less than $5,000,000 for each policy year. The insurance coverage required under
this Section 10.03 shall, in addition, extend to any liability of Landlord
arising out of the indemnities provided for in Section 11.01 and, if necessary,
the policy shall contain a contractual endorsement to that effect.

       (b) During the Term Landlord shall keep the Project insured against loss
or damage by fire and the perils covered under standard "all-risk," "special
form" coverage in the amount of the full replacement cost of the Building,
exclusive of excavation, footings and foundation, with a commercially reasonable
deductible for which Tenant shall be fully responsible (for purposes of this
Lease, a deductible amount of $100,000 shall be deemed to be reasonable). Lender
and Tenant shall be named in such policy or policies as additional insureds as
their respective interests may appear. All cost of such insurance and payment of
any deductible under such coverage shall be Tenant's expense and shall be deemed
to be Additional Rent under this Lease. Landlord's insurance coverage required
hereunder shall comply with the provisions of Section 10.02 above.

       (c) Upon prior written notice to Landlord and Lender, Lacerte or Intuit
may provide the casualty coverage required by the provisions of Section
10.03(b), at their sole cost and expense. Landlord and its Lender shall be named
as loss payees under the provisions of such coverage and such coverage must
otherwise satisfy the requirements of this Article 10. Neither Lacerte nor
Intuit may self insure against the risks described in Section 10.03(c).

<PAGE>   34

interest, rents, revenues and profits in the Project. Nothing contained herein

       SECTION 13.01 UTILITIES AND SERVICES. From and after the Term
Commencement Date and the Project Expansion Commencement Date for any Project
Expansion, Tenant shall pay the costs and all deposits for all telephone, water,
gas, electricity, sewage, garbage and other services required by Tenant or
supplied to the Project (collectively, the "UTILITY BILLS"). Landlord, at no
expense to Landlord, shall cooperate fully with Tenant in the manner and to the
extent reasonably required by Tenant in obtaining such services for the Project
during the Term. Following the Term Commencement Date and the Project Expansion
Commencement Date for any Project Expansion, Tenant shall have the right to
select the entities which will provide utility services, to the extent
applicable, in its reasonable discretion. If Tenant fails to pay any Utility
Bills when due, Landlord shall have the right, after giving Tenant thirty (30)
days written notice of its failure to pay such Utility Bills, to thereafter pay
such delinquent Utility Bills. Tenant shall reimburse Landlord, within twenty
(20) days of receipt of Landlord's invoice, for the amount of such delinquent
Utility Bills paid by Landlord together with interest on the sums advanced at
the Specified Rate. Such sums shall be considered Additional Rent.

       SECTION 13.02 ASSOCIATION FEES. From and after the Term Commencement Date
and the Project Expansion Commencement Date for any Project Expansion, Tenant
shall pay, prior to delinquency, any assessments and fees assessed against the
Project during the Term and any extension thereof pursuant to that certain

records of Collin County, Texas, as well as all additional amendments thereto
and additional covenants which affect the Real Property (collectively, the
"COVENANTS"). If invoices issued by the applicable association are delivered to
Landlord as owner of the Project, Landlord shall, within thirty (30) days
following receipt thereof, promptly deliver same to Tenant.

                            ARTICLE 14 - ALTERATIONS

       SECTION 14.01 ALTERATIONS. From and after the Term Commencement Date and
the Project Expansion Commencement Date for any Project Expansion, Tenant shall
have the right to make non-structural alterations to the interior of any of the
Building, in order to conduct Tenant's business in the Building, provided such
alterations are of a quality which is equal to or greater than the Base Building
Work, and provided further that Tenant shall make no alterations, other than as
provided below, to the electrical, plumbing or HVAC systems, nor shall any such
alterations require drilling through the Building's slab floors or foundation or
penetrating their roofs without Landlord's consent, such consent not to be
unreasonably withheld. Tenant's request to make alterations to the Building
shall be made in writing and shall describe in sufficient detail the nature of
such proposed alterations and Tenant shall provide Landlord with a complete set
of plans for any proposed structural

                                       27
<PAGE>   35
alterations for its review and approval. Tenant shall not make or suffer to be
made any structural alterations of any kind, on or to the Project, or any part
thereof, without the prior written consent of Landlord, which consent shall not
be unreasonably withheld. Landlord shall, within thirty (30) days following
Tenant's notice of proposed alterations to the Building, either approve such
alterations to the Building or state the reasons for any disapproval with such
additional modifications, which, if remedied by Tenant, shall result in the
Landlord's approval of such proposed alterations. If the Landlord fails to
respond to such notice delivered by Tenant within thirty (30) days following
receipt thereof, Landlord shall be deemed to have approved Tenant's proposed
alterations to the Building. Tenant shall furnish Landlord with plans and
specifications for all alterations, additions or improvements which require
Landlord's consent. All alterations, additions, or improvements constructed by
Tenant shall be constructed in compliance with all Laws and Covenants. Tenant
shall keep the Project free from any liens arising out of any work performed,
materials furnished or obligations incurred by Tenant in connection with such
alterations and, prior to the commencement of any such structural alterations,
in the event the Intuit Guaranty is not in full force and effect, Tenant must
furnish Landlord with payment and performance bonds for Tenant's contractor(s)
in amounts reasonably satisfactory to Landlord, from sureties reasonably
acceptable to Landlord. Tenant may, in good faith, contest the validity of any
mechanic's or materialman's lien and, pending the conclusion of such contest,
Tenant shall not be deemed in default hereunder unless it fails to either pay
the sums due on the lien as determined by the contest or it fails to provide to
Landlord a bond or other acceptable security such that the lien is, by law,
removed from the Project. Landlord shall have the right, but not the obligation,
to post and keep posted on the Project any notice which Landlord may reasonably
deem proper for the protection of Landlord and the Project from such liens.

                       ARTICLE 15 - REPAIR AND MAINTENANCE

       SECTION 15.01 TENANT'S OBLIGATIONS. Except as otherwise specifically
contained within this Lease, including, but not limited to, Section 8.02 hereof,
and in addition to the payment of its monthly installments of Base Rent, Tenant,
at its sole cost and expense, shall cause to be performed all repairs (other
than repairs required herein to be made by Landlord), maintenance, replacements
and, except with respect to Structural Elements (as defined in Section 15.02)
for which Landlord has responsibility, required capital improvements of every
kind, nature or description now or hereafter needed in, on or about the Project
and each part thereof (including, but not limited to, repairs, replacements and
maintenance of the major building systems), whether inside or outside, foreseen
or unforeseen, and Tenant shall keep and maintain both the inside and outside of
the Building and the Project in a first class condition, ordinary wear and tear
and insured casualty excepted. There shall be no abatement, diminution or
reduction of the fixed monthly rental because of any inconvenience,
interruption, cessation or loss of business caused directly or indirectly by
Tenant's obligations hereunder unless Tenant's inability to meet such
obligations is caused by the acts, omissions or negligence of Landlord, its
agents, contractors or employees. In addition to the foregoing, the Landlord
shall be obligated to enforce all contractors' warranties and to pursue all
rights and remedies which the Landlord may have against contractors for work
performed by such contractors, even though pursuit of such warranty obligations
may include a maintenance obligation of the Tenant under this Lease.

                                       28
<PAGE>   36

       SECTION 15.02 LANDLORD'S OBLIGATIONS. Landlord, at its sole cost and
expense, shall maintain in good condition the structural elements of the
Building and shall make all structural repairs and replacements to the Building,
including the structural elements of any parking deck constructed by Landlord as
a portion of the Base Building Work, the roof structure (excluding the roof
membrane), structural elements of the building facade, and the foundation and
load bearing walls (as well as any building and utility systems, including,
without limitation, plumbing, electrical and water systems located beneath or
within the foundation or which are imbedded in any load bearing walls)
(collectively referred to herein as the "STRUCTURAL ELEMENTS"), as Landlord's
sole maintenance, repair or replacement obligation under this Lease (except as
expressly set forth in Section 2.12 to the contrary), unless any such
maintenance, repairs or replacements are necessitated by the acts, omissions or
negligence of Tenant or its agents, contractors or invitees, in which case such
obligations shall be satisfied by Tenant. Landlord shall be obligated to satisfy
all Laws and Covenants with respect to the Structural Elements of the Project,
unless compliance with such Laws and Covenants is Tenant's obligation, as
described in Section 8.02. To the extent that the cause of any of the Landlord's
maintenance, repair or replacement obligations set forth in Section 15.02 also
causes any damage to related portions of the Building which would otherwise be
maintained by Tenant (for example, in the event that the failure of a Structural
Element necessitates a building system repair which would otherwise be the
obligation of the Tenant), then such related damage shall be the obligation of
the Landlord.

       SECTION 15.03 REMOVAL OF FIXTURES. So long as Tenant is not in default
beyond applicable grace periods, Tenant shall have the right at its option to
remove any trade fixtures, machinery, equipment and tenant improvements
installed by Tenant, at its cost (and not those charged against the Supplemental
Allowance or the Improvement Allowance), in the Building at any time during the
Term or when vacating the Building. Tenant shall not remove any Tenant
Improvements unless agreed to in writing by both Landlord and Tenant, which
agreement of Landlord shall not be unreasonably withheld. Tenant shall repair
any damage caused to the Building by reason of the removal of such trade
fixtures, machinery, equipment and tenant improvements. Any trade fixtures,
machinery, equipment or tenant improvements not removed by Tenant shall be
deemed the property of Landlord.

                       ARTICLE 16 - DAMAGE AND DESTRUCTION

       SECTION 16.01 FIRE AND OTHER CASUALTY. In the event that any Building is
damaged by fire or other casualty, Landlord agrees to promptly restore and
repair the Building, including the Tenant Improvements, at Landlord's expense,
but only to the extent Landlord actually receives sufficient insurance proceeds
therefor, from the insurance required to be carried by Landlord and Tenant
hereunder. Tenant agrees to immediately make available to Landlord all proceeds
of any insurance policies covering the Project, excluding that portion of
insurance proceeds applicable to Tenant's personal property and Tenant shall
also be obligated to pay to any insurer providing coverage the amount of any
deductible, retained risk or self insurance amount. Notwithstanding the
foregoing, in the event that the Building is (i) in the reasonable opinion of
Third-Party Architect (as hereinafter defined), so destroyed that it cannot be
repaired or rebuilt within three hundred sixty-five (365) days

                                       29
<PAGE>   37

after the date of such damage (subject to Force Majeure and Tenant Delays); (ii)
destroyed by a casualty which is not covered by insurance, the proceeds of which
are made available to Landlord in accordance with this Section 16.01, or if such
casualty is covered by insurance but such proceeds are insufficient for
restoration of the Project, and only if the Project is thus rendered
untenantable, as determined in the reasonable discretion of Landlord and Tenant;
or (iii) damaged by a casualty event during the last year of the Term which
destroys more than twenty-five percent (25%) of the Rentable Area, and upon
receipt by Landlord of the deductible amount and all insurance proceeds under
the coverages to be provided for casualty damage under Article 10, then Landlord
or Tenant may terminate and cancel this Lease effective as of the date of such
casualty by giving written notice to the other party within thirty (30) days of
the date of such casualty. Upon the giving of such notice, all obligations
hereunder with respect to periods from and after the effective date of
termination shall thereupon cease and terminate except as expressly provided to
the contrary in this Lease. Tenant may obviate Landlord's right to terminate
this Lease in accordance with the provisions of Section 16.01 (iii) in the event
that the Tenant properly exercises a right to renew the Term expressly granted
in accordance with the terms of this Lease. If no such notice is given, Landlord
shall, to the extent of the available insurance proceeds, make such repair or
restoration of the Building to substantially the same condition existing prior
to such casualty, promptly and in such manner as not to unreasonably interfere
with Tenant's use and occupancy of the Project (if Tenant is still occupying the
Project). Base Rent and all Additional Rent and other charges shall abate during
the time that the Building or any part thereof is unusable by reason of any such
damage thereto (and for sixty (60) days following completion of restoration for
the purpose of Tenant refixturing), but only to the extent of any proceeds of
rental loss insurance received by Landlord on account thereof. Tenant shall not
be entitled to any compensation or damages for loss of use of the whole or any
part of the Project and/or any inconvenience or annoyance caused by such damage,
repair or restoration. Notwithstanding anything to the contrary contained
herein, proceeds of any rental loss insurance policies shall be paid to
Landlord, and Tenant shall have no claim therefor.

       SECTION 16.02 THIRD-PARTY ARCHITECT. For purposes of this Lease, the term
"THIRD-PARTY ARCHITECT" shall mean an AIA designated architect licensed in the
State of Texas selected reasonably in good faith by Landlord and Tenant solely
for the purpose of determining certain time periods for restoration or costs in
question under this Lease including, but not limited to, the provisions of this
Article 16. The cost of such Third-Party Architect shall be shared equally by
Landlord and Tenant. In the event that the Landlord and Tenant cannot agree upon
the identity of the Third-Party Architect within fifteen (15) days following a
request for determination by the Third-Party Architect issued by either Landlord
or Tenant, then, upon request of either Landlord or Tenant, the president of the
local chapter of the AIA representative board shall appoint the Third-Party
Architect who shall not be affiliated with either Landlord or Tenant and shall
be experienced in commercial construction for purposes of determining the cost
or period of time required for such restoration or replacement, which
appointment shall be binding upon Landlord and Tenant. The Third-Party Architect
shall be directed, upon request to determine any period of time or cost
hereunder to make such determination within fifteen (15) days following receipt
of such request for a determination by Landlord or Tenant. Any decision rendered
by the Third-Party Architect requested in accordance with this Lease shall be
binding upon the Landlord and Tenant.

                            ARTICLE 17 - CONDEMNATION

       SECTION 17.01 TAKINGS.

       (a) If all of the Project is taken or condemned for a public or
quasi-public use, or if a material portion (defined as twenty percent (20%) or
more of the Project and/or the parking area) of the Project is taken or
condemned for a public or quasi-public use and the remaining portion thereof is
not usable by Tenant in the reasonable opinion of Landlord and Tenant, this
Lease shall terminate on the sixtieth (60th) day following such taking. In such
event, the Base Rent herein reserved and all additional rent and other sums
payable hereunder shall be apportioned and paid in full by Tenant to Landlord to
that date and all Base Rent, additional rent and other sums payable hereunder
prepaid for periods beyond that date shall forthwith be repaid by Landlord to
Tenant, and neither party shall thereafter have any liability hereunder, except
that any obligation or liability of either party, actual or contingent, under
this Lease which has accrued on or prior to such termination date shall survive.

       (b) If less than twenty percent (20%) of the Project and/or the Parking
is taken or condemned for a public or quasi-public use and this Lease does not
terminate pursuant to Section 17.01 (a) and Tenant can occupy and reasonably use
for its intended purposes the remaining portion of the Project, Landlord, to the
extent of the award it receives, shall restore the Project to a condition and to
a size as nearly comparable as reasonably possible to the condition and size
thereof immediately prior to the taking, and there shall be a proportionate
reduction to the Base Rent according to the size of the Project before and after
the taking.

       (c) Landlord shall be entitled to receive the entire award in any
proceeding with respect to any taking provided for in this Section 17.01,
without deduction therefrom for any estate vested in Tenant by this Lease, and
Tenant shall receive no part of such award, except any part of the award
specifically designed to compensate Tenant's costs of moving and business
interruption. Nothing herein contained shall be deemed to prohibit Tenant from
making a separate claim, against the condemnor, to the extent permitted by law,
for Tenant's moveable trade fixtures, machinery and moving expenses, provided
that the making of such claim shall not and does not adversely affect or
diminish Landlord's award.

       (d) Landlord has no actual or constructive knowledge of any pending or
threatened condemnation proceeding.

                         ARTICLE 18 - ENTRY BY LANDLORD

       SECTION 18.01 REASONABLE ACCESS. Subject to Tenant's reasonable security
procedures, Tenant agrees to permit Landlord and the authorized representatives
of Landlord and of Lender to enter upon the Project during normal business hours
(except in the event of emergency) for the purposes of inspecting the Project
and Tenant's compliance with this Lease, and making any necessary repairs
thereto; provided that, except in the case of an emergency, Landlord shall give

                                       31
<PAGE>   39

Tenant twenty-four (24) hours prior written notice of Landlord's intended entry
upon the Project. Nothing herein shall imply any duty upon the part of Landlord
to do any work required of Tenant hereunder, and the performance thereof by
Landlord shall not constitute a waiver of Tenant's default in failing to perform
it. Except in the event of negligence by Landlord, its agents, employees or
contractors, Landlord shall not be liable for inconvenience, annoyance,
disturbance or other damage to Tenant by reason of making such repairs or the
performance of such work in the Project or on account of bringing materials,
supplies and equipment into or through the Project during the course thereof,
and the obligations of Tenant under this Lease shall not thereby be affected;
provided, however that Landlord shall use reasonable efforts not to annoy,
disturb or otherwise interfere with Tenant's operations in the Building in
making such repairs or performing such work. Landlord also shall have the right
to enter the Project at all reasonable times to exhibit the Project to any
prospective purchaser or lender thereof, after reasonable prior written notice
to Tenant.

                     ARTICLE 19 - ASSIGNMENT AND SUBLETTING

       SECTION 19.01 ASSIGNMENT AND SUBLETTING.

       (a) Upon the receipt of Landlord's consent which shall not be
unreasonably withheld, Tenant shall have the right to assign or sublet all or
any part of the Project provided that such assignee assumes in writing the
obligations of Tenant under this Lease, or in the event of a sublease, the
sublessee agrees to subordinate to and be subject to the terms of this Lease.
Tenant shall provide Landlord written notice of any proposed assignment or
subletting, with sufficient detail to apprise Landlord of the material terms of
such assignment of subletting transaction. Within thirty (30) days following
receipt of such written notice, Landlord shall either disapprove or approve such
proposed assignment or subletting transaction, which approval shall not be
unreasonably withheld. In the event that Landlord fails to respond to such
notice delivered by the Tenant within thirty (30) days following receipt of such
written notice, Landlord shall be deemed to have approved the proposed
assignment or subletting transaction proposed by the Tenant. Notwithstanding any
assignment or subletting hereunder, unless expressly set forth in this Article
19 to the contrary, Lacerte and Intuit shall remain liable for the performance
of all of the obligations of Tenant hereunder. Such right of assignment or
subletting by Tenant may also be exercised by any subtenant or assignee of
Tenant which has been previously approved by the Landlord, provided at the time
of exercise of such assignment or subletting Guarantor has an "Investment Grade
Credit Rating." For purpose of this Lease the term "INVESTMENT GRADE CREDIT
RATING" shall mean a credit rating, either on corporate credit or issuances of
indebtedness, for the four (4) most recent fiscal year quarters, as issued by
(i) Standard & Poor's Rating Services equal to or greater than BBB or (ii)
Moody's Investors Services, Inc. equal to or greater than Baa.

       (b) Notwithstanding the foregoing, Tenant shall have the right to assign
this Lease or sublet all or any part of the Project to any entity which
controls, is controlled by, or is in common control of, Lacerte or Intuit
(hereinafter referred to as a "Related Party"). Any assignment or subletting to
such Related Party shall not require consent of the Landlord, but Tenant shall
be obligated to supply Landlord with written notice of such assignment or
subletting, and evidence of the assumption of Tenant's obligations under this
Lease. Such Related Party assignment or

                                       32
<PAGE>   40

subletting shall not relieve Lacerte or Intuit, or their legal successor or
acquiring company, of any liability or obligations under this Lease. If, at any
time during the Term of this Lease, Intuit ceases to exist, Landlord shall have
the right to approve any assignment or subletting transaction entered into
thereafter unless the Guarantor has an Investment Grade Credit Rating, in which
event no approval by Landlord is required. Any purported assignment or
subletting which requires Landlord's consent shall be null and void if made
without such consent.

       SECTION 19.02 ASSIGNMENT BY LANDLORD. Landlord covenants that it shall
not sell or assign its interest in the Project prior to Substantial Completion,
except for any collateral assignment to the Lender. Upon Substantial
Completion, Landlord shall have the right to sell, transfer or assign its
interest hereunder without the prior consent of Tenant, provided that such
purchaser, transferee or assignee assumes, in writing, Landlord's obligations
and liabilities, including any then unfulfilled financial obligation of Landlord
to Tenant hereunder. After such sale, transfer or assignment, Tenant shall
attorn to the new landlord and KCD and Koll shall be released from all
obligations hereunder accruing after the date of such sale, transfer or
assignment.

       SECTION 19.03 NO RIGHT TO RIGHT OF ASSIGNMENT/SUBLEASE INDEPENDENT OF
LEASE. Tenant's (or any subtenant's or assignee's) right to sublease or assign
the Lease shall not be conveyed independently of an assignment or sublease
without the consent of Landlord.

       SECTION 19.04 NO RIGHT TO SEEK EXTENSION UNDER 11 U.S.C. Section 365(d).
Tenant agrees not to seek any extension of time to assume or reject the Lease in
the event of Tenant's (or any subtenant's or assignee's) bankruptcy proceeding
without the consent of Landlord greater than sixty (60) days from the date of
filing any bankruptcy petition.

                ARTICLE 20 - SUBORDINATION AND LENDER AGREEMENTS.

       SECTION 20.01 LENDER AND MORTGAGES.

       (a) For purposes of this Lease:

                  (i) "LENDER" as used herein means the current holder of a
         Mortgage;

                  (ii) "MORTGAGE" as used herein means any or all mortgages,
         deeds to secure debt, deeds of trust or other instruments in the nature
         thereof which may now or hereafter affect or encumber Landlord's title
         to the Project, and any amendments, modifications, extensions or
         renewals thereof.

       (b) This Lease and all rights of Tenant hereunder are and shall be
subject and subordinate to the lien and security interest of any Mortgage.
Tenant recognizes and acknowledges the right of Lender to foreclose or exercise
the power of sale against the Project under any Mortgage, provided that Tenant's
right of quiet enjoyment shall not be disturbed unless and until an Event of
Default occurs under this Lease. As a condition of such subordination, Landlord
shall cause Lender (and all

                                       33
<PAGE>   41

future lenders) to execute a subordination and nondisturbance agreement (the
"SNDA") in substantially the form attached hereto as Exhibit "F" (or in such
other form as is mutually acceptable to Lender, Landlord and Tenant), and shall
cause Lender to deliver a fully executed counterpart to Tenant. The SNDA shall
contain provisions acceptable to Lender and Tenant covering rights and
obligations of Lender and Tenant in the event of a foreclosure of Landlord's
interest in the Project.

       (c) Tenant shall, in confirmation of the subordination set forth in
Section 20.01(6) and notwithstanding the fact that such subordination is
self-operative, and no further instrument or subordination shall be necessary,
within a reasonable period from receipt of written notice, at any time or times,
execute, acknowledge, and deliver to Landlord or to Lender reasonable
instruments mutually agreed upon by Landlord, Tenant and Lender to evidence such
subordination.

       (d) Tenant shall, upon reasonable request, at any time or times, execute,
acknowledge, and deliver to Lender and all future lenders, a subordination and
nondisturbance agreement in substantially the form attached hereto as Exhibit
"F." contingent upon Landlord's and Lender's simultaneous execution of same.

       (e) If Lender (or Lender's nominee, or other purchaser at foreclosure)
shall hereafter succeed to the rights of Landlord under this Lease, whether
through possession or foreclosure action or delivery of a new lease, Tenant
shall, if requested by such successor, attorn to and recognize such successor as
Tenant's landlord under this Lease without change in the terms and provisions of
this Lease, provided that such successor shall not be bound by any payment of
Base Rent for more than one month in advance, except prepayments in the nature
of security for the performance by Tenant of its obligations under this Lease,
and then only if such prepayments have been deposited with and are under the
control of such successor. Tenant shall promptly execute and deliver any
reasonable instrument that may be necessary to evidence such attornment.

       SECTION 20.02 ESTOPPEL. Tenant and Landlord agree, at any time, and from
time to time, within twenty (20) days after written request of the other, to
execute, acknowledge and deliver a statement in writing ("ESTOPPEL CERTIFICATE")
in recordable form to the other party and/or its designee in form and content
mutually satisfactory to Tenant, Lender and Landlord (or successor owner, if
any), certifying that: (i) if such should be the case, this Lease is unmodified
and in full force and effect (or, if there have been modifications, that the
same is in full force and effect, as modified if such be the case), (ii) the
dates to which Base Rent, and other charges have been paid, (iii) whether or
not, to the best knowledge of the signer of such certificate, there exists any
failure by the requesting party to perform any term, covenant or condition
contained in this Lease, and, if so, specifying each such failure of which the
signer may have knowledge, (iv) (if such be the case) Tenant has accepted the
Project and is conducting its business therein, and (v) as to such additional
matters as may be reasonably requested, and being in fact true, it being
intended that any such statement delivered pursuant hereto may be relied upon by
Landlord, Tenant and Tenant's successors and by any purchaser of title to the
Project or by any mortgagee or any assignee thereof or any party to any
sale-leaseback of the Project, or the landlord under a ground lease affecting
the Project.

       SECTION 21.01 DEFAULTS.

       (a) The occurrence of any one or more of the following events shall
constitute an "Event of Default" of Tenant under this Lease:

                  (i) if Tenant fails to pay Base Rent, Additional Rent or any
         other sum due hereunder as and when such rent or other sum becomes due
         and such failure shall continue for more than ten (10) days after
         receipt of written notice from Landlord of such failure;

                  (ii) if Tenant permits to be done anything which creates a
         lien upon the Project and fails to discharge such lien, bond such lien
         or post security with Landlord reasonably acceptable to Landlord within
         thirty (30) days after receipt by Tenant of written notice thereof;

                  (iii) if Tenant fails to maintain in force all policies of
         insurance required by this Lease and such failure shall continue for
         more than ten (10) days after Landlord gives Tenant written notice of
         such failure;

                  (iv) if any petition is filed by or against Tenant or
         Guarantor under any present or future section or chapter of the
         Bankruptcy Code, or under any similar law or statute of the United
         States or any state thereof (which, in the case of an involuntary
         proceeding, is not permanently discharged, dismissed, stayed, or
         vacated, as the case may be, within ninety (90) days of commencement),
         or if any order for relief shall be entered against Tenant or the
         Guarantor in any such proceedings;

                  (v) if Tenant or Guarantor becomes insolvent or makes a
         transfer in fraud of creditors or makes an assignment for the benefit
         of creditors;

                  (vi) if a receiver, custodian, or trustee is appointed for
         Tenant's interest in the Project or for all or substantially all of the
         assets of Tenant or Guarantor, which appointment is not vacated within
         ninety (90) days following the date of such appointment;

                  (vii) if Tenant fails to perform or observe any other term of
         this Lease and such failure shall continue for more than thirty (30)
         days after Landlord gives Tenant written notice of such failure, or, if
         such failure cannot be corrected within such thirty (30) day period, if
         Tenant does not commence to correct such default within said thirty
         (30) day period and thereafter diligently prosecute the correction of
         same to completion within a reasonable time;

                                       35
<PAGE>   43

                  (viii) if Guarantor fails to perform or observe any other
         term or provision of this Lease and such failure shall continue for
         more than thirty (30) days after Landlord gives Guarantor written
         notice of such failure, or, if such failure cannot be corrected within
         such thirty (30) day period, if Guarantor does not commence to correct
         such default within said thirty (30) day period and thereafter
         diligently prosecutes the correction of same to completion within a
         reasonable time;

                  (ix) if Tenant notifies Landlord in writing that it does not
         intend to occupy the Project and/or will not commence payment of Base
         Rent; or

                  (x) if Guarantor fails to execute the Intuit Guaranty
         simultaneously with the execution of this Lease, or if the Guarantor
         fails to perform or observe any term or provision of the Intuit
         Guaranty and such failure shall continue for more than thirty (30) days
         after Landlord gives Guarantor written notice of such failure, or, if
         such failure cannot be corrected within such thirty (30) day period, if
         Guarantor does not commence to cure such default within said thirty
         (30) day period and thereafter does not prosecute the correction of
         same to completion within a reasonable amount of time.

Landlord agrees that it shall accept a cure by the Guarantor of any default by
the Tenant hereunder prior to the date such default has become an Event of
Default.

       SECTION 21.02 REMEDIES.

       (a) Upon the occurrence of any one or more Events of Default, Landlord
may, at Landlord's option, without any demand or notice whatsoever (except as
expressly required in this Section 21.02):

                  (i) Continue this Lease in full force and effect, and Landlord
         shall have the right to collect Base Rent and other sums when due; or

                  (ii) Terminate Tenant's right to possession of the Project at
         any time by giving written notice to that effect, and relet the Project
         or any part thereof. On the giving of the notice, all of Tenant's
         rights in the Project shall terminate. Upon such termination, Tenant
         shall surrender and vacate the Project in good condition, ordinary wear
         and tear excepted, within sixty (60) days of the date of the notice,
         and Landlord may re-enter and take possession of the Project in
         accordance with applicable law. Any termination under this Section
         21.02 shall not release Tenant from the payment of any sum then due
         Landlord or from any claim for damages or Base Rent or other sum
         previously accrued or then accruing against Tenant. Upon such
         termination Tenant shall be liable immediately to Landlord for all
         reasonable costs Landlord incurs in reletting the Project or any part
         thereof, including, without limitation, broker's commissions, expenses
         of cleaning and reasonable costs and expenses for redecorating the
         Project required by the reletting, reasonable attorneys' fees actually
         incurred and like costs. Such costs shall be due and payable twenty
         (20) days after

                                       36
<PAGE>   44
         written demand for, and verification of, such costs are provided to
         Tenant. Reletting may be for a period shorter or longer than the
         remaining Term of this Lease. In the event such reletting is for a
         period longer than the remaining Term of this Lease, such costs shall
         be allocated based upon the ratio that the remaining Term of this Lease
         bears to the term of the reletting, unless such costs would not have
         been incurred but for Tenant's breach of the Lease. No act by Landlord
         other than giving express written notice of termination to Tenant shall
         terminate this Lease. Acts of maintenance, efforts to relet the Project
         permitted hereunder or the appointment of a receiver on Landlord's
         initiative to protect Landlord's interest under this Lease shall not
         constitute a termination of Tenant's right to possession. On
         termination, Landlord has the right, at Tenant's cost and without
         liability for the loss thereof or damage thereto, if Tenant has left
         any personal property or the Project, to remove all Tenant's personal
         property, which shall be deemed to have been abandoned by Tenant, and
         either store same or otherwise dispose of same in Landlord's sole and
         absolute discretion. Landlord and Tenant hereby acknowledge that in the
         event of such a termination, actual damages to Landlord may be
         difficult to ascertain and, accordingly, hereby agree that in such
         event, the net present value of the Base Rent due from the date of such
         termination to the expiration date of the Term or any extension, if
         exercised (the "EXPIRATION DATE"), discounted at five percent (5%) per
         annum, shall thereupon be due and payable to Landlord as liquidated
         damages within twenty (20) days after written notice therefor to
         compensate Landlord for Tenant's default and such termination. Such
         liquidated damages and costs shall be reduced (but not below zero) by
         the amount of rentals which Landlord has received at the time of
         payment by Tenant. In addition, Landlord shall reimburse Tenant (but
         not in excess of such liquidated damages and costs) the amount of
         rentals which Landlord receives as a result of its duty to mitigate set
         forth in subsection (f) of this Section 21.02 for the remaining Term of
         the Lease (without consideration of any renewal options), which payment
         by Landlord to Tenant shall be reduced by any reasonable costs, fees
         and expenses including brokerage commissions and refurbishment costs,
         incurred by Landlord in the exercise of its duty to mitigate
         hereunder)]. Rentals received by the Landlord after the aforesaid
         payments by Tenant (but not in excess of Tenant's payment of such
         liquidated damages and payment of Landlord's costs hereunder) for any
         period of time prior to the date that would have been the expiration
         date of this Lease had this Lease not been terminated, shall be
         immediately due and payable by Landlord to Tenant, and costs incurred
         by Landlord for reletting for a period longer than the remaining Term
         of this Lease shall be allocated as provided hereinabove, unless such
         costs would not have been incurred but for Tenant's breach of the
         Lease. Tenant waives redemption or relief from forfeiture under any
         other present or future law, in the event Tenant is evicted or Landlord
         takes possession of the Project by reason of any default of Tenant
         hereunder; or

                  (iii) Without terminating this Lease, and without terminating
         Tenant's obligation to pay all sums due and owing hereunder, including,
         without limitation, Base Rent and other sums due hereunder, in its own
         name but as agent for Tenant enter into and upon and take possession of
         the Project or any part thereof. Any property remaining in the Project
         may be removed and stored in a warehouse or elsewhere at the cost of,
         and for the account of Tenant

                                       37
<PAGE>   45
         without Landlord being deemed guilty of trespass or becoming liable for
         any loss or damage which may be occasioned thereby unless caused by
         Landlord's negligence. Thereafter, Landlord shall exercise commercially
         reasonable efforts to, in accordance with Section 21.02(f), lease to a
         third party the Project or any portion thereof as the agent of Tenant
         upon such terms and conditions as Landlord may deem necessary or
         desirable in order to relet the Project. The remainder of any rentals
         actually received by Landlord from such reletting, after the payment of
         any indebtedness due hereunder from Tenant to Landlord, and the payment
         of any costs and expenses of such reletting, shall be held by Landlord
         to the extent of and for application in payment of future rent owed by
         Tenant, if any, as the same may become due and payable hereunder. If
         such rentals received from such reletting shall at any time or from
         time to time be less than sufficient to pay to Landlord the entire sums
         then due from Tenant hereunder, Tenant shall pay any such deficiency to
         Landlord. Notwithstanding any such reletting without termination,
         Landlord may at any time thereafter elect to terminate this Lease for
         any such previous default provided same has not been cured; or

                  (iv) Without terminating this Lease, and with or without
         notice to Tenant, enter into and upon the Project and without being
         liable for prosecution or any claim for damages therefor, maintain the
         Project and repair or replace any damage thereto or do anything or make
         any payment for which Tenant is responsible hereunder. Tenant shall
         reimburse Landlord immediately upon demand for any expenses which
         Landlord incurs in thus effecting Tenant's compliance under this Lease
         and Landlord shall not be liable to Tenant for any damages with respect
         thereto.

                  (v) Without liability to Tenant or any other party and without
         constituting a constructive or actual eviction, suspend or discontinue
         furnishing or rendering to Tenant any property, material, labor,
         utilities or other service, wherever Landlord is obligated to furnish
         or render the same so long as Tenant is in default under this Lease; or

                  (vi) Without terminating this Lease, immediately cease all
         construction work required to be performed by Landlord pursuant to the
         terms of this Lease and/or allow the Project to remain unoccupied and
         /or incomplete until the Event of Default is cured to the reasonable
         satisfaction of Landlord (which right to cure such Event of Default is
         subject to the consent of Landlord, which consent shall not be
         unreasonably withheld), and collect rent from Tenant as it comes due
         (for purposes of this provision, Base Rent shall commence on the date
         which Tenant commits an Event of Default); or

                  (vii) Fulfill any obligation of Tenant under this Lease,
         including, without limitation, the payment of insurance premiums or
         obtaining insurance policies required under this Lease, and Tenant
         shall reimburse Landlord upon demand for all costs, expenses and/or
         premiums paid by Landlord; or

                  (viii) Pursue such other remedies as are available at law or
         in equity.

                                       38

<PAGE>   46

       (b) If this Lease shall terminate as a result of or while there exists an
Event of Default hereunder, any funds of Tenant held by Landlord may be applied
by Landlord to any damages payable by Tenant (whether provided for herein or by
law) as a result of such termination or default.

       (c) Neither the commencement of any action or proceeding, nor the
settlement thereof, nor entry of judgment thereon shall bar Landlord from
bringing subsequent actions or proceedings from time to time, nor shall the
failure to include in any action or proceeding any sum or sums then due be a bar
to the maintenance of any subsequent actions or proceedings for the recovery of
such sum or sums so omitted.

       (d) No agreement to accept a surrender of the Project and no act or
omission by Landlord or Landlord's agents during the Term shall constitute an
acceptance or surrender of the Project unless made in writing and signed by
Landlord. No re-entry or taking possession of the Project by Landlord pursuant
to this Section 21.02 shall constitute an election by Landlord to terminate this
Lease unless a written notice of such intention is given to Tenant. Landlord's
acceptance of Base Rent or other sums in full or in part following an Event of
Default hereunder shall not be construed as a waiver of such Event of Default.
No custom or practice which may come to exist between the parties in connection
with the terms of this Lease shall be construed to waive or lessen either
party's right to insist upon strict performance of the terms of this Lease,
without a written notice thereof to the other party.

       (e) If an Event of Default shall occur, Tenant shall pay to Landlord, on
demand, all expenses incurred by Landlord as a result thereof, including
reasonable attorneys' fees, court costs and expenses actually incurred.

       (f) Landlord's and Tenant's rights pursuant to this Section 21.02,
including, without limitation, Landlord's rights to collect Base Rent and other
charges due under this Lease, shall survive any termination of this Lease.
Notwithstanding anything to the contrary contained herein, Landlord and Tenant
hereby agree that Landlord shall have a duty to reasonably mitigate or attempt
to offset any damages which are or may be suffered by Landlord as a result of
any default of Tenant under this Lease in accordance with and to the extent
required by Texas law. Any payment by Tenant of a sum of money less than the
entire amount due Landlord at the time of such payment shall be applied to the
obligations that are then furthest in arrears. No endorsement or statement on
any check or accompanying any payment shall be deemed an accord and satisfaction
and any payment accepted by Landlord shall be without prejudice to Landlord's
right to obtain the balance due or pursue any other remedy available to Landlord
both in law and in equity.

        (g) Upon occurrence of an uncured Event of Default, Tenant's rights to
 sublease or assign under Section 19.01 of this Lease shall immediately
 terminate.
                                       39
<PAGE>   47

       (h) Notwithstanding anything contained herein to the contrary, upon the
occurrence of an Event of Default, Landlord shall not have the right to
dispossess Tenant from the Project without judicial process and Landlord shall
specifically have no right of commercial lock-out without the benefit of
judicial review.

       SECTION 21.03 LANDLORD'S DEFAULT.

                  (a) (i) If prior to Substantial Completion, and as an
         alternative to recourse under the Completion Guaranty, Landlord
         defaults in the performance or observance of any provision of this
         Lease or the Covenants (including, but not limited to, the failure to
         deliver to Tenant an executed original of the Completion Guaranty),
         Tenant may, at its option, give Landlord and Lender written notice
         specifying in what manner Landlord has defaulted, provided that
         Tenant's failure, if any, to give such notice shall not be deemed to be
         a waiver by Tenant of such default. If such default shall not have been
         cured by Landlord or its Lender within thirty (30) days after the
         receipt of such notice (except that if such default cannot be cured
         within said thirty (30) day period, this period shall be extended for a
         reasonable additional time provided that Landlord or its Lender
         commences to cure such default within the thirty (30) day period and
         diligently proceeds to effect such cure), Tenant may cure such default
         and Landlord shall reimburse Tenant within twenty (20) days after
         receipt of a certified invoice from Tenant accompanied by applicable
         bills for any reasonable amount paid and any reasonable expense or
         contractual liability incurred with interest at the Specified Rate
         accruing from the date of payment by Tenant to the date of
         reimbursement by Landlord; provided, however, Tenant hereby expressly
         waives any right to claim or collect consequential or punitive damages
         therefor and waives all other remedies except for those specifically
         made available in this Section 21.03 to Tenant for the respective
         default by Landlord. If Landlord fails to reimburse Tenant within the
         time period specified herein, Tenant may offset the amounts required to
         be reimbursed against the next following payments of Base Rent and/or
         Additional Rent, plus interest at the Specified Rate accrued to the
         date of offset, against subsequent payments of Base Rent and/or
         Additional Rent until such amounts have been reimbursed in full;
         provided, however, such offset shall be limited to 25% of the Base Rent
         and/or Additional Rent due and payable each month throughout the then
         existing Term of this Lease, but in the event such percentage
         limitation will not enable Tenant to be fully reimbursed prior to the
         expiration of the then existing Term of this Lease, then the amount
         required to be reimbursed shall be divided by the number of months
         remaining in the then existing Term of this Lease, and the quotient
         thereof, plus accrued interest at the Specified Rate shall be offset
         against the monthly payments of Base Rent and/or Additional Rent over
         the remainder of the then existing Term of this Lease.

                  (ii) The foregoing provisions to the contrary notwithstanding,
         in the event that subsequent to Substantial Completion, Landlord
         defaults in the performance or observance of any provision of this
         lease, beyond any applicable cure period, tenant may cure such default
         and Landlord shall reimburse Tenant within thirty (30) days after
         receipt of a certified invoice from Tenant accompanied by applicable
         bills for any reasonable amount paid and any reasonable expense or
         contractual liability incurred, with interest at the Specified Rate
         accruing from the date of payment by Tenant to the date of
         reimbursement by Landlord and if Landlord fails to reimburse

                                       40

<PAGE>   48
         Tenant within such time period, Tenant may offset the amounts required
         to be reimbursed, plus interest at the Specified Rate accrued to the
         date of offset, against subsequent payments of Base Rent and/or
         Additional Rent until such amounts have been reimbursed in full;
         provided, however, such offset shall be limited to 25% of the Base Rent
         and/or Additional Rent due and payable each month throughout the then
         existing Term of this Lease, but in the event such percentage
         limitation will not enable Tenant to be fully reimbursed prior to the
         expiration of the then existing Term of this Lease as of the date the
         reimbursement is due and payable, then the amount required to be
         reimbursed shall be divided by the number of months remaining in the
         then existing Term of this Lease, and the quotient thereof, plus
         accrued interest at the Specified Rate shall be offset against the
         monthly payments of Base Rent and/or Additional Rent over the remainder
         of the then existing Term of this Lease. In the event that Tenant
         determines, in the exercise of its good faith reasonable judgment, that
         the remedy of self help and offset is either unavailable or inadequate,
         then Tenant may institute a proceeding for specific performance against
         Landlord and/or for a declaratory judgment with the appropriate legal
         or equitable remedies, and in the event that Tenant determines, again
         in the exercise of its good faith reasonable judgment, that the remedy
         of specific performance and/or declaratory judgment is either
         unavailable or inadequate, Tenant may plead in the alternative for
         actual damages (and Tenant hereby expressly waives any right to claim
         or collect consequential or punitive damages), which damages shall be
         limited to the lesser of Landlord's equity in the Project or the sum of
         $5,000,000.00.

        (b) Except as otherwise provided in Section 21.03(c) and (d), and in
addition to recourse under the Completion Guaranty, in the event of Landlord's
failure to achieve Substantial Completion by the date set forth in the
Development Schedule, as may be extended by Force Majeure and Tenant Delays,
Landlord shall be obligated, as liquidated damages and Tenant's sole and
exclusive remedy for such delay, to pay to Tenant the sum of Eight Thousand and
No/100 Dollars ($8,000.00) for each day that the Landlord fails to achieve
Substantial Completion, until the date Landlord achieves Substantial Completion.
At Landlord's election, such liquidated damage sum may be paid to Tenant in the
form of a rental credit upon the commencement of payment of Base Rent. The
parties acknowledge and agree that the damages that the Tenant will incur in
such event are difficult to determine or ascertain with certainty as of the time
of the signing of this Lease and that the amount of liquidated damages provided
for herein is not intended as a penalty but, instead, represents their best
reasonable estimate, based on the information available to them, of the damages
that would be incurred and which shall be payable by Landlord in that event to
compensate Tenant as damages resulting from such event.

        (c) In lieu of the remedies set forth in Section 21.03(a)(i) and (b), as
an alternative to recourse under the Completion Guaranty, in the event that the
Landlord fails to complete the following elements of the Project in accordance
with the dates set forth below, subject to Force Majeure and Tenant Delays, the
Tenant may, at Tenant's sole discretion and upon thirty (30) days prior written
notice to Landlord and as its sole and exclusive remedy (except as provided in
subsection (v) below), terminate this Lease in which event neither Tenant nor
Landlord shall have any further obligation hereunder, one to the other:

                                       41
<PAGE>   49

                  (i) Landlord fails to deliver to Tenant an executed original
         of the Completion Guaranty within fifteen (15) days of the date of this
         Lease;

                  (ii) Landlord's failure to acquire title to the Phase I
         Property (subject only to the Permitted Exceptions and such other
         exceptions permitted by Section 1.01(b)) on or before the date which is
         ninety (90) days following the date set forth for such event in the
         Development Schedule;

                  (iii) Landlord fails to commence the site work for the Project
         on or before the date which is one hundred fifty (150) days following
         the date set forth for such event in the Development Schedule;

                  (iv) Landlord fails to complete the "dry-in" of the Building
         on or before the date which is one hundred fifty (150) days following
         the date set forth for such event in the Development Schedule; or

                  (v) Landlord fails to achieve Substantial Completion within
         one hundred fifty (150) days following the date set forth for such
         event in the Development Schedule, in which event Tenant shall also be
         entitled to exercise the remedy in Section 21.03(d) below.

        (d) In the event that the Landlord fails to achieve Substantial
Completion within one hundred fifty (150) days following the date set forth for
such event in the Development Schedule, subject to Force Majeure and Tenant
Delays, provided the Lease has then been terminated pursuant to subsection (c)
above, Landlord shall pay to Tenant as liquidated damages the amount of Five
Hundred Thousand and No/100 Dollars ($500,000.00) to compensate Tenant for
damages it will incur due to Landlord's failure to timely complete the Project.
The parties acknowledge and agree that the damages that the Tenant will incur in
such event are difficult to determine or ascertain with certainty as of the time
of the signing of this Lease and that the amount of liquidated damages provided
for herein is not intended as a penalty but, instead, represents their best
reasonable estimate, based on the information available to them, of the damages
that would be incurred and which shall be payable by Landlord in that event to
compensate Tenant as damages resulting from such event.

        SECTION 21.04 WAIVER. The waiver by either party of any default of the
failure to insist upon strict compliance with any provision hereof, shall not be
deemed to be a waiver of any subsequent default under the same, or under any
other term, covenant or condition of this Lease. The subsequent acceptance of
any rent by Landlord shall not be deemed to be a waiver of any preceding default
by Tenant under any term, covenant or condition of this Lease, other than the
failure of Tenant to pay the particular rent so accepted, regardless of
Landlord's knowledge of such preceding default at the time of acceptance of such
Rent.

                       ARTICLE 24 - ENVIRONMENTAL MATTERS

         SECTION 24.01 HAZARDOUS SUBSTANCES CONTAMINATION.

        (a) For purposes of this Lease:

                  (i) "CONTAMINATION" as used herein means the uncontained or
         uncontrolled presence of or release of Hazardous Substances (as
         hereinafter defined) into any environmental media from, upon, within,
         below, into or on any portion of the Project or the Building, so as to
         require remediation, cleanup or investigation under any applicable
         Environmental Law (as hereinafter defined).

                  (ii) "ENVIRONMENTAL LAWS" as used herein means all federal,
         state, and local laws, regulations, orders, permits, ordinances or
         other requirements, concerning protection of human health, safety and
         the environment, all as may be amended from time to time.

                  (iii) "HAZARDOUS SUBSTANCES" as used herein means any
         hazardous or toxic substance, material, chemical, pollutant,
         contaminant or waste as those terms are defined by any applicable
         Environmental Laws [including, without limitation, the Comprehensive
         Environmental Response, Compensation and Liability Act, 42 U.S.C. 9601
         et seq. ("CERCLA") and the Resource Conservation and Recovery Act, 42
         U.S.C. 6901 et seq. ("RCRA")] and any solid wastes, polychlorinated
         biphenyls, urea formaldehyde, asbestos, radioactive materials, radon,
         explosives, petroleum products and oil.

        (b) Landlord represents and covenants that Landlord has not treated,
stored or disposed of any Hazardous Substances upon or within the Project, nor
shall Hazardous Substances be used in connection with the construction of the
Building (except as normally utilized in construction of similar projects), nor,
to Landlord's current, actual knowledge, has any predecessor owner of the
Project stored, treated or disposed of Hazardous Substances upon or within the
Project. Landlord's

                                       44
<PAGE>   52

investigation and knowledge with respect to the environmental condition of the
Real Property shall be limited to the content of that certain Phase I
Environmental Report No. 94007041 A dated January 27, 2000 and prepared by HBC
Engineering, Inc.

        (c) Tenant represents and covenants that all its activities on the
Project and the Building, during the course of this Lease will be conducted in
compliance with Environmental Laws. Tenant warrants to the best of Tenant's
actual knowledge that it is currently in compliance with all applicable
Environmental Laws and that there are no pending or threatened notices of
deficiency, notices of violation, orders, or judicial or administrative actions
involving alleged violations by Tenant of any Environmental Laws. Tenant, at
Tenant's sole cost and expense, shall be responsible for obtaining all permits
or licenses or approvals under Environmental Laws necessary for Tenant's
operation of its business on the Project and shall make all notifications and
registrations required by any applicable Environmental Laws. Tenant, at Tenant's
sole cost and expense, shall at all times comply with the terms and conditions
of all such permits, licenses, approvals, notifications and registrations and
with any other applicable Environmental Laws. Tenant covenants that it will
obtain all such permits, licenses or approvals and make all such notifications
and registrations required by any applicable Environmental Laws necessary for
Tenant's operation of its business on the Project. Tenant shall not, however, be
required to obtain any permits, licenses, approvals, notifications or
registrations related to the construction of the Building.

        (d) Tenant shall not cause or permit any Hazardous Substances to be
brought upon, kept or used in or about the Project or the Building, without the
prior written consent of Landlord, which consent shall not be unreasonably
withheld; provided, however, that the consent of Landlord shall not be required
for the use at the Project of cleaning supplies, toner for photocopying machines
and other similar materials, as well as other substances typically used in
Tenant's business that might otherwise be considered Hazardous Substances, in
containers and quantities reasonably necessary for and consistent with normal
and ordinary use by Tenant, at the Project, in the routine operation of Tenant's
business or maintenance of Tenant's office or in the routine janitorial service,
cleaning and maintenance for the Project. For purposes of this Section 24.01,
Landlord shall be deemed to have reasonably withheld consent if Landlord
determines that the presence of such Hazardous Substance within the Project
could result in a risk of harm to person or property or otherwise negatively
affect the value or marketability of the Building or the Project.

        (e) Tenant shall not cause or permit the release of any Hazardous
Substances by Tenant or its agents, contractors, employees or invitees into any
environmental media such as air, water or land, or into or on the Project or the
Building in any manner that violates any Environmental Laws. If such release
shall occur, Tenant shall (i) take all steps reasonably necessary to contain and
control such release and any associated Contamination, (ii) clean up or
otherwise remedy such release and any associated Contamination to the extent
required by, and take any and all other actions required under, applicable
Environmental Laws and (iii) notify and keep Landlord reasonably informed in
writing of such release and response.

                                       45
<PAGE>   53

        (f) Regardless of any consents granted by Landlord pursuant to Section
24.01 (d) allowing Hazardous Substances upon the Project, Tenant shall under no
circumstances whatsoever (i) cause or permit any activity on the Project which
would cause the Project to become subject to regulation as a hazardous waste
treatment, storage or disposal facility under RCRA or the regulations
promulgated thereunder; (ii) discharge Hazardous Substances into the storm sewer
system serving the Project; or (iii) install any underground storage tank or
underground piping under the Project.

        (g) Tenant shall and hereby does indemnify, defend and hold Landlord
harmless from and against any and all expense, loss and liability suffered by
Landlord (with the exception of those expenses, losses, and liabilities arising
from Landlord's own negligence or willful act), by reason of Tenant's improper
storage, generation, handling, treatment, transportation, disposal, or
arrangement for transportation or disposal, of any Hazardous Substances caused
or permitted by Tenant to be brought upon the Project (whether accidental,
intentional, or negligent) or by reason of Tenant's breach of any of the
provisions of this Section 24.01. Such expenses, losses and liabilities shall
include, without limitation, (i) any and all expenses that Landlord may incur to
comply with any Environmental Laws as a result of Tenant's failure to comply
therewith; (ii) any and all costs that Landlord may incur in studying or
remedying any Contamination at or arising from the Project or the Building;
(iii) any and all costs that Landlord may incur in studying, removing, disposing
or otherwise addressing any Hazardous Substances; (iv) any and all fines,
penalties or other sanctions assessed upon Landlord by reason of Tenant's
failure to comply with Environmental Laws; and (v) any and all legal and
professional fees and costs incurred by Landlord in connection with the
foregoing. The indemnity contained herein shall survive the termination or
expiration of this Lease.

        (h) Landlord shall have the right, but not the obligation, upon
twenty-four (24) hours prior written notice and during normal business hours,
except for emergencies, to enter the Project accompanied by Tenant's
representative throughout the Term to audit and inspect the Project for Tenant's
compliance with this Section 24.01.

        (i) Landlord shall and hereby does indemnify, defend and hold Tenant
harmless from and against any and all expenses, loss and liability suffered by
Tenant (with the exception of those expenses, losses and liabilities arising
from Tenant's own negligence or willful act or the negligence or willful act of
Tenant's officers, contractors, licensees, agents, servants, guests, invitees or
visitors) by reason of the presence of any Hazardous Substances in the Building
or on or under the Project at any time prior to the Term Commencement Date, or
placed or caused to be placed by Landlord, its agents or employees in, on or
under the Project thereafter.

                         ARTICLE 25 - PROJECT EXPANSIONS

        SECTION 25.01 EXPANSION NOTICE. The Tenant shall have the right to cause
the development of one or more Project Expansions by satisfying the provisions
of this Article 25. Likewise, the Tenant reserves the right to cause Landlord to
acquire one or more portions of the Future Development Property and to construct
Project Expansions in the event that the Tenant provides written notices (an
"EXPANSION NOTICE") TO THE Landlord on or before September 30, 2005 (or such

                                       46
<PAGE>   54

earlier date which is two hundred seventy (270) days prior to the outside option
closing date set forth in the Acquisition Contract), which notices shall contain
substantially the same specificity of detail for the Project Expansion as is
described for Phase I of the Project in the Base Building Outline Specifications
attached hereto as Exhibit "C" (including, but not limited to, any surface
parking or parking structures required by Tenant), modified to reflect the
features and square footage of the Project Expansion. An Expansion Notice shall
also contain a proposed development timeline (the "EXPANSION DEVELOPMENT
TIMELINE") requested by Tenant in connection with the development of the Project
Expansion, which Expansion Development Timeline shall consist of dates for the
development of plans and specifications, acquisition of the portion of the Real
Property applicable to the Project Expansion, commencement of the construction
of the Project Expansion and the date for Substantial Completion of the Project
Expansion. In addition, the Expansion Notice shall identify with specificity the
portion of the Real Property upon which the Project Expansion shall be
developed, subject to the provisions of the Acquisition Contract. Subject to the
provisions of this Article 25, Landlord shall acquire the portion of the Future
Development Property outlined in the Expansion Notice on or before the date set
forth in the Expansion Development Schedule (as approved by Landlord and Tenant
as provided in Section 25.02) for the acquisition of the Future Development
Property and in accordance with the terms of the Acquisition Contract.

        SECTION 25.02 SPECIFICATION NOTICE. Within sixty (60) days following
receipt of an Expansion Notice, Landlord shall submit to Tenant a notice (the
"SPECIFICATION NOTICE"), which notice shall contain preliminary conceptual plans
and specifications for the Project Expansion (the "Outline Specifications"), as
well as (i) Landlord's best good faith estimate of total costs (hard and soft)
of constructing the Project Expansion, (ii) the projected Base Rent, based on
the prevailing interest rates at the date of the Specification Notice, and (iii)
a development schedule consisting of dates for the development of plans and
specifications, acquisition of the portion of the Real Property applicable to
the Project Expansion, commencement of the construction of the Project Expansion
and the date for Substantial Completion of the Project Expansion (the "EXPANSION
DEVELOPMENT SCHEDULE"), all of which shall be mutually reviewed and approved by
Landlord and Tenant within thirty (30) days following receipt of the
Specification Notice. During such thirty (30) days, Landlord and Tenant agree to
act reasonably and in good faith to reconcile any differences between the
Expansion Notice and the Specification Notice in order to avoid any delay in the
commencement of the Project Expansion.

        SECTION 25.03 GOVERNING PROVISIONS. In the event that the Tenant timely
exercises its rights to cause the development of a Project Expansion, the
following provisions shall control the development thereof:

        (a) Tenant acknowledges that each Project Expansion must satisfy the
provisions of the Acquisition Contract with respect to the notices required to
be given and timing of any closings to occur thereunder and the configuration of
the portion of the Future Development Property to be acquired by Landlord in
connection with the Project Expansion described in the Expansion Notice.

                                       47
<PAGE>   55

The Landlord shall not be bound to develop the Project Expansion described in
the Expansion Notice unless the provisions of such Expansion Notice expressly
satisfy the terms, provisions and conditions of the Acquisition Contract related
thereto.

        (b) The building and other improvements to be constructed pursuant to
each Project Expansion shall be of a design, nature and type substantially
similar to the Building, unless at the request of Tenant, Landlord, in its sole,
reasonable discretion, shall agree to construct a Project Expansion of a
different design, nature and type. Notwithstanding anything herein to the
contrary, the Tenant Improvements may be of a different design, nature and type
but if the cost of such Tenant Improvements exceeds $30.00 per square foot,
Tenant shall pay such excess cost.

        (c) Base Rent for each Project Expansion calculated as provided herein
below, shall commence upon the date that each Project Expansion is Substantially
Completed, subject only to "punch list" items and other items of incomplete work
that do not materially adversely interfere with the use and occupancy of the
Project Expansion (as certified to Landlord and Tenant by the Architect) and
delivered to Tenant for Tenant's occupancy (the "PROJECT EXPANSION COMMENCEMENT
DATE"). Each Project Expansion Base Rent shall be included in the definition of
"Base Rent" for purposes of this Lease, and shall be payable concurrently with
payments of Base Rent hereunder as set forth in Section 5.01 of this Lease. Upon
the acquisition of any portion of the Future Development Property, each Project
Expansion shall be deemed to be a part of the Project hereunder, and, upon the
Project Expansion Commencement Date, in addition to Base Rent, Tenant shall pay
all Additional Rent for each Project Expansion as set forth in the Lease.

        (d) Annual Base Rent for each Project Expansion shall be equal to the
amount obtained by multiplying (i) one hundred percent (100%) of the costs
(including both so-called "hard costs" and "soft costs" and land acquisition
costs) incurred by Landlord to construct the Project Expansion (which costs
shall be subject to Tenant's reasonable right of audit and review) by (ii) an
interest rate equal to four hundred (400) basis points in excess of the interest
rate payable for the most recently issued 10-year treasury obligations of the
United States government as of each Project Expansion Commencement Date (as
reported in The Wall Street Journal or its successor publication). Base Rent for
each Project Expansion shall increase over the Term in an amount corresponding
to the percentage increase of Base Rent for the Project Expansion for each Lease
Period, as described in Section 5.01 and in the expansion phases of Exhibit "H,"
or for each Renewal Term, as described in Section 4.02 and the expansion phases
of Exhibit "H."

        (e) This Lease shall be modified such that the Term of the Lease for the
Project (including each prior Project Expansion, if any) shall expire ten (10)
years from the last of any Project Expansion Commencement Dates.

        (f) Anything in this Article 25 to the contrary notwithstanding,
Landlord shall be obligated to construct any Project Expansion and lease the
Project Expansion to Tenant only if the following conditions shall be satisfied:

                                       48
<PAGE>   56

                  (i) No uncured Event of Default shall exist:

                  (ii) This Lease shall not have been terminated and shall be in
         full force and effect; and

                  (iii) Either (1) Guarantor consents to such Project Expansion
         and agrees that the Guarantor shall guarantee the obligations of the
         Tenant with respect to the Project Expansion, or (2) Lacerte (if
         Lacerte is not then the Tenant under this Lease) or Tenant shall have a
         tangible net worth calculated in accordance with generally accepted
         accounting principles at the time of delivery of such Expansion Notice
         equal to or greater than One Hundred Million and No/100 Dollars U.S.
         ($100,000,000.00 U.S.), and Tenant agrees that the Base Rent payable
         with respect to such Project Expansion shall equal the calculation
         provided for Base Rent in Section 25.03(d), except that the reference
         therein to four hundred (400) basis points shall become five hundred
         fifty (550) basis points. Failure of Guarantor to consent to any
         Project Expansion shall not relieve Guarantor of any other liability
         under the Intuit Guaranty.

         (g) Except as provided otherwise in this Article 25, each and every
right, duty, obligation, agreement and remedy of the Landlord and of the Tenant
respectively, under this Lease Agreement with respect to the development and
construction of Phase I of the Project shall be equally applicable and binding
on the respective parties with respect to the development and construction of
each Project Expansion, it being understood that the Base Building Outline
Specifications and Site Plans for the Project Expansion and the Expansion
Development Schedule for each Project Expansion shall be attached hereto as
additional and consecutively lettered exhibits and dated and signed by the
Landlord and Tenant promptly after approval thereof by Landlord and Tenant. Each
such set of exhibits shall further identify each Project Expansion numerically
in the order in which they occurred. In addition, all the terms, provisions and
conditions of this Lease shall govern the rights and liabilities of Landlord and
of Tenant with respect to any Project Expansion, including, but not limited to,
the provisions relating to the commencement and payment of Base Rent and
Additional Rent, the providing of the Improvement Allowance at Thirty and No/100
Dollars ($30.00) per square foot of Rentable Area of the Project Expansion as
provided in Section 3.02 hereof, Landlord and Tenant repair and replacement
obligations, remedies upon an Event of Default and payments owed to Brokers.
When the portion of the Future Development Property for each Project Expansion
is acquired in accordance with terms hereof, then such Project Expansion shall
be deemed to be part of the Project for purposes of this Lease.

         (h) In the event that Landlord has sold the Project and it is no longer
the Landlord hereunder, the Tenant may cause a Project Expansion to be developed
by the successor landlord (the "SUCCESSOR LANDLORD"). If the Successor Landlord
elects not to be the developer of the Project Expansion, the Successor Landlord
shall identify in the Specification Notice the proposed developer for the
Project Expansion, the use of which proposed developer shall be subject to the
Tenant's

                                       49
<PAGE>   57

reasonable prior right of approval, which reasonable approval shall not be
unreasonably withheld. Each and every obligation of the Landlord with respect to
the development and construction of a Project Expansion shall be applicable to
and binding upon the Successor Landlord.

         (i) Any reference in any part of this Article 25 to specific sections
or terms of this Lease Agreement is not intended to imply or infer that the
other sections or terms of this Lease Agreement are inapplicable to any Project
Expansion, it being agreed instead that all sections and terms of this Lease
Agreement shall apply equally to any Project Expansion, except as modified in
this Article 25. Landlord and Tenant agree that the terms of Section 2.05
regarding the guarantee of the construction obligations by Koll, the terms of
Section 3.04 regarding "Supplemental Allowance" and the terms of Section 4.03
regarding "Refurbishment Allowance" shall not apply to any Project Expansion.

Agreement shall have the following meanings in the context of an Article 25
Project Expansion for which an Expansion Notice has been given by Tenant:

                  (i) The term "Phase I" shall, whenever the context so requires

         Development Schedule provided for in Section 25.02 hereof for the
         development and construction of the Project Expansion;

                  (iv) The term "Building" shall mean the structure and related
         improvements being constructed by the Landlord or Successor Landlord
         for the Project Expansion;

                  (v) The term "Parking" shall mean the number and types of
         parking spaces to be provided for the Project Expansion, to be
         configured and of the type and amount to accommodate the capacity of

         the term "TI Contractor" shall mean the contractor proposed and/or used
         by Tenant for construction of the Tenant Improvements for the Project
         Expansion;

                  (ix) The term "Base Building Work" shall mean the scope of the

                           (1) Landlord or Successor Landlord fails to acquire
                  title to the Future Development Property (subject only to the
                  Permitted Exceptions and such other exceptions permitted by

<PAGE>   59

                  (ii) As an alternative remedy to subsection (j)(i) above, in
         the event of Landlord's or Successor Landlord's failure to achieve
         Substantial Completion by the date set forth in the Expansion
         Development Schedule, as that date may be extended by Force Majeure and
         Tenant Delays, Landlord shall be obligated, as liquidated damages for
         such delay, to pay to Tenant the sum of Eight Thousand and No/100
         Dollars ($8,000.00) for each day that the Landlord fails to achieve
         Substantial Completion, until the date Landlord achieves Substantial
         Completion. At Landlord's election, such liquidated damage sum may be
         paid to Tenant in the form of a rental credit upon the commencement of
         payment of Base Rent for the Project Expansion. The parties acknowledge
         and agree that the damages that the Tenant will incur in such event are
         difficult to determine or ascertain with certainty as of the time of
         the signing of this Lease and that the amount of liquidated damages
         provided for herein is not intended as a penalty but, instead,
         represents their best reasonable estimate, based on the information
         available to them, of the damages that would be incurred and which
         shall be payable by Landlord in that event to compensate Tenant as
         damages resulting from such event.

                  (iii) As an additional remedy in the event of a termination
         under subsection (j)(i)(aa) above, in the event that the Landlord or
         Successor. Landlord fails to achieve Substantial Completion within one
         hundred fifty (150) days following the date set forth for such event in
         the Expansion Development Schedule, subject to Force Majeure and Tenant
         Delays, in the event Tenant has exercised its right to terminate the
         Lease as to Project Expansion only as described in subsection (j)(i)
         (aa) above, Landlord shall pay Tenant as liquidated damages the amount
         of Five Hundred Thousand and No/100 Dollars ($500,000.00) to compensate
         Tenant for damages it will incur due to Landlord's or Successor
         Landlord's failure to timely complete the Project Expansion. The
         parties acknowledge and agree that the damages that the Tenant will
         incur in such event are difficult to determine or ascertain with
         certainty as of the time of the signing of this Lease and that the
         amount of liquidated damages provided for herein is not intended as a
         penalty but, instead, represents their best reasonable estimate, based
         on the information available to them, of the damages that would be
         incurred and which shall be payable by Landlord in that event to
         compensate Tenant as damages resulting from such event.

                  (iv) In the event there are recorded against the Future
         Development Property any easements or exceptions which arise or exist
         as a result of the acts, omissions or participation, directly or
         indirectly, of Landlord (other than the Permitted Exceptions and other
         than those easements and exceptions which are necessary in connection
         with the development of the Project, provided such additional easements
         and exceptions do not impair Tenant's use of the Project, in which
         event the remedies provided in this subsection (iv) shall not apply),
         (1) the Tenant may, prior to the commencement of construction of the
         Project Expansion and upon thirty (30) days prior written notice to
         Landlord either terminate this Lease as to the Project Expansion only,
         in which event neither Tenant nor Landlord shall

                                       52
<PAGE>   60

         have any further obligation hereunder as to the Project Expansion only,
         one to the other, or (2) the Tenant may seek the remedies provided in
         Section 21.03(a)(ii) (notwithstanding that such remedies as to Phase I
         are applicable only after Substantial Completion).

                  (v) In the event there are recorded against the Future
         Development Property any easements or exceptions which do not arise or
         exist as a result of the acts, omissions or participation, directly or
         indirectly, of Landlord (other than the Permitted Exceptions and other
         than those easements and exceptions which are necessary in connection
         with the development of the Project, provided such additional easements
         and exceptions do not impair Tenant's use of the Project, in which
         event the remedies provided in this subsection (v) shall not apply),
         (1) the Tenant may, prior to the commencement of construction of the
         Project Expansion and upon thirty (30) days prior written notice to
         Landlord either terminate this Lease as to the Project Expansion only,
         in which event neither Tenant nor Landlord shall have any further
         obligation hereunder as to the Project Expansion only, one to the
         other, and/or (2) Tenant may request Landlord to, and Landlord shall,
         use commercially reasonable efforts to remove such easements or
         exceptions, and/or (3) Tenant may request Landlord to, and Landlord
         shall, assign to Tenant those contractual rights and claims held by
         Landlord pertaining to such easements or exceptions, and Tenant may
         contest the same at its sole cost and expense.

<PAGE>   61

         (e) No failure of Landlord or Tenant to exercise any power given
Landlord or Tenant hereunder or to insist upon strict compliance by Landlord or

Tenant's rights to demand exact compliance with the terms hereof.

either party unless such waiver is in writing and signed by the party making

terms or provisions of this Lease or the scope or intent thereof.

shall constitute an original, but all of which taken together shall constitute

                                LACERTE SOFTWARE

             CLARIFICATIONS TO BASE BUILDING OUTLINE SPECIFICATIONS

The following clarifications apply to the Request for Proposal issued by The
Staubach Company for the Lacerte Software project. In the event of conflict
between Exhibit A of the Request for Proposal and these clarifications, the
information included in the clarifications below shall apply.

1)  The requirement for parking lighting levels is clarified to be 2 fc average,
    on a maintained basis, and shall include "Medium Activity Level" lighting
    for parking structures, per IES standards.

2)  Dual feed electrical service is not included at this time. Koll will assist
    Lacerte in securing this requirement, based on the final site selection.
    Lacerte will evaluate the cost impact for acceptance at that time.

3)  Offsite turn lanes, median cuts, or utilities extensions are included for
    the site located at the Northeast corner of Parkwood and Headquarters in
    Legacy Business Park, Plano, Texas.

4)  Main Lobby finishes are included in the shell building, based on one Main
    Lobby area of approximately 2,000 - 2,500 s.f. and assuming that Main Lobby
    floor coverings are approximately 50% hard surface and 50% carpet. All
    carpeting, including Main Lobby, shall be included as part of the T.I.
    allowance.

5)  Full wet pipe fire protection system is included in the shell building,
    including the installation of heads on a floor with no partitions in place
    other than core partitions. Installation of heads will be coordinated with
    final TI plans to minimize cost. However, increased headcount due to TI
    plans, or relocations due to changes during TI buildout, will be a cost of
    the TI allowance.

6)  Tenant Power and Lighting Distribution: Koll has included dual 84 pole
    electrical panels (one clean and one dirty) at each electrical room for
    power distribution. It is anticipated that the building layout will include
    one electrical room for each floor of each "Pod" serving approx. 25,000 to
    30,000 sf. Therefore, a total of twelve (12) panels for tenant power
    distribution, located in the electrical room serving each floor, have been
    included. Additional panels, if required, to distribute the service of 6
    watts per s.f. reserved for tenant power, will be included as a part of the
    TI allowance. Koll has included one (1) 84 pole electrical panel, located in
    each electrical room, for distribution of Tenant's 277 v. lighting.
    Additional lighting panels, if required, for distribution of the 1.5 watts
    per s.f. reserved for tenant lighting, will be included as a part of the TI
    allowance.

7)  One 250 kw emergency generator has been included and it is assumed that life
    safety requirements may be served off of this system. All distribution
    required for life safety is included in the shell building. All distribution
    of emergency power for Tenant use is included in the TI allowance.

                               COMPLETION GUARANTY

         For a valuable consideration, receipt of which is hereby acknowledged,
the undersigned, KOLL DEVELOPMENT COMPANY, LLC, a Delaware limited liability
company (hereinafter called "Guarantor"), absolutely, unconditionally and
irrevocably guarantees for the benefit of LACERTE SOFTWARE CORPORATION, a
Delaware corporation (hereinafter called "Creditor"): (a) to perform fully and
promptly when due all of the covenants, agreements and other obligations
undertaken by KCD-TX I INVESTMENT LIMITED PARTNERSHIP, a Texas limited
partnership (hereinafter called "Obligor") in Section 2.05 of the Office Lease
Agreement by and between Obligor and Creditor dated effective February 22, 2000
(the "Lease Agreement") (such covenants, agreements and other obligations
hereinafter called the "Obligations"); and (b) to pay any and all costs,
reasonable attorneys' fees and expenses incurred or expended by Creditor due to
any default in the performance of the Obligations or in enforcing any right
granted hereunder.

         The liability of Guarantor hereunder shall not be modified, changed,
released, reduced, limited or impaired in any manner whatsoever on account of
any or all of the following: (a) the incapacity, death, disability, dissolution
or termination of Guarantor, Obligor, Creditor or any other person or entity;
(b) the failure by Creditor to file or enforce a claim against the estate
(either in administration, bankruptcy or other proceeding) of Obligor or any
other person or entity; (c) recovery from Obligor or any other person or entity
becomes barred by any statute of limitations or is otherwise prevented; (d) any
defenses, set-offs or counterclaims which may be available to Obligor or any
other person or entity; (e) any release of Obligor, any co-guarantor or any
other person (other than Guarantor) primarily or secondarily liable for the
performance of the Obligations or any part thereof, or (f) any impairment,
modification, change, release or limitation of the liability of, or stay of
actions or lien enforcement proceedings against, Obligor, its property, or its
estate in bankruptcy resulting from the operation of any present or future
provision of the Federal Bankruptcy Code (hereinafter called the "Bankruptcy
Code") or other similar federal or state statute, or from the decision of any
court.

         Creditor shall not be required to pursue any other remedies before
invoking the benefits of the guaranties contained herein. Creditor may maintain
an action on this Guaranty without joining Obligor therein and without bringing
a separate action against Obligor.

         If for any reason whatsoever (including but not limited to ultra vires,
lack of authority, illegality, force majeure, act of God or impossibility) the
Obligations cannot be enforced against Obligor, such unenforceability shall in
no manner affect the liability of Guarantor hereunder and Guarantor shall be
liable hereunder notwithstanding that Obligor may not be liable for such
Obligations and to the same extent as Guarantor would have been liable if such
Obligations had been enforceable against Obligor.

                                       1

<PAGE>   88

         Guarantor absolutely and unconditionally covenants and agrees that in
the event that Obligor does not or is unable so to perform the Obligations for
any reason, including, without limitation, liquidation, dissolution,
receivership, conservatorship, insolvency, bankruptcy, assignment for the
benefit of creditors, sale of all or substantially all assets, reorganization,
arrangement, composition, or readjustment of, or other similar proceedings
affecting the status, composition, identity, existence, assets or obligations of
Obligor, or the disaffirmance or termination of any of the Obligations in or as
a result of any such proceeding, Guarantor shall perform the Obligations and no
such occurrence shall in any way affect Guarantor's obligations hereunder.

         Notwithstanding anything to the apparent contrary contained herein,
Guarantor does not herein expressly or impliedly waive or release any rights of
subrogation that Guarantor may have against Obligor (except as same are
expressly subordinated as provided herein), rights of contribution that
Guarantor may have against any other guarantor of, or other person secondarily
liable for, the performance of the Obligations or rights of reimbursement that
Guarantor may have as against Obligor (except as same may be limited herein).

         The rights of Creditor are cumulative and shall not be exhausted by its
exercise of any of its rights hereunder or otherwise against Guarantor or by any
number of successive actions until and unless all Obligations have been
performed and each of the obligations of Guarantor hereunder has been performed.
The existence of this Guaranty shall not in any way diminish or discharge the
rights of Creditor under any prior or future guaranty agreement executed by
Guarantor.

         Any notice or communication required or permitted hereunder shall be
given in writing, sent by (a) personal delivery, (b) expedited delivery service
with proof of delivery, or (c) United States mail, postage prepaid, registered
or certified mail, sent to the intended addressee at the address shown below, or
to such other address or to the attention of such other person as hereafter
shall be designated in writing by the applicable party sent in accordance
herewith. Any such notice or communication shall be deemed to have been given
and received either at the time of personal delivery or, in the case of delivery
service or mail, as of the date of first attempted delivery at the address and
in the manner provided herein.

         THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF GUARANTOR HEREUNDER
SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO TEXAS' PRINCIPLES
OF CONFLICTS OF LAW) AND THE LAW OF THE UNITED STATES APPLICABLE TO TRANSACTIONS
IN SUCH STATE. GUARANTOR HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE
JURISDICTION OF ANY TEXAS OR FEDERAL COURT SITTING IN DALLAS, TEXAS OVER ANY
SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY, AND
GUARANTOR HEREBY AGREES AND CONSENTS THAT IN ADDITION TO ANY

METHODS OF SERVICE OF PROCESS PROVIDED FOR UNDER APPLICABLE LAW, ALL SERVICE OF
PROCESS IN ANY SUCH SUIT, ACTION OR PROCEEDING IN ANY TEXAS OR FEDERAL COURT
SITTING IN DALLAS. TEXAS MAY BE MADE BY CERTIFIED OR REGISTERED MAIL, RETURN
RECEIPT REQUESTED, DIRECTED TO GUARANTOR AT THE ADDRESS OF GUARANTOR FOR THE
GIVING OF NOTICES HEREUNDER.

         Guarantor hereby expressly and unconditionally waives, in connection
with any suit, action or proceeding brought by Creditor in connection with this
Guaranty, any and every right it may have to (i) injunctive relief, (ii) a trial
by jury, (iii) interpose any counterclaim therein (other than a compulsory
counterclaim) and (iv) have the same consolidated with any other or separate
suit, action or proceeding. Nothing herein contained shall prevent or prohibit
Guarantor from instituting or maintaining a separate action against Creditor
with respect to any asserted claim.

         This Guaranty may be executed in any number of counterparts with the
same effect as if all parties hereto had signed the same document. All such
counterparts shall be construed together and shall constitute one instrument,
but in making proof hereof it shall only be necessary to produce one such
counterpart.

         This Guaranty may only be modified, waived, altered or amended by a
written instrument or instruments executed by the party against which
enforcement of said action is asserted. Any alleged modification, waiver,
alteration or amendment which is not so documented shall not be effective as to
any party. This Guaranty shall lapse and become void and unenforceable upon
Obligor's satisfaction of its obligations under Section 2.05 of the Lease
Agreement.

         The terms, provisions, covenants and conditions hereof shall be binding
upon Guarantor and the successors and assigns of Guarantor and shall inure to
the benefit of Creditor and all transferees, successors and/or assignees of
Creditor. Within this Guaranty, words of any gender shall be held and construed
to include any other gender and words in the singular number shall be held and
construed to include the plural, unless the context otherwise requires. A
determination that any provision of this Guaranty is unenforceable or invalid
shall not affect the enforceability or validity of any other provision and any
determination that the application of any provision of this Guaranty to any
person or circumstance is illegal or unenforceable shall not affect the
enforceability or validity of such provision as it may apply to any other
persons or circumstances.

                                  EXHIBIT "D-1"

                                 Intuit Guaranty

         THIS LEASE GUARANTY ("GUARANTY") is made as of the 22 day of February,
2000, by INTUIT INC., a corporation formed under the laws of Delaware
("GUARANTOR") in favor of KCDTX I INVESTMENT LIMITED PARTNERSHIP, a Texas
limited partnership ("LANDLORD").

         FOR VALUE RECEIVED, Guarantor hereby unconditionally, irrevocably and
absolutely guarantees to Landlord without demand or notice (except for the
notice of default which is delivered to Guarantor under the Lease) the prompt
and full payment and performance, when due, of all obligations and covenants of
LACERTE SOFTWARE CORPORATION, a Delaware corporation ("TENANT"), fixed or
contingent, under the terms of the Office Lease Agreement dated effective
February 22, 2000, executed by and between Tenant and Landlord and any and all,
subject to Paragraph 4 below, renewals, extensions, amendments, expansions and
modifications thereof (collectively, the "LEASE"), or which Tenant, or its
successors or assigns, may in any other manner now or at any time hereafter owe
Landlord under the terms of the Lease, including, but not limited to, rent,
taxes, insurance, operating expenses, maintenance costs, damages and expenses
resulting from Tenant's default under the Lease, (collectively, the
"OBLIGATIONS").

1.       CONTINUING GUARANTY. This is a continuing Guaranty and shall apply to
         any renewals, extensions, and modifications of the Lease.

2.       OTHER REMEDIES. Landlord shall not be required to pursue any other
         remedies before invoking the benefits of this Guaranty; specifically,
         Landlord shall not be required to take any action against Tenant or any
         other person, to exhaust its remedies against any other guarantor of
         the Obligations, any collateral or other security, or to resort to any
         balance of any deposit account or credit on the books of Landlord in
         favor of Tenant or any other person.

3.       OBLIGATIONS NOT IMPAIRED. Prior to performance and satisfaction in
         full of the Obligations, the liability of Guarantor under this
         Guaranty shall not be released or impaired without the prior written
         consent of Landlord. Without limiting the generality of the foregoing,
         the liability of Guarantor shall not be released or impaired on account
         of any of the following events:

         (a)      the voluntary or involuntary liquidation, sale or other
                  disposition of all or substantially all of the assets of
                  Tenant, or any receivership, insolvency, bankruptcy,
                  reorganization or other similar proceedings affecting Tenant
                  or any of its assets;

         (b)      the addition of a new guarantor or guarantors;

         (c)      any bankruptcy or insolvency proceedings against or by Tenant,
                  its property, or its estate or any modification, discharge or
                  extension of the Obligations resulting from the operation of
                  any present or future provision of the United States
                  Bankruptcy Code or any other similar federal or state statute,
                  or from the decision of ay court, it being

<PAGE>   93
                  the intention hereof that Guarantor shall remain liable on the
                  Obligations notwithstanding any act, omission, order, judgment
                  or event which might, but for the provisions hereof, otherwise
                  operate as a legal or equitable discharge of Guarantor;

         (d)      Landlord's failure to use diligence in preserving the
                  liability of any person on the Obligations, or in bringing
                  suit to enforce collection of the Obligations;

         (e)      the substitution or withdrawal of collateral, or release of
                  collateral, or the exercise or failure to exercise by Landlord
                  of any right conferred upon it herein or in any collateral
                  agreement;

         (f)      if Tenant is not liable for any of the Obligations because the
                  act of creating the Obligations is ultra vires, or the
                  officers or person creating the Obligations acted in excess of
                  their authority, or for any reason the Obligations cannot be
                  enforced against Tenant;

         (g)      any payment by Tenant to Landlord if such payment is held to
                  constitute a preference under the bankruptcy laws, or if for
                  any other reason Landlord is required to refund such payment
                  to Tenant or pay the amount thereof to any other party; or

         (h)      any assignment of the Lease or subletting of all or any
                  portion of the Project (as defined in the Lease).

4.       AMENDMENTS AND PROJECT EXPANSIONS. Notwithstanding anything in this
         Guaranty to the contrary, Guarantor shall have no liability for any
         obligations of Tenant incurred as a result of any amendment, extension,
         renewal or modification of the Lease (collectively, an "Amendment"), or
         any Project Expansion (as such term is defined in the Lease), unless
         Guarantor shall have expressly agreed to the same in writing; provided,
         however, that any such Amendment or Project Expansion may be effected
         as between Landlord and Tenant as provided in the Lease without
         Guarantor's consent, but shall not be binding on Guarantor in any way.
         In the event of such an Amendment or Project Expansion effected by
         Landlord and Tenant without Guarantor's consent, Guarantor shall remain
         liable only for those obligations under the Lease which existed prior
         to such Amendment or Project Expansion.

5.       BENEFIT TO GUARANTOR. Guarantor represents and warrants that it derives
         or expects to derive substantial financial and other advantage and
         benefit, directly or indirectly, from the Lease and the Obligations.
         Guarantor acknowledges that, in entering into the Lease, Landlord is
         relying on Guarantor's agreements contained in this Guaranty and on
         Guarantor's creditworthiness. Guarantor acknowledges that Landlord
         would not have entered into the Lease without Guarantor's guarantee of
         the Obligations pursuant to the terms hereof.

6.       DISSOLUTION OF GUARANTOR. Upon the dissolution or bankruptcy of
         Guarantor, the liability of Guarantor shall continue against its assets
         as to all Obligations which shall have been incurred by Tenant.

<PAGE>   94

7.       FINANCIAL STATEMENTS. The Guarantor warrants and represents to Landlord
         that all financial statements heretofore delivered by Guarantor to
         Landlord are true and correct in all material respects, if any.

8.       WAIVER OF NOTICE. Guarantor waives diligence on the part of Landlord in
         the collection and enforcement of the Obligations, notice, demand,
         protest, and waives the right to notice of all extensions, amendments,
         modifications and/or expansions that may be granted to Tenant with
         respect thereto.

9.       MODIFICATION OR CONSENT. No modification, consent or waiver of any
         provision of this Guaranty, nor consent to any departure by Guarantor
         therefrom, shall be effective unless the same shall be in writing and
         signed by Landlord, and then shall be effective only in the specific
         instance and for the purpose for which given. No notice to or demand on
         Guarantor in any case shall, of itself, entitle Guarantor to any other
         or further notice or demand in similar or other circumstances. No delay
         or omission by Landlord in exercising any power or right hereunder
         shall impair any such right or power or be construed as a waiver
         thereof or any acquiescence therein, nor shall any single or partial
         exercise of any such power preclude other or further exercise thereof
         or the exercise of any other right or power hereunder. All rights and
         remedies of Landlord hereunder are cumulative of each other and of
         every other right or remedy which Landlord may otherwise have at law or
         in equity or under any other contract or document, and the exercise of
         one or more rights or remedies shall not prejudice or impair the
         concurrent or subsequent exercise of other rights or remedies.

10.      INDUCEMENT TO LANDLORD. Guarantor acknowledges that this Guaranty is
         given to induce Landlord to enter into the Lease and to extend credit
         to Tenant which would not be extended except in reliance upon this
         Guaranty.

11.      ATTORNEY'S FEES. If a lawsuit is instituted in connection with this
         Guaranty, then the non-prevailing party in such lawsuit agrees to pay
         to the prevailing party all expenses incurred by the prevailing patty
         in connection with such lawsuit (including, but not limited to,
         reasonable attorneys' fees and costs of court).

12.      SUCCESSORS AND ASSIGNS. This Guaranty is for the benefit of Landlord,
         and its successors and/or assigns. Landlord may assign its rights
         hereunder in connection with assignment of the Lease or collaterally or
         absolutely to the Lender (as defined in the Lease); and, upon any such
         assignment, all the terms and provisions of this Guaranty shall inure
         to the benefit of such assignee, to the extent so assigned. The
         liability of Guarantor hereunder shall be binding upon all
         administrators, legal representatives, successors and assigns of
         Guarantor.

13.      HEADINGS. The section headings hereof are inserted for convenience of
         reference only and shall not alter, define or be used in construing the
         text of this instrument.

14.      DEFENSES. Notwithstanding anything to the contrary herein, Guarantor
         shall have available to it all of Tenant's defenses to enforcement of
         the Lease resulting from the acts or omissions

<PAGE>   95

         of Landlord under the Lease, but Guarantor shall not be entitled to
         raise any of Tenant's personal defenses to enforcement of Lease
         obligations, including, but not limited to, bankruptcy, insolvency,
         waiver, laches, ultra vires or lack of authority.

15.      CONSENT TO JURISDICTION. Guarantor hereby consents to the jurisdiction
         of any state or federal court located within the County of Dallas,
         State of Texas and irrevocably agrees that, subject to Landlord's
         election, all actions or proceedings arising out or relating to this
         Guaranty or the Lease shall be litigated in such courts. Guarantor
         accepts for itself and in connection with its properties, generally and
         unconditionally, exclusive jurisdiction of the aforesaid courts and
         waives any defense of forum non conveniens.

16.      TERM. This Guaranty shall terminate only when all of the Obligations
         have been fully performed and satisfied.

17.      GUARANTY OF PAYMENT AND PERFORMANCE. This is an unconditional,
         irrevocable and absolute guaranty of payment and performance and not a
         guaranty of collection.

18.      PAST DUE AMOUNTS. All past due payments of the Obligations shall bear
         interest at the Specified Rate (as defined in the Lease).

19.      REPRESENTATIONS. Guarantor represents and warrants to Landlord that (i)
         Guarantor has executed this Guaranty of its free will and accord, (ii)
         Guarantor has read and understands the term of this Guaranty and the
         Lease, (iii) Guarantor has had the opportunity to have this Guaranty
         and the Lease reviewed by an attorney of Guarantor's choice, and (iv)
         the execution of this Guaranty will benefit, directly or indirectly,
         the Guarantor.

20.      AUTHORITY. This Guaranty has been duly authorized by all appropriate
         corporate action, and the undersigned is an authorized signatory of
         Guarantor, fully empowered to execute this Guaranty.

21.      GOVERNING LAW. This Guaranty shall be governed under the laws of the
         State of Texas, without regard to principles of conflicts of laws.

22.      EFFECTIVENESS. This instrument shall be effective and binding upon
         Guarantor upon Guarantor's execution hereof and delivery hereof to
         Landlord (which delivery may only be by original execution copy), and

         by Landlord of any remedy under the Lease.

23.      SUBSTITUTION. In the event that Tenant is not a Related Party to
         Intuit, Intuit may substitute a guarantor in its place hereunder

                              ATTORNMENT AGREEMENT

         THIS AGREEMENT made effective as of the day of______________, 2000,
between _______________, a __________ (hereinafter called "Lender") and LACERTE
SOFTWARE CORPORATION, a Delaware corporation (hereinafter called "Tenant"),

                                WITNESSETH THAT:

         WHEREAS, Lender will be the owner and holder of a Deed of Trust,
Mortgage and Security Agreement (hereinafter called the "Security Instrument"),
to be recorded in Collin County, Texas, covering the real property described in
Exhibit A and the building and improvements thereon (hereinafter collectively
called the "Mortgaged Premises") securing the payment of a promissory note in
the stated principal amount of $______ payable to the order of Lender;

         WHEREAS, Tenant is the tenant under Lease Agreement (hereinafter called
the "Lease") dated February 22, 2000 made by KCD-TX I INVESTMENT LIMITED
PARTNERSHIP, a Texas limited partnership, as landlord (said landlord and its
successors and assigns occupying the position of landlord under the Lease
hereinafter called "Landlord"), covering certain property (hereinafter called
the "Demised Premises") consisting of all of the Mortgaged Premises; and

         WHEREAS, Tenant and Lender desire to confirm their understanding with
respect to the Lease and the Security Instrument;

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, Lender and Tenant hereby agree and covenant as follows:

         1. Subordination. The Lease now is, and shall at all times and for all
purposes continue to be, subject and subordinate, in each and every respect, to
the Security Instrument, with the provisions of the Security Instrument
controlling in all respects over the provisions of the Lease, it being
understood and agreed that the foregoing subordination shall apply to any and
all increases, renewals, modifications, extensions, substitutions, replacements
and/or consolidations of the Security Instrument, provided that any and all such
increases, renewals, modifications, extensions, substitutions, replacements
and/or consolidations shall nevertheless be subject to the terms of this
Agreement.

         2. Non-Disturbance. So long as (i) Tenant is not in default (beyond any
period given Tenant to cure such default) in the payment of rent or additional
rent or in the performance of any of the other terms, covenants or conditions of
the Lease on Tenant's part to be performed, (ii) the Lease is in full force
and effect according to its original terms, or with such amendments or

                                       1
<PAGE>   99

modifications as Lender shall have approved, and (iii) Tenant attorns to Lender
or a purchaser of the Mortgaged Premises as provided in Paragraph 3, then (a)
Tenant's possession, occupancy, use and quiet enjoyment of the Demised Premises
under the Lease, or any extensions or renewals thereof or acquisition of
additional space or all or any portion of the fee interest in the Mortgaged
Premises which may be effected in accordance with any option therefor in the
Lease, shall not be terminated, disturbed, diminished or interfered with by
Lender in the exercise of any of its rights under the Security Instrument, and
(b) Lender will not join Tenant as a party defendant in any action or
proceeding for the purpose of terminating Tenant's interest and estate under the
Lease because of any default under the Security Instrument.

         3. Attornment. If Lender shall become the owner of the Mortgaged
Premises or the Mortgaged Premises shall be sold by reason of non-judicial or
judicial foreclosure or other proceedings brought to enforce the Security
Instrument or the Mortgaged Premises shall be conveyed by deed in lieu of
foreclosure, the Lease shall continue in full force and effect as a direct Lease
between Lender, or other purchaser of the Mortgaged Premises who shall succeed
to the rights and duties and obligations of Landlord, and Tenant, and Tenant
shall attorn to Lender or such purchaser, as the case may be, upon any such
occurrence and shall recognize Lender or such purchaser, as the case may be, as
the Landlord under the Lease. Such attornment shall be effective and
self-operative without the execution of any further instrument on the part of
any of the parties hereto. Tenant agrees, however, to execute and deliver at any
time and from time to time, upon the request of Landlord or of any holders) of
any of the indebtedness or other obligations secured by the Security Instrument
or any such purchaser, any instrument or certificate which, in the sole
reasonable judgment of the requesting party, is necessary or appropriate, in
connection with any such foreclosure or deed in lieu of foreclosure or
otherwise, to evidence such attornment.

         4. Obligations and Remedies. If Lender shall become the owner of the
Mortgaged Premises or the Mortgaged Premises shall be sold by reason of non-
judicial or judicial foreclosure or other proceedings brought to enforce the
Security Instrument or the Mortgaged Premises shall be conveyed by deed in lieu
of foreclosure, Lender or other purchaser of the Mortgaged Premises, as the case
may be, shall have the same remedies by entry, action or otherwise in the event
of any default by Tenant (beyond any period given Tenant to cure such default)
in the payment of rent or additional rent or in the performance of any of the
other terms, covenants and conditions of the Lease on Tenant's part to be
performed that Landlord had or would have had if Lender or such purchaser had
not succeeded to the interest of Landlord. Upon attornment by Tenant as provided
herein, Lender or such purchaser shall be bound to Tenant under all the terms,
covenants and conditions of the Lease and Tenant shall have the same remedies
against Lender or such purchaser for the breach of an agreement contained in the
Lease that Tenant might have had under the Lease against Landlord if Lender or
such purchaser had not succeeded to the interest of Landlord; provided, however,
that Lender or such purchaser shall not be liable or bound to Tenant:

                                       2
<PAGE>   100

         (a) for any act or omission of any prior landlord (including Landlord)
which constitutes a default or breach of this Agreement; provided, however,
nothing contained herein shall be deemed to be a waiver of Tenant's rights or
remedies against Lender or such purchaser in the event such default is not cured
by Lender or such purchaser after Lender or such purchaser acquires the
Mortgaged Premises; or

         (b) for any offsets or defenses except those based upon or related to
defects or deficiencies in the construction of the Project, which the Tenant
might be entitled to assert against Landlord arising prior to the date Lender
takes possession of Landlord's interest in the Lease or becomes a mortgagee in
possession, subject to Tenant's continued rights of offset and termination for
any default by Landlord which remains uncured; provided that notice of such
default is provided to Lender within a reasonable time after Lender acquires the
Mortgaged Premises;

         (c) for or by any rent or additional rent which Tenant might have paid
for more than thirty (30) days in advance to any prior landlord (including
Landlord) unless such rent is actually received by Lender; or

         (d) by any amendment or modification of the Lease made without Lender's
consent, except for any amendment or modification of a de minimis or
non-material nature; or

         (e) for any security deposit, rental deposit or similar deposit given
by Tenant to a prior landlord (including Landlord) unless such deposit is
actually paid over to Lender or such purchaser by the prior landlord; or

         (f) for any repairs or replacements to or required by the Demised
Premises or the Mortgaged Premises arising prior to the date Lender or such
purchaser takes possession of the Mortgaged Premises provided, however, nothing
contained herein shall be deemed to be a waiver of Tenant's rights or remedies
against Lender or such purchaser in the event such default is not cured by
Lender or such purchaser after Lender or such purchaser acquires the Mortgaged
Premises; or

         (g) for the payment of any leasing commissions or other expenses for
which any prior landlord (including Landlord) incurred the obligation to pay; or

         (h) by any notice given by Tenant to a prior landlord (including
Landlord) unless a copy thereof was also then given to Lender; or

         (i) beyond Lender's or such purchaser's interest in the Mortgaged
Premises, notwithstanding any provision contained in the lease to the contrary,
it being agreed that Lender or such purchaser shall not be liable or responsible
whatsoever under the terns of the Lease after it ceases to own an interest in
the Mortgaged Premises.

<PAGE>   101

         5. No Abridgment. Nothing herein contained is intended, nor shall it be
construed, to abridge or adversely affect any right or remedy of Landlord under
the Lease in the event of any default by Tenant (beyond any period given Tenant
to cure such default) in the payment of rent or additional rent or in the
performance of any of the other terms, covenants or conditions of the Lease on
Tenant's part to be performed.

         6. Notices of Default to Lender. Tenant agrees to give Lender a copy of
any default notice sent by Tenant to Landlord.

         7. Representations by Tenant. Tenant represents and warrants to Lender
that Tenant has validly executed the Lease; the Lease is valid, binding and
enforceable and is in full force and effect in accordance with its terms; the
Lease has not been amended except as stated herein; no rent under the Lease has
been or will be paid more than thirty (30) days in advance of its due date;
there are no defaults existing under the Lease; and, as of this date, no charge,
lien, counterclaim or claim of offset under the Lease, or otherwise, has accrued
against the rents or other charges due or to become due under the Lease.

         8. Rent Payment. If Lender shall become the owner of the Mortgaged
Premises or the Mortgaged Premises shall be sold by reason of non-judicial or
judicial foreclosure or other proceedings brought to enforce the Security
Instrument or the Mortgaged Premises shall be conveyed by deed in lieu of
foreclosure, Tenant agrees to pay all rents directly to Lender or other
purchaser of the Mortgaged Premises, as the case may be, in accordance with the
Lease immediately upon notice of Lender or such purchaser, as the case may be,
succeeding to Landlord's interest under the Lease. Tenant further agrees to pay
all rents directly to Lender immediately upon notice that Lender is exercising
its rights to such rents under the Security Instrument or any other loan
documents (including but not limited to any Assignment of Leases and Rents)
following a default by Landlord or other applicable party. Tenant shall be under
no obligation to ascertain whether a default by Landlord has occurred under the
Security Instrument or any other loan documents. Landlord waives any right,
claim or demand it may now or hereafter have against Tenant by reason of such
direct payment to Lender and agrees that such direct payment to Lender shall
discharge all obligations of Tenant to make such payment to Landlord.

         9. Notice of Security Instrument. To the extent that the Lease shall
entitle Tenant to notice of any deed of trust or security agreement, this
Agreement shall constitute such notice to the Tenant with respect to the
Security Instrument and to any and all other deeds of trust and security
agreements which may hereafter be subject to the terms of this Agreement.

         10. Landlord Defaults. Tenant agrees with Lender that effective as of
the date of this Agreement: (i) except as permitted by the terms of the Lease
for failure to construct the Project in a timely manner, Tenant shall not take
any steps to terminate the Lease for any default by Landlord or any succeeding
owner of the Mortgaged Premises until after giving Lender written notice of such
default, stating the nature of the default and giving Lender thirty (30) days
from receipt of such notice to effect cure of the same, or if cure cannot be
effected within said thirty (30) days due to the

                                       4
<PAGE>   102

nature of the default, Lender shall have a reasonable time to cure provided that
it commences cure within said thirty (30) day period of time and diligently
carries such cure to completion; and (ii) notice to Landlord under the Lease
(oral or written) shall not constitute notice to Lender.

         11. Notice. Any notice or communication required or permitted hereunder
shall be given in writing, sent by (a) personal delivery, or (b) expedited
delivery service with proof of delivery, or (c) United States mail, postage
