hereby demises and leases to Tenant, and Tenant hereby hires and accepts from Landlord, Tenant’s Premises in the Building excluding exterior faces of exterior walls, the common stairways and stairwells, elevators and elevator wells, fan rooms,

the entire rentable area of any floor, excluding the common corridors, elevator lobbies and toilets located on such floor.

	2.2	Rights to Use Common Facilities 

 Subject to Landlord’s right to change or alter any of the following in Landlord’s discretion as herein provided, Tenant shall have, as appurtenant to the Premises, the non- exclusive right to
use in common with others, subject to reasonable rules of general applicability to tenants of the Building from time to time made by Landlord of which Tenant is given notice (a) the common lobbies, corridors, stairways, elevators and loading

provider of fees assessed by Landlord in its sole discretion. 
  

	 	2.2.1	Tenant’s Parking 

In addition, Tenant shall have the right to use in the parking area the Number of Parking Spaces (referred to in Section 1.1) for
the parking of automobiles, in common with use by other tenants from time to time of the Complex, provided, however, that Landlord shall not be obligated to furnish stalls or spaces on the Site specifically designated for Tenant’s use. In the
event that the Rentable Floor Area of the Premises decreases at any time during the Lease Term, the Number of Parking Spaces provided to Tenant hereunder shall be reduced proportionately. Tenant covenants and 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 with respect to the use of the parking areas on the Site. The parking privileges granted herein, are non-transferable. Further,
Landlord assumes no responsibility whatsoever for loss or damage due to fire, theft or otherwise to any automobile(s) parked on the Site or to any personal property therein, however caused (except to the extent caused by the gross negligence or
willful misconduct of Landlord, its agent or employees), and Tenant covenants and agrees, upon request from Landlord from time to time, to notify its officers, employees, agents and invitees of such limitation of liability. Tenant acknowledges and
agrees that a license only is hereby granted, and no bailment is intended or shall be created. 
  

	2.3	Landlord’s Reservations 

 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

 Tenant shall
have and hold the Premises for a period commencing on the earlier of (a) that date on which the Premises are ready for occupancy as defined in Section 3.1 and Exhibit B-1 hereof, or (b) that date on which Tenant commences
occupancy of any portion of the Premises for the Permitted Uses (it being agreed that Tenant’s exercise of its early access right under Section 1.1(B)(4) of Exhibit B-1 shall not be deemed to be commencement of occupancy for purposes of

(5) business days advance written notice of the date on which the Premises shall be ready for occupancy as defined in Section 3.1 and Exhibit B-1 hereof. 
 As soon as may be convenient after the date has been determined on which the Term commences as aforesaid, Landlord and Tenant agree to join with each other in the execution of a written Declaration, in
the form of Exhibit E, in which the date on which the Term commences as aforesaid and the Term of this Lease shall be stated. If Tenant fails to execute such Declaration, the Commencement Date and Lease Term shall be as reasonably determined by
Landlord in accordance with the terms of this Lease. 
  

	2.5	Fixed Rent Payments 

 Tenant agrees to pay to Landlord, (1)(a) on the Phase I Rent Commencement Date (defined in Section 1.1 hereof) and thereafter monthly, in advance, on the first day of each and every calendar
month during the Original Term, a sum equal to one twelfth (1/12th) of the Annual Fixed Rent (sometimes hereinafter referred to as “fixed rent”) and (1)(b) on the Commencement Date and thereafter monthly, in advance, on the first day of each and
every calendar month during the Original Term, an amount estimated by Landlord from time to time to cover Tenant’s monthly payments for electricity under Section 2.8 hereinbelow and (2) on the first day of each and every calendar
month during extension option period (if exercised), a sum equal to (a) one twelfth (1/12th) of the annual fixed rent as determined in Section 9.18 for the extension option period plus (b) then applicable monthly electricity charges (subject to escalation for electricity as

 9 

 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 Phase I Rent Commencement Date is a day 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 Phase I Rent Commencement Date to the first day of the succeeding calendar month. 
 Additional Rent payable by Tenant on a monthly basis, as hereinafter provided, likewise shall be prorated, and the first payment on account thereof shall be determined in similar fashion but shall
commence on the Commencement Date; and other provisions of this Lease calling for monthly payments shall be read as incorporating this undertaking by Tenant. 
 Notwithstanding that the payment of Annual Fixed Rent payable by Tenant to Landlord shall not commence until the Phase I Rent Commencement Date, Tenant shall be subject to, and shall comply with, all
other provisions of this Lease as and at the times provided in this Lease. 
 The Annual Fixed Rent and all other charges for
which provision is herein made shall be paid by Tenant to Landlord, without offset, deduction or abatement except as otherwise specifically set forth in this Lease. 
 Notwithstanding anything contained herein or in Section 1.1 to the contrary, it is understood and agreed that in the event Tenant shall default in its obligations under this Lease beyond applicable
notice and cure periods at any time during the Term of this Lease, and Landlord terminates this Lease as a result thereof (but such default need not be the exclusive reason for such termination), Annual Fixed Rent for the period commencing on the
Commencement Date and ending on the Phase I Rent Commencement Date as well as the abated Annual Fixed Rent from the period running from the Phase I Rent Commencement Date through the Phase II Rent Commencement Date shall immediately become due and
payable in the amount of $159,831.33.

all other reasonable and necessary expenses paid in connection with the operation, cleaning and maintenance of the Building and the Site and properly chargeable against income, provided, however, there shall be included (a) depreciation for
capital expenditures made by Landlord during the Lease Term (i) to reduce Landlord’s Operating Expenses if Landlord shall have reasonably determined that the annual reduction in Landlord’s Operating Expenses shall exceed depreciation

subsections (i) and (ii) being hereinafter referred to as “Permitted Capital Expenditures”); plus (b) in the case of both (i) and (ii) 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 locality in which the Building is located; depreciation in the case of both (i) and (ii) shall be determined by dividing the original cost of

reasonable time after Landlord timely receives the notice from Tenant to make such examination pursuant to this 

  
 14 

 
Section, either electronically or during normal business hours at the offices where Landlord keeps such books and records or at another location, as determined by Landlord. 

4. Tenant shall have the right to make such examination no more than once in respect of any Operating Year in which Landlord has given
Tenant a statement of the Landlord’s Operating Expenses.

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. 

7. No subtenant shall have any right to conduct any such examination and no assignee may conduct any such examination with respect to any
period during which the assignee was not in possession of the Premises.

Notice”), which date shall not be earlier than sixty (60) days nor later than one hundred and twenty (120) days after Landlord’s notice to Tenant; provided, however,

 that upon the termination date as set forth in Landlord’s notice, all obligations relating to the period
after such termination date (but not those relating to the period before such termination date) shall cease and promptly upon being billed therefor by Landlord, Tenant shall make final payment of all Annual Fixed Rent and Additional Rent due from
Tenant through the termination date. In the event that Landlord shall not exercise its termination rights as aforesaid, or shall fail to give any or timely notice pursuant to this Section the provisions of Sections 5.6.3, 5.6.5 and 5.6.6 shall be
applicable. In the event Landlord sends a Termination Notice, Tenant shall have the right within five (5) days of receipt of the same to rescind Tenant’s Proposed Transfer Notice (the “Rescission Notice”), and in the event Tenant
delivers a Rescission Notice, Landlord’s Termination Notice shall be null and void and this Lease shall continue in effect as though the same were not sent; provided, however, that Tenant shall have the right to send a Rescission Notice only
once during any twelve-month period. This Section 5.6.2 shall not be applicable to an assignment or sublease pursuant to Section 5.6.4. 
  

	 	5.6.3	Notwithstanding the provisions of Section 5.6 above, but subject to the provisions of this Section 5.6.3 and the provisions of Sections 5.6.5 and 5.6.6 below,
in the event that Landlord shall not have exercised the termination right as set forth in Section 5.6.2, or shall have failed to give any or timely notice under Section 5.6.2, then for a period of one hundred and twenty (120) 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, in the event Landlord shall not give any or timely notice under
Section 5.6.2 as the case may be, Tenant shall have the right to assign this Lease or sublet the whole (but not part) of the Premises in accordance with the Proposed Transfer Notice 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 elsewhere on the Site, except where such tenant is increasing the size of its existing premises and
Landlord has no available space in the Building or on the Site to accommodate such expansion, or is in active negotiation with Landlord or an affiliate of Landlord for premises in the Building or elsewhere on the Site 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 

  
 24 

	 	(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 1.1 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
Landlord’s Operating Expenses 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 generated by normal and customary office
usage; 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 7.1) or there have been three (3) or more Event of Default occurrences during the Term, or

  

	 	(g)	the proposed rent and other charges to be payable by the proposed assignee or subtenant are less than the sublet market rent and other charges for first class office
space for properties of a similar character in the Boston West Suburban market, or 

  

	 	(h)	any part of the rent payable under the proposed assignment or sublease shall be based in whole or in part on the income or profits derived from the Premises or if any
proposed assignment or sublease shall potentially have any adverse effect on the real estate investment trust qualification requirements applicable to Landlord and its affiliates, or 

 

	 	(i)	the holder of any mortgage or ground lease on property which includes the Premises does not approve of the proposed assignment or sublease, provided such mortgagee or
ground lessor has a right to so approve pursuant to its documentation with Landlord or an affiliate of Landlord, or 

  

	 	(j)	due to the identity or business of a proposed assignee or subtenant, such approval would cause Landlord to be in violation of any covenant or restriction contained in
another lease or other agreement affecting space in the Building or elsewhere in the Property. 

 If Landlord
shall consent to the proposed assignment or subletting, as the case may be, then, in such event, Tenant may thereafter sublease (the whole but not 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 

  
 25 

 Landlord within ninety (90) days after the date of Landlord’s consent, the
consent shall be deemed null and void and the provisions of Section 5.6.1 shall be applicable. 
  

	 	5.6.4	Notwithstanding the foregoing provisions of Sections 5.6, 5.6.2, 5.6.3 and 5.6.5, but subject to the provisions of Sections 5.6.1 and 5.6.6, Tenant shall have the
right without the consent of Landlord to assign this Lease or to sublet the Premises (in whole or in part) to any other entity (the “Successor Entity”) (i) which controls or is controlled by Tenant or Tenant’s parent corporation,
or (ii) which is under common control with Tenant, or (iii) which purchases all or substantially all of the assets of Tenant, or (iv) which purchases a majority of the stock of (or other ownership or membership interests in) Tenant or
(v) which merges or combines with Tenant, provided that the entity to which this Lease is so assigned or which so sublets the Premises has a credit worthiness (e.g. net assets on a pro forma basis using generally accepted accounting principles
consistently applied and using the most recent financial statements) which is the same or better than the Tenant as of the date of this Lease (the foregoing transferees referred to, individually or collectively, as a “Permitted
Transferee”). Except in cases of statutory merger, in which case the surviving entity in the merger shall be liable as the Tenant under this Lease, Tenant shall continue to remain fully liable under this Lease, on a joint and several basis with
the Permitted Transferee to whom the Lease is actually assigned or the Premises sublet. If any parent, affiliate or subsidiary of Tenant to which this Lease is assigned or the Premises sublet (in whole or in part) shall cease to be such a parent,
affiliate or subsidiary, such cessation shall be considered an assignment or subletting requiring Landlord’s consent. 

  

	 	5.6.5	In the case of any assignment or subleasing as to which Landlord may consent (other than an assignment or subletting permitted under Section 5.6.4 above) 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 and Additional Rent and other charges provided in this Lease (provided, however, that for the purpose of calculating the Assignment/Sublease Profits in the case of a sublease, appropriate
prorations 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 be limited to brokerage commissions and alteration allowances, in each case actually paid), 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. 

  
 26 

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

	 	5.6.6	(A) It shall be a condition of the validity of any assignment or subletting consented to under Section 5.6.3 above, or any assignment or subletting of right
under Section 5.6.4 above, that both Tenant and the assignee or sublessee enter into a separate written instrument directly with Landlord in a form and containing terms and provisions reasonably required by Landlord, including, without
limitation, the agreement of the assignee or sublessee to be bound directly to Landlord for all the obligations of the Tenant under this Lease (including any amendments or extensions thereof), including, without limitation, the obligation
(a) to pay the rent and other amounts provided for under this Lease (but in the case of a partial subletting pursuant to Section 5.6.4, such subtenant shall agree on a pro rata basis to be so bound), (b) to comply with the provisions
of Sections 5.6 through 5.6.6 hereof and (c) to indemnify the “Landlord Parties” (as defined in Section 8.13) as provided in Section 8.1 hereof. Such assignment or subletting shall not relieve the Tenant named herein of any
of the obligations of the Tenant hereunder and Tenant shall remain fully and primarily liable therefor and the liability of Tenant and such assignee (or subtenant, as the case may be) shall be joint and several. Further, and notwithstanding the
foregoing, the provisions hereof shall not constitute a recognition of 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 sublease shall be terminated. 

 (B) As Additional Rent, Tenant shall pay to Landlord as a fee for Landlord’s review of any proposed assignment or sublease requested by Tenant and the preparation of any associated documentation in
connection therewith, within thirty (30) days after receipt of an invoice from Landlord, an amount equal to the sum of (i) $1,000.00 and/or (ii) reasonable out of pocket legal fees or other expenses incurred by Landlord in connection
with such request. 
 (C) If this Lease be assigned, or 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 and from time to time, collect rent and other charges from the assignee, sublessee or occupant and apply the net amount collected to the rent and other charges herein reserved,
but no such assignment, subletting, occupancy or collection shall be deemed a waiver of this covenant, or a waiver of the provisions of Sections 5.6 through 5.6.6 hereof, or the acceptance of the assignee, 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) The consent by Landlord to an assignment or subletting under Section 5.6.3 above, or the consummation of an assignment or
subletting of right under Section 

  
 27 

 
5.6.4 above, shall in no way be construed to relieve Tenant from obtaining the express consent in writing of Landlord to any further assignment or subletting. 

(E) On or after the occurrence of an “Event of Default” (defined in Section 7.1), Landlord shall be entitled to one
hundred percent (100%) of any Assignment/Sublease Profits. 
 (F) Without limiting Tenant’s obligations under
Section 5.12, 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 work in connection with such assignment or subletting. 
  

	5.7	Right of Entry 

 To permit
Landlord and its agents to examine the Premises at reasonable times and upon prior verbal or written notice (except in the event of emergency, in which event no notice shall be required) and, if Landlord shall so elect, to make any repairs or
replacements Landlord may deem necessary; to remove, at Tenant’s expense, any alterations, addition, signs, curtains, blinds, shades, awnings, aerials, flagpoles, or the like not consented to in writing; and to show the Premises to prospective
tenants during the eleven (11) months preceding expiration of the Term and to prospective purchasers and mortgagees at all reasonable times. 
  

	5.8	Floor Load; Prevention of Vibration and Noise 

 Not to place a load upon the Premises exceeding an average rate of 70 pounds of live load per square foot of floor area (partitions shall be considered as part of the live load); 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 which cause vibration or noise that may be
transmitted to the Building structure or to any other space in the Building shall be so installed, maintained and used by Tenant so as to eliminate such vibration or noise. 

 

	5.9	Personal Property Taxes 

To pay promptly when due all taxes which may be imposed upon “Tenant’s Property” (as defined in Section 8.4 hereof) in
the Premises to whomever assessed. 
  

	5.10	Compliance with Laws 

 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 Building unless the same are required by such Legal Requirements as a result of or in
connection with Tenant’s use or occupancy of the Premises 

  
 28 

 
beyond normal use of space of this kind. 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 5.10. Notwithstanding the foregoing, Landlord at Landlord’s expense, shall be responsible for the work described in Exhibit B-1 complying on the Commencement Date with the requirements of the Federal Americans With
Disabilities Act (the “ADA”) in effect on the Commencement Date; provided, however, that notwithstanding the foregoing, Tenant at Tenant’s expense, shall be responsible for (i) any additions, alterations or improvements performed
by or for Tenant or any assignee of subtenant of Tenant (“Tenant Improvements”) complying with the ADA and (ii) compliance with the ADA required because of “Tenant’s Specific Use of the Premises” (as defined below) or
Tenant Improvements. The term “Tenant’s Specific Use of the Premises” as used in this Lease shall not refer to the general office use of the Premises, but shall refer to the specific products and operations Tenant and any assignee and
subtenant of Tenant use in the Premises and the manner in which Tenant and any assignee and subtenant of Tenant use such products and conduct such operations. 
 To the best of Landlord’s actual knowledge, the Building was constructed in accordance with the provisions of the Zoning Code for the City of Burlington and other laws, ordinances, rules and
regulations applicable to the Building as of the construction of the Building. 
  

	5.11	Payment of Litigation Expenses 

 As Additional Rent, to pay all reasonable costs, counsel and other fees incurred by Landlord in connection with the successful enforcement by Landlord of any obligations of Tenant under this Lease or in
connection with any bankruptcy case involving Tenant or any guarantor. Landlord hereby similarly agrees to pay all reasonable costs, counsel and other fees incurred by Tenant in connection with the successful enforcement by Tenant of any obligations
of Landlord under this Lease or in connection with any bankruptcy case involving Landlord. 
  

	5.12	Alterations 

 Tenant shall
not make alterations and additions to Tenant’s Premises except in accordance with plans and specifications therefor first approved by Landlord, which approval shall not be unreasonably withheld. 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 for
withholding approval of any alterations or additions (including, without limitation, any alterations or additions to be performed by Tenant under Article III) which (a) in Landlord’s opinion might 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 (b) involve or affect the exterior design, size,
height, or other exterior dimensions of the Building or (c) will require unusual expense to readapt the Premises to normal office use on Lease termination or expiration or increase the cost of construction or of insurance or taxes on the
Building or of the services called for by Section 4.1 unless Tenant first gives assurance acceptable to Landlord for payment of such increased cost and that such readaptation will be 

  
 29 

 
made prior to such termination or expiration without expense to Landlord, (d) enlarge the Rentable Floor Area of the Premises, or (e) are inconsistent, in Landlord’s judgment, with
alterations satisfying Landlord’s standards for new alterations in the Building. Landlord’s review and approval of any such plans and specifications 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 and the other requirements of this Lease with respect to Tenant’s insurance obligations (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 nor give right to any other parties. Further, Tenant acknowledges that Tenant is acting for its own
benefit and account, and that Tenant shall not be acting as Landlord’s agent in performing any work in the Premises, accordingly, no contractor, subcontractor or supplier shall have a right to lien Landlord’s interest in the Property in
connection with any work. Within thirty (30) days after receipt of an invoice from Landlord, Tenant shall pay to Landlord as a fee for Landlord’s review of any work or plans (excluding any review respecting initial improvements performed
pursuant to Article III hereof for which a fee has previously been paid but not including any review of plans or work relating to any assignment or subletting), as Additional Rent, an amount equal to the sum of (i) $150.00 per hour, plus
(ii) third party expenses incurred by Landlord to review Tenant’s plans and Tenant’s work. Except for any additions or alterations which Tenant requests to remain in the Premises in Tenant’s notice seeking Landlord’s consent
for the installation thereof (which notice shall specifically refer to this Section 5.12) and for which Landlord specifically agrees in writing may remain, all alterations and additions shall be part of the Building unless and until Landlord
shall specify the same for removal pursuant to Section 5.2. All of Tenant’s alterations and additions and installation of furnishings shall be coordinated with any work being performed by Landlord and in such manner as to maintain
harmonious labor relations and not to damage the Buildings or Site or interfere with construction or operation of the Buildings and other improvements to the Site and, except for installation of furnishings, shall be performed by Landlord’s
general contractor or by contractors or workers first approved by Landlord. Except for work by Landlord’s general contractor, Tenant, before its work is started, shall secure all licenses and permits necessary therefor; deliver to Landlord a
statement of the names of all its contractors and subcontractors and the estimated cost of all labor and material to be furnished by them and security satisfactory to Landlord protecting Landlord against liens arising out of the furnishing of such
labor and material; and cause each contractor to carry insurance in accordance with Section 8.14 herein and to deliver to Landlord certificates of all such insurance. Tenant shall also prepare and submit to Landlord a set of as-built plans, in
both print and electronic forms, showing such work performed by Tenant to the Premises promptly after any such alterations, improvements or installations are substantially complete and promptly after any wiring or cabling for Tenant’s computer,
telephone and other communications systems is installed by Tenant or Tenant’s contractor. Without limiting any of Tenant’s obligations hereunder, Tenant shall be responsible, as Additional Rent, for the costs of any alterations, additions
or improvements in or to the Building that are required in order to comply with Legal Requirements as a result of any work performed by Tenant. Landlord shall have the right to provide such rules and 

  
 30 

 
regulations relative to the performance of any alterations, additions, improvements and installations by Tenant hereunder and Tenant shall abide by all such reasonable rules and regulations and
shall cause all of its contractors to so abide including, without limitation, payment for the costs of using Building services. Tenant agrees to pay promptly when due the entire cost of any work done on the Premises by Tenant, its agents, employees,
or independent 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 Buildings or the Site and immediately to discharge any such liens which may so
attach. Tenant shall pay, as Additional Rent, 100% of any real estate taxes on the Complex which shall, at any time after commencement of the Term, result from any alteration, addition or improvement to the Premises made by Tenant. Tenant
acknowledges and agrees that Landlord shall be the owner of any additions, alterations and improvements in the Premises or the Building to the extent paid for by Landlord. 
 Notwithstanding the terms of this Section 5.12, Tenant shall have the right, without obtaining the prior consent of Landlord but upon prior notice to Landlord, to make alterations, additions or
improvements to the Premises 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 (including no signs on windows);

  

	 	(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 cost of any individual alteration, addition or improvement shall not exceed $30,000.00 and the aggregate cost of said alterations, additions or improvements made by
Tenant during the Lease Term shall not exceed $120,000.00 in cost; 

  

	 	(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; and 

 provided, however, that Tenant shall, within fifteen (15) days after the making of such
changes, send to Landlord plans and specifications describing the same in reasonable detail and provided further that Landlord, by notice to Tenant given at least thirty (30) days prior to the expiration or earlier termination of the Lease
Term, may require Tenant to restore the Premises to its condition prior to such alteration, addition or improvement at the expiration or earlier termination of the Lease Term. 

 

	5.13	Vendors 

 Any vendors
engaged by Tenant to perform services in or to the Premises including, without limitation, janitorial contractors and moving contractors 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 the Property or interfere with Building construction or operation and shall be performed by vendors first approved by Landlord. 

  
 31 

	5.14	Patriot Act 

 As an
inducement to Landlord to enter into this Lease, Tenant hereby represents and warrants that: (i) Tenant is not, nor is it owned or controlled directly or indirectly by, any person, group, entity or nation named on any list issued by the Office
of Foreign Assets Control of the United States Department of the Treasury (“OFAC”) pursuant to Executive Order 13224 or any similar list or any law, order, rule or regulation or any Executive Order of the President of the United States as
a terrorist, “Specially Designated National and Blocked Person” or other banned or blocked person (any such person, group, entity or nation being hereinafter referred to as a “Prohibited Person”); (ii) Tenant is not (nor is
it owned, controlled, directly or indirectly, by any person, group, entity or nation which is) acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) from and after the effective date of the above-referenced
Executive Order, Tenant (and any person, group, or entity which Tenant controls, directly or indirectly) has not conducted nor will conduct business nor has engaged nor will engage in any transaction or dealing with any Prohibited Person in
violation of the U.S. Patriot Act or any OFAC rule or regulation, including without limitation any assignment of this Lease or any subletting of all or any portion of the Premises or the making or receiving of any contribution of funds, goods or
services to or for the benefit of a Prohibited Person in violation of the U.S. Patriot Act or any OFAC rule or regulation. In connection with the foregoing, it is expressly understood and agreed that (x) any breach by Tenant of the foregoing
representations and warranties shall be deemed an immediate Event of Default by Tenant under Section 7.1 of this Lease (without the benefit of notice or grace) and shall be covered by the indemnity provisions of Section 8.1 below, and
(y) the representations and warranties contained in this subsection shall be continuing in nature and shall survive the expiration or earlier termination of this Lease. 
 ARTICLE VI 
 Casualty and Taking 

 

	6.1	Damage Resulting From Casualty 

 In case during the Lease Term the Building or the Site are damaged by fire or casualty and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within one
hundred twenty (120) days from the time that repair work would commence, Landlord may, at its election, terminate this Lease by notice given to Tenant within sixty (60) days after the date of such fire or other casualty, specifying the
effective date of termination. The effective date of termination specified by Landlord shall not be less than thirty, (30) days nor more than forty-five (45) days after the date of notice of such termination. 

In case during the last year of the Lease Term, the Premises are damaged by fire or casualty and such fire or casualty damage cannot, in
the ordinary course, reasonably be expected to be repaired within one hundred fifty (150) days (and/or as to special work or work which requires long lead time then if such work cannot reasonably be expected to be repaired within such
additional time as is reasonable under the circumstances given the nature of the work) 

  
 32 

 
from the time that repair work would commence, Tenant may, at its election, terminate this Lease by notice given to Landlord within sixty (60) days after the date of such fire or other
casualty, specifying the effective date of termination. The effective date of termination specified by Tenant shall be not less than thirty (30) days nor more than forty-five (45) days after the date of notice of such termination.

 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. 
 If the Building or the Site or any part thereof are damaged by fire or
other casualty and this Lease is not so terminated, or Landlord or Tenant have no right to terminate this Lease, and in any 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 Site as part of the demised premises allows the net insurance proceeds to be applied to the restoration of the Building (and/or the Site), 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 (excluding “Tenant’s Property” (as defined in Section 8.4 hereof), except as expressly
provided in the immediately following paragraph of this Section 6.1) into proper condition for use and occupation and a just proportion of the Annual Fixed Rent, Tenant’s share of Operating Expenses and Tenant’s share of real estate
taxes according to the nature and extent of the injury to the Premises shall be abated until the Premises shall have been put by Landlord substantially into such condition except for punch list items and long lead items. Notwithstanding anything
herein contained to the contrary, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net insurance proceeds. 
 Notwithstanding the foregoing, if Landlord is proceeding with the restoration of the Building and the Premises in accordance with the previous paragraph, Landlord shall also restore any alterations,
additions or improvements within the Premises that are part of Tenant’s Property (x) which have previously been approved by Landlord in accordance with the terms and provisions of this Lease and (y) with respect to which Tenant has
carried “all risk” insurance covering the loss or damage in accordance with Section 8.4 below and pays the proceeds of such insurance (or an amount equivalent thereto) to Landlord within five (5) business days following
Landlord’s written request; provided, however, that in no event shall Landlord be required to fund any insufficiency in the insurance proceeds (or equivalent amount) provided by Tenant with respect to such loss or damage (or to fund any of the
costs of restoration in the absence of any payment by Tenant). 
 Unless such restoration is completed
within ten (10) months from the date of the casualty or taking, such period to be subject, however, to extension where the delay in completion of such work is due to Force Majeure, as defined hereinbelow, (but in no event beyond sixteen
(16) months from the date of the casualty or taking), Tenant, as its sole and exclusive remedy, shall have the right to terminate this Lease at any time after the expiration of such ten-month (as extended) period until the restoration is
substantially completed, such termination to take effect as of the thirtieth (30th) day after the date of receipt by Landlord of Tenant’s notice, with the same force and effect as if such date were the date originally established as the expiration date hereof unless, within
thirty (30) days after Landlord’s 

  
 33 

 
receipt of Tenant’s notice, such restoration is substantially completed, in which case Tenant’s notice of termination shall be of no force and effect and this Lease and the Lease Term
shall continue in full force and effect. When used herein, “Force Majeure” shall mean any prevention, delay or stoppage 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. 

If the Building or the Site or any part thereof are damaged by fire or other casualty and this Lease is not so terminated by Landlord as
provided herein, Landlord promptly after such damage shall use due diligence to restore the Premises and the Building in the event of damage thereto (excluding Tenant’s Property) into proper condition for use and occupation and a just
proportion of the Annual Fixed Rent, Tenant’s share of Operating Expenses, Tenant’s share of real estate taxes and Tenant’s payments for electricity according to the nature and extent of the injury to the Premises shall be abated
until the Premises shall have been put by Landlord substantially into such condition except for punch list items and long lead items 
  

	6.2	Uninsured Casualty 

Notwithstanding anything to the contrary contained in this Lease, if 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 at the time maintained by Landlord and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within ninety (90) days
from the time that repair work would commence, Landlord may, at its election, terminate the Term of this Lease by notice to the Tenant given within sixty (60) days after such loss. 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. 
  

	6.3	Rights of Termination for Taking 

 If the entire Building, or such portion of the Premises as to Tender 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.

 Further, if so much of the Building shall be so taken that continued operation of the Building would be uneconomic as a result
of the taking, 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. 

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 lease which includes the Site 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. 
 If the
Premises shall be affected by any exercise of the power of eminent domain, then the Annual Fixed Rent, Tenant’s share of Operating Expenses and Tenant’s share of real estate taxes 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, Tenant’s share of operating costs and
Tenant’s share of real estate taxes shall be abated for the remainder of the Lease Term. 
  

	6.4	Award 

 Landlord shall
have and hereby reserves to itself any and all rights to receive awards made for damages to the Premises, the Buildings, the Complex and the Site and the leasehold hereby created, or any one or more of them, accruing by reason of exercise of eminent
domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby grants, releases and assigns to Landlord all Tenant’s rights to such awards, and covenants to execute and deliver such further assignments
and assurances thereof as Landlord may from time to time request, and if Tenant shall fail to execute and deliver the same within fifteen (15) days after notice from Landlord, Tenant hereby covenants and agrees that Landlord shall be
irrevocably designated and appointed as its attorney-in-fact to execute and deliver in Tenant’s name and behalf all such further assignments thereof which conform with the provisions hereof. 

Nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceeding a claim for the value of any
of Tenant’s usual trade fixtures installed in the Premises by Tenant at Tenant’s expense and for relocation and moving expenses, provided that such action and any resulting award shall not affect or diminish the amount of compensation
otherwise recoverable by Landlord from the taking authority.

 ARTICLE VII 
 Default 
  

	7.1	Tenant’s Default 

  

	 	(a)	If at any time subsequent to the date of this Lease any one or more of the following events (herein sometimes called an “Event of Default”) shall occur:

  

	 	(i)	Tenant shall fail to pay the fixed rent, Additional Rent or other charges for which provision is made herein on or before the date on which the same become due and
payable, and the same continues for five (5) days after notice from Landlord thereof; or 

  

	 	(ii)	Landlord having rightfully given the notice specified in subdivision (i) above twice in any calendar year, Tenant shall thereafter in the same calendar year fail
to pay the fixed rent, Additional Rent or other charges on or before the date on which the same become due and payable; or 

  

	 	(iii)	Tenant shall assign its interest in this Lease or sublet any portion of the Premises in violation of the requirements of Sections 5.6 through 5.6.5 of this Lease; or

  

	 	(iv)	Tenant shall neglect or fail to perform or observe any other covenant herein contained on Tenant’s part to be performed or observed and Tenant shall fail to remedy
the same within thirty (30) days after notice to Tenant specifying such neglect or failure, or if such failure is of such a nature that Tenant cannot reasonably remedy the same within such thirty (30) day period, Tenant shall fail to
commence promptly to remedy the same and to prosecute such remedy to completion with diligence and continuity; or 

  

	 	(v)	Tenant’s leasehold interest in the Premises shall be taken on execution or by other process of law directed against Tenant; or 

 

	 	(vi)	Tenant shall make an assignment for the benefit of creditors or shall file a voluntary petition in bankruptcy or shall be adjudicated bankrupt or insolvent, or shall
file any petition or answer seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief for itself under any present or future federal, state or other statute, law or regulation for the relief of
debtors, or shall seek or consent to or acquiesce in the appointment of any trustee, receiver or liquidator of Tenant or of all or any substantial part of its properties, or shall admit in writing its inability to pay its debts generally as they
become due; or 

  
 36 

	 	(vii)	A petition shall be filed against Tenant in bankruptcy or under any other law seeking any reorganization, arrangement, composition, readjustment, liquidation,
dissolution, or similar relief under any present or future Federal, State or other statute, law or regulation and shall remain undismissed or unstayed for an aggregate of ninety (90) days (whether or not consecutive), or if any debtor in
possession (whether or not Tenant) trustee, receiver or liquidator of Tenant or of all or any substantial part of its properties or of the Premises shall be appointed without the consent or acquiescence of Tenant and such appointment shall remain
unvacated or unstayed for an aggregate of ninety (90) days (whether or not consecutive) then, and in any of said cases (notwithstanding any license of a former breach of covenant or waiver of the benefit hereof or consent in a former instance).

 Landlord lawfully may, immediately or at any time thereafter, and without demand or further notice terminate
this Lease by notice to Tenant, specifying a date not less than ten (10) days after the giving of such notice on which this Lease shall terminate, and this Lease shall come to an end on the date specified therein as fully and completely as if
such date were the date herein originally fixed for the expiration of the Lease Term (Tenant hereby waiving any rights of redemption), and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter
provided. 
  

	 	(b)	If this Lease shall have been terminated as provided in this Article, then Landlord may, without notice, re- enter the Premises, either by force, summary proceedings,
ejectment or otherwise, and remove and dispossess Tenant and all other persons and any and all property from the same, as if this Lease had not been made, and Tenant hereby waives the service of notice of intention to re-enter or to institute legal
proceedings to that end. 

  

	 	(c)	In the event that this Lease is terminated under any of the provisions contained in Section 7.1 (a) or shall be otherwise terminated by breach of any
obligation 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 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
Term, and 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 deduction of all 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, 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 

  
 37 

 
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, amounts received by Landlord from such reletting for any period shall be credited
only against obligations of Tenant allocable to such period, and shall not be credited against obligations of Tenant hereunder accruing subsequent or prior to such period; nor shall any credit of any kind be due 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 same in the event this Lease is terminated based upon an Event of Default by Tenant hereunder. The marketing of the Premises in a manner similar to the manner in which Landlord markets other premises within
Landlord’s control within the Building shall be deemed to have satisfied Landlord’s obligation to use “reasonable efforts” hereunder. In no event shall Landlord be required to (i) solicit or entertain negotiations with any
other prospective tenant for the Premises until Landlord obtains full and complete possession of the Premises (including, without limitation, the final and unappealable legal right to relet the Premises free of any claim of Tenant), (ii) relet
the Premises before leasing other vacant space in the Building, or (iii) lease the Premises for a rental less than the current fair market rent then prevailing for similar office space in the Building. 

 

	 	(d)	(i) 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 such
termination and whether or not Landlord shall have collected any damages as aforesaid, as liquidated final damages and in lieu of all other 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 for 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 the giving
of such notice represents the amount of the excess, if any, of the total rent and other benefits which would have accrued to Landlord under this Lease from the date of such notice for what would be the then unexpired Lease Term if the Lease terms
had been fully complied with by Tenant over and above the then cash rental value (in advance) of the Premises for the balance of the Lease Term. 

 (ii) For the purposes of this Article, if Landlord elects to require Tenant to pay damages in accordance with the immediately preceding paragraph, the total rent shall be computed by assuming that
Tenant’s share of excess taxes, Tenant’s share of excess operating costs and Tenant’s share of excess electrical costs would be, for the balance of the unexpired Term from the date of such notice, the amount thereof (if any) for the
immediately preceding annual period payable by Tenant to Landlord. 

  
 38 

	 	(e)	In case of any Event of Default, re-entry, dispossession by summary proceedings or otherwise, Landlord may (i) re-let the Premises or any part or parts thereof,
either in the name of Landlord or otherwise, for a term or terms which may at Landlord’s option be equal to or less than or exceed the period which would otherwise have constituted the balance of the Term of this Lease and may grant concessions
or free rent to the extent that Landlord considers advisable or necessary to re-let the same and (ii) may make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary for the
purpose of re-letting the Premises; and the making of such alterations, repairs and decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Landlord shall in no event be liable in any way whatsoever for
failure to re-let the Premises, or, in the event that the Premises are re-let, for failure to collect the rent under re-letting. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the
event of Tenant being evicted or dispossessed, or in the event of Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease. 

 

	 	(f)	The specified remedies to which Landlord may resort hereunder are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be
entitled lawfully, and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were not herein provided for. Further, nothing contained in this Lease shall limit or prejudice
the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the
proceedings in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. In no event shall Tenant ever be liable to Landlord for any indirect or
consequential damages, provided that the foregoing shall not limit or alter any procedural right or remedy of Landlord under this Lease nor shall the same apply to the obligations of Tenant with respect to any hold over by Tenant after the
expiration or earlier termination of this Lease. 

  

	 	(g)	In lieu of any other damages or indemnity and in lieu of the recovery by Landlord of all sums payable under all the foregoing provisions of this Section 7.1,
Landlord may elect to collect from Tenant, by notice to Tenant, at any time after this Lease is terminated under any of the provisions contained in this Article VII or otherwise terminated by breach of any obligation of Tenant and before full
recovery under such foregoing provisions, and Tenant shall thereupon pay, as liquidated damages, an amount equal to the sum of the Annual Fixed Rent and all Additional Rent payable for the twelve (12) months ended next prior to such termination
plus the amount of Annual Fixed Rent and Additional Rent of any kind accrued and unpaid at the time of such election plus any and all expenses which the Landlord may have incurred for and with respect of the collection of any of such rent.

  
 39 

	7.2	Landlord’s Default 

Landlord shall in no event be in de-fault 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. The Tenant shall not assert any right to deduct the cost of repairs or any monetary claim against the Landlord from rent thereafter due and payable, but shall look solely to the Landlord for satisfaction of such claim.

 ARTICLE VIII 
 Insurance and Indemnity 
  

	8.1	Tenant’s Indemnity 

  

	 	(a)	Indemnity. To the fullest extent permitted by law, Tenant waives any right to contribution against the Landlord Parties (as hereinafter defined) and agrees to
indemnify and save harmless the Landlord Parties from and against all claims of whatever nature by a third party arising from or claimed to have arisen from (i) any act, omission or negligence of the Tenant Parties (as hereinafter defined);
(ii) any accident, injury or damage whatsoever caused to any person, or to the property of any person, occurring in or about the Premises from the earlier of (A) the date on which any Tenant Party first enters the Premises for any reason
or (B) the Commencement Date, and thereafter throughout and until the end of the Lease Term, and after the end of the Lease Term for so long after the end of the Lease Term as Tenant or anyone acting by, through or under Tenant is in occupancy
of the Premises or any portion thereof; (iii) any accident, injury or damage whatsoever occurring outside the Premises but within the Building or on common areas or the Complex, where such accident, injury or damage results, or is claimed to
have resulted, from any act, omission or negligence on the part of any of the Tenant Parties; or (iv) any breach of this Lease by Tenant. Tenant shall pay such indemnified amounts as they are incurred by the Landlord Parties. This
indemnification shall not be construed to deny or reduce any other rights or obligations of indemnity that any of the Landlord Parties may have under this Lease or the common law. Notwithstanding anything contained herein to the contrary, Tenant
shall not be obligated to indemnify a Landlord Party for any claims to the extent that such Landlord Party’s damages in fact result from such Landlord Party’s negligence or willful misconduct. 

 

	 	(b)	Breach. In the event that Tenant breaches any of its indemnity obligations hereunder or under any other contractual or common law indemnity: (i) Tenant
shall pay to the Landlord Parties all liabilities, loss, cost, or expense (including attorney’s fees) incurred as a result of said breach; and (ii) the Landlord Parties may deduct and offset from any amounts due to Tenant under this Lease
any amounts owed by Tenant pursuant to this Section 8.1(b). 

  

	 	(c)	 No limitation. The indemnification obligations under this Section 8.1 shall not be limited in any way by any limitation on the amount or
type of damages, compensation or benefits payable by or for Tenant or any subtenant or other occupant of the Premises under 

  
 40 

	 	
workers’ compensation acts, disability benefit acts, or other employee benefit acts. Tenant waives any immunity from or limitation on its indemnity or contribution liability to the Landlord
Parties based upon such acts. 

  

	 	(d)	Subtenants and other occupants. Tenant shall require its subtenants and other occupants of the Premises to provide similar indemnities to the Landlord Parties in
a form acceptable to Landlord. 

  

	 	(e)	Survival. The terms of this Section 8.1 shall survive any termination or expiration of this Lease. 

 

	 	(f)	Costs. The foregoing indemnity and hold harmless agreement shall include indemnity for all costs, expenses and liabilities (including, without limitation,
attorneys’ fees and disbursements) incurred by the Landlord Parties in connection with any such claim or any action or proceeding brought thereon, and the defense thereof. In addition, in the event that any action or proceeding shall be brought
against one or more Landlord Parties by reason of any such claim, Tenant, upon request from the Landlord Party, shall resist and defend such action or proceeding on behalf of the Landlord Party by counsel appointed by Tenant’s insurer (if such
claim is covered by insurance without reservation) or otherwise by counsel reasonably satisfactory to the Landlord Party. The Landlord Parties shall not be bound by any compromise or settlement of any such claim, action or proceeding without the
prior written consent of such Landlord Parties. 

  

	 	8.1.1	Landlord’s Indemnity. Subject to the limitations in Section 9.3 and in Section 8.2 and Section 8.13 of this Article, and to the extent not
resulting from any act, omission, fault, negligence or misconduct of Tenant or its contractors, licensees, invitees, agents, servants or employees, Landlord agrees to indemnify and save harmless Tenant from and against any claim by a third party
arising from any injury to any person occurring in the Premises or in the Complex after the date that possession of the Premises is first delivered to Tenant and until the expiration or earlier termination of the Lease Term, to the extent such
injury results from the gross negligence or willful misconduct of Landlord or Landlord’s employees, or from any breach or default by Landlord in the performance or observance of its covenants or obligations under this Lease; provided, however,
that in no event shall the aforesaid indemnity render Landlord responsible or liable for any loss or damage to fixtures, personal property or other property of Tenant, and Landlord shall in no event be liable for any indirect or consequential
damages. Tenant shall provide notice of any such third party claim to Landlord as soon as practicable. Landlord shall have the right, but not the duty, to defend the claim. The provisions of this Section shall not be applicable to (i) the
holder of any mortgage now or hereafter on the Property or Building (whether or not such holder shall be a mortgagee in possession of or shall have exercised any rights under a conditional, collateral or other assignment of leases and/or rents
respecting the Property or Building), or (ii) any person acquiring title as a result of, or subsequent to, a foreclosure of any such mortgage or a deed in lieu of foreclosure, except to the extent of liability insurance maintained by either of
the foregoing. 

  
 41 

	8.2	Tenant’s Risk 

Tenant agrees to use and occupy the Premises, and to use such other portions of the Building and the Complex as Tenant is given the right
to use by this Lease at Tenant’s own risk. The Landlord Parties shall not be liable to the Tenant Parties for any damage, injury, loss, compensation, or claim (including, but not limited to, claims for the interruption of or loss to a Tenant
Party’s business) based on, arising out of or resulting from any cause whatsoever, including, but not limited to, repairs to any portion of the Premises or the Building or the Complex, any fire, robbery, theft, mysterious disappearance, or any
other crime or casualty, the actions of any other tenants of the Building or of any other person or persons, or any leakage in any part or portion of the Premises or the Building or the Complex, or from water, rain or snow that may leak into, or
flow from any part of the Premises or the Building or the Complex, or from drains, pipes or plumbing fixtures in the Building or the Complex. Any goods, property or personal effects stored or placed in or about the Premises shall be at the sole risk
of the Tenant Party, and neither the Landlord Parties nor their insurers shall in any manner be held responsible therefor. The Landlord Parties shall not be responsible or liable to a Tenant Party, or to those claiming by, through or under a Tenant
Party, for any loss or damage that may be occasioned by or through the acts or omissions of persons occupying adjoining premises or any part of the premises adjacent to or connecting with the Premises or any part of the Building or otherwise. The
provisions of this section shall be applicable to the fullest extent permitted by law, and until the expiration or earlier termination of the Lease Term, and during such further period as Tenant may use or be in occupancy of any part of the Premises
or of the Building. 
  

	8.3	Tenant’s Commercial General Liability Insurance 

 Tenant agrees to maintain in full force on or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, and thereafter
throughout and until the end of the Lease Term, and after the end of the Lease Term for so long as Tenant or anyone acting by, through or under Tenant is in occupancy of the Premises or any portion thereafter, a policy of commercial general
liability insurance, on an occurrence basis, issued on a form at least as broad as Insurance Services Office (“ISO”) Commercial General Liability Coverage “occurrence” form CG 00 01 10 01 or another Commercial General Liability
“occurrence” form providing equivalent coverage. Such insurance shall include broad form contractual liability coverage, specifically covering but not limited to the indemnification obligations undertaken by Tenant in this Lease to the
extent insurable. The minimum limits of liability of such insurance shall be $3,000,000 per occurrence. In addition, in the event Tenant hosts a function in the Premises, Tenant agrees to obtain, and cause any persons or parties providing services
for such function to obtain, the appropriate insurance coverages as determined by Landlord (including liquor liability coverage, if applicable) and provide Landlord with evidence of the same. 

 

	8.4	Tenant’s Property Insurance 

 Tenant shall maintain at all times during the Term of the Lease, and during such earlier time as Tenant may be performing work in or to the Premises or have property, fixtures, furniture, equipment,
machinery, goods, supplies, wares or merchandise on the Premises, and 

  
 42 

 
containing thereafter so long as Tenant is in occupancy of any part of the Premises, business interruption insurance and insurance against loss or damage covered by the so-called “all
risk” type insurance coverage with respect to Tenant’s property, fixtures, furniture, equipment, machinery, goods, supplies, wares and merchandise, and all alterations, improvements and other modifications made by or on behalf of the
Tenant in the Premises, and other property of Tenant located at the Premises, which are permitted to be removed by Tenant at the expiration or earlier termination of the Lease Term except to the extent paid for by Landlord (collectively
“Tenant’s Property”). The business interruption insurance required by this Section 8.4 shall be in minimum amounts typically carried by prudent tenants engaged in similar operations, but in no event shall be in an amount less
than the Annual Fixed Rent then in effect during any year during the Term, plus any Additional Rent due and payable for the immediately preceding year during the Term. The “all risk” insurance required by this section shall be in an amount
at least equal to the full replacement cost of Tenant’s Property. In addition, during such time as Tenant is performing work in or to the Premises, Tenant, at Tenant’s expense, shall also maintain, or shall cause its contractor(s) to
maintain, builder’s risk insurance for the full insurable value of such work. Landlord and such additional persons or entities as Landlord may reasonably request shall be named as loss payees, as their interests may appear, on the policy or
policies required by this Lease. In the event of loss or damage covered by the “all risk” insurance required by this Lease, the responsibilities for repairing or restoring the loss or damage shall be determined in accordance with
Article VI. To the extent that Landlord is obligated to pay for the repair or restoration of the loss or damage covered by the policy, Landlord shall be paid the proceeds of the “all risk” insurance covering the loss or damage. To the
extent Tenant is obligated to pay for the repair or restoration of the loss or damage, covered by the policy, Tenant shall be paid the proceeds of the “all risk” insurance covering the loss or damage. If both Landlord and Tenant are
obligated to pay for the repair or restoration of the loss or damage covered by the policy, the insurance proceeds shall be paid to each of them in the pro rata proportion of their obligations to repair or restore the loss or damage. If the loss or
damage is not repaired or restored (for example, if the Lease is terminated pursuant to Article VI), the insurance proceeds shall be paid to Landlord and Tenant in the pro rata proportion of their relative contributions to the cost of the leasehold
improvements covered by the policy. 
  

	8.5	Tenant’s Other Insurance 

 Tenant agrees to maintain in full force on or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the Commencement Date, and thereafter
throughout the end of the Term, and after the end of the Term for so long after the end of the Term as Tenant or anyone acting by, through or under Tenant is in occupancy of the Premises or any portion thereafter, (1) comprehensive automobile
liability insurance (covering any automobiles owned or operated by Tenant) issued on a form at least as broad as ISO Business Auto Coverage form CA 00 01 07 97 or other form providing equivalent coverage; (2) worker’s compensation
insurance; and (3) employer’s liability insurance. Such automobile liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each accident. Such worker’s compensation insurance shall carry minimum
limits as defined by the law of the jurisdiction in which the Premises are located (as the same may be amended from time to time). Such employer’s liability insurance shall be in an amount not less than One Million Dollars ($1,000,000) for each
accident, One Million 

  
 43 

 
Dollars ($1,000,000) disease-policy limit, and One Million Dollars ($1,000,000) disease-each employee. 
  

	8.6	Requirements for Tenant’s Insurance 

 All insurance required to be maintained by Tenant pursuant to this Lease shall be maintained with responsible companies that are admitted to do business, and are in good standing in the Commonwealth of
Massachusetts and that 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. All such insurance shall: (1) be acceptable in form and content to Landlord; (2) be primary and noncontributory; and (3) contain an endorsement prohibiting cancellation, failure to renew, reduction of amount of insurance, or
change in coverage without the insurer first giving Landlord thirty (30) days’ prior written notice (by certified or registered mail, return receipt requested, or by fax or email) of such proposed action if Tenant’s insurer will
provide same; otherwise, Tenant shall promptly notify Landlord of any failure to renew, reduction of amount of insurance, or material change in coverage). No such policy shall contain any deductible or self-insured retention greater than $25,000.
Such deductibles and self-insured retentions shall be deemed to be “insurance” for purposes of the waiver in Section 8.13 below. Landlord reserves the right from time to time to require Tenant to obtain higher minimum amounts of
insurance based on such limits as are customarily carried with respect to similar properties in the area in which the Premises are located. The minimum amounts of insurance required by this Lease shall not be reduced by the payment of claims or for
any other reason. In the event Tenant shall fail to obtain or maintain any insurance meeting the requirements of this Article, or to deliver such policies or certificates as required by this Article, Landlord may, at its option, on five
(5) days notice to Tenant, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor. 

 

	8.7	Additional Insureds 

 To
the fullest extent permitted by law, the commercial general liability and auto insurance carried by Tenant pursuant to this Lease, and any additional liability insurance carried by Tenant pursuant to Section 8.3 of this Lease, shall name
Landlord, Landlord’s managing agent, and such other persons as Landlord may reasonably request from time to time as additional insureds with respect to liability arising out of or related to this Lease or the operations of Tenant (collectively
“Additional Insureds”). Such insurance shall provide primary coverage without contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds. Such insurance
shall also waive any right of subrogation against each Additional Insured. 
  

	8.8	Certificates of Insurance 

On or before the earlier of (i) the date on which any Tenant Party first enters the Premises for any reason or (ii) the
Commencement Date, Tenant shall furnish Landlord with certificates evidencing the insurance coverage required by this Lease, and renewal certificates shall be furnished to Landlord at least annually thereafter, and at least seven (7) days prior
to the 

  
 44 

 
expiration date of each policy for which a certificate was furnished (acceptable forms of such certificates as of the date hereof for liability and property insurance, respectively, are attached
as Exhibit H), however, other forms may be acceptable. Failure by the Tenant to provide the certificates or letters required by this Section 8.8 shall not be deemed to be a waiver of the requirements in this Section 8.8. Upon request by
Landlord, a true and complete copy of any insurance policy required by this Lease shall be delivered to Landlord within ten (10) days following Landlord’s request. 

 

	8.9	Subtenants and Other Occupants 

 Tenant shall require its subtenants and other occupants of the Premises to provide written documentation evidencing the obligation of such subtenant or other occupant to indemnify the Landlord Parties to
the same extent that Tenant is required to indemnify the Landlord Parties pursuant to Section 8.1 above, and to maintain insurance that meets the requirements of this Article, and otherwise to comply with the requirements of this Article.
Tenant shall require all such subtenants and occupants to supply certificates of insurance evidencing that the insurance requirements of this Article have been met and shall forward such certificates to Landlord on or before the earlier of
(i) the date on which the subtenant or other occupant or any of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents,
invitees or representatives first enters the Premises or (ii) the commencement of the sublease. Tenant shall be responsible for identifying and remedying any deficiencies in such certificates or policy provisions. 

 

	8.10	No Violation of Building Policies 

 Tenant shall not commit or permit any violation of the policies of fire, boiler, sprinkler, water damage or other insurance covering the Complex and/or the fixtures, equipment and property therein carried
by Landlord, or do or permit anything to be done, or keep or permit anything to be kept, in the Premises, which in case of any of the foregoing (i) would result in termination of any such policies, (ii) would adversely affect
Landlord’s right of recovery under any of such policies, or (iii) would result in reputable and independent insurance companies refusing to insure the Complex or the property of Landlord in amounts reasonably satisfactory to Landlord.

  

	8.11	Tenant to Pay Premium Increases 

 If, because of anything done, caused or permitted to be done, or omitted by Tenant (or its subtenant or other occupants of the Premises), the rates for liability, fire, boiler, sprinkler, water damage or
`other insurance on the Complex and equipment of Landlord or any other tenant or subtenant in the Building shall be higher than they otherwise would be, Tenant shall reimburse Landlord and/or the other tenants and subtenants in the Building for the
additional insurance premiums thereafter paid by Landlord or by any of the other tenants and subtenants in the Building which shall have been charged because of the aforesaid reasons, such reimbursement to be made from time to time on
Landlord’s demand. 

  
 45 

	8.12	Landlord’s Insurance 

  

	 	(a)	Required insurance. Landlord shall maintain (i) insurance against loss or damage with respect to the Building on an “all risk” type insurance
form, with customary exceptions, subject to such deductibles and self insured retentions as Landlord may determine, in an amount equal to at least the replacement value of the [Building]; (ii) insurance with respect to any improvements,
alterations, and fixtures of Tenant located at the Premises to the extent paid for by Landlord; and (iii) commercial general liability insurance with respect to the Building in an amount not less than $3,000,000 per occurrence, with deductibles
and self insured retentions as determined by Landlord. The cost of such insurance shall be treated as a part of Landlord’s Operating Expenses. Such insurance shall be maintained with an insurance company or companies selected by Landlord.
Payment for losses thereunder shall be made solely to Landlord. 

  

	 	(b)	Optional insurance. Landlord may maintain such additional insurance with respect to the Building and the Complex, including, without limitation, earthquake
insurance, terrorism insurance, flood insurance, and/or rent insurance, as Landlord may in its sole discretion elect. Landlord may also maintain such other insurance as may from time to time be required by the holder of any mortgage on the Building
or the Property. Such insurance shall be maintained with an insurance company or companies selected by Landlord. Payment for losses thereunder shall be made solely to Landlord. The cost of all such additional insurance shall also be part of the
Landlord’s Operating Expenses. 

  

	 	(c)	Blanket and self-insurance. Any or all of Landlord’s insurance may be provided by blanket coverage maintained by Landlord or any affiliate of Landlord under
its insurance program for its portfolio of properties, or by Landlord or any affiliate of Landlord under a program of self-insurance, and in such event Landlord’s Operating Expenses shall include the portion of the reasonable cost of blanket
insurance or self-insurance that is allocated to the Building. 

  

	 	(d)	No obligation. Landlord shall not be obligated to insure, and shall not assume any liability of risk of loss for, Tenant’s Property, including any such
property or work of Tenant’s subtenants or occupants. Landlord will also have no obligation to carry insurance against, nor be responsible for, any loss suffered by Tenant, subtenants or other occupants due to interruption of Tenant’s or
any subtenant’s or occupant’s business. 

  

	8.13	Waiver of Subrogation 

 To
the fullest extent permitted by law, the parties hereto waive and release any and all rights of recovery against the other, and agree not to seek to recover from the other or to make any claim against the other, and in the case of Landlord, against
all “Tenant Parties” (hereinafter defined), and in the case of Tenant, against all “Landlord Parties” (hereinafter defined), for any loss or damage incurred by the waiving/releasing party to the extent such loss or damage is
insured under any insurance policy required by this Lease or which would have been so insured had the party carried the insurance it was required to carry hereunder, provided that this waiver and release shall not apply to the commercial general
liability insurance Landlord is required to carry by Section 8.12(a)(iii). Tenant shall obtain from its subtenants and other 

  
 46 

 
occupants of the Premises a similar waiver and release of claims against any or all of Tenant or Landlord. In addition, the parties hereto (and in the case of Tenant, its subtenants and other
occupants of the Premises) shall procure an appropriate clause in, or endorsement on, any insurance policy required by this Lease pursuant to which the insurance company waives subrogation. The insurance policies required by this Lease shall contain
no provision that would invalidate or restrict the parties’ waiver and release of the rights of recovery in this section. The parties hereto covenant that no insurer shall hold any right of subrogation against the parties hereto by virtue of
such insurance policy. 
 The term “Landlord Party” or “Landlord Parties” shall mean Landlord, any affiliate
of Landlord, Landlord’s managing agents for the Building, each mortgagee (if any), each ground lessor (if any), and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries,
servants, employees, principals, contractors, licensees, agents or representatives. For the purposes of this Lease, the term “Tenant Party” or “Tenant Parties” shall mean Tenant, any affiliate of Tenant, any permitted subtenant
or any other permitted occupant of the Premises, and each of their respective direct or indirect partners, officers, shareholders, directors, members, trustees, beneficiaries, servants, employees, principals, contractors, licensees, agents, invitees
or representatives. 
  

	8.14	Tenant’s Work 

During such times as Tenant is performing work or having work or services performed in or to the Premises, Tenant shall require its
contractors, and their subcontractors of all tiers, to obtain and maintain commercial general liability, automobile, workers compensation, employer’s liability, builder’s risk, and equipment/property insurance in such amounts and on such
terms as are customarily required of such contractors and subcontractors on similar projects. The amounts and terms of all such insurance are subject to Landlord’s written approval, which approval shall not be unreasonably withheld. The
commercial general liability and auto insurance carried by Tenant’s contractors and their subcontractors of all tiers pursuant to this section shall name Landlord, Landlord’s managing agent, and such other persons as Landlord may
reasonably request from time to time as additional insureds with respect to liability arising out of or related to their work or services (collectively “Additional Insureds”). Such insurance shall provide primary coverage without
contribution from any other insurance carried by or for the benefit of Landlord, Landlord’s managing agent, or other Additional Insureds. Such insurance shall also waive any right of subrogation against each Additional Insured. Tenant shall
obtain and submit to Landlord, prior to the earlier of (i) the entry onto the Premises by such contractors or subcontractors or (ii) commencement of the work or services, certificates of insurance evidencing compliance with the
requirements of this section.

 ARTICLE IX 
 Miscellaneous Provisions 
  

	9.1	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 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. 

 

	9.2	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 to which such party may be lawfully entitled in case of any breach or threatened breach by Tenant 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 a decree compelling specific
performance of any such covenants, conditions or provisions. 
  

	9.3	Quiet Enjoyment 

 This
Lease is subject and subordinate to all matters of record. Tenant, subject to the terms and provisions of this Lease on payment of the rent and observing, keeping and performing all of the terms and provisions of this Lease on Tenant’s part to
be observed, kept and performed, shall lawfully, peaceably and quietly have, hold, occupy and enjoy the Premises during the Term (exclusive of any period during which Tenant is holding over after the termination or expiration of this Lease without
the consent of Landlord), without hindrance or ejection by any persons lawfully claiming under Landlord to have title to the Premises superior to Tenant, subject, however, to the terms of this Lease; the foregoing covenant of quiet enjoyment is in
lieu of any other covenant, express or implied; and it is understood and agreed that this covenant and any and all other covenants of Landlord contained in this Lease shall be binding upon Landlord and Landlord’s successors, including ground or
master 

  
 48 

 
lessees, only with respect to breaches occurring during Landlord’s or Landlord’s successors’ respective ownership of Landlord’s interest hereunder, as the case may be.

 Further, Tenant specifically agrees to look solely to Landlord’s then equity interest in the Building at the time owned,
or in which Landlord holds an interest as ground lessee, for recovery of any judgment from Landlord; it being specifically agreed that neither Landlord (original or successor), nor any beneficiary of any trust of which any person holding
Landlord’s interest is trustee, nor any member, manager, partner, director or stockholder, nor Landlord’s managing agent, shall ever be personally liable for any such judgment, or for the payment of any monetary obligation to Tenant. The
provision contained in the foregoing sentence is not intended to, and shall not, limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or Landlord’s successors in interest, or any action not involving the
personal liability of Landlord (original or successor), any successor trustee to the persons named herein as Landlord, or any beneficiary of any trust of which any person holding Landlord’s interest is 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 equity interest aforesaid in the Building, 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 ever be liable to Tenant
for any indirect or consequential damages or loss of profits or the like. In the event that Landlord shall be determined to have acted unreasonably in withholding any consent or approval under this Lease, the sole recourse and remedy of 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 Tenant under this Lease or act as any termination of this Lease. 
  

	9.4	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 demised 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, and the curing of any of
Landlord’s defaults by such holder or ground lessor within a reasonable time thereafter (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 9.4 or Section 9.14, the term “mortgage” includes a mortgage on a leasehold interest of Landlord (but not one on Tenant’s leasehold interest). 

  
 49 

	9.5	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, shall, by notice sent to Tenant, specifically otherwise elect; and 

 

	 	(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 and 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. 

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 such purchaser-lessor, 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 subject to the provisions of Section 9.3 hereof. In any such event, this Lease shall be subject and subordinate to the lease
to such purchaser provided that such purchaser agrees 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 and provided that Tenant agrees to attorn to such purchaser. 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. 
  

	9.6	Surrender 

 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 prior to the termination of this Lease. The delivery of keys to any employee of Landlord or of Landlord’s agents shall not operate as a termination of the Lease or a surrender of
the Premises. 
  

	9.7	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, if any, designated in Section 1.1 hereof; and in the event any claim is made against the
Landlord 

  
 50 

 
relative to dealings by Tenant with brokers other than the Brokers, if any, designated in Section 1.1 hereof, Tenant shall defend the claim against Landlord with counsel of Tenant’s
selection first approved by Landlord (which approval will not be unreasonably withheld) 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 broker in connection with the consummation of this Lease other
than the broker, person or firm, if any, designated in Section 1.1 hereof; and in the event any claim is made against the Tenant relative to dealings by Landlord with brokers other than the Brokers, if any, designated in Section 1.1
hereof, Landlord shall defend the claim against Tenant with counsel of Landlord’s selection and save harmless and indemnify Tenant on account of loss, cost or damage which may arise by reason of such claim. Landlord agrees that it shall be
solely responsible for the payment of brokerage commissions to the Broker for the Original Term of this Lease, if any, designated in Section 1.1 hereof. 
  

	9.8	Invalidity of Particular Provisions 

 If any term or provision of this Lease, including but not limited to any waiver of contribution or claims, indemnity, obligation, or limitation of liability or of damages, 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. 
  

	9.9	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 subletting or assignment by Tenant. 

 

	9.10	Recording; Confidentiality 

Tenant agrees 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 both Landlord’s and Tenant’s attorneys. In no event shall such document set forth 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.

  
 51 

 
Tenant agrees that this Lease and the terms contained herein will be treated as strictly confidential and except as required by law (or except with the written consent of the Landlord) Tenant
shall not disclose the same to any third party except for Tenant’s partners, lenders, accountants and attorneys who have been advised of the confidentiality provisions contained herein and agree to be bound by the same. In the event Tenant is
required by law to provide this Lease or disclose any of its terms, Tenant shall give Landlord prompt notice of such requirement prior to making disclosure so that Landlord may seek an appropriate protective order. If failing the entry of a
protective order Tenant is compelled to make disclosure, Tenant shall only disclose portions of the Lease which Tenant is required to disclose and will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded to
the information so disclosed. 
  

	9.11	Notices 

 Whenever, by the
terms of this Lease, notice shall or may be given either to Landlord or to Tenant, such notice shall be in writing and shall be sent by overnight commercial courier or by registered or certified mail, postage or delivery charges prepaid, as the case
may be: 
 If intended for Landlord, addressed to Landlord at the address set forth in Article I 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 Landlord, Attention: Regional General Counsel. 
 If intended for Tenant, addressed to Tenant at the address set forth in Article I 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) with a copy to Cooley, LLP 1114 Avenue of the Americas, New York, New York 10036, Attention: Daniel Goldberger, Esq. 

Except as otherwise provided herein, all such notices shall be effective when received; provided, that (i) if receipt is refused,
notice shall be effective upon the first occasion that such receipt is refused, (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 upon the date such delivery was
attempted, (iii) if the notice address is a post office box number, notice shall be effective the day after such notice is sent as provided hereinabove or (iv) if the notice is to a foreign address, notice shall be effective two
(2) days after such notice is sent as provided hereinabove. 
 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 Landlord or by Landlord’s managing agent shall be considered as given by Landlord and shall be fully effective.

  
 52 

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

 

	9.12	When Lease Becomes Binding and Authority 

 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. Landlord and Tenant hereby represents and warrants to the other that all necessary action has been taken to enter this Lease and that the person signing this Lease on behalf of Landlord and
Tenant has been duly authorized to do so. 
  

	9.13	Section Headings 

 The
titles of the Articles throughout this Lease 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. 
  

	9.14	Rights of Mortgagee 

 This
Lease shall be subject and subordinate to any mortgage now or hereafter on the Site or the Building, or both, and to each advance made or hereafter to be made under any mortgage, and to all renewals, modifications, consolidations, replacements and
extensions thereof and all substitutions therefor provided that the holder of such mortgage agrees to recognize the rights of Tenant under this Lease (including the right 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. In confirmation of such subordination and recognition, Tenant shall execute and deliver promptly such instruments of subordination and
recognition as such mortgagee may reasonably request subject to receipt of such instruments of recognition from such mortgagee as Tenant may reasonably request (Tenant hereby agreeing to pay any legal or other fees charged by the mortgagee in
connection with providing the same). Tenant hereby appoints such mortgagee (from time to time) as Tenant’s attorney-in-fact to execute such subordination upon default of Tenant in complying with such mortgagee’s (from time to time)
request. 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 

  
 53 

 
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. 
 If in connection with obtaining financing a bank, insurance company, pension trust or other institutional lender shall request reasonable modifications in this Lease as a condition to such financing,
Tenant will not unreasonably withhold, delay or condition its consent thereto, provided that such modifications do not increase the monetary obligations of Tenant hereunder or materially adversely affect the leasehold interest hereby created.
Landlord represents and warrants that as of the date of this Lease there is no mortgage on the Site or the Building. 
  

	9.15	Status Reports and Financial Statements 

 Recognizing that each party 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, each party, on the request of the other made from time to time, will promptly furnish to the requesting party, or any existing or potential holder of any mortgage encumbering the Premises, the Building, the Site and/or the
Complex or any potential purchaser of the Premises, the Building, the Site and/or the Complex, (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. In addition, Tenant shall deliver to Landlord, or any Interested Party designated by Landlord, financial statements of Tenant and any
guarantor of Tenant’s obligations under this Lease, as reasonably requested by Landlord (but not more frequently that once during any calendar year), including, but not limited to financial statements for the past three (3) years. Landlord
shall keep any non-public information provided by Tenant pursuant to this Section 9.15 confidential, and shall not disclose the same other than (i) to Landlord’s officers, employees and consultants (or to any of the Interested
Parties) or (ii) to the extent required by applicable law or by any administrative, governmental or judicial proceeding. Any such status statement or financial statement delivered by Tenant pursuant to this Section 9.15 may be relied upon
by any Interested Party. 
  

	9.16	Self-Help 

 At any time
after the occurrence of an Event of Default, Landlord shall have the right, but shall not be obligated, to enter upon the Premises and to perform such obligation notwithstanding the fact that no specific provision for such substituted performance by
Landlord is made in this Lease with respect to such default. In performing such obligation, Landlord may make any payment of money or perform any other act. All sums so paid by Landlord (together with interest at the rate of two and one-half
percentage points over the then prevailing prime rate in Boston as set by Bank of America, N.A., or its successor (but in no event greater than the maximum rate permitted by applicable law) and all costs and expenses in connection with the
performance of any such act by Landlord, shall be deemed to be Additional Rent under this Lease and shall be payable to Landlord immediately on 

  
 54 

 
demand. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing Tenant from any of its obligations under this Lease. 

 

	9.17	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) for the first thirty (30) days in which the Tenant holds over an amount equal to one hundred and fifty percent (150%) of the Annual Fixed Rent and Additional Rent calculated (on a daily
basis) at the highest rate payable under the terms of this Lease and after the first thirty days in which the Tenant holds over and thereafter an amount equal to two hundred percent (200%) of the Annual Fixed Rent and 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. In addition, 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; provided, however that Tenant shall not be liable for consequential damages in connection with such holding over
unless such holding over exceeds thirty (30) days from the expiration or earlier 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.

  

	9.18	Extension Option 

 (A) On
the conditions (which conditions Landlord may waive by written notice to Tenant) that both at the time of exercise of the option to extend and as of the commencement of the Extended Term in question (i) there exists no Event of Default (defined
in Section 7.1), (ii) this Lease is still in full force and effect, and (iii) Tenant has neither assigned this Lease nor sublet more than twenty-five percent (25%) of the Premises (except for an assignment or subletting permitted
without Landlord’s consent under Section 5.6.4 hereof), Tenant shall have the right to extend the Term hereof upon all the same terms, conditions, covenants and agreements herein contained (except for the Annual Fixed Rent which shall be
adjusted during the option periods as hereinbelow set forth) for one (1) period of three (3) years as hereinafter set forth. Each option period is sometimes herein referred to as an “Extended Term.” Notwithstanding any
implication to the contrary Landlord has no obligation to make 

  
 55 

 
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 the option to extend the Term, then Tenant shall give notice to Landlord, not earlier than fifteen
(15) months nor later than nine (9) months prior to the expiration of the Term of this Lease exercising such option to extend. Promptly after Landlord’s receipt of the Exercise Notice, Landlord shall provide Landlord’s quotation
to Tenant of a proposed Annual Fixed Rent 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 the Extended Term and executed a written instrument extending the Term of this Lease pursuant to 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 broker determination (the “Broker Determination”) of the Prevailing Market Rent (as defined in Exhibit I) for the
Extended Term, which Broker Determination shall be made in the manner set forth in Exhibit I. If Tenant timely shall have requested the Broker Determination, then the Annual Fixed Rent for the Extended Term shall be the Prevailing Market Rent as
determined by the Broker Determination. If Tenant does not timely request the Broker Determination, then the Annual Fixed Rent during the Extended Term shall be equal to the Landlord’s Rent Quotation. 

(C) Upon the giving of the Exercise Notice by Tenant to Landlord exercising Tenant’s option to extend the Lease Term in accordance
with the provisions of Section 9.18(B) above, then this Lease and the Lease Term hereof shall automatically be deemed extended, for the 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 Extended Term as determined in the relevant manner set forth in this Section 9.18; 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. Notwithstanding anything herein contained
to the contrary, in no event shall the Lease Term hereof be extended for more than three (3) years after the expiration of the Original Term hereof. 
  

	9.19	Security Deposit 

 If, in
Section 1.1 hereof, a security deposit is specified, Tenant agrees that the same will be paid upon execution and delivery of this Lease, and that Landlord shall hold the same, throughout the term of this Lease (including any extension thereof),
as security for the performance by Tenant of all obligations on the part of Tenant to be kept and performed. Landlord shall have the right from time to time without prejudice to any other remedy. Landlord may have on account thereof, to apply such
deposit, or any part thereof, to Landlord’s damages arising from any default on the part of Tenant. If Landlord so applies all or any portion of such deposit, Tenant shall within seven (7) days after notice from Landlord deliver cash to
Landlord in an amount sufficient to restore such deposit to the full amount stated in Section 1.1. While Landlord holds such deposit, Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the same
with Landlord’s 

  
 56 

 
other funds. If Landlord conveys Landlord’s interest under this Lease, the deposit, or any part thereof not previously applied, may be turned over by Landlord to Landlord’s grantee,
and, if so turned over, Tenant agrees to look solely to such grantee for proper application of the deposit in accordance with the terms of this Section 9.19, and the return thereof in accordance herewith. 

Neither the holder of any mortgage nor the lessor in any 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 lessor. 

Initially, Tenant shall have the option to satisfy the security deposit obligation contained in the foregoing paragraphs by delivering to
Landlord a cash security deposit in the amount specified in Section 1.1 concurrently with Tenant’s execution of this Lease (the “Cash Security Deposit”); provided however, that Tenant shall have the obligation to deliver an
irrevocable, unconditional, negotiable letter of credit (the “Letter of Credit”) within sixty (60) days from the date of this Lease, and within thirty (30) days of receipt of the Letter of Credit, Landlord shall return the Cash
Security Deposit to Tenant. Landlord shall have the right to deem any failure by Tenant to deliver the Letter of Credit within the time period required above an Event of Default hereunder. The Letter of Credit shall (i) be issued by and drawn
on a bank reasonably approved by Landlord and at a minimum having a long term issuer credit rating from Standard and Poor’s Professional Rating Service of A or a comparable rating from Moody’s Professional Rating Service, (ii) be
substantially in the form attached hereto as Exhibit G, (iii) permit one or more draws thereunder to be made accompanied only by certification by Landlord or Landlord’s managing agent that pursuant to the terms of this Lease, Landlord is
entitled to draw upon such Letter of Credit, (iv) permit transfers at any time without charge, (v) permit presentment in Boston, Massachusetts (or if the same does not permit presentment in Boston, then such Letter of Credit must provide
for presentment by facsimile) and (vi) provide that any notices to Landlord be sent to the notice address provided for Landlord in this Lease. If the credit rating for the issuer of such Letter of Credit falls below the standard set forth in
(i) above or if the financial condition of such issuer changes in any other material adverse way or if any trustee, receiver or liquidator shall be appointed for the issuer, Landlord shall have the right to require that Tenant provide a
substitute letter of credit that complies in all respects with the requirements of this Section, and Tenant’s failure to provide the same within thirty (30) days following Landlord’s written demand therefor shall entitle Landlord to
immediately draw upon the Letter of Credit. Any such Letter of Credit shall be for a 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). Any failure or refusal of the issuer to honor the Letter of Credit shall be at Tenant’s sole risk and shall not relieve Tenant of its obligations hereunder with regard to the security
deposit. Upon the occurrence of a 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 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 with Landlord in an amount 

  
 57 

 
sufficient to restore such deposit to the full amount stated in this Section 9.19. 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. 

Landlord shall return a Twenty-Four Thousand Dollar ($24,000) portion of such deposit to Tenant so that the remainder of such deposit
shall be Seventy-Four Thousand Dollars ($74,000) (or if such deposit is in the form of a Letter of Credit, Landlord shall exchange the Letter of Credit for a Letter of Credit delivered by Tenant which reduces the amount secured by the Letter of
Credit by the amount stated hereinabove and otherwise in strict conformity with the requirements herein) on the first day of the nineteenth (19th) month of the Lease Term if (i) Tenant is not then in default under the terms of this Lease
without the benefit of notice or grace, (ii) Landlord has not applied such deposit or any portion thereof to Landlord’s damages arising from any default on the part of Tenant, whether or not Tenant has restored the amount so applied by
Landlord and (iii) there have been no more than two (2) Event of Default occurrences during the Term. 
 Landlord shall
return an additional Twenty-Four Thousand Dollar ($24,000) portion of such deposit to Tenant so that the remainder of such deposit shall be Fifty Thousand Dollars ($50,000) (or if such deposit is in the form of a Letter of Credit, Landlord shall
exchange the Letter of Credit for a Letter of Credit delivered by Tenant which reduces the amount secured by the Letter of Credit by the amount stated hereinabove and otherwise in strict conformity with the requirements herein) on the first day of
the twenty-ninth (29th) month of the Lease Term if (i) Tenant is not then in default under the terms of this Lease without the benefit of notice or grace, (ii) Landlord has not applied such deposit, or any portion thereof, to
Landlord’s damages arising from any default on the part of Tenant, whether or not Tenant has restored the amount so applied by Landlord and (iii) there have been no more than two (2) Event of Default occurrences during the Term.

 If Tenant believes that it has satisfied all the conditions precedent to a reduction in the amount of the security deposit,
then it shall request such reduction in writing to Landlord, which request shall certify to Landlord that all such conditions have been satisfied. If Landlord determines that all of the aforesaid conditions are met, the security deposit shall be so
reduced in accordance with this Section. No Letter of Credit shall automatically reduce, but any reduction in the amount thereof shall require Landlord’s prior written notice to the issuer of the Letter of Credit of the reduced amount. Promptly
after Landlord’s receipt of Tenant’s request for a reduction as described above, Landlord shall determine whether such a reduction is permitted in accordance with this Section, and if it is, Landlord shall notify the issuer of the Letter
of Credit of the amount to which the Letter of Credit shall be reduced. In no event shall the security deposit be reduced to less than Fifty Thousand Dollars ($50,000) hereunder. 

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 

  
 58 

 
much thereof as shall not have theretofore been applied in accordance with the terms of this Section 9.19, 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. 
  

	9.20	Late Payment 

 If Landlord
shall not have received any payment or installment of Annual Fixed Rent or Additional Rent (the “Outstanding Amount”) on or before the date on which the same first becomes payable under this Lease (the “Due Date”), the amount of
such payment or installment shall incur a late charge equal to the sum of: (a) five percent (5%) of the Outstanding Amount for administration and bookkeeping costs associated with the late payment and (b) interest on the Outstanding
Amount 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 Bank of America, N.A., (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. Landlord agrees to waive the late charge due hereunder for the first late payment by Tenant under this Lease per calendar year, provided that Landlord receives such payment from Tenant within five (5) business
days of the Due Date (provided further that if such payment is not received with the aforesaid five (5) business day period, interest on the Outstanding Amount will accrue as of the original Due Date). 

 

	9.21	Tenant’s Payments 

Each and every payment and expenditure, other than Annual Fixed Rent, shall be deemed to be Additional Rent or 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 ten (10) days after written demand by Landlord, and in the case of the non-payment of
any such 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 ninety (90) 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. Notwithstanding anything in this Lease to the contrary, if Landlord or any affiliate of Landlord has elected to qualify as a real
estate investment trust (“REIT”), any service required or permitted to be performed by Landlord pursuant to this Lease, the charge or cost of which may be treated as impermissible tenant service income under the laws governing a REIT, may
be performed by a taxable REIT subsidiary that is 

  
 59 

 
affiliated with either Landlord or Landlord’s property manager, an independent contractor of Landlord or Landlord’s property manager (the “Service Provider”). If Tenant is
subject to a charge under this Lease for any such service, then, at Landlord’s direction, Tenant will pay such charge either to Landlord for further payment to the Service Provider or directly to the Service Provider, and, in either case,
(i) Landlord will credit such payment against Additional Rent due from Tenant under this Lease for such service, and (ii) such payment to the Service Provider will not relieve Landlord from any obligation under the Lease concerning the
provisions of such service. 
  

	9.22	Waiver of Trial by Jury 

To induce Landlord to enter into this Lease, 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. 
  

	9.23	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.

 EXHIBIT B-1 
 WORK AGREEMENT 
  

	1.1	Substantial Completion 

  

	 	(A)	Plans and Construction Process. 

  

	 	(1)	Landlord’s Work. Landlord shall perform the work shown on the plans and specifications (the “Plans”) listed on Exhibit B-2 attached to the
Lease (“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 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 (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 increase in costs which costs shall include a construction management fee equal to 4% of the Change Proposal (“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 pursuant thereto (“Landlord’s Change Order Response”). Tenant shall have the right to then approve
or withdraw such Change Proposal within five (5) days after receipt of Landlord’s Change Order Response. If Tenant fails to respond to Landlord’s Change Order Response within such five (5) day period, such Change Proposal shall
be deemed withdrawn. If Tenant approves Landlord’s Change Order Response, 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 1.5 of this Work Agreement. 

 

	 	(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

  
 62 

	 	
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 1.1. 

 

	 	(B)	Substantial Completion; Tenant Delay. 

  

	 	(1)	Landlord’s Obligations. Subject to delays due to Tenant Delays (as hereinafter defined) and delays due to Force Majeure, as defined in
Section 6.1 of the Lease, Landlord shall use reasonable speed and diligence to have the Landlord’s Work substantially completed on or before the Estimated 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 the Lease, without further liability to either party, in accordance with the provisions hereinafter specified in Section 1.2 of this Work
Agreement. 

  

	 	(2)	Definition of Substantial Completion. The Premises shall be treated as having been substantially completed (and ready for occupancy for the purposes of
Section 2.4 of the Lease) on the later of: 

  

	 	(a)	The date on which Landlord’s Work, together with common facilities for access and services to the Premises, has been completed (or would have been 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, the reasonable determination of Landlord’s architect as to such date shall be deemed conclusive and binding on both Landlord and Tenant. 

 

	 	(3)	 Incomplete Work. Landlord shall complete as soon as conditions practically permit any incomplete items of Landlord’s Work, and
Tenant 

  
 63 

	 	
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 in portions of the Premises prior to substantial
completion when 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 or Tenant’s share of electricity, Operating Expenses or Landlord’s Tax Expenses) 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. 

  

	 	(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 as a result of a “Tenant Delay” (as defined below) (i.e. and the Commencement Date has therefore occurred), Tenant shall not (except with Landlord’s consent) 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)	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 Work Agreement; 

  

	 	(b)	Tenant’s failure to pay the Tenant Plan Excess Costs in accordance with Section 1.5 hereinbelow; 

 

	 	(c)	Any delay due to items of work for which there is long lead time in obtaining the materials therefor or 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; 

  

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

  
 64 

	 	(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. 

 

	 	(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 in the exercise of its good faith business judgment. 

  

	 	(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. 

 

	 	(c)	Any amounts due from Tenant to Landlord under this Section 1.1(C)(2) shall be due and payable within thirty (30) days of billing therefore (except that
amounts due in connection with Change Orders shall be paid as provided in Section 1.5), and shall be considered to be Additional Rent. Nothing contained in this Section 1.1(C)(2) shall limit or qualify or prejudice any other covenants,
agreements, terms, provisions and conditions contained in the Lease. 

  

	1.2	Outside Completion Date 

(a) If Landlord shall have failed substantially to complete Landlord’s Work in the Premises described in the Plans on or before the
Outside Completion Date as defined in Section 1.1 of the Lease (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 6.1 of the Lease or any act or failure to act of Tenant which interferes with Landlord’s construction of the Premises without limiting Landlord’s other rights on account thereof), Tenant shall have the right to
terminate the Lease by giving notice to Landlord of Tenant’s desire to do so before such completion and within the time period from the Outside Completion Date (as so extended) until the date which is thirty (30) days subsequent to the
Outside Completion Date (as so extended); and, upon the giving of such notice, the term of the 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. Each day of Tenant Delay shall be deemed conclusively to 

  
 65 

 
cause an equivalent day of delay by Landlord in substantially completing Landlord’s Work pursuant to Section 1.1 of this Work Agreement, and thereby automatically extend for each such
equivalent day of delay the date of the Outside Completion Date. 
 (b) If Landlord shall have failed substantially to complete
Landlord’s Work described in the Plans on or before the date which is fifteen (15) days after the Outside Completion Date (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 or any Tenant Delay without limiting Landlord’s other rights on account thereof) and Tenant has not terminated the Lease as provided in Section 1.2(a) hereinabove, the Annual
Fixed Rent and Tenant’s payments on account of Operating Cost Excess and Tax Excess shall be abated by one (1) day for each day beyond the date which is fifteen (15) days subsequent to the Outside Completion Date (as so extended) that
Landlord thus fails to substantially complete the Landlord’s Work described in the Plans, with such abatement to be applied commencing on the Phase I Rent Commencement Date. 

(c) The foregoing rent abatement and right of termination shall be Tenant’s sole and exclusive remedies at law or in equity or
otherwise for Landlord’s failure to substantially complete the Landlord’s Work within the time periods set forth above. 
  

	1.3	Quality and Performance of Work 

 All construction work required or permitted by the Lease shall be clone 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 5.12 of the Lease). 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 1.1 of the Lease 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 Work Agreement (if any) (i) not
later than the end of the sixth (6th) full calendar
month next beginning after the Commencement Date with respect to the heating, ventilating and air conditioning systems servicing the Premises, and (ii) not later than the third (3rd) full calendar month next beginning after the Commencement Date with respect to Landlord’s construction
obligations under this Work Agreement not referenced in (i) above, 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 Work Agreement (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 as to which, in either case, Tenant shall have given notice to
Landlord, as aforesaid. 

  
 66 

	1.4	Intentionally Omitted 

  

	1.5	Tenant Plan Excess Costs 

Notwithstanding anything contained in this Work Agreement 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-2 attached to the Lease and the costs of any items of work shown as a “Tenant Cost” on Exhibit B-2 (by virtue of an “X” being noted in the Tenant Cost column)
(the “Tenant Plan Excess Costs”). To the extent, if any, that there are Tenant Plan Excess Costs, Tenant shall pay Landlord, as Additional Rent, fifty percent (50%) of the Tenant Plan Excess Costs prior to the commencement of the
Landlord’s Work, with the balance of the Tenant Plan Excess Costs due upon substantial completion of the Landlord’s Work; provided, however, that in the event that the Tenant Plan Excess Costs exceed $10,000 (the “Maximum
Amount”), then Tenant shall pay to Landlord, as Additional Rent, at the time that Tenant approves any Change Order that causes the Tenant Plan Excess Costs to exceed the Maximum Amount, all Tenant Plan Excess Costs in excess of the Maximum
Amount, provided, however, that if the Tenant Plan Excess Costs exceed the Maximum Amount as a result of a Change Order, then Tenant shall pay to Landlord, as Additional Rent, at the time Tenant approves such Change Order in accordance with
Section 1.1(A)(2), all such Tenant Plan Excess Costs in excess of the Maximum Amount.

 EXHIBIT I 
 BROKER’S DETERMINATION OF PREVAILING MARKET RATE 
 The following procedures and requirements
shall apply: 
  

	1.	Tenant’s Request. Tenant shall send a notice to Landlord in accordance with the Lease, requesting a Broker Determination of the Prevailing Market Rent,
which notice to be effective must (i) include the name of a broker selected by Tenant to act for Tenant, which broker shall be affiliated with a major Boston commercial real estate brokerage firm selected by Tenant and which broker shall have
at least ten (10) years experience dealing in properties of a nature and type generally similar to the Building located in the Boston West Suburban market, and (ii) explicitly state that Landlord is required to notify Tenant within thirty
(30) days of an additional broker selected by Landlord. 

  

	2.	Landlord’s Response. Within thirty (30) days after Landlord’s receipt of Tenant’s notice requesting the Broker Determination and stating the
name of the broker selected by Tenant, Landlord shall give written notice to Tenant of Landlord’s selection of a broker having at least the affiliation and experience referred to above. 

 

	3.	Selection of Third Broker. Within ten (10) days thereafter the two (2) brokers so selected shall select a third such broker also having at least the
affiliation and experience referred to above. 

  

	4.	Rental Value Determination. Within thirty (30) days after the selection of the third broker, the three (3) brokers so selected, by majority opinion,
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 shall take into account all relevant factors. The brokers shall advise Landlord and Tenant in
writing by the expiration of said thirty (30) day period of the annual fair market rental value. 

  

	5.	Resolution of Broker Deadlock. If the Brokers are unable to agree at least by majority on a determination of annual fair market rental value, then the brokers
shall send a notice to Landlord and Tenant by the end of the thirty (30) day period for making said determination setting forth their individual determinations of annual fair market rental value, and the highest such determination and the
lowest such determination shall be disregarded and the remaining determination shall be deemed to be the determination of annual fair market rental value. 

  

	6.	Costs. Each party shall pay the costs and expenses of the broker selected by it and each shall pay one half (1/2) of the costs and expenses of the third
broker. 

  

	7.	 Failure to Select Broker or Failure of Broker to Serve. If Tenant shall have requested a Broker Determination and Landlord shall not have
designated a broker within the time period provided therefor above and such failure shall continue for more than
 ten (10)

  
 83 

	 	
days after notice thereof, then Tenant’s broker shall alone make the determination of the fair market rent of value in writing to Landlord and Tenant within thirty (30) days after the
expiration of Landlord’s right to designate a broker hereunder. If Tenant and Landlord have both designated brokers but the two brokers so designated do not, within a period of fifteen (15) days after the appointment of the second broker,
agree upon and designate the third broker willing so to act, the Tenant, the Landlord or either broker previously designated may request the Boston Bar Association (or such organization as may succeed to the Boston Bar Association), to designate the
third broker willing so to act and a broker so appointed shall, for all purposes, have the same standing and powers as though he had been seasonably appointed by the brokers first appointed. In case of the inability or refusal to serve of any person
designated as a broker, or in case any broker for any reason ceases to be such, a broker to fill such vacancy shall be appointed by the Tenant, the Landlord, the brokers first appointed or the Boston Bar Association 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 broker who continues to act or by the Landlord or Tenant such vacancy may be filled by the Boston Bar Association
and any broker so appointed to fill such vacancy shall have the same standing and powers as though originally appointed
