          (c) Tenant shall pay Landlord its proportionate share of Operating Costs throughout the Lease term, which proportionate share is the same proportion which the rentable square foot area of the Premises (40,440 rentable square feet) bears to the total rentable square foot area of the Building (40,440 square feet) or one hundred percent (100%) (“Tenant’s Percentage”). Tenant shall also pay Landlord its proportionate share of CAM, which shall be determined by dividing the total rentable square foot of the Building by the total rentable square foot area of all improvements within the Park (392,289 rentable square feet) and multiplying the same by Tenant’s Percentage.

          (d) Anything in this Lease to the contrary notwithstanding, Tenant shall pay to Landlord, as additional rent, an amount equal to the product obtained by multiplying the number of rentable square feet comprising the Premises by the actual cost per rentable square foot of (i) water, sewer, gas, electric and all other utility services for the Property or Park, including but not limited to utilities for the heating and cooling of the Building (both common areas and space leased to tenants), and (ii) snow and ice removal and all costs associated with such snow and ice removal. To the extent that any such costs are excluded from the calculation of Operating

Expenses or CAM or are billed separately to Tenant under this Section 5(d) or otherwise, the same shall not also be included in “Operating Expenses” or as part of “CAM” under this Section 5.

          (e) Landlord shall notify Tenant from time to time of the amount which Landlord estimates will be the amount payable by Tenant in accordance with subsections (b) and (c) above, and Tenant shall pay such amounts to Landlord in equal monthly installments, in advance, on the first day of each month, simultaneously with payments of the rent reserved pursuant to Section 2 hereof. On or before April 30 ^th of each year of the term, Landlord shall submit to Tenant a statement showing the actual amounts incurred by Landlord as set forth in subsections (b) and (c), the amount theretofore paid by Tenant, and the amount of the resulting balance due thereon, or overpayment thereof, as the case may be. In the event any balance may be due by Tenant, Tenant shall pay said balance within thirty (30) days from the date of such statement. In the event Tenant has made any overpayment, such overpayment shall be credited by Landlord against the next installment or installments of rent and Operating Costs which are due and payable hereunder, or if the term of this Lease has expired, such overpayment shall be refunded by Landlord to Tenant, without interest, within thirty (30) days after the date of such statement. Each such statement submitted by Landlord shall be final and conclusive between the parties hereto as to the matters therein set forth, if no objection is raised with respect thereto within one hundred fifty (150) days after submission of each such statement, except to the extent that (a) if an error or omission is discovered in a subsequent year which resulted in an overcharge to Tenant of five percent (5%) or more, then Tenant shall have the right, by written notice to Landlord within thirty (30) days after such overcharge is discovered, to audit Landlord’s records with respect to the preceding two Lease years, or (b) if there is fraud or misrepresentation of a material item in Landlord’s statement with respect to Operating Costs or CAM for any Lease year, Tenant shall have the right, by written notice to Landlord within thirty (30) days after Tenant’s discovery thereof, to audit Landlord’s books and records pertaining to Operating Costs and CAM for all prior Lease years.

      6. Repairs and Maintenance.

          (a) Except as expressly provided in Section 4(c), this Section 6 or Exhibit B , Landlord shall be under no liability, nor have any obligation to do any work or make any repairs in or to the Premises, and any work which may be necessary to outfit the Premises for Tenant’s occupancy or for the operation of Tenant’s business therein is the sole responsibility of Tenant and shall be performed by Tenant at its own cost and expense. Tenant acknowledges that it is in possession of the Premises and has fully inspected the Premises prior to execution of this Lease,

and that Landlord has made no warranties or representations with respect to the condition or state of repairs of the Premises except as specifically provided in this Lease. In furtherance of its obligations under Section 4(c), Landlord shall make all structural repairs to the roof, walls and foundations of the Building as needed and shall maintain and repair all Building systems (excluding Tenant’s Specialty Equipment) all common areas, grounds and land in reasonably good condition. Notwithstanding the foregoing, other than routine periodic maintenance, (i) Landlord’s responsibility for repairing any of the foregoing items shall arise only after a reasonable time has elapsed after Tenant has notified Landlord in writing of the necessity for any such repairs; and (ii) Tenant (and not Landlord) shall be responsible for the repairs of any such items if the necessity therefor was caused in whole or primarily in part by the negligent act or omission or misuse of Tenant, its agents, officers, employees, contractors, licensees, sublessees or invitees (except to the extent the cost of such work is provided through insurance maintained by Landlord under this Lease).

          (b) Tenant, at Tenant’s sole expense, shall, except for services furnished by Landlord pursuant to Section 4 and this Section 6, maintain the Premises in good order, condition, and repair, including all of Tenant’s Specialty Equipment and the interior surfaces of the ceilings, walls and floors, all doors, all interior windows, and all plumbing, pipes and fixtures, electrical wiring, switches and fixtures, building standard furnishings and special items and equipment installed by or at the expense of Tenant. Tenant’s maintenance obligations are limited to those items within its Premises and Tenant has no obligation to maintain wiring, plumbing, pipes or fixtures or other items outside the Premises (except for Tenant’s Specialty Equipment), unless the damage thereto was caused primarily by the negligent act of Tenant, its agents, officers, employees, contractors or invitees. Tenant shall also be responsible for the cost to maintain at all times in good order, condition and repair, all heating, ventilating, air conditioning and other separate climate control equipment that is installed for any computer or similar equipment, designed specifically for Tenant (e.g. for a computer or telephone room), whether the same was installed initially, or at a later date, by Landlord or by Tenant. The costs incurred by Landlord to maintain such climate control equipment shall be billed to Tenant as additional rent, and shall be payable by Tenant within thirty (30) days following receipt of the billing statement.

          (c) Tenant shall be responsible for all repairs in and to the Building the need for which arises out of (i) the moving of Tenant’s property into or out of the Building; or (ii) any negligence of Tenants, its agents, contractors, employees or invitees (except to the extent that the cost thereof is covered by insurance maintained by Landlord under this Lease).

          (d) If Tenant fails to maintain the Premises in good order, condition and repair, Landlord may give Tenant notice to do such acts as are reasonably required to so maintain the Premises. If Tenant fails to commence such work promptly and diligently prosecute it to completion, Landlord shall have the right, following not less than ten (10) days’ prior written notice to Tenant (except if such failure results in an emergency condition, the notice period may be reduced commensurate with such emergency), to do such acts and expend such funds at the expense of Tenant as are reasonably required to perform such work. Any amount so expended by Landlord shall be paid by Tenant within fifteen (15) days after demand, with interest from the date of such work, at a rate equal to the prime commercial rate of interest published by the Wall Street Journal closest to the date such work was commenced. Landlord shall have no liability to Tenant for any

damage, inconvenience or interference with the use of the Premises by Tenant as a result of performing any such work.

          (e) Tenant shall not place a load upon any floor of the Premises which exceeds the load per square foot which such floor was designed to carry two hundred pounds per square foot. Landlord reserves the right to consult with its structural engineer if necessary, in Landlord’s opinion, to resolve any questions concerning this matter, in which event the determination of the engineer shall be conclusive and the cost of any such determination shall be paid for by Tenant upon demand. Tenant shall not install business machines or mechanical equipment which cause noise or vibration to such a degree as to be reasonably objectionable to Landlord or other Park tenants.

          (f) Except as otherwise expressly provided in this Lease, Landlord shall have no liability to Tenant nor shall Tenant’s obligations under this Lease be reduced or abated in any manner whatsoever by reason of any inconvenience, annoyance, interruption or injury to business arising from Landlord’s making any repairs or changes which Landlord is required or permitted by this Lease or by any other tenant’s lease or required by law to make in or to any portion of the Building or the Premises, absent the negligent or willful acts or omissions of Landlord or Landlord’s agents, employees, contractors, invitees or licensees. Landlord shall, nevertheless, use reasonable efforts to minimize any interference with Tenant’s business in the Premises and with the use by Tenant, its agents, officers, contractors, employees and invitees of the common areas associated therewith.

          (g) As soon as is reasonably practicable after Tenant obtains actual knowledge thereof, Tenant shall give Landlord prompt notice of any damage to or defective condition in any part or appurtenance of the Building’s mechanical, electrical, plumbing, HVAC or other systems serving, located in, or passing through the Premises.

          (h) Upon the expiration or earlier termination of this Lease, Tenant shall return the Premises to Landlord broom clean and in the same condition as on the date hereof, except for all alterations that have been performed by or on behalf of Tenant (which are governed by Section 12); normal wear and tear; and condemnation or casualty loss (provided such casualty loss is not caused by the negligent act or omission of Tenant, its agents, officers, contractors, employees or invitees (except to the extent covered by insurance to be maintained under this Lease)). Any damage to the Premises, including any structural damage, resulting from Tenant’s use or from the removal of Tenant’s fixtures, furnishings and equipment shall be repaired promptly by Tenant at Tenant’s expense, except to the extent covered by Landlord’s insurance. Landlord shall bill Tenant, as promptly as is practicable, for the costs of any cleanup and/or repairs to the Premises necessitated by Tenant’s use and occupancy thereof (normal wear and tear and losses caused by Landlord’s negligence or that of its employees, invitees, agents or contractors excepted) and such costs shall constitute additional rental due and payable hereunder notwithstanding any expiration or termination of this Lease.

      7. Compliance With Laws.

Tenant covenants and agrees that it will, at its own expense, observe and comply with all laws, orders, rules, requirements and regulations of any and all governmental departments, bodies,

bureaus, agencies and officers, and all rules, directions and requirements of the local board of fire underwriters and the fire insurance rating organizations having jurisdiction over the area in which the Premises are situated, or other bodies or agencies now or hereafter exercising similar functions in the area in which the Premises are situated, in any way pertaining to the Premises or the use and occupancy thereof. Notwithstanding the foregoing, Tenant shall not be required to pay (and Landlord shall pay) the cost of any building code requirement related to capital repairs or renovations to the Building or Property except if (i) the same relates to the interior of the Premises, and (ii) any such capital repairs or renovations are required solely as the result of any alterations made by or on behalf of Tenant to the Premises after the date hereof or as a result of Tenant’s specific use. In the event Tenant shall fail to comply with any of the aforesaid laws, orders, rules, or requirements, Landlord or its agents may, following not less than ten (10) days’ prior written notice (provided that in the event of an emergency, the notice period may be decreased commensurate with the emergency), enter the Premises and take all such action and do all such work in or to the Premises as may be necessary in order to cause compliance with such laws, orders, rules or requirements, and Tenant covenants and agrees to reimburse Landlord promptly upon demand for the reasonable expenses incurred by Landlord in taking such action and performing such work.

      8. Assignment and Subletting.

          (a) Tenant covenants and agrees not to assign this Lease, in whole or in part, nor to sublet the Premises, or any part thereof, nor grant any license or concession for all or any part thereof, without the prior written consent of Landlord in each instance first had and obtained, which Landlord shall not unreasonably withhold, condition or delay. Notwithstanding the foregoing, Tenant may assign this Lease, or sublet all or any portion of the Premises to any subsidiary, affiliate or successor of Tenant, or to any person or entity that acquires substantially all the assets or capital stock of Tenant (collectively “a Related Party”) without Landlord’s prior written consent, but Tenant shall nevertheless give Landlord written notice of any such assignment or sublease within five (5) days after the effective date thereof. If any assignment or subletting is permitted pursuant to this subsection (whether or not to a Related Party), Tenant shall not be relieved from any liability whatsoever under this Lease Agreement. In the event that the amount of the rent or other consideration to be paid to Tenant by any assignee or sublessee (other than a Related Party) is greater than the rent required to be paid by the Tenant to the Landlord pursuant to this Lease after reimbursement of any reasonable costs incurred by Tenant (such as tenant’s improvements, legal fees, brokerage commissions and the like) incurred by Tenant in procuring such assignment or sublease (the “Profit”), Tenant shall pay Landlord fifty percent (50%) of the Profit when and as received by Tenant from such assignee or sublessee. Landlord shall not be entitled to any portion of the Profit in the event the assignee or sublessee is a Related Party. Any consent by Landlord to an assignment or subletting shall not constitute a waiver of the necessity of such consent as to any subsequent assignment or subletting. An assignment for the benefit of Tenant’s creditors shall not be effective to transfer or assign Tenant’s interest under this Lease unless Landlord shall have first consented thereto in writing. In the event Tenant desires to assign this Lease or to sublease more than fifty percent (50%) in the aggregate of the Premises then leased by it to a party other than a Related Party, and for fifty percent (50%) or greater of the remaining term under this Lease, then Landlord shall have the right and option to terminate this Lease, which right and option shall be exercisable by written notice from Landlord to Tenant within ten (10) business days from the date Tenant gives

Landlord written notice (“Sublet Notice”) of its desire to assign this Lease or sublet more than 50% of the Premises to other than a Related Party. In such event, the termination of this Lease shall be effective on the date that Tenant would have delivered the Premises (or a portion thereof) to the assignee or subtenant, as provided in its Sublet Notice. If Landlord fails to give timely notice of such termination election, then Landlord shall be deemed to have approved such requested sublease or assignment as requested by Tenant.

          (b) It is agreed that it shall not be a reasonable basis for Landlord to withhold permission for subletting or assignments by Tenant if Landlord (i) is negotiating with the proposed subtenant(s) of Tenant for other office space owned or controlled by Landlord, or (ii) has other office space available for rent in other buildings owned or controlled by Landlord.

          (c) Landlord agrees that it will respond to any request by Tenant for an approval of a prospective sublease or assignment within ten (10) business days of Tenant’s written request to be accompanied by (i) the name of the proposed entity to include a description of the core business and the intended use of the Premises to be assigned or subleased, (ii) reasonable and customary financial information to the extent available, (iii) a floor plan showing the intended area to be subleased or assigned, and (iv) an executed term sheet setting forth the basic terms of the prospective transaction which shall not be deemed to mean a negotiated or executed assignment or sublease agreement. If Landlord fails to give timely notice of its approval or disapproval, or termination election (if applicable), then Landlord shall be deemed to have approved such requested sublease or assignment as requested by Tenant.

      9. Increase in Landlord’s Insurance Rates.

Tenant will not do, or suffer to be done, anything in or about the Premises, or keep or suffer to be kept, anything in or about the Premises which will contravene or affect any policy of insurance against loss by fire or other hazards, including but not limited to public liability, now existing or which the Landlord may hereafter place thereon, or which will prevent the Landlord from procuring such policies in companies acceptable to Landlord at standard rates. Tenant will, at Tenant’s sole expense, take all such actions and make any installations or alterations as may be necessary to obtain reasonable insurance rates for the Premises (given its character and permitted uses) and the Building caused by the occupancy of Tenant, the nature of the business carried on by Tenant in the Premises, or otherwise resulting from any act of Tenant, its agents, servants, employees or customers, or anything done or suffered to be done by Tenant, its agents, servants, employees or customers, outside of what are permitted uses hereunder. However, any installations, alterations or improvements to the Premises which could result in a reduction in insurance rates shall only be undertaken at the sole cost of Landlord, unless the same are required as the result of any installations, alterations or improvements made by Tenant to the Premises other than those for Tenant’s intended use of the Premises.

      10. Insurance — Indemnity.

          (a) Tenant covenants and agrees that from and after the Lease Commencement Date, Tenant will carry and maintain, at its sole cost and expense and in the amounts specified and in the form hereinafter provided, the following types of insurance:

               (i) Business Personal Property insurance covering Special Causes of Loss. Such Business Personal Property insurance shall not be in an amount less than that required to replace all of the Tenant’s trade fixtures, decorations, furnishings, equipment and personal property and in an amount required to avoid the application of any coinsurance provision. Such Business Personal Property insurance shall contain a Replacement Cost valuation provision.

               (ii) Plate glass insurance covering all plate glass in the Premises (if the Premises include such glass other than ordinary windows). Tenant shall be and remain liable for the repair and restoration of all such plate glass.

               (iii) Boiler and Machinery insurance (if, at any time during this Lease, Tenant’s operations include a pressure vessel). Such Boiler and Machinery insurance will be on a Repair and Replacement basis, will be against Comprehensive perils, shall not be in an amount less than that required to replace all of the Tenant’s trade fixtures, decorations, furnishings, equipment and personal property and shall be in an amount required to avoid the application of any coinsurance provision.

               (iv) Business Income insurance covering Special Causes of Loss. Such Business Income insurance shall be in minimum amounts typically carried by prudent businesses engaged in similar operations, but in no event shall be in an amount less than the Base Rent then in effect for the Lease Year.

               (v) Commercial General Liability insurance (written on an occurrence basis) including Contractual Liability coverage insuring the obligations assumed by Tenant under this Lease, Premises and Operations coverage, Personal Injury Liability coverage, Independent Contractor’s Liability coverage. Such Commercial General Liability insurance shall be in minimum amounts typically carried by prudent businesses engaged in similar operations, but in no event shall be in an amount less than Two Million Dollars ($2,000,000) combined single limit per occurrence with a Three Million Dollar ($3,000,000) annual aggregate. If the nature of Tenant’s operations are automobile-related, Tenant may satisfy this requirement with Garage Liability insurance with limits of not less than Two Million Dollars ($2,000,000) per accident for Auto, Two Million Dollars ($2,000,000) per accident for other-than-Auto and a Three Million Dollars ($3,000,000) annual aggregate for other-than-Auto. If Tenant conducts operations at locations and/or projects other than the Premises, such annual aggregate limit will be expressed on a “per location” and/or “per project” basis, as the case may be. If the nature of Tenant’s operations are such that Tenant has seniors, children, developmentally-disabled or other vulnerable people in its care or if such people are in the Tenant’s care incidental to the Tenant’s operations, Tenant’s Commercial General Liability insurance shall not exclude coverage for Sexual Abuse and/or Molestation. Such Commercial General Liability insurance shall be primary to — and non-contributory with — any similar insurance maintained by Landlord.

               (vi) Workers’ Compensation insurance including Employer’s Liability insurance. Such Workers’ Compensation insurance shall be for the statutory benefits which may, from time to time throughout the term of this Lease, become payable

in the jurisdiction in which the Premises are located. Such Employer’s Liability insurance shall be in amounts not less than One Hundred Thousand Dollars ($100,000) for each accident, Five Hundred Thousand Dollars ($500,000) as a policy limit for disease and One Hundred Thousand Dollars ($100,000) per employee for disease. Such Workers’ Compensation insurance will include a Waiver of Subrogation in favor of Landlord.

          (b) All such insurance shall: (1) be issued by a company that is “Admitted” to do business in the jurisdiction in which the Premises are located, that has been approved in advance by Landlord and that has a rating equal to or exceeding A: IX from A.M. Best Company; (2) (except for Workers’ Compensation and Employer’s Liability) name Landlord, the managing agent of the Building (if any) and the holder of any Mortgage as Additional Insureds/Loss Payees, as applicable; (3) contain an endorsement prohibiting cancellation or failure to renew without the insurer first giving Landlord thirty (30) days’ prior written notice (by certified or registered mail, return receipt requested) of such proposed action (no less than ten [10] days’ notice of cancellation or failure to renew for non-payment of premium).

          (c) No such Commercial General Liability, Automobile Liability, Workers’ Compensation or Employer’s Liability insurance shall contain a self-insured retention provision except as otherwise approved in writing by Landlord, which approval shall not be unreasonably withheld. Landlord reserves the right from time to time to require Tenant to obtain higher minimum amounts or different types of insurance if it becomes customary for other landlords of similar buildings as that which contains the Premises to require similar-sized tenants in similar industries to carry insurance of such higher minimum amounts or of different types. At the commencement of this Lease, Tenant shall deliver a certificate of all required insurance and will continue throughout the term of this Lease to do so not less than ten (10) days prior to the expiration of any required policy of insurance. Neither the issuance of any insurance policy required under this Lease nor the minimum limits specified herein shall be deemed to limit or restrict in any way Tenant’s liability arising under or out of this Lease.

          (d) All insurance shall provide that the insurer thereunder waives all right of recovery by way of subrogation against Landlord, its partners, employees, agents, representatives and any other party required to be the recipient of such a waiver under the terms of any written contract or agreement with Landlord pertaining to this Lease and/or to the Premises, in connection with any loss or damage covered by such policy. Tenant shall, and does hereby, indemnify and hold harmless Landlord from and against any and all liabilities, fines, claims, damages and actions, costs and expenses of any kind or nature (including reasonable attorneys’ fees) (i) relating to or arising from the use and occupancy of the Premises; (ii) due to or arising out of any mechanic’s lien filed against the Building, or any part thereof, for labor performed or for materials furnished or claimed to be furnished to Tenant, or (iii) due to or arising out of any breach, violation or nonperformance of any covenant, condition or agreement in this Lease set forth and contained on the part of Tenant to be fulfilled, kept, observed or performed, unless such damage or injury shall be occasioned by the negligence or willful act or omission of the Landlord or Landlord’s agents, employees, contractors, invitees or licensees, in which event, Landlord shall indemnify and hold harmless Tenant to the extent of such negligence or willful act or omission. Notwithstanding the foregoing, Tenant shall at all times remain liable for, and indemnify and

hold harmless Landlord as aforesaid, against any damage or injury arising from perils against which Tenant is required by this Lease to insure, regardless of the negligence, act or omission of others.

          (e) Landlord covenants and agrees that from and after the Lease Commencement Date of this Lease, Landlord will carry and maintain (subject to reimbursement as an Operating Expense) and in the amounts specified and in the form hereinafter provided, the following types of insurance:

          (i) Fire and Extended Coverage. Fire and extended coverage insurance covering the Building and the Property and any alterations, improvements, additions or changes made by Landlord thereto in an amount not less than one hundred percent (100%) of their full replacement cost from time to time during the Lease term, providing protection against special causes of loss as defined within the property insurance form promulgated by the Insurance Services Office, Inc. Such insurance shall be on an agreed value (no coinsurance) basis and shall have a deductible of not more than Twenty-Five Thousand Dollars ($25,000.00).

          (ii) Commercial General Liability. Commercial general liability insurance covering the Building and the Property and Landlord’s use thereof against claims for bodily injury or death and property damage occurring upon, in or about the Property, such insurance to afford protection to the limit of not less than Two Million Dollars ($2,000,000.00) arising out of anyone occurrence. The insurance coverage required under this Section 10(e)(ii) shall, in addition, extend to any liability of Landlord’s arising out of Landlord’s indemnities hereinafter provided, as well as independent contractors’ liability, products/completed operations liability, personal injury liability and contractual liability.
