                                   MAINTENANCE

         All maintenance and cleaning of the Premises, but excluding any

                                  ARTICLE XII
                            REAL ESTATE TAX INCREASE

         A. For the purpose of this Article the following terms shall have the
following meanings: "lease year" shall mean the twelve-month period commencing
on the term commencement date, and each twelve-month period thereafter; "real
estate taxes" shall mean any and all amounts which become due and payable during
a lease year in respect of taxes and assessments, special or otherwise, imposed
upon the Building and the lot upon which it is located; "tax base" shall mean
the real estate taxes due and payable for the fiscal year from July 1, 1997 to
June 30, 1998. If real estate taxes applicable to any lease year are greater
than the tax base, the Tenant shall pay as additional rent for such lease year a
sum equal to 2.7% of the amount by which real estate taxes are greater than the
tax base (hereinafter called "Tenant's tax payment"). In the event real estate
taxes applicable to a lease year are greater than the tax base, the Landlord may
give the Tenant, within ninety (90) days after the end of such lease year, or
within ninety (90) days after Landlord is notified of such tax, notice of
Tenant's tax payment for such lease year; provided, however, that if this lease
expires or is terminated during such lease year, Tenant's tax payment shall be
limited to an amount equal to Tenant's tax payment for such lease year
apportioned as of the date of such expiration or termination, and the Tenant
shall make payment of Tenant's tax payment or of the same as apportioned within
thirty (30) days after the giving of such notice, notwithstanding the fact that
this lease has expired or has been terminated prior to the time of the giving of
such notice. In the event the Landlord shall receive any refund as a result of a
reduction in real estate taxes for any lease year after the first lease year

                                       5
<PAGE>
and a Tenant's tax payment for such lease year has been made by the Tenant, the
Landlord shall remit to the Tenant a sum equal to 2.7% of the refund received by
the Landlord for such lease year, after deducting from such refund all expenses
incurred by the Landlord in connection with obtaining the same, including
attorneys' fees. At Landlord's option, any additional rent attributable to an
increase in real estate taxes, or any decrease in rent due to a decrease in real
estate taxes, shall be payable by Tenant, or credited to Tenant, as the case may
be, on a monthly basis allocated evenly over the number of months in the lease
year, or balance of the lease year if such increase or decrease shall be
effective during the middle of a lease year.

         B. Tenant shall pay before delinquency all taxes, assessments, license
fees, and other charges which are levied against Tenant's alterations and
fixtures and which become payable during the term hereof. If any such
alterations or fixtures are assessed with Landlord's real property, Tenant shall
pay Landlord the taxes attributable to Tenant within thirty (30) days after
receipt of a written statement setting forth the applicable taxes.

         C. During the first and last years of the term hereof, all such taxes
and assessments which shall become payable during each of the calendar, fiscal,
tax or assessments years, as applicable, shall be ratably adjusted on a per diem
basis (based on the area that the Premises bears to the Building) between
Landlord and Tenant in accordance with the respective portions of such calendar,
fiscal, tax or assessment year.

                                  ARTICLE XIII
                                     DAMAGE

         The Landlord shall not be liable for damage to any proper or injury to
any person at any time in the Premises or Building by reason of any action of
the elements or arising from water, wind, rain, smoke, steam or electricity
which may leak into, or issue or flow from any part of the Building. The
Landlord shall not be responsible for any latent defect or change of conditions
in the Premises resulting in damage to the same or to the property or persons
therein unless due to the negligence of the Landlord, its agents, servants or
employees.

                                  ARTICLE XIV
            ASSIGNMENT AND SUBLETTING; LANDLORD'S OPTION TO TERMINATE

         1. Neither the Tenant nor the legal representative of the Tenant shall
assign, transfer or mortgage this lease or any interest therein or let or sublet
the Premises or any part thereof or permit the Premises or any part thereof to
be used by others without the prior written consent of the Landlord in each
instance, which consent may be withheld by Landlord at its sole discretion.

                                       6
<PAGE>
In the event such consent be given, the same shall be deemed to relate solely to
the particular assignment, transfer, mortgage, sublease or permission referred
to in such consent. Consent shall not be given for a restaurant, or
manufacturing business.

         2. In lieu of granting its consent to a subleasing or assignment of
this lease, Landlord may, at any time when its consent is requested to an
assignment or subleasing, and within fifteen (15) days of the making of such
request, notify Tenant that this lease is terminated. Such termination shall
take place no less than thirty (30) and no more than sixty (60) days after the
date of such notice of termination by Landlord. In the event of such
termination, this lease shall upon the date so selected by Landlord terminate as
fully and completely as if the term hereof had expired.

                                   ARTICLE XV
                                  SUBORDINATION

         This lease is and shall be subject and subordinate to all mortgages and
ground leases which may now or hereafter affect the Building of which the
Premises form a part, and to all renewals, modifications, consolidations,
replacements and extensions thereof, and, although this subordination provision
shall be deemed for all purposes to be automatic and effective without any
further instrument on the part of the Tenant, the Tenant shall execute any
further instrument requested by the Landlord to confirm such subordination.

                                  ARTICLE XVI
                                 ADDITIONAL RENT

         All amounts over and above the base rent payable by the Tenant to the
Landlord under the terms of this lease shall be deemed additional rent hereunder
and shall be payable to the Landlord upon demand, unless provision is made
herein for payment of such amount on a specific date or within a specific time,
and, in default of payment, may, at the Landlord's option, be added to and
become a part of any subsequent installment of base rent falling due, and the
Landlord shall have all the rights and remedies in the event of non-payment
thereof as in the case of the base rent.

                                  ARTICLE XVII
          CONDITIONAL LIMITATIONS; DEFAULT PROVISIONS WAIVERS BY TENANT

1. If, during the term of this lease, the Tenant shall (a) apply for, or consent
in writing to, the appointment of a receiver, trustee or liquidator of the
Tenant or of all or substantially all of its assets, or (b) file a voluntary
petition in bankruptcy, or admit in writing its

                                       7
<PAGE>
inability to pay its debts as they become due, or (c) make a general assignment
for the benefit of creditors, or (d) file a petition or an answer seeking
reorganization (other than a reorganization not involving the liabilities of the
Tenant) or arrangement with creditors, or take advantage of any insolvency law,
or (e) file an answer admitting the material allegations of a petition filed
against it in any bankruptcy, reorganization or insolvency proceeding, or, if an
order, judgment or decree shall be entered by any court of competent
jurisdiction on the application of a creditor adjudicating the Tenant a bankrupt
or insolvent, or approving a petition seeking reorganization of the Tenant
(other than a reorganization not involving the liabilities of the Tenant) or
appointment of a receiver, trustee or liquidator of the Tenant or, of all or
substantially all its assets, and such order, judgment or decree shall continue
uncontested and in effect for any period of sixty (60) consecutive days, the
Landlord may, at its option, give to the Tenant a notice of intention to end the
term of this lease at the expiration of five (5) days from the date of service
of such notice, and at the expiration of said five (5) days, the term of this
lease and all right, title and interest of the Tenant hereunder shall expire as
fully and completely as if that day were the date herein specifically fixed for
the expiration of the term, and the Tenant will then quit and surrender the
Property to the Landlord, but the Tenant shall remain liable as hereinafter
provided.

         2. If, during the term of this lease, (a) the Tenant shall default in
fulfilling any of the covenants of this lease (other than the covenants for the
payment of base rent and additional rent payable by the Tenant hereunder), or
(b) the Property shall be left vacant or unoccupied or be deserted for a period
of fifteen (15) days, or (c) this lease, without the prior written consent of
the Landlord shall be assigned or transferred in any manner or shall, by
operation of law, pass to or devolve upon any third party, the Landlord may give
to the Tenant notice of any such default or the happening of any event referred
to above and if at the expiration of thirty (30) days after the service of such
a notice the default or event upon which said notice was based shall continue to
exist, or in the case of a default which cannot with due diligence be cured
within a period of thirty (30) days, if the Tenant fails to proceed promptly
after the service of such notice and with all due diligence to cure the same and
thereafter to prosecute the curing of such default with all due diligence (it
being intended that in connection with a default not susceptible of being cured
with due diligence within thirty (30) days that the time of the 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), the Landlord may give to the Tenant a
notice of intention to end the term of this lease

                                       8
<PAGE>
at the expiration of five (5) days from the date of the service of such second
notice, and at the expiration of said five (5) days the term of this lease and
all right, title and interest of the Tenant hereunder shall expire as fully and
completely as if that day were the date herein specifically fixed for the
expiration of the term, and the Tenant will then quit and surrender the Property
to the Landlord, but the Tenant shall remain liable as hereinafter provided.

         3. If the Tenant shall default in the payment of the base rent or
additional rent, or any part of the same and such default shall continue for
three (3) days after notice thereof by the Landlord or if this lease shall
terminate as in subdivision 1 or subdivision 2 of this Article provided, the
Landlord or the Landlords agents and servants may immediately or at any time
thereafter re-enter the Property and remove all persons and all or any property
therefrom, either by summary dispossess proceedings or by any suitable action or
proceeding at law, or otherwise, without being liable to indictment, prosecution
or damages therefor, and repossess and enjoy the Property with all additions,
alterations and improvements. Upon the termination of this lease by reason of
the happening of any of the events herein above described in subdivision 1 or
subdivision 2 of this Article, or in the event of the termination of this lease
by summary dispossess proceedings or under any provisions of law now or at any
time hereafter in force, by reason of, or based upon, or arising out of a
default under or breach of this lease on the part of the Tenant, or upon the
Landlord recovering possession of the Property in the manner or in any of the
circumstances hereinbefore mentioned, or in any other manner or circumstances
whatsoever, whether with or without legal proceedings, by reason of or based
upon or arising out of a default under or breach of this lease on the part of
the Tenant, the Landlord may, at its option, at any time, and from time to time,
relet the Property or any part or parts thereof for the account of the Tenant or
otherwise on such terms as the Landlord may elect, including the granting of
concessions, and receive and collect the rents therefor, applying the same first
to the payment of such expenses as the Landlord may have incurred in recovering
possession of the Property, including legal expenses, and for putting the same
into good order or condition or preparing or altering the same for re-rental,
and expenses, commissions and charges paid, assumed, or incurred by the Landlord
in and about the reletting of the Property, and then to the fulfillment of the
covenants of the Tenant hereunder. Any such reletting herein provided for may be
for the remainder of the term of this lease or for a longer or shorter period.
In any such case and whether or not the Property or any part thereof be relet,
the Tenant shall pay to the Landlord

                                       9

<PAGE>
the base rent and additional rent required to be paid by the Tenant up to the
time of such termination of this lease, or of such recovery of possession of the
Property by the Landlord, as the case may be, and thereafter the Tenant
covenants and agrees, if required by the Landlord, to pay to the Landlord until
the end of the term of this lease as originally demised the equivalent of the
amount of all the base rent and additional rent reserved herein, less the net
avails of reletting, if any, and the same shall be due and payable by the Tenant
to the Landlord on the several rent days above specified, that is to say, upon
each of such rent days the Tenant shall pay to the Landlord the amount of the
deficiency then existing. In any such circumstances the Landlord shall have the
election, in place and stead of holding the Tenant so liable, forthwith to
recover against the Tenant as damages for loss of the bargain and not as a
penalty, an aggregate sum which, at the time of such termination of this lease,
or of such recovery of possession of the Property by the Landlord, as the case
may be, represents the then present worth of the excess, if any, of the
aggregate of the base rent and additional rent that would have accrued for the
balance of the term over the aggregate rental value of the Property for the
balance of such term, unless any statute or rule of law governing the proceeding
in which such damages are to be proven shall limit the amount allowed on such
claim, in which case the Landlord shall be entitled as and for liquidated
damages by reason of such breach and termination of this lease, the maximum
amount which may be allowed by or under such statute or rule of law. In
computing the additional rent that would have accrued for the balance of the
term, the annual amount of the additional rent shall be deemed to be an amount
equal to the average of the annual amounts paid by the Tenant pursuant to
Article XVI hereof for the three years preceding the year in which such
termination occurs, or for such lesser period of time as this lease may have
been in effect prior to such termination. Nothing herein contained shall limit
or prejudice the Landlord's right to prove and obtain as liquidated damages
arising out of such breach or termination the maximum amount allowed by any
statute or rule of law which may govern the proceedings in which such damages
are to be proved whether or not such an amount be greater, equal to, or less
than the amount of the excess of the base rent and additional rent over the
rental value referred to above.

         4. The Tenant hereby expressly waives the service of notice of
intention to re-enter as provided for in any statute, or to institute legal
proceedings to that end, and also waives any and all rights of redemption in
case the Tenant shall be dispossessed by a judgment or by warrant of any court
judge.

                                       10
<PAGE>
         The Tenant also waives any and all right to a trial by jury in any
matter arising out of or in connection with this lease or the right to assert a
counterclaim in any summary proceedings which may be instituted by the Landlord.
The terms "enter" and "re-enter", as used in this lease are not restricted to
their technical legal meaning. All of the covenants of the Tenant shall be
deemed and construed to be "conditions" as well as "covenants" as though the
words specifically expressing or importing covenants and conditions were used in
each separate instance. In the event any proceedings are brought against the
Tenant for non-payment of base rent or additional rent, or as a result of
termination of this lease, and whether or not such proceedings shall be
discontinued as a result of the Tenant paying such base rent or additional rent,
the Tenant will pay to the Landlord as a liquidated amount without necessity of
further liquidation or approval by the court, ten percent (10%) of the amount
claimed to be due from Tenant, if any, but in no ever/' less than $1,000.00, for
payment of Landlord's court costs, expenses, and attorneys' fees. Said amount
shall be due and payable upon the mere commencement by Landlord of said judicial

expiration shall not constitute a renewal hereof or provide Tenant with any
