Term. The term of the leasehold granted by this Lease (as the same may be extended pursuant to Article 42 hereof, and as the same may be earlier terminated in accordance with this Lease, the “Term”) shall commence on
the Term Commencement Date (as defined in Article 4) and end on the date (the “Term Expiration Date”) that is one hundred ten (110) months after the Term Commencement Date, subject to extension or earlier termination of
this Lease as provided herein. 
 4. Possession and Commencement Date. 

4.1 Landlord shall use commercially reasonable efforts to tender possession of the Premises to Tenant on the Estimated Term Commencement Date,
with the work (the “Tenant Improvements”) required of Landlord described in the Work Letter attached hereto as Exhibit B (the “Work Letter”) and the base building laboratory infrastructure work as more specifically
described in Exhibit B-2 attached hereto (the “Landlord’s Work”) each Substantially Complete (as defined below). Tenant agrees that in the event such work is not Substantially Complete on or before the Estimated Term
Commencement Date for any reason, then (a) this Lease shall not be void or voidable, (b) Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, (c) the Term Expiration Date shall be extended accordingly and
(d) Tenant shall not be responsible for the payment of any Base Rent or Tenant’s Adjusted Share of Operating Expenses (as defined below) until the actual Term Commencement Date as described in Section 4.2 occurs. Notwithstanding the
foregoing, in the event Substantial Completion of the Landlord’s Work shall occur subsequent to the date which is ninety (90) days following the Estimated Term Commencement Date, Tenant shall receive a credit against Tenant’s
obligation to pay Base Rent hereunder from and after such date, on a per diem basis, for each day during the period from the ninety-first (91st) day following the Estimated Term Commencement
Date until Landlord has Substantially Completed the Landlord’s Work, provided that such delay has not been caused in any way by a Tenant Delay or Force Majeure. The term “Substantially Complete” or “Substantial
Completion” means, (x) with respect to the Tenant Improvements, that the Tenant Improvements are substantially complete in accordance with the Approved Plans (as defined in the Work Letter), except for punch list items that will not
materially adversely affect Tenant’s occupancy and operations in the Premises, as reasonably determined by Landlord’s architect, (y) the Landlord’s Work (including all base building systems necessary for Tenant’s occupancy
and operations) is substantially complete except for punch list items that will not materially adversely affect Tenant’s occupancy and operations in the Premises, as reasonably determined by Landlord’s architect, and (z) the Premises
may be legally occupied pursuant to a temporary certificate of occupancy or its substantial equivalent (such as sign-off on the building permit by the Governmental Authority that issued such permit), to the extent required by Applicable Laws for
occupancy of the Premises. Tenant shall have the right to review the above-mentioned punch lists. Notwithstanding anything in this Lease (including the Work Letter) to the contrary, Landlord’s obligation to timely achieve Substantial Completion
shall be subject to extension on a day-for-day basis as a result of Force Majeure (as defined below) or Tenant Delay (as defined below). 

  
 5 













 4.2 The “Term Commencement Date” shall be the date Landlord tenders
possession of the Premises to Tenant with the Tenant Improvements and Landlord’s Work Substantially Complete. If possession is delayed by Tenant Delay, then the Term Commencement Date shall be the date that the Term Commencement Date would have
occurred but for such Tenant Delay. Tenant shall execute and deliver to Landlord written acknowledgment of the actual Term Commencement Date and the Term Expiration Date within ten (10) days after Tenant takes possession of the Premises, in the
form attached as Exhibit C hereto. Failure to execute and deliver such acknowledgment, however, shall not affect the Term Commencement Date or Landlord’s or Tenant’s liability hereunder. Failure by Tenant to obtain any governmental
licensing or similar governmental approval of the Premises required for the Permitted Use by Tenant shall not serve to extend the Term Commencement Date. 

As used herein, the term “Tenant Delay” shall mean any actual delay in Landlord’s achievement of Substantial Completion of the Tenant
Improvements or Landlord’s Work, in either case as a result of any of the following: 
 (i) Tenant’s request for
Change Requests; 
 (ii) Any Changes to the Approved TI Construction Documents requested by Tenant and approved by Landlord;

 (iii) Tenant’s request for materials, finishes or installations requiring unusually long lead times for which
Landlord has provided a written estimate of such lead times; 
 (iv) Tenant’s delay in reviewing, revising or approving
plans and specifications beyond the periods set forth herein that is not caused by Landlord’s failure to timely perform its obligations hereunder; 

(v) Tenant’s delay in making payments to Landlord for Excess TI Costs; 

(vi) Tenant’s failure to timely comply with its obligations under the Work Letter and/or the Lease within applicable
notice and cure periods; or 
 (vii) Any other act or omission by Tenant which continues for 2 business days after written
notice from Landlord. 
 4.3 In the event that Landlord permits Tenant to enter upon the Premises prior to the Term Commencement Date for the
purpose of installing improvements or the placement of personal property (which Landlord shall reasonably permit provided such access does not interfere with construction or inspection work being performed on behalf of Landlord and is coordinated
with Landlord’s contractors), Tenant shall furnish to Landlord evidence satisfactory to Landlord in advance that insurance coverages required of Tenant under the provisions of Article 23 are in effect, and such entry shall be subject to
all the terms and conditions of this Lease other than the payment of Base Rent; and provided, further, that if the Term Commencement Date is delayed due to such early access, then the Term Commencement Date shall be the date that the Term
Commencement Date would have occurred but for such Tenant Delay. 

  
 6 













 4.4 Landlord shall cause the Tenant Improvements to be constructed in the Premises pursuant
to the Work Letter at a cost to Landlord not to exceed (a) Six Million Three Hundred Thirty Three Thousand Six Hundred Dollars ($6,333,600.00) (based upon Two Hundred Dollars ($200.00) per square foot of Rentable Area (as defined below and
subject to change based upon the Rentable Area of the Premises as of the Term Commencement Date) (the “Base TI Allowance”) plus (b) if properly requested by Tenant pursuant to this Section, Four Hundred Seventy-Five Thousand
Twenty Dollars ($475,020.00) (based upon Fifteen Dollars ($15.00) per square foot of Rentable Area and subject to change based upon the Rentable Area of the Premises as of the Term Commencement Date) (the “Additional TI Allowance”),
for a total of Six Million Eight Hundred Eight Thousand Six Hundred Twenty Dollars ($6,808,620.00) (based upon Two Hundred Fifteen Dollars ($215.00) per square foot of Rentable Area and subject to change based upon the Rentable Area of the Premises
as of the Term Commencement Date). The Base TI Allowance, together with the Additional TI Allowance (if properly requested by Tenant pursuant to this Article), shall be referred to herein as the “TI Allowance.” The TI Allowance may
be applied to the costs of (m) construction, (n) project management by Landlord (which fee shall equal three percent (3%) of the cost of the Tenant Improvements, including the Base TI Allowance and, if used by Tenant, the Additional
TI Allowance), (o) commissioning of mechanical, electrical and plumbing systems by a licensed, qualified commissioning agent hired by Landlord, and review of such party’s commissioning report by a licensed, qualified commissioning agent
hired by Tenant, (p) space planning, architect, engineering and other related services performed by third parties unaffiliated with Tenant, (q) building permits and other taxes, fees, charges and levies by Governmental Authorities (as
defined below) for permits or for inspections of the Tenant Improvements, and (r) costs and expenses for labor, material, equipment and fixtures. In no event shall the TI Allowance be used for (w) payments to Tenant or any affiliates of
Tenant, (x) the purchase of any furniture, personal property or other non-building system equipment, (y) costs arising from any default by Tenant of its obligations under this Lease or (z) costs that are recoverable by Tenant from a
third party (e.g., insurers, warrantors, or tortfeasors) which may include, by way of example only, damage to the Premises or Building caused by Tenant for which Tenant carries or is required to carry insurance. 

4.5 Landlord shall not have any obligation to fund any unused portion of the TI Allowance after the date that is ten (10) months after the
Term Commencement Date (the “TI Deadline”), after which date Landlord’s obligation to fund any such costs shall expire. Initial Base Rent shall be increased to include the amount of the Additional TI Allowance disbursed by
Landlord upon written request by Tenant in accordance with this Lease amortized over the initial Term at a rate of eight percent (8%) annually for each Dollar of the Additional TI Allowance disbursed by Landlord in accordance with this Lease.
The amount by which Base Rent shall be increased shall be determined (and Base Rent shall be increased accordingly) as of the Term Commencement Date and, if such determination does not reflect use by Tenant of all of the Additional TI Allowance,
shall be determined again as of the TI Deadline, with Tenant paying (on the next succeeding day that Base Rent is due under this Lease (the “TI True-Up Date”)) any underpayment of the further adjusted Base Rent for the period
beginning on the Term Commencement Date and ending on the TI True-Up Date. The initial Base Rent, as adjusted to reflect the disbursement of the Additional TI Allowance in accordance with this Section, shall be subject to further annual adjustments
as set forth in Section 8.1. 

  
 7 













 4.6 Tenant shall pay the costs of the Tenant Improvements on a pari passu basis with
Landlord as such costs are paid, in the proportion of Excess TI Costs payable by Tenant to the Base TI Allowance (and, if properly requested by Tenant pursuant to this Lease, the Additional TI Allowance) payable by Landlord. Landlord shall not be
obligated to expend any portion of the Additional TI Allowance until Landlord shall have received from Tenant a letter in the form attached as Exhibit D hereto executed by an authorized officer of Tenant with respect to each Additional TI
Allowance. In no event shall any unused TI Allowance entitle Tenant to a credit against Rent payable under this Lease. 
 4.7 Notwithstanding
anything to the contrary in this Lease, Landlord and Tenant agreed that all Tenant Improvements shall incorporate flexible wall and lab bench systems. 

4.8 To the extent assignable, Landlord will assign to Tenant all warranties obtained by Landlord in connection with the Tenant Improvements;
provided, however, that notwithstanding any such assignment, Landlord shall also retain the right to enforce such warranties against the applicable contractor, at Landlord’s sole option. Landlord shall use commercially reasonable efforts to
enforce all construction warranties with respect to the Landlord’s Work including without limitation with respect to the base building HVAC, mechanical, electrical and plumbing systems, the roof and elevators. 

4.9 As used herein, “Landlord Delay” means any actual delay in completion of the Tenant Improvements resulting from
(a) Landlord’s failure to respond to any requests from Tenant for approvals required from Landlord under the Work Letter beyond the express time periods set forth under the Work Letter or (b) any matter expressly described in this
Lease and/or the Work Letter as constituting a Landlord Delay, in each case to the extent such act or omission actually delays the completion of the Tenant Improvements beyond the date when the Tenant Improvements would have otherwise occurred and
the same is not caused by Force Majeure or Tenant Delays. Notwithstanding any Landlord Delay, Tenant shall exercise commercially reasonable efforts to mitigate any Landlord Delay. If there is a Landlord Delay, then Tenant shall give Landlord written
notice of such Landlord Delay (which notice will be delivered in accordance with the notice provisions of Section 39 of this Lease, with a copy via e-mail to Landlord’s Authorized Representative in the Work Letter) describing in
reasonable detail the facts and circumstances constituting the alleged delay and the manner in which such facts and circumstances are affecting timely completion of the Tenant Improvements. 

5. Condition of Premises. Tenant acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty with respect to
the condition of the Premises, the Building or the Project, or with respect to the suitability of the Premises, the Building or the Project for the conduct of Tenant’s business. Tenant acknowledges that (a) it is fully familiar with the
condition of the Premises and agrees to take the same in its condition “as is” as of the Term Commencement Date and (b) Landlord shall have no obligation to alter, repair or otherwise prepare the Premises for Tenant’s occupancy
or to pay for or construct any improvements to the Premises, except for performance of the Tenant Improvements and Landlord’s Work, and payment of the Base TI Allowance and, if properly requested by Tenant pursuant to the terms of the Lease,


  
 8 













 
the Additional TI Allowance. Subject to the terms and conditions of this Lease, Tenant’s taking of possession of the Premises shall, except as otherwise agreed to in writing by Landlord and
Tenant, conclusively establish that Landlord’s Work and the Tenant Improvements are Substantially Complete, and the Premises, the Building and the Project were at such time in good, sanitary and satisfactory condition and repair. 

6. Rentable Area. 
 6.1 The term
“Rentable Area” shall reflect such areas as reasonably calculated by Landlord’s architect in a manner consistent with Landlord’s determination of Rentable Area for the remainder of the Building and Project, as the same may
be reasonably adjusted from time to time by Landlord in consultation with Landlord’s architect to reflect changes to the Premises, the Building or the Project, as applicable. Notwithstanding the foregoing to the contrary, in no event shall the
Rentable Area of the Premises, the Building or the Project be deemed to have increased unless due to a change in the outer dimensions of the exterior walls of the same. 

6.2 The Rentable Area of the Building is generally determined by making separate calculations of Rentable Area applicable to each floor within
the Building and totaling the Rentable Area of all floors within the Building. The Rentable Area of a floor is computed by measuring to the outside finished surface of the permanent outer Building walls. The full area calculated as previously set
forth is included as Rentable Area, without deduction for columns and projections or vertical penetrations, including stairs, elevator shafts, flues, pipe shafts, vertical ducts and the like, as well as such items’ enclosing walls. 

6.3 The term “Rentable Area,” when applied to the Premises, is that area equal to the usable area of the Premises, plus an
equitable allocation of Rentable Area within the Building that is not then utilized or expected to be utilized as usable area, including that portion of the Building devoted to corridors, equipment rooms, restrooms, elevator lobby, atrium and
mailroom. 
 6.4 The Rentable Area of the Project is the total Rentable Area of all buildings within the Project. 

6.5 Review of allocations of Rentable Areas as between tenants of the Building and the Project shall be made as frequently as Landlord deems
appropriate, including in order to facilitate an equitable apportionment of Operating Expenses (as defined below). If such review is by a licensed architect and allocations are certified by such licensed architect as being correct, then Tenant shall
be bound by such certifications, but in no event shall the Rentable Area of the Premises or the Building be subject to remeasurement except as otherwise provided in Section 6.1 hereof. 

7. Rent. 
 7.1 Tenant shall pay to Landlord
as Base Rent for the Premises, commencing on the date which is two (2) months following the Term Commencement Date (the “Rent Commencement Date”), the sums set forth in Section 2.3, subject to the rental adjustments
provided in Article 8 hereof. Base Rent shall be paid in equal monthly installments as set forth in Section 2.3, subject to the rental adjustments provided in Article 8 hereof, each in advance on the first day of each and
every calendar month during the Term. 

  
 9 













 7.2 In addition to Base Rent, Tenant shall pay to Landlord as additional rent
(“Additional Rent”) at times hereinafter specified in this Lease (a) Tenant’s Adjusted Share (as defined below) of Operating Expenses (as defined below), (b) the Property Management Fee (as defined below) and
(c) any other amounts that Tenant assumes or agrees to pay under the provisions of this Lease that are owed to Landlord, including any and all other sums that may become due by reason of any default of Tenant or failure on Tenant’s part to
comply with the agreements, terms, covenants and conditions of this Lease to be performed by Tenant, after notice and the lapse of any applicable cure periods. 

7.3 Base Rent and Additional Rent shall together be denominated “Rent.” Rent shall be paid to Landlord, without abatement, deduction
or offset, in lawful money of the United States of America to the address set forth in Section 2.8 or to such other person or at such other place as Landlord may from time designate in writing. In the event the Term commences or ends on
a day other than the first day of a calendar month, then the Rent for such fraction of a month shall be prorated for such period on the basis of the number of days in the month and shall be paid at the then-current rate for such fractional month.

 7.4 Tenant’s obligation to pay Rent shall not be discharged or otherwise affected by (a) any Applicable Laws now or hereafter
applicable to the Premises, (b) any other restriction on Tenant’s use, (c) except as expressly provided herein, any casualty or taking or (d) any other occurrence; and Tenant waives all rights now or hereafter existing to
terminate or cancel this Lease or quit or surrender the Premises or any part thereof, or to assert any defense in the nature of constructive eviction to any action seeking to recover rent. Tenant’s obligation to pay Rent with respect to any
period or obligations arising, existing or pertaining to the period prior to the date of the expiration or earlier termination of the Term or this Lease shall survive any such expiration or earlier termination; provided, however, that
nothing in this sentence shall in any way affect Tenant’s obligations with respect to any other period. 
 8. Rent Adjustments. 

8.1 Base Rent shall be subject to an annual upward adjustment of three percent (3%) of the then-current Base Rent. The first such
adjustment shall become effective commencing on the first (1st) annual anniversary of the Rent Commencement Date, and subsequent adjustments shall become effective on every successive annual
anniversary for so long as the initial Term of this Lease continues in effect. The amount of Base Rent during any extension period shall be governed by Article 42 hereof. 

8.2 Notwithstanding anything to the contrary contained in this Lease, Tenant shall not be required to pay Base Rent for the first two
(2) months of the Term (such period, the “Free Rent Period”); provided, however, that the total amount of Base Rent abated during the Free Rent Period shall not exceed Four Hundred Ninety Thousand Eight Hundred
Fifty-Four Dollars ($490,854.00) (the “Free Rent Cap”). The Free Rent Cap shall not be increased as a result of any increase in Base Rent arising from Landlord’s disbursement of any Additional TI Allowance, and the period for
amortization of the Additional TI Allowance shall commence after the Free Rent Period ends, with payments of increased Base Rent resulting from any Additional TI Allowance commencing upon expiration of the Free Rent Period. During the Free Rent
Period, Tenant shall continue to be responsible for the payment of all of Tenant’s other Rent obligations under this Lease, including 

  
 10 













 
all Additional Rent such as Operating Expenses, the Property Management Fee, and costs of utilities for the Premises. In the event of any Default that results in termination of this Lease, then,
as part of the recovery to which Landlord is entitled pursuant to this Lease, and in addition to any other rights or remedies to which Landlord may be entitled pursuant to this Lease (including Article 31), at law or in equity, Landlord shall
be entitled to the immediate recovery, as of the day immediately prior to such termination of the Lease, of the unamortized amount of Base Rent that Tenant would have paid had the Free Rent Period not been in effect. 

9. Operating Expenses.

herein, the term “Operating Expenses” shall mean: 
 (a) Government impositions, including property tax costs consisting of

 11

office used for Project operations is maintained at the Project, plus customary expenses for such office; Permitted Capital Expenditures (as defined below); costs of complying with Applicable Laws (except to the extent such costs are incurred to
remedy non-compliance as of the Term Commencement Date with Applicable Laws); costs to keep the Project in compliance with, or costs or fees otherwise required under or incurred pursuant to any CC&Rs (as defined below), including condominium

the terms of insurance policies; service contracts; costs of services of independent contractors retained to do work of a nature referenced above; and costs of compensation (including employment taxes and fringe benefits) of all persons who perform

gardeners, sweepers, plow truck drivers, handymen, and engineering/maintenance/facilities personnel. 
 (c) Notwithstanding the foregoing,
Operating Expenses shall not include any net income, franchise, capital stock, estate or inheritance taxes, or taxes that are the personal obligation of Tenant or of another tenant of the Project; any leasing commissions; expenses that relate to
preparation of rental space for a tenant; Landlord’s Work and other expenses of initial development and construction, including grading, paving, landscaping and decorating (as distinguished from maintenance, repair and replacement of the

bond payable in installments shall constitute an Operating Expense under Subsection 9.1(a)); rent paid under a ground lease of the Property; salaries of executive officers of Landlord; depreciation claimed by Landlord for tax purposes (provided that
this exclusion of depreciation is not intended to delete from Operating Expenses actual costs of repairs and replacements that are provided for in Subsection 9.1(b)); taxes that are excluded from Operating Expenses by the last sentence of
Subsection 9.1(a); costs expressly excluded from Operating Expenses elsewhere in this Lease or that are charged to or paid by Tenant under other provisions of this Lease; professional fees and disbursements and other costs and expenses
related to the ownership (as opposed to the use, occupancy, operation, maintenance or repair) of the Project; legal and accounting fees relating to (A) disputes with tenants, prospective tenants or other occupants of the Building,
(B) disputes with purchasers, prospective purchasers, mortgagees or prospective mortgagees of the Building or the Property or any part of either, or (C) negotiations of leases, contracts of sale or mortgages; costs in the nature of
penalties or fines arising from Landlord’s gross negligence or willful misconduct; costs for services, supplies or repairs paid to any Affiliate of Landlord in excess of costs that would be payable in an “arm’s length” or
unrelated situation for comparable services, supplies or repairs; reserves; cost of any work or services performed for any facility other than the Building, Property or Project; cost of initial cleaning and rubbish removal from the Building or the
Property to be performed before final completion of the Building or tenant space; cost of initial landscaping of the Building or the 

  
 12 













 
Property; cost of the initial stock of tools and equipment for operation, repair and maintenance of the Building or the Property; cost of purchasing fine art; costs and expenses of organizing and
maintaining the Landlord entity; and any item that, if included in Operating Expenses, would involve a double collection for such item by Landlord. To the extent that Tenant uses more than Tenant’s Pro Rata Share of any item of Operating
Expenses, Tenant shall pay Landlord for such excess in addition to Tenant’s obligation to pay Tenant’s Pro Rata Share of Operating Expenses (such excess, together with Tenant’s Pro Rata Share, “Tenant’s Adjusted
Share”). 
 (d) As used herein, “Permitted Capital Expenditures” shall mean capital expenditures incurred
(i) in replacing obsolete equipment, as such term is defined on Exhibit J attached hereto, (ii) for the primary purpose of reducing Operating Expenses or (iii) required by any Governmental Authority to comply with changes in
Applicable Laws that take effect after the Execution Date or to ensure continued compliance with Applicable Laws in effect as of the Execution Date, in each case amortized over the useful life thereof, as reasonably determined by Landlord, in
accordance with generally accepted accounting principles. 
 9.2 Commencing on the earlier of (i) the Rent Commencement Date and
(ii) the date Tenant occupies the Premises for the conduct of business, Tenant shall pay to Landlord on the and first day of each calendar month of the Term, as Additional Rent, (a) the Property Management Fee (as defined below) and
(b) Landlord’s estimate of Tenant’s Adjusted Share of Operating Expenses with respect to the Building and the Project, as applicable, for such month. 

(w) The “Property Management Fee” shall equal three percent (3%) of Base Rent due from Tenant. Tenant shall pay the
Property Management Fee in accordance with Section 9.2 with respect to the entire Term, including any extensions of the Term, or any holdover periods, regardless of whether Tenant is obligated to pay Base Rent, Operating Expenses or any
other Rent with respect to any such period or portion thereof. 
 (x) Within ninety (90) days after the conclusion of each calendar year
(or such longer period as may be reasonably required by Landlord), Landlord shall furnish to Tenant a statement showing in reasonable detail the actual Operating Expenses, Tenant’s Adjusted Share of Operating Expenses, and the cost of providing
utilities to the Premises for the previous calendar year (“Landlord’s Statement”). Any additional sum due from Tenant to Landlord shall be due and payable within thirty (30) days after receipt of an invoice therefor. If
the amounts paid by Tenant pursuant to this Section exceed Tenant’s Adjusted Share of Operating Expenses for the previous calendar year, then Landlord shall credit the difference against the Rent next due and owing from Tenant; provided
that, if the Lease term has expired, Landlord shall accompany Landlord’s Statement with payment for the amount of such difference. 

(y) Any amount due under this Section for any period that is less than a full month shall be prorated for such fractional month on the basis of
the number of days in the month. 
 9.3 Landlord or an affiliate(s) of Landlord may own other property(ies) adjacent to the Project or its
neighboring properties (collectively, “Neighboring Properties”). In connection with Landlord performing services for the Project pursuant to this Lease, similar services may be performed by the same vendor(s) for Neighboring
Properties. In such a case, Landlord shall reasonably allocate to each Building and the Project the costs for such services based upon the 

  
 13 













 
ratio that the square footage of the Building or the Project (as applicable) bears to the total square footage of all of the Neighboring Properties or buildings within the Neighboring Properties
for which the services are performed, unless the scope of the services performed for any building or property (including the Building and the Project) is disproportionately more or less than for others, in which case Landlord shall equitably
allocate the costs based on the scope of the services being performed for each building or property (including the Building and the Project). Since the Project consists of multiple buildings, certain Operating Expenses may pertain to a particular
building(s) and other Operating Expenses to the Project as a whole. Landlord reserves the right in its sole discretion to allocate any such costs applicable to any particular building within the Project to such building, and other such costs
applicable to the Project to each building in the Project (including the Building), with the tenants in each building being responsible for paying their respective proportionate shares of their buildings to the extent required under their leases.
Landlord shall allocate such costs to the buildings (including the Building) in a reasonable, non-discriminatory manner, and such allocation shall be binding on Tenant. 

9.4 Landlord’s annual statement shall be final and binding upon Tenant unless Tenant, within ninety (90) days after Tenant’s
receipt thereof, shall contest any item therein by giving written notice to Landlord, specifying each item contested and the reasons therefor; provided that Tenant shall in all events pay the amount specified in Landlord’s annual statement,
pending the results of the Independent Review and determination of the Accountant(s), as applicable and as each such term is defined below. If, during such ninety (90)-day period, Tenant in good faith questions or contests the correctness of
Landlord’s statement of Tenant’s Adjusted Share of Operating Expenses, Landlord shall provide Tenant with reasonable access to Landlord’s books and records to the extent relevant to determination of Operating Expenses, and such
information as Landlord reasonably determines to be responsive to Tenant’s written inquiries. In the event that, after Tenant’s review of such information, Landlord and Tenant cannot agree upon the amount of Tenant’s Adjusted Share of
Operating Expenses, then Tenant shall have the right to have an independent public accounting firm hired by Tenant on an hourly basis and not on a contingent-fee basis (at Tenant’s sole cost and expense) and approved by Landlord (which approval
Landlord shall not unreasonably withhold or delay) audit and review such of Landlord’s books and records for the year in question as directly relate to the determination of Operating Expenses for such year (the “Independent
Review”), but not books and records of entities other than Landlord. Landlord shall make such books and records available electronically if available, or at the location where Landlord maintains them in the ordinary course of its business.
Landlord need not provide copies of any books or records. Tenant shall commence the Independent Review within fifteen (15) days after the date Landlord has given Tenant access to Landlord’s books and records for the Independent Review.
Tenant shall complete the Independent Review and notify Landlord in writing of Tenant’s specific objections to Landlord’s calculation of Operating Expenses (including Tenant’s accounting firm’s written statement of the basis,
nature and amount of each proposed adjustment) no later than sixty (60) days after Landlord has first given Tenant access to Landlord’s books and records for the Independent Review. Landlord shall review the results of any such Independent
Review. The parties shall endeavor to agree promptly and reasonably upon Operating Expenses taking into account the results of such Independent Review. If, as of the date that is sixty (60) days after Tenant has submitted the Independent Review
to Landlord, the parties have not agreed on the appropriate adjustments to Operating Expenses, then the parties shall engage a mutually agreeable independent third party accountant with at least ten (10) years’ experience in commercial
real estate accounting in the Boston area (the “Accountant”). If the parties cannot 

  
 14 













 
agree on the Accountant, each shall within ten (10) days after such impasse appoint an Accountant (different from the accountant and accounting firm that conducted the Independent Review)
and, within ten (10) days after the appointment of both such Accountants, those two Accountants shall select a third (which cannot be the accountant and accounting firm that conducted the Independent Review). If either party fails to timely
appoint an Accountant, then the Accountant the other party appoints shall be the sole Accountant. Within ten (10) days after appointment of the Accountant(s), Landlord and Tenant shall each simultaneously give the Accountants (with a copy to
the other party) its determination of Operating Expenses, with such supporting data or information as each submitting party determines appropriate. Within ten (10) days after such submissions, the Accountants shall by majority vote select
either Landlord ‘s or Tenant’s determination of Operating Expenses. The Accountants may not select or designate any other determination of Operating Expenses. The determination of the Accountant(s) shall bind the parties. If the parties
agree or the Accountant(s) determine that the Operating Expenses actually paid by Tenant for the calendar year in question exceeded Tenant’s obligations for such calendar year, then Landlord shall, at Tenant’s option, either
(a) credit the excess to the next succeeding installments of estimated Additional Rent or (b) pay the excess to Tenant within thirty (30) days after delivery of such results. If the parties agree or the Accountant(s) determine that
Tenant’s payments of Operating Expenses for such calendar year were less than Tenant’s obligation for the calendar year, then Tenant shall pay the deficiency to Landlord within thirty (30) days after delivery of such results. 

9.5 Tenant shall not be responsible for Operating Expenses with respect to any time period prior to the Term Commencement Date;
provided, however, that if Landlord permits Tenant to occupy the Premises for the conduct of its business prior to the Term Commencement Date, and Tenant actually occupies the Premises for such purpose, Tenant shall be responsible for
Operating Expenses from such earlier date of possession (the Term Commencement Date or such earlier date, as applicable, the “Expense Trigger Date”); and provided, further, that Landlord may annualize certain Operating
Expenses incurred prior to the Expense Trigger Date over the course of the budgeted year during which the Expense Trigger Date occurs, and Tenant shall be responsible for the annualized portion of such Operating Expenses corresponding to the number
of days during such year, commencing with the Expense Trigger Date, for which Tenant is otherwise liable for Operating Expenses pursuant to this Lease. Tenant’s responsibility for Tenant’s Adjusted Share of Operating Expenses shall
continue to the latest of (a) the date of termination of the Lease, (b) the date Tenant has fully vacated the Premises and (c) if termination of the Lease is due to a default by Tenant, the date of rental commencement of a replacement
tenant. 
 9.6 Operating Expenses for the calendar year in which Tenant’s obligation to share therein commences and for the calendar
year in which such obligation ceases shall be prorated on a basis reasonably determined by Landlord. Expenses such as taxes, assessments and insurance premiums that are incurred for an extended time period shall be prorated based upon the time
periods to which they apply so that the amounts attributed to the Premises relate in a reasonable manner to the time period wherein Tenant has an obligation to share in Operating Expenses. 

  
 15 













 9.7 Tenant shall submit to Landlord an invoice, or, in the event an invoice is not
available, an itemized list, of all costs and expenses that (a) Tenant has incurred (either internally or by employing third parties) during the prior month and (b) for which Tenant reasonably believes it is entitled to reimbursements from
Landlord pursuant to the terms of this Lease, within forty-five (45) days after the end of each calendar month (or such longer period as needed, so long as it is provided within the calendar year in which such amounts were incurred). Landlord
shall pay any such amounts properly requested and due to Tenant under the terms of the Lease within forty-five (45) days of receipt of such invoice. 

9.8 In the event that the Building or Project is less than fully occupied during a calendar year, Tenant acknowledges that Landlord may
extrapolate Operating Expenses that vary depending on the occupancy of the Building or Project, as applicable, to equal Landlord’s reasonable estimate of what such Operating Expenses would have been had the Building or Project, as applicable,
been ninety-five percent (95%) occupied during such calendar year; provided, however, that Landlord shall not recover more than one hundred percent (100%) of Operating Expenses. 

10. Taxes on Tenant’s Property. 

10.1 Tenant shall be solely responsible for the payment of any and all taxes levied upon (a) personal property and trade fixtures located
at the Premises and (b) any gross or net receipts of or sales by Tenant, and shall pay the same at least twenty (20) days prior to delinquency. 

10.2 If any such taxes on Tenant’s personal property or trade fixtures are levied against Landlord or Landlord’s property or, if the
assessed valuation of the Building, the Property or the Project is increased by inclusion therein of a value attributable to Tenant ‘s personal property or trade fixtures, and if Landlord, after written notice to Tenant, pays the taxes based
upon any such increase in the assessed value of the Building, the Property or the Project, then Tenant shall, upon demand, repay to Landlord the taxes so paid by Landlord. 

10.3 If any improvements in or alterations to the Premises, whether owned by Landlord or Tenant and whether or not affixed to the real property
so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which improvements conforming to Landlord’s building standards (the “Building Standard”) in other spaces in
the Building are assessed, then the real property taxes and assessments levied against Landlord or the Building, the Property or the Project by reason of such excess assessed valuation shall be deemed to be taxes levied against personal property of
Tenant and shall be governed by the provisions of Section 10.2. Any such excess assessed valuation due to improvements in or alterations to space in the Project leased by other tenants at the Project shall not be included in Operating
Expenses. If the records of the applicable governmental assessor’s office are available and sufficiently detailed to serve as a basis for determining whether such Tenant improvements or alterations are assessed at a higher valuation than the
Building Standard, then such records shall be binding on both Landlord and Tenant. 
 11. Security Deposit. 

11.1 Tenant shall deposit with Landlord on or before the Execution Date the sum set forth in Section 2.6 (the “Security
Deposit”), which sum shall be held by Landlord as security for the faithful performance by Tenant of all of the terms, covenants and conditions of this Lease to be kept and performed by Tenant. If Tenant Defaults (as defined below) with
respect to any provision of this Lease, including any provision relating to the payment of Rent, then Landlord 

  
 16 













 
may (but shall not be required to) use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum in default, or to compensate Landlord for any other
loss or damage that Landlord may suffer by reason of Tenant’s default. If any portion of the Security Deposit is so used or applied, then Tenant shall, within ten (10) days following demand therefor, deposit cash with Landlord in an amount
sufficient to restore the Security Deposit to its original amount, and Tenant’s failure to do so shall be a material breach of this Lease. The provisions of this Article shall survive the expiration or earlier termination of this Lease. 

11.2 In the event of bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be applied first
to the payment of Rent and other charges due Landlord for all periods prior to the filing of such proceedings. 
 11.3 Landlord shall deliver
to any purchaser of Landlord’s interest in the Premises the funds deposited hereunder by Tenant, and thereupon Landlord shall be discharged from any further liability with respect to such deposit. This provision shall also apply to any
subsequent transfers. 
 11.4 Provided there is no default by Tenant under the Lease, then the Security Deposit, or any balance thereof,
shall be returned to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder) within sixty (60) days after the expiration or earlier termination of this Lease. 

11.5 If the Security Deposit shall be in cash, Landlord shall hold the Security Deposit in an account at a banking organization selected by
Landlord; provided, however, that Landlord shall not be required to maintain a separate account for the Security Deposit, but may intermingle it with other funds of Landlord. Landlord shall be entitled to all interest and/or dividends,
if any, accruing on the Security Deposit. Landlord shall not be required to credit Tenant with any interest for any period during which Landlord does not receive interest on the Security Deposit. 

11.6 The Security Deposit may be in the form of cash, a letter of credit or any other security instrument acceptable to Landlord in its sole
discretion. Tenant may at any time, except when Tenant is in Default (as defined below), deliver a letter of credit (the “L/C Security”) as the entire Security Deposit, as follows: 

(a) If Tenant elects to deliver L/C Security, then Tenant shall provide Landlord, and maintain in full force and effect throughout the Term and
until the date that is three (3) months after the then-current Term Expiration Date, a letter of credit in the form of Exhibit E issued by an issuer reasonably satisfactory to Landlord, in the amount of the Security Deposit, with an
initial term of at least one year. Landlord may require the L/C Security to be re-issued by a different issuer at any time during the Term if Landlord reasonably believes that the issuing bank of the L/C Security is or may soon become insolvent;
provided, however, Landlord shall return the existing L/C Security to the existing issuer immediately upon receipt of the substitute L/C Security. If any issuer of the L/C Security shall become insolvent or placed into FDIC receivership, then Tenant
shall immediately deliver to Landlord (without the requirement of notice from Landlord) substitute L/C Security issued by an issuer reasonably satisfactory to Landlord, and otherwise conforming to the requirements set forth in this Article. As used
herein with respect to the issuer of the L/C Security, “insolvent” means the determination of insolvency as made by such issuer’s primary bank regulator (i.e., the state bank supervisor for state chartered banks; the OCC or OTS,


  
 17 













 
respectively, for federally chartered banks or thrifts; or the Federal Reserve for its member banks). If, at the Term Expiration Date, any Rent remains uncalculated or unpaid, then
(i) Landlord shall with reasonable diligence complete any necessary calculations, (ii) Tenant shall extend the expiry date of such L/C Security from time to time as Landlord reasonably requires and (iii) in such extended period,
Landlord shall not unreasonably refuse to consent to an appropriate reduction of the L/C Security. Tenant shall reimburse Landlord’s legal costs (as estimated by Landlord’s counsel) in handling Landlord’s acceptance of L/C Security or
its replacement or extension. 
 (b) If Tenant delivers to Landlord satisfactory L/C Security in place of the entire Security Deposit,
Landlord shall remit to Tenant any cash Security Deposit Landlord previously held. 
 (c) Landlord may draw upon the L/C Security, and hold
and apply the proceeds in the same manner and for the same purposes as the Security Deposit, if (i) an uncured Default (as defined below) exists, (ii) as of the date that is thirty (30) days before any L/C Security expires (even if
such scheduled expiry date is after the Term Expiration Date) Tenant has not delivered to Landlord an amendment or replacement for such L/C Security, reasonably satisfactory to Landlord, extending the expiry date to the earlier of (1) three
(3) months after the then-current Term Expiration Date or (2) the date that is one year after the then-current expiry date of the L/C Security, (iii) the L/C Security provides for automatic renewals, Landlord asks the issuer to
confirm the current L/C Security expiry date, and the issuer fails to do so within ten (10) business days, (iv) Tenant fails to pay (when and as Landlord reasonably requires) any bank charges for Landlord’s transfer of the L/C
Security or (v) the issuer of the L/C Security ceases, or announces that it will cease, to maintain an office in the city where Landlord may present drafts under the L/C Security (and fails to permit drawing upon the L/C Security by overnight
courier or facsimile). This Section does not limit any other provisions of this Lease allowing Landlord to draw the L/C Security under specified circumstances. 

(d) Tenant shall not seek to enjoin, prevent, or otherwise interfere with Landlord’s draw under L/C Security, even if it violates this
Lease. Tenant acknowledges that the only effect of a wrongful draw would be to substitute a cash Security Deposit for L/C Security, causing Tenant no legally recognizable damage. Landlord shall hold the proceeds of any draw in the same manner and
for the same purposes as a cash Security Deposit. In the event of a wrongful draw, the parties shall cooperate to allow Tenant to post replacement L/C Security simultaneously with the return to Tenant of the wrongfully drawn sums, and Landlord shall
upon request confirm in writing to the issuer of the L/C Security that Landlord’s draw was erroneous. 
 (e) If Landlord transfers its
interest in the Premises, then Tenant shall at Tenant’s expense, within five (5) business days after receiving a request from Landlord, deliver (and, if the issuer requires, Landlord shall consent to) an amendment to the L/C Security
naming Landlord’s grantee as substitute beneficiary. If the required Security Deposit changes while L/C Security is in force, then Tenant shall deliver (and, if the issuer requires, Landlord shall consent to) a corresponding amendment to the
L/C Security. 

  
 18 













 12. Use. 

12.1 Tenant shall use the Premises for the Permitted Use, and shall not use the Premises, or permit or suffer the Premises to be used, for any
other purpose without Landlord’s prior written consent, which consent Landlord may withhold in its sole and absolute discretion. Tenant shall be prohibited from using the Premises or any portion of the Property for the sale, distribution or
production of marijuana. 
 12.2 Tenant shall not use or occupy the Premises in violation of Applicable Laws; zoning ordinances; or the
certificate of occupancy (or its substantial equivalent) issued for the Building or the Project, and shall, upon five (5) days’ written notice from Landlord, discontinue any use of the Premises that is declared or claimed by any
Governmental Authority having jurisdiction to be a violation of any of the above, or that in Landlord’s reasonable opinion violates any of the above. Tenant shall take such further actions and execute such further documents in connection with
this Lease as are necessary to comply with Applicable Laws relating to privacy, personal information and data security. Tenant acknowledges that Landlord may collect certain personal information (e.g., names, email addresses and contact information)
of Tenant’s and its affiliates’ employees (and, if applicable, subcontractors and consultants), and use such information in connection with performing Landlord’s duties and obligations, and exercising its rights under this Lease.
Tenant shall not retain, use or disclose any personal information received from Landlord pursuant to this Lease for any purpose other than to perform its duties and obligations, and exercise its rights under this Lease or as required by Applicable
Law. In the event of a conflict between this Section and Article 38, this Section shall govern. Tenant shall comply with any direction of any Governmental Authority having jurisdiction that shall, by reason of the nature of Tenant’s use
or occupancy of the Premises, impose any duty upon Tenant or Landlord with respect to the Premises or with respect to the use or occupation thereof, and shall indemnify, defend (at the option of and with counsel reasonably acceptable to the
indemnified party(ies)), save, reimburse and hold harmless (collectively, “Indemnify,” “Indemnity” or “Indemnification,” as the case may require) Landlord and its affiliates, employees, agents and
contractors; and any lender, mortgagee, ground lessor or beneficiary (each, a “Lender” and, collectively with Landlord and its affiliates, employees, agents and contractors, the “Landlord Indemnitees”) harmless from
and against any and all demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages, suits or judgments, and all reasonable expenses (including reasonable attorneys’ fees, charges and disbursements, regardless of
whether the applicable demand, claim, action, cause of action or suit is voluntarily withdrawn or dismissed) incurred in investigating or resisting the same (collectively, “Claims”) of any kind or nature that arise before, during or
after the Term as a result of Tenant’s breach of this Section. Landlord shall comply with all Applicable Laws with respect to Landlord’s performance of its services under this Lease. 

12.3 Tenant shall not do or permit to be done anything that will invalidate or increase the cost of any fire, environmental, extended coverage
or any other insurance policy covering the Building or the Project, and shall comply with all rules, orders, regulations and requirements of the insurers of the Building and the Project, and Tenant shall promptly, upon demand, reimburse Landlord for
any additional premium charged for such policy by reason of Tenant’s failure to comply with the provisions of this Article. 

  
 19 













 12.4 Tenant shall keep all doors opening onto public corridors closed, except when in use
for ingress and egress. 
 12.5 No additional locks or bolts of any kind shall be placed upon any of the doors or windows by Tenant, nor
shall any changes be made to existing locks or the mechanisms thereof without Landlord’s prior written consent. Tenant shall, upon termination of this Lease, return to Landlord all keys to offices and restrooms either furnished to or otherwise
procured by Tenant. In the event any key so furnished to Tenant is lost, Tenant shall pay to Landlord the cost of replacing the same or of changing the lock or locks opened by such lost key if Landlord shall deem it necessary to make such change.

 12.6 No awnings or other projections shall be attached to any outside wall of the Building. No curtains, blinds, shades or screens shall
be attached to or hung in, or used in connection with, any window or door of the Premises other than Landlord’s standard window coverings. Neither the interior nor exterior of any windows shall be coated or otherwise sunscreened without
Landlord’s prior written consent, nor shall any bottles, parcels or other articles be placed on the windowsills or items attached to windows that are visible from outside the Premises. No equipment, furniture or other items of personal property
shall be placed on any exterior balcony or terrace without Landlord’s prior written consent. 
 12.7 No sign, advertisement or notice
(“Signage”) shall be exhibited, painted or affixed by Tenant on any part of the Premises or the Building without Landlord’s prior written consent. Signage shall conform to Landlord’s design criteria established from time
to time. For any Signage, Tenant shall, at Tenant’s own cost and expense, (a) acquire all permits for such Signage in compliance with Applicable Laws and (b) design, fabricate, install and maintain such Signage in a first-class
condition. Tenant shall be responsible for reimbursing Landlord for costs incurred by Landlord in removing any of Tenant’s Signage upon the expiration or earlier termination of the Lease. Tenant shall have no right to install any exterior
Signage. Interior signs on entry doors to the Premises and the directory tablet shall be inscribed, painted or affixed for Tenant by Landlord at Landlord’s sole cost and expense, and shall be of a size, color and type and be located in a place
acceptable to Landlord. The directory tablet shall be provided exclusively for the display of the name and location of tenants only. Tenant shall not place anything on the exterior of the corridor walls or corridor doors other than Landlord’s
standard lettering. 
 12.8 Tenant may only place equipment within the Premises with floor loading consistent with the Building’s
structural design unless Tenant obtains Landlord’s prior written approval. Tenant may place such equipment only in a location designed to carry the weight of such equipment. 

12.9 Tenant shall cause any equipment or machinery to be installed in the Premises so as to reasonably prevent sounds or vibrations therefrom
from extending into the Common Area or other leased premises in the Project.

 12.10 Tenant shall not (a) do or permit anything to be done in or about the Premises
that shall in any way obstruct or interfere with the rights of other tenants or occupants of the Project, or injure them, (b) use or allow the Premises to be used for unlawful purposes, (c) cause, maintain or permit any nuisance or waste
in, on or about the Project or (d) take any other action that would in Landlord’s reasonable determination in any manner adversely affect other tenants’ quiet use and enjoyment of their space or adversely impact their ability to
conduct business in a professional and suitable work environment. Landlord shall be responsible for delivering the Premises in compliance with Appliable Laws including the ADA. Notwithstanding any other provision herein to the contrary, Tenant shall
be responsible for all liabilities, costs and expenses arising from or in connection with the compliance of the Premises after the Term Commencement Date with the Americans with Disabilities Act, 42 U.S.C. § 12101, et seq., and any state and
local accessibility laws, codes, ordinances and rules (collectively, and together with regulations promulgated pursuant thereto, the “ADA”), and Tenant shall Indemnify the Landlord Indemnitees from and against any Claims arising
from any such failure of the Premises to comply with the ADA. This Section (as well as any other provisions of this Lease dealing with Indemnification of the Landlord Indemnitees by Tenant) shall be deemed to be modified in each case by the
insertion in the appropriate place of the following: “except as otherwise provided in Mass. G.L. Ter. Ed., C. 186, Section 15.” For the avoidance of doubt, “Lenders” shall also include historic tax credit investors and new
market tax credit investors. Landlord represents and warrants that to the actual knowledge of Landlord without any duty of investigation the Common Areas shall be in compliance with the ADA as of the Term Commencement Date. The provisions of this
Section shall survive the expiration or earlier termination of this Lease. 
 12.11 Tenant shall establish and maintain a chemical safety
program administered by a licensed, qualified individual in accordance with the requirements of the Massachusetts Water Resources Authority (“MWRA”) and any other applicable Governmental Authority. Tenant shall be solely responsible
for all costs incurred in connection with such chemical safety program, and Tenant shall provide Landlord with such documentation as Landlord may reasonably require evidencing Tenant’s compliance with the requirements of (a) the MWRA and
any other applicable Governmental Authority with respect to such chemical safety program and (b) this Section. Notwithstanding the foregoing, Landlord shall obtain and maintain during the Term (m) any permit required by the MWRA
(“MWRA Permit”) and (n) a wastewater treatment operator license from the Commonwealth of Massachusetts with respect to Tenant’s use of the Acid Neutralization Tank (as defined below) in the Building. Tenant shall not
introduce anything into the Acid Neutralization Tank (x) in violation of the terms of the MWRA Permit, (y) in violation of Applicable Laws or (z) that would interfere with the proper functioning of the Acid Neutralization Tank. Tenant
agrees to reasonably cooperate with Landlord in order to obtain the MWRA Permit and the wastewater treatment operator license. Tenant shall reimburse Landlord within ten (10) business days after demand for any costs incurred by Landlord
pursuant to this Section. 
 13. Rules and Regulations, CC&Rs, Parking Facilities and Common Area. 

13.1 Tenant shall have the non-exclusive right, in common with others, to use the Common Area in conjunction with Tenant’s use of the
Premises for the Permitted Use, and such use of the Common Area and Tenant’s use of the Premises shall be subject to the rules and regulations adopted by Landlord and attached hereto as Exhibit F, together with such other reasonable and
nondiscriminatory rules and regulations as are hereafter promulgated by Landlord in its sole and absolute discretion (the “Rules and Regulations”). Tenant shall and shall ensure that its contractors, subcontractors, employees,
subtenants and invitees faithfully observe and comply with the Rules and Regulations. Landlord shall not be responsible to Tenant for the violation or non-performance by any other tenant or any agent, employee or invitee thereof of any of the Rules
and Regulations. 

  
 21 













 13.2 This Lease is subject to any recorded covenants, conditions or restrictions on the
Project or Property, as the same may be amended, amended and restated, supplemented or otherwise modified from time to time (the “CC&Rs”), provided any such amendments shall not materially adversely affect Tenant or increase
Tenant’s obligations hereunder. Tenant shall, at its sole cost and expense, comply with the CC&Rs. 
 13.3 Notwithstanding anything
in this Lease to the contrary, Tenant may not install any security systems (including cameras) outside the Premises or that record sounds or images outside the Premises without Landlord’s prior written consent, which Landlord may withhold in
its sole and absolute discretion. 
 13.4 Tenant acknowledges that, pursuant to that certain Transportation Access Plan Agreement dated as of
October 12, 2017 (as the same may be amended or superseded, the “TAPA”), a copy of which is attached hereto as Exhibit G, Tenant shall at its sole cost take measures to promote public transportation and subsidize
employee use of public transit including providing fifty percent (50%) MBTA pass subsidies for full-time and part-time employees. Tenant, at its sole cost and expense, shall also comply with the reporting requirements set forth in the TAPA at
Landlord’s request. Any costs incurred by Landlord in connection with the TAPA shall constitute an Operating Expense. 
 13.5 Tenant
shall have a non-exclusive, irrevocable license to use sixteen (16) parking spaces at the parking facilities serving the Building in common on an unreserved basis with other tenants of the Project during the Term at an initial cost of Four
Hundred Dollars ($400.00) per parking space per month (which rate shall be subject to periodic market adjustments), which Tenant shall pay simultaneously with payments of Base Rent as Additional Rent, commencing on the Term Commencement Date. 

13.6 Tenant agrees not to unreasonably overburden the parking facilities and agrees to cooperate with Landlord and other tenants in the use of
the parking facilities in accordance with and subject to the Rules and Regulations. Landlord reserves the right to determine that parking facilities are becoming overcrowded and to limit Tenant’s use thereof. Upon such determination, Landlord
may reasonably allocate parking spaces among Tenant and other tenants of the Building or the Project. Nothing in this Section, however, is intended to create an affirmative duty on Landlord’s part to monitor parking. 

13.7 Subject to the terms of this Lease including the Rules and Regulations and the rights of other tenants of the Project, Tenant shall have
the non-exclusive right to access the freight loading dock during dock operating hours as set by Landlord at no additional cost, or those times arranged in advance with building management at Tenant’s cost. In addition, subject to the terms of
this Lease including the Rules and Regulations and the rights of other tenants in the Project, Tenant shall have the non-exclusive right to access the freight elevator 24/7 for moving freight or other items restricted from being moved in a passenger
elevator, subject to the issuance of access passes by Landlord to qualified individuals, at no additional cost. 

  
 22 













 14. Project Control by Landlord. 

14.1 Landlord reserves full control over the Building and the Project to the extent not inconsistent with Tenant’s enjoyment of the
Premises as provided by this Lease and to the extent such control will not create additional liability for Tenant under this Lease or deprive Tenant of the quiet enjoyment and use of the Premises. This reservation includes Landlord’s right to
subdivide the Project; convert the Building and the other buildings within the Project to condominium units; change the size of the Project by selling all or a portion of the Project or adding real property and any improvements thereon to the
Project; grant easements and licenses to third parties; maintain or establish ownership of the Building separate from fee title to the Property; make additions to or reconstruct portions of the Building and the Project; install, use, maintain,
repair, replace and relocate for service to the Premises and other parts of the Building or the Project (including to other tenant premises) pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises, the Building or
elsewhere at the Project or delegate such rights to other tenants performing work in their respective premises; and alter or relocate any other Common Area or facility, including private drives, lobbies, elevators, loading areas, entrances and
landscaping; provided, however, that such rights shall be exercised in a way that does not materially adversely affect Tenant’s beneficial use and occupancy of the Premises, including the Permitted Use and Tenant’s access to
the Premises, and in a way that does not reduce Tenant’s useable square footage. Tenant acknowledges that Landlord specifically reserves the right to allow the exclusive use of corridors and restroom facilities located on specific floors to one
or more tenants occupying such floors; provided, however, that Tenant shall not be deprived of the use of the corridors reasonably required to serve the Premises or of restroom facilities serving the floor upon which the Premises are
located. Tenant acknowledges that the Building is under development, that there may be construction in the Common Areas and other tenant premises in the Building from time to time during the Term, and that Landlord shall not be liable for any rent
abatement or compensation by reason of inconvenience, annoyance, or loss of business resulting from such construction. Further, Tenant shall be responsible for taking any precautions Tenant deems necessary with respect to its business operations in
the Premises to mitigate construction impacts such as sound and vibration from other parts of the Project. 
 14.2 Possession of areas of the
Premises necessary for utilities, services, safety and operation of the Building is reserved to Landlord. 
 14.3 Tenant shall, at
Landlord’s request, promptly execute such further documents as may be reasonably appropriate to assist Landlord in the performance of its obligations hereunder; provided that Tenant need not execute any document that creates additional
liability for Tenant or that deprives Tenant of the quiet enjoyment and use of the Premises, as provided for in this Lease. 
 14.4 Landlord
may, at any and all reasonable times during business hours (or during non-business hours, if (a) with respect to Subsections 14.4(u) through 14.4(y), Tenant so requests, and (b) with respect to Subsection 14.4(z), if
Landlord so requests), and upon twenty-four (24) hours’ prior notice (which may be oral or by email to the office manager or other Tenant-designated individual at the Premises; but provided that no time restrictions shall apply or
advance notice be required if an emergency necessitates immediate entry), enter the Premises to (u) inspect the same and to determine whether Tenant is in compliance with its obligations hereunder, (v) supply any service Landlord is
required to provide hereunder, (w) alter, improve or repair any 

  
 23 













 
portion of the Building other than the Premises for which access to the Premises is reasonably necessary, (x) post notices of nonresponsibility, (y) access the telephone equipment,
electrical substation and fire risers and (z) show the Premises to prospective tenants during the final year of the Term and current and prospective purchasers and lenders at any time, or permit a future tenant of the Premises to inspect and
measure the Premises in anticipation of such tenant’s future occupancy of the Premises. Notwithstanding the foregoing, Tenant shall have the right to have a representative of Tenant accompany Landlord at such times; provided, however, if
Tenant’s representative is not available or does not elect to accompany Landlord at the times that Landlord has requested access, then such unavailability shall not prohibit or otherwise restrict Landlord’s access, and Landlord may access
the Premises with or without Tenant’s representative present. In connection with any such alteration, improvement or repair as described in Subsection 14.4(w), Landlord may erect in the Premises or elsewhere in the Project scaffolding
and other structures reasonably required for the alteration, improvement or repair work to be performed. In no event shall Tenant’s Rent abate as a result of Landlord’s activities pursuant to this Section; provided, however,
that all such activities shall be conducted in such a manner so as to cause as little interference to Tenant as is reasonably possible. Landlord shall at all times retain a key with which to unlock all of the doors in the Premises. If an emergency
necessitates immediate access to the Premises, Landlord may use whatever force is necessary to enter the Premises, and any such entry to the Premises shall not constitute a forcible or unlawful entry to the Premises, a detainer of the Premises, or
an eviction of Tenant from the Premises or any portion thereof. 
 15. Quiet Enjoyment. Landlord covenants that Tenant, upon paying the Rent and
performing its obligations contained in this Lease, may peacefully and quietly have, hold and enjoy the Premises, free from any claim by Landlord or persons claiming under Landlord, but subject to all of the terms and provisions hereof, provisions
of Applicable Laws and rights of record to which this Lease is or may become subordinate. This covenant is in lieu of any other quiet enjoyment covenant, either express or implied. 

16. Utilities and Services. 
 16.1
Commencing on the Term Commencement Date, Tenant shall pay for all water (including the cost to service, repair and replace reverse osmosis, de-ionized and other treated water), gas, heat, light, power, telephone, internet service, cable television,
other telecommunications and other utilities supplied to the Premises, together with any fees, surcharges and taxes thereon. If any such utility is not separately metered to Tenant, Tenant shall pay Tenant’s Adjusted Share of all charges of
such utility jointly metered with other premises as Additional Rent or, in the alternative, Landlord may, at its option, monitor the usage of such utilities by Tenant and charge Tenant with the cost of purchasing, installing and monitoring such
metering equipment, which cost shall be paid by Tenant as Additional Rent. 
 16.2 Landlord may base its bills for utilities on reasonable
estimates; provided that Landlord adjusts such billings as part of the next Landlord’s Statement (or more frequently, as determined by Landlord) to reflect the actual cost of providing utilities to the Premises. To the extent that Tenant
uses more than Tenant’s Pro Rata Share of any utilities, then Tenant shall pay Landlord for Tenant’s Adjusted Share of such utilities to reflect such excess. In the event that the Building or Project is less than fully occupied during a
calendar year, Tenant acknowledges that Landlord may extrapolate utility usage that varies depending on the occupancy of the Building or Project (as applicable) to equal Landlord’s reasonable estimate of what such utility usage would have been
had the Building or Project, as applicable, been ninety-five percent (95%) occupied during such calendar year; provided, however, that Landlord shall not recover more than one hundred percent (100%) of the cost of such
utilities. 

  
 24 













 16.3 Landlord shall not be liable for, nor shall any eviction of Tenant result from, the
failure to furnish any utility or service, whether or not such failure is caused by Force Majeure (as defined below) or, to the extent permitted by Applicable Laws, Landlord’s negligence. In the event of such failure, Tenant shall not be
entitled to termination of this Lease or any abatement or reduction of Rent, nor shall Tenant be relieved from the operation of any covenant or agreement of this Lease. Notwithstanding anything to the contrary in this Lease, if, for more than five
(5) consecutive business days following written notice to Landlord and as a direct result of Landlord’s gross negligence or willful misconduct (and except to the extent that such failure is caused by any other factor, including any action
or inaction of a Tenant Party (as defined below)), the provision of HVAC or other utilities to all or a material portion of the Premises that Landlord must provide pursuant to this Lease is interrupted (a “Material Services
Failure”), then Base Rent and Tenant’s Adjusted Share of Operating Expenses (or, to the extent that less than all of the Premises are affected, a proportionate amount (based on the Rentable Area of the Premises that is rendered
unusable) of Base Rent and Tenant’s Adjusted Share of Operating Expenses) shall thereafter be abated until the Premises are again usable by Tenant for the Permitted Use; provided, however, that, if Landlord is diligently pursuing the
restoration of such HVAC and other utilities and Landlord provides substitute HVAC and other utilities reasonably suitable for Tenant’s continued use and occupancy of the Premises for the Permitted Use (e.g., supplying potable water or portable
air conditioning equipment), then neither Base Rent nor Tenant’s Adjusted Share of Operating Expenses shall be abated. During any Material Services Failure, Tenant will cooperate with Landlord to arrange for the provision of any interrupted
utility services on an interim basis via temporary measures until final corrective measures can be accomplished, and Tenant will permit Landlord the necessary access to the Premises to remedy such Material Service Failure. In the event of any
interruption of HVAC or other utilities that Landlord must provide pursuant to this Lease, regardless of the cause, Landlord shall diligently pursue the restoration of such HVAC and other utilities. Notwithstanding anything in this Lease to the
contrary, but subject to Article 24 (which shall govern in the event of a casualty), the provisions of this Section shall be Tenant’s sole recourse and remedy in the event of an interruption of HVAC or other utilities to the Premises,
including related to Section 16.8. 
 16.4 Tenant shall pay for, prior to delinquency of payment therefor, any utilities and
services that may be furnished to the Premises during or, if Tenant occupies the Premises after the expiration or earlier termination of the Term, after the Term, beyond those utilities provided by Landlord, including telephone, internet service,
cable television and other telecommunications, together with any fees, surcharges and taxes thereon. Upon Landlord’s demand, utilities and services provided to the Premises that are separately metered shall be paid by Tenant directly to the
supplier of such utilities or services. 
 16.5 Tenant shall not, without Landlord’s prior written consent, use any device in the
Premises (including data processing machines) that will in any way (a) increase the amount of ventilation, air exchange, gas, steam, electricity or water required or consumed in the Premises based upon Tenant’s Pro Rata Share of the
Building or Project (as applicable) beyond the existing capacity of the Building or the Project usually furnished or supplied for the Permitted Use or (b) exceed Tenant’s Pro Rata Share of the Building’s or Project’s (as
applicable) capacity to provide such utilities or services. 

  
 25 













 16.6 If Tenant shall require utilities or services in excess of those usually furnished or
supplied for tenants in similar spaces in the Building or the Project by reason of Tenant’s equipment or extended hours of business operations, then Tenant shall first procure Landlord’s consent for the use thereof, which consent Landlord
may condition upon the availability of such excess utilities or services, and Tenant shall pay as Additional Rent an amount equal to the cost of providing such excess utilities and services. 

16.7 Landlord shall bring cold water to the point of connection with the Premises and shall provide hot and cold water in Common Area for
lavatory and landscaping purposes only, which water shall be from the local municipal or similar source; provided, however, that if Landlord determines that Tenant requires, uses or consumes water provided to the Common Area for any
purpose other than ordinary lavatory purposes, Landlord may install a water meter (“Tenant Water Meter”) and thereby measure Tenant’s water consumption for all purposes. Tenant shall pay Landlord for the costs of any Tenant
Water Meter and the installation and maintenance thereof during the Term. If Landlord installs a Tenant Water Meter, Tenant shall pay for water consumed, as shown on such meter, as and when bills are rendered. If Tenant fails to timely make such
payments, Landlord may pay such charges and collect the same from Tenant. Any such costs or expenses incurred or payments made by Landlord for any of the reasons or purposes stated in this Section shall be deemed to be Additional Rent payable by
Tenant and collectible by Landlord as such. 
 16.8 Landlord reserves the right, on at least twenty-four (24) hours’ advance notice
(which may be orally or by email) to stop service of the elevator, plumbing, ventilation, air conditioning and utility systems, when Landlord deems necessary or desirable, or due to accident or emergency (in which case no notice shall be required),
or the need to make repairs, alterations or improvements, until such repairs, alterations or improvements shall have been completed, and except as provided in Section 16.3, Landlord shall further have no responsibility or liability for
failure to supply elevator facilities, plumbing, ventilation, air conditioning or utility service when prevented from doing so by Force Majeure (as defined below) or, to the extent permitted by Applicable Laws, Landlord’s negligence (but not
gross negligence). Without limiting the foregoing, it is expressly understood and agreed that any covenants on Landlord’s part to furnish any service pursuant to any of the terms, covenants, conditions, provisions or agreements of this Lease,
or to perform any act or thing for the benefit of Tenant, shall not be deemed breached if Landlord is unable to furnish or perform the same by virtue of Force Majeure or, to the extent permitted by Applicable Laws, Landlord’s negligence (but
not gross negligence). 
 16.9 Landlord will install a back-up generator and connect the Generator to the Premises’ emergency electrical
panel (the “Generator”). Tenant shall be entitled to use up to its proportionate share (after deducting any power from the Generator required for the Common Area) of power from the Generator on a non-exclusive basis with other
tenants in the Building in accordance with the Design Manual attached to Exhibit F hereto. The cost of maintaining, repairing and replacing the Generator shall constitute Operating Expenses. Landlord expressly disclaims any warranties with
regard to the Generator or the installation thereof, including any 

  
 26 













 
warranty of merchantability or fitness for a particular purpose. Landlord shall maintain the Generator and any equipment connecting the Generator to Tenant’s automatic transfer switch in
good working condition, provided, however, that Tenant shall be solely responsible, at Tenant’s sole cost and expense, (and Landlord shall not be liable) for maintaining and operating Tenant’s automatic transfer switch and
the distribution of power from Tenant’s automatic transfer switch throughout the Premises, and provided further that Landlord shall not be liable for any failure to make any repairs or to perform any maintenance of the Generator that is an
obligation of Landlord unless and except to the extent that Landlord willfully fails to make such repairs or perform such maintenance and such failure persists for an unreasonable time after Tenant provides Landlord with written notice of the need
for such repairs or maintenance. Upon receipt of such written notice, Landlord shall promptly commence to cure such failure and shall diligently prosecute the same to completion in accordance with Section 31.13. The provisions of
Section 16.3 shall apply to the Generator. 
 16.10 For the Premises, Landlord shall (a) maintain and operate the base
building HVAC systems (not including supplemental units exclusively serving the Premises) used for the Permitted Use only (“Base HVAC”) and (b) furnish HVAC as reasonably required (except as this Lease otherwise provides or as
to any special requirements that arise from Tenant’s particular use of the Premises) for reasonably comfortable occupancy of the Premises twenty-four (24) hours a day, every day during the Term, subject to casualty, eminent domain or as
otherwise specified in this Article. Notwithstanding anything to the contrary in this Section, Landlord shall have no liability, and Tenant shall have no right or remedy, on account of any interruption or impairment in HVAC services, except as
provided in Section 16.2. 
 16.11 For any utilities serving the Premises for which Tenant is billed directly by such utility
provider, Tenant agrees to furnish to Landlord (a) within thirty (30) days after Landlord’s request, any utility usage information reasonably requested by Landlord, and (b) within thirty (30) days after each calendar year
during the Term, authorization to allow Landlord to access Tenant’s usage information necessary for Landlord to complete an ENERGY STAR® Statement of Performance (or similar comprehensive
utility usage report (e.g., related to Labs 21), if requested by Landlord) and any other information reasonably requested by Landlord for the immediately preceding year; and Tenant shall comply with any other energy usage or consumption requirements
required by Applicable Laws. Tenant shall retain records of utility usage at the Premises, including invoices and statements from the utility provider, for at least sixty (60) months, or such other period of time as may be requested by
Landlord. Tenant acknowledges that any utility information for the Premises, the Building and the Project may be shared with third parties, including Landlord’s consultants and Governmental Authorities. In the event that Tenant fails to comply
with this Section, Tenant hereby authorizes Landlord to collect utility usage information directly from the applicable utility providers, and Tenant shall pay Landlord a fee of Five Hundred Dollars ($500) per month to collect such utility usage
information. In addition to the foregoing, Tenant shall comply with all Applicable Laws related to the disclosure and tracking of energy consumption at the Premises. The provisions of this Section shall survive the expiration or earlier termination
of this Lease. 

  
 27 













 16.12 The Building shall be serviced by a common laboratory waste sanitary sewer connection
from the pH neutralization room located in the third floor mechanical room of the Building to the municipal sewer line in the street adjacent to the Building. There shall be a separate acid neutralization tank (the “Acid Neutralization
Tank”) that is connected to the Premises, as well as to other premises in the Building. Tenant shall install sampling ports in lab waste plumbing. Tenant shall have a non-exclusive right to use its proportionate share of the Acid
Neutralization Tank in accordance with Applicable Laws in common with other tenants of the Building. Tenant, as a portion of its Operating Expenses, shall reimburse Landlord for all costs, charges and expenses incurred by Landlord from time to time
in connection with or arising from the operation, use, maintenance, repair or refurbishment of the Acid Neutralization Tank, including all clean-up costs relating to the Acid Neutralization Tank (collectively, “Tank Costs”);
provided, however, that if the Acid Neutralization Tank is being used by other tenant(s) or occupant(s) of the Building at any time during the Term, then, during such time period, Tenant shall only be obligated to pay its proportionate
share of the Tank Costs. Notwithstanding the foregoing, in the event the Acid Neutralization Tank is damaged or repairs to the Acid Neutralization Tank are required as a result of the improper use of the Acid Neutralization Tank by Tenant, Tenant
shall be responsible for one hundred percent (100%) of the cost of any repairs or replacement required as a result of such improper use by Tenant, regardless of whether the Acid Neutralization Tank is then being used by other tenant(s) or
occupant(s) of the Building. Similarly, if the Acid Neutralization Tank is damaged, or if repairs to the Acid Neutralization Tank are required as a result of the improper use of the Acid Neutralization Tank by other tenant(s) or occupant(s) of the
Building, then Tenant shall have no responsibility for the cost of any repairs or replacements required as a result of such improper use by such other tenant(s) or occupant(s). Tenant shall Indemnify the Landlord Indemnitees from and against any and
all Claims, including (a) diminution in value of the Project or any portion thereof, (b) damages for the loss or restriction on use of rentable or usable space or of any amenity of the Project, (c) damages arising from any adverse
impact on marketing of space in the Project or any portion thereof and (d) sums paid in settlement of Claims that arise during or after the Term as a result of Tenant’s improper use of the Acid Neutralization Tank. This Indemnification by
Tenant includes costs incurred in connection with any investigation of site conditions or any clean-up, remediation, removal or restoration required by any Governmental Authority arising from Tenant’s improper use of the Acid Neutralization
Tank. 
 17. Alterations. 
 17.1 Tenant
shall make no alterations, additions or improvements in or to the Premises or engage in any construction, demolition, reconstruction, renovation or other work (whether major or minor) of any kind in, at or serving the Premises
(“Alterations”) without Landlord’s prior written approval, which approval Landlord shall not unreasonably withhold, condition or delay; provided, however, that, in the event any proposed Alteration affects (a) any
structural portions of the Building, including exterior walls, the roof, the foundation or slab, foundation or slab systems (including barriers and subslab systems) or the core of the Building, (b) the exterior of the Building or (c) any
Building systems, including elevator, plumbing, HVAC, electrical, security, life safety and power, then Landlord may withhold its approval in its sole and absolute discretion. Notwithstanding the foregoing, Tenant may make strictly cosmetic changes
to the Premises that do not require any permits or more than three (3) total contractors and subcontractors (“Cosmetic Alterations”) without Landlord’s consent; provided that (y) the cost of any Cosmetic
Alterations does not exceed One Hundred Thousand Dollars ($100,000) in the aggregate, (z) such Cosmetic Alterations do not (i) require any structural or other substantial modifications to the Premises, (ii) require any changes to or
adversely affect the Building systems, (iii) affect the exterior of the Building or (iv) trigger any requirement under Applicable Laws that would require Landlord to 

  
 28 













 
make any alteration or improvement to the Premises, the Building or the Project. Tenant shall give Landlord at least ten (10) days’ prior written notice of any Cosmetic Alterations.
Tenant shall, in making any Alterations, use only those architects, contractors, suppliers and mechanics of which Landlord has given prior written approval and Landlord may refuse to approve any architects, consultants, engineers, contractors,
subcontractors or material suppliers that Landlord reasonably believes could cause labor disharmony or may not have sufficient experience, in Landlord’s reasonable opinion, to perform work in an occupied Class “A” laboratory research
building and in lab areas. In seeking Landlord’s approval, Tenant shall provide Landlord, at least thirty (30) days in advance of the desired commencement date of any proposed construction, with plans, specifications, bid proposals,
certified stamped engineering drawings and calculations by Tenant’s engineer of record or architect of record (including connections to the Building’s structural system, modifications to the Building’s envelope, non-structural
penetrations in slabs or walls, and modifications or tie-ins to life safety systems), work contracts, requests for laydown areas and such other information concerning the nature and cost of the Alterations as Landlord may reasonably request,
provided that Tenant shall not commence any such Alterations that require Landlord’s consent unless and until Tenant has received the written approval of Landlord. In no event shall Tenant use or Landlord be required to approve any architects,
consultants, contractors, subcontractors or material suppliers that Landlord reasonably believes could cause labor disharmony or may not have sufficient experience, in Landlord’s reasonable opinion, to perform work in an occupied Class
“A” laboratory research building and in lab areas. 
 17.2 Tenant shall not construct or permit to be constructed partitions or
other obstructions that might interfere with free access to mechanical installation or service facilities of the Building or with other tenants’ components located within the Building, or interfere with the moving of Landlord’s equipment
to or from the enclosures containing such installations or facilities. 
 17.3 Tenant shall accomplish any work performed on the Premises or
the Building in such a manner as to permit any life safety systems to remain fully operable at all times. 
 17.4 Any work performed on the
Premises, the Building or the Project by Tenant or Tenant’s contractors shall be done at such times and in such manner as Landlord may from time to time designate. Tenant covenants and agrees that all work done by Tenant or Tenant’s
contractors shall be performed in full compliance with Applicable Laws. Within thirty (30) days after completion of any Alterations, Tenant shall provide Landlord with complete “as built” drawing print sets and electronic CADD files
on disc (or files in such other current format in common use as Landlord reasonably approves or requires) showing any changes in the Premises, as well as a commissioning report prepared by a licensed, qualified commissioning agent hired by Tenant
and approved by Landlord for all new or affected mechanical, electrical and plumbing systems. Any such “as built” plans shall show the applicable Alterations as an overlay on the Building as-built plans; provided that Landlord
provides the Building “as built” plans to Tenant. 
 17.5 Before commencing any Alterations, Tenant shall give Landlord at least
thirty (30) days’ prior written notice of the proposed commencement of such work and the names and addresses of the persons supply labor or materials therefor so that Landlord may enter the Premises to post and keep posted thereon and
therein notices or to take any further action that Landlord may reasonably deem proper for the protection of Landlord’s interest in the Project. 

  
 29 













 17.6 Tenant shall repair any damage to the Premises arising from Tenant’s removal of
any property from the Premises. During any such restoration period, Tenant shall pay Rent to Landlord as provided herein as if such space were otherwise occupied by Tenant. The provisions of this Section shall survive the expiration or earlier
termination of this Lease. 
 17.7 The Premises plus any Alterations; Signage; Tenant Improvements; attached equipment, decorations, fixtures
and trade fixtures; movable laboratory casework and related appliances (but only to the extent installed as part of the Tenant Improvements); and other additions and improvements attached to or built into the Premises made by either of the parties
(including all floor and wall coverings; paneling; sinks and related plumbing fixtures; laboratory benches; exterior venting fume hoods; walk-in freezers and refrigerators; ductwork; conduits; electrical panels and circuits; attached machinery and
equipment; and built-in furniture and cabinets, in each case, together with all additions and accessories thereto), shall (unless, prior to such construction or installation, Landlord elects otherwise in writing) at all times remain the property of
Landlord, shall remain in the Premises and shall (unless, prior to construction or installation thereof, Landlord elects otherwise in writing) be surrendered to Landlord upon the expiration or earlier termination of this Lease. For the avoidance of
doubt, the items listed on Exhibit H attached hereto (which Exhibit H may be updated by Tenant from and after the Term Commencement Date, subject to Landlord’s written consent) constitute Tenant’s property and shall be
removed by Tenant upon the expiration or earlier termination of the Lease. Further, Landlord hereby agrees that Tenant shall not be required to remove any standard office or lab improvements or code compliant cabling from the Premises upon the
expiration or earlier termination of this Lease. 
 17.8 Notwithstanding any other provision of this Article to the contrary, in no event
shall Tenant remove any improvement from the Premises in which any Lender has a security interest or as to which Landlord contributed payment, including the Tenant Improvements, without Landlord’s prior written consent, which consent Landlord
may withhold in its sole and absolute discretion. 
 17.9 If Tenant shall fail to remove any of its property from the Premises prior to the
expiration or earlier termination of this Lease, then Landlord may, at its option, remove the same in any manner that Landlord shall choose and store such effects without liability to Tenant for loss thereof or damage thereto, and Tenant shall pay
Landlord, upon demand, any costs and expenses incurred due to such removal and storage or Landlord may, at its sole option and without notice to Tenant, sell such property or any portion thereof at private sale and without legal process for such
price as Landlord may obtain and apply the proceeds of such sale against any (a) amounts due by Tenant to Landlord under this Lease and (b) any expenses incident to the removal, storage and sale of such personal property. 

17.10 Except with respect to the Tenant Improvements which shall be subject to the terms of Section 4.4, the Tenant shall pay to
Landlord the actual out-of-pocket expenses incurred by Landlord in connection with the project management of any Alterations, including costs incurred for plan review, engineering review, coordination, scheduling and supervision thereof. Tenant
shall reimburse Landlord for any extra expenses incurred by Landlord by reason of faulty work done by Tenant or its contractors, or by reason of delays arising from such faulty work, or by reason of inadequate clean-up.

 17.11 Within sixty (60) days after final completion of any Alterations performed by
Tenant with respect to the Premises, Tenant shall submit to Landlord documentation showing the amounts expended by Tenant with respect to such Alterations, together with supporting documentation reasonably acceptable to Landlord. 

17.12 Tenant shall take, and shall cause its contractors to take, commercially reasonable steps to protect the Premises during the performance
of any Alterations, including covering or temporarily removing any window coverings so as to guard against dust, debris or damage. 
 17.13
Tenant shall require its contractors and subcontractors performing work on the Premises to name Landlord, BioMed Realty, L.P. and BioMed Realty III LP, and their respective officers, employees, directors, representatives, agents, general partners,
members, subsidiaries, affiliates and Lenders (collectively with Landlord, the “Landlord Parties”) as additional insureds on their respective insurance policies. 

18. Repairs and Maintenance. 
 18.1
Landlord shall repair and maintain in good condition and repair the structural and exterior portions and Common Area of the Building and the Project, including roofing and covering materials; foundations (excluding any architectural slabs, but
including any structural slabs); exterior walls; plumbing; fire sprinkler systems (if any); base Building HVAC systems up to the first damper or isolation valve that serves the Premises (for purposes of clarity, the portion of the HVAC system that
includes such first damper or isolation valve and extends into and through the Premises, and any supplemental HVAC serving the Premises shall not be part of the base Building HVAC and shall be Tenant’s obligation to maintain and repair pursuant
to Section 18.2 below); elevators; the Generator (excluding the automatic transfer switch); and base Building electrical systems installed or furnished by Landlord. 

18.2 Except for services of Landlord, if any, required by Section 18.1, Tenant shall at Tenant’s sole cost and expense
maintain and keep the Premises (including but not limited to the portion of the HVAC system that includes the first damper or isolation valve and extends into and through the Premises, any supplemental HVAC serving the Premises, and any other
systems or equipment exclusively serving the Premises) and every part thereof in good condition and repair, and shall, within ten (10) days after receipt of written notice from Landlord, provide to Landlord any maintenance records that Landlord
reasonably requests. Tenant shall, upon the expiration or sooner termination of the Term, surrender the Premises to Landlord in the condition required to be maintained during the Term, ordinary wear and tear excepted (unless required to restore or
repair hereunder following a casualty event); and shall, at Landlord’s request and Tenant’s sole cost and expense, remove all telephone and data systems, wiring (other than code compliant cabling) and equipment from the Premises, and
repair any damage to the Premises caused thereby. Landlord shall have no obligation to alter, remodel, improve, repair, decorate or paint the Premises or any part thereof, other than pursuant to the terms and provisions of this Lease, including the
Work Letter. 

  
 31 













 18.3 Throughout the Term of the Lease, Tenant shall, at Tenant’s sole cost and expense,
maintain copies of all service contracts, service, repair and maintenance records, and inspection reports on all equipment installed by or maintained by Tenant. Tenant shall, within ten (10) days after receipt of written notice from Landlord,
provide to Landlord any maintenance records, service or inspection reports that Landlord reasonably requests. Upon surrender of the Premises upon the expiration or earlier termination of this Lease, Tenant shall provide Landlord with all original
equipment manufacturer (OEM) manuals for any equipment installed and not removed by Tenant. Landlord shall also have the right to perform an audit of the equipment serving the Premises in the form of a facilities condition assessment or similar
report at Tenant’s cost. To the extent such audit recommends corrective action, Tenant shall promptly perform such corrective action as part of its repair and maintenance obligations. 

18.4 Landlord shall not be liable for any failure to make any repairs or to perform any maintenance that is Landlord’s obligation pursuant
to this Lease unless such failure shall persist for an unreasonable time after Tenant provides Landlord with written notice of the need of such repairs or maintenance. Tenant waives its rights under Applicable Laws now or hereafter in effect to make
repairs at Landlord’s expense. 
 18.5 If any excavation shall be made upon land adjacent to or under the Building, or shall be
authorized to be made, Tenant shall afford to the person causing or authorized to cause such excavation, license to enter the Premises for the purpose of performing such work as such person shall deem necessary or desirable to preserve and protect
the Building from injury or damage and to support the same by proper foundations, without any claim for damages or liability against Landlord and without reducing or otherwise affecting Tenant’s obligations under this Lease. 

18.6 Intentionally omitted. 
 18.7
This Article relates to repairs and maintenance arising in the ordinary course of operation of the Building and the Project. In the event of a casualty described in Article 24, Article 24 shall apply in lieu of this Article. In
the event of eminent domain, Article 25 shall apply in lieu of this Article. 
 18.8 Costs incurred by Landlord pursuant to this
Article shall constitute Operating Expenses, subject to the provisions of Article 9. 
 19. Liens. 

19.1 Subject to the immediately succeeding sentence, Tenant shall keep the Premises, the Building and the Project free from any liens arising
from work or services performed, materials furnished to or obligations incurred by Tenant. Tenant further covenants and agrees that any mechanic’s or materialman’s lien filed against the Premises, the Building or the Project for work or
services claimed to have been done for, or materials claimed to have been furnished to, or obligations incurred by Tenant shall be discharged or bonded by Tenant within ten (10) days after Tenant’s receipt of notice of or obtaining actual
knowledge of the filing thereof, at Tenant’s sole cost and expense. 
 19.2 Should Tenant fail to discharge or bond against any lien of
the nature described in Section 19.1, Landlord may, at Landlord’s election, pay such claim or post a statutory lien bond or otherwise provide security to eliminate the lien as a claim against title, and Tenant shall immediately
reimburse Landlord for the costs thereof as Additional Rent. Tenant shall Indemnify the Landlord Indemnitees from and against any Claims arising from any such liens, including any administrative, court or other legal proceedings related to such
liens. 

  
 32 













 19.3 In the event that Tenant leases or finances the acquisition of office equipment,
furnishings or other personal property of a removable nature utilized by Tenant in the operation of Tenant’s business, Tenant warrants that any Uniform Commercial Code financing statement shall, upon its face or by exhibit thereto, indicate
that such financing statement is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address of the Premises, the Building or the Project be furnished on a financing statement without
qualifying language as to applicability of the lien only to removable personal property located in an identified suite leased by Tenant. Should any holder of a financing statement record or place of record a financing statement that appears to
constitute a lien against any interest of Landlord or against equipment that may be located other than within an identified suite leased by Tenant, Tenant shall, within ten (10) days after filing such financing statement, cause (a) a copy
of the lender security agreement or other documents to which the financing statement pertains to be furnished to Landlord to facilitate Landlord’s ability to demonstrate that the lien of such financing statement is not applicable to
Landlord’s interest and (b) Tenant’s lender to amend such financing statement and any other documents of record to clarify that any liens imposed thereby are not applicable to any interest of Landlord in the Premises, the Building or
the Project. 
 20. Estoppel Certificate. Tenant shall, within ten (10) days after receipt of written notice from Landlord, execute, acknowledge
and deliver a statement in writing substantially in the form attached to this Lease as Exhibit I, or on any other form reasonably requested by a current or proposed Lender or encumbrancer or proposed purchaser, (a) certifying that this
Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which rental and other charges are paid in
advance, if any, (b) acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (c) setting forth such further information with
respect to this Lease or the Premises as may be requested thereon. Any such statements may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the Property. Tenant’s failure to deliver any such statement within
such the prescribed time shall, at Landlord’s option, constitute a Default (as defined below) under this Lease, and, in any event, shall be binding upon Tenant that the Lease is in full force and effect and without modification except as may be
represented by Landlord in any certificate prepared by Landlord and delivered to Tenant for execution. 
 21. Hazardous Materials. 

21.1 Tenant shall not cause or permit any Hazardous Materials (as defined below) to be brought upon, kept or used in or about the Premises, the
Building or the Project in violation of Applicable Laws by Tenant or any of its employees, agents, contractors or invitees (collectively with Tenant, each a “Tenant Party”). If (a) Tenant breaches such obligation, (b) the
presence of Hazardous Materials as a result of such a breach results in contamination of the Project, any portion thereof, or any adjacent property, (c) contamination of the Premises otherwise occurs during the Term or any extension or renewal
hereof or holding over hereunder (other than if such contamination results from (i) migration of Hazardous Materials from outside the Premises not arising from the acts or omissions of a Tenant Party or coming from property owned or leased by


  
 33 













 
a Tenant Party or (ii) to the extent such contamination arises directly from Landlord’s gross negligence or willful misconduct) or (d) contamination of the Project occurs as a
result of Hazardous Materials that are placed on or under or are released into the Project by a Tenant Party, then Tenant shall Indemnify the Landlord Indemnitees from and against any and all Claims of any kind or nature, including
(w) diminution in value of the Project or any portion thereof, (x) damages for the loss or restriction on use of rentable or usable space or of any amenity of the Project, (y) damages arising from any adverse impact on marketing of
space in the Project or any portion thereof and (z) sums paid in settlement of Claims that arise before, during or after the Term as a result of such breach or contamination. This Indemnification by Tenant includes costs incurred in connection
with any investigation of site conditions or any clean-up, remedial, removal or restoration work required by any Governmental Authority because of Hazardous Materials present in the air, soil or groundwater above, on, under or about the Project.
Without limiting the foregoing, if the presence of any Hazardous Materials in, on, under or about the Project, any portion thereof or any adjacent property caused or permitted by any Tenant Party results in any contamination of the Project, any
portion thereof or any adjacent property, then Tenant shall promptly take all actions at its sole cost and expense as are necessary to return the Project, any portion thereof or any adjacent property to its respective condition existing prior to the
time of such contamination; provided that Landlord’s written approval of such action shall first be obtained, which approval Landlord shall not unreasonably withhold; and provided, further, that it shall be reasonable for
Landlord to withhold its consent if such actions could have a material adverse long-term or short-term effect on the Project, any portion thereof or any adjacent property. Tenant’s obligations under this Section shall not be affected, reduced
or limited by any limitation on the amount or type of damages, compensation or benefits payable by or for Tenant under workers’ compensation acts, disability benefit acts, employee benefit acts or similar legislation. Landlord hereby agrees to
hold Tenant harmless from and against any and all loss, cost, damage, claim or expense (including legal fees) incurred in connection with or arising out of or relating in any way to the presence of Hazardous Materials at the Property as of the
Execution Date, unless placed on the Property by a Tenant Party. The provisions of the foregoing sentence shall survive the expiration or earlier termination of this Lease. 

21.2 Landlord acknowledges that it is not the intent of this Article to prohibit Tenant from operating its business for the Permitted Use.
Tenant may operate its business according to the custom of Tenant’s industry so long as the use or presence of Hazardous Materials is strictly and properly monitored in accordance with Applicable Laws. As a material inducement to Landlord to
allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord (a) a list identifying each type of Hazardous Material to be present at the Premises that is subject to regulation under any
environmental Applicable Laws in the form of a Tier II form pursuant to Section 312 of the Emergency Planning and Community Right-to-Know Act of 1986 (or any successor statute) or any other form reasonably requested by Landlord, (b) a list
of any and all approvals or permits from Governmental Authorities required in connection with the presence of such Hazardous Material at the Premises and (c) correct and complete copies of (i) notices of violations of Applicable Laws
related to Hazardous Materials and (ii) plans relating to the installation of any storage tanks to be installed in, on, under or about the Project (provided that installation of storage tanks shall only be permitted after Landlord has
given Tenant its written consent to do so, which consent Landlord may withhold in its sole and absolute discretion) and closure plans or any other documents required by any and all Governmental Authorities for any storage tanks installed in, on,
under or about the Project for the closure of any such storage tanks 

  
 34 













 
(collectively, “Hazardous Materials Documents”). Tenant shall deliver to Landlord updated Hazardous Materials Documents, within fourteen (14) days after receipt of a written
request therefor from Landlord, not more often than once per year, unless (m) there are any changes to the Hazardous Materials Documents or (n) Tenant initiates any Alterations or changes its business, in either case in a way that involves
any material increase in the types or amounts of Hazardous Materials, in which case Tenant shall deliver updated Hazardous Materials documents (without Landlord having to request them) before or, if not practicable to do so before, as soon as
reasonably practicable after the occurrence of the events in Subsection 21.2(m) or (n). For each type of Hazardous Material listed, the Hazardous Materials Documents shall include (t) the chemical name, (u) the material state
(e.g., solid, liquid, gas or cryogen), (v) the concentration, (w) the storage amount and storage condition (e.g., in cabinets or not in cabinets), (x) the use amount and use condition (e.g., open use or closed use), (y) the
location (e.g., room number or other identification) and (z) if known, the chemical abstract service number. Notwithstanding anything in this Section to the contrary, Tenant shall not be required to provide Landlord with any documents
containing information of a proprietary nature, unless such documents contain a reference to Hazardous Materials or activities related to Hazardous Materials. Landlord may, at Landlord’s expense, cause the Hazardous Materials Documents to be
reviewed by a person or firm qualified to analyze Hazardous Materials to confirm compliance with the provisions of this Lease and with Applicable Laws. In the event that a review of the Hazardous Materials Documents indicates non-compliance with
this Lease or Applicable Laws, Tenant shall, at its expense, diligently take steps to bring its storage and use of Hazardous Materials into compliance. Notwithstanding anything in this Lease to the contrary or Landlord’s review into
Tenant’s Hazardous Materials Documents or use or disposal of hazardous materials, however, Landlord shall not have and expressly disclaims any liability related to Tenant’s or other tenants’ use or disposal of Hazardous Materials, it
being acknowledged by Tenant that Tenant is best suited to evaluate the safety and efficacy of its Hazardous Materials usage and procedures. 

21.3 Tenant represents and warrants to Landlord that it is not nor has it been, in connection with the use, disposal or storage of Hazardous
Materials, (a) subject to a material enforcement order issued by any Governmental Authority or (b) required to take any remedial action. 

21.4 At any time, and from time to time, prior to the expiration of the Term, Landlord shall have the right to conduct appropriate tests of the
Project or any portion thereof to demonstrate that Hazardous Materials are present or that contamination has occurred due to the acts or omissions of a Tenant Party. Tenant shall pay all reasonable costs of such tests if such tests reveal that
Hazardous Materials exist at the Project in violation of Tenant’s obligations under this Lease. 
 21.5 If underground or other storage
tanks storing Hazardous Materials installed or utilized by Tenant are located on the Premises, or are hereafter placed on the Premises by Tenant (or by any other party, if such storage tanks are utilized by Tenant), then Tenant shall monitor the
storage tanks, maintain appropriate records, implement reporting procedures, properly close any underground storage tanks, and take or cause to be taken all other steps necessary or required under the Applicable Laws. Tenant shall have no
responsibility or liability for underground or other storage tanks installed by anyone other than Tenant unless Tenant utilizes such tanks, in which case Tenant’s responsibility for such tanks shall be as set forth in this Section. 

  
 35 













 21.6 Tenant shall promptly report to Landlord any actual or suspected presence of mold or
water intrusion at the Premises. 
 21.7 Tenant’s obligations under this Article shall survive the expiration or earlier termination of
the Lease. During any period of time needed by Tenant or Landlord after the termination of this Lease to complete the removal from the Premises of any such Hazardous Materials, Tenant shall be deemed a holdover tenant and subject to the provisions
of Article 27. 
 21.8 As used herein, the term “Hazardous Material” means any toxic, explosive, corrosive,
flammable, infectious, radioactive, carcinogenic, mutagenic or otherwise hazardous substance, material or waste that is or becomes regulated by Applicable Laws or any Governmental Authority. 

21.9 Notwithstanding anything to the contrary in this Lease, Landlord shall have sole control over the equitable allocation of fire control
areas (as defined in the Uniform Building Code as adopted by the city or municipality(ies) in which the Project is located (the “UBC”)) within the Project for the storage of Hazardous Materials. Notwithstanding anything to the
contrary in this Lease, the quantity of Hazardous Materials allowed by this Section is specific to Tenant and shall not run with the Lease in the event of a Transfer (as defined in Article 29). In the event of a Transfer, if the use of
Hazardous Materials by such new tenant (“New Tenant”) is such that New Tenant utilizes fire control areas in the Project in excess of New Tenant’s Pro Rata Share of the Building or the Project, as applicable, then New Tenant
shall, at its sole cost and expense and upon Landlord’s written request, establish and maintain a separate area of the Premises classified by the UBC as an “H” occupancy area for the use and storage of Hazardous Materials, or take
such other action as is necessary to ensure that its share of the fire control areas of the Building and the Project is not greater than New Tenant’s Pro Rata Share of the Building or the Project, as applicable. Notwithstanding anything in this
Lease to the contrary, Landlord shall not have and expressly disclaims any liability related to Tenant’s or other tenants’ use or disposal of fire control areas, it being acknowledged by Tenant that Tenant and other tenants are best suited
to evaluate the safety and efficacy of its Hazardous Materials usage and procedures. 
 22. Odors and Exhaust. Tenant acknowledges that Landlord
would not enter into this Lease with Tenant unless Tenant assured Landlord that under no circumstances will any other occupants of the Building or the Project (including persons legally present in any outdoor areas of the Project) be subjected to
odors or fumes (whether or not noxious), and that the Building and the Project will not be damaged by any exhaust, in each case from Tenant’s operations, including in Tenant’s vivarium. Landlord and Tenant therefore agree as follows: 

22.1 Tenant shall not cause or permit (or conduct any activities that would cause) any release of any odors or fumes of any kind from the
Premises. 
 22.2 If the Building has a ventilation system that, in Landlord’s judgment, is adequate, suitable, and appropriate to vent
the Premises in a manner that does not release odors affecting any indoor or outdoor part of the Project, Tenant shall vent the Premises through such system. If Landlord at any time determines that any existing ventilation system is inadequate, or
if no ventilation system exists, Tenant shall in compliance with Applicable Laws vent all fumes and odors from the Premises (and remove odors from Tenant’s exhaust stream) as Landlord requires. 


  
 36 













 
The placement and configuration of all ventilation exhaust pipes, louvers and other equipment shall be subject to Landlord’s approval. Tenant acknowledges Landlord’s legitimate desire
to maintain the Project (indoor and outdoor areas) in an odor-free manner, and Landlord may require Tenant to abate and remove all odors in a manner that goes beyond the requirements of Applicable Laws. 

22.3 Tenant shall, at Tenant’s sole cost and expense, provide odor eliminators and other devices (such as filters, air cleaners, scrubbers
and whatever other equipment may in Landlord’s judgment be necessary or appropriate from time to time) to completely remove, eliminate and abate any odors, fumes or other substances in Tenant’s exhaust stream that, in Landlord’s
judgment, emanate from Tenant’s Premises. Any work Tenant performs under this Section shall constitute Alterations. 
 22.4
Tenant’s responsibility to remove, eliminate and abate odors, fumes and exhaust shall continue throughout the Term. Landlord’s approval of the Tenant Improvements shall not preclude Landlord from requiring additional measures to eliminate
odors, fumes and other adverse impacts of Tenant’s exhaust stream (as Landlord may designate in Landlord’s discretion). Tenant shall install additional equipment as Landlord requires from time to time under the preceding sentence. Such
installations shall constitute Alterations. 
 22.5 If Tenant fails to install satisfactory odor control equipment within ten
(10) business days after Landlord’s demand made at any time, then Landlord may, without limiting Landlord’s other rights and remedies, require Tenant to cease and suspend any operations in the Premises that, in Landlord’s
determination, cause odors, fumes or exhaust. For example, if Landlord determines that Tenant’s production of a certain type of product causes odors, fumes or exhaust, and Tenant does not install satisfactory odor control equipment within ten
(10) business days after Landlord’s request, then Landlord may require Tenant to stop producing such type of product in the Premises unless and until Tenant has installed odor control equipment satisfactory to Landlord. 

23. Insurance. 
 23.1 Landlord shall
maintain insurance for the Building and the Project in amounts equal to full replacement cost (exclusive of the costs of excavation, foundations and footings, engineering costs or such other costs to the extent the same are not incurred in the event
of a rebuild and without reference to depreciation taken by Landlord upon its books or tax returns), providing protection against any peril generally included within the classification “Fire and Extended Coverage,” together with insurance
against sprinkler damage (if applicable), vandalism and malicious mischief. Landlord, subject to availability thereof, shall further insure, if Landlord deems it appropriate, coverage against flood, environmental hazard, earthquake, loss or failure
of building equipment, rental loss during the period of repairs or rebuilding, Workers’ Compensation insurance and fidelity bonds for employees employed to perform services. Notwithstanding the foregoing, Landlord may, but shall not be deemed
required to, provide insurance for any improvements installed by Tenant or that are in addition to the standard improvements customarily furnished by Landlord, without regard to whether or not such are made a part of or are affixed to the Building.


  
 37 













 23.2 In addition, Landlord shall carry Commercial General Liability insurance with limits of
not less than Five Million Dollars ($5,000,000) per occurrence/general aggregate for bodily injury (including death), or property damage with respect to the Project, which limit may be met by use of excess and/or umbrella liability insurance;
provided that such coverage is at least as broad as the primary coverage required herein. 
 23.3 Tenant shall, at its own cost and
expense, procure and maintain during the Term the following insurance for the benefit of Tenant and Landlord (as their interests may appear) with insurers financially acceptable and lawfully authorized to do business in the state where the Premises
are located: 
 (a) Commercial General Liability insurance on a broad-based occurrence coverage form, with coverages including but not
limited to bodily injury (including death), property damage (including loss of use resulting therefrom), premises/operations, personal & advertising injury, and contractual liability with limits of liability of not less than $2,000,000 for
bodily injury and property damage per occurrence, $4,000,000 general aggregate, which limits may be met by use of excess and/or umbrella liability insurance; provided that such coverage is at least as broad as the primary coverages required
herein. 
 (b) Commercial Automobile Liability insurance covering liability arising from the use or operation of any auto on behalf of Tenant
or invited by Tenant (including those owned, hired, rented, leased, borrowed, scheduled or non-owned). Coverage shall be on a broad-based occurrence form in an amount not less than $2,000,000 combined single limit per accident for bodily injury and
property damage. Such coverage shall apply to all vehicles and persons, whether accessing the property with active or passive consent. 
 (c)
Commercial Property insurance covering property damage to the full replacement cost value and business interruption. Covered property shall include all tenant improvements in the Premises (to the extent not insured by Landlord pursuant to
Section 23.1) and Tenant’s Property including personal property, furniture, fixtures, machinery, equipment, stock, inventory and improvements and betterments, which may be owned by Tenant or Landlord and required to be insured
hereunder, or which may be leased, rented, borrowed or in the care custody or control of Tenant, or Tenant’s agents, employees or subcontractors. Such insurance, with respect only to all Tenant Improvements, Alterations or other work performed
on the Premises by Tenant (collectively, “Tenant Work”), shall name Landlord and Landlord’s current and future mortgagees as loss payees as their interests may appear. Such insurance shall be written on an “all risk”
of physical loss or damage basis including the perils of fire, extended coverage, electrical injury, mechanical breakdown, windstorm, vandalism, malicious mischief, sprinkler leakage, back-up of sewers or drains, flood, earthquake, terrorism and
such other risks Landlord may from time to time designate, for the full replacement cost value of the covered items with an agreed amount endorsement with no co-insurance. Business interruption coverage shall have limits sufficient to cover
Tenant’s lost profits and necessary continuing expenses, including rents due Landlord under the Lease. The minimum period of indemnity for business interruption coverage shall be twelve (12) months. 

  
 38 













 (d) Workers’ Compensation in compliance with all Applicable Laws or as may be available
on a voluntary basis. Employer’s Liability must be at least in the amount of $1,000,000 for bodily injury by accident for each employee, $1,000,000 for bodily injury by disease for each employee, and $1,000,000 bodily injury by disease for
policy limit. 
 (e) Medical malpractice insurance at limits of not less than $1,000,000 each claim during such periods, if any, that Tenant
engages in the practice of medicine or clinical trials involving human beings at the Premises. 
 (f) Pollution Legal Liability insurance is
required if Tenant stores, handles, generates or treats Hazardous Materials, as determined solely by Landlord, on or about the Premises. Such coverage shall include bodily injury, sickness, disease, death or mental anguish or shock sustained by any
person; property damage including physical injury to or destruction of tangible property including the resulting loss of use thereof, clean-up costs, and the loss of use of tangible property that has not been physically injured or destroyed; and
defense costs, charges and expenses incurred in the investigation, adjustment or defense of claims for such compensatory damages. Coverage shall apply to both sudden and non-sudden pollution conditions including the discharge, dispersal, release or
escape of smoke, vapors, soot, fumes, acids, alkalis, toxic chemicals, liquids or gases, waste materials or other irritants, contaminants or pollutants into or upon land, the atmosphere or any watercourse or body of water. Claims-made coverage is
permitted, provided the policy retroactive date is continuously maintained prior to the commencement date of this agreement, and coverage is continuously maintained during all periods in which Tenant occupies the Premises. Coverage shall be
maintained with limits of not less than $1,000,000 per incident with a $2,000,000 policy aggregate and for a period of two (2) years thereafter. 

(g) During all construction by Tenant at the Premises, with respect to tenant improvements being constructed (including the Tenant Improvements
and any Alterations, insurance required in Exhibit B-1 must be in place. 
 23.4 The insurance required of Tenant by this Article
shall be with companies at all times having a current rating of not less than A- and financial category rating of at least Class VII in “A.M. Best’s Insurance Guide” current edition. Tenant shall obtain for Landlord from the insurance
companies/broker or cause the insurance companies/broker to furnish certificates of insurance evidencing all coverages required herein to Landlord including copies of any endorsements. No such policy shall be cancelable or subject to reduction of
coverage or other modification or cancellation except after thirty (30) days’ prior written notice to Landlord from Tenant or its insurers (except in the event of non-payment of premium, in which case ten (10) days’ written
notice shall be given). All such policies shall be written as primary policies, not contributing with and not in excess of the coverage that Landlord may carry. Tenant’s required policies shall contain severability of interests clauses stating
that, except with respect to limits of insurance, coverage shall apply separately to each insured or additional insured. Tenant shall, on the date of expiration of such policies, furnish Landlord with renewal certificates of insurance or binders.
Tenant agrees that if Tenant does not take out and maintain such insurance, Landlord may (but shall not be required to) procure such insurance on Tenant’s behalf and at its cost to be paid by Tenant as Additional Rent. Commercial General
Liability, Commercial Automobile Liability, Umbrella Liability and Pollution Legal Liability insurance as required above shall name the Landlord Parties as additional insureds as respects liability arising from work or operations performed by or on
behalf of Tenant, Tenant’s use or occupancy of Premises, and ownership, 

  
 39 













 
maintenance or use of vehicles by or on behalf of Tenant. Tenant must disclose any self-insurance, including self-insurance retentions, to Landlord in writing in advance, which shall be subject
to Landlord’s prior written approval in its sole discretion. If Tenant self-insures with Landlord’s prior written approval, Tenant is itself acting as though it were providing the insurance required under the provisions of this Lease, and
Tenant shall pay those amounts due in lieu of insurance proceeds that would have been covered and payable if the insurance policies had been carried for such self-insured coverages, which amounts shall be treated as insurance proceeds for all
purposes under this Lease. 
 23.5 In each instance where insurance is to name the Landlord Parties as additional insureds, Tenant shall,
upon Landlord’s written request, also designate and furnish certificates evidencing the Landlord Parties as additional insureds to (a) any Lender of Landlord holding a security interest in the Building or the Project, (b) the landlord
under any lease whereunder Landlord is a tenant of the real property upon which the Building is located if the interest of Landlord is or shall become that of a tenant under a ground lease rather than that of a fee owner and (c) any management
company retained by Landlord to manage the Project. 
 23.6 Tenant assumes the risk of damage to any fixtures, goods, inventory, merchandise,
equipment and leasehold improvements, and Landlord shall not be liable for injury to Tenant’s business or any loss of income therefrom, relative to such damage, all as more particularly set forth within this Lease. Tenant shall, at
Tenant’s sole cost and expense, carry such insurance as Tenant desires for Tenant’s protection with respect to personal property of Tenant or business interruption. 

23.7 Except in cases of gross negligence or willful misconduct, each of Tenant and Landlord, on behalf of themselves and their respective
insurers, hereby waive any and all rights of recovery or subrogation against the Landlord Parties with respect to any loss, damage, claims, suits or demands, howsoever caused, that are covered, or should have been covered, by valid and collectible
workers’ compensation, employer’s liability insurance and other liability insurance required to obtained and carried by the parties pursuant to this Article, including any deductibles or self-insurance maintained thereunder. If necessary,
Tenant and Landlord agree to endorse the required workers’ compensation, employer’s liability and other liability insurance policies to permit waivers of subrogation as required hereunder and hold harmless and indemnify the Landlord
Parties and Tenant Parties, as applicable, for any loss or expense incurred as a result of a failure to obtain such waivers of subrogation from insurers. Such waivers shall continue so long as Tenant’s and Landlord’s insurers so permit.
Any termination of such a waiver shall be by written notice to Landlord or Tenant, as applicable, containing a description of the circumstances hereinafter set forth in this Section. Tenant, upon obtaining the policies of workers’ compensation,
employer’s liability and other liability insurance required or permitted under this Lease, shall give notice to its insurance carriers that the foregoing waiver of subrogation is contained in this Lease. If such policies shall not be obtainable
with such waiver or shall be so obtainable only at a premium over that chargeable without such waiver, then Tenant shall notify Landlord of such conditions. 

23.8 Landlord may require insurance policy limits required under this Lease to be raised to conform with requirements of Landlord’s Lender
or to bring coverage limits to levels then being required of new tenants within the Project. 

  
 40 













 23.9 In addition to other insurance required by this Lease to be carried by Tenant, if
Tenant sells, merchandises, transfers, gives away or exchanges alcoholic beverages in, upon or from any part of the Premises, then Tenant shall, at Tenant’s sole cost and expense, purchase and maintain in full force and effect during the Term
dram shop insurance in form and substance satisfactory to Landlord, with total limits of liability for bodily injury, loss of means of support and property damage for each occurrence in an amount and with a carrier reasonably acceptable to Landlord,
and otherwise in compliance with the general provisions of this Article governing the provision of insurance by Tenant. Such policy shall name the Landlord Parties as additional insureds against any liability by virtue of Applicable Laws concerning
the use, sale or giving away of alcoholic beverages. If at any time such insurance is for any reason not in force, then during all and any such times no selling, merchandising, transferring, giving away or exchanging of alcoholic beverages shall be
conducted by Tenant in, upon or from any part of the Premises. 
 23.10 Any costs incurred by Landlord pursuant to this Article shall
constitute a portion of Operating Expenses, subject to Article 9. 
 24. Damage or Destruction. 

24.1 In the event of a partial destruction of (a) the Premises, (b) the Building, (c) the Common Area or (d) the Project
((a)-(d) collectively, the “Affected Areas”) by fire or other perils covered by extended coverage insurance not exceeding twenty-five percent (25%) of the full insurable value thereof, and provided that (w) the
damage thereto is such that the Affected Areas may be repaired, reconstructed or restored within a period of twelve (12) months from the date of the happening of such casualty, (x) Landlord shall receive insurance proceeds from its insurer
or Lender sufficient to cover the cost of such repairs, reconstruction and restoration (except for any deductible amount provided by Landlord’s policy, which deductible amount, if paid by Landlord, shall constitute an Operating Expense),
(y) the repair, reconstruction or restoration of the Affected Areas is permitted by all applicable Loan Documents or otherwise consented to by any and all Lenders whose consent is required thereunder and (z) such casualty was not
intentionally caused by a Tenant Party, then Landlord shall commence and proceed diligently with the work of repair, reconstruction and restoration of the Affected Areas and this Lease shall continue in full force and effect. 

24.2 In the event of any damage to or destruction of the Building or the Project other than as described in Section 24.1, Landlord
may elect to repair, reconstruct and restore the Building or the Project, as applicable, in which case this Lease shall continue in full force and effect. If Landlord elects not to repair, reconstruct and restore the Building or the Project, as
applicable, then this Lease shall terminate as of the date of such damage or destruction. In the event of any damage or destruction (regardless of whether such damage is governed by Section 24.1 or this Section), if (a) in
Landlord’s determination as set forth in the Damage Repair Estimate (as defined below), the Affected Areas cannot be repaired, reconstructed or restored within fifteen (15) months after the date of such casualty, or (b) subject to
Section 24.6, the Affected Areas are not actually repaired, reconstructed and restored within fifteen (15) months after the date of such casualty, then Tenant shall have the right to terminate this Lease, effective as of the date of
such damage or destruction, by delivering to Landlord its written notice of termination (a “Termination Notice”) (y) with respect to Subsection 24.2(a), no later than fifteen (15) days after Landlord delivers to
Tenant Landlord’s Damage Repair Estimate and (z) with respect to Subsection 24.2(b), no later 

  
 41 













 
than fifteen (15) days after such eighteen (18) month period (as the same may be extended pursuant to Section 24.6) expires. If Tenant provides Landlord with a Termination
Notice pursuant to Subsection 24.2(z), Landlord shall have an additional thirty (30) days after receipt of such Termination Notice to complete the repair, reconstruction and restoration. If Landlord does not complete such repair,
reconstruction and restoration within such thirty (30) day period, then Tenant may terminate this Lease by giving Landlord written notice within two (2) business days after the expiration of such thirty (30) day period. If Landlord
does complete such repair, reconstruction and restoration within such thirty (30) day period, then this Lease shall continue in full force and effect 

24.3 As soon as reasonably practicable, but in any event within sixty (60) days following the date of damage or destruction, Landlord
shall notify Tenant of Landlord’s good faith estimate of the period of time in which the repairs, reconstruction and restoration will be completed (the “Damage Repair Estimate”), which estimate shall be based upon the opinion
of a contractor reasonably selected by Landlord and experienced in comparable repair, reconstruction and restoration of similar buildings. Additionally, Landlord shall give written notice to Tenant within sixty (60) days following the date of
damage or destruction of its election not to repair, reconstruct or restore the Building or the Project, as applicable. 
 24.4 Upon any
termination of this Lease under any of the provisions of this Article, the parties shall be released thereby without further obligation to the other from the date possession of the Premises is surrendered to Landlord, except with regard to
(a) items occurring prior to the damage or destruction and (b) provisions of this Lease that, by their express terms, survive the expiration or earlier termination hereof. 

24.5 In the event of repair, reconstruction and restoration as provided in this Article, all Rent to be paid by Tenant under this Lease shall
be abated proportionately based on the extent to which Tenant’s use of the Premises is impaired during the period of such repair, reconstruction or restoration, unless Landlord provides Tenant with other space during the period of repair,
reconstruction and restoration that, in Tenant’s reasonable opinion, is suitable for the temporary conduct of Tenant’s business; provided, however, that the amount of such abatement shall be reduced by the amount of Rent that
is received by Tenant as part of the business interruption or loss of rental income with respect to the Premises from the proceeds of business interruption or loss of rental income insurance. For the avoidance of doubt, to the extent any such
repair, reconstruction and restoration provided in this Article relates to portions of the Building that Landlord is obligated to maintain pursuant to the terms and conditions of this Lease, then Landlord’s business interruption policy shall be
primary and in the event any such repair, reconstruction and restoration provided in this Article relates to portions of the Premises or Building that Tenant is obligated to maintain pursuant to the terms and conditions of this Lease, then
Tenant’s business interruption policy shall be primary. 
 24.6 Notwithstanding anything to the contrary contained in this Article,
(a) Landlord shall not be required to repair, reconstruct or restore any damage or destruction to the extent that Landlord is prohibited from doing so by any applicable Loan Document or any Lender whose consent is required thereunder withholds
its consent, and (b) should Landlord be delayed or prevented from completing the repair, reconstruction or restoration of the damage or destruction to the Premises after the occurrence of such damage or destruction by Force Majeure (as defined
below) or delays caused by a Lender or Tenant Party, then the time for Landlord to commence or complete repairs, reconstruction and restoration shall be extended on a day-for-day basis; provided, however, that, at Landlord’s election,
Landlord shall be relieved of its obligation to make such repairs, reconstruction and restoration. 

  
 42 













 24.7 If Landlord is obligated to or elects to repair, reconstruct or restore as herein
provided, then Landlord shall be obligated to make such repairs, reconstruction or restoration only with regard to (a) those portions of the Premises that were originally provided at Landlord’s expense and (b) the Common Area portion
of the Affected Areas. The repairs, reconstruction or restoration of improvements not originally provided by Landlord or at Landlord’s expense shall be the obligation of Tenant. In the event Tenant has elected to upgrade certain improvements
from the Building Standard, Landlord shall, upon the need for replacement due to an insured loss, provide only the Building Standard, unless Tenant again elects to upgrade such improvements and pay any incremental costs related thereto, except to
the extent that excess insurance proceeds, if received, are adequate to provide such upgrades, in addition to providing for basic repairs, reconstruction and restoration of the Premises, the Building and the Project. 

24.8 Notwithstanding anything to the contrary contained in this Article, Landlord shall not have any obligation whatsoever to repair,
reconstruct or restore the Premises if the damage resulting from any casualty covered under this Article occurs during the last twelve (12) months of the Term or any extension thereof, or to the extent that insurance proceeds are not available
therefor. 
 24.9 Landlord’s obligation, should it elect or be obligated to repair, reconstruct or restore, shall be limited to the
Affected Areas, and shall be conditioned upon Landlord receiving any permits or authorizations required by Applicable Laws. Tenant shall, at its expense, replace or fully repair all of Tenant’s personal property and any Alterations installed by
Tenant existing at the time of such damage or destruction. If Affected Areas are to be repaired, reconstructed or restored in accordance with the foregoing, Landlord shall make available to Tenant any portion of insurance proceeds it receives that
are allocable to the Alterations constructed by Tenant pursuant to this Lease; provided Tenant is not then in default under this Lease, and subject to the requirements of any Lender of Landlord. 

24.10 This Article sets forth the terms and conditions upon which this Lease may terminate in the event of any damage or destruction.
Accordingly, the parties hereby waive the provisions of any Applicable Laws (and any successor statutes) permitting the parties to terminate this Lease as a result of any damage or destruction. 

25. Eminent Domain. 
 25.1 In the event
(a) the whole of all Affected Areas or (b) such part thereof as shall substantially interfere with Tenant’s use and occupancy of the Premises for the Permitted Use shall be taken for any public or quasi-public purpose by any lawful
power or authority by exercise of the right of appropriation, condemnation or eminent domain, or sold to prevent such taking, Tenant or Landlord may terminate this Lease effective as of the date possession is required to be surrendered to such
authority, except with regard to (y) items occurring prior to the taking and (z) provisions of this Lease that, by their express terms, survive the expiration or earlier termination hereof. 

  
 43 













 25.2 In the event of a partial taking of (a) the Building or the Project or
(b) drives, walkways or parking areas serving the Building or the Project for any public or quasi-public purpose by any lawful power or authority by exercise of right of appropriation, condemnation, or eminent domain, or sold to prevent such
taking, then, without regard to whether any portion of the Premises occupied by Tenant was so taken, Landlord may elect to terminate this Lease (except with regard to (a) items occurring prior to the taking and (b) provisions of this Lease
that, by their express terms, survive the expiration or earlier termination hereof) as of such taking if such taking is, in Landlord’s sole opinion, of a material nature such as to make it uneconomical to continue use of the unappropriated
portion for purposes of renting office or laboratory space. 
 25.3 Tenant shall be entitled to any award that is specifically awarded as
compensation for (a) the taking of Tenant’s personal property that was installed at Tenant’s expense and (b) the costs of Tenant moving to a new location. Except as set forth in the previous sentence, any award for such taking
shall be the property of Landlord. 
 25.4 If, upon any taking of the nature described in this Article, this Lease continues in effect, then
Landlord shall promptly proceed to restore the Affected Areas to substantially their same condition prior to such partial taking. To the extent such restoration is infeasible, as determined by Landlord in its sole and absolute discretion, the Rent
shall be decreased proportionately to reflect the loss of any portion of the Premises no longer available to Tenant. Notwithstanding anything to the contrary contained in this Article, Landlord shall not be required to restore the Affected Areas to
the extent that Landlord is prohibited from doing so by any applicable Loan Document or any Lender whose consent is required thereunder withholds its consent. 

25.5 This Article sets forth the terms and conditions upon which this Lease may terminate in the event of any taking. Accordingly, the parties
hereby waive the provisions of any Applicable Laws permitting the parties to terminate this Lease as a result of any taking. 
 26. Surrender. 

26.1 At least thirty (30) days prior to Tenant’s surrender of possession of any part of the Premises, Tenant shall provide Landlord
with a facility decommissioning and Hazardous Materials closure plan for the Premises (“Exit Survey”) prepared by an independent third party state-certified professional with appropriate expertise, which Exit Survey must be
reasonably acceptable to Landlord. The Exit Survey shall comply with the American National Standards Institute’s Laboratory Decommissioning guidelines (ANSI/AIHA Z9.11-2008) or any successor standards published by ANSI or any successor
organization (or, if ANSI and its successors no longer exist, a similar entity publishing similar standards). In addition, at least ten (10) days prior to Tenant’s surrender of possession of any part of the Premises, Tenant shall
(a) provide Landlord with written evidence of all appropriate governmental releases obtained by Tenant in accordance with Applicable Laws, including laws pertaining to the surrender of the Premises, (b) place Laboratory Equipment
Decontamination Forms on all decommissioned equipment to assure safe occupancy by future users and (c) conduct a site inspection with Landlord. In addition, Tenant agrees to remain responsible after the surrender of the Premises for the
remediation of any recognized environmental conditions set forth in the Exit Survey and comply with any recommendations set forth in the Exit Survey. Tenant’s obligations under this Section shall survive the expiration or earlier termination of
the Lease. 

  
 44 













 26.2 No surrender of possession of any part of the Premises shall release Tenant from any of
its obligations hereunder, unless such surrender is accepted in writing by Landlord. 
 26.3 The voluntary or other surrender of this Lease
by Tenant shall not effect a merger with Landlord’s fee title or leasehold interest in the Premises, the Building, the Property or the Project, unless Landlord consents in writing, and shall, at Landlord’s option, operate as an assignment
to Landlord of any or all subleases. 
 26.4 The voluntary or other surrender of any ground or other underlying lease that now exists or may
hereafter be executed affecting the Building or the Project, or a mutual cancellation thereof or of Landlord’s interest therein by Landlord and its lessor shall not effect a merger with Landlord’s fee title or leasehold interest in the
Premises, the Building or the Property and shall, at the option of the successor to Landlord’s interest in the Building or the Project, as applicable, operate as an assignment of this Lease. 

27. Holding Over. 
 27.1 If, with
Landlord’s prior written consent, Tenant holds possession of all or any part of the Premises after the Term, Tenant shall become a tenant from month to month after the expiration or earlier termination of the Term, and in such case Tenant shall
continue to pay (a) Base Rent in accordance with Article 7, as adjusted in accordance with Article 8, and (b) any amounts for which Tenant would otherwise be liable under this Lease if the Lease were still in effect,
including payments for Tenant’s Adjusted Share of Operating Expenses, and all other Additional Rent. Any such month-to-month tenancy shall be subject to every other term, covenant and agreement contained herein. 

27.2 Notwithstanding the foregoing, if Tenant remains in possession of the Premises after the expiration or earlier termination of the Term
without Landlord’s prior written consent, (a) Tenant shall become a tenant at sufferance subject to the terms and conditions of this Lease, except that the monthly rent shall be equal to one hundred fifty percent (150%) of the Base
Rent in effect during the last thirty (30) days of the Term, plus all other Additional Rent and (b) Tenant shall be liable to Landlord for any and all damages suffered by Landlord as a result of such holdover, including any lost rent or
consequential, special and indirect damages (in each case, regardless of whether such damages are foreseeable). 
 27.3 Acceptance by
Landlord of Rent after the expiration or earlier termination of the Term shall not result in an extension, renewal or reinstatement of this Lease. 

27.4 The foregoing provisions of this Article are in addition to and do not affect Landlord’s right of reentry or any other rights of
Landlord hereunder or as otherwise provided by Applicable Laws. 

  
 45 













 27.5 The provisions of this Article shall survive the expiration or earlier termination of
this Lease. 
 28. Indemnification and Exculpation. 

28.1 Tenant agrees to Indemnify the Landlord Indemnitees from and against any and all Claims of any kind or nature, real or alleged, arising
from (a) injury to or death of any person or damage to any property occurring within or about the Premises, the Building, the Property or the Project, arising directly or indirectly out of (i) the presence at or use or occupancy of the
Premises or Project by a Tenant Party or (ii) an act or omission on the part of any Tenant Party, (b) a breach or default by Tenant in the performance of any of its obligations hereunder (including any Claim asserted by a Lender against
any Landlord Indemnitees under any Loan Document as a direct result of such breach or default by Tenant) or (c) injury to or death of persons or damage to or loss of any property, real or alleged, arising from the serving of alcoholic beverages
at the Premises or Project, including liability under any dram shop law, host liquor law or similar Applicable Law, except to the extent arising directly from Landlord’s negligence or willful misconduct. Tenant’s obligations under this
Section shall not be affected, reduced or limited by any limitation on the amount or type of damages, compensation or benefits payable by or for Tenant under workers’ compensation acts, disability benefit acts, employee benefit acts or similar
legislation. Tenant’s obligations under this Section shall survive the expiration or earlier termination of this Lease. Subject to Sections 28.2 and 31.13, Landlord agrees to Indemnify the Tenant Parties from and against any and
all Claims arising from injury to or death of any person or damage to or loss of any physical property occurring within or about the Premises, the Building, the Property or the Project to the extent arising directly from Landlord’s gross
negligence or willful misconduct. 
 28.2 Notwithstanding anything in this Lease to the contrary, Landlord shall not be liable to Tenant for
and Tenant assumes all risk of (a) damage or losses arising from fire, electrical malfunction, gas explosion or water damage of any type (including broken water lines, malfunctioning fire sprinkler systems, roof leaks or stoppages of lines),
unless any such loss is due to Landlord’s willful disregard of written notice by Tenant of need for a repair that Landlord is responsible to make for an unreasonable period of time, and (b) damage to personal property or scientific
research, including loss of records kept by Tenant within the Premises (in each case, regardless of whether such damages are foreseeable). Tenant further waives any claim for injury to Tenant’s business or loss of income relating to any such
damage or destruction of personal property as described in this Section. Notwithstanding anything in the foregoing or this Lease to the contrary, except (x) as otherwise provided herein (including Section 27.2), (y) as may be
provided by Applicable Laws or (z) in the event of Tenant’s breach of Article 21 or Section 26.1, in no event shall Landlord or Tenant be liable to the other for any consequential, special or indirect damages arising
from this Lease, including lost profits (provided that this Subsection 28.2(z) shall not limit Tenant’s liability for Base Rent or Additional Rent pursuant to this Lease). 

28.3 Landlord shall not be liable for any damages arising from any act, omission or neglect of any other tenant in the Building or the Project,
or of any other third party. 

  
 46 













 28.4 Tenant acknowledges that security devices and services, if any, while intended to deter
crime, may not in given instances prevent theft or other criminal acts. Landlord shall not be liable for injuries or losses arising from criminal acts of third parties, and Tenant assumes the risk that any security device or service may malfunction
or otherwise be circumvented by a criminal, or that Landlord may decide (in its sole and absolute discretion) not to monitor any installed security devices. If Tenant desires protection against such criminal acts, then Tenant shall, at Tenant’s
sole cost and expense, obtain appropriate insurance coverage. Tenant’s security programs and equipment for the Premises shall be coordinated with Landlord and subject to Landlord’s reasonable approval. 

28.5 The provisions of this Article shall survive the expiration or earlier termination of this Lease. 

29. Assignment or Subletting. 
 29.1
Except as hereinafter expressly permitted, none of the following (each, a “Transfer”), either voluntarily or by operation of Applicable Laws, shall be directly or indirectly performed without Landlord’s prior written consent,
not to be unreasonably withheld, conditioned or delayed: (a) Tenant selling, hypothecating, assigning, pledging, encumbering or otherwise transferring its interest in this Lease or subletting all or a portion of the Premises, (b) a
controlling interest in Tenant being sold, assigned or otherwise transferred (other than as a result of shares in Tenant being sold on a public stock exchange) or (c) the sale of all or substantially of Tenant’s assets. For purposes of the
preceding sentence, “control” means (f) owning (directly or indirectly) more than fifty percent (50%) of the stock or other equity interests of another person or (g) possessing, directly or indirectly, the power to direct or
cause the direction of the management and policies of such person. Notwithstanding the foregoing, Tenant shall have the right to Transfer, without Landlord’s prior written consent, Tenant’s interest in this Lease or the Premises or any
part thereof to (x) any person that as of the date of determination and at all times thereafter directly, or indirectly through one or more intermediaries, controls, is controlled by or is under common control with Tenant
(“Tenant’s Affiliate”) or (y) succeeds to the interest of Tenant hereunder by virtue of a merger, consolidation, or sale of all or substantially all of the assets of Tenant or a controlling interest in Tenant (a
“Permitted Successor”); provided that, subject to applicable confidentiality requirements, Tenant shall notify Landlord in writing at least thirty (30) days prior to the effectiveness of such Transfer to Tenant’s
Affiliate or a Permitted Successor (an “Exempt Transfer”) and otherwise comply with the requirements of this Lease regarding such Transfer; and provided, further, that the person that will be the tenant under this Lease after
the Exempt Transfer has a tangible net worth (as of both the day immediately prior to and the day immediately after the Exempt Transfer) that is equal to or greater than the net worth (as of both the Execution Date and the date of the Exempt
Transfer) of the transferring Tenant. For purposes of the immediately preceding sentence, “control” requires both (m) owning (directly or indirectly) more than fifty percent (50%) of the stock or other equity interests of another
person and (n) possessing, directly or indirectly, the power to direct or cause the direction of the management and policies of such person. In no event shall Tenant perform a Transfer (other than an Exempt Transfer) to or with an entity that
is a tenant at the Project or that is in discussions or negotiations with Landlord or an affiliate of Landlord to lease premises at the Project or a property owned by Landlord or an affiliate of Landlord. 

  
 47 













 29.2 In the event Tenant desires to effect a Transfer, then, at least thirty (30) but
not more than one hundred twenty (120) days prior to the date when Tenant desires the Transfer to be effective (the “Transfer Date”), Tenant shall provide written notice to Landlord (the “Transfer Notice”)
containing information (including references) concerning the character of the proposed transferee, assignee or sublessee; the Transfer Date; the most recent unconsolidated financial statements of Tenant and of the proposed transferee, assignee or
sublessee satisfying the requirements of Section 40.2 (“Required Financials”); any ownership or commercial relationship between Tenant and the proposed transferee, assignee or sublessee; copies of Hazardous Materials Documents for the
proposed transferee, assignee or sublessee; and the consideration and all other material terms and conditions of the proposed Transfer, all in such detail as Landlord shall reasonably require. 

29.3 Landlord, in determining whether consent should be given to a proposed Transfer, may give consideration to such factors as Landlord
reasonably deems material, including (a) the financial strength of Tenant and of such transferee, assignee or sublessee (notwithstanding Tenant remaining liable for Tenant’s performance), (b) any change in use that such transferee,
assignee or sublessee proposes to make in the use of the Premises and (c) Landlord’s desire to exercise its rights under Section 29.7 to recapture the Premises. In no event shall Landlord be deemed to be unreasonable for
declining to consent to a Transfer if the Transfer is to a transferee, assignee or sublessee of poor reputation, lacking financial qualifications or seeking a change in the Permitted Use, or jeopardizing directly or indirectly the status of Landlord
or any of Landlord’s affiliates as a Real Estate Investment Trust under the Internal Revenue Code of 1986 (as the same may be amended from time to time, the “Revenue Code”). Notwithstanding anything contained in this Lease to
the contrary, (w) no Transfer shall be consummated on any basis such that the rental or other amounts to be paid by the occupant, assignee, manager or other transferee thereunder would be based, in whole or in part, on the income or profits
derived by the business activities of such occupant, assignee, manager or other transferee; (x) Tenant shall not furnish or render any services to an occupant, assignee, manager or other transferee with respect to whom transfer consideration is
required to be paid, or manage or operate the Premises or any capital additions so transferred, with respect to which transfer consideration is being paid; (y) Tenant shall not consummate a Transfer with any person in which Landlord owns an
interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Revenue Code); and (z) Tenant shall not consummate a Transfer with any person or in any manner that could cause any portion of
the amounts received by Landlord pursuant to this Lease or any sublease, license or other arrangement for the right to use, occupy or possess any portion of the Premises to fail to qualify as “rents from real property” within the meaning
of Section 856(d) of the Revenue Code, or any similar or successor provision thereto or which could cause any other income of Landlord to fail to qualify as income described in Section 856(c)(2) of the Revenue Code. Notwithstanding
anything in this Lease to the contrary, if (a) Tenant or any proposed transferee, assignee or sublessee of Tenant has been required by any prior landlord, Lender or Governmental Authority to take material remedial action in connection with
Hazardous Materials contaminating a property if the contamination resulted from such party’s action or omission or use of the property in question or (b) Tenant or any proposed transferee, assignee or sublessee is subject to a material
enforcement order issued by any Governmental Authority in connection with the use, disposal or storage of Hazardous Materials, it shall not be unreasonable for Landlord to withhold its consent to any proposed transfer, assignment or subletting (with
respect to any such matter involving a proposed transferee, assignee or sublessee). 
 29.4 The following are conditions precedent to a
Transfer or to Landlord considering a request by Tenant to a Transfer: 

  
 48 













 (a) Tenant shall remain fully liable under this Lease. Tenant agrees that it shall not be
(and shall not be deemed to be) a guarantor or surety of this Lease, however, and waives its right to claim that is it is a guarantor or surety or to raise in any legal proceeding any guarantor or surety defenses permitted by this Lease or by
Applicable Laws; 
 (b) If Tenant or the proposed transferee, assignee or sublessee does not or cannot deliver the Required Financials, then
Landlord may elect to have either Tenant’s ultimate parent company or the proposed transferee’s, assignee’s or sublessee’s ultimate parent company provide a guaranty of the applicable entity’s obligations under this Lease,
in a form acceptable to Landlord, which guaranty shall be executed and delivered to Landlord by the applicable guarantor prior to the Transfer Date; 

(c) In the case of an Exempt Transfer, Tenant shall provide Landlord with evidence reasonably satisfactory to Landlord that the Transfer
qualifies as an Exempt Transfer; 
 (d) Tenant shall provide Landlord with evidence respecting the relevant business experience and financial
responsibility and status of the proposed transferee, assignee or sublessee; 
 (e) Tenant shall reimburse Landlord for Landlord’s
actual out of pocket costs and expenses, including reasonable attorneys’ fees, incurred in connection with the review, processing and documentation of such request; 

(f) If Tenant’s transfer of rights or sharing of the Premises provides for the receipt by, on behalf of or on account of Tenant of any
consideration of any kind whatsoever (including a premium rental for a sublease or lump sum payment for an assignment, but excluding Tenant’s reasonable costs in marketing and subleasing the Premises) in excess of the rental and other charges
due to Landlord under this Lease, Tenant shall (unless Landlord directs in writing otherwise) pay fifty percent (50%) of all of such excess to Landlord, after making deductions for any reasonable marketing expenses, tenant improvement funds
expended by Tenant, alterations, cash concessions, brokerage commissions, attorneys’ fees and free rent actually paid by Tenant. If such consideration consists of cash paid to Tenant, payment to Landlord shall be made upon receipt by Tenant of
such cash payment; 
 (g) The proposed transferee, assignee or sublessee shall agree that, in the event Landlord gives such proposed
transferee, assignee or sublessee notice that Tenant is in default under this Lease beyond applicable notice and cure periods, such proposed transferee, assignee or sublessee shall thereafter make all payments otherwise due Tenant directly to
Landlord, which payments shall be received by Landlord without any liability being incurred by Landlord, except to credit such payment against those due by Tenant under this Lease, and any such proposed transferee, assignee or sublessee shall agree
to attorn to Landlord or its successors and assigns should this Lease be terminated for any reason; provided, however, that in no event shall Landlord or its Lenders, successors or assigns be obligated to accept such attornment; 

(h) Landlord’s consent to any such Transfer shall be effected on Landlord’s forms; 

(i) Tenant shall not then be in default hereunder in any respect; 

  
 49 













 (j) Such proposed transferee, assignee or sublessee’s use of the Premises shall be the
same as the Permitted Use; 
 (k) Landlord shall not be bound by any provision of any agreement pertaining to the Transfer, except for
Landlord’s written consent to the same; 
 (l) Tenant shall pay all transfer and other taxes (including interest and penalties) assessed
or payable for any Transfer; 
 (m) Landlord’s consent (or waiver of its rights) for any Transfer shall not waive Landlord’s right
to consent or refuse consent to any later Transfer; 
 (n) Tenant shall deliver to Landlord one executed copy of any and all written
instruments evidencing or relating to the Transfer; and 
 (o) Tenant shall deliver to Landlord a list of Hazardous Materials (as defined
below), certified by the proposed transferee, assignee or sublessee to be true and correct, that the proposed transferee, assignee or sublessee intends to use or store in the Premises. Additionally, Tenant shall deliver to Landlord, on or before the
date any proposed transferee, assignee or sublessee takes occupancy of the Premises, all of the items relating to Hazardous Materials of such proposed transferee, assignee or sublessee as described in Section 21.2. 

29.5 Any Transfer that is not in compliance with the provisions of this Article or with respect to which Tenant does not fulfill its
obligations pursuant to this Article shall (a) constitute a Default, (b) be voidable by Landlord and (c), at Landlord’s option, terminate this Lease, except for those provisions that, by their express terms, survive the expiration or
earlier termination hereof. 
 29.6 Notwithstanding any Transfer, Tenant shall remain fully and primarily liable for the payment of all Rent
and other sums due or to become due hereunder, and for the full performance of all other terms, conditions and covenants to be kept and performed by Tenant. The acceptance of Rent or any other sum due hereunder, or the acceptance of performance of
any other term, covenant or condition thereof, from any person or entity other than Tenant shall not be deemed a waiver of any of the provisions of this Lease or a consent to any Transfer. 

29.7 If Tenant delivers to Landlord a Transfer Notice indicating a desire to transfer this Lease to a proposed transferee, assignee (excluding
any assignment constituting an Exempt Transfer), or sublessee, that would, in the aggregate with all other then-current subleases and licenses, cause more than fifty percent (50%) of the Rentable Area of the Premises to be assigned, licensed or
subleased (excluding any subleases and licenses that constitute Exempt Transfers) for substantially the remaining Term of this Lease, then Landlord shall have the option, exercisable by giving notice to Tenant at any time within thirty
(30) days after Landlord’s receipt of such Transfer Notice, to terminate this Lease as of the date specified in the Transfer Notice as the Transfer Date, except for those provisions that, by their express terms, survive the expiration or
earlier termination hereof. If Landlord exercises such option, then Tenant shall have the right to withdraw such Transfer Notice by delivering to Landlord written notice of such election within five (5) Business Days after Landlord’s
delivery of notice electing to exercise Landlord’s option to terminate this Lease. In the event Tenant withdraws the Transfer Notice as provided in this Section, this Lease shall continue in full force and effect. No failure of Landlord to
exercise its option to terminate this Lease shall be deemed to be Landlord’s consent to a proposed Transfer. 

  
 50 













 29.8 If Tenant sublets the Premises or any portion thereof, Tenant hereby immediately and
irrevocably assigns to Landlord, as security for Tenant’s obligations under this Lease, all rent from any such subletting, and appoints Landlord as assignee and attorney-in-fact for Tenant, and Landlord (or a receiver for Tenant appointed on
Landlord ‘s application) may collect such rent and apply it toward Tenant’s obligations under this Lease; provided that, until the occurrence of a Default (as defined below) by Tenant, Tenant shall have the right to collect such
rent. 
 29.9 In the event that Tenant enters into a sublease for the entire Premises in accordance with this Article that expires within two
(2) days of the Term Expiration Date, the term expiration date of such sublease shall, notwithstanding anything in this Lease, the sublease or any consent to the sublease to the contrary, be deemed to be the date that is two (2) days prior
to the Term Expiration Date. 
 30. Subordination and Attornment. 

30.1 This Lease shall be subject and subordinate to the lien of any mortgage, deed of trust, or lease in which Landlord is tenant now or
hereafter in force against the Building or the Project and to all advances made or hereafter to be made upon the security thereof without the necessity of the execution and delivery of any further instruments on the part of Tenant to effectuate such
subordination. 
 30.2 Notwithstanding the foregoing, Tenant shall execute and deliver upon demand such further instrument or instruments
evidencing such subordination of this Lease to the lien of any such mortgage or mortgages or deeds of trust or lease in which Landlord is tenant as may be required by Landlord. If any Lender so elects, however, Tenant’s leasehold shall be
deemed prior to any such lease, mortgage, or deed of trust upon or including the Premises regardless of date and Tenant shall execute a statement in writing to such effect at Landlord’s request. If Tenant fails to execute any document required
from Tenant under this Section within ten (10) days after written request therefor, then upon request of Landlord, Tenant shall pay a fee of $500.00 per day until Tenant has executed such document. Such power is coupled with an interest and is
irrevocable. Landlord shall request a SNDA from (a) its current Lender within thirty (30) days after the Term Commencement Date, and (b) any future Lender, each on Lenders’ standard form; provided, however, that Tenant
acknowledges and agrees that such Lenders have no contractual or other obligation to delivery such subordination and non- disturbance agreement. 

30.3 Upon written request of Landlord and opportunity for Tenant to review, Tenant agrees to execute any Lease amendments not materially
altering the terms of this Lease, if required by a Lender incident to the financing of the real property of which the Premises constitute a part. 

30.4 In the event any proceedings are brought for foreclosure, or in the event of the exercise of the power of sale under any mortgage or deed
of trust made by Landlord covering the Premises, Tenant shall at the election of the purchaser at such foreclosure or sale attorn to the purchaser upon any such foreclosure or sale and recognize such purchaser as Landlord under this Lease.

 31. Defaults and Remedies. 

31.1 Late payment by Tenant to Landlord of Rent and other sums due shall cause Landlord to incur costs not contemplated by this Lease, the
exact amount of which shall be extremely difficult and impracticable to ascertain. Such costs include processing and accounting charges and late charges that may be imposed on Landlord by the terms of any mortgage or trust deed covering the
Premises. Therefore, if any installment of Rent due from Tenant is not received by Landlord within three (3) days after the date such payment is due, Tenant shall pay to Landlord (a) an additional sum of five percent (5%) of the
overdue Rent as a late charge plus (b) interest at an annual rate (the “Default Rate”) equal to the lesser of (a) twelve percent (12%) and (b) the highest rate permitted by Applicable Laws. The parties agree that
this late charge represents a fair and reasonable estimate of the costs that Landlord shall incur by reason of late payment by Tenant and shall be payable as Additional Rent to Landlord due with the next installment of Rent or within five
(5) business days after Landlord’s demand, whichever is earlier. Landlord’s acceptance of any Additional Rent (including a late charge or any other amount hereunder) shall not be deemed an extension of the date that Rent is due or
prevent Landlord from pursuing any other rights or remedies under this Lease, at law or in equity. Notwithstanding the foregoing to the contrary, Landlord shall not charge Tenant such late charge the first time in any calendar year that Tenant fails
to make such payment within such three (3)- day period, provided such payment is made within ten (10) days after written notice from Landlord that such payment is due, and provided further that Tenant shall not be entitled to such extended
grace period more than twice during the Term of this Lease. 
 31.2 No payment by Tenant or receipt by Landlord of a lesser amount than the
Rent payment herein stipulated shall be deemed to be other than on account of the Rent, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction, and Landlord
may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other remedy provided in this Lease or in equity or at law. 

31.3 If Tenant fails to pay any sum of money required to be paid by it hereunder or perform any other act on its part to be performed
hereunder, in each case within the applicable cure period (if any) described in Section 31.4, then Landlord may (but shall not be obligated to), without waiving or releasing Tenant from any obligations of Tenant, make such payment or
perform such act; provided that such failure by Tenant unreasonably interfered with the use of the Building or the Project by any other tenant or with the efficient operation of the Building or the Project, or resulted or could have resulted in a
violation of Applicable Laws or the cancellation of an insurance policy maintained by Landlord. Notwithstanding the foregoing, in the event of an emergency, Landlord shall have the right to enter the Premises and act in accordance with its rights as
provided elsewhere in this Lease. In addition to the late charge described in Section 31.1, Tenant shall pay to Landlord as Additional Rent all sums so paid or incurred by Landlord, together with interest at the Default Rate, computed
from the date such sums were paid or incurred. 
 31.4 The occurrence of any one or more of the following events shall constitute a
“Default” hereunder by Tenant: 
 (a) Tenant abandons the Premises; 

  
 52 













 (b) Tenant fails to make any payment of Rent, as and when due, or to satisfy its obligations
under Article 19, where such failure shall continue for a period of three (3) Business Days after written notice thereof from Landlord to Tenant; 

(c) Tenant fails to observe or perform any obligation or covenant contained herein (other than described in Sections 31.4(a) and
31.4(b)) to be performed by Tenant, where such failure continues for a period of thirty (30) days after written notice thereof from Landlord to Tenant; provided that, if the nature of Tenant’s default is such that it
reasonably requires more than thirty (30) days to cure, Tenant shall not be deemed to be in Default if Tenant commences such cure within such thirty (30) day period and thereafter diligently prosecutes the same to completion; and
provided, further, that such cure is completed no later than sixty (60) days after Tenant’s receipt of written notice from Landlord; 

(d) Tenant makes an assignment for the benefit of creditors; 

(e) A receiver, trustee or custodian is appointed to or does take title, possession or control of all or substantially all of Tenant’s
assets; 
 (f) Tenant files a voluntary petition under the United States Bankruptcy Code or any successor statute (as the same may be amended
from time to time, the “Bankruptcy Code”) or an order for relief is entered against Tenant pursuant to a voluntary or involuntary proceeding commenced under any chapter of the Bankruptcy Code; 

(g) Any involuntary petition is filed against Tenant under any chapter of the Bankruptcy Code and is not dismissed within one hundred twenty
(120) days; 
 (h) Tenant fails to deliver an estoppel certificate in accordance with Article 20, and such failure continues for more
than five (5) days after notice from Landlord; or 
 (i) Tenant’s interest in this Lease is attached, executed upon or otherwise
judicially seized and such action is not released or vacated within one hundred twenty (120) days of the action. 
 Notices given under this Section
shall specify the alleged default and shall demand that Tenant perform the provisions of this Lease or pay the Rent that is in arrears, as the case may be, within the applicable period of time, or quit the Premises. No such notice shall be deemed a
forfeiture or a termination of this Lease unless Landlord elects otherwise in such notice. 
 31.5 In the event of a Chronic Delinquency (as
defined below), Landlord may, in addition to all other remedies under this Lease, at law or in equity, require that Tenant thereafter pay Rent quarterly in advance. This provision shall not limit in any way nor be construed as a waiver of
Landlord’s rights and remedies contained in this Lease, at law or in equity in the event of a default. “Chronic Delinquency” means that Tenant commits a Default pursuant to Section 31.4(b) three (3) times in any
twelve (12) month period. 
 31.6 In the event of a Default by Tenant, and at any time thereafter, with or without notice or demand and
without limiting Landlord in the exercise of any right or remedy that Landlord may have, Landlord has the right to do any or all of the following: 

  
 53 













 (a) Halt any Tenant Improvements and Alterations and order Tenant’s contractors,
subcontractors, consultants, designers and material suppliers to stop work; 
 (b) Terminate Tenant’s right to possession of the
Premises by written notice to Tenant or by any lawful means, in which case Tenant shall immediately surrender possession of the Premises to Landlord. In such event, Landlord shall have the immediate right to re-enter and remove all persons and
property, and such property may be removed and stored in a public warehouse or elsewhere at the cost and for the account of Tenant, all without service of notice or resort to legal process and without being deemed guilty of trespass or becoming
liable for any loss or damage that may be occasioned thereby; and 
 (c) Terminate this Lease, in which event Tenant shall immediately
surrender possession of the Premises to Landlord. In such event, Landlord shall have the immediate right to re-enter and remove all persons and property, and such property may be removed and stored in a public warehouse or elsewhere at the cost and
for the account of Tenant, all without service of notice or resort to legal process and without being deemed guilty of trespass or becoming liable for any loss or damage that may be occasioned thereby. In the event that Landlord shall elect to so
terminate this Lease, then Landlord shall be entitled to recover from Tenant all damages incurred by Landlord by reason of Tenant’s default, including, 

(i) The sum of: 

(A) The worth at the time of award of any unpaid Rent that had accrued at the time of such termination; plus 

(B) The costs of restoring the Premises to the condition required under the terms of this Lease; plus 

(C) An amount (the “Election Amount”) equal to either (A) the positive difference (if any, and measured
at the time of such termination) between (1) the then-present value of the total Rent and other benefits that would have accrued to Landlord under this Lease for the remainder of the Term if Tenant had fully complied with the Lease minus
(2) the then-present cash rental value of the Premises as determined by Landlord for what would be the then-unexpired Term if the Lease remained in effect, computed using the discount rate of the Federal Reserve Bank of San Francisco at the
time of the award plus one (1) percentage point (the “Discount Rate”) or (B) twelve (12) months (or such lesser number of months as may then be remaining in the Term) of Base Rent and Additional Rent at the rate last
payable by Tenant pursuant to this Lease, in either case as Landlord specifies in such election. Landlord and Tenant agree that the Election Amount represents a reasonable forecast of the minimum damages expected to occur in the event of a breach,
taking into account the uncertainty, time and cost of determining elements relevant to actual damages, such as fair market rent, time and costs that may be required to re-lease the Premises, and other factors; and that the Election Amount is not a
penalty. 
 As used in Section 31.6(c)(i), “worth at the time of award” shall be computed by allowing interest at the Default Rate.


  
 54 













 31.7 In addition to any other remedies available to Landlord at law or in equity and under
this Lease, Landlord may continue this Lease in effect after Tenant’s Default or abandonment and recover Rent as it becomes due. In addition, Landlord shall not be liable in any way whatsoever for its failure or refusal to relet the Premises.
For purposes of this Section, the following acts by Landlord will not constitute the termination of Tenant’s right to possession of the Premises: 

(a) Acts of maintenance or preservation or efforts to relet the Premises, including alterations, remodeling, redecorating, repairs,
replacements or painting as Landlord shall consider advisable for the purpose of reletting the Premises or any part thereof; or 
 (b) The
appointment of a receiver upon the initiative of Landlord to protect Landlord’s interest under this Lease or in the Premises. 
 Notwithstanding the
foregoing, in the event of a Default by Tenant, Landlord may elect at any time to terminate this Lease and to recover damages to which Landlord is entitled. 

31.8 If Landlord does not elect to terminate this Lease as provided in Section 31.6, then Landlord may, from time to time, recover
all Rent as it becomes due under this Lease. At any time thereafter, Landlord may elect to terminate this Lease and to recover damages to which Landlord is entitled. 

31.9 In the event Landlord elects to terminate this Lease and relet the Premises, Landlord may execute any new lease in its own name. Tenant
shall have no right or authority whatsoever to collect any Rent from such tenant. The proceeds of any such reletting shall be applied as follows: 

(a) First, to the payment of any indebtedness other than Rent due hereunder from Tenant to Landlord, including storage charges or brokerage
commissions owing from Tenant to Landlord as the result of such reletting; 
 (b) Second, to the payment of the costs and expenses of
reletting the Premises, including (i) alterations and repairs that Landlord deems reasonably necessary and advisable and (ii) reasonable attorneys’ fees, charges and disbursements incurred by Landlord in connection with the retaking
of the Premises and such reletting; 
 (c) Third, to the payment of Rent and other charges due and unpaid hereunder; and 

(d) Fourth, to the payment of future Rent and other damages payable by Tenant under this Lease. 

31.10 All of Landlord’s rights, options and remedies hereunder shall be construed and held to be nonexclusive and cumulative. Landlord
shall have the right to pursue any one or all of such remedies, or any other remedy or relief that may be provided by Applicable Laws, whether or not stated in this Lease. No waiver of any default of Tenant hereunder shall be implied from any
acceptance by Landlord of any Rent or other payments due hereunder or any omission by Landlord to take any action on account of such default if such default persists or is repeated, and no express waiver shall affect defaults other than as specified
in such waiver. Notwithstanding 

  
 55 













 
any provision of this Lease to the contrary, in no event shall Landlord be required to mitigate its damages with respect to any default by Tenant, except as required by Applicable Laws. Any such
obligation imposed by Applicable Laws upon Landlord to relet the Premises after any termination of this Lease shall be subject to the reasonable requirements of Landlord to (a) lease to high quality tenants on such terms as Landlord may from
time to time deem appropriate in its discretion and (b) develop the Project in a harmonious manner with a mix of uses, tenants, floor areas, terms of tenancies, etc., as determined by Landlord. Landlord shall not be obligated to relet the
Premises to (y) any Tenant’s Affiliate or (z) any party (i) unacceptable to a Lender, (ii) that requires Landlord to make improvements to or re-demise the Premises, (iii) that desires to change the Permitted Use,
(iv) that desires to lease the Premises for more or less than the remaining Term or (v) to whom Landlord or an affiliate of Landlord may desire to lease other available space in the Project or at another property owned by Landlord or an
affiliate of Landlord. 
 31.11 Landlord’s termination of (a) this Lease or (b) Tenant’s right to possession of the
Premises shall not relieve Tenant of any liability to Landlord that has previously accrued or that shall arise based upon events that occurred prior to the later to occur of (y) the date of Lease termination and (z) the date Tenant
surrenders possession of the Premises. 
 31.12 To the extent permitted by Applicable Laws, Tenant waives any and all rights of redemption
granted by or under any present or future Applicable Laws if Tenant is evicted or dispossessed for any cause, or if Landlord obtains possession of the Premises due to Tenant’s default hereunder or otherwise. 

31.13 Landlord shall not be in default or liable for damages under this Lease unless Landlord fails to perform obligations required of Landlord
within a reasonable time, but in no event shall such failure continue for more than thirty (30) days after written notice from Tenant specifying the nature of Landlord’s failure; provided, however, that if the nature of
Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently
prosecutes the same to completion. In no event shall Tenant have the right to terminate or cancel this Lease or to withhold or abate rent or to set off any Claims against Rent as a result of any default or breach by Landlord of any of its covenants,
obligations, representations, warranties or promises hereunder, except as may otherwise be expressly set forth in this Lease. 
 31.14 In the
event of any default by Landlord, Tenant shall give notice by registered or certified mail or overnight delivery with a reputable overnight delivery service to any (a) beneficiary of a deed of trust or (b) mortgagee under a mortgage
covering the Premises, the Building or the Project and to any landlord of any lease of land upon or within which the Premises, the Building or the Project is located, and shall offer such beneficiary, mortgagee or landlord a reasonable opportunity
to cure the default, including time to obtain possession of the Building or the Project by power of sale or a judicial action if such should prove necessary to effect a cure; provided that Landlord shall furnish to Tenant in writing, upon
written request by Tenant, the names and addresses of all such persons who are to receive such notices. 

  
 56 













 32. Bankruptcy. In the event a debtor, trustee or debtor in possession under the Bankruptcy Code, or
another person with similar rights, duties and powers under any other Applicable Laws, proposes to cure any default under this Lease or to assume or assign this Lease and is obliged to provide adequate assurance to Landlord that (a) a default
shall be cured, (b) Landlord shall be compensated for its damages arising from any breach of this Lease and (c) future performance of Tenant’s obligations under this Lease shall occur, then such adequate assurances shall include any
or all of the following, as designated by Landlord in its sole and absolute discretion: 
 32.1 Those acts specified in the Bankruptcy Code
or other Applicable Laws as included within the meaning of “adequate assurance,” even if this Lease does not concern a shopping center or other facility described in such Applicable Laws; 

32.2 A prompt cash payment to compensate Landlord for any monetary defaults or actual damages arising directly from a breach of this Lease;

 32.3 A cash deposit in an amount at least equal to the then-current amount of the Security Deposit; or 

32.4 The assumption or assignment of all of Tenant’s interest and obligations under this Lease. 

33. Brokers. 
 33.1 Tenant represents and
warrants that it has had no dealings with any real estate broker or agent in connection with the negotiation of this Lease other than CBRE, Inc. (“Broker”), and that it knows of no other real estate broker or agent that is or might
be entitled to a commission in connection with this Lease. Landlord shall compensate Broker in relation to this Lease pursuant to a separate agreement between Landlord and Broker. 

33.2 Tenant represents and warrants that no broker or agent has made any representation or warranty relied upon by Tenant in Tenant’s
decision to enter into this Lease, other than as contained in this Lease. 
 33.3 Tenant acknowledges and agrees that the employment of
brokers by Landlord is for the purpose of solicitation of offers of leases from prospective tenants and that no authority is granted to any broker to furnish any representation (written or oral) or warranty from Landlord unless expressly contained
within this Lease. Landlord is executing this Lease in reliance upon Tenant’s representations, warranties and agreements contained within Sections 33.1 and 33.2. 

33.4 Tenant agrees to Indemnify the Landlord Indemnitees from any and all cost or liability for compensation claimed by any broker or agent,
other than Broker, employed or engaged by Tenant or claiming to have been employed or engaged by Tenant. 
 34. Definition of Landlord. With regard
to obligations imposed upon Landlord pursuant to this Lease, the term “Landlord,” as used in this Lease, shall refer only to Landlord or Landlord’s then-current successor-in-interest. In the event of any transfer, assignment or
conveyance of Landlord’s interest in this Lease or in Landlord’s fee title to or leasehold interest in the Property, as applicable, Landlord herein named (and in case of any subsequent transfers or conveyances, the subsequent Landlord)
shall be automatically freed and relieved, from and after the date of such transfer, assignment or conveyance, from all liability for the performance of any covenants or obligations contained in this Lease thereafter to be performed by Landlord and,
without further 

  
 57 













 
agreement, the transferee, assignee or conveyee of Landlord ‘s in this Lease or in Landlord’s fee title to or leasehold interest in the Property, as applicable, shall be deemed to have
assumed and agreed to observe and perform any and all covenants and obligations of Landlord hereunder during the tenure of its interest in the Lease or the Property. Landlord or any subsequent Landlord may transfer its interest in the Premises or
this Lease without Tenant’s consent. 
 35. Limitation of Landlord’s Liability. 

35.1 If Landlord is in default under this Lease and, as a consequence, Tenant recovers a monetary judgment against Landlord, the judgment shall
be satisfied only out of (a) the proceeds of sale received on execution of the judgment and levy against the right, title and interest of Landlord in the Building and the Project, (b) rent or other income from such real property receivable
by Landlord or (c) the consideration received by Landlord from the sale, financing, refinancing or other disposition of all or any part of Landlord’s right, title or interest in the Building or the Project. 

35.2 Neither Landlord nor any of its affiliates, nor any of their respective partners, shareholders, directors, officers, employees, members or
agents shall be personally liable for Landlord’s obligations or any deficiency under this Lease, and service of process shall not be made against any shareholder, director, officer, employee or agent of Landlord or any of Landlord’s
affiliates. No partner, shareholder, director, officer, employee, member or agent of Landlord or any of its affiliates shall be sued or named as a party in any suit or action, and service of process shall not be made against any partner or member of
Landlord except as may be necessary to secure jurisdiction of the partnership, joint venture or limited liability company, as applicable. No partner, shareholder, director, officer, employee, member or agent of Landlord or any of its affiliates
shall be required to answer or otherwise plead to any service of process, and no judgment shall be taken or writ of execution levied against any partner, shareholder, director, officer, employee, member or agent of Landlord or any of its affiliates.

 35.3 Each of the covenants and agreements of this Article shall be applicable to any covenant or agreement either expressly contained in
this Lease or imposed by Applicable Laws and shall survive the expiration or earlier termination of this Lease. 
 36. Joint and Several Obligations.
If more than one person or entity executes this Lease as Tenant, then: 
 36.1 Each of them is jointly and severally liable for the keeping,
observing and performing of all of the terms, covenants, conditions, provisions and agreements of this Lease to be kept, observed or performed by Tenant, and such terms, covenants, conditions, provisions and agreements shall be binding with the same
force and effect upon each and all of the persons executing this Agreement as Tenant; and 
 36.2 The term “Tenant,” as used
in this Lease, means and includes each of them, jointly and severally. The act of, notice from, notice to, refund to, or signature of any one or more of them with respect to the tenancy under this Lease, including any renewal, extension, expiration,
termination or modification of this Lease, shall be binding upon each and all of the persons executing this Lease as Tenant with the same force and effect as if each and all of them had so acted, so given or received such notice or refund, or so
signed. 

  
 58 













 37. Representations. Tenant guarantees, warrants and represents that (a) Tenant is duly
incorporated or otherwise established or formed and validly existing under the laws of its state of incorporation, establishment or formation, (b) Tenant has and is duly qualified to do business in the state in which the Property is located,
(c) Tenant has full corporate, partnership, trust, association or other appropriate power and authority to enter into this Lease and to perform all Tenant’s obligations hereunder, (d) each person (and all of the persons if more than
one signs) signing this Lease on behalf of Tenant is duly and validly authorized to do so and (e) neither (i) the execution, delivery or performance of this Lease nor (ii) the consummation of the transactions contemplated hereby will
violate or conflict with any provision of documents or instruments under which Tenant is constituted or to which Tenant is a party. In addition, Tenant guarantees, warrants and represents that none of (x) it, (y) its affiliates or partners
nor (z) to the best of its knowledge, its members, shareholders or other equity owners or any of their respective employees, officers, directors, representatives or agents is a person or entity with whom U.S. persons or entities are restricted
from doing business under regulations of the Office of Foreign Asset Control (“OFAC”) of the Department of the Treasury (including those named on OFAC’s Specially Designated and Blocked Persons List) or under any statute,
executive order (including the September 24, 2001, Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism) or other similar governmental action. 

38. Confidentiality. Tenant shall keep the terms and conditions of this Lease and any information provided to Tenant or its employees, agents or
contractors pursuant to Article 9 confidential and shall not (a) disclose to any third party any terms or conditions of this Lease or any other Lease-related document (including subleases, assignments, work letters, construction
contracts, letters of credit, subordination agreements, non-disturbance agreements, brokerage agreements or estoppels) or the contents of any documents, reports, surveys or evaluations related to the Project or any portion thereof or
(b) provide to any third party an original or copy of this Lease (or any Lease-related document or other document referenced in Subsection 38(a)). Landlord shall not release to any third party any non-public financial information or
non-public information about Tenant’s ownership structure that Tenant gives Landlord. Notwithstanding the foregoing, confidential information under this Section may be released by Landlord or Tenant under the following circumstances:
(w) if required by Applicable Laws or in any judicial proceeding; provided that the releasing party has given the other party reasonable notice of such requirement, if feasible, (x) to a party’s attorneys, accountants, brokers,
lenders, potential lenders, investors, potential investors and other bona fide consultants or advisers (with respect to this Lease only); provided such third parties agree to be bound by this Section, (y) to a party’s lenders for
purposes of financial reporting or (z) to bona fide prospective assignees or subtenants of this Lease; provided they agree in writing to be bound by this Section. 

39. Notices. Except as otherwise stated in this Lease, any notice, consent, demand, invoice, statement or other communication required or permitted to
be given hereunder shall be in writing and shall be given by (a) personal delivery, (b) overnight delivery with a reputable international overnight delivery service, such as FedEx, or (c) email transmission, so long as such
transmission is followed within one (1) business day by delivery utilizing one of the methods described in Subsection 39(a) or (b), provided that, for purposes of this Subsection 39(c), if delivery utilizing 

  
 59 













 
one of the other methods described in Subsection 39(a) or (b) is not reasonably practicable due to an event of Force Majeure (as defined below), then such requirement shall be
waived for deliveries by email transmission so long as either the receiving party responds to the sending party confirming receipt of the applicable email transmission, or the sending party receives other electronic confirmation that the email
transmission was received and read by the receiving party, such as a “read receipt” notice. Any such notice, consent, demand, invoice, statement or other communication shall be deemed delivered (x) upon receipt, if given in accordance
with Subsection 39(a); (y) one (1) business day after deposit with a reputable international overnight delivery service, if given in accordance with Subsection 39(b); or (z) upon transmission, if given in accordance

to Landlord or Tenant at the addresses shown in Sections 2.9 and 2.10 or 2.11, respectively. Either party may, by notice to the other given pursuant to this Section, specify additional or different addresses for notice purposes.

 40. Miscellaneous. 
 40.1 Landlord
reserves the right to change the name of the Building or the Project in its sole discretion. 
 40.2 To induce Landlord to enter into this
Lease, Tenant agrees that it shall furnish to Landlord, from time to time, within ten (10) business days after receipt of Landlord’s written request, given not more than once in any twelve-month period, the most recent year-end
unconsolidated financial statements reflecting Tenant’s current financial condition audited by a nationally recognized accounting firm. Tenant shall, within ninety (90) days after the end of Tenant’s financial year, furnish Landlord
with a certified copy of Tenant’s year-end unconsolidated financial statements for the previous year audited by a nationally recognized accounting firm. Tenant represents and warrants that all financial statements, records and information
furnished by Tenant to Landlord in connection with this Lease are true, correct and complete in all respects. If audited financials are not otherwise prepared, unaudited financials complying with generally accepted accounting principles and
certified by the chief financial officer of Tenant as true, correct and complete in all respects shall suffice for purposes of this Section. If Tenant fails to deliver to Landlord any financial statement within the time period required under this
Section, then Tenant shall be required to pay to Landlord an administrative fee equal to Five Hundred Dollars ($500) within five (5) business days after receiving written notice from Landlord advising Tenant of such failure (provided,
however, that Landlord’s acceptance of such fee shall not prevent Landlord from pursuing any other rights or remedies under this Lease, at law or in equity). The provisions of this Section shall not apply at any time while Tenant is a
corporation whose shares are traded on any nationally recognized stock exchange. 
 40.3 Submission of this instrument for examination or
signature by Tenant does not constitute a reservation of or option for a lease, and shall not be effective as a lease or otherwise until execution by and delivery to both Landlord and Tenant. 

40.4 The terms of this Lease are intended by the parties as a final, complete and exclusive expression of their agreement with respect to the
terms that are included herein, and may not be contradicted or supplemented by evidence of any other prior or contemporaneous agreement. 

  
 60 













 40.5 Upon the request of either Landlord or Tenant, the parties shall execute a document in
recordable form containing only such information as is necessary to constitute a Notice of Lease under Massachusetts law. All costs of preparing and recording such notice shall be borne by the requesting party. Within ten (10) days after
receipt of written request from Landlord after the expiration or earlier termination of this Lease, Tenant shall execute a termination of any Notice of Lease recorded with respect hereto. Neither party shall record this Lease. 

40.6 Where applicable in this Lease, the singular includes the plural and the masculine or neuter includes the masculine, feminine and neuter.
The words “include,” “includes,” “included” and “including” mean “‘include,’ etc., without limitation.” The word “shall” is mandatory and the word “may” is permissive.
The word “business day” means a calendar day other than any national or local holiday on which federal government agencies in the County of Suffolk are closed for business, or any weekend. The section headings of this Lease are not a part
of this Lease and shall have no effect upon the construction or interpretation of any part of this Lease. Landlord and Tenant have each participated in the drafting and negotiation of this Lease, and the language in all parts of this Lease shall be
in all cases construed as a whole according to its fair meaning and not strictly for or against either Landlord or Tenant. 
 40.7 Except as
otherwise expressly set forth in this Lease, each party shall pay its own costs and expenses incurred in connection with this Lease and such party’s performance under this Lease; provided that, if either party commences an action,
proceeding, demand, claim, action, cause of action or suit against the other party arising from or in connection with this Lease, then the substantially prevailing party shall be reimbursed by the other party for all reasonable costs and expenses,
including reasonable attorneys’ fees and expenses, incurred by the substantially prevailing party in such action, proceeding, demand, claim, action, cause of action or suit, and in any appeal in connection therewith (regardless of whether the
applicable action, proceeding, demand, claim, action, cause of action, suit or appeal is voluntarily withdrawn or dismissed). In addition, Landlord shall, upon demand, be entitled to all reasonable attorneys’ fees and all other reasonable costs
incurred in the preparation and service of any notice or demand hereunder, regardless of whether a legal action is subsequently commenced, or incurred in connection with any proceeding in bankruptcy court concerning this Lease. 

40.8 Time is of the essence with respect to the performance of every provision of this Lease. 

40.9 Each provision of this Lease performable by Tenant shall be deemed both a covenant and a condition. 

40.10 Notwithstanding anything to the contrary contained in this Lease, Tenant’s obligations under this Lease are independent and shall
not be conditioned upon performance by Landlord. 
 40.11 Any provision of this Lease that shall prove to be invalid, void or illegal shall
in no way affect, impair or invalidate any other provision hereof, and all other provisions of this Lease shall remain in full force and effect and shall be interpreted as if the invalid, void or illegal provision did not exist. 

  
 61 













 40.12 Each of the covenants, conditions and agreements herein contained shall inure to the
benefit of and shall apply to and be binding upon the parties hereto and their respective heirs; legatees; devisees; executors; administrators; and permitted successors and assigns. This Lease is for the sole benefit of the parties and their
respective heirs, legatees, devisees, executors, administrators and permitted successors and assigns, and nothing in this Lease shall give or be construed to give any other person or entity any legal or equitable rights. Nothing in this Section
shall in any way alter the provisions of this Lease restricting assignment or subletting. 
 40.13 This Lease shall be governed by, construed
and enforced in accordance with the laws of the state in which the Premises are located, without regard to such state’s conflict of law principles. 

40.14 Tenant guarantees, warrants and represents that the individual or individuals signing this Lease have the power, authority and legal
capacity to sign this Lease on behalf of and to bind all entities, corporations, partnerships, limited liability companies, joint venturers or other organizations and entities on whose behalf such individual or individuals have signed. 

40.15 This Lease may be executed in one or more counterparts, each of which, when taken together, shall constitute one and the same document.

 40.16 No provision of this Lease may be modified, amended or supplemented except by an agreement in writing signed by Landlord and Tenant.

 40.17 No waiver of any term, covenant or condition of this Lease shall be binding upon Landlord unless executed in writing by Landlord.
The waiver by Landlord of any breach or default of any term, covenant or condition contained in this Lease shall not be deemed to be a waiver of any preceding or subsequent breach or default of such term, covenant or condition or any other term,
covenant or condition of this Lease. 
 40.18 To the extent permitted by Applicable Laws, the parties waive trial by jury in any action,
proceeding or counterclaim brought by the other party hereto related to matters arising from or in any way connected with this Lease; the relationship between Landlord and Tenant; Tenant’s use or occupancy of the Premises; or any claim of
injury or damage related to this Lease or the Premises. 
 40.19 A facsimile, electronic or portable document format (PDF) signature on this
Lease or any other document required or permitted by this Lease to be delivered by Landlord or Tenant shall be equivalent to, and have the same force and effect as, an original signature. 

40.20 For purposes of this Lease, “Force Majeure” means accidents; breakage; casualties (to the extent not caused by the party
claiming Force Majeure); Severe Weather Conditions (as defined below); physical natural disasters (but excluding weather conditions that are not Severe Weather Conditions); strikes, lockouts or other labor disturbances or labor disputes (other than
labor disturbances and labor disputes resulting solely from the acts or omissions of the party claiming Force Majeure); acts of terrorism; riots or civil disturbances; wars or insurrections; plagues, epidemics, pandemics, or public health crises
(including regulations, actions or delays by Governmental Authorities resulting from any such plague, epidemic, pandemic or public health crisis); shortages of materials and supply chain disruptions (which shortages and disruptions are


  
 62 













 
not unique to the party claiming Force Majeure); regulations, moratoria or other actions, inactions or delays by Governmental Authorities, provided that any delay by a Governmental
Authority in issuing any required permit or approval is not caused by the failure of the party claiming Force Majeure to timely submit a complete application for such permit or approval in compliance with Applicable Laws; failures by third parties
to deliver gas, oil or another suitable fuel supply, or inability of the party claiming Force Majeure, by exercise of reasonable diligence, to obtain gas, oil or another suitable fuel; or other causes beyond the reasonable control of the party
claiming that Force Majeure has occurred. “Severe Weather Conditions” means weather conditions that are materially worse than those that would be reasonably anticipated for the Property at the applicable time based on historic
meteorological records. Notwithstanding anything in this Lease to the contrary, events of Force Majeure shall excuse timely performance of a party hereunder (other than either party’s obligation to pay any amounts hereunder, which shall
not be excused by Force Majeure) for a period equal to the delay caused thereby and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in
such party’s performance caused by an event of Force Majeure. Each party claiming any delay as a result of Force Majeure shall notify the other party in writing within ten (10) business days after it acquires actual knowledge of the event
constituting an event of Force Majeure, which written notice shall state in reasonable detail the nature of such event, the reason(s) that such event constitutes an event of Force Majeure, and the manner in which such event has or will delay
performance of the claiming party’s obligations hereunder. 
 41. Rooftop Installation Area. 

41.1 Tenant shall not have the right to install any equipment on the roof of the Building without Landlord’s consent in its sole
discretion. In the event that Landlord identifies portions of the Building (the “Rooftop Installation Area”) to be used to operate, maintain, repair and replace rooftop antennae, mechanical equipment, communications antennas and
other equipment installed by Tenant in the Rooftop Installation Area (“Tenant’s Rooftop Equipment”), the provisions of this Article shall apply. Tenant’s Rooftop Equipment shall be only for Tenant’s use of the
Premises for the Permitted Use. 
 41.2 Tenant shall install Tenant’s Rooftop Equipment at its sole cost and expense, at such times and
in such manner as Landlord may reasonably designate, and in accordance with this Article and the applicable provisions of this Lease regarding Alterations. Tenant’s Rooftop Equipment and the installation thereof shall be subject to
Landlord’s prior written approval, which approval shall not be unreasonably withheld. Among other reasons, Landlord may withhold approval if the installation or operation of Tenant’s Rooftop Equipment could reasonably be expected to damage
the structural integrity of the Building or to transmit vibrations or noise or cause other adverse effects beyond the Premises to an extent not customary in first class laboratory buildings, unless Tenant implements measures that are acceptable to
Landlord in its reasonable discretion to avoid any such damage or transmission. 
 41.3 Tenant shall comply with any roof or roof-related
warranties. Tenant shall obtain a letter from Landlord’s roofing contractor within thirty (30) days after completion of any Tenant work on the rooftop stating that such work did not affect any such warranties. Tenant, at its sole cost and
expense, shall inspect the Rooftop Installation Area at least annually, and correct any loose bolts, fittings or other appurtenances and repair any damage to the roof arising from the 

  
 63 













 
installation or operation of Tenant’s Rooftop Equipment. Tenant shall not permit the installation, maintenance or operation of Tenant’s Rooftop Equipment to violate any Applicable Laws
or constitute a nuisance. Tenant shall pay Landlord within thirty (30) days after demand (a) all applicable taxes, charges, fees or impositions imposed on Landlord by Governmental Authorities as the result of Tenant’s use of the
Rooftop Installation Areas in excess of those for which Landlord would otherwise be responsible for the use or installation of Tenant’s Rooftop Equipment and (b) the amount of any increase in Landlord’s insurance premiums as a result
of the installation of Tenant’s Rooftop Equipment. Upon Tenant’s written request to Landlord, Landlord shall use commercially reasonable efforts to cause other tenants to remedy any interference in the operation of Tenant’s Rooftop
Equipment arising from any such tenants’ equipment installed after the applicable piece of Tenant’s Rooftop Equipment; provided, however, that Landlord shall not be required to request that such tenants waive their rights
under their respective leases. 
 41.4 If Tenant’s Equipment (a) causes physical damage to the structural integrity of the
Building, (b) interferes with any telecommunications, mechanical or other systems located at or near or servicing the Building or the Project that were installed prior to the installation of Tenant’s Rooftop Equipment, (c) interferes
with any other service provided to other tenants in the Building or the Project by rooftop or penthouse installations that were installed prior to the installation of Tenant’s Rooftop Equipment or (d) interferes with any other
tenants’ business, in each case in excess of that permissible under Federal Communications Commission regulations, then Tenant shall cooperate with Landlord to determine the source of the damage or interference and promptly repair such damage
and eliminate such interference, in each case at Tenant’s sole cost and expense, within ten (10) days after receipt of notice of such damage or interference (which notice may be oral; provided that Landlord also delivers to Tenant
written notice of such damage or interference within twenty-four (24) hours after providing oral notice). 
 41.5 Landlord reserves the
right to cause Tenant to relocate Tenant’s Rooftop Equipment to comparably functional space on the roof or in the penthouse of the Building by giving Tenant prior written notice thereof. Landlord agrees to pay the reasonable costs thereof.
Tenant shall arrange for the relocation of Tenant’s Rooftop Equipment within sixty (60) days after receipt of Landlord’s notification of such relocation. In the event Tenant fails to arrange for relocation within such sixty (60)-day
period, Landlord shall have the right to arrange for the relocation of Tenant’s Rooftop Equipment in a manner that does not unnecessarily interrupt or interfere with Tenant’s use of the Premises for the Permitted Use. 

42. Option to Extend Term. Tenant shall have one (1) option (“Option”) to extend the Term by five (5) years as to the entire
Premises (and no less than the entire Premises) upon the following terms and conditions, provided that Tenant is personally occupying seventy-five percent (75%) or more of the Premises on the date the Option is exercised and on the commencement
of the Option term. Any extension of the Term pursuant to the Option shall be on all the same terms and conditions as this Lease, except as follows: 

42.1 Base Rent at the commencement of the Option term shall equal the greater of (a) the then-current Base Rent and (b) the
then-current fair market value for comparable office and laboratory space in the Boston market of comparable age, quality, level of finish and proximity to amenities and public transit, and containing the systems and improvements present in the
Premises as of the date that Tenant gives Landlord written notice of Tenant’s election to exercise the Option 

  
 64 













 
(“FMV”), and shall be further increased on each annual anniversary of the Option term commencement date by FMV market escalations. Tenant may, no more than fourteen
(14) months prior to the date the Term is then scheduled to expire, request Landlord’s estimate of the FMV for the Option term. Landlord shall, within fifteen (15) days after receipt of such request, give Tenant a written proposal of
such FMV. If Tenant gives written notice to exercise the Option, such notice shall specify whether Tenant accepts Landlord’s proposed estimate of FMV. If Tenant does not accept the FMV, then the parties shall endeavor to agree upon the FMV,
taking into account all relevant factors, including (v) the size of the Premises, (w) the length of the Option term, (x) rent in comparable buildings in the relevant market, including concessions offered to new tenants, such as free
rent, tenant improvement allowances and moving allowances, (y) Tenant’s creditworthiness and (z) the quality and location of the Building and the Project. In the event that the parties are unable to agree upon the FMV within thirty
(30) days after Tenant notifies Landlord that Tenant is exercising the Option, then either party may request that the same be determined as follows: a senior officer of a nationally recognized leasing brokerage firm with local knowledge of the
Boston laboratory/research and development leasing market (the “Baseball Arbitrator”) shall be selected and paid for jointly by Landlord and Tenant. If Landlord and Tenant are unable to agree upon the Baseball Arbitrator, then the
same shall be designated by the local chapter of the Judicial Arbitration and Mediation Services or any successor organization thereto (the “JAMS”). The Baseball Arbitrator selected by the parties or designated by JAMS shall
(y) have at least ten (10) years’ experience in the leasing of laboratory/research and development space in the Boston market and (z) not have been employed or retained by either Landlord or Tenant or any affiliate of either for
a period of at least ten (10) years prior to appointment pursuant hereto. Each of Landlord and Tenant shall submit to the Baseball Arbitrator and to the other party its determination of the FMV. The Baseball Arbitrator shall grant to Landlord
and Tenant a hearing and the right to submit evidence. The Baseball Arbitrator shall determine which of the two (2) FMV determinations more closely represents the actual FMV. The arbitrator may not select any other FMV for the Premises other
than one submitted by Landlord or Tenant. The FMV selected by the Baseball Arbitrator shall be binding upon Landlord and Tenant and shall serve as the basis for determination of Base Rent payable for the Option term. If, as of the commencement date
of the Option term, the amount of Base Rent payable during the Option term shall not have been determined, then, pending such determination, Tenant shall pay Base Rent equal to the Base Rent payable with respect to the last year of the then-current
Term. After the final determination of Base Rent payable for the Option term, the parties shall promptly execute a written amendment to this Lease specifying the amount of Base Rent to be paid during the Option term. Any failure of the parties to
execute such amendment shall not affect the validity of the FMV determined pursuant to this Section. 
 42.2 The Option is not assignable
separate and apart from this Lease. 
 42.3 The Option is conditional upon Tenant giving Landlord written notice of its election to exercise
the Option at least twelve (12) months prior to the end of the expiration of the then-current Term. Time shall be of the essence as to Tenant’s exercise of the Option. Tenant assumes full responsibility for maintaining a record of the
deadlines to exercise the Option. Tenant acknowledges that it would be inequitable to require Landlord to accept any exercise of the Option after the date provided for in this Section. 

  
 65 













 42.4 Notwithstanding anything contained in this Article to the contrary, Tenant shall not
have the right to exercise the Option: 
 (a) During the time commencing from the date Landlord delivers to Tenant a written notice that
Tenant is in default under any provisions of this Lease and continuing until Tenant has cured the specified default to Landlord’s reasonable satisfaction; or 

(b) At any time after any Default as described in Article 31 of the Lease (provided, however, that, for purposes of this
Section 42.4(b), Landlord shall not be required to provide Tenant with notice of such Default) and continuing until Tenant cures any such Default, if such Default is susceptible to being cured; or 

(c) In the event that Tenant has defaulted in the performance of its obligations under this Lease with respect to monetary or material
non-monetary obligations two (2) or more times during the twelve (12)-month period immediately prior to the date that Tenant intends to exercise the Option, whether or not Tenant has cured such defaults. 

42.5 The period of time within which Tenant may exercise the Option shall not be extended or enlarged by reason of Tenant’s inability to
exercise such Option because of the provisions of Section 42.4. 
 42.6 All of Tenant’s rights under the provisions of the
Option shall terminate and be of no further force or effect even after Tenant’s due and timely exercise of the Option if, after such exercise, but prior to the commencement date of the new term, (a) Tenant fails to pay to Landlord a
monetary obligation of Tenant for a period of twenty (20) days after written notice from Landlord to Tenant, or (b) Tenant fails to commence to cure a default (other than a monetary default) within thirty (30) days after the date
Landlord gives notice to Tenant of such default or (c) Tenant has defaulted under this Lease with respect to monetary or material non-monetary obligations two (2) or more times and a service or late charge under Section 31.1
has become payable for any such default, whether or not Tenant has cured such defaults.

the Lease. Tenant shall not be obligated to respond to or act upon any such item until such item has been initialed or signed (as applicable) by the appropriate Landlord’s Authorized Representative. Landlord may change either Landlord’s

completing the Tenant Improvements) and in substantial accordance with the Approved Plans (as defined below), the Lease and this Work Letter. To the extent that the total projected cost of the Tenant Improvements (as projected by Landlord) exceeds
the TI Allowance (such excess, the “Excess TI Costs”), Tenant shall pay the costs of the Tenant Improvements on a pari passu basis with Landlord as such costs become due, in the proportion of Excess TI Costs payable by Tenant to the
Base TI Allowance (and, if properly requested by Tenant pursuant to the Lease, the Additional TI Allowance) payable by Landlord. If the cost of the Tenant Improvements (as projected by Landlord) increases over Landlord’s initial projection,
then Landlord may notify Tenant and Tenant shall pay any additional Excess TI Costs with Landlord in the same way that Tenant deposited the initial Excess TI Costs. If Tenant fails to pay, or is late in paying, any sum due to Landlord under this
Work Letter, then Landlord shall have all of the rights and remedies set forth in the Lease for nonpayment of Rent (including the right to interest and the right to assess a late charge), and for purposes of any litigation instituted with regard to
such amounts the same shall be considered Rent. All material and equipment furnished by Landlord or its contractors as the Tenant Improvements shall be new or “like new” (provided all equipment shall be unused) and the Tenant Improvements
shall be performed in a first-class, workmanlike manner and in accordance with Applicable Laws.

Draft Schematic Plans and of the manner, if any, in which the Draft Schematic Plans are unacceptable. Tenant’s failure to respond within such ten (10) Business Day period shall be deemed a Tenant Delay equal to one day for each day beyond
such period that Tenant fails to respond. If Tenant reasonably objects to the Draft Schematic Plans, then Landlord shall revise the Draft Schematic Plans and cause Tenant’s objections to be remedied in the revised Draft Schematic Plans.
Landlord shall then resubmit the revised Draft Schematic Plans to Tenant for approval, such approval not to be unreasonably withheld, conditioned or delayed. Tenant’s approval of or objection to revised Draft Schematic Plans and Landlord’s
correction of the same shall be in accordance with this Section until Tenant has approved the Draft Schematic Plans in writing. The iteration of the Draft Schematic Plans that is approved by Tenant without objection shall be referred to herein as

the Tenant Improvements that (a) are consistent with and are logical evolutions of the Approved Schematic Plans and (b) incorporate any other Tenant-requested (and Landlord-approved) Changes (as defined below). As soon as such final plans
and specifications (“Construction Plans”) are completed, Landlord shall deliver the same to Tenant for Tenant’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Such Construction Plans shall
be approved or disapproved by Tenant within five (5) Business Days after delivery to Tenant. Tenant’s failure to respond within such five (5) Business Day period shall be shall be deemed a Tenant Delay equal to one day for each day

in good faith to reach agreement on the Construction Plans. Promptly after the Construction Plans are approved by Landlord and Tenant, two (2) copies of such Construction Plans shall be initialed and dated by Landlord and Tenant, and Landlord
shall promptly submit such Construction Plans to all appropriate Governmental Authorities for approval. The Construction Plans so approved, and all change orders specifically permitted by this Work Letter, are referred to herein as the
“Approved Plans.” 
 2.3. Changes to the Tenant Improvements. Any changes to the Approved Plans (each, a
“Change”) shall be requested and instituted in accordance with the provisions of this Article 2 and shall be subject to the written approval of the non-requesting party in accordance with this Work Letter. 

(a) Change Request. Either Landlord or Tenant may request Changes after Tenant approves the Approved Plans by notifying the other party
thereof in writing in substantially the same form as the AIA standard change order form (a “Change Request”), which Change Request shall detail the nature and extent of any requested Changes, including (a) the Change,
(b) the party required to perform the Change and (c) any modification of the Approved Plans and the Schedule, as applicable, necessitated by the Change. If the nature of a Change requires revisions to the Approved Plans, then the
requesting party shall be solely responsible for the cost and expense of such revisions and any increases in the cost of the Tenant Improvements as a result of such Change. Change Requests shall be signed by the requesting party’s Authorized
Representative. 
 (b) Approval of Changes. All Change Requests shall be subject to the other party’s prior written approval,
which approval shall not be unreasonably withheld, conditioned or delayed. The non-requesting party shall have five (5) Business days after receipt of a Change Request to notify the requesting party in writing of the non-requesting party’s

Allowance. Tenant may apply the Base TI Allowance and, if properly requested by Tenant pursuant to the terms of the Lease, the Additional TI Allowance for the payment of construction and other costs in accordance with the terms and provisions of the
Lease. 

  
 B-3

Ladies and Gentlemen: 
 We establish in favor of
Beneficiary our irrevocable and unconditional Letter of Credit numbered as identified above (the “L/C”) for an aggregate amount of $            , expiring at __:00

“Banking Day” means a weekday except a weekday when commercial banks in              are authorized or required to close. 

We authorize Beneficiary to draw on us (the “Issuer”) for the account of
             (the “Account Party”), under the terms and conditions of this L/C.

other means. Issuer will on request issue a receipt for Drawing Documentation. 
 We agree, irrevocably, and irrespective of any claim by
any other person, to honor drafts drawn under and in conformity with this L/C, within the maximum amount of this L/C, presented to us on or before the Expiry Date, provided we also receive (on or before the Expiry Date) any other Drawing

 Partial drawings are permitted. This L/C shall, except to the extent reduced thereby, survive
any partial drawings. 
 We shall have no duty or right to inquire into the validity of or basis for any draw under this L/C or any Drawing
Documentation. We waive any defense based on fraud or any claim of fraud.

for the extension to be effective. We need not give any notice of the Outside Date. 
 Beneficiary may from time to time without charge
transfer this L/C, in whole but not in part, to any transferee (the “Transferee”). Issuer shall look solely to Account Party for payment of any fee for any transfer of this L/C. Such payment is not a condition to any such transfer.

shall promptly reissue or amend this L/C in favor of Transferee as Beneficiary. Upon any transfer, all references to Beneficiary shall automatically refer to Transferee, who may then exercise all rights of Beneficiary. Issuer expressly consents to
any transfers made from time to time in compliance with this paragraph.

No amendment that adversely affects Beneficiary shall be effective without Beneficiary’s written consent. 

This L/C is subject to and incorporates by reference: (a) the International Standby Practices 98 (“ISP 98”); and
(b) to the extent not inconsistent with ISP 98, Article 5 of the Uniform Commercial Code of the State of New York.

 PART A: INTRODUCTION 

The Tenant Sustainable Design Guidelines describe the minimum sustainable design requirements to be provided under the tenant space design and construction.
The tenant plays an important role in reinforcing the building’s LEED-CS (Core & Shell) v3 2009 Silver certification features within their own workplaces. The tenant sustainable design guidelines are intended to support the 321
Harrison Avenue tenants in taking full advantage of the high-performance features of the building. 
 These guidelines will enable tenants to design and
implement sustainable, green building interiors that will benefit the overall health and quality of life for building occupants. 
 Please refer to the
Appendix A for the Owner’s LEED-CS Silver Scorecard. 
 While not required, the tenant may opt to pursue a LEED for Commercial Interiors (LEED ID+C) v4
certification or use the LEED ID+C criteria as a guideline. LEED ID+C supports high-performance, healthy, durable, affordable, and environmentally sound commercial interiors. A sample LEED ID+C v4 Scorecard is included as Appendix B for reference.

 PART B: TENANT MINIMUM SUSTAINABLE DESIGN REQUIREMENTS 

The Minimum Tenant Sustainable Design Requirements are to be included as part of the Tenant space fit out construction. The required sustainable design
measures may contribute in achieving LEED-CI v4 credits, in the case the tenant opts to pursue LEED ID+C certification. 
 Minimum Sustainable Design
Requirements 
  

	1.	 SUSTAINABLE SITES 



No tenant requirements. 
 Tenants will have access to the bike
racks and shower facilities provided by the facility owner. 
  

	2.	 WATER EFFICIENCY 



Indoor Potable Water Use—30% reduction 
 The base
building includes water efficient toilets, urinals, lavatory faucets, pre-rinse spray valves and showerheads. 
 If tenants install fixtures, they are
required to provide water efficient fixtures and appliances attaining a minimum of a 30% indoor water use reduction over the LEED V4 ID+C baseline. 

Maximum flow rates for Tenant Water Fixtures, Appliances, and Processes: 

Low Flow Water Closets (1.3 gpf) or Dual Flush Water Closets (1.6 gpf / 0.8 gpf) 

Waterless Urinals or Pint Flush Urinals (0.125 gpf) 

Ultra Low Flow Lavatories (0.5 gpm, limited to 12 second cycle time) 

Ultra Low Flow Kitchen Sinks (1.0 gpm) 

Ultra Low Flow Shower Fixtures (1.5 gpm) 

Residential Dishwashers (Energy Star) 

Commercial Dishwashers (CEE Tier 3A) 

Residential Clothes Washers (Energy Star or 4.5 WF (gallons/ft3/cycle)) 

Commercial Clothes Washer (CEE Tier 3A) 

Pre-rinse Spray Valve (1.3 gpm) 

Ice Machine (Energy Star or performance equivalent and use either air-cooled or closed-loop cooling) 

Heat Rejection and Cooling (No once-through cooling with potable water) 

Cooling Towers and Evaporative Condensers (equip with water meters, conductivity controllers and overflow alarms, and efficient drift
eliminators) 
  

	3.	 ENERGY EFFICENCY

 Minimum Energy Performance 

Tenants are required to comply with the mandatory provisions and prescriptive requirements of the Massachusetts State Energy Stretch Code. In addition, Tenants
are required to provide the following energy conservation measures: 
  

	 	•	 	 achieving a connected lighting power density of 0.5 w/SF or better (easily achievable with LED lighting fixtures)



  

	 	•	 	 Vacancy and daylight controls as required by Code, and sensors for non-Code required spaces such as
electrical/Data closets, etc. 


  

	 	•	 	 Energy Star appliances for at least 50% of eligible equipment (by rated power). 



 

	 	•	 	 Consideration for advanced network lighting controls is recommended as it provides for users’
controllability features. 


  

	 	•	 	 Plug load management (controlled hard wired and electrical convenience outlets). 



 

	 	•	 	 Additional HVAC and plumbing equipment to meet or exceed the energy and water efficiency Code required criteria.



 Tenants occupying space in 321 Harrison Avenue will benefit from the energy efficiencies of the base building systems. 

Fundamental Refrigerant Management 
 Tenants are required
to purchase new HVAC equipment which contain no CFC-based refrigerants. 
 Measurement and Verification 

The building has one main utility electrical meter. Tenant Sub-metering is provided for each floor’s main electrical panel. The building HVAC Building
Management System has the capacity to monitor multiple set points for the tenant electrical usage for lighting, cooling and ventilation. Please refer to Appendix C for the tenant Measurement and Verification (M&V) plan. 

The building has a main utility natural gas meter and a main potable water meter. Water submetering at tenant space is by tenant. 

MATERIALS AND RESOURCES 
 Storage and Recyclables

 A recycling room of approximately 60 SF is provided on each floor for tenant collection of recyclable materials. In addition, space is allocated in
the building trash/loading area on the first floor for storage of recyclable materials for pickup. Transport of recyclables from the on-floor recycling rooms to the first-floor storage area is by tenant for full-floor tenants and by landlord on
multi-tenant floors. Tenants are required to institute policies for the collection of recyclable materials. Collection should include mixed paper, corrugated cardboard, glass, plastics, metals, batteries and electronic waste. Separation and/or
co-mingling of various types of recyclable materials shall be coordinated with landlord.

	5.	 INNOVATION IN DESIGN 



While no specific additional measures are required, the following best sustainable design practices are recommended: 

 

	 	•	 	 Establishing and maintaining a purchasing program to limit the amount of mercury containing lamps (overall
average of 35 picograms per lumen-hour). [Mostly achievable by maximizing the use of LED light fixtures] 


  

	 	•	 	 Provide a green cleaning program (may be provided by the building owner). 



 

	 	•	 	 Plug load management for hard wired and convenience electrical outlets, where a majority of 75% of the electrical
outlets are timed to turn off during unoccupied hours (and/or tied to vacancy sensors) 


  

	 	•	 	 Health & wellness strategies inspired from the WELL Building Standard (www.wellcertified.com)

The CMP shall include, without limitation, measures dealing with: proposed street occupancies; use of tower cranes; sidewalk occupancies or
obstruction of pedestrian flow; materials staging; transportation and parking for construction workers; hours of construction work; materials delivery. Key issues to be incorporated in the CMP include:

during construction. 


  

	 	•	 	 Frequency and schedule for truck movements and construction materials deliveries, including designated and
prohibited delivery times. 


  

	 	•	 	 Truck routing plan (including designated truck routes and sign plan). 



 

	 	•	 	 Construction staging and material handling. Staging areas to be coordinated with existing construction occurring

	 	•	 	 Plans for maintaining pedestrian and vehicle access during each phase of construction. 



 

	 	•	 	 Parking provisions for construction workers. 



 

	 	•	 	 Mode of transportation for construction workers, initiatives for reducing Driving and parking demand such as TDM
Measures as applied to construction workers. 


  

	 	•	 	 Coordination with other construction projects in the area. 



 

	 	•	 	 Distribution of information regarding construction conditions and impact mitigation to abutters. This includes
construction site signs. All construction sites shall include a sign that lists the name of the construction company (general contractor), their phone number, which is clearly visible to enable the public to call with any questions or concerns.



  

	 	•	 	 Costs. All construction costs are the responsibility of the developers. 



Failure to comply with the provisions of the CMP may result in withdrawal of the building permit or street occupancy permit until such time as
the Commissioner of BTD determines that the Developer is in compliance with the construction management plan.

 Appendix 2 

BTD Requirements for Implementation of Transportation System Improvements 

All transportation system improvements including, geometric changes, traffic signal changes and all elements of the design, construction and
inspection, will be carried out and fully funded by the Developer in close coordination with BTD. All work must meet BTD specifications and standards and must be performed by certified and licensed firms that meet BTD’s approval. BTD must
approve each step in the design and construction process. The Developer is responsible for obtaining all necessary permits and licenses. Once completed the improvements will be made available for BTD inspection. Based on inspection, the Developer
shall complete any outstanding items or repairs within 3 months of the inspection date. If the Developer is unable to meet these deadlines, the Developer shall notify BTD in writing to request an extension. Based on consultation with the Developer,
