                                      -----

         THIS LEASE, made as of the date specified in the Basic Lease
Information, by and between the landlord specified in the Basic Lease
Information ("Landlord"), and the tenant specified in the Basic Lease
Information ("Tenant").

                              W I T N E S S E T H:

                                   Article 1
                                   ---------

                                    Premises
                                    --------

         1.1 Landlord hereby leases to Tenant, and Tenant hereby leases from
Landlord, for the term and subject to the covenants hereinafter set forth, to
all of which Landlord and Tenant hereby agree, the building specified in the
Basic Lease Information (the "Premises"), which includes the land on which the
Premises are located and the improvements thereon.

                                   Article 2
                                   ---------

                                      Term
                                      ----

         2.1 The term of this Lease shall be the term specified in the Basic
Lease Information, which shall commence on the commencement date specified in
the Basic Lease Information (the "Commencement Date") and, after the expiration
of the Term, unless sooner terminated as hereinafter provided, shall renew on a
yearly basis unless and until terminated by either party upon at least ninety
(90) days prior written notice (the "Expiration Date").

         2.2 If the Commencement Date is not the first day of a calendar month,
Tenant shall pay to Landlord, as additional rent, the Base Rent payable under
Section 3.1, calculated on a per diem basis, for the period from the
Commencement Date until the first day of the next full calendar month. Tenant
shall pay the Base Rent in respect of such period to Landlord on the
Commencement Date.

         2.3 Tenant shall accept the Premises "as is" on the Commencement Date.
Landlord shall have no obligation to construct or install any improvements in
the Premises. Tenant's possession of the Premises shall constitute Tenant's
acknowledgment that the Premises are in all respects in the condition in which
Landlord is required to deliver the Premises to Tenant under this Lease and that
Tenant has examined the Premises and is fully informed to Tenant's satisfaction
of the physical and environmental condition and the utility of the Premises.
Tenant acknowledges that Landlord, its agents and employees and other persons
acting on behalf of Landlord have made no representation or warranty of any kind
in connection with any matter relating to the physical or environmental
condition, value, fitness, use or zoning of the Premises upon which Tenant has
relied directly or indirectly for any purpose.

                                    Article 3
                                    ---------

                                      Rent
                                      ----

         3.1 Tenant shall pay to Landlord the following amounts as rent for the
Premises:

              (a) During the term of this Lease, Tenant shall pay to Landlord,
as base monthly rent, the amount of monthly rent specified in the Basic Lease
Information (the "Base Rent").

              (b) Throughout the term of this Lease, Tenant shall pay, as
additional rent, all other amounts of money and charges required to be paid by
Tenant under this Lease, whether or not such amounts of money or charges are
designated "additional rent." As used in this Lease, "rent" shall mean and
include all Base Rent and additional rent payable by Tenant in accordance with
this Lease.

         3.2 Tenant shall pay, as additional rent all Other Taxes attributable
to Tenant (as defined in Section 5.1) that accrue during or are allocable to the
term of this Lease. Landlord shall pay all Property Taxes (as defined in Section
4.1) that accrued during or are allocable to the term of the Lease.

         3.3 Tenant shall pay all Base Rent to Landlord, in advance, on or
before the first day of each and every calendar month during the term of this
Lease. Tenant shall pay all additional rent upon demand. Tenant shall pay all
rent to Landlord without notice, demand, deduction or offset, in lawful money of
the United States of America, at the address of Landlord specified in the Basic
Lease Information, or to such other person or at such other place as Landlord
may from time to time designate in writing.

         3.4 Tenant acknowledges that the late payment by Tenant of any Base
Rent or additional rent (including the items described in Section 3.2) will
cause Landlord to incur costs and expenses, the exact amount of which is
extremely difficult and impractical to fix. Such costs and expenses will include
administration and collection costs and processing and accounting expenses.
Therefore, if any Base Rent or additional rent is not received by Landlord
within fifteen (15) days after it is due, Tenant shall immediately pay to
Landlord a late charge equal to five percent (5%) of such delinquent amount.
Landlord and Tenant agree that such late charge represents a reasonable estimate
of such costs and expenses and is fair compensation to Landlord for the loss
suffered by Tenant's failure to make timely payment. In no event shall such late
charge be deemed to grant to Tenant a grace period or extension of time within
which to pay any rent or prevent Landlord from exercising any right or enforcing
any remedy available to Landlord upon Tenant's failure to pay all rent due under
this Lease in a timely fashion, including the right to terminate this Lease. All
amounts of money payable by Tenant to Landlord hereunder, if not paid when due,
shall bear interest from the due date until paid at the maximum annual interest
rate allowed by law for business loans (not primarily for personal, family or
household purposes) not exempt from the usury law at such due date or, if there
is no such maximum annual interest rate, at the rate of eighteen percent (18%)
per annum.

addition thereto) of every kind and description, general or special, ordinary or
extraordinary, foreseen or unforeseen, secured or unsecured, whether or not now
customary or within the contemplation of Landlord and Tenant, that are levied,
assessed, charged, confirmed or imposed by any public or government authority on
or against, or otherwise with respect to, the Premises or any part thereof or
any personal property used in connection with the Premises. Property Taxes shall
not include net income (measured by the income of Landlord from all sources),
franchise, inheritance or capital stock taxes of Landlord, unless levied or
assessed against Landlord in whole or in part in lieu of, as a substitute for,
or as an addition to any Property Taxes.

                                   -----------

fees and charges, including all payments related to the cost of providing
facilities or services, whether or not now customary or within the contemplation
of Landlord and Tenant, that are levied, assessed, charged, confirmed or imposed
by any public or government authority upon, or measured by, or reasonably
attributable to the cost or value of Tenant's equipment, furniture, fixtures and
other personal property located in the Premises or the cost or value of any
leasehold improvements made in or to the Premises by or for Tenant, regardless
of whether title to such improvements is vested in Tenant or Landlord. Other
Taxes shall not include Property Taxes or net income (measured by the income of
Landlord from all sources, including without limitation rent), franchise,
inheritance or capital stock taxes of Landlord, unless levied or assessed
against Landlord in whole or in part in lieu of, as a substitute for, or as an
addition to any Other Taxes.

                                       ---

         6.1 The Premises shall be used only for the purpose specified in the
Basic Lease Information and no other purpose without Landlord's prior written
consent, which consent shall not be unreasonably withheld or delayed; provided,
however, Landlord's withholding of consent shall be conclusively presumed
reasonable if the proposed use would materially increase the wear and tear on or
the risk of damage to the Premises above levels or risks resulting from Tenant's
use as of the date of this Lease or the proposed use is for an illegal, immoral
or disreputable purpose. Tenant shall not do or permit to be done in, on or
about the Premises, nor bring or keep or permit to be brought or kept therein,
anything which is prohibited by or will in any way conflict with any law,
ordinance, rule, regulation or order now in force or which may hereafter be
enacted, or which is prohibited by any insurance policy for the Premises, or
will in any way increase the existing rate of, or cause a cancellation of, or
affect any insurance for the Premises. Tenant shall not do or permit anything to
be done in, on or about the Premises which will in any way obstruct or interfere
with the rights of Landlord. Tenant shall not maintain or permit any nuisance
in, on or about the Premises or commit or suffer to be committed any waste in,
on or about the Premises.

Premises with electricity, heating, water, natural gas, lighting replacement for
all lights, restroom supplies, telephone service, window washing, security
service, janitor, scavenger and disposal services, and such other services as
Tenant determines to furnish to the Premises. Landlord shall not be in default
hereunder or be liable for any damage or loss directly or indirectly resulting
from, nor shall the rent be abated or a constructive or other eviction be deemed
to have occurred by reason of, the installation, use or interruption of use of
any equipment in connection with the furnishing of any of the foregoing
services, any failure to furnish or delay in furnishing any such services,
whether such failure or delay is caused by accident or any condition beyond the
control of Landlord or Tenant or by the making of repairs or improvements to the
Premises, or any limitation, curtailment, rationing or restriction on use of
water, electricity, gas or any form of energy serving the Premises, whether such
results from mandatory governmental restriction or voluntary compliance with
governmental guidelines. Tenant shall pay the full cost of all of the foregoing
services as additional rent.

                                   Alterations

              (b) Tenant shall obtain and comply with all building permits and
other governmental permits and approvals required in connection with the work.

temporary or permanent in character, made in or to the Premises by Landlord or
Tenant, shall become part of the Premises and Landlord's property excluding,

                                   ----------

                                    Insurance
                                    ---------

         10.1 Landlord shall not be liable to Tenant for any damage to or loss
or theft of any property or for any bodily or personal injury, illness or death
of any person in, on or about the Premises arising at any time and from any
cause whatsoever, except to the extent caused by the gross negligence or willful
misconduct of Landlord. Tenant waives all claims against Landlord arising from
any liability described in this Section 10.1, except to the extent caused by the
gross negligence or willful misconduct of Landlord.

         10.2 Tenant shall indemnify and defend Landlord against and hold
Landlord harmless from all claims, demands, liabilities, damages, losses, costs
and expenses, including reasonable attorneys' fees and disbursements, arising
from or related to any use or occupancy of the Premises, or any condition of the

damage to any property (including property of employees and invitees of Tenant)
or any bodily or personal injury, illness or death of any person (including
employees and invitees of Tenant) occurring in, on or about the Premises or any
part thereof or any part of the building or the land containing the Premises
arising at any time and from any cause whatsoever (except to the extent caused
by the gross negligence or willful misconduct of Landlord) or occurring outside
the Premises when such damage, bodily or personal injury, illness or death is
caused by any act or omission of Tenant or its agents, officers, employees,
contractors, invitees or licensees. This Section 10.2 shall survive the
termination of this Lease with respect to any damage, bodily or personal injury,
illness or death occurring prior to such termination.

         10.3 Tenant shall, at all times during the term of this Lease and at
Tenant's sole cost and expense, obtain and keep in force comprehensive general

Lease), cross liability, fire legal liability, and premises operations, all on

for bodily or personal injury to, illness of, or death of persons and damage to
property occurring in, on or about the Premises, in sufficient amounts to cover
any such events, and such insurance shall name the Landlord and any other
parties designated by Landlord as additional insureds. Tenant shall, at Tenant's
sole cost and expense, be responsible for insuring Tenant's furniture,
equipment, fixtures, computers, office machines and personal property.

         10.4 Landlord shall, at Landlord's sole cost and expense, be
responsible for obtaining and keeping in force insurance against loss or damage
to the Premises by fire and all other risks of physical loss.

         10.5 All insurance required to be maintained by Tenant under this
Article 10 and all renewals thereof shall be issued by good and responsible
companies qualified to do and doing business in the state where the Premises are
located and having a rating in Best's Insurance Guide of at least A-XI. All

condition that occurred or arose (or the onset of which occurred or arose)
during the policy period, and shall expressly provide that Landlord, although
named as an insured, shall nevertheless be entitled to recover under the policy

policy to be maintained by Tenant, Tenant shall deliver each such policy or a
certified copy and a certificate thereof to Landlord for retention by Landlord.

as required, Landlord shall have the right from time to time to effect such
insurance for the benefit of Tenant or Landlord or both of them and all premiums
paid by Landlord shall be payable by Tenant as additional rent on demand. Tenant

a result of Tenant's failure to obtain and maintain in effect the policies of
insurance required under this Article 10.

property, liability and other insurance (excluding workers' compensation) now or

thereof, or any operations therein, a waiver of all rights of subrogation which
the insurer might otherwise, if at all, have to any claims of Tenant against

or officer, insofar as any thereof relate to or are required by the condition,
use or occupancy of the Premises or the operation, use or maintenance of any
personal property, fixtures, machinery, equipment or improvements in the

                             Assignment or Sublease
                             ----------------------

         12.1 Tenant shall not, directly or indirectly, without the prior
written consent of Landlord (which consent shall not be unreasonably withheld),
assign this Lease or any interest herein or sublease the Premises or any part
thereof, or permit the use or occupancy of the Premises by any person or entity
other than Tenant. This Lease shall not, nor shall any interest herein, be
assignable as to the interest of Tenant involuntarily or by operation of law
without the prior written consent of Landlord. Any of the foregoing acts without
such prior written consent of Landlord shall be void and shall, at the option of
Landlord, constitute a default that entitles Landlord to terminate this Lease.

         12.2 If Landlord consents in writing, Tenant may complete the intended
assignment or sublease subject to the following covenants: (i) no assignment or
sublease shall be valid and no assignee or subtenant shall take possession of
the Premises or any part thereof until an executed duplicate original of such
assignment or sublease, in compliance with Section 12.1, has been delivered to
Landlord, (ii) no assignee or subtenant shall have a right further to assign or
sublease, and (iii) no assignment or sublease whatsoever shall release Tenant
from Tenant's obligations and liabilities under this Lease or alter the primary
liability of Tenant to pay all rent and to perform all obligations to be paid
and performed by Tenant. The acceptance of rent by Landlord from any other
person or entity shall not be deemed to be a waiver by Landlord of any provision
of this Lease. Consent to one assignment or sublease shall not be deemed consent
to any subsequent assignment or sublease. If any assignee, subtenant or
successor of Tenant defaults in the performance of any obligation to be
performed by Tenant under this Lease, Landlord may proceed directly against
Tenant without the necessity of exhausting remedies against such assignee,
subtenant or successor.

                                -----------------

         13.1 Landlord shall have the right to enter the Premises at any time to
(i) inspect the Premises, (ii) exhibit the Premises to prospective purchasers,
lenders or tenants, (iii) determine whether Tenant is performing all of Tenant's
obligations, (iv) perform any obligations of Tenant in accordance with Section
14.5, (v) post notices of non-responsibility, "For sale" and "For lease" signs
in and about the Premises, (vi) make any repairs to the Premises and (vii)
investigate and perform tests to determine Tenant's compliance with Article 21.
Tenant waives all claims for damages for any injury or inconvenience to or
interference with Tenant's business, any loss of occupancy or quiet enjoyment of
the Premises or any other loss occasioned by such entry.

                         Events of Default and Remedies
                         ------------------------------

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

              (a) Tenant fails to pay any Base Rent as and when such rent
becomes due; or

              (b) Tenant fails to pay any additional rent or other amount of
money or charge payable by Tenant hereunder as and when such additional rent or
amount or charge becomes due and payable and such failure continues for more
than thirty (30) days after Landlord gives written notice thereof to Tenant; or

              (c) Tenant fails to perform or breaches any other agreement or
covenant of this Lease to be performed or observed by Tenant as and when
performance or observance is due and such failure or breach continues for more
than thirty (30) days after Landlord gives written notice thereof to Tenant;
provided, however, that if, by the nature of such agreement or covenant, such
failure or breach cannot reasonably be cured within such period of thirty (30)
days, an Event of Default shall not exist as long as Tenant commences with due
diligence and dispatch the curing of such failure or breach within such period
of thirty (30) days and, having so commenced, thereafter prosecutes with
diligence and dispatch and completes the curing of such failure or breach within
a reasonable time; or

              (d) Tenant (i) files, or consents by answer or otherwise to the
filing against it of, a petition for relief under the United States Bankruptcy
Code or for liquidation or to take advantage of any bankruptcy, insolvency or
other debtors' relief law of any jurisdiction, (ii) makes an assignment for the
benefit of its creditors, or (iii) consents to the appointment of a custodian,
receiver, trustee or other officer with similar powers of Tenant or of any
substantial part of Tenant's property; or

              (e) Without consent by Tenant, a court or government authority
enters an order, and such order is not vacated within sixty (60) days, (i)
appointing a custodian, receiver, trustee or other officer with similar powers
with respect to Tenant or with respect to any substantial part of Tenant's
property, or (ii) constituting an order for relief or approving a petition for
relief or reorganization or arrangement or any other petition in bankruptcy or
for liquidation or to take advantage of any bankruptcy, insolvency or other
debtors' relief law of any jurisdiction, or (iii) ordering the dissolution,
winding-up or liquidation of Tenant; or

              (f) This Lease or any estate of Tenant hereunder is levied upon
under any attachment or execution and such attachment or execution is not
vacated within sixty (60) days; or

              (g) Tenant vacates or abandons the Premises.

         14.2 If an Event of Default occurs, Landlord shall have the right at
any time to give a thirty (30) day written termination notice to Tenant and, on
the date specified in such notice, Tenant's right to possession shall terminate
and this Lease shall terminate. Upon such termination, Landlord shall have the
right to recover from Tenant:


                                       9
<PAGE>

              (a) The worth at the time of award of all unpaid rent which had
been earned at the time of termination;

              (b) The worth at the time of award of the amount by which all
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 been
reasonably avoided;

              (c) The worth at the time of award of the amount by which all
unpaid rent for the balance of the term of this Lease after the time of award
exceeds the amount of such rental loss that Tenant proves could be reasonably
avoided; and

              (d) All other amounts necessary to compensate Landlord for all the
detriment proximately caused by Tenant's failure to perform all of Tenant's
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom. The "worth at the time of award" of the amounts
referred to in clauses (a) and (b) above shall be computed by allowing interest
at the maximum annual interest rate allowed by law for business loans (not
primarily for personal, family or household purposes) not exempt from the usury
law at the time of termination or, if there is no such maximum annual interest
rate, at the rate of eighteen percent (18%) per annum. The "worth at the time of
award" of the amount referred to in clause (c) above shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank located
nearest the Premises at the time of award plus one percent (1%). For the purpose
of determining unpaid rent under clauses (a), (b) and (c) above, the rent
reserved in this Lease shall be deemed to be the total rent payable by Tenant
under Article 3 and Article 5 hereof.

         14.3 Even though Tenant has breached this Lease, this Lease shall
continue in effect for so long as Landlord does not terminate Tenant's right to
possession, and Landlord shall have the right to enforce all its rights and
remedies under this Lease, including the right to recover all rent as it becomes
due under this Lease. Acts of maintenance or preservation or efforts to relet
the Premises or the appointment of a receiver upon initiative of Landlord to
protect Landlord's interest under this Lease shall not constitute a termination
of Tenant's right to possession unless written notice of termination is given by
Landlord to Tenant.

         14.4 The remedies provided for in this Lease are in addition to all
other remedies available to Landlord at law or in equity by statute or
otherwise.

         14.5 If Tenant fails to pay any sum of money to be paid by Tenant or to
perform any other act to be performed by Tenant under this Lease, Landlord shall
have the right, but shall not be obligated, and without waiving or releasing
Tenant from any obligations of Tenant, to make any such payment or to perform
any such other act on behalf of Tenant in accordance with this Lease. All sums
so paid by Landlord and all necessary incidental costs shall be deemed
additional rent hereunder and shall be payable by Tenant to Landlord on demand,
together with interest on all such sums from the date of expenditure by Landlord
to the date of repayment by Tenant at the maximum annual interest rate allowed
by law for business loans (not primarily for personal, family or household
purposes) not exempt from the usury law at the date of expenditure or, if there
is no such maximum annual interest rate, at the rate of eighteen percent (18%)
per annum. Landlord shall have, in addition to all other rights and remedies of
Landlord, the same rights and remedies in the event of the nonpayment of such
sums plus interest by Tenant as in the case of default by Tenant in the payment
of rent.

         14.6 If Tenant abandons or surrenders the Premises, or is dispossessed
by process of law or otherwise, any movable furniture, equipment, trade fixtures
or personal property belonging to Tenant and left in the Premises shall be
deemed to be abandoned, at the option of Landlord, and Landlord shall have the
right to sell or otherwise dispose of such personal property in any commercially
reasonable manner.

                              ---------------------

         15.1 If the Premises, or any part thereof, is damaged by fire or other
casualty before the Commencement Date or during the term of this Lease, Landlord
shall repair such damage and restore the Premises to substantially the same or
better condition as existed before the occurrence of such fire or other
casualty, Tenant shall repair and replace all such movable furniture, equipment,
trade fixtures and personal property, and this Lease shall remain in full force
and effect. Any such repair and replacement by Tenant shall be done in
accordance with Article 9. In no event shall rent abate. Provided Tenant is not
in default under this Lease (and no event has occurred which, with the passage
of time, the giving of notice, or both, would constitute a default), and
provided Tenant has (i) delivered to Landlord plans and specifications and a
budget for such repair and restoration (all of which Landlord shall have
approved in its reasonable judgment), and (ii) deposited with Landlord cash in
the sum equal to the excess, if any, of the total cost set forth in such
approved budget over the amount of insurance proceeds received on account of
such casualty, then Landlord shall make available to Tenant all insurance
proceeds actually received by Landlord on account of such casualty, for
application to the costs of such approved repair and restoration.

                                 --------------

         16.1 If a substantial portion of the Premises is taken and the
remaining portion of the Premises is not reasonably suitable for Tenant's
purposes, or if a portion of the Premises is taken resulting in loss of access
to and from the Premises without reasonable substitute access being available,
Landlord and Tenant each shall have the right, by giving written notice to the
other within thirty (30) days after the date of such taking, to terminate this
Lease. If either Landlord or Tenant exercises such right to terminate this Lease
in accordance with this Section , this Lease shall terminate as of the date of
such taking. If neither Landlord nor Tenant exercises such right to terminate
this Lease in accordance with this Section 16.1, this Lease shall terminate as
to the portion of the Premises so taken as of the date of such taking and shall
remain in full force and effect as to the portion of the Premises not so taken,
Tenant shall restore the portion of the Premises not so taken to an integrated

architectural unit in accordance with Article 9 and the Base Rent shall be
reduced as of the date of such taking in the proportion that the rentable area
of the Premises so taken bears to the total rentable area of the Premises. If
all of the Premises is taken by exercise of the power of eminent domain before
the Commencement Date or during the term of this Lease, this Lease shall
terminate as of the date of such taking. If all or any part of the Premises is
taken by exercise of the power of eminent domain, all awards, compensation,
damages, income, rent and interest payable in connection with such taking shall,
except as expressly set forth in this Section 16.1, be paid to and become the
property of Landlord, and Tenant hereby assigns to Landlord all of the
foregoing.

                         Subordination, Merger and Sale
                         ------------------------------

         17.1 This Lease shall be subject and subordinate at all times to the
lien of all mortgages and deeds of trust securing any amount or amounts
whatsoever which may now exist or hereafter be placed on or against the Premises
or on or against Landlord's interest or estate therein, all without the
necessity of having further instruments executed by Tenant to effect such
subordination. Notwithstanding the foregoing, in the event of a foreclosure of
any such mortgage or deed of trust or of any other action or proceeding for the
enforcement thereof, or of any sale thereunder, this Lease shall not be
terminated or extinguished, nor shall the rights and possession of Tenant
hereunder be disturbed, if no Event of Default then exists under this Lease, and
Tenant shall attorn to the person who acquires Landlord's interest hereunder
through any such mortgage or deed of trust. Tenant agrees to execute,
acknowledge and deliver upon demand such further instruments evidencing such
subordination of this Lease to the lien of all such mortgages and deeds of trust
as may reasonably be required by Landlord, but Tenant's covenant to subordinate
this Lease to mortgages or deeds of trust hereafter executed is conditioned upon
each such senior mortgage or deed of trust, or a separate subordination
agreement, containing the commitments specified in the preceding sentence.
Without limiting the generality of the foregoing, Tenant agrees to enter into a
mutually agreeable subordination, nondisturbance and attornment agreement.

         17.2 The voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation thereof, shall not work a merger and shall, at the option of
Landlord, terminate all or any existing subleases or subtenancies or operate as
an assignment to Landlord of any or all such subleases or subtenancies.

         17.3 If the original Landlord hereunder, or any successor owner of the
Premises, sells or conveys the Premises, all liabilities and obligations on the
part of the original Landlord, or such successor owner, under this Lease
accruing after such sale or conveyance shall terminate and the original
Landlord, or such successor owner, shall automatically be released therefrom,
and thereupon all such liabilities and obligations shall be binding upon the new
owner. Tenant agrees to attorn to such new owner.

Landlord a mutually agreeable estoppel certificate.

         19.1 If, without objection by Landlord, Tenant holds possession of the
Premises after expiration of the term of this Lease, Tenant shall become a
tenant from month to month upon the terms herein specified. Such month to month
tenancy may be terminated by either Landlord or Tenant by giving thirty (30)
days' written notice of termination to the other at any time.

or toxic substance, material or waste, or any pollutant or contaminant, or words
of similar import, which is or becomes regulated by any local governmental
authority, the state in which the Premises are located, or the United States
Government. The term "Hazardous Material" includes, but is not limited to, any
material or substance which is, (i) designated as a "hazardous substance"
pursuant to Section 311 of the Federal Water Pollution Control Act (33 U.S.C.
Section 1317), (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), (iii) defined as a "hazardous substance" pursuant

thereof), (vi) petroleum products, (vii) polychlorinated biphenyls, (viii) urea
formaldehyde, (ix) radon gas, (x) radioactive matter, (xi) medical waste, and
(xii) chemicals which may cause cancer or reproductive toxicity.

         20.2 As used herein, the term "Environmental Requirements" means all
laws, ordinances, rules, regulations, orders and other requirements of any
government or public authority now in force or which may hereafter be in force
relating to protection of human health or the environment, including all
requirements pertaining to reporting, licensing, permitting, investigation and
remediation of emissions, discharges, storage, disposal or releases of Hazardous
Materials and all requirements pertaining to the protection of the health and
safety of employees or the public.

         20.3 Tenant shall not permit or conduct the handling, use, generation,
treatment, storage or disposal on, in or about the Premises of any Hazardous
Material without prior written notice to Landlord. Any such notice by Tenant to
Landlord shall be in writing and shall demonstrate to the reasonable
satisfaction of Landlord that such Hazardous Material is necessary to the
business of Tenant and will be handled, used, generated, treated, stored or
disposed of in a manner that complies with all Environmental Requirements. Any
such handling, use, generation, treatment, storage or disposal of any Hazardous
Material permitted by Landlord hereunder shall be in compliance with all
Environmental Requirements.

written notice to Landlord of any notice or other communication regarding any
(i) actual or alleged violation of Environmental Requirements by Tenant or with
respect to the Premises, (ii) actual or threatened migration of Hazardous
Material from the Premises, or (iii) the existence of Hazardous Material in or
on the Premises or regarding any actual or threatened investigation, inquiry,
lawsuit, claim, citation, directive, summons, proceeding, complaint, notice,
order, writ or injunction relating to any of the foregoing.

         20.5 Tenant shall indemnify and defend Landlord against and hold
Landlord harmless from all claims, demands, liabilities, damages, fines,
encumbrances, liens, losses, costs and expenses, including reasonable attorneys'
fees and disbursements, and costs and expenses of investigation, arising from or
related to the existence on or after the Commencement Date of Hazardous Material
in or on the Premises or the actual or threatened migration on or after the
Commencement Date of Hazardous Material from the Premises or the existence on or
after the Commencement Date of a violation of Environmental Requirements by
Tenant or with respect to the Premises. The obligations of Tenant under this
Section 20.5 shall not be affected by any investigation by or on behalf of
Landlord or by any information which Landlord may have or obtain with respect
thereto. Tenant shall, to the reasonable satisfaction of Landlord, perform all
remedial actions necessary to remove any Hazardous Material in or on the
Premises on or after the Commencement Date or to remedy actual or threatened
migration from the Premises of any Hazardous Material or to remedy any actual or
threatened violation of Environmental Requirements, provided such remedial
action is required under Environmental Requirements. This Section 20.5 shall
survive termination of this Lease.

         20.6 If, at any time when the term of this Lease (including any renewal
term) would expire but for the terms of this Section 20.6, a Hazardous Material
exists in, on, about or under the Premises, then the term of this Lease shall
automatically be extended and this Lease shall remain in effect until the
earlier of (i) the completion of all remedial action required under Section
20.5, or (ii) the date specified in a written notice from Landlord to Tenant
terminating this Lease. During any such extension period, Tenant shall perform
all of its obligations under this Lease including payments of all rent due
hereunder.

         21.1 The waiver by Landlord or Tenant of any breach of any covenant in
this Lease shall not be deemed to be a waiver of any subsequent breach of the
same or any other covenant in this Lease, nor shall any custom or practice which
may grow up between Landlord and Tenant in the administration of this Lease be
construed to waive or to lessen the right of Landlord or Tenant to insist upon
the performance by Landlord or Tenant in strict accordance with this Lease. The
subsequent acceptance of rent hereunder by Landlord or the payment of rent by
Tenant shall not waive any preceding breach by Tenant of any covenant in this
Lease, nor cure any Event of Default, nor waive any forfeiture of this Lease or
unlawful detainer action, other than the failure of Tenant to pay the particular
rent so accepted, regardless of Landlord's or Tenant's knowledge of such
preceding breach at the time of acceptance or payment of such rent.

postage prepaid, certified with return receipt requested, or delivered by hand
(which may be through a messenger or recognized delivery or courier service) and
addressed as follows: To Landlord at the address of Landlord specified in the
Basic Lease Information, or at such other place as Landlord may from time to
time designate in a written notice to Tenant; and to Tenant, before the
Commencement Date, at the address of Tenant specified in the Basic Lease
Information, and after the Commencement Date, at the Premises, or at such other
place as Tenant may from time to time designate in a written notice to Landlord.

plural as well as the singular. The words "include," "includes" and "including"
shall be deemed to be followed by the phrase "without limitation." Tenant shall
indemnify and defend Landlord against and hold Landlord harmless from all
claims, demands, liabilities, damages, losses, costs and expenses, including
reasonable attorneys' fees and disbursements, arising out of or resulting from
any failure by Tenant to perform any of its obligations or any breach by Tenant
of any of its representations or warranties in accordance with this Lease. If
there is more than one Tenant, the obligations hereunder imposed upon Tenant
shall be joint and several. Time is of the essence of this Lease and each and
