2.3 Improvements.

2.3.1 Landlord shall deliver the Premises to Tenant on the Tender Date in a vacant, clean condition with all physical injury or damage to the Premises (exclusive of normal wear and tear or damage to carpeting or cosmetic elements of the Premises) repaired and all property from previous occupants removed (unless otherwise approved in advance by Tenant), without (a) any obligation on Landlord’s part to undertake any improvements or alterations therein; or (b) any representations or warranties regarding the condition thereof. Notwithstanding the foregoing, Tenant shall, at Tenant’s sole cost and expense, subject to application of the Tenant Improvement Allowance, construct in the Premises the Tenant Improvements described in the Work Agreement in accordance with the terms 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 date of execution of this Lease, 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, which approval shall not be unreasonably withheld, conditioned or

delayed, except to the extent that any component of the Tenant Improvements is structural in nature or affects, or involves a change that materially affects the base Building or any of the base Building systems (including without limitation the plumbing, electric, HVAC, mechanical or life safety systems) therein, which Tenant Improvements shall be approved or rejected by Landlord in its sole discretion. The Tenant Improvements shall comply with all applicable building codes, laws and regulations (including, without limitation, Access Laws), 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.

2.3.2 The cost of all design, architectural and engineering work, construction costs, construction supervision, contractor’s 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 Tenant Improvement Allowance as more fully set forth in the Work Agreement.

Tenant shall use commercially reasonable efforts to obtain and maintain LEED for Commercial Interiors certification with respect to the Tenant Improvements, and Tenant shall register the Premises with the U.S. Green Building Council prior to completion of the Contract Documents (as defined in the Work Agreement).

2.4 Tender Date. Provided Tenant has delivered to Landlord evidence satisfactory to Landlord that all insurance required to be carried by Tenant and its contractor hereunder is effective, Tenant shall have access to the Premises immediately upon the occurrence of the Tender Date; provided, however, Tenant shall not be entitled to make any alterations or improvements to the Premises until the Tenant’s Plans (as defined in the Work Agreement) have been finally approved by Landlord in accordance with the terms of the Work Agreement. Except for purposes of constructing the Tenant Improvements in accordance with terms of the Work Agreement, Tenant shall not be permitted to occupy the Premises for purposes of conducting its business therein or for any other purpose, unless and until Tenant delivers to Landlord a certificate of occupancy which shall be obtained by Tenant at Tenant’s sole cost and expense. If Landlord notifies Tenant that the Premises are otherwise available for Tenant to take possession thereof, but Tenant is not permitted to take possession of the Premises because Tenant has failed to deliver to Landlord evidence reasonably satisfactory to Landlord that all insurance required hereunder to be carried by Tenant and its contractor is effective, then (a) Landlord shall be deemed to have tendered possession of the Premises to Tenant, (b) neither the Commencement Date nor the Rent Commencement Date shall be delayed as a result thereof, and (c) Tenant shall be entitled to access the Premises when such evidence of insurance has been delivered to Landlord. Between the Tender Date and the day immediately preceding the Rent

Commencement Date, all terms and provisions of this Lease shall be in full force and effect, except that Tenant shall not be obligated to pay any (i) Base Rent, or (ii) Additional Rent pursuant to paragraph 3.4, below.

Tenant shall have the right to terminate this Lease by delivering to Landlord, at any time between the Delay Termination Date and January 31, 2012, at least thirty (30) days prior written notice of such termination; provided, however, in the event the Tender Date occurs on or before the expiration of such thirty (30)-day period, such termination notice shall be deemed to be void and this Lease shall remain in full force and effect as though no termination notice had been delivered by Tenant. In the event the Tender Date does not occur on or before the expiration of such thirty (30)-day period, this Lease shall immediately terminate, and Landlord shall return the Prepaid Rent and the Security Deposit to Tenant. The Delay Termination Date shall be extended by one (1) day for each day that the Tender Date is delayed as a result of Force Majeure events described in paragraph 6.8 of this Lease.

2.5 Temporary Premises Prior to the Commencement Date.

Landlord shall deliver the Temporary Premises to Tenant on the Temporary Premises Commencement Date in its “as-is” condition without (a) any obligation on Landlord’s part to undertake or pay for any improvements or alterations therein; or (b) any representations or warranties regarding the condition thereof; provided, however, all Building systems servicing the Temporary Premises shall be in good working order on the Temporary Premises Commencement Date. In the event Landlord is unable to deliver possession of any portion of the Temporary Premises to Tenant on the Temporary Premises Commencement Date 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. In such event, Landlord shall use reasonable efforts to make the Temporary Premises available to Tenant as soon as reasonably practicable after the Temporary Premises Commencement Date.

2.5.2 During the Temporary Premises Term, Tenant shall not pay any Base Rent or Additional Rent pursuant to paragraphs 3.4.1, 3.4.2 and 3.4.7, below; provided, however Tenant acknowledges and agrees that Tenant shall be responsible for all other Additional Rent payable under the Lease with respect to the Temporary Premises, including without limitation, paragraph 3.4.8, below.

2.5.3 Except as otherwise set forth in this paragraph 2.5, the lease of the Temporary Premises shall be upon all the terms, conditions, covenants and agreements provided in this Lease. Without limiting the foregoing but in furtherance thereof, the parties acknowledge that, during the Temporary Premises Term, the term “Premises” as used in this Lease shall include the Temporary Premises. Notwithstanding the foregoing, Tenant shall not (a) assign its interest in the Temporary Premises or sublet all or any portion of the Temporary Premises, or (b) make any Tenant Alterations to the Temporary Premises or any part thereof.

2.5.4 Tenant shall vacate and surrender the Temporary Premises on or before the Temporary Premises Expiration Date, and from and after such date, Tenant shall have no further rights in or to the Temporary Premises. In the event that Tenant shall not immediately surrender the Temporary Premises on or before the Temporary Premises Expiration Date: (a) Tenant shall become a tenant at sufferance and such tenancy shall be subject to all the terms and conditions of paragraph 3.6 of this Lease; and (b) Tenant shall pay to Landlord, for each month (or portion thereof that Tenant remains in the Temporary Premises: (i) monthly Base Rent in the amount of One Hundred Nine Thousand Nine Hundred Twenty-Seven and 76/100 Dollars ($109,927.76); and (ii) all Additional Rent otherwise payable under paragraph 3.4, below, provided that (A) Tenant’s Pro Rata Share (Operating Costs) with respect to the Temporary Premises shall be 9.06%; and (B) Tenant’s Pro Rata Share (Property Taxes) with respect to the Temporary Premises shall be 8.53%. Tenant shall be solely responsible for any costs and expenses associated with moving from the Temporary Premises to the Premises.

2.5.5 Tenant hereby expressly acknowledges and agrees that (a) Tenant currently sub-subleases a portion of the Temporary Premises, containing approximately 3,500 rentable square feet on the sixth (6th) floor of the Building, pursuant to that certain Sub-Sublease Agreement dated as of January 26, 2010 (the “Performance Institute Sub-sublease”), by and between The Performance Institute, Inc, as sub-sublessor (the “Performance Institute”), and Tenant, as sub-sublessee; and (b) Performance Institute subleases a portion of the Temporary Premises, containing approximately 10,800 rentable square feet on the sixth (6th) floor of the Building, pursuant to that certain Sublease Agreement dated as of June 18, 2002, as amended, by and between Sapient Corporation, as sublessor (“Sapient”), and Performance Institute, as sublessee. Tenant further acknowledges that the term of the Performance Institute Sub-sublease expires on June 29, 2011. Tenant represents and warrants to Landlord that Tenant has sought and received Performance Institute’s and Sapient’s consent to Tenant’s occupancy of the Temporary Premises through and including June 30, 2011. Tenant shall indemnify and hold harmless Landlord from and against any cost, damage, claim, liability or expense (including reasonable attorneys’ fees) incurred by or claimed against Landlord, directly or indirectly, as a result of or in any way arising from any breach of the foregoing representation and warranty.

2.6 Lease Memorandum. Contemporaneously with the Commencement Date, Landlord shall prepare and submit to the Tenant a Lease Memorandum in the form of Exhibit D, completed in good faith by Landlord, and executed by Landlord. The information inserted on the Lease Memorandum shall be controlling and conclusive and shall prevail over any inconsistent provision in this Lease on (a) the mutual execution of the Lease Memorandum by Landlord and Tenant or (b) the lapse of fifteen (15) days following delivery of the Lease Memorandum to Tenant without Tenant delivering to Landlord a written objection to all or part of the information in the Lease Memorandum. If Tenant does object in good faith to any information set forth in the Lease Memorandum, it shall execute the Lease Memorandum subject to its specifically-stated, written objections. Tenant must explain the reasons for its objections in reasonable detail. That portion of the Lease Memorandum to which no objection was made shall be conclusive and controlling. Pending resolution of any dispute by agreement or a final determination by a court of competent jurisdiction in accordance with this Lease, Landlord’s

information as inserted in the Lease Memorandum shall be utilized subject to any later adjustment agreed or found to be appropriate. Tenant’s refusal or failure to execute a Lease Memorandum shall neither prevent nor delay the occurrence of the Commencement Date or the Rent Commencement Date. In no event shall the Lease Memorandum be recorded.

2.7 Use and Conduct of Business.

2.7.1 The Premises are to be used only for the Permitted Uses, and for no other business or purpose without the prior consent of Landlord. Landlord makes no representation or warranty as to the suitability of the Premises for Tenant’s intended use, provided that, to the best of Landlord’s actual knowledge, without independent inquiry or investigation, the Permitted Use is currently permitted in the Premises under Governmental Requirements applicable to the Building. Tenant shall, at its own cost and expense, obtain and maintain any and all licenses, permits, and approvals necessary or appropriate for its use, occupation and operation of the Premises for the Permitted Uses. Tenant’s inability to obtain or maintain any such license, permit or approval necessary or appropriate for its use, occupation or operation of the Premises shall not relieve it of its obligations under this Lease, including the obligation to pay Base Rent and Additional Rent.

2.7.2 No act shall be done in or about the Premises that is unlawful or that will increase the existing rate of insurance on any or all of the Land or Building. Tenant shall not commit or allow to be committed or exist: (a) any waste upon the Premises, (b) any public or private nuisance, or (c) any act or condition which disturbs the quiet enjoyment of any other tenant in the Building, violates any of Landlord’s contracts affecting any or all of the Land or Building, creates or contributes to any work stoppage, strike, picketing, labor disruption or dispute, interferes in any way with the business of Landlord or any other tenant in the Building or with the rights or privileges of any contractors, subcontractors, licensees, agents, concessionaires, subtenants, servants, employees, customers, guests, invitees or visitors or any other persons lawfully in and upon the Land or Building, or causes any impairment or reduction of the good will or reputation of the Land or Building.

2.7.3 Tenant shall not, without the prior consent of Landlord, use any apparatus, machinery, device or equipment in or about the Premises which will cause any substantial noise or vibration or any increase in the normal consumption level of electric power. If any of Tenant’s apparatus, machinery, devices or equipment should disturb the quiet enjoyment of any other tenant in the Building, then Tenant shall provide, at its sole cost and expense, adequate insulation or take other such action, including removing such apparatus, machinery, devices or equipment, as may be reasonably necessary to eliminate the disturbance.

2.8 Compliance with Governmental Requirements and Rules and Regulations. Tenant shall comply with all Governmental Requirements and Restrictions relating to its use, occupancy and operation of the Premises and shall observe such reasonable rules and regulations as may be adopted and published by Landlord from time to time for the safety, care and cleanliness of the Premises and the Building, and for the preservation of good order in the Building and for the administration and management of the Building. The current Rules and Regulations are attached to this Lease as Exhibit E.

2.9 Sustainable Building Operations.

2.9.1 The Building is or may become in the future certified under certain Green Agency Ratings or operated pursuant to Landlord’s sustainable building practices (as same may be in effect or reasonably modified by Landlord from time to time).

Commencing on the Rent Commencement Date and thereafter during the Lease Term, Tenant agrees to pay the monthly installments of Base Rent to Landlord, without demand and in advance, on or before the first day of each calendar month of the Lease Term. The monthly Base Rent installment for any partial month at the beginning or end of the Lease Term shall be prorated. Base Rent for any partial month at the beginning of the Lease Term shall be paid by Tenant on the Rent Commencement Date.

3.3 Lease Security Provisions.

3.3.1 As security for the full and faithful payment of all sums due under this Lease and the full and faithful performance of every covenant and condition of this Lease to be performed

by Tenant, within fifteen (15) Business Days after Tenant’s execution and delivery to Landlord of this Lease, Tenant shall deliver to Landlord a letter of credit in the amount of One Million Three Hundred Nineteen Thousand One Hundred Thirty-Three and 00/100 ($1,319,133.00) in favor of Landlord as a lease security deposit (“Lease Security Deposit”). The letter of credit initially delivered pursuant to this paragraph and all substitutions, replacements and renewals of it, must be a form substantially similar to the form set forth on Exhibit H and incorporated by reference herein. Tenant’s failure to deliver the Letter of Credit to Landlord within ten (10) days after Tenant’s execution and delivery to Landlord of this Lease shall constitute an Event of Default (hereinafter defined) under this Lease. As used herein, the term “Letter of Credit” shall mean and refer to a letter of credit which conforms to, and satisfied the requirements of, this subparagraph issued by a federally-insured banking institution reasonably acceptable to Landlord, having total assets of at least Ten Billion Dollars ($10,000,000,000.00) and/or a Standard & Poor’s commercial paper rating of at least A-1. Landlord hereby approves Silicon Valley Bank as the issuer of the Letter of Credit.

3.3.2 Landlord may draw on the Letter of Credit, in whole or in part at Landlord’s election, without advance notice to Tenant at any time or from time to time on or after (a) the occurrence of any Event of Default, (b) if Tenant, or anyone in possession of the Premises through Tenant, holds over, without Landlord’s written consent, after the expiration or earlier termination of this Lease, (c) Landlord is given notice by the issuer of the Letter of Credit that it is terminating the Letter of Credit, and Tenant fails to deliver to Landlord a replacement Letter of Credit at least thirty (30) days prior to such termination date, (d) the Letter of Credit expires on a specified date by its terms and is not renewed or replaced at least thirty (30) days in advance of its expiration date, (e) the then issuer of the Letter of Credit no longer has total assets of at least Ten Billion Dollars ($10,000,000,000) and a Standard & Poor’s commercial paper rating of at least A-1 (“Minimum Bank Threshold”), and Tenant does not replace the Letter of Credit with a Letter of Credit from a bank which complies with the Minimum Bank Threshold within fifteen (15) days of receipt of written notice from Landlord, or (f) to the extent permitted by law, in the event any bankruptcy, insolvency, reorganization or any other debtor creditor proceeding is instituted by or against Tenant.

3.3.3 Upon the occurrence of an Event of Default, Landlord may apply any applicable sum drawn on the Letter of Credit to amounts owing to Landlord under this Lease in such order and priority as Landlord elects in its absolute discretion. If any of the proceeds drawn under the Letter of Credit are not applied immediately to sums owing to Landlord under this Lease, Landlord may retain any such excess proceeds as a cash Lease Security Deposit for application, at Landlord’s election, to future sums owing to Landlord under this Lease, in such order and priority as Landlord elects in its absolute discretion. If Landlord applies any of the proceeds drawn on the Letter of Credit, Tenant shall, within fifteen (15) days after Landlord’s demand, restore the amount of the Letter of Credit drawn so that the Letter of Credit is restored to the original amount of the Letter of Credit, in which event Landlord shall return to Tenant any excess proceeds from the Letter of Credit, within thirty (30) days of such restoration. If Tenant does not restore the Letter of Credit to its original amount within the required time period, such non-restoration shall be considered an Event of Default.

3.3.4 Landlord’s draw and application of all or any portion of the proceeds of the Letter of Credit shall not impair any other rights or remedies provided under this Lease or under

applicable law and shall not be construed as a payment of liquidated damages. If Tenant shall have fully complied with all of the covenants and conditions of this Lease, the Letter of Credit shall be returned to Tenant or, if Landlord has drawn on the Letter of Credit, the remaining proceeds of the Letter of Credit which are in excess of sums due Landlord shall be repaid to Tenant, without interest, within thirty (30) Business Days after the expiration or termination of the Lease Term and delivery of possession of the Premises to Landlord in accordance with this Lease.

3.3.5 Upon any request by Landlord made during the Lease Term, Tenant shall at no expense to Tenant, cooperate in accomplishing any reasonable modification of the Letter of Credit requested by Landlord. If the Letter of Credit should be lost, mutilated, stolen or destroyed, Tenant shall cooperate in obtaining the issuance of a replacement at no expense to Tenant.

3.3.6 Tenant shall not assign or grant any security interest in the Letter of Credit and any attempt to do so shall be void and of no effect.

3.3.7 In the event of a sale or transfer of Landlord’s estate or interest in the Land and Building, Tenant shall have the right to transfer the Letter of Credit to the vendee or the transferee. Tenant shall pay any transfer fees charged by the issuing bank and Landlord shall thereafter be considered released by Tenant from all liability for the return of the Letter of Credit. Tenant shall look solely to the transferee for the return of the Letter of Credit and it is agreed that all of the foregoing shall apply to every transfer or assignment made of the Letter of Credit to a new transferee. Tenant shall cooperate in effecting such transfer.

3.3.8 Intentionally Deleted.

3.3.9 In the event of any rightful and permitted assignment of Tenant’s interest in this Lease, the Letter of Credit (or any other Lease Security Deposit) shall be deemed to be held by Landlord as a deposit made by the assignee, and Landlord shall have no further liability to the assignor with respect to the return of the same.

3.3.10 Notwithstanding anything to the contrary set forth in this paragraph 3.3, provided that the Reduction Requirements (hereinafter defined) have been satisfied by Tenant, then on each of the following dates (each, a “Reduction Date”). Tenant may notify Landlord in writing (the “Reduction Request”) and request that the Lease Security Deposit be reduced by the amount set forth below with respect to the applicable Reduction Date:


Reduction Date	Reduction Amount		Minimum L/C Amount
Last day of the twenty-fifth (25^th) full calendar month following the Rent Commencement Date	$	293,140.66	$	1,025,992.34
Last day of the thirty-seventh (37^th) full calendar month following the Rent Commencement Date	$	439,710.99	$	586,281.35
Last day of the forty-ninth (49^th) full calendar month following the Rent Commencement Date	$	293,140.66	$	293,140.69

Provided that the Reduction Requirements have been satisfied at the time Landlord receives a Reduction Request, Landlord shall instruct the bank in writing, within thirty (30) days after Landlord’s receipt of the Reduction Request, that the Letter of Credit may be reduced by the Reduction Amount, which reduction 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). Notwithstanding anything to the contrary contained in this paragraph 3.3, the Letter of Credit shall never be reduced under this paragraph 3.3.10 to an amount less than the Minimum L/C Amount set forth in the chart above with respect to the applicable Reduction Date. As used in this paragraph 3.3.10, the term “Reduction Requirements” shall mean the following requirements: (i) Tenant has not assigned its interest in this Lease or sublet more than twenty-five percent (25%) of the Premises, except to a Qualified Tenant Affiliate (hereinafter), (ii) no Event of Default then exists, (iii) there is not then occurring any event or occurrence which if not cured within the applicable time period set forth in this Lease would constitute an Event of Default, (iv) Tenant has not delivered a Termination Notice (hereinafter defined) pursuant to paragraph 6.20, and (v) Tenant has delivered to Landlord current financial statements (including a statement of operations and balance sheet and statement of cash flows) certified as accurate by a certified public accountant and prepared in conformance with generally accepted accounting principles, which financial statements demonstrate that Tenant maintains Ten Million Dollars ($10,000,000.00) in cash and cash equivalents.

3.4 Additional Rent. Definitions of certain terms used in this paragraph are set forth in the last subparagraph of this paragraph entitled “Additional Rent”. Tenant agrees to pay to Landlord additional rent as computed in this paragraph (individually and collectively the “Additional Rent”):

3.4.1 Estimated Operating Costs. Commencing on the first anniversary of the Commencement Date, Tenant shall pay to Landlord as Additional Rent one-twelfth (1/12) of the amount, if any, by which the Estimated Operating Costs Allocable to the Premises exceeds the Base Amount Allocable to the Premises. This sum shall be paid in advance on or before the first day of each calendar month of the Lease Term. Landlord shall furnish Tenant a written statement of Estimated Operating Costs Allocable to the Premises (in a form similar to that delivered by Landlord to Tenant prior to the Effective Date) in advance of the commencement of each Year. If such written statement is furnished after the commencement of the Year (or as to the first Year during the Lease Term, after the Commencement Date), within thirty (30) days of Tenant’s receipt of same, Tenant shall also make a retroactive lump-sum payment to Landlord equal to the monthly payment amount multiplied by the number of months during the Year (or as to the first Year during the Lease Term, after the Commencement Date) for which no payment was paid. Notwithstanding the foregoing, Landlord reserves the right, from time to time during each Year, to revise the Estimated Operating Costs Allocable to the Premises and upon notice to

Tenant of such revision, Tenant shall adjust its payment to Landlord under this subparagraph 3.4.1 accordingly. Notwithstanding the foregoing, in no event shall Tenant be obligated to pay for Controllable Expenses (as defined below) for any calendar year during the Lease Term to the extent that they have increased by more than six percent (6%) per annum, compounded annually on a cumulative basis during the Lease Term beginning with calendar year 2012. As used herein, “Controllable Expenses” means all categories of Operating Costs other than the following categories: (i) the costs of water, sewer, electricity, gas and other utilities serving the Building or the Land, (ii) Property Taxes (it being acknowledged by the parties that, within this Lease, “Property Taxes” are expressly excluded from the term “Operating Costs”), (iii) snow and ice removal, (iv) union labor costs, (v) cost of insurance, (vi) the removal or remediation of hazardous substances, (vii) cleaning costs, (viii) repairs and maintenance which is not undertaken pursuant to an annual service contract, (ix) Permitted Capital Expenditures, and (x) the cost of obtaining permits and other governmental approvals.

3.4.2 Actual Costs. Promptly after the close of each Year (provided that Landlord agrees to use commercially reasonable efforts to deliver same prior to April 1st of each Year), Landlord shall deliver to Tenant a written statement setting forth the Operating Costs Allocable to the Premises during the preceding Year. Landlord agrees that the written statements for the Base Year and each future Year shall contain the same general expense categories. If such Operating Costs Allocable to the Premises for any Year exceed the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph 3.4.1 for such Year, Tenant shall pay the amount of such excess to Landlord within thirty (30) Business Days after receipt of such statement by Tenant. If such statement shows the Operating Costs Allocable to the Premises to be less than the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph 3.4.1, then the amount of such overpayment shall be paid by Landlord to Tenant within thirty (30) days following the date of such statement or, at Tenant’s option, shall be credited towards the installment(s) of Base Rent next coming due from Tenant.

3.4.3 Determination. The determination of Operating Costs Allocable to the Premises shall be made by Landlord using generally accepted accounting principles.

3.4.4 Operating Cost Audit. Landlord shall maintain records concerning estimated and actual Operating Costs Allocable to the Premises for no less than two (2) years following the period covered by the statement or statements furnished Tenant, after which time Landlord may dispose of such records. Provided that there exists no uncured Event of Default under this Lease, Tenant may, at Tenant’s sole cost and expense, cause a Qualified Person (defined below) to inspect Landlord’s records. Such inspection, if any, shall be conducted no more than once each Year, during Normal Business Hours (hereinafter defined) within one hundred twenty (120) calendar days after receipt of Landlord’s written statement of Operating Costs Allocable to the Premises solely for the previous Year, upon first furnishing Landlord at least ten (10) Business Days prior written notice. As a condition precedent to undertaking such inspection: (a) Tenant and the Qualified Person shall execute a Confidentiality Agreement prepared by Landlord and reasonably acceptable to Tenant; and (b) Tenant shall pay all Operating Costs which Landlord claims are owing for the Year in question. Any errors disclosed by the review shall be promptly corrected by Landlord; provided, however, that if Landlord disagrees with any such claimed errors, Landlord shall have the right to cause another review to be made by an auditor of

Landlord’s choice. In the event the results of the review of records (taking into account, if applicable, the results of any additional review caused by Landlord) reveal that Tenant has overpaid obligations for a preceding period, the amount of such overpayment shall be credited against Tenant’s subsequent installment of Base Rent, Additional Rent or other payments due to Landlord under the Lease. In the event that such results show that Tenant has underpaid its obligations for a preceding period, the amount of such underpayment shall be paid by Tenant to Landlord within thirty (30) days of receipt of an invoice from Landlord. If the actual Operating Costs Allocable to the Premises for any given Year were improperly computed and if the actual Operating Costs Allocable to the Premises are overstated by more than 5% in the aggregate, Landlord shall reimburse Tenant for the reasonable cost of its audit within thirty (30) days of receipt of an invoice (and supporting documentation) from Tenant.

3.4.5 End of Lease Term. If the Lease Term shall terminate on a day other than the last day of a Year: (a) Landlord shall estimate the Operating Costs and Property Taxes Allocable to the Premises for such Year predicated on the most recent reliable information available to Landlord; (b) the amount determined under clause (a) of this sentence shall be prorated by multiplying such amount by a fraction, the numerator of which is the number of days within the Lease Term in such Year and the denominator of which is 365; (c) the Operating Costs Base Amount Allocable to the Premises shall be prorated in the manner described in clause (b); (d) the clause (c) amount (i.e., the prorated Base Amount Allocable to the Premises) shall be deducted from the clause (b) amount (i.e., the prorated Operating Costs Allocable to the Premises); (e) if the clause (d) amount exceeds the Estimated Operating Costs Allocable to the Premises paid by Tenant for the last Year in the Lease Term, then Tenant shall pay the excess to Landlord within ten (10) Business Days after Landlord’s delivery to Tenant of a statement for such excess; and (f) if the Estimated Operating Costs Allocable to the Premises paid by Tenant for the last Year in the Lease Term exceeds the clause (d) amount, then provided that Tenant is not then in default of any of its obligations under this Lease, Landlord shall refund to Tenant the excess within the ten (10) Business Day period described in clause (e) (provided, however, that Landlord shall have the right to retain only so much of such excess as is necessary to cure any such default). Landlord’s and Tenant’s obligations under this paragraph shall survive the expiration or other termination of this Lease.

3.4.6 Definitions. Each underlined term in this subparagraph shall have the meaning set forth next to that underlined term:

If at any time during any Year, any part of the Building is leased to a tenant (hereinafter referred to as a “Special Tenant”) which provides its own utilities, cleaning or janitorial services or other services or is not otherwise required to pay a share of Operating Costs in accordance with the methodology set forth in this paragraph 3.4, and Landlord does not incur the cost of such services, Operating Costs for such Year shall be increased by the additional costs for utilities, 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 utilities, cleaning and janitorial services and such other services for the space occupied by the Special Tenant.

3.4.10 Payments Deemed Additional Rent. Any sums payable under this Lease pursuant to this paragraph or otherwise shall be Additional Rent and, subject to applicable notice and cure periods, in the event of nonpayment of such sums, Landlord shall have the same rights and remedies with respect to such nonpayment as it has with respect to nonpayment of the Base Rent due under this Lease.

Tenant shall contract directly and pay for all water, gas, heat, light, power, Telecommunication Services, sewer, sprinkler charges and other utilities used on or from the Premises together with any taxes, penalties, surcharges or similar charges relating to such utilities. If any such service is not separately metered to the Premises or is not otherwise separately accounted for and billed to Tenant, the cost therefor shall be an Operating Cost under this Lease.

3.5.2 Tenant acknowledges that space on the Building rooftop and in the Building risers, equipment rooms and equipment closets is limited. Unless otherwise required by law, neither Tenant, nor a provider of Telecommunication Services to Tenant, in the future shall be entitled to locate or install Telecommunication Facilities in, on or about the Building without (a) first obtaining Landlord’s advance, written consent, which consent shall not be unreasonably withheld, delayed or conditioned, and (b) the advance execution by Landlord and Tenant of a satisfactory agreement granting a license to Tenant for such purposes and setting forth the scope, the additional rent, if any, royalties and the other terms and conditions of that license, and (c) Tenant negotiating and obtaining the right, if any is required, to bring such Telecommunication Facilities across public or private property to an approved entry point to the Building. The agreement referred to in clause (b) of the previous sentence shall be incorporated in and become

part of this Lease. Any future application by Tenant for permission to locate or install Telecommunication Facilities shall (1) be in such form and shall be accompanied by such supporting information as the Landlord may require, (2) be subject to such procedures, regulations and controls as the Landlord may specify and (3) be accompanied by such payment as the Landlord may reasonably request to reimburse Landlord for its costs of evaluating and processing the application and in negotiating and preparing the agreement described earlier in this subparagraph.

3.5.3 Landlord shall in no case be liable or in any way be responsible for damages or loss to Tenant arising from the failure of, diminution of or interruption in electrical power, natural gas, fuel, Telecommunication Services, sewer, water, or garbage collection services, other utility service or building service of any kind to the Premises, unless such interruption in, deprivation of or reduction of any such service was caused by the gross negligence or willful misconduct of Landlord, its agents or contractors or by a failure in facilities, equipment or systems in the Landlord’s ownership. To the extent that Landlord bears any responsibility for any such interruption, deprivation or reduction in utility or building services to the Premises (due to Landlord’s having caused same by its negligence or willful misconduct), Landlord’s sole responsibility and Tenant’s sole remedy shall be limited to an equitable adjustment of Base Rent in proportion to the ratio that the rentable square footage of the Material Portion (hereinafter defined) of the Premises which Tenant does not occupy bears to the entire rentable square footage of the Premises for the period of interruption, depreciation or reduction, retroactive to the day on which Tenant delivers written notice to Landlord (a) describing such interruption, deprivation or reduction, and (b) stating that Tenant is being deprived of the reasonable use of, and has ceased to use or occupy, a Material Portion of the Premises (which portion of the Premises shall be specified by Tenant in such notice), and ending on the date such interruption, deprivation or reduction which is Landlord’s responsibility is no longer causing Tenant to be deprived of the use of a Material Portion of the Premises. As used herein, the term “Material Portion” means twenty percent (20%) or more of the rentable area of the Premises. Except in the case of an emergency or with respect to an interruption which is not within Landlord’s control or about which Landlord had no prior knowledge, Landlord will give Tenant at least five (5) Business Days’ prior notice if Landlord intends to cause the interruption of any services required to be furnished by the Landlord.

3.6 Holdover. If Tenant shall not immediately surrender the Premises at the expiration of the Lease Term or earlier termination of the Lease, then Tenant shall, by virtue of the provisions of this paragraph 3.6, 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 installment of 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 Lease 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. Landlord shall have all the rights and remedies provided for by law and this Lease, including the right to recover damages (including consequential damages) suffered by Landlord in the event of Tenant’s holdover in the Premises; provided, however, Tenant shall not be liable for any consequential damages in the event Tenant vacates the Premises in accordance with the terms of this Lease within sixty (60) days following the termination of this Lease

3.7 Late Charge: If Tenant fails to make any payment of Base Rent, Additional Rent or other amount when due under this Lease, and such failure continues for five (5) days following written notice thereof (provided that no notice shall be required with respect to the second (2nd) and each subsequent late payment of Base Rent or Additional Rent during any twelve (12) month period during the Lease Term), a late charge is immediately due and payable by Tenant equal to five percent (5%) of the amount of any such payment; provided that with respect to the first failure by Tenant during any twelve (12) month period within the Lease Term to pay Base Rent, Additional Rent or other charges when due, no late charge shall be assessed unless Landlord has notified Tenant in writing of such failure and Tenant fails to tender such payment to Landlord within five (5) Business Days after Landlord’s delivery of written notice to Tenant. Landlord and Tenant agree that this charge compensates Landlord for the administrative costs caused by the delinquency. The parties agree that Landlord’s damage would be difficult to compute and the amount stated in this paragraph 3.7 represents a reasonable estimate of such damage. Assessment or payment of the late charge contemplated in this paragraph 3.7 shall not excuse or cure any Event of Default or breach by Tenant under this Lease or impair any other right or remedy provided under this Lease or under law.

3.8 Default Rate. Any Base Rent, Additional Rent or other sum payable under this Lease which is not paid when due shall bear interest at a rate equal to the lesser of: (a) the published prime or reference rate of PNC Bank N.A., or such other national banking institution designated by Landlord if such bank ceases to publish such rate (the “Prime Rate”), then in effect, plus two (2) percentage points, or (b) the maximum rate of interest per annum permitted by applicable law (the “Default Rate”), but the payment of such interest shall not excuse or cure any Event of Default or breach by Tenant under this Lease or impair any other right or remedy provided under this Lease or under law.

SECTION 4: MANAGEMENT AND LEASING PROVISIONS

4.1 Maintenance and Repair by Landlord. Subject to the terms of paragraph 4.9(captioned “Damage or Destruction”) and paragraph 4.10 (captioned “Condemnation”) of this Lease, Landlord shall maintain the public, structural and common areas of the Building, including but not limited to the external and structural components of the Building, the exterior glass, the Garage and the base Building HVAC system, mechanical system, electrical system, and plumbing system in reasonably good order and condition subject to reasonable wear and tear throughout the Lease Term in a manner consistent with the standard of maintenance employed by the owners of office buildings in Arlington, Virginia of an age, size and condition comparable to the Building. Landlord shall make such repairs thereto as become necessary after obtaining

actual knowledge of the need for such repairs. Landlord shall replace Building standard light bulbs and ballasts (and the replacement cost of same shall be an Operating Cost), and Tenant shall replace any specialty light bulbs and ballasts at its sole cost and expense. All maintenance and repair costs shall be included in Operating Costs, except for damage occasioned by the act or omission of Tenant or Tenant’s Agents which shall be paid for entirely by Tenant upon demand by Landlord (subject to Landlord’s receipt of insurance proceeds, if any). In the event any or all of the Building becomes in need of maintenance or repair which Landlord is required to make under this Lease, Tenant shall promptly give written notice to Landlord, and Landlord shall be obligated to commence such maintenance or repairs within a reasonable time after Landlord’s receipt of such notice.

4.2 Maintenance and Repair by Tenant. Except as is expressly set forth as Landlord’s responsibility pursuant to paragraph 4.1 of this Lease (captioned “Maintenance and Repair by Landlord”), and except for the janitorial services to be provided by Landlord in accordance with Exhibit G. Tenant shall at Tenant’s sole cost and expense keep, clean and maintain the Premises in good condition and repair, ordinary wear and tear excepted, including interior painting, cleaning of the interior side of all exterior glass, plumbing and utility, and installations, carpets and floor coverings, all interior wall surfaces and coverings (including tile and paneling), interior window replacement, exterior and interior doors, roof penetrations and membranes in connection with any Tenant requested installations on the roof, non-Building standard light bulb and ballast replacement (which lighting purchase must comply with Landlord’s sustainability practices and shall be reported to Landlord in a format suitable to Landlord) and interior preventative maintenance. Tenant shall use commercially reasonable efforts to ensure that all maintenance and repairs made by Tenant comply with Landlord’s sustainability practices and any applicable Green Agency Rating (as the same may change from time to time). If Tenant fails to maintain or repair the Premises in accordance with this paragraph 4.2, then Landlord may, but shall not be required to, enter the Premises upon two (2) Business Days’ prior written notice to Tenant (or immediately without any notice in the case of an emergency) to perform such reasonable maintenance or repair at Tenant’s sole cost and expense. Tenant shall pay to Landlord the cost of such maintenance or repair plus a fifteen percent (15%) administration fee within ten (10) Business Days of written demand from Landlord.

4.3 Common Areas/Security.

4.3.1 The common areas of the Building shall be subject to Landlord’s sole management and control; provided that, Landlord shall not unreasonably interfere with Tenant’s access to the Premises (except to the extent necessary in an emergency situation). Without limiting the generality of the immediately preceding sentence, Landlord reserves the exclusive right as it deems necessary or desirable to install, construct, remove, maintain and operate lighting systems, facilities, improvements, equipment, Telecommunication Facilities and signs on, in or to all parts of the common areas; change the number, size, height, layout, or locations of walks, driveways and truckways or parking areas now or later forming a part of the Land or Building; make alterations or additions to the Building or common area; close temporarily all or any portion of the common areas to make repairs, changes or to avoid public dedication, provided that if such closure prevents Tenant from gaining access to the Premises, Landlord shall provide alternative access to the Premises for Tenant that is reasonable in location and distance from the current access; grant easements to which the Land will be subject; replat, subdivide, or

make other changes to the Land; place or relocate or cause to be placed or located utility lines and Telecommunication Facilities through, over or under the Land and Building; and use or permit the use of all or any portion of the roof of the Building; provided, however, in no event shall Landlord’s exercise of the foregoing rights (i) unreasonably interfere for a period longer than two (2) Business Days with Tenant’s use of the Premises, or (ii) preclude Tenant from gaining reasonable access to the Premises. Landlord reserves the right to relocate parking areas and driveways and to build additional improvements in the Garage and other common areas of the Land so long as Tenant’s Parking Ratio is maintained and provided that: (A) the relocated areas in which Tenant is permitted to park are a reasonable distance from Tenant’s then-current parking areas; and (B) the relocated driveways are a reasonable distance from the then-current driveways.

4.3.2 Landlord has no duty or obligation to provide any security services in, on or around the Premises, Land or Building; provided however that Landlord agrees to maintain (the cost of which maintenance shall constitute an Operating Cost of the Building), the existing “Datawatch” perimeter vendor card access system at the exterior entry doors to the Building, all exterior ingress and egress points (including the loading dock and Garage) to the Building, and in all Building elevators, for access during non-Building Standard Hours. Landlord shall provide to Tenant at no charge up to 25 key cards or other system access fobs. Any replacement cards shall be at Tenant’s sole cost and expense based on Landlord’s actual cost. Landlord reserves the right, in its sole discretion, to reasonably modify or supplement the access control system, or to substitute another vendor’s access control system (which vendor is selected by Landlord in its sole discretion) for use at the Building. The costs of any such additional, substitute or modified access control system shall be includable in Operating Costs. Tenant recognizes that access control services, if any, provided by Landlord (or to be installed and maintained by Landlord pursuant to this paragraph 4.3.2) will be for the sole benefit of Landlord and the protection of Landlord’s property and under no circumstances shall Landlord be responsible for the provision of security or other protection for Tenant or Tenant’s Agents or property in, on or about the Premises, Land or Building. Landlord shall not be liable for any injury or death to persons arising out of the provision, or failure to provide, access control services or security services at the Building, unless such injury or death was caused solely by Landlord’s gross negligence. Subject to Landlord’s prior written approval of the plans and specifications therefor, which shall not be unreasonably withheld, conditioned or delayed, Tenant may, at its sole cost and expense, install, establish and maintain an access control system or services within the Premises; provided that, Tenant’s access control system or services (including any apparatus, facilities, equipment or people utilized in connection with the provision of such access control services) comply with the Governmental Requirements and shall not cause the Building to be out of compliance with the Governmental Requirements. Notwithstanding the foregoing, any such security services installed, established or maintained by Tenant must not affect or impact any portion of the Building or the Land other than the Premises and shall not in any way limit or interfere with Landlord’s ability to exercise its rights as provided in paragraph 4.8 of this Lease (captioned “Access”). Tenant’s rights under this subparagraph 4.3.2 are subject to all the obligations, limitations and requirements as set forth in paragraph 4.4 of this Lease (captioned “Tenant Alterations”) and paragraph 4.5 of this Lease (captioned “Tenant’s Work Performance”).

4.4 Tenant Alterations. Tenant shall not make any alterations, additions or improvements in or to the Premises, or make changes to locks on doors, or add, disturb or in any way change

any floor covering, wall covering, fixtures, plumbing, wiring or Telecommunication Facilities (individually and collectively, “Tenant Alterations”) without the prior written consent of Landlord, which shall not be unreasonably withheld, conditioned or delayed, except to the extent that any proposed Tenant Alteration is structural in nature or affects, or involves a material change to the base Building or any of the base Building systems (including without limitation the plumbing, electric, HVAC, mechanical or life safety system) therein, which Tenant Alterations shall be approved or rejected by Landlord in its sole discretion. Tenant shall deliver to Landlord full and complete plans and specifications for any proposed Tenant Alterations, except for Cosmetic Alterations (hereinafter defined). All such plans and specifications shall be subject to Landlord’s consent, not to be unreasonably withheld, conditioned or delayed, except to the extent any proposed Tenant Alteration described therein is structural in nature or affects, or involves a material change to the base Building or any of the base Building systems (including without limitation the plumbing, electric, HVAC, mechanical or life safety system) therein, which Tenant Alterations shall be approved or rejected by Landlord in its sole discretion. All Tenant Alterations shall be performed at Tenant’s sole expense. Tenant shall use commercially reasonable efforts to ensure that any and all Tenant Alterations that affect at least fifty percent (50%) of the Premises will be performed in accordance with Landlord’s sustainability practices (as same may be amended or supplemented from time to time) and any Green Agency Ratings (as the same may change from time to time). Tenant further agrees to have all plans, material procurement, demolition, construction and waste management procedures reviewed by a qualified professional to ensure they are in full conformance to Landlord’s sustainability practices, as aforesaid, and Tenant agrees to use commercially reasonable efforts to seek and maintain LEED for Commercial Interiors certification for all Tenant Alterations that involve at least fifty percent (50%) of the Premises. Tenant shall pay to Landlord all reasonable, actual and documented costs incurred by Landlord for any out-of-pocket architectural, engineering and supervisory services in connection with any Tenant Alterations, including, without limitation, Landlord’s review of the plans and specifications therefor, in an amount not to exceed $10,000.00; provided, however, Tenant shall not be responsible for any architectural engineering or supervisory services or costs incurred by Landlord to ensure that the Tenant Alterations meet Landlord’s sustainability practices. The cost of Landlord’s internal review of the plans for the Tenant Alterations shall be borne by the Landlord. Landlord may require Tenant (if Landlord has elected to require Tenant to perform the Tenant Alterations), at Tenant’s sole cost and expense, to obtain and provide Landlord with proof of insurance coverage. Notwithstanding anything to the contrary in this paragraph 4.4, Tenant shall have the right, after giving fifteen (15) days’ prior written notice to Landlord (which notice shall include in reasonable detail a description of the Cosmetic Alterations which Tenant proposes to undertake) , but without the necessity of obtaining Landlord’s consent, to undertake Cosmetic Alterations. As used herein, the term “Cosmetic Alterations” means those Tenant Alterations which are cosmetic in nature, do not require a building permit to undertake, are not visible from outside the Premises and which cost in the aggregate less than One Hundred Thousand Dollars ($100,000.00) to undertake. All paint and carpet colors utilized by Tenant in undertaking Cosmetic Alterations shall be Building standard colors, unless otherwise approved in advance by Landlord. Should Tenant make any alterations without Landlord’s prior written consent, or without satisfaction of any conditions established by Landlord, Landlord shall have the right, in addition to and without limitation of any right or remedy Landlord may have under this Lease, at law or in equity, to require Tenant to remove some or all of Tenant Alterations, or at Landlord’s election, Landlord

may remove such Tenant Alterations and restore the Premises at Tenant’s expense. Nothing contained in this paragraph or the paragraph captioned “Tenant’s Work Performance” shall be deemed a waiver of the provisions of the paragraph captioned “Mechanic’s Liens”.

4.5 Tenant’s Work Performance.

4.5.1 If Tenant performs Tenant Alterations which cost more than $100,000.00 in the aggregate and which require a building permit to undertake, Landlord may, in its absolute discretion, require that Tenant provide a payment and performance bond to cover the entire work to be performed, which bond must be in form, amount and by a company reasonably acceptable to Landlord. Any Tenant Improvements or Tenant Alterations (including any Telecommunications Facilities and/or any telecommunications cabling or wiring, and any furniture installation), and any other work to be performed by Tenant shall be performed by contractors employed by Tenant under one or more construction contracts, in form and content approved in advance in writing by Landlord, such approval not to be unreasonably withheld, conditioned or delayed. With respect to any construction contracts for work to be performed on behalf of Tenant, such contracts shall include a requirement that the prime contractor and the respective subcontractors of any tier performing the Tenant Alterations: (a) be parties to, and bound by, a collective bargaining agreement with a labor organization affiliated with the Building and Construction Trades Council of the AFL-CIO or with an independent, nationally recognized labor organization or one of its affiliated local organizations applicable to the geographic area in which the Building is located and to the trade or trades in which the work under the contract is to be performed and (b) employ only members of such labor organizations to perform work within their respective jurisdictions (the “Contractor Requirements”). Tenant’s contractors, workers and suppliers shall work in harmony with and not interfere with workers or contractors of Landlord or other tenants of Landlord. If Tenant’s contractors, workers or suppliers do, in the opinion of Landlord, cause such disharmony or interference, Landlord’s consent to the continuation of such work may be withdrawn upon written notice to Tenant. All Tenant Alterations shall be (1) completed in accordance with the plans and specifications approved by Landlord; (2) completed in accordance with all Governmental Requirements (including without limitation all Access Laws); (3) carried out promptly in a good and workmanlike manner; (4) free of defect in materials and workmanship. Tenant shall pay for all damage to the Premises, Building and Land caused by Tenant or Tenant’s Agents; and (5) performed in strict conformity with valid building permits and other authorizations from appropriate governmental agencies, when required, which shall be obtained by Tenant, at Tenant’s expense.

4.5.2 In addition to the requirements set forth in subparagraph 4.5.1 above, Tenant shall use commercially reasonable efforts to contract for services to be performed in or about the Premises with Responsible Contractors (hereinafter defined). As used in this Lease, the term “Responsible Contractor” shall mean a contractor or subcontractor who pays workers a fair wage and Fair Benefits (hereinafter defined) as evidenced by payroll and employee records and who complies with the service-disabled veteran business (“SDV/BE”) policy. As used in this Lease, the term “Fair Benefits” shall mean employer-paid family health care coverage, pension benefits, and apprenticeship programs.

4.6 Surrender of Possession. Subject to the last subparagraph of the paragraph captioned “Insurance”, Tenant shall, at the expiration or earlier termination of this Lease, surrender and deliver the Premises to Landlord in as good condition as when received by Tenant from Landlord or as later improved, excepting reasonable use and wear, casualty, the responsibility for the repair of which is Landlord’s under this Lease, and condemnation damage, and free from all tenancies or occupancies by any person.

4.7 Removal of Property. Upon expiration or earlier termination of this Lease, Tenant may remove its personal property, office supplies and office furniture and equipment if (a) such items are readily moveable and are not attached to the Premises; (b) such removal is completed prior to the expiration or earlier termination of this Lease; (c) no Event of Default exists at the time of such removal; and (d) Tenant immediately repairs all damage caused by or resulting from such removal. All other property in the Premises and any Tenant Alterations (including, wall-to-wall carpeting, paneling, wall covering, lighting fixtures and apparatus or wiring for Telecommunication Facilities or any other article affixed to the floor, walls, ceiling or any other part of the Premises or Building) shall become the property of Landlord and shall remain upon and be surrendered with the Premises; provided, however, at Landlord’s sole election, upon written notice by Landlord to Tenant at the time Tenant submits the plans and specifications for the Tenant Alterations to Landlord for its approval, Tenant shall be obligated, at its sole cost and expense, to remove at the end of the Lease Term or earlier termination of this Lease all (or such portion as Landlord shall designate) of the Removal Alterations (hereinafter defined) (including Telecommunication Facilities), repair any damages resulting from such removal and return the Premises to the same condition as existed prior to the installation of such Removal Alterations, reasonable wear and tear excepted. As used herein, the term “Removal Alterations” means any Tenant Alterations (including all Telecommunications Facilities and/or cabling in the Premises or running between the Premises and any other portion of the Building) (i) which Landlord, in response to a Removal Inquiry (hereinafter defined) by Tenant, indicated to Tenant must be removed by Tenant at the end of the Term; or (ii) with respect to which Tenant did not deliver a Removal Inquiry to Landlord at the time Tenant sough Landlord’s approval of such Tenant Alteration (in accordance with the provisions of this paragraph 4.7). As used herein, the term “Removal Inquiry” means an inquiry by Tenant, made to Landlord contemporaneously with Tenant’s request for approval of any Tenant Alternation, as to whether or not such Alteration must be removed by Tenant at the end of the Lease Term. Tenant waives all rights to any payment or compensation for such Tenant Alterations (including Telecommunication Facilities). If Tenant shall fail to remove any of its property from the Premises, Building or Land at the expiration or earlier termination of this Lease, Landlord may, at its option, remove and store such property at Tenant’s expense without liability for loss of or damage to such property, such storage to be for the account and at the expense of Tenant. Tenant shall pay all reasonable, actual and documented costs incurred by Landlord within fifteen (15) Business Days after demand for such payment. If Tenant fails to pay the cost of storing any such property, Landlord may, at its option, after it has been stored for a period of thirty (30) days or more, sell or permit to be sold, any or all such property at public or private sale (and Landlord may become a purchaser at such sale), in such manner and at such times and places as Landlord in its sole discretion may deem proper, and Landlord shall apply the proceeds of such sale: first, to the cost and expense of such sale, including reasonable attorneys’ fees actually incurred; second, to the payment of the costs or charges for storing any such property; third, to the payment of any other sums of money which may then be or later become due Landlord from Tenant under this Lease; and, fourth, the balance, if any, to Tenant.

4.8 Access. Tenant shall have access to the Building and the Garage seven (7) days per week, twenty-four (24) hours per day, subject to Landlord’s rights set forth in paragraph 4.3.1, above. Tenant shall permit Landlord and Landlord’s Agents to enter into the Premises at any time on at least one (1) Business Day’s notice {except in case of emergency involving the possibility of injury or death to persons or damage to property within the Building, in which case no notice shall be required), subject to Tenant’s reasonable security requirements which had been delivered in writing to Landlord prior to the date of entry by Landlord, which may include the need to sign in, provide identification and, except in emergencies, be escorted by an employee of Tenant (provided that Tenant makes one of its employees available for such purpose during normal business hours on the date and time requested by Landlord) for the purpose of inspecting the same or for the purpose of repairing, altering or improving the Premises or the Building. Nothing contained in this paragraph 4.8 shall be deemed to impose any obligation upon Landlord not expressly stated elsewhere in this Lease. When reasonably necessary, and so long as same does not deprive Tenant of all reasonable access to the Premises, Landlord may temporarily close Building or Land entrances, Building doors or other facilities, without liability to Tenant by reason of such closure and without such action by Landlord being construed as an eviction of Tenant or as relieving Tenant from the duty of observing or performing any of the provisions of this Lease. Landlord shall have the right, upon one (1) Business Day’s prior notice to Tenant, to enter the Premises at any time during the last twelve (12) months of the Lease Term or at any time without notice during the occurrence of an Event of Default for the purpose of showing the Premises to prospective tenants and to erect on the Premises a suitable sign indicating the Premises are available. Tenant shall give written notice to Landlord at least ten (10) Business Days prior to vacating the Premises and shall arrange to meet with Landlord for a joint inspection of the Premises prior to vacating. In the event that Tenant fails to timely deliver such notice to Landlord and a joint inspection of the Premises does not occur prior to Tenant’s vacating the Premises or the last day of the Lease Term, whichever comes first (the “Outside Inspection Date”), Landlord’s inspection of the Premises upon one (1) Business Day’s notice to Tenant of such inspection after the Outside Inspection Date shall be conclusively deemed correct for purposes of determining Tenant’s responsibility for repairs and restoration, unless Tenant participates in such inspection. Landlord shall not be liable for the consequences of admitting by passkey, or refusing to admit to the Premises, Tenant or any of Tenant’s Agents, or other persons claiming the right of admittance.

4.9 Damage or Destruction.

4.9.1 If the Premises are damaged by fire, earthquake or other casualty (the “Casualty”). Tenant shall give Landlord prompt written notice thereof. If Landlord estimates (such estimate to be performed within forty-five (45) calendar days of Landlord’s actual knowledge of such damage) that the damage can be repaired in a manner necessary to cause it to be in the same condition as it was on the Tender Date within one hundred-eighty (180) days after Landlord becomes aware of such damage and provided that there are sufficient insurance proceeds available to repair such damage, then Landlord shall proceed with reasonable diligence to restore the Premises to substantially the condition which existed prior to the damage and this Lease shall not terminate. If, in Landlord’s estimation, the damage cannot be repaired within

such 180 day period, the destruction was cased by an uninsurable event or if there are insufficient insurance proceeds available to repair such damage (provided Landlord maintains the insurance coverage required by subparagraph 4.14.2, below), Landlord may elect in its sole discretion exercised in good faith to either: (a) terminate this Lease or (b) restore the Premises to substantially the same condition which existed on the Tender Date and this Lease will continue.

4.9.2 If Landlord elects to restore the Premises under subparagraph 4.9.1 above, then Landlord shall, at its sole cost and expense, restore the Premises with reasonable diligence to substantially the same condition existing on the Tender Date; provided that Landlord shall not be obligated to restore Tenant Improvements and Tenant Alterations installed by Tenant or Tenant’s furniture, fixtures or equipment. Landlord shall promptly provide Tenant with written notice of its election to restore the Premises, which notice shall also specify the expected duration of such restoration. Failure to so elect shall be deemed Landlord’s decision not to restore. Base Rent and Additional Rent shall be reduced during the period of Landlord’s restoration of the Premises in proportion to the portion of the Premises which is not usable (or accessible) by Tenant as a result of such casualty and is not being used by Tenant (except that in the event that the portion of the Premises which is rendered untenantable precludes Tenant from operating Tenant’s business in the balance of the Premises in the manner it had been conducted prior to the Casualty Date, then all Rent shall be fully abated) until the date on which Landlord substantially completes its restoration of the Premises to the condition as existing on the Tender Date. When performing such restoration, Landlord will not be obligated to spend more than the net insurance proceeds received by Landlord as a result of such Casualty plus an amount equal to the applicable deductible under Landlord’s insurance policy. Tenant agrees to look to the provider of Tenant’s insurance for coverage for the reconstruction of the Tenant Improvements and the Tenant Alterations, if any, and for the loss of Tenant’s use of the Premises and any other related losses or damages incurred by Tenant during any reconstruction period.

4.9.3 If the Building is damaged by fire, earthquake or other casualty and more than fifty percent (50%) of the Building is rendered untenantable, without regard to whether the Premises are affected by such damage, Landlord may in its absolute discretion, elect to terminate this Lease by notice in writing to Tenant within twenty (20) Business Days after the occurrence of such damage if Landlord is also terminating the leases of other tenants in the Building who are similarly situated to Tenant. Such notice shall be effective twenty (20) Business Days after receipt by Tenant unless a later date is set forth in Landlord’s notice.

4.9.4 Notwithstanding anything contained in this Lease to the contrary, if there is damage to the Premises or Building and the holder of any indebtedness secured by a mortgage or deed of trust covering any such property requires that the insurance proceeds be applied to such indebtedness or if the insurance proceeds are otherwise inadequate to complete the repair of the damages to the Premises, the Building or both, then Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within fifteen (15) Business Days after Landlord is notified of such requirement.

4.9.5 Notwithstanding the foregoing, if the Premises or the Building are wholly or partially damaged or destroyed by casualty within the final twelve (12) months of the Lease Term, either Landlord or Tenant may, at its option, elect to terminate this Lease upon written notice to the other party within thirty (30) days following such damage or destruction.

4.9.6 Notwithstanding anything in this Lease to the contrary, Tenant may terminate this Lease within thirty (30) days of delivery to Tenant of Landlord’s determination of the estimated time for the Premises or the Building to be restored if such estimated time exceeds one hundred eighty (180) days from the date of Landlord’s actual knowledge of the Casualty. In addition, if the actual time to restore in fact exceeds two hundred ten (210) days from the date Landlord becomes aware of the Casualty (subject to extension for Force Majeure Events), Tenant shall have the right to terminate this Lease, provided that Tenant delivers to Landlord, within ten (10) days of the expiration of such two hundred ten (210) day period, written notice of Tenant’s intention to terminate the Lease unless Landlord completes such restoration within thirty (30) days after Landlord’s receipt of such notice; provided if Landlord completes the restoration within such thirty (30) day period, the Lease shall not terminate and shall continue in full force and effect; provided further that if Landlord does not complete the restoration within such thirty (30) day period. Tenant may terminate this Lease by written notice to Landlord within ten (10) days after the end of such thirty (30) day period.

4.10 Condemnation. If more than fifty percent (50%) of the Premises, or such portions of the Building as may be required for the Tenant’s reasonable use of the Premises, are taken by eminent domain or by conveyance in lieu thereof, this Lease shall automatically terminate as of the date the physical taking occurs, and all Base Rent, Additional Rent and other sums payable under this Lease shall be paid to that date. In case of taking of a part of the Building that is not required for the Tenant’s reasonable use of the Premises, then this Lease shall continue in full force and effect and the Base Rent shall be equitably reduced based on the proportion by which the floor area of the Premises is reduced, such reduction in Base Rent to be effective as of the date the physical taking occurs. Additional Rent and all other sums payable under this Lease shall not be abated but Tenant’s Pro Rata Share (Operating Costs) and Tenant’s Pro Rata Share (Property Taxes) shall be redetermined as equitable under the circumstances. Landlord reserves all rights to damages or awards for any taking by eminent domain relating to the Premises, Building, Land and the unexpired term of this Lease. Tenant assigns to Landlord any right Tenant may have to such damages or award and Tenant shall make no claim against Landlord for damages for termination of its leasehold interest or interference with Tenant’s business, Tenant shall have the right, however, to claim and recover from the condemning authority compensation for any loss to which Tenant may be entitled for Tenant’s moving expenses the value of furnishings, equipment and trade fixtures installed in the Premises at Tenant’s sole cost, or other relocation costs; provided that, such expenses or costs may be claimed only if they are awarded separately in the eminent domain proceedings and not as a part of the damages recoverable by Landlord.

4.11 Parking. The Building’s parking garage is to be operated by Landlord or an independent contractor pursuant to a contract with Landlord. Such contract (if any) will allow Landlord to designate a certain number of permits for use by particular tenants during the entire Lease Term. Landlord agrees to instruct the parking garage operator to provide throughout the entire Lease Term, and Tenant may lease (either from Landlord or from such operator) up to the number of spaces allocated to Tenant in the definition of the Parking Ratio for use by Tenant’s employees. Tenant shall pay Landlord or such contractor the prevailing market rate (which rate will be comparable to rates then being charged at comparable office buildings in the Arlington, Virginia area, as reasonably determined by Landlord) for such unreserved parking, which shall be the same rate generally charged by Landlord or such contractor to its other customers paying for

unreserved parking in the Building. The current monthly charge for unreserved parking is $120.00 per month, which charge is subject to market-based increases (as reasonably determined by Landlord) from time-to-time by Landlord. Tenant’s parking privileges shall be subject to the reasonable rules and regulations relating to parking adopted by Landlord and/or the parking garage operator from time to time. Landlord shall have the right to grant designated, reserved parking spaces to other tenants in the Building. Landlord shall have no obligation whatsoever to monitor, secure or police the use of the parking or other common areas.

4.12 Indemnification.

4.12.1 Except to the extent arising from the negligence of Landlord or Landlord’s Agents, Tenant shall indemnify, defend and hold harmless Landlord and Landlord’s Agents from and against any and all third party Claims, arising in whole or in part out of (a) the possession, use or occupancy of the Premises or the business conducted in the Premises, (b) the negligence or willful misconduct of Tenant or Tenant’s Agents, or (c) any breach or default under this Lease by Tenant.

4.12.2 Except to the extent arising from the negligence of Tenant or Tenant’s Agents, Landlord shall indemnify, defend and hold harmless Tenant and Tenant’s Agents from and against any and all third party Claims, arising in whole or in part out of (a) the negligence or willful misconduct of Landlord or Landlord’s Agents, (b) the negligence or willful misconduct of Landlord’s contractors in connection with the performance of any construction work in the Building; or (c) any breach or default under this Lease by Landlord.

4.12.3 Except as otherwise specified in this Lease, neither Landlord nor Landlord’s Agents shall, to the extent permitted by law, have any liability to Tenant, or to Tenant’s Agents, for (a) any Claims arising out of any cause whatsoever, including repair to any portion of the Premises; (b) interruption in or interference with the use of the Premises or any equipment therein; (c) any accident or damage resulting from any use or operation by Landlord, Tenant or any person or entity of heating, cooling, electrical, sewerage or plumbing equipment or apparatus or Telecommunication Facilities; (d) termination of this Lease by reason of damage to the Premises or Building; (e) fire, robbery, theft, vandalism, mysterious disappearance or a casualty of any kind or nature; (f) actions of any other tenant of the Building or of any other person or entity; (g) inability to furnish any service required of Landlord as specified in this Lease; or (h) leakage in any part of the Premises or the Building from rain, ice or snow, or from drains, pipes or plumbing fixtures in the Premises or the Building. Landlord shall only be responsible for Claims arising from the items listed in the previous sentence if such items were within Landlord’s reasonable control and Landlord was negligent or acted with or willful misconduct in failing to repair or maintain the Building as required by this Lease; but in no event shall Landlord’s responsibility extend to any interruption to Tenant’s business or any indirect or consequential losses suffered by Tenant or Tenant’s Agents or extend beyond Landlord’s responsibility as set forth in paragraph 3.5 of this Lease (captioned “Utilities”) when that paragraph is applicable. The obligations of this paragraph 4.12 shall be subject to paragraph 4.15 of this Lease (captioned “Waiver of Subrogation”).

4.13 Tenant Insurance.

4.13.1 Tenant shall, throughout the Lease Term, at its own expense, keep and maintain in full force and effect the following policies, each of which shall be endorsed as needed to provide that the insurance afforded by these policies is primary and that all insurance carried by Landlord is strictly excess and secondary and shall not contribute with Tenant’s liability insurance:

(a) A policy of commercial general liability insurance, including a contractual liability endorsement covering Tenant’s obligations under paragraph 4.12 of this Lease (captioned “Indemnification”), insuring against claims of bodily injury and death or property damage or loss with a combined single limit at the Tender Date of this Lease of not less than Three Million Dollars ($3,000,000.00), which limit shall be reasonably increased during the Lease Term at Landlord’s request to reflect both increases in liability exposure arising from inflation as well as from changing use of the Premises or changing legal liability standards, which policy shall be payable on an “occurrence” rather than a “claims made” basis, and which policy names Landlord and Manager and, at Landlord’s written request Landlord’s mortgage lender(s) or investment advisors, as additional insureds;

(b) A policy of extended property insurance (which is commonly called “all risk”) covering Tenant Improvements, Tenant Alterations (including Telecommunication Facilities), and any and all furniture, fixtures, equipment, inventory, improvements and other property in or about the Premises which is not owned by Landlord, for one hundred percent (100%) of the then current replacement cost of such property;

(c) A policy or worker’s compensation insurance as required by applicable law and employer’s liability insurance with limits of no less than Five Hundred Thousand and No/100 Dollars ($500,000.00); and

(d) A policy of automobile liability insurance, including loading and unloading, and covering owned, non-owned and hired vehicles, with limits of no less than One Million Dollars ($1,000,000.00) per occurrence, if applicable.

4.13.2 All insurance policies required under this paragraph shall be with companies reasonably approved by Landlord which are authorized to conduct business in the Commonwealth of Virginia and possess a BEST rating of A-VII or better, and each policy shall state that the insurer will provide at least thirty (30) days’ written notice to Tenant prior to cancellation, lapse or reduction in coverage (except for cancellation for non-payment of premium, with respect to which the insurer will provide at least ten (10) days’ written notice to Tenant). Tenant shall notify Landlord in writing within three (3) Business Days after Tenant receives a notice from Tenant’s insurance company canceling or reducing coverage or threatening to cancel or reduce coverage under any of Tenant’s insurance policies. Tenant shall deliver to Landlord and, at Landlord’s request Landlord’s mortgage lender(s), prior to the Tender Date and from time to time thereafter, certificates evidencing the existence and amounts of all such policies.

4.13.3 If Tenant fails to acquire or maintain any insurance or provide any certificate required by this paragraph 4.13, Landlord may, but shall not be required to, obtain such insurance or certificates and the costs associated with obtaining such insurance or certificates shall be payable by Tenant to Landlord on demand.

4.14 Landlord’s Insurance. Landlord shall, throughout the Lease Term, keep and maintain in full force and effect:

4.14.1 A policy of commercial general liability insurance, insuring against claims of bodily injury and death or property damage or loss with a combined single limit at the Tender Date of not less than Five Million Dollars ($5,000,000.00), which policy shall be payable on an “occurrence” rather than a “claims made” basis;

4.14.2 A policy of extended property insurance (what is commonly called “all risk”) covering the Building and Landlord’s personal property, if any, located on the Land in the amount of one hundred percent (100%) of the then current replacement value of such property; and

4.14.3 Landlord may, but shall not be required to, maintain such other types of insurance as are customarily carried by the owners of comparable office buildings in the Arlington, Virginia market, including but not limited to, property insurance coverage for earthquakes and floods in such amounts as Landlord deems appropriate. Such policies may be “blanket” policies which cover other properties owned by Landlord.

4.15 Waiver of Subrogation. Notwithstanding anything in this Lease to the contrary, Landlord and Tenant hereby each waive and release the other from any and all Claims or any loss or damage that may occur to the Land, Building, Premises, Tenant Improvements, Tenant Alterations or personal property located in the Premises, by reason of fire or other casualty regardless of cause or origin, including without limitation the negligence or misconduct of Landlord, Tenant, Landlord’s Agents or Tenant’s Agents, but only to the extent of the insurance proceeds paid to such releasor under its policies of insurance or, if it fails to maintain the required policies, the insurance proceeds that would have been paid to such releasor if it had maintained such policies. Each party to this Lease shall promptly give to its insurance company written notice of the mutual waivers contained in this paragraph 4.15, and shall cause its insurance policies to be properly endorsed, if necessary, to prevent the invalidation of any insurance coverages by reason of the mutual waivers contained in this paragraph 4.15.

4.16 Assignment and Subletting by Tenant.

4.16.1 Except with respect to transfers pursuant to 4.16.7, below, Tenant shall not have the right to assign, transfer, mortgage or encumber this Lease in whole or in part, nor sublet the whole or any part of the Premises, nor allow the occupancy of all or any part of the Premises by another, without first obtaining Landlord’s consent, which consent may be granted or denied in accordance with this paragraph. Notwithstanding any permitted assignment or subletting, Tenant shall at all times remain directly, primarily and fully responsible and liable for the payment of all sums payable under this Lease and for compliance with all of its other obligations as tenant under this Lease. Landlord’s acceptance of Base Rent, Additional Rent or any other sum from any assignee, sublessee, transferee, mortgagee or encumbrance holder shall not be deemed to be Landlord’s approval of any such conveyance. Upon the occurrence of an Event of Default and

written notice to Tenant (unless Tenant is a debtor in a bankruptcy proceeding, in which event no notice shall be required), if the Premises or any part of the Premises are then subject to an assignment or subletting, Landlord may, at its option, collect directly from such assignee or subtenant all rents becoming due to Tenant under such assignment or sublease and apply such rents against any sums due to Landlord from Tenant under this Lease. No such collection shall be construed to constitute a novation or release of Tenant from the further performance of Tenant’s obligations under this Lease. Landlord’s right of direct collection shall be in addition to and not in limitation of any other rights and remedies provided for in this Lease or at law. Tenant makes an absolute assignment to Landlord of such assignments and subleases and any rent, Lease Security Deposits and other sums payable under such assignments and subleases as collateral to secure the performance of the obligations of Tenant under this Lease.

4.16.2 In the event Tenant desires to assign this Lease or to sublet all or any portion of the Premises, Tenant shall give written notice of such desire to Landlord setting forth the name of the proposed subtenant or assignee, the proposed term, the nature of the proposed subtenant’s or assignee’s business to be conducted on the Premises, the rental rate, and any other particulars of the proposed subletting or assignment that Landlord may reasonably request. Without limiting the preceding sentence, Tenant shall also provide Landlord with: (a) such financial information as Landlord may reasonably request concerning the proposed subtenant or assignee, including recent financial statements certified as accurate and complete by the president, managing partner or other appropriate officer of the proposed subtenant or assignee; (b) proof reasonably satisfactory to Landlord that the proposed subtenant or assignee will immediately occupy and thereafter use the entire Premises (or any sublet portion of the Premises) for the remainder of the Lease Term (or for the entire term of the sublease, if shorter) in compliance with the terms of this Lease; and (c) a copy of the proposed sublease or assignment or letter of intent. Tenant shall pay to Landlord, upon Landlord’s demand therefor, Landlord’s reasonable attorneys’ fees incurred in the review of such documentation and in documenting Landlord’s consent (not to exceed $1,500.00 in the aggregate). Receipt of such fee shall not obligate Landlord to approve the proposed assignment or sublease.

4.16.3 Without limiting what may be construed as a factor considered by Landlord, Tenant agrees that any one or more of the following will be proper grounds for Landlord’s disapproval of a proposed assignment or sublease:

(a) The proposed assignee or subtenant does not, in Landlord’s good faith judgment, have financial worth or creditworthiness or sufficient financial worth to insure full and timely performance under this Lease; or Landlord has received insufficient evidence of the financial worth or creditworthiness of the proposed assignee or subtenant to make the determination set forth in this clause;

(b) Landlord has had prior negative leasing experience with the proposed assignee or subtenant or believes, in Landlord’s reasonable judgment, the proposed assignee or subtenant is engaged in a business, or the Premises or any part of the Premises will be used in a manner, that is not in keeping with the then standards of the Building, or that is inappropriate for the Building, or that will violate any negative covenant as to use contained in any other lease of space in the Building;

(d) An Event of Default has occurred and remains uncured under this Lease.

4.16.4 Within fifteen (15) Business Days after Landlord’s receipt of all required information to be supplied by Tenant pursuant to this paragraph 4.16, Landlord shall notify Tenant of Landlord’s approval, disapproval or conditional approval of any proposed assignment or subletting or, subject to the terms and conditions set forth in subparagraph 4.16.7, below, of Landlord’s election to recapture as described below. Any instance of disapproval or conditional approval by Landlord shall be delivered to Tenant with reasons therefor in reasonable detail. Landlord shall have no obligation to respond unless and until all required information has been submitted. In the event Landlord approves of any proposed assignment or subletting, Tenant and the proposed assignee or sublessee shall execute and deliver to Landlord an assignment (or subletting) and assumption agreement in form and content reasonably satisfactory to Landlord.

4.16.5 Any transfer, assignment or hypothecation of any of the stock or interest in Tenant, or the assets of Tenant, or any other transaction, merger, reorganization or event, however constituted which (a) results in fifty percent (50%), or more of such stock, interest or assets going into different ownership; provided, however, that: (i) Tenant may assign its entire interest under this Lease or sublet the Premises to any successor to Tenant by purchase, merger, consolidation or reorganization, provided that (A) after such transaction is completed the net worth and creditworthiness of the successor entity is equal to or greater than those of Tenant prior to such purchase, merger, consolidation or reorganization; and (B) such transaction includes a transfer of a majority or controlling interest in Tenant made in connection with an initial public offering of the stock of Tenant, and (ii) after Tenant has become a publicly-traded corporation, any subsequent transfer of a majority or controlling interest of Tenant on a nationally recognized public stock exchange shall not constitute an assignment of this Lease which requires Landlord’s approval (hereinafter, collectively, referred to as “Permitted Transfer”), or (b) is a subterfuge denying Landlord the benefits of this paragraph, shall be deemed to be an assignment within the meaning and provisions of this paragraph and shall be subject to the provisions of this paragraph 4.16.

4.16.6 If Landlord consents to any assignment or sublease and Tenant receives rent or any other consideration, either initially or over the term of the assignment or sublease, in excess of the Base Rent and Additional Rent (or, in the case of a sublease of a portion of the Premises, in excess of the Base Rent paid by Tenant on a square footage basis under this Lease), Tenant shall pay to Landlord fifty percent (50%) of such excess, after deducting any reasonable out-of-pocket advertising, leasing commissions, or other marketing costs and improvements or other out-of-pocket concessions incurred in connection with such assignment or sublease.

4.16.7 In the event that Tenant provides Landlord with written notice of Tenant’s desire to assign this Lease or sublet all or any portion of the Premises pursuant to Section 4.16.2, above, unless such assignment or sublease is undertaken in connection with a Permitted Transfer, Landlord shall have the right to recapture the Premises or the applicable portion thereof (a “Recapture”) by giving written notice of such Recapture to Tenant within fifteen (15) Business Days after receipt of Tenant’s written request for Landlord’s consent to such proposed

assignment or subletting. Tenant shall have no right to retract its request for Landlord’s consent to assign or sublease once such request has been made. Such Recapture shall terminate this Lease as to the applicable space effective on the prospective effective date of assignment or subletting, which shall be the last day of a calendar month and shall not be earlier than forty-five (45) Business Days after receipt of Tenant’s request hereunder. If less than the entire Premises are recaptured, this Lease shall remain in full force and effect with respect to that remaining area not recaptured by Landlord. Tenant shall surrender that portion of the Premises recaptured by Landlord in accordance with the terms and conditions of this Lease. Notwithstanding the first sentence of this subparagraph 4.16.7, Landlord shall have no right to Recapture the Premises or applicable portion thereof if: (a) Tenant’s proposed assignment or sublet is to a Qualified Tenant Affiliate, or (b) Tenant’s proposed sublet (i) is for a term that is less than 90% of the remaining Lease Term; and (ii) together with any previous sublets encompass, in the aggregate, net rentable area less than seventy-five percent (75%) of the total net rentable area of Premises.

4.16.8 Notwithstanding the above restrictions on subletting and assignments, Landlord’s prior consent shall not be required for any assignment or subletting to an Affiliate of Tenant (as defined below) or a Parent of Tenant (as defined below), provided (a) that such assignee has a creditworthiness (e.g. assets and capitalization) and net worth (which shall be determined on a pro forma basis using generally accepted accounting principles consistently applied and using the most recent financial statements) not less than that of Tenant as of the Effective Date, (b) that such assignee or subtenant agrees in writing to be bound by the terms and conditions of this Lease and to assume all of the obligations and liabilities of Tenant under this Lease, (c) that Tenant provides Landlord with prior written notice of its intent to assign or sublease all or a portion of the Premises not more than sixty (60) nor less than thirty (30) days prior to the effective date of such assignment or sublease, and (d) that the proposed assignment or sublease with such person or entity is not a so-called “sham” transaction intended by Tenant to circumvent the provisions of this paragraph 4.16. In the event of any assignment or subletting pursuant to this paragraph 4.16.8, Tenant shall remain fully liable as a primary obligor and principal for Tenant’s obligations and responsibilities under this Lease, including, but not limited to, the payment of all rent and charges required hereunder and the performance of all conditions and obligations to be performed under this Lease. For purposes of this paragraph 4.16.8., an “Affiliate of Tenant” shall mean any corporation, limited liability company, association, trust, or partnership (i) that Controls (as herein defined) Tenant, (ii) that is under the Control of Tenant, through stock ownership or otherwise, (iii) that is under common Control with Tenant, or (D) which results from the merger or consolidation with Tenant, or acquires all or substantially all of the assets of and interest in Tenant. For the purposes hereof, a “Parent of Tenant” shall mean any corporation, limited liability company, association, trust, or partnership (A) that Controls Tenant, or (B) that owns more than fifty percent (50%) of the issued and outstanding voting securities of Tenant. The terms “Control” or “Controls” as used in this paragraph 4.16.8 shall mean the power to directly or indirectly influence the direction, management, or policies of Tenant or such other entity. As used in this Lease, the term “Qualified Tenant Affiliate” means an Affiliate of Tenant or Parent of Tenant who has taken an assignment of this Lease or has subleased the Premises in accordance with the terms of this paragraph 4.16.8.

4.16.9 Notwithstanding anything to the contrary set forth herein and provided that no Event of Default shall have occurred and remains uncured, Tenant shall be entitled, without Landlord’s consent but on at least ten (10) business days’ notice to Landlord, to enter into license

agreements acceptable to Landlord with one or more of Tenant’s clients or subcontractors (the “Approved Users”) pursuant to which such Approved Users may use in the ordinary course of, and incidental to. Tenant’s business, portions of the Premises (which agreements shall not involve, in the aggregate, more than ten percent (10%) of the rentable square footage of the Premises at any one time), for general office use, provided Tenant evidences to Landlord’s reasonable satisfaction that: (i) such use is related to Tenant’s business in the Premises, (ii) such Approved User complies with the terms of this Lease, including without limitation all the rules and regulations set forth herein, (iii) such Approved User’s use of the Premises by the Approved User shall be in compliance with all Governmental Requirements and in accordance with paragraph 2.7 of this Lease, (iv) the portion of the Premises used pursuant to this paragraph 4.16.9 does not have a separate entrance and is not separated from the other portions of the Premises by demising walls or similar partitions, unless Landlord requires or approves same, (v) such Approved User does not impose any additional burden upon Landlord in the operation of the Building, (vi) such Approved User’s use of the Premises does not have any adverse impact on the operations of the Building and/or the Building systems, and (vii) such Approved User agrees to indemnify Landlord for and against all damage, claims and liability arising out of such Approved User’s use of a portion of the Premises. Any default of any provision hereunder caused by any such Approved User shall be deemed a default of such provision by Tenant, and any act or omission by such Approved User shall be deemed the act or omission of Tenant. Nothing contained in this Lease (including the provisions of this paragraph 4.16.9) or otherwise (including the provision of any services to the Premises) shall be deemed to (A) create any landlord-tenant or other relationship between Landlord and any Approved User, or (B) create any contractual liability or duty on the part of Landlord to any Approved User. 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 reasonable attorneys’ fees) incurred by or claimed against Landlord and/or its agents, officers, directors and employees, directly or indirectly, as a result of or in any way arising from any Approved User’s use and occupancy of any portion of the Premises.

4.17 Assignment by Landlord. Landlord shall have the right to transfer and assign, in whole or in part, its rights and obligations under this Lease and in any and all of the Land or Building. If Landlord sells or transfers any or all of the Building, including the Premises, Landlord and Landlord’s Agents shall, upon consummation of such sale or transfer, be released automatically from any liability relating to obligations or covenants under this Lease to be performed or observed after the date of such transfer, and in such event, Tenant agrees to look solely to Landlord’s successor-in-interest with respect to such liability; provided that, as to the Lease Security Deposit and Prepaid Rent, Landlord shall not be released from liability therefor unless Landlord has delivered (by direct transfer or credit against the purchase price) the Lease Security Deposit or Prepaid Rent to its successor-in-interest.

4.18 Estoppel Certificates and Financial Statements. Tenant shall, from time to time, upon the written request of Landlord, execute, acknowledge and deliver to Landlord or its designee a written statement stating (to the extent factually accurate): (a) the date this Lease was executed and the date it expires; (b) the date Tenant entered into occupancy of the Premises; (c) the amount of monthly Base Rent and Additional Rent and the date to which such Base Rent and Additional Rent have been paid; and (d) certifying that (1) this Lease is in full force and effect and has not been assigned, modified, supplemented or amended in any way (or specifying the

date of the agreement so affecting this Lease); (2) Landlord is not in breach of this Lease (or, if so, a description of each such breach) and that no event, omission or condition has occurred which would result, with the giving of notice or the passage of time, in a breach of this Lease by Landlord; (3) this Lease represents the entire agreement between the parties with respect to the Premises; (4) all required contributions by Landlord to Tenant on account of Tenant Improvements have been received; (5) on the date of execution, there exist no defenses or offsets which the Tenant has against the enforcement of this Lease by the Landlord; (6) no Base Rent, Additional Rent or other sums payable under this Lease have been paid in advance except for Base Rent and Additional Rent for the then current month; (7) no security has been deposited with Landlord (or, if so, the amount of such security); (8) it is intended that any Tenant’s statement may be relied upon by a prospective purchaser or mortgagee of Landlord’s interest or an assignee of any such mortgagee; and (9) such other information as may be reasonably requested by Landlord. If Tenant fails to respond within ten (10) Business Days of its receipt of a written request by Landlord as provided in this paragraph 4.18, such shall be a breach of this Lease and Tenant shall be deemed to have admitted the accuracy of any information supplied by Landlord to a prospective purchaser, mortgagee or assignee. In addition, Tenant shall, from time to time, but not more than once in any twelve (12) month period (except if the Landlord is then attempting to sell or refinance the Building or if an Event of Default then exists) upon the written request of Landlord, deliver to or cause to be delivered to Landlord or its designee then current financial statements (including a statement of operations and balance sheet and statement of cash flows) certified as accurate and prepared in conformance with generally accepted accounting principles for (i) Tenant, (ii) any entity which owns a controlling interest in Tenant, (iii) any successor entity to Tenant by merger or operation of law, and (iv) any guarantor of this Lease.

4.19 Modification for Lender. If, in connection with obtaining construction, interim or permanent financing for the Building or Land, Landlord’s lender, if any, shall request reasonable modifications to this Lease as a condition to such financing, Tenant will not unreasonably withhold or delay its consent to such modifications; provided that, such modifications do not increase the obligations of Tenant, or decrease the obligations of Landlord under this Lease or materially adversely affect Tenant’s rights under this Lease.

4.20 Hazardous Substances.

4.20.1 Neither Tenant, any of Tenant’s Agents nor any other person shall store, place, generate, manufacture, refine, handle, or locate on, in, under or around the Land or Building any Hazardous Substance, except for storage, handling and use of reasonable quantities and types of cleaning fluids and office supplies in the Premises in the ordinary course and the prudent conduct of Tenant’s business in the Premises. Tenant agrees that (a) the storage, handling and use of such permitted Hazardous Substances must at all times conform to all Governmental Requirements and to applicable fire, safety and insurance requirements; (b) the types and quantities of permitted Hazardous Substances which are stored in the Premises must be reasonable and appropriate to the nature and size of Tenant’s operation in the Premises and reasonable and appropriate for a first-class building of the same or similar use and in the same market area as the Building; and (c) no Hazardous Substance shall be spilled or disposed of on, in, under or around the Land or Building or otherwise discharged from the Premises or any area adjacent to the Land or Building. In no event will Tenant be permitted to store, handle or use on, in, under or around the Premises any Hazardous Substance which will increase the rate of fire or

extended coverage insurance on the Land or Building, unless: (1) such Hazardous Substance and the expected rate increase have been specifically disclosed in writing to Landlord; (2) Tenant has agreed in writing to pay any rate increase related to each such Hazardous Substance; and (3) Landlord has approved in writing each such Hazardous Substance, which approval shall be subject to Landlord’s discretion.

4.20.2 Tenant shall indemnify, defend and hold harmless Landlord and Landlord’s Agents from and against any and all Claims arising out of any breach of any provision of this paragraph 4.20, which expenses shall also include laboratory testing fees, personal injury claims, clean-up costs and environmental consultants’ fees. Tenant agrees that Landlord may be irreparably harmed by Tenant’s breach of this paragraph 4.20 and that a specific performance action may appropriately be brought by Landlord; provided that, Landlord’s election to bring or not bring any such specific performance action shall in no way limit, waive, impair or hinder Landlord’s other remedies against Tenant.

4.20.3 As of the execution date of this Lease, Tenant represents and warrants to Landlord that, except as otherwise disclosed by Tenant to Landlord, Tenant has no intent to bring any Hazardous Substances on, in or under the Premises except for the type and quantities authorized in the subparagraph 4.20.1, above.

4.20.4 Landlord represents and warrants that, to the best of its actual knowledge, without any independent inquiry or investigation, as of the Effective Date, there are no Hazardous Substances in the Premises, nor in the portions of the common areas of the Building that would impact Tenant’s use and occupancy of the Premises, which are in violation of applicable Governmental Requirements. Landlord covenants not to bring onto the Land or Building during the Lease Term any Hazardous Substances in violation of any Governmental Requirements.

4.21 Access Laws.

4.21.1 Tenant agrees to notify Landlord as soon as reasonably possible if Tenant receives notification or otherwise becomes aware of: (a) any condition or situation on, in, under or around the Land or Building which may constitute a violation of any Access Laws or (b) any threatened or actual lien, action or notice that the Land or Building is not in compliance with any Access Laws. If Tenant is responsible for such condition, situation, lien, action or notice under this paragraph 4.21, Tenant’s notice to Landlord shall include a statement as to the actions Tenant proposes to take in response to such condition, situation, lien, action or notice.

4.21.2 Tenant shall not alter or permit any assignee or subtenant or any other person to alter the Premises in any manner which would violate any Access Laws or increase Landlord’s responsibilities for compliance with Access Laws, without the prior approval of the Landlord. In connection with any such approval, Landlord may require a certificate of compliance with Access Laws from an architect, engineer or other person acceptable to Landlord. Tenant agrees to pay the reasonable, actual and documented fees incurred by such architect, engineer or other third party in connection with the issuance of such certificate of compliance. Landlord’s consent to any proposed Tenant Alteration shall (a) not relieve Tenant of its obligations or indemnities contained in this paragraph or this Lease or (b) be construed as a warranty that such proposed alteration complies with any Access Law.

4.21.3 Tenant shall be solely responsible for all costs and expenses relating to or incurred in connection with: (a) failure of the Premises to comply with the Access Laws; and (b) bringing the Building and the common areas of the Building into compliance with Access Laws, if and to the extent such noncompliance arises out of or relates to: (1) Tenant’s specific use of the Premises, including the hiring of employees; (2) any Tenant Alterations to the Premises; or (3) any Tenant Improvements constructed in the Premises by or at the request of Tenant.

4.21.4 Landlord shall be responsible for all costs and expenses relating to or incurred in connection with bringing the common areas of the Building into compliance with Access Laws, unless such costs and expenses are Tenant’s responsibility as provided in the preceding subparagraph 4.21.3. Any cost or expense paid or incurred by Landlord to bring the Premises or common areas of the Building into compliance with Access Laws which is not Tenant’s responsibility under the preceding subparagraphs shall be amortized over the useful economic life of the improvements with interest at the Prime Rate plus four (4) percentage points compounded daily, and, except as otherwise expressly provided herein, shall be an Operating Cost for purposes of this Lease.

4.21.5 Tenant agrees to indemnify, defend and hold harmless Landlord and Landlord’s Agents from and against any and all Claims arising out of or relating to any failure of Tenant or Tenant’s Agents to comply with Tenant’s obligations under this paragraph 4.21. Landlord represents and warrants that, to the best of its actual knowledge, without any independent inquiry or investigation, as of the Effective Date: (a) the portions of the common areas of the Building that affect Tenant’s use and occupancy of the Premises (the “Applicable Portion of the Common Areas”) are in substantial compliance with applicable Governmental Requirements (including the Access Laws), the violation of which would affect Tenant’s use and enjoyment of the Premises, and (b) the Applicable Portion of the Common Areas is in substantial compliance with the Access Laws in effect on the Effective Date.

4.21.6 The provisions of this paragraph 4.21 shall supersede any other provisions in this Lease regarding Access Laws, to the extent inconsistent with the provisions of any other paragraphs of this Lease.

4.22 Quiet Enjoyment. Landlord covenants that, provided that no Event of Default exists hereunder: (a) Tenant, upon paying Base Rent, Additional Rent and all other sums payable under this Lease and performing all covenants and conditions required of Tenant under this Lease; (b) Tenant shall and may peacefully have, hold and enjoy the Premises without hindrance or molestation by Landlord subject to the provisions of this Lease.

4.23 Signs.

4.23.1 Exterior. So long as (a) Governmental Requirements permit Landlord to install on the top of the Building, after the installation of, and in addition to, the Exterior Building Sign (hereinafter defined), an exterior sign of a size substantially similar to the Exterior Building Sign, (b) Tenant leases at least 42,128 rentable square feet of office space in the Building, (c) Tenant remains one of the two largest tenants in the Building based on the rentable area leased in the Building, and (d) no Event of Default shall have occurred and remains uncured, Tenant, at Tenant’s sole cost and expense, shall have the non¬exclusive right to install one (1) exterior

building sign (the “Exterior Building Sign”) containing Tenant’s name and/or Tenant’s corporate logo in the location on the exterior of the Building which is shown on the attached Exhibit F. Tenant’s right to install such Exterior Building Sign shall commence six (6) months prior to the Tender Date, provided that, prior to installing the Exterior Building Sign, Tenant shall have: (i) delivered the Letter of Credit to Landlord; and (ii) waived in writing its right to terminate this Lease pursuant to Section 2.4, above. At Tenant’s option, the Exterior Building Sign may be back-lit (subject to Landlord’s approval of Tenant’s lighting plan). Tenant may install the Exterior Building Sign in the location shown on the attached Exhibit F, provided that (A) Tenant provides to Landlord evidence reasonably satisfactory to Landlord that the Exterior Building Sign is permitted under, and conforms to, all applicable Governmental Requirements, (B) Tenant has obtained all permits, licenses and approvals (with Landlord’s reasonable cooperation but at no cost or liability to Landlord) that may be required in order to install the Exterior Building Sign, and (C) Tenant provides to Landlord evidence reasonably satisfactory to Landlord that Governmental Requirements would not prohibit an additional sign of similar size being placed on the top of the Building after the Exterior Building Sign has been installed. The exact size, dimensions, style, design, lighting, wiring, dimensions and all other components of the Exterior Building Sign shall be subject to Landlord’s approval, in its sole discretion exercised in good faith, provided in no event shall the dimensions of, or lettering on, the Exterior Building Sign be larger than those shown on the attached Exhibit F. Landlord reserves the right to approve in its sole discretion the manner in which the Exterior Building Sign is affixed to the Building. In order to obtain Landlord’s approval of the installation of the Exterior Building Sign, Tenant must submit to Landlord for its approval samples of materials to be used for the Exterior Building Sign (showing, among other things, the thickness thereof), samples of any colors to be used for the Exterior Building Sign, complete shop drawings of the Exterior Building Sign and plans and specifications for the actual construction and method of attachment to the Building of the Exterior Building Sign. The Exterior Building Sign shall be installed by a contractor reasonably approved by Landlord, which satisfies the Contractor Requirements. Throughout the Lease Term, Tenant shall be solely responsible for maintaining the Exterior Building Sign in first-class condition and repair, using a contractor reasonably approved by Landlord. If Tenant fails to properly maintain or repair the Exterior Building Sign, Landlord may, at its sole option: (A) require that Tenant remove the Exterior Building Sign and restore the portions of the Building affected by such removal to their condition immediately prior to the installation of the Exterior Building Sign; or (B) following ten (10) days’ written notice, and Tenant’s failure to effect such maintenance or repair of the Exterior Building Sign within such period, undertake such maintenance or repair at Tenant’s sole cost and expense; or (C) following fifteen (15) days’ written notice to Tenant and Tenant’s failure to effect such removal and restoration of the Exterior Building Sign within such period, remove the Exterior Building Sign and restore the portions of the Building affected by such removal, all at Tenant’s sole cost and expense. On or before the end of the Lease Term, or in the event that (1) Governmental Requirements prevent Landlord from installing on the top of the Building, in addition to the Exterior Building Sign, an exterior sign of a size substantially similar to the Exterior Building Sign, (2) Tenant assigns this Lease to an entity other than a Qualified Tenant Affiliate, (3) Tenant leases less than 42,128 rentable square feet of office space in the Building, or (4) Tenant is not one of the two largest tenants in the Building based on the rentable area leased in the Building, Tenant shall, at its sole cost and expense, have a contractor reasonably approved by Landlord remove the Exterior Building Sign and restore the portions of the Building affected by such removal to the condition

which existed immediately prior to the installation of the Exterior Building Sign, excepting ordinary wear and tear and damages from casualty the responsibility for the repair of which is Landlord’s under this Lease. If Tenant fails to timely remove the Exterior Building Sign or fails to restore the Building in accordance with the terms of the immediately preceding sentence, Landlord shall have the right, but not the obligation, to undertake such removal and/or restoration and Tenant shall reimburse Landlord for all reasonable, actual and documented costs incurred by Landlord in connection therewith, immediately upon demand therefor. Tenant shall obtain property insurance coverage for the Exterior Building Sign and such Exterior Building Sign shall be included in Tenant’s comprehensive liability insurance required pursuant to the Lease. Tenant’s rights under this paragraph 4.23 are personal to OPower, Inc., and no assignee (other than a Qualified Tenant Affiliate) or sublessee of all or any portion of the Premises shall have any exterior signage rights hereunder. 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 reasonable 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 the installation, maintenance, repair, operation, removal or existence of the Exterior Building Sign.

4.23.2 Interior. Landlord shall provide to Tenant, on a one-time basis, promptly after the Commencement Date, a Building standard suite entry sign approved by Landlord at Landlord’s reasonable cost and expense. Tenant shall not be responsible for the cost of removal (i) at the expiration of the Lease Term or earlier termination of the Lease of any Building standard suite entry signage approved by Landlord; however, all repair, modification or maintenance costs of same during the Lease Term shall be at Tenant’s sole cost and expense. Landlord, at its sole cost and expense, shall provide Tenant with Tenant’s pro-rata share of lobby directory strips in the lobby directory. Tenant shall not inscribe an inscription, or post, place, or in any manner display any sign, notice, picture, placard or poster, or any advertising matter whatsoever, anywhere in or about the Land or Building at places visible (either directly or indirectly as an outline or shadow on a glass pane) from anywhere outside the Premises without first obtaining Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

4.24 Subordination. Landlord represents that no deed of trust or mortgage encumbers the Land or Building on the Effective Date. Tenant subordinates this Lease and all rights of Tenant under this Lease to any mortgage, deed of trust, ground lease or vendor’s lien, or similar instrument which may from time to time be placed upon the Premises (and all renewals, modifications, replacements and extensions of such encumbrances), and each such mortgage, deed of trust, ground lease or lien or other instrument shall be superior to and prior to this Lease; provided however, Landlord shall use commercially reasonable efforts to obtain from any future mortgage lender (the “Mortgagee”) a subordination, non-disturbance and attornment agreement (“SNDA”) providing that Tenant’s rights to possession shall not be disturbed so long as no Event of Default then exists hereunder on such Mortgagee’s standard form of SNDA (an “Acceptable SNDA”). Notwithstanding the foregoing, any such Mortgagee or the holder of, or lessor or beneficiary under, any ground lease, vendor’s lien or similar instrument shall have the right to subordinate or cause to be subordinated any such mortgage, deed of trust, ground lease, vendor’s lien or similar instrument to this Lease. Subject to Tenant receiving an Acceptable SNDA, Tenant shall within ten (10) Business Days of any request, execute, acknowledge and deliver

promptly in recordable form any factually accurate and reasonable instrument or subordination agreement that Landlord or such holder may request. Subject to Tenant receiving an Acceptable SNDA, Tenant further covenants and agrees that if the lender or ground lessor acquires the Premises as a purchaser at any foreclosure sale or otherwise, Tenant shall recognize and attorn to such party as landlord under this Lease, and shall make all payments required hereunder to such new landlord without deduction or set-off and, upon the request of such purchaser or other successor, execute, deliver and acknowledge documents confirming such attornment. Tenant waives the provisions of any law or regulation, now or hereafter in effect, which may give or purport to give Tenant any right to terminate or otherwise adversely affect this Lease or the obligations of Tenant hereunder in the event that any such foreclosure or termination or other proceeding is prosecuted or completed.

4.25 Brokers. Each party to this Lease shall indemnify, defend and hold harmless the other party from and against any and all Claims asserted against such other party by any real estate broker, finder or intermediary relating to any act of the indemnifying party in connection with this Lease.

4.26 Limitation on Recourse. Liability with respect to the entry and performance of this Lease by or on behalf of Landlord, however it may arise, shall be asserted and enforced only against Landlord’s estate and equity interest in the Building. Neither Landlord nor any of Landlord’s Agents shall have any personal liability in the event of any claim against Landlord arising out of or in connection with this Lease, the relationship of Landlord and Tenant or Tenant’s use of the Premises. Further, in no event whatsoever shall any Landlord’s Agent have any liability or responsibility whatsoever arising out of or in connection with this Lease, the relationship of Landlord and Tenant or Tenant’s use of the Premises. Any and all personal liability, if any, beyond that which may be asserted under this paragraph 4.26, is expressly waived and released by Tenant and by all persons claiming by, through or under Tenant.

4.27 Mechanic’s Liens and Tenant’s Personal Property Taxes.

4.27.1 Tenant shall have no authority, express or implied, to create or place any lien or encumbrance of any kind or nature whatsoever upon, or in any manner to bind, the interest of Landlord or Tenant in the Premises or to charge the rentals payable under this Lease for any Claims in favor of any person dealing with Tenant, including those who may furnish materials or perform labor for any construction or repairs. Tenant shall within thirty (30) days after invoice, pay or cause to be paid all sums legally due and payable by it on account of any labor performed or materials furnished in connection with any work performed on the Premises on which any lien is or can be validly and legally asserted against its leasehold interest in the Premises and Tenant shall indemnify, defend and hold harmless Landlord from any and all Claims arising out of any such asserted Claims. Tenant agrees to give Landlord immediate written notice of any such asserted Claim.

4.27.2 Tenant shall be liable for all taxes levied or assessed against personal property, furniture or fixtures placed by Tenant in the Premises. If any such taxes for which Tenant is liable are levied or assessed against Landlord or Landlord’s property and Landlord elects to pay them or if the assessed value of Landlord’s property is increased by inclusion of such personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, Tenant shall reimburse Landlord for the sums so paid by Landlord, upon demand by Landlord.

SECTION 5: DEFAULT AND REMEDIES

5.1 Events of Default.

5.1.1 The occurrence of any one or more of the following events shall constitute a material default and breach of this Lease by Tenant (“Event of Default”):

(a) failure by Tenant to make any payment of Base Rent, Additional Rent or any other sum payable by Tenant under this Lease within five (5) Business Days after written notice from Landlord; provided that an Event of Default shall exist on the sixth (6,h) Business Day after the date on which such Rent payment was due (and no written notice to Tenant shall be required for an Event of Default to exist), if, as of the date on which such payment of Rent was due, Tenant is a debtor in a voluntary or involuntary bankruptcy proceeding;

(b) failure by Tenant to observe or perform any covenant or condition of this Lease, other than the making of payments, where such failure shall continue for a period of twenty (20) Business Days after written notice from Landlord or such additional time as is reasonably needed to cure the default provided that Tenant shall diligently pursue the cure and complete the cure within sixty (60) Business Days;

(c) the failure of Tenant to surrender possession of the Premises at the expiration or earlier termination of this Lease in the condition required by this Lease;

(d) (1) the making by Tenant of any general assignment or general arrangement for the benefit of creditors; (2) the filing by or against Tenant of a petition in bankruptcy, including reorganization or arrangement, unless, in the case of a petition filed against Tenant, unless the same is dismissed within thirty (30) Business Days; (3) the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located in the Premises or of Tenant’s interest in this Lease; (4) any execution, levy, attachment or other process of law against Tenant’s interest in this Lease, unless the same is dismissed within thirty (30) Business Days; (5) adjudication that Tenant is bankrupt; or (6) the making by Tenant of a transfer in fraud of creditors;

(e) any information furnished by or on behalf of Tenant to Landlord in connection with the entry of this Lease is determined to have been materially false, misleading or incomplete when made and Tenant knew or should have known that such information was false, misleading or incomplete;

(f) a failure of Tenant to deliver the Letter of Credit within the time period specified in the paragraph 3.3, above; or

(g) a failure of Tenant to renew or extend the Letter of Credit at least thirty (30) days prior to its expiration date.

5.1.2 Tenant shall notify Landlord promptly of any Event of Default or any facts, conditions or events which, with the giving of notice or passage of time or both, would constitute an Event of Default.

5.1.3 If a petition in bankruptcy is filed by or against Tenant, and if this Lease is treated as an “unexpired lease” under applicable bankruptcy law in such proceeding, then Tenant agrees that Tenant shall not attempt nor cause any trustee to attempt to extend the applicable time period within which this Lease must be assumed or rejected.

5.2 Remedies. If any Event of Default occurs, Landlord may at any time after such occurrence, with or without notice or demand except as stated in this paragraph 5.2, and without limiting Landlord in the exercise of any right or remedy at law which Landlord may have by reason of such Event of Default, exercise the rights and remedies, either singularly or in combination, as are specified or described in the subparagraphs of this paragraph 5.2.

5.2.1 Landlord may terminate this Lease and all rights of Tenant under this Lease either immediately or at some later date by giving Tenant written notice that this Lease is terminated. If Landlord so terminates this Lease, then Landlord may recover from Tenant the sum of:

(a) the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which have been earned at the time of termination;

(b) interest at the Default Rate on the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which have been earned at the time of termination; plus

(c) the amount by which the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which would have been earned after termination until the time of award exceeds the amount of such rental loss, if any, as Tenant affirmatively proves could have been reasonably avoided and interest on such excess at the Default Rate; plus

(d) any other reasonable amount necessary to compensate Landlord for the detriment proximately caused by Tenant’s failure to perform Tenant’s obligations under this Lease, including, leasing commissions, tenant improvement costs, renovation costs and advertising costs.

5.2.2 Landlord shall also have the right, with or without terminating this Lease, to re-enter the Premises pursuant to applicable law and take possession of the Premises and evict Tenant therefrom and remove all persons and property from the Premises. Landlord may cause property so removed from the Premises to be stored in a public warehouse or elsewhere at the expense and for the account of Tenant.

5.2.3 Landlord shall also have the right, without terminating this Lease, to accelerate and recover from Tenant the sum of all unpaid Base Rent, Additional Rent and all other sums payable under the then remaining Lease Term, discounting such amount to present value at the Prime Rate.

5.2.4 If Tenant vacates, abandons or surrenders the Premises without continuing to pay Base Rent and/or Additional Rent, or if Landlord re-enters the Premises as provided in

subparagraph 5.2.2 or takes possession of the Premises pursuant to legal proceedings or through any notice procedure provided by law, then, if Landlord does not elect to terminate this Lease, Landlord may, from time to time, without terminating this Lease, either (a) recover all Base Rent, Additional Rent and all other sums payable under this Lease as they become due or (b) relet the Premises or any part of the Premises on behalf of Tenant for such term or terms, at such rent or rents and pursuant to such other provisions as Landlord, in its sole discretion, may deem advisable, all with the right, at Tenant’s cost, to make repairs to the Premises and recover any deficiency from Tenant as set forth in subparagraph 5.2.6.

5.2.5 None of the following remedial actions, singly or in combination, shall be construed as an election by Landlord to terminate this Lease unless Landlord has in fact given Tenant written notice that this Lease is terminated: (a) an act by Landlord to maintain or preserve the Premises; (b) any efforts by Landlord to relet the Premises; (c) any repairs or alterations made by Landlord to the Premises; (d) re¬entry, repossession or reletting of the Premises by Landlord pursuant to this paragraph 5.2; or (e) the appointment of a receiver, upon the initiative of Landlord, to protect Landlord’s interest under this Lease. If Landlord takes any of the foregoing remedial action without terminating this Lease, Landlord may nevertheless at any time after taking any such remedial action terminate this Lease by written notice to Tenant.

5.2.6 Upon the occurrence of an Event of Default and the receipt by Landlord of written notice from Tenant acknowledging the existence of such Event of Default and asking Landlord to attempt to re-let the Premises, Landlord agrees to use reasonable efforts to relet the Premises. Landlord may condition its willingness to attempt to relet the Premises upon Tenant’s delivery to Landlord in advance of Landlord’s attempting to relet the Premises a cash sum equal to Landlord’s reasonable estimate of the Reletting Costs (hereinafter defined) which it will incur in reletting the Premises. Landlord shall not be obligated to attempt to relet the Premises if Landlord then has available for Lease in the Building space of a size which is comparable to the Premises (or the portion thereof that any prospective tenant wishes to lease). Any alterations, decorations, rental concessions, or commissions incurred or provided by Landlord in connection with its reletting of the Premises (the “Reletting Costs”) shall be reasonable and customary in the Arlington, Virginia market for the leasing of comparable space in comparable office buildings, as reasonably determined by Landlord. If Landlord relets the Premises, Landlord shall apply the revenue from such reletting as follows: first, to the payment of any indebtedness of Tenant to Landlord under this Lease other than Base Rent, Additional Rent or any other sums payable by Tenant under this Lease; second, to the payment of any cost of reletting (including finders’ fees and leasing commissions), third, to the payment of the cost of any alterations, improvements, maintenance and repairs to the Premises; and fourth, to the payment of Base Rent, Additional Rent and other sums due and payable and unpaid under this Lease. Landlord shall hold and apply the residue, if any, to payment of future Base Rent, Additional Rent and other sums payable under this Lease as the same become due, and shall deliver the eventual balance, if any, to Tenant. Should revenue from letting during any month, after application pursuant to the foregoing provisions, be less than the sum of the Base Rent, Additional Rent and other sums payable under this Lease and Landlord’s expenditures for the Premises during such month, Tenant shall be obligated to pay such deficiency to Landlord as and when such deficiency arises.

5.2.7 Pursuit of any of the foregoing remedies shall not preclude pursuit of any of the other remedies provided in this Lease or by law (all such remedies being cumulative), nor shall

pursuit of any remedy provided in this Lease constitute a forfeiture or waiver of any Base Rent, Additional Rent or other sum payable under this Lease or of any damages accruing to Landlord by reason of the violation of any of the covenants or conditions contained in this Lease.

5.3 Right to Perform. If Tenant shall fail to pay any sum of money, other than Base Rent or Additional Rent, required to be paid by it under this Lease or shall fail to perform any other act on its part to be performed under this Lease, and such failure shall continue beyond any applicable notice and cure period after notice of such failure by Landlord, or such shorter time if reasonable under the circumstances, Landlord may, but shall not be obligated to, and without waiving or releasing Tenant from any obligations of Tenant, make such payment or perform such other act on Tenant’s part to be made or performed as provided in this Lease. Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of the nonpayment of sums due under this paragraph 5.3 as in the case of default by Tenant in the payment of Base Rent.

5.4 Landlord’s Default. Landlord shall not be in default under this Lease unless Landlord fails to perform material obligations required of Landlord within ten (10) Business Days after written notice is delivered by Tenant to Landlord and to the holder of any mortgages or deeds of trust (collectively, “Lender”) covering the Premises whose name and address shall have theretofore been furnished to Tenant in writing, specifying the obligation which Landlord has failed to perform; provided, however, that if the nature of Landlord’s obligation is such that more than ten (10) Business Days are required for performance, then Landlord shall not be in default if Landlord or Lender commences performance within such ten (10) Business Day period and thereafter diligently prosecutes the same to completion within a reasonable time thereafter. All obligations of Landlord hereunder shall be construed as covenants, not conditions. Except as otherwise expressly set forth in paragraph 5.5, below, Tenant’s exclusive remedy for a default by Landlord shall be either an action for specific performance or an action for actual damages.

5.5 Tenant’s “Self-Help” Rights.

5.5.1 In the event that for reasons not caused by Tenant (or any of its employees or agents) or by a Force Majeure Event, Landlord fails to provide any services or utilities or to perform any repairs or maintenance for the Premises required of Landlord under this Lease, and such failure (i) continues after Landlord has been notified in writing thereof and fails to provide such services or utilities within the prescribed time period (or if no cure period is prescribed, a reasonable period of time after Landlord’s receipt of written notice from Tenant), and (ii) materially impairs Tenant’s use and occupancy of the Premises (collectively, the “Cure Conditions”), then Tenant may deliver written notice (“Cure Notice”) to Landlord (and, if Tenant elects to deliver such notice to Landlord, Tenant must deliver an identical notice to any Mortgagee) stating that Tenant intends to perform such repair or maintenance. Prior to Tenant undertaking any action to cure or remedy such condition, Tenant shall first allow Landlord and any Mortgagee ten (10) Business Days following receipt by Landlord and the Mortgagee of such Cure Notice to attempt to cure or remedy the event or condition specified in Tenant’s notice; provided, however, if such default cannot be cured within said ten (10) Business Day period, this period shall be extended for such longer period as may be reasonably required, but in no event more than an additional sixty (60) Business Days, to permit Landlord or the Mortgagee to effect such cure, provided that Landlord or the Mortgagee commences to cure such default within the

said ten (10) Business Day period and proceeds diligently thereafter to effect such cure (the “Final Cure Period”). If Landlord or the Mortgagee fails to cure or remedy such condition within such Final Cure Period, then Tenant shall give Landlord and the Mortgagee written notice that Tenant will immediately commence to cure or remedy such condition (i.e., perform such repair or maintenance) and three (3) Business Days after delivering such notice Tenant may, subject to the terms and conditions set forth below, take such action that is reasonably necessary to cure or remedy such condition, unless Landlord or the Mortgagee shall have denied, prior to the expiration of such three (3) Business Day-period, that the Cure Conditions have occurred.

5.5.2 In the event that Landlord fails to deny that the Cure Conditions have occurred, Landlord and Tenant shall, within three (3) Business Days after written notice, appoint a mutually agreeable engineer or architect (the “Arbitrator”) to arbitrate and decide the issue, on an expedited basis, of whether the Cure Conditions have occurred. If Landlord and Tenant are unable to agree on an Arbitrator, Landlord and Tenant shall ask the American Arbitration Association to choose an Arbitrator from among the National Panel of Real Estate Industry Arbitrators. If such Arbitrator determines that the Cure Conditions have occurred, then Tenant may take such action that is reasonably necessary to cure or remedy such condition subject to and in accordance with the terms and conditions set forth below; otherwise, Tenant shall not be entitled to undertake any such cure. If the Cure Conditions have occurred and Tenant is entitled hereunder to and does undertake the cure pursuant to the Cure Notice, then upon the completion of such work and the receipt by Tenant of final lien waivers from all contractors, subcontractors and materialmen who performed work or supplied goods in affecting such cure, Tenant shall be permitted to deliver to Landlord an invoice (which shall include all lien waivers) for the reasonable (and competitive) and actual out-of-pocket costs and expenses incurred by Tenant in effecting such cure; and Landlord shall pay to Tenant the amount of such invoice within thirty (30) days after delivery of such invoice (and lien waivers) by Tenant. Notwithstanding the foregoing, it is understood that the Arbitrator’s determination that the Cure Conditions have occurred shall permit Tenant to undertake the cure pursuant to the Cure Notice as provided herein, but shall not be determinative that a default by Landlord has occurred hereunder or for any other purpose. In fulfilling its obligations to notify the Mortgagee before proceeding with any action to cure or remedy any Cure Condition, Tenant may rely upon information most recently provided by Landlord (including that contained in any SNDA) as to the identity and address of any Mortgagee. In no event shall Tenant be entitled to exercise the cure rights set forth in this paragraph 5.5 with respect any of the common areas of the Building or any base Building system or structural components, except with respect to the portion of any base Building systems within the Premises (but only if the work performed by Tenant does not affect any other part of the Building or any services provided to any other part of the Building or occupant of the Building). In addition, Tenant shall not be entitled to exercise the cure rights set forth in this paragraph 5.5 while Tenant is in default under this Lease.

5.5.3 In the event that Tenant seeks to cure or remedy any event or condition which gives rise to Tenant’s cure right set forth in this paragraph 5.5, Tenant shall (a) proceed in accordance with the applicable provisions of this Lease (including without limitation the provisions of paragraphs 4.4 and 4.5 hereof) and all Governmental Laws; (b) use only contractors (i) approved by Landlord, (ii) which satisfy the Contractor Requirements, and (iii) which are duly licensed in the Commonwealth of Virginia and insured; (c) upon commencing such repairs, complete the same within a reasonable period of time, (d) effect such repairs in a

good and workmanlike quality; (e) use new materials; (f) minimize any interference or impact on any other tenants and occupants of the Building; and (g) indemnify and hold Landlord and the Mortgagee harmless from any and all liability, damage and expense arising from injury to persons or personal property arising out of or resulting from Tenant’s exercise of such rights. The provisions of paragraph 4.9, above, shall not apply in the event the Premises or Building is damaged by fire or casualty while Tenant is attempting to cure or remedy any Cure Conditions.

5.5.4 Notwithstanding anything to the contrary set forth in the Lease, Landlord and Tenant expressly acknowledge and agree that: (a) the provisions of this paragraph 5.5 shall not apply in the event that (i) Tenant is not then leasing or occupying at least 42,128 rentable square feet of space in the Building, or (ii) an uncured Event of Default then exists under the Lease; and (b) the rights granted in this paragraph 5.5 are personal to the named Tenant hereunder and may not be exercised by any subtenant or assignee, except for an assignee that is a Qualified Tenant Affiliate.

SECTION 6: MISCELLANEOUS PROVISIONS

6.1 Notices. All notices, demands, consents, approvals, statements and communications required or permitted under this Lease shall be in writing and, if intended for Landlord, shall be addressed to Landlord at the addresses set forth opposite Landlord’s signature; and if intended for Tenant, shall be addressed to Tenant at the address set forth opposite Tenant’s signature, or to such other address as either party may by written notice, given in accordance with this paragraph 6.1, advise the other party. All such communications shall be transmitted by personal delivery, reputable express or courier service, or United States Postal Service, postage prepaid. All such communications shall be deemed delivered and effective on the earlier of (a) the date received or refused for delivery, or (b) five (5) calendar days after having been deposited in the United States Postal Service, postage prepaid. Notwithstanding the means of transmission authorized earlier in this paragraph 6.1, those communications which contain a notice of breach or default, a notice of an event or occurrence that with the passage of time or the giving of notice, or both, would cause a breach or default to arise, or a demand for performance shall be transmitted by one or more of the following methods: (i) United States Postal Service, certified mail, return receipt requested; or (ii) personal delivery, accompanied by a receipt and signed by a representative of the addressee acknowledging delivery on a specified date, with delivery not effective unless the receipt is given, or (iii) reputable express or courier service.

6.2 Attorneys’ Fees and Expenses. In the event that either Landlord or Tenant shall institute any legal action or proceeding against the other relating to the provisions of this Lease or any default hereunder, the unsuccessful party in such action or proceeding agrees to pay to the prevailing party the reasonable attorneys’ fees, expenses and court costs (including those relating to any appeal) actually incurred by the prevailing party.

6.3 No Accord and Satisfaction. No payment by a party or receipt by a party of an amount less than the sum then due and payable under this Lease shall be deemed to be other than a payment on account of such sum which is owing, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed an accord and satisfaction, nor preclude the accepting party’s right to recover the balance of any amount payable or its right to pursue any other remedy provided in this Lease or at law.

6.4 Successors; Joint and Several Liability. Except as provided in the paragraph captioned “Limitation on Recourse” and subject to paragraph 4.16 of this Lease (captioned “Assignment and Subletting by Landlord”), ail of the covenants and conditions contained in this Lease shall apply to and be binding upon Landlord and Tenant and their respective heirs, executors, administrators, successors and assigns. In the event that more than one person, partnership, company, corporation or other entity is included in the term “Tenant”, then each such person, partnership, company, corporation or other entity shall be jointly and severally liable for all obligations of Tenant under this Lease.

6.5 Choice of Law. This Lease shall be construed and governed by the laws of the Commonwealth of Virginia. Tenant and Landlord each consent to the state courts in Arlington, Virginia as the choice of venue for any legal proceeding brought by Landlord or Tenant to enforce the terms of this Lease.

6.6 No Waiver of Remedies. The waiver by a party of any covenant or condition contained in this Lease shall not be deemed to be a waiver of any subsequent breach of such covenant or condition nor shall any custom or practice which may develop between the parties in the administration of this Lease be construed to waive or lessen the rights of the waiving party to insist on the strict performance by the other of all of the covenants and conditions of this Lease. No act or thing done by Landlord or Landlord’s Agents during the Lease Term shall be deemed an acceptance or a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless made in writing and signed by Landlord. The mention in this Lease of any particular remedy shall not preclude a party from any other remedy it might have, either under this Lease or at law, nor shall the waiver of or redress for any violation of any covenant or condition in this Lease or in any of the rules or regulations attached to this Lease or later adopted by Landlord, prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by a party of any other sum payable under this Lease with knowledge of a breach of any covenant or condition in this Lease shall not be deemed a waiver of such breach. The failure of Landlord to enforce any of the rules and regulations attached to this Lease or later adopted, against Tenant or any other tenant in the Building, shall not be deemed a waiver. Any waiver by a party must be in writing and signed by waiving party to be effective.

6.7 Offer to Lease. The submission of this Lease in a draft form to Tenant or its broker or other agent does not constitute an offer to Tenant to lease the Premises. This Lease shall have no force or effect until it is executed and delivered by both Tenant and Landlord.

6.8 Force Majeure Event. In the event that either party shall be delayed, hindered in or prevented from the performance of any act or obligation required under this Lease by reason of acts of God, strikes, lockouts, labor troubles or disputes, inability to procure or shortage of materials or labor, failure of power or utilities, governmental action or inaction, delay in transportation, fire, vandalism, accident, flood, severe weather, other casualty. Governmental Requirements (including mandated changes in the Plans and Specifications or in the Tenant Improvements resulting from changes in pertinent Governmental Requirements or interpretations thereof), riot, insurrection, civil commotion, sabotage, explosion, war, natural or local emergency, acts or omissions of others, including the other party, or other reasons of a similar or dissimilar nature not solely the fault of, or under the exclusive control of, Landlord or Tenant, as

applicable (the “Force Majeure Events”), then performance of such act or obligation (other than Tenant’s rental obligations under this Lease) shall be excused for the period of the delay and the period for the performance of any such act or obligation shall be extended for the period equivalent to the period of such delay.

6.9 Severability; Captions. If any clause or provision of this Lease is determined to be illegal, invalid, or unenforceable under present or future laws, the remainder of this Lease shall not be affected by such determination, and in lieu of each clause or provision that is determined to be illegal, invalid or unenforceable, there be added as a part of this Lease a clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be possible and be legal, valid and enforceable. Headings or captions in this Lease are added as a matter of convenience only and in no way define, limit or otherwise affect the construction or interpretation of this Lease.

6.10 Interpretation. Whenever a provision of this Lease uses the term (a) “include” or “including”, that term shall not be limiting but shall be construed as illustrative, (b) “covenant”, that term shall include any covenant, agreement, term or provision, (c) “at law”, that term shall mean as specified in any applicable statute, ordinance or regulation having the force of law or as determined at law or in equity, or both, and (d) “day”, that uncapitalized word shall mean a calendar day. This Lease shall be given a fair and reasonable interpretation of the words contained in it without any weight being given to whether a provision was drafted by one party or its counsel.

6.11 Incorporation of Prior Agreement; Amendments. This Lease contains all of the agreements of the parties to this Lease with respect to any matter covered or mentioned in this Lease, and no prior agreement or understanding pertaining to any such matter shall be effective for any purpose. No provision of this Lease may be amended or added to except by an agreement in writing signed by the parties to this Lease or their respective successors in interest.

6.12 Authority.

6.18 Option to Extend.

6.18.1 Tenant shall have and is hereby granted the option to extend the Lease Term hereof for one (1) additional period of five (5) years (the “Extension Period”), provided that (i) Tenant gives written notice to Landlord of Tenant’s irrevocable exercise of such extension option (the “Renewal Notice”) no later than twelve (12), months prior to the expiration of the Lease Term; (ii) no Event of Default remains uncured at the time of the exercise by Tenant of its extension option; (iii) no Event of Default exists at the commencement of the Extension Period; and (iv) Tenant has not assigned its interest in this Lease or sublet more than twenty percent (20%) of the Premises, except as part of a Permitted Transfer or to a Qualified Tenant Affiliate.

6.18.2 All terms and conditions of this Lease, including without limitation all provisions governing the payment of Additional Rent and annual increases in Base Rent, shall remain in full force and effect during the Extension Period, provided that (i) Base Rent payable during the Extension Period shall equal one hundred percent (100%) of the then-current Fair Market Rental Rate (hereinafter defined) at the time of the commencement of the Extension Period; (ii) Landlord shall not be obligated to make any improvements or alterations in or to the Premises; and (iii) Landlord shall provide standard “market” tenant concessions (including improvement allowance, rental abatement and brokerage commissions) then being provided to tenants renewing leases of similar space (including size, build-out and condition), in similar buildings for similar length terms. 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 renewal for comparable space as to location of floor(s) (i.e. upper floors or lower level floors), size and use, in a comparable building as to quality, condition and age which is located in the Arlington, Virginia area, with a comparable build-out and a comparable length lease 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 the tenant with standard “market” tenant concessions for renewal transactions (including a tenant improvement allowance); and (C) the tenant will continue to pay Tenant’s Pro Rata Share (Operating Costs) of increases in Operating Costs and Tenant’s Pro Rata Share (Property Taxes) of increases in Property Taxes in accordance with the terms of this Lease, using the New Base Year (hereinafter defined) as the “Base Year” (as such term is defined in subsection 3.4.6, above) under Section 3.4 of this Lease. As used herein, the term “New Base Year” shall mean the calendar year in which the first day of the Extension Period occurs; provided, however, if the Extension Period commences during the months of October, November or December of any calendar year, the New Base Year shall be the calendar year immediately following the calendar year in which the Extension Period commences.

6.18.3 Landlord and Tenant shall negotiate in good faith to determine the Base Rent for the Extension Period, for a period (the “Negotiation Period”) commencing on the later of: (a) forty-five (45) days after Landlord’s receipt of the Renewal Notice; or (b) the date which is fifteen (15) months prior to the first day of the Extension Period. In the event Landlord and Tenant are unable to agree upon the Base Rent and other economic terms for the Extension Period within the Negotiation Period, the Fair Market Rental Rate shall be determined by a board of three (3) licensed real estate brokers, one of whom shall be named by Landlord, one of whom shall be named by Tenant, and the two so appointed shall select a third. Each real estate broker so selected shall be licensed in the Commonwealth of Virginia specializing in the field of commercial office leasing, having no less than ten (10) years’ of continuous experience in such field, and recognized as experienced in the Arlington, Virginia market, ethical and reputable within the field. Landlord and Tenant agree to make their appointments promptly within ten (10) Business Days after the expiration of the Negotiation Period, or sooner if mutually agreed upon. The two (2) brokers selected by Landlord and Tenant shall promptly select a third broker within ten (10) days after they both have been appointed, and each broker, within fifteen (15) days after the third broker is selected, shall submit his or her determination of the Fair Market Rental Rate. The Fair Market Rental Rate shall be the mean of the two closest rental rate determinations. 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. In the event that either party fails timely to select its broker, or if the broker selected by Landlord or Tenant fails timely to deliver his or her determination of Fair Market Rental Rate, the Fair Market Rental Rate shall be determined by the broker of the party which has complied with the terms of this subparagraph 6.18.3.

6.18.4 Should the Lease Term be extended hereunder, Tenant shall execute an amendment modifying this Lease within fifteen (15) Business Days after Landlord presents to Tenant the amendment document as reasonably agreed to by Landlord and Tenant, which agreement shall set forth, inter alia, the monthly installments of Base Rent and other economic terms for the Extension Period. Should Tenant fail to execute a commercially reasonable amendment (which accurately sets forth such information and which contains no material provisions inconsistent with the terms hereof) within ten (10) Business Days after presentation of

same by Landlord, time being of the essence, Landlord may notify Tenant in writing of such failure (the “Amendment Notice”). In the event that Tenant fails to execute and deliver to Landlord the amendment within five (5) Business Days after Landlord’s delivery to Tenant of the Amendment Notice, Tenant’s right extend the Lease Term 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.

6.18.5 In the event the final determination of the Fair Market Rental Rate shall not be made on or before the first day of the Extension Period in accordance with the provisions of this paragraph 6.18, then pending such final determination. Tenant shall continue to pay Base Rent and Additional Rent at the same Base Rent and Additional Rent amounts then payable by Tenant during the last month of the original Lease Term. If, based upon the final determination of the brokers or the agreement of the parties, such payments made by Tenant on account of Base Rent and Additional Rent for such portion of the Extension Period differ from the Base Rent and Additional Rent which should have been paid by Tenant during that portion of the Extension Period, the parties shall adjust such amount by a cash payment within ten (10) Business Days of such determination.

6.19 Right of First Offer.

6.19.1 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 ROFO Space (hereinafter defined) or any portion thereof existing as of the date of this Lease, (ii) any renewal rights granted by Landlord after the date of this Lease to any tenant of all or any portion of the ROFO Space, and (iii) the right of any tenant of the ROFO 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 is hereby granted the following expansion rights during the initial Lease Term with respect to the ROFO Space. As used herein, the term “ROFO Space” shall mean any space located on the fifth (5^th) and sixth (6^th) floors of the Building, but only after the expiration of the term of a New Lease (hereinafter defined) demising all or any portion of such space. As used herein, the term “New Lease” means a lease of any portion of the ROFO Space between Landlord and any third party, which lease is entered into after the Effective Date. Notwithstanding any provision of this Lease to the contrary, Tenant shall have no rights with respect to the ROFO 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 paragraph 6.19.

6.19.2 In the event that any ROFO Space becomes or is reasonably anticipated by Landlord to become vacant following Landlord’s initial lease-up of such ROFO Space, then, except as provided below, Landlord shall notify Tenant in writing (the “Availability Notice”) of the availability of the ROFO Space in question (the “Available ROFO Space”), and set forth in such Availability Notice: (i) the Base Rent to be paid by Tenant with respect to the Available ROFO Space, which Base Rent shall be comparable to the base rental rates then being offered to tenants entering into leases of comparable space as to location, configuration, build-out and size, in a comparable building as to quality, age and condition which is located in the Arlington, Virginia area, having a comparable term (the “Fair Market ROFO Rental Rate”); (ii) the other terms and conditions pursuant to which Landlord would lease the available ROFO Space to Tenant, including a “market” tenant improvement allowance and period of rent abatement; and

(iii) the date on which Landlord anticipates that the Available ROFO Space will be available for delivery to Tenant (the “Availability Date”). Provided that (A) no uncured Event of Default then exists under this Lease; (B) Tenant has not assigned its interest in this Lease or sublet more than twenty percent (20%) of the Premises, except to a Qualified Tenant Affiliate; (C) not less than thirty-six (36) months will remain in the Lease Term as of the Availability Date; and (D) Tenant notifies Landlord, in writing, within ten (10) business days after Tenant’s receipt of the Availability Notice, time being of the essence, of Tenant’s election to lease all (but not less than all) of the Available ROFO Space (the “Tenant Election Notice”). Tenant shall have the right to lease the Available ROFO Space on the terms and conditions hereinafter set forth. The term of demise of the Available ROFO Space shall commence on the date on which Landlord delivers the Available ROFO Space to Tenant, and shall end on the last day of the Lease Term (the “ROFO Term”).

6.19.3 In the event that Tenant timely delivers a Tenant Election Notice to Landlord, but fails to specify in such notice that Tenant disagrees with the Fair Market ROFO Rental Rate set forth in the Availability Notice: (i) the Fair Market ROFO Rental Rate set forth in the Availability Notice delivered by Landlord shall be deemed to be the Fair Market ROFO Rental Rate for purposes of this paragraph 6.19; and (ii) the terms of the ROFO Amendment (hereinafter defined) shall be based on the terms set forth in (he Availability Notice. In the event that Tenant states in the Tenant Election Notice that Tenant disagrees with Landlord’s determination of the Fair Market ROFO Rental Rate set forth in the Availability Notice, and Tenant specifies in such Tenant Election Notice: (A) Tenant’s calculation of the Fair Market ROFO Rental Rate, and (B) comparable lease data confirming Tenant’s calculation of the Fair Market ROFO Rental Rate, Landlord and Tenant shall negotiate in good faith to determine the Fair Market ROFO Rental Rate for a period of thirty (30) days after the date on which Landlord receives the Tenant Election Notice (the “ROFO Negotiation Period”) to attempt to arrive at a mutually agreeable Fair Market ROFO Rental Rate. In the event that Landlord and Tenant are unable to agree upon the Fair Market ROFO Rental Rate within the ROFO Negotiation Period, then the Fair Market ROFO Rental Rate shall be determined in accordance with three-broker method procedure set forth in paragraph 6.18, above, with respect to the Fair Market Rental Rate, provided that the Base Rent payable during the ROFO Term shall be based on the Fair Market ROFO Rental Rate.

6.19.4 In the event that Tenant timely delivers a Tenant Election Notice, Landlord and Tenant shall execute and deliver an amendment to this Lease (the “ROFO Amendment”) incorporating the Available ROFO Space, which ROFO Amendment shall set forth, among other things: (A) the amount of Base Rent and the Additional Rent attributable to the Available ROFO Space; and (B) the adjustment to Tenant’s Pro Rata Share (Operating Costs) and Tenant’s Pro Rata Share (Property Taxes) resulting from the demise of the Available ROFO Space hereunder. In the event that Tenant does not execute the ROFO Amendment (which amendment accurately sets forth the terms and conditions relating to the demise of the ROFO Space to Tenant, as set forth in this paragraph 6.19) within ten (10) Business Days after receipt thereof from Landlord, time being of the essence, then Tenant’s right of first offer to lease the Available ROFO Space shall be null and void and of no further force or effect and Landlord may lease the Available ROFO Space to any person or entity of its choice on whatever terms and conditions Landlord elects in its sole discretion.

6.19.5 In the event Landlord and Tenant execute the ROFO Amendment, and Landlord is unable to deliver possession of the Available ROFO Space to Tenant on the Availability Date 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. In such event, Landlord shall use reasonable efforts to make the Available ROFO Space available to Tenant as soon as reasonably practicable after the Availability Date.

6.20 Tenant’s Termination Option.

6.20.1 Provided that (a) no Event of Default exists at the time Tenant delivers a Termination Notice (hereinafter defined) to Landlord, and (b) no uncured Event of Default exists on the Termination Date (hereinafter defined), Tenant shall have the one time option to terminate this Lease (the “Termination Option”) effective as of the last day of the thirty-sixth (36^th) full calendar month following the Rent Commencement Date (the “Termination Date”), subject to the terms and conditions set forth in this paragraph 6.20. Tenant may exercise its Termination Option solely by delivering to Landlord, on or before the date which is at least twelve (12) months prior to the Termination Date, irrevocable written notice of termination {the “Termination Notice”) on or before the date. In order to exercise the Termination Option, Tenant must pay to Landlord, at the time Tenant delivers the Termination Notice to Landlord, a termination payment {the “Termination Payment”) equal to sum of (i) two (2) monthly installments of Base Rent payable by Tenant as of the date on which Tenant delivers the Termination Notice to Landlord, plus (ii) the unamortized balance, as of the Termination Date, of all Lease Costs (hereinafter defined). As used in this Lease, the term “Lease Costs” means the sum of: (1) all brokerage commissions incurred by Landlord in connection with this Lease; (2) the Tenant Improvement Allowance; (3) the amount of the Rent Abatement Amount (hereinafter defined); and (4) Landlord’s documented and reasonable attorneys’ fees in connection with the negotiation and drafting of this Lease (not to exceed $15,000.00). As used herein, the term “Rent Abatement Amount” means the sum of the aggregate value of all unpaid Base Rent which was abated by Landlord during the period between the Commencement Date and the Rent Commencement Date based on the amount of Base Rent payable by Tenant as of the Rent Commencement Date. The amortization of the Lease Costs shall be effected as though the total of such costs was the principal amount of a promissory note, bearing interest at the rate of eight percent (8%) per annum, where the principal (and all interest thereon) shall be repaid (commencing on the Commencement Date) in equal monthly installments of principal and interest in such amount as to cause the principal balance to be reduced to zero as of the last day of the sixty-third (63rd) full calendar month of the Lease Term. Tenant shall pay to Landlord the Termination Payment simultaneously with Tenant’s delivery of the Termination Notice. The Termination Payment shall be in addition to, and not in lieu of, the payments of Base Rent, Additional Rent and other charges accruing hereunder through the Termination Date. The Termination Option may not be exercised by any sublessee of all or any portion of the Premises. Time shall be of the essence with respect to Tenant’s delivery to Landlord of the Termination Notice and the Termination Payment. In the event Tenant fails to deliver the Termination Notice or fails to pay the Termination Payment within the time period set forth above, then, at Landlord’s sole option, the Termination Notice may be deemed void and of no further force or effect, and the Lease shall continue in full force and effect.

6.20.2 Should Tenant deliver a Termination Notice and fail to surrender the Premises to Landlord on or before the Termination Date, time being of the essence, then, at Landlord’s sole option: (i) Landlord shall be entitled to exercise all of the rights and remedies available to Landlord under the Lease upon an Event of Default by Tenant pursuant to paragraph 5.2 of this Lease (and such other rights and remedies as may be available to Landlord under the Lease, at law or equity); (ii) Tenant shall be liable to Landlord as a hold-over tenant under the Lease and shall be subject to the terms and conditions of paragraph 3.6 of this Lease; and (iii) Landlord may, by written notice to Tenant (the “Termination Holdover Notice”), inform Tenant that it has remained in the Premises after the Termination Date and that if Tenant fails to vacate the Premises within thirty (30) days after Landlord’s delivery of the Termination Holdover Notice, Landlord may declare the Termination Notice to be null and void. In the event that Tenant fails to vacate the Premises within thirty (30) days after Landlord’s delivery to Tenant of the Termination Holdover Notice, Landlord may, but shall not be obligated to, declare the Termination Notice to be null and void and of no further force or effect and this Lease shall continue in full force and effect, in which event Landlord shall return the Termination Payment to Tenant and all rights of Tenant under this paragraph 6.20 shall immediately lapse and be of no further force or effect. Except in the event Landlord declares the Termination Notice to be null and void, Tenant shall indemnify and hold harmless Landlord from and against any and all reasonable, actual and documented costs, expenses, liabilities and damages (including reasonable attorneys’ fees) resulting from Tenant’s holding over in the Premises for a period in excess of thirty (30) days after the Termination Date, including but not limited to any costs, expenses, liabilities or damages resulting from (A) Landlord’s failure to deliver the Premises to a prospective tenant; and (B) Landlord’s removal from the Premises of any of Tenant’s equipment, furniture or personal property in order to deliver possession of the Premises to a prospective tenant.
