In consideration of the agreements contained herein, Landlord hereby leases the Building to Tenant, and Tenant hereby leases the Building from Landlord, for the Term and upon the terms and conditions hereinafter provided. It is specifically understood that the rentable area of the Building has been determined by the Building's Architect according to the Building Owners and Managers Association International Standard Method for Measuring Floor Space in Office Buildings (1996) (the "BOMA Method"), that Tenant was given the opportunity to verify this determination prior to the Date of Lease, and that the rentable area of the Building for all purposes under this Lease shall be as set forth in Section 1.1. Unless and until otherwise determined in accordance with the next sentence, the rentable area of Building II shall be deemed to be the rentable area set forth in Section 1.2. Upon substantial completion of Building II, the rentable area of Building II will be determined by the Building's Architect according to the BOMA Method, will be confirmed in writing to Tenant, and will be subject to verification by Tenant's Architect, at Tenant's sole expense, within thirty (30) days thereafter. In the event that the measurement by the Building's Architect, as may be verified by Tenant's 8 Architect, shall result in a determination by the parties that the rentable area of Building II is more or less than the rentable area set forth in Section 1.2, Tenant's Proportionate Share shall be adjusted in accordance with Section 1.11 using the corrected measurement. In the event there shall occur during the Term any permanent increase or decrease to the rentable area of either the Building or Building II, Tenants' Proportionate Share shall be appropriately adjusted as of the date of substantial completion of such change. 3.2. Common Rights. As an appurtenance to the Building, Tenant shall have the non-exclusive right, together with other tenants and occupants of the Corporate Park, to use the Common Area. Landlord shall retain absolute dominion and control over the Common Area and shall operate and maintain the Common Area in such matter as Landlord, in its reasonable discretion, shall determine; provided, however, that such exclusive right shall not operate to impair or impede in any material and adverse manner Tenant's use of the Building for the Permitted Use or Tenant's use of the Common Area for its intended purposes. In no event shall any modification of the Common Area result in a reduction of parking spaces within that portion of the Common Area cross-hatched on Exhibit A-1 (the "Tenant Protected Area") to less than seventy-eight (78) spaces. Landlord expressly reserves the right permanently to change, modify, or eliminate, or temporarily to close, any portion of the Common Area so long as such action does not unreasonably interfere with Tenant's use or enjoyment of the Building or reduce the number of parking spaces within the Tenant Protected Area as above provided. Tenant recognizes, however, that short-term disruptions of parking within the Tenant Protected Area may occur while Building II is being constructed or the Parking Facilities are being repaired and that such disruptions shall not be deemed to be a violation of the terms of this Section 3.2. During the period of any such disruption, there shall be available to Tenant alternative parking within the Common Area in reasonable proximity to the Building. The Building is leased subject to, and Tenant agrees not to violate, (i) the existing easements, covenants, conditions, restrictions, and other matters of record which affect the Building or the Land as of the Date of Lease, as set forth on Exhibit C attached to and made, a part of this Lease ("Existing Title Matters"), or (ii) any additional easements, covenants, conditions, restrictions, and other matters of record which may affect the Building or the Land in the future ("Future Title Matters"), provided that none of the Future Title Matters shall materially and adversely affect Tenant's use of the Building for the Permitted Use or use of the Common Area for parking and access. The Existing Title Matters and Future Title Matters are sometimes collectively referred to in this Lease as the "Permitted Exceptions". 3.3 Landlord's Reservations. In addition to the other rights of Landlord under this Lease, Landlord reserves the right (i) to change the street address of the Building provided written notice thereof is given to Tenant not later than sixty (60) days prior to the Commencement Date, (ii) to install, erect, use, maintain and repair mains, pipes, conduits and other such facilities in and through Tenant's premises to serve other tenants and occupants of the Building if, in the future, this Lease is terminated by agreement of the parties as to a portion of the Building and Tenant is no longer the sole tenant of the Building, (iii) subject to Tenant's rights hereunder, to control the use of the roof and exterior walls of the Building for any purpose, recognizing that, except as provided in Article XVI, in no event shall Landlord install, affix or otherwise place, or permit any others to place, any exterior signage, advertisements or notices of any sort on such Building, it being the intent of the parties that Tenant alone shall have sole signage rights on or at the Building, subject to Article XIV, (iv) to re-subdivide or establish a 9 condominium regime for the Land, and (v) to use Tenant's name in promotional materials relating to the Corporate Park. Subject to Tenant's right of quiet enjoyment, Landlord may exercise any or all of the foregoing rights without being deemed to be guilty of an eviction, actual or constructive, or a disturbance or interruption of Tenant's business or Tenant's use or occupancy of the Building. ARTICLE IV TERM 4.1. Term. The Term shall commence on the Commencement Date and expire at midnight on the Expiration Date. In the event that the Commencement Date occurs on other than the first day of a month, the Expiration Date shall be extended so as to be the last day of the month in which the Expiration Date occurs. If requested by Landlord, Tenant shall, within five (5) business days of such request, sign a declaration acknowledging the Commencement Date and the Expiration Date. From the Date of Lease until the Commencement Date, all of the terms of this Lease shall be in full force and effect, except that Basic Rent and other amounts due from Tenant shall not be payable with respect to the period preceding the Commencement Date. 4.2. Renewal Option. (i) Tenant shall have one (1) option (the "Renewal Option") to extend the Term for an additional five (5) year period (the "Renewal Period"). The Renewal Option shall be exercised, if at all, strictly in accordance with this Section 4.2 and such exercise shall be effective only if no Event of Default shall exist at the time of exercise or at the time of commencement of the Renewal Period. The Renewal Option shall be exercisable only by written notice given by Tenant to Landlord at least twelve (12) months prior to the expiration of the Term. In the event that Tenant does not timely exercise the Renewal Option, the Renewal Option shall be null and void and of no further force or effect. As used in this Lease, "Term" shall mean the initial Term and, if the Renewal Option is properly exercised in accordance with this Section 4.2, the Renewal Period. (ii) If Tenant properly exercises the Renewal Option, all terms and conditions of this Lease shall be applicable during the Renewal Period, except that (a) no further Renewal Options may be exercised under this Lease, (b) Tenant shall not be entitled again to any of the rental abatements, rental credits, or tenant allowances once provided under this Lease (but market rental concessions shall be taken into account in determining "Prevailing Market Rent" as provided below), and (c) the Basic Rent during the first Lease Year of the Renewal Period shall be the greater of (1) the Basic Rent applicable during the last Lease Year of the Term then expiring, increased in accordance with Section 1.8, or (2) the then "Prevailing Market Rent". The Prevailing Market Rent shall be the triple net rent which is being asked of tenants for office/R and D space comparable to the Building under five (5) year leases in similar buildings in the Gaithersburg, Maryland area as of the date the brokers make their determinations under Section 4.2(iii), taking into account the value of brokerage commissions, rental abatements, rental credits, and tenant allowances, if any, typically being offered or paid under such leases. (iii) If Tenant exercises the Renewal Option, Landlord and Tenant shall endeavor in good faith to agree on the Prevailing Market Rent. If, however, they are unable to 10 do so within thirty (30) days, Tenant shall notify Landlord of the name and address of a leasing broker selected by Tenant to determine the Prevailing Market Rent. Within ten (10) days after receipt of Tenant's notice, Landlord shall notify Tenant in writing of the name and address of a leasing broker selected by Landlord to determine the Prevailing Market Rent. Each broker shall independently make his or her determination of the Prevailing Market Rent within thirty (30) days after the appointment of Landlord's broker. The Prevailing Market Rent shall be deemed to be the average of the two determinations unless the higher of such determinations is greater than one hundred five percent (105%) of the lower of the determinations. If the higher determination is greater than one hundred five percent (105%) of the lower determination, the brokers selected by Landlord and Tenant shall together select a third broker within ten (10) days after rendering their determinations. The third broker shall have twenty (20) days to make his or her determination of the Prevailing Market Rent and upon such determination, the Prevailing Market Rent shall be deemed to be the median determination made by the three (3) brokers. (iv) Each broker appointed pursuant to this Section shall be a disinterested broker licensed in the State of Maryland having recognized competence in the field of commercial leasing and a minimum of ten (10) years experience as a commercial leasing broker or agent in Montgomery County, Maryland. Each party shall pay for the consulting fee of the broker which it selects and the parties shall share equally the consulting fees of the third broker, if any. (v) Beginning with the second Lease Year of the Renewal Period and continuing in each subsequent Lease Year of the Renewal Period, Basic Rent shall increase in the manner provided in Section 1.8. If, however, Basic Rent for the first Lease Year of the Renewal Period is determined on the basis of Prevailing Market Rent, the escalation factor that shall apply to Basic Rent over the balance of the Renewal Period shall be determined as part of the determination of Prevailing Market Rent. ARTICLE V RENT 5.1. Basic Tenant. Tenant shall pay to Landlord the Basic Rent as specified in Section 1.7, escalated in accordance with Section 1.8. 5.2. Payment of Basic Rent. Throughout the Term, Basic Rent for each Lease Year shall be payable in twelve (12) equal monthly installments, in advance, without demand, notice, deduction, offset, recoupment or counterclaim (except as otherwise expressly provided in this Lease), on or before the first day of each and every calendar month during the Lease Year; provided, however, that if the Commencement Date occurs on a date other than on the first day of a calendar month, Basic Rent shall be pro rated on a per diem basis for the period from the Commencement Date through the last day of such calendar month at the rate payable for the first Lease Year and shall be due and payable on the Commencement Date. Tenant shall pay the Basic Rent and all Additional Rent, by good check or in lawful currency of the United States of America, to Landlord at Landlord's Address, or to such other address or in such other manner as Landlord from time to time specifies by written notice to Tenant. Any payment made by Tenant to Landlord on account of Basic Rent may be credited by Landlord to the payment of any late 11 charges then due and payable and to any Basic or Additional Rent then past due before being credited to Basic Rent currently due. 5.3. Additional Rent. All sums payable by Tenant under this Lease, other than Basic Rent, shall be deemed "Additional Rent", and, unless otherwise set forth herein, shall be payable in the same manner as set forth above for Basic Rent. 5.4. Net Lease. Except as otherwise expressly provided in this Lease, Tenant shall pay all Real Estate Taxes, all water, sewer, and other utility charges and assessments, all maintenance, repair and replacement costs (excluding any costs of structural repairs which Landlord is obligated to bear under this Lease and any items required to be excluded from CAM Costs or Real Estate Taxes under the terms of this Lease), all fire protection and security costs, and all other expenses of every kind and character, whether foreseen or unforeseen, ordinary or extraordinary, which either Landlord or Tenant becomes liable to pay due to its estate or interest in the Building, or which arise out of the possession, use, occupancy, operation, maintenance or repair of all or any portion of the Building. ARTICLE VI SECURITY DEPOSIT 6.1. Letter of Credit. Simultaneously with the execution of this Lease, Tenant shall deliver the Security Deposit to Landlord. The Security Deposit shall consist of an irrevocable letter of credit substantially in the form of Exhibit D attached to and made a part of this Lease (the "Letter of Credit"). The Letter of Credit shall be issued by either Allfirst Bank or such other federally insured bank with branches in the Washington, D.C. metropolitan area which is reasonably acceptable to Landlord and shall be transferable by Landlord. Subject to the reductions set forth below, the Letter of Credit shall be maintained in full force and effect by Tenant throughout the Term until returned to Tenant for cancellation. The Security Deposit shall be held by Landlord, without obligation for interest, as security for the performance of Tenant's obligations and covenants under this Lease. It is expressly understood and agreed that the Security Deposit is not an advance rental deposit or a measure of Landlord's damages in case of an Event of Default. If an Event of Default shall occur or if Tenant fails to surrender the Building in the condition required by this Lease, Landlord shall have the right (but not the obligation), and without prejudice to any other remedy which Landlord may have on account thereof, to draw upon and use all or any portion of the Security Deposit to cure the default or remedy the condition of the Building. In the event any portion of the Security Deposit has been so used by Landlord during the Term, Tenant shall restore the Security Deposit to its full original amount within ten (10) days after Landlord has drawn upon the Security Deposit. If at any time prior to the return of the Security Deposit to Tenant either (a) Tenant fails to renew the Letter of Credit for a one (1) year period at least thirty (30) days prior to its then current expiration date, or (b) Landlord receives written notice from the issuer of the Letter of Credit that such issuer does not intend to renew the Letter of Credit for another one (1) year period, Landlord may draw upon the Letter of Credit to its full outstanding amount and the proceeds of such draw shall thereafter constitute the Security Deposit. If Landlord shall sell or transfer its interest in the Building, Landlord shall transfer the Security Deposit to the purchaser or transferee, in which event Tenant shall look solely to such purchaser or transferee for the return of the Security Deposit and Landlord shall be released from all liability to Tenant for the return of the Security Deposit. 12 Tenant, upon request by Landlord, shall cooperate with Landlord and execute any documents which may be required to effectuate the transfer of the Security Deposit to any purchaser, transferee, or Mortgagee of the Building. Any remaining balance of the Security Deposit shall be returned to Tenant at the later of (i) thirty (30) days after the Expiration Date or earlier termination of this Lease or (ii) the fulfillment of all of Tenant's obligations under this Lease following the Expiration Date or earlier termination of this Lease. 6.2. Reduction of Letter of Credit. Notwithstanding the foregoing, the Security Deposit shall be reduced to One Hundred Seventy-Five Thousand Dollars ($175,000.00) as of the first day of the fourth Lease Year and to Seventy-Three Thousand Four Hundred Forty-Four Dollars ($73,444.00) as of the first day of the ninth Lease Year, provided that, at the time for reduction, no Event of Default exists and no event has occurred and is continuing which would constitute an Event of Default with the giving of notice or the passage of time or both. Each reduction shall be effectuated by Tenant obtaining and furnishing to Landlord, as of the time for reduction, an amendment of the Letter of Credit appropriately reducing the amount of the Letter of Credit. If required by the issuer of the Letter of Credit, Landlord shall confirm in writing its consent to such amendment, provided that the conditions for reduction set forth above are satisfied. Except as expressly provided in this Article, the Security Deposit shall not be reduced. 6.3. Increase of Letter of Credit. Notwithstanding anything contained in this Article, the Security Deposit shall be subject to increase, and the reduction provisions of Section 6.2 shall not apply, to the extent set forth in Section 11.1. ARTICLE VII CAM COSTS 7.1. Tenant's Proportionate Share. Commencing with the first Lease Year and during each Lease Year of the Term thereafter, Tenant shall pay to Landlord, as Additional Rent, Tenant's Proportionate Share of the CAM Costs incurred during each Calendar Year. 7.2. CAM Costs Defined. As used herein, the term "CAM Costs" shall mean all expenses and costs of every kind and nature which Landlord incurs because of or in connection with the ownership, maintenance, repair, management and operation of the Land and Common Area, subject to the exceptions set forth below. CAM Costs shall include, without limitation, all costs, expenses and disbursements incurred or made in connection with the following: (i) Wages and salaries of all employees up to and including the grade of chief engineer, whether employed by Landlord or the Corporate Park's management company, engaged in the operation and maintenance or security of the Land and the Common Area (except that if any such employee is not employed full-time in connection with providing such services to the Corporate Park, such wages and/or salaries shall be pro rated proportionally to reflect the percentage of time such employee is engaged in work related to the Corporate Park), and all costs related to or associated with such employees or the carrying out of their duties, including uniforms and their cleaning, taxes, insurance and benefits; 13 (ii) All supplies and materials used directly in the operation and maintenance of the Land and the Common Area; (iii) All utilities serving the Land or the Common Area; (iv) All maintenance, operation and service agreements for the Land and the Common Area and any equipment related thereto, including, without limitation, service and/or maintenance agreements for security, groundskeeping, landscaping and exterior plant maintenance; (v) All repairs and replacements to the Land and the Common Area (excluding amounts paid for by proceeds of insurance or by Tenant or other third parties other than as a part of the CAM Costs), regardless of whether foreseen or unforeseen; (vi) All operation and maintenance of the Land and the Common Area, including, without limitation, ice and snow removal, landscaping, groundskeeping, sweeping and trash removal, maintenance of entry features and directional signage, patching, re-striping, and resurfacing of roads, driveways and parking lots, and lighting of the Common Area; (vii) Accounting and legal fees incurred in connection with the operation and maintenance of the Corporate Park, excluding attorneys' fees and other expenses incurred in connection with leasing space in the Corporate Park or with negotiations or disputes with tenants, brokers, adjoining parties, other occupants, or prospective tenants or occupants of the Corporate Park; (viii) Any additional services not provided to tenants of the Corporate Park at the Commencement Date but thereafter provided by Landlord as Landlord shall deem necessary or desirable in connection with the management or operation of the Land and the Common Area, provided that the additional services are customarily furnished by landlords in similar office and R and D complexes in Montgomery County, Maryland; (ix) All community association dues and all assessments, whether general, special or otherwise, levied against Landlord or the Corporate Park pursuant to any declaration or other instrument affecting the Corporate Park, subject to the limitations on the costs of capital improvements set forth below; (x) Any capital improvements (including, without limitation, replacements) made to the Land or Common Area after the Commencement Date which are primarily installed for the purpose of reducing CAM Costs (as opposed to those installed because of the obsolescence of the item being replaced or the recognition that such item has reached the end of its useful life) or are required or imposed by any law or governmental rule, regulation, or requirement that was not applicable to the Land or the Corporate Park at the time the Corporate Park was constructed (each a "Permitted Capital Improvement"). The cost of each Permitted Capital Improvement shall be amortized over the useful life of that improvement consistent with generally accepted accounting principles consistently applied ("GAAP"), together with interest on the unamortized balance of such cost at the Interest Rate or such higher rate as may have been paid by Landlord on funds borrowed for the purposes of constructing or installing the Permitted 14 Capital Improvement, to the extent that such higher rate is consistent with then prevailing market interest rates; (xi) Other expenses and costs reasonably necessary for operating and maintaining the Land and the Common Area. 7.3 Exclusions from CAM Costs. Notwithstanding Section 7.2, CAM Costs shall not include any of the following: (i) depreciation or expenses for capital improvements made to the Land or Corporate Park, other than Permitted Capital Improvements; (ii) costs of repairs, restoration, replacements or other work occasioned by either (a) fire, windstorm or other casualty coverable by the property insurance required to be maintained by Landlord under Section 17.5, (whether such destruction be total or partial), provided, however, that up to Ten Thousand Dollars ($10,000.00) of the costs of such repairs and restoration may be included in CAM Costs to the extent such costs are payable by Landlord pursuant to the deductible under its property insurance, (b) the exercise by governmental authorities of the right of eminent domain, whether such taking be total or partial, or (c) the negligence or intentional tort of Landlord, or any subsidiary or affiliate of Landlord, or any representative, employee or agent of same;

(vi) costs, fines, interest, penalties, legal fees or costs of litigation incurred due to Landlord's late payment of taxes, utility bills and other costs (or late filing of tax returns or other informational returns or reports), unless caused by late payment of Rent and other amounts by Tenant under this Lease (or, in the case of tax or informational returns or reports, Tenant's failure or delay in furnishing to Landlord information relative to Tenant required for the filing of the returns); (vii) costs incurred for any item covered by a manufacturer's, materialman's, vendor's or contractor's warranty (a "Warranty") to the extent that proceeds under the Warranty are paid to Landlord for such item (but costs of obtaining recovery under the Warranty shall be included as part of CAM Costs); (viii) income, excess profits, franchise taxes or other such taxes imposed on or measured by the income of Landlord from the operation of the Corporate Park; (ix) costs of Landlord's defense of lawsuits against Landlord and any judgments or costs of settlement resulting from such lawsuits (but this exclusion shall not be deemed to limit in any way any indemnification by Tenant provided for in this Lease);

(xv) consulting costs and expenses paid by Landlord, except those involving maintenance, repair, or improvement of the Common Area or Building; (xvi) any cost incurred in connection with the investigation or remediation of any Hazardous Material (as defined in Section 26.1) located in, on, under or about the Corporate Park as of the Date of Lease or any 15 Hazardous Material stored, used or released by Landlord, its employees, agents, licensees, or tenants after the Date of Lease, and any cost incurred in connection with any government investigation, order, proceeding or report with respect thereto (unless such substances were introduced in the Building or Corporate Park by Tenant, its invitees or guests); (xvii) costs or fees incurred in connection with a sale, lease or transfer (including testamentary transfers) of all or any part of the Corporate Park or any interest therein, or of any interest in Landlord, or in any person comprising, directly or indirectly, Landlord or in any person having an equity interest, directly or indirectly in Landlord; (xviii) the cost of any utilities consumed in Building II inasmuch as the utilities for the Building are being separately metered and paid for by Tenant or the cost of any "tap fees" or one-time lump sum sewer or water connection fees for the Corporate Park payable in connection with the initial construction of the Corporate Park; (xix) any costs, fines or penalties incurred as a result of a violation by Landlord of any legal requirements which Landlord is required to comply with under the terms of this Lease; (xx) all costs and expenses (including services and utilities) paid directly by Tenant to the party (other than Landlord) from whom Tenant ordered such services; (xxi) costs for repairing, replacing or otherwise correcting defects (but not the costs of repair or normal wear and tear) in the initial construction of the Building or Building II; (xxii) Insurance Premiums or any premiums for insurance excluded from Insurance Premiums, Real Estate Taxes or any taxes excluded from Real Estate Taxes (Insurance Premiums and Real Estate Taxes being separately addressed elsewhere in this Lease);

(xxix) costs of the installation of signs identifying the occupant, owner and/or manager of Building II; and (xxx) the cost of provision of electronic cards or security keys for Building II inasmuch as Tenant is responsible for such costs in the Building. There shall not be duplication in charges to Tenant by reason of the provisions setting forth Tenant's obligation to reimburse Landlord for CAM Costs and any other provision in this Lease. It is expressly further agreed that Tenant shall not be billed for any costs incurred by reason of the construction of Building II or resurfacing, restoration or repair of any of the Common Area required by reason of such construction. In addition, in the event Landlord elects or is required by its tenant to provide a particular service or amenity in Building II which is not provided to Tenant (e.g., Landlord places a concierge in Building II or a security guard), the cost of such amenity or service shall expressly not be included in CAM Costs. 7.4. Management Fee. In addition to Tenant's Proportionate Share of CAM Costs, Tenant shall pay to Landlord, for each Calendar Year, an administrative fee for managing the Common Area equal to three percent (3%) of the Basic Rent payable by Tenant during such Calendar Year (the "Management Fee"). There shall be no other fee for management, overhead or supervision by Landlord included in CAM Costs, except as provided in Section 7.2(i). 7.5. Estimated Payment. Prior to the Commencement Date and prior to the first day of each Calendar Year thereafter during the Term, Landlord shall submit to Tenant an estimate of the CAM Costs expected to be incurred by Landlord during the upcoming Calendar Year and a statement of Tenant's Proportionate Share of such estimated annual CAM Costs. In addition to 16 the Basic Rent, Tenant shall pay to Landlord, beginning on the Commencement Date and continuing on the first day of each month thereafter during each Calendar Year, one-twelfth (1/12) of the estimated annual amount of Tenant's Proportionate Share of CAM Costs as set forth in Landlord's statement, plus one-twelfth (1/12) of the Management Fee payable for that Calendar Year. However, if the Commencement Date is a day other than the first day of a calendar month, then the installment of CAM Costs and Management Fee for the first month of the Term shall be pro rated on the basis of a thirty (30)-day month. If Landlord fails to give Tenant notice of its estimated payments due under this Section for any Calendar Year, then Tenant shall continue making monthly estimated payments in accordance with the estimate for the previous Calendar Year until a new estimate is provided. When the new estimate is provided, Tenant's monthly estimated payments shall be adjusted in accordance with the new estimate and if any deficiency exists in the payments already made for the Calendar Year in question, the deficiency shall be paid with the next monthly installment of Basic Rent. No delay by Landlord in providing any estimate under this Section or any statement under Section 7.5 shall excuse Tenant from paying Tenant's Proportionate Share of CAM Costs or the Management Fee for any period within the Term. If Landlord determines during any Calendar Year that, because of unexpected increases in CAM Costs, Landlord's estimate of the CAM Costs for that Calendar Year was too low, then Landlord shall have the right to give a new statement of the estimated Tenant's Share of CAM Costs for such Calendar Year or the balance thereof and to bill Tenant for any deficiency which may have accrued during such Calendar Year, and Tenant shall thereafter pay monthly estimated payments based on such new statement. The initial amount of Tenant's estimated monthly payments of CAM Costs and Management Fee shall be Two Thousand Seven Hundred Sixty-Five and 11/100 Dollars ($2,765.11) per month (exclusive of Real Estate Taxes, Insurance Premiums, and any costs of maintaining and repairing the Building). 7.6. Actual CAM Costs. Within ninety (90) days after the end of each Calendar Year or as soon thereafter as reasonably practicable, Landlord shall submit a statement to Tenant showing the actual CAM Costs incurred by Landlord for such Calendar Year and the amount of Tenant's Proportionate Share of such actual CAM Costs. If, for any Calendar Year, Tenant's estimated payments exceeded Tenant's Proportionate Share of actual CAM Costs, Tenant shall receive a credit in the amount of the overpayment toward Tenant's next monthly payments of CAM Costs. If, for any Calendar Year, Tenant's estimated monthly payments were less than Tenant's Proportionate Share of actual CAM Costs, then Tenant shall pay the total amount of such deficiency to Landlord within thirty (30) days after receipt of the statement from Landlord. Landlord's and Tenant's obligations with respect to any overpayment or underpayment of Tenant's Proportionate Share of CAM Costs shall survive the expiration or termination of this Lease. 7.7. Audit Rights. Tenant or its agent shall have the right, for a period of ninety (90) days after Tenant's receipt of the statement of actual CAM Costs for each Calendar Year, and upon giving reasonable notice to Landlord and during normal business hours, to audit, review and inspect at Landlord's offices Landlord's bills, invoices and records applicable to the actual CAM Costs for that particular Calendar Year to verify the CAM Costs. Such audit, review and inspection shall be at Tenant's sole cost, except as otherwise provided below. Unless otherwise mutually agreed, should such audit, review or inspection result in a dispute by Tenant as to the CAM Costs charged by Landlord, such dispute shall be determined by arbitration, in the 17 jurisdiction in which the Building is located, in accordance with the then current commercial rules of the American Arbitration Association. The costs of the arbitration shall be divided equally between Landlord and Tenant, except that each party shall bear the cost of its own legal fees, unless (i) the arbitration results in a determination that Landlord's statement contained a discrepancy of less than five percent (5%) in Landlord's favor, in which event Tenant shall bear all costs incurred in connection with such arbitration, including, without limitation, reasonable legal fees, or (ii) the arbitration results in a determination that Landlord's statement contained a discrepancy of at least five percent (5%) in Landlord's favor, in which event Landlord shall bear all costs incurred in connection with such arbitration, including, without limitation, reasonable legal fees. If such review, audit or inspection reveals that Landlord overstated Tenant's obligation for CAM Costs in any Calendar Year, the excess shall be credited against Tenant's next monthly payments of CAM Costs. If such review, audit or inspection reveals that Landlord understated Tenant's obligation for CAM Costs in any Calendar Year, Tenant shall pay the total amount of such deficiency to Landlord within thirty (30) days after such determination. During the pendency of any audit or arbitration proceedings as provided for in this Section, Tenant shall continue to make payments of CAM Costs as required by this Lease. ARTICLE VIII TAXES 8.1. Tenant's Obligation. Tenant shall be liable for Tenant's Proportionate Share of all Real Estate Taxes for any period falling within the Term. "Real Estate Taxes" shall mean all taxes and assessments, general or special, ordinary or extraordinary, foreseen or unforeseen, assessed, levied or imposed by any governmental authority upon the Corporate Park, and the rental, revenue or receipts derived therefrom, under the current or any future taxation or assessment system or modification of, supplement to, or substitute for such system. Real Estate Taxes shall not include any special assessments for public improvements, including, without limitation, road improvement assessments, special use area assessments, and school district assessments (collectively, "Special Assessments") levied as of the Date of Lease, but shall include Special Assessments levied after the Date of Lease and annual sewer and water front foot benefit charges. If at any time the method of taxation prevailing at the Date of Lease shall be altered so that in lieu of, as a substitute for or in addition to the whole or any part of the taxes now levied or assessed, there shall be levied or assessed a tax of whatever nature, then the same shall be included as Real Estate Taxes hereunder. Further, for the purpose of this Article, Real Estate Taxes shall include the reasonable expenses (including, without limitation, reasonable attorneys' fees) incurred by Landlord in challenging or obtaining or attempting to obtain a reduction of Real Estate Taxes, regardless of the outcome of such challenge, provided that such challenge relates to a period elapsing during the Term (and in the event any challenge pertains to a period extending either before or after the Term, the costs of that challenge shall be appropriately prorated based upon the period covered by such challenge in relationship to the Term). Notwithstanding the foregoing, Landlord shall have no obligation to challenge Real Estate Taxes. If, as a result of any such challenge, a tax refund is made to Landlord, then the amount of such refund, less the expenses of the challenge shall be deducted from Real Estate Taxes due in the Lease Year such refund is received. Real Estate Taxes shall not include any (i) interest and penalties due to late payment (or late filing of returns) by Landlord, unless caused by Tenant's late payment or nonpayment, (ii) franchise, capital stock, or similar taxes of Landlord, (iii) any income, excess profits, or other taxes of Landlord determined on the basis of its income, 18 receipts, or revenues, (iv) any sales or excise tax imposed on the rent payable by Tenant under the Lease, (v) any estate, inheritance, succession, gift, capital levy, or similar tax of Landlord, and (vi) any transfer taxes (except as provided in Section 27.18), recording fees, tap fees, excise taxes, license fees, permit fees, impact fees, or inspection fees payable in connection with Landlord's completion of the Corporate Park or any part thereof. Real Estate Taxes shall specifically exclude any abatements, reductions or credits received by Landlord. Assessments which may be paid over a period in excess of twelve months without penalties shall be included within taxes only to the extent such payments are required to be made within the particular Calendar Year. In the event any contest or appeal of the Real Estate Taxes for any given year shall result in a refund of taxes previously paid by Tenant, Tenant will receive its proportionate share of the amount of the net refund, inclusive of any interest received by Landlord by reason of the refund of taxes (i.e., the net amount remaining after paying all costs and expenses of securing the refund, including reasonable attorneys fees). 8.2. Estimated Payment. Prior to the Commencement Date and prior to the first day of each Calendar Year thereafter during the Term, Landlord shall submit to Tenant a reasonable estimate of the Real Estate Taxes expected to be incurred by Landlord during the upcoming Calendar Year and a statement of Tenant's Proportionate Share of such estimated annual Real Estate Taxes. In the event that any tax bill imposes Real Estate Taxes on both the Building and Building II without allocating such Taxes as between the two (2) buildings, then, for the purposes of this Section and Section 8.3, the Real Estate Taxes allocable to the Building shall be determined by reference to the tax assessor's worksheet for the Corporate Park. It is the express intent of the parties that Tenant shall not be obligated to pay any Real Estate Taxes levied, imposed, or assessed against Building II. In addition to the Basic Rent, Tenant shall pay to Landlord, beginning on the Commencement Date and continuing on the first day of each month thereafter during each Calendar Year, one-twelfth (1/12) of Tenant's Proportionate Share of annual Real Estate Taxes as set forth in Landlord's statement. However, if the Commencement Date is a day other than the first day of a calendar month, then the installment of Real Estate Taxes for the first month of the Term shall be pro rated on the basis of a thirty (30)-day month. If Landlord fails to give Tenant notice of its estimated payments due under this Section for any Calendar Year, then Tenant shall continue making monthly estimated payments in accordance with the estimate for the previous Calendar Year until a new estimate is provided. When the new estimate is provided, Tenant's monthly estimated payments shall be adjusted in accordance with the new estimate and if any deficiency exists in the payments already made for the Calendar Year in question, the deficiency shall be paid with the next monthly installment of Basic Rent. No delay by Landlord in providing any estimate under this Section or any statement under Section 6.3 shall excuse tenant from paying Tenant's Proportionate Share of Real Estate Taxes for any period within the Term. The initial amount of Tenant's estimated monthly payments of Real Estate Taxes shall be Three Thousand Three Hundred Ninety-Six and 51/100 Dollars ($3,396.51) per month. 8.3. Actual Real Estate Taxes. Within ninety (90) days after the end of each Calendar Year or as soon thereafter as reasonably practicable, Landlord shall submit a statement to Tenant showing the actual Real Estate Taxes incurred by Landlord for such Calendar Year and the amount of Tenant's Proportionate Share of such actual Real Estate Taxes. If, for any Calendar Year, Tenant's estimated payments exceeded Tenant's Proportionate Share of actual Real Estate Taxes, Tenant shall receive a credit in the amount of the overpayment toward Tenant's next 19 monthly payment of Real Estate Taxes. If, for any Calendar Year, Tenant's estimated monthly payments were, less than Tenant's Proportionate Share of actual Real Estate Taxes, then Tenant shall pay the total amount of such deficiency to Landlord within thirty (30) days after receipt of the statement from Landlord. Landlord's and Tenant's obligations with respect to Real Estate Taxes shall survive the expiration or termination of this Lease. 8.4. Separate Assessment. (i) Despite the foregoing, if the Building is separately assessed for tax purposes, or if the portion of the Land upon which the Building is located is established as a separate tax parcel by subdivision or otherwise, Tenant, in lieu of paying Tenant's Proportionate Share of Real Estate Taxes applicable to the entire Corporate Park, shall pay the separate Real Estate Taxes assessed to the Building and such tax parcel, as applicable within thirty (30) days of billing from the Landlord. Tenant, however, shall not be required to pay such Real Estate Taxes more than thirty (30) days before the last date upon which such Real Estate Taxes may be paid without penalty. If, however, Landlord's Mortgagee requires that Landlord deposit in escrow funds for the payment of Real Estate Taxes on the Building and the Land, Tenant shall pay such separate Real Estate Taxes on a monthly basis in the same manner as is set forth in Section 8.2 and an annual reconciliation shall be made in the same manner as is set forth in Section 8.3, as if Tenant were paying Tenant's Proportionate Share of Real Estate Taxes applicable to the entire Corporate Park. (ii) In the event that the portion of the Land upon which the Building is located is established as a separate tax parcel (and only in that event), Tenant, after prior written notice to Landlord and at Tenant's sole expense, may contest by appropriate legal proceedings conducted in good faith and with due diligence, the amount, validity or application, in whole or in part, of any Real Estate Taxes assessed against such separate tax parcel (including the Building). Landlord, upon request by Tenant, shall join in any such contest, but without any expense to Landlord, or if required by law or regulation in order for Tenant to conduct such contest, shall prosecute such contest, at Tenant's direction and expense. In addition, Landlord shall cooperate with Tenant and execute any documents or pleadings legally required to permit Tenant to conduct such contest, provided that none of the same shall result in any expense or liability to Landlord, if, as a result of any such challenge, a tax refund is made to Landlord, then the amount of such refund attributable to Real Estate Taxes previously paid by Tenant, less the reasonable expenses of the challenge incurred by Landlord, if any, shall be paid to Tenant within fifteen (15) days following receipt by Landlord, Landlord's obligation to return to Tenant any such Real Estate Taxes shall survive the expiration or termination of the Lease. Landlord agrees to promptly provide Tenant with a copy of any tax bill, or appeal notice so as to enable Tenant to exercise its rights hereunder. Tenant shall promptly provide Landlord with a copy of any notice received by Tenant relating to Real Estate Taxes. 8.5. Initial Payment of Real Estate Taxes. The parties recognize that the Real Estate Taxes for the Corporate Park must be paid annually in advance and that, on the Commencement Date, Landlord will have already paid those taxes for the tax year then in effect (the "Initial Tax Year"). Accordingly, on the Commencement Date, Tenant shall pay to Landlord a fractional amount of Tenant's Proportionate Share of the Real Estate Taxes for the Initial Tax Year as set forth on a tax statement provided by Landlord to Tenant on or before the Commencement Date. Such amount shall be determined by multiplying Tenant's Proportionate Share of such Real Estate Taxes for the entire Initial Tax Year by a fraction, the numerator of which shall be the 20 number of days remaining in the Initial Tax Year from and including the Commencement Date, and the denominator of which shall be 365. This amount shall be paid in addition to the payments of Tenant's Proportionate Share of Real Estate Taxes provided for in Section 8.2. 8.6. Personal Property Taxes. Tenant shall be liable for, and shall timely pay, all taxes levied against personal property and trade fixtures placed by Tenant in the Building. In no event shall any taxes on personal property or trade fixtures arising by reason of items placed or located in Building II be included in Real Estate Taxes. ARTICLE IX PARKING 9.1. Parking Spaces. During the Term, Tenant shall have the right to use the Parking Space Allocation without charge of any kind. The Parking Space Allocation shall be unreserved and non-exclusive parking spaces as set forth in Section 1.13. 9.2. Changes to Parking Facilities. Landlord shall have the right, from time to time, without Tenant's consent, subject to Tenant's right of quiet enjoyment, to change, alter, add to, temporarily close or otherwise affect the Parking Facilities in such manner as Landlord, in its sole discretion, deems appropriate, including, without limitation, the right to designate reserved spaces available only for use by one or more tenants (however, no such reserved spaces shall be located adjacent to the Building unless for Tenant's use) and in such event, those parking spaces shall still be deemed Common Area for the purpose of the definition of CAM Costs, provided that (except in emergency situations or situations beyond Landlord's control) Landlord shall provide alternative Parking Facilities sufficient to provide Tenant's Parking Space Allocation within the same approximate distance as the normal Parking Facilities are from the Building. ARTICLE X USE; LEGAL COMPLIANCE Tenant shall occupy the Building solely for the Permitted Use. The Building shall not be used for any other purpose without the prior written consent of Landlord. Tenant shall comply, at Tenant's expense, with (i) all present and Future laws, ordinances, regulations and orders of the United States of America, the State of Maryland and any other public or quasi-public federal, state or local authority ("Governmental Requirements") as such Governmental Requirements apply to the Building and Tenant's use and occupancy of the same, and (ii) any reasonable requests of any Mortgagee or any insurance company providing coverage with respect to the Building. Without limiting the generality of the preceding sentence, Tenant shall comply with all Governmental Requirements pertaining to its improvement and use of the Building, including, without limitation, the Americans with Disabilities Act of 1990, as amended, and all regulations promulgated thereunder (the "ADA"). Tenant shall not use or occupy the Building in any manner that is unlawful or dangerous or that shall constitute waste, unreasonable annoyance or a nuisance to Landlord or the other tenants of the Corporate Park. However, Tenant shall not be required to comply with any Governmental Requirements (i) which would require Tenant to perform any Alterations if Tenant's use of the Building without such Alterations is "grandfathered" under Governmental Requirements, (ii) which are required by reason of use or construction within any portion of the Corporate Park beyond the Building or (iii) which would 21 require Tenant to correct or cure any defect or deficiency in work performed by Landlord which has been noted in consent shall not be unreasonably withheld, conditioned or delayed. If Tenant desires to assign this Lease or sublet all or any part of the Building, Tenant shall notify Landlord in writing of such desire and the notice shall set forth the name and address of the proposed assignee in writing by Tenant to Landlord within six (6) months after the earlier of the Commencement Date or the date that Tenant has taken occupancy of the Building. Tenant shall not use, store or dispose of any hazardous, dangerous, inflammable, toxic or explosive materials in the Building or otherwise act in a manner which will increase Landlord's insurance rates as set forth in section 17.1 below. Landlord shall not have any liability for violations of Governmental Requirements created by Tenant. ARTICLE XI ASSIGNMENT AND SUBLETTING 11.1. Consent. Except as otherwise provided herein, Tenant shall not assign, transfer, mortgage or otherwise encumber this Lease or sublet (or permit a third party to occupy or use) all or any part of the Building, nor shall any assignment or transfer of this Lease occur by operation of law or otherwise, without the prior written consent of Landlord in each instance. Landlord's subtenant, the rent and all other sums to be paid under the proposed assignment or sublease, and all other material terms of the proposed assignment or sublease. The notice shall be accompanied by a current financial statement for the proposed assignee or subtenant prepared in accordance with GAAP and certified as correct by the chief financial officer or other authorized officer of the proposed assignee or subtenant. In addition, Landlord shall be entitled to review the documentation of the proposed assignment or sublease. Tenant shall also furnish to Landlord such additional information about the proposed assignee, or subtenant and its intended use of the Building as Landlord may reasonably request. Without limiting the matters which Landlord may take into consideration in determining whether to grant or deny its consent to the proposed assignment or sublease, Landlord shall be deemed to be reasonable in denying its consent (i) if the proposed assignee or subtenant is not reputable or does not have a previous record of honoring lease, credit and other legal obligations or does not have a tangible net worth reasonably indicating that it is capable of satisfying its financial obligations under this Lease or the proposed sublease, as the case may be, in addition to its other liabilities, or (ii) if the use intended to be made of the Building by the proposed assignee or subtenant, although in accordance with the Permitted Use, would interfere with any of the other uses being conducted in the Corporate Park or is not of a character in keeping with a first class office/R&D center. Within fifteen (15) days after written request by Landlord, Tenant shall pay to Landlord the reasonable attorneys' fees incurred by Landlord in connection with Tenant's request for consent to the assignment or subletting, up to a maximum of $1,000.00 for each such Tenant request. Any permitted assignment or sublease shall be subject to all of the terms of this Lease. In the event of a permitted assignment or sublease of twenty percent (20%) or more of the rentable area of the Building, other than a No Consent Transfer (as defined below), Tenant shall pay to Landlord, as and when received by Tenant, fifty percent (50%) of all rent, additional rent, or other consideration paid to Tenant by the assignee or subtenant in excess of the Rent payable by Tenant pursuant to this Lease, after recovery by Tenant of any remodeling, move-in or other concession, brokerage, and legal expenses incurred by Tenant with respect to the assignment or transfer. Any assignment, transfer, encumbrance, or subletting undertaken without Landlord's written consent shall be voidable by Landlord and, at Landlord's election, constitute an Event of 22 Default. Neither the consent by Landlord to any assignment, transfer or encumbrance of this Lease or subletting of all or any portion of the Building, nor the collection or acceptance by Landlord of rent from any assignee, subtenant or occupant shall be construed as a Waiver or release of any Tenant or Guarantor from the terms and conditions of this Lease or relieve Tenant or any subtenant, assignee or other party from obtaining the consent in writing of Landlord to any further assignment, transfer, encumbrance or subletting. Tenant hereby assigns to Landlord the rent and other sums due from any subtenant, assignee or other occupant of the Building and hereby authorizes and directs each such subtenant, assignee or other occupant to pay such rent or other sums directly to Landlord; provided, however, that until the occurrence of an Event of Default, Tenant shall have the license to continue collecting such rent and other sums. For purposes of this Section 11.1, except during any period in which Tenant's stock is publicly traded and except with respect to transfers made in connection with a proposed public offering or debt placement by Tenant, a "Control Transfer" (defined below) shall be deemed to be an assignment of this Lease subject to Landlord's reasonable approval as set forth above. "Control Transfer" means a transfer by Stephen J. Trevisan, at any one time or cumulatively, of fifty percent (50%) or more of the beneficial interests which he holds in Tenant as of the Date of Lease (whether stock, partnership interests, membership interests or other form of ownership or control), other than to his estate, court appointed representative in the case of incompetency, spouse, descendants, or trust for the benefit of his spouse and/or descendants. A dilution of Mr. Trevisan's beneficial interests in Tenant resulting from the issuance by Tenant of additional stock or other beneficial interests shall not be deemed to be a Control Transfer so long as Mr. Trevisan continues to hold at least a five percent (5%) ownership interest in Tenant after the transfer. Landlord shall be entitled to reject any proposed Control Transfer to a party (a) that is known in the community as being of bad moral character; (b) that is controlled, directly or indirectly, by persons who have been convicted of felonies in any state or federal court; or (c) that has failed to honor its material financial obligations within the five (5) year period immediately preceding the effective date of the proposed Control Transfer (a "Non-Permissible Party"). In the event of a proposed Control Transfer to a party other than a Non-Permissible Party, if the transfer is not approved by Landlord, the Control Transfer may nevertheless take place if, prior to the effective date of such transfer, Tenant delivers to Landlord an additional Security Deposit. The additional Security Deposit shall (1) be in the form of cash or a letter of credit meeting the requirements of Section 6.1, (2) be in an amount sufficient to increase the total amount of the Security Deposit under this Lease to Five Hundred Thousand Dollars ($500,000) if the effective date of the Control Transfer occurs prior to the commencement of the ninth (9th) Lease Year or Three Hundred Thousand Dollars ($300,000) if the effective date of the Control Transfer occurs on or after the commencement of the ninth (9th) Lease Year (or during the Renewal Period), and (3) be subject to the terms of Section 6.1 as if it were a part of the original Security Deposit. Upon the posting of the additional Security Deposit, the reduction provisions of Section 6.2 shall not apply. Instead, if the additional Security Deposit is posted prior to the commencement of the ninth (9th) Lease Year, then the total amount of the Security Deposit may be reduced to Three Hundred Thousand Dollars ($300,000) upon the commencement of the ninth (9th) Lease Year and shall remain at that amount for the duration of the Term (including the Renewal Period). 11.2. Surrender. In the event of an assignment or subletting not consented to by Landlord, Landlord shall have the right, by notice given to Tenant, to terminate this Lease in its entirety in the event of an assignment or as to the subleased portion of the Building in the event 23 of a sublease, and to require that all or part, as the case may be, of the Building be surrendered to Landlord for the balance of the Term. 11.3. Permitted Assignment and Subletting. Notwithstanding any other provision of this Lease to the contrary, Tenant has the right to assign this Lease or sublet the Building in whole or in part to any subsidiary of Tenant, affiliate of Tenant, or successor corporation or successor partnership to Tenant with financial strength equal to or greater than that of Tenant, without Landlord's consent, upon giving Landlord ten (10) days' prior written notice of such assignment or subletting. Any such assignment or subletting is herein referred to as a "No Consent Transfer". A "subsidiary" of Tenant shall mean any corporation having fifty-one percent (51%) or more, of its outstanding voting stock owned, directly or indirectly, by Tenant. An "affiliate" of Tenant shall mean any corporation which, directly or indirectly, controls or is controlled by or is under common control with Tenant. For the purpose of the definition of "affiliate", the word "control" (including "controlled by" and "under common control with"), as used with respect to any corporation, partnership, or association shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policy of a particular corporation, partnership or association, whether through the ownership of voting securities or by contract or otherwise. A "successor corporation or successor partnership" shall mean any corporation or partnership into which Tenant is merged or with which Tenant is consolidated or to which all or a substantial portion of Tenant's assets are transferred. In addition Tenant, without the necessity of Landlord's consent, shall be entitled to enter into subleases or license agreements with parties who are bona-fide joint venture partners with Tenant in particular drug testing projects, provided that Tenant or any subsidiary, affiliate, or successor corporation of Tenant shall continue to occupy not less than eighty percent (80%) of the rentable area of the Building after such sublease or license. ARTICLE XII MAINTENANCE AND REPAIR 12.1. Landlord's Obligation. From and after the Date of Lease and throughout the Term, Landlord shall keep and maintain, in good condition and repair and in a manner consistent with comparable properties in the Gaithersburg, Maryland area, the following: (i) the Land and the Common Area, and (ii) the structural elements, foundation, exterior walls, and roof of the Building, including, without limitation, masonry, curtain walls, structural walls, columns, and floor slab (collectively, the "Building Structure") but excluding exterior doors and windows. Landlord shall comply with Governmental Requirements as they relate to the Land, Common Area, and Building Structure. The cost of maintenance, repairs, and replacements to the Land and Common Area shall be included in the CAM Costs (unless otherwise expressly excluded under this Lease or the responsibility of Landlord under Article XXI) and paid by Tenant as provided in Article VII. Subject to the provisions of Article XXI and Section 17.6, the cost of maintenance and repairs to the Building Structure shall be advanced by Landlord but reimbursed to Landlord by Tenant within thirty (30) days after written request by Landlord, accompanied by evidence of these costs. The cost of replacements to the Building Structure shall be paid by Landlord without reimbursement by Tenant. Subject to the provisions of Article XXI and Section 17.6, if any repairs or replacements to the Land, Common Area, or Building Structure are necessitated by the negligence or willful misconduct of Tenant, its assignees or subtenants, or its or their agents, servants, employees, contractors, invitees, licensees, customers or subtenants 24 ("Permittees"), Tenant, at its own expense, shall promptly shall make such repairs and replacements [or, if requested by Landlord, Tenant will reimburse Landlord for the costs of such repairs and replacements within thirty (30) days of written demand]. Tenant shall promptly notify Landlord of any maintenance, repairs, and replacements to the Land, Common Area, or Building Structure of which Tenant becomes aware. 12.2. Tenant's Obligation. From and after the Date of Lease and throughout the Term, Tenant, at its sole expense, shall maintain in good condition and repair and in a manner consistent with comparable buildings in the Gaithersburg, Maryland area the entire Building, except for the Building Structure, including, without limitation, the mechanical systems (i.e., the plumbing, electrical, and HVAC systems), sprinkler system, security system, and loading docks, Tenant's obligation under this Section shall include, without limitation, the maintenance, repair, and replacement of any equipment, fixtures or other improvements to the Building that are part of the Tenant Work as defined in Exhibit B, all doors and windows of the Building, all plumbing, electrical, and HVAC facilities and equipment within the Building, and all personal property within the Building. Subject to the provisions of Section 17.6 below, Tenant also shall be responsible for (a) the full cost of repairs (including interest thereon at the Interest Rate from the date due until paid) of any and all damage caused by Tenant or its Permittees to the Building and Common Area, ordinary wear and tear and damage by fire, casualty or condemnation excepted, and (b) the maintenance, repair, and replacement of Tenants Sign in accordance with Section 14.2, the Rooftop Equipment in accordance with Section 15.3, and the Outdoor Generator in accordance with Section 1.5.4. Tenant, at its own expense, shall keep in force throughout the Term a contract for maintenance of the HVAC system serving the Building with a competent, licensed mechanical contractor and shall cause the HVAC to be regularly maintained by such mechanical contractor so that the system remains in good condition at all times. 12.3. Landlord's Right to Maintain or Repair. If, within fifteen (15) days following written notice to Tenant (or within such shorter time as may reasonably be designated by Landlord if exigent circumstances require prompter action), Tenant fails to perform any maintenance, repair, or replacement which Tenant is obligated to perform under Section 12.2 or elsewhere in this Lease, Landlord may, at its option, cause such maintenance, repairs or replacements to be made.

ARTICLE XIII INITIAL CONSTRUCTION; ALTERATIONS 13.1. Initial Construction. Landlord and Tenant agree that the construction of the Tenant Work and other initial construction with respect to the Building shall be performed in accordance with Exhibit B attached hereto and made a part hereof. 13.2. Alterations. Tenant shall not make or permit any Alterations, without the prior written consent of Landlord. Such consent shall not be unreasonably withheld or delayed in the case of interior Alterations which do not affect the structure, roof, foundation, exterior walls, or mechanical or sprinkler systems of the Building and may be granted or withheld in Landlord's sole discretion in the case of all other Alterations. Landlord may impose any reasonable 25 conditions to its consent to Alterations, including, without limitation, (i) delivery to Landlord, as the work progresses, of partial waivers of mechanic's and materialmen's liens with respect to the Building and the Land for all work, labor and services performed and materials furnished, signed by all contractors, subcontractors, materialmen and laborers participating in the Alterations (with a final fully executed release of liens to be delivered to Landlord upon completion of the Alterations), (ii) prior approval of the plans and specifications and Tenant's contractor(s) with respect to the Alterations, and (iii) supervision by Landlord or Landlord's representative of the Alterations.

If the Alterations are not performed in accordance with the terms hereof, Landlord shall have the right, at Landlord's option, to halt any further Alterations, or to require Tenant to construct the Alterations as herein required or, in the event that Tenant begins performing the Alterations without first obtaining Landlord's prior written consent, to require Tenant to restore the Building to the condition, in which they existed before such Alterations. Notwithstanding the foregoing, if any mechanic's or materialmen's lien is filed against the Building or the Land for work claimed to have been done for, or materials claimed to have been furnished to or for the benefit of Tenant, such lien shall be discharged of record by Tenant within fifteen (15) days after the date of filing by the payment thereof or the filing of any bond required by law. If Tenant shall fail to timely discharge any such lien, Landlord may (but shall not be obligated to) discharge the same, the cost of which shall be paid by Tenant within ten (10) days of demand by Landlord. Such discharge, by Landlord shall not be deemed to waive or release the default of Tenant in not discharging the same. Neither Landlord's consent to the Alterations nor anything contained in this Lease shall be deemed to be the agreement or consent of Landlord to subject Landlord's interest in the Building or the Land to any mechanic's or materialmen's liens which may be filed in connection with the Alterations. Tenant shall be entitled to install normal decorations in the Building without Landlord's prior consent. 13.3. Removal of Alterations.

Notwithstanding the foregoing, Landlord shall not be entitled to require the removal of any Alteration unless Landlord advises Tenant in writing, not later than six (6) months before the expiration of the Term, that removal of that Alteration is required. If Landlord requires the removal of all or part of the Alterations, Tenant, at its expense, shall repair any damage to the Building caused by such removal. If Tenant fails to remove any Alterations which Landlord has requested be removed, then Landlord may (but shall not be obligated to) remove the same and the cost of such removal and repair of any damage caused by the same, together with any and all damages which Landlord may suffer and sustain by reason of the failure of Tenant to remove the same, shall be charged to and paid by Tenant upon demand. 26 13.4. Landlord Alterations. Landlord shall have no obligation to make any Alterations in or to the Building, the Common Area or the Land except as specifically provided in the Work 17 Agreement or otherwise herein. Landlord hereby reserves the right, from time to time, to erect such scaffolding and other aids to construction adjacent to and about the Building as Landlord reasonably deems appropriate, and, subject to Tenant's right of quiet enjoyment, no such construction or erection shall constitute an eviction, constructive or otherwise, or permit Tenant any abatement of Rent or other claim.

In addition, Tenant's commercial general liability policy shall name Landlord and Landlord's Mortgagee, or any successor or assign thereof that Landlord shall designate in writing, as additional insured parties. On or before the Commencement Date and, thereafter not less than thirty (30) days before the expiration date of any insurance policy required to be maintained under this Article XVII, an original of such policy (including any renewal or replacement policy) or a certified copy or certificate of insurance thereof, together with evidence satisfactory to Landlord of the payment of all premiums for such policy, shall be delivered to Landlord and, at Landlord's request, to any Mortgagee. 17.5.

Notwithstanding the foregoing, Landlord's property insurance shall not be required to cover the Items required to be covered by Tenant's property insurance under Section 17.3. Tenant shall pay for the cost of the insurance which Landlord is required to maintain under this Section, as well as any other insurance which Landlord elects to maintain with respect to the Building and/or Corporate Park (collectively, "Insurance Premiums"), as follows: (a) Prior to the Commencement Date and prior to the first day of each Calendar Year thereafter during the Term, Landlord shall submit to Tenant an estimate of the Insurance Premiums expected to be incurred by Landlord during the upcoming Calendar Year and a statement of Tenant's Proportionate Share of such estimated annual Insurance Premiums. In addition to the Basic Rent, Tenant shall pay to Landlord, beginning on the Commencement Date and continuing on the first day of each month thereafter during each Calendar Year, one-twelfth (1/12) of Tenant's Proportionate Share of annual Insurance Premiums as set forth in Landlord's statement. However, if the Commencement Date is a day other than the first day of a calendar month, then the installment of Insurance Premiums for the first month of the Term shall be pro rated on the basis of a thirty (30) day month. If Landlord fails to give Tenant notice of its estimated payments due under this Section for any Calendar Year, then Tenant shall continue making monthly estimated payments in accordance with the estimate for the previous Calendar Year until a new estimate is provided, When the new estimate is provided. Tenant's monthly estimated payments shall be adjusted in accordance with the new estimate and if any deficiency exists in the payments already made for the Calendar Year in question, the deficiency shall be paid with the next monthly installment of Basic Rent. No delay by Landlord in providing any estimate under this Section or any statement under Section 7.5(b) shall excuse Tenant from paying Tenant's Proportionate Share of Insurance Premiums for any period within the Term. The initial amount of Tenant's estimated monthly payments of Insurance Premiums shall be Three Hundred Seventy and 13/100 Dollars ($370.13) per month. (b) Within ninety (90) days after the end of each Calendar Year or as soon thereafter as reasonably practicable, Landlord shall submit a statement to Tenant showing the actual Insurance Premiums incurred by Landlord for such Calendar Year and the amount of Tenant's Proportionate Share of such actual Insurance Premiums. If, for any Calendar Year, Tenant's estimated payments exceeded Tenant's Proportionate Share of actual Insurance Premiums, Tenant shall receive a credit in the amount of the overpayment toward Tenant's next monthly payment of Insurance Premiums. If, for any Calendar Year, Tenant's estimated monthly payments were less than Tenant's Proportionate Share of actual Insurance Premiums, then Tenant shall pay the total amount of such deficiency to Landlord within thirty (30) days after receipt of the statement from Landlord. Landlord's and Tenant's obligations with respect to any overpayment or underpayment of Tenant's Proportionate Share of Insurance Premiums shall survive the expiration or termination of this Lease. 31 (c) If Landlord carries any separate policy of insurance covering just the Building (and not the entire Corporate Park), Tenant shall pay all of the Insurance Premiums for such policy (and not just Tenant's Proportionate Share) in the same manner as is provided above. (d) Despite the foregoing, Landlord may, upon thirty (30) days prior written notice to Tenant, require Tenant to pay Insurance Premiums at such time, as they are due and payable to the insurance company or in such a manner as is required of Landlord by any Mortgagee, whether such payments be in lump-sum or other installments. 17.6. Waiver of Subrogation. Each party hereby releases the other party from any and all liability for loss or damage to property owned by the releasing party caused by the act or omission of the other party, its agents, officers or employees, to the extent such loss or damage is covered by the property insurance required to be maintained by the releasing party under this Article XVII, whether or not such insurance is, in fact, so maintained; provided that such release (i) shall not apply to the extent of any deductible provided for by the releasing party's policy of property insurance, up to a maximum amount of Twenty-Five Thousand Dollars ($25,000), and (ii) shall be effective only as to a loss or damage occurring while the appropriate policy of insurance of the releasing party provides that such release shall not impair the effectiveness of such policy or the insured's ability to recover thereunder. Each party shall use reasonable efforts to have a clause to such effect included in the insurance policies required to be maintained hereunder and shall promptly notify the other in writing if such clause cannot be included in any such policy. ARTICLE XVIII SERVICES AND UTILITIES 18.1. Intentionally Omitted 18.2. Interruption of Services. Landlord shall not be liable for, nor shall there by any abatement of Rent or constructive eviction for, the failure to furnish or the delay or suspension in furnishing any of the services, either ordinary or extraordinary, required under this Article, whether caused by breakdown, maintenance, repair, strikes, scarcity of labor or materials, acts of God or any other cause whatsoever, unless caused by the gross negligence or willful misconduct of Landlord or its Agents. In the event of any interruption of services or utilities solely resulting from any negligence or intentional misconduct by Landlord which renders Tenant unable to make reasonable use of the Building for a period of more than four (4) consecutive business days or more than an aggregate of five (5) business days in any Calendar Year, all Rent for the Building shall abate until the use is restored to Tenant of the Building. 18.3. Separate Billing. Separate meters have been installed, or will be installed as part of the Tenant Work, to measure water, sewer and other utility consumption in the Building.

No installation by Landlord of any security or alarm system for the Building and no engagement by Landlord of a professional security service for the Building (in the event that Landlord determines, in its sole discretion, to engage such a service) shall in any way increase Landlord's liability for occurrences and/or consequences which such a system or service are designed to detect or avert and Tenant shall look solely to its insurer for claims for damages or injury to any property. Tenant shall have the right to install its own security system for all or any portion of the Building at its sole cost. All employees will be issued an electronic card or conventional key for the door entry system utilized in the Building at Tenant's expense which will allow access to the Building after hours. Tenant and its Agents shall have access to the Building twenty-four (24) hours per day, seven (7) days per week. ARTICLE XIX LIABILITY OF LANDLORD 19.1. No Liability.

Any goods, automobiles, property or personal effects stored or placed by Tenant or its Agents in or about the Building or the Common Area shall be at the sole risk of Tenant, and Landlord and its Agents shall not in any manner be held responsible therefor. Except to the extent expressly prohibited by law, Landlord and Tenant each waive any claim it might have against the other or its respective Agents for any consequential damages sustained by such waiving party arising out of the loss or damage to any person or property. With respect to any provision of this Lease which provides, in effect, that Landlord shall not unreasonably withhold, condition or delay any consent or approval, Tenant shall in no event be entitled to make any claim for money damages in excess of One Hundred Thousand Dollars ($100,000) (the "Damage Limit") based upon any claim or assertion by Tenant that Landlord has unreasonably withheld, conditioned or delayed any such consent or approval in any particular instance, except the Damage Limit shall not apply to the failure of Landlord to comply with the decision rendered by the arbitrator pursuant to Section 19.4 below as soon as practicable following Landlord's receipt (or refusal of receipt) of written notice of the decision. Nothing in this Section shall be deemed to limit Tenant's right to pursue an action or proceeding to enforce any such provision by specific performance, injunction or declaratory judgment. 19.2. Tenant's Indemnity. Subject to Section 17.6, Tenant shall indemnify and hold harmless Landlord and its Agents from and against any and all damage, claim, liability, cost or expense (including, without limitation, reasonable attorney's or other professionals' fees) of 33 every kind and nature (including, without limitation, those arising from any injury or damage to any person, property or business, and those, arising from Tenant's failure to comply with all applicable provisions of the ADA) incurred by or claimed against Landlord or its Agents as a result or arising out of Tenant's or its Agents' use and occupancy of the Building or the Common Area or from Tenant's breach of this Lease, except if caused by the negligence or intentional misconduct of Landlord or its Agents or property manager.

Notwithstanding the foregoing or any other provision of this Lease, in no event shall Landlord have any liability for any in, direct, consequential, exemplary or punitive damages under this Lease. 19.4. Mandatory Binding Arbitration. The parties desire to provide a mechanism to promptly resolve disputes arising by reason of Tenant's contention that Landlord has unreasonably withhold, delayed or conditioned its consent or approval in any instance where this Lease expressly requires that such consent of approval not be unreasonably withheld, delayed or conditioned. Consequently, if, at any time and for any reason, Tenant believes that Landlord has unreasonably withheld, delayed or conditioned its consent or approval under this Lease, in contravention of the express terms of this Lease, Tenant may send written notice to Landlord requiring that such dispute be submitted to binding arbitration by a single arbitrator in accordance with the rules of the American Arbitration Association. To be effective, such notice by Tenant shall be given within thirty (30) days following Tenant's receipt (or refusal of receipt) of Landlord's written notice denying consent to or disapproving the matter at issue or setting forth Landlord's conditions to the consent or approval of such matter. The arbitrator shall be an experienced real estate attorney in the Washington, D.C. metropolitan area, who is in active practice. Absent mutual consent of Landlord and Tenant, neither such attorney nor his firm shall do any work for either Landlord or Tenant, or any individual owning more than ten percent (10%) of the ownership interests in Landlord or Tenant. In the event that Landlord and Tenant are unable mutually to agree upon the arbitrator within five (5) business days following written request from Tenant to appoint the arbitrator, then the American Arbitration Association (or any successor organization, or if none, such organization or party generally recognized in the Washington, D.C. metropolitan area as having succeeded to the American Arbitration Association) shall be required to appoint as soon as possible an arbitrator who shall qualify in accordance with the requirements set forth in the two immediately preceding sentences. Any arbitrator serving hereunder shall consider the proposed action by Tenant and the basis upon which Landlord has withheld or conditioned its consent or approval and Landlord and Tenant shall submit to each other and to the arbitrator, within five (5) business days following notice to 34 Landlord and Tenant of the arbitrator's designation, a written statement of their respective positions. At a mutually agreeable time, not less than three (3) or more than ten (10) business days after the statements are required to be submitted, the arbitrator shall hold a hearing not to exceed five (5) hours in duration unless the parties otherwise mutually agree. At the hearing each party shall present its arguments. The arbitrator shall determine the matter and issue a written decision setting forth the reasons for his or her determination no later than ten (10) business days following the hearing. The decision of the arbitrator shall be binding upon Landlord and Tenant shall be non-appealable, and may be enforced by the parties in a court of law or equity. Should the arbitrator agree that Landlord has acted reasonably, Tenant shall pay all costs of the arbitrator and, if necessary, all costs (including reasonable attorneys fees and court costs) to enforce the arbitrator's decision. Should the arbitrator agree that Landlord has failed to act reasonably, Landlord shall pay all costs of the arbitrator and, if necessary, all costs (including reasonable attorneys fees and court costs) to enforce the arbitrator's decision. Each party shall bear its own legal fees in connection with the arbitration. ARTICLE XX RULES AND REGULATIONS Tenant and its Agents shall at all times abide by and observe the Rules and Regulations and any reasonable amendments thereto that may be promulgated from time to time by Landlord for the operation and maintenance of the Corporate Park and the Common Area, and the Rules and Regulations shall be deemed to be covenants of the Lease to be performed and/or observed by Tenant. Except to the extent set forth herein, nothing contained in this Lease shall be construed to impose upon Landlord any duty of obligation to enforce the Rules and Regulations or the terms or provisions contained in any other Lease against any other tenant or occupant of the Corporate Park. Landlord shall not be liable to Tenant for any violation by any party of the Rules and Regulations or the terms of any other building lease. If there is any inconsistency between this Lease and the Rules and Regulations, this Lease shall govern. Landlord reserves the right reasonably to amend and modify the Rules and Regulations as it deems necessary upon prior written notice to Tenant. All Rules and Regulations that may be enforced by Landlord against Tenant shall be uniformly enforced among all of the tenants at the Corporate Park. Landlord shall use its reasonable efforts to enforce all of the Rules and Regulations against other tenants whose breach of such Rules and Regulations adversely affect the use of the Building or the Common Areas by Tenant or its Permittees. ARTICLE XXI DAMAGE; CONDEMNATION 21.1. Damage to the Premises. If the Building shall be damaged by fire or other cause, Landlord shall diligently, and as soon as practicable after such damage occurs, repair such damage at the expense of Landlord, except as otherwise provided in this Section 21.1 and provided, however, that Landlord shall only be obligated to repair such damage to the extent of proceeds of insurance actually received by Landlord (reduced by any proceeds retained pursuant to the rights of any Mortgagee). Notwithstanding the foregoing, (i) if the Building is damaged by fire or other cause to such an extent that, in Landlord's reasonable judgment, (a) the damage cannot be substantially repaired within two hundred seventy (270) days after the date of such damage, or (b) insurance proceeds and other funds available to Landlord are not sufficient to 35 reasonably repair such damage, or (ii) if the Building is damaged during the last two (2) Lease Years of the Term, then Landlord may terminate this Lease by giving written notice to Tenant within ninety (90) days from the date of such damage and the termination shall be effective as of the date of the notice. Further, if the Building is damaged by fire or other cause during the last Lease Year of the Term and more than thirty percent (30%) of the rentable area of the Building is rendered untenantable by such damage, Tenant may terminate this Lease by giving written notice to Landlord within ninety (90) days from the date of such damage and the termination shall be effective as of the date of the notice. If this Lease shall be terminated under this Section 21.1, the Rent shall be apportioned and paid to the date of such termination. If this Lease shall not be terminated and the damage required to be repaired by Landlord is not repaired to such an extent that the Building is tenantable for the conduct of the Permitted Use within two hundred seventy (270) days from the date of such damage, Tenant, within thirty (30) days from the expiration of such two hundred seventy day (270) period, may terminate this Lease by notice to Landlord. During the period that Tenant is deprived of the use of the damaged portion of the Building, Rent for such portion shall abate proportionately, provided that if by reason of the fire or other casualty Tenant is unable reasonably to conduct its business within the undamaged portion of the Building, all Rent shall abate as if the entire Building were untenantable. Any abatement of Rent under this Section shall continue until the first to occur of (1) expiration of fifteen (15) days following completion by Landlord of the repair or restoration of the Building or the date Landlord would have completed the repair or restoration in the absence of any delay caused by Tenant, or (2) the date Tenant resumes conduct of its business operations within all or any substantial portion of the Building (provided that the abatement shall terminate proportionately as Tenant re-occupies any portion of the Building that Tenant was forced to vacate by reason of the casualty). Notwithstanding anything in this Section 21.1 to the contrary, Landlord shall not be required to rebuild, replace or repair any damage to the Tenant Work, any Alterations made by Tenant, or any other items required to be covered by Tenant's property insurance under Section 17.3. Instead, unless this Lease terminates in accordance with this Section 21.1, Tenant shall diligently, and as soon as practicable after such damage occurs, repair such damage at the expense of Tenant and the proceeds of Tenant's property insurance shall be made available for this purpose. 21.2. Condemnation. If the whole or a Substantial Part of the Building shall be taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including, without limitation, sale under threat of such a taking) or if any portion of the Common Areas shall be taken resulting in the inability of Tenant to reasonably access the Building and the Parking Facilities, or if the Parking Facilities shall be taken and not promptly replaced with reasonably comparable and adequate parking facilities, then the Term shall cease and terminate as of the date when title vests in such governmental or quasi-governmental authority, and Rent shall be prorated to the date when title vests in such governmental or quasi-governmental authority. If less than a Substantial Part of the Building is taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including, without limitation, sale under threat of such a taking), Basic Rent and Tenant's Proportionate Share shall be reduced by the ratio that the portion so taken bears to the rentable square footage of the Building before such taking, effective as of the date when title vests in such governmental or quasi-governmental authority, and this Lease shall otherwise continue in full force and effect. Tenant shall have no claim against Landlord (or otherwise) as a result of such taking, and Tenant hereby agrees to make no claim against the condemning authority for any 36 portion of the amount that may be awarded as compensation or damages as a result of such taking; provided, however, that Tenant may, to the extent allowed by law, claim an award for moving expenses and for the taking of any of Tenant's property [other than its leasehold interest in the Building, but including the value, of the unamortized portion of any Tenant Work (loss the unamortized portion of the Tenant Improvement Allowance) and the unamortized portion of Alterations or fixtures installed by Tenant in the Building] which does not, under the term of this Lease, become the property of Landlord at the termination hereof, as long as such claim is separate and distinct from any claim of Landlord and does not diminish Landlord's award. ARTICLE XXII DEFAULT OF TENANT 22.1. Events of Default. Each of the following shall constitute an Event of Default: (i) Tenant fails to pay Rent within five (5) business days after written notice from Landlord, provided that no such notice shall be required if at least two (2) such notices shall have been given during the same Lease Year; (ii) Tenant fails to observe or perform any other term, condition or covenant herein binding upon or obligating Tenant within thirty (30) days after written notice from Landlord (or such longer period of time as may be reasonably necessary to cure the default, provided that: (a) Tenant has commenced good faith and diligent efforts to cure the default within the initial thirty (30) day period, (b) Tenant continuously pursues those efforts thereafter, to the end that the default may be cured at the earliest practicable time, and (c) in all events, the default shall be cured within sixty (60) days after Landlord's original notice); (iii) Tenant abandons or vacates the Building for a period in excess of one hundred twenty (120) days; (iv) Tenant makes or consents to a general assignment for the benefit of creditors or a common law composition of creditors, or a receiver is appointed for the Building or all or substantially all of Tenant's asset; or (v) Tenant files a voluntary petition any bankruptcy or insolvency proceeding, or an involuntary petition in any bankruptcy or insolvency proceeding is filed against Tenant and is not discharged by Tenant within sixty (60) days of such filing. 22.2. Landlord's Remedies. Upon the occurrence of an Event of Default, Landlord may, at its option, without further notice or demand to Tenant, in addition to all other rights and remedies provided in this Lease, at law or in equity: (i) Terminate this Lease and Tenant's right of possession of the Building and recover all damages to which Landlord is entitled under law, specifically including, without limitation, all of Landlord's expenses of reletting the Building (including, without limitation, rental concessions to new tenants, repairs, Alterations, reasonable legal fees, and, to the extent applicable to the portion of the relet term which coincides with the Term of this Lease which would have remained had this Lease not been terminated, brokerage commissions). If Landlord elects to terminate this Lease, every obligation of the parties shall cease as of the date of such termination, except that Tenant shall remain liable for payment of Rent and performance of all other terms and conditions of this Lease to the date of termination; (ii) Terminate Tenant's right of possession of the Building without terminating this Lease, in which event Landlord may, but shall not be obligated to, relet the Building, or any part thereof, for the account of Tenant, for such rent and term and upon such other conditions as are acceptable to Landlord, in its sole and absolute discretion. For purposes 37 of such reletting, Landlord is authorized to redecorate, repair, alter and improve the Building to the extent Landlord, in its sole, discretion, deems necessary. Until Landlord relets the Building, Tenant shall remain obligated to pay Rent to Landlord as provided in this Lease. If and when the Building is relet and if a sufficient sum is not realized from such reletting after payment of all Landlord's expenses of reletting (including, without limitation, rental concessions to new tenants, repairs, Alterations, reasonable legal fees and as limited above, brokerage commissions) to satisfy the payment of Rent due under this Lease for any month, Tenant shall pay Landlord any such deficiency upon demand. Tenant agrees that Landlord may file suit to recover any sums due Landlord under this Section from time to time and that such suit or recovery of any amount due Landlord shall not be any defense to any subsequent action brought for any amount not previously reduced to judgment in favor of Landlord. Notwithstanding the foregoing, Landlord agrees to use commercially reasonable efforts to relet the Building following a termination of Tenant's fight of possession. Landlord shall be deemed to have satisfied this obligation if it lists the Building for reletting with a reputable commercial leasing broker. (iii) Terminate this Lease and Tenant's right of possession of the Building, and recover from Tenant the net present value of the difference, if any between (a) the Rent due from the date of termination until the Expiration Date less (b) the then fair rental value of the Building, such difference, if any, to be discounted at six percent (6%) per annum; (iv) Re-enter and repossess the Building and remove all persons and effect, therefrom, by summary proceeding, ejectment or other legal action. Landlord shall have no liability by reason of any such re-entry, repossession or removal. 22.3. Rights Upon Possession. If Landlord takes possession of the Building pursuant to this Article, with or without terminating this Lease, Landlord may, at its option, enter into the Building, remove Tenant's Alterations, signs, personal property, equipment and other evidences of tenancy, and store them at Tenant's risk and expense or dispose of them as Landlord may see fit, and take and hold possession of the Building; provided, however, that if Landlord elects to take possession only without terminating this Lease, such entry and possession shall not terminate this Lease or release Tenant or any Guarantor, in whole or in part, from the obligation to pay the Rent reserved hereunder for the full Term or from any other obligation under this Lease or any guaranty thereof. 22.4. No Waiver. If Landlord shall institute proceedings against Tenant and a compromise or settlement thereof shall be made, the same shall not constitute a waiver of any other covenant, condition or agreement herein contained, nor of any of Landlord's rights hereunder. No waiver by Landlord or Tenant of any breach shall operate as a waiver of such covenant, condition or agreement, or of any subsequent breach thereof. No payment of Rent by Tenant or acceptance of Rent by Landlord shall operate as a waiver of any breach or default by Tenant under this Lease. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly installment of Rent herein stipulated shall be deemed to be other than a payment on account of the earliest unpaid Rent, nor shall any endorsement or statement on any check or communication accompanying a check for the payment of Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such Rent or to pursue any other remedy provided in this Lease. No payment by Tenant shall be deemed to constitute an accord or satisfaction, or preclude 38 Tenant recovering from Landlord amounts paid in error. No re-entry by Landlord, and no acceptance by Landlord of keys from Tenant, shall be considered an acceptance of a surrender of this Lease or the Building hereunder demised. 22.5. Right of Landlord to Cure Tenant's Default. If an Event of Default shall occur, then Landlord may (but shall not be obligated to) make such payment or do such act to cure the Event of Default, and charge the amount of the expense thereof, together with interest thereon at the Interest Rate, to Tenant. Such payment shall be due and payable upon demand; however, the making of such payment or the taking of such action by Landlord shall not be deemed to cure the Event of Default or to stop Landlord from the pursuit of any remedy to which Landlord would otherwise be entitled. Any such payment made by Landlord on Tenant's behalf shall bear interest until paid at the Interest Rate. 22.6. Late Payment. If Tenant fails to pay any Rent within five (5) days after such Rent becomes due and payable, Tenant shall pay to Landlord a late charge of five percent (5%) of the amount of such overdue Rent. In addition, any such late Rent payment shall bear interest from the date such Rent became due and payable to the date of payment thereof by Tenant at the Interest Rate. Such late charge and interest shall be due and payable within five (5) days after written demand therefor from Landlord. Despite the foregoing, no such late charge or interest shall be payable by Tenant on any late payment of Rent in the event Tenant remits to Landlord the late payment within five (5) days following written notice to Tenant that Landlord has failed to timely receive any payment to which Landlord is entitled under this Lease. However, in the event Tenant is late more than once in any period of twelve (12) consecutive months, the preceding sentence shall not apply and Landlord shall be entitled to the late charge and interest us provided above, in the case of each late payment following the first such late payment within the twelve (12) month period, without the necessity of written notice. ARTICLE XXIII MORTGAGES 23.1. Subordination. This Lease shall be subject and subordinate to all ground or underlying leases and to any Mortgage(s) which may now or hereafter affect the Land and to all renewals, modifications, consolidations, replacements and extensions thereof, provided that the Mortgagee agrees in writing, in a commercially reasonable form, that, in the event of foreclosure or deed in lieu of foreclosure under the Mortgage, it shall not terminate this Lease during the Term so long as no Event of Default exists under this Lease (such agreement being referred to as an "SNDA"). Without limiting the generality of the preceding sentence, Tenant agrees that an SNDA substantially in the form attached to and made a part of this Lease as Exhibit F is commercially reasonable and will be satisfactory to Tenant. Within thirty (30) days after the: Date of Lease, Landlord, shall obtain an SNDA in conformance with this Section from the existing Mortgagee with respect to the Land. If Landlord fails to do so, Tenant's sole recourse shall be to terminate this Lease, in which event Landlord shall promptly return to Tenant any prepaid Rent and the Security Deposit previously received by Landlord and Landlord shall reimburse Tenant for its actual out of pocket expenses for the negotiation of this Lease and the preparation of Tenant Plans under the Work Agreement, not to exceed Twenty-Five Thousand Dollars ($25,000) in the aggregate and thereafter the parties shall be relieved of all further liability under this Lease. In the event of foreclosure of a Mortgage, Tenant shall attorn to and 39 recognize the purchaser at foreclosure as Landlord under this Lease and such agreement shall be set forth in the SNDA. Tenant shall promptly execute and deliver the SNDA upon request by Landlord. Despite anything contained in this Section, before any foreclosure sale under a Mortgage, the Mortgagee shall have the absolute right to subordinate the Mortgage to this Lease. 23.2. Mortgage Protection. Tenant agrees to give any Mortgagee by certified mail, return receipt requested, a copy of any notice of default served upon Landlord, provided that Tenant has been given prior written notice of the address of such Mortgagee. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then Mortgagee shall have an additional thirty (30) days within which to cure such default; provided, however, that if such default cannot be reasonably cured within thirty (30) days, then such Mortgagee shall have such additional time as may be necessary to cure such default so long as Mortgagee has commenced and is diligently pursuing the remedies necessary to cure such default (including, without limitation, the commencement of foreclosure proceedings, if necessary), in which event this Lease shall not be terminated or Rent abated while such remedies are being so diligently pursued. In the event of the sale of the Land or the Building by foreclosure or deed in lieu thereof, the Mortgagor, or purchaser at such sale shall be responsible for the return of the Security Deposit only to the extent that such Mortgagee or purchaser actually received the Security Deposit. ARTICLE XXIV SURRENDER, HOLDING OVER 24.1. Surrender of the Building. Tenant shall peaceably surrender the Building to Landlord on the Expiration Date or earlier termination of this Lease, in broom-clean condition and in as good condition as when Tenant took possession, including, without limitation, the repair of any damage to the Building caused by the removal of any of Tenant's personal property, Alterations or trade fixtures from the Building, except for reasonable wear and tear and loss by fire, condemnation or other casualty. Any of Tenant's personal property left on or in the Building or the Common Area after the Expiration Date or earlier termination of this Lease shall be deemed to be abandoned, and, at Landlord's option, title thereto shall pass to Landlord under this Lease. Tenant shall remove said property within five (5) days of notification or Landlord shall remove or store the property at Tenant's expense. 24.2. Holding Over. In the event that Tenant shall not immediately surrender the Building to Landlord on the Expiration Date or earlier termination of this Lease, Tenant shall be deemed to be a month to month tenant upon all of the terms and provisions of this Lease except that the monthly Basic Rent shall be 150% of the monthly Basic Rent in effect during the last month of the Term. Notwithstanding the foregoing, if Tenant shall hold over after the Expiration Date or earlier termination of this Lease, and Landlord shall desire to regain possession of the Building, then Landlord may forthwith re-enter and take possession of the Building, by any legal process in force in the State of Maryland. Tenant shall indemnify Landlord against all liabilities and damages sustained by Landlord by reason of Tenant's holding over in the Building. Such indemnity shall survive the termination of this Lease. 40 ARTICLE XXV QUIET ENJOYMENT Landlord covenants that if Tenant shall pay Rent and perform all of the terms and conditions of this Lease to be performed by Tenant, Tenant shall, during the Term, peaceably and quietly occupy and enjoy possession of the Building without molestation or hindrance by Landlord or any party claiming through or under Landlord, subject to the provisions of this Lease, any Mortgage to which this Lease is subordinate (provided that an SNDA is provided), and the Permitted Title Exceptions. Tenant acknowledges and agrees that this Lease is or will be subject and subordinate to a declaration of easements, conditions, and restrictions applicable to the Crown Pointe Corporate Park and to a separate subdivision plat of record for the Land.

The Tenant Plans shall be subject to the reasonable approval of Landlord as set forth in Section 2.3. 2.3 Approvals by Landlord. (a) Promptly after preparation by the Building's Architect Tenant shall submit the Tenant Plans to Landlord, for Landlord's approval.

Landlord will not unreasonably withhold, condition, or delay its approval of Tenant Plans to the extent that the Tenant Plans provide for Tenant Work substantially similar to that depicted in the preliminary plans for such work submitted by Tenant and approved by Landlord prior to the Date of Lease or which is consistent with the improvements made by Tenant and existing as of the Date of Lease at Tenant's Firstfield Road location in Gaithersburg, Maryland. (b) Landlord shall approve or disapprove the Tenant Plans, or any modifications of these materials, within seven (7) business days following Landlord's receipt of the materials in question.

If Tenant did not give Landlord a Time Alert Notice at the time of submitting the materials to Landlord, the seven (7) business day period shall not begin to run until the Time Alert Notice is 50 given to Landlord. Moreover, the seven (7) business day period rendering Landlord's approval or disapproval of the Space Plan shall in no event commence until the complete Space Plan has been delivered to Landlord and the seven (7) business day period for rendering Landlord's approval or disapproval of the Construction Drawings shall in no event commence until a complete set of the Construction Drawings has been delivered to Landlord and, in each instance, notice to that effect has been given by Tenant to Landlord. Despite the foregoing, Tenant, at its election, may submit the Construction Drawings to Landlord in two (2) phases - the first phase consisting of the Construction Drawings for the Office Improvements and the second phase consisting of the Construction Drawings for the Remaining Improvements. In that case, upon each such submission by Tenant and notice by Tenant that it has delivered a complete act of Construction Drawings for the phase in question, the seven (7) business day period for rendering Landlord's approval of these Construction Drawings shall run from such submission and notice, provided that a Time Alert Notice has also been given. In the event that Landlord disapproves any Tenant Plans, or any revisions of Tenant Plans, within seven (7) business days after receipt, Tenant shall modify the disapproved materials to satisfy Landlord's reasonable objections and shall resubmit such materials to Landlord for Landlord's approval within seven (7) business days after receipt of Landlord's objections.

The construction of the Tenant Work shall be competitively bid by Tenant to the following four (4) contractors (the "Permitted Contractors"): Nardi Construction; Corporate Interiors; Kane Construction and Karvounis.

Landlord's approval under this Section 3.1 shall not be unreasonably withheld or delayed. 3.2 Performance of Work (a) The General Contractor selected to construct the Tenant Work shall be responsible to obtain all required permits for the work. 51 (b) After Landlord's approval of the Construction Drawings, Tenant's selection (and Landlord's approval) of the General Contractor, and Tenant's receipt of all required permits for the Tenant Work, Tenant shall promptly commence the construction of the Tenant Work and diligently pursue the same, to Substantial Completion. The Tenant Work shall be constructed under the supervision and management of Landlord or a representative of Landlord as Landlord may designate in writing to Tenant ("Landlord's Representative"). It is expressly recognized that it is the intent of Tenant to commence occupancy of the Office Improvements on or before March 1, 2001. Landlord shall use commercially reasonable efforts to assist Tenant to accomplish its move-in by that date, provided that Landlord shall not be required to incur any out of pocket expense in rendering such assistance. (c) Tenant shall cause the Tenant Work to be constructed and installed (i) in substantial accordance with the approved Construction Drawings and this Agreement, including, without limitation, Landlord's Construction Rules and Regulations attached to and made a part of this Agreement as Schedule 2, (ii) in a good and workmanlike manner, using new materials of good quality, and (iii) in accordance with all applicable Governmental Requirements, including, without limitation, the Americans with Disabilities Act.

All such variances shall be promptly corrected by Tenant. Any supervision, management, or inspection of the Tenant Work by Landlord or Landlord's Representative are for the sole benefit of Landlord. Landlord's supervision, management, and inspection of the Tenant Work shall in no event be deemed to constitute any representation or warranty by Landlord as to the quality, adequacy, or utility of the Tenant Work, the fitness of the Tenant Work for any particular purpose, or the compliance of the Tenant Work with the Construction Drawings, this Agreement, or applicable Governmental Requirements. 3.3 Payment. Subject to Section 4 below, Tenant shall promptly pay all costs of designing, obtaining permits for, and constructing the Tenant Work (collectively, the "Construction Costs"), as and when the Construction Costs are due, directly to the parties to whom such payment is due. Tenant shall hold Landlord harmless from all Construction Costs. The provisions of Section 13.2 of the Lease shall apply to any mechanic's or materialmen's liens sought to be imposed against the Building, Land or Corporate Park as a result of the Construction Costs. 3.4 Change Orders. If Tenant requests any change or addition to the Tenant Work after Landlord's approval of the Construction Drawings for the same, Landlord shall respond to Tenant's request within seven (7) business days after it has been received. If Landlord approves such request, Tenant shall bear the full cost of such change order and no delay in Substantial Completion of the Tenant Work due to the change order shall delay the Commencement Date under the Lease. 52 3.5 Substantial Completion. "Substantial Completion" of each phase of the Tenant Work shall be conclusively deemed to have occurred as soon as that phase has been constructed in accordance with the approved Construction Drawings and approved change orders and is ready to be utilized for its intended purpose, as certified by the Building's Architect, after consultation with Tenant's architect. The issuance of a temporary certificate of occupancy by the proper governmental entity shall be required for Substantial Completion and, if granted, shall be deemed conclusive evidence that Substantial Completion has occurred. Tenant shall obtain a temporary certificate of occupancy for each phase of the Tenant Work. Upon Substantial Completion of all of the Tenant Work, Tenant shall obtain a final certificate of occupancy for the Building. The cost of obtaining the certificates of occupancy shall be payable from the Tenant Improvement Allowance. Notwithstanding the above, Substantial Completion shall be deemed to have occurred even though punch list item remain to be completed in the Tenant Work, the lack of completion of which will not materially interfere with the Permitted Use of the Building. It is understood that the Commencement Date under the Lease is a fixed date and that no delay in Substantial Completion shall result in any extension of the Commencement Date. 3.6 Phased Construction. As contemplated in Section 2.3(b) above, at Tenant's election, the design and construction of the Tenant Work may take place in two (2) separate phases, i.e., one phase involving the Office Improvements and the other phase involving the Remaining Improvements. If Tenant elects to proceed in this fashion, the provisions of this Section 3 shall be deemed to apply to each of the separate phases as and when it is undertaken. 3.7 Landlord's Fee. Tenant shall pay to Landlord, as complete compensation for Landlord's coordination and oversight of the Tenant Work, a fee equal to two percent (2%) of the first One Million Dollars ($1,000,000) of Construction Costs incurred by Tenant and one (1) percent (1%) of all additional Construction Costs incurred by Tenant ("Landlord's Fee"). Landlord's Fee shall be paid to Landlord in installments, with each installment being due and payable at the time each disbursement of the Tenant Improvement Allowance is paid to Tenant under Section 4. Each installment of Landlord's Fee shall be in the amount of the applicable percentage of Landlord's Fee multiplied by the Construction Costs submitted for payment from the Tenant Improvement Allowance and shall be deducted from each payment of the Tenant Improvement Allowance due to Tenant. In the event that the total Construction Costs exceed the Tenant improvement Allowance, the balance of Landlord's Fee for the Office Improvements shall be paid to Landlord within thirty (30) days after Substantial Completion of the Office Improvements and the balance of Landlord's Fee for the Remaining Improvements shall be paid to Landlord within thirty (30) days after Substantial Completion of the Remaining improvements. In all events, however, the entire outstanding balance of Landlord's Fee shall be paid to Landlord no later than thirty (30) days after the Commencement Date. If the total Construction Costs have not been finally determined as of that date, the balance of Landlord's Fee shall nevertheless be paid to Landlord on such date on the, basis of a reasonable estimate of the final Construction Costs and an adjustment shall be made as between Landlord and Tenant when the final Construction Costs have been determined. Landlord may pay from the retainage which it holds under Section 4 any portion of Landlord's Fee which is due and payable. Any failure by Tenant to pay Landlord's Fee when due and payable under this Agreement shall constitute an Event of default under the Lease, subject to the notice and cure provisions of clause (i) of Section 22.1 of the Lease. 53 4. Tenant Improvement Allowance. Tenant shall receive an allowance against the cost of designing, obtaining permits for, and constructing the Tenant Work in the amount of Twenty-Five Dollars ($25.00) per rentable square foot contained within the Building [for a total allowance of Six Hundred Fifty-Three Thousand One Hundred Seventy-Five Dollars ($653,175.00] (the "Tenant Improvement Allowance"). The Tenant Improvement Allowance shall be paid to Tenant or its designee as the construction of the Tenant Work progresses and in proportion to the, completion of such work, subject to retainage as provided for below and to deduction for Landlord's Fee as provided in Section 3.7. Each payment to Tenant or its designee shall be made within thirty (30) days after written request for payment by Tenant (such request not to be made more often than monthly), provided that (a) Landlord's Representative shall have the right to inspect the Tenant Work performed within that period and Landlord shall have the right to withhold payment for any defective or incomplete work noted, and (b) all progress payments in connection with the Tenant Work shall be subject to a ten percent (10%) retainage by Landlord until fifty (50%) of the Tenant Work has been completed and a five percent (50%) retainage by Landlord until Substantial Completion of the Tenant Work has occurred.

All payments of the Tenant Improvement Allowance made by Landlord to Tenant shall be deemed to have been made in trust, for application only to the Construction Costs. At Landlord's option, all checks may be made jointly payable to Tenant and the General Contractor or other party furnishing, labor, materials, or services for the Tenant Work, as the case maybe. The costs subject to payment from the Tenant Improvement Allowance shall not include any interest or other costs of financing or any overhead charge, construction management fee, or other fee to Tenant or any affiliate of Tenant, but shall include Landlord's Fee as provided in Section 3.7. Upon Substantial Completion of the Tenant Work and provided that no Event of Default exists under the Lease (and no event has occurred and is continuing which would constitute an Event of Default upon the giving of notice or the passage of time), the retainage held back by Landlord from the Tenant Improvement Allowance shall be paid to Tenant, less any unpaid balance of Landlord's Fee (which shall be retained by Landlord) and if the total Construction Costs, (plus Landlord's Fee) are less than the Tenant Improvement Allowance, the balance of the Tenant Improvement Allowance shall be credited by Landlord to the first installment or installments of Basic Rent coming due under the Lease until the Tenant Improvement Allowance is exhausted. If the total costs of the Tenant Work (plus Landlord's Fee) are in excess of the Tenant Improvement Allowance, the excess costs shall be borne solely by Tenant and any outstanding balance of Landlord's Fee shall be paid by Tenant to Landlord as provided in Section 3.7. 5.

Tenant further agrees with Lender that Tenant will not voluntarily subordinate the Lease to any lien or encumbrance without Lender's written Consent. Nothing herein shall be deemed to constitute a release by Tenant of Lender or any purchaser to whom Tenant attorns pursuant to Paragraph 3 hereof with respect to the required performance by Lender or such purchaser of any obligation, duty or covenant of Landlord under the Lease arising from and after the date Lender or any such purchaser shall obtain possession of or title to the Premises. 5. In the event that Landlord shall default in the performance or observance of any of the terms, conditions or agreements in the Lease, Tenant shall give written notice thereof to Lender and Lender shall have the right (but not the obligation) to cure such default. Tenant shall not take any action with respect to such default under the Lease, including, without limitation, any action in order to terminate, rescind, or void the Lease or to withhold any rental thereunder, for a period of 10 days after receipt of such written notice by Lender with respect to any such default capable of being cured by the payment of money and for a period of 30 days after receipt of such written notice by Lender with respect to any other such default (provided, that in the case, of any default which cannot be cured by the payment of money and) cannot with diligence be cured within such 30-day period because of the nature of such default or because Lender requires time to obtain possession of the Premises in order to cure the default, if Lender shall 66 proceed promptly to attempt to obtain possession of the Premises, where possession is required, and to cure the same and thereafter shall prosecute the curing of such default with diligence and continuity, then the time within which such default may be cured shall be extended for such period as may be necessary to complete the curing of the same with diligence and continuity). 6. Landlord has agreed in the mortgages that the rentals payable under the Lease shall be paid directly by Tenant to Lender upon the occurrence of a default by Landlord under the Mortgages. Accordingly, after notice is given by Lender to Tenant that the rentals under the Lease should be paid to Lender, Tenant shall pay to Lender, or in accordance with the directions of Lender, all rentals and other moneys due and to become due to Landlord under the Lease, or amounts equal thereto. Tenant shall have no responsibility to ascertain whether such demand by Lender is permitted under the Mortgages, Landlord hereby waives any right, claim or demand it may now or hereafter have against Tenant by reason of such payment to Lender, and any such payment to Lender shall discharge the obligations of Tenant to make such payment to Landlord. 7. Tenant declares, agrees and acknowledges that: a. Lender, in making disbursements pursuant to any agreement relating to the Loan, is under no obligation or duty to, nor has Lender represented that it will, see to the application of such proceeds by the person or persons to whom Lender disburses such proceeds, and any application or use of such proceeds for purposes other than those provided for in such agreement shall not defeat the subordination herein made in whole, or in part; and b. It intentionally and unconditionally waives, relinquishes and subordinates the Lease and its leasehold interest thereunder in favor of the lien or charge of the Mortgages, and that in consideration of this waiver, relinquishment and subordination, specific loans and advances are being and will be made by Lender to Landlord and, as part and parcel thereof, specific monetary and other obligations are being and will be entered into by Landlord and Lender which would not be made or entered into but for said reliance upon this waiver, relinquishment and subordination. 8. This Agreement shall bind and inure to the benefit of the parties hereto, their successors and assigns. As used herein the term "Tenant" shall include Tenant, its successors and assigns; the words "foreclosure" and "foreclosure sale" as used herein shall be deemed to include the acquisition of Landlord's estate in the Premises by voluntary deed (or assignment) in lieu of foreclosure; and the word "Lender" shall include the Lender herein specifically named and any of its successors, participants and assigns, including anyone who shall have succeeded to Landlord's interest in the Premises by, through or under foreclosure of the Mortgage. 67 9. All notices, consents and other communications pursuant to the provisions of this Agreement shall be in writing and shall be sent by registered or certified mail, return receipt requested, or by a reputable commercial overnight carrier that provides a receipt, such as Federal Express or Airborne, and shall be deemed given when postmarked and addressed as follows: If to Lender: With a copy to: If to Tenant: If to Landlord: or to such other address as shall from time to time have been designated by written notice by such party to the other parties as herein provided. 10. This Agreement shall be the whole and only agreement between the patties hereto with regard to the subordination of the Lease and the leasehold interest of Tenant thereunder to the lien or charge of the Mortgages in favor of Lender, and shall supersede and control any prior agreements as to such, or any subordination, including, but not limited to, those provisions, if any, contained in the Lease, which provide for the subordination of the Lease and the leasehold interest of Tenant thereunder to a deed or deeds of trust or to a mortgage or mortgages to be thereafter executed, and shall not be modified or amended and no provision herein shall be waived except in writing by the party against whom enforcement of any such modification or amendment is sought. The use of the neuter gender in this Agreement shall be deemed to include any other gender, and words in the singular number shall be held to include the plural, when the sense requires. In the event any one or more of the provisions of this Agreement shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. This Agreement shall be governed by and construed in accordance with the laws of the {Insert State}. 68 IN WITNESS WHEREOF the parties hereto have placed their hands and seals the day and year first above written.
