4 shall pay to Landlord: (i) the monthly Fixed Rent for the first full calendar month of the Term after the Abatement Period; and (ii) cash in the amount of the Security Deposit. Within sixty (60) days after the execution of this Lease, Tenant shall deliver to Landlord the LOC (as defined below) to replace the cash Security Deposit, and within two (2) business days after Tenant’s delivery of the LOC to Landlord, Landlord shall wire the cash Security Deposit back to Tenant per Xxxxxx’s wiring instructions. No interest shall be paid to Tenant on the Security Deposit, and Landlord shall have the right to commingle the Security Deposit with other funds of Landlord. If Tenant commits an Event of Default (as defined in Section 17), Landlord may use, apply or retain the whole or any part of the Security Deposit to the extent necessary for the payment of: (A) any rent or other sums that Tenant has not paid when due; (B) any sum expended by Landlord in accordance with the provisions of this Lease which is Xxxxxx’s responsibility to pay; and/or (C) any sum that Landlord expends or is required to expend in connection with such Event of Default. Xxxxxxxx’s use of the Security Deposit shall not prevent Landlord from exercising any other remedy available to Landlord under this Lease, at law or in equity and shall not operate as either liquidated damages or as a limitation on any recovery to which Landlord may otherwise be entitled. If any portion of the Security Deposit is used, applied, or retained by Landlord, Tenant shall, within 10 days after written demand therefor, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount, and if Tenant fails to do so an Event of Default shall be deemed to have occurred. Landlord shall return the Security Deposit or the balance thereof (as applicable) to Tenant within one (1) month after the latest of the Expiration Date, Xxxxxx’s surrender of possession of the Premises to Landlord in the condition required under this Lease, Xxxxxx’s payment of all outstanding Rent, and Xxxxxxxx’s receipt of written notice from Tenant of its forwarding address. Upon the return of the Security Deposit or the balance thereof (as applicable) to Tenant, Landlord shall be completely relieved of liability with respect to the Security Deposit. If the originally named Xxxxxx has assigned this Lease, Landlord may return the Security Deposit or the balance thereof (as applicable) to the current Tenant unless Landlord receives reasonably satisfactory evidence of the originally named Xxxxxx’s right to receive the Security Deposit. If Landlord conveys ownership of the Building, Landlord shall deliver the Security Deposit to the transferee, and Landlord shall thereupon be released from all liability for the return of such Security Deposit and Tenant shall look solely to the transferee for the return of the Security Deposit. (c) If Landlord does not receive the full payment from Tenant of any Rent when due under this Lease (without regard to any notice and/or cure period to which Tenant might be entitled), Tenant shall also pay to Landlord as Additional Rent a late fee in the amount of 5% of such overdue amount. Notwithstanding the foregoing, upon Xxxxxx’s written request, Landlord shall waive the above-referenced late fee 2 times during any 12 consecutive months of the Term provided Tenant makes the required payment within 3 business days after receipt of notice of such late payment. With respect to any Rent payment (whether it be by check, ACH/wire, or other method) that is returned unpaid for any reason, Landlord shall have the right to assess a fee to Tenant as Additional Rent, which fee is currently $40.00 per returned payment. (d) As a condition precedent to the effectiveness of this Lease and as a guaranty of the prompt and complete performance by Tenant of each and every provision of this Lease and all obligations of Tenant hereunder, monetary and nonmonetary, Tenant shall deliver to Landlord, contemporaneously with its execution and delivery of this Lease, an irrevocable, automatically renewing, clean, and unconditional standby letter of credit issued by LOC Bank (as defined below) in the face amount of $108,206.34 (“LOC Amount”), which shall be substantially in the form attached as Exhibit G or otherwise in form acceptable to Landlord (“LOC”). The LOC shall be, among other things, subject to the International Standby Practices 1998, International Chamber of Commerce Publication No. 590, and irrevocable and unconditional, conditioned for payment solely upon presentation of the LOC and a sight draft. The LOC shall provide, inter alia, as follows: (i) the LOC shall be automatically renewing for the duration of the Term plus the subsequent 2 months with a minimum of 2 months’ prior written notice from LOC Bank to Landlord to exercise an early termination right by LOC Bank; (ii) the LOC shall be fully transferrable one

5 or more times to any successor or assignee of Landlord at no cost to Landlord and no cost to any such successor or assignee of Landlord; (iii) any draw or transfer of the LOC shall be permitted by facsimile or nationally recognized courier service to LOC Bank and shall not require a representative of Landlord to be present at such presentation or delivery to LOC Bank; (iv) any draws or transfers of the LOC shall only require signature by an authorized representative of Landlord; and (v) in no event shall any draw or transfer demand require a signature authentication of Landlord’s signatory by Xxxxxxxx’s bank or any other authenticating organization. Notwithstanding the foregoing requirements with respect to the LOC, any fee required to be paid in connection with any transfer of the LOC by Landlord to any successor or assignee shall be paid by Tenant within 30 days after receipt of invoice from Landlord. The LOC is not a security deposit and is in lieu of a guaranty. Tenant acknowledges and agrees that the LOC shall constitute an independent contract between the LOC Bank and Landlord, and the proceeds of any draws by Landlord under the LOC shall not constitute property of Tenant as debtor in any bankruptcy proceeding. The proceeds of the LOC shall be held or applied by Landlord in its sole discretion, and the receipt by Landlord of proceeds of the LOC under one or more draws hereunder shall not relieve Tenant of any obligations to make installment or other payments of Rent under this Lease, or otherwise discharge or release or relieve Tenant of compliance or performance of any terms and conditions under this Lease. If Landlord draws on the LOC, the proceeds may be used to compensate Landlord for its damages, including without limitation damages permitted under applicable Law, and Landlord shall have the right to hold any balance from the draw as part of the Security Deposit, in which event the Security Deposit shall be deemed increased by such amount. The delivery of the LOC and/or exercise by Landlord of its rights under such LOC shall not constitute liquidated damages or otherwise release, waive, or estop Landlord from asserting any and all claims, or exercising any and all rights and remedies Landlord has or may have with the passage of time under this Lease and applicable Law. The LOC shall expressly provide that Landlord (and/or its successors and assigns) is entitled to make one or more draws from time to time under the LOC, in whole or in part, and Landlord may use, apply, or retain the proceeds of the LOC upon the occurrence of any of the following: (A) Tenant has failed to comply with or perform under any of the terms and conditions of this Lease; (B) a petition has been filed by or against Tenant commencing a case under Title 11 of the United States Code or other state or federal bankruptcy or insolvency laws, as amended or reenacted with the passage of time; (C) Tenant has failed to provide a replacement LOC, in form and substance acceptable to Landlord, at least 30 days prior to the expiration of the existing LOC; or (D) Tenant has failed to cause the delivery to Landlord of an amendment to the LOC, in form and substance acceptable to Landlord, extending the LOC for the duration of the Term plus the subsequent 2 months. Tenant shall procure the issuance of a replacement or amended LOC in the LOC Amount concurrently with any assignment of this Lease by Xxxxxx, or the vesting of this Lease in Tenant as a reorganized debtor or other successor emerging from bankruptcy, so as to assure the continued ability of Landlord to draw under the LOC as contemplated herein. Notwithstanding anything to the contrary in this Lease, it shall be an automatic Event of Default if at any time during the Term there is no valid LOC. The use of the LOC by Landlord shall not prevent Landlord from exercising any other remedy provided by this Lease or by law and shall not operate as either liquidated damages or as a limitation on any recovery to which Landlord may otherwise be entitled. Landlord shall return the LOC to the issuer thereof within 60 days after the later of the Expiration Date, Xxxxxx’s surrender of possession of the Premises to Landlord in the condition required under this Lease, and Xxxxxx’s payment of all outstanding Rent. If the LOC is drawn on by Landlord, Tenant shall, within 10 days after the written demand therefor is made by Landlord, restore the LOC to the LOC Amount. If Landlord has reason to believe that the LOC Bank or any successor to such institution, including the FDIC, would not fully honor such LOC, Landlord may require Tenant to replace the LOC with a new LOC issued by a new LOC Bank within 5 business days after receipt of a written request from Landlord to replace the LOC. Tenant’s failure to do so timely shall, notwithstanding anything else in this Lease to the contrary, constitute an Event of Default for which there shall be no notice or grace or cure periods being applicable thereto other than such 5 business-day period. For purposes herein, the “LOC Bank” means a bank or financial institution: (a) the deposits of which are insured by the Federal Deposit Insurance Corporation; (b) whose long-term, unsecured and unsubordinated debt obligations are rated in the highest category by at least 2 of Fitch Ratings Ltd., Moody’s Investors

(v) “Taxes” means all taxes, assessments, and other governmental charges, whether general or special, ordinary or extraordinary, foreseen or unforeseen, including real estate taxes, sales taxes, and gross receipt taxes, that are levied or assessed against, or with respect to the ownership of, all or any portion of the Project during the Term or, if levied or assessed prior to the Term, are properly allocable to the Term, business property operating license charges, and real estate tax appeal expenditures incurred by Landlord. “Taxes” shall not include: (i) any inheritance, estate, succession, transfer, gift, franchise, corporation, net income or profit tax or capital levy that is or may be imposed upon Landlord; or (ii) any transfer tax or recording charge resulting from a transfer of the Building or the Project, or (iii) any penalties imposed on landlord for failure to timely pay Taxes; provided, however, if at any time during the Term the method of taxation prevailing at the commencement of the Term shall be altered such that in lieu of or as a substitute in whole or in part for any Taxes now levied, assessed, or imposed on real estate there shall be levied, assessed, or imposed: (A) a tax on the rents received from such real estate; or (B) a license fee measured by the rents receivable by Landlord from the Premises or any portion thereof; or (C) a tax or license fee imposed upon the Premises or any portion thereof, then the same shall be included in Taxes. Tenant may not file or participate in any Tax appeals for any tax lot in the Project. Further, “Taxes” shall not include any sales, use, use and occupancy, transaction privilege, or other excise tax that may at any time be levied or imposed upon Tenant, or measured by any amount payable by Tenant under this Lease (collectively, “Other Taxes”). Tenant shall pay all Other Taxes monthly or otherwise when due; if applicable Law requires Landlord to collect any Other Taxes, such Other Taxes shall be payable to Landlord as Additional Rent. (vi) “Tenant’s Share” means the rentable square footage of the Premises divided by the rentable square footage of the Building on the date of calculation, which on the date of this Lease is stipulated to be 9.56%. Tenant’s Share shall not increase during the Initial Term unless Tenant expands the Premises or leases additional space in the Building. (b) Commencing on September 1, 2025 (subject to Section 1(a)) and continuing thereafter during the Term, Tenant shall pay to Landlord in advance on a monthly basis on or before the first day of each month of the Term, payable pursuant to Section 5(c) below, Tenant’s Share of: (i) Project Electricity Costs to the extent Project Electricity Costs exceed Project Electricity Costs for the Base Year; (ii) Project Expenses to the extent Project Expenses exceed Project Expenses for the Base Year; and (iii) Taxes to the extent Taxes exceed Taxes for the Base Year. If the Building is operated as part of a complex of buildings or in conjunction with other buildings or parcels of land, then Landlord may prorate the common expenses and costs with respect to each such building or parcel of land in such manner as Landlord, in its sole but reasonable judgment, shall determine. Landlord shall calculate Operating Expenses using generally accepted accounting principles, and may allocate certain categories of Operating Expenses to the applicable tenants on a commercially reasonable basis, for example based on the type of use.

8 (c) For each calendar year (or portion thereof) for which Tenant has an obligation to pay any Operating Expenses, Landlord shall send to Tenant a statement of the monthly amount of projected Operating Expenses due from Tenant for such calendar year (“Estimated Operating Expenses”), and Tenant shall pay to Landlord such monthly amount of Estimated Operating Expenses as provided in Section 5(b), in advance on a monthly basis on or before the first day of each month of the Term without further notice or demand, until Xxxxxx’s receipt of the succeeding statement of Estimated Operating Expenses. As soon as administratively available (but in any event within 120 days after each calendar year or, at Landlord’s option, after a sale of the Project), Landlord shall send to Tenant a reconciliation statement of the actual Operating Expenses for the prior calendar year (“Reconciliation Statement”); provided, however, if Landlord does not provide such statements within such period, Landlord shall not have been deemed to waive its right to collect any amounts as Additional Rent unless Landlord fails to provide such statement within 18 months after the end of the applicable calendar year; provided, further, Landlord does not waive its right to deliver a corrected statement beyond such date should Landlord discover any errors. If the amount actually paid by Xxxxxx as Estimated Operating Expenses exceeds the amount due per the Reconciliation Statement, Tenant shall receive a credit in an amount equal to the overpayment, which credit shall be applied towards future Rent until fully credited. If the credit exceeds the aggregate future Rent owed by Xxxxxx, and there is no uncured default, Landlord shall pay the excess amount to Tenant within 30 days after delivery of the Reconciliation Statement. If Landlord has undercharged Tenant, then Landlord shall either send Tenant an invoice setting forth the additional amount due or indicate the amount due as part of the Reconciliation Statement, which amount shall be paid in full by Tenant within 30 days after receipt of such invoice. Tenant’s obligations under this Section shall survive the Expiration Date. (d) If, during the Term (including during the Base Year), less than 100% of the rentable area of the Building is or was occupied by tenants, Operating Expenses shall be deemed for such year to be an amount equal to the costs that would have been incurred had the occupancy of the Building been at least 100% throughout such year, as reasonably determined by Landlord and taking into account that certain expenses fluctuate with the Building’s occupancy level and certain expenses do not so fluctuate. In addition, if Landlord is not obligated or otherwise does not offer to furnish an item or a service to a particular tenant or portion of the Building (for example, if a tenant separately contracts with an office cleaning firm to clean such tenant’s premises) and the cost of such item or service would otherwise be included in Operating Expenses, Landlord shall equitably adjust Operating Expenses so the cost of the item or service is shared only by tenants actually receiving such item or service. All payment calculations under this Section shall be prorated for any partial calendar years during the Term and all calculations shall be based upon Operating Expenses as grossed-up in accordance with the terms of this Lease. If a category of expense is first included in Operating Expenses after the Base Year and such category of expense is not in substitution for a category of expense that was included during the Base Year, then for purposes of calculating Tenant’s liability for increases in Operating Expenses, Operating Expenses for the Base Year shall be increased to include the annualized cost of the new category of expense during the first year in which it was provided. (e) If Landlord or any affiliate of Landlord has elected to qualify as a real estate investment trust (“REIT”), any service required or permitted to be performed by Landlord pursuant to this Lease, the charge or cost of which may be treated as impermissible tenant service income under the laws governing a REIT, may be performed by an independent contractor of Landlord, Landlord’s property manager, or a taxable REIT subsidiary that is affiliated with either Landlord or Landlord’s property manager (each, a “Service Provider”). If Tenant is subject to a charge under this Lease for any such service, then at Landlord’s direction Tenant shall pay the charge for such service either to Landlord for further payment to the Service Provider or directly to the Service Provider and, in either case: (i) Landlord shall credit such payment against any charge for such service made by Landlord to Tenant under this Lease; and (ii) Tenant’s payment of the Service Provider shall not relieve Landlord from any obligation under this Lease concerning the provisions of such services.

10 pursuant to Section 5. “Project Utility Costs” means the total cost for all utilities serving the Project, excluding Project Electricity Costs and the costs of utilities that are directly metered or submetered to Building tenants or paid separately by such tenants. The cost of utilities payable by Tenant under this Section shall include all charges and surcharges, applicable taxes, and Landlord’s then-current charges for reading the applicable meters. Tenant shall pay such rates as Landlord may establish from time to time, which shall not be in excess of any applicable rates chargeable by Law, or in excess of the general service rate or other such rate that would apply to Tenant’s use if charged by the utility or municipality serving the Building or general area in which the Building is located. Tenant shall at all times comply with the rules, regulations, terms, policies, and conditions applicable to the service, equipment, wiring, and requirements of the utility supplying electricity to the Building. (b) For any separately metered utilities, Landlord is hereby authorized to request and obtain, on behalf of Tenant, Xxxxxx’s utility consumption data from the applicable utility provider for informational purposes and to enable Landlord to obtain full building Energy Star scoring for the Building. Landlord shall have the right, upon reasonable prior notice (which may be oral) to Tenant (except in the event of an emergency when no notice shall be required), to shut down the Building systems (including electricity and HVAC systems) for required maintenance, safety inspections, or any other commercially reasonable purpose, including without limitation in cases of emergency. Landlord shall not be liable for any interruption in providing any utility that Landlord is obligated to provide under this Lease, unless such interruption or delay: (i) renders the Premises or any material portion thereof untenantable for the normal conduct of Tenant’s business at the Premises, and Tenant has ceased using such untenantable portion, provided Tenant shall first endeavor to use any generator that serves the Premises or of which Tenant has the beneficial use; (ii) results from Landlord’s negligence or willful misconduct; and (iii) extends for a period longer than 5 consecutive days, in which case, Tenant’s obligation to pay Fixed Rent shall be abated with respect to the untenantable portion of the Premises that Tenant has ceased using for the period beginning on the 6th consecutive day after such conditions are met and ending on the earlier of: (A) the date Tenant recommences using the Premises or the applicable portion thereof; or (B) the date on which the service(s) is substantially restored. The rental abatement described above shall be Tenant’s sole remedy in the event of a utility interruption, and Tenant hereby waives any other rights against Landlord in connection therewith. Landlord shall have the right to change the utility providers to the Project at any time. In the event of a casualty or condemnation affecting the Building and/or the Premises, the terms of Sections 14 and 15, respectively, shall control over the provisions of this Section. (c) If Landlord reasonably determines that: (i) Tenant exceeds the design conditions for the heating, ventilation, and air conditioning (“HVAC”) system serving the Premises, introduces into the Premises equipment that overloads such system, or causes such system to not adequately perform its proper functions; or (ii) the heavy concentration of personnel, motors, machines, or equipment used in the Premises, including telephone and computer equipment, or any other condition in the Premises caused by Tenant (for example, more than one shift per day or 24-hour use of the Premises), adversely affects the temperature or humidity otherwise maintained by such system, then Landlord shall notify Tenant in writing and Tenant shall have 20 days to remedy the situation to Landlord’s reasonable satisfaction. If Tenant fails to timely remedy the situation to Landlord’s reasonable satisfaction, Landlord shall have the right to install one or more supplemental air conditioning units in the Premises with the cost thereof, including the cost of installation, operation and maintenance, being payable by Tenant to Landlord within 30 days after Xxxxxxxx’s written demand. Tenant shall not change or adjust any closed or sealed thermostat or other element of the HVAC system serving the Premises without Landlord’s express prior written consent. Landlord may install and operate meters or any other reasonable system for monitoring or estimating any services or utilities used by Tenant in excess of those required to be provided by Landlord (including a system for Landlord’s engineer reasonably to estimate any such excess usage). If such system indicates such excess services or utilities, Tenant shall pay Landlord’s reasonable charges for installing and operating such system and any supplementary air conditioning, ventilation, heat, electrical, or other systems or

Tenant is solely responsible for all costs associated with the installation, maintenance, and removal of the Roof Equipment. (ii) Tenant shall make a request for approval of the Roof Equipment by submission of specific plans and specifications for the work to be performed. Landlord shall respond in writing within 10 business days after receipt of the same, advising Tenant of approved contractors and those portions of the work that are acceptable and disapproving those portions of the work that are, in Landlord’s judgment, reasonably exercised, unacceptable and with respect to the plans, specifically detailing the nature of Landlord’s objection. Landlord shall have the right to separately meter the Roof Equipment for electricity or to cause Tenant to separately meter the Roof Equipment for electricity, in either case, at Tenant’s expense, and, in such case, Tenant shall pay as Additional Rent the electricity charges for the Roof Equipment directly to Landlord or to the electricity provider, as Landlord shall reasonably determine.

14 Conditions are fully satisfied, Tenant (but not any subtenant) shall have the nonexclusive right by written notice to Landlord within the first 6 months after the satisfaction of all of the Exterior Signage Conditions, at its sole cost and expense (including without limitation with respect to installation, maintenance, and removal), to place signage, based on Tenant’s Share, on one side of the exterior Building façade displaying Tenant’s corporate name and logo (“Exterior Signage”). “Exterior Signage Conditions” are that: (i) the originally named Tenant (and not a subtenant) or a Permitted Transferee is leasing and paying full Rent on 100% of the rentable area of the entire third floor of the Building, including, but not limited to, the original Premises; (ii) there has been no Event of Default; and (iii) this Lease is in full force and effect. The Exterior Signage shall be subject to Landlord’s approval in writing as to the placement, color, size, design, specifications, construction, and architectural compatibility of the Exterior Signage with the exterior of the Building and the Project. Landlord’s approval of the Exterior Signage shall create no responsibility or liability on the part of Landlord for the completeness, design, or sufficiency thereof, or the compliance of the Exterior Signage with the requirements of applicable Laws. On or prior to the Surrender Date (as defined in Section 18(a)), or within 10 days if any of the Exterior Signage Conditions are no longer true, Tenant shall remove the Exterior Signage, at Tenant’s sole cost and expense, and restore and repair all parts of the Building affected by the installation or removal of the Exterior Signage, to the condition existing prior to its installation or to a condition reasonably acceptable to Landlord (reasonable wear and tear and damage due to casualty or condemnation excepted). Landlord shall have the right to remove the Exterior Signage at Tenant’s expense if Tenant fails to comply with the preceding sentence. Tenant understands and agrees that it is solely responsible to ensure the upkeep and condition of the Exterior Signage to its original status, normal wear and tear and damage due to casualty or condemnation excepted. Specifically, any missing letters, whether by loss, destruction, wear, act of God, or otherwise, will be replaced at the full expense of Tenant and shall be repaired or replaced within 20 days after the occurrence of such deficiency. In addition to any other rights or remedies provided to Landlord in this Lease, if Tenant fails to complete such repair and/or replacement within such 20-day period, Landlord shall have the right, but not the obligation, to start to complete such repair and/or replacement at Tenant’s sole cost and expense, which sums shall constitute Additional Rent and be reimbursed by Tenant within ten days following demand therefor by Landlord. Prior to constructing or installing the Exterior Signage, Tenant shall have obtained and must continue to maintain all permits and/or approvals required by applicable Laws with respect to the construction, installation, and maintenance of the Exterior Signage, and shall have provided Landlord with sufficient evidence of the existence of such permits and/or approvals and that the construction and installation of the Exterior Signage will comply in all respects with all applicable Laws. Tenant shall be solely responsible for ensuring that the Exterior Signage is in compliance with all present and future applicable Laws. Tenant, at its sole cost and expense, shall insure the Exterior Signage as part of Tenant’s Property, and shall also carry liability insurance with respect to the Exterior Signage. Tenant shall protect, defend, indemnify, and hold harmless Landlord and all Landlord Indemnitees (as defined in Section 13(a)) from and against any and all claims, damages, judgments, suits, causes of action, losses, liabilities, penalties, fines, expenses, and costs (including, without limitation, sums paid in settlement of claims, and reasonable attorneys’ fees, consultant fees, and expert fees and court costs) arising out of or from or related to the construction, installation, maintenance, use, or removal of the Exterior Signage. (c) Subject to the Building rules and regulations, during the Term, Tenant shall have the nonexclusive right in common with others to use the Common Areas for their intended purposes. Not in limitation of the foregoing, Tenant has the nonexclusive right to use the parking facilities at the Project for parking standard-size automobiles of Tenant and its employees, with Tenant being entitled to unreserved parking at a ratio of no more than 3.2 per 1,000 square feet of rentable area of the Premises (rounded downward). All vehicles entering or parking in the parking areas shall do so at the owner’s sole risk and Landlord assumes no responsibility for any damage, destruction, vandalism, or theft with respect to such vehicles. There shall be no charge for parking during the Term. (d) Landlord shall have the right in its sole discretion to, from time to time, construct,

17 assign, transfer, hypothecate, mortgage, encumber, grant concessions or licenses, sublet, or otherwise dispose of all or any interest in this Lease or the Premises, or permit any person or entity other than Tenant to occupy any portion of the Premises (each of the foregoing is a “Transfer” to a “Transferee”), without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned, or delayed. Any Transfer undertaken without Landlord’s prior written consent (other than pursuant to Section 10(c) and 10(h)) shall constitute an Event of Default and shall, at Landlord’s option, be void and/or terminate this Lease. Subject to the provisions of Section 10(c) below, for purposes of this Lease, a Transfer shall include, without limitation, any assignment by operation of law, and any merger, consolidation, or asset sale involving Tenant, any direct or indirect transfer of control of Tenant, and any transfer of a majority of the ownership interests in Tenant. Consent by Landlord to any one Transfer shall be held to apply only to the specific Transfer authorized, and shall not be construed as a waiver of the duty of Tenant, or Tenant’s legal representatives or assigns, to obtain from Landlord consent to any other or subsequent Transfers pursuant to the foregoing, or as modifying or limiting the rights of Landlord under the foregoing covenant by Tenant. (b) Without limiting the bases upon which Landlord may reasonably withhold its consent to a proposed Transfer, it shall not be unreasonable for Landlord to withhold its consent if: (i) the proposed Transferee shall have a net worth that is not acceptable to Landlord in Landlord’s reasonable discretion, taking into account the remaining obligations under this Lease and the fact that Tenant is not released; (ii) the proposed Transferee, in Landlord’s reasonable opinion, is not reputable and of good character; (iii) the portion of the Premises requested to be subleased renders the balance of the Premises unleasable as a separate area; (iv) Tenant is proposing to Transfer to an existing tenant of the Building or another property owned by Landlord or Landlord’s affiliate(s), or to another prospect with whom Landlord or Landlord’s affiliate(s) are then actively negotiating for space in the Building or property located at 0000 Xxxxxx Xxxxxx Xxxx, 00000 Xxxxxxx Xxxxxx Xxxxx, or 00000 Xxxxxx Xxxxxx Xxxx (each of which is located in Herndon, Virginia); (v) the proposed Transferee would cause any of Landlord’s existing parking facilities to be reasonably inadequate, or in violation of code requirements, or require Landlord to increase the parking area or the number of parking spaces to meet code requirements; (vi) the proposed Transferee is a governmental or quasi-governmental agency; or (vii) the nature of such Transferee’s proposed business operation would or might reasonably violate the terms of this Lease or of any other lease for the Building (including any exclusivity provisions), or would, in Landlord’s reasonable judgment, otherwise be incompatible with other tenancies in the Building. (c) Notwithstanding anything to the contrary in this Lease, Tenant shall have the right without the prior consent of Landlord, but after at least 15 days’ prior written notice to Landlord, to make a Transfer to any Affiliate (as defined below), or an entity into which Tenant merges or that acquires substantially all of the assets or stock of Tenant (“Surviving Entity”); provided: (i) Tenant delivers to Landlord the Transfer Information (as defined below); (ii) the Surviving Entity shall have a tangible net worth at least equal to the net worth of Tenant on the date of this Lease or otherwise reasonably acceptable to Landlord taking into account the fact that the originally named Tenant is not being released; (iii) the originally named Tenant shall not be released or discharged from any liability under this Lease by reason of such Transfer, and the Permitted Transferee shall assume in writing all of the obligations and liabilities of Tenant under this Lease; (iv) the use of the Premises shall not change, and the Permitted Transferee, in Landlord’s reasonable opinion, shall be reputable and of good character befitting a class A office building; (v) such Transfer is for a good business purpose and not principally for the purpose of transferring the leasehold estate created by this Lease; and (vi) if the Transfer is to an Affiliate, such Transferee shall remain an Affiliate throughout the Term and if such Transferee shall cease being an Affiliate, Tenant shall notify Landlord in writing of such change and such Transfer shall be deemed an Event of Default if Landlord’s consent thereto is not given in writing within 10 business days after such notification. A Transfer described in the prior sentence is referred to herein as a “Permitted Transfer” to a “Permitted Transferee”. An “Affiliate” means a corporation, limited liability company, partnership, or other registered entity, 50% or

18 more of whose equity interest is owned by the same persons or entities owning 50% or more of Tenant’s equity interests, a subsidiary, or a parent corporation. (d) If at any time during the Term Tenant desires to complete a Transfer, Tenant shall give written notice to Landlord of such desire together with the Transfer Information. If: (i) Tenant desires to assign this Lease or to sublease the entire Premises for the remainder of the Term, other than pursuant to Section 10(c), Landlord shall have the right to accelerate the Expiration Date so that the Expiration Date shall be the date on which the proposed assignment or sublease would be effective; or (ii) Tenant desires to sublease more than fifty percent (50%) of the Premises other than to an Affiliate for the remainder of the Term, Landlord shall have the right to accelerate the Expiration Date with respect to (that is, recapture) the portion of the Premises that Tenant proposes to sublease (and in each case, a pro rata portion of Tenant’s parking rights shall also expire on such accelerated Expiration Date). If Landlord elects to accelerate the Expiration Date pursuant to this paragraph, Tenant shall have the right to rescind its request for Xxxxxxxx’s consent to the proposed assignment or sublease by giving written notice of such rescission to Landlord within 10 days after Xxxxxx’s receipt of Landlord’s acceleration election notice. If Tenant does not so rescind its request: (A) Tenant shall deliver the Premises or the applicable portion thereof to Landlord in the same condition as Tenant is, by the terms of this Lease, required to deliver the Premises to Landlord upon the Expiration Date; and (B) Fixed Rent and Tenant’s Share shall be reduced on a per rentable square foot basis for the area of the Premises that Tenant no longer leases. If Landlord elects to accelerate the Expiration Date for less than the entire Premises, the cost of erecting any demising walls, entrances, and entrance corridors, and any other improvements required in connection therewith shall be performed by Landlord, with the cost thereof being divided evenly between Landlord and Tenant. (e) The “Transfer Information” means the following information: (i) a copy of the fully executed assignment and assumption agreement, or sublease agreement, as applicable (with respect to a Permitted Transfer, such agreement to be delivered to Landlord within 10 business days after the transaction closes and with respect to all other Transfers, such agreement shall be provided in draft form and shall not be executed until Landlord’s consent has been given); (ii) a copy of the then-current financials of the Transferee (either audited or certified by the chief financial officer of the Transferee); and (iii) such other reasonably requested information by Xxxxxxxx needed to confirm or determine Tenant’s compliance with the terms and conditions of this Section. (f) Any sums or other economic consideration received by Tenant as a result of any Transfer (except rental or other payments received that are attributable to the amortization of the cost of leasehold improvements made to the transferred portion of the Premises by Tenant for the Transferee, and other reasonable expenses incident to the Transfer, including standard leasing commissions) whether denominated rentals under the sublease or otherwise, that exceed, in the aggregate, the total sums which Tenant is obligated to pay Landlord under this Lease (prorated to reflect obligations allocable to that portion of the Premises subject to such Transfer) shall, at Landlord’s option, either be retained by Tenant or, after first deducting any commercially reasonable abated rent, reasonable brokerage commissions actually paid by Xxxxxx and tenant improvement costs actually incurred by Tenant in connection with making the applicable portion of the Premises ready for the applicable transfer, divided evenly between Landlord and Tenant, with Landlord’s portion being payable to Landlord as Additional Rent without affecting or reducing any other obligation of Tenant hereunder. (g) Regardless of Landlord’s consent to a proposed Transfer, no Transfer shall release Tenant from Tenant’s obligations or alter Tenant’s primary liability to fully and timely pay all Rent when due from time to time under this Lease and to fully and timely perform all of Tenant’s other obligations under this Lease, and the originally named Tenant and all assignees shall be jointly and severally liable for all Tenant obligations under this Lease. The acceptance of rental by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. The joint and several liability of the

20 HVAC” means any supplemental HVAC system serving the Premises (regardless of who installed it). “Premises Water Heater” means any water heater serving the Premises (regardless of who installed it), including without limitation expansion tanks and any associated piping. Tenant shall maintain Tenant’s Supplemental HVAC under a service contract with a firm and upon such terms as may be reasonably satisfactory to Landlord, including inspection and maintenance on at least a semiannual basis, and provide Landlord with a copy thereof. Within 5 business days after Xxxxxxxx’s request, Tenant shall provide Landlord with evidence that such contract is in place. Further, Tenant shall ensure that all Premises Water Heaters have a working automatic water shut-off device with audible alarm and a leak pan underneath. All repairs to the Building and/or the Project made necessary by reason of the installation, maintenance, and operation of Tenant’s Supplemental HVAC, Premises Water Heaters, and Alterations shall be Tenant’s expense. In the event of an emergency, such as a burst waterline or act of God, Landlord shall have the right to make repairs for which Xxxxxx is responsible hereunder (at Tenant’s cost) without giving Tenant prior notice, but in such case Landlord shall provide notice to Tenant as soon as practicable thereafter, and Landlord shall take commercially reasonable steps to minimize the costs incurred. Further, Landlord shall have the right to make repairs for which Xxxxxx is responsible hereunder (at Xxxxxx’s cost) with prior notice to Tenant if Xxxxxxxx believes in its sole and absolute discretion that the repairs are necessary to prevent harm or damage to the Building, and Landlord shall take commercially reasonable steps to minimize the costs incurred. (b) Landlord, at Xxxxxxxx’s expense (except to the extent such expenses are includable in Project Expenses), shall, in a manner commensurate with that of other owners of first class office buildings in the Herndon area, make all necessary repairs to: (i) the footings and foundations and the structural elements of the Building; (ii) the roof of the Building; (iii) the HVAC (including maintenance and repair, but not replacement, which shall be Tenant’s responsibility at Tenant’s sole cost and expense, of any VAV boxes connected to the HVAC, provided that Tenant, at Tenant’s sole cost and expense, obtains and provides Landlord with a commission report with respect to the VAV boxes connected to the HVAC (y) prior to commencement of the Leasehold Improvements and allows Landlord to make repairs to the VAV boxes connected to the HVAC that are necessary as result of such commission report, and (z) within 10 days after completion of the Leasehold Improvements), plumbing, elevators (if any), electric, fire protection and fire alert systems within the Building core from the core to the point of connection for service to the Premises, but specifically excluding Tenant’s Supplemental HVAC, Premises Water Heaters, and Alterations; (iv) the Building exterior; and (v) the Common Areas (collectively, “Landlord Repairs”). During the Term, Landlord also shall, the costs and expenses of which shall be included in Project Expenses (to the extent such costs and expenses are includable in Project Expenses): (y) keep the Common Areas clean; and (z) maintain the Common Areas, the structural elements of the Building, the roof of the Building, and the HVAC, plumbing, water, sewer, elevators (if any), electric, fire protection and fire alert systems within the Building core from the core to the point of connection for service to the Premises, but specifically excluding Tenant’s Supplemental HVAC, Premises Water Heaters, and Alterations, in a manner befitting a first-class office building located in the Herndon area and in compliance with all applicable Laws. Any provision of this Lease to the contrary notwithstanding, any repairs to the Project or any portion thereof made necessary by the negligent or willful act or omission of, or default under this Lease by, Tenant or any Tenant Agent shall be made at Tenant’s expense, subject to the waivers set forth in Section 12(g). (c) The parties agree it is in their mutual best interest that the Building and Premises be operated and maintained in a manner that is environmentally responsible, fiscally prudent, and provides a safe and productive work environment. Accordingly, Tenant shall use commercially reasonable efforts to conduct its operations in the Building and within the Premises to: (1) minimize to the extent reasonably feasible: (i) direct and indirect energy consumption and greenhouse gas emissions; (ii) water consumption; (iii) the amount of material entering the waste stream; and (iv) negative impacts upon the indoor air quality of the Building; and (2) permit the Building to maintain its LEED rating and an Energy Star label, to the extent applicable. Landlord shall use commercially reasonable efforts to operate and maintain the Common

22 Additional Insured is an insured, whether such other insurance is primary, excess, self-insurance, or insurance on any other basis, which must cause the umbrella/excess coverage to be vertically exhausted, whereby such coverage is not subject to any “Other Insurance” provision under Tenant’s umbrella/excess liability policy. The limits of liability may be satisfied by a combination of primary and excess liability insurance. (v) property insurance written on an ISO CP 10 30-Cause of Loss-Special Form, or its then-commercially available equivalent, including, but not limited to, coverage against damage due to fire, windstorm, cyclone, tornado, hail, explosion, riot, civil commotion, aircraft, vehicle, smoke damage, vandalism, and malicious mischief insuring all present and future Tenant’s Property leased by or in the care, custody, and control of Tenant and located in the Premises in an amount of no less than the full replacement cost thereof, with an agreed amount endorsement (waiving applicable co-insurance clause). “Tenant’s Property” means Tenant’s trade fixtures, furniture, equipment, personal property, signage, Specialty Alterations (as defined in Section 18(b)), and telephone, security, and communication equipment system wiring and cabling. Tenant shall not self-insure. Tenant shall neither have, nor make, any claim against Landlord, and Landlord shall not be responsible or liable to Tenant or those claiming by, through, or under Tenant, for any loss or damage resulting to Tenant or those claiming by, through, or under Tenant, or its or their property, including without limitation Tenant’s Property, regardless of the cause of the loss or damage, including, without limitation, fire, explosion, falling plaster, steam, gas, air contaminants or emissions, electricity, electrical or electronic emanations or disturbance, water, rain, snow, or leaks from any part the Building or from the pipes, appliances, equipment, or plumbing works or from the roof or from any other place, nor shall Landlord be liable for any loss of or damage to property of Tenant, including without limitation Tenant’s Property, or of others entrusted to employees of Landlord. (vi) business interruption insurance covering any loss due to the occurrence of any of the hazards required to be insured against by Tenant pursuant to this Lease, in an amount sufficient to cover Tenant’s monetary obligations under this Lease for a period of at least 12 months. (vii) boiler and machinery, if there is a boiler, supplemental air conditioning unit, or pressure object or similar equipment in the Premises. When applicable, this insurance coverage requirement may be satisfied through the special cause of loss coverage required in Section 12(b)(v). (c) All insurance policies required of Tenant under this Lease, including ongoing and products-completed operations coverage but exclusive of workers’ compensation, shall name: Landlord and Brandywine Realty Trust, and their members, partners, joint venturers, shareholders, officers, employees, agents, mortgagees, ground lessors, affiliates, and property managers, and their respective officers, members, partners, directors, shareholders, employees, and agents, together with their successors and assigns as their interest may appear, and any other associated or affiliated entity as their interests appear (collectively, “Additional Insureds”), each as an additional insured. All such coverages shall be primary, and any other insurance that may be available to Landlord and any Additional Insured will be excess and noncontributory. (d) Prior to the Commencement Date (or Xxxxxx’s earlier accessing of the Premises), Tenant shall provide Landlord and/or Landlord’s designated agent with certificates that evidence that all insurance coverages required under this Lease are in place for the policy periods. Tenant shall also furnish to Landlord and/or Landlord’s designated agent throughout the Term replacement certificates at least 15 days prior to the expiration dates of the then-current policy or policies or, upon request by Landlord and/or Xxxxxxxx’s designated agent from time to time, sufficient information to evidence that the insurance required under this Section is in full force and effect. In addition, Tenant shall provide Landlord and/or Landlord’s designated agent with at least 15 days’ prior written notice of cancelation or material alteration all such policies. Tenant shall include a waiver of the insurer’s right of subrogation against Landlord and

23 Additional Insureds during the Term in each of Tenant’s liability and workers’ compensation policies. If Tenant fails to provide Landlord and/or Landlord’s designated agent with a requested insurance certificate as required under this Lease within 30 days after receipt of Landlord’s written request therefor, Tenant shall pay to Landlord a fee equal to $25.00 for each day that elapses after such 30-day period until Landlord and/or Landlord’s designated agent receives the requested certificate. In no event will any acceptance of certificates of insurance by Landlord, or failure of Tenant to provide certificates of insurance as required hereunder, be construed as a waiver or limitation of Tenant’s obligations to maintain insurance coverage pursuant to this Section 12. All insurance required under this Lease shall be issued by an insurance company that has been in business for at least 5 years, is authorized to do business in the State, and is rated “A-/X” or greater by A.M. Best’s Insurance Reports or any successor publication of comparable standing. The limits of any such required insurance shall not in any way limit Tenant’s liability under this Lease or otherwise. If Tenant fails to maintain such insurance, Landlord may, but shall not be required to, procure and maintain the same, at Tenant’s expense, which expense shall be reimbursed by Xxxxxx as Additional Rent within 10 days after written demand. The deductible or self-insured retention amount required under any insurance policy maintained by Tenant shall be the sole responsibility of Tenant and not exceed $25,000, unless otherwise approved by Landlord in writing. (e) Tenant shall enter a written contract with its movers and other vendors that requires them to: (i) procure insurance appropriate to the applicable risk and satisfactory to Landlord; (ii) endorse its policies with the Additional Insureds as additional insureds (except workers compensation); and (iii) be primary and noncontributory to any insurance carried by an Additional Insured. However, in no event will the mover and other vendors carry insurance coverages and limits less than the following: (i) commercial general liability insurance - $1,000,000 per occurrence, $2,000,000 general aggregate, $2,000,000 products-completed operations; (ii) commercial auto liability insurance for all owned, non-owned, and hired autos in a limit of $1,000,000 per accident; and (iii) workers compensation insurance as required by statute. Tenant shall deliver to Landlord and/or Landlord’s designated agent a certificate of insurance naming each Additional Insured as an additional insured, which policies shall be primary and any other insurance that may be available to Landlord and any Additional Insured will be excess and noncontributory. (f) Landlord shall obtain and maintain, or cause to be obtained or maintained, the following insurance during the Term: (i) replacement cost insurance including “all risk” property insurance on the Building, including without limitation leasehold improvements (exclusive of Tenant’s Property); (ii) commercial general liability insurance (including bodily injury and property damage) covering Landlord’s operations at the Project in amounts reasonably required by Landlord or any Mortgagee (as defined in Section 16); and (iii) such other insurance as reasonably required by Landlord or any Mortgagee. (g) Landlord and Tenant shall each include in each of its property insurance policies (as required above) a waiver of the insurer’s right of subrogation against the other party during the Term (and any period of Tenant’s access to the Premises prior to the Commencement Date), and consent to a waiver of right of recovery pursuant to the terms of this paragraph. Both Landlord and Tenant agree to promptly give each insurance company which has issued to it policies of insurance written notice of the terms of such mutual waivers and to cause such insurance policies to be properly endorsed, if necessary, to prevent the invalidation thereof by reason of such waivers. Notwithstanding anything to the contrary in this Lease: (i) each party hereby waives, releases, and agrees not to make any claim against or seek to recover from, the other party with respect to any claim (including a claim for negligence) that such party might otherwise have against the other party for loss, damage, or destruction with respect to its property occurring during the Term (or any period of Tenant’s access to the Premises prior to the Commencement Date) to the extent to which such party is, or is required to be, insured under a policy or policies containing a waiver of subrogation or permission to release liability; and (ii) all waivers of subrogation and rights of recovery required hereunder shall also apply to each of the waiving party’s insurance policies’ deductible(s)/self- insured retention(s). Nothing contained in this Section 12(g) shall be deemed to relieve either party of any

28 (i) Landlord shall have the right to terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and Tenant shall pay Landlord upon demand for all losses and damages that Landlord suffers or incurs by reason of such termination, including damages in an amount equal to the total of: (A) the costs of repossessing the Premises and all other expenses incurred by Landlord in connection with Xxxxxx’s default, plus the Administrative Fee; (B) the unpaid Rent earned as of the date of termination; (C) an amount equal to (i) all Rent for the period that would otherwise have constituted the remainder of the Term, less (ii) the fair market rental value of the Premises for the remainder of the Term, discounted to present value at a rate of 2% per annum; and (D) all other sums of money and damages owing by Tenant to Landlord. The “Administrative Fee” means 15% of the costs incurred by Landlord in curing Tenant’s default or performing Tenant’s obligations hereunder. (ii) Landlord shall have the right to terminate Xxxxxx’s right of possession (but not this Lease) and may repossess the Premises by forcible detainer or forcible entry and detainer suit or otherwise, without demand or notice of any kind to Tenant and without terminating this Lease. If Xxxxxx receives written notice of a termination of its right to possession, such notice will serve as both a notice to vacate, notice to pay or quit, and a demand for possession of, the Premises, and Landlord may immediately thereafter initiate a forcible detainer action without any further demand or notice of any kind to Tenant. (iii) Landlord shall have the right, pursuant to applicable judicial process, to enter and take possession of all or any portion of the Premises without electing to terminate this Lease, in which case Landlord shall have the right to relet all, or any portion of the Premises on such terms as Landlord deems advisable. Landlord will not be required to incur any expenses to relet all or any portion of the Premises, although Landlord may at its option incur customary leasing commissions or other costs for the account of Tenant as Landlord shall deem necessary or appropriate to relet. In no event will the failure of Landlord to relet all or any portion of the Premises reduce Tenant’s liability for Rent or damages. Upon the occurrence of an Event of Default, Landlord shall use commercially reasonable efforts to mitigate its damages. However, Landlord shall not be required to give any special preference or priority to reletting the Premises over other vacant space in the Building, Landlord shall be deemed to have used commercially reasonable efforts if it uses the same efforts in marketing the Premises as used in marketing other vacant space at the Building, and in no event shall Landlord be responsible or liable for any failure to relet the Premises or any part thereof, or for any failure to collect any rent due upon a reletting. Xxxxxxxx’s rejection of a prospective replacement tenant based on an offer of rentals below Landlord’s published rates for new leases of comparable space at the Building at the time in question, or below the rates provided in this Lease or containing terms less favorable than those contained herein, shall not give rise to a claim by Xxxxxx that Landlord failed to mitigate its damages. (iv) Landlord shall have the right, pursuant to applicable judicial process, to enter the Premises without terminating this Lease and without being liable for prosecution or any claim for damages therefor and maintain the Premises and repair or replace any damage thereto or do anything for which Xxxxxx is responsible hereunder. Tenant shall reimburse Landlord immediately upon demand for any out-of-pocket costs which Landlord incurs in thus effecting Tenant’s compliance under this Lease, and Landlord shall not be liable to Tenant for any damages with respect thereto. (v) Landlord shall have the right to continue this Lease in full force and effect, whether or not Tenant shall have abandoned the Premises. If Landlord elects to continue this Lease in full force and effect pursuant to this Section, then Landlord shall be entitled to enforce all of its rights and remedies under this Lease, including the right to recover Rent as it becomes due. Xxxxxxxx’s election not to terminate this Lease pursuant to this Section or pursuant to any other provision of this Lease, at law or in equity, shall not preclude Landlord from showing the Premises to potential tenants, subsequently electing to terminate this Lease, or pursuing any of its other remedies.

29 (c) Upon the occurrence of an Event of Default, Tenant shall be liable to Landlord for, and Landlord shall be entitled to recover: (i) all Rent accrued and unpaid; (ii) all costs and expenses incurred by Landlord in recovering possession of the Premises, including legal fees, and removal and storage of Tenant’s Property; (iii) the costs and expenses of restoring the Premises to the condition in which the same were to have been surrendered by Tenant as of the Expiration Date; (iv) the costs of reletting commissions; (v) all reasonable legal fees and court costs incurred by Landlord in connection with the Event of Default; and (vi) the unamortized portion (as reasonably determined by Xxxxxxxx) of brokerage commissions and consulting fees incurred by Landlord, and tenant concessions including free rent and allowances given by Xxxxxxxx, in connection with this Lease. Upon the occurrence of an Event of Default and notwithstanding Section 1(a) above, the monthly Fixed Rent payable for the Abatement Period shall equal the amount of Fixed Rent payable immediately following the expiration of the Abatement Period. (d) Any amount payable by Tenant under this Lease that is not paid when due shall bear interest at the rate of 1% per month until paid by Tenant to Landlord. If Tenant fails to pay Rent when due on 3 or more occasions during the Term, Landlord shall have the right to require Tenant to pay all future Rent by ACH debit of funds, in which case Tenant shall complete Landlord’s then-current forms authorizing Landlord to automatically xxxxx Xxxxxx’s bank account. Notwithstanding the foregoing, upon Xxxxxx’s written request, no interest shall be assessed against Tenant the first 2 times in any 12 month period that Tenant is late making any payment under this Lease, provided Tenant makes the required payment within 3 business days after receipt of notice of such late payment. (e) Neither any delay or forbearance by Landlord in exercising any right or remedy hereunder nor Landlord’s undertaking or performing any act that Landlord is not expressly required to undertake under this Lease shall be construed to be a waiver of Landlord’s rights or to represent any agreement by Landlord to thereafter undertake or perform such act. Landlord’s waiver of any breach by Tenant of any covenant or condition herein contained (which waiver shall be effective only if so expressed in writing by Landlord) or Landlord’s failure to exercise any right or remedy in respect of any such breach shall not constitute a waiver or relinquishment for the future of Landlord’s right to have any such covenant or condition duly performed or observed by Tenant, or of Landlord’s rights arising because of any subsequent breach of any such covenant or condition, nor bar any right or remedy of Landlord in respect of such breach or any subsequent breach. Tenant hereby expressly waives, for itself and all persons claiming by, through or under it, any right of redemption, reentry, or restoration of the operation of this Lease under any present or future Law, including without limitation any such right which Tenant would otherwise have in case Tenant shall be dispossessed for any cause, or in case Landlord shall obtain possession of the Premises as herein provided. (f) If Tenant defaults in the performance of any covenant, agreement, term, provision, or condition contained in this Lease, Landlord, in addition to any other rights and remedies it has under this Lease and without thereby waiving such default, may perform the same for the account of and at the expense of Tenant (but shall not be obligated to do so), without notice in a case of emergency and in any other case if such default continues after 5 days from the date that Landlord gives written notice to Tenant of its intention to do so. Landlord may invoice Tenant for all amounts paid by Landlord and all losses, costs, and expenses incurred by Landlord in connection with any such performance by Landlord pursuant to this paragraph, plus the Administrative Fee, including, without limitation, all amounts paid and costs and expenses incurred by Landlord for any property, material, labor, or services provided, furnished, or rendered, or caused to be provided, furnished, or rendered, by Landlord to Tenant (together with interest at the rate of 1% per month from the date Landlord pays the amount or incurs the loss, cost, or expense until the date of full repayment by Tenant) monthly or immediately, at Landlord’s option, and shall be due and payable by Tenant to Landlord as Additional Rent within 5 days after Xxxxxx receives the invoice. Any reservation of a right by Landlord to enter upon the Premises and to make or perform any repairs, alterations,

30 or other work in, to, or about the Premises, which, in the first instance, is Xxxxxx’s obligation pursuant to this Lease, shall not be deemed to impose any obligation on Landlord to do so, render Landlord liable to Tenant or any third party for the failure to do so, or relieve Tenant from any obligation to indemnify Landlord as otherwise provided elsewhere in this Lease. (g) The rights granted to Landlord in this Section shall be cumulative of every other right or remedy provided in this Lease or which Landlord may otherwise have at law or in equity or by statute, and the exercise of one or more rights or remedies shall not prejudice or impair the concurrent or subsequent exercise of other rights or remedies or constitute a forfeiture or waiver of Rent or damages accruing to Landlord by reason of any Event of Default under this Lease. Landlord shall have all rights and remedies now or hereafter existing at law or in equity with respect to the enforcement of Tenant’s obligations hereunder and the recovery of the Premises. No right or remedy herein conferred upon or reserved to Landlord shall be exclusive of any other right or remedy, but shall be cumulative and in addition to all other rights and remedies given hereunder or now or hereafter existing at law or in equity. Landlord shall be entitled to seek injunctive relief in case of the violation, or attempted or threatened violation, of any covenant, agreement, condition, or provision of this Lease, or to a decree compelling performance of any covenant, agreement, condition, or provision of this Lease. (h) No payment by Tenant or receipt by Landlord of a lesser amount than any payment of Fixed Rent or Additional Rent herein stipulated shall be deemed to be other than on account of the earliest stipulated Fixed Rent or Additional Rent due and payable hereunder, nor shall any endorsement or statement or any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction. Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other right or remedy provided for in this Lease, at law or in equity, and acceptance of such partial payment shall be deemed subject to Landlord’s reservation of all rights. Landlord shall have no obligation to accept any cure proffered by Tenant after an Event of Default. (i) Landlord hereby waives any applicable common law or statutory liens upon all goods, wares, equipment, fixtures, furniture, improvements, and other personal property of Tenant which may hereafter be situated on the Premises. Upon request by Xxxxxx, Xxxxxxxx shall agree to subordinate any common law or statutory lien to any commercial lender to whom Tenant grants a security interest. Nothing herein shall be deemed to prevent the abandonment of property as set forth in Section 18(b). Upon the occurrence of an Event of Default by Tenant, and pursuant to applicable judicial process, Landlord may, in addition to any other remedies provided herein, peaceably enter upon the Premises and take possession of any and all goods, wares, equipment, fixtures, furniture, improvements, and other personal property of Tenant situated on the Premises, without liability for trespass or conversion, and sell the same at public or private sale, with or without having such property at the sale, after giving Tenant reasonable notice of time and place of any public sale or of the time after which any private sale is to be made, at which sale Landlord or its assigns may purchase unless otherwise prohibited by law. Unless otherwise provided by law, and without intending to exclude any other manner of giving Tenant reasonable notice, the requirement of reasonable notice shall be met if such notice is given in the manner prescribed in Section 21 at least 5 days before the time of sale. The proceeds from any such disposition, less all expenses connected with the taking of possession, holding, and selling of the property (including reasonable attorneys’ fees and other expenses), shall be applied as a credit against the indebtedness secured by the security interest granted in this paragraph. Any surplus shall be paid to Tenant or as otherwise required by law, and Tenant shall pay any deficiencies forthwith. (j) Tenant waives the right to any notices to quit as may be specified in Virginia Code § 55.1-1415, as amended, or any similar or successor provision of Law, and agrees that 3 days’ notice shall be sufficient in any case where a longer period may be statutorily specified.

33 only brings a reasonable quantity of such supplies and products onto the Premises and Tenant shall at all times comply with all Laws pertaining to the storage, handling, use, disposal, and application of such supplies and products, and all Laws pertaining to the communication to employees and other third parties of any hazards associated with such supplies and products. Tenant shall not install any underground or above ground tanks on the Project. Tenant shall not cause or permit to exist any release, spillage, emission, or discharge of any Hazardous Material on or about the Project (“Release”). In the event of a Release, Tenant shall immediately notify Landlord both orally and in writing, report such Release to the relevant government agencies as required by applicable Law, and promptly remove the Hazardous Material and otherwise investigate and remediate the Release in accordance with applicable Law and to the satisfaction of Landlord. Landlord shall have the right, but not the obligation, to enter upon the Premises to investigate and/or remediate the Release in lieu of Tenant, and Tenant shall reimburse Landlord as Additional Rent for the costs of such remediation and investigation. Tenant shall promptly notify Landlord if Tenant acquires knowledge of the presence of any Hazardous Material on or about the Premises, except as Tenant is permitted to bring onto the Premises under this Lease. Landlord shall have the right at all reasonable times upon reasonable advance notice or, in the case of an emergency, at any time without notice, to inspect and assess the Premises for the purpose of determining whether Tenant is handling any Hazardous Material in violation of this Lease or applicable Law, or to ascertain the presence of any Release. This subsection shall survive the Expiration Date. (b) Tenant shall, and shall cause Tenant Agents to, use the Premises in compliance with all applicable Laws. Tenant shall comply with all present and future Laws concerning the use, occupancy, and condition of the Premises and all machinery, equipment, furnishings, fixtures, and improvements therein, all of which shall be complied with in a timely manner at Tenant’s sole cost and expense. Without limiting the generality of the foregoing, Tenant shall: (i) obtain, at Tenant’s expense, before engaging in Tenant’s business or profession within the Premises, all necessary licenses and permits including, but not limited to, state and local business licenses, and permits; and (ii) remain in compliance with and keep in full force and effect at all times all licenses, consents, and permits necessary for the lawful conduct of Tenant’s business or profession at the Premises. Tenant shall pay all personal property taxes, income taxes, gross receipts taxes, and other taxes, assessments, duties, impositions, and similar charges that are or may be assessed, levied, or imposed upon Tenant, Xxxxxx’s business, or Xxxxxx’s Property. Tenant shall also comply with all applicable Laws that do not relate to the physical condition of the Premises and with which only the occupant can comply, such as laws governing maximum occupancy, workplace smoking, VDT regulations, and illegal business operations, such as gambling. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial, governmental or regulatory action, regardless of whether Landlord is a party thereto, that Xxxxxx has violated any of such Laws shall be conclusive of that fact as between Landlord and Tenant. (c) Notwithstanding anything to the contrary in this Lease, if the requirement of any public authority obligates either Landlord or Tenant to expend money in order to bring the Premises and/or any area of the Project into compliance with Laws as a result of: (i) Tenant’s particular use of the Premises or the use or occupancy of the Premises for other than general office use; (ii) Alterations or Leasehold Improvements; (iii) Tenant’s change in the use of the Premises; (iv) the manner of conduct of Tenant’s business or operation of its installations, equipment, or other property therein; (v) any cause or condition created by or at the request or direction of Tenant or any Tenant Agent, other than by Xxxxxxxx’s performance of any work for or on behalf of Tenant; or (vi) breach of any of Tenant’s obligations hereunder, then Tenant shall bear all costs of bringing the Premises and/or Project into compliance with Laws, whether such costs are related to structural or nonstructural elements of the Premises or Project, and in such event Tenant at its sole cost and expense shall be solely responsible for taking any and all measures that are required to comply with such Laws concerning the Building and the Premises (including point of entry and means of ingress and egress thereto) and the business conducted therein.

38 hold harmless the other from and against any and all claims, damages, losses, risks, liabilities, and expenses (including reasonable attorneys’ fees and costs) incurred by the other to the extent arising from or related to any breach of the foregoing certifications. The foregoing indemnity obligations shall survive the Expiration Date. (m) Except as set forth in this paragraph, neither Tenant nor Landlord shall issue, or permit any broker, representative, or agent representing either party in connection with this Lease to issue: (i) any press release; or (ii) any other public disclosure regarding the specific terms of this Lease (or any amendments or modifications hereof), without the prior written approval of the other party. The parties acknowledge that the transaction described in this Lease and the terms thereof (but not the existence thereof) are of a confidential nature and shall not be disclosed except to such party’s employees, attorneys, accountants, consultants, advisors, affiliates, and actual and prospective purchasers, lenders, investors, subtenants and assignees (collectively, “Permitted Parties”), and except as, in the good faith judgment of Landlord or Tenant, may be required to enable Landlord or Tenant to comply with its obligations under Law (and, to the extent such disclosure is being made in compliance with Law, upon prior notice to the other party to the extent permitted). In connection with the negotiation of this Lease and the preparation for the consummation of the transactions contemplated hereby, each party acknowledges that it will have had access to confidential information relating to the other party. Each party shall treat such information and shall cause its Permitted Parties to treat such confidential information as confidential, and shall preserve the confidentiality thereof, and not duplicate or use such information, except by Permitted Parties. Notwithstanding the foregoing, Landlord shall have the right, to the extent required to be disclosed by Landlord or Landlord’s affiliates in connection with filings required by applicable Laws, including the Securities and Exchange Commission (“SEC”), and similar regulatory frameworks, without notice to Tenant to include in such securities filings general information relating to this Lease, including, without limitation, Tenant’s name, the Building, and the square footage of the Premises. (n) Neither Tenant, nor anyone acting through, under, or on behalf of Xxxxxx, shall have the right to record this Lease, nor any memorandum, notice, affidavit, or other writing with respect thereto, or otherwise file this Lease with any governmental authority. (o) Tenant shall not claim any money damages by way of setoff, counterclaim, or defense, based on any claim that Landlord unreasonably withheld its consent, in which case Tenant’s sole and exclusive remedy shall be an action for specific performance, injunction, or declaratory judgment. (p) All requests made to Landlord to perform repairs or furnish services, supplies, utilities, or freight elevator usage (if applicable), shall be made online to the extent available (currently such requests shall be made via xxxxx://xxxxxxx.xxxxxxxxxxxxxxxx.xxx/, as the same may be modified by Landlord from time to time) otherwise via email or written communication to Xxxxxxxx’s property manager for the Building. Whenever Tenant requests Landlord to take any action not required of Landlord under this Lease or give any consent required or permitted to be given by Landlord under this Lease (for example, a request for a Transfer consent, a consent to an Alteration, or a subordination of Landlord’s lien, but other than a request for services, supplies, or utilities which is governed by Section 7(b)), Tenant shall pay to Landlord for Landlord’s administrative and/or professional costs in connection with each such action or consent Landlord’s reasonable costs incurred by Landlord in reviewing and taking the proposed action or consent, including reasonable attorneys’, engineers’ and/or architects’ fees (as applicable), plus the Administrative Fee. The foregoing amount shall be paid by Tenant to Landlord within 30 days after Xxxxxxxx’s delivery to Tenant of an invoice for such amount. Tenant shall pay such amount without regard to whether Xxxxxxxx takes the requested action or gives the requested consent. (q) Tenant acknowledges and agrees that Landlord shall not be considered a “business associate” for any purpose under the Health Insurance Portability and Accountability Act of 1996 and all

39 related implementing regulations and guidance. (r) Tenant shall cause any work performed on behalf of Tenant to be performed by contractors who work in harmony, and shall not interfere, with any labor employed by or on behalf of Landlord or Xxxxxxxx’s contractors. If at any time any of the contractors performing work on behalf of Xxxxxx does not work in harmony or interferes with any labor employed by or on behalf of Landlord, other tenants, or their respective mechanics or contractors, then the permission granted by Landlord to Tenant for such contractors to do or cause any work to be done in or about the Premises may be withdrawn by Landlord with 48 hours’ written notice to Tenant. (s) This Lease may be executed in any number of counterparts, each of which shall be deemed to be an original as against any party whose signature appears thereon, and all of which shall together constitute one and the same instrument. The submission of this Lease by Landlord to Tenant for examination does not constitute a reservation of or option for the Premises or of any other space within the Building or in other buildings owned or managed by Landlord or its affiliates. This Lease shall not be binding nor shall either party have any obligations or liabilities or any rights with respect hereto, or with respect to the Premises, unless and until both parties have executed and delivered this Lease. The parties acknowledge and agree that notwithstanding any law or presumption to the contrary, the exchange of copies of this Lease and signature pages by electronic transmission shall constitute effective execution and delivery of this Lease for all purposes, and signatures of the parties hereto transmitted and/or produced electronically shall be deemed to be their original signature for all purposes. (t) Landlord and persons authorized by Landlord may enter the Premises at all reasonable times upon reasonable advance notice or, in the case of an emergency, at any time without notice. Landlord shall not be liable for inconvenience to or disturbance of Tenant by reason of any such entry; provided, however, whenever exercising its rights under this Section 25(t), Landlord shall do so, so far as practicable, so as to not unreasonably interfere with Xxxxxx’s use of the Premises. Landlord shall have the absolute right at all times, including an emergency situation, to limit, restrict, or prevent access to the Building in response to an actual, suspected, perceived, or publicly or privately announced health or security threat. (u) If more than one person or entity executes this Lease as Tenant, each of them is jointly and severally liable for the keeping, observing, and performing of all of the terms, covenants, conditions, provisions, and agreements of this Lease to be kept, observed, and performed by Xxxxxx. (v) TO THE EXTENT PERMITTED BY APPLICABLE LAW, LANDLORD AND TENANT HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER AGAINST THE OTHER ON ANY MATTER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE AS AMENDED FROM TIME TO TIME, THE RELATIONSHIP OF LANDLORD AND TENANT, OR TENANT’S USE OR OCCUPANCY OF THE BUILDING, ANY CLAIM OR INJURY OR DAMAGE, OR ANY EMERGENCY OR OTHER STATUTORY REMEDY WITH RESPECT THERETO. TENANT WAIVES ANY RIGHT TO RAISE ANY NONCOMPULSORY COUNTERCLAIM IN ANY SUMMARY OR EXPEDITED ACTION OR PROCEEDING INSTITUTED BY LANDLORD. LANDLORD, TENANT, ALL GUARANTORS, AND ALL GENERAL PARTNERS EACH WAIVES ANY OBJECTION TO THE VENUE OF ANY ACTION FILED IN ANY COURT SITUATED IN THE JURISDICTION IN WHICH THE BUILDING IS LOCATED, AND WAIVES ANY RIGHT, CLAIM, OR POWER UNDER THE DOCTRINE OF FORUM NON CONVENIENS OR OTHERWISE TO TRANSFER ANY SUCH ACTION TO ANY OTHER COURT. 26. REIT.

41 Rent on 100% of the Premises for the conduct of Tenant’s business, Tenant shall have the right to extend the Term (“Extension Option”) for 60 months beyond the end of the Initial Term (“Extension Term”) by delivering Tenant’s written extension election notice (“Extension Notice”) to Landlord no later than the Extension Deadline and no earlier than 6 months prior to the Extension Deadline, with time being of the essence. “Extension Deadline” means the date that is 12 months prior to the expiration of the Initial Term. If an Event of Default exists at any time after Landlord receives the Extension Notice but before the first day of the Extension Term, then Landlord, at Landlord’s option, shall have the right to nullify Tenant’s exercise of the Extension Option. The terms and conditions of this Lease during the Extension Term shall remain unchanged except Tenant shall only be entitled to the one Extension Term provided above, the annual Fixed Rent for the Extension Term shall be the Extension Rent (as defined below), the Expiration Date shall be the last day of the Extension Term (or such earlier date of termination of this Lease pursuant to the terms hereof), and, except to the extent reflected in the Extension Rent, Landlord shall have no obligation to perform any tenant improvements to the Premises or provide any tenant improvement allowance to Tenant. Upon Xxxxxx’s delivery of the Extension Notice, Tenant may not thereafter revoke its exercise of the Extension Option. Notwithstanding anything to the contrary in this Lease, Tenant shall have no right to extend the Term other than or beyond the one, 60-month Extension Term described in this paragraph. (b) “Extension Rent” means the fair market extension term base rent for space comparable to the Premises in comparable buildings in the market in which the Building is located. In determining the Extension Rent, Landlord, Tenant and any broker shall take into account all relevant factors including, without limitation, prevailing market allowances and concessions for renewing tenants, space measurement methods and loss factors, the lease term, the size of the space, the location of the building(s), parking charges, the amenities offered at the building(s), the age of the building(s), and whether Project Expenses and other pass-through expenses are on a triple net, base year, expense stop or other basis. In lieu of directly providing any prevailing market allowances and/or concessions, Landlord may elect to reduce the Extension Rent by the economic equivalent thereof to reflect the fact that such allowances and concessions were not provided directly to Tenant. During the Extension Term, Tenant shall not be entitled to any tenant improvement allowances, free rent periods, or other economic concessions (if any) that Tenant was entitled to during the prior Term, except to the extent such items are indirectly incorporated into the Extension Rent as set forth in this Section. When the Extension Rent is being determined for the first year of the Extension Term, the Extension Rent for the second and all subsequent years of the Extension Term shall also be determined in accordance with the same procedures as are set forth herein and based upon the then-prevailing annual rent escalation factor in the applicable leasing market. (c) If Tenant timely exercises the Extension Option and Landlord and Tenant do not agree upon the Extension Rent in writing by the date that is the later of 30 days after Xxxxxxxx’s receipt of the Extension Notice or 3 months prior to the Extension Deadline, then within 15 days after either party notifies the other in writing that such notifying party desires to determine the Extension Rent in accordance with the procedures set forth in this Section, Landlord and Tenant shall each deliver to the other party a written statement of such delivering party’s determination of the Extension Rent, together with such supporting documentation as the delivering party desires to deliver. Within 10 days after such 15-day period, Landlord and Tenant shall appoint a licensed real estate broker having a minimum of 10 years’ experience in commercial office leases in the market in which the Building is located who shall select either Landlord’s determination or Tenant’s determination, whichever the broker finds more accurately reflects the Extension Rent. The broker shall be instructed to notify Landlord and Tenant of such selection within 10 days after such broker’s appointment. The broker shall have no power or authority to select any Extension Rent other than the Extension Rent submitted by Landlord or Tenant nor shall the broker have any power or authority to modify any of the provisions of this Lease, and the decision of the broker shall be final and binding upon Landlord and Tenant. If Landlord and Tenant do not timely agree in writing upon the appointment of the broker, Landlord shall submit to Tenant the names of three qualified brokers licensed

44 such currently available ROFO Space after the date of this Lease and the term of that lease has expired (including, without limitation, the expiration of any lease term extension period(s), regardless of whether the extension right or agreement is contained in such lease or is agreed to at any time by Landlord and the tenant under such lease or otherwise) or been terminated. (d) (i) Fixed Rent for the first year that Tenant leases the ROFO Space shall be at the ROFO Rent (as defined below) multiplied by the number of rentable square feet in the ROFO Space. When Fixed Rent for the first year that Tenant will lease the ROFO Space is being determined, Fixed Rent for the second and all subsequent years that Tenant will lease the ROFO Space shall also be determined (in accordance with the same procedures as are set forth herein for determining the ROFO Rent) based upon the then-prevailing annual rent escalation factor in the applicable leasing market. (ii) “ROFO Rent” means the fair market expansion base rent for space comparable to the ROFO Space in comparable buildings in the market in which the Building is located. In determining the ROFO Rent, Landlord, Tenant and any broker shall take into account all relevant factors including, without limitation, prevailing market allowances and concessions for expanding tenants, space measurement methods and loss factors, the lease term, the size of the space, the location of the building(s), the amenities offered at the building(s), the age of the building(s), and whether operating expenses and other pass-through expenses are on a triple net, base year, expense stop or other basis. In lieu of directly providing any prevailing market allowances and/or concessions, Landlord may elect to reduce the ROFO Rent by the economic equivalent thereof to reflect the fact that such allowances and concessions were not provided directly to Tenant. (iii) If Landlord and Tenant do not agree upon the ROFO Rent in writing within 20 days after Xxxxxxxx receives Xxxxxx’s ROFO Notice, then within 15 days after either party notifies the other in writing that such notifying party desires to determine the ROFO Rent in accordance with the procedures set forth in this Section, Landlord and Tenant shall each deliver to the other party a written statement of such delivering party’s determination of the ROFO Rent, together with such supporting documentation as the delivering party desires to deliver. Within 10 days after such 15-day period, Landlord and Tenant shall appoint a real estate broker having a minimum of 10 years’ experience in the market in which the Building is located who shall select either Landlord’s determination or Tenant’s determination, whichever the broker finds more accurately reflects the ROFO Rent. The broker shall be instructed to notify Landlord and Tenant of such selection within 10 days after such broker’s appointment. The broker shall have no power or authority to select any ROFO Rent other than the ROFO Rent submitted by Landlord or Tenant nor shall the broker have any power or authority to modify any of the provisions of this Lease, and the decision of the broker shall be final and binding upon Landlord and Xxxxxx. If Landlord and Tenant do not timely agree in writing upon the appointment of the broker, Landlord shall submit to Tenant the names of 3 qualified brokers with a minimum of 10 years’ experience in the market in which the Building is located, and Tenant shall have 10 days after receiving such names to notify Landlord of which of the 3 brokers Tenant selects to determine the ROFO Rent. If Tenant fails to timely notify Landlord of Tenant’s selection, Landlord shall have the right to unilaterally appoint the broker. The fee and expenses of the broker shall be shared equally by Landlord and Xxxxxx. (e) Except to the extent expressly set forth in Landlord’s ROFO Notice to the contrary, if Tenant elects to lease the ROFO Space, such space shall become subject to this Lease upon the same terms and conditions as are then applicable to the original Premises, except that Tenant shall accept the ROFO Space in “AS IS” condition and Landlord shall have no obligation to make any improvements or alterations to the ROFO Space, and the term of Tenant’s lease of the ROFO Space shall be the term specified in Landlord’s ROFO Notice. Landlord shall determine the exact location of any demising walls (if any) for the ROFO Space. Tenant shall not be entitled to any tenant improvement allowances, free rent periods, or other special concessions granted to Tenant with respect to the original Premises. Upon Xxxxxx’s leasing of

45 the ROFO Space, the “Premises” shall include the ROFO Space and, except as otherwise set forth in this Section, all computations made under this Lease based upon or affected by the rentable area of the Premises shall be recomputed to include the ROFO Space. (f) If Tenant timely exercises its right to lease the ROFO Space: (i) Tenant’s lease of the ROFO Space shall commence upon the later of: (A) the date of availability specified in Landlord’s ROFO Notice; or (B) the date Landlord tenders possession of the ROFO Space in vacant condition; (ii) the ROFO shall thereafter be null and void; and (iii) upon Landlord’s request, Tenant shall execute an appropriate new lease or amendment, in form and content reasonably satisfactory to both Landlord and Tenant, memorializing the expansion of the Premises as set forth in this Section (provided Xxxxxx’s failure to execute such lease or amendment shall not negate the effectiveness of Tenant’s exercise of the ROFO).
