<PAGE>


the Land or for providing any off-site improvements, roads, or facilities
whatsoever and Tenant hereby accepts the Leased Premises "AS-IS, WHERE-IS."

Landlord does not consent, and has not by the execution and delivery of this
Lease consented, to the imposition of any liens upon the Landlord's interest in
the Leased Premises by any party whomsoever. Tenant covenants and agrees to

mechanic's lien is filed, Tenant may, within twenty (20) days after receipt of
such notice, bond off or make other suitable arrangements reasonably acceptable
to Landlord relative to such lien in order to contest the same, so long as such
bond fully protects Landlord and the Leased Premises from such claim.

15. Condemnation.

         a. Definitions. Wherever used in this Paragraph, the following word
shall have the definitions and meaning hereinafter set forth;

                  i. "Condemnation proceedings" means any action or proceeding
         brought for the purpose of any taking of the fee, material right of way
         or other interest in the Leased Premises or any part thereof (or direct
         access thereto) by competent authority as a result of the exercise of
         the power of eminent domain, including a voluntary sale to such
         authority either under threat of condemnation or while such action or
         proceeding is pending.

                  ii. "Taking" or "taken" means the event and date of vesting of
         title to the fee of the Leased Premises or any part thereof pursuant to
         the condemnation proceedings.

         b. Complete Taking. If all or substantially all of the Leased Premises
shall be taken in condemnation proceedings, either Tenant or Landlord shall have
the right to terminate this Lease as of the date of such taking and the transfer
of possession. As of the date of such termination, Landlord shall give Tenant a
proportionate refund and of any rent paid in advance, and this Lease shall
terminate. "Substantially all" of the Leased Premises shall be deemed taken (i)
if all of the Building is taken, or (ii) if direct access to the Leased Premises
is taken by the elimination of direct access to the adjacent public highway,
that is not replaced by alternate access.

         c. Award for Complete Taking. All compensation awarded for any taking
of the Lease Premises (including, without limitation the Improvements) or any
interest in either shall belong to and be the property of the Landlord and
Tenant hereby assigns to Landlord all its right, title and interest in any such
award, except to the extent that this Lease is terminated and Tenant files a
claim, at its sole cost and expense, as delineated below and the condemning
authorities specifically award to Tenant or specifically allocate a portion of
the award to Tenant as of the effective date of the taking, including Tenant's
relocation expenses and lost good will, provided,



                                       10


<PAGE>

however, the filing of such claim by Tenant or allocation by the condemning
authorities to Tenant does not adversely affect or diminish the award which
would otherwise have been received by Landlord had Tenant not filed such a claim
and received such award. Subject to the foregoing, in the event all or any part
of the Premises is condemned or sought to be condemned, Tenant shall be
entitled, in its sole discretion to assert a claim to or for one or more of the
following: (a) for compensation for the value of Tenant's leasehold interest
which may include a claim for Tenant's costs of removal and relocation,
unreimbursed expenses incurred by Tenant to install tenant improvements at its
new location and the economic loss incurred by Tenant due to higher rental
rates, shorter term, CAM fees, etc. incurred under the replacement lease; and
(b) for recovery from the condemner to the maximum extent otherwise allowable by
law. "Condemned" and "condemnation" shall be construed to include any transfer
of possession, title or right relating to the Premises in favor of or for the
benefit of any entity having the power of eminent domain, including, but not
limited to, sale or lease. No right of termination set forth anywhere in this
Lease may be exercised by or for the benefit of any entity having the payer of
eminent domain.

         d. Less than Complete Taking. If less than substantially all of the
Leased Premises is taken but more than 15% of the gross rentable square feet
thereof or more than 15% of the parking space comprising a portion of the Leased
Premises, then (1) Tenant, at its election shall have the right to terminated
this Lease and will notify Landlord of its election within thirty (30) days of
its election; (ii) if Tenant elects to continue the Lease. Tenant shall commence
and proceed with reasonable diligence to repair and reconstruct the remaining
Improvements on the Leased Premises to a complete architectural unit, to the
extent the condemnation award is available therefore, and (iii) the Base Rent
and related charges payable by Tenant hereunder shall continue with an equitable
reduction and modification, to reflect the loss of any part or functionality of
the Building or the parking area. The award in condemnation proceedings for any
partial taking where repair or reconnection is undertaken shall be apportioned
and paid in the following order of priority:

         First - There shall be paid any and all reasonable expenses, charges
and fees, including reasonable counsel fees, in collecting the awards.

         Second - The proceeds of the awards shall next be used as a fund for
the restoration and repair of the Building to a complete architectural unit.
Said proceeds shall be held by Landlord, and shall be paid out from time to time
to persons furnishing labor or materials, or both, including architects' fees
and contractors' compensation in such restoration work on vouchers approved by a
licensed architect or engineer approved by Landlord and employed by Tenant to
supervise the work.

         Third - The balance of the award shall be equitably allocated between
Landlord and Tenant . If the proceeds are not sufficient far the repair and
restoration of the Improvements, then Landlord and Tenant shall attempt in good
faith to agree on a reduced scope of restoration which can be funded through the
balance of the award. If the parties are unable to so agree, then either Tenant
or Landlord shall have the right, upon notice to the other within twenty (20)
days following receipt of confirmation of such deficiency, to cancel and
terminate this Lease and the rights and obligations of Tenant hereunder. Upon
receipt of such notice, Tenant shall have a reasonable time to surrender and
deliver possession of the Leased premises to Landlord in


                                       11

<PAGE>


accordance with the terms hereof. In such event, Tenant shall only be entitled
to a condemnation award as provided in paragraph 15(c) hereof. Notwithstanding
the foregoing, the party receiving the notice shall have the right to void such
notice of cancellation by (i) forwarding notice to such party within five (5)
days of receipt of the notice, of such party's intent to provide such deficiency
in funds, and (ii), in the case of Tenant, paying such amount to Landlord for
use solely for the restoration of the Improvements in accordance with this
Paragraph 15.

         e. Responsible Party. Both Landlord and Tenant shall have
responsibility for dealing with the condemning authority in any condemnation
proceedings relative to their respective interests in the Leased Premises.

expense the following insurance on the Leased Premises:

         Policies for such insurance shall be for the mutual benefit of
         Landlord, Tenant and any Lender.

                  iii. Tenant shall not be required to obtain business
         interruption insurance but shall be required to reimburse Landlord in
         an amount not to exceed $750 per year for the cost to Landlord of
         maintaining insurance covering loss of income its the event of casualty

         which may be caused by them.

shall be for a term of not less than twelve months, (ii) shall be in amounts
sufficient at all times to satisfy any coinsurance requirements thereof, and
(iii) shall (except for the worker's


                                       12

<PAGE>

respective interests may appear. If said insurance or any part thereof shall
expire, be withdrawn, become void by breach of any condition thereof by Tenant
or become void or unsafe by reason of the failure or impairment of the capital
of any insurer, or if for any other reasonable cause said insurance shall become
unsatisfactory to Landlord, Tenant shall immediately obtain new or additional

notwithstanding (1) any act or omission of Tenant which might, absent such
provision, result in a forfeiture of all or a part of such insurance payment, or

premiums for the insurance required by this Paragraph 16, shall renew or replace
each policy, and shall deliver to Landlord such renewal or replacement policy
and evidence of the payment of the full premium therefor at least ten (10) days

comply with any of the foregoing requirements, Landlord shall be entitled to
procure such insurance, at Tenant's sole cost and expense. Any sums expended by
Landlord in procuring such insurance shall be repaid by Tenant within thirty
(30) days after written demand therefor by Landlord.

         e. Blanket Policies. Anything in this Paragraph 16 to the contrary
notwithstanding, any insurance which Tenant is required to obtain pursuant to

there shall be an] equitable abatement of the Base Rent but in no event for a
period in excess of one year from the date of the last payment of Base Rent


                                       13

<PAGE>

as Tenant is not in default hereunder, shall be made available to Tenant in such
commercially reasonable manner as Landlord, Tenant and Lender may agree, and
Tenant, as required in Paragraph 12(a), shall commence and diligently continue
to restore the Land and Improvements as nearly as possible to their value,
condition and character immediately prior to such damage, in accordance with the
provisions of clauses (i) through (iv) of Paragraph 17(a), except as provided in
paragraph 16(h) to the contrary. Tenant, to the extent of Net Proceeds, shall
promptly repair or replace such Improvements and Equipment, in accordance with
the provisions of Paragraph 11(a).

         h. Termination Right. If the Leased Premises are at any time damaged to
the extent of fifty percent (50%) or more of the value thereof or the nature and
extent of the damage makes it impractical for Tenant to conduct its prior
business activity at the Leased Premises, or if damaged to the extent of 50
percent (50%) or more of the value thereof within such time as less than one (1)
year remains in the Term or any exercised Option Term, Tenant shall have no
obligation to restore the Leased Premises if it shall give notice to Landlord of
its intent not to so restore not later than sixty (60) days after such casualty,
but all Net Proceeds due in connection with such casualty, plus any deductible,
in an amount sufficient to restore the Leased Premises to a complete operational
architectural unit shall be delivered to Landlord by the insurance company
and/or Tenant, at which time the Term of this Lease shall terminate upon such
payment and payment of all sums otherwise due and payable by Tenant hereunder
through the Base Rent Payment Date stated in Tenant's notice (the "Casualty
Termination Date). If the Leased Premises suffers damage to any extent less than
fifty percent (50%) of the value thereof or if Tenant does not elect to
terminate this Lease, the Base Rent payable by Tenant hereunder shall be
proportionately abated but in no event for a period in excess of one year from
the date of the last payment of Base Rent prior to the date of such casualty.

                  i. Extension of Casualty Termination Date. Notwithstanding
         anything to the contrary hereinabove contained, if, prior to the
         Casualty Termination Date, Landlord shall not have received the full
         amount of the Net Proceeds payable by reason of the Casualty, plus any
         deductible, the Casualty Termination Date shall automatically be
         extended to the date of receipt by Landlord of the full amount of the
         Net Proceeds.

                  ii. Waiver of Subrogation. Landlord and Tenant hereby agree
         that to the extent that a loss at the Leased Premises is covered by
         insurance, including any deductible, they each hereby waive any and all
         rights of subrogation against the other for any loss or damage; and
         each party's aforesaid policies of insurance shall contain appropriate
         provisions recognizing this mutual release and waiving all rights of
         subrogation by the respective insurance carriers.

17. Restoration.

         a. Regiment for Disbursement of Net Proceeds. In the event that Net
Proceeds are made available to Tenant for the restoration of any of the Land or
Improvements, Tenant shall commence and complete such restoration as soon as

with the following conditions.

<PAGE>


                  i. Prior to commencement of restoration, the architects,
         contracts, contractors, and plans and specifications for the
         restoration shall have been approved by Landlord. which approval shall
         not be unreasonably withheld;

                  ii. disbursements shall be made from time to time in as mount
         not exceeding the cost of the work completed since the last
         disbursement upon receipt of (1) an architect's certificate of the
         performance of the work to date in a good and workmanlike manner in
         accordance with the contracts, plans and specifications, (2) waivers of
         liens, (3) contractors' and subcontractors' sworn statements (as to the
         final disbursement only), (4) a satisfactory bring down of title
         insurance (as to the final disbursement only), and (5) at the time of
         the final disbursement, evidence of issuance of a certificate of
         occupancy (or availability of the same subject to completion of
         "punchlist" and minor items) and compliance with Legal Requirements;

                  iii. each request for disbursement shall be accompanied by a
         certificate of Tenant, signed by the President or any Vice President of
         tenant, describing the work for which payment is requested, stating the
         cost incurred in connection therewith and stating that Tenant has not
         previously received payment for such work and the certificate to be
         delivered by Tenant upon completion of the work shall, in addition,
         state that the work has been completed and complies with the applicable
         requirements of this Lease;

                  iv. the restoration fund shall be kept in a separate
         interest-bearing account by Tenant; and

         In addition, prior to commencement of casualty restoration and at any
time during casualty restoration, if the estimated cost of restoration, as
reasonably determined by Landlord, exceeds the amount of the Net Proceeds
available for such restoration, the amount of such excess shall be paid by
Landlord to be added to the restoration fund. Any sum in the restoration fund
added by Landlord which remains in the restoration fund upon the completion of
restoration shall be returned to Landlord. For purposes of determining the
source of funds with respect to the disposition of funds retraining after the
completion of restoration, the Net Proceeds shall be deemed to be disbursed
prior to any amount added by Landlord.

         b. Excess Net Proceeds. In the event that there are funds not added by
Landlord remaining undisbursed upon completion of restoration and full payment
therefor (the "Remaining Sum") then such sum shall be credited to Base Rent
subsequently accruing hereunder.

18. Subordination to Financing. Tenant agrees that this Lease shall at all times
be subject and subordinate to the lien of any Mortgage, and Tenant agrees, upon
demand, without cost, to execute instruments as may be reasonably required to
further effectuate or confirm such subordination, including the Subordination,
Non-Disturbance and Attornment Agreement and Estoppel Certificate attached as
Exhibit "B," provided, however, as a condition to this subordination, so long as
Tenant shall faithfully discharge the obligations on its part to be kept and
performed under the terms of this Lease, Tenant's tenancy shall not be
disturbed, nor shall this Lease be affected by any default under such Mortgage,
and in the event of a foreclosure or other enforcement of any such Mortgage, or
sale in lieu thereof, the purchaser at such foreclosure sale shall be bound to
Tenant for the term of this Lease and any extensions thereof, the rights of


                                       15

<PAGE>


Tenant hereunder shall expressly survive, and this Lease shall in all respects
continue in full force and effect so long as Tenant fully performs all of its
obligations hereunder. Tenant shall not be named as a Party defendant in any
such foreclosure suit, except as may be required by law. Landlord covenants to
use reasonable efforts to obtain a non-disturbance agreement, as described
above, from each mortgagee of Landlord.

         Tenant agrees that, simultaneously with the giving of notice to
Landlord, it will give notice to any holder of a mortgage encumbering the Leased
Premises, provided that Tenant has been notified in writing of the frame and
address of such mortgage holder, of any defaults of the Landlord or other
circumstances which would entitle Tenant to terminate this Lease specifying the
nature of the default by Landlord, and thereupon the holder of the Mortgage
shall have the right, but not the obligation, to cure any such default by
Landlord, and Tenant will not terminate this of Lease by reason of such default
unless and until it has afforded the mortgage holder the time to cure such
default afforded to Landlord hereunder. No such Lender shall, upon assuming
title to the Leased Premises, be liable for any act or omission of any prior
landlord (including Landlord), be subject to any offsets or defenses which
Tenant may have against any prior landlord, be bound by any rent or additional
rent paid for more than the then current period to any prior landlord, or be
bound by any agreement or modification of this Lease made without such Lender's
consent after Tenant has been given written notice of such Lender's assumption
of title to the Leased Premises. Nothing herein shall be conspired to be in
conflict with the provisions of Paragraph 7 hereof.

19. Assignment, Subleasing and Abandonment.

the Leased Premises without the prior written consent of Landlord, which consent
shall not be unreasonably withheld.

         b. The consent by Landlord to any assignment or subletting, shall not
constitute a waiver of the necessity for such consent to any subsequent
attempted assignment or subletting, nor shall it relieve Tenant from its
covenants and obligations under the Lease. Receipt by Landlord of rental due
hereunder from any party other than Tenant shall not be deemed to be a consent
to any such assignment or subletting, nor relieve Tenant of its obligation to
pay rental or other charges for the full term of this Lease.

agreement and hypothecation to which there has been consent shall be by

or mortgagor, and the transferee, assignee, sublessee, concessionaire, or
mortgagee shall agree in writing for the benefit of the Landlord to assume, be
bound by, and perform the terms, covenants and conditions of this Lease to be
done, kept and performed by Tenant and to retain all accounting records which
Tenant is obligated to retain hereunder. One executed copy of such written
instrument shall be delivered to Landlord. Each transfer, assignment,
subletting, license or concession agreement between Tenant and the transferee,
assignee, sublessee, licensee or concessionaire, shall specifically obligate
such third party to observe and perform all of the obligations of this Lease and
indicate that Landlord has the right to audit such other parties in accordance
with the terms of this Lease.

         d. Unless expressly consented to in writing which consent shall not be
unreasonably withheld, no assignment or subletting shall operate to relieve the
Tenant from its obligation for the performance of all terms and conditions of
this Lease, including the obligation to pay rent and all of the other terms,
covenants and conditions of this Lease shall continue in full force and effect
and unamended.

(ii) comply with any Legal Requirement, (iii) discharge or remove any lien
referred to in Paragraphs 9 or 14, or (iv) take any action with respect to any
encroachment, violation, hindrance, obstruction or impairment so long as Tenant
shall contest, in good faith and at its expense, the existence, the amount or
the validity thereof, the amount of the damages caused thereby, or the intent of
its or Landlord's liability therefor, by appropriate proceedings which shall
operate during the pendency thereof to prevent (i) the collection of, or other
realization upon, the Taxes or lien so contested, (ii) the sale, forfeiture or
loss of any of the Leased Premises, any Base Rent to satisfy the same or to pay
any damages caused by the violation of any such Legal Requirement or by any such
encroachment, violation, hindrance, obstruction or impairment, (iii) any
interference with the use or occupancy of any of the Leased Premises, (iv) any
interference with the payment of any Base Rent, and (v) the cancellation of any
fire or other insurance policy. Tenant shall provide Landlord security
satisfactory in the reasonable opinion of Landlord assuring the payment,
compliance, discharge, removal or other action, including all costs, attorneys'
fees, interest and penalties, in the event that the contest is unsuccessful.
While any such proceedings are pending and the required security is held by
Landlord, Landlord shall not have the right to pay, remove or cause to be
discharged the Taxes or lien thereby being contested. Tenant further agrees that
each such contest shall be promptly and diligently prosecuted to a final
conclusion, except that Tenant shall, so long as the conditions of the first
sentence of this Paragraph are at all times complied with, have the right to
attempt to settle or compromise such contest through negotiations. Tenant shall
pay and save Landlord harmless against any and all losses, judgments, decrees
and costs (including all attorneys' fees and expenses) in connection with any
such contest and shall, promptly after the final determination of such contest,
fully pay and discharge the amounts which shall be levied, assessed, charged or
imposed or be determined to be payable therein or in connection therewith,
together with all penalties, fines, interest, costs and expenses thereof or in
connection therewith, and perform all acts the performance of which shall be
ordered or decreed as a result thereof. No such contest shall subject Landlord
to the rink of any civil or criminal liability.

         therein specified, the Term and the estate hereby granted and all
         rights of Tenant hereunder shall expire and terminate as if such date
         were the date hereinbefore fixed for the expiration of the Term, but

         amounts due from Tenant hereunder as hereinafter provided.

                  ii. Landlord may, whether or not the Term of this Lease stall
         have been terminated pursuant to clause (1) above, (i) give Tenant
         notice to surrender any of the Leased Premises to Landlord immediately

         entry, repossession or removal, except as a result of Landlord's
         negligence or willful misconduct. No such entry or repossession shall
         be construed as an election by Landlord to terminate this Lease unless
         Landlord gives a written notice of such intention to Tenant pursuant to
         clause (1) above.

         the event of termination of Tenant's right of possession pursuant to

         pursuant to clause (1) above, Landlord shall have the right to relet
         the Leased Premises or any part thereof to such tenant or tenants for
         such term or terms (which may be greater or less than the period which
         would otherwise have constituted the balance of the Term) for such
         rent, on such conditions and for such uses as Landlord, in its absolute
         discretion, may determine; and Landlord may collect and receive any
         rents payable by reason of such reletting. Landlord shall use
         reasonable efforts to mitigate damages.

                  iv. Landlord may exercise any other right or remedy now or

operation of law, repossession of the Leased Premises pursuant to Paragraph

Paragraph 21(6)(3), shall relieve Tenant of any of its liabilities and
obligations hereunder, including the liability for Base Rent, all of which shall
survive such expiration, termination, repossession or reletting.

permitted by applicable law, to injunctive


                                       19

prospective purchaser of or Lender on the Leased Premises.

any event be excused, from prompt payment of any Base Rent or additional rent or
other charges due Landlord from Tenant or to excuse either party from their
respective obligations to carry insurance as required under this Lease.

that Landlord shall not be personally liable for any of the covenants,
