subject to any Tenant Delays, Tenant shall have the right, upon written notice
to Landlord delivered within five (5) business days after July 1, 2000, to

ARTICLE IV
CONDITION OF DEMISED PREMISES

SECTION 4.1. CONDITION OF PREMISES. Except for Landlord's Work (as defined
herein), Tenant agrees to accept the Premises in an absolutely "as-is"
condition, and Tenant acknowledges that Landlord, its agents, attorneys,
representatives and employees have not and do not make any representations or
warranties, express or implied, to Tenant regarding the Premises, including, but
not limited to: (i) the zoning of the Premises; (ii) the condition of any
underground, above ground or surface improvements; (iii) the size, area, use or
type of the Premises or the fitness of the Premises for any intended or
particular use; (iv) the nature of the soil on and underlying the Premises or
its suitability for development or any other use thereof; (v) any financial
information pertaining to the operation of the Premises; (vi) the status of any
requirements or obligations imposed, implied or to be undertaken by the owner or
developer of the Premises pursuant to any zoning, subdivision, development laws
or agreements with any governmental entities; (vii) the presence or absence of
any toxic wastes, hazardous materials or structural defects in, on or under the
Premises or any improvements thereon; or (viii) the presence or absence of any
rights of any governmental authority, or of owners of property in the vicinity
of the Premises, to obtain reimbursement, recapture or special assessments from
any owner of the Premises for all or a portion of the cost of any utilities,
roads or other improvements heretofore or hereafter located on or in the
vicinity of the Premises (and if such rights exist, Tenant agrees to pay all
sums due pursuant thereto, it being expressly acknowledged and agreed that,
Tenant hereby waives any claim Tenant may have or may hereafter acquire against
Landlord, its agents, attorneys, representatives or employees for said costs),
any and all such representations and warranties, express or implied, being
hereby expressly waived by Tenant and disclaimed by Landlord. Except as
expressly provided for in this Lease, no promise of Landlord to alter, remodel,
decorate, clean or improve the Premises or any portion thereof and no
representation respecting the condition of the' Premises or any portion thereof
have been made by Landlord to Tenant.

ARTICLE V
RENT

SECTION 5.1. BASE RENT. In consideration of the leasing aforesaid, Tenant
agrees to pay Landlord, without offset or deduction, base rent for the Initial
Term ("Base Rent"), payable monthly in advance in the amount of the Monthly Base
Rent set forth in the Base Rent Schedule commencing on the Commencement Date and
continuing on the first (1st) day of each month thereafter for the balance of
the Term of this Lease, and in addition thereto, shall pay such charges as are
herein described as "Additional Rent". The term "Rent" when used in this Lease
shall include all Base Rent payable under this Section 5.1., as well as the
charges herein described as Additional Rent. All Rent payable hereunder shall be
payable to Landlord at 000 X. XxXxxxx Xxxxxx, Xxxx. 0000, Xxxxxxx, Xxxxxxxx
00000-0000, or as Landlord may otherwise from time to time designate in writing.

SECTION 5.2. INTEREST AND LATE CHARGES ON LATE PAYMENTS. Tenant
acknowledges that its late payment of any Rent will cause Landlord to incur
certain costs and expenses not contemplated under this Lease, the exact amount
of which is extremely difficult or impracticable

to fix. Such costs and expenses will include, without limitation, loss of use of
money, administrative and collection costs and processing and accounting
expenses. Therefore, if any installment of monthly Base Rent is not received by
Landlord within five (5) days after the date when due or any other sum due
hereunder is not paid when due, Tenant shall immediately pay to Landlord a late
charge equal to three percent (3%) of the unpaid amount. Such late charge is in
addition to any interest due as set forth below. Landlord and Tenant agree that
this late charge represents a reasonable estimate of costs and expenses incurred
by Landlord from, and is fair compensation to Landlord for, its loss suffered,
by such non-payment by Tenant. In addition to the foregoing, Rent not paid
within thirty (30) days of the date when due shall bear interest from the date
when the same is payable under the terms of this Lease until the same shall be
paid at an annual rate of interest equal to the rate of interest announced from
time to time by the First National Bank of Chicago as its Corporate Base Rate,
plus three percent (3%), unless a lesser rate shall then be the maximum rate
permissible by law, in which event said lesser rate shall be charged ("Lease
Interest Rate"). The term "Corporate Base Rate" means that rate of interest
announced by The First National Bank of Chicago ("First") from time to time as
its "Corporate Base Rate" of interest, changing automatically and simultaneously
with each change in the Corporate Base Rate made by First from time to time. Any
publication issued or published by First from .time to time or a certificate
signed by an officer of First stating its Corporate Base Rate as of a date shall
be conclusive evidence of the Corporate Base Rate on that date. Acceptance of
the late charge shall not constitute a waiver of Tenant's default with respect
to such non-payment by Tenant or prevent Landlord from exercising any other
rights and remedies available to Landlord under this Lease. Failure to pay the
late charge shall constitute a default under this Lease.

ARTICLE VI
TAXES AND IMPOSITIONS

SECTION 6.1. TAXES. Tenant further agrees to pay, as Additional Rent for
the Premises, all Taxes (as hereinafter defined) which accrue during the Term of
this Lease, and are levied, assessed or become a lien imposed upon the Premises
or any part thereof. Notwithstanding the foregoing, the amount of Taxes Tenant
is required to pay shall not exceed the following amounts set forth for the
appropriate period of the Term: $36,355.50 for months 3-14 of the Term;
$42,414.75 for months 15-26 of the Term; $44,596.08 for months 27-38 of the
Term; $46,777.41 for months 3950 of the Term; and $49,201.11 for months 51-62 of
the Term. Such Additional Rent shall be payable notwithstanding the fact that
the amount of such Taxes may not be ascertainable or due and payable until after
the expiration of the Term of this Lease. As used herein, "Taxes" means real
estate taxes, assessments, sewer rents, rates and charges, permit and license
fees, transit taxes, taxes based upon the receipt of rent, and any other
federal, state or local governmental charge, general, special, ordinary or
extraordinary, which may now or hereafter be assessed, accrue or become a lien
against, the Premises or any portion thereof in any year during the Term of this
Lease, and also shall include any personal property taxes (attributable to the
year in which paid) imposed upon the furniture, fixtures, machinery, equipment,
apparatus, systems and appurtenances used in connection with the operation of
the Premises and any fine, penalty, interest or cost that may be added to the
foregoing as a result of Tenant's nonpayment of Landlord's invoice therefor.

Nothing contained herein shall be construed to require Tenant to pay any
franchise, inheritance, estate, succession or transfer tax of Landlord or any
income or excess profits tax assessed upon or in respect of all income of
Landlord or chargeable to or required to be paid by Landlord unless such tax
shall be specifically levied against the rental income of Landlord derived
hereunder (as opposed to a general income tax), which tax shall be paid by
Tenant as part of Taxes hereunder provided said rental income shall be
considered as the sole income of Landlord.

SECTION 6.2. UTILITIES. Tenant shall pay, directly to the appropriate
supplier, all costs of natural gas, electricity, heat, light, power, sewer
service, telephone, water, refuse disposal and other utilities and services
supplied to the Premises. Landlord shall, at Landlord's sole cost and expense,
separately meter the Premises. Landlord shall not in any way be liable or
responsible to Tenant for any cost or damage or expense which Tenant may sustain
or incur if either the quality or character of such service is changed or is no
longer available or suitable for Tenant's requirements.

SECTION 6.3. EXPENSES. The Base Rent shall include all management fees,
annual administrative charges and miscellaneous fees incurred by Landlord during
the Term of this Lease; provided, however, Tenant further agrees to pay as
Additional Rent for the Premises, the charge of one percent (I%) of the Annual
Base Rent payable by Tenant pursuant to the Base Rent Schedule for the
performance of services to be performed by Landlord under the express provisions
of this Lease (the "Expenses"). Except as expressly set forth in this Lease,
Landlord shall not have any obligation to perform any services and Tenant shall
contract for, and pay for, all such services, including, but not limited to all
janitorial, snow plow and landscape services necessary at the Premises during
the Term of the Lease.

SECTION 6.4. DEPOSITS. As security for the obligations contained in
Sections 6.1. and 10.3. hereof, Tenant shall deposit monthly with Landlord, or
such other entity as Landlord may designate, on the first (1st) day of each and
every month of the Term, a sum equal to one twelfth (1/12) of the amount of
Taxes owed by Tenant for the first year of the Term and Landlord's estimate of
the Insurance Premiums (as hereinafter defined). All monthly deposits need not
be kept separate and apart by Landlord and shall be held by Landlord in such
account or accounts as may be authorized by the then current state or federal
banking laws, rules or regulations. The monthly deposits shall be used as a fund
to be applied, to the extent thereof, to the payment of Taxes and Insurance
Premiums, as the same become due and payable. The existence of said fund shall
not limit or alter Tenant's obligation to pay the Taxes and Insurance Premiums
for which the fund was created. Tenant shall not be entitled to interest on said
fund. Tenant shall pay Landlord as its monthly deposit for the period commencing
on the Commencement Date and terminating on the December 31st immediately
thereafter the Initial Deposit. On or prior to each December 31st occurring
within the Term, Landlord shall advise Tenant as to Landlord's estimate of the
monthly deposits that will be required for the next Lease Year (as hereinafter
defined).

SECTION 6.5. ADJUSTMENT STATEMENT. As soon as reasonably feasible after
the expiration of each calendar year contained within the Term ("Lease Year"),
Landlord will furnish Tenant a statement ("Adjustment Statement") showing the
following:

(i) Actual Insurance Premiums for the Lease Year last
ended and the amount of Insurance Premiums payable by Tenant for
such Lease Year;

(ii) The amount of Additional Rent due Landlord for the
Lease Year last ended, less credits for monthly deposits paid, if
any; and

(iii) The monthly deposits due in the current Lease
Year.

SECTION 6.6. PAYMENTS. Within thirty (30) days after Tenant's receipt of
each Adjustment Statement, Tenant shall pay to Landlord:

(i) The amount of Additional Rent shown on said
Adjustment Statement to be due Landlord for the Lease Year last
ended; plus

(ii) The amount, which when added to the monthly
deposits theretofore paid in the current Lease. Year would provide
that Landlord has then received such portion of the monthly deposits
as would have theretofore been paid to Landlord had Tenant paid one
twelfth (1/12) of the monthly deposits, for the current Lease Year,
to Landlord monthly on the first day of each month of such Lease
Year.

During the last Lease Year, Landlord may include in the monthly deposits its
estimate of the Additional Rent which may not be finally determined until after
the expiration of the Term. Tenant's obligation to pay such Additional Rent
shall survive the Term.

SECTION 6.7. PAYMENT ADJUSTMENTS. Tenant's payment of the monthly deposits
for each Lease Year shall be credited against the Additional Rent for such Lease
Year. If the monthly deposits paid by Tenant for any Lease Year exceed the
Additional Rent due for such Lease Year, then Landlord shall give a credit to
Tenant in an amount equal to such excess against the Additional Rent due for the
next succeeding Lease Year, except that if any such excess relates to the last
Lease Year of the Term, then, provided that no default of Tenant exists
hereunder, Landlord shall promptly refund such excess to Tenant. In the event
that Landlord fails to refund such excess to Tenant within forty-five (45) days
after due to be refunded to Tenant under the Lease such excess shall bear
interest thereafter at the Lease Interest Rate until refunded.

SECTION 6.8. RIGHT TO PAY. Landlord shall, at its option, have the right,
without notice to Tenant, at all times during the Term to pay any such Taxes not
timely paid by Tenant, and the amounts so paid, including reasonable expenses,
shall be so much Additional Rent due at the next rent day after any such
payments, with interest at the Lease Interest Rate from the date of payment
thereof.

SECTION 6.9. LANDLORD'S CONTEST OF TAXES. To the extent Landlord desires,
in Landlord's reasonable business judgment, to contest the imposition of any
Taxes against the Land and Improvements, Landlord shall proceed with such
protest in accordance with applicable law. Tenant agrees Taxes shall include all
of Landlord's reasonable costs and expenses, including legal fees and court
costs, in pursuing any such contest whether or not Landlord is

successful in such contest. There shall be deducted from Taxes the amount of any
Taxes refunded in any Lease Year, provided said refund relates to an assessment
year included within the Term of the Lease.

ARTICLE VII
USE

SECTION 7.1. USE. The Premises shall be used for the Use only, and for no
other purpose.

SECTION 7.2. PROHIBITED USES. Tenant shall not permit the Premises, or any
portion thereof, to be used in such manner which impairs Landlord's right, title
or interest in the Premises or any portion thereof, or in such manner which
gives rise to a claim or claims of adverse possession or of a dedication of the
Premises, or any portion thereof, for public use. Tenant shall not use or occupy
the Premises or permit the Premises to be used or occupied contrary to any
statute, rule, order, ordinance, requirement, regulation or restrictive covenant
applicable thereto or in any manner which would violate any certificate of
occupancy affecting the same or which would render the insurance thereon void or
the insurance risk more hazardous, or which would cause structural injury to the
Improvements or cause the value or usefulness of the Premises or any part
thereof to diminish or which would constitute a public or private nuisance or
waste, and Tenant agrees that it will, promptly upon discovery of any such use,
immediately notify Landlord and take all necessary steps to compel the
discontinuance of such use.

ARTICLE VIII
MAINTENANCE, REPAIR AND REPLACEMENTS OF PREMISES

SECTION 8.1. TENANT'S OBLIGATIONS. Tenant agrees, at Tenant's sole cost
and expense, to take good care of the Premises, including the Improvements, but
excluding the structural components (as defined in Section 8.3 below) of the
Building and keep same and all parts thereof, including without limitation, the
entire exterior and interior, parking areas, sidewalks, railroad tracks (if
any), water, sewer, gas and electricity connections, pipes, mains and all other
fixtures, machinery, apparatus, equipment, overhead cranes (if any), and
appurtenances thereto together with any and all alterations and additions
thereto, in good order, condition and repair, suffering no waste or injury.

specified under the Lease, or contracts executed relating to the Project,

contractors shall remain under continuing obligation to maintain the
insurance coverage.

maintained by Landlord shall apply in excess of and not contribute with
insurance provided by the Tenant or Contractor under the Lease.

which Landlord may claim against Tenant and Contractors arising out of or
by reason of Tenant's and Contractor's failure to provide and keep in

premiums not paid or incurred by Tenant and Contractors and which would
have been payable under such insurance, but Landlord shall also be
entitled to recover as damages for such breach the uninsured amount of any

coinsurance by reason of, or damage to, any other premises covered
therein.

(j) All insurance companies shall have a Best rating of not
less than A/VII, or an equivalent rating in the event Best ceases to exist

such other insurance in such amounts as may from time to time be
reasonably required by Landlord or a holder of a Mortgage (defined in
Section 23.1 hereof) against such other insurable hazards as at the time
are commonly insured against in the case of prudent owners of properties
similar to the Project and the Premises, and in that connection Landlord
may require changes in the forms, types and amounts of insurance required
pursuant to this Section or add to, modify or delete other requirements;
and in any event, if under applicable law, rule, regulation or ordinance
of any governmental authority, state or federal, having jurisdiction in
the Premises, liability may be imposed upon Landlord on account of the use
or operation of the Premises or the Project or other improvements,
insurance within limits reasonably satisfactory to Landlord shall be
maintained by Tenant and Contractors against any such liability.

(l) The required insurance to be carried shall not be limited
by any limitations expressed in the indemnification language herein or any
limitation placed on the indemnity therein given as a matter of law.

fire and lightning, the risks covered by what is commonly known as extended
coverage, malicious mischief and vandalism, and all other risks of direct

replacement form basis, of such Improvements. The policy or policies evidencing
such insurance shall be written by a company or companies reasonably
satisfactory to Landlord and to Landlord's mortgagee, if any, and authorized to
do business in the state where the Premises are located, shall name Landlord as
insured thereunder, and shall provide that losses shall be paid to Landlord or
its mortgagee, if applicable. At the request of Landlord, a mortgage clause may

so-called war risk and war damage insurance, earthquake and flood insurance on
the Improvements for not less than one hundred percent (100%) of the full
insurance value above foundation. Such insurance shall provide for payment of

boiler and machinery insurance in an amount equal to the full replacement value

ARTICLE XI
DAMAGE OR DESTRUCTION

SECTION 11.1. DAMAGE OR DESTRUCTION BY FIRE OR CASUALTY. In the event the
Premises are damaged by fire, explosion or other casualty, Landlord shall
diligently proceed with respect to the proposed restoration promptly after
receipt of the insurance proceeds. Landlord shall commence the repair,
restoration or rebuilding thereof and shall complete such restoration, repair or
rebuilding within nine (9) months after the receipt of such proceeds, subject to
extension due to delay because of changes, deletions, or additions in
construction requested by Tenant, acts of Tenant, strikes, lockouts, casualties,
acts of God, war, fuel or energy shortages, material or labor shortages,
governmental regulation or control, severe weather conditions or other causes
beyond the control of Landlord ("Extension Events"). In the event of any such
casualty all insurance proceeds shall be payable to Landlord. In no event shall
Landlord be required to repair or replace any alterations or improvements made
by Tenant which are not related to the Improvements, Tenant's Equipment or any
other fixtures, furnishing and personal property of Tenant. Tenant agrees that
Tenant shall deposit with Landlord prior to the commencement of such restoration
any sums in the amount of the deductible amounts carried by Landlord under its
insurance policies (currently, the amount of such deductible is $5,000.00, but
it is subject to change during the Term provided the amount of the deductible
that Tenant is obligated to pay to Landlord shall not exceed $10,000.00 during
the Term). Landlord's obligation to repair, restore or rebuild the Premises
shall be limited to restoring the Premises to substantially the condition in
which the same existed prior to the casualty. Rent and all other charges payable
by Tenant hereunder shall xxxxx during the period of such repair, restoration or
rebuilding to the extent that the Improvements are not tenantable because of any
damage or destruction. In the event the casualty causes fifty percent (50%) or
more of the Premises to be untenantable during the last twenty-four (24) months
of the Term, Landlord may terminate this Lease as of the date of such casualty
by providing notice to Tenant within thirty (30) days after occurrence of the
fire or other casualty causing the damage, in which event, all insurance
proceeds shall be paid to the Landlord and in addition Tenant shall pay to
Landlord the amount of any deductible carried by Tenant under its insurance
policies.

ARTICLE XII
LIENS

SECTION 12.1. LIEN CLAIMS. Tenant shall not do any act which shall in any
way encumber the title of Landlord in and to the Premises, nor shall any
interest or estate of Landlord in the Premises be in any way subject to any
claim by way of lien or encumbrance, whether by operation of law or by virtue of
any express or implied contract by Tenant, and any claim to or lien upon the
Premises arising from any act or omission of Tenant shall accrue only against
the leasehold estate of Tenant and shall in all respects be subject and
subordinate to the paramount

title and rights of Landlord in and to the Premises. Tenant will not permit the
Premises to become subject to any mechanics', laborers' or materialmen's lien on
account of labor or material furnished to Tenant or claimed to have been
furnished to Tenant in connection with work of any character performed or
claimed to have been performed on the Premises by or at the direction of
sufferance of Tenant; provided, however that Tenant shall have the right to
contest in good faith and with reasonable diligence, the validity of any such
lien or claimed lien if Tenant shall first give to Landlord an amount equal to
one hundred twenty percent (120%) of the amount of the lien or claimed lien
which, together with interest earned thereon, shall be held by Landlord as
security to insure payment thereof and to prevent any sale, foreclosure or
forfeiture of the Premises by reason of non-payment thereof. The amount so
deposited with Landlord shall be held by Landlord in an account established at a
federally insured banking institution until satisfactory removal of said lien or
claim of lien. Any funds provided by Tenant for security against said liens,
will be held in an interest-bearing account with interest to the benefit of
Tenant. On any final determination of the lien or claim for lien, Tenant will
immediately pay any judgment rendered, with all proper costs and charges, and
will, at its own expense, have the lien released and any judgment satisfied.
Should Tenant fail to diligently contest and pursue such lien contest, Landlord
may, at its option, use the sums so deposited to discharge any such lien and
upon the satisfaction of such lien or encumbrance Landlord shall pay all such
sums remaining on deposit to Tenant.

SECTION 12.2. LANDLORD'S RIGHT TO CURE. If Tenant shall fail to contest
the validity of any lien or claimed lien or fail to give security to Landlord to
insure payment thereof, or shall fail to prosecute such contest with diligence,
or shall fail to have the same released and satisfy any judgment rendered
thereon, then Landlord may, at its election (but shall not be so required)
remove or discharge such lien or claim for lien (with the right, in its
discretion, to settle or compromise the same), and any amounts advanced by
Landlord, including reasonable attorneys' fees, for such purposes shall be so
much additional rent due from Tenant to Landlord at the next rent date after any
such payment, with interest thereon at the Lease Interest Rate from the date so
advanced.

ARTICLE XIII
ALTERATIONS AND IMPROVEMENTS

SECTION 13.1. ALTERATIONS. Tenant shall not at any time during the Term of
this Lease make any openings in the roof or exterior walls of the Building or

prior written consent of Landlord; provided, however, upon notice to, but
without the consent of Landlord, Tenant shall have the right to make any
Alterations where same are non-structural, do not require openings on the roof
or exterior walls of the Improvements, do not affect any Building system, and do
not exceed TEN THOUSAND AND NO/100 DOLLARS ($10,000.00) in the aggregate in any
twelve (12)-month period. No Alteration to the Premises for which Landlord's

company acceptable to Landlord, evidencing workmen's compensation coverage, and
insurance coverage in amounts satisfactory to Landlord and protecting Landlord
against public liability and property damage to any person or property, on or
off the Premises, arising out of

and during the making of such alterations, additions or improvements. Any
Alteration by Tenant hereunder shall be done in a good and workmanlike manner in
compliance with any applicable governmental law, statute, ordinance or
regulation. Upon completion of any Alteration by Tenant hereunder, Tenant shall
furnish Landlord with a copy of the "as built" plans covering such construction.
Tenant, at its sole cost and expense, will make all Alterations on the Premises
which may be necessary by the act or neglect of any other person or corporation
(public or private), except Landlord, its agents, employees or contractors.
Before commencing any Alterations, involving an estimated cost of more than TEN

agrees that all contractors engaging in any construction activity by and for the
benefit of Tenant for which Landlord's consent shall be required shall obtain
comprehensive/commercial general liability, worker's compensation and such other

impact on the Premises. Prior to the commencement of any construction activity
for which Landlord's consent shall be required, certificates of such insurance
coverages (and original policies with respect to environmental liability
insurance) shall be provided to Landlord.

SECTION 13.2. OWNERSHIP OF ALTERATIONS. All Alterations (except Tenant's
Equipment, as defined in Section 21.2 hereof), put in at the expense of Tenant
shall become the property of Landlord and shall, unless the Landlord request
their removal, remain upon and be surrendered with the Premises as a part
thereof at the termination of this Lease, without compensation or allowance to
Tenant. Landlord may, at its sole option, request that Tenant, at Tenant's sole
cost, remove any such Alterations and if Tenant shall fail to do so, Landlord
may remove the same and Tenant shall pay the cost of such removal to Landlord
upon demand. Notwithstanding the foregoing, upon Tenant's request prior to such
time as Tenant intends to make any Alteration, Landlord shall indicate to Tenant
whether or not such Alterations must be removed upon surrender of the Premises.

SECTION 13.3. SIGNS. Tenant shall not place any signs on any part of the

be unreasonably withheld, and without the approval of the Village of Mundelein,
provided that: (i) the installation and dimensions of said signage is in strict
accordance with applicable law, ordinances and restrictions; (ii) Tenant
continually maintains said signage in a first-class manner; and (iii)

Tenant, at Tenant's sole cost and expense, removes said signage at the
expiration of the Term and restores the areas in which said signage is placed to
its condition prior to the installation of said signage.

SECTION 13.4. TENANT INDEMNITY. Tenant hereby agrees to indemnify, defend
and hold the Landlord, its beneficiaries, shareholders, partners or members and
their respective agents and employees harmless from any and all liabilities of
every kind and description which may arise out of or be connected in any way
with said Alterations. Subject to the provisions of Article XII, any mechanic's
lien filed against the Premises for work claimed to have been furnished to
Tenant shall be discharged of record by Tenant within ten (10) days thereafter,
at Tenant's expense. Upon completing any Alterations, Tenant shall furnish
Landlord with contractors' affidavits and full and final waivers of lien and
receipted bills covering all labor and materials expended and used. All
Alterations shall comply with all insurance requirements and with all ordinances
and regulations of any pertinent governmental authority. All alterations and
additions shall be constructed in a good and workmanlike manner and only good
grades of materials shall be used.

covenant or condition contained in this Lease, in the event that any Alteration
has any environmental impact on the Premises, Landlord may deny the Tenant the
right to proceed in Landlord's sole and absolute discretion.

CONDEMNATION

SECTION 14.1. TAKING: LEASE TO TERMINATE. In the event the whole of the
Premises shall be taken as a result of the exercise of the power of eminent
domain or condemned for a public or quasi-public use or purpose by any competent
authority or sold to the condemning authority under threat of condemnation, or
in the event a portion of the Premises shall be taken or sold as a result of
such event, and as a result thereof the balance of the Premises cannot be used
for the same purpose as before such taking, sale or condemnation, then and in
either of such events, the Term of this Lease shall terminate as of the date of
vesting of title pursuant to such proceeding or sale. The total award,
compensation or damages received from such proceeding or sale (collectively, the
"Award"), shall be paid to and be the property of Landlord, whether the Award
shall be made as compensation for diminution of the value of the leasehold or
the fee of the Premises or otherwise, and Tenant hereby assigns to Landlord, all
of Tenant's right, title and interest in and to the Award. Tenant shall execute,
immediately upon demand of Landlord, such documents as may be necessary to
facilitate collection by Landlord of any such Award.

SECTION 14.2. TAKING: LEASE TO CONTINUE. In the event that less than
twenty-five percent (25%) of the usable square footage of the building located
on the Premises shall be taken as a result of the exercise of the power of
eminent domain or condemned for a public or quasi-public use or purpose by any
competent authority or sold to the condemning authority under threat of
condemnation, and as a result thereof the balance of the Premises can be used
for the same purpose as before such taking, sale or condemnation, this Lease
shall not terminate and Landlord, at its sole cost and expense, shall, to the
extent practical, promptly repair and restore

the Premises, subject to any Extension Events. Any Award paid as a consequence
of such taking, sale, or condemnation, shall be paid to Landlord. Any sums not
so disbursed shall be retained by Landlord. In the event of a taking of land
only, this Lease shall not terminate and Landlord shall not be obligated to
repair or restore the Premises. In the event that more than twenty-five (25%)
percent of the usable square footage of the building located on the Premises
shall be taken as a result of the exercise of the power of eminent domain or
condemned for a public or quasi-public use or purpose by any competent authority
or sold to the condemning authority under threat of condemnation, then Tenant
shall have the right to terminate this Lease. Tenant's right to terminate shall
be exercised by written notice to Landlord given not less than ten (10) days
after Landlord shall have given Tenant written notice of the actual occurrence
of an event giving rise to Tenant's right to terminate the Lease under this
Section 14.2 and the effective date of such Lease termination shall be the date
upon which the transferee of the condemned portion of said building has the
right to possession thereof.

SECTION 14.3. TENANT'S CLAIM. To the extent permitted by law and subject
to the rights of any lender with respect to the Premises, Tenant shall be
allowed to pursue a claim against the condemning authority (hereinafter referred
to as the "Tenant's Claim") that shall be independent of and wholly separate
from any action, suit or proceeding relating to any award to Landlord for
reimbursement of relocation expenses or for Tenant's Equipment and personal
property, provided: (i) Tenant's Claim shall in no way limit, affect, alter or
diminish in any kind or way whatsoever Landlord's award as a result of such
taking, sale or condemnation; (ii) Tenant's Claim shall in no event include any
claim for any interest in real property, it being expressly understood and
agreed that all sums paid with respect to the real property interests taken,
sold or condemned shall be the sole property of Landlord; and (iii) Tenant's
Claim shall in no event be joined with Landlord's proceeding or argued or heard
concurrently therewith and if the tribunal hearing Tenant's Claim orders such
joinder, Tenant agrees to voluntarily dismiss Tenant's Claim without prejudice
until such time as Landlord has received its award for such taking, sale or
condemnation.

ARTICLE XV
RENT ABSOLUTE

SECTION 15.1. RENT ABSOLUTE. This Lease shall be deemed and construed to
be a "net lease" and Tenant agrees to pay all costs and expenses of every kind
and nature whatsoever, ordinary and extraordinary, arising out of or in
connection with the ownership, maintenance, repair, replacement, use and
occupancy of the Premises during the Term of this Lease (except for Landlord's
obligations under Section 8.3 herein) which, except for the execution and
delivery hereof, would otherwise have been payable by Landlord.

ARTICLE XVI
ASSIGNMENT -- SUBLETTING BY TENANT

SECTION 16.1. NO ASSIGNMENT, SUBLETTING OR OTHER TRANSFER. Tenant shall
not assign this Lease or any interest hereunder, nor shall Tenant sublet or
permit the use or occupancy of the Premises or any part thereof by anyone other
than Tenant, without the express prior written

consent of Landlord, which consent shall not be unreasonably withheld or
delayed. No assignment or subletting shall relieve Tenant of its obligations
hereunder, and Tenant shall continue to be liable as a principal and not as a
guarantor or surety, to the same extent as though no assignment or sublease had
been made, unless specifically provided to the contrary in Landlord's consent.
Consent by Landlord pursuant to this Article shall not be deemed, construed or
held to be consent to any additional assignment or subletting, but each
successive act shall require similar consent of Landlord. Landlord shall be
reimbursed by Tenant for any reasonable costs or expenses incurred pursuant to
any request by Tenant for consent to any such assignment or subletting. In the
consideration of the granting or denying of consent, Landlord may, at its
option, take into consideration: (i) the business reputation and credit
worthiness of the proposed subtenant or assignee; (ii) any required alteration
of the Premises; (iii) the intended use of the Premises by the proposed
subtenant or assignee; and (iv) any other factors which Landlord shall deem
relevant.

SECTION 16.2. OPERATION OF LAW. Tenant shall not allow or permit any
transfer of this Lease, or any interest hereunder, by operation of law, or
convey, mortgage, pledge or encumber this Lease or any interest hereunder.

SECTION 16.3. EXCESS RENTAL. If Tenant shall, with Landlord's prior
consent as herein required, sublet the Premises, an amount equal to one hundred
percent (100%) of the rental in excess of the base rent and any additional rent
herein provided to be paid shall be for benefit of Landlord and shall be paid to
Landlord promptly when due under any such subletting as additional rent due
hereunder.

SECTION 16.4. MERGER OR CONSOLIDATION. If Tenant is a corporation whose
stock is not publicly traded, any transaction or series of transactions
(including, without limitation, any dissolution, merger, consolidation or other
reorganization of Tenant, or any issuance, sale, gift, transfer or redemption of
any capital stock of Tenant, whether voluntary, involuntary or by operation of
law, or any combination of any of the foregoing transactions) resulting in the
transfer of control of Tenant, other than by reason of death, shall be deemed to
be a voluntary assignment of this Lease by Tenant subject to the provisions of
this Section 16. If Tenant is a partnership, any transaction or series of
transactions (including without limitation any withdrawal or admittance of a
partner or a change in any partner's interest in Tenant, whether voluntary,
involuntary or by operation of law, or any combination of any of the foregoing
transactions) resulting in the transfer of control of Tenant, other than by
reason of death, shall be deemed to be a voluntary assignment of this Lease by
Tenant subject to the provisions of this assignment of this Lease by Tenant
subject to the provisions of this Section 16. If Tenant is a corporation, a
change or series of changes in ownership of stock which would result in direct
or indirect change in ownership by the stockholders or an affiliated group of
stockholders of less than fifty percent (50%) of the outstanding stock as of the
date of the execution and delivery of this Lease shall not be considered a
change of control. Notwithstanding the immediately foregoing, Tenant may, upon
notice to, but without Landlord's consent, assign this Lease to any corporation
resulting from a merger or consolidation of Tenant, provided that the total
assets and the total net worth of such assignee after such consolidation or
merger shall be in excess of the greater of (i) the net worth of Tenant
immediately prior to such consolidation or merger, or (ii) the net worth of
Tenant as of the date hereof, determined by generally accepted accounting
principles and provided that Tenant is not at such time in default hereunder,
and provided further

that such successor shall execute an instrument in writing, acceptable to
Landlord in its reasonable discretion, fully assuming all of the obligations and
liabilities imposed upon Tenant hereunder and deliver the same to Landlord.
Tenant shall provide in its notice to Landlord such information as may be
reasonably required by Landlord to determine that the requirements of this
Section 16.4 have been satisfied. As used in this Section 16.4, the term
"control" means possession of the power to vote not less than a majority
interest of any class of voting securities and partnership or limited liability
company interests or to direct or cause the direction (directly or indirectly)
off the management or policies of a corporation, or partnership or limited
liability company through the ownership of voting securities, partnership
interests or limited liability company interests, respectively.

SECTION 16.5. UNPERMITTED TRANSACTION. Any assignment, subletting, use,
occupancy, transfer or encumbrance of this Lease or the Premises without
Landlord's prior written consent shall be of no effect and shall, at the option
of Landlord, constitute a default under this Lease.

ARTICLE XVII
ANNUAL STATEMENTS

SECTION 17.1. ANNUAL STATEMENTS. Only in the events that Landlord is
seeking financing for the Premises or Landlord is seeking to sell the Premises,
or in the event Tenant is in default under the terms hereunder, Tenant agrees to
furnish Landlord within fifteen (15) days after request, a copy of its most
recent annual statements prepared in accordance with generally accepted
accounting principles together with applicable footnotes and any other financial
information reasonably requested by Landlord (hereinafter collectively referred
to as, the "Financial Information") and agrees that Landlord may deliver such
Financial Information to any mortgagee, prospective mortgagee or prospective
purchaser of the Premises, provided, however, that only with respect to a
prospective purchaser of the Premises, Landlord must obtain a confidentiality
agreement in the same term as the Confidentiality Agreement dated July 27, 1999
by and between Landlord and Tenant ("Confidentiality Agreement") from such
prospective purchaser regarding the Financial Information before delivering such
Financial Information. Except for the deliveries allowed above or pursuant to
any court order, Landlord agrees to keep such Financial Information confidential
pursuant to the terms of the Confidentiality Agreement

ARTICLE XVIII
INDEMNITY FOR LITIGATION

SECTION 18.1. INDEMNITY FOR LITIGATION. Tenant agrees to pay, and to
indemnify and defend Landlord against, all costs and expenses (including
reasonable attorneys' fees) incurred by or imposed upon Landlord by or in
connection with any litigation to which Landlord becomes or is made a party
without fault on its part, whether commenced by or against Tenant, or any other
person or entity or that may be incurred by Landlord in enforcing any of the
covenants and agreements of this Lease with or without the institution of any
action or proceeding relating to the Premises or this Lease, or in obtaining
possession of the Premises after an Event of Default hereunder or upon
expiration or earlier termination of this Lease. The foregoing notwithstanding,
Tenant's responsibility under this Section 18.1 to pay Landlord's costs and

expenses (including reasonable attorneys' fees) shall not extend to such costs
and expenses incurred in defending an action brought by Tenant to enforce the
terms of this Lease in which there is a court determination that Landlord failed
to perform its obligations under this Lease. The provisions of this Section 18.1
shall survive the expiration or earlier termination of this Lease.

SECTION 18.2. LANDLORD'S INDEMNITY. Landlord agrees to pay, and to
indemnify and defend Tenant against all costs and expenses (including reasonable
attorney's fees) incurred by or imposed upon Tenant by or in connection with any
litigation by Tenant to enforce Landlord's obligations under this Lease in which
Tenant is the prevailing party.

ARTICLE XIX
ESTOPPEL CERTIFICATES

SECTION 19.1. ESTOPPEL CERTIFICATE. Tenant agrees that on the Commencement
Date and at any time and from time to time thereafter, upon not less than ten
(10) days' prior written request by Landlord, it will execute, acknowledge and
deliver to Landlord, or Landlord's mortgagee to the extent factually accurate, a
statement in writing in the form of EXHIBIT "B" attached hereto and by this
reference incorporated herein; provided, however, Tenant agrees to certify to
any prospective purchaser or mortgagee any other reasonable information
specifically requested by such prospective purchaser or mortgagee.

ARTICLE XX
INSPECTION OF PREMISES

SECTION 20.1. INSPECTIONS. Tenant agrees to permit Landlord and any
authorized representatives of Landlord, to enter the Premises at all reasonable
times on reasonable advance notice not to unreasonably disrupt Tenant's business
at the premises, except in the case of emergency, for the purpose of inspecting
the same. Any such inspections shall be at Landlord's sole expense and solely
for Landlord's purposes and may not be relied upon by Tenant or any other
person.

SECTION 20.2. SIGNS. Tenant agrees to permit Landlord and any authorized
representative of Landlord to enter the Premises at all reasonable times during
business hours on reasonable advance notice to exhibit the same for the purpose
of sale, mortgage or lease, and during the final six (6) months of the Term
hereof or any extension thereof, Landlord may display on the Premises customary
"For Sale" or "For Rent" signs.

ARTICLE XXI
FIXTURES

SECTION 21.1. BUILDING FIXTURES. All improvements and all plumbing,
heating, lighting, electrical and air-conditioning fixtures and equipment, and
other articles of personal property used in the operation of the Premises (as
distinguished from operations incident to the

business of Tenant), whether or not attached or affixed to the Premises
("Building Fixtures"), shall be and remain a part of the Premises and shall
constitute the property of Landlord.

SECTION 21.2. TENANT'S EQUIPMENT. All of Tenant's trade fixtures and all
personal property, fixtures, apparatus, machinery and equipment now or hereafter
located upon the Premises, other than Building Fixtures, as shall be and remain
the personal property of Tenant, and the same are herein referred to as
"Tenant's Equipment."

SECTION 21.3. REMOVAL OF TENANT'S EQUIPMENT. Tenant's Equipment may be
removed from time to time by Tenant; provided, however, that if such removal
shall injure or damage the Premises, Tenant shall repair the damage and place
the Premises in the same condition as it would have been if such Tenant's
Equipment had not been installed.

ARTICLE XXII
DEFAULT

SECTION 22.1. EVENTS OF DEFAULT. Tenant agrees that any one or more of the
following events shall be considered "Events of Default" as said term is used
herein:

(a) If an order, judgment or decree shall be entered by any
court adjudicating Tenant a bankrupt or insolvent, or approving a petition
seeking reorganization of Tenant or appointing a receiver, trustee or
liquidator of Tenant, or of all or a substantial part of its assets, and
such order, judgment or decree shall continue unstayed and in effect for
any period of sixty (60) days; or

(b) Tenant shall file an answer admitting the material
allegations of a petition filed against Tenant in any bankruptcy,
reorganization or insolvency proceeding or under any laws relating to the
relief of debtors, readjustment or indebtedness, reorganization,
arrangements, composition or extension; or

(c) Tenant shall make any assignment for the benefit of
creditors or shall apply for or consent to the appointment of a receiver,
trustee or liquidator of Tenant, or any of the assets of Tenant; or

(d) Tenant shall file a voluntary petition in bankruptcy, or
shall admit in writing its inability to pay its debts as they come due, or
shall file a petition or an answer seeking reorganization or arrangement
with creditors or take advantage of any insolvency law; or

(e) A decree or order appointing a receiver of the property of
Tenant shall be made and such decree or order shall not have been vacated
within sixty (60) days from the date of entry or granting thereof; or

(f) Tenant shall default in making any payment of Rent or
other payment required to be made by Tenant hereunder when due as herein
provided, and such default continues for five (5) days after written
notice from Landlord; provided, however, that if Tenant defaults more than
two (2) times in any such payment in any consecutive

twelve (12) month period, then no written notice of such third default or
any subsequent default from Landlord shall be required; or

(g) Tenant shall be in default in the performance of or
compliance with any of the agreements, terms, covenants or conditions in
this Lease other than those referred to in the foregoing subparagraphs (a)
through (g) of this Section for a period of twenty (20) days after notice
from Landlord to Tenant specifying the items in default, or in the case of
a default which cannot, with due diligence, be cured within said twenty
(20)-day period, Tenant fails to proceed within said twenty (20)-day
period to cure the same and thereafter to prosecute the curing of such
default with due diligence (it being intended in connection with a default
not susceptible of being cured with due diligence within said twenty
(20)-day period that the time of Tenant within which to cure the same
shall be extended for such period as may be necessary to complete the same
with all due diligence).

Upon the occurrence of any one or more of such Events of Default, Landlord
may at its election terminate this Lease or terminate Tenant's right to
possession only, without terminating this Lease. Upon termination of this Lease
or of Tenant's right to possession, Tenant shall immediately surrender
possession and vacate the Premises, and deliver possession thereof to Landlord,
and Landlord or Landlord's agents may immediately or any time thereafter without
notice, re-enter the Premises and remove all persons and all or any property
therefrom, either by any suitable action or proceeding at law or equity or by
force or otherwise, without being liable in indictment, prosecution or damages,
therefor, and repossess and enjoy the Premises, together with the right to
receive all income of, and from, the Premises.

Upon termination of this Lease, Landlord shall be entitled to recover as
liquidated damages, because the parties hereto recognize that as of the date
hereof actual damages are not ascertainable and are of imprecise calculation and
not as a penalty, all Rent and other sums due and payable by Tenant through the
date of termination plus (i) an amount equal to sixty percent (60%) of the Rent
and other sums provided herein to be paid by Tenant for the residue of the Term,
and (ii) the costs of performing any other covenants to be performed by Tenant.

If Landlord elects to terminate Tenant's right to possession only, without
terminating this Lease, Landlord may, at Landlord's option, enter into the
Premises, remove Tenant's signs and other evidences of tenancy, and take and
hold possession thereof as hereinabove provided, without such entry and
possession terminating this Lease or releasing Tenant, in whole or in part, from
Tenant's obligations to pay the Rent hereunder for the full Term or from any
other obligations of Tenant under this Lease. Landlord shall use commercially
reasonably efforts to relet all or any part of the Premises for such rent and
upon terms as are commercially reasonable (including the right to relet the
Premises for a term greater or lesser than that remaining of the Term of
premises and the right to relet the Premises as a part of a larger area, the
right to change the character or use made of the Premises and the right to grant
concessions of free rent). For the purpose of such reletting, Landlord may
decorate or make any repairs, changes, alterations, or additions in or to the
Premises that may be necessary or desirable. If, after thirty (30) days from the
occurrence of the Event of Default, Landlord is unable to relet the Premises
after using such commercially reasonably efforts to do so, Landlord shall have
the right to terminate this Lease, in which event, Tenant shall pay to Landlord
liquidated damages (because the parties hereto

recognize that as of the date hereof actual damages are not ascertainable and
are of imprecise calculation and not as a penalty) equal to sixty percent (60%)
of the Rent, and other sums provided herein to be paid by Tenant for the
remainder of the Term. If the Premises are relet and sufficient sums shall not
be realized from such reletting after payment of all expenses of such
decorations, repairs, changes, alterations, additions and the expenses of
repossession and such reletting, and the collection of the Rent herein provided
and other payments required to be made by Tenant under the provisions of this
Lease for the remainder of the Term of this Lease then, in such event, Tenant
shall pay to Landlord on demand any such deficiency and Tenant agrees that
Landlord may file suit to recover any sums falling due under the terms of this
Section from time to time, and all costs and expenses of Landlord, including
attorneys' fees, incurred in connection with any such suit shall be paid by
Tenant.

SECTION 22.2. WAIVERS. Tenant hereby expressly waives, so far as permitted
by law, the service of any notice of intention to re-enter provided for in any
statute, and except as is herein otherwise provided. Tenant for and on behalf of
itself and all persons claiming through or under Tenant, also waives any and all
rights of redemption or re-entry or repossession in case Tenant shall be
dispossessed by a judgment or by warrant of any court or judge or in case of
re-entry or repossession by Landlord or in case of any expiration or termination
of this Lease.. The terms "enter," "re-enter," "entry" or "re-entry" as used in
this Lease are not restricted to their technical legal meanings.

SECTION 22.3. BANKRUPTCY. If Landlord shall not be permitted to terminate
this Lease, as provided in this Article XXII because of the provisions of the
United States Code relating to Bankruptcy, as amended (the "Bankruptcy Code"),
then Tenant as a debtor-in-possession or any trustee for Tenant agrees promptly,
within no more than sixty (60) days after the filing of the bankruptcy petition,
to assume or reject this Lease. In such event, Tenant or any trustee for Tenant
may only assume this Lease if: (a) it cures or provides adequate assurances that
the trustee will promptly cure any default hereunder; (b) compensates or
provides adequate assurance that Tenant will promptly compensate Landlord of any
actual pecuniary loss to Landlord resulting from Tenant's default; and (c)
provides adequate assurance of performance during the fully stated term hereof
of all of the terms, covenants, and provisions of this Lease to be performed by
Tenant. In no event after the assumption of this Lease shall any then-existing
default remain uncured for a period in excess of the earlier of ten (10) days or
the time period set forth herein. Adequate assurance of performance of this
Lease, as set forth hereinabove, shall include, without limitation, adequate
assurance: (i) of the source of rent reserved hereunder; and (ii) that the
assumption of this Lease will not breach any provision hereunder.

If Tenant assumes this Lease and proposes to assign the same pursuant to
the provisions of the Bankruptcy Code to any person or entity who shall have
made a bona fide offer to accept an assignment of this Lease on terms acceptable
to Tenant, then notice of such proposed assignment, setting forth: (i) the name
and address of such person; (ii) all of the terms and conditions of such offer,
and (iii) the adequate assurance to be provided Landlord to assure such person's
future performance under the Lease, including, without limitation, the assurance
referred to in Section 365(b)(3) of the Bankruptcy Code, shall be given to
Landlord by the Tenant no later than twenty (20) days after receipt by the
Tenant but in any event no later than ten (10) days prior to the date that the
Tenant shall make application to a court of competent jurisdiction for authority
and approval to enter into such assignment and assumption, and

Landlord shall thereupon have the prior right and option, to be exercised by
notice to the Tenant given at any time prior to the effective date of such
proposed assignment, to accept an assignment of this Lease upon the same terms
and conditions and for the same consideration, if any, as the bona fide offer
made by such person, less any brokerage commissions which may be payable out of
the consideration to be paid by such person for the assignment of this Lease.

If this Lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code any and all monies or other considerations
payable or otherwise to be delivered to Landlord, shall be and remain the
exclusive property of Landlord and shall not constitute property of Tenant or of
the estate of the Tenant within the meaning of the Bankruptcy Code. Any and all
monies or other considerations constituting the Landlord's property under the
preceding sentence not paid or delivered to the Landlord shall be held in trust
for the benefit of Landlord and shall be promptly paid to the Landlord.

Any person or entity to which this Lease is assigned pursuant to the
provisions of the Bankruptcy Code shall be conclusively deemed without further
act or deed to have assumed all of the obligations arising under this Lease on
and after the date of such assignment. Any such assignee shall upon demand
execute and deliver to Landlord an instrument confirming such assumption. Any
such assignee shall be permitted to use the Leased Premises only for the Use.

Nothing contained in this Section shall, in any way, constitute a waiver
of the provisions of Article XVI of this Lease relating to alienation. Tenant
shall not, by virtue of this section, have any further rights relating to
assignment other than those granted in the Bankruptcy Code. Notwithstanding
anything in this Lease to the contrary, all amounts payable by Tenant to or on
behalf of Landlord under this Lease, whether or not expressly denominated as
rent, shall constitute rent for the purpose of Section 501(b)(6) or any
successive section of the Bankruptcy Code.

ARTICLE XXIII
LANDLORD'S PERFORMANCE OF TENANT'S COVENANTS

SECTION 23.1. LANDLORD'S RIGHT TO PERFORM TENANT'S OBLIGATIONS. In the
event Tenant shall fail to maintain any insurance required to be paid by it
under the terms hereof, or in an Emergency Situation or upon occurrence of an
Event of Default, Landlord may (but shall not be obligated so to do), and
without waiving or releasing Tenant from any obligation of Tenant hereunder,
make any payment or perform any other act which Tenant is obligated to make or
perform under this Lease in such manner and to such extent as Landlord may deem
desirable; and in so doing Landlord shall also have the right to enter upon the
Premises for any purpose reasonably necessary in connection therewith and to pay
or incur any other necessary and incidental costs and expenses, including
reasonable attorneys' fees. All sums so paid and all liabilities so incurred by
Landlord, together with interest thereon at the rate per annum which is the
lesser of (i) the Lease Interest Rate or (ii) the highest rate permitted by law
shall be deemed Additional Rent hereunder and shall be payable to Landlord upon
demand as Additional Rent. Landlord shall use reasonable efforts to give prior
notice (which may be oral) of its performance, if reasonably feasible under the
circumstances. The performance of any such obligation by Landlord shall not
constitute a waiver of Tenant's default in failing to perform the same.

Inaction of Landlord shall never be considered as a waiver of any right accruing
to it pursuant to this Lease. Landlord, in making any payment hereby authorized:
(a) relating to Taxes, may do so according to any xxxx, statement or estimate,
without inquiry into the validity of any tax, assessment, sale, forfeiture, tax
lien or title or claim thereof, (b) for the discharge, compromise or settlement
of any lien, may do so without inquiry as to the validity or amount of any claim
for lien which may be asserted; or (c) in connection with the completion of
construction of improvements to the Premises or the repair, maintenance or the
payment of operating costs thereof, may do so in such amounts and to such
persons as Landlord reasonably may deem appropriate. Nothing contained herein
shall be construed to require Landlord to advance monies for any purpose.
Landlord shall not in any event be liable for inconvenience, annoyance,
disturbance, loss of business or other damage of Tenant or any other occupant of
the Premises or any part thereof, by reason of making repairs or the performance
of any work on the Premises or on account of bringing materials, supplies and
equipment into or through the Premises during the course thereof and the
obligations of Tenant under this Lease shall not thereby be affected in any
manner. In doing so, however, Landlord shall use reasonable efforts not to
interfere with the normal operation of the Premises. The term "EMERGENCY
SITUATION" shall mean a situation which has caused or is likely to cause bodily
injury to persons, contamination of or physical damage to the Premises or
adjoining property or economic liability or criminal jeopardy to Landlord.

ARTICLE XXIV
EXERCISE OF REMEDIES

SECTION 24.1. CUMULATIVE REMEDIES. No remedy contained herein or otherwise
conferred upon or reserved to Landlord, shall be considered exclusive of any
other remedy, but the same shall be cumulative and shall be in addition to every
other remedy given herein, now or hereafter existing at law or in equity or by
statute, and every power and remedy given by this Lease to Landlord may be
exercised from time to time and as often as occasion may arise or as may be
deemed expedient. No delay or omission of Landlord to exercise any right or
power arising from any default shall impair any such right or power or shall be
construed to be a waiver of any such default or an acquiescence therein.

SECTION 24.2. NO WAIVER. No waiver of any breach of any of the covenants
of this Lease shall be construed, taken or held to be a waiver of any other
breach, or a waiver, acquiescence in or consent to any further or succeeding
breach of the same covenant. The acceptance by Landlord of any payment of Rent
or other sums payable hereunder after the termination by Landlord of this Lease
or of Tenant's right to possession hereunder shall not, in the absence of
agreement in writing to the contrary by Landlord, be deemed to restore this
Lease or Tenant's right to possession hereunder, as the case may be, but shall
be construed as a payment on account and not in satisfaction of damages due from
Tenant to Landlord. Receipt of Rent by Landlord, with knowledge of any breach of
this Lease by Tenant or of any default by Tenant in the observance or
performance of any of the conditions or covenants of this Lease, shall not be
deemed to be a waiver of any provision of this Lease.

ARTICLE XXV
SUBORDINATION TO MORTGAGES

SECTION 25.1. SUBORDINATION. Landlord may execute and deliver a mortgage
or trust deed in the nature of a mortgage (both sometimes hereinafter referred
to as "Mortgage") against the Premises or any portion thereof. This Lease and
the rights of Tenant hereunder, shall automatically, and without the requirement
of the execution of any further documents, be and are hereby made expressly
subject and subordinate at all times to the lien of any Mortgage now or
hereafter encumbering any portion of the Improvements, and to all advances made
or hereafter to be made upon the security thereof, provided, however, the holder
of said Mortgage agrees in writing not to disturb the rights of Tenant under
this Lease so long as Tenant is not in default hereunder. Notwithstanding the
foregoing, Tenant agrees to execute and deliver such instruments subordinating
this Lease to the lien of any such Mortgage as may be requested in writing by
Landlord from time to time, provided that such instruments shall not materially
modify the terms of this Lease. Notwithstanding anything to the contrary
contained herein, any mortgagee under a Mortgage may, by notice in writing to
the Tenant, subordinate its Mortgage to this Lease.

SECTION 25.2. MORTGAGE PROTECTION. Tenant agrees to give the holder of any
Mortgage, by registered or certified mail, a copy of any notice of default
served upon the Landlord by Tenant, provided that prior to such notice Tenant
has received notice (by way of service on Tenant of a copy of an assignment of
rents and leases, or otherwise) of the address of such mortgagee and containing
a request therefor. Tenant further agrees that if Landlord shall have failed to
cure such default within the time provided for in this Lease and such default
does not materially adversely affect the habitability of the Premises, then said
mortgagee shall have an additional thirty (30) days after receipt of notice
thereof within which to cure such default or, if such default cannot be cured
within that time, then such additional time as may be necessary, if, within such
thirty (30) days, any mortgagee has commenced and is diligently pursuing the
remedies necessary to cure such default (including but not limited to
commencement of foreclosure proceedings, if necessary to effect such cure). Such
period of time shall be extended by any period within which such mortgagee is
prevented from commencing or pursuing such foreclosure proceedings by reason of
Landlord's bankruptcy. Until the time allowed as aforesaid for said mortgagee to
cure such defaults has expired without cure, Tenant shall have no right to, and
shall not, terminate this Lease on account of default. This Lease may not be
modified or amended so as to reduce the Rent or shorten the Term, or so as to
adversely affect in any other respect to any material extent the rights of the
Landlord, nor shall this Lease be cancelled or surrendered, without the prior
written consent, in each instance, of the mortgagee.

ARTICLE XXVI
INDEMNITY AND WAIVER

SECTION 26.1. INDEMNITY. Tenant shall not do or permit any act or thing to
be done or omit to do any act or thing upon the Premises which may subject
Landlord to any liability or responsibility for injury, damage to persons or
property, or to any liability by reason of any violation of applicable laws and
shall exercise such control over the Premises so as to fully protect Landlord
against any such liability. Tenant shall defend, indemnify and save Landlord,

and any official, agent, beneficiary, contractor, director, employee, lessor,
mortgagee, officer, parent, partner, shareholder and trustee of Landlord (each
an "INDEMNIFIED PARTY") representatives, successors and assigns harmless from
and against any and all liabilities, suits, judgments, settlements, obligations,
fines, damages, penalties, claims, costs, charges and expenses, including,
without limitation, engineers', architects' and attorneys' fees, court costs and
disbursements, which may be imposed upon or incurred by or asserted against any
Indemnified Party by reason of any of the following occurring during or after
(but attributable to a period of time falling within) the Term:

(a) any demolition or razing or construction of any
improvements or any other work or thing done in, on or about the Premises
or any part thereof by Tenant or any member of the Tenant Group (defined
below), including any claim that such work constitutes "public works";

(b) any use, nonuse, possession, occupation, alteration,
repair, condition, operation, maintenance or management of the Premises or
any part thereof or of any tunnel, creek, ditch, detention area, sidewalk,
curb or vault adjacent thereto by Tenant or any member of the Tenant
Group;

(d) any accident, injury (including death) or damage to any
person or property occurring in, on or about the Premises or any part
thereof or in, on or about any tunnel, creek, ditch, detention area,
sidewalk, curb or vault adjacent thereto as a result of the act or neglect
of Tenant or any member of the Tenant Group;

(e) any failure to perform or comply with any of the
covenants, agreements, terms or conditions in this Lease on Tenant's part
to be performed or complied with (other than the payment of money);

(f) any lien or claim which may be alleged to have arisen
against or on the Premises, or any lien or, claim which may be alleged to
have arisen out of this Lease and created or permitted to be created by
Tenant or any member of the Tenant Group against any assets of Landlord,
or any liability which may be asserted against Landlord with respect
thereto;

(g) any failure on the part of Tenant to keep, observe and
perform any of the terms, covenants, agreements, provisions, conditions or
limitations contained in the contracts and agreements affecting the
Premises on Tenant's part to be kept, observed or performed; and

(h) any contest permitted pursuant to the provisions of this
Lease.

No agreement or covenant of Tenant in this Section 26.1 shall be deemed to
exempt Landlord from, and Tenant's obligations under this Section 26.1 shall not
include liability or

damages for injury to persons or damage to property caused by or resulting from
the negligence of Landlord, its agents or employees, in the operation or
maintenance of the Project.

The obligations of Tenant under this Section 26.1 shall not be affected in
any way by the absence in any case of covering insurance or by the failure or
refusal of any insurance carrier to perform any obligation on its part under
insurance policies affecting the Premises or any part thereof.

SECTION 26.2. WAIVER OF CLAIMS. Except for the negligence of Landlord
and/or Landlord's agents, Tenant waives all claims it may have against Landlord
and Landlord's agents for damage or injury to person or property sustained by
Tenant or any persons claiming through Tenant or by any occupant of the
Premises, or by any other person, resulting from any part of the Premises

SECTION 34.5. RELATIONSHIP OF PARTIES. Nothing contained herein shall be
deemed or construed by the parties hereto, nor by any third party, as creating
the relationship of principal and agent or of partnership, or of joint venture
by the parties hereto, it being understood and agreed that no provision
contained in this Lease nor any acts of the parties hereto shall be deemed to
create any relationship other than the relationship of Landlord and Tenant.

SECTION 34.6. BROKERAGE. Tenant warrants that it has no dealings with any
real estate broker or agent in connection with this lease other than Landlord's
Broker and Tenant's Broker, and Tenant covenants to pay, hold harmless and

by Landlord of a lesser amount than the monthly rent herein stipulated and
additional rent shall be deemed to be other than on account of the earliest

Landlord's right to recover the balance of such rent or pursue any other remedy
in this Lease provided.

SECTION 34.8. JOINT EFFORT. The preparation of this Lease has been a joint

SECTION 34.11. LANDLORD'S CONSENT. Landlord's granting of any consent

without Landlord's consent required under this Lease, shall not be deemed a
waiver by Landlord of its rights to require such consent for any further similar
act by Tenant. No waiver by Landlord of any other breach of the covenants of
this Lease shall be construed, taken or held to be a waiver of any other breach
or to be a waiver, acquiescence in or consent to any further or succeeding

and no breach thereof, shall be waived, altered or modified except by a written
instrument executed by Landlord.

contrary herein contained, there shall be absolutely no personal liability
asserted or enforceable against Landlord or on any persons, firms or entities
who constitute Landlord with respect to any of the terms, covenants, conditions
and provisions of this Lease, and Tenant shall, subject to the rights of any
mortgagee, look solely to the interest of Landlord, its successors and assigns
in the, Premises for the satisfaction of each and every remedy of Tenant in the
event of default by Landlord hereunder; such exculpation of personal liability
is absolute and without any exception whatsoever. If the entity constituting

such partner shall not be deemed an asset or property of said partnership.
Notwithstanding anything in this Lease to the contrary, with respect to any
provision of this

Lease which requires Landlord's consent or approval, Tenant shall not be
entitled to make, nor shall Tenant make, any claim for (and Tenant hereby waives
any claim for) money damages as a result of any claim by Tenant that Landlord
has unreasonably withheld or unreasonably delayed any consent or approval, but
Tenant's sole remedy shall be an action or proceeding to enforce such provision,
or for specific performance, injunction or declaratory judgment.

concession or payment from Landlord for the improvement thereof.

Option, then Landlord and Tenant shall mutually execute and deliver an amendment

Term of this Lease. Tenant shall be responsible for all increases in Taxes based
upon Tenant's occupancy of the Premises. After the expiration of the Renewal
Term hereof, Tenant hereby agrees to reprorate Taxes. In the event of any
increase in Taxes from the Taxes reflected on the proration made upon the

RIGHT OF FIRST REFUSAL TO PURCHASE

SECTION 36.1. RIGHT OF FIRST REFUSAL TO PURCHASE. Landlord agrees that if,
at any time during the term of this Lease, Landlord receives an offer to
purchase the Premises, Tenant shall have the first right and option to purchase

property sale, (ii) Landlord determines to sell or transfer the Premises
to a Landlord Successor or Landlord Affiliate (as such terms are

agreement between Landlord and Tenant. If Tenant does not give Landlord
notice in writing within said twenty-one (21) -day period that Tenant
intends' to exercise its rights hereunder, then Landlord shall be free to
sell the Premises on the terms and conditions set forth in the offer
submitted to Tenant and in such event (i) Tenant's rights hereunder shall
terminate, and (ii) within five (5) days after the request of Landlord,
Tenant shall acknowledge in writing that it has not exercised its right of

bona fide offers.

ARTICLE XXXVII
LANDLORD'S WORK

SECTION 37.1. LANDLORD'S WORK.

(a) Landlord hereby agrees, at Landlord's sole cost and
expense, to perform the work described in EXHIBIT "C", which is attached
hereto and made a part hereof, to the Premises (hereinafter collectively
referred to as "Landlord's Work"). All of Landlord's Work shall be
completed in a good and workmanlike manner in compliance with all
applicable codes and regulations.

(b) When Landlord's Work is "substantially complete" (as
hereinafter defined), then Landlord shall so notify Tenant. It is
acknowledged between the parties that the Premises shall be deemed
substantially complete at such time as Landlord has substantially
completed Landlord's Work, notwithstanding Landlord may not have completed
any extra work requested by Tenant. Upon such notification, Tenant shall
promptly (and not later than two (2) business days after the date of
Landlord's said notice) inspect the Premises and furnish to Landlord a
written statement that, with the exception of certain specified and
enumerated items (hereinafter referred to as the "Punch List"), the
Premises are substantially complete. At the request of Landlord, from time
to time thereafter, Tenant shall, upon completion of items previously
listed on a Punch List, promptly furnish to Landlord a revised Punch List
acknowledging completion of said item. Landlord hereby agrees to use
reasonable efforts to complete all Punch List items within thirty (30)
days of the date the Premises is substantially complete, subject to
extension due to delays caused by Tenant, its agents or employees or
customary "force majeure" conditions. Provided Punch List items do not
materially impair Tenant's use or occupancy of the Premises, then, in such
event, the date on which the Premises are substantially complete is
referred to herein as the "Completion Date"; provided, however, to the
extent the Completion Date has not occurred as of the date reasonably
anticipated by Landlord as the Completion Date ("Anticipated Date") due to
delays caused by Tenant, the Completion Date shall be deemed to have
occurred on the Anticipated Date. Tenant shall absolutely take possession
of the Premises on the Commencement Date.

(c) In addition, Landlord shall fill all cracks, seal coat and
restripe the parking lot upon the Completion Date, subject to delays
caused by weather conditions and acts of God, but in no event later than
June 30, 2000.

(d) Tenant may propose one or more changes to the Plans for
Landlord's Work ("Plans Revisions") to Landlord any time before the
Completion Date, subject to the approval of Landlord and the Village of
Mundelein. As promptly as reasonably practicable after the receipt and
approval thereof, Landlord shall provide Tenant with a written estimate of
the Tenant Delay in the Completion Date and the amount of the additional
cost to complete the Landlord's Work which will result from such Plans
Revisions (whether hard costs or soft costs), which costs shall be: (i)
the cost of all materials, supplies and labor used or supplied in making
the proposed change, including general conditions and any contractor's
fees (which general conditions and contractor's fees shall be fifteen
percent (15%) of such costs); (ii) any architect and engineer fees; (iii)
soft costs; (iv) interest and carrying charges; and (v) fees and expenses
of architects, engineers and other third party consultants in connection
with review or approval of the Plans Revisions. If Tenant fails to approve
any of the Plans Revisions and associated estimate within five (5) days
after delivery of the same, Tenant shall be deemed to have abandoned its
request for such changes, and the Landlord's Work shall be constructed in
accordance with the then existing plans. If Tenant approves the Plans
Revisions and associated estimate within said five (5)-day period by
signing and returning a copy of Landlord's estimate, Landlord shall cause
the Landlord's Work to be constructed in accordance with the Plans
Revisions. Tenant shall pay Landlord the amount of such additional costs
within five (5) days after Landlord submits to Tenant a xxxx for such
additional costs prior to the time Landlord commences to make any changes.
In no event shall Landlord have any obligation to commence any work
relating to such changes until Landlord has been paid the cost of the
estimate in full and in the event that the additional costs are not paid
within said five (5) day period, Tenant shall be deemed to have abandoned
its request for such changes and the Landlord's Work shall be constructed
in accordance with the then existing plans. Unless requested in writing by
Tenant to the contrary, Landlord shall continue with construction of the
Landlord's Work according to the then existing plans during the pendency
of any proposed Plans Revisions until such change and cost estimate are
approved by Landlord and Tenant as provided above. Any halt in
construction requested in writing by Tenant shall constitute a Tenant
Delay hereunder. If Tenant requests a Plans Revisions pursuant to this
Section 37.1(d), and Tenant does not ultimately approve of the resulting
Plans Revisions or cost estimates, Tenant shall promptly reimburse
Landlord, as Additional Rent, for any reasonable costs and expenses
resulting from such requested changes incurred by Landlord.
