 LEASE 
 THIS LEASE is made as of this 5th day of October, 2007, by and between Oyster Point Tech Center LLC, a Delaware limited liability company (hereinafter Called “Landlord”), and Monogram Biosciences, Inc., a Delaware corporation
(hereinafter called “Tenant”). 
 1. PREMISES. Landlord hereby leases to Tenant, and Tenant leases from
Landlord, the Premises, for the Term, at the rental, and upon all of the terms and conditions set forth in this Lease. The Premises is comprised of the building which is commonly known and designated as 347 Oyster Point Boulevard, South San
Francisco, CA (sometimes referred to herein as the “Building”) and is depicted on Exhibit A-3. The Premises comprises one hundred percent (100%) of the rentable area of the Building. The Building is part of the Project. The
Building is crosshatched on Exhibit A-2. Upon Landlord’s delivery of Early Possession (as provided in Section 3 hereof), Tenant shall perform Tenant’s Work (as defined in Exhibit B-1 hereto) for the Premises.
Tenant’s Work shall be performed in the manner described in Exhibit B-1 hereto. 
 Tenant shall lease the
Premises “as-is”, “with all faults”, and “without any representations or warranties”, subject to Landlord’s obligations to Tenant as provided in the Lease. Tenant agrees and warrants that it has investigated and
inspected the condition of the Premises and the suitability of same for Tenant’s purposes, and Tenant hereby waives and disclaims any objection to, cause of action based upon, or claim that its obligations hereunder should be reduced or limited
because of the condition of the Premises or the suitability of same for Tenant’s purposes. Tenant acknowledges that neither Landlord nor any agent or employee of Landlord has made any representations or warranty with respect to the Premises or
with respect to its suitability for the conduct of Tenant’s business and Tenant expressly warrants and represents that Tenant has relied solely on its own investigation and inspection of the Premises in its decision to enter into this Amendment
and to continue to let the Premises in its “as-is” condition. 
 NOTWITHSTANDING THE FOREGOING OR ANYTHING TO THE
CONTRARY CONTAINED HEREIN, THE OBLIGATIONS OF THE PARTIES UNDER THIS LEASE ARE EXPRESSLY CONDITIONED UPON AND SUBJECT TO THE EXISTING TENANT (AND ANY SUBTENANTS) IN THE PREMISES ENTERING INTO AN AGREEMENT TERMINATING ITS LEASE AND ALL SUBLEASES UPON
TERMS ACCEPTABLE TO LANDLORD IN ITS SOLE AND ABSOLUTE DISCRETION. LANDLORD HAS NOT CONFIRMED TO TENANT IN WRITING THAT SUCH TERMINATION AGREEMENT(S) HAVE BEEN ENTERED INTO BY OCTOBER 12, 2007, THEN EITHER PARTY MAY TERMINATE THIS LEASE UPON WRITTEN
NOTICE TO THE OTHER. 
 2. TERM. The Term of this Lease (“Term”) shall commence on the term commencement date
(“Term Commencement Date”) and continue in full force and effect until April 30, 2018 or until this Lease is terminated as otherwise provided herein. The Term Commencement Date shall be the earlier of (1) the date Tenant begins
using the Premises for any purpose other than for the purpose of performing Tenant’s Work and installing Tenant’s equipment, Fixtures, Trade Fixtures and furniture as provided in Section 3 of this Lease, or (2) May 1, 2008.
Within ten (10) days after requested by Landlord, Landlord and Tenant shall execute an amendment to this Lease stating and confirming the Term Commencement Date and Tenant’s acceptance of the Premises. 
 3. POSSESSION. Landlord shall permit Tenant, or Tenant’s agents, to enter the Premises (“Early Possession”) after the
existing tenant vacates the Premises in the condition required under the terms of its lease, for the purpose of performing Tenant’s Work and installing Tenant’s equipment, Fixtures, Trade Fixtures and furniture. The terms
“Fixture” or “Trade Fixture” as used herein shall be defined as anything attached in any manner to Landlord’s property, except that equipment shall not be deemed a Fixture merely because of the manner in which such equipment
is connected to the electrical supply of the Building. All portable, unattached items are Tenant’s property. Tenant and Landlord agree that Tenant does not own any Trade Fixtures in the Premises except those items listed in Exhibit B-3
or otherwise agreed to in a separate writing between Landlord and Tenant. Landlord owns all remaining Trade Fixtures. In connection with Tenant’s Early Possession, from and after the date on which Tenant or its agent first enters the Premises
therefor, all of the terms and conditions of this Lease (including, but not limited to, insurance and indemnity provisions) shall be applicable to Tenant’s occupancy save and except for the requirement to pay Base Rent and Basic Operating
Costs.

 4. USE. 
 A. General. Tenant shall use the Premises for the Permitted Use and for no other use or purpose. Tenant shall control
Tenant’s employees, agents, customers, visitors, invitees, licensees, contractors, assignees and subtenants (collectively, “Tenant’s Parties”) in such a manner that Tenant and Tenant’s Parties cumulatively do not exceed the
Parking Density at any time. Tenant and Tenant’s Parties shall have the nonexclusive right to use, in common with other parties occupying the Building or the Project, the parking areas and driveways of the Project subject to such rules and
regulations as Landlord may from time to time prescribe. 
 B. Limitations. Tenant shall not permit any
odors, smoke, dust, gas, substances, noise or vibrations to emanate from the Premises, nor take any action which would constitute a nuisance or would disturb, obstruct or endanger any other tenants of the Building or the Project or interfere with
their use of their respective premises. Storage outside the Premises of materials, vehicles or any other items is prohibited. Tenant shall not use or allow the Premises to be used for any improper or unlawful purpose, nor shall Tenant cause or
maintain or permit any nuisance in, on or about the Premises or the Project. Tenant shall not commit or suffer the commission of any waste in, on or about the Premises or the Project. Tenant shall not allow any sale by auction upon the Premises or
the Project, or place any loads upon the floors, walls or ceilings which endanger the structure, or place any harmful liquids in the drainage system of the Building or the Project. No waste, materials or refuse shall be dumped upon or permitted to
remain outside the Premises except in trash containers placed inside exterior enclosures designated for that purpose by Landlord. Landlord shall not be responsible to Tenant for the non-compliance by any other tenant or occupant of the Building or
the Project with any of the above-referenced rules or any other terms or provisions of such tenant’s or occupant’s lease or other contract. 
 C. Compliance with Regulations. By entering the Premises, Tenant accepts the Premises in the condition existing as of the date of such entry, subject to Landlord’s representations and
warranties set forth in this Lease and subject to all existing or future applicable municipal, state and federal and other governmental statutes, regulations, laws and ordinances, including zoning ordinances and regulations governing and relating to
the use, occupancy and possession of the Premises and the use, storage, generation and disposal of Hazardous Materials (hereinafter defined) in, on and under the Premises (collectively “Regulations”). Except for matters which occurred
prior to the Term Commencement Date and were not caused directly or indirectly by Tenant or by any of Tenant’s Parties, Tenant shall, at Tenant’s sole expense, strictly comply with all Regulations now in force or which may hereafter be in
force relating to the Premises and the use of the Premises and/or Tenant’s and Tenant’s Parties’ use, storage, generation of Hazardous Materials in, on and under the Premises. Tenant shall at its sole cost and expense obtain any and
all licenses or permits necessary for Tenant’s use of the Premises. Tenant shall promptly comply with the requirements of any board of fire underwriters or other similar body now or hereafter constituted. Tenant shall not do or permit anything
to be done in, on, or about the Premises or bring or keep anything which will in any way increase the rate of any insurance upon the Premises, the Building or the Project, or upon any contents therein or cause a cancellation of said insurance or
otherwise affect said insurance in any manner. Tenant shall indemnify, defend, protect and hold Landlord harmless from and against any loss, cost, expense, damage, attorneys’ fees or liability arising out of the failure of Tenant to comply with
any Regulation or comply with the requirements as set forth herein. Notwithstanding the foregoing or anything to the contrary contained in this Lease, Tenant shall not be responsible for compliance with any laws, codes, ordinances or other
governmental directives where such compliance is caused by Landlord’s failure to cause the Building Shell to be constructed in compliance with all then applicable laws. Landlord warrants that on the Commencement Date the Building Shell shall
comply with all laws, codes, ordinances, and other governmental requirements applicable to the Premises and/or the Project as of the date the building permit was issued. 
 D. Hazardous Materials. Tenant shall not cause, or allow any of Tenant’s Parties to cause, any Hazardous
Materials to be generated, stored, used, treated, removed, transported, handled and disposed of on or about the Premises, the Building or the Project without Landlord’s prior written approval, provided that, Tenant shall be permitted to use the

  

 2 

 
Disclosed Hazardous Materials in the ordinary course of its business subject to the conditions and requirements of this Lease. Landlord’s conditional
authorization of the Disclosed Hazardous Materials shall be strictly limited to the types and quantities described in Exhibit E, and shall not be construed as an authorization for Tenant to generate, store, use, treat, remove, transport,
handle or dispose of any additional quantities of Disclosed Hazardous Materials or any other Hazardous Materials in, on, about or under the Premises, Building or the Project. Tenant acknowledges that any change in the types or quantities or
Disclosed Hazardous Materials described in Exhibit E, or any material change in the means and methods of generating, storing, treating, removing, transporting, handling or disposing of such Disclosed Hazardous Materials, shall require the
prior written approval of Landlord in each instance. Tenant represents and warrants to Landlord that (a) prior to its use of Hazardous Materials on the Premises, it will have received or obtained issuance of, and will maintain in effect, all
permits, approvals, licenses, or other authorizations necessary for Tenant’s activities with respect to the Disclosed Hazardous Materials, and (b) Tenant has not been cited, fined, or otherwise found to be in violation of any governmental
requirement or tire, safety and insurance requirements or regulations applicable to any Disclosed Hazardous Materials or any other Hazardous Materials in any other leased premises. At least once during each twelve (12) month of the Lease Term,
Tenant shall provide Landlord with an inventory list describing the minimum and maximum quantities of each of the Disclosed Hazardous Materials generated, stored, used, treated, removed, transported, handled and disposed of on or about the Premises,
the Building or the Project the succeeding twelve (12) months, and a copy of its Hazardous Materials Management Plan (“HMMP”) in the form submitted by Tenant to the fire department. Tenant agrees to notify Landlord immediately if
Tenant receives notification or otherwise becomes aware of: (a) any threatened or actual release, spill or discharge of any Disclosed Hazardous Materials in, on, about or under the Premises, the Building or the Project, or (b) any
threatened or actual lien, action, or proceeding or notice that any Disclosed Hazardous Materials or any other Hazardous Materials is not being generated, stored, used, treated, removed, transported, placed, manufactured, handled, or disposed of in
strict compliance with any and all governmental requirements and regulations or applicable fire, safety or insurance requirements and regulations. If Tenant or any of Tenant’s Parties is partially or wholly responsible or potentially
responsible for such condition, situation, lien, action or notice, Tenant’s notice to Landlord shall include a statement as to the actions Tenant proposes to take in response to such condition, situation, lien, action or notice. As used in this
Lease, “Hazardous Materials” shall include, but not be limited to, hazardous, toxic and radioactive materials and those substances defined as “hazardous substances,” “hazardous materials,” “hazardous wastes,”
“toxic substances,” or other similar designations in any federal, state, or local law, regulation, or ordinance. Landlord shall have the right at all reasonable times to inspect the Premises and to conduct tests and investigations to
determine whether Tenant is in compliance with the foregoing provisions, the costs of all such inspections, tests and investigations to be borne by Tenant. Tenant shall indemnify, defend (by counsel selected by Landlord), protect and hold Landlord
harmless from and against all liabilities, losses, costs and expenses, demands, causes of action, claims or judgments directly or indirectly arising out of the use, generation, storage or disposal of Hazardous Materials by Tenant or any of
Tenant’s Parties, which indemnity shall include, without limitation, attorneys’ and consultants’ fees, the cost of any required or necessary repair, cleanup or detoxification, and the preparation of any closure or other required
plans, whether such action is required or necessary prior to or following the termination of this Lease. Neither the written consent by Landlord to the use, generation, storage or disposal of Hazardous Materials nor the strict compliance by Tenant
with all laws pertaining to Hazardous Materials shall excuse Tenant from Tenant’s obligation of indemnification pursuant to this Paragraph 4.D. Tenant’s obligations pursuant to the foregoing indemnity shall survive the termination of this
Lease. Notwithstanding anything to the contrary in this Lease, Landlord warrants that on the Commencement Date to the best of Landlord’s knowledge the Premises and the Project, and the land and groundwater thereunder, are free of contamination
in excess of allowable limits by any Hazardous Materials introduced by Landlord or its employees, officers, or directors or, except for substances and materials within allowable limits used in the ordinary course of construction by Landlord’s
contractors. In the event of any breach of the foregoing warranty, Landlord shall promptly rectify the same as its sole cost and expense and shall indemnify, defend, and hold Tenant harmless from and against any actual damages, liability, suits,
losses, claims, actions, costs or expenses (including attorneys’ and consultants’ fees and costs) suffered by Tenant in connection with any such breach.

regulations Landlord may from time to time prescribe in writing for the purpose of maintaining the proper care, cleanliness, safety, traffic flow and general order of the Premises, the Building, or the Project. Tenant shall cause Tenant’s
Parties to comply with all such rules and regulations. Landlord shall not be responsible to Tenant for the non-compliance by any other tenant or occupant of the Building or the Project with any of the rules and regulations. 
 6. RENT. 
 A. Base Rent. Base Rent for the Premises has been calculated on the basis of the rentable square feet of the Premises at the rates specified in the Basic Lease Information. Tenant’s obligation to pay Base Rent for

without deduction or offset whatsoever, at the address specified in the Basic Lease Information or to such other place as Landlord may from time to time designate in writing. Base Rent and Estimated Basic Operating Costs as defined in Paragraph 7.A.
for the first full month of the Term shall be paid by Tenant upon Tenant’s execution of this Lease. If the obligation for payment of Base Rent commences on other than the first day of a month, then Base Rent (calculated at the rate applicable
to the second full month of the Term) for the partial month shall be prorated on the basis of the actual number of days in the month. 
 C. Additional Rent. All monies other than Base Rent required to be paid by Tenant hereunder, including, but not limited to, the interest and late charges described in Paragraph 26.D., any monies
spent by. Landlord pursuant to Paragraph 29., and Tenant’s Proportionate Share of Basic Operating Costs, as specified in Paragraph 7. of this Lease, shall be considered additional rent (“Additional Rent”). “Rent” shall mean
Base Rent and Additional Rent. 
 7. BASIC OPERATING COST. 
 A. Basic Operating Cost. In addition to the Base Rent required to be paid hereunder, Tenant shall pay as Additional
Rent, Basic Operating Costs in the manner set forth below. The Basic Operating Costs shall be calculated on the basis of the rentable square feet of the Building and the Project. Landlord and Tenant agree that the Building for all purposes under
this Lease consists of approximately 39,780 rentable square feet and the Project for all purposes under this Lease consists of approximately 105,120 rentable square feet. The number of rental square feet shall be final, conclusive and controlling.
Tenant’s obligation to pay Basic Operating Costs with respect to the Building and the Project shall commence on the Term Commencement Date. Landlord shall account for each item of Basic Operating Costs attributable to the Building and the
Project, in a commercially reasonable and customary manner, and unless provided to the contrary in this Lease, Tenant shall pay the Basic Operating Costs, as set forth in the Basic Lease Information. “Basic Operating Costs” shall mean all
commercially reasonable and customary expenses and costs of every kind and nature which Landlord shall pay or become obligated to pay because of or in connection with the management, maintenance, preservation and operation of the Building and the
Project (determined in accordance with generally accepted accounting principles, consistently applied) including but not limited to the following: 
 (1) Taxes. All real property taxes, possessory interest taxes, business or license taxes or fees, service payments in lieu of such taxes or fees, annual or periodic license or use fees, excises, transit
charges, housing fund assessments, open space charges, assessments, levies, fees or charges general and special, ordinary and extraordinary, unforeseen as well as foreseen, of any kind (including fees “in-lieu” of any such tax or
assessment) which are assessed, levied, charged, confirmed, or imposed by any public authority upon the Project, its operations or the Rent (or any portion or component thereof) (all of the foregoing being hereinafter collectively referred to as
“real property taxes”), or any tax imposed in substitution, partially or totally, of any tax previously included within the definition of real property taxes, or any additional tax the nature of which was previously included within the
definition of real property 

  

 4 

 
taxes, except (a) inheritance or estate taxes imposed upon or assessed against the Project, or any part thereof or interest therein, and (b) taxes
computed upon the basis of net income of Landlord or the owner of any interest therein, except as otherwise provided in the following sentence. Basic Operating Costs shall also include any taxes, assessments, or any other fees imposed by any public
authority upon or measured by the monthly rental or other charges payable hereunder, including, without limitation, any gross income tax or excise tax levied by the local governmental authority in which the Project is located, the federal
government, or any other governmental body with respect to receipt of such rental, or upon, with respect to or by reason of the development, possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of
the Premises or any portion thereof, or upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises. In the event that it shall not be lawful for Tenant to reimburse Landlord for
all or any part of such taxes, the Base Rent payable to Landlord under this Lease shall be revised to net to Landlord the same net rental after imposition of any such taxes on Landlord as would have been payable to Landlord prior to the payment of
any such taxes. 
 (2) Insurance. All insurance premiums and costs, including but not limited to, any deductible
amounts, premiums and costs of insurance incurred by Landlord, as more fully set forth in Paragraph 8.A. herein.

this Lease, repairs to the extent paid for by proceeds of insurance or by Tenant or other third parties, and alterations attributable solely to tenants of the Project other than Tenant). Such repairs, replacements, and general maintenance shall
include the cost of any capital improvements made to or capital assets acquired for the Project or the Building after the Term Commencement Date which reduce any other Basic Operating Cost but only to the extent of such reduction as reasonably
determined by Landlord, are reasonably necessary for the health and safety of the occupants of the Project, or are made to the Building by Landlord after the date of this Lease and are required under any governmental law or regulation, such costs or
allocable portions thereof to be amortized over the useful life thereof, together with interest on the unamortized balance at the “prime rate” charged at the time such improvements or capital assets are constructed or acquired by Wells
Fargo Bank, N.A. (San Francisco) plus two (2) percentage points, but in no event more than the maximum rate permitted by law. 
 (4) Services. To the extent such expenses are not the obligation of Tenant under other provisions of this Lease, all expenses relating to maintenance, janitorial and service agreements and services, and costs of supplies and
equipment used in operating and maintaining the Building and the Project and the equipment therein and the adjacent sidewalks, driveways, parking and service areas, including, without limitation, alarm service, window cleaning, elevator maintenance,
the Building exterior maintenance and Project landscaping. 
 (5) Utilities. To the extent such expenses are not
the obligation of Tenant under other provisions of this Lease, the cost of all utilities which benefit all or a portion of the Building or the Project. 
 (6) Management Fee. A management and accounting cost recovery fee equal to three (3%) percent of the sum of Base Rent and Basic Operating Cost. 
 (7) Legal and Accounting. Reasonable legal and accounting expenses relating to the Project, including the cost of audits by
certified public accountants. 
 In the event that the Building is not fully occupied during any fiscal year of the Term as
determined by Landlord, an adjustment shall be made in computing the Basic Operating Costs for such year so that Tenant pays an equitable portion of all variable items of Basic Operating Costs, as reasonably determined by Landlord; provided,
however, that in no event shall Landlord be entitled to collect in excess of one hundred (100%) percent of the total Basic Operating Costs from all of the tenants in the Building including Tenant.

specific tenants; the cost of redecorating or special cleaning or similar services to individual tenant spaces, not provided on a regular basis to other tenants of the

leasing commissions, finders fees and all other leasing expenses incurred in procuring tenants in the Building; any costs incurred in the ownership of the Building, as opposed to the operation and maintenance of the Building, including
Landlord’s income taxes, excess profit taxes, franchise taxes or similar taxes on Landlord’s business; preparation of income tax returns; corporation, partnership or other business form organization expenses; franchise taxes, filing fees;
or other such expenses; or any costs incurred in cleaning up any environment hazard or condition in violation of any environmental law (except to the extent caused by Tenant); legal fees for the negotiation or enforcement of leases; expenses in
connection with services or other benefits of a type which are not Building standard and which are provided to a single tenant of the Project; any items to the extent such items are required to be reimbursed to Landlord by Tenant (other than through
Tenant’s Additional Rent), or by other tenants or occupants of the Building or by third parties; the cost of constructing tenant improvements or installations for any tenant in the Project, including any relocation costs; brokerage commissions,
origination fees, points, mortgage recording taxes, title charges and other costs or fees incurred in connection with any financing or refinancing or transfer of the Building and/or any portion of the Project; attorneys’ fees and disbursements,
incurred in connection with the leasing of space in the project (including without limitation the enforcement of any lease or the surrender, termination or modification of any lease of space in the Project); advertising and promotional expenses,
brochures with respect to the Project; cost of repairs or replacements occasioned by fire, windstorm or other casualty, which are paid by insurance or reimbursed by governmental authorities in eminent domain; overhead and profit increment paid to
subsidiaries or affiliates of Landlord for services on or to the Project, to the extent that the costs of such services exceed market-based costs for such services rendered by unaffiliated persons or entities of similar skill, competence and
experience; penalties, fines, legal expenses, or late payment interest incurred by Landlord due to violation by Landlord or Landlord’s agents, contractors or employees, of either the payment terms and conditions of any lease or service contract
covering space in the Project or Landlord’s obligations as owner of the Building (such as late payment penalties and interest on real estate taxes, late payment of utility bills), except to the extent caused by Tenant’s failure to timely
pay or perform pursuant to this Lease; any compensation paid to clerks, attendants or other persons in any commercial concession operated by Landlord in the Project from which Landlord receives any form of income whatsoever, whether or not Landlord
actually makes a profit from such concession; or costs incurred in connection with correcting latent defects in any portion of the Building and/or Project or remediating Hazardous Materials contamination in the Building and/or Project, or in
repairing or replacing Building and/or Project equipment, where such repair or replacement results from original defects in design, manufacture or installation rather than from ordinary wear and tear or use. Notwithstanding anything herein to the
contrary, in any instance wherein Landlord, in Landlord’s sole discretion, deems Tenant to be responsible for any amounts greater than Tenant’s Proportionate Share, Landlord shall have the right to allocate costs in any manner Landlord
reasonably deems appropriate. 
 B. Payment of Estimated Basic Operating Cost. “Estimated Basic
Operating Costs” for any particular year shall mean Landlord’s estimate of the Basic Operating Cost for such fiscal year made prior to commencement of such fiscal year as hereinafter provided. Landlord shall have the right from time to
time to revise its fiscal year and interim accounting periods so long as the periods as so revised are reconciled with prior periods in accordance with generally accepted accounting principles applied in a consistent manner. During the last month of
each fiscal year during the Term, or as soon thereafter as practicable, Landlord shall give Tenant written notice of the Estimated Basic Operating Costs for the ensuing fiscal year. Tenant shall pay Tenant’s Proportionate Share of the Estimated
Basic Operating Cost with installments of Base Rent for the fiscal year to which the Estimated Basic Operating Cost applies in monthly installments on the first day of each calendar month during such year, in advance. If at any time during the
course of the fiscal year, Landlord determines that Basic Operating Cost is projected to vary from the then Estimated Basic Operating Cost by more than ten (10%) percent, Landlord may, by written notice to Tenant, revise the Estimated Basic
Operating Cost for the balance of such fiscal year, and Tenant’s monthly installments for the remainder of such year shall be adjusted so that by the end of such fiscal year Tenant has paid to Landlord Tenant’s Proportionate Share of the
revised Estimated Basic Operating Cost for such 

  

 6 

 
year. Upon execution of this Lease, Tenant shall pay to Landlord the Estimated Basic Operating Cost for the Premises (calculated on the estimated rentable
square feet) for the first full month of the Term. Upon final determination of the rentable square feet, Landlord and Tenant shall adjust such estimated payment. 
 C. Computation of Basic Operating Cost Adjustment. “Basic Operating Cost Adjustment” shall mean the
difference between Estimated Basic Operating Cost and Basic Operating Cost for any fiscal year determined as hereinafter provided. Within one hundred twenty (120) days after the end of each fiscal year, as determined by Landlord, or as soon
thereafter as practicable, Landlord shall deliver to Tenant a statement of Basic Operating Cost for the fiscal year just ended, accompanied by a computation of Basic Operating Cost Adjustment. If such statement shows that Tenant’s payment based
upon Estimated Basic Operating Cost is less than Tenant’s Proportionate Share of Basic Operating Cost, then Tenant shall pay to Landlord the difference within thirty (30) days after receipt of such statement. If such statement shows that
Tenant’s payments of Estimated Basic Operating Cost exceed Tenant’s Proportionate Share of Basic Operating Cost, then (provided that Tenant is not in Default under this Lease) Landlord shall credit the difference against the Estimated
Basic Operating Cost payment next due. If this Lease has been terminated or the Term hereof has expired prior to the date of such statement, then the Basic Operating Cost Adjustment shall be paid by the appropriate party within thirty (30) days
after the date of delivery of the statement and this obligation shall survive termination of the Lease. Should this Lease commence or terminate at any time other than the first day of the fiscal year, Tenant’s Proportionate Share of the Basic
Operating Cost adjustment shall be prorated by reference to the exact number of calendar days during such fiscal year that this Lease is in effect. 
 D. Net Lease. This shall be a net Lease and Base Rent shall be paid to Landlord net of all costs and expenses, except as specifically provided to the contrary in this Lease. The provisions for
payment of Basic Operating Cost and the Basic Operating Cost Adjustment are intended to pass on to Tenant and reimburse Landlord for all costs and expenses of the nature described in Paragraph 7.A. incurred in connection with the management,
maintenance, preservation and operation of the Building or the Project and such additional facilities now and in subsequent years as may be reasonably determined by Landlord to be necessary to the Building or the Project. 
 E. Tenant Audit. In the event that Tenant shall dispute the amount set forth in any statement provided by Landlord
under Paragraph 7.B. or 7.C. above, Tenant shall have the right, not later than sixty (60) days following the receipt of such statement and upon the condition that Tenant shall first deposit with Landlord the full amount in dispute within sixty
(60) days of receipt of such statement, to cause Landlord’s books and records with respect to Basic Operating Cost for such fiscal year to be audited by certified public accountants selected by Tenant and subject to Landlord’s
reasonable right of approval. The Basic Operating Cost Adjustment shall be appropriately adjusted on the basis of such audit. If such audit discloses a liability for a refund in excess of ten (10%) percent of Tenant’s Proportionate Share
of the Basic Operating Cost Adjustment previously reported, the cost of such audit shall be borne by Landlord; otherwise the cost of such audit shall be paid by Tenant. If Tenant shall not request an audit in accordance with the provisions of this
Paragraph 7.E. within sixty (60) days after receipt of Landlord’s statement provided pursuant to Paragraph 7.B. or 7.C., such statement shall be final and binding for all purposes hereof. 
 8. INSURANCE AND INDEMNIFICATION. 
 A. Landlord’s Insurance. Landlord agrees to maintain insurance insuring the Building against fire, lightning, vandalism and malicious mischief (including, if Landlord elects, “All
Risk” coverage, earthquake, and/or flood insurance), in an amount of not less than one hundred (100%) percent of the current replacement cost thereof, except where commercially unreasonable, with deductibles and the form and endorsements
of such coverage as selected by Landlord. Such insurance may also include, at Landlord’s option, insurance against loss of Base Rent and Additional Rent, in an amount equal to the amount of Base Rent and Additional Rent payable by Tenant for a
period of at least twelve (12) months commencing on the date of loss. Such insurance shall be for the sole benefit of Landlord and under Landlord’s sole control. Landlord shall not be obligated to insure any furniture, equipment,
machinery, goods or supplies which Tenant may keep or maintain in the Premises, or any leasehold improvements, additions or alterations within the Premises. Landlord may also carry such other insurance as Landlord may deem prudent or advisable,
including, without limitation, liability insurance in such amounts and on such terms as Landlord shall determine. 
  

 7 

 B. Tenant’s Insurance. 
 (1) Property Insurance. Tenant shall procure at Tenant’s sole cost and expense and keep in effect from the date of this
Lease and at all times until the end of the Term, insurance on all personal property, and Fixtures of Tenant and all improvements made by or for Tenant to the Premises, insuring such property for the full replacement value of such property.

 (2) Liability Insurance. Tenant shall procure at Tenant’s sole cost and expense and keep in effect from
the date of this Lease and at all times until the end of the Term either Comprehensive General Liability insurance or Commercial General Liability insurance applying to the use and occupancy of the Premises and the Building, and any part of either,
and any areas adjacent thereto, and the business operated by Tenant, or by any other occupant on the Premises. Such insurance shall include Broad Form Contractual Liability insurance coverage insuring all of Tenants indemnity obligations under this
Lease. Such coverage shall have a minimum combined single limit of liability of at least two million dollars ($2,000,000.00), and a general aggregate limit of five million dollars ($5,000,000.00). All such policies shall be written to apply to all
bodily injury, property damage or loss, personal injury and other covered loss, however occasioned, occurring during the policy term, shall be endorsed to add Landlord, Riggs Bank N.A., as trustee of Multi-Employer Trust, the Multi-Employer Trust,
Kennedy Associates Real Estate Counsel, Inc., and the officers, agents and employees of each of the foregoing entities, and any party holding an interest to which this Lease may be subordinated as an additional insured, and shall provide that such
coverage shall be primary and that any insurance maintained by Landlord shall be excess insurance only. Such coverage shall also contain endorsements: (i) deleting any employee exclusion on personal injury coverage; (ii) including
employees as additional insureds; (iii) deleting any liquor liability exclusion; and (iv) providing for coverage of employer’s automobile non-ownership liability. All such insurance shall provide for severability of interests; shall
provide that an act or omission of one of the named insureds shall not reduce or avoid coverage to the other named insureds; and shall afford coverage for all claims based on acts, omissions, injury and damage, which claims occurred or arose (or the
onset of which occurred or arose) in whole or in part during the policy period. Said coverage shall be written on an “occurrence” basis, if available. If an “occurrence” basis form is not available, Tenant must purchase
“tail” coverage for the most number of years available, and tenant must also purchase “tail” coverage if the retroactive date of an “occurrence” basis form is changed so as to leave a gap in coverage for occurrences
that might have occurred in prior years. If a “claims made” policy is ever used, the policy must be endorsed so that Landlord is given the right to purchase “tail” coverage should Tenant for any reason not do so or if the policy
is to be canceled for nonpayment of premium. 
 (3) General Insurance Requirements. All coverages described in
this Paragraph 8.B. shall be endorsed to provide Landlord with thirty (30) days’ notice of cancellation or change in terms. If at any time during the Term the amount or coverage of insurance which Tenant is required to carry under this
Paragraph 8.B. is, in Landlord’s reasonable judgment, materially less than the amount or type of insurance coverage typically carried by owners or tenants of properties located in the general area in which the Premises are located which are
similar to and operated for similar purposes as the Premises, Landlord shall have the right to require Tenant to increase the amount or change the types of insurance coverage required under this Paragraph 8.B. All insurance policies required to be
carried under this Lease shall be written by companies rated A+XII or better in “Best’s Insurance Guide” and authorized to do business in California. Any deductible amounts under any insurance policies required hereunder shall be
subject to Landlord’s prior written approval. In any event deductible amounts shall not exceed one thousand dollars ($1,000.00). Tenant shall deliver to Landlord on or before the Term Commencement Date, and thereafter at least thirty
(30) days before the expiration dates of the expiring policies, certified copies of Tenant’s insurance policies, or a certificate evidencing the same issued by the insurer thereunder, showing that all premiums have been paid for the full
policy period; and, in the event Tenant shall fail to procure such insurance, or to deliver such policies or certificates, Landlord may, at Landlord’s option and in addition to Landlord’s other remedies in the event of a Default by Tenant
hereunder, procure the same for the account of Tenant, and the cost thereof shall be paid to Landlord as Additional Rent. 
  

 8 

 C. Indemnification. Landlord shall not be liable to Tenant for any
loss or damage to person or property caused by theft, fire, acts of God, acts of a public enemy, riot, strike, insurrection, war, court order, requisition or order of governmental body or authority or for any damage or inconvenience which may arise
through repair or alteration of any part of the Building or the Project or failure to make any such repair, except as expressly otherwise provided in Paragraph 10. Tenant shall indemnify, defend by counsel acceptable to Landlord, protect and hold
Landlord harmless from and against any and all liabilities, losses, costs, damages, injuries or expenses, including reasonable attorneys’ fees and court costs, arising out of or related to: (1) claims of injury to or death of persons or
damage to property occurring or resulting directly or indirectly from the use or occupancy of the Premises, or from activities of Tenant, Tenant’s Parties or anyone in or about the Premises or Project, or from any cause whatsoever;
(2) claims for work or labor performed, or for materials or supplies furnished to or at the request of Tenant in connection with performance of any work done for the account of Tenant within the Premises or Project; and (3) claims arising
from any breach or Default on the part of Tenant in the performance of any covenant contained in this Lease. The foregoing indemnity shall not be applicable to claims arising from the gross negligence or willful misconduct of Landlord. The
provisions of this Paragraph shall survive the expiration or termination of this Lease with respect to any claims or liability occurring prior to such expiration or termination. 
 9. WAIVER OF SUBROGATION. To the extent permitted by law and without affecting the coverage provided by insurance to be maintained
hereunder, Landlord and Tenant each waive any right to recover against the other for: (a) damages for injury to or death of persons; (b) damages to property; (c) damages to the Premises or any part thereof, and (d) claims arising
by reason of the foregoing due to hazards covered by insurance to the extent of proceeds recovered therefrom. This provision is intended to waive fully, and for the benefit of each party, any rights and/or claims which might give rise to a right of
subrogation in favor of any Insurance carrier. The coverage obtained by each party pursuant to this Lease shall include, without limitation, a waiver of subrogation by the carrier which conforms to the provisions of this Paragraph. 
 10. LANDLORD’S REPAIRS. Landlord shall at Landlord’s expense maintain the structural soundness of the roof, the
foundations and exterior walls of the Building in good repair, reasonable wear and tear excepted; provided that, Landlord shall not be responsible for the cost of any repairs resulting from damage, destruction or deterioration which is caused by
Tenant, Tenant’s Parties, or by an act or event which is not fully insured. The term “exterior walls” as used herein shall not include windows, glass or plate glass, doors, special store fronts or office entries. Landlord shall
perform on behalf of Tenant and other tenants of the Project, as an item of Basic Operating Cost, the exterior maintenance of the Building, the Project, and public and common areas of the Project, including but not limited to the roof, pest
extermination, the landscaped areas, parking areas, driveways, the truck staging areas, fire sprinkler systems, sanitary and storm sewer lines, utility services, electric and telephone equipment servicing the Building(s), exterior lighting, and
anything which affects the operation and exterior appearance of the Project, which determination shall be at Landlord’s sole discretion. Except for the expenses directly involving the items specifically described in the first sentence of this
Paragraph 10., Tenant shall reimburse Landlord for all such costs in accordance with Paragraph 7. Any damage caused by or repairs necessitated by any act of Tenant or Tenant’s Parties may be repaired by Landlord at Landlord’s option and at
Tenant’s expense. Tenant shall immediately give Landlord written notice of any defect or need of repairs after which Landlord shall have a reasonable opportunity to repair same. Landlord’s liability with respect to any defects, repairs, or
maintenance for which Landlord is responsible under any of the provisions of this Lease shall be limited to the cost of such repairs or maintenance unless caused by Landlord’s gross negligence or willful misconduct. 
 11. TENANT’S REPAIRS. Tenant shall at Tenant’s expense throughout the Term of this Lease maintain all parts of the Premises in a
good, clean and secure condition and promptly make all necessary repairs and replacements, including but not limited to all windows, glass, doors, walls and wall finishes, floor covering, heating, ventilating and air conditioning systems, truck
doors, dock bumpers, dock plates and levelers, plumbing work and Fixtures, roof (exclusive of structural beams), downspouts, electrical and lighting systems, and fire sprinklers. Tenant shall at Tenant’s expense also perform regular removal of
trash and debris. Tenant shall, at Tenant’s own expense, enter into a regularly scheduled preventive maintenance/service contract with a maintenance contractor for servicing all hot water, heating and air conditioning 

  

 9 

 
systems and equipment within or serving the Premises. The maintenance contractor and the contract must be approved by Landlord which approval shall not be
unreasonably withheld or delayed. The service contract must include all services suggested by the equipment manufacturer within the operation/maintenance manual and must become effective and a copy thereof delivered to Landlord within thirty
(30) days after the Term Commencement Date. 
 12. ALTERATIONS. Tenant shall not make, or allow to be made, any
Alterations or physical additions in, about or to the Premises without obtaining the prior written consent of Landlord, which consent shall not be unreasonably withheld with respect to proposed alterations and additions which: (a) comply with
all applicable laws, ordinances, rules and regulations; (b) are in Landlord’s opinion, compatible with the Project and its mechanical, plumbing, electrical, heating/ventilation/air conditioning systems, (c) are constructed utilizing
Union Labor as set forth in Section 2.5 of Exhibit B-1; (d) will not interfere with the use and occupancy of any other portion of the Project by any other tenant or its invitees; (e) are performed promptly and in a workman like
manner; (f) the Project remains lien free as a result of the construction; and (g) are constructed using all new materials. Notwithstanding the foregoing, Tenant may, without the prior consent of Landlord, perform alterations which do not
in the aggregate cost more than (A) in the case of clinical laboratories, $200,000 per annum, and (B) in all other cases, $50,000 per annum provided that (i) Tenant gives Landlord not less than thirty (30) days prior written
notice thereof containing a description of the work to be performed and the estimated cost thereof, and (ii) the work to be performed does not impair the structural integrity of the Building, is not visible from the exterior of the Building,
and does not involve or affect any life safety or Building systems, and (iii) the work to be performed complies in all respects with the requirements of subsections (a), (c), (d), (e), (f) and (g) of this Section 12. The term
“Alteration” as used herein is defined as alterations, additions, substitutions, installations, changes and improvements, but excludes minor decorations. Specifically, but without limiting the generality of the foregoing, Landlord shall
have the right of written consent for all plans and specifications for the proposed Alterations or additions, construction means and methods, all appropriate permits and licenses, any contractor or subcontractor to be employed on the work of
Alteration or additions, and the time for performance of, such work. Tenant shall also supply to Landlord any documents and information reasonably requested by Landlord in connection with Landlord’s consideration of a request for approval
hereunder. Tenant shall reimburse Landlord for all costs which Landlord may reasonably incur in connection with granting approval to Tenant for any such Alterations and additions, including any costs or expenses which Landlord may reasonably incur
in electing to have outside architects and engineers review said plans and specifications. All such Alterations, physical additions or improvements shall remain the property of Tenant until termination of this Lease, at which time they shall be and
become the property of Landlord if Landlord so elects; provided, however, that Landlord may, at Landlord’s option, (provided that, at the time Landlord grants its consent to such Alterations, Landlord notifies Tenant in writing that removal
will be required), require that Tenant, at Tenant’s expense, remove any or all Alterations, additions, improvements and partitions made by Tenant and restore the Premises by the termination of this Lease, whether by lapse of time, or otherwise,
to their condition existing prior to the construction of any such alterations, additions, partitions or leasehold improvements. All such removals and restoration shall be accomplished in a good and workmanlike manner so as not to cause any damage to
the Premises or Project whatsoever. If Tenant fails to so remove such alterations, additions, improvements and partitions or Tenant’s Trade Fixtures or furniture, Landlord may keep and use them or remove any of them and cause them to be stored
or sold in accordance with applicable law, at Tenant’s sole expense. In addition to and wholly apart from Tenant’s obligation to pay Tenant’s Proportionate Share of Basic Operating Cost, Tenant shall be responsible for and shall pay
prior to delinquency any taxes or governmental service fees, possessory interest taxes, fees or charges in lieu of any such taxes, capital levies, or other charges imposed upon, levied with respect to or assessed against its personal property, on
the value of the alterations, additions or improvements within the Premises, and on Tenant’s interest pursuant to this Lease. To the extent that any such taxes are not separately assessed or billed to Tenant, Tenant shall pay the amount thereof
as invoiced to Tenant by Landlord. 
 13. SIGNS. All signs, notices, graphics and advertising balloons of every kind or
character, visible in or from public view or corridors, the common areas or the exterior of the Premises, shall be subject to Landlord’s prior written approval. Landlord shall provide, at Landlord’s cost, directional signage on the Project
identifying the location of the Building. Tenant shall not place or maintain any banners whatsoever or any window decor in or on any exterior window or window fronting upon any common areas or service area or upon any truck 

  

 10 

 
doors or man doors without Landlord’s prior written approval. Any installation of signs or graphics on or about the Premises and Project shall be
subject to any applicable governmental laws, CC&Rs, ordinances, regulations and to any other requirements imposed by Landlord. Tenant shall remove all such signs and graphics prior to the termination of this Lease. Such installations and
removals shall be made in such manner as to avoid injury or defacement of the Premises, the Building or the Project and any other improvements contained therein, and Tenant shall repair any injury or defacement, including without limitation,
discoloration caused by such installation or removal. 
 14. INSPECTION/POSTING NOTICES. After reasonable notice, except in
emergencies where no such notice shall be required, Landlord, and Landlord’s agents and representatives, shall have the right to enter the Premises to inspect the same, to clean, to perform such work as may be permitted or required hereunder,
to make repairs or alterations to the Premises or Project or to other tenant spaces therein, to deal with emergencies, to post such notices as may be permitted or required by law to prevent the perfection of liens against Landlord’s interest in
the Project or to exhibit the Premises to prospective tenants, purchasers, encumbrances or others, or for any other purpose as Landlord may deem necessary or desirable; provided, however, that Landlord shall use reasonable efforts not to
unreasonably interfere with Tenant’s business operations and shall not, except in the case of an emergency, enter areas of the Premises marked by Tenant as “sensitive” unless accompanied by Tenant’s representative which Tenant
shall make available to Landlord for such inspections. Tenant shall not be entitled to any abatement of Rent by reason of the exercise of any such right of entry. At any time within six (6) months prior to the end of the Term, Landlord shall
have the right to erect on the Premises and/or Project a suitable sign indicating that the Premises are available for lease. Tenant shall give written notice to Landlord at least thirty (30) days prior to vacating the Premises and shall meet
with Landlord for a joint inspection of the Premises at the time of vacating. In the event of Tenant’s failure to give such notice or participate in such joint inspection, Landlord’s inspection at or after Tenant’s vacating the
Premises shall conclusively be deemed correct for purposes of determining Tenant’s responsibility for repairs and restoration. 
 15.
UTILITIES. Tenant shall pay directly for all water, gas, heat, air conditioning, light, power, telephone, sewer, sprinkler charges and other utilities and services used on or from the Premises, together with any taxes, penalties,
surcharges or the like pertaining thereto, and maintenance charges for utilities and shall furnish all electric light bulbs, ballasts and tubes. If any such services are not separately metered to Tenant, Tenant shall pay a reasonable proportion, as
determined by Landlord, of all charges jointly serving other premises. Landlord shall not be liable for any damages (unless caused by Landlord’s gross negligence or willful misconduct) directly or indirectly resulting from nor shall the Rent or
any monies owed Landlord under this Lease herein reserved be abated by reason of: (a) the installation, use or interruption of use of any equipment used in connection with the furnishing of any such utilities or services; (b) the failure
to furnish or delay in furnishing any such utilities or services when such failure or delay is caused by acts of God or the elements, labor disturbances of any character, or any other accidents or other conditions beyond the reasonable control of
Landlord; or (6) the limitation, curtailment, rationing or restriction on use of water, electricity, gas or any other form of energy or any other service or utility whatsoever serving the Premises or Project. Landlord shall be entitled to
cooperate voluntarily and in a reasonable manner with the efforts of national, state or local governmental agencies or utility suppliers in reducing energy or other resource consumption. The obligation to make services available hereunder shall be
subject to the limitations of any such voluntary, reasonable program. 
 16. SUBORDINATION. Without the necessity of any
additional document being executed by Tenant for the purpose of effecting a subordination, this Lease shall be subject and subordinate at all times to all ground leases or underlying leases which may now exist or hereafter be executed affecting the
Premises and/or the land upon which the Premises and Project are situated, or both, provided any such subordination is conditioned upon Tenant’s receipt of a nondisturbance agreement in the lender’s customary form with respect to any
mortgage or deed of trust which may now exist or be placed upon said Project, land, ground leases or underlying leases, or Landlord’s interest or estate in any of said items which is specified as security. Notwithstanding the foregoing,
Landlord shall have the right to subordinate or cause to be subordinated any such ground leases or underlying leases or any such liens to this Lease. In the event that any ground lease or underlying lease terminates for any reason or any mortgage or
deed of trust is foreclosed or a conveyance in lieu of foreclosure is made for any reason, Tenant shall, notwithstanding any subordination, attorn to and become the Tenant of the successor in 

  

 11 

 
interest to Landlord at the option of such successor in interest. Within ten (10) days after request by Landlord, and conditioned upon Tenant’s
receipt of a nondisturbance agreement in the lender’s customary form, Tenant shall execute and deliver any additional documents evidencing Tenant’s attornment or the subordination of this Lease with respect to any such ground leases or
underlying leases or any such mortgage or deed of trust, in the form requested by Landlord or by any ground landlord, mortgagee, or beneficiary under a deed of trust. 
 17. FINANCIAL STATEMENTS. At the request of Landlord, Tenant shall provide to Landlord Tenant’s current financial statement or other information discussing financial worth of Tenant within thirty
(30) days after the date of Landlord’s request, which Landlord shall use solely for purposes of this Lease and in connection with the ownership, management and disposition of the Project. 
 18. ESTOPPEL CERTIFICATE. Tenant agrees from time to time, within ten (10) days after request of Landlord, to deliver to Landlord, or
Landlord’s designee, an estoppel certificate per Exhibit C or in an alternate form that the requesting party may require stating that this Lease is in full force and effect, the date to which Rent has been paid, the unexpired portion of
this Lease, and such other matters pertaining to this Lease as may be reasonably requested by Landlord. Landlord and Tenant intend that any statement delivered pursuant to this Paragraph may be relied upon by any mortgagee, beneficiary, purchaser or
prospective purchaser of the Project or any interest therein. The parties agree that Tenant’s obligation to furnish such estoppel certificates in a timely fashion is a material inducement for Landlord’s execution of the Lease, and shall be
an Event of Default if Tenant fails to fully comply. Tenant acknowledges that failure to provide the Estoppel Certificate to Landlord or Landlord’s designee within the time provided above may cause Landlord to incur substantial damages. Tenant
hereby agrees to indemnify Landlord for any liabilities, losses, costs, damages (including, without limitation, compensatory, incidental and consequential damages), injuries or expenses arising from the failure of Tenant to deliver the Estoppel
certificate in the time and manner provided in this Paragraph. In addition to any other remedies Landlord may have at law and equity, Landlord shall be entitled to specific performance of this Paragraph. The provisions of this Paragraph shall
survive the expiration or termination of this Lease with respect to any claims or liability occurring prior to such expiration or termination. Landlord shall execute (and acknowledge if required by any lender) and deliver to Tenant, within ten
(10) business days after Tenant provides such to Landlord, a statement in writing certifying that, to the best of Landlord’s actual knowledge this Lease is unmodified and in full force and effect (or, if modified, stating the nature of
such modification), the date to which the Base Rent and other charges are paid in advance, if any, and acknowledging that there are not, to Landlord’s actual knowledge, any uncured defaults on the part of Tenant hereunder or specifying such
defaults as are claimed. Landlord’s failure to deliver such statement within such time shall be conclusive upon the Landlord that (a) this Lease is in full force and effect, without modification except as may be represented by Tenant;
(b) there are no uncured defaults in Tenant’s performance; and (c) not more than one month’s Rent has been paid in advance. 
 19. SECURITY DEPOSIT. Tenant agrees to deposit with Landlord upon execution of this
Lease, a Security Deposit as stated in the Basic Lease Information, which sum shall be held by Landlord, without obligation for interest, as security for the performance of Tenant’s covenants and obligations under this Lease. The Security
Deposit is not an advance rental deposit or a measure of damages incurred by Landlord in case of Tenant’s Default. Landlord is not required to keep all or any part of the Security Deposit separate from its general accounts. Upon the occurrence
of any Event of Default by Tenant, Landlord may, from time to time, without prejudice to any other remedy provided herein or provided by law, use such fund to the extent necessary to make good any arrears of Rent or other payments due to Landlord
hereunder, and any other damage, injury, expense or liability caused by such Event of Default, and Tenant shall pay to Landlord, on demand, the amount so applied in order to restore the Security Deposit to its original amount. Although the Security
Deposit shall be deemed the property of Landlord, any remaining balance of such deposit shall be returned by Landlord to Tenant at such time after termination of this Lease that all of Tenant’s obligations under this Lease have been fulfilled.
Landlord may use and commingle the Security Deposit with other funds of Landlord. Provided that the Tenant is not then in default under the Lease or has not then committed an act or omission that would be an Event of Default with the passage of time
or the giving of notice, and provided further that during the preceding twelve (12) month period Tenant has not committed an Event of Default pursuant to the terms of this Lease, then commencing on the thirtieth (30th) month of the Lease Term, Landlord shall apply a maximum of one-half (1/2) of the Security 

  

 12 

 
Deposit as a credit against the Base Rent then coming due, such that after the application of one-half (1/2) of the Security Deposit to Base Rent, the
Security Deposit shall thereafter be the remaining one-half (1/2) of the original Security Deposit in the amount of $159,120.00. 
 20. TENANT’S REMEDIES. The liability of Landlord to Tenant for any default by Landlord under the terms of this Lease are not personal obligations of the Landlord or other trustees, advisors, partners, directors, officers
and shareholders of Landlord, and Tenant agrees to look solely to Landlord’s interest in the Project for the recovery of any amount from Landlord, and shall not look to other assets of Landlord nor seek recourse against the assets of the
Landlord or other trustees, advisors, partners, directors, officers and shareholders of Landlord. Any lien obtained to enforce any such judgment and any levy of execution thereon shall be subject and subordinate to any lien, mortgage or deed of
trust on the Project. 
 21. ASSIGNMENT AND SUBLETTING. 
 A. General. Except in connection with a Permitted Assignee, Tenant shall not assign this Lease or sublet the Premises
or any part thereof without Landlord’s prior written approval which shall not be unreasonably withheld or delayed. Except in connection with a Permitted Assignee, if Tenant desires to assign this Lease, or sublet any or all of the Premises, it
must present the Landlord with an ERISA Certificate in compliance with the provisions of Paragraph 37. of this Lease signed by the potential assignee or subtenant, demonstrate that the potential assignee or subtenant has adequate credit and
demonstrate to the Landlord’s satisfaction that the potential assignee’s or subtenant’s proposed use of the Premises is compatible with the Project and complies with all applicable laws, ordinances, rules and regulations. Except in
connection with a Permitted Assignee, if Tenant desires to assign this Lease or sublet any or all of the Premises, Tenant shall give Landlord written notice sixty (60) days prior to the anticipated effective date of the assignment or sublease.
Landlord shall then have a period of fifteen (15) days following receipt of such notice to notify Tenant in writing that Landlord elects either: (1) to permit Tenant to assign this Lease or sublet such space, subject, however, to
Landlord’s prior written approval of the proposed assignee or subtenant and of any related documents or agreements associated with the assignment or sublease or (2) refuse to consent. If Landlord should fail to notify Tenant in writing of
such election within said period, Landlord shall be deemed to have refused to consent to the proposed assignment or subletting. Without limiting the other instances in which it may be reasonable for Landlord to withhold Landlord’s consent to an
assignment or subletting, Landlord and Tenant acknowledge that it shall be reasonable for Landlord to withhold Landlord’s consent in the following instances: The use of the Premises by such proposed assignee or subtenant would not be a
permitted use or would increase the Parking Density of the Project; the proposed assignee or subtenant is not of sound financial condition, as reasonably determined by Landlord after receipt of the proposed assignee’s or subtenant’s
financial statements in form satisfactory to Landlord; the proposed assignee or subtenant is a governmental agency; the proposed assignee or subtenant does not have a good reputation as a tenant of property; the proposed assignee or subtenant is a
person with whom Landlord is negotiating to lease comparable space in the Project; the assignment or subletting would entail any alterations which would lessen the value of the leasehold improvements in the Premises; or if Tenant is in Default of
any obligation of Tenant under this Lease. Failure by Landlord to approve a proposed assignee or subtenant shall not cause a termination of this Lease. Notwithstanding anything in this Section 21A to the contrary, Tenant may, without the
consent of Landlord, assign this Lease or sublet the Premises or any portion thereof to any entity with a demonstrated net worth which is greater than $10,000,000 which (i) controls, is controlled by or is under common control with Tenant or
which (ii) results from a merger or reorganization or a consolidation with Tenant, or which (iii) acquires all of the stock or assets of Tenant, as a going concern, with respect to the business that is being conducted on the Premises
(“Permitted Assignees”). Any assignment or subletting to a Permitted Assignee shall be subject to and conditioned upon the following: (a) Tenant shall not be in Default of any of its obligations under this Lease, (b) Tenant shall
give Landlord at least sixty (60) days prior written notice of any such proposed transaction, (c) the Permitted Assignee shall have a net equity of at least Ten Million Dollars ($10,000,000) which has been demonstrated in appropriate
documentation delivered to Landlord prior to the occurrence of such transaction, (d) the Permitted Assignee shall execute an ERISA Certificate as set forth in Paragraph 37, and (e) Tenant shall provide Landlord with full and complete
copies of all documents executed by Tenant and the Permitted Assignee in connection with such assignment or subletting. The right to assign and/or sublet the Premises is personal to the Tenant and any Permitted Assignee and shall not inure to the
benefit of any other assignee, subtenant or successor of Tenant. 
  

 13 

 B. Bonus Rent. Any Rent or other consideration realized by Tenant
under any approved sublease or assignment in excess of the Base Rent payable hereunder, after amortization of a reasonable brokerage commission, reasonable attorneys’ fees related to the subletting, and the cost of tenant improvements, if any,
paid for by Tenant in excess of Tenant’s Work, shall be divided and paid, sixty (60%) percent to Tenant, forty (40%) percent to Landlord; provided, however, that if Tenant expends $70.00 per rentable square foot in excess of the
Tenant Improvement Allowance for Tenant’s Work, exclusive of soft costs, the aforesaid division shall be seventy-five percent (75%) to Tenant and twenty-five percent (25%) to Landlord. In any subletting or assignment undertaken by
Tenant, Tenant shall diligently seek to obtain the maximum rental amount available in the marketplace for such subletting or assignment. 
 C. Corporation. If Tenant is a corporation, a transfer of corporate shares by sale, assignment, bequest, inheritance, operation of law or other disposition (including such a transfer to or by a
receiver or trustee in federal or state bankruptcy, insolvency or other proceedings), so as to result in a change in the present control of such corporation or any of its parent corporations by the person or persons owning a majority of said
corporate shares, shall constitute an assignment for purposes of this Lease, provided, however, that this Section 21 C shall not apply to any transfer in connection with a bonafide financing or capitalization of Tenant, or if Tenant is or
becomes a public company. 
 D. Partnership. If Tenant is a partnership, joint venture or other
incorporated business form, a transfer of the interest of persons, firms or entities responsible for managerial control of Tenant by sale, assignment, bequest, inheritance, operation of law or other disposition, so as to result in a change in the
present control of said entity and/or a change in the identity of the persons responsible for the general credit obligations of said entity shall constitute an assignment for all purposes of this Lease, provided that this Section shall not apply to
a transfer in connection with a bonafide financing or capitalization of Tenant. 
 E. Liability. No
assignment or subletting by Tenant shall relieve Tenant of any obligation under this Lease. Any assignment or subletting which conflicts with the provisions hereof shall be void. 
 F. Options. Except in connection with a Permitted Assignee, in the event of assignment or subletting by Tenant, any
and all options to renew and expand shall terminate automatically. 
 22. AUTHORITY OF PARTIES. Landlord represents and
warrants that it has full right and authority to enter into this Lease and to perform all of Landlord’s obligations hereunder. Tenant represents and warrants that it has full right and authority to enter into this Lease and to perform all of
Tenant’s obligations hereunder. 
 23. CONDEMNATION. 
 A. Condemnation Resulting in Termination. If the whole or any substantial part of the Project of which the Premises
are a part should be taken or condemned for any public use under governmental law, ordinance or regulation, or by right of eminent domain, or by private purchase in lieu thereof, and the taking would prevent or materially interfere with the
Permitted Use of the Premises, this Lease shall terminate and the Rent shall be abated during the unexpired portion of this Lease, effective when the physical taking of said Premises shall have occurred. 
 B. Condemnation Not Resulting in Termination. If a portion of the Project of which the Premises are a part should be
taken or condemned for any public use under any governmental law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof, and this Lease is not terminated as provided in Paragraph 23.A. above, this Lease
shall not terminate, but the Rent payable hereunder during the unexpired portion of the Lease shall be reduced, beginning on the date when the physical taking shall have occurred, to such amount as may be fair and reasonable under all of the
circumstances. 
 C. Award. Landlord shall be entitled to any and all payment, income, rent, award, or
any interest therein whatsoever which may be paid or made in connection with such taking or conveyance and Tenant shall have no claim against Landlord or otherwise for the value of any unexpired portion of this Lease. Notwithstanding the foregoing,
any compensation specifically awarded Tenant for loss of business, Tenant’s personal property, moving costs or loss of goodwill, shall be and remain the property of Tenant. 
  

 14 

 24. CASUALTY DAMAGE. 
 A. General. If the Premises or the Building should be damaged or destroyed by fire, tornado, earthquake or other
casualty, Tenant shall give immediate written notice thereof to Landlord. Within thirty (30) days after Landlord’s receipt of such notice, Landlord shall notify Tenant whether in Landlord’s opinion such repairs can reasonably be made
either: (1) within ninety (90) days; (2) in more than ninety (90) days but in less than one hundred eighty (180) days; or (3) in more than one hundred eighty (180) days from the date of such notice. Landlord’s
determination shall be binding on Tenant. 
 B. Less Than 90 Days. If the Premises or the Building should
be damaged by fire, tornado, earthquake or other casualty but only to such extent that rebuilding or repairs can in Landlord’s estimation be reasonably completed within ninety (90) days after the date of such damage, this Lease shall not
terminate, and provided that insurance proceeds are available to fully repair the damage, Landlord shall proceed to rebuild and repair the Premises in the manner determined by Landlord, except that Landlord shall not be required to rebuild, repair
or replace any part of the partitions, Fixtures, additions and other leasehold improvements which may have been placed in, on or about the Premises. If the Premises are untenantable in whole or in part following such damage, the Rent payable
hereunder during the period in which they are untenantable shall be abated proportionately, but only to the extent of rental abatement insurance proceeds received by the Landlord during the time and to the extent the Premises are unfit for
occupancy. In the event that Landlord should fail to complete such repairs and rebuilding within one hundred eighty days (180) days after the date upon which Landlord is notified by Tenant of such damage, such period of time to be extended for
delays caused by the fault or neglect of Tenant or for delays (but not by more than forty-five (45) days for such delays) because of acts of God, acts of public agencies, labor disputes, strikes, fires, freight embargoes, rainy or stormy
weather, inability to obtain materials, supplies or fuels, or delays of the contractors or subcontractors or any other causes or contingencies beyond the reasonable control of Landlord, Tenant may at Tenant’s option within ten (10) days
after the expiration of such one hundred eighty (180) day period (as such may be extended), terminate this Lease by delivering written notice of termination to Landlord as Tenant’s exclusive remedy, whereupon all rights hereunder shall
cease and terminate thirty (30) days after Landlord’s receipt of such termination notice. 
 C. Greater
Than 90 Days. If the Premises or the Building should be damaged by fire, tornado, earthquake or other casualty but only to such extent that rebuilding or repairs can in Landlord’s estimation be reasonably completed in more than ninety
(90) days but in less than one hundred eighty (180) days, then Landlord shall have the option of either: (1) terminating the Lease effective upon the date of the occurrence of such damage, in which event the Rent shall be abated
during the unexpired portion of the Lease; or (2) electing to rebuild or repair the Premises to substantially the condition in which they existed prior to such damage, provided that insurance proceeds are available, to fully repair the damage,
except that Landlord shall not be required to rebuild, repair or replace any part of the partitions, Fixtures, additions and other improvements which may have been placed in, on or about the Premises. If the Premises are untenantable in whole or in
part following such damage, the Rent payable hereunder during the period in which they are untenantable shall be abated proportionately, but only to the extent of rental abatement insurance proceeds received by the Landlord during the time and to
the extent the Premises are unfit for occupancy. In the event that Landlord should fail to complete such repairs and rebuilding within one hundred eighty days (180) days after the date upon which Landlord is notified by Tenant of such damage,
such period of time to be extended for delays caused by the fault or neglect of Tenant or for delays (but not by more than forty-five (45) days for such delays) because of acts of God, acts of public agencies, labor disputes, strikes, fires,
freight embargoes, rainy or stormy weather, inability to obtain materials, supplies or fuels, or delays of the contractors or subcontractors or any other causes or contingencies beyond the reasonable control of Landlord, Tenant may at Tenant’s
option within ten (10) days after the expiration of such one hundred eighty (180) day period (as such may be extended), terminate this Lease by delivering written notice of termination to Landlord as Tenant’s exclusive remedy,
whereupon all rights hereunder shall cease and terminate thirty (30) days after Landlord’s receipt of such termination notice. 
  

 15 

 D. Greater Than 180 Days. If the Premises or the Building should be
so damaged by fire, tornado, earthquake or other casualty that rebuilding or repairs cannot in Landlord’s estimation be completed within one hundred eighty (180) days after such damage, this Lease shall terminate and the Rent shall be
abated during the unexpired portion of this Lease, effective upon the date of the occurrence of such damage. 
 E.
Tenant’s Fault. If the Premises or any other portion of the Building is damaged by fire or other casualty resulting from the fault, negligence, or breach of this Lease by Tenant or any of Tenant’s Parties, Base Rent and
Additional Rent shall not be diminished during the repair of such damage and Tenant shall be liable to Landlord for the cost and expense of the repair and restoration of the Building caused thereby to the extent such cost and expense is not covered
by insurance proceeds. 
 F. Uninsured Casualty. Notwithstanding anything herein to the contrary, in the
event that the Premises or the Building is damaged or destroyed and are not fully covered by the insurance proceeds received by Landlord or in the event that the holder of any indebtedness secured by a mortgage or deed of trust covering the Premises
requires that the insurance proceeds be applied to such indebtedness, then in either case Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within thirty (30) days after the date of
notice to Landlord that said damage or destruction is not fully covered by insurance or such requirement is made by any such holder, as the case may be, whereupon all rights and obligations hereunder shall cease and terminate. 
 G. Waiver. Except as otherwise provided in this Paragraph 24., Tenant hereby waives the provisions of Sections
1932(a), 1933(4), 1941 and 1942 of the Civil Code of California. 
 25. HOLDING OVER. If Tenant shall retain possession of the
Premises or any portion thereof without Landlord’s consent following the expiration of the Lease or sooner termination for any reason, then Tenant shall pay to Landlord for each day of such retention 150% of the amount of the daily rental as of
the last month prior to the date of expiration or termination. Tenant shall also indemnify, defend, protect and hold Landlord harmless from any loss, liability or cost, including reasonable attorneys’ fees, resulting from delay by Tenant in
surrendering the Premises, including, without limitation, any claims made by any succeeding tenant founded on such delay. Acceptance of Rent by Landlord following expiration or termination shall not constitute a renewal of this Lease, and nothing
contained in this Paragraph 25. shall waive Landlord’s right of reentry or any other right. Unless Landlord consents in writing to Tenant’s holding over, Tenant shall be only a Tenant at sufferance, whether or not Landlord accepts any Rent
from Tenant while Tenant is holding over without Landlord’s written consent. Additionally, in the event that upon termination of the Lease, Tenant has not fulfilled its obligation with respect to repairs and cleanup of the Premises or any other
Tenant obligations as set forth in this Lease, then Landlord shall have the right to perform any such obligations as it deems necessary at Tenant’s sole cost and expense. 
 26. DEFAULT. 
 A. Events of Default. The occurrence of any of the following shall constitute an event of default (“Event of Default” or “Default”) on the part of Tenant: 
 (1) Abandonment. Abandonment of the Premises for a continuous period in excess of five (5) days unless Tenant notifies
Landlord in writing in advance of such abandonment, keeps the Premises locked and secure at all times, and timely performs and continues to perform all of the Tenant’s other monetary and non-monetary obligations under this Lease. Tenant waives
any right to notice Tenant may have under Section 1951.3 of the Civil Code of the State of California, the terms of this Paragraph 26.A. being deemed such notice to Tenant as required by said Section 1951.3. 
 (2) Nonpayment of Rent. Failure to pay any installment of Rent or any other amount due and payable hereunder when said
payment is due. 
 (3) Other Obligations. Failure to perform any obligation, agreement or covenant under this
Lease other than those matters specified in subparagraphs (1) and (2) of this Paragraph 26.A., such failure continuing for fifteen (15) days after written notice of such 

  

 16 

 
failure. In the event Tenant has commenced to cure the failure of performance within the fifteen (15) day period, but has not completed the cure despite
diligent attempts to do so, Tenant shall have an additional period not to exceed thirty (30) additional days after such fifteen (15) day period to complete such cure so long as Tenant continues to diligently pursue the cure to completion
during such additional thirty (30) day period. 
 (4) General Assignment. A general assignment by Tenant
for the benefit of creditors. 
 (5) Bankruptcy. The filing of any voluntary petition in bankruptcy by Tenant,
or the filing of an involuntary petition by Tenant’s creditors, which involuntary petition remains undischarged for a period of sixty (60) days. In the event that under applicable law the trustee in bankruptcy or Tenant has the right to
affirm this Lease and continue to perform the obligations of Tenant hereunder, such trustee or Tenant shall, in such time period as may be permitted by the bankruptcy court having jurisdiction, cure all Defaults of Tenant hereunder outstanding as of
the date of the affirmance of this Lease and provide to Landlord such adequate assurances as may be necessary to ensure Landlord of the continued performance of Tenant’s obligations under this Lease. 
 (6) Receivership. The employment of a receiver to take possession of substantially all of Tenant’s assets or the
Premises, if such appointment remains undismissed or undischarged for a period of thirty (30) days after the order therefor. 
 (7) Attachment. The attachment, execution or other judicial seizure of all or substantially all of Tenant’s assets or the Premises, if such attachment or other seizure remains undismissed or undischarged for a period of
thirty (30) days after the levy thereof. 
 (8) Default under other Lease. If Tenant commits an Event of Default
under any other Lease or other tenancy arrangement between Landlord and Tenant, including, without limitation, an Event of Default under that certain Lease for 345 Oyster Point Boulevard, South San Francisco, California 90408 to which Landlord and
Tenant are parties. 
 B. Remedies Upon Default. 
 (1) Termination. In the event of the occurrence of any Event of Default, Landlord shall have the right to give a written
termination notice to Tenant, and on the date specified in such notice, Tenant’s right to possession shall terminate, and this Lease shall terminate unless on or before such date all arrears of rental and all other sums payable by Tenant under
this Lease and all costs and expenses incurred by or on behalf of Landlord hereunder shall have been paid by Tenant and all other Events of Default of this Lease by Tenant at the time existing shall have been fully remedied to the satisfaction of
Landlord. At any time after such termination, Landlord may recover possession of the Premises or any part thereof and expel and remove therefrom Tenant and any other person occupying the same, by any lawful means, and again repossess and enjoy the
Premises without prejudice to any of the remedies that Landlord may have under this Lease, or at law or equity by reason of Tenant’s Default or of such termination. 
 (2) Continuation After Default. Even though an Event of Default may have occurred, this Lease shall continue in effect for
so long as Landlord does not terminate Tenant’s right to possession under Paragraph 26.B.(1) hereof, and Landlord may enforce all of Landlord’s rights and remedies under this Lease, including without limitation, the right to recover Rent
as it becomes due, and Landlord, without terminating this Lease, may exercise all of the rights and remedies of a landlord under Section 1951.4 of the Civil Code of the State of California or any successor code section. Acts of maintenance,
preservation or efforts to lease the Premises or the appointment of a receiver upon application of Landlord to protect Landlord’s interest under this Lease shall not constitute an election to terminate Tenant’s right to possession.

 C. Damages After Default. Should Landlord terminate this Lease pursuant to the provisions of Paragraph
26.B.(1) hereof, Landlord shall have the rights and remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State of California, or successor code sections. Upon such termination, in addition to any other rights and remedies
to which Landlord may be entitled under applicable law, Landlord shall be entitled to recover from Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts which had been 

  

 17 

 
earned at the time of termination, (2) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after
termination until the time of award exceeds the amount of such Rent loss that Tenant proves could have been reasonably avoided; (3) the worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time
of award exceeds the amount of such Rent loss that the Tenant proves could be reasonably avoided; and (4) any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform
Tenant’s obligations under this Lease or which, in the ordinary course of things, would be likely to result therefrom. The “worth at the time of award” of the amounts referred to in (1) and (2), above shall be computed at the
lesser of the “prime rate,” as announced from time to time by Wells Fargo, N.A. (San Francisco) plus five (5) percentage points, or the maximum interest rate allowed by law (“Applicable Interest Rate”). The “worth at
the time of award” of the amount referred to in (3) above shall be computed by discounting such amount at the Federal Discount Rate of the Federal Reserve Bank of San Francisco at the time of the award plus one (1%) percent. If this
Lease provides for any periods during the Term during which Tenant is not required to pay Base Rent or if Tenant otherwise receives a Rent concession, then upon the occurrence of an Event of Default, Tenant shall owe to Landlord the full amount of
such Base Rent or value of such Rent concession, plus interest at the Applicable Interest Rate, calculated from the date that such Base Rent or Rent concession would have been payable. 
 D. Late Charge. If any installment of Rent is not paid on the date when due, such amount shall bear interest at the
Applicable Interest Rate from the date on which said payment shall be due until the date on which Landlord shall receive said payment. In addition, Tenant shall pay Landlord a late charge equal to five (5%) percent of the delinquency, to
compensate Landlord for the loss of the use of the amount not paid and the administrative costs caused by the delinquency, the parties agreeing that Landlord’s damage by virtue of such delinquencies would be difficult to compute and the amount
stated herein represents a reasonable estimate thereof. This provision shall not relieve Tenant of Tenant’s obligation to pay Rent at the time and in the manner herein specified. 
 E. Remedies Cumulative. All rights, privileges and elections or remedies of the parties are cumulative and not
alternative, to the extent permitted by law and except as otherwise provided herein. 
 27. LIENS. Tenant shall keep the
Premises free from liens arising out of or related to work performed, materials or supplies furnished or obligations incurred by Tenant or in connection with work made, suffered or done by or on behalf of Tenant in or on the Premises or Project. In
the event that Tenant shall not, within ten (10) business days following the imposition of any such lien, cause the same to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies
provided herein and by law, the right, but not the obligation, to cause the same to be released by such means as Landlord shall deem proper, including payment of the claim giving rise to such lien. All sums paid by Landlord on behalf of Tenant and
all expenses incurred by Landlord in connection therefor shall be payable to Landlord by Tenant on demand with interest at the Applicable Interest Rate. Landlord shall have the right at all times to post and keep posted on the Premises any notices
permitted or required by law, or which Landlord shall deem proper, for the protection of Landlord, the Premises, the Project and any other party having an interest therein, from mechanics’ and materialmen’s liens, and Tenant shall give
Landlord not less than ten (10) business days prior written notice of the commencement of any work in the Premises or Project which could lawfully give rise to a claim for mechanics’ or materialmen’s liens. 
 28. TRANSFERS BY LANDLORD. In the event of a sale or conveyance by Landlord of the Building or the Project or a foreclosure by any creditor
of Landlord, the same shall operate to release Landlord from any liability upon any of the covenants or conditions, express or implied, herein contained in favor of Tenant, to the extent required to be performed after the passing of title to
Landlord’s successor-in-interest. In such event, Tenant agrees to look solely to the responsibility of the successor-in-interest of Landlord under this Lease with respect to the performance of the covenants and duties of “Landlord” to
be performed after the passing of title to Landlord’s successor-in-interest. This Lease shall not be affected by any such sale and Tenant agrees to attorn to the purchaser or assignee. Landlord’s successor(s)-in-interest shall not have
liability to Tenant with respect to the failure to perform all of the obligations of “Landlord”, to the extent required to be performed prior to the date such successor(s)-in-interest became the owner of the Building. 
  

 18 

 29. RIGHT OF LANDLORD TO PERFORM TENANT’S COVENANTS. All covenants and agreements to
be performed by Tenant under any of the terms of this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any abatement of Rent. If Tenant shall fail to pay any sum of money, other than Base Rent and Basic Operating
Cost, required to be paid by Tenant hereunder or shall fail to perform any other act on Tenant’s part to be performed hereunder, and such failure shall continue for five (5) days after notice thereof by Landlord, Landlord may, but shall
not be obligated to do so, and without waiving or releasing Tenant from any obligations of Tenant, make any such payment or perform any such act on Tenant’s part to be made or performed. All sums, so paid by Landlord and all necessary
incidental costs together with interest thereon at the Applicable Interest Rate from the date of such payment by Landlord shall be payable to Landlord on demand, and Tenant covenants to pay such sums, and Landlord shall have, in addition to any
other right or remedy of Landlord, the same right and remedies in the event of the non-payment thereof by Tenant as in the case of Default by Tenant in the payment of Base Rent and Basic Operating Cost. 
 30. WAIVER. If either Landlord or Tenant waives the performance of any term, covenant or condition contained in this Lease, such waiver
shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition contained herein. The acceptance of Rent by Landlord shall not constitute a waiver of any preceding breach by Tenant of any term,
covenant or condition of this Lease, regardless of Landlord’s knowledge of such preceding breach at the time Landlord accepted such Rent. Failure by Landlord to enforce any of the terms, covenants or conditions of this Lease for any length of
time shall not be deemed to waive or to decrease the right of Landlord to insist thereafter upon strict performance by Tenant. Waiver by Landlord of any term, covenant or condition contained in this Lease may only be made by a written document
signed by Landlord. 
 31. NOTICES. Each provision of this Lease or of any applicable governmental laws, ordinances,
regulations and other requirements with reference to sending, mailing or delivery of any notice or the making of any payment by Landlord or Tenant to the other shall be deemed to be complied with when and if the following steps are taken:

 A. Rent. All Rent and other payments required to be made by Tenant to Landlord hereunder shall be
payable to Landlord at the address set forth in the Basic Lease Information, or at such other address as Landlord may specify from time to time by written notice delivered in accordance herewith. Tenant’s obligation to pay Rent and any other
amounts to Landlord under the terms of this Lease shall not be deemed satisfied until such Rent and other amounts have been actually received by Landlord. 
 B. Other. All notices, demands, consents and approvals which may or are required to be given by either party to the other hereunder shall be in writing and either personally delivered, sent by
commercial overnight courier, sent by facsimile, or mailed, certified or registered, postage prepaid, and addressed to the party to be notified at the address for such party as specified in the Basic Lease Information or to such other place as the
party to be notified may from time to time designate by at least fifteen (15) days notice to the notifying party. Notices shall be deemed served upon receipt or refusal to accept delivery. Tenant appoints as its agent to receive the service of
all default notices and notice of commencement of unlawful detainer proceedings the person in charge of or apparently in charge of occupying the Premises at the time, and, if there is no such person, then such service may be made by attaching the
same on the main entrance of the Premises. 
 32. ATTORNEYS’ FEES. In the event that Landlord places the enforcement of
this Lease, or any part thereof, or the collection of any Rent due, or to become due hereunder, or recovery of possession of the Premises in the hands of an attorney, Tenant shall pay to Landlord, upon demand, Landlord’s reasonable
attorneys’ fees and court costs. In any action which Landlord or Tenant brings to enforce its respective rights hereunder, the unsuccessful party shall pay all costs incurred by the prevailing party including reasonable attorneys’ fees, to
be fixed by the court, and said costs and attorneys’ fees shall be a part of the judgment in said action. 
 33. SUCCESSORS AND
ASSIGNS. This Lease shall be binding upon and inure to the benefit of Landlord, its successors and assigns, and shall be binding upon and inure to the benefit of Tenant, its successors, and to the extent assignment is approved by Landlord
hereunder, Tenant’s assigns. 
  

 19 

 34. FORCE MAJEURE. In the event that Landlord shall be delayed, hindered in or prevented
from the performance of any act or obligation required under this Lease by reason of acts of God, strikes, lockouts, labor troubles or disputes, inability to procure or shortage of materials or labor, failure of power or utilities, delay in
transportation, fire, vandalism, accident, flood, severe weather, other casualty, governmental requirements, riot, insurrection, civil commotion, sabotage, explosion, war, natural or local emergency, acts or omissions of others, including Tenant, or
other reasons of a similar or dissimilar nature not solely the fault of, or under the exclusive control of, Landlord (individually and collectively, “Force Majeure”), then performance of such act or obligation shall be excused for the
period of the delay and the period for the performance of any such act or obligations shall be extended for the period equivalent to the period of such delay. 
 35. BROKERAGE COMMISSION. Landlord shall pay a brokerage commission to Broker in accordance with a separate agreement between Landlord and Broker. Tenant warrants to Landlord that Tenant’s sole
contact with Landlord or with the Premises in connection with this transaction has been directly with Landlord and Broker, and that no other broker or finder can properly claim a right to a commission or a finder’s fee based upon contacts
between the claimant and Tenant with respect to Landlord or the Premises. Tenant shall indemnify, defend by counsel acceptable to Landlord, protect and hold Landlord harmless from and against any loss, cost or expense, including, but not limited to,
attorneys’ fees and costs, resulting from any claim for a fee or commission by any broker or finder in connection with the Premises and this Lease, other than Broker, who claims such right based upon contacts between claimant and Tenant.

claimant and Landlord.

 20 

 I. Accord and Satisfaction. No payment by Tenant of a lesser amount
than the Rent nor any endorsement on any check or letter accompanying any check or payment of Rent shall be deemed an accord and satisfaction, of full payment of Rent, and Landlord may accept such payment without prejudice to Landlord’s right
to recover the balance of such Rent or to pursue other remedies. 
 J. Easements. Landlord may grant
easements on the Project and dedicate for public use portions of the Project without Tenant’s consent; provided that no such grant or dedication shall substantially interfere with Tenant’s use of the Premises. Upon Landlord’s demand,
Tenant shall execute, acknowledge and deliver to Landlord documents, instruments, maps and plats necessary to effectuate Tenant’s covenants hereunder. 
 K. Drafting and Determination Presumption. The parties acknowledge that this Lease has been agreed to by both the parties, that both Landlord and Tenant have consulted with attorneys with respect

 M. No Light, Air or View Easement. Any diminution or shutting off of light, air or view by any
structure which may be erected on lands adjacent to or in the vicinity of the Building shall in no way affect this Lease or impose any liability on Landlord. 
 N. No Third Party Benefit. This Lease is a contract between Landlord and Tenant and nothing herein is intended to
create any third party benefit. 
 O. Waiver of Jury Trial. IF ANY ACTION OR PROCEEDING BETWEEN
LANDLORD AND TENANT TO ENFORCE THE PROVISIONS OF THIS LEASE (INCLUDING AN ACTION OR PROCEEDING BETWEEN LANDLORD AND THE TRUSTEE OR DEBTOR IN POSSESSION WHILE TENANT IS A DEBTOR IN A PROCEEDING UNDER ANY BANKRUPTCY LAW) PROCEEDS TO TRIAL, LANDLORD
AND TENANT HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY IN SUCH TRIAL. Landlord and Tenant agree that this Paragraph constitutes a written consent to waiver of trial by jury within the meaning of California Code of Civil Procedure
Section 631(a)(2), and Tenant does hereby authorize and empower Landlord to file this Paragraph and or this Lease, as required, with the clerk or judge of any court of competent jurisdiction as a written consent to waiver of jury trial.

 37. ADDITIONAL PROVISIONS. 
 A. ERISA Representations. Tenant represents to Landlord that, except for the Lease of the building commonly known as 345 Oyster Point Boulevard, South San Francisco, California 94080, neither
Tenant, nor any affiliate of the Tenant is a tenant under a lease or any other tenancy arrangement with Landlord or any affiliate of Landlord as of the date of this Lease. 
 B. Anti-Discrimination. There shall be no discrimination against or segregation of any person or group of persons, on
account of race, color, creed, religion, sex, marital status, national origin, or ancestry, in the leasing, subleasing, transferring, use, occupancy, tenure or enjoyment of the Premises, nor shall the Tenant or any person claiming under or through
the Tenant establish or permit any such practice or practices of discrimination or segregation with reference to the selection, location, number, use or occupancy of tenants, sublessees, subtenants, or vendees in the Premises. 
 C. Intentionally Omitted.  
 D. Option to Extend Term. Provided that Tenant is not in Default as of the time of exercise of each option and the
commencement date of each Option Period, Tenant shall have two (2) successive five (5) year options to extend the Term of the Lease for the Premises in “as is” condition at the expiration of the original Lease Term and, if the
first option is duly exercised, at the end of the first Option Term. All of the terms and conditions of this Lease except for Base Rent and the provisions of this Paragraph shall be applicable to the Option Period. 
  

 21 

 The Base Rent for the Premises under such option shall be the then current market rent for comparable facilities in the
proximate South San Francisco market area. The definition of comparable facilities shall incorporate the parking amenities of the Premises, and the Building’s location, age, quality, amenities, identity, exterior appearance, interior
improvements, and type of construction. 
 Tenant shall give Landlord written notice to exercise its option at least nine (9) but not more than twelve
(12) months prior to the expiration of the then current Term for the Premises. Within fifteen (15) days after Tenant exercises its option to extend, Landlord shall provide Tenant with the Base Rent, as determined by Landlord, for the
Option Period. The parties are obligated to negotiate in good faith to agree on the Base Rent. If the parties have not mutually agreed on the Base Rent within thirty (30) days from notification by Landlord to Tenant of Landlord’s
determination of Base Rent, each party hereto shall appoint one representative who shall be a licensed real estate broker experienced in the leasing of comparable facilities in the County of San Mateo to act as an arbitrator. The two
(2) arbitrators so appointed shall determine the Base Rent for the relevant Option Period. The determination of said Base Rent shall be made by said two (2) arbitrators within sixty (60) days from notification by Landlord to Tenant of
Landlord’s determination of Base Rent and they shall submit said determination in writing and signed by said arbitrators in duplicate. One of the written notifications shall be delivered to Landlord and the other to Tenant. 
 In the event the two (2) arbitrators of the parties hereto cannot agree on the Base Rent for the Premises herein, said two (2) arbitrators shall appoint a
third arbitrator who shall be a licensed real estate broker experienced in the leasing of comparable facilities in the County of San Mateo, to act as an arbitrator. The Base Rent for the relevant Option Period shall be independently determined by
the third of said arbitrators, which said determination shall be made within ninety (90) days from notification by Landlord to Tenant of Landlord’s determination of Base Rent. The role of the third arbitrator shall then be to immediately
select from the proposed resolution of arbitrators #1 and #2 the one that most closely approximates the third arbitrator’s determination of Base Rent. The third arbitrator shall have no right to adopt a compromise or middle ground or any
modification of either of the two final proposed resolutions. The resolution that the third arbitrator chooses as most closely approximating his determination of the Base Rent shall constitute the decision of all arbitrators and shall be final and
binding upon the parties. 
 The parties hereto shall pay the charges of the arbitrator appointed by it and any expenses incurred by such arbitrator. The
charges and expenses of the third arbitrator, as provided herein, shall be paid by the parties hereto in equal shares. 
 In the event either arbitrator #1
or arbitrator #2 fails to present a Base Rent figure within the thirty (30) day period, the Base Rent presented by the other arbitrator shall be considered final and binding on both parties. 
 Notwithstanding anything to the contrary herein contained, Tenant’s right to extend the term by exercise of the foregoing Option shall be conditioned upon the
following: (I) at the time of the exercise of the Option, and at the time of the commencement of the extended term, Tenant or a Permitted Assignee shall be in possession of and occupying the Premises for the conduct of its business therein and
the same shall not be occupied by any other assignee, subtenant or licensee, and (ii) the notice of exercise shall constitute a representation by Tenant to Landlord effective as of the date of the exercise and as of the date of commencement of
the extended term, that Tenant does not intend to seek to assign the lease in whole or in part, or sublet all of any portion of the Premises, the election to extend the term being for purposes of utilizing the Premises for Tenant’s purposes in
the conduct of Tenant’s or a Permitted Assignee’s business therein.
