THIS INDENTURE OF LEASE (this “Lease”) is hereby made and entered into on the Execution Date by and between Landlord and Tenant.

Each reference in this Lease to any of the terms and titles contained in any Exhibit attached to this Lease shall be deemed and construed to incorporate the data stated under that term or title in such Exhibit. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them as set forth in the Lease Summary Sheet which is attached hereto and incorporated herein by reference.

1. LEASE GRANT; TERM; APPURTENANT RIGHTS; EXCLUSIONS

1.1 Lease Grant. Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Premises upon and subject to terms and conditions of this Lease, for a term of years commencing on the Term Commencement Date and, unless earlier terminated or extended pursuant to the terms hereof, ending on the Expiration Date (the “Initial Term”; the Initial Term and any duly exercised Extension Terms are hereinafter collectively referred to as the “Term”). Landlord represents and warrants that: (i) except as listed on Exhibit 11 attached, there are no liens, encumbrances or other documents of record affecting the Property as of the Execution Date, and (ii) as of the Execution Date, business or professional office; research and development laboratories; and light manufacturing are permitted uses at the Property under applicable zoning and land use laws, codes and ordinances (without regard to any Alterations, including without limitation, Tenant’s Work).

1.2 Extension Terms.

(a) Provided Tenant then satisfies the following conditions (“Extension Option Conditions”): (i) that subleases for more than fifty percent (50%) of the Premises are not then in effect (excluding any Permitted Transfers) (the “Occupancy Condition”); (ii) Tenant has not been in default of its obligations for an aggregate of thirty (30) days or more prior to the date of the Extension Notice, and (iii) no Event of Default is then continuing (1) as of the date of the Extension Notice (hereinafter defined), and (2) at the commencement of the applicable Extension Term (hereinafter defined), Tenant shall have the option (“Extension Option”) to extend the Term for two (2) additional terms of five (5) years each (each, an “Extension Term”), commencing as of the expiration of the Initial Term, or the prior Extension Term, as the case may be. Tenant must exercise such option to extend by giving Landlord written notice (the “Extension Notice”) on or before the date (the “Extension Deadline”) that is twelve (12) months prior to the expiration of the then-current Term of this Lease, time being of the essence. Upon the timely giving of such notice, the Term shall be deemed extended upon all of the terms and conditions of this Lease, except that Base Rent during each Extension Term shall be calculated in accordance with this Section 1.2, Landlord shall have no obligation to construct or renovate the Premises pursuant to Section 3, and Tenant shall have one (1) fewer option to extend the Term. If Tenant fails to give timely notice, as aforesaid, Tenant shall have no further right to extend the Term. Notwithstanding the fact that Tenant’s proper and timely exercise of such option to extend the Term shall be self-executing, the parties shall promptly execute a lease amendment reflecting such Extension Term after Tenant exercises such option. The execution of such lease amendment shall not be deemed to waive any of the conditions to Tenant’s exercise of its rights under this Section 1.2.

(b) If Tenant then has an Extension Option remaining, Tenant has not previously given an Extension Notice to Landlord exercising such Extension Option, and Tenant then satisfies the Extension Option Conditions, Landlord shall, within fifteen (15) days of Landlord’s receipt of written request (“Tenant’s Request”) from Tenant (Tenant’s Request may be made no earlier than sixteen (16) months, and no later than thirteen (13) months prior to the expiration of the then current Term of the Lease), deliver to Tenant an offer (“Landlord’s Offer”) to lease the Premises to Tenant at a Base Rent based upon Landlord’s good faith estimate of the fair market rental value (as described in the following paragraph) of the Premises for the next following Extension Term. Tenant may accept Xxxxxxxx’s Offer by giving written notice to Landlord (“Acceptance Notice”) within fifteen (15) days after Xxxxxx’s

receipt of Landlord’s Offer. If Tenant timely gives an Acceptance Notice, then the Term of the Lease shall be extended for the next following Extension Term based upon the Base Rent set forth in Landlord’s Offer. If Tenant fails timely to give an Acceptance Notice, then Landlord’s Notice shall be void and without any further force or affect (including, without limitation, in the determination of the Extension Term Base Rent if Tenant timely exercises its Extension Option).

(c) If the Base Rent with respect to an Extension Term is not determined pursuant to Section 1.2(b) above, and Tenant timely and properly exercises its Extension Option with respect to such Extension Term, then the Base Rent during such Extension Term (the “Extension Term Base Rent”) shall be determined in accordance with the process described hereafter. Extension Term Base Rent shall be the fair market rental value of the Premises then demised to Tenant as of the commencement of the applicable Extension Term as determined in accordance with the process described below, for renewals of combination laboratory and office space in the City of Framingham, Massachusetts, of equivalent quality, size, utility and location, with the length of the Extension Term, the credit standing of Tenant and all other relevant factors to be taken into account, provided, however, any improvements paid for by Tenant shall not be taken into account. Within thirty (30) days after receipt of the Extension Notice or in any event within 30 days following any request from Tenant, Landlord shall deliver to Tenant written notice of its reasonable, good faith determination of the Extension Term Base Rent for the applicable Extension Term (“Landlord’s Rent Estimate”). Tenant shall, within thirty (30) days after receipt of such notice (or, if received prior the Extension Deadline, no later than the timely giving of its Extension Notice), notify Landlord in writing whether Tenant accepts or rejects Landlord’s determination of the Extension Term Base Rent (“Tenant’s Response Notice”). If Tenant fails timely to deliver Tenant’s Response Notice and has timely given its Extension Notice, Landlord’s determination of the Extension Term Base Rent shall be binding on Tenant.

(d) If and only if Tenant’s Response Notice and Extension Notice is timely delivered to Landlord and indicates both that Tenant rejects Landlord’s determination of the Extension Term Base Rent and desires to submit the matter to arbitration, then the Extension Term Base Rent shall be determined in accordance with the procedure set forth in this Section 1.2(c). In such event, within ten (10) days after receipt by Landlord of Tenant’s Response Notice indicating Tenant’s desire to submit the determination of the Extension Term Base Rent to arbitration, Tenant and Landlord shall each notify the other, in writing, of their respective selections of a commercial real estate broker or appraiser (respectively, “Landlord’s Appraiser” and “Tenant’s Appraiser”). Landlord’s Appraiser and Tenant’s Appraiser shall then jointly select a third appraiser (the “Third Appraiser”) within ten (10) days of their appointment. All of the brokers/appraisers selected shall be individuals with at least ten (10) consecutive years’ commercial experience in the area in which the Premises are located, and in the case of appraisers, shall be members of the Appraisal Institute (M.A.I.). The Third Appraiser shall not have acted in any capacity for either Landlord or Tenant within ten (10) years of his or her selection. The three appraisers shall determine the Extension Term Base Rent in accordance with the requirements and criteria set forth in Section 1.2(b) above, employing the method commonly known as Baseball Arbitration, whereby Landlord’s Appraiser and Tenant’s Appraiser each sets forth its determination of the Extension Term Base Rent as defined above, and the Third Appraiser must select one or the other (it being understood that the Third Appraiser shall be expressly prohibited from selecting a compromise figure). Landlord’s Appraiser and Xxxxxx’s Appraiser shall deliver their determinations of the Extension Term Base Rent to the Third Appraiser within five (5) days of the appointment of the Third Appraiser and the Third Appraiser shall render his or her decision within ten (10) days after receipt of both of the other two determinations of the Extension Term Base Rent. The Third Appraiser’s decision shall be binding on both Landlord and Tenant. Each party shall bear the cost of its own appraiser and the cost of the Third Appraiser shall be paid by the party whose determination is not selected.

1.3 Appurtenant Rights.

(a) Common Areas. Subject to the terms of this Lease and the Rules and

Regulations (hereinafter defined), Tenant shall have, as appurtenant to the Premises, rights to use in common with others entitled thereto, the following areas (such areas are hereinafter referred to as the “Common Areas”): (i) the common hallway of the Building serving the Premises (the “Common Hallway”), (ii) common walkways and driveways necessary for access to the Building, (iii) risers, shafts, chases, and conduits designated by Landlord for use by tenants and/or other occupants, (iv) parking areas as further described in the immediately following paragraph, (v) areas of the Building and on the rooftop of the Building necessary for access to the Rooftop Premises and/or the Common Hallway, (vi) common electrical and service facilities; and (vii) other areas and facilities designated by Landlord from time to time for the common use of tenants of the Building, if any; and except as provided under common law or as expressly set forth in this Lease, no other appurtenant rights or easements.

(b) Parking. During the Term, Landlord shall, subject to the terms hereof, make available up to one hundred ninety (190) parking spaces (i.e., 3 parking spaces per 1,000 rentable square feet of the Premises) for Tenant’s use in the parking area serving the Building at no charge; provided that the foregoing shall not be deemed to exclude costs associated with the parking areas from Operating Costs or Taxes to the extent not otherwise excluded under Section 5.2(b). The number of parking spaces in the parking areas allocated to Tenant, as modified pursuant to this Lease or as otherwise permitted by Landlord, are hereinafter referred to as the “Parking Spaces.” Tenant shall have no right to hypothecate or encumber the Parking Spaces, and shall not sublet, assign, or otherwise transfer the Parking Spaces, other than to employees of Tenant occupying the Premises or a transferee pursuant to an approved Transfer (or Transfer not requiring approval) under Section 13 of this Lease. Said Parking Spaces will be on an unassigned, non-reserved basis. Landlord shall not grant any other tenant in the Building the right to reserved or assigned parking spaces without granting Tenant an equivalent amount in proportion to the respective tenants’ rentable square footage in the Building. All of the Parking Spaces shall be subject to such reasonable Rules and Regulations as may be in effect for the use of the parking areas from time to time.

Notwithstanding anything to the contrary contained herein, (i) Landlord shall have the right, during the performance of Landlord’s restoration obligations set forth in Section 15 below, to temporarily relocate all or any portion of the Parking Spaces to the parking areas located within a reasonable vicinity of the Building, and (ii) Landlord shall have the one-time right, upon at least six (6) months’ written notice to Tenant but not prior to the third anniversary of the Term Commencement Date, in connection with Future Development (as defined in Section 2.2), to temporarily relocate all or any portion of the Parking Spaces located in the Common Parking area to the parking areas located within a radius of 0.33 miles’ walking distance from the main entrance to the Premises for a period of no more than twelve (12) months. Landlord shall use reasonable efforts to stage any Future Development in a manner that minimizes the duration of such temporary relocation. Notwithstanding the foregoing, in the event Landlord exercises its right to relocate any Parking Spaces under clause (ii) above, Landlord expressly agrees that it will not relocate thirty-five (35) parking spaces from the site that will be dedicated for use by Tenant during the period of time when the balance of Tenant’s Parking Spaces are relocated from the Property.

(c) Rooftop Premises. During the Term, Tenant shall have the right to use the portion of the rooftop of the Building shown on the plan attached hereto as Exhibit 1C (the “Rooftop Premises”) for the installation and operation of mechanical and communications equipment (A) serving only the Premises, (B) approved by Landlord, and (C) purchased and installed by Tenant in accordance with the terms of this Lease (any equipment installed within the Rooftop Premises, as the same may be modified, altered or replaced during the Term, is collectively referred to herein as “Tenant’s Rooftop Equipment”). Landlord’s approval of such equipment shall not be unreasonably withheld, conditioned or delayed. Landlord acknowledges that the equipment described on Exhibit 1C attached hereto has been approved by Landlord (subject to the provisions of Sections 3 (if applicable) and 11 governing the installation thereof. Tenant shall operate Tenant’s Rooftop Equipment in a manner that does not interfere

with (x) any make-up air installations to the extent installed prior to the date of installation of Tenant’s Rooftop Equipment, (y) any other tenant’s rooftop equipment to the extent installed prior to the date of installation of Tenant’s Rooftop Equipment or (z) base building equipment operated by Landlord to the extent installed prior to the date of installation of Tenant’s Rooftop Equipment. Any installation of Tenant’s Rooftop Equipment (i) will not affect the structural integrity of the Building or impact the roof or the roof membrane in any manner; (ii) shall be adequately screened in accordance with Landlord’s screening standards as further described on Exhibit 13 attached, and in compliance with the City of Framingham zoning requirements so as to minimize the visibility of such equipment; and (iii) shall be adequately sound-proofed to meet all requirements of Legal Requirements. Tenant shall not install or operate Tenant’s Rooftop Equipment until Tenant has obtained and submitted to Landlord copies of all required governmental permits, licenses, and authorizations necessary for the installation and operation thereof. In addition, Tenant shall comply with all reasonable construction Rules and Regulations promulgated by Landlord in connection with the installation, maintenance and operation of Tenant’s Rooftop Equipment. Landlord shall have no obligation to provide any services including, without limitation, electric current or gas service, to the Rooftop Premises or to Tenant’s Rooftop Equipment, it being understood and agreed that Tenant shall be responsible for constructing any risers, shafts, chases, or conduits necessary to connect the necessary services from the Premises to Tenant’s Rooftop Equipment. Tenant shall be responsible for repairing and maintaining Tenant’s Rooftop Equipment at Tenant’ sole cost and, subject to the provisions of Section 14.5, the cost of repairing any damage to the Building, or the cost of any necessary improvements to the Building, caused by or as a result of the installation, replacement and/or removal of Tenant’s Rooftop Equipment. Landlord makes no warranties or representations to Tenant as to the suitability of the Rooftop Premises for the installation and operation of Tenant’s Rooftop Equipment. In the event that at any time during the Term, the operation and/or periodic testing of any other rooftop equipment installed after Tenant’s Rooftop Equipment interferes with Tenant’s make-up air installations or the operation of the Tenant’s Rooftop Equipment or the business operations of Tenant, then Landlord shall, upon notice from Tenant, cause (if Building rooftop equipment) or use commercially reasonable efforts to cause the operator of the interfering equipment (if other tenant’s rooftop equipment) to cease such testing or interference, as applicable. In the event that at any time during the Term, Landlord determines, in its bona fide and good faith business judgment, that the operation and/or periodic testing of Tenant’s Rooftop Equipment unreasonably interferes with the operation of the Building or the business operations of any of the occupants of the Building (other than interference with rooftop equipment installed after the installation of Tenant’s Rooftop Equipment), recognizing the use of the Building for the Permitted Uses, then Tenant shall, upon notice from Landlord, cease using such interfering equipment and cause all further testing of Tenant’s Rooftop Equipment to occur after normal business hours (hereinafter defined). From and after the Execution Date, Landlord shall include substantially similar provisions governing rooftop equipment in any other leases at the Building (giving priority to previously installed rooftop equipment vis-à-vis subsequently installed rooftop equipment) and shall not enforce such provisions in a discriminatory manner.

(d) On-Site Generator. Subject to Legal Requirements and Landlord’s prior written approval of plans and specifications therefor, Tenant may install, operate and maintain, in one of the locations shown on Exhibit 1B attached or another location mutually agreed to by the parties (the “Generator Location”), an up to 1,000 KW emergency generator (the “Emergency Back-up Equipment”) at Tenant’s sole cost and expense; provided, however, that if any Emergency Back-up Equipment is located in the parking areas, any parking spaces used/lost as a result thereof shall be included in Tenant’s parking allotment as described in Section 1.3(b) above. Landlord shall have no obligation to provide any services including, without limitation, electric current or gas service, to the Emergency Back-up Equipment, provided, however, subject to Legal Requirements and Landlord’s prior written approval of plans and specifications therefor, Tenant may also install, maintain and operate necessary utility connections between the Emergency Back-up Equipment and the Premises (which utility connections shall be deemed part of the Emergency Back-up Equipment). Landlord may, in its sole and absolute discretion, require Tenant, at Landlord’s cost, to relocate any or all of the Emergency Back-up Equipment to a location with comparable functionality, which relocation shall be performed by Tenant

within a reasonable period following such request (taking into account any reasonable time necessary to obtain permits and approvals for such work, Tenant hereby agreeing to use diligent good faith efforts to obtain the same and to promptly commence and prosecute to completion such relocation thereafter). Landlord agrees to require such relocation no more than once during the Term (provided that such limitation shall not apply to temporary relocations required in connection with any required maintenance, repair or replacement by Landlord). Landlord’s approval of the Emergency Back-up Equipment shall not be unreasonably withheld, conditioned or delayed. Tenant shall be responsible for the cost of repairing and maintaining the Emergency Back-up Equipment in good order, condition and repair and in compliance with Legal Requirements and, subject to the provisions of Section 14.5, for the cost of repairing any damage to the Property, or the cost of any necessary improvements to the Property, caused by or as a result of the installation, replacement and/or removal of the Emergency Back-up Equipment. Landlord makes no warranties or representations to Tenant as to the suitability of the Generator Location for the installation and operation of the Emergency Back-up Equipment. Tenant shall not install or operate the Emergency Back-up Equipment until Tenant has obtained and submitted to Landlord copies of all required governmental permits, licenses, and authorizations necessary for the installation and operation thereof. In addition, Tenant shall comply with all reasonable Rules and Regulations in connection with the installation, maintenance and operation of the Emergency Back-up Equipment.

(e) Outdoor Patio. Subject to the Rules and Regulations and the provisions of this Lease, Landlord agrees that Tenant shall have, as appurtenant to the Premises, the non-exclusive right to use the area adjacent to the Building designated by Landlord, as more particularly shown on the plan attached hereto as “Outdoor Patio Location” on Exhibit 1B attached hereto (the “Outside Seating Area”) throughout the Term hereof. In no event shall Landlord permit smoking or vaping within 20 feet of the Building or any Tenant entrance to the Building. Notwithstanding anything to the contrary contained herein, Landlord shall have the right, upon as much notice as is practicable under the circumstances and in any event no less than forty-eight (48) hours (except that no notice shall be required in the event of an emergency) to close all or any portion of the Outside Seating Area in connection with the performance of repairs, maintenance, and/or construction (if such closure cannot be reasonably avoided in connection with such repairs, maintenance and/or construction). Landlord shall install and maintain, at its sole cost and expense, all desired furniture, equipment and lighting (collectively, “Furniture”) in the Outside Seating Area.

(f) Nitrogen Tanks. Subject to Legal Requirements and Landlord’s prior written approval of plans and specifications therefor, which approval shall not be unreasonable withheld, Tenant may install, operate and maintain, in one or more of the locations outside of the Building, as shown on Exhibit 1B attached or another location or locations mutually agreed to by the parties (the “Nitrogen Tank Premises”), one or more nitrogen tanks necessary to serve Tenant’s use of the Premises (collectively, the “Nitrogen Tanks”) at Tenant’s sole cost and expense; provided, however, that: (i) if the Nitrogen Tanks are located in the parking areas, any parking spaces used/lost as a result thereof shall be included in Tenant’s parking allotment as described in Section 1.3(b) above, and (ii) if Tenant desires to install more than one Nitrogen Tank, then Tenant’s right to do so shall be subject to Landlord’s prior written approval. Landlord agrees that it will not unreasonably withhold its approval to install Nitrogen Tanks in excess of one Nitrogen Tank, provided that it shall be reasonable for Landlord to withhold such approval if, in Landlord’s bona fide business judgment, such installation shall preclude another tenant of the Building from installing nitrogen tanks which are necessary for its operations in the Building. Tenant’s plans for the Nitrogen Tanks shall include a secondary containment system to protect against and contain any release of Hazardous Materials. Tenant shall inspect such secondary containment system on a periodic basis that is sufficient to avoid leaks. Landlord shall have no obligation to provide any services including, without limitation, electric current or gas service, to the Nitrogen Tanks, provided, however, subject to Legal Requirements and Landlord’s prior written approval of plans and specifications therefor, Tenant may also install, maintain and operate necessary utility connections between the Nitrogen Tanks and the Premises (which utility connections shall be deemed part of the Nitrogen Tanks). Landlord may, in its sole and absolute discretion, require Tenant, at Xxxxxxxx’s cost, to relocate the Nitrogen Tanks

to a location with comparable functionality, which relocation shall be performed by Tenant within a reasonable period following such request (taking into account any reasonable time necessary to obtain permits and approvals for such work, Tenant hereby agreeing to use diligent good faith efforts to obtain the same and to promptly commence and prosecute to completion such relocation thereafter). Landlord agrees to require such relocation no more than once during the Term (provided that such limitation shall not apply to temporary relocations required in connection with any required maintenance, repair or replacement by Landlord). Landlord’s approval of the Nitrogen Tanks shall not be unreasonably withheld, conditioned or delayed and shall not prohibit use of a tank sufficiently large to serve Tenant’s operations in the Premises. Tenant shall be responsible for the cost of repairing and maintaining the Nitrogen Tanks in good order, condition and repair and in compliance with Legal Requirements and, subject to the provisions of Section 14.5, for the cost of repairing any damage to the Property, or the cost of any necessary improvements to the Property, caused by or as a result of the installation, replacement and/or removal of the Nitrogen Tanks. Landlord makes no warranties or representations to Tenant as to the suitability of the Nitrogen Premises for the installation and operation of the Nitrogen Tanks. Tenant shall not install or operate the Nitrogen Tanks until Tenant has obtained and submitted to Landlord copies of all required governmental permits, licenses, and authorizations necessary for the installation and operation thereof. In addition, Tenant shall comply with all reasonable Rules and Regulations in connection with the installation, maintenance and operation of the Nitrogen Tanks.

1.4 Tenant’s Access.

(a) From and after the Term Commencement Date and until the end of the Term, Tenant shall have access to the Premises twenty-four (24) hours a day, seven (7) days a week, subject to Legal Requirements, the Rules and Regulations, the terms of this Lease and matters of record as of the Execution Date.

(b) Upon at least two (2) business days’ notice, Tenant shall have the right to access the Premises with a Landlord representative present, at Tenant’s sole risk, after the Execution Date but prior to the Term Commencement Date for taking measurements and other non-construction activities to facilitate space planning, provided such access does not materially interfere with the preparation for or performance of Landlord’s Work (hereinafter defined). Tenant shall, prior to the first entry to the Premises pursuant to this Section 1.4(b), provide Landlord with certificates of insurance evidencing that the insurance required in Section 14 hereof is in full force and effect and covering any person or entity entering the Building. Tenant shall defend, indemnify and hold the Landlord Parties (hereinafter defined) harmless from and against any and all Claims (hereinafter defined) for injury to persons or property to the extent resulting from or relating to Tenant’s access to the Premises prior to the Term Commencement Date as provided under this Section 1.4(b). Tenant shall coordinate any access to the Premises prior to the Term Commencement Date with Xxxxxxxx’s property manager.

1.5 Notice of Lease. Neither party shall record this Lease, but each of the parties hereto agrees to join in the execution, in recordable form, of a statutory notice of lease in substantially the form attached hereto as Exhibit 9 in which shall be stated the Term Commencement Date, the Additional Rent Commencement Date, the Base Rent Commencement Date, the number and length of the Extension Terms and the Expiration Date, which notice of lease may be recorded by Xxxxxx with the Middlesex South Registry of Deeds and/or filed with the Registry District of the Land Court, as appropriate (collectively, the “Registry”) at Tenant’s sole cost and expense (provided, however, that Landlord shall provide such evidence of authority as is reasonably required for the filing of the notice of lease at Landlord’s sole cost and expense). If a notice of lease was previously recorded with the Registry, upon the expiration or earlier termination of this Lease, Landlord shall deliver to Tenant a notice of termination of lease and Tenant shall promptly execute and deliver the same to Landlord for Landlord’s execution and recordation with the Registry, which obligation shall survive the expiration or earlier termination of the Lease.

1.6 Exclusions. The following are expressly excluded from the Premises and reserved to Landlord: all the perimeter walls of the Premises (except the inner surfaces thereof), [Subject to further review of Landlords plans:] the Common Areas, and any space in or adjacent to the Premises used for shafts, stacks, pipes, conduits, wires and appurtenant fixtures, fan rooms, ducts, electric or other utilities, sinks and other facilities serving portions of the Building other than the Premises, and the use of all of the foregoing, except as expressly permitted pursuant to Section 1.3(a) above.

2. RIGHTS RESERVED TO LANDLORD

2.1 Additions and Alterations. Landlord reserves the right, at any time and from time to time, to make such changes, alterations, additions, improvements, repairs or replacements in or to the Property (including the Premises but, with respect to the Premises, only for purposes of repairs, maintenance, replacements and other rights expressly reserved to Landlord hereunder) and the fixtures and equipment therein, as well as in or to the street entrances and/or the Common Areas, as it may deem necessary or desirable, provided, however, that there be no material obstruction of access to, or interference (other than de minimis interference consistent with the undertaking of ordinary alterations, repairs and maintenance in a first class office and laboratory and GMP manufacturing buildings) with the use and enjoyment of, the Premises and Tenant’s express appurtenant rights in the Property described herein (subject to the provisions of Section 1.3, above) and such changes are consistent with an occupied first-class office and laboratory and GMP manufacturing building in the area. Subject to the foregoing, and subject to Section 1.3(b) above, Landlord expressly reserves the right to temporarily close all, or any portion, of the Common Areas for the purpose of making repairs or changes thereto, provided that the duration of such closure will be limited to a reasonable period of time in light of the nature of the repairs or changes being made thereto, consistent with an occupied first-class office and laboratory building. In no event shall Landlord exercise any of its rights under this Section 2.1 without giving Tenant reasonable prior notice of the same. In no event shall Landlord be permitted pursuant to this Section 2.1 or otherwise to construct additional leasable areas above the Premises.

2.2 Additions to the Property. Landlord may at any time or from time to time (but not prior to the third anniversary of the Term Commencement Date) construct additional buildings and related site improvements (collectively, the “Future Development”) on the Property and/or on property (“Adjacent Property”) adjacent to the Property, provided that Future Development shall not require use of the Premises or any portion of the Building connected to or serving the Premises. In addition, but subject to Section 1.3 above, Landlord may change the location or arrangement of any improvement outside the Building in or on the Property or all or any part of the Common Areas, or add or deduct any land to or from the Property. There shall be no increase in Tenant’s obligations or interference with Xxxxxx’s rights under this Lease in connection with the exercise of the foregoing reserved rights (other than de minimis impacts not inconsistent with occupied first class office and laboratory buildings). Xxxxxxxx’s plans and specifications for any Future Development shall be subject to Tenant’s prior written approval, which approval shall not be unreasonably withheld, conditioned, or delayed. Tenant shall respond in writing to any request from Landlord for its approval of Xxxxxxxx’s plans and specifications for any Future Development, as soon as reasonably possible, but in any event within thirty (30) days of Tenant’s receipt of such request and plans and specifications.

In connection with any Future Development, in no event shall Tenant be denied reasonable access to the parking required under Section 1.3(b), as such parking may be relocated pursuant thereto. Landlord agrees, in connection with any such development or redevelopment, to utilize all commercially reasonable efforts to mitigate the impacts of earthwork and other construction activities on Tenant’s business operations consistent with standards for occupied first-class suburban office, laboratory and research and development projects. Landlord shall prepare and deliver a reasonable construction mitigation plan after consulting with Tenant, which plan shall incorporate such measures as are reasonably required to maintain and operate Tenant’s business in the Premises in a manner consistent with first class office and laboratory use. Tenant shall have the right to approve such mitigation plan, such approval not to be

unreasonably withheld, conditioned or delayed (and any objections to such plan must be specifically described in writing so that Landlord may respond to them). Landlord will cause all blasting, pile driving or other work resulting in vibrations within the Premises in excess of customary levels of activity in an occupied first class office and laboratory building to take place during normal business hours unless required by Legal Requirements (including without limitation the City of Framingham), Landlord hereby agreeing not to request that the City or any other governmental authority require that such blasting occur at any particular time) and such work must be scheduled with at least thirty (30) days’ prior written notice to Tenant.

Landlord and Tenant each hereby acknowledges and agrees that, in connection with Future Development, (a) Landlord shall have the right to subject the Land, Adjacent Property (if applicable), and the improvements located now or in the future located thereon to a commercial condominium regime (“Condominium”) on terms and conditions consistent with first-class office and laboratory parks in the Framingham area, in which the Building shall be a single unit; (b) upon Landlord’s request in connection with the recording of the Master Deed for the Condominium and the Unit Deed for the Building, Tenant shall execute a reasonable instrument in recordable form making this Lease subject and subordinate to the Master Deed and other documents evidencing the Condominium (collectively, the “Condo Documents”) provided that such Condo Documents continue to provide Tenant with all of the rights and obligations contained in this Lease (e.g., the appurtenant right to use all Common Areas) and the Condo Documents comply with the provisions of this Section 2.2; (c) Landlord shall have the right to enter into, and subject the Property to the terms and conditions of, a reciprocal easement agreement with any one or more of the neighboring property owners in order to create a commercial campus-like setting (“REA”) provided that such REA continues to provide Tenant with all of the rights and obligations contained in this Lease as of the Execution Date (e.g., the appurtenant right to use all Common Areas) and the REA complies with the provisions of this Section 2.2; (d) Landlord shall submit to Tenant for Tenant’s approval drafts of the Condo Documents and the REA (and any amendments thereto) prior to their execution; (e) Tenant shall have the right to notify Landlord within twenty (20) days after receipt of the draft Condo Documents and/or REA (or any amendments thereto) of Tenant’s disapproval thereof, but only to the extent such draft(s) (i) adversely affect Tenant’s use of, or access to, the Premises, the Building systems or the Rooftop Premises in more than a de minimis manner, (ii) adversely affect in more than a de minimis manner the operation of Tenant’s business from the Premises in accordance with the terms of this Lease, or Tenant’s rights under and pursuant to the terms of this Lease, including without limitation Tenant’s rights with respect to the Common Areas, and/or (iii) result in any increase in Tenant’s payment or other obligations under this Lease in more than a de minimis manner; (f) upon Xxxxxxxx’s request in connection with the recording of the REA, Tenant shall execute a commercially reasonable instrument in recordable form making this Lease subject and subordinate to the REA; (g) Landlord shall have the right to subdivide the Property so long as Tenant continues to have all of the rights and obligations contained in this Lease (e.g. the appurtenant right to use all Common Areas); and (h) Tenant shall execute such reasonable documents (which may be in recordable form) evidencing the foregoing promptly upon Xxxxxxxx’s request. Landlord shall reimburse Tenant for the reasonable out-of-pocket costs incurred by Xxxxxx, if any, to review and comment on any documents or instruments presented to Tenant pursuant to this paragraph.

2.3 Name and Address of Building. Landlord reserves the right at any time and from time to time to change the name or address of the Building and/or the Property, provided Landlord gives Tenant at least three (3) months’ prior written notice thereof. Notwithstanding the foregoing to the contrary, so long as Tenant’s Share is at least 50%, Landlord shall not voluntarily change the address of the Building without Tenant’s prior written consent, not to be unreasonably withheld, conditioned or delayed. Within thirty (30) days after receipt of a reasonably detailed invoice, Landlord shall reimburse Tenant for up to $2,500 of the reasonable out-of-pocket costs incurred by Tenant in connection with any such change. Landlord shall not name the Building after any tenant or occupant and any such name shall be consistent with first-class office and laboratory buildings in the area.

2.4 Landlord’s Access.

(a) Subject to the terms hereof, Tenant shall (i) upon as much advance notice as is practical under the circumstances, and in any event at least twenty-four (24) hours’ prior written notice (except that no notice shall be required in emergency situations), permit Landlord and any holder of a Mortgage (hereinafter defined) (each such holder, a “Mortgagee”), and their agents, representatives, employees and contractors, to have reasonable access to the Premises at all reasonable hours for the purposes of inspection, making repairs, replacements or improvements in or to the Premises or the Building or equipment therein (including, without limitation, sanitary, electrical, heating, air conditioning or other systems), complying with all applicable laws, ordinances, rules, regulations, statutes, by-laws, court decisions and orders and requirements of all public authorities (collectively, “Legal Requirements”), or exercising any right reserved to Landlord under this Lease requiring such entry (but expressly excluding the right to store within the Premises any materials, tools and equipment); (ii) permit Landlord and its agents and employees, at reasonable times, upon reasonable advance notice, to show the Premises during normal business hours (i.e. Monday — Friday 8 A.M. - 6 P.M., excluding holidays) to any prospective Mortgagee or purchaser of the Building and/or the Property or of the interest of Landlord therein, and, during the last twelve (12) months of the Term, prospective tenants; (iii) upon reasonable prior written notice from Landlord, permit Landlord and its agents, at Landlord’s sole cost and expense, to perform environmental audits, environmental site investigations and environmental site assessments (“Site Assessments”) in, on, under and at the Premises and the Land, it being understood that Landlord shall repair any damage arising as a result of the Site Assessments, and such Site Assessments may include both above and below the ground testing and such other tests as may be necessary or appropriate to conduct the Site Assessments, Landlord hereby agreeing to provide Tenant with a copy of the resulting Site Assessment reports when issued in its final form, and (iv) to the extent that it is necessary to enter the Premises in order to access any area that serves any portion of the Building outside the Premises, then Tenant shall, upon as much advance notice as is practical under the circumstances, and in any event at least twenty-four (24) hours’ prior written notice (except that no notice shall be required in emergency situations), permit contractors engaged by other occupants of the Building to pass through the Premises in order to access such areas but only if accompanied by a representative of Landlord.

(b) Except in emergency situations, anyone who has access to any portion of the Premises pursuant to this Section 2.4 after Tenant has first commenced to use the Premises for the Permitted Uses may, at Tenant’s election, be subject to Tenant’s reasonable security measures and protocols, which may include requiring that any party accessing the Premises under Section 2.4(a)(ii) and (iv) execute a commercially reasonable confidentiality agreement, requiring the wearing of an ID badge, and obligating visitors to comply with reasonable protocols so as protect confidential information contained within the Premises and comply with Tenant’s reasonable health and safety procedures. No measures undertaken by Tenant with respect to Landlord’s right to enter the Premises to maintain compliance of Tenant’s activities within the Premises with applicable Laws, and advisory guidance governing Tenant’s research, development, or manufacturing process at the Premises, shall be deemed unreasonable. Except in the event of an emergency threatening personal injury or damage to property or a violation of any Legal Requirement, and except as otherwise approved by Tenant, any entry in the Premises must be done in the presence of a representative of Tenant so long as Tenant makes such representative available in a reasonable manner. Tenant may prohibit access pursuant to this Section 2.4 to (i) Tenant’s GMP manufacturing facility and (ii) certain areas of the Premises (collectively, “Secure Areas”) reasonably identified by Tenant in a prior written notice to Landlord from time to time, which notice shall set forth the reasonable basis on which Tenant has determined that access must be prohibited to such areas in non-emergency situations. In no event shall Landlord be deemed to be in default hereunder, nor shall Landlord have any liability hereunder, to the extent that Landlord is prevented from performing any of its obligations as a result of its inability to access the Secure Areas in non-emergency situations. Notwithstanding the foregoing, in case of emergency, Landlord may enter any part of the Premises (including without limitation the Secure Areas) without prior notice or a Tenant’s

representative; provided that Landlord provides Tenant with notice of such entry as soon as reasonably possible thereafter and Landlord takes reasonable precautions to protect the health and safety of its entrants. Nothing in this paragraph will be construed as permitting Tenant to prohibit such access to any portion of the Premises other than Secure Areas. Upon Xxxxxx’s request, Landlord shall require any Landlord or property manager personnel needing access to the Premises to undergo training in Tenant’s health and safety protocols.

(c) Except in the event of an emergency, (i) Landlord shall schedule any of such access under this Section 2.4 with Tenant in advance; and (ii) to the extent such access shall, in Tenant’s reasonable judgment, be likely to cause material interference with Tenant’s business operations, Landlord shall, at Tenant’s request, schedule any such entry pursuant to Sections 2.4(a)(i) and (iii) after normal business hours.

(d) Except to the extent arising as a result of the negligence or willful misconduct of the Tenant Parties, Landlord shall, subject to Section 14.5 below, defend, indemnify and hold Tenant harmless from and against any and all Claims (as defined below) resulting from or relating to access to the Premises as provided under this Section 2.4.

(e) Any provision of this Lease that requires or gives Landlord the right to enter the Premises during the Term shall be governed by the provisions of this Section 2.4 and this Section 2.

2.5 Pipes, Ducts and Conduits. Tenant shall permit Landlord to erect, use, maintain and relocate pipes, ducts and conduits in and through the Premises (other than those exclusively serving Tenant), provided the same are located to the exterior of any interior walls, above any drop ceilings or otherwise the lowest level of the roof structure, or below the floor, do not reduce the floor area or materially adversely affect the appearance thereof.

2.6 Minimize Interference. Except in the event of an emergency, Landlord shall use commercially reasonable efforts to minimize any interference with Xxxxxx’s business operations and use and occupancy of the Premises in connection with the exercise any of the foregoing rights under this Section 2.

3. CONDITION OF PREMISES; CONSTRUCTION.

3.1 Condition of Premises. Landlord shall deliver the Premises to Tenant on the Term Commencement Date: (a) broom clean, (b) free of all personal property and occupants, (c) in compliance with Legal Requirements, (d) free of Hazardous Materials in excess of Reportable Concentrations and Reportable Quantities (as defined in Environmental Laws (hereinafter defined)), and (e) with the Initial Phase of Landlord’s Work Substantially Complete (as said terms are hereinafter defined). On or before the Base Building Certificate of Occupancy Date (hereinafter defined), the structural elements of the Building, the electric service, plumbing and life/safety systems, and other systems serving the Building in general, the Common Areas, the roof and roof system of the Building, the exterior wall system, and the exterior windows of the Premises shall be weather tight and in good repair and working order (such condition of the systems and portions of the Building and the Common Areas being referred to herein as “Satisfactory Building Condition”). Subject to the foregoing, and subject to Landlord’s obligation to perform Landlord’s Work, Tenant acknowledges and agrees that Tenant is leasing the Premises in their “AS IS,” “WHERE IS” physical condition and with all faults on the Execution Date, without representations or warranties, express or implied, in fact or by law, of any kind.

3.2 Landlord’s Work.

(a) Definition of Landlord’s Work. Landlord shall perform Landlord’s Work (as hereinafter defined). “Landlord’s Work” shall consist of Landlord’s Base Building Work and Landlord’s Tenant Improvement Work (as said terms are hereinafter defined). The “Initial Phase of Landlord’s Work” consists of the Initial Phase of Landlord’s Base Building Work, as hereinafter defined, and Landlord’s Tenant Improvement Work, as hereinafter defined.

(i) “Landlord’s Base Building Work” shall mean the work shown on the Landlord Work Plans attached hereto as Exhibit 4A (“Design Development Plans”), as such work shall be further described in complete, coordinated construction documents (“Construction Documents”) which are consistent with the Design Development Plans and prepared by Landlord and approved by Tenant in accordance with Section 3.2(b) below.

(x) Cost of Landlord’s Base Building Work. Landlord’s Base Building Work shall be performed at Landlord’s sole cost and expense, except to the extent of actual, net out-of-pocket increases in cost arising from delays due to any act or (where Tenant has a duty to act) omission by Xxxxxx and/or Tenant’s agents, servants, employees, consultants, contractors, subcontractors, licensees and/or subtenants (collectively with the Tenant, the “Tenant Parties”) that causes an actual delay in the performance of Landlord’s Work (“Tenant Delays”) (provided that no Tenant Delay shall be deemed to occur under this Lease until Landlord gives Tenant written notice of the event giving rise to such claimed Xxxxxx Xxxxx and a reasonable description of the same). Landlord shall: (1) give Tenant written notice of Landlord’s good faith estimate of costs arising from Tenant Delays, based upon input from Xxxxxxxx’s general contractor and design consultants, at the time that Landlord notifies Tenant of the applicable Tenant Delay, (2) use reasonable efforts to mitigate any such increases in the cost of Landlord’s Base Building Work, and (3) following completion of the Base Building Work, provide Tenant with reasonable evidence of the actual costs incurred by Landlord on account of such Tenant Delay prior to invoicing Tenant for such costs.

(y) Phases of Landlord’s Base Building Work. Landlord’s Base Building Work shall be completed within three phases, each as hereinafter defined: (1) the Initial Phase of Landlord’s Base Building Work, (2) the Balance of Landlord’s Base Building Work, and (3) the Post-Certificate of Occupancy Phase of Landlord’s Base Building Work. The “Initial Phase of Landlord’s Base Building Work” shall consist of all of Landlord’s Base Building Work other than the Balance of Landlord’s Base Building Work and the Post-Certificate of Occupancy Phase of Landlord’s Base Building Work. The “Balance of Landlord’s Base Building Work” shall be the work listed on Exhibit 4B. The “Post-Certificate of Occupancy Phase of Landlord’s Base Building Work” shall be the work listed on Exhibit 4C.

(ii) “Landlord’s Tenant Improvement Work” shall be as described in the Design Development Documents and on Exhibit 4D, and will be shown in the Construction Documents. Tenant shall be responsible for the entire cost incurred by Landlord with respect to Landlord’s Tenant Improvement Work (“Total Cost of Landlord’s Tenant Improvement Work”), as reasonably evidenced to Tenant. The Total Cost of Landlord’s Tenant Improvement Work consists of the sum of: (x) Hard Cost of Landlord’s Tenant Improvement Work, as hereinafter

defined, plus (y) any engineering and design fees incurred by Landlord in connection with the design and construction administration of Landlord’s Tenant Improvement Work (“Soft Cost of Landlord’s Tenant Improvement Work”). The parties estimate that the Total Cost of Landlord’s Tenant Improvement Work is $1,057,618.00, as set forth on the Estimated Preliminary Budget for Landlord’s Tenant Improvement Work, attached hereto as Exhibit 14.

(iii) Payment Procedures for the Total Cost of Landlord’s Tenant Improvement Work.

a. Soft Cost of Landlord’s Tenant Improvement Work. Tenant shall be responsible for 100% of the Soft Cost of Landlord’s Tenant Improvement Work, subject to Landlord’s Contribution in accordance with Section 3.4(b).

b. Hard Cost of Landlord’s Tenant Improvement Work. Tenant shall be responsible for 100% of the Hard Cost of Landlord’s Tenant Improvement Work, subject to Landlord’s Contribution in accordance with Section 3.4(b). The parties acknowledge that Xxxxxxxx’s Tenant Improvement Work will be performed by the contractor (“Landlord’s Contractor”) which Landlord engages to perform Landlord’s Work. Accordingly, Xxxxxxxx’s Tenant Improvement Work will be performed by subcontractors (“Landlord’s Tenant Improvement Work Subcontractors”) who will also be performing portions of Landlord’s Base Building Work. Therefore, Tenant shall pay Tenant’s Hard Cost Share, as hereinafter defined, of each requisition from Landlord’s Contractor which includes payment to Landlord’s Contractor on account of the work performed by Xxxxxxxx’s Tenant Improvement Work Subcontractors. “Tenant’s Hard Cost Share” shall be determined as the ratio of Xxxxxxxx’s good faith estimate of Actual Subcontracted Costs to the total cost of Landlord’s Contractors subcontracts with Landlord’s Tenant Improvement Work Subcontractors. For example, if Landlords good faith estimate of the Actual Subcontracted Cost is $750,000 and the total cost of the Landlord’s Contractor’s subcontracts with Landlord’s Tenant Improvement Work Subcontractors is $1,500,000, then Tenant will fund 50% of the portion each such requisition that relates to such subcontracts, and Landlord shall be responsible for the remainder.

c. Billing Process for Xxxxxx’s Share of the Total Cost of Landlord’s Tenant Improvement Work. Tenant shall, within thirty (30) days of invoice, pay the Total Cost of Landlord’s Tenant Improvement Work to Landlord, as such costs incurred by Landlord. Landlord may only submit invoices to Tenant on account of the Total Cost of Landlord’s Tenant Improvement Work only one time per calendar month.

d. Reconciliation of the Total Cost of Landlord’s Tenant Improvement Work. Within 60 days following the Base Building Certificate of Occupancy Date and the closing out of the subcontract(s) that include Actual Subcontract Costs, Landlord shall provide to Tenant a full accounting of the Total Cost of Landlord’s Tenant Improvement Work, together with such reasonable back-up as is required to evidence the same, and the parties shall reconcile amounts previously paid by Tenant such that Landlord is paid in full for Xxxxxxxx’s Tenant Improvement Work (i.e with Landlord reimbursing Tenant on account of any overpayment of Tenant of the Total Cost of

Landlord’s Tenant Improvement Work or Tenant paying to Landlord any underpayment of Landlord’s Tenant Improvement Work).

e. Application of Landlord’s Contribution towards Payment of the Total Cost of Landlord’s Tenant Improvement Work. Upon the completion of such reconciliation, as set forth in Section 3.2(a)(iii)(d) above: (i) Tenant shall be deemed to have submitted a requisition (“Deemed Requisition”) to Landlord for payment to Tenant from Landlord’s Contribution in accordance with Section 3.4(b) on account of the amount of Total Cost of Landlord’s Tenant Improvement Work paid for by Tenant, and (ii) Landlord shall, subject to the provisions of Section 3.4(b), make payment to Tenant on account of such Deemed Requisition.

(iv) Determination of Hard Cost of Landlord’s Tenant Improvement Work. For the purpose of determining Hard Cost of Landlord’s Tenant Improvement Works, the parties agree that the following terms shall apply:

·“Actual Subcontracted Cost” shall be defined as the actual costs of performing Landlord’s Tenant Improvement Work performed by subcontractors of Landlord’s Contractor. Since the same subcontractors who will be performing Landlord’s Tenant Improvement Work will also be performing other portions of Landlord’s Work, the Actual Subcontracted Cost shall be determined based upon the good faith allocation by Xxxxxxxx’s Contractor and relevant subcontractors of the costs payable to such subcontractors in performing Landlord’s Work. Landlord shall make available the bid tabs for subcontracts in excess of $50,000 associated with the Landlord’s Tenant Improvement Work for purposes of Tenant confirming the pricing and costs of the same.

·“General Conditions Cost” shall be defined as 9% of the Actual Subcontracted Cost

·“Insurance Cost” shall be defined as 1% of the Actual Subcontracted Cost

·“Direct Cost” shall be defined as the sum of: (i) Actual Subcontracted Cost, (ii) General Conditions Cost, plus (iii) Insurance Cost

·“Fee” shall be defined as 3% of Direct Cost

·“Building Permit Cost” shall be defined as 1.5% of the Actual Subcontracted Cost.

·“Hard Cost of Landlord’s Tenant Improvement Work” shall be defined as the sum of: (i) the Direct Cost, (ii) the Fee, plus (iii) the Building Permit Cost.

(b) Construction Documents. Landlord shall cause its architect to prepare the Construction Documents. The Construction Documents shall subject to Tenant’s prior written approval, which approval shall not be unreasonably withheld, conditioned, or delayed; provided, however, in no event shall any changes to the Construction Documents modify or be inconsistent with the requirements set forth herein or modify Landlord’s Tenant Improvement Work. Xxxxxx agrees to respond to any request for approval of the Construction Documents within five (5) business days after receipt thereof and to respond to any re-submitted request for approval of the Construction Documents following initial

submittal of the same within three (3) business days after receipt thereof. The weekly meetings described in Section 3.2(b) below shall include discussions of any changes to Landlord’s Work (other than minor changes in the nature of field work). Landlord shall promptly provide Tenant with copies of any changes in the Construction Documents. Following the approval by Landlord of Tenant’s Schematic Plans, Landlord shall reimburse Tenant for any reasonable increase in the out-of-pocket costs of the design and construction of Tenant’s Work to the extent resulting directly from any material changes in the Construction Documents (it being understood that minor changes in the nature of field work and changes that are reasonably inferable from the Construction Documents shall not be deemed material) as reasonably documented by Tenant to Landlord so long as Tenant notified Landlord of the need therefor reasonably in advance of implementing the same, giving Landlord a reasonable opportunity to attempt to eliminate the need for such changes to Tenant’s Plans. Landlord shall provide to Tenant a status report and update of the schedule for the design of Landlord’s Work until the Construction Documents have been completed and approved.

(c) Performance. Landlord’s Work shall be performed by X.X. Xxxxxxx Company (or such other general contractor selected by Landlord and reasonably approved by Tenant) under a construction contract with Landlord. Xxxxxxxx’s Work will be designed and constructed in a good and workmanlike manner, and in full compliance with all Legal Requirements. Landlord will procure in a timely fashion and thereafter maintain all necessary approvals and permits from all state and local governmental agencies having authority over the construction of Landlord’s Work. Landlord shall provide Tenant with copies of such permits (if already issued) or after the issuance thereof, as applicable. Landlord shall: (x) commence the Initial Phase of Landlord’s Work before or promptly after the Execution Date, (y) subject to delays caused by Force Majeure and/or Tenant Delay, use diligent efforts to Substantially Complete the Initial Phase of Landlord’s Work on or before the Initial Phase Target Date, and (z) subject to delays caused by Force Majeure and/or Tenant Delay, use diligent efforts to achieve the Base Building Certificate of Occupancy Date on or before March 1, 2019 (“Estimated Base Building Certificate of Occupancy Date”). Landlord shall schedule and conduct weekly meetings regarding the scheduling, progress, performance and construction of Landlord’s Work. Subject to delays caused by Force Majeure and/or Tenant Delay, Landlord shall complete each portion of the Post-Certificate of Occupancy Phase of Landlord’s Base Building Work on or before June 1, 2019 (the “Target Date for Completion of such Portion of Post-Certificate of Occupancy Phase of Landlord’s Base Building Work”). Periodically between such meetings, at Tenant’s request, Landlord shall provide Tenant with status updates regarding the progress of Landlord’s Work. During the course of design and construction, Landlord shall cause the construction schedule for Landlord’s Work to be updated periodically to reflect the actual progress of design and construction, as applicable, and shall cause such updates to be delivered to Tenant at the next weekly meeting after Xxxxxxxx’s receipt thereof, but such updates shall not result in or be deemed to constitute Tenant’s approval of any failure to timely Substantially Complete the Initial Phase of Landlord’s Work or to achieve the Base Building Certificate of Occupancy Date in the absence of a Tenant Delay or Force Majeure.

(d) Substantial Completion; Base Building Certificate of Occupancy Date; Punchlist Items.

(i) Initial Phase of Landlord’s Work. Subject to Section 3.2(d)(iii) below, “Substantially Complete,” when referring to the Initial Phase of Landlord’s Work, shall mean that the Initial Phase of Landlord’s Work is complete, except for any Initial Phase Punchlist items, as hereinafter defined, and Tenant has received a certificate from Landlord’s architect confirming the same. Tenant may, within five (5) business days following delivery of the Landlord’s architect’s certificate, dispute the occurrence of Substantial Completion by written notice to Landlord.

(ii) Balance of Landlord’s Work. Subject to Section 3.2(d)(iii) below, the “Base Building Certificate of Occupancy Date” shall mean the date when: (w) the Satisfactory Building Conditions, as defined in Section 3.1, are satisfied, (x) all of Landlord’s Work other than the Post-Certificate of Occupancy Phase of Landlord’s Base Building Work is complete, except for any Balance of Landlord’s Work Punchlist items, as hereinafter set forth, (y) all conditions for the issuance of a temporary or permanent certificate of occupancy for the Building and Premises, or such other documentation (“Other Documentation”) as will permit Tenant to lawfully occupy the Premises and conduct its business in accordance with this Lease (Collectively, “CO Conditions”) are satisfied, other than to the extent resulting from the state of Tenant’s Work, and (z) Landlord provides Tenant with a certificate of Landlord’s architect confirming the same. If the City of Framingham subsequently withdraws any Other Documentation (or otherwise prohibits Tenant from occupying the Premises for the conduct of its business notwithstanding the existing of the Other Documentation) following satisfaction of the CO Conditions based on such Other Documentation, then the CO Conditions shall not be deemed to be satisfied until the City of Framingham either issues a Certificate of Occupancy or again issues Other Documentation. Tenant may, within five (5) business days following delivery of the Landlord’s architect’s certificate, dispute the occurrence of the Base Building Certificate of Occupancy Date by written notice to Landlord.

(iii) Effect of Tenant Delays. Notwithstanding anything to the contrary herein contained: (x) in the event of any Tenant Delay affecting the Initial Phase of Landlord’s Work, the date of Substantial Completion of the Initial Phase of Substantial Completion of Landlord’s Work shall be the date that Landlord would have achieved Substantial Completion of the Initial Phase of Landlord’s Work, but for such Tenant Delay, (y) in the event of any Tenant Delay affecting the Balance of Landlord’s Work, the Base Building Certificate of Occupancy Date shall be the date that Landlord would have achieved the Base Building Certificate of Occupancy Date, but for such Tenant Delay, (z) in the event of any Tenant Delay affecting the completion of any portion of the Post-Certificate of Occupancy Phase of Landlord’s Base Building Work, the date of completion of such portion of the Post-Certificate of Occupancy Phase of Landlord’s Base Building Work shall be the date that Landlord would have achieved completion of such portion of Post-Certificate of Occupancy Phase of Landlord’s Base Building Work, but for such Tenant Delay. Nothing in this paragraph shall relieve Landlord of its obligation to complete the Landlord’s Work in accordance with this Lease.

(iv) Punchlist.

(x) Initial Phase Punchlist. Within ten (10) days following Substantial Completion of the Initial Phase of Landlord’s Work, Landlord shall provide Tenant with a Punchlist (“Initial Phase Punchlist”) prepared by Landlord’s architect incorporating those items, jointly identified by Landlord and Tenant during their joint inspection of the Initial Phase of Landlord’s Work that shall have occurred at or within five (5) days after Substantial Completion, of outstanding items which (a) need to be performed to complete the Initial Phase of Landlord’s Work, (b) do not individually or in the aggregate prevent the commencement and prosecution of Tenant’s Work (the “Initial Phase Punchlist Items”). Subject to Force Majeure and Tenant Delays, Landlord shall complete the Initial Phase Punchlist on or before the Base Building Certificate of Occupancy Date in a manner that does not disturb or interfere with the progress of Xxxxxx’s Work.

(y) Balance of Landlord’s Work Punchlist. Within ten (10) days following the Base Building Certificate of Occupancy Date, Landlord shall provide Tenant with a Punchlist (“Balance of Landlord’s Work Punchlist”) prepared by Xxxxxxxx’s architect incorporating those items, jointly identified by Landlord and Tenant during their joint inspection of Landlord’s Work that shall have occurred at or within five (5) days after Substantial Completion, of outstanding items which do not individually or in the aggregate prevent the use of the Premises for the Permitted Uses, or the exercise of

Tenant’s rights under this Lease, all in a manner consistent with Punchlist items typically found in a first-class office and laboratory facility (the “Balance of Landlord’s Work Punchlist Items”). Subject to Force Majeure and Tenant Delays, Landlord shall complete all Balance of Landlord’s Work Punchlist Items which are located within the Premises or which affect Tenant’s use of the Premises, the Building or the Property within thirty (30) days of the date of the Balance of Landlord’s Work Punchlist, provided that Tenant reasonably cooperates (without requiring Tenant to incur any costs or to alter its operations in the Premises in more than a de minimis manner except to the extent necessary for Tenant to perform its obligations under Section 11.3 below) in connection with the completion of such Balance of Landlord’s Work Punchlist Items). Prior to Base Building Certificate of Occupancy Date, Landlord shall obtain all applicable municipal sign-offs and/or approvals of Landlord’s Work which are necessary in order to obtain the Base Building Certificate of Occupancy (except to the extent that any such sign-off and/or approval is unavailable due to the status of Tenant’s Work, in which event Landlord shall obtain the same as soon as possible thereafter).

(e) Warranty. Subject to the terms of this Section 3.2(e), Landlord warrants that the materials and workmanship comprising Landlord’s Work will be free from defects or deficiencies. Any portion of Landlord’s Work not conforming to the previous sentence may be considered defective. Landlord’s warranty excludes remedy for damage caused by abuse by any of the Tenant Parties or modifications not made by Landlord or any Landlord Party or improper or insufficient maintenance to the extent that such maintenance is not the responsibility of Landlord hereunder, it being understood and agreed that normal wear and tear and normal usage are not deemed defects or deficiencies. Landlord agrees that it shall, without cost to Tenant, correct any portion of Landlord’s Work which is found to be defective promptly following the date that Tenant gives Landlord written notice (a “Defect Notice”) of such defective condition, provided that the Defect Notice is delivered to Landlord on or before the date (the “Warranty Expiration Date”) that is three hundred sixty (360) days following the substantial completion of such portion of Xxxxxxxx’s Work, time being of the essence, it being understood and agreed that there shall be separate Warranty Expiration Dates for the Initial Portion of Landlord’s Work and the Balance of Landlord’s Work. Landlord’s obligations under this Section 3.2(e) with respect to each portion of Landlord’s Work shall expire on the applicable Warranty Expiration Date and be of no further force and effect except with respect to any defects or deficiencies in Landlord’s Work disclosed in any Defect Notice delivered before the applicable Warranty Expiration Date. In addition to and notwithstanding the foregoing, Landlord hereby agrees, at no cost to Tenant, to use reasonable efforts to enforce its warranties against any contractor performing any portion of Landlord’s Work and, if Landlord reasonably concludes in good faith that the cost to bring the claim and the resulting benefits to the Building and the occupants therein do not justify pursuing the warranty claim then Tenant may, but is not required to, obtain a non-exclusive assignment of such claim from Landlord and to pursue the same at Xxxxxx’s sole cost and expense. Nothing in this Section 3.2(e) shall be deemed to limit Landlord’s obligations for maintenance and repair in accordance with Section 10.2 of the Lease.

(f) Remedies for Delay in the Term Commencement Date. Except as set forth in this Section 3.3(f), Landlord’s failure to cause the Term Commencement Date to occur on or before the Initial Phase Target Date shall not be a default by Landlord or otherwise render Landlord liable for damages. Notwithstanding anything to the contrary contained herein, if the Term Commencement Date has not occurred:

(i) Rent Credit: by the date which is one (1) month after the Initial Phase Target Date (the “Outside Date”), subject to Tenant Delays and Force Majeure (provided that Landlord shall use commercially reasonable efforts to mitigate the impacts of Force Majeure and promptly notify Tenant of the occurrence of the same), then Tenant shall be entitled to one (1) day’s abatement of Base Rent following the Base Rent Commencement Date for each of the first forty-five (45) days that the Term

Commencement Date has not occurred, and two (2) days’ Base Rent for each such day thereafter, until the Term Commencement Date occurs, and

(ii) Self Help Right: by the date which is six (6) months after the Initial Phase Target Date (the “Drop-Dead Date”), subject to Tenant Delays and Force Majeure (provided that Landlord shall use commercially reasonable efforts to mitigate the impacts of Force Majeure and promptly notify Tenant of the occurrence of the same, and provided that such extensions for Force Majeure shall not exceed fifteen (15) months in the aggregate), then Tenant shall have the right to either (A) terminate this Lease by at least thirty (30) days’ prior written notice to Landlord (provided that if substantial completion occurs within such 30 day period then Tenant’s termination notice shall be null and void), or (B) substantially complete Landlord’s Work, on Landlord’s behalf, in which event Landlord shall reimburse Tenant within thirty (30) days after receipt of a reasonably detailed invoice for all reasonable costs and expenses incurred by Tenant in connection therewith. Tenant’s self-help rights under Section 3.2(f)(ii)(B) shall be exercised by Tenant only after Tenant has provided Landlord with notice of Tenant’s intention to exercise such right (which notice shall be delivered in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE SELF-HELP” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to Section 3.2(f)(ii) and Landlord’s failure to perform the specified obligation will trigger the provisions of Section 3.2(f)(ii), and Xxxxxxxx has failed to commence action to remedy the condition complained of within ten (10) days after its receipt of such notice (or if Landlord commences to do the act required within such ten (10) day period but fails to proceed diligently thereafter). The rights set forth in Section 3.2(f)(ii)(B) are personal to Replimune Group, Inc. and its Successor(s). If Landlord fails to reimburse Tenant for Xxxxxx’s costs incurred pursuant to this Section 3.2(f)(ii) within the aforementioned thirty (30) day period, then Tenant may send Landlord a notice in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE OFF-SET” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to this Section 3.2(f)(ii) and describing Landlord’s failure to make such reimbursement and, if Xxxxxxxx fails to reimburse Tenant within ten (10) days following delivery of such notice, then Tenant may off-set such amounts, together with interest at the Default Rate from the date incurred by Xxxxxx, against the Rent due hereunder until Xxxxxx is paid in full.

(g) Remedies in the Event of Delay in Achieving the Estimated Base Building Certificate of Occupancy Date. Except as set forth in this Section 3.3(g), Landlord’s failure to achieve the Base Building Certificate of Occupancy Date on or before Estimated Base Building Certificate of Occupancy Date, as hereinafter defined, shall not be a default by Landlord or otherwise render Landlord liable for damages. Notwithstanding anything to the contrary contained herein:

(i) Rent Credit. Notwithstanding anything to the contrary contained herein, if Landlord does not achieve the Base Building Certificate of Occupancy Date on or before the Target Base Building Certificate of Occupancy Date, subject to extension as a result of Tenant Delay or Force Majeure (provided that Landlord shall use commercially reasonable efforts to mitigate the impacts of Force Majeure and promptly notify Tenant of the occurrence of the same), then, subject to Section 3.3(g)(ii), Tenant shall be entitled to a credit against Xxxxxx’s obligation to pay Base Rent under this Lease equal to $6,591.46 for each day between the Target Base Building Certificate of Occupancy Date, as it may be extended, as aforesaid, and the date that Landlord achieves the Base Building Certificate of Occupancy Date. The “Target Base Building Certificate of Occupancy Date” shall be the later of:

(1) the earlier to occur of: (x) the actual Substantial Completion of Tenant’s Work, or (y) in that the Substantial Completion Date is delayed as the result of any Landlord Delays, the date that the Substantial Completion of Tenant’s Work would have occurred in the absence of such Landlord Delay, or

(2) thirty (30) days after the Estimated Base Building Certificate of Occupancy Date, and

(ii) Tenant Self-Help Right. Notwithstanding anything to the contrary contained herein, if any portion of the Balance of Landlord’s Work is not substantially complete on or before the date which is six (6) months after the Estimated Base Building Certificate of Occupancy Date, then Tenant shall have the right to substantially complete such portion of the Balance of Landlord’s Work, on Landlord’s behalf, in which event Landlord shall reimburse Tenant within thirty (30) days after receipt of a reasonably detailed invoice for all reasonable costs and expenses incurred by Tenant in connection therewith. Tenant’s self-help rights under this Section 3.2(g)(ii) shall be exercised by Tenant only after Tenant has provided Landlord with notice of Tenant’s intention to exercise such right (which notice shall be delivered in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE SELF-HELP” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to this Section 3.2(g)(ii) and Landlord’s failure to perform the specified obligation will trigger the provisions of this Section 3.2(g)(ii), and Xxxxxxxx has failed to commence action to remedy the condition complained of within ten (10) days after its receipt of such notice (or if Landlord commences to do the act required within such ten (10) day period but fails to proceed diligently thereafter). The provisions of this Section 3.2(g)(ii) are personal to Replimune Group, Inc. and its Successor(s). If Landlord fails to reimburse Tenant for Xxxxxx’s costs incurred pursuant to this Section 3.2(g)(ii) within the aforementioned thirty (30) day period, then Tenant may send Landlord a notice in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE OFF-SET” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to this Section 3.2(g)(ii) and describing Landlord’s failure to make such reimbursement and, if Xxxxxxxx fails to reimburse Tenant within ten (10) days following delivery of such notice, then Tenant may off-set such amounts, together with interest at the Default Rate from the date incurred by Xxxxxx, against the Rent due hereunder until Xxxxxx is paid in full

3.3 Tenant’s Work

(a) Tenant’s Plans. In connection with the performance of the work necessary to prepare the Premises for Tenant’s initial occupancy and business operations, including without limitation, the installation of all furniture and fixtures (“Tenant’s Work”), (A) Tenant has submitted to Landlord, and Landlord has approved, a preliminary description of certain aspects of Tenant’s Work attached hereto as Exhibit 4E (“Tenant’s Program”), and (B) Tenant shall submit to Landlord for Landlord’s approval (i) the name of and other reasonably requested information regarding Xxxxxx’s proposed architect, licensed structural engineer, HVAC and MEP engineers and general contractor; (ii) its schematic plans for Tenant’s Work (the “Schematic Plans”), its initial set of permit plans sufficient to permit Tenant to commence Xxxxxx’s Work (“Permit Plans”), and a full set of construction drawings (“Final Tenant’s Work Construction Drawings”) for Tenant’s Work, all in accordance with the Tenant’s Work Design Schedule attached hereto as Exhibit 4F. If Tenant is delayed in the delivery of the foregoing plans by reason of a Landlord Delay, the applicable dates shall be extended by the period of time which Tenant is so delayed. The Schematic Plans, the Permit Plans and the Final Tenant’s Work Construction Drawings are collectively referred to herein as the “Plans.” Xxxxxxxx’s approval of the architect, HVAC and MEP engineers and general contractor shall not be unreasonably withheld, conditioned or delayed. Landlord acknowledges that the architect, HVAC and MEP engineers and general contractor listed on Exhibit 4D attached hereto are hereby approved. Xxxxxxxx’s approval of the Plans shall not be unreasonably withheld, conditioned or delayed. Xxxxxxxx’s approval is solely given for the benefit of Landlord and Tenant under this Section 3.3(a) and neither Tenant nor any third party shall have the right to rely upon Landlord’s approval of the Plans for any other purpose whatsoever. Xxxxxxxx agrees to respond to any request for approval of the Plans within five (5) business days after receipt thereof and to respond to any re-submitted request for approval of the Plans following initial submittal of the same within three (3)

business days after receipt thereof. Landlord shall cooperate with Tenant, at Tenant’s sole cost and expense, in connection with Tenant’s application for any state or municipal permits or approvals required in connection with the design, construction or maintenance of Tenant’s Work, including signing applications therefor to the extent required of building or property owners; provided, however, in no event shall Tenant apply for any special permits or variances from the City of Framingham without Landlord’s approval, not to be unreasonably withheld, conditioned or delayed, it being understood and agreed that in no event shall any special permit or variance for which Tenant applies impose any conditions on Landlord unless approved by Landlord in its sole discretion.

(b) Landlord Delay. A “Landlord Delay” shall be defined as any act or omission (where Landlord has a duty to act) by Landlord or any agent, employee, consultant, contractor or subcontractor of Landlord which causes an actual delay in the design or completion of Tenant’s Work, provided that no Landlord Delay shall be deemed to occur until Tenant gives Landlord written notice of the event giving rise to such claimed Landlord Delay and a reasonable description of the same.

(c) Weekly Meetings. During the course of design and construction of Tenant’s Work, Tenant shall schedule and conduct weekly meetings regarding the scheduling, progress, performance and construction of Tenant’s Work. Tenant shall cause its approved architect, engineers and contractor to participate in such meetings as reasonably necessary and/or as reasonably requested by Landlord. Landlord and Landlord’s agents, contractors, representatives, and lenders may attend such meetings and Tenant shall provide reasonably requested information thereto at such meetings. Draft requisitions (as defined in Section 3.4 below) shall be reviewed and discussed at such meetings before being submitted to Landlord. Tenant shall periodically between such meetings, at Landlord’s request, provide Landlord with status updates regarding the progress of Tenant’s Work. During the course of design and construction, Tenant shall cause the construction schedule for Tenant’s Work to be updated periodically to reflect the actual progress of design and construction, as applicable, and shall cause such updates to be delivered to Landlord at the next weekly meeting after Xxxxxx’s receipt thereof, but such updates shall not result in or be deemed to constitute Landlord’s approval of any failure to timely Substantially Complete Tenant’s Work in the absence of a Landlord Delay or Force Majeure.

(d) Completion of Tenant’s Work. Tenant shall Substantially Complete (hereinafter defined) Tenant’s Work on or before the date that is eighteen (18) months after the Term Commencement Date (the “Outside Tenant Work Completion Date”), provided that if Tenant is delayed in the performance of Tenant’s Work by reason of a Landlord Delay or Force Majeure, the Outside Tenant Work Completion Date shall be extended by the period of time which Tenant is so delayed. For purposes hereof, Tenant’s Work shall be deemed “Substantially Complete” and “Substantial Completion” shall be deemed to have occurred if Tenant has obtained a temporary (subject only to conditions that do not prohibit Tenant from utilizing the Premises for the conduct of its business), permanent certificate of occupancy, or Other Documentation from the City of Framingham, Massachusetts, which shall be deemed to occur earlier than actual issuance of the same for purposes of the first sentence of this paragraph to the extent that a certificate of occupancy is not available as a result of Landlord’s Work or any other work being performed outside the Premises in the Building.

(e) Cost of Tenant’s Work; Priority of Work. Except for Landlord’s Contribution (hereinafter defined), all of Tenant’s Work shall be performed at Tenant’s sole cost and expense, and shall be performed in accordance with the provisions of this Lease (including, without limitation, Section 11). Landlord and Xxxxxx acknowledge and agree that Punchlist Items relating to Landlord’s Work and Tenant’s Work may be performed concurrently. The parties shall cooperate in all commercially reasonable ways to avoid any delay in either Landlord’s Work or Tenant’s Work or any conflict with the performance of either Xxxxxxxx’s Work or Tenant’s Work.

(f) Construction of Mezzanine Level. The parties acknowledge that: (i) Landlord’s Tenant Improvement Work includes the installation of structural framing to enable Tenant to in-fill a portion of the mechanical mezzanine area located in the Premises, and (ii) Tenant’s Work or future Alterations may include the in-fill such portion of the mechanical mezzanine area. If Tenant infills such a portion of the mechanic mezzanine, Tenant acknowledges and agrees that (i) in no event shall Tenant use such space for any purpose that increases the Gross Floor Area (as defined in the City of Framingham zoning bylaw at the time of the issuance of the building permit for such work) of the Building (the parties acknowledging that use of the mechanical mezzanine area for Mechanical Uses, as hereinafter defined, complies with the requirements of this clause (i)), and (ii) such space shall be devoted exclusively to the operation and maintenance of equipment and machinery serving the Premises, such as heating, ventilating and cooling equipment, electrical and telephone facilities, fuel storage, elevator machinery or mechanical equipment (collectively, for the purposes of this Section 3.3(f), “Mechanical Uses”. In no event shall any such mezzanine level be counted towards the measurement of the rentable square footage of the Premises hereunder.

(g) Loading Bays. Landlord acknowledges that Tenant shall have the exclusive right to four (4) loading bays, subject to compliance with the terms of this Section 3 and/or 11, as applicable.

(h) Connection Work. Landlord and Tenant acknowledge and agree that, as part of Tenant’s Work, Tenant may elect to perform the following work (“Connection Work”): (x) connect additional Tenant exclusive sewer and wastewater discharge pipes from the existing drain located within the loading area within the Premises to Landlord’s existing out-flow connection to municipal sewer (“Discharge Connections”), and (b) install conduit in subsurface locations outside of the Building to connect the Premises to Tenant’s nitrogen tank and emergency generator (“Tank and Generator Connections”). The Connection Work shall be performed in accordance with the provisions of this Section 3 and the other provisions of this Lease (including, without limitation, Tenant’s obligations to obtain all necessary governmental permits and approvals in order to perform any Connection Work, and Xxxxxx’s obtaining Landlord’s prior written approval of Xxxxxx’s plans and specifications for the performance of the Connection Work, which approval shall not be unreasonably withheld, conditioned, or delayed. In no event shall Tenant be permitted to submit any building permit application for any Connection Work until such time as Landlord has obtained its building permit for the Landlord’s Work. If Tenant or its contractors encounters any Hazardous Materials when making such connections, (i) Tenant shall notify Landlord immediately thereof and cease, or cause to be ceased, such work pending further direction from Landlord and (b) promptly after receipt of such notice from Tenant Landlord shall undertake the remediation of such conditions as further provided in Section 17.8 below, at its sole cost and expense such that Tenant can complete its installation without the necessity of taking any special precautions (including the remediation of soils or shipping soils off site) for Hazardous Materials. With respect to the Discharge Connections only (the parties expressly agreeing that this sentence does not apply to the Tenant and Generator Connections), so long as Tenant is working within the area approved by Landlord in connection with its approval of such work, Landlord acknowledges that any delay in the progress of the Discharge Connections resulting from remediation pursuant to the immediately preceding sentence may be a Landlord Delay. During the Term, Tenant may operate and shall repair and maintain such pipes and connections in accordance with the standards set forth in Section 10.1 below.

3.4 Landlord’s Contribution.

(a) Amount. As an inducement to Tenant’s entering into this Lease, Landlord shall, subject to Section 3.4(c) below and the last sentence of this Section 3.4(a), provide to Tenant a special tenant improvement allowance in an amount equal to $150.00 per rentable square foot of the Premises (“Landlord’s Contribution”) to be used by Tenant solely for (A) the Total Cost of Landlord’s Tenant Improvement Work and (B) hard and soft costs (including without limitation space planning and design,

signage, equipment, and telephone & data cabling) incurred by Tenant for Tenant’s Work, provided, however, in no event shall more than ten percent (10%) of Landlord’s Contribution be used for such soft costs. For the purposes hereof, the cost to be so reimbursed by Landlord shall not include: (i) except as set forth above, the cost of any of Tenant’s Property (hereinafter defined), and (ii) any fees paid to Tenant or any affiliate of Tenant.

(b) Requisitions. Subject to Section 3.4(c) below, Landlord shall pay Landlord’s Proportion (hereinafter defined) of the cost shown on each requisition (hereinafter defined) submitted by Tenant to Landlord within thirty (30) days of submission thereof by Tenant to Landlord until the entirety of Landlord’s Contribution has been exhausted. “Landlord’s Proportion” shall be a fraction, the numerator of which is Landlord’s Contribution and the denominator of which is the sum of: (i) total price for all of Tenant’s Work for the Premises (as evidenced by reasonably detailed documentation, including without limitation copies of all contracts therefor, delivered to Landlord with the requisition first submitted by Tenant), plus (ii) Total Cost of Landlord’s Tenant Improvement Work, but in no event greater than one (1). A “requisition” shall mean written documentation (including, without limitation, invoices or bills from Tenant’s contractors, vendors, service providers and consultants (collectively, “Contractors”) and partial lien waivers and subordinations of lien in statutory form, as specified in M.G.L. Chapter 254, Section 32 for applicable contractors and service providers (“Lien Waivers”) with respect to the prior month’s requisition, and such other documentation as Landlord or any Mortgagee may reasonably request) showing in reasonable detail the costs of the item in question or of the improvements installed to date in the Premises, accompanied by reasonable evidence (including certifications executed by Tenant or Xxxxxx’s architect, subject to the architect’s standard of care) that the amount of the requisition in question does not exceed the cost of the items, services and work covered by such requisition. Notwithstanding the foregoing or anything herein to the contrary, Tenant shall not be required to deliver Lien Waivers (i) at the time of the first requisition, but shall deliver the Lien Waivers and evidence of payment of the first requisition in full within five (5) days following payment of Landlord’s Contribution with respect to such first requisition, or (ii) from any subcontractors or suppliers providing services or materials [STILL WAITING FOR CONFIRMATION FROM LANDLORD’S MORTGAGEE: costing less than $25,000 in the aggregate]. Landlord shall have the right, upon reasonable advance notice to Tenant, to inspect Tenant’s books and records relating to each requisition in order to verify the amount thereof. Tenant shall submit requisition(s) no more often than monthly. Furthermore, Tenant shall have no obligation to submit a requisition or related materials with respect to Landlord’s Tenant Improvement Work, such amounts being due and payable to Tenant upon Tenant’s request in accordance with Section 3.2(a).

(c) Notwithstanding anything to the contrary herein contained: (i) Landlord shall have no obligation to advance funds on account of Landlord’s Contribution more than once per month (other than with respect to Landlord’s Tenant Improvement Work).; (ii) if Tenant fails to pay to Tenant’s contractors the amounts paid by Landlord to Tenant in connection with any previous requisition(s), Landlord shall thereafter have the right to have Landlord’s Contribution paid directly to Tenant’s contractors; (iii) Landlord shall have no obligation to pay any portion of Landlord’s Contribution with respect to any requisition submitted after the date (the “Outside Requisition Date”) which is, subject to extension to the extent that the completion of the Tenant’s Work is delayed due to Force Majeure and Landlord Delay, the earlier of: (a) six (6) months after the completion of Tenant’s Work, or (b) twenty-four (24) months after the Term Commencement Date; provided, however, that if Tenant certifies to Landlord that it is engaged in a good faith dispute with any contractor, such Outside Requisition Date shall be extended while such dispute is ongoing, so long as Tenant is diligently prosecuting the resolution of such dispute; (iv) Tenant shall not be entitled to any unused portion of Landlord’s Contribution; (v) Xxxxxxxx’s obligation to pay any portion of Landlord’s Contribution shall be conditioned upon there existing no default by Tenant in its obligations under this Lease at the time that Landlord would otherwise be required to make such payment (it being understood and agreed that if Tenant cures any such defaults

prior to the expiration of applicable notice and cure periods, Landlord shall thereafter make such payment); and (vi) in addition to all other requirements hereof, Landlord’s obligation to pay the final five percent (5%) of Landlord’s Contribution shall be subject to simultaneous delivery of all Lien Waivers relating to items, services and work performed in connection with Xxxxxx’s Work.

(d) If Landlord fails to timely pay any installment of Landlord’s Contribution pursuant to this Section 3.4, then Tenant may send Landlord a notice in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE OFF-SET” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to this Section 3.4(d) and describing Landlord’s failure to make such payment and, if Landlord fails to make such payment to Tenant within ten (10) days following delivery of such notice, then Tenant may off-set against the Rent due hereunder an amount equal to such installment(s) of Landlord’s Contribution which Xxxxxxxx fails to timely pay, together with interest at the Default Rate from the date on which such installment was due, until (i) Tenant is paid in full for such installment, or (ii) Landlord pays the balance of such installment to Tenant.

From and after the Execution Date, Landlord shall include substantially similar provisions in any other leases at the Building and shall not enforce such provisions in a discriminatory manner.

(b) With respect to the use and occupancy of the Premises and the Common Areas, Tenant will not: (i) place or maintain any signage (except as set forth in Section 12.2 below), trash, refuse or other articles in any vestibule or entry of the Premises, on the footwalks or corridors adjacent thereto or elsewhere on the exterior of the Premises, nor obstruct any driveway, corridor, footwalk, parking area, mall or any other Common Areas; (ii) permit undue accumulations of or burn garbage, trash, rubbish or other refuse within or without the Premises; (iii) permit the parking of vehicles

Rent shall be payable to Landlord or, if Landlord shall so direct in writing, to Landlord’s agent or nominee, in lawful money of the United States which shall be legal tender for payment of all debts and dues, public and private, at the time of payment.

5.2 Operating Costs.

(a) “Operating Costs” shall mean all reasonable costs incurred and expenditures of whatever nature made by Landlord in the operation, management, repair, replacement, maintenance and insurance of the Property or allocated to the Property, including without limitation any costs for utilities supplied to exterior areas of the Property and the Common Areas, and any costs for repair and replacements, cleaning and maintenance of exterior areas and the Common Areas, related equipment, facilities and appurtenances and HVAC equipment, a commercially reasonable management fee paid to Landlord’s property manager not to exceed 4% of gross rents from the Building, and the cost of operating and maintaining the Outside Seating Area, as defined in Section 1.3(e) of this Lease.

the Landlord’s Work pursuant to Section 3.2 above) and any contributions made by Landlord to any tenant of the Property in connection with the build-out of its premises; (vii) franchise or income taxes imposed on Landlord; (viii) costs paid directly by individual tenants to suppliers, including tenant electricity, telephone and other utility costs; (ix) increases in premiums for insurance when such increase is caused by the use of the Building by Landlord or any other tenant of the Building; (x) maintenance and repair of capital items not a part of the Building or the Property; (xi) depreciation of the Building; (xii) costs relating to maintaining Landlord’s existence as a corporation, partnership or other entity; (xiii) advertising and other fees and costs incurred in procuring tenants; (xiv) the cost of any items for which Landlord is reimbursed by insurance, condemnation awards, refund, rebate or otherwise, and any expenses for repairs or maintenance to the extent covered by warranties, guaranties and service contracts; (xv) costs incurred in connection with any disputes between Landlord and its employees, between Landlord and Building management, or between Landlord and other tenants or occupants; (xvi) accounting fees; (xvii) fines and penalties; (xviii) costs and expenses of investigating, monitoring or remediating existing hazardous materials on, under or about the Building or the Property; (xix) costs of selling, syndicating, financing or refinancing any portion of the Property and/or of Landlord’s interest therein (including interest, principal, points and fees, interest on debt or amortization payments on any mortgage or deed to secure debt and rental under any ground lease, master lease or other underlying lease, and other debt costs, if any); (xx) charitable or political contributions; (xxi) all items and services for which Tenant is separately charged, reimburses Landlord or pays third persons; (xxii) reserves of any kind (including without limitation reserves for bad debts or rent loss) or any bad debt loss or rent loss; (xxiii) the costs of goods and services provided by affiliates of Landlord, to the extent only that the costs of such goods and/or services exceed the market rate for goods or services of comparable quality provided by unrelated third parties; (xxiv) costs incurred to develop and construct additional structures on the Property (including without limitation any Future Development), (xxv) costs appropriately allocable to any other building (any Operating Costs that are incurred with respect to the Building and any other building located on the Property or another property shall be allocated between such buildings based on the rentable square footage of such buildings unless another method more equitably reflects the benefit of such costs), (xxvi) the cost of acquiring (as opposed to leasing) sculptures, paintings and other objects of art (provided, however, that any costs of leasing sculptures, paintings and other objects of art shall be customary for first-class buildings in the vicinity of the Property); (xxvii) the cost of advertising or promotion of (A) the Property or any part thereof or (B) any operations at the Property; (xxviii) Landlord’s general overhead.

(c) Payment of Operating Costs. Tenant shall pay to Landlord, as Additional Rent, Xxxxxx’s Share of Operating Costs. Landlord shall make a good faith estimate of Xxxxxx’s Share of Operating Costs for any fiscal year or part thereof during the Term and notify Tenant of such estimate no later than thirty (30) days prior to each fiscal year, and Tenant shall pay to Landlord, on the Additional Rent Commencement Date and on the first (1st) day of each calendar month thereafter, an amount equal to Xxxxxx’s Share of Operating Costs for such fiscal year and/or part thereof divided by the number of months therein. Upon at least thirty (30) days’ notice, Landlord may estimate and re-estimate Xxxxxx’s Share of Operating Costs and deliver a copy of the estimate or re-estimate to Tenant, provided that no more than one re-estimate may be made in any given fiscal year. Thereafter, the monthly installments of Tenant’s Share of Operating Costs shall be appropriately adjusted in accordance with the estimations so that, by the end of the fiscal year in question, Tenant shall have paid all of Tenant’s Share of Operating Costs as estimated by Xxxxxxxx. Any amounts paid based on such an estimate shall be subject to reconciliation as herein provided when actual Operating Costs are available for each fiscal year.

(d) Annual Reconciliation. Landlord shall, within one hundred twenty (120) days after the end of each fiscal year, deliver to Tenant a reasonably detailed statement of the actual amount of Operating Costs for such fiscal year (“Year End Statement”). Failure of Landlord to provide the Year End Statement within the time prescribed shall not relieve Tenant from its obligations hereunder, provided, however, Landlord shall be deemed to have waived any costs actually incurred but not billed to Tenant within two (2) years after the end of the fiscal year in which such cost was incurred by Landlord.

If the total of such monthly remittances on account of any fiscal year is greater than Tenant’s Share of Operating Costs actually incurred for such fiscal year, then, provided no Event of Default nor any event which, with the passage of time and/or the giving of notice would constitute an Event of Default, is then continuing (it being understood and agreed that if Tenant cures any default(s) within the applicable cure period(s) provided in Section 20 below, then Tenant shall thereafter be entitled to take such credit), Tenant may credit the difference against the next installment(s) of Additional Rent on account of Operating Costs due hereunder, except that if such difference is determined after the end of the Term, Landlord shall refund such difference to Tenant within thirty (30) days after such determination to the extent that such difference exceeds any amounts then due from Tenant to Landlord. If the total of such remittances is less than Xxxxxx’s Share of Operating Costs actually incurred for such fiscal year, Tenant shall pay the difference to Landlord, as Additional Rent hereunder, within thirty (30) days of Tenant’s receipt of an invoice therefor. Xxxxxxxx’s estimate of Operating Costs for the next fiscal year shall be based upon the Operating Costs actually incurred for the prior fiscal year as reflected in the Year-End Statement plus a reasonable adjustment based upon estimated increases in Operating Costs, if any. The provisions of this Section 5.2(d) shall survive the expiration or earlier termination of this Lease.

(e) Partial Years. If the Additional Rent Commencement Date or the Expiration Date occurs in the middle of a fiscal year, Tenant shall be liable for only that portion of the Operating Costs with respect to such fiscal year within the Term from and after the Additional Rent Commencement Date.

(f) Gross-Up. If, during any fiscal year, less than 95% of the Building is occupied by tenants or if Landlord was not supplying all tenants with the services being supplied to Tenant hereunder, actual Operating Costs incurred shall be reasonably extrapolated by Landlord on an item-by-item basis to the reasonable Operating Costs that would have been incurred if the Building was 95% occupied and such services were being supplied to all tenants, and such extrapolated Operating Costs shall, for all purposes hereof, be deemed to be the Operating Costs for such fiscal year. This “gross up” treatment shall be applied only with respect to variable Operating Costs arising from services provided to Common Areas or to space in the Building being occupied by tenants (which services are not provided to vacant space, i.e. such Operating Costs vary with occupancy, or may be provided only to some tenants) in order to allocate equitably such variable Operating Costs to the tenants receiving the benefits thereof.

(g) Audit. Provided there is no Event of Default nor any event which, with the passage of time and/or the giving of notice would constitute an Event of Default, Tenant may, upon at least ten (10) days’ prior written notice, inspect or audit Landlord’s records relating to Operating Costs and/or Taxes for any periods of time within the previous fiscal year before the audit or inspection (it being understood that if Tenant shall cure any such default within applicable notice and/or cure periods provided in Section 20.1 below, then Tenant shall thereafter be entitled to perform such inspection or audit). Landlord shall provide Tenant with access to such records at a location within the Greater Boston area in accordance with this Section 5.2(g) within ten (10) days after receipt of notice from Tenant. However, no audit or inspection shall extend to periods of time before the Additional Rent Commencement Date. If Tenant fails to object to the calculation of Xxxxxx’s Share of Operating Costs and/or Taxes on the Year-End Statement within ninety (90) days after such statement has been delivered to Tenant and/or fails to complete any such audit or inspection within sixty (60) days after Landlord’s records are made available to Tenant in accordance with this Section 5.2(g), then Tenant shall be deemed to have waived its right to object to the calculation of Tenant’s Share of Operating Costs and/or Taxes, as the case may be, for the year in question and the calculation thereof as set forth on such statement shall be final. Tenant’s audit or inspection shall be conducted only at Landlord’s offices or the offices of Landlord’s property manager at a location within the Greater Boston area during business hours reasonably designated by Landlord. Tenant shall pay the cost of such audit or inspection, provided, however, that if such audit discloses that Tenant has been overcharged by more than five percent (5%), Landlord shall reimburse Tenant for Tenant’s reasonable out-of-pocket costs incurred in connection with such audit. Tenant may not conduct an inspection or have an audit performed more than once during any

fiscal year. If such inspection or audit reveals that an error was made in the calculation of Tenant’s Share of Operating Costs or Taxes previously charged to Tenant, then, provided there is no Event of Default nor an event which, with the passage of time and/or the giving of notice would constitute an Event of Default, Tenant may credit the difference against the next installment of Additional Rent on account of Operating Costs or Taxes, as the case may be, due hereunder (it being understood that if Tenant shall cure any such default within applicable notice and/or cure periods provided in Section 20.1 below, then Tenant shall thereafter be entitled to take such credit), except that if such difference is determined after the end of the Term, Landlord shall refund such difference to Tenant within thirty (30) days after such determination to the extent that such difference exceeds any amounts then due from Tenant to Landlord. If such inspection or audit reveals an underpayment by Xxxxxx, then Tenant shall pay to Landlord, as Additional Rent hereunder, any underpayment of any such costs, after deducting the reasonable out of pocket costs of such inspection or audit, within thirty (30) days after such underpayment is determined. Tenant shall maintain the results of any such audit or inspection confidential and shall not be permitted to use any third party to perform such audit or inspection, other than an independent firm of certified public accountants (A) reasonably acceptable to Landlord, (B) which is not compensated on a contingency fee basis or in any other manner which is dependent upon the results of such audit or inspection, and (C) which executes Landlord’s standard confidentiality agreement whereby it shall agree to maintain the results of such audit or inspection confidential. The provisions of this Section 5.2(g) shall survive the expiration or earlier termination of this Lease.

5.3 Taxes.

(a) “Taxes” shall mean the real estate taxes and other taxes, levies and assessments imposed upon the Building and the Land, and upon any personal property of Landlord used in the operation thereof, or on Landlord’s interest therein or such personal property; charges, fees and assessments for transit, housing, police, fire or other services or purported benefits to the Building and the Land (including without limitation any community preservation assessments) that are charged on the real estate tax bills issued by the City of Framingham to all property owners in the City; service or user payments in lieu of taxes; and any and all other taxes, levies, betterments, assessments and charges arising from the ownership, leasing, operation, use or occupancy of the Building and the Land or based upon rentals derived therefrom, which are or shall be imposed by federal, state, county, municipal or other governmental authorities. From and after substantial completion of any occupiable improvements constructed as part of a Future Development, if such improvements are not separately assessed, Landlord shall reasonably allocate Taxes between the Building and such improvements and the land area associated with the same and shall, as soon as possible thereafter, seek to have such building separately assessed. From and after the issuance of a building permit for construction of any occupiable improvements constructed as part of a Future Development, Taxes shall not include any Taxes assessed on such improvements under construction to the extent evidenced by the City of Framingham’s assessors’ records. Taxes shall not include (i) any inheritance, estate, succession, gift, franchise, rental, income or profit tax, capital stock tax, capital levy or excise, or any income taxes arising out of or related to the ownership and operation of the Building and the Land, provided, however, that any of the same and any other tax, excise, fee, levy, charge or assessment, however described, that may in the future be levied or assessed as a substitute for or an addition to, in whole or in part, any tax, levy or assessment which would otherwise constitute Taxes, whether or not now customary or in the contemplation of the parties on the Execution Date of this Lease, shall constitute Taxes, but only to the extent calculated as if the Building and the Land were the only real estate owned by Xxxxxxxx, (ii) any interest or penalties resulting from the late payment of Taxes by Landlord (except to the extent due to Tenant’s failure to make timely payments), (iii) any taxes assessed against air or other development rights; (iv) any environmental assessments, charges or liens arising in connection with the remediation of Hazardous Materials from the Building or Property (provided that the foregoing shall not be deemed to derogate from Tenant’s obligations set forth in Section 17 below with respect to Hazardous Materials); (v) costs or fees payable to public authorities in connection with the Landlord’s Work (other than real estate taxes resulting from the construction of the Landlord’s Work) and any future construction of additional buildings or similar improvements on the

Property (including any such fees for transit, housing, schools, open space, child care, arts programs, traffic mitigation measures, environmental impact reports and traffic studies); (vi) reserves for future Taxes; and any personal property taxes attributable to sculptures, paintings or other objects of art. “Taxes” shall also include reasonable expenses (including without limitation legal and consultant fees) of tax abatement or other proceedings contesting assessments or levies.

(b) “Tax Period” shall be any fiscal/tax period in respect of which Taxes are due and payable to the appropriate governmental taxing authority (i.e., as mandated by the governmental taxing authority), any portion of which period occurs during the Term of this Lease.

(c) Payment of Taxes. Tenant shall pay to Landlord, as Additional Rent, Xxxxxx’s Building Share of Taxes relating to or allocable to the Building and Tenant’s Share of Taxes relating to or allocable to the Land. At least thirty (30) days prior to the Additional Rent Commencement Date, Landlord shall notify Tenant of Landlord’s good faith estimate of the Taxes to be due by Tenant for the Tax Period in which the Additional Rent Commencement Date occurs, and Tenant shall pay to Landlord, on the Additional Rent Commencement Date and on the first (1st) day of each calendar month thereafter, an amount equal to Landlord’s estimate of Tenant’s Share of Taxes for such Tax Period or part thereof divided by the number of months therein. Upon at least thirty (30) days’ notice, Landlord may estimate and re-estimate Xxxxxx’s Share of Taxes and deliver a copy of the estimate or re-estimate to Tenant, provided that Landlord shall not re-estimate Tenant’s Share of Taxes more than one time in any fiscal year. Thereafter, the monthly installments of Tenant’s Share of Taxes shall be appropriately adjusted in accordance with the estimations so that, by the end of the Tax Period in question, Tenant shall have paid all of Tenant’s Share of Taxes as estimated by Xxxxxxxx. Any amounts paid based on such an estimate shall be subject to adjustment as herein provided when actual Taxes are available for each Tax Period. If the total of such monthly remittances is greater than Tenant’s Share of Taxes actually due for such Tax Period, then, provided no Event of Default nor any event which, with the passage of time and/or the giving of notice would constitute an Event of Default is then continuing (it being understood and agreed that if Tenant cures any default(s) within the applicable cure period(s) provided in Section 20 below, then Tenant shall thereafter be entitled to take such credit), Tenant may credit the difference against the next installment(s) of Additional Rent on account of Taxes due hereunder, except that if such difference is determined after the end of the Term, Landlord shall refund such difference to Tenant within thirty (30) days after such determination to the extent that such difference exceeds any amounts then due from Tenant to Landlord. If the total of such remittances is less than Tenant’s Share of Taxes actually due for such Tax Period, Tenant shall pay the difference to Landlord, as Additional Rent hereunder, within thirty (30) days of Tenant’s receipt of an invoice therefor. Xxxxxxxx’s estimate for the next Tax Period shall be based upon actual Taxes for the prior Tax Period plus a reasonable adjustment based upon estimated increases in Taxes. The provisions of this Section 5.3(c) shall survive the expiration or earlier termination of this Lease.

(d) Abatements.

(i) Landlord may at any time contest any valuation of the Land, the Building or the Premises, or any tax rate, or the amount of any Taxes, by legal proceedings or in such other manner as it may deem suitable. If Tenant desires to institute such a contest, Tenant shall notify Landlord of such desire on or before the date which is thirty (30) days before the deadline to contest the same. Unless Landlord notifies Tenant at least ten (10) business days before such deadline that Landlord will institute such a contest, then, provided that during such real estate tax year Tenant’s Share is at least fifty percent (50%), Tenant shall have the right during or after the Term of this Lease to contest or review any valuation of the Building or the Premises, or any tax rate, of the amount of any Taxes for such real estate tax year, by legal proceedings or in such other manner as it may deem suitable. If Tenant elects to institute such a proceeding, Tenant shall conduct it in the name of Tenant, provided that if any such proceeding which Tenant elects to institute must be prosecuted in the name of Landlord, Landlord shall permit Tenant to institute and prosecute it in the name of Landlord as provided above, but Landlord shall

not settle any proceeding so instituted by Tenant without Xxxxxx’s prior written approval in each instance. If any such proceeding is instituted in the name of Tenant, Tenant shall not settle such proceeding without Landlord’s prior written approval in each instance, which approval shall not be unreasonably withheld. If Tenant institutes such a proceeding, Tenant (A) shall prosecute it diligently and in good faith at all times, (B) shall prosecute it at its sole cost and expense (subject to reimbursement as provided below in this Section 5.3(d), (C) shall periodically advise Landlord as to the status thereof, and (D) shall not abandon the same without first offering to Landlord the right to prosecute the same (and in the event that Landlord elects to continue such proceeding, Tenant shall promptly assign and turn over to Landlord the control of such proceeding, and thereafter Tenant shall have no further liability or responsibility in connection therewith). Landlord (at no cost to Landlord) shall cooperate with Tenant to the extent reasonably necessary to enable Tenant to institute and prosecute such proceeding including, without limitation, providing all information and documents reasonably requested by Xxxxxx, executing all documents necessary to accomplish the foregoing, and making such appearances as Tenant may reasonably request.

(ii) If Landlord or Tenant obtains a refund or abatement of Taxes, (A) the parties shall first be entitled to receive reimbursement from any refund or abatement for all expenses, including reasonable attorney’s fees, incurred by it in connection with obtaining such refund or abatement, and (B) then, if Tenant has paid Taxes or estimated Taxes for the period for which the refund has paid Taxes or estimated Taxes for the period for which the refund or abatement was granted, Tenant shall be entitled to receive Tenant’s Share of the abatement (with interest, if any, paid by the Governmental Authority on such abatement), adjusted for any period for which Xxxxxx had made a partial payment.

(iii) Appropriate credit against Taxes (or payments to Tenant following the termination this Lease) shall be given for any refund obtained by reason of a reduction in any Taxes by the assessors or the administrative, judicial or other governmental agency responsible therefor after deduction of Landlord’s expenditures for reasonable legal fees and for other reasonable expenses incurred in obtaining the Tax refund. If Tenant provides Landlord with reasonable evidence that any exemption from real property taxes for the Property is due to any Tax Increment Financing Agreement (“TIFA”) entered into by Tenant and the City of Framingham, then the benefit of such exemption shall be allocated entirely to Tenant.

(e) Part Years. If the Additional Rent Commencement Date or the Expiration Date occurs in the middle of a Tax Period, Tenant shall be liable for only that portion of the Taxes, as the case may be, with respect to such Tax Period within the Term from and after the Additional Rent Commencement Date.

5.4 Late Payments.

(a) Any payment of Rent due hereunder not paid when due shall bear interest for each month or fraction thereof from the due date until paid in full at the annual rate of twelve percent (12%), or at any applicable lesser maximum legally permissible rate for debts of this nature (the “Default Rate”). Notwithstanding the foregoing, Landlord shall not charge such interest with respect to the first late payment in any twelve (12) month period so long as received by Landlord within five (5) business days after the due date therefor.

(b) Additionally, if Tenant fails to make any payment within five (5) days after the due date therefor, Landlord may charge Tenant a fee, which shall constitute liquidated damages, equal to One Thousand and NO/100 Dollars ($1,000.00) for each such late payment. Notwithstanding the foregoing, Landlord shall not charge such fee with respect to the first late payment in any twelve (12) month period so long as received by Landlord within five (5) business days after the due date therefor.

reason, Xxxxxx shall pay a returned check charge equal to the amount as shall be customarily charged by Xxxxxxxx’s bank at the time.

(d) Money paid by Tenant to Landlord shall be applied to Xxxxxx’s account in the following order: first, to any unpaid Additional Rent, including without limitation late charges, returned check charges, legal fees and/or court costs chargeable to Tenant hereunder; and then to unpaid Base Rent.

(e) The parties agree that the late charge referenced in Section 5.4(b) represents a fair and reasonable estimate of the costs that Landlord will incur by reason of any late payment by Xxxxxx, and the payment of late charges and interest are distinct and separate in that the payment of interest is to compensate Landlord for the use of Landlord’s money by Xxxxxx, while the payment of late charges is to compensate Landlord for Landlord’s processing, administrative and other costs incurred by Landlord as a result of Tenant’s delinquent payments. Acceptance of a late charge or interest shall not constitute a waiver of Tenant’s default with respect to the overdue amount or prevent Landlord from exercising any of the other rights and remedies available to Landlord under this Lease or at law or in equity now or hereafter in effect.

(f) If Tenant is not then a publicly traded entity on a nationally recognized stock exchange and during any six (6) month period shall be more than five (5) days delinquent in the payment of any regular monthly installment of Base Rent, Operating Costs or Taxes on three (3) or more occasions, then, notwithstanding anything herein to the contrary, Landlord may, by written notice to Tenant, elect to require Tenant to pay all Base Rent and Additional Rent on account of Operating Costs and Taxes quarterly in advance. Such right shall be in addition to and not in lieu of any other right or remedy available to Landlord hereunder or at law on account of Xxxxxx’s default hereunder.

5.5 No Offset; Independent Covenants; Waiver. Rent shall be paid without notice or demand, and, except as expressly set forth herein, without setoff, counterclaim, defense, abatement, suspension, deferment, reduction or deduction. TENANT HEREBY ACKNOWLEDGES AND AGREES THAT THE OBLIGATIONS OF TENANT HEREUNDER SHALL BE SEPARATE AND INDEPENDENT COVENANTS AND AGREEMENTS, THAT RENT SHALL CONTINUE TO BE PAYABLE IN ALL EVENTS AND THAT THE OBLIGATIONS OF TENANT HEREUNDER SHALL CONTINUE UNAFFECTED, UNLESS THE REQUIREMENT TO PAY OR PERFORM THE SAME SHALL HAVE BEEN ABATED OR TERMINATED PURSUANT TO AN EXPRESS PROVISION OF THIS LEASE. LANDLORD AND TENANT EACH ACKNOWLEDGES AND AGREES THAT THE INDEPENDENT NATURE OF THE OBLIGATIONS OF TENANT HEREUNDER REPRESENTS FAIR, REASONABLE, AND ACCEPTED COMMERCIAL PRACTICE WITH RESPECT TO THE TYPE OF PROPERTY SUBJECT TO THIS LEASE, AND THAT THIS AGREEMENT IS THE PRODUCT OF FREE AND INFORMED NEGOTIATION DURING WHICH BOTH LANDLORD AND TENANT WERE REPRESENTED BY COUNSEL SKILLED IN NEGOTIATING AND DRAFTING COMMERCIAL LEASES IN MASSACHUSETTS, AND THAT THE ACKNOWLEDGEMENTS AND AGREEMENTS CONTAINED HEREIN ARE MADE WITH FULL KNOWLEDGE OF THE HOLDING IN WESSON X. XXXXX ENTERPRISES, INC., 437 MASS. 708 (2002). SUCH ACKNOWLEDGEMENTS, AGREEMENTS AND WAIVERS BY TENANT ARE A MATERIAL INDUCEMENT TO LANDLORD ENTERING INTO THIS LEASE.

5.6 Survival. Any obligations under this Section 5 which shall not have been paid at the expiration or earlier termination of the Term shall survive such expiration or earlier termination and shall be paid when and as the amount of same shall be determined and be due.

6. RIGHT OF FIRST OFFER

(a) Right of First Offer. Subject to the provisions of this Section 6, from and after the date on which the Building is 100% leased (the “ROFO Date”) and provided that (i) as of the date of the ROFO Notice (hereinafter defined), there is no Event of Default then continuing, (ii) as of the date of the ROFO Notice, Tenant meets the Occupancy Threshold, and (iii) as of the date on which the Available Space is expected to be delivered to Tenant, there remain at least three (3) years left in the Term (it being understood and agreed that Tenant shall have the right to elect to unconditionally exercise its option to extend the Term pursuant to Section 1.2 above, if any such right remains in force, if necessary to meet this precondition (provided that the determination of the Extension Term Base Rent shall occur as if Tenant provided its Extension Notice twelve (12) months prior to the expiration of the then-current term), Tenant shall have a continuous right of first offer to lease the other rentable areas of the Building (the “ROFO Space”) if, as and when the same shall become available for lease (as reasonably determined by Landlord, the “Available Space”), in their as-is condition, broom clean, free of personal property and decommissioned in accordance with reasonable industry standards, at then-fair market rent (based on such condition) (“ROFO FMR”), for a term co-terminus with the Term hereof, and otherwise upon the terms and conditions specified in the ROFO Notice. Tenant’s right of first offer under this Section 6 is further subject to all extension rights existing as of the ROFO Date.

(b) Offer and Acceptance Procedures for Right of First Offer.

(i) After Landlord reasonably determines that the ROFO Space is available for lease (meaning that it is or shall be available for lease within the next twelve-(12)-month period) and all of the preconditions to the right of first offer granted to Tenant in this Section 6 have been satisfied, Landlord shall deliver to Tenant a written notice offering to lease the Available Space to Tenant upon the terms and conditions set forth herein (the “ROFO Notice”). Tenant then shall have ten (10) days after receipt of the ROFO Notice to notify Landlord in writing whether Tenant will exercise its right to lease the Available Space upon the terms and conditions described in the ROFO Notice. If Tenant fails to notify Landlord in writing within such ten-(10)-day period that Xxxxxx accepts the offer contained in the ROFO Notice, or if Xxxxxx refuses in writing the offer contained in the ROFO Notice, Landlord shall have the right to lease the Available Space to any third-party tenant on the terms of the ROFO Notice provided that the net effective rent may be ten percent (10%) less than the net effective rent set forth in the ROFO Notice. As used herein, the term “net effective rent” shall mean the net present value of the rent, additional rent, and other charges that would be payable to Landlord under the terms of any proposed lease for and with respect to that portion of the term of the proposed lease equal to the period from the commencement date of such proposed lease through the expiration date, taking into account any construction allowance, the cost of any leasehold improvements proposed to be performed by Landlord, any free rent, and any other monetary inducements payable by Landlord under such proposed lease. If Landlord does not execute a lease with a third party with respect to the Available Space in question within twelve (12) months after the date on which Tenant refuses or is deemed to have refused the offer set forth in the applicable ROFO Notice, or if Landlord desires to offer the applicable Available Space on material terms different than previously described in the ROFO Notice (subject to the proviso regarding net effective rent set forth above), then Landlord must deliver a new ROFO Notice to Tenant in accordance with Section 6(a) above.

(ii) If Tenant timely notifies Landlord of its desire to lease the Available Space pursuant to this Section 6 (such notice, the “ROFO Acceptance”), Landlord shall submit to Tenant, and Tenant shall execute and deliver to Landlord within forty-five (45) days of receipt thereof, a reasonable form of lease amendment which incorporates all of the terms and conditions set forth in the ROFO Notice. Landlord and Tenant shall reasonably diligently negotiate such lease amendment in good faith. If the determination of the ROFO FMR is to be determined in accordance with Section 6(b) (iii) below and the ROFO FMR has not been determined prior to the expiration of such forty-five-(45)-day period, then the parties shall execute the lease amendment with the base rent amounts blank and deliver such executed originals into escrow with Landlord’s counsel. Notwithstanding anything to the contrary, the failure by

either party (or both parties) to execute such lease amendment shall not be deemed to nullify, cancel, modify or otherwise affect Tenant’s binding acceptance (as evidenced by the ROFO Acceptance) of the offer set forth in the ROFO Notice.

(iii) If Tenant timely provides the ROFO Acceptance and indicates in such ROFO Acceptance that Tenant (A) rejects Landlord’s determination of ROFO FMR, (B) desires to submit the matter to arbitration, and (C) identifies Tenant’s Appraiser, then the ROFO FMR shall be determined in accordance with the procedure set forth in this Section 6(b) (iii). In such event, within five (5) days after receipt by Landlord of Xxxxxx’s ROFO Acceptance, Landlord shall notify Tenant in writing of Landlord’s Appraiser. Landlord’s Appraiser and Tenant’s Appraiser shall then jointly select the Third Appraiser within ten (10) days of their appointment. All of the brokers/appraisers selected meet the requirements set forth in Section 1.2(c) above. Landlord’s Appraiser and Xxxxxx’s Appraiser shall deliver their determinations of the ROFO FMR to the Third Appraiser within five (5) days of the appointment of the Third Appraiser and the Third Appraiser shall render his or her decision within ten (10) days after receipt of both of the other two determinations of the ROFO FMR. The Third Appraiser’s decision shall be binding on both Landlord and Tenant. Each party shall bear the cost of its own appraiser and the cost of the Third Appraiser shall be paid by the party whose determination is not selected. If such determination is rendered after the 45-day period described in Section 6(b) (ii) above, then Landlord and Tenant shall jointly instruct Landlord’s counsel to insert into the escrowed amendments the ROFO FMR determined in accordance with this Section 6.1(b) (iii) and to release such completed amendments from escrow.

6.3 Termination of Rights. All rights of Tenant under this Section 6 shall terminate upon the expiration or earlier termination of the Term of this Lease.

6.4 Rights Personal to Tenant. Tenant may not assign, mortgage, pledge, encumber or otherwise transfer its interest or rights under this Section 6 other than to an assignee of Tenant, and any such purported transfer or attempt to transfer shall be void and without effect, shall terminate Tenant’s rights under this Section 6, and shall constitute an Event of Default under this Lease.

6.5 Time is of the Essence. Time is of the essence with respect to all aspects of this Section 6.

7. LETTER OF CREDIT

7.1 Amount. Contemporaneously with the execution of this Lease, Tenant shall deliver an irrevocable letter of credit to Landlord which shall (a) be in the amount specified in the Lease Summary Sheet and otherwise in the form attached hereto as Exhibit 5; (b) issued by a bank with a rating of A or better and otherwise reasonably acceptable to Landlord upon which presentment may be made in Boston, Massachusetts, by facsimile if to another jurisdiction, or otherwise at a location reasonably acceptable to Landlord (Landlord acknowledging that Silicon Valley Bank is acceptable for purposes of this clause (b)); and (c) be for a term of one (1) year, subject to extension in accordance with the terms hereof (the “Letter of Credit”). The Letter of Credit shall be held by Landlord, without liability for interest, as security for the faithful performance by Tenant of all of the terms, covenants and conditions of this Lease by the Tenant to be kept and performed during the Term. In no event shall the Letter of Credit be deemed to be a prepayment of Rent nor shall it be considered a measure of liquidated damages. Unless the Letter of Credit is automatically renewing, at least thirty (30) days prior to the maturity date of the Letter of Credit (or any replacement Letter of Credit), Tenant shall deliver to Landlord a replacement Letter of Credit which shall have a maturity date no earlier than the next anniversary of the Term Commencement Date or one (1) year from its date of delivery to Landlord, whichever is later.

7.2 Application of Proceeds of Letter of Credit. Upon an Event of Default, or if any proceeding shall be instituted by or against Tenant pursuant to any of the provisions of any Act of

Congress or State law relating to bankruptcy, reorganizations, arrangements, compositions or other relief from creditors (and, in the case of any proceeding instituted against it, if Tenant shall fail to have such proceedings dismissed within sixty (60) days) or if Tenant is adjudged bankrupt or insolvent as a result of any such proceeding, Landlord at its sole option may draw down all or a part of the Letter of Credit. The balance of any Letter of Credit cash proceeds shall be held in accordance with Section 7.5 below. Should the entire Letter of Credit, or any portion thereof, be drawn down by Landlord, Tenant shall, upon the written demand of Landlord, deliver a replacement Letter of Credit in the amount drawn, and Tenant’s failure to do so within ten (10) days after receipt of such written demand shall constitute an additional Event of Default hereunder. The application of all or any part of the cash proceeds of the Letter of Credit to any obligation or default of Tenant under this Lease shall not deprive Landlord of any other rights or remedies Landlord may have nor shall such application by Landlord constitute a waiver by Landlord.

7.3 Transfer of Letter of Credit. In the event that Landlord transfers its interest in the Premises, Tenant shall upon notice from and at no material cost to Landlord, deliver to Landlord an amendment to the Letter of Credit or a replacement Letter of Credit naming Xxxxxxxx’s successor as the beneficiary thereof. If Tenant fails to deliver such amendment or replacement within ten (10) business days after written notice from Landlord, Landlord shall have the right to draw down the entire amount of the Letter of Credit and hold the proceeds thereof in accordance with Section 7.5 below.

7.4 Credit of Issuer of Letter of Credit. In the event of a material adverse change in the financial position of any bank or institution which has issued the Letter of Credit or any replacement Letter of Credit hereunder, Landlord reserves the right to require that Tenant change the issuing bank or institution to another bank or institution reasonably approved by Landlord. Tenant shall, within ten (10) days after receipt of written notice from Landlord, which notice shall include the basis for Landlord’s reasonable belief that there has been a material adverse change in the financial position of the issuer of the Letter of Credit, replace the then-outstanding letter of credit with a like Letter of Credit from another bank or institution approved by Landlord.

7.5 Cash Proceeds of Letter of Credit. Landlord shall hold the balance of proceeds remaining after a draw on the Letter of Credit (referred to as the “Cash Security Deposit”) as security for Tenant’s performance of all its Lease obligations. After an Event of Default, Landlord may apply the Cash Security Deposit, or any part thereof, to Xxxxxxxx’s damages without prejudice to any other Landlord remedy. Landlord shall keep the Cash Security Deposit in an interest bearing account and any such interest shall be payable to Tenant. Landlord may co-mingle the Cash Security Deposit with Landlord’s funds. If Landlord conveys its interest under this Lease, the Cash Security Deposit, or any part not applied previously, may be turned over to the grantee in which case Tenant shall look solely to the grantee for the proper application and return of the Cash Security Deposit. So long as the Property is subject to a Mortgage, Landlord shall cause its first Mortgagee to hold any Cash Security Deposit, subject to the terms of this Section 7.

7.6 Return of Security Deposit or Letter of Credit. Should Tenant comply with all of such terms, covenants and conditions and promptly pay all sums payable by Tenant to Landlord hereunder, the Cash Security Deposit and/or Letter of Credit or the remaining proceeds therefrom, as applicable, shall be returned to Tenant within forty-five (45) days after the end of the Term, less any portion thereof which may have been utilized by Landlord to cure any default or applied to any actual damage suffered by Landlord.

7.7 Reduction in Letter of Credit. On the condition (the “Reduction Condition”) that as of the Effective Reduction Date, as hereinafter defined, there then exists no uncured Event of Default by Tenant under the Lease, then upon the date (the “Effective Reduction Date”) that Tenant executes an initial public offering, the amount of the Letter of Credit may, at Tenant’s election, be reduced to $1,186,462.50 (“Reduced Letter of Credit Amount”).

If the Reduction Condition is satisfied, Tenant may give Landlord written notice (the “Reduction Notice”) so notifying Landlord, together with evidence, reasonably satisfactory to Landlord, of Tenant’s status as a publicly traded company together with: (i) a Substitute Letter of Credit in the applicable reduced amount, in form satisfying the requirements of this Section 7, or (ii) an amendment to the existing Letter of Credit, in form and substance reasonably acceptable to Landlord, reducing the amount of the existing Letter of Credit to the Reduced Letter of Credit Amount. If Tenant delivers to Landlord a Substitute Letter of Credit satisfying the foregoing requirements, as aforesaid, then Landlord shall exchange the existing Letter of Credit which Landlord is then holding for such Substitute Letter of Credit within ten (10) business days after Xxxxxxxx receives such Substitute Letter of Credit to Landlord. If Landlord declines to reduce the Letter of Credit based upon the fact that any of the Reduction Condition have not been satisfied, but Tenant subsequently satisfies the Reduction Condition, then Tenant may submit a new Reduction Notice to Landlord for the reduction in the Letter of Credit in accordance with the provisions of this Section 7.7.

In no event shall the Letter of Credit ever be less than $1,186,462.50. The Letter of Credit, as it may be reduced in accordance with the foregoing, shall continue to be held by Landlord throughout the Term of the Lease, as it may be extended hereunder.

8. NO SECURITY INTEREST IN TENANT’S PROPERTY. Landlord hereby waives any right to claim a security interest or lien right in Tenant’s Property (hereinafter defined). Landlord hereby agrees to execute a waiver and agreement in Landlord’s commercially reasonable form for the benefit of any national banking association or institutional lender of Tenant (the “Secured Party”); provided, however, that it is understood and agreed by Xxxxxx that:

(a) the foregoing provisions shall not affect the prohibition set forth in Section 26.13 hereof;

(b) Landlord’s waiver shall only relate to items of Tenant’s Property which are specifically listed in such waiver and agreement the Secured Party shall give Landlord at least five (5) business days’ written notice prior to exercising any right which the Secured Party has to enter the Premises or the Building;

(d) the Secured Party shall not hold any auction or foreclosure sale in the Premises or the Building;

(e) the Secured Party shall either repair any damage to the Premises or the Building caused by the installation or removal of Tenant’s Property by anyone claiming by, through, or under the Secured Party or reimburse Landlord for any physical damage to the Premises actually caused by the installation or removal of Tenant’s Property;

(f) the removal of any of the Tenant’s Property from the Premises or the Building shall be completed in a manner that does not damage or injure the Premises or Building;

(g) if Tenant’s Property is not removed from the Premises on or before the expiration or prior termination of the Lease, the provisions of Section 21.2 of this Lease shall apply; and

(h) The Secured Party shall defend, indemnify and hold Landlord, Xxxxxxxx’s managing agent, and their respective partners, officers, directors, successors and assigns, harmless from and against any and all claims, actions, damages, costs, expenses (including reasonable attorneys’ fees) for personal property damage or personal injury arising from the Secured Party’s entry in the Premises

and the Building.

Tenant shall, at Tenant’s sole cost and expense, maintain and keep in good order, condition and repair the metering equipment used to measure electricity furnished to the Premises and any equipment exclusively serving the same. Tenant shall pay to Landlord the full amount of any charges attributable to such check meter (without mark-up to Landlord), based on Landlord’s reading of such check meter, on or before the later to occur of the due date therefor or 30 days following delivery of an invoice for such costs from Landlord.

Tenant shall pay all charges for gas furnished to the Premises and/or any equipment exclusively serving the Premises as Additional Rent, based on separate check meters installed by Tenant as part of Tenant’s Work. Tenant shall, at Tenant’s sole cost and expense, maintain and keep in good order, condition and repair the metering equipment used to measure gas furnished to the Premises and any equipment exclusively serving the same. Tenant shall pay to Landlord the full amount of any charges attributable to such meter based on Landlord’s reading of such check meter (without mark-up to Landlord), on or before the later to occur of the due date therefor or 30 days following delivery of an invoice for such costs from Landlord.

9.4 Other Utilities. Subject to Landlord’s reasonable Rules and Regulations governing the same, Tenant shall obtain and pay, as and when due, for all other utilities and services consumed in and/or furnished to the Premises, together with all taxes, penalties, surcharges and maintenance charges pertaining thereto.

9.5 Interruption or Curtailment of Utilities.

(a) When necessary by reason of accident or emergency, or for repairs, alterations, replacements or improvements which in the reasonable judgment of Landlord are desirable or necessary to be made, Landlord reserves the right (“Landlord’s Service Interruption Right”), in accordance with the provisions of this Section 9.5(a), to interrupt, curtail, or stop (i) the furnishing of hot and/or cold water, and (ii) the operation of the plumbing and electric systems (Landlord agreeing to use commercially reasonable efforts to (A) minimize the duration of any such interruption and (B) schedule such interruptions that are planned by Landlord, if any, after Tenant’s normal business hours and outside of the operation of Tenant’s GMP manufacturing facility; if such duration is reasonably expected to be for greater than 24 hours during any of Tenant’s normal business hours (as defined in Section 2.4(a) above) or during the operation of Tenant’s GMP manufacturing facility, then Landlord shall provide alternate services during such period). Except in an emergency imminently threatening life or property, Landlord may exercise Landlord’s Service Interruption Right only after giving Tenant written notice at least the Minimum Notice Period, as hereinafter defined, prior to the commencement of the interruption,

curtailment or stoppage in question. The “Minimum Notice Period” shall be at least ten (10) business days, unless the interruption, curtailment or stoppage in question will not affect Tenant’s GMP manufacturing facility, in which event the Minimum Notice period shall be at least three (3) business days. Landlord shall exercise reasonable diligence to eliminate the cause of any such interruption, curtailment, stoppage or suspension, but there shall be no diminution or abatement of Rent or other compensation due from Landlord to Tenant hereunder, nor shall this Lease be affected or any of Tenant’s obligations hereunder reduced, and Landlord shall have no responsibility or liability for any such interruption, curtailment, stoppage, or suspension of services or systems.

(b) Notwithstanding anything to the contrary in this Lease contained, if the Premises are rendered untenantable, in whole or in part (including without limitation by Tenant’s inability to conduct GMP manufacturing processes), due to the failure of Landlord to (i) provide any of Landlord’s Services, or (ii) Landlord’s failure to provide reasonable means of access or egress to/from the Premises or to perform its repair or maintenance obligations (such failures of Landlord being collectively referred to herein as “Landlord’s Interruption Causes”), such that, in either event, for the duration of the Interruption Cure Period (hereinafter defined), the continued operation in the ordinary course of Tenant’s business in any portion of the Premises (the “Affected Portion”) is materially and adversely affected and if Tenant ceases to use the Affected Portion in the ordinary course as the direct result of such lack of service or failure, then, provided that Landlord’s inability to cure such condition is not caused by the negligence or willful misconduct of any of the Tenant Parties, Base Rent, and Additional Rent on account of Operating Costs and Taxes shall be abated in proportion to such untenantability until the day such condition is completely corrected commencing on the first (1st) day after such Interruption Cure Period. For purposes hereof, the “Interruption Cure Period” shall be defined as (A) three (3) consecutive business days after Landlord’s receipt of written notice from Tenant of the condition causing the lack of service in the Affected Portion or lack of reasonable means of access/egress to/from the Premises, or (B) ten (10) consecutive business days after receipt of written notice from Tenant of the Landlord default in its repair and maintenance obligations (which written notice shall indicate that such default is causing such material and adverse effects on Tenant’s business operations in the ordinary course) (such notice by Tenant to Landlord under subsection (A) or (B), the “Interruption Notice”) (The foregoing right to receive an abatement of rent is referred to herein as the “Service Interruption Rent Abatement Right”). If the Interruption Notice indicates that the interruption event giving rise to a rent abatement pursuant to this paragraph materially and adversely interferes with Tenant’s use of at least 50% of the Premises (as measured in rentable square feet) or a portion of the Premises necessary to conduct Tenant’s research and development or light manufacturing uses substantially in the ordinary course, and, despite Tenant’s good faith efforts to take reasonable prudent measures and safeguards to avoid such interference and/or effects, such event materially and adversely interferes with Tenant’s use of at least 50% of the Premises (as measured in rentable square feet) or portion of the Premises necessary to conduct Tenant’s research and development or light manufacturing uses substantially in the ordinary course for a period of at least three hundred sixty-five (365) consecutive days after the Interruption Notice, then provided that Landlord’s inability to cure such condition is not caused by the negligence or willful misconduct of any of the Tenant Parties, Tenant may elect to terminate this Lease upon at least thirty (30) days’ written notice to Landlord; provided, however, if such interruption event ceases within such 30 day period, then Tenant’s termination notice shall be null and void. The provisions of this Section 9.5(b) shall not apply in the event of Casualty or Taking (which shall be governed by Section 15 below).

9.6 Landlord’s Services. Subject to reimbursement to the extent provided pursuant to Section 5.2 above, Landlord shall provide the services described in Exhibit 6 attached hereto and made a part hereof (“Landlord’s Services”).

10. MAINTENANCE AND REPAIRS

10.1 Maintenance and Repairs by Texxxx. Tenant shall keep neat and clean and free of insects, rodents, vermin and other pests and in good repair, order and condition the Premises, including

without limitation the entire interior of the Premises, all electronic, phone and data cabling and related equipment that is installed by or for the exclusive benefit of the Tenant (whether located in the Premises or other portions of the Building), all fixtures, equipment and lighting therein, electrical equipment wiring, doors, non-structural walls, and floor coverings, reasonable wear and tear and damage by Casualty excepted. Tenant shall be solely responsible, at Tenant’s sole cost and expense, for the proper maintenance of all building systems, life-safety, sanitary, electrical, heating, air conditioning, plumbing, security or other systems and of all equipment and appliances to the extent exclusively serving the Premises. Notwithstanding the foregoing: (i) Landlord shall perform the replacement of the elevator system during the Term, if necessary, and (ii) Tenant shall pay the cost of such replacement as part of Operating Costs in accordance with Section 5.2, except that: (x) Tenant’s Share of such costs shall be 100%, and (y) such replacement cost shall be amortized over the useful life of the replaced elevator system as determined in accordance with GAAP, together with interest accruing on the amount of such replacement cost over the period of such amortization the Capital Expenditure Interest Rate, as defined in Section 5.2(b). Tenant shall make such payments to Landlord at the same time and in the same manner as Tenant pays Tenant’s Share of Operating Expenses to Landlord pursuant to Section 5 of the Lease. Tenant agrees to provide regular maintenance by contract with a reputable qualified service contractor for the heating and air conditioning equipment servicing the Premises. Such maintenance contract and contractor shall be subject to Landlord’s reasonable approval. Tenant, at Laxxxxxx’s request, shall at reasonable intervals provide Landlord with copies of such contracts and maintenance and repair records and/or reports. To the extent that Landlord’s obligations under this Section 10.1 require Tenant to repair or maintain any elements of the Landlord’s Work, Landlord shall assign to Tenant any contractor or manufacturer’s warranties and guarantees for the same, provide Tenant with a copy of such warranties and guarantees, and cooperate with Tenant in such manner as Tenant may reasonably request, in order to enable Tenant to enforce the same.

10.2 Maintenance and Repairs by Landlord. Except as otherwise provided in Section 15, and subject to Tenant’s obligations in Section 10.1 above, Landlord shall maintain and keep in good condition, consistent with first class office and laboratory buildings, the components of the Building constructed by Landlord or its predecessors-in-interest, including the master fire alarm panel, Landlord’s Work, Building foundation, the roof and roof systems, Building structure, exterior wall system, façade, weight bearing walls, windows, structural floor and ceiling slabs and columns and the common components of life-safety, sanitary, electrical, heating, air conditioning, plumbing, security, mechanical, and other Building systems. In addition, Landlord shall be responsible for the replacement of the elevator system, if necessary during the Term, and shall operate and maintain the Common Areas in substantially the same manner as comparable first class buildings in the vicinity of the Premises.

10.3 Accidents to Sanitary and Other Systems. Tenant shall give to Landlord prompt notice of any fire or accident in the Premises or in the Building and of any damage to, or defective condition in, any part or appurtenance of the Building including, without limitation, sanitary, electrical, ventilation, heating and air conditioning or other systems located in, or passing through, the Premises (provided that it shall not be a default of Tenant if it fails to do so). Except as otherwise provided in Section 15, and subject to Tenant’s obligations in Section 10.1 above, such damage or defective condition shall be remedied by Landlord with reasonable diligence, but, subject to Section 14.5 below, if such damage or defective condition was caused by any of the Tenant Parties, the cost to remedy the same shall be paid by Tenant.

10.4 Floor Load—Heavy Equipment. Tenant shall not place a load upon any floor of the Premises exceeding the floor load per square foot of area which such floor was designed to carry (i.e., 125 pounds per square foot for the first floor of the Building and 100 pounds per square foot for the second floor of the Building) and which is allowed by Legal Requirements. Landlord reserves the right to prescribe the weight and position of all safes, heavy machinery, heavy equipment, freight, unusually bulky matter or fixtures (collectively, “Heavy Equipment”), which shall be placed so as to distribute the weight. Heavy Equipment shall be placed and maintained by Tenant at Tenant’s expense in settings

sufficient in Landlord’s reasonable judgment to absorb and prevent vibration, noise and annoyance. Tenant shall not move any Heavy Equipment into or out of the Building without giving Landlord prior written notice thereof and observing all of Landlord’s Rules and Regulations with respect to the same. If such Heavy Equipment requires special handling, Texxxx xgrees to employ only persons holding a Master Rixxxx’s License to do said work, and that all work in connection therewith shall comply with Legal Requirements. Any such moving shall be at the sole risk and hazard of Tenant and Tenant will defend, indemnify and save Landlord and Landlord’s agents (including without limitation its property manager), contractors and employees (collectively with Landlord, the “Landlord Parties”) harmless from and against any and all claims, damages, losses, penalties, costs, expenses and fees (including without limitation reasonable legal fees) (collectively, “Claims”) resulting directly or indirectly from such moving, except, subject to Section 14.5, to the extent resulting from Laxxxxxx’s negligence or willful misconduct. Proper placement of all Heavy Equipment in the Premises shall be Tenant’s responsibility.

11. ALTERATIONS AND IMPROVEMENTS BY TENANT

11.1 Landlord’s Consent Required. Tenant shall not make any alterations, decorations, installations, removals, additions or improvements (collectively with Tenant’s Work, “Alterations”) in or to the Premises without Landlord’s prior written approval of the contractor(s), written plans and specifications and a time schedule therefor, which approval of contractor(s) and schedule shall not be unreasonably withheld, conditioned or delayed (and shall not require Tenant to conduct such Alterations after normal business hours or on weekends except as otherwise expressly required pursuant to this Lease or as may be required pursuant to Section 11.3 below). Notwithstanding anything to the contrary, in no event shall any Alterations involve the removal of any improvements made by, or paid for by, Landlord without Landlord’s prior approval in Landlord’s sole discretion. Landlord shall respond to any request for approval of Alterations within ten (10) business days after receipt of the foregoing required information and shall promptly notify Tenant if any submission is incomplete. Notwithstanding the foregoing, Laxxxxxx’s consent shall not be required with respect to any Alterations that are purely decorative in nature nor with respect to non-structural Alterations costing less than $250,000 in any one instance (and $750,000 in the aggregate per year) so long as such Alterations do not materially adversely affect the roof, Building systems or Building exterior (each, a “Permitted Alteration”), provided Tenant shall provide Landlord with reasonably detailed written notice thereof. Landlord reserves the right to require that Tenant use Landlord’s preferred vendor(s) for any Alterations that involve roof penetrations, alarm tie-ins, sprinklers, fire alarm and other life safety equipment, provided that such vendors are available at commercially reasonable rates. Tenant shall not make any amendments or additions to plans and specifications (other than minor amendments in the nature of field changes) approved by Landlord without Landlord’s prior written consent (the standard of which consent shall be governed by the provisions of this Section 11). Laxxxxxx’s approval of Alterations shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, Landlord may withhold its consent in its sole discretion (a) to any Alteration to or affecting the roof (other than the Rooftop Premises) and/or materially and adversely affecting any building systems, (b) with respect to matters of aesthetics relating to Alterations to or affecting the exterior of the Building, and (c) to any Alteration adversely affecting the Building structure, with Tenant being obligated to provide Landlord with reasonable evidence that such Alteration does not adversely affect any portion of the Building structure. Tenant shall be responsible for all elements of the design of Tenant’s plans (including, without limitation, compliance with Legal Requirements, functionality of design, the structural integrity of the design, the configuration of the Premises and the placement of Tenant’s furniture, appliances and equipment), and Landlord’s approval of Texxxx’s plans shall in no event relieve Tenant of the responsibility for such design. Landlord shall provide Tenant with copies of Landlord Work Plans and all other plans for the Building in Landlord’s possession or control. Landlord shall have no liability or responsibility for any claim, injury or damage alleged to have been caused by the particular materials (whether building standard or non-building standard), appliances or equipment selected by Tenant in connection with any work performed by or on behalf of Texxxx. Except as otherwise expressly set forth herein, all Alterations shall be done at Tenant’s sole cost and expense and at such times and in such manner as Landlord may from time to time

reasonably designate (provided that Tenant shall not be required to conduct such Alterations after normal business hours or on weekends except as otherwise expressly required pursuant to Section 11.2 or as may be required pursuant to Section 11.3). Subject to the provisions of this Section 11.1, if Tenant makes any Alterations that require unusual expense to readapt the Premises to normal use as an office, light manufacturing, and research and development facility (“Specialty Alterations”) (and expressly excluding any non-structural Alterations to the office areas of the Premises), then Landlord may elect to require Tenant at the expiration or sooner termination of the Term to remove such Specialty Alterations and repair any damage to the Premises caused by such removal (which election shall be made at the time of Landlord’s approval of such Alterations). Without limiting the foregoing, Alterations associated with Tenant’s light manufacturing operations in the Premises, including, without limitation, any mezzanine or catwalk installed in the Premises as part of the Tenant’s Work (collectively “Light Manufacturing Alterations”) may, at Landlord’s election, be deemed to be Specialty Alterations. Notwithstanding the foregoing, Tenant shall not be required to remove, upon the expiration or earlier termination of the Lease, Alterations of the nature shown or otherwise described on Exhibit 15 (the “Alterations Which Are Not Specialty Alterations”) except as indicated thereon. Tenant shall provide Landlord with reproducible record drawings (in CAD format) of all Alterations susceptible to the creation of record drawings within sixty (60) days after completion thereof. During the Term only, Tenant shall be treated as the owner of all Alterations for all purposes under the Lease, including but not limited to the depreciation of such Alterations.

11.2 After-Hours. Landlord and Texxxx xecognize that to the extent Tenant elects to perform some or all of the Alterations during times other than normal construction hours (i.e., Monday - Friday, 7:00 a.m. to 6:00 p.m., excluding holidays), Landlord may need to make arrangements to have supervisory personnel on site. Accordingly, Landlord and Tenant agree as follows: Tenant shall give Landlord at least two (2) business days’ prior written notice of any time outside of normal construction hours when Tenant intends to perform any Alterations (the “After-Hours Work”). In addition, if construction during normal construction hours unreasonably disturbs other tenants of the Building, in Laxxxxxx’s sole discretion, Landlord may require Tenant to stop the performance of Alterations during normal construction hours and to perform the same after hours. From and after the Execution Date, Landlord shall include substantially similar provisions in any other leases at the Building and shall not enforce such provisions in a discriminatory manner.

11.3 Harmonious Relations. Tenant agrees that it will not, either directly or indirectly, use any contractors and/or materials if their use creates, or is reasonably expected to create, any difficulty, whether in the nature of a labor dispute or otherwise (including, without limitation, picketing), with other contractors and/or labor engaged by Tenant or Landlord or others in the construction, maintenance and/or operation of the Building, the Property or any part thereof (Landlord acknowledging that the use of union carpenters shall not be deemed to be a default under this sentence, unless any difficulty with other contractors and/or labor engaged by Texxxx, Landlord or others occurs by reason of Tenant’s use of union carpenters). In the event of any such difficulty, upon Laxxxxxx’s request, Tenant shall cause all contractors, mechanics or laborers causing such difficulty (including, without limitation, union carpenters) to leave the Property immediately. From and after the Execution Date, Landlord shall include substantially similar provisions in any other leases at the Building and shall not enforce such provisions in a discriminatory manner. Tenant expressly acknowledges that the contractor engaged by Laxxxxxx xo perform Landlord’s Base Building Work is a non-union contractor, and Texxxx xurther assures Landlord that Texxxx’s contractor will not cause any disruption or interference in the performance of Laxxxxxx’s Base Building Work by Laxxxxxx’s contractor as a result of said contractor’s non-union status.

11.4 Liens. No Alterations shall be undertaken by Tenant unless (i) Tenant obtains statutory lien waivers from all contractors for such Alteration as such work progresses (Landlord agreeing however, that, Tenant will not be required to obtain lien waivers from any contractor who is performing work for a cost which does not exceed $25,000); and (ii) with respect to work (excluding Tenant’s Work performed by, through or under The Richmond Group, Inc.) in excess of $600,000 in the aggregate

(which amount shall be increased to $1,000,000 if Tenant or any Unconditional Guarantor, as defined in Section 7.7,under this Lease is a publicly traded entity on a nationally recognized stock exchange), Texxxx xas procured appropriate surety payment and performance bonds which shall name Landlord as an additional obligee and has filed xxxx xxxx(s) (in jurisdictions where available) on behalf of such contractors. Any mechanic’s lien filed against the Premises or the Building for work claimed to have been done for, or materials claimed to have been furnished to, Tenant shall be discharged by Tenant within fifteen (15) days after notice thereof, at Texxxx’s expense by filing the bond required by law or otherwise.

11.5 General Requirements. Unless Landlord and Tenant otherwise agree in writing, Tenant shall (a) procure or cause others to procure on its behalf all necessary permits before undertaking any Alterations in the Premises (and provide copies thereof to Landlord); (b) perform all of such Alterations in a good and workmanlike manner, employing materials of good quality and in compliance with Landlord’s construction Rules and Regulations, all insurance requirements of this Lease and Legal Requirements; and (c) defend, indemnify and hold the Landlord Parties harmless from and against any and all Claims occasioned by or growing out of the performance of such Alterations. Tenant shall cause contractors employed by Tenant to (i) carry Worker’s Compensation Insurance in accordance with statutory requirements, (ii) carry Automobile Liability Insurance and Commercial General Liability Insurance (A) naming Landlord as an additional insured, and (B) covering such contractors on or about the Premises in the amounts stated in Section 14 hereof or in such other reasonable amounts as Landlord shall require, and (iii) cause such contractors submit binders or other evidence of insurance evidencing such coverage to Landlord prior to the commencement of any such Alterations.

12. SIGNAGE

12.1 Restrictions. Tenant shall have the right to install Building standard signage identifying Tenant’s business at the entrance to the Premises, which signage shall be subject to Landlord’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed so long as it complies with the signage guidelines attached hereto as Exhibit 10 (the “Signage Guidelines”)). Subject to the foregoing, and subject to Section 12.2 below, Tenant shall not place or suffer to be placed or maintained on the exterior of the Premises, or any part of the interior visible from the exterior thereof, any sign, banner, advertising matter or any other thing of any kind (including, without limitation, any hand-lettered advertising), and shall not place or maintain any decoration, letter or advertising matter on the glass of any window or door of the Premises visible from the exterior of the Premises without first obtaining Landlord’s written approval. No signs may be put on or in any window or elsewhere if visible from the exterior of the Building. No blinds may be put on or in any window or elsewhere if visible from the exterior of the Building without Landlord’s reasonable prior consent.

12.2 Exterior Signage. Provided that and for so long as Tenant satisfies the Occupancy Condition, as defined in Section 1.2, Tenant shall have the right to erect and maintain one (1) sign on the exterior of the Building at the entrance to the Premises (the “Exterior Signage”), provided (i) the Exterior Signage complies with the Signage Guidelines and all Legal Requirements (and Tenant shall have obtained any necessary permits prior to erecting the Exterior Signage), (ii) the location of the Exterior Signage shall be subject to Landlord’s reasonable approval, (iii) the materials, design, lighting and method of installation of the Exterior Signage, and any requested changes thereto, shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed, and (iv) Tenant shall at all times maintain the Exterior Signage in good order, condition and repair and shall remove the Exterior Signage at the expiration or earlier termination of the Term hereof or upon Laxxxxxx’s written demand after the failure of Tenant to comply with the provisions of this Section 12.2, and shall repair any damage to the Building caused by the Exterior Signage or the installation or removal thereof. Tenant shall have the right, from time to time throughout the Term of this Lease, to replace its signage (if any) with signage which is equivalent to the signage being replaced, subject to all of the terms and conditions of this Section 12.2.

In addition to the Exterior Signage, provided that and for so long as Tenant meets the Occupancy Threshold, Landlord shall list Tenant on the multi-tenant Building monument signage the “Monument Signage”) that will be installed by Landlord as part of the Base Building Work and will be maintained by Landlord in a manner comparable to those listings provided to other tenants in the Building. In no event shall Landlord disapprove of the inclusion of Tenant corporate branding and logo (which may include the use of Tenant’s name) on any of Tenant’s Monument Signage. Neither Landlord nor any of its affiliates shall make or permit any improvements to the Property that would adversely affect the visibility of Exterior Signage installed by Tenant pursuant to this Section 12.2.

13. ASSIGNMENT, MORTGAGING AND SUBLETTING

13.1 Landlord’s Consent Required. Except as expressly otherwise set forth herein, Tenant shall not, without Laxxxxxx’s prior written consent, assign, sublet, mortgage, license, transfer or encumber this Lease or the Premises in whole or in part whether by changes in the control of Tenant (other than as the result of transfers of interests among parties holding a direct or indirect interest in Tenant), or permit the occupancy of all or any portion of the Premises by any person or entity other than Tenant’s employees (each of the foregoing, a “Transfer”). Any purported Transfer made without Laxxxxxx’s consent, if required hereunder, shall be void and confer no rights upon any third person, provided that if there is a Transfer, Landlord may collect rent from the transferee without waiving the prohibition against Transfers, accepting the transferee, or releasing Tenant from full performance under this Lease. No Transfer shall relieve Tenant of its primary obligation as party-Tenant hereunder, nor shall it reduce or increase Landlord’s obligations under this Lease. In no event shall the issuance of any beneficial interests in Tenant or any entity holding an interest in Tenant or the trading of any stock in any entity directly or directly holding an interest in Tenant on a nationally-recognized stock exchange be deemed to result in a Transfer hereunder.

13.2 Landlord’s Recapture Right

(a) Tenant shall, prior to entering into any Transfer (other than a Permitted Transfer (hereinafter defined)) for all or substantially all of the balance of the Term of this Lease and affecting fifty percent (50%) or more of the Premises (individually or in the aggregate with other Transfers (other than a Permitted Transfer) in effect) (such a Transfer, a “Material Transfer”), give a written notice (the “Recapture Notice”) to Landlord which: (i) states that Tenant desires to make a Material Transfer, (ii) identifies the affected portion of the Premises (the “Recapture Premises”), (iii) identifies the date on which the Material Transfer is proposed to take effect, and (iv) offers to Landlord to terminate this Lease with respect to the Recapture Premises. Landlord shall have ten (10) business days within which to respond to the Recapture Notice and, if Landlord accepts Texxxx’s Recapture Notice, then this Lease shall terminate with respect to the Recapture Premises effective on the proposed effective date of such Material Transfer as set forth in the Recapture Notice.

(b) If Tenant does not enter into a Transfer on the terms and conditions contained in the Recapture Notice on or before the date which is one hundred eighty (180) days after the earlier of: (x) the expiration of the ten-(10)-business day period specified in Section 13.2(a) above, or (y) the date that Landlord notifies Tenant that Landlord will not accept Tenant’s offer contained in the Recapture Notice, time being of the essence, then prior to entering into any Transfer after such one-hundred-eighty-(180)-day period, Tenant must deliver to Landlord a new Recapture Notice in accordance with Section 13.2(a) above.

(c) Notwithstanding anything to the contrary contained herein, if Landlord notifies Tenant that it accepts the offer contained in the Recapture Notice or any subsequent Recapture Notice, Tenant shall have the right, for a period of ten (10) days following receipt of such notice from Landlord, time being of the essence, to notify Landlord in writing that it wishes to withdraw such offer and this Lease shall continue in full force and effect.

13.3 Standard of Consent to Transfer. If Landlord does not timely give written notice to Tenant accepting a Recapture Offer or declines to accept the same, then Landlord agrees that, subject to the provisions of this Section 13, Landlord shall not unreasonably withhold, condition or delay its consent to a Transfer on the terms contained in the Recapture Notice to an entity which will use the Premises for the Permitted Uses and: (a) with respect to any assignment of this Lease or a sublet of all or substantially all of the Premises, has a tangible net worth and other financial indicators at least equal to Tenant’s as of the date of the Recapture Notice (or, if Tenant or any Unconditional Guarantor of this Lease is a publicly traded entity on a nationally recognized stock exchange, at least sufficient to meet such assignee or sublessee’s obligations under this Lease or such sublease, as applicable); and (b) has a business reputation compatible with the operation of a first-class combination laboratory, research, development and office building and in any event, shall grant or deny such consent within fifteen (15) business days after Tenant’s request for such consent.

13.4 Listing Confers no Rights. The listing of any name other than that of Tenant, whether on the doors of the Premises or on the Building directory, or otherwise, shall not operate to vest in any such other person, firm or corporation any right or interest in this Lease or in the Premises or be deemed to effect or evidence any consent of Landlord, it being expressly understood that any such listing is (except to the extent of Tenant’s express signage rights provided under Section 12) a privilege extended by Landlord revocable at will by written notice to Tenant.

13.5 Profits In Connection with Transfers. Tenant shall, within thirty (30) days of receipt thereof, pay to Landlord fifty percent (50%) of any rent, sum or other consideration to be paid or given in connection with any Transfer, either initially or over time, after deducting reasonable actual out-of-pocket legal and brokerage expenses incurred by Tenant, rent concessions, tenant improvement allowances, and other third party costs incurred by Tenant in connection with such Transfer and the depreciated value (in accordance with generally accepted accounting principles) of the cost of Alterations performed at Tenant’s expense to prepare the Premises for Tenant’s use and occupancy (i.e., amounts in excess of Landlord’s Contribution), prorated according to the fraction of rentable area of the Premises affected the Transfer, in excess of Rent hereunder as if such amount were originally called for by the terms of this Lease as Additional Rent.

13.6 Prohibited Transfers. Notwithstanding any contrary provision of this Lease, Tenant shall have no right to make a Transfer unless on both (i) the date on which Tenant notifies Landlord of its intention to enter into a Transfer and (ii) the date on which such Transfer is to take effect, Tenant is not in default of any of its obligations under this Lease (it being understood and agreed that if Tenant cures any default(s) within the applicable cure period(s) provided in Section 20 below, then Tenant shall thereafter be entitled to make the Transfer in question). Notwithstanding anything to the contrary contained herein, Xxxxxx agrees that in no event shall Tenant make a Transfer to (a) any government agency so long as no other portion of the Building is leased to a governmental agency; (b) any tenant, subtenant or occupant of other space in the Building provided that comparable space is then available for lease in the Building; or (c) any entity with whom Landlord shall have negotiated for space in the Property in the three (3) months immediately preceding such proposed Transfer.

13.7 Permitted Transfers.

(a) Notwithstanding anything to the contrary herein contained, Tenant shall have the right, without obtaining Landlord’s consent, to (i) make a Transfer to an Affiliate, and (ii) to assign all of its right, title and interest in and to the Premises pursuant to this Lease to a Successor, provided that, in the event of an assignment of Xxxxxx’s interest in this Lease (except as the result of a merger), such Affiliate or Successor, as the case may be, and Tenant execute and deliver to Landlord a commercially reasonable assignment and assumption agreement whereby such Affiliate or Successor, as the case may be, shall agree to be independently bound by and upon all of the covenants, agreements, terms, provisions and conditions set forth in this Lease on the part of Tenant to be performed, and whereby such Affiliate or

Successor, as the case may be, shall expressly agree that the provisions of this Section 13 shall, notwithstanding such assignment, continue to be binding upon it with respect to all future Transfers. Tenant shall deliver such assignment and assumption agreement to Landlord prior to the effective date of such assignment unless Tenant is contractually or legally prohibited from doing so, in which event such agreement shall be delivered to Landlord within ten (10) days after the effective date thereof. For the purposes hereof, an “Affiliate” shall be defined as any entity which is controlled by, is under common control with, or which controls Tenant. For the purposes hereof, a “Successor” shall be defined as any entity into or with which Tenant is merged or with which Tenant is consolidated or which acquires all or substantially all of Tenant’s stock or assets, or any other corporate reorganization of Tenant, provided that the surviving entity shall have a net worth and other financial indicators at least equal to Tenant’s immediately prior to such event.

(b) Notwithstanding any provision to the contrary in this Lease, occupancy of less than ten thousand (10,000) rentable square feet of the Premises by companies, firms or other entities (i) who are members of a group with whom Xxxxxx has a contractual or other relationship providing for cooperative or collaborative research or development work, who are or typically would be located by Tenant in one of its facilities, and/or (ii) in which Tenant has a beneficial interest and which are actively engaged in research activities using technology, techniques and/or equipment developed by Tenant (each such entity, an “Approved User”) shall not be a Transfer for the purposes of this Section 13 and shall be permitted without the necessity of obtaining Landlord’s consent thereto, but Tenant shall provide Landlord with prior written notice thereof (which notice shall include the identity of such entities, the number of square feet in occupancy by such entities and such other information reasonably required for financing, insurance and other risk management purposes, but which notice may otherwise be limited in detail to the extent required by applicable confidentiality agreements).

Notwithstanding the foregoing or anything herein to the contrary, in no event shall the use of the Premises by Approved Users under subparagraphs (b) and (c) of this Section exceed 10,000 rentable square feet in the aggregate at any one time.

installed anywhere outside of the Premises or within the Premises if it is visible from outside of the Premises.

(e) Notwithstanding the provisions of this Section 13.7, no transaction or series of transactions which are effected solely for the purpose of qualifying as a transaction which does not require Landlord’s consent (i.e. and thereby avoiding the operation of the provisions of this Section 13) shall be permitted pursuant to this Section 13.7.

(f) Transfers not requiring Landlord consent pursuant to this Section 13.7 are referred to herein as “Permitted Transfers.”

Tenant covenants and agrees that, to the maximum extent permitted by Legal Requirements, all of Tenant’s Property at the Premises shall be at the sole risk and hazard of Tenant, and that if the whole or any part thereof shall be damaged, destroyed, stolen or removed from any cause or reason whatsoever, no part of said damage or loss shall be charged to, or borne by, Landlord, except, subject to Section 14.5 hereof, to the extent such damage or loss is due to the negligence or willful misconduct of any of the Landlord Parties.

reasonable time after notice has been received by Landlord without Landlord having commenced to take all reasonable and practicable means to cure or correct such condition; and pending such cure or correction by Landlord, Tenant shall take all reasonably prudent temporary measures and safeguards to prevent any injury, loss or damage to persons or property. Notwithstanding the foregoing, in no event shall any of the Landlord Parties be liable for any property loss which is covered by insurance policies actually carried or required to be carried by this Lease; nor shall any of the Landlord Parties be liable for any such damage caused by other tenants or persons in the Building or caused by operations in construction of any private, public or quasi-public work. Nothing in this Section 14.4 shall derogate or diminish Landlord’s obligations under Section 10.2 above.

Landlord and Tenant each agrees to cause appropriate clauses to be included in its property insurance policies necessary to implement the foregoing provisions.

14.6 Tenant’s Acts—Effect on Insurance. Tenant shall not do or permit any Tenant Party to do any act or thing upon the Premises or elsewhere in the Building which will invalidate or be in conflict with any insurance policies covering the Building and the fixtures and property therein of which Xxxxxx has prior written notice (Landlord acknowledging that the use of the Premises for the Permitted Uses (as opposed to the manner of use of the Premises by Tenant or any Tenant Party) is not in violation of the provisions of this sentence. If by reason of the failure of Tenant to comply with the provisions hereof the insurance rate applicable to any policy of insurance shall at any time thereafter be higher than it otherwise would be, Tenant shall cease the applicable acts or reimburse Landlord upon demand for that part of any insurance premiums which shall have been charged because of such failure by Xxxxxx, together with interest at the Default Rate until paid in full, within ten (10) days after receipt of an invoice therefor.

14.7 Landlord’s Insurance. Landlord shall take out and maintain in force throughout the Term hereof, in a company or companies authorized to do business in the Commonwealth of Massachusetts: (a) property insurance on the Building (exclusive of Tenant’s Property, Tenant-Insured Improvements and personal property of, and alterations by, other tenants or occupants) in an amount equal to the full replacement value of the Building (exclusive of foundations and those items set forth in the preceding parenthetical in this sentence), covering fire, vandalism, malicious mischief, extended coverage and so-called “all risk”; (b) rental interruption insurance sufficient to cover at least twelve (12) months of rents from the Property and Landlord’s rental losses during such 12-moonth period, and (c) commercial general liability insurance against claims of bodily injury (including, without limitation, sickness, disease, and death resulting therefrom) and property damage which may be claimed to have occurred from and after the date any of the Tenant Parties shall first enter the Premises arising out of Landlord’s operation of the Property of not less than Two Million Dollars ($2,000,000). Landlord shall also carry umbrella liability coverage in an amount of no less than Ten Million Dollars ($10,000,000). Such liability policy shall also include contractual liability coverage covering Landlord’s liability assumed under this Lease under Section 14.2. The foregoing insurance may be maintained in the form of a blanket policy covering the Property as well as other properties owned by Landlord and Landlord’s affiliates. The insurance required pursuant this paragraph shall be effected with insurers with a rating of not less than “A-/VII” in the current Best’s Insurance Reports, and authorized to do business in the

Commonwealth of Massachusetts under valid and enforceable policies. Landlord’s insurance policies may include deductibles under its property insurance policies insuring the Property not exceeding a commercially reasonable amount (Tenant hereby agreeing that, as of the Term Commencement Date, $25,000 is a commercially reasonable deductible). Landlord shall deliver to Tenant certificates evidencing the coverage required hereunder upon Xxxxxx’s request.

15. CASUALTY; TAKING

15.1 Damage. If the Premises or any appurtenant areas of the Building or Property necessary to provide access to the Premises or services to, or rights of, Tenant as required hereunder (collectively, the “Restoration Areas”) are damaged in whole or part because of fire or other insured casualty (“Casualty”), or if the Restoration Areas are subject to a taking in connection with the exercise of any power of eminent domain, condemnation, or purchase under threat or in lieu thereof (any of the foregoing, a “Taking”), then unless this Lease is terminated in accordance with Section 15.2 below, Landlord shall, subject to the last sentence of this Section 15.1, restore the Restoration Areas to substantially the same condition as existed prior to such Casualty, or in the event of a partial Taking which affects the Restoration Areas, restore the remainder of the Restoration Areas not so Taken to substantially the same condition as is reasonably feasible. If any other portion of the Building is damaged by Casualty or Taking, then Landlord may elect not to restore the same so long as the affected portions of the Building (other than the Restoration Areas) are otherwise repaired in a manner consistent with first class office and laboratory use. If, in Landlord’s reasonable judgment, any element of the Tenant-Insured Improvements can more effectively be restored as an integral part of Landlord’s restoration of the Building or the Premises, such restoration shall also be made by Landlord, but at Tenant’s sole cost and expense (subject to the amount of insurance proceeds received by Tenant or that would have been received by Tenant had it been maintaining the coverages required under this Lease). Subject to rights of Mortgagees, Tenant Delays, Legal Requirements then in existence and to delays for adjustment of insurance proceeds or Taking awards, as the case may be, and instances of Force Majeure, Landlord shall use good faith efforts to obtain all required permits therefor and to thereafter promptly commence and diligently prosecute restoration so as to substantially complete restoration of the Premises within twelve (12) months after the date of the Casualty with respect to substantial reconstruction of at least 50% of the Building, or, within one hundred eighty (180) days after the date of the Casualty in the case of restoration of less than 50% of the Building. During such restoration, Landlord shall have the right to relocate Tenant’s Parking Spaces in accordance with Section 1.3(b) above. Upon substantial completion of such restoration by Landlord, Tenant shall use diligent efforts to complete restoration of the Premises to substantially the same condition as existed immediately prior to such Casualty or Taking, as the case may be, as soon as reasonably possible. Xxxxxx agrees to cooperate with Landlord in such manner as Landlord may reasonably request to assist Landlord in collecting insurance proceeds due in connection with any Casualty which affects the Restoration Areas. In no event shall Landlord be required to expend more than the Net (hereinafter defined) insurance proceeds Landlord receives for damage to the Premises and/or the Building or the Net Taking award attributable to the Premises and/or the Building. “Net” means the insurance proceeds or Taking award actually paid to Landlord (and not paid over to a Mortgagee) less all reasonable third party costs and expenses, including adjusters and attorney’s fees, of obtaining the same. In the fiscal year in which a Casualty occurs, there shall be included in Operating Costs Landlord’s deductible under its property insurance policy. Except as Landlord may elect pursuant to this Section 15.1, under no circumstances shall Landlord be required to repair any damage to, or make any repairs to or replacements of, any Tenant-Insured Improvements.

15.2 Termination Rights.

(a) Landlord’s Termination Rights. Landlord may terminate this Lease upon thirty (30) days’ prior written notice to Tenant if: (i) any material portion of the Building or all reasonable

means of access thereto is taken (other than a Taking for temporary use, as defined in Section 15.3 hereof); (ii) more than thirty-five percent (35%) of the Building is damaged by Casualty; (iii) if the estimated time to complete restoration, as provided to Tenant by Landlord within ninety (90) days following the occurrence of such Casualty (based on a good faith estimate by a qualified general contractor), exceeds twelve (12) months from the date of Casualty; or (iv) if the estimated cost of Landlord’s restoration obligations exceeds the amount of the insurance proceeds released by Landlord’s Mortgagee for such purpose by more than $1,000,000. Landlord shall not exercise its termination rights pursuant to this Section 15.2(a) unless Landlord is terminating the leases of all tenants at the Building.

(b) Tenant’s Termination Rights.

(i) If (A) this Lease is not terminated and Landlord fails to complete restoration of the Premises, base Building systems serving the same, reasonable means of access to the Premises and the parking areas serving Tenant (collectively, the “Primary Areas”) within the time frames and subject to the conditions set forth in Section 15.1 above, or (B) if the estimated time to complete restoration of the Primary Areas (as provided pursuant to the immediately preceding paragraph) exceeds the timeframes set forth in Section 15.1 above, then Tenant may terminate this Lease upon thirty (30) days’ written notice to Landlord; provided, however, that if Landlord completes such restoration within thirty (30) days after receipt of any such termination notice, such termination notice shall be null and void and this Lease shall continue in full force and effect.

(ii) In addition, if Xxxxxxxx’s Mortgagee does not release sufficient insurance proceeds to cover the cost of Landlord’s restoration obligations, then Landlord shall notify Tenant thereof. If such notice by Landlord does not include an agreement by Landlord to pay for the difference between the cost of such restoration and such released insurance proceeds, then Tenant may terminate this Lease by written notice to Landlord on or before the date that is thirty (30) days after such notice.

(iii) The remedies set forth in this Section 15.2 are Tenant’s sole and exclusive rights and remedies based upon Landlord’s failure to complete the restoration of the Premises as set forth herein.

(c) Either Party May Terminate. In the case of any Casualty or Taking affecting the Premises and occurring during the last twelve (12) months of the Term and the restoration of the Restoration Areas is estimated to take greater than twenty-five percent (25%) of the then-remaining Term, then either Landlord or Tenant shall have the option to terminate this Lease upon thirty (30) days’ written notice to the other. If this Lease is terminated as a result of any Casualty or Taking, Landlord shall promptly refund to Tenant any rent and other payments paid prior to such termination but relating to periods from and after such termination. Landlord shall not exercise its termination rights pursuant to this Section 15.2(c) unless Landlord terminates the leases of all tenants at the Building.

(d) Automatic Termination. In the case of a Taking of the entire Premises, then this Lease shall automatically terminate as of the date of possession by the Taking authority.

(e) Rent Abatement. Following any Casualty or Taking, the Rent under this Lease shall be equitably abated for the period of any restoration of the Premises and a reasonable means of access thereto and a reasonable additional period thereafter for the restoration of any Tenant-Insured Improvements, such abatement to be based on the portion of the Premises rendered untenantable on account of the Casualty or Taking.

15.3 Taking for Temporary Use. If the Premises are Taken for temporary use, this Lease and Tenant’s obligations, including without limitation the payment of Rent, shall continue and Tenant

shall be entitled to all of the proceeds of such temporary taking to the extent relating to periods of time within the Term. For purposes hereof, a “Taking for temporary use” shall mean a Taking of ninety (90) days or less.

15.4 Disposition of Awards. Except for any separate award for Tenant’s movable trade fixtures and relocation expenses (provided that the same may not reduce Landlord’s award), and unamortized leasehold improvements paid for by Tenant (i.e., in excess of Landlord’s Contribution and any other improvements paid for by Landlord), all Taking awards to Landlord or Tenant shall be Landlord’s property without Tenant’s participation, and Tenant hereby assigns to Landlord Tenant’s interest, if any, in such award. Tenant may pursue its own claim against the Taking authority.

16. ESTOPPEL CERTIFICATE. Tenant shall at any time and from time to time upon not less than ten (10) business days’ prior notice from Landlord, execute, acknowledge and deliver to Landlord a statement in writing certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications), and the dates to which Rent has been paid in advance, if any, stating whether or not, to the knowledge of Tenant, Landlord is in default in performance of any covenant, agreement, term, provision or condition contained in this Lease and, if so, specifying each such default, and such other facts as Landlord may reasonably request, it being intended that any such statement delivered pursuant hereto may be relied upon by any prospective purchaser of the Building or of any interest of Landlord therein, any Mortgagee or prospective Mortgagee thereof, any lessor or prospective lessor thereof, any lessee or prospective lessee thereof, or any prospective assignee of any mortgage thereof. Landlord shall at any time and from time to time upon not less than ten (10) business days’ prior notice from Tenant execute, acknowledge and deliver to Tenant a statement in writing certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications), and the dates to which Rent has been paid in advance, if any, stating whether or not, to the knowledge of Landlord, Tenant is in default in performance of any covenant, agreement, term, provision or condition contained in this Lease and, if so, specifying each such default, and such other facts as Tenant may reasonably request, it being intended that any such statement delivered pursuant hereto may be relied upon by any prospective Transferee, or any lender or prospective lender of any Tenant. Time is of the essence with respect to any such requested certificate, the parties hereby acknowledging the importance of such certificates in mortgage financing arrangements, prospective sales and the like. In the case of any discrepancy between the Lease and the Estoppel Certificate, the Lease shall govern.

17. HAZARDOUS MATERIALS

17.1 Prohibition. Tenant shall not, without the prior written consent of Landlord, bring or permit to be brought or kept in or on the Premises or elsewhere in the Building or the Property (i) any inflammable, combustible or explosive fluid, material, chemical or substance (except for standard office supplies stored in proper containers and Hazardous Materials in compliance with the following provisions of this Lease), provided that Tenant shall not be entitled to store more than Tenant’s Share of inflammable materials allowable pursuant to applicable Legal Requirements at the Building without obtaining a license therefor (which License shall be held in the name of Landlord but obtained with the cooperation of Landlord and Tenant); and (ii) any Hazardous Material (hereinafter defined), other than the types and quantities of Hazardous Materials which are listed on Exhibit 7 attached hereto or otherwise required in the normal operation of Tenant’s business (“Tenant’s Hazardous Materials”) or otherwise, provided that the same shall at all times be brought upon, kept or used in so-called ‘control areas’ (the number and size of which shall be reasonably determined by Landlord, but in no event shall the Premises be required to contain less than Tenant’s Share of the fire control and chemical storage areas permitted in the Building throughout the Term) and in accordance with all applicable Environmental Laws (hereinafter defined) and prudent environmental practice and (with respect to medical waste and so-called “biohazard” materials) good scientific and medical practice. Notwithstanding the foregoing, Tenant shall be allocated

two (2) of the four (4) first (1st) floor control areas in accordance with the 9th Edition of the State Building Code 780 CMR Table 414.2.2 and shall be allowed to possess up to the allowable limits of Hazardous Materials as defined in 780 CMR Table 307.1. Tenant shall be responsible for assuring that all laboratory uses are adequately and properly vented. On or before each anniversary of the Base Rent Commencement Date, and on any earlier date during the twelve-(12)-month period on which Tenant intends to materially increase the number or quantity of any Hazardous Material to the list of Tenant’s Hazardous materials, and additionally at Landlord’s request (made no more often than once per Rent Year) or in connection with a sale or financing of all or any portion of Landlord’s interest in the Property, Tenant shall submit to Landlord an updated list of the types and quantities of Tenant’s Hazardous Materials. Landlord shall have the right, from time to time, to inspect the Premises for compliance with the terms of this Section 17.1 subject to the provisions of Section 2.4 of this Lease. Notwithstanding the foregoing, with respect to any of Tenant’s Hazardous Materials which Tenant does not properly handle, store or dispose of in compliance with all applicable Environmental Laws (hereinafter defined), prudent environmental practice and (with respect to medical waste and so-called “biohazard materials) good scientific and medical practice, Tenant shall, upon written notice from Landlord, no longer have the right to bring such material into the Building or the Property until Tenant has demonstrated, to Landlord’s reasonable satisfaction, that Tenant has implemented programs to thereafter properly handle, store or dispose of such material. In the event Tenant desires to use radioactive materials during the Term of this Lease, Tenant shall so notify Landlord and Tenant shall be required, as a condition to such use, to obtain additional insurance coverages customarily carried by tenants of similar life science where similar quantities of radioactive materials will be used (provided that, if Tenant is publicly traded entity with a net worth of at least $50,000,000, Tenant may self-insure any such risk).

17.2 Environmental Laws. For purposes hereof, “Environmental Laws” shall mean all laws, statutes, ordinances, rules and regulations of any local, state or federal governmental authority having jurisdiction concerning environmental, and human health and safety matters, including but not limited to any discharge by any of the Tenant Parties into the air, surface water, sewers, soil or groundwater of any Hazardous Material (hereinafter defined) whether within or outside the Premises, including, without limitation (a) the Federal Water Pollution Control Act, 33 U.S.C. Section 1251 et seq., (b) the Federal Resource Conservation and Recovery Act, 42 U.S.C. Section 6901 et seq., (c) the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. Section 9601 et seq., (d) the Toxic Substances Control Act of 1976, 15 U.S.C. Section 2601 et seq., and (e) Chapter 21E of the General Laws of Massachusetts. Tenant, at its sole cost and expense, shall comply with (i) Environmental Laws, and (ii) any rules, requirements and safety procedures of the Massachusetts Department of Environmental Protection, the City of Framingham and the reasonable requirements of any insurer of the Building or the Premises (provided that the same are consistent with those applicable to similar uses in similar buildings in the areas) with respect to Tenant’s use, storage and disposal of any Hazardous Materials.

17.3 Hazardous Material Defined. As used herein, the term “Hazardous Material” means asbestos, oil or any hazardous, radioactive or toxic substance, material or waste or petroleum derivative which is or becomes regulated by any Environmental Law, including without limitation live organisms used in Tenant’s research and development or manufacturing processes, viruses and fungi used in Tenant’s research and development or manufacturing processes, medical waste and any so-called “biohazard” materials. The term “Hazardous Material” includes, without limitation, oil and/or any material or substance which is (i) designated as a “hazardous substance,” “hazardous material,” “oil,” “hazardous waste” or toxic substance under any Environmental Law.

17.4 Testing. If Landlord reasonably believes that any Hazardous Materials have been released on, in, under or at the Premises in violation of this Lease or any Legal Requirement, Landlord shall have the right to conduct appropriate tests of the Premises or any portion thereof to demonstrate that Hazardous Materials are present or that contamination has occurred due to the acts or omissions of any of the Tenant Parties. Tenant shall pay all reasonable costs of such tests if such tests reveal that Hazardous

Materials exist at the Premises in violation of this Lease or any Legal Requirement. If any Mortgagee or governmental authority requires testing to determine whether there has been any release of Hazardous Materials and such testing is required as a result of the acts or omissions of any of the Tenant Parties, then Tenant shall reimburse Landlord upon demand, as additional rent, for the reasonable costs thereof, together with interest at the Default Rate until paid in full. Further, Landlord shall have the right to request from Tenant a report from a third party safety consultant engaged by Tenant which is reasonably acceptable to Landlord, or, if Tenant does not obtain and deliver such a report to Landlord, within ten (10) Business Days of written request from Landlord and an additional five-(5)-Business-Day period following notice from Landlord, to cause a third party consultant reasonably approved by Xxxxxx and retained by Landlord (“Landlord’s Safety Consultant”) to review, but not more than once in any calendar year, Xxxxxx’s lab operations, procedures and permits to ascertain whether or not Tenant is complying with law and adhering to best industry practices, provided that such consultant enters into a non-disclosure agreement reasonably satisfactory to Tenant and Tenant is provided a copy of any such report. Xxxxxx agrees to cooperate in good faith, at no expense to Tenant (subject to the next following sentence), with any such review and to provide to such consultant any information requested by such consultant and reasonably required in order for such consultant to perform such review, but nothing contained herein shall require Tenant to provide proprietary or confidential information to such consultant. Landlord shall bear the cost of Landlord’s Safety Consultant, unless it is determined that, based upon the inspection of Landlord’s Safety Consultant that Tenant is in breach of its obligations under this Section 17, in which event Tenant shall be responsible for the costs incurred by Landlord in engaging Xxxxxxxx’s Safety Consultant pursuant to this Section 17.4.

17.5 Indemnity; Remediation.

(a) Tenant hereby covenants and agrees to indemnify, defend and hold the Landlord Parties harmless from and against any and all Claims against any of the Landlord Parties arising out of contamination of any part of the Property or other adjacent property, which contamination arises as a result of: (i) the presence of Hazardous Material in the Premises, the presence of which is caused by any act or omission of any of the Tenant Parties, or (ii) from a breach by Tenant of its obligations under this Section 17. This indemnification of the Landlord Parties by Tenant includes, without limitation, reasonable third party costs incurred in connection with any investigation of site conditions or any cleanup, remedial, removal or restoration work or any other response action required by any federal, state or local governmental agency or political subdivision because of Hazardous Material present in the soil, soil vapor, or ground water on or under, or any indoor air in the Building based upon the circumstances identified in the first sentence of this Section 17.5. The indemnification and hold harmless obligations of Tenant under this Section 17.5 shall survive the expiration or any earlier termination of this Lease. Without limiting the foregoing, if the presence of any Hazardous Material in the Building or otherwise in the Property is caused or, where any third party is under the control of a Tenant Party, permitted by any of the Tenant Parties and results in any contamination of any part of the Property or any adjacent property, Tenant shall promptly take all actions at Tenant’s sole cost and expense as are necessary to return the Property and/or the Building or any adjacent property to their condition as of the date of this Lease, provided that Tenant shall first obtain Landlord’s written approval of such actions, which approval shall not be unreasonably withheld, conditioned or delayed so long as such actions, in Landlord’s reasonable discretion, would not potentially have any adverse effect on the Property, and, in any event, Landlord shall not withhold its approval of any proposed actions which are required by applicable Environmental Laws. For the avoidance of doubt, the parties acknowledge that Tenant shall not be required to perform remediation to reduce the level of contamination of the Premises, Building, or Property below the levels of contamination which exist as of the Execution Date. The provisions of this Section 17.5 shall survive the expiration or earlier termination of the Lease.

(b) Without limiting the obligations set forth in Section 17.5(a) above, if any Hazardous Material is in, on, under, at or about the Building or the Property as a result of the acts or omissions of any of the Tenant Parties and results in any contamination of any part of the Property or any

adjacent property that is in violation of any applicable Environmental Law or that requires the performance of any response action pursuant to any Environmental Law, Tenant shall promptly take all actions at Tenant’s sole cost and expense as are necessary to reduce such Hazardous Material to amounts below any applicable Reportable Quantity, any applicable Reportable Concentration and any other applicable standard set forth in Environmental Laws such that no further response actions are required; provided that Tenant shall first obtain Landlord’s written approval of such actions, which approval shall not be unreasonably withheld, conditioned or delayed so long as such actions would not be reasonably expected to have an adverse effect on the market value or utility of the Property for the Permitted Uses, and in any event, Landlord shall not withhold its approval of any proposed actions which are required by applicable Environmental Laws (such approved actions, “Tenant’s Remediation”).

(i) provided that Landlord does not permit occupancy of the Premises prior to the completion of Tenant’s Remediation, until the completion of Tenant’s Remediation (as evidenced by the certification of Tenant’s Licensed Site Professional (as such term is defined by applicable Environmental Laws), who shall be reasonably acceptable to Landlord) (the “Remediation Completion Date”), Tenant shall pay to Landlord, with respect to the portion of the Premises which reasonably cannot be occupied by a new tenant until completion of Tenant’s Remediation, (A) Additional Rent on account of Operating Costs and Taxes and (B) Base Rent in an amount equal to the greater of (1) the fair market rental value of such portion of the Premises (determined in substantial accordance with the process described in Section 1.2 above), and (2) Base Rent attributable to such portion of the Premises in effect immediately prior to the end of the Term; and

(ii) Tenant shall maintain responsibility for Tenant’s Remediation and Tenant shall complete Tenant’s Remediation as soon as reasonably practicable in accordance with Environmental Laws. If Tenant does not diligently pursue completion of Tenant’s Remediation, Landlord shall have the right to either (A) assume control for overseeing Tenant’s Remediation, in which event Tenant shall pay all reasonable costs and expenses of Tenant’s Remediation (it being understood and agreed that all costs and expenses of Xxxxxx’s Remediation incurred pursuant to contracts entered into by Tenant shall be deemed reasonable) within thirty (30) days of demand therefor (which demand shall be made no more often than monthly), and Landlord shall be substituted as the party identified on any governmental filings as the party responsible for the performance of such Tenant’s Remediation or (B) require Tenant to maintain responsibility for Tenant’s Remediation, in which event Tenant shall complete Tenant’s Remediation as soon as reasonably practicable in accordance with Environmental Laws, it being understood that Tenant’s Remediation shall not contain any requirement that Tenant remediate any contamination to levels or standards more stringent than those associated with the Property’s current office, research and development, laboratory, and vivarium uses.

(d) The provisions of this Section 17.5 shall survive the expiration or earlier termination of this Lease.

17.6 Disclosures. In connection with bringing any Hazardous Material into any part of the Property, Tenant shall maintain, and upon Landlord’s request, deliver to Landlord (subject to the provisions of Section 26.16) the following information with respect thereto: (a) a description of handling, storage, use and disposal procedures; (b) all life or environmental safety plans or disclosures and/or emergency response plans which Tenant has prepared, including without limitation Tenant’s Spill Response Plan, and all plans which Tenant is required to supply to any governmental agency or authority pursuant to any Environmental Laws; (c) copies of all Required Permits relating thereto; and (d) other information related to life or environmental safety reasonably requested by Landlord.

17.7 Removal. Tenant shall be responsible, at its sole cost and expense, for Hazardous Material and other biohazard disposal services for the Premises. Such services shall be performed by contractors reasonably acceptable to Landlord and on a sufficient basis to ensure that the Premises are at all times kept neat, clean and free of waste, Hazardous Materials and biohazards except in appropriate, specially marked containers reasonably approved by Landlord. Furthermore, if any Legal Requirements require that any substances be disposed of separately from ordinary trash, Tenant shall make arrangements at Tenant’s expense for such disposal directly with a qualified and licensed disposal company reasonably acceptable to Landlord at a lawful disposal site.

17.8 Landlord’s Obligations.

(a) Landlord Representations, Covenants and Indemnity. Landlord hereby represents and warrants to Tenant that, to the Best of Landlord’s Knowledge (as that term is defined in clause (c) below), except to the extent (if any) as may be disclosed in the following described environmental assessment reports which have been made available by Landlord to Tenant (the “Disclosed Materials”), there exist, as of the Execution Date of this Lease, no Hazardous Materials on the Property which are in violation of applicable Environmental Laws or that require reporting, investigation, remediation or other response under Chapter 21E or other Environmental Laws:

(b) Landlord Remediation. If Hazardous Materials are discovered in, on or under the Property which are not in compliance with applicable Environmental Laws or that require reporting, investigation, remediation or other response under Chapter 21E or other Environmental Laws, and which are not the responsibility of Tenant pursuant to this Article 17, then Landlord shall remove or remediate the same, when, if, and in the manner required by applicable Environmental Laws.

(c) To the Best of Xxxxxxxx’s Knowledge. The phrase “to the Best of Landlord’s Knowledge” under shall mean the best of the knowledge of Xxxxx Xxxxxxx, Xxxxxxxx’s asset manager with respect to the Property.

18. RULES AND REGULATIONS.

18.1 Rules and Regulations. Tenant will faithfully observe and comply with all reasonable

rules and regulations promulgated from time to time with respect to the Building, the Property and construction within the Property of which Xxxxxx has prior written notice (collectively, the “Rules and Regulations”). The current version of the Rules and Regulations is attached hereto as Exhibit 8. In the case of any conflict between the provisions of this Lease and any future rules and regulations, the provisions of this Lease shall control. Xxxxxxxx agrees to enforce the Rules and Regulations against all tenants of the Building in a uniform and non-discriminatory manner, but Landlord shall not be liable to Tenant for violation of the same by any other tenant, its servants, employees, agents, contractors, visitors, invitees or licensees.

18.2 Energy Conservation. Landlord may institute upon written notice to Tenant such reasonable conservation and/or preservation of energy or energy services policies, programs and measures:

a. as may be necessary, required, or expedient, in Landlord’s good faith judgment (“Elective Conservation Programs”), provided however, that: (i) no Elective Conservation Program shall reduce the level of energy or energy services (A) being provided to the Premises below the level of energy or energy services then being provided in comparable combination laboratory, research and development, GMP manufacturing, and office buildings in the vicinity of the Premises or (B) required pursuant to terms and conditions of this Lease, and (ii) Tenant shall have no obligation, as the result of an Elective Conservation Program, to incur any additional costs (other than de minimis costs) or alter any of its operations in the Premises in a manner that could adversely affect Tenant’s business to do so; or

b. as may be necessary or required to comply with Legal Requirements (collectively, the “Required Conservation Program”).

Landlord shall consult with Tenant prior to implementing any Conservation Program.

18.3 Recycling. Upon written notice, Landlord may establish policies, programs and measures for the recycling of paper, products, plastic, tin and other materials (a “Recycling Program”). Upon receipt of such notice, Xxxxxx will comply with the Recycling Program at Tenant’s sole cost and expense.

19. LAWS AND PERMITS.

19.1 Legal Requirements. Tenant shall be responsible at its sole cost and expense for complying with (and keeping the Premises in compliance with) all Legal Requirements which are applicable to Tenant’s particular use or occupancy of, as opposed to office and laboratory use generally, or Alterations made by or on behalf of Tenant to, the Premises. Tenant shall furnish all data and information to governmental authorities, with a copy of any non-proprietary information to Landlord, as required in accordance with Legal Requirements as they relate to Tenant’s use or occupancy of the Premises or the Building. If Tenant receives notice of any violation of Legal Requirements applicable to the Premises or the Building, it shall give prompt notice thereof to Landlord (provide that failure to do so shall not be deemed to be a default hereunder). Nothing contained in this Section 19.1 shall be construed to expand the uses permitted hereunder beyond the Permitted Uses. Landlord shall comply with any Legal Requirements and with any direction of any public office or officer relating to the maintenance or operation of the Building as a combination laboratory, research and development and office building, and the costs so incurred by Landlord shall be included in Operating Costs in accordance with, and subject to the limitations set forth in, the provisions of Section 5.2.

19.2 Required Permits. Tenant shall, at Tenant’s sole cost and expense, use diligent good faith efforts to apply for, seek and obtain all necessary state and local licenses, permits and approvals

needed for the operation of Tenant’s business and/or Tenant’s Rooftop Equipment (collectively, the “Required Permits”), as soon as reasonably possible, and in any event shall not undertake any operations or use of Tenant’s Rooftop Equipment unless all applicable Required Permits are in place. Tenant shall thereafter maintain all Required Permits. Tenant, at Tenant’s expense, shall at all times comply with the terms and conditions of each such Required Permit. Landlord shall cooperate with Tenant, at Tenant’s sole cost and expense, in connection with its application for Required Permits.

19.3 Traffic Management. Tenant acknowledges that the Property may become subject to a traffic mitigation and/or management plan (the “PTDM”). Xxxxxx agrees not to violate the terms of the PTDM applicable to tenants of the Building. Tenant shall, at Tenant’s sole expense, for so long as the PTDM remains applicable to the Property, (a) to the extent required by the PTDM, allow employees at the Premises to set-aside pre-tax funds as allowable under the Commuter Choice provision of the Federal tax code, and (b) reasonably cooperate with Landlord in (i) connection with Landlord’s reporting obligations under the PTDM and any amendments thereto, and (ii) to the extent required by the PTDM, encouraging employees to avoid vehicle trips at peak commuting hours and to seek alternate modes of transportation. The costs incurred by Landlord in connection with compliance with the PTDM (and expressly excluding any capital expenditures) shall be included in Operating Costs.

20. DEFAULT

20.1 Events of Default. The occurrence of any one or more of the following events shall constitute an “Event of Default” hereunder by Xxxxxx:

(a) If Tenant fails to make any payment of Rent or any other payment required hereunder, as and when due, and such failure shall continue for a period of five (5) days after notice thereof from Landlord to Tenant; provided, however, an Event of Default shall occur hereunder without any obligation of Landlord to give any notice if (i) Tenant fails to make any payment within five (5) days after the due date therefor, and (ii) Landlord has given Tenant written notice under this Section 20.1(a) on more than one (1) occasion during the twelve (12) month interval preceding such failure by Xxxxxx;

(b) If Tenant shall fail to execute and deliver to Landlord an estoppel certificate pursuant to Section 16 above or a subordination and attornment agreement pursuant to Section 22 below, within the timeframes set forth therein, following notice and an additional five (5) day period in which to cure such failure;

(e) If Tenant shall fail to restore the Security Deposit to its original amount or deliver a replacement Letter of Credit as required under Section 7 above;

(f) If Tenant shall make a Transfer in violation of the provisions of Section 13 above, or if any event shall occur or any contingency shall arise whereby this Lease, or the Term and estate thereby created, would (by operation of law or otherwise) devolve upon or pass to any person, firm or corporation other than Tenant, except as expressly permitted under Section 13 hereof, and Tenant does not cure such default with ten (10) days following notice from Landlord;

(g) The failure by Tenant to observe or perform any of the covenants or provisions of this Lease to be observed or performed by Tenant, other than as specified above, and such failure continues for more than thirty (30) days after notice thereof from Landlord; provided, further, that if the nature of Tenant’s default is such that more than thirty (30) days are reasonably required for its cure, then Tenant shall not be deemed to be in default if Tenant shall commence such cure within said thirty (30) day period and thereafter diligently prosecute such cure to completion;

(h) If Tenant shall make an admission in writing of Tenant’s inability to pay its debts generally as they become due;

(i) If Tenant shall make an assignment or trust mortgage, or other conveyance or transfer of like nature, of all or a substantial part of its property for the benefit of its creditors,

(j) If an attachment on mesne process, on execution or otherwise, or other legal process shall issue against Tenant or a material property of Tenant and a sale of any of its assets shall be held thereunder;

(k) If the leasehold hereby created shall be taken on execution or by other process of law and shall not be revested in Tenant within sixty (60) days thereafter;

(l) If a receiver, sequesterer, trustee or similar officer shall be appointed by a court of competent jurisdiction to take charge of all or any part of Tenant’s Property and such appointment shall not be vacated within sixty (60) days; or

(m) If any proceeding shall be instituted by or against Tenant pursuant to any of the provisions of any Act of Congress or State law relating to bankruptcy, reorganizations, arrangements, compositions or other relief from creditors, and, in the case of any proceeding instituted against it, if Tenant shall fail to have such proceedings dismissed within sixty (60) days or if Tenant is adjudged bankrupt or insolvent as a result of any such proceeding.

Wherever “Tenant” is used in subsections (h), (i), (j), (l) or (m) of this Section 20.1, it shall be deemed to include any guarantor of any of Tenant’s obligations under this Lease.

20.2 Remedies. Upon an Event of Default, Landlord may, by notice to Tenant, elect to terminate this Lease; and thereupon (and without prejudice to any remedies which might otherwise be available for arrears of Rent or preceding breach of covenant or agreement and without prejudice to Tenant’s liability for damages as hereinafter stated), upon the giving of such notice, this Lease shall terminate as of the date specified therein as though that were the Expiration Date. Upon such termination, Landlord shall have the right to utilize the Security Deposit or draw down the entire Letter of Credit, as applicable, and apply the proceeds thereof to its damages hereunder. Without being taken or deemed to be guilty of any manner of trespass or conversion, and without being liable to indictment, prosecution or damages therefor, Landlord may, by lawful process, enter into and upon the Premises (or any part thereof in the name of the whole); repossess the same, as of its former estate; and expel Tenant and those claiming under Xxxxxx. The words “re-entry” and “re-enter” as used in this Lease are not restricted to their technical legal meanings.

20.3 Damages - Termination.

(a) Upon the termination of this Lease under the provisions of this Section 20, Tenant shall pay to Landlord Rent up to the time of such termination, shall continue to be liable for any preceding breach of covenant, and in addition, shall pay to Landlord as damages, at the election of Landlord, either:

(i) the amount (discounted to present value at the rate of eight percent (8%) per annum) by which, at the time of the termination of this Lease (or at any time thereafter if Landlord shall have initially elected damages under Section 20.3(a)(ii) below), (x) the aggregate of Rent projected over the period commencing with such termination and ending on the Expiration Date, exceeds (y) the aggregate projected rental value of the Premises for such period, taking into account a reasonable time period during which the Premises shall be unoccupied, plus all Reletting Costs (hereinafter defined); or

(ii) amounts equal to Rent which would have been payable by Tenant had this Lease not been so terminated, payable upon the due dates therefor specified herein following such termination and until the Expiration Date, provided, however, if Landlord shall re-let the Premises during such period, that Landlord shall credit Tenant with the net rents received by Landlord from such re-letting, such net rents to be determined by first deducting from the gross rents as and when received by Landlord from such re-letting the expenses incurred or paid by Landlord in terminating this Lease, as well as the expenses of re-letting, including altering and preparing the Premises for new tenants, brokers’ commissions, and all other similar and dissimilar expenses properly chargeable against the Premises and the rental therefrom (collectively, “Reletting Costs”), it being understood that any such re-letting may be for a period equal to or shorter or longer than the remaining Term; and provided, further, that (x) in no event shall Tenant be entitled to receive any excess of such net rents over the sums payable by Tenant to Landlord hereunder and (y) in no event shall Tenant be entitled in any suit for the collection of damages pursuant to this Section 20.3(a)(ii) to a credit in respect of any net rents from a re-letting except to the extent that such net rents are actually received by Landlord prior to the commencement of such suit. If the Premises or any part thereof should be re-let in combination with other space, then proper apportionment on a square foot area basis shall be made of the rent received from such re-letting and of the expenses of re-letting.

(b) In calculating the amount due under Section 20.3(a)(i), above, there shall be included, in addition to the Base Rent, all other considerations agreed to be paid or performed by Xxxxxx, including without limitation Tenant’s Share of Operating Costs and Taxes, on the assumption that all such amounts and considerations would have increased at the rate of five percent (5%) per annum for the balance of the full term hereby granted.

(c) Suit or suits for the recovery of such damages, or any installments thereof, may be brought by Landlord from time to time at its election, and nothing contained herein shall be deemed to require Landlord to postpone suit until the date when the Term would have expired if it had not been terminated hereunder.

(d) Nothing herein contained shall be construed as limiting or precluding the recovery by Landlord against Tenant of any sums or damages to which, in addition to the damages particularly provided above, Landlord may lawfully be entitled by reason of any Event of Default hereunder. After a termination of this Lease pursuant to this Section 20, Landlord will use reasonable efforts to relet the Premises after Tenant vacates the Premises; however, the marketing of the Premises in a manner similar to the manner in which Landlord markets other premises in the Building shall be deemed to have satisfied Landlord’s obligation to use “reasonable efforts.” In no event shall Landlord be required to (i) solicit or entertain negotiations with any other prospective tenants for the Premises unless and until Landlord obtains full and complete possession of the Premises, including the final and unappealable legal right to relet the Premises free of any claim of Tenant, (ii) lease the Premises to a tenant whose proposed use, in Landlord’s reasonable judgment, will be unacceptable, (iii) relet the Premises prior to leasing any other vacant space in the Building, suitable for the use of the prospective tenant, (iv) lease the Premises for a rental rate less than the current fair market rent then prevailing for similar space in the Building, or (v) enter into a lease with any proposed tenant that does not have, in Landlord’s reasonable opinion, sufficient financial wherewithal and resources to satisfy its financial obligations under the prospective lease. Landlord shall be entitled to take into account in connection with any such reletting of the Premises all relevant factors which would be taken into account by a sophisticated landlord in securing a replacement tenant for the Premises including the first class quality of the Property, and the financial responsibility of any such replacement tenant.

(e) In lieu of any other damages or indemnity and in lieu of full recovery by Landlord of all sums payable under all the foregoing provisions of this Section 20.3, Landlord may, by written notice to Tenant, at any time after this Lease is terminated under any of the provisions herein contained or is otherwise terminated for breach of any obligation of Tenant and before such full recovery,

elect to recover, and Tenant shall thereupon pay, as liquidated damages, an amount equal to the aggregate of (x) an amount equal to the lesser of (1) Rent accrued under this Lease in the twelve (12) months immediately prior to such termination, or (2) Rent payable during the remaining months of the Term if this Lease had not been terminated, plus (y) the amount of Rent accrued and unpaid at the time of termination, less (z) the amount of any recovery by Landlord under the foregoing provisions of this Section 20.3 up to the time of payment of such liquidated damages.

20.4 Landlord’s Self-Help. If Tenant shall default in the performance of any covenant on Tenant’s part to be performed in this Lease contained, including without limitation the obligation to maintain the Premises in the required condition pursuant to Section 10.1 above, Landlord may, after the expiration of the cure periods set forth in Section 20.1 above and upon reasonable advance notice (except that in an emergency or if any such default constitutes a violation of Legal Requirements no notice shall be required and Landlord shall not be required to wait for the expiration of such cure periods), immediately, or at any time thereafter, perform the same for the account of Xxxxxx. Tenant shall pay to Landlord upon demand therefor any reasonable costs incurred by Landlord in connection therewith, together with interest at the Default Rate until paid in full.

20.5 Waiver of Redemption, Statutory Notice and Grace Periods. Tenant does hereby waive and surrender all rights and privileges which it might have under or by reason of any present or future Legal Requirements to redeem the Premises or to have a continuance of this Lease for the Term hereby demised after being dispossessed or ejected therefrom by process of law or under the terms of this Lease or after the termination of this Lease as herein provided. Except to the extent prohibited by Legal Requirements, any statutory notice and grace periods provided to Tenant by law are hereby expressly waived by Tenant.

20.6 Landlord’s Remedies Not Exclusive. The specified remedies to which Landlord may resort hereunder are cumulative and are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be lawfully entitled, and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were not herein provided for.

20.7 No Waiver. Either party’s failure to seek redress for violation, or to insist upon the strict performance, of any covenant or condition of this Lease, or any of the Rules and Regulations promulgated hereunder, shall not prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by Landlord of Rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach. The failure of Landlord to enforce any of such Rules and Regulations against Tenant and/or any other tenant in the Building shall not be deemed a waiver of any such Rules and Regulations. No provisions of this Lease shall be deemed to have been waived by either party unless such waiver be in writing signed by such party. No payment by Tenant or receipt by Landlord of a lesser amount than the Rent herein stipulated shall be deemed to be other than on account of the stipulated Rent, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other remedy in this Lease provided.

20.8 Restrictions on Tenant’s Rights. During the continuation of any monetary or material non-monetary Event of Default, (a) Landlord shall not be obligated to provide Tenant with any notice pursuant to Sections 2.3 and 2.4 above; and (b) Tenant shall not have the right to make, nor to request Xxxxxxxx’s consent or approval with respect to, any Alterations or Transfers.

20.9 Landlord Default.

(a) Notwithstanding anything to the contrary contained in the Lease, Landlord shall

in no event be in default in the performance of any of Landlord’s obligations under this Lease unless Landlord shall have failed to perform such obligations within thirty (30) days (or such additional time as is reasonably required to correct any such default, provided Landlord commences cure within thirty (30) days and thereafter diligently prosecute such cure to completion) after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation. Except as expressly set forth in this Lease, Tenant shall not have the right to terminate or cancel this Lease or to withhold rent or to set-off or deduct any claim for damages against rent as a result of any default by Landlord or breach by Landlord of its covenants or any warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the Premises (constructive or actual) by Landlord, unless same continues after notice to Landlord thereof and an opportunity for Landlord to cure the same as set forth above. In addition, other than as set forth in Section 9.6(b). Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against Landlord from rent thereafter due and payable under this Lease except as expressly set forth in Section 20.9(b) below.

(b) If Landlord is in default (determined in accordance with Section 20.9(a) above) under any provision of this Lease other than Section 3 hereof (it being understood and agreed that Xxxxxx’s remedies for Landlord’s default of Landlord’s Section 3 obligations are set forth in said Section 3), or if Landlord’s failure to perform any of its obligations hereunder poses an imminent risk of damage or injury to persons or property or constitutes a violation of Legal Requirements and if such default or failure, as the case may be, materially adversely affects Tenant’s ability to operate its business in the ordinary course in accordance with the terms of this Lease, then Tenant shall have the right to cure such default or perform such obligation which Landlord failed to perform, as the case may be, on Landlord’s behalf (provided that Tenant shall not violate or render void any warranties maintained by Landlord of which Tenant has prior written notice, and in no event shall any such cure affect any other tenant in the Building), in which event Landlord shall reimburse Tenant within thirty (30) days after receipt of a reasonably detailed invoice for all reasonable costs and expenses incurred by Xxxxxx in connection therewith, together with interest at the Default Rate. Tenant’s self-help rights under this Section 20.9(b) shall be exercised by Tenant only (i) with respect to conditions that materially adversely affect Tenant’s ability to operate its business in the ordinary course in accordance with the terms of this Lease, and (ii) except in the event of an emergency or a violation of Legal Requirements (in either of which events Tenant shall provide notice to Landlord’s designated emergency contact, which notice may be by e-mail or oral, which contact information shall be provided in writing to Tenant and may be changed by Landlord by written notice from time to time), after Xxxxxx has provided Landlord with notice of Tenant’s intention to exercise such right (which notice shall be delivered in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE SELF-HELP” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to this Section 20.9 and Landlord’s failure to perform the specified obligation will trigger the provisions of this Section 20.9, and which notice shall include a copy of the default notice delivered pursuant to Section 20.9(a) above), and Landlord has failed to commence action to remedy the condition complained of within ten (10) days after its receipt of such notice (or if Landlord commences to do the act required within such ten (10) day period but fails to proceed diligently thereafter). The provisions of this Section 20.9(b) are personal to Replimune Group, Inc. and its Successor(s). If Landlord fails to reimburse Tenant for Xxxxxx’s costs incurred pursuant to this Section 20.9(b) within the aforementioned 30 day period, then Tenant may send Landlord a notice in an envelope that conspicuously states the following in bold caps: “TENANT NOTICE OF INTENTION TO EXERCISE OFF-SET” and which notice shall include an explicit statement that such notice is a notice delivered pursuant to this Section 20.9(b) and describing Xxxxxxxx’s failure to make such reimbursement and, if Xxxxxxxx fails to reimburse Tenant within ten (10) days following delivery of such notice, then Tenant may off-set such amounts, together with interest at the Default Rate from the date incurred by Xxxxxx, against the Rent due hereunder until Xxxxxx is paid in full (provided that such off-set shall not exceed 15% of the Base Rent due from Tenant in any one month).

21. SURRENDER; ABANDONED PROPERTY; HOLD-OVER

21.1 Surrender.

(a) Upon the expiration or earlier termination of the Term, Tenant shall (i) peaceably quit and surrender to Landlord the Premises (including without limitation all fixed lab benches, fume hoods, electric, plumbing, heating and sprinkling systems, fixtures and outlets, vaults, paneling, molding, shelving, radiator enclosures, cork, rubber, linoleum and composition floors, ventilating, silencing, air conditioning and cooling equipment therein) broom clean in the condition in which Tenant was obligated to maintain the same, excepting only ordinary wear and tear and damage by fire or other Casualty; (ii) remove all of Tenant’s Property, all autoclaves and cage washers and, to the extent specified by Landlord in accordance with Section 11.1 above, Alterations made by Tenant; and (iii) repair any damages to the Premises or the Building caused by the installation or removal of Tenant’s Property and/or such Alterations. Tenant’s obligations under this Section 21.1(a) shall survive the expiration or earlier termination of this Lease.

(b) Prior to the expiration of this Lease (or within thirty (30) days after any earlier termination), Tenant shall clean and otherwise decommission all interior surfaces (including floors, walls, ceilings, and counters), piping, supply lines, waste lines, acid neutralization systems and plumbing in and/or exclusively serving the Premises, and all exhaust or other ductwork in and/or exclusively serving the Premises, in each case which has carried or released or been contacted by any Hazardous Materials or other chemical or biological materials used in the operation of the Premises, and shall otherwise clean the Premises so as to permit the Surrender Plan (defined below) to be issued. At least thirty (30) days prior to the expiration of the Term (or, if applicable, within five (5) business days after any earlier termination of this Lease), Tenant shall deliver to Landlord a reasonably detailed narrative description of the actions proposed (or required by any Legal Requirements) to be taken by Tenant in order to render the Premises (including any Alterations permitted or required by Landlord to remain therein) free of Hazardous Materials introduced by Tenant or any other Tenant Party to the Premises, the Building or the Property (“Tenant HM”), so that the use and occupancy of the Property is not restricted in any way as the result of any Tenant HM, including without limitation, to the extent applicable, causing the Premises to be decommissioned in accordance with the regulations of the U.S. Nuclear Regulatory Commission and/or the Massachusetts Department of Public health (the “MDPH”) for the control of radiation, and cause the Premises to be released for unrestricted use by the Radiation Control Program of the MDPH (the “Surrender Plan”). For avoidance of doubt, however, the parties acknowledge that Tenant shall not be required to perform remediation to reduce the level of contamination of the Premises, Building, or Property below the levels of contamination which exist as of the Execution Date. The Surrender Plan (i) shall be accompanied by a current list of (A) all Required Permits held by or on behalf of any Tenant Party with respect to Hazardous Materials in, on, under, at or about the Premises, and (B) Tenant’s Hazardous Materials, and (ii) shall be subject to the reasonable review and approval of Landlord’s environmental consultant. In connection with review and approval of the Surrender Plan, upon request of Landlord, Tenant shall deliver to Landlord or its consultant such additional non-proprietary information concerning the use of and operations within the Premises as Landlord shall reasonably request. On or before the expiration of the Term (or within thirty (30) days after any earlier termination of this Lease, during which period Tenant’s use and occupancy of the Premises shall be governed by Section 21.3 below), Tenant shall deliver to Landlord a certification from a qualified third-party environmental professional reasonably approved by Landlord or from an industrial hygienist reasonably acceptable to Landlord certifying that the portions of the Premises subject to decommissioning under the Surrender Plan do not contain any Tenant HM and evidence that the approved Surrender Plan shall have been satisfactorily completed by a contractor reasonably acceptable to Landlord, and Landlord shall have the right, subject to reimbursement at Tenant’s expense as set forth below if Tenant is not in compliance with the terms of this subparagraph, to cause Landlord’s environmental consultant to inspect the Premises and perform such additional procedures as may be deemed reasonably necessary to confirm that the Premises are, as of the expiration of the Term (or, if applicable, the date which is thirty (30) days after any earlier termination of this Lease), free of Hazardous Materials to the extent set forth above and otherwise

available for unrestricted use and occupancy for the Permitted Uses. Landlord shall have the unrestricted right to deliver the Surrender Plan and any report by Xxxxxxxx’s environmental consultant with respect to the surrender of the Premises to third parties; however, only Landlord Parties and Landlord’s lender(s) shall be entitled to rely on the Surrender Report. If Tenant shall fail to prepare or submit a Surrender Plan approved by Landlord, or if Tenant shall fail to complete the approved Surrender Plan, or if such Surrender Plan, whether or not approved by Landlord, shall fail to adequately address the use of Hazardous Materials by any of the Tenant Parties in, on, at, under or about the Premises, (A) Landlord shall have the right to take any such actions as Landlord may deem reasonable or appropriate to assure that the Premises and the Property are surrendered in the condition required hereunder, the reasonable third-party cost of which actions shall be reimbursed by Xxxxxx as Additional Rent upon demand; and (B) if the Term shall have ended, unless and until Landlord elects to take such actions to assure that the Premises are surrendered in the condition required hereunder, Tenant shall be deemed to be a holdover tenant subject to the provisions of Section 21.3 below until the earlier to occur of the date on which (i) Tenant delivers the Surrender Report (in the form required hereunder) to Landlord, or (ii) Landlord or any other third party takes occupancy of the Premises or otherwise enters the Premises to commence demolition or other work. Tenant’s obligations under this Section 21.1(b) shall survive the expiration or earlier termination of the Term.

(c) No act or thing done by Landlord during the Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid, unless in writing signed by Xxxxxxxx. Unless otherwise agreed by the parties in writing, no employee of Landlord or of Landlord’s agents shall have any power to accept the keys of the Premises prior to the expiration or earlier termination of this Lease. The delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of this Lease or a surrender of the Premises.

(d) Notwithstanding anything to the contrary contained herein, Tenant shall, at its sole cost and expense, remove from the Premises, prior to the end of the Term, any item installed by or for Tenant that has been exposed to Hazardous Materials, and which, pursuant to Legal Requirements, must be removed therefrom on account of such exposure before the Premises may be used by a subsequent tenant.

21.2 Abandoned Property. After the expiration or earlier termination hereof, if Tenant fails to remove any property from the Building or the Premises which Tenant is obligated by the terms of this Lease to remove within five (5) business days after written notice from Landlord, such property (the “Abandoned Property”) shall be conclusively deemed to have been abandoned, and may either be retained by Landlord as its property or sold or otherwise disposed of in such manner as Landlord may see fit. If any item of Abandoned Property shall be sold, Tenant hereby agrees that Landlord may receive and retain the proceeds of such sale and apply the same, at its option, to the expenses of the sale, the cost of moving and storage, any damages to which Landlord may be entitled under Section 20 hereof or pursuant to law, and to any arrears of Rent.

21.3 Holdover. If any of the Tenant Parties holds over after the end of the Term, Tenant shall be deemed a tenant-at-sufferance subject to the provisions of this Lease; provided that whether or not Landlord has previously accepted payments of Rent from Tenant, (i) Tenant shall pay Base Rent at 150% of the last applicable rate of Base Rent for the first thirty (30) days of such holdover and thereafter 200% of the last applicable rate of Base Rent payable during the Term, which such Base Rent shall be prorated on a per diem basis for partial months, (ii) Tenant shall continue to pay to Landlord all Additional Rent, and (iii) if such holdover continues for more than thirty (30) days, Tenant shall be liable for all actual damages, including without limitation lost business and consequential damages, incurred by Landlord as a result of such holding over, Tenant hereby acknowledging that Landlord may need the Premises after the end of the Term for other tenants and that the damages which Landlord may suffer as the result of Xxxxxx’s holding over cannot be determined as of the Execution Date. Nothing contained herein shall

grant Tenant the right to holdover after the expiration or earlier termination of the Term.

22. MORTGAGEE RIGHTS

22.1 Subordination. Tenant’s rights and interests under this Lease shall be (i) subject and subordinate to any ground lease, overleases, mortgage, deed of trust, or similar instrument covering the Premises, the Building and/or the Land and to all advances, modifications, renewals, replacements, and extensions thereof (each of the foregoing, a “Mortgage”) so long as the applicable Mortgagee and Tenant execute a commercially reasonable subordination, non-disturbance and attornment agreement (“SNDA”) (the form of SNDA attached as Exhibit 12 being deemed commercially reasonable, subject to appropriate revisions following the completion of the Landlord’s Work and funding of Landlord’s Contribution), or (ii) if any Mortgagee elects, prior to the lien of any present or future Mortgage. Tenant further shall attorn to and recognize any successor landlord, whether through foreclosure or otherwise, as if the successor landlord were the originally named landlord. Xxxxxx agrees to execute, acknowledge and deliver such instruments, confirming such subordination and attornment, within fifteen (15) days of request therefor. Simultaneously with the execution and delivery of this Lease, Landlord, Tenant, and Landlord’s current Mortgagee shall enter into an SNDA in the form attached as Exhibit 12.

22.2 Notices. Subject to the terms of any SNDA, Tenant shall give each Mortgagee of which Tenant has been provided prior written notice the same notices given to Landlord concurrently with the notice to Landlord, and each Mortgagee shall have a reasonable opportunity thereafter concurrent with Landlord’s cure period but including such additional time required to take possession of the Premises if such possession is reasonably necessary to cure such default, but not to exceed 180 days in the aggregate) to cure a Landlord default, and Mortgagee’s curing of any of Landlord’s default shall be treated as performance by Landlord.

22.3 Intentionally Omitted.

22.4 Mortgagee Liability. Subject to the terms of any SNDA, Tenant acknowledges and agrees that if any Mortgage shall be foreclosed, (a) the liability of the Mortgagee and its successors and assigns shall exist only so long as such Mortgagee or purchaser is the owner of the Premises, and such liability shall not continue or survive after further transfer of ownership; and (b) such Mortgagee and its successors or assigns shall not be (i) liable for any act or omission of any prior lessor under this Lease; (ii) liable for the performance of Landlord’s covenants pursuant to the provisions of this Lease which arise and accrue prior to such entity succeeding to the interest of Landlord under this Lease or acquiring such right to possession; (iii) subject to any offsets or defense which Tenant may have at any time against Landlord (other than Tenant’s express rights under Sections 3.2, 3.4(d), 9.5(b) and 20.9(b) of this Lease); (iv) bound by any base rent or other sum which Tenant may have paid previously for more than one (1) month; or (v) liable for the performance of any covenant of Landlord under this Lease which is capable of performance only by the original Landlord, provided that in no event shall the foregoing clauses (i)-(iii) or (v) relieve any such Mortgagee and its successors and assigns from ongoing Landlord’s obligations to provide maintenance, repair or any other on-going Landlord’s Services (defined in Section 9.6 and listed in Exhibit 6 of this Lease) following the date of such succession.

23. QUIET ENJOYMENT. Landlord covenants that so long as Tenant keeps and performs each and every covenant, agreement, term, provision and condition herein contained on the part and on behalf of Tenant to be kept and performed, subject to applicable notice and cure periods, Tenant shall peaceably and quietly hold, occupy and enjoy the Premises during the Term from and against the claims of all persons lawfully claiming by, through or under Landlord subject, nevertheless, to the covenants, agreements, terms, provisions and conditions of this Lease, and any matters of record set forth on Exhibit 11.

24. NOTICES. Any notice, consent, request, bill, demand or statement hereunder (each, a “Notice”) by either party to the other party shall be in writing and shall be deemed to have been duly given when either delivered by hand or by nationally recognized overnight courier (in either case with evidence of delivery or refusal thereof) addressed as follows:

26.4 Entire Agreement. This Lease, Lease Summary Sheet and Exhibits 1 — 15 attached hereto and incorporated herein contain the entire and only agreement between the parties and any and all statements and representations, written and oral, including previous correspondence and agreements between the parties hereto, are merged herein.

Tenant acknowledges that all representations and statements upon which it relied in executing this Lease are contained herein and that Tenant in no way relied upon any other statements or representations, written or oral.

26.7 Expenses Incurred by Landlord Upon Tenant Requests. Tenant shall, upon demand, reimburse Landlord for all reasonable third party expenses, including, without limitation, legal fees, incurred by Landlord in connection with the review and approval of Xxxxxx’s plans and specifications in connection with proposed Alterations to be made by Tenant to the Premises or in connection with requests by Tenant for Landlord’s consent to make a Transfer or in connection with a request for a Landlord waiver pursuant to Section 8. Such costs shall be deemed to be Additional Rent under this Lease. Notwithstanding the foregoing, Tenant shall not be obligated to reimburse Landlord for third party expenses incurred in connection with the review and approval of Xxxxxx’s plans and specifications for Tenant’s Work and charged to Landlord by Xxxxxxxx’s architect and/or engineers to the extent Tenant engages the same architect and/or engineers.

26.8 Incentives. Landlord shall reasonably cooperate with Tenant at no material cost and expense to Landlord in making application for forms of state and municipal financial assistance with respect to Xxxxxx’s relocation to the Building. To the extent Tenant provides Landlord with reasonable evidence that any such state or municipal financial assistance, including without limitation TIFA, is attributable to Tenant’s occupancy of the Premises, then the whole of any economic benefit therefrom shall inure solely to Tenant.

26.9 Survival. Without limiting any other obligation of the parties which may survive the expiration or prior termination of the Term, all obligations on the part of Landlord or Tenant to indemnify, defend, or hold the other harmless, as set forth in this Lease shall survive the expiration or prior termination of the Term for three (3) years (or such other period as may be expressly set forth herein).

26.10 Limitation of Liability.

This Section 26.10 shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord. Landlord and Xxxxxx specifically agree that in no event shall any officer, director, trustee, employee or representative of Landlord or Tenant or any of the other Landlord Parties or any of the other Tenant Parties ever be personally liable for any obligation under this Lease, nor shall

26.11 Binding Effect. The covenants, agreements, terms, provisions and conditions of this Lease shall bind and benefit the successors and assigns of the parties hereto with the same effect as if mentioned in each instance where a party hereto is named or referred to, except that no violation of the provisions of Section 13 hereof shall operate to vest any rights in any successor or assignee of Tenant.

Upon any sale, transfer or other disposition of the Building, Landlord shall be entirely freed and relieved from the performance and observance thereafter of all covenants and obligations hereunder on the part of Landlord to be performed and observed to the extent that such covenants and obligations are assumed by Xxxxxxxx’s successor, it being understood and agreed in such event (and it shall be deemed and construed as a covenant running with the land) that the person succeeding to Landlord’s ownership of said reversionary interest shall thereupon and thereafter assume, and perform and observe, any and all of such covenants and obligations of Landlord.

26.13 No Grant of Interest. Notwithstanding anything to the contrary contained herein, Tenant shall not grant any interest whatsoever in any fixtures within the Premises or any item paid in whole or in part by Landlord’s Contribution or by Landlord.

26.14 Prevailing Party. If any party to this Agreement shall institute an action to enforce the terms hereof, the prevailing party shall be entitled to reasonable attorneys’ fees and costs from the party determined to have breached the terms of this Agreement. An award of reasonable attorneys’ fees and costs shall be determined by the court. The “prevailing party” shall be the party that obtains final judgment in its favor. If the institution of an action to enforce the terms of this contract is resolved by settlement, the parties will determine what portion, if any, of the injured party’s legal fees and costs will be paid by the breaching party.

26.15 Force Majeure. Neither Landlord nor Tenant shall in any event be liable for failure to perform any of its obligations under this Lease when prevented from doing so by causes beyond its reasonable control, including, without limitation, labor disputes affecting the area generally, breakdown, accident, order or regulation of or by any governmental authority, or failure of supply, or inability by the exercise of reasonable diligence to obtain supplies, parts, or employees necessary to furnish services required under this Lease, or because of war or other emergency, (each, an event of “Force Majeure”); provided, however, in no event shall any such cause limit, affect, delay, detract from, or xxxxx the obligations of either party to make any payments required under this Lease on a timely basis in accordance with the terms and conditions hereof.

26.16 Confidentiality.

(a) In connection with this Lease, from time to time Tenant has delivered and/or will deliver to Landlord, and the Landlord Parties may observe or have the opportunity to review, certain information about Tenant and/or its affiliates, including but not limited to financial information and other information related to the business operations of Tenant and/or its affiliates (such information whether furnished, observed, or reviewed before or after the Execution Date, whether oral, written, or visual, and regardless of the manner in which it is furnished, observed or reviewed, is collectively hereinafter referred to as “Tenant’s Proprietary Information”). Tenant’s Proprietary Information does not include, however, information which (1) is or becomes generally available to the public other than as a result of a disclosure in violation of this Section 26.16 by Landlord or Landlord’s Engaged Persons (as defined below); (2) was available to Landlord on a non-confidential basis prior to its disclosure by Tenant; or (3) becomes available to Landlord on a non-confidential basis from a person other than Tenant who is not to the knowledge of Landlord or Landlord’s Engaged Persons otherwise bound by a confidentiality

agreement with Tenant, or is otherwise not under an obligation to Tenant not to transmit the information to Landlord.

(i) Subject to the provisions of this Section 26.16(a), Landlord hereby covenants and agrees (A) to keep all Tenant’s Proprietary Information confidential; (B) not to disclose or reveal any Tenant’s Proprietary Information to any person other than those persons, including without limitation its and its affiliates’ employees, investors, lenders, agents and representatives, whose duties and responsibilities reasonably require that Tenant’s Proprietary Information be disclosed to them in connection with the ownership, financing, and/or sale of any of Landlord’s interest in and to the Property or any portion thereof including the Premises (such persons are hereinafter referred to as “Landlord’s Engaged Persons”); (C) to cause Landlord’s Engaged Persons to observe the terms of this Section 26.16; and (D) not to use any Tenant’s Proprietary Information for any purpose other than in connection with the ownership, financing, and/or sale of any of Landlord’s interest in and to the Property or any portion thereof including the Premises.

(ii) Notwithstanding the anything to the contrary in this Section 26.16 contained, nothing herein shall preclude Landlord from disclosing Tenant’s Proprietary Information if: (x) required by Legal Requirements, order of governmental authority, or court order, provided that Landlord first notifies Tenant and, to the extent permissible pursuant to applicable Legal Requirements, Tenant is given the reasonable opportunity to seek applicable protections from the recipient (whether by redaction or otherwise) regarding the materials being submitted, so long as any delay resulting from such efforts to Tenant does not result in any liability to Landlord or (y) in any litigation or other dispute resolution proceeding between the parties hereto to the extent that the inability to disclose Tenant’s Proprietary Information in such proceeding will be prejudicial to Landlord’s rights. In the event that Landlord is requested pursuant to, or required by, applicable law or regulation or by legal process to disclose any Tenant’s Proprietary Information, Landlord agrees that it will provide Tenant with reasonable notice, in the circumstances, of such request or requirement in order to enable Tenant to seek an appropriate protective order or other remedy, to resist or narrow the scope of such request or legal process, or to waive compliance, in whole or in part, with the terms of this Section 26.16. In any such event Landlord will use reasonable efforts under the circumstances in which disclosure is sought to ensure that all Tenant’s Proprietary Information will be accorded confidential treatment by the entity compelling such disclosure and Tenant shall respond in such a time and manner that does not put Landlord or any of its Engaged Persons at risk of violation of such law or regulation or legal process.

(iii) Without prejudice to the rights and remedies otherwise available at law or in equity, Landlord agrees that Tenant shall be entitled to seek equitable relief by way of injunction or otherwise if Landlord or any of Landlord’s Engaged Persons breach or threaten to breach any of the provisions of this Section 26.16.

(b) In connection with this Lease, from time to time Landlord has delivered and/or will deliver to Tenant certain information about the Property, which may include, without limitation, title, zoning, geotechnical, permitting, environmental and operational materials relating to the Property (such information whether furnished, observed, or reviewed before or after the Execution Date, whether oral, written, or visual, and regardless of the manner in which it is furnished, observed or reviewed, is collectively hereinafter referred to as “Landlord’s Proprietary Information”). Xxxxxxxx’s Proprietary Information does not include, however, information which (1) is or becomes generally available to the public other than as a result of a disclosure in violation of this Section 26.16 by Tenant or Tenant’s Engaged Persons (as defined below); (2) was available to Tenant on a non-confidential basis prior to its disclosure by Landlord; or (3) becomes available to Tenant on a non-confidential basis from a person other than Landlord who is not to the knowledge of Tenant or Xxxxxx’s Engaged Persons otherwise bound

by a confidentiality agreement with Landlord, or is otherwise not under an obligation to Landlord not to transmit the information to Tenant.

(i) Subject to the provisions of this Section 26.16(b), Tenant hereby covenants and agrees (A) to keep all Landlord’s Proprietary Information confidential; (B) not to disclose or reveal any Landlord’s Proprietary Information to any person other than those persons, including without limitation its and its affiliates’ employees, investors, lenders, agents and representatives, whose duties and responsibilities reasonably require that Landlord’s Proprietary Information be disclosed to them in connection with this Lease (such persons are hereinafter referred to as “Tenant’s Engaged Persons”); (C) to cause Tenant’s Engaged Persons to observe the terms of this Section 26.16; and (D) not to use any Landlord’s Proprietary Information for any purpose other than in connection with this Lease.

(ii) Notwithstanding the anything to the contrary in this Section 26.16 contained, nothing herein shall preclude Tenant from disclosing Landlord’s Proprietary Information if: (x) required by Legal Requirements, order of governmental authority, or court order, or (y) in any litigation or other dispute resolution proceeding between the parties hereto. In the event that Tenant is requested pursuant to, or required by, applicable law or regulation or by legal process to disclose any Landlord’s Proprietary Information, Tenant agrees that it will provide Landlord with reasonable notice of such request or requirement in order to enable Landlord to seek an appropriate protective order or other remedy, to resist or narrow the scope of such request or legal process, or to waive compliance, in whole or in part, with the terms of this Section 26.16. In any such event Tenant will use reasonable efforts under the circumstances in which disclosure is sought to ensure that all Landlord’s Proprietary Information will be accorded confidential treatment by the entity compelling such disclosure and Landlord shall respond in such a time and manner that does not put Tenant or any of its Engaged Persons at risk of violation of such law or regulation or legal process.

(iii) Without prejudice to the rights and remedies otherwise available at law or in equity, Xxxxxx agrees that Landlord shall be entitled to seek equitable relief by way of injunction or otherwise if Tenant or any of Tenant’s Engaged Persons breach or threaten to breach any of the provisions of this Section 26.16.

(c) Landlord will be responsible for any breach of the terms of this Section 26.16 by it and/or Landlord’s Engaged Persons. Tenant will be responsible for any breach of the terms of this Section 26.16 by it and/or Xxxxxx’s Engaged Persons.

(d) The obligations of the parties under this Section 26.16 shall survive the expiration or prior termination of the Term for three (3) years.

26.17 Financial Information. Unless Tenant is traded on a U.S. public stock exchange, Tenant shall deliver to Landlord, within thirty (30) days after Landlord’s reasonable request (which request may be made no more than two (2) times per year, provided that such limitation shall not apply in the event of a sale or financing of any of Landlord’s interest in the Lease or the property of which the Premises are a part, or if there is an Event of Default by Tenant under this Lease), (a) Tenant’s most recently completed audited statements of income, shareholder’s equity and cash flows statements, and (b) Tenant’s most recently completed balance sheet (audited or reviewed by an independent certified public accountant if available, and certified by an officer of Tenant, if not so reviewed or audited, as being true and correct in all material respects). Any such financial information may be relied upon by any actual or potential lessor, purchaser, or mortgagee of the Property or any portion thereof.

X. Xxxxxx requires, as a condition to the Lease being subordinate to the Mortgage, that its rights under the Lease be recognized.

E. Mortgagee, Landlord, and Tenant desire to confirm their understanding with respect to the Mortgage and the Lease.

NOW, THEREFORE, in consideration of the foregoing, the mutual covenants and agreements contained herein, and other valuable consideration, the receipt and adequacy of which are hereby acknowledged, and with the understanding by Tenant that Mortgagee will rely hereon in making and maintaining the Loan, Mortgagee, Landlord, and Tenant agree as follows:

1. The Lease is subordinate to the lien of the Mortgage and any renewal, substitution, extension or replacement thereof and each advance made thereunder as though said Mortgage, and each such renewal, substitution, extension or replacement were executed, recorded and the advance made before the execution of the Lease.

2. So long as Tenant is not in default (beyond any period expressed in the Lease within which Tenant may cure such default) in the payment of rent or in the performance or observance of any of the terms, covenants or conditions of the Lease on Tenant’s part to be performed or observed, (i) Tenant’s occupancy of the Demised Premises shall not be disturbed by Mortgagee, nor will Tenant’s rights under the Lease be impaired (except as expressly provided in this Agreement), in the exercise of any of its rights under the Mortgage during the term of the Lease or any extension or renewal thereof, made in accordance with the terms of the Lease, and (ii) Mortgagee will not join Tenant as a party defendant in any action or proceeding for the purpose of terminating Tenant’s interest and estate under the Lease because of any default under the Mortgage.

3. In the event any proceedings are brought for the foreclosure of the Mortgage, or if the Property or the Demised Premises are sold pursuant to the power of sale under the Mortgage, Tenant shall attorn to the purchaser upon any such foreclosure sale and shall recognize such purchaser thereafter as the Landlord under the Lease. Such attornment shall be effective and self-operative without the execution of any further instrument on the part of any of the parties hereto. Xxxxxx agrees, however, to execute and deliver at any time and from time to time, upon the request of any holder(s) of any of the indebtedness or other obligations secured by the Mortgage, or upon request of any such purchaser, (a) any reasonable instrument or certificate which, in the reasonable judgment of such holder(s), or such purchaser, may be necessary or appropriate in any such foreclosure proceeding or otherwise to evidence such attornment on the terms and conditions set forth in this Agreement, and (b) on the conditions set forth in the Lease applicable to estoppel certificates, an estoppel certificate regarding the status of the Lease, consisting of statements, if true (and if not true, specifying in what respect), (i) that the Lease is in full force and effect, (ii) the date through which rentals have been paid, (iii) the duration and date of the commencement of the term of the Lease, (iv) the nature of any amendments or modifications to the Lease, and (v) that to the best of Tenant’s knowledge, no default, or state of facts, which with the passage of time, or notice, or both, would constitute a default, exists on the part of either party to the Lease.

From and after any such succession, Mortgagee or such purchaser shall be bound to Tenant under all the terms, covenants and conditions of the Lease, and Tenant shall have the same remedies against Mortgagee, or such purchaser, for the breach of an agreement contained in the Lease that Tenant might have had under the Lease against Landlord if Mortgagee or such purchaser had not succeeded to the interest of Landlord; provided, however, that Mortgagee or such purchaser shall only be bound during the period of its ownership, all Tenant claims shall be satisfied only out of the interest, if any, of Mortgagee or such purchaser in the Property and the proceeds therefrom, and Mortgagee and such purchaser shall not be (a) liable for any act or omission of any prior landlord (including the Landlord) provided, that, nothing in this clause (a) being deemed to relieve Mortgagee or any such purchaser of its continuing obligations as landlord under the Lease with respect to the period from and after the date of such succession; or (b) liable for or incur any obligation with respect to the construction of the Property or any improvements therein (provided that nothing in this Agreement shall prohibit or delay Tenant from
