 ARTICLE II—PREMISES AND TERM 

2.1 The Premises, Common Areas and Parking. 

(a) Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Premises. The Premises leased hereby are comprised of the
space shown on Exhibit A. The Premises extend from the top surface of the subfloor to the bottom surface of the ceiling, but do not include exterior faces of exterior walls and exterior window glass, anything beyond the interior face of
demising walls, and pipes, ducts, conduits, wires and fixtures serving other parts of the Building; provided, however, that Tenant shall have the right to use the space, if any, between the top surface of the ceiling and the bottom surface of the
floor slab of the floor above such ceiling, and to drill into the floor slab of any floor encompassed within the Premises, all for the purpose of installing ducts, cables and conduits, so long as (i) Tenant obtains the prior written consent of
Landlord (which consent shall not be unreasonably withheld or delayed); and (ii) such installation does not interfere with the Building systems and with the quiet enjoyment of other tenants in the Building. 

(b) Tenant shall have the right to use the Common Areas in common with other tenants. The Common Areas include the Building’s common
lobbies, corridors, stairways, and elevators necessary for access to the Premises, and the common walkways and driveways necessary for access to the Building, the fitness center, the cafeteria, the common toilets, corridors and elevator lobbies of
any multi-tenant floor, and the parking area for the Building. All use of the Common Areas shall be subject to the reasonable rules and regulations of Landlord generally applicable to all tenants of the
Building from time to time of which Tenant has written notice. 
 (c) The parking areas serving the Building are located on the south and
north side of Pleasant Street. Tenant shall have the right to use, free of charge, forty-eight (48) surface parking spaces on an unreserved, first-come-first-served, non-exclusive basis, of which eight
(8) spaces shall be allocated to the lower lot located on the south side of Pleasant Street (“Lower Lot”) and forty (40) spaces allocated to the upper lot located on the north side of Pleasant Street (“Upper Lot”).
Tenant acknowledges that the parking spaces shall be used solely for Tenant’s employees and visitors. The Lower Lot will be operated pursuant to a sticker program. Tenant may elect to have the stickers transferred to rotating employees or
visitors to the Building. Landlord reserves the right from time to time to implement alternative parking access programs, including, without limitation, an access card system, to operate the Lower Lot and Upper Lot and to impose reasonable,
non-discriminatory rules and regulations from time 

  
 2 

 
to time to govern the operation of all of the parking on the Property. It is understood that Landlord shall not be responsible for policing any parking areas. Tenant shall reasonably cooperate
with Landlord to assure that Tenant and its employees and visitors observe all reasonable parking regulations established by Landlord from time to time of which Tenant has written notice and to assure that Tenant and its employees and visitors do
not use more parking spaces than the number of parking spaces provided to Tenant hereunder. Landlord shall not be liable to Tenant, and this Lease shall not be affected, if any parking rights of Tenant hereunder are impaired by any law, ordinance or
other governmental regulation imposed after the Effective Date. 
 (d) Landlord reserves the right, at any time and from time to time:
(i) to change the name and street address of the Building; (ii) to grant, modify and terminate easements and other encumbrances, (iii) to make such changes, alterations, additions, improvements, repairs or replacements in or to the
Property (including the Premises but, with respect to the Premises, only for purposes of repairs, maintenance, replacements and other rights expressly reserved to Landlord herein) and the fixtures and equipment therein, as well as in or to the
street entrances and/or the Common Areas; (iv) to designate and change from time to time areas of the Property and facilities so to be used, as it may reasonably deem necessary or desirable, provided, however, in each case, that there be no
material obstruction of access to or egress from, or material interference with the Tenant’s use or enjoyment of the Premises. Landlord may at any time or from time to time construct additional improvements in all or any part of the Property,
including, without limitation, adding additional buildings or changing the location or arrangement of any improvement in or on the Property or all or any part of the Common Areas, or add or deduct any land to or from the Property, including without
limitation Lot C as shown on the plan entitled “Overall Layout Plan,” prepared by DeVellis Zrein Inc., dated June 16, 2011, last revised August 25, 2011; provided that there shall be no increase in Tenant’s obligations or
material interference with Tenant’s rights under this Lease and that the exercise of such rights does not interfere with Tenant’s use and enjoyment of the Premises. 

2.2 Term. 
 (a) Both
parties shall be bound by all the terms of this Lease as of the Effective Date. The Term shall begin on the Commencement Date, and shall continue for the length of the Term set forth in Section 1.2 unless sooner terminated as hereinafter
provided. The Commencement Date shall be the later of: 1) the Scheduled Commencement Date; or, 2) the date the Premises are Ready for Occupancy. However, if the Tenant occupies any portion of the Premises and begins conducting its business
operations therefrom, the Commencement Date shall be immediate upon such occupancy. The Premises shall be Ready for Occupancy when Landlord achieves Substantial Completion of the construction of the Leasehold Improvements in accordance with the
final plans and specifications pursuant to Section 4.1. Substantial Completion shall mean that the Tenant Improvement Work has been completed in accordance with Exhibit B, in accordance with the final plans and specifications approved by
both Landlord and Tenant so that a certificate of occupancy can be issued, subject to minor items of repair, correction, adjustment or completion set forth in a so-called “punch list” signed by Landlord and Tenant, the incompletion of
which do not and the subsequent completion of which will not, adversely affect or interfere with Tenant’s use of the Premises. Landlord will complete the punch list items within thirty (30) days after the Commencement Date. 

(b) Landlord shall use reasonable efforts to have the Premises Ready for Occupancy on the Scheduled Commencement Date. As used in this Lease,
Ready for Occupancy shall mean on the Commencement Date, Landlord shall deliver to Tenant the Premises with all base building mechanical, electrical, life safety and plumbing systems in good operating condition and repair, free and clear of all
tenants and occupants and otherwise in the condition required by this Lease. Landlord shall use good faith, commercially reasonable efforts to obtain possession of the Premises for Tenant’s occupancy. If the Premises are not Ready for Occupancy
on the Scheduled Commencement Date, Landlord shall not be subject to any liability for such failure, and such failure shall not affect the validity of this Lease, but Tenant shall not be liable for any rent until the Commencement Date. However, if
the Premises are not Ready for Occupancy because Tenant has failed to comply with Tenant’s obligations under Section 4.1 or under any work letter or construction agreement between the parties, or has otherwise delayed Landlord in
preparing the Premises or in obtaining a certificate of occupancy for the Premises, then the Commencement Date shall be the date that the Premises would have been Ready for Occupancy except for such
Tenant-caused delay, as reasonably determined by Landlord. 

  
 3 

 (c) If the Premises are not Ready for Occupancy on or before May 1, 2014, Tenant shall
receive a rent credit equal to the per diem rent multiplied by the number of days after May 1, 2014 until the date on which the Premises are Ready for Occupancy, except that the May 1, 2014 date shall be extended by the aggregate number of
days of delays caused by force majeure and Tenant-caused delay. If the Premises are not Ready for Occupancy on or before July 15, 2014 and such failure is not due to force majeure or Tenant-caused delay, Tenant may elect to terminate this Lease upon written notice to Landlord on or before July 18, 2014. 

(d) Within fifteen (15) days of the date the Commencement Date has been established, Landlord and Tenant shall confirm the Commencement
Date by mutually executing a certificate of commencement in a form to be prepared by Landlord. 
 ARTICLE III—RENT 

3.1 Base Rent. 
 (a)
Tenant shall pay the Base Rent each month in advance on the first day of each calendar month during the Term. For any partial month at the beginning or end of the Term, Tenant shall pay a proportional share of the amount that would be due for a full
month, and with respect to a partial month at the beginning of the Term, Tenant shall pay such proportional share on the Commencement Date. In addition to the Base Rent, Tenant shall pay all additional rent and rental adjustments provided herein at
the times set forth herein, or if no time for payment is specified, then payment shall be made within thirty (30) days after Tenant’s receipt of an invoice from Landlord or another billing authority. All payments shall be made to Landlord
at Landlord’s Address or such other place as Landlord may designate in writing, without prior demand and without abatement, deduction or offset except as may be specifically set forth herein. Tenant shall not pay, and Landlord shall not accept,
any rental payment more than one month in advance. All charges to be paid by Tenant hereunder, other than Base Rent, shall be considered additional rent for the purpose of this Lease, and the words “rent” or “Rent” as used in
this Lease shall mean both Base Rent and such additional rent unless the context specifically or clearly indicates that only the Base Rent is referenced. 

3.2 Adjustment for Operating Expenses and Taxes. 

(a) Tenant shall pay, as additional rent, Tenant’s Share of Operating Expenses and Taxes for the Property. For each calendar year,
Tenant’s Share of Operating Expenses shall consist of the sum of (x) the excess of total Operating Expenses for the Property for that calendar year over the Operating Expense Base multiplied by the Tenant’s Percentage and (y) a
commercially reasonable charge for the provision of services to operate the Building during periods other than 8:00 am. to 5:00 pm. on weekdays and 9:00 a.m. to 1:00 p.m. on Saturdays and to operate the Building on holidays (which are all days on
which commercial banks in Boston, Massachusetts are authorized or required by law to close) (such periods being referred to herein as “Non-Business Hours”) that are fairly allocable to the Premises,
if such services are requested by Tenant or are necessary, in Landlord’s reasonable judgment, for Tenant’s operations during Non-Business Hours. For each fiscal year, Tenant’s Share of Taxes
shall consist of the excess of total Taxes for the Property for that fiscal year over the Real Estate Tax Base multiplied by the Tenant’s Percentage. For any partial calendar year or fiscal year at the beginning or end of the Term,
Tenant’s Share of Operating Expenses and Taxes shall be adjusted proportionately for the part of the calendar year or fiscal year falling within the Term. Tenant’s Percentage may be reduced if the Property is changed or reconfigured (but
not in the event the Building is re-measured), but shall in all cases not exceed the percentage that the Rentable Square Feet in the Premises bears to the total rentable square footage in the Property, calculated on a consistent basis. In addition,
Tenant shall pay, as additional rent, one hundred percent (100%) of any increase in Taxes not otherwise billed to Tenant which may result from any alteration, addition or improvement to the Premises that is made by or on behalf of Tenant other
than the Leasehold Improvements, but only as and to the extent it is reasonably determinable from the records of the assessing authority that such increase in Taxes are based solely upon such alteration, addition or improvement. Landlord, at its
discretion, may also assess Tenant for any extraordinary item of cost or expense which may actually occur as a direct result of Tenant’s own distinct uses or activities which shall be itemized, invoiced separately, and paid by Tenant within
thirty (30) days of its receipt of the invoice 
 (b) Before each calendar and fiscal year, Landlord shall give Tenant a reasonable
estimate of the expected Operating Expenses and Taxes for the Property, and Tenant’s Share thereof, for the coming calendar year and fiscal year, respectively (excluding Landlord’s cost for services provided during Non-Business Hours), and a calculation of the estimated amount of Tenant’s Share of Expenses. Tenant shall pay one-twelfth of the estimated

  
 4 

 
amount of Tenant’s Share of Operating Expenses and Taxes with each monthly payment of Base Rent. Within one-hundred twenty (120) days after the end of each calendar and fiscal year,
Landlord shall give Tenant a statement (the “Statement”) showing the actual Operating Expenses and Taxes for that calendar year and fiscal year, respectively, a calculation of the actual amount of Tenant’s Share of Operating Expenses
and Taxes, and a summary of amounts already paid by Tenant pursuant to this Section 3.2. Such Statement shall be in line-item detail, consistently applied throughout the Term in accordance with generally accepted accounting principles
consistently applied. Any underpayment by Tenant shall be made up by cash payment to Landlord within thirty (30) days after delivery of the Statement; any overpayment shall be paid to Tenant within thirty (30) days after delivery of the
Statement or, at Landlord’s option, shall be credited against the next due Base Rent, provided that any overpayment shall be paid in cash to Tenant within thirty (30) days if the Term has ended. No delay by Landlord in providing any
Statement shall be deemed a waiver of Tenant’s obligation to pay Tenant’s Share of Operating Expenses and Taxes. 
 (c) The
following terms used in this Section 3.2(c) shall have the following meanings for purposes of this Lease: 
 (i) The
term “fiscal year” with respect to Taxes means any twelve-month period commencing on July 1st and expiring on June 30th during the term. 
 (ii) The term “Operating Expenses” means the
total necessary out-of–pocket cost of operation of the Property that under generally accepted accounting principles consistently applied would be considered normal maintenance, management and operating expenses, including, without limitation:
(i) all costs of supplies, materials, equipment, and utilities used in or related to the operation, maintenance, and repair of the Property or any part thereof (other than the cost of any electricity which is to be paid for separately by Tenant
pursuant to Section 3.3); (ii) all labor costs, including without limitation, salaries, wages, payroll and other taxes, unemployment insurance costs and employee benefits in connection with the
on-site management, operation and maintenance of the Property or any part thereof; (iii) all maintenance, management, janitorial, legal (excluding those legal costs arising out of defaults of Landlord or
other tenants in the Building), accounting, insurance, and service agreement costs related to the Property or any part thereof, including, without limitation, service contracts with independent contractors; and (iv) costs (including financing
charges) of improvements to the Property that are designed to increase safety or reduce Operating Expenses or are required to comply with legal requirements imposed after the Commencement Date of the Lease, all such improvements to be amortized on a
straight line basis with level payments of principal and interest (at an annual interest rate equal to 2% over the prime rate published as such in the Wall Street Journal) over the reasonable life of such improvements as determined in
accordance with generally accepted accounting principles. Any of the above services may be performed by Landlord or its affiliates, provided that fees for the performance of such services shall be reasonable and competitive with fees charged by
unaffiliated entities for the performance of such services in comparable buildings in the area. All Operating Expenses shall be adjusted based on the Calculation (as defined below). 

“Operating Expenses” shall not include: 

(a) Any ground rent; 

(b) Bad debt expenses and interest, principal, points and fees on debts or amortization on any mortgage or other
debt instrument encumbering the Property; 
 (c) Costs incurred by Landlord to the extent that Landlord is
reimbursed by insurance proceeds, taking awards, or is otherwise reimbursed by third-parties; 

(d) Depreciation, amortization, interest payments or capital expenditures except as expressly set forth herein;

  
 5 

 (e) Marketing costs, including lease commission, attorneys’
fees (in connection with the negotiation and preparation of letters of intent, leases, subleases and/or assignments), space planning costs, and other costs and expenses incurred in connection with lease, sublease and/or assignment negotiations and
transactions with present or prospective tenants or other occupants of the Property, and costs incurred with respect to the installation of tenant improvements; 

(f) Expenses in connection with the enforcement of Landlord’s rights against Tenant or other tenants and
occupants of the Property; 
 (g) Expenses in connection with services or other benefits that are not offered
to Tenant or for which Tenant is charged for directly; 
 (h) Salaries of executives and other personnel above
the grade of building, property or asset manager; 
 (i) Amounts paid to affiliates or subsidiaries of Landlord
for goods or services at the Property, to the extent the same exceeds the costs of such goods and/or services rendered by unaffiliated third parties on a competitive basis; 

(j) wages, salaries and benefits paid to any persons not directly involved with the management of the Building or the oversight
thereof; 
 (k) costs in the nature of penalties or fines; 

(l) the costs of installing, operating and maintaining a specialty improvement, including lodging or a private dining facility,
or an athletic (other than maintenance and operation of the Building fitness or health center), luncheon or recreational club unless Tenant is permitted to make use of such facility without additional cost or on a subsidized basis consistent with
other users, in which event only costs to the extent greater than net revenues received by Landlord from such facility shall be included; 

(m) costs incurred in connection with the survey, testing, removal, encapsulation, remediation or other treatment of asbestos
or any other Hazardous Materials at the Building or elsewhere; 
 (n) costs directly resulting from the willful misconduct of
Landlord or its agents, contractor or employees; 
 (o) costs of repairs incurred by reason of fire (other than for any
reasonable deductible) or other casualty or condemnation; and 
 (p) increased insurance premiums caused by Landlord or any
other tenant bringing any Hazardous Materials (other than normal office and building operation materials) to the Building. 

(iii) The term “Calculation” means that if the Building is less than 95% occupied in any calendar year during the
Term (including, without limitation, the Base Expense years), Operating Expenses shall be calculated as though the Building had been 95% occupied, and the result shall constitute the Operating Expenses for all purposes hereunder. In addition, if
during all or part of any calendar year, Landlord is not performing or furnishing any item or service to any portion of the Property (the cost of which, if performed or furnished by Landlord to such portion of the Property, would constitute a part
of Operating Expenses), on account of (a) such item or service not being required or desired by a tenant, or (b) any tenant obtaining or providing such item or service itself, then, Operating Expenses shall be deemed to be increased by an
amount equal to the additional costs and expenses which would reasonably have been incurred during such period by Landlord if it had performed or furnished such item or service to 100% of the Building. 

(iv) The term “Taxes” means any form of assessment, rental tax, license tax, business license fee, levy, charge, tax
or similar imposition, imposed by any authority having the power to tax, including any city, county, state or federal government, or any school, agricultural, lighting, library, drainage or other 

  
 6 

 
improvement or special assessment district, as against the Property or any part thereof or any legal or equitable interest of Landlord therein, or against Landlord by virtue of its interest
therein, and any reasonable costs incurred by Landlord in any proceeding for abatement thereof, including, without limitation, attorneys’ and consultants’ fees. The following shall not be included in “Taxes”:
(i) Landlord’s income, franchise taxes, gift, transfer, excise, capital stock, estate, inheritance or succession taxes, and assessments for off-site improvements, (ii) penalties or interest for
late payment of Taxes, and (iii) the portion of Taxes allocable to any Building capital improvements made after the Building was fully assessed as a completed and occupied unit and the Lease was signed except to the extent the additional
improvements directly benefit all tenants or at least directly benefit Tenant. Landlord shall reimburse Tenant for Tenant’s Share of any Tax abatements received by Landlord less legal, appraisal and other fees and expenses incurred by Landlord
in obtaining such abatement. 
 (v) As to any assessments payable in installments, Tenant shall only pay its Percentage of
installments allocable to the Lease Term. Landlord shall elect to pay such assessments in the maximum number of installments permitted by law. 

Provided that Tenant shall have first paid all of amounts due and payable by Tenant pursuant to this Article III and upon written notice
of Tenant within 60 days of the receipt of a final certificate (but not more than once with respect to any calendar year), Tenant may cause Landlord’s books and records to be audited with respect to operating costs applicable to the Building
for such calendar year. The audit shall be performed within 30 days of Landlord’s receipt of notice by a certified public accountant, not to be compensated on a contingent fee basis, selected by Tenant at Tenant’s sole cost and expense and
at a mutually agreeable time and place where the books and records are customarily kept by the Landlord (or property manager) in the ordinary course. During such time of audit Tenant shall pay its full share of operating expenses. If it is
determined that there are any amounts owed Tenant or Landlord as a result of said audit, such amount shall be reimbursed to the other within 30 days of said audit results. If the audit reveals an overstatement of operating costs of 5% or more,
Landlord shall reimburse Tenant for its out-of-pocket costs of the audit. Tenant shall keep the results of any such audit confidential and shall not disclose the results of such inspection nor the content of such books and records with any third
party other than Tenant’s consultants and attorneys. Failure of Tenant to provide Landlord with a written request to review such books and records in a timely manner pursuant to this Article 3 with respect to each calendar year shall be deemed
a waiver of Tenant’s rights hereunder with respect to such calendar year. 
 3.3 Tenant’s Electricity. 

With respect to electricity for heating, ventilation, air conditioning, lighting and equipment in the Premises, Tenant agrees to pay all
charges therefor. As part of the Leasehold Improvements described in Section 4.1, Landlord shall cause a submeter to be installed, at Landlord’s cost, whereupon Tenant shall pay to Landlord, as additional rent, the cost of all
electricity consumed in the Premises as shown on the submeter as and when bills are rendered by Landlord. Tenant agrees that it will not allow its demand requirements to adversely affect the Building’s electrical system. 

ARTICLE IV—CONSTRUCTION 

4.1 Leasehold Improvements by Landlord. 

(a) Prior to the delivery of the Premises to Tenant, Landlord shall cause to be designed and constructed at its own expense the improvements
(“Leasehold Improvements”) to the Premises depicted and described in the plans and specifications referenced in the attached Exhibit B. All work shall be performed in a good and workmanlike manner using building standard
materials and finishes as set forth on Exhibit B. Once installed, the Leasehold Improvements shall be part of the Premises and the sole property of Landlord. Except as set forth herein, Landlord shall have no obligation to improve the
Premises. 
 (b) Tenant may request reasonable changes to the preliminary plans provided, however, that no such changes shall require or
cause a structural change in the Building, render the Premises or the Building in violation of applicable laws, or materially change the size or configuration of the Premises. Tenant shall pay any additional costs required to implement any such
changes, including without limitation, architectural fees and construction cost 

  
 7 

 
increases (including costs of delay) plus a fee equal to five percent (5%) of such costs; Tenant shall pay Landlord for such costs as additional rent within fifteen (15) days after
written notice from Landlord of the amount due. Any requests by Tenant for changes in the final plans shall constitute an agreement by Tenant to any delay in completion of the Leasehold Improvements caused by reviewing, processing, and implementing
such changes; any such delay shall be deemed a delay caused by Tenant for purposes of calculating the Commencement Date under Section 2.2(b). 

(c) Landlord shall not be required to furnish professional interior design services to Tenant and shall not be required to pay for
professional interior design services engaged by Tenant. Further, Tenant’s interior furnishings, i.e., specification, supply and installation of furniture, furnishings, telephones, and moveable equipment, shall be the sole responsibility
of Tenant. Tenant may access the Premises prior to the date on which the Premises are Ready for Occupancy in order to install Tenant’s furniture, furnishings, telephones and movable equipment, in coordination with Landlord’s contractor.
All of the Tenant’s installation of interior furnishings and equipment shall be coordinated with any work being performed by Landlord in the Premises or elsewhere in the Building in such manner as to maintain harmonious labor relations and not
damage the Building or the Premises or interfere with Building operations. 
 (d) If Landlord’s contractor is delayed in completion of
the Leasehold Improvements as a result of Tenant-caused delays as described in Section 2.2(b) of the Lease, then Tenant shall be responsible for and shall pay to Landlord upon completion of the
Leasehold Improvements as additional rent the reasonable additional supervisory and general conditions out-of-pocket costs incurred by Landlord. 

4.2 Alterations by Tenant. 

(a) Tenant shall not make any alterations, decorations, additions, installations, substitutes or improvements (hereinafter collectively called
“Alterations”) in and to the Premises, without first obtaining Landlord’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed. No Alteration shall violate the Certificate of Occupancy for
the Premises or any applicable law, code or ordinance, or the terms of any superior lease or mortgage affecting the Property, affect the exterior appearance of the Building, adversely affect the value or structure of the Building, require excessive
removal expenses, adversely affect any other part of the Building, adversely affect the mechanical, electrical, sanitary or other service systems of the Building, or involve the installation of any materials subject to any liens or conditional sales
contracts (the “Approval Review Matters”). Tenant shall pay Landlord’s reasonable out-of-pocket costs of reviewing or inspecting any proposed Alterations. Notwithstanding anything to the contrary contained in this Lease,
Landlord’s consent shall not be required with respect to interior, non-structural Alterations costing less than $25,000.00 in each instance, provided the same do not impact any building electrical, plumbing or mechanical systems. 

(b) All work on any Alterations shall be done at reasonable times in a first-class workmanlike manner,
by contractors reasonably approved by Landlord, according to plans and specifications reasonably approved by Landlord. All work shall be done in compliance with all applicable laws, regulations, and rules of any government agency with jurisdiction,
and with all regulations of the Board of Fire Underwriters or any similar insurance body or bodies. Tenant shall be solely responsible for the effect of any Alterations on the Building’s structure and systems, whether or not Landlord has
consented to the Alterations, and shall reimburse Landlord within fifteen (15) days of demand for any costs incurred by Landlord by reason of any faulty work done by Tenant or its contractors. Upon completion of any Alterations, Tenant shall
provide Landlord with a complete set of “as-built” plans, if applicable for the Alterations in question. 

(c) Tenant shall use its best efforts to keep the Property and Tenant’s leasehold interest therein free of any liens or claims of liens
arising from acts or omissions of Tenant, or its subtenants, contractors or others claiming by, through or under Tenant, and shall discharge or bond any such liens within thirty (30) days of their filing. Before commencement of any work, upon
Landlord’s request, Tenant’s contractor shall provide any payment, performance and lien indemnity bond reasonably required by Landlord. Tenant shall provide evidence of such insurance as Landlord may reasonably require, naming Landlord as
an additional insured. Tenant shall indemnify Landlord and hold it harmless from and against any cost, claim, or liability arising from any work done by or at the direction of Tenant. All work shall be done so as to minimize interference with other
tenants and with Landlord’s operation of the Building or other construction work being done by Landlord. Landlord may post any notices it considers necessary to protect it from responsibility or liability for any Alterations, and Tenant shall
give sufficient notice to Landlord to permit such posting. 

  
 8 

 (d) All Alterations affixed to the Premises shall become part thereof and remain therein at the
end of the Term. However, if Landlord gives Tenant a notice, at the time Tenant requests Landlord’s consent to any Alteration, that such Alteration must be removed upon the expiration or earlier termination of this Lease, Tenant shall do so and
shall pay the cost of removal and any repair required by such removal. Notwithstanding anything in this Lease to the contrary, Landlord shall not require Tenant to remove (i) any Alterations, fixtures or equipment in the Premises as of the
Commencement Date, (ii) standard office fit-up or (iii) any other tenant improvements not involving materially increased demolition costs. All of Tenant’s personal property, trade fixtures, equipment, furniture, movable partitions,
and any Alterations not affixed to the Premises shall remain Tenant’s property, removable at any time. If Tenant fails to remove any such materials at the end of the Term, Landlord may do so and store them at Tenant’s expense, without
liability to Tenant, and may sell them at public or private sale and apply the proceeds to any amounts due hereunder, including costs of removal, storage and sale. 

ARTICLE V—LANDLORD’S OBLIGATIONS AND RIGHTS 

5.1 Services Furnished by Landlord. 

(a) Landlord shall furnish services, utilities, facilities and supplies equal in quality to those customarily provided by landlords in high
quality office buildings of a similar design in the general Watertown area. Such services, facilities and supplies shall include the services described in subsection 5.1(b) and 5.1(c) and Section 5.2 and the following: (i) cleaning
services for Building Common Areas and the Premises as described in Exhibit C, (ii) rubbish removal, (iii) window cleaning, (iv) restroom supplies, (v) sewer and water service to the Building’s restrooms,
(vi) landscape maintenance, (vii) snow removal for walks, driveways and parking areas, (viii) maintenance of plantings in interior Common Areas, (ix) Building security, (x) elevator service from the existing elevator, and
(xi) such other services, utilities, facilities and supplies as may be deemed necessary in Landlord’s reasonable judgment. 
 (b)
Subject to the provisions of this subsection 5.1(b), Landlord shall furnish space heating and cooling as normal seasonal changes may require to provide reasonably comfortable space temperature and ventilation for occupants of the Premises
under normal business operation. However, Tenant acknowledges that if the operation of its business in the Premises requires additional cooling, then it is solely Tenant’s responsibility to install and maintain the additional cooling equipment
following the procedures set forth in Section 4.2(b). 
 Landlord shall furnish space heating and cooling during normal business
hours of Monday through Friday from 8:00 a.m. to 5:00 p.m. and, upon Tenant’s request received prior to 2:00 p.m. on the immediately preceding business day, on Saturday from 9:00 a.m. to 1:00 p.m., without additional cost to Tenant. If Tenant
requests space heating and cooling beyond the aforementioned times, Landlord shall assess a commercially reasonable charge for the provision of such services consistent with the rates Landlord charges other tenants in the Building. If more than one
tenant directly benefits from these services then the cost shall be allocated proportionately between or among the benefiting tenants based upon the amount of time each tenant benefits and the square footage each lease. 

(c) Subject to the provisions of Section 3.3, Landlord shall provide electric power for lighting and office machine use under
normal business operation. Tenant’s use of electrical energy in the Premises shall not at any time exceed the capacity of any of the electrical conductors or equipment in or otherwise serving the Premises. In order to ensure that such capacity
is not exceeded and to avert possible adverse effect upon the Building electric service, Tenant shall not, without prior consent of Landlord in each instance (which consent shall not be unreasonably withheld or delayed), make any alteration or
addition to the electric system of the Premises. 
 (d) Landlord shall furnish, at Tenant’s expense, reasonable additional Building
operation services which are usual and customary in similar office buildings in the general Watertown area upon reasonable advance request of Tenant at reasonable and equitable rates from time to time established by Landlord; such charges, if any,
shall be considered to be additional rent. 

  
 9 

 (e) Landlord shall provide and install, at Landlord’s expense with respect to the first such
installation and at Tenant’s expense with respect to any subsequent installation, letters or numerals on the door to the Premises and in the lobby directory of the Building and on directories on the Property to identify Tenant’s name, the
name of entities affiliated with Tenant, the Building address, and letters in the lobby directory to identify a reasonable number of names of Tenant’s executives; all such letters and numerals shall be in the building standard graphics and no
others shall be used or permitted on the Premises. 
 5.2 Repairs and Maintenance. 

Landlord shall repair and maintain the Common Areas and structural portions of the Building and the basic plumbing, electrical, mechanical and
heating, ventilating and air-conditioning systems therein and life safety systems, except for damage resulting from a casualty or an eminent domain taking, which shall be governed by Article VIII.
Landlord shall make the repairs and replacements to maintain the Building in a condition comparable to other similar class office buildings in the Watertown area. Subject to Section 10.7, if any maintenance, repair or replacement is
required because of any act, omission or neglect of duty by Tenant or its agents, employees, invitees or contractors, the cost thereof shall be paid by Tenant to Landlord as additional rent within thirty (30) days after billing therefor. 

5.3 Quiet Enjoyment. 

Upon Tenant’s paying the rent and performing its other obligations after notice to Tenant and expiration of applicable grace and cure
periods, Landlord shall permit Tenant to peacefully and quietly hold and enjoy the Premises, subject to the provisions hereof. 
 5.4
Insurance. 
 Landlord shall insure the Property, including the Building and the Leasehold Improvements, against damage by fire and
standard extended coverage perils, including “all-risks” coverage, and shall carry commercial general liability insurance all in such reasonable amounts with such reasonable deductibles as would be
carried by a prudent owner of a similar building in the area. Landlord may carry any other forms of insurance as it or its mortgagee may deem advisable. Tenant shall have no right to any proceeds from such policies. Landlord shall not carry any
insurance on any of Tenant’s property, and shall not be obligated to repair or replace any of it. 
 5.5 Access to Premises.

 Landlord shall have reasonable access to the Premises to inspect Tenant’s performance hereunder and to perform any acts required of
or permitted to Landlord herein. Landlord shall at all times have a key or access card to the Premises, and Tenant shall not install any additional lock without Landlord’s consent. Any entry into the Premises by Landlord, under this section or
any other section of this Lease permitting such entry, shall be on reasonable advance notice, shall be done so as not to unreasonably interfere with Tenant’s use of the Premises, and shall be accompanied by a representative of Tenant if Tenant
so requests; provided, however, that such restrictions shall not apply to any situation that Landlord in good faith believes to be an emergency. 

Subject to reasonable security procedures that Landlord may institute from time to time to prevent unauthorized access to the Building, Tenant
shall have access to the Premises, twenty-four (24) hours per day, seven (7) days per week. 
 5.6 Right to Cease Providing
Services. 
 In connection with any repairs, alterations or additions to the Property or the Premises, or any other acts required of or
permitted to Landlord herein, Landlord may, if necessary, reduce or suspend service of the Building’s utilities and mechanical systems, or any of the other services, facilities or supplies required to be provided by Landlord hereunder, provided
that Landlord shall use best efforts to restore such services, facilities or supplies as soon as possible, and provided further that Landlord shall give Tenant advance notice of such reduction or suspension if such reduction or suspension is planned
in advance or if it is reasonably possible for Landlord to do so. 

  
 10 

 
In addition, Landlord may reduce or suspend such services, facilities or supplies in case of Force Majeure, as defined below. No such reduction or suspension permitted by this Section 5.6
shall constitute an actual or constructive eviction or disturbance of Tenant’s use or possession of the Premises, or an ejection of Tenant from the Premises, or a breach by Landlord of any of its obligations, and no such reduction or suspension
shall render Landlord liable for any damages, including but not limited to any damages, compensation or claims arising from any interruption or cessation of Tenant’s business, or entitle Tenant to be relieved from any of its obligations under
this Lease, or result in any abatement or reduction of rent, except as set forth in Section 5.7. 
 5.7 Failure to Provide
Services and Repairs. 
 Notwithstanding anything to the contrary contained in this Lease, if any essential services (such as HVAC,
electricity, water, passenger elevators if necessary for reasonable access to the Premises, etc.) supplied by Landlord are interrupted rendering a material portion of the Premises untenantable, or if a material portion of the Premises are rendered
untenantable in whole or in part as a result of actions of or a default by Landlord, a constructive eviction, contamination of the Premises, Building or Property, and such untenantability does not result from the negligence or willful misconduct of
Tenant, its employees, contractors, or agents, Tenant shall be entitled to an equitable abatement of Base Rent and additional rent beginning ten (10) days after the day on which Tenant notifies Landlord that a material portion of the Premises
are rendered untenantable in whole or in part. The abatement shall end when tenantability is restored and Tenant is able to use the entire Premises to conduct its business operations therein. During any such untenantability, Landlord shall use
commercially reasonable efforts to restore the services and render the entire Premises tenantable. Landlord shall not be in default or liable for any failure to perform any act or obligation or provide any service required hereunder unless Tenant
shall have given notice of such failure, and such failure continues for at least thirty (30) days thereafter; provided, however, that if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its
performance, then Landlord shall not be liable or in default if it commences such performance within thirty (30) days and thereafter diligently pursues such performance to completion. Tenant hereby waives any right under any law, ordinance,
regulation or judicial decision to make repairs or provide maintenance or perform any of Landlord’s other obligations hereunder at Landlord’s expense. 

ARTICLE VI—TENANT’S COVENANTS 

6.1 Repair and Yield Up. 

Tenant shall keep the Premises in the same order and condition as delivered to Tenant on the Commencement Date, reasonable wear and tear, and
damage by fire, other casualty, and/or taking excepted, and subject to Section 10.7, shall promptly repair any damage to the Premises or the rest of the Property caused by the negligence or willful misconduct of Tenant or its agents,
employees, or invitees, licensees or independent contractors. Landlord may require such repair to be done by a contractor reasonably designated by Landlord at Tenant’s cost, provided that costs to be charged to Tenant are reasonable and
competitive. At the end of the Term, Tenant shall peaceably yield up the Premises in the same order, repair and condition, as it is required to maintain during the Lease Term, reasonable wear and tear, and damage by fire, other casualty, and/or
taking excepted. Tenant shall remove its own property and (if required by Landlord, which requirement Landlord shall notify Tenant of at the time Landlord consents to any proposed Alterations by Tenant) any Alterations, repairing any damage caused
by such removal and restoring the Premises and leaving them clean and neat. Nothing herein shall require Tenant to remove the Leasehold Improvements. Tenant shall not cut Tenant’s telecommunications cables and wiring or remove Tenant’s
telecommunication patch panel and shall label all telephone and data cable terminals accordingly. 
 6.2 Use. 

(a) Tenant shall use the Premises only for the Permitted Uses, and shall not use or permit the Premises to be used for any other purpose.
Tenant shall not use or occupy the Premises in violation of: (i) any recorded covenants, conditions and restrictions affecting the Property of which Tenant has been given written notice by Landlord (Landlord hereby representing that there are
no such covenants, conditions or restrictions currently on record which will affect Tenant’s use of the Premises for the Permitted Uses), provided that such covenants, conditions and restrictions do not increase Tenant’s obligations or
decrease Tenant’s rights under this Lease, (ii) any 

  
 11 

 
law or ordinance or any Certificate of Occupancy issued for the Building or the Premises, or (iii) any reasonable Rules and Regulations of uniform application of which Tenant has notice
issued by Landlord for the Building and attached hereto as Exhibit D. In the event of any conflict between the Rules and Regulations and this Lease this Lease shall control. Tenant shall comply with any directive of any governmental authority
with respect to Tenant’s particular manner of use or occupancy of the Premises (as opposed to general office uses or the common areas for which Landlord shall be responsible). Tenant shall not do or permit anything in or about the Premises
which will in any way damage the Premises, obstruct or interfere with the rights of other tenants or occupants of the Building, or injure them, or use the Premises or allow them to be used for any unlawful purpose. Tenant shall not cause, maintain
or permit any nuisance in, on or about the Premises, or commit or allow any waste in or upon the Premises. Notwithstanding anything to the contrary contained in this Lease, Tenant shall not be responsible for ensuring the Premises complies with law
when (i) a notice of violation or order was issued prior to the date Tenant is given possession of the Premises or (ii) such legal requirements require investigating, certifying, monitoring, encapsulating, removing or in any way dealing
with asbestos or hazardous substances unless such asbestos or hazardous substances were introduced into the Premises by Tenant. 
 (b)
Tenant shall not obstruct any of the Common Areas or any portion of the Property outside the Premises, and shall not place or permit any signs (other than those permitted under Section 5.1(e)), curtains, blinds, shades, awnings, aerials
or flagpoles, or the like, visible from outside the Premises. 
 (c) Tenant shall keep the Premises equipped with all safety appliances
required by law because of any particular manner of use made by Tenant other than office use with customary office equipment, and shall procure all licenses and permits required because of such use. This provision shall not broaden the Permitted
Uses. 
 (d) Tenant shall not place a load upon the floor of the Premises exceeding 100 pounds per square foot. Partitions shall be
considered as part of the load. Landlord may reasonably prescribe the weight and position of all safes, files and heavy equipment that Tenant desires to place in the Premises, so as properly to distribute their weight. Tenant’s business
machines and mechanical equipment shall be installed and maintained so as not to transmit noise or vibration to the Building structure or to any other space in the Building. Tenant shall be responsible for the cost of all structural engineering
required to determine structural load and all acoustical engineering required to address any noise or vibration caused by Tenant. 
 (e)
Tenant shall not have vending machines on the Property without the prior written consent of Landlord. 
 (f) Tenant shall not keep or use
any article in the Premises, or permit any activity therein, which is prohibited by a standard insurance policy covering buildings and improvements similar to the Building and Leasehold Improvements, or would result in an increase in the premiums
thereunder unless Tenant pays for such increase. In determining whether increased premiums are a result of Tenant’s activity, a schedule issued by the organization computing the insurance rate on the Building or the Leasehold Improvements,
showing the various components of the rate, shall be conclusive evidence. Tenant shall promptly comply with all reasonable requirements of the insurance authority or of any insurer relating to the Premises. If the use or occupation of the Premises
by Tenant or by anyone Tenant allows on the Premises causes or threatens cancellation or reduction of any insurance carried by Landlord, Tenant shall remedy the condition immediately upon notice thereof. Upon Tenant’s failure to do so, Landlord
may, in addition to any other remedy it has under this Lease but subject to the provisions of Section 5.5, enter the Premises and remedy the condition, at Tenant’s cost, which Tenant shall promptly pay as additional rent. Landlord
shall not be liable for any damage or injury caused as a result of such an entry, and shall not waive its rights to declare a default because of Tenant’s failure. 

6.3 Assignment; Sublease. 

(a) Tenant shall not assign, mortgage, pledge or otherwise transfer this Lease or make any sublease of the Premises, or permit occupancy of
any part thereof by anyone other than Tenant (any such act being referred to herein as a “Transfer” and the other party with whom Tenant undertakes such act being referred to herein as a “Transferee”) without the
prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed, subject to the other provisions of this Section 6.3. Any Transfer or attempted Transfer not in compliance with all of the terms and
conditions set forth in this Section 6.3 shall be void, and shall be a default under this Lease. 

  
 12 

 (b) Any request by Tenant for Landlord’s consent to a Transfer shall include the name of the
proposed Transferee, the nature of its business and proposed use of the Premises, reasonable information as to its financial condition, and the terms and conditions of the proposed Transfer. Tenant shall supply such additional information about the
proposed Transfer and Transferee as the Landlord reasonably requests. It shall be reasonable for Landlord to refuse consent to any Transfer to any governmental agency, or to any other Transferee who by reputation or expected use is not comparable to
other types of tenants in the Building, or to any transferee whose financial strength is not at least equivalent to that of Tenant at the time of the Transfer, or to any Transferee that is an existing tenant in the Building or a prospective tenant
with whom Landlord has been in discussions in the preceding six (6) months. 
 (c) Any Transfer shall specifically make applicable to
the Transferee all of the provisions of this Section so that Landlord shall have against the Transferee all rights with respect to any further Transfer which are set forth herein. No Transfer shall affect the continuing primary liability of Tenant
(which shall be joint and several with Transferee). Consent to a Transfer in a specific instance shall not be deemed consent to any subsequent Transfer or a waiver of the requirement of consent to any future Transfer. No assignment shall be binding
upon Landlord or any of Landlord’s mortgagees, unless Tenant shall deliver to Landlord a recordable instrument containing a covenant of assumption by the Transferee running to Landlord and all persons claiming by, through or under Landlord. The
Transferee’s failure to execute such instrument shall not, however, release or discharge Transferee from its liability as a Transferee hereunder. Tenant shall not enter into any Transfer that provides for rental or other payment based on the
net income or profits derived from the Premises. With respect to any Transfer, Landlord shall be entitled to receive fifty percent (50%) of all “Bonus Rent,” which Bonus Rent shall be payable by Tenant to Landlord on a monthly basis.
For purposes of this Lease, Bonus Rent shall mean all amounts received by Tenant in excess of the Base Rent and additional rent reserved in this Lease and applicable to the space Transferred for the period of the Transfer, minus Tenant’s
reasonable expenses in connection with such Transfer for brokerage commissions, legal fees, advertising expenses, improvement allowances, free rent, Alterations and other rental concessions for the benefit of the Transferee. 

(d) Notwithstanding any contrary provision of this Section 6.3, in connection with any intent to Transfer, Landlord shall have an
option to cancel and terminate this Lease if the request is to assign the Lease or to sublet all of the Premises; or, if the request is to sublet a portion of the Premises only, to cancel and terminate this Lease with respect to such portion for the
proposed term of such sublease or for the balance of the Term if, within fifteen (15) days after Landlord receives written notice from Tenant that Tenant intends to make space available for a Transfer, Landlord notifies Tenant that it has
elected to exercise such option. Landlord may exercise said option in writing within fifteen (15) days after Landlord’s receipt from Tenant of such request, and in each case such cancellation or termination shall occur as of the date set
forth in Landlord’s notice of exercise of such option, which shall not be less than sixty (60) days nor more than one hundred twenty (120) days following the giving of such notice. If Landlord exercises Landlord’s option to
cancel this Lease or any portion thereof, Tenant shall surrender possession of the Premises, or the portion thereof which is the subject of the option, as the case may be, on the date set forth in such notice in accordance with the provisions of
this Lease relating to surrender of the Premises at the expiration of the Term. If this Lease is cancelled as to a portion of the Premises only, Base Rent after the date of cancellation shall be abated on a pro rata basis, and Tenant’s
Percentage. If Landlord does not exercise Landlord’s option to cancel this Lease or any portion thereof pursuant to the foregoing provisions, Landlord’s consent to a Transfer shall continue to be required in accordance with the other
provisions of this Section 6.3. 
 (e) Any agreement by which Tenant agrees to enter into or execute any Transfer at the direction of
any other party, or assigns its rights in the income arising from any Transfer to any other party, shall itself constitute a Transfer hereunder. If Tenant is a corporation, partnership, or other business organization, the transfer of ownership
interests, whether in one transaction or a series, forming a majority of the equity interests in Tenant, shall constitute a Transfer, unless Tenant is a corporation whose stock is traded on an exchange or over the counter. 

(f) Notwithstanding any contrary provision of this Lease, Tenant shall have no right to assign this Lease or sublet all or any portion of the
Premises and any such assignment or sublease shall be void unless on (i) the date on which Tenant notifies Landlord of its intention to enter into any assignment or sublease or (ii) the date on which such assignment or sublease is to take
effect, Tenant is not in default of any of its obligations under this Lease after notice to Tenant and expiration of applicable grace and cure periods. 

  
 13 

 (g) Notwithstanding anything to the contrary contained in this Lease, Tenant may assign this
Lease or sublet all or a portion of the Premises without Landlord’s consent, any right of recapture by Landlord or any sharing of any consideration with Landlord to an entity into or with which Tenant is merged or consolidated or to which
substantially all of Tenant’s assets or stock or membership interests are transferred or to any entity which controls, is controlled by or is under common control with Tenant. 

6.4 Indemnity; Assumption of Risk. 

(a) Tenant, at its expense, shall defend (with counsel satisfactory to Landlord), indemnify and hold harmless Landlord and its agents,
employees, invitees, licensees and contractors from and against any cost, claim, action, liability or damage of any kind arising from any bodily injury, death or property damage to the extent arising from (i) Tenant’s use and occupancy of
the Premises or any activity done or permitted by Tenant in, on, or about the Premises, (ii) the destruction of or damage to Tenant’s personal property, (iii) any Event of Default by Tenant of its obligations under this Lease, or
(iv) any negligent, tortious or illegal act or omission or willful misconduct of Tenant, its agents, employees, invitees, licensees or contractors, provided that such cost, claim, action, liability or damage is not caused by the negligence or
willful misconduct of Landlord or its agents, employees, invitees, licensees and contractors (except as otherwise provided in the last sentence of subsection 6.5(a)). 

(b) As a material consideration to Landlord for executing this Lease, Tenant assumes all risk of damage or injury to any person or property
in, on, or about the Premises from any cause including, without limitation, injury or damage which may be sustained by the person or property of Tenant, its employees, invitees, or any other person in or about the Premises, caused by or resulting
from fire, steam, electricity, gas, water or rain which may leak or flow from or into any part of the Premises, or from the breakage, leakage, obstruction, or other defects of pipes, sprinklers, wires, appliances, plumbing, air-conditioning or lighting fixtures, whether such damage or injury results from conditions arising upon the Premises, any other portion of the Property, or other sources, provided that such damage or injury is not
caused by the negligence or willful misconduct of Landlord or its agents, employees, invitees, licensees and contractors (except as otherwise provided in the last sentence of subsection 6.5(a)). Landlord shall not be liable to Tenant or any
other person or entity for any damages arising from any act or omission of any other tenant of the Building. 
 6.5 Tenant’s
Insurance. 
 (a) Tenant shall maintain the following insurance at its own expense throughout the Term: (i) Property insurance
including standard fire and extended coverage insurance, vandalism and malicious mischief endorsements, and “all-risks” coverage upon all property owned by Tenant and located in the Building, in the
full replacement cost thereof; (ii) Commercial General Liability Insurance against any liability arising out of the use, occupancy or maintenance of the Premises or the Property, which insurance may be by a blanket insurance policy and shall
provide the following coverages and endorsements: personal injury, broad form property damage, automobile (by separate policy, if necessary), premises/operations, additional insured landlord endorsement and broad form contractual liability, in
limits not less than One Million Dollars ($1,000,000.00) per occurrence and Three Million Dollars ($3,000,000) in the aggregate, with a deductible not to exceed Ten Thousand Dollars ($10,000.00); (iii) any other forms of insurance as Landlord
may reasonably require from time to time in form, in amounts and for insurance risks against which a prudent tenant would protect itself in similar facilities in the general area of the Premises. Tenant acknowledges and agrees that such property
owned by Tenant shall be at the sole risk and hazard of Tenant, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, steam pipes, or other pipes, by theft or
from any other cause, no part of said loss or damage is to be charged to or be borne by Landlord regardless of any fault of Landlord. 
 (b)
All policies shall (i) be taken out with insurers reasonably acceptable to Landlord, in form reasonably satisfactory to Landlord, (ii) include Landlord and any mortgagee of Landlord as additional insureds, as their interests may appear,
and (iii) contain a provision that any coverage afforded thereby shall be primary and noncontributing with respect to any insurance carried by Landlord, and any insurance carried by Landlord shall be excess and
non-contributing. Landlord may upon thirty (30) days’ notice to Tenant require an increase of the limits of the policies carried by Tenant if Landlord reasonably deems such limits to be inadequate
when compared to the then existing customary insurance practice in the area. Tenant shall provide certificates of insurance in form reasonably satisfactory to Landlord before the Commencement Date, and shall provide certificates evidencing

  
 14 

 
renewal at least ten (10) days before the expiration of any such policy. All policies shall contain an endorsement requiring at least thirty (30) days’ prior written notice to
Landlord and any mortgagee of Landlord prior to any material change, reduction, cancellation or other termination. 
 (c) Upon termination
of this Lease pursuant to any casualty, Tenant shall retain any proceeds attributable to Tenant’s personal property, trade fixtures, movable partitions, equipment and Alterations not affixed to the Premises, but Tenant shall immediately pay to
Landlord any insurance proceeds received by Tenant relating to any Alterations affixed to the Premises unless Landlord has required their removal, which removal requirement Landlord shall convey to Tenant when Tenant requests Landlord’s consent
to such Alterations. 
 6.6 Right of Entry. 

Subject to the provisions of Section 5.5 hereof, Tenant shall permit Landlord and its agents to examine the Premises at reasonable
times and to make any repairs or replacements Landlord deems reasonably necessary; to remove, at Tenant’s expense, after reasonable written notice to Tenant (except in the case of an emergency in which no notice shall be required), any
Alterations, signs, curtains, blinds or the like not consented to by Landlord; and to show the Premises to prospective tenants during the last nine (9) months of the Term and to prospective purchasers and mortgagees at all times. 

6.7 Payment of Taxes. 

Tenant shall pay before delinquency all taxes levied against Tenant’s personal property or trade fixtures in the Premises and any
Alterations installed by or on behalf of Tenant. If any such taxes are levied against Landlord or its property, or if the assessed value of the Premises is increased by the inclusion of a value placed on Tenant’s property, Landlord may pay such
taxes, and Tenant shall upon demand repay to Landlord the portion of such taxes resulting from such increase. Tenant may bring suit against the taxing authority to recover the amount of any such taxes, and Landlord shall cooperate therein. The
records of the City Assessor shall determine the assessed valuation, if available and sufficiently detailed. If not so available or detailed, the actual cost of construction shall be used. 

6.8 Environmental Compliance. 

Tenant shall not cause any hazardous or toxic wastes, hazardous or toxic substances or hazardous or toxic materials (collectively,
“Hazardous Materials”) to be used, generated, stored or disposed of on, under or about, or transported to or from, the Premises (collectively, “Hazardous Materials Activities”) without first receiving
Landlord’s written consent, which may be withheld for any reason and revoked at any time. If Landlord consents to any such Hazardous Materials Activities, Tenant shall conduct them in strict compliance (at Tenant’s expense) with all
applicable Regulations, as hereinafter defined, and using all necessary and appropriate precautions. Landlord shall not be liable to Tenant for any Hazardous Materials Activities by Tenant, Tenant’s employees, agents, contractors, licensees or
invitees, whether or not consented to by Landlord. Tenant shall indemnify, defend with counsel acceptable to Landlord and hold Landlord harmless from and against any claims, damages, costs and liabilities arising out of Tenant’s Hazardous
Materials Activities. For purposes hereof, Hazardous Materials shall include but not be limited to substances defined as “hazardous substances,” “toxic substances,” or “hazardous wastes” in the federal Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended; the federal Hazardous Materials Transportation Act, as amended; and the federal Resource Conservation and Recovery Act, as amended (“RCRA”); those
substances defined as “hazardous wastes” in the Massachusetts Hazardous Waste Facility Siting Act, as amended (Massachusetts General Laws Chapter 21D); those substances defined as “hazardous materials” or “oil” in
Massachusetts General Laws Chapter 21E, as amended; and as such substances are defined in any regulations adopted and publications promulgated pursuant to said laws (collectively, “Regulations”). 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 as necessary for continued accuracy. Tenant shall also provide Landlord with a
copy of any Hazardous Materials inventory statement required by any applicable Regulations, and any update filed in accordance with any applicable Regulations. If Tenant’s activities violate or create a risk of violation of any Regulations,
Tenant shall cease such activities immediately upon notice from Landlord. Tenant shall immediately notify Landlord both by telephone and in writing of any spill or unauthorized discharge of Hazardous Materials or of any condition constituting an
imminent hazard under any Regulations. Landlord, Landlord’s representatives and employees may enter the 

  
 15 

 
Premises at any time during the Term after prior notice to inspect Tenant’s compliance herewith, and may disclose any violation of any Regulations to any governmental agency with
jurisdiction. Nothing herein shall prohibit Tenant from using minimal quantities of cleaning fluid and office supplies which may constitute Hazardous Materials but which are customarily present in premises devoted to office use, provided that such
use is in compliance with all applicable laws and subject to all of the other provisions of this Section 6.8. 
 ARTICLE
VII—DEFAULT 
 7.1 Events of Default. 

(a) The occurrence of any one or more of the following events (each, an “Event of Default”) shall constitute a default hereunder by
Tenant: 
 (i) The failure by Tenant to make any payment of Base Rent or additional rent or any other payment required
hereunder, as and when due, where such failure shall continue for a period of five (5) business days after written notice thereof from Landlord to Tenant. 

(ii) (Intentionally omitted). 

(iii) The failure by Tenant to observe or perform any of the express or implied covenants or provisions of this Lease to be
observed or performed by Tenant, other than as specified in clauses (i) and (ii) above, where such failure shall continue for a period of more than thirty (30) days after written notice thereof from Landlord to Tenant; provided,
however, that if the nature of Tenant’s default is such that more than thirty (30) days are reasonably required for its cure, then Tenant shall not be deemed to be in default if Tenant shall commence such cure within said thirty-day period and thereafter diligently prosecute such cure to completion, which completion shall occur not later than ninety (90) days from the date of such notice from Landlord. 

(iv) The failure by Tenant or any guarantor of any of Tenant’s obligations under this Lease to pay its debts as they
become due, or Tenant or any such guarantor becoming insolvent, filing or having filed against it a petition under any chapter of the United States Bankruptcy Code, 11 U.S.C. Section 101 et seq. (or any similar petition under any
insolvency law of any jurisdiction), proposing any dissolution, liquidation, composition, financial reorganization or recapitalization with creditors, making an assignment or trust mortgage for the benefit of creditors, or if a receiver, trustee,
custodian or similar agent is appointed or takes possession with respect to any property or business of Tenant or such guarantor. 
 (b) In
the event of any such default by Tenant, whether or not the Term shall have begun, in addition to any other remedies available to Landlord at law or in equity, Landlord shall have the immediate option, or the option at any time while such default
exists and without further notice, to terminate this Lease and all rights of Tenant hereunder by notice to Tenant; and this Lease shall thereupon come to an end as fully and completely as if the date such notice is given were the date herein
originally fixed for the expiration of the Term, and Tenant shall then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided. 

7.2 Damages. 
 (a) In the
event that this Lease is terminated under any of the provisions contained in Section 7.1 or shall be otherwise terminated for breach of any obligation of Tenant, Tenant covenants to pay forthwith to Landlord, as compensation, the excess
of the total rent reserved for the residue of the Term over the rental value of the Premises for said residue of the Term. In calculating the rent reserved there shall be included, in addition to the Base Rent and all additional rent, the value of
all other considerations agreed to be paid or performed by Tenant for said residue. Tenant further covenants as an additional and cumulative obligation after any such termination to pay punctually to Landlord all the sums and perform all the
obligations which Tenant covenants in this Lease to pay and to perform in the same manner and to the same extent and at the same time as if this Lease had not been terminated. In calculating the amounts to be paid by Tenant under the immediately
preceding covenant Tenant shall be credited with any amount paid to Landlord as compensation as in this Section 7.2 provided and also with the net proceeds of 

  
 16 

 
any rent obtained by Landlord by reletting the Premises, after deducting all Landlord’s reasonable expenses in connection with such reletting, including, without limitation, all repossession
costs, brokerage commissions, fees for legal services and expenses of preparing the Premises for such reletting, it being agreed by Tenant that Landlord may (i) relet 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 concessions and free rent as Landlord in its sole judgment considers advisable or necessary to
relet the same, and (ii) make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary to relet the same, and no action of Landlord in accordance with the foregoing or failure
to relet or to collect rent under reletting shall operate or be construed to release or reduce Tenant’s liability as aforesaid. 
 (b)
In lieu of any other damages or indemnity and in lieu of full recovery by Landlord of all sums payable under all the foregoing provisions of this Section 7.2, Landlord may by written notice to Tenant, at any time after this Lease is
terminated under any of the provisions contained in Section 7.1 or is otherwise terminated for breach of any obligation of Tenant and before such full recovery, elect to recover, and Tenant shall thereupon pay, as liquidated damages, an
amount equal to the aggregate of the Base Rent and additional rent accrued under Sections 3.1 and 3.2 in the 12 months (discounted to present value) ended next prior to such termination plus the amount of Base Rent and additional rent
of any kind accrued and unpaid at the time of termination and less the amount of any recovery by Landlord under the foregoing provision of this Section 7.2 up to the time of payment of such liquidated damages, similarly discounted to
present value. 
 (c) Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in proceedings
for bankruptcy or insolvency 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 provided, whether
or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. 
 (d) Landlord’s remedies
under this Lease are cumulative and not exclusive of any other remedies to which Landlord may be entitled in case of Tenant’s breach or threatened breach of this Lease. Landlord shall be entitled to the remedies of injunction and specific
performance with respect to any such breach. 
 ARTICLE VIII—CASUALTY AND EMINENT DOMAIN 

8.1 Termination or Restoration; Rent Adjustment. 

In case prior to or during the Term all or a substantial portion of the Premises or the Building are damaged by fire or other casualty or by
action of public or other authority in consequence thereof, or taken by eminent domain or access to the Building is eliminated by virtue of a taking by eminent domain or Landlord receives compensable damage by reason of anything lawfully done in
pursuance of public or other authority to such an extent that it is reasonably determined by the Landlord that the Premises or Building shall not be restored, this Lease shall by notice to Tenant from Landlord terminate, which may be made
notwithstanding Landlord’s entire interest may have been divested. Notwithstanding anything to the contrary contained herein, Landlord agrees not to terminate this Lease unless Landlord is terminating the leases of similarly affected Building
tenants. The effective date of termination specified by Landlord shall not be less than forty-five (45) nor more than ninety (90) days after the date of notice of such termination. Further, during
the Term, in the event of (a) damage to the Premises which makes a material portion of the Premises unfit for use and occupancy, or (b) damage to a material portion of the common facilities necessary for the practical use and enjoyment of
the Premises (including, without limitation, any material portion of the common facilities which provide access to the Premises), or (c) a permanent taking of a material portion of the Premises, or (d) a permanent taking of a material
portion of the common facilities necessary for the practical use and enjoyment of the Premises (including, without limitation, any material portion of the common facilities which provide access to the Premises), Tenant may, by notice given to
Landlord within 30 days of such casualty or taking, notify Landlord of its desire to terminate this Lease. If such a notice is given, this Lease shall terminate 90 days after such notice is given unless, in the case of (a) or (b) above,
within 90 days of the giving of such notice, Landlord delivers to Tenant its certification (a “Landlord’s Restoration Certification”) that the Landlord intends to restore the Premises (including, without limitation, the
Leasehold Improvements) and the common facilities, as the case may be, to substantially the condition they were in prior to such casualty or taking within 210 days of the event giving rise to such notice (the “Outside Restoration
Date”), and in the case of (d) above, the 

  
 17 

 
Landlord intends to replace what remains of the common facilities by the Outside Restoration Date so that Tenant will again be able to have the practical use and enjoyment of the Premises to
substantially the same extent as prior to such taking. Unless terminated pursuant to the foregoing provision, this Lease shall remain in full force and effect following any damage or taking, subject, however, to the following provisions, and subject
further to the additional right of Tenant to terminate this Lease if the restoration of the Premises or the common facilities has not occurred by the Outside Restoration Date (such date being extended by the number of days, not to exceed 30 in the
aggregate, specified in a notice or notices given from time to time by Landlord to Tenant prior to the then applicable Outside Restoration Date, of delays in completion attributable to the occurrence of a Force Majeure Event). Tenant may not
exercise such additional right to terminate this Lease except within 30 days after the Outside Restoration Date (as so extended by such a notice or notices). Notwithstanding the foregoing, upon the occurrence of a casualty or taking of the nature
hereinabove described in clauses (a), (b), (c) or (d), which occurs within the last thirty (30) months of the Term, Landlord and Tenant shall have the option to terminate this Lease upon written notice to the other party. 

If in any such case the Premises or any portion thereof are rendered unfit for use and occupation or any portion of the common facilities
necessary for the practical use and enjoyment of the Premises are unavailable for use and this Lease is not so terminated, Landlord shall use due diligence (following the expiration of the period in which this Lease may be terminated pursuant to the
foregoing provisions of this Section 6.1.2), subject to the availability of insurance proceeds and consent of the holders of any mortgages on the Property, Building or both, to put the Premises, and any portion of the common facilities
necessary for the practical use and enjoyment of the Premises or in case of a taking what may remain thereof (excluding in case of both damage and taking any items installed or paid for by Tenant), into substantially the condition the Premises were
in prior to such casualty or taking. A just proportion of the fixed rent and additional rent according to the nature and extent of the injury shall be abated from the time of the damage or taking until the Premises or such portion of the common
facilities or such remainder shall have been put into proper condition for use and occupation or until termination of this Lease, and in case of a taking which permanently reduces the area of the Premises, a just proportion of the fixed rent and
additional rent shall be abated for the remainder of the Term. 
 8.2 Eminent Domain Damages. 

Landlord reserves to itself any and all rights to receive awards made for damages to the Premises and Building and the leasehold hereby
created, or any one or more of them, accruing by reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby releases and assigns to Landlord all Tenant’s rights to such
awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request, hereby irrevocably designating and appointing Landlord as its
attorney-in-fact to execute and deliver in Tenant’s name and behalf all such further assignments thereof. Nothing contained herein shall be deemed to preclude
Tenant from obtaining, or to give Landlord any interest in, any separate award to Tenant for loss or damage to Tenant’s removable personal property or Tenant’s relocation costs. 

8.3 Temporary Taking. 

In the event of any taking of the Premises or any part thereof for temporary use, (i) this Lease shall be and remain unaffected thereby
and rent shall not abate, and (ii) Tenant shall be entitled to receive for itself such portion or portions of any award made for such use with respect to the period of the taking which is within the Term. 

ARTICLE IX—RIGHTS OF PARTIES HOLDING PRIOR INTERESTS 

9.1 Lease Subordinate—Superior. 

This Lease shall be subject and subordinate to the lien of any institutional first mortgage (“Mortgage”) now or hereinafter
placed on the Property, the Building, or both, or any portion or portions thereof or interest therein, which are separately and together hereinafter in this Article IX referred to as “the mortgaged premises”, and to each advance made or
hereafter to be made under any Mortgage, and to all renewals, modifications, consolidations, replacements and extensions thereof and all substitutions therefor. 

  
 18 

 In the event that any mortgagee or its successor in title shall succeed to the interest of
Landlord, then, Tenant shall and does hereby agree to attorn to such mortgagee or successor and to recognize such mortgagee or successor as its Landlord. Any claim by Tenant under the Lease against the mortgagee or such successor shall be satisfied
solely out of the mortgagee’s or such successor’s interest in the Building and Tenant shall not seek recovery against or out of any other assets of mortgagee or such successor. Notwithstanding the foregoing, any mortgagee may at its
election subordinate its Mortgage to this Lease without the consent or approval of Tenant. This Section shall be self-operative. Tenant agrees to execute and deliver promptly any commercially reasonable
certificates or instruments requested by Landlord or any mortgagee to carry out the subordination and attornment agreements contained in this Section 9.1. 

Notwithstanding anything in this Lease to the contrary, Landlord shall use commercially reasonable efforts to obtain for Tenant from any
current or future mortgagee on the Building or the Property a non-disturbance agreement for the benefit of Tenant, at Tenant’s cost, in a commercially reasonable form prepared by such mortgagee, whereby the mortgagee agrees to recognize the
rights of Tenant under this Lease in the event of foreclosure of the Mortgage held by it, so long as Tenant is not in default hereunder, after notice to Tenant and expiration of applicable grace and cure periods. 

9.2 Rights of Mortgagee to Cure. 

No act or failure to act on the part of Landlord which would entitle Tenant, under the terms of this Lease or as a matter of law, to be
released from Tenant’s obligations hereunder or to terminate this Lease shall result in a release of such obligations or a termination of this Lease unless Tenant first gives written notice of and a specific description of Landlord’s act
or failure to act to Landlord’s mortgagees of whom Tenant has been given written notice by Landlord, if any, and such mortgagee fails to cure such default within thirty (30) days after receipt of such notice. However, if such cure
reasonably requires more than thirty days to effect, such mortgagee shall have such additional time as is reasonably necessary in the circumstances, including time to take possession of the Property. This section shall not impose any obligation on
any such mortgagee. Landlord shall, from time to time, notify Tenant as to the identity of Landlord’s mortgagees; provided, however, that Tenant’s execution of estoppel certificates, nondisturbance agreements or similar agreements which
identify Landlord’s mortgagee shall be deemed to be notice to Tenant hereunder. 
 ARTICLE X—MISCELLANEOUS 

10.1 Representations by Tenant. 

Each party represents and warrants to the other party that those persons executing this Lease on its behalf are duly authorized to execute and
deliver this Lease on its behalf, and that this Lease is binding upon such party in accordance with its terms and upon execution of this Lease, each party shall deliver evidence of such authority to the other party in form satisfactory to the other
party. 
 10.2 Notices. 

Any notice required or permitted hereunder shall be in writing. Communications shall be addressed to Landlord at Landlord’s Address and
to Tenant at Tenant’s Address if prior to the Commencement Date and to Tenant at the Premises if following the Commencement Date. Any communication so addressed shall be deemed duly given when delivered by hand, one day after being sent by
Federal Express (or other guaranteed one day delivery service) or three days after being sent by registered or certified mail, return receipt requested. Either party may change its address by giving notice to the other. 

10.3 No Waiver or Oral Modification. 

No provision of this Lease shall be deemed waived by Landlord or Tenant except by a signed written waiver. No consent to any act or waiver of
any breach or default, express or implied, by Landlord or Tenant, shall be construed as a consent to any other act or waiver of any other breach or default. Landlord’s failure to enforce any covenant or condition of this Lease shall not be
deemed a waiver thereof, and its failure to enforce any of the Rules 

  
 19 

 
and Regulations against Tenant or any other tenant in the Building shall not be deemed a waiver thereof. The receipt by Landlord of any rent with knowledge of the breach of any covenant of this
Lease shall not be deemed a waiver of such breach, and the acceptance of any rental payment in any amount less than the full sum due shall not constitute a waiver of any claim to the remaining balance. This Lease may not be changed or amended
orally, but only by written instrument signed by both parties hereto. 
 10.4 Partial Invalidity. 

If any provision of this Lease, or the application thereof in any circumstances, shall to any extent be invalid or unenforceable, the
remainder of this Lease shall not be affected thereby, and each provision hereof shall be valid and enforceable to the fullest extent permitted by law. 

10.5 Certain Landlord Remedies. 

If Tenant fails to perform any obligation hereunder after notice to Tenant and expiration of applicable grace and cure periods, Landlord may,
upon ten (10) days prior written notice to Tenant (except in the case of emergency in which case no notice shall be required), enter the Premises and perform it on Tenant’s behalf. In so doing, Landlord may make any payment of money or
perform any other act. All sums so paid by Landlord, and all incidental out-of-pocket costs and expenses, shall be considered additional rent under this Lease and shall be payable to Landlord within ten (10) days of demand, together with
interest from the date of demand to the date of payment at the “Interest Rate.” For purposes of this Lease, the Interest Rate shall mean the lesser of the maximum interest rate permitted by law or three (3) percentage points above the
then prevailing prime rate as set by Bank of America in its main office in Boston, MA (or, if such bank ceases to exist, the then largest bank in the Commonwealth of Massachusetts). 

10.6 Tenant’s Estoppel Certificate. 

Within ten (10) days after written request by Landlord, Tenant shall execute, acknowledge and deliver to Landlord a written statement
certifying (a) that this Lease is unmodified and in full force and effect, or is in full force and effect as modified and stating the modifications; (b) the amount of Base Rent and the date to which Base Rent and additional rent have been
paid in advance; (c) the amount of any security deposited with Landlord; and (d) that, to the best of Tenant’s actual knowledge, Landlord is not in default hereunder or, if Landlord is claimed to be in default, stating the nature of
any claimed default, and (e) such other matters as may be reasonably requested by Landlord. Any such statement may be relied upon by a purchaser, assignee or lender. Tenant’s failure to execute and deliver such statement within the time
required shall be a default under this Lease and shall also be conclusive upon Tenant that (1) this Lease is in full force and effect and has not been modified except as represented by Landlord; (2) there are no uncured defaults in
Landlord’s performance and Tenant has no right of offset, counterclaim or deduction against rent; and (3) not more than one month’s Base Rent has been paid in advance. In connection with any Transfer of this Lease or major corporate
financing by Tenant, Landlord shall, within twenty (20) days after written request by Tenant, acknowledge and deliver to Tenant a written statement containing substantially similar certifications regarding Tenant to those listed above regarding
Landlord (provided that Tenant reimburses Landlord for its reasonable legal and other expenses in connection with such request). 
 10.7
Waiver of Subrogation. 
 Notwithstanding anything to the contrary contained in this Lease, Landlord and Tenant each hereby waive on
behalf of itself and its property insurers (none of which shall ever be assigned any such claim or be entitled thereto due to subrogation or otherwise) all rights of recovery, claim, action or cause of action against the other and against the
officers, employees, agents, and representatives of the other, on account of loss by or damage to the waiving party or its property or the property of others under its control, if such loss or damage is of such a nature as is actually insured
against under any insurance policy that either may have in force at the time of the loss or damage or is required to be insured against by the waiving party hereunder whether or not such insurance is actually maintained and regardless of the cause
or origin, including, in every instance, negligence by the other party hereto, its agents, officers, partners or employees. Each party shall notify its insurers that the foregoing waiver is contained in this Lease. Landlord and Tenant shall cause
each insurance policy obtained by each of them to provide that the insurer waives all right of recovery by way of subrogation against either Landlord or Tenant in connection with any loss or damage covered by such policy. 

  
 20 

 10.8 All Agreements; No Representations. 

This Lease contains all of the agreements of the parties with respect to the subject matter hereof and supersedes all prior dealings between
them with respect to such subject matter. Each party acknowledges that the other has made no representations or warranties of any kind except as may be specifically set forth in this Lease. 

10.9 Brokerage. 
 Each
party represents and warrants that it has not dealt with any real estate broker or agent in connection with this Lease or its negotiation other than the “Brokers” identified in Section 1.2 who shall be paid by Landlord pursuant
to a separate agreement. Each party shall indemnify the other and hold it harmless from any cost, expense, or liability (including costs of suit and reasonable attorneys’ fees) for any compensation, commission or fees claimed by any other real
estate broker or agent in connection with this Lease or its negotiation by reason of any act or statement of the indemnifying party. 

10.10 Successors and Assigns. 

This Lease shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided,
however, that the original Landlord named herein and each successive owner of the Premises shall be liable only for obligations accruing during the period of their respective ownership; provided further, that Tenant’s right to make a Transfer
shall always be governed by Section 6.3 hereof. 
 10.11 Construction of Document. 

This Lease shall be construed, governed and enforced according to the laws of the state where the Property is located. In construing this
Lease, section headings shall be disregarded. Any recitals herein or riders or exhibits attached hereto are hereby incorporated into this Lease by this reference. Time is of the essence of this Lease and every provision contained herein. The parties
acknowledge that this Lease was freely negotiated by both parties, each of whom was represented by counsel; accordingly, this Lease shall be construed according to the fair meaning of its terms, and not against either party. 

10.12 Disputes Provisions. 

(a) If either Landlord or Tenant institutes any action to enforce the provisions of this Lease or to seek a declaration of rights hereunder,
the prevailing party shall be entitled to recover its reasonable attorneys’ fees and court costs as part of any award. 
 (b) Landlord
and Tenant hereby waive trial by jury in any action, proceeding or counterclaim (excluding mandatory counterclaims) brought by either of the parties hereto against the other, on or in respect to any matter whatsoever arising out of or in any way
connected with this Lease, the relationship of Landlord and Tenant hereunder, Tenant’s use or occupancy of the Premises, and/or claim of injury or damage. 

10.13 Surrender. 
 The
voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and shall, at the option of Landlord, operate as an assignment to it of any or all subleases or subtenancies. 

  
 21 

 10.14 Holdover. 

If Tenant holds over in occupancy of the Premises after the expiration of the Term, Tenant shall become a tenant at sufferance only, at a pro
rated rental rate equal to one hundred fifty (150%) percent of the Rent in effect at the end of the Term, and otherwise subject to the terms and conditions herein specified, so far as applicable, and shall be liable for all damages sustained by
Landlord on account of such holding over. This Section shall not operate as a waiver of any right of reentry provided in this Lease, and Landlord’s acceptance of rent after expiration of the Term or earlier termination of this Lease shall not
constitute consent to a holdover or result in a renewal. If Tenant fails to surrender the Premises upon the expiration of the Term or earlier termination despite demand by Landlord to do so, Tenant shall indemnify and hold Landlord harmless from all
loss or liability, including, without limitation, any claim made by any succeeding tenant resulting from such failure. 
 10.15 Late
Payment. 
 Tenant acknowledges that the late payment by Tenant to Landlord of any sums due under this Lease will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of such costs being extremely difficult and impractical to ascertain. Therefore, if any monthly payment is not paid on or by the date it is due more than once during any twelve
(12) month period, Tenant shall pay to Landlord an administrative fee equal to five (5%) percent of the unpaid amount. In addition, Tenant shall pay to the Landlord interest at a rate of 2% plus the prime rate per annum published as such
in the Wall Street Journal on all sums whatever becoming due under this lease, and not paid within five (5) days after their due date, if called upon the Landlord to do so. Landlord’s acceptance of any late charge or interest shall
not constitute a waiver of Tenant’s default with respect to the overdue amount. 
 10.16 Force Majeure. 

If Landlord or Tenant is prevented from or delayed in performing any act required of it hereunder, and such prevention or delay is caused by
strikes, labor disputes, inability to obtain labor, materials, or equipment, inclement weather, acts of God, governmental restrictions, regulations, or controls, judicial orders, enemy or hostile government actions, civil commotion, fire or other
casualty, or other causes beyond such party’s reasonable control (collectively, “Force Majeure”), the performance of such act shall be excused for a period equal to the period of prevention or delay. A party’s financial
inability to perform its obligations shall in no event constitute Force Majeure. Nothing in this section shall excuse or delay Tenant’s obligation to pay any rent or other charges due under this Lease. 

10.17 Limitation On Liability. 

In consideration of the benefits accruing hereunder, Tenant hereby covenants and agrees that, in the event of any actual or alleged failure,
breach or default hereunder by Landlord: 
 (a) The obligations of Landlord and Tenant under this Lease do not constitute
personal obligations of the trustees, individual partners, directors, officers or shareholders of either Landlord or Tenant, Landlord’s or Tenant’s beneficiary or any constituent partner of Landlord’s or Tenant’s beneficiary, and
neither Landlord nor Tenant shall seek recourse against the trustees, partners, directors, officers or shareholders of the other party, the other party’s beneficiary or any constituent partner of the other party’s beneficiary or any of
their personal assets for satisfaction of any liability with respect to this Lease. 
 (b) Tenant’s sole and exclusive
remedy shall be against the Landlord’s interest in the Property. 
 (c) Neither Landlord’s beneficiary nor any
constituent partner of Landlord’s beneficiary shall be sued, named as a party in any suit or action, or served with process therein (except if necessary to secure jurisdiction), and neither Landlord’s beneficiary nor any constituent
partner of Landlord’s beneficiary shall be required to respond to any service of process. 
 (d) No judgment will be
taken against Landlord’s beneficiary nor any constituent partner of Landlord’s beneficiary, and no writ of execution will be levied against the assets of Landlord’s beneficiary or any such partner. 

  
 22 

 (e) These covenants and agreements are enforceable both by Landlord and also by
Landlord’s beneficiary, any constituent partner of Landlord’s beneficiary, and shall bind Tenant and its successors and assigns. 

(f) Notwithstanding any provision of this Lease to the contrary (including, without limitation, any indemnification provision),
in no event shall Landlord, Tenant or any of their directors, officers, shareholders, employees, advisers or agents be responsible for interruption or loss of business, income or profits, or any other consequential, indirect or special damages. 

10.18 Submission Not An Option. 

The submission of this Lease or a summary of some or all of its provisions for examination by Tenant does not constitute a reservation of the
Premises for Tenant or an offer to lease the Premises to Tenant or the grant of an option for the Premises to Tenant, notwithstanding any contrary provision of statutory or common law. 

10.19 Security Deposit. 

Tenant agrees that the Security Deposit shall be in the form of a letter of credit to be delivered upon the execution of this Lease, the
letter of credit shall be an irrevocable letter of credit (the “Letter of Credit”), issued in a form and by a bank reasonably approved by Landlord (the “Bank”) in the amount of the Security Deposit. Without limiting the
generality of the foregoing, the Letter of Credit shall name Landlord as the beneficiary and provide that it may be negotiated or drawn against upon the furnishing of a statement to the Bank, from an authorized officer or agent of Landlord, that the
Letter of Credit is being drawn upon in accordance with the terms of this Lease. Landlord shall hold the Letter of Credit as security for the performance by Tenant of all obligations on the part of Tenant to be kept and performed. Landlord shall
have the right, from time to time upon an Event of Default that remains uncured, without prejudice to any other remedy Landlord may have on account thereof, to draw upon the Letter of Credit and apply such funds to Landlord’s damages arising
from any Event of Default on the part of Tenant, in which event Tenant shall restore the balance of the Letter of Credit to the amount required hereunder. Tenant shall maintain the Letter of Credit, or a substitute Letter of Credit from a bank
reasonably approved by Landlord, in accordance with the terms hereof, in full force and effect at all times during the entire Term and for a period of thirty (30) days thereafter (the last day of such 30 day period shall be referred to herein
as the “Return Date”). 
 If the Letter of Credit shall expire before the Return Date, Tenant shall replace the Letter of
Credit deposited with Landlord by providing Landlord with a substitute Letter of Credit at least thirty (30) days prior (each such 30th day prior being referred to herein as a “Change Date”) to the expiration date of then
effective Letter of Credit being held by Landlord, in the applicable amount required hereby. Any failure by Tenant to provide such a substitute Letter of Credit shall be an Event of Default under this Lease for which there shall be no grace period
and shall entitle Landlord to draw on all funds available under the Letter of Credit then being held by Landlord as amounts due hereunder and hold the same as security for Tenant’s performance of its obligations under this Lease. The Security
Deposit shall not be used by Tenant as a payment of rent due for the final months of the Term. 
 10.20 Evidence of Authority. 

Simultaneously with the execution hereof, Tenant shall deliver to Landlord evidence, satisfactory to Landlord’s counsel, as to the
authority of the persons executing this Lease on behalf of Tenant to enter into, execute, deliver and bind Tenant to this Lease. 
 10.21
Relocation. 
 Intentionally omitted

 10.22 Notice of Lease. 

Tenant agrees not to record this Lease, but upon request of either party, both parties shall execute and deliver a notice of this Lease in
form appropriate for recording or registration, and if this Lease is terminated before the Term expires, an instrument in such form acknowledging the date of termination. 

10.23 Option to Extend. Provided that Tenant is not in default of the performance or observation of any of the terms or provisions of
this Lease after notice to Tenant and expiration of applicable grace and cure periods (as defined in Section 7.1 herein), Tenant may elect to extend the Term of this Lease for one (1) additional period of five (5) years (the
“Extension Term”), by giving Landlord notice of such election no later than twelve (12) months prior to the expiration of the initial Term. Such extension shall be upon the terms, covenants, and conditions contained in this
Lease except that Tenant shall have no further right to extend the Term and that the Base Rent for the Extension Term shall be at fair market rent for comparable space in comparable properties in the Watertown area taking into account all relevant
factors. 
 If Landlord and Tenant are unable to agree on the amount of such fair market rent by the date that is thirty (30) days
after the date of Tenant’s election notice based on rental rates and terms for comparable space in the Greater Boston area, then Landlord shall promptly specify in writing the rent (the “Landlord’s Rental Rate”) at which
Landlord is willing to lease the Premises for the Extension Term and Tenant shall promptly specify in writing the rent ( the “Tenant’s Rental Rate”) which Tenant is willing to pay for the Premises for the Extension Term and the
amount of the fair market rent shall be established by appraisal in the following manner. The Landlord and Tenant shall each appoint one appraiser and the two appraisers so appointed shall determine the fair market rent within thirty days of
Tenant’s election notice. If such appraisers are unable to agree on the amount of such fair market rent within such 30-day period, they shall appoint a third appraiser within ten (10) days of the expiration of such period, who shall be
instructed to select, as between the rents chosen by the two appraisers, the rent that is closest to the third appraiser’s estimate of Fair Market Rent. The fair market rent shall be the amount so selected by the third appraiser and shall be
conclusive on the Landlord and Tenant. 
 Each party shall bear the cost of its appraiser, and the cost of the third appraiser shall be
split equally between parties. The third appraiser’s estimate shall be based on the data supplied and used by the original two appraisers and the findings made by the third appraiser shall be set forth in writing.
