THIS LEASE (this “Lease”) is entered into as of this 6th day of March,
2015 (the “Execution Date”), by and between BMR-MEDICAL CENTER DRIVE LLC, a Delaware limited liability company (“Landlord”), and REGENXBIO INC., a Delaware corporation (“Tenant”). 

RECITALS 
 A.
WHEREAS, Landlord owns certain real property (the “Property”) and the improvements on the Property located at 9704, 9708, 9712 and 9714 Medical Center Drive, Rockville, Maryland, including the buildings located thereon; and 

B. WHEREAS, Landlord wishes to lease to Tenant, and Tenant desires to lease from Landlord, certain premises (the “Premises”)
located on the first (1st) floor of the building at 9712 Medical Center Drive, Rockville, Maryland (the “Building”), pursuant to the terms and conditions of this Lease, as
detailed below. 
 AGREEMENT 

NOW, THEREFORE, Landlord and Tenant, in consideration of the mutual promises contained herein and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, agree as follows: 
 1. Lease of Premises. 

1.1. Effective on the Term Commencement Date (as defined below), Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the
Premises, as shown on Exhibit A attached hereto, for use by Tenant in accordance with the Permitted Use (as defined below) and no other uses. The Property and all landscaping, parking facilities, private drives and other improvements and
appurtenances related thereto, including the Building and the buildings located at 9704, 9708 and 9714 Medical Center Drive, Rockville, Maryland, are hereinafter collectively referred to as the “Project.” The Building is located on
a portion of the Project commonly referred to as the “South Campus,” which is that part of the Project comprised of the Building and two (2) other buildings located at 9708 and 9714 Medical Center Drive, Rockville, Maryland, together
with all appurtenances thereto (collectively, the “South Campus”). All portions of the Building that are for the non-exclusive use of the tenants of the Building only, and not the tenants of the Project generally, such as service
corridors, stairways, elevators, public restrooms and public lobbies (all to the extent located in the Building), are hereinafter referred to as “Building Common Area.” All portions of the Project that are for the non-exclusive use
of tenants of the South Campus or the Project (as applicable) generally, including driveways, sidewalks, parking areas, landscaped areas, and service corridors, stairways, elevators, public restrooms, public lobbies and the Amenities Area (as
defined below) (but excluding Building Common Area), are hereinafter referred to as “Project Common Area.” The Building Common Area and Project Common Area are collectively referred to herein as “Common Area.” 







 1.2. There currently exists an amenities area located in the amenities level of the building at
9714 Medical Center Drive, Rockville, Maryland, which consists of a fitness center, kitchenette, bathrooms, locker room, board room, and assembly area (collectively, the “Amenities Area”). The Amenities Area is currently for the use
of the tenants of the South Campus only; provided, however, that Landlord reserves the right to allow the tenants of the entire Project to use the Amenities Area.

 3. Term. The actual term of 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 actual Term Commencement Date (as defined in Article 4) and end on the date that is sixty-six (66) months after the actual
Term Commencement Date (such date, the “Term Expiration Date”), subject to extension or earlier termination of this Lease as provided herein, provided that if the actual Term Commencement Date is not the first day of a calendar
month, the Term and the Term Expiration Date shall be extended to the last day of the calendar month in which the Term Expiration Date would otherwise occur (and Base Rent for such extension period shall be payable at the rate in effect during the
month immediately preceding such extension period). 
 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 on Exhibit B 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. The term “Substantially Complete” or “Substantial Completion” means that (y) the 

  
 4 








 
Tenant Improvements are substantially complete in accordance with the plans attached hereto as Exhibit B (the “Tenant Improvement Plans”), except for minor punch list
items and (z) a certificate of occupancy has been issued for the Premises. Notwithstanding anything in this Lease 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). 
 4.2. The “Term Commencement Date” shall be the day
Landlord tenders possession of the Premises to Tenant with the Tenant Improvements Substantially Complete. If possession is delayed by action of Tenant, then the Term Commencement Date shall be the date that the Term Commencement Date would have
occurred but for such delay. Tenant shall execute and deliver to Landlord written acknowledgment of the actual Term Commencement Date and the Term Expiration Date within ten (10) business days after Tenant takes occupancy 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. 

4.3. Landlord shall permit Tenant and its contractors to enter upon the Premises, commencing upon the date that Landlord reasonably estimates
to be thirty (30) days prior to the Term Commencement Date, for the purpose of installing therein improvements, cabling, equipment, furniture and personal property, provided that Tenant shall furnish to Landlord evidence satisfactory to
Landlord in advance that insurance coverages required of Tenant and its contractors 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 or Tenant’s Adjusted Share of Operating Expenses (as defined below); 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 delay. 
 4.4. Landlord shall cause the Tenant Improvements to be constructed in the
Premises at Landlord’s sole cost and expense. All costs incurred by Landlord in connection with the Tenant Improvements including, without limitation, costs of (a) construction, (b) commissioning of mechanical, electrical and plumbing
systems by a licensed, qualified commissioning agent hired by Landlord, (c) space planning, architect, engineering and other related services, (d) 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 (e) fees, costs and expenses for Landlord’s architect, and engineer, labor, material, equipment and fixtures shall be referred to in this Lease as the
“Tenant Improvement Costs.” In the event that Tenant fails to comply with any of its obligations under this Lease and such failure causes Landlord to incur additional Tenant Improvement Costs, Tenant shall pay to Landlord as
Additional Rent (as defined below) the amount of any such additional costs within thirty (30) days of receiving an invoice from Landlord. Landlord shall construct the Tenant Improvements in a good and workmanlike manner and in compliance with
all Applicable Laws and the Tenant Improvement Plans. 
 4.5. Any changes to the Tenant Improvement Plans requested by Tenant (each, a
“Tenant Change”) shall be requested and instituted in accordance with the provisions of this Section 4.5 and shall be subject to the written approval of Landlord as provided herein. 

  
 5 








 4.5.1 Tenant may request Tenant Changes by notifying Landlord in writing in substantially the
same form as the AIA standard change order form (a “Tenant Change Request”), which Tenant Change Request shall detail the nature and extent of any requested Tenant Changes. 

4.5.2 All Tenant Change Requests shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably
withheld, conditioned or delayed (provided, however, that, in the event any Tenant Change would, in Landlord’s reasonable judgment, delay the Substantial Completion of the Tenant Improvements, Landlord may withhold its approval with
respect thereto in its sole and absolute discretion). Landlord shall have five (5) days after receipt of a Tenant Change Request to notify Tenant in writing of Landlord’s approval or rejection of the Tenant Change and any rejection shall
state the reasons therefor in reasonable detail. Landlord’s failure to respond within such five (5) day period shall be deemed approval by Landlord. 

4.5.3 Notwithstanding anything to the contrary in this Lease, Tenant shall be solely responsible for all costs and expenses related to any
Tenant Changes (including, without limitation, costs of project management by Landlord (which fee shall equal three percent (3%) of the cost of the Tenant Change)). Tenant shall, within thirty (30) days of receiving an invoice therefore,
pay to Landlord the amount of any such costs. 
 4.5.4 Notwithstanding anything to the contrary in this Lease, in the event that any Tenant
Change causes a delay in the Substantial Completion of the Tenant Improvements, the Term Commencement Date shall be the date that the Term Commencement Date would have occurred but for such delay. 

4.5.5 The Tenant Improvement Plans shall be automatically updated to include any Tenant Changes approved by Landlord in accordance with this
Section 4.5. 
 4.6. Landlord shall be permitted to make changes to the Tenant Improvement Plans (each, a “Landlord
Change”) subject to the terms, conditions and provisions of this Section 4.6. Landlord shall be solely responsible for all costs and expenses related to any Landlord Changes. 

4.6.1 Landlord may request Landlord Changes by notifying Tenant in writing in substantially the same form as the AIA standard change order
form (a “Landlord Change Request”), which Landlord Change Request shall detail the nature and extent of any requested Landlord Changes. 

4.6.2 Subject to Subsection 4.6.3, all Landlord Change Requests other than Landlord Permitted Changes (as defined below), shall be
subject to Tenant’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed. Tenant shall have five (5) days after receipt of a Landlord Change Request to notify Landlord in writing of
Tenant’s approval or rejection of the Landlord Change. Tenant’s failure to respond within such five (5) day period shall be deemed approval by Tenant. 

  
 6 








 4.6.3 Notwithstanding anything to the contrary in this Lease, Landlord shall be permitted to make
Landlord Permitted Changes (as defined below) without obtaining Tenant’s consent but with prior written notice to Tenant in the event of a Landlord Permitted Change under Subsection (b) below. “Landlord Permitted
Changes” shall mean (a) minor changes (such as slight relocation of switches and/or outlets) to accommodate unforeseen field conditions and (b) changes required by Applicable Laws or by a Governmental Authority. 

4.6.4 The Tenant Improvement Plans shall be automatically updated to include any Landlord Permitted Changes or other Landlord Changes approved
by Tenant in accordance with this Section 4.6. 
 4.7. Notwithstanding anything to the contrary in this Lease, if Substantial
Completion has not occurred by the date that is ninety (90) days after the Estimated Term Commencement Date (such date, the “Abatement Date”’), then Tenant shall be entitled to receive one (1) day of Base Rent
abatement for each day thereafter that Substantial Completion has not occurred with such Base Rent abatement commencing on the first day of the seventh (7) month of the Term; provided, however, that the Abatement Date shall be subject to
extension on a day-for-day basis as a result of any delays in Substantial Completion to the extent actually caused by (a) Force Majeure, (b) Tenant Changes or (c) Tenant. 

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, except as otherwise expressly set forth
in this Lease, (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 with respect to the Tenant Improvements. Notwithstanding the foregoing, Landlord agrees that, as of the Term Commencement
Date, (x) the Premises shall be clean and free of debris and the prior tenant’s personal property and shall not contain any Hazardous Materials in violation of Applicable Laws, (y) the Premises and the Tenant Improvements shall be in
compliance with all Applicable Laws including, without limitation, the ADA (as defined below) (provided, however, that if Landlord fails to so deliver the Premises and the Tenant Improvements in compliance with the ADA and Applicable Laws,
then Tenant’s sole and exclusive remedy shall be to deliver written notice to Landlord detailing the nature of such failure and, upon receipt of any such notice, Landlord shall (at its sole cost and expense) promptly make any modifications
reasonably necessary correct such failure), and (c) the heating, ventilating and air conditioning (“HVAC”); mechanical; electrical; life safety and plumbing systems serving the Premises (such systems, collectively, the
“Building Systems”) shall be in good working condition, operating as designed and suitable for office use (and Landlord shall, at Landlord’s sole cost and expense, repair any latent defects in the Building Systems to the extent
that Tenant notifies Landlord of such latent defects on or before the date that is six (6) months after the Term Commencement Date). Tenant’s taking of possession of the Premises shall, except as otherwise agreed to in writing by Landlord
and Tenant, conclusively establish that the Premises, the Building and the Project were at such time in good, sanitary and satisfactory condition and repair; provided, however, that 

  
 7 








 
nothing in this grammatical sentence shall take away from Landlord’s express obligations under this Lease, including, without limitation, Landlord’s repair, maintenance, restoration and
legal compliance obligations expressly set forth in this Lease. 
 6. Rentable Area. 

6.1. The term “Rentable Area” shall reflect such areas as reasonably calculated by Landlord’s architect, 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 be deemed to have increased unless due to a physical change in the size of the Premises. 
 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 South Campus is the total Rentable Area of all buildings within the South Campus. 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 (but no more often than annually), 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. 
 7. Rent. 

7.1. Tenant shall pay to Landlord as Base Rent for the Premises, commencing on the Term Commencement Date, the sums set forth in
Section 2.3. Base Rent shall be paid in equal monthly installments as set forth in Section 2.3, each in advance on the first day of each and every calendar month during the Term. 

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 Pro Rata Share of Building, South Campus or Project (as applicable) of any increases in (i) Real Estate Taxes (as defined below) over Real Estate Taxes for the 2015 calendar year (the “Base
Year”) and (ii) 

  
 8 








 
Operating Expenses (as defined below) over Operating Expenses for the Base Year, (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 (except as otherwise expressly provided in this Lease), in lawful money of the United States of America
pursuant to the address as 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 on a day other than the first day of a calendar month or
ends on a day other than the last day of a calendar month, then the Rent for such fraction of a calendar month shall be prorated for such period on the basis of the number of days in the calendar month and shall be paid at the then-current rate for
such fractional calendar month. 
 7.4. Except as otherwise expressly provided in this Lease, 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) any casualty or taking or (d) any other occurrence; and, except as
otherwise expressly provided in this Lease, 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. [Intentionally omitted] 
 9. Operating
Expenses. 
 9.1. As used herein, the term “Operating Expenses” shall include (subject to the exclusions set forth in
Section 9.1(c)): 
 (a) Government impositions, including property tax costs consisting of real and personal property taxes
(including amounts due under any improvement bond upon the Building or the Project (including the parcel or parcels of real property upon which the Building, the other buildings in the Project and areas serving the Building and the Project are

or maintenance of the Building and the Project (including the Amenities Area), and costs of repairs and replacements to improvements within the Project as appropriate to maintain the Project as required hereunder; costs of utilities furnished to the

(c) Notwithstanding the foregoing, Operating Expenses shall not include any net income, franchise, capital stock, estate or inheritance taxes,

of Landlord’s late payment of any Operating Expense; any leasing commissions, legal fees, and advertising costs incurred in connection with leasing of space in the Project; expenses that
relate to preparation, renovating or otherwise demolishing, modifying, improving, decorating, fixturing, furnishing, painting or altering of rental space for a tenant; expenses of initial development and construction or expansion of the Project,
including grading, paving, landscaping and decorating (as distinguished from maintenance, repair and replacement of the foregoing); legal expenses relating to disputes with tenants; costs of repairs to the extent reimbursed by payment of insurance
proceeds received by Landlord or pursuant to a warranty held by Landlord; payments of principal or interest upon loans to Landlord or secured by a mortgage or deed of trust covering the Project or a portion thereof (provided that interest
upon a government assessment or improvement bond payable in installments shall be included in Real Estate Taxes as provided in Subsection 9.1(a)); ground and/or underlying lease payments; salaries of executive officers of Landlord or any
employee of Landlord above the level of the acting property manager of the Project; Landlord’s general overhead and administrative expenses; 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); points,
commissions, closing costs, legal fees, costs or expenses incurred in connection with the financing or sale of the Project or any portion thereof; 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; charitable or
political contributions and/or trade association dues; asset management fees and property management fees of any property management firm based on a rate to the extent in excess of the rate of such fees paid by Landlord with respect to the Base Year
(provided, however, that nothing in this Section 9.1 shall take away from Tenant’s obligation to pay the Property Management Fee as required under Section 9.2 of this Lease); moving expense costs of tenants or
occupants of the Project; reserves for future Operating Expenses; 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 any increase in Operating Expenses over Operating Expenses for the Base Year (such
excess, together with Tenant’s Pro Rata Share of any increase in Operating Expenses over Operating Expenses for the Base Year, “Tenant’s Adjusted Share”). 

9.2. Tenant shall pay to Landlord on the first day of each calendar month of the Term, as Additional Rent, (a) commencing on the Term
Commencement Date, the Property Management Fee (as defined below), (b) commencing on January 1, 2016, Landlord’s good faith estimate of Tenant’s Adjusted Share of any increase of Operating Expenses over the Base Year with respect
to the Building, the South Campus and the Project, as applicable, for such month and (c) commencing on January 1, 2016, Landlord’s good faith estimate of Tenant’s Pro Rata Share of any increase of Real Estate Taxes over the Base
Year with respect to the Building, South Campus and the Project, as applicable, for such month. 

  
 11 








 (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 thereof 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. For the first six (6) months of the Term, the Property Management Fee shall be calculated as if Tenant were paying Twenty-Three Thousand Nine
Hundred Twenty-Two and 88/100 Dollars ($23,922.88) per month for Base Rent. 
 (x) Within ninety (90) days (or such longer period as
may be reasonably required by Landlord) after the conclusion of each calendar year (commencing with calendar year 2016), Landlord shall furnish to Tenant a statement showing in reasonable detail the actual Operating Expenses for the previous
calendar year and the Base Year, and Tenant’s Adjusted Share of any increase in Operating Expenses for the previous calendar year over the Base Year (“Landlord’s Statement”). Any additional sum due from Tenant to Landlord
shall be due and payable within thirty (30) days after Tenant’s receipt of Landlord’s Statement. If the amounts paid by Tenant pursuant to this Section exceed Tenant’s Adjusted Share of any increase in Operating Expenses for the
previous calendar year over the Base 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) Landlord’s good faith estimate of Tenant’s Pro Rata Share of any increase in
Real Estate Taxes for the upcoming calendar year over the Base Year shall be completed in good faith by Landlord at the end of each calendar year and thereafter be payable to Landlord in equal estimated monthly installments as provided in
Section 9.2, subject to readjustment when the actual amount of Real Estate Taxes is determined. After readjustment, any shortage shall be due and payable by Tenant within thirty (30) days after Tenant’s receipt of
Landlord’s readjustment statement, and any overpayment by Tenant shall be credited by Landlord against the Rent next due and owing from Tenant; provided that, if the Term has expired, Landlord shall accompany any such statement of
readjustment with payment for the amount of such overpayment. If the taxing authority provides an estimated tax bill, then monthly installments of Real Estate Taxes shall be based thereon until the final bill is ascertained. Landlord shall furnish
to Tenant, upon Tenant’s request, but not more than once in any calendar year, a copy of the tax bill and/or any estimated tax bill for the Project. 

(z) 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 may, from time to time, modify Landlord’s calculation and allocation procedures
for Operating Expenses, so long as such modifications produce Dollar results substantially consistent with (i) Landlord’s then-current reasonable management practices at the Project, and (ii) the requirements of this Article 9.
Since the Project consists of multiple buildings, certain Operating Expenses may pertain to a particular building, certain Operating Expenses may pertain to the South Campus, and other Operating Expenses to the Project as a


  
 12 








 
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, any costs applicable to the South
Campus to the buildings comprising the South Campus (including the 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. Tenant shall not be responsible for Real Estate Taxes or Operating Expenses with respect to any time period prior
to the Term Commencement Date. Tenant’s responsibility for Tenant’s Adjusted Share of Operating Expenses and Tenant’s Pro Rata Share of Real Estate Taxes 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. 

9.5. Real Estate Taxes and 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 Real Estate Taxes and Operating Expenses. 

9.6. In the event that the Building, South Campus 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, South Campus or Project, as applicable, to equal Landlord’s reasonable estimate of what such Operating Expenses would have been had the Building,
South Campus 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 pay prior to delinquency any and all taxes levied against any personal property or trade fixtures placed by Tenant in or
about the Premises or on any gross or net receipts of or sales by Tenant. 
 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, within thirty (30) days after written demand
(accompanied by reasonable supporting documentation thereof), repay to Landlord the taxes so paid by Landlord. 

  
 13 








 10.3. If any improvements in or alterations to the Premises (excluding the initial Tenant
Improvements), 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 during the period commencing on the Execution Date and ending upon the expiration or termination of Tenant’s obligations under this Lease. 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 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 may 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. If Tenant shall fully and faithfully perform every provision of this Lease to be performed by it, 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 thirty (30) days after the expiration or earlier termination of this Lease. 

11.5. [Intentionally omitted] 

  
 14 








 11.6. 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. 

11.7. 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 six (6) 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” shall mean 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, 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 refund 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 forty-five (45) 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) six (6) months after the


  
 15 








 
then-current Term Expiration Date or (2) the date 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 ten (10) 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. 
 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. 
 12.2. Tenant shall not use or occupy the Premises in violation of Applicable Laws; zoning ordinances; or the
certificate of occupancy issued for the Building or the Project, and shall, upon five (5) business 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 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. 

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, within thirty
(30) days after written demand (accompanied by reasonable supporting documentation thereof), reimburse 

  
 16 








 
Landlord for any additional premium charged for such policy by reason of Tenant’s failure to comply with the provisions of this Article. 

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, not to be unreasonably withheld, conditioned or delayed. 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
reasonably deem it necessary to make such change. Landlord shall provide Tenant with forty (40) access cards to the Building at no additional cost. 

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 without Landlord’s prior written consent. 
 12.7. Subject to compliance with all Applicable
Laws, Tenant shall have the right to install and maintain, at Tenant’s sole cost and expense, one (1) exterior sign on the exterior of the Building identifying Tenant (“Exterior Signage”). The size, color, type and
location of Exterior Signage shall be subject to Landlord’s reasonable approval. No sign, advertisement or notice (including the Exterior Signage, “Signage”) shall be exhibited, painted or affixed by Tenant on any part of the
Premises, which Signage is visible from outside the Premises, or the Building without Landlord’s prior written consent, which consent shall not be unreasonably withheld. Signage (other than within the Premises which is not visible from outside
the Premises) shall conform to Landlord’s standard design criteria. 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. Prior to the expiration or earlier termination of this Lease, Tenant shall remove Exterior Signage at Tenant’s sole cost and expense, and Tenant shall reimburse Landlord
for costs incurred by Landlord in removing any of Tenant’s Signage upon the expiration or earlier termination of the Lease. Initial 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 Building-standard size, color and type and be located in a place reasonably 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. At Landlord’s option, Landlord may install any Tenant Signage, and
Tenant shall pay all reasonable out-of-

  
 17 








 
pocket costs (without mark-up, overhead or profit) associated with such installation within thirty (30) days after demand therefor (accompanied by reasonable supporting documentation
thereof). The right to install Exterior Signage is personal to REGENXBIO Inc., and may not be exercised by any assignee, sublessee or transferee of this Lease, except to Tenant’s Affiliate subsequent to an Exempt Transfer (as defined below). If
Landlord elects, in Landlord’s sole and absolute discretion, to make monument Signage available to all tenants of the Project, then Landlord shall make a portion of such monument Signage (with the size and location of such portion to be
determined by Landlord in Landlord’s sole and absolute discretion) available to Tenant for purposes of installing and maintaining Signage identifying Tenant (which Signage shall be installed, maintained and removed at Tenant’s sole cost
and expense and otherwise in accordance with all of the terms, conditions and provisions of this Section). 
 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 areas 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 or annoy them, (b) use or allow the Premises to be used for immoral,
unlawful or objectionable 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. 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. 

12.11. Notwithstanding any other provision herein to the contrary (but subject to Landlord’s obligations in Section 5(y)
above), Tenant shall be responsible for all liabilities, costs and expenses arising out of or in connection with the compliance of the Premises 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, save, defend (at Landlord’s option and with counsel reasonably
acceptable to Landlord) and hold 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 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 

  
 18 








 
or dismissed) incurred in investigating or resisting the same (collectively, “Claims”) arising out of any such failure of the Premises to comply with the ADA. For the avoidance
of doubt, “Lenders” shall also include historic tax credit investors and new market tax credit investors. The provisions of this Section shall survive the expiration or earlier termination of this Lease. 

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”); provided, however, that such other rules and regulations shall not be binding
upon Tenant until Tenant has received a written copy thereof and provided further that any such other rules and regulations shall not materially modify Tenant’s rights or obligations hereunder. 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. In the event of a conflict or any inconsistency between the Rules and Regulations and the Lease, the Lease shall prevail. 

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 that any such amendments, restatements, supplements or modifications do not materially modify Tenant’s rights or
obligations hereunder. Tenant shall comply with the CC&Rs. 
 13.3. Tenant shall have a non-exclusive, irrevocable license to use
Tenant’s Pro Rata Share of parking facilities serving the Project in common on an unreserved basis with other tenants of the Project during the Term at no additional cost. As of the Execution Date, Tenant’s Pro Rata Share of the parking
facilities described above is equal to two point six (2.6) parking spaces per one thousand (1,000) square feet of Rentable Area of the Premises. 

13.4. Tenant agrees not to unreasonably overburden the parking facilities serving the Project and agrees to reasonably cooperate with Landlord
and other tenants in the use of the parking facilities. 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. 

14. Project Control by Landlord. 
 14.1.
Landlord reserves full control over the Building and the Project to the extent not inconsistent with (a) Tenant’s enjoyment of the Premises as provided by this Lease, (b) Tenant’s rights under this Lease or
(c) Landlord’s obligations under this Lease. This reservation includes Landlord’s right to subdivide the Project; convert the Building and other buildings within the 

  
 19 








 
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 pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises (provided that such installation, use, maintenance, repair, replacement or relocation
does not materially reduce the useable area of the Premises), the Building or elsewhere at the Project; access areas of the Premises necessary for utilities, services, safety and operation of the Building; and alter or relocate any other Common Area
or facility, including private drives, lobbies, entrances and landscaping; provided, however, that any entry into the Premises shall be subject to the provisions of Section 14.4 of this Lease, and 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. 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. 
 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 or obligations for Tenant or that deprives Tenant of any rights (including, without limitation, the quiet enjoyment and use of, and access to, the Premises) as provided for in this Lease. 

14.4. Landlord may, at any and all reasonable times during non-business hours (or during 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 (t) exercise its
rights under Sections 14.1 and 21.4, (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 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 nine (9) months of the Term and current and prospective purchasers and lenders at any time. 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 to the extent and for the time 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; 

  
 20 








 
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 or interference by Landlord or persons claiming by, through or 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. Landlord shall pay for all water (from a local municipal or similar source), gas and electricity
supplied to the Premises, and Landlord shall be entitled to include these sums in Operating Expenses (provided, however, that utility costs attributable to the Supplemental HVAC Unit (as defined below) shall be paid by Tenant in accordance
with Section 16.11 below). Landlord may base its bills for utilities on reasonable estimates; provided that Landlord adjusts such billings promptly thereafter or as part of the next Landlord’s Statement 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, South Campus 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, South Campus or Project (as
applicable) to equal Landlord’s reasonable estimate of what such utility usage would have been had the Building, South Campus 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. Tenant shall not be liable for the cost of utilities supplied to the Premises attributable to the time period prior to the Term
Commencement Date; provided, however, that, if Landlord shall permit Tenant possession of the Premises prior to the Term Commencement Date and Tenant uses the Premises for any purpose other than placement of cabling, equipment, furniture and
personal property as set forth in Section 4.3, then Tenant shall be responsible for the cost of utilities supplied to the Premises from such earlier date of possession. 

16.2. 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 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; shortages of materials (which shortages are not unique to the party claiming Force Majeure); government regulations, moratoria or other governmental actions,


  
 21 








 
inactions or delays; 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 (collectively, “Force Majeure”); 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.
“Severe Weather Conditions” means weather conditions that are materially worse than those that reasonably would be anticipated for the Property at the applicable time based on historic meteorological records. Notwithstanding
anything to the contrary in this Lease, if, for more than ten (10) 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 in whole or in part by the action or inaction of a Tenant Party (as defined below)), the provision of Base HVAC (as defined below) 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 Tenant’s Base Rent and Tenant’s obligations under this Lease to pay Real Estate Taxes and 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 obligations under this Lease to pay Real Estate Taxes and 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 Base HVAC and other utilities and Landlord provides substitute Base HVAC and
other utilities reasonably suitable for Tenant’s continued use and occupancy of the Premises for the Permitted Use (e.g., supplying portable air conditioning equipment), then neither Base Rent nor Tenant’s obligations under this Lease to
pay Real Estate Taxes and 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 Base HVAC or other utilities that Landlord must provide
pursuant to this Lease, regardless of the cause, Landlord shall diligently pursue the restoration of such Base 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 Base HVAC or other utilities to the Premises. 

16.3. 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 other telecommunications and other
utilities 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.
If any such utility for which Tenant is responsible is not separately metered to Tenant, Tenant shall pay, no more often than monthly, Tenant’s Adjusted Share of all charges of such utility (at the rate charged to the Project by the utility
provider, without markup, overhead or profit) jointly metered with other premises as Additional Rent (outside of Operating Expenses within thirty (30) days of receiving an 

  
 22 








 
invoice from Landlord) or, in the alternative, Landlord may, at its option, and sole cost (outside of Operating Expenses), meter the usage of such utilities by Tenant, and Tenant shall pay, no
more often than monthly, all charges of such utility (at the rate charged to the Project by the utility provider, without mark-up, overhead or profit) as Additional Rent (outside of Operating Expenses within thirty (30) days of receiving an
invoice from Landlord). 
 16.4. 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. 
 16.5. If Tenant shall require utilities or services materially 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. 

16.6. Landlord shall provide 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 reasonably determines that Tenant requires, uses or consumes water provided to the Common Area for any purpose other than ordinary lavatory purposes, and such additional requirement, use or
consumption is not promptly discontinued after written demand from Landlord, 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. 
 16.7. Landlord reserves the right to stop service of the elevator,
plumbing, ventilation, air conditioning and utility systems, when Landlord reasonably deems necessary, due to accident, emergency 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 16.2, 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 or, to the extent permitted by Applicable Laws, Landlord’s 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 

  
 23 








 
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. 

16.8. Landlord shall provide janitorial and cleaning services to the Premises meeting the specifications attached hereto as
Exhibit K, Monday through Friday excluding holidays recognized as such by the federal government and/or the State of Maryland. 

16.9. For the Premises, Landlord shall (a) maintain and operate the HVAC systems serving the Premises (excluding the Supplemental HVAC
Unit) used for the Permitted Use only (“Base HVAC”) and (b) subject to Subsection 16.9(a), furnish Base 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;
provided that Tenant complies with the next sentence. If Tenant will require Base HVAC outside normal business hours of business days (defined as Monday through Friday from 8:00 a.m. until 6:00 p.m. and Saturday from 8:00 a.m. until 12:00
p.m.) in the Premises (“Overtime HVAC”), then Landlord shall be obligated to provide Overtime HVAC only if Tenant (y) requests it by 4 p.m. on the immediately preceding business day and (z) requires a minimum of at least
two (2) hours of Overtime HVAC. Tenant shall pay Landlord, as Additional Rent, one hundred percent (100%) of Landlord’s actual total cost of delivering steam and chilled water for Overtime HVAC for the Premises, the rate of which is
currently Fifty Dollars ($50.00) per hour. Notwithstanding anything to the contrary in this Section (but subject to Section 16.2 above), Landlord shall have no liability, and Tenant shall have no right or remedy, on account of any
interruption or impairment in Base HVAC services; provided that Landlord diligently endeavors to cure any such interruption or impairment. 

16.10. For any utilities serving the Premises for which Tenant is billed directly by such utility provider, Tenant agrees to furnish to
Landlord, within thirty (30) days after Landlord’s request, (a) any invoices or statements for such utilities, (b) any other utility usage information reasonably requested by Landlord, and (c) authorization to allow Landlord
to access Tenant’s usage information reasonably available and reasonably necessary for Landlord to complete an ENERGY STAR® Statement of Performance (or similar comprehensive utility
usage report, if requested by Landlord) and any other reasonably available information as 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 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. 

16.11. Notwithstanding anything to the contrary in this Lease, any supplemental HVAC unit servicing the Premises (the “Supplemental
HVAC Unit”) shall be the sole responsibility of 

  
 24 








 
Tenant and Landlord shall have no obligations with respect thereto. Tenant shall, at its sole cost and expense, maintain and keep the Supplemental HVAC Unit in good condition and repair and shall
otherwise be solely responsible for any repair, maintenance and/or replacement costs with respect to the Supplemental HVAC Unit. Tenant shall keep in full force and effect during the Term (and occupancy by Tenant, if any, after termination of this
Lease) a preventative maintenance contract for quarterly, semi-annual, and annual Supplemental HVAC Unit inspections and maintenance using a qualified, licensed, bonded service provider reasonably approved by Landlord. If requested in writing by
Landlord, Tenant shall provide to Landlord copies of the Supplemental HVAC Unit maintenance contracts and the Supplemental HVAC Unit maintenance reports on a quarterly basis. In the event Landlord determines that Tenant is not properly maintaining
the Supplemental HVAC Unit, Landlord may take over Tenant’s responsibilities with respect to the Supplemental HVAC Unit. Any such costs or expenses incurred, or payments made by Landlord as a result of Tenant failing to properly maintain the
Supplemental HVAC Unit, shall be deemed to be Additional Rent payable by Tenant outside of Operating Expenses within thirty (30) days of receiving an invoice therefor. Notwithstanding anything to the contrary in this Lease, commencing on the
Term Commencement Date and continuing throughout the Term, Tenant shall pay to Landlord (as Additional Rent outside of Operating Expenses within thirty (30) days of receiving an invoice therefor) all utility charges in connection with the
Supplemental HVAC Unit. Tenant shall pay to Landlord (as Additional Rent outside of Operating Expenses within thirty (30) days of receiving an invoice therefor) an amount equal to all costs paid or incurred by Landlord in connection with
purchasing, installing and monitoring any metering equipment Landlord deems reasonably necessary to monitor utility consumption with respect to the Supplemental HVAC Unit. Upon Landlord’s demand, utility charges in connection with the
Supplemental HVAC Unit (if separately metered) shall be paid by Tenant directly to the supplier of such utilities. Notwithstanding anything to the contrary in this Lease, Landlord shall have no liability, and Tenant shall have no right or remedy, on
account of any interruption or impairment with respect to the Supplemental HVAC Unit. 
 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. Tenant shall, in making any Alterations, use only those architects, contractors, suppliers and mechanics of which Landlord has given prior written approval, which approval shall not be unreasonably
withheld, conditioned or delayed. In seeking Landlord’s approval, Tenant shall provide Landlord, at least twenty (20) days in advance 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, 

  
 25 








 
requests for laydown areas and such other information concerning the nature and cost of the Alterations as Landlord may reasonably request. 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, and Tenant agrees to comply with all reasonable requirements of Landlord relative to union and
non-union labor. 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 Forty Thousand Dollars ($40,000) annually, (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 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. 

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 reasonably designate, provided that except for noisy or disruptive work (as reasonably determined by Landlord), all such work may be performed
during normal business hours. 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, and to
the extent applicable (as reasonably determined by Landlord), 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 third-party commissioning agent hired by Tenant and reasonably 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 twenty (20) days’ prior written notice of
the proposed commencement of such work and shall, if required by Landlord, secure, at Tenant’s own cost and expense, a completion and lien indemnity bond satisfactory to Landlord for such work. 

17.6. Tenant shall repair any damage to the Premises caused by Tenant’s removal of any property from the Premises. During any such
restoration period extending after the expiration or earlier termination of the Term, Tenant shall pay Rent to Landlord as provided 

  
 26 








 
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, casework and related
appliances, trade fixtures, and 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; ductwork; conduits; electrical
panels and circuits; business and trade fixtures; attached machinery and equipment; and built-in furniture and cabinets, in each case, together with all additions and accessories thereto), shall (unless, prior to construction or installation
thereof, Landlord elects otherwise in writing) at all times remain the property of Landlord, shall remain in the Premises and shall (unless, prior to such construction or installation, 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, if any, 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. 

17.8. Notwithstanding any other provision of this Article to the contrary, in no event shall Tenant remove any improvement from the Premises
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. Landlord shall not require Tenant to remove any of
the initial Tenant Improvements. 
 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,
within thirty (30) days after written demand (accompanied by reasonable supporting documentation thereof), any costs and expenses incurred due to such removal and storage or Landlord may to the extent permitted by Applicable Laws, at its sole
option and without notice to Tenant, sell such property or any portion thereof at private sale 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. Tenant shall pay to Landlord as
Additional Rent an amount equal to three percent (3%) of the cost to Tenant of all Alterations to cover Landlord’s overhead and expenses for plan review, engineering review, coordination, scheduling and supervision thereof. For purposes of
payment of such sum, Tenant shall submit to Landlord copies of all bills, invoices and statements covering the costs of such charges, accompanied by payment to Landlord of the fee set forth in this Section. 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 caused by such 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 

  
 27 








 
documentation showing payment thereof and waiver of liens by all involved contractors, subcontractors and material suppliers, as 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 and all Landlord Parties (as
defined below) as additional insureds on their respective insurance policies. 
 18. Repairs and Maintenance. 

18.1. Landlord shall repair and maintain 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); HVAC systems (excluding the Supplemental HVAC Unit); elevators; and
electrical systems installed or furnished by Landlord. In addition, Landlord shall provide (a) janitorial services for the Premises comparable to the janitorial services provided by comparable owners of comparable properties in the Rockville,
Maryland, area, which services shall be provided five (5) nights per week, Monday through Friday, excluding holidays recognized as such by the federal government and/or the State of Maryland, and (b) Building standard lightbulb changes to
the Premises. 
 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 and every part thereof in good condition and repair, damage thereto from ordinary wear and tear excepted, 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 as good a condition as when received, ordinary wear and tear excepted; and
shall, at Landlord’s request and Tenant’s sole cost and expense, remove all telephone and data systems, wiring 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 as described in Exhibit B. 
 18.3.
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. 

18.4. 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 upon reasonable prior notice for the purpose of performing such work as such person shall reasonably deem necessary or desirable to preserve and protect the
Building from injury or damage and to support the same by proper foundations, 

  
 28 








 
without any claim for damages or liability against Landlord and without reducing or otherwise affecting Tenant’s obligations under this Lease; provided, however, that all such
activities shall be conducted only to the extent and for the time reasonably required and in such a manner so as to cause as little interference to Tenant as is reasonably possible. 

18.5. 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. 

18.6. Costs incurred by Landlord pursuant to this Article shall constitute Operating Expenses to the extent permitted by
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
out of 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) business days after 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 within five (5) days after written demand (accompanied by reasonable
supporting documentation) reimburse Landlord for the costs thereof as Additional Rent. Tenant shall indemnify, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord) and hold the Landlord Indemnitees harmless
from and against any Claims arising from any such liens, including any administrative, court or other legal proceedings related to such liens. 

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) business 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


  
 29 








 
(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) business 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 statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the Property. If Tenant fails to
deliver such statement within the prescribed time set forth in the first grammatical sentence of this Section, then Landlord shall deliver written notice to Tenant of such failure and if Tenant fails to deliver such statement within five
(5) days of receiving such written notice, Tenant’s failure to deliver such statement shall, at Landlord’s option, constitute a Default (as defined below) under this Lease. 

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 by Tenant or any of its employees, agents, contractors or invitees (collectively with Tenant,
each a “Tenant Party”), except for small amounts of Hazardous Materials included in typical office and cleaning supplies and equipment (provided that the same are stored, used and disposed of in accordance with Applicable Laws). 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 caused by a Tenant Party or
(ii) to the extent such contamination is caused by 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, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord) and hold the Landlord Indemnitees harmless 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 

  
 30 








 
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, condition or delay; 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. 

21.2. If (a) on the Execution Date, the Premises contains Hazardous Materials in violation of Applicable Laws, or (b) after the
Execution Date, Landlord causes the Premises to contain Hazardous Materials in violation of Applicable Laws, then Landlord shall cause such Hazardous Materials to be removed and/or abated in accordance with all Applicable Laws and in a manner which
minimizes disruption of Tenant’s access to and use and occupancy of the Premises, at no cost to Tenant (either directly or as an Operating Expense). 

21.3. [Intentionally omitted] 

21.4. At any time, and from time to time, prior to the expiration of the Term, Landlord shall, subject to the provisions of
Section 14.4 if entry into the Premises is required, 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 Section 21.1 of this Lease. 

21.5. [Intentionally omitted] 

21.6. Tenant shall promptly report to Landlord any actual or suspected presence of mold or water intrusion at the Premises. 

21.7. Landlord’s and 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 resulting from a violation of Tenant’s obligations under
Section 21.1 of this Lease, 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. 

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 

  
 31 








 
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. 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. 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
construction 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 reasonable determination, cause odors, fumes or exhaust. For
example, if Landlord reasonably 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. 

  
 32 








 23. Insurance; Waiver of Subrogation. 

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) or such lesser
coverage as Landlord may elect, provided that such coverage shall not be less than the amount of such insurance Landlord’s Lender, if any, requires Landlord to maintain, 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. 
 23.2. In addition, Landlord shall carry
Commercial General Liability insurance with limits of not less than One Million Dollars ($1,000,000) per occurrence/general aggregate for bodily injury (including death), or property damage with respect to the Project. 

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, $2,000,000 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, including those owned, hired
or otherwise operated or used by or on behalf of the Tenant. The coverage shall be on a broad-based occurrence form with combined single limits of not less than $1,000,000 per accident for bodily injury and property damage. 

(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 

  
 33 








 
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 plus twelve (12) months’ extended period of
indemnity. 
 (d) Workers’ Compensation insurance as is required by statute or law, or as may be available on a voluntary basis and
Employers’ Liability insurance with limits of not less than the following: each accident, Five Hundred Thousand Dollars ($500,000); disease ($500,000); disease (each employee), Five Hundred Thousand Dollars ($500,000). 

(e) [Intentionally omitted] 

(f) [Intentionally omitted] 

(g) During all construction by Tenant at the Premises, with respect to tenant improvements being constructed (including any Alterations),
insurance required in Exhibit B-l must be in place. 
 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. No such policy shall be cancelable or subject to reduction of coverage or other modification or cancellation except after twenty
(20) 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, prior to the 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), following written notice to Tenant, 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 Landlord, BioMed Realty, L.P., and BioMed Realty Trust, Inc., and their respective officers, employees, agents,
general partners, members, subsidiaries, affiliates and Lenders (“Landlord Parties”) as additional insureds as respects liability arising from work or 

  
 34 








 
operations performed by or on behalf of Tenant, Tenant’s use or occupancy of Premises, and ownership, maintenance or use of vehicles by or on behalf of Tenant. 

23.4. In each instance where insurance is to name Landlord Parties as additional insureds, Tenant shall, upon Landlord’s written request,
also designate and furnish certificates evidencing such 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. 
 23.5. 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. 

23.6. Tenant and its 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 insurance, including any deductibles or self-insurance maintained thereunder. If necessary, Tenant agrees to endorse
the required insurance policies to permit waivers of subrogation as required hereunder and hold harmless and indemnify the Landlord Parties 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 insurers so permit. Any termination of such a waiver shall be by written notice to Landlord, containing a description of the circumstances hereinafter set forth in this Section. Tenant,
upon obtaining the policies of 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. Landlord and its insurers hereby waive any and all rights of recovery or subrogation against Tenant
with respect to any loss, damage, claims, suits or demands, howsoever caused, that are covered, or should have been covered, by valid and collectible insurance, including any deductibles or self-insurance maintained thereunder. If necessary,
Landlord agrees to endorse the required insurance policies to permit waivers of subrogation as required hereunder and hold harmless and indemnify Tenant 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 Landlord’s insurers so permit. Any termination of such a waiver shall be by written notice to Tenant, containing a description of the circumstances hereinafter set forth in this Section.
Landlord, upon obtaining the policies of 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 Landlord shall notify Tenant of such conditions. 

  
 35 








 23.7. 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 comparable new tenants within the Project. 

23.8. Any costs incurred by Landlord pursuant to this Article shall constitute a portion of Operating Expenses to the extent permitted under
Article 9. 
 23.9. The provisions of this Section shall survive the expiration or earlier termination of this Lease. 

24. Damage or Destruction. 
 24.1. In the
event of a partial destruction of (a) the Premises or (b) Common Area of the Building or the Project ((a) and (b) together, 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 (x) the damage thereto is such that the Affected Areas may be repaired, reconstructed or restored within a period of six (6) months from
the date of the happening of such casualty, (y) Landlord shall receive insurance proceeds 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) 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 twelve (12) months after the date of the Damage Repair Estimate, (b) subject to Section 24.6, the Affected Areas are not actually repaired, reconstructed and restored within eighteen (18) months after the
date of the Damage Repair Estimate, or (c) the damage and destruction occurs within the last twelve (12) months of the then-current Term, 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 Subsections 24.2(a) and (c), 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 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, 

  
 36 








 
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 proceeds of business
interruption or loss of rental income insurance actually received by Tenant with respect to the Premises. 
 24.6. Notwithstanding anything
to the contrary contained in this Article, 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 or delays caused by a 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. 
 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. 

  
 37 








 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 twenty-four (24) 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. 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. 

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 (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) 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. 

  
 38 








 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. 

25.5. 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. 

26. Surrender. 
 26.1. At least ten
(10) days prior to Tenant’s surrender of possession of any part of the Premises, Tenant shall conduct a site inspection with Landlord. 

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 and (b) any amounts for which Tenant would otherwise be liable under this Lease if the Lease were still in effect, including payments for 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 Rent in effect during the last thirty (30) days of the Term, 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 

  
 39 








 
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. 
 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, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord) and hold the
Landlord Indemnitees harmless from and against any and all Claims of any kind or nature, real or alleged, arising from 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 (a) the presence at or use or occupancy of the Premises or Project by a Tenant Party, (b) an act or omission on the part of any Tenant Party, (c) a breach or default by Tenant in the
performance of any of its obligations hereunder or (d) 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 directly caused by 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 23.6, 28.2 and 31.12, Landlord agrees to indemnify, save, defend (at Tenant’s option and with counsel reasonably acceptable to Tenant)
and hold the Tenant Parties harmless 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 directly arising out of 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 caused by 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 

  
 40 








 
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 out of 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. 

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 caused by 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. 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: (a) Tenant selling, hypothecating, assigning, pledging, encumbering or otherwise transferring this Lease or subletting the
Premises or (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). For purposes of the preceding sentence, “control” means
(a) owning (directly or indirectly) more than fifty percent (50%) of the stock or other equity interests of another person or (b) 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 any person that (i) 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, (ii) is the successor entity to Tenant by merger or
consolidation or (iii) acquires all or substantially all of Tenant’s ownership interests or assets (any such entity, a “Tenant’s Affiliate”); provided that Tenant shall notify Landlord in writing at least sixty
(60) days prior to the effectiveness of such Transfer to Tenant’s Affiliate (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 net worth and creditworthiness (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
and creditworthiness (as of both the Execution Date and the date of the Exempt Transfer) of the transferring Tenant. For purposes of Exempt Transfers, “control” requires both (a) owning (directly or indirectly) more than fifty percent
(50%) of the stock or other equity interests of another person and (b)

  
 41 








 
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 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. 

29.2. In the event Tenant desires to effect a Transfer, then, at least sixty (60) but not more than ninety (90) 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 concerning the character of the proposed
transferee, assignee or sublessee; the Transfer Date; current balance sheet for the Tenant and the proposed transferee, assignee or sublessee; the most recent two (2) years of 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; 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 (other than an Exempt Transfer), may give consideration
to (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 cancel this Lease. In no event shall Landlord be deemed to be unreasonable for declining to consent to a Transfer 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. 

  
 42 








 29.4. The following are conditions precedent to a Transfer or to Landlord considering a request
by Tenant to a Transfer: 
 (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 reasonably satisfactory to Landlord that the value of Landlord’s interest under this
Lease shall not be diminished or reduced by the proposed Transfer. Such evidence shall include 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 costs and expenses, including reasonable attorneys’ fees, charges and
disbursements 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 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, 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 

  
 43 








 
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; 

(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; and 
 (n) Tenant shall deliver to Landlord one executed copy of any and all written instruments evidencing or relating
to the Transfer. 
 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 be void and shall, at the option of Landlord, terminate this Lease. 
 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 or sublessee other than pursuant to an Exempt Transfer, then Landlord shall have the option, exercisable by giving notice to Tenant at any time within ten (10) 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 ten (10) 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. 

  
 44 








 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. 
 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. As of the Execution Date, there are no mortgages, deeds of trust or ground leases encumbering the Project. The automatic subordination to any future mortgage, deed of trust or lease provided for in this Section is expressly
conditioned upon the holder of such mortgage, deed of trust or lease, agreeing that as long as no Default occurs under this Lease, the holder of such mortgage, deed of trust or lease will not disturb Tenant’s rights of possession under this
Lease. 
 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 such mortgagee, beneficiary or landlord under a lease wherein
Landlord is tenant (each, a “Mortgagee”) so elects, however, this Lease shall be deemed prior in lien 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. For the avoidance of doubt, “Mortgagees” shall also include historic tax credit investors and new market tax credit investors. 

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 Mortgagee 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 

  
 45 








 
deed covering the Premises. Therefore, if any installment of Rent due from Tenant is not received by Landlord within five (5) 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) nine percent (9%) 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 seven (7) days after Landlord’s written 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. 

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. If a dispute shall arise as to any amount or sum of money to be paid by Tenant to Landlord hereunder, Tenant shall
have the right to make payment “under protest,” such payment shall not be regarded as a voluntary payment, and there shall survive the right on the part of Tenant to institute suit for recovery of the payment paid under protest. 

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 notice and 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; 

(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 five (5) days after written notice thereof from Landlord to Tenant; 

  
 46 








 (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 fifteen (15) 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 fifteen (15) days to cure, Tenant shall not be deemed to be in Default if Tenant commences such cure within such fifteen (15) day period and thereafter diligently
prosecutes the same to completion; and provided, further, that such cure is completed no later than thirty (30) 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; or 

(i) Tenant’s interest in this Lease is attached, executed upon or otherwise judicially seized and such action is not released 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 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: 

(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 

  
 47 








 
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 worth at the time of award of the amount by which the unpaid Rent that would have accrued during the period commencing with
termination of the Lease and ending at the time of award exceeds that portion of the loss of Landlord’s rental income from the Premises that Tenant proves to Landlord’s reasonable satisfaction could have been reasonably avoided; plus 

C. The worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds that
portion of the loss of Landlord’s rental income from the Premises that Tenant proves to Landlord’s reasonable satisfaction could have been reasonably avoided; plus 

D. Any other amount necessary to compensate Landlord for all the detriment caused by Tenant’s failure to perform its obligations under
this Lease or that in the ordinary course of things would be likely to result therefrom, including the cost of restoring the Premises to the condition required under the terms of this Lease, including any rent payments not otherwise chargeable to
Tenant (e.g., during any “free” rent period or rent holiday); plus 
 E. At Landlord’s election, such other amounts in
addition to or in lieu of the foregoing as may be permitted from time to time by Applicable Laws; or 
 (ii) At Landlord’s election,
as minimum liquidated damages in addition to any (A) amounts paid or payable to Landlord pursuant to Section 31.5(c)(i)(A) prior to such election and (B) costs of restoring the Premises to the condition required under the terms
of this Lease, an amount (the “Election Amount”) equal to either (Y) 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 

  
 48 








 
“Discount Rate”) or (Z) 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 Sections 31.5(c)(i)(A) and (B), “worth at the time of award” shall be computed by allowing interest at the
Default Rate. As used in Section 31.5(c)(i)(C), the “worth at the time of the award” shall be computed by taking the present value of such amount, using the Discount Rate. 

31.6. 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, unless or to the extent required by Applicable
Law. 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. 

31.7. If Landlord does not elect to terminate this Lease as provided in Section 31.5, 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. 

31.8. In the event Landlord elects to terminate this Lease and relet the Premises, Landlord may execute any new lease in its own name. Tenant
hereunder 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 

  
 49 








 
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. 

31.9. 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 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, unless or to the extent required by Applicable Law. Any obligation
imposed by Applicable Law 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 any
party 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. 

31.10. 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. 
 31.11. 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. 

31.12. 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, 

  
 50 








 
representations, warranties or promises hereunder, except as may otherwise be expressly set forth in this Lease. 

31.13. In the event of any default by Landlord, Tenant shall give notice by registered or certified mail or by a reputable international
overnight delivery service, such as FedEx, 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. 

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 Scheer Partners (“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 

  
 51 








 
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, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord) and hold the Landlord Indemnitees harmless 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. 
 33.5. Landlord 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 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 agrees to indemnify, save, defend (at Tenant’s option and with counsel reasonably acceptable to Tenant) and hold Tenant harmless from any and all cost or liability for compensation claimed by any broker or agent, other than
Broker, employed or engaged by Landlord or claiming to have been employed or engaged by Landlord. 
 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 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, (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 and/or (d) any
insurance proceeds or condemnation awards received by Landlord in connection with a casualty loss or condemnation of the Building or 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 

  
 52 








 
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, shall mean and include 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. 
 37. Representations. Tenant guarantees, warrants and represents that (a) Tenant is duly incorporated or otherwise

(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

(y) to a party’s attorneys, accountants, brokers and other bona fide consultants or advisers (with respect to this Lease only); provided such third parties agree to be bound by this Section or (z) to bona fide prospective

a reputable international overnight delivery service, such as FedEx, or (c) facsimile or email transmission, so long as such transmission is followed within one (1) business day by delivery utilizing one of the methods described in

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 promptly furnish to Landlord, from time to time, upon Landlord’s written request (but no more than one (1) time per calendar year), 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. 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.

 40.5. Landlord may, but shall not be obligated to, record a short form or memorandum hereof (at Landlord’s sole cost and expense)
without Tenant’s consent. Within ten (10) days after receipt of written request from Landlord, Tenant shall execute a termination of any short form or memorandum 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 section headings of this Lease are not a part 

  
 55 








 
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 out of 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). 

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. Whenever consent or approval of either party is required, that party shall not
unreasonably withhold, condition or delay such consent or approval, except as may be expressly set forth to the contrary. 
 40.12. 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. 
 40.13. 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. 
 40.14. 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. 

  
 56 








 40.15. 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. Landlord 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. 

40.16. This Lease may be executed in one or more counterparts, each of which, when taken together, shall constitute one and the same document.
Signature pages may be detached from the counterparts and attached to a single copy of this Lease to form one (1) document. A facsimile, electronic or portable document format (PDF) signature on this Lease shall be equivalent to, and have the
same force and effect as, an original signature. 
 40.17. No provision of this Lease may be modified, amended or supplemented except by an
agreement in writing signed by Landlord and Tenant. 
 40.18. No waiver of any term, covenant or condition of this Lease shall be binding
upon Landlord unless executed in writing by Landlord. No waiver of any term, covenant or condition of this Lease shall be binding upon Tenant unless executed in writing by Tenant. The waiver by Landlord or Tenant 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. 

40.19. 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 out of 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. 
 41. [Intentionally omitted] 
 42. Options to
Extend Term. Tenant shall have two (2) options (each, an “Option”) to extend the Term by three (3) years each as to the entire Premises (and no less than the entire Premises) upon the following terms and conditions.
Any extension of the Term pursuant to an Option shall be on all the same terms and conditions as this Lease, except as follows: 
 42.1. Base
Rent during each Option term (including annual escalations, if any) shall equal the then-current fair market value for comparable office space in the Rockville, Maryland submarket of comparable age, quality, level of finish and proximity to
amenities and public transit (“FMV”). Tenant may, no more than twelve (12) months prior to the date the Term is then scheduled to expire, request Landlord’s estimate of the FMV for the next 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 an 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 

  
 57 








 
relevant factors, including (a) the size of the Premises, (b) the length of the Option term, (c) rent in comparable buildings in the relevant submarket, including concessions
offered to new tenants, such as free rent, tenant improvement allowances and moving allowances, (d) Tenant’s creditworthiness and (e) 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 an 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 Rockville, Maryland office leasing submarket (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 office space in the Rockville, Maryland submarket 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 applicable Option term. If, as of the
commencement date of an 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 applicable Option term and
any overpayment or underpayment of Base Rent for the Option term prior to such determination shall be adjusted between the parties. Any failure of the parties to execute such amendment shall not affect the validity of the FMV determined pursuant to
this Section. 
 42.2. No Option is assignable separate and apart from this Lease. 

42.3. An Option is conditional upon Tenant giving Landlord written notice of its election to exercise such Option at least nine
(9) 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 an Option. Tenant assumes full responsibility for maintaining a record of the deadlines to exercise an Option.
Tenant acknowledges that it would be inequitable to require Landlord to accept any exercise of an Option after the date provided for in this Section. 

42.4. Notwithstanding anything contained in this Article to the contrary, Tenant shall not have the right to exercise an Option: 

  
 58 








 (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; 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 a separate 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 three (3) or more times during the twelve (12)-month period immediately prior to the date that Tenant intends to exercise an Option, whether or not Tenant has cured such defaults.

 42.5. The period of time within which Tenant may exercise an 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 an Option shall terminate and be of no further force or effect even after Tenant’s due and timely exercise of such 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, (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 three (3) 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. 
 43. Right of First Refusal. Commencing upon the Term Commencement Date, but subject to any other parties’
pre-existing rights existing on the Term Commencement Date with respect to Available ROFR Premises (as defined below) (including, without limitation, any such rights granted to GlycoMimetics, Inc.), Tenant shall have a right of first refusal
(“ROFR”) as to any rentable premises on the second (2nd) floor of the building located at 9714 Medical Center Drive, Rockville, Maryland, for which Landlord is seeking a
tenant (“Available ROFR Premises”); provided, however, that in no event shall Landlord be required to lease any Available ROFR Premises to Tenant for any period past the date on which this Lease expires or is terminated
pursuant to its terms. To the extent that Landlord renews or extends a then-existing lease with any then-existing tenant or subtenant of any space, or enters into a new lease with such then-existing tenant or subtenant for the same premises, the
affected space shall not be deemed to be Available ROFR Premises. In the event Landlord receives from a third party a bona fide offer to lease Available ROFR Premises, Landlord shall provide written notice thereof to Tenant (the “Notice of
Offer”), specifying the terms and conditions of a proposed lease to Tenant of the Available ROFR Premises. 
 43.1. Within ten
(10) days following its receipt of a Notice of Offer, Tenant shall advise Landlord in writing whether Tenant elects to lease all (not just a portion) of the Available ROFR Premises on the terms and conditions set forth in the Notice of Offer.
If Tenant fails to notify 

  
 59 








 
Landlord of Tenant’s election within such ten (10) day period, then Tenant shall be deemed to have elected not to lease the Available ROFR Premises. 

43.2. If Tenant timely notifies Landlord that Tenant elects to lease the Available ROFR Premises on the terms and conditions set forth in the
Notice of Offer, then Landlord shall lease the Available ROFR Premises to Tenant upon the terms and conditions set forth in the Notice of Offer. 

43.3. If Tenant notifies Landlord that Tenant elects not to lease the Available ROFR Premises on the terms and conditions set forth in the
Notice of Offer, or if Tenant fails to notify Landlord of Tenant’s election within the ten (10)-day period described above, then Landlord shall have the right to consummate the lease of the Available ROFR Premises on the same terms as set forth
in the Notice of Offer following Tenant’s election (or deemed election) not to lease the Available ROFR Premises. If Landlord does not lease the Available ROFR Premises within one hundred eighty (180) days after Tenant’s election (or
deemed election) not to lease the Available ROFR Premises, then the ROFR shall be fully reinstated, and Landlord shall not thereafter lease the Available ROFR Premises without first complying with the procedures set forth in this Article. 

43.4. Notwithstanding anything in this Article to the contrary, Tenant shall not exercise the ROFR during such period of time that Tenant is
in Default under any provision of this Lease. Any attempted exercise of the ROFR during a period of time in which Tenant is so in Default shall be void and of no effect. In addition, Tenant shall not be entitled to exercise the ROFR if Landlord has
given Tenant two (2) or more notices of default under this Lease, whether or not the defaults are cured, during the twelve (12) month period prior to the date on which Tenant seeks to exercise the ROFR. 

43.5. Notwithstanding anything in this Lease to the contrary, Tenant shall not assign or transfer the ROFR, either separately or in
conjunction with an assignment or transfer of Tenant’s interest in the Lease, without Landlord’s prior written consent, which consent Landlord may withhold in its sole and absolute discretion. 

43.6. If Tenant exercises the ROFR, Landlord does not guarantee that the Available ROFR Premises will be available on the anticipated
commencement date for the Lease as to such Available ROFR Premises due to a holdover by the then-existing occupants of the Available ROFR Premises or for any other reason beyond Landlord’s reasonable control. 

43.7. At any time following the Term Commencement Date, upon Tenant’s request, Landlord shall advise Tenant of any other parties holding
pre-existing rights with respect to Available ROFR Premises. 
 44. Existing Furniture. Concurrently with the execution of this Lease, Landlord and
Tenant shall execute and deliver a Bill of Sale substantially in the form of attached Exhibit D, whereby Landlord shall convey to Tenant any rights Landlord has in certain personal property.

		(the “Beneficiary”)

	Loan No. :                                   
              				

 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 p.m. on
             or, if such day is not a Banking Day, then the next succeeding Banking Day (such date, as extended from time to time, the “Expiry Date”).
“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. 

Funds under this L/C are available by presenting the following documentation (the “Drawing Documentation”): (a) the
original L/C and (b) a sight draft substantially in the form of Attachment 1, with blanks filled in and bracketed items provided as appropriate. No other evidence of authority, certificate, or documentation is required. 

Drawing Documentation must be presented at Issuer’s office at
                     on or before the Expiry Date by personal presentation, courier or messenger service, or fax. Presentation by fax shall be
effective upon electronic confirmation of transmission as evidenced by a printed report from the sender’s fax machine. After any fax presentation, but not as a condition to its effectiveness, Beneficiary shall with reasonable promptness deliver
the original Drawing Documentation by any 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 Documentation this L/C requires. 

  
 E-1 








 We shall pay this L/C only from our own funds by check or wire transfer, in compliance with the
Drawing Documentation. 
 If Beneficiary presents proper Drawing Documentation to us on or before the Expiry Date, then we shall pay under
this L/C at or before the following time (the “Payment Deadline”): (a) if presentment is made at or before noon of any Banking Day, then the close of such Banking Day; and (b) otherwise, the close of the next Banking Day.
We waive any right to delay payment beyond the Payment Deadline. If we determine that Drawing Documentation is not proper, then we shall so advise Beneficiary in writing, specifying all grounds for our determination, within one Banking Day after the
Payment Deadline. 
 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. 
 The Expiry Date shall automatically be extended by one year (but never beyond
             (the “Outside Date”)) unless, on or before the date 90 days before any Expiry Date, we have given Beneficiary notice that the Expiry Date shall not be
so extended (a “Nonrenewal Notice”). We shall promptly upon request confirm any extension of the Expiry Date under the preceding sentence by issuing an amendment to this L/C, but such an amendment is not required 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. Beneficiary or
Transferee shall consummate such transfer by delivering to Issuer the original of this L/C and a Transfer Notice substantially in the form of Attachment 2, purportedly signed by Beneficiary, and designating Transferee. Issuer 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. 
 Any notice to Beneficiary shall be in writing and delivered by hand with
receipt acknowledged or by overnight delivery service such as FedEx (with proof of delivery) at the above address, or such other address as Beneficiary may specify by written notice to Issuer. A copy of any such notice shall also be delivered, as a
condition to the effectiveness of such notice, to:                      (or such replacement as Beneficiary designates from time to time by
written notice). 
 No amendment that adversely affects Beneficiary shall be effective without Beneficiary’s written consent. 

  
 E-2 








 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.
