 Exhibit 10.9 

TP THERAPEUTICS, INC. 

EXECUTIVE EMPLOYMENT AGREEMENT 

for 
 YISHAN (PETER) LI,
PH.D., M.B.A. 
 This Executive Employment Agreement (this “Agreement”), is made and entered into
effective as of September 29, 2018 (the “Effective Date”), by and between Yishan (Peter) Li (“Executive”) and TP Therapeutics, Inc. (the “Company”). 

WHEREAS, the Company and Executive desire to enter into an agreement of employment on the
terms set forth herein. 
 NOW, THEREFORE, in consideration of the
mutual promises and covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows: 

1.    Employment by the Company. 

1.1    Position. Executive shall serve as the Company’s Head of TP Therapeutics, Asia,
reporting to the Company’s Board of Directors (the “Board”). Executive shall continue to serve as a member of the Board. During the term of Executive’s employment with the Company, Executive will devote Executive’s
best efforts and substantially all of Executive’s business time and attention to the business of the Company, except for approved vacation periods and reasonable periods of illness or other incapacities permitted by the Company’s general
employment policies. 
 1.2    Duties and Location. Executive shall perform such duties as
are customarily associated with the position of Head of TP China/Asia and such other duties as are assigned to Executive by the Board. Executive’s primary office location shall be the Company’s headquarters located in San Diego,
California. Subject to the terms of this Agreement, the Board reserves the right to reasonably require Executive to perform Executive’s duties at places other than Executive’s primary office location from time to time and to require
reasonable business travel. 
 1.3    Policies and Procedures. The employment relationship
between the parties shall be governed by the general employment policies and practices of the Company, except that when the terms of this Agreement differ from or are in conflict with the Company’s general employment policies or practices, this
Agreement shall control. 
 2.    Compensation. 

2.1    Base Salary. For services to be rendered hereunder, Executive shall receive a base
salary at the rate of $26,666.66 per month, which equates to $320,000 per year (the “Base Salary”), less standard payroll deductions and withholdings and payable in accordance with the Company’s regular payroll schedule. 

  
 1. 

 2.2    Annual Bonus. Executive will be
eligible for an annual discretionary bonus (the “Annual Bonus”) of up to 40% of Executive’s then current annual Base Salary (the “Target Bonus Amount”). Whether Executive receives an Annual Bonus for any given
year, and the amount of any such Annual Bonus, will be determined in the good faith discretion of the Board (or the Compensation Committee thereof), based upon the Company’s and Executive’s achievement of objectives and milestones to be
determined on an annual basis by the Board (or Compensation Committee thereof). No Annual Bonus is guaranteed and, in addition to the other conditions for earning such compensation, Executive must remain an employee in good standing of the Company
on the scheduled Annual Bonus payment date in order to be eligible for any Annual Bonus. 

3.    Standard Company Benefits. Executive shall, in accordance with Company policy and the
terms and conditions of the applicable Company benefit plan documents, be eligible to participate in the benefit and fringe benefit programs provided by the Company to its executive officers and other employees from time to time. Any such benefits
shall be subject to the terms and conditions of the governing benefit plans and policies and may be changed by the Company in its discretion. Executive shall be entitled to five weeks of paid time off per year. 

4.    Expenses. The Company will reimburse Executive for reasonable travel, entertainment or
other expenses incurred by Executive in furtherance or in connection with the performance of Executive’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time. 

5.    Equity. 

5.1    Current Option. Executive acknowledges that Executive has received prior stock
options covering 60,000 shares of the Company’s common stock (the “Existing Options”). The Existing Options were granted under our 2013 Equity Incentive Plan (the “2013 Plan”) and standard form of option
agreement thereunder. Except as otherwise provided in this Agreement, the Existing Options shall continue to be governed in all respects by the terms of the applicable equity award documents. 

5.2    Additional Option.    Subject to approval by the Board,
Executive will be granted an additional stock option covering a number of shares of the Company’s common stock which, when added to the shares covered by the Existing Options, represents approximately 1.0% of the current fully-diluted
capitalization of the Company. 
 5.3    Anti-Dilution Option. In the event, prior to the
earliest of (i) December 31, 2019, (ii) the date, if any, on which the Company completes a public offering of its Common Stock or (iii) the effective date of a Change in Control (as defined in the 2013 Plan), if any, Executive’s
equity holdings in the Company no longer represent at least 1.0% of the Company’s fully-diluted outstanding capitalization (the “Ownership Threshold”) as a result of subsequent equity financings or stock issuances by the
Company (an “Equity Event”), then as soon as reasonably practicable after the occurrence of an Equity Event that causes Executive’s equity holdings to decrease below the Ownership Threshold, subject to the approval of the Board
or its Compensation Committee, which approval will be obtained within five days of the date on which an Equity Event occurs, Executive will be granted an option to purchase a number of shares of 

  
 2. 

 
the Company’s Common Stock in an amount that will cause Executive’s equity holdings in the Company after the option is granted to represent 1.0% of the Company’s fully-diluted
outstanding capitalization (an “Anti-Dilution Option”). The exercise price per share of an Anti-Dilution Option will be determined by the Board or the Compensation Committee when the Anti-Dilution Option is granted and will equal
the fair market value of the Company’s Common Stock as of that date. Subject to any accelerated vesting provisions applicable to Executive, and further subject to Executive’s continuous service with the Company through such vesting dates,
Executive will vest in 1/48th of the Anti-Dilution Option shares after each month after the Effective Date of this Agreement. For the avoidance of doubt, over the period of Executive’s service, more than one Anti-Dilution Option may be granted
to Executive as set forth in this paragraph. The Anti-Dilution Option will be granted under our 2013 Plan and standard form of option agreement thereunder. 

6.    Proprietary Information Obligations. 

6.1    Proprietary Information Agreement. Executive acknowledges that Executive executed,
and will continue to abide by, the Company’s standard Proprietary Information and Inventions Agreement (“Proprietary Agreement”). 

6.2    Third-Party Agreements and Information. Executive represents and warrants that
Executive’s employment by the Company does not conflict with any prior employment or consulting agreement or other agreement with any third party, and that Executive will perform Executive’s duties to the Company without violating any such
agreement. Executive represents and warrants that Executive does not possess confidential information arising out of prior employment, consulting, or other third party relationships, that would be used in connection with Executive’s employment
by the Company, except as expressly authorized by that third party. During Executive’s employment by the Company, Executive will use in the performance of Executive’s duties only information that is generally known and used by persons with
training and experience comparable to Executive’s own, common knowledge in the industry, otherwise legally in the public domain, or obtained or developed by the Company or by Executive in the course of Executive’s work for the Company.

 7.    Outside Activities and Non-Competition During
Employment. 
 7.1    Outside Activities. Throughout Executive’s employment with
the Company, Executive may engage in civic and not-for-profit activities so long as such activities do not interfere with the performance of Executive’s duties
hereunder or present a conflict of interest with the Company or its affiliates. Subject to the restrictions set forth herein, and only with prior written disclosure to and consent of the Board, Executive may engage in other types of business or
public activities. The Board may rescind such consent, if the Board determines, in its sole discretion, that such activities compromise or threaten to compromise the Company’s or its affiliates’ business interests or conflict with
Executive’s duties to the Company or its affiliates. 
 7.2    Non-Competition During Employment. Except as otherwise provided in this Agreement, during Executive’s employment by the Company, Executive will not, without the express written consent of the Board,
directly or indirectly serve as an officer, director, stockholder, employee, partner, proprietor, investor, joint ventures, associate, representative or 

  
 3. 

 
consultant of any person or entity engaged in, or planning or preparing to engage in, business activity competitive with any line of business engaged in (or planned to be engaged in) by the
Company or its affiliates; provided, however, that Executive may purchase or otherwise acquire up to (but not more than) 1% of any class of securities of any enterprise (without participating in the activities of such enterprise) if such securities
are listed on any national or regional securities exchange. In addition, Executive will be subject to certain restrictions (including restrictions continuing after Executive’s employment ends) under the terms of the Proprietary Agreement. 

8.    Termination of Employment; Severance and Change in Control Benefits. 

8.1    At-Will Employment. Executive’s
employment relationship is at-will. Either Executive or the Company may terminate the employment relationship at any time, with or without Cause (as defined below) or advance notice. 

8.2    Covered Termination Unrelated to Change in Control. In the event Executive’s
employment with the Company is terminated due to a Covered Termination (as such term is defined in the Company’s Severance Benefit Plan, as amended (the “Severance Plan”)) at any time except during the Change in Control Period
(as defined in the Severance Plan), then Executive shall be entitled to the benefits provided under, and subject to the terms and conditions of, the Severance Plan; provided that Executive’s Severance Period (as defined in the Severance Plan)
under the Severance Plan shall not be less than 12 months. 
 8.3    Covered Termination
During Change in Control Period. In the event Executive’s employment with the Company is terminated due to a Covered Termination, then in lieu of (and not additional to) the Severance Benefits described in Section 8.2, Executive shall
be entitled to the benefits provided under, and subject to the terms and conditions of, the Severance Plan; provided that Executive’s Severance Period (as defined in the Severance Plan) under the Severance Plan shall not be less than 18 months.

 8.4    Termination for Cause; Death or Disability. Executive will not be eligible for,
or entitled to any severance benefits, including (without limitation) the Severance Benefits and Change in Control Benefits listed in Sections 8.2 and 8.3 above, if the Company terminates Executive’s employment for Cause, or Executive’s
employment terminates due to Executive’s death or disability. 
 9.    Dispute
Resolution. To ensure the rapid and economical resolution of disputes that may arise in connection with Executive’s employment with the Company, Executive and the Company agree that any and all disputes, claims, or causes of action, in law
or equity, including but not limited to statutory claims, arising from or relating to the enforcement, breach, performance, or interpretation of this Agreement, Executive’s employment with the Company, or the termination of Executive’s
employment from the Company, will be resolved pursuant to the Federal Arbitration Act, 9 U.S.C. §1-16, and to the fullest extent permitted by law, by final, binding and confidential arbitration conducted
in San Diego, California by JAMS, Inc. (“JAMS”) or its successors, under JAMS’ then applicable rules and procedures for employment disputes (which can be found at http://www.jamsadr.com/rules-clauses/, and which will be
provided to Executive on request); provided that the arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would 

  
 4. 

 
otherwise be permitted by law; and (b) issue a written arbitration decision including the arbitrator’s essential findings and conclusions and a statement of the award. Executive and the
Company shall be entitled to all rights and remedies that either would be entitled to pursue in a court of law. Both Executive and the Company acknowledge that by agreeing to this arbitration procedure, they waive the right to resolve any such
dispute through a trial by jury or judge or administrative proceeding. The Company shall pay all filing fees in excess of those which would be required if the dispute were decided in a court of law, and shall pay the arbitrator’s fee.
Nothing in this Agreement is intended to prevent either the Company or Executive from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. 

10.    General Provisions. 

10.1    Notices. Any notices provided must be in writing and will be deemed effective upon
the earlier of personal delivery (including personal delivery by fax) or the next day after sending by overnight carrier, to the Company at its primary office location and to Executive at the address as listed on the Company payroll. 

10.2    Severability. Whenever possible, each provision of this Agreement will be
interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction to the extent possible in keeping with the intent of the
Parties. 
 10.3    Waiver. Any waiver of any breach of any provisions of this Agreement
must be in writing to be effective, and it shall not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement. 

10.4    Complete Agreement. This Agreement, together with the Severance Plan and the
Proprietary Agreement, constitutes the entire agreement between Executive and the Company with regard to the subject matter hereof and is the complete, final, and exclusive embodiment of the Company’s and Executive’s agreement with regard
to this subject matter. This Agreement is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and it supersedes any other such promises, warranties or representations. It
cannot be modified or amended except in a writing signed by a duly authorized officer of the Company, with the exception of those changes expressly reserved to the Company’s discretion in this Agreement. 

10.5    Counterparts. This Agreement may be executed in separate counterparts, any one of
which need not contain signatures of more than one party, but both of which taken together will constitute one and the same Agreement. 

10.6    Headings. The headings of the paragraphs hereof are inserted for convenience only
and shall not be deemed to constitute a part hereof nor to affect the meaning thereof. 

  
 5. 

 10.7    Successors and Assigns. This
Agreement is intended to bind and inure to the benefit of and be enforceable by Executive and the Company, and their respective successors, assigns, heirs, executors and administrators, except that Executive may not assign any of Executive’s
duties hereunder and Executive may not assign any of Executive’s rights hereunder without the written consent of the Company, which shall not be withheld unreasonably. 

10.8    Tax Withholding. All payments and awards contemplated or made pursuant to this
Agreement will be subject to withholdings of applicable taxes in compliance with all relevant laws and regulations of all appropriate government authorities. Executive acknowledges and agrees that the Company has neither made any assurances nor any
guarantees concerning the tax treatment of any payments or awards contemplated by or made pursuant to this Agreement. Executive has had the opportunity to retain a tax and financial advisor and fully understands the tax and economic consequences of
all payments and awards made pursuant to this Agreement. 
 10.9    Non-Solicitation. I agree that for the one year period after the date my employment ends, I will not, as an officer, director, employee, consultant, owner, partner, or in any other capacity, either directly or
through others, solicit, induce, encourage, or participate in soliciting, inducing or encouraging any employee, consultant, or independent contractor of Company to terminate his, her or its relationship with Company or its affiliates, even if I did
not initiate the discussion or seek out the contact. 
 10.10    Non-disparagement. I agree not to disparage the Company and its affiliates, and the Company’s and its affiliates’ officers, directors, employees, shareholders, investors and agents, in any manner
likely to be harmful to them or their business, business reputation or personal reputation; provided that I may respond accurately and fully to any question, inquiry or request for information when required by legal process or as part of a
government investigation. Notwithstanding the foregoing, nothing herein shall limit my right to voluntarily communicate with the Equal Employment Opportunity Commission, United States Department of Labor, the National Labor Relations Board, the
Securities and Exchange Commission, other federal government agency or similar state or local agency or to discuss the terms and conditions of my employment with others to the extent expressly permitted by Section 7 of the National Labor
Relations Act. 
 10.11    Choice of Law. All questions concerning the construction,
validity and interpretation of this Agreement will be governed by the laws of the State of California.

 ARTICLE 2 

LEASE TERM AND TENANT’S EARLY CANCELLATION RIGHT 

2.1 Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease except for the
provisions of this Lease relating to the payment of Rent. The term of this Lease (the “Lease Term”) shall be as set forth in Section 7.1 of the Summary and shall commence on the date (the “Lease Commencement
Date”) set forth in Section 7.2 of the Summary (subject, however, to the terms of the Tenant Work Letter), and shall terminate on the date (the “Lease Expiration Date”) set forth in Section 7.3 of the Summary,
unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term, provided that the last Lease Year
shall end on the Lease Expiration Date. If Landlord does not deliver possession of the Premises to Tenant Ready for Occupancy on or before the anticipated Lease Commencement Date (as set forth in Section 7.2(ii) of the Summary), Landlord shall
not be subject to any liability nor shall the validity of this Lease nor the obligations of Tenant hereunder be affected. If the Lease Commencement Date is a date which is other than the anticipated Lease Commencement Date set forth in
Section 7.2(ii) of the Summary, then, following the Lease Commencement Date, Landlord shall deliver to Tenant an amendment to lease in the form attached hereto as Exhibit C, attached hereto, setting forth, among other things, the
Lease Commencement Date and the Lease Expiration Date, and Tenant shall execute and return such amendment to Landlord within five (5) business days after Tenant’s receipt thereof. If Tenant fails to execute and return the amendment within
such 5-business day period, Tenant shall be deemed to have approved and confirmed the dates set forth therein, provided that such deemed approval shall not relieve Tenant of its obligation to execute and
return the amendment (and such failure shall constitute a default by Tenant hereunder). If Landlord does not deliver such amendment to Tenant, the Lease Commencement Date shall be deemed to be the anticipated Lease Commencement Date set forth in
Section 7.2(ii) of the Summary. In the event that Substantial Completion of the Premises has not occurred by August 1, 2016 (the “First Outside Date”), as such First Outside Date may be extended by the number of days of
Tenant Delays (as defined in the Tenant Work Letter) and by the number of days of Force Majeure events (as defined in Section 24.17 hereof), then Landlord agrees to provide Tenant with one (1) day of abatement of Base Rent for each one
(1) day past the First Outside Date (as such date may be extended as provided above) that Substantial Completion of the Premises has failed to occur. In addition, in the event that Substantial Completion of the Premises has not occurred by the
“Second Outside Date,” which Second Outside Date shall be September 1, 2016, as such Second Outside Date may be extended by the number of days of Tenant Delays and by the number of days of “Force Majeure”
events, then the sole remedy of Tenant shall be the right to deliver a notice to Landlord (the “Second Outside Date Termination Notice”) electing to terminate this Lease effective upon receipt of the Second Outside Date Termination
Notice by Landlord (the “Effective Date”). Except as provided herein below, the Second Outside Date Termination Notice must be delivered by Tenant to Landlord, if at all, not earlier than the Second Outside Date and not later than
five (5) business days after the Second Outside Date. If Tenant delivers the Second Outside Date Termination Notice to Landlord, then Landlord shall have the right to suspend the Effective Date for a period ending thirty (30) days after
the original Effective Date. In order to suspend the Effective Date, Landlord must deliver to Tenant, within five (5) business days after receipt of the Second Outside Date Termination Notice, a certificate of the Contractor (as defined in the
Tenant Work Letter) certifying that it is such Contractor’s best good faith judgment that Substantial Completion of the Premises will occur within thirty (30) days after the original Effective Date. If Substantial Completion of the
Premises occurs within said thirty (30) day suspension period, then the Second Outside Date Termination Notice shall be of no further force and effect; if, however. Substantial Completion of the Premises does not occur within said thirty
(30) day suspension period, then this Lease shall terminate as of the date of expiration of such thirty (30) day period. Upon termination of this Lease pursuant to this Section 2.1. the parties shall be relieved of all further
obligations under this Lease except for those obligations under this Lease which expressly survive the expiration or sooner termination of this Lease. 

2.2 Tenant’s Early Cancellation Right. The original Tenant executing this Lease (“Original
Tenant”) shall have the one (1) time right to terminate and cancel this Lease as it pertains to the initial Premises leased by Tenant hereunder effective as of the date (“Termination Date”) which is the last day of the
thirty-sixth (36th) month of the initial Lease Term, which right is contingent upon Tenant paying to Landlord the Termination Consideration (as defined below) in a timely manner in accordance with the following provisions of this Section 2.2.
To exercise such termination right, Tenant must deliver to Landlord, on or before the date which is nine (9) months prior to the Termination Date, written notice of Tenant’s exercise of such right (the “Termination
Notice”), along with the Termination Consideration. As used herein, the “Termination Consideration” shall mean an amount equal to (i) seven (7) months of monthly Base Rent calculated based on the seven (7) month
period following the Termination Date (i.e., months 37 – 43 which equals Two Hundred Forty-Six Thousand Seven Hundred Ninety Nine and 56/100 Dollars ($246,799.56) in the aggregate) and
(ii) Landlord’s estimate of Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs that would have been payable by Tenant for months 37 – 44 of the initial Lease Term. If Tenant properly and timely exercises its
termination option in this Section 2.2 in strict accordance with the terms hereof, this Lease shall expire at midnight on the Termination Date, and Tenant shall be required to surrender the Premises to Landlord on or prior to the Termination
Date in accordance with the applicable provisions of this Lease. The termination right set forth in this Section 2.2 is personal to the Original Tenant and may only be executed by the Original Tenant (and not any sublessee or other Transferee
of Original Tenant’s 

  

					
		 		 	
		 	-2-	 	
		 		 	

 
interest in this Lease) if the Original Tenant occupies the entire Premises. Notwithstanding anything above to the contrary, Tenant shall have no right to exercise such early cancellation right,
and Tenant’s exercise of such early cancellation right may, at Landlord’s option, be nullified by Landlord and deemed of no further force or effect, if Tenant shall be in material default under the terms of this Lease after the expiration
of applicable cure periods as of Tenant’s exercise of such early cancellation right. For purposes of this Lease, a material default shall mean any monetary default or any material non-monetary default.

 ARTICLE 3

RENT 
 Tenant shall pay, without notice or demand, to Landlord or Landlord’s agent at the management office of
the Building, or at such other place as Landlord may from time to time designate in writing, in currency or a check for currency which, at the time of payment, is legal tender for private or public debts in the United States of America, base rent
(“Base Rent”) as set forth in Section 8 of the Summary, payable in equal monthly installments as set forth in Section 8 of the Summary in advance on or before the first day of each and every month during the Lease Term,
without any setoff or deduction whatsoever. In addition to the Security Deposit, concurrently with Tenant’s execution of this Lease, Tenant shall deliver to Landlord an amount equal to Forty-One Thousand

If any rental payment date (including the Lease Commencement Date) falls on a day of the month
other than the first day of such month or if any rental payment is for a period which is shorter than one month, then the rental for any such fractional month shall be a proportionate amount of a full calendar month’s rental based on the
proportion that the number of days in such fractional month bears to the number of days in the calendar month during which such fractional month occurs. All other payments or adjustments required to be made under the terms of this Lease that require
proration on a time basis shall be prorated on the same basis.

and provided that Tenant faithfully performs all of the terms and conditions of this Lease, Landlord hereby agrees to abate Tenant’s obligation to pay fifty percent (50%) of Tenant’s monthly Base Rent for the second (2nd), third (3rd), fourth (4th), fifth
(5th), sixth (6th), and seventh (7th), full months of the initial Lease Term. In the event
that Tenant does not exercise its termination right in Section 2.2 above, then Landlord further agrees to abate fifty percent (50%) of Tenant’s Monthly Base Rent for the thirty-seventh
(37th), thirty-eighth (38th), thirty-ninth (39th) and fortieth (40th) full months of the initial Lease Term (all such abated monthly Base Rent collectively, the “Abated Rent”). During such abatement period, Tenant shall still be responsible for the
payment of all of its other monetary obligations under this Lease. In the event of a material default by Tenant under the terms of this Lease that results in early termination pursuant to the provisions of Article 19 of this Lease, then as a part of
the recovery set forth in Article 19 of this Lease, Landlord shall be entitled to the recovery of the monthly Base Rent that was abated under the provisions of this Article 3. 

ARTICLE 4

foregoing, as to the Expense Year in which such adjustment occurs, Tenant’s Share for such year shall be determined on the basis of the number of days during such Expense Year that each such Tenant’s Share was in effect. 

4.2.7 “Utilities Costs” shall mean all actual charges for utilities for the Building and the Project
(including utilities for the Other Existing Buildings and additional buildings, if any, added to the Project during the period of time the same are included by Landlord within the Project) which Landlord shall pay during any Expense Year, including,

amount equal to the additional Utilities Costs which would reasonably have been incurred during

such period by Landlord if Landlord had at its own expense provided such utilities to such tenant. Utilities Costs shall include any costs of utilities which are allocated to the Project under
any declaration, restrictive covenant, or other instrument pertaining to the sharing of costs by the Project or any portion thereof, including any covenants, conditions or restrictions now or hereafter recorded against or affecting the Project. 

4.3 Calculation and Payment of Additional Rent. 

4.3.1 Payment of Operating Expenses, Tax Expenses and Utilities Costs. For each Expense Year ending or commencing within
the Lease Term, Tenant shall pay to Landlord. as Additional Rent, the following, which payment shall be made in the manner set forth in Section 4.3.2 below: (i) Tenant’s Share of Operating Expenses allocated to the Building pursuant
to Section 4.3.4 below; plus (ii) Tenant’s Share of Tax Expenses allocated to the Building pursuant to Section 4.3.4 below; plus (iii) Tenant’s Share of Utilities Costs allocated to the Building pursuant to
Section 4.3.4 below. 
 4.3.2 Statement of Actual Operating Expenses, Tax Expenses and Utilities Costs and Payment by
Tenant. Landlord shall give to Tenant on or before the first (1st) day of June following the end of each Expense Year (or as soon thereafter as reasonably possible) a statement (the
“Statement”) which shall state the Operating Expenses, Tax Expenses and Utilities Costs incurred or accrued for such preceding Expense Year that are allocated to the Building pursuant to Section 4.3.4 below, and which shall
indicate therein Tenant’s Share thereof. Within sixty (60) days after Tenant’s receipt of the Statement for each Expense Year ending during the Lease Term, Tenant shall pay to Landlord the full amount of the Tenant’s Share of
Operating Expenses, Tax Expenses and Utilities Costs for such Expense Year, less the amounts, if any, paid during such Expense Year as the Estimated Expenses as defined in and pursuant to Section 4.3.3 below. If any Statement reflects that
Tenant has overpaid Tenant’s Share of Operating Expenses and/or Tenant’s Share of Tax Expenses and/or Tenant’s Share of Utilities Costs for such Expense Year, then Landlord shall remit such overpayment to Tenant within thirty
(30) days after such applicable Statement is delivered to Tenant. Even though the Lease Term has expired and Tenant has vacated the Premises, if the Statement for the Expense Year in which this Lease terminates reflects that Tenant has overpaid
and/or underpaid Tenant’s Share of the Operating Expenses and/or Tenant’s Share of Tax Expenses and/or Tenant’s Share of Utilities Costs for such Expense Year, then within thirty (30) days after Landlord’s delivery of such
Statement to Tenant, Landlord shall refund to Tenant any such overpayment, or Tenant shall pay to Landlord any such underpayment, as the case may be. The provisions of this Section 4.3.2 shall survive the expiration or earlier termination of
the Lease Term. Notwithstanding the foregoing to the contrary, Tenant shall not be responsible for Tenant’s Share of any Direct Expenses attributable to any Expense Year which was first billed to Tenant more than two (2) Calendar Years
after the date (the “Cutoff Date”) which is the earlier of (i) the expiration of the applicable Expense Year or (ii) the Lease Expiration Date, except that Tenant shall be responsible for Tenant’s Share of Direct
Expenses levied by any governmental authority or by any public utility company at any time following the applicable Cutoff Date which are attributable to any Expense Year occurring prior to such Cutoff Date, so long as Landlord delivers to Tenant a
bill and supplemental Statement for such amounts within two (2) years following Landlord’s receipt of the applicable bill therefor. 

4.3.3 Statement of Estimated Operating Expenses, Tax Expenses and Utilities Costs. Landlord shall give Tenant a yearly
expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of the total amount of Tenant’s Share of the Operating Expenses, Tax Expenses and
Utilities Costs allocated to the Building pursuant to Section 4.3.4 below for the then-current Expense Year shall be, and which shall indicate therein Tenant’s Share thereof (the “Estimated Expenses”). The failure of
Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Expenses under this Article 4 once such Estimate Statement is ultimately provided to Tenant.
Following Landlord’s delivery of the Estimate Statement for the then-current Expense Year, Tenant shall pay, with its next installment of Base Rent due, a fraction of the Estimated Expenses for the then-current Expense Year (reduced by any
amounts paid pursuant to the last sentence of this Section 4.3.3). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year to the month of such payment, both months inclusive, and shall
have twelve (12) as its denominator. Until a new Estimate Statement is furnished, Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total
Estimated Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant. 
 4.3.4 Allocation of
Operating Expenses, Tax Expenses and Utilities Costs to Building. The parties acknowledge that the Building is part of a multi-building commercial project consisting of the Building, and the Other Existing Buildings and such other buildings as
Landlord (and/or any other owners of Torrey Ridge Science Center) may elect to construct and include as part of the Project from time to time (the Other Existing Buildings and any such other buildings are sometimes referred to herein, collectively,
as the “Other Buildings”), and that certain of the costs and expenses incurred in connection with the Project (i.e. the Operating Expenses, Tax Expenses and Utilities Costs) shall be shared among the Building and/or such Other
Buildings, while certain other costs and expenses which are solely attributable to the Building and such Other Buildings, as applicable, shall be allocated directly to the Building and the Other Buildings, respectively. Accordingly, as set forth in
Sections 4.1 and 4.2 above, Operating Expenses, Tax Expenses and Utilities Costs are determined annually for the Project as a whole, and a portion of the Operating Expenses, Tax Expenses and Utilities Costs, which portion shall be determined by
Landlord on an equitable basis, shall be allocated to the Building (as opposed to the tenants of the Other Buildings), and such portion so allocated shall be the amount of Operating Expenses, Tax Expenses and Utilities Costs payable with respect to
the Building upon which Tenant’s Share shall be calculated. Such portion of the Operating Expenses, Tax Expenses and Utilities Costs allocated to the Building shall include all Operating Expenses, Tax Expenses and Utilities Costs which are
attributable solely to the Building, and an equitable portion of the Operating Expenses, Tax Expenses and Utilities Costs attributable to the Project as a whole. As an example of such allocation with respect to Tax Expenses and Utilities Costs, it
is anticipated that Landlord (and/or 

  

					
		 		 	
		 	-6-	 	
		 		 	

 
any other owners of Torrey Ridge Science Center) may receive separate tax bills which separately assess the improvements component of Tax Expenses for each building in the Project and/or Landlord
may receive separate utilities bills from the utilities companies identifying the Utilities Costs for certain of the utilities costs directly incurred by each such building (as measured by separate meters installed for each such building), and such
separately assessed Tax Expenses and separately metered Utilities Costs shall be calculated for and allocated separately to each such applicable building. In addition, in the event Landlord (and/or any other owners of Torrey Ridge Science Center)
elect to subdivide certain common area portions of the Project such as landscaping, public and private streets, driveways, walkways, courtyards, plazas, transportation facilitation areas and/or accessways into a separate parcel or parcels of land
(and/or separately convey all or any of such parcels to a common area association to own, operate and/or maintain same), the Operating Expenses, Tax Expenses and Utilities Costs for such common area parcels of land may be aggregated and then
reasonably allocated by Landlord to the Building and such Other Buildings on an equitable basis as Landlord (and/or any applicable covenants, conditions and restrictions for any such common area association) shall provide from time to time. 

4.3.5 Cap on Controllable Operating Expenses. Notwithstanding anything to the contrary contained in this Article 4, the
aggregate “Controllable Expenses” (as hereinafter defined) included in Operating Expenses in any Expense Year after the first Expense Year shall not increase by more than six percent (6%) on an annual, cumulative basis, over the
actual aggregate Controllable Expenses included in Operating Expenses for any preceding Expense Year, but with no such limit on the amount of Controllable Expenses which may be included in the Operating Expenses incurred during the first Expense
Year. For purposes of this Section 4.3.5, “Controllable Expenses” shall mean all Operating Expenses except: (i) government-mandated charges with respect to the Building or Real Property, or any part thereof; and
(ii) insurance carried by Landlord with respect to the Real Property and/or the operation thereof. The provisions of this Section 4.3.5 do not apply to the Tax Expenses nor Utilities Costs. 

4.4 Taxes and Other Charges for Which Tenant is Directly Responsible. Tenant shall reimburse Landlord upon demand for
all taxes or assessments required to be paid by Landlord (except to the extent included in Tax Expenses by Landlord), excluding state, local and federal personal or corporate income taxes measured by the net income of Landlord from all sources and
estate and inheritance taxes, whether or not now customary or within the contemplation of the parties hereto, when. 
 4.4.1
said taxes are measured by or reasonably attributable to the cost or value of Tenant’s equipment, furniture, fixtures and other personal property located in the Premises, or by the cost or value of any leasehold improvements made in or to the
Premises by or for Tenant, to the extent the cost or value of such leasehold improvements exceeds the cost or value of a building standard build-out as determined by Landlord regardless of whether title to
such improvements shall be vested in Tenant or Landlord; 
 4.4.2 said taxes are assessed upon or with respect to the
possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project; or 

4.4.3 said taxes are assessed upon this transaction or any document to which Tenant is a party creating or transferring an
interest or an estate in the Premises. 
 4.5 Late Charges. If any installment of Rent or any other sum due from
Tenant shall not be received by Landlord or Landlord’s designee by the due date therefor, then Tenant shall pay to Landlord a late charge equal to ten percent (10%) of the amount due plus any attorneys’ fees incurred by Landlord by reason
of Tenant’s failure to pay Rent and/or other charges when due hereunder; provided, however, that Landlord will waive the imposition of the late charge for the first late payment of rent in any twelve (12) month period. The late charge
shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder, at law and/or in equity and shall not be construed as liquidated damages or as limiting Landlord’s
remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid by the date that they are due shall thereafter bear interest until paid at a rate (the “Interest
Rate”) equal to the lesser of (i) the “Prime Rate” or “Reference Rate” announced from time to time by the Bank of America (or such reasonable comparable national banking institution as selected by
Landlord in the event Bank of America ceases to exist or publish a Prime Rate or Reference Rate), plus four percent (4%), or (ii) the highest rate permitted by applicable law. 

4.6 Audit Rights. Tenant shall have the right, at Tenant’s cost, after reasonable notice to Landlord, to have
Tenant’s authorized employees or agents inspect, at Landlord’s main corporate office during normal business hours, Landlord’s books, records and supporting documents concerning the Operating Expenses, Tax Expenses and Utilities Costs
set forth in any Statement delivered by Landlord to Tenant for a particular Expense Year pursuant to Section 4.3.2 above; provided, however, Tenant shall have no right to conduct such inspection or object to or otherwise dispute the amount of
the Operating Expenses, Tax Expenses and/or Utilities Costs set forth in any such Statement, unless Tenant notifies Landlord of such inspection objection and dispute, and completes such inspection within twelve (12) months immediately following
Landlord’s delivery of the particular Statement in question (the “Review Period”); provided, further, that notwithstanding any such timely inspection, objection, dispute, and/or audit, and as a condition precedent to
Tenant’s exercise of its right of inspection, objection, dispute, and/or audit as set forth in this Section 4.6, Tenant shall not be permitted to withhold payment of, and Tenant shall timely pay to Landlord, the full amounts as required by
the provisions of this Article 4 in accordance with such Statement. However, such payment may be made under protest pending the outcome of any audit. In connection with any such inspection by Tenant, Landlord and Tenant shall reasonably cooperate
with each other so that such inspection can be performed pursuant to a mutually acceptable schedule, in an expeditious manner and without undue interference with Landlord’s operation and management of the Project. If after such inspection
and/or request for documentation, Tenant disputes the amount of the Operating Expenses, Tax Expenses and/or Utilities Costs set forth in the Statement, Tenant shall have the right, but not the obligation, within the

  

					
		 		 	
		 	-7-	 	
		 		 	

 
Review Period, to cause an independent certified public accountant which is not paid on a contingency basis and which is mutually and reasonably approved by Landlord and Tenant (the
“Accountant”) to complete an audit of Landlord’s books and records to determine the proper amount of the Operating Expenses, Tax Expenses and Utilities Costs incurred and amounts payable by Tenant for the Expense Year which is
the subject of such Statement. Such audit by the Accountant shall be final and binding upon Landlord and Tenant. If Landlord and Tenant cannot mutually agree as to the identity of the Accountant within thirty (30) days after Tenant notifies
Landlord that Tenant desires an audit to be performed, then the Accountant shall be one of the “Big 4” accounting firms selected by Landlord, which is not paid on a contingency basis. If such audit reveals that Landlord has over-charged
Tenant, then within thirty (30) days after the results of such audit are made available to Landlord, Landlord shall reimburse to Tenant the amount of such over-charge. If the audit reveals that the Tenant was under-charged, then within thirty
(30) days after the results of such audit are made available to Tenant, Tenant shall reimburse to Landlord the amount of such under-charge. Tenant agrees to pay the cost of such audit unless it is subsequently determined that Landlord’s
original Statement which was the subject of such audit was in error to Tenant’s disadvantage by five percent (5%) or more of the total Operating Expenses, Tax Expenses and/or Utilities Costs which was the subject of such audit. The payment by
Tenant of any amounts pursuant to this Article 4 shall not preclude Tenant from questioning the correctness of any Statement provided by Landlord at any time during the Review Period, but the failure of Tenant to object thereto, conduct and complete
its inspection and have the Accountant conduct and complete the audit as described above prior to the expiration of the Review Period shall be conclusively deemed Tenant’s approval of the Statement in question and the amount of Operating
Expenses. Tax Expenses and Utilities Costs shown thereon. In connection with any inspection and/or audit conducted by Tenant pursuant to this Section 4.6, Tenant agrees to keep, and to cause all of Tenant’s employees and consultants and
the Accountant to keep, all of Landlord’s books and records and the audit, and all information pertaining thereto and the results thereof, strictly confidential, and in connection therewith, Tenant shall cause such employees, consultants and
the Accountant to execute such reasonable confidentiality agreements as Landlord may require prior to conducting any such inspections and/or audits.

PREMISES: HAZARDOUS MATERIALS; ODORS AND EXHAUST 
 5.1 Use. Tenant shall use the Premises solely for
laboratory and office purposes, all to the extent consistent with the character of the Building as a first-class biotechnology building, and Tenant shall not use or permit the Premises to be used for any other purpose or purposes whatsoever. Tenant
shall not use, or suffer or permit any person or persons to use, the Premises or any part thereof for any use or purpose contrary to the provisions of Exhibit D. attached hereto, or in violation of the laws of the United States of
America, the state in which the Project is located, or the ordinances, regulations or requirements of the local municipal or county governing body or other lawful authorities having jurisdiction over the Project. Tenant shall comply with the Rules

 5.2.2 Tenant’s Obligations – Environmental Permits. Tenant
will (i) obtain and maintain in full force and effect all Environmental Permits that may be required from time to time under any Environmental Laws applicable to Tenant or the Premises and (ii) be and remain in compliance with all terms
and conditions of all such Environmental Permits and with all other limitations, restrictions, conditions, standards, prohibitions, requirements, obligations, schedules and timetables contained in all Environmental Laws applicable to Tenant or the
Premises. On or before the date Tenant commences business operations in the Premises and thereafter from time to time upon Landlord’s written request, Tenant shall provide to Landlord all Environmental Permits pertaining to the Premises and
Tenant’s business operations therein. 
 5.2.3 Tenant’s Obligations – Hazardous Materials. Except as
expressly permitted herein, Tenant agrees not to cause or permit any Hazardous Materials to be brought upon, stored, used, handled, generated, released or disposed of on, in, under or about the Premises. or any other portion of the Property by
Tenant, its agents, employees, subtenants, assignees, licensees, contractors or invitees (collectively, “Tenant’s Parties”), without the prior written consent of Landlord, which consent Landlord may withhold in its sole and
absolute discretion. Landlord hereby acknowledges and agrees that it is not the intent of this Section 5.2 to prohibit Tenant from operating its business for the uses permitted hereunder and that Tenant shall be permitted to operate its
business according to the custom of Tenant’s industry so long as the use or presence of Hazardous Materials is strictly and properly monitored in accordance with applicable Environmental Laws. As a material inducement to Landlord to allow
Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Lease Commencement Date a list identifying each type of Hazardous Material to be present at the Premises and setting forth any and
all governmental approvals or permits required in connection with the presence of such Hazardous Material at the Premises (the “Hazardous Materials List”). Tenant shall deliver to Landlord an updated Hazardous Materials List on or
prior to each annual anniversary of the Lease Commencement Date and shall also deliver an updated Hazardous Materials List before any new Hazardous Materials are brought to the Premises. Tenant shall deliver to Landlord true and correct copies of
the following documents (hereinafter referred to as the “Documents”) relating to the handling, storage, disposal and emission of Hazardous Materials prior to the Lease Commencement Date or, if unavailable at that time, concurrently
with the receipt from or submission to any Governmental Authority: permits; approvals; reports and correspondence; storage and management plans; notices of violations of applicable Environmental Laws; plans relating to the installation of any
storage tanks to be installed in, on, under or about the Premises (provided that installation of storage tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent Landlord may withhold in its sole and
absolute discretion); and all closure plans or any other documents required by any and all governmental authorities for any storage tanks installed in, on, under or about the Premises for the closure of any such storage tanks. Tenant shall not be
required, however, to provide Landlord with any portion of the Documents containing information of a proprietary nature, which Documents, in and of themselves, do not contain a reference to any Hazardous Materials or activities related to Hazardous
Materials. Upon the expiration or earlier termination of this Lease, Tenant agrees to promptly remove from the Premises, the Building and the Project, at its sole cost and expense, any and all Hazardous Materials, including any equipment or systems
containing Hazardous Materials which are installed, brought upon, stored, used, generated or released upon, in, under or about the Premises, the Building and/or the Project or any portion thereof by Tenant or any of Tenant’s Parties during the
Term of this Lease. 
 5.2.4 Landlord’s Right to Conduct Environmental Assessment. At any time during the Lease
Term, Landlord shall have the right to conduct an environmental assessment of the Premises (as well as any other areas in, on or about the Project that Landlord reasonably believes may have been affected adversely by Tenant’s use of the
Premises (collectively, the “Affected Areas”) in order to confirm that the Premises and the Affected Areas do not contain any Hazardous Materials in violation of applicable Environmental Laws or under conditions constituting or
likely to constitute a Release of Hazardous Materials. Such environmental assessment shall be a so-called “Phase I” assessment or such other level of investigation which shall be the standard
of diligence in the purchase or lease of similar property at the time, together with any additional investigation and report which would customarily follow any discovery contained in such initial Phase 1 assessment (including, but not limited to,
any so-called “Phase II” report). Such right to conduct such environmental assessment shall not be exercised more than once per calendar year unless Tenant is in default under this
Section 5.2 (beyond the expiration of all applicable notice and cure periods). Tenant shall reimburse Landlord for the cost of all environmental assessments of Affected Areas that indicate a conclusive and proximate connection between
Tenant’s use and occupancy of the Premises and the presence of Hazardous Materials in violation of applicable Environmental Laws that did not exist on the Premises prior to Tenant’s possession thereof, 

5.2.5 Tenant’s Obligations to perform Corrective Action. If the data from any environmental assessment authorized
and undertaken by Landlord pursuant to Section 5.2.4 indicates that (i) there has been a Release. threatened Release or other conditions with respect to Hazardous Materials on, under or emanating from the Premises and the Affected Areas in
violation of applicable Environmental Laws caused by Tenant (“Tenant Release”), and (ii) such Tenant Release requires any investigation and/or active response action, including without limitation active or passive remediation
and monitoring or any combination of these activities (“Corrective Action”), then Tenant shall immediately undertake Corrective Action with respect to contamination if, and to the extent, required by the governmental authority
exercising jurisdiction over the matter. Any Corrective Action performed by Tenant will be performed with Landlord’s prior written approval and in accordance with applicable Environmental Laws, at Tenant’s sole cost and expense and by an
environmental consulting firm (reasonably acceptable to Landlord) Tenant may perform the Corrective Action before or after the expiration or earlier termination of this Lease, to the extent permitted by governmental agencies with jurisdiction over
the Premises, the Building and the Project (provided, however, that any Corrective Action performed after the expiration or earlier termination of this Lease shall be subject to the access fee provisions set forth below). If Tenant undertakes or
continues Corrective Action after the expiration or earlier termination of this Lease, Landlord, upon being given forty-eight (48) hours’ advance notice, may, in Landlord’s sole discretion, elect (without limiting any of the
Landlord’s other rights and remedies under this Lease, at law and/or in equity), to provide, at an “access fee” equal to one 

  

					
		 		 	
		 	-9-	 	
		 		 	

 
hundred fifty percent (150%) of the Monthly Rent in effect for the last month immediately preceding the expiration or earlier termination of this Lease, plus all other sums due under this Lease,
access to the Premises, the Building and the Project as may be requested by Tenant and its consultant to accomplish the Corrective Action. Tenant or its consultant may install, inspect, maintain, replace and operate remediation equipment and conduct
the Corrective Action as it considers necessary, subject to Landlord’s reasonable approval. Tenant and Landlord shall, in good faith, cooperate with each other with respect to any Corrective Action after the expiration or earlier termination of
this Lease so as not to interfere unreasonably with the conduct of Landlord’s or any third party’s business on the Premises, the Building and the Project. Landlord shall provide access until Tenant delivers evidence reasonably satisfactory
to Landlord that Tenant’s Corrective Action activities on the Premises and the Affected Areas satisfy applicable Environmental Laws. It shall be reasonable for Landlord to require Tenant to deliver a “no further action” letter or
substantially similar document from the applicable governmental agency. Landlord shall continue to provide access and Tenant shall continue to pay the access fee until such time as Landlord is able to use the Premises and the Affected Areas for such
purposes as Landlord reasonably desires, Landlord’s “reasonableness” as used in the immediately preceding sentence shall be based on (i) the zoning of the Premises as of the date in question, and (ii) the logical uses of the
Premises as of the date in question. If Landlord desires to situate a tenant in the Premises, the Building and the Project and remediation of the Premises and the Affected Areas is ongoing, Landlord shall be deemed to be unable to use the Premises,
the Building and the Project in the way Landlord reasonably desires and Tenant shall be obligated to continue paying the access fee until such time as Landlord is able to situate said tenant in the Premises, the Building and/or the Project. Tenant
agrees, to the extent applicable and reasonably practicable, to install, at Tenant’s sole cost and expense, screening around its remediation equipment so as to protect the aesthetic appeal of the Premises, the Building and the Project. Tenant
also agrees to use reasonable efforts to locate its remediation and/or monitoring equipment, if any (subject to the requirements of Tenant’s consultant and governmental agencies with jurisdiction over the Premises, the Building and the Project)
in a location which will allow Landlord, to the extent reasonably practicable, the ability to lease the Premises, the Building and the Project to a subsequent user. Any Hazardous Materials contamination on, in, under or about the Premises and the
Affected Areas at the expiration or earlier termination of this Lease which is not disclosed by Tenant prior to the effective date of this Lease shall be presumed to have arisen in connection with Tenant’s environmental activities under the
Lease. Notwithstanding anything above to the contrary, if any clean-up or monitoring procedure is required by any applicable governmental authorities in, on, under or about the Premises and the Affected Areas
during the Lease Term as a consequence of any Hazardous Materials contamination and the procedure for clean-up is not completed (to the satisfaction of Landlord and/or the governmental authorities) prior to
the expiration or earlier termination of this Lease then, at Landlord’s election, (i) this Lease shall be deemed renewed for a term commencing on the expiration or earlier termination of this Lease and ending on the date the clean-up procedure is anticipated to be completed; or (ii) Tenant shall be deemed to have impermissibly held over (and Article 16 of this Lease shall apply with full force and effect) and Landlord shall be
entitled to all damages directly or indirectly incurred, including, without limitation, damages occasioned by the inability to relet the Premises and/or any other portion of the Building or a reduction of the fair market or rental value of the
Premises and/or the Building. 
 5.2.6 Tenant’s Duty to Notify Landlord Regarding Releases. Tenant agrees to
promptly notify Landlord of any Release of Hazardous Materials in the Premises, the Building or any other portion of the Project which Tenant becomes aware of during the Term of this Lease, whether caused by Tenant or any other persons or entities.
In the event of any release of Hazardous Materials caused or permitted by Tenant or any of Tenant’s Parties, Landlord shall have the right, but not the obligation, to cause Tenant, at Tenant’s sole cost and expense, to immediately take all
reasonable steps Landlord deems necessary or appropriate to remediate such Release and prevent any similar future release to the satisfaction of Landlord and Landlord’s mortgagee(s). Tenant will, upon the request of Landlord at any time during
which Landlord has reason to believe that Tenant is not in compliance with this Section 5.2 (and in any event no earlier than sixty (60) days and no later than thirty (30) days prior to the expiration of this Lease), cause to be
performed an environmental audit of the Premises at Tenant’s expense by an established environmental consulting firm reasonably acceptable to Landlord. In the event the audit provides that Corrective Action is required then Tenant shall
immediately perform the same at its sole cost and expense. 
 5.2.7 Tenant’s Environmental Indemnity. To the
fullest extent permitted by law, Tenant agrees to promptly indemnify, protect, defend and hold harmless Landlord and Landlord’s members, partners, subpartners, independent contractors, officers, directors, shareholders, employees, agents,
successors and assigns (collectively, “Landlord Parties”) from and against any and all claims, damages, judgments, suits, causes of action, losses, liabilities, penalties, fines, expenses and costs (including, without limitation, clean-up, removal, remediation and restoration costs, sums paid in settlement of claims, attorneys’ fees, consultant fees and expert fees and court costs) which arise or result from the presence of Hazardous
Materials on, in, under or about the Premises, the Building or any other portion of the Property and which are caused or permitted by Tenant or any of Tenant’s Parties during the Term of this Lease, including arising from or caused in whole or
in part, directly or indirectly, by (i) the presence in, on, under or about the Premises and the Affected Areas, of any Hazardous Materials; (ii) Tenant’s or other user’s actual, proposed or threatened use, treatment, storage,
transportation, holding, existence, disposition, manufacturing, control, management, abatement, removal, handling, transfer, generation or Release (past, present or threatened) of Hazardous Materials to, in, on, under, about or from the Premises and
the Affected Areas; (iii) any past, present or threatened non-compliance or violations of any Environmental Laws in connection with Tenant and/or the Premises and/or the Affected Areas, (iv) personal
injury claims (v) the payment of any environmental liens, or the disposition, recording, or filing or threatened disposition, recording or filing of any environmental lien encumbering or otherwise affecting the Premises and/or the Affected
Areas, (vi) diminution in the value of the Premises and/or the Project, (vii) damages for the loss or restriction of use of the Premises and/or the Project, including prospective rent, lost profits and business opportunities,
(viii) sums paid in settlement of claims, (ix) reasonable attorneys’ fees, consulting fees and expert fees, (x) the cost of any investigation of site conditions, and (xi) the cost of any repair, clean-up or remediation ordered by any governmental or quasi-governmental agency or body or otherwise deemed necessary in Landlord’s reasonable judgment. Tenant’s obligations

  

					
		 		 	
		 	-10-	 	
		 		 	

 
hereunder shall include, without limitation, and whether foreseeable or unforeseeable, all costs of any required or necessary repair, cleanup or detoxification or decontamination of the Premises,
the Building and/or the Project, or the preparation and implementation of any closure, remedial action or other required plans in connection therewith. For purposes of the indemnity provisions in this Section 5.2, any acts or omissions of
Tenant and/or Tenant’s Parties or others acting for or on behalf of Tenant (whether or not they are negligent, intentional, willful or unlawful) shall be strictly attributable to Tenant. The provisions of this Section 5.2.7 will survive
the expiration or earlier termination of this Lease. 
 5.2.8 Tenant warrants, represents, acknowledges and agrees that
Tenant has performed all investigations appropriate under the circumstances to determine whether any violations of Hazardous Materials Laws currently exist. Tenant shall have no right or remedy against Landlord with respect to any such violation and
Tenant hereby releases, waives and forever discharges Landlord and the Landlord Parties from any and all claims, demands and causes of action, whether known or unknown to Tenant, which Tenant may now or hereafter have arising out of connected with
or incidental to the existence of any Hazardous Material now or hereafter on or about the Premises or the Project. Tenant is aware of the provisions of Section 1542 of the California Civil Code which provides as follows: 

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT
THE TIME OF EXECUTING THE RELEASE WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” 

and, after consultation with counsel concerning the meaning and effect of such waiver, Tenant specifically waives the benefit of the
provisions of Section 1542 of the California Civil Code. 
 5.2.9 Landlord’s Termination Option for Certain
Environmental Problems. If Hazardous Materials are present at the Premises that are required by Environmental Law to be remediated and Tenant is not responsible therefor pursuant to Section 5.2, Landlord may, at its option, either
(i) remediate such Hazardous Materials, in which event this Lease shall continue in full force and effect or if the estimated cost to remediate such Hazardous Materials exceeds One Million Five Hundred Thousand Dollars ($1,500,000.00) (the
“Threshold Amount”), give written notice to Tenant, within thirty (30) days after receipt by Landlord of knowledge of the existence of such Hazardous Materials, of Landlord’s desire to terminate this Lease as of the date
ninety (90) days following the date of such notice. In the event Landlord elects to give such a termination notice. Tenant may, within ten (10) days thereafter, give written notice to Landlord of Tenant’s commitment to pay the amount
by which the cost of the remediation of such Hazardous Materials exceeds the Threshold Amount, Tenant shall provide Landlord with such funds or satisfactory assurance thereof within thirty (30) days following such commitment. In such event,
this Lease shall continue in full force and effect, and Landlord shall proceed to make such remediation as soon as reasonably possible after the required funds are available. If Tenant does not give such notice and provide the required funds or
assurance thereof within the time provided, this Lease shall terminate as the date specified in Landlords termination notice. 

5.3 Odors and Exhaust. Tenant acknowledges that Landlord would not enter into this Lease with Tenant unless Tenant
assured Landlord that under no circumstances will the Premises be damaged by any exhaust from Tenant’s operations. Landlord and Tenant therefore agree as follows: 

5.3.1 Tenant shall not cause or permit (or conduct any activities that would cause) any release of any odors or fumes of any
kind from the Premises that would be offensive or objectionable. 
 5.3.2 If the Building has a ventilation system that, in
Landlord’s judgment, is adequate, suitable, and appropriate to vent the Premises in a manner that does not release odors affecting any indoor or outdoor part of the Premises, Tenant shall vent the Premises through such system. If Landlord at
any time determines that any existing ventilation system is inadequate, or if no ventilation system exists, Tenant shall in compliance with applicable laws vent all fumes and odors from the Premises (and remove odors from Tenant’s exhaust
stream) as Landlord requires. The placement and configuration of all ventilation exhaust pipes, louvers and other equipment shall be subject to Landlord’s approval. Tenant acknowledges Landlord’s legitimate desire to maintain the Premises
(indoor and outdoor areas) in an odor-free manner, and Landlord may require Tenant to abate and remove all odors in a manner that goes beyond the requirements of Applicable Laws. 

5.3.3 Tenant shall, at Tenant’s sole cost and expense, provide odor eliminators and other devices (such as filters, air
cleaners, scrubbers and whatever other equipment may in Landlord’s judgment be necessary or appropriate from time to time) to completely remove, eliminate and abate any odors, fumes or other substances in Tenant’s exhaust stream that, in
Landlord’s judgment, emanate from the Premises. Any work Tenant performs under this Section 5.3 shall constitute Alterations, 

5.3.4 Tenant’s responsibility to remove, eliminate and abate odors, fumes and exhaust shall continue throughout the Term.

 5.3.5 If Tenant fails to install satisfactory odor control equipment within ten (10) business days after
Landlord’s demand made at any time, then Landlord may, without limiting Landlord’s other rights and remedies, require Tenant to cease and suspend any operations in the Premises that, in Landlord’s determination, cause odors, fumes or
exhaust.

 5.4 Control Areas. At Landlord’s option and discretion, Tenant
shall be allowed to utilize up to its pro rata share of the Hazardous Materials inventory within any control area or zone (located within the Premises), as designated by the applicable building code, for chemical use or storage. As used in the
preceding sentence, Tenant’s pro rata share of any control areas or zones located within the Premises shall be determined based on the rentable square footage that Tenant leases within the applicable control area or zone. For purposes of
example only, if a control area or zone contains 10,000 rentable square feet and 2,000 rentable square feet of a tenant’s premises are located within such control area or zone (while such premises as a whole contains 5,000 rentable square
feet), the applicable tenant’s pro rata share of such control area would be 20%,

 ARTICLE 8 

ADDITIONS AND ALTERATIONS 

8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions or changes to
the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than thirty (30) days prior to the
commencement thereof, and which consent shall not be unreasonably withheld by Landlord; provided, however, Landlord may withhold its consent in its sole and absolute discretion with respect to any Alterations which may affect the structural
components of the Building or the Systems and Equipment or which can be seen from outside the Premises. Tenant shall pay for all overhead, general conditions, fees and other costs and expenses of the Alterations, and shall pay to Landlord a Landlord
supervision fee of ten percent (10%) of the cost of the Alterations. The construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8. 

8.2 Manner of Construction. Landlord may impose, as a condition of its consent to all Alterations or repairs of the
Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that Tenant utilize for such purposes only contractors, materials, mechanics and materialmen approved by
Landlord; provided, however, Landlord may impose such requirements as Landlord may determine, in its sole and absolute discretion, with respect to any work affecting the structural components of the Building or Systems and Equipment (including
designating specific contractors to perform such work). In any event, all of Tenant’s contractors and subcontractors shall maintain the applicable insurance required in Exhibit E and Tenant shall ensure that Tenant’s contractors and
subcontractors comply with the requirements set forth therein. Tenant shall construct such Alterations and perform such repairs in compliance with any and all applicable rules and regulations of any federal, state, county or municipal code or
ordinance and pursuant to a valid building permit, issued by the city in which the Building is located, and in conformance with Landlord’s construction rules and regulations. Landlord’s approval of the plans, specifications and working
drawings for Tenant’s Alterations shall create no responsibility or liability on the part of Landlord for their completeness, design sufficiency, or compliance with all laws, rules and regulations of governmental agencies or authorities. All
work with respect to any Alterations must be done in a good and workmanlike manner and diligently prosecuted to completion to the end that the Premises shall at all times be a complete unit except during the period of work. Tenant shall cause all
Alterations to be performed in such manner as not to obstruct access by any person to the Building or Project or the common areas, and as not to obstruct the business of Landlord or other tenants of the Project, or interfere with the labor force
working at the Project. If Tenant makes any Alterations, Tenant agrees to carry “Builder’s All Risk” insurance in an amount approved by Landlord covering the construction of such Alterations, and such other insurance as
Landlord may require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 below immediately upon completion thereof. Landlord may, in its discretion, require Tenant to obtain a lien and
completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee. Upon completion of any Alterations, Tenant shall

fixtures and/or equipment which may be installed or placed in or about the Premises shall be at the sole cost of Tenant and shall be and become the property of Landlord. Furthermore, Landlord may require that Tenant remove any improvement (including
any portion of the Tenant Improvements) or Alteration upon the expiration or early termination of the Lease Term, and repair any damage to the Premises and Building caused by such removal. If Tenant fails to complete such removal and/or to repair by
the end of the Lease Term, Landlord may do so and may charge the cost thereof to Tenant.

Network”) in the Premises for the use by Tenant and its employees, then the same shall be subject to the provisions of this Section 8.4 (in addition to the other provisions of this Article 8). In the event Landlord consents to
Tenant’s installation of such Wi-Fi Network, Tenant shall, in accordance with Article 15 below, remove the Wi-Fi Network from the Premises prior to the termination
of the Lease. Tenant shall use the Wi-Fi Network so as not to cause any interference to other tenants in the Building or to other tenants at the Project or with any other tenant’s communication equipment,
and not to damage the Building or Project or interfere with the normal operation of the Building or Project, and Tenant hereby agrees to indemnify, defend and hold Landlord harmless from and against any and all claims, costs, damages, expenses and
liabilities (including attorneys’ fees) arising out of Tenant’s failure to comply with the provisions of this Section 8.4, except to the extent same is caused by the gross negligence or willful misconduct of Landlord and which is not
covered by the insurance carried by Tenant under this Lease (or which would not be covered by the insurance required to be carried by Tenant under this Lease). Should any interference occur, Tenant shall take all necessary steps as soon as
reasonably possible and no later than three (3) calendar days following such occurrence to correct such interference. If such interference continues after such three (3) day period, Tenant shall immediately cease operating such Wi-Fi Network until such interference is corrected or remedied to Landlord’s satisfaction. Tenant acknowledges that Landlord has granted and/or may grant telecommunication rights to other tenants and occupants
of the Building and Project and to telecommunication service providers and in no event shall Landlord be liable to Tenant for any interference of the same with such Wi-Fi Network. Landlord makes no
representation that the Wi-Fi Network will be able to receive or transmit communication signals without interference or disturbance. Tenant shall (i) be solely responsible for any damage caused as a
result of the Wi-Fi Network, (ii) promptly pay any tax, license or permit fees charged pursuant to any laws or regulations in connection with the installation, maintenance or use

replacements to or maintenance of the Wi-Fi Network, and (iv) be responsible for any modifications, additions or repairs to the Building or Project, including without limitation, Building or Project
systems or infrastructure, which are required by reason of the installation, operation or removal of Tenant’s Wi-Fi Network, Should Landlord be required to retain professionals to research any
interference issues that may arise and confirm Tenant’s compliance with the terms of this Section 8.4, Tenant shall reimburse Landlord for the costs incurred by Landlord in connection with Landlord’s retention of such professionals,
the research of such interference issues and confirmation of Tenant’s compliance with the terms of this Section 8.4 within twenty (20) days after the date Landlord submits to Tenant an invoice for such costs. This reimbursement
obligation is in addition to, and not in lieu of, any rights or remedies Landlord may have in the event of a breach or default by Tenant under this Lease.

whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon the Project, Building or Premises, and any and all liens and encumbrances created by Tenant shall attach to Tenant’s interest only. Landlord shall
have the right at all times to post and keep posted on the Premises any notice which it deems necessary for protection from such liens. Tenant shall not cause or permit any lien of mechanics or materialmen or others to be placed against the Project,
the Building or the Premises with respect to work or services claimed to have been performed for or materials claimed to have been furnished to Tenant or the Premises, and, in case of any such lien attaching or notice of any lien, Tenant shall cause
it to be immediately released and removed of record. If any such lien is not released and removed within five (5) business days after notice of such lien is delivered by Landlord to Tenant, then Landlord may, at its option, take all action
necessary to release and remove such lien, without any duty to investigate the validity thereof, and all sums, costs and expenses, including reasonable attorneys’ fees and costs, incurred by Landlord in connection with such lien shall be deemed
Additional Rent under this Lease and shall immediately be due and payable by Tenant.

destruction of any property, other loss, cost or expense resulting from any release, spill, leak or other contamination of the Premises, or any other property surrounding the Premises attributable to the presence of Hazardous Materials. Upon
Landlord’s request, Tenant shall also obtain (at Tenant’s sole cost and expense) environmental impairment liability insurance and environmental remediation liability insurance (in form and substance (including limits) acceptable to
Landlord). If, at any time it reasonably appears to Landlord that Tenant is not maintaining sufficient insurance or other means of financial capacity to enable Tenant to fulfill its obligations to Landlord hereunder, whether or not then accrued,
liquidated, conditional or contingent, Tenant shall procure and thereafter maintain in full force and effect such insurance or other form of financial assurance, with or from companies or persons and in form and substance reasonably acceptable to
Landlord, as Landlord may from time to time reasonably request. Without limiting the generality of the foregoing, all such environmental liability insurance shall specifically insure the performance by Tenant of the indemnity provisions set forth in
this Lease.

Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall: (i) name Landlord, and any other party it so specifies, as an additional insured; (ii) specifically cover the liability assumed by Tenant under

before the Lease Commencement Date and at least ten (10) days before the expiration dates thereof. If Tenant shall fail to procure such insurance, or to deliver such policies or certificate, within such time periods, Landlord may, at its
option, in addition to all of its other rights and remedies under this Lease, and without regard to any notice and 

  

					
		 		 	
		 	-16-	 	
		 		 	

 
cure periods set forth in Section 19.1, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord as Additional Rent within ten (10) days after
delivery of bills therefor. Landlord may from time to time ask Tenant to seek or obtain other coverages or higher limits or broader coverage for required coverages, including adjustments required by holders of indebtedness secured by the Project,
and Tenant shall then use its best efforts promptly to obtain the coverages or limits. 
 10.4 Subrogation. Landlord
and Tenant agree to have their respective insurance companies issuing property damage insurance waive any rights of subrogation that such companies may have against Landlord or Tenant, as the case may be. Landlord and Tenant hereby waive any right
that either may have against the other on account of any loss or damage to their respective property to the extent such loss or damage is insurable under policies of insurance for fire and all risk coverage, theft, public liability, or other similar
insurance. 
 10.5 Additional Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at
Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10, and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and
Tenant’s operations therein, as may be reasonably requested by Landlord. 
 ARTICLE 11 

DAMAGE AND DESTRUCTION 

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises
resulting from fire or any other casualty. If the Premises or any common areas of the Building or Project serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to
reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the base, shell, and core of the Premises and such common areas. Such restoration shall
be to substantially the same condition of the base, shell, and core of the Premises and common areas prior to the casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the Project
and/or the Building, or the lessor of a ground or underlying lease with respect to the Building, or any other modifications to the common areas deemed desirable by Landlord, provided access to the Premises and any common restrooms serving the
Premises shall not be materially impaired. Upon the occurrence of any damage to the Premises, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required
under Section 10.3 of this Lease, and Landlord shall repair any damage to the tenant improvements and alterations installed in the Premises and shall return such tenant improvements and alterations to their original condition; provided that if
the costs of such repair of such tenant improvements and Alterations by Landlord exceeds the amount of insurance proceeds received by Landlord therefor from Tenant’s insurance carrier, as assigned by Tenant, the excess costs of such repairs
shall be paid by Tenant to Landlord prior to Landlord’s repair of the damage. In connection with such repairs and replacements of any such tenant improvements and Alterations, Tenant shall, prior to Landlord’s commencement of such
improvement work, submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto, and Landlord shall select the contractors to perform such improvement work. Landlord shall not be liable
for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or
common areas necessary to Tenant’s occupancy, and if such damage is not the result of the negligence or willful misconduct of Tenant or Tenant’s employees, contractors, licensees, or invitees, Landlord shall allow Tenant a proportionate
abatement of Base Rent and Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs to the extent Landlord is reimbursed from the proceeds of rental interruption insurance purchased by Landlord as part of Operating Expenses,
during the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result thereof. 

11.2 Landlord’s Option to Repair. Notwithstanding Section 11.1 above to the contrary, Landlord may elect not
to rebuild and/or restore the Premises, the Building and/or any other portion of the Project and instead terminate this Lease by notifying Tenant in writing of such termination within sixty (60) days after the date Landlord becomes aware of
such damage, such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only if the Building shall be damaged by fire or other casualty or cause, whether or not the Premises are
affected, and one or more of the following conditions is present: (i) repairs cannot reasonably be substantially completed within one hundred twenty (120) days after the date of such damage (when such repairs are made without the payment
of overtime or other premiums); (ii) the holder of any mortgage on the Project and/or the Building or ground or underlying lessor with respect to the Project and/or the Building shall require that the insurance proceeds or any portion thereof be
used to retire the mortgage debt, or shall terminate the ground or underlying lease, as the case may be; or (iii) the damage is not fully covered, except for deductible amounts, by Landlord’s insurance policies. In addition, if the
Premises or the Building is destroyed or damaged to any substantial extent during the last year of the Lease Term, then notwithstanding anything contained in this Article 11, Landlord shall have the option to terminate this Lease by giving written
notice to Tenant of the exercise of such option within thirty (30) days after such damage, in which event this Lease shall cease and terminate as of the date of such notice. Upon any such termination of this Lease pursuant to this
Section 11.2, Tenant shall pay the Base Rent and Additional Rent, properly apportioned up to such date of termination, and both parties hereto shall thereafter be discharged of all further obligations under this Lease, except for those
obligations which expressly survive the expiration or earlier termination of the Lease Term. 
 11.3 Waiver of Statutory
Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or any other
portion of the Project, and any statute or regulation of the state in which the 

  

					
		 		 	
		 	-17-	 	
		 		 	

 
Project is located, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the
absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or any other
portion of the Project. 
 ARTICLE 12 

CONDEMNATION 

12.1 Permanent Taking. If the whole or any part of the Premises, Building or Project shall be taken by power of eminent
domain or condemned by any competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use,
reconstruction or remodeling of any part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease
upon ninety (90) days’ notice, provided such notice is given no later than one hundred eighty (180) days after the date of such taking, condemnation, deed or other instrument. If more than twenty-five percent (25%) of the rentable
square feet of the Premises is taken, or if access to the Premises is substantially impaired. Tenant shall have the option to terminate this Lease upon ninety (90) days’ notice, provided such notice is given no later than one hundred
eighty (180) days after the date of such taking. Landlord shall be entitled to receive the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of
Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claim does not diminish the award available to
Landlord, or its ground lessor or mortgagee with respect to the Project, and such claim is payable separately to Tenant, All Rent shall be apportioned as of the date of such termination, or the date of such taking, whichever shall first occur. If
any part of the Premises shall be taken, and this Lease shall not be so terminated, the Base Rent and Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs shall be proportionately abated. Tenant hereby waives any and all
rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. 
 12.2
Temporary Taking. Notwithstanding anything to the contrary contained in this Article 12, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease
shall not terminate but the Base Rent and Tenant’s Share of Operating Expenses, Tax Expenses and Utilities Costs shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises
taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking. 

ARTICLE 13 
 COVENANT
OF QUIET ENJOYMENT 
 Landlord covenants that Tenant, on paying the Rent, charges for services and other payments
herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have,

 ARTICLE 14

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate,
encumber, or permit any lien to attach to. or otherwise transfer, this Lease or any interest hereunder, permit any assignment or other such foregoing transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any
part thereof, or permit the use of the Premises by any persons other than Tenant and its employees (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made
or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant shall desire Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer
Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a
description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer, the name and address of the proposed Transferee, and a copy of all existing and/or proposed
documentation pertaining to the proposed Transfer, (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, (v) a list of Hazardous Materials, certified by the proposed Transferee to
be true and correct, that the proposed Transferee intends to use or store in the Premises, and (vi) such other information as Landlord may reasonably require. Any Transfer made without Landlord’s prior written consent shall, at
Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or not Landlord shall grant consent, within thirty (30) days after written request by
Landlord, Tenant shall pay to Landlord Two Thousand Five Hundred Dollars ($2,500.00) to reimburse Landlord for its review and processing fees, and Tenant shall also reimburse Landlord for any reasonable legal fees incurred by Landlord in connection

		 	-18-	 	
		 		 	

 14.2 Landlord’s Consent. Landlord shall not unreasonably
withhold its consent to any proposed Transfer on the terms specified in the Transfer Notice. In no event shall Landlord be deemed to be unreasonable for declining to consent to a Transfer to a transferee jeopardizing directly or indirectly the
status of Landlord or any of Landlord’s affiliates as a Real Estate Investment Trust under the Internal Revenue Code of 1986 (as the same may be amended from time to time, the “Revenue Code”). Notwithstanding anything contained
in this Lease to the contrary, (w) no Transfer shall be consummated on any basis such that the rental or other amounts to be paid by the occupant, assignee, manager or other transferee thereunder would be based, in whole or in part, on the
income or profits derived by the business activities of such occupant, assignee, manager or other transferee; (x) Tenant shall not furnish or render any services to an occupant, assignee, manager or other transferee with respect to whom
transfer consideration is required to be paid, or manage or operate the Premises or any capital additions so transferred, with respect to which transfer consideration is being paid; (y) Tenant shall not consummate a Transfer with any person in
which Landlord owns an interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Revenue Code); and (z) Tenant shall not consummate a Transfer with any person or in any manner that
could cause any portion of the amounts received by Landlord pursuant to this Lease or any sublease, license or other arrangement for the right to use, occupy or possess any portion of the Premises to fail to qualify as “rents from real
property” within the meaning of Section 856(d) of the Revenue Code, or any similar or successor provision thereto or which could cause any other income of Landlord to fail to qualify as income described in Section 856(c)(2) of the
Revenue Code. The parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply, without limitation as to other
reasonable grounds for withholding consent: 
 14.2.1 The Transferee is of a character or reputation or engaged in a business
which is not consistent with the quality of the Building or Project; 
 14.2.2 The Transferee intends to use the Subject
Space for purposes which are not permitted under this Lease; 
 14.2.3 The Transferee is either a governmental agency or
instrumentality thereof; 
 14.2.4 The Transfer will result in more than a reasonable and safe number of occupants per floor
within the Subject Space; 
 14.2.5 The Transferee is not a party of reasonable financial worth and/or financial stability in
light of the responsibilities involved under the Lease on the date consent is requested; 
 14.2.6 The proposed Transfer
would cause Landlord to be in violation of another lease or agreement to which Landlord is a party, or would give an occupant of the Project a right to cancel its lease; 

14.2.7 The terms of the proposed Transfer will allow the Transferee to exercise a right of renewal, right of expansion, right
of first offer, or other similar right held by Tenant (or will allow the Transferee to occupy space leased by Tenant pursuant to any such right); or 

14.2.8 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is
under common control with, the proposed Transferee, (i) occupies space in the Project at the time of the request for consent, (ii) is negotiating with Landlord to lease space in the Project at such time, or (iii) has negotiated with
Landlord during the twelve (12)-month period immediately preceding the Transfer Notice. 
 If Landlord consents to any
Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 below), Tenant may within six (6) months after Landlord’s consent, enter into such Transfer of
the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 above, provided that if there are any changes in the terms and
conditions from those specified in the Transfer Notice (i) such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the proposed Transfer to be
more favorable to the Transferee than the terms set forth in Tenant’s original Transfer Notice, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of
recapture, if any, under Section 14.4 of this Lease). 
 14.3 Transfer Premium. If Landlord consents to a
Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any Transfer Premium received by Tenant from such Transferee. “Transfer Premium” shall mean all rent,
additional rent or other consideration payable by such Transferee in excess of the Rent and Additional Rent payable by Tenant under this Lease on a per rentable square foot basis if less than all of the Premises is transferred, after deducting the
reasonable expenses incurred by Tenant for (i) any reasonable changes, alterations and improvements to the Premises in connection with the Transfer (but only to the extent approved by Landlord), and (ii) any reasonable brokerage
commissions in connection with the Transfer (collectively, the “Subleasing Costs”). Transfer Premium shall also include, but not be limited to, key money and bonus money paid by Transferee to Tenant in connection with such Transfer,
and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. 

14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14,
Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any 

  

					
		 		 	
		 	-19-	 	
		 		 	

 
Transfer Notice, to recapture the Subject Space. Such recapture notice shall terminate this Lease with respect to the Subject Space as of the date stated in the Transfer Notice as the effective
date of the proposed Transfer until the last day of the term of the Transfer as set forth in the Transfer Notice. If this Lease is terminated with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of
the rentable square feet retained by Tenant in proportion to the rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the parties shall
execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner to recapture the Subject Space under this Section 14.4, then, provided Landlord has consented to the proposed Transfer, Tenant shall be
entitled to proceed to transfer the Subject Space to the proposed Transferee, subject to provisions of the last paragraph of Section 14.2 above. 

14.5 Effect of Transfer. If Landlord consents to a Transfer: (i) the terms and conditions of this Lease shall in no
way be deemed to have been waived or modified; (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee; (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed
copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord; and (iv) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall
relieve Tenant or any guarantor of the Lease from liability under this Lease. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and
shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency and Landlord’s costs of such audit. 

14.6 Additional Transfers. For purposes of this Lease, the term “Transfer” shall also include:
(i) if Tenant is a partnership or limited liability company, the withdrawal or change, voluntary, involuntary or by operation of law, of more than fifty percent (50%) of the partners or members, or transfer of more than fifty percent (50%) of
the partnership or membership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof; and (ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly held
and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant, (B) the sale or other transfer of more than an aggregate of fifty percent (50%) of the voting shares of
Tenant (other than to immediate family members by reason of gift or death), within a twelve (12) month period, or (C) the sale, mortgage, hypothecation or pledge of more than an aggregate of fifty percent (50%) of the value of the
unencumbered assets of Tenant within a twelve ( l2) month period. 
 ARTICLE 15 

SURRENDER; OWNERSHIP AND REMOVAL OF PERSONAL PROPERTY

shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in a writing signed by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of
Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at
any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the
option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises. 

15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of
this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant,

cleaning of any lab systems and sealing any connection points of any such lab systems to the Premises, all at Tenant’s sole cost and expense. At least one hundred twenty (120) days prior to Tenant’s surrender of possession of any part
of the Premises, Tenant shall provide Landlord with a facility decommissioning and Hazardous Materials closure plan for the Premises prepared by an independent third party reasonably acceptable to Landlord (“Surrender Plan”). Within
ten (10) days prior to Tenant’s surrender of possession of any part of the Premises, Tenant shall provide Landlord with written evidence that Tenant has fulfilled Tenant’s obligations set forth in the Surrender Plan and that Tenant
has obtained all appropriate governmental releases pertaining to the Premises in accordance with applicable laws, including laws pertaining to the surrender of the Premises (“Exit Survey”). In addition, Tenant agrees to remain
responsible after the surrender of the Premises for the remediation of any recognized environmental conditions set forth in the Surrender Plan and Exit Survey and compliance with any recommendations set forth in the Exit Survey. Tenant shall, upon
the expiration or earlier termination of this Lease, furnish to Landlord evidence that Tenant has closed all governmental permits and licenses, if any, issued in connection with Tenant’s or Tenant’s Parties’ activities at the
Premises. If any such governmental permits or licenses have been issued and Tenant fails to provide evidence of such closure on or before the expiration or earlier termination of this Lease, then until Tenant does so, the holdover provisions of
Article 16 of this Lease shall apply to the entire Premises. Upon such expiration or termination, Tenant shall, without expense to Landlord, satisfy any surrender obligations pursuant to Section 8.3 of this Lease and shall, in any event, remove
or cause to be removed from the Premises all telephone, data, and other cabling and wiring (including any cabling and wiring associated with the Wi-Fi Network, if any) installed or caused to be installed by

property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under 

  

					
		 		 	
		 	-20-	 	
		 		 	

 
Tenant, as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal.
Tenant’s obligations under this Section 15.2 shall survive the expiration or earlier termination of this Lease. 
 ARTICLE 16

 HOLDING OVER 

If Tenant holds over after the expiration of the Lease Term hereof, with or without the express or implied consent of
Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term, and in such case Base Rent
shall be payable at a monthly rate equal to one hundred fifty percent (150%) of the greater of (i) the Base Rent applicable during the last rental period of the Lease Term under this Lease, and (ii) the fair market rental rate of the
Premises as of the commencement of such holdover period. Such month-to-month tenancy shall be subject to every other term, covenant and agreement contained herein.
Landlord hereby expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be
deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to
Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of
the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender, and any lost profits to Landlord resulting therefrom. 

ARTICLE 17 
 ESTOPPEL
CERTIFICATES 
 Within ten (10) days following a request in writing by Landlord, Tenant shall execute and
deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be in the form as may be required by any prospective mortgagee or purchaser of the Project (or any portion thereof), indicating therein any exceptions thereto that
may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s Mortgagee or Landlords prospective mortgagees. Tenant shall execute and deliver whatever other instruments may be reasonably
required for such purposes. Failure of Tenant to timely execute and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel
certificate are true and correct, without exception. Failure by Tenant to so deliver such estoppel certificate shall be a material default of the provisions of this Lease. In addition, Tenant shall be liable to Landlord, and shall indemnify Landlord
from and against any loss, cost, damage or expense, incidental, consequential, or otherwise, including attorneys’ fees, arising or accruing directly or indirectly, from any failure of Tenant to execute or deliver to Landlord any such estoppel
certificate. Upon request from time to time, Tenant agrees to provide to Landlord, within twenty (20) days after Landlord’s delivery of written request therefor, current financial statements for Tenant, dated no earlier than one

executed in connection with this Lease, Tenant also agrees to deliver to Landlord, within twenty (20) days after Landlord’s delivery of written request therefor, current financial statements of the Guarantor in a form consistent with the
foregoing criteria.

allowing interest at the Interest Rate set forth in Section 4.5 above. As used in Section 19.2.1(iii) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal
Reserve Bank of San Francisco at the time of award plus one percent (1%). 
 19.2.2 Landlord shall have the remedy described
in California Civil Code Section 1951.4 (lessor may continue lease in effect after lessees breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations).
Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to
recover all rent as it becomes due. 
 19.2.3 Landlord may, but shall not be obligated to, make any such payment or perform
or otherwise cure any such obligation, provision, covenant or condition on Tenant’s part to be observed or performed (and may enter the Premises for such purposes). In the event of Tenant’s failure to perform any of its obligations or
covenants under this Lease, and such failure to perform poses a material risk of injury or harm to persons or damage to or loss of property, then 

  

					
		 		 	
		 	-22-	 	
		 		 	

 
Landlord shall have the right to cure or otherwise perform such covenant or obligation at any time after such failure to perform by Tenant, whether or not any such notice or cure period set forth
in Section 19.1 above has expired. Any such actions undertaken by Landlord pursuant to the foregoing provisions of this Section 19.2.3 shall not be deemed a waiver of Landlord’s rights and remedies as a result of Tenant’s failure
to perform and shall not release Tenant from any of its obligations under this Lease. 
 19.3 Payment by Tenant.
Tenant shall pay to Landlord, within ten (10) days after delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with Landlord’s
performance or cure of any of Tenant’s obligations pursuant to the provisions of Section 19.2.3 above; and (ii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent
or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all legal fees and other amounts so expended. Tenant’s obligations under this Section 19.3 shall survive
the expiration or sooner termination of the Lease Term. 
 19.4 Sublessees of Tenant. Whether or not Landlord elects
to terminate this Lease on account of any default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by
Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. If Landlord elects to succeed to Tenant’s interest in any such subleases,
licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder. 

19.5 Waiver of Default. No waiver by Landlord of any violation or breach by Tenant of any of the terms, provisions and
covenants herein contained shall be deemed or construed to constitute a waiver of any other or later violation or breach by Tenant of the same or any other of the terms, provisions, and covenants herein contained. Forbearance by Landlord in
enforcement of one or more of the remedies herein provided upon a default by Tenant shall not be deemed or construed to constitute a waiver of such default, The acceptance of any Rent hereunder by Landlord following the occurrence of any default,
whether or not known to Landlord, shall not be deemed a waiver of any such default, except only a default in the payment of the Rent so accepted. 

19.6 Efforts to Relet. For the purposes of this Article 19, Tenant’s right to possession shall not be deemed to
have been terminated by efforts of Landlord to relet the Premises, by its acts of maintenance or preservation with respect to the Premises, or by appointment of a receiver to protect Landlord’s interests hereunder. The foregoing enumeration is
not exhaustive, but merely illustrative of acts which may be performed by Landlord without terminating Tenant’s right to possession. 

ARTICLE 20 
 SECURITY
DEPOSIT 
 Concurrent with Tenant’s execution of this Lease, Tenant shall deposit with Landlord a security
deposit (the “Security Deposit”) in the amount set forth in Section 10 of the Summary. The Security Deposit 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. If Tenant defaults with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, Landlord may, but
shall not be required to, use, apply or retain all or any part of the Security Deposit for the payment of any Rent or any other sum in default, or for the payment of any amount that Landlord may spend or 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. If any portion of the Security Deposit is so used or applied, Tenant shall, within five (5) business days
after written demand therefor, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount, and Tenant’s failure to do so shall be a default under this Lease. If Tenant shall fully and faithfully
perform every provision of this Lease to be performed by it, the Security Deposit, or any balance thereof, shall be returned to Tenant, or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder, within thirty
(30) days following the expiration of the Lease Term. Tenant shall not be entitled to any interest on the Security Deposit. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, and all other provisions of
law, now or hereafter in force, which provide that Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by Tenant or to clean the Premises, it being agreed
that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or unforeseeable, caused by the act or omission of Tenant or any officer, employee, agent or invitee of Tenant.

 ARTICLE 21 

COMPLIANCE WITH LAW 

Tenant shall not do anything or suffer anything to be done in or about the Premises which will in any way conflict with any
law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated. At its sole cost and expense, Tenant shall promptly comply with all such governmental measures, other than
the making of structural changes or changes to the Building’s life safety system (collectively the “Excluded Changes”); provided, however, to the extent such Excluded Changes are required due to or triggered by Tenant’s
improvements or alterations to and/or manner of use of the Premises, Landlord shall perform such work, at Tenant’s cost (which shall be paid by Tenant to Landlord within ten (10) days after Tenant’s receipt of invoice therefor

  

					
		 		 	
		 	-23-	 	
		 		 	

 
from Landlord). In addition, Tenant shall fully comply with all present or future programs intended to manage parking, transportation or traffic in and around the Project, and in connection
therewith, Tenant shall take responsible action for the transportation planning and management of all employees located at the Premises by working directly with Landlord, any governmental transportation management organization or any other
transportation-related committees or entities. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said
governmental measures, shall be conclusive of that fact as between Landlord and Tenant.

the Premises. 
 ARTICLE 23

Torrey Ridge Science Center) specifically reserve the right to change the size, configuration, design, layout, location and all other aspects of the Parking Facility (including without limitation, implementing paid visitor parking), and Tenant
acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, close-off or restrict access to the Parking Facility.
Landlord may delegate its responsibilities hereunder to a parking operator (the “Parking Operator”) in which case the Parking Operator shall have all the rights of control attributed hereby to Landlord. Any parking tax or other
charges imposed by governmental authorities in connection with the use of such parking shall be paid directly by Tenant or the parking users, or, if directly imposed against Landlord, Tenant shall reimburse Landlord for all such taxes and/or charges
within ten (10) days after Landlord’s demand therefor. The parking rights provided to Tenant pursuant to this Article 23 are provided solely for use by Tenant’s own personnel and such rights may not be transferred, assigned, subleased
or otherwise alienated by Tenant without Landlord’s prior approval, except in connection with an assignment of this Lease or sublease of the Premises made in accordance with Article 14 above. All visitor parking by Tenant’s visitors shall

TENANT WORK LETTER 

This Tenant Work Letter (“Tenant Work Letter”) sets forth the terms and conditions relating to the
construction of improvements for the Premises. All references in this Tenant Work Letter to the “Lease” shall mean the relevant portions of the Lease to which this Tenant Work Letter is attached as Exhibit B. 

SECTION 1 

BASE, SHELL AND CORE 

Landlord has previously constructed the base, shell and core (i) of the Premises and (ii) of the floor(s) of the
Building on which the Premises are located (collectively, the “Base, Shell and Core”), and Tenant shall accept the Base, Shell and Core in its current “As-Is” condition existing as
of the date of the Lease and the Lease Commencement Date. Except as otherwise provided below, Landlord shall not be obligated to make or pay for any alterations or improvements to the Premises, the Building or the Project. 

SECTION 2 

CONSTRUCTION DRAWINGS FOR THE PREMISES 

Prior to the execution of the Lease, Landlord and Tenant have approved a detailed space plan for the construction of certain
improvements in the Premises, (the “Final Space Plan”), which Final Space Plan is dated January 14, 2016 and was prepared by DGA; such Final Space Plan is attached hereto as Schedule “I”. Based upon and in conformity
with the Final Space Plan, Landlord shall cause its architect and engineers to prepare and deliver to Tenant, for Tenant’s approval, detailed specifications and engineered working drawings for the tenant improvements shown on the Final Space
Plan (the “Working Drawings”). The Working Drawings shall incorporate modifications to the Final Space Plan as necessary to comply with the floor load and other structural and system requirements of the Building. To the extent that
the finishes and specifications are not completely set forth in the Final Space Plan for any portion of the tenant improvements depicted thereon, the actual specifications and finish work shall be in accordance with the specifications for the
Building’s standard tenant improvement items, as determined by Landlord. Within three (3) business days after Tenant’s receipt of the Working Drawings, Tenant shall approve or disapprove the same, which approval shall not be
unreasonably withheld; provided, however, that Tenant may only disapprove the Working Drawings to the extent such Working Drawings are inconsistent with the Final Space Plan and only if Tenant delivers to Landlord, within such three
(3) business day period, specific changes proposed by Tenant which are consistent with the Final Space Plan and do not constitute changes which would result in any of the circumstances described in items (i) through (iv) hereinbelow. If
any such revisions are timely and properly proposed by Tenant, Landlord shall cause its architect and engineers to revise the Working Drawings to incorporate such revisions and submit the same for Tenant’s approval in accordance with the
foregoing provisions, and the parties shall follow the foregoing procedures for approving the Working Drawings until the same are finally approved by Landlord and Tenant. Upon Landlord’s and Tenant’s approval of the Working Drawings, the
same shall be known as the “Approved Working Drawings”. The tenant improvements shown on the Approved Working Drawings shall be referred to herein as the “Tenant Improvements”. Once the Approved Working Drawings
have been approved by Landlord and Tenant, Tenant shall make no changes, change orders or modifications thereto without the prior written consent of Landlord, which consent may be withheld in Landlord’s sole discretion if such change or
modification would: (i) delay the Substantial Completion of the Premises (as defined below); (ii) increase the costs of the design, permitting and construction of the Tenant Improvements above the costs of the design, permitting and
construction of those tenant improvements depicted in the Final Space Plan; (iii) be of a quality lower than the quality of the standard tenant improvement items for the Building; and/or (iv) require any changes to the Base, Shell and Core
or structural improvements or systems of the Building. The Final Space Plan, Working Drawings and Approved Working Drawings shall be collectively referred to herein as, the “Construction Drawings”. 

SECTION 3 

CONSTRUCTION AND PAYMENT FOR COSTS OF TENANT IMPROVEMENTS 

Landlord and Tenant hereby agree that Landlord shall, at Landlord’s expense (except as provided in this Section 3)
cause a general contractor designated by Landlord (the “Contractor”) to (i) obtain all applicable building permits for construction of the Tenant Improvements (collectively, the “Permits”), and
(ii) construct the Tenant Improvements as depicted on the Approved Working Drawings, in compliance with such building permits and all applicable laws in effect at the time of construction, and in good workmanlike manner; provided, however, if
(A) the Approved Working Drawings differ with respect to the quality and quantity of those tenant improvements depicted on the Final Space Plan, and/or (B) Tenant shall request any changes or substitutions to any of the Construction
Drawings, and such differences, changes and/or substitutions result in increased costs of the design, permitting and construction of the Tenant Improvements in excess of the costs of the design, permitting and construction of those tenant
improvements depicted on the Final Space Plan, then Tenant shall pay such excess costs (which shall include a Landlord’s supervision fee of five percent (5%) of such costs) to Landlord in cash within ten (10) days after Landlord’s
request therefor. Notwithstanding the foregoing to the contrary, in no event shall Landlord be obligated to pay for the costs of any of Tenant’s furniture, computer systems, telephone systems, equipment or other personal property which may be
depicted on the Construction Drawings; the costs of such items shall be paid for by Tenant from Tenant’s own funds. 

  

					
		 	EXHIBIT B

 SECTION 4 

READY FOR OCCUPANCY; SUBSTANTIAL COMPLETION OF THE TENANT IMPROVEMENTS 

4.1 Ready for Occupancy; Substantial Completion. For purposes of the Lease, including for purposes of determining the
Lease Commencement Date (as set forth in Section 7.2 of the Summary); (i) the Premises shall be “Ready for Occupancy” upon Substantial Completion of the Premises; and (ii) “Substantial Completion of the
Premises” shall occur upon the completion of construction of the Tenant Improvements in the Premises pursuant to the Approved Working Drawings, with the exception of any punch list items that do not materially and adversely affect
Tenant’s use and occupancy of the Premises and any tenant fixtures, work-stations, built-in furniture, or equipment to be installed by Tenant or under the supervision of the Contractor. 

4.2 Delay of the Substantial Completion of the Premises. If there shall be a delay or there are delays in the
Substantial Completion of the Premises as a result of any of the following (collectively, “Tenant Delays”): 

4.2.1 Tenant’s failure to timely approve the Working Drawings or any other matter requiring Tenant’s approval; 

4.2.2 a breach by Tenant of the terms of this Tenant Work Letter or the Lease; 

4.2.3 Tenant’s request for changes in any of the Construction Drawings; 

4,2.4 Tenant’s requirement for materials, components, finishes or improvements which are not available in a commercially
reasonable time given the estimated date of Substantial Completion of the Premises, as set forth in the Lease, or which are different from, or not included in, Landlords standard tenant improvement items for the Building; 

4.2.5 changes to the Base. Shell and Core, structural components or structural components or systems of the Building required
by the Approved Working Drawings; 
 4.2.6 any changes in the Construction Drawings and/or the Tenant Improvements required
by applicable laws if such changes are directly attributable to Tenant’s use of the Premises or Tenant’s specialized tenant improvement(s) (as determined by Landlord); or 

4.2.7 any other acts or omissions of Tenant, or its agents, or employees; 

then, notwithstanding anything to the contrary set forth in the Lease and regardless of the actual date of Substantial Completion of the
Premises, the Lease Commencement Date (as set forth in Section 7.2 of the Summary) shall be deemed to be the date the Lease Commencement Date would have occurred if no Tenant Delays, as set forth above, had occurred. 

SECTION 5 

MISCELLANEOUS 

5.1 Tenant’s Entry Into the Premises Prior to Substantial Completion. Subject to the terms hereof and provided
that Tenant and its agents do not materially interfere with the Contractor’s work in the Project, the Building and the Premises, at Landlord’s reasonable discretion, Tenant shall have access to the Premises prior to the anticipated
Substantial Completion of the Premises for the purpose of Tenant inspecting the Contractor’s work and installing equipment and/or fixtures (including Tenant’s data and telephone equipment) and Tenant’s furniture in the Premises. Prior
to Tenant’s entry into the Premises as permitted by the terms of this Section 5.1, Tenant shall submit a schedule to Landlord and the Contractor, for their approval, which schedule shall detail the timing and purpose of Tenant’s
entry. In connection with any such entry, Tenant acknowledges and agrees that Tenant’s employees, agents, contractors, consultants, workmen, mechanics, suppliers and invitees shall fully cooperate, work in harmony and not, in any manner,
interfere with Landlord or Landlord’s contractors (including the Contractor), agents or representatives in performing work in the Project, the Building and the Premises, or interfere with the general operation of the Building and/or the
Project. If at any time any such person representing Tenant shall not be cooperative or shall otherwise cause or threaten to cause any such disharmony or interference, including, without limitation, labor disharmony, and Tenant fails to immediately
institute and maintain corrective actions as directed by Landlord in writing, then Landlord may revoke Tenant’s entry rights upon twenty-four (24) hours’ prior written notice to Tenant. Tenant acknowledges and agrees that any such
entry into and occupancy of the Premises or any portion thereof by Tenant or any person or entity working for or on behalf of Tenant shall be deemed to be subject to all of the terms, covenants, conditions and provisions of the Lease, excluding only
the covenant to pay Rent (until the occurrence of the Lease Commencement Date). Tenant further acknowledges and agrees that Landlord shall not be liable for any injury, loss or damage which may occur to any of Tenant’s work made in or about the
Premises in connection with such entry or to any property placed therein prior to the Lease Commencement Date, the same being at Tenant’s sole risk and liability. Tenant shall be liable to Landlord for any damage to any portion of the Premises,
including the Tenant Improvement work, caused by Tenant or any of Tenant’s employees, agents, contractors, consultants, workmen, mechanics, suppliers and invitees. If the performance of Tenant’s work in connection with such entry causes
extra costs to be incurred by Landlord or requires the use of any Building services, Tenant shall promptly reimburse Landlord for such extra costs and/or shall pay Landlord for such Building services at Landlord’s standard rates then in effect.
In addition, Tenant shall hold Landlord harmless from and indemnify, protect and defend Landlord against 

  

					
		 	EXHIBIT B	 	
		 	-2-	 	
		 		 	

 
any loss or damage to the Premises or Project and against injury to any persons caused by Tenant’s actions pursuant to this Section 5.1. 

5.2 Tenant’s Representative. Tenant has designated Peter Li as its sole representative with respect to the matters
set forth in this Tenant Work Letter, who shall have full authority and responsibility to act on behalf of the Tenant as required in this Tenant Work Letter, 

5.3 Landlord’s Representative. Landlord has designated Samantha Lagman as its sole representative with respect to
the matters set forth in this Tenant Work Letter, who, until further notice to Tenant, shall have full authority and responsibility to act on behalf of the Landlord as required in this Tenant Work Letter. 

5.4 Time of the Essence in This Tenant Work Letter. Unless otherwise indicated, all references herein to a “number
of days” shall mean and refer to calendar days. If any item requiring approval is timely disapproved by Landlord, the procedure for preparation of the document and approval thereof shall be repeated until the document is approved by Landlord.
Both Landlord and Tenant shall use commercially reasonable, good faith, efforts and all due diligence to cooperate with each other to complete all phases of the Construction Drawings and the permitting process and to receive the permits, as soon as
possible after the execution of the Lease, and, in that regard, shall meet on a scheduled basis to be determined by Landlord and Tenant, to discuss progress in connection with the same. 

5.5 Tenant’s Lease Default. Notwithstanding any provision to the contrary contained in the Lease, if an event of
default by Tenant of this Tenant Work Letter or the Lease has occurred at any time on or before the Substantial Completion of the Premises and remains after the expiration of applicable notice and cure periods, then (i) in addition to all other
rights and remedies granted to Landlord pursuant to the Lease, at law and/or in equity, Landlord shall have the right to cause the Contractor to suspend the construction of the Premises (in which case, Tenant shall be responsible for any delay in
the Substantial Completion of the Premises caused by such work stoppage as a Tenant Delay as set forth in Section 4.2 above), and (ii) all other obligations of Landlord under the terms of this Tenant Work Letter shall be forgiven until
such time as such default is cured pursuant to the terms of the Lease (in which case, Tenant shall be responsible for any delay in the Substantial Completion of the Premises caused by such inaction by Landlord as a Tenant Delay). In addition, if the
Lease is terminated prior to the Lease Commencement Date, for any reason due to a default by Tenant as described in Section 19.1 of the Lease or under this Tenant Work Letter, in addition to any other remedies available to Landlord under the
Lease, at law and/or in equity, Tenant shall pay to Landlord, as Additional Rent under the Lease, within five (5) business days after Tenant’s receipt of a statement therefor, any and all costs incurred by Landlord and not reimbursed or
otherwise paid by Tenant through the date of such termination in connection with the Tenant improvements to the extent planned, installed and/or constructed as of such date of termination, including, but not limited to, any costs related to the
removal of all or any portion of the Tenant Improvements and restoration costs related thereto.

other access codes or devices to all locks and/or security systems within and to the Premises. A reasonable number of keys to the locks on the entry doors of the Premises shall be furnished by Landlord to Tenant at Tenant’s cost, and Tenant

expense. 
 2. All doors opening to public corridors shall be kept closed at all times except for normal ingress and egress

Landlord from time to time; Tenant shall pay for the costs of all access cards provided to Tenant’s employees and all replacements thereof for lost, stolen and/or damaged cards. Access to the Building and/or the Project may be refused unless
the person seeking access has proper identification or has a previously arranged pass for such access. Landlord and its agents shall in no case be liable for damages for any error with regard to the admission to or exclusion from the Building and/or
the Project of any person. In case of invasion, mob, riot, public excitement, or other commotion, Landlord reserves the right to prevent access to the Building and/or the Project during the continuance of same by any means it deems appropriate for

such padding or take such other actions or prescribe such procedures as are appropriate to protect against damage to the elevators or other parts of the Building. Tenant shall assume all risk for damage to articles moved and injury to any persons
resulting from such activity described herein. If equipment, property, or personnel of Landlord or of any other party is damaged or injured as a result of or in connection with such activity described herein, Tenant shall be solely liable for any
resulting damage or loss. 
 6. Landlord shall have the right to control and operate the public portions of the Building and
Project, the public facilities, the heating and air conditioning, and any other facilities furnished for the common use of tenants, in such manner as is customary for comparable buildings in the vicinity of the Building.

14. No inflammable, explosive or dangerous fluids or substances shall be used or kept by Tenant in the Premises, Building
and/or about the Project, except for those substances as are typically found in similar premises used for general office purposes and are being used by Tenant in a safe manner and in accordance with all applicable Laws, rules and regulations. Tenant
shall not, without Landlord’s prior written consent, use, store, install, spill, remove, release or dispose of, within or about the Premises or any other portion of the Project, any asbestos-containing materials or any solid, liquid or gaseous
material now or subsequently considered toxic or hazardous under the provisions of 42 U.S.C. Section 9601 et seq. or any other applicable environmental Laws which may now or later be in effect. Tenant shall comply with all Laws pertaining to
and governing the use of these materials by Tenant, and shall remain solely liable for the costs of abatement and removal. 

15. Tenant shall not use, keep or permit to be used or kept, any foul or noxious gas or substance in or on the Premises, or

those having business therewith. 
 16. Tenant shall not bring into or keep within the Project, the Building or the Premises
any animals (except those assisting handicapped persons), birds, fish tanks, bicycles or other vehicles. 
 17. Tenant shall
not use or occupy the Premises in any manner or for any purpose which might injure the reputation or impair the present or future value of the Premises, the Building and/or the Project. Tenant shall not use, or permit any part of the Premises to be
used, for lodging, sleeping or for any illegal purpose. 
 18. No cooking shall be done or permitted by Tenant on the
Premises, nor shall the Premises be used for the storage of merchandise or for any improper, objectionable or immoral purposes. Notwithstanding the foregoing, Underwriters’ laboratory-approved equipment and microwave ovens may be used in the
Premises for heating food and brewing coffee, tea, hot chocolate and similar beverages, provided that such use is in accordance with all applicable federal, state and city laws, codes, ordinances, rules and regulations, and does not cause odors
which are objectionable to Landlord and other tenants.

wires and other cabling are to be introduced to the Premises. No boring or cutting for wires shall be allowed without the consent of Landlord. The location of telephone, call boxes and other office equipment and/or systems affixed to the Premises
shall be subject to the approval of Landlord. Tenant shall not use more than its proportionate share of telephone lines and other telecommunication facilities available to service the Building. 

20. Landlord reserves the right to exclude or expel from the Building and/or the Project any person who, in the judgment of

 EXHIBIT E 

INSURANCE REQUIRED OF CONTRACTORS 

1. Required Insurance. Contractor shall maintain the following insurance without interruption through final completion,
at any time thereafter when Contractor enters the site to perform work, and during any additional periods specified herein: 

(a) Commercial general liability insurance on the current ISO CG 00 01 occurrence form or an equivalent acceptable to
Owner (the “CGL”), [look at the following, grammatically] (i) covering liability arising from premises operations, independent contractors, products-completed operations, personal and advertising injury, and liability assumed
under an insured contract (including the tort liability of another assumed in a business contract), (ii) with limits of not less than $1,000,000 each occurrence, $1,000,000 personal and advertising injury, $2,000,000 general aggregate, and a
separate $2,000,000 products-completed operations aggregate, (iii) including the Additional Insureds (as defined in Section 6 of this Exhibit) as additional insureds, using one or more additional insured endorsements (such as a combination
of CG 20 10 (or CG 20 15 for vendors) and CG 20 37) that provides coverage for both ongoing and completed operations and is acceptable to Owner, (iv) that applies as primary and non-contributing insurance
with respect to any other insurance or self-insurance program afforded to the Additional Insureds, (v) that provides that any general aggregate limit applies separately to the work on a “per project” basis, (vi) that does not
limit the scope of coverage for liability arising from “XCU” (explosion, collapse, or underground) hazards, and (vii) that includes a standard ISO separation of insureds provision or a substantially similar provision. Contractor shall
maintain its products-completed operations coverage for at least three years after substantial completion of the work or the earlier termination of the Lease. 

(b) Business automobile liability insurance to cover liability arising out of any auto (including owned, hired and non-owned autos), with a limit of not less than $1,000,000 each accident. Contractor waives all rights against the Additional Insureds for recovery of damages to the extent those damages are covered under its
business automobile liability insurance (and, if applicable, commercial excess or umbrella liability insurance). 
 (c)
Workers compensation and employers liability insurance, for all persons Contractor employs in carrying out any work. The workers compensation insurance must fulfill applicable statutory requirements. The employers liability insurance must
have limits of not less than $1,000,000 each accident for bodily injury by accident, $1,000,000 each employee for bodily injury by disease, and $1,000,000 policy limit for bodily injury by disease. Contractor waives all rights against Landlord for
recovery of damages covered by the workers compensation and employers liability insurance obtained by Contractor, and shall obtain an endorsement to allow this waiver. If Contractor uses borrowed employees (including employees from a temporary
employment agency) to perform work, it shall require the primary employer to provide an alternate employer endorsement showing Contractor in the schedule as the alternate employer. 

(d) Commercial excess or umbrella liability insurance with respect to Contractor’s CGL, business auto liability,
and employers liability insurance, with a limit of not less than $3,000,000 [*Adjust as appropriate*] each occurrence. This insurance must be “true follow form,” must include the Additional Insureds as additional insureds with respect to
Contractor’s CGL, must apply on a primary and noncontributing basis with respect to any other insurance or self-insurance program afforded to the Additional Insureds, and must provide that aggregate limits of liability apply separately with
respect to the work. 
 2. Insurance Carried by Subcontractors. Contractor shall by written agreement require each of
its subcontractors and consultants of every tier (“Subcontractors”) to maintain as if they were “Contractor” the insurance required in Section 1 (including naming the Additional Insureds as additional insureds), except that
for Subcontractors with a contract value of less than $50,000 that are performing minor and non-hazardous work Contractor may, in its reasonable business judgment, (a) permit auto insurance limits of not
less than $500,000 each accident, and (b) permit employers liability limits of not less than $500,000 per type of claim, (c) waive the requirement for a waiver of subrogation for workers compensation and employers liability insurance, and
(d) waive the requirement for commercial excess or umbrella liability insurance. 
 3. Design Services or
Design-Build Services. If any portion of the work includes any design services or design-build work, the entity or individual providing the design services shall provide professional liability insurance with a limit of not less than $1,000,000
each claim and $1,000,000 aggregate. This insurance must be retroactive to the date of the commencement of the design services, and must be maintained for three years after substantial completion of the work or the earlier termination of the Lease.

 4. General Requirements. Each insurance policy required under this Exhibit E (together with the other requirements
of this Exhibit E, the “Required Insurance”) must, unless otherwise agreed in writing by Landlord, be issued by reputable insurance carriers having a Best’s rating of at least A- VIII.
Each policy and certificate will be subject to reasonable approval by Landlord, and Contractor shall deliver to Landlord certified copies of policies within 15 days after Landlord’s request. Except as may be specifically provided in this
Agreement, the cost (including deductibles and self-insured retentions) of the Required Insurance, as well as the cost of any other insurance carried by Contractor with respect to the work, will be borne solely by Contractor, without additional
reimbursement by Landlord. By requiring the Required Insurance, Landlord does not represent that the required coverage and limits will be adequate to protect Contractor, and unless otherwise specifically provided in the Lease the required coverage
and limits will not limit Contractor’s other obligations under the Lease. 

  

					
		 	EXHIBIT E	 	
		 	-1-	 	
		 		 	

 5. Evidence of Insurance. Concurrently with the execution of the
Lease, and in any event before commencing work at the site, Contractor shall provide to Landlord (i) an insurance certificate evidencing the Required Insurance, and (ii) an endorsement to Contractor’s CGL adding the Additional
Insureds as additional insureds. Contractor shall ensure that Landlord is notified at least 30 days before the cancellation or non-renewal of any Required Insurance, or 10 days prior in the case of
cancellation due to non-payment. Contractor shall provide an updated certificate of insurance before the expiration of the term of any Required Insurance. Landlord’s failure to require Contractor to
provide evidence of Required Insurance, or Landlord’s acceptance of evidence that indicates insurance that fails to satisfy the requirements of this Exhibit E, will not constitute a waiver of those requirements. 

6. Additional Insureds. The “Additional Insureds” are as follows: all individuals and entities that have any
direct or indirect interest in Landlord; any holders of indebtedness secured by the Project; Tenant (if this is a build-out) and any entities that Landlord, per any other project-related agreement, is required
to list as an additional insured, and, with respect to each of the foregoing, its managers, officers, directors, employees, and agents. 

7. Risk of Loss; Property Insurance. Except to the extent a loss is covered by applicable insurance, Contractor bears
the risk of loss and damage to the work (including any materials incorporated or to be incorporated as part of the work) until the date when the work is completed. Contractor and its Subcontractors are responsible to carry, at their own expense,
property insurance covering the full replacement value of their machinery, tools, and equipment, and of work (including materials) until the risk of loss for Work passes to Landlord. To the fullest extent permitted by law Contractor hereby waives,
and shall require Subcontractors (including equipment lessors) to waive, all claims against Landlord, the other Additional Insureds, tenants at the Project, and Landlord’s separate contractors and consultants and their subcontractors and
subconsultants, for loss or damage to these items, regardless of the cause.

 RIDER 

EXTENSION OPTION RIDER 

This Extension Option Rider (“Extension Rider”) is attached to and made a part of the Lease by and between
Landlord and Tenant. The agreements set forth in this Extension Rider shall have the same force and effect as if set forth in the Lease. To the extent the terms of this Extension Rider are inconsistent with the terms of the Lease, the terms of this
Extension Rider shall control. 
 1. Extension Options. Landlord hereby grants Tenant one (1) option (the
“Extension Option”) to extend the Lease Term for a period of five (5) years (the “Option Term”), which option shall be exercisable only by written Exercise Notice (as defined below) delivered by Tenant to
Landlord as provided below. Upon the proper exercise of the Extension Option, the Lease Term shall be extended for the Option Term. Notwithstanding the foregoing, at Landlord’s option, in addition to any other remedies available to Landlord
under the Lease, at law or in equity, the Extension Option shall not be deemed properly exercised if as of the date of delivery of the Exercise Notice (as defined below) by Tenant: (i) Tenant has previously been in material default under the
Lease beyond all applicable notice and cure periods; and/or (ii) Landlord does not reasonably approve of Tenant’s then-existing financial condition and/or Landlord’s lender does not approve of the terms for the Option Term, including,
without limitation, the Option Rent (as those terms are defined below). The Extension Option is personal to the Original Tenant and may only be exercised by the Original Tenant (and not any assignee, sublessee or other transferee of Tenant’s
interest in the Lease) if the Original Tenant occupies the entire Premises as of the date of Tenant’s delivery of the Exercise Notice. 

2. Option Rent. The annual Base Rent payable by Tenant during the Option Term (the “Option Rent”) shall be
equal to the greater of: (i) the annual Base Rent payable by Tenant during the last year of the initial Lease Term; or (ii) the Fair Market Rental Rate for the Premises. As used herein, the “Fair Market Rental Rate” shall
mean the annual base rent at which tenants, as of the commencement of the Option Term, will be leasing non-sublease space comparable in size, location (including views) and quality to the Premises for a
comparable term as the Option Term, which comparable space is located in the Building, the Other Existing Buildings in the Project and in other comparable first-class biotechnology buildings in the Torrey Pines area of San Diego County, taking into
consideration all free rent and other out-of-pocket concessions generally being granted at such time for such comparable space for the Option Term (including, without
limitation, any tenant improvement allowance provided for such comparable space, with the amount of such tenant improvement allowance to be provided for the Premises during the Option Term to be determined after taking into account the age, quality
and layout of the tenant improvements in the Premises as of the commencement of the Option Term with consideration given to the fact that the improvements existing in the Premises are specifically suitable to Tenant). All other terms and conditions
of the Lease shall apply throughout the Option Term; however, Tenant shall, in no event, have the option to extend the Lease Term beyond the Option Term described in Section 1 above. 

3. Exercise of Option. The Extension Option shall be exercised by Tenant, if at all, only in the following manner:
(i) Tenant shall deliver written notice (“Interest Notice”) to Landlord not more than fifteen (15) months nor less than twelve (12) months prior to the expiration of the initial Lease Term stating that Tenant may be
interested in exercising the Extension Option; (ii) Landlord, after receipt of Tenant’s notice, shall deliver notice (the “Option Rent Notice”) to Tenant not less than ten (10) months prior to the expiration of the
initial Lease Term setting forth the Option Rent; and (iii) if Tenant wishes to exercise the Extension Option, Tenant shall, on or before the date (the “Exercise Date”) which is nine (9) months prior to the expiration of
the initial Lease Term, exercise the Extension Option by delivering written notice (“Exercise Notice”) thereof to Landlord. Tenant’s failure to deliver the Interest Notice or Exercise Notice on or before the applicable delivery
dates therefore specified hereinabove shall be deemed to constitute Tenant’s waiver of the Extension Option. 
 4.
Determination of Option Rent. Tenant shall have no right to object to the Option Rent provided by Landlord, and if Tenant disagrees with Landlord’s determination of the Option Rent but Landlord and Tenant are unable to resolve such
disagreement as to the Option Rent prior to the Exercise Date, then either (i) Tenant shall accept Landlord’s determination of the Option Rent by exercising the Extension Option by delivering Tenant’s Exercise Notice to Landlord on or
before the Exercise Date, or (ii) Tenant shall be deemed to have relinquished the Extension Option, in which event the Extension Option shall be null and void as of the Exercise Date, and Landlord and Tenant shall have no further liability to
the other under this Extension Rider.

 SECOND AMENDMENT TO LEASE 

THIS SECOND AMENDMENT TO LEASE (this “Second Amendment”) is made as of June 8th, 2018, by and between
ARE-SD REGION NO. 44, LLC, a Delaware limited liability company (“Landlord”), and TP THERAPEUTICS, INC., a Delaware corporation (“Tenant”). 

RECITALS 

A. Landlord and Tenant are now parties to that certain Office Lease dated as of January 19, 2016, as amended by
that certain First Amendment to Lease dated as of July 11, 2016 (the “Lease”). Pursuant to the Lease, Tenant leases certain premises consisting of approximately 8,727 rentable square feet (“Original Premises”)
on the second floor of that certain building located at 10628 Science Center Drive, San Diego, California (the “Building”). The Original Premises are more particularly described in the Lease. Capitalized terms used herein without
definition shall have the meanings defined for such terms in the Lease. 
 B. Landlord and Tenant desire, subject to
the terms and conditions set forth below, to amend the Lease to, among other things, expand the size of the Original Premises by adding that portion of the first floor of the Building consisting of approximately 9,302 rentable square feet, as shown
on Exhibit A attached to this Second Amendment (“Expansion Premises”). 
 NOW, THEREFORE, in
consideration of the foregoing Recitals, which are incorporated herein by this reference, the mutual promises and conditions contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Landlord and Tenant hereby agree as follows: 
  

	1.	 Expansion Premises. In addition to the Original Premises, commencing on the Expansion
Premises Commencement Date, Landlord leases to Tenant, and Tenant leases from Landlord, the Expansion Premises. 

  

	2.	 Delivery. Landlord shall use reasonable efforts to deliver (“Delivery”
or “Deliver”) the Expansion Premises to Tenant on or before the Target Expansion Premises Commencement Date (as defined below) with Landlord’s Work in the Expansion Premises Substantially Completed. If Landlord fails to timely
Deliver the Expansion Premises, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and the Lease and this Second Amendment shall not be void or voidable. Notwithstanding anything to the contrary contained herein, if
Landlord fails to Deliver the Expansion Premises to Tenant by the date that is 60 days after the Target Expansion Premises Commencement Date (as such date may be extended for Force Majeure events, the “Abatement Date”), then Base
Rent payable with respect to the Expansion Premises only shall be abated 1 day for each day after the Abatement Date (as such date may be amended for Force Majeure events) that Landlord fails to Deliver the Expansion Premises to Tenant. As used
herein, the terms “Landlord’s Work,” “Tenant Delays” and “Substantially Completed” shall have the meanings set forth for such terms in the work letter attached to this Second Amendment as
Exhibit B (“Second Amendment Work Letter”). 

 The “Expansion Premises
Commencement Date” shall be the earlier to occur of: (i) the date that Landlord delivers the Expansion Premises to Tenant, or (ii) the date that Landlord could have delivered the Expansion Premises to Tenant but for Tenant Delays.
The “Target Expansion Premises Commencement Date” shall be September 1, 2018. 
 For the period of 30
consecutive days after the Expansion Premises Commencement Date, Landlord shall, at its sole cost and expense (which shall not constitute an Operating Expense), be responsible for any repairs that are required to be made to the Building systems
(including HVAC, mechanical, electrical and plumbing) serving the Expansion Premises, unless Tenant, or any of Tenant’s assignees, sublessees, licensees, agents, servants, employees, invitees and contractors 

  
 1 

 (or any of Tenant’s assignees’, sublessees’ and/or
licensees’ respective agents, servants, employees, invitees and contractors), was responsible for the cause of such repair, in which case Tenant shall pay the cost of such repair. 

Except as set forth in the Second Amendment Work Letter: (i) Tenant shall accept the Expansion Premises in their condition
as of the Expansion Premises Commencement Date; (ii) Landlord shall have no obligation for any defects in the Expansion Premises; and (iii) Tenant’s taking possession of the Expansion Premises shall be conclusive evidence that Tenant
accepts the Expansion Premises and that the Expansion Premises were in good condition at the time possession was taken. 

Tenant agrees and acknowledges that, except as otherwise expressly set forth in this Second Amendment, neither Landlord nor any
agent of Landlord has made any representation or warranty with respect to the condition of all or any portion of the Expansion Premises, and/or the suitability of the Expansion Premises for the conduct of Tenant’s business, and Tenant waives
any implied warranty that the Expansion Premises are suitable for the Permitted Use.

	9.	 The Alexandria Amenities. 

a. Generally. ARE-SD Region No. 17, LLC, a Delaware limited
liability company (“The Alexandria Landlord”) has constructed certain amenities at the property owned by The Alexandria Landlord located at 10996 Torreyana Road, San Diego, California (“The Alexandria”), which, as
of the date of this Second Amendment, include, without limitation, shared conference facilities (“Shared Conference Facilities”), a fitness center and restaurant (collectively, the “Amenities”) for non-exclusive use by (a) Tenant, (b) other tenants of the Project, (c) Landlord, (d) the tenants of The Alexandria Landlord, (e) The Alexandria Landlord, (e) other affiliates of Landlord, The
Alexandria Landlord and Alexandria Real Estate Equities, Inc. (“ARE”), (f) the tenants of such other affiliates of Landlord, The Alexandria Landlord and ARE, and (g) any other parties permitted by The Alexandria Landlord
(collectively, “Users”). Landlord, The Alexandria Landlord, ARE, and all affiliates of Landlord, The Alexandria Landlord and ARE may be referred to collectively herein as the “ARE Parties.” Notwithstanding anything
to the contrary contained herein, Tenant acknowledges and agrees that The Alexandria Landlord shall have the right, at the sole discretion 

  
 3 

 
of The Alexandria Landlord, to not make the Amenities available for use by some or all currently contemplated Users (including Tenant). The Alexandria Landlord shall have the sole right to
determine all matters related to the Amenities including, without limitation, relating to the reconfiguration, relocation, modification or removal of any of the Amenities at The Alexandria and/or to revise, expand or discontinue any of the services
(if any) provided in connection with the Amenities. Tenant acknowledges and agrees that Landlord has not made any representations or warranties regarding the availability of the Amenities and that Tenant is not entering into this Second Amendment
relying on the continued availability of the Amenities to Tenant. 
 b. License. Commencing on the Expansion
Premises Commencement Date, and so long as The Alexandria and the Project continue to be owned by affiliates of ARE, Tenant shall have the non-exclusive right to the use of the available Amenities in common
with other Users pursuant to the terms of this Section 9. Tenant shall be entitled to 2.5 passes to the fitness center located at The Alexandria per 1,000 rentable square feet of the Expansion Premises for use by employees
of Tenant employed at the Premises. If any employee of Tenant to whom a fitness center pass has been issued ceases to be an employee of Tenant at the Premises or any employee to whom an access card (which does not include a fitness center pass) has
been issued ceases to be an employee of Tenant at the Premises, Tenant shall immediately upon such employee’s change in status collect such employee’s pass or access card, as applicable, and deliver it to Landlord along with written notice
of such employee’s change in status. 
 Commencing on the Expansion Premises Commencement Date, Tenant shall pay to
Landlord a monthly fixed fee equal to $0.18 per rentable square foot of the Expansion Premises per month (“Amenities Fee”), which Amenities Fee shall by payable on the first day of each month during the Term whether or not Tenant
elects to use any or all of the Amenities. The Amenities Fee shall be increased annually on each anniversary of the Expansion Premises Commencement Date by 3%. Notwithstanding anything to the contrary contained herein, if Tenant exercises its
Extension Option under the Lease, then commencing on the commencement date of the Option Term, in addition to the Amenities Fee payable with respect to the Expansion Premises, Tenant will commence paying an Amenities Fee with respect to the Original
Premises on a per rentable square foot basis equal to the Amenities Fee then payable by Tenant on a per rentable square foot basis with respect to the Original Premises (as adjusted pursuant to this paragraph). If all of the Amenities at The
Alexandria become materially unavailable for use by Tenant (for any reason other than a default by Tenant under the Lease or the default by Tenant of any agreement(s) relating to the use of the Amenities by Tenant) for a period in excess of 60
consecutive days, then, commencing on the date that the Amenities in their entirety become materially unavailable for use by Tenant and continuing for the period that the Amenities in their entirety remain materially unavailable for use by Tenant,
the Amenities Fee then-currently payable by Tenant shall be abated. 
 c. Shared Conference Facilities. Use by
Tenant of the Shared Conference Facilities and restaurant at The Alexandria shall be in common with other Users with scheduling procedures reasonably determined by The Alexandria Landlord or The Alexandria Landlord’s then designated event
operator (“Event Operator”). Tenant’s use of the Shared Conference Facilities shall be subject to the payment by Tenant to The Alexandria Landlord of a fee equal to The Alexandria Landlord’s quoted rates for the usage of
the Shared Conference Facilities in effect at the time of Tenant’s scheduling. Tenant’s use of the conference rooms in the Shared Conference Area shall be subject to availability and The Alexandria Landlord (or, if applicable, Event
Operator) reserves the right to exercise its reasonable discretion in the event of conflicting scheduling requests among Users. Tenant hereby acknowledges that (i) Biocom/San Diego, a California
non-profit corporation (“Biocom”) has the right to reserve the Shared Conference Facilities and any reservable dining area(s) included within the Amenities for up to 50% of the time that such
Shared Conference Facilities and reservable dining area(s) are available for use by Users each calendar month, and (ii) Illumina, Inc., a Delaware corporation, has the exclusive use of the main conference room within the Shared Conference
Facilities for up to 4 days per calendar month. 

  
 4 

 Tenant shall be required to use the food service operator designated by The
Alexandria Landlord at The Alexandria (the “Designated Food and Beverage Operator”) for any food and/or beverage service or catered events held by Tenant in the Shared Conference Facilities. As of the date of this Second Amendment,
the Designated Food and Beverage Operator is The Farmer and the Seahorse. The Alexandria Landlord has the right, in its sole and absolute discretion, to change the Designated Food and Beverage Operator at any time. Tenant may not use any vendors
other than the Designated Food and Beverage Operator nor may Tenant supply its own food and/or beverages in connection with any food and/or beverage service or catered events held by Tenant in the Shared Conference Facilities. If Landlord notifies
Tenant in writing that there is no Designated Food and Beverage operator, then Tenant may use a food operator selected by Tenant and reasonably acceptable to Landlord. 

Tenant shall, at Tenant’s sole cost and expense, (i) be responsible for the
set-up of the Shared Conference Facilities in connection with Tenant’s use (including, without limitation ensuring that Tenant has a sufficient number of chairs and tables and the appropriate equipment),
and (ii) surrender the Shared Conference Facilities after each time that Tenant uses the Shared Conference Facilities free of Tenant’s personal property, in substantially the same set up and same condition as received, and free of any
debris and trash. If Tenant fails to restore and surrender the Shared Conference Facilities as required by sub-section (ii) of the immediately preceding sentence, such failure shall constitute a
“Shared Facilities Default.” Each time that Landlord reasonably determines that Tenant has committed a Shared Facilities Default, Tenant shall be required to pay Landlord a penalty within 5 days after notice from Landlord of such
Shared Facilities Default. The penalty payable by Tenant in connection with the first Shared Facilities Default shall be $200. The penalty payable shall increase by $50 for each subsequent Shared Facilities Default (for the avoidance of doubt, the
penalty shall be $250 for the second Shared Facilities Default, shall be $300 for the third Shared Facilities Default, etc.). In addition to the foregoing, Tenant shall be responsible for reimbursing The Alexandria Landlord or Landlord, as
applicable, for all costs expended by The Alexandria Landlord or Landlord, as applicable, in repairing any damage to the Shared Conference Facilities, the Amenities, or The Alexandria caused by Tenant or any Tenant Related Party. The provisions of
this Section 9(c) shall survive the expiration or earlier termination of the Lease. 
 d.
Restaurant. Tenant’s employees that have been issued an access card to The Alexandria shall have the right, along with other Users, to access and use the restaurant located at The Alexandria. 

e. Rules and Regulations. Tenant shall be solely responsible for paying for any and all ancillary services (e.g.,
audio visual equipment) provided to Tenant, all food services operators and any other third party vendors providing services to Tenant at The Alexandria. Tenant shall use the Amenities (including, without limitation, the Shared Conference
Facilities) in compliance with all applicable laws and any rules and regulations imposed by The Alexandria Landlord or Landlord from time to time and in a manner that will not interfere with the rights of other Users. The use of Amenities other than
the Shared Conference Facilities by employees of Tenant shall be in accordance with the terms and conditions of the standard licenses, indemnification and waiver agreement required by The Alexandria Landlord or the operator of the Amenities to be
executed by all persons wishing to use such Amenities. Neither The Alexandria Landlord nor Landlord (nor, if applicable, any other affiliate of Landlord) shall have any liability or obligation for the breach of any rules or regulations by other
Users with respect to the Amenities. Tenant shall not make any alterations, additions, or improvements of any kind to the Shared Conference Facilities, the Amenities or The Alexandria. 

Tenant acknowledges and agrees that The Alexandria Landlord shall have the right at any time and from time to time to
reconfigure, relocate, modify or remove any of the Amenities at The Alexandria and/or to revise, expand or discontinue any of the services (if any) provided in connection with the Amenities. 

  
 5 

 f. Waiver of Liability and Indemnification. Tenant warrants
that it will use reasonable care to prevent damage to property and injury to persons while on The Alexandria. Tenant waives any claims it or any Tenant Parties may have against any ARE Parties relating to, arising out of or in connection with the
Amenities and any entry by Tenant and/or any Tenant Parties onto The Alexandria, and Tenant releases and exculpates all ARE Parties from any liability relating to, arising out of or in connection with the Amenities and any entry by Tenant and/or any
Tenant Parties onto The Alexandria. Tenant hereby agrees to indemnify, defend, and hold harmless the ARE Parties from any claim of damage to property or injury to person relating to, arising out of or in connection with (i) the use of the
Amenities by Tenant or any Tenant Parties, and (ii) any entry by Tenant and/or any Tenant Parties onto The Alexandria, except to the extent caused by the negligence or willful misconduct of ARE Parties. The provisions of this
Section 9(f) shall survive the expiration or earlier termination of the Lease. 
 g.
Insurance. As of the Expansion Premises Commencement Date, Tenant shall cause The Alexandria Landlord to be named as an additional insured under the commercial general liability policy of insurance that Tenant is required to maintain pursuant
to Section 10.3 of the Lease. 
  

	10.	 Early Cancellation Right. Section 2.2 of the Lease is
hereby deleted in its entirety and is null and void and of no further force or effect. 

  

	11.	 Extension Option. For the avoidance of doubt, Tenant shall continue to have the right
to extend the Term; provided that Tenant may only exercise its Extension Option with respect to the entire Premises. 

  

	12.	 Control Areas. Section 5.4 of the Lease is hereby deleted in
its entirety and replaced with the following: 

 “5.4 Control Areas. Tenant shall have the use
of 100% of the control area designated as control area 3 on Exhibit C attached hereto. For the avoidance of doubt, Tenant shall not have rights with respect to any other control areas at the Project.” 

 

	13.	 Door Improvements. Tenant shall be required to remove the Door Improvements (as defined
in the Second Amendment Work Letter) and restore the area of the Premises in which the Door Improvements are located to their condition prior to the construction of the Door Improvements on or before the Expiration Date (which the parties anticipate
will cost approximately $5,000); provided, however, that if Tenant elects to exercise its Extension Option, then following the expiration of the Option Term, Tenant shall not be required to remove or restore the Door Improvements.

  

	14.	 Emergency Generator. Tenant shall have the right, in common with other tenants, to use
the existing emergency generator located at the Building. All costs incurred by Landlord in connection with the emergency generator shall be included as part of Operating Expenses. Notwithstanding anything to the contrary contained in the Lease,
Landlord’s sole obligation for either providing an emergency generator or providing emergency back-up power to Tenant shall be to contract with a third party to maintain the Emergency Generator as per the
manufacturer’s standard maintenance guidelines. Landlord shall have no obligation to provide Tenant with an operational emergency generator or back-up power or to supervise, oversee or confirm that the
third party maintaining the Emergency Generator is maintaining the generator as per the manufacturer’s standard guidelines or otherwise. During any period of replacement, repair or maintenance of the Emergency Generator, when the Emergency
Generator is not operational, including any delays thereto due to the inability to obtain parts or replacement equipment, Landlord shall have no obligation to provide Tenant with an alternative back-up
generator or generators or alternative sources of back-up power. Tenant expressly acknowledges and agrees that Landlord does not guaranty that the Emergency Generator will be operational at all times or that
emergency power will be available to the Premises when needed. 

  
 6 

	15.	 Monument Sign. Tenant shall have the
non-exclusive right to display, at Landlord’s cost, Tenant’s name on the monument sign serving the Building (the “Monument Sign”). Tenant acknowledges and agrees that Tenant’s
signage on the Monument Sign, including, without limitation, the location, size, color and type, shall be subject to Landlord’s prior written approval, which shall not be unreasonably withheld, conditioned or delayed, and shall be consistent
with Landlord’s signage program at the Project and applicable laws. Tenant shall be responsible, at Tenant’s sole cost and expense, for the maintenance of Tenant’s signage on the Monument Sign, for the removal of Tenant’s signage
from the Monument Sign at the expiration or earlier termination of this Lease and for the repair of all damage resulting from such removal. 

  

	16.	 OFAC. Tenant and all beneficial owners of Tenant are currently (a) in compliance
with and shall at all times during the Term of the Lease remain in compliance with the regulations of the Office of Foreign Assets Control (“OFAC”) of the U.S. Department of Treasury and any statute, executive order, or regulation
relating thereto (collectively, the “OFAC Rules”), (b) not listed on, and shall not during the term of the Lease be listed on, the Specially Designated Nationals and Blocked Persons List, Foreign Sanctions Evaders List, or the
Sectoral Sanctions Identification List, which are all maintained by OFAC and/or on any other similar list maintained by OFAC or other governmental authority pursuant to any authorizing statute, executive order, or regulation, and (c) not a
person or entity with whom a U.S. person is prohibited from conducting business under the OFAC Rules. 

  

	17.	 California Accessibility Disclosure. For purposes of Section 1938(a) of the California Civil
Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project has not undergone inspection by a Certified Access Specialist (CASp). In addition, the following notice is hereby provided pursuant to Section 1938(e)
of the California Civil Code: “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 lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential
occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of 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.” In furtherance of and in connection with such notice: (i) Tenant, having read such notice and understanding Tenant’s right
to request and obtain a CASp inspection, hereby elects not to obtain such CASp inspection and forever waives its rights to obtain a CASp inspection with respect to the Premises, Building and/or Project to the extent permitted by Legal Requirements;
and (ii) if the waiver set forth in clause (i) hereinabove is not enforceable pursuant to Legal Requirements, then Landlord and Tenant hereby agree as follows (which constitutes the mutual agreement of the parties as to the matters
described in the last sentence of the foregoing notice): (A) Tenant shall have the one-time right to request for and obtain a CASp inspection, which request must be made, if at all, in a written notice
delivered by Tenant to Landlord; (B) any CASp inspection timely requested by Tenant shall be conducted (1) at a time mutually agreed to by Landlord and Tenant, (2) in a professional manner by a CASp designated by Landlord and without
any testing that would damage the Premises, Building or Project in any way, and (3) at Tenant’s sole cost and expense, including, without limitation, Tenant’s payment of the fee for such CASp inspection, the fee for any reports
prepared by the CASp in connection with such CASp inspection (collectively, the “CASp Reports”) and all other costs and expenses in connection therewith; (C) the CASp Reports shall be delivered by the CASp simultaneously to
Landlord and Tenant; (D) Tenant, at its sole cost and expense, shall be responsible for making any improvements, alterations, modifications and/or repairs to or within the Premises to correct violations of construction-related accessibility
standards including, without limitation, any violations disclosed by such CASp inspection; and (E) if such CASp inspection identifies any improvements, alterations, modifications and/or repairs necessary to correct violations of
construction-related accessibility standards relating to those items of the Building and Project located outside the Premises that are Landlord’s obligation to repair as set forth in the Lease, then Landlord shall perform such improvements,
alterations, modifications and/or repairs as and to the extent required by Legal 

  
 7 

	 	 
Requirements to correct such violations, and Tenant shall reimburse Landlord for the cost of such improvements, alterations, modifications and/or repairs within 10 business days after
Tenant’s receipt of an invoice therefor from Landlord. 

  

	18.	 Brokers. Landlord and Tenant each represents and warrants that it has not dealt with
any broker, agent or other person (collectively, “Broker”) in connection with the transaction reflected in this Second Amendment and that no Broker brought about this transaction, other than CBRE and Cushman & Wakefield.
Landlord and Tenant each hereby agrees to indemnify and hold the other harmless from and against any claims by any Broker, other than CBRE and Cushman & Wakefield, claiming a commission or other form of compensation by virtue of having
dealt with Tenant or Landlord, as applicable, with regard to this Second Amendment. Landlord shall be responsible for all commissions due to CBRE and Cushman & Wakefield arising out of the execution of this Second Amendment in accordance
with the terms of a separate written agreement between Landlord, on the one hand, and CBRE and Cushman & Wakefield, on the other hand. 

  

	19.	 Miscellaneous. 

a. This Second Amendment is the entire agreement between the parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous oral and written agreements and discussions. This Second Amendment may be amended only by an agreement in writing, signed by the parties hereto. 

b. This Second Amendment is binding upon and shall inure to the benefit of the parties hereto, and their respective
successors and assigns. 
 c. This Second Amendment may be executed in 2 or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature process complying with the U.S. federal ESIGN Act of
2000) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. Electronic signatures shall be deemed original signatures for purposes of this
Second Amendment and all matters related thereto, with such electronic signatures having the same legal effect as original signatures. 

d. Except as amended and/or modified by this Second Amendment, the Lease is hereby ratified and confirmed and all other
terms of the Lease shall remain in full force and effect, unaltered and unchanged by this Second Amendment. In the event of any conflict between the provisions of this Second Amendment and the provisions of the Lease, the provisions of this Second
Amendment shall prevail. Whether or not specifically amended by this Second Amendment, all of the terms and provisions of the Lease are hereby amended to the extent necessary to give effect to the purpose and intent of this Second Amendment.

delayed, and (ii) DGA shall be the architect (the “TI Architect”) for the Tenant Improvements. 
 2.
Tenant Improvements. 
 (a) Tenant Improvements Defined. As used herein, “Tenant Improvements”
shall mean all improvements to the Expansion Premises of a fixed and permanent nature as shown on the TI Construction Drawings, as defined in Section 2(c) below. Other than Landlord’s Work (as defined in
Section 3(a) below), Landlord shall not have any obligation whatsoever with respect to the finishing of the Expansion Premises for Tenant’s use and occupancy. Notwithstanding anything to the contrary contained in the
Lease, Tenant shall not be required to remove or restore the Tenant Improvements at the expiration or earlier termination of the Term, nor shall Tenant have the right to remove any of the Tenant Improvements at any time during the Term or upon the
expiration or earlier termination of the Lease Term except as part of Alterations approved by Landlord, in its sole and absolute discretion. 

(b) Tenant’s Space Plans. The schematic drawings and outline specifications attached to this Second Amendment Work
Letter as Schedule 1 (the “Space Plans”) have been approved by Landlord and Tenant. 

  
 B-1 

 (c) Working Drawings. Landlord shall cause the TI Architect to
prepare and deliver to Tenant for review and comment construction plans, specifications and drawings for the Tenant Improvements (“TI Construction Drawings”), which TI Construction Drawings shall be prepared substantially in
accordance with the Space Plans. Tenant shall be solely responsible for ensuring that the TI Construction Drawings reflect Tenant’s requirements for the Tenant Improvements. Tenant shall deliver its written comments on the TI Construction
Drawings to Landlord not later than 10 business days after Tenant’s receipt of the same; provided, however, that Tenant may not disapprove any matter that is consistent with the Space Plans without submitting a Change Request. Landlord and the
TI Architect shall consider all such comments in good faith and shall, within 10 business days after receipt, notify Tenant how Landlord proposes to respond to such comments, but Tenant’s review rights pursuant to the foregoing sentence shall
not delay the design or construction schedule for the Tenant Improvements. Any disputes in connection with such comments shall be resolved in accordance with Section 2(d) hereof. Provided that the design reflected in the TI
Construction Drawings is consistent with the Space Plans, Tenant shall approve the TI Construction Drawings submitted by Landlord, unless Tenant submits a Change Request. Once approved by Tenant, subject to the provisions of
Section 4 below, Landlord shall not materially modify the TI Construction Drawings except as may be reasonably required in connection with the issuance of the TI Permit (as defined in Section 3(b)
below). 
 (d) Approval and Completion. Upon any dispute regarding the design of the Tenant Improvements, which is not
settled within 10 business days after notice of such dispute is delivered by one party to the other, Landlord may make the final decision regarding the design of the Tenant Improvements provided that such final decision is consistent with the Space
Plans. Any changes to the TI Construction Drawings by Tenant shall be processed as provided in Section 4 hereof. 

3. Performance of Landlord’s Work. 

(a) Definition of Landlord’s Work. As used herein, “Landlord’s Work” shall mean (i) the
work of constructing the Tenant Improvements, (ii) the work of constructing the common area restroom improvements shown on Schedule 1 attached hereto, and (iii) the work of constructing a door separating the laboratory portion of
the Premises from the office portion of the Premises as shown on Schedule 2 attached hereto (the “Door Improvements”). 

(b) Commencement and Permitting. Landlord shall commence construction of the Tenant Improvements upon obtaining a
building permit (the “TI Permit”) authorizing the construction of the Tenant Improvements consistent with the TI Construction Drawings approved by Tenant. The cost of obtaining the TI Permit shall be payable by Landlord. Tenant
shall assist Landlord in obtaining the TI Permit. If any governmental authority having jurisdiction over the construction of Landlord’s Work or any portion thereof shall impose terms or conditions upon the construction thereof that:
(i) are inconsistent with Landlord’s obligations hereunder, (ii) increase the cost of constructing Landlord’s Work, or (iii) will materially delay the construction of Landlord’s Work, Landlord and Tenant shall
reasonably and in good faith seek means by which to mitigate or eliminate any such adverse terms and conditions. 
 (c)
Completion of Landlord’s Work. Landlord shall substantially complete or cause to be substantially completed Landlord’s Work in a good and workmanlike manner, in accordance with Legal Requirements and the TI Permit subject, in each
case, to Minor Variations and normal “punch list” items of a non-material nature that do not interfere with the use of the Expansion Premises and with a certificate or temporary certificate of
occupancy (or an equivalent approval having been issued) for the Expansion Premises permitting lawful occupancy of the Expansion Premises (but specifically excluding any permits, licenses or other governmental approvals required to be obtained in
connection with Tenant’s operations in the Expansion Premises) (“Substantial Completion” or “Substantially Complete”). Upon Substantial Completion of Landlord’s Work, Landlord shall require the TI
Architect and the general contractor to execute and deliver, for the benefit of Tenant and Landlord, a Certificate of Substantial Completion in the form of the American Institute of Architects (“AIA”) document G704. For purposes of
this Second Amendment Work Letter, “Minor Variations” shall mean any modifications reasonably required: (i) to comply with all applicable Legal Requirements and/or to obtain or to comply with any required permit (including the
TI Permit); (ii) to comply with any request by Tenant for modifications to Landlord’s Work; (iii) to comport with 

  
 B-2 

 
good design, engineering, and construction practices that are not material; or (iv) to make reasonable adjustments for field deviations or conditions encountered during the construction of
Landlord’s Work. 
 (d) Selection of Materials. Where more than one type of material or structure is indicated on
the TI Construction Drawings approved by Landlord and Tenant, the option will be selected at Landlord’s sole and absolute subjective discretion. As to all building materials and equipment that Landlord is obligated to supply under this Second
Amendment Work Letter, Landlord shall select the manufacturer thereof in its reasonable discretion. 
 (e) Delivery of the
Expansion Premises. When Landlord’s Work is Substantially Complete, subject to the remaining terms and provisions of this Section 3(e), Tenant shall accept the Expansion Premises. Tenant’s taking possession
and acceptance of the Expansion Premises shall not constitute a waiver of: (i) any warranty with respect to workmanship (including installation of equipment) or material (exclusive of equipment provided directly by manufacturers), (ii) any non-compliance of Landlord’s Work with applicable Legal Requirements, or (iii) any claim that Landlord’s Work was not completed substantially in accordance with the TI Construction Drawings (subject
to Minor Variations and such other changes as are permitted hereunder) (collectively, a “Construction Defect”). Tenant shall have one year after Substantial Completion within which to notify Landlord of any such Construction Defect
discovered by Tenant, and Landlord shall use reasonable efforts to remedy or cause the responsible contractor to remedy any such Construction Defect within 30 days thereafter. Notwithstanding the foregoing, Landlord shall not be in default under the
Lease if the applicable contractor, despite Landlord’s reasonable efforts, fails to remedy such Construction Defect within such 30-day period. If the contractor fails to remedy such Construction Defect
within such 30-day period, Landlord shall use reasonable efforts to remedy the Construction Defect within a reasonable period. 

Tenant shall be entitled to receive the benefit of all construction warranties and manufacturer’s equipment warranties relating to
equipment installed in the Expansion Premises. If requested by Tenant, Landlord shall attempt to obtain extended warranties from manufacturers and suppliers of such equipment, but the cost of any such extended warranties shall be borne solely by
Tenant. Landlord shall promptly undertake and use reasonable efforts to complete, or cause to be completed, all punch list items within 30 days after the Commencement Date. 

(f) Commencement Date Delay. Except as otherwise provided in the Lease, Delivery of the Expansion Premises shall occur
when Landlord’s Work in the Expansion Premises has been Substantially Completed, except to the extent that completion of Landlord’s Work in the Expansion premises shall have been actually delayed by any one or more of the following causes
(“Tenant Delay”): 
 (i) Tenant’s Representative was not available within 2 business
days to give or receive any Communication or to take any other action required to be taken by Tenant hereunder; 

(ii) Tenant’s request for Change Requests (as defined in Section 4(a) below)
whether or not any such Change Requests are actually performed; 
 (iii) Construction of any Change Requests;

 (iv) Tenant’s request for materials, finishes or installations (excluding those specifically
identified in the approved TI Construction Drawings) requiring unusually long lead times, provided that promptly after Landlord learns of such long lead times, Landlord informs Tenant in writing that the requested items will require unusually long
lead times; 
 (v) Tenant’s delay in reviewing, revising or approving plans and specifications beyond
the periods set forth herein; 

  
 B-3 

 (vi) Tenant’s delay in providing information critical
to the normal progression of the Project. Tenant shall provide such information as soon as reasonably possible, but in no event longer than one week after receipt of any request for such information from Landlord; 

(vii) Tenant’s delay in making payments to Landlord for Excess TI Costs (as defined in
Section 5(d) below); or 
 (viii) Any other act or omission by Tenant or any Tenant
Party (as defined in the Lease), or persons employed by any of such persons. 
 If Delivery is delayed for any of the foregoing reasons,
then Landlord shall cause the TI Architect to certify the date on which the Tenant Improvements would have been Substantially Completed but for such Tenant Delay and such certified date shall be the date of Delivery. 

4. Changes. Any changes requested by Tenant to the Tenant Improvements shall be requested and instituted in accordance
with the provisions of this Section 4 and shall be subject to the written approval of Landlord and the TI Architect, such approval not to be unreasonably withheld, conditioned or delayed. 

(a) Tenant’s Request For Changes. If Tenant shall request changes to the Tenant Improvements
(“Changes”), Tenant shall request such Changes by notifying Landlord in writing in substantially the same form as the AIA standard change order form (a “Change Request”), which Change Request shall detail the nature
and extent of any such Change. Such Change Request must be signed by Tenant’s Representative. Landlord shall, before proceeding with any Change, use commercially reasonable efforts to respond to Tenant as soon as is reasonably possible with an
estimate of: (i) the time it will take, and (ii) the architectural and engineering fees and costs that will be incurred, to analyze such Change Request (which costs shall be paid by Tenant to the extent actually incurred, whether or not
such change is implemented). Landlord shall thereafter submit to Tenant in writing, within 5 business days of receipt of the Change Request (or such longer period of time as is reasonably required depending on the extent of the Change Request), an
analysis of the additional cost or savings involved, including, without limitation, architectural and engineering costs and the period of time, if any, that the Change will extend the date on which Landlord’s Work will be Substantially
Complete. Any such delay in the completion of Landlord’s Work caused by a Change, including any suspension of Landlord’s Work while any such Change is being evaluated and/or designed, shall be Tenant Delay. 

(b) Implementation of Changes. If Tenant: (i) approves in writing the cost or savings and the estimated extension
in the time for completion of Landlord’s Work, if any, and (ii) deposits with Landlord any Excess TI Costs required in connection with such Change, Landlord shall cause the approved Change to be instituted. Notwithstanding any approval or
disapproval by Tenant of any estimate of the delay caused by such proposed Change, the TI Architect’s determination of the amount of Tenant Delay in connection with such Change shall be final and binding on Landlord and Tenant. 

5. Costs. 

(a) Cost of Tenant Improvements. Except as otherwise provided in this Work Letter, Landlord shall be responsible for the
payment of design, permits and construction costs in connection with the construction of the Tenant Improvements, including, without limitation, the cost of preparing the TI Construction Drawings and the Space Plans, all costs set forth in the
budget for the Tenant Improvements and Landlord’s out-of-pocket expenses (collectively, “TI Costs”). Notwithstanding anything to the contrary
contained herein, in no event shall Landlord be required to pay for the Door Improvements or the purchase of any furniture, personal property or other non-Building system materials or equipment, including, but
not limited to, Tenant’s voice or data cabling equipment. 
 (b) Excess TI Costs. Tenant acknowledges and agrees
that Landlord shall have no responsibility for any costs arising from or related to Tenant’s Changes to the Space Plan or to the TI 

  
 B-4 

 
Construction Drawings approved by Tenant and Landlord, the cost of the Door Improvements (which the parties anticipate will cost approximately $15,000), Tenant Delays and the cost of Changes
(collectively, “Excess TI Costs”). Tenant shall deliver to Landlord, 100% of the Excess TI Costs within 10 days after Landlord’s written invoice therefor following the Substantial Completion of the Tenant Improvements. If
Tenant fails to deliver any Excess TI Costs to Landlord within such 10-day period, Landlord shall have all of the rights and remedies set forth in the Lease for nonpayment of Rent (including, but not limited
to, the right to interest at the Default Rate and the right to assess a late charge). For purposes of any litigation instituted with regard to such amounts, those amounts will be deemed Rent under the Lease. Funds deposited by Tenant shall be
disbursed to pay Excess TI Costs. Notwithstanding anything to the contrary set forth in this Work Letter, Tenant shall be fully and solely liable for Excess TI Costs. 

6. Tenant Access. 

(a) Tenant’s Access Rights. Landlord hereby agrees to permit Tenant access, at Tenant’s sole risk and expense,
to the Expansion Premises (i) 30 days prior to the Expansion Premises Commencement Date to perform any work (“Tenant’s Work”) required by Tenant other than Landlord’s Work, provided that such Tenant’s Work is
coordinated with the TI Architect and the general contractor, and complies with the Lease and all other reasonable restrictions and conditions Landlord may impose, and (ii) prior to the completion of Landlord’s Work, to inspect and observe
work in process; all such access shall be during normal business hours or at such other times as are reasonably designated by Landlord. Any entry by Tenant shall comply with all established safety practices of Landlord’s contractor and Landlord
until completion of Landlord’s Work and acceptance thereof by Tenant. 
 (b) No Interference. Neither Tenant nor
any Tenant Party (as defined in the Lease) shall interfere with the performance of Landlord’s Work, nor with any inspections or issuance of final approvals by applicable governmental authorities, and upon any such interference, Landlord shall
have the right to exclude Tenant and any Tenant Party from the Expansion Premises until Substantial Completion of Landlord’s Work. 

(c) No Acceptance of Expansion Premises. The fact that Tenant may, with Landlord’s consent, enter into the
Expansion Premises prior to the date Landlord’s Work is Substantially Complete for the purpose of performing Tenant’s Work shall not be deemed an acceptance by Tenant of possession of the Expansion Premises, but in such event Tenant shall
defend with counsel reasonably acceptable by Landlord, indemnify and hold Landlord harmless from and against any loss of or damage to Tenant’s property, completed work, fixtures, equipment, materials or merchandise, and from liability for death
of, or injury to, any person, caused by the act or omission of Tenant or any Tenant Party. 
 7. Miscellaneous. 

(a) Consents. Whenever consent or approval of either party is required under this Second Amendment Work Letter, that
party shall not unreasonably withhold, condition or delay such consent or approval, unless expressly set forth herein to the contrary. 

(b) Modification. No modification, waiver or amendment of this Second Amendment Work Letter or of any of its conditions
or provisions shall be binding upon Landlord or Tenant unless in writing signed by Landlord and Tenant. 
 (c)
Default. Notwithstanding anything set forth herein or in the Lease to the contrary, Landlord shall not have any obligation to perform any work hereunder or to fund any portion of the TI Costs during any period that there is a Default by
Tenant under the Lease.
