with the beginning or end of the tax year.

         Section 3.03 - Installment Payment. Lessee shall have the right to
execute in the name of the Lessor and as its attorney in fact such agreement or
agreements or other instrument which may be required or permitted by law to

shall not be liable to pay any installments for taxes not due at the end of this
original or any renewed term after occupancy of the Lessee has closed.

         Section 3.04 - Unpaid Taxes. If Lessee fails to pay any such taxes,
assessments or other public charges which it is obligated to pay as provided in
this Article, before the same become delinquent, then and in such event, Lessor

contrary notwithstanding, Lessor agrees that Lessee shall have the right, at
Lessee's sole cost and expense, to contest the legality, validity, or the basis
of calculation, of any of the taxes, assessments or other public charges
provided to be paid by Lessee, but no such contest shall be carried on or
maintained by Lessee after such taxes, assessments or other public charges
become delinquent unless Lessee shall have duly paid the amount involved under
protest or shall procure and maintain a stay of all proceedings to enforce any
collection thereof and any forfeiture or sale of the Demised Premises, and shall
also provide for payment thereof together with all penalties, interest, cost and
expense by deposit of a sufficient sum of money or by a good and sufficient
undertaking as may be required by law to accomplish such stay. Lessor agrees
that it will, at the request of Lessee, execute or join in the execution of any
instrument or documents necessary in connection with any such contest except
bonds or undertakings. In the event any such contest is made by Lessee, Lessee
shall promptly, upon final determination thereof adversely to Lessee, pay and

improvements therein or thereto, in good order and condition, except for normal
wear and tear, damage done by casualty not covered by the provisions of the
usual fire and extended coverage insurance, or acts of the Lessor.

damage the Demised Premises or that might be a permanent attachment to the
Demised Premises without the written consent of Lessor. The consent of Lessor
shall not be unreasonably withheld. The costs of any such alterations or
improvements approved by Lessor shall be borne by the Lessee and shall remain
upon and be surrendered with the Demised Premises; provided, however, that any
trade fixtures installed by Lessee may be removed by Lessee at the expiration of
the term of this Lease, or of any renewal, provided that the Lessee is not in
default under the terms hereof and provided further that any damage occasioned
by any such removal shall be paid by Lessee.

         Section 3.08 - Fees and Commissions. Lessor and Lessee represent to
each other that neither party has engaged the services of a real estate broker
or agent in negotiating or consuming the closing of this Lease. Lessor and

services performed in connection with this lease.

         Section 3.09 - Indemnification of Lessor. Lessee covenants and agrees
that Lessor shall not be liable for any injuries or damages to persons,
entities, or property from any cause whatsoever by reason of the use,
occupation, control or enjoyment of the Demised Premises by Lessee, or any
person entering thereon for any reason or invited (other than Lessor or their
agents), suffered or permitted by Lessee to go or be thereon or holding under
Lessee at any time during the term of this lease, and Lessee will save and hold
harmless Lessor from and against any and all liability, penalties, damages,
expenses and judgments whatsoever on account of such injuries or damages. The
injuries and damages referred to in this paragraph shall include, without
limiting the generality of the preceding provisions, to injuries, damages and
mechanic's liens arising directly or indirectly out of any demolition, repairs,
restoration, reconstruction, changes, alterations and construction which Lessee

every nature and kind whatsoever of any governmental agency or authority
concerning the Demised Premises. It is expressly understood that the Lessee
shall have thirty (30) days or such time as said authorities shall accord, or

         Section 6.01 - Eminent Domain. If more than twenty-five percent (25%)
of the land area of the Demised Premises is taken under the power of eminent
domain (including any conveyance made in lieu thereof), and such taking shall
make the operation of Lessee's business on the Demised Premises impractical,
then Lessee shall have the right to terminate this lease by giving Lessor
written notice of such termination within thirty (30) days after such taking or
condemnation. If Lessee does not so elect to terminate this lease, the rental to
be paid by Lessee hereunder shall be equitably reduced in proportion to Lessee's
loss of the use of the Demised Premises. Any award or awards payable on account
of any taking or condemnation of all or part of the Demised Premises shall be
payable to Lessor.

         default, but only if the party in default has not remedied such default
         within the said thirty (30) days or if the party in default has not
         commenced such act or acts as shall be necessary to remedy the default
         and shall complete such act or acts promptly; or

         (b) terminate this lease for the nonpayment of rent at any time after
         the expiration of ten (10) days following written notice to Lessee of
         nonpayment of such rent (provided each default has not been cured); and

         (c) any termination of this lease under sub-paragraphs (a) and (b) of
         this Section 7.01 shall not prejudice Lessor's right to prosecute any
         other remedy which it may have for a breach of this lease or default
         hereunder.

         Section 7.02 - Event of Default Defined. Each of the following shall be

                  reorganization, arrangement, composition, readjustment,
                  liquidation, dissolution or other relief of the same or
                  different kind under any provision of the Bankruptcy Act;

                  (3) Adjudication of Lessee as a bankrupt or insolvent or

                  or part thereof upon execution, attachment or other process of
                  law or equity (except pursuant to a valid assignment or
                  sublease pursuant to Article VIII).

         Section 7.03 - Repossession. Upon termination of this lease as
hereinabove provided, or pursuant to statute, or by summary proceedings or

any part of the Demised Premises, if it has not theretofore done so, and resume
possession either by summary proceedings, or by action at law or in equity or by
entry or otherwise as the Lessor may determine, and shall not be liable in
trespass or for any damages to Lessee or any other person. In no event shall

Lessor including reasonable attorney fees for such purpose, with interest
thereon at the rate of ten percent (10%) per annum plus an additional service
fee of two percent (2%) from the date of payment thereof by Lessor.


<PAGE>   10

         Section 7.06 - Non-Exclusive Effect. The default provisions in this
Article VII shall not operate to exclude, override or limit any other right or
remedy provided in this lease, but shall be read in conjunction with the other
provisions hereof as supplementary thereto, and any election by the party for
whose benefit a particular provision operates, as communicated in any notice to
the other party, shall be conclusive as to the provision under which the former
is proceeding. Unless otherwise specified in such notice, however, any such
election shall not act as a waiver of the right to proceed under any other
provision at any other time with respect to the same or any other breach,
default, omission or failure of performance which may be the subject of the

                          TRANSFER OF LESSOR'S INTEREST

         Section 9.01 - Transfer of Lessor's Interest. In the event of the sale,
assignment or transfer by Lessor of its interest in the Demised Premises or in
this lease (other than a collateral assignment to secure a debt of Lessor) to a
successor in interest who expressly assumes the obligations of Lessor hereunder,
Lessor shall thereupon be released or discharged from all of its covenants and
obligations hereunder, except such obligations as shall have accrued prior to
any such sale, assignment or transfer; and Lessee agrees to look solely to such
successor in interest of Lessor for performance of such obligations. Lessor's
assignment of the lease or of any or all of its rights herein shall in no manner
affect Lessee's obligations hereunder. Lessee shall thereafter attorn and look
to such assignee, as Lessor, provided Lessee has first received written notice
of such assignment of Lessor's interest.

                                    ARTICLE X

                             SUPPLEMENTARY AGREEMENT

         Section 10.01 - Agreement as to Modification. Lessee agrees at any time
and from time to time upon not less than ten (10) days prior written request by
Lessor, to execute, acknowledge and deliver to Lessor, and Lessor agrees at any
time and from time to time, upon not less than ten (10) days prior written
request by Lessee, to execute, acknowledge and deliver to Lessee a statement in
writing certifying that this lease is unmodified and in full force and effect
(or if there have been mutually agreed upon modifications that the same is in
full force and effect, as modified, and stating the modifications), and the
dates to which the fixed rent and other charges have been paid in advance, if
any, and whether or not there is any existing default, other than on any
existing mortgage, by Lessee with respect to any sums of money required to be
paid by Lessee under the terms of this lease, or notice of default served by
Lessor, it being intended that any such statement delivered pursuant to this
paragraph may be relied upon by any prospective purchaser of the fee or
leasehold estate or by any prospective or existing mortgagee or assignee of any
mortgage upon the leasehold estate, or by any prospective assignee or subtenant
of the leasehold estate. If any such certification by Lessor shall allege
non-performance by Lessee, the nature and extent of such non-performance shall,
insofar as actually known by Lessor, be summarized therein. In the event that
either party shall fail to execute, acknowledge and deliver to the other each
statement prior to the expiration of said ten (10) day period, it shall be
conclusively presumed a certification that this lease is unmodified and in full
force and effect, that all rental has been paid to date and that there is no
existing default.

         Section 10.02 - Acknowledgment of Rent. The Lessor within ten (10)
days, upon request of the Lessee or any holder of a mortgage on the fee or
leasehold interest herein demised, will furnish a written statement duly
acknowledging the amount of rent and additional rent due, if any.


<PAGE>   12

         Section 10.03 - Easements. Lessor covenants and agrees that it will
execute any and all instruments that may be required of the Lessor in connection
with the granting of easements for installation of water, gas, steam,
electricity, telephone, sewage and storm drainage of the various utility
companies affecting any street, opened or proposed, on any part of the Demised
Premises.

         Section 10.04 - Notice of Default. Wherever in this lease the Lessor is
given the right to pay any sum of money or perform any act which, by the terms
of this lease, are to be performed by the Lessee, Lessor agrees that it will not
so pay or perform until it has given Lessee thirty (30) days written notice of
its intent so to do and the Lessee at the expiration of such thirty (30) day
period has not made such payment or commenced and is diligently prosecuting such
performance; provided, however, that such period shall not exceed any other
period of notification specifically set forth herein relating to specific acts
of the parties hereto, it being specifically understood that this thirty (30)
day period notice shall not control or override the other notice requirements
specifically set forth in the lease agreement.
