1.1

(a)The District leases the Premises from Landlord and Landlord demises the Premises to the District for the term and upon the conditions and covenants set forth in this Lease. The Parties hereby acknowledge that as of the Lease Commencement Date this Lease is a sublease, as Landlord leases the Land (along with additional property) from Celia Properties Limited Partnership, a District of Columbia limited partnership (“Ground Lessor”) under that certain Deed of Lease, by and between Ground Lessor and Landlord, dated as of August 21, 2018 (as amended, the “Ground Lease”). As such, references hereunder to “lease”, “landlord” and “tenant” shall be deemed to mean “sublease”, “sublessor” and “subtenant”, respectively, as applicable, unless context dictates otherwise. Landlord shall cause a final measurement of the Premises and of the Building to be taken upon Landlord’s Substantial Completion of the Base Building Work and the Tenant Improvements, as set forth in the Work Exhibit. Such final measurements shall be: (i) set forth on the Declaration of Delivery, (ii) determined based on the actual measurement of the Project Architect, (iii) in accordance with the BOMA Measurement Standard, and (iv) subject to approval by the District.

(b)In connection with the Ground Lease, Landlord hereby represents and warrants (and covenants, where applicable) to the District that: (i) as of the Lease Commencement Date and at all times during the Lease Term, Landlord’s execution of, and

performance under, this Lease is permitted under the Ground Lease; (ii) any consents that are required to be obtained from any third party to permit Landlord to enter into this Lease have been obtained; (iii) the term of the Ground Lease does not expire until after the expiration of the Lease Term; (iv) during the Lease Term, Landlord shall not (x) terminate the Ground Lease, or (y) cancel or otherwise amend the Ground Lease to shorten its term; and (v) the terms and conditions of the Ground Lease are not incorporated herein.

Parking Facility and the All Access Additional Area Parking Spaces (as defined in, and subject to the terms of Section 2 hereof) 24-hours each day of the Lease Term (including elevator service).

Following the Rent Commencement Date, Landlord shall be responsible for complying with all Laws pertaining to the Building, Common Areas, Base Building Conditions, and Building Structures and Systems, including any required changes to the Building (but not the Premises), at Landlord’s sole cost and expense (meaning that such costs and expenses are already included in Annual Rental and shall not be billed as Additional Rent). Following the Rent Commencement Date, Landlord shall cause all such future changes, additions and/or work to the Building, Common Areas, Base Building Conditions or Building Structures and Systems: (i) to the extent commercially reasonable, to be performed after Building Hours, unless such change, addition and/or work (w) does not interfere in any material, adverse manner with the District’s use and enjoyment of the Premises, as determined by the District in the District’s sole but reasonable discretion, (x) resulted from

the acts or omissions of the District or any of the District’s Agents, (y) is required because of an emergency or (z) involves the build-out of any portion of the Building leased by other non-office tenants; and (ii) if such change, addition and/or work is in the Premises, to be behind walls or above ceilings.

If the District elects to use the Premises in a way that necessitates changes or additions to the Premises in order to comply with Laws solely due to the District’s specific use or occupancy of the Premises, the District shall either cease such use or be responsible for those changes or additions, subject to the certification of the availability of appropriated funds for such purpose.

1.4Subject to the terms and conditions of this Lease (including but not limited to Landlord’s Substantial Completion of the Base Building Work and the Tenant Improvements), Landlord

shall deliver the Premises to the District and the District shall accept the Premises, Building and Land in its “as-is” condition, and in accordance with the terms of this Lease (including without limitation that Landlord shall deliver the Premises to the District pursuant to the terms of the Work Exhibit).

Commencing on the first day of the second Lease Year and on the first day of each subsequent Lease Year thereafter during the Term, the then current rental rate for the MDF Room shall escalate by an amount equal to 2.75% of the rental rate for the immediately preceding Lease Year. As part of the Tenant Improvements, and subject and pursuant to the terms of the Work Exhibit, Landlord shall (i) purchase and install equipment in the MDF Room pursuant to specifications provided by the District (the “MDF Equipment”); (ii) purchase and install a supplemental HVAC unit for the MDF Room pursuant to specifications provided by the District (the “MDF Supplemental HVAC Unit”); and (iii) have the MDF Room separately metered for electricity (the “MDF Sub-Meter”) for the MDF

Equipment and the MDF Supplemental HVAC Unit (the foregoing items (i) through (iii) being, collectively, the “MDF Work”). The Parties acknowledge and agree that the MDF Work shall be paid from the Tenant Improvement Allowance pursuant to the terms of this Lease and the Work Exhibit. Landlord shall procure a separate electrical utility account for the MDF Sub-Meter, and shall not be responsible for payments for such separate account. Landlord shall be responsible for the maintenance and repair of the MDF Room, at its own cost, provided that if any defect or damage to the MDF Room arises from District Negligence the District shall be responsible for the same, pursuant to and in accordance with the terms of Section 9.1 hereof. Subject to Section 15.1, the District shall be responsible for the maintenance and repair of the MDF Equipment. Landlord shall be responsible for the maintenance and repair of the MDF Supplemental HVAC Unit pursuant and subject to the terms of Section 9.6 hereof.

the Fleet Vehicle Spaces, being the “Parking Spaces”), together with a monthly parking permit for each Parking S pace (each, a “Fee Permit”). T he Parking Spaces within the Parking Facility will contain at least 1 3 9 Parking Spaces (no more than 58 of which shall be tandem or stacked) to be allocated among Fleet Vehicle Spaces and Employees Spaces during the planning and development process set forth in Section 2.5 hereto, and all remaining required Parking Spaces shall be provided in the Additional Parking Areas. Subject to Section 2.5 hereto, the f inal allotment of the Fleet Vehicle Spaces and Employee Spaces among the Parking Facility and the Additional Parking Areas shall be determined pursuant to this Section 2 and set forth on the Declaration of Delivery. All Parking Spaces within the Parking Facility and a pproximately fifty (50) of the Parking Spaces within the Additional Parking Areas shall be available for use by the Dist rict and its employees and agents 24 hours each day, 7 days per wee k (the “All Access Additional Parking Spaces”). In addition, the District and its employees and agents shall have access to the Additional Parking Area Parking Spaces, other than the All Access Additional Parking Spaces, during Building Hours. Commencing as of the Rent Commencement Date, the District shall pay as Additional Rent a “Parking Fee” in the monthly amount of $150.00 per Fee Permit for each Fleet Vehicle Space within the Parking Facility and the Additional Parking Areas, which shall be paid i n the same manner as Annual Rental, including in arrears. The Parking Fee shall not be subject to any abatements provided for Annual Rental herein. The Parking Fee shall be subject to an annual escalation commencing at the beginning

of the second Lease Year of 2.5%. “District Parking Rate” mean s the then current Parking Fee as escalat ed by such 2.5% yearly escalations.

Each such agreement shall provide for a monthly parking fee at the then applicable District Parking Rate. As of the Rent Commencement Date, Landlord shall make available to the District up to one hundred and fifty (150) Employee Spaces in the Parking Facility and/or the Additional Parking Areas. If, on or before the date that is six (6) months after the Rent Commencement Date, the District’s Agents have not obtained Fee Permits with Landlord or its parking operator(s) for all one hundred and fifty (150) Employee Spaces, then Landlord may allow other users to obtain parking permits for such unused spaces. Thereafter, Landlord shall provide the District’s Agents with the first opportunity to obtain any vacated Employee Spaces (up to the maximum of one hundred and fifty (150) Employee Spaces) at the District Parking Rate prior to offering any such space to other users.

2.3The District’s use of the Parking Facility and the Additional Parking Areas may be subject to rules and regulations promulgated by Landlord, the Parking Facility operator or the

Additional Parking Area operator(s), as applicable, which are reasonable and in accordance with Laws (to be promulgated and enforced without discrimination against the District) regarding the use of the Parking Facility and the Additional Parking Areas, as applicable, which rules and regulations must be in writing and delivered to the District. If any provision of this Lease conflicts with any provision of such Parking Facility or Additional Parking Area rule s and regulations, such provision of this Lease shall govern. Landlord may undertake a parking study regarding the Parking Facility and the Additional Parking Areas. Based on the results of such study, changes to the Additional Parking Areas may be proposed by Landlord in writing, which shall be subject to the District’s approval, not to be unreasonably withheld, delayed or conditioned. In all events, the District shall deliver to Landlord its written notice of approval or disapproval (and if disapproval the reason(s) therefor must be clearly identified) within ten (10) Business Days after receipt of such proposal. Upon the approval of such new arrangement, the P arties shall execute an acceptable amendment to this Lease to reflect the same.

2.4The contractor or contractors operating the Parking Facility and the Additional Parking Areas during the Lease Term shall each be a Small Business Enterprise (“SBE”) or a Certified Business Enterprise (“CBE”), as such terms are defined under D.C. Official Code Section 2-218.02, as amended from time to time; provided, however, that in the event less than three (3) SBE or CBE parking operators with experience managing a parking facility of similar size and of a similar quality to the Parking Facility conduct business in the

District of Columbia, Landlord shall not be required to hire a SBE or CBE parking operator, but shall use good faith, commercially reasonable efforts to do so.

2.5Notwithstanding anything to the contrary in this Section 2, during the design and development of the Base Building Work and Tenant Improvements pursuant to the Work Exhibit, Landlord may suggest to the District a change to the Parking Facility that would allow the Parking Facility to accommodate additional Parking Spaces. Provided that such change does not reduce the number of Parking Spaces available to the District in the Parking Facility below 139 spaces (no more than 58 of which shall be tandem or stacked), the District shall not unreasonably withhold, delay or condition its approval of such change. In such event, if the number of spaces in the Parking Facility provided to the District increases above 139 (no more than 58 of which shall be tandem or stacked), the number of spaces required in the Additional Parking Areas shall be reduced by such number of additional Parking Spaces (above 139) in the Parking Facility, and any such adjustment shall be set forth on the Declaration of Delivery. Further, the District understands that Landlord or its affiliates are developing the areas adjacent to the Land, all as shown on “Exhibit K” attached hereto and made a part hereof (the “Development Area”). As such, from time to time, upon 60-day prior written notice to the District, Landlord may change the location of the Additional Parking Areas and provide Parking Spaces in lieu of the then current location of such Additional Parking Areas, without District approval, provided that such new or modified locations are among the locations

By executing this Lease, Landlord acknowledges and pre-approves occupancy for such purposes by any District of Columbia agency or instrumentality as the District may elect during the Lease Term. Substitution of an agency or instrumentality shall not constitute an assignment or sublet or be subject to Landlord’s approval, so long as the substituted agency uses the Premises for the Permitted Use. The District shall endeavor to provide at least 30 days prior written notice to Landlord of any such substitution, but any failure to provide such notice shall not constitute a default under this Lease. The District shall comply with all Laws applicable to it concerning the use, occupancy and condition of the Land, Building or Premises and all machinery, equipment, furnishings, fixtures, and improvements therein, all of which shall be complied with in a timely manner, provided that the District shall not be required to construct or alter the elements of the Base Building Conditions or Building Structures and Systems within the Premises unless required by reason of either (i) the District’s particular use of the Premises, or (ii) any Alteration. If the District is so required to construct or alter any elements of the Base Building Conditions or Building Structures and Systems as aforesaid, all such construction or alteration shall be Alterations and shall be subject to the terms and provisions of Sections 8.2 and 8.3 of this Lease.

therein (other than a certificate of occupancy), then the District shall obtain and keep current such permit or license; provided, however, that Landlord shall be responsible for obtaining any necessary licenses or permits to perform the Tenant Improvements and the Base Building Work, and Landlord shall ensure that the Tenant Improvements and Base Building Work comply with all Laws, and, upon Substantial Completion of the same, Landlord shall deliver the appropriate certificate(s) of occupancy to the District.

Nothing in this Section 3.1 is intended to prevent Landlord from pursuing remedies against the District pursuant to Section 18.1 hereof for any breaches of the foregoing provisions.

3.2The District shall pay before delinquency any business, rent or other taxes or fees that are now or hereafter levied, assessed or imposed directly upon the District by any governmental authority due to its use or occupancy of the Premises, the conduct of the District’s business at the Premises or the District’s equipment, fixtures, furnishings, inventory or personal property, subject to the certification of the availability of appropriated funds for such purpose and Section 26.1 hereof. If any such tax or fee is enacted or altered so that such tax or fee is levied against Landlord or so that Landlord is responsible for collection or payment thereof, then the District shall pay such tax or fee with the monthly payment of Annual Rental next becoming due and payable, subject to the certification of the availability of appropriated funds for such purpose and Section 26.1 hereof.

Subject to the Anti-Deficiency Acts, the District shall promptly cure any

(a)Notwithstanding anything in this Section 7 to the contrary, (i) Landlord hereby grants to the District a rental abatement of Annual Rental payable hereunder in the total amount of $18,105,241.42, which is equal to the total of (x) 10 months of Annual Rental in the amount of $11,276,595.00 plus (y) the additional rental abatement in the amount of $6,828,646.42 referenced in Section 23.3(ii) hereof (such total amount, the “Landlord Credit”), which shall, at the District’s election, be applied toward (A) Annual Rental commencing on the Rent Commencement Date, and/or (B) any obligation the District may have to pay for any of the Tenant Improvements (in excess of the Tenant Improvement Allowance) in accordance with the Work Exhibit; and (ii) in the event Landlord does not deliver the Declaration of Delivery for execution by the Parties within 45 calendar days after the satisfaction of Landlord’s Delivery Obligations, then for each month or partial month following such 45 day period that Landlord fails to deliver the Declaration of Delivery for execution by the Parties, the District shall be entitled to an abatement of Annual Rental and Additional Rent equal to $2,000 per day for each day that Landlord does not deliver the Declaration of Delivery after such 45 day period. Landlord shall have satisfied its obligation to deliver the Declaration of Delivery if it delivers a

fully completed Declaration of Delivery to the District, even if the District disputes any provision thereof. The District may be entitled to an additional rent abatement pursuant and subject to the terms of the Work Exhibit.

(b)In addition to the Tenant Improvement Allowance, any time between the 10th and 12th Lease Years of the Lease Term, the District shall be entitled to a Premises improvement allowance from the Landlord in the total amount of $2,250,000.00. Such allowance shall be applied by the District towards refreshing the Premises (e.g. paint and carpet) (the “Premises Refresh Allowance”) by providing written notice to Landlord not later than the end of the 11th Lease Year; provided that not less than nine (9) months and not more than twelve (12) months prior to the expiration of the 11th Lease Year, Landlord shall provide the District with written notice inquiring as to whether the District will elect to utilize the Premises Refresh Allowance. If Landlord fails to timely deliver such notice, then the District may elect to provide its notice to Landlord as to the application of the Premises Refresh Allowance after the 11th Lease Year so that the District is afforded no less than nine (9) months and no more than twelve (12) months to determine how to apply the Premises Refresh Allowance and, in such event, the Premises Refresh Allowance may be applied by the District after the 12th Lease Year. In no event shall any amount be due or payable by the District to Landlord in connection with the amortization or other repayment of the Premises Refresh Allowance.

7.5 Real Estate Taxes.

(a)The District shall pay to Landlord Real Estate Taxes assessed

EXECUTION VERSION

against the Property and paid by Landlord each Lease Year as set forth below. T he initial real estate taxes shown on Section of II(8)(c)(5) of DC DGS Form L-102 are to be paid by the District as a component of Annual Rental (the “Initial Real Estate Taxes”). In the event that in any Lease Year hereunder the total amount of Real Estate Taxes assessed against the Property exceeds the Initial Real Estate Taxes, then the District shall pay the District’s Proportionate Share of such excess amount of such Real Estate Taxes (“Tax Increases”) to Landlord as Additional Rent. The amount of such Tax Increases shall be due and payable to Landlord by the District semi-annually within 90 days of the date of receipt by the District of a statement from Landlord, which statement shall include copies of all actua lly paid real estate tax bills (and Landlord’s evidence of the payment thereof), for such applicable semi-annual District of Columbia real property tax billing cycle (each, a “Tax Statement”). The District’s Proportionate Share of Real Estate Taxes as of the Rent Commencement D ate is set forth in Section III(17) of DC DGS Form L-102. Notwithstanding the foregoing or anything else contained in this Lease, Landlord shall not be permitted to charge the District (and the District shall not be obligated to pay) for any Tax Increases for any semi-annual District of Columbia real property tax billing cycle if Landlord fails to first deliver to the District a Tax Statement by the date that is 12 0 days after the due date for Landlord’s payment of real estate taxes under such semi-annual District of Columbia real property tax billing cycle. For any partial Lease Years, Tax Increases shall be appropriately prorated based upon the number of days in such partial Lease Year within the semi-annual District of

Columbia real property tax billing cycle. Notwithstanding any provision of this DC DGS Form L-105 to the contrary, the District and Landlord stipulate that Real Estate Taxes for the first Lease Year are the amount set forth in Section II(8)(c)(5) of DC DGS Form L-102, and that the District has no audit right with regard to Initial Real Estate Taxes or Tax Increases other than to confirm the calculation of Tax Increases, and to review the real estate tax bills generated by the taxing authority and Landlord’s evidence of its payment of the same.

(b)For the purposes of this Section 7.5, the term “Building” shall be deemed to include the Land, the roof of the Building and any extensions therefrom, and, to the extent that such elements exist, any balconies extending from the Building, and any driveways or sidewalks. The District recognizes that prior to the Rent Commencement Date, Landlord shall have created a separate A&T Lot for the Property. Thereafter, as part of the development of the Development Area, Landlord shall have the right to change the A&T Lot provided that the same shall not result in the District being required to pay any more Real Estate Taxes or Tax Increases then it otherwise would have been required to pay hereunder absent such change to the A&T Lot.

(c)“Real Estate Taxes” means: (i) all ad valorem real property taxes, vault space rental fees, and any special assessment, foreseen or unforeseen (including without limitation any assessments imposed in connection with business improvement or similar districts), which are imposed upon Landlord in connection with its ownership or control of the Property; and (ii) any other present or future taxes or

3924 Minnesota Avenue NE

EXECUTION VERSION

charges that are imposed upon Landlord in connection with the Property or assessed against the Property that are in express substitution for ad valorem real property taxes. Real Estate Taxes shall not include any: (A) fines, penalties or interest on any Real Estate Taxes, except to the extent caused solely by the District’s failure to pay the District’s Proportiona te Share of Real Estate Taxes pursuant to the terms of this Lease; (B) costs incurred by Landlord to challenge the tax valuation or assessment of the Building, Land or Property, or otherwise challenge any aspect of Real Estate Taxes; (C) “ballpark t ax es”, arena taxes or similar, including without limitation charges or fees imposed upon Landlord in connection with the development, financing, construction, operation, maintenance and/or use of any sports or entertainment stadium, arena or comp lex (or similar) in the District of Columbia; (D) capital gains, corporation, unincorporated business, income, net income, profits, excess profit, estate, inheritance, transfer, recordation, gi ft, franchise or license fees/taxes; (E) hotel or business entity fees (unless such taxes or fees replace or supplement the current system of real property taxes in effect as of the date hereof); (F) any Real Estate Ta xes under a Separate Assessment; or (G) Real Estate Taxes resulting from a Tax I ncrease due to a combination of real property tax assessment parcels that includes the real property tax assessment parcel upon which the Building is situated.

(d)In the event Landlord receives a refund for any Real Estate Taxes paid during the Lease Term as a result of challenging the tax valuation or assessment of the Building, Land or Property, the District shall be entitled to receive a rent abatement equal to the

District’s Proportionate Share of such refund in the form of a rent abatement (the “District Refund Abatement”). Within sixty (60) days of receiving funds in an amount equal to the Real Estate Tax refund, Landlord shall deliver written notice to the District of the District Refund Abatement (together with supporting documentation). The District shall then deliver written notice to Landlord as to which monthly payment of Annual Rental and Additional Rent it elects the District Refund Abatement to be applied. Notwithstanding any provision in this Lease to the contrary, the District Refund Abatement shall be in addition to any other abatement of rent provided or permitted under this Lease.

7.6 Operating Costs.

(a)The Annual Rental for each entire and partial Lease Year includes the Initial Operating Costs. Commencing on the first day of the second Lease Year, and the first day of each subsequent Lease Year thereafter during the Lease Term (each such date being the “Adjustment Date”), the then current Operating Costs shall be increased to an amount equal to the District’s Proportionate Share of Operating Costs due and payable in the preceding Lease Year, multiplied by a fraction, the numerator of which shall be the CPI as of the Adjustment Date (or the most recently issued CPI prior to the Adjustment Date), and the denominator of which shall be the CPI as of 12 months prior to the Adjustment Date (or as of 12 months prior to the most recently issued CPI prior to the Adjustment Date, or if in the second Lease Year, the most recently issued CPI prior to the Rent Commencement Date); provided, however, in no event shall such CPI-based increase exceed 5% of the then

PAGE 27 OF 135(as modified) DC DGS FORM L-105 (3/2018)

3924 Minnesota Avenue NE

US 167835565v6

EXECUTION VERSION

current Operating Costs (as adjusted, the “Operating Cost Increases”). The Operating Cost Increases shall be payable as Additional Rent in the same manner and timing as Annual Rental, including in arrears. For any partial Lease Year, all Operating Costs shall be appropriately prorated. The District’s Proportionate Share of Operating Costs as of the Rent Commencement Date is set forth in Section III(17) of DC DGS Form L-102. Promptly after the publication of the CPI for the Adjustment Date or the most recently issued CPI prior to the Adjustment Date, Landlord shall send written notice to the District of the amount of the CPI change for each successive Lease Year, including the calculation of the Operating Cost Increase and the change in CPI, and such increase, if any, shall apply as of the Adjustment Date for such Lease Year.

(b)The Parties acknowledge and agree that as part of the Base Building Work, the Premises will be sub-metered for electricity.

8. Construction of Tenant Improvements and Base Building Work; Alterations; Delivery Date

8.1The design and construction of the Base Building Work and the Tenant Improvements shall be performed and completed by Landlord in accordance with Section 8.4 hereof and the Work Exhibit.

8.2After the Substantial Completion of the Tenant Improvements, the District shall not make or permit anyone to make Alterations without the prior written consent of Landlord, (i) which consent may be withheld or granted in Landlord’s sole and absolute

discretion with respect to Alterations which may affect any aspect of the Base Building Conditions or Building Structures and Systems, and (ii) which consent shall not be unreasonably withheld, conditioned, or delayed with respect to non-structural Alterations. Alterations that may adversely affect Base Building Conditions or the Building Structure and Systems shall be deemed to include, without limitation, any Alteration that will or may necessitate any changes, replacements or additions to the columns, slabs or other structural elements of the Building, or to the fire protection, water, sewer, electrical, mechanical, plumbing or HVAC systems of the Premises or the Building, that result in the need for changes to the Building to comply with applicable Laws or which will impose additional costs on the operation of the Building and/or the Premises. With respect to any Alteration requiring Landlord consent, the District shall not proceed with such Alteration until the parties have executed a mutually satisfactory amendment to this Lease setting forth the scope of work, the cost therefor, and confirming the District’s proof of funding for such costs, as well as any other terms and conditions agreed to by the parties. Notwithstanding the foregoing, the District shall have the right, after providing ten (10) days’ prior written notice to Landlord, but without the necessity of obtaining Landlord’s consent, to re-carpet, re-paint or to make any cosmetic or decorative nonstructural Alterations in or to the Premises. All Alterations shall be constructed at the District’s election and expense, subject to the certification of the availability of appropriated funds for such purpose, and once commenced shall be undertaken and completed by the District, in compliance with applicable Laws and lien free. The

EXECUTION VERSION

District shall not permit any mechanic’s lien to be filed against the Premises, Building or the Land for work claimed to have been done for, or materials claimed to have been furnished to, the District. If a mechanic’s lien is filed against the Premises, Building or the Land for work claimed to have been done for, or materials claimed to have been furnished to, the District, and the District does not promptly remove or discharge the same, Landlord shall have all rights and remedies at law or in equity including for breach of contract. Landlord shall not be liable for any and all claims, losses, expenses, and damages resulting from or arising out of any Alterations by the District. If Landlord gives its consent to the making of any Alteration, such consent shall not be deemed to be an agreement or consent by Landlord to subject its interest in the Premises or the Building or the Land to any liens that may be filed in connection therewith. The District acknowledges that any Alterations are accomplished for the District’s account, and, other than an Alteration performed by Landlord for the District and subject to the terms and conditions of a work exhibit, work agreement or Section 11.3 hereof for such Alterations, Landlord shall have no obligation or responsibility in respect thereof. Landlord’s approval of any plans and drawings (and changes thereto) regarding any Alterations, other than any Alteration performed by or on behalf of Landlord for the District and subject to the terms and conditions of a work exhibit, work agreement or Section 11.3 hereof for such Alterations, shall not constitute Landlord’s representation that such approved plans, drawings, changes or Alterations comply with Laws. Any deficiency in design or construction of any Alteration (other than an Alteration

performed by Landlord for the District and subject to the terms and conditions of a work exhibit, work agreement or Section 11.3 hereof for such Alterations) shall be solely the responsibility of the District.

8.3If any Alterations that require Landlord consent are made without the prior written consent of Landlord, Landlord shall have the right to require the District to restore the Premises and the Building to their condition immediately prior thereto, subject to the District certifying the availability of appropriated funds for such purpose. If the District does not so restore the Premises and the Building the same shall constitute an Event of Default hereunder and Landlord shall have all rights and remedies available at law or in equity including for breach of contract. All Alterations to the Premises or the Building made by either Party shall immediately become the property of Landlord and shall remain upon and be surrendered with the Premises as a part thereof at the expiration or earlier termination of the Lease Term, except that the District shall be required to remove any Alterations that Landlord requires the District to remove as a condition of its consent to the installation of such Alterations under Section 8.2 hereof, so long as Landlord notified the District at the time of its approval of such Alterations that the District shall be required to remove the same (in order that the District may include the costs of such removal in its budgetary process); provided, however, the District shall have the right to remove, prior to the expiration or earlier termination of the Lease Term, all movable furniture (including systems furniture), furnishings and equipment installed in the Premises solely at the expense and discretion of the District.

EXECUTION VERSION

The District shall repair any damage and injury to the Premises or the Building caused by such removal subject to the District certifying the availability of appropriated funds for such purpose. If the District does not so repair any damage and injury to the Premises and the Building the same shall constitute an Event of Default hereunder and Landlord shall have all rights and remedies available at law or in equity including for breach of contract. If such furniture (including systems furniture), furnishings and equipment are not removed by the District at the expiration or earlier termination of the Lease Term, the same shall at Landlord’s option (i) be deemed abandoned, or (ii) become the property of Landlord to be surrendered with the Premises as a part thereof.

8.4

(a)Subject to a day for day extension for each day of delay caused by a Force Majeure Event and any day of District Delay, in the event that Landlord does not meet Landlord’s Delivery Obligations on or before December 31, 2022 (the “Outside Delivery Date”), the District shall be entitled to a credit against Annual Rental and any Additional Rent for each day beyond the Outside Delivery Date that Landlord’s Delivery Obligations have not been performed by Landlord.

(b)Subject to a day for day extension of the Outside Delivery Date for each day of delay caused by a Force Majeure Event (not to exceed 120 days) and each day of District Delay, in the event that the date of Landlord’s satisfaction of Landlord’s Delivery Obligations has not occurred on or before the date that is two hundred and ten (210) days after the Outside Delivery Date (the

“Outside Delivery Termination Date”), the District shall have the right to terminate this Lease upon written notice to Landlord at any time thereafter (provided Landlord has not yet satisfied Landlord’s Delivery Obligations). In the event of any such termination, this Lease shall be of no further force and effect, and neither Party shall have any further obligation to the other hereunder, subject to Section 24.14 hereof.

(c)In the event that the District does not exercise its termination right pursuant to paragraph (b) of this Section 8.4, the District shall be entitled to a credit against Annual Rental equal to two days of Annual Rental for each day beyond the Outside Delivery Termination Date until Landlord’s Delivery Obligations have been performed by Landlord. For the sake of clarity, the rent credit provided for in this paragraph (c) as of the Outside Delivery Termination Date is in lieu of and not in addition to the rent credit provided for in paragraph (a).

9.MAINTENANCE AND REPAIRS

9.1Notwithstanding any other provision of this Lease, but subject to Sections 9.2, 16 and 17 hereto, Landlord, at its sole cost and expense (meaning that such costs and expenses are already included in Annual Rental and Operating Cost Increases and shall not otherwise be billed as Additional Rent), shall promptly make all repairs, perform all maintenance, and make all replacements in and to the Land, the Building, Building structures and systems, and, except as set forth below, the Premises (including elevator lobbies and bathrooms constituting a portion of the Premises) that are necessary or desirable to keep the same: (a) in good

The District shall maintain and repair the Premises (excluding elevator lobbies and bathrooms constituting a portion of the Premises) as provided in the next sentences. The District shall provide written notice to Landlord of any material defect in or material damage to the Premises, and Landlord shall inspect such condition. If the defect or damage is caused by the negligence or willful misconduct of the District or its employees (as determined by the judgment of a court of competent jurisdiction in the event the District disputes that the District or its employees were negligent or engaged in willful misconduct), the District shall be responsible for cost of the repair. If the District does not dispute that it is responsible for the cost of the repair or replacement, Landlord shall provide the District with an invoice for the cost of the necessary repair or replacement for the District’s approval, which invoice may include a Landlord service fee not to exceed 3.0% of such cost. If such invoice is approved by the District (or if Landlord is responsible for the repair or replacement), Landlord shall effect the repair or replacement, and, if applicable, the District shall pay any such approved invoice following completion of the subject work and within thirty (30) days after receipt of such invoice. If such invoice is not approved by the District, the District shall be responsible for undertaking the needed repair or replacement. The District shall suffer no waste or injury to any part of the Premises, and shall, at the expiration or earlier termination of the Lease Term, surrender the Premises in an order and

condition equal to its order and condition on the Rent Commencement Date, subject to ordinary wear and tear, Landlord’s repair and maintenance obligations, and Section 16.

9.2Except as otherwise provided in Sections 15.2 and 16, the District shall be responsible for all injury, breakage and damage to the Premises and to any other part of the Building or the Land to the extent caused by District Negligence. At all times, subject to Section 14, Landlord shall be liable for all injury, breakage and damage to the Premises and, if applicable, the MDF Equipment and the MDF Supplemental HVAC, resulting from a failure of the Base Building Conditions or Building Structures and Systems, except to the extent arising solely due to District Negligence. The District shall endeavor to give Landlord prompt notice of any known defects or damage to the structure of, or equipment or fixtures in, the Building or any part thereof.

9.3 Landlord shall ensure that the Building shall be managed, operated and maintained in accordance with the standards of quality followed in first class office buildings in Washington, D.C., and in full compliance with all applicable Laws. If Landlord engages a third party property management company, the District shall have the right to approve the same, which approval shall not be unreasonably withheld, conditioned or delayed. The District shall approve or disapprove such proposed management company within ten (10) Business Days after delivery to the District of a written request for such approval and be deemed to have approved the same if it does not timely deliver written notice to Landlord of its approval or disapproval.

9.4 Notwithstanding anything in this Lease to the contrary, the Parties hereby agree that Landlord’s entry into the Premises shall be subject to the District’s security requirements.

9.5 The District’s financial obligations under this Section 9 are subject to Section 26.1 hereof.

9.6 Supplemental HVAC. Landlord shall provide repair and maintenance of the District’s supplemental HVAC equipment and systems associated with the Premises (including, if applicable, the MDF Supplemental HVAC Unit) subject and pursuant to the following provisions: Landlord shall solicit bids for a contract for such services to be provided by a contractor engaged by Landlord (a “Supplemental HVAC Services Agreement”). Within 30 days after the Rent Commencement Date, provided Landlord has received all of the information from the District necessary to obtain bids, Landlord shall deliver to the District, pursuant to the provisions of Section 24.2 hereof, the solicitation responses for the bidding related to the Supplemental HVAC Services Agreement and the contractor that Landlord believes is most responsive with respect to price and performance. The costs under any such contract shall be subject to prior approval by the District, and such costs may include a fee payable to Landlord in connection therewith in the amount of 3% of the contract amount (without such fee). Such payments, including any 3% Landlord fee associated therewith shall be paid on a monthly basis as Additional Rent under the Lease (and pursuant to the same terms and schedule as the Annual Rental, including in arrears). The Supplemental HVAC Services Agreement contract amount

shall not include the cost of any non-preventative maintenance repairs of, or replacements to, the District’s supplemental HVAC equipment, and any such work and the costs thereof proposed by Landlord or the contractor shall be subject to the District’s prior written approval. Renewals of such Supplemental HVAC Services Agreement may be negotiated by the parties thereto; provided, however, that the District shall not be obligated to pay any costs thereof unless and until it has approved any such cost, and has certified the availability of appropriated funds for such purpose. In the event a Supplemental HVAC Services Agreement is scheduled to expire within 90 days or is terminated, Landlord shall notify the District of the same pursuant to the provisions of Section 24.2 hereof and, upon the District’s written approval, Landlord shall solicit bids for a new contract within 30 days of the District’s approval to do the same (in which event the terms of this section shall continue to apply to any subsequent Supplemental HVAC Services Agreement).

10.SIGNS

Landlord, at its sole cost and expense, shall provide and install exterior signage, one Building standard directory strip in the Building’s main lobby, and initial suite entry signage for the Premises, each using the standard graphics for the Building.

Official Code § 1-204.51, as may be amended from time to time (pertaining to prior Council approval of contracts in excess of $1,000,000.00 in any 12-month period). If the District approves an Additional Cost Approval (including Council approval, if applicable), after Landlord completes the Additional Services pursuant to the Scope of Work, Landlord shall deliver an invoice for the actual cost therefor to the District, which invoice may not exceed the Additional Services Cost and shall be on an “open book” basis. The District shall pay to Landlord such actual cost of the Additional Services, in arrears, as Additional Rent with the next payment of Annual Rental coming due and payable after Landlord has delivered such actual cost invoice to the District. If Landlord’s actual costs exceed the Additional Services Cost, such excess costs shall be the sole liability and responsibility of Landlord; in no event shall the District be liable for any amount in excess of the previously approved Additional Services Cost without an Additional Cost Approval for such excess.

The District shall not, however, implement such self-help sooner than five (5) Business Days after the District delivers notice to Landlord of the District’s intention to commence its self-help remedy if the Interruption is not previously cured. Provided that the Interruption is not caused by District Negligence, Landlord shall reimburse the District for the District’s reasonable costs to address the Interruption within ten (10) Business Days following written demand by the District therefor (such demand to include copies of invoices). Landlord shall be deemed to have consented to the District performing any alterations or replacements to address the Interruption. The District shall provide verbal notice to Landlord of any Interruption of which the District has actual knowledge. Due to the nature of the Interruption, the Parties acknowledge and agree that the District may not be able to provide advance notice to Landlord of the steps taken by the District to address the Interruption. The Parties agree that Landlord may enter the Premises to observe the actions taken by the District, subject to any District security requirements. The District shall be responsible for the repair of all injury, breakage and damage to the Premises resulting from an Interruption to the extent caused by District Negligence.

12.2With respect to any Interruption not caused by District Negligence, if the District informs Landlord that the District elects not to address the Interruption pursuant to the foregoing Section 12.1, then (i) Landlord shall promptly address the Interruption in order to avoid or mitigate against interruption of the District’s operations within the Premises, and (ii) the District

shall be entitled to an abatement of Annual Rental and Additional Rent on a per diem basis in the proportion which the affected area bears to the total Premises. Such abatement shall begin on the first Business Day of the Interruption and shall continue for each day such Interruption continues (and such abatement shall end as to each area affected when the ability to use and occupy is fully restored to such area). If such Interruption continues for ten (10) continuous Business Days, then Landlord shall deliver to the District within the next five (5) Business Days a reasonably detailed written plan to remedy and end the Interruption. If Landlord fails to timely deliver such plan or if the District does not approve such plan, in its reasonable discretion, then District shall have the right to terminate this Lease within thirty (30) calendar days of the expiration of such five (5) Business Day period. If the Interruption continues for 90 consecutive calendar days, then the District shall have the right to terminate this Lease by written notice to Landlord at any time following the 90 th day of such Interruption; provided, however, if such Interruption ceases prior to delivery by the District of such notice of termination or prior to the effective date of such termination, such notice of termination shall be deemed revoked and of no further force and effect.

13.INSPECTION

13.1Subject to the District’s security requirements and upon reasonable prior notice which need not be in writing (recognizing that no such limitations shall apply in the event of a situation reasonably determined by Landlord to be an emergency affecting the Premises or the Building or the health or safety of tenants or visitors to the

Premises or Building (any such event being referred to herein as an “Emergency Condition”)), the District shall permit Landlord, its Representatives, and the holder of any mortgage, to enter the Premises without charge therefor and without diminution of the rent payable by the District in order to examine, inspect or protect the Premises; to make such alterations and/or repairs to the Base Building Conditions and Building Structures and Systems as in the judgment of Landlord may be deemed necessary or desirable; or to show the Premises to prospective lenders or purchasers; or, if the District has given notice to Landlord that it intends to vacate the Premises or if during the last two (2) Lease Years of the Lease Term, then to exhibit the same to brokers and prospective tenants. Landlord shall endeavor to minimize disruption to the District’s normal business operations in the Premises in connection with any such entry. Except for an Emergency Condition, Landlord shall use commercially reasonable efforts not to interrupt, delay or disrupt the District’s normal business operations in the Premises without reasonable, prior notice to the District of its intent to do so.

14.INSURANCE

14.1Landlord shall carry and maintain special form property insurance (ISO or its equivalent), with 100% replacement cost coverage and an agreed amount endorsement, covering the Building (including the Tenant Improvements constituting fixtures) and Landlord’s property therein, in an amount required by its insurance company to avoid the application of any coinsurance provision. Such insurance shall include extended coverage and other endorsements of the kinds normally

required by institutional lenders and that permit insurance proceeds to be used by Landlord for the repair and restoration of the Building (including the Tenant Improvements constituting fixtures). Landlord also agrees to carry and maintain commercial general liability insurance with a minimum limit of liability in the amount of $3,000,000 for personal injury or death of persons occurring in or about the Building (including the Premis e s). Landlord may elect to carry such other additional insurance or higher limits as is consistent with the insurance held by owners of comparable of fice buildings in Washington, D C. Landlord shall (i) cause the “District of Columbia, as its interests may appea r” to be added as a loss payee as to property insurance (for that portion of the Building not used by or leased to third parties) and an additional insured as to liability insurance, (ii) provide for a waiver of subrogation in favor of the District of Columbia, and (iii) cause its insurance carriers to provide the District of Columbia with 10 days’ prior written notice in the event of policy cancellation due to a non-payment of premium and 30 days’ prior written notice in the event of a cancellation for any other reason, on all insurance policies required to be carried by Landlord under th is Lease. Upon receipt of any check for insurance proceeds requiring the endorsement of the District (because of its status as a loss payee), the District shall promptly endorse the same so that such proceeds may be delivered either (i) upon request by Mortgagee to Mortgagee or (ii) if there is not then a Mortgagee or Mortgagee does not desire to hold such funds, so long as Landlord is performing its repair or restoration obligations set forth in this Lease, to another escrow agent reasonably selected by Landlord,

which depository shall hold such funds and provide the same to Landlord on a progress payment basis as Landlord completes any repairs to the Building and/or the Premises required or reasonably appropriate in connection with the casualty for which such insurance proceeds were delivered. If as a result of being named loss payee on such insurance, the District receives any insurance proceeds, it shall (i) promptly upon receipt thereof deliver the same to the Mortgagee if Mortgagee has requested the same or, so long as Landlord is performing its repair or restoration obligations set forth in this Lease, to the alternative depository as described in the previous sentence to allow Landlord to undertake the repair of the Building and/or the Premises with such funds, and (ii) if it is holding any such funds upon the expiration or earlier termination of this Lease immediately deliver the same to Landlord.

14.2 Landlord acknowledges that the District does not maintain any insurance policy insuring against liability or loss, damage or injury to property, relevant to this Lease, and therefore a waiver of subrogation in favor of Landlord by the District does not apply. The District shall be responsible for the repair of all injury, breakage and damage to the Premises and to any other part of the Building or the Land to the extent caused by District Negligence. The District shall not conduct or permit to be conducted any activity or place any equipment or other item in or about the Premises or the Building that will increase the rate of the above described insurance on the Building. Upon notice of any increase, the District shall immediately cease the activity that caused the increase, or agree to pay said increase subject to the District certifying

the availability of appropriated funds for such purpose.

14.3Prior to the Lease Commencement Date, and subsequently on every anniversary of the Lease Commencement Date or as requested by the District, Landlord shall deliver to the District such certificates of insurance, endorsements and declarations pages as the District may reasonably request confirming that (i) the insurance coverage amounts and policies required hereunder are in force with premiums paid, and (ii) that such policies shall not expire within 30 days from the date of such delivery by Landlord. All insurance required hereunder shall be primary and noncontributory and purchased from carriers authorized to do business in the District of Columbia and possessing an A- or better policyholders’ rating and a minimum Class VIII financial size category as listed at the time of issuance by A.M. Best Insurance Reports or a similar rating publication. At all times during the Lease Term, Landlord agrees to maintain the insurance coverage required in this Section 14. Landlord shall provide the District with written notice of cancellation of any insurance required of Landlord hereunder. The District’s review or approval of any certificates of insurance, endorsements or other documents provided under this Section 14 are for the District’s benefit only, and any such review or approval by the District shall not be deemed to constitute confirmation or ratification that Landlord has satisfied, or a waiver of, the insurance requirements under this Section 14 as to the Property or any portion thereof.

14.4 Notwithstanding anything in this Lease to the contrary, Landlord hereby waives, and releases the District

and its Agents of and from, any and all rights of recovery, claims, or causes of action, whether by subrogation or otherwise, against the District or its Agents for any liability, loss or damage that may occur to the Property (including the Premises), Landlord’s property or any leasehold improvements (regardless of cause or origin, including the negligence of any of the District or its Agents), which loss or damage is insured against or is required to be insured against by Landlord hereunder. All insurance policies against loss or damage to property and business interruption or rent loss shall be endorsed to provide that any release from liability of, or waiver of claim for recovery from, another person entered into in writing by the insured thereunder prior to any loss or damage shall not affect the validity of such policy or the right of the insured to recover thereunder. Such policies shall also provide that the insurer waives all rights of subrogation that such insurer might have against such other person (i.e., a waiver of subrogation shall be applied in favor of the District). Landlord hereby waives all claims for recovery from or against the District for any loss or damage to any of its property, or damages as a result of business interruption or rent loss, insured under a valid policy to the extent of any recovery collected under such policies or any recovery that would have been collected under insurance policies required to be, but not, carried hereunder. To the extent not inconsistent with other provisions of this Lease and applicable law, Landlord shall not be obligated to insure, and shall not assume any liability of risk of loss for, the District’s property, including any such property or work of the District’s subtenants or occupants. Landlord shall also have no obligation to carry insurance against any loss suffered

by the District, subtenants or other occupants due to interruption of the District’s or any subtenant’s or occupant’s business.

15.LIABILITY OF LANDLORD and the DISTRICT

15.1Except as otherwise expressly provided in this Lease, neither Landlord nor its Representatives shall be liable to the District or its Agents for any damage, injury, loss or claim based on or arising out of any fire, robbery, theft, vandalism, mysterious disappearance or any other casualty, or the actions of any other person or entity, unless such liability arises from the negligence or willful misconduct of Landlord or its Representatives. Landlord shall be liable to the District, and shall indemnify, defend and hold the District harmless from, any damage, injury, loss or claim based on or arising out of this Lease, or any agreement executed in connection with this Lease, including claims for personal injury, death or property damage, if the same is due to the negligence or willful misconduct of Landlord or its Representatives.

15.2Neither the District nor its Representatives shall be liable to Landlord or its Representatives, for any damage, injury, loss or claim based on or arising out of any cause whatsoever to the extent such damage, injury, loss or claim is (i) covered by Landlord’s insurance or would be covered by Landlord’s insurance to the extent required under this Lease or (ii) is due, in whole or in part, to the acts or omissions of Landlord or its Representatives. Under no circumstance shall the District or Landlord (or their respective Agents or Representatives) be liable to the other for any exemplary, punitive, consequential or indirect

damages in connection with, arising under or relating to this Lease, provided, however, that this limitation shall not apply with regard to Section 16.3 or any claim arising under the False Claims Act.

15.3[Intentionally Deleted].

16.DAMAGE OR DESTRUCTION

16.1(a)If the Premises or the Building are totally or partially damaged or destroyed (a “Casualty”), then Landlord shall diligently repair and restore the Building and Premises (including Tenant Improvements constituting fixtures); provided, however, that notwithstanding anything to the contrary in this Lease in such event, (i) the District shall have the right to terminate this Lease on sixty (60) days’ prior written notice given within thirty (30) days of the date of the Casualty if, in the District’s reasonable opinion, the Casualty renders, for more than 180 days, the entire Premises inaccessible or 33% or more thereof unusable for the normal conduct of the District’s operations then conducted on the Premises, (ii) Landlord and the District each shall have the right to terminate this Lease on sixty (60) days’ prior written notice given within 30 days of the date of the Casualty if, in Landlord’s reasonable judgment, the repair and restoration cannot be completed within 180 days after the date of the Casualty (which time period includes the time needed for effecting a satisfactory settlement with any insurance company involved, removal of debris, preparation of plans and issuance of all required governmental permits), and (iii) Landlord and the District shall each have the right to terminate this Lease on 30 days’ prior written notice given within 30 days of the date of the Casualty if there is then left in the Lease Term less

than twelve (12) calendar months. If the Premises or any part thereof shall be damaged or destroyed, the District shall provide prompt notice thereof to Landlord.

(b) Landlord’s obligations to repair and restore the Building and the Premises as set forth in Section 16.1(a) are subject to the following conditions precedent having been satisfied, in Landlord’s reasonable judgment. If any of the following conditions have not been so satisfied, Landlord shall notify the District of the same, and each Party shall have the right to terminate this Lease after 30 days prior written notice:

(i)Landlord and the District each shall not have exercised its right to terminate this Lease to the extent permitted to do so pursuant to Section 16.1(a);

(ii)Landlord shall likely be able to obtain, or shall have obtained, all necessary governmental or quasi-government approvals and similar authorizations to rebuild the Building as required herein, including, but not limited to, zoning approvals and permits; and

(iii)Adequate insurance proceeds shall be available for the repair and restoration, and Landlord’s mortgagee, if any, shall have permitted the insurance proceeds to be used to repair and restore the Building; or Landlord shall have an alternative source to provide for such funds.

16.2If this Lease is terminated pursuant to Section 16.1, then Annual Rental and any Additional Rent shall be apportioned (based on the portion of the Premises that is usable after the Casualty) and paid to the date of termination. If this

Lease is not terminated as a result of the Casualty, then until such repair and restoration of the Premises are substantially complete, the District shall be required to pay Annual Rental and any Additional Rent only for the portion of the Premises that is usable while such repair and restoration are being made.

16.3Intentionally Deleted.

16.4 In addition to the District’s rights set forth in this Section 16, if a Casualty is not caused by District Negligence and continues for 10 consecutive days, and Landlord has failed to commence and thereafter diligently pursue efforts to repair the Casualty within such time period, then one (1) Business Day following the delivery of written notice by the District to Landlord, the District may, but shall not have the obligation to, implement such reasonable steps as may be required in order to repair the Casualty at Landlord’s sole cost and expense. Landlord shall reimburse the District within 10 Business Days following written demand by the District thereof (such demand to include copies of invoices and a certification that such costs were actually incurred by the District) for any reasonable third party costs incurred by the District in repairing the Casualty. Landlord shall be deemed to have consented to the District performing any alterations or replacements that are necessary in order to eliminate such Casualty, provided that the District shall notify Landlord thereof in writing and reasonably cooperate with Landlord to reasonably include Landlord or its Agents in planning and implementing such alterations or replacements.

17.CONDEMNATION

17.1If 25% or more of the Premises, or the use or occupancy thereof, shall be taken or condemned by any governmental or quasi‑governmental authority (other than in each case the District of Columbia) for any public or quasi‑public use or purpose or sold under threat of such a taking or condemnation (collectively, “Condemned”), then this Lease shall terminate on the day prior to the date title thereto vests in such authority and Annual Rental and any Additional Rent shall be apportioned as of such date. If less than 25% of the Premises or the use or occupancy thereof is Condemned, then the District shall have the right to terminate this Lease upon written notice to Landlord. If the District does not elect to terminate this Lease, then this Lease shall continue in full force and effect as to the part of the Premises not so Condemned, except that, as of the date title vests in such authority, the District shall not be required to pay Annual Rental or any Additional Rent with respect to the part of the Premises so Condemned. Notwithstanding anything herein to the contrary, if 25% or more of the Land or the Building is Condemned, then whether or not any portion of the Premises is Condemned, Landlord and the District each shall have the right to terminate this Lease by giving at least 60 days’ prior notice of such termination at any time after such condemnation. This Lease shall terminate on the date specified in the notice and Annual Rental and Additional Rent shall be adjusted to such date.

17.2Landlord reserves all rights to any award paid because of any taking of the Premises. The District assigns to Landlord any right the District may have to such award. Further, the

District shall make no claims against Landlord or the condemning authority for damages. Notwithstanding the foregoing, the District may claim and recover from Landlord or the condemning authority (so long as that is not the District of Columbia), as applicable, a separate award for the District’s moving expenses, business dislocation damages, the District’s personal property and fixtures, or the unamortized costs of leasehold improvements paid for by the District (excluding any leasehold improvements paid for through the use of an allowance from Landlord) but only to the extent that (x) such amounts are awarded to the District in a separate proceeding, and (y) Landlord’s award is not thereby reduced. Each Party shall seek its own award, as limited above, at its own expense. Notwithstanding the provisions of Section 17.1, if a leasehold estate is necessary for the District to obtain an award as set forth above, then this Lease shall not be deemed to terminate pursuant to its terms or by a Party’s election as set forth in Section 17.1 until such time as the proceeding to obtain any such award is concluded; provided, however, in such event the obligations of the District (including any financial obligations under this Lease, including without limitation Annual Rental and Additional Rent), excluding any rental obligation that has already accrued but is not yet due and payable, shall terminate if this Lease would otherwise be deemed to have terminated pursuant to its terms or by a Party’s election as set forth in Section 17.1.

18.DEFAULT

18.1 District Default.

(a)It shall be a default of the

EXECUTION VERSION

District (“District Default”) hereunder if the District fails to: (i) pay Annual Rental or Additional Rent on the date due and such failure shall remain uncured for a period of 30 calendar days after Landlord notifies the District in writing of such failure (subject to Landlord’s obligation to deliver documents and information pursuant to Section 7.3 hereof required for the District to process payments to Landlord); (ii) perform or observe any non-monetary obligation of the District under this Lease (but not including any failure to perform or observe such obligation that constitutes a District Delay) within the period provided herein for such performance, and if no express period for performance is provided, then within 30 days, and if such failure shall remain uncured for such period after Landlord notifies the District in writing of such failure, which written notice shall set forth in reasonable detail the nature and extent of the failure and identifying the applicable Lease provision requiring such obligation to be performed, or within such longer period of time as may be necessary for such cure so long as the District shall promptly commence and thereafter diligently pursue the curing thereof but no later than 120 days from the date of such notice; (iii) any sublease or assignment not permitted by Section 21 shall occur; or (iv) the District abandons the Premises. It is specifically understood and agreed that any failure to take any action that might be deemed to violate the Anti-D eficiency Acts or any failure to obtain a certification of the availability of appropriated funds in accordance with Section 2 6.1 shall not constitute a District Default; provided that the foregoing shall not prevent Landlord from pursuing any remedies against the District as a result of District Negligence or a breach of this Lease by

the District.

(b)Upon the occurrence of a District Default, Landlord, in its sole discretion, may seek: (i) in the case of a monetary District Default, all remedies available to it under the Quick Payment Act, D.C. Code § 2-221.01, et seq., as may be amended from time to time, and otherwise at law or equity; or (ii) in the case of any other District Default, all remedies available at law or equity. In accordance with Section 26.1, any deficiency in Annual Rental or any financial obligation of the District shall not exceed the amount of appropriated funds actually available at the time of the occurrence of a District Default. Notwithstanding anything to the contrary herein, Landlord agrees to use commercially reasonable efforts to relet the Premises and mitigate damages following the surrender of, or Landlord’s recovery of, possession of the Premises.

(c) In the event of a District Default pursuant to Section 18.1(a)(ii), and after the expiration of the applicable notice and cure period provided for therein, upon an additional 15 Business Days’ prior written notice to the District (during which time the District shall have a further opportunity to cure such District Default), Landlord may, but shall not be required to, effect such cure (subject in all events to Section 15.1 hereof), unless the District notifies Landlord that it has already engaged a provider of goods and/or services to effectuate the cure of such District Default. The taking of such action by Landlord shall not prevent Landlord from pursuing any remedy it is otherwise entitled to in connection with such District Default in accordance with Section 18.1(b); provided, however, that if Landlord cures such District Default as set forth in this Section 18.1(c), any such

PAGE 42 OF 135(as modified) DC DGS FORM L-105 (3/2018)

EXECUTION VERSION

default shall be deemed to be cured (provided further that Landlord may include the cost of such cure within the calculation of actual damages which Landlord may seek at law or in equity in connection with the curing of such District Default).

(d)If Landlord shall institute proceedings against the District and a compromise or settlement thereof shall be made, then the same shall not constitute a waiver of the same or of any other covenant, condition or agreement set forth herein, nor of any of Landlord’s rights hereunder unless expressly agreed by Landlord and the District. Neither the payment by the District of a lesser amount than the monthly installment of Annual Rental due hereunder (or any other financial obligation), nor any endorsement or statement on any check or letter accompanying a check for payment of rent or other sums payable hereunder shall be deemed an accord and satisfaction. Landlord may accept the same without prejudice to Landlord’s right to recover the balance of such rent or other sums or to pursue any other remedy. Notwithstanding any request or designation by the District, Landlord may apply any payment received from the District to any payment then due under the Lease.

18.2 Landlord Default.

(a)It shall be a Landlord default (“Landlord Default”) hereunder if Landlord fails to perform or observe any of its obligations under this Lease (but not including any failure to perform or observe such obligation that constitutes a Landlord Delay) within the period provided for such performance (including any notice and cure period, if applicable), and if no express period for

notice and cure is provided, then after a period of 30 days from the date Landlord receives written notice thereof from the District setting forth in reasonable detail the nature and extent of the failure and identifying the applicable Lease provision requiring such obligation to be performed; provided, however, that Landlord shall not have committed a Landlord Default if such failure is of a type and nature that cannot reasonably be cured within such thirty (30) day period, so long as Landlord promptly commences the curing of such failure within such thirty (30) day period and thereafter diligently pursues the curing of such failure but no later than 120 days from the date of the notice.

(b) Upon the occurrence of a Landlord Default, the District may pursue any other remedies available to it at law or equity. In addition to the foregoing, or in lieu thereof, upon the occurrence of a Landlord Default, upon one (1) Business Day following the delivery of written notice by the District to Landlord, the District may, but shall not have the obligation to, implement such reasonable steps as may be required in order to cure such Landlord Default at Landlord’s sole cost and expense. Landlord shall reimburse the District within 10 Business Days following written demand by the District thereof (such demand to include copies of invoices and a certification that such costs were actually incurred by the District), of any reasonable third party costs incurred by the District in curing such Landlord Default. Landlord shall be deemed to have consented to the District performing any alterations, replacements or work that is/are necessary in order to eliminate such Landlord Default, provided that the District shall notify Landlord thereof in writing and reasonably cooperate with Landlord to

EXECUTION VERSION

r easonably include Landlord in planning and implementing such alterations, replacements or work.(c)T he availability of insurance proceeds under Section 14 shall not be interpreted to deprive the District of its right to be awarded specific performance or an injunction in an action brought to enforce any of its rights under this Lease. Furthermore, nothing in Section 14 shall be interpreted as limiting any remedy the District may have pursuant to the False Claims Act, as the District is not authorized to limit such authority or remedy.

19.SUBORDINATION

19.1This Lease shall be subject and subordinate to the lien, provisions, operation and effect of all mortgages, deeds of trust, ground leases or other security instruments that may encumber the Building or the Land, or both (each, a “Mortgage”, and collectively, “Mortgages”) of record after the Lease Commencement Date, to all funds and indebtedness intended to be secured thereby, and to all renewals, extensions, modifications, recastings or refinancings thereof, provided that Landlord shall, at no cost or expense to the District, (i) execute, and shall cause the applicable mortgagee or lien holder to execute, and deliver to the District a subordination, non-disturbance, and attornment agreement in the form of, and substantially in the substance of, “Exhibit F” attached hereto and made a part hereof (an “SNDA”); and (ii) cause Ground Lessor to execute and deliver to the District a sublease recognition agreement in the form of, and substantially in the substance of, “Exhibit L” attached hereto and made a part hereof (a “Recognition Agreement”). If Landlord and the

applicable mortgagee, lien holder, or ground lessor do not execute and deliver to the District such an SNDA or Recognition Agreement in the form of, and substantially in the substance of, “Exhibit F” or “Exhibit L”, respectively, this Lease shall not be subordinate to any such Mortgage unless and until Landlord delivers such an SNDA or Recognition Agreement to the District. Such SNDA or Recognition Agreement shall be in recordable form and may be recorded at the election of any Party, mortgagee or ground lessor (at no cost or expense to the District unless the District elects to record the same).

19.2Landlord agrees that within 60 days of (x) the Lease Commencement Date, or (y) such later date on which Landlord executes a Mortgage encumbering its Ground Lease interest, Landlord shall provide to the District, at no cost to the District, an SNDA in favor of the District from Landlord and each mortgage holder or lien holder of record (each, a “Mortgagee”), in the form of, and substantially in the substance of, “Exhibit F” attached hereto and made a part hereof. Until such time as an SNDA signed by Landlord and any applicable Mortgagee is delivered to the District by Landlord, this Lease shall not be subordinate to any such Mortgage then in existence unless and until Landlord delivers such an SNDA to the District. In the event Landlord does not provide the District with an SNDA within 60 days of the date set forth in clause (x) or (y) above, the District shall have the right to terminate this Lease, effective immediately upon the District giving written notice of termination to Landlord. Such SNDA shall be in recordable form and may be recorded at the election of any

reasonable inquiry to appropriate District of Columbia officials; and (g) that the Certificate shall not be deemed to be a representation or warranty by the District that the Premises comply with any Laws or of the condition of, or the absence of, any defects in the Premises (or any portion thereof).

21.ASSIGNMENT AND SUBLETTING

21.1The District shall not assign this Lease (or all or any of the District’s rights hereunder or interest herein), or sublet the Premises or any part thereof, without obtaining the prior written consent of Landlord, which consent Landlord may withhold in its sole discretion with respect to an assignment, but which consent Landlord shall not unreasonably withhold, condition or delay with respect to a sublet. The District shall not encumber this Lease without obtaining Landlord’s prior written consent, which consent Landlord may withhold in its sole discretion. Notwithstanding anything in this Lease to the contrary, the Parties hereby agree that the District’s (i) substitution of another agency or instrumentality of the District of Columbia to use the Premises in accordance with Section 3.1 above, (ii) allowing community groups or other entities to use the first floor conference room (either free of charge or with a fee), or (iii) licensing of a portion of the Premises to telecommunications providers to install in-building distributed cellular antenna systems for improved service in the Building (either free or charge or with a fee), shall not constitute an assignment or subletting under this Lease and shall not require the consent of Landlord. In the event that Landlord, exercising good faith in all respects, fails or refuses to respond to any request by the

If Landlord consents or is deemed to have consented to the District’s assignment of this L ease, then the District shall be released from any and all obligations and liabilities with respect to this Lease, or arising under this Lease, of any nature whatsoever, except for any such obligations or liabilities that arise and accrue prior to the date of the permitted assignment of this Lease by the District.

21.3All restrictions and obligations imposed pursuant to this Lease on the District shall be deemed to extend to any subtenant, assignee, licensee, or transferee (each an “Assignee”). Any Assignee shall be deemed to have assumed obligations as if such A ssignee had originally executed this Lease, and, at Landlord’s request, shall execute promptly a document confirming such assumption. Each sublease shall be subject to the condition

that, if the Lease Term is terminated or Landlord succeeds to the District’s interest in the Premises by voluntary surrender or otherwise, at Landlord’s option, the subtenant shall be bound to Landlord for the balance of the term of such sublease and shall attorn to and recognize Landlord as its landlord under the then existing terms of such sublease.

22.HOLDING OVER

If the District does not immediately surrender the Premises or any portion thereof upon the expiration of the then applicable Lease Term, or earlier termination date (as expressly provided in this Lease), as applicable, then subject in all events to the Anti-Deficiency Acts, applicable Laws, appropriate authorization from the District, and the certification of the availability of appropriated funds for such purpose, the Net Rental payable by the District hereunder shall be increased to one hundred twenty-five percent (125%) of the Net Rental payable by the District during the month immediately preceding such holdover, for the period of the first nine (9) months after such expiration or termination. Notwithstanding the foregoing, the District shall continue to pay all Operating Costs, Real Estate Taxes and Parking Fees that were in effect during the last month of the Lease Term, as adjusted pursuant to Section 7 hereof. If the holdover shall continue after such nine (9) month holdover period, then the amount of the increase in Net Rental shall be increased to 150%

Notwithstanding any other provision of this Lease, Landlord’s right to recover damages arising from a holdover period shall be limited to the right to (i) collect the increased Net Rental provided above; or (ii) evict the District. U nder no circumstances shall the District be liable to Landlord for any other damages whatsoever arising directly or indirectly from the holdover period.

Notwithstanding any other provision of this Lease, Landlord’s acceptance of Annual Rental during any holdover period shall not in any manner adversely affect Landlord’s other rights and remedies under this Lease. The District’s obligations during any such holdover period shall remain subject to the Anti-Deficiency Acts and applicable Laws.

(f)Contracts. Landlord shall insert the foregoing nondiscrimination in employment provisions in all contracts for procurement of goods and services relating to the performance of Landlord’s obligations hereunder, except contracts for standard commercial supplies or raw materials, unless exempted by rules, regulations or orders of the District, so that such provisions will be binding upon each contractor or vendor. Landlord shall take such action with respect to any contractor or vendor as the District may direct as a means of enforcing such provisions, including without limitation sanctions for noncompliance; provided,

however, that in the event Landlord becomes involved in or is threatened with litigation with a contractor or vendor as a result of such direction by the District, Landlord shall give notice thereof to the District and Landlord may request that the District enter into such litigation to protect the interests of the District.

(a)Landlord shall, at Landlord’s sole cost and expense, be responsible for designing and constructing the Base Building, and performing, in a first class, good and workmanlike manner, and in accordance with the terms of this Work Exhibit, the Base Building Work. The “Base Building Work” shall mean Landlord’s design, construction and completion of a building with RSF sufficient to include the Premises and pursuant to the Base Building Plans and Requirements (such completed building being the “Base Building”).

by the District pursuant to the foregoing shall be accompanied by a detailed explanation therefor. If the District does not timely approve or disapprove the Schematic Plans, it shall be deemed to have approved the same. If the District disapproves the Schematic Plans, it shall approve or disapprove any resubmission thereof within seven (7) Business Days after receipt thereof pursuant to the same standard described above. Landlord shall cause the exterior street façade of the Building to look substantially similar to the exemplar exterior elevation drawing forth in “Schedule 3” attached hereto and made a part hereof (the “Exterior Elevation Drawing”). The remainder of the Building elevations shall be designed by the Base Building Project Architect and reviewed by the District (which may provide comments that Landlord may consider). The Base Building, and th e performance of the Base Building Work, shall be in compliance with all existing applicable Laws. Landlord shall submit to the District design stage and construction stage plans for the Base Building for the review and approval of the District as set forth below. The District shall have a right to notify Landlord that it disapproves any such plans only to the extent the plans: (i) will have a material adverse effect on the District’s plans for the Tenant Improvements as set forth in the District Requirements (defined in Section 4 below); (ii) are materially inconsistent with the Schematic Plans; or (iii) are materially inconsistent with the Exterior Elevation Drawing. Any such disapproval must be delivered by the District to Landlord no later than seven (7) Business Days after receipt thereof. If the District does not timely deliver a disapproval which identifies in detail the reason for such disapproval, the District shall be deemed to have approved such plans. If the District timely delivers a disapproval notice with the details required herein, Landlord shall work with the District to address the District’s concerns and, if applicable, shall revise the plans and resubmit the same to the District, and the District shall have another opportunity to disapprove the same pursuant to the provisions of this paragraph. In no event shall the District have any right to deliver a notice of disapproval to Landlord with respect to any set of plans for a design phase which do not reflect a material change from the plans for the design phase previously submitted the District (it being agreed that additional detail provided in subsequent plans shall not constitute a change).

(c)Landlord shall, at its sole cost and expense, cause the Building to be designed and constructed to achieve, at minimum, the Leadership in Energy and Environmental Design (LEED) Silver rating for Core and Shell. Landlord shall register such design and construction project, and apply for certification, with the U.S. Green Building Council (USGBC) for LEED. Landlord shall pay all fees associated with registering, applying for, appealing, and otherwise obtaining LEED certification(s). The project shall be listed as “non-confidential”.

(d)Landlord, at its sole cost and expense, shall furnish all labor and materials to construct, furnish and complete all of the work necessary to finish and ready the Base Building for further improvement by the Tenant Improvements, and otherwise make the Base Building suitable for use and occupancy by the District in accordance with Laws, subject to completion of the Tenant Improvements.

Form of SNDA

Subordination, Non-Disturbance and

Attornment Agreement

THIS SUBORDINATION, NONDISTURBANCE AND ATTORNMENT AGREEMENT (this “Agreement”) is made and entered into as of _________________, ___, 20__ (the “Effective Date”), by and between ______________________, a(n) _______________ ______________ (“Landlord”), _________________________, a(n) ___________________ __________________, which has executed this Agreement as Landlord’s lender (together with its successors and assigns, “Lender”), and the District of Columbia, a municipal corporation, acting by and through its Department of General Services (the “District”). Landlord, Lender and the District are each referred to herein as a “Party” and collectively as the “Parties”.

W I T N E S S E T H:

WHEREAS, Lender intends to fund a commercial mortgage loan (the “Loan”) to Landlord, which loan will be secured by either a mortgage or a deed of trust, among other instruments (each and collectively, the “Mortgage”) on the Property described on “Schedule 1”, together with present or future improvements (the “Property”);

WHEREAS, Landlord has demised to the District a leasehold interest under that certain In-Lease Agreement, by and between ______________ and the District, with a Lease Commencement Date (as defined therein) of ________________ (together with all amendments, options, extensions, and renewals thereof, being hereinafter the “Lease” ”; any capitalized term used but not defined herein shall have the meaning given to such term in the Lease);

WHEREAS, as a condition of the Loan’s funding, Landlord has assigned or will assign its interest in the Lease to Lender as part of Lender’s security for the Loan; and

WHEREAS, the District agrees to enter into this Agreement in order to benefit from the promises by Lender that are set forth in this Agreement.

NOW, THEREFORE, in consideration of the foregoing and for good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

1.Subordination. In accordance with Section 19 of the Lease, the District acknowledges that the Lease is subordinate to the lien of the Mortgage on the Property. Lender hereby acknowledges and agrees that such subordination shall not operate in any way whatsoever to adversely affect any right of the District under the Lease.

PAGE 103 OF 135(as modified) DC DGS FORM L-105 (3/2018)

3924 Minnesota Avenue NE

EXECUTION VERSION

2.Attornment. If Lender forecloses the Mortgage or acquires title to the Property by deed-in-lieu of foreclosure, or in any other manner succeeds to the interest of Landlord under the Lease, or if Lender shall otherwise take possession of the P roperty, then upon receipt of written notice from Lender, the District shall attorn to Lender as its landlord under all of the terms, covenants and conditions of the Lease for the balance of the term thereof remaining (and of any extensions thereof that may be effected in accordance with any option therefor), as set forth in the Lease, with t he same force and effect as if Lender were Landlord under the Lease. Such attornment shall be effective and self-operative immediately upon receipt of written notice from Lender that Lender has succeeded to the interest of Landlord, whereupon the District shall recognize Lender, or any perso n claiming by through or under Lender, as the landlord under the Lease without the execution of any further instruments on the part of any of the Parties. Provided no default by the District has occurred and is continuing, which default under the terms of the Lease would give Landlord (or Lender as successor in interest to Landlord) the right to terminate the Lease, the Lease shall at all times continue in full force and effect, and the respective rights and obligations of the District and Lender upon such attornment shall be governed by the Lease. If Lender requests, the District agrees to execute, acknowledge, and deliver to Lender any certificate or other instrument that Lender reasonably requests (in the District’s determination) to confirm such attornment at no cost or expense to the District. If the District requests, Lender covenants and agrees to execute a novation agreement in the form reasonably acceptable to the District that requests that the District recognize a name change or a successor in interest to the Lease. In connection with any attornment pertaining to an asset transfer, at the District’s request, Lender shall deliver to the District, as applicable, each of the following:

a.A document describing the proposed transaction giving rise to such transfer;

b.the effective date of the transfer;

c.an authenticated copy of the instrument effecting the transfer (including without limitation a bill of sale, certificate of merger, contract, deed, or court decree);

d.an authenticated copy of the transferee’s certificate and articles of incorporation if an entity was formed to receive the transferor’s assets (however, if the entity was formed for a purpose other than to receive the transferor’s assets, include a statement to that effect); and

e.a certified copy of applicable entity authorizing resolutions (for both the transferee and the transferor) authorizing such transfer of assets.

3.Non-Disturbance. So long as no default by the District has occurred and is continuing, which default under the terms of the Lease would give Landlord (or Lender as successor in interest to Landlord) the right to terminate the Lease, Lender shall not disturb the District’s quiet enjoyment, possession or use of the Premises and the Property, as applicable under the Lease.

9.Severability. Each provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

10.No Partnership; No Third Party Beneficiaries. Nothing contained in this Agreement shall be deemed or construed to create a partnership or joint venture of, between, or amongst the Parties, or to create any other relationship between the Parties hereto other than those contemplated herein. Nothing contained in this Agreement shall be deemed or construed to create any third party beneficiaries.

District of Columbia laws and regulations applicable to Landlord and shall remain so for the term of the Lease.

13.Anti-Deficiency Limitations.

(a)Whether expressly or impliedly qualified or limited in any Section of the Lease, the obligations of the District to fulfill any financial obligation pursuant to the Lease or any subsequent agreement entered into pursuant to the Lease to which the District is a party (an “Other Agreement”; and together with the Lease, any “Applicable Agreement”), or referenced in any Applicable Agreement, are and shall remain subject to the provisions of (a) the federal Anti-Deficiency Act, 31 U.S.C. §§ 1341-1351 and 1511-1519 (2004), and D.C. Official Code §§ 1-206.03(e) and 47-105 (2012 Repl.); (b) the District of Columbia Anti-Deficiency Act, D.C. Official Code §§ 47-355.01 et seq. (2012 Repl. and 2014 Supp.) ((a) and (b) collectively, the “Anti-Deficiency Acts”); and (c) § 446 of the District of Columbia Home Rule Act, D.C. Official Code § 1-204.46 (2012 Repl.), as each may be amended from time to time and each to the extent applicable to any Applicable Agreement. Pursuant to the Anti-Deficiency Acts, nothing in the Lease shall create an obligation of the District in anticipation of an appropriation by the United States Congress (“Congress”) for such purpose, and the District’s legal liability for the payment of any financial obligation, including but not limited to any Annual Rental or Additional Rent, under any Applicable Agreement shall not arise or obtain in advance of the lawful availability of appropriated funds for the applicable fiscal year as approved by Congress and the District of Columbia (references in this Section to “District of Columbia” shall mean the District of Columbia as a sovereign entity, and not as a tenant under the Lease).

Landlord confirms that it has read and familiarized itself with the Anti-Deficiency Acts and has full knowledge of such laws and the impact on the District’s financial obligations hereunder.

(b)If no appropriation is made by the District of Columbia or Congress to pay any financial obligation, including, but not limited to any Annual Rental or Additional Rent, under any Applicable Agreement for any period after the District of Columbia fiscal year for which appropriations have been made, and in the event appropriated funds for such purposes are not otherwise lawfully available, the District shall not be liable to make any

payment under such Applicable Agreement upon the expiration of any then-existing appropriation.

10.Anti-Deficiency Limitations.

| (a) | Whether expressly or impliedly qualified or limited in any Section of the Lease, the obligations of the District to fulfill any financial obligation pursuant to the Lease or any subsequent agreement entered into pursuant to the Lease to which the District is a party (an “Other Agreement”; and together with the Lease, any “Applicable Agreement”), or referenced in any Applicable Agreement, are and shall remain subject to the provisions of (a) the federal Anti-Deficiency Act, 31 U.S.C. §§ 1341-1351 and 1511-1519 (2004), and D.C. Official Code §§ 1-206.03(e) and 47-105 (2012 Repl.); (b) the District of Columbia Anti-Deficiency Act, D.C. Official Code §§ 47-355.01 et seq. (2012 Repl. and 2014 Supp.) ((a) and (b) collectively, the “Anti-Deficiency Acts”); and (c) § 446 of the District of Columbia Home Rule Act, D.C. Official Code § 1-204.46 (2012 Repl.), as each may be amended from time to time and each to the extent applicable to any Applicable Agreement. Pursuant to the Anti-Deficiency Acts, nothing in the Lease shall create an obligation of the District in anticipation of an appropriation by the United States Congress (“Congress”) for such purpose, and the District’s legal liability for the payment of any financial obligation, including but not limited to any rent under any Applicable Agreement shall not arise or obtain in advance of the lawful availability of appropriated funds for the applicable fiscal year as approved by Congress and the District of Columbia (references in this Section to “District of Columbia” shall mean the District of Columbia as a sovereign entity, and not as a subtenant under the Lease). During the term of the Lease, the District of Columbia agency authorized and delegated by the Mayor of the District of Columbia to administer the Lease shall, for each corresponding District of Columbia fiscal period, include in the then-current services funding level package a request sufficient to fund the District’s known financial obligations under the Lease for such fiscal period. Fee Owner and Landlord each confirm that it has read and familiarized itself with the Anti-Deficiency Acts and has full knowledge of such laws and the impact on the District’s financial obligations hereunder.
