	2.1	Premises. 

 (a) Landlord hereby leases to Tenant and Tenant hereby leases from Landlord,
for the Term, subject to and with the benefit of the terms, covenants, conditions and provisions of this Lease, the Premises. Not included in the Premises are the roof, exterior walls, the common stairways, stairwells, elevators and elevator shafts,
and pipes, ducts, conduits, wires, and appurtenant fixtures serving exclusively or in common other parts of the Building, and if the Premises consist of less than the entire rentable area of any floor, the central core area of such floor, if any.

 (b) Tenant shall have, as an appurtenance to the Premises, rights to use in common with others, subject to reasonable rules and
regulations established from time-to-time by Landlord of which Tenant is given notice: (1) the common lobbies, hallways, stairways, loading docks and bays, and elevators of the Building; (2) common walkways necessary for access to the
Building; and (3) if the Premises consist of less than the entire rentable area of any floor, the common toilets and other common facilities in the central core area of such floor. 

(c) Landlord reserves the right from time-to-time the following rights: (1) to install, use, maintain, repair, replace and relocate for
service to the Premises and/or other parts of the Building the areas within the Premises above the dropped ceiling and below the floor for pipes, ducts, conduits, wires and appurtenant fixtures, (2) to alter or relocate any other common
facility, (3) to make any repairs and replacements to the Premises which Landlord is obligated to perform, and (4) in connection with any excavation made upon adjacent land of Landlord or others, to enter and to permit others to enter,
upon the Premises to do such work as the person causing such excavation deems necessary to preserve the walls of the Building from injury or damage and to support the same. 

(d) In connection with the exercise of the foregoing rights of access (excepting routine access such as access for providing cleaning, repair
or maintenance services, or other usual and customary services) Landlord shall provide Tenant notice pursuant to Section 6.1.6 and exercise reasonable efforts (i) to minimize interference with the usual and customary operations of the
Tenant in the Premises in accordance with the provisions of this Lease, and (ii) to cause any construction work performed in the Premises to be performed in a workmanlike manner. 

(e) As an appurtenance to the Premises, during the term, subject to the provisions of this Section 2.1(e), Tenant shall receive four
(4) parking passes for use in the Boston Harbor Garage. Tenant will pay to Landlord, as Additional Rent, the rate established by the operator of the Boston Harbor Garage from time to time for such parking passes. Notwithstanding the foregoing,
if at any time during the Term such parking passes are not available in the Boston Harbor Garage, then in lieu thereof Landlord shall provide Tenant with four (4) parking passes for use at a comparable parking garage located within a four
(4) block radius of the Building, and Tenant will pay to Landlord, as Additional Rent, the rate established by the operator of such garage from time to time for such parking passes. 

  
 -6- 








 (f) Tenant shall have, as an appurtenance to the Premises, subject to reasonable rules and
regulations established from time-to-time by Landlord and notice of which is provided to Tenant, the right to install, operate, and maintain an antenna, satellite dish or similar telecommunication equipment on the roof of the Building, together with
lines and cables connecting such equipment in the existing risers of the Building (collectively, the “Rooftop Equipment”). All Rooftop Equipment (including, the size, location, weight and manner of attachment thereof) and any penetrations
of, or changes, alterations or other improvements on or to the roof of the Building, shall be subject to the prior approval of Landlord in each instance, such approval not to be unreasonably withheld. Tenant shall be solely and exclusively
responsible for all costs, expenses and charges, of every kind, of installing, operating, maintaining, repairing, replacing, and removing the Rooftop Equipment and Landlord shall have no liability or obligation in connection therewith. If, in the
reasonable judgment of Landlord, any electrical, electromagnetic, radio frequency or other interference shall result from the operation of any of the Rooftop Equipment, and such interference has not been corrected to the reasonable satisfaction of
Landlord within thirty (30) days after notice thereof to Tenant (which notice shall be accompanied by a reasonably detailed technical analysis as to the basis of Landlord’s judgment), then Landlord may require that Tenant immediately
remove from the specific item of equipment causing such interference. Tenant shall, at its sole cost and expense, and at its sole risk, install, operate and maintain the Rooftop Equipment in a good and workmanlike manner, and in compliance with all
electric, communication, and safety codes, ordinances, standards, regulations and requirements, now in effect or hereafter promulgated, including those established by the Federal Communications Commission (the “FCC”), the Federal Aviation
Administration (“FAA”) or any successor agency of either the FCC or FAA, the City of Boston, and the rules and regulations adopted in FCC document OET 65 (which rules and regulations have also been adopted by OSHA). Landlord shall not be
liable to Tenant for any stoppages or shortages of electrical power furnished to the Rooftop Equipment or to the roof area as a result of any act, omission or requirement of the public utility serving the Building, or the act or omission of any
other tenant, invitee or licensee or their respective agents, employees or contractors, or for any other Force Majeure Event. Neither Landlord nor its agents shall have any responsibility or liability for the conduct or safety of any of
Tenant’s representatives, repair, maintenance and engineering personnel while in or on any part of the roof area. Tenant shall have no right of access to the roof of the Building unless Tenant has given Landlord reasonable advance notice and
unless Tenant’s representatives are accompanied by a representative of Landlord. Landlord will make a representative available to Tenant (i) during Ordinary Business Hours upon reasonable advance notice and (ii) during emergencies, as
soon as practicable (taking into account the circumstances) after receipt of a request from Tenant. At the expiration or prior termination of this Lease, Tenant shall remove all of the Rooftop Equipment (including all cables and conduits


  
 -7- 








 
installed in connection therewith) and shall be responsible for the cost of repairing any damage to the Building caused by the installation or the removal of the Rooftop Equipment. Landlord shall
have the right, upon thirty (30) days notice to Tenant, relocate the Rooftop Equipment to another area on the roof of the Building equally suitable for Tenant’s use. In such event, Landlord may, at its sole cost and expense, relocate the
Rooftop Equipment. 
  

	2.2	Term. The Term shall begin on the Commencement Date and shall continue to the Expiration Date, unless sooner terminated as hereinafter provided. Without limiting the effectiveness of such dates, upon request of
either party, Landlord and Tenant shall execute and deliver a Commencement Date Agreement, in the form attached hereto as Exhibit C, confirming the Commencement Date and the Expiration Date. 


ARTICLE 3 
 Condition of
Premises; Tenant’s Work 
  

	3.1	Condition of Premises. Landlord shall deliver possession of the Premises to Tenant on the Commencement Date free of all tenants and occupants and otherwise in compliance with this Lease. Tenant has inspected the
Premises and agrees (a) to accept possession of the Premises in the condition existing as of the Commencement Date, in “as is” condition, (b) that neither Landlord nor any of Landlord’s agents have made any representations
or warranties with respect to the Premises or the Building, and (c) Landlord has no obligation to perform any work, supply any materials, incur any expense or make any alterations, additions or improvements to the Premises to prepare the
Premises for Tenant’s use and occupancy. Tenant shall, at its own cost and expense, in accordance with and subject to the terms and provisions of this Lease, perform or cause to be performed any and all work necessary to prepare the Premises
for Tenant’s initial occupancy (“Tenant’s Work”). The Building is equipped with telecommunications systems for RCN and Verizon. Landlord shall provide Tenant and/or Tenant’s telecommunications companies with the access to
the existing conduits and chases of the Building for the installation and operation of Tenant’s telecommunication systems, including but not limited to voice, video, data and other telecommunications services; provided, however, that any such
access, installation and operation shall be subject to Landlord’s prior approval in each case, which approval will not be unreasonably withheld, conditioned or delayed. Tenant’s occupancy of any part of the Premises shall be conclusive
evidence, that Tenant has accepted possession of the Premises in its then-current condition, and that at the time such possession was taken, the Premises and the Building were in a good and satisfactory condition as required by this Lease.

	3.3	Plans and Specifications. (a) If Tenant elects, in its sole discretion, to perform any Tenant’s Work, then Tenant shall prepare, at the sole cost and expense of Tenant, and furnish to Landlord for its
approval, architectural, mechanical, 


  
 -8- 









	 	
electrical, plumbing, fire protection and structural engineering schematic design documents, design development documents and final construction documents for the Tenant’s Work (such
documentation and the constituent items thereof are referred to herein collectively and respectively as the “Proposed Documents”; and the Proposed Documents, after approval by Landlord are referred to herein as the “Construction
Documents”). Tenant will submit to Landlord and Landlord’s architect (i) four (4) sets of paper versions of the Construction Documents, and (ii) electronic versions of the Construction Documents in AutoCad (dwg) format
prepared by Tenant’s Architect. The Tenant’s Work shall be performed in accordance with the Construction Documents and the “Standard Tenant Fit-Out Specifications for 255 State Street” attached hereto as Exhibit F and
incorporated herein by this reference (as the same may be updated, amended, modified and supplemented by Landlord from time-to-time, the “Standard Tenant Fit-Out Specifications”). There shall be no requirement for Tenant to use any
particular building standard materials or items; however, the Tenant’s Work shall be first-class in all respects and shall be consistent with and complementary to the first-class standards of the Building. Tenant shall cause Tenant’s
Architect to perform all architectural services typically and reasonably required under typical construction contracts for similar leasehold improvements. Such services shall include, without limitation, all certifications typically and reasonably
required to be provided by the architect for similar leasehold improvements. Tenant shall be solely responsible for the cost of all architectural and engineering services required for the Tenant’s Work. The Construction Documents for
Tenant’s Work shall comply with all applicable laws, ordinances and regulations (including, without limitation, the applicable requirements of the Americans with Disabilities Act of 1990, as amended from time to time, and the regulations
promulgated thereunder (collectively, the “ADA”)) and shall be in a form satisfactory to appropriate governmental authorities responsible for issuing the permits, approvals and licenses required for construction of Tenant’s Work.
Tenant’s interior furnishings (i.e., specifications, coordination, supply and installation of furniture, furnishings, telephone and moveable equipment and security systems and equipment) will be the responsibility of Tenant. Tenant will be
responsible for obtaining all permits and approvals for the Tenant’s Work, including, without limitation, a building permit and all applicable electrical and plumbing permits from the City of Boston Department of Inspectional Services.


 (b) All requests for amendments, changes, change orders, or alterations to the Construction Documents (each, a “Change
Order”) shall require Landlord’s approval, which approval shall not be unreasonably withheld or conditioned and shall be given within the timeframe set forth below (it being understood that any denial shall state Landlord’s objections
with specificity so that they may be addressed by Tenant). Landlord’s approval process for a requested Change Order will also include review of Tenant’s fire protection design by Factory Mutual Global representing Landlord’s insurance
underwriter. Landlord will give Tenant notice (a “Landlord Plan Notice”) of any objections it may have with respect to any requested Change Order within five (5) business days after receipt by Landlord and Landlord’s Architect of
four (4) sets of paper versions of the 

  
 -9- 








 
applicable Construction Documents affected by such Change Order and an electronic version of such Construction Documents. Landlord shall not be deemed unreasonable for withholding approval of any
such Change Order which (i) involve or are reasonably anticipated to affect any structural or exterior element of the Building or any portion thereof, (ii) are anticipated to, in Landlord’s reasonable opinion, materially adversely
affect the value of the Building or any portion thereof, (iii) are reasonably anticipated to materially adversely affect the proper functioning of the building systems or other facilities, (iv) will materially increase the cost of
construction or insurance on the Building or any portion thereof, or may materially increase the Operating Costs or Taxes, or (v) do not incorporate any changes requested by Factory Mutual Global and contained in the Landlord Plan Notice.
Concurrently with its review of proposed Change Orders, Landlord will notify Tenant as to which of the proposed installations and improvements shown on the applicable Change Order constitute Specialty Alterations (as defined in Section 1.3)
which Tenant will be required to remove at the expiration of the Term. 
 (c) Tenant shall cause the Change Order and any affected
Construction Documents to be revised in a manner sufficient to remedy Landlord’s objections and/or respond to Landlord’s concerns and to be redelivered to Landlord as soon as reasonably possible after Tenant is given a Landlord Plan
Notice. Tenant shall exercise diligent efforts to revise the applicable Construction Documents to address the objections contained in each Landlord Plan Notice. 

(d) Landlord’s approval of any plans and specifications with respect to Tenant’s Work furnished to and approved by Landlord, or of
any changes thereto, shall in no way be deemed an agreement by Landlord that the work contemplated therein fulfills the requirements of Section 3.3(a) hereof. Tenant shall be responsible for the design of the Tenant’s Work. 

 

	3.4	Performance of TIW; Tenant’s Contractor. Tenant agrees to employ for the Tenant’s Work a responsible general contractor approved by Landlord, which general contractor shall (1) employ and hire
subcontractors who employ union labor to do all union trade work, (2) employ and hire subcontractors who employ labor which will work without interference with other labor working in the Building for any work that is not union trade work, and
(3) obtain and maintain the insurance required by Section 6.2.5 of this Lease. Tenant shall submit certificates evidencing such insurance coverage to Landlord prior to the commencement of the Tenant’s Work. Tenant shall obtain all
necessary governmental licenses, approvals and permits therefor and deliver to Landlord the statements and insurance certificates required hereunder and under 6.2.5 of this Lease on or before the commencement of the Tenant’s Work. Promptly
thereafter (subject to delays to the extent caused by Force Majeure Events, provided that tenant uses diligent efforts to minimize the duration and extent of the affect of such Force Majeure Event), Tenant shall commence and diligently prosecute to
completion the Tenant’s Work in accordance with the Construction Documents in a good and workmanlike manner employing materials of good quality and in 


  
 -10- 









	 	
compliance with all applicable zoning, building, fire, health and other codes, regulations, ordinances and laws. Tenant shall be responsible for all costs and expenses of performing Tenant’s
Work. The Tenant’s Work shall otherwise be performed in accordance with the applicable provisions of this Lease, including, without limitation, the provisions of Section 6.2.5; provided, however, in the event of any conflict or
inconsistency between the provisions of this Section 3.4 and Section 6.2.5 of this Lease the terms of this Section 3.4 shall govern and control. Tenant shall provide a project manager who will be the point of contact with
Landlord’s Project Manager for all matters dealing with the design and construction of the Tenant’s Work. Landlord hereby designates Tom Walsh as “Landlord’s Project Manager.” 


 

	3.5	Mechanic’s Liens. Tenant hereby indemnifies and holds harmless Landlord from and against any liabilities and/or obligations for any and all liens or encumbrances filed against the Property or any part
thereof or interest therein arising out of or resulting from the Tenant’s Work or any other work performed by Tenant under this Lease. Tenant, at its expense, shall procure the discharge of all such liens and encumbrances within ten
(10) days after the filing of any such lien or encumbrance against the Premises and/or the Property or any part thereof. If Tenant shall fail to cause any such lien or encumbrance to be discharged within such ten (10) day period, then, in
addition to any other right or remedy, Landlord may, but shall not be obligated to, discharge the same either by paying the amount claimed to be due or by deposit or bonding proceedings, and in any such event Landlord shall be entitled, if it
elects, to compel the prosecution of an action for the foreclosure of such lien and to pay the amount of the judgment in favor of the lien with interest, costs and allowances. Without limiting the foregoing, any amount so paid by Landlord, and all
costs and expenses incurred by Landlord in connection therewith, shall constitute Additional Rent under this Lease and shall be paid by Tenant to Landlord on demand. 


ARTICLE 4 
 Rent 

 

	4.1	Payment of Rent: Fixed Rent. (a) Tenant covenants and agrees to pay to Landlord, without notice or demand and without abatement, offset, deduction or counterclaim, at the Original Address of Landlord, or at
such other place or to such other person or entity as Landlord may from time-to-time direct in writing: (i) Fixed Rent at the Annual Fixed Rent Rate, in equal monthly installments at the Monthly Fixed Rent Rate (which is 1/12th of the Annual
Fixed Rent Rate), (and for any portion of a calendar month following the Commencement Date or at the end of the Term, at that rate prorated on a daily basis payable for such portion), in advance, on the first day of each calendar month during the
Term, commencing on the Commencement Date; and (ii) Additional Rent, in the amounts, at the times and in the manner set forth in this Lease. The Fixed Rent and Additional Rent payable hereunder sometimes are referred to in this Lease
collectively as the “Rent.” 

 (b) If Landlord shall give notice to Tenant that all Rent and other payments due
hereunder are to be made to Landlord by electronic funds transfers or by similar means, then Tenant shall make all such payments as shall be due after receipt of such notice by means of such electronic funds transfers or such similar means as
designated by Landlord. 

  
 -11- 









	4.2	Additional Rent. Tenant covenants and agrees to pay the following, as Additional Rent: 

  

	4.2.1	Real Estate Taxes. (a) If for any Tax Year during the Term the Taxes exceed Base Taxes then Tenant shall reimburse Landlord, as Additional Rent, for Tenant’s Percentage of such excess. The Additional
Rent payable by Tenant under the preceding two sentences is referred to herein collectively as the “Tax Excess.” Tenant shall remit to Landlord, on the first day of each calendar month, estimated payments on account of Tax Excess, such
monthly amounts to be sufficient to provide Landlord, by the time real estate tax payments are due and payable to any governmental authority responsible for collection of same, a sum equal to the Tax Excess, as reasonably estimated by Landlord from
time-to-time on the basis of the most recent tax data available. If the total of such monthly payments for any Tax Year is greater than the actual Tax Excess for such Tax Year, then promptly after the expiration of such Tax Year and the
determination of the actual amount of Tax Excess for such Tax Year, Landlord shall pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.1, the difference; if the total of such payments is
less than the actual Tax Excess for such Tax Year, then Tenant shall pay the difference to Landlord not more than ten (10) days after Landlord delivers to Tenant an itemized statement of the Tax Excess. 


(b) If, after Tenant shall have made reimbursement to Landlord pursuant to this subsection 4.2.1, Landlord shall receive a refund of any
portion of Taxes paid by Tenant with respect to any Tax Year during the Term hereof, whether as a result of an abatement of such Taxes by legal proceedings, settlement or otherwise (without Landlord having any obligation to undertake any such
proceedings), Landlord shall promptly pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.1, the Tenant’s Percentage of the refund (less the proportional pro rata expenses, including,
without limitation, attorneys’ fees and appraisers’ fees, incurred in connection with obtaining any such refund. 
 (c) If the Term
of this Lease shall commence, or shall end (by reason of expiration of the Term or earlier termination pursuant to the provisions hereof), on any date other than the first or last day of the Tax Year, or should the Tax Year or period of assessment
of real estate taxes be changed or be more or less than one (1) year, as the case may be, then the amount of Tax Excess payable by Tenant for such year shall be appropriately apportioned on the basis of daily prorations and adjusted
accordingly. 

  
 -12- 








 (d) The term “Taxes” shall mean all ad valorem real estate and personal property taxes,
assessments, betterments and other charges and impositions (including, but not limited to, fire protection service fees and similar charges) levied, assessed or imposed at any time and from time-to-time during the Term by any governmental authority
upon or against the Property and/or any part thereof, or taxes in lieu thereof, and in the case of personal property taxes, those taxes payable with respect to personal property located at and used in connection with the maintenance and operation of
the Property. “Taxes” shall also include all taxes and payments assessed, levied, imposed or otherwise payable in lieu of the foregoing, all costs and expenses (including reasonable attorneys fees) incurred in contesting any of the
foregoing, and all other additional types of taxes assessments, levies, impositions, fees and charges however described or imposed upon the Property and/or the Landlord with respect to the Property. If, at any time during the term of this Lease, any
tax or excise on rents or other taxes, however described, are levied or assessed against Landlord with respect to the Rent reserved hereunder and/or the ownership of the Property, either wholly or partially in substitution for, or in addition to, ad
valorem real estate taxes assessed or levied on the Property and/or any part thereof, such tax or excise on rents shall be included in Taxes; provided however, Taxes shall not include franchise, estate, inheritance, succession, capital levy,
transfer, net income or excess profits taxes assessed on Landlord. Taxes shall include any estimated payment made by Landlord on account of a fiscal tax period for which the actual and final amount of taxes for such period has not been determined by
the governmental authority as of the date of any such estimated payment. 
  

	4.2.2	Personal Property Taxes. Tenant shall pay all taxes, assessments, betterments and other charges and impositions charged, assessed or imposed upon the personal property, fixtures and equipment of Tenant in or upon
the Premises prior to the due date thereof. 

  

	4.2.3	Operating Costs. (a) If for any calendar year during the Term the Operating Costs exceed the Base Operating Costs, then Tenant shall reimburse Landlord, as Additional Rent, for Tenant’s Percentage of
such excess (such amount being hereinafter referred to as the “Operating Costs Excess”). Tenant shall remit to Landlord, on the first day of each calendar month, estimated payments on account of Operating Costs Excess, in monthly amounts
reasonably estimated by Landlord from time-to-time to be sufficient to provide Landlord, by the end of the calendar year, a sum equal to the Operating Costs Excess for such calendar year. If, at the expiration of any respective calendar year the
total of such monthly payments made by Tenant is greater than the actual Operating Costs Excess for such year, then promptly after the expiration of such calendar year and the determination of the actual amount of Operating Costs Excess, Landlord
shall pay to Tenant or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.3, the difference; if the total of such payments is less than the Operating Costs Excess for such year, then Tenant shall pay the
difference to Landlord within not more than thirty (30) days after the date Landlord furnishes to Tenant an itemized statement of the Operating Costs Excess. Landlord shall 


  
 -13- 









	 	
deliver the annual statement of actual Operating Costs Excess not later than one hundred eighty (180) days after the expiration of the respective calendar year. Any reimbursement for
Operating Costs due and payable by Tenant with respect to periods of less than twelve (12) months shall be equitably prorated. 


(b) The term “Operating Costs” shall mean all costs or expenses of every kind and nature paid or incurred by Landlord in connection
with the operation, cleaning, management, maintenance, repair and upkeep of the Property, including, without limitation, all costs of maintaining and repairing the Property (including snow removal, security, operation and repair of heating and
air-conditioning equipment, elevators, lighting and any other building equipment or systems) and of all repairs and replacements (other than repairs or replacements for which Landlord has received full reimbursement from contractors, other tenants
of the Building or from others) required or desirable in order to keep the Property in good working order, repair, appearance and condition; all costs, including material and equipment costs, for cleaning and janitorial services to the Building
(including window cleaning of the Building); all premiums and costs of insurance carried by Landlord relating to the Property; all costs related to provision of heat (including oil, electric, steam and/or gas), air-conditioning, ventilation, and
water (including sewer charges) and other utilities to the Building (exclusive of reimbursement to Landlord for any of same received as a result of direct billing to any tenant); payments under all service contracts relating to the foregoing; all
compensation, fringe benefits, payroll taxes and worker’s compensation insurance premiums related thereto with respect to any employees (but not above the grade of general manager) of Landlord or its affiliates or manager engaged in security
and maintenance of the Property; attorneys’ fees and disbursements (exclusive of any such fees and disbursements incurred in tax abatement proceedings or the preparation of leases or disputes with tenants) and auditing and other professional
fees and expenses; shuttle services; management fees not in excess of 3% of gross rent receipts for the Building for the applicable year; fire protection service fees and similar governmental charges not included in Taxes; and the portion fairly
allocable to the Property of any and all of the foregoing costs incurred with regard to the operation, maintenance and repair of any facilities shared by the Property with any other properties. 

(c) There shall not be included in such Operating Costs the following: (1) brokerage fees (including rental fees) related to the operation
of the Building; (2) interest and depreciation charges incurred on the Property; (3) expenditures made by Tenant with respect to (a) cleaning, maintenance and upkeep of the Premises, or (b) the provision of electricity to the
Premises; (4) any ground lease rent; (5) costs of leasing space, including advertising and leasing commissions; (6) costs of services provided by affiliates of Landlord (other than the management fees set forth above) to the extent
such costs exceed market competitive costs for such services for owner managed buildings; (7) Capital Expenditures (as hereinafter defined) which are required in order to cause the Building to comply with Requirements that are effective and
applied to the Building (whether through adoption, promulgation, application, interpretation or otherwise) as of the date of 

  
 -14- 








 
this Lease and rent for items which if purchased, rather than rented, would not be includable in Operating Expenses pursuant to Section 4.2.3(d); (8) bad debt expenses and payments of
principal, interest or mortgage charges, or other costs of financing or refinancing or brokerage commissions, or the costs of selling, syndicating, financing, mortgaging or hypothecating Landlord’s interest in the Property, or the costs of
defending any lawsuits with mortgagees; (9) the cost of repairs or other work caused by any insured casualty or the exercise of the right of eminent domain, to the extent the Landlord is reimbursed by insurance awards, rebates or condemnation
proceeds; (10) leasing commissions, brokerage fees, legal fees, advertising costs and disbursements and other expenses incurred in connection with negotiations or disputes with other tenants or occupants, or prospective tenants or occupants;
(11) the costs of renovating or otherwise improving, decorating, painting or redecorating premises for other tenants or other occupants of the Building; (12) any fines or penalties incurred by Landlord as a result of a violation by
Landlord of applicable laws or governmental rule or authority; (13) costs of installing sculpture, paintings or other objects of art in common areas, except to the extent required to maintain the Building in first-class condition;
(14) wages, salaries or other compensation paid to any executive employees above the grade of general manager, except that if any such employee performs a service which would have been performed by an outside consultant, the compensation paid
to such employee for performing such service shall be included in Operating Costs; (15) costs or fees relating to the defense of the title or interest of Landlord in the Property; (16) income, excess profits, franchise taxes or other taxes
assessed on the income of the Landlord from the Property; (17) costs of maintaining the legal entity constituting the Landlord; (18) costs of the charitable or political contributions of the Landlord; (19) costs incurred by Landlord
to the extent that Landlord is reimbursed by third parties; (20) third-party management fees in excess of the percentage set forth in Section 4.2.3(b) and management fees paid or charged by affiliates of Landlord in excess of 3% of gross
rent receipts; or (21) fines, penalties or interest to the extent caused by the negligence or willful misconduct of Landlord or its agents or employees. 

(d) If, during the Term of this Lease, Landlord shall replace any capital items or make any capital expenditures for the Property
(collectively, “Capital Expenditures”), then the “annual charge-off” of such Capital Expenditure shall be included in Operating Costs for each calendar year in which such Capital Expenditure is made, and for each subsequent
calendar year only if (i) the Capital Expenditure is reasonably intended to effect savings in Operating Costs, or (ii) is made to comply with a Requirement which becomes effective (whether through adoption, promulgation, application,
interpretation, or otherwise) after the date of this Lease. The “annual charge-off” shall be determined by (i) dividing the original cost of the Capital Expenditure by the number of years of useful life thereof (which useful life
shall be determined by Landlord in accordance with generally accepted accounting principles and practices in effect at the time of acquisition of the capital item or making of a capital expenditure); and (ii) adding to such quotient an interest
factor computed on the unamortized balance of such Capital Expenditure based upon an interest rate reasonably determined by 

  
 -15- 








 
Landlord as being the interest rate then being charged for long-term mortgages by institutional lenders on similar properties within the locality in which the Building is located; provided,
however, if Landlord reasonably concludes on the basis of engineering estimates that such Capital Expenditure will effect savings in Operating Costs and that such annual projected savings will exceed the annual charge-off of such Capital Expenditure
computed as aforesaid, then the annual charge-off shall be determined by (i) dividing the original cost of such Capital Expenditure by the number of years over which the projected amount of such savings shall fully amortize the cost of such
Capital Expenditure; and (ii) by adding the interest factor, as aforesaid. 
 (e) If during all or any portion of any year for which
Operating Costs are being computed, less than 95% of the rentable area of the Building is occupied by tenants, or Landlord does not furnish any particular item(s) of work or service (which would otherwise constitute an Operating Cost) to any
leasable areas of the Building, then for purposes of calculating Operating Costs for such year, the actual Operating Costs incurred for such year or portion thereof shall be reasonably extrapolated by Landlord to be the estimated Operating Costs
that would have been incurred if 95% of the rentable area of the Building had been occupied by tenants and such item(s) of work and services were being supplied to tenants occupying 95% of the rentable area of the Building, and for the purposes of
this Section 4.2.3, such extrapolated amount shall be deemed to be the Operating Costs for such year or portion thereof. 
 (f) Each
statement of Operating Costs delivered to Tenant shall constitute an account stated between Landlord and Tenant and shall be conclusively binding upon Tenant, unless Tenant (i) pays to Landlord when due the amount set forth in such statement,
without prejudice to Tenant’s right to dispute such statement, and (ii) within one hundred eighty (180) days after such statement is sent, sends a written notice to Landlord objecting to such statement and specifying the reasons
therefor, in which event, upon request, Tenant may, at its sole cost and expense, audit the books and records pertaining to the Operating Costs for the subject year. Said audit shall be performed either (i) at a mutually satisfactory time at
Landlord’s offices in Boston, Massachusetts, or (ii) after physical or electronic delivery to Tenant of the relevant documents. Tenant agrees that Tenant will not employ, in connection with any such audit or any dispute under this Lease,
any person or entity who is to be compensated in whole or in part, on a contingency fee basis. In connection with any such audit, Tenant, such accountants and all consultants and agents of Tenant shall keep all information confidential and shall
execute and deliver to Landlord a commercially reasonable and mutually acceptable confidentiality agreement, whereby such parties agree not to disclose to any third party any of the information obtained in connection with such audit. Tenant shall
pay the fees and expenses relating to such audit, unless it is conclusively determined that Landlord overstated Operating Costs by more than 5% for such year, in which event Landlord shall reimburse Tenant for the reasonable out-of-pocket costs
incurred by Tenant in such audit. 

  
 -16- 









	4.2.4	Insurance. Tenant shall, at its cost and expense, obtain and maintain throughout the Term, the following insurance protecting Landlord and all Landlord Affiliates, as requested by Landlord from time-to-time:


  

	 	4.2.4.1	Commercial general liability insurance, in the broadest and most comprehensive form generally available from time-to-time, naming Tenant as insured, and Landlord, Landlord’s managing agent, the Landlord Affiliates
(of which Tenant has been given notice), and any mortgagee of which Tenant has been given notice as additional insureds, and indemnifying the parties so named on an occurrence basis against all claims and demands for death or any injury to persons
or damage to property which may be claimed to have occurred on the Premises (or the Property, insofar as used by customers, employees, servants or invitees of the Tenant), in amounts which shall, at the beginning of the Term, be at least equal to
the limits set forth in Section 1.1, and, which, from time to time during the Term, shall be for such higher limits, if any, as Landlord determines in its reasonable discretion as are customarily carried in the area in which the Premises are
located on property similar to the Premises and used for similar purposes. 

  

	 	4.2.4.2	Insurance against loss or damage by fire, and such other risks and hazards as are insurable under then available standard forms of “all risk” property insurance policies with extended coverage, insuring all of
Tenant’s furniture, furnishings, fixtures, and equipment, for the full insurable value thereof or replacement cost value thereof, having a deductible amount, if any, of not greater than $25,000.00 per annum; 


 

	 	4.2.4.3	During the performance of any Alterations (including the Tenant’s Work), until completion thereof, builder’s risk insurance on an “all risk” basis and on a completed value form, for full replacement
value covering the interests of Landlord and Tenant (and their respective contractors and subcontractors), any superior mortgagee and any superior lessor in all work incorporated in the Building and all materials and equipment in or about the
Premises; 

  

	 	4.2.4.4	Workers’ compensation insurance, in amounts and with coverages as required by law; 

  

	 	4.2.4.5	Business interruption insurance, which may be included within a blanket limit covering multiple office locations including the Premises, in commercially reasonable amounts; and 


 

	 	4.2.4.6	Such other insurance, in such amounts and with such coverages as Landlord may reasonably require from time to time, provided that such coverages are consistent with coverages then customarily being required by other
landlords of comparable buildings in Boston, Massachusetts. 


  
 -17- 









	 	4.2.4.7	All such policies shall be obtained from insurance companies with A.M. Best ratings of “A-” or better, Class VIII or larger, and with S&P ratings of “AA” or better. All such insurance companies
shall be qualified to do business and in good standing in the Commonwealth of Massachusetts. All such insurance companies and the amount of insurance allocated thereto shall be subject to Landlord’s approval, which approval shall not be
unreasonably withheld. Tenant agrees to furnish Landlord with certificates evidencing all such insurance prior to the beginning of the Term hereof and evidencing renewal thereof at least thirty (30) days prior to the expiration of any such
policy. Each such policy shall be non-cancelable with respect to the interest of Landlord without at least ten (10) days prior written notice thereto. In the event provision for any such insurance is to be by a blanket insurance policy, the
policy shall allocate a specific and sufficient amount of coverage to the Premises. 

  

	 	4.2.4.8	All insurance which is carried by either party with respect to the Building, the Premises or furniture, furnishings, fixtures, or equipment therein or alterations or improvements thereto, whether or not required, shall
include provisions which either designate the other party as one of the insured or deny to the insurer acquisition by subrogation of rights of recovery against the other party to the extent such rights have been waived by the insured party prior to
occurrence of loss or injury. In the event that extra premium is payable by either party as a result of this provision, the other party shall reimburse the party paying such premium the amount of such extra premium. If at the request of one party,
this non-subrogation provision is waived, then the obligation of reimbursement shall cease for such period of time as such waiver shall be effective, but nothing contained in this subsection shall derogate from or otherwise affect releases elsewhere
herein contained of either party for claims. Each party shall be entitled to have certificates of any policies containing such provisions. Each party hereby waives all rights of recovery against the other for loss or injury against which the waiving
party is protected by insurance containing such provisions, reserving, however, any rights with respect to any excess of loss or injury over the amount covered by such insurance. Tenant shall not acquire as insured under any insurance carried by or
on behalf of the Landlord with respect to the Premises any right to participate in the adjustment of loss or to receive insurance proceeds and agrees upon request promptly to endorse and deliver to Landlord any checks or other instruments in payment
of loss in which Tenant is named as payee. 

  

	4.2.5	Utilities. Tenant shall pay to Landlord, as Additional Rent, the Condenser Water Charge for condenser water supplied by Landlord pursuant to Section 5.1.1, the Overtime HVAC Charge for the Overtime HVAC
service provided by Landlord pursuant to Section 5.1.2, and all charges for electricity supplied by Landlord to the Premises, if any (which may include electricity for ventilation and cooling, including reheat coils, fan boxes, compressors and
refrigerating units serving the Premises). Tenant shall also pay, to the appropriate third party, all charges for 


  
 -18- 









	 	
telephone and other utilities or services not supplied by Landlord pursuant to Sections 5.1, whether designated as a charge, tax, assessment, fee or otherwise, all such charges to be paid as the
same from time to time become due. Except as otherwise provided in Article 5, it is understood and agreed that Tenant shall make its own arrangements for the installation or provision of all such utilities and that Landlord shall be under no
obligation to furnish any utilities to the Premises and shall not be liable for any interruption or failure in the supply of any such utilities to the Premises. 

  

	4.3	Late Payment of Rent. If Tenant shall fail to pay any installment of Rent more than two (2) days after the date that such Rent was due, and if on a prior occasion in the twelve (12) month period
immediately preceding such date Tenant also failed to pay any installment of Rent more than two (2) days after the date that such Rent was due, then in addition to the outstanding amounts, Tenant shall pay Landlord a late payment fee equal to
5% percent of the overdue payment. 

 ARTICLE 5 

Landlord’s Covenants 
  

	5.1	Affirmative Covenants. Landlord covenants with Tenant: 

  

	5.1.1	Condenser Water. To furnish condenser water and a condenser water connection to the heat pump and related equipment currently installed by Tenant in the Premises. Tenant shall pay to Landlord the “Condenser

maintain the meter in good working order and repair. If Tenant fails to pay such charges on a timely basis, then Landlord may pay such charges directly to the utility company and Tenant shall reimburse Landlord as additional rent for all amounts
expended by Landlord in connection

therewith within ten (10) days after receipt of a bill therefor. Tenant shall at all times comply with the rules and regulations of the utility company supplying electricity to the Building.
Tenant shall not use any electrical equipment which, in Landlord’s reasonable judgment, would exceed the capacity of the electrical equipment serving the Premises. 


 

	5.1.4	Cleaning. To provide cleaning to the Premises (excluding any portions thereof used for the storage, preparation, service or consumption of food) and the common areas of the Building substantially in accordance
with the Cleaning Specifications attached hereto as Exhibit D and incorporated herein by this reference. Notwithstanding the foregoing, Tenant, at Tenant’s expense, shall cause any portions of the Premises used for the storage,
preparation, service or consumption of food or beverages to be cleaned daily in a manner reasonably satisfactory to Landlord, and to be treated against infestation by vermin, roaches or rodents, on a regular basis. Without limiting the foregoing,
except as set forth above, in no event shall any portion of the Premises (other than a kitchenette area) be used for the storage, preparation, service or consumption of food or beverages. 


 

	5.1.5	Water. To furnish water to the Premises for ordinary cleaning, lavatory and toilet facilities. 

  

	5.1.6	Passenger Elevator Service. To furnish passenger elevator service from the lobby to the Premises. 

  

	5.1.7	Security and Access. To furnish at least one (1) attendant in the Building during Normal Business Hours, and a card access control system for access to the Building and Premises after Normal Business Hours,
including, without limitation, elevator access cards if needed for elevator access to floors. Tenant understands that except as expressly set forth in this Section 5.1.7, Landlord will not provide Tenant with any security guards or alarm or
security systems of any kind or nature. Notwithstanding the foregoing, in no event shall Landlord have any liability or obligation to Tenant arising from any claims for loss, injury or damage to persons or property in connection therewith. Subject
to reasonable security measures and Force Majeure Events, or when precluded by casualties or eminent domain events, Tenant and its employees shall have access to the Building and Premises twenty-four (24) hours per day, seven (7) days per
week, three-hundred-sixty-five (365) days per year during the Term. 

  

	5.1.8	Repairs. Except as otherwise expressly provided herein, to make such repairs and replacements to the roof, exterior walls, exterior windows, floor slabs and other structural components of the Building, and to the
common areas, facilities and plumbing, electrical, heating, ventilating and air-conditioning systems of the Building (including without limitation such base building electrical, heating, ventilating and air-conditioning systems that serve the
Building and the Premises) as may be necessary to keep them in good repair and condition (exclusive of equipment installed by Tenant and except for those repairs required to be made by Tenant pursuant to Section 6.1.3 hereof, and repairs or
replacements occasioned by any negligence of Tenant, its servants, agents, customers, contractors, employees, invitees, or licensees). 


  
 -20- 









	5.1.9	Telecommunications. To permit Tenant, at its sole cost and expense, to install in a riser location (or locations) designated by Landlord in its reasonable discretion, its telecommunications lines, cables and
equipment (“Tenant’s Telecommunications Equipment”). Except with respect to Tenant’s Telecommunications Equipment installed as part of the Tenant’s Work, which shall be subject to prior approval by Landlord pursuant to
Section 3.3, the capacity, size, location and dimensions of such risers and of each element of the Tenant’s Telecommunications Equipment shall be subject to Landlord’s approval, which approval will not be unreasonably withheld,
conditioned or delayed. Tenant’s Telecommunications Equipment shall be considered to be an Alteration for all purposes under this Lease, and shall comply with the provisions of Section 6.2.5 and all of the other provisions of this Lease.
Tenant shall remove the Tenant’s Communication Equipment upon the expiration or earlier termination of this Lease. 

  

	5.1.10	Property Insurance. To maintain throughout the Term, as the same may be extended pursuant to section 2.3 of this Lease, property insurance insuring the Building against loss or damage by fire and other perils
covered under so-called “all risk,” vandalism, malicious mischief coverage, boiler and machinery coverage and such other insurable hazards and contingencies as are from time to time normally insured against by owners of comparable
first-class multi-tenant office buildings in the City of Boston, in an amount approximately equal to the full replacement cost thereof, including, without limitation, builder’s risk coverage for the Tenant’s Work (subject to such
commercially reasonable deductibles as Landlord may elect from time to time). From time to time upon the reasonable request of Tenant Landlord shall deliver to Tenant certificates evidencing all such insurance. All policies of insurance maintained
by Landlord shall contain the same waiver of subrogation provisions for the benefit of Tenant as Tenant is required to obtain in its insurance policies for the benefit of Landlord. 


 

	5.1.11	Representations of Landlord. Landlord represents and warrants to Tenant as follows: (i) Landlord is the fee simple and record owner of the Property and the Building, and has the full right, power and
authority to execute, deliver and perform its obligations under this Lease and has obtained all consents and taken all actions necessary in connection therewith; (ii) there are no mortgages or ground leases affecting the Property and/or the
Building or any portion thereof, except the mortgage granted to Bank of America, N.A.; and (iii) the person executing this Lease on behalf of Landlord is authorized to do so. 


 

	5.2	Interruption. Except as otherwise expressly provided below in this Section 5.2, Landlord shall have no responsibilities, obligations, or liabilities for any failure or interruption of any of the
above-described services, or for any failure or inability to make any repairs or replacements, if such failure, interruption or inability arises out of or results from emergencies, breakage, accidents, strikes, repairs, inability 


  
 -21- 









	 	
to obtain supplies, labor or materials, or any other causes beyond the reasonable control of the Landlord. Without limiting the foregoing, in no event shall Landlord ever be liable to Tenant for
any lost profits, or for any indirect or consequential damages. No failure or omission on the part of the Landlord to furnish any of the services described in Section 5.1 shall be construed as an eviction of Tenant, actual or constructive, nor
entitle Tenant to an abatement or reduction of, or offset against, Rent, nor render the Landlord liable in damages, nor release Tenant from prompt fulfillment of any of its obligations and covenants under this Lease. 


Notwithstanding anything to the contrary contained in this Lease, if Tenant is unable despite its good faith commercially diligent efforts to
use the Premises for the ordinary conduct of Tenant’s business due solely to (a) an interruption of an Essential Service (as hereinafter defined) which Landlord is required to provide hereunder, or (b) Landlord’s breach of an
obligation under this Lease to perform repairs or replacements which results in Landlord’s failure to provide an Essential Service, in each case other than as a result of casualty or condemnation and subject to the provisions of
Section 11.5, and such condition continues for a period of longer than ten (10) consecutive business days after Tenant furnishes a notice to Landlord (the “Abatement Notice”) identifying the condition and Essential Service which
has been interrupted and stating that Tenant’s inability to use the Premises is solely due to such condition, provided that (i) Tenant does not actually use or occupy the Premises during such ten (10) consecutive Business Day period,
(it being understood that entry by Tenant’s employees solely to retrieve files, data, laptops and other equipment shall not be deemed occupancy hereunder), and (ii) such condition has not resulted from the negligence or misconduct of
Tenant or any Tenant Party, then Fixed Rent payable on account of the Premises shall be abated on a pro rata per diem basis for the period (the “Abatement Period”) commencing on the eleventh
(11th) Business Day after Tenant delivers the Abatement Notice to Landlord and ending on the earlier of (x) the date Tenant reoccupies the Premises, or (y) the date on which such
condition is substantially remedied. “Essential Service” shall mean the following services, but only to the extent that Landlord is required to provide such services to Tenant pursuant to the terms of this Lease and if not provided the
absence of such service shall materially and adversely affect the use of the Premises for the ordinary conduct of Tenant’s business: HVAC service; electrical service; passenger elevator service; and water and sewer service. The foregoing rent
abatement shall be the sole and exclusive remedy of Tenant on account of an interruption or lack of an Essential Service for ten (10) consecutive business days or longer after notice from Tenant as set forth in this Section 5.2, and
Landlord shall have no further liabilities or obligations to Tenant on account thereof. 
  

	5.3	Outside Services. If Tenant wishes to obtain “Outside Services” for the Premises, i.e. services in addition to, or in excess of, the services to be provided by Landlord as set forth herein, then Tenant
shall first obtain the prior written approval of Landlord (which approval shall not be unreasonably withheld) for the installation and/or utilization of such Outside Services. For purposes of this 


  
 -22- 









	 	
Lease, “Outside Services” shall include, but shall not be limited to, cleaning services, television, so-called “canned music” services, security services, and the like. In the
event Landlord approves the installation and/or utilization of such Outside Services, such installation and utilization shall be at Tenant’s sole cost, risk and expense, and Landlord shall have no obligations or liabilities in connection
therewith. 

  

	5.4	Discontinuance of Electrical Service. Notwithstanding any provision to the contrary contained in this Article 5, Landlord reserves the right to discontinue furnishing electricity to Tenant in the Premises on not
less than sixty (60) days notice to Tenant; provided, that, either (a) Landlord discontinues furnishing electricity to tenants (including Tenant) leasing an aggregate of at least 60% of the rentable area of the Building, or
(b) Landlord is required to do so by the public utility or pursuant to applicable laws, codes, regulations, or requirements. If Landlord discontinues furnishing electricity to Tenant, then this Lease shall continue in full force and effect and
shall be unaffected thereby, except that from and after the effective date of such discontinuance, Landlord shall not be obligated to furnish electricity to Tenant hereunder. If Landlord so discontinues furnishing electricity, then Tenant shall
arrange to obtain electricity directly from a utility company serving the Building. All equipment that may be required to obtain electricity of substantially the same quantity, quality and character shall be installed by Landlord at the sole cost
and expense of (a) Landlord, if Landlord voluntarily discontinues such service, or (b) Tenant, if Landlord is compelled to discontinue such service by the public utility or pursuant to applicable laws, codes, regulations, or requirements.
Landlord shall not voluntarily discontinue furnishing electricity to Tenant until Tenant is able to receive electricity directly from a utility company servicing the Building, unless the utility company is not prepared to furnish electricity to the
Premises on the date required as a result of Tenant’s delay or negligence in arranging for service or Tenant’s refusal to provide the utility company with a deposit or other security requested by the utility company, or Tenant’s
refusal to take any other action reasonably requested by the utility company. 

 ARTICLE 6 

Tenant’s Additional Covenants 
  

	6.1	Affirmative Covenants. Tenant covenants at all times during the Term and for such additional time (prior or subsequent thereto) as Tenant occupies the Premises or any part thereof: 


 

	6.1.1	Perform Obligations. To perform promptly all of the obligations of Tenant set forth in this Lease; and to pay when due the Fixed Rent, the Additional Rent, and all other charges, rates and other sums which by the
terms of this Lease are to be paid by Tenant. 

  

	6.1.2	Use. To use the Premises only for the Permitted Uses (and for no other purpose or purposes), and to obtain and maintain at all times all licenses and permits 


  
 -23- 









	 	
necessary or required therefor, at Tenant’s sole expense. Without limiting the foregoing, Tenant shall deliver to Landlord for its review, copies of all applications for all such licenses
and permits that are issued in connection with the use and occupancy of the Premises or Alterations proposed by Tenant in or to the Premises, prior to submission thereof to the applicable governmental authorities. 


 

	6.1.3	Repair and Maintenance. To maintain the Premises in first-class, good and neat order, condition and repair; to perform all routine and ordinary repairs to the Premises and to any plumbing, heating, electrical,
ventilating and air-conditioning systems located within the Premises, in order to maintain such systems in good working order, appearance and condition, in all cases reasonable use and wear thereof and damage by fire or casualty only excepted; to
keep all glass in windows and doors of the Premises (except glass in the exterior windows of the Building) whole and in good condition with glass of the same quality as that injured or broken; and to make all necessary repairs to the Premises and/or
the Property arising out of or resulting from misuse or damage by, or neglect or improper conduct of, Tenant or Tenant’s servants, employees, agents, invitees or licensees or otherwise, damage by fire or casualty excepted. All repairs and
replacements performed by Tenant shall be in quality and class equal to the original work. If Tenant fails to perform such obligations and the failure continues for thirty (30) days after delivery of prior notice to Tenant (except in the event
of an emergency when such notice may be delivered concurrently), then Landlord may elect, at the expense of Tenant, to perform all such cleaning and maintenance, and to make any such repairs or to repair any damage or injury to the Premises and/or
the Property caused by moving property of Tenant into or out of the Premises, or by the installation or removal of furniture or other property, or by misuse by, or neglect, or improper conduct of, Tenant or Tenant’s servants, employees, agents,
contractors, customers, patrons, invitees, or licensees. 

  

	6.1.4	Compliance with Law. To make all repairs, alterations, additions or replacements to the Premises required by any law, code, ordinance, order, or regulation of any public or governmental authority; to keep the
Premises equipped with all safety appliances so required; and to comply with the orders and regulations of all governmental authorities with respect to zoning, building, fire, health and other codes, regulations, ordinances or laws applicable to the
Premises, except that Tenant may defer compliance so long as the validity of any such law, ordinance, order or regulations shall be contested by Tenant in good faith and by appropriate legal proceedings, if Tenant first gives Landlord appropriate
assurance or security against any loss, cost or expense on account thereof; provided, however, that Tenant shall not be obligated to make any structural Alterations or Alterations to the building systems unless the need for such Alterations arises
out of or results from (i) the specific manner and nature of Tenant’s use or occupancy of the Premises, as distinguished from general office use, (ii) Alterations made by Tenant, or (iii) a breach by Tenant of any of the
provisions of this Lease. Without limiting the foregoing, within the Premises, and with respect to all means of access and egress to and from the Premises (including all entrances and doorways), Tenant shall be responsible for compliance with the
ADA. 


  
 -24- 









	6.1.5	Indemnification. To the maximum extent permitted by law, to indemnify and hold harmless Landlord and all Landlord Affiliates, and to exonerate, indemnify and hold harmless Landlord and all Landlord Affiliates
from and against any and all claims, actions, proceedings, judgments, obligations, liabilities, costs, expenses (including, without limitation, reasonable attorneys’ fees), and penalties (collectively, “Claims”) asserted by or on
behalf of any person, firm, corporation or public authority (i) arising out of or resulting from any injury, death, damage or loss to any person or property in or upon the Premises and/or the Property (or any part thereof), which Claims arise
out of or result from the use or occupancy of the Premises by Tenant or by any person claiming by, through or under Tenant (including, without limitation, all contractors, agents, patrons, employees, invitees, and customers of Tenant), or
(ii) arising out of or resulting from (a) any delivery to or service supplied to the Premises other than services supplied by or on behalf of Landlord, or (b) anything whatsoever done on the Premises, excepting, in each case, only to
the extent caused by the negligence or willful misconduct of Landlord, its agents, servants or employees. Without limiting the foregoing, if any action or proceeding is brought against Landlord and/or any Landlord Affiliates by reason of any such
Claim, upon notice from Landlord and at Tenant’s expense, Tenant shall resist or defend all such actions or proceedings and employ counsel therefor reasonably satisfactory to and approved in advance by Landlord, such approval not to be
unreasonably withheld, conditioned or delayed. 

  

	6.1.6	Landlord’s Right to Enter. To permit Landlord and its agents to enter into and examine the Premises at reasonable times and to make repairs to the Premises and/or the Building, and during the last fifteen
(15) months of the Term, to show the Premises and/or the Building. Landlord shall provide reasonable prior notice of such entry (which notice may be verbal), except in the event of emergencies when no such prior notice shall be required but
notice shall be provided to Tenant as soon as reasonably practicable following such entry. Tenant shall provide Landlord with copies of keys and a means of access to Tenant’s security system as may be necessary for such entry by Landlord.


  

	6.1.7	Personal Property at Tenant’s Risk. All of the furnishings, fixtures, equipment, effects and property of every kind, nature and description of Tenant and of all persons claiming by, through or under Tenant
which, during the continuance of this Lease or any occupancy of the Premises by Tenant or anyone claiming by, through or under Tenant, may be on the Premises, shall be at the sole risk and hazard of Tenant or such other person, excepting only to the
extent such damage is caused by the negligence or misconduct of Landlord. If the whole or any part of such personal property shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, steam pipes, or
other pipes, or by theft or from any other cause, then to the maximum extent permitted by law, Landlord shall have no liabilities or obligations as a result thereof and no 


  
 -25- 









	 	
part of such loss or damage is to be charged to or to be borne by Landlord, excepting only to the extent such damage is caused by the negligence or misconduct of Landlord. 


 

	6.1.8	Payment of Landlord’s Costs of Enforcement. To pay on demand all reasonable expenses (including, without limitation, reasonable attorneys’ fees) incurred from time-to-time by Landlord, in enforcing any
obligation of Tenant under this Lease, or in curing any breach or default by Tenant under this Lease. 

  

	6.1.9	Yield Up. (a) To yield up and surrender possession of the Premises to Landlord at the expiration of the Term or earlier termination of this Lease; to surrender all keys to the Premises; to remove all of its
trade fixtures and personal property from the Premises; to remove all Tenant’s Telecommunications Equipment and wires and cables installed by or on behalf of Tenant; to remove such Specialty Alterations installed in the Premises after the Date
of this Lease as Landlord may request in accordance with the provisions of this Section 6.1.9 and all Tenant’s signs wherever located; to repair all damage caused by such removal and to yield up the Premises (including all installations
and improvements made by Tenant, except for trade fixtures and such of such installations or improvements as Landlord shall request Tenant to remove), broom-clean and in the same good order and repair in which Tenant is obliged to keep and maintain
the Premises by the provisions of this Lease. Any property not so removed shall be deemed abandoned and, if Landlord so elects, deemed to be Landlord’s property, and may be retained or removed and disposed of by Landlord in such manner as
Landlord shall determine. Tenant shall reimburse Landlord for the entire cost and expense incurred by it in effecting the removal and disposition of property which was required to be removed by Tenant pursuant to this Lease, and in making any
repairs and replacements to the Premises after surrender thereof by Tenant. 

 Without limiting the foregoing, concurrent with
the review of the applicable Construction Documents in connection with a Change Order or, upon request of Tenant, concurrent with the review of other plans and specifications in connection with any Alterations, Landlord will notify Tenant as to
which of the proposed installations and improvements constitute Specialty Alterations which Tenant will be required to remove at the expiration of the Term provided that Tenant shall include the following legend in capitalized and bold type
displayed prominently on the top of the first page of Tenant’s notice delivered concurrently with such plans and specifications: “IF LANDLORD FAILS TO NOTIFY TENANT AT THE TIME LANDLORD APPROVES THESE PLANS AND SPECIFICATIONS THAT ANY
ALTERATIONS SHOWN THEREON ARE SPECIALTY ALTERATIONS (AS DEFINED IN THE LEASE), LANDLORD MAY NOT REQUIRE TENANT TO REMOVE SUCH SPECIALTY ALTERATIONS AT THE END OF THE TERM OF THE LEASE.” 

(b) If the Tenant remains in the Premises beyond the expiration of the Term or earlier termination of this Lease, such holding over shall be
without right and 

  
 -26- 








 
shall not be deemed to create any tenancy, but the Tenant shall be a tenant at sufferance only at the rent set forth in this Section 6.1.9(b) and otherwise upon the terms and conditions set
forth in this Lease. If possession of the Premises (or any part thereof) is not surrendered to Landlord on the expiration or earlier termination of this Lease, then (i) Tenant shall pay to Landlord for each month (or any portion thereof) prior
to the date on which Tenant actually surrenders possession of the Premises, a sum equal to one hundred and fifty percent (150%) of the Fixed Rent, Additional Rent, and other charges payable under this Lease as of the day immediately preceding
the date of expiration or earlier termination of this Lease, and (ii) if possession of the Premises (or any part thereof) is not surrendered to Landlord by the date which is ninety (90) days after the expiration or earlier termination of
this Lease, then Tenant also shall indemnify and hold harmless Landlord from and against all damages (direct, consequential, or indirect) arising out of or resulting from such holding over. 

 

	6.1.10	Rules and Regulations. To comply with the Rules and Regulations set forth in Exhibit E, and with all reasonable Rules and Regulations as may be adopted from time-to-time by Landlord (the “Rules and
Regulations”) and of which Tenant has received notice. Landlord agrees to enforce such Rules and Regulations in a nondiscriminatory fashion, except where differing circumstances justify different treatment; however, Landlord shall not be liable
to Tenant for the failure of any other tenant(s) of the Building to comply with such Rules and Regulations. In the event of any conflict or inconsistency between the Rules and Regulations (whether included in Exhibit E or later adopted) and
the terms and conditions of this Lease, the terms and conditions of this Lease shall govern and control. 

  

	6.1.11	Estoppel Certificates. Within not more than fifteen (15) days after request by Landlord, to execute, acknowledge and deliver to Landlord an estoppel certificate in writing in the form reasonably required by
Landlord, certifying as to all or any of the following: (i) that this Lease is unmodified and in full force and effect (or, if there have been any modifications stating such modifications), (ii) whether the Term has commenced and Fixed
Rent and Additional Rent have become payable hereunder and, if so, the dates to which they have been paid, (iii) whether or not, to Tenant’s knowledge, Landlord is in default in performance of any of the terms of this Lease, and, if so,
specifying such defaults, (iv) whether Tenant has accepted possession of the Premises, (v) whether Tenant has made any claim against Landlord under this Lease and, if so, the nature thereof and the dollar amount, if any, of such claim,
(vi) whether Tenant claims any offsets or defenses against enforcement of any of the terms of this Lease, and, if so, setting them forth in reasonable detail, and (vii) such further information with respect to Lease and/or the Premises as
Landlord may reasonably request and is customary in estoppel certificates provided to landlords, buyers and/or lenders. Any such statement delivered pursuant to this subsection 6.1.11 may be relied upon by Landlord, any prospective purchaser or
mortgagee of the Premises, or any prospective assignee of such mortgage. Tenant shall also deliver to Landlord such financial information as may be reasonably required by Landlord to be provided to any mortgagee or prospective purchaser of the
Property; provided, 


  
 -27- 









	 	
however, Landlord shall exercise good faith reasonable efforts to keep such financial information confidential and, prior to the delivery of any of Tenant’s financial information to such
prospective purchasers, mortgagees or assignees of any mortgage, require such prospective purchasers, mortgagees or assignees of any mortgage to sign a commercially reasonable confidentiality agreement with respect to such confidential information.


  

	6.1.12	Landlord’s Expenses Re Consents. To reimburse Landlord promptly upon demand for all reasonable legal fees and expenses incurred by Landlord in connection with all requests made by Tenant for consents or
approvals hereunder. 

  

	6.1.13	Outside Sales, etc. Not to (i) solicit sales, place signs, place or maintain any articles in any area of the Property outside of the Premises, or in the lobbies or on the sidewalks, corridors or other common
areas of the Building, nor (ii) receive or ship articles of any kind outside the designated loading areas for the Premises, nor (iii) permit the parking of vehicles so as to interfere with the use of any driveway, corridor, footwalk,
parking area, street or other common area of the Building. 

  

	6.1.14	Fire Extinguishers, etc. To maintain automatic, non-toxic, dry chemical fire extinguishing devices approved by the Fire Insurance Rating Organization having jurisdiction over the Premises, and if gas is used in
the Premises, suitable gas cut-off devices (manual and automatic). 

  

	6.1.15	Receipt and Delivery. To receive and deliver goods and merchandise only through the loading dock designated from time to time by Landlord, during ordinary weekday business hours (except for Saturday deliveries by
overnight courier firms such as Federal Express), and to cause all messenger and small scale deliveries to be made through the Building security desk, all in accordance with Landlord’s rules and regulations therefor. Without limitation, no
“hand trucks” shall be used in the lobby areas of the Building. 

  

	6.1.16	Security Measures. To maintain order and decorum in and around all portions of the Premises, and if auxiliary security personnel shall reasonably be required to maintain such order and decorum the same shall be
provided by and at the expense of Tenant whenever requested by Landlord. 

  

	6.2	Negative Covenants. Tenant covenants and agrees, at all times during the Term and during such additional times (prior or subsequent thereto) as Tenant occupies the Premises or any part thereof: 


 

	6.2.1	 Assignment and Subletting. (a) Not to assign, transfer, mortgage or pledge this Lease or to sublease (which term shall be deemed to
include the granting of concessions and licenses and the like) all or any part of the Premises or suffer or permit this Lease or the leasehold estate hereby created or any other rights arising under this Lease to be assigned, transferred or
encumbered, in whole or in part, whether voluntarily, involuntarily or by operation of law, or permit the occupancy of the Premises by anyone other than Tenant, without the prior written consent of




  
 -28- 









	 	
Landlord in each instance. In the event Tenant desires to assign this Lease or sublet any portion or all of the Premises, Tenant shall notify Landlord in writing of Tenant’s intent to so
assign this Lease or sublet the Premises, which notice shall be accompanied by (a) with respect to an assignment of this Lease, the date Tenant desires the assignment to be effective, and (b) with respect to a sublet of all or a part of
the Premises, (i) the material business terms on which Tenant would sublet such premises, and (ii) a description of the portion of the Premises to be sublet. Each such notice shall be deemed an offer from Tenant to Landlord whereby
Landlord shall be granted the right, at Landlord’s option, (1) to suspend this Lease with respect to such space as Tenant proposes to sublease (the “Partial Space”), upon the terms and conditions hereinafter set forth, or
(2) if the proposed transaction is an assignment of this Lease or a subletting of fifty percent (50%) or more of the rentable square footage of the Premises for a sublease term that expires later than twelve (12) months prior to the
Expiration Date, to terminate this Lease with respect to the entire Premises. Such option may be exercised by notice from Landlord to Tenant within ten (10) business days after Landlord’s receipt of Tenant’s notice. If Landlord
exercises its option to terminate this Lease as to the entire Premises, or to suspend this Lease as to a Partial Space, pursuant to the foregoing provisions, then (a) this Lease shall end and expire, or be suspended, with respect to all or a
portion of the Premises, as the case may be, on the date that such assignment or sublease was to commence (as if such date were the expiration date of the Term hereof), (b) Rent shall be apportioned, paid or refunded as of such date and
Tenant’s Percentage shall be appropriately adjusted, (c) Tenant, upon Landlord’s request, shall enter into an amendment of this Lease ratifying and confirming such termination or suspension, and setting forth any appropriate
modifications to the terms and provisions hereof, (d) Landlord shall be free to lease the Premises, or the portion thereof as to which such termination or suspension shall be effective, or any part thereof, to any person or persons, including,
without limitation, to Tenant’s prospective assignee or subtenant, and (e) if the termination is only as to a Partial Space, Tenant shall be liable for all costs and expenses of segregating the Partial Space from the remaining Premises,
and for the costs of separately demising the Partial Space from the remaining Premises. If Landlord does not elect to terminate or suspend this Lease as aforesaid, then Landlord’s consent shall not be unreasonably withheld to such assignment or
subletting, provided that the following conditions are met: 

 (i) the proposed assignee or subtenant is not then, and has not
within the twelve (12) months immediately preceding such request, been a tenant in the Building or an entity with whom Landlord is dealing or has dealt within such twelve (12) month period regarding the possibility of leasing space in the
Building; 
 (ii) Tenant is not in default under this Lease beyond any applicable grace period; 

(iii) the assignee or subtenant shall use the Premises only for the Permitted Uses; and 

(iv) the form and substance of the proposed sublease or instrument of assignment is reasonably satisfactory to Landlord. 

  
 -29- 








 Tenant shall furnish Landlord with any information reasonably requested by Landlord to enable Landlord to
determine whether the proposed assignment or subletting complies with the requirements contained herein, including, without limitation, financial statements relating to the proposed assignee or subtenant, which Landlord shall keep confidential. 

(b) Tenant shall, promptly after Landlord’s request therefor, reimburse Landlord, as Additional Rent, for all reasonable legal fees and
expenses incurred by Landlord in connection with any request by Tenant for such consent provided, however, with respect to each proposed sublease or assignment Tenant shall not be obligated to reimburse Landlord for more than $3,500.00 on account of
such costs and expenses, unless such sublease or assignment does not occur in the ordinary course of business (e.g. is in connection with a bankruptcy or reorganization of Tenant) or involves an amendment to this Lease or other additional
documentation (other than a customary Landlord’s consent to sublease or assignment agreement), or if Landlord provides unusual or extraordinary services in connection therewith. If Landlord consents thereto, no such subletting or assignment
shall in any way impair the continuing primary liability of Tenant hereunder, and no consent to any subletting or assignment in a particular instance shall be deemed to be a waiver of the obligation to obtain the prior written consent of Landlord
for any other subletting or assignment. If Tenant has not executed and delivered to Landlord an assignment or sublease within one hundred eighty (180) days after Landlord’s election not to terminate or suspend the Term hereof pursuant to
the provisions of Section 6.2.1(a) above, then Tenant shall submit an additional notice to Landlord, and Landlord shall again have the right to terminate the Term in the case of a proposed assignment or to suspend this Lease pro tanto for the
period and with respect to the space involved in the case of a proposed subletting, in accordance with the provisions of Section 6.2.1(a) as if Landlord’s prior election not to do so had not been made. 

(c) If Tenant shall enter into any assignment of this Lease or any sublease of all or any portion of the Premises, and in connection with any
such assignment or sublease Tenant receives rent or other consideration, either initially or over the term of the assignment or sublease, in excess of the Rent payable by Tenant hereunder, or in case of any sublease of part of the Premises in excess
of the Rent fairly allocable to such part of the Premises (after first deducting Tenant’s reasonable actual out-of-pocket costs for construction of improvements in connection with said sublease and the reasonable third-party fees and expenses
for brokerage, advertising, architectural, and legal services actually incurred by Tenant in connection with such assignment or sublease), amortized over the term of the assignment or sublease, then Tenant shall pay to Landlord, promptly after
receipt thereof, as Additional Rent, fifty percent (50%) of the excess of each such payment of rent or other consideration received by Tenant. Within sixty (60) days after Landlord’s consent to such assignment or sublease (or if
Landlord’s consent 

  
 -30- 








 
is not required hereunder, within such sixty (60) days after the date of such assignment or sublease), Tenant shall deliver to Landlord a complete list of Tenant’s reasonable
third-party brokerage fees, legal fees and architectural fees paid or to be paid in connection with such transaction, together with a list of all of Tenant’s personal property to be transferred to such assignee or sublessee. Tenant shall
deliver to Landlord evidence of the payment of such fees promptly after the same are paid. 
 (d) If Tenant is a corporation, the transfer by
one or more transfers, directly or indirectly, by operation of law or otherwise, of a majority of the stock of Tenant shall be deemed a voluntary assignment of this Lease; provided, however, that the provisions of this subsection (d) shall not
apply to the transfer of shares of stock of Tenant if and so long as the voting of stock of Tenant is publicly traded on a nationally recognized stock exchange. For purposes of this subsection (d) the term “transfers” shall be deemed
to include the issuance of new stock or of treasury stock which results in a majority of the stock of Tenant being held by a person or persons that do not hold a majority of the stock of Tenant on the date hereof. If Tenant is a partnership, the
transfer (by one or more transfers) of a majority interest in the partnership shall be deemed a voluntary assignment of this Lease. If Tenant is a limited liability company, trust, or any other legal entity, the transfer (by one or more transfers)
of a majority of the beneficial ownership interests in, or the right(s) to manage and/or direct the operations of, such entity, however characterized, shall be deemed a voluntary assignment of this Lease. 

(e) Any assignment or transfer, whether made with Landlord’s consent or without Landlord’s consent because Landlord’s consent is
not required pursuant to the applicable provisions of this Section 6.2.1, if and to the extent permitted hereunder, shall not be effective unless and until the assignee or transferee executes, acknowledges and delivers to Landlord an agreement
in form and substance satisfactory to Landlord whereby the assignee (A) assumes Tenant’s obligations under this Lease (including, without limitation, the obligation to continue to operate for the Permitted Use), and (B) agrees that,
notwithstanding such assignment or transfer, the provisions of this Section 6.2.1 shall be binding upon it with respect to all future assignments and transfers. 

(f) Notwithstanding the foregoing provisions, Landlord’s prior consent shall not be required for an assignment of this Lease in connection
with transactions with an entity which acquires all or substantially all of the assets of or ownership interests in Tenant, or into or with which Tenant is merged or consolidated so long as: (i) such entity shall agree with Landlord to be bound
by all of the obligations of Tenant hereunder; (ii) such assignment shall not relieve Tenant of any of its obligations hereunder; and (iii) such transfer was made for a legitimate independent business purpose and not for the purpose of
transferring this Lease. 
 (g) Notwithstanding the foregoing provisions, Landlord’s prior consent shall not be required for an
assignment of this Lease or a sublease of all or a portion of the Premises to an Affiliate of Tenant (but only for such period of time as such 

  
 -31- 








 
Person remains an Affiliate of Tenant), it being agreed that the subsequent transfer of control, or any other transaction(s) having the overall effect that such Person ceases to be such an
Affiliate of Tenant, shall be treated as if such transfer or transaction(s) were, for all purposes, an assignment of this Lease to a third party not an Affiliate of Tenant governed by the provisions of subsection (a). “Affiliate” shall
mean any entity (i) of which Tokai Pharmaceuticals, Inc. possesses, directly or indirectly, the power to direct or cause the direction of the management and policies of such entity, or (ii) of which Tokai Pharmaceuticals, Inc. owns not
less than fifty percent (50%) of the ownership interests; provided, however, the subsequent sale or transfer of stock or ownership interests having the overall effect that Tokai Pharmaceuticals, Inc. no longer holds fifty percent (50%) or
more of the ownership interests of such entity shall be treated as if such sale, transfer or other transaction(s) were for all purposes, an assignment of this Lease. Any assignee or sublessee pursuant to a transaction described in
Section 6.2.1(f) or (g) shall be a “Permitted Assignee.” 
 (h) The joint and several liability of Tenant and any
successors-in-interest of Tenant and the due performance of Tenant’s obligations under this Lease shall not be discharged, released or impaired by any agreement or stipulation made by Landlord, or any grantee or assignee of Landlord, extending
the time, or modifying any of the terms and provisions of this Lease, or by any waiver or failure of Landlord, or any grantee or assignee of Landlord, to enforce any of the terms and provisions of this Lease. The listing of any name other than that
of Tenant on the doors of the Premises, the Building directory or elsewhere shall not vest any right or interest in this Lease or in the Premises, nor be deemed to constitute Landlord’s consent to any assignment or transfer of this Lease or to
any sublease of the Premises or to the use or occupancy thereof by others. Any such listing shall constitute a privilege revocable in Landlord’s discretion by notice to Tenant. 

(i) Notwithstanding the foregoing, the prior consent of Landlord shall not be required with respect to, and the provisions of
Section 6.2.1 shall not apply to, occupancy agreements entered into by Tenant with its clients and customers (“Approved Users”) for the temporary occupancy of space within the Premises, provided that (a) Tenant does not
separately demise such space and the Approved Users utilize, in common with Tenant, common entryways to the Premises as well as shared central services, such as reception, photocopying and the like; (b) the Approved Users shall not occupy, in
the aggregate, more than 20% of the Rentable Area in the Premises; (c) the Approved Users occupy space in the Premises for the Permitted Uses and for no other purpose; and (d) if requested by Landlord, Tenant notifies Landlord, in writing,
of the identity of any such Approved Users prior to occupancy of the Premises by such Approved Users. If any Approved Users occupy any portion of the Premises as described herein, (i) the Approved Users shall comply with all provisions of this
Lease, and a default by any Approved User shall be deemed a default by Tenant under this Lease; (ii) all notices required to be provided by Landlord under this Lease shall be forwarded only to Tenant in accordance with the terms of this Lease
and in no 

  
 -32- 








 
event shall Landlord be required to send any notices to any Approved Users; (iii) in no event shall any use or occupancy of any portion of the Premises by any Approved User release or
relieve Tenant from any of its obligations under this Lease; (iv) the Approved Users shall be deemed to be contractors of Tenant for purposes of Tenant’s indemnification obligations set forth in this Lease; and (v) in no event shall
the occupancy of any portion of the Premises by Approved Users be deemed to create a landlord/tenant relationship between Landlord and such Approved Users, and, in all instances, Tenant shall be considered the sole tenant under this Lease
notwithstanding the occupancy of any portion of the Premises by the Approved Users. 
  

	6.2.2	Nuisance. Not to permit or cause any offensive odors or vibrations to be emitted from the Premises. Not to injure, deface or otherwise harm the Premises or the Property (or any part thereof), nor to commit any
nuisance; nor permit in the Premises any vending machine (except as used for the sale of merchandise to employees and guests of Tenant) or kerosene, gasoline, or inflammable or combustible or explosive fluid or chemical substance (other than limited
quantities of such materials or substances reasonably necessary for the operation or maintenance of office equipment or limited quantities of cleaning fluids and solvents required in Tenant’s normal operations in the Premises); nor permit any
cooking to such extent as requires special exhaust venting or in violation of the Rules and Regulations; nor permit the emission of any objectionable noise or odor; nor permit use of any telecommunications or other equipment which interferes with
the use and enjoyment by any other tenant of the Building of its demised premises; nor make, allow or suffer any waste; nor make any use of the Premises which is improper, offensive or contrary to any law or ordinance or which will invalidate any of
Landlord’s insurance or cause any increase above normal insurance premiums on the Building; nor conduct any auction, fire, “going out of business” or bankruptcy sales. 


 

	6.2.3	 Hazardous Wastes and Materials. Not to (i) cause or permit any Hazardous Materials to be used, handled, generated, stored or disposed of
on, under or above, or transported to or from, the Premises, and/or (ii) cause or permit any of the employees, agents, contractors, licensees, customers, or invitees of Tenant to use, handle, generate, store, or dispose of on, under, or above,
or transport to or from, any other portion of the Property (collectively, “Hazardous Materials Activities”). Nothing contained herein shall be deemed to prevent Tenant from using de minimus quantities of commercially available cleaners and
office supplies which are customarily used in the ordinary course of first-class business office operations, which cleaners and/or office supplies contain Hazardous Materials; provided that, Tenant shall use such cleaners and/or office supplies in
strict compliance (at Tenant’s sole cost and expense) with all applicable laws, and shall use all necessary and appropriate precautions to prevent any spill, discharge, release or exposure to persons or property. Landlord shall not be liable to
Tenant for any loss, cost, expense, claim, damage or liability arising out of any Hazardous Materials Activities by Tenant, or by Tenant’s employees, agents, contractors, licensees, customers or invitees, whether or not consented to by




  
 -33- 









	 	
Landlord. Tenant shall indemnify, defend with counsel acceptable to and approved by Landlord, and hold Landlord and all Landlord Affiliates harmless from and against any and all losses, costs,
expenses (including, without limitation, all reasonable attorneys fees), claims, damages, obligations and liabilities arising out of: (i) any Hazardous Materials Activities on the Premises first occurring after the Commencement Date, whether or
not consented to by Landlord; (ii) any Hazardous Materials Activities by Tenant, Tenant’s employees, agents, contractors, licensees, customers or invitees or anyone claiming by, through or under Tenant, wherever occurring; and
(iii) any contamination, claim of contamination, loss or damage, or the like arising out of or resulting from the foregoing. For purposes hereof, “Hazardous Materials” shall include but not be limited to substances defined as
“hazardous substances,” “toxic substances” or “hazardous wastes” or “oil” in any local, state or federal law, rule, regulation or ordinance (collectively, “Environmental Law(s)”). If Landlord
consents to any Hazardous Materials Activities, prior to using, storing or maintaining any Hazardous Materials on or about the Premises, Tenant shall provide Landlord with a list of the types and quantities thereof, and shall update such list from
time-to-time as necessary for continued accuracy. Tenant shall also provide Landlord with a copy of any Hazardous Materials inventory statement and any updates thereof required by any applicable Environmental Laws. If Tenant’s activities
violate or create a risk of violation of any Environmental Law or cause a spill, discharge, release or exposure to any persons or property, Tenant shall cease such activities immediately. Tenant shall immediately notify Landlord both by telephone
and in writing of any spill, discharge, release or exposure of Hazardous Materials in or about the Premises, or of any condition in or about the Premises constituting an “imminent hazard” under any Environmental Laws. Landlord,
Landlord’s representatives and employees may enter the Premises during the Term to inspect Tenant’s compliance herewith, and may disclose any spill, discharge, release, or exposure or any violation of any Environmental Laws to any
applicable governmental agencies or authorities. 

  

	6.2.4	Floor Load; Heavy Equipment. Not to place a load upon any floor of the Premises exceeding the floor load per square foot area which Landlord reasonably determines the floor is adequate to carry, and in no event,
in excess of that allowed by law. Landlord reserves the right to reasonably prescribe the weight and position of all heavy business machines and equipment, including safes, which shall be placed so as to distribute the weight. Business machines and
mechanical equipment which cause vibration or noise shall be placed and maintained by Tenant at Tenant’s expense in settings sufficient to absorb and prevent vibration, noise and annoyance. Tenant shall not move any safe, heavy machinery, heavy
equipment, freight or fixtures into or out of the Premises except in such manner and at such time as Landlord shall reasonably authorize in each instance. 

  

	6.2.5	 Improvements, Alterations and Additions. (a) Not to make any installations, improvements, alterations or additions (collectively,
“Alterations”) in, to or on the Premises, nor the installation or modification of any locks or security devices, 



  
 -34- 









	 	
without on each occasion obtaining the prior written consent of Landlord. Notwithstanding the foregoing, Landlord’s prior written consent shall not be required in connection with usual and
customary interior decorative or cosmetic Alterations that satisfy the following criteria: (i) the Alteration is of a decoration or cosmetic nature such as wallpapering, painting, carpeting or installation of artwork, (ii) the Alteration
is non-structural and does not affect the Building Systems, (iii) the Alteration affects only the Premises and is not visible from outside of the Premises or the Building, (iv) the Alteration will not adversely affect any service furnished
by Landlord to Tenant or to any other tenant of the Building, (v) the Alteration does not require work to be performed inside the walls, above the ceiling, or below the floor of the Premises, and (vi) the Alteration is in compliance with,
and does not cause any violations of, all applicable laws, codes, ordinances, by-laws, and requirements. All Alterations (excepting only decorative Alterations) shall be performed pursuant to plans and specifications approved by Landlord in advance
in each instance and by contractors approved by Landlord in its reasonable discretion. All Alterations shall be performed in a manner and fashion so as to minimize interference with the other tenants and occupants of the Building, with Landlord and
Landlord’s operations in the Building and with other labor working on the Premises and/or the Property (or any part thereof). Tenant shall pay promptly when due the entire cost and expense of all Alterations to the Premises undertaken by Tenant
and in any event shall cause the Premises at all times to be free of liens for labor and materials. All Alterations performed by Tenant shall be performed in a good and workmanlike manner, employing materials of the highest quality and in compliance
with all applicable Requirements. To the maximum extent permitted by law, Tenant shall indemnify and hold harmless Landlord and all Landlord Affiliates from (i) any personal injury, death, damage or loss to any person or property arising out of
or resulting from any Alterations undertaken by Tenant, and (ii) any liabilities and/or obligations for any and all liens or encumbrances filed against the Property or any part thereof or interest therein arising out of or resulting from the
Alterations performed by Tenant. Tenant, at its expense, shall procure the discharge or bonding of all such liens and encumbrances within thirty (30) days after the filing of any such lien or encumbrance against the Premises and/or the Property
or any part thereof. If Tenant shall fail to cause any such lien or encumbrance to be discharged or bonded within such thirty (30) day period, then, in addition to any other right or remedy, Landlord may, but shall not be obligated to,
discharge the same either by paying the amount claimed to be due or by deposit or bonding proceedings, and in any such event Landlord shall be entitled, if it elects, to compel the prosecution of an action for the foreclosure of such lien and to pay
the amount of the judgment in favor of the lien with interest, costs and allowances. Without limiting the foregoing, any amount so paid by Landlord, and all costs and expenses incurred by Landlord in connection therewith, shall constitute Additional
Rent under this Lease and shall be paid by Tenant to Landlord within ten (10) days after demand. 

 (b) Prior to
commencing any Alterations, Tenant shall, at Tenant’s sole cost and expense: (i) secure all licenses, permits and approvals required by any 

  
 -35- 








 
governmental authorities in connection therewith; (ii) deliver to Landlord a statement of the names of all of its contractors and subcontractors, and the estimated costs of all labor and
material to be furnished by them; (iii) furnish to Landlord reasonably satisfactory evidence of the insurance coverages maintained by Tenant in accordance with the requirements of Section 4.2.4 of this Lease; and (iv) cause each
contractor to carry (A) workers’ compensation insurance in statutory amounts and employer’s liability insurance with limits of not less than $500,000.00 per accident covering all the contractor’s and subcontractor’s
employees, (B) commercial general liability insurance, including completed operations coverage, for a period of not less than one (1) year beyond completion of the work that the contractor/subcontractor performs, with such limits as
Landlord may reasonably require but in no event less than $5,000,000.00 per occurrence, and (C) automobile liability insurance with such limits as Landlord may reasonably require, but in no event less than $1,000,000.00 combined single limit
per accident, with liability coverage of not less than $4,000,000.00 (for a total of $5,000,000.00 in an umbrella liability policy). All such insurance coverages (i) shall be written by companies duly licensed in the Commonwealth of
Massachusetts and reasonably approved by Landlord, (ii) shall name Landlord, all Landlord Affiliates requested by Landlord, and Tenant as additional insureds, as their respective interests may appear, as well as their respective contractors and
subcontractors, (iii) shall contain a waiver of subrogation provision in favor of Landlord and all such Landlord Affiliates, and (iv) shall provide primary coverage as to any other coverage maintained by any insured other than Tenant.
Tenant shall deliver to Landlord certificates of all such insurance before Tenant begins any Alterations. 
 (c) Landlord may inspect the
Alterations in progress at reasonable times and from time-to-time; provided, however, Landlord shall, except in case of emergency, (i) give Tenant reasonable prior notice of such inspections, and (ii) conduct such inspections so as to
minimize interference with the construction work of Tenant. 
 (d) At Landlord’s request, promptly after such Alterations are completed,
Tenant shall provide Landlord with a complete set of “as-built” plans for the portions of the Premises affected by such work, prepared using electronic CAD files in AUTO CAD format. 

(e) All Alterations shall be performed (a) in a good and first-class workmanlike manner and free from defects, (b) in accordance with
the plans and specifications approved by Landlord, and by contractors approved by Landlord, (c) if requested by Landlord, under the supervision of a licensed architect reasonably satisfactory to Landlord, and (d) in compliance with all
applicable laws, by-laws, ordinances, codes, regulations and guidelines, the terms of this Lease, and all procedures and regulations then prescribed by Landlord for coordinating all work performed in the Property. 

  
 -36- 








 (f) Tenant shall pay promptly to Landlord or its designee, upon demand, all reasonable
out-of-pocket architectural and engineering fees and costs actually incurred by Landlord in connection with the review and supervision of Tenant’s Alterations (including the Tenant’s Work), including costs incurred in connection with
Landlord’s review of the Alterations (including review of requests for approval thereof). In addition, if Tenant’s Alterations shall cost more than $100,000.00, Tenant shall pay to Landlord or its designee, upon demand, an administrative
fee in the amount of three percent (3%) of the total cost of such Alterations. 
 (g) The approval of plans or specifications, or
consent by Landlord to the making of any Alterations, does not constitute Landlord’s agreement or representation that such plans, specifications or Alterations comply with any laws, codes, ordinances, rules, guidelines or requirements. Landlord
shall have no liability to Tenant or any other party in connection with Landlord’s approval of any plans and specifications for any Alterations, or Landlord’s consent to Tenant’s performing any Alterations. 

 

	6.2.6	Abandonment. Not to abandon or vacate the Premises during the Term without continuing to pay Rent when due hereunder. 

  

	6.2.7	Signs; Building Directory. Not to install or place any signs, displays, curtains, blinds, shades, awnings, aerials, or the like, in any areas that may be visible from outside the Premises, excepting only with the
prior written approval of the Landlord in each instance. Landlord will, at Landlord’s expense, install the name of the Tenant in the Building lobby directory. Without limiting the foregoing, subject to Landlord’s approval and in accordance
with the signage standards and specifications adopted by Landlord from time-to-time, Tenant may at its sole cost and expense install identification signage on the entrance doors to the Premises and in the elevator lobby area of the floor on which
the Premises are located. 

 ARTICLE 7 

Casualty or Taking 
  

	7.1	 Termination. In the event that the Premises or the Building and/or any material part thereof, shall be taken by any public authority or for any
public use, or shall be destroyed or damaged by fire or other casualty, or by the action of any public authority, then this Lease may be terminated at the election of Landlord. Such election, which may be made notwithstanding the fact that
Landlord’s entire interest may have been divested, shall be made by the giving of notice by Landlord to Tenant within sixty (60) days after the date of the taking or casualty. In addition to Landlord’s right to terminate as provided
herein, Tenant shall have the right to terminate this Lease if either (i) more than thirty-five percent (35%) of the Rentable Area of the Premises shall be destroyed or materially damaged by fire or casualty, or (ii) a material
portion of the common areas of the Building are destroyed or materially damaged such that Tenant is deprived of reasonable access to the Premises; and as a result thereof, (a) the Premises are not, despite




  
 -37- 









	 	
Tenant’s commercially reasonable good faith efforts, usable by Tenant in the ordinary course of Tenant’s business; and (b) within not more than thirty (30) days after the date
of the casualty or damage or of the date of Landlord’s notice to Tenant of such taking, Tenant provides Landlord with written notice of its election to terminate this Lease. Subject to the terms of this Section 7.1, if Tenant timely and
properly notifies Landlord of its election to terminate this Lease, this Lease shall terminate thirty (30) days after the date such notice is received by Landlord. Notwithstanding anything to the contrary in this Article 7, if any
damage during the final 18 months of the Term renders the Premises wholly untenantable, either Landlord or Tenant may terminate this Lease by notice to the other party within 30 days after the occurrence of such damage and this Lease shall expire on
the 30th day after the date of such notice. For purposes of this paragraph, the Premises shall be deemed wholly untenantable if Tenant shall be precluded from using more than 35% of the Rentable Area of the Premises for the conduct of its business
and Tenant’s inability to so use the Premises is reasonably expected to continue for more than 90 days. 

  

	7.2	Restoration. Subject to the terms of Section 7.1, if neither Landlord nor Tenant elects to terminate this Lease, then this Lease shall continue in force and, if such taking or damage is of or to the
Premises, a just proportion of the Rent reserved, according to the nature and extent of the damages sustained by the Premises, shall be suspended or abated until the Premises, or what may remain thereof, shall be put by Landlord in proper condition
for use, which Landlord covenants to do with reasonable diligence (subject to delays which result from any cause beyond the reasonable control of Landlord) to the extent permitted by the net proceeds of insurance recovered or damages awarded for
such taking, destruction or damage and subject to zoning and building laws or ordinances then in existence. Should the net proceeds of insurance recovered or damages awarded be insufficient to cover the cost of restoring the Premises, in the
reasonable estimate of the Landlord, the Landlord may, but shall have no obligation to, supply the amount of such insufficiency and restore the Premises with all reasonable diligence or the Landlord may terminate the Lease by giving notice to the
Tenant not later than a reasonable time after the Landlord has determined the estimated net proceeds of insurance recovered or damages awarded and the estimated cost of such restoration. In case of damage or destruction, as a result of a risk which
is not covered by the Landlord’s insurance, the Landlord shall likewise be obligated to rebuild the Premises, all as aforesaid, unless the Landlord, within a reasonable time after the occurrence of such event, gives written notice to the Tenant
of the Landlord’s election to terminate this Lease. “Net proceeds of insurance recovered or damages awarded” refers to the gross amount of such insurance or damages actually received by Landlord less the reasonable expenses of
Landlord incurred in connection with the collection of the same, including without limitation, fees and expenses for legal and appraisal services. If Landlord’s restoration work has not been substantially completed within twelve
(12) months after the taking or damage, then Tenant shall have the right to terminate this Lease by giving Landlord written notice of its election to do so within thirty (30) days after the end of such twelve (12) month period, and if
Tenant timely gives such notice, this 


  
 -38- 









	 	
Lease shall terminate on the date which is thirty (30) days after the date of the giving of such notice, unless Landlord’s restoration work is substantially completed within such thirty
(30) day period, in which event such termination notice shall be null and void and this Lease shall continue in full force and effect. 

  

	7.3	Award. Irrespective of the form in which recovery may be had by law, all rights to damages or compensation for any taking of the Premises (including, without limitation, any taking of the leasehold interest of
Tenant) shall belong to Landlord in all cases. Tenant hereby grants to Landlord all of Tenant’s rights to such damages and covenants to deliver such further assignments thereof as Landlord may from time to time request. The Tenant shall be
entitled to receive and retain only such amounts as may be specifically awarded to it in any such condemnation proceedings, as a result of the taking of its trade fixtures or furniture and its leasehold improvements to the extent the Landlord’s
award is not thereby reduced and the Tenant is not otherwise reimbursed for the same by the Landlord. 

 ARTICLE 8 

Defaults 
  

	8.1	Events of Default. If any of the following occurs: 

 (a) Tenant shall default in the
payment when due of any Fixed Rent or Additional Rent, and such default shall continue for five (5) business days after notice thereof from Landlord; or 

(b) Tenant shall have previously defaulted more than twice in any twelve (12) month period in the payment when due of any Fixed Rent or
Additional Rent, Tenant subsequently defaults in the payment when due of any Fixed Rent or Additional Rent; or 
 (c) Tenant shall default in
the timely performance or observance of any other term, covenant, or condition contained in this Lease on the Tenant’s part to be performed or observed and shall fail, within thirty (30) days after notice from Landlord of such default, to
cure such default; or if such default is not reasonably susceptible of cure within thirty (30) days, if Tenant shall fail to commence to cure such default within thirty (30) days after notice of such default from Landlord or shall
thereafter fail diligently to prosecute such cure to completion or shall fail to cure such default by not later than one hundred twenty (120) days after receipt of such notice from Landlord; or 

(d) the estate of Tenant hereby created shall be taken on execution, or by other process of law; or 

(e) Tenant commences a voluntary case under Title 11 of the United States Bankruptcy Code as from time-to-time in effect, or it authorizes, by
appropriate proceedings of trustees or other governing body the commencement of such a voluntary case; or 

  
 -39- 








 (f) Tenant files an answer or other pleading admitting or failing to deny the material
allegations of a petition filed against it commencing an involuntary case under said Bankruptcy Code, or if it seeks, consents to or acquiesces in the relief therein provided, or if it fails to controvert timely the material allegations of any such
petition; or 
 (g) there is entered an order for relief in any involuntary case commenced under said Title; or 

(h) Tenant seeks relief as a debtor under any applicable law, other than said Bankruptcy Code, of any jurisdiction relating to the liquidation
or reorganization of debtors or to the modification or alteration of the rights of creditors, or by Tenant’s consent to or acquiescence in such relief; or 

(i) there is entered an order by a court of competent jurisdiction (i) finding Tenant to be bankrupt or insolvent, (ii) ordering or
approving Tenant’s liquidation, reorganization or any modification or alteration of the rights of its creditors, or (iii) assuming custody of, or appointing a receiver or other custodian for, all or a substantial part of Tenant’s
property; or 
 (j) Tenant makes an assignment for the benefit of, or enters into a composition with, its creditors, or appoints or consents
to the appointment of a receiver or other custodian for all or a substantial part of its property; or 
 (k) Tenant rejects this Lease and a
court of competent jurisdiction enters an order approving the rejection of the Lease under Title 11 of the United States Code as from time to time in effect, or under any applicable law, other than said Title 11, of any jurisdiction relating to the
liquidation or reorganization of debtors or to the modification or alteration of the rights of creditors, or by Tenant’s consent to or acquiescence in such relief; 

then and in any of said cases, in addition to all other remedies available at law or in equity, Landlord may, to the extent permitted by law,
immediately or at any time thereafter and with or without demand or notice to Tenant, enter into and upon the Premises, or any part thereof in the name of the whole, and repossess the same as of Landlord’s former estate, and expel Tenant and
those claiming by, through or under Tenant and remove its effects without being deemed guilty of any manner of trespass, and without prejudice to any remedies which might otherwise be used for arrears of Rent and preceding breach of covenant, and/or
Landlord may terminate this Lease by sending written notice thereof to Tenant and this Lease shall terminate and come to an end on the earlier to occur of (i) entry as aforesaid, or (ii) the fifth (5th) day following the sending of
such notice as fully and completely as if such date were on the date herein originally fixed for the expiration of the Term of this Lease. Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as herein
provided. To the extent permitted by law, Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws (including M.G.L. 

  
 -40- 








 
c.186, §11), in the event of Tenant being evicted or dispossessed, or in the event of Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the
covenants and conditions of this Lease. In the event of any such termination, entry or re-entry, Landlord shall have the right to remove and store Tenant’s property and that of persons claiming by, through or under Tenant at the sole risk and
expense of Tenant and, if Landlord so elects, (x) to sell such property at public auction or private sale and apply the net proceeds to the payment of all sums due to Landlord from Tenant and pay the balance, if any, to Tenant, or (y) to
dispose of such property in any manner in which Landlord shall elect, Tenant hereby agreeing to the fullest extent permitted by law that it shall have no right, title or interest in any property remaining in the Premises after such termination,
entry or re-entry. 
  

	8.2	Remedies. (a) No termination or repossession provided for in Section 8.1 shall relieve Tenant or any guarantor of the liabilities and obligations of Tenant under this Lease, all of which shall survive
any such termination or repossession. In the event of any such termination or repossession, Tenant shall pay to Landlord, at Landlord’s election, either (i) in advance, on the first day of each month, for what would have been the entire
balance of the Term (including any unexercised Extension Term), 1/12th (and a pro rata portion thereof for any fraction of a month) of the annual Fixed Rent, Additional Rent and all other amounts for which Tenant is obligated hereunder, minus, in
each case, the actual net receipts by Landlord by reason of any re-letting of the Premises (after deducting Landlord’s reasonable expenses in connection with such re-letting, including, without limitation, remodeling costs and costs of
preparing the Premises, removal, storage and repair costs and reasonable brokers’ and attorneys’ fees), or (ii) upon demand and at the option of Landlord at any time thereafter, the present value (computed at a discount rate based
upon the Prime Rate) of the amount by which the payments of Fixed Rent and Additional Rent payable for the balance of the Term would exceed the fair rental value of the Premises for the balance of the Term, determined by Landlord as of such date,
less any proceeds of any re-letting of the Premises. For purposes of this Article, if Landlord elects to require Tenant to pay damages in accordance with the immediately preceding sentence, the total amount due shall be computed by assuming that
Tenant’s Tax Excess and Tenant’s Operating Cost Excess would be, for the balance of such unexpired Term, the amount thereof respectively for the Tax Period and calendar year, respectively, in which such termination, entry or re-entry shall
occur. 

 (b) Notwithstanding the foregoing, Landlord will use reasonable efforts to re-let 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 within Landlord’s control 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 re-let the Premises free of any claim of Tenant, (ii) lease the Premises to a 

  
 -41- 








 
tenant whose proposed use, in Landlord’s reasonable judgment, will be unacceptable, (iii) re-let 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 may elect: (i) to re-let the Premises or any part or parts thereof, for a term or
terms which may at Landlord’s option be equal to or less than or exceed the period which would otherwise have constituted the balance of the Term and may grant such inducements, allowances, concessions and free rent as Landlord in its sole
discretion considers advisable or necessary to re-let the same, and/or (ii) to make such alterations, repairs and decorations to the Premises as Landlord in its sole discretion considers advisable or necessary to re-let the same, and no action
of Landlord in accordance with the foregoing or failure to re-let or to collect rent under re-letting shall operate or be construed to release or reduce Tenant’s liability as aforesaid. In connection with any such re-letting, Landlord may take
into account all relevant factors which would be considered by a sophisticated Landlord in re-letting the Premises, and Tenant hereby waives, to the extent permitted by applicable law, any obligation Landlord may have to mitigate the Tenant’s
damages; provided, however, the foregoing provisions shall not detract from Landlord’s obligations to exercise reasonable efforts to re-let the Premises as set forth in this Section 8.2(b). 

(c) Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy,
insolvency or like proceedings by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether
or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. 
  

	8.3	Remedies Cumulative. Any and all rights and remedies which Landlord may have under this Lease, and at law and equity, shall be cumulative and shall not be deemed inconsistent with each other, and any two or more
of all such rights and remedies may be exercised at the same time insofar as permitted by law. 

  

	8.4	Landlord’s Right to Cure Defaults. After the expiration of any applicable notice and cure periods and upon reasonable prior notice (except in emergencies), Landlord may, but shall not be obligated to, cure
any default by Tenant under this Lease; and whenever Landlord so elects, all costs and expenses incurred by Landlord, including reasonable attorneys’ fees, in curing such default shall be paid, as Additional Rent, by Tenant to Landlord on
demand, together with interest thereon at the Default Rate from the date of payment by Landlord to the date of payment by Tenant. 


  
 -42- 









	8.5	Effect of Waivers of Default. Any consent or permission by Landlord to any act or omission which otherwise would be a breach of any covenant or condition herein, or any waiver by Landlord of the breach of any
covenant or condition, shall not in any way be held or construed to operate so as to impair the continuing obligation of any covenant or condition herein, or otherwise, except as to the specific instance, operate to permit similar acts or omissions.


  

	8.6	No Waiver, etc. The failure of Landlord to complain of any action or omission or to seek redress for violation of, or to insist upon the strict performance of, any covenant or condition of this Lease shall not be
deemed a waiver of such violation nor 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 any payments on account of Rent with
knowledge of the breach of any covenant of this Lease shall not be deemed to have been a waiver of such breach by Landlord. No consent or waiver, express or implied, by Landlord or by Tenant to or of any breach of any agreement or duty to the other
shall be construed as a waiver or consent to or of any other breach of the same by the other or any other agreement or duty of the other. 

  

	8.7	No Accord and Satisfaction. No acceptance by Landlord of a lesser sum than the Fixed Rent, Additional Rent or any other charge then due shall be deemed to be other than on account of the earliest installment of
such Rent or charge due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent or other charge 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 installment or pursue any other remedy in this Lease provided. 


ARTICLE 9 
 Rights of
Mortgagees 
  

	9.1	Rights of Mortgagees. (a) The rights and interests of Tenant under this Lease shall be subject and subordinate to any mortgages that are now or may hereafter be placed upon the Property and/or the Building,
and to any and all advances to be made thereunder, together with all renewals, modifications, replacements and extensions thereof. Without limitation, any mortgagee shall have the right, at its option, to subordinate its mortgage to this Lease, in
whole or in part, by recording with the Registry of Deeds a unilateral written declaration to such effect. Upon entry and taking possession of the property by a mortgagee, for the purpose of foreclosure or otherwise, such Mortgagee shall have all
the rights of Landlord, and shall be liable to perform all the obligations of Landlord arising during the period of such possession, provided, however, that such Mortgagee shall have no liability for any obligations which arise prior to the date on
which it makes such entry or takes possession. No act or failure to act on the part of Landlord which would entitle Tenant under the terms of this Lease, or by law, to be relieved of Tenant’s obligations hereunder or to terminate this Lease,
shall result in a release or termination of such obligations or a termination of this Lease unless (i) Tenant 


  
 -43- 









	 	
shall have first given written notice of Landlord’s act or failure to act to first mortgagees of record, if any, and to any other mortgagees of whom Tenant has been given written notice,
specifying the act or failure to act on the part of Landlord which could or would give basis to Tenant’s rights; and (ii) such mortgagees, after receipt of such notice, have failed or refused to correct or cure the condition complained of
within a reasonable time thereafter; but nothing contained in this paragraph (c) shall be deemed to impose any obligation on any such mortgagees to correct or cure any such condition. “Reasonable time” as used above means and includes
a reasonable time to obtain possession of the Property if any such mortgagee elects to do so and a reasonable time to correct or cure the condition if such condition is determined to exist. This Section shall be self-operative and no further
instrument of subordination shall be required. In confirmation of such subordination, Tenant shall promptly execute, acknowledge and deliver any instrument that Landlord, any mortgagee or any of their respective successors in interest may reasonably
require to evidence such subordination, which instrument shall also include commercially reasonable provisions for the recognition and non-disturbance of Tenant’s estate and rights under this Lease, consistent with the terms and conditions of
the form of subordination, non-disturbance and attornment agreement attached hereto as Exhibit H. 

 Concurrently with
the delivery of this Lease, Landlord will deliver a subordination, non-disturbance and attornment agreement from Bank of America, N.A., the current holder of a mortgage on the Property, substantially in the form attached hereto as Exhibit H.
In connection with any mortgages or ground leases entered into during the Term, Landlord shall use commercially reasonable efforts to cause such mortgagee or ground lessor to execute and deliver to Tenant a subordination, non-disturbance and
attornment agreement in the form attached hereto as Exhibit H, or such form which provides Tenant with similar benefits. 
 (b) If any
mortgagee or the nominee or designee of any mortgagee shall succeed to the rights of Landlord under this Lease, whether through possession or foreclosure action or delivery of a new lease or deed, or otherwise, then at the request of such party so
succeeding to Landlord’s rights (herein called “Successor Landlord”) and upon such Successor Landlord’s written agreement to recognize and not disturb Tenant’s estate and rights under this Lease and accept Tenant’s
attornment, Tenant shall attorn to and recognize such Successor Landlord as Tenant’s landlord under this Lease and shall promptly execute and deliver any instrument that such Successor Landlord may reasonably request to evidence such
attornment. Upon such attornment, this Lease shall continue in full force and effect as a direct lease between the Successor Landlord and Tenant upon all of the terms, conditions and covenants as are set forth in this Lease, except that the
Successor Landlord shall not be (a) liable in any way to Tenant for any act or omission, neglect or default on the part of Landlord under this Lease, (b) responsible for any monies owing by or on deposit with Landlord to the credit of
Tenant, (c) subject to any counterclaim or setoff which theretofore accrued to Tenant against Landlord, (d) bound by any modification of this Lease not 

  
 -44- 








 
previously approved by such Successor Landlord (or its predecessors in interest), or by any previous prepayment of Annual Fixed Rent or Additional Rent for more than 1 month, (e) liable to
the Tenant beyond the Successor Landlord’s interest in the Property and the rents, income, receipts, revenues, issues and profits issuing from the Property, (f) responsible for the performance of any work to be done by the Landlord under
this Lease to render the Premises ready for occupancy by the Tenant, or (g) required to remove any person occupying the Premises or any part thereof, except if such person claims by, through or under the Successor Landlord. 

 

	9.2	Modifications. If any mortgagee shall require any modification(s) of this Lease, Tenant shall, at Landlord’s request, promptly execute and deliver to Landlord such instruments effecting such modification(s)
as Landlord shall require, provided that such modification(s) do not adversely affect in any material respect any of Tenant’s rights under this Lease.

Miscellaneous Provisions 
  

	11.1	Notices from One Party to the Other. All notices required or permitted hereunder shall be in writing and addressed as follows: (i) if to the Tenant and sent prior to the Commencement Date, at the Original
Notice Address of Tenant; and if sent on or after the Commencement Date, at the Premises, or such other address as Tenant shall have last designated by notice in writing to Landlord, and; (ii) if to Landlord, at the Original Notice Address of
Landlord or such other address as Landlord shall have last designated by notice in writing to Tenant. Any notice shall be sent to such address by registered or certified mail, return receipt requested, postage prepaid, or by nationally recognized
courier, charges prepaid, or by hand and shall be effective when received or when tendered delivery is refused. 

  

	11.2	Quiet Enjoyment. Landlord agrees that upon Tenant’s paying the Rent and performing and observing the agreements, conditions and other provisions on its part to be performed and observed, Tenant shall and may
peaceably and quietly have, hold and enjoy the Premises during the Term hereof without any manner of hindrance or molestation from Landlord or anyone claiming under Landlord, subject, however, to the terms of this Lease. The foregoing covenant of
quiet enjoyment is in lieu of any other covenant, express or implied. 

  

	11.3	Lease Not to be Recorded. The Tenant agrees not to record this Lease, but each party hereto agrees, on request of the other, to execute a Notice of Lease in recordable form and complying with applicable laws, and
in form and content reasonably satisfactory to both parties. In no event shall such document set forth the rental or other charges payable by the Tenant under this Lease; and any such document shall expressly state that it is executed pursuant to
the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease. 


  
 -45- 









	11.4	Limitation of Landlord’s Liability. The term “Landlord” as used in this Lease, so far as covenants or obligations to be performed by Landlord are concerned, shall be limited to mean and include
only the owner or owners at the time in question of the Property, and in the event of any transfer or transfers of title to the Property, the Landlord (and in case of any subsequent transfers or conveyances, the then grantor) shall be concurrently
freed and relieved from and after the date of such transfer or conveyance, without any further instrument or agreement, of all liability and obligation with respect to the performance of any covenants or obligations on the part of the Landlord
contained in this Lease thereafter to be performed, it being intended hereby that the covenants and obligations contained in this Lease on the part of Landlord, shall, subject as aforesaid, be binding on the Landlord, its successors and assigns,
only during and with respect to their respective successive periods of ownership of such leasehold interest or fee, as the case may be. Tenant, its successors and assigns, shall not assert nor seek to enforce any claim for breach of this Lease
against any of Landlord’s assets other than Landlord’s interest in the Property and in the rents, issues and profits thereof, and Tenant agrees to look solely to such interests for the satisfaction of any liability or claim against
Landlord under this Lease. In no event shall Landlord or any Landlord Affiliates, including, without limitation, any general or limited partner, trustees, beneficiaries, employees, agents, officers, directors, stockholders, managers, or members of
Landlord ever be personally liable for any liability or obligation of, Landlord whether under this Lease, or at law or in equity. 

  

	11.5	Acts of God. In any case where either party hereto is required to perform any work or take any action, delays caused by or resulting from Acts of God, war, civil commotion, fire, flood or other casualty, labor
difficulties, shortages of labor, materials or equipment, government regulations, unusually severe weather, or other causes beyond such party’s reasonable control (but financial inability shall never be deemed to be an event beyond either
party’s reasonable control) (each a “Force Majeure Event”) shall not be counted in determining the time during which work shall be completed or such action shall be taken, whether such time be designated by a fixed date, a fixed time
or a “reasonable time,” and such time shall be deemed to be extended by the period of such delay. Nothing contained in this Section 11.5 shall be applicable to, or in any way affect, reduce or abate the obligations of Tenant under
this Lease to pay all Rent and other charges in a timely fashion pursuant to the terms hereof. 

  

	11.6	 Landlord’s Default. Landlord shall not be deemed to be in default in the performance of any of its obligations hereunder unless it shall
fail to perform such obligations and such failure shall continue for a period of thirty (30) days or, if such obligation is incapable of being performed within thirty (30) days, such additional time as is reasonably required to correct any
such default after written notice has been given by Tenant to Landlord specifying the nature of Landlord’s 



  
 -46- 









	 	
alleged default. Notwithstanding any provision contained herein, in no event shall Landlord ever be liable to Tenant, or any person claiming by, through or under Tenant, for any special,
indirect, incidental or consequential damages, or for any lost profits. Tenant shall have no right to terminate this Lease as a result of any breach or default by Landlord hereunder, except in the case of a wrongful eviction (constructive or actual)
of the Tenant from the Premises by Landlord. In addition, Tenant shall have no right, as a result of any such breach or default, to offset or counterclaim against any Rent due hereunder. 


 

	11.7	Brokerage. Tenant warrants and represents that it has dealt with no broker in connection with the consummation of this Lease, other than the Broker, and in the event of any claims for a brokerage commission or
finder’s fee, of any kind, against Landlord predicated upon prior dealings with Tenant, Tenant agrees to defend the same and indemnify and hold Landlord harmless against any such claim. Landlord warrants and represents that it has dealt with no
broker in connection with the consummation of this Lease, other than the Brokers, and in the event of any claims for a brokerage commission or finder’s fee, of any kind, against Tenant predicated upon prior dealings with Landlord, Landlord
agrees to defend the same and indemnify and hold Tenant harmless against any such claim. Landlord shall be responsible for paying the commission due to Brokers in connection with this Lease in accordance with a separate agreement or understanding
between them. 

  

	11.8	Applicable Law and Construction. This Lease shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts. If any provisions of this Lease shall to any extent be invalid, the
remainder of this Lease shall not be affected thereby. There are no oral or written agreements between Landlord and Tenant affecting this Lease. This Lease may be amended, and the provisions hereof may be waived or modified, only by instruments in
writing executed by Landlord and Tenant. The captions and titles of the several Articles and Sections contained herein are for convenience only and shall not be considered in construing this Lease. Unless repugnant to the context, the words
“Landlord” and “Tenant” appearing in this Lease shall be construed to mean those named above and their respective heirs, executors, administrators, successors and assigns, and those claiming by, through or under them,
respectively. If there be more than one tenant, the obligations imposed by this Lease upon Tenant shall be joint and several. 

  

	11.9	Delivery. This submission of this document for examination and negotiation does not constitute an offer to lease, or a reservation of or option for, the Premises, and this Lease shall not be binding upon Landlord
or Tenant unless and until Landlord shall have executed and delivered a fully executed copy of this Lease to Tenant. 

  

	11.10	 Rent. Notwithstanding anything to the contrary contained in this Lease, all charges and amounts payable by Tenant to or on behalf of Landlord
under this Lease, whether or not expressly denominated Fixed Rent, Tax Excess, Operating 



  
 -47- 









	 	
Cost Expense, Additional Rent or Rent, shall constitute rent for the purposes of Section 502(b)(6) of the United States Bankruptcy Code. In addition, notwithstanding anything to the contrary
contained in this Lease, all charges and amounts payable by Tenant to or on behalf of Landlord under this Lease (excepting only Fixed Rent), whether or not expressly denominated Additional Rent, including, without limitation, Tax Excess, Operating
Costs Excess, electricity charges, utility charges, and other fees and charges, shall be considered to be “Additional Rent” and in the event of non-payment thereof by Tenant Landlord shall have all of the rights and remedies as would
accrue for non-payment of Fixed Rent. 

  

	11.11	Certain Interpretational Rules. For purposes of this Lease, whenever the words “include”, “includes”, or “including” are used, they shall be deemed to be followed by the words
“without limitation” and, whenever the circumstances or the context requires, the singular shall be construed as the plural, the masculine shall be construed as the feminine and/or the neuter and vice versa. This Lease shall be interpreted
and enforced without the aid of any canon, custom or rule of law requiring or suggesting construction against the party drafting or causing the drafting of the provision in question. The captions in this Lease are inserted only as a matter of
convenience and for reference and in no way define, limit or describe the scope of this Lease or the intent of any provision hereof. 

  

	11.12	Parties Bound. The terms, covenants, conditions and agreements contained in this Lease shall bind and inure to the benefit of Landlord and Tenant and, except as otherwise provided in this Lease, to their
respective legal representatives, successors, and assigns. Each term and each provision of this Lease to be performed by the Tenant shall be construed to be both a covenant and a condition. 


 

	11.13	Prevailing Party. In any action or proceeding brought by either party against the other under this Lease, if one party obtains a judgment on the merits in such action or proceeding, then prevailing party shall be
entitled to recover from the other party its reasonable professional fees for attorneys, appraisers and accountants, its reasonable investigation costs, and any other reasonable legal expenses and actual court costs incurred by the prevailing party
in such action or proceeding. 

  

	11.14	 Back-Up Generator. As an appurtenance to the Premises, Tenant shall have the right, upon Tenant’s request, to use up to 20KW of
capacity of the emergency back-up electrical generator (the “Back-Up Generator”) currently located in the Building. If Tenant so requests, then Tenant may, at its sole cost and expense, tie-into the Back-Up Generator, subject to the
reasonable rules and guidelines adopted from time to time by Landlord with respect thereto, and to all applicable laws, codes, regulations and guidelines. Any and all work and improvements to be performed by Tenant to effectuate Tenant’s tie-in
to the Back-Up Generator (such as installing conduits and connections from the Back-Up Generator to the Premises) shall be considered to be an Alteration, shall be performed in accordance with the provisions of Section 6.2.5 of this Lease, and,
unless 



  
 -48- 









	 	
approved by Landlord in connection with approval of the Construction Documents for Tenant’s Work pursuant to Section 3.3, shall be subject to Landlord’s review and prior written
approval in all respects. In the event Tenant elects to tie-into the Back-Up Generator, Tenant shall pay, as Additional Rent, within thirty (30) days after receipt of invoices therefor from Landlord, a pro rata share of the annual fuel and
maintenance charges for the Back-Up Generator, which pro rata share shall be based on a ratio, the numerator of which is Tenant’s total usage of Back-Up Generator capacity and the denominator of which is the aggregate usage of Back-Up Generator
capacity at the applicable period of time; provided, however, Tenant’s pro rata share of such annual fuel and maintenance charges for the Back-Up Generator payable hereunder shall not exceed $1,500.00 per year (the “Annual Generator Cost
Cap”); provided, however, if either (a) in the event that the public utility provider has a power outage that results in a power outage at the Building for more than six (6) hours, or (b) Tenant otherwise elects to run the
Back-Up Generator for more than six (6) consecutive hours, in which event, then the cost of fuel used for the Back-Up Generator during such outage or in excess of six (6) consecutive hours shall be excluded from the Annual Generator Cost
Cap and Tenant shall pay its pro rata share for such fuel used for the Back-Up Generator during such outage based on the ratio above. 


ARTICLE 12 
 Letter of
Credit 
  

	12.1	Letter of Credit. Concurrent with Tenant’s execution and delivery of this Lease, Tenant shall deliver to Landlord an irrevocable and unconditional standby letter of credit (the “Original Letter of
Credit”) which shall be: (i) in substantially the form attached hereto as Exhibit F, (ii) issued by a bank reasonably satisfactory to Landlord upon which presentment may be made in Boston, Massachusetts or which allows for
presentment by facsimile, (iii) in an amount equal to the Letter of Credit Amount, (iv) for a term of not less than one (1) year, (v) permit multiple drawings, (vi) be freely and fully transferable by Landlord without
payment of any fees or charges by Landlord, and (viii) otherwise in form and content satisfactory to Landlord. The Original Letter of Credit, any Additional Letters(s) of Credit, and any Substitute Letter(s) of Credit are referred to herein
collectively as the “Letter of Credit.” The Letter of Credit shall be held by Landlord as security for the performance by Tenant of its obligations under this Lease. The Letter of Credit is not an advance payment of Rent or a
limitation upon the liability of Tenant hereunder. Landlord acknowledges that Silicon Valley Bank is an acceptable issuer of the Original Letter of Credit. 

  

	12.2	 Renewal of Letter of Credit. Each Letter of Credit shall be automatically renewable for consecutive periods of one (1) year in accordance
with the second to last paragraph of the Letter of Credit Form attached hereto as Exhibit F; provided however, if the issuer of such Letter of Credit gives notice of its election not to renew such Letter of Credit, then Tenant shall
deliver to Landlord a new letter of credit (a “Substitute Letter of Credit”) satisfying the requirements of 



  
 -49- 









	 	
the Original Letter of Credit under Section 12.1 on or before the date thirty (30) days prior to the expiration of the term of the Letter of Credit then in effect. If Tenant fails
timely to deliver to Landlord a Substitute Letter of Credit in accordance with the foregoing provisions, then Landlord shall have the right, at any time thereafter, without giving any further notice to Tenant, to draw down the Letter of Credit and
to hold the proceeds thereof in a segregated account in the name of Landlord, which proceeds may be withdrawn and applied by Landlord under the same circumstances and for the same purposes as if such proceeds were a Letter of Credit. Upon any such
application of such proceeds by Landlord, Tenant shall, within thirty (30) days of written demand therefor, deliver to Landlord an Additional Letter of Credit in the amount of proceeds so applied. 


 

	12.3	Draws to Cure Defaults. If Tenant breaches or defaults in any of its obligations under this Lease beyond the expiration of any applicable grace period, then without prejudice to or limiting any other rights or
remedies of Landlord, Landlord shall have the right, at any time thereafter, to draw down from the Letter of Credit the amount necessary to cure such default. In the event of any such draw by the Landlord, within thirty (30) days of written
demand therefor, Tenant shall deliver to Landlord an additional Letter of Credit (“Additional Letter of Credit”) satisfying the requirements for the Original Letter of Credit set forth in Section 12.1, except that the amount of
such Additional Letter of Credit shall be the amount of such draw. 

  

	12.4	Draws to Pay Damages. In addition, if (i) this Lease shall have been terminated as a result of Tenant’s default under this Lease beyond the expiration of the applicable cure period, and/or
(ii) this Lease shall have been rejected in a bankruptcy or other similar proceeding, then Landlord shall have the right at any time thereafter to draw down from the Letter of Credit an amount sufficient to pay any and all damages payable by
Tenant on account of such termination or rejection, as the case may be, pursuant to Article 8 hereof. 

  

	12.5	Return of Letter of Credit at End of Term. Within thirty (30) days after the expiration of the Term, to the extent Landlord has not previously drawn upon any Letter of Credit held by Landlord, Landlord shall
return the same to Tenant provided that Tenant is not then in default of any of its obligations under this Lease.

13

13224 or any similar list or any law, order, rule or regulation or any Executive Order of the President of the United States as a terrorist, “Specially Designated National and Blocked Person”

controlled, directly or indirectly, by any person, group, entity or nation which is) acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) neither Tenant (nor any person, group, entity or nation which owns or

the Premises or the making or receiving of any contribution or funds, goods or services to or for the benefit of a Prohibited Person. In connection with the foregoing, it is expressly understood and agreed that (x) any breach by Tenant of the
foregoing representations and warranties shall be an Event of Default by Tenant under Article 8 above, and (y) the representations and warranties contained in this Article 13 shall be continuing in nature and shall survive the expiration or
earlier termination of this Lease.

A. 255 STATE STREET LLC, a Delaware limited liability company whose address is

including all buildings, improvements, structures and fixtures located thereon, “Landlord’s Premises”), as more particularly described in Schedule A. 

B. Mortgagee has made a loan to Landlord in the original principal amount of $43,000,000.00 (the “Loan”). 

C. To secure the Loan, Landlord has encumbered Landlord’s Premises by entering into that certain Mortgage, Assignment of Leases and
Rents, Security Agreement and Fixture Filing dated April 3, 2013, for the benefit of Mortgagee (as amended, increased, renewed, extended, spread, consolidated, severed, restated, or otherwise changed from time to time, the
“Mortgage”) recorded or to be recorded in the Public Records of Suffolk County, Massachusetts (the “Land Records”). 

D. Pursuant to a Lease, dated as of             , 20     (the
“Lease”); Landlord demised to Tenant a portion of Landlord’s Premises (“Tenant’s Premises”). Tenant’s Premises are commonly known as
                    . 
 E. Tenant and
Mortgagee desire to agree upon the relative priorities of their interests in Landlord’s Premises and their rights and obligations if certain events occur. 

NOW, THEREFORE, for good and sufficient consideration and intending to be legally bound hereby, Tenant and Mortgagee agree: 

1. Definitions. The following terms shall have the following meanings for purposes of this Agreement. 

1.1. “Construction-Related Obligation(s)” means any obligation of Landlord under the Lease to make, pay for,
or reimburse Tenant for any alterations, demolition, or other improvements or work at Landlord’s Premises, including Tenant’s Premises. Construction-Related Obligations shall not include: (a) reconstruction or repair following fire,
casualty or condemnation; or (b) day-to-day maintenance and repairs. 

  
 H-1 








 1.2. “Foreclosure Event” means: (a) foreclosure under the
Mortgage; (b) any other exercise by Mortgagee of rights and remedies (whether under the Mortgage or under applicable law, including bankruptcy law) as holder of the Loan and/or the Mortgage, as a result of which Successor Landlord becomes owner
of Landlord’s Premises; or (c) delivery by Landlord to Mortgagee (or its designee or nominee) of a deed or other conveyance of Landlord’s interest in Landlord’s Premises in lieu of any of the foregoing. 

1.3. “Former Landlord” means Landlord and any other party that was landlord under the Lease at any time before
the occurrence of any attornment under this Agreement. 
 1.4. “Offset Right” means any right or alleged
right of Tenant to any offset, defense (other than one arising from actual payment and performance, which payment and performance would bind a Successor Landlord pursuant to this Agreement), claim, counterclaim, reduction, deduction, or abatement
against Tenant’s payment of Rent or performance of Tenant’s other obligations under the Lease, arising (whether under the Lease or other applicable law) from Landlord’s breach or default under the Lease. 

1.5. “Rent” means any fixed rent, base rent or additional rent under the Lease. 

1.6. “Successor Landlord” means any party that becomes owner of Landlord’s Premises as the result of a
Foreclosure Event. 
 1.7. “Termination Right” means any right of Tenant to cancel or terminate the Lease or
to claim a partial or total eviction arising (whether under the Lease or under applicable law) from Landlord’s breach or default under the Lease. 

2. Subordination. The Lease, including all rights of first refusal, purchase options and other rights of purchase, shall be, and shall
at all times remain, subject and subordinate to the Mortgage, the lien imposed by the Mortgage, and all advances made under or secured by the Mortgage. 

3. Nondisturbance; Recognition; and Attornment. 

3.1. No Exercise of Mortgage Remedies Against Tenant. So long as the Lease has not been terminated on account of Tenant’s default
that has continued beyond applicable cure periods (an “Event of Default”), Mortgagee shall not name or join Tenant as a defendant in any exercise of Mortgagee’s rights and remedies arising upon a default under the Mortgage
unless applicable law requires Tenant to be made a party thereto as a condition to proceeding against Landlord or prosecuting such rights and remedies. In the latter case, Mortgagee may join Tenant as a defendant in such action only for such purpose
and not to terminate the Lease or otherwise adversely affect Tenant’s rights under the Lease or this Agreement in such action. 

  
 H-2 








 3.2. Nondisturbance and Attornment. If the Lease has not been terminated on account of an
Event of Default by Tenant, then, when Successor Landlord takes title to Landlord’s Premises: (a) Successor Landlord shall not terminate or disturb Tenant’s possession of Tenant’s Premises under the Lease, except in accordance
with the terms of the Lease and this Agreement; (b) Successor Landlord shall be bound to Tenant under all the terms and conditions of the Lease (except as provided in this Agreement); (c) Tenant shall recognize and attorn to Successor
Landlord as Tenant’s direct landlord under the Lease as affected by this Agreement; and (d) the Lease shall continue in full force and effect as a direct lease, in accordance with its terms (except as provided in this Agreement), between
Successor Landlord and Tenant. 
 3.3. Further Documentation. The provisions of this Article shall be effective and self-operative
without any need for Successor Landlord or Tenant to execute any further documents. Tenant and Successor Landlord shall, however, confirm the provisions of this Article in writing upon request by either of them. 

4. Protection of Successor Landlord. Notwithstanding anything to the contrary in the Lease or the Mortgage, Successor Landlord shall
not be liable for or bound by any of the following matters: 
 4.1. Claims Against Former Landlord. Any Offset Right
that Tenant may have against any Former Landlord relating to any event or occurrence before the date of attornment, including any claim for damages of any kind whatsoever as the result of any breach by Former Landlord that occurred before the date
of attornment. (The foregoing shall not limit either (a) Tenant’s right to exercise against Successor Landlord any Offset Right otherwise available to Tenant because of events occurring after the date of attornment, or (b) Successor
Landlord’s obligation to correct any conditions that existed as of the date of attornment and violate Successor Landlord’s obligations as landlord under the Lease.) 

4.2. Acts or Omissions of Former Landlord. Any act, omission, default, misrepresentation, or breach of warranty, of any
previous landlord (including Former Landlord) or obligations accruing prior to Successor Landlord’s actual ownership of the Property. 

4.3. Prepayments. Any payment of Rent that Tenant may have made to Former Landlord more than thirty (30) days
before the date such Rent was first due and payable under the Lease with respect to any period after the date of attornment other than, and only to the extent that, the Lease expressly required such a prepayment. 

4.4. Payment; Security Deposit. Any obligation (a) to pay Tenant any sum(s) that any Former Landlord owed to
Tenant, or (b) with respect to any security deposited with Former Landlord, unless such security was actually delivered to Mortgagee. This paragraph is not intended to apply to Landlord’s obligation to make any payment that constitutes a
Construction-Related Obligation. 

  
 H-3 








 4.5. Modification; Amendment; or Waiver. Any modification or amendment of
the Lease, or any waiver of any terms of the Lease, made without Mortgagee’s written consent. 
 4.6. Surrender;
Etc. Any consensual or negotiated surrender, cancellation, or termination of the Lease, in whole or in part, agreed upon between Landlord and Tenant, unless effected unilaterally by Tenant pursuant to the express terms of the Lease. 

4.7. Construction-Related Obligations. Any Construction-Related Obligation of Landlord under the Lease. 

4.8. Default Under Mortgage. In the event that Mortgagee notifies Tenant of a default under the Mortgage and demands
that Tenant pay its rent and all other sums due under the Lease directly to Mortgagee, Tenant shall honor such demand and pay the full amount of its rent and all other sums due under the Lease directly to Mortgagee, without offset, or as otherwise
required pursuant to such notice beginning with the payment next due after such notice of default, without inquiry as to whether a default actually exists under the Mortgage and notwithstanding any contrary instructions of or demands from Landlord.

 5. Exculpation of Successor Landlord. Notwithstanding anything to the contrary in this Agreement or the Lease, upon any attornment
pursuant to this Agreement the Lease shall be deemed to have been automatically amended to provide that Successor Landlord’s obligations and liability under the Lease shall never extend beyond Successor Landlord’s (or its successors’
or assigns’) interest, if any, in Tenant’s Premises from time to time, including insurance and condemnation proceeds, Successor Landlord’s interest in the Lease, and the proceeds from any sale or other disposition of Tenant’s
Premises by Successor Landlord (collectively, “Successor Landlord’s Interest”). Tenant shall look exclusively to Successor Landlord’s Interest (or that of its successors and assigns) for payment or discharge of any obligations of
Successor Landlord under the Lease as affected by this Agreement. If Tenant obtains any money judgment against Successor Landlord with respect to the Lease or the relationship between Successor Landlord and Tenant, then Tenant shall look solely to
Successor Landlord’s Interest (or that of its successors and assigns) to collect such judgment. Tenant shall not collect or attempt to collect any such judgment out of any other assets of Successor Landlord. In addition to any limitation of
liability set forth in this Agreement, Mortgagee and/or its successors and assigns shall under no circumstances be liable for any incidental, consequential, punitive, or exemplary damages. 

6. Mortgagee’s Right to Cure. 

6.1. Notice to Mortgagee. Notwithstanding anything to the contrary in the Lease or this Agreement, before exercising any
Termination Right or Offset Right, Tenant shall provide Mortgagee with notice of the breach or default by Landlord giving rise to same (the “Default Notice”) and, thereafter, the opportunity to cure such breach or default as provided for
below. 

  
 H-4 








 6.2. Mortgagee’s Cure Period. After Mortgagee receives a Default
Notice, Mortgagee shall have a period of thirty (30) days beyond the time available to Landlord under the Lease in which to cure the breach or default by Landlord. Mortgagee shall have no obligation to cure (and shall have no liability or
obligation for not curing) any breach or default by Landlord, except to the extent that Mortgagee agrees or undertakes otherwise in writing. 

6.3. Extended Cure Period. In addition, as to any breach or default by Landlord the cure of which requires possession
and control of Landlord’s Premises, provided only that Mortgagee undertakes to Tenant by written notice to Tenant within thirty (30) days after receipt of the Default Notice to exercise reasonable efforts to cure or cause to be cured by a
receiver such breach or default within the period permitted by this paragraph, Mortgagee’s cure period shall continue for such additional time (the “Extended Cure Period”) as Mortgagee may reasonably require to either (a) obtain
possession and control of Landlord’s Premises and thereafter cure the breach or default with reasonable diligence and continuity, or (b) obtain the appointment of a receiver and give such receiver a reasonable period of time in which to
cure the default. 
 7. Confirmation of Facts. Tenant represents to Mortgagee and to any Successor Landlord, in each case as of the
Effective Date: 
 7.1. Effectiveness of Lease. The Lease is in full force and effect, has not been modified, and
constitutes the entire agreement between Landlord and Tenant relating to Tenant’s Premises. Tenant has no interest in Landlord’s Premises except pursuant to the Lease. No unfulfilled conditions exist to Tenant’s obligations under the
Lease. 
 7.2. Rent. Tenant has not paid any Rent that is first due and payable under the Lease more than thirty
(30) days in advance. 
 7.3. No Landlord Default. To the best of Tenant’s knowledge, no breach or default
by Landlord exists and no event has occurred that, with the giving of notice, the passage of time or both, would constitute such a breach or default. 

7.4. No Tenant Default. Tenant is not in default under the Lease and has not received any uncured notice of any default
by Tenant under the Lease. 
 7.5. No Termination. Tenant has not commenced any action nor sent or received any notice
to terminate the Lease. Tenant has no presently exercisable Termination Right(s) or Offset Right(s). 
 7.6. Commencement
Date. The “Commencement Date” of the Lease was                     . 

  
 H-5 








 7.7. No Transfer. Tenant has not transferred, encumbered, mortgaged,
assigned, conveyed or otherwise disposed of the Lease or any interest therein, other than sublease(s) made in compliance with the Lease. 

7.8. Due Authorization. Tenant has full authority to enter into this Agreement, which has been duly authorized by all
necessary actions. 
 8. Tenant Covenants. Tenant shall not, without obtaining the prior written consent of Mortgagee, (a) enter
into any agreement amending, modifying, extending, restating or terminating the Lease, (b) prepay any of the rents, additional rents or other sums due under the Lease for more than one (1) month in advance of the due dates thereof,
(c) voluntarily surrender the Tenant’s Premises demised under the Lease or terminate the Lease without cause or shorten the term thereof, or (d) assign the Lease or sublet the Tenant’s Premises or any part thereof other than
pursuant to the provisions of the Lease; and any such amendment, modification, termination, prepayment, voluntary surrender, assignment or subletting, without Mortgagee’s prior consent, shall not be binding upon Mortgagee. 

9. Miscellaneous. 

9.1. Notices. All notices or other communications required or permitted under this Agreement shall be in writing and
given by certified mail (return receipt requested) or by nationally recognized overnight courier service that regularly maintains records of items delivered. Each party’s address is as set forth in the opening paragraph of this Agreement,
subject to change by notice under this paragraph. Notices shall be effective the next business day after being sent by overnight courier service, and five (5) business days after being sent by certified mail (return receipt requested). 

9.2. Successors and Assigns. This Agreement shall bind and benefit the parties, their successors and assigns, any
Successor Landlord, and its successors and assigns. If Mortgagee assigns the Mortgage, then upon delivery to Tenant of written notice thereof accompanied by the assignee’s written assumption of all obligations under this Agreement, all
liability of the assignor shall terminate. 
 9.3. Entire Agreement. This Agreement constitutes the entire agreement
between Mortgagee and Tenant regarding the subordination of the Lease to the Mortgage and the rights and obligations of Tenant and Mortgagee as to the subject matter of this Agreement. 

9.4. Interaction with Lease and with Mortgage. If this Agreement conflicts with the Lease, then this Agreement shall
govern as between the parties and any Successor Landlord, including upon any attornment pursuant to this Agreement. This Agreement supersedes, and constitutes full compliance with, any provisions in the Lease that provide for subordination of the
Lease to, or for delivery of nondisturbance agreements by the holder of, the Mortgage. Mortgagee confirms that Mortgagee has consented to Landlord’s entering into the Lease. 

  
 H-6 








 9.5. Mortgagee’s Rights and Obligations. Except as expressly provided
for in this Agreement, Mortgagee shall have no obligations to Tenant with respect to the Lease. If an attornment occurs pursuant to this Agreement, then all rights and obligations of Mortgagee under this Agreement shall terminate, without thereby
affecting in any way the rights and obligations of Successor Landlord provided for in this Agreement. 
 9.6.
Interpretation; Governing Law. The interpretation, validity and enforcement of this Agreement shall be governed by and construed under the internal laws of the Commonwealth of Massachusetts, excluding its principles of conflict of laws. 

9.7. Amendments. This Agreement may be amended, discharged or terminated, or any of its provisions waived, only by a
written instrument executed by the party to be charged. 
 9.8. Execution. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original and all of which together shall constitute one and the same instrument. 

9.9. Mortgagee’s Representation. Mortgagee represents that Mortgagee has full authority to enter into this
Agreement, and Mortgagee’s entry into this Agreement has been duly authorized by all necessary actions.
