         agencies or entities, or any tenant or other person.

         "Designated Capital Investment Items" shall mean capital investment
         items which are installed to reduce or avoid increases in Operating
         Expenses, are required by governmental authority, or improve the
         operating efficiency of the Building or Land. Costs of Designated
         Capital Investment Items shall be amortized over the item's useful life
         as reasonably determined by Landlord.

         4.2.2 COMPUTATION AND PAYMENT. If Tenant's Share of the Operating
         Expenses is not included in Base Rent, then Tenant's Share of the
         Operating Expenses shall be payable on the first day of each month, in
         advance, in an amount equal to 1/12th of the initially estimated annual
         rate per square foot. Landlord may adjust the estimated monthly charge
         at the end of each calendar quarter based on Landlord's reasonably
         anticipated costs for the next quarter. Within 120 days after the end
         of each calendar year during the Term and any renewals or extensions
         thereof, Landlord shall furnish Tenant with a written statement of the
         actual Operating Expenses for that calendar year. If Tenant's Share of
         the actual Operating Expenses for any year of occupancy exceeds
         Tenant's payments for that year, Tenant shall pay Landlord the
         deficiency within ten days after receipt of written notice of the
         deficiency. If Tenant's payments for any year exceed Tenant's Share,
         the excess shall be applied to future payments or refunded at the end
         of the Term if no renewal options exist or have been exercised and if
         Tenant surrenders the Premises without default. Operating Expenses
         shall be computed annually on a calendar year basis using the accrual
         method. Tenant's Share of Operating Expenses for a partial first and/or
         last Lease Year shall be pro-rated based on the number of days of the
         applicable Lease Year falling within the calendar year.

         4.2.3 AUDIT. Provided there is no Event of Default continuing under
         this Lease and provided that Tenant strictly complies with the
         provisions of this Section 4.2.3, Tenant shall have the right, during
         normal business hours and upon reasonable advance notice to Landlord,
         to reasonably review, at its expense, supporting data for any portion
         of Landlord's annual statement of Operating Expenses; provided,
         however, that the audit shall not be conducted by a third-party
         contingency auditor. The audit shall be conducted at Landlord's offices
         located at 383 South Third Street, Columbus, Ohio 43215. Tenant must
         notify Landlord and commence its audit within sixty days after receipt
         of Landlord's statement of reconciled Operating Expenses for the
         calendar year it seeks to audit, or Tenant's right to audit shall be
         waived as to that calendar year. Tenant must have paid all outstanding
         balances required by Landlord's statement of reconciled Operating
         Expenses before requesting the review and must complete its audit
         within ninety days. Tenant agrees that all documents and data reviewed
         hereunder are confidential information of Landlord and shall not be
         disclosed to anyone other than those persons performing the review and
         principals of Tenant. Any improper disclosure is a material breach of
         the Lease. Any discrepancies which Tenant's auditor proves by clear and
         convincing evidence shall be paid by Landlord to Tenant, or by Tenant
         to Landlord, within thirty days after proof is made. This provision
         shall survive the termination of this Lease for sixty days.

     4.3 REAL PROPERTY TAXES. "Real Property Taxes" means all real property
     taxes and general and special assessments levied against the Land,
     Premises, Building and all improvements thereon. Tenant's Share of the Real
     Property Taxes is included in Base Rent.

     4.4 PAYMENT OF RENT. Tenant shall pay its Share of Operating Expenses and
     Real Property Taxes together with Base Rent, in twelve equal installments,
     in advance, on the first day of each calendar month during the Term and any
     extensions and renewals thereof. Tenant's obligation to pay Base Rent, its
     Share of Operating Expenses and Real Property Taxes, and all other charges
     due and payable hereunder (collectively, "Rent") shall be an independent
     covenant, separate from any covenants of Landlord in this Lease, and Rent
     shall be paid without set off, recoupment or demand, and without any
     counterclaim or abatement. Installments of Base Rent, Operating Expenses
     and Real Property Taxes for partial calendar month(s) shall be pro-rated
     and the pro-rated installments shall be paid in advance.

     4.5 LATE CHARGE. Delinquent installments or payments of Rent shall be
     subject to a late charge equal to 5% of the delinquent amount. The late
     charge is intended to compensate Landlord for loss and expense occasioned
     by the delinquency in payment. The provisions herein for a late charge
     shall not be construed to extend the date for payment of any installment of
     Rent, to relieve Tenant of its obligation to pay Rent when due, or as a
     waiver or cure of any default by Tenant. In addition, all Rent shall bear
     interest from the date when due until paid at the lesser of eighteen
     percent per year or the maximum rate of interest allowed by law.

     of materials before starting any work. Neither Landlord's review and
     approval of Tenant's plans and specifications, nor its observation or
     supervision of the construction or installation thereof, shall constitute
     any warranty or agreement by Landlord that they comply with applicable
     codes, ordinances, rules, regulations and/or laws ("Codes"). Tenant's
     alterations shall be approved by all appropriate governmental or
     quasi-governmental agencies, and Tenant shall obtain all applicable permits

     liability insurance policies naming Landlord as an additional insured. All
     changes and alterations shall be made at Tenant's cost in strict compliance
     with the approved plans and specifications, shall be performed in a good
     and workmanlike manner, shall not affect any Building systems or any
     structural parts of the Building, and shall not interfere with the quiet
     enjoyment of other tenants. Landlord shall have the right to inspect the
     alterations during and after construction. Tenant shall immediately correct
     any alterations which do not comply with Codes, do not conform to permits
     or to the approved plans and specifications, or adversely affect the
     Building structure or any Building systems ("Non-Conforming Alterations").



                                     Page 7
<PAGE>

     Tenant shall pay Landlord $150.00 per day for each day after the 5th day
     following Landlord's written notice that the Non-Conforming Alterations
     remain uncorrected.

     All alterations, additions, fixtures, or improvements made or installed by
     either party (except Tenant's moveable trade fixtures, personal property,
     furniture and signs), shall become a part of the Premises when made and
     shall remain upon and be surrendered with the Premises at the termination
     of this Lease for any reason; except, however, if Landlord requires that
     Tenant remove any specified alterations, additions, improvements or
     fixtures, then Tenant, at its expense shall remove the designated items and
     restore the Premises to their original condition.

9.   MECHANICS' LIENS. Tenant shall keep the Premises, the Building, and the
Land free and clear of all mechanics' and/or materialman's liens resulting from
work done by or for Tenant. If any mechanics' or materialman's liens are filed
against the Premises or the Building as a result of or purporting to be the
result of any work for or act of Tenant, Tenant shall discharge the lien within
thirty days of notice thereof by payment, or by notice and bond meeting the
requirements of the Ohio Revised Code. If Tenant does not timely discharge the
lien, Landlord may pay the lien for Tenant's account without inquiring into its
validity and treat the amount of the payment as additional Rent immediately due
from Tenant; and/or treat Tenant's failure to discharge the lien as a default.
Nothing in this Lease shall be construed as constituting the express or implied
consent or request of Landlord to any contractor, subcontractor, laborer or
materialman for the performance of any labor or the furnishing of any materials,
fuel, machinery or supplies or any specific improvements, alterations of or
repair to the Building or the Premises or any improvement thereto, nor as giving
Tenant any right, power or authority to act as Landlord's agent to contract for,
or to permit the performance or furnishing of any labor, materials, fuel,
machinery or supplies on any basis which would entitle any person to assert
and/or perfect a mechanic's lien or other claim encumbering the Building, the
Premises or Landlord's interests in the Premises. Tenant shall post and maintain
at the Premises the executed and recorded Notice of Commencement, as required by
the Ohio Revised Code, Section 1311 et seq.

10.  SIGNS. Subject to the repair, removal and governmental approval
requirements of this Section, Tenant shall have the right to maintain the
existing signs described on Exhibit C. Tenant shall not place any sign, banner
or advertising display of any kind on the exterior of the Premises, or any part
of the interior visible from the exterior, without (i) Landlord's prior written
approval and (ii) obtaining all required governmental approvals. Disapproval
based on color, size, sign material, method of mounting, support or attachment,
location or non-conformance to style or architectural integrity of the Building
is deemed reasonable. Tenant shall maintain all signs, banners, decorations,
lettering or advertising displays permitted hereunder in good condition and
repair at all times and shall remove them and restore the Building to its
previous condition at the termination of this Lease, unless otherwise directed
by Landlord.

11.  LANDLORD SERVICES. Provided that no Event of Default has occurred and is
continuing, and subject to the provisions of Section 11.7, Landlord will furnish
the utilities and services described below. All normal charges for utilities and
services, including water, heating, ventilation, air-conditioning, Building
electricity, janitorial services, security, and maintenance are included in
Operating Expenses.

     11.1 HEATING AND AIR-CONDITIONING. Landlord shall provide heating,
     ventilation, and air-conditioning ("HVAC") necessary, in Landlord's
     estimation, for comfortable occupancy of the Premises under normal business

<PAGE>

     P.M., and Saturday from 8:00 A.M. to 1:00 P.M., holidays excepted
     ("Building Hours"). Landlord shall not be liable to Tenant if HVAC services
     are interrupted or terminated because of repairs or alterations, local,
     county, state, and federal laws, regulations and curtailments, or causes
     beyond Landlord's reasonable control. Landlord will take reasonable steps
     to restore the interrupted services. Tenant shall cooperate with Landlord
     and abide by all regulations and requirements which Landlord may reasonably
     prescribe for the proper functioning and protection of the HVAC systems.

     11.2 ELECTRICITY. Landlord shall provide electricity for a reasonable level
     of illumination using 2x4 florescent light fixtures or other equipment
     providing substantially similar illumination. Landlord is not required to
     provide electricity for reproduction equipment other than machinery
     requiring standard 110 volt power, for computers or other equipment except
     standard personal computers, electric typewriters and desk adding machines,
     nor for any equipment requiring greater voltage than the lighting circuits
     standard in the Building. Any installation of nonstandard office equipment
     must have Landlord's prior approval, which will not be unreasonably
     withheld, conditioned or delayed, and shall be subject to special charges
     and regulations. Landlord shall provide all light bulbs, light globes,
     florescent tubes, ballasts and/or starters used in the Premises and
     maintain the florescent lighting equipment located in the Premises. The
     expense of lighting supplies and maintenance is included in Operating
     Expenses.

     11.3 ELEVATOR SERVICE. Landlord shall provide public passenger elevator
     service during Building Hours, and shall have one elevator subject to call
     at times when normal passenger service is not furnished.

     11.4 JANITORIAL SERVICES. Landlord shall provide janitorial service for and
     maintain the Common Areas of the Building. Landlord shall also provide the
     following janitorial services for the Premises: trash removal and ordinary
     dusting and vacuuming according to building standards. Janitorial services
     shall not include shampooing carpets or rugs, cleaning draperies or
     furniture, or other unusual services.

     11.5 WATER. Landlord shall provide water for drinking, lavatory, and toilet
     purposes in the Common Areas drawn through fixtures installed by Landlord,
     and to the Premises, if applicable.

     11.6 ADDITIONAL SERVICES. If Tenant requires more cleaning services, HVAC,
     electricity, elevator or other services than Landlord reasonably determines
     is customary for similar office space in the Columbus area or if Tenant
     requires utility or other services outside Building Hours, Landlord may,
     upon advance notice to Tenant, furnish the additional services and Tenant
     shall pay Landlord upon demand an expense charge, determined by Landlord,
     for the costs incurred in providing the additional service. Payment for
     these additional services shall be made by Tenant directly to Landlord, and
     shall not be included in Operating Expenses. If Tenant requires new or
     additional electrical facilities or other utility installations, such as
     wiring, plumbing, conduit and/or mains, Tenant shall submit detailed plans
     and specifications to Landlord for written approval. Upon receipt of
     Landlord's written approval, Tenant shall make all arrangements for and pay
     all the costs of the additional services, including construction, meters,
     and connections, in conformance with Sections 8.2 and 9. The additional
     utilities shall be metered and billed to Tenant.

     11.7 PAYMENT. Tenant shall pay for any additional services billed directly
     to Tenant within ten days after the date of Landlord's invoice. Failure to
     pay additional service charges or any Rent


                                     Page 9
<PAGE>

     when due, shall entitle Landlord, upon not less than five days' written
     notice, to stop furnishing the additional services. Discontinuing services
     pursuant to this Section 11.7 shall be cumulative with Landlord's other
     remedies, and shall not be deemed an eviction or disturbance of Tenant's
     use and occupancy of the Premises, render Landlord liable to Tenant for
     damages, relieve Tenant from the performance of Tenant's covenants and
     agreements hereunder, or prejudice Landlord's exercise of any other
     remedies available to it at law or in equity.

     11.8 LIABILITY FOR SERVICE. Landlord shall not be liable for damages, by
     abatement of rent or otherwise, for failure to furnish or delay in
     furnishing any service, or for any diminution in the quality or quantity
     thereof, when the failure or delay or diminution is occasioned, in whole or
     in part, by any strike, lockout or other labor trouble, by inability to
     secure electricity, gas, water, or other fuel at the Building after
     reasonable effort so to do, by any accident or casualty, by act or default
     of Tenant or other parties, or by any other cause beyond Landlord's
     reasonable control; and failures, delays and/or diminution shall not be
     deemed to constitute an eviction or disturbance of Tenant's use and
     possession of the Premises or relieve Tenant from the obligation to pay
     Rent or perform any of its other obligations under this Lease. Landlord
     also reserves the right temporarily to suspend, delay or discontinue
     furnishing any of the services to be provided by Landlord under this Lease,
     without abatement or diminution in Rent and without any liability to Tenant
     as a result thereof, for inspections, cleaning, repairs, replacements,
     alterations, improvements or renewals which Landlord deems necessary or
     desirable, provided that Landlord shall make reasonable efforts to minimize
     interference with Tenant's normal business operations and shall, to the
     extent reasonably possible under the circumstance, give Tenant advance
     notice of any proposed suspension of services. If any utility service
     furnished by Landlord is interrupted, delayed or terminated because of
     repairs, alterations, or any cause beyond Landlord's reasonable control,
     Landlord will take all reasonable steps to restore the interrupted utility
     or service promptly.

12.  REPAIRS. Tenant shall keep the Premises at all times in a clean, neat and
sanitary condition, as required by Section 5.2 of this Lease. Landlord will make
all repairs necessary to maintain the structure, plumbing, HVAC, and electrical
and mechanical systems serving the Building and, if installed by Landlord, the
Premises provided, as to the Premises, Tenant gives written notice of the
necessity for repair. All repairs by Landlord shall be Operating Expenses.
Notwithstanding the foregoing, if any damage to the Premises or Building is
caused by the negligence or willful act of Tenant, its concessionaires,
officers, agents, invitees, employees, licensees or contractors, Landlord shall
perform the repairs and Tenant shall pay the costs thereof plus Landlord's
supervisory fee of 15% of the cost thereof. All other maintenance, alterations
and repairs to the Premises or to any plumbing, sewer lines, electrical or other
mechanical installation placed in the Premises by Tenant, or to any of Tenant's
improvements or fixtures, are solely Tenant's responsibility; provided, however,
if the repairs affect the Building's structural components or the major
mechanical, electrical, plumbing, HVAC or other systems servicing the Building,
Landlord shall perform the repairs on behalf of Tenant and Tenant shall pay
Landlord on demand for the cost thereof plus Landlord's 15% supervisory fee. If
Tenant refuses or neglects to make and/or diligently complete any repairs which
are its obligation to make hereunder after written notice from Landlord of the
need therefor, Landlord may, but shall not be obligated to, make the repairs at
Tenant's expense. The expense of the repairs plus Landlord's 15% supervisory fee
shall be collectible on demand as additional Rent.

13.  ACCESS TO PREMISES. Landlord, its employees and agents shall have the right
to enter the Premises at all reasonable times and upon reasonable notice for the
purpose of examining or inspecting the same; showing the same to mortgagees or
to prospective purchasers, mortgages or



                                    Page 10
<PAGE>


tenants of the Building; for performing all janitorial and custodial services
and providing all utilities required by this Lease; for inspection by public
officials for health, building code, or fire and safety purposes; and/or for
making any replacements, alterations, repairs, improvements or additions to the
Premises or the Building that Landlord deems necessary or desirable. If Tenant's
representatives are not be present to open and permit entry into the Premises at
any time when entry by Landlord is necessary or permitted hereunder, Landlord
may enter by means of a master key (or forcibly in the event of an emergency)
without liability to Tenant and without the entry constituting an eviction of
Tenant or termination of this Lease. Landlord shall not be liable for any
expense, loss or damage resulting from any emergency entry.

14.  DAMAGE FROM CERTAIN CAUSES. Landlord shall not be liable for any damage
done or caused by the electrical, HVAC, plumbing, sewer, or sprinkler systems in
the Premises or the Building, nor for damage from water, snow or ice coming
through roofs, ceilings, walls, windows or otherwise, nor for the willful or
negligent acts of other tenants, or their agents, employees, representatives,
contractors, licensees or invitees. Landlord shall not be liable for damage
occasioned by the construction of the Premises and/or Building or by failure to
repair, except that Landlord shall be liable to Tenant for actual (but not
consequential) damages suffered by Tenant if Landlord fails to perform a repair
which Landlord is obligated to perform under this Lease within a reasonable time
after Landlord has actual notice of the need for the repair. Landlord shall not
at any time be liable for any damage to Tenant or to Tenant's materials,
personal property, fixtures, furniture, furnishings, equipment, ceiling, floor
and wall coverings, stock or merchandise regardless of the cause thereof unless
the damage is caused solely by the gross negligence or willful misconduct of
Landlord. In no event shall Landlord be obligated under any provision of this
Lease to repair any damage caused by any act, omission or negligence of Tenant
or its employees, agents, invitees, licensees, sublessees, or contractors.

15.   TRANSFER, ASSIGNMENT AND SUBLETTING.

      15.1 BY TENANT. Tenant shall not assign or hypothecate this Lease or any
      interest herein or sublet the Premises or any part thereof without the
      prior written consent of Landlord, which consent shall not be unreasonably
      withheld, provided that Landlord's determination that (i) the proposed
      assignee or subtenant would adversely affect the Building, other tenants
      in the Building, or the image or reputation of the Building, (ii) the
      proposed assignee's or subtenant's business would cause a material
      increase in Operating Expenses, (iii) the financial condition of the
      proposed assignee or subtenant are unacceptable to Landlord, or (iv) the
      proposed tenant's business would be disruptive or would violate an
      exclusive use provision contained in any other lease in the Building, (v)
      the proposed tenant is an existing tenant or occupant of Corporate
      Exchange Buildings IV or V or a person or entity with whom Landlord is
      negotiating or has negotiated for the lease of space in Corporate Exchange
      Buildings IV or V, shall be a reasonable basis for withholding consent. No
      assignment shall be effective, whether or not Landlord's consent is
      required, unless and until Landlord receives an executed copy of the
      assignment, in recordable form, under which the assignee assumes this
      Lease and agrees to perform and observe Tenant's covenants and conditions.

      Tenant may assign this Lease or sublet any portion of the Premises without
      Landlord's consent to any of the following: an affiliate or subsidiary of
      Tenant; a corporation resulting from the merger or consolidation of
      Tenant; or a person or entity which acquires Tenant or substantially all
      the assets of Tenant's business, provided that the acquiring entity's net
      worth is greater than Tenant's net worth on the Commencement Date. For the
      purpose of this Section 15, an "affiliate" shall


                                    Page 11
<PAGE>


     mean an entity which directly or indirectly controls, is controlled by, or
     is under common control with Tenant; "control" shall mean direct or
     indirect power to direct the management and policies of the corporation
     through ownership of voting securities, by contract or otherwise; and
     "subsidiary" shall mean an entity for which Tenant owns more than 50% of
     the outstanding stock.

     There shall not be more than one subletting during the Term, or any
     extensions or renewals, without Landlord's consent which may be withheld
     for any reason. Tenant shall pay Landlord as Rent, the entire amount of any
     and all rents, additional rents, additional charges or other consideration
     payable under or in connection with any approved sublease, which exceeds
     the Rent accruing under this Lease, including all sums paid for the sale or
     rental of Tenant's fixtures, leasehold equipment, furniture or other
     personal property. The sums due hereunder shall be Rent, due and payable at
     the time they are payable by the subtenant under the sublease.

     Regardless of Landlord's consent, no subletting or assignment shall
     release Tenant from Tenant's obligations or alter the primary liability of
     Tenant to pay Rent and to perform all other obligations to be performed by
     Tenant hereunder. Consent to one assignment or subletting shall not be
     deemed consent to any subsequent assignment or subletting. In the event of
     default by any assignee of Tenant or any successor of Tenant in the
     performance of any of the terms hereof, Landlord may proceed directly
     against Tenant without the necessity of exhausting remedies against any
     assignee or successor. Landlord may consent to subsequent assignment or
     subletting of this Lease or amendments or modifications to this Lease with
     assignees of Tenant without notifying Tenant or any successor of Tenant,
     and without obtaining its or their consent thereto and such action shall
     not relieve Tenant of liability under this Lease. Tenant shall reimburse
     Landlord for Landlord's costs, including reasonable attorney's fees,
     incurred in connection with processing any proposed assignment or sublease
     hereunder.

     15.2 BY LANDLORD. Landlord shall have the right to transfer and assign, in
     whole or in part, all of its rights and obligations hereunder and in the
     Building, and Tenant shall look to the purchaser, assignee or transferee
     of Landlord's interest in this Lease for the performance of Landlord's
     obligations hereunder, and Landlord shall from and after the conveyance,
     assignment or transfer be relieved and discharged from any and all
     liabilities and obligations under this Lease. Tenant shall attorn to any
     the purchaser, assignee or transferee.

16.   SURRENDER OF PREMISES. At the end of the Term through expiration, early
termination, or otherwise, Tenant shall surrender the Premises to Landlord,
together with all alterations, additions and improvements thereto, in as good
condition, broom clean and free of Tenant's property and any subtenancies, as it
was on the Commencement Date, ordinary wear and tear excepted. If Tenant is not
in default, Tenant shall have the right at the end of the Term to remove any
equipment, furniture, inventory or other personal property placed in the
Premises by Tenant provided that removal does not cause structural damage. If
requested by Landlord as provided in Section 8.2, Tenant shall remove any
alterations, additions, improvements or installations designated by Landlord.
Within seven calendar days after the Termination Date, Tenant at its cost shall
repair any damage to the Premises, Building and/or Land caused by the removal of
Tenant's property and shall restore the Premises, Building and/or Land to the
condition in which they were prior to the installation of the items removed,
ordinary wear and tear excepted.

17.   INDEMNIFICATION AND LIABILITY. Tenant shall indemnify, and save Landlord
harmless and, at Landlord's option, defend Landlord (with counsel acceptable to
Landlord) from and against any and all costs, expenses (including attorney's
fees), liabilities, losses, damages (actual and/or


                                    Page 12
<PAGE>

punitive), suits, penalties, actions, fines, claims, judgments or demands of any
kind asserted by or on behalf of any person or governmental authority, arising
out of or in any way connected with the Premises or Tenant's use thereof, and
Landlord shall not be liable to Tenant on account of: (i) Tenant's failure to
perform any of the agreements, covenants, terms or conditions of this Lease
required to be performed by Tenant, (ii) any failure by Tenant to comply with
any statutes, ordinances, regulations or orders of any governmental authority,
or (iii) any accident, death or personal injury, or damage to or loss or theft
of property, which shall occur in or about the Premises unless caused solely by
the gross negligence of Landlord, its employees or agents. This Section shall
not be construed to impose upon Landlord any liability as to which rights of
subrogation have been waived pursuant to Section 18.4 of this Lease.

18.   INSURANCE.

      18.1 TENANT'S COVERAGE. Tenant at its cost shall maintain commercial
      general liability and property damage insurance with a minimum single
      combined liability limit of $1,000,000 or split limits of $1,000,000 and
      $2,000,000, with Fire Legal Liability endorsements, insuring against all
      liability of Tenant, its employees, agents and guests, licensees and
      invitees, arising out of or in connection with Tenant's use or occupancy
      of the Premises and including a contractual liability endorsement covering
      the matters set forth in Section 17 and insuring Tenant's performance of
      all indemnification provisions of this Lease. Tenant shall insure the full
      replacement cost of all alterations and improvements made by Tenant in and
      to the Premises and all of Tenant's trade fixtures, furniture,
      decorations, equipment, floor and wall coverings and all other items of
      personal property of Tenant located on or within the Premises. Tenant also
      shall maintain insurance, in form and amount satisfactory to Landlord,
      against injury of any kind to person or property suffered by others as a
      result of the intentional or negligent acts of Tenant or those persons in
      the Premises or Building or on the Land in connection with Tenant. If, in
      the reasonable opinion of Landlord, Landlord's mortgagee or Landlord's
      insurance carrier, the amount of public liability or property damage
      insurance coverage provided in this Section 18.1 is not adequate, Tenant
      shall increase the insurance coverage as required by Landlord or by
      Landlord's mortgagee or insurance carrier. No damages, compensation, loss
      of income, inconvenience, loss of business, annoyance or other claims
      shall be payable by Landlord arising from any fire or other casualty or
      from any repair or restoration of any portion of the Premises, Building or
      Land.

      Before occupying or using the Premises, Tenant shall provide to Landlord
      certificates evidencing Tenant's insurance coverage and, if requested by
      Landlord, a copy of Tenant's policies of insurance, together with all
      riders, attachments, schedules, etc. Tenant's insurance shall provide that
      Landlord and Landlord's managing agent are named on the certificates,
      policies and all attachments thereto as additional insureds, shall contain
      a waiver of subrogation endorsement, shall contain a standard mortgagee
      clause, and shall bear endorsements requiring the insurer to notify
      Landlord not less than thirty days in advance of any modification or
      cancellation. Tenant's insurance policies shall permit waiver of any claim
      against Landlord and Landlord's managing agent for loss or damage within
      the scope of the insurance and Tenant, for itself and its insurers, waives
      all claims against Landlord.

      18.2 LANDLORD'S COVERAGE. Landlord shall carry policies insuring
      Landlord's improvements and the Building against those perils and losses
      that Landlord or Landlord's mortgagee reasonably deems appropriate,
      including, without limitation, fire, vandalism, malicious mischief, and
      other perils covered by extended coverage endorsements. Tenant shall have
      no rights in the


                                    Page 13
<PAGE>

     insurance policy or policies maintained by Landlord and shall not be
     entitled to be a named insured.

     18.3 LANDLORD'S INSURANCE COVERAGE ADVERSELY AFFECTED BY TENANT. If Tenant
     uses the Premises in a manner which voids, suspends or otherwise adversely
     affects Landlord's insurance coverage, Tenant shall hold Landlord harmless
     from any liability to Tenant resulting therefrom or occurring during the
     suspension, and shall reimburse or refund to Landlord as additional Rent
     any reasonable costs incurred by Landlord as a result thereof, including
     any rate increases which Landlord's insurance carrier attributes to any
     activity of Tenant.

     18.4 WAIVER OF RECOVERY AND SUBROGATION RIGHTS. Landlord and Tenant each
     hereby waives any and all rights of recovery, claims, actions or causes of
     action, against the other, its agents, servants, partners, shareholders,
     officers or employees, for any loss or damage that may occur to the
     Premises or the Building, or any improvements thereto, or any personal
     property therein, by reason of fire, the elements or any other cause which
     is insured against under the terms of the insurance policies required to be
     maintained pursuant to Sections 18.1 and 18.2 or actually maintained by the
     other party, regardless of cause or origin, including negligence of the
     other party hereto, its agents, officers, partners, shareholders, servants
     or employees, and covenants that no insurer shall hold any right of
     subrogation against the other party; provided, however, the waiver set
     forth in this Section 18.4 shall not apply to any deductibles. If an
     insurance policy required hereunder does not permit a waiver without an
     appropriate endorsement, the policy holder shall notify its insurer of the
     waiver set forth herein and secure an appropriate endorsement covering the
     waiver.

19.  FIRE OR OTHER CASUALTY. If the Premises are partially or totally damaged or
rendered wholly untenantable by fire or other casualty, or if the Building is
substantially damaged, and if Landlord decides to demolish it or not to rebuild
or restore the Building or the Premises, then within sixty days after the fire
or other casualty, Landlord shall give Tenant written notice of its decision,
and the Term shall end on the later of the third day after notice is given or
the date Tenant vacates the Premises. Tenant shall vacate the Premises and
surrender them to Landlord promptly after receipt of Landlord's notice.

If this Lease is not terminated in accordance with the preceding provisions of
this Section 19, Landlord will repair the damage, and replace, restore and
rebuild the Premises and the Building using available insurance proceeds.
Landlord has no obligation to expend more than the available insurance proceeds.
Landlord will commence repair, replacement, restoration or rebuilding as soon as
practicable after receiving notice of the damage or destruction, but under no
circumstances later than the last to occur of: (i) thirty days after settlement
and receipt of insurance proceeds, or (ii) sixty days after receipt of the
notice. Landlord shall restore the Premises substantially to their condition on
the Commencement Date. Landlord is not obligated to restore or rebuild any
tenant improvements to the Premises. Tenant shall bear the entire risk of loss,
damage or destruction of all additions, improvements, fixtures and other
property in or on the Premises or the Building.

If the Premises are partially damaged or destroyed, Base Rent and Tenant's Share
of Operating Expenses and Real Property Taxes shall abate in proportion to the
applicable part of the Premises rendered untenantable by the casualty from the
date of the damage until the Premises are substantially restored. If the
Premises are totally or substantially damaged, destroyed or rendered unfit for
Tenant's use, the entire Base Rent and Tenant's Share of Operating Expenses and
Real Property Taxes shall abate from the date of the damage until the Premises
are substantially restored.


                                    Page 14
<PAGE>



If, however, Tenant reoccupies a portion of the Premises while the restoration
work is taking place and before the entire Premises are substantially restored,
Base Rent and Tenant's Share of Operating Expenses and Real Property Taxes shall
be payable by Tenant in proportion to the part of the Premises occupied by
Tenant.

20.  CONDEMNATION. If the Premises or any material part thereof are condemned
for public use, this Lease shall terminate upon the vesting of title for public
use. If this Lease terminates due to condemnation, Rent shall be paid through
the date of termination and Tenant shall remain liable for matters described in
Sections 7, 9, 17, 23 and 27.4. If only a part of the Premises are taken and the
part not taken is sufficient for the operation of Tenant's business, Tenant
shall retain the part not taken and Base Rent and Tenant's Share of Operating
Expenses and Real Property Taxes shall be reduced proportionately. All
compensation awarded or paid upon a total or partial taking of the Premises
shall belong to Landlord without any participation by Tenant. Tenant may
prosecute any claim directly against the condemning authority for moving
expenses, or depreciation to, damage to, or cost of removal of trade fixtures,
furniture and other personal property belonging to Tenant; provided, however,
that no claim by Tenant shall diminish or otherwise adversely affect Landlord's
award or the award of any mortgagee of Landlord.

21.  SUBORDINATION, ATTORNMENT AND NON-DISTURBANCE. Tenant accepts this Lease
subject and subordinate to all mortgages (including, without limitation, the
notes or other obligations secured thereby, any assignments of leases and rents
securing such notes and any and all renewals, modifications, consolidations,
replacements or extensions of any mortgages, notes or other obligations secured
thereby) now in existence or hereinafter made by Landlord as mortgagor from time
to time, affecting the fee title or the leasehold estate to the Building or any
part thereof or Landlord's interest therein, provided that so long as Tenant
complies with all the terms, obligations, and conditions of this Lease, Tenant's
use and possession of the Premises shall remain undisturbed and this Lease shall
not terminate. Tenant also accepts this Lease subject and subordinate to all
instruments in the chain of fee title and/or the leasehold estate of Landlord to
the Building or the Land, including, without limitation, any and all renewals,
modifications, consolidations, replacements or extensions of such instruments.
This clause shall be self-operative and no further instrument of subordination
shall be required in confirmation thereof. Notwithstanding the foregoing, Tenant
shall execute, acknowledge and deliver to the holder of any mortgages or to any
of the parties to such instruments, at any time upon demand by the holder or by
any such party, any releases, certificates, further assurances or other
documents that may be required by the holder or by any such party, for the
purpose of evidencing the subordination of this Lease to the mortgages or
instruments or to any renewals, modifications, consolidations, replacements or
extensions thereof. In the event of a sale under any mortgage (or any note or
other obligation secured thereby) to which this Lease is subordinate, or a
taking of possession of the Premises by the mortgagee or other person acting for
or through the mortgagee under any mortgage to which this Lease is subordinate,
then and upon the happening of any such events, if the mortgagee or other person
acting under or through the mortgagee shall so request, Tenant shall attorn to
and recognize the mortgagee as Landlord. This attornment shall be effective and
self-operative, without the execution of any other instruments, immediately upon
the mortgagee succeeding to Landlord's interest. Tenant shall attorn to any
successor in interest to Landlord (whether succession is by purchase,
foreclosure, sale in lieu of foreclosure, power of sale, any sale-leaseback
transaction, or otherwise), if required by Landlord; provided that so long as
Tenant complies with all the terms, obligations and conditions of this Lease,
Tenant's use and possession of the Premises shall remain undisturbed and this
Lease shall not terminate. Tenant shall, upon demand, execute any agreement or
agreements confirming its attornment. Tenant shall give any mortgagee notice of
any default by Landlord under this Lease and


                                    Page 15
<PAGE>

shall afford any mortgagee the same right (but not the obligation) to cure the
default as Landlord, but not less than thirty days to cure. Landlord, Landlord's
mortgagee or any other similarly secured party, may, at their option, make this
Lease superior to any mortgage, ground lease or other security instrument by
giving Tenant ten days prior written notice. No other documentation shall be
necessary to effect this change. This Lease will, in all events, be prior to all
other mortgages or deeds of trust on the Premises at any time recorded. Tenant
will not subordinate this Lease to any other mortgage without the prior written
consent of Landlord and Landlord's mortgagee, and any attempted subordination
without such consent shall be void.

22.  ESTOPPEL CERTIFICATES. Tenant, at any time and from time to time, within
ten days after Landlord's written request, shall execute, acknowledge and
deliver to Landlord any estoppel certificates requested by Landlord certifying
that this Lease is in full force and effect and has not been assigned , amended,
extended or modified (or stating the nature of the change); the date to which
the Rent reserved hereunder has been paid; that there are no uncured defaults by
Landlord, or specifying the defaults if any are claimed; that possession has
been assumed, Tenant is in occupancy, and all improvements to be provided by
Landlord have been completed; that Tenant's address shown on the estoppel is
accurate; and other matters as Landlord reasonably may require. Any such
statement may be relied upon by any prospective assignee, purchaser or mortgagee
of all or any part of the Building or the Land. Tenant shall pay to Landlord a
fine in the amount of Five Hundred Dollars for each day after the tenth day from
Landlord's request that delivery of the estoppel certificate is delayed.

23.  DEFAULT AND REMEDIES.

     23.1 DEFINED EVENTS OF DEFAULT. The occurrence of any of the following
     shall constitute an Event of Default by Tenant: (i) Tenant fails to make
     any payment required by this Lease and the failure continues for five
     calendar days after Landlord gives written notice to Tenant; (ii) Tenant
     fails to comply with any term, provision or covenant of the Lease other
     than a required payment and does not cure the failure within ten calendar
     days after Landlord gives written notice to Tenant, or if the default
     cannot reasonably be cured within ten days, if Tenant does not commence the
     cure within ten days and thereafter diligently prosecute it to completion;
     (iii) Tenant becomes insolvent, makes a transfer in favor of creditors,
     makes an assignment for the benefit of creditors, files or has filed
     against it a petition under any section or chapter of the Bankruptcy Reform
     Act, or any law or statute of the United States or any state thereof
     relating to bankruptcy (collectively, the "Bankruptcy Code"), or a receiver
     or trustee is appointed for all or part of Tenant's assets.

     23.2 REMEDIES. If an Event of Default occurs, Landlord shall have the
     option to pursue any one or more of the remedies set forth herein. These
     remedies are not exclusive; they are cumulative and in addition to any
     other remedies contained herein or any remedies now or later allowed by law
     or in equity.

          23.2.1 Terminate this Lease by written notice to Tenant and forthwith
          repossess the Premises and be entitled to recover forthwith as damages
          a sum of money equal to the total of (i) the cost of recovering the
          Premises (including reasonable attorneys' fees and costs of suit),
          (ii) the cost of removing and storing any personal property, (iii) the
          unpaid Rent earned at the time of termination, plus interest thereon
          at the rate described in Section 4.5, (iv) the present value
          (discounted at the rate of 5% per year) of the balance of the Rent for
          the remainder of the Term, subject to subsequent reimbursement by
          Landlord to Tenant of rents actually received from other tenants of
          the Premises after using reasonable efforts to


                                    Page 16
<PAGE>

          re-let, after deducting the reasonable cost to prepare the Premises
          for occupancy and the other costs (such as leasing commissions and
          reasonable attorneys' fees) incurred by Landlord in connection
          therewith, (v) the unamortized portion of the Tenant Improvement
          Allowance, (vi) the unamortized portion of the Tenant Improvement
          Allowance paid pursuant to Sections 1.6, (vii) the full amount of all
          Rent concessions including Base Rent, Additional Operating Expenses,
          Additional Real Property Taxes and all other abated amounts, (viii)
          the unamortized portion of the real estate commission paid to CB
          Richard Ellis pursuant to Section 27.8, and (ix) all other sums of
          money and damages owed by Tenant to Landlord under this Lease or
          recoverable by Landlord from Tenant pursuant to applicable law.

          23.2.2 Terminate Tenant's right of possession (but not this Lease) and
          repossess the Premises by forcible entry and detainer suit or
          otherwise, without thereby releasing Tenant from any liability
          hereunder and without demand or notice of any kind to Tenant and
          without terminating this Lease. Landlord shall use reasonable efforts
          under the circumstances to re-let the Premises on terms and conditions
          determined by Landlord, in its discretion, which may include a term
          different than the Term of this Lease, Rent concessions, and
          alterations and repairs to the Premises; provided that Landlord makes
          reasonable efforts to mitigate its damages by reletting the Premises.
          Listing the Premises (on an exclusive or non-exclusive basis) with a
          broker in Franklin County or advertising the Premises for rent in a
          Franklin County newspaper for sixty days, and Landlord's willingness
          to enter into a new lease with a financially responsible tenant at the
          same rent as provided in this Lease shall be conclusively deemed to be
          a reasonable attempt to relet. Notwithstanding anything to the
          contrary, Landlord hereby reserves the right (i) to lease any other
          comparable space available in the Building before offering the
          Premises for lease, and (ii) to refuse to lease the Premises to any
          potential tenant which does not meet Landlord's standards and criteria
          for leasing comparable space in the Building. Provided that Landlord
          complies with the mitigation requirements contained in this Section
          23.2.2, Landlord shall not be liable for, nor shall Tenant's
          obligations hereunder be diminished because of Landlord's failure or
          refusal to re-let the Premises for the reasons specified herein, any
          re-letting of the Premises except to the extent the rent actually
          received by Landlord exceeds all amounts owed from Tenant to Landlord,
          or for any other reason except as provided by then applicable law.
          Landlord shall have the right to make any repairs, changes,
          alterations or additions in or to the Premises as may be reasonably
          necessary or desirable for re-letting them. If the Premises are re-let
          and the net proceeds of re-letting are not sufficient to satisfy the
          Rent after first deducting all unpaid Rent and all other amounts due
          hereunder at the time of re-letting plus interest at the rate
          specified in Section 4.5, the cost of recovering possession (including
          costs of suit and reasonable attorneys' fees), all costs and expenses
          of repairs, changes, alterations and additions to the Premises, the
          expense of re-letting and the cost of collecting the rent accruing
          therefrom, then Tenant shall pay to Landlord as damages a sum equal to
          the amount of the deficiency plus all other damages recoverable by
          Landlord from Tenant pursuant to applicable law. Any payments due
          Landlord pursuant to this Section 23 shall be made upon demand and
          Tenant agrees that Landlord may file suit to recover any sums falling
          due under the terms of this Section 23 from time to time. No delivery
          to or recovery by Landlord of any portion due Landlord hereunder shall
          be any defense in any action to recover any amount not theretofore
          reduced to judgment in favor of Landlord, nor shall any re-letting be
          construed as an election by Landlord to terminate this Lease unless
          Landlord gives Tenant a written termination notice. Notwithstanding
          any termination of Tenant's right of possession, Landlord may at any
          time thereafter elect to


                                    Page 17
<PAGE>

          terminate this Lease. In any proceedings to enforce this Lease under
          this Section 23, Landlord shall be presumed to have used reasonable
          efforts to re-let the Premises, and Tenant shall bear the burden of
          proof to establish that reasonable efforts were not used.

          23.2.3 Alter any and all locks and other security devices at the
          Premises, and if it does so Landlord shall not be required to provide
          a new key or other access right to Tenant unless Tenant has cured all
          Events of Default; provided, however, that during Landlord's normal
          business hours and at Landlord's convenience, and upon the written
          request of Tenant accompanied by any written waivers and releases that
          Landlord requires, Landlord will escort Tenant or its authorized
          personnel to the Premises to retrieve any personal belongings or other
          property of Tenant.

          23.2.4 Seek to obtain a restraining order and/or injunction against
          all violations, actual, attempted or threatened, of any covenant,
          condition or provision of this Lease.

     23.3 NON-WAIVER AND CUMULATION OF REMEDIES. Pursuit of any of the foregoing
     remedies by Landlord shall not preclude pursuit of other remedies provided
     to Landlord under this Lease, by law or in equity, nor shall pursuit of any
     of the other remedies constitute a forfeiture or waiver of any Rent due
     hereunder or of any damages accruing to Landlord by reason of the violation
     of any of the terms, provisions and covenants herein. The forbearance,
     failure or delay on the part of Landlord to enforce or exercise at any time
     any of the provisions, rights or remedies in this Lease shall in no way be
     construed to be a waiver thereof, nor in any way to affect the validity of
     this Lease or any part hereof, or Landlord's right to thereafter enforce
     each and every provision, right or remedy. No waiver of any breach of this
     Lease shall be held to be a waiver of any other or subsequent breach. The
     receipt by Landlord of Rent when an Event of Default has occurred shall not
     be construed as a waiver of the Event of Default. The receipt by Landlord
     of a lesser amount than the Rent due shall not be construed to be other
     than a payment on account of the Rent then due, nor shall any statement on
     Tenant's check be deemed an accord and satisfaction, and Landlord may
     accept payment without prejudice to Landlord's right to recover the balance
     of the Rent due or to pursue any other remedies provided in this Lease. No
     act or thing done by Landlord or Landlord's agents or employees during the
     Term (as extended), including acceptance of the keys to the Premises, shall
     be deemed an acceptance of a surrender of the Premises, and no agreement to
     accept a surrender shall be valid unless in writing and signed by Landlord.

     23.4 DEFAULT RENT COMPUTATION. Unpaid Rent which would have accrued and
     become payable under this Lease shall consist of the sum of: (i) the total
     Base Rent for the balance of the Term, (ii) Tenant's Additional Operating
     Expenses and Additional Real Property Taxes for the balance of the Term,
     plus (iii) the full amount of all Rent concessions including abatements of
     Base Rent, Additional Operating Expenses, Additional Real Property Taxes
     and all other abated amounts. Additional Operating Expenses and Additional
     Real Property Taxes for the calendar year of the default and each future
     calendar year in the Term (as extended) shall be equal to the Additional
     Operating Expenses and Additional Real Property Taxes for the calendar year
     before the year in which default occurs compounded at a rate equal to the
     average rate of inflation for the three calendar years preceding the
     calendar year of the default, as determined by using the United States
     Department of Labor, Bureau of Labor Statistics Consumer Price Index (All
     Urban Consumers, all items, 1982-84 equals 100) for Columbus, Ohio.

     23.5 LANDLORD'S RIGHT TO CURE DEFAULTS. All agreements and provisions to be
     performed by Tenant under any of the terms of this Lease shall be at
     Tenant's sole cost and expense and without


                                    Page 18
<PAGE>

     any abatement of Rent. If Tenant shall fail to pay any sum of money, other
     than Base Rent, or shall fail to perform any other act or obligation under
     this Lease after the failure becomes an Event of Default as provided in
     Section 23.1, or in the event of an emergency when Landlord believes
     protection of property or persons is required, then Landlord may, but shall
     not be obligated so to do, and without waiving or releasing Tenant from any
     obligations, make any payment or perform any such act on Tenant's part. All
     sums paid by Landlord and all costs incurred by Landlord in taking such
     action shall be deemed additional Rent hereunder and shall be paid to
     Landlord on demand, and Landlord shall have (in addition to all other
     rights and remedies of Landlord) the same rights and remedies in the event
     of the non-payment thereof by Tenant as in the case of default by Tenant in
     the payment of Rent.

     23.6 ATTORNEYS' FEES. If either party defaults in the performance of any of
     the terms, agreements or conditions contained in this Lease and the other
     party places the enforcement of this Lease, or any part thereof, or the
     collection of any Rent due or to become due hereunder, or recovery of the
     possession of the Premises, in the hands of an attorney who files suit, the
     defaulting party shall pay the reasonable attorneys' fees incurred by the
     non-defaulting party, provided that the non-defaulting party prevails in
     any the legal proceeding.

24.  BANKRUPTCY. If a petition is filed by or against Tenant for relief under
Title 11 of the United States Code, as amended (the "Bankruptcy Code"), and
Tenant (including for purposes of this Section, Tenant's successor in
bankruptcy, whether a trustee or Tenant as debtor in possession) assumes and
proposes to assign, or proposes to assume and assign, this Lease pursuant to the
provisions of the Bankruptcy Code to any person or entity who has made or
accepted a bona fide offer to accept an assignment of this Lease on terms
acceptable to Tenant, then notice of the proposed assignment setting forth the
name and address of the proposed assignee, all of the terms and conditions of
the offer and proposed assignment, and the adequate assurance to be furnished by
the proposed assignee of its future performance under the Lease, shall be given
to Landlord by Tenant no later than twenty days after Tenant has made or
received the offer, but in no event later than ten days prior to the date on
which Tenant applies to a court of competent jurisdiction for authority and
approval to enter into the proposed assignment. Landlord shall have the prior
right and option, to be exercised by notice to Tenant given at any time prior to
the date on which the court order authorizing the assignment becomes final and
non-appealable, to receive an assignment of this Lease upon the same terms and
conditions, and for the same consideration, if any, as the proposed assignee,
less any brokerage commissions which may otherwise be payable out of the
consideration to be paid by the proposed assignee for the assignment of this
Lease. If this Lease is assigned pursuant to the provisions of the Bankruptcy
Code, Landlord may require from the assignee a deposit or other security for the
performance of its obligations under the Lease in an amount substantially the
same as Landlord requires on initial leasing to a tenant similar to the
assignee. Any person or entity to which this Lease is assigned pursuant to the
provisions of the Bankruptcy Code shall be deemed, without further act or
documentation, to have assumed all of Tenant's obligations arising under this
Lease on and after the date of the assignment. Any assignee shall, upon demand,
execute and deliver to Landlord an instrument confirming the assumption. No
provision of this Lease shall be deemed a waiver of Landlord's rights or
remedies under the Bankruptcy Code to oppose any assumption and/or assignment of
this Lease, to require a timely performance of Tenant's obligations under this
Lease, or to regain possession of the Premises if this Lease has neither been
assumed on or rejected within sixty days after the date of the order for relief
or within any additional time set by a court of competent jurisdiction.
Notwithstanding anything in this Lease to the contrary, all amounts payable by
Tenant to or on behalf of Landlord under this Lease, whether or not expressly
denominated as Rent, shall constitute Rent for the purposes of Section 502(b)(6)
of the Bankruptcy Code.

25.  LIABILITY OF LANDLORD. Landlord and Landlord's managing agent (and in case
Landlord or its managing agent is a joint venture, partnership, tenancy in
common, association or other form of joint ownership, the members of the joint
venture, partnership, tenancy in common, association or other from of joint
ownership) shall have absolutely no personal liability with respect to any
provision of this Lease or any obligation or liability arising from or in
connection with this Lease. In the event of a breach or default by Landlord of
any of its obligations, Tenant shall look solely to the Landlord's equity in the
Building at the time of the breach or default (or if Landlord's interest is a
leasehold interest at that time, Tenant shall look solely to the leasehold
interest) for the satisfaction of any remedies of Tenant. This exculpation of
liability shall be absolute and without any exception. In the event of sale or
other transfer of Landlord's right, title and interest in the Building, Landlord
shall be released from all liability and obligations hereunder. Wherever
Landlord's liability is limited by the terms of this Lease and wherever Landlord
is indemnified and defended hereunder, the same limitations, indemnifications,
and defense requirements shall apply to Landlord's managing agent.

26.  UNFORESEEN DELAY. The provisions of this Section shall be applicable if
there shall occur, during the Term, or any renewal or extension thereof, any
strike, lockout, or labor dispute; inability to obtain labor or materials or act
of God, governmental restriction, regulation, or control, enemy or hostile
governmental action, civil commotion, insurrection, revolution, sabotage, or
fire or other casualty, or other similar condition beyond the reasonable control
of Landlord or Tenant including fuel shortages. If Landlord or Tenant shall, as
the result of such event, fail punctually to perform any obligation except for
payment of Rent or other changes due from Tenant to Landlord, then the
obligation shall be punctually performed as soon as practicable after the event
shall abate. If Landlord or Tenant shall, as a result of the event, be unable to
exercise any right or option within any time limit provided therefor in this
Lease, the time limit shall be deemed extended for a period equal to the
duration of the event.

27.  MISCELLANEOUS.

     27.1 SUCCESSORS. Except as provided in Section 15, this Lease and all
     covenants, provisions and conditions herein shall inure to the benefit of
     and be binding upon Landlord, its legal representatives, heirs, executors,
     administrators, successors and assigns, shall be binding upon Tenant, its
     heirs, administrators, legal representatives, successors and assigns, and
     shall inure to the benefit of Tenant and its Landlord-approved assigns.

     27.2 GOVERNING LAW. This Lease shall be construed, governed and enforced in
     accordance with the laws of the State of Ohio.

     27.3 SEVERABILITY. If any provisions of this Lease or the application
     thereof to any person or circumstance shall be held to be invalid, void or
     unenforceable, the remaining provisions hereof shall in no way be affected
     or impaired and the remaining provisions shall remain in full force and
     effect.

     27.4 HOLDING OVER. Tenant shall indemnify and hold harmless Landlord from
     and against any and all loss or liability resulting from Tenant's failure
     to surrender possession of the Premises in accordance with the terms and
     conditions of this Lease. No receipt of money by Landlord from Tenant after
     termination of this Lease or after the service of any notice or after the
     commencement of any suit, or after final judgment for possession of the
     Premises shall reinstate, continue or extend the Term or affect any notice,
     demand or suit, or imply consent for any action


                                    Page 20
<PAGE>

     for which Landlord's consent is required. If Tenant remains in possession
     of the Premises after termination of this Lease and without executing a new
     Lease, Tenant, at Landlord's option, shall be deemed to be occupying the
     Premises as a Tenant from month to month, at twice the Base Rent and
     subject to all other charges, conditions, provisions, and obligations of
     this Lease which are applicable to a month to month tenancy.

     27.5 CAPTIONS. Marginal captions, titles or exhibits and riders and the
     table of contents to this Lease are for convenience and reference only, and
     are in no way to be construed as defining, limiting or modifying the scope
     or intent of the various provisions of this Lease.

     27.6 NOTICES. Notices shall be given and received on the date of actual
     receipt or refusal thereof. Either party may change its Notice Address by
     written notice to the other. Landlord and Tenant shall give notices to each
     other in writing and delivered as follows:

          27.6.1 TO LANDLORD by sending the notice by certified or registered
          United States mail, return receipt requested, postage prepaid, or by
          private courier service utilizing a return receipt, addressed to
          Landlord at the address specified in Section 1.1, attention Steve
          Skilken.

          27.6.2 TO TENANT by sending the notice by certified or registered
          United States mail, return receipt requested, postage prepaid, or by
          private courier service utilizing a return receipt addressed to Tenant
          at the Premises.

     27.7 COMPLIANCE NOTICES. Within five days after receipt, Tenant shall
     advise Landlord, in writing, and provide Landlord with copies if applicable
     of any notices alleging violation(s) of the ADA or any other governmental
     requirements relating to any portion of the Premises; any claims made or
     threatened in writing regarding non-compliance with the ADA or any other
     governmental requirements; or any governmental or regulatory actions or
     investigations instituted or threatened regarding non-compliance with the
     ADA or any other Requirements; and advise Landlord of the measures Tenant
     is undertaking to remedy the situation and/or achieve compliance.

     27.8 BROKERS. After Tenant delivers a fully executed Commencement
     Agreement, Landlord will pay CB Richard Ellis a leasing commission in the
     maximum amount of $78,718.18. The commission shall be payable monthly
     during the Term in the amount of 4% of the Base Rent actually received from
     Tenant for that month. Landlord shall not be obligated to pay any monthly
     leasing commission installment unless and until it has received good funds
     in the full amount of the Base Rent due for that month. Tenant and Landlord
     each hereby certify that no real estate broker other than CB Richard Ellis
     ("Tenant's Broker") has or will represent it in this transaction, that no
     brokerage or finder's fees have been earned by any third party other than
     Tenant's Broker and that Landlord has no obligation to Tenant's Broker
     other than as set forth in this Section 27.8. Each party shall indemnify
     and hold the other party harmless from any liability or expense that may
     arise from such claims, including reasonable attorney's fees.

     27.9 NO RECORDATION. Tenant shall not record this Lease or any notice of
     this Lease, and if Tenant does so, Landlord may terminate the Lease by
     recording a Notice of Termination which shall be effective with only
     Landlord's signature appearing therein. Tenant hereby irrevocably
     constitutes Landlord its attorney-in-fact for the purpose of executing such
     instrument in recordable form.

     27.10 LANDLORD-TENANT RELATIONSHIP. Nothing contained herein shall be
     deemed or construed by the parties hereto, nor by any third party as
     creating any relationship between the parties hereto other than the
     relationship of Landlord and Tenant.

     27.11 AUTHORIZATION OF TENANT. This Lease and the instruments and documents
     contemplated hereby, and the execution and delivery hereof by Tenant, and
     the consummation of the transactions herein provided, do not violate any
     provision of the constitution or bylaws of Tenant or any agreement to which
     Tenant is a party or by which Tenant is bound, and constitute valid and
     binding obligations of Tenant enforceable against it in accordance with
     their respective terms. No consent or governmental approval is required in
     connection with the consummation of the transactions contemplated hereby.
     Tenant represents and warrants to Landlord that it has full right, power
     and authority to enter into the transactions provided for in this Lease;
     and that it has not, at any time, subleased, pledged, hypothecated,
     assigned or encumbered the Lease or in any other manner encumbered the
     Premises and will not do so. Tenant has provided evidence of authority to
     Landlord substantially in the form attached as Exhibit D.

     27.12 NO THIRD PARTY BENEFICIARY. Tenant is the individual or business
     entity whose name appears in Section 1.2 of this Lease. This Lease does not
     give any rights to any third party.

     27.13 JOINT AND SEVERAL LIABILITY. If two or more individuals,
     corporations, partnerships, limited liability companies or other business
     associations (or any combination thereof), sign this Lease as Tenant, the
     liability of each individual, corporation, partnership, limited liability
     company or other business association to pay Rent and perform all other
     obligations hereunder shall be joint and several. If a Tenant named in this
     Lease is a partnership or other business association, the members of which
     are, by virtue of statute or general law, subject to personal liability,
     the liability of each member shall be joint and several.

     27.14 EXHIBITS. All Exhibits referenced in this Lease are incorporated

                  Exhibit B    -    Commencement Agreement
                  Exhibit C    -    Tenant's Approved Signs
                  Exhibit D    -    Tenant's Authorization

     27.15 SURVIVAL OF TENANT'S OBLIGATIONS. All obligations of Tenant which, by
     their nature, involve performance in any particular after the end of the
     Term, or which cannot be ascertained to have been fully performed until
     after the end of the Term, shall survive the expiration or sooner
     termination of this Lease.

     27.16 NEGOTIATIONS. This Lease has been negotiated by Landlord and Tenant
     and this Lease, together with all the terms and provisions hereof, shall
     not be deemed to have been prepared by either Landlord or Tenant, but by
     both equally and shall be construed as an arm's length transaction. The
     respective legal counsel of the parties hereto have reviewed this Lease,
     and each has obtained the advice of its own legal counsel regarding this
     Lease and the transactions contemplated herein.

     27.17 ENTIRE AGREEMENT. This Lease, including the Exhibits and any riders
     hereto, contains all the agreements, conditions, understandings,
     representations and warranties made between the


                                    Page 22
<PAGE>

     parties hereto with respect to the subject matter hereof, and may not be
     modified orally or in any manner other than by an agreement in writing
     signed by both parties hereto or their respective successors in interest.

     27.18 NO VERBAL WARRANTIES. Tenant acknowledges and agrees that, except as
     expressly set forth in this Lease, there have been no representations or
     warranties made by or on behalf of Landlord with respect to the Premises,
     the Building or the Land with respect to the suitability of any thereof for
     the conduct of Tenant's business, present or future rents, expenses,
     profits, operations, tenancies, or any other matters. The taking of
     possession of the Premises by Tenant shall conclusively establish that the
     Premises, the Building and the Land were then in satisfactory condition,
     order and repair.

     27.19 WAIVER OF JURY TRIAL. To the extent that a waiver is permitted by
     law, Landlord and Tenant hereby knowingly, voluntarily and unconditionally
     waive trial by jury in any action, proceeding or counterclaim brought in
     connection with this Lease or any other document executed and delivered by
     either party in connection herewith, or the Premises, Building or Land.

     27.20 FINANCING CONDITION. Tenant acknowledges that the provisions of this
     Lease may require approval by the institutional lender that finances or
     refinances the purchase, construction and improvements to the Building and
     Premises (the "Institutional Lender"). If, as a condition to financing, the
     Institutional Lender requires modification of this Lease, Tenant shall
     approve the required modification provided that the modification does not
     change the dimensions or location of the Premises or the improvements that
     are a part of the Premises, or increase the Rent Tenant is obligated to pay
     hereunder. Landlord's obligations under this Lease are conditioned upon
     approval of this Lease by the Institutional Lender.

     27.21 ACKNOWLEDGMENT OF LANDLORD WAIVER. Landlord acknowledges the Waiver
     and Consent by Real Property Owner(s) made and entered into between
     Landlord and Foothill Capital Corporation on July 2, 2001 (the "Landlord
     Waiver") and agrees that the Lease (as defined in the Landlord Waiver)
     shall include this Lease. The intent of this Section 27.21 is to provide to
     Foothill Capital Corporation all of the benefits, rights and protections
     afforded by the original Landlord Waiver, notwithstanding the execution of
     this Lease.

     27.22 SIGNATURE REQUIREMENT. This document does not constitute an offer or
     option to lease and is not valid unless it is signed by and a signed copy
     delivered to both Landlord and Tenant.

IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease on the
respective dates set forth below.
