 ARTICLE II

 PREMISES 
  

	2.1	DEMISE AND LEASE OF PREMISES. 


(A) Landlord hereby demises and leases to Tenant, and Tenant hereby hires and accepts from Landlord, the Premises in the Building,
excluding exterior faces of exterior walls, the common stairways and stairwells, elevators and elevator walls, mechanical rooms, electric and telephone closets, janitor closets, and pipes, ducts, shafts, conduits, wires and appurtenant fixtures
serving exclusively or in common other parts of the Building, and if the Premises includes less than the entire rentable area of any floor, excluding the common corridors, elevator lobbies and toilets located on such floor. 

(B) The parties acknowledge and agree that: (i) they have agreed upon the Rentable Floor Area of the Premises and the entire
Building, and (ii) such agreed upon amounts are set forth in Section 1.2 of this Lease. Neither party shall have any right to remeasure the Premises. 
  

	2.2	APPURTENANT RIGHTS AND RESERVATIONS. 


(A) Subject to Landlord’s right to change or alter any of the following in its discretion as provided in this Section 2.2,
Tenant shall have, as appurtenant to the Premises, the non-exclusive right to use in common with others, but not in a manner or extent that would materially interfere with the normal operation and use of the Building as a multi-tenant office
building and subject to Rules and Regulations (as set forth in Section 16.32): (a) the common lobbies, corridors, stairways, and elevators of the Building, and the pipes, ducts, shafts, conduits, wires and appurtenant meters and equipment
serving the Premises in common with others (“Common Areas”), (b) the loading areas serving the Building and the 

 

 5 








 
common walkways and driveways necessary for access to the Building, and (c) if the Premises include less than the entire rentable floor area of any floor, the common toilets, corridors and
elevator lobby of such floor. Notwithstanding anything to the contrary herein or in the Lease contained, Landlord has no obligation to allow any particular telecommunication service provider to have access to the Building or to Tenant’s
premises, but Landlord shall not be unreasonable in denying such access. If Landlord permits such access, Landlord may condition such access upon the payment to Landlord by the service provider of commercially reasonable fees assessed by Landlord in
its reasonable discretion, if other building owners of similar buildings in the greater Boston area are then assessing such fees. Provided that and so long as Tenant’s telecommunications service provider (“Provider”) does not provide
telecommunications service to any other tenant of the Building, Landlord shall not require such Provider to pay any fees for such access. 

(B) Landlord reserves the right from time to time, without unreasonable interference with Tenant’s use: (a) to install, use,
maintain, repair, replace and relocate for service to the Premises and other parts of the Building, or either, pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises or the Building, and (b) to alter or
relocate any other common facility, provided that substitutions are substantially equivalent or better. Installations, replacements and relocations referred to in clause (a) above shall be located, so far as practicable, in the central core
area of the Building, above ceiling surfaces, below floor surfaces or within perimeter walls of the Premises. Except in the case of emergencies or for normal cleaning or maintenance operations, Landlord agrees to give Tenant reasonable advance
notice (which may be oral) of any of the foregoing activities which require work in the Premises. In making any entry into the Premises, Landlord shall use reasonable efforts to minimize interference with the Tenant’s use and enjoyment of the
Premises. 
 (C) Landlord reserves and excepts for its benefit all rights of ownership and use in all respects outside the
Premises, including without limitation, the Building and Common Areas in connection therewith, except that at all times during the Term of this Lease Tenant shall have a reasonable means of access from First Street to the Premises. Without
limitation of the foregoing reservation of rights by Landlord, it is understood that in its sole discretion Landlord shall have the right to change and rearrange the Common Areas, to change, relocate and eliminate facilities therein, to permit the
use of or lease all or part thereof for exhibitions and displays and to sell, lease or dedicate all or part thereof to public use; and further that (subject to the provisions of Section 2.2(B)(b)) Landlord shall have the right to make changes
in additions to and eliminations from the Building, the Premises excepted; provided however that Tenant, its employees, agents, clients, customers, and invitees shall at all times have reasonable access to the Building and Premises. So long as
Tenant shall comply with Landlord’s 
  

 6 








 
reasonable security program for the Building, and subject to circumstances beyond Landlord’s reasonable control, Tenant shall have access to the Premises twenty-four (24) hours per day,
seven (7) days per week during the term of this Lease. Landlord is not under any obligation to permit individuals without proper building identification to enter the Building after 6:00 p.m., unless Tenant makes appropriate arrangements with
Landlord beforehand. 
 ARTICLE III 

LEASE TERM AND EXTENSION OPTIONS 
  

	3.1	TERM. The Term of this Lease shall be the period specified in Section 1.2 hereof as the “Lease Term”, unless sooner terminated or extended as
herein provided. The Lease Term hereof shall commence on, and the Commencement Date shall be, the first to occur of: 

  

	 	(a)	The day on which the Premises are substantially complete, as defined in Section 4.1 hereof, but not earlier than the Estimated Commencement Date, as set forth in
Section 1.2; or 

  

	 	(b)	The date upon which Tenant commences beneficial use of the Premises. 


Tenant shall, in all events, be treated as having commenced beneficial use of the Premises when it begins to utilize the Premises for its
regular business operations. 
 At the request of either Landlord or Tenant and as soon as may be convenient after a Commencement
Date has been determined, Landlord and Tenant agree to join with each other in the execution, in the form of Exhibit E hereto, of a written Commencement Date Agreement in which such Commencement Date, Rent Commencement Date and specified Lease Term
of this Lease shall be stated. 
  

	3.2	EXTENSION OPTIONS: 

  

	(A)	 Options. On the conditions (which conditions Landlord may waive by written notice to Tenant) that, both at the time of exercise of the herein
described option to extend and as of the commencement of the Extended Term in question: (i) there exists no “Event of Default” (defined in Section 15.1), (ii) this Lease is still in full force and effect, and
(iii) Zipcar, Inc. itself, a Permitted Tenant Successor, and/or Tenant Affiliates occupy at least seventy-five percent (75%) of the Rentable Floor Area of the Premises then demised to Tenant, then Tenant shall have the right to extend the
Term hereof upon all the same terms, conditions, covenants and agreements herein contained from the original expiration date hereof for one (1) period(s) of five (5) years each as hereinafter set forth. Notwithstanding the foregoing, the
Annual Fixed Rent shall be equal to the Fair Market Rental Value as determined in accordance with Paragraph (B) of this Section 3.2, of the 



 

 7 









	 	
Premises then demised to Tenant, as of the commencement of the Extended Term in question. Except as set forth in this Paragraph (A), there shall be no further option to extend. Each option period
is sometimes herein referred to as the “Extended Term.” Notwithstanding any implication to the contrary Landlord has no obligation to make any additional payment to Tenant in respect of any construction allowance or the like or to perform
any work to the Premises as a result of the exercise by Tenant of any such option. 

 (B) If Tenant desires to
exercise an option to extend the Term, then Tenant shall give notice (“Exercise Notice”) to Landlord, not earlier than twelve (12) months nor later than nine (9) months prior to the expiration of the then Term of this Lease (as
it may have been previously extended) exercising such option to extend. Promptly after Landlord’s receipt of the Exercise Notice, Landlord shall provide Landlord’s quotation to Tenant of its good faith estimate of the Fair Market Rental
Value of the Premises for the Extended Term (“Landlord’s Rent Quotation”). If at the expiration of thirty (30) days after the date when Landlord provides such quotation to Tenant (the “Negotiation Period”), Landlord and
Tenant have not reached agreement on a determination of an Annual Fixed Rent for such Extended Term and executed a written instrument memorializing such agreement, then Tenant shall have the right, for thirty (30) days following the expiration
of the Negotiation Period, to make a request to Landlord for a determination (the “Determination”) of the Fair Market Rental Value of the Premises (as defined in Exhibit G) for such Extended Term, which Determination shall be made in the
manner set forth in Exhibit G. If Tenant timely shall have requested the Determination, then the Annual Fixed Rent for such Extended Term shall be the Prevailing Market Rent as determined by the Determination. If Tenant does not timely request the
Determination, then the Annual Fixed Rent during such Extended Term shall be equal to Landlord’s Rent Quotation. 
 Tenant
shall also have the right, but not the obligation, to request that Landlord provide a Landlord’s Rent Quotation prior to Tenant giving Landlord the Exercise Notice. Tenant shall exercise such right by sending Landlord a notice (“Inquiry
Notice”), not earlier than thirteen (13) months prior to the expiration of the then Term of this Lease (as it may have been previously extended) requesting such a quotation. Tenant’s Inquiry Notice shall clearly state thereon that it
is not an Exercise Notice. Landlord’s only obligation with respect to an Inquiry Notice shall be to provide a Landlord’s Rent Quotation within thirty (30) days after receipt thereof. The Inquiry Notice shall not act to exercise
Tenant’s option to extend the Term of this Lease, or otherwise in any way alter the terms and conditions of this Section 3.2 including, without limitation, Tenant’s obligation to timely give the Exercise Notice in order to exercise
its option to extend the Term of this Lease. 
  

 8 








 (C) Upon the giving of the Exercise Notice by Tenant to Landlord exercising Tenant’s
applicable option to extend the Lease Term in accordance with the provisions of Section 3.2 (B) above, then this Lease and the Lease Term hereof shall automatically be deemed extended, for the applicable Extended Term, without the
necessity for the execution of any additional documents, except that Landlord and Tenant agree to enter into an instrument in writing setting forth the Annual Fixed Rent for the applicable Extended Term as determined in the relevant manner set forth
in this Section 3.2; and in such event all references herein to the Lease Term or the Term of this Lease shall be construed as referring to the Lease Term, as so extended, unless the context clearly otherwise requires, and except that there
shall be no further option to extend the Lease Term. If Tenant fails to timely give the Exercise Notice to Landlord pursuant to the provisions of Section 3.2(B) above, then Tenant shall have no right to extend the Lease Term. Notwithstanding
anything contained herein to the contrary, in no event shall the Lease Term hereof be extended for more than five (5) years after the expiration of the Original Lease Term hereof. 

ARTICLE IV 

CONSTRUCTION 
  

	4.1	SUBSTANTIAL COMPLETION. 

  

	 	(A)	Plans and Construction Process. 


(1) Landlord’s Work. Landlord shall, at Landlord’s sole cost and expense except for Change Orders as set forth
below, perform the work shown on the plans (the “Plans”) listed on Exhibit B annexed hereto utilizing Building standard materials as listed on Exhibit B-1 annexed hereto (the “Building Standard Specifications”)
(“Landlord’s Work”); provided, however, that Landlord shall have no responsibility for the installation or connection of Tenant’s computer, telephone, other communication equipment, systems or wiring. Any items of work requested
by Tenant and not shown on the Plans and/or the Building Standard Specifications shall be deemed to be Change Proposal(s) (as defined below) and shall be subject to the terms and provisions of subsection (2) below. 

(2) Change Orders. Tenant shall have the right, in accordance herewith, to submit for Landlord’s approval change
proposals with respect to items of work not shown on the Plans and/or the Building Standard Specifications (each, a “Change Proposal”). Landlord agrees to respond to any such Change Proposal within such time as is reasonably necessary
(taking into consideration the information contained in such Change Proposal) after the submission thereof by Tenant, advising Tenant of any anticipated costs (“Change Order Costs”) associated with such Change Proposal, as well as an
estimate of any delay which would likely result in the completion of the Landlord’s Work if a Change Proposal is made 
  


 9 








 
pursuant thereto and an indication that such delay may qualify as a Tenant Delay pursuant to the provisions of Section 4.1(C) of this Lease (“Landlord’s Change Order
Response”). If Landlord cannot provide Tenant with all of the information required in Landlord’s Change Order Response within two (2) business days after the submission of such Change Proposal by Tenant, Landlord shall nonetheless
respond to Tenant (“Landlord’s Status Response”) within such two (2) business day period informing Tenant that Landlord cannot fully respond within such period, and giving an estimate, based on Landlord’s reasonable
judgment, of when a full response will be forthcoming. Tenant shall have the right to then approve or withdraw such Change Proposal within two (2) business days after receipt of such Landlord’s Change Order Response, and the right to
withdraw such Change Proposal at any time after Landlord’s Status Response up until the time two (2) business days after receipt of Landlord’s Change Order Response with respect to the Change Proposal in question. If Tenant fails to
respond to Landlord’s Change Order Response within such two (2) business day period, such Change Proposal shall be deemed withdrawn. If Tenant approves such Change Proposal, then such Change Proposal shall be deemed a “Change
Order” hereunder and if the Change Order is made, then the Change Order Costs associated with the Change Order shall be deemed additions to the Tenant Plan Excess Costs and shall be paid in the same manner as Tenant Plan Excess Costs are paid
as set forth in Section 4.5. 
 (3) Tenant Response to Requests for Information and Approvals. Except to the
extent that another time period is expressly herein set forth, Tenant shall respond to any request from Landlord, Landlord’s architect, Landlord’s contractor and/or Landlord’s Construction Representative for approvals or information
in connection with Landlord’s Work, within four (4) business days of Tenant’s receipt of such request. In addition, Tenant shall, within four (4) business days after receipt thereof from Landlord, execute and deliver to Landlord
any affidavits and documentation required in order to obtain all permits and approvals necessary for Landlord to commence and complete Landlord’s Work on a timely basis (“Permit Documentation”). 

(4) Time of the Essence. Time is of the essence in connection with Tenant’s obligations under this Section 4.1.

 (B) Substantial Completion; Tenant Delay. 

(1) Landlord’s Obligations. Subject to delays due to governmental regulation, strikes, lockouts, acts of God, acts of
war, terrorists acts, civil commotions, unusual scarcity of or inability to obtain labor or materials, labor difficulties, casualty or other causes reasonably beyond Landlord’s control or attributable to Tenant’s action or inaction
(collectively “Landlord’s Force Majeure” ) Landlord shall use reasonable speed and diligence to have the Landlord’s Work substantially completed on or before the Estimated 

 

 10 








 
Commencement Date, but Tenant shall have no claim against Landlord for failure so to complete construction of Landlord’s Work in the Premises, except for the right to terminate this Lease,
without further liability to either party, in accordance with the provisions hereinafter specified in Section 4.2. 
 (2)
Definition of Substantial Completion. The Premises shall be treated as having been substantially completed and be deemed ready for Tenant’s occupancy on the later of: 

 

	 	(a)	The date on which Landlord’s Work has been completed (or would have been substantially completed except for Tenant Delay) except for items of work and adjustment
of equipment and fixtures which can be completed after occupancy has been taken without causing substantial interference with Tenant’s use of the Premises (i.e. so-called “punch list” items), or 


 

	 	(b)	The date when permission has been obtained from the applicable governmental authority, to the extent required by law, for occupancy by Tenant of the Premises for the
Permitted Use, unless the failure to obtain such permission is due to a Tenant Delay. 

 In the event of any
dispute as to the date on which Landlord’s Work has been completed as described in subsection 4.1(B)(2) above, the reasonable written determination of Landlord’s architect as to such date shall be deemed conclusive and binding on both
Landlord and Tenant, unless Tenant shall, within five (5) business days after receipt thereof, notify Landlord of its objection thereto and the specific reason(s) for such objection. Any disputes between the parties with respect to this Article
IV shall be submitted to arbitration in accordance with the provisions of Section 16.29 hereof. 
 (3) Incomplete
Work. Landlord shall complete as soon as conditions practically permit any incomplete items of Landlord’s Work, and Tenant shall cooperate with Landlord in providing access as may be required to complete such work in a normal manner.

 (4) Early Access by Tenant. Landlord shall permit Tenant access for installing Tenant’s trade fixtures,
cabling, furniture and telephone and computer systems in portions of the Premises prior to substantial completion at any time if it can be done without material interference with remaining work or with the maintenance of harmonious labor relations.
Any such access by Tenant shall be upon all of the terms and conditions of the Lease (other than the payment of Annual Fixed Rent) and shall be at Tenant’s sole risk, and Landlord shall not be responsible for any injury to persons or damage to
property resulting from such early access by Tenant. 
  

 11 








 (5) Prohibition on Access by Tenant Prior to Actual Substantial Completion.
If, prior to the date that the Premises are in fact actually substantially complete, the Premises are deemed to be substantially complete pursuant to the provisions of this Section 4.1 (i.e. and the Commencement Date has therefore
occurred), Tenant shall not (except with Landlord’s consent, which shall not be withheld if Landlord believes, in its reasonable judgment, that any such early access will not materially interfere with the completion of Landlord’s Work in a
timely fashion) be entitled to take possession of the Premises for the Permitted Use until the Premises are in fact actually substantially complete. 

(C) Tenant Delay. 

(1) Definition. A “Tenant Delay” shall be defined as the following: 

 

	 	(a)	Tenant’s failure timely to respond to any request from Landlord, Landlord’s architect, Landlord’s contractor and/or Landlord’s Construction
Representative or to timely provide all required Permit Documentation to Landlord within the applicable time periods set forth in this Article IV; 

  

	 	(b)	Tenant’s failure to pay the Tenant Plan Excess Costs in accordance with Section 4.5; 


 

	 	(c)	Any delay due to items of work (i) for which there is long lead time in obtaining the materials therefor or (ii) which are specially or specifically
manufactured, produced or milled for the work in or to the Premises and require additional time for receipt or installation (in either (i) or (ii) above, a “long lead time item”), but only with respect to items as to which
Landlord notifies Tenant in writing that such items are long lead time items. Landlord hereby notifies Tenant that with respect to Landlord’s Work prior to any Change Orders, the only item of work that may be a long lead time item is the
carpeting, depending on whether or not Tenant chooses a carpet that is in-stock locally; 

  

	 	(d)	Any delay due to changes, alterations or additions required or made by Tenant with respect to items not shown on the Plans and/or the Building Specifications including,
without limitation, Change Orders; or 

  

 12 









	 	(e)	Any other delays caused by Tenant, Tenant’s contractors, architects, engineers, or anyone else engaged by Tenant in connection with the preparation of the Premises
for Tenant’s occupancy, including, without limitation, utility companies and other entities furnishing communications, data processing or other service, equipment, or furniture. With respect to any Tenant Delay under this clause (e), no period
of time prior to the date that Landlord notifies Tenant of a Tenant Delay shall be considered to be a Tenant Delay. 


Landlord shall use reasonable efforts to notify Tenant of any delay described in subsections (a), (b) and (d) above promptly
after Landlord becomes aware of such delay, but such delay shall be considered to be a Tenant Delay immediately, without the requirement of Landlord first notifying Tenant thereof (provided, however, that with respect to delays described in
subsection (d) above, no period of time prior to the date that Landlord gives Tenant Landlord’s Change Order Response in accordance with the provisions of Section 4.1(a)(2) hereof or otherwise notifies Tenant of a Tenant Delay shall
be considered to be a Tenant Delay). 
 (2) Tenant Obligations with Respect to Tenant Delays. 

 

	 	(a)	Tenant covenants that no Tenant Delay shall delay commencement of the Term or the obligation to pay Annual Fixed Rent or Additional Rent, regardless of the reason for
such Tenant Delay or whether or not it is within the control of Tenant or any such employee. Landlord’s Work shall be deemed substantially completed as of the date when Landlord’s Work would have been substantially completed but for any
Tenant Delays, as determined by Landlord’s architect in the exercise of its good faith business judgement. 

  

	 	(b)	Tenant shall reimburse Landlord the amount, if any, by which the cost of Landlord’s Work is increased as the result of any Tenant Delay, as certified by
Landlord’s Architect. 

  

	 	(c)	Any amounts due from Tenant to Landlord under this Section 4.1(B)(2) shall be due and payable within thirty (30) days of billing therefor, and shall be
considered to be Additional Rent. Nothing contained in this Section 4.1 (B)(2) shall limit or qualify or prejudice any other covenants, agreements, terms, provisions and conditions contained in this Lease. 


 

	4.2	 OUTSIDE COMPLETION DATE. If Landlord shall have failed to actually substantially complete Landlord’s Work in the Premises described in the
Plans (as 


  

 13 









	 	
modified by Change Orders) on or before the Outside Completion Date as defined in Section 1.2 hereof (which date shall be extended automatically for such periods of time as Landlord is
prevented from proceeding with or completing the same by reason of Landlord’s Force Majeure as defined in Section 4.1 or any Tenant Delay, including a Tenant Delay in connection with a Change Order, provided that the Outside Completion
Date shall not be extended for more than thirty (30) days on account of Landlord’s Force Majeure), Tenant shall have the right to terminate this Lease by giving notice to Landlord of Tenant’s desire to do so before such completion;
and, upon the giving of such notice, the term of this Lease shall cease and come to an end without further liability or obligation on the part of either party unless, within thirty (30) days after receipt of such notice, Landlord substantially
completes Landlord’s Work; and such right of termination shall be Tenant’s sole and exclusive remedy for Landlord’s failure so to complete Landlord’s Work within such time. Landlord shall use reasonable efforts to keep Tenant
abreast of any extensions to the Outside Completion Date which Landlord believes are then in effect, and in any event from time to time upon written request of Tenant, Landlord shall notify Tenant as to the extensions to the Outside Completion Date
which Landlord believes are then in effect. 

  

	4.3	QUALITY AND PERFORMANCE OF WORK. All construction work required or permitted by this Lease shall be done in a good and workmanlike manner and in compliance with
all applicable laws, ordinances, rules, regulations, statutes, by-laws, court decisions, and orders and requirements of all public authorities (“Legal Requirements”) and all Insurance Requirements (as defined in Section 9.1 hereof).
All of Tenant’s work shall be coordinated with any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations. Each party may inspect the work of the other at reasonable times and shall promptly give
notice of observed defects. Each party authorizes the other to rely in connection with design and construction upon approval and other actions on the party’s behalf by any Construction Representative of the party named in Section 1.2 or
any person hereafter designated in substitution or addition by notice to the party relying. Except to the extent to which Tenant shall have given Landlord notice of respects in which Landlord has not performed Landlord’s construction
obligations under this Article IV (if any) not later than the end of the eleventh (11th) full calendar month next beginning after the Commencement Date, Tenant shall be deemed conclusively to have approved Landlord’s construction and shall have
no claim that Landlord has failed to perform any of Landlord’s obligations under this Article IV (if any). Landlord agrees to correct or repair at its expense items which are then incomplete or do not conform to the work contemplated under the
Plans and/or the Building Specifications and as to which, in either case, Tenant shall have given notice to Landlord, as aforesaid. 

  

	4.4	INTENTIONALLY OMITTED. 

  

 14 









	4.5	TENANT PLAN EXCESS COSTS. Notwithstanding anything contained in this Article IV to the contrary, it is understood and agreed that Tenant shall be fully
responsible for the costs of any items of work not shown on Exhibit B and/or Exhibit B-1 hereto (the “Tenant Plan Excess Costs”). To the extent, if any, that there are Tenant Plan Excess Costs, Tenant shall reimburse Landlord, as
Additional Rent, within thirty (30) days of billing therefor, from time to time during the performance of Landlord’s Work. 


ARTICLE V 

ANNUAL FIXED RENT 
  

	5.1	FIXED RENT. Tenant agrees to pay to Landlord, or as directed by Landlord at such place as Landlord shall from time to time designate by notice, (1) on the
Rent Commencement Date, and thereafter monthly, in advance, on the first day of each and every calendar month during the Original Lease Term, a sum equal to one-twelfth (1/12) of the Annual Fixed Rent specified in Section 1.2 hereof, and
(2) on the first day of each and every calendar month during each Extended Term (if exercised), a sum equal to one-twelfth of the Annual Fixed Rent as determined in Section 3.2 for such Extended Term. Until notice of some other designation
is given, Annual Fixed Rent and all other charges for which provision is herein made shall be paid by remittance to or to the order of Davenport Building L.P. at P.O. Box 10728, Silver Spring, MD 20914. 


Annual Fixed Rent for any partial month shall be paid by Tenant to Landlord at such rate on a pro rata basis, and, if the Rent
Commencement Date shall be other than the first day of a calendar month, the first payment of Annual Fixed Rent which Tenant shall make to Landlord shall be a payment equal to a proportionate part of such monthly Annual Fixed Rent for the partial
month from the Rent Commencement Date to the first day of the succeeding calendar month. 
 Additional Rent payable by Tenant on
a monthly basis, as elsewhere provided in this Lease, likewise shall be prorated, and the first payment on account thereof shall be determined in similar fashion and shall commence on the Rent Commencement Date and other provisions of this Lease
calling for monthly payments shall be read as incorporating this undertaking by Tenant. 
 The Annual Fixed Rent and all other
charges for which provision is made in this Lease shall be paid by Tenant to Landlord without setoff, deduction or abatement, except as otherwise expressly herein provided. 

 

 15 









	5.2	PREPAID RENT. Notwithstanding the provisions of Section 5.1 above, Tenant shall pay to Landlord the amount of Prepaid Rent, as set forth in
Section 1.2, which shall be credited by Landlord against Tenant’s obligations to pay Annual Fixed Rent hereunder as follows: 

  

				
	 Month of Lease
Term After the
Commencement
Date
	  	Amount of Credit to
Annual Fixed Rent
	6	  	$	8,255.00
	7	  	$	4,127.50
	12	  	$	8,255.00
	13	  	$	4,127.50

  

	5.3	UTILITY CHARGES. Tenant shall pay for all electricity or other utilities at the Premises directly to the utility providing the same. 


ARTICLE VI 

TAXES 
  

	6.1	DEFINITIONS. With reference to the real estate taxes referred to in this Article VI, it is agreed that terms used herein are defined as follows:


  

	 	(a)	“Tax Year” means the 12-month period beginning July 1 each year during the Lease Term or if the appropriate Governmental tax fiscal period shall begin on
any date other than July 1, such other date. 

  

	 	(b)	“Landlord’s Tax Expenses Allocable to the Premises” means the same proportion of Landlord’s Tax Expenses as Rentable Floor Area of Tenant’s
Premises bears to the Total Rentable Floor Area of the Building. 

  

	 	(c)	“Landlord’s Tax Expenses” with respect to any Tax Year means the aggregate “real estate taxes” (hereinafter defined) with respect to that Tax
Year, reduced by any net (i.e., net of the costs of obtaining the abatement or refund) abatement receipts with respect to that Tax Year. 

  

	 	(d)	 “Real estate taxes” means all taxes and special assessments of every kind and nature and user fees and other like fees assessed by any
Governmental authority on, or allocable to, the Building, which the Landlord shall be obligated to pay because of or in connection with the ownership, leasing or operation of the Building or Lot and reasonable expenses of any proceedings for
abatement of taxes. The amount of special taxes or special assessments to be included shall be limited to the amount of the installment (plus any interest other than penalty interest payable thereon) of such special tax or special assessment
required to be paid during the year in respect of which such taxes are being determined. There shall be 


  


 16 









	 	
excluded from such taxes all income, estate, succession, inheritance and transfer taxes; provided, however, that if at any time during the Lease Term the present system of ad valorem taxation of
real property shall be changed so that in lieu of, or in addition to, the whole or any part of the ad valorem tax on real property, there shall be assessed on Landlord a capital levy or other tax on the gross rents received with respect to the
Building Lot, or a Federal, State, County, Municipal, or other local income, franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect in the jurisdiction in which the Building is located) measured by or based, in
whole or in part, upon any such gross rents, then any and all of such taxes, assessments, levies or charges, to the extent so measured or based, shall be deemed to be included within the term “real estate taxes” but only to the extent that
the same would be payable if the Building, were the only property of Landlord. 

  

	 	(e)	“Base Taxes” means Landlord’s Tax Expenses (hereinbefore defined) for fiscal tax year 2004 (that is the period beginning July 1, 2003 and ending
June 30, 2004). 

  

	 	(f)	“Base Taxes Allocable to the Premises” means the same proportion of Base Taxes as the Rentable Floor Area of Tenant’s Premises bears to the Total
Rentable Floor Area of the Building. 

  

	 	(g)	If during the Lease Term the Tax Year is changed by applicable law to less than a full 12-month period, the Base Taxes and Base Taxes Allocable to the Premises shall
each be proportionately reduced. 

  

	6.2	 TENANT’S SHARE OF REAL ESTATE TAXES. If with respect to any full Tax Year or fraction of a Tax Year falling within the Lease Term after the
Rent Commencement Date Landlord’s Tax Expenses Allocable to the Premises for a full Tax Year exceed Base Taxes Allocable to the Premises or for any such fraction of a Tax Year exceed the corresponding fraction of Base Taxes Allocable to the
Premises (such amount being hereinafter referred to as the “Tax Excess”), then Tenant shall pay to Landlord, as Additional Rent, the amount of such Tax Excess. Payments by Tenant on account of the Tax Excess shall be made monthly at the
time and in the fashion herein provided for the payment of Annual Fixed Rent. The amount so to be paid to Landlord shall be an amount from time to time reasonably estimated by Landlord to be sufficient to provide Landlord, in the aggregate, a sum
equal to the Tax Excess, ten (10) days at least before the day on which tax payments by Landlord would become delinquent. Within a reasonable time after Landlord’s Tax Expenses Allocable to the Premises are determinable for the first such
Tax Year or fraction thereof and for each succeeding Tax Year or fraction thereof during the Lease Term, Landlord shall render Tenant a statement in reasonable detail certified by a representative of Landlord showing for the



  

 17 









	 	
preceding year or fraction thereof, as the case may be, real estate taxes allocated to the Building, abatements and refunds, if any, of any such taxes and assessments, expenditures incurred in
obtaining such abatement or refund, the amount of the Tax Excess, the amount thereof already paid by Tenant and the amount thereof overpaid by, or remaining due from, Tenant for the period covered by such statement. Within thirty (30) days
after the receipt of such statement, Tenant shall pay any sum remaining due. Any balance shown as due to Tenant shall be credited against Annual Fixed Rent next due, or refunded to Tenant if the Lease Term has then expired and Tenant has no further
obligation to Landlord. 

 To the extent that real estate taxes shall be payable to the taxing authority in
installments with respect to periods less than a Tax Year, the statement to be furnished by Landlord shall be rendered and payments made on account of such installments. 

 

	6.3	Any dispute between Landlord and Tenant relating to Article VI shall be submitted to arbitration in accordance with Section 16.31. 


ARTICLE VII 

LANDLORD’S REPAIRS AND SERVICES 

AND TENANT’S ESCALATION PAYMENTS 
  

	7.1	STRUCTURAL REPAIRS. Except for damage caused by fire or casualty and by eminent domain, Landlord shall, throughout the Lease Term, at Landlord’s sole cost
and expense, keep and maintain, or cause to be kept and maintained, in good order, condition and repair the following portions of the Building: the roof, the exterior and load bearing walls, the foundation, the structural columns and floor slabs and
other structural elements of the Building; provided however, that (subject to the provisions of Section 13.4 hereof) Tenant shall pay to Landlord, as Additional Rent, the cost of any and all such repairs which may be required as a result of
repairs, alterations, or installations made by Tenant or any subtenant, assignee, licensee or concessionaire of Tenant or any agent, servant, employee or contractor of any of them or to the extent of any loss, destruction or damage caused by the
omission or negligence of Tenant, any assignee or subtenant or any agent, servant, employee, customer, visitor or contractor of any of them. 

  

	7.2	 OTHER REPAIRS TO BE MADE BY LANDLORD. Except for damage caused by fire or casualty and by eminent domain, and except as may be otherwise
specifically provided in this Lease, Landlord agrees to keep and maintain, or cause to be kept and maintained, in good order, condition and repair the Common Areas and facilities of the Building, including heating, ventilating, air conditioning,
plumbing and other Building systems equipment servicing the Premises, except that Landlord shall in no event be responsible to Tenant for (a) the condition of glass in and about the Premises (other than for glass in exterior walls for which



  

 18 









	 	
Landlord shall be responsible unless the damage thereto is attributable to Tenant’s negligence or misuse, in which event the responsibility therefor shall be Tenant’s), or
(b) subject to the provisions of Section 13.4 hereof, any condition in the Premises or the Building caused by any act or neglect of Tenant or any agent, employee, contractor, assignee, subtenant, licensee, concessionaire or invitee of
Tenant. Without limitation, Landlord shall not be responsible to make any improvements or repairs to the Building or the Premises other than as expressly provided in Section 7.1 or in this Section 7.2, unless expressly otherwise provided
in this Lease. 

  

	7.3	SERVICES TO BE PROVIDED BY LANDLORD. In addition, and except as otherwise provided in this Lease, Landlord agrees to furnish services, utilities, facilities and
supplies as set forth in Exhibit C hereto equal in quality comparable to those customarily provided by landlords in similar office buildings in Cambridge. In addition, Landlord agrees to furnish, at Tenant’s expense, reasonable additional
Building operation services which are usual and customary in similar buildings in Cambridge, and such additional special services as may be mutually agreed upon by Landlord and Tenant, upon reasonable and equitable rates from time to time
established by Landlord. 

  

	7.4	OPERATING COSTS DEFINED. 


A. “Operating Expenses Allocable to the Premises” means the same proportion of the Operating Expenses for the Building (as
hereinafter defined) as Rentable Floor Area of the Premises bears to the Total Rentable Floor Area of the Building. 
 B.
“Base Operating Expenses” means Operating Expenses for the Building for calendar year 2004 (that is the period beginning January 1, 2004 and ending December 31, 2004). Base Operating Expenses shall not include market-wide cost
increases due to extraordinary circumstances which continue for a total of twenty-four (24) months or less (“Extraordinary Expenses”), including but not limited to, Landlord’s Force Majeure, boycotts, strikes, conservation
surcharges, embargoes or shortages. By way of example only, Base Operating Expenses would not include market-wide cost increases due to a carpenter’s strike in the Base Year which is settled prior to the date twenty-four (24) months after
the beginning of the strike, but would include a conservation surcharge imposed during the Base Year which continues for more than the next twenty-four (24) months. Since the determination of whether or not a particular item of costs in the
Base Year constitutes an Extraordinary Expense cannot be made until twenty-four (24) months later, all such costs shall be included in Base Operating Expenses initially. If Landlord determines that Base Operating Expenses have indeed included
one or more items that do constitute Extraordinary Expenses, then Landlord shall provide evidence thereof to Tenant, and such Extraordinary 
  

 19 








 
Expenses shall be excluded from Base Operating Expenses and shall also be excluded from Operating Expenses for the Building for the twenty-four (24) month period following the onset of such
Extraordinary Expense. 
 C. “Base Operating Expenses Allocable to the Premises” means the same proportion of Base
Operating Expenses as the Rentable Floor Area of Tenant’s Premises bears to the Total Rentable Floor Area of the Building. 

D. “Operating Expenses for the Building” means the cost of operation of the Building and Common Areas, including those incurred
in discharging the obligations under Sections 7.2 and 7.3. In addition, such costs shall exclude payments of debt service and any other mortgage charges, brokerage commissions, salaries of executives and owners not directly employed in the
management or operation of the Building, the general overhead and administrative expenses of the home office of Landlord or Landlord’s managing agent, and costs of special services rendered to tenants (including Tenant) for which a separate
charge is made, but shall include, without limitation: 
  

	 	(a)	compensation, wages and all fringe benefits, workmen’s compensation insurance premiums and payroll taxes paid to, for or with respect to all persons at or below
the level of property manager for their services in the operating, maintaining, managing, insuring or cleaning of the Building or the Common Areas (and to the extent that any such persons provide services to the Building and to other buildings, then
only the percentage of the foregoing amounts reasonably allocable to the Building shall be included); 

  

	 	(b)	payments under service contracts with independent contractors for operating, maintaining or cleaning of the Building or the Common Areas; 


 

	 	(c)	steam, water, sewer, gas, oil, electricity and telephone charges (excluding such utility charges separately chargeable to tenants for additional or separate services
and the cost of electricity or telephone service provided to leasable areas of the Building) and costs of maintaining letters of credit or other security as may be required by utility companies as a condition of providing such services;


  

	 	(d)	cost of maintenance, cleaning and repairs and replacements (other than repairs reimbursed from contractors under guarantees); 


 

	 	(e)	cost of snow removal and care of landscaping; 

  

 20 









	 	(f)	cost of building and cleaning supplies and equipment (including, without limitation, the costs of cellular telephones utilized by all persons at or below the level of
property manager in connection with the Building); 

  

	 	(g)	premiums for insurance carried with respect to the Building or Common Areas (including, without limitation, liability insurance, insurance against loss in case of fire
or casualty and of monthly installments of Annual Fixed Rent and any Additional Rent which may be due under this Lease and other leases of space in the Building for not more than twelve (12) months in the case of both Annual Fixed Rent and
Additional Rent and, if there be any first mortgage on the Building, including such insurance as may be required by the holder of such first mortgage); 

  

	 	(h)	management fees at competitive rates consistent with the type of occupancy and the services rendered; 


 

	 	(i)	Operating Expenses related to the operation of the Common Areas; 

  

	 	(j)	depreciation for capital improvements (x) to reduce Operating Expenses if Landlord reasonably shall have determined that the annual reduction in Operating Expenses
shall exceed depreciation therefor or (y) to comply with Legal Requirements not in existence on the Commencement Date (plus, in the case of both (x) and (y), an interest factor, reasonably determined by Landlord, as being the interest rate
then charged for long term mortgages by institutional lenders on like properties within the general locality in which the Building is located), and in the case of both (x) and (y) depreciation shall be determined by dividing the original
cost of such capital expenditure by the number of years of useful life of the capital item acquired, which useful life shall be determined reasonably by Landlord in accordance with generally accepted accounting principles and practices in effect at
the time of acquisition of the capital item; and 

  

	 	(k)	all other reasonable and necessary expenses paid in connection with the operating, cleaning and maintenance of the Building or the Common Areas and facilities and
properly chargeable against income. 

 Notwithstanding the foregoing, the following shall be excluded from
Operating Expenses for the Building: 
  

	 	(i)	The costs of the initial construction of the Building; 

  

	 	(ii)	All capital expenditures and depreciation, except as otherwise explicitly provided in this Section 7.4; 


 

 21 









	 	(iii)	Leasing fees or commissions, advertising and promotional expenses, legal fees, the cost of tenant improvements, build out allowances, moving expenses, assumption of
rent under existing leases and other concessions incurred in connection with leasing space in the Building; 

  

	 	(iv)	Interest on indebtedness, debt amortization, ground rent, and refinancing costs for any mortgage or ground lease of the Building, provided however, that the foregoing
shall not exclude the inclusion of the amortization and interest permitted to be included in Operating Expenses on account of capital improvements under Section 7.4(j) above; 


 

	 	(v)	Legal, auditing, consulting and professional fees and other costs (other than those legal, auditing, consulting and professional fees and other costs incurred in
connection with the normal and routine maintenance and operation of the Building), including, without limitation, those: (i) paid or incurred in connection with financings, refinancings or sales of any Landlord’s interest in the Building,
(ii) relating to specific disputes with tenants, and (iii) relating to any special reporting required by securities laws 

  

	 	(vi)	Costs incurred in performing work or furnishing services for any tenant (including Tenant), whether at such tenant’s or Landlord’s expense, to the extent that
such work or services is in excess of any work or service that Landlord is obligated to furnish to Tenant at Landlord’s expense (e.g., if Landlord agrees to provide extra cleaning to another tenant, the cost thereof would be excluded since
Landlord is not obligated to furnish extra cleaning to Tenant); 

  

	 	(vii)	The cost of any item or service to the extent reimbursed or reimbursable to Landlord by insurance maintained by Landlord (Tenant acknowledging that Landlord may include
such costs in Operating Expenses up to the amount of the deductible carried by Landlord under its casualty insurance), by any tenant, or by any third party; 


 

	 	(viii)	Any advertising, promotional or marketing expenses for the Building; 

  

	 	(ix)	The cost of any service or materials provided by any party related to Landlord, to the extent such costs exceed the reasonable cost for such service or materials absent
such relationship in buildings similar to the Building in the vicinity of the Building; 

  

	 	(x)	Payments for rented equipment leased for longer than thirty (30) days, the cost of which equipment would constitute a capital expenditure if the equipment were
purchased to the extent that such payments exceed the amount which could have been included in Operating Expenses had Landlord purchased such equipment rather than leasing such equipment; 


 

 22 









	 	(xi)	Penalties, damages, costs and interest for late payment or violations of any obligations of Landlord, including, without limitation, taxes, insurance, equipment leases
and other past due amounts and violations by Landlord of other tenant leases; 

  

	 	(xii)	The cost of testing, remediation or removal of “Hazardous Materials” (as defined in Section 11.2) in the Building required by “Hazardous Materials
Laws” (as defined in Section 11.2), provided however, that with respect to the testing, remediation or removal of any material or substance which, as of the Commencement Date was not considered, as a matter of law, to be a Hazardous
Material, but which is subsequently determined to be a Hazardous Material as a matter of law, the costs thereof shall be included in Operating Expenses, subject, however, to Section 7.4(j) to the extent that such cost is treated as a capital
expenditure. 

  

	 	(xiii) 	Wages, salaries, or other compensation paid to any executive employees above the grade of property manager at the Building, except that if any such employee performs a
service (i) for which said employee holds a professional qualification (e.g., a law degree or a CPA designation) and (ii) which would have been performed by an outside consultant and (iii) the cost of such consultant would be included
in Operating Expenses, then the compensation paid to such employee for performing such service shall be included in Operating Expenses, to the extent only that the cost of such service does not exceed competitive cost of such service had such
service been rendered by an outside consultant. 

  

	 	(xiv) 	Costs for sculpture, paintings or other objects of art. 

  

	 	(xv)	Charitable or political contributions. 

  

	 	(xvi) 	Rent for any office space occupied by Building management personnel to the extent the size or rental rate for such office space exceeds the size or fair market rental
value of office space occupied by management personnel of comparable buildings in the Cambridge/Boston market. 


In addition, the net (i.e. net of the reasonable costs of collection) amount recovered by Landlord under any warranty or service agreement
from any contractor or service provider shall be credited against Operating Expenses for the Building. 
  

 23 








 E. Notwithstanding the foregoing, in determining the amount of Operating Expenses for the
Building for any calendar year or portion thereof falling within the Lease Term (including the Base Year), if less than ninety-five percent (95%) of the Total Rentable Floor Area of the Building shall have been occupied by tenants at any time
during the period in question, then, at Landlord’s election for years other than the Base Year, but as a requirement for the Base Year, those components of Operating Expenses Allocable to the Premises that vary based on occupancy for such
period shall be adjusted to equal the amount such components of Operating Expenses Allocable to the Premises would have been for such period had occupancy been ninety-five percent (95%) throughout such period. 

 

	7.5	TENANT’S ESCALATION PAYMENTS. (A) If with respect to any calendar year falling within the Lease Term, or fraction of a calendar year falling within the
Lease Term at the beginning or end thereof, the Operating Expenses Allocable to the Premises (as defined in Section 7.4) for a full calendar year exceed Base Operating Expenses Allocable to the Premises (as defined in Section 7.4) or for
any such fraction of a calendar year exceed the corresponding fraction of Base Operating Expenses Allocable to the Premises (such amount being hereinafter referred to as the “Operating Cost Excess”), then Tenant shall pay to Landlord, as
Additional Rent, on or before the thirtieth (30th) day following receipt by Tenant of the statement referred to below in this Section 7.5, the amount of such excess. 


(B) Payments by Tenant on account of the Operating Cost Excess shall be made monthly at the time and in the fashion herein provided for
the payment of Annual Fixed Rent. The amount so to be paid to Landlord shall be an amount from time to time reasonably estimated by Landlord to be sufficient to cover, in the aggregate, a sum equal to the Operating Cost Excess for each calendar year
during the Lease Term. 
 (C) No later than one hundred twenty (120) days after the end of the first calendar year or
fraction thereof ending December 31 and of each succeeding calendar year during the Lease Term or fraction thereof at the end of the Lease Term, Landlord shall render Tenant a statement in reasonable detail and according to usual accounting
practices certified by a representative of Landlord, showing for the preceding calendar year or fraction thereof, as the case may be, the Operating Expenses for the Building and the Operating Expenses Allocable to the Premises. Said statement to be
rendered to Tenant also shall show for the preceding year or fraction thereof, as the case may be, the amounts already paid by Tenant on account of Operating Cost Excess and the amount of Operating Cost Excess remaining due from, or overpaid by,
Tenant for the year or other period covered by the statement. 
  

 24 








 If such statement shows a balance remaining due to Landlord, Tenant shall pay same to
Landlord on or before the thirtieth (30th) day following receipt by Tenant of said statement. Any balance shown as due to Tenant shall be credited against Annual Fixed Rent next due, or refunded to Tenant if the Lease Term has then expired and
Tenant has no further obligation to Landlord. 
 Any payment by Tenant for the Operating Cost Excess shall not be deemed to waive
any rights of Tenant to claim that the amount thereof was not determined in accordance with the provisions of this Lease. 
 (D)
Subject to the provisions of this paragraph, Tenant shall have the right, at Tenant’s cost and expense, to examine all documentation and calculations prepared in the determination of Operating Cost Excess: 

1. Tenant’s right to make such examination shall be conditioned on Tenant having paid the full amount of Operating Cost Excess
claimed by Landlord under this Section 7.5 within the time frames set forth in Section 7.5(C). 
 2. Such documentation
and calculation shall be made available to Tenant at the offices where Landlord keeps such records during normal business hours within a reasonable time after Landlord receives a written request from Tenant to make such examination. 

3. Tenant shall have the right to make such examination no more than once in respect of any period for which Landlord has given Tenant a
statement of the actual amount of Operating Expenses. 
 4. Any request for examination in respect of any calendar year may be
made no more than one hundred eighty (180) days after Landlord advises Tenant of the actual amount of Operating Expenses in respect of such calendar year and provides to Tenant the year-end statement required under Paragraph C of this
Section 7.5. 
 5. Such examination may be made only by an independent certified public accounting firm approved by
Landlord, which approval shall not be unreasonably withheld. Without limiting Landlord’s approval rights, Landlord may withhold its approval of any examiner of Tenant who is being paid by Tenant on a contingent fee basis. 

6. As a condition to performing any such examination, Tenant and its examiners shall be required to execute and deliver to Landlord an
agreement, in form reasonably acceptable to Landlord, agreeing to keep confidential any information which it discovers about Landlord or the Building in connection with such examination, provided however, that Tenant shall be permitted to share such

permitted subtenants so long as such subtenants execute and deliver to Landlord similar confidentiality agreements. Without limiting the foregoing, if Tenant uses any examiner which is other than
a nationally recognized accounting firm, Tenant’s examiner shall be required to agree that it will not represent any other tenant in the Building in connection with reviewing operating expenses for such tenant. 

7. Any claim for an adjustment based upon such the results of such examination must be made by Tenant, if at all, within sixty
(60) days after Landlord makes such documentation and calculation available to Tenant. 
 8. If the results of such
examination, as verified by Landlord’s accountant, show that Operating Cost Excess for the year in question was overstated by more than five percent (5%), then Landlord shall reimburse Tenant for the reasonable costs of performing such
examination. 
  

	7.6	NO DAMAGE. (A) Except for Landlord’s gross negligence or willful misconduct, and subject to the provisions of Section 2.2 hereof, Landlord shall
not be liable to Tenant for any compensation or reduction of rent by reason of inconvenience or annoyance or for loss of business arising from the necessity of Landlord or its agents entering the Premises for any purposes in this Lease authorized,
or for repairing the Premises or any portion of the Building or Common Areas however the necessity may occur. In case Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any services or performing any
other covenant or duty to be performed on Landlord’s part, by reason of any cause reasonably beyond Landlord’s control, including, without limitation, strike, lockout, breakdown, accident, order or regulation of or by any Governmental
authority, or failure of supply, or inability by the exercise of reasonable diligence to obtain supplies, parts or employees necessary to furnish such services, or because of war or other emergency, or for any cause due to any act or neglect of
Tenant or Tenant’s servants, agents, employees, licensees or any person claiming by, through or under Tenant, Landlord shall not be liable to Tenant therefor, nor, except as expressly otherwise provided in this Lease, shall Tenant be entitled
to any abatement or reduction of rent by reason thereof, nor shall the same give rise to a claim in Tenant’s favor that such failure constitutes actual or constructive, total or partial, eviction from the Premises. 


(B) Landlord reserves the right to stop any service or utility system, when necessary by reason of accident or emergency, or until
necessary repairs have been completed; provided, however, that in each instance of stoppage, Landlord shall exercise reasonable diligence to eliminate the cause thereof. Except in case of emergency repairs, Landlord will give Tenant reasonable
advance notice of any contemplated stoppage and will use diligent efforts to avoid unnecessary inconvenience to Tenant by reason thereof. 
  

 26 








 (C) Rent Abatement. Notwithstanding anything to the contrary in this Lease contained,
if due to (i) any repairs, alterations, replacements, or improvements made by Landlord, (ii) Landlord’s failure to make any repairs, alterations, or improvements required to be made by Landlord hereunder, or to provide any service
required to be provided by Landlord hereunder, or (iii) failure of electric supply, any portion of the Premises becomes untenantable so that for the Premises Untenantability Cure Period, as hereinafter defined, the continued operation in the
ordinary course of Tenant’s business is materially adversely affected, then, provided that Tenant ceases to use the affected portion of the Premises during the entirety of the Premises Untenantability Cure Period by reason of such
untenantability, and that such untenantability and Landlord’s inability to cure such condition is not caused by the fault or neglect of Tenant or Tenant’s agents, employees or contractors, Annual Fixed Rent and Operating Cost Excess and
Tax Excess shall thereafter be abated in proportion to such untenantability and its impact on the continued operation in the ordinary course of Tenant’s business until the day such condition is completely corrected. For the purposes hereof, the
“Premises Untenantability Cure Period” shall be defined as five (5) consecutive business days after Landlord’s receipt of written notice from Tenant of the condition causing untenantability in the Premises, provided however, that
the Premises Untenantability Cure Period shall be ten (10) consecutive business days after Landlord’s receipt of written notice from Tenant of such condition causing untenantability in the Premises if either the condition was caused by
causes beyond Landlord’s control or Landlord is unable to cure such condition as the result of causes beyond Landlord’s control. The provisions of this clause (C) shall not apply in the event of untenantability caused by fire or other
casualty, or taking (see Article XIV). 
  

	7.7	DISPUTES. Any disputes arising under this Article VII shall, at the election of either party, be submitted to arbitration in accordance with Section 16.31,
provided however, that pending the outcome of such arbitration, Landlord shall have the right to perform or take any actions which Landlord believes in good faith it is entitled to take under this Lease. 


ARTICLE VIII 

TENANT’S REPAIRS 
  

	8.1	 TENANT’S REPAIRS AND MAINTENANCE. Tenant covenants and agrees that, from and after the date that possession of the Premises is delivered to
Tenant and until the end of the Lease Term, Tenant will keep neat and clean and maintain in good order, condition and repair the Premises and every part thereof, excepting only reasonable wear and tear, those repairs for which Landlord is
responsible 


  

 27 









	 	
under the terms of Article VII of this Lease, damage by fire or casualty and as a consequence of the exercise of the power of eminent domain and, subject to the provisions of Section 13.4,
damage caused by the negligence or willful misconduct of Landlord, Landlord’s agents, employees or contractors. Tenant shall not permit or commit any waste, and, subject to the provisions of Section 13.4, Tenant shall be responsible for
the cost of repairs which may be made necessary by reason of damages to Common Areas or the Building by the negligence or willful misconduct of Tenant, Tenant’s agents, employees, contractors, sublessees, licensees, concessionaires or invitees.
Tenant shall maintain all its equipment, furniture and furnishings in good order and repair. 

 If repairs are
required to be made by Tenant pursuant to the terms hereof, Landlord may, upon reasonable advance notice, except that no notice shall be required in an emergency, demand that Tenant make the same forthwith, and if Tenant refuses or neglects to
commence such repairs and complete the same with reasonable dispatch after such demand, Landlord may (but shall not be required to do so) make or cause such repairs to be made and shall not be responsible to Tenant for any loss or damage that may
accrue to Tenant’s stock or business by reason thereof. If Landlord makes or causes such repairs to be made (after the expiration of any applicable notice or cure period, except in case of emergency), Tenant agrees that Tenant will forthwith on
demand, pay to Landlord as Additional Rent the cost thereof together with interest thereon at the rate specified in Section 16.21, and if Tenant shall default in such payment, Landlord shall have the remedies provided for non-payment of rent or
other charges payable hereunder. 
 ARTICLE IX 

ALTERATIONS 
  

	9.1	LANDLORD’S APPROVAL. Tenant covenants and agrees not to make alterations, additions or improvements to the Premises, whether before or during the Lease
Term, except in accordance with plans and specifications therefor first approved by Landlord in writing, which approval shall not be unreasonably withheld or delayed. However, Landlord’s determination of matters relating to aesthetic issues
relating to alterations, additions or improvements which are visible outside the Premises shall be in Landlord’s sole discretion. Without limiting such standard, Landlord shall not be deemed unreasonable: 


(a) for withholding approval of any alterations, additions or improvements which (i) in Landlord’s reasonable opinion might
materially adversely affect any structural or exterior element of the Building, any area or element outside of the Premises or any facility or base building mechanical system serving any area of the Building outside of the Premises, or
(ii) involve or affect the exterior design, size, height or other 
  

 28 








 
exterior dimensions of the Building, or (iii) enlarge the Rentable Floor Area of the Premises, or (iv) are not at least equal in quality, in Landlord’s reasonable judgment, with
Landlord’s Work, as defined in Section 4.1 hereof. 
 (b) for making its approval conditional on Tenant’s
agreement to restore the Premises to its condition prior to such alteration, addition, or improvement at the expiration or earlier termination of the Lease Term. Landlord agrees, upon written request of Tenant made at the time Tenant requests
Landlord’s approval, to indicate to Tenant whether or not it will require restoration as aforesaid at the expiration or earlier termination of the term hereof. 

Landlord’s review and approval of any such plans and specifications or under Section 4.1 and consent to perform work described
therein shall not be deemed an agreement by Landlord that such plans, specifications and work conform with applicable Legal Requirements and requirements of insurers of the Building (herein called “Insurance Requirements”) nor deemed a
waiver of Tenant’s obligations under this Lease with respect to applicable Legal Requirements and Insurance Requirements nor impose any liability or obligation upon Landlord with respect to the completeness, design sufficiency or compliance of
such plans, specifications and work with applicable Legal Requirements and Insurance Requirements. 
  

	9.1.1	CERTAIN ALTERATIONS. Notwithstanding the terms of Section 9.1, Tenant shall have the right, without obtaining the prior consent of Landlord, but upon at
least five (5) business days’ prior written notice to Landlord, to make alterations, additions or improvements to the Premises (“Permitted Alterations”) where: 


 

	 	(i)	the same are within the interior of the Premises within the Building, and do not affect the exterior of the Premises and the Building; 


 

	 	(ii)	the same do not affect the roof, any structural element of the Building, the mechanical, electrical, plumbing, heating, ventilating, air-conditioning and fire
protection systems of the Building; 

  

	 	(iii)	the aggregate cost of all Permitted Alterations does not exceed $25,000.00 in any twelve month period; and 


 

	 	(iv)	Tenant shall comply with the provisions of this Lease and if such work increases the cost of insurance or taxes or of services, Tenant shall pay for any such increase
in cost. 

  

 29 









	9.2	CONFORMITY OF WORK. Tenant covenants and agrees that any alterations, additions, improvements or installations made by it to or upon the Premises shall be done
in a good and workmanlike manner and in compliance with all applicable Legal Requirements and Insurance Requirements now or hereafter in force, that materials of first and otherwise good quality shall be employed therein, that the structure of the
Building shall not be endangered or impaired thereby and that the Premises shall not be diminished in value thereby. 

  

	9.3	PERFORMANCE OF WORK, GOVERNMENTAL PERMITS AND INSURANCE. All of Tenant’s alterations and additions and installation of furnishings shall be coordinated with
any work being performed by or for Landlord and in such manner as to maintain harmonious labor relations and not to damage the Building or Common Areas or interfere with Building construction or operation and, except for installation of furnishings
and voice and data cabling, shall be performed by Landlord’s general contractor or by contractors or workmen first approved by Landlord, such approval not to be unreasonably withheld. Except for work by Landlord’s general contractor,
Tenant shall procure all necessary governmental permits before making any repairs, alterations, other improvements or installations. Subject to the provisions of Section 13.4, Tenant agrees to save harmless and indemnify Landlord from any and
all injury, loss, claims or damage to any person or property occasioned by or arising out of the doing of any such work whether the same be performed prior to or during the Term of this Lease, except to the extent caused by the negligence or willful
misconduct of Landlord, its agents, contractors or employees. At Landlord’s election, where the cost of such work exceeds $75,000.00 in any one instance, Tenant shall cause its contractor to maintain a payment and performance bond in such
amount and with such companies as Landlord shall reasonably approve. In addition, Tenant shall cause each contractor to carry workmen’s compensation insurance in statutory amounts covering the employees of all contractors and subcontractors,
and commercial general liability insurance or comprehensive general liability insurance with a broad form comprehensive liability endorsement with such limits as Landlord may require reasonably from time to time during the Term of this Lease, but in
no event less than the minimum amount of commercial general liability insurance or comprehensive general liability insurance Tenant is required to maintain as set forth in Section 1.2 hereof and as the same may be modified as provided in
Section 13.2 hereof (all such insurance to be written in companies approved reasonably by Landlord and insuring Landlord, Landlord’s managing agent and Tenant as additional insureds as well as contractors) and to deliver to Landlord
certificates of all such insurance. 

  

	9.4	LIENS. Tenant covenants and agrees to pay promptly when due the entire cost of any work done on the Premises by Tenant, its agents, employees or contractors, and
not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to the Premises or the Building or the Common Areas and immediately to discharge or bond over any such liens which may so attach.


  

 30 









	9.5	NATURE OF ALTERATIONS. All work, construction, repairs, alterations, other improvements or installations made to or upon the Premises (including, but not limited
to, Landlord’s Work, shall become part of the Premises and shall become the property of Landlord and remain upon and be surrendered with the Premises as a part thereof upon the expiration or earlier termination of the Lease Term, except as
follows: 

  

	 	(a)	All trade fixtures and business equipment (including any furniture systems) whether by law deemed to be a part of the realty or not, installed at any time or times by
Tenant or any person claiming under Tenant shall remain the property of Tenant or persons claiming under Tenant and may be removed by Tenant or any person claiming under Tenant at any time or times during the Lease Term or any occupancy by Tenant
thereafter and shall be removed by Tenant at the expiration or earlier termination of the Lease Term if so requested by Landlord. Tenant shall repair any damage to the Premises occasioned by the removal by Tenant or any person claiming under Tenant
of any such property from the Premises. 

  

	 	(b)	At the expiration or earlier termination of the Lease Term, unless otherwise agreed in writing by Landlord, Tenant shall remove (i) any wiring, cables or other
installations appurtenant thereto for Tenant’s computer, telephone and other communication systems and equipment in any portion of the Building outside of the Premises, including all risers, and (ii) any alterations, additions and
improvements (excluding Landlord’s Work) made with Landlord’s consent during the Lease Term for which such removal was made a condition of such consent under Section 9.1(A)(b). Upon such removal Tenant shall restore the Premises to their
condition prior to such alterations, additions and improvements and repair any damage occasioned by such removal and restoration. 

  

	 	(c)	If Tenant shall make any alterations, additions or improvements to the Premises for which Landlord’s approval is required under Section 9.1 without obtaining
such approval, then at Landlord’s request at any time during the Lease Term, and at any event at the expiration or earlier termination of the Lease Term, Tenant shall remove such alterations, additions and improvements and restore the Premises
to their condition prior to same and repair any damage occasioned by such removal and restoration. Nothing herein shall be deemed to be a consent to Tenant to make any such alterations, additions or improvements, the provisions of Section 9.1
being applicable to any such work. 

  

 31 









	9.6	INCREASES IN TAXES. Tenant shall pay, as Additional Rent, one hundred percent (100%) of any increase in real estate taxes on the Building which shall, at
any time after the Commencement Date, result from alterations, additions or improvements to the Premises made by Tenant if the taxing authority specifically determines such increase results from such alterations, additions or improvements made by
Tenant. 

 ARTICLE X 

PARKING 
  

	10.1	PARKING PRIVILEGES. Commencing as of the Commencement Date, Landlord shall provide to Tenant monthly parking privileges in the City of Cambridge Garage located
adjacent to the Building at Thorndike Street, Cambridge (the “Garage”) for three (3) passenger automobiles for the parking of motor vehicles in unreserved stalls in the Garage by Tenant’s employees, invitees and clients, and for
the temporary storage of cars, all subject to the remaining provisions of this Section 10.1. Tenant acknowledges that Landlord does not own or control the Garage, but rather leases spaces therein pursuant to a long-term lease agreement with the
City of Cambridge (the “Garage Lease”). Tenant acknowledges that Tenant’s parking privileges as aforesaid are a sublicense of Landlord’s rights under the Garage Lease, and are subject and subordinate in all respects to the Garage
Lease. Without limiting the foregoing, a copy of the use provision of the Garage Lease is attached hereto as Exhibit L. Landlord makes no representation or warranty as to whether or not Tenant’s proposed use of the Garage other than for
employee parking complies with the use provisions of the Garage Lease and/or with applicable law. If at any time the City of Cambridge or any other authority having jurisdiction objects to Tenant’s use of the Garage for anything other than
parking by Tenant’s employees (“Non-Employee Use”) as not being in accordance with applicable law or the terms of the Garage Lease, Tenant shall immediately cease such Non-Employee Use. Tenant specifically acknowledges that Landlord
shall have no obligation to defend Tenant’s Non- Employee Use or otherwise contest any such objection, and that Tenant shall have no claim for diminution of rent or other remedy at law, in equity, or under this Lease for Tenant’s loss of
the use of the Garage for the Non-Employee Use. Landlord agrees that, except for causes beyond Landlord’s control (including, without limitation, casualty, condemnation and the termination of the Garage Lease), Tenant shall have the right to
use the aforesaid three (3) parking privileges throughout the Term of the Lease for the parking of motor vehicles in unreserved stalls in the Garage by Tenant’s employees. 


 

	10.2	 PARKING CHARGES. Tenant shall pay Landlord for such parking privileges at the monthly rates from time to time charged to Landlord under the
Garage Lease. Such monthly parking charges for parking privileges shall constitute Additional Rent and shall be payable monthly as directed by Landlord upon billing therefor 



 

 32 









	 	
by Landlord. Tenant acknowledges that said monthly charges to be paid under this Section are for the use by the Tenant of the parking privileges referred to herein, and not for any other service.
The monthly charge for each parking privilege is currently One Hundred Sixty-Five Dollars ($165.00), but said charge is subject to change without notice. 

  

	10.3	GARAGE OPERATION. Unless otherwise determined by Landlord or the operator of such garage (the “Garage Operator”), the Garage is to be operated on a
self-parking basis, and Tenant shall be obligated to park and remove its own automobiles, and Tenant’s parking shall be on an unreserved basis, Tenant having the right to park in any available stalls. Tenant’s access and use privileges
with respect to the Garage shall be in accordance with the Garage Lease and with regulations of uniform applicability to the users of the Garage from time to time established by the Landlord or the Garage Operator. Tenant acknowledges that the
Garage Lease only requires the Garage to be open eighteen (18) hours per day, seven (7) days per week, and that the Garage Lease does not specify which eighteen (18) hours in any twenty-four (24) hour period the Garage is
required to be open. Tenant shall supply Landlord or, if directed by Landlord, the Garage Operator with an identification roster listing the name of the employee and the make, color and registration number of the vehicle to which a parking right has
been assigned, and shall provide a revised roster to Landlord indicating changes thereto promptly upon Landlord’s request. The Garage owner reserves the right to have any automobile found parked in the Garage during normal business hours
without appropriate identification towed at said automobile owner’s expense. The parking privileges granted herein are non-transferable (other than to a permitted assignee or subtenant pursuant to the applicable provisions of Article XII
hereof). The Garage Operator may institute a so-called valet or attendant-managed parking program for the Garage, and in such event Tenant shall cooperate in all respects with such program. 


 

	10.4	LIMITATIONS. Tenant agrees that it and all persons claiming by, through and under it, shall at all times abide by all reasonable rules and regulations
promulgated by Landlord or the Garage Operator with respect to the use of the Garage. Except to the extent of gross negligence or willful acts, Landlord assumes no responsibility whatsoever for loss or damage due to fire or theft or otherwise to any
automobile or to any personal property therein, however caused, and Tenant agrees, upon request from the Landlord, from time to time, to notify its officers, employees and agents then using any of the parking privileges provided for herein, of such
limitation of liability. Tenant further acknowledges and agrees that a license only is hereby granted, and no bailment is intended or shall be created. 


 

 33

invalidate or increase the premiums for any insurance on the Building or its contents or liable to render necessary any alteration or addition to the Building. 


(B) Further, (i) Tenant shall not, nor shall Tenant permit its employees, invitees, agents, independent contractors, contractors,
assignees or subtenants to, keep, maintain, store or dispose of (into the sewage or waste disposal system or otherwise) (except for standard office and cleaning supplies stored, handled and disposed of in accordance with all applicable laws) or
engage in any activity which might produce or generate any substance which is or may hereafter be classified as a hazardous material, waste or substance (collectively “Hazardous Materials”), under federal, state or local laws, rules and
regulations, including, without limitation, 42 U.S.C. Section 6901 et seq., 42 U.S.C. Section 9601 et seq., 42 U.S.C. Section 2601 et seq., 49 U.S.C. Section 1802 et seq. and Massachusetts General Laws, Chapter 21E and the rules

obligations hereunder accruing from and after the termination date, but Tenant shall remain fully liable for all obligations hereunder accruing before the termination date. 

 

	11.3	Not to obstruct in any manner any portion of the Building not hereby leased or any portion thereof or of the Common Areas used by Tenant in common with others; not

Section 16.32) now or hereafter made by Landlord, of which Tenant has been given notice, for the care and use of the Building and the Common Areas and their facilities and approaches, but Landlord shall not be liable to Tenant for the failure

to do any work so required because of such use, it being understood that the foregoing provisions shall not be construed to broaden in any way Tenant’s Permitted Use. 


 

	11.5	Not to place a load upon any floor in the Premises exceeding the lesser of (i) the maximum load permitted by law, and (ii) the maximum load for which such
floor was designed; and not to move any safe, vault or other heavy equipment in, about or out of the Premises except in such manner and at such time as Landlord shall in each instance authorize. Tenant’s business machines and mechanical
equipment shall be placed and maintained by Tenant at Tenant’s expense in settings sufficient to absorb and prevent vibration or noise that may be transmitted to the Building structure or to any other space in the Building.


  

 35 









	11.6	To pay promptly when due all taxes which may be imposed upon personal property (including, without limitation, fixtures and equipment) in the Premises to whomever

occupancy of the Premises, the losing party shall, upon demand, reimburse the prevailing party for its reasonable costs of prosecuting and/or defending such proceeding (including, without limitation, reasonable attorneys fees), provided however,
that with respect to arbitration, the losing party shall only be obligated to reimburse the prevailing party for attorneys’ fees if such fees are awarded by the arbitrators). 


 

	11.8	Not to knowingly do or knowingly permit anything to be done in or upon the Premises, or bring in anything or keep anything therein, which shall increase the rate of
insurance on the Premises or on the Building above the standard rate applicable to premises being occupied for the use to which Tenant has agreed to devote the Premises; and Tenant further agrees that, in the event that Tenant shall do any of the
foregoing, Tenant will promptly pay to Landlord, on demand, any such increase resulting therefrom, which shall be due and payable as Additional Rent hereunder. 


 

	11.9	To comply with all applicable Legal Requirements now or hereafter in force which shall impose a duty on Landlord or Tenant relating to or as a result of the use or
occupancy of the Premises; provided that Tenant shall not be required to make any alterations or additions to the structure, roof, exterior and load bearing walls, foundation, structural floor slabs and other structural elements of the Premises or
the Building or to utility or Building service equipment unless the same are required by such Legal Requirements as a result of or in connection with (i) Tenant’s use or occupancy of the Premises beyond normal office use of space of this
kind, or (ii) modifications or alterations made by or for Tenant to the Premises or any such utility or Building service equipment (excluding, however, Landlord’s Work). Tenant shall promptly pay all fines, penalties and damages that may
arise out of or be imposed because of its failure to comply with the provisions of this Section 11.9. Landlord, subject to inclusion of the cost of compliance as Operating Expenses of the Building to the extent permitted by the provisions of
Section 7.4 of this Lease, shall comply with (i) all Laws which relate to the structure of the Building, unless the need for such compliance arises from Tenant’s particular use of the Premises, and (ii) all other Laws applicable

provisions of its lease with Landlord. 

  

 36 









	11.10 	Tenant shall not use the words “Davenport Building” other than as part of the business address of Tenant and then only in such manner as will not appear to be

ARTICLE XII 

ASSIGNMENT AND SUBLETTING 
  

	12.1	RESTRICTIONS ON TRANSFER. Except as otherwise expressly provided herein, Tenant covenants and agrees that it shall not assign, mortgage, pledge, hypothecate or
otherwise transfer this Lease and/or Tenant’s interest in this Lease or sublet (which term, without limitation, shall include granting of concessions, licenses or the like) the whole or any part of the Premises. Any assignment, mortgage,
pledge, hypothecation, transfer or subletting not expressly permitted in or consented to by Landlord under this Article XII shall be void, ab initio; shall be of no force and effect; and shall confer no rights on or in favor of third parties. In
addition, Landlord shall be entitled to seek specific performance of, and other equitable relief with respect to, the provisions hereof. 

  

	12.2	EXCEPTIONS. Notwithstanding the foregoing provisions of Section 12.1 above and the provisions of Section 12.3,12.4 and 12.6 below (all of which shall
be inapplicable to a transfer pursuant to this Section 12.2), but subject to the provisions of Sections 12.5 and 12.7, Tenant shall have the right to assign this Lease or to sublet the Premises (in whole or in part) to any controlling
entity of Tenant or to any entity controlled by Tenant or to any entity under common control with Tenant (such parent or subsidiary entity or entity under common control with Tenant being hereinafter called a “Tenant Affiliate”) or to any
corporation, limited liability partnership or limited liability company or other entity into which Tenant may be converted or with which it may merge, or to any entity purchasing all or substantially all of Tenant’s assets or voting stock
(each, a “Permitted Tenant Successor”), provided that in the case of a Permitted Tenant Successor, the entity to which this Lease is so assigned or which so sublets the Premises has a net worth (e.g. assets on a pro forma basis using
generally accepted accounting principles consistently applied and using the most recent financial statements) which is the same as or better than the Tenant as of the date of this Lease. If any Tenant Affiliate to which this Lease is assigned or the
Premises sublet (in whole or in part) shall cease to be such a Tenant Affiliate, and if such cessation was contemplated at the time of the assignment or subletting, such cessation shall be considered an assignment or subletting requiring
Landlord’s consent. 

  

 37 









	12.3	LANDLORD’S TERMINATION RIGHT. Notwithstanding the provisions of Section 12.1 above, but subject to the exceptions set forth in Section 12.2 above,
in the event Tenant desires to assign this Lease or to sublet the whole or any part of the Premises, Tenant shall give Landlord a Recapture Offer, as hereinafter defined. 


For the purposes hereof a “Recapture Offer” shall be defined as a notice in writing from Tenant to Landlord which: 

 

	 	(a)	States that Tenant desires to sublet the Premises, or a portion thereof, or to assign its interest in this Lease. 


 

	 	(b)	Identifies the affected portion of the Premises (“Recapture Premises”). 


 

	 	(c)	Identifies the period of time (“Recapture Period”) during which Tenant proposes to sublet the Recapture Premises or to assign its interest in the Lease.


  

	 	(d)	Intentionally omitted. 

  

	 	(e)	Offers to Landlord to terminate the Lease in respect of the Recapture Premises (in the case of a proposed assignment of Tenant’s interest in the Lease or a
subletting for the remainder of the Term of the Lease) or to suspend the Term of the Lease pro tanto in respect of the Recapture Period (i.e. the Term of the Lease in respect of the Recapture Premises shall be terminated during the Recapture
Period and Tenant’s rental obligations shall be reduced in proportion to the ratio of the Rentable Floor Area of the Recapture Premises to the Rentable Floor Area of the Premises then demised to Tenant and at the expiration of the Recapture
Period the Recapture Premises will be returned to Tenant under the terms of the Lease). 

 Landlord shall have
thirty (30) days from Landlord’s receipt of the Recapture Offer to accept a Recapture Offer (the “Acceptance Period”). In the event that Landlord shall not timely exercise its termination or suspension rights as aforesaid, or
shall fail to give any or timely notice pursuant to this Section, the provisions of Sections 12.4-12.7 shall be applicable. This Section 12.3 shall not be applicable to an assignment or sublease pursuant to Section 12.2.

	12.4	CONSENT OF LANDLORD. Notwithstanding the provisions of Section 12.1 above, but subject to the provisions of this Section 12.4 and the provisions of
Sections 12.5, 12.6 and 12.7 below, in the event that Landlord shall not have exercised the termination or suspension right as set forth in Section 12.3, or shall have failed to give any or timely notice under Section 12.3, then for a
period of one hundred eighty (180) days (i) after the receipt of Landlord’s notice stating that Landlord does not elect the termination right, or (ii) after the expiration of the Acceptance Period referred to in
Section 12.3, in the event Landlord shall not give any or timely notice under Section 12.3 as the case may be, Tenant shall have the right to assign this Lease or sublet the whole or any part of the Premises in accordance with
Tenant’s Notice (as defined in Section 12.5) provided that, in each instance, Tenant first obtains the express prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed. Without limiting the foregoing
standard, Landlord shall not be deemed to be unreasonably withholding its consent to such a proposed assignment or subleasing if: 

  

	 	(a)	the proposed assignee or subtenant is a tenant in the Building, or is (or within the previous sixty (60) days has been) in active negotiation with Landlord for
premises in the Building or is not of a character consistent with the operation of a first class office building (by way of example Landlord shall not be deemed to be unreasonably withholding its consent to an assignment or subleasing to any
governmental or quasi-governmental agency), or 

  

	 	(b)	the proposed assignee or subtenant is not of good character and reputation, or 


 

	 	(c)	the proposed assignee or subtenant does not possess adequate financial capability to perform the Tenant obligations as and when due or required, or


  

	 	(d)	the assignee or subtenant proposes to use the Premises (or part thereof) for a purpose other than the purpose for which the Premises may be used as stated in
Section 1.2 hereof, or 

  

	 	(e)	the character of the business to be conducted or the proposed use of the Premises by the proposed subtenant or assignee shall (i) be likely to increase Operating
Expenses for the Building beyond that which Landlord now incurs for use by Tenant; (ii) be likely to increase the burden on elevators or other Building systems or equipment over the burden prior to such proposed subletting or assignment; or
(iii) violate or be likely to violate any provisions or restrictions contained herein relating to the use or occupancy of the Premises, or 

  

	 	(f)	there shall be existing an Event of Default (defined in Section 15.1). 

  


 39 









	12.5	TENANT’S NOTICE. Tenant shall give Landlord notice of any proposed sublease or assignment, and said notice (“Tenant’s Notice”) shall specify
the provisions of the proposed assignment or subletting, including (a) the name and address of the proposed assignee or subtenant, (b) in the case of a proposed assignment or subletting subject to the provisions of Section 12.4, such
information as to the proposed assignee’s or proposed subtenant’s net worth and financial capability and standing as may reasonably be required for Landlord to make the determination referred to in Section 12.4 above (provided,
however, that Landlord shall hold such information confidential, having the right to release same to its officers, accountants, attorneys and mortgage lenders on a confidential basis), (c) all of the terms and provisions upon which the proposed
assignment or subletting is to be made, (d) in the case of a proposed assignment or subletting subject to the provisions of Section 12.4, all other information necessary to make the determination referred to in Section 12.4 above and
(e) in the case of a proposed assignment or subletting pursuant to Section 12.2 above, such information as may be reasonably required by Landlord to determine that such proposed assignment or subletting complies with the requirements of
said Section 12.2. With respect to an assignment or subletting under Section 12.2 above, Tenant’s Notice may be given within ten (10) days following such transaction, but the foregoing shall not expand the parameters of what does
or does not meet the requirements of said Section 12.2. 

 Landlord shall notify Tenant within ten
(10) business days of its receipt of Tenant’s Notice as aforesaid whether or not Landlord consents to the proposed assignment or subletting. If Landlord does consent to the proposed assignment or subletting, as the case may be, then, in
such event, Tenant may thereafter sublease the whole or any part of the Premises or assign pursuant to Tenant’s Notice, as given hereunder; provided, however, that if such assignment or sublease shall not be executed and delivered to Landlord
within one hundred eighty (180) days after the date of Landlord’s consent, the consent shall be deemed null and void and the provisions of Section 12.3 shall again be applicable. 

 

	12.6	PROFIT ON SUBLEASING OR ASSIGNMENT. In addition, in the case of any assignment or subleasing as to which Landlord may consent (other than an assignment or
subletting permitted under Section 12.2 hereof) such consent shall be upon the express and further condition, covenant and agreement, and Tenant hereby covenants and agrees that, in addition to the Annual Fixed Rent, Additional Rent and other
charges to be paid pursuant to this Lease, fifty percent (50%) of the “Assignment/Sublease Profits” (hereinafter defined), if any shall be paid to Landlord. 


The “Assignment/Sublease Profits” shall be the excess, if any, of (a) the “Assignment/Sublease Net Revenues” as
hereinafter defined over (b) the Annual Fixed Rent, Additional Rent and other charges provided in this Lease (provided, 
  


 40 








 
however, that for the purpose of calculating the Assignment/Sublease Profits in the case of a sublease, appropriate proportions in the applicable Annual Fixed Rent, Additional Rent and other
charges under this Lease shall be made based on the percentage of the Premises subleased and on the terms of the sublease). The “Assignment/Sublease Net Revenues” shall be the fixed rent, additional rent and all other charges and sums
payable either initially or over the term of the sublease or assignment plus all other profits and increases to be derived by Tenant as a result of such subletting or assignment, less the reasonable costs of Tenant incurred in such subleasing or
assignment (the definition of which shall include but not necessarily be limited to rent concessions, brokerage commissions and alteration allowances) as set forth in a statement certified by an appropriate officer of Tenant and delivered to
Landlord within thirty (30) days of the full execution of the sublease or assignment document, amortized over the term of the sublease or assignment. 

All payments of the Assignment/Sublease Profits due Landlord shall be made within ten (10) days of receipt of same by Tenant.

  

	12.7	ADDITIONAL CONDITIONS. 


(A) It shall be a condition of the validity of any assignment permitted under Section 12.2 above, or consented to under
Section 12.4 above, that both Tenant and the assignee agree directly with Landlord in a separate written instrument reasonably satisfactory to Landlord which contains terms and provisions reasonably required by Landlord, including, without
limitation, the agreement of the assignee to be bound by all the obligations of the Tenant hereunder, including, without limitation, the obligation to pay the Annual Fixed Rent, Additional Rent, and other amounts provided for under this Lease,
including the provisions of Sections 12.1 through 12.7 hereof, but such assignment shall not relieve the Tenant named herein of any of the obligations of the Tenant hereunder, Tenant shall remain fully and primarily liable therefor and the liability
of Tenant and such assignee shall be joint and several. It shall be a condition of the validity of any sublease of right under Section 12.2 above, or consented to under Section 12.4 above, that the sublease provide (with Landlord
specifically stated to be a third-party beneficiary of such provision) that the subtenant: (i) will not breach any of Tenant’s obligations under the Lease with respect to the subleased premises, (ii) will obtain any liability
insurance covering the same risks, in the same amounts, and covering the same parties which Tenant is required to obtain and maintain pursuant to Article 13, (iii) shall, prior to entering the Premises, deliver to Landlord a certificate of such
liability insurance, and (iv) agrees that any sub-sublease by such subtenant and any assignment of such subtenant’s interest in its sublease shall be considered to be a sublease by Tenant, for the purposes of this Article 12 and shall be
subject and subordinate to all of the provisions of this Article 12. Further, and notwithstanding the foregoing, the provisions hereof shall 

 

 41 








 
not constitute a recognition of the assignment or the assignee thereunder or the sublease or the subtenant thereunder, as the case may be, and at Landlord’s option, upon the termination or
expiration of the Lease (whether such termination is based upon a cause beyond Tenant’s control a default of Tenant, the agreement of Tenant and Landlord or any other reason), the assignment or sublease shall be terminated. 

(B) As Additional Rent, Tenant shall reimburse Landlord promptly for reasonable out of pocket legal and other expenses incurred by
Landlord in connection with any request by Tenant for consent to assignment or subletting, not to exceed Two Thousand Dollars ($2,000.00) for each such request. 

(C) If the Premises or any part thereof be sublet or occupied by anyone other than Tenant, Landlord may upon prior notice to Tenant, at
any time after an Event of Default hereunder and from time to time thereafter while such Event of Default remains uncured, collect all of the rent and other charges due under such sublease from the sublessee or occupant and apply the net amount
collected to the Annual Fixed Rent, Additional Rent and other charges herein reserved, but no such subletting, occupancy or collection shall be deemed a waiver of this covenant, or a waiver of the provisions of Sections 12.1 through 12.7 hereof, or
the acceptance of the sublessee or occupant as a tenant or a release of Tenant from the further performance by Tenant of covenants on the part of Tenant herein contained, the Tenant herein named to remain primarily liable under this Lease.

 (D) No assignment or subletting under any of the provisions of Sections 12.2 or 12.4 shall in any way be construed to relieve
Tenant from obtaining the express consent in writing of Landlord to any further assignment or subletting. 
 (E) Without limiting
Tenant’s obligations under Article IX, Tenant shall be responsible, at Tenant’s sole cost and expense, for performing all work necessary to comply with Legal Requirements and Insurance Requirements in connection with any assignment or
subletting hereunder including, without limitation, any alterations performed in connection with such assignment or subletting, except that the foregoing shall not apply so as, solely as a result of such assignment or subletting, to transfer an
obligation from Landlord to Tenant which otherwise would have been Landlord’s obligation under the terms of this Lease. 

ARTICLE XIII 

INDEMNITY AND LIABILITY INSURANCE 
  

	13.1	 TENANT’S INDEMNITY. To the maximum extent this agreement may be made effective according to law, and subject to Section 13.4, Tenant
agrees to indemnify and save harmless Landlord from and against all claims for personal injury or property damage arising from or claimed to have arisen from any 



 

 42 









	 	
accident, injury or damage whatsoever caused to any person, or to the property of any person, occurring in or about the Premises after the date that possession of the Premises is first delivered
to Tenant and until the end of the Lease Term and thereafter, provided that during any such period after the Lease Term Tenant or anyone acting by, through or under Tenant is in occupancy of the Premises or any portion thereof (except to the extent
the same is caused by the negligence or willful misconduct of Landlord or its agents, contractors or employees); or any accident, injury or damage occurring outside the Premises but within the Building or the Common Areas, or the Garage, to the
extent that such accident, injury or damage results from the negligence or willful misconduct on the part of Tenant or Tenant’s agents, employees, contractors or licensees; or any claims resulting from a breach of Tenant’s obligations
under Section 9.4 of the Lease. 

  

	    	This indemnity and hold harmless agreement shall include indemnity against all costs, expenses and liabilities incurred in or in connection with any such claim or
proceeding brought thereon, and the defense thereof. 

  

	13.2	LIABILITY INSURANCE. Tenant agrees to maintain in full force from the date upon which Tenant first enters the Premises for any reason, throughout the Lease Term
of this Lease, and thereafter, so long as Tenant is in occupancy of any part of the Premises, a policy of commercial general liability or comprehensive general liability insurance written on an occurrence basis with a broad form comprehensive
liability endorsement under which Landlord and Landlord’s managing agent (and such other persons as are in privity of estate with Landlord and Landlord’s managing agent as may be set out in notice from time to time) are named as additional
insured parties and Tenant is named as insureds, and under which the insurer agrees to indemnify and hold Landlord and Landlord’s managing agent, and those in privity of estate with Landlord and Landlord’s managing agent, harmless from and
against all cost, expense and/or liability arising out of or based upon any and all claims, accidents, injuries and damages mentioned in Section 13.1 of this Article XIII, in the broadest form of such coverage from time to time available in the
jurisdiction in which the Premises are located. Each such policy shall be non-cancelable and non-amendable with respect to Landlord and Landlord’s said designees without thirty (30) days’ prior notice to Landlord, and a duplicate
original or certificate thereof shall be delivered to Landlord. As of the Commencement Date hereof, the minimum limits of liability of such insurance shall be as specified in Section 1.2 and from time to time during the Lease Term for such
higher limits, if any, as are carried customarily in the Greater Boston area with respect to similar properties. All insurance required to be maintained by Tenant pursuant to this Lease shall be maintained with responsible companies qualified to do
business, and in good standing, in the Commonwealth of Massachusetts and which have a rating of at least “A-” and are within a financial size category of not less than “Class VIII” in the most current Best’s Key Rating Guide
or such similar rating as may be reasonably selected by Landlord if such Guide is no longer published. 

  

 43 









	13.3	TENANT’S PROPERTY INSURANCE. Tenant, at Tenant’s expense, shall maintain at all times during the Term of the Lease insurance against loss or damage
covered by the so-called “all risk” type insurance coverage with respect to Tenant’s fixtures, equipment, goods, wares and merchandise, tenant improvements (except the improvements made under Article IV of this Lease which shall be
covered under the casualty insurance for the Building) made by or paid for by Tenant, and other property of Tenant (collectively “Tenant’s Property”). Such insurance shall be in an amount at least equal to the full replacement cost of
Tenant’s Property, subject to commercially reasonable deductibles. 

  

	13.4	NON-SUBROGATION. Any insurance carried by either party with respect to the Premises, building or Lot or property therein or occurrences thereon shall, if it can
be so written without additional premium or with an additional premium which the other party agrees to pay, include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by
the insured prior to occurrence of injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby waives any rights of recovery against the other for injury or loss due to hazards (i) covered by such insurance
(provided, however, that such waiver from Landlord to Tenant shall not cover the deductible referenced in Section 13.6 hereof), and (ii) which would have been covered by insurance required to be carried by such party under this Lease but
not in fact so carried. Without limitation, this waiver of rights by Tenant shall apply to, and be for the benefit of, Landlord’s managing agent. 

  

	13.5	TENANT’S RISK. To the maximum extent that this agreement may be made effective according to law, Tenant agrees to use and occupy the Premises and to use
such other portions of the Building, the Common Areas or the Garage as Tenant is herein given the right to use at Tenant’s own risk; and Landlord shall not have any responsibility or liability for any loss of or damage to fixtures or other
personal property of Tenant, unless, subject to Section 13.4 hereof, such damage or loss is due to the negligence or willful misconduct of Landlord or its agents, employees or contractors, in which case Landlord shall bear loss or damage only
to “ordinary office property” (as hereinafter defined). For the purpose of this Section 13.5, “ordinary office property” shall mean merchandise, furniture, and other tangible personal property of the kind and quantity which
may customarily be expected to be found within comparable business offices in the City of Cambridge, and excluding any unusually valuable or exotic property, works of art, and the like. 


 

 44 









	13.6	LANDLORD’S INSURANCE. Landlord shall carry at all times during the Term of this Lease (and the specific coverages listed below shall be adjusted to reflect
current values from time to time) (i) commercial general liability insurance with respect to the Building in an amount not less than $5,000,000.00 combined single limit per occurrence, (ii) with respect to the Building, including all work
which Landlord or Tenant initially installs in the Premises pursuant to Article IV, insurance against loss or damage caused by any peril covered under fire, extended coverage and all risk insurance with coverage against vandalism, malicious mischief
and such other insurable hazards and contingencies as are from time to time normally insured against by owners of similar multi-tenant office buildings in Boston or Cambridge or which are required by Landlord’s mortgagee, in an amount equal to
the full replacement cost thereof above foundation walls. Further, Landlord may also maintain such insurance against loss of Annual Fixed Rent and Additional Rent for up to twelve months (or such longer period of time as Landlord’s mortgagee
may require) and such other risks and perils as Landlord deems proper, consistent with other similar office buildings in the Greater Boston area. Any and all such insurance (i) may be maintained under a blanket policy affecting other properties
of Landlord and/or its affiliated business organizations, (ii) may be written with deductibles as determined by Landlord and (iii) shall be subject to escalation reimbursement in accordance with Sections 7.4 and 7.5.


 ARTICLE XIV 

FIRE, CASUALTY AND TAKING 
  

	14.1	DAMAGE RESULTING FROM CASUALTY. 


(A) Landlord’s Termination Rights based upon Estimated Restoration Period. In case during the Lease Term the Building is
damaged by fire or other casualty (i) at any time by an occurrence which is not covered by the insurance Landlord is required to obtain under this Lease, or otherwise has obtained, and the cost to repair such damage exceeds five percent
(5%) of the then fair market value of the Building immediately before such casualty, or (ii) Landlord elects to demolish the Building and terminate the leases for substantially all of the space in the Building, or (iii) at any time
during the last eighteen (18) months of the term taking into account any extension option term which has not lapsed unexercised, if Landlord reasonably estimates that the time to repair such damage would exceed six (6) months or
(iv) such fire or casualty requires such substantial alteration or reconstruction of the Building that the damage cannot, in the ordinary course, reasonably be expected to be repaired within twelve (12) months from the date of such fire or
casualty as reasonably determined by Landlord and Landlord terminates the leases for substantially all of the space in the Building, then, in any such events, this Lease and the Term hereof may be terminated at the election of Landlord by a notice
in writing of its election so to terminate which shall be given 
  

 45 








 
by Landlord to Tenant within sixty (60) days following such fire or other casualty, the effective termination date of which shall be not less than thirty (30) days after the day on
which such termination notice is received by Tenant. Unless terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect following any such damage subject, however, to the following provisions. 

(B) Landlord’s Termination Right based upon Insufficient Insurance Proceeds. Notwithstanding anything to the contrary
contained in this Lease, if: (i) the Building or the Premises shall be substantially damaged by fire or casualty as the result of a risk not covered by the forms of casualty insurance required under this Lease to be maintained, or otherwise
maintained, by Landlord and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within thirty (30) days from the time that repair work would commence, or (ii) if the holder of any mortgage or
any ground lessor will not allow the net proceeds of insurance to be applied to the restoration of the Building, or (iii) if the net insurance proceeds shall be insufficient to complete such repairs and restoration, Landlord may, at its
election, terminate the Term of this Lease by notice to Tenant given within sixty (60) days after such loss. If Landlord shall give such notice, then this Lease shall terminate as of the date specified in such notice, which shall be not less
than thirty (30) days after the day on which such termination notice is received by Tenant, with the same force and effect as if such date were the date originally established as the expiration date hereof. 

(C) Tenant’s Termination Right Based upon Estimated Period of Restoration. If any portion of the Premises or any portion of
the Building shall be damaged or destroyed by fire or other casualty to the extent that the operation of Tenant’s business in the Premises in the normal course is materially adversely affected, then, within sixty (60) days of such fire or
other casualty, Landlord shall submit to Tenant a reasonable engineering estimate as to the estimated length of time (“Estimated Restoration Period”) to complete such repairs together with a statement of whether or not Landlord will
receive sufficient proceeds from insurance to repair such damage. If the time period set forth in such estimate shall exceed ten (10) months from the date of such casualty (which period shall be shortened to six (6) months during the last
eighteen (18) months of the term taking into account any extension option term which has not lapsed unexercised) or if Landlord advises Tenant in such notice that Landlord will not receive sufficient proceeds from insurance to repair such
damage and that Landlord does not intend to fund such insufficiency, Tenant may elect to terminate this Lease, by a notice sent within thirty (30) days after notice of such estimate is sent to Tenant, the effective termination date of which
shall be not less than forty-five (45) days after the day on which such termination notice is received by Landlord. If such estimate shall fall within the ten (10) month limit and if Landlord advises Tenant in such notice that Landlord
will receive sufficient proceeds from insurance to repair such damage, Tenant shall have no such right to terminate pursuant to this paragraph. 
  

 46 








 (D) Tenant’s Termination Right Based upon Actual Period of Restoration. In the
event that the Premises or the Building are damaged by fire or other casualty to the extent that the operation of Tenant’s business in the Premises in the normal course is materially adversely affected and the Lease is not terminated by either
Landlord pursuant to Sections 14.1(A) or 14.1(B) or by Tenant pursuant to Sections 14.1(C) or 14.1(E), and if Landlord shall fail to substantially complete said repairs or restoration on or before the date (“Restoration Deadline
Date”) which is the greater of: (1) the end of the Estimated Restoration Period and (2) ten (10) months after the date of such fire or other casualty (which ten (10) month period shall be automatically extended for up to an
additional two (2) months for such periods of time as Landlord is prevented from proceeding with or completing the same by reason of causes beyond Landlord’s reasonable control, and such further time as Landlord may be delayed by reason of
Tenant’s fault), Tenant may terminate this Lease by giving Landlord written notice as follows: 
  

	 	(i)	Said notice shall be given after the Restoration Deadline Date. 

  

	 	(ii)	Said notice shall set forth an effective date which is not earlier than thirty (30) days after Landlord receives said notice. 


 

	 	(iii)	If said repairs or restoration are substantially complete on or before the date thirty (30) days (which thirty-(30)-day period shall be extended by the length of
any delays caused by Tenant or Tenant’s contractors) after Landlord receives such notice, said notice shall have no further force and effect. 

  

	 	(iv)	If said repairs or restoration are not substantially complete on or before the date thirty (30) days (which thirty-(30)-day period shall be extended by the length
of any delays caused by Tenant or Tenant’s contractors) after Landlord receives such notice, the Lease shall terminate as of said effective date. 


(E) Tenant’s Termination Right Based upon Insufficient Insurance Proceeds. Landlord shall, within sixty (60) days of
such fire or other casualty, notify Tenant if the holder of any mortgage or any ground lessor will not allow the net proceeds of insurance to be applied to the restoration of the Building, or if the net insurance proceeds shall be insufficient to
complete such repairs and restoration, and if Landlord does not intend to fund such insufficiency. In such event, Tenant shall have the right to terminate the Lease, by written notice given to Landlord within thirty (30) days of Tenant’s
receipt of Landlord’s notice of insufficient proceeds, the effective termination date of which shall be not less than forty-five (45) days after the day on which such termination notice is received by Landlord. 

 

 47 








 (F) Landlord’s Restoration Obligation; Abatement of Rent. If the Building or any
part thereof, including the Premises, is damaged by fire or casualty and this Lease is not so terminated, or Landlord has no right to terminate this Lease, and in either such case the holder of any mortgage which includes the Building as a part of
the mortgaged premises or any ground lessor of any ground lease which includes the Building as part of the demised premises allows the net insurance proceeds to be applied to the restoration of the Building and/or or the Premises, Landlord, promptly
after such damage and the determination of the net amount of insurance proceeds available shall use due diligence to restore the Premises and the Building in the event of damage thereto into substantially the same condition which existed immediately
prior to such fire or casualty (excluding Tenant’s Property) and a just proportion of the Annual Fixed Rent, the Operating Cost Excess and Tax Excess according to the nature and extent of the injury to the Premises (or Tenant’s means of
access thereto) shall be abated from the date of casualty until the Premises (and Tenant’s means of access thereto) shall have been put by Landlord into such condition. 

 

	14.2	RIGHTS OF TERMINATION FOR TAKING. 


(A) If the Building, or such portion thereof as to render the balance (if reconstructed to the maximum extent practicable in the
circumstances) unsuitable for Tenant’s purposes, shall be taken by condemnation or right of eminent domain, Landlord or Tenant shall have the right to terminate this Lease by notice to the other of its desire to do so, provided that such notice
is given not later than thirty (30) days after Tenant has been deprived of possession. If either party shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the
date originally established as the expiration date hereof. 
 (B) Further, if so much of the Building shall be so taken that
continued operation of the Building would be uneconomic, Landlord shall have the right to terminate this Lease by giving notice to Tenant of Landlord’s desire to do so not later than thirty (30) days after Tenant has been deprived of
possession of the Premises (or such portion thereof as may be taken). If Landlord shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally
established as the expiration date hereof. 
 (C) Should any part of the Premises be so taken or condemned during the Lease Term
hereof, and should this Lease not be terminated in accordance with the foregoing provisions, and the holder of any mortgage which includes the Premises as part of the mortgaged premises or any ground lessor of any ground

  

 48 








 
lease which includes the Premises as part of the demised premises allows the net condemnation proceeds to be applied to the restoration of the Building, Landlord agrees that after the
determination of the net amount of condemnation proceeds available to Landlord, Landlord shall use due diligence to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the Premises prior
to such taking as shall be practicable (excluding Tenant’s Property). Notwithstanding the foregoing, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net condemnation proceeds made available
to it. 
 (D) Tenant’s Termination Right Based upon Actual Period of Restoration. In the event that the Premises or
the Building are damaged by condemnation or right of eminent domain to the extent that the operation of Tenant’s business in the Premises in the normal course is materially adversely affected and the Lease is not terminated by either Landlord
pursuant to Sections 14.2(A) or 14.2(B) or Tenant pursuant to Section 14.2(A), and if Landlord shall fail to substantially complete said repairs or restoration on or before the date (“Restoration Deadline Date”) which is ten
(10) months after Tenant (or Landlord) is deprived of possession (which ten (10) month period shall be automatically extended for up to an additional two (2) months for such periods of time as Landlord is prevented from proceeding
with or completing the same by reason of causes beyond Landlord’s reasonable control, and such further time as Landlord may be delayed by reason of Tenant’s fault), Tenant may terminate this Lease by giving Landlord written notice as
follows: 
  

	 	(i)	Said notice shall be given after the Restoration Deadline Date. 

  

	 	(ii)	Said notice shall set forth an effective date which is not earlier than thirty (30) days after Landlord receives said notice. 


 

	 	(iii)	If said repairs or restoration are substantially complete on or before the date thirty (30) days (which thirty-(30)-day period shall be extended by the length of
any delays caused by Tenant or Tenant’s contractors) after Landlord receives such notice, said notice shall have no further force and effect. 

  

	 	(iv)	If said repairs or restoration are not substantially complete on or before the date thirty (30) days (which thirty-(30)-day period shall be extended by the length
of any delays caused by Tenant or Tenant’s contractors) after Landlord receives such notice, the Lease shall terminate as of said effective date. 


 

 49 








 (E) Tenant’s Termination Right Based upon Insufficient Taking Proceeds. Landlord
shall, within sixty (60) days of such condemnation or taking, notify Tenant if the holder of any mortgage or any ground lessor will not allow the net taking proceeds to be applied to the restoration of the Building, or if the net taking
proceeds shall be insufficient to complete such repairs and restoration, and if Landlord does not intend to fund such insufficiency. In such event, Tenant shall have the right to terminate the Lease, by written notice given to Landlord within thirty
(30) days of Tenant’s receipt of Landlord’s notice of insufficient proceeds, the effective termination date of which shall be not less than forty-five (45) days after the day on which such termination notice is received by Landlord.

 (F) If the Premises shall be affected by any exercise of the power of eminent domain and neither Landlord nor Tenant shall
terminate this Lease as provided above, then the Annual Fixed Rent, the Operating Cost Excess and the Tax Excess shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant; and
in case of a taking which permanently reduces the Rentable Floor Area of the Premises, a just proportion of the Annual Fixed Rent, the Operating Cost Excess and the Tax Excess shall be abated for the remainder of the Lease Term. 

 

	14.3	AWARD. Except as otherwise provided in this Section 14.3, Landlord shall have and hereby reserves and excepts, and Tenant hereby grants and assigns to
Landlord, all rights to recover for damages to the Building and the Garage and the leasehold interest hereby created, and compensation accrued or hereafter to accrue by reason of such taking, damage or destruction, as aforesaid, and by way of
confirming the foregoing, Tenant hereby grants and assigns, and covenants with Landlord to grant and assign to Landlord, all rights to such damages or compensation. 


However, nothing contained herein shall be construed to prevent Tenant from prosecuting in any such proceedings a claim for its trade
fixtures so taken or relocation, moving and other dislocation expenses, provided that such action shall not affect the amount of compensation otherwise recoverable by Landlord from the taking authority. 

ARTICLE XV 

DEFAULT 
  

	15.1	TENANT’S DEFAULT. This Lease and the term of this Lease are subject to the limitation that Tenant shall be in default if, at any time during the Lease Term,
any one or more of the following events shall occur and not be cured prior to the expiration of the grace period (if any) herein provided (herein called an “Event of Default” a “default of Tenant” or similar reference), as
follows: 

  

	 	(a)	Tenant shall fail to pay any installment of the Annual Fixed Rent, or any Additional Rent or any other monetary amount due under this Lease on or before the date on
which the same becomes due and payable, and such failure continues for ten (10) days after notice from Landlord thereof; or 

  

 50 









	 	(b)	Landlord having rightfully given the notice specified in (a) above to Tenant twice in any twelve (12) month period, Tenant shall fail thereafter within such
twelve (12) month period to pay the Annual Fixed Rent or estimated monthly payments of Additional Rent due under this Lease on or before the date on which the same becomes due and payable; or 


 

	 	(c)	Tenant shall fail to maintain general liability insurance, or the employment of labor and contractors within the Premises which interfere with Landlord’s work, in
violation of Section 4.3 or Section 9.3), and such failure or interference continues for three (3) business days after notice from Landlord to Tenant thereof; or 


 

	 	(d)	Tenant shall fail to perform or observe any other requirement, term, covenant or condition of this Lease (not hereinabove in this Section 15.1 specifically
referred to) on the part of Tenant to be performed or observed and such failure shall continue for thirty (30) days after notice thereof from Landlord to Tenant, or if said default shall reasonably require longer than thirty (30) days to
cure, if Tenant shall fail to commence to cure said default within thirty (30) days after notice thereof and/or fail to continuously prosecute the curing of the same to completion with due diligence; or 


 

	 	(e)	The estate hereby created shall be taken on execution or by other process of law; or 


 

	 	(f)	Tenant shall make an assignment or trust mortgage arrangement, so-called, for the benefit of its creditors; or 


 

	 	(g)	Tenant shall judicially be declared bankrupt or insolvent according to law; or 


 

	 	(h)	a receiver, guardian, conservator, trustee in involuntary bankruptcy or other similar officer is appointed to take charge of all or any substantial part of
Tenant’s property by a court of competent jurisdiction and such appointment is not discharged within ninety (90) days thereafter; or 

  

	 	(i)	any petition shall be filed against Tenant in any court, whether or not pursuant to any statute of the United States or of any State, in any bankruptcy, reorganization,
composition, extension, arrangement or insolvency proceeding, and such proceedings shall not be fully and finally dismissed within sixty (60) days after the institution of the same; or 


 

 51 









	 	(j)	Tenant shall file any petition in any court, whether or not pursuant to any statute of the United States or any State, in any bankruptcy, reorganization, composition,
extension, arrangement or insolvency proceeding. 

  

	15.2	TERMINATION: RE-ENTRY. Upon the happening of any one or more of the aforementioned Events of Default (notwithstanding any license of a former breach of covenant
or waiver of the benefit hereof or consent in a former instance), Landlord or Landlord’s agents or servants may give to Tenant a notice (hereinafter called “notice of termination”) terminating this Lease on a date specified in such
notice of termination (which shall be not less than five (5) days after the date of the mailing of such notice of termination), and this Lease and the Lease Term, as well as any and all of the right, title and interest of the Tenant hereunder,
shall wholly cease and expire on the date set forth in such notice of termination (Tenant hereby waiving any rights of redemption) in the same manner and with the same force and effect as if such date were the date originally specified herein for
the expiration of the Lease Term, and Tenant shall then quit and surrender the Premises to Landlord. 

 In addition
or as an alternative to the giving of such notice of termination, Landlord or Landlord’s agents or servants may, by any suitable action or proceeding at law, immediately or at any time thereafter re-enter the Premises and remove therefrom
Tenant, its agents, employees, servants, licensees, and any subtenants and other persons, and all or any of its or their property therefrom, and repossess and enjoy the Premises, together with all additions, alterations and improvements thereto;
but, in any event under this Section 15.2, Tenant shall remain liable as hereinafter provided. 
 The words
“re-enter” and “re-entry” as used throughout this Article XV are not restricted to their technical legal meanings. 
  

	15.3	 CONTINUED LIABILITY: RE-LETTING. If this Lease is terminated or if Landlord shall re-enter the Premises as aforesaid, or in the event of the
termination of this Lease, or of re-entry, by or under any proceeding or action or any provision of law by reason of an Event of Default hereunder on the part of Tenant, Tenant covenants and agrees forthwith to pay and be liable for, on the days
originally fixed herein for the payment thereof, amounts equal to the several installments of Annual Fixed Rent, all Additional Rent and other charges reserved as they would, under the terms of this Lease, become due if this Lease had not been
terminated or if Landlord had not entered or re-entered, as aforesaid, and whether the Premises be relet or remain vacant, in whole or in part, or for a period less than the remainder of the Lease Term, or for the whole thereof, but, in the event
the Premises be relet by Landlord, Tenant shall be entitled to a credit in the net amount of rent and other charges received by Landlord in reletting, after 



 

 52 









	 	
deduction of all reasonable expenses incurred in reletting the Premises (including, without limitation, remodeling costs, brokerage fees and the like), and in collecting the rent in connection
therewith, in the following manner: 

 Amounts received by Landlord after reletting shall first be applied against
such Landlord’s expenses of recovering the Premises from Tenant and reletting, until the same are recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is
obligated to pay under the terms of this Lease (Tenant’s liability prior to any such reletting and such recovery not in any way to be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for
in this Lease); when and if such expenses have been completely recovered, the amounts received from reletting by Landlord as have not previously been applied shall be credited against Tenant’s obligations as of each day when a payment would
fall due under this Lease, and only the net amount thereof shall be payable by Tenant. Further, Tenant shall not be entitled to any credit of any kind for any period after the date when the term of this Lease is scheduled to expire according to its
terms. 
 Landlord agrees to use reasonable efforts to relet the Premises after Tenant vacates the Premises in the event that the
Lease is terminated based upon a default by Tenant hereunder. Marketing of Tenant’s Premises in a manner similar to the manner in which Landlord markets other premises within Landlord’s control in the Building shall be deemed to have
satisfied Landlord’s obligation to use “reasonable efforts.” In no event shall Landlord be required to (i) solicit or entertain negotiations with any other prospective tenants for the Premises until Landlord obtains full and
complete possession of the Premises including, without limitation, the final and unappealable legal right to re-let the Premises free of any claim of Tenant, (ii) give preference to reletting the Premises over leasing other vacant space in the
Building, or (iii) lease the Premises if, in Landlord’s bona fide business judgment, the proposed rent is less than the then current fair market rental value of the Premises. 

 

	15.4	 LIQUIDATED DAMAGES. Landlord may elect, as an alternative, to have Tenant pay liquidated damages, which election may be made by notice given to
Tenant at any time after the termination of this Lease under Section 15.2, above, and whether or not Landlord shall have collected any damages as hereinbefore provided in this Article XV, and in lieu of all other such damages beyond the date of
such notice. Upon such notice, Tenant shall promptly pay to Landlord, as liquidated damages, in addition to any damages collected or due from Tenant from any period prior to such notice and all expenses which Landlord may have incurred with respect
to the collection of such damages, such a sum as at the time of such notice represents the amount of the excess, if any, of (a) the discounted present value, at a discount rate of 6%, of the Annual Fixed Rent, Additional Rent and other charges
which would have been payable by Tenant under this Lease for 


  

 53 









	 	
the remainder of the Lease Term if the Lease terms had been fully complied with by Tenant, over and above (b) the discounted present value, at a discount rate of 6%, of the Annual Fixed
Rent, Additional Rent and other charges that would be received by Landlord if the Premises were re- leased at the time of such notice for the remainder of the Lease Term at the fair market value (including provisions regarding periodic increases in
Annual Fixed Rent if such are applicable) prevailing at the time of such notice as reasonably determined by Landlord. 


For the purposes of this Article, if Landlord elects to require Tenant to pay liquidated damages in accordance with this
Section 15.4, the total rent shall be computed by assuming the Tax Excess under Section 6.2 and the Operating Cost Excess under Section 7.5 to be the same as were payable for the twelve (12) calendar months (or if less than
twelve (12) calendar months have been elapsed since the date hereof, the partial year) immediately preceding such termination of re-entry. 

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 proceeds in which, the damages are to be proved, whether or not the amount be
greater, equal to, or less than the amount of the loss or damages referred to above. 
  

	15.5	WAIVER OF REDEMPTION. Tenant, for itself and any and all persons claiming through or under Tenant, including its creditors, upon the termination of this Lease
and of the term of this Lease in accordance with the terms hereof, or in the event of entry of judgment for the recovery of the possession of the Premises in any action or proceeding, or if Landlord shall enter the Premises by process of law or
otherwise, hereby waives any right of redemption provided or permitted by any statute, law or decision now or hereafter in force, and does hereby waive, surrender and give up all rights or privileges which it or they may or might have under and by
reason of any present or future law or decision, to redeem the Premises or for a continuation of this Lease for the term of this Lease hereby demised after having been dispossessed or ejected therefrom by process of law, or otherwise.


  

	15.6	LANDLORD’S DEFAULT. 


Landlord shall in no event be in default in the performance of any of Landlord’s obligations hereunder unless and until Landlord
shall have failed to perform such obligations within thirty (30) days, or such additional time as is reasonably required to correct any such default, after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform
any such obligation. 
  

 54 








 ARTICLE XVI 

MISCELLANEOUS PROVISIONS 
  

	16.1	WAIVER. Failure on the part of Landlord or Tenant to complain of any action or non-action on the part of the other, no matter how long the same may continue,
shall never be a waiver by Tenant or Landlord, respectively, of any of its rights hereunder. 

 Further, no waiver
at any time of any of the provisions hereof by Landlord or Tenant shall be construed as a waiver of any of the other provisions hereof, and a waiver at any time of any of the provisions hereof shall not be construed as a waiver at any subsequent
time of the same provisions. The consent or approval of Landlord or Tenant to or of any action by the other requiring such consent or approval shall not be construed to waive or render unnecessary Landlord’s or Tenant’s consent or approval
to or of any subsequent similar act by the other. 
 No payment by Tenant, or acceptance by Landlord, of a lesser amount than
shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account. The acceptance by Landlord of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such
lesser amount is payment in full, shall be given no effect, and Landlord may accept such check without prejudice to any other rights or remedies which Landlord may have against Tenant. Further, the acceptance by Landlord of Annual Fixed Rent,
Additional Rent or any other charges paid by Tenant under this Lease shall not be or be deemed to be a waiver by Landlord of any default by Tenant, whether or not Landlord knows of such default, except for such defaults as to which such payment
relates. 
  

	16.2	CUMULATIVE REMEDIES. Except as expressly provided in this Lease, the specific remedies to which Landlord may resort under the terms of this Lease are cumulative
and are not intended to be exclusive of any other remedies or means of redress which they may be lawfully entitled to seek in case of any breach or threatened breach of any provisions of this Lease. In addition to the other remedies provided in this
Lease, Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to seek specific performance of any such covenants, conditions
or provisions, provided, however, that the foregoing shall not be construed as a confession of judgment by Tenant. 

  

	16.3	 QUIET ENJOYMENT. This Lease is subject and subordinate to all matters of record. Landlord agrees that, upon Tenant’s paying the Annual
Fixed Rent, Additional Rent and other charges herein reserved, and performing and observing the covenants, conditions and agreements hereof upon the part of Tenant to be performed and observed, Tenant shall and may peaceably hold and enjoy the



  

 55 









	 	
Premises during the term of this Lease, without interruption or disturbance from Landlord or persons claiming through or under Landlord, subject, however, to the terms of this Lease. This
covenant shall be construed as running with the land to and against subsequent owners and successors in interest, and is not, nor shall it operate or be construed as, a personal covenant of Landlord, except to the extent of the Landlord’s
interest in the Premises, and this covenant and any and all other covenants of Landlord contained in this Lease shall be binding upon Landlord and upon such subsequent owners or successors in interest of Landlord’s interest under this Lease,
including ground or master lessees, to the extent of their respective interests, as and when they shall acquire same and then only for so long as they shall retain such interest, provided that (subject to the provisions of Section 16.24 hereof)
each party serving as “landlord” hereunder shall remain liable for all matters arising during its ownership of the Property. 

  

	16.4	SURRENDER. 

 (A) No act or
thing done by Landlord during the Lease Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid, unless in writing signed by Landlord. No employee of Landlord or of Landlord’s
agents shall have any power to accept the keys of the Premises as an acceptance of a surrender of the Premises prior to the termination of this Lease; provided, however, that the foregoing shall not apply to the delivery of keys to Landlord or its
agents in its (or their) capacity as managing agent or for purpose of emergency access. In any event, however, the delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of the Lease or a
surrender of the Premises. 
 (B) Upon the expiration or earlier termination of the Lease Term, Tenant shall surrender the
Premises to Landlord in the condition as required by Sections 8.1 and 9.5, first removing all goods and effects of Tenant and completing such other removals as may be permitted or required pursuant to Section 9.5. 

 

	16.5	BROKERAGE. 

 (A) Tenant
warrants and represents that Tenant has not dealt with any broker in connection with the consummation of this Lease other than the broker, person or firm designated in Section 1.2 hereof; and in the event any claim is made against the Landlord
relative to Tenant’s dealings with brokers other than the broker designated in Section 1.2 hereof, Tenant shall defend the claim against Landlord with counsel of Tenant’s selection, subject to Landlord’s reasonable approval, and
save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim. 
  

 56 








 (B) Landlord warrants and represents that Landlord has not dealt with any broker in
connection with the consummation of this Lease other than the broker, person or firm designated in Section 1.2 hereof; and in the event any claim is made against the Tenant relative to Landlord’s dealings with brokers other than the broker
designated in Section 1.2 hereof, Landlord shall defend the claim against Tenant with counsel of Tenant’s selection and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim.

 (C) Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the broker, person or firm
designated in Section 1.2 hereof. 
  

	16.6	INVALIDITY OF PARTICULAR PROVISIONS. If any term or provision of this Lease, or the application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and each term and
provision of this Lease shall be valid and be enforced to the fullest extent permitted by law. 

  

	16.7	PROVISIONS BINDING. ETC. The obligations of this Lease shall run with the land, and except as herein otherwise provided, the terms hereof shall be binding upon
and shall inure to the benefit of the successors and assigns, respectively, of Landlord and Tenant and, if Tenant shall be an individual, upon and to his heirs, executors, administrators, successors and assigns. Each term and each provision of this
Lease to be performed by Tenant shall be construed to be both a covenant and a condition. The reference contained to successors and assigns of Tenant is not intended to constitute a consent to assignment by Tenant, but has reference only to those
instances in which Landlord may have later given consent to a particular assignment as required by the provisions of Article XII hereof. 

  

	16.8	RECORDING. Each of Landlord and Tenant agree not to record the within Lease, but each party hereto agrees, on the request of the other, to execute a so-called
Notice of Lease or short form lease in form recordable and complying with applicable law and reasonably satisfactory to Landlord’s and Tenant’s attorneys. In no event shall such document set forth the rent or other charges payable by
Tenant under this Lease; and any such document shall expressly state that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease. 


 

 57 









	16.9	NOTICES AND TIME FOR ACTION. Whenever, by the terms of this Lease, notice shall or may be given either to Landlord or to Tenant, such notices shall be in writing
and shall be sent by hand, registered or certified mail, or overnight or other commercial courier, postage or delivery charges, as the case may be, prepaid as follows: 


If intended for Landlord, addressed to Landlord at the address set forth on the first page of this Lease (or to such other address or
addresses as may from time to time hereafter be designated by Landlord by like notice), with a copy to Goulston & Storrs, P.C., 400 Atlantic Avenue, Boston, MA 02110, Attn: Barry D. Green, Esq. 

If intended for Tenant, addressed to Tenant at the address set forth on the first page of this Lease, except that from and after the
Commencement Date the address of Tenant shall be the Premises (or to such other address or addresses as may from time to time hereafter be designated by Tenant by like notice), in either case with a copy to Hale and Dorr LLP, 60 State Street,
Boston, MA 02109, Attn: Paul Jakubowski, Esq. 
 Except as otherwise provided herein, all such notices shall be effective and
deemed received when received; provided, that (i) if receipt is refused, notice shall be effective and deemed received upon the first occasion that such receipt is refused or (ii) if the notice is unable to be delivered due to a change of
address of which no notice was given, notice shall be effective and deemed received upon the date such delivery was attempted. 

Where provision is made for the attention of an individual or department, the notice shall be effective only if the wrapper in which such
notice is sent is addressed to the attention of such individual or department. 
 Any notice given by an attorney on behalf of
Tenant or Landlord or by Landlord’s managing agent shall be considered as given by Tenant or Landlord, as the case may be, and shall be fully effective. 

Time is of the essence with respect to any and all notices and periods for giving of notice or taking any action thereto under this Lease.

  

	16.10	WHEN LEASE BECOMES BINDING. Employees or agents of Landlord have no authority to make or agree to make a lease or any other agreement or undertaking in
connection herewith. The submission of this document for examination and negotiation does not constitute an offer to lease, or a reservation of, or option for, the Premises, and this document shall become effective and binding only upon the
execution and delivery hereof by both Landlord and Tenant. All negotiations, considerations, representations and understandings between Landlord and Tenant are incorporated herein and may be modified or altered only by written agreement between
Landlord and Tenant, and no act or omission of any employee or agent of Landlord shall alter, change or modify any of the provisions hereof. 

  

 58 









	16.11	PARAGRAPH HEADINGS. The paragraph headings throughout this instrument are for convenience and reference only, and the words contained therein shall in no way be
held to explain, modify, amplify or aid in the interpretation, construction or meaning of the provisions of this Lease. 

  

	16.12	RIGHTS OF MORTGAGEE. This Lease shall be subject and subordinate to any future mortgage on the Lot or the Building, or both, or any part thereof, and to all
renewals, modifications, consolidations, replacements and extensions thereof and all substitutions therefor, provided that the holder of such mortgage shall agree, by a written instrument on such holder’s then-current form, with such
commercially reasonable changes as Tenant and such mortgagee agree upon, to recognize the right of Tenant to use and occupy the Premises upon the payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant of
Tenant’s obligations hereunder. Tenant shall pay fifty percent (50%) of any charges, including attorneys’ fees, required to be paid by such mortgagee as a condition of entering into such instrument, up to a maximum of $1,000.00. In
confirmation of such subordination and recognition, Tenant shall execute and deliver promptly such instruments of subordination as such mortgagee may reasonably request, In addition, Landlord agrees to use reasonable efforts to obtain a
subordination, non-disturbance and attornment agreement from its current mortgagee, and Tenant agrees (i) that the form attached hereto as Exhibit J is such mortgagee’s standard form, and any changes thereto must be agreed to by such
mortgagee; (ii) Tenant is not obligated to execute a subordination, non-disturbance and attornment agreement with such mortgagee if it chooses not to; and (iii) to pay fifty percent (50%) of any charges (including legal fees) required
by such mortgagee as a condition to entering into such agreement, up to a maximum of $1,000.00. In the event that any mortgagee or its respective successor in title shall succeed to the interest of Landlord, then this Lease shall nevertheless
continue in full force and effect and Tenant shall and does hereby agree to attorn to such mortgagee or successor and to recognize such mortgagee or successor as its landlord. If any holder of a mortgage which includes the Premises, executed and
recorded prior to the Date of this Lease, shall so elect, this Lease, and the rights of Tenant hereunder, shall be superior in right to the rights of such holder, with the same force and effect as if this Lease had been executed, delivered and
recorded, or a statutory Notice hereof recorded, prior to the execution, delivery and recording of any such mortgage. The election of any such holder shall become effective upon either notice from such holder to Tenant in the same fashion as notices
from Landlord to Tenant are to be given hereunder or by the recording in the appropriate registry or recorder’s office of an instrument in which such holder subordinates its rights under such mortgage to this Lease. 


 

 59 









	16.13	RIGHTS OF GROUND LESSOR. This Lease is subject and subordinate to all matters of record. If Landlord’s interest in property (whether land only or land and
buildings) which includes the Premises is acquired by another party and simultaneously leased back to Landlord herein, then the holder of the ground lessor’s interest in such lease shall enter into a recognition agreement with Tenant
simultaneously with the sale and leaseback, in form reasonably acceptable to Tenant, wherein the ground lessor will agree to recognize the right of Tenant to use and occupy the Premises upon the payment of Annual Fixed Rent, Additional Rent and
other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder, and wherein Tenant shall agree to attorn to such ground lessor as its Landlord and to perform and observe all of the tenant
obligations hereunder, in the event such ground lessor succeeds to the interest of Landlord hereunder under such ground lease. Tenant shall pay fifty percent (50%) of any charges, including attorneys’ fees, required to be paid by such
holder as a condition of entering into such instrument, up to a maximum of $1,000.00. 

  

	16.14	NOTICE TO MORTGAGEE AND GROUND LESSOR. After receiving notice from any person, firm or other entity that it holds a mortgage which includes the Premises as part
of the mortgaged premises, or that it is the ground lessor under a lease with Landlord as ground lessee, which includes the Premises as a part of the leased premises, no notice from Tenant to Landlord shall be effective unless and until a copy of
the same is given to such holder or ground lessor at the address as specified in said notice (as it may from time to time be changed), and the curing of any of Landlord’s defaults by such holder or ground lessor within a reasonable time after
such notice (including a reasonable time to obtain possession of the premises if the mortgagee or ground lessor elects to do so) shall be treated as performance by Landlord. For the purposes of this Section 16.14, the term “mortgage”
includes a mortgage on a leasehold interest of Landlord (but not one on Tenant’s leasehold interest). If any mortgage is listed on Exhibit H then the same shall constitute notice from the holder of such mortgage for the purposes of this
Section 16.14. 

  

	16.15	ASSIGNMENT OF RENTS. With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the rents payable hereunder, conditional in
nature or otherwise, which assignment is made to the holder of a mortgage or ground lease on property which includes the Premises, Tenant agrees: 

  

	 	(a)	That the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage, or the ground lessor, shall never be treated as an assumption by such
holder or ground lessor of any of the obligations of Landlord hereunder, unless such holder, or ground lessor, (i) shall foreclose its mortgage, accept a deed in lieu of foreclosure or terminate the ground lease, (ii) shall take possession
of the Premises, or (iii) shall, by notice sent to Tenant, specifically otherwise elect; and 

  

 60 









	 	(b)	That, except as aforesaid, such holder or ground lessor shall be treated as having assumed Landlord’s obligations hereunder only upon foreclosure of such
holder’s mortgage, acceptance of a deed in lieu of foreclosure or the taking of possession of the Premises, or, in the case of a ground lessor, the assumption of Landlord’s position hereunder by such ground lessor, or termination of the
ground lease. In no event shall the acquisition of title to the Building and the land on which the same is located by a purchaser which, simultaneously therewith, leases the entire Building or such land back to the seller thereof be treated as an
assumption, by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder. In
any such event, this Lease shall be subject and subordinate to the lease to such purchaser provided that such purchaser-lessor agrees to recognize the right of Tenant to use and occupy the Premises upon the payment of rent and all other charges
payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations under this Lease. For all purposes, such seller-lessee, and its successors in title, shall be the landlord hereunder unless and until Landlord’s
position shall have been assumed by such purchaser-lessor or the ground lease is terminated. The following provisions shall apply to Tenant and shall be included by Tenant in any sublease: except for the initial prepayment of rent provided in
Section 1.2, no Annual Fixed Rent or Additional Rent may be paid by Tenant more than thirty (30) days in advance except with lender’s prior written consent, and any such payment without such consent shall not be binding on lender.


  

	16.16	 STATUS REPORT AND FINANCIAL STATEMENTS. Recognizing that Landlord and Tenant may find it necessary to establish to third parties, such as
accountants, banks, potential or existing mortgagees, potential purchasers or the like, the then current status of performance hereunder, Landlord and Tenant, within ten (10) days after the request of the other party (the “Requesting
Party”) made from time to time, will furnish to the Requesting Party, or any existing or potential holder of any mortgage encumbering the Premises or the Building, or any potential purchaser of the Premises or the Building (each an
“Interested Party”) a statement of the status of any matter pertaining to this Lease, including, without limitation, acknowledgments that (or the extent to which) each party is in compliance with its obligations under the terms of this
Lease. Tenant agrees that its statement will be in the form attached hereto as Exhibit K, with such commercially reasonable changes as Tenant and the recipient of such statement shall agree upon. In addition, Tenant shall deliver to Landlord, or any
Interested Party designated by Landlord, financial statements of Tenant, and any guarantor of 


  

 61 









	 	
Tenant’s obligations under this Lease, as reasonably requested by Landlord (which request (i) shall be made only in connection with a proposed sale or refinancing of the Building or if
Tenant is in default of its obligations hereunder, and (ii) shall be made not more than once in any twelve (12) month period unless Tenant is in default of its obligations hereunder) including, but not limited to, financial statements for
the past three (3) years. Any such financial statements delivered by Tenant pursuant to this Section 16.16 shall be treated as confidential and may be disclosed only (i) as required by court order, (ii) to prospective purchasers
and lenders and to financial advisors, investment bankers, lawyers and accountants, (iii) as may be required by Legal Requirements, or (iv) in connection with litigation between the parties. Any such status statement or financial statement
delivered by Tenant pursuant to this Section 16.16 may be relied upon by any Interested Party. 

  

	16.17	SELF-HELP. If Tenant shall at any time fail to make any payment or perform any act which Tenant is obligated to make or perform under this Lease and (except in
the case of emergency) if the same continues unpaid or unperformed beyond applicable grace periods, then Landlord may, but shall not be obligated so to do, after ten (10) days’ notice to and demand upon Tenant, or without notice to or
demand upon Tenant in the case of any emergency, and without waiving, or releasing Tenant from, any obligations of Tenant in this Lease contained, make such payment or perform such act which Tenant is obligated to perform under this Lease in such
manner and to such extent as may be reasonably necessary, and, in exercising any such rights, pay any costs and expenses, employ counsel and incur and pay reasonable attorneys’ fees. All sums so paid by Landlord and all reasonable and necessary
costs and expenses of Landlord incidental thereto, together with interest thereon at the annual rate equal to the sum of (a) the Base Rate from time to time announced by Fleet National Bank, N.A. or its successor as its Base Rate and
(b) two percent (2%) (but in no event greater than the maximum rate permitted by applicable law), from the date of the making of such expenditures by Landlord, shall be deemed to be Additional Rent and, except as otherwise in this Lease
expressly provided, shall be payable to the Landlord on demand, and if not promptly paid shall be added to any rent then due or thereafter becoming due under this Lease, and Tenant covenants to pay any such sum or sums with interest as aforesaid,
and Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of the non-payment thereof by Tenant as in the case of default by Tenant in the payment of Annual Fixed Rent.


  

	16.18	 HOLDING OVER. Any holding over by Tenant after the expiration of the term of this Lease shall be treated as a tenancy at sufferance and shall be
on the terms and conditions as set forth in this Lease, as far as applicable except that Tenant shall pay as a use and occupancy charge an amount equal to the greater of (x) the Holdover Percentage, as hereinafter defined, of the Annual Fixed
Rent and 


  

 62 









	 	
Additional Rent calculated (on a daily basis) at the highest rate payable under the terms of this Lease, or (y) the fair market rental value of the Premises, in each case for the period
measured from the day on which Tenant’s hold-over commences and terminating on the day on which Tenant vacates the Premises. For purposes hereof, the “Holdover Percentage” shall be one hundred fifty percent (150%) for the first
thirty (30) days of such holding over, and two hundred percent (200%) from and after the thirty-first (31st) day of such holding over. 


In addition, if Tenant holds over for fifteen (15) days or more, Tenant shall save Landlord, its agents and employees harmless and
will exonerate, defend and indemnify Landlord, its agents and employees from and against any and all damages which Landlord may suffer on account of Tenant’s hold-over in the Premises after the expiration or prior termination of the term of
this Lease. Nothing in the foregoing nor any other term or provision of this Lease shall be deemed to permit Tenant to retain possession of the Premises or hold over in the Premises after the expiration or earlier termination of the Lease Term. All
property which remains in the Building or the Premises after the expiration or termination of this Lease shall be conclusively deemed to be abandoned and may either be retained by Landlord as its property or sold or otherwise disposed of in such
manner as Landlord may see fit. If any part thereof shall be sold, then Landlord may receive the proceeds of such sale and apply the same, at its option against the expenses of the sale, the cost of moving and storage, any arrears of rent or other
charges payable hereunder by Tenant to Landlord and any damages to which Landlord may be entitled under this Lease and at law and in equity. 
  

	16.19	ENTRY BY LANDLORD. Subject to Section 2.2, Landlord, and its duly authorized representatives, shall, upon reasonable prior notice (except in the case of
emergency), have the right to enter the Premises at all reasonable times (except at any time in the case of emergency) for the purposes of inspecting the condition of same and making such repairs, alterations, additions or improvements thereto as
Landlord is expressly permitted or required to make hereunder or as may be necessary if Tenant fails to do so as required hereunder (but the Landlord shall have no duty whatsoever to make any such inspections, repairs, alterations, additions or
improvements except as otherwise provided in Sections 4.1, 4.3, 7.1 and 7.2), and to show the Premises to prospective tenants during the twelve (12) months preceding expiration of the term of this Lease as it may have been extended and at any
reasonable time during the Lease Term to show the Premises to prospective purchasers and mortgagees. 

  

	16.20	 TENANT’S PAYMENTS. Each and every payment and expenditure, other than Annual Fixed Rent, shall be deemed to be Additional Rent hereunder,
whether or not the provisions requiring payment of such amounts specifically so state, and shall be payable, unless otherwise provided in this Lease, within thirty (30) days after written demand by Landlord, and in the case of the non-payment
of any such 


  

 63 









	 	
amount, Landlord shall have, in addition to all of its other rights and remedies, all the rights and remedies available to Landlord hereunder or by law in the case of non-payment of Annual Fixed
Rent. Unless expressly otherwise provided in this Lease, the performance and observance by Tenant of all the terms, covenants and conditions of this Lease to be performed and observed by Tenant shall be at Tenant’s sole cost and expense. If
Tenant has not objected to any statement of Additional Rent which is rendered by Landlord to Tenant within one hundred eighty (180) days after Landlord has rendered the same to Tenant, then the same shall be deemed to be a final account between
Landlord and Tenant not subject to any further dispute. In the event that Tenant shall seek Landlord’s consent or approval under this Lease, then Tenant shall reimburse Landlord, upon demand, as Additional Rent, for all reasonable costs and
expenses, including legal and architectural costs and expenses, incurred by Landlord in processing such request, whether or not such consent or approval shall be given. The foregoing sentence shall not apply, however, to Landlord’s approval of
the plans for the initial Landlord’s Work. 

  

	16.21	LATE PAYMENT. If Landlord shall not have received any payment or installment of Annual Fixed Rent or Additional Rent on or before the date (the “Due
Date”) on which the same first becomes payable under this Lease, the amount of such payment or installment shall bear interest from the Due Date through and including the date such payment or installment is received by Landlord, at a rate equal
to the lesser of (i) the rate announced by Fleet National Bank (or its successor) from time to time as its prime or base rate (or if such rate is no longer available, a comparable rate reasonably selected by Landlord), plus two percent (2%), or
(ii) the maximum applicable legal rate, if any. Such interest shall be deemed Additional Rent and shall be paid by Tenant to Landlord upon demand. 

  

	16.22	COUNTERPARTS. This Lease may be executed in several counterparts, each of which shall be deemed an original, and such counterparts shall constitute but one and
the same instrument. 

  

	16.23	ENTIRE AGREEMENT. This Lease constitutes the entire agreement between the parties hereto, Landlord’s managing agent and their respective affiliates with
respect to the subject matter hereof and thereof and supersedes all prior dealings between them with respect to such subject matter, and there are no verbal or collateral understandings, agreements, representations or warranties not expressly set
forth in this Lease. No subsequent alteration, amendment, change or addition to this Lease shall be binding upon Landlord or Tenant, unless reduced to writing and signed by the party or parties to be charged therewith. 


 

 64 









	16.24	LANDLORD LIABILITY. Tenant shall neither assert nor seek to enforce any claim for breach of this Lease against any of Landlord’s assets other than
Landlord’s interest in the Building, and Tenant agrees to look solely to such interest for the satisfaction of any liability of Landlord under this Lease, it being specifically agreed that neither Landlord, nor any successor holder of
Landlord’s interest hereunder, nor any beneficiary of any Trust of which any person from time to time holding Landlord’s interest is Trustee, nor any such Trustee, nor any member, manager, partner, director or stockholder nor
Landlord’s managing agent shall ever be personally liable for any such liability. This paragraph shall not limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or Landlord’s successors-in-interest,
or to take any other action which shall not involve the personal liability of Landlord, or of any successor holder of Landlord’s interest hereunder, or of any beneficiary of any trust of which any person from time to time holding
Landlord’s interest is Trustee, or of any such Trustee, or of any manager, member, partner, director or stockholder of Landlord or of Landlord’s managing agent, to respond in monetary damages from Landlord’s assets other than
Landlord’s interest in said Building, as aforesaid, but in no event shall Tenant have the right to terminate or cancel this Lease or to withhold rent or to set-off any claim or damages against rent as a result of any default by Landlord or
breach by Landlord of its covenants or any warranties or promises hereunder, except in the case of a wrongful eviction of Tenant from the demised premises (constructive or actual) by Landlord continuing after notice to Landlord thereof and a
reasonable opportunity for Landlord to cure the same. In no event shall Landlord or, except for liability pursuant to Section 16.18 hereof, Tenant ever be liable for any indirect or consequential damages or loss of profits or the like. In the
event that Landlord shall be determined to have wrongfully withheld any consent or approval under this Lease, the sole recourse and remedy of the Tenant in respect thereof shall be to specifically enforce Landlord’s obligation to grant such
consent or approval, and in no event shall the Landlord be responsible for any damages of whatever nature in respect of its failure to give such consent or approval nor shall the same otherwise affect the obligations of the Tenant under this Lease
or act as any termination of this Lease. 

  

	16.25	NO PARTNERSHIP. The relationship of the parties hereto is that of landlord and tenant and no partnership, joint venture or participation is hereby created.


  

	16.26	 SECURITY DEPOSIT. Concurrently with the execution of this Lease, Tenant shall pay to Landlord a security deposit in the amount of Eighteen
Thousand Two Hundred and 00/100 Dollars ($18,200.00) and Landlord shall hold the same, throughout the Term of this Lease (including the Extended Term, if applicable), unless sooner returned to Tenant as provided in this Section 16.26, as
security for the performance by Tenant of all obligations on the part of Tenant to be performed under this Lease. At Tenant’s option (which option may be exercised at any time during the Term of this Lease, but no more frequently than once in
any twelve (12) month period), such deposit may be in the form of an irrevocable, unconditional, negotiable letter of credit (the “Letter of Credit”). The Letter of



  

 65 









	 	
Credit shall (i) be issued by and drawn on a bank reasonably approved by Landlord and at a minimum having a corporate credit rating from Standard and Poor’s Professional Rating Service
of BBB- or a comparable minimum rating from Moody’s Professional Rating Service, (ii) be in the form attached hereto as Exhibit F, (iii) permit one or more draws thereunder to be made accompanied only by certification by Landlord that
pursuant to the terms of this Lease, Landlord is entitled to apply such Letter of Credit and the proceeds thereof to an Event of Default of Tenant under this Lease, and (iv) permit transfers of such letter of credit at any time without charge
to the beneficiary thereof. Any such Letter of Credit shall be for a term of two (2) years (or for one (1) year if the issuer thereof regularly and customarily only issues letters of credit for a maximum term of one (1) year) and
shall in either case provide for automatic renewals through the date which is ninety (90) days subsequent to the scheduled expiration of this Lease (as the same may be extended) or if the issuer will not grant automatic renewals, the Letter of
Credit shall be renewed or replaced by Tenant each year and each such renewal or replacement shall be delivered to and received by Landlord not later than thirty (30) days before the expiration of the then current Letter of Credit (herein
called a “Renewal Presentation Date”), the last such renewal or replacement to extend through the date which is ninety (90) days subsequent to the scheduled expiration of this Lease (as the same may be extended). In the event of a
failure to so deliver any such renewal Letter of Credit on or before the applicable Renewal Presentation Date, Landlord shall be entitled to present the then existing Letter of Credit for payment and to receive the proceeds thereof, which proceeds
shall be held as Tenant’s security deposit, subject to the terms of this Section 16.26. Upon the occurrence of any Event of Default, Landlord shall have the right from time to time without prejudice to any other remedy Landlord may have on
account thereof, to draw on all or any portion of such deposit held as a Letter of Credit and to apply the proceeds of such Letter of Credit or any cash held as such deposit, or any part thereof, to Landlord’s damages arising from such Event of
Default on the part of Tenant under the terms of this Lease. If Landlord so applies all or any portion of such deposit, Tenant shall within seven (7) days after notice from Landlord deposit cash or an additional Letter of Credit meeting all of
the requirements of this Section 16.26 with Landlord in an amount sufficient to restore such deposit to the full amount stated in this Section 16.26. While Landlord holds any cash deposit Landlord shall have no obligation to pay interest
on the same and shall have the right to commingle the same with Landlord’s other funds. Neither the holder of a mortgage nor the Landlord in a ground lease on property which includes the Premises shall ever be responsible to Tenant for the
return or application of any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall have been received in hand by such holder or ground Landlord. 


 

 66 








 If Tenant originally provides a cash security deposit hereunder, and then provides Landlord
with a letter of credit meeting all the requirements of this Section 16.26 in lieu thereof, Landlord shall return such cash security deposit to Tenant promptly upon Landlord’s receipt of said letter of credit. Tenant not then being in
default and having performed all of its obligations under this Lease, including the payment of all Annual Fixed Rent, Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of
this Section 16.26, to Tenant on the expiration or earlier termination of the term of this Lease (as the same may have been extended) and surrender possession of the Premises by Tenant to Landlord in the condition required in the Lease at such
time. Further, if Tenant has been in default or has failed to perform all of its obligations under this Lease, Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of this
Section 16.26, to Tenant upon the later to occur of (i) the curing of any such default and the full and final performance of all of Tenant’s obligations under this Lease, and (ii) the expiration or earlier termination of the term
of this Lease (as the same may have been extended) and surrender possession of the Premises by Tenant to Landlord in the condition required in the Lease at such time. 
  

	16.27	GOVERNING LAW. This Lease shall be governed exclusively by the provisions hereof and by the law of The Commonwealth of Massachusetts, as the same may from time
to time exist. 

  

	16.28	WAIVER OF TRIAL BY JURY. To induce Landlord to enter into this Lease, the Tenant hereby waives any right to trial by jury in any action, proceeding or
counterclaim brought by either Landlord or Tenant on any matters whatsoever arising out of or any way connected with this Lease, the relationship of the Landlord and the Tenant, the Tenant’s use or occupancy of the premises and/or any claim of
injury or damage, including but not limited to, any summary process eviction action. 

  

	16.29	INTENTIONALLY OMITTED. 

  

	16.30	SIGNAGE. Landlord shall provide building standard signage in the standard graphics for the Building listing Tenant and any permitted subtenant or assignee of
Tenant on the directory(ies) for the Building which serve the elevator bank serving the Premises. The initial listing of Tenant’s name shall be at Landlord’s expense. Any changes or additions to such directory(ies) shall be at
Tenant’s cost and expense. Tenant shall have the right, with Landlord’s prior written consent (which shall not be unreasonably withheld, delayed or conditioned), to install two signs identifying Tenant, one in the elevator lobby on the
floor of the Building containing the Premises and the other at the entrance to the Premises. Except as otherwise approved by Landlord, both such signs shall be in Building standard graphics. Such signs shall initially be provided by Landlord as part
of Landlord’s Work, but any changes or additions to such sign(s) shall be at Tenant’s sole cost and expense. 

  

 67 









	16.31	ARBITRATION. Any disputes relating to (i) provisions or obligations in this Lease as to which a specific provision for a reference to arbitration is made
herein (i.e. disputes under Articles VII), or (ii) the withholding of consent or approval where a “reasonableness” standard is specifically required by this Lease, shall be submitted to arbitration in accordance with the provisions of
applicable state law, as from time to time amended. Arbitration proceedings, including the selection of an arbitrator, shall be conducted pursuant to the rules, regulations and procedures from time to time in effect as promulgated by the American
Arbitration Association. Prior written notice of application by either party for arbitration shall be given to the other at least ten (10) days before submission of the application to the said Association’s office in Boston, Massachusetts.
The arbitrator shall hear the parties and their evidence. The decision of the arbitrator shall be binding and conclusive, and judgment upon the award or decision of the arbitrator may be entered in the appropriate court of law; and the parties
consent to the jurisdiction of such court and further agree that any process or notice of motion or other application to the Court or a Judge thereof may be served outside the Commonwealth of Massachusetts by registered mail or by personal service,
provided a reasonable time for appearance is allowed. The costs and expenses of each arbitration hereunder and their apportionment between the parties shall be determined by the arbitrator in his award or decision. No arbitrable dispute shall be
deemed to have arisen under this Lease prior to the expiration of the period of twenty (20) days after the date of the giving of written notice by the party asserting the existence of the dispute together with a description thereof sufficient
for an understanding thereof. 

  

	16.32	RULES AND REGULATIONS. Tenant will faithfully observe and comply with the rules and regulations attached hereto as Exhibit I and with such additional or modified
reasonable rules and regulations as Landlord hereafter at any time or from time to time may make and for which Landlord provides at least five (5) business days’ prior notice in writing to Tenant (referred to collectively herein as
“Rules and Regulations”), which in the reasonable judgment of Landlord shall be necessary for the reputation, safety, care or appearance of the Building, or the preservation of good order therein, or the operation or maintenance of the
Building, or the equipment thereof, or the comfort of tenants or others in the Building, provided, however, that in the case of any conflict between the provisions of this Lease and any such Rules and Regulations, the provisions of this Lease shall
control, and provided further that nothing contained in this Lease shall be construed to impose upon Landlord any duty or obligation to enforce the Rules and Regulations or the terms, covenants or conditions in any other lease as against any other
tenant and Landlord shall not be liable to Tenant for violation of the same by any other tenant, its servants, employees, agents, contractors, visitors, invitees or licensees. All Rules and Regulations shall be of general applicability to, and
non-discriminatorily applied against, all comparable tenants in the Building.

DAVENPORT BUILDING 

LANDLORD SERVICES 
  

	I.	CLEANING: 

 Cleaning and
janitorial services in the office areas and common areas of the Building on Business Days at a level comparable to services provided in similar office buildings in Cambridge, Massachusetts. 

 

	II.	HVAC: 

  

	 	A.	Landlord shall furnish to Tenant heated and chilled air as appropriate to the season, at such temperatures and in such amounts as are comparable to that provided by
landlords of similar office buildings of a similar age in Cambridge, Massachusetts. In the event Tenant introduces into the Premises personnel or equipment which overloads the system’s ability to adequately perform its proper functions,
Landlord shall so notify Tenant in writing and supplementary system(s) may be required and installed by Landlord at Tenant’s expense, if within fifteen (15) days Tenant has not modified its use so as not to cause such overload.


 Operating criteria of the basic system are in accordance with the Massachusetts Energy Code and shall not be
less than the following: 
  

	 	i)	Cooling season indoor conditions of not in excess of 78 degrees Fahrenheit when outdoor conditions are 91 degrees Fahrenheit drybulb and 73 degrees Fahrenheit wetbulb.


  

	 	ii)	Heating season minimum room temperature of 72 degrees Fahrenheit when outdoor conditions are 6 degrees Fahrenheit drybulb. 


 

	 	B.	Landlord shall provide heating, ventilating and air conditioning as normal seasonal charges may require during Normal Building Operating Hours (8:00 a.m. to 6:00 p.m.,
Monday through Friday, and 8:00 a.m. to 1:00 p.m. on Saturdays, legal holidays in all cases excepted). Temperatures within the Building during Normal Building Operating Hours shall be commensurate with temperatures generally maintained in other
Class A office buildings in the Boston/Cambridge market. 

  

 C-1 








 If Tenant shall require air conditioning (during the air conditioning season) or heating or
ventilating during any season outside Normal Building Operating Hours, Landlord shall use Landlord’s best efforts to furnish such services for the area or areas specified by written request of Tenant delivered to the Building Superintendent or
the Landlord before 3:00 p.m. of the business day preceding the extra usage. For such services, Tenant shall pay Landlord, as additional rent, upon receipt of billing, a sum equal to the cost incurred by Landlord.

typical office space. 

  

	 	B.	 Landlord, at its option, may require separate metering and direct billing to Tenant for the electric power required for any special equipment (such as
computers and reproduction equipment) that requires either 3-phase electric power or any voltage other than 110 volts (220 volts for Tenant’s kitchen), or for other equipment whose electrical energy consumption exceeds normal office usage
(collectively, “Special Equipment”). Tenant shall not install any Special Equipment in the Premises without first obtaining Landlord’s written approval (which approval shall not be unreasonably withheld, delayed or conditioned unless
the installation of such Special Equipment affects the Building’s structure or any of the Building’s mechanical, electrical, plumbing or HVAC equipment, in which case such approval may be granted or withheld in Landlord’s sole
discretion). If Tenant’s requirements for or consumption of electricity exceed the electricity to be provided by Landlord in this Section III, Landlord shall, at Tenant’s expense, use reasonable efforts to supply such service through the
then-existing feeders and risers serving the Building and the Premises, and Tenant shall pay to Landlord the cost of such service within ten (10) days after Landlord has delivered to Tenant an invoice therefor. The use of electricity in the
Premises shall not exceed the capacity of existing feeders and risers to or wiring in the Premises. Any risers or wiring required to meet Tenant’s excess electrical requirements shall, upon Tenant’s written request, be installed by
Landlord, at Tenant’s cost, if, in Landlord’s judgment, the same are necessary and shall not cause permanent damage to the Building or the Premises, cause or create a dangerous or hazardous condition, entail excessive or unreasonable
alterations, repairs or expenses, or interfere with or disturb other tenants of the Building. If Tenant uses machines or 



 

 C-2 









	 	
equipment in the Premises which affect the temperature otherwise maintained by the HVAC system or otherwise overload any utility, Landlord may install supplemental HVAC unit(s) or other
supplemental equipment in the Premises, and the cost thereof, including the cost of installation, operation, use and maintenance, shall be paid by Tenant to Landlord within ten (10) days after Landlord has delivered to Tenant an invoice
therefor.

fixtures upon written request of Tenant at Tenant’s expense.

 EXHIBIT G 

DETERMINATION OF FAIR MARKET RENTAL VALUE 

Where in the Lease to which this Exhibit is attached provision is made for a Determination of Fair Market Rental Value, the following
procedures and requirements shall apply: 
  

	1.	Tenant’s Request. Tenant shall send a notice to Landlord requesting a Determination of the Fair Market Rental Value, which notice to be effective must
(i) make explicit reference to the Lease and to the specific section of the Lease pursuant to which said request is being made, (ii) include the name of an appraiser selected by Tenant to act for Tenant, which appraiser shall be MAI
certified and which appraiser shall have at least ten (10) years’ experience dealing in properties of a nature and type generally similar to the Building located in the City of Cambridge, (iii) state Tenant’s estimate of fair
market rental value (“Tenant’s Quote”), and (iv) explicitly state that Landlord is required to notify Tenant within thirty (30) days of an additional appraiser selected by Landlord. 


 

	2.	Landlord’s Response. Within twenty (20) days after Landlord’s receipt of Tenant’s notice requesting the Determination and stating the name of
the appraiser selected by Tenant, Landlord and Tenant shall attempt to agree on a single appraiser having at least the certification and experience referred to above to make a determination of the annual fair market rental value of the Premises. If
the parties are unable to so agree on a single appraiser, then within ten (10) days after the expiration of such twenty (20) day period, Landlord shall give written notice to Tenant of Landlord’s selection of an appraiser having at
least the certification and experience referred to above, and within ten (10) days thereafter the two (2) appraisers so selected shall select a third such appraiser also having at least the certification and experience referred to above.
Such single appraiser or third appraiser, as the case may be, is hereinafter referred to as the “Deciding Appraiser.” 

  

	3.	 Rental Value Determination. Within thirty (30) days after the selection of the Deciding Appraiser, the Deciding Appraiser shall make a
determination of the annual fair market rental value of the Premises for the Extended Term. Such annual fair market rental value determination (x) may include provision for annual increases in rent during said Extended Term if so determined,
(y) shall take into account the as-is condition of the Premises and (z) shall take account of, and be expressed in relation to, the provisions for Operating Expenses and Taxes for the Building and Tenant Electricity as contained in the
Lease. The Deciding Appraiser shall advise Landlord and Tenant in writing by the expiration of said 



 

 G-1 









	 	
thirty (30) day period of his or her determination of such annual fair market rental value. The determination of the Deciding Appraiser shall be deemed to be the determination of annual fair
market rental value and shall be referred to as the Fair Market Rental Value, except that if the Deciding Appraiser’s determination is either higher or lower than both of Landlord’s Rent Quotation and Tenant’s Quote, then the one of
Landlord’s Rent Quotation or Tenant’s Quote which is closest to the determination of the Deciding Appraiser shall be deemed to be the determination of annual fair market rental value and shall be referred to as the Fair Market Rental
Value. 

  

	4.	Costs. Each party shall pay the costs and expenses, if any, of the appraiser selected by it and each shall pay one half (1/2) of the costs and expenses of
the Deciding Appraiser. 

  

	5.	Failure to Select Appraiser or Failure of Appraiser to Serve. If Tenant shall have requested a Determination and Landlord shall not have designated an appraiser
within the time period provided therefor above and such failure shall continue for more than ten (10) days after notice thereof, then Tenant’s appraiser shall alone make the determination of the Fair Market Rental Value in writing to
Landlord and Tenant within thirty (30) days after the expiration of Landlord’s right to designate an appraiser hereunder. If Tenant and Landlord have both designated appraisers but the two appraisers so designated do not, within a period
of fifteen (15) days after the appointment of the second appraiser, agree upon and designate the third appraiser willing so to act, the Tenant, the Landlord or either appraiser previously designated may request the Greater Boston Real Estate
Board, Inc. to designate the third appraiser willing so to act and an appraiser so appointed shall, for all purposes, have the same standing and powers as though he had been seasonably appointed by the appraisers first appointed. In case of the
inability or refusal to serve of any person designated as an appraiser, or in case any appraiser for any reason ceases to be such, an appraiser to fill such vacancy shall be appointed by the Tenant, the Landlord, the appraisers first appointed or
the said Greater Boston Real Estate Board, Inc., as the case may be, whichever made the original appointment, or if the person who made the original appointment fails to fill such vacancy, upon application of any appraiser who continues to act or by
the Landlord or Tenant such vacancy may be filled by the said Greater Boston Real Estate Board, Inc., and any appraiser so appointed to fill such vacancy shall have the same standing and powers as though originally appointed.

FORM OF SUBORDINATION, NONDISTURBANCE AND 

ATTORNMENT AGREEMENT 

SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT 

THIS AGREEMENT, dated the          day of
            , 2004, executed by and between MBO NORTH AMERICA FINANCE B.V. (hereinafter called “Lender”), and
                            , a
                     corporation (hereinafter called “Tenant”); 

WITNESSETH: 

WHEREAS, Davenport Cambridge Limited Partnership or its predecessor (hereinafter called “Borrower”) and Tenant have entered
into a certain Lease dated                     , 20     (the “Lease”), covering certain premises more
fully described in said Lease (the “Premises”) located at the Davenport Building, having an address of 25 First Street and 20-28 Otis Street, Cambridge, Massachusetts, more fully described on Exhibit “A” attached hereto and made
a part hereof (the “Property”); and 
 WHEREAS, by Mortgage filed with the Middlesex South Registry of Deeds at Book
         Page          (hereinafter called the “Mortgage”), Borrower has granted a first lien interest in the Property and the Premises to
Lender; and 
 WHEREAS, Tenant desires to be assured of continued occupancy of the Premises under the terms of the Lease;

 NOW, THEREFORE, in consideration of the sum of One Dollar ($1.00) by each party in hand paid to the other, the receipt of
which is hereby acknowledged, and in consideration of the mutual promises, covenants and agreements herein contained, the parties hereto, intending to be legally bound hereby, promise, covenant and agree as follows: 

1. The Lease and all estates, options (including purchase options, if any), liens and charges therein contained or created thereunder is
and shall be subject and subordinate to the lien and effect of the Mortgage insofar as it affects the real and personal property of which the Premises forms a part, and to all renewals, modifications, consolidations, replacements and extensions
thereof, to the full extent of the principal and other sums secured thereby and interest thereon, with the same force and effect as if the Mortgage had been executed, delivered, and duly recorded among the above-mentioned public records, prior to
the execution and delivery of this Lease. 
  

 J 1 








 2. In the event Lender takes possession of the Premises as mortgagee-in-possession or
forecloses the Mortgage (including, whenever reference is made to foreclosure in this Agreement, by exercise of Lender’s statutory power of sale), or takes a deed in lieu of foreclosure, Lender agrees not to affect or disturb Tenant’s
right to possession of the Premises in the exercise of Lender’s rights so long as Tenant is not in default beyond applicable notice and cure periods under any of the terms, covenants or conditions of the Lease. 

3. In the event that Lender succeeds to the interest of Borrower under the Lease and/or title to the Premises, Lender and Tenant hereby
agree to be bound to one another under all of the terms, covenants and conditions of the Lease. Accordingly, from and after such event, Lender and Tenant shall have the same remedies against one another for the breach of an agreement contained in
the Lease as Tenant and Borrower had before Lender succeeded to the interest of Borrower; provided, however, that Lender shall not be: 
  

	 	a.	liable for any act or omission of any prior landlord (including the Borrower); or 


 

	 	b.	subject to any offsets or defenses which Tenant might have against any prior landlord (including the Borrower); or 


 

	 	c.	bound by any rent or additional rent which Tenant might have paid for more than the current month to any prior landlord (including the Borrower); or


  

	 	d.	bound by any amendment or modification of the Lease made without Lender’s written consent unless the Premises consists of 25,000 square feet or less (in which
event Lender’s consent shall not be required); 

  

	 	e.	liable for the repayment of security deposits not actually received by the Lender; or 


 

	 	f.	liable for any obligation of prior landlord to restore the Property, including the Premises, except to the extent of insurance proceeds or condemnation awards actually
received by Lender after the deduction of all reasonable costs and expenses incurred in obtaining such proceeds or awards. 


4. In the event that any person or entity different from Lender acquires title to or the right to possession of the Premises upon the
foreclosure of the Mortgage, or upon the sale of the Premises by Lender or its successors or assigns after foreclosure or acquisition of title in lieu thereof or otherwise, Tenant agrees not to seek to terminate the Lease by reason thereof, but
shall remain bound unto the new owner so long as the new owner agrees to be bound to Tenant under all terms, covenants and conditions of the Lease, provided that the provisions of paragraph 3 hereof shall be applicable to, and shall fully benefit,
the person or entity so acquiring title. 
  

 J 2 








 5. In the event Lender takes possession of the Premises as mortgagee-in-possession or
forecloses the Mortgage, or takes a deed in lieu of foreclosure, Tenant agrees to pay all rental due under the Lease directly to Lender, Schenkkade 65, P.O. Box 90463, 2509 LL The Hague, The Netherlands, or such other address as Lender may designate
in writing to Tenant in the manner and at the address specified in the Lease. 
 6. Tenant hereby warrants and represents,
covenants and agrees with Lender: 
  

	 	a.	not to alter or modify the Lease in any respect without the prior written consent of Lender unless the Premises consists of 25,000 square feet or less (in which event
Lender’s consent shall not be required); 

  

	 	b.	to deliver to Lender a duplicate of each notice of default delivered to Borrower at the same time as such notice is given to Borrower; 


 

	 	c.	that Tenant is now the sole owner of the leasehold estate created by the Lease and shall not hereafter assign the Lease except as permitted by the terms thereof unless
Lender’s consent thereto is not required by the Mortgage or the other loan documents; 

  

	 	d.	not seek to terminate the Lease by reason of any default of Borrower without prior written notice thereof to Lender and the lapse thereafter of such time as provided
for herein. From the date hereof until the Mortgage is released, Lender shall have the right (but not the obligation) to cure any default of Borrower under the Lease (the cure period to include such time as may be required for Lender to cure such
default, including taking possession of the Premises, by foreclosure, through deed in lieu of foreclosure or otherwise). If Lender elects to cure said default and prosecutes such cure to completion as herein provided, Tenant will not exercise any
right or remedy to terminate the Lease upon a default by Borrower; 

  

	 	e.	not to pre-pay rent or other sums due under the Lease in advance for more than the current month; 


 

	 	f.	to promptly certify in writing to Lender, in connection with any proposed assignment of the Mortgage, certain matters relating to the Lease as may reasonably be
requested by Lender or such assignee of the Mortgage, including whether or not any default on the part of Borrower then exists under the Lease to the best knowledge of Tenant and whether to the best knowledge of Tenant, circumstances exist which,
with the giving of notice or the passage of time or both, would result in a default under the Lease. 

  

 J 3 









	 	g.	from the date hereof until the Mortgage is released, Tenant agrees to recognize the assignment of rents made by Borrower to Lender and, upon Tenant’s receipt of a
notice from Lender that Borrower is in default under the Mortgage beyond applicable notice and cure periods, Tenant will thereafter pay to Lender, as assignee, all rents due under the Lease until Lender gives Tenant notice that Borrower is no longer
in such default and instructs the Tenant that the rents shall thereafter be payable to Borrower. 

 7. This
Agreement, together with the Lease, represents the complete agreement between the parties and supersedes all earlier agreements, drafts, understandings or arrangements between the parties as to the Property and shall be binding upon the parties
hereto and their respective heirs, administrators, executors, successors and assigns. 
 8. This Agreement may be amended,
discharged or terminated, or any of its provisions may be waived, only by a written instrument executed by the party to be charged. 

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the day and year first above written.

NOW THEREFORE, the parties hereby agree that the above-referenced Lease is hereby amended as follows: 

 

	 	1.	DEMISE OF THE FOURTH AMENDMENT TEMPORARY PREMISES 


Landlord hereby demises and leases to Tenant, and Tenant hereby hires and takes from Landlord, the Fourth Amendment Temporary Premises for
a term commencing as of the date hereof (the “Fourth Amendment Temporary Premises Commencement Date”), and terminating as of the day prior to the Fourth Amendment Additional Premises Commencement Date (the “Fourth Amendment Temporary

	 	2.	DEMISE OF THE FOURTH AMENDMENT ADDITIONAL PREMISES. 


Landlord hereby demises and leases to Tenant, and Tenant hereby hires and takes from Landlord, the Fourth Amendment Additional Premises
for a term commencing on the date (the 
  

 3

terms and provisions of the Lease, as amended herein. 
  

	 	3.	THIRD AMENDMENT ADDITIONAL PREMISES.

	 	4.	CONDITION OF FOURTH AMENDMENT TEMPORARY PREMISES AND THE FOURTH AMENDMENT ADDITIONAL PREMISES 


The Fourth Amendment Temporary Premises and Fourth Amendment Additional Premises shall be demised to Tenant in “as-is”
condition, without any covenants or warranties by Landlord, and without any duty to improve the same. 
  

	 	5.	TENANT IMPROVEMENT ALLOWANCE 


As an inducement to Tenant’s entering into this Amendment, Landlord shall provide to Tenant an allowance equal to up to Thirty and
00/100 Dollars ($30.00) per square foot of Rentable Floor Area of the Fourth Amendment Additional Premises and up to Ten and 00/100 Dollars ($10.00) per square foot of Rentable Floor Area of the Core Premises (i.e., in aggregate up to Four Hundred
Sixty Nine Thousand, Eight Hundred and Forty and 00/100 Dollars ($469,840.00)) to be used by Tenant to pay for the cost of the performance of Tenant’s improvement work in the Fourth Amendment Additional Premises and the Core Premises

relating to each requisition in order to verify the amount thereof. Tenant shall submit requisition(s) no more often than monthly.

Landlord’s Contribution be applied to any fees paid to Tenant or any affiliate of Tenant. 
 (C) Landlord shall have no
obligation to pay Landlord’s Contribution in respect of any requisition submitted after the date which is one (1) year after the Fourth Amendment Commencement Date. 

(D) Tenant shall not be entitled to any unused portion of Landlord’s Contribution.

as used in the Lease shall refer to the Core Premises and the Fourth Amendment Additional Premises. 
  

	 	7.	ANNUAL FIXED RENT - FOURTH AMENDMENT TEMPORARY PREMISES

	 Three Month Bump Date through the Fourth Amendment Temporary Premises Expiration Date

 Notwithstanding

	 	8.	ANNUAL FIXED RENT - FOURTH AMENDMENT ADDITIONAL PREMISES

	 	9.	ANNUAL FIXED RENT - CORE PREMISES AND THIRD AMENDMENT ADDITIONAL PREMISES 


Except as specifically set forth herein (including but not limited to paragraph 3 above with regard to the Third Amendment Additional
Premises), the Rent for the aforesaid Core Premises and Third Amendment Additional Premises shall remain unchanged from that set forth in the Lease, including Articles 5, 6 and 7 thereof. Specifically, the parties agree that Tenant shall continue to
pay Fixed Rent with regard to the Core Premises pursuant to the terms of the Second Amendment through July 31, 2010. Notwithstanding the foregoing, as of August 1, 2010, the Annual Rate Per Rentable Square Foot paid by Tenant in connection
with the Core Premises shall be changed such that it shall be the same rate that Tenant is then paying in respect to the Fourth Amendment Additional Premises, as the same increases periodically (so that as of August 1, 2010, Tenant shall be
paying Annual Fixed Rent for the entirety Premises [i.e. the Core Premises and the Fourth Amendment Additional Premises] at the same rate). By way of example only, if Tenant is paying Annual Fixed Rent for the Fourth Amendment Additional Premises at
the Rent Year 2 rate (as that term is defined in paragraph 7 above) as of August 1, 2010 (i.e. $43.00 per rentable square foot), then Tenant would be obligated to pay Landlord a total of $75,687.16 in Fixed Rent for the month of August, 2010
(such sum representing $29,351.08 in connection with the Core Premises plus $46,336.08 in connection with the Fourth Amendment Additional Premises). 
  

	 	10.	OPERATING EXPENSES AND REAL ESTATE TAXES 


Effective as of the Fourth Amendment Additional Premises Commencement Date, the Sections 6.1(e) and 7.4(B) of Lease shall be amended such
that Base Taxes shall mean Landlord’s Tax Expenses for the fiscal tax year 2008 (that is the period beginning July 1,2007 and ending June 30, 2008), and Base Operating Expenses shall mean Operating Expenses for the Building for
calendar year 2008 (that is the period beginning January 1,2008 and ending December 31, 2008). 
  

 7 









	 	11.	ELECTRICITY 


Landlord will furnish electricity to the Fourth Amendment Temporary Premises and the Fourth Amendment Additional Premises through
presently installed electrical facilities for Tenant’s reasonable use for lighting, electrical appliances, heating, ventilation and air conditioning exclusively serving, as applicable, the Fourth Amendment Temporary Premises and the Fourth
Amendment Additional Premises and all other equipment. If Landlord provides such electricity, Tenant shall pay, as Additional Rent, for Fourth Amendment Temporary Period the sum of $8,700 per year (i.e. $1.50/rentable square foot, subject to the
terms hereof) in equal monthly installments with Base Rent, and for the Fourth Amendment Term the sum of $19,396.50 per year (i.e. $ 1.50/rentable square foot, subject to the terms hereof) in equal monthly installments with Base Rent. Said
Additional Rent shall be in addition to the Additional Rent paid by Tenant in connection with the other portions of the Premises then demised to Tenant, and shall subject to proportionate increase(s), from time to time and at any time throughout the
Term for the Fourth Amendment Temporary Premises and the Fourth Amendment Additional Premises, to the extent that the rate charged to Landlord by the utility company providing electricity to the Building is increased provided that Landlord, prior to
or simultaneous with increasing the Additional Rent, has. provided documentation to Tenant evidencing the increase in the electricity rate being charged to the Building by such utility company. Tenant agrees that, at Landlord’s sole option, an
electrical consultant, selected by Landlord, may make periodic surveys of the electrical equipment in the Fourth Amendment Temporary Premises and Fourth Amendment Additional Premises. In the event such survey(s) indicate that Tenant’s use of
electricity is greater than $1.50 per rentable square foot, the electricity charge shall be adjusted accordingly. Tenant shall continue to pay electricity charges with regard to the Third Amendment Additional Premises pursuant to the terms of the
Third Amendment. 
  

	 	12.	SECURITY DEPOSIT 


Effective as of the date hereof, the Security Deposit specified in Section 1.2 of the Lease, which is currently $24,810.00, shall be
increased by $284,978.12, to $309,789.00, which Security Deposit shall be held subject to the terms and conditions of this Lease, as modified by this Fourth Amendment. Notwithstanding the foregoing, provided that Tenant is not then in default, and
has not previously been in default, beyond the applicable notice and cure period, with respect to monetary obligations under the terms of this Lease, then effective as of first (1st) anniversary of the Fourth Amendment Additional Premises
Commencement Date, Tenant shall have the right to request that the Security Deposit be reduced by twenty percent (20%) to $247,831.00. On each of the next three such anniversaries of the Fourth Amendment Additional Premises Commencement Date,
provided Tenant is not then in default, under the terms of this Lease, and has not previously been in default, beyond the applicable notice and cure period, with respect to monetary obligations under the terms of this Lease, Tenant shall have the
right to request that the Security Deposit shall be reduced by an additional twenty percent (20%) of the initial deposit (i.e. by $61,958.00) each time (i.e., reduced to $185,874.00 on the second anniversary, to $123,916.00 on the third
anniversary, and to $61,958.00 on the fourth anniversary). In no event shall the Security and Restoration Deposit be reduced below the amount of $61,958.00. 

Provided that Tenant has satisfied the conditions precedent for each such reduction, Landlord shall, within thirty (30) days
following Tenant’s request for the reduction, return to Tenant the requisite amount of Security Deposit (to the extent that the same is held by Landlord 

 

 8 








 
as a cash security deposit). In the event that Tenant has elected pursuant to Section 16.26 of the Lease to provide a Letter of Credit, Tenant shall, upon satisfaction of the
above-referenced conditions, present to Landlord a substitute Letter of Credit that conforms with the terms of the Lease in the proper amount, following which Landlord shall return the Letter of Credit it was previously holding (if any) to Tenant.

  

	 	13.	MONETARY DEFAULT 


Section 15.1 (a) of the Lease is hereby deleted and the following substituted therefor: 

“Tenant shall fail to pay any installment of the Annual Fixed Rent, or any Additional Rent or any other monetary amount due under
this Lease on or before the date on which the same becomes due and payable, and such failure continues for ten (10) days after notice from Landlord thereof (provided, however, only for purposes of Section 16.26 of the Lease, as
modified by this Amendment, a default of monetary obligations shall mean the failure of Tenant to pay any installment of the Annual Fixed Rent, or any Additional Rent or any other monetary amount due under this Lease on or before the date on which
the same becomes due and payable, and such failure continues for five (5) days after notice from Landlord thereof); or” 
  

	 	14.	EXTENSION OPTION 


The Extension Option set forth in Section 3.2 of the Lease to extend the Term of the Lease for one (1) additional period of five
(5) years shall remain in full force and effect but is hereby amended to be a) effective only relative to the Core Premises and the Fourth Amendment Additional Premises, and b) exercisable not earlier than fifteen (15) months nor later
than twelve (12) months prior to the Fourth Amendment Additional Premises Expiration Date, in any event subject to the terms and conditions of Section 3.2 of the Lease. The parties hereby agree that except for said option, Tenant has no
further option to extend or renew the Term of this Lease as it pertains to any portion of the Premises. 
  

	 	15.	RIGHT OF FIRST OFFER 


Subject to the rights of existing tenants of the Building granted prior to the date hereof, and subject to any renewal or extension
granted to the then current tenant thereof, Tenant shall have a first right of offer (the “Right of First Offer”) on the Additional Space (as hereafter defined) during the Term and any extension thereof (the “Offer Period”)
on the terms and conditions hereinafter set forth. Before leasing such space to any third party during the Offer Period, Landlord shall notify Tenant of the anticipated availability during the Offer Period of any fourth (4th) floor space in the
Building not then leased by Tenant but contiguous to the Premises (the “Additional Space”), which notice (an “Offer Notice”) shall constitute an offer to Tenant to lease all of the Additional Space so offered pursuant to the
terms hereof. The Offer Notice shall identify the space available and the rental rate and other terms and conditions (collectively, the “Terms”) under which Landlord intends to offer such space to third parties. Tenant may exercise its
Right of First Offer by notifying Landlord within ten (10) days after receipt of an Offer Notice of Tenant’s election to lease the Additional Space. If Tenant elects to lease the 

 

 9 








 
Additional Space within the period provided, the lease of the Additional Space shall commence thirty (30) days after Tenant’s exercise of such election. The lease of the Additional
Space shall be upon all of the terms and conditions of this Lease, except that the Term thereof shall be coterminous with the Term under this Lease and shall be for no less than a twenty four (24) month term (a “Minimum Term”). If
the remaining Term of this Lease on the date of the Offer Notice is less than a Minimum Term, and Tenant’s Extension Option pursuant to Section 3.2 of the Lease is viable, then Tenant’s exercise of this Right of First Offer shall
constitute an exercise of Tenant’s Extension Option (as set forth in Section 3,2 of the Lease) and the Term for the Core Premises and Fourth Amendment Additional Premises shall be extended for five years pursuant to the Option to Extend
and the term for the Additional Space shall be coterminous therewith. The Base Rent for the Additional Space (and for the Initial Premises to the extent leased for any period beyond the Initial Term) shall be the rental rate set forth in
Landlord’s Offer Notice, it being understood that the Annual Fixed Rent shall be the Fair Market Rental Value as determined by Landlord. The Offer Period shall not include (i) the first twelve months of the Term nor (ii) any period
of time during which the remaining Term under this Lease is less than the Minimum Term and no Option to Extend pursuant to Section 3.2 hereof remains. 

Upon determination of the Base Rent for the Additional Space pursuant to the foregoing, the parties agree to execute an amendment to the
Lease acknowledging the same and setting forth the new Term for the Premises and the Additional Space. Subject to the terms of the Lease regarding construction on the Premises and if the Additional Space is then vacant, Tenant may enter the
Additional Space during the thirty (30) day period following Tenant’s election to lease the Additional Space for the purpose of making tenant improvements to the Additional Space, such use to be at no rental cost to Tenant; provided
however that if Tenant occupies the Additional Space for its intended purpose, the commencement date for the term for such Additional Space shall be deemed instead to be the occupancy date. If Tenant fails to elect timely to lease the Additional
Space, Landlord shall be entitled at any time thereafter and from time to time to lease the Additional Space to any party without need of notifying Tenant or reoffering the Additional Space to Tenant. 

In order for Tenant’s exercise of the Right of First Offer to be effective (or for Landlord’s duty to provide an Offer Notice
to exist) at the time of Landlord’s Offer Notice and at the time the term for the Additional Space is to commence, this Lease must be in full force and effect and Tenant shall not be in default at either time of any of the terms, covenants, or
conditions of this Lease beyond any applicable cure period; and provided further that Tenant must then be occupying at least seventy-five (75%) percent of the Premises and has not sublet any of the Premises or assigned this Lease.

	  	4,951 square feet


(B) As of the Sixth Amendment Additional Premises Commencement Date, Tenant is entitled to an increase in the number of parking
privileges such that Tenant shall have a total of twenty-nine (29) parking spaces, which spaces shall be available to Tenant pursuant to the terms and provisions of the Lease, including but not limited to payment of the monthly charge therefor,
currently $200.00 per space per month. As of the Current Termination Date, the number of parking spaces to which Tenant shall be entitled pursuant to the terms and conditions of the Lease shall automatically reduce to five (5) spaces.

  

	 	10.	TERMINATION OPTION 


(A) Notwithstanding anything to the contrary contained herein, effective as of the date which is the third anniversary of the Sixth
Amendment Additional Premises Commencement Date (the “Termination Date”), Tenant shall have, as to the Sixth Amendment Additional Premises only, a one-time option to terminate the Lease (a “Termination Option”), upon the
following terms and conditions. If Tenant desires to exercise the Termination Option, Tenant shall give Landlord written notice (a “Termination Notice”) of Tenant’s exercise of this

  

 5 








 
Termination Option on or before the date which is nine (9) months prior to the Termination Date (the “Notice Date”). Time is of the essence of this provision and such exercise,
once given, shall be irrevocable. Notwithstanding the foregoing, if at any time after Tenant’s exercise of this Termination Option, up to and including the Termination Date, Tenant shall be in Monetary Default, beyond applicable notice and
grace periods, if any, of the Lease, then Landlord may elect, but is not obligated, to cancel and declare null and void Tenant’s exercise of this Termination Option, and, after applying same to any outstanding monetary defaults, Landlord shall
return the Termination Fee (as defined below) and the Lease shall continue in full force and effect for the full Lease Term hereof unaffected by Tenant’s exercise of this Termination Option. If Landlord does not cancel Tenant’s exercise of
the Termination Option after Tenant’s Default, Tenant shall cure any Default within the period specified in the Lease and this obligation shall survive the Termination Date. In the event that Tenant gives the Termination Notice on a timely
basis, and all other conditions of exercise of this Termination Option are satisfied, the Lease shall terminate at 5:00 p.m. on the Termination Date. In order for such Termination Notice to be effective, such notice must be accompanied by the
termination fee (“Termination Fee”), which termination fee shall be calculated pursuant to the following formula: Termination Fee = (Landlord’s. Cost + Accrued Interest). As used herein, “Landlord’s Costs” shall mean
the unamortized portion of all actual third-party expenses paid by Landlord associated with the Lease including, without limitation, tenant improvement costs, brokerage and legal fees. Based on the foregoing, the Termination Fee shall be $73,830.43
(2/5 of the sum of $142,984.88 Landlord Contribution, $5,000 legal fees, $14,853.00 broker’s fee, plus accrued interest). “Accrued Interest” shall mean the sum of interest that would be payable during the period from the Rent
Commencement Date through the Termination Date with respect to a fully-amortizing loan assuming level payments of principal and interest where the principal amount equals Landlord’s Cost, the annual rate of interest equals eight percent
(8%) and the term is five years. The Termination Fee shall be payable with the Termination Notice by check, in cash or certified funds. Tenant’s obligations to pay Rent, Additional Rent, and any other costs and charges under this Amendment
and under the Lease, and to perform all other Lease obligations for the period up to and including the Termination Date, shall survive the termination of this Amendment. In the event Tenant exercises the Termination Option, Tenant covenants and
agrees to surrender full and complete possession of the Premises to Landlord on or before the Termination Date in compliance with the requirements of Section 16.5 of the Lease. If Tenant shall fail to deliver possession of the Sixth Amendment
Additional Premises on or before the Termination Date in accordance with the terms hereof, Tenant shall be deemed to be a holdover tenant subject to the remedies set forth in the Lease. If Tenant properly and timely exercises the Termination Option
and (if Landlord elects to apply such condition) no Event of Default exists either at the time of Tenant’s exercise of the Termination Option or on the Termination Date, the lease of the Sixth Amendment Additional Premises shall cease and
expire on the Termination Date with the same force and effect as if said Termination Date were originally provided in this Amendment as the Sixth Amendment Additional Premises Expiration Date. Notwithstanding anything contained herein to the
contrary, a Permitted Tenant Successor and/or Tenant Affiliate shall have the right to exercise the Termination Option pursuant to this Section.

	 	11.	BROKER 

 (A) Tenant
warrants and represents that Tenant has not dealt with any brokers in connection with the consummation of this Sixth Amendment other than Cushman & Wakefield of Massachusetts, Inc. and CresaPartners (“Brokers”). In the event that
any claim is made against the Landlord relative to Tenant’s dealings with brokers other than the Brokers, Tenant ,# shall defend the claim against Landlord with counsel of Tenant’s selection, subject to Landlord’s reasonable approval,
and save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim. 
 (B)
Landlord warrants and represents that Landlord has not dealt with any brokers in connection with the consummation of this Sixth Amendment other than Brokers; and in the event any claim is made against the Tenant relative to Landlord’s dealings
with brokers other than the Brokers, Landlord shall defend the claim against Tenant with counsel of Tenant’s selection and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim.

 (C) Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the Broker.

	4.	PLANS

B. Cost Proposal. Tenant shall advise Landlord of price estimates (including breakdowns by trade) as promptly as possible but in any event
within twenty (20) business days after Landlord’s receipt of the Plans. Tenant shall calculate and furnish to Landlord a “Cost Proposal” which shall constitute the aggregate of (i) the amounts payable under the subcontracts
selected (and, where the General Contractor is performing work that would be performed by a subcontractor, the cost of such work) in the bid process, broken down by trade (“Direct Costs”), and (ii) the amount of the General

 D. Change Orders. Tenant shall have the right to submit for Landlord’s approval (which shall not be unreasonably
withheld) change proposals subsequent to Landlord’s approval of the Plans and the Cost Proposal (each, a “Change Proposal”). Landlord agrees to respond to any such Change Proposal (which response shall include any information
necessary for Tenant to evaluate such Change Proposal) within 3 business days after the submission thereof by Tenant, advising Tenant of any anticipated costs (“Change Order Costs”) associated with such Change Proposal, as well as an
estimate of any delay which would likely result. Tenant shall have the right to then approve or withdraw such Change Proposal within five (5) business days after receipt of such information; if approved, it shall become a Change Order, and the
Change Order Costs associated with it shall be deemed additions to the Cost Proposal. 
 E. Cost of Tenant Improvement Work. The
Tenant Improvement Work shall, subject to Landlord’s Contribution (as defined in Section 2 of this Amendment and referred to in Section 8 hereof), be performed at Tenant’s sole cost and expense. If the cost of the Tenant

workmanship and materials (“Tenant’s Warranty”). Tenant’s Warranty shall be subject to the exclusions which are set forth in Section 3.5.1 of the form A201 General Conditions published by the American Institute of Architects
(1997 edition). Tenant’s obligations under this Section 7(B) shall only apply during the Warranty Period, as hereinafter defined. The “Warranty Period” shall be twelve months after the Sixth Amendment Additional Premises
Commencement Date; however, Tenant agrees to notify Landlord promptly after Tenant’s discovery of any alleged defect. The Warranty Period shall apply to any defect which Tenant either discovers or of which Landlord notifies Tenant during such
Warranty Period. Tenant agrees to correct or repair, at Tenant’s expense, items which are in breach of Tenant’s Warranty or which otherwise are incomplete or do not conform to the work contemplated or to Tenant’s Plans.
