2.2 Common Area Maintenance Charges . The Fixed Minimum Rent payable hereunder includes Tenant’s Proportionate Share (as hereinafter defined) of all costs and expenses associated with Common Area Maintenance Charges (“C.A.M.”) incurred by Landlord during the calendar year 2005 (“Base Year”) in connection with the ownership, management, maintenance, repair and operation of Landlord’s Property, including, without limitation, a heating, ventilating and air-conditioning annual service agreement; maintaining, repairing, replacing, striping and sweeping parking lots, driveways and private roads, loading areas and easement areas; all electricity, sewer, water and other utility costs in connection with the Common Areas not separately metered to tenants; sewer and water usage for the Premises; landscape maintenance and replacement, snow removal; dumpster service; costs and expenses incurred by Landlord in protesting Taxes (as hereinafter defined), and all other items reasonably necessary for the operation or preservation of Landlord’s Property in a first-class condition, including any replacement or structural reserves; the cost of providing the fire monitoring for the Premises as provided by Silent Security Signal, a Division of Cleveland Security Patrol; and an administration fee equal to seven and one-half percent (7.5%) of the foregoing costs. In the event that the Landlord’s costs and expenses associated with C.A.M. exceeds the amount payable during the Base Year, then in such event, Tenant shall pay to Landlord in equal monthly installments, in advance with payments of Fixed Minimum Rent, an amount equal to one-twelfth (1/12 ^th ) of the estimated amount of Tenant’s Proportionate Share of C.A.M. Notwithstanding the foregoing, if Landlord’s costs and expenses associated with C.A.M. exceed the amount payable during the Base Year, in no event shall Tenant’s Proportionate Share of C.A.M. be increased during any Lease Year more than one percent (1%) per annum.

2.3 Utilities . The Fixed Minimum Rent payable hereunder includes all electricity, gas and any other utilities furnished to the Premises during the term hereof. Landlord shall have no liability to Tenant or any other party for any interruption in utility services or for the failure to furnish same.

2.4 Taxes and Assessments . The Fixed Minimum Rent payable hereunder includes Tenant’s Proportionate Share of all real estate taxes or assessments, both general and special (collectively, “Taxes”), levied upon the Property during the calendar year 2005 (“Base Year”) based upon an amount of One and 50/100ths Dollars ($1.50) per square foot per annum. Subject to the limitation hereinafter provided, in the event that the amount of Taxes payable during the term of this Lease exceed the amount of Taxes payable during the Base Year, then in such event Tenant shall pay to Landlord in equal monthly installments, in advance with payments of fixed minimum rent, an amount equal to one-twelfth (1/12) of the estimated amount of Tenant’s Proportionate Share of Taxes. Within thirty (30) days after the actual amount of Tenant’s Proportionate Share of Taxes has been determined by Landlord, based on the actual Taxes, Landlord shall notify Tenant and Tenant shall pay to Landlord or Landlord shall credit to Tenant’s account for future payments of Taxes, as the case may be, the difference between the estimated amount of Tenant’s Proportionate Share of Taxes

theretofore paid to Landlord for such year and the actual amount of Tenant’s Proportionate Share of Taxes for such year. Notwithstanding the foregoing, if Landlord’s costs and expenses associated with Taxes exceed the amount payable during the Base Year, in no event shall Tenant’s Proportionate Share of Taxes be increased during any Lease Year more than one percent (1%) per annum. The amount payable by Tenant pursuant to this Section 2.4 for the year in which this Lease commences or terminates shall be prorated based on the ratio of that portion of the term of this Lease to the applicable tax year.

Subject to Section 3.2(a) hereof, Tenant shall take possession of the Premises in its “as-is” condition as of the Commencement Date, shall not permit the Premises to be vacant during the term of this Lease and at the end of the term of this Lease or on the earlier termination hereof, shall deliver all keys to Landlord and leave and deliver the Premises to Landlord broom clean and in good condition and repair, reasonable wear and tear only excepted.

3.2 Construction of Improvements .

(a) Landlord shall make the improvements to the Premises, if any, described as Landlord’s Work (“Landlord’s Work”) on Exhibit C attached hereto and made a part hereof. Landlord shall use reasonable efforts to substantially complete Landlord’s Work on or before the Commencement Date and shall provide Tenant notice of the occurrence thereof, but shall not be responsible for delays due to (i) causes beyond Landlord’s reasonable control, (ii) any act, delay or failure to act of Tenant, (iii) any changes requested by Tenant in Landlord’s Work or any work performed or to be performed by Tenant, (iv) the quality of performance or completion of any work by a person, firm or corporation employed by Tenant, (v) the work being performed by or on behalf of Tenant which, under good construction scheduling practices should be completed before portions of the Landlord’s Work are completed, is not completed by Tenant on schedule and/or results in delays in the completion of Landlord’s Work, and/or (vi) any other act or omission of Tenant, its agents, employees, or contractors, including, without limitation, any delay in giving authorization or approvals (in any instance, a “Tenant Delay”). Tenant shall be entitled, as Tenant’s sole remedy, to an abatement of the Fixed Minimum Rent otherwise due hereunder for any period following the Commencement Date during which the Premises remain unavailable for occupancy by Tenant because of Landlord’s failure to substantially complete Landlord’s Work; provided, however, that if Landlord, in Landlord’s sole judgment, is delayed in timely substantially completing Landlord’s Work because of any Tenant Delay, then there shall be no abatement of the Fixed Minimum Rent for the period of such Tenant Delay. Except for the abatement of the Fixed Minimum Rent as set forth in the previous sentence, Tenant waives and releases any and all claims for damages against Landlord resulting from the Premises remaining unavailable for occupancy by Tenant due to Landlord’s failure to substantially complete Landlord’s Work. The taking of possession of the Premises by Tenant shall be deemed conclusively to establish that Landlord’s Work has been completed and accepted by Tenant.

(b) On or before the Commencement Date, Tenant shall, at its sole cost and expense, supply all installations and complete the improvements and other work, if any, described as Tenant’s Work (“Tenant’s Work”) on Exhibit C , and shall fully equip the Premises with all trade fixtures, lighting fixtures, furniture, furnishings, fixtures, floor coverings, signs, special equipment and other items of construction and personal property necessary for the completion of the Premises and the proper operating of Tenant’s business therein.

(c) Tenant shall not undertake, directly or indirectly, Tenant’s Work or any other construction work, improvements or alterations (collectively, “Alterations”), nor shall Tenant install any equipment other than trade fixtures and personal property, in the Premises without first obtaining Landlord’s written approval of the plans and specifications (“Plans”) therefor. Within thirty (30) days after the execution of this Lease, Tenant shall submit the Plans to Landlord showing in detail the Alterations Tenant is required or desires to undertake in the Premises. The Plans shall be prepared at Tenant’s sole cost and expense by an engineer or architect of recognized competence, licensed to practice in the State of Ohio and otherwise acceptable to Landlord. Tenant shall revise the Plans in accordance with and within seven (7) days after receipt of Landlord’s comments. Tenant, at Tenant’s sole cost and expense, shall obtain all building, use and occupancy permits and licenses required by applicable governmental authorities for the Alterations, for the use of the Premises and for the conduct of Tenant’s business. Tenant shall make such changes to the Plans as may be required to conform the same to the laws and ordinances applicable to the Alterations. Landlord’s approval of the

Plans shall not constitute the assumption of any liability on the part of Landlord for their accuracy or conformity with building codes or any other legal requirements.

(d) The Alterations performed at the Premises by or on behalf of Tenant, including, without limitation, Tenant’s Work, whether in the nature of erection, construction, alteration or repair, shall be performed with new materials and completed in a first-class and workmanlike manner, promptly, efficiently and competently by duly qualified and, if required by Landlord, licensed persons or entities, without interference with or disruption of the operations of other tenants or users of Landlord’s Property, and in accordance with all applicable laws, ordinances, rules, regulations and requirements of any governmental authority having jurisdiction over the Premises, including, without limitation, the Americans with Disabilities Act of 1990, as amended. Subject to Section 3.3 hereof, the Alterations shall at once when made or installed be deemed to have attached to the freehold estate and become the property of Landlord and, except as otherwise provided herein, shall remain for the benefit of Landlord at the end of the term or other termination of this Lease in as good condition and repair as when installed, reasonable wear and tear excepted, and Tenant shall not be entitled to any payment or compensation therefor.

3.3 Trade Fixtures . If Tenant is not then in default hereunder, all trade fixtures, personal property and/or equipment installed in the Premises by Tenant may, and if Landlord so requests shall (together with any other Alterations made to the Premises by or for the benefit of Tenant if directed by Landlord to do so), be removed by Tenant at the end of the term or other termination of this Lease and Tenant shall immediately repair, at Tenant’s sole cost and expense, any injury to the Premises resulting from such installation or removal. If Tenant removes lighting fixtures, then Tenant shall restore and leave in operating order and with operating bulbs or tubes the equivalent of the lighting equipment in the Premises as of the Commencement Date.

3.4 Alterations . Tenant shall not make any Alterations nor shall Tenant cause or permit any equipment or apparatus to be installed or put upon or through the roof, walls or floors of the Premises without Landlord’s written consent. Any permitted Alterations to or installations in the Premises shall be effected by Tenant, lien free without cost to Landlord and subject to the requirements of Sections 3.2(c) and (d) hereof.

3.5 Signs . Tenant shall not place any signs on the exterior of the Premises without Landlord’s written consent, which consent shall not be unreasonably withheld, w
