year, at the option of Landlord such expense may be proportionately allocated among such related calendar years; provided that only those periods falling within the Term of the Lease shall be

the Building and the remainder of the Project or Campus. In addition, Operating Expenses shall be reduced by all cash discounts, trade discounts or quantity discounts received by Landlord or Landlord’s managing agent in the purchase of any
goods, utilities or services in connection with the prudent operation of the Building. Operating Expenses for the Property that are not, in Landlord’s reasonable discretion, allocable solely to either the office or laboratory portion of the
Building shall be equitably allocated by Landlord between/amongst such uses. The above enumeration of services and facilities shall not be deemed to impose an obligation on Landlord to make available or provide such services or facilities except to
the extent if any that Landlord has specifically agreed elsewhere in this Lease to make the same available or provide the same. 
 PREMISES:
The space located in the Building at the Suite Numbers listed in Section 1.1 and depicted on Exhibit A attached hereto.

management; indoor air quality; and chemical use.

any personal property used in connection therewith) or Landlord’s business of owning and operating the Property, which may also include any rental, revenue, general gross receipts or similar taxes levied in lieu of or in addition to general
real and/or personal property taxes, but only to the extent such taxes, assessments, license fees and charges accrued during and relate to the Tenn. For purposes hereof, Taxes for any year shall be Taxes which are assessed for any period of such
year falling within the Term, whether or not such Taxes are billed and payable in a subsequent calendar year. There shall be included in Taxes for any year falling within the Tern the amount of all fees, costs and expenses (including reasonable

purposes as fire protection, street, sidewalk, road, utility construction and maintenance, refuse removal and for other governmental services which may formerly have been provided without charge to property owners or occupants. Other than Excluded
Taxes, it is the intention of the parties that all new and increased assessments, taxes, fees, levies and charges due to any cause whatsoever are to be included within the definition of Taxes for purposes of this Lease.

PREMISES, TERM, FAILURE TO GIVE POSSESSION, AND PARKING 

2.1 LEASE OF PREMISES; EXISTING LEASE; RIGHT OF FIRST OFFER 

(a) Existing Lease. Tenant currently leases the Premises (other than Suite 120) pursuant to the terms of that certain Laboratory Lease
dated August 20, 2014 (the “Original Lease”), as amended by that certain First Amendment to Laboratory Lease dated October 29, 2015 (the “Existing Lease First Amendment”), that certain Second Amendment to Laboratory
Lease dated April 29, 2016, that certain Third Amendment to Laboratory Lease dated April 3, 2018, that certain Fourth Amendment to Laboratory Lease dated September 6, 2018, that certain Fifth Amendment to Laboratory Lease dated
February I, 2019, and that certain Sixth Amendment to Laboratory Lease dated July 8, 2019 (collectively, the “Existing Lease”), the term of which lease expires as of December 31, 2025. It is the intent of the parties that this
Lease shall amend, restate, supersede and replace in its entirety the Existing Lease. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the Premises for the Term and upon the terms, covenants and conditions provided in this
Lease. 
 (b) Right of First Offer. 

(1) Tenant shall have a one-time right of first offer (the “Right of First Offer”) with respect to Suite 130 on the first floor of
the Building, consisting of approximately 10,062 square feet of Rentable Area, and Suite 200 on the second floors of the Building, consisting of approximately 7,140 square feet of Rentable Area (both as shown on Exhibit A-I to this Lease),
following the date of this Lease (the “Offering Spaces”). If Tenant leases either of the Offering Spaces pursuant to the terms of this Section 2.1(b), then Tenant shall have a one-time right of first offer on the other Offering Space
pursuant to the terms of this Section 2.1(b). 

  
 - 13 - 













 (2) Landlord and Tenant acknowledge that the Offering Spaces are currently leased to
existing tenants. Prior to the date Landlord offers either of the Offering Spaces for lease to a potential third-patty tenant or other potential occupant (other than to any of such existing tenants), Landlord shall advise Tenant (the
“Advice”) of the terms under which Landlord is prepared to lease such Offering Space to Tenant. Tenant may lease such Offering Space in its entirety only, under such terms, by delivering written notice of exercise to Landlord (the
“Notice of Exercise”) within five (5) days after the date of the Advice, except that Tenant shall have no such Right of First Offer, and Tenant may not exercise its right under this Section 2.1(b), if: (i) at the time that
Landlord would otherwise deliver the Advice, a Default on the part of Tenant exists under this Lease or there then exists any event or condition which, with the giving of notice or the passage of time or both, would constitute such a Default;
(ii) any portion of the Premises is sublet at the time Landlord would otherwise deliver the Advice; (iii) Tenant is not occupying the entire Premises (other than due to a casualty or condemnation event); (iv) the Offering Space is not
intended for the exclusive use of Tenant; or (v) Tenant cannot demonstrate to Landlord’s reasonable satisfaction that Tenant’s creditworthiness is sufficient in light of the increased Rent obligations associated with the Offering
Space. Tenant shall deliver evidence of Tenant’s creditworthiness concurrently with delivery of the Notice of Exercise. 
 (3) The term
with respect to the Offering Space (the “Offering Space Term”) shall be as stated in the Advice and upon commencement of the Offering Space Term, the Offering Space shall be considered a part of the Premises, provided that all of the terms
stated in the Advice shall govern Tenant’s leasing of the Offering Space and only to the extent that they do not conflict with the Advice, the terms and conditions of this Lease shall apply to the Offering Space. The foregoing notwithstanding,
if Landlord is unable to deliver possession of the Offering Space to Tenant on the commencement of the Offering Space Term as stated in the Advice, Landlord shall not be liable for any claims, damages or liabilities by reason thereof, but the
Offering Space Term shall commence upon the date possession of the Offering Space is delivered by Landlord to Tenant. The Offering Space shall be accepted by Tenant in “AS IS” condition, and Landlord’s only obligation with respect to
the condition of the Offering Space as of the commencement of the Offering Space Term shall be to deliver such Offering Space in such condition. 

(4) Tenant shall pay Monthly Base Rent for the Offering Space at the rate or rates set forth in the Advice, which rate or rates shall reflect
the Fair Market Rent for the Offering Space as determined by Landlord in Landlord’s reasonable judgment. For purposes of this Right of First Offer provision (and notwithstanding how “Fair Market Rent” is determined under
Section 2.2(b) below), “Fair Market Rent” shall mean the annual rental rate per square foot for space comparable to the Offering Space in the Building and laboratory buildings comparable to the Building in Berkeley and Emeryville,
California under leases and renewal and expansion amendments being entered into at or about the time that the Fair Market Rent is being determined, giving appropriate consideration to tenant concessions, brokerage commissions, tenant improvement
allowances, and the method of allocating operating expenses and taxes. Notwithstanding the foregoing, space leased under any of the following circumstances shall not be considered to be comparable for purposes hereof: (i) the lease term is for
less than the lease term of the Offering Space, (ii) the space is encumbered by the option rights of another tenant, or (iii) the space has a lack of windows and/or an awkward or unusual shape or configuration. The foregoing is not
intended to be an exclusive list of space that will not be considered to be comparable. The determination of Fair Market Rent shall also take into consideration any reasonably anticipated changes in the Fair Market Rent from the time such Fair
Market Rent is being determined and the time such Fair Market Rent will become effective under the Lease. 
 (5) The Right of First Offer
shall terminate on the earliest to occur of: (i) Tenant’s failure to exercise its Right of First Offer within the 5-day period provided in Section 2.1(b)(2) above as to either Offering Space; (ii) the date Landlord would have
provided Tenant with an Advice if Tenant had not been in violation of one or more of the conditions set forth in Section 2.1(b)(2); or (iii) the expiration or earlier termination of the Term (as the same may be extended pursuant to
Section 2.2(b) below). 
 (6) If Tenant exercises its Right of First Offer as to any of the Offering Spaces, Landlord shall prepare an
amendment (the “Offering Amendment”) adding the subject Offering Space to the Premises on the terms set forth in the Advice and reflecting the changes in the Monthly Base Rent, Rentable Square Footage of the Premises and other appropriate
terms. A copy of the Offering Amendment shall be sent to Tenant within a reasonable time after Landlord’s receipt of the Notice of Exercise executed by Tenant, and Tenant shall execute and return the Offering Amendment to Landlord within
fifteen (15) days thereafter, but an otherwise valid exercise of the Right of First Offer shall be fully effective whether or not the Offering Amendment is prepared and/or executed. 

(7) Notwithstanding anything to the contrary contained herein, Tenant’s Right of First Offer is subject and subordinate to the expansion
rights (whether such rights are designated as a right of first offer, right of first refusal, expansion option or otherwise) of any tenant or other occupant of the Building existing as of the date of this Lease. 

  
 - 14 - 













 (8) Notwithstanding anything to the contrary contained herein, Tenant’s rights under
this Section 2.1(b) are personal to the original Tenant executing this Lease or a Permitted Transferee to whom this Lease is assigned (“Named Tenant”) and shall not be assigned or assignable, in whole or in part, to any third-party
other than a Permitted Transferee. Any assignment or other transfer of such rights by Named Tenant shall be void and of no force or effect. Without limiting the generality of the foregoing, no sublessee of the Premises shall be permitted to exercise
the rights granted to Tenant under this Section 2.l(b). 
 2.2 TERM 

(a) Initial Tenn. The initial term of this Lease (“Initial Tern”) shall be as set forth in Section 1.1(5). 

(b) Option to Extend. Provided that (i) Tenant has not sublet any portion of the Premises other than Suite 120, and (ii) no
monetary Default or material non-monetary Default by Tenant exists at the time of exercise or at the time of commencement of the Extended Term, the Term of this Lease shall be subject to one (I) extension option for an additional period of
sixty (60) months (the “Extension Option”), commencing as of the expiration of the Initial Tern, and expiring on the date that is sixty (60) full calendar months thereafter (the “Extended Term”), exercisable as follows:

 (1) The Extension Option shall be upon the same material terms and conditions contained in this Lease, except that (i) the initial
Monthly Base Rent for the Premises shall be equal to the fair market rent for the Premises determined in the manner set forth in Section 2.2(b)(3) below, (ii) on each anniversary of the commencement date of the Extended Term, the Monthly
Base Rent shall increase three and one-half percent (3\/,%), on a cumulative basis, and (iii) Tenant shall accept the Premises in an “as is” condition without any obligation of Landlord to repaint, remodel, repair, improve or alter
the Premises (subject, however, to the terms of Section 8.1 of the Lease). 
 (2) Tenant’s election to exercise the Extension
Option must be given to Landlord in writing no less than three hundred and sixty-five (365) days prior to the expiration of the Initial Term (the “Extension Notice”). Within thirty (30) days of Landlord’s receipt of the
Extension Notice, Landlord shall send Tenant written notice of Landlord’s good faith determination of the Fair Market Rent for the Premises (the “Fair Market Rent Notice”). For purposes of this Section, the term “Fair Market
Rent” shall mean the base rental rate, periodic rental rate adjustment and other charges and increases, if any, for space comparable in size, location and quality to the Premises under a primary lease (and not sublease) to new or renewing
tenants, for a comparable term with a tenant improvement allowance, if applicable and taking into consideration such amenities as existing improvements, view, floor on which the Premises are situated and the like, situated in buildings in Berkeley
and Emeryville, California. Notwithstanding anything to the contrary contained herein, the Extension Option shall automatically terminate and be of no further force or effect, whether or not Tenant has timely exercised the Extension Option, if a
monetary Default or material non-monetary Default exists at the time of exercise of the Extension Option or at the time of commencement of the Extended Term. 

(3) If Tenant properly exercises the Extension Option, the Monthly Base Rent during the Extended Term shall be determined in the following
manner. The Monthly Base Rent as of the commencement of the Extended Term shall be adjusted to an amount equal to the Fair Market Rent for the Premises as specified in the Fair Market Rent Notice, subject to Tenant’s right of arbitration as set
forth below. Notwithstanding the above, under no circumstances will the Monthly Base Rent during the first twelve (12) months of the Extension Term be less than the Monthly Base Rent for the last month of the Initial Term. If Tenant believes
that the Fair Market Rent specified in the Fair Market Rent Notice exceeds the actual Fair Market Rent for the Premises as of the date of such notice, then Tenant shall so notify Landlord within ten (10) days of Tenant’s receipt of the
Fair Market Rent Notice. If Tenant fails to so notify Landlord within such 10-day period, Landlord’s determination of the Fair Market Rent shall be final and binding upon the parties. If the parties are unable to agree upon the Fair Market Rent
within ten (10) days after Landlord’s receipt of Tenant’s objection to the Fair Market Rent Notice, the amount of Monthly Base Rent as of the commencement of the Extended Term shall be determined as follows: 

  
 - 15 - 













 (i) Within twenty (20) days after the 10-day period has expired and the parties have
failed to agree on the Fair Market Rent, Tenant, at its sole expense, shall obtain and deliver in writing to Landlord a determination of the Fair Market Rent for the Premises for a term equal to the Extended Term from a broker (“Tenant’s
Broker”) licensed in the State of California and engaged in the laboratory brokerage business in Berkeley/Emeryville, California, for at least the immediately preceding five (5) years. If Landlord accepts such determination, the Monthly
Base Rent for the Extended Term shall be adjusted to an amount equal to the amount determined by Tenant’s Broker. 
 (ii) If Landlord
does not accept such determination, within fifteen (15) days after receipt of the determination of Tenant’s broker, Landlord shall designate a broker (“Landlord’s Broker”) licensed in the State of California and engaged in
the laboratory brokerage business in Berkeley/Emeryville, California, for at least the immediately preceding five (5) years. Landlord’s Broker and Tenant’s Broker shall name a third broker, similarly qualified, within five
(5) days after appointment of Landlord’s Broker. Landlord’s Broker and Tenant’s Broker shall each determine the Fair Market Rent for the Premises as of the commencement of the Extended Term for a term equal to the Extended Term
within fifteen (15) days after the appointment of the third broker. The Monthly Base Rent payable by Tenant effective as of the commencement of the Extended Term shall be adjusted to an amount equal to the determination of Fair Market Rent made
by either Landlord’s Broker or Tenant’s Broker that the third broker finds to be closer to the Fair Market Rent. 
 (iii) Landlord
shall pay the costs and fees of Landlord’s Broker in connection with any determination hereunder, and Tenant shall pay the costs and fees of Tenant’s Broker in connection with such determination. The costs and fees of any third broker
shall be paid one-half by Landlord and one-half by Tenant. 
 (4) If the amount of the Fair Market Rent is not known as of the commencement
of the Extended Term, then Tenant shall continue to pay the Monthly Base Rent for the Premises in effect at the expiration of the Extended Term until the amount of the Fair Market Rent is determined. When such determination is made, Tenant shall pay
any deficiency to Landlord upon demand. 
 (5) In connection with the extension of the Term pursuant to Tenant’s exercise of the
Extension Option, the parties acknowledge and agree that Landlord shall not be responsible for the payment to any real estate broker, salesperson or finder claiming to have represented Tenant of any commission, finder’s fee or other
compensation in connection with or as a consequence of Tenant’s exercise of the Extension Option. 
 (6) Notwithstanding anything to the
contrary contained herein, except with respect to a Permitted Transferee, Tenant’s rights under this Section 2.2(b) are personal to Named Tenant and shall not be assigned or assignable, in whole or in part, to any third party other than a
Permitted Transferee. Any assignment or other transfer of such rights by Named Tenant in violation of the preceding sentence shall be void and of no force or effect. Without limiting the generality of the foregoing, no sublessee of the Premises
shall be permitted to exercise the rights granted to Tenant under this Section 2.2(b). 
 2.3 FAILURE TO DELIVER POSSESSION 

If Suite 120 is not delivered to Tenant with the Landlord Work Substantially Completed by the Commencement Date for any reason, Landlord shall
not be liable for any claims, damages or liabilities by reason thereof, nor affect the validity of this Lease or the obligations of Tenant hereunder; provided, however, the Commencement Date as to Suite 120 only shall be adjusted to reflect the
actual delivery date, and Landlord and Tenant shall enter into a commercially reasonable form of memorandum to memorialize the Commencement Date as to Suite 120 only, and the Commencement Date as to the balance of the Premises shall remain as set
forth in the Basic Lease Information. Notwithstanding the foregoing to the contrary, if Landlord is unable to so deliver Suite 120 by the date (the “Outside Suite 120 Delivery Date”) that is ninety (90) days after the Commencement
Date (which Outside Suite 120 Delivery Date shall be subject to extension day- for-day for Force Majeure events), then Tenant may, at its option, by notice in writing (the “Suite 120 Termination
Notice”) within thirty (30) days after the Outside Suite 120 Delivery Date cancel this Lease as to Suite 120 only, in which event Landlord and Tenant shall be discharged from all obligations hereunder relating to Suite 120, and Landlord
shall return to Tenant any prepaid rent relating to Suite 120 and the Additional Security Deposit, and both parties shall be released from all obligations under this Lease relating to Suite 120 (excepting only those obligations, such as
indemnification and defense obligations, which are expressly intended to survive the termination of this Lease). If the Termination Notice is not received by Landlord within said thirty (30) day period, Tenant’s right to cancel as to Suite
120 shall terminate. The remedy set forth above shall be Tenant’s sole remedy in the event of a delay in delivering possession of Suite 120 to Tenant. In no event shall Landlord be liable for special or consequential damages as a result of any
such delay, and no such termination shall modify Tenant’s obligations under this Lease as to the balance of the Premises. 

  
 - 16 - 













 2.4 CONDITION OF PREMISES 

Landlord shall deliver possession of Suite 120 to Tenant with the Landlord Work Substantially Completed, in vacant, broom clean condition, with
all Building systems in good working order, and free of all tenancies and other occupancy rights other than Tenant’s pursuant to this Lease. Tenant shall notify Landlord in writing within thirty (30) days after the Commencement Date of any
defects in Suite 120 claimed by Tenant or in the materials or workmanship furnished by Landlord in completing the Landlord Work, if any (the “Suite 120 Patent Defect Notice”). Tenant is not waiving its right to have Landlord repair any
latent defects that may exist (if any) in Suite 120, and Landlord shall have the obligation (as Tenant’s sole remedy) to repair such latent defects, if any, which are discovered by Tenant and reported to Landlord in writing within ninety
(90) days after the Commencement Date (the “Suite 120 Latent Defect Notice” and collectively with the Suite 120 Patent Defect Notice, the “Suite 120 Defect Notices”). As specified in Section 2.l above, Tenant currently
leases the Premises (other than Suite 120) pursuant to the terms of the Existing Lease. Therefore, except for defects stated in the Suite 120 Defect Notices, and subject to any representations, warranties or covenants of Landlord expressly set forth
in this Lease, Tenant shall be conclusively deemed to have (a) accepted the Premises “AS IS” in the condition existing on (i) the date of this Lease, as to all of the Premises other than Suite 120, and (ii) as of the date
Tenant first takes possession of Suite 120, as to Suite 120, and (b) waived all claims relating to the condition of the Premises. Landlord shall proceed diligently to correct the defects stated in the Suite 120 Defect Notices unless Landlord
disputes the existence of any such defects. In the event of any dispute as to the existence of any such defects, the good faith decision of Landlord’s architect shall be final and binding on the parties. No agreement of Landlord to alter,
remodel, decorate, clean or improve the Premises or the Real Property and no representation regarding the condition of the Premises or the Real Property has been made by or on behalf of Landlord to Tenant, except as may be specifically stated in
this Lease or in the Workletter. Nothing in this Section 2.4 shall be deemed to relieve Landlord from any of its duties or obligations expressly set forth in this Lease or the Workletter. 

2.5 PARKING 
 During the Term, Tenant may
use the number of spaces specified in Section 1.1(12) for parking at the rates specified in Section 1.1(12). In the event Tenant fails at any time to pay the full amount of such parking charges, until the delinquent amount is paid
Tenant’s parking rights may be reduced to the extent of Tenant’s failure to pay for any such parking. The locations and type of parking (including, without limitation, valet parking, if any) shall be designated by Landlord or
Landlord’s parking operator from time to time. All of the spaces shall be unreserved spaces (other than the Building Spaces) and shall be located within the Aquatic Park Center in either parking lots or structured parking garages (other than
the Building Spaces). Tenant acknowledges and agrees that the parking spaces serving the Project may include tandem or valet parking and a mixture of spaces for compact vehicles as well as full-size passenger automobiles, and that Tenant shall not
use parking spaces for vehicles larger than the striped size of the parking spaces. All vehicles utilizing Tenant’s parking spaces shall prominently display identification stickers or other markers, and/or have passes or keycards for ingress
and egress, as may be required and provided by Landlord or its parking operator from time to time. Tenant shall comply with any and all parking rules and regulations from time to time established by Landlord or Landlord’s parking operator,
including a requirement that Tenant pay to Landlord or Landlord’s parking operator a charge for loss and replacement of passes, keycards, identification stickers or markers, and for any and all loss or other damage caused by persons or vehicles
related to use of Tenant’s parking spaces. Tenant shall not allow any vehicles using Tenant’s parking spaces to be parked, loaded or unloaded except in accordance with this Section, including in the areas and in the manner designated by
Landlord or its parking operator for such activities. If any vehicle is using the parking or loading areas contrary to any provision of this Section, Landlord or its parking operator shall have the right, in addition to all other rights and remedies
of Landlord under this Lease, to remove or tow away the vehicle without prior notice to Tenant, and the cost thereof shall be paid to Landlord within ten (I 0) days after notice from Landlord. 

To the extent Landlord continues to have such technology available in the Common Areas, Landlord shall keep all EV charging stations located
in the parking areas that serve the Premises as of the Commencement Date in good condition, repair and working order throughout the Tenn. The cost of all such maintenance and repair shall be included in Operating Expenses. 

  
 - 17 - 













 ARTICLE 3 

RENT 
 From and after the
Commencement Date, Tenant shall pay to Landlord at the address specified in Section 1.1(2), or to such other persons, or at such other places designated by Landlord, without any prior demand therefor in immediately available funds and without
any deduction or offset whatsoever (except as expressly provided herein), Rent, including Monthly Base Rent and Rent Adjustments in accordance with Article 4, during the Term. Monthly Base Rent shall be paid monthly in advance on or prior to the
first day of each month of the Term, except that the first installment of Monthly Base Rent shall be paid by Tenant to Landlord concurrently with Tenant’s execution of this Lease. Monthly Base Rent shall be prorated for partial months within
the Term. Tenant’s covenant to pay Rent shall be independent of every other covenant in this Lease. 
 ARTICLE 4 

RENT ADJUSTMENTS AND PAYMENTS 
 4.1 RENT
ADJUSTMENTS 
 (a) From and after the Commencement Date until the Termination Date, Tenant shall pay to Landlord Rent Adjustments with
respect to each calendar year (or partial calendar year in the case of the year in which the Commencement Date and the Termination Date occur) as follows: 

(1) The Rent Adjustment Deposit representing Tenant’s Share of Operating Expenses for the applicable calendar year (or partial calendar
year), monthly during the Term with the payment of Monthly Base Rent; 
 (2) The Rent Adjustment Deposit representing Tenant’s Share of
Taxes for the applicable calendar year (or partial calendar year), monthly during the Term with the payment of Monthly Base Rent; and 
 (3)
Any Rent Adjustments due in excess of the Rent Adjustment Deposits in accordance with Section 4.2. Rent Adjustments due from Tenant to Landlord for any calendar year (or partial calendar year) shall be Tenant’s Share of Operating Expenses
for such calendar year (or partial calendar year) and Tenant’s Share of Taxes for such calendar year (or partial calendar year). 
 (b)
On or before the beginning of each calendar year or with Landlord’s Statement (as defined in Section 4.2 below), Landlord may estimate and notify Tenant in writing of its estimate of the amount of Operating Expenses and Taxes payable by
Tenant for such calendar year. Prior to the first determination by Landlord of the amount of Operating Expenses and Taxes for the first calendar year, Landlord may estimate such amounts in the foregoing calculation. Landlord shall have the right
from time to time but not more than once during any calendar year to provide a new or revised estimate of Operating Expenses and/or Taxes and to notify Tenant in writing thereof, of corresponding adjustments in Tenant’s Rent Adjustment Deposit
payable over the remainder of such year, and of the amount or revised amount due allocable to months preceding such change. The last estimate by Landlord shall remain in effect as the applicable Rent Adjustment Deposit unless and until Landlord
notifies Tenant in writing of a change, which notice may be given by Landlord from time to time but not more than once during any calendar year throughout the Term. 

(c) For purposes of determining Rent Adjustments, if the Building or Property is not fully occupied during all or a portion of any calendar
year during the Term, Landlord shall make appropriate adjustments to the variable components of Operating Expenses for such calendar year (or partial calendar year), employing sound accounting and management principles consistently applied, to
determine the amount of Operating Expenses that would have been paid or incurred by Landlord had the Building been one hundred percent (I 00%) occupied, and the amount so determined shall be deemed to have been the amount of Operating Expenses for
such calendar year (or partial calendar year). In the event that the Property is not fully assessed for all or a portion of any calendar year (or partial calendar year) during the Term, then Taxes shall be adjusted to an amount which would have been
payable in such calendar year (or partial calendar year) if the Property had been fully assessed. In addition, Landlord shall have the right, at its sole discretion, from time to time, to equitably allocate certain Operating Expenses among only
certain tenants of the Project as to any expense or cost that relates to a repair, replacement or service that benefits only those tenants, and the Rent Adjustments shall reflect any such allocations.

 4.2 STATEMENT OF LANDLORD 

As soon as practical after the expiration of each calendar year, Landlord will furnish Tenant with a statement respecting the prior calendar
year (“Landlord’s Statement”) showing the following: 
 (a) The amount of actual Operating Expenses and Taxes for such
calendar year; 
 (b) The amount of Rent Adjustments due Landlord for the last calendar year, less credit for Rent Adjustment Deposits paid,
if any; and 
 (c) Any change in the Rent Adjustment Deposit due monthly in the current calendar year, including the amount or revised amount
due for months preceding any such change pursuant to Landlord’s Statement. 
 Tenant shall pay to Landlord within ten (10) days
after receipt of such statement any amounts for Rent Adjustments then due in accordance with Landlord’s Statement. Any amounts due from Landlord to Tenant pursuant to this Section shall be credited to the Rent Adjustment Deposit next corning
due, or promptly refunded to Tenant if the Term has already expired or terminated, provided Tenant is not in Default hereunder. No interest or penalties shall accrue on any amounts that Landlord is obligated to credit or refund to Tenant by reason
of this Section 4.2. Landlord’s failure to deliver Landlord’s Statement or to compute the amount of the Rent Adjustments shall not constitute a waiver by Landlord of its right to deliver such items nor constitute a waiver or release
of Tenant’s obligations to pay such amounts, unless Landlord fails to deliver such Landlord’s Statement as to Operating Expenses or Taxes (unless such delivery delay as to Taxes is due to a delay in the taxing authority providing updated
Tax information) within twenty-four (24) months following the conclusion of the applicable calendar year. The Rent Adjustment Deposit shall be credited against Rent Adjustments due for the applicable calendar year (or partial calendar year).
During the last complete calendar year or during any partial calendar year in which this Lease expires or terminates, Landlord may include in the Rent Adjustment Deposit its estimate of Rent Adjustments which might not be finally determined until
after the expiration or termination of this Lease. Tenant’s obligation to pay Rent Adjustments survives the expiration or termination of this Lease. 

4.3 BOOKS AND RECORDS 
 Landlord shall
maintain books and records showing Operating Expenses and Taxes in accordance with sound accounting and management practices, consistently applied. Tenant or its representative (which representative shall be a certified public accountant licensed to
do business in the state in which the Property is located and whose primary business is certified public accounting and who shall not be paid on a contingency basis) shall have the right, for a period of sixty (60) days following the date upon
which Landlord’s Statement is delivered to Tenant, to examine Landlord’s books and records with respect to the items in the foregoing statement of Operating Expenses and Taxes during normal business hours, upon written notice, delivered at
least three (3) Business Days in advance. Tenant shall pay for all costs of such examination, provided, however, if the examination reveals an overcharge of five percent (5%) or more, then Landlord shall pay for all reasonable and actual
third-party costs of such examination, up to a maximum amount of the lesser of the amount of the overcharge or Five Thousand Dollars ($5,000.00). If Tenant performs such examination, but does not object in writing to Landlord’s Statement within
ninety (90) days after Tenant’s receipt thereof, specifying the nature of the item in dispute and the reasons therefor, then Landlord’s Statement shall be considered final and accepted by Tenant and Tenant shall be deemed to have
waived its right to dispute Landlord’s Statement. If Tenant does dispute any Landlord’s Statement, Tenant shall deliver a copy of any such audit to Landlord at the time of notification of the dispute. If Tenant does not provide such notice
of dispute and a copy of such audit to Landlord within such ninety (90) day period, it shall be deemed to have waived such right to dispute Landlord’s Statement. Any amount due to Landlord as shown on Landlord’s Statement, whether or
not disputed by Tenant as provided herein shall be paid by Tenant when due as provided above, without prejudice to any such written exception. In no event shall Tenant be permitted to examine Landlord’s records or to dispute any


  
 - 19 - 













 
statement of Operating Expenses and Taxes unless Tenant has paid and continues to pay all Rent when due. Upon resolution of any dispute with respect to Operating Expenses and Taxes, Tenant shall
either pay Landlord any shortfall or Landlord shall credit Tenant with respect to any overages paid by Tenant within thirty (30) days after such determination. The records obtained by Tenant shall be treated as confidential and neither Tenant
nor any of its representatives or agents shall disclose or discuss the information set forth in the audit to or with any other person or entity except (a) to or with Tenant’s directors, officers, attorneys, accountants, auditors, financial
advisors, investors, employees and consultants; or (b) as required by Law or legal process (the “Confidentiality Requirement”). Tenant shall indemnify and hold Landlord harmless for any losses or damages arising out of the breach of
the Confidentiality Requirement. 
 4.4 TENANT OR LEASE SPECIFIC TAXES 

In addition to Monthly Base Rent, Rent Adjustments, Rent Adjustment Deposits and other charges to be paid by Tenant, Tenant shall pay to
Landlord, upon demand, any and all taxes payable by Landlord (other than Excluded Taxes), whether or not now customary or within the contemplation of the parties hereto: (a) upon, allocable to, or measured by the Rent payable hereunder,
including any gross receipts tax or excise tax levied by any governmental or taxing body with respect to the receipt of such Rent; or (b) upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair,
use or occupancy by Tenant of the Premises or any portion thereof; or (c) upon the measured value of Tenant’s personal property located in the Premises or in any storeroom or any other place in the Premises or the Property, or the areas
used in connection with the operation of the Property, it being the intention of Landlord and Tenant that, to the extent possible, such personal property taxes shall be billed to and paid directly by Tenant; (d) resulting from any Tenant Work
or Tenant Alterations, whether title thereto is in Landlord or Tenant; or (e) upon this transaction. Taxes or supplemental taxes paid by Tenant pursuant to this Section 4.4 shall not be included in any computation of Taxes payable pursuant
to Sections 4.1 and 4.2, but the standard property management fees shall apply to any such payments. 
 ARTICLE 5 

SECURITY 
 (a)
Simultaneously with Tenant’s execution and delivery of this Lease to Landlord, Tenant shall pay Landlord in immediately available funds the cash amount of the Additional Security Deposit set forth in Section l. l(l 0) of this Lease, which
Additional Security Deposit, plus the amount held under the Existing Lease (as set forth in Section 1.1(10)), Landlord shall hold under this Lease for the full and faithful performance by Tenant of each and every term, provision, covenant, and
condition of this Lease. If Tenant fails to perform any of the terms, provisions, covenants and conditions of this Lease or any other document executed by Tenant in connection with this Lease beyond any applicable notice or cure period, then
Landlord may use, apply, or retain the whole or any part of the Security Deposit for the payment of any Rent not paid when due, for the cost of repairing any damage, for the cost of cleaning the Premises, for the payment of any other sum which
Landlord may expend or may be required to expend by reason of Tenant’s failure to perform, and otherwise for compensation of Landlord for any other loss or damage to Landlord occasioned by Tenant’s failure to perform, including, but not
limited to, any loss of future Rent and any damage or deficiency in the reletting of the Premises (whether such loss, damages or deficiency accrue before or after summary proceedings or other reentry by Landlord) and the amount of the unpaid past
Rent, future Rent loss, and all other losses, costs and damages, that Landlord would be entitled to recover if Landlord were to pursue recovery under Section 1 1.2(b) or (c) of this Lease or California Civil Code Section 1951.2 or
1951.4 (and any supplements, amendments, replacements and substitutions thereof and therefor from time to time). If Landlord so uses, applies or retains all or part of the Security Deposit, Tenant shall within five (5) Business Days after
demand pay or deliver to Landlord in immediately available funds the sum necessary to replace the amount used, applied or retained. The Security Deposit (except any amount retained for application by Landlord as provided herein) shall be returned to
Tenant within thirty (30) days after the later of: (i) the Termination Date or (ii) recovery of possession of the Premises by Landlord; provided, however, in no event shall any such return be construed as an admission by Landlord that
Tenant has performed all of its obligations hereunder. 

  
 - 20 - 













 (b) The Security Deposit shall not be deemed an advance rent deposit or an advance payment
of any kind, or a measure of Landlord’s damages with respect to Tenant’s failure to perform, nor shall any action or inaction of Landlord with respect to it or its use or application be a waiver of, or bar or defense to, enforcement of any
right or remedy of Landlord. Landlord shall not be required to keep the Security Deposit separate from its general funds and shall not have any fiduciary duties or other duties (except as set forth in this Section) concerning the Security Deposit.
Tenant shall not be entitled to any interest on the Security Deposit. In the event of any sale or other transfer of Landlord’s interest in the Building, Landlord shall have the right to transfer the Security Deposit, or balance thereof, to the
transferee and any such transfer shall release Landlord from all liability for the return of the Security Deposit if the Security Deposit is actually transferred to the purchaser of Landlord’s interest in the Building and such purchaser assumes
Landlord’s obligations under this Article 5. Tenant thereafter shall look solely to such transferee for the return or payment of the Security Deposit. Tenant shall not assign or encumber or attempt to assign or encumber the Security Deposit or
any interest in it and Landlord shall not be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance, and regardless of one or more assignments of this Lease, Landlord may return the Security Deposit to the original
Tenant without liability to any assignee. Tenant hereby waives any and all rights of Tenant under the provisions of Section 1950.7 of the California Civil Code, and any and all rights of Tenant under all provisions of Law, now or hereafter
enacted, regarding security deposits. 
 ARTICLE 6

 6.1 LANDLORD’S GENERAL
SERVICES 
 (a) Landlord shall furnish the following services the cost of which services shall be included in Operating Expenses or paid
directly by Tenant to the utility or service provider: 
 (1) heat, ventilation and air-conditioning (“HVAC”) in the Premises

interference with, Tenant’s business, including, but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, or other loss or damage, bodily injury or death, related to
any malfunction, circumvention or other failure of any security program, or for the failure of any security program to prevent bodily injury, death, or property damage, or loss, or to apprehend any person suspected of causing such injury, death,
damage or loss. 
 (c) If Tenant uses heat generating machines or equipment in the Premises to an extent which adversely affects the
temperature otherwise maintained by the air-cooling system or whenever the occupancy or electrical load adversely affects the temperature otherwise maintained by the air-cooling system, Landlord reserves the right to install or to require Tenant to
install supplementary air-conditioning units in the Premises. Tenant shall bear all costs and expenses related to the installation, maintenance and operation of such units. 

(d) Tenant shall pay Landlord at rates fixed by Landlord for all tenants in the Building, charges for all water furnished to the Premises

 - 21 - 













 (e) Commencing on the Commencement Date and throughout the remainder of the Term, Tenant
shall continue to have the exclusive right to connect to Landlord’s generator located in the East Lot (the “Generator”), which Generator is solely for the purpose of providing emergency electrical capacity to the Premises, subject to
the following terms and conditions: 
 (1) Tenant’s access to the Generator shall be limited to such times, rules and regulations as
Landlord may reasonably impose. Tenant shall be solely responsible for obtaining all necessary governmental and regulatory approvals, if any, required in order for Tenant to connect to the Generator. Tenant shall install a submeter, at Tenant’s
cost, to measure the electricity consumed by Tenant in connection with Tenant’s use of the Generator. Tenant’s use of the Tenant’s use of the Generator is not guaranteed and Landlord shall not be in default of this Lease in the event
Tenant is unable to use the Generator. 
 (2) Landlord shall repair and maintain the Generator, and Tenant shall pay one hundred percent
(100%) of the cost of such repair and maintenance. All such costs shall be deemed Rent under the Lease and shall be payable upon demand. 

(3) Tenant hereby agrees that Tenant’s connection to the Generator and its use of the Generator is at Tenant’s sole risk, and Tenant
hereby agrees that Landlord and the Indemnitees shall not be liable for, and Tenant hereby waives and releases all claims for loss or damage to Tenant’s business or damage to person or property sustained by Tenant or any person claiming by,
through or under Tenant, including Tenant’s principals, agents, contactors and employees, resulting from Tenant’s use of the Generator or connection to same, the failure of the Generator to operate properly, or the interruption or
cessation of electrical service from the Generator. 
 (4) Landlord may revoke Tenant’s right to connect to and use the Generator as
granted herein if Landlord determines, in its sole discretion, that (i) Tenant’s use of the Generator exceeds the capacity of the Generator, or (ii) Tenant is failing to perform its obligations with respect to the Generator, as
described in this Section 6.1(e), in a timely manner. Such revocation shall be by written notice and, upon receipt of such notice, Tenant shall have thirty (30) days to remedy the issue(s) stated in Landlord’s written notice. In the
event the Tenant cannot remedy such issue(s) within such 30-day period, Landlord, at Tenant’s sole cost and expense, shall disconnect the Generator infrastructure servicing the Premises. 

6.2 UTILITIES AND JANITORIAL SERVICES 
 All
utility services used in the production of heating and cooling and air supply and exhaust from the central HVAC systems serving the Building and Premises, including, without limitation, electricity and gas, as well as water and sewer services, shall
constitute Operating Expenses on the terms provided in the definition of Operating Expenses set forth above. All utility services used by Tenant within the Premises, including, without limitation, electricity and gas, shall be paid for by Tenant
either through a separate charge or as part of Operating Expenses. Such charges shall be based upon Tenant’s usage, which usage: (a) as to electricity, other than overhead lighting, shall be measured by a separate meter or sub-meter to be
installed as part of the Tenant Work, and paid by Tenant within fifteen (15) days after billing as additional Rent under this Lease; and (b) as to all other utilities, shall either be reasonably estimated by Landlord and paid by Tenant
within fifteen (15) days after billing as additional Rent under this Lease or included in Operating Expenses. In addition, Tenant shall provide its own janitorial services to the Premises, using a janitorial service reasonably acceptable to
Landlord or shall make arrangements with Landlord for Landlord, through Landlord’s vendors, to perform such Premises cleaning services, and shall pay the costs thereof directly to Landlord. Notwithstanding any provision of this Lease to the
contrary, Tenant shall not make any alterations or additions to the electric equipment or systems in the Premises, in each instance, without the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or
delayed so long as such alterations or additions (i) do not exceed the capacity of the wiring, feeders and risers in the Premises and (ii) are in compliance with the City’s building code. Tenant’s use of electric current shall at
no time exceed the capacity of the wiring, feeders and risers providing electric current to the Premises or the Building. The consent of Landlord to the installation of electric equipment shall not relieve Tenant from the obligation to limit usage
of electricity to no more than such capacity. 

  
 - 22 - 













 
6.3 ADDITIONAL AND AFTER HOUR SERVICES 
 At Tenant’s written request,
Landlord shall furnish additional quantities of any of the services or utilities specified in Section 6.1, if Landlord can reasonably do so, on the terms set forth herein. For services or utilities requested by Tenant and furnished by Landlord,
Tenant shall pay to Landlord as a charge therefor Landlord’s prevailing rates charged from time to time for such services and utilities, as additional Rent under this Lease. Without limiting the generality of the foregoing, for HVAC service
outside of Standard Operating Hours, Landlord’s prevailing rate as of the date of this Lease includes a one (I) hour minimum per activation. If Tenant shall fail to make any such payment, Landlord may, upon notice to Tenant and in addition
to Landlord’s other remedies under this Lease, discontinue any or all of such additional services. 
 6.4 TELEPHONE SERVICES 

All telephone and communication connections which Tenant may desire shall be subject to Landlord’s prior written approval, in
Landlord’s reasonable discretion, and the location of all Cables and the work in connection therewith shall be performed by contractors approved by Landlord and shall be subject to the direction of Landlord, except that such approval is not
required as to Tenant’s telephone equipment (including Cables) within the Premises and from the Premises in a route designated by Landlord to any telephone cabinet or panel provided (as existing) on Tenant’s floor for Tenant’s
connection to the Cables serving the Building so long as Tenant’s equipment does not require connections different than or additional to those to the telephone cabinet or panel provided. Except to the extent of such Cables within the Premises
or from the Premises to such telephone cabinet or panel, Landlord reserves the right to designate and control the entity or entities providing Cable installation, removal, repair and maintenance in the Building and to restrict and control access to
telephone cabinets or panels. In the event Landlord designates a particular vendor or vendors to provide such Cable installation, removal, repair and maintenance for the Building, Tenant agrees to abide by and participate in such program. Tenant
shall be responsible for and shall pay, as additional Rent under this Lease, all costs incurred in connection with the installation of Cables in the Premises, including any hook-up, access and maintenance fees related to the installation of such
Cables in the Premises and the commencement of service therein, and the maintenance thereafter of such Cables; and there shall be included in Operating Expenses for the Building all installation, removal, hook-up or maintenance costs incurred by
Landlord in connection with Cables serving the Building which are not allocable to any individual users of such service but are allocable to the Building generally. If Tenant fails to maintain all Cables in the Premises and such failure affects or
interferes with the operation or maintenance of any other Cables serving the Building, Landlord or any vendor hired by Landlord may enter into and upon the Premises forthwith and perform such repairs, restorations or alterations as Landlord deems
necessary in order to eliminate any such interference (and Landlord may recover from Tenant all of Landlord’s costs in connection therewith). If required by Landlord, no later than the Termination Date Tenant shall remove all Cables installed
by Tenant for and during Tenant’s occupancy. Tenant agrees that neither Landlord nor any of its agents or employees shall be liable to Tenant, or any of Tenant’s employees, agents, customers or invitees or anyone claiming through, by or
under Tenant, for any damages, injuries, losses, expenses, claims or causes of action because of any interruption, diminution, delay or discontinuance at any time for any reason in the furnishing of any telephone or other communication service to
the Premises and the Building. 
 6.5 DELAYS IN FURNISHING SERVICES 

Tenant agrees that Landlord shall not be in breach of this Lease nor be liable to Tenant for damages or otherwise, for any failure to furnish,
or a delay in furnishing, or a change in the quantity or character of any service when such failure, delay or change is occasioned, in whole or in part, by repairs, improvements or mechanical breakdowns, by the act or default of Tenant or other
parties or by an event of Force Majeure. No such failure, delay or change shall be deemed to be an eviction or disturbance of Tenant’s use and possession of the Premises, or relieve Tenant from paying Rent or from performing any other
obligations of Tenant under this Lease, without any deduction or offset, except as otherwise provided in this Section 6.5. Failure to any extent to make available, or any slowdown, stoppage, or interruption of, the specified utility services
resulting from any cause, including changes in service provider or Landlord’s compliance with any voluntary or similar governmental or business guidelines now or hereafter published or any requirements now or hereafter established by any
governmental agency, board, or bureau having jurisdiction over the operation of the Property, shall not render Landlord liable in any respect for damages to either persons, property, or business, nor be construed as an eviction of Tenant or work an
abatement of Rent, nor relieve Tenant of Tenant’s obligations for fulfillment of any covenant or agreement hereof. Should any equipment or machinery furnished by Landlord break down or for any cause cease to function properly, Landlord shall
use reasonable diligence to repair same promptly, but Tenant shall have no claim for abatement of Rent or damages on 

  
 - 23 - 













 
account of any interruption of service occasioned thereby or resulting therefrom. Notwithstanding anything to the contrary in the foregoing, if Tenant is unable to use the Premises as a result of
an interruption in service, and if any such interruption (i) continues for five (5) consecutive Business Days following Tenant’s delivery to Landlord of notice of such interruption, (ii) is caused by the negligence of Landlord or
any of its agents, employees, contractors, vendors or licensees, and the cure of same is within the reasonable control of Landlord (and is not attributable to any acts or omissions of Tenant or any third party or to Force Majeure),
(iii) materially and adversely affects Tenant’s ability to conduct business in the Premises, or any material portion thereof, and (iv) on account of such interruption Tenant ceases doing business in the Premises, Rent shall thereafter
abate to the extent the Premises are rendered unusable and are actually not used by Tenant as a result thereof, commencing on the sixth (6th) Business Day following Tenant’s notice hereunder and continuing for the remainder of the
interruption. Tenant hereby waives any benefits of any applicable existing or future Law, including the provisions of California Civil Code section 1932(1), permitting the termination of this Lease due to such interruption, failure or inability.

 6.6 CHOICE OF SERVICE PROVIDER 

Tenant acknowledges that Landlord may, at Landlord’s sole option, to the extent permitted by applicable Law, elect to change, from time to
time, the company or companies which provide services (including electrical service, gas service, water, telephone and technical services) to the Building, the Premises and/or its occupants. Notwithstanding anything to the contrary set forth in this
Lease, Tenant acknowledges that Landlord has not and does not make any representations or warranties concerning the identity or identities of the company or companies which provide services to the Building and the Premises or its occupants, and
Tenant acknowledges that the choice of service providers and matters concerning the engagement and termination thereof shall be solely that of Landlord. The foregoing provision is not intended to modify, amend, change or otherwise derogate any
provision of this Lease concerning the nature or type of service to be provided or any specific information concerning the amount thereof to be provided. Tenant agrees to cooperate with Landlord and each of its service providers in connection with
any change in service or provider. 
 6.7 SIGNAGE 

(a) Standard Signage. Initial Building standard signage for Tenant will be installed by Landlord in the directory in the main lobby of
the Building and, in the case of any multi-tenant floor, in the listing of tenants in the lobby for the floor on which the Premises is located and at Tenant’s main entry door to the Premises, all at Tenant’s sole cost and expense. Any
change in such initial signage shall be only with Landlord’s prior written consent, shall conform to Building standard signage and shall be at Tenant’s sole cost and expense. 

(b) Exterior Signs. In addition to the signage identified in Section 6.7(a) above, Tenant shall, in accordance with the Aquatic
Park Center Campus signage program (the “Aquatic Park Center Campus Signage Program”), continue to have the exclusive right to keep and maintain a sign panel displaying Tenant’s trade name on the monument sign located at the southeast
corner of the Project (i.e., Ninth and Potter) (the “Exclusive Monument Sign”) and the non-exclusive right to keep and maintain a sign panel displaying Tenant’s trade name on the monument signs located at Seventh and Potter and
Seventh and Anthony, respectively (the “Non-Exclusive Monument Sign”, and collectively with the Exclusive Monument Sign, the “Monument Signs”). Landlord shall have no obligation to Tenant with respect to the adequacy or condition
of the existing Monument Sign structures except ordinary repairs and maintenance of the structure containing the Non-Exclusive Monument Sign, and Landlord has not made any warranty or representation of any kind to Tenant regarding the condition of
the existing Monument Sign structures. Notwithstanding anything to the contrary contained in this Lease, and in addition to the maintenance and repair obligations of Tenant set forth in Section 8.2 of this Lease, any and all maintenance and
repair relating to Tenant’s sign panels on the Monument Signs, and the structure containing the Exclusive Monument Sign (including, without limitation, upgrading such structure to conform to the Aquatic Park Center Campus Signage Program),
shall be the sole responsibility of Tenant and at Tenant’s sole cost. Notwithstanding anything to the contrary contained herein, Tenant’s rights under this Section 6.7 are personal to the Named Tenant and any Permitted Transferee and
shall not be assigned or assignable, in whole or in part, to any third party other than a Permitted Transferee.

 (e) Tenant agrees to reasonably cooperate with Landlord and lo comply at
no material cost to Tenant with any and all guidelines or controls concerning energy management and usage disclosure imposed upon Landlord by federal or state governmental organizations or by any energy conservation association to which Landlord is

to time so much of the data collected and maintained by it regarding Tenant’s energy consumption data as may be necessary to cause the Building to participate in the ENERGY STAR®
Portfolio Manager system and similar programs; and Tenant further authorizes Landlord to disclose information concerning energy use by Tenant, either individually or in combination with the energy use of other tenants, as applicable as Landlord
determines to be necessary to comply with applicable Laws pertaining to the Building or Landlord’s ownership thereof.

Landlord with a written notice thereof, Landlord shall promptly after receipt of written notice from Tenant setting forth with specificity the nature and extent of such noncompliance, rectify the same at Landlord’s expense; such noncompliance
shall not, however, entitle Tenant to an abatement of rent or to terminate this Lease, or otherwise release Tenant from any of Tenant’s obligations under this Lease.

whether to the Premises or to the Building caused by the negligence of Tenant, its employees, agents, servants, licensees, subtenants, contractors or invitees, shall be paid by Tenant, subject to the waivers set forth in Section 16.4. Landlord
shall not be liable to Tenant for any expense, injury, loss or damage resulting from work done in or upon, or in connection with the use of, any adjacent or nearby building, land, street or alley.

 8.2 TENANT’S MAINTENANCE 

Tenant shall periodically inspect the Premises to identify any conditions that are dangerous or in need of maintenance, repair or replacement.
Subject to the provisions of Article 14 and Section 16.4, Tenant shall promptly provide Landlord with notice of any such conditions. Tenant shall, at its sole cost and expense, perform all maintenance, repair and replacement of the Premises
that are not Landlord’s express responsibility under this Lease, and keep the Premises in good condition and repair, reasonable wear and tear excepted. Tenant’s maintenance, repair and replacement obligations include, without limitation,
maintenance, repairs and replacements of: (a) floor covering; (b) interior partitions; (c) doors; (d) the interior side of demising walls; (e) electronic, phone and data cabling, wiring and related equipment that is
installed by or for the exclusive benefit of Tenant (collectively, “Cable”); (f) supplemental air conditioning units, kitchens, including hot water heaters, plumbing, and similar facilities exclusively serving Tenant; and
(g) Tenant Alterations. Landlord shall allocate one hundred percent (100%) of the cost (plus any applicable administration fees) of Landlord’s maintenance, repair or replacement of any Tenant Alterations (if such maintenance, repair
or replacement is requested by Tenant), or repairs or replacements required to areas outside of the Premises due to same, to Tenant as additional Rent under this Lease. All maintenance, repairs and replacements, including, but not limited to,
janitorial and cleaning services, pest control and waste management and recycling performed by or on behalf of Landlord or Tenant must comply with the Project’s Sustainability Practices and Tenant is strongly encouraged to comply with the
applicable Green Building Standards. If Tenant fails to make any repairs or replacements of the Premises under this Section 8.2 and the same shall constitute a Default under Section 11.1(e), Landlord may make the repairs or replacements,
and Tenant shall pay, as additional Rent under this Lease, the reasonable cost of the repairs or replacements, together with an administrative charge in an amount equal to 10% of the cost of the repairs or replacements. Tenant hereby waives all
right to make repairs or replacements at the expense of Landlord or in lieu thereof to vacate the Premises and its other similar rights as provided in California Civil Code Sections 1932(1), 1941 and 1942 or any other Laws (whether now or hereafter
in effect). In addition to the foregoing, Tenant shall be responsible for all costs in connection with maintaining, repairing and replacing all special tenant fixtures and improvements, including garbage disposals, showers, plumbing, water
filtration systems and appliances. If Tenant requests that Landlord maintain, repair and/or replace any such fixtures and improvements, Tenant shall reimburse Landlord for the cost of all such maintenance, repair and replacement work, plus an
administrative fee equal to 15% of such cost, as additional Rent under this Lease, and Landlord’s liability for such maintenance, repair and replacement work shall be subject to and limited by the provisions of Article 17 below. 

ARTICLE 9 
 ALTERATIONS AND
IMPROVEMENTS 
 9.1 TENANT ALTERATIONS 

(a) The following provisions shall apply to the completion of any Tenant Alterations: 

(1) Tenant shall not, except as provided herein, without the prior written consent of Landlord, which consent shall not be unreasonably
withheld, make or cause to be made any Tenant Alterations in or to the Premises or any Property systems serving the Premises. Prior to making any Tenant Alterations, Tenant shall give Landlord ten (I 0) days prior written notice (or such earlier
notice as would be necessary pursuant to applicable Law) to permit Landlord sufficient time to post appropriate notices of non-responsibility. Subject to all other requirements of this Article 9, Tenant may undertake Decoration work without
Landlord’s prior written consent. Tenant shall furnish Landlord with the names and addresses of all contractors and subcontractors and copies of all contracts. All Tenant Alterations shall be completed at such reasonable times and in such
manner as Landlord may from time to time designate, and only by contractors or mechanics approved by Landlord, which approval shall not be unreasonably withheld; provided, however, that Landlord may, in its sole discretion, specify the engineers and
contractors to perform all work relating to the Building’s systems (including the mechanical, heating, plumbing, security, ventilating, air-conditioning, electrical, communication and the fire and life safety systems in the Building). The
contractors, mechanics and engineers who may be used are further limited to those whose work will not cause or threaten to cause disharmony or interference with Landlord or other tenants in the Building and their respective agents and contractors


  
 - 34 - 













 
performing work in or about the Building. Landlord may further condition its consent upon Tenant furnishing to Landlord and Landlord approving prior to the commencement of any work or delivery of
materials to the Premises related to the Tenant Alterations such of the following as specified by Landlord: architectural plans and specifications, opinions from Landlord’s engineers stating that the Tenant Alterations will not in any way
adversely affect the Building’s systems, necessary permits and licenses, certificates of insurance, and such other documents in such form reasonably requested by Landlord. Landlord may, in the exercise of reasonable judgment, request that
Tenant provide Landlord with appropriate evidence of Tenant’s ability to complete and pay for the completion of the Tenant Alterations such as a performance bond or letter of credit. Upon completion of the Tenant Alterations, Tenant shall
deliver to Landlord an as-built digitized set of plans and specifications for the Tenant Alterations in both protected document(“.pdf’’) and computer-aided design (“CAD”) formats. 

(2) Tenant shall pay the cost of all Tenant Alterations and the cost of decorating the Premises and any work to the Property occasioned
thereby. Upon completion of Tenant Alterations, Tenant shall furnish Landlord with contractors’ affidavits and full and final waivers of lien and receipted bills covering all labor and materials expended and used in connection therewith and
such other documentation reasonably requested by Landlord or Mortgagee. 
 (3) Tenant agrees to complete all Tenant Alterations (i) in
accordance with all Laws, Hazardous Materials Laws, all requirements of applicable insurance companies and in accordance with Landlord’s standard construction rules and regulations, (ii) in a good and workmanlike manner with the use of
good grades of materials, and (iii) in accordance with the requirements of the Project’s Sustainability Practices. Tenant is strongly encouraged to comply with the applicable Green Building Standards. Tenant shall notify Landlord
immediately if Tenant receives any notice of violation of any Law in connection with completion of any Tenant Alterations and shall immediately take such steps as are necessary to remedy such violation. In no event shall such supervision or right to
supervise by Landlord nor shall any approvals given by Landlord under this Lease constitute any warranty by Landlord to Tenant of the adequacy of the design, workmanship or quality of such work or materials for Tenant’s intended use or of
compliance with the requirements of Section 9.1(a)(3)(i) and (ii) above or impose any liability upon Landlord in connection with the performance of such work. 

(b) For any Tenant Alterations which Tenant requests Landlord to install, the forgoing provisions of this Section 9.1 shall apply;
provided, however, in addition to paying the cost of the Tenant Alterations, Tenant also shall pay an administrative fee equal to fifteen percent (15%) of such cost to Landlord, as additional Rent under this Lease, and Landlord’s liability
for such Tenant Alterations work shall be subject to and limited by the provisions of Article 17 below. All Tenant Additions, whether installed by Landlord or Tenant, shall without compensation or credit to Tenant, become part of the Premises and
the property of Landlord at the time of their installation and shall remain in the Premises, unless pursuant to Article 12, Tenant may remove them or is required to remove them at Landlord’s request. 

9.2 LIENS 
 Tenant shall not permit any
lien or claim for lien of any mechanic, laborer or supplier or any other lien to be filed against the Building, the Land, the Premises, or any other part of the Property arising out of work performed, or alleged to have been performed by, or at the
direction of, or on behalf of Tenant. If any such lien or claim for lien is filed, Tenant shall within ten (I 0) days after receiving notice of such lien or claim (a) have such lien or claim for lien released of record or (b) deliver to
Landlord a bond in form, content, amount, and issued by surety, satisfactory to Landlord, indemnifying, protecting, defending and holding harmless the Indemnitees against all costs and liabilities resulting from such lien or claim for lien and the
foreclosure or attempted foreclosure thereof. If Tenant fails to take any of the above actions, Landlord, in addition to its rights and remedies under Article 11, without investigating the validity of such lien or claim for lien, may pay or
discharge the same and Tenant shall, as payment of additional Rent hereunder, reimburse Landlord upon demand for the amount so paid by Landlord, including Landlord’s expenses and attorneys’ fees.

 ARTICLE 10 

ASSIGNMENT AND SUBLETTING 
 10.1
ASSIGNMENT AND SUBLETTING 
 (a) Without the prior written consent of Landlord, which consent of Landlord shall not be unreasonably
withheld, conditioned or delayed, Tenant may not sublease, assign, mortgage, pledge, hypothecate or otherwise transfer or permit the transfer of this Lease or the encumbering of Tenant’s interest therein in whole or in part, by operation of Law
or otherwise or permit the use or occupancy of the Premises, or any part thereof, by anyone other than Tenant. Tenant agrees that the provisions governing sublease and assignment set forth in this Article 10 shall be deemed to be reasonable. If
Tenant desires to enter into any sublease of the Premises or assignment of this Lease, Tenant shall deliver written notice thereof to Landlord (“Tenant’s Notice”), together with the identity of the proposed subtenant or assignee and
the proposed principal terms thereof and financial and other information sufficient for Landlord to make an informed judgment with respect to such proposed subtenant or assignee at least forty-five (45) days prior to the commencement date of
the term of the proposed sublease or assignment. If Tenant proposes to sublease less than all of the Rentable Area of the Premises, the space proposed to be sublet and the space retained by Tenant must each be a marketable unit as reasonably
determined by Landlord and otherwise in compliance with all Laws. Landlord shall notify Tenant in writing of its approval or disapproval of the proposed sublease or assignment or its decision to exercise its rights under Section 10.2 within
thirty (30) days after receipt of Tenant’s Notice (and all required information). In no event may Tenant sublease any portion of the Premises or assign the Lease to any other tenant of the Project. Tenant shall submit for Landlord’s
approval (which approval shall not be unreasonably withheld) any advertising which Tenant or its agents intend to use with respect to the space proposed to be sublet. 

(b) With respect to Landlord’s consent to an assignment or sublease, Landlord may take into consideration any factors that Landlord may
deem relevant, and the reasons for which Landlord’s denial shall be deemed to be reasonable shall include, without limitation, the following: 

(i) the creditworthiness of any proposed subtenant or assignee is not acceptable to Landlord; or 

(ii) in Landlord’s reasonable judgment the proposed assignee or sublessee would diminish the value or reputation of the Project, Campus
or Landlord; or 
 (iii) any proposed assignee’s or sublessee’s use of the Premises would violate Section 7.1 of this Lease
or would violate the provisions of any other leases of tenants in the Project; or 
 (iv) the proposed sublessee or assignee is a current
occupant of the Project or Campus or a bona fide prospective tenant of Landlord in the Project as demonstrated by a written proposal dated within six (6) months prior to the date of Tenant’s request and Landlord has vacancy in the Project
of a similar size and finish as the space subject to such proposed sublease or assignment; or 
 (v) the proposed sublessee or assignee
would materially increase the estimated pedestrian and vehicular traffic to and from the Premises and the Project above that reasonably deemed typical by Landlord for office/lab use in the Project; or 

(vi) Tenant is in Default under this Lease. 

(c) Any sublease or assignment shall be expressly subject to the terms and conditions of this Lease. Any subtenant or assignee shall execute
such documents as Landlord may reasonably require to evidence such subtenant or assignee’s assumption of the obligations and liabilities of Tenant under this Lease. Tenant shall deliver to Landlord a copy of all agreements executed by Tenant
and the proposed subtenant and assignee with respect to the Premises. Landlord’s approval of a sublease, assignment, hypothecation, transfer or third party use or occupancy shall not constitute a waiver of Tenant’s obligation to obtain
Landlord’s consent to further assignments or subleases, hypothecations, transfers or third party use or occupancy. 

  
 - 36 - 













 (d) For purposes of this Article 10, an assignment shall be deemed to include a change in
the majority control of Tenant resulting from any transfer, sale or assignment of shares of stock of Tenant occurring by operation of Law or otherwise (other than an Excluded Change In Majority Control, as defined below) if Tenant is a corporation
whose shares of stock are not traded publicly. If Tenant is a general partnership, any change in the general partners of Tenant shall be deemed to be an assignment for purposes of this Lease. As used herein, an “Excluded Change in Majority
Control” shall mean any change in the majority control of Tenant resulting from or associated with (i) any initial public offering of the capital stock or other equity interest of Tenant on any nationally recognized securities exchange or
(ii) any bona fide capitalization, recapitalization or financing for the benefit of Tenant (a “Financing Event”); provided, however, in the case of a Financing Event, Tenant shall give Landlord written notice at least fifteen
(15) days prior to the effective date of the Financing Event, together with evidence that Tenant shall continue to have a net worth equal to or greater than Tenant’s net worth as of the date immediately prior to the Financing Event, or if
prior notice is prohibited by a confidentiality agreement or securities regulations or related regulations, then as soon after the Financing Event as is permissible. 

(e) o long as Tenant is not entering into a transaction described herein for the purpose of avoiding or otherwise circumventing the remaining
terms of this Article, Tenant may, subject to Section 10.5, assign its entire interest under this Lease or sublease all or a portion of the Premises, without the consent of Landlord, to any of the following (each, a “Permitted
Transferee”) (i) an Affiliate, or (ii) a successor to Tenant by purchase or other acquisition of Tenant’s capital stock or substantially all of Tenant’s assets or by merger, consolidation or reorganization, provided that all
of the following conditions are satisfied: (1) Tenant is not then in Default under this Lease; (2) Tenant shall give Landlord written notice at least fifteen (15) days prior to the effective date of the proposed transfer together with
the information required hereunder and such entity shall expressly assume Tenant’s obligations hereunder, or if prior notice is prohibited by a confidentiality agreement or securities regulations or related regulations, then as soon after the
transfer as is permissible; (3) with respect to an assignment to an Affiliate, Tenant continues to have a net worth equal to or greater than Tenant’s net worth as of the date immediately prior to such transfer; and (4) with respect to
a purchase, merger, consolidation or reorganization which results in Tenant ceasing to exist as a separate legal entity, Tenant’s successor shall have a net worth equal to Tenant’s net worth at the date immediately prior to such transfer.

 (f) Notwithstanding anything in this Section 10.1 to the contrary, Tenant shall be permitted to allow its contractors (i.e., parties
with whom Tenant contracts to provide special services, such as scientists) to occupy certain portions of the Premises without Landlord’s consent (for purposes of this Section 10.1(g), each such, person or company is referred to as an
“Occupant”), provided the following conditions are satisfied: (i) such occupancy is not a subterfuge to avoid the provisions of this Article 10 concerning assignment and subleases; (ii) such occupancy is not separated from the
remaining portions of the Premises by demising walls and does not have a separate entrance; (iii) each Occupant shall comply with the insurance requirements under Sections 16.1 and 16.2 (including naming Landlord and the Indemnitees required
under Section 16.2 as additional insureds) as if such Occupant were Tenant (with Landlord having received evidence of such insurance prior to such Occupant’s occupancy of the Premises) and shall be subject to the waivers under
Section 16.4 as if such Occupant were Tenant; (iv) prior to such Occupant’s occupancy of the Premises, Tenant shall have provided Landlord with the name and address of the Occupant and length of occupancy term for such Occupant; and
(v) the aggregate space occupied by Occupants at any time does not exceed 1,000 rentable square feet. If an occupancy described above does not satisfy all of the foregoing conditions, then such occupancy shall constitute a sublease and shall be
subject to the other provisions of this Section 10.1. 
 10.2 RECAPTURE 

Excluding any assignment or sublease contemplated in Section 10.1(e), Landlord shall have the option to exclude from the Premises covered
by this Lease (“recapture”) the space proposed to be sublet for substantially the remainder of the Term or subject to the assignment, effective as of the proposed commencement date of such sublease or assignment. If Landlord elects to
recapture, Tenant shall surrender possession of the space proposed to be subleased or subject to the assignment to Landlord on the effective date of recapture of such space from the Premises, such date being the Termination Date for such space.
Effective as of the date of recapture of any portion of the Premises pursuant to this section, the Monthly Base Rent, Rentable Area of the Premises and Tenant’s Share shall be adjusted accordingly. 

  
 - 37 - 













 10.3 EXCESS RENT 

Tenant shall pay Landlord on the first day of each month during the term of the sublease or assignment, as additional Rent under this Lease,
fifty percent (50%) of the amount by which the sum of all rent and other consideration (direct or indirect) due from the subtenant or assignee for such month exceeds: (i) that portion of the Monthly Base Rent and Rent Adjustments due under
this Lease for said month which is allocable to the space sublet or assigned; and (ii) the following costs and expenses for the subletting or assignment of such space: (I) brokerage commissions and attorneys’ fees and expenses,
(2) the actual costs paid in making any improvements or substitutions in the Premises required by any sublease or assignment; (3) “free rent” periods, costs of any inducements or concessions given to subtenant or assignee; and
(4) reasonable moving costs and other amounts actually paid with respect to such subtenant’s or assignee’s other leases or occupancy arrangements. All such costs and expenses shall be amortized over the term of the sublease or
assignment pursuant to sound accounting principles. 
 10.4 TENANT LIABILITY 

In the event of any sublease or assignment, whether or not with Landlord’s consent, Tenant shall not be released or discharged from any
liability, whether past, present or future, under this Lease, including any liability arising from the exercise of any renewal or expansion option, to the extent such exercise is expressly permitted by Landlord. Tenant’s liability shall remain
primary, and in the event of default by any subtenant, assignee or successor of Tenant in performance or observance of any of the covenants or conditions of this Lease, Landlord may proceed directly against Tenant without the necessity of exhausting
remedies against said subtenant, assignee or successor. After any assignment, Landlord may consent to subsequent assignments or subletting of this Lease, or amendments or modifications of this Lease with assignees of Tenant, without notifying
Tenant, or any successor of Tenant, and without obtaining its or their consent thereto, and such action shall not relieve Tenant or any successor of Tenant of liability under this Lease. If Tenant has any options to extend the Term or to add other
space to the Premises, except with respect to a Permitted Transferee, such options shall not be available to any subtenant or assignee, directly or indirectly without Landlord’s express written consent, which may be withheld in Landlord’s
sole discretion. 
 10.5 ASSUMPTION AND ATTORNMENT 

If Tenant shall assign this Lease as permitted herein, the assignee shall expressly assume all of the obligations of Tenant hereunder accruing
after the effective date of the assignment in a written instrument satisfactory to Landlord and furnished to Landlord not later than thirty (30) days prior to the effective date of the assignment. Each sublease by Tenant hereunder shall be
subject and subordinate to this Lease and to the matters to which this Lease is or shall be subordinate, and each subtenant by entering into a sublease is deemed to have agreed that in the event of termination, re-entry or dispossession by Landlord
under this Lease, Landlord may, at its option, either terminate the sublease or take over all of the right, title and interest of Tenant, as sublandlord, under such sublease, and such subtenant shall, at Landlord’s option, attorn to Landlord
pursuant to the then executory provisions of such sublease, except that Landlord shall not be: (I) liable for any previous act or omission of Tenant under such sublease; (2) subject to any counterclaim, offset or defense that such
subtenant might have against Tenant; (3) bound by any previous modification of such sublease or by any rent or additional rent or advance rent which such subtenant might have paid for more than the current month to Tenant, and all such rent
shall remain due and owing, notwithstanding such advance payment; (4) bound by any security or advance rental deposit made by such subtenant which is not delivered or paid over to Landlord and with respect to which such subtenant shall look
solely to Tenant for refund or reimbursement; or (5) obligated to perform any work in the subleased space or to prepare it for occupancy, and in connection with such attornment, the subtenant shall execute and deliver to Landlord any
instruments Landlord may reasonably request to evidence and confirm such attornment. Each subtenant or licensee of Tenant shall be deemed, automatically upon and as a condition of its occupying or using the Premises or any part thereof, to have
agreed to be bound by the terms and conditions set forth in this Section 10.5. The provisions of this Section 10.5 shall be self-operative, and no further instrument shall be required to give effect to this provision. 

10.6 PROCESSING EXPENSES 
 Tenant shall pay
to Landlord, as Landlord’s cost of processing each proposed assignment or subletting (whether or not the same is ultimately approved by Landlord or consummated by Tenant), the sum of One Thousand Five Hundred Dollars ($1,500.00), plus all
reasonable attorneys’ fees and expenses incurred by Landlord with respect to such proposed assignment or sublease, which attorneys’ fees and expenses shall not exceed $3,000.00 

  
 - 38 - 













 
(collectively, “Processing Costs”); provided, however, that Tenant shall pay to Landlord any additional reasonable attorneys’ fees and expenses incurred by Landlord to the extent
Tenant or its proposed assignee or subtenant does not execute Landlord’s standard form of consent. Notwithstanding anything to the contrary herein, Landlord shall not be required to process any request for Landlord’s consent to an
assignment or subletting until Tenant has paid to Landlord the amount of Landlord’s estimate of the Processing Costs. When the actual amount of the Processing Costs is determined, it shall be reconciled with Landlord’s estimate, and any
payments or refunds required as a result thereof shall promptly thereafter be made by the parties. 
 ARTICLE 11 

DEFAULT AND REMEDIES 
 11.1 DEFAULT

 The occurrence or existence of any one or more of the following shall constitute a “Default” by Tenant under this Lease: 

(a) Tenant fails to pay any installment or other payment of Rent including Rent Adjustment Deposits or Rent Adjustments within five
(5) days after the date when due; 
 (b) Tenant abandons the Premises; 

(c) Tenant violates the restrictions on assignments and subleases set forth in Article 10 Assignment and Subletting and fails to cure such
default within five (5) Business Days after receipt of written notice thereof from Landlord; 
 (d) Tenant fails to maintain any
insurance policy required of it hereunder, and fails to cure such default within five (5) Business Days after receipt of written notice thereof from Landlord; 

(e) Tenant fails to observe or perform any of the other covenants, conditions or provisions of this Lease or the Workletter and fails to cure
such default within thirty (30) days after written notice thereof to Tenant, or such longer time as may reasonably be required to cure the default, so long as Tenant commences such cure within thirty (30) days after written notice thereof
and diligently pursues such cure to completion unless the failure to perform is a Default for which this Lease expressly specifies there is no cure or grace period; 

(f) the interest of Tenant in this Lease is levied upon under execution or other legal process; 

(g) a petition is filed by or against Tenant to declare Tenant bankrupt or seeking a plan of reorganization or arrangement under any Chapter of
the Bankruptcy Code, or any amendment, replacement or substitution therefor, or to delay payment of, reduce or modify Tenant’s debts, which in the case of an involuntary action is not discharged within thirty (30) days; 

(h) Tenant is declared insolvent by Law or any assignment of Tenant’s property is made for the benefit of creditors; 

(i) a receiver is appointed for Tenant or Tenant’s property, which appointment is not discharged within thirty (30) days; 

(j) any action taken by or against Tenant to reorganize or modify Tenant’s capital structure in a materially adverse way which in the case
of an involuntary action is not discharged within thirty (30) days; 
 (k) upon the dissolution of Tenant; or 

(l) upon the third occurrence during any twelve (12)-month period during the Term that Tenant fails to pay Rent when due or has breached a
particular covenant of this Lease (whether or not such failure or breach is thereafter cured within any stated cure or grace period or statutory period). 

  
 - 39 - 













 11.2 LANDLORD’S REMEDIES 

(a) A Default shall constitute a breach of this Lease for which Landlord shall have the rights and remedies set forth in this Section 11.2
and all other rights and remedies set forth in this Lease or now or hereafter allowed by Law, whether legal or equitable, and all rights and remedies of Landlord shall be cumulative and none shall exclude any other right or remedy now or hereafter
allowed by applicable Law. 
 (b) With respect to a Default, at any time Landlord may terminate Tenant’s right to possession by written
notice to Tenant stating such election. Any written notice required pursuant to Section 11.1 shall constitute notice of unlawful detainer pursuant to California Code of Civil Procedure Section 1161 if, at Landlord’s sole discretion,
it states Landlord’s election that Tenant’s right to possession is terminated after expiration of any period required by Law or any longer period required by Section 11.1. Upon the expiration of the period stated in Landlord’s
written notice of termination (and unless such notice provides an option to cure within such period and Tenant cures the Default within such period), Tenant’s right to possession shall terminate and this Lease shall terminate, and Tenant shall
remain liable as hereinafter provided. Upon such termination in writing of Tenant’s right to possession, Landlord shall have the right, subject to applicable Law, to re-enter the Premises and dispossess Tenant and the legal representatives of
Tenant and all other occupants of the Premises by unlawful detainer or other summary proceedings, or as otherwise permitted by Law, regain possession of the Premises and remove their property (including their trade fixtures, personal property and
Required Removables pursuant to Article 12), but Landlord shall not be obligated to effect such removal, and such property may, at Landlord’s option, be stored elsewhere, sold or otherwise dealt with as permitted by Law, at the risk of, expense
of and for the account of Tenant, and the proceeds of any sale shall be applied pursuant to Law. Landlord shall in no event be responsible for the value, preservation or safekeeping of any such property. Tenant hereby waives all claims for damages
that may be caused by Landlord’s removing or storing Tenant’s personal property pursuant to this Section or Section 12.1, and Tenant hereby indemnifies, and agrees to defend, protect and hold harmless, the Indemnitees from any and all
loss, claims, demands, actions, expenses, liability and cost (including attorneys’ fees and expenses) arising out of or in any way related to such removal or storage. Upon such written termination of Tenant’s right to possession and this
Lease, Landlord shall have the right to recover damages for Tenant’s Default as provided herein or by Law, including the following damages provided by California Civil Code Section 1951.2: 

(1) the worth at the time of award of the unpaid Rent which had been earned at the time of termination; 

(2) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of
award exceeds the amount of such Rent loss that Tenant proves could reasonably have been avoided; 
 (3) the worth at the time of award of
the amount by which the unpaid Rent for the balance of the term of this Lease after the time of award exceeds the amount of such Rent loss that Tenant proves could be reasonably avoided; and 

(4) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its
obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, including, without limitation, Landlord’s unamortized costs of tenant improvements, leasing commissions and legal fees incurred in
connection with entering into this Lease; and 
 The word “rent” as used in this Section 11.2 shall have the same meaning as
the defined term Rent in this Lease. The “worth at the time of award” of the amount referred to in clauses (I) and (2) above is computed by allowing interest at the Default Rate. The worth at the time of award of the amount
referred to in clause (3) above is computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (I%). For the purpose of determining unpaid Rent under clause
(3) above, the monthly Rent reserved in this Lease shall be deemed to be the sum of the Monthly Base Rent, monthly storage space rent, if any, the amounts last payable by Tenant as Rent Adjustments for the calendar year in which Landlord
terminated this Lease as provided hereinabove. 

  
 - 40 - 













 (c) Even if Tenant is in Default and/or has abandoned the Premises, this Lease shall
continue in effect for so long as Landlord does not terminate Tenant’s right to possession by written notice as provided in Section 11.2(b) above, and Landlord may enforce all its rights and remedies under this Lease, including the right
to recover Rent as it becomes due under this Lease. In such event, Landlord shall have all of the rights and remedies of a landlord under California Civil Code Section 1951.4 (lessor may continue Lease in effect after lessee’s breach and
abandonment and recover Rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations), or any successor statute. During such time as Tenant is in Default, if Landlord has not terminated this Lease by
written notice and if Tenant requests Landlord’s consent to an assignment of this Lease or a sublease of the Premises, such consent shall be governed by the terms and conditions of Article 10 above. Tenant acknowledges and agrees that the
provisions of Article 10 shall be deemed to constitute reasonable limitations of Tenant’s right to assign or sublet. Tenant acknowledges and agrees that in the absence of written notice pursuant to Section 11.2(b) above terminating
Tenant’s right to possession, no other act of Landlord shall constitute a termination of Tenant’s right to possession or an acceptance of Tenant’s surrender of the Premises, including acts of maintenance or preservation or efforts to
relet the Premises or the appointment of a receiver upon initiative of Landlord to protect Landlord’s interest under this Lease or the withholding of consent to a subletting or assignment, or terminating a subletting or assignment, if in
accordance with other provisions of this Lease. 
 (d) In the event that Landlord seeks an injunction with respect to a breach or threatened
breach by Tenant of any of the covenants, conditions or provisions of this Lease, Tenant agrees to pay the premium for any bond required in connection with such injunction. 

(e) Tenant hereby waives any and all rights to relief from forfeiture, redemption or reinstatement granted by Law (including California Civil
Code of Procedure Sections 1174 and 1179) in the event of Tenant being evicted or dispossessed for any cause or in the event of Landlord obtaining possession of the Premises by reason of Tenant’s Default or otherwise. 

(f) Notwithstanding any other provision of this Lease, a notice to Tenant given under this Article and Article 24 of this Lease or given
pursuant to California Code of Civil Procedure Section 1161, and any notice served by mail, shall be deemed served, and the requisite waiting period deemed to begin under said Code of Civil Procedure Section upon mailing (except as may be
required under Code of Civil Procedure Section 1161 et seq.), without any additional waiting requirement under Code of Civil Procedure Section 1011 et seq. or by other Law. For purposes of Code of Civil Procedure Section 1162,
Tenant’s “place of residence”, “usual place of business”, “the property” and “the place where the property is situated” shall mean and be the Premises, whether or not Tenant has vacated same at the time
of service. 
 (g) The voluntary or other surrender or termination of this Lease, or a mutual termination or cancellation thereof, shall not
work a merger and shall terminate all or any existing assignments, subleases, subtenancies or occupancies permitted by Tenant, except if and as otherwise specified in writing by Landlord. 

(h) No delay or omission in the exercise of any right or remedy of Landlord upon any default by Tenant, and no exercise by Landlord of its
rights pursuant to Section 25.16 to perform any duty which Tenant fails timely to perform, shall impair any right or remedy or be construed as a waiver. No provision of this Lease shall be deemed waived by Landlord unless such waiver is in
writing signed by Landlord. The waiver by Landlord of any breach of any provision of this Lease shall not be deemed a waiver of any subsequent breach of the same or any other provision of this Lease. 

11.3 ATTORNEY’S FEES 
 In the event

addition to such other relief as may be awarded, be entitled to recover attorneys’ fees, expenses and costs of investigation as actually incurred, including court costs, expert witness fees, costs and expenses of investigation, and all

 11.4 BANKRUPTCY 

The following provisions shall apply in the event of the bankruptcy or insolvency of Tenant: 

(a) In connection with any proceeding under Chapter 7 of the Bankruptcy Code where the trustee of Tenant elects to assume this Lease for the
purposes of assigning it, such election or assignment, may only be made upon compliance with the provisions of (b) and (c) below, which conditions Landlord and Tenant acknowledge to be commercially reasonable. In the event the trustee
elects to reject this Lease, then Landlord shall immediately be entitled to possession of the Premises without further obligation to Tenant or the trustee. 

(b) Any election to assume this Lease under Chapter 11 or 13 of the Bankruptcy Code by Tenant as debtor-in-possession or by Tenant’s
trustee (the “Electing Party”) must provide for: 
 The Electing Party to cure or provide to Landlord adequate assurance that it
will cure all monetary defaults under this Lease within fifteen (15) days from the date of assumption, and that it will cure all nonmonetary defaults under this Lease within thirty (30) days from the date of assumption. Landlord and Tenant
acknowledge such condition to be commercially reasonable. 
 (c) If the Electing Party has assumed this Lease or elects to assign
Tenant’s interest under this Lease to any other person, such interest may be assigned only if the intended assignee has provided adequate assurance of future performance (as herein defined), of all of the obligations imposed on Tenant under
this Lease. 
 For the purposes hereof, “adequate assurance of future performance” means that Landlord has ascertained that each
of the following conditions has been satisfied: 
 (i) The assignee has submitted a current financial statement, certified by its chief
financial officer, which shows a net worth and working capital in amounts sufficient to assure the future performance by the assignee of Tenant’s obligations under this Lease; and 

(ii) Landlord has obtained consents or waivers from any third parties that may be required under a lease, mortgage, financing arrangement, or
other agreement by which Landlord is bound, to enable Landlord to permit such assignment. 
 (d) Landlord’s acceptance of rent or any
other payment from any trustee, receiver, assignee, person, or other entity will not be deemed to have waived, or waive, the requirement of Landlord’s consent, Landlord’s right to terminate this Lease for any transfer of Tenant’s
interest under this Lease without such consent, or Landlord’s claim for any amount of Rent due from Tenant. 
 11.5 LANDLORD’S DEFAULT 

Landlord shall be in default hereunder in the event Landlord has not commenced and pursued with reasonable diligence the cure of any failure of
Landlord to meet its obligations hereunder within thirty (30) days after the receipt by Landlord of written notice from Tenant of the alleged failure to perform. Failure to provide the requisite notice and cure period by Tenant under this
paragraph shall be an absolute defense by Landlord against any claims for failure to perform any of its obligations. In no event shall Tenant have the right to terminate or rescind this Lease as a result of Landlord’s default as to any covenant
or agreement contained in this Lease. Tenant hereby waives such remedies of termination and rescission and hereby agrees that Tenant’s remedies for default hereunder and for breach of any promise or inducement shall be limited to a suit for
damages and/or injunction. In addition, Tenant hereby covenants that, prior to the exercise of any such remedies, it will give any Mortgagee notice and a reasonable time to cure any default by Landlord (as specified in Section 23.2 below).

 ARTICLE 12 

SURRENDER OF PREMISES 
 12.1 IN
GENERAL 
 Upon the Termination Date, Tenant shall surrender and vacate the Premises immediately and deliver possession thereof to
Landlord in a clean, good and tenantable condition, ordinary wear and tear, Hazardous Materials (other than those which are Tenant’s responsibility hereunder), casualty and condemnation, and damage caused by Landlord excepted. Tenant shall
deliver to Landlord all keys to the Premises. All improvements in and to the Premises, including any Tenant Alterations (collectively, “Leasehold Improvements”) shall remain upon the Premises at the end of the Term without compensation to
Tenant. Tenant’s trade fixtures, furniture, equipment and other personal property installed in the Premises (“Tenant’s Property”) shall at all times be and remain Tenant’s property. Except for Alterations which cannot be
removed without structural injury to the Premises, at any time Tenant may remove Tenant’s Property from the Premises, provided that Tenant repairs all damage caused by such removal. Landlord shall have no lien or other interest in any item of
Tenant’s Property. Landlord, however, by written notice to Tenant at least thirty (30) days prior to the Termination Date, may require Tenant, at its expense, to remove (a) any Cable installed by or for the benefit of Tenant, and
(b) any Tenant Additions that Landlord designated for removal at the time of consent and that, in Landlord’s reasonable judgment, are of a nature that would require removal and repair costs that are materially in excess of the removal and
repair costs associated with standard laboratory and office improvements (collectively referred to as “Required Removables”). Required Removables may include, without limitation, internal stairways, raised floors, personal baths and
showers, vaults, rolling file systems and structural alterations and modifications. The designated Required Removables shall be removed by Tenant before the Termination Date. Tenant’s removal and disposal of items pursuant to this
Section 12.1 must comply with the Project’s Sustainability Practices and Tenant is strongly encouraged to comply with the applicable Green Building Standards. Tenant shall repair damage caused by the installation or removal of Required
Removables. If Tenant fails to perform its obligations in a timely manner, Landlord may perform such work at Tenant’s expense. In the event possession of the Premises is not delivered to Landlord when required hereunder, or if Tenant shall fail
to remove those items described above, Landlord may (but shall not be obligated to), at Tenant’s expense, remove any of such property and store, sell or otherwise deal with such property, and undertake, at Tenant’s expense, such
restoration work as Landlord deems necessary or advisable. Notwithstanding anything in this Section 12.1 to the contrary, failure by Tenant to strictly comply with the provisions of this Section 12.1 with respect to any Required Removables
that are required to be removed from the Premises by Tenant hereunder shall constitute a failure of Tenant to validly surrender the Premises. 
 12.2
LANDLORD’S RIGHTS 
 All property which may be removed from the Premises by Landlord shall be conclusively presumed to have been
abandoned by Tenant and Landlord may deal with such property as provided in Section 11.2(b), including the waiver and indemnity obligations provided in that Section. Tenant shall also reimburse Landlord for all costs and expenses incurred by
Landlord in removing any Tenant Additions and in restoring the Premises to the condition required by this Lease. 
 ARTICLE 13 

HOLDING OVER 
 In the event
that Tenant holds over in possession of the Premises after the Termination Date, for each month or partial month Tenant holds over possession of the Premises, Tenant shall pay Landlord (i) 150% of the monthly Rent payable for the month
immediately preceding the holding over (including increases for Rent Adjustments which Landlord may reasonably estimate) for the first 90 days of such holdover and (ii) 200% of the monthly Rent payable for the month immediately preceding the
holding over (including increases for Rent Adjustments which Landlord may reasonably estimate) after the first 90 days of such holdover. Tenant shall also pay all damages, excluding, however, consequential damages (i.e., loss of income from
prospective tenants), sustained by Landlord by reason of such holding over. The provisions of this Article shall not constitute a waiver by Landlord of any re-entry rights of Landlord, and Tenant’s continued occupancy of the Premises shall be
as a tenancy in sufferance.

 ARTICLE 14 

DAMAGE BY FIRE OR OTHER CASUALTY 
 14.1
SUBSTANTIAL UNTENANTABILITY 
 (a) If any fire or other casualty (whether insured or uninsured) renders all or a substantial portion
of the Premises or the Building untenantable, Landlord shall, with reasonable promptness after the occurrence of such damage, estimate the length of time that will be required to substantially complete the repair and restoration and shall, by notice
advise Tenant of such estimate (“Landlord’s Notice”). If Landlord estimates that the amount of time required to substantially complete such repair and restoration will exceed two hundred seventy (270) days from the date such
damage occurred, then Landlord, or Tenant if all or a substantial portion of the Premises is rendered untenantable, shall have the right to terminate this Lease as of the date of such damage by delivering written notice to the other at any time
within twenty (20) days after delivery of Landlord’s Notice, provided that if Landlord so chooses, Landlord’s Notice may also constitute such notice of termination. 

(b) Unless this Lease is terminated as provided in the preceding subparagraph, Landlord shall proceed with reasonable promptness to repair and
restore the Premises to its condition as existed prior to such casualty, subject to reasonable delays for insurance adjustments and Force Majeure delays, and also subject to zoning Laws and building codes then in effect. Landlord shall have no
liability to Tenant, and Tenant shall not be entitled to terminate this Lease if such repairs and restoration are not in fact completed within the time period estimated by Landlord so long as Landlord shall proceed with reasonable diligence to
complete such repairs and restoration. 
 (c) Tenant acknowledges that Landlord shall be entitled to the full proceeds of any insurance
coverage, whether carried by Landlord or Tenant, for damages to the Premises, except for those proceeds of Tenant’s insurance for its own personal property and equipment which would be removable by Tenant at the Termination Date. All such
insurance proceeds shall be payable to Landlord whether or not the Premises are to be repaired and restored; provided, however, if this Lease is not terminated and the parties proceed to repair and restore Tenant Additions at Tenant’s cost, to
the extent Landlord received proceeds of Tenant’s insurance covering Tenant Additions, such proceeds shall be applied to reimburse Tenant for its cost of repairing and restoring Tenant Additions. 

(d) Notwithstanding anything to the contrary herein set forth: (i) Landlord shall have no duty pursuant to this Section to repair or
restore any portion of any Tenant Additions or to expend for any repair or restoration of the Premises or Building in amounts in excess of insurance proceeds paid to Landlord and available for repair or restoration; and (ii) Tenant shall not
have the right to terminate this Lease pursuant to this Section if any damage or destruction was caused by the willful misconduct or gross negligence of Tenant, its agent or employees. Whether or not this Lease is terminated pursuant to this Article
14, in no event shall Tenant be entitled to any compensation or damages for loss of the use of the whole or any part of the Premises or for any inconvenience or annoyance occasioned by any such damage, destruction, rebuilding or restoration of the
Premises or the Building or access thereto. 
 (e) Any repair or restoration of the Premises performed by Tenant shall be in accordance with
the provisions of Article 9 hereof. 
 14.2 INSUBSTANTIAL UNTENANTABILITY 

If the Premises or the Building is damaged by a casualty but neither is rendered substantially untenantable and either (i) Landlord
estimates that the time to substantially complete the repair or restoration will not exceed two hundred seventy (270) days from the date such damage occurred, or (ii) the cost to repair or restore is less than ten percent (I 0%) of the
replacement cost of the Building, then Landlord shall proceed to repair and restore the Building or the Premises other than Tenant Additions, with reasonable promptness, unless such damage is to the Premises and occurs during the last six
(6) months of the Term, in which event either Tenant or Landlord shall have the right to terminate this Lease as of the date of such casualty by giving written notice thereof to the other within twenty (20) days after the date of such
casualty. Notwithstanding the aforesaid, Landlord’s obligation to repair shall be limited in accordance with the provisions of Section 14.1 above. 

  
 - 44 - 













 14.3 RENT ABATEMENT 

Except if due to the willful misconduct of Tenant or its employees, if all or any part of the Premises are rendered untenantable by fire or
other casualty and this Lease is not terminated, Monthly Base Rent and Rent Adjustments shall abate for that part of the Premises which is untenantable on a per diem basis from the date of the casualty until Landlord has Substantially Completed the
repair and restoration work in the Premises which it is required to perform, provided, that as a result of such casualty, Tenant does not occupy the portion of the Premises which is untenantable during such period. 

14.4 WAIVER OF STATUTORY REMEDIES 
 The
provisions of this Lease, including this Article 14, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, the Premises or the Property or any part of either, and any Law, including
Sections 1932(2), 1933(4), 1941 and 1942 of the California Civil Code, with respect to any rights or obligations concerning damage or destruction shall have no application to this Lease or to any damage to or destruction of all or any part of the
Premises or the Property or any part of either, and are hereby waived. 
 ARTICLE 15 

EMINENT DOMAIN 
 15.1 TAKING OF WHOLE OR
SUBSTANTIAL PART 
 In the event the whole or any substantial part of the Building or of the Premises is taken or condemned by any
competent authority for any public use or purpose (including a deed given in lieu of condemnation) and is thereby rendered untenantable, this Lease shall terminate as of the date title vests in such authority, and Monthly Base Rent and Rent
Adjustments shall be apportioned as of the Termination Date. Notwithstanding anything to the contrary herein set forth, in the event the taking is temporary (for less than the remaining Term of this Lease), Landlord may elect either (i) to
terminate this Lease or (ii) permit Tenant to receive the entire award attributable to the Premises in which case Tenant shall continue to pay Rent and this Lease shall not terminate. 

15.2 TAKING OF PART 
 In the event a part
of the Building or the Premises is taken or condemned by any competent authority (or a deed is delivered in lieu of condemnation) and this Lease is not terminated, this Lease shall be amended to reduce or increase, as the case may be, the Monthly
Base Rent and Tenant’s Share to reflect the Rentable Area of the Premises or Building, as the case may be, remaining after any such taking or condemnation. Landlord, upon receipt and to the extent of the award in condemnation (or proceeds of
sale) shall make necessary repairs and restorations to the Premises (exclusive of Tenant Additions) and to the Building to the extent necessary to constitute the portion of the Building not so taken or condemned as a complete architectural and
economically efficient unit. Notwithstanding the foregoing, if as a result of any taking, or a governmental order that the grade of any street or alley adjacent to the Building is to be changed and such taking or change of grade makes it necessary
or desirable to substantially remodel or restore the Building or prevents the economical operation of the Building, Landlord shall have the right to terminate this Lease upon ninety (90) days prior written notice to Tenant. 

15.3 COMPENSATION 
 Landlord shall be
entitled to receive the entire award (or sale proceeds) from any such taking, condemnation or sale without any payment to Tenant, and Tenant hereby assigns to Landlord, Tenant’s interest, if any, in such award; provided, however, Tenant shall
have the right separately to pursue against the condemning authority a separate award in respect of the loss, if any, to Tenant Additions paid for by Tenant without any credit or allowance from Landlord.

 ARTICLE 16 

INSURANCE 
 16.1 TENANT’S
INSURANCE

the Term: (a) Commercial General Liability Insurance on a primary basis and without any right of contribution from any insurance carried by Landlord covering the Premises on an occurrence basis against all claims for personal injury, bodily
injury, death and property damage, including contractual liability covering the indemnification provisions in this Lease, and such insurance shall be for such limits that are reasonably required by Landlord from time to time but not less than a
combined single limit (each occurrence and in the aggregate) of Five Million Dollars ($5,000,000.00) (which limit may be achieved through use of umbrella coverage); (b) Workers’ Compensation and Employers’ Liability Insurance to the
extent required by and in accordance with the Laws of the State of California; (c) “All Risks” or “Special Form” property insurance in an amount adequate to cover the full replacement cost of all Tenant Additions, equipment,

16.2 FORM OF POLICIES 
 Each policy
referred to in Section 16.1 shall satisfy the following requirements. Each policy shall (i) name Landlord and the Indemnitees as additional insureds (except “All Risks” or “Special Form” property insurance, on which
Landlord and the Mortgagee, as their interests may appear, shall be named as “loss payees”, and Workers’ Compensation and Employers’ Liability insurance), (ii) be issued by one or more responsible insurance companies
licensed to do business in the State of California reasonably satisfactory to Landlord, (iii) where applicable, provide for deductible amounts satisfactory to Landlord and not permit co-insurance, and (iv) each policy of
“All-Risks” or “Special Form” property insurance shall provide that the policy shall not be invalidated should the insured waive in writing prior to a loss, any or all rights of recovery against any other party for losses covered
by such policy. Tenant shall deliver to Landlord certificate(s) of insurance prior to the Commencement Date and prior to the expiration date of each policy. Additionally, Tenant shall provide Landlord written notice of any cancellation or amendment
of any such insurance within two (2) Business Days following Tenant’s knowledge of the same. If Tenant fails to carry the insurance required under this Article 16 or fails to provide certificate(s) of such insurance and when required
hereunder and the same constitutes a Default hereunder, Landlord may, but shall not be obligated to acquire such insurance on Tenant’s behalf or Tenant’s sole cost and expense. 

16.3 LANDLORD’S INSURANCE 
 Landlord
agrees to purchase and keep in full force and effect during the Term hereof, including any extensions or renewals thereof, insurance under policies issued by insurers of recognized responsibility, qualified to do business in the State of California
on the Building in amounts sufficient to cover 80% of the replacement cost thereof, or an amount sufficient to prevent Landlord from becoming a co-insurer under the terms of the applicable policies, insuring against fire and such other risks as may
be included in “All Risks” or “Special Form” coverage insurance reasonably available from time to time (which requirement may be achieved through use of a single insurance policy covering multiple buildings owned by Landlord and
affiliates of Landlord). Landlord agrees to maintain in force during the Term, Commercial General Liability Insurance covering the Building on an occurrence basis against all claims for personal injury, bodily injury, death, and property damage.
Such insurance shall be for a combined single limit (each occurrence and in the aggregate) of not less than Five Million Dollars ($5,000,000.00) (which limit may be achieved through use of umbrella coverage). Neither Landlord’s obligation to
carry such insurance nor the carrying of such insurance shall be deemed to be an indemnity by Landlord with respect to any claim, liability, loss, cost or expense due, in whole or in part, to Tenant’s negligent acts or omissions or willful
misconduct. Without obligation to do so, Landlord may, in its sole discretion from time to time, carry insurance in amounts greater and/or for coverage additional to the coverage and amounts set forth above. Each policy of “All-Risks” or
“Special Form” property insurance required to be maintained by Landlord shall provide that the policy shall not be invalidated should the insured waive in writing prior to a loss, any or all rights of recovery against any other party for
losses covered by such policy. 

  
 - 46 - 













 16.4 WAIVER OF SUBROGATION AND CLAIMS 

(a) Landlord agrees that, if obtainable at no, or minimal, additional cost, and so long as the same is permitted under the laws of the State of
California, it will include in its “All Risks” or “Special Form” insurance policy or policies appropriate clauses pursuant to which the insurance companies (i) waive all right of subrogation against Tenant with respect to
losses payable under such policies and/or (ii) agree that such policies shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for losses covered by such policies. 

(b) Tenant agrees to include, if obtainable at no, or minimal, additional cost, and so long as the same is permitted under the laws of the
State of California, in its “All Risks” or “Special Form” insurance policy or policies on Tenant Additions, whether or not removable, and on Tenant’s furniture, furnishings, fixtures and other property removable by Tenant
under the provisions of this Lease, appropriate clauses pursuant to which the insurance company or companies (i) waive the right of subrogation against Landlord and/or any tenant of space in the Building with respect to losses payable under
such policy or policies and/or (ii) agree that such policy or policies shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for losses covered by such policy or policies. If
Tenant is unable to obtain in such policy or policies either of the clauses described in the preceding sentence, Tenant shall, if legally possible and without necessitating a change in insurance carriers, have Landlord named in such policy or
policies as an additional insured. If Landlord shall be named as an additional insured in accordance with the foregoing, Landlord agrees to endorse promptly to the order of Tenant, without recourse, any check, draft, or order for the payment of
money representing the proceeds of any such policy or representing any other payment growing out of or connected with said policies, and Landlord does hereby irrevocably waive any and all rights in and to such proceeds and payments. 

(c) (c) Landlord hereby waives any and all right of recovery which it might otherwise have against Tenant, its servants, agents and
employees, for loss or damage occurring to the Property and the fixtures, appurtenances and equipment therein, to the extent the same is coverable by Landlord’s insurance, notwithstanding that such loss or damage may result from the negligence
or fault of Tenant, its servants, agents or employees. Tenant hereby waives any and all right of recovery which it might otherwise have against Landlord, its servants, and employees and against every other tenant of the Real Property who shall have
executed a similar waiver as set forth in this Section 16.4(c) for loss or damage to Tenant Additions, whether or not removable, and to Tenant’s furniture, furnishings, fixtures and other property removable by Tenant under the provisions
hereof, to the extent the same is coverable by Tenant’s insurance required under this Lease, notwithstanding that such loss or damage may result from the negligence or fault of Landlord, its servants, agents or employees, or such other tenant
and the servants, agents or employees thereof. 
 (d) Landlord and Tenant hereby agree to advise the other promptly if the clauses to be
included in their respective insurance policies pursuant to subparagraphs (a) and (b) above cannot be obtained on the terms hereinbefore provided. Landlord and Tenant hereby also agree to notify the other promptly of any cancellation or
change of the terms of any such policy that would affect such clauses.

appurtenance therein, or resulting from any accident in or about the Premises or the Property, or resulting directly or indirectly from any act or neglect of any tenant or occupant of the Property or of any other person, including Landlord’s

Tenant hereby waives any consequential damages, compensation or claims for inconvenience or loss of business, rents, or profits as a result of such injury or damage, whether or not caused by the negligence or willful and wrongful act of any of the
Indemnitees. If any such damage, whether to the Premises or the Property or any part of either, or whether to Landlord or to other tenants in the Property, results from any act or neglect of Tenant, its employees, servants, agents, contractors,
invitees or customers, Tenant shall be liable therefor and Landlord may, at Landlord’s option, repair such damage and Tenant shall, upon demand by Landlord, as payment of additional Rent hereunder, reimburse Landlord within ten (I 0) days after
demand for the total cost of such repairs, in excess of amounts, if any, paid to Landlord under insurance covering such damages and except to the extent Landlord and its insurer have waived claims therefor pursuant to Section 16.4 above. Tenant
shall not be liable for any such damage caused by its acts or neglect if Landlord or a tenant has recovered the full amount of the damage from proceeds of insurance policies and the insurance company has waived its right of subrogation against
Tenant. 
 17.2 INDEMNITY 
 To the extent
permitted by Law, Tenant hereby indemnifies, and agrees to protect, defend and hold the Indemnitees harmless, against any and all actions, claims, demands, liability, costs and expenses, including attorneys’ fees and expenses for the defense

in the performance of any covenant or agreement on the part of Tenant to be performed pursuant to the terms of this Lease, or from any willful act or negligence of Tenant, its agents, contractors, servants, employees, customers or invitees, in or
about the Premises or the Property or any part of either. In case of any action or proceeding brought against the Indemnitees by reason of any such claim, upon notice from Landlord, Tenant covenants to defend such action or proceeding by counsel
chosen by Landlord, in Landlord’s sole discretion. Landlord reserves the right to settle, compromise or dispose of any and all actions, claims and demands related to the foregoing indemnity. The foregoing indemnity shall not operate to relieve
Indemnitees of liability to the extent such liability is caused by the sole negligence or willful and wrongful act of Indemnitees. Further, the foregoing indemnity is subject to and shall not diminish any waivers in effect in accordance with
Section 16.4 by Landlord or its insurers to the extent of amounts, if any, paid to Landlord under its “All Risks” property insurance. This Article 17 shall survive the expiration or earlier termination of this Lease.

provides or elects that this Lease shall be superior to such lease or mortgage or trust deed. If any such mortgage or trust deed is foreclosed (including any sale of the Real Property pursuant to a power of sale), or if any such lease is terminated,
upon request of the Mortgagee or ground lessor, as the case may be, Tenant shall attorn to the purchaser at the foreclosure sale or to the ground lessor under such lease, as the case may be, provided, however, that such purchaser or ground lessor
shall not be (i) bound by any payment of Rent for more than one (I) month in advance except payments in the nature of security for the performance by Tenant of its obligations under this Lease; (ii) subject to any offset, defense or
damages arising out of a default of any obligations of any preceding Landlord; or (iii) bound by any amendment or modification of this Lease made without the written consent of the Mortgagee or ground lessor; or (iv) liable for any
security deposits not actually received in cash by such purchaser or ground lessor. Notwithstanding the foregoing, Landlord agrees that upon written request from Tenant, Landlord shall request that any future Mortgagee provide a nondisturbance
agreement to Tenant on such Mortgagee’s standard form. In confirmation of such subordination, however, Tenant shall execute promptly any reasonable certificate or instrument that Landlord, Mortgagee or ground lessor may request. Tenant hereby
constitutes Landlord as Tenant’s attorney-in-fact to execute such certificate or instrument for and on behalf of Tenant upon Tenant’s failure to do so within fifteen (15) days after a request to do so. Upon request by such successor
in interest, Tenant shall execute and deliver reasonable instruments confirming the attornment provided for herein. The terms of this paragraph shall survive any termination of this Lease by reason of foreclosure. 

23.2 MORTGAGEE PROTECTION 
 Tenant agrees
to give any Mortgagee or ground lessor, by registered or certified mail, a copy of any notice of default served upon Landlord by Tenant, provided that prior to such notice Tenant has received notice (by way of service on Tenant of a copy of an
assignment of rents and leases, or otherwise) of the address of such Mortgagee or ground lessor. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease, then the Mortgagee or ground
lessor shall have an additional thirty (30) days after receipt of notice thereof within which to cure such default or if such default cannot be cured within that time, then such additional notice time as may be necessary, if, within such thirty
(30) days, any Mortgagee or ground lessor has commenced and is diligently pursuing the remedies necessary to cure such default (including commencement of foreclosure proceedings or other proceedings to acquire possession of the Real Property,
if necessary to effect such cure). Such period of time shall be extended by any period within which such Mortgagee or ground lessor is prevented from commencing or pursuing such foreclosure proceedings or other proceedings to acquire possession of
the Real Property by reason of Landlord’s bankruptcy. Until the time allowed as aforesaid for Mortgagee or ground lessor to cure such defaults has expired without cure, Tenant shall have no right to, and shall not, terminate this Lease on
account of default. This Lease may not be modified or amended so as to reduce the Rent or shorten the Term, or so as to adversely affect in any other respect to any material extent the rights of Landlord, nor shall this Lease be canceled or
surrendered, without the prior written consent, in each instance, of the ground lessor or the Mortgagee. Landlord shall make commercially reasonable efforts to obtain from Landlord’s current Mortgagee a form of non-disturbance agreement in
favor of Tenant on Mortgagee’s standard form, provided that Tenant shall pay any costs associated with obtaining such agreement (which costs shall not exceed Three Thousand Dollars ($3,000.00)) and in no event shall obtaining such agreement be
a condition to Tenant’s execution of or obligations under this Lease.

 ARTICLE 24 

NOTICES 
 (a) All notices,
demands or requests provided for or permitted to be given pursuant to this Lease must be in writing and shall be personally delivered, sent by FedEx or other reputable overnight courier service, or mailed by first class, registered or certified
United States mail, return receipt requested, postage prepaid. 
 (b) All notices, demands or requests to be sent pursuant to this Lease
shall be deemed to have been properly given or served by delivering or sending the same in accordance with this Article 24, addressed to the parties hereto at their respective addresses listed in Section 1.1. 

(c) Notices, demands or requests sent by mail or overnight courier service as described above shall be effective upon deposit in the mail or
with such courier service. However, except with respect to a notice given under Code of Civil Procedure Section 1161 et seq., the time period in which a response to any such notice, demand or request must be given shall commence to run from
(i) in the case of delivery by mail, the date of receipt on the return receipt of the notice, demand or request by the addressee thereof, or (ii) in the case of delivery by Federal Express or other overnight courier service, the date of
acceptance of delivery by an employee, officer, director or partner of Landlord or Tenant. Rejection or other refusal to accept or the inability to deliver because of changed address of which no notice was given, as indicated by advice from Federal
Express or other overnight courier service or by mail return receipt, shall be deemed to be receipt of notice, demand or request sent. Notices may also be served by personal service upon any officer, director or partner of Landlord or Tenant, and
shall be effective upon such service. 
 (d) By giving to the other party at least thirty (30) days written notice thereof, either party
shall have the right from time to time during the term of this Lease to change their respective addresses for notices, statements, demands and requests, provided such new address shall be within the United States of America. 

ARTICLE 25 
 MISCELLANEOUS

 25.1 LATE CHARGES 
 (a) All
payments required hereunder (other than the Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits, which shall be due as hereinbefore provided) to Landlord shall be paid within ten (10) business days after Landlord’s written
invoice therefor together with reasonable back-up information substantiating the invoiced payments. All such amounts (including Monthly Base Rent, Rent Adjustments, and Rent Adjustment Deposits) not paid when due shall bear interest from the date
due until the date paid at the Default Rate in effect on the date such payment was due. 
 (b) In the event Tenant is more than five
(5) days late in paying any installment of Rent due under this Lease, Tenant shall pay Landlord a late charge equal to five percent (5%) of the delinquent installment of Rent, provided, however, that Landlord agrees to waive the first such
late charge in each calendar year during the Tenn. The parties agree that (i) such delinquency will cause Landlord to incur costs and expenses not contemplated herein, the exact amount of which will be difficult to calculate, including the cost
and expense that will be incurred by Landlord in processing each delinquent payment of rent by Tenant, (ii) the amount of such late charge represents a reasonable estimate of such costs and expenses and that such late charge shall be paid to
Landlord for each delinquent payment in addition to all Rent otherwise due hereunder. The parties further agree that the payment of late charges and the payment of interest provided for in subparagraph (a) above are distinct and separate from
one another in that the payment of interest is to compensate Landlord for its inability to use the money improperly withheld by Tenant, while the payment of late charges is to compensate Landlord for its additional administrative expenses in
handling and processing delinquent payments. 
 (c) Payment of interest at the Default Rate and/or of late charges shall not excuse or cure
any default by Tenant under this Lease, nor shall the foregoing provisions of this Article or any such payments prevent Landlord from exercising any right or remedy available to Landlord upon Tenant’s failure to pay Rent when due, including the
right to terminate this Lease.

 25.2 NO JURY TRIAL; VENUE; JURISDICTION 

To the fullest extent permitted by Laws, each party hereto (which includes any assignee, successor, heir or personal representative of a party)

any action or proceeding or counterclaim brought by any party hereto against the other on any matter whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, Tenant’s use or occupancy of the
Premises, or any claim of injury or damage, or the enforcement of any remedy under any statute, emergency or otherwise, whether any of the foregoing is based on this Lease or on tort law. No party will seek to consolidate any such action in which a
jury has been waived with any other action in which a jury trial cannot or has not been waived. It is the intention of the parties that these provisions shall be subject to no exceptions. The provisions of this Section shall survive the expiration
or earlier termination of this Lease. 
 25.3 NO DISCRIMINATION 

Tenant agrees for Tenant and Tenant’s heirs, executors, administrators, successors and assigns and all persons claiming under or through
Tenant, and this Lease is made and accepted upon and subject to the following conditions: that there shall be no discrimination against or segregation of any person or group of persons on account of race, color, creed, religion, sex, marital status,

practices of discrimination or segregation with reference to the use or occupancy of the Premises by Tenant or any person claiming through or under Tenant.

connection with the administration of this Lease. 
 25.5 OPTION 

This Lease shall not become effective as a lease or otherwise until executed and delivered by both Landlord and Tenant. The submission of this
Lease to Tenant does not constitute a reservation of or option for the Premises, but when executed by Tenant and delivered to Landlord, this Lease shall constitute an irrevocable offer by Tenant in effect for fifteen (15) days to lease the

possession of the Premises shall reinstate, continue or extend the Term. Receipt or acceptance of payment from anyone other than Tenant, including an assignee of Tenant, is not a waiver of any breach of Article 10, and Landlord may accept such
payment on account of the amount due without prejudice to Landlord’s right to pursue any remedies available to Landlord. 
 25.11 LANDLORD’S
OBLIGATIONS ON SALE OF BUILDING

Specialist. Furthermore, pursuant to Section 1938 of the California Civil Code, Landlord notifies Tenant of the following: “A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises
comply with all of the applicable construction-related accessibility standards under state law. Although California state law does not require a CASp inspection of the subject premises, the commercial property owner or lessor may not prohibit the
lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and
manner of any such CASp inspection, the payment of the costs and fees for the CASp inspection and the cost of making any repairs necessary to correct violations of construction- related accessibility standards
within the Premises.” Tenant agrees that (a) Tenant may, at its option and at its sole cost, cause a CASp to inspect the Premises and determine whether the Premises complies with all of the applicable construction-related accessibility
standards under California law, (b) the parties shall mutually coordinate and reasonably approve of the timing of any such CASp inspection so that Landlord may, at its option, have a representative present during such inspection, and

alterations and repairs within the Premises to be performed by Tenant shall be subject to Landlord’s consent and in accordance with this Lease. Landlord and Tenant hereby agree that if Tenant elects to perform a CASp inspection of the Premises,
Tenant will provide written notice to Landlord, and Landlord may elect, in Landlord’s sole discretion, lo retain a CASp to perform the inspection. If Landlord does not so elect, the time and manner of the CASp inspection is subject to the prior
written approval of Landlord. In either event, the payment of the fee for the CASp inspection shall be borne by Tenant.

THIS WORK AGREEMENT (this “Work Agreement”) is attached to and made a part of that certain Lease (the “Lease”) between

pursuant to this Work Agreement in a total amount which exceeds the Suite 120 Tenant Improvement Allowance. Tenant must complete all Tenant Work and have submitted Payment Request Supporting Documentation (defined below) for such work, in each case
subject to day for day extension due to Force Majeure, no later than November 30, 2022, in order to be entitled to receive the Suite 120 Tenant Improvement Allowance for such work.

Parties (defined below) who have lien rights with respect to the subject request for payment (along with unconditional mechanics’ lien releases with respect to payments made pursuant to Tenant’s prior submission hereunder) in compliance

the Approved Working Drawings (defined below) or due to any substandard work and delivers a written objection to such item setting forth with reasonable particularity Landlord’s reasons for its dispute (a “Draw Dispute Notice”) within
ten (I 0) Business Days following Tenant’s submission of its Payment Request Supporting Documentation, Landlord may deduct the amount of such disputed item from the payment. Landlord and Tenant shall, in good faith, endeavor to diligently
resolve any such dispute. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s payment request. 

(C) Subject to the provisions of this Work Agreement, following the final completion of construction of the Tenant Work, Landlord shall

to prepare all plans and engineering working drawings and perform all work relating to mechanical, electrical and plumbing (“MEP”), HVAC/Air Balancing, life-safety, structural, sprinkler and riser work. 

(ii) The plans and drawings to be prepared by Architect and the Building Consultants hereunder (i.e., both the Space Plan and the Working

be subject to Landlord’s prior written 

  
 - 63 - 













 
approval, not to be unreasonably withheld, conditioned or delayed. All MEP drawings must be fully engineered or prepared on a “design-build-assist” basis with a Landlord-approved MEP
basis of design (“BOD”), as prepared by an approved MEP engineer consultant. The MEP drawings cannot be prepared on a strictly “design-build” basis. Landlord’s review of the Construction Drawings shall be for its sole
purpose and shall not obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly, notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers
and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith
and shall not be responsible for any omissions or errors contained in the Construction Drawings. 
 (b) Space Plan. Tenant shall
supply Landlord for Landlord’s review and approval with a copy (which may be in electronic form) of its space plan for Suite 120 (“Space Plan”) before any architectural working drawings or engineering drawings have been commenced. The
Space Plan shall include a layout and designation of all laboratory facilities, offices, rooms and other partitioning, their intended use, and equipment to be contained therein. Landlord may request clarification or more specific drawings for
special use items not included in the Space Plan. Landlord shall advise Tenant within ten (10) Business Days after Landlord’s receipt of the Space Plan (or, if applicable, such additional information requested by Landlord pursuant to the
provisions of the immediately preceding sentence) if the same is approved or is unsatisfactory or incomplete in any respect. Upon any disapproval by Landlord, Tenant shall promptly cause the Space Plan to be revised to correct any deficiencies or
other matters Landlord may reasonably require.
