Notwithstanding the foregoing, if such failure to provide services is caused by Landlord’s negligence or willful misconduct and shall continue for five (5) consecutive days, then all rent shall be abated from the sixth (6^th) day until such services are fully restored.

5. Operating Costs.

(a) “Operating Costs” are the reasonable costs of managing, operating, maintaining, repairing, refurbishing and insuring the Building and all common areas and facilities within the Property (including, but not limited to, elevators, stairwells, loading areas, parking areas, pavements and walkways, landscaping, gardening, storm drainage, and other utility systems); the cost of utilities for such common areas and facilities; fire protection and security services, if any; traffic control equipment; repairs; parking lot striping; lighting; sanitary control; janitorial services; removal of trash, rubbish, garbage and other refuse; depreciation on or rentals of machinery and equipment used in such maintenance over its useful life on a straight line basis; the cost of personnel on-site to implement such services; all insurance of whatsoever nature kept, or caused to be kept, by Landlord out of or in connection with the ownership of the Building and common areas, including, but not limited to, insurance insuring the same against loss or damage by, or abatement of rental income resulting from, fire and other such hazards, casualties, and contingencies, and liability and indemnity insurance; plus the actual administrative and overhead costs of Landlord’s on-site building engineer, building manager or maintenance worker in conformance with Landlord’s current practice as of the date of this Lease. Such costs shall not include (i) the cost of any capital improvements or capital expenditures in or to the Building, the Property or the Premises as determined under generally accepted accounting principles; (ii) work which Landlord performs specifically for or at the expense of any other tenant of the Building; (iii) maintenance of the HVAC system serving the Premises and maintenance of any other HVAC systems serving other portions of the Building; (iv) trash removal from the dumpster located on the exterior of the Building; (v) costs related to ground rent, interest or debt service; (vi) penalties, fines or late charges, or any other costs which may be incurred as the result of the negligent or willful misconduct of Landlord or Landlord’s agents, employees, invitees, licensees and contractors; (vii) any amounts payable to Landlord or any affiliate of Landlord, except payment for services rendered where the charges for such services are reasonably commensurate with the charges for similar services provided by similarly qualified persons in the geographical location in which the Property is located; (viii) management fees in excess of four percent (4%) of gross rent received by Landlord; (ix) depreciation;

The foregoing shall apply to real estate taxes assessed against the common areas or Building generally, and resulting from any improvements placed thereon by Tenant. “Taxes” as used herein shall also include, but not by way of limitation, all paving taxes, special paving taxes, special taxing district assessments and any and all other benefits or assessments which may be levied on the Property or the Building, but shall not include any income tax (on the income or rent payable hereunder or otherwise), and shall not include taxes or assessments related to other buildings or improvements located within the Property, franchise, transfer, inheritance or capital stock taxes. “Taxes” shall also include all reasonable expenses incurred by Landlord (including reasonable attorneys’ fees and costs) in contesting any increase in, or applying for any reduction of, a tax assessment.

(b) “CAM” shall mean the total costs incurred by Landlord for the operation, maintenance, repair, insuring and management of all common facilities within Landlord’s entire property, consisting of approximately forty-three (43) acres (the “Park”) including, but not limited to, common roads, snow removal, lighting of common areas, Taxes payable by Landlord, or its successors, with respect thereto and other similar operational and maintenance expenses. CAM shall not include any Operating Costs incurred or payable in connection with any other buildings (and their adjacent parking and common areas) within the Park, it being intended that CAM shall include only such costs which are incurred by Landlord for the common benefit of all tenants of the Park, such as access roads, illumination thereof, etc.

(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 (60,178 rentable square feet) bears to the total rentable square foot area of the Building (60,178 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.

(f) Notwithstanding any of the foregoing provisions of this Section 5, (i) Operating Costs, as used herein, shall be allocated only to the Building and all land and common area and facilities, including parking areas, which are directly adjacent, allocated and dedicated to the Building, (ii) the allocation of all direct and indirect personnel costs shall be equitably spread across all of the buildings and sites in the entire Park, and not just against the leased portions of the buildings in the Park, (iii) the allocation of CAM fees shall not be charged or allocated against vacant office space in the Park, and (iv) Tenant shall have thirty (30) days from the date of Tenant’s receipt of the year end invoice to pay its pro rata share of Operating Costs and CAM.

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 the Tenant’s Speciality Equipment), all common areas, grounds and land in reasonably good condition. Notwithstanding the foregoing, other than routine periodic maintenance, Tenant (and not Landlord) shall be responsible for the repairs of any items if the necessity therefor was caused in whole or primarily in part by the gross 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 the Tenant’s Speciality Equipment and the interior surfaces of the ceilings, walls and floors and all doors and all interior windows. Tenant shall also be responsible for the cost to maintain at all times in good order, condition and repair, the Tenant’s Speciality Equipment, whether the same was installed initially, or at a later date, by Landlord or by Tenant. The costs incurred by Landlord to maintain such LAN HAVAC (if not properly maintained by Tenant) 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 xxxx 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.

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.

(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.

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.

Tenant shall promptly pay any franchise, minor privilege or other tax or assessment resulting directly or indirectly from any alterations or improvements made by Tenant to the Premises. Tenant shall repair promptly, at its own expense, any damage to the Premises or Building caused by bringing into the Premises any property for Tenant’s use, or by the installation or removal of such property, regardless of fault or by whom such damage shall be caused.

(ii) At any time after an Event of Default, without further notice except as provided in Section 13(a) hereof, to declare this Lease terminated and enter the Premises with or without legal process; and in such event Landlord shall have the benefit of all provisions of law now or hereafter in force respecting the speedy recovery of possession from Tenant’s holding over or proceedings in forcible entry and detainer, and Tenant waives any and all provisions for notice under such laws; and

In the event any action is brought to enforce or interpret the provisions of this Lease, the court shall award the prevailing party in such action reasonable attorneys’ fees and costs sufficient to reimburse the prevailing party for all costs incurred in connection with such action and the preparation for such action.

Notwithstanding the foregoing, in the event such fire or other casualty damages or destroys any of Tenant’s leasehold improvements, alterations, betterments, fixtures or equipment, Tenant shall cause the same to be repaired or restored at Tenant’s sole cost and expense and Landlord shall have no liability for the restoration or repair thereof.

Tenant further agrees to maintain any sign, billboard, marquee, awning, decoration, placard, or advertising matter or other thing of any kind as may be approved by Landlord in good condition and repair at all times.

20. Right of Entry.

Landlord and its agents, servants, employees, including any builder or contractor employed by Landlord, shall have the absolute and unconditional right, license and permission, at any and all reasonable times, to enter and inspect the Premise or any part thereof, and at the option of Landlord, to make such reasonable repairs and/or changes in the Premises as Landlord may deem necessary or proper and/or to enforce and carry out any provision of this Lease, between the hours of 9:00 A.M. and 5:00 P.M. on any day except Sunday or any legal holiday on which Tenant shall not be open for business, upon reasonable prior notice to Tenant and provided that Tenant is afforded a reasonable opportunity to provide an escort should the nature of Tenant’s business so require. Notwithstanding the foregoing, if Landlord’s entry is required because of a dangerous or emergency condition requiring immediate attention, the provisions of the foregoing sentence shall not prohibit Landlord’s immediate entry into the Premises, so long as Landlord gives Tenant such notice as may be reasonable under the circumstances.

21. Termination of Term.

(a) It is agreed that the term of this Lease shall expire and terminate at the end of the original term hereof (or at the expiration of the last renewal term, if this Lease contains a renewal option and the same is properly exercised), without the necessity of any notice by or to any of the parties hereto, unless otherwise provided herein. If Tenant shall occupy the Premises after such expiration or termination, it is understood that Tenant shall hold the Premises as a tenant from month-to-month, subject to all the other terms and conditions of this Lease, at an amount equal to one hundred fifty percent (150%) of the highest monthly rental installment reserved in this Lease, plus all additional rent required under this Lease. Landlord shall, upon such expiration or termination of this Lease, be entitled to the benefit of all public general or local laws relating to the speedy recovery of possession of lands and tenements held over by tenants that may be now in force or may hereafter be enacted.

(b) At the time Tenant surrenders the Premises to Landlord, the Premises shall be in compliance, to the best of Tenant’s actual knowledge, with all applicable building code requirements insofar as such requirements relate to Tenant’s use and occupancy of the Premises or to any installations, alterations or improvements made by Tenant thereto.

22. Condemnation.

(a) If, during the term of this Lease, all or a substantial part of the Premises shall be taken by police power or under power of eminent domain, this Lease shall terminate as of, and the rent (basic and additional) shall be apportioned to and xxxxx from and after, the date of taking. Except as provided in Section 22(d) below, Tenant shall have no right to participate in any award or damages for such taking and hereby assigns all of its right, title and interest therein to Landlord. For the purposes of this subsection, “a substantial part of the Premises” shall mean such part that the remainder thereof is rendered inadequate for Tenant’s business and that such remainder cannot practicably be repaired and improved so as to be rendered adequate to permit Tenant to carry on its business with substantially the same efficiency as before the taking.

(b) If, during the Lease term, less than a substantial part of the Premises (as hereinabove defined) is taken by police power or under power of eminent domain, this Lease shall remain in full force and effect according to its terms; and except as provided in Section 22(d) below, Tenant shall have no right to participate in any award or damages for such taking and tenant hereby assigns all of its right, title and interest in and to the award to Landlord. In such event Landlord shall, at its expense, promptly make such repairs and improvements as shall be necessary to make the remainder of the Premises adequate to permit Tenant to carry on its business to substantially the same extent and with substantially the same efficiency as before the taking; provided that in no event shall Landlord be required to expend an amount in excess of the award received by Landlord for such taking. If Landlord does not substantially complete the making of such repairs or improvements within one hundred twenty (120) days from the date of the taking, Tenant shall have the right to terminate this Lease provided Tenant gives Landlord written termination notice after the expiration of such one hundred twenty (120) day period, so long as such notice is given prior to Landlord’s substantial restoration of the Premises as aforesaid. If, as a result of such taking, any part of the Premises is rendered permanently unusable, the basic annual rent reserved hereunder shall be reduced in such amount as may be fair and reasonable, which amount

shall not exceed the proportion which the area so taken or made unusable bears to the total area which was usable by Tenant prior to the taking. If the taking does not render any part of the Premises unusable, there shall be no abatement of rent.

(c) For purposes of this section, “taking” shall include a negotiated sale or lease and transfer of possession to a condemning authority under bona fide threat of condemnation for public use, and Landlord alone shall have the right to negotiate with the condemning authority and conduct and settle all litigation connected with the condemnation. As hereinabove used, the words “award or damages” shall, in the event of such sale or settlement, include the purchase or settlement price.

(d) Nothing herein shall be deemed to prevent Tenant from claiming and receiving from the condemning authority, if legally payable, compensation for the taking of Tenant’s own tangible property and such amount as may be payable by statute or ordinance toward Tenant’s damages for Tenant’s loss of business, removal and relocation expenses, as well as any other damages for loss of its Lease (including compensation for any increased rent that Tenant shall incur as a result of relocation) so long as such other amounts do not reduce or in any manner adversely affect Landlord’s entitlement or ability to obtain the amounts to which Landlord would otherwise be entitled as compensation under applicable law.

23. Subordination; Non-Disturbance.

This Lease shall be subject to and subordinate at all times to the lien of any mortgages and/or deeds of trust upon the Building and Property now or hereafter to be made, unless the mortgagee or holder of the deed of trust elects to have Tenant’s interest hereunder superior to the interest of the mortgagee or holder of such deed of trust, so long as the mortgagee or holder of such deed of trust agrees to a subordination, non-disturbance and attornment agreement in form and substance reasonably satisfactory to Tenant, which includes provisions which permit Tenant to remain in possession following any foreclosure or other action by such lender, with all of Tenant’s rights hereunder remaining in full force and effect so long as no Event of Default has occurred under the provisions of this Lease. The Tenant agrees to execute any documents necessary, subsequent to the execution of this Lease, which are required to effect such subordination.

24. Attornment.

(a) If Landlord assigns this Lease or the rents hereunder to a creditor as security for a debt, Tenant shall, after notice of such assignment and upon demand by Landlord or the assignee, pay all sums thereafter becoming due to Landlord hereunder either to Landlord or to such assignee, as required by such notice. Tenant shall also, upon receipt of such notice, have all policies of insurance required hereunder endorsed so as to protect the assignee’s interest as it may appear and shall deliver such policies, or certificates thereof, to the assignee.

(b) In the event the Premises are sold at any foreclosure sale or sales, by virtue of any judicial proceedings or otherwise, this Lease shall continue in full force and effect and Tenant agrees, upon request, but subject to the provisions of Section 23, to attorn to and acknowledge the foreclosure purchase or purchasers at such sale as the landlord hereunder.

25. Notices to Mortgagee.

Tenant agrees that a copy of any notice of default from Tenant to Landlord shall also be sent to the holder of any mortgage or deed of trust on the Premises, provided Tenant has been given written notice of the fact that such mortgage or deed of trust has been made; and Tenant shall allow said mortgagee or holder of the deed of trust a reasonable time, not to exceed ninety (90) days from the receipt of said notice, to cure, or cause to be cured, any such default. If such default cannot reasonably be cured within the time specified herein, then such additional time as may be necessary shall be allowed, provided the curing of such default is commenced and diligently pursued (including, but not limited to, commencement of foreclosure proceedings if necessary to effect such cure) in which event this Lease shall not be terminated while such remedies are being thus diligently pursued.

26. Estoppel Certificate.

Tenant shall, at any time and from time to time during the term of this Lease or any renewal thereof, upon request of Landlord, execute, acknowledge, and deliver to Landlord (or its designee) a statement in writing, certifying that this Lease is unmodified and in full force and effect if such is the fact (or if there have been any modifications thereof, that the same is in full force as modified and stating the modifications) and the dates to which the rents and other charges have been paid in advance, if any. Any such statement delivered pursuant to this section may be relied upon by any prospective purchaser of the estate of Landlord or by the mortgagee or any assignee of any mortgagee or the trustee or beneficiary of any deed of trust constituting a lien on the Premises or the Building.

27. Landlord’s Right to Perform Tenant’s Covenants.

(a) If Tenant shall fail to perform any covenant or duty required of it by this Lease or by law, Landlord shall have the right (but not the obligation) to perform the same if Tenant has not done so, subject to the same notice requirements and other terms and conditions set forth in Section 13(a)(ii) of this Lease, and if necessary to enter the Premises for such purposes without notice. The reasonable cost thereof to Landlord shall be deemed to be additional rent hereunder payable by Tenant, shall be due and payable by Tenant upon demand, and Landlord shall have the same rights and remedies with respect to such additional rent as Landlord has with respect to the rental reserved hereunder.

(b) If Landlord shall fail to perform any covenant or duty required of it by this Lease or by law, Tenant shall have the right (but not the obligation) to perform the same if Landlord has not done so, subject to the same notice requirements and other terms and conditions set forth in Section 13(e) of this Lease.

28. Non-Waiver of Future Enforcement.

The receipt of rent by Landlord, with knowledge of any breach of this Lease by Tenant or of any default on the part of Tenant in the observance of performance of any of the conditions or covenants of this Lease, shall not be deemed to be a waiver of any provision of this Lease, including the provision breached. No failure on the part of Landlord or of the Tenant to enforce any covenant or provision herein contained nor any waiver of any right hereunder by Landlord or

Tenant shall discharge or invalidate such covenant or provision or shall affect the right of Landlord or Tenant to enforce the same in the event of any subsequent default. The receipt by Landlord of any rent or any sum of money or any other consideration hereunder paid by Tenant after the termination, in any manner, of the term herein demised, or after the giving by Landlord of any notice hereunder to effect such termination, shall not reinstate, continue or extend the term herein demised, or destroy, or in any manner impair the efficacy of any such notice of termination as may have been given hereunder by Landlord to Tenant prior to the receipt of any such sum of money or other consideration, unless so agreed to in writing and signed by Landlord. Neither acceptance of the keys nor any other act or thing done by Landlord or any agent or employee during the term herein demised shall be deemed to be an acceptance of a surrender of the Premises, excepting only an agreement in writing signed by Landlord accepting or agreeing to accept such surrender.

29. Personal Property Taxes.

Tenant shall be responsible for and shall pay any taxes or assessments levied or assessed during the term of this Lease against any leasehold interest of Tenant or personal property or trade fixtures of Tenant of any kind, owned by Tenant or placed in, upon or about the Premises by Tenant.

30. Recordation of Lease.

Tenant or Landlord may request that the parties execute a memorandum of this Lease in a form suitable for recording under applicable Virginia law. The party requesting such recording of such Memorandum of Lease shall pay all costs of recordation, including any transfer or recordation taxes thereon.

31. Severability.

(a) It is agreed that, for the purpose of any suit brought or based on this Lease, this Lease shall be construed to be a divisible contract, to the end that successive actions may be maintained thereon as successive periodic sums shall mature or be due hereunder, and it is further agreed that failure to include in any suit or action any sum or sums then matured or due shall not be a bar to the maintenance of any suit or action for the recovery of said sum or sums so omitted. Tenant agrees that it will not, in any suit or suits brought or arising under this Lease for a matured sum for which judgment has not previously been obtained or entered, plead, rely on or interpose the defenses of res adjudicata, former recovery, extinguishment, merger, election of remedies or other similar defense as a default said suit or suits.

(b) If any term, clause or provision of this Lease is declared invalid by a court of competent jurisdiction, the validity for the remainder of this Lease shall not be affected thereby but shall remain in full force and effect.

32. Non-Waiver.

It is understood and agreed that nothing herein shall be construed to be a waiver of any of the terms, covenants or conditions herein contained, unless the same shall be in writing, signed by the party to be charged with such waiver, and no waiver of the breach of any covenant herein shall be construed as a waiver of such covenant or any subsequent breach thereof. No mention in this Lease of any specific right or remedy shall preclude Landlord from exercising any other right or from having any

other remedy or from maintaining any action to which it may be otherwise entitled either at law or in equity.

33. Successors and Assigns.

(a) Except as herein provided, this Lease and the covenants and conditions herein contained shall inure to the benefit of and be binding upon Landlord, its successors and assigns; and shall be binding upon Tenant, its successors and assigns, including without limitation any trustee in bankruptcy or debtor-in-possession and any assignee of the same; and shall inure to the benefit of Tenant and its Related Parties as set forth in Section 5 hereof, as well as any assignees of Tenant to whom an assignment by Tenant has been consented to in writing by
Landlord.

(b) In the event Landlord’s interest under this Lease is transferred or assigned and written notice thereof is given to Tenant, Landlord (or any subsequent assignee or transferee of Landlord’s interest under this Lease who gives such notice to Tenant) shall automatically be relieved and released from and after the date of such transfer or conveyance from all liability hereunder. Further, the liability of Landlord, its successors and assigns, under this Lease shall at all times be limited solely to Landlord’s interest in the land and improvements comprising the Building (including rents; insurance and condemnation proceeds; and the proceeds of any sale or financing) and in the event the owner of Landlord’s interest in this Lease is at any time an individual, partnership, joint venture or unincorporated association, Tenant agrees that such individual or the members or partners of such partnership, joint venture or unincorporated association shall not be personally or individually liable or responsible for the performance of any of Landlord’s obligations hereunder.

34. Security Deposit.

(a) The parties hereby acknowledge that Landlord is holding a security deposit in the amount of Fifty Thousand Dollars ($50,000.00) pursuant to the Original Lease. The Landlord agrees that it will accept the transfer of the existing $50,000.00 deposit under the Original Lease as the new deposit required under this Section 34(a), to secure the faithful performance of Tenant’s obligations under this Lease. Notwithstanding the foregoing, in the event the amount of the security deposit held by Landlord for the Original Lease is less than $50,000.00 at the time of the Lease Commencement Date under this Lease, Tenant shall immediately pay such difference to Landlord so that the full amount of the Security Deposit is being held by Landlord under this Lease.

(b) The parties hereby agree that if the net worth of the Tenant declines to an amount equal to Five Hundred Million Dollars ($500,000,000.00) or less at anytime during the term of this Lease, the Tenant shall immediately deliver to Landlord an additional security deposit of Fifty Thousand Dollars ($50,000.00), for a total security deposit of One Hundred Thousand Dollars ($100,000.00). Tenant agrees to deliver to Landlord each year during the term hereof a copy of Tenant’s annual report or such other documentation that sets forth the net worth of the Tenant. Tenant agrees that Landlord shall have the right, but not the obligation, in its sole discretion, after five (5) days’ prior notice to Tenant, to apply said security deposit or any portion thereof to cure or remedy any Event of Default by Tenant hereunder, including but not limited to default in payment of rent and additional rent, or to reimburse Landlord for costs incurred by Landlord if Tenant fails

to restore the Premises at the end of the term to its condition existing at the commencement of this Lease, subject to ordinary wear and tear, casualty and condemnation, to the extent required under Section 12 above. Said sum, if not sooner applied, shall be returned to Tenant, without interest, within ten (10) days after vacating of the Premises by Tenant and termination of this Lease (or upon termination of the last renewal term of this Lease if this Lease contains a renewal option and Tenant properly exercises said option), provided that Landlord shall nevertheless have the right to draw upon the security deposit in such amounts as reasonably required for any damages sustained by Landlord if (i) Tenant is then in default under any of the provisions of this Lease, or (ii) there is damage to the Premises beyond ordinary wear and tear and the Premises have not been left in a clean condition and in good order with all debris, rubbish and trash placed in proper containers.

(c) If Tenant provides a Letter of Credit in lieu of cash hereunder (which Letter of Credit must be in form and substance reasonably acceptable to Landlord), and Landlord draws upon the Letter of Credit and uses all, or any portion, of the proceeds thereof to cure any default by Tenant under this Lease, Tenant agrees to deposit with Landlord, within fifteen (15) days after Landlord’s written request, a cash sum or letter of credit in sufficient amount, which when added to any remaining proceeds from the Letter of Credit, will equal the full principal sum of the security deposit. Tenant shall have the right to provide a Letter of Credit in the face amount of One Hundred Thousand Dollars ($100,000.00), representing the $50,000.00 security deposit required above and the $50,000.00 deposit required under the Amended and Restated Office Lease of even date herewith between Landlord and Tenant for Building VIII. If Tenant elects to provide a Letter of Credit in the face amount of One Hundred Thousand Dollars, one-half of such Letter of Credit ($50,000.00) shall be applicable to the security deposit under this Lease, and one-half of the Letter of Credit ($50,000.00) will be applicable to the security deposit under the Amended and Restated Office Lease for Building VIII. If the security deposit is in the form of cash, Landlord shall be entitled to commingle the security deposit with its own funds, and Landlord shall not be required to pay Tenant any interest thereon. Tenant further agrees that no mortgagee or holder of a deed of trust on the Premises and no purchaser of said Premises at any foreclosure sale shall have any liability to Tenant for Tenant’s security deposit, unless such security deposits are actually delivered to such mortgagee, holder of a deed of trust or purchaser.

(d) As it relates to the provisions herein, every use of the term “Event of Default” or “default” shall be limited to that meaning of the terms set forth in Section 13 of this Lease.

35. Bankruptcy.

(a) An “Act of Bankruptcy” shall mean:

(i) the application by Tenant or any guarantor of Tenant or its or their consent to the appointment of a receiver, trustee or liquidator of Tenant or any guarantor of Tenant or a substantial part of its or their assets;

(ii) the filing of voluntary petition in bankruptcy or the admission in writing by Tenant or any guarantor of Tenant of its inability to pay its debts as they become due;

(iii) the making by Tenant or any guarantor of Tenant of an assignment for the benefit of its creditors;

(iv) the filing of a petition or an answer seeking a reorganization or an arrangement with its creditors or an attempt to take advantage of any insolvency law;

(v) the filing of an answer admitting the material allegations of a petition filed against Tenant or any guarantor of Tenant in any bankruptcy, reorganization or insolvency proceeding;

(vi) the entering of an order, judgment or decree by any court of competent jurisdiction adjudicating Tenant or any guarantor of Tenant a bankrupt or an insolvent, approving a petition seeking such a reorganization, or appointing a receiver, trustee or liquidator of Tenant or any guarantor of Tenant or of all or a substantial part of its or their assets; or

(vii) the commencing of any proceeding under any bankruptcy, reorganization, arrangement, insolvency, readjustment, receivership or similar law, and the continuation of such order, judgment, decree or proceeding unstayed for a period of sixty (60) days.

(b) Upon the occurrence of an Act of Bankruptcy, this Lease and all rights of Tenant hereunder shall automatically terminate with the same force and effect as if the date of any such event were the date stated herein for the expiration of the term, and Tenant shall vacate and surrender the Premises, but shall remain liable as herein provided. Landlord reserves any and all remedies provided herein or at law or in equity.

(c) If this Lease is not terminated in accordance with subsection (b) above because such termination is not permitted under the Bankruptcy Code, 11 U.S.C. 101 et seq. (the “Bankruptcy Code”), then upon the filing of a petition by or against Tenant under the Bankruptcy Code, Tenant, as debtor and as debtor in possession, and any trustee who may be appointed, agree:

(i) To perform each and every obligation of Tenant under this Lease until such time as this Lease is either rejected or assumed by order of the United States Bankruptcy Court;

(ii) To pay monthly in advance on the first day of each month as reasonable compensation for use and occupancy of the Premises an amount equal to all basic rent and all additional rent reserved hereunder;

(iii) To reject or assume this Lease within sixty (60) days of the filing of such petition under Chapter 7 of the Bankruptcy Code or within thirty (30) days of the filing of a petition under any other Chapter;

(iv) To give Landlord at least forty-five (45) days’ prior written notice of any proceeding relating to any assumption of this Lease;

(v) To give Landlord at least thirty (30) days’ prior written notice of any abandonment to be deemed conclusively a rejection of this Lease;

(vi) To be deemed conclusively to have rejected this Lease in the event of the failure to comply with any of the above; and

(vii) To be deemed to have consented to the entry of an order by an appropriate United States Bankruptcy Court providing all of the above, waiving notice and hearing of the entry of same.

(d) Not withstanding anything in this Lease to the contrary, all amounts payable by Tenant to or on behalf of Landlord hereunder, whether or not expressly denominated as rent, shall constitute “rent” for the purposes of Section 502(b)(7) of the Bankruptcy Code, including, without limitation, reasonable attorney’s fees incurred by Landlord by reason of Tenant’s bankruptcy.

(e) In the event that this Lease is assigned to any person or entity pursuant to the provisions of the Bankruptcy Code, any and all monies or other consideration payable or otherwise to be delivered in connection with such assignment shall be paid or delivered to Landlord, shall be and remain the exclusive property of Landlord, and shall not constitute property of Tenant or of the estate of Tenant within the meaning of the Bankruptcy Code. Any and all monies or other consideration constituting Landlord’s property under the preceding sentence not directly paid or delivered to Landlord shall be held in trust for the benefit of Landlord by the recipient thereof and be promptly paid to or turned over to Landlord. If Tenant assumes this Lease and proposes to assign the same pursuant to the provisions of the Bankruptcy Code to any person or entity who shall have made a bona fide offer to accept an assignment of this Lease on terms acceptable to Tenant, the notice of such proposed assignment setting forth (i) the name and address of such person; (ii) all of the terms and conditions of such offer; and (iii) adequate assurance to be provided to Landlord to assure such assignee’s future performance under the Lease, including, without limitation, the assurance referred to in Section 365(b)(3) of the Bankruptcy Code, or any such successor or substitute legislation or rule thereto, shall be given to Landlord by Tenant, but in any event no later than ten (10) days prior to the date that Tenant shall make application to a court of competent jurisdiction for authority and approval to enter into such assignment and assumption, and Landlord shall thereupon have the prior right and option, to be exercised by notice to Tenant given at any time prior to the effective date of such proposed assignment, to accept an assignment of this Lease upon the same terms and conditions and for the same consideration, if any, as the bona fide offer made by such person, less any brokerage commission which may be payable out of the consideration to be paid by such person for the assignment of this Lease. 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 deed to have assumed all of the obligations arising under this Lease on and after the date of such assignment. Any such assignee shall, upon demand, execute and deliver to Landlord an instrument confirming such assumption.

(f) Nothing contained in this Section 35 shall be deemed in any manner to limit Landlord’s rights and remedies under the Bankruptcy Code, as presently existing or as may hereafter be amended.

(g) No default under this Lease by Tenant, either prior to or subsequent to any Act of Bankruptcy, shall be deemed to have been waived unless expressly done so in writing by Landlord.

(h) Neither Tenant’s interest in this Lease, nor any estate created hereby in Tenant nor any interest herein or therein, shall pass to any trustee or receiver or assignee for the benefit of creditors or otherwise by operation of law except as may specifically be provided by the Bankruptcy Code.

36. Environmental Provisions.

(a) Tenant and its successors and assigns shall use and operate the Premises, the Building and the Property, respectively, at all times during the term hereof, under and in compliance with the laws of Loudoun County and the Commonwealth of Virginia, and in compliance with all applicable Environmental Legal Requirements. “Environmental Legal Requirements” shall mean any applicable law relating to public health, safety or the environment, including, without limitation, relating to releases, discharges or omissions to air, water, land or groundwater, to the withdrawal or use of groundwater, to the use and handling of polychlorinated biphenyls (“PCB’s”) or asbestos, or asbestos containing products or materials, to the disposal, treatment, storage or management of solid or other hazardous or harmful wastes or to exposure to toxic, hazardous or other harmful materials (collectively “Hazardous Substances”), to the handling, transportation, discharge or release of gaseous or liquid substance and any regulation or final order or directive issued pursuant to such statute or ordinance, in each case applicable to the Premises, the Building, the Property or their operation, construction or modification, including without limitation the following: the Clean Air Act, the Federal Water Pollution Control Act (“FWPCA”), the Safe Drinking Water Act, the Toxic Substances Control Act, the Comprehensive Environmental Response Compensation and Liability Act, as amended by the Solid and Hazardous Waste Amendments of 1984 (“RCRA” ), the Occupational Safety and Health Act, the Emergency Planning and Community Right-to-Know Act of 1986, the Solid Waste Disposal Act, and any state or local statutes addressing similar matters, and any state or local statute providing for financial responsibility for clean-up or other actions with respect to the release or threatened release of any of the above-referenced substances.

In the event any such condition develops and it is caused by Tenant, Tenant agrees to remedy such condition promptly at Tenant’s sole expense. Tenant hereby agrees to indemnify, defend and hold Landlord harmless from any such costs, expenses, actions or liabilities arising from mold within the Premises caused by Tenant, which indemnity shall include reasonable legal fees incurred by Landlord as the result thereof.

potential mold problem, regardless of what may have caused such problem.

(d) Tenant further agrees that, in the event Landlord notifies Tenant of Landlord’s intention to remediate mold in the Premises or in any adjoining property of Landlord, Tenant will provide access to the Premises to permit Landlord to remediate any such problem. In the event Landlord determines that Tenant should vacate the Premises during such remediation which was not caused by any act or omission of Tenant, its agents, employees, contractors or invitees, Tenant agrees to relocate, at Landlord’s expense, to another Premises owned by Landlord or an affiliate of Landlord, if necessary, in order for Landlord to complete such remediation.
