THIS LEASE, referred to herein as this “Lease,” is made and entered into as of August 14, 2019, by and between MENLO
PREPI I, LLC, a Delaware limited liability company, and TPI INVESTORS 9, LLC, a California limited liability company, hereafter collectively referred to as “Landlord,” and ZAI LAB (US) LLC, a Delaware limited
liability company, hereafter referred to as “Tenant.” 
 RECITALS 

A. Landlord is the owner of the real property located in Menlo Business Park, Menlo Park, California, commonly referred to as 1430 and 1440
O’Brien Drive, more particularly described on Exhibit “A” attached hereto and incorporated by reference herein, together with all easements and appurtenances thereto (collectively, the “Land”) and the existing
buildings thereon, containing approximately 83,029 rentable square feet and all other improvements located thereon (collectively, the “Improvements”). The Land and Improvements are referred to herein collectively as the
“Property.” The Menlo Business Park Master Plan is attached hereto as Exhibit “B” and incorporated by reference herein, and identifies the properties that comprise the Menlo Business Park. The buildings at 1430 and
1440 O’Brien Drive are referred to, together, herein as the “Building.” The floor plan of the Building is attached hereto as Exhibit “C” and incorporated by reference herein. 

B. Landlord and Tenant wish to enter into this Lease of the Premises defined in Paragraph 1 upon the terms and conditions set forth herein.

 NOW, THEREFORE, the parties agree as follows: 
  

	1.	 Lease. 



(a) Beginning on the Commencement Date (as defined in Paragraph 2(a)), Landlord hereby leases to Tenant, and Tenant leases from Landlord, at
the rental rate and upon the terms and conditions set forth herein, the portions of the Building commonly referred to as Suite A on the first floor and Suite C on the second floor of 1440 O’Brien Drive, Menlo Park, California, together with
Tenant’s non-exclusive right to use the common areas within the Building and the other Improvements on the Property intended for use in common by the tenants of the Building (the “Common
Area”), and consisting of approximately Eighteen Thousand Seven Hundred Seven (18,707) rentable square feet, as shown on the floor plan of the Building attached hereto as Exhibit “C” (the “Premises”),
together with the right to use Tenant’s share of the on-site parking spaces pursuant to Paragraph 27 hereof. Tenant’s Pro Rata Share of the Building shall mean 22.53% (18,707/83,029). 











 (b) Except hereinafter provided, Landlord shall retain absolute dominion and control over
the Common Area and shall operate and maintain the Common Area in good order and condition; provided, however, such exclusive right shall not materially adversely affect Tenant’s access to the Premises nor shall it operate to materially
adversely affect Tenant’s benefit and enjoyment of the Premises for Tenant’s Permitted Use. Notwithstanding anything to the contrary herein, Landlord grants Tenant, its employees, invitees, licensees, and other visitors a non-exclusive license to use the Common Area for the Term hereof (as may be extended). Tenant acknowledges that, without advance notice to Tenant, and without any liability to Tenant in any respect so long as
Tenant’s access to nor its Permitted Use is not materially adversely affected, Landlord shall have the right to: 
 (i) Close off any of
the Common Area to whatever extent required, in the opinion of Landlord, to prevent a dedication of any of the Common Area or the accrual of any rights by any person or the public to the Common Area, provided such closure does not materially deprive
Tenant of the benefit and enjoyment of the Premises for its Permitted Use; 
 (ii) Temporarily close any of the Common Area for maintenance,
alteration or improvement purposes; 
 (iii) Select, appoint or contract with any person for the purpose of operating and maintaining the
Common Area, on such terms and conditions as Landlord deems reasonable; 
 (iv) Change the size, use, shape or nature of any such Common
Area, provided such change does not materially adversely affect Tenant’s benefit and enjoyment of the Premises, and access to the Premises is not materially adversely affected. So long as Tenant’s benefit and enjoyment of the Premises is
not materially adversely affected or access to the Premises is not materially adversely affected, Landlord will also have the right at any time to change the arrangement or location, or both, or to regulate or eliminate the use of any concourse, or
any elevator, stairs, toilet or other public conveniences in the Building and/or Property, without incurring any liability to Tenant or entitling Tenant to any abatement of Rent; 

(v) Expand the existing Building and/or any other buildings within the Property to cover a portion of the Common Area, convert the Common Area
to a portion of the Building or other buildings within the Property, or convert any portion of the Building (excluding the Premises) or any other buildings within the Property to Common Area, Tenant’s proportionate share shall not increase
(except to a de minimis extent). Upon erection of any buildings or expansion of the Building, or change in Common Area, the portion of the Building or other buildings upon which such structures have been erected will no longer be deemed to be a part
of the Common Area; and 
 (vi) In addition to the other rights of Landlord under this Lease, Landlord reserves to itself and its respective
successors and assigns the right to: (i) change the street address and/or name of the Building and/or Property; (ii) erect, use and maintain pipes and conduits in and through the Premises; provided that such pipes and conduits shall not be
visible from the interior of the Premises and in no event shall the usable area of the Premises be diminished by other than a de minimis amount nor shall Tenant’s use and enjoyment of the Premises be materially adversely affected;
(iii) grant to anyone the exclusive right to conduct any particular business or undertaking in the Property provided that Tenant shall not be bound thereby; (iv) grant to anyone the exclusive use of portions of any storage areas to
tenants; (v) control the use of the roof and exterior walls of the Building and/or other buildings in the Property; (vi) change the boundary lines of the lot on which the Building stands and/or Property is located and to make other
reasonable changes therein and grant other rights thereto, including, without limitation, the granting of easements, servitudes, rights of way and rights of ingress and egress and similar rights to users of adjacent parcels, utility companies,
governmental agencies or other tenants so long as Tenant’s access to the Property and Building is not materially changed; and (vii) make alterations, repairs or replacements within other premises within the Building or Property. Landlord
may exercise any or all of the foregoing rights without being deemed to be guilty of an eviction or disturbance or interruption of the business of Tenant or Tenant’s use or occupancy of the Premises. 

  
 2 












 (vii) Notwithstanding the foregoing or anything to the contrary herein, in the event that
Landlord reduces the square footage of the Common Area, this Lease shall be amended to reflect such reduced square footage, and Tenant’s pro rata share of the operating expenses of Menlo Business Park shall be adjusted accordingly. 

 

	2.	 Term. 



(a) The term of this Lease (the “Term”) shall commence on the earlier of: (i) the date that Landlord delivers the
Premises to Tenant with the Tenant Improvements Substantially Completed (as defined in the Work Letter attached hereto as Exhibit “G”), and (ii) the date such work would have been Substantially Completed but for the occurrence
of Tenant Delays (as defined in the Work Letter) (the “Commencement Date”). Landlord shall permit Tenant to have access to the Premises during normal business hours fourteen (14) days prior to Substantial Completion of the
Tenant Improvements for the purpose of installing Tenant’s wiring and cabling; provided that such access shall not interfere with Landlord’s Substantial Completion of the Landlord’s Work and Tenant Improvements (as defined in the
“Work Letter”). If Tenant’s early access interferes with Landlord’s Substantial Completion of the Landlord’s Work or Tenant Improvements, Landlord may, in its reasonable discretion, terminate Tenant’s early access by
twenty-four (24) hours’ written notice to Tenant; provided, however, Landlord and Tenant shall reasonably cooperate to minimize interference with each party’s activities and ensure compliance with all rules, ordinances and regulations
of the City of Menlo Park concerning such early access period. Such early access shall be at no cost (neither Base Rent nor Operating Expenses), but shall be at Tenant’s sole risk and subject to all the other provisions of this Lease, including
without limitation prior delivery to Landlord of insurance certificates evidencing that Tenant has obtained the insurance required pursuant to this Lease. Tenant shall not install any furniture, fixtures or equipment in the Premises or conduct its
business in the Premises at any time during this early access period. In addition to the foregoing, Landlord shall have the right to impose such reasonable additional conditions on Tenant’s early access as Landlord shall deem appropriate. The
Commencement Date shall be confirmed in writing by Landlord and Tenant by the execution and delivery of the Commencement Memorandum in the form attached hereto as Exhibit “D”. 

(b) The Term of this Lease shall expire, unless sooner terminated in accordance with the provisions hereof or as permitted by law, on the last
day of the Seventy-Second (72nd) full calendar month after the Commencement Date (“Expiration Date”) unless extended in accordance with Paragraph 2(c) below. 

  
 3 












 (c) Extension Option. Tenant shall have one (1) option to extend the Term of this Lease
(“Extension Option”) for an additional period of sixty (60) months (“Extended Term”) by giving Landlord written notice of such election (“Option Exercise Notice”) not earlier than twelve
(12) months nor later than nine (9) months prior to the Expiration Date. If Tenant does not timely deliver the Option Exercise Notice, Tenant’s right to exercise the Extension Option shall terminate. Tenant shall have no right to
exercise the Extension Option notwithstanding any provision in the grant to the contrary if Tenant does not occupy at least fifty percent (50%) of the Premises or is in default of this Lease after any applicable notice and cure period. The Extension
Option is personal to the originally-named tenant or a Permitted Transferee and may not be exercised or assigned, voluntarily or involuntarily, by or to any person or entity or exercised for the occupancy of any other person or entity. The Extended
Term shall be on the same terms and conditions as contained in this Lease except that (i) there shall be no further right to extend the Lease beyond the Extended Term, (ii) there shall be no obligation to
pre-pay monthly base rent, initial rent concessions or abatements or obligation of Landlord to construct tenant improvements or pay a tenant improvement allowance, and (iii) Monthly Base Rent during the
Extended Term shall equal the Fair Market Rental Rate determined in accordance with this Paragraph. 
 As used herein, the term
“Fair Market Rental Rate” means the rental rate that Landlord could obtain during the Extended Term from a third party desiring to lease the Premises, based upon the Permitted Use, as determined by rents then being obtained
for renewal leases of space comparable in age, build-out and quality to the Premises in the locality of the Premises, taking into account any initial rent concessions, abatements and/or tenant improvement
allowances then being obtained for comparable space for renewal leases in the locality of the Premises. 
 If Tenant delivers the Option
Exercise Notice, Landlord shall, within thirty (30) days of receipt thereof, send Tenant a written notice setting forth the Fair Market Rental Rate for the Extended Term. If Tenant disputes Landlord’s determination, Tenant shall, within
thirty (30) days of Landlord’s notice setting forth Landlord’s determination of the Fair Market Rental Rate, send to Landlord a notice stating that Tenant disagrees with Landlord’s determination and elects to resolve the
disagreement as set forth herein. If Tenant does not send Landlord a notice as provided in the previous sentence, Landlord’s determination of Fair Market Rental Rate shall be the Monthly Base Rent payable by Tenant during the Extended Term. If
Tenant elects to resolve the disagreement as provided below and such procedures are not concluded prior to the commencement date of the Extended Term, Tenant shall pay to Landlord as Monthly Base Rent the Fair Market Rental Rate set forth in
Landlord’s notice. If the Fair Market Rental Rate as finally determined pursuant to the provisions set forth below is greater than Landlord’s determination, Tenant shall pay Landlord the difference between the amount paid by Tenant and the
Fair Market Rental Rate as so determined within thirty (30) days after said determination. If the Fair Market Rental Rate as finally determined is less than Landlord’s determination, the difference between the amount paid by Tenant and the
Fair Market Rental Rate as so determined shall be credited against the next installments of Monthly Base Rent due from Tenant to Landlord hereunder. 

Any disagreement regarding the Fair Market Rental Rate shall be resolved as follows: 

(i) If within thirty (30) days of Tenant’s notice of disagreement with Landlord’s determination of Fair Market Rental, Landlord
and Tenant cannot reach agreement as to Fair Market Rental, Landlord and Tenant shall each select one appraiser to determine the Fair Market Rental Rate. Each such appraiser shall arrive at a determination of the Fair Market Rental Rate and submit
their conclusions to Landlord and Tenant within sixty (60) days of Tenant’s notice of disagreement of Landlord’s determination of the Fair Market Rental Rate. 

  
 4 












 (ii) If only one appraisal is submitted within the requisite time period, it shall be deemed
as the Fair Market Rental Rate. If both appraisals are submitted within such time period and the two appraisals so submitted differ by less than ten percent (10%), the average of the two shall be deemed as the Fair Market Rental Rate. If the two
appraisals differ by more than ten percent (10%), the appraisers shall immediately select a third appraiser who shall, within fifteen (15) days after his/her selection, determine which of the two appraisals most closely represents the Fair
Market Rental Rate. 
 (iii) All appraisers specified pursuant to this Paragraph shall be either members of the American Institute of Real
Estate Appraisers or a licensed California Real Estate Broker with not less than ten (10) years’ experience appraising office properties in the immediate geographic area of the Building. Each party shall pay the cost of the appraiser
selected by such party and one-half of the cost of the third appraiser. The “immediate geographic area of the Building” shall mean the cities of Palo Alto and Menlo Park. 

 

	3.	 Monthly Base Rent. 



(a) Commencing on the Commencement Date and continuing on the first day of each calendar month thereafter until the end of the Term, Tenant
shall pay to Landlord in monthly installments in advance the Monthly Base Rent for the Premises in lawful money of the United States as follows:

Personal property taxes related to the Premises; any parking taxes or parking levies imposed on the Premises in the future by any governmental
agency; a management fee charged for the management and operation of Menlo Business Park, in an amount equal to four percent (4%) of the total gross income received by Landlord from the Tenant (including Monthly Base Rent and Additional Rent), and
not just Tenant’s Pro Rata Share of this fee; water and sewer charges; waste disposal; insurance premiums for insurance coverages maintained by Landlord pursuant to Paragraph 10(e) hereof; license, permit, and inspection fees; charges for

of Tenant’s specific use of the Property, if Landlord is required to or voluntarily incurs any capital expenses, Landlord shall amortize such expenses over the useful life of the capital repairs, replacements or improvements calculated in
accordance with generally accepted accounting principles (together with interest on the unamortized balance at the rate equal to the effective rate of interest on Landlord’s bank line of credit at the time of completion of said repairs,
replacements or improvements, but in no event in excess of ten percent (10%) per annum) as an Operating Expense in accordance with generally accepted accounting principles, except that with respect to capital improvements made to save Operating
Expenses such amortization shall not be at a rate greater than the actual savings in Operating Expenses. Operating Expenses shall also include any other expense or charge, whether or not described herein but which is not specifically excluded by
other provisions of this Lease, which in accordance with generally accepted accounting principles would be considered an expense of managing, operating, maintaining, and repairing the Property. 

  
 6 












 (c) Real property taxes and assessments upon the Property, during each lease year or partial
lease year during the Term of this Lease (as may be extended) are referred to herein as “Taxes.” 
 As used herein, Taxes shall
mean:

appears to Landlord that the Operating Expenses, Taxes or Park Expenses for such year will vary from Landlord’s estimate, Landlord may, by written notice to Tenant, revise Landlord’s estimate for such year and the Additional Rent payments
by Tenant for such year shall thereafter be based upon such revised estimate. Landlord shall furnish to Tenant with such revised estimate written verification showing that the actual Operating Expenses, Taxes or Park Expenses are greater than or
equal to Landlord’s estimate. The increase in the monthly installments of Additional Rent resulting from Landlord’s revised estimate shall not be retroactive, but the Additional Rent for each calendar year shall be subject to adjustment
between Landlord and Tenant after the close of the calendar year, as provided below. 

  
 9 












 Within approximately ninety (90) days after the expiration of each calendar year of the
Term (as may be extended), Landlord shall furnish Tenant a statement certified by a responsible employee or agent of Landlord (the “Operating Statement”) with respect to such year, prepared by an employee or agent of Landlord,
showing the actual Operating Expenses, Taxes and Park Expenses for such year broken down by component expenses, and the total payments made by Tenant for such year on the basis of any previous estimate of such Operating Expenses, Taxes and Park
Expenses, all in sufficient detail for verification by Tenant. Unless Tenant raises any objections to the Operating Statement within ninety (90) days after receipt of the same, such statement shall conclusively be deemed correct and Tenant
shall have no right thereafter to dispute such statement or any item therein or the computation of Operating Expenses and/or Taxes and/or Park Expenses. Upon giving Landlord five (5) days advance written notice, Tenant or its accountants shall
have the right to inspect and audit Landlord’s books and records with respect to the Operating Statement in an office of Landlord, or Landlord’s agent, during normal business hours, once each Lease Year to verify actual Operating Expenses
and/or Taxes and/or Park Expenses. Should Tenant retain any accountant or accounting firm to audit or inspect Landlord’s books and records pursuant to this Paragraph 4(e), such accountant or accounting firm shall be one of national standing and
retained on an hourly rate basis or based upon a fixed fee and shall not be paid on a contingency basis. Landlord’s books and records shall be kept in accord with generally accepted accounting principles. If Tenant’s audit of the Operating
Expenses and/or Taxes and/or Park Expenses for any year reveals a net overcharge of more than five percent (5%), Landlord shall promptly reimburse Tenant for the cost of the audit; otherwise, Tenant shall bear the cost of Tenant’s audit. If
Tenant reasonably objects to Landlord’s Operating Statement, Tenant shall nonetheless continue to pay on a monthly basis the Operating Expenses, Taxes and Park Expenses based upon the Landlord’s most current estimate until such dispute is
resolved. 
 If Tenant’s Pro Rata Share of the Operating Expenses and Taxes and Tenant’s pro rata share of Park Expenses for any
year as finally determined exceed the total payments made by Tenant for such year based on Landlord’s estimates, Tenant shall pay to Landlord the deficiency, within thirty (30) days after the receipt of Landlord’s Operating Statement.
If the total payments made by Tenant based on Landlord’s estimate of the Operating Expenses and/or Taxes and/or Park Expenses exceed the Tenant’s Pro Rata Share of Operating Expenses and/or Taxes and/or Tenant’s pro rata share of Park
Expenses, Tenant’s extra payment, plus the cost of an audit which is the responsibility of Landlord as set forth herein, if any, shall be credited against payments of Monthly Base Rent and Additional Rent next due hereunder or returned within
thirty (30) days if the Term (as may be extended) has expired or this Lease has been terminated. 

  
 10 












 Notwithstanding the expiration or termination of this Lease, within thirty (30) days
after Tenant’s receipt of Landlord’s Operating Statement or the completion of Tenant’s audit regarding the Operating Expenses and/or Taxes and/or Park Expenses for the calendar year in which this Lease terminates, Tenant shall pay to
Landlord or shall receive from Landlord, as the case may be, an amount equal to the difference between the Operating Expenses and/or Taxes and/or Park Expenses for such year, as finally determined, and the amount previously paid by Tenant on account
thereof (prorated to the expiration date or the termination date of this Lease). 
  

	5.	 Payment of Rent. 



(a) All rent shall be due and payable in lawful money of the United States of America at the address of Landlord provided herein and otherwise
in accordance with Paragraph 23, “Notices,” without deduction or offset and without prior demand or notice, unless otherwise specified herein. Monthly Base Rent and Additional Rent shall be payable monthly, in advance, on the first
day of each month. Additional Rent shall be payable monthly, in advance, on the first day of each month for the entire Premises for the entire Term of this Lease (as may be extended). Tenant’s obligation to pay rent for any partial month at the
commencement of the Term (as may be extended), for any partial month immediately prior to a rental adjustment date (if the rental adjustment date is other than the first day of the calendar month), and for any partial month at the expiration or
termination of the Term (as may be extended) shall be based upon the number of days in such month. 
 (b) If any installment of Monthly Base
Rent, Additional Rent or any other sum due from Tenant is not received by Landlord within five (5) days after the same is due, Tenant shall pay to Landlord an additional sum equal to five percent (5%) of the amount overdue as a late charge. The
parties agree that this late charge represents a fair and reasonable estimate of the costs that Landlord will incur by reason of the late payment by Tenant. Acceptance of any late charge shall not constitute a waiver of Tenant’s default with
respect to the overdue amount Any amount not paid within ten (10) days after Tenant’s receipt of written notice that such amount is due shall bear interest from the date due until paid at the lesser rate of (1) the prime rate of
interest as published in the “Wall Street Journal” plus two percent (2%) or (2) the maximum rate allowed by law (the “Interest Rate”), in addition to the late
payment charge.

 6. Security Deposit/ Letter of Credit. Tenant shall deposit with Landlord upon execution hereof the
sum of One Hundred Thirty-Five Thousand Eight Hundred Eighty-Eight and 80/100 Dollars ($135,888.80) (the “Security Deposit”), as security for Tenant’s faithful performance of Tenant’s obligations under this Lease, If
Tenant fails to pay Monthly Base Rent or Additional Rent or charges due hereunder within applicable notice and cure periods, or otherwise defaults under this Lease (as defined in Paragraph 21), Landlord may use, apply or retain all or any portion of
said Security Deposit to the extent reasonably necessary to cure the default, for the payment of any amount due Landlord, and to reimburse or compensate Landlord for any liability, cost, expense, loss or damage (including attorneys’ fees) which
Landlord may suffer or incur by reason thereof. If Landlord uses or applies all or any portion of the Security Deposit, Tenant shall within ten (10) days after written request therefor deposit with Landlord the amount sufficient to restore the
Security Deposit to the original amount required by this Lease. Landlord shall not be required to keep all or any part of the Security Deposit separate from its general accounts. In no event or circumstance shall Tenant have the right to any use of
the Security Deposit and, specifically, Tenant may not use the Security Deposit as a credit or to otherwise offset any payments required hereunder, including, but not limited to, rent or any portion thereof. Tenant waives (i) California Civil
Code Section 1950.7 and any and all other laws, rules and regulations applicable to security deposits in the commercial context (“Security Deposit Laws”), and (ii) any and all rights, duties and obligations either party
may now has, or in the future will have, relating to or arising from the Security Deposit Laws. Notwithstanding anything to the contrary herein, the Security Deposit may be retained and applied by Landlord (a) to offset rent which is unpaid
either before or after termination of this Lease, and (b) against other damages suffered by Landlord before or after termination of this Lease. No part of the Security Deposit shall be considered to be held in trust, to bear interest or other
increment for its use, or to be prepayment for any moneys to be paid by Tenant under this Lease. If Tenant fully and faithfully performs all of its obligations under this Lease, Landlord shall return the unused portion of the Security Deposit within
thirty (30) days following the expiration or earlier termination of this Lease and receipt of written closure reports from the San Mateo County Health Department and the Menlo Park Fire Protection District that provide written certification
that all Hazardous Materials have been removed from the Premises and that no further action is required in connection with the closure of the Premises as and to the extent required by Section 13(h) of this Lease. 

Tenant shall deliver to Landlord, within thirty (30) days following execution of this Lease, an unconditional, clean, irrevocable letter
of credit (the “L-C”) in the amount of Four Hundred Seventy Thousand Two Hundred Eighteen Dollars ($470,218.00) (the “L-C Amount”),
which L-C shall be issued by a money-center bank (a bank which accepts deposits, maintains accounts, has a local Silicon Valley and/or San Francisco office which will negotiate the L-C, and whose deposits are insured by the FDIC) acceptable to Landlord in its sole but reasonable discretion, and which L-C shall be in form and content as set forth on
Exhibit “H” attached hereto, or otherwise reasonably acceptable to Landlord. Tenant may, at its option, deposit with Landlord the amount of Four Hundred Seventy Thousand Two Hundred Eighteen Dollars ($470,218.00) in cash in lieu of
the L-C within thirty (30) days following execution of this Lease. Landlord hereby approves Silicon Valley Bank as the issuing bank for the L-C. Tenant shall pay
all expenses, points and/or fees incurred by Tenant in and maintaining the L-C. The L-C shall be held by Landlord as security for the faithful performance by Tenant of
all the terms, covenants, and conditions of this Lease to be kept and performed by Tenant during the Lease term (including renewals). The L-C shall not be mortgaged, assigned or encumbered in any manner
whatsoever by Tenant without the prior written consent of Landlord. If Tenant defaults with respect to any provisions of this Lease (following the expiration of all applicable cure periods without cure), including, but not limited to, the provisions
relating to the payment of rent, or if Tenant fails to renew the L-C at least thirty (30) days before its expiration, Landlord may, but shall not be required to, draw upon all or any portion of the L-C for payment of any rent or any other sum in default, or for the payment of any amount that Landlord may reasonably spend or may become obligated to spend by reason of Tenant’s default, or to compensate
Landlord for any other loss or damage that Landlord may suffer by reason of Tenant’s default. The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord
from exercising any other right or remedy provided by this Lease or by law, it being intended that Landlord shall not first be required to proceed against the L-C and shall not operate as a limitation on any
recovery to which Landlord may otherwise be entitled. Any amount of the L-C which is drawn upon by Landlord, but is not used or applied by Landlord, shall be held by Landlord and deemed a security deposit (the
“L-C Security Deposit”). If any portion of the L-C is drawn upon, Tenant shall, within three (3) business days after written demand therefor, either
(i) deposit cash with Landlord (which cash shall be applied by Landlord to the L-C Security Deposit) in an amount sufficient to cause the sum of the L-C Security
Deposit and the amount of the remaining L-C to be equivalent to the amount of the L-C then required under this Lease or (ii) reinstate the L- C to the amount then required under this Lease, and if any portion of the L-C Security Deposit is so used or applied, Tenant shall, within three (3) business days
after written demand therefor, deposit cash with Landlord (which cash shall be applied by Landlord to the L-C Security Deposit) in an amount sufficient to restore the
L-C Security Deposit to the amount then required under this Lease, and Tenant’s failure to do so shall be a default under this Lease. Tenant acknowledges that Landlord has the right to transfer or
mortgage its interest in the Building and in this Lease and Tenant agrees that in the event of any such transfer or mortgage, Landlord shall have the right to transfer or assign the L-C Security Deposit and/or
the L-C to the transferee or mortgagee, and in the event of such transfer, Tenant shall look solely to such transferee or mortgagee for the return of the L-C Security
Deposit and/or the L-C, provided that Landlord delivers commercially reasonable written evidence of such transfer to Tenant. Tenant shall, within ten (10) business days of request by Landlord, execute
such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm Landlord’s transfer or assignment of the L-C Security Deposit and/or the L-C to such transferee or mortgagee.

approved by Landlord in writing, (the “Permitted Use”), and for no other use or purpose without Landlord’s prior written consent; provided, that the use of the Premises for the manufacture of integrated circuits is expressly
prohibited. Tenant shall be responsible, at Tenant’s sole cost and expense, to provide all permits required by the City of Menlo Park and County of San Mateo in connection with such animal research. The use of any laboratory animals other than
laboratory mice, rats or hamsters in the Premises is subject to the prior written approval of Landlord, which approval may be withheld in Landlord’s sole discretion. Any use of the Premises by Tenant or by any sublessee or assignee approved by
Landlord pursuant to Paragraph 16 shall comply with the provisions of this Paragraph 7.

Exhibit “E” attached hereto and incorporated by reference herein, and any ordinary and customary office supplies, cleaning materials, and other materials reasonably required to be used in the normal course of Tenant’s agreed
use of the Premises, so long as such use is in compliance with all Environmental Laws, and does not expose the Premises, or the Property, or neighboring property to any unusual or atypical risk of contamination or damage or expose Landlord to any
liability therefor. If Tenant’s use of Hazardous Materials changes during the Term of this Lease (as may be extended), Tenant shall complete, execute, and deliver to Landlord, a Hazardous Materials Disclosure Certificate (“HazMat
Certificate”), a copy of which is attached as Exhibit “F”, attached hereto and incorporated by reference herein, describing Tenant’s present use of the Hazardous Materials on the Premises, and any other reasonably
necessary documents as requested by Landlord. The HazMat Certificate required hereunder shall be in substantially the form as that which is attached hereto as Exhibit “F.” In addition, Landlord may condition its consent to any
Reportable Use upon receiving such additional assurances as Landlord reasonably deems necessary to protect itself, the public, the Premises and the Property, and/or the environment against damage, contamination, injury and/or liability, including,
but not limited to, the installation (and removal on or before Lease expiration or termination) of any protective modifications installed by Tenant (such as concrete encasements). Landlord hereby covenants and agrees that any and all information

the request or order of any statutory, regulatory or supervisory authority with whom Landlord regularly complies, or as may be necessary for Landlord to enforce its rights and remedies under this Lease. 

(c) “Environmental Laws” shall mean and include any Federal, State, or local statute, law, ordinance, code, rule, regulation,

 (d) If Tenant knows, or has reasonable cause to believe, that Hazardous Materials have come
to be located in, on, under or about the Premises or the Property that constitutes a Reportable Use, other than as previously consented to by Landlord, Tenant shall immediately give written notice of such fact to Landlord and provide Landlord with a
copy of any report, notice, claim or other documentation which it has, concerning the presence of such Hazardous Materials. 
 (e) Tenant and
Tenant’s agents, employees, and contractors shall not cause any Hazardous Materials to be discharged or released into the Building or into the plumbing or sewage system of the Building or into or onto the Land underlying or adjacent to the
Building in violation of any Environmental Laws. Tenant shall promptly, at Tenant’s expense, take all investigatory and/or remedial action reasonably recommended, whether or not formally ordered or required, for the cleanup of any contamination
in violation of Environmental Laws or the terms of this Lease caused by Tenant or caused by any of Tenant’s employees, agents, or contractors, and for the maintenance, security and/or monitoring of the Premises, the Property, or neighboring
properties if such contamination is caused by a release or emission of any Hazardous Materials by Tenant or by any of Tenant’s employees, agents, or contractors. 

(f) Tenant shall indemnify, defend and hold Landlord and its agents, employees, and lenders and the Premises and the Property harmless from any
and all claims, damages, fines, judgments, penalties, costs, liabilities or losses (including, without limitation, any and all sums paid for settlement of claims, attorneys’ fees, consultant and expert fees) arising during or after the Term of
this Lease (as may be extended) out of or involving any Hazardous Materials brought on to the Premises, the Property, or Menlo Business Park by or for Tenant or by anyone under Tenant’s control in violation of Environmental Laws or the terms of
this Lease. Tenant’s obligations under this Paragraph 8(f) shall include, but not be limited to, the effects of any contamination or injury to person, property or the environment created or suffered by Tenant, and the cost of investigation
(including consultants’ and attorneys’ fees and testing), removal, remediation, restoration and/or abatement thereof, or of any contamination therein involved, as required by Environmental Laws, and shall survive the expiration or earlier
termination of this Lease. No termination, cancellation or release agreement entered into by Landlord and Tenant shall release Tenant from its obligations under this Lease with respect to Hazardous Materials, unless specifically so agreed by
Landlord in writing at the time of such agreement. 
 (g) Landlord shall indemnify, defend and hold Tenant and its agents, employees, and
contractors harmless from any and all claims, damages, fines, judgments, penalties, costs, liabilities or losses (including, without limitation, any and all sums paid for settlement of claims, attorneys’ fees, consultant and expert fees)
arising prior during or after the Term of this Lease out of or involving any Hazardous Materials existing on, in or under the Premises, the Property, or Menlo Business Park as of the Commencement Date, or brought on to the Premises, the Property, or
Menlo Business Park by or for Landlord or by anyone under Landlord’s control, in violation of Environmental Laws. Landlord’s obligations under this Paragraph 8(g) shall include, but not be limited to, the effects of any contamination or
injury to person, property or the environment created or suffered by Tenant, and the cost of investigation (including consultants’ and attorneys’ fees and testing), removal, remediation, restoration and/or abatement thereof, or of any
contamination therein involved, as required by Environmental Laws, and shall survive the expiration or earlier termination of this Lease. No termination, cancellation or release agreement entered into by Landlord and Tenant shall release Landlord
from its obligations under this Lease with respect to Hazardous Materials, unless specifically so agreed by Tenant in writing at the time of such agreement. 

  
 15 












 (h) The terms of this Paragraph 8 shall survive the expiration or earlier termination of
this Lease. 
 9. Taxes on Tenant’s Property. Tenant shall pay before delinquency any and all taxes, assessments, license fees, and
public charges levied, assessed, or imposed and which become payable during the Term and any extension thereof upon Tenant’s equipment, fixtures, furniture, and personal property installed or located on the Premises. 

 

	10.	 Insurance. 



(a) Types of Insurance: Tenant shall maintain in full force and effect at all times during the Term of this Lease and any extension thereof, at
Tenant’s sole cost and expense, for the protection of Tenant and Landlord, as their interests may appear, policies of insurance issued by a carrier or carriers reasonably acceptable to Landlord and its lender(s) which afford the following
coverages: 
 (i) Commercial general liability insurance naming the Landlord as an additional insured against any and all claims for bodily
injury and property damage occurring in, or about the Premises arising out of Tenant’s use and occupancy of the Premises. Such insurance shall have a combined single limit of not less than One Million Dollars ($1,000,000) per occurrence with a
Two Million Dollar ($2,000,000) aggregate limit and excess umbrella liability insurance in the amount of Five Million Dollars ($5,000,000). Such liability insurance shall be primary and not contributing to any insurance available to Landlord and
Landlord’s insurance shall be in excess thereto. In no event shall the limits of such insurance be considered as limiting the liability of Tenant under this Lease. 

(ii) Personal property insurance insuring all equipment, trade fixtures, inventory, fixtures, and personal property located on or in the
Premises for perils covered by the causes of loss—special form (all risk) and in addition, coverage for flood, wind, earthquake, terrorism and boiler and machinery (if applicable). Such insurance shall be written on a replacement cost basis in
an amount equal to one hundred percent (100%) of the full replacement value of the aggregate of the foregoing. 
 (iii) Business interruption
and extra expense insurance in such amounts to reimburse Tenant for direct or indirect loss attributable to all perils commonly insured against by prudent Tenants or attributable to prevention of access to the Premises or the Building as result of
such perils. 
 (iv) Workers’ compensation insurance in accordance with statutory law and employers’ liability insurance with a
limit of not less than $1,000,000 per accident, $1,000,000 disease, policy limit and $1,000,000 disease limit each employee. 
 (v) Such
other insurance as Landlord deems necessary and prudent or required by Landlord’s beneficiaries or mortgagees of any deed of trust or mortgage encumbering the Premises. 

  
 16 












 (b) Insurance Policies: The policies required to be maintained by Tenant shall be with
companies rated A-X or better by A.M. Best. Insurers shall be licensed to do business in the state in which the Premises are located and domiciled in the USA. Any deductible amounts under any insurance
policies required hereunder shall not exceed $1,000. Certificates of insurance (certified copies of the policies may be required) shall be delivered to Landlord prior to the commencement date and annually thereafter at least thirty (30) days
prior to the policy expiration date. Tenant shall have the right to provide insurance coverage which it is obligated to carry pursuant to the terms hereof in a blanket policy, provided such blanket policy expressly affords coverage to the Premises
and to Landlord as required by this Lease. Each policy of insurance shall provide notification to Landlord at least thirty (30) days prior to any cancellation or modification to reduce the insurance coverage. 

(c) Additional Insureds and Coverage: Landlord, any property management company and/or agent of Landlord for the Premises, the Building, the
Lot or the Park, and any lender(s) of Landlord having a lien against the Premises, the Building, the Lot or the Park shall be named as additional insureds under all of the policies required in Section 10(a) above. Additionally, such policies
shall provide for severability of interest. All insurance to be maintained by Tenant shall, except for workers’ compensation and employer’s liability insurance, be primary, without right of contribution from insurance maintained by
Landlord. Any umbrella/excess liability policy (which shall be in “following form”) shall provide that if the underlying aggregate is exhausted, the excess coverage will drop down as primary insurance. The limits of insurance maintained by
Tenant shall not limit Tenant’s liability under this Lease. It is the parties’ intention that the insurance to be procured and maintained by Tenant as required herein shall provide coverage for any and all damage or injury arising from or
related to Tenant’s operations of its business and/or Tenant’s or Tenant’s Representatives’ use of the Premises and/or any of the areas within the Park, whether such events occur within the Premises (as described in Exhibit
“A” hereto) or in any other areas of the Park. It is not contemplated or anticipated by the parties that the aforementioned risks of loss be borne by Landlord’s insurance carriers, rather it is contemplated and anticipated by
Landlord and Tenant that such risks of loss be borne by Tenant’s insurance carriers pursuant to the insurance policies procured and maintained by Tenant as required herein. 

(d) Failure of Tenant to Purchase and Maintain Insurance: In the event Tenant does not purchase the insurance required in this Lease or keep
the same in full force and effect throughout the Term of this Lease (including any renewals or extensions), Landlord may, but without obligation to do so, purchase the necessary insurance and pay the premiums therefor. If Landlord so elects to
purchase such insurance, Tenant shall promptly pay to Landlord as Additional Rent, the amount so paid by Landlord, upon Landlord’s demand therefor. In addition, Landlord may recover from Tenant and Tenant agrees to pay, as Additional Rent, any
and all Enforcement Expenses and damages which Landlord may sustain by reason of Tenant’s failure to obtain and maintain such insurance. If Tenant fails to maintain any insurance required in this Lease, Tenant shall be liable for all losses,
damages and costs resulting from such failure. 

  
 17 












 (e) Landlord’s Insurance: Landlord shall obtain and carry in Landlord’s name, as
insured, as an Operating Expense of the Property to the extent provided in Paragraph 4, during the Term (including any renewals or extensions), “all risk” property insurance coverage (with rental loss insurance coverage for a period of one
(1) year), flood insurance, public liability and property damage insurance, and insurance against such other risks or casualties as Landlord shall reasonably determine, including, but not limited to, insurance coverages required of Landlord by
the beneficiary of any deed of trust which encumbers the Premises, including earthquake insurance coverage insuring Landlord’s interest in the Premises (including any other leasehold improvements to the Premises constructed by Landlord or by
Tenant with Landlord’s prior written approval) in an amount not less than the full replacement cost of the Building. The proceeds of any such insurance shall be payable solely to Landlord and Tenant shall have no right or interest therein.
Landlord shall have no obligation to insure against loss by Tenant to Tenant’s equipment, fixtures, furniture, inventory, or other personal property of Tenant in or about the Premises occurring from any cause whatsoever. 

(f) Waiver of Subrogation: Notwithstanding anything to the contrary contained in this Lease, the parties release each other, and their
respective authorized representatives, employees, officers, directors, shareholders, managers, members, trustees, beneficiaries, assignees, subtenants, invitees, successors, agents, contractors and property managers, from any claims for damage to
any person or to the Premises or the Property and to the fixtures, personal property, leasehold improvements and alterations of either Landlord or Tenant in or on the Premises or the Property, to the extent that are caused by or result from risks
required by this Lease to be insured against (or actually insured against) under any property insurance policies carried by the parties and such policy is in force at the time of any such damage, whichever is greater. This waiver applies whether or
not the loss is due to the negligent acts or omissions of Landlord or Tenant or their respective authorized representatives, employees, officers, directors, shareholders, managers, members, trustees, beneficiaries, assignees, subtenants, invitees,
successors, agents, contractors and property managers. Subject to the foregoing, this release and waiver shall be complete and total even if such loss or damage may have been caused by the negligence of the other party, its managers, members,
employees, agents, contractors, property managers or invitees. Tenant covenants that the insurance policies required to be maintained by Tenant under this Lease will contain waiver of subrogation endorsements. 

11. Indemnification. Tenant shall indemnify, defend, and hold harmless Landlord from claims, suits, actions, or liabilities for personal injury, death
or for loss or damage to property that arise from (1) any activity, work, or thing done or permitted by Tenant in or about the Premises, the Property or the Park, (2) bodily injury or damage to property which arises in or about the
Property to the extent the injury or damage to property results from the acts or omissions of Tenant, its employees, agents or contractors, or (3) based on any event of default by Tenant in the performance of any obligation on Tenant’s
part to be performed under this Lease. Tenant also waives all claims against Landlord and its employees, agents and contractors for damages to property, or to goods, wares, and merchandise stored in, upon, or about the Premises or the Property, and
for injuries to persons in, upon, or about the Premises or the Property from any cause arising at any time, except to the extent covered by an express indemnity provision of this Lease or caused by the active negligence or willful misconduct of
Landlord or its employees, agents or contractors. 
 (a) Landlord shall indemnify, defend, and hold harmless Tenant from claims, suits,
actions, or liabilities for personal injury, death or for loss or damage to property to the extent arising from (1) any activity, work, or thing done by Landlord in or about the Premises or the Property, (2) breach by Landlord in the
performance of any obligation on Landlord’s part to be performed under this Lease beyond all applicable cure periods without cure, or (3) bodily injury or damage to property which arises in or about the Property to the extent the injury or
damage to property results from the active negligent acts of Landlord, its employees, agents or contractors. 

  
 18 












 (b) In the absence of comparative or concurrent negligence on the part of Tenant or
Landlord, their respective agents, affiliates, and subsidiaries, or their respective officers, directors, members, employees or contractors, the foregoing indemnities by Tenant and Landlord shall also include reasonable costs, expenses and
attorneys’ fees incurred in connection with any indemnified claim or incurred by the indemnitee in successfully establishing the right to indemnity. The indemnitor shall have the right to assume the defense of any claim subject to the foregoing
indemnities with counsel reasonably satisfactory to the indemnitee. The indemnitee agrees to cooperate fully with the indemnitor and its counsel in any matter where the indemnitor elects to defend, provided the indemnitor shall promptly reimburse
the indemnitee for reasonable costs and expenses incurred in connection with its duty to cooperate. 
 The foregoing indemnities shall
survive the expiration or earlier termination of this Lease and are conditioned upon the indemnitee providing prompt notice to the indemnitor of any claim or occurrence that is likely to give rise to a claim, suit, action or liability that will fall
within the scope of the foregoing indemnities, along with sufficient details that will enable the indemnitor to make a reasonable investigation of the claim. 

When the claim is caused by the joint negligence or willful misconduct of Tenant and Landlord or by the indemnitor party and a third party
unrelated to the indemnitor party (except indemnitor’s agents, officers, employees or invitees), the indemnitor’s duty to indemnify and defend shall be proportionate to the indemnitor’s allocable share of joint negligence or willful
misconduct. 
 (c) Landlord shall not be liable to Tenant for any damage because of any act or negligence of any other occupant of the
Building or any other owner or occupant of adjoining or contiguous property, nor for overflow, breakage, or leakage of water, steam, gas, or electricity from pipes, wires, or otherwise in the Premises or the Building, except to the extent caused by
the gross negligence or willful misconduct of Landlord or Landlord’s employees, agents, or contractors. Except as otherwise provided herein, Tenant will pay for damage to the Premises or the Property caused by the misuse or neglect of the
Premises or the Property by Tenant or its employees, agents, or contractors, including, but not limited to, the breakage of glass in the Building.

 13. Maintenance and Repairs; Alterations; Surrender and Restoration. 

(a) Landlord shall, at Landlord’s sole expense, keep in good order, condition, and repair and replace when necessary, the structural
elements of the roof (excluding the roof membrane which Landlord shall maintain, but the cost of which shall be included as an Operating Expense as permitted under Paragraph 4), the structural elements of the foundation and exterior walls (except
the interior faces thereof) of the Building, and other structural elements of the Building and the Property as “structural elements” are defined in building codes applicable to the Building, excluding any alterations, structural or
otherwise, made by Tenant to the Building which are not approved in writing by Landlord prior to the construction or installation thereof by Tenant. Landlord shall perform and construct, and Tenant shall not be responsible for performing or
constructing, any repairs, maintenance, or improvements (1) required as a result of any casualty damage (not caused by the willful or negligent acts or omissions of Tenant or its employees, agents, contractors or invitees), which shall be
subject to Paragraph 19 below, or as a result of any taking pursuant to the exercise of the power of eminent domain, or (2) for which Landlord has a right of reimbursement from third parties based on construction or other warranties, contractor
guarantees, or insurance claims. 
 (b) Landlord shall provide or cause to be provided and shall supervise the performance of, as an
Operating Expense of the Property to the extent permitted under Paragraph 4 hereof, all services and work relating to the operation, maintenance, repair, and replacement, as needed, of the Property, including the HVAC, mechanical, electrical, and
plumbing systems in the Building; the interior of the Building; the roof membrane; the outside areas of the Property; the janitorial service for the Building; landscaping, tree trimming, resurfacing and restriping of the parking lot, repairing and
maintaining the walkways; exterior building painting, exterior building lighting, parking lot lighting, and exterior security patrol. In the event Tenant provides Landlord with written notice of the need for any repairs, Landlord shall commence any
such repairs promptly following receipt by Landlord of such notice and Landlord shall diligently prosecute such repairs to completion. 
 (c)
Subject to the foregoing and except as provided elsewhere in this Lease, Tenant shall at all times use and occupy the Premises in a manner which keeps the Premises in good and safe order, condition, and repair. Landlord shall execute and maintain in
full force and effect throughout the term as an Operating Expense of the Property to the extent permitted under Paragraph 4 a service contract with a recognized air conditioning service company. Landlord may, if Landlord determines that it is
necessary to do so, obtain on a semi-annual basis an inspection report of the HVAC system from a separate HVAC service firm designated by Landlord for the purpose of monitoring the performance of the HVAC maintenance and repair work performed by the
HVAC service firm which performs the regular repair and maintenance. The cost of such inspection report shall be an Operating Expense pursuant to Paragraph 4. Subject to the release of claims and waiver of subrogation contained in Paragraph 10(f),
if Landlord is required to make any repairs to the Property by reason of Tenant’s negligent acts or omissions, Landlord may add the cost of such repairs to the next installment of rent which shall thereafter become due, and Tenant shall
promptly pay the same upon receipt of an invoice therefor. 

  
 20 












 (d) Tenant may, from time to time, at its own cost and expense and without the consent of
Landlord, make nonstructural alterations to the interior of the Premises that do not affect the Building systems, including without limitation, the HVAC, life-safety, mechanical, electrical, and plumbing systems in the Building, and the cost of
which in any one instance is Fifty Thousand Dollars ($50,000) or less, and the aggregate cost of all such work during the Term this Lease (as may be extended) does not exceed One Hundred Thousand Dollars ($100,000), provided Tenant first notifies
Landlord in writing of any such nonstructural alterations. Otherwise, Tenant shall not make any additional alterations, improvements, or additions to the Premises without delivering to Landlord a complete set of plans and specifications for such
work, obtaining and delivering copies to Landlord of all permits or other governmental approvals required for such work and obtaining Landlord’s prior written consent thereto. All alterations and additions requiring Landlord’s prior
written consent shall be installed by a licensed contractor reasonably approved by Landlord, at Tenant’s sole cost and expense and in compliance with all applicable laws, rules, regulations and ordinances. Tenant shall keep the Premises and the
Property on which the Premises are situated free from any liens arising out of any work performed, materials furnished or obligations incurred by or on behalf of Tenant. If any nonstructural alterations to the interior of the Premises exceed Fifty
Thousand Dollars ($50,000) in cost in any one instance, or exceed the aggregate cost of One Hundred Thousand Dollars ($100,000) during the Term of this Lease (as may be extended), Tenant shall employ, at Tenant’s expense, Tarlton Properties,
Inc. as construction manager for such alterations at a fee equal to four point five percent (4.5%) of the first Two Hundred Fifty Thousand Dollars ($250,000) of hard construction costs (i.e., the amounts paid to any general contractor,
subcontractors, vendors, and suppliers for labor and materials for the construction of the alterations or improvements) and then four percent (4%) of such hard construction costs in excess of Two Hundred Fifty Thousand Dollars ($250,000). Landlord
may condition its consent to, among other things, Tenant agreeing in writing to remove any such alterations prior to the expiration of the Lease term and Tenant agreeing to restore the Premises to its condition prior to such alterations at
Tenant’s expense. Upon Tenant’s written request, Landlord shall advise Tenant in writing at the time consent is granted whether Landlord reserves the right to require Tenant to remove any alterations from the Premises prior to the
expiration or sooner termination of this Lease. 
 All alterations, trade fixtures and personal property installed in the Premises solely at
Tenant’s expense shall during the term of this Lease remain Tenant’s property and Tenant shall be entitled to all depreciation, amortization and other tax benefits with respect thereto (excluding the Tenant Improvements). 

(e) Tenant shall, at Tenant’s sole cost and expense, fully, diligently and in a timely manner, comply with all present and future
“Laws,” which term is used in this Lease to mean all laws, rules, regulations, ordinances, directives, orders, covenants, permits of all governmental agencies and authorities, easements and restrictions of record, the requirements of any
applicable fire insurance underwriter or rating bureau or board of fire underwriters, relating in any manner to the Premises and/or Tenant’s use or occupancy of the Premises (including but not limited to matters pertaining to industrial
hygiene, environmental conditions on, in, under or about the Premises, including soil and groundwater conditions, subject to the provisions of Paragraph 8 hereof, and the use, generation, manufacture, production, installation, maintenance, removal,
transportation, storage, spill, or release of any Hazardous Materials (which are addressed in Paragraph 8 hereof)), now in effect or which may hereafter come into effect. Tenant shall, within five (5) days after receipt of Landlord’s
written request, provide Landlord with copies of all documents and information, including but not limited to permits, registrations, manifests, applications, reports and certificates, evidencing Tenant’s compliance with any Laws specified by
Landlord, and shall immediately upon receipt, notify Landlord in writing (with copies of any documents involved) of any threatened or actual claim, notice, citation, warning, complaint or report pertaining to or involving failure by Tenant or the
Premises to comply with any Laws. Notwithstanding the foregoing, any structural changes or repairs or other changes or repairs to the Property of any nature which would be considered a capital expenditure under generally accepted accounting
principles to the Premises shall be made by Landlord at Tenant’s expense if such structural repairs or changes are required by reason of the specific nature of the use of the Premises by Tenant. If such changes or repairs are not required by
reason of the specific nature of Tenant’s use of the Premises and are capital expenditures, the cost of such changes or repairs shall be treated as an Operating Expense and amortized in accordance with the provisions of Paragraph 4(b). 

  
 21 












 (f) Subject to Paragraph 30, Landlord, Landlord’s agents, employees, contractors and
designated representatives, and the holders of any mortgages, deeds of trust or ground leases on the Premises (“Lenders”) shall have the right to enter the Premises at any time in the case of an emergency, and otherwise at
reasonable times after at least 24 hours prior notice to Tenant, for the purpose of inspecting the condition of the Premises and for verifying compliance by Tenant with this Lease and all Laws, and Landlord shall be entitled to employ experts and/or
consultants in connection therewith to advise Landlord with respect to Tenant’s activities, including but not limited to Tenant’s installation, operation, use, monitoring, maintenance, or removal of any Hazardous Substance on or from the
Premises. The costs and expenses of any such inspections shall be paid by the party requesting same, unless a default or breach of this Lease by Tenant or a violation of Laws or a contamination, caused or materially contributed to by Tenant, is
found to exist or to be imminent, or unless the inspection is requested or ordered by a governmental authority as the result of any such existing or imminent violation or contamination. In such case, Tenant shall upon request reimburse Landlord or
Landlord’s Lender, as the case may be, for the costs and expenses of such inspections. In connection with the provision of janitorial services, Landlord shall comply with reasonable access restrictions established by Tenant from time to time
with respect to the animal facility where Tenant’s laboratory mice are kept in the Premises; provided, however, Landlord shall have access to such facility in the case of an emergency. 

(g) During the term of this Lease, Tenant shall comply, at Tenant’s expense, with all of the covenants, conditions, and restrictions
affecting the Premises which are recorded in the Official Records of San Mateo County, California, and which are in effect as of the date of this Lease. 

(h) Tenant shall surrender the Premises by the last day of the lease Term (as may be extended) or any earlier termination date, with all of the
improvements to the Premises, parts, and surfaces thereof clean and free of debris and in good operating order, condition, and state of repair, ordinary wear and tear excepted. Tenant’s failure to surrender the Premises in accordance with the
terms and conditions of this Lease, including, without limitation, this Paragraph 13(h) shall be deemed to be a material default under the Lease. “Ordinary wear and tear” shall not include any damage or deterioration that would have been
prevented by good maintenance practice or by Tenant performing all of its obligations under this Lease. Notwithstanding the foregoing, prior to the last day of the Term, as may be extended, (or earlier termination of the Lease), Tenant shall
(i) restore all walls in the Premises to the same condition existing immediately following completion of the Tenant Improvements, including patching and sanding all holes to match the original texture of the walls and painting; and
(ii) vacuum and steam clean all carpets and remove all stains. In addition to the foregoing, the obligations of Tenant shall include the repair of any damage occasioned by the installation, maintenance, or removal of Tenant’s trade
fixtures, furnishings, equipment, and alterations, and the restoration by Tenant of the Premises to its condition upon completion of the Tenant Improvements (Tenant shall not be required to remove any of the Tenant Improvements) (A) if
Landlord’s consent to alteration, additions or improvements was conditioned upon such removal and restoration upon expiration or sooner termination of the Lease term, or (B) if Tenant made any such alterations, additions, or improvements
without obtaining Landlord’s prior written consent, and within a reasonable time after the expiration or sooner termination of the Lease term Landlord gives written notice to Tenant requiring Tenant to perform such removal and restoration.
Subject to the foregoing, upon the expiration or sooner termination of this Lease all alterations, fixtures and improvements to the Premises, whether made by Landlord or installed by Tenant at Tenant’s expense, shall be surrendered by Tenant
with the Premises and shall become the property of Landlord; provided, however, that Tenant’s furniture and other personal property, not provided by or paid for by Landlord and not permanently affixed to the Premises which can be removed
without damaging the Premises may be removed by Tenant. Tenant shall repair to Landlord’s reasonable satisfaction all damage to the Premises occasioned by removal of Tenant’s Property. Prior to the expiration of the term of this Lease or
any earlier termination date, Tenant shall, at Tenant’s expense, obtain written closure reports from the San Mateo County Health Department and from the Menlo Park Fire Protection District with respect to any Hazardous Materials used, stored,
or released by Tenant on or about the Premises. Both written closure reports shall provide written certification that all Hazardous Materials have been removed from the Premises and that no further action is required in connection with the closure
of the Premises. Any removal and remediation of Hazardous Materials by Tenant shall be certified in writing as (1) complete and (2) having been properly performed, by the San Mateo County Health Department and the Menlo Park Fire
Protection District and a copy of such written certifications shall be delivered by Tenant to Landlord no later than the last day of the Term of this Lease (as may be extended). 

  
 22 












 (i) Tenant waives all right to make repairs at the expense of Landlord, or to deduct the
costs thereof from the rent, and Tenant waives all rights under Section 1941 and 1942 of the Civil Code of the State of California. 

(j) Compliance with Americans with Disabilities Act: Landlord and Tenant hereby agree and acknowledge that the Premises, the Building and/or
the Menlo Business Park may be subject to the requirements of the Americans with Disabilities Act, a federal law codified at 42 U.S.C. 12101 et seq, including, but not limited to Title III thereof, all regulations and guidelines related thereto,
together with any and all Laws now or hereafter enacted by local or state agencies having jurisdiction thereof, including all requirements of Title 24 of the State of California, as the same may be in effect on the date of this Lease and may be
hereafter modified, amended or supplemented (collectively, the “ADA”). Any Tenant Improvements to be constructed hereunder shall be in compliance with the requirements of the ADA, and all costs incurred for purposes of compliance
therewith shall be a part of and included in the costs of the Tenant Improvements. Tenant shall be solely responsible for conducting its own independent investigation of this matter and for ensuring that the design of all Tenant Improvements
strictly comply with all requirements of the ADA. Subject to reimbursement pursuant to Paragraph 5 of the Lease, if any barrier removal work or other work is required to the Building, the Common Areas or the Menlo Business Park under the ADA, then
such work shall be the responsibility of Landlord; provided, if such work is required under the ADA as a result of Tenant’s specific use of the Premises or any work or alteration made to the Premises by or on behalf of Tenant, then such work
shall be performed by Landlord at the sole cost and expense of Tenant. Except as otherwise expressly provided in this provision, Tenant shall be responsible at its sole cost and expense for fully and faithfully complying with all applicable
requirements of the ADA, including without limitation, not discriminating against any disabled persons in the operation of Tenant’s business in or about the Premises, and offering or otherwise providing auxiliary aids and services as, and when,
required by the ADA. Within ten (10) days after receipt, Landlord and Tenant shall advise the other party in writing, and provide the other with copies of (as applicable), any notices alleging violation of the ADA relating to any portion of the
Premises or the Building; any claims made or threatened in writing regarding noncompliance with the ADA and relating to any portion of the Premises or the Building; or any governmental or regulatory actions or investigations instituted or threatened
regarding noncompliance with the ADA and relating to any portion of the Premises or the Building. Tenant shall and hereby agrees to protect, defend (with counsel reasonably acceptable to Landlord) and hold Landlord and the other Indemnitees harmless
and indemnify the Indemnitees from and against all liabilities, damages, claims, losses, penalties, judgments, charges and expenses (including reasonable attorneys’ fees, costs of court and expenses necessary in the prosecution or defense of
any litigation including the enforcement of this provision) arising from or in any way related to, directly or indirectly, Tenant’s or Tenant’s Representatives’ violation or alleged violation of the ADA. Tenant agrees that the
obligations of Tenant herein shall survive the expiration or earlier termination of this Lease. 

  
 23 












 (k) CASp Disclosure: For purposes of Section 1938 of the California Civil Code,
Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that (check one): 
 To Landlord’s actual knowledge, the Premises
have undergone inspection by a Certified Access Specialist (CASp). 
 If the Premises have undergone inspection by a CASp prior to the
execution of this Lease and, to the best of Landlord’s knowledge, there have been no modifications or alterations completed or commenced between the date of the inspection and the date of this Lease which have impacted the Premises’
compliance with construction-related accessibility standards, Section 1938 requires Landlord to provide to Tenant, prior to execution of this Lease, a copy of any report prepared by the CASp. If, prior to the date of this Lease, the Premises
were issued an inspection report by a CASp indicating that it meets applicable standards, as defined in paragraph (4) of subdivision (a) of California Civil Code Section 55.52, Landlord is required to provide a copy of the current
disability access inspection certificate and any inspection report to Tenant that was not already provided pursuant to the foregoing sentence, within seven (7) days of the date of the execution of this Lease. 

☒  To Landlord’s actual knowledge, the Premises have not undergone inspection by a CASp. 

or 
 ☐  To Landlord’s actual knowledge, the
Premises have undergone inspection by a CASP but, to the best of Landlord’s knowledge, there have been intervening modifications or alterations completed or commenced which have impacted the Premises compliance with construction related
accessibility standards. 
 California Civil Code Section 1938 states: 

“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 state law does not require a CASp inspection of the subject premises, the commercial property owner or Landlord may not prohibit the Tenant or tenant from obtaining a CASp
inspection of the subject premises for the occupancy or potential occupancy of the Tenant, if requested by the Tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for
the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the premises.” 

  
 24 












 Notwithstanding anything to the contrary in this Lease, Landlord and Tenant hereby agree that, during the
Term of this Lease (as may be extended), as the same may be extended, Tenant shall be responsible for (i) the payment of the fee for any CASp inspection that Tenant desires, and (ii) making, at Tenant’s cost, any repairs necessary to
correct violations of construction-related accessibility standards within the Premises provided that such repairs shall be in accordance with the terms of the Lease (as amended). Tenant hereby agrees that: any CASp inspecting the Premises shall be
selected by Landlord; Tenant shall promptly deliver to Landlord any CASp report regarding the Premises obtained by Tenant; and Tenant shall keep information contained in any CASp report regarding the Premises confidential, except as may be necessary
for Tenant or its agents to complete any repairs or correct violations with respect to the Premises that Tenant agrees to undertake. Tenant shall have no right to cancel or terminate the Lease (as amended) due to violations of construction-related
accessibility standards within the Premises identified in a CASp report obtained during the Term of the Lease (as may be extended). 
  

	14.	 Utilities and Services. 



(a) Landlord shall contract for and pay for, and Tenant shall reimburse Landlord therefor pursuant to Paragraph 4 as an Operating Expense, all
electricity, gas, water, heat and air conditioning service, janitorial service1, refuse pick-up, sewer charges, and all other utilities or services supplied
to or consumed by Tenant, its agents, employees, contractors, and invitees on or about the Premises, excluding telephone service to the Premises for which Tenant shall contract and pay directly. 

(b) Landlord shall not be liable to Tenant for any interruption or failure of any utility services to the Building or the Premises which is not
caused by the active negligence or willful acts of Landlord. Tenant shall not be relieved from the performance of any covenant or agreement in this Lease because of any such failure. Landlord shall make all repairs to the Premises required to
restore such services to the Premises and the cost thereof shall be payable by Tenant pursuant to Paragraph 4 as a current Operating Expense, or as a capital expense which is amortized over its useful life (together with interest thereon) as an
Operating Expense in accordance with generally accepted accounting principles as described in Paragraph 4(b); provided, however, if such failure is caused by the active negligence or willful acts of Landlord, then Landlord shall bear such costs.

  

	1 	 Note to Landlord: To discuss janitorial services. Landlord’s vendors cannot be permitted into the animal
lab. Also, Tenant may need to secure certain portions of the Premises as part of its safety protocols and confidentiality concerns. 



  
 25 












 (c) In the event that Tenant is permitted and elects to contract directly for the provision
of electricity, gas and/or water services to the Premises with the third-party provider thereof (all in Landlord’s reasonable discretion), Tenant shall within ten (10) business days following its receipt of written request from Landlord,
provide Landlord with a copy of each requested invoice 
 from the applicable utility provider. Tenant acknowledges that pursuant to California Public
Resources Code Section 25402.10 and the regulations adopted pursuant thereto (collectively, the “Energy Disclosure Requirements”), Landlord may be required to disclose information concerning Tenant’s energy usage at the
Building to certain third parties, including without limitation, prospective purchasers, lenders and Tenants of the Building (the “Tenant Energy Use Disclosure”). Tenant hereby (A) consents to all such Tenant Energy Use
Disclosures, and (B) acknowledges that Landlord shall not be required to notify Tenant of any Tenant Energy Use Disclosure. Further, Tenant hereby releases Landlord from any and all losses, costs, damages, expenses and liabilities relating to,
arising out of and/or resulting from any Tenant Energy Use Disclosure. The terms of this Paragraph shall survive the expiration or earlier termination of this Lease. 

15. Liens. Tenant agrees to keep the Premises free from all liens arising out of any work performed, materials furnished, or obligations incurred by
Tenant. Tenant shall give Landlord at least ten (10) calendar days prior written notice before commencing any work of improvement on the Premises, the contract price for which exceeds Ten Thousand Dollars ($10,000). Landlord shall have the
right to post notices of non-responsibility with respect to any such work. If Tenant shall, in good faith, contest the validity of any such lien, claim or demand, then Tenant shall, at its sole expense, defend
and protect itself, Landlord and the Property against the same, and shall pay and satisfy any such adverse judgment that may be rendered thereon before the enforcement thereof against the Landlord or the Property. If Landlord shall require, Tenant
shall furnish to Landlord a surety bond satisfactory to Landlord in an amount equal to one and one-half times the amount of such contested claim or demand, indemnifying Landlord against liability for the same,
as required by law for the holding of the Property free from the effect of such lien or claim. 
  

	16.	 Assignment and Subletting. 



(a) Except as otherwise provided in this Paragraph 16, Tenant shall not assign this Lease, or any interest, voluntarily or involuntarily, and
shall not sublet the Premises or any part thereof, or any right or privilege appurtenant thereto, or suffer any other person (the agents and servants of Tenant excepted) to occupy or use the Premises, or any portion thereof, without the prior
written consent of Landlord in each instance pursuant to the terms and conditions set forth below, which consent shall not be unreasonably withheld or delayed, subject to the following provisions; provided, however, Tenant shall not assign this
Lease, or any interest, voluntarily or involuntarily, and shall not sublet the Premises or any part thereof, or any right or privilege appurtenant thereto, or suffer any other person (the agents and servants of Tenant excepted) to occupy or use the
Premises, or any portion thereof, if Tenant shall be in default under this Lease past any applicable cure period. 

  
 26 












 (b) Prior to any assignment or sublease which Tenant desires to make, other than a Permitted
Transfer (as defined in Paragraph 16(f) below), Tenant shall provide to Landlord the name and address of the proposed assignee or sublessee, and true and complete copies of all documents relating to Tenant’s prospective agreement to assign or
sublease, a copy of a current financial statement for such proposed assignee or sublessee (or if unavailable, such other information as may be reasonably acceptable to Landlord with regard to the financial capacity of such proposed assignee or
sublessee), and any other relevant information requested by Landlord within five (5) days after receipt of notice of the proposed assignment or sublease and Tenant shall specify all consideration to be received by Tenant for such assignment or
sublease in the form of lump sum payments, installments of rent, or otherwise. For purposes of this Paragraph 16, the term “consideration” shall include all money or other consideration to be received by Tenant for such assignment or
sublease. Within ten (10) days after the receipt of such documentation and other information, Landlord (1) shall notify Tenant in writing that Landlord elects to consent to the proposed assignment or sublease subject to the terms and
conditions hereinafter set forth; (2) shall notify Tenant in writing that Landlord refuses such consent, specifying reasonable grounds for such refusal; or (3) except with respect to a Permitted Transferee, if at the time Tenant requests
that Landlord consent to an assignment or sublease Tenant has vacated thirty-three percent (33%) or more of the Premises and is not conducting on-going operations in the Building, and to the extent that any
proposed sublease is for the substantial remainder of the Term, Landlord may notify Tenant that Landlord elects to terminate this Lease, provided that with respect to a proposed sublease of a portion of the Premises Landlord’s termination right
shall apply only to the proposed sublease space, and specifying the effective date of termination which shall be the same as the commencement date of the proposed sublease. If Landlord elects to terminate this Lease pursuant to the foregoing
provision, upon the effective date of termination, Landlord and Tenant shall each be released and discharged from any liability or obligation to the other under this Lease accruing thereafter with respect to the Premises or the portion thereof to
which the termination applies, except for any obligations then outstanding and except for any indemnity obligations which survive the expiration or termination of this Lease by the express terms hereof, and Tenant agrees that Landlord may enter into
a direct lease with such proposed assignee or sublessee without any obligation or liability to Tenant. Notwithstanding the foregoing, or anything to the contrary contained herein, if Landlord exercises its option to terminate this Lease in
accordance with this Paragraph, then Tenant shall have the right to withdraw its request for consent by delivering written notice of such election within five (5) days after Landlord’s delivery of notice electing to exercise
Landlord’s option to terminate this Lease. In the event Tenant withdraws its request as provided in this Paragraph, then the Lease shall continue in full force and effect. No failure of Landlord to exercise its option to terminate this Lease
shall be deemed to be Landlord’s consent to a proposed assignment or sublease. 
 In deciding whether to consent to any proposed
assignment or sublease, Landlord may take into account whether reasonable conditions have been satisfied, including, but not limited to, the following: 

(1) In Landlord’s reasonable judgment, the proposed assignee or subtenant is engaged in such a business, that the Premises, or the
relevant part thereof, will be used in such a manner which complies with Paragraph 7 hereof entitled the “Permitted Use” and Tenant or the proposed assignee or sublessee submits to Landlord, documentary evidence reasonably satisfactory to
Landlord that such proposed use constitutes a permitted use of the Premises pursuant to the ordinances and regulations of the City of Menlo Park; 

(2) The proposed assignee or subtenant is a reputable entity or individual with sufficient financial net worth so as to reasonably indicate
that it will be able to meet its obligations under this Lease or the sublease in a timely manner; 
 (3) If at the time of the proposed
transfer, Landlord has substantially similar space available for rent in the Menlo Business Park, the proposed assignee or subtenant is not a tenant of the Building or any other building in the Menlo Business Park; and 

  
 27 












 (4) The proposed assignment or sublease is approved by Landlord’s mortgage lender if
such lender has the right to approve or disapprove proposed assignments or subleases. Landlord shall use its good faith efforts to obtain such approval from its lender within ten (10) days after receipt by Landlord of Tenant’s written
request for consent and the documentation and information referred to in the first sentence of Paragraph 16(b) above. 
 (c) As a condition
to Landlord’s granting its consent to any assignment or sublease, except with respect to any Permitted Transferees, (1) Landlord may require that Tenant pay to Landlord, as and when received by Tenant, fifty percent (50%) of the amount of
any excess of the consideration to be received by Tenant in connection with said assignment or sublease over and above the Monthly Base Rent and Additional Rent fixed by this Lease and payable by Tenant to Landlord, after deducting only (A) a
standard leasing commission payable by Tenant in consummating such assignment or sublease, (B) the cost of reasonable tenant improvements performed specifically for the sublease and required to be made to the Premises to effectuate the
sublease, provided that such improvements are performed in compliance with Paragraph 13(d) of this Lease, and (C) reasonable attorneys’ fees incurred by Landlord in negotiating and reviewing the assignment or sublease documentation; and
(2) Tenant and the proposed assignee or sublessee shall demonstrate to Landlord’s reasonable satisfaction that each of the criteria referred to in subparagraph (b) above is satisfied. 

(d) Each assignment or sublease agreement to which Landlord has consented shall be an instrument in writing in form satisfactory to Landlord,
and shall be executed by both Tenant and the assignee or sublessee, as the case may be. Each such assignment or sublease agreement shall recite that it is and shall be subject and subordinate to the provisions of this Lease, that the assignee or
sublessee accepts such assignment or sublease, that Landlord’s consent thereto shall not constitute a consent to any subsequent assignment or subletting by Tenant or the assignee or sublessee, and, except as otherwise set forth in a sublease
approved by Landlord, agrees to perform all of the obligations of Tenant hereunder (to the extent such obligations relate to the portion of the Premises assigned or subleased), and that the termination of this Lease shall, at Landlord’s sole
election, constitute a termination of every such assignment or sublease. 
 (e) In the event Landlord shall consent to an assignment or
sublease, Tenant shall nonetheless remain primarily liable for all obligations and liabilities of Tenant under this Lease, including but not limited to the payment of rent. 

(f) Notwithstanding the foregoing, Tenant may, without Landlord’s prior written consent and without any participation by Landlord in
assignment and subletting proceeds, but with prior notice and documentation, as required pursuant to this Paragraph 16(f), provided to Landlord, sublet a portion or the entire Premises or assign this Lease to (i) a subsidiary, affiliate,
division or corporation controlled or under common control with Tenant (“affiliate”); (ii) to a successor corporation related to Tenant by merger, consolidation or reorganization; or (iii) to a purchaser of substantially all of
Tenant’s business operations conducted on the Premises (each such transaction referred to herein as a “Permitted Transfer” and each of the foregoing transferees referred to herein as a “Permitted Transferee”),
provided that any such Permitted Transferee shall have a current verifiable net worth prior to the transfer at least equal to that of Tenant on the Commencement Date of this Lease, or, if less, financial resources sufficient, in Landlord’s
reasonable good faith judgment, to perform the obligations under the assignment or sublease, as applicable. Tenant’s foregoing rights in this Paragraph 16(f) to assign this Lease or to sublease all or a portion of the entire Premises shall be
subject to the following conditions: (1) Tenant shall not be in default hereunder past any applicable cure period; (2) in the case of an assignment or subletting to an affiliate, Tenant shall remain liable to Landlord hereunder if Tenant
is a surviving entity; (3) the transferee or successor entity shall expressly assume in writing all of Tenant’s obligations hereunder; and (4) Tenant shall provide Landlord with prior notice of such proposed transfer and deliver to
Landlord all documents reasonably requested by Landlord relating to such transfer, including but not limited to documentation sufficient to establish such proposed transferee’s current verifiable net worth prior to the transfer at least equal
to that of Tenant on the Commencement Date of this Lease, or, if less, financial resources sufficient, in Landlord’s reasonable good faith judgment, to perform the obligations under the assignment or sublease, as applicable. 

  
 28 












 (g) Neither the sale nor transfer of Tenant’s capital stock shall be deemed an
assignment, subletting, or other transfer of this Lease or the Premises, provided, that in the event of the sale, transfer or issuance of Tenant’s securities to an affiliate or in connection with a transaction described in Paragraph 16(f), the
conditions set forth in Paragraph 16(f) shall apply. 
 (h) Subject to the provisions of this Paragraph 16 any assignment or sublease (if
such consent is required hereunder) without Landlord’s prior written consent shall at Landlord’s election be void. The consent by Landlord to any assignment or sublease shall not constitute a waiver of the provisions of this Paragraph 16,
including the requirement of Landlord’s prior written consent, with respect to any subsequent assignment or sublease. If Tenant shall purport to assign this Lease, or sublease all or any portion of the Premises, or permit any person or persons
other than Tenant to occupy the Premises, without Landlord’s prior written consent (if such consent is required hereunder), Landlord may collect rent from the person or persons then or thereafter occupying the Premises and apply the net amount
collected to the rent reserved herein, but no such collection shall be deemed a waiver of Landlord’s rights and remedies under this Paragraph 16, or the acceptance of any such purported assignee, sublessee, or occupant, or a release of Tenant
from the further performance by Tenant of covenants on the part of Tenant herein contained. 
 (i) Tenant shall not hypothecate or encumber
its interest under this Lease or any rights of Tenant hereunder, or enter into any license or concession agreement respecting all or any portion of the Premises, without Landlord’s prior written consent which consent Landlord may grant or
withhold in Landlord’s absolute discretion without any liability to Tenant. Tenant’s granting of any such encumbrance, license, or concession agreement shall constitute an assignment for purposes of this Paragraph 16. 

(j) In the event of any sale or exchange of the Premises by Landlord and assignment of this Lease by Landlord, Landlord shall, upon providing
Tenant with written confirmation that the assignee has assumed all obligations of Landlord under this Lease and Landlord has delivered any Security Deposit held by Landlord to Landlord’s successor in interest, be and hereby is entirely relieved
of all liability under any and all of Landlord’s covenants and obligations contained in or derived from this Lease with respect to the period commencing with the consummation of the sale or exchange and assignment.

 (k) Tenant hereby acknowledges that the foregoing terms and conditions are reasonable and,
therefore, that Landlord has the remedy described in California Civil Code Section 1951.4 (Landlord may continue the Lease in effect after Tenant’s breach and abandonment and recover rent as it becomes due, if Tenant has the right to
sublet or assign, subject only to reasonable limitations). 
 17. Non-Waiver. 

(a) No waiver of any provision of this Lease shall be implied by any failure of Landlord to enforce any remedy for the violation of that
provision, even if that violation continues or is repeated. Any waiver by Landlord of any provision of this Lease must be in writing. 
 (b)
No receipt of Landlord of a lesser payment than the rent required under this Lease shall be considered to be other than on account of the earliest rent due, and no endorsement or statement on any check or letter accompanying a payment or check shall
be considered an accord and satisfaction. Landlord may accept checks or payments without prejudice to Landlord’s right to recover all amounts due and pursue all other remedies provided for in this Lease. 

Landlord’s receipt of any rent or other payment from Tenant after giving notice to Tenant terminating this Lease shall in no way
reinstate, continue, or extend the Lease term or affect the termination notice given by Landlord before the receipt of such rent or payment. After serving notice terminating this Lease, filing an action, or obtaining final judgment for possession of
the Premises, Landlord may receive and collect any rent, and the payment of that rent shall not waive or affect such prior notice, action, or judgment. 

18. Holding Over. Tenant shall vacate the Premises and deliver the same to Landlord upon the expiration or sooner termination of this Lease. In the
event of holding over by Tenant after the expiration or termination of this Lease, such holding over shall be on a month-to-month tenancy and all of the terms and
provisions of this Lease shall be applicable during such period, except that in addition to the payment of Additional Rent, Tenant shall pay Landlord as Monthly Base Rent during such holdover an amount equal to the greater of (i) one hundred
fifty percent (150%) of the Monthly Base Rent in effect at the expiration of the term, or (ii) the then market rent for comparable research and development/office space. If such holdover is without Landlord’s written consent, Tenant shall
be liable to Landlord for all costs, expenses, and consequential damages incurred by Landlord as a result of such holdover, including but not limited to damages resulting from Landlord’s inability to timely deliver possession of the Premises to
a new tenant. The rental payable during such holdover period without Landlord’s written consent shall be payable to Landlord on demand. 
 19. Damage
or Destruction. 
 (a) In the event of a total destruction of the Building during the term from any cause, either party may elect to
terminate this Lease by giving written notice of termination to the other party within thirty (30) days after the casualty occurs. A total destruction shall be deemed to have occurred for this purpose if the Building or the Premises that are
the subject of this Lease are destroyed to the extent of seventy-five percent (75%) or more of the replacement cost thereof. If the Lease is not terminated, Landlord shall repair and restore the Premises in a diligent manner and this Lease shall
continue in full force and effect, except that Monthly Base Rent and Additional Rent of the Premises which are the subject of this Lease shall be abated in accordance with Paragraph 19(d) below. 

  
 30 












 (b) In the event of a partial destruction of the Building or the Premises to an extent less
than seventy-five percent (75%) of the replacement cost thereof, and if Landlord reasonably believes that the damage thereto can be repaired, reconstructed, or restored within a period of two hundred seventy (270) days from the date of such
casualty, there are at least twelve (12) months remaining in the term of this Lease, and the casualty is from a cause which is insured under Landlord’s “all risk” property insurance, or is insured under any other coverage then
carried by Landlord, Landlord shall forthwith repair the same, and this Lease shall continue in full force and effect, except that Monthly Base Rent and Additional Rent shall be abated in accordance with Paragraph 19(d) below. If any of the
foregoing conditions are not met, Landlord shall have the option of either repairing and restoring the Building and Improvements, or terminating this Lease by giving written notice of termination to Tenant within sixty (60) days after the
casualty. Notwithstanding anything to the contrary contained in this Paragraph 20, Landlord shall not have the right to terminate this Lease if the cost to repair the damage to the Building or to restore the Premises would cost less than five
percent (5%) of the replacement cost of the Building, regardless of whether or not the casualty is insured provided that there are at least twelve (12) months remaining in the term of this Lease. 

(c) Landlord’s election to repair and restore the Building and Improvements or to terminate this Lease, shall be made and written notice
thereof shall be given to Tenant within sixty (60) days after the casualty. Notwithstanding the foregoing, (1) Tenant may terminate this Lease by written notice to Landlord if Landlord has not obtained all necessary governmental permits
for the restoration and commenced construction of the restoration within ninety (90) days after the casualty; or (2) if Landlord elects to repair and restore the Building and Improvements under Paragraph 19(b) above, but the repairs and
restoration are not substantially completed within two hundred seventy (270) days after the casualty plus the period of any force majeure delays (as defined in subparagraph (e)), Tenant may terminate this Lease by written notice to Landlord
given within thirty (30) days after the expiration of said period of two hundred seventy (270) days after the casualty, provided that the repairs and restoration are not substantially completed prior to the receipt by Landlord of such
notice of termination. 
 (d) In the event of repair, reconstruction, or restoration as provided herein, the Monthly Base Rent and Additional
Rent shall be abated proportionally in the ratio which the Tenant’s use of the Premises is completely impaired and Tenant does not use such portion of the Premises during the period of such repair, reconstruction, or restoration, from the date
of the casualty until such repair, reconstruction or restoration is substantially completed. 
 (e) With respect to any destruction of the
Building and Improvements which Landlord is obligated to repair, or may elect to repair, under the terms of this Paragraph 19, the provisions of Section 1932, Subdivision 2, and of Section 1933, Subdivision 4, of the Civil Code of the
State of California are waived by the parties. Landlord’s obligation to repair and restore the Building and Improvements shall include the Tenant Improvements referred to in Paragraph 12(a) up to the cost of the Tenant Improvement Allowance.
Landlord’s time for completion of the repairs and restoration of the Building and Improvements referred to above shall be extended by a period equal to any delays (“force majeure delays”) caused by strikes, labor disputes,
unavailability of materials, inclement weather, circumstances not within Landlord’s control, or acts of God, but in no event by more than sixty (60) days. 

  
 31 












 (f) In the event of termination of this Lease pursuant to any of the provisions of this
Paragraph 19, the Monthly Base Rent and Additional Rent shall be apportioned on a per diem basis and shall be paid to the date of the casualty. In no event shall Landlord be liable to Tenant for any damages resulting to Tenant from the occurrence of
such casualty, or from the repairing or restoration of the Building and Improvements, or from the termination of this Lease as provided herein, nor shall Tenant be relieved thereby from any of Tenant’s obligations hereunder, except to the
extent and upon the conditions expressly set forth in this Paragraph 19. 
 20. Eminent Domain. 

(a) If the whole or any substantial part of the Property is taken or condemned by any competent public authority for any public use or purpose,
the term of this Lease shall end upon the earlier to occur of the date when the possession of the part so taken shall be required for such use or purpose or the vesting of title in such public authority. Rent shall be apportioned as of the date of
such termination. Any award arising from the condemnation of any portion of the Property or the settlement thereof shall belong to and be paid to Landlord. However, Tenant may file a separate claim at Tenant’s sole cost and expense for
(i) leasehold improvements installed at Tenant’s expense or other property owned by Tenant, and (ii) reasonable costs of moving by Tenant to another location in San Mateo County or surrounding areas within the San Francisco Bay Area.
In all events, Landlord shall be solely entitled to any award with respect to the real property, including the bonus value of the leasehold. 

(b) If there is a partial taking of the Property by eminent domain which is not a substantial part of the Property and the Premises remain
reasonably suitable for continued use and occupancy by Tenant for the purposes referred to in Paragraph 7, Landlord shall complete any necessary repairs in a diligent manner and this Lease shall remain in full force and effect with a just and
proportionate abatement of the Monthly Base Rent and Additional Rent, based on the extent to which Tenant’s use of the Premises is completely impaired thereafter. If after a partial taking, the Premises are not reasonably suitable for
Tenant’s continued use and occupancy for the uses permitted herein, Tenant may terminate this Lease effective on the earlier of the date title vests in the public authority or the date possession is taken. Subject to the provisions of Paragraph
20(a), the entire award for such taking shall be the property of Landlord. 
 21. Remedies. If Tenant fails to make any payment of rent or any other
sum due under this Lease for five (5) days after receipt by Tenant of written notice from Landlord; or if Tenant fails to comply with any term, provision or covenant of this Lease and does not cure such failure within fifteen (15) days
after receipt by Tenant of written notice from Landlord or such shorter time period specified in this Lease (unless such default is incapable of cure within fifteen (15) days and Tenant commences cure within fifteen (15) days and
thereafter diligently prosecutes the cure to completion within a reasonable time, not to exceed thirty (30) days); or if Tenant’s interest herein, or any part thereof, is assigned or transferred, either voluntarily or by operation of law
(except as expressly permitted by other provisions of this Lease); or if Tenant makes a general assignment for the benefit of its creditors; or if this Lease is rejected (i) by a bankruptcy trustee for Tenant, (ii) by Tenant as debtor in
possession, or (iii) by failure of Tenant as a bankrupt debtor to act timely in assuming or rejecting this Lease; then any of such events shall constitute an event of default and breach of this Lease by Tenant and Landlord may, at its option,
elect the remedies specified in either subparagraph (a) or (b) below. Any such rejection of this Lease referred to above shall not cause an automatic termination of this Lease. Whenever in this Lease reference is made to a default by Tenant,
such reference shall refer to an event of default as defined in this Paragraph 21.Landlord may repossess the Premises and remove all persons and property therefrom. If Landlord repossesses the Premises because of a breach of this Lease, this Lease
shall terminate and Landlord may recover from Tenant: 

  
 32 












 (1) the worth at the time of award of the unpaid rent which had been earned at the time of
termination including interest thereon at a rate equal to the discount rate established by the Federal Reserve Bank of San Francisco for member banks, plus one percent (1%), or the maximum legal rate of interest, whichever is less, from the time of
termination until paid; 
 (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 rental loss that Tenant proves could have been reasonably avoided, including interest thereon at a rate equal to the Federal discount rate plus one percent (1%) per annum, or the maximum
legal rate of interest, whichever is less, from the time of termination until paid; 
 (3) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award exceeds the amount of such rental loss for the same period that Tenant proves could be reasonably avoided discounted at the discount rate established by the Federal Reserve
Bank of San Francisco for member banks at the time of the award plus one percent (1%); and 
 (4) any other amount necessary to compensate
Landlord for all the detriment proximately caused by Tenant’s breach or 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. 

(c) If Landlord does not repossess the Premises, then this Lease shall continue in effect for so long as Landlord does not terminate
Tenant’s right to possession and Landlord may enforce all of its rights and remedies under this Lease, including the right to recover the rent and other sums due from Tenant hereunder. For the purposes of this Paragraph 21, the following do not
constitute a repossession of the Premises by Landlord or a termination of the Lease by Landlord: 
 (1) Acts of maintenance or preservation
by Landlord or efforts by Landlord to relet the Premises; or 
 (2) The appointment of a receiver by Landlord to protect Landlord’s
interests under this Lease. 

  
 33 












 (d) Landlord’s failure to perform or observe any of its obligations under this Lease or
to correct a breach of any warranty or representation made in this Lease within thirty (30) days after receipt of written notice from Tenant setting forth in reasonable detail the nature and extent of the failure referencing pertinent Lease
provisions or if more than thirty (30) days is required to cure the breach, Landlord’s failure to begin curing within the thirty (30) day period and diligently prosecute the cure to completion, shall constitute a default. If Landlord
commits a default, Tenant’s sole remedy shall be to institute an action against Landlord for damages or for equitable or injunctive relief, but Tenant shall not have the right to punitive damages, consequential damages, rent abatement, offset
against rent, or to terminate this Lease in the event of any default by Landlord. 
 (e) All covenants and agreements to be performed by
Tenant under this Lease shall be at its sole cost and expense and without abatement of rent or other sums due under this Lease, unless otherwise specified in this Lease. If Tenant shall fail to pay any sum of money required to be paid by Tenant
under this Lease or shall fail to perform any other act on Tenant’s part to be performed under this Lease within the time periods described in the first paragraph of Paragraph 21(a), Landlord may, but shall not be obligated so to do and without
waiving or releasing Tenant from any obligations of Tenant, make any such payment or perform any such other act on Tenant’s part to be made or performed as provided in this Lease. All sums paid by Landlord, whether to fulfill Tenant’s
unfulfilled payment obligations, to perform Tenant’s unfulfilled performance obligations, or to compel Tenant to fulfill or perform its obligations under this Lease, and all incidental costs, including attorneys’ fees, plus an
administrative fee of five percent (5%) of all amounts so expended by Landlord, shall be deemed additional rent hereunder and shall be payable to Landlord upon demand. 

22. Tenant’s Personal Property. If any personal property of Tenant remains on the Premises after (1) Landlord terminates this
Lease pursuant to Paragraph 21 above following an event of default by Tenant, or (2) after the expiration of the Lease Term (as may be extended) or after the termination of this Lease pursuant to any other provisions hereof, Landlord shall give
written notice thereof to Tenant pursuant to applicable law. Landlord shall thereafter release, store, and dispose of any such personal property of Tenant in accordance with the provisions of applicable law. 

  
 34

(“Communications”) shall be personally delivered or sent by first class mail, postage prepaid, by overnight courier. In addition, the Landlord may, in its sole discretion, send such Communications to the Tenant electronically, or permit
Tenant to send such Communications to the Landlord electronically, in the manner described in this Paragraph. 

Such Communications sent by personal delivery, mail or overnight courier will be sent to the addresses on the
signature page of this Lease, or to such other addresses as the Landlord and Tenant may specify from time to time in writing. Communications shall be effective (i) if mailed, upon the earlier of receipt or five (5) days after deposit in
the U.S. mail, first class, postage prepaid, or (ii) if hand-delivered, by courier or otherwise (including telegram, lettergram or mailgram), when delivered. 

Such Communications may be sent electronically by the Landlord and Tenant (i) by
transmitting the Communication to the electronic address provided by the Tenant or to such other electronic address as the Tenant may specify from time to time in writing, or (ii) by posting the Communication on a website and sending the Tenant
a notice to the Tenant’s postal address or electronic address telling the Tenant that the Communication has been posted, its location, and providing instructions on how to view it. Communications sent electronically to the Tenant will be
effective when the Communication, or a notice advising of its posting to a website, is sent to the Tenant’s electronic address.

and in the interior of the Building, subject to Landlord’s reasonable requirements and consent and subject to the requirements of the City of Menlo Park. All of Tenant’s signage shall comply with the City of Menlo Park sign ordinances and
regulations and shall be subject to Landlord’s approval as to the specific location, size and design thereof. The cost of the installation of Tenant’s signage on the glass near the front entrance to the Building and within the interior of
the Building shall be paid by Tenant. Any additional signage shall be subject to Landlord’s prior approval and, if approved, shall be installed at Tenant’s expense. 

  
 35 












 26. Real Estate Brokers. Tenant’s broker is Kidder Mathews (“Tenant’s
Broker”) and Landlord’s brokers are Kidder Matthews Newmark Cornish & Carey (“Landlord’s Broker” and collectively with Tenant’s Broker, the “Brokers”). Landlord shall
pay a leasing commission to the Brokers pursuant to a separate agreement. Each party represents and warrants to the other party that it has not had any dealings with any real estate broker, finder, or other person with respect to this Lease other
than the Brokers and each party shall hold harmless the other party from all damages, expenses, and liabilities resulting from any claims that may be asserted against the other party by any broker, finder, or other person with whom the other party
has or purportedly has dealt, other than the Brokers. 
 27. Parking. Tenant shall have the right to the nonexclusive use of nineteen
(19) unreserved on-site vehicular parking spaces on the Land at no additional cost to Tenant in the parking area for the Building or nearby parking areas in Menlo Business Park, provided that if the City
of Menlo Park requires that the number of striped parking spaces located at the Building to be reduced to conform to maximum parking allowances adopted by the City of Menlo, and so long as such requirement was not triggered by Landlord, the number
of parking spaces identified in the first sentence of this Paragraph 27 shall be proportionately reduced. Parking shall be subject to such rules and regulations for such parking facilities which may be established or altered by Landlord at any time
from time to time during the Lease Term (as may be extended), provided that such rules and regulations shall not unreasonably interfere with Tenant’s parking rights. Vehicles of Tenant or its employees shall not park in driveways or occupy
parking spaces or other areas reserved for deliveries, or loading or unloading. 
 28. Subordination; Attornment. 

(a) This Lease, without any further instrument, shall at all times be subject and subordinate to the lien of any and all mortgages and deeds of
trust which may now or hereafter be placed on, against or affect Landlord’s estate in the real property of which the Premises form a part, and to all advances made or hereafter to be made upon the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Notwithstanding anything to the contrary in this Paragraph 28, at Tenant’s request, Landlord hereby agrees to use commercially reasonable efforts to obtain from its current
mortgagee a subordination and non-disturbance and attornment agreement (“SNDA”) in substantially the form attached hereto as Exhibit “I” and made a part hereof, or in any other
commercially reasonable form provided by any future mortgagee. Tenant is required to pay a lender fee of $1,500.00 for any such SNDA. If Tenant chooses to negotiate the language of the SNDA, additional fees may apply. 

(b) In confirmation of such subordination, Tenant covenants and agrees to execute and deliver within ten (10) days of Landlord’s
request any certificate or other instrument which Landlord may reasonably deem proper to evidence such subordination in commercially reasonable form (which document recognizes Tenant’s rights under this Lease), without expense to Tenant;
provided, however, that if any person or persons purchasing or otherwise acquiring the real property of which the Premises form a part by any sale, sales and/or other proceedings under such mortgages and/or deeds of trust, shall elect to continue
this Lease in full force and effect in the same manner and with like effect as if such person or persons had been named as Landlord herein, then this Lease shall continue in full force and effect as aforesaid, and Tenant hereby attorns and agrees to
attorn to such person or persons in writing upon request. 

  
 36 












 (c) If Tenant is notified in writing of Landlord’s default under any deed of trust
affecting the Premises and if Tenant is instructed in writing by the party giving notice to make Tenant’s rental payments to such beneficiary, Tenant shall comply with such request without liability to Landlord (and with full credit of any
amounts paid to such party by Tenant to the corresponding amounts owed to Landlord) until Tenant receives written confirmation that such default has been cured by Landlord and that the deed of trust has been reinstated. 

29. No Termination Right. Tenant shall not have the right to terminate this Lease as a result of any default by Landlord, and Tenant’s remedies in
the event of a default by Landlord shall be limited to the remedy set forth in Paragraph 21(c). Tenant expressly waives the defense of constructive eviction. 

30. Landlord’s Entry. Except in the case of an emergency, which may occur without prior notice to Tenant, Landlord and
Landlord’s agents shall provide Tenant with at least twenty-four (24) hours’ notice prior to entry of the Premises. Provided Tenant makes a representative available by the end of the applicable notice period provided for above and
excluding any entry in the event of an emergency, Tenant may request that Landlord or any representative of Landlord entering the Premises pursuant to the provisions of this Paragraph 30, be accompanied at all times by a representative of Tenant.
Landlord may enter the Premises for any reasonable purpose related to Landlord’s ownership and operation of the Property. Such entry by Landlord and Landlord’s agents shall not impair Tenant’s operations more than reasonably
necessary. Landlord may enter the Premises at any time without prior notice to Tenant if the Premises are vacant, if Tenant is no longer conducting its ordinary business at the Premises, or if Tenant has made a general assignment for the benefit of
creditors. 
 31. Attorneys’ Fees. If any action at law or in equity shall be brought to recover any rent under this Lease, or for
or on account of any breach of or to enforce or interpret any of the provisions of this Lease or for recovery of the possession of the Premises (including litigation, or a proceeding in a bankruptcy court), the prevailing party shall be entitled to
recover from the other party costs of suit and reasonable attorneys’ fees, the amount of which shall be fixed by the court and shall be made a part of any judgment rendered. 

32. Quiet Enjoyment. Upon payment by Tenant of the rent for the Premises and the observance and performance of all of the covenants, conditions, and
provisions on Tenant’s part to be observed and performed under this Lease within applicable notice and cure periods, Tenant shall have quiet enjoyment and possession of the Premises for the entire term hereof subject to all of the provisions of
this Lease. 
 33. Financial Information. Tenant represents and warrants to Landlord that all financial and other information that it has provided to
Landlord prior to the date of this Lease is true, correct and complete. 
 34. SDN List. Tenant represents and warrants to Landlord that Tenant is
not, and the entities or individuals that constitute Tenant, that may own or control Tenant, or that may be owned or controlled by Tenant (in all cases, other than through the ownership of publicly traded, direct or indirect ownership interests)
(each a “Subject Tenant Party”) are not, (i) in violation of any laws relating to terrorism or money laundering, or (ii) among the individuals or entities identified on any list compiled pursuant to Executive Order 13224 or
published by the Office of Foreign Assets Control, U.S. Department of the Treasury (“OFAC”) for the purpose of identifying suspected terrorists or on the most current list published by the OFAC at its official website,
http://www.treas.gov/ofac/tllsdn.pdf or any replacement website or other replacement official publication of such list which identifies an “Specially Designated National” or “blocked person” (either of which are referred to
herein as a “SDN”). If at any time during the Lease Term (as may be extended) Landlord discovers that Tenant has breached the foregoing representations and warranties, or Landlord reasonably believes that Tenant or any Subject Tenant Party
is in violation of any laws relating to terrorism or money laundering or that Tenant or any Subject Tenant Party is identified as an SDN, Tenant shall be deemed in default under this Lease following three (3) days written notice from Landlord
to Tenant unless, within such three day period, Tenant delivers written evidence, reasonably acceptable to Landlord, that Tenant is not in violation of such laws or that Tenant (or the Subject Tenant Party, as applicable) is not a person or entity
identified as an SDN. Except as otherwise expressly provided in the foregoing sentence, and without further notice, any default by Tenant under this Paragraph 34 shall be deemed an incurable default by Tenant and, in addition to any other rights and
remedies that Landlord may have upon such default, Landlord shall also have the right to immediately terminate this Lease upon written notice to Tenant and recover possession of the Premises. 

  
 37 












 35. Sustainable Practices for the Building. Landlord and Tenant acknowledge and agree that Landlord
is committed to employing sustainable operating and maintenance practices for the Building. Tenant shall fully cooperate with Landlord in any programs in which Landlord may elect to participate relating to the Building’s (i) energy
efficiency, management and conservation; (ii) water conservation and management; (iii) environmental standards and efficiency; (iv) recycling and reduction programs; and/or (v) safety, which participation may include, without
limitation, the Leadership in Energy and Environmental Design (LEED) program and related Green Building Rating System promoted by the U.S. Green Building Council. All carbon tax credits and similar credits, offsets and deductions are the sole and
exclusive property of Landlord. Tenant affirms its support of these practices, and agrees to cooperate with Landlord by implementing reasonable conservation practices. Periodically, Landlord may offer additional examples, guidance and practices
related to energy conservation measures, which Tenant agrees to consider for implementation. Notwithstanding anything herein to the contrary, Tenant shall not be restricted from operating its business in the fashion and manner which it deems
appropriate for itself, in accordance with the Use provisions of this Lease. Should any specific practice(s) proposed by Landlord be deemed to be inconsistent with Tenant’s business operations, Tenant shall so advise Landlord in writing as its
reason for declining to implement such specific practice(s). 
 36. Tenant Amenities. During the Term of this Lease (as may be extended), Tenant shall
have the right to use, in common with Landlord, its employees, tenants and invitees, certain shared amenities of the Property which include the Gym (including the pool located at the Gym), Restaurant and the Event Room and Conference Room located at
1430/1440 O’Brien Drive, Menlo Park, California together with the Sports Courts (which consist of the volleyball, basketball and tennis courts) located immediately adjacent to the building located at 1505 O’Brien Drive, Menlo Park,
California (the “Shared Amenities”). Tenant’s use of the Shared Amenities shall be subject to such rules and regulations as Landlord may reasonably prescribe from time to time upon notice to Tenant and shall be without any additional
charge or cost therefore other than with respect to all food and beverages consumed within the Restaurant or any classes or personal training, individual services or separately or additionally charged services offered at the Gym. Landlord reserves
the right to make all such changes, additions, improvements and replacements to the Shared Amenities as Landlord may elect, in its sole and absolute discretion, and nothing set forth herein in this Paragraph 36 shall be deemed a covenant or
representation that Landlord shall offer the Shared Amenities during certain hours nor shall it be deemed a covenant or representation that Landlord shall not cease operation of (i.e., entirely shut down) all, or a portion of, the Shared Amenities
during the Term (as may be extended). In addition, in Landlord’s sole and absolute discretion, Tenant may, without any additional cost therefore, reserve and utilize such Event Room and Conference Room on an
as-available basis. Tenant must use Landlord’s reservation system for its use of the Event Room and Conference Room. Notwithstanding the foregoing or anything to the contrary contained herein, under no
circumstances shall the Shared Amenities be deemed to be a part of the Common Area square footage allocations for the purposes of this Lease; provided, however the foregoing shall not prohibit Landlord from including in Park Expenses the costs
associated with the Shared Amenities in accordance with Section 4 above. 

  
 38 












 37. Emergency Generator. Subject to the waivers of liability as set forth in the Paragraph 14 in
connection with the occurrence of any utility service interruptions, Landlord shall connect the Premises to the existing back-up generator servicing the Property and owned, operated and maintained by Landlord.
During the Term of this Lease (as may be extended), Landlord shall use its commercially reasonable efforts to keep such back-up generator in good condition and repair, shall provide for periodic maintenance
and repair in accordance with manufacturer’s recommendations and shall cause sufficient quantities of fuel to be present in the storage tank servicing such back-up generator; provided that Tenant
acknowledges and agrees that Landlord makes no representations, warranties or guarantees concerning the performance of such back-up generator and Tenant further understands and acknowledges that upon the
occurrence of a force majeure delay causing a disruption in the electrical service to the Property, Landlord may be unable to obtain sufficient quantities of fuel necessary to allow the back-up generator to
provide uninterrupted electrical service to such data and telephone systems upon such inability to refuel the Property’s storage tanks. 
 38.
General Provisions

create the relationship of principal and agent or of partnership or of joint venture of any association between Landlord and Tenant, and neither the method of computation of rent nor any other provisions contained in this Lease nor any acts of the
parties hereto shall be deemed to create any relationship between Landlord and Tenant other than the relationship of landlord and tenant.

specifically provided elsewhere in this Lease, their respective heirs, executors, administrators, successors, and assigns, subject at all times, nevertheless, to all agreements and restrictions contained elsewhere in this Lease with respect to the

signed by the parties hereto and has been rendered tamper-evident as part of the signing process. The exchange of email or other electronic communications discussing an amendment to this Lease, even if such communications are signed, does not
constitute a signed electronic record agreeing to such an amendment.

Lease on its behalf is properly authorized to do so, and in the event this Lease is signed by an agent or other third party on behalf of either Landlord or Tenant, written authority to sign on behalf of such party in favor of the agent or third
party shall be provided to the other party hereto either prior to or simultaneously with the return to such other party of a fully executed copy of this Lease.

Landlord, and ZAI LAB (US), LLC, a Delaware limited liability company, as Tenant, concerning the Premises consisting of approximately 18,707 rentable square feet in the building commonly known as 1440 O’Brien Drive, Suites A& C, Menlo Park,
California. 
 In consideration of the mutual covenants contained below, Landlord and Tenant agree as follows: 

1. Definitions. For purposes of this Work Letter, (i) capitalized terms not defined in this Work Letter but defined in the Lease shall have the
same meaning ascribed to such terms in the Lease and (ii) other terms used in this Work Letter shall have the meaning ascribed to such term as set forth in this paragraph 1 or elsewhere in this Work Letter. 

a. “Tenant Improvements” shall mean the work and improvements to be performed by Landlord as shown on the Construction Drawings. All
such work shall be performed by Landlord at Tenant’s sole cost and expense, subject to reimbursement in the amount of the Tenant Improvement Allowance (as hereinafter defined). 

b. “Construction Drawings” shall mean the approved plans and specifications for the Tenant Improvements (“Plans”). 

c. [Intentionally omitted.] 
 d.
“Substantially Completed” or “Substantial Completion” shall mean Landlord has completed the Tenant Improvements subject only to items which need correction or completion and are of a nature and degree as to typically appear on a
construction project punch list (“Punch List Items”) and to a state of completion to allow Tenant to have unhindered access to the Premises to install its trade fixtures, furniture, equipment, cabling, telecommunications and similar
alterations within the Premises, which installation shall be Tenant’s responsibility, at Tenant’s cost. Within five (5) business days after Substantial Completion, Landlord and Tenant shall perform a joint walk-through of the Premises
and mutually and reasonably identify in a written statement executed by each of them (“Punch List”) the remaining Punch List Items. Landlord shall cause the Punch List Items to be corrected or completed as soon as reasonably possible. 

2. Landlord’s Work. Except as provided in this Work Letter, the Premises shall be delivered to Tenant in its
AS-IS condition. Landlord shall, at Landlord’s cost deliver the Building in “warm shell condition” (collectively, “Landlord’s Work”). “Warm shell condition” shall mean:

 3. Design Process/Working Drawings 

a. Architect and Contractor. Upon execution of the Lease, Landlord will retain the services of an architect (“Architect”) and a
licensed general contractor (the “Contractor”) to build the Tenant Improvements in accordance with the Budget and the Construction Drawings. 

b. Submission of Plans and Specifications. Landlord shall work with the Architect for the purpose of creating construction drawings and
specifications for the Tenant Improvements. Tenant shall advise Landlord within five (5) days of receipt of Landlord’s proposed construction drawings and specifications under this Work Letter whether Tenant approves or disapproves such
construction drawings and specifications. If Tenant reasonably disapproves Landlord’s construction drawings and specifications, or any portion thereof, Tenant shall, within a reasonable time, but in any event within the five (5) days,
notify Landlord thereof and of the revisions which Tenant reasonably requires in order to obtain Tenant’s reasonable approval. If Tenant does not advise Landlord within such five (5) day period of its disapproval setting forth the basis of
such disapproval in reasonable detail, such approval shall be deemed granted. As promptly as reasonably possible thereafter, Landlord shall request the Architect to submit to Tenant construction drawings and specifications incorporating the
revisions reasonably requested by Tenant. All such revisions shall be subject to Tenant’s and Landlord’s approval (which shall not be unreasonably withheld) and such consent shall be withheld or granted by Tenant or Landlord (as the case
may be) within five (5) days. If Tenant does not advise Landlord within such five (5) day period of its disapproval of the revisions, such approval shall be deemed granted. This process shall be repeated until Landlord and Tenant
reasonably approve the constructing drawings and specifications. Notwithstanding the foregoing, if Landlord and Tenant are unable to approve the construction drawings and specifications on or before September 30, 2019, Landlord’s last
version of such construction drawings and specifications shall be deemed approved. The final approved, or deemed approved, construction drawings and specifications shall be referred to as the “Plans”. 

c. Budget. Landlord shall work with the Architect and Contractor for the purpose of creating a budget or the Tenant Improvements. Tenant shall
advise Landlord within five (5) days of receipt of Landlord’s proposed budget under this Work Letter whether Tenant approves or disapproves such budget. If Tenant reasonably disapproves Landlord’s budget, or any portion thereof,
Tenant shall, within a reasonable time, but in any event within the five (5) days, notify Landlord thereof and of the revisions which Tenant reasonably requires in order to obtain Tenant’s reasonable approval. If Tenant does not advise
Landlord within such five (5) day period of its disapproval setting forth the basis of such disapproval in reasonable detail, such approval shall be deemed granted. As promptly as reasonably possible thereafter, Landlord shall revise the Budget
incorporating the revisions reasonably requested by Tenant. All such revisions shall be subject to Tenant’s and Landlord’s approval (which shall not be unreasonably withheld) and such consent shall be withheld or granted by Tenant or
Landlord (as the case may be) within five (5) days. If Tenant does not advise Landlord within such five (5) day period of its disapproval of the revisions, such approval shall be deemed granted. This process shall be repeated until
Landlord and Tenant reasonably approve the budget. Notwithstanding the forgoing, if Landlord and Tenant are unable to approve the budget on or before September 30, 2019, Landlord’s last version of such budget shall be deemed approved. The
final approved, or deemed approved, budget shall be referred to as the “Budget”. 

  
 EXHIBIT “G”













 d. Commencement of Construction. At such time as all necessary governmental permits and
other required approvals have been obtained by Landlord, Landlord shall commence construction of and, once commenced, shall diligently pursue the completion of the Tenant Improvements substantially in compliance with the Construction Drawings, the
Budget and this Work Letter. 
 4. Tenant Improvement Allowance. 

a. Provided that Tenant is not in default under the Lease or this Work Letter (following the expiration of all applicable notice and cure
periods without cure), Landlord shall contribute $125/psf or Two Million Three Hundred Thirty-Eight Thousand Three Hundred Seventy-Five and 00/100ths Dollars ($2,338,375.00) (the “Tenant Improvement Allowance”) as set forth herein toward
the cost of the Tenant Improvements. The Tenant Improvement Allowance shall be used to pay for the cost of (i) the Construction Drawings for the Tenant Improvements within the Premises, (ii) engineering required in connection with the
performance of such work, (iii) all permit fees required by any administrative or governmental agency in connection with the performance of the Tenant Improvements or other costs expended in obtaining approvals and permits, (iv) actual
contractor costs and charges for materials, supplies and labor, contractor’s profit, overhead and general conditions, (v) any other costs incurred in connection with the hard and soft costs of construction of the Tenant Improvements;
provided, however, that no portion of the Tenant Improvement Allowance shall be used to pay for furniture, moving or Tenant’s trade fixtures, furniture, furnishings or equipment. Tenant shall be solely responsible for all costs of Tenant
Improvements in excess of the Tenant Improvement Allowance (“Excess TI Costs”). Until the Budget is approved, Landlord shall pay all invoices coming due before the Budget is approved in connection with the Tenant Improvements
(“Interim Construction Payments”). Once the Budget is approved, Tenant shall reimburse Landlord its proportionate share (in the proportion of the Excess TI Costs payable by Tenant to the Tenant Improvement Allowance payable by Landlord) of
the Interim Construction Payments on a pari passu basis within fifteen (15) days of the first invoicing by Landlord, and thereafter, Tenant shall pay its proportion of the Excess TI Costs payable by Tenant to the Tenant Improvement Allowance
payable by Landlord on a pari passu basis with Landlord as the costs become due, within fifteen (15) days of invoicing by Landlord. For clarity, Landlord shall not be required to pay any costs of the Tenant Improvements in excess of the Tenant
Improvement Allowance and Tenant shall pay any costs of the Tenant Improvements in excess of the Tenant Improvement Allowance (once such Tenant Improvement Allowance is exhausted as set forth herein) within ten (10) days after written demand by
Landlord accompanied by supporting materials including invoices. 
 5. Consents/Approvals/Representatives. Landlord has appointed Ron Krietemeyer, as
its authorized representative (“Landlord’s Representative”) to act for Landlord in all matters covered by this Work Letter. Tenant hereby designates Peter Brams, as its authorized representative (“Tenant’s
Representative”) with full power and authority to bind Tenant for all actions taken with regard to the Tenant Improvements. Except as otherwise provided in this Work Letter, within three (3) Business Days of receipt of any requested
approval of any item or document, Landlord’s Representative shall approve or disapprove (with sufficient detail) any such request, unless the scope of Tenant’s request is such that Landlord’s Representative cannot, using commercially
reasonable efforts, complete the required modifications within three (3) Business Days, in which case such three (3) Business Day period shall be extended for such period after Landlord receives the request as is reasonably necessary to
respond to such request. 

  
 EXHIBIT “G”













 6. Construction Management Fee. Landlord shall employ Tarlton Properties, Inc. as the construction
manager for construction of the Tenant Improvements at a fee equal to four percent (4%) of hard construction costs (i.e., amounts paid to any general contractor, subcontractors, vendors and suppliers of labor and materials for the construction of
the Tenant Improvements). Such construction management fee shall be a cost of the Tenant Improvements. 
 7. Miscellaneous. Tenant shall not be
required to post any bond or other security for the performance of Tenant’s Improvements performed pursuant to this Work Letter. In the event of a conflict between the Lease (including the Work Letter) and the Construction Drawings, the
Construction Drawings shall control. 
 8. Construction of the Tenant Improvements. All materials (as well as methods and processes) used in the
performance of the Tenant Improvements shall be new and of good quality and conform to all reasonable standards of the Building. All of the Tenant Improvements shall be performed in a good and workmanlike manner and in accordance with any and all
applicable codes, statutes, rules, regulations, ordinances and orders of any federal, state, county or municipal agency or other governmental body having jurisdiction over the Premises, and in substantial compliance with the Construction Drawings
and Budget. 
 9. Tenant Delays. Any delay directly related to or arising from any interference by Tenant or its employees, agents or contractors
with Landlord’s completion of the Tenant Improvement, or any default by Tenant under the Lease or failure to comply with the terms of this Work Letter which causes delay in construction of the Tenant Improvements shall constitute a “Tenant
Delay”. Landlord shall give Tenant written notice of any claimed Tenant Delay within four (4) business days after the beginning of the delay, which notice includes a specific description of the claimed Tenant Delay. Should a Tenant Delay
occur, Landlord shall not be responsible for such Tenant Delay, including without limitation, increased construction costs, increased general condition costs and other costs, the construction schedule and Tenant’s ability to conduct business or
occupy the Premises. 
 10. Tenant Default. If Tenant is in default of the Lease (following the expiration of all applicable notice and cure periods
without cure), at any time on or before the Substantial Completion of the Tenant Improvements, then in addition to all other rights and remedies granted to Landlord under the Lease, Landlord shall have the right to immediately cease all construction
of the Tenant Improvements and all other obligations of Landlord under this Work Letter shall be suspended until such time as such default is cured pursuant to the terms of the Lease.

Form of Non-Disturbance and Attornment Agreement

ATTN: Jill Lauckner 
 NON-DISTURBANCE 
 AND ATTORNMENT AGREEMENT 

Loan 757406 
 THIS AGREEMENT, made
and entered into as of the _____ day of ______________, 2019, by and between PRINCIPAL LIFE INSURANCE COMPANY, an Iowa corporation, with an address for purposes of notice at c/o Principal Real Estate Investors, LLC, 801 Grand Avenue, Des Moines,
Iowa 50392-1450 (hereinafter called “Lender”) and ________________________________________________________________________ with its principal office at ________________________________________________________________ (hereinafter called
“Lessee”); 
 WITNESSETH: 

WHEREAS, Lessee has by a written lease dated _______________, as amended by ______________________________ (hereinafter called the
“Lease” and the definition of “Lease” shall also include any future amendments or modifications specifically approved in writing by Lender), leased from the landlord named in the Lease (hereinafter called “Lessor”), all
or part of certain real estate and improvements thereon located at ________________________________________, as more particularly described in Exhibit A attached hereto (the “Demised Premises”); and 

WHEREAS, Lessor is encumbering (or has previously encumbered) the Demised Premises as security for a loan (the “Loan”) from Lender
to Lessor (the “Mortgage”); and 
 WHEREAS, Lessee and Lender have agreed to the following with respect to their mutual rights and
obligations pursuant to the Lease and the Mortgage; 
 NOW, THEREFORE, for and in consideration of Ten Dollars ($10.00) paid by each party
to the other and the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt whereof is hereby acknowledged, the parties hereto do hereby covenant and agree as follows: 

  
 EXHIBIT “I”













 (1) In the event of any foreclosure of the Mortgage or any conveyance in lieu of
foreclosure, provided that the Lessee shall not then be in default beyond any grace period under the Lease and that the Lease shall then be in full force and effect, then Lender shall neither terminate the Lease nor join Lessee in foreclosure
proceedings, nor disturb Lessee’s possession, and the Lease shall continue in full force and effect as a direct lease between Lessee and Lender. Lender further agrees not to join Lessee in any foreclosure proceeding except to the extent
necessary under applicable law, but such joinder shall not be in derogation of the rights of Lessee as set forth in this Agreement. 
 (2)
After the receipt by Lessee of notice from Lender of any foreclosure of the Mortgage or any conveyance of the Demised Premises in lieu of foreclosure, Lessee will thereafter attorn to and recognize Lender or any purchaser at any foreclosure sale or
otherwise as its substitute lessor on the terms and conditions set forth in the Lease. 
 (3) Lessee hereby agrees that if Lessee has the
right to terminate the Lease or to claim a partial or total eviction, or to abate or reduce rent due to a Lessor default under the Lease, Lessee will not exercise such right until it has given written notice to Lender, and Lender has failed within
thirty (30) days after both receipt of such notice and the date when it shall have become entitled to remedy the same, to commence to cure such default and thereafter diligently prosecute such cure to completion within ninety (90) days of
Lender’s commencement to cure such default. 
 (4) Lessee agrees that if the Lease is terminated pursuant to the terms of the Lease, or
otherwise, Lessee will remit any payments made in connection with such termination directly and immediately to Lender. 
 (5) In no event
shall Lender be liable for: (a) the return of any security deposit provided to Lessor under the Lease unless said security deposit is actually received by Lender and then only pursuant to the terms of the Lease; (b) any act or omission of
the Lessor; (c) any covenant of Lessor to undertake or complete the initial construction or installation of improvements on the Demised Premises; (d) any sums due Lessee under the Lease related to the costs of preparing, furnishing or
moving into the Demised Premises (for example, a construction or tenant improvement allowance); or (e) any covenant of Lessor related to restrictive uses or exclusives which pertain to properties outside of the Demised Premises and which Lender
could not reasonably comply with if it became Lessor under the Lease. Further, Lender shall not be subject to any offsets or deficiencies which Lessee may be entitled to assert against the Lessor as a result of any act or omission of Lessor
occurring prior to Lender’s obtaining title to the Demised Premises, it being understood that nothing in this clause shall be deemed to exclude Lender from responsibility for repairs and maintenance required of the Lessor under the Lease from
and after the date Lender takes title to the Demised Premises, whether or not the need for such repairs or maintenance accrued before or after such date; provided, however, that in no event shall Lender be responsible for consequential damages
resulting from the failure of Lessor to undertake such repairs and maintenance. 
 (6) This Agreement and its terms shall be governed by the
laws of the state where the Demised Premises are located and shall be binding upon and inure to the benefit of Lender and Lessee and their respective successors and assigns, including, without limitation, any purchaser at any foreclosure sale or
otherwise. This Agreement may not be modified orally or in any manner other than by an agreement, in writing, signed by the parties. 

  
 EXHIBIT “I”













 (7) This Agreement may be executed in counterparts, each of which shall be deemed to be an
original, and such counterparts when taken together shall constitute but one agreement. 
 IN WITNESS WHEREOF, this Agreement has been fully
executed on the day and year first above written.
