                         ARTICLE 2 - TERM AND POSSESSION
                         -------------------------------

SECTION 2.01 - TERM. The term of this Lease (the "Term") shall be the period of
time specified in Item F of the Basic Lease Provisions and shall commence on the
Commencement Date as set forth in Section 2.02 below. The "Commencement Date,"
and the "Expiration Date" shall be confirmed by Tenant as provided in Section
2.03.

SECTION 2.02 - CONSTRUCTION OF IMPROVEMENTS AND POSSESSION. The scope of the
work to be performed by Landlord is set forth in the preliminary plans and
specifications and written descriptions thereto drafted by Lehman Contractors as
of September, 1998, all of which are listed on the attached Preliminary Exhibit
C. Landlord will prepare final plans and specifications and actual working
drawings and upon completion, a listing thereof shall be substituted and
attached hereto as Final Exhibit C ("Plans and Specifications"). Landlord shall
construct the Building, parking area and grounds in a good and workmanlike
manner.

Landlord shall apply for and obtain all permits, licenses and certificates
necessary for the construction of the Building and for the occupancy thereof by
Tenant. For purposes of this Lease, Landlord's procurement of a temporary
permit, license or certificate shall be sufficient for purposes of Tenant's
occupancy of the Leased Premises. However, Landlord shall be obligated to
diligently obtain a permanent certificate of occupancy as well as other
permanent or written permits, licenses and certificates regardless of whether a
temporary certificate shall have first been issued. Landlord and Tenant shall
work together to attempt to procure tax abatements for the subject parcel,
however, this Lease shall be effective regardless of receipt of tax abatements
for the parcel.

The Leased Premises shall be deemed to be constructively completed at such time
as (i) Landlord shall certify in writing to Tenant that said Leased Premises
have been completed in accordance with the Plans and Specifications described
above, (ii) Landlord shall have obtained all necessary governmental approvals
and inspections, that all systems are fully operational, and that sufficient
utilities are available to service the Leased Premises and are connected to
mains and all meters are set and activated, and (iii) the project architect,
Meacham & Abel, using commercially reasonable judgment standard in the industry
shall certify in writing to Tenant pursuant to and in accordance with form
AIA-G704 as to those same matters in (i) and (ii) immediately preceding. At such
time as the last of the foregoing requirements shall have been satisfied,
Landlord shall deliver possession of the Leased Premises to Tenant. For purposes
of this paragraph, evidence of constructive completion pursuant to all Plans and
Specifications shall include the installation of access roads and curb cuts,
paved parking areas, landscaping, exterior lighting, exterior irrigation systems
and removal of all construction trailers and dumpsters and/or Tenant's occupancy
of all or a portion of the Leased Premises for business purposes contemplated in
Item I of the Basic Lease Provisions. The date upon which Landlord shall deliver
possession of the Leased Premises to Tenant constructively completed is herein
called the "Completion Date." The anticipated Completion Date shall occur on or
before July 1, 1999.

Within twenty-one (21) days prior to the anticipated Completion Date, Tenant and
Landlord shall, by a joint inspection of the Leased Premises, mutually agree to
and identify the punchlist items to be completed by Landlord on or before the
Completion Date. Within five (5) days prior to the anticipated Completion Date,
Tenant and Landlord shall again, by joint inspection of the Leased Premises,
mutually agree to and identify any remaining punchlist items to be completed by
the Landlord on or before the Completion Date. Tenant hereby designates Terry L.
Sanborn or Charles T. Sherman as its duly authorized representative to (i)
request and sign change orders, (ii) agree to and identify the foregoing
punchlist items, and (iii) accept delivery of possession of the Leased Premises
on behalf of Tenant. The Commencement Date shall occur on the 1st day after the
Completion Date.

The parties acknowledge and agree that it will be necessary for the parties to
act timely in order to allow Landlord to meet the anticipated Commencement Date.
To this end, it is agreed that Tenant shall respond timely to any and all
requests for decisions by Tenant as to any and all issues concerning the Plans
and Specifications. In any event, so long as Tenant responds within ten (10)
business days to any request from Landlord, such response shall be considered
timely. Any delay by Tenant in making decisions affecting the Plans and
Specifications or amendments thereto may cause delay in the Completion Date
which delay shall be a Tenant Delay as set forth below. In the event Tenant
fails to respond within a timely fashion, then such failure shall be deemed to
be a consent of Landlord's proposed action.



                                       48
<PAGE>   8


The Completion Date shall be subject to change as a result of delays in the
construction of the Leased Premises caused by force majeure events as defined in
Section 14.07 herein ("Excusable Delays"). Landlord shall provide to Tenant
reasonable notice of the occurrence of an Excusable Delay. In the case of a
continuing delay only one (1) notice is necessary. In the event delay is solely
or substantially caused by the Tenant or Tenant oriented change orders ("Tenant
Delay"), the Completion Date shall not be delayed and Tenant's obligations
hereunder shall commence as if the delay has not occurred. No delay caused by
Tenant shall be deemed to have occurred until Tenant has received written notice
from Landlord specifying the action or inaction by Tenant which constitutes THE
delay caused by Tenant and Landlord shall receive the benefit of the actual
number of days of the delay only upon Tenant's receipt of the foregoing Notice.

Within thirty (30) days prior to the anticipated Completion Date, Tenant may
enter the Leased Premises and perform therein fixturing in preparation for its
occupation thereof, prior to the date on which Tenant is otherwise entitled to
possession of the Leased Premises; provided, however, Tenant shall arrange its
schedule so as not to unreasonably interfere with or delay other work of
Landlord or any permitting or inspection process being carried on at the same
time; and provided further that neither Landlord nor any of Landlord's
affiliates shall have any responsibility or liability whatsoever for any injury
(including death) to persons or loss or damage to any of Tenant's leasehold
improvements, fixtures, equipment or any other materials installed or left in
the Leased Premises prior to the Commencement Date.

Landlord hereby warrants for a period of one (1) year from the Completion Date,
the Leased Premises against defects in materials and workmanship, routine
maintenance (except as to Landlord's obligations herein) and ordinary wear and
tear excepted. Upon the Completion Date, Landlord shall deliver to Tenant copies
of all warranties and guarantees relating to the Leased Premises and any and all
systems contained therein including those warranties greater than one (1) year.
To the extent permitted by such warranties and guarantees, Landlord shall assign
the same to Tenant. To the extent not so permitted, Landlord shall afford to
Tenant the benefit of and right to enforce the same in Landlord's name. Tenant
shall not take any action which shall invalidate any of the foregoing warranties
or guarantees.

SECTION 2.03 - TENANT'S ACCEPTANCE OF THE LEASED PREMISES. Upon delivery of
possession of the Leased Premises to Tenant as hereinbefore provided, Tenant
shall execute a letter of understanding acknowledging (i) the Commencement Date
and Expiration Date of this Lease, (ii) that Tenant has accepted the Leased
Premises for occupancy and that the condition of the Leased Premises, including
the tenant finish improvements constructed thereon, and the Building was at the
time satisfactory and in conformity with the provisions of this Lease in all
respects, except for any defects as to which Tenant shall give written notice to
Landlord within thirty (30) days after such delivery and except for latent
defects. Landlord shall promptly thereafter correct all such defects and (iii)
provide Tenant with the actual Total Project Cost. Such letter of understanding
shall become a part of this Lease. If Tenant takes possession of and occupies
the Leased Premises for the



                                       49
<PAGE>   9


business purposes set forth in Item J of the Basic Lease Provisions, Tenant
shall be deemed to have accepted the Leased Premises in the manner described in
this Section 2.03, even though the letter of understanding provided for herein
may not have been executed by Tenant, which possession shall not waive Tenant's
rights with regard to existing or latent defects or Landlord's failure to
complete the Leased Premises in accordance with the Plans and Specifications as
set forth in a written notice from Tenant.

SECTION 2.04 - SURRENDER OF THE LEASED PREMISES. Upon the expiration or earlier
termination of this Lease, or upon the exercise by Landlord of its right to
re-enter the Leased Premises without terminating this. Lease, Tenant shall
immediately surrender the Leased Premises to Landlord, together with all
alterations, improvements and other property as provided else where herein, in
broom-clean condition and in good order, condition and repair, except for
ordinary wear and tear and damage from fire or the elements, unless caused by
Tenant's actions or failure to act, and damage which Tenant is not obligated
under the terms of this Lease to repair, failing which Landlord may restore the
Leased Premises to such condition at Tenant's reasonable expense.

SECTION 2.05 - HOLDING OVER. If Tenant holds over after the expiration or
earlier termination of this Lease with or without the consent of Landlord,
Tenant shall become a tenant from month to month at rent equal to one hundred
fifteen percent (115%) of the Minimum Annual Net Rent and Annual Rental
Adjustment in effect during the last full month of the Term of the Lease, and
otherwise upon the terms, covenants and conditions herein specified, so far as
applicable and upon such other and different terms and conditions as Landlord
may from time to time so notify Tenant. Acceptance by Landlord of rent after
such expiration or earlier termination shall not result in a renewal of this
Lease. Notwithstanding the foregoing provision, no holding over by Tenant shall
operate to extend this Lease, and Tenant shall vacate and surrender the Leased
Premises to Landlord upon Tenant's being given written notice from Landlord to
vacate. The foregoing provisions of this Section 2.06 are in addition to and do
not affect Landlord's right of re-entry or any other rights of Landlord
hereunder or as otherwise provided by law.

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

SECTION 3.01 - MINIMUM NET RENT. Tenant shall pay to Landlord as Minimum Annual
Net Rent for the Leased Premises the sum specified in Item D of the Basic Lease
Provisions, payable in equal consecutive Monthly Rental Installments as
specified in Item E of the Basic Lease Provisions, in advance, without demand,
deduction, counterclaim or offset except as specifically permitted by this Lease
and without relief from valuation and appraisement laws, on or before the first
day of each and every calendar month during the Term of this Lease; provided,
however, that if the Commencement Date shall be a day other than the first day
of a calendar month or the Expiration Date shall be a day other than the last
day of a calendar month, the Monthly Rental Installment for such first or last
fractional month shall be prorated on the basis of the number of days during the
month this Lease was in effect in relation to the total number of days in such
month.

<PAGE>   10


SECTION 3.02 - RENTAL RATE REDUCTION FORMULA. In the event Landlord is able to
reduce Total Project Costs which results in the final Total Project Costs being
less than the approved budget (Exhibit "B"), then the Minimum Annual Net Rent
shall be reduced proportionately with such cost savings. The Minimum Annual Net
Rent reduction shall be equal to the savings amount times 11.6%. Such sum shall
be known as the "Minimum Annual Net Rental Reduction Amount" which shall apply
to years 1 through 5 of the lease and that sum shall be divided by 12 to
determine the monthly reduction, i.e., savings amount times 11.6% divided by
40,750 SF = Rental Reduction Amount. Example, $100,000 savings amount times
11.6% = $11,600 divided by 40,750 SF = $.28 PSF per annum, Annual Net Per
Rentable Sq. Ft. Rate Reduction.

SECTION 3.03 - NET LEASE. This Lease is a net Lease, it being the intention of
the parties hereto that Tenant shall pay as additional rent as of the
Commencement Date, all Operating Expenses incurred in owning and operating the
Leased Premises. All taxes and assessments or governmental impositions in lieu
thereof, be they special or otherwise of every kind and nature; and in addition,
Tenant also agrees to pay as additional rent, water, sewer, and other rents,
rates and charges, excises, levies, license fees, permit fees, and other
authorization fees, public dues, and all other charges (in each case whether
general or special, ordinary or extraordinary, or foreseen or unforeseen), of
every character including all penalties or interest thereon, which at any time
during or in respect to the term of this Lease may be assessed, levied,
confirmed, or imposed, on or in respect or be a lien upon or measured by the
value or amount of (a) the Demised Premises or any part thereof or any rent
therefrom or any estate, right, or interest therein, or (b) any occupancy, use,
or possession of the Demised Premises or any part thereof, other than any
franchise, capital stock, or similar tax of Landlord, or any income or excess
profit tax of Landlord or portion thereof determined on the basis of its general
income or revenues (the same being hereinafter referred to as "Impositions").
Tenant's failure to pay the same as herein provided, and all other damages,
costs, and expenses which Landlord may suffer or incur, or which may become due,
by reason of any default of Tenant or failure on Tenant's part to comply with
the covenants, agreements, terms, and conditions of this Lease on Tenant's part
to be performed, and each or any of them, shall be deemed to be additional rent
and in the event of non-payment, Landlord shall have all the rights and remedies
herein provided in the case of nonpayment of rent.

SECTION 3.04 - COSTS OF CONTESTING REAL ESTATE TAXES. In the event Landlord or
Tenant elects to contest the amount or validity of real estate taxes, Tenant
shall only be responsible to pay its proportionate share of such expenses to the
extent the intended benefits of the same would be realized during the Lease Term
(including any renewal terms, but only at such time when actually exercised by
Tenant), and in this respect if the benefit to be received by the Landlord in
contesting the amount or validity of such taxes would continue past the duration
of the Lease Term (including any renewal terms, but only at such time when
actually exercised by Tenant), then Tenant shall only be required to pay towards
its proportionate share of such expenses the amount of the same determined by
multiplying the same by a ratio, the numerator of which is the number of



                                       51
<PAGE>   11


days from the date the Landlord contests the amount or validity of such taxes to
the end of the Lease Term (including any renewal terms, but only at such time
when actually exercised by Tenant), and the denominator of which is the total
number of days for which any given benefit of such contest is actually realized,
and to the extent the duration of such time period is uncertain, Landlord and
Tenant shall estimate the same based upon the then existing practices of the
applicable school district in further contesting tax valuations in the local
community, the remaining time prior to the next county wide re-evaluation of tax
valuations, and such other matters as may be reasonably expected to effect such
time period. Landlord and Tenant acknowledge that because the expenses of
contesting such taxes may occur prior to the time when Tenant must exercise any
of its applicable renewal options hereunder that any calculation (and payment)
made under the above referenced formula may accordingly need to be adjusted at
that time when Tenant does, in fact, exercise any such renewal option. Nothing
set forth in the aforementioned is intended to mean that the Tenant's
proportionate share of the costs of contesting the amount or validity of such
taxes would only be charged to the Tenant if the Landlord is successful in
actually reducing the same, and in fact, so long as Landlord acts with
reasonable prudence and in good faith in contesting the same, the success or
failure of the Landlord in actually reducing the taxes in not a factor in
charging the Tenant its proportionate share of the same.

Tenant shall be authorized to contest the taxes separate and apart from Landlord
with Tenant to act as Attorney-in-Fact for Landlord in prosecuting such appeal.
Landlord agrees to execute any and all documents which may be necessary to
enable Tenant to contest such tax valuation. Landlord shall not contest taxes
without Tenant's prior written consent.

SECTION 3.05 - LATE CHARGES. Tenant acknowledges that late payments by Tenant to
Landlord of Minimum Annual Rent and all other amounts provided to be paid
hereunder shall cause Landlord to incur costs not contemplated by this Lease,
the exact amount of which are extremely difficult and impractical to determine.
Such costs include, without limitation, processing and accounting charges and
late charges that may be imposed on Landlord by the terms of any encumbrances
and notes secured by any encumbrances covering the Leased Premises, or late
charges and penalties by virtue of late payments of taxes due on the Lease
Premises. Therefore, if any installment of Minimum Annual Rent or any other
amount due from Tenant is not received by Landlord within ten (10) days of the
date due, Tenant shall pay to Landlord an additional sum of five percent (5%) of
the amount due as a late charge. The parties agree that this late charge
represents a fair and reasonable estimate of the costs that Landlord will incur
by reason of the late payment by Tenant. Acceptance of any late charge shall not
constitute a waiver of Tenant's default with respect to the overdue amount, nor
prevent Landlord from exercising any of the other rights and remedies available
to Landlord. In addition, in the event Tenant fails to pay any other charge
(other than minimum Annual Rent) within ten (10) days after the same is due and
payable any installment of Minimum Annual Rent or any other sum or charge
required to be paid by Tenant to Landlord under Us Lease, such unpaid amount



                                       52
<PAGE>   12


shall bear interest from the due date thereof to the date of payment at the
Prime Rate plus three percent (3%) per annum until paid.

                          ARTICLE 4 - OCCUPANCY AND USE

SECTION 4.01 - OCCUPANCY. Tenant shall use and occupy the Leased Premises for
the purposes set forth in Item I of the Basic Lease Provisions and shall not use
the Leased Premises for any other purpose except with the prior written consent
of Landlord.

SECTION 4.02 - COVENANTS OF TENANT REGARDING USE. In connection with its use of
the Leased Premises, Tenant agrees to do the following:

      A.    Tenant shall use the Leased Premises and conduct its business
            thereon in a safe, careful, reputable and lawful manner.

      B.    Tenant shall not use the Leased Premises for any unlawful purpose or
            act; shall not commit or permit any waste or damage to the Leased
            Premises; shall comply with and obey all laws. regulations and
            orders of any governmental authority or agency; all reasonable
            requirements of Landlord's insurance carrier adopted or reasonably
            modified from time to time by Landlord on reasonable notice to
            Tenant which shall not unreasonably interfere with Tenant's conduct
            of its business;

      C.    Tenant shall not overload the floors of the Leased Premises beyond
            their designed weight-bearing capacity as set forth in the Plans and
            Specifications.

      D.    Tenant shall not use the Leased Premises, or allow the Leased
            Premises to be used, for any purpose or in any manner which would,
            in Landlord's commercially reasonable opinion, invalidate any policy
            of insurance now or hereafter carried on the Building or increase
            the rate of premiums payable on any such insurance policy. Should
            Tenant fail to comply with this covenant, Landlord may, at its
            option, require Tenant to stop engaging in such activity or to
            reimburse Landlord as additional rent for any increase in premiums
            charged during the Term of this Lease on the insurance carried by
            Landlord on the Building and attributable to the use being made of
            the Leased Premises by Tenant. Landlord acknowledges that Tenant's
            anticipated use does not invalidate any policy of insurance to be
            placed on the Leased Premises.

      E.    Tenant shall adhere to City of Columbus and City Gate Business Park
            signage covenants in painting, affixing, or displaying any signs on
            the Building or the Building premises. In addition, Tenant shall
            comply in all aspects to applicable building codes regarding the
            placement of such signage.

<PAGE>   13


SECTION 4.03 - ACCESS TO AND INSPECTION OF THE LEASED PREMISES. Landlord, its
employees and agents and any mortgagee of the Building shall have the right to
enter any part of the Leased Premises at reasonable times with forty-eight (48)
hours notice except in cases of emergency and with an escort provided by Tenant,
for the purposes of examining or inspecting the same, showing the same to
prospective purchasers, mortgagees or tenants (but only during the last nine (9)
months of the Term of this Lease for prospective tenants) and making such
repairs, alterations or improvements to the Leased Premises or the Building as
Landlord may deem necessary or desirable; provided, however, except in the case
of emergencies, Tenant shall be given written notice and the opportunity to
repair, alter or improve. If representatives of Tenant shall not be present to
open and permit such entry into the Leased Premises at any time when such
emergency entry is necessary hereunder, Landlord and its employees and agents
may enter the Leased Premises by means of a master or pass key or otherwise.
Landlord shall incur no liability to Tenant for any emergency entry, except for
acts of gross negligence or wanton misconduct, nor shall such entry constitute
an eviction of Tenant or a termination of this Lease, or entitle Tenant to any
abatement of rent therefor; provided, however, such entry shall minimize any
disruption to Tenant's business to the extent reasonably possible.

                              ARTICLE 5 - UTILITIES

SECTION 5.01 - SERVICES TO BE PROVIDED. Landlord shall make available to Tenant
all utilities necessary for Tenant's occupancy. Such utilities shall be
separately metered and billed directly to Tenant.

At all times Tenant's use of electric current shall never exceed the initial
capacity of the feeders to the Building or the risers or wiring installation. If
Landlord determines that the electricity used by the equipment to be so
installed or connected exceeds the initial designed load capacity of the
Building's electrical system or is in any way incompatible therewith, then
Landlord shall have the right, as a condition to granting its consent, to make
such modifications to the electrical system or other parts of the Building, or
to require Tenant to make such modifications to the equipment to be installed or
connected, as Landlord considers to be reasonably necessary before such
equipment may be so installed or connected. All costs expended by Landlord to
make any such modifications shall be borne by Tenant who shall reimburse
Landlord in full for such costs upon thirty (30) days written demand.

SECTION 5.02 - INTERRUPTION OF SERVICES. Tenant understands, acknowledges and
agrees that any one or more of the utilities or other building services
identified in Section 5.01 may be interrupted by reason of accident, emergency
or other causes beyond Landlord's control, or the quality or character of
electric service may be changed or such service may no longer be suitable for
Tenant's requirements; that Landlord does not represent or warrant the
uninterrupted availability of such utilities or building services, and that any
such interruption which is beyond Landlord's reasonable control or reasonably
required for repair, maintenance or other reason, shall not be deemed an
eviction or disturbance of



                                       54
<PAGE>   14


Tenant's right to possession, occupancy and use of the Leased Premises or any
part thereof, or render Landlord liable to Tenant for damages by abatement of
rent or otherwise, or relieve Tenant from the obligation to perform its
covenants under this Lease.

                        ARTICLE 6 - REPAIRS, MAINTENANCE,
                     ALTERATIONS, IMPROVEMENTS, AND FIXTURES

SECTION 6.01 - REPAIR AND MAINTENANCE OF BUILDING. Subject to the warranty(s)
set forth in Section 2.02, Tenant shall make all necessary repairs to the
building including but not limited to heating, ventilating, and air
conditioning, plumbing and electrical services and the exterior walls, roof,
parking lot, exterior doors, windows, and shall keep the Building in a safe
clean condition. Payment for such repairs and maintenance shall be paid by
Tenant. Except as specifically provided in this Lease, there shall be no
abatement of rent and no liability of Landlord by reason of any injury to or
interference with Tenant's business arising from the making of any repairs,
alterations or improvements in or to any portion of the Building or the Leased
Premises or in or to any fixtures, appurtenances and equipment therein or
thereon.

SECTION 6.02 - REPAIR MAINTENANCE OF LEASED PREMISES. Tenant shall keep and
maintain the Leased Premises in good order, condition, and repair. Tenant shall

Premises, including lawn care, snow removal, and parking lot care.

SECTION 6.03 - ALTERATIONS OR IMPROVEMENTS. Tenant may make, or may permit to be
made, alterations or improvements to the Leased Premises, but only if Tenant
obtains the prior written consent of Landlord thereto, such consent shall not be
unreasonably withheld, delayed or conditioned for non-mechanical, non-structural
work, subject to the provisions below; provided however, Tenant may make up to
$25,000.00 for non-mechanical and non-structural alterations or improvement
without Landlord's consent. If Landlord allows Tenant to make any such
alterations or improvements, Tenant shall secure all necessary permits and shall
make the alterations and improvements in accordance with all applicable laws and
building codes, in a good and workmanlike manner and quality substantially equal
to or better than the original construction of the building. All alterations,
additions or improvements shall be installed at Tenant's sole expense in
compliance with all applicable laws and by a licensed contractor approved in
writing by Landlord. Any alterations, improvements or utility installations in,
on or about the Leased Premises that Tenant shall desire to make shall be
presented to Landlord in written form with proposed detailed plans. If Landlord
shall give its consent, such consent shall be conditioned upon (i) Tenant's
acquiring a permit to do so from appropriate governmental agencies, (ii) the
furnishing of a copy thereof to Landlord prior to the commencement of the work,
and (iii) the compliance by Tenant of all conditions of said permit in a prompt
and expeditious manner.



                                       55
<PAGE>   15


Tenant shall promptly pay all costs attributable to such alterations and
improvements. Tenant shall promptly repair any damage to the Leased Premises or
the Building caused by any such alterations or improvements. Any alterations or
improvements to the Leased Premises paid for by Landlord, except movable office
furniture and equipment and trade fixtures, shall become a part of the realty
and the property of Landlord, and shall not be removed by Tenant. Tenant has the
option to remove alterations or improvements to the Leased Premises paid for by
Tenant.

SECTION 6.04 - TRADE FIXTURES. Any trade fixtures installed on the Leased
Premises by Tenant at its own expense, such as movable partitions, counters,
shelving, showcases, mirrors, manufacturing equipment, cranes, and the like,
shall be removed on the expiration or earlier termination of this Lease. Tenant
shall bear the cost of such removal, and repairs at its own expense any and all
damage to the Leased Premises resulting from such removal. If Tenant fails to
remove any and all fixtures from the Leased Premises on the expiration or
earlier termination of this Lease, all such trade fixtures shall become the
property of Landlord; provided, however, that Landlord may elect, by written
notice to Tenant, to require that Tenant remove all or any portion of such trade
fixtures. Promptly after receiving such notice, Tenant shall, at its expense,
promptly remove the same and restore the Leased Premises to their prior
condition, ordinary wear and tear excepted.

             ARTICLE 7 - FIRE OR OTHER CASUALTY: CASUALTY INSURANCE

SECTION 7.01 - SUBSTANTIAL DESTRUCTION OF THE BUILDING OR THE LEASED PREMISES.
If either the Building or the Leased Premises are substantially destroyed or
damaged (which as used herein, means destruction or material damage to at least
fifty percent (50%) of the Building or the Leased Premises) by fire or other
casualty, then Landlord or Tenant may, at the option of either, terminate this
Lease by giving written notice of such termination to the other within sixty
(60) days after the date of such casualty. In such event, rent shall be
apportioned to and shall cease as of the date of such casualty. If Landlord does
not exercise its option, then the Leased Premises shall be reconstructed and
restored, at Landlord's expense, to substantially the same condition as they
were prior to the casualty; provided, however, that Landlord's obligation
hereunder shall be limited to the reconstruction of such of the tenant finish
improvements as were originally required to be made by Landlord in accordance
with Final Exhibit C, and further provided that, if Tenant has made any
additional improvements pursuant to Section 6.03, Tenant shall determine if it
desires to have any or all of such improvements made, and to the extent Tenant
so elects, Landlord shall make such improvements and Tenant shall reimburse
Landlord for the cost for reconstructing the same unless such costs are covered
by insurance. In the event of such reconstruction, rent shall be abated from the
date of the casualty until substantial completion of the reconstruction repairs;
and this Lease shall continue in full force and effect for the balance of the
Term.

Notwithstanding the above, Landlord shall notify Tenant within thirty (30) days
of the substantial destruction as to whether Landlord can reconstruct the Leased
Premises within



                                       56
<PAGE>   16


seven (7) months from the date of substantial destruction. If Landlord's notice
to Tenant is that Landlord believes the Leased Premises cannot be reconstructed
within said seven (7) month period, Tenant may terminate this Lease with written
notice to Landlord within fifteen (15) days of Tenant's receipt of Landlord's
notice.

SECTION 7.02 - PARTIAL DESTRUCTION OF THE LEASED PREMISES. If the Leased
Premises are damaged by fire or other casualty, but not substantially destroyed
or damaged to the extent provided in Section 7.01, then, such damaged part of
the Leased Premises shall be reconstructed and restored, at Landlord's expense,
to substantially the same condition as it was prior to the casualty; provided,
however, that Landlord's obligation hereunder shall be limited to the
reconstruction of such of the tenant finish improvements as were originally
required to made by Landlord in accordance with Final Exhibit C, and further
provided that, if Tenant has made any additional improvements pursuant to
Section 6.03, Tenant shall determine if it desires to have any or all of such
improvements made, and to the extent Tenant so elects, Landlord shall make such
improvements and Tenant shall reimburse Landlord for the cost of reconstructing
the same unless such costs are covered by insurance. In such event, rent shall
be abated in the proportion which the approximate area of the unusable or
inaccessible part bears to the total area of the Leased Premises (however, rent
shall be 100% abated if only a portion of the Leased Premises are damaged but as
a result thereof Tenant cannot conduct business from any portion of the Leased
Premises) from the date of the casualty until substantial completion of the
reconstruction repairs; and this Lease shall continue in full force and effect
for the balance of the Term. Landlord shall use reasonable diligence in
completing such reconstruction repairs, but in the event Landlord fails to
complete the same within one hundred eighty (180) days from the date of the
casualty and Landlord shall not have diligently commenced and pursued such
construction Tenant may, at its option, terminate this Lease by giving Landlord
written notice of such termination, whereupon both parties shall be released
from all further obligations and liability hereunder.

SECTION 7.03 - TENANT'S INSURANCE. Tenant shall at all times during the Term of
this Lease carry a policy of insurance naming Tenant and Landlord as insureds as
their interest may appear which insures the full replacement value of the
Building against loss or damage by fire or other casualty (namely, the perils
against which insurance is afforded by a standard "ALL RISK" insurance policy
and extended coverage endorsement); and Rent Insurance to provide coverage for
Landlord in the event of lost rents arising from any reason whatsoever,
provided, however, that Landlord shall not be responsible for, and shall not be
obligated to insure against, any loss of or damage to any personal property of
Tenant or which Tenant may have in the Building or the Leased Premises or any
trade fixtures installed by or paid for any additional improvements which Tenant
may construct on the Leased Premises; and, notwithstanding anything contained
herein to the contrary, Landlord shall not be liable, and Tenant releases
Landlord from liability, for any loss or damage to such property, regardless of
cause, except the gross negligence or willful conduct of Landlord and its
employees, agents, customers and invitees.


                                       57
<PAGE>   17


SECTION 7.04 - WAIVER OF SUBROGATION. Notwithstanding anything in this Lease to
the contrary, Landlord and Tenant hereby release each other and each other's
employees, agents, customers and invitees from any and all liability for any
loss, damage, or injury to person or property occurring in, on, about, or to the
Leased Premises, or the Building, the Common Areas or personal property within
the Building by reason of fire or other casualty which could be insured against
under a standard fire and extended coverage insurance policy, regardless of
cause, including the negligence of Landlord or Tenant and their respective
employees, agents, customers and invitees, and agree that such insurance carried
by either of them shall contain a clause whereby the insurer waives its right of
subrogation against the other party, provided such insurance is available.
Because the provisions of this Section are intended to preclude the assignment
of any claim mentioned herein by way of subrogation or otherwise to an insurer
or any other person, each party to this Lease shall give to each insurance
company which has issued to it one or more policies of fire and extended
coverage insurance notice of the provisions of this Section. and have such
insurance policies properly endorsed, if necessary, to prevent the invalidation
of such insurance by reason of the provisions of this Section.

Provided, however, notwithstanding the foregoing, Tenant shall not be obligated
to indemnify Landlord and hold it harmless from (a) liability from which
Landlord has released Tenant as provided in Section 7.04 above, or to (b) the
extent same is covered by insurance itemized by Landlord as part of Operating
Expenses, or (c) to the extent same was not caused by Tenant or Tenant's
employees.

Tenant further agrees that in case of any claim, demand, action or cause of
action, threatened or actual, against Landlord, Tenant, upon notice from
Landlord, shall defend Landlord at Tenant's expense by counsel reasonably
satisfactory to Landlord. In the event Tenant does not provide such a defense
against any and all claims, demand, actions or causes of action, threatened or
actual, then Tenant will, in addition to the above, pay Landlord the reasonable
attorneys fees, legal expenses and costs incurred by Landlord in providing or
preparing such defense, and Tenant agrees to cooperate with Landlord in



                                       58
<PAGE>   18

such defense, including, but not limited to, the providing of affidavits and
testimony upon request of Landlord.

SECTION 8.02 - LANDLORD'S RESPONSIBILITY. Landlord does hereby indemnify,
forever save and hold Tenant and Tenant's agents, contractors, licensees,
employees, directors, officers, partners, trustees and invitees (collectively
"Tenant's Employees") harmless from and against any and all damages (but not
consequential damages), claims, losses, demands, costs, expenses (including
reasonable attorney fees and costs), obligations, liens, liabilities, actions
and causes of action, threatened or actual, which Tenant may suffer and incur
arising out of the action of Landlord.

Provided, however, notwithstanding the foregoing, Landlord shall not be
obligated to indemnify Tenant and hold it harmless from (a) liability from which
Tenant has released Landlord as provided in Section 8.02 above, or to (b) the
extent same is covered by insurance, or (c) to the extent same was not caused by
Landlord or Landlord's employees.

Landlord further agrees that in case of any claim, demand, action or cause of
action, threatened or actual, against Tenant, Landlord, upon notice from Tenant,
shall defend Tenant at Landlord's expense by counsel reasonably satisfactory to
Tenant. In the event Landlord does not provide such a defense against any and
all claims, demand, actions or causes of action, threatened or actual, then
Landlord will, in addition to the above, pay Tenant the reasonable attorneys
fees, legal expenses and costs incurred by Tenant in providing or preparing such
defense, and Landlord agrees to cooperate with Tenant in such defense,
including, but not limited to, the providing of affidavits and testimony upon
request of Tenant.

SECTION 8.03 - TENANT'S INSURANCE. Tenant shall at all times during the term of
this Lease carry, at its own expense, for the protection of Tenant and naming

<PAGE>   19


      C.    Fire and Extended Coverage, Vandalism and Malicious Mischief, and
            for the full cost of replacement of Tenant's property.

Such insurance policy or policies shall name Landlord as an additional insured
and shall provide that they may not be canceled on less than thirty (30) days
prior written notice to Landlord. Tenant shall furnish Landlord with
Certificates of Insurance evidencing such coverage. Should Tenant fail to carry
such insurance and furnish Landlord with Certificates of Insurance after a
request to do so, Landlord shall have the right to obtain such insurance and
collect the reasonable cost thereof from Tenant as additional rent.

                           ARTICLE 9 - EMINENT DOMAIN

If the whole or any significant part of the Leased Premises shall be taken for
public or quasi-public use by a governmental or other authority having the power
of eminent domain or shall be conveyed to such authority in lieu of such taking,
then Landlord and/or Tenant shall each have the option to terminate this Lease
upon sixty (60) days written notice to the other. In the event either party
exercises such option, or if such taking or conveyance would cause the remaining
part of the Leased Premises to be untenantable and inadequate for use by Tenant
for the purpose for which they were leased, then Tenant may, at its option,
terminate this Lease as of the date Tenant is required to surrender possession
of the Leased Premises by giving Landlord written notice of such termination.

If a part of the Leased Premises shall be taken or conveyed but the remaining
part is, in Tenant's reasonable judgment, tenantable and adequate for Tenant's
use, and either party exercises its option to terminate this Lease, then this
Lease shall be terminated as to the part taken or conveyed as of the date Tenant
surrenders possession; Landlord shall make such repairs, alterations and
improvements as may be necessary to render the part not taken or conveyed
tenantable; and the rent shall be reduced in proportion to the part of the
Leased Premises to taken or conveyed.

All compensation awarded for such taking or conveyance shall be the property of
Landlord without any deduction therefrom for any present or future estate of
Tenant, and Tenant hereby assigns to Landlord all its rights, title and interest
in an to any such award. However, Tenant shall have the right to recover from
such authority, but not from Landlord, such compensation as may be awarded to
Tenant on account of moving and relocation expenses or for Tenant improvement
and Tenant equipment, including without limitation, cranes and paint booths.

Notwithstanding the foregoing, (i) Landlord's option to terminate hereunder
shall be limited to the condition wherein the condemnation proceeds shall not be
made available to Landlord or the condemnation proceeds are in Landlord's
reasonable opinion insufficient for restoration purposes, and (ii) Tenant's
option to terminate shall be limited to the condition wherein due to such
condemnation or taking, Tenant cannot, in its



                                       60
<PAGE>   20


reasonable judgment, conduct its business operation in the Leased Premises
generally in the same manner as prior to the condemnation.

                               ARTICLE 10 - LIENS

If, because of any act or omission of Tenant or any person claiming by, through,
or under Tenant, any mechanic's lien or other lien shall be filed against the
Leased Premises or the Building or against other property of Landlord (whether
or not such lien is valid or enforceable as such), Tenant shall, at its own
expense, cause the same to be discharged of record within thirty-five (35) days
after the date of filing thereof (or bond over or post reasonable security to
prevent a foreclosure of such lien which Tenant contests in good faith), and
shall also indemnify Landlord and hold it harmless from any and all claims,
losses, damages, judgments, settlements, costs and expenses, including
reasonable attorneys' fees, resulting therefrom or by reason thereof. Landlord
may, but shall not be obligated to, pay the claim upon which such lien is based
so as to have such lien released of record but only after the thirty-five (35)
day period following filing of the lien claim; and, if Landlord does so, then
Tenant shall pay to Landlord, upon demand, the amount of such claim, plus all
other costs and expenses incurred in connection therewith, plus interest thereon
at the rate of Prime per annum, whichever is less.

              ARTICLE 11 - RENTAL PERSONAL PROPERTY AND OTHER TAXES

Tenant shall pay before delinquency any and all taxes, assessments, fees or
charges, including any sales, gross income, rental, business occupation or other
taxes, levied or imposed upon Tenant's business operations in the Leased
Premises and any personal property or similar taxes levied or imposed upon
Tenant's trade fixtures, leasehold improvements or personal property located
within the Leased Premises. In the event any such taxes, assessments, fees or
charges are charged to the account of, or are levied or imposed upon the
property of Landlord, Tenant shall reimburse Landlord for the same as additional
rent. Notwithstanding the foregoing, Tenant shall have the right to contest in
good faith any such item and to defer payment until after Tenant's liability
therefore is finally determined.

If any tenant finish improvements, trade fixtures, alterations or improvements
or business machines and equipment located in , or about the Leased Premises,
regardless of whether they are installed or paid for by Landlord or Tenant and
whether or not they are affixed to and become a part of the realty and the
property of Landlord, are assessed for real property tax purposes at a valuation
higher than that at which other such property in other leased space in the
Building is assessed, then Tenant shall reimburse Landlord as additional rent
for the amount of real property taxes shown on the appropriate county officials
records as having been levied upon the Building or other property of Landlord by
reason of such excess assessed valuation.

                     ARTICLE 12 - ASSIGNMENT AND SUBLETTING

SECTION 12.01 - CONSENT REQUIRED. Tenant shall not, without Landlord's prior
written consent:

            or any part of Tenant's interest in the Leased Premises or this
            Lease;

      b)    Allow any transfer thereof or any lien upon Tenant's interest in
            this Lease by operation of law;

      d)    permit the use or occupancy of the Leased Premises or any part
            thereof by anyone other Tenant; provided however, Tenant may assign
            this Lease and all obligations and duties hereunder to an entity
            controlled by controlling or under joint control with Tenant or to a
            purchaser of all or substantially all of the assets of Tenant
            without obtaining the consent of Landlord.

     If Tenant desires the consent of Landlord to an assignment or subletting of
all or a part of the Leased Premises (that portion of the Leased Premises being
assigned or sublet shall hereinafter be referred to as the "Subject Premises"),
Tenant shall submit to Landlord:

      a)    the proposed sublease or assignment,

      b)    information deemed sufficient by Landlord to permit Landlord to
            determine the acceptability of the financial responsibility and
            character of the proposed subtenant or assignee, and

      c)    the proposed sublease or assignment shall be only for the remaining
            term existing at the time the sublease or assignment is proposed and
            the proposed subtenant or assignee shall have no right to exercise
            any renewal options hereunder.

SECTION 12.02 - LANDLORD'S OPTION. Landlord within ten (10) business days after
receipt of such documents, shall, at its option:

            1)    consent to such sublease or assignment subject to the
                  provisions of Section 12.03 and 12.04 hereof which consent
                  shall not be unreasonably withheld; or

            2)    terminate this Lease for the Subject Premises and lease the
                  Subject Premises directly to subtenant or assignee in which
                  case this Lease



                                       62
<PAGE>   22

                  will remain in full force and effect as to the balance of the
                  Premises; or

            3)    refuse to consent to such sublease and assignment in which
                  case the Lease shall remain in full force and effect.

SECTION 12.03 - CONSENT GRANTED. If Landlord consents to a sublease or
assignment:

      a)    The terms and conditions of this Lease, including, without
            limitation, Tenant's liability for the Subject Premises, shall in no
            way be deemed modified, abrogated or amended.

      b)    Tenant shall pay to Landlord, Five Hundred Dollars ($500.00) for
            each proposed sublease or assignment submitted to Landlord as
            reimbursement to Landlord for expenses incurred by Landlord for the
            review of said sublease or assignment.

      c)    Any consent given hereunder by Landlord shall not be deemed a
            consent to any further subletting or assignments by Tenant,
            subtenant or assignee, unless Landlord shall have entered into a
            separate agreement with the assignee or subtenant.

      d)    If Tenant shall fail to pay the rent as provided in Article 14 of
            this Lease, and if all or any part of the Leased Premises have been
            assigned or sublet, Landlord, in addition to any other remedies
            provided by this Lease or provided by law, may, at its option,
            collect directly from the assignee or subtenant all rents becoming
            due to Tenant by reason of the assignment or sublease. Any
            collection of rents directly by Landlord from the assignee or
            subtenant shall not be construed to constitute a novation or release
            of Tenant from the further performance of its obligations under this
            Lease provided that the amounts that Tenant is obligated to pay to
            Landlord hereunder shall be reduced by the amount so collected.

SECTION 12.04 - DELIVERY. No assignment under this Article 12 shall be valid or
effective until there is delivered to Landlord a duplicate original of the
written instrument of assignment containing the name and address of the assignee
and the assumption by the assignee of this Lease and of all obligations under
this Lease to be performed by Tenant after the effective date of the assignment.
No sublease consented to by Landlord shall be valid or effective until a
duplicate original thereof shall be delivered to Landlord.

SECTION 12.05 - TRANSFER OF CONTROL. For purposes of this Article 12, Tenant
shall be authorized to assign the Lease to a third party who has acquired all or
substantially all of the assets of Tenant, provided however, that such a
transfer shall not relieve Tenant from liability hereunder.

                       ARTICLE 13 - TRANSFERS BY LANDLORD

SECTION 13.01 - SALE AND CONVEYANCE OF THE BUILDING. Landlord shall have the
right to sell, convey or transfer its Fee Simple Interest in the Building or the
control thereof at any time during the term of this Lease, subject only to the
rights of Tenant hereunder the limitations of Landlord's liability specified in
section 14.04, below and the purchaser or transferee taking title to the Fee
Simple Interest subject to this Lease.

SECTION 13.02 - SUBORDINATION. Landlord shall have the right to subordinate this
Lease to any mortgage presently existing or hereafter placed upon the Building
by so declaring in such mortgage; and the recording of any such mortgage shall
make it prior and superior to this Lease regardless of the date of execution or
recording of either document. Tenant shall, at Landlord's request, execute and
deliver to Landlord, , any reasonable instrument which may be deemed
commercially necessary or desirable by Landlord to confirm the subordination of
this Lease and an Estoppel Certificate (as described in Section 17.11 hereof);
if Tenant fails or refuses to do so, Tenant shall be liable to Landlord for
Landlord's actual costs incurred in procuring such subordination. Provided,
however, it shall be a condition precedent to any such subordination that
Landlord provide Tenant with a commercially reasonable non-disturbance agreement
executed by mortgagee under which no default by Landlord under any such mortgage
shall affect Tenant's rights hereunder so long as Tenant is not in default under
this Lease. Subject to receipt of the non-disturbance agreement, Tenant shall,
in the event any proceedings are brought for the foreclosure of any such
mortgage, attorn to the purchaser upon any such foreclosure and recognize such
purchaser as the landlord under this Lease.

                       ARTICLE 14 - DEFAULTS AND REMEDIES

SECTION 14.01 - DEFAULTS BY TENANT. The occurrence of any one or more of the
following events shall be an Event of Default under and breach of this Lease by
Tenant:

      A.    Tenant shall fail to pay any Monthly Rental Installment of Minimum
            Annual Rent or the Annual Rental Adjustment within ten (10) days
            after written notice of nonpayment by Landlord, or if Tenant shall
            fail to pay any other amounts due Landlord from Tenant as additional
            rent or otherwise, including any amounts owed by Tenant for Building
            Non-Standard Work, within thirty (30) days after written notice of
            non-payment by Landlord the same shall be due and payable.

      B.    Tenant shall fail to perform or observe any term, condition,
            covenant or obligation required to be performed or observed by it
            under this Lease for a period of thirty (30) days after written
            notice thereof from Landlord; provided, however, that if the term,
            condition, covenant or obligation to be performed by Tenant is of
            such nature that the same cannot reasonably be performed within such
            thirty (30) day period, such default shall be deemed to have been
            cured if Tenant commences such



                                       64
<PAGE>   24


            performance within said 30 day period and thereafter diligently
            undertakes to complete the same and does so complete the required
            action within a reasonable time.

      C.    Tenant shall abandon the Leased Premises for a period of ninety (90)
            days.

SECTION 14.02 - REMEDIES OF LANDLORD. Upon the occurrence of any incurred Event
of Default, Landlord shall have the following rights and remedies, in addition
to those allowed by law, any one or more of which may be exercised upon written
notice to or demand upon Tenant:

      A.    Landlord may re-enter the Leased Premises and cure any default of
            Tenant, in which event Tenant shall reimburse Landlord as additional
            rent for any costs and expenses which Landlord may incur to cure
            such default.

      B.    Landlord may terminate this Lease in which event: (i) neither Tenant
            nor any person claiming under or through Tenant shall thereafter be
            entitled to possession of the Leased Premises, and Tenant shall
            immediately thereafter surrender the Leased Premises to Landlord;
            and (ii) Landlord may re-enter the Leased Premises and dispossess
            Tenant or any other occupants of the Leased Premises by any means
            permitted by law and may remove their effects.

      C.    Landlord may, without terminating this Lease, re-enter the Leased
            Premises and re-let all or any part of the Leased Premises for a
            term different from that which would otherwise have constituted the
            balance of the term of this Lease and for rent and on terms and
            conditions different from those contained herein, whereupon Tenant
            shall immediately be obligated to pay to Landlord as liquidated
            damages the present value of the difference between the rent
            provided for herein (discounted at the Prime Rate) and that provided
            for in any lease covering a subsequent re-letting of the Leased
            Premises, for the period which would otherwise have constituted the
            balance of the term of this Lease, together with all of Landlord's
            reasonable costs and expenses for preparing the Leased Premises for
            re-letting, including all repairs, tenant finish improvements,
            brokers' and reasonable attorneys' fees.

      D.    Landlord may sue for injunctive relief or to recover damages for any
            loss resulting from the breach.

SECTION 14.03 - DEFAULT BY LANDLORD AND REMEDIES OF TENANT. It shall be a
default under and breach of this Lease by Landlord if it shall fail to perform
or observe any term, condition, covenant or obligation required to be performed
or observed by it under this Lease for a period of twenty (20) days after notice
thereof from Tenant; provided,



                                       65
<PAGE>   25


however, that if the term, condition covenant or obligation to be performed by
Landlord is of such nature that the same cannot reasonably be deemed to have
been cured if Landlord commences such performance within said twenty (20) day
period and thereafter diligently undertakes to complete the same, and does so
complete the required action within a reasonable time. Upon the occurrence of
any such default, Tenant may sue for injunctive relief or to recover damages for
any loss resulting from the breach, but Tenant shall not be entitled to
terminate this Lease or withhold, set off or abate any rent due hereunder. If
Tenant incurs damages as a result of Landlord's breach, Tenant shall be entitled
to recover, as part of a judgment against Landlord, interest at the Prime rate
of Star Bank, N.A. per annum of the costs incurred by Tenant as a result of
Landlord's breach.

SECTION 14.04 - LIMITATION OF LANDLORD'S LIABILITY. If Landlord shall fail to
perform or observe any term, condition, covenant or obligation required to be
performed or observed by it under this Lease and does not cure such failure as
provided in Section 14.03, and if Tenant shall, as a consequence thereof,
recover a money judgment against Landlord, Tenant agrees that Landlord shall
have no personal liability, and Tenant shall look solely to Landlord's right and
interest in and to the Building for the collection of such judgment; and Tenant
further agrees that no other assets of Landlord shall be subject to levy,
execution or other process for the satisfaction of Tenant's judgment and that
Landlord shall not be liable for any deficiency.

The references to "Landlord" in this Lease shall be limited to mean and include
only the owner of the Building or the owners of the Fee Simple Interest in the
Building. In the event of a sale or transfer of such interest (except a mortgage
or other transfer as security for a debt), the "Landlord" initially named
herein, or in the case of a subsequent transfer, the transferor, shall, after
the date of such transfer, be automatically relieved from all personal liability
for the performance or observance of any term, condition, covenant or obligation
thereafter required to be performed or observed by Landlord hereunder upon an
assumption in writing by Landlord's successor in interest; and the transferee
shall be deemed to have assumed all of such terms, conditions, covenants and
obligations, except as to pre-existing defaults or events of default. The
covenants and obligations contained in this Lease on the part of "Landlord"
shall be binding on the Landlord or any transferor only during the periods it is
a landlord hereunder.

SECTION 14.05 - NON-WAIVER OF DEFAULTS. The failure or delay by either party
hereto to exercise or enforce at any time any of the rights or remedies or other
provisions of this Lease shall not be construed to be a waiver thereof, nor
affect the validity of any part of this Lease or the right of either party
thereafter to exercise or enforce each and every such right or remedy or other
provision. No waiver of any default and breach of the Lease shall be deemed to
be a waiver of any other or further default and breach. The receipt by Landlord
of less than the full rent due shall not be construed to be other than a payment
on account of rent then due, nor shall any statement on Tenant's check or any
letter accompanying Tenant's check be deemed an accord and satisfaction, and
Landlord may accept such payment without prejudice to Landlord's right to
recover the balance of



                                       66
<PAGE>   26


the rent due or to pursue any other remedies provided in this Lease. No act or
omission by Landlord or its employees or agents during the Term of this Lease
shall be deemed an acceptance of a surrender of the Leased Premises, and no
agreement to accept such a surrender shall be valid unless in writing and signed
by Landlord.

SECTION 14.06 - ATTORNEYS' FEES. In the event that either party hereto shall
bring legal action against the other party and shall recover a judgment against
such party therein, then the prevailing party shall be entitled to reimbursement
from the other party for all expenses thus incurred, including reasonable
attorneys' fees.

SECTION 14.07 - FORCE MAJEURE. Except as specifically provided in this Lease to
the contrary, neither party shall be chargeable with, liable for, or responsible
to the other for anything or in any amount for any failure to perform or delay
caused by fire, earthquake, explosion, flood, 'hurricane, governmental bodies or
authorities, the elements, acts of God, war, invasion, insurrection, rebellion,
riots, or any other similar cause which is beyond the reasonable control of the
other party and any such failure or delay due to said causes or any of them
shall not be deemed a breach of or default in the performance of this Lease.
Notwithstanding the foregoing, force majeure events shall not relieve Tenant of
its obligations to pay rent hereunder except as otherwise specifically set forth
herein.

                ARTICLE 15 - LANDLORD'S RIGHT TO RELOCATE TENANT

                              INTENTIONALLY OMITTED

                    ARTICLE 16 - NOTICE AND PLACE OF PAYMENT

Lease or by law shall be deemed to have been given if it is written and
delivered in person or mailed by Registered or Certified mail, postage prepaid,
to the party who is to receive such notice at the address specified in Item K of
the Basic Lease Provisions. When so mailed, the notice shall be deemed to have
been given three (3) days after post-marked. The address specified in Item K of
the Basic Lease Provisions may be changed by giving written notice thereof to
the other party.

SECTION 16.02 - PLACE OF PAYMENT. All rent and other payments required to be

written notice given to Tenant.

No provision of this Lease may be amended or added to except by an agreement in

nature of such modification), (ii) the date to which rent has been paid, and
(iii) that there are not, to the giver's knowledge, any uncured defaults (or
specifying such defaults if any are claimed). Any such statement may be relied
upon by any prospective purchaser, mortgagee, sublessee or assignee, of all or
any part of the Building or the beneficiary. The giver's failure to deliver such
statement within such period shall be conclusive upon giver that this Lease is
in full force and effect and unmodified, and that there are no uncured defaults
in giver's performance hereunder.

SECTION 17.12 - HAZARDOUS WASTE. Landlord has had an environmental site
assessment made of the Leased Premises, a copy of which is attached as Exhibit
E, ("Environmental Site Assessment") which found no evidence of hazardous waste
contamination of the Leased Premises or other environmental conditions posing
potential liability to a purchaser or lessee.

Tenant shall not in any manner use, maintain or allow the use or maintenance of
the Leased Premises in violation of any law, ordinance, statute, regulation,
rule or order (collectively "Laws") of any governmental authority, including but
not limited to Laws governing zoning, health, safety (including fire safety),
occupational hazards, and pollution and environmental control. Tenant shall not
use, maintain or allow the use or maintenance of the Leased Premises or any part
thereof to treat, store, dispose of, transfer, release, convey or recover
Hazardous Wastes nor shall Tenant otherwise, in any manner, possess or allow the
possession of any Hazardous Wastes on or about the Leased Premises; provided,
however, any toxic material lawfully permitted and generally recognized as
necessary and appropriate for general office and machine tool manufacturing may
be stored and used on the Leased Premises so long as (i) such storage and use is
in the ordinary course of Tenant's business permitted under this Lease; (ii)
such storage and use is performed in compliance with all applicable Laws for the
storage and use of such materials; and (iii) Tenant delivers prior written
notice to Landlord of the identity of and information regarding such materials

relating thereto.


                                       69
<PAGE>   29


Landlord and its agents shall have the right, but not the duty, to inspect the
Leased Premises and conduct tests thereon at any time to determine whether or
the extent to which there is Hazardous Wastes on the Leased Premises. Landlord
shall have the right to immediately enter upon the Leased Premises to remedy any
contamination found thereon. In exercising its rights herein, Landlord shall use
reasonable efforts to minimize interference with Tenant's business but such
entry shall not constitute an eviction of Tenant, in whole or in part, and
Landlord shall not be liable for any interference, loss, or damage to Tenant's
property or business caused thereby. If any lender or governmental agency shall
ever require testing to ascertain whether there has been a release of Hazardous
Wastes or Hazardous Substances, then the reasonable costs thereof shall be
reimbursed by Tenant to Landlord upon demand as additional rent if such
requirement arose in whole or in part because of Tenant's use of the Leased
Premises. Tenant shall execute affidavits, representations and the like from
time to time, at Landlord's request, concerning Tenant's best knowledge and
belief regarding the presence of any Hazardous Wastes or Hazardous Substances,
on the Leased Premises or Tenant's intent to store or use toxic materials on the
Leased Premises. Tenant shall indemnify and hold harmless Landlord from any and
all claims, loss, liability, costs, expenses or damage, including attorneys'
fees and costs of remediation, incurred by Landlord in connection with any
breach by Tenant of its obligations under this Section. The covenants and
obligations of Tenant under this Section 17.12 shall survive the expiration or
earlier termination of this Lease.

Landlord hereby warrants and represents to Tenant to the best of Landlord's
knowledge as follows: (a) the Leased Premises is not in any way contaminated
with any hazardous, toxic or infectious waste or substances; (b) the Leased
Premises does not appear on any state or federal CERCLA lists as being
classified as a hazardous waste site; (c) there is no asbestos on the Leased
Premises; (d) there is no underground storage tank on the Leased Premises; (e)
neither Landlord nor any of Landlord's employees, agents, licensees or invitees
have placed or permitted the placement of any hazardous, toxic or infectious
waste or substances in, on or over the Leased Premises except for janitorial
purposes and only in commercially packaged quantities; (f) to the best of
Landlord's knowledge, no other party has placed any hazardous, toxic or
infectious waste or substances in, on or over the Leased Premises; (g) the
Leased Premises has not been used as a plant or site where hazardous, toxic or
infectious waste or substances is subjected to treatment, storage, disposal or
recovery; and (h) the Leased Premises is not subject to any federal, state or
local "Superfund" lien, proceedings, claim, liability or action, or the threat
or likelihood thereof, for the cleanup, removal or remediation of any such
hazardous substance from the Leased Premises. Landlord will indemnify, defend
and hold Tenant harmless from and against any and all claims, demands,
liabilities, damages, suits, actions, judgments, fines, penalties, loss, costs
and expense (including, but not limited to, attorneys' fees) arising or
resulting from, or suffered, sustained or incurred by Tenant as a result (direct
or indirect) of the untruth or inaccuracy of any of the foregoing matters
represented and warranted by Landlord to Tenant or the breach of any of the
foregoing


                                       70
<PAGE>   30

covenants and warranties of Landlord. The provisions of this Section 17.12 shall
survive the expiration or earlier termination of this Lease.

SECTION 17.13 - COVENANT OF QUIET ENJOYMENT. Landlord agrees that if Tenant
shall perform all of the covenants and agreements herein provided to be
performed on Tenant's part, Tenant shall, at all times during the Lease Term,
have the peaceable and quiet enjoyment of possession of the Leased Premises
without any manner of hindrance from Landlord, except as may be provided
elsewhere in this Lease under Section 2.05, Section 4.03, and Section 14.02.

SECTION 17.14 - CONSENT/DUTY TO ACT REASONABLY . Regardless of any reference to
the words "sole" or "absolute" (but except for matters which involve security
for the Building or which will have an adverse effect on the (a) structural
integrity of the Building, (b) the Building's plumbing, heating, life safety,
ventilating, air-conditioning, mechanical or electrical systems, or (c) which
could affect the exterior appearance of the Building, whereupon in each such
case Landlord's duty is to act in good faith and in compliance with the Lease),
any time the consent of Landlord or Tenant is required, such consent shall not
be unreasonably withheld, conditioned or delayed. Whenever the Lease grants
Landlord or Tenant the right to take action, exercise discretion, establish
rules and regulations or make allocations or other determinations, Landlord and
Tenant shall act reasonably and in good faith and take no action which might
result in the frustration of the reasonable expectations of a sophisticated
landlord and sophisticated tenant concerning the benefits to be enjoyed under
the Lease.

                       ARTICLE 18 - ADDITIONAL PROVISIONS

SECTION 18.01 - SIGNAGE. Subject to zoning, other municipal and county
regulations, the Park's covenants and restrictions and applicable county
authorities, Tenant may, at its own expense erect the following signage:

      (i)   Corporate Signage - located on the Building.
      (ii)  Monument Signage - located in the front entrance area of the
            Building
      (iii) Directional Signage - located throughout the Leased Premises.

All of the above tenant signage shall also be subject to Landlord's prior
written approval as to location, size and design. Tenant agrees to maintain each
sign in a good state of repair. Upon expiration of the Lease Term Tenant shall
remove the signs and repair any damage caused by such removal.

Landlord will not allow other signage on or about the Leased Premises; provided,
however, this Section 18.01 shall not prohibit Landlord from placing signage on
or about the Leased Premises which designates the owner, manager and/or leasing
agent for the Building which is discrete and does not detract from

market the Leased Premises and to otherwise place signs on or about the Leased

SECTION 18.02 - SALE OR REFINANCE PROCEEDS.

            (a)   In the event that at any time during the Initial Ten-n, or any
                  renewal term of this Lease, Landlord shall sell the Leased
                  Premises to any party (including, without limitation, Tenant),
                  then, provided Tenant is not in default under this Lease,
                  beyond applicable cure periods, within five (5) days after the
                  closing of such sale, Landlord shall provide to Tenant a copy
                  of the applicable purchase and sale agreement (the "Purchase
                  and Sale Agreement"), together with adjustment sheets,
                  disbursement statements, invoices, and such other evidence as
                  Tenant shall reasonably require to establish the Net Sales
                  Proceeds (as hereinafter defined) from such sale, all of which
                  shall be certified as correct and accurate by Landlord. From
                  the Net Sales Proceeds, if any, Landlord shall pay to Tenant,
                  within said five (5) day period twenty percent (20%) of the
                  Net Sales Proceeds. Upon the sale of the Property by Landlord,
                  and Tenant's receipt of its twenty percent (20%) share of the
                  excess proceeds, if any, Tenant shall have no further rights
                  under this Paragraph 18.02 (a). Provided, however, if at the
                  time of the sale of the Property, this Lease has been assigned
                  by Tenant, then the following shall apply:

                        (1)   If Tenant has remained liable for all tenant
                              obligations under this Lease, then Tenant shall be
                              entitled to the twenty percent (20%) share of the
                              Net Sales Proceeds.

                        (2)   If Tenant has no further liability under this
                              Lease, then Tenant and any subtenants or assignees
                              shall have no rights to share in the Net Sales
                              Proceeds.

            (b)   "Net Sales Proceeds" shall mean the gross sales price set
                  forth in the Purchase and Sale Agreement with adjustment for
                  any adjustments permitted or required by the Purchase and Sale
                  Agreement and minus only the following:

                  (i)   the original principal balance of the initial first
                        mortgage on the Property (which first mortgage shall not
                        have a principal balance that is greater than the Total
                        Project Cost); and



                                       72
<PAGE>   32


                  (ii)  if the initial first mortgage has been paid off, the
                        original principal balance of any first mortgage on the
                        Property that is given to refinance the initial first
                        mortgage; and

                  (iii) the amount necessary to pay off, in full, any
                        subordinate mortgages on the Property; and

                  (iv)  the amount equal to Landlord's Equity (as hereinafter
                        defined); and

                  (v)   all reasonable attorneys' fees, brokerage commissions,
                        conveyance taxes, and other closing costs, to the extent
                        actually paid by Landlord in connection with the sale,
                        provided that the same have been approved by Tenant,
                        which approval shall not be unreasonably withheld; and

                  (vi)  The amount, if any, that Landlord has not received from
                        Tenant as of the date of the sale of the property that
                        is less than an average annual return to Landlord, on
                        Landlord's equity of 11.6% through the date of sale
                        based upon a mortgage constant of 11.6%; and

                  (vii) any sums expended by Landlord to create expansion space
                        as provided herein.

            (c)   "Landlord's Equity" shall initially mean the amount by which
                  Total Project Cost exceeds the original principal balance of
                  Landlord's initial first mortgage on the Property (the
                  'Original Balance"), (also known as the Original Financing).
                  Thereafter, Landlord's Equity shall be reduced by:

                  (i)   one hundred percent (100%) of any Net Mortgage Proceeds
                        (as defined below), to the extent that Tenant does not
                        receive twenty percent (20%) thereof, pursuant to
                        Section 18.02 (d) below; and

                  (ii)  eighty percent (80%) of any Net Mortgage Proceeds, to
                        the extent that Tenant retains twenty percent (20%)
                        thereof, pursuant to Section 18.02 (d).

            (d)   In the event that at any time or times during the Initial
                  Term, or a "renewal term", of this Lease, Landlord shall
                  either refinance the first mortgage on the Property, refinance
                  a subsequent mortgage or mortgages, or put a subordinate
                  mortgage or mortgages on the Property, then within five (5)
                  days after the closing of such refinance


                                       73
<PAGE>   33


                  or subordinate mortgage, Landlord shall provide Tenant with a
                  copy of the applicable note, mortgage deed and other mortgage
                  documents, and disbursement sheets, invoices and such other
                  evidence as Tenant shall reasonably require to establish the
                  Net Mortgage Proceeds (as hereinafter defined) from such
                  mortgage transaction, all of which shall be certified as
                  correct and accurate by Landlord. If any such Net Mortgage
                  Proceeds are greater than the Total Project Cost, then
                  Landlord shall pay to Tenant, within said five (5) day period,
                  Twenty percent (20%) of the excess. Upon the sale of the
                  Property by Parker Industrial, L.L.C. (other than to an entity
                  that is affiliated with Parker Industrial, L.L.C.), Tenant
                  shall have no further rights under this Paragraph 18.02 (d),
                  the intent being that Tenant's rights under this Paragraph
                  18.02 (d) shall apply to any and all refinancing or
                  refinancings that occur while Parker Industrial, L.L.C. or any
                  affiliate thereof owns the Leased Premises, but not
                  thereafter.

            (e)   "Net Mortgage Proceeds" shall mean the face principal amount
                  of the mortgage in question, minus only the following:

                  (i)   the amount necessary to pay off, in full, any mortgage
                        that is being paid off and released with the proceeds of
                        the new mortgage, provided that such payoff amount shall
                        not include any unpaid interest or late charges; and

                  (ii)  any portion of the principal of any institutional new
                        mortgage that is not advanced at the closing of the
                        mortgage and is permitted to be advanced only to pay for
                        capital improvements or replacements to the Property
                        which either Landlord is required to make under this
                        Lease, or which have been approved by Tenant in writing,
                        provided that if any of such unadvanced proceeds are
                        subsequently advanced for any purpose other than capital
                        improvements or replacements to the Property as
                        aforesaid, then such proceeds shall be deemed to be Net
                        Mortgage Proceeds; in such event, Tenant's twenty
                        percent (20%) share shall be recalculated at that point
                        and Landlord shall, within five (5) days thereafter, pay
                        to Tenant any additional amounts due to Tenant.

                  (iii) all reasonable attorneys' fees, mortgage brokerage
                        commissions, mortgage taxes, and other closing costs, to
                        the extent actually paid by Landlord, provided that the
                        same have been approved by Tenant, which approval shall
                        not be unreasonably withheld.

bind Landlord to the terms of this Lease and that there are no encumbrances on
that title except as appears on the attached Exhibit F, Title Insurance Policy.
Landlord may mortgage or otherwise encumber the Leased Premises so long as such

SECTION 18.04 - NON-DISTURBANCE AGREEMENT. Disturbance Agreement in a form

SECTION 19.01 - RENEWAL. If Tenant is not in default or within an applicable

subject to an adjustment of the Minimum Annual Net Rent. Each option shall be
exercised by Tenant's giving written notice to Landlord of its exercise of the
option at least twelve (12) months prior to the expiration of the Lease term.

The Minimum Annual Net Rent for the first Option Period shall be 106% of the
previous year's annual rent and during the second Option Period shall be at the

SECTION 19.02 - EXPANSION SPACE. Provided that this Lease is in full force and
effect and Tenant is not in default hereunder beyond applicable grace periods
and subject to provisions of this Paragraph 19.02, subject to available
financing and Tenant's credit not deteriorating, then Tenant shall have the
right (the "Expansion Right") to require Landlord to expand the lease space for
up to 110,000 square feet of building as limited by municipal codes and park
covenants on the subject site, provided however, the term for the Expansion
Space shall be fifteen (15) years from the Date of Completion of improvements
and the rental terms shall be based upon the same formula and the terms and
conditions of this Lease; provided further however, the expiration of the lease
term for the initial space shall be extended to coincide with the fifteen year
term in the expansion space; provided further, however, that the rent payable on
the initial space after the conclusion of the initial fifteen year term shall be
based upon the rental amount that would be determined under the option period as
set forth in Section 19.01 of the Lease.


                                       75
<PAGE>   35


In the event Tenant shall have elected its Expansion Right, the renewal option
applies to both the initial space and the expansion space, provided however, the

period.

                        ARTICLE 20 - CONDITIONS PRECEDENT

This Lease is expressly conditioned upon Landlord closing on acceptable terms
upon the real property which will become the Leased Premises. This Lease is
further contingent upon Landlord and Tenant agreeing on the plans,
specifications, and budget and the Landlord and Tenant each signing an approved
set of plans, specifications and budget which plans, specifications and budget
shall be incorporated in this Lease by reference as previously provided herein.

                ARTICLE 21 - RIGHT OF TENANT TO PURCHASE BUILDING
                               PRIOR TO OCCUPANCY

Tenant shall have the option to purchase the Leased Premises at any time up
until the Commencement Date for a price equal to one hundred six percent (106%)

           ARTICLE 22 - RIGHT OF FIRST OFFER FOR PURCHASE OF BUILDING

Provided Tenant is not in default or is not within an applicable cure period,
this Lease is in full force and effect, Landlord hereby grants to Tenant the
rights herein contained with respect to the Building. If, during the term of
this Lease, Landlord desires to sell all of the Building, it shall notify Tenant
in writing of the basic Business Terms and Conditions (as hereinafter defined)
upon which it is prepared to sell the Building, and Tenant shall have thirty
(30) days after receipt to respond to such offer. The Business Terms and
Conditions, the fact that Landlord intends to sell all of the Building and such
other information Tenant or its employees or agents have obtained pursuant to
the provisions of this Section shall be kept confidential and shall not be
disclosed to any third party. If Tenant shall notify Landlord in writing within
the said 30-day period that Tenant agrees to purchase the Building upon
substantially the same Business Terms and Conditions contained in Landlord's
notice, then Landlord and Tenant shall proceed to negotiate, in good faith to
finalize the purchase price, payment terms, descriptions of property to be sold
and closing date. If Tenant fails to notify Landlord in writing within the
aforementioned 30-day notice period or fails to complete such purchase on
substantially the same Business terms and Conditions within 90 days after
expiration of such 30-day notice, for any reason other the Landlord's failure to
proceed, in good faith, toward a closing of such transaction, tenant's rights
under this Section shall be automatically terminated and of not further force or
effect. In the event Landlord does not complete a sale of the Building within
one (1) year of this termination of Tenant's right of first offer on
substantially the same terms as offered to Tenant, including a purchase price
which is



                                       76
<PAGE>   36


at least ninety-five percent (95%) of the purchase price offered to Tenant, then
Tenant's right, as set forth in this Section, shall be automatically reinstated.
In no event may Tenant assign these rights to any assignee or subtenant.
Tenant's failure to comply with the terms and conditions hereunder shall be
deemed a waiver of its rights under this Section.

                           ARTICLE 23 - TAX INCENTIVES

Landlord agrees to cooperate with Tenant in securing tax incentives and
abatements from the City of Columbus and the State of Ohio for the proposed
improvements, both real and personal, inventory and job creation on the Leased
Premises. If the City of Columbus and/or the State of Ohio do not provide Tenant
and/or Landlord with incentives that are acceptable to Tenant, in Tenant's
reasonable discretion, then within thirty (30) days after delivery of written
notice to Landlord, Tenant may terminate this Lease and, upon termination,
Tenant shall buy the Leased Premises (ground only) from Landlord for the
purchase price paid by Landlord and resell the Leased Premises to a third party.
Tenant shall also reimburse Landlord for all out of pocket costs and carrying
costs Landlord incurred in regard to the Leased Premises from the date Landlord
purchased the Leased Premises to the date Tenant buys the Leased Premises from
Landlord. All other terms of the purchase shall be consistent with commercial
practice for similar purchases of real estate in Columbus, Ohio.
