    2.03 OPERATING EXPENSES. In the event that Lessor's Operating Expenses for
the Building and/or Project of which the Leased Premises are a part shall, in
any calendar year during the term of this Lease, exceed the sum of the calendar
year 1999 operating expenses per rentable square foot, Lessee shall pay, as
additional rent, Lessee's prorata share of such excess Operating Expenses.
Lessor may invoice Lessee monthly for Lessee's prorata share of the estimated
incurred Operating Expenses for each calendar year, which amount shall be
adjusted each year by Lessor based upon reasonable anticipated Operating
Expenses. Within five (5) months following the close of each calendar year,
Lessor shall provide Lessee with an accounting showing in reasonable detail all
computations of additional rent due under this Section 2.03. In the event that
Lessor's accounting shows that the total of the monthly estimated payments made
by Lessee exceeds the actual amount of additional rent due by Lessee under this
Section 2.03, then so long as Lessee is not in default hereunder, Lessee's
account shall be credited with such amount. In the event that Lessor's
accounting shows that the total of the monthly estimated payments made by Lessee
is less than the actual amount of additional rent due by Lessee under this
Section 2.03, then the accounting shall be accompanied by an invoice for the
additional rent. Notwithstanding any other provision in this Lease, during the
year in which the Expiration Date or sooner termination of the Lease occurs,
Lessor shall have the option to invoice Lessee for Lessee's prorata share of the
excess Operating Expenses based upon the previous year's Operating Expenses. If
this Lease shall terminate on a day other than the last day of a calendar year,
the amount of any additional rent payable by Lessee applicable to the year in
which such termination shall occur shall be prorated on the ratio that the
number of days from the commencement of the calendar year to and including the
termination date bears to 365. Lessee shall have the right, at its own expense
and within a reasonable time, to audit Lessor's books relevant to the additional
rent payable under this Section 2.03 Lessee may, upon not less than thirty (30)
days prior written notice to Lessor, inspect Lessor's records for all Operating
Expenses incurred during the preceding year at Lessor's general offices at such
other location reasonably designated by Lessor at any time during reasonable
business hours within six (6) months after the end of said year. If said
inspection reveals an overpayment of Operating Expenses, Lessor shall reimburse
Lessee its proportionate share of any such overpayment within thirty (30) days
after receipt of proper billing. If said inspection reveals that Lessor
misstated Operation Expenses and insurance expenses by more than five percent
(5%), Lessor shall reimburse Lessee for all costs reasonably incurred in making
such inspection within thirty (30) days after receipt of notice of
determination, and of the amount, of any such misstatement. Lessor's Operating
Expenses for any year shall be deemed correct if Lessee does not give Lessor
written notice of discrepancy within ninety (90) days of receipt of operating
expense notice. Lessee agrees to pay any additional rent due under this Section
2.03 within ten (10) days following receipt of the invoice or accounting showing
additional rent due. The Operating Expenses that vary with occupancy and that
are attributable to any part of the term in which less than one hundred percent
(100%) of the rentable area of the Building is occupied by lessees will be
adjusted by Lessor to the amount Lessor reasonably believes such expenses would
have been ninety-five percent (95%) of the rentable area of the Building had
been occupied. For purposes of determining Operating Expenses for the calendar
year 1999, the real estate taxes will be those imposed on the first year in
which the building is fully assessed as a completed building.

    2.04 LATE PAYMENT CHARGE. Other remedies for nonpayment of rent
notwithstanding, if the monthly base rent and additional rent payment is not
received by Lessor on or before the first day of the month for which the rent is
due, or if any other payment due Lessor by Lessee is not received by Lessor on
or before the first day of the month next following the month in which Lessee
was invoiced, a late payment charge equal to the greater of $250.00 or five
percent (5%) of such past due amount shall become due and payable, after a 5 day
grace period, in addition to such amounts owed under this Lease.

    2.05 INCREASE IN INSURANCE PREMIUMS. If an increase in any insurance
premiums paid by Lessor for the Building is caused by Lessee's use of the Leased
Premises in a manner other than as set forth in Section 1.06, or if Lessee
vacates the Leased Premises and causes an increase in such premiums, then Lessee
shall pay to Lessor, as additional rent, the amount of such increase to Lessor.

    2.06 SECURITY DEPOSIT. The security deposit set forth in Section 1.07 shall
be held by Lessor in a federally insured interest bearing account for the
performance of Lessee's covenants and obligations under this Lease, it being
expressly understood that the security deposit shall not be considered an
advance payment of rental or a measure of Lessor's damage in case of default
hereunder by Lessee. Upon the occurrence of any event of default by Lessee or
breach by Lessee of Lessee's covenants under this Lease, Lessee forfeits any
rights to the interest earned and Lessor may, from time to time, without
prejudice to any other remedy, use the security deposit to the extent necessary
to make good any arrears of base rent or additional rent, or to repair any
damage or injury, or pay any expense or liability incurred by Lessor as a result
of the event of default or breach of covenant, and so long as Lessee is not in
default hereunder, any remaining balance of the security deposit shall be
returned by Lessor to Lessee within thirty (30) days following the fifth
anniversary of the Commencement Date so long as no event of default has occurred
before that date or sooner termination of this Lease. If any portion of the
security deposit is so used or applied, Lessee shall, upon ten (10) days written
notice from Lessor, deposit with Lessor by cash or cashier's check an amount
sufficient to restore the security deposit to its original amount.

    2.07 HOLDING OVER. In the event that Lessee does not vacate the Leased
Premises upon the Expiration Date or sooner termination of this Lease, Lessee
shall be a tenant at will for the holdover period and all of the terms and
provisions of this Lease shall be applicable during that period, except that
Lessee shall pay Lessor as rental for the period of such holdover an amount
equal to 150% of the base rent plus additional rent which would have been
payable by Lessee had the holdover period been a part of the original term of
this Lease. Lessee agrees to vacate and deliver the Leased Premises to Lessor
upon Lessee's receipt of notice from Lessor to vacate. the rental payable
during the holdover period shall be payable to Lessor on demand. No holding over
by Lessee, whether with or without the consent of Lessor, shall operate to
extend the term of this Lease.

the Commencement Date, all costs of removal and/or alterations to be borne by
Lessee. This Section 6.02 shall not apply to moveable equipment or furniture
owned by Lessee, which may be removed by Lessee at the Expiration Date or sooner
termination of the term of this Lease only if Lessee is not then in default and
if such equipment and furniture are not then subject to any other rights, liens
and interest of Lessor.

    6.03 MECHANICS LIEN. Lessee shall not permit any mechanic's or materialman's
lien(s) or other lien to be placed upon the Leased Premises or the Building on
account done by, for or at the request of Lessee and nothing in this Lease
shall be deemed or construed in any way as constituting the consent or request
of Lessor, express or implied, by inference or otherwise, to any person for the
performance of any labor or the furnishing of any materials to the Leased
Premises, or any part thereof, nor as giving Lessee any right, power, or
authority to contract for or permit the rendering of any services or the
furnishing of any materials that would give rise to any mechanic's,
materialman's or other lien against the Leased Premises or the Building. In the
event any such lien is attached to the Leased Premises or the Building, then, in
addition to any other right or remedy of Lessor, Lessor may, but shall not be
obligated to, obtain the release of or otherwise discharge the same. Any amount
paid by Lessor for any of the aforesaid purposes shall be paid by Lessee to
Lessor on demand as additional rent. At Lessor's request, 




                                       4
<PAGE>   8




Lessee shall post a completion bond or other financial security deemed adequate
by Lessor to avoid the potential for the placement of liens upon the property.

                       ARTICLE 7.00 CASUALTY AND INSURANCE

    7.01 SUBSTANTIAL DESTRUCTION. If the Leased Premises should be totally
destroyed by fire or other casualty, or if the Leased Premises should be damaged
so that rebuilding cannot reasonably be completed within ninety (90) working
days after the date of written notification by Lessee to Lessor of the
destruction, this Lease shall terminate and Lessee shall be relieved of its
obligation to pay base rent and additional rent during the unexpired portion of
the Lease, effective as of the date of the written notification.

    7.02 PARTIAL DESTRUCTION. If the Leased Premises should be partially damaged
by fire or other casualty, and rebuilding or repairs can reasonably be completed
within ninety (90) working days from the date of written notification by Lessee
to Lessor of the destruction, this Lease shall not terminate, and Lessor shall
at its sole risk and expense proceed with reasonable diligence to rebuild or
repair the Building or other improvements to substantially the same condition in
which they existed prior to the damage. If the Leased Premises are to be rebuilt
or repaired and are untenantable in whole or in part following the damage, the
rentals payable under this Lease during the period for which the Leased Premises
are untenantable shall be adjusted to such an extent as may be fair and
reasonable under the circumstances.

    7.03 LESSOR'S INSURANCE. At all times during the term of this Lease Lessor
shall maintain a policy of insurance with the premiums paid in advance, issued
by and binding upon an insurance company with a Best rating of A-9 or better,
insuring the Building against all risk of direct physical loss in an amount
equal to at least ninety percent (90%) of the full replacement cost of the
Building and its improvements as of the date of the losses, in addition, Lessor
shall maintain two million dollars in liability insurance, however, Lessor shall
not be obligated in any way or manner to insure any personal property
(including, but not limited to, any furniture, machinery, goods or supplies) of
Lessee upon or within the Leased Premises, any fixtures installed or paid for by
Lessee upon or within the Leased Premises, or any improvements which Lessee may
construct on the Leased Premises. Lessee shall have no right in or claim to the
proceeds of any policy of insurance maintained by Lessor even though the cost of
such insurance is included as a component of Operating Expenses and partially
borne by Lessee as set forth in Section 2.03.

    7.04 WAIVER OF SUBROGATION. Anything in this Lease to the contrary
notwithstanding, Lessor and Lessee hereby waive and release each other of and
from any and all right of recovery, claim, action or cause of action, against
each other, their agents, officers and employees, for any loss or damage that
may occur to the Leased Premises, improvements to the Building of which the
Leased Premises are a part, or personal property within the Building, by reason
of fire or the elements, regardless of cause or origin, including negligence of
Lessor or Lessee and their agents, contractors, officers and employees. Lessor
and Lessee agree immediately to give their respective insurance companies which
have issued policies of insurance covering all risk of direct physical loss,
written notice of the terms of the mutual waivers contained in this Section
7.04, and to have the insurance policies properly endorsed, if necessary, to
prevent the invalidation of the insurance coverage by reason of the mutual
waivers.

    7.05 HOLD HARMLESS. Lessor shall not be liable to Lessee's employees,
contractors, agents, invitees, licensees or visitors, or to any other person,
for an injury to person or damage to property on or about the Leased Premises
caused by any act or omission of Lessee, its agents, servants or employees, or
of any other person entering upon the Leased Premises under express or implied
invitation by Lessee, or caused by the improvements located on the Leased
Premises becoming out of repair, the failure or cessation of any service
provided by Lessor, or caused by leakage of gas, oil, water or steam or by
electricity emanating from the Leased Premises. Lessee agrees to indemnify and
hold harmless Lessor of and from any loss, attorney's fees, expenses or claims
arising out of any such damage or injury.

                            ARTICLE 8.00 CONDEMNATION

    8.01 SUBSTANTIAL TAKING. If all or a substantial part of the Leased Premises
are taken for any public or quasi-public use under any governmental law,
ordinance or regulation, or by right of eminent domain or by purchase in lieu
thereof, and the taking would prevent or materially interfere with the use of
the Leased Premises for the use specified in Section 1.06, then this Lease shall
terminate and Lessee shall be relieved of its obligation to pay base rent and
additional rent during the unexpired portion of the term of this Lease effective
on the date physical possession is taken by the condemning authority. Lessee
shall have no claim to the condemnation award or proceeds in lieu thereof.

    8.02 PARTIAL TAKING. If a portion of the Leased Premises shall be taken for
any public or quasi-public use under any governmental law, ordinance or
regulation, or by right of eminent domain or by purchase in lieu thereof, and
this Lease is not terminated as provided in Section 8.01, Lessor shall, at
Lessor's sole risk and expense, restore and reconstruct the Building and other
improvements on the Leased Premises to the extent necessary to make it
reasonably tenantable. The rental payable during the unexpired portion of the
term of this Lease shall be adjusted to such an extent as may be fair and
reasonable under the circumstances. Lessee shall have no claim to the
condemnation award or proceeds in lieu thereof.

                       ARTICLE 9.00 ASSIGNMENT OR SUBLEASE

    9.01 LESSOR ASSIGNMENT. Lessor shall have the right to sell, transfer or
assign, in whole or in part, its rights and obligations under this Lease and in
the Building to a transferee who is capable of performing Lessor's obligations
under this Lease and assumes and agrees to do so. Any such sale, transfer or
assignment shall operate to release Lessor from any and all liabilities under
this Lease arising after the date of such sale, assignment or transfer.

    9.02 LESSEE ASSIGNMENT. Lessee shall not assign, in whole or in part, this
Lease, or allow it to be assigned, in whole or in part, by operation of law or
otherwise (including without limitation by transfer of a majority interest of
stock, merger, or dissolution, which transfer of majority interest of stock,
merger or dissolution shall be deemed an assignment) or mortgage or pledge the
same, or sublet the Leased Premises, in whole or in part, without the prior
written consent of Lessor which will not be reasonably withheld, conditioned or
delayed, and in no event shall any such assignment or sublease ever release
Lessee or any guarantor from any obligation or liability hereunder. No assignee
or sublessee of the Leased Premises or any portion thereof may assign or sublet
the Leased Premises or any portion thereof without the prior written consent of
Lessor, which will not be unreasonably withheld, conditioned or delayed.

    9.03 CONDITIONS OF ASSIGNMENT. If Lessee desires to assign or sublet all or
any part of the Leased Premises, Lessee shall so notify Lessor at least thirty
(30) days in advance of the date on which Lessee desires to make such assignment
or sublease. Lessee shall submit to Lessor a non-refundable processing fee of
$300.00 for each such requests and shall provide Lessor with a copy of the
proposed assignment or sublease and such information as Lessor might request
concerning the proposed sublessee or assignee to allow Lessor to make informed
judgments as to the financial condition, reputation, operations and general
desirability of the proposed sublessee or assignee. Within fifteen (15) days
after Lessor's receipt of Lessee's proposed assignment or sublease and all
required information concerning the proposed sublessee or assignee, to include a
non-refundable processing fee, Lessor shall have the following options: (1) to
cancel this Lease as to the Leased Premises or portion




                                        5



<PAGE>   9




thereof proposed to be assigned or sublet; (2) to consent to the proposed
assignment or sublease, and, if the rental due and payable by any assignee or
sublessee under any such permitted assignment or sublease (or a combination of
the rent payable under such assignment or sublease plus any bonus or any other
consideration or any payment incident thereto) exceeds the base rent and
additional rent payable under this Lease for such space, Lessee shall pay to
Lessor all such excess rent and other excess consideration within ten (10) days
following receipt thereof by Lessee; or (3) to refuse, in the exercise of its
good faith and reasonable judgement, to consent to the proposed assignment or
sublease, which refusal shall be deemed to have been exercised unless Lessor
gives Lessee written notice providing otherwise. Upon the occurrence of any
event of default, if all or any part of the Leased Premises are then assigned or
sublet, Lessor, in addition to any other remedies provided by this Lease or
provided by law, may, at its option, collect directly from the assignee or
sublessee all rents becoming due to Lessee by reason of the assignment or
sublease, and Lessor shall have a security interest in all properties on the
Leased Premises to secure payment of such sums. Any collection directly by
Lessor from the assignee or sublessee shall not be construed to constitute a
novation or a release of Lessee or any guarantor from the further performance of
its obligations under this Lease.

    9.04 SUBORDINATION. Lessee accepts this Lease subject and subordinate to any
recorded mortgage or deed of trust lien presently existing or hereafter created
upon the Building and to all existing recorded restrictions, covenants,
easements and agreements with respect to the Building. Lessor is hereby
irrevocably vested with full power and authority to subordinate Lessee's
interest under this Lease to any first mortgage or deed of trust lien hereafter
placed on the Leased Premises or the Building, so long as Lessee receives a
subordination, non-disturbance and attornment agreement in form and substance
reasonably satisfactory to it and Lessee shall, upon demand, execute additional
instruments subordinating this Lease as Lessor may require. If the interests of
Lessor under this Lease shall be transferred by reason of foreclosure or other
proceedings for enforcement of any first mortgage or deed of trust lien on the
Leased Premises or the Building, Lessee shall be bound to the transferee
(sometimes hereinafter called the "Purchaser") at the option of the Purchaser,
under the terms, covenants and conditions of this Lease for the balance of the
term of this Lease remaining, including any extensions or renewals, with the
same force and effect as if the Purchaser were Lessor under this Lease, and, if
requested by the Purchaser, Lessee agrees to attorn to the Purchaser, including
the first mortgagee under any such mortgage if it be the Purchaser, as its
Lessor.

    9.05 ESTOPPEL CERTIFICATES. Lessee shall furnish, from time to time, within
ten (10) days after receipt of a request from Lessor or Lessor's mortgagee, a
statement certifying, if applicable, the following: Lessee is in possession of
the Leased Premises; the Leased Premises are acceptable; the Lease is in full
force and effect; the Lease is unmodified; Lessee claims no present charge, lien
or claim of offset against rentals; the base rent and additional rent is paid
for the current month, but is not prepaid for more than one (1) month and will
not be prepaid for more than one (1) month in advance; there is no existing
default by reason of some act or omission by Lessor; and such other matters as
may be reasonably required by Lessor or Lessor's mortgagee. Lessee's failure to
deliver such statement, in addition to being a default under this Lease, shall
be deemed to establish conclusively that this Lease is in full force and effect
except as declared by Lessor, that Lessor is not in default of any of its
obligations under this Lease, and that Lessor has not received more than one (1)
month's Base rent and additional rent in advance.

                       ARTICLE 10.00 DEFAULT AND REMEDIES

    10.01 DEFAULT BY LESSEE. The following shall be deemed to be events of
default by Lessee under this Lease: (1) Lessee shall fail to pay when due any
installment of base rent or additional rent or any other payment required
pursuant to this Lease; or (2) Lessee shall abandon or vacate all or any
substantial portion of the Leased Premises; or (3) Lessee shall fail to comply
with any term, provision or covenant of this Lease, other than the payment of
base rent and additional rent, and the failure is not cured within ten (10) days
after written notice to Lessee, unless the failure cannot reasonably be cured
within ten (10) days, in which event Lessee will not be in default so long as it
commences the cure within ten (10) days and diligently pursues it to completion;
or (4) Lessee shall file a petition or be adjudged bankrupt or insolvent under
any applicable federal or state bankruptcy or insolvency law or admit that it
cannot meet its financial obligations as they become due; or a receiver or
trustee shall be appointed for all or substantially all of the assets of Lessee;
or Lessee shall make a transfer in fraud of creditors or shall make an
assignment for the benefit of creditors; or (5) Lessee shall do or permit to be
done any act which results in a lien being filed against the Leased Premises or
the Building of which the Leased Premises are a part and the lien is not
released within thirty (30) days after Lessee received notice of it.

    10.02 REMEDIES FOR LESSEE'S DEFAULT. Upon the occurrence of any event of
default set forth in this Lease, Lessor shall have the option to pursue any one
(1) or more of the remedies set forth herein without any notice or demand: (1)
Lessor may enter upon and take possession of the Leased Premises, by picking or
changing locks if necessary, and lock out, expel or remove Lessee and any other
person who may be occupying all or any part of the Leased Premises without being
liable for any claim for damages, and relet the Leased Premises on behalf of
Lessee and receive the rental directly by reason of the reletting. Lessee agrees
to pay Lessor on demand any deficiency that may arise by reason of any reletting
of the Leased Premises; further, Lessee agrees to reimburse Lessor for any
expenditures made by it in order to relet the Leased Premises, including, but
not limited to, leasing commissions, remodeling and repair costs. (2) Lessor may
enter upon the Leased Premises, by picking or changing locks if necessary,
without being liable for any claim for damages, and do whatever Lessee is
obligated to do under the terms of this Lease. Lessee shall reimburse Lessor on
demand for any expenses which Lessor may incur in effecting compliance with
Lessee's obligations under this Lease; further, Lessee agrees that Lessor shall
not be liable for any damages resulting to Lessee from effecting compliance with
Lessee's obligations under this Lease caused by the negligence of Lessor or
otherwise. (3) Lessor may terminate this Lease, in which event Lessee shall
immediately surrender the Leased Premises to Lessor, and if Lessee fails to
surrender the Leased Premises, Lessor may, without prejudice to any other remedy
which it may have for possession or arrearage in base rent and/or additional
rent, enter upon and take possession of the Leased Premises, by picking or
changing locks if necessary, and lock out, expel or remove Lessee and any other
person who may be occupying all or any part of the Leased Premises without being
liable for any claim for damages. Lessee agrees to pay on demand the amount of
all loss and damage which Lessor may suffer by reason of the termination of this
Lease under this Section 11.02, whether through inability to relet the Leased
Premises on satisfactory terms or otherwise. Notwithstanding any other remedy
set forth in this Lease, in the event Lessor has provided to Lessee any rent
concessions of any type or character, or waived any base rent and/or additional
rent, and Lessee fails to take possession of the Leased Premises on the
Commencement Date or Completion Date or otherwise defaults at any time during
the term of this Lease, the rent concessions, including any waived base rent
and/or additional rent, shall be cancelled and the amount of the base rent or
other rent concessions shall be due and payable immediately as if no rent
concessions or waiver of any base rent and/or additional rent or other rent
concessions had ever been granted. A rent concession or waiver of base rent
and/or additional rent shall not relieve Lessee of any obligation to pay any
other charge due and payable under this Lease including without limitation any
sum due under section 2.03. Notwithstanding anything contained in this Lease to
the contrary, this Lease may be terminated by Lessor only by mailing or
delivering written notice of such termination to Lessee, and no other act or
omission of Lessor shall be construed as a termination of this Lease.

                        ARTICLE 11.00 SUBSTITUTE PREMISES

    11.01 RELOCATION. In the event Lessor determines to utilize the Leased
Premises for other purposes during the term of this Lease, Lessee agrees to
relocate to other space in the Building designated by Lessor, provided such
other space is of comparable size and contains comparable improvements as the
Leased Premises (the "Substitute Premises"). 

                                       6



<PAGE>   10




    11.02 EXPENSES. Lessor shall pay all of Lessee's reimbursable out-of-pocket
expenses for any such relocation to the Substitute Premises, including the
expenses of moving and reconstruction of improvements. In the event of such
relocation, this Lease shall continue in full force and effect without any
change in the terms or conditions of this Lease, but with the new location
substituted for the old location set forth in Section 1.02 of this Lease and a
revised base rent as set forth in Section 1.04 based upon the comparable rate
per rentable square foot then payable for the Leased Premises.

                        ARTICLE 12.00 HAZARDOUS MATERIALS

    12.01 HAZARDOUS MATERIALS. In the event Hazardous Materials, as defined
below, are discovered to be present in, on, or below the Leased Premises or the
Building, Lessee shall not be required to pay any portion of the penalties,
fines or costs related to the presence of Toxic Materials and their removal,
including any costs incurred to comply with any and all rules, regulations,
codes, ordinances, statutes, and other requirements of any lawful governmental
authority respecting Hazardous Materials, pollution, harmful chemicals and other
materials which existed on or below the Leased Premises or the Building prior to
Lessee's occupancy of the Leased Premises; provided, however, if and to the
extent the presence of such Toxic Materials is directly or indirectly caused by
Lessee or its agents, employees or contractors, Lessee shall, at its sole cost
and expense, remove the same.

As used herein, the term "Hazardous Materials" shall include, but not be limited
to, any hazardous or toxic substance, material or waste which is or becomes

42 U.S.C. (6901 et. seq.) (42 U.S.C. (6903)), or defined as a "hazardous
substance" pursuant to Section 101 of the Comprehensive Environmental Response,
Compensation and Liability Act, 42 U.S.C. (9601 et. seq. (42 U.S.C. 9601)).

Lessee shall not (either with or without negligence) cause or permit the escape,
disposal or release of any biologically or chemically active or other hazardous
substances, or materials in the Leased Premises of the Building. Lessee shall
not allow the storage or use of such substances or materials in any manner not
sanctioned by law or by the highest standards prevailing in the industry for the
storage and use of such substances or materials, nor allow to be brought into
the Building any such materials or substances except to use in the ordinary
course of Lessee's business, and then only after prior written notice is given
to Lessor of the identity of such substances or materials. Without limitation,
Hazardous Materials and materials shall include those described in the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, 42 U.S.C. Section 9601 et. seq., the Resource Conservation and Recovery
Act, as amended, 42 U.S.C. Section 6901 et. seq., any applicable state or local
laws and the regulations adopted under these acts. If any lender or governmental
agency shall ever require testing to ascertain whether or not there has been any
release of Hazardous Materials, then the reasonable costs thereof shall be
reimbursed by Lessee to Lessor upon demand as additional charges if such
requirement applies to the Leased Premises. In addition, Lessee shall execute
affidavits, representations and the like from time to time at Lessor's request
concerning Lessee's best knowledge and belief regarding the presence of
Hazardous Materials on the Leased Premises or the Building. In all events,
Lessee shall indemnify Lessor in the manner elsewhere provided in this Lease
from any release of Hazardous Materials on the Leased Premises or the Building
during the term of this Lease occurring, or elsewhere if caused by Lessee or
persons acting under Lessee. The within covenants shall survive the Expiration
Date or earlier termination of this Lease.

                            ARTICLE 13.00 DEFINITIONS

    13.01 ABANDON. "Abandon" is defined as the vacating of all or a substantial

inclement weather which prevents construction), acts of the public enemy, wars,
insurrections and any other cause not reasonably within the control of Lessor
and which by the exercise of due diligence Lessor is unable, wholly or in part,
to prevent or overcome.

    13.03 BUILDING. "Building" as used in this Lease means the Building
described in Section 1.02, including the Leased Premises and the land upon which
the Building is situated.

    13.04 COMMENCEMENT DATE. "Commencement Date" shall be the date set forth in
Section 1.03. The Commencement Date shall constitute the commencement of the
term of this Lease for all purposes, whether or not Lessee has actually taken

    13.05 COMPLETION DATE. "Completion Date" shall be "Substantial Completion"
of the Leased Premises, Building, parking, landscaping and all Building
specifications as described in Exhibit C, subject only to minor punch list items
that do not interfere with Lessee's use of the Leased Premises for its intended

delivery of the notice in which to take such corrective action as may be
necessary and shall notify Lessee in writing as soon as it deems such corrective
action has been completed and the Leased Premises is ready for occupancy. Upon
completion of construction, Lessee and Lessor shall execute an Acceptance of
Leased Premises/Tenant Estoppel Certificate substantially in the form of Exhibit

Premises have been completed in accordance with the plans and specifications,
are suitable for the purposes for which they are let, and that the Leased
Premises are in a good and satisfactory condition as of the date possession was
so delivered to Lessee, except for latent defects, if any and punch list matters

                           ARTICLE 15.00 MISCELLANEOUS

    15.01 WAIVER. Failure of Lessor to declare an event of default by Lessee
immediately upon its occurrence, or delay in taking any action in connection
with an event of default, shall not constitute a waiver of the default by
Lessee, but Lessor shall have the right to declare the default at any time and
take such action as is lawful or authorized under this Lease. Pursuit of any one
(1) or more of the remedies set forth in Article 11.00 shall not preclude
pursuit of any one (1) or more of the other remedies provided elsewhere in this
Lease or provided by law, nor shall pursuit of any remedy constitute forfeiture
or waiver of any base rent or additional rent or damages accruing to Lessor by
reason of the violation of any of the terms, provisions or covenants of this
Lease. Failure by Lessor to enforce one or more of the remedies provided upon an
event of default by Lessee shall not be deemed or construed to constitute a
waiver of the default or of any other violation or breach of any of the terms,
provisions and covenants contained in this Lease.

    15.02 ACT OF GOD. Lessor shall not be required to perform any covenant or
obligation in this Lease, or be liable in damages to Lessee, so long as the

suit.

    15.04 SUCCESSORS. This Lease shall be binding upon and inure to the benefit
of Lessor and Lessee and their respective heirs, personal representatives,
successors and assigns. It is hereby covenanted and agreed that should Lessor's
interest in the Leased Premises cease to exist for any reason during the term of
this Lease, then notwithstanding the happening of such event, this Lease
nevertheless shall remain unimpaired and in full force and effect, and Lessee
hereunder agrees to attorn to the then owner of the Leased Premises.

    15.05 RENT TAX. If applicable in the jurisdiction where the Leased Premises
is situated, Lessee shall pay and be liable for all rental, sales and use taxes
or other similar taxes, if any, levied or imposed by any city, state, county or
other governmental body having authority, such payments to be in addition to all
other payments required to be paid to Lessor by Lessee under the terms of this
Lease. Any such payment shall be paid concurrently with the payment of the base
