2.LEASING AGREEMENT.

2.1.Grant of Lease. Landlord, in consideration of the Fixed Basic Rent and any Additional Rent to be paid and the other covenants and agreements to be performed by Tenant pursuant to the provisions hereof, does hereby lease, demise and let unto Tenant the Premises located in the Office Unit commencing as of the Commencement Date and ending on the Expiration Date, unless sooner terminated as herein provided, together with certain rights to the Common Areas.

2.2.Term of Lease. The Term of this Lease and Tenant’s obligation to pay Fixed Basic Rent and Additional Rent hereunder shall commence on the Commencement Date. The Term of this Lease shall expire on the Expiration Date, unless earlier terminated as provided herein. After the commencement of the Term, Tenant and Landlord shall promptly execute a commencement date agreement setting forth the actual Commencement Date and Expiration Date in the form attached hereto as Exhibit E. The failure of either party to execute or deliver the commencement date agreement shall not in any way reduce or modify the respective obligations of Tenant and Landlord hereunder. In the event that the Tenant Improvements (as such term is defined in Section 21 hereof) are completed prior to the Commencement Date, Tenant shall be permitted to commence occupancy and business operations within the Premises upon the completion of the Tenant Improvements until the Commencement Date without any obligation to pay Rent during such period (the “Early Access Period”). All other terms of this Lease shall be applicable during the Early Access Period, and Tenant shall be responsible for the cost of services requested by Tenant (e.g., after hours HVAC service) plus the cost of electricity charges described on Exhibit B, attached hereto.

3.RENT.

3.1Fixed Basic Rent. Tenant shall pay to Landlord at the management office of the Building, or to such other person or such other place as directed from time to time by written notice to Tenant from Landlord or by method of electric funds transfer (EFT), without demand, notice, offset or deduction, the Fixed Basic Rent. Fixed Basic Rent shall be payable in equal monthly installments in advance on the first day of each calendar month during the Term without demand. Fixed Basic Rent shall be prorated for partial months within the Term.

3.2Rental Payments. All sums paid by Tenant hereunder shall be first credited to any Fixed Basic Rent due and then to any Additional Rent due (and allocated among any different items of Additional Rent as Landlord may determine). All payments of Rent shall be in lawful money of the United States of America. No acceptance by Landlord of a lesser sum than the Rent then due shall be deemed to be other than on account of the earliest amount of such Rent due. No endorsement or statement on any check or any letter accompanying any check or payment of Rent shall be deemed an accord and satisfaction or compromise and settlement, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such payments due or to pursue any other remedy as provided in this Lease.

3.3Partial Month. If the Term of this Lease begins or ends on a day other than the first or last day of a calendar month, respectively, Fixed Basic Rent payable on account of such calendar month shall be prorated (on the basis of the number of days during such calendar month that fall within the Term of this Lease and the actual number of days in such month) and, as to any partial month in which the Commencement Date occurs, shall be payable, in advance, on the Commencement Date.

3.4Operating Expenses. Commencing on the Commencement Date, Tenant shall pay electricity charges in accordance with Exhibit B. Commencing on January 1, 2024, Tenant shall pay to

Landlord, as Additional Rent, Tenant’s Proportionate Share of the amount by which Operating Expenses (defined on Exhibit B) for any year during the Term exceed the Operating Expenses for the Base Year (defined in Section 1.B), with such amount to be paid by Tenant in equal monthly installments pursuant to Landlord’s estimate, as further set forth on Exhibit B. To the extent applicable, Tenant’s Proportionate Share of Operating Expenses shall be reduced proportionately to correspond to the duration of periods less than a Calendar Year.

From the Commencement Date through Calendar Year 2024, Landlord shall use commercially reasonable efforts to efficiently manage Operating Expenses for the Office Unit, however, during such period there shall be no cap on any increase in Operating Expenses. Landlord agrees that commencing as of Calendar Year 2025 (the “Capped Costs Base Year”), Tenant’s obligation to pay Controllable Operating Expenses (as defined below) shall not increase by more than five percent (5.0%) of the Controllable Operating Expenses payable by Tenant during the immediately preceding Calendar Year, calculated on a cumulative basis throughout the Term. For all purposes under this Lease, the term “Controllable Operating Expenses” shall mean any Operating Expenses other than insurance, utilities, snow and ice removal, any amounts associated with the costs of capital improvements to be reimbursed by Tenant, and any and all other operating expenses that are not within the reasonable control of Landlord. Operating Expenses shall be determined on an aggregate and not on an individual basis and the cap on Operating Expenses shall be determined as those expenses have been adjusted for vacancy or usage pursuant to the terms of this Lease.

3.5Real Estate Taxes. Commencing on January 1 of the Calendar Year immediately following the Real Estate Taxes Base Year (defined below), Tenant shall pay Landlord, as Additional Rent, Tenant’s Proportionate Share of the amount, if any, by which Real Estate Taxes (defined on Exhibit B) for the applicable Calendar Year exceed the Real Estate Taxes for the Real Estate Taxes Base Year (such excess amounts hereinafter called “Increases in Real Estate Taxes”). The “Real Estate Taxes Base Year” shall mean the later to occur of (a) the first Calendar Year in which Allegheny County assesses the “Building Value” for the Office Unit after completion of the construction of the Office Unit and (b) the Calendar Year 2023. The parties acknowledge the existence of a Minimum Payment and Covenant Agreement, dated February 27, 2020 (“Minimum Payment Agreement”), which establishes that upon completion of the Development Project, as such term is defined therein, that the total minimum assessed value for the Building and the property located at 5700 Penn Avenue shall be not less than $52,625,571.00.

3.6Additional Amounts Due Hereunder. All sums payable by Tenant under this Lease, whether or not stated to be rent, Fixed Basic Rent or Additional Rent or otherwise denominated (hereinafter collectively referred to as “Rent”), shall be collectible by Landlord as rent and in the event of a default in payment thereof Landlord shall have the same rights and remedies as for a failure to pay Fixed Basic Rent (without prejudice to any other right or remedy available therefor).

3.6Late Charge. If Tenant shall fail to pay Fixed Basic Rent and all other sums, amounts, liabilities, and obligations which Tenant herein assumes or agrees to pay, whether designated as Rent, additional rent, costs, expenses, damages, losses or otherwise (collectively “Rent”), Tenant acknowledges that Landlord will incur costs not contemplated by this Lease, the exact amount of which is difficult to ascertain. Accordingly, and in satisfaction of such costs, if any installment of Rent or other sum shall not be received by Landlord within ten (10) days after due, Tenant shall pay a late charge equal to ten cents for every unpaid dollar thereof plus any reasonable attorney’s fees and costs incurred by Landlord by reason of Tenant’s failure to pay Rent when due, notwithstanding the date on which such payment is actually paid to Landlord. In addition to the Late Charge, all due and unpaid Rent that remains unpaid for a period of thirty (30) days after due shall, as of the thirty-first (31st) day begin accruing interest at a rate of twelve percent (12%) per annum, compounded monthly, until such Rent is paid, not to exceed the maximum nonusurious rate permitted by applicable law of the State or the United State of America, whichever shall permit the higher nonusurious rate, such interest being in addition to and cumulative of any other rights and

remedies which Landlord may have with regard to the failure of Tenant to make any such payments under this Lease. Any such late charge and interest, to the extent applicable, shall be due and payable at the time of actual payment of the Rent. Nothing contained in this Paragraph 3.6 is intended to grant Tenant any extension of time in respect of the due dates for any payments under this Lease, nor shall the same be construed to be a limitation of any other rights or remedies of Landlord under this Lease or otherwise.

3.7Independent Covenant; Survival. Tenant's covenant to pay all Rent hereunder is independent of any other covenant, agreement, term or condition of this Lease. Without limiting the other obligations of Tenant which shall survive the expiration of the Term, the obligation of Tenant to pay Rent accrued during the Term shall survive the expiration of the Term hereof.

4.UTILITIES AND SERVICES.

4.1.Landlord will furnish the following services to the Premises and the Common Area in a manner consistent with Class A office buildings in the Pittsburgh metropolitan area (i) electricity for normal lighting and ordinary office machines, (ii) during Building Hours, HVAC to provide a comfortable temperature for office business operations in accordance with Section 12 of Exhibit G of this Lease, (iii) janitorial service (as set forth in Exhibit D), (iv) cold and hot water for drinking and lavatory purposes, (v) elevator service, (vi) restroom supplies, (vii) exterior window cleaning, and (viii) maintenance of all paved surfaces and parking areas, including snow removal. In addition, Landlord shall provide Common Area lighting at the Property during Building Hours and for such additional hours as, in Landlord’s judgment, is necessary or desirable to ensure proper operation of the Property and is consistent with Class A buildings within the area.

4.2.Tenant will be entitled to make use of HVAC beyond the Building Hours, at Tenant’s sole cost and expense, provided Tenant has notified Landlord by 3:00 p.m. on the day that Tenant will require said overtime use if said overtime use is required on any weekday, and by 3:00 p.m. on Friday for Saturday and / or Sunday overtime use. Tenant will pay Landlord the HVAC After Hour Charge (as defined in Section 1.O) for HVAC beyond the Building Hours. The furnishing of the foregoing heating, air- conditioning and ventilation services during the times and in accordance with the standards hereinabove set forth shall be subject to any statute, ordinance, rule, regulation, resolution, or recommendation for energy conservation which may be promulgated by any governmental agency or organization which Landlord shall be required to abide.

4.3Except as provided in this Section 4.3, Landlord shall not be held liable for any damage or injury suffered by Tenant or by any of Tenant’s licensees, agents, invitees, servants, employees, contractors, or subcontractors or any other person or entity engaged, invited, or allowed to come onto the Premises by Tenant (herein collectively called “Tenant Parties”), resulting directly, indirectly, proximately, or remotely from the interruption of any service or utilities to the Premises or Building, including, but not limited to, temporary failure to supply any heating, air conditioning, electrical, water, or sewer services, or other utilities, or any of them nor shall such failure be construed as an eviction of Tenant. If (i) Landlord ceases to furnish any service in the Building as a result of a condition which affects only the Building (that is, which does not affect buildings in general in the vicinity of the Building), and (ii) such cessation is not caused by Force Majeure (defined below), and (iii) such cessation has not arisen as a result of an act or omission of Tenant or the Tenant Parties, and (iv) as a result of such cessation, the Premises (or a material portion thereof) is rendered untenantable and Tenant in fact ceases to occupy such space in the manner used prior to such cessation, and (v) such interruption to cessation of services occurs and continues for a period of not less than seven (7) consecutive business days, then, as Tenant’s sole and exclusive remedy for such cessation, the Fixed Basic Rent payable hereunder shall be equitably abated based on the percentage of the Premises so rendered untenantable and in fact not used by Tenant commencing as of the sixth (6th) consecutive business day after such interruption commenced. Such abatement shall begin retroactively

from the date of such cessation and continue until the date the Premises become tenantable again by the removal of such cessation of services.

4.4Tenant shall have access to the Premises 24 hours a day, 7 days a week. Landlord agrees that access to the Premises, including, without limitation, access to the Building’s stairwells, elevators, fitness center and other Common Areas shall be provided by Landlord using a security access card/fob system that, as of the Commencement Date, is compatible with Tenant’s existing standard 26-bit HID proximity cards. Landlord shall provide Tenant (at Landlord’s cost) with access cards/fobs for access to the Building for each Tenant employee who will work in the Premises. The first one-hundred access cards/fobs shall be provided to Tenant at no cost. Any additional access cards/fobs or any access cards/fobs that are lost or need to be replaced shall be provided or replaced by Landlord and Tenant shall reimburse Landlord for the cost of same. Security system access card panels shall be installed (a) at the Building entrance to the main lobby, (b) at the ground-level entrance to Stair 4 (located on S. Euclid Avenue) and

(c) at the entrance from the stairwell to the terrace on the second floor, by Landlord at Landlord’s expense, prior to the Commencement Date. An additional card readers and security systems specific to Tenant’s Premises, including, but not limited to, card readers from any emergency stairwells shall be installed by Tenant at Tenant’s expense, as part of the Tenant Improvements.

4.5Landlord covenants and agrees to make the planned fitness center in the Building (the “Fitness Center”), available as of the Commencement Date and during the Term for non-exclusive use by Tenant and its employees as part of the Common Areas, subject to each of Tenant’s employees executing a standard waiver of liability and license agreement form used for the fitness center. For the avoidance of doubt, any Tenant employee may use the facility regardless of whether the employee’s primary workplace is the Premises. Landlord shall keep the Fitness Center in good operating condition, commensurate with the condition of similar fitness centers in similar buildings in the market in which the Building is located. Tenant’s employees, licensees and invitees shall have access to the Fitness Center during the Building Hours throughout the Term. The use of the Fitness Center shall be subject to the rules and regulations (including rules regarding hours of use) established from time to time by the Landlord. Landlord and Tenant acknowledge that the use of the Fitness Center by the employees shall be at their own risk. Notwithstanding the foregoing in this Section 4.5, Landlord may temporarily close or suspend access to and use of the Fitness Center for a reasonable time for the replacement, remodeling or relocation of the Fitness Center. Any such temporary closure shall not entitle Tenant to an abatement or reduction in Rent, constitute a constructive eviction, or result in an event of default by Landlord under this Lease. Tenant hereby voluntarily releases, discharges, waives and relinquishes any and all actions or causes of action for personal injury or property damage occurring to Tenant or its employees or agents arising as a result of the use of the fitness center, or any activities incidental thereto, wherever or however the same may occur, and further agrees that Tenant will not prosecute any claim for personal injury or property damage against Landlord or any of its officers, agents, servants or employees for any said causes of action. Tenant’s rights hereunder to permit its employees to use the Fitness Center shall belong solely to Tenant and may not be transferred or assigned.

4.6Landlord covenants and agrees to make available to the Office Unit tenants the following amenities during the Term: a bike storage room, building security systems, and loading docks. Landlord reserves and retains all rights to replace, remodel, and relocate, as applicable, any of the foregoing Office Unit amenities and to temporary suspend the use of the same.

5.MORTGAGE BY LANDLORD. This Lease and Tenant’s interest hereunder shall at all times be subject and subordinate to the lien and security title of any deeds to secure debt, deeds of trust, mortgages, ground or underlying leases, or other interests heretofore or hereafter granted by Landlord or which otherwise encumber or affect the Property and to any and all advances to be made thereunder and to all renewals, modifications, consolidations, replacements, substitutions, and extensions thereof (each of which

is herein called a “Mortgage”), provided the Mortgagee (defined below) recognizes the validity of this Lease and the Mortgagee agrees that, and by having the Lease be so subordinate such party is deemed to have agreed that, notwithstanding any default by Landlord with respect to said ground lease or mortgage or any termination or foreclosure thereof, Tenant’s possession and right of use under this Lease and the rights of Tenant under this Lease in and to the Premises shall not be disturbed by such Mortgagee unless and until an event of Default shall have occurred hereunder and is continuing. This clause shall be self-operative and no further instrument of subordination need be required by any holder of any Mortgage. Notwithstanding the foregoing, upon request from a Mortgagee, subject to Tenant’s receipt of a subordination and non-disturbance agreement from any such Mortgagee on such Mortgagee’s then current form which may be revised to incorporate commercially reasonable changes requested by Tenant and approved by such Mortgagee, Tenant shall execute a commercially reasonable subordination, non- disturbance and attornment agreement in favor of the Mortgagee. In lieu of having the Mortgage be superior to this Lease, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease.

Tenant shall, from time to time upon not less than fifteen (15) days’ prior request by Landlord, deliver to Landlord an estoppel certificate, in form satisfactory to Landlord and subject to Tenant’s commercially reasonable modification, in writing and certifying: (i) that this Lease is unmodified and in full force and effect (or, if there have been modifications that the Lease as modified is in full force and effect); (ii) the dates to which Rent and other charges have been paid; (iii) that Landlord is not in default under any provision of this Lease, or, if in default, the nature thereof in detail, and (iv) such other matters as may be reasonably requested, it being intended that any such statement may be relied upon by any prospective purchaser or tenant of the Office Unit, any mortgagees or prospective mortgagees thereof; or any prospective assignee of any mortgage thereof. In the event Tenant fails to deliver the estoppel certificate within such fifteen (15) days after demand in writing, Tenant shall be deemed to have accepted and executed such estoppel letter and other documents and hereby authorizes Landlord as its attorney-in- fact for the sole purpose of executing such estoppel certificate.

6.CERTAIN RIGHTS RESERVED TO LANDLORD. Landlord reserves the following rights:

(a)Entry – if Tenant abandons the Premises and fails to pay Rent in accordance with the terms set forth herein beyond any applicable notice and cure period, to enter the Premises in order to decorate, remodel, repair, alter or otherwise prepare the Premises for re-occupancy, without same being deemed acceptance of a surrender and without affecting Tenant’s obligations to pay Rent.

(b)Access to Premises – Landlord and its employees, servants and agents shall have the right, upon 24 hours’ prior notice, to enter the Premises during business hours, or at such other reasonable times for the purpose of examining or inspecting the Premises to ensure that Tenant is complying with all of its obligations hereunder, showing the same to prospective purchasers, mortgagees, or tenants of the Office Unit, performing janitorial, cleaning, maintenance and repair services, including, but not limited to regular HVAC service repairs, maintenance, and replacement, and making such alterations, repairs, improvements or additions to the Premises or other portions of the Property as Landlord may deem necessary or desirable. Notwithstanding the foregoing, prior to Landlord's entry into the Premises other than in an emergency or for purposes of performing Landlord's normal janitorial, cleaning, maintenance and repair services contemplated under this Lease (for which entry no advance notice shall be required), Landlord shall provide at least twenty-four (24) hours prior notice to Tenant (which notice need not be in writing). In connection with any such entry, Landlord shall be allowed to take all material into and upon the Premises that may be required therefor without the same constituting an eviction of Tenant in whole or in part, and the Rent shall not abate while said alterations, repairs, improvements or additions are being made by reason of loss or interruption of business of Tenant or otherwise. If representatives of Tenant shall not be present to open and permit entry into the Premises at any time when such entry by Landlord is necessary or permitted

hereunder, Landlord may enter by means of a master key (or forcibly in the event of an emergency) without liability to Tenant and without such entry constituting an eviction of Tenant or termination of this Lease.

(c)Building and Property Identification and Appearance – to change the Building’s, Office Unit’s, and/or Property’s name or street address; to install and maintain all signs on the exterior or interior of the Building and/or Property, to approve prior to installation, all signs, shades, blinds, drapes and internal lighting; and to change the arrangement of entrances, doors, corridors, stairs and other public service portions of the Office Unit and/or Property, provided that such changes do not materially and adversely interfere with Tenant’s reasonable access to the Premises or to the Office Unit.

Landlord may enter upon the Premises and may exercise any or all of the foregoing rights hereby reserved without being liable in any manner to Tenant. Any such entry and/or exercise of rights shall not in any way affect the obligations of Tenant under this Lease, including without limitation, the obligation to pay Rent.

7.INSURANCE AND INDEMNIFICATION.

7.1.(1) Tenant shall obtain and keep in full force during its occupancy of the Premises and during the entire Term of this Lease, at its sole cost and expense, a commercial general liability policy of insurance with coverages reasonably acceptable to Landlord, in Landlord's sole discretion, which by way of example and not limitation, protects Tenant and Landlord (as an additional insured) against claims for bodily injury, personal injury and property damage based upon, involving or arising out of Tenant’s use, occupancy or maintenance of the Premises and all areas appurtenant thereto. Such insurance shall be on an occurrence basis providing single limit coverage in an amount not less than One Million Dollars ($1,000,000.00) per occurrence and Three Million Dollars ($3,000,000.00) in the aggregate for personal injury, bodily injury, death, disease and damage or injury to or destruction of property (including the loss of use thereof) occurring upon, in, or about the Premises, and a policy of supplemental "umbrella" liability insurance following the form of the primary liability policy required hereunder and having a limit of not less than Five Million Dollars ($5,000,000.00). The policy shall not contain any intra-insured exclusions as between insured persons or organizations but shall include coverage for liability assumed under this Lease as an "insured contract" for the performance of Tenant's indemnity obligations under this Lease.

(2)Tenant shall obtain and keep in force during the Term of this Lease “Causes of Loss- Special Form” property insurance. Said insurance shall be written on a one hundred percent (100%) replacement cost basis on Tenant's personal property, all tenant improvements installed at the Premises, Tenant's trade fixtures, and other property. By way of example and not limitation, such policies shall provide protection against any peril included within the classification “fire and extended coverage”, against vandalism and malicious mischief, theft, sprinkler leakage, earthquake damage and flood damage. If this Lease is terminated as the result of a casualty, the proceeds of said insurance, if any, attributable to the replacement of all tenant improvements at the Premises paid for by Landlord and all rental concessions shall be paid to Landlord.

(3)Tenant shall, at all times during the Term hereof, maintain in effect workers' compensation insurance as required by applicable law and insurance reasonably satisfactory to Landlord. In addition, in the event that Tenant operates or parks any Tenant-owned vehicles at the Property during the Term of this Lease, Tenant shall maintain in effect during the Term hereof a policy of automobile liability insurance with bodily injury limits of $500,000 per person, $1,000,000 per accident, and $100,000 per accident for property damage.

(4)Prior to the Commencement Date, Tenant shall deliver certificates evidencing the insurance policies to Landlord. Certificates evidencing renewals shall be delivered to Landlord no later

than fifteen (15) days after each renewal, as often as renewal occurs, and in no event less than fifteen (15) days prior to the date on which the policy would otherwise expire. Tenant shall use commercially reasonable efforts to request and obtain from its insurance carriers insurance policies that require the insurer to notify Landlord in writing thirty (30) days prior to any cancellation. The inability of Tenant to obtain an insurer’s consent to delivery such notice to Landlord after reasonable efforts shall not constitute a default hereunder. Notwithstanding the foregoing, Tenant shall promptly deliver notice to Landlord upon Tenant’s receipt any notice of cancellation issued by any of Tenant’s insurers providing the coverages required under this Lease.

(5)In the event Tenant fails to furnish such insurance, Landlord may obtain such insurance and the premiums shall be paid by Tenant to Landlord upon demand. The minimum limits of the aforesaid insurance shall be subject to increase at the end of every three (3) years during the Term if Landlord, in the exercise of its reasonable judgment, shall deem it necessary for adequate protection.

7.2Landlord makes no representation to Tenant that the limits or forms of coverage specified above or approved by Landlord are adequate to insure Tenant's property or Tenant's obligations under this Lease, and the limits of any insurance carried by Tenant shall not limit Tenant’s obligations or liability under any indemnity provision included in this Lease or under any other provision of this Lease.

7.3All insurance policies obtained by Tenant pursuant to this Section 7 shall be in form and substance reasonably satisfactory to Landlord and shall be issued by companies qualified to do business in the Commonwealth of Pennsylvania that have ratings of not less than "A-" and of not less than "Class XI" in financial size in the most current available A.M. Best's Insurance Reports. Such policies (exclusive of the worker's compensation policy) shall name Landlord, Manager and such other parties as Landlord shall specify as additional insureds to the extent of the liabilities for third party bodily injury and property damage assumed by Tenant under this Lease and shall further specify that Landlord shall receive thirty (30) days prior written notice of any proposed cancellation, non-renewal of or material change in any such policy. Certificates of all policies of insurance obtained by Tenant hereunder shall be provided to Landlord prior to Tenant's entry upon the Premises, and thereafter at least thirty (30) days prior to the scheduled expiration date of each such policy, evidencing Tenant's renewal or replacement thereof.

7.4All policies of insurance carried or required to be carried by either party hereunder shall include a waiver of subrogation endorsement, containing a waiver by the insurer of all right of subrogation against the other party in connection with any loss, injury or damage thereby insured against. The waiver of subrogation shall apply regardless of any deductible (or self-insured retention) or self-insurance carried by either party. Any additional premium for such waiver shall be paid by the primary insured. To the full extent permitted by law, Landlord and Tenant each waive all rights of recovery against the other (and any officers, directors, partners, employees, agents and representatives of the other), and agree to release the other from liability, for loss or damage to the extent such loss or damage is covered by valid and collectible insurance in effect covering the party seeking recovery at the time of such loss or damage or would be covered by the insurance required to be maintained under this Lease by the party seeking recovery. If the release of either party, as set forth above, should contravene any law with respect to exculpatory agreements, the liability of the party in question shall be deemed not released but shall be secondary to the liability of the other’s insurer. Written notice of the terms of such mutual waivers of subrogation shall be given to each insurance carrier and said insurance policies shall be properly endorsed, if necessary, to prevent the invalidation of said insurance coverages by reason of said waivers.

7.5Tenant will indemnify, save harmless, and defend Landlord from and against any and all claims and demands in connection with any accident, injury or damage whatsoever caused to any person or property arising directly or indirectly out of the operation of Tenant’s business in the Premises or any part thereof, or arising directly or indirectly from any act or omission of Tenant or any party acting under the direction or under the control of Tenant, and from and against any and all cost, expenses and liability,

including reasonable attorneys' fees, incurred in connection with any such claim or proceeding brought thereon, except to the extent the same arises from the negligence or willful misconduct of Landlord. Landlord shall indemnify, save harmless and defend Tenant from and against any and all claims and demands in connection with any accident, injury or damage whatsoever caused to any person or property, including reasonable attorneys’ fees, arising out of the negligence or willful misconduct of Landlord, to the extent of proceeds of insurance actually received by Landlord. The indemnity obligations in this Section

7.5shall survive any expiration or termination of this Lease.

7.6If any insurance policy upon the Premises or the Office Unit or any part thereof shall be canceled or shall be threatened by the insurer to be canceled, the coverage thereunder reduced or threatened to be reduced, or the premium therefor increased or threatened to be increased in any way by the insurer by reason of the use and occupation of the Premises by Tenant or by any assignee or subtenant of Tenant and if Tenant fails to remedy the condition giving rise to the cancellation, reduction, or premium increase or threat thereof within ten (10) business days after notice thereof by Landlord, Landlord may, at its option, do any one of the following:

(i)Enter upon the Premises and remedy the condition giving rise to the cancellation, reduction, or premium increase or threat thereof, and in such event, Tenant shall forthwith pay the cost thereof to Landlord as additional rent; and if Tenant fails to pay such cost, Landlord may declare a default by Tenant and thereupon the provisions of Sections 15 and 16 shall apply, and Landlord shall not be liable for any damage or injury caused to any property of Tenant or of others located on the Premises as a result of the entry; or

(ii)If the sole action taken by the insurer is to raise the premium or other monetary cost of the insurance, demand payment from Tenant of the premium or other cost as additional rent hereunder, and if Tenant fails to pay the increase to Landlord within ten (10) days of demand by Landlord, Landlord may declare a default by Tenant and thereupon the provisions of Sections 15 and 16 shall apply. Tenant acknowledges that it has no right to receive any proceeds from any insurance policies carried by Landlord and that such insurance will be for the sole benefit of Landlord with no coverage for Tenant for any risk insured against.

7.7From and after the date of this Lease, Landlord will obtain and keep in full force during the entire Term of this Lease (a) a commercial general liability policy of insurance with coverage against claims for personal injury, death and property damage occurring in or about the Property, which coverage shall afford protection with limits of not less than Five Million Dollars ($5,000,000.00) in the aggregate, and (b) a policy or policies of all risks extended coverage insurance covering the Property endorsed to provide full replacement cost coverage and providing protection against perils included within the standard Pennsylvania form of fire and extended coverage insurance policy, together with insurance against sprinkler damage, vandalism, malicious mischief and such other risks as Landlord may from time to time reasonably determine consistent with relevant industry standards and with any such deductibles as Landlord may from time to time reasonably determine consistent with relevant industry standards. For the purposes of this Section 7.7, Landlord may provide coverage under an umbrella policy providing the minimums set forth above to satisfy the insurance obligations herein.

8.CASUALTY.

8.1Should the Premises (or any part thereof) be damaged or destroyed by fire or other casualty insured under Landlord's standard fire and casualty insurance policy with approved standard extended coverage endorsement applicable to the Premises, Landlord shall, except as otherwise provided herein, repair and/or rebuild the Premises to the same condition as existed on the Commencement Date with reasonable diligence, commencing the work within 90 days after such damage (subject to delays in the

adjustment of insurance). Landlord shall promptly and diligently seek adjustment of insurance proceeds after any casualty. Landlord's obligation hereunder shall be limited to the Office Unit and improvements originally provided by Landlord at the Commencement Date of the Term, the net proceeds of insurance recovered for the casualty damage, and shall be subject to zoning and building laws or ordinances then in existence. If there should be interference with the operation of Tenant's business in the Premises as a result of such damage or destruction which requires Tenant as a result of such damage or destruction to temporarily close its business, the Fixed Basic Rent and Additional Rent shall abate in proportion to the square footage of the Premises that Tenant is unable to utilize as a result of the casualty, for the period commencing with the damage and ending upon Landlord’s completion of its restoration work, or at such earlier date as Tenant is able to resume use the entire Premises. Unless this Lease is terminated by Landlord as hereinafter provided, Tenant shall, at its cost and expense, repair, restore, redecorate and re-fixture the Premises and restock the contents thereof in a manner and to at least a condition equal to that existing prior to such damage or destruction except for the Office Unit and improvements to be reconstructed by Landlord as above set forth, and the proceeds of all insurance carried by Tenant on the property, decorations and improvements, as well as fixtures and contents in the Premises, shall be held in trust by Tenant for such purposes. Tenant agrees to commence such work within ten (10) days after the date of such damage or destruction or the date Landlord substantially completes any reconstruction required to be completed by it pursuant to the above, whichever date is later, and Tenant shall diligently pursue such work to its completion.

8.2Notwithstanding anything to the contrary contained in the preceding Paragraph 8.1 or elsewhere in this Lease, Landlord may terminate this Lease on thirty (30) days’ notice to Tenant, given within ninety (90) days after the occurrence of any damage or destruction if: (1) the Premises are damaged or destroyed as a result of a risk which is not covered by Landlord's insurance, (2) the Premises are damaged and the cost to repair the same shall be more than twenty-five percent (25%) of the cost of replacement thereof, (3) the Premises are damaged during the last two (2) years of the Term, (4) if the Office Unit is damaged (whether or not the Premises are damaged) to such an extent that, in the sole judgment of Landlord, the Office Unit cannot be operated as an integral unit, (5) if available insurance proceeds for the Office Unit are insufficient to repair or rebuild the damage, (6) if any mortgagee shall not permit the applicable of adequate insurance proceeds for repair or restoration, or (7) if the casualty results in damage to the Premises which Landlord reasonably estimates will take in excess of 12 months after the beginning of restoration to restore the Premises to the same condition as existed on the Commencement Date. Tenant may terminate this Lease, upon thirty (30) days prior written notice to Landlord given within ninety (90) days after the occurrence of any casualty event if: (i) the Premises are damaged or destroyed and Landlord’s estimate of time to complete repairs (given within sixty (60) days after such casualty) is greater than two hundred seventy (270) days, or (ii) the Premises or Office Unit is damaged within the last twelve (12) months of the Term.

8.3Tenant agrees that Landlord's obligation to restore, and the rental abatement provided in this Article, shall be Tenant's sole recourse against Landlord in the event of casualty damage to the Premises, and Tenant waives any other rights Tenant may have under any applicable law or any other Article of this Lease to terminate this Lease or seek damages against Landlord by reason of casualty damage to the Premises or the Office Unit. This Article represents the entire agreement between the parties respecting casualty damage to the Premises or the Office Unit.

9.SURRENDER OF PREMISES. Tenant shall deliver the Premises (together with all Tenant Improvements, alterations and other improvements made by or on behalf of Tenant) to Landlord upon the expiration or sooner termination of the Term or upon termination of Tenant's right of possession of the Premises in good condition, less ordinary wear and tear, or damage from casualty, excepted, failing which Landlord may restore the Premises to such condition and Tenant shall pay Landlord the cost thereof upon demand. All installations (including low voltage cabling), alterations, additions, hardware, non-trade

fixtures and improvements, temporary or permanent, except movable furniture, trade fixtures and equipment belonging to Tenant (“Fixtures”), in or upon the Premises, whether placed there by Tenant or Landlord, shall be Landlord's property and shall be relinquished to Landlord in good condition, ordinary wear and tear excepted, at the termination of this Lease or Tenant's right to possession by lapse of time or otherwise, all without compensation, allowance or credit to Tenant. At the time of approving alterations in accordance with Section 10 or the Tenant Improvements Work in Section 21, Landlord may identify in writing to Tenant that such alterations must be removed or restored at the end of the term. Tenant shall otherwise have no obligation to remove the Tenant Improvements or any alterations or improvements under this Section 9 that have been approved by Landlord in writing pursuant to Section 10 unless identified by Landlord in accordance with the immediately preceding sentence. If Tenant fails to comply with the provision of this paragraph, all personal property and equipment of Tenant shall be deemed abandoned and Landlord may remove the same upon two (2) business days’ notice and Tenant shall, upon demand, pay to Landlord the cost of such removal and of any necessary restoration of the Premises.

Landlord shall either approve or make reasonable detailed comments on any plans and specifications within ten (10) days after delivery of such plans and specifications to Landlord, or within twenty (20) business days of Tenant’s delivery of such plans and specifications if the alteration, addition or improvement will impact the structural components or mechanical systems of the Office Unit. Landlord reserves the right to require Tenant to utilize certain subcontractors for the performance of alterations that may impact, modify, or otherwise affect the operation of the Office Unit’s systems or that may void or otherwise impact any applicable warranty.

In the event that Landlord approves a request for alteration, such approval shall not constitute a representation or warranty of Landlord as to the adequacy or sufficiency of such drawings, plans and specifications, or alterations, improvements, modifications or additions to which they relate, for any use, purpose or conditions, or that the same is acceptable for any governmental approvals or permits, or with respect to the design and engineering of any such work, but such approval shall merely be the consent of Landlord for Tenant to complete the proposed alterations. Notwithstanding anything to the contrary in this Lease, this Section 10 shall not apply to the initial Tenant Improvements outlined in Section 21. Upon completion of any alterations within the Premises, Tenant shall furnish to Landlord a full size original of all plans, all electronic files, and all CADD files, as may be applicable.

To the extent that Tenant desires to complete any alterations in accordance with US Green Building Council’s (“USGBC”) standards and objectives, Tenant may utilize the performance standards set forth for commercial interiors LEED CI rating system to certify the alterations with the USGBC. Landlord makes no representations or warranties that any or all alterations will be certified and Tenant should coordinate with USGBC prior to commencing any such alterations.

Tenant agrees to repair immediately any damage to the Property caused by, or in connection with, the removal of any articles of personal property, business or trade fixtures, alterations, improvements and installations, including, without limitation thereto, repairing the floor and patching and painting the walls where required by Landlord, to Landlord's satisfaction.

10.4All alterations, additions, or improvements made, installed in, or attached to the Premises by Tenant, upon the consent specified above, shall be made at Tenant’s expense at Tenant’s sole risk and in a good and workmanlike manner with labor and materials of such quality as Landlord may reasonably require (it being understood that materials equal to or better than those that are then existing shall be considered acceptable), strictly in accordance with the plans and specifications approved by Landlord, all applicable codes, laws, ordinances, regulations, and other requirements of any appropriate governmental authority, and any applicable covenants or other restrictions, and prosecuted diligently and continuously to completion so as to minimize interference with the normal business operations of other tenants in the Office Unit, the performance of Landlord’s obligations under this Lease and any work being done by contractors engaged by Landlord with respect to or in connection with the Office Unit.

10.5Other than as related to the initial buildout for Tenant, Tenant agrees to reimburse Landlord a reasonable fee equal to the costs incurred or otherwise invoiced to Landlord by Landlord’s consultants for examination and approval of any architectural or engineering plans and specifications, which shall be payable as Additional Rent within thirty (30) days after demand.

10.6Upon completing any such work that exceeds $100,000.00 in costs, Tenant shall furnish Landlord with contractors' affidavits and full and final waivers of lien and receipted bills covering all labor and materials expended and used. Tenant shall obtain valid and effective lien waiver(s) from each sub- contractor, contractor, and material provider in exchange for all payments made to such sub-contractor, contractor, and material provider for any such work or materials, however, copies of paid invoices may be provided in lieu of lien waivers for material suppliers.

Landlord shall keep the roof, roof membrane, foundation, exterior walls, windows, window seals, Common Areas, electrical systems, HVAC systems, plumbing systems, fire suppression systems, fire alarm systems and all common sewer and utility lines located outside the Premises, in good order and repair consistent with Class A buildings in the Pittsburgh metropolitan area and in compliance with all applicable laws, and in a tenantable, safe condition. Landlord shall be responsible for the repair, maintenance, and replacement of light bulbs and lighting fixtures located within the Premises, with such costs and expenses being the responsibility of Tenant. Landlord shall have no obligation to maintain, replace, or repair any other improvements located within the Premises, the maintenance of which is and shall be the responsibility of Tenant. Notwithstanding the obligation of Landlord under this Section 11.1, Tenant shall be responsible for the cost of any and all damage and / or repairs arising from the negligence or willful misconduct of Tenant or any of the Tenant Parties. Landlord shall have no obligation to make any repairs unless and until Tenant notifies Landlord in writing of the necessity thereof, in which event Landlord shall have reasonable time in which to make such repairs; however, Tenant may notify Landlord verbally of any emergency repairs or any minor, routine or day-to-day repairs which need to be made.

Landlord covenants to use commercially reasonable efforts to implement repairs, alterations, additions or improvements (including, without limitation, any work related to the initial construction of the Building) in a timely and expeditious manner and covenants to take reasonable steps to minimize disruption and interference with Tenant’s operations in the Premises. Provided Landlord reasonably complies with the preceding sentence, Landlord shall not be liable by reason of any inconvenience, injury to, or interference with Tenant's business arising from the making of any repairs, alterations, additions or improvements in or to the Premises or the Property and Office Unit or to any appurtenances or equipment therein. Prior to commencing any such repairs, alterations, additions, or improvements that are reasonably anticipated to be disruptive to Tenant’s business operations within the Premises, Landlord will provide Tenant with notice prior to commencement of such work. No prior notice shall be required for any repairs completed during an ongoing emergency. There shall be no abatement of Rent because of such repairs, alterations, additions, or improvements except as specifically set forth in Section 8 of this Lease. To the extent requested by Tenant and subject to scheduling limitations, Landlord shall use commercially reasonable efforts, at Tenant’s expense, to perform such work at times other than during the normal Business Hours if reasonably required to avoid disruption to Tenant’s business operations in the Premises. Tenant shall pay any additional costs incurred for the completion of any such maintenance or repairs after normal Building Hours as Additional Rent hereunder.

13.ASSIGNMENT AND SUBLETTING.

13.1. Tenant, for itself, its heirs, distributees, executors, administrators, legal representatives, successors and assigns, expressly covenants that it shall not, voluntarily, involuntarily, by operation of law or otherwise, without Landlord's prior written consent (a) assign, convey, mortgage, pledge, encumber, hypothecate, or otherwise transfer this Lease or any interest therein; (b) allow any lien upon Tenant's interest; (c) sublet the Premises or any part thereof; (d) permit the use or occupancy of the Premises or any part thereof by anyone other than Tenant; or (e) grant any concession or license within the Premises. Tenant shall, by written notice, advise Landlord of any proposed assignment or subletting which notice shall state the name and address of the proposed assignee or subtenant, a summary of the terms of such subletting or assignment, including without limitation, all rent and/or other consideration payable thereunder or in connection therewith, and the effective date of such assignment or subletting (which shall be not less than thirty (30) days from the date such notice is given) (the “Tenant Notice”), and, concurrently with such Tenant Notice, Tenant shall deliver to Landlord a complete, unexecuted copy of the proposed sublease or assignment, all other documents and instruments related thereto and the proposed assignee's or subtenant's most recent financial statements for the past twelve (12) month period. Landlord shall have the right to make such investigations as it deems reasonable and necessary in determining the acceptability of the proposed assignee or subtenant. In the case of a sublease only, Landlord, at its election, shall have the right to be exercised by notice to Tenant given within ten (10) days after Landlord's receipt of Tenant's Notice, to terminate this Lease with respect to the space therein described as of the date stated in Tenant's Notice. If Tenant's Notice shall cover all of the Premises, and Landlord shall give the aforesaid termination notice, the Term of this Lease shall expire and end on the date stated in Tenant's notice as the effective date of subletting as fully and completely as if that date had been herein definitely fixed for the expiration of the Term. If, however, this Lease shall be terminated by Landlord pursuant to the foregoing with respect to less than the entire Premises, the Rent herein reserved shall be adjusted on the basis of the number of square feet of rentable area retained by Tenant in proportion to the number of square feet of rentable area in the entire Premises, and this Lease, as so amended, shall continue thereafter in full force and effect. If Landlord shall terminate this Lease in whole or in part as aforesaid, Landlord shall be free to deal directly with any such proposed subtenant without any responsibility or liability to Tenant on account thereof. Upon Landlord’s consent to any assignment or sublease, prior to the assignee’s or subtenant’s occupancy of the Premises, Tenant shall deliver to Landlord a true and complete copy of the executed sublease or assignment and all other documents and instruments related thereto.

13.2Landlord, upon receiving the Tenant Notice with respect to any such space, will not unreasonably withhold its consent to Tenant's assigning or subletting the space covered by the Tenant Notice and shall provide its consent or denial within ten (10) business days thereafter (Landlord’s failure to provide a response shall be deemed to be a denial of such request). Tenant agrees that any such assignment or sublease shall be subject to the following: (i) at the time thereof Tenant is not in default under

this Lease beyond any notice and cure provision; (ii) Landlord, in its sole discretion reasonably exercised, determines that the business and proposed use of the Premises of the proposed subtenant or occupant, as the case may be, are consistent with the Permitted Use described in this Lease; (iii) any assignee or subtenant shall expressly assume all the obligations of this Lease on Tenant's part to be performed; (iv) such consent, if given, shall not release Tenant of any of its obligations or liabilities whether past, present, or future (including, without limitation, its obligation to pay Rent) under this Lease; (v) Tenant agrees specifically to pay over to Landlord, as Additional Rent, all sums received by Tenant under the terms and conditions to such assignment or sublease which are in excess of the amounts otherwise required to be paid pursuant to this Lease, including, but not limited to, all other consideration, payments for furniture, fixtures, or equipment, and all other consideration of any form, type, or substance; (vi) a consent to one assignment, subletting, occupation or use shall be limited to such particular assignment, sublease, or occupation and shall not be deemed to constitute Landlord's consent to an assignment or sublease to or occupation by another person or entity; (vii) the liability of Tenant and each assignee will be joint, several, and primary for the observance of all the provisions, obligations and undertaking of this Lease, including the payment of Fixed Basic Rent and Additional Rent through the entire Term as the same may be renewed, extended, or otherwise modified, (viii) not in violation of any exclusive use restrictions in any occupancy or other agreement for space within the Office Unit, and (ix) Tenant will pay Landlord a reasonable administrative fee not to exceed $1,500.00 for fees incurred with respect to each request for consent, payable as Additional Rent. Any such assignment or subletting without such consent shall be void.

13.3Excepting any Permitted Transfer (defined below), in the event of a full assignment or sublease of this Lease through the end of the Term, any option or similar right of Tenant hereunder, including without limitation, any option to extend or renew, option to expand, first offer or first refusal right, or first right to lease, and all exterior signage rights are terminated; all options granted to Tenant hereunder upon the execution of the assignment or sublease shall henceforth become null and void and Tenant shall have no further rights thereto or therein.

13.4Notwithstanding anything contained in this Lease to the contrary, Tenant may assign this Lease or sublet all or any portion of the Premises (without Landlord’s prior written consent, but upon written notice to Landlord within five (5) days of any such assignment or sublease) to (i) any corporation or other entity directly or indirectly controlling or controlled by Tenant or under common control with Tenant, or

(ii) any successor by merger, consolidation, corporate reorganization or acquisition of all or substantially all of the assets of Tenant (any transaction referred to in clauses (i) or (ii) hereof will be a “Permitted Transfer”) provided that the net worth of any transferee of a Permitted Transfer will not be less than the greater of (A) the net worth of Tenant immediately preceding the Permitted Transfer or (B) the net worth of Tenant as of the date of the execution and delivery of this Lease by both parties. Any other assignment or subleasing of Tenant’s interest under this Lease will be subject to Landlord’s approval, which approval will not be unreasonably, withheld, conditioned or delayed. To the extent requested by Landlord, Tenant and any assignee or sublease shall execute a written agreement evidencing such assignment or sublease.

13.5In addition to any other grounds for denial, Tenant agrees that it shall be reasonable for Landlord to withhold Landlord’s consent to a proposed assignment or sublease (except as otherwise provided in subparagraph 13.4 above) if, in Landlord’s good faith judgment:

(a)the proposed assignee or subtenant does not have the financial strength to perform its obligations under this Lease or any proposed sublease;

(b)the proposed assignee or subtenant is a business competitor of Landlord or Manager, or is an affiliate of a business competitor of Landlord or Manager;

(c)the proposed assignee or subtenant intends to use any part of the Premises for a purpose not permitted under this Lease, for a use that Landlord considers to be inconsistent with the quality of the Office Unit or with other uses in the Office Unit, or in conflict with any exclusive uses then granted to other tenants of the Office Unit, or for a use entailing the use, storage, generation or transport of Hazardous Materials within the Office Unit; or

(d)a prospective tenant to whom Landlord has shown space in the Office Unit, and with whom Landlord has proposed possible lease terms, within the six (6) months preceding Landlord’s receipt of the Tenant Notice and, in any of such events, at the time of Landlord's receipt of the Tenant's Notice for consent hereunder any portion of the Office Unit is not fully leased to other tenants and Landlord is able to meet the square footage requirements of Tenant's proposed assignee or subtenant by leasing to such person or entity available space in the Office Unit that is reasonably comparable to the Premises (or the portion thereof proposed to be occupied by such person or entity).

14.HOLDING OVER. If Tenant retains possession of the Premises, or any part thereof, after the expiration or earlier termination of this Lease, Tenant shall pay Fixed Basic Rent at an annual rate equal to 150% of the Fixed Basic Rent payable for the last month of the Term immediately preceding said holdover computed on a per month basis and 100% of Additional Rent, and any damages sustained by Landlord as a result of such holdover. If any holdover in any portion of the Premises continues for a period exceeding thirty (30) days after delivery by Landlord of a written notice to vacate, then Tenant shall also be liable for any and all damages incurred by Landlord as a result of such holding over. The provisions of this Paragraph do not waive the Landlord’s right of re-entry or any other right hereunder that may be awarded by a court of law, and Landlord’s acceptance of Rent after expiration of the Term or earlier termination of this Lease shall not constitute consent to a holdover or result in a renewal. Nothing contained herein shall be construed to constitute Landlord’s consent to Tenant holding over after the expiration or earlier termination of the Term.

15.2A failure by Tenant to observe and perform any other provision or covenant of this Lease to be observed or performed by Tenant, where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant, provided, however, that if the nature of the default is such that the same cannot reasonably be cured within such thirty (30) day period, Tenant shall not be deemed to be in default if Tenant shall within such period commence such cure and thereafter diligently prosecutes the same to completion (not to exceed ninety (90) days in the aggregate);

(ii)Terminate Tenant’s right to possession but not the Lease and/or proceed in accordance with any and all provisions of Section 16.2 below.

16.2.Landlord’s Remedies.    Upon the occurrence of a Default, the following shall apply:

(i)Landlord may upon providing notice to Tenant reenter and repossess the Premises and dispossess Tenant by summary proceedings or otherwise (provided any such non-judicial action does not constitute a breach of the peace or contravene local or state laws), as well as the legal representative(s) of Tenant and/or other occupant(s) of the Premises and remove their effects, and terminate this Lease.

(ii)Landlord may accelerate all Fixed Basic Rent and additional rent for a period of twelve (12) months from the Event of Default (or such lesser time as would otherwise remain in the Term) and for all unamortized tenant improvement allowances, free or reduced Fixed Basic Rent, and leasing commissions actually granted to Tenant or incurred by Landlord, and declare the same to be immediately due and payable. Landlord shall thereafter be entitled to accelerate all Fixed Basic Rent and additional rent for additional twelve (12) month period(s) on the anniversary of such Event of Default for the remainder of the Term thereafter (or such lesser time as would otherwise remain in the Term). Landlord shall use commercially reasonable efforts to relet the Premises at market rent and receive rent therefrom, provided, however, Tenant shall not be entitled to receive any such rent and shall remain liable for the equivalent of the amount of all Rent reserved herein less the avails of reletting, after deducting therefrom all reasonable expenses incurred by Landlord in pursuing its remedies, such as (by way of illustration and not limitation) those for reasonable attorneys’ fees, brokerage, advertising, and refurbishing the Premises in good order or preparing them for re-rental. In determining the amount of any future payments due

Landlord due to increases in Operating Expenses, Landlord may make such determination based upon the amount of Operating Expenses paid by Tenant for the full year immediately prior to such Default and may assume that such expenses will increase three percent (3%) each year.

(iii)Landlord may, at any time after the occurrence of any event of Default, re-enter and repossess the Premises and/or any part thereof (provided any such non-judicial action does not constitute a breach of the peace or contravene local or state laws) and use commercially reasonable efforts to relet all or any part of such Premises for and upon such terms and to such persons, firms or corporations and for such period or periods as Landlord, in its sole discretion, shall determine, including for a term extending beyond the expiration date of the Term; provided, however, Tenant shall remain liable for the equivalent of the amount of all Rent reserved herein less the avails of reletting, after deducting therefrom all reasonable expenses incurred by Landlord in pursuing its remedies. For the purposes of such reletting, Landlord may decorate or make repairs, changes, alterations or additions in or to the Premises to the extent reasonably deemed by Landlord desirable or convenient; and the cost of such decoration, repairs, changes, alterations or additions shall be charged to and be payable by Tenant as additional rent hereunder, as well as any reasonable brokerage and legal fees expended by Landlord; and any sums collected by Landlord from any new tenant obtained on account of Tenant shall be credited against the balance of the Rent due hereunder as aforesaid;

(iv)For a non-montetary Default, enter upon the Premises and do whatever Tenant is obligated to do under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand for any expenses which Landlord may incur in effecting compliance with Tenant’s obligations under this Lease plus fifteen percent (15%) of such cost to cover overhead plus interest at the past due rate provided in this Lease, and Tenant further agrees that Landlord shall not be liable for any damages resulting to Tenant from such action. No action taken by Landlord under this Section 16.2(iv) shall relieve Tenant from any of its obligations under this Lease or from any consequences or liabilities arising from the failure to perform such obligations.

(v)Recover any and all costs incurred by Landlord resulting directly, from the Default, including but not limited to reasonable attorneys’ fees and costs, but excluding punitive damages and consequential damages not otherwise expressly specified in this Lease.

(vi)Exercise any and all other remedies available to Landlord in this Lease, at law or in equity.

(vii)WHEN THIS LEASE SHALL BE DETERMINED BY CONDITION BROKEN, EITHER DURING THE ORIGINAL TERM OF THIS LEASE OR ANY RENEWAL THEREOF, AND ALSO WHEN AS SOON AS THE TERM HEREBY CREATED EXPIRES OR IS EARLIER TERMINATED, UPON NOT LESS THAN THIRTY (30) DAYS PRIOR WRITTEN NOTICE TO TENANT, IT SHALL BE LAWFUL FOR ANY ATTORNEY TO APPEAR AS ATTORNEY FOR THE TENANT AND TO ENTER IN ANY COMPETENT COURT AN AMICABLE ACTION AND JUDGMENT IN EJECTMENT AGAINST TENANT AND ALL PERSONS OR ENTITIES CLAIMING UNDER TENANT FOR THE RECOVERY BY LANDLORD OF POSSESSION OF THE PREMISES, FOR WHICH THIS LEASE SHALL BE SUFFICIENT WARRANT; WHEREUPON, IF LANDLORD SO DESIRES, A WRIT OF POSSESSION MAY ISSUE FORTHWITH WITHOUT ANY PRIOR WRIT OR PROCEEDING WHATSOEVER, AND PROVIDED THAT, IF FOR ANY REASON AFTER SUCH ACTION SHALL HAVE BEEN COMMENCED THE SAME SHALL BE DETERMINED AND THE POSSESSION OF THE PREMISES HEREBY DEMISED SHALL REMAIN IN OR BE RESTORED TO TENANT, LANDLORD SHALL HAVE THE RIGHT, UPON ANY

SUBSEQUENT DEFAULT OR DEFAULTS OR UPON THE TERMINATION OR EXPIRATION OF THIS LEASE, TO BRING ONE OR MORE SUCH AMICABLE ACTION OR ACTIONS TO RECOVER POSSESSION OF THE SAID PREMISES. IT SHALL NOT BE NECESSARY TO FILE THE ORIGINAL LEASE AS A WARRANT OF ATTORNEY, ANY RULE OF COURT, CUSTOM OR PRACTICE TO THE CONTRARY NOTWITHSTANDING.

(viii)The rights and remedies given to Landlord in this Lease are distinct, separate and cumulative remedies; and not one of them, whether or not exercised by Landlord, shall be deemed to be in exclusion of any of the others, and the right to confess judgment in ejectment given in (vii) above may be exercised concurrently and the power of attorney to confess judgment shall not be exhausted by a single confession in each case, but shall be exercised singularly or together from time to time and as often as may be necessary to protect the rights of Landlord and shall survive any expiration or termination of this Lease.

16.3.Landlord shall have the right to seek an injunction, in the event of a breach or threatened breach by Tenant of any of the agreements, conditions, covenants or terms hereof, to restrain the same and the right to invoke any remedy allowed by law or in equity, whether or not other remedies, indemnity or reimbursements are herein provided.

16.4.TENANT UNDERSTANDS IT IS WAIVING IMPORTANT LEGAL RIGHTS BY AGREEING TO THIS PARAGRAPH 16 AND DOES SO IN THIS COMMERCIAL, NON- RESIDENTIAL TRANSACTION KNOWINGLY AND VOLUNTARILY AND AFTER ASCERTAINING THE LEGAL EFFECT HEREOF.

16.5 Landlord shall be in default under this Lease if Landlord breaches any provision of this Lease and that breach remains uncured for a period of thirty (30) days after Tenant has provided written notice to Landlord of the breach, but if that breach cannot reasonably be remedied by Landlord within thirty

(30) days after notice of breach, then Landlord shall have additional time as may be reasonably necessary to remedy the breach if during that time Landlord is continuously and diligently pursuing the remedy necessary to cure the breach. In the event of Landlord’s default (that remains uncured after applicable notice and cure periods), Tenant shall have the right to pursue all remedies available at law or in equity, except as otherwise agreed to by Tenant under the terms of this Lease.

17.CONDITION OF PREMISES. Subject to the Landlord’s Work and this Section 17, Tenant shall accept the Premises in its “AS IS,” “WHERE IS,” and “WITH ALL FAULTS” condition on the Commencement Date. Landlord represents and warrants to Tenant that as of the Commencement Date, the Premises and Common Areas will be in compliance with all applicable laws and the building systems serving the Premises, including but not limited to the building mechanical, electrical, plumbing, lighting, and roofing systems (but excluding all Tenant Improvements, furniture, fixtures and equipment), will be in good working order and consistent with operation of a Class A office building.

21.TENANT IMPROVEMENTS.

21.1Scope and Performance of Tenant Improvements. Tenant desires to perform, or cause the performance of, certain leasehold improvement work in the Premises as described on the Final Construction Drawings (below defined) (collectively, as such work shall be identified in the Final Construction Drawings, the “Tenant Improvements”). The Tenant Improvements shall be the responsibility of and performed by Tenant using PJ Dick Incorporated as the general contractor (the “General Contractor”), pursuant to the terms of that certain change order (identified as RCO No. 0111), as modified by that certain Addendum to Change Order, among Landlord, Pennley Park South, Inc., General Contractor and Tenant, dated on or around the date of this Lease (collectively, the “Change Order”). For purposes of this Section 21, the term “Cost of Tenant Improvements” shall mean and include any and all hard and soft costs and expenses associated with the design, engineering, permitting, construction management, and construction of the Tenant Improvements, and including without limitation all labor (including overtime) and materials, and the cost of any and all third-party professionals, any signage and data/telco/wiring costs. Notwithstanding the foregoing, the TI Allowance (as defined below) may not be allocated by Tenant to the purchase of furniture, fixtures, or equipment. During the completion of any Tenant Improvements, Tenant shall be solely responsible for determining what measures, if any, should be taken in order to protect any of Tenant’s personnel and Tenant’s computers, equipment, furnishings, trade fixtures and other items of personal property for potential damage that may be caused by the performance of the Tenant Improvements. Tenant, for the safety of its employees, agents, and invitees, shall be responsible for ensuring that no Tenant party enters any area in which Tenant Improvements are being completed. Tenant, at its sole costs, is solely responsible for obtaining any and all necessary documents, permits, or other governmental approvals authorizing the completion of the Tenant Improvements.

The Tenant Improvements are anticipated to be completed concurrently with the completion of Landlord’s Work (as such term is defined in Section 21.6), pursuant to the Change Order. Notwithstanding that the Tenant Improvements are being completed pursuant to such Change Order to Landlord’s existing contract with the General Contractor, the completion of the Tenant Improvements shall be supervised by and be completed at Tenant’s sole direction and Landlord shall have no liability for the completion of the Tenant Improvements, the Final Construction Drawings, or otherwise. Landlord’s only obligation with respect to the completion of the Tenant Improvements is for the disbursement of the TI Allowance in accordance with the terms and conditions set forth in this Section 21.

21.2Tenant Improvement Allowance. Subject to the conditions herein, Landlord agrees to provide to Tenant an allowance with respect to the Cost of Tenant Improvements in the total amount not to exceed Two Million Two Hundred Ninety-Five Thousand Four Hundred Eighty and 00/100 Dollars ($2,295,480.00) (the “TI Allowance”). In no event shall Landlord be obligated to provide any allowance or other contribution related to the completion of the Tenant Improvements in excess of the TI Allowance. The TI Allowance shall be applied to the Cost of Tenant Improvements and shall be payable in accordance with Paragraph 21.5.

21.1Construction Drawings. After the Effective Date of this Lease, Tenant may, at Tenant’s expense (subject to allocation of the TI Allowance), prepare construction drawings depicting the proposed Tenant Improvements (“Construction Drawings”) for Landlord’s prior written approval; which approval shall not be unreasonably withheld or conditioned by Landlord, and shall be granted or withheld (with reasonable rationale) by Landlord within ten (10) business days of Tenant’s request. In the event that Landlord fails to timely approve or disapprove of the Construction Drawings, Tenant shall deliver a second written notice to Landlord for approval. After delivery of the second written notice, Landlord shall grant or withhold approval within ten (10) business days thereafter, failing which the proposed Construction Drawings shall be deemed approved by Landlord. Upon Landlord’s approval hereunder, such proposed Construction Drawings shall be deemed to be the “Final Construction Drawings”. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of the proposed Tenant Improvements, Landlord has made no representation or warranty to Tenant with respect whether the same is acceptable for any governmental approvals and permits or with respect to the design and engineering of any such work.

21.2Cost of Tenant Improvements. Tenant shall pay for the Cost of the Tenant Improvements; provided however that such responsibility of Tenant hereunder shall be subject to Landlord’s application of the TI Allowance in accordance with Section 21.5 hereof.

21.3Payment of TI Allowance and Excess.

(i)Landlord shall disburse the TI Allowance directly to Tenant’s general contractor, engineers, suppliers, and subcontractors in accordance with the respective contracts therefor, for Tenant Improvements completed in the Premises; provided, however that: (A) Tenant shall review each such invoice and acknowledge Tenant’s approval of the invoice by signature on each invoice, (B) such installments of the TI Allowance shall be payable by Landlord no more than once per month, and upon at least thirty (30) days’ written notice from Tenant; (C) the maximum amount paid by Landlord shall not exceed the TI Allowance specified in Section 21.2, and (D) each such requisition from Tenant shall include:

(1) commercially-reasonable written specifications and corroboration of the scope of, and of all costs incurred by Tenant for, the Tenant Improvements to which such requisition relates; (2) a certificate from Tenant’s architect certifying completion of such portion of the Tenant Improvements in substantial accordance with the Final Construction Drawings, which shall be in the standard American Institute of Architects form; (3) a complete list of all contractors, subcontractors, vendors and/or suppliers providing materials and/or labor for such portion of the Tenant Improvements; and (4) mechanics’ lien releases from all contractors on account of such portion of the Tenant Improvements (collectively, a “RequisitionRequest”). Landlord shall not reimburse Tenant for any late payment fees, interest, or other charges that may have been incurred by Tenant. Landlord, upon receipt of a Requisition Request and prior to making payment, shall have the right to inspect the Tenant Improvements and the materials supplied to ensure that such work has been completed in substantial accordance with the Final Construction Drawings. Landlord and Tenant acknowledge that all risk of the costs and expenses of the Tenant Improvements exceeding the Budgeted Amount or TI Allowance shall be Tenant’s sole responsibility, subject to Landlord’s application of the TI Allowance pursuant to this Section 21. Notwithstanding the foregoing, in addition to other remedies Tenant may have at law or in equity, in the event Landlord fails to timely pay Tenant’s general contractor, engineers, suppliers, and subcontractors in accordance with this Section 21.5, then Tenant may, at Tenant’s sole discretion, make such payment on behalf of Landlord and offset such amount paid by Tenant against Rent next owing by Tenant.

(ii)In the event that the costs associated with the completion of the Tenant Improvements exceeds the TI Allowance, (A) Tenant shall timely pay all invoices when due and other charges associated with the Tenant Improvements that exceed the TI Allowance and (B) upon receipt of an invoice from the General Contractor or Landlord, Tenant shall make payment directly to the General

Contractor in accordance with the payment terms set forth in the invoice and obtain all applicable mechanics’ lien releases identified in Section 21.5(i) above.

(iii)Tenant shall indemnity, defend, and hold Landlord harmless from any damages, injuries, claims, causes of action, and other items arising out of Tenant’s completion of the Tenant Improvements, including mechanics’ liens, and ensuring compliance with all applicable laws (including the Americans’ With Disabilities Act), regulations, and ordinances.

(iv)Intentionally omitted.

21.6Landlord’s Work. Tenant acknowledges that as of the Effective Date of this Lease, Landlord is causing certain base building improvements, shown on Exhibit G, to be completed in the Office Unit at Landlord’s sole cost and expense (collectively, the “Landlord’s Work”). Landlord shall use commercially reasonable efforts to cause the Landlord’s Work to be substantially completed on or before May 1, 2022 (the “Anticipated Completion Date”). Landlord’s Work shall be deemed to have been “substantially completed” when a certificate of occupancy or an equivalent approval or certificate is issued by the applicable governmental authority to permit occupancy (including, but not limited to, a temporary certificate of occupancy) of the Demised Premises or the issuance of an AIA G704 (Certificate of Substantial Completion) by the General Contractor and either Tenant’s architect or one of Tenant’s authorized representatives (as identified in the Change Order), whichever shall occur first. Within three (3) business days after Landlord delivers the Premises to Tenant, Tenant shall deliver to Landlord a list of punch list items. To the extent such items identified by Tenant are included on Exhibit G, Landlord shall correct or cure the punch list items within 30 business days after Landlord receives the punch list, or such longer period as may be necessary, provided Landlord is proceeding with due diligence to complete those items. Upon Tenant’s occupancy, Tenant shall execute a Commencement Date Agreement in the form of Exhibit E attached hereto.

If the Commencement Date does not occur by the Anticipated Completion Date, then Tenant shall be entitled to abatement of Rent equal to one day of Fixed Basic Rent for the number of days between the Anticipated Completion Date and the actual Commencement Date, which abatement shall begin in the thirteenth (13th) month of the Lease. Tenant and Landlord each acknowledge and agree that the completion of the Tenant Improvements (as such term is defined in Section 21.1 hereof) shall have no application to the determination of the substantial completion of Landlord’s Work. The Anticipated Completion Date shall be extended because of any delay caused by a Tenant Delay or events of Force Majeure. As used herein, “Tenant Delay” shall mean a delay caused by changes, additions or deletions to the Landlord’s Work requested by Tenant. Landlord shall, and shall cause its contractors to, work in harmony with and not unreasonably interfere with the performance of the Tenant Improvements in the Premises and Tenant shall and shall cause its contractors to work in harmony with and not unreasonably interfere with the performance of the Landlord’s Work in the Premises.

Landlord further agrees to use commercially reasonable efforts to cause construction of the Building to be substantially completed on or before the Anticipated Completion Date and if any work or punch list items related thereto are performed after the Commencement Date, Landlord shall perform such work in accordance with the terms of Section 11.1.

22.HAZARDOUS SUBSTANCES.

22.1.Tenant shall not and shall not cause or allow its employees, contractors or agents to generate, treat, store, or dispose of Hazardous Substances on or near the Property, Premises, or the Office Unit, Tenant shall at all times comply with all applicable Environmental Laws, and Tenant will keep the Premises free of any lien imposed pursuant to any Environmental Laws by reason of breach of any of the

foregoing representations, warranties and covenants. “Hazardous Substances” shall mean (i) any hazardous substance as that term is defined in the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), 42 U.S.C. 9601 et seq., as amended, (ii) any hazardous waste or hazardous substance as those terms are defined in any local, state or federal law, regulation and ordinance applicable to the Property (collectively the “Environmental Laws”), or (iii) petroleum, including crude oil or any fraction thereof. In the event Tenant uses any Hazardous Substances, Tenant shall dispose of such substances in accordance with all applicable federal, state, and local laws, regulations and ordinances. Further, limited quantities of cleaning products and office supplies used or stored at the Premises and required in connection with the routine operation and maintenance of the Premises, and in compliance with all applicable Laws shall be permitted without Landlord’s consent.

22.2.Tenant agrees to indemnify, defend and hold harmless Landlord, its employees, agents, successors, and assigns, from and against any and all damage, claim, liability or loss, including reasonable attorneys' and other fees, arising out of or in any way connected to the generation, treatment, storage or disposal of Hazardous Substances by Tenant, or its employees, agents, contractors, or invitees, on or near the Property. Such duty of indemnification shall include, but to be limited to, damage, liability, or loss pursuant to all federal, state and local environment laws, rules and ordinances, strict liability and common law.

22.3.The provisions of this Section 22 shall survive any termination of this Lease or the Term.

23.CONFIDENTIALITY. Landlord and Tenant each agree that they shall maintain in confidence and shall not divulge to any third party (except as required by law) any of the terms, covenants and conditions of this Lease, including without limitation, any information related to the rental rate, the length of the Term, any renewal, termination, expansion, contraction or similar options, if any, or the amount of any free rent, improvement allowance or other concessions granted to Tenant by Landlord under this Lease, except to their respective employees, attorneys, auditors, lenders and brokers or as otherwise required by law (including, without limitation, public company reporting requirements). Landlord and Tenant further agree to take commercially reasonable precautions to prevent the unauthorized disclosure of any of such information to any other third parties. Landlord shall not (and shall not permit its broker’s or contractors to) use Tenant’s name (or make any other reference that may identify Tenant), including without limitation, on websites or marketing materials, without Tenant’s prior approval (which may be granted or withheld in Tenant’s sole discretion). Landlord’s and Tenant's obligations under this Section 23 shall survive termination of this Lease.

24.VEHICLE PARKING. During the Term and subject to all terms, conditions, and provisions in this Lease and any rules and regulations adopted by Landlord or any garage operator from time to time, Tenant's occupancy of the Premises will include the use of the Parking Spaces set forth in the Basic Lease Provisions. Tenant will, upon request, promptly furnish to Landlord the license numbers of the cars operated by Tenant and its subtenants, invitees, concessionaires, licensees and their respective officers, agents and employees.

Except as set forth below, all parking spaces are unreserved and available to card access users, tenants, invitees, and guests of the Office Unit on a first come, first serve basis. Notwithstanding the foregoing, nineteen (19) parking stalls situated on the ground floor level of the parking garage may be designated for the sole use of the retail tenant(s) in the Office Unit. Tenant’s parking rights are the personal rights of Tenant and Tenant shall not transfer, assign, or otherwise convey its parking rights provided herein separate or apart from this Lease.

25.RIGHT OF FIRST REFUSAL. During the Term, Tenant shall have rights of first refusal (the “ROFR Option”) to lease: (a) that certain eastern portion (i.e. S.

The Termination Fee (as such term is defined in Section 29 hereof) shall be adjusted to include 50% of the Fixed Basic Rent payable for such expansion space for the ninth, tenth and eleventh years of the Term. If Tenant effectively exercises the ROFR Option during the initial 36-month period as provided herein, then Landlord and Tenant shall promptly thereafter enter into a lease amendment amending this Lease to confirm such exercise and reflect the terms and conditions set forth herein and in the ROFR Notice.

B.Exercise After Initial 36 Months. Upon the expiration of the thirty-sixth (36th) month of the Term, Tenant’s exercise of its ROFR Option for any portion of the 2nd Floor ROFR Premises shall be subject to the same terms and conditions as the third-party offer, including, but not limited to, the rental rate, term, and commencement date set forth in the Offer. If Tenant effectively exercises the ROFR Option as provided in this Section 25.2.B., then Landlord and Tenant shall promptly thereafter enter into a supplemental lease agreement confirming such exercise and reflecting the terms and conditions set forth herein and in the ROFR Notice.

25.34th Floor ROFR Premises.

25.4ROFR Conditions. The ROFR Option must be exercised, if at all, on and subject to the following terms and conditions: (i) Tenant shall deliver written notice to Landlord not later than ten (10) days following the date of Tenant’s receipt of the ROFR Notice, time being of the essence; (ii) at the time of exercising the ROFR Option, this Lease shall be in full force and effect and there shall then exist no uncured Event of Default of Tenant; (iii) Tenant shall be in occupancy of the entire Premises, and (iv) Tenant must lease all square footage set forth in the Offer even if greater in size than the ROFR Premises.

25.5Termination of ROFR Option; Partial Termination. If Tenant fails to timely exercise its ROFR Option, Tenant will be conclusively deemed to have elected not to exercise its ROFR Option with respect to that portion of the ROFR Premises identified in the Offer; in which event, the ROFR Option shall no longer apply and is thereafter deemed null and void.

25.6Assignment of Lease. This entire Section 25 shall automatically terminate and become null and void upon the assignment by Tenant of this Lease, in whole or in part, or the sublease by Tenant of all or any part of the Premises (except for a Permitted assignment or Permitted Sublease pursuant to Paragraph 15 herein).

26.OUTDOOR TERRACE.

Any Sign permitted by Landlord in writing, shall at all times conform to all municipal ordinances or other laws, regulations, deed restrictions, and other covenants applicable thereto. Tenant shall remove all Signs at the expiration or other termination of this Lease, at Tenant’s sole risk and expense, and shall in a good and workmanlike manner properly repair any damage caused by the installation, existence, or removal of Tenant’s Signs. Notwithstanding the foregoing, subject to applicable laws and related approvals, Tenant shall have the right to install one exterior building sign on the Euclid Avenue Façade of the Building in the location shown on the attached Exhibit I, provided, (i) that the total face area of such sign does not exceed 80 square feet, (ii) that all costs and expenses associated with the signage, including permitting, shall be Tenant’s sole responsibility, and (iii) Tenant shall obtain all necessary permits and approvals under federal, state, or local laws and regulations and maintain all such approvals during the period in which the signage remains on the Office Unit.

In the event that all or a substantial portion of the Premises or the Property are taken by eminent domain so that the Premises cannot be reasonably used by Tenant for the purposes for which they are demised or, in the reasonable judgment of Landlord, so that the Office Unit cannot be operated as an integral unit (whether or not the Premises are affected), then either party may terminate this Lease by giving written notice of termination to the other party within thirty (30) days after such taking. In the event of any taking by eminent domain, the entire award shall be paid to and retained by Landlord excepting, however, that Tenant may receive therefrom any portion paid on account of Tenant's relocation expenses and construction of leasehold improvements within the Premises.

This Lease and the Exhibits attached hereto contain the entire agreement between Landlord and Tenant concerning the Premises and there are no other agreements, either oral or written.

28.5.No Waiver. No receipt of money by Landlord from Tenant after the termination of this Lease or Tenant's right of possession of the Premises shall reinstate, continue or extend the Term. The failure or delay of either party to enforce or exercise at any time any of the provisions, rights, or remedies in this Lease shall in no way be construed to be a waiver thereof, nor shall same in any way affect the validity of this Lease or any part hereof, or the right of such party to hereafter enforce each and every such provision, right or remedy.

Tenant represents that, except for the brokers, if any, specified in Section 1.Y., Tenant has not dealt with any real estate broker, sales person, or finder in connection with this Lease. Tenant hereby agrees to defend indemnify and hold harmless Landlord, its agents and employees, from and against any and all liabilities and claims for commissions and fees arising out of a breach of the foregoing representation. Unless otherwise agreed by the parties, Landlord shall be responsible for the payment of all commissions to the broker, if any, specified in Section 1.Y., based upon Landlord's separate agreement with such broker.

Such excuse from non-monetary performance shall be effective only to the extent and duration of the event(s) prohibiting

28.11.Landlord May Perform Tenant's Obligations. If Tenant fails to timely perform any of its duties under this Lease, Landlord shall have the right (but not the obligation), after the expiration of any grace period elsewhere under this Lease expressly granted to Tenant for the performance of such duty, to perform such duty on behalf and at the expense of Tenant without further prior notice to Tenant, and all sums expended or expenses incurred by Landlord in performing such duty, along with a three percent (3%) service charge, shall be deemed to be additional rent under this Lease and shall be due and payable within thirty (30) days of invoice by Landlord.

28.12.Claims. Tenant waives all claims it may have against Landlord and the Building Manager and their respective agents or employees, for injury or damage to person, property or business sustained by Tenant, its agents, employees or invitees resulting directly or indirectly from the Property, equipment therein, or any part of the Premises becoming out of repair or resulting from any accident within the Property unless due to the negligence or willful conduct of Landlord, Building Manager or their respective agents or employees. This provision shall apply without limitation to damage caused by water, snow, frost, steam, gas, sewer gas or odors, or by the bursting or leaking of pipes or plumbing works or the failure of any appurtenances or equipment.

costs, charges and expenses, including reasonable fees of attorneys, agents and others retained or employed by the prevailing party in proceedings involving the obligations and undertakings of the parties hereunder, and all costs, charges and expenses incurred in any lawsuit, in which one party causes the other party to become involved or concerned, that are awarded by a court of law.

28.18Time of the Essence. Time is of the essence of each provision of this Lease.

29.EARLY TERMINATION OPTION.

29.1So long as no Default of Tenant has occurred and is continuing at the time Tenant gives Landlord notice exercising the Early Termination Option herein granted or thereafter until the Early Termination Date (unless Landlord in its sole discretion at any time shall elect to waive such condition), Tenant shall have a one-time option (the “Early Termination Option”) to terminate this Lease with respect to the entire Premises with such termination to be effective as April 30, 2030 (as applicable, the “EarlyTermination Date”) by giving Landlord written notice of Tenant's election to exercise the Early Termination Option (the “Early Termination Notice”) not later than April 30, 2029, time being of the essence with respect to the giving of such notice. If Tenant does not timely deliver the Early Termination Notice prior to April 30, 2029, the Early Termination Option shall expire, and Tenant shall have no further right to terminate the Lease.

29.2Tenant shall pay to Landlord concurrent with the delivery of the Early Termination Notice, a Termination Fee equal to $2,891,612.67, which amount may be increased in accordance with the terms and conditions herein (the “Termination Fee”).

29.3Time shall be of the essence with regard to Tenant’s responsibilities under this Early Termination Option, and in the event that Tenant fails to timely deliver the Early Termination Notice or to timely pay the Termination Fee, such failure shall be deemed a waiver by Tenant of its right to terminate the Lease.

29.4If Tenant timely and properly exercises the Early Termination Option, Tenant shall vacate the Premises and deliver possession thereof to Landlord in the condition required by the terms of the Lease on or before the Early Termination Date and neither Landlord nor Tenant shall have further obligations under the Lease with respect to the Premises except for those accruing prior to the Early Termination Date and those which, pursuant to the terms of the Lease, survive the expiration or early termination of the Lease.

To the extent that Tenant does not timely vacate the Premises, the Tenant will be deemed to be a holdover Tenant and subject to Paragraph 14 of the Lease. Any purported attempt to terminate the Lease with respect to the Premises, or any portion thereof, that is not in conformity with the terms and conditions as set forth in this Paragraph 29 shall be deemed to be null, void and of no effect.

30.OPTIONS TO EXTEND

30.1Subject to the terms of this Section 30, Tenant shall have two (2) option(s) to extend the term of this Lease for an additional period of five (5) years (each an “Option Period” and collectively, the “Option Periods”), with each such Option Period to begin upon the expiration of the Term (as the same may have been extended) on the same terms and conditions set forth herein, except that (i) no concessions, abatements or allowances granted with respect to the Term hereof shall be applicable to the Option Period,

(ii) Fixed Basic Rent shall be adjusted as set forth in this Section 30 and (iii) Option Period, once exercised, cannot be exercised again.

30.2Tenant shall provide Landlord with written notice of its desire to extend the Term for an Option Period (the “Extension Notice”) not less than 12 months prior to the scheduled expiration of the Term (as the same may have been previously extended by an Option Period) (the “Renewal Deadline”). Failure by Tenant to deliver to Landlord the Extension Notice on or before the Renewal Deadline shall be deemed a conclusive waiver of such option to extend the Term of this Lease. If Tenant shall extend the Term hereof pursuant to the provisions of this Paragraph 30, such notice shall be irrevocable and the extension shall (subject to satisfaction of the Renewal Conditions, as defined in Paragraph 30.6 below, unless waived by Landlord) be automatically effected without the execution of any additional documents, but the parties shall, at either of Landlord’s or Tenant’s request, execute an agreement confirming the total Fixed Basic Rent for the Renewal Term. Notwithstanding anything to the contrary contained in this Paragraph 30, the failure of the parties to execute any amendment with respect to Tenant’s exercise of the Renewal Option shall not be deemed to rescind Tenant’s notice of its exercise of the Renewal Option and Tenant shall remain bound by its election under this Paragraph 30.

30.3If Tenant timely delivers an Extension Notice, Landlord shall deliver to Tenant, within 30 days after receipt of the Extension Notice, notice (the “Rent Notice”) of Landlord’s determination of the Fixed Basic Rent for the first year of the applicable Option Period (the “Option Period Fixed Basic Rent”), which shall be the then prevailing Fair Market Fixed Basic Rent (defined below) for the Premises. If Tenant does not agree with Landlord’s determination, then Landlord and Tenant shall commence negotiations to attempt to agree on each party’s determination of the Option Period Fixed Basic Rent within 30 days after Landlord’s delivery of its Rent Notice to Tenant. If the parties cannot agree upon the Option Period Fixed Basic Rent by the date that is thirty (30) days following delivery of the Rent Notice, then either party, prior to the date which is sixty (60) days before the commencement of the Option Period, may deliver written notice to the other to request that the Option Period Fixed Basic Rent be determined by appraisal. If neither party timely delivers such request, the Fixed Basic Rent as set forth in the Landlord Rent Notice shall be the applicable rental rate for the Option Period and not subject to further adjustment.

If so elected by either party, the determination of the Option Period Fixed Basic Rent shall be submitted to appraisal as follows: Within fifteen (15) days after one party delivers written notice to the other electing for the Option Period Fixed Basic Rent to be determined by appraisal, Landlord and Tenant shall each give notice to the other specifying the name and address of the appraiser each has chosen. The two appraisers so chosen shall meet within ten (10) days after the second appraiser is appointed and if, within twenty (20) days after the second appraiser is appointed, the two appraisers shall not agree upon a determination of the Option Period Fixed Basic Rent in accordance with the following provisions of this Section 30 they shall together appoint a third appraiser. If only one appraiser shall be chosen whose name and address shall have been given to the other party within such fifteen (15) day period and who shall have the qualifications

hereinafter set forth, that sole appraiser shall render the decision which would otherwise have been made as hereinabove provided.

If said two appraisers cannot agree upon the appointment of a third appraiser within ten (10) days after the expiration of such twenty (20) day period, then either party, on behalf of both and on notice to the other, may request such appointment by the then President of the Real Estate Board (or any similar or successor organization) for the greater Pittsburgh area in accordance with its then prevailing rules. If said President shall fail to appoint said third appraiser within ten (10) days after such request is made, then either party, on behalf of both and on notice to the other, may request such appointment by the American Arbitration Association (or any successor organization) in accordance with its then prevailing rules. In the event that all three appraisers cannot agree upon such Option Period Fixed Basic Rent within ten (10) days after the third appraiser shall have been selected, then each appraiser shall submit his or her designation of such Option Period Fixed Basic Rent to the other two appraisers in writing; and Option Period Fixed Basic Rent shall be determined by calculating the average of the two numerically closest (or, if the values are equidistant, all three) values so determined. Both appraisers or a majority of them (or the sole appraiser, if applicable) shall determine the Option Period Fixed Basic Rent of the Premises for the Option Period and render a decision and award as to their determination to both Landlord and Tenant (a) within twenty (20) days after the appointment of the second appraiser, (b) within twenty (20) days after the appointment of the third appraiser or (c) within fifteen (15) days after the appointment of the sole appraiser, as the case may be.

30.4If the dispute between the parties as to the Option Period Fixed Basic Rent has not been resolved before the commencement of Option Period based upon determination of such Option Period Fixed Basic Rent, then Tenant shall pay the total Fixed Basic Rent under the Lease based upon the Fixed Basic Rent payable as of the expiration of the Term as escalated by 2% per annum until either the agreement of the parties as to the Option Period Fixed Basic Rent, or the decision of the appraiser(s), as the case may be, at which time Tenant shall pay any underpayment of the Fixed Basic Rent to Landlord, or Landlord shall refund any overpayment of the Fixed Basic Rent to Tenant.

30.5On the anniversary of the first day of the applicable Option Period, Fixed Basic Rent shall be increased to an amount equal to the product of (a) the Fixed Basic Rent amount in effect immediately prior to that increase, multiplied by (b) 1.02.

30.5“Fair Market Fixed Basic Rent” shall mean the base rent (exclusive of Additional Rent which shall be paid as provided elsewhere in this Lease) at which a willing landlord would lease comparable premises as the Premises in a comparable building as the Building (“comparable” being determined on the basis of age, square footage, size and existing tenant improvements, furniture, fixtures and equipment, all taken “as is where is” without imposing any artificial schedule of depreciation or artificial schedule of amortization of useful life) to a willing tenant of comparable creditworthiness as the creditworthiness of Tenant as determined on the last day of the Term immediately prior to the commencement of the applicable Option Period and for a lease term commensurate with the Option Period (with effect given to any additional renewal periods set forth in the Lease) commencing on the last day of the then-current Term and that is similar in all material economic and non-economic respects to this Lease. Fair Market Fixed Basic Rent shall not be reduced by reason of any costs or expenses saved by Landlord by reason of Landlord’s not having to find a new tenant for the Premises (including brokerage commissions, costs of improvements necessary to prepare the space for such tenant’s occupancy, rent concession, or lost rental income during any vacancy period) nor shall it be increased by Tenant’s cost of moving or the amount of the unamortized portion of Tenant’s alterations. Notwithstanding anything to the contrary herein, the Fair Market Fixed Basic Rent shall not be less than the Fixed Basic Rent for the last month of the Term prior to the commencement of the Option Period as escalated by 2%.

30.6Renewal Conditions. The “Renewal Conditions” include that, as of the date of the Extension Notice, (i) there shall not exist any Default of Tenant under the Lease which remains uncured beyond any applicable cure period, (ii) the named Tenant, as then set forth in the Lease (including, without limitation, all permitted assigns), shall actually occupy the entire Premises, and (iii) there shall be no allowance or inducements payable by Landlord during the Renewal Term. Landlord, at its sole option, may waive any Renewal Conditions.

31.GENERATOR

31.1 During the Term Tenant shall have the right, at Tenant’s sole option, cost, and expense, to install one (1) emergency backup generator that is owned by Tenant in a location mutually agreed to by Landlord and Tenant on the Property, subject to Landlord’s approval of Tenant’s plans and specifications for such installation, including, size, applicable required landscaping, and sound mitigation requirements and subject to the terms and conditions set forth in Exhibit J. Landlord shall not unreasonably withhold Landlord's consent subject to Tenant (a) obtaining Landlord's prior approval of final plans and specifications; (b) obtaining Landlord's prior approval of all contractors and subcontractors and their respective contracts; (c) obtaining all permits, approvals, and certificates required by any governmental or quasi-governmental bodies and, upon completion, certificates of final approval and shall deliver promptly duplicates of all such permits, approvals and certificates to Landlord; and (d) prior to occupancy by Tenant and/or commencement of any alterations or improvements by contractors or subcontractors, providing proof of coverage by any contractor by a certificate and/or copy of the policy complying with all insurance requirements set forth herein, as the same may be changed by written notice from Landlord to Tenant from time to time during the Term. Landlord shall either approve or make reasonable detailed comments on any plans and specifications within five (5) business days after delivery of such plans and specifications to Landlord.

32.EXPANSION. During the initial thirty-six (36) months of the Term, Tenant shall have the right to request additional space on the second and fourth floor within the Office Unit from Landlord to the extent space is available. Tenant shall be deemed to agree to lease any such expansion space on the same terms and conditions as this Lease, except that (i) the definition of Premises shall be amended to include the expansion space, (iii) the Fixed Basic Rent payable for the expansion space shall be equal to the per square foot amount of Fixed Basic Rent then payable for the Premises, which shall be subject to adjustment pursuant to Section 1.N, (iv) Tenant’s Proportionate Share of Operating Expenses and Increases in Real Estate Taxes shall be proportionately increased based upon the addition of the expansion space to the Premises, (v) Tenant shall accept the expansion space in its “as is” condition, (vi) Landlord shall provide the same per square foot Tl Allowance as was provided for the Premises as a tenant improvement allowance for the expansion space but ratably reduced based on the length of the remaining term after the expansion space is delivered to Tenant for the construction of tenant improvements within the expansion space as approved by Landlord, (vii) Landlord shall provide the same number of parking spaces per square foot of the expansions space that was provided for the Premises, (viii) the term of the Lease shall commence with respect to the expansion space and Tenant shall commence paying Fixed Basic Rent and Additional Rent on the date that is not greater than six (6) months after the delivery of Tenant’s request to expand, and (ix) the Termination Fee (as defined in Section 29) shall be increased by an amount equal to 50% of the Fixed Basic Rent payable for such expansion space for the ninth, tenth and eleventh years of the Term.

Nothing contained in this Section shall imply any duty on the part of Landlord to pay any expense or provide any service not otherwise imposed by the express terms of this Lease.

(2)Expenses Adjustment. Tenant shall pay as Additional Rent for each Lease Year an amount (the “Expense Adjustment Amount”) equal to Tenant’s Proportionate Share of the increase in Operating Expenses for such Lease Year over the Base Year for Operating Expenses, and if the Term shall terminate on a date other than December 31, the Expense Adjustment Amount for the last Lease Year of the Term shall be an amount equal to Tenant’s Proportionate Share of the increase in Operating Expenses for the full calendar year in which the Term ends multiplied by a fraction, the numerator of which shall be the number of months and partial months during such calendar year which coincide with the Term, and the denominator of which shall be twelve.

(3)Tax Escalation. If the Real Estate Taxes for any Lease Year or Partial Lease Year during the Term will be greater than the Real Estate Taxes Base Year (adjusted proportionately to correspond to the duration of periods less than a Lease Year), then Tenant will pay to Landlord as Additional Rent, Tenant's Proportionate Share of the Increases in Real Estate Taxes.

As used herein, the term “Real Estate Taxes” shall include any form of real estate tax or assessment, general, special, ordinary or extraordinary, improvement bond or bonds imposed on the Property or any portion thereof, foreseen or unforeseen, by any authority having the direct or indirect power to tax, including any city, county, state or federal government, or any school, agricultural, sanitary, fire, street, drainage or

other improvement district thereof, as against any legal or equitable interest of Landlord in the Property. If due to a future change in the method of taxation, any franchise, income or profit tax will be levied against Landlord in substitution for, or in lieu of, or in addition to, any tax which would otherwise constitute Real Estate Taxes, such franchise, income or profit tax will be deemed to be Real Estate Taxes for purposes of this Lease (to the extent that such taxes would be payable if the Property was the only property of Landlord subject to such tax). Real Estate Taxes and Operating Expenses shall not include any income tax (or tax that is a successor thereto) or any excess profit, franchise, capital stock, estate or inheritance tax or gift tax, except as specifically provided in the preceding sentence. Any special assessments/tax and extraordinary charges shall be allocated over the maximum term allowed by law and shall include the interest charge for such allocation, and Tenant shall only be responsible to pay Tenant’s Proportionate Share of the amortized portion as it is amortized during the term of the Lease in the year such assessment is actually paid after deducting abatements, rebates or refunds, if any.

From time to time Landlord may challenge the assessed value of the Property as determined by applicable taxing authorities and/or Landlord may attempt to cause the Real Estate Taxes to be reduced. If Landlord, in Landlord’s commercially reasonable discretion, seeks to cause the Real Estate Taxes to be reduced, defends against any taxing agencies appeal seeking to increase the Real Estate Taxes, or in obtaining a refund, rebate, credit or similar benefit, all costs incurred by Landlord shall be considered an Operating Expense.

(4)Electrical Charge. From and after the Commencement Date, Tenant shall pay to Landlord the cost for the actual electricity charges incurred in the operation of the Premises based on the submeter for the Premises or other building management system’s calculation of electrical consumption within the Premises. Tenant shall pay for the first month of the Term, an estimated amount equal to $1.50 per rentable square foot, per annum, and for each month thereafter during the Term, Tenant shall pay the actual charges associated with Tenant’s use of electricity within the Premises upon receipt of an invoice from Landlord. As soon as practicable after each Lease Year or Partial Lease Year, Landlord will give Tenant a statement (the “Electric Statement”) showing the actual amounts payable by Tenant under this Rider during such Lease Year. If the Electric Statement shows that the actual amount Tenant owes for such Lease Year or Partial Lease Year is less than the estimated amount paid by Tenant during such Lease Year or Partial Lease Year, Landlord, at its option, will either return the difference or credit the difference against the next succeeding payment(s) of the monthly electric charge, provided a sufficient number of months remain in the term to exhaust the amount owed. If the Electric Statement shows that the actual amount Tenant owes is more than the estimated electrical charge paid by Tenant during such Lease Year or Partial Lease Year, Tenant will pay the difference after the following month from when the Electric Statement is delivered to Tenant. Upon request, the Landlord will provide the Tenant copies of its electrical bills.

(5)Lease Year. As used in this Lease, the defined term “Lease Year” will mean a calendar year. Any portion of the Term which is less than a Lease Year, that is, from the Commencement Date through the following December 31, and from the last January 1 falling within the Term to the end of the Term, will be deemed a “Partial Lease Year”. Any reference in this Lease to a Lease Year will, unless the context clearly indicates otherwise, be deemed to be a reference to a Partial Lease Year if the period in question involves a Partial Lease Year.

(6)Payment of Operating Expenses. For purposes of estimating an increase in Tenant’s Proportionate Share of Operating Expenses and Real Estate Taxes during each subsequent calendar year, Landlord shall estimate the increase in Tenant’s Proportionate Share for the ensuing calendar year, or, if applicable, the remaining portion thereof and notify Tenant in writing of such estimate. Such estimate shall be made by Landlord in the exercise of its sole reasonable discretion and not subject to arbitration. Landlord’s estimate shall be paid by Tenant each month during the Term of the Lease, on the same day as the Fixed Basic Rent is due hereunder. As soon as practicable after each Lease Year or Partial Lease Year, Landlord will give

Tenant a statement (the “Statement”) showing the actual amounts payable by Tenant under this Rider for such Lease Year. If the Statement shows that the actual amount Tenant owes for such Lease Year or Partial Lease Year is less than the estimated amount paid by Tenant during such Lease Year or Partial Lease Year, Landlord, at its option, will either return the difference or credit the difference against the next succeeding payment(s) of Rent, provided a sufficient number of months remain in the term to exhaust the amount owed. Notwithstanding the foregoing, in no event shall Tenant receive any reimbursement for a reduction in Operating Expenses below the Base Year for Operating Expenses. If the Statement shows that the actual amount Tenant owes is more than the estimated Additional Rent paid by Tenant during such Lease Year or Partial Lease Year, Tenant will pay the difference after the following month from when the Statement is delivered to Tenant as Additional Rent.

(7)Audit. During the Lease Term, but not more than one (1) time per year, Tenant, at its sole cost and expense (except as provided below) shall have the right to cause Landlord’s books and records with respect to Operating Expenses and Real Estate Taxes to be audited by an independent certified public accountant of Tenant's choosing. Tenant shall deliver notice of the request to audit Landlord within one hundred twenty

(120) days after delivery of the Landlord Statement. Landlord shall cause such books and records to be made available for such inspection during such normal business hours as are prescribed by Landlord and at such location where Landlord regularly keeps its books and records (or by using computer technology available to Landlord at no additional cost), upon ten (10) business days' prior notification to Tenant. If, at the conclusion of Tenant's audit, such expenses for the preceding year indicates that Tenant made an overpayment to Landlord for such preceding year, Landlord shall (a) credit such amount to Tenant's subsequent payments of Rent, or if the Lease has expired, and no default exists under the Lease, remit the amount of such overpayment to Tenant within thirty (30) days after receipt of notice from Tenant of the amount of such overpayment and (b) if the actual Operating Expenses allocable to the Premises are overstated by more than 5%, Landlord shall reimburse Tenant for the actual, reasonable out-of-pocket costs of such audit not to exceed a maximum amount of $4,500.00. If, at the conclusion of the audit, such audit reveals an underpayment by Tenant, Tenant will remit the amount of such underpayment within thirty (30) days of Tenant becoming aware of such underpayment. Should Landlord disagree with the results of Tenant's audit, Landlord and Tenant shall refer the matter to a mutually acceptable independent certified public accountant, who shall work in good faith with Landlord and Tenant to resolve the discrepancy. Landlord's books and records and the results of any such audit are to be kept strictly confidential and are not to be made available or published to any third party, unless required by any applicable legal requirement or governmental authority. The auditor employed by the Tenant shall not provide for any compensation based or measured in any way upon any savings in additional rent or reduction in Operating Expenses allocable to the Premises achieved through the inspection process described in this Paragraph and shall be paid on an hourly-basis, or similar form of compensation.

(8)Occupancy Adjustment. If the Office Unit is less than ninety-five percent (95%) occupied during the Base Year for Operating Expenses or during any Lease Year or Partial Lease Year subsequent to the Calendar Year, then the Operating Expenses will be adjusted during any such Lease Year or Partial Lease Year so as to reflect ninety-five percent (95%) occupancy. The aforesaid adjustment will only be made with respect to those items that are in fact affected by variations in occupancy levels.

Tenant Dog Policy Regulations. Tenant has enacted the following policies for dog-friendly workspaces, which policy, as may be amended from time to time by Tenant, shall, in addition to rules and regulations of Landlord, be followed by Tenant during the Term.

•Before bringing your dog to Duolingo, ensure that the office is a safe environment for them and other Duo-dogs

•Do they have all relevant vaccinations? Are they healthy?

•Sick Duos should stay home, and so should sick Duo-dogs!

•Duo-dogs should be up to date on vaccinations.

•Are they comfortable being in an office environment around other dogs and lots of people?

•Unsure if your dog will be comfortable at Duolingo? Try bringing them to the office during evenings/weekends first!

•In Pittsburgh, coordinate with other dog-owners when you bring your dog to the office using #office-dogs-pgh. We’d like to keep it to a max of 10 dogs per day.

•Be considerate to those sitting near your Duo-dog

•Ask those sitting near you if they have dog allergies! If someone who sits near you has dog allergies, please consider bringing your dog in on a day when that person is working from home and/or sit somewhere else for the day.

•Be sensitive that some Duos are afraid of dogs (even little pups).

•Give those around you a heads up beforehand so everyone can plan accordingly.

•All dogs must be leashed and supervised at all times in the common areas. Do not let your dog wander unattended.

•You are encouraged to sit in a breakout space with your dog to diminish distraction if necessary.

•Is it appropriate to bring your dog to the office daily?

•Ensure that you’re coordinating with other dog owners on a daily basis in the #office-dogs-pgh Slack channel

•Ensure that you have confirmed with those who sit around you that your dog is not a distraction and/or disruptive in any other way.

•Non-Duolingo employees should not bring their dogs to the office

•We want to guarantee the health & safety of our Duos & Duo-dogs, so non-Duo- dogs should stay out of the office.

•Duo-dogs should be housebroken

•Everyone has accidents, but if it's a recurring problem, or you are still house training your dog, please consider keeping them at home.

•If your dog has an accident, you are responsible for cleaning it up.

•Duo-dogs must stay out of sensitive areas of the office

•Specifically, the commercial kitchen and construction space. This is for the safety of our Duo-dogs and the kitchen staff!

•In Pittsburgh, do not bring dogs to the roof.

•Keep dogs off of the furniture.

Food Preparation Rules and Regulations

Tenant shall not sell any food or beverages in or from the Demised Premises at any time and/or serve any food and beverages in or from the Demised Premises at any time to other tenants or occupants of the Office Unit or Building (or their employees) or to members of the general public. No cooking odors shall be emitted from the Demised Premises other than through ventilation equipment and systems installed therein to service the Kitchen in accordance with the Lease and this Exhibit C-2.

If Tenant elects to exercise its right to operate the Kitchen, Tenant shall give Landlord prior notice thereof and shall submit to Landlord (i) construction ready plans and specifications for the Kitchen (including, any cooking, ventilation, air conditioning, grease traps, kitchen and other equipment in or for the Demised Premises with respect to the Kitchen) for Landlord’s review and approval (such submission, review and approval shall be governed by Section 10 of the Lease, however, Landlord’s period to review such plans shall be extended to a period of thirty (30) days), and (ii) all necessary consents, approvals, permits or registrations, required for the construction and operation of the Kitchen in accordance with applicable laws (including, without limitation, any necessary approvals from the applicable health and/or fire departments, permits required in connection with any venting or other air-removal/circulation system, and any required fire-suppression systems). All such Alterations (or Improvements) shall be approved by Landlord and installed and constructed at Tenant’s sole cost and expense in accordance with Section 10 of this Lease. The Kitchen and the Kitchen facilities therein shall be maintained and operated by Tenant, at Tenant’s sole cost and expense: (a) in first-class order, condition, and repair; (b) consistent with the character of the Office Unit as a first-class office building; and (c) in compliance with all applicable laws, such reasonable rules and regulations as may be adopted by Landlord from time to time, and the other provisions of the Lease. Tenant shall pay for all cleaning costs incurred by Landlord in cleaning any affected portions of the Building, Office Unit, or Demised Premises resulting from Tenant’s operation of the Kitchen, including the disposal of food and cooking wastes. In addition, Tenant shall pay for all actual and reasonable out-of-pocket increased costs incurred by Landlord with respect to the management, operation, maintenance, and repair of the Office Unit resulting from Tenant’s operation of the Kitchen, within thirty

(30)days of receiving an invoice therefor. Tenant shall have the right to remove all equipment and alterations relating to the Kitchen at the end of the Term at Tenant’s sole cost and expense, provided that Tenant shall make any repairs resulting from such removal.

Tenant shall cause to be provided pest eradication and control services, as required by Landlord in its reasonable discretion, with respect to the Kitchen. All trash generated from Tenant's Kitchen shall be stored in covered containers to prevent the emission or emanation of odors from the Kitchen, shall be sealed in double plastic bags (or otherwise sealed in a manner prescribed by or reasonably acceptable to Landlord), and shall be deposited by Tenant daily (or more often if required by Landlord in its reasonable discretion) in the area of the Office Unit or Building reasonably designated by Landlord from time to time. If Landlord reasonably determines that additional trash removal from the Office Unit shall be required as a result of Tenant's trash generated from the Kitchen, due to the fact that such trash is materially in excess of that generated by normal office use, then Tenant shall pay to Landlord, within thirty (30) days after billing and as Additional Rent, the actual and reasonable out-of-pocket cost of any such additional trash removal from the Office Unit (including, without limitation, the cost of the acquisition, operation and maintenance of any

equipment or other property which is acquired to facilitate such additional trash removal), all as reasonably determined by Landlord.

If Tenant fails to comply with the requirements set forth in this Exhibit C-2, without limitation of Landlord’s other remedies, and fails to cure the same within thirty (30) days after written notice from Landlord, Landlord shall have the right to terminate Tenant’s rights under this Exhibit C-2. The rights contained in this Exhibit C-2 shall be personal to Tenant and may only be exercised by Tenant (and not any other assignee, sublessee, or other transferee of original Tenant’s interest in this Lease, except for a Permitted Assignment or Permitted Sublease pursuant to Paragraph 13 of the Lease).

Tenant may retain a third party to operate the Kitchen (a “Third-Party Operator”). Any such Third- Party Operator must comply with all of the terms, covenants, conditions, and obligations on Tenant’s part to be observed and performed under this Lease and this Exhibit C-2 with respect to the use or occupancy of the Demised Premises, and any violation of any provision of this Lease by the Third-Party Operator shall be deemed to be a default by Tenant under such provision. Any such Third-Party Operator shall obtain such insurance as Landlord may reasonably require (consistent with the insurance requirements of landlords of comparable buildings for operators of similar commercial kitchens) and each of Tenant and Third-Party Operator shall indemnify, defend, and hold Landlord harmless in accordance with Tenant’s indemnity obligations set forth in Section 7.5 of the Lease with respect to the operation of the Kitchen. Third Party Operator shall have no recourse against Landlord whatsoever on account of any failure by Landlord to perform any of its obligations under this Lease or on account of any other matter. All notices required of Landlord under this Lease shall be forwarded only to Tenant in accordance with the terms of this Lease and in no event shall Landlord be required to send any notices to any Third-Party Operator. In no event shall any use of any portion of the Demised Premises by the Third-Party Operator release or relieve Tenant from any of its obligations under this Lease. The Third-Party Operator shall be a Tenant party, and Tenant shall be fully and primarily liable for all acts and omissions of such Third-Party Operator as fully and completely as if such Third-Party Operator was an employee of Tenant. In no event shall the occupancy of any portion of the Demised Premises by any Third-Party Operator be deemed to create a landlord/tenant relationship between Landlord and such Third-Party Operator or be deemed to vest in Third-Party Operator any right or interest in the Demised Premises or this Lease, and, in all instances, Tenant shall be considered the sole tenant under the Lease notwithstanding the occupancy of any portion of the Premises by any Third-Party Operator. Upon request from Landlord, Tenant shall provide to Landlord a copy of any agreement between Tenant and the Third-Party Operator and the insurance required to be maintained by Third-Party Operator prior to the Third-Party Operator being allowed access to the Demised Premises by Tenant. All such insurance shall name Landlord as an additional insured. No disputes between Tenant and the Third-Party Operator shall in any way affect the obligations of Tenant hereunder.
