The Premises are located in the Building described in Section 1.b. hereof. The lease of the Premises to Tenant includes the non-exclusive right, together with other tenants of the Building and members of the public, to use the common public areas of the Building and the land on which the Building is situated (the “Land”), but includes no other rights not specifically set forth. The parties hereto acknowledge that the Building constitutes one of three (3) office buildings owned by Landlord or Landlord’s affiliates in the office project known as “Woodland Park,” the other buildings having a street address of 0000 Xxxxxxxxx Xxxx Xxxxx and 0000 Xxxxxxxxx Xxxx Xxxxx, Xxxxxxx, Xxxxxxxx (collectively, along with the Building, the “Buildings”). For all purposes hereunder, the Buildings, the land on which the Buildings are located (the “Project Land”) and all common areas, roadways and public areas therein or thereon are collectively referred to herein as the “Project.”

b. Improvements. Landlord shall deliver the Premises to Tenant in its “as-is” condition without (A) any obligation on Landlord’s part to undertake or, except for the Improvement Allowance (as defined in the Work Agreement (hereinafter defined)) to be provided by Landlord pursuant to the Work Agreement, pay for, any improvements or alterations therein; or (B) except as otherwise expressly set forth herein, any representations or warranties regarding the condition thereof. Tenant shall, at Tenant’s sole cost and expense, subject to the application of the Improvement Allowance, construct in the Premises the Tenant Improvements (as defined in the Work Agreement) described in the Work Agreement attached hereto as Exhibit B (the “Work Agreement”), in substantial accordance with the terms and conditions of the Work Agreement. In the event that Landlord and Tenant have not finally agreed upon the scope and details of the Tenant Improvements as of the Effective Date, Tenant’s submissions to Landlord of plans and specifications detailing such work shall be subject to Landlord’s written approval in accordance with the Work Agreement. The Tenant Improvements shall be subject to Landlord’s prior written approval, shall comply with all applicable building codes, laws and regulations (including, without limitation, the Americans with Disabilities Act, as amended (the “ADA”)), shall not require any changes to or modifications of any of the mechanical, electrical, plumbing or other systems of the Building, and shall otherwise be constructed in strict accordance with the terms of the Work Agreement. The cost of all design, architectural and engineering work, demolition costs, construction costs, construction supervision, contractors’ overhead and profit, licenses and permits, and all other costs and expenses incurred in connection with the Tenant Improvements shall be at Tenant’s sole cost and expense, subject to the application of the Improvement Allowance pursuant to the terms and conditions of the Work Agreement.

b. Tenant’s Pass-Through Costs.

(i) As used in this Lease:

(1) “Operating Expenses” shall mean any and all expenses, costs and disbursements (but not specific costs billed to and paid by specific tenants) of every kind and nature incurred by Landlord in connection with the ownership, management, operation, maintenance, servicing and repair of the Building and appurtenances thereto, including, without limitation, the common areas thereof, and the Land, including, but not limited to, employees’ wages, salaries, welfare and pension benefits and other fringe benefits; payroll taxes; telephone service; painting of common areas of the Building; exterminating service; detection and security services; concierge services; sewer rents and charges; premiums for fire and casualty, liability, rent, workmen’s compensation, sprinkler, water damage and other insurance; repairs and maintenance; building supplies; uniforms and dry cleaning; snow removal; the cost of obtaining and providing electricity, water and other public utilities to all areas of the Building; trash removal; janitorial and cleaning supplies; and janitorial and cleaning services; window cleaning; service contracts for the maintenance of elevators, boilers, HVAC and other mechanical, plumbing and electrical equipment; fees for all licenses and permits required for the ownership and operation of the Building; business license fees and taxes; the rental value of the management office maintained in the Building, if any; all costs of operating and maintaining equipment in the health and fitness facility located in the Building; sales, use and personal property taxes payable in connection with tangible personal property and services purchased for the management, operation, maintenance, repair, cleaning, safety and administration of the Buildings; legal fees; accounting fees relating to the determination of Operating Expenses and the tenants’ share thereof and the preparation of statements required by tenant’s leases; management fees, whether or not paid to any person having an interest in or under common ownership with Landlord; purchase and installation of indoor plants in the common areas; and landscaping maintenance and the purchase and replacement of landscaping services, plants and shrubbery. If Landlord makes an expenditure for a capital improvement to the Building (or any portion thereof) by installing energy conservation or labor-saving devices to reduce Operating Expenses, or to comply with any law, ordinance or regulation pertaining to the Building (each, a “Permitted Capital Expenditure”), and if, under generally accepted accounting principles, such expenditure is not a current expense, then the cost thereof shall be amortized over a period equal to the useful life of such improvement, determined in accordance with generally accepted accounting principles, and the amortized costs allocated to each calendar year during the Term, together with an imputed interest amount calculated on the unamortized portion thereof using an interest rate of twelve percent (12%) per annum,

shall be treated as an Operating Expense. In the event that any costs with respect to the operation and management of more than one of the Buildings are allocated among the Building and any other building owned by Landlord, the costs so allocated to the Building shall be included in the calculation of Operating Expenses. Notwithstanding anything to the contrary contained in this Section 4.b(i)(1), Operating Expenses shall not include (i) costs of capital improvements or capital expenditures determined under generally accepted accounting principles, except for Permitted Capital Expenditures; (ii) interest, principal, late charges, prepayment penalties or premiums on any debt owed by Landlord (including any mortgage debt) and depreciation; (iii) expenses resulting from the negligence or willful misconduct of Landlord, its agents or employees, but only if such expenses would not have been incurred but for such negligence or willful misconduct; (iv) legal fees, space planners’ fees, real estate brokers’ leasing commissions and advertising expenses incurred in connection with the leasing of space in the Building; (v) costs for which Landlord is reimbursed by insurance (by Landlord’s carrier, Tenant’s carrier or by any third party’s insurance carrier) or pursuant to any warranty; (vi) any bad debt loss, rent loss, or reserves for replacements; (vii) costs associated with the operation of the limited liability company which constitutes Landlord, as opposed to costs associated with the operation of the Building; (viii) costs of selling, syndicating, financing, mortgaging or hypothecating any of Landlord’s interest in the Building; (ix) litigation costs relating to suits filed by or against Landlord and/or the Building (expressly excluding tax assessment appeals); (x) fines and penalties; (xi) amounts paid as ground rent by Landlord; (xii) the portion of any costs paid to affiliates of Landlord for services at the Building to the extent that such costs exceed the cost of such services if rendered by unaffiliated third parties on an arms-length basis; (xiii) rentals and other related expenses incurred in leasing air conditioning systems, elevators or other equipment ordinarily considered to be of a capital nature if purchased (excluding equipment not affixed to the Building which is used in providing janitorial or similar services); (xiv) the cost of all items and services with respect to which Landlord receives reimbursement (excluding reimbursement by way of Tenant’s Pass-Through Costs paid by Tenant or other tenants); (xv) costs incurred by Landlord due to the violation by Landlord of the terms and conditions of any space lease in the Building, provided that such costs would not have been incurred by Landlord but for such violation; (xvi) attorneys’ fees, costs and expenses incurred by Landlord in connection with disputes with tenants or prospective tenants of the Building; (xvii) costs incurred in connection with the sale, financing, refinancing, mortgaging or sale of the Building, including brokerage commissions, attorneys’ and accountants’ fees, closing costs, title insurance premiums, transfer taxes and interest charges; (xviii) costs of correcting any violations of law applicable to the Building, which violations existed on the Effective Date; (xix) Landlord’s political or charitable contributions; (xx) Real Estate Taxes; (xxi) costs incurred in connection with work or services or other benefits that are not offered to Tenant but that are provided to another tenant or occupant of the Building without additional cost; (xxii) federal income taxes assessed against Landlord; (xxiii) costs of remediating Hazardous Materials (hereinafter defined) in the Building to the extent such Hazardous Materials (A) were present in the Building on the Commencement Date in violation of any Environmental Laws (hereinafter defined) or (B) were introduced to the Building by Landlord, or its agents or employees; or (xxiv) the costs of constructing any health and fitness facility located in the Building and the cost of purchasing, installing or replacing any equipment in such health and fitness facility. Landlord shall not duplicate any component of Operating Expenses under the terms of this Lease.

(2) “Real Estate Taxes” shall mean all taxes, assessments and charges levied upon or with respect to the Land (or any portion thereof), the Building, and any improvements adjacent thereto (computed as payable in installments as permitted by law regardless of whether so paid), including, without limitation, vault rents, if any, franchise taxes, any tax, fee or excise on rents, on the square footage of the Premises including the Fairfax County Business License Tax, on the act of entering into this Lease, on the occupancy of Tenant, on account of the rent hereunder or the business of renting space now or hereafter levied or assessed against Landlord by the United States of America or the state, county, city or town in which the Building are located, or any political subdivision, public corporation, district or other political or public entity; and shall also include any other tax to the extent that such tax is imposed in lieu of or in addition to such Real Estate Taxes. Reasonable legal fees, costs and disbursements incurred by Landlord in connection with any proceedings for appeal or reduction of any Real Estate Taxes shall also be considered Real Estate Taxes for the year in question. In the event that Real Estate Taxes for the Land and the Building are not separately assessed, Landlord shall allocate to the Land and the Building the portion of the total Real Estate Tax assessment that fairly represents the relative values of all properties that have been assessed together.

(3) “Tenant’s Pro Rata Share (Operating Expenses),” as of the date hereof, shall be as provided in Section 1.g., representing the ratio that the rentable area of the Premises bears to the total rentable area of office space in the Building. If either the rentable area of the Premises or the total rentable area of the Building, shall be increased or decreased, as reasonably determined by Landlord, Tenant’s Pro Rata Share (Operating Expenses) shall be adjusted accordingly.

(4) “Tenant’s Pro Rata Share (Real Estate Taxes),” as of the date hereof, shall be as provided in Section 1.g., representing the ratio that the rentable area of the Premises bears to the total rentable area of the Building. If either the rentable area of the, Premises or the total rentable area of the Building, shall be increased or decreased, as reasonably determined by Landlord, Tenant’s Pro Rata Share (Real Estate Taxes) shall be adjusted accordingly.

(5) “Base Year” means calendar year 2006.

(ii) If, in any calendar year during the Term, the total amount of Operating Expenses for the Buildings exceed the amount of Operating Expenses in the Base Year, then Tenant shall pay to Landlord, as Additional Rent, commencing on January 1, 2007, an amount which is the product of (1) the amount of such increase in Operating Expenses, multiplied by (2) Tenant’s Pro Rata Share (Operating

Expenses). Tenant’s Pro Rata Share (Operating Expenses) of increases in Operating Expenses for any partial calendar year during the Term shall be determined by multiplying the amount of Tenant’s Pro Rata Share (Operating Expenses) of increases in Operating Expenses for the full calendar year by a fraction, the numerator of which is the number of days during such calendar year falling within the Term and the denominator of which is three hundred sixty-five (365). If in any calendar year during the Term, the amount of Real Estate Taxes exceeds the amount of Real Estate Taxes for the Base Year, then Tenant shall pay, as Additional Rent, commencing on January 1, 2007, an amount which is the product of (x) the amount of such increase in Real Estate Taxes, multiplied by (y) Tenant’s Pro Rata Share (Real Estate Taxes). Tenant’s Pro Rata Share (Real Estate Taxes) of increases in Real Estate Taxes for any partial calendar year during the Term shall be determined by multiplying the amount of Tenant’s Pro Rata Share (Real Estate Taxes) of increases in Real Estate Taxes for the full calendar year by a fraction, the numerator of which is the number of days during such calendar year falling within the Term and the denominator of which is three hundred sixty-five (365).

(iii) If at any time during the Base Year, or during any subsequent calendar year (“Subsequent Year”), less than ninety-five percent (95%) of the total rentable square feet of office space in the Building is occupied by tenants, the amount of Operating Expenses for the Base Year, or for any such Subsequent Year, as the case may be, shall be deemed to be the amount of Operating Expenses as reasonably estimated by Landlord that would have been incurred if the percentage of occupancy of the Building during the Base Year or any such Subsequent Year was ninety-five percent (95%). If at any time during any calendar year, any part of the Building is leased to a tenant (hereinafter referred to as a “Special Tenant”) who, in accordance with the terms of its lease, provides its own utilities, cleaning or janitorial services or other services or is not otherwise required to pay a share of Operating Expenses in accordance with the methodology set forth in this Section 4.b., and Landlord does not incur the cost of such services, Operating Expenses for such calendar year shall be increased by the additional costs for cleaning and janitorial services and such other applicable expenses as reasonably estimated by Landlord that would have been incurred by Landlord if Landlord had furnished and paid for cleaning and janitorial services and such other services for the space occupied by the Special Tenant, or if Landlord had included such costs in “operating expenses” as defined in the Special Tenant’s lease.

(iv) During the month of December, 2006 (or as soon thereafter as is reasonably practicable), and thereafter during the month of December of each Lease Year (or as soon thereafter as is reasonably practicable), Landlord shall use reasonable efforts to furnish to Tenant a statement of Landlord’s estimate of Tenant’s Pass-Through Costs for the next calendar year. “Tenant’s Pass-Through Costs” shall be an amount equal to the sum of (1) Tenant’s Pro Rata Share (Operating Expenses) multiplied by the difference between Operating Expenses incurred during any calendar year during the Term, and Operating Expenses incurred in the Base Year; plus (2) Tenant’s Pro Rata Share (Real Estate Taxes) multiplied by the difference between Real Estate Taxes for any calendar year during the Term and Real Estate Taxes incurred during the Base Year. Such statement shall show the amount of Tenant’s Pass-Through Costs, if any, payable by Tenant for such calendar year pursuant to this Section 4.b. on the basis of Landlord’s estimate. Commencing on January 1, 2007, and continuing on each monthly rent payment date thereafter until further adjustment pursuant to this Section 4.b.(iv), Tenant shall pay to Landlord one-twelfth (1/12) of the amount of said estimated Tenant’s Pass-Through Costs. Within one hundred and twenty (120) days after the expiration of each calendar year during the Term, Landlord shall furnish to Tenant a statement (the “Expense Statement”) showing the actual Operating Expenses and Real Estate Taxes for such calendar year. The Expense Statement shall be conclusive and binding on Tenant, unless objected to in writing by Tenant within sixty (60) days following Tenant’s receipt thereof. In case of an underpayment, Tenant shall, within thirty (30) days after the receipt of such statement, pay to Landlord an amount equal to such underpayment. In case of an overpayment, Landlord shall credit the next monthly rental payment by Tenant with an amount equal to such overpayment. Additionally, if this Lease shall have expired, Landlord shall apply such excess against any sums due from Tenant to Landlord and shall refund any remainder to Tenant within sixty (60) days after the expiration of the calendar year in which the Term ends.

(v) Tenant shall be entitled to the following audit right with respect to a Expense Statement delivered by Landlord. Such audit right shall be exercisable by Tenant’s providing Landlord with written notice of Tenant’s exercise of such audit right within sixty (60) days of Tenant’s receipt of such Expense Statement, time being of the essence. Tenant’s notice shall contain a statement of Tenant’s reasonable objections to such Expense Statement. If, within forty-five (45) days after Landlord’s receipt of Tenant’s written notice, Landlord and Tenant are unable to resolve Tenant’s objections, then not later than fifteen (15) days after the expiration of such forty-five (45)-day period Tenant shall deliver to Landlord written notice (the “Audit Notice”) that it wishes to employ on an hourly rate (and not a contingency fee) basis an independent certified public accounting firm reasonably acceptable to Landlord to inspect and audit Landlord’s books and records at the Building relating to the objections raised in Tenant’s notice. If Tenant elects to employ such accounting firm as set forth above, then Tenant shall deliver to Landlord a confidentiality and nondisclosure agreement satisfactory to Landlord executed by Tenant and such accounting firm, and provide Landlord not less than fifteen (15) days’ notice of the date on which the accounting firm desires to examine Landlord’s books and records at the Building during regular business hours; provided, however, that such date shall be between thirty (30) and ninety (90) days after Tenant delivers to Landlord the Audit Notice. Such audit shall be limited to a determination of whether Landlord calculated the Expense Statement in accordance with the terms and conditions of this Lease. Except as otherwise expressly set forth below, all costs and expenses of any such audit shall be paid by Tenant. Notwithstanding anything contained herein to the contrary, Tenant shall be entitled to exercise its right to audit pursuant to this Section 4.b(v) only in strict accordance with the foregoing procedures and each such audit shall relate only to the calendar year covered by the Expense Statement most recently delivered by Landlord. As a condition precedent to exercising its audit rights, Tenant shall

pay to Landlord all monies which Landlord claims are owing by Tenant, as shown on the Expense Statement. Except for an Affiliate (hereinafter defined) of Tenant to which Tenant has assigned its interest in this Lease, the audit rights pursuant to this Section 4b(v) shall not transfer or apply to any subtenant or any other person or entity other than K12 Inc. If on account of any demonstrated errors in the Expense Statement under audit, Tenant is entitled to a refund of the amount paid by Tenant for Tenant’s Pass-Through Costs for the calendar year under audit because such Expense Statement overstated the amounts to which Landlord was entitled hereunder, Landlord shall credit the next monthly rental payment by Tenant with an amount equal to such refund. If the Expense Statement under audit overstated the amounts to which Landlord was entitled to hereunder by more than four percent (4%), then Landlord shall promptly reimburse Tenant for its reasonable costs and expenses incurred in such audit in an amount not to exceed Two Thousand Five Hundred Dollars ($2,500.00). In the event the audit reveals an underpayment by Tenant for Tenant’s Pass-Through Costs, Tenant shall pay to Landlord an amount equal to such underpayment within thirty (30) days.

(vi) All monies received from Tenant as Tenant’s Pass-Through Costs shall be received by Landlord to pay Operating Expenses and Real Estate Taxes of the Building and the Land. Notwithstanding the foregoing, Landlord shall have the right to commingle Tenant’s Pass-Through Costs with other funds collected by Landlord.

(vii) Tenant’s obligation to pay Tenant’s Pass-Through Costs pursuant to the provisions of this Section 4.c. shall survive the expiration or other termination of this Lease with respect to any period during the Term hereof and with respect to any holdover period of occupancy following the expiration of the Term.

(viii) Notwithstanding anything contained in this Section 4.b. to the contrary, Landlord reserves the right, at any time in the future, to aggregate some or all of the Operating Expenses and/or Real Estate Taxes with the expenses and/or taxes, respectively, incurred in connection with the operation of all the Buildings in the Project, in which event Tenant’s Pro Rata Share (Operating Expenses) and/or Tenant’s Pro Rate Share (Real Estate Taxes), as applicable, shall be adjusted accordingly by Landlord.

c. Payment of Rent. All Rent shall be paid in lawful money of the United States of America without deduction, diminution, set-off, counterclaim or prior notice or demand, at the office of Landlord as provided in Section 1.i. hereof or at such other place as Landlord may hereafter designate in writing, on the first day of every calendar month during the Term. All such payments shall be made by good checks payable to Landlord or such other person, firm or corporation as Landlord may hereafter designate in writing. No payment by Tenant or receipt and acceptance by Landlord of a lesser amount than the Monthly Base Rent or Additional Rent shall be deemed to be other than partial payment of the full amount then due and payable; nor shall any endorsement or statement on any check or any letter accompanying any check, payment of Rent or other payment, be deemed an accord and satisfaction; and Landlord may accept, but is not obligated to accept, such partial, payment without prejudice to the Landlord’s right to recover the balance due and payable or to pursue any other remedy provided in this Lease or by law. If Landlord shall at any time or times accept Rent after it becomes due and payable, such acceptance shall not excuse a subsequent delay or constitute a waiver of Landlord’s rights hereunder. Any Rent owed by Tenant to Landlord, including, without limitation, Annual Base Rent, Additional Rent, Tenant’s Pass-Through Costs and Late Charges, which is not paid within five (5) days after the date such payment is due shall bear interest from the due date at a rate equal to the prime rate on corporate loans quoted in the Wall Street Journal (the “Prime Rate”) plus two percent (2%). In addition, if any amount of Rent required to be paid by Tenant to Landlord under the terms of this Lease is not paid within five (5) days after the date such payment is due, then in addition to paying the amount of Rent then due, Tenant shall pay to Landlord a late charge (the “Late Charge”) equal to four percent (4%) of the amount of Rent then required to be paid; provided, however, that Landlord agrees to waive the first (1^st) such Late Charge in any Lease Year during the Term, provided that Tenant pays the Rent then due within three (3) days after Tenant’s receipt of written notice from Landlord. Payment of such Late Charge will not excuse the untimely payment of Rent. In the event Tenant makes any payment of Rent by check and said check is returned by the bank unpaid, Tenant shall pay to Landlord the sum of Seventy-Five Dollars ($75.00) to cover the costs and expenses of processing the returned check, in addition to the Rent payment and any other charges provided for herein. Any interest, Late Charge and other amounts charged hereunder shall constitute Additional Rent.

d. Separate Metering and Rent Reduction. Landlord may elect to discontinue the distribution or furnishing of electricity and/or water to the Premises if such services are available and may feasibly be furnished directly to Tenant by the utility company supplying same. In the event of any such election by Landlord: (i) Landlord agrees to give reasonable advance notice of such discontinuance to Tenant; (ii) Landlord agrees to permit Tenant to receive electricity and/or water directly from the utilities supplying such service to the Building and to permit the existing feeders, risers, wiring, pipes and other facilities serving the Premises to be used by Tenant for such purpose to the extent they are suitable and safely capable of carrying Tenant’s requirements; (iii) Landlord agrees to pay such charges and costs, if any, as such public utility may impose in connection with the installation of Tenant’s meters; (iv) Landlord shall install, at Landlord’s expense, any additional equipment reasonably required by the utility company which may be necessary to furnish such service to Tenant; and (v) the amount of Additional Rent payable in respect to the Operating Expenses shall be decreased appropriately to reflect such discontinuance. This Lease shall remain in full force and effect and such discontinuance shall not constitute an actual or constructive eviction, in whole or in part, or relieve Tenant from any of its obligations under this Lease.

5. SECURITY DEPOSIT.

a. Landlord acknowledges receipt from Tenant of the Letter of Credit (hereinafter defined) in the amount set forth in Section 5.b, below to be held by Landlord during the Term as collateral security (the “Security Deposit”) (and not prepaid rent), for the payment of Annual Base Rent and Additional Rent and for the faithful performance by Tenant of all other covenants, conditions and agreements of this Lease. Landlord shall not be obligated to hold the Letter of Credit or any proceeds thereof in a separate account. The Security Deposit shall not earn interest. If any sum payable by Tenant to Landlord shall be overdue and unpaid, or if Landlord makes any payments on behalf of Tenant, or if Tenant fails to perform any of the terms of this Lease, then Landlord, at its option and without prejudice to any other remedy which Landlord may have, may apply all or part of the Security Deposit to compensate Landlord for the payment of Annual Base Rent or Additional Rent, or any loss or damage sustained by Landlord. Tenant shall restore the Security Deposit to the original sum deposited upon demand. Provided that Tenant shall have made all payments and performed all covenants and agreements of this Lease, Landlord shall return the Security Deposit to Tenant (except to the extent of any portion of the Security Deposit which has been applied by Landlord and not restored by Tenant) within ninety (90) days after the expiration of this Lease or the vacation of the Premises by Tenant.

b. Contemporaneously with Tenant’s execution and delivery to Landlord of this Lease, Tenant has delivered to Landlord an unconditional and irrevocable letter of credit issued by a federally-insured banking institution reasonably acceptable to Landlord in the face amount of Two Million One Hundred Thirty-Six Thousand Five Hundred Thirty-Five and 98/100 Dollars ($2,136,535.98) (the “Letter of Credit”), as a Security Deposit to be held by Landlord until disposed of in accordance with the provisions of this Section 5. The Letter of Credit shall be in the form attached hereto as Exhibit E, and shall be issued for a term ending ninety (90) days after the Lease Expiration Date (or, if applicable, the last day of any applicable Extension Period (hereinafter defined)). If the Letter of Credit (or any replacement thereof) is issued for an effective period of time ending less than ninety (90) days after the expiration of the Term of this Lease (or any renewal thereof), Tenant shall from time to time, and not later than sixty (60) days prior to the expiration of the Letter of Credit, replace each such expiring Letter of Credit with a new Letter of Credit in the same amount and upon the same terms. The Letter of Credit (and any replacement thereof) may be drawn upon by Landlord under the terms and conditions as provided in this Section 5. Failure of Tenant to renew the Letter of Credit at least sixty (60) days prior to its expiration shall constitute an Event of Default (hereinafter defined) under this Lease and shall entitle Landlord, in addition to the other remedies contained in this Lease, to draw upon the Letter of Credit.

c. Landlord (or the beneficiary under the Letter of Credit, if such beneficiary is not Landlord) shall have the right to draw upon the Letter of Credit in any of the following circumstances (in addition to any other right to draw on the Letter of Credit that is set forth in this Section 5): (i) if the credit rating of the issuer of the Letter of Credit is downgraded from the credit rating of such issuer at the time of the issuance of the Letter of Credit, the issuer of the Letter of Credit shall enter into any supervisory agreement with any governmental authority, or the issuer of the Letter of Credit shall fail to meet any capital requirements imposed by applicable law, and Tenant fails to deliver to Landlord (or the beneficiary under the Letter of Credit, if such beneficiary is not Landlord) a replacement Letter of Credit complying with the terms of this Lease within thirty (30) days of request from Landlord, (ii) if Tenant fails to provide Landlord with any renewal or replacement Letter of Credit complying with the terms of this Lease at least sixty (60) days prior to expiration of the then-current Letter of Credit where the issuer of such Letter of Credit has advised Landlord of its intention not to renew the Letter of Credit, (iii) if Tenant fails to provide Landlord with any renewal or replacement Letter of Credit complying with the terms of this Lease at least sixty (60) days prior to the final expiration date (i.e., the date that, by the terms of the Letter of Credit, the Letter of Credit expires and is either not subject to any automatic renewal or extension or the conditions to such automatic renewal or extension have not then been satisfied) of the then-current Letter of Credit if such Letter of Credit expires prior to the date that is ninety (90) days after the end of the Term, or (iv) any voluntary or involuntary proceedings are filed by or against Tenant under any bankruptcy, insolvency or similar laws. In the event the Letter of Credit is drawn upon due solely to the circumstances described in the foregoing clauses (i), (ii), (iii) or (iv), the amount drawn shall be held by Landlord as a cash Security Deposit in accordance with the terms of this Section 5, and shall be otherwise retained, expended or disbursed by Landlord for any amounts or sums due under this Lease to which the proceeds of the Letter of Credit could have been applied pursuant to this Lease, and Tenant shall be liable to Landlord for restoration, by way of a Letter of Credit complying with the terms of this Lease or, at Landlord’s sole option, cash, of any amount so expended to the same extent as set forth in this Section 5.

d. In the event of the sale or transfer of Landlord’s interest in the Building, Landlord shall transfer the Letter of Credit to the purchaser or assignee, in which event Tenant shall look only to the new landlord for the return of the Letter of Credit, and Landlord shall thereupon be released from all liability to Tenant for the return of the Security Deposit. Tenant hereby agrees not to look to the mortgagee, as mortgagee, mortgagee in possession, or successor in title to the property, for accountability for any security deposit required by the Landlord hereunder, unless said sums have actually been received by said mortgagee as security for Tenant’s performance of this Lease. In the event of any permitted assignment of Tenant’s interest in this Lease, the Letter of Credit may, at Landlord’s sole option, be held by Landlord as a deposit made by the assignee, and Landlord shall have no further liability to Tenant with respect to the return of the Letter of Credit.

e. Notwithstanding anything to the contrary contained in this Section 5, and provided that, as of the applicable Reduction Date (hereinafter defined): (a) Tenant is not in default of its obligations under the Lease, and (b) Landlord determines in its sole discretion that (i) Tenant’s Net Worth (hereinafter defined) equals or exceeds Twenty-Five Million Dollars ($25,000,000.00), (ii) Tenant’s Net Worth has increased during the immediately-preceding twelve (12) month period, (iii) Tenant’s ratio of current assets (minus good will and other intangibles) to current liabilities ‘(i.e., current assets divided by current

liabilities) is no less than 1.0, and (iv) Tenant’s ratio of total debt to total equity (i.e., total debt divided by total equity) as of the Reduction Date is not greater than 1.5, then the then-current face amount of the Letter of Credit shall be reduced by twenty—five percent (25%) as of the first day of each of the fourth (4^th), fifth (5^th) and sixth (6^th) Lease Years (each, a “Reduction Date”). In no event shall the face amount of the Letter of Credit be reduced below Five Hundred Thirty-Four Thousand One Hundred Thirty-Four Dollars ($534,134.00) pursuant to the terms of this Section 5.e). No such reduction in the face amount of the Letter of Credit shall be undertaken by the Tenant or the issuer of the Letter of Credit unless and until Landlord notifies such issuer in writing that Tenant has satisfied the conditions precedent to such reduction (“Landlord’s Reduction Notification”). The foregoing reductions shall be effected by Tenant replacing the Letter of Credit then being held by Landlord with a new Letter of Credit (complying with the terms of this Lease) in the amount then required to be maintained with Landlord pursuant to the foregoing provisions (or amending the then existing Letter of Credit to the amount then required to be maintained with Landlord pursuant to the foregoing provisions). At least thirty (30) days prior to the then-applicable Reduction Date, Tenant shall submit audited financial statements to Landlord containing financial information which Landlord confirms is sufficient to enable Landlord to determine whether Tenant has satisfied the conditions precedent set forth in subparagraph (b), above (the “Security Deposit Reduction Financial Statements”). The Security Deposit Reduction Financial Statements provided must be as of a date not more than six (6) months prior to the applicable Reduction Date. As used herein, the term “Net Worth” shall mean an amount equal to Tenant’s assets (excluding good will and other intangibles) as of the applicable Reduction Date minus Tenant’s liabilities as of the applicable Reduction Date. Provided Tenant has timely submitted the applicable Security Deposit Reduction Financial Statements to Landlord in accordance with the terms of this Section 5.e, Landlord shall use reasonable efforts to deliver the Landlord’s Reduction Notification to the issuer of the Letter of Credit within sixty (60) days after the applicable reduction date.

6. USE.

a. Tenant covenants with the Landlord not to use the Premises for any purpose other than general office use for the conduct of the Tenant’s business. Tenant shall not use the Premises or allow the Premises to be used (i) for any other purpose without the prior written consent of the Landlord; or (ii) in any manner or for any purpose which violates any applicable Legal Requirements (hereinafter defined). Except as otherwise set forth immediately below or in Section 9.f, below, Tenant, at Tenant’s expense, shall comply with all laws, codes, rules, orders, ordinances, directions, regulation, and requirements of federal, state, county, and municipal authorities, now in force or which may hereafter be in force, which shall impose any duty upon Landlord or Tenant with respect to the condition, maintenance, use, occupation, operation or alteration of the Premises, or the conduct of Tenant’s business therein, including, without limitation, the ADA and all applicable zoning, recycling and environmental laws and regulations. Tenant hereby agrees to indemnify and hold harmless Landlord and its agents, officers, directors and employees from and against any cost, damage, claim, liability and expense (including attorneys’ fees) arising out of claims or suits brought by third parties (including governmental authorities) against Landlord, its agents, officers, directors and employees alleging or relating to the failure of the Premises to comply with the terms of the ADA or any other law or regulation applicable to the Premises and/or its occupancy by Tenant. Notwithstanding the foregoing, the indemnity set forth in the immediately preceding sentence shall not apply to claims or suits arising out of the failure by the Sole Occupant Bathrooms (hereinafter defined) to comply with the terms of the ADA. As used herein, the term “Sole Occupant Bathrooms” means the bathrooms located in those portions of the Premises which are located on floors of the Building on which Tenant occupies one hundred percent (100%) of the rentable square footage of space on such floor. Tenant shall not use or permit the Premises or any part thereof to be used in any manner that constitutes waste, nuisance or unreasonable disturbances to other tenants of the Building or for any disorderly, unlawful or hazardous purpose and will not store or maintain therein any hazardous, toxic or highly combustible items other than usual and customary office supplies intended for Tenant’s use and in such event, only in such amounts as permitted by applicable law. Tenant covenants not to change Tenant’s use of the Premises without the prior written approval of Landlord.

b. Tenant shall not put the Premises to any use, the effect of which use is reasonably likely to cause cancellation of any insurance covering the Premises or the Building, or an increase in the premium rates for such insurance. In the event that Tenant performs or commits any act, the effect of which is to raise the premium rates for such insurance, Tenant shall pay Landlord the amount of the additional premium, as Additional Rent payable by Tenant upon demand therefor by Landlord. The Premises shall not be used for any illegal purpose or in violation of any regulation of any governmental body or the regulations or directives of Landlord’s insurance carriers, or in any manner which interferes with the quiet enjoyment of any other tenant of the Building. Tenant will not install or operate in the Premises any electrical or other equipment, other than such equipment as is commonly used in modern offices (specifically excluding mainframe computers), without first obtaining the prior written consent of Landlord, who may condition such consent upon the payment by Tenant of Additional Rent in compensation for excess consumption of water, electricity and/or other utilities, excess wiring and other similar requirements, and any changes, replacements or additions to any base building system, as may be occasioned by the operation of said equipment or machinery.

c. Tenant agrees to maintain the Premises, and the Tenant Improvements and other Alterations (hereinafter defined) therein, in good order, repair and condition during the Term at Tenant’s sole cost and expense, and Tenant will, at the expiration or other termination of the Term, surrender and deliver the same and all keys, locks and other fixtures connected therewith (excepting only Tenant’s personal property) in good order, repair and condition, as the same shall be at the Commencement Date, except as repaired, rebuilt, restored, altered or added to pursuant to this Lease, and except for ordinary wear and tear. Landlord shall have no obligation to Tenant to make any repairs in or to the Premises, the

Tenant Improvements or any Alterations, except as otherwise expressly set forth herein. Any and all damage or injury to the Premises (including, but not limited to, the Tenant Improvements), the Building or the Land caused by Tenant, or by any employee, agent, contractor, assignee, subtenant, invitee or customer of Tenant shall be promptly reported to Landlord and repaired by Tenant at Tenant’s sole cost; provided, however, that Landlord shall have the option of repairing any such damage, in which case Tenant shall reimburse Landlord for all actual costs incurred by Landlord in respect thereof as Additional Rent within twenty (20) days after Tenant receives Landlord’s notice of such costs.

d. Tenant shall not place a load upon the floor of the Premises exceeding the designated floor load capacity of the Building (e.g. 100 pounds per square foot: 80 pounds per square foot, live load, and 20 pounds per square foot, dead load) without Landlord’s prior written consent. Business machines, mechanical equipment and materials belonging to Tenant which cause vibration, noise, cold, heat or fumes that may be transmitted to the Building or to any other leased space therein to such a degree as to be objectionable to Landlord or to any other tenant in the Building shall be placed, maintained, isolated, stored and/or vented by Tenant at its sole expense so as to absorb and prevent such vibration, noise, cold, heat or fumes.

7. ASSIGNMENT AND SUBLETTING.

a. Tenant shall not, without the prior written consent of Landlord in each instance: (i) assign or otherwise transfer this Lease or any of Tenant’s rights hereunder, (ii) sublet the Premises or any part thereof, or permit the use of the Premises or any part thereof by any persons other than Tenant or its employees, agent and invitees, or (iii) permit the assignment or other transfer of this Lease or any of Tenant’s rights hereunder by operation of law. Landlord’s consent to a proposed assignment or sublease shall not be unreasonably withheld, conditioned or delayed, provided Landlord reasonably determines that the proposed assignee or subtenant (A) is of a type and quality consistent with the first-class nature of the Building, (B) has the financial capacity and creditworthiness to undertake and perform the obligations of this Lease or the sublease, (C) is not a party by whom any suit or action could be defended on the ground of sovereign immunity or diplomatic immunity and (D) will not impose any additional material burden upon Landlord in the operation of the Building (to an extent greater than the burden to which Landlord would have been had Tenant continued to use such part of the Premises). In addition, the following conditions must be satisfied at the time Tenant requests Landlord’s consent to an assignment or sublease:

(1) no Event of Default (hereinafter defined) exists and no event has occurred which, with notice and/or the passage of time, would constitute an Event of Default if not cured within the time, including any applicable grace period, specified herein;

(2) Landlord receives at least thirty (30) days prior written notice of Tenant’s intention to assign this Lease or sublet any portion of the Premises (“Tenant’s Transfer Notice”);

(3) the proposed use of the Premises will not violate any agreement affecting the Premises or the Building (provided, that if such proposed use will violate any such agreement, Landlord shall notify Tenant thereof after Landlord’s receipt of Tenant’s Transfer Notice);

(4) Tenant submits to Landlord, within five (5) days after Landlord’s request therefor, whatever information Landlord reasonably requires in order to permit Landlord to approve of or disapprove of the proposed subletting or assignment, including without limitation the name, business experience, financial history, net worth and business references of the proposed assignee or subtenant (and each of its principals), an in-depth description of the transaction, and the consideration delivered to Tenant for the assignment or sublease; and

(5) Tenant has paid to Landlord an administrative fee in the amount of Seven Hundred Fifty Dollars ($750.00) which shall be retained by Landlord whether or not such consent is granted.

b. All proposed subleases and assignments shall be on a form of sublease or assignment, whichever is applicable, reasonably acceptable to Landlord; and shall contain, inter alia, the following provisions: (i) any such assignment or sublease shall include an assumption by the assignee or subtenant, from and after the effective date of such assignment or sublease, of the performance and observance of the covenants and conditions to be performed and observed on the part of Tenant as contained in this Lease, and (ii) any such sublease or assignment shall specify that this Lease or sublease shall not be further assigned nor the Premises further sublet (except in strict accordance with the terms and conditions of this Lease) and shall specify that the term of such sublease shall not extend beyond one (1) day prior to the expiration of this Lease. The consent by Landlord to any assignment, transfer or subletting to any person or entity shall not be construed as a waiver or release of Tenant from any provision of this Lease, unless expressly agreed to in writing by Landlord (it being understood that Tenant shall remain primarily liable as a principal and not as a guarantor or surety), nor shall the collection or acceptance of rent from any such assignee, transferee, subtenant or occupant constitute a waiver or release of Tenant from any such provision. No consent by Landlord to any such assignment, transfer or subletting in any one instance shall constitute a waiver of the necessity for such consent in a subsequent instance.

c. In the event that Tenant assigns this Lease or sublets all or any portion of the Premises, Tenant shall pay to Landlord, as Additional Rent, fifty percent (50%) of the difference between (i) all sums

paid to Tenant or its agent by or on behalf of such assignee or subtenant under the assignment or sublease after deducting Tenant’s reasonable, actual expenses of obtaining such assignment or subleasing, including, but not limited to, brokerage commissions, tenant improvement or other allowances or concessions granted and actually paid out by Tenant, advertising and marketing costs incurred, and legal fees (with all such expenses amortized on a straight-line basis over the term of the proposed sublease or over the term of the assignment), and (ii) the Annual Base Rent and Additional Rent paid by Tenant under this Lease and attributable to the portion of the Premises assigned or sublet.

d. For purposes of this Section 7, a transfer, conveyance, grant or pledge, directly or indirectly, in one or more transactions, of an interest in Tenant (whether stock, partnership interest or other form of ownership or control, or the issuance of new interests) by which an aggregate of more than fifty percent (50%) of the beneficial interest in Tenant shall be vested in a party or parties who are not holders of such interest(s) as of the date hereof) shall be deemed an assignment of this Lease; provided, however, that this limitation shall not apply to any corporation, all of the outstanding voting stock of which is listed on a national securities exchange as defined in the Securities Exchange Act of 1934. The merger or consolidation of Tenant into or with any other entity, the sale of all or substantially all of Tenant’s assets, or the dissolution of Tenant shall each be deemed to be an assignment within the meaning of this Section.

e. Any assignment or subletting not in conformance with the terms of this Lease shall be void ab initio and shall, subject to the provisions of Section 16, constitute a default under the Lease.

f. Except in connection with an assignment of this Lease or a subletting of all or any portion of the Premises to an Affiliate of Tenant, upon receipt of Tenant’s Transfer Notice, Landlord may, at its option, in lieu of approving or rejecting the proposed assignment or subletting, exercise all or any of the following rights by written notice to Tenant of Landlord’s intent to do so within fifteen (15) business days of Landlord’s receipt of Tenant’s Transfer Notice:

(i) with respect to a proposed assignment of this Lease, the right to terminate this Lease on the effective date of proposed assignment as though it were the Lease Expiration Date;

(ii) with respect to a proposed sublease of the entire Premises for a sublease term ending during the last Lease Year of the Term, the right to terminate this Lease on the effective date of the sublease as though it were the Lease Expiration Date; or

(iii) with respect to a proposed sublease of less than the entire Premises for a sublease term ending during the last six (6) months of the Term, the right to terminate this Lease as to the portion of the Premises affected by such sublease on the effective date of the sublease, as though it were the Lease Expiration Date, in which case Tenant shall execute and deliver to Landlord an appropriate modification of this Lease, in form satisfactory to Landlord in all respects within ten (10) days of Landlord’s notice of partial termination, which modification of this Lease shall provide that the number of rentable square feet of the Premises shall be decreased by, and the Monthly Base Rent and Additional Rent payable by Tenant hereunder shall be adjusted in proportion to, the number of rentable square feet of the Premises affected by such termination, as determined by Landlord.

g. If Landlord exercises any of its options under Section 7.f., above, Landlord may then lease (or sublease) the Premises or any portion thereof to Tenant’s proposed assignee or subtenant, as the case may be, without any liability whatsoever to Tenant.

h. Except as otherwise expressly set forth in Sections 22 and 23, below, upon any assignment of this Lease or sublease of all or a portion of the Premises (except to an Affiliate of Tenant), any and all option rights, rights of first refusal, rights of first negotiation, and expansion rights shall terminate, it being understood that any and all such rights are personal to Tenant (and not to any assignee or subtenant) and are not appurtenant to the Premises or this Lease. Further, except as otherwise expressly set forth in Sections 22 and 23, below, Tenant shall not have the right to exercise any such rights unless Tenant (and not any assignee or subtenant of Tenant) shall be in occupancy of all of the Premises at the time of the exercise of any such right. In addition to the administrative fee described in Section 7.a.(7), above, Tenant shall reimburse Landlord for its reasonable attorneys’ fees (which fees shall in no event exceed Two Thousand Dollars ($2,000.00)) and other third party expenses incurred in reviewing any requested consent whether or not such consent is granted. Tenant shall not collaterally assign, mortgage, pledge, hypothecate or otherwise encumber this Lease or any of Tenant’s rights hereunder without the prior written consent of Landlord, which consent Landlord may withhold in its sole discretion.

i. Notwithstanding any consent by Landlord to an assignment or subletting, Tenant shall remain primarily liable for the performance of all covenants and obligations contained in this Lease. Each approved assignee or subtenant shall also automatically become liable for the obligations of Tenant hereunder. Landlord shall be permitted to enforce the provisions of this Lease directly against Tenant and/or against any assignee or sublessee without proceeding in any way against any other person. Collection or acceptance of Annual Base Rent or Additional Rent from any such assignee, subtenant or occupant shall not constitute a waiver or release of Tenant from the terms of any covenant or obligation contained in this Lease, hor shall such collection or acceptance in any way be construed to relieve Tenant from obtaining the prior written consent of Landlord to such assignment or subletting or any subsequent assignment or subletting.

j. Notwithstanding anything contained herein to the contrary, the consent requirement set forth in Section 7a, above, shall not be applicable to any assignment of this Lease or subletting of the Premises to an Affiliate (hereinafter defined) of Tenant; provided, however, that in each instance, Tenant shall give Landlord at least fifteen (15) days prior written notice of any proposed sublease or assignment to an Affiliate, which notice shall contain information and documentation reasonably acceptable to Landlord evidencing to Landlord’s reasonable satisfaction that the proposed assignee or subtenant is an Affiliate, and a copy of the proposed assignment or sublease document. As used herein, the term “Affiliate” shall refer to a person or entity that controls (hereinafter defined), is controlled by, or is under common control with Tenant. “Control” as used herein shall mean the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of the entity in question, whether through ownership of voting securities or by contract.

8. IMPROVEMENTS AND FIXTURES.

a. Tenant shall neither make nor allow any alterations, decorations, replacements, changes, additions or improvements (collectively referred to as “Alterations”) to the Premises or any part thereof that will or may affect the mechanical, electrical, plumbing, HVAC or other systems or the exterior or structure of the Building, without the prior written consent of Landlord, which may be withheld by Landlord in its sole discretion. Tenant shall not make or allow any other kind of Alterations to the Premises or any part thereof without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed. All of such Alterations, structural or otherwise, must conform to (i) the Construction Rules and Regulations (as defined in the Work Agreement); and (ii) such other rules and regulations as are established from time to time by Landlord. All Alterations must be performed in a good and workmanlike manner, must comply with all applicable building codes, laws and regulations (including, without limitation, the Americans With Disabilities Act, as amended), shall not require any changes to or modifications of any of the mechanical, electrical, plumbing, HVAC or other systems or the exterior or structure of the Building, and shall otherwise be constructed in strict accordance with the terms and conditions of this Section 8. Notwithstanding anything to the contrary contained herein, Tenant shall have the right to make Cosmetic Alterations (hereinafter defined) in or to the Premises without Landlord’s prior consent, but upon at least ten (10) days prior written notice to Landlord. As used herein, the term “Cosmetic Alterations” shall mean nonstructural Alterations in or to the Premises (e.g., paint, wallpaper or carpet) which are consistent with the design standards of the Tenant Improvements, which do not require a building permit to undertake, which cost in the aggregate less than Thirty Thousand Dollars ($30,000.00) to undertake, and which do not affect the structure or any of the systems of the Building. Tenant shall certify to Landlord in writing at least ten (10) days prior to undertaking any Cosmetic Alterations that the proposed Alterations are Cosmetic Alterations and describing the same in detail. If Landlord determines, in its reasonable discretion, that the proposed Alterations are not Cosmetic Alterations, Tenant shall request Landlord’s consent for such Alterations in accordance with this Section 8. If any Alterations made by or on behalf of Tenant requires Landlord to make any alterations or improvements to any part of the Building in order to comply with applicable law (including without limitation the Americans With Disabilities Act, as amended), Tenant shall pay all costs and expenses incurred by Landlord in connection with such alterations or improvements. Prior to undertaking any Alterations in the Premises, Tenant shall furnish to Landlord duplicate original policies or certificates thereof of worker’s compensation insurance (covering all persons to be employed by Tenant, and Tenant’s contractors and subcontractors in connection with such Alteration), builder’s all- risk insurance, and comprehensive public liability insurance (including property damage coverage) in such form, with such companies, for such periods and in such amounts as Landlord may reasonably require, naming Landlord and its agents, and any mortgagee as additional insureds.

b. It is understood and agreed by Landlord and Tenant that any Alterations undertaken in the Premises shall be constructed at Tenant’s sole expense. The costs of Alterations shall include, without limitation, the cost of all architectural work, engineering studies, materials, supplies, plans, permits and insurance. If requested by Landlord, Tenant shall provide to Landlord reasonably satisfactory evidence of Tenant’s ability to pay for such Alterations (including, but not limited to, a payment or performance bond). No consent by Landlord to any Alterations shall be deemed to be an agreement or consent by Landlord to subject Landlord’s interest in the Premises, the Building or the Land to any mechanic’s or materialman’s liens which may be filed in respect to such Alterations made by or on behalf of Tenant. If Landlord’s prior consent to any Alteration is required pursuant to the terms of this Section 8, and Landlord gives its consent as specified in Section 8.a., above, Landlord may impose as a condition to such consent such requirements as Landlord may deem reasonably necessary or desirable, in its sole discretion exercised in good faith, including, without limitation, the right to approve the plans and specifications for any work, supervision of the work by Landlord or its agents or by Landlord’s architect or contractor and, if Landlord or Landlord’s contractors undertake the construction of such Alteration, the payment to Landlord or its agents, architect or contractor of a reasonable construction supervision fee in connection therewith (provided, however, that Tenant shall not be obligated to pay Landlord, its agents, architects or contractors, such fee in connection with Tenant’s undertaking any Cosmetic Alterations), the right to require security for the full payment of any work and the right to impose requirements as to the manner in which or the time or times at which work may be performed. Landlord shall also have the right to approve the contractor or contractors who shall perform any Alterations, repairs in, to or about the Premises, such approval not to be unreasonably withheld, conditioned or delayed, and to post notices of non-responsibility and similar notices, as appropriate. Tenant shall reimburse Landlord for all of Landlord’s reasonable costs and expenses incurred in reviewing and approving Tenant’s plans and specifications for such Alterations within thirty (30) days after receipt of an invoice therefor. In addition, unless otherwise specifically agreed to in writing by and between Landlord and Tenant, immediately after completion of any Alterations, Tenant shall assign to Landlord any and all warranties applicable to such Alterations and shall provide Landlord with as-built plans of the Premises depicting such Alterations.

c. Tenant shall keep the Premises free from any liens arising out of any work performed on, or materials furnished to, the Premises, or arising from any other obligation incurred by Tenant. If any mechanic’s or materialmen’s lien is filed against the Premises, the Building and/or the Land for work claimed to have been done for or materials claimed to have been furnished to Tenant, such lien shall be discharged by Tenant within thirty (30) days thereafter, at Tenant’s sole cost and expense, by the payment thereof or by filing any bond required by law. If Tenant shall fail to timely discharge any such mechanic’s or materialman’s lien, Landlord may, at its option, discharge the same and treat the cost thereof as Additional Rent payable with the installment of rent next becoming due; it being expressly covenanted and agreed that such discharge by Landlord shall not be deemed to waive or release the default of Tenant in not discharging the same. Tenant shall indemnify and hold harmless Landlord, the Premises and the Building from and against any and all expenses, liens, claims, actions or damages to person or property in connection with any such lien or the performance of such work or the furnishing of such materials. Tenant shall be obligated to, and Landlord reserves the right to, post and maintain on the Premises at any time such notices as shall in the reasonable judgment of Landlord be necessary to protect Landlord against liability for all such liens or actions.

d. Unless otherwise specifically agreed to in writing by and between Landlord and Tenant, any Alterations of any kind to the Premises or any part thereof, except Tenant’s furniture and moveable trade fixtures, shall at once become part of the realty and belong to Landlord and shall be surrendered with the Premises, as a part thereof, at the end of the Term hereof; provided, however, that Landlord may, by written notice to Tenant at least thirty (30) days prior to the end of the Term, require Tenant to remove any Alterations (including all telecommunications cabling in the Premises or running between the Premises and any other portion of the Building) and to repair any damage to the Premises caused by such removal, all at Tenant’s sole expense. Any article of personal property, including business and trade fixtures, not attached to or built into the Premises, which were installed or placed in the Premises by Tenant at its sole expense, shall be and remain the property of Tenant and may be removed by Tenant at any time during the Term provided that Tenant repairs any damage to the Premises or the Building caused by such removal.

9. UTILITIES AND SERVICES.

a. Landlord shall furnish the following utilities and services to the Premises: electric current (for lighting and operation of normal desk-type office machines); hot and cold water; lavatory supplies; heat and air-conditioning during the appropriate seasons of the year as reasonably required; elevator service; and trash removal/cleaning and char service (after 6:00 p.m. on Monday through Friday, excluding Holidays). Heating and air conditioning shall be provided to the Premises only during the following days and hours (“Normal Business Hours”): (i) Monday through Friday 8:00 a.m. to 6:00 p.m., and (ii) Saturday 9:00 a.m. to 1:00 p.m., excluding Holidays. As used herein, the term “Holidays” shall mean New Year’s Day, Xxxxxx Xxxxxx Xxxx’x Birthday, President’s Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Thanksgiving Day and Christmas Day. At times other than the Normal Business Hours and days aforesaid, central air conditioning and heating shall be provided to Tenant upon at least twenty-four (24) hours prior notice from Tenant, and upon payment by Tenant of the hourly charge established by Landlord from time to time for each hour (or a portion thereof) of after-hours usage. The current hourly charge for each hour (or any portion thereof) of after-hours usage of central air conditioning and heating is Forty-Five Dollars ($45.00) per hour (or any portion thereof), which charge reasonably approximates the cost to Landlord of providing such after-hours service as of the Effective Date. Landlord shall use reasonable efforts to ensure that at least one (1) passenger elevator is operating in the Building twenty-four (24) hours per day, seven (7) days per week. All Building standard light bulbs and tubes in the Premises shall be replaced by Landlord and the cost thereof shall be included in Operating Expenses. In addition, Landlord may impose a reasonable additional charge for any additional or unusual services required to be provided by Landlord to Tenant because of the carelessness of Tenant, the nature of Tenant’s business or the removal of any refuse and rubbish from the Premises except for discarded material placed in wastepaper baskets and left for emptying as an incident to Tenant’s normal cleaning of the Premises. In the event that Landlord must temporarily suspend or curtail services because of accident and repair, Landlord shall have no liability to Tenant for such suspension or curtailment or due to any restrictions on use arising therefrom or relating thereto, and Landlord shall proceed diligently to restore such service. No interruption or malfunction of any such services shall constitute an actual or constructive eviction or disturbance of Tenant’s use and possession of the Premises, the Building or the parking garage or parking areas in or around the Building or constitute a breach by Landlord of any of its obligations hereunder or render Landlord liable for damages or entitle Tenant to be relieved from any of Tenant’s obligations hereunder (including the obligation to pay rent) or grant Tenant any right of setoff or claim against Landlord or constitute a constructive or other eviction of Tenant. Notwithstanding the foregoing, in the event that the interruption or cessation of any essential service(s) or utilities required to be provided by Landlord hereunder: (i) results from Landlord’s negligence or willful misconduct; (ii) is not caused by Tenant, its agents, employees, contractors or invitees; (iii) renders the Premises untenantable for Tenant’s business use therein; and (iv) exists for more than ten (10) consecutive business days, then, provided Tenant in fact ceases to use the Premises during the entirety of such period of cessation or interruption, commencing on the eleventh (11th) business day after such interruption, Monthly Base Rent hereunder shall be abated until such services or utilities are restored. The foregoing abatement of Monthly Base Rent shall be Tenant’s sole and exclusive remedy resulting from such interruption or cessation. In the event of any such interruption, Landlord shall use reasonable diligence to restore such services.

b. Except in any Electricity Meter Areas (hereinafter defined) in which submeters have been installed, Tenant will not, without the prior written consent of Landlord, use any apparatus or device in the Premises, including without limitation electric data processing machines, punch card machines and

machines using current in excess of 110 volts (or in excess of .60 kilowatt hours per square foot of usable area in the Premises per month, as determined by Landlord) which will in any way increase the amount of the electricity or water which would otherwise be furnished or supplied for the intended use of the Premises under this Section 9; and Tenant will not connect to electric current any apparatus or device for the purpose of using electric current or water, except through existing electrical outlets in the Premises or water pipes. If Tenant shall require water or electricity in excess of that which would otherwise be furnished or supplied for the intended use of the Premises, Tenant shall first secure the written consent of Landlord for the use thereof, which consent Landlord may not unreasonably withhold, but which consent may be conditioned by Landlord as set forth in this Section 9.b. Landlord may condition its consent on, among other things, the installation by Tenant at its sole cost of additional electric transformers and electric panels designated by Landlord (the “Additional Electrical Equipment”). Tenant shall be responsible for maintaining throughout the Term at Tenant’s sole cost all such Additional Electrical Equipment installed by Tenant (or, at Landlord’s sole option, by Landlord, at Tenant’s sole cost and expense). Furthermore, Landlord may condition its consent upon the requirement that a water meter or electric current meter be installed in the Premises, so as to measure the amount of water and electric current consumed for any such excess use. The parties acknowledge that the following areas within the Premises shall constitute “Electricity Meter Areas”: (i) all laboratory space (“Lab Space”) or space in which is located Tenant’s local area network (“LAN Space”); (ii) all portions of the Premises in which are located equipment which is or will be tied into the Supplemental HVAC System (hereinafter defined) or the Supplemental Electrical System (hereinafter defined); and (iii) all portions of the Premises in which the equipment therein is causing Excess Electricity Consumption (hereinafter defined). As used herein, the term “Supplemental Electrical System” means the 3000 amp electrical utility service (including but not limited to all feeder and distribution cables, busses and xxxx ducts, switchboards, transfer switches, disconnects, panel boards, circuit breakers, fuses, transformers, battery chargers, uninterruptible power supply (UPS) units, power distribution units (PDU), and generator sets) installed in the Building and on the roof of the Building. Tenant shall pay for all electricity consumed in the Electricity Meter Areas. Tenant shall be responsible for paying its proportionate share (which proportionate share shall be based on Tenant’s share of the distributed electrical capacity of the Supplemental Electrical System) all costs incurred by Landlord in repairing and maintaining the Supplemental Electrical System. The cost of all meters and submeters installed in the Premises, and the cost of installation, maintenance and repair thereof, the cost of any such utility use as shown by said meter, the cost of any new or additional utility installations, including, without limitation, wiring and plumbing, resulting from such utility use, and the cost of any additional expenses by Landlord incurred in keeping count of such utility use shall be paid by Tenant promptly upon demand by Landlord or, if Tenant is billed separately therefor, promptly upon receipt of a xxxx for same. Whenever heat generating machines or equipment are used in the Premises which affect the temperature otherwise maintained by the air conditioning system, Landlord reserves the right to install supplementary air conditioning units in the Premises and the cost thereof, including the cost of installation, operation and maintenance thereof, shall be paid by Tenant to Landlord upon demand by Landlord.

c. Tenant shall have the right to install and operate in the Premises personal computers and other electrically-operated office equipment normally used in modern offices. Subject to the provisions of Section 9.b, above, Tenant shall not install equipment of any kind or nature whatsoever nor engage in any practice or use which will or may necessitate any changes, replacements or additions to, or in the use of, the water system, heating system, plumbing system, air conditioning system, electrical system, floor load capacities, or other mechanical or structural system of the Premises or the Building without first obtaining the prior written consent of Landlord, which consent may be conditioned upon, but not limited to, Tenant first securing at its expense additional capacity for any said service in the Building; provided, however, Tenant shall be responsible for paying for any excess utility consumption arising from any such change, replacement, use or addition, such payments to be based on Landlord’s reasonable estimate or, at Landlord’s option, a submeter or similar device to measure such usage (said device to be installed at Tenant’s expense). Additionally, in the event that Landlord determines that Tenant’s electrical consumption exceeds standard office use (“Excess Electricity Consumption”), tenant shall pay the amount of such excess electrical consumption, as reasonably determined by Landlord, within thirty (30) days after demand therefor. Machines, equipment and materials belonging to Tenant which cause vibration, noise, cold, heat, fumes or odors that may be transmitted outside of the Premises to such a degree as to be objectionable to Landlord in Landlord’s sole opinion or to any other tenant in the Building shall be treated by Tenant at its sole expense so as to eliminate such objectionable condition, and shall not be allowed to operate until such time as the objectionable condition is remedied to Landlord’s satisfaction.

d. Tenant shall comply, at its sole cost and expense, with all orders, requirements and conditions now or hereafter imposed by any ordinances, laws, orders and/or regulations (hereinafter collectively called “regulations”) of any governmental body having jurisdiction over the Premises or the Building, whether required of Landlord or otherwise, regarding the collection, sorting, separation and recycling of waste products, garbage, refuse and trash (hereinafter collectively called “waste products”) including, but not limited to, the separation of such waste products into receptacles reasonably approved by Landlord and the removal of such receptacles in accordance with any collection schedules prescribed by such regulations. Landlord reserves the right (i) to refuse to accept from Tenant any waste products that are not prepared for collection in accordance with any such regulations, (ii) to require Tenant to arrange for waste product collection at Tenant’s sole cost and expense, utilizing a contractor reasonably satisfactory to Landlord, and (iii) to require Tenant to pay all costs, expenses, fines, penalties, or damages that may be imposed on Landlord or Tenant by reason of Tenant’s failure to comply with any such regulations. Notwithstanding the foregoing, if Tenant is unable to comply with Landlord’s standard procedures regarding the internal collection, sorting, separation and recycling of waste products, Landlord

shall use reasonable efforts to arrange for alternative procedures for Tenant, and Tenant shall pay Landlord all additional costs incurred by Landlord with respect thereto.

e. Throughout the Term, Tenant shall be provided with access to the Building and the Premises twenty-four (24) hours a day, 365 days a year, subject to applicable law and events of force majeure. The Building’s main entrance doors and elevators shall be equipped with a card reader security system or other similar security access system. Prior to the Commencement Date, Landlord shall provide Tenant with one hundred (100) access cards, at no cost to Tenant. Tenant shall be responsible for the cost of any additional or replacement access cards requested by Tenant. Subject to Landlord’s review and approval of the plans and specifications for such system, Tenant shall be entitled to install, at Tenant’s sole cost and expense, a card reader access system for the Premises, which Tenant shall be permitted to coordinate with the Building’s main security access system; provided that Tenant shall provide Landlord with a reasonable number of access cards by which Landlord may gain access to the Premises using Tenant’s card reader access system. Tenant hereby agrees to indemnify and hold Landlord and its agents, officers, directors and employees harmless from and against any cost, damage, claim, liability or expense (including attorneys’ fees) incurred by or claimed against Landlord and its agents, officers, directors and employees, directly or indirectly, as a result of or in any way arising from Tenant’s installation or use of such card reader access system.

f. Throughout the Term, Landlord shall cause the common areas of the Building (and the Sole Occupant Bathrooms) to be in compliance with all applicable laws, rules, orders, ordinances, regulations and requirements of all applicable governmental authorities now or hereafter in effect, unless such non-compliance is the result of (i) any act or omission of Tenant, its agents, contractors or employees, or (ii) Tenant’s particular use of the Premises.

g. As of the Commencement Date, all base-Building systems serving the Premises shall be in working order.

In connection with making any such installations, repairs, replacements, alterations, additions and improvements under the terms of this Section 10, Landlord shall, upon reasonable prior notice to Tenant (except in the event of an emergency, in which case no notice shall be required), have the right to access through the Premises as well as the right to take into and upon and through the Premises or any other part of the Building, all materials that may be required to make any such repairs, replacements, alterations, additions or improvements, as well as the right in the course of such work to close entrances, doors, corridors, elevators or other facilities located in the Building or temporarily to cease the operations of any services or facilities therein or to take portion(s) of the Premises reasonably necessary in connection with such work, without being deemed or held guilty of an eviction of Tenant; provided, however that Landlord agrees to use all reasonable efforts not to interfere

with or interrupt Tenant’s business operation in the Premises. Landlord shall have the right to install, use and maintain pipes and conduits in and through the Premises, including, without limitation, telephone and computer installations, provided that they do not permanently adversely affect (i) Tenant’s access to or use of the Premises, or (ii) the aesthetic appearance of the Premises. In connection with Landlord’s activities pursuant to this Section 10.b, Landlord will use reasonable efforts not to materially and adversely interfere with Tenant’s business operations in the Premises.

c. Except for injury or death to persons or damage to property caused by the negligence or willful misconduct of Landlord, its agents or employees, Landlord shall not be liable to Tenant for any expense, injury, loss or damage resulting from Landlord’s exercise of any rights under this Section 10, all claims against Landlord for any and all such liability being hereby expressly released by Tenant. Landlord shall not be liable to Tenant for damages by reason of interference with the business of Tenant or inconvenience or annoyance to Tenant or the customers of Tenant. The Rent reserved herein shall not xxxxx while the Landlord’s rights under this Section 10 are exercised, and Tenant shall not be entitled to any set-off or counterclaims for damages of any kind against Landlord by reason thereof, all such claims being hereby expressly released by Tenant.

d. Landlord shall have the right to use any and all means which Landlord may deem proper to open all of the doors in, upon and about the Premises, excluding Tenant’s vaults and safes, in any emergency in order to obtain entry to the Premises. Any entry to the Premises obtained by Landlord by any of said means shall not be construed or deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction of Tenant from the Premises or any portion thereof.

11. LIABILITY.

a. Except for injury or death to persons or damage to property caused by the negligence or willful misconduct of Landlord, its agents or employees, Landlord and its agents, officers, directors and employees assume no liability or responsibility whatsoever with respect to the conduct or operation of the business to be conducted in the Premises and shall have no liability for any claim of loss of business or interruption of operations (or any claim related thereto). Landlord and its agents, officers, directors and employees shall not be liable for any accident to or injury to any person or persons or property in or about the Premises which is caused by the conduct and operation of said business or by virtue of equipment or property of Tenant in said Premises. Tenant agrees to hold Landlord and its agents, officers, directors and employees harmless against all such claims, except to the extent resulting from Landlord’s negligence or willful misconduct. Landlord and its agents, officer, directors and employees shall not be liable to Tenant, its employees, agents, business invitees, licensees, customers, clients, family members or guests for any damage, compensation or claim arising out of or related to managing the Premises or the Building, repairing any portion of the Premises or the Building, the interruption in the use of the Premises, accident or damage resulting from the use or operation (by Landlord and its agents, officers, directors and employees, Tenant, or any other person or persons whatsoever) or failure of elevators, or heating, cooling, electrical or plumbing equipment or apparatus, or the termination of this Lease by reason of the destruction of the Premises, or from any fire, robbery, theft, mysterious disappearance and/or any other casualty, or from any leakage in any part of portion of the Premises or the Building, or from water, rain or snow that may leak into or flow from any part of the Premises or the Building, or from any other cause whatsoever, unless occasioned by the negligence or willful misconduct of Landlord, its agents or employees. In no event shall Landlord be liable for punitive or consequential damages, nor shall Landlord be liable with respect to utilities furnished to the Premises, or the lack of any utilities. Any goods, property or personal effects, stored or placed by Tenant in or about the Premises or in the Building, shall be at the sole risk of Tenant, and Landlord and its agents, officers, directors and employees shall not in any manner be held responsible therefor, except if such injury or damage results from the negligence or willful misconduct of Landlord, its agents or employees. The agents and employees of Landlord are prohibited from receiving any packages or other articles delivered to the Building for Tenant, and if any such agent or employee receives any such package or articles, such agent or employee shall be the agent of Tenant for such purposes and not of Landlord.

b. Tenant hereby agrees to indemnify and hold Landlord and its agents, officers, directors and employees harmless from and against any cost, damage, claim, liability or expense (including attorneys’ fees) incurred by or claimed against Landlord and its agents, officers, directors and employees, directly or indirectly, as a result of or in any way arising from (i) Tenant’s use and occupancy of the Premises or in any other manner which relates to the business of Tenant, including, but not limited to, any cost, damage, claim, liability or expense arising from any violation of any zoning, health, environmental or other law, ordinance, order, rule or regulation of any governmental body or agency; (ii) the negligence or willful misconduct of Tenant, its officers, directors, employees and agents; (iii) any default, breach or violation of this Lease by Tenant; or (iv) injury or death to individuals or damage to property sustained in or about the Premises.

c. Notwithstanding any other provision of this Lease to the contrary, Landlord and Tenant agree that in the event that the Building, the Premises or the contents thereof are damaged or destroyed by fire or other casualty, each party hereto waives its rights, if any, against the other party with respect to such damage or destruction to the extent such damage or destruction is covered under the property insurance policy(ies) of the party waiving such rights (or would have been covered had the party waiving such rights carried the property insurance required hereunder to be carried by such party). All policies of fire and/or extended coverage or other insurance covering the Premises or the contents thereof obtained by Landlord or Tenant shall contain a clause or endorsement providing in substance that (i) such insurance shall not be prejudiced if the insureds thereunder have waived in whole or in part the right of recovery from any person or persons prior to the date and time of loss or damage, if any, and (ii) the

insurer waives any rights of subrogation against Landlord (in the case of Tenant’s insurance policy) or Tenant (in the case of Landlord’s insurance policy), as the case may be.

12. INSURANCE.

a. Tenant shall maintain at all times during the Term hereof and at its sole cost and expense, broad-form commercial general liability insurance for bodily injury and property damage naming Landlord as an additional insured, in such amounts as are adequate to protect Landlord and Landlord’s managing agents against liability for injury to or death of any person in connection with the use, operation or condition of the Premises. Such insurance at all times shall be in an amount of not fewer than Five Million Dollars ($5,000,000) combined single limit aggregate for bodily injury or death or damage to property. If, in the reasonable opinion of the insurance broker retained by Landlord, the amount of public liability and property damage insurance coverage at any time during the Term is not adequate, Tenant shall increase the insurance coverage as reasonably required by Landlord’s insurance broker. In no event shall the limits of such policy be considered as limiting the liability of Tenant under this Lease.

b. Tenant shall at all times during the Term hereof maintain in effect policies of insurance covering the Tenant Improvements (including any Alterations, additions or improvements as may be made by Tenant after the Commencement Date), plate glass, trade fixtures, merchandise and all other personal property from time to time in or on the Premises, in an amount not less than one hundred percent (100%) of their actual replacement cost, providing protection against all risks covered by standard form of “Fire and Extended Coverage Insurance,” together with insurance against vandalism and malicious mischief. Tenant shall also maintain at its sole cost and expense xxxxxxx’x compensation insurance in the maximum amount required by law.

c. All insurance required to be carried by Tenant shall be issued by responsible insurance companies, qualified to do business in the Commonwealth of Virginia and reasonably acceptable to Landlord. Each policy shall name Landlord and the property management company retained by Landlord at the Building, as additional insureds, and shall contain a provision that the same may not be cancelled or reduced without providing Landlord not fewer than thirty (30) days prior written notice. Certificates of insurance (XXXXX 28 only) evidencing the existence and amounts of said insurance shall be delivered to Landlord no later than five (5) days prior to the Commencement Date, and renewals thereof shall be delivered to Landlord at least ten (10) days prior to the expiration of any such policy. If Tenant fails to adhere to the requirements of this Section 12, Landlord may order such insurance and charge the cost thereof to Tenant, which amount shall be deemed Additional Rent hereunder and shall be payable by Tenant upon demand. Tenant’s failure to provide and keep in force the aforementioned insurance shall be regarded as a material default hereunder, entitling Landlord to exercise any or all of the remedies provided in this Lease, Any policy may be carried under so-called “blanket coverage” form of insurance policies. Tenant shall obtain and furnish evidence to Landlord of the waiver by Tenant’s insurance carriers of any right of subrogation against Landlord and Landlord’s management company at the Building.

d. Each party hereby waives any and every right or cause of action for any and all loss of, or damage to, any of its property (whether or not such loss or damage is caused by the fault or negligence of the other party or anyone for whom said other party may be responsible), which loss or damage is covered by valid and collectible fire, extended coverage, “All Risk” or similar policies, maintained by such party or required to be maintained by such party under this Lease, but only to the extent that such loss or damage is recovered under said insurance policies (if such policy or policies have been obtained) or would have been recovered if such party had obtained the required insurance coverage hereunder. Written notice of the terms of said mutual waivers shall be given to each insurance carrier and said insurance policies shall be properly endorsed, if necessary, to prevent the invalidation of said insurance coverages by reason of said waivers.

e. During the Term, Landlord shall maintain a policy of casualty insurance covering the Building in such amounts and with such other coverages as are normally and customarily carried by prudent owners of comparable office buildings located in the Dulles Toll Road Corridor submarket.

13. FIRE OR CASUALTY.

a. If the Premises or any part thereof shall be damaged by fire or any other cause, Tenant shall give prompt notice thereof to Landlord. If, in the reasonable judgment of Landlord’s architect, restoration of the Premises is feasible within a period of nine (9) months from the date of the damage, and provided such damage was not caused by Tenant, its agents, servants or invitees, Landlord shall restore the Premises to the condition existing as of the Commencement Date, provided that adequate insurance proceeds are made available to Landlord. Tenant agrees to make all proceeds of Tenant’s insurance policies available to Landlord in accordance with Tenant’s insurance obligations set forth in Section 12, above. In addition, Tenant shall repair and restore, at Tenant’s sole expense, all Alterations, furniture, fixtures and other property of Tenant located in the Premises prior to such casualty. If the Premises are Unusable, in whole or in part, during such restoration, the Monthly Base Rent and Additional Rent hereunder shall be abated to the extent and for the period that the Premises are unusable; provided, however, that if such damage or destruction shall result from the act or omission of Tenant, its employees, agents or invitees, tenant shall not be entitled to any abatement of Monthly Base Rent or Additional Rent.

b. If restoration is not feasible in the reasonable judgment of Landlord’s architect within the aforesaid nine (9) month period, Landlord shall so notify Tenant, and Landlord and Tenant shall each have the right to terminate this Lease by giving written notice thereof to the other party within sixty (60) days after the occurrence of such damage, in which event this Lease and the tenancy hereunder shall terminate as of the date of such damage or destruction and the Monthly Base Rent and Additional Rent will be apportioned as of the date of such damage or destruction. If neither party exercises its right of termination, the Premises shall be restored as provided above. Landlord’s architect shall use reasonable efforts to determine, within sixty (60) days after the date of the casualty, the approximate amount of time that will be required in order to restore the Premises in accordance with the terms of this Lease.

c. In case the Building is so severely damaged by fire or other casualty (although the Premises may not be affected) that Landlord shall decide in its sole discretion not to rebuild or reconstruct such Building, then this Lease and the tenancy hereunder shall terminate on the date specified by Landlord in a notice given to Tenant no later than forty-five (45) days after the date of such casualty.

14. EMINENT DOMAIN.

If the Premises or any part thereof shall be taken or condemned by any governmental or quasi-governmental authority pursuant to the power of eminent domain or otherwise, Tenant shall make no claim for compensation in such proceedings and shall have no right to participate in any condemnation proceedings under any statutes, laws or ordinances of the Commonwealth of Virginia. All sums awarded or agreed upon between Landlord and the condemning authority for the taking of the interest of Landlord or Tenant, whether as damages or as compensation, will be the property of Landlord. In the event of such taking, Rent shall be paid to the date of vesting of title in the condemning authority. Notwithstanding the foregoing, Tenant may assert any claim that it may have against the condemning authority for compensation for any fixtures and personalty owned by Tenant (which were not paid for out of the proceeds of the Improvement Allowance) and for any relocation expense compensable by statute, and receive such award therefor as may be allowed in the condemnation proceedings, if such award shall be made in addition to, and stated separately from, the award made for the Land and the Building or the part thereof so taken, and shall not reduce any award otherwise payable to Landlord.

15. SUBORDINATION AND ESTOPPEL CERTIFICATES.

a. This Lease shall be subject and subordinate at all times to all ground or underlying leases which now exist or may hereafter be executed affecting the Building or any part thereof or the Land, and to the lien of any mortgages or deeds of trust in any amount or amounts whatsoever now or hereafter placed on or against the Building or any part thereof or the Land, or on or against Landlord’s interest or estate therein or on or against any ground or underlying lease without the necessity of having further instruments on the part of Tenant to effect such subordination. Upon request of Landlord, Tenant will execute any further written instrument necessary to subordinate its rights hereunder to any such underlying leases or liens. If, at any time, or from time to time during the Term, any mortgagee shall request that this Lease have priority over the lien of such mortgage, and if Landlord consents thereto, this Lease shall have priority over the lien of such mortgage and all renewals, modifications, replacements, consolidations and extensions thereof and all advances made thereunder and interest thereon, and Tenant shall, within ten (10) business days after receipt of a request therefor from Landlord, execute, acknowledge and deliver any and all documents and instruments confirming the priority of this Lease. In any event, however, if this Lease shall have priority over the lien of a first mortgage, this Lease shall not become subject or subordinate to the lien of any subordinate mortgage, and Tenant shall not execute any subordination documents or instruments for any subordinate mortgagee, without the written consent of the first mortgagee. Notwithstanding the foregoing, the subordination of the Lease pursuant to this Section 15.a shall be conditioned upon the receipt by Tenant from the current mortgagee of a subordination non-disturbance and attornment agreement (“SNDA”) for Tenant’s benefit on such mortgagee’s standard form of SNDA. Throughout the Term, upon Tenant’s written request, Landlord shall use reasonable efforts to obtain from any future mortgagee a SNDA for Tenant’s benefit on such mortgagee’s standard form of SNDA. Tenant shall pay for (or reimburse Landlord for) all costs (including reasonable attorneys’ fees) incurred by Landlord or any such mortgagee in connection with the negotiation and drafting of any such SNDA, whether or not Landlord is ultimately able to obtain same for Tenant’s benefit.

b. In the event of: (i) a transfer of Landlord’s interest in the Building, (ii) the termination of any ground or underlying lease of the Building, or the Land, or both, or (iii) the purchase or other acquisition of the Building, or Landlord’s interest therein in a foreclosure sale or by deed in lieu of foreclosure under any mortgage or deed of trust, or pursuant to a power of sale contained in any mortgage or deed of trust, then in any of such events Tenant shall, at the request of Landlord or Landlord’s successor in interest, attorn to and recognize the transferee or purchaser of Landlord’s interest or the interest of the lessor under the terminated ground or underlying lease, as the case may be, as “Landlord” under this Lease for the balance then remaining of the Term, and thereafter this Lease shall continue as a direct lease between such person or entity, as “Landlord,” and Tenant, as “Tenant,” except that such lessor, transferee or purchaser shall not be liable for any act or omission of Landlord before such lease termination or before such person’s succession to title, nor be subject to any offset, defense or counterclaim accruing before such lease termination or before such person’s succession to title, nor be bound by any payment of Monthly Base Rent or Additional Rent before such lease termination or before such person’s succession to title for more than one month in advance.

c. Tenant agrees, at any time, and from time to time, upon not fewer than fifteen (15) days prior notice by Landlord, to execute, acknowledge and deliver to Landlord, a statement in writing

certifying, to the extent accurate, that (i) this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications); (ii) the Term of the Lease has commenced and the full rental is now accruing hereunder; (iii) Tenant has accepted possession of the Premises and is presently occupying the same; (iv) all improvements required by the terms of the Lease to be made by Landlord have been completed and all tenant improvement allowances have been paid in full; (v) there are no offsets, counterclaims, abatements or defenses against or with respect to the payment of any rent or other charges due under the Lease; (vi) no rent under the Lease has been paid more than thirty (30) days in advance of its due date; (vii) to the best of the knowledge of the Tenant, Landlord is not in default in the performance of any covenant, agreement, provision or condition contained in the Lease or, if so, specifying each such default of which Tenant may have knowledge; (viii) the address for notices to be sent to Tenant; (ix) the only security deposit tendered by Tenant is as set forth in the Lease, and such security deposit has been paid to Landlord; and (x) any other information reasonably requested by Landlord or any mortgagee or ground lessor of the Building and/or the Land it being intended that any such statement delivered pursuant hereto may be relied upon by any prospective purchaser or lessee of the Building or any part thereof, any mortgagee or prospective mortgagee thereof, any prospective assignee of any mortgage thereof, any ground lessor or prospective ground lessor of the Land and/or the Building, or any prospective assignee of any such ground lease. Tenant also agrees to execute and deliver from time to time such estoppel certificates as an institutional lender may reasonably require with respect to this Lease.

16. DEFAULT AND REMEDIES.

a. If Tenant shall (i) fail to pay any installment of Monthly Base Rent, although no legal or formal demand has been made therefor, within five (5) calendar days after the due date therefor, or (ii) fail to make any payment of Additional Rent or any other payment required by the terms and provisions hereof, within five (5) days after notice or demand therefor; or (iii) convey, assign, mortgage or sublet this Lease, the Premises or any part thereof, or Tenant’s interest therein, or attempt any of the foregoing, without the prior written consent of Landlord; or (iv) abandon the Premises for a period of ten (10) consecutive calendar days (coupled with the non-payment of Rent as such amounts become due pursuant to the terms of this Lease); or (v) commit or suffer to exist an Event of Bankruptcy (hereinafter defined), or (vi) fail to maintain the insurance coverage required by Section 12, above, or (vii) violate or fail to perform any of the other terms, conditions, covenants, or agreements herein made by Tenant and fails to cure such default within thirty (30) calendar days after notice, provided, however, that if the nature of Tenant’s failure is such that more than thirty (30) days are reasonably required for its cure, then Tenant shall not be in default if it begins such cure within the thirty (30) day period described above and thereafter diligently prosecutes such cure to completion within an additional thirty (30) days; then there shall be deemed to have been committed an “Event of Default”. Notwithstanding the foregoing cure periods, in the event that Tenant breaches its covenant set forth in Section 6.a. hereof on more than two (2) occasions in any nine (9) consecutive month period, then any subsequent breach of such covenant during the Term of this Lease shall be deemed to be an immediate Event of Default. Upon an Event of Default, at Landlord’s option, this Lease shall terminate, without prejudice however, to the right of Landlord to recover from Tenant all rent and any other sums accrued up to the later of: (1) the date of termination of this Lease or (2) the date Landlord recovers possession of the Premises, and without release of Tenant from any indemnification obligations to Landlord under this Lease, which indemnification obligations arose or accrued prior to the later of: (a) the date of termination of this Lease or (b) the date Landlord recovers possession of the Premises. The foregoing is not intended to, and shall not, limit Landlord in the exercise of any other remedy for such immediate Event of Default.

b. In the event of any Event of Default by Tenant as defined in Section 16.a., Landlord may at any time thereafter, without notice and demand and without limiting Landlord in the exercise of any other right or remedy which Landlord may have by reason of such default or breach do any of the following:

(i) Landlord may terminate this Lease, by giving written notice of such termination to Tenant, whereupon this Lease shall automatically cease and terminate and Tenant shall be immediately obligated to quit the Premises. Any other notice to quit or notice of Landlord’s intention to re-enter the Premises is hereby expressly waived. If Landlord elects to terminate this Lease, everything contained in this Lease on the part of Landlord to be done and performed shall cease without prejudice, subject, however, to the right of Landlord to recover from Tenant all rent and any other sums accrued up to the time of termination or recovery of possession by Landlord, whichever is later.

(ii) With or without the termination of this Lease, Landlord may proceed to recover possession of the Premises under and by virtue of the provisions of the laws of the jurisdiction in which the Building is located, or by such other proceedings, including re-entry and possession, as may be applicable. If this Lease is terminated or Landlord recovers possession of the Premises before the expiration of the Term by reason of Tenant’s default as hereinabove provided, or if Tenant shall abandon or vacate the Premises before the Lease Expiration Date for a period of ten (10) consecutive calendar days (coupled with the non-payment of Rent as such amounts become due pursuant to the terms of this Lease), Landlord shall have the option to take reasonable steps to relet the Premises for such rent and upon such terms as are not unreasonable under the circumstances and, if the full rental reserved under this Lease (and any of the costs, expenses or damages indicated below) shall not be realized by Landlord, Tenant shall be liable for all damages sustained by Landlord, including, without limitation, deficiency in rent during any period of vacancy or otherwise; the costs of removing and storing the property of Tenant or of any other occupant; all reasonable expenses incurred by Landlord in enforcing Landlord’s remedies, including, without limitation, reasonable attorneys’ fees and Late Charges as provided herein, and advertising, brokerage fees and expenses of placing the Premises in first class

rentable condition. Landlord, in putting the Premises in good order or preparing the same for rerental may, at Landlord’s option, make such alterations, repairs, or replacements in the Premises as Landlord, in its sole judgment, considers advisable and necessary for the purpose of reletting the Premises, and the making of such alterations, repairs, or replacements shall not operate or be construed to release Tenant from liability hereunder as aforesaid. If Tenant requests in writing that Landlord attempt to relet the Premises after an Event of Default by Tenant hereunder and Tenant states in such writing that an Event of Default has occurred and is continuing under the Lease, Landlord agrees to use commercially reasonable efforts to relet the Premises to another tenant (a “Substitute Tenant”) on terms and conditions determined by Landlord in its sole discretion; provided, however, notwithstanding anything contained herein to the contrary (a) Landlord shall have no obligation to solicit or entertain negotiations with any other prospective tenants for the Premises until Landlord obtains full and complete possession of the Premises; (b) Landlord shall not be obligated to offer the Premises to a prospective tenant when other premises in the Building suitable for that prospective tenant’s use are (or soon will be) available; (c) Landlord may, but shall not be obligated to, lease the Premises to a Substitute Tenant for a rental less than the current fair market rental then prevailing for similar office uses in comparable buildings in the same market area as the Building, nor shall Landlord be obligated to enter into a new lease under other terms and conditions that are unacceptable to Landlord in its sole discretion; (d) Landlord shall not be obligated to enter into a lease with any proposed tenant whose use would: (1) violate any restriction, covenant or requirement contained in the lease of another tenant of the Building; (2) adversely affect the reputation of the Building; or (3) be incompatible with the operation of the Building as a first class building; and (e) Landlord shall not be obligated to enter into a lease with any proposed Substitute Tenant which does not have, in Landlord’s reasonable opinion, sufficient financial resources or operating experience to operate the Premises in a first class manner and pay all Rent on time and fulfill all of its obligations under such new lease. Tenant agrees to use commercially reasonable efforts to mitigate any damages that Tenant may suffer as a result of any default by Landlord hereunder.

(iii) Any damage or loss of rent sustained by Landlord may be recovered by Landlord, at Landlord’s option, at the time of termination of this Lease, the time of the reletting, or in separate actions, from time to time, as said damage shall have been made more easily ascertainable by successive relettings, or at Landlord’s option in a single proceeding deferred until the expiration of the Term (in which event Tenant hereby agrees that the cause of action shall not be deemed to have accrued until the date of expiration of said Term) or in a single proceeding prior to either the time of reletting or the expiration of the Term. If the Landlord elects to repossess the Premises without terminating this Lease, then Tenant shall be liable for and shall pay to Landlord all Rent and other indebtedness accrued to the date of such repossession, plus Rent required to be paid by Tenant to Landlord during the remainder of this Lease until the date of expiration of the Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during such period (after deducting expenses incurred by Landlord as provided in Section 16.b,(ii), above). In no event shall Tenant be entitled to any excess of any Rent obtained by reletting over and above the Rent herein reserved. Actions to collect amounts due from Tenant as provided in this Section 16.a.(iii) may be brought from time to time, on one or more occasions, without the necessity of Landlord’s waiting until expiration of this Lease term.

c. Notwithstanding the foregoing, if Landlord terminates this Lease pursuant to Section 16.b.(i), above, Landlord shall be entitled to recover from Tenant, and Tenant shall pay to Landlord on demand, as and for liquidated and agreed final damages for Tenant’s default, an amount equal to the difference between (i) all Monthly Base Rent, Additional Rent and other sums which would be payable under this Lease from the date of such demand (or, if it is earlier, the date to which Tenant shall have satisfied in full its obligations under Section 16.b.(ii), above) for what would be the then unexpired Term in the absence of such termination, and (ii) the fair market rental value of the Premises over the same period (net of all expenses and all vacancy periods reasonably projected by Landlord to be incurred in connection with the reletting of the Premises), with such differential discounted at the rate of seven percent (7%) per annum. Nothing herein shall be construed to affect or prejudice Landlord’s right to prove, and claim in full, unpaid Rent or any other amounts accrued prior to termination of this Lease.

d. Notwithstanding anything herein to the contrary, upon the occurrence of an Event of Default hereunder, Landlord, with or without terminating the Lease, may immediately reenter and take possession of the Premises and evict Tenant therefrom in accordance with applicable law, without being liable for or guilty of trespass, forcible entry or any other tort.

e. Tenant hereby expressly waives any and all rights of redemption granted by or under any present of future laws in the event Tenant is evicted or dispossessed for any cause, or in the event Landlord obtains possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease or otherwise. In addition, Tenant hereby expressly waives any and all rights to bring any action whatsoever against any tenant taking possession after Tenant has been dispossessed or evicted hereunder, or to make any such tenant or party to any action brought by Tenant against Landlord.

f. Landlord and Tenant shall and each does hereby waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other on any matters whatsoever arising out of or in any way connected with this Lease or its termination, the relationship of Landlord and Tenant, Tenant’s use or occupancy of the Premises or any claim of injury or damage and any emergency statutory or any other statutory remedy. In the event Landlord commences any summary proceeding for nonpayment of Rent or Additional Rent, or commences any other action or proceeding against Tenant in connection with this Lease, Tenant will interpose no counterclaim of whatever nature or description in any such proceeding, except mandatory counter-claims.

g. Nothing contained herein shall prevent the enforcement of any claim Landlord may have against Tenant for anticipatory breach of the unexpired Term. In the event of a breach or anticipatory breach by Tenant of any of the covenants or provisions hereof, Landlord shall have the right of injunction and the right to invoke any remedy allowed at law or in equity as if reentry, summary proceedings and other remedies were not provided for herein.

h. In the event of any default by Landlord, Tenant’s exclusive remedy shall be an action for damages (Tenant hereby waiving the benefit of any laws granting Tenant a lien upon the property of Landlord or upon Rent due Landlord), but prior to any such action Tenant will give Landlord and any mortgagee notice specifying such default with particularity, and Landlord and/or such mortgagee shall have thirty (30) days after receipt of such notice in which to cure any such default; provided, however, that if such default cannot, by its nature, be cured within such period, Landlord shall not be deemed in default if Landlord and/or such mortgagee shall within such period commence to cure such default and shall diligently prosecute the same to completion. Unless and until Landlord and/or any mortgagee fails so to cure any default after notice, Tenant shall have no remedy or cause of action by reason thereof. All obligations of Landlord hereunder will be construed as covenants, not conditions; all such obligations will be binding upon Landlord only during the period of its ownership of the Building and not thereafter (provided that any uncured default by Landlord of any of its obligations hereunder which occurs during Landlord’s ownership of the Building shall not be extinguished as a result of the transfer or any other disposition of the Building by Landlord, unless any purchaser, transferee or subsequent owner of the Building assumes the obligations of Landlord under this Lease); and no default or alleged default by Landlord shall relieve or delay performance by Tenant of its obligations to continue to pay Annual Base Rent and Additional Rent hereunder as and when the same shall be due.

17. BANKRUPTCY.

a. For purposes of this Lease, the following shall be deemed “Events of Bankruptcy”: (i) if a receiver or custodian is appointed for any or all of Tenant’s property or assets, or if there is instituted a foreclosure action on any of Tenant’s property; or (ii) if Tenant files a voluntary petition under 11 U.S.C. Article 101, et seq., as amended (the “Bankruptcy Code”), or under the insolvency laws of any jurisdiction (the “Insolvency Laws”); or (iii) if there is filed an involuntary petition against Tenant as the subject debtor under the Bankruptcy Code or Insolvency Laws, which is not dismissed within sixty (60) days of filing; or (iv) if Tenant makes or consents to an assignment of its assets, in whole or in part, for the benefit of creditors, or a common law composition of creditors.

b. Upon the occurrence of an Event of Bankruptcy, Landlord, at its option and sole discretion, may terminate this Lease by written notice to Tenant (subject, however to applicable provisions of the Bankruptcy Code or Insolvency Laws during the pendency of any action thereunder). If this Lease is terminated under this Section 17, Tenant shall immediately surrender and vacate the Premises, waives all statutory or other notice to quit, and agrees that Landlord shall have all rights and remedies against Tenant provided in Section 16 in case of an Event of Default by Tenant.

c. If Tenant becomes the subject debtor in a case pending under the Bankruptcy Code (the “Bankruptcy Case”), Landlord’s right to terminate this Lease under this Section 17 shall be subject to the applicable rights (if any) of the debtor-in-possession or the debtor’s trustee in bankruptcy (collectively, the “Trustee”) to assume or assign this Lease as then provided for in the Bankruptcy Code, however, the Trustee must give to Landlord, and Landlord must receive, proper written notice of the Trustee’s assumption or rejection of this Lease, within sixty (60) days (or such other applicable period as is provided pursuant to the Bankruptcy Code) after the commencement of the Bankruptcy Case; it being agreed that failure of the Trustee to give notice of such assumption hereof within said period shall conclusively and irrevocably constitute the Trustee’s rejection of this Lease and waiver of any right of the Trustee to assume or assign this Lease. The Trustee shall not have the right to assume or assign this Lease unless said Trustee (i) promptly and fully cures all defaults under this Lease, (ii) promptly and fully compensates Landlord and any third party (Including other tenants) for all monetary damages incurred as a result of such default, and (iii) provides to Landlord “adequate assurance of future performance.” Landlord and Tenant (which term may include the debtor or any permitted assignee of debtor) hereby agree in advance that “adequate assurance of performance” as used in this paragraph, shall mean that all of the following minimum criteria must be met: (1) the source of Monthly Base Rent, Additional Rent, and other consideration due under this Lease, and the financial condition and operating performance of Tenant, and its guarantor, if any, shall be similar to the financial condition and operating performance of Tenant as of the Commencement Date; (2) Trustee or Tenant must pay to Landlord all Monthly Base Rent and Additional Rent payable by Tenant hereunder in advance pursuant to the terms of this Lease, (3) Trustee or Tenant must agree (by writing delivered to Landlord) that the use of the Premises shall be used only for the permitted use as stated in this Lease, and that any assumption or assignment of this Lease is subject to all of the provisions thereof and will not violate or affect the rights or agreements of any other tenants or occupants in the Building or of Landlord (including any mortgage or other financing agreement for the Building, (4) Trustee or Tenant must pay to Landlord at the time the next Monthly Base Rent is due under this Lease, in addition to such installment of Monthly Base Rent, an amount equal to the installments of Monthly Base Rent and Additional Rent due under this Lease for the next four (4) months of this Lease, said amount to be held by Landlord in escrow until either Trustee or Tenant defaults in its payment of Monthly Base Rent and Additional Rent or other obligations under this Lease (whereupon Landlord shall have the right to draw on such escrowed funds) or until the expiration of this Lease (whereupon the funds shall be returned to Trustee or Tenant except to the extent the funds have been drawn and not replaced); and (5) Trustee or Tenant must agree to pay to Landlord at any time Landlord is authorized to and does draw oh the escrow account the amount necessary to restore such escrow account to the original level required by clause (4), above. The criteria stated above are not

intended to be exhaustive or all-inclusive and Landlord may reasonably determine that the circumstances of Tenant or of this Lease require other or further assurances of future performance. In the event Tenant is unable to: (a) cure its defaults, (b) reimburse Landlord for its monetary damages, (c) pay the Monthly Base Rent and Additional Rent due under this Lease on time, or (d) meet that criteria and obligations imposed by (1) through (5), above, then Tenant hereby agrees in advance that it has not met its burden to provide adequate assurance of future performance, and this Lease may be terminated by Landlord in accordance with Section 17.b., above.

18. PAYMENT OF TENANT’S OBLIGATIONS BY LANDLORD AND UNPAID RENT.

All covenants and agreements to be performed by Tenant under any of the terms of this Lease shall be performed by Tenant at Tenant’s sole cost and expense. If Tenant shall fail to pay any sum of money, other than Rent, required to be paid by it hereunder or shall fail to perform any other act on its part to be performed hereunder, and such failure shall continue beyond, any applicable grace period set forth in this Lease, Landlord may, without waiving or releasing Tenant from any of its obligations hereunder, make any such payment or perform any such other required act on Tenant’s part. All sums so paid by Landlord, and all necessary incidental costs, together with interest thereon at two percentage points (2%) over the Prime Rate then in effect, from the date of such payment by Landlord, shall be payable by Tenant to Landlord as Additional Rent hereunder, upon receipt of an invoice therefor, and Tenant covenants and agrees to pay any such sums. Landlord shall have (in addition to any other right or remedy of Landlord hereunder or at law) the same rights and remedies in the event of the nonpayment thereof by Tenant as in the case of default by Tenant in the payment of Additional Rent. In addition, any Rent, including, without limitation, Annual Base Rent, Additional Rent, Tenant’s Pass-Through Costs and/or Late Charges, which is not paid timely will accrue interest per annum at two percentage points (2%) over the Prime Rate from the date such payment is due until the date paid in full (including all accrued interest).

19. VOLUNTARY SURRENDER.

The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and shall, at the sole option of Landlord, terminate all or any existing subleases or subtenancies, or may, at the sole option of Landlord, operate as an assignment to Landlord of any or all such subleases or subtenancies; provided however, that if Landlord elects to treat such termination as an assignment of any such sublease, Landlord shall have no obligation or liability to the subtenant thereunder for any claim, damage or injury which accrued prior to the date of surrender or mutual cancellation hereunder.

20. ABANDONMENT OF PERSONAL PROPERTY.

Upon the expiration of the Term or earlier termination of this Lease, Tenant shall forthwith remove Tenant’s goods and effects and those of any other persons claiming through or under Tenant, or subtenancies assigned to it, and quit and deliver the Premises to the Landlord peaceably and quietly. Goods and effects not removed by Tenant after termination of this Lease (or within forty-eight (48) hours after a termination by reason of Tenant’s default) shall be considered abandoned. Landlord shall give Tenant notice of right to reclaim abandoned property pursuant to applicable local law and may thereafter dispose of the same as Landlord deems expedient, including public or private sale and/or storage in a public warehouse or elsewhere at the sole cost, and for the account, of Tenant, and Tenant shall promptly upon demand reimburse Landlord for any expenses incurred by Landlord in connection therewith, including reasonable attorneys’ fees.

21. HOLD-OVER.

If Tenant shall not immediately surrender the Premises at the expiration of the Term then Tenant shall, by virtue of the provisions of this Section 21, become a tenant by the month. In such event Tenant shall be required to pay one hundred fifty percent (150%) of the amount of the Monthly Base Rent then in effect and as subsequently escalated in accordance with the provisions hereof, together with all Additional Rent in effect during the last month of the Term commencing said monthly tenancy with the first day next after the end of the Term; and said Tenant, as a month-to-month tenant, shall be subject to all of the conditions and covenants of this Lease as though the same had originally been a monthly tenancy, except as otherwise provided above with respect to the payment of Rent. Each party hereto shall give to the other at least thirty (30) days written notice to quit the Premises, except in the event of non-payment of Rent provided for herein when due, or of the breach of any other covenant by the said Tenant, in which event, Tenant shall not be entitled to any notice to quit, the usual thirty (30) days notice to quit being expressly waived; provided, however, that in the event that Tenant shall hold over after expiration of the Term, and if Landlord shall desire to regain possession of said Premises promptly at the expiration of the Term, then at any time prior to the acceptance of the Rent by Landlord from Tenant, as a monthly tenant hereunder, Landlord, at its election or option, may reenter and take possession of the Premises forthwith, without process, or by any legal action or process in the Commonwealth of Virginia.

22. OPTION TO EXTEND TERM.

a. Tenant shall have and is hereby granted the option to extend the Term hereof for two (2) periods of five (5) years each (each, an “Extension Period”) commencing on the date immediately following the Lease Expiration Date, or on the date immediately following the last day of the first Extension Period, as applicable, provided that: (i) Tenant delivers written notice (the “Extension Notice”)

to Landlord, not more than fifteen (15), or less than twelve (12), months prior to the Lease Expiration Date, or prior to last day of the first Extension Period, as applicable, time being of the essence, of Tenant’s irrevocable election to exercise such extension option (provided, however, that if the Premises contains more than 63,492 rentable square feet, Tenant shall deliver the Extension Notice to Landlord not more than eighteen (18), or less than fifteen (15), months prior to the Lease Expiration Date, or prior to last day of the first Extension Period, as applicable); (ii) no event exists at the time of the exercise of such option or arises subsequent thereto, which event by notice and/or the passage of time would constitute an Event of Default if not cured within the applicable cure period; and (iii) Tenant has not assigned its interest in the Lease or sublet more than thirty-five percent (35%) of the Premises (except to an Affiliate of Tenant. Notwithstanding the foregoing, Tenant may elect to extend the Term hereof pursuant to the terms of this Section 22 with respect to the entire Premises, or alternatively, with respect to any full floor(s) which comprise the Premises as of the date Tenant delivers the Extension Notice to Landlord, which notice shall set forth the portion of the Premises which shall be subject to the applicable Extension Period. Notwithstanding the foregoing, if Tenant delivers to Landlord, not more than nineteen (19), or less than sixteen (16), months prior to the Lease Expiration Date, or prior to the last day of the first Extension Period, as applicable, written notice (the “Extension Period Proposed Rent Notice”) requesting that Landlord furnish Tenant with Landlord’s proposed Annual Base Rent, Base Year and other material economic terms and conditions for the first or second (2^nd) Extension Period, as applicable, Landlord shall furnish Tenant with such proposed terms and conditions within thirty (30) days after Landlord’s receipt of the Extension Period Proposed Rent Notice (provided, however, that if the Premises contains more than 63,492 rentable square feet, Tenant shall deliver the Extension Period Proposed Rent Notice to Landlord not more than twenty-one (21), or less than eighteen (18), months prior to the Lease Expiration Date, or prior to last day of the first Extension Period, as applicable).

b. All terms and conditions of the Lease, including without limitation all provisions governing the payment of Additional Rent and annual increases in Annual Base Rent, shall remain in full force and effect during the any Extension Period, except that (i) Annual Base Rent (on a per rentable square foot basis) payable during each Extension Period shall equal the Fair Market Rental Rate (hereinafter defined) at the time of the commencement of the applicable Extension Period; (ii) Landlord shall provide a “market” improvement allowance, rental abatement and other tenant concessions in connection with the Extension Period; and (iii) the “Base Year” for Tenant’s Proportionate Share of increases in Operating Expenses and Tenant’s Proportionate Share of increases in Real Estate Taxes shall be mutually determined by and between Landlord and Tenant. As used in this Lease, the term “Fair Market Rental Rate” shall mean the fair market rental rate that would be agreed upon between a landlord and a tenant entering into a lease for comparable space as to location, configuration, size and use, in a comparable building as to quality, reputation and age which is located in the Dulles Toll Road Corridor submarket, with a comparable build-out and a comparable term assuming the following: (A) the landlord and tenant are informed and well-advised and each is acting in what it considers its own best interests; (B) the landlord shall provide a “market” tenant improvement allowance, free rent period and other tenant concessions typically provided to tenants of comparable space in comparable buildings for leases having terms comparable to the applicable Extension Period; and (C) the tenant will continue to pay its proportionate share of increases (over a new “Base Year” as negotiated by and between Landlord and Tenant) in Operating Expenses and Real Estate Taxes as described above.

c. Landlord and Tenant shall negotiate in good faith to determine the Annual Base Rent for each Extension Period, for a period of thirty (30) days after the date on which Landlord receives the Extension Notice. In the event Landlord and Tenant are unable to agree upon the Annual Base Rent for any Extension Period within said thirty (30)-day period, the Fair Market Rental Rate for the Premises shall be determined by a board of three (3) licensed real estate brokers, one of whom shall be named by the Landlord, one of whom shall be named by Tenant, and the two so appointed shall select a third (the ‘Third Broker”). Each real estate broker so selected shall be licensed in the Commonwealth of Virginia as a real estate broker specializing in the field of office leasing in Fairfax County, having no fewer than ten (10) years experience in such field, and recognized as ethical and reputable within the field. Landlord and Tenant agree to make their appointments promptly within ten (10) days after the expiration of the thirty (30)-day period, or sooner if mutually agreed upon. The two (2) brokers selected by Landlord and Tenant shall select the Third Broker within ten (10) days after they both have been appointed, and all three (3) brokers shall, within fifteen (15) days after the Third Broker is selected, submit his or her determination of the Fair Market Rental Rate. The Third Broker shall determine which determination of Fair Market Rental Rate made by Landlord’s broker or Tenant’s broker is closest to the determination of Fair Market Rental Rate made by the Third Broker (the “Closest Determination”). The Fair Market Rental Rate hereunder shall be the mean of the Closest Determination and the determination of Fair Market Rental Value made by the Third Broker. Landlord and Tenant shall each pay the fee of the broker selected by it, and they shall equally share the payment of the fee of the Third Broker.

d. Should the Term of the Lease be extended hereunder, Tenant shall, if required by Landlord, execute an amendment (the “Extension Amendment”) modifying the Lease within ten (10) business days after Landlord presents same to Tenant, which Extension Amendment shall accurately set forth the Annual Base Rent for each year of the applicable Extension Period and the other economic terms and provisions in effect during such Extension Period, as determined pursuant to the terms of this Section 22. Should Tenant fail to execute the Extension Amendment (which Extension Amendment accurately sets forth the terms and provisions in effect during the applicable Extension Period) within ten (10) business days after presentation of same by Landlord, time being of the essence, Tenant’s right to extend the Term of the Lease shall, at Landlord’s sole option, terminate, and Landlord shall be permitted to lease such space to any other person or entity upon whatever terms and conditions are acceptable to Landlord in its sole discretion.

23. RIGHT OF FIRST OFFER.

a. Subject to (i) any expansion rights, renewal rights, rights of first offer or refusal or other rights possessed by any tenant in the Building with respect to the Right of First Offer Space (hereinafter defined) or any portion thereof existing as of the Effective Date, (ii) any renewal rights granted by Landlord after the Effective Date to any tenant of all or any portion of the Right of First Offer Space, and (iii) the right of any tenant of the Right of First Offer Space (or any portion thereof) to negotiate an extension of the term of its lease of such space or a new lease demising such space, Tenant shall be granted during the initial Term the following rights with respect to the Right of First Offer Space. As used herein, the term “Right of First Offer Space” shall mean any space in the Building (other than the Premises) which becomes available for lease by third parties with respect to which Landlord receives during the initial Term an Offer (hereinafter defined) to lease such space. Notwithstanding any provision of the Lease to the contrary Tenant shall have no rights with respect to the Right of First Offer Space or any other rights of first offer or refusal, or first right to negotiate, or any other expansion rights whatsoever, except as expressly provided in this Section 23. Landlord represents and warrants to Tenant that, other than the renewal rights of France Telecom USA set forth in its lease with Landlord, no other tenant in the Building possesses any renewal rights, rights of first offer or refusal or other expansion rights with respect to the portion of the Right of First Offer Space which is located on the sixth (6^th) floor of the Building.

b. If, during the initial Term, Landlord receives a bona fide offer from a prospective tenant which is not related to Landlord (a “Prospective Tenant”) to lease all or any portion of the Right of First Offer Space (an “Offer”), the financial terms of which Landlord is prepared to accept, Landlord shall notify Tenant in writing of such Offer (the “ROFO Notice”), and Landlord shall set forth in the ROFO Notice: (i) a description of the portion of the Right of First Offer Space that is subject to the Offer (the “Available Space”), (ii) the base rent, tenant concessions and other terms and conditions pursuant to which Landlord would agree to lease the Available Space to Tenant (which terms need not be those contained in the Offer), and (iii) the date on which Landlord anticipates that the Available Space would become available for lease by Tenant (the “ROFO Availability Date”). Provided that (A) no Event of Default then exists under the Lease; (B) Tenant has not assigned the Lease, or sublet thirty-five percent (35%) or more of the Premises (other than to an Affiliate of Tenant); (C) not less than thirty-six (36) months remain in the Term as of the ROFO Availability Date; and (D) Tenant notifies Landlord, in writing, within ten (10) business days after Tenant receives the ROFO Notice, time being of the essence, of Tenant’s irrevocable election to lease all (but not less than all) of the Available Space described in the ROFO Notice on the terms and conditions set forth in the ROFO Notice (the “ROFO Tenant Election Notice”), Tenant shall have the right to lease all, but not less than all, of the Available Space described in the ROFO Notice on the terms and conditions set forth in the ROFO Notice.

c. In the event that Tenant timely delivers a ROFO Tenant Election Notice to Landlord, Landlord shall prepare an amendment modifying the Lease to incorporate the Available Space (the “ROFO Amendment”), which amendment shall accurately set forth, among other things: (i) the amount of Annual Base Rent for the Available Space (based on the per rentable square foot rental rate set forth in the ROFO Notice); (ii) the adjustments to Tenant’s obligation to pay Additional Rent caused by the addition of the Available Space; and (iii) any other term and condition applicable to the Available Space and mutually agreed to by and between Landlord and Tenant. The term of the demise of the Available Space (the “Right of First Offer Space Term”) shall commence on the date on which Landlord delivers such Available Space to Tenant (the “ROFO Space Commencement Date”), at which time all of Tenant’s obligations with respect to the Available Space shall commence, including the obligation to pay Annual Base Rent. In all instances, the Right of First Offer Space Term shall be coterminous with the Term of this Lease.

d. In the event that Landlord and Tenant enter in a ROFO Amendment, and Landlord is unable to deliver to Tenant possession of the Available Space demised thereunder on the ROFO Availability Date in vacant, broom-clean condition for any reason whatsoever, including without limitation the failure of an existing tenant to vacate such space, Landlord shall not be liable or responsible for any claims, damages or liabilities in connection therewith or by reason thereof/provided that (i) Landlord shall use reasonable efforts to obtain possession of such space (which reasonable efforts shall include the commencement of eviction proceedings) and deliver same to Tenant as soon as reasonably practicable thereafter; and (ii) rent with respect to the Available Space shall xxxxx until Landlord delivers the Available Space to Tenant. In the event that Landlord is unable to deliver the Available Space to Tenant by the date which is one hundred twenty (120) days after the ROFO Availability Date, subject to a day-for- day extension for matters of Force Majeure (the “Available Space Outside Delivery Date”), Tenant shall have the right, but not the obligation, to terminate the applicable ROFO Amendment upon ten (10) business days prior written notice to Landlord, in which event the applicable ROFO Amendment shall be null and void and of no further force or effect; provided that if Landlord delivers the Available Space to Tenant during such ten (10) business day period, the applicable ROFO Amendment shall not terminate and shall continue in full force and effect in accordance with its terms.

e. In the event Tenant fails timely to deliver a ROFO Tenant Election Notice to Landlord or, having done so, Tenant fails to execute the ROFO Amendment tendered by Landlord within ten (10) business days after Landlord tenders such amendment to Tenant: (i) Landlord may lease the Available Space (or any portion thereof) described in the ROFO Notice to any person or entity of Landlord’s choice, on whatever terms and conditions are selected by Landlord in its sole discretion; and (ii) this Section 23 shall terminate automatically, and Tenant shall have no further right to lease any Right of First Offer Space.

24. USA PATRIOT ACT AND ANTI-TERRORISM LAWS.

a. Landlord and Tenant each represents and warrants to, and covenants with, the other party that neither it, nor any of its respective constituent owners or affiliates currently are, or shall be at any time during the Term hereof, in violation of any laws relating to terrorism or money laundering (collectively, the “Anti-Terrorism Laws”), including without limitation Executive Order No. 13224 on Terrorist Financing, effective September 24, 2001 and relating to Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism (the “Executive Order”) and/or the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (Public Law 107-56) (the “USA Patriot Act”).

j. Landlord shall not be liable to Tenant for any damage caused by other tenants or persons in the Building or caused by operations of others in the construction of any private, public or quasi-public work.

k. If in this Lease it is provided that Landlord’s consent or approval as to any matter will not be unreasonably withheld or delayed, and it is established by a court or body having final jurisdiction thereover that Landlord has been unreasonable, the sole effect of such finding shall be that Landlord shall be deemed to have given its consent or approval, but Landlord shall not be liable to Tenant in any respect for money damages or expenses incurred by Tenant by reason of Landlord having withheld its consent. Nothing contained in this paragraph shall be deemed to limit Landlord’s right to give or withhold consent unless such limitation is expressly contained in the paragraph to which such consent pertains.

m. This Lease and the Exhibits hereto constitute the entire agreement between the parties, and supersedes any prior agreements or understandings between them.

p. Tenant (and any guarantor of this Lease), within fifteen (15) business days after Landlord delivers to Tenant (or such guarantor) written request therefor (“Landlord’s Financial Statement Request”), will provide Landlord with a copy of its most recent financial statements, consisting of a Balance Sheet, Earnings Statement, Statement of Changes in Financial Position, Statement of Changes in Owner’s Equity, and related footnotes, prepared in accordance with generally accepted accounting principles.

q. It is generally understood that mold spores are present essentially everywhere and that mold can grow in most any moist location. Emphasis is properly placed on prevention of moisture and on good housekeeping and ventilation practices. Tenant acknowledges the necessity of housekeeping, ventilation, and moisture control (especially in kitchens, janitor’s closets, bathrooms, break rooms and around outside walls) for mold prevention. Tenant represents that they have first inspected the aforementioned Premises and certifies that they have not observed mold, mildew or moisture within the Premises. Tenant agrees to immediately notify Landlord if they observe mold/mildew and/or moisture conditions (from any source, including leaks), and allow Landlord to evaluate and make recommendations and/or take appropriate corrective action. Except in the event of the negligence or willful misconduct of Landlord, its agents or employees, Tenant releases Landlord from any liability for any personal injury or damages to property caused by or associated with moisture or the growth of or occurrence of mold or mildew on the Premises. In addition, execution of this Lease constitutes acknowledgement by Tenant that control of moisture and mold prevention are integral to its obligations under this Lease.
