ARMO BIOSCIENCES, INC., a Delaware corporation (“Sublandlord”) and BOLT BIOTHERAPEUTICS, INC., a Delaware corporation (“Subtenant”), all with respect to the following: 

RECITALS 
 WHEREAS, HCP
LS REDWOOD CITY, LLC, a Delaware limited partnership (“Master Landlord”) entered into that certain “LEASE (SEAPORT CENTRE)” with Sublandlord (the “Master Lease”) dated as of
March 16, 2018 and pursuant to which Master Landlord leased to Sublandlord certain space comprising 25,956 rentable square feet situated on the second (2nd) floor of the building
located at 900 Chesapeake Drive, Redwood City, California 94063 (the “Sublease Premises”), and pursuant to which Master Landlord granted Sublandlord certain rights to the Common Areas as more particularly described in the Master
Lease, all upon the terms and conditions contained therein. (All capitalized terms used herein shall have the same meaning ascribed to them in the Master Lease unless otherwise defined herein. A redacted copy of the Master Lease is attached hereto
as Exhibit A and made a part hereof); and 
 WHEREAS, (i) Sublandlord now wishes to sublease all of the Sublease Premises
to Subtenant, and Subtenant wishes to sublease all of the Sublease Premises from Sublandlord, all on the terms and conditions hereafter set forth, and (ii) Sublandlord and Subtenant are now entering into this Sublease in furtherance thereof.

 AGREEMENT 
 NOW,
THEREFORE, in consideration of the mutual covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto mutually covenant and agree as follows: 

1.    Demise and Condition of Space; Accessibility; Personal Property. Sublandlord hereby subleases to
Subtenant, and Subtenant hereby subleases from Sublandlord, the Sublease Premises upon the terms and conditions set forth herein and in the Master Lease, as incorporated herein. Subtenant understands, acknowledges and agrees that: (i) the
rentable square footage of the Sublease Premises shall not be subject to re-measurement or adjustment during the Term, (ii) Subtenant has had the opportunity to inspect the Sublease Premises, and
Subtenant is subleasing the Sublease Premises from Sublandlord in its “AS IS, WHERE IS, WITH ALL FAULTS” condition, (iii) Sublandlord has not made and is not making any representations or warranties whatsoever concerning the
condition of the Building or the Sublease Premises, and (iv) Sublandlord is not obligated to perform any work to prepare the Sublease Premises for Subtenant’s occupancy, in each case except as otherwise expressly set forth in this
Sublease. Sublandlord shall further not be responsible for the cost, nor the installation, of any phone systems, data cabling or security systems. Sublandlord shall deliver possession of the Sublease Premises to Subtenant on receipt of Master
Landlord’s written consent hereto in good, vacant, broom clean condition, and otherwise in the condition as of the date hereof. 

Pursuant to Section 1938 of the California Civil Code, Sublandlord hereby advises Subtenant that the Sublease Premises has not undergone
inspection by a Certified Access Specialist (a “CASp”) during the Sublandlord’s tenure as Tenant under the Master Lease, nor, to Sublandlord’s actual knowledge (without any duty of inquiry, as of the Sublease Effective
Date), prior to Sublandlord’s tenure as Tenant under the Master Lease. Further, pursuant to Section 1938 of the California Civil Code, Sublandlord notifies Subtenant of the following: “A Certified Access Specialist (CASp) can inspect
the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the
commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if


  
 1 














 
requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection and the cost
of making any repairs necessary to correct violations of construction-related accessibility standards within the premises.” Therefore and notwithstanding anything to the contrary contained in this Sublease, Sublandlord and Subtenant agree that
(i) Subtenant may, at its option and at its sole cost, cause a CASp to inspect the Sublease Premises and determine whether the Sublease Premises complies with all of the applicable construction-related accessibility standards under state law,
(ii) the parties shall mutually coordinate and reasonably approve of the timing of any such CASp inspection so that Sublandlord may, at its option, have a representative present during such inspection, and (iii) Subtenant shall be solely
responsible for the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the Sublease Premises identified in such report that are then required by law to be corrected. 

In addition to Sublandlord’s demise of the Sublease Premises to Subtenant, Sublandlord further hereby sells, assigns, transfers and
conveys to Subtenant on the Sublease Commencement Date all of Sublandlord’s right, title and interest in and to the furniture, equipment and cabling located within the Sublease Premises as of the date of this Sublease (which furniture,
equipment and cabling are listed on Exhibit B attached hereto), for the total amount of One Dollar ($1.00). In connection therewith, Subtenant expressly understands, acknowledges and agrees that it shall accept all such furniture, equipment
and cabling in its “AS IS WITH ALL FAULTS” condition, and Sublandlord makes no, and expressly disclaims any, representation or warranty as to the condition, merchantability, reliability, fitness for any particular purpose or
otherwise in respect of the furniture, equipment and cabling. Subtenant shall be solely responsible for any sales or transfer tax associated with Sublandlord’s conveyance of such furniture, equipment and cabling to Subtenant. 

2.    Lease Term. The term of this Sublease (“Term”) shall commence sixty (60) days
following Sublandlord’s delivery of the Sublease Premises to Subtenant in the required condition and receipt of Master Landlord’s written consent to this Sublease (the “Sublease Commencement Date”) and shall expire on
July 31, 2025 (the “Sublease Expiration Date”), unless sooner terminated as provided herein. Subtenant expressly agrees that it shall have no right to extend the Term of this Sublease or to require that
Sublandlord exercise its option rights under Section 2.2 “Option Term” of the Master Lease, and Sublandlord agrees that it will not exercise its option rights under Section 2.2 “Option Term” of the Master
Lease or otherwise extend the term of the Master Lease. Sublandlord and Subtenant each further understand, acknowledge and agree that the Sublease Expiration Date occurs at the end of the Lease Term under the Master Lease, and that both parties
intend for this Sublease to be characterized as a sublease of the Sublease Premises, and not as an assignment of Sublandlord’s rights under the Master Lease. On the last day of the Term, or on the sooner termination of this Sublease, Subtenant
shall surrender the Sublease Premises to Sublandlord in as good condition and repair as received, normal wear and tear excepted, with all alterations or improvements made by Subtenant removed, to the extent properly required by Master Landlord,
without damage to the Sublease Premises or the Building, and otherwise in the manner required by the Master Lease, as incorporated herein, including, without limitation, the provisions of Section 15 “Surrender Of Premises; Ownership And
Removal Of Trade Fixtures” of the Master Lease. Subtenant shall have the right to enter the Sublease Premises during the sixty (60) day period following Sublandlord’s delivery of the Sublease Premises to Subtenant in the required
condition and receipt of Master Landlord’s written consent (the “Early Access Period”), for the limited purposes of preparing the Sublease Premises for occupancy and occupancy of completed areas. Such entry and occupancy shall
be on all of the terms of this Sublease, except that Subtenant shall not be required to pay any rent during the Early Access Period; provided, however, that Subtenant shall be responsible for the payment of all utilities and other services which
Subtenant uses in the Sublease Premises during the Early Access Period. 
 3.    Use; Hazardous Materials.
The Sublease Premises shall be used and occupied by Subtenant only for general office, research and development, engineering, laboratory, storage and/or warehouse uses, including, but not limited to, administrative offices and other lawful uses
reasonably related to or incidental to such specified uses, all being: (i) consistent with First Class Life Sciences Projects, and (ii) in compliance with, and subject to, applicable laws and all of the terms of the Master Lease,
including without limitation, in compliance with the prohibited uses described in Section 5.2 “Prohibited Uses” of the Master Lease and in compliance with any rules and regulations established by Master Landlord under the


  
 2 














 
Master Lease pursuant to Master Landlord’s rights under Section 5.2 “Prohibited Uses” of the Master Lease. Subtenant shall be solely responsible for obtaining any
permits or licenses necessary to conduct and operate its business within the Sublease Premises, and Sublandlord makes no representations or warranties about the suitability of the Sublease Premises for the conduct of Subtenant’s business.
Subtenant assumes all risk of damage to property and/or injury to persons in, on or about the Sublease Premises from any cause whatsoever. Sublandlord shall not be responsible in any way for any personal injuries, property damage, lost profits, loss
of business or any other expenses incurred by Subtenant from any cause. 
 Subtenant shall further be responsible for complying with all of
the requirements and obligations set forth in Section 5.3 “Hazardous Materials” of the Master Lease, as incorporated herein, including, without limitation: (i) completion of a new Environmental Questionnaire if required by
Master Landlord, (ii) cooperating with the Master Landlord regarding any Environmental Assessment desired by Master Landlord pursuant to the provisions of Section 5.3.2.1 “Environmental Assessments in General” of the
Master Lease, and paying the cost therefore as and to the extent required under Section 5.3.2.2 “Cost of Environmental Assessments” of the Master Lease, (iii) providing a separate Environmental Assessment and surrendering
the Sublease Premises in the manner required by Section 5.3.3 “Tenant’s Obligations upon Surrender” and Section 15.3 “Environmental Assessment” of the Master Lease, and (iv) completing any Clean
Up of the Sublease Premises as and to the extent required by Section 5.3.4 “Clean Up” of the Master Lease. Any notices sent to Master Landlord pursuant to Section 5.3 “Hazardous Materials” of the Master
Lease shall concurrently be sent to Sublandlord. In connection with Subtenant’s use and maintenance of Hazardous Materials within the Sublease Premises, Subtenant shall and hereby does protect, defend, indemnify and hold Sublandlord and its
directors, officers, employees and agents (collectively, the “Sublandlord Indemnitees”) harmless from and against any and all claims, judgments, losses, damages, costs, expenses, penalties, enforcement actions, taxes, fines,
remedial actions, liabilities (including, without limitation, actual attorney’s fees, litigation, arbitration and administrative proceeding costs, expert and consultant fees and laboratory costs) including, without limitation, consequential
damages and sums paid in settlement of claims, which arise during or after the Term, whether foreseeable or unforeseeable, in whole or in part and directly or indirectly as a result of or attributable to the presence, use, generation, manufacture,
treatment, handling, refining, production, processing, storage, Release or presence of Hazardous Materials in, on, under or about the Sublease Premises by Subtenant or any of its employees, contractors, subcontractors or any other person or entity
acting as an agent or sub-agent of Subtenant. 
 4.    Rent and Rent

 (a)    Base Rent. Beginning on the Sublease Commencement Date (the “Rent

 3 














 The first monthly installment of Base Rent shall be paid by Subtenant upon the execution of this Sublease
and shall be applied to the Base Rent for the first calendar month, or portion thereof, following the Rent Commencement Date for which Base Rent is due and payable; provided, however, that if the Term begins or ends on a day other than the first or
last day of the month, the Base Rent for the partial months shall be prorated on a per diem basis. The foregoing notwithstanding, Sublandlord hereby agrees that Base Rent, but not Additional Rent, for Subtenant shall be conditionally abated
during the first four (4) months of the Term (such period being referred to herein as the “Base Rent Abatement Period”, and such abated Base Rent during the Base Rent Abatement Period being referred to herein as the
“Abated Rent”). Base Rent and all additional rent (including without limitation, Additional Rent payable under the Master Lease, default interest, late fees and other amounts owing hereunder) shall hereinafter be collectively
referred to as “Rent.” 
 (b)    Additional Rent. Beginning on the Sublease Commencement
Date and continuing to the Sublease Expiration Date, but subject to Subtenant’s rights to the Abated Rent, Subtenant shall pay to Sublandlord as additional rent for this subletting all of Tenant’s Share of the Direct Expenses that are
payable by Sublandlord to Master Landlord under the Master Lease, together with any and all other Additional Rent payable under the Master Lease, as incorporated herein, and together with any and all other additional expenses, costs and charges
payable to Master Landlord under the Master Lease, as incorporated herein, in connection with Subtenant’s use of the Sublease Premises. Sublandlord and Subtenant each understand, acknowledge and agree that Subtenant shall be obligated to pay
Tenant’s Share of the Direct Expenses for the Sublease Premises during the Base Rent Abatement Period where Base Rent is not being charged. Tenant’s Share of Direct Expenses is currently calculated at
Twenty-Two Thousand Nine Hundred Forty-Seven and 26/100 Dollars ($22,947.26) per month; provided, however, that Subtenant further understands, acknowledges and agrees that Tenant’s Share of Direct
Expenses is subject to adjustment, and is further subject to such other charges as are more particularly set forth in the Master Lease, as incorporated herein. Sublandlord agrees to promptly notify Subtenant of any increase in or other statements
for the payment of Tenant’s Share of Direct Expenses or Additional Rent under the Master Lease, and of any other amounts owing to Master Landlord under the Master Lease, and Subtenant agrees to pay Sublandlord for all such additional amounts
within thirty (30) days of receipt of Sublandlord’s written notice thereof. Subtenant shall be entitled to all credits, if any, given by Master Landlord to Sublandlord for Sublandlord’s overpayment of such amounts during the Term.

 (c)    Payment of Rent. Except as otherwise specifically provided in this Sublease, Rent shall be
payable in lawful money without demand, and without offset, counterclaim, or setoff in monthly installments, in advance, on the first day of each and every month during the Term of this Sublease. All of said Rent is to be paid to Sublandlord or at
such other place or to such agent and at such place as Sublandlord may designate by written notice to Subtenant. Any Additional Rent payable by Sublandlord to Master Landlord under the Master Lease shall be paid to Sublandlord as and when such items
are payable by Sublandlord to Master Landlord under the Master Lease, unless a different time for payment is elsewhere stated herein. Sublandlord agrees to provide Subtenant promptly with copies of any statements or invoices or notices received by
Sublandlord from Master Landlord or given by Sublandlord to Master Landlord pursuant to the terms of the Master Lease. 

(d)    Default Interest; Late Charge. Subject to the terms of the second sentence of Section 25 of the
Master Lease, as incorporated herein, if Subtenant fails to pay any Rent within ten (10) days after due, Sublandlord and Subtenant each agree that (i) Sublandlord will or may incur additional expenses in the form of extra collection
efforts, handling costs, and potential impairment of credit on liens for which this Sublease is security; (ii) it is extremely difficult and impractical to ascertain the extent of detriment; (iii) the amount described herein is and will be
reasonable; and, (iv) Sublandlord shall be entitled to recover from Subtenant as liquidated damages the greater of Five Hundred Dollars ($500) or three percent (3%) of the amount due (“Late Fee”). Past due amounts shall also
bear interest at the rate of twelve percent (12%) per annum or the maximum rate permitted by law, whichever is less (“Interest Rate”). Notwithstanding the foregoing, the obligation to pay the Late Fee and/or interest at the Interest
Rate shall not alter or preclude Sublandlord’s right, prior to actual receipt of any delinquent installment of Rent, to exercise any right or remedy which Sublandlord may have under the terms of this Sublease or under applicable law.
Furthermore, acceptance of any monies by Sublandlord shall not constitute a waiver by 

  
 4 














 
Sublandlord of Subtenant’s breach or prevent Sublandlord from exercising any other right or remedies available to Sublandlord as provided herein or by law, except for offsets to damages to
the extent of amounts received by Sublandlord for Subtenant’s benefit. 
 5.    Subtenant’s Security
Deposit. Upon execution of this Sublease, Subtenant shall deliver to Sublandlord a letter of credit in a form and issued by a lending institution reasonably satisfactory to Sublandlord (the “Letter of Credit”), payable to
Sublandlord in the amount of Five Hundred Eighty-Four Thousand Ten Dollars ($584,010) and standing as a security deposit for Subtenant’s obligations under this Sublease. Sublandlord hereby approves of Silicon Valley Bank as the issuing lending
institution. The Letter of Credit shall be available to be drawn upon by Sublandlord in the event of a default by Subtenant under this Sublease beyond any applicable notice and cure periods, subject only to Sublandlord’s delivery to such
lending institution of an affidavit of default executed by an authorized agent of Sublandlord and given to the issuer of the Letter of Credit and to Subtenant, the delivery of which affidavit shall be a condition precedent to the drawing on the
Letter of Credit. The Letter of Credit shall be held by Sublandlord as security for the faithful performance by Subtenant of all of the terms and conditions of this Sublease. The Letter of Credit shall not be mortgaged, assigned, transferred, or
encumbered by Subtenant, and any act by Subtenant purporting to accomplish same shall be without force and effect and shall not be binding upon Sublandlord. Subtenant hereby waives the provisions of Section 1950.7 of the California Civil Code,
or any similar or successor laws now or hereafter in effect that limit the purposes for which security deposits can be used. Unless Sublandlord draws upon the Letter of Credit due to Subtenant’s failure to renew or provide a replacement Letter
of Credit within thirty (30) days prior to the expiration of the existing Letter of Credit, Sublandlord shall only draw upon the Letter of Credit following a default beyond applicable notice and cure periods and only to the extent required to
cure the default. In the event that Sublandlord draws upon the Letter of Credit (i) solely due to Subtenant’s failure to renew the Letter of Credit at least thirty (30) days before its expiration, such failure to renew shall not
constitute a default hereunder, and Sublandlord shall be entitled to hold the cash proceeds from its draw upon the Letter of Credit in lieu of the Letter of Credit and use the same in the same manner and for the same purposes as were permitted with
respect to the Letter of Credit, and (ii) Subtenant shall at any time thereafter be entitled to provide Sublandlord with a replacement Letter of Credit that satisfies all of the requirements above, at which time Sublandlord shall return the
cash proceeds of the original Letter of Credit drawn by Sublandlord. 
 6.    Signage; Parking. At
Subtenant’s sole cost and expense, Subtenant shall be entitled to exercise all of Sublandlord’s rights to signage at the Building and with respect to the Sublease Premises as are set forth in Section 23 “Signs” of the
Master Lease; provided, however, that Subtenant shall be required to obtain all requisite consents and approvals from Master Landlord as are set forth in such Section, and shall be subject to all of the obligations of Sublandlord in such Section.
Subtenant shall further be entitled to use all of the parking rights afforded to Sublandlord under the provisions of Section 28 “Tenant Parking” of the Master Lease, and Subtenant shall further be subject to all requirements
and all obligations set forth in the Master Lease with respect to the use and enjoyment of such parking rights, including compliance with all rules and regulations established by Master Landlord with respect to such parking rights. The parking
spaces shall be governed by all of the terms of the Master Lease. 
 7.    Alterations; Restoration.
Subtenant acknowledges and agrees that it is not authorized to make any alterations or improvements in or to the Sublease Premises, except (i) as permitted without consent in the second sentence of Section 8.1 of the Master Lease provided
that Subtenant shall be responsible, at its sole cost and expense, for the removal of any such alterations or improvements as and to the extent required by Master Landlord under the Master Lease, and (ii) as expressly permitted and approved in
writing by Sublandlord and Master Landlord and by the provisions of this Sublease and the Master Lease. Notwithstanding the foregoing, (a) subject to its review of more detailed plans and receipt of Master Landlord’s written consent,
Sublandlord approves Subtenant’s construction of the improvements described in Exhibit C (“Tenant Improvements”) and agrees for itself that Subtenant shall not be required to restore the Tenant Improvements or obtain any
bonds with respect thereto, subject to Master Landlord’s rights under the Master Lease to require removal of such Tenant Improvements and/or the securing of any bonds with respect thereto, and (b) Sublandlord shall not withhold its consent
to any alterations provided that Master Landlord approves them in writing, nor shall Sublandlord require that any improvements be restored unless Master Landlord requires such restoration pursuant to its rights under the Master Lease.


  
 5 














 
Subtenant further acknowledges and agrees and that it must deliver the Sublease Premises to Sublandlord on the Sublease Expiration Date in the condition required by the Master Lease, which
requires, but is not limited to, removing all moveable trade fixtures, furniture, equipment and other moveable personal property and repairing any damage caused thereby; provided, however, Sublandlord shall not be required to remove any alterations
in the Sublease Premises on the date hereof. The provisions of this Section 7 shall survive the expiration or earlier termination of this Sublease. 

8.    Insurance Coverage and Requirements. Subtenant covenants and agrees that it shall, as of the Sublease
Commencement Date and at its sole cost and expense, secure all of the insurance coverages required of Sublandlord in Section 10.3 “ Tenant’s Insurance” and Section 10.6 “Additional Insurance Obligations” of
the Master Lease, as incorporated herein, all in the forms required by Section 10.4 “Form of Policies”, as incorporated herein, naming Sublandlord and Master Landlord as additional insureds (on the liability policies), and
shall provide Sublandlord and Master Landlord certificates evidencing such coverages as are required by the terms of Section 10 “Insurance” of the Master Lease, as incorporated herein. In the event Subtenant shall fail to
procure such insurance, or to deliver such policies or certificates, Sublandlord may after ten (10) days’ written notice, at its option, procure such policies for the account of Subtenant, and the cost thereof shall be paid by Subtenant to
Sublandlord as Additional Rent within five (5) days after delivery to Subtenant of the bills therefore. Subtenant further expressly agrees that it shall and hereby does provide all of the waivers and indemnifications to both Master Landlord and
Sublandlord as are set forth in Section 10.1 “Indemnification and Waiver” of the Master Lease, as incorporated herein, all as if the same were fully set forth herein, and agrees that Subtenant shall comply with all of the
obligations set forth in Section 10.2 “Tenant’s Compliance With Landlord’s Property Insurance” of the Master Lease, as incorporated herein. Subtenant agrees to comply with all of the obligations and waivers set forth
in Section 10.5 “Subrogation” of the Master Lease, as incorporated herein, all as the same shall apply to both Master Landlord and Sublandlord. 

9.    Damage and Destruction; Condemnation. Subtenant agrees that it shall comply with all of the
requirements of Sublandlord under Section 11 “Damage and Destruction” of the Master Lease, as incorporated herein, including, without limitation, the obligation to assign any and all property insurance proceeds payable to
Subtenant under Subtenant’s insurance as to the Alterations to Master Landlord. Subtenant further acknowledges all of the Master Landlord’s rights under Section 11.2 “Landlord’s Option to Repair” in connection
with any such damage or destruction, and further consents to and hereby expressly provides to Sublandlord and Master Landlord the waivers set forth in Section 11.3 “Waiver of Statutory Provisions” of the Master Lease, as
incorporated herein. In the event of any damage or destruction of the Sublease Premises, Subtenant hereby agrees that any and all notices required thereunder of the “Tenant” shall be delivered by Subtenant concurrently to both
Sublandlord and Master Landlord. 
 In the event of a taking of all or a part of the Building, or in the event the Sublease Premises are
taken under power of eminent domain so as to render the Sublease Premises unusable or unavailable for the purposes set forth in this Sublease or in the Master Lease, Subtenant shall be entitled, subject to other provisions of this Sublease, to
exercise any right it may have to terminate the Master Lease, as incorporated herein. Subtenant hereby waives any and all rights under and benefits of Section 1265.130 of the California Civil Code. If neither Subtenant elects to terminate this
Sublease nor Master Landlord elects to terminate the Master Lease, then this Sublease shall continue in full force and effect, except that if Sublandlord’s rent is abated or otherwise adjusted under the Master Lease, then Subtenant’s Rent
payable under this Sublease shall also be abated or correspondingly adjusted on a pro-rata basis. 

10.    Assignment and Subletting. Except as permitted in Section 14.8 of the Master Lease, as
incorporated herein, Subtenant hereby expressly agrees that Subtenant shall not have the right to assign or sublet any of its right to the Sublease Premises without the express prior written consent of Sublandlord, which consent may be given or
withheld in Sublandlord’s reasonable discretion; provided, however, that any such sublease or assignment requested by Subtenant shall further be subject to Master Landlord’s rights and prior written consent and other conditions, all as and
to the extent set forth in Section 14 “Assignment and Subletting” of the Master Lease, including, without limitation, Master Landlord’s rights to the payment of any Transfer Premium under Section 14.3
“Transfer Premium” and Master Landlord’s right to recapture the Sublease Premises as set forth in Section 14.4 “Landlord’s Option as to Subject Space” of


  
 6 














 
the Master Lease, each as incorporated herein. In addition, subject to Master Landlord’s written consent, a transfer of Tenant’s stock or assignment in connection with a merger or sale
of substantially all of Subtenant’s assets shall not constitute a Transfer under this Sublease. 

11.    Incorporation of Terms of Master Lease. This Sublease and all rights of the parties hereunder are
subject and subordinate to the Master Lease. Subtenant agrees that it will not, by its act or omission to act where required to do so, cause a default under the Master Lease. In furtherance of the foregoing, the parties hereby acknowledge, each to
the other, that it is not practical in this Sublease to enumerate all of the rights and obligations of the various parties under the Master Lease and specifically to allocate those rights and obligations in this Sublease. Accordingly, in order to
afford to Subtenant the benefits of this Sublease and of those provisions of the Master Lease which by their nature are intended to benefit the party in possession of the Premises, and in order to protect Sublandlord against a default by Subtenant
which might cause a default by Sublandlord under the Master Lease, Sublandlord and Subtenant covenant and agree as set forth in this Section 11. 

(a)    Subject to the modifications set forth in this Sublease as between Sublandlord and Subtenant, the terms of
the Master Lease are incorporated herein by reference, and shall, as between Sublandlord and Subtenant (as if they were Landlord and Tenant, respectively, under the Master Lease), constitute the terms of this Sublease, except to the extent that they
are inapplicable to, inconsistent with, or expressly modified by the terms of this Sublease, and shall be binding upon and inure to the benefit of Sublandlord and Subtenant respectively. Notwithstanding the foregoing, Sublandlord and Subtenant agree
that: (i) each reference in such incorporated sections to “Lease” shall be deemed a reference to “Sublease”; (ii) each reference to “Lease Commencement Date”, “Lease Term” and
“Base Rent” shall be deemed a reference to the “Sublease Commencement Date”, “Term” and “Base Rent” under this Sublease, respectively; (iii) the following provisions shall not
be included: the introductory paragraph, Sections 1, 3-5, 8 and 10 and 12 of the Summary of Basic Lease Information, Sections 2.1 (first two sentences), 2.2, 3 (first two sentences), 21.1 (first sentence), 25
(except the second sentence), 29.18, 29.20 and 29.24 and Exhibit B of the Master Lease; (iv) references in the following provisions to “Landlord” shall mean “Master Landlord”: Sections
1.1.2, 1.1.3, 4.2.4, 4.2.5, 4.3, 5.2, 8.2-8.5, 10.6, 11.2, 13, 14.3, 14.4, 22 (the last sentence), 23, 28, 29.5, 29.13 (the first four sentences), 29.26, 29.29 and 29.31; (v) references in Sections 6.4 and
10.1 to “Landlord” shall mean “Master Landlord” and “Sublandlord”; (vi) wherever there is a requirement to pay the costs and expenses of “Landlord,” Subtenant shall only be
obligated to pay Master Landlord’s costs and expenses and not both Sublandlord’s and Master Landlord’s costs and expenses; (vii) all references to the Tenant Work Letter shall be deleted; (viii) at Subtenant’s request
and at Subtenant’s sole cost and expense, Sublandlord shall exercise its rights under Section 4.6 of the Master Lease and share the results thereof with Subtenant; and (ix) subject to Master Landlord’s written consent, Subtenant
may use the Hazardous Materials described in the Environmental Questionnaire attached hereto as Exhibit D. As between the parties hereto only, in the event of any inconsistencies between the terms and provisions of the
Master Lease, as incorporated herein, and the express terms and provisions of this Sublease, the express terms and provisions of this Sublease shall govern. Subtenant acknowledges that it has reviewed the Master Lease and is familiar with all of the
terms and conditions thereof. Subtenant further covenants and warrants that it fully understands and agrees to be subject to and bound by all of the covenants, agreements, terms, provisions and conditions of the Master Lease, as incorporated herein.

 (b)    Subtenant recognizes that Sublandlord is not in a position to render any of the services or to perform
any of the repair, restoration, maintenance, insurance or any other similar obligations required of the Master Landlord by the terms of the Master Lease, and that Sublandlord shall have no duty to perform any obligations of Master Landlord which
are, by their nature, the obligations of an owner or manager of real property. By way of illustration and not limitation, Sublandlord shall not be required to provide any services (including janitorial, utilities, HVAC service, security, or use of
Common Areas or parking facilities) or to perform any maintenance or repairs which Master Landlord is or may be required to provide or perform under the Master Lease. Sublandlord shall have no responsibility for or be liable to Subtenant for any
default, failure or delay on the part of Master Landlord in the performance or observance by Master Landlord of any of its obligations under the Master Lease, nor shall such default by Master Landlord affect this Sublease or waive or defer the
performance of any of Subtenant’s obligations under this Sublease, including without limitation the obligation to pay Rent; and Subtenant hereby expressly 

  
 7 














 
waives the provisions of any statute, ordinance or judicial decision, now or hereafter in effect, which would give Subtenant the right to make repairs at the expense of Sublandlord.
Notwithstanding the foregoing, the parties do contemplate that Master Landlord will, in fact, perform its obligations under the Master Lease and in the event of any default or failure of such performance by Master Landlord, Sublandlord agrees that
it will, upon notice from Subtenant, make demands upon Master Landlord to perform its obligations under the Master Lease. Any non-liability, release, indemnity or hold harmless provision in the Master Lease,
as incorporated herein, for the benefit of Master Landlord shall be deemed to apply under this Sublease and inure to the benefit of both Sublandlord and Master Landlord. Notwithstanding anything to the contrary contained in this Sublease, Subtenant
agrees that performance by Sublandlord of certain of its obligations hereunder are conditional upon due performance by the Master Landlord of its corresponding obligations under the Master Lease, and Sublandlord shall not be liable to Subtenant for
any default of the Master Landlord under the Master Lease. Subtenant shall not have any claim against Sublandlord by reason of the Master Landlord’s failure or refusal to comply with any of the provisions of the Master Lease unless such failure
or refusal is a result of Sublandlord’s act or failure to act pursuant to its obligations under this Sublease. Furthermore, Subtenant and Sublandlord further covenant not to take any action or do or perform any act or fail to perform any act
where it has an obligation to act which would result in the failure or breach of any of the covenants, agreements, terms, provisions or conditions of the Master Lease on the part of the Tenant thereunder. 

(c)    For the purposes of incorporation herein, the terms of the Master Lease are subject to the following
additional modifications: 
 (i)    In all provisions of the Master Lease (under the terms thereof and without
regard to modifications thereof for purposes of incorporation into this Sublease) requiring the approval or consent of the Master Landlord, Subtenant shall be similarly and correspondingly required to obtain the written approval or consent of both
Sublandlord and the Master Landlord. In furtherance thereof, if Subtenant desires to take any action which requires the consent of Master Landlord under the terms of the Master Lease, then, notwithstanding anything to the contrary herein:
(a) Sublandlord, independently, shall have the same rights of approval or disapproval as Master Landlord has under the Master Lease; (b) Subtenant shall not take any such action until it obtains the consent of both Sublandlord and Master
Landlord; and (c) Subtenant shall request that Sublandlord obtain Master Landlord’s consent on Subtenant’s behalf and Sublandlord shall use commercially reasonable efforts to obtain such consent. Subtenant shall pay all third party, out-of-pocket costs reasonably incurred by Sublandlord in seeking or procuring Master Landlord’s consent, and all costs reasonably incurred by Master Landlord in
providing Master Landlord’s consent to the extent required under the Master Lease. Any approval or consent required of Sublandlord conclusively shall be deemed reasonably withheld if approval or consent also is required of the Master Landlord,
and Master Landlord fails to give Master Landlord’s approval or consent. All costs of seeking or obtaining Master Landlord’s consent, whether or not obtained, shall be borne by Subtenant. 

(ii)    In all provisions of the Master Lease, as incorporated herein, requiring Tenant to submit, exhibit to,
supply or provide Master Landlord with evidence, certificates, or any other matter or thing, Subtenant shall be similarly and correspondingly required to submit, exhibit to, supply or provide, as the case may be, the same to both the Master Landlord
and Sublandlord. In any such instance, Sublandlord shall determine if such evidence, certificate or other matter or thing shall be satisfactory. 

(iii)    Sublandlord shall have no obligation to perform any obligations of the Master Landlord to, nor shall
Sublandlord have any independent obligation to, restore or rebuild any portion of the Sublease Premises after any destruction or taking by eminent domain. 

12.    Subtenant’s Obligations under the Master Lease; Subtenant’s Indemnities. Subtenant
covenants and agrees that all obligations of Sublandlord as Tenant under the Master Lease, as incorporated herein, shall be done or performed by Subtenant with respect to the Sublease Premises, except as otherwise expressly provided by this
Sublease, and Subtenant’s obligations shall run to Sublandlord and Master Landlord as Sublandlord may determine to be appropriate or be required by the respective interests of Sublandlord and Master Landlord. In furtherance of the foregoing,
Subtenant shall and hereby does protect, defend, indemnify and hold Sublandlord and the Sublandlord Indemnitees 

  
 8 














 
harmless from and against any and all claims, judgments, losses, damages, costs, expenses, penalties, enforcement actions, taxes, fines, remedial actions, liabilities (including, without
limitation, actual attorney’s fees, litigation, arbitration and administrative proceeding costs, expert and consultant fees and laboratory costs) including, without limitation, consequential damages and sums paid in settlement of claims, which
arise during or after the Term, whether foreseeable or unforeseeable, in whole or in part and directly or indirectly as a result of or attributable to the non-performance,
non-observance or non-payment of any of Sublandlord’s covenants, warranties, or payment or other obligations under the Master Lease that, as a result of this
Sublease, became an obligation of Subtenant. Subtenant shall not do, nor permit to be done, any act or thing that is, or with notice or the passage of time would be, a default under this Sublease or the Master Lease. The provisions of this
Section 12 shall survive the expiration or earlier termination of this Sublease. Sublandlord hereby assigns to Subtenant all warranties given and indemnities made by Master Landlord to Sublandlord under the Master Lease
which would reduce Subtenant’s obligations hereunder, and shall cooperate with Subtenant to enforce all such warranties and indemnities, if any. 

Except to the extent due to the gross negligence, willful misconduct or violation of this Sublease or the Master Lease by Sublandlord or
Master Landlord, Subtenant, as a material part of the consideration to be rendered to Sublandlord under this Sublease, shall and hereby does protect, defend, indemnify and hold Sublandlord and the Sublandlord Indemnitees harmless from and against
any and all claims, judgments, losses, damages, costs, expenses, penalties, enforcement actions, taxes, fines, remedial actions, liabilities (including, without limitation, actual attorney’s fees, litigation, arbitration and administrative
proceeding costs, expert and consultant fees and laboratory costs) including, without limitation, consequential damages and sums paid in settlement of claims, which arise during or after the Term, whether foreseeable or unforeseeable, in whole or in
part and directly or indirectly as a result of or attributable to Subtenant’s use, occupancy or enjoyment of the Sublease Premises and its facilities or the conduct of Subtenant’s business or from any activity, work or things done,
permitted or suffered by Subtenant, or its agents, employees and invitees in or about the Sublease Premises. Subtenant agrees to pay for all damages to the Building, as well as all damage to the tenants or occupants thereof, to the extent caused by
Subtenant’s negligence, misuse, or neglect of said Sublease Premises or appurtenances, as provided in Section 10.1 of the Master Lease, as incorporated herein. Notwithstanding anything to the contrary herein, Sublandlord shall not be
released or indemnified from, and shall indemnify, defend, protect and hold harmless Subtenant from, all damages, liabilities, losses, claims, attorneys’ fees, costs and expenses to the extent arising from the gross negligence or willful
misconduct of Sublandlord or its agents, contractors, licensees or invitees, or to the extent arising from a breach of Sublandlord’s obligations or representations under this Sublease or the Master Lease. 

Subtenant’s and Sublandlord’s obligations pursuant to the foregoing indemnities set forth in this
Section 12 shall survive the expiration or earlier termination of this Sublease. 

13.    Sublandlord’s Obligations under the Master Lease. Sublandlord agrees that Subtenant shall be
entitled to receive the benefit of all services and repairs to be provided by Master Landlord to Sublandlord under the Master Lease, as and to the extent that the same are actually provided by Master Landlord. Notwithstanding any provision of the
California Civil Code or any similar or successor laws to the contrary, Subtenant understands that it shall not make repairs at Sublandlord’s or Master Landlord’s expense or by Rent offset. Subtenant agrees that it shall look solely to
Master Landlord for all such services and shall not, under any circumstances, seek nor require Sublandlord to perform any of such services, nor shall Subtenant make any claim upon Sublandlord for any damages that may arise by reason of Master
Landlord’s default under the Master Lease; provided, however, that Sublandlord agrees to cooperate in good faith with Subtenant, in enforcing Sublandlord’s rights under the Master Lease for the services and repairs to be provided by Master
Landlord under the Master Lease; provided, however, Sublandlord shall not be required to incur any costs in cooperating except to the extent Subtenant agrees to pay any third party,
out-of-pocket costs reasonably incurred by Sublandlord. Any condition resulting from a default by Master Landlord shall not constitute as between Sublandlord and
Subtenant an eviction, actual or constructive, of Subtenant, and no such default shall excuse Subtenant from the performance or observance of any of its obligations to be performed or observed under this Sublease, or entitle Subtenant to receive any
reduction in or abatement of the Rent provided for in this Sublease, unless and only to the extent that Sublandlord is similarly excused from such performance or observance of such obligations under 


  
 9 














 
the Master Lease or to the extent Sublandlord is similarly entitled to receive any reduction in or abatement of rent under the Master Lease. In furtherance of the foregoing, Subtenant does hereby
waive any cause of action and any right to bring any action against Sublandlord by reason of any act or omission of Master Landlord under the Master Lease. Sublandlord covenants and agrees with Subtenant that Sublandlord will pay all Basic Rent and
Additional Rent payable by Sublandlord pursuant to the Master Lease to the extent that failure to perform the same would adversely affect Subtenant’s use or occupancy of the Sublease Premises. Sublandlord shall not do, nor permit to be done,
any act or thing that is, or with notice or the passage of time would be, a default under this Sublease or the Master Lease. Subtenant hereby waives any and all rights under and benefits of Sections 1932(1) and 1932(2), Section 1933(4), and
Sections 1941 and 1942 of the California Civil Code, or any similar or successor laws now or hereafter in effect. The provisions of this Section 13 shall survive the expiration or earlier termination of this Sublease.
Sublandlord shall not terminate or take any actions giving rise to a termination right under the Master Lease, amend or waive any provisions under the Master Lease or make any elections, exercise any right or remedy or give any consent or approval
under the Master Lease without, in each instance, Subtenant’s prior written consent. Following a casualty, if this Sublease is not terminated and to the extent of any insurance proceeds actually received by Sublandlord in connection with the
same, Sublandlord shall restore any improvements that Sublandlord installed in the Sublease Premises, to the extent such restoration is not the responsibility of Master Landlord under the Master Lease. Sublandlord represents and warrants that
(a) to the best of Sublandlord’s knowledge, the Master Lease is in full force and effect, (a) there exists under the Master Lease no default by Sublandlord or, to the best of Sublandlord’s knowledge, Master Landlord, nor to the
best of Sublandlord’s knowledge has there occurred any event which, with the giving of notice or passage of time or both, could constitute such a default by Sublandlord or Master Landlord under the Master Lease, and (c) the copy of the
Master Lease attached hereto as Exhibit A is a true, correct and complete copy of the Master Lease. 

14.    Default. Subtenant shall be in default under this Sublease if it or its agents breach, default or
fail to perform any obligation of this Sublease and/or any obligation of the Master Lease, as incorporated herein, required to be performed by Subtenant hereunder or thereunder. In the event of any such default, Sublandlord shall be entitled to all
the rights, benefits and privileges of the Master Landlord under the Master Lease, as incorporated herein, as it pertains to Subtenant’s, performance of the obligations under the Master Lease, together with any and all other remedies available
to Sublandlord at law or in equity. Any notice of default by Sublandlord to Subtenant shall be in lieu of, and not in addition to, the statutory notice required by Section 1161 of the California Civil Code, and any such notice shall expressly
replace and satisfy the requirements of Section 1162 of the California Civil Code. On termination of this Sublease due to the occurrence of any default by Subtenant, Sublandlord shall further be entitled to recover from Subtenant the
unamortized portion of the Abated Rent which Subtenant was not obligated to pay during the Base Rent Abatement Period, and such amount shall be payable by Subtenant to Sublandlord within five (5) days of Sublandlord’s written demand
therefore. Anything contained in any provision of this Sublease to the contrary notwithstanding, Subtenant agrees, with respect to the Sublease Premises, to comply with and remedy any default in this Sublease or the Master Lease, as incorporated
herein, which is Subtenant’s obligation to cure, within the period allowed to Sublandlord under the Master Lease, as incorporated herein, even if such time period is shorter than the period otherwise allowed therein (by no more than one
(1) business day) due to the fact that notice of default from Sublandlord to Subtenant is given after the corresponding notice of default from Master Landlord to Sublandlord. Sublandlord agrees to forward to Subtenant, within one
(1) business day of receipt thereof by Sublandlord, a copy of each notice received by Sublandlord in its capacity as Tenant under the Master Lease. Subtenant agrees to forward to Sublandlord, promptly upon receipt thereof, copies of any notices
received by Subtenant from Master Landlord or from any governmental authorities. In the event that Sublandlord defaults in the performance or observance of any of Sublandlord’s remaining obligations under the Master Lease or fails to perform
Sublandlord’s stated obligations under this Sublease, then Subtenant shall give Sublandlord written notice specifying in what manner Subtenant believes that Sublandlord has defaulted, and if such default shall not be cured by Sublandlord within
thirty (30) days thereafter (except that if such default cannot be cured within said thirty (30) day period, this period shall be extended for an additional reasonable time, provided that Sublandlord commences to cure such default within
such thirty (30) day period and proceeds diligently thereafter to effect such cure as quickly as possible), then Subtenant shall be entitled to cure such default and promptly collect from Sublandlord Subtenant’s reasonable expenses in so
doing (including, without 

  
 10 














 
limitation, reasonable attorneys’ fees and court costs) and, if Subtenant paid rent directly to Master Landlord, Subtenant may credit such amount against rent due under this Sublease.
Subtenant shall not be required, however, to wait the entire cure period described herein if earlier action is required to comply with the Master Lease or with any applicable governmental law, regulation or order. 

15.    Quiet Enjoyment; Estoppel Statements. So long as Subtenant pays all of the Rent due hereunder and
performs all of Subtenant’s other obligations hereunder within applicable notice and cure periods, Sublandlord shall do nothing to affect Subtenant’s right to peaceably and quietly have, hold and enjoy the Sublease Premises. Subtenant
shall, upon not less than ten (10) business days prior request by Sublandlord or Master Landlord or any first mortgagee of Master Landlord, execute, acknowledge and deliver to Sublandlord and Master Landlord or such mortgagee, as the case may
be, a statement in writing certifying that this Sublease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as modified and stating the modifications); that to Subtenant’s
knowledge Sublandlord is not in default and has fully performed its obligations hereunder; and the dates to which the Rent and any other charges have been paid in advance, all as and to the extent true, or alternatively with clarifications as deemed
reasonably appropriate by Subtenant. If Subtenant fails to timely deliver such statement or certificate, Subtenant shall be deemed to have accepted the statements in the certificate, and Subtenant agrees that any such statement or certificate may be
relied upon by such party. 
 16.    Holding Over. Subtenant has no right to occupy the Sublease Premises
or any portion thereof after the Sublease Expiration Date. In the event Subtenant or any party claiming by, through or under Subtenant holds over, Sublandlord may exercise any and all remedies available to it at law or in equity to recover
possession of the Sublease Premises, and to recover damages, including, without limitation, damages payable by Sublandlord to Master Landlord by reason of such holdover. Without limiting Sublandlord’s rights above, for each and every month or
partial month that Subtenant or any party claiming by, through or under Subtenant remains in occupancy of all or any portion of the Sublease Premises after the Sublease Expiration Date or after the earlier termination of this Sublease or of
Subtenant’s right to possession, Subtenant shall pay, as minimum and non-exclusive damages, and not as a penalty, monthly Base Rent at the rate set forth in Section 16 of the Master Lease, as
incorporated herein. The acceptance by Sublandlord of any lesser sum shall be construed as payment on account and not in satisfaction of damages for such holding over. 

17.    Tenant Improvements; Tenant Improvement Allowance. Sublandlord and Subtenant each acknowledge that
Subtenant desires to complete certain improvements to the Sublease Premises (the “Tenant Improvements”). In connection therewith, Subtenant agrees to comply with all of the provisions set forth for such improvements in
Section 8 of the Master Lease, as incorporated herein, and to submit to Sublandlord and to Master Landlord the plans, documents and other items described therein or otherwise required by Master Landlord thereunder. Subtenant further agrees to
obtain both Sublandlord’s and Master Landlord’s prior written approval of all plans for such work and improvements, all as and to the extent required by the Master Lease, prior to commencing any work. Subtenant understands, acknowledges
and agrees that it shall not be permitted to make any design changes which materially reduce the size of the Sublease Premises. 
 In
connection with Subtenant’s proposed improvements, Sublandlord agrees to make available to Subtenant a tenant improvement allowance in the total amount of $648,900, consisting of: (a) the remaining and unused Tenant Improvement
Allowance available to Sublandlord under the Master Lease, which amount Sublandlord confirms is $587,643.84 (calculated on the basis of $22.64 per sq. ft. of the Sublease Premises), and which amount shall be payable directly from
Master Landlord to Subtenant pursuant to such terms and conditions as Master Landlord shall require pursuant to the Master Lease (the “Master Lease Allowance”), and (b) upon Subtenant’s written notice to Sublandlord
confirming that Subtenant has spent ninety percent (90%) of the Master Lease Allowance, an additional amount of $61,256.16 (calculated on the basis of $2.39 per sq. ft. of the Sublease Premises) payable in one lump sum from Sublandlord to
Subtenant (collectively, the “TI Allowance”). As described in Section 20, the portion of the TI Allowance consisting of the Master Lease Allowance shall be paid by Master Landlord directly to Subtenant in
monthly installments within thirty (30) days of Subtenant’s delivery of invoices (and conditional lien waivers for its design and construction of the Tenant Improvements and unconditional lien waivers for work included in


  
 11 














 
previous draw requests), in an amount equal to the lesser of (i) a fraction of the amount requested by Subtenant in which the numerator is the amount of the Master Lease Allowance and the
denominator is the estimated cost of the Tenant Improvements and (ii) the amount of the remaining Master Lease Allowance. The TI Allowance shall be paid to and may be used by Subtenant only for purposes of Subtenant’s construction,
permitting and design costs associated with completion of the Tenant Improvements in the Subleased Premises (including Subtenant’s construction manager), all subject to Sublandlord’s and Master Landlord’s receipt, review and approval
of all items required by the Master Lease and this Sublease. Unless otherwise provided in Master Lessor’s consent, Subtenant will have until that date which is ten (10) months after the date of Master Landlord’s consent to this
Sublease within which to expend such funds and submit receipts, invoices and other evidence of such expenditures for payment of the TI Allowance, following which Subtenant acknowledges that Master Landlord has no further obligations with respect to
the unused portion of the Tenant Improvement Allowance and following which Subtenant agrees Sublandlord shall have no further obligation to pay any unused portion of the Tenant Improvement Allowance. In no event shall the TI Allowance apply as a
credit toward any Rent owing by Subtenant hereunder. Subtenant shall be responsible, at its sole cost and expense, for all expenses associated with completing the Tenant Improvements in excess of the TI Allowance. 

Subtenant shall be responsible for obtaining approvals for and performing and completing the Tenant Improvements in compliance with all
provisions of the Master Lease. Subtenant shall have the right to select the architects, engineers, contractors and subcontractors, including any specialty contractors, to construct and complete the Tenant Improvements, subject, however, to the
terms of the Master Lease and to Sublandlord’s and Master Landlord’s prior written approval. Subject to Master Landlord’s approval, Sublandlord hereby approves CAC Architects and Cody Brock Commercial Builders. PMA shall oversee the
design and construction of the interior improvements on behalf of the Master Landlord, and in connection therewith, PMA shall be paid a fee chargeable against the TI Allowance in the amount of 2.65% of the utilized TI Allowance and 2.0% of any work
managed by PMA on behalf of Subtenant, rather than the amount set forth in Section 8.3 of the Master Lease. 
 Subject to Master
Landlord’s reasonable approval, Subtenant shall be permitted to install within the Sublease Premises certain specialty equipment and trade fixtures for its laboratory space, which will include, by way of example, a generator, ATS, UPS and other
lab related facilities. 
 18.    Notices. All notices, demands, statements, designations, approvals or
other communications (collectively, “Notices”) given or required to be given by either party to the other hereunder or under the Master Lease or by law shall be in writing, shall be (i) sent by United States certified or
registered mail, postage prepaid, return receipt requested (“Mail”), (ii) delivered by a nationally recognized overnight courier, or (iii) delivered personally. Any Notice shall be sent, transmitted, or delivered, as the case
may be, to Subtenant at the appropriate address set forth below, or to such other place as Subtenant may from time to time designate in a Notice to Sublandlord, or to Sublandlord at the address set forth below, or to such other place as Sublandlord
may from time to time designate in a Notice to Subtenant, or to Master Landlord at the address set forth for Master Landlord under the Master Lease, or to such other place as Master Landlord may from time to time designate in a Notice to Sublandlord
(which Notice Sublandlord shall forward to Subtenant). Any Notice will be deemed given (a) three (3) business days after the date it is posted if sent by Mail, (b) the date the overnight courier delivery is made, or (c) the date
personal delivery is made. As of the date of this Sublease, any Notices to Sublandlord and Subtenant must be sent, transmitted, or delivered, as the case may be, to the following addresses:

19.    Brokers. Sublandlord and Subtenant represent and warrant to each other that, with the exception of
CBRE, Inc. representing the Sublandlord, and Savills-Studley representing the Subtenant, (collectively, “Brokers”), no brokers were involved in connection with the negotiation or consummation of this Sublease. Sublandlord agrees to
pay the commission of the Brokers pursuant to a separate agreement. Each party agrees to indemnify the other, and hold it harmless, from and against any and all claims, damages, losses, expenses and liabilities (including reasonable attorneys’
fees) incurred by said party as a result of a breach of this representation and warranty by the other party. 

20.    Consent of Landlord. Sublandlord and Subtenant each understand, acknowledge and agree that
Section 14 “Assignment and Subletting” of the Master Lease requires Sublandlord to obtain the prior written consent of Master Landlord to this Sublease. Sublandlord shall solicit Master Landlord’s consent to this Sublease,
which: (a) unless waived by both parties, must include Master Landlord’s agreement to fund the remaining portion of the Tenant Improvement Allowance under the Master Lease in the amount of $587,643.84 directly to Subtenant pursuant
to the provisions of Section 17 above or other reasonably acceptable mechanism, and (b) unless waived by Subtenant, must include Master Landlord’s (i) approval of Subtenant’s plans for the Tenant
Improvements attached hereto as Exhibit C, (ii) approval of Subtenant’s proposed architect and contractor, (iii) agreement that such Tenant Improvements do not need to be restored or removed at the end of the Term, and that no
bonds will be required, (iv) agreement that it will charge an oversight fee as described in Section 17 above rather than any amounts provided under Section 8 of the Master Lease,
(v) agreement that the release and waiver of subrogation in Section 10.5 of the Master Lease applies as between Subtenant and Master Landlord, (vi) agreement to the last sentence of
Section 10 above, and (vii) agreement that Master Landlord will insure and restore after a casualty (unless the Master Lease is terminated) the initial Tenant Improvements under the Master Lease, promptly following the
execution and delivery of this Sublease by Sublandlord and Subtenant. In the event Master Landlord’s written consent to this Sublease, inclusive of all of the items set forth in subparts (a) and (b) (i) through (vii) above (unless
waived as set forth above), has not been obtained within thirty (30) days 

  
 13 














 
after the execution hereof, then this Sublease may be terminated by either party hereto upon notice to the other prior to receipt of such consent, and upon such termination neither party hereto
shall have any further rights against or obligations to the other party hereto. Subtenant agrees that Sublandlord’s obtaining the Master Landlord’s prior written consent to this Sublease is a condition precedent to the commencement of this
Sublease and Sublandlord’s obligations hereunder. The full execution and delivery by Master Landlord, Sublandlord and Subtenant of Master Landlord’s consent form shall be deemed the satisfaction or waiver by both parties of the items set
forth in subparts (a) and (b) above. 
 21.    Termination of the Lease. If for any reason the term
of the Master Lease shall terminate prior to the Sublease Expiration Date, this Sublease shall automatically be terminated, and Sublandlord shall not be liable to Subtenant by reason thereof, unless said termination shall have been caused by the
default of Sublandlord under the Master Lease or this Sublease and said Sublandlord’s default was not as a result of a Subtenant’s default hereunder. 

22.    Limitation of Estate. Subtenant’s estate shall in all respects be limited to, and be construed
in a fashion consistent with, the estate granted to Sublandlord by Master Landlord. In the event Sublandlord is prevented from performing any of its obligations under this Sublease by a breach by Master Landlord of a term of the Master Lease, then
Sublandlord’s sole obligation in regard to its obligation under this Sublease shall be to use reasonable efforts, at Subtenant’s sole cost and expense, in diligently pursuing the correction or cure by Master Landlord of Master
Landlord’s breach. 
 23.    Entire Agreement, Amendment and Waiver. The recitals and all exhibits
attached hereto are incorporated herein by reference. References herein to this Sublease shall be deemed to include the recitals and all exhibits attached hereto. It is understood and acknowledged that there are no oral agreements between the
parties hereto affecting this Sublease and this Sublease supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Sublandlord to Subtenant
with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Sublease. This Sublease, and the exhibits and schedules attached hereto, contain all of the terms, covenants, conditions, warranties and
agreements of the parties relating in any manner to the rental, use and occupancy of the Sublease Premises and shall be considered to be the only agreements between the parties hereto and their representatives and agents. None of the terms,
covenants, conditions or provisions of this Sublease can be modified, deleted or added to except in writing signed by the parties hereto. All negotiations and oral agreements acceptable to both parties have been merged into and are included herein.
There are no other representations or warranties between the parties, and all reliance with respect to representations is based totally upon the representations and agreements contained in this Sublease. No failure or delay by any party hereto in
exercising any right, power or privilege hereunder, and no course of dealing between or among any of the parties, shall operate as a waiver of any such right, power or privilege. No waiver of any default on any one occasion shall constitute a waiver
of any subsequent or other default. No single or partial exercise of any such right, power or privilege shall preclude the further or full exercise thereof. 

24.    Severability. If any term or provision of this Sublease or the application thereof to any person or
circumstances shall, to any extent, be invalid and unenforceable, the remainder of this Sublease or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be
affected thereby and each term or provision of this Sublease shall be valid and be enforced to the fullest extent permitted by law. 

25.    Captions. Captions to the Sections in this Sublease are included for convenience only and are not
intended and shall not be deemed to modify or explain any of the terms of this Sublease. 
 26.    Further
Assurances. The parties hereto agree that each of them, upon the request of the other party, shall execute and deliver such further documents, instruments or agreements and shall take such further action that may be necessary or appropriate to
effectuate the purposes of this Sublease. 
 27.    Governing Law; Waiver of Jury Trial. This Sublease
shall be governed by, construed and interpreted in accordance with the laws of the State of California without regard to its choice of law 

  
 14 














 
rules. Subtenant agrees to and does waive all of its rights to a jury trial as set forth in Section 29.22 “Governing Law; WAIVER OF TRIAL BY JURY” of the Master Lease, which
provisions are incorporated herein by this reference. 
 28.    Attorneys’ Fees. The terms of
Section 29.21 of the Master Lease, as incorporated herein, shall apply as between Sublandlord and Subtenant. 

29.    Preparation of Sublease. Each party and its counsel have reviewed and revised (or requested revisions
of) this Sublease and have participated in the preparation of this Sublease, and therefore any rules of construction requiring that ambiguities are to be resolved against the party which drafted this Sublease shall not be applicable in the
construction and interpretation of this Sublease. 
 30.    Counterparts. This Sublease may be executed in
any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

31.    Authority. Subtenant hereby represents and warrants that Subtenant is a duly formed and existing
entity qualified to do business in the State of California and that Subtenant has full right an authority to execute and deliver this Sublease and that each person signing on behalf of Subtenant is authorized to do so.

(e.g., analytical test results, remediation report results, etc.). 
  

	 	5-6.	 For Lease renewals, are there any above or below ground pipelines on site used to transfer chemicals or wastes?



 ☐    Yes  ☐    No 

For new tenants, are installations of this type required for the planned
operations?    ☐    Yes  ☐    No 
 If YES to either
question in this section 5-6, please describe. 
  

	6.0	 ASBESTOS CONTAINING BUILDING MATERIALS 



Please be advised that an asbestos survey may have been performed at the Property. If provided, please review the information that identifies
the locations of known asbestos containing material or presumed asbestos containing material. All personnel and appropriate subcontractors should be notified of the presence of these materials, and informed not to disturb these materials. Any
activity that involves the disturbance or removal of these materials must be done by an appropriately trained individual/contractor. 
  

	7.0	 OTHER REGULATORY PERMITS/REQUIREMENTS 



 

	 	7-1.	 Does the operation have or require an industrial wastewater permit to discharge into the local National
Pollutant Discharge Elimination System (NPDES)? [Example: This applies when wastewater from equipment cleaning is routed through a pH neutralization system prior to discharge into the sanitary or lab sewer for certain pharmaceutical manufacturing
wastewater; etc.] Permits are obtained from the regional sanitation district that is treating wastewater. 



☐    Yes  ☒    No  ☐ No, but one will be prepared and submitted
to the Landlord property management company. 
 If so, please attach a copy of this permit or provide it later when it has been prepared.

  

	 	7-2.	 Has a Hazardous Materials Business Plan (HMBP) been developed for the site and submitted via the State of
California Electronic Reporting System (CERS)? [NOTE: The trigger limits for having to do this are ☐ 200 cubic feet if any one type of compressed gas(except for carbon dioxide and inert simple asphyxiant gases, which have a
higher trigger limit of 21 1,000 cubic feet); 21 55 gallons if any one type of hazardous chemical liquid; and 21500 pounds of any one type of hazardous chemical solid. So a full-sixe gas cylinder and a
260-liter of liquid nitrogen are triggers! Don’t forget the diesel fuel in a backup emergency generator if the diesel tank size is 21 55 gallons and it is permitted under the tenant (rather than under the
landlord).] NOTE: Each local Certified Unified Program Agency (CUPA) in California governs the HMBP process so start there. Examples: the CUPA for cities in San Mateo County is the County Environmental Health Department; the CUPA for the City of
Hayward, CA is the Hayward Fire Department; the CUPA for Mountain View is the Mountain View Fire Department; and, the CUPA for San Diego is the County of San Diego Hazardous Materials Division (HMD), 



☐    Yes  ☐    No  ☒ No, but one will be prepared and submitted,
and a copy will be provided to the landlord property management company. 
 If one has been completed, please attach a copy. Continue to
provide updated versions as they are completed. This is a legal requirement in that State law requires that the owner/operator of a business located on leased or rented real property shall notify, in writing, the owner of the property that the
business is subject to and is in compliance with the Hazardous Materials Business Plan requirements (Health and Safety Code Chapter 6.95 Section 25505.1). 

 

	 	7-3.	 NOTE: Please be advised that if you are involved in any tenant improvements that require a construction
permit, you will be asked to provide the local city with a Hazardous Materials Inventory Statement (HMIS) to ensure that your hazardous chemicals fall within the applicable Fire Code fire control area limits for the applicable construction occupancy
of the particular building. The HMIS will include much of the information listed in Section 2-2. Neither the landlord nor the landlord’s property management company expressly warrants that the
inventory provided in Section 2-2 will necessarily meet the applicable California Fire Code fire control area limits for building occupancy, especially in shared tenant occupancy situations. It is the
responsibility of the tenant to ensure that a facility and site can legally handle the intended operations and hazardous materials desired/ needed for its operations, but the landlord is happy to assist in this determination when possible.

	  	2	  	 Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with
water (e.g. white phosphorous, potassium, sodium)
  

	  	1	  	 Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene)

 

	  	0	  	 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium, N 2)
  

	Special	  	Ox	  	 Oxidizer, allows chemicals to burn without an air supply (e.g. potassium perchlorate, ammonium nitrate, hydrogen peroxide).

 

	  	W	  	 Reacts with water in an unusual or dangerous manner (e.g. caesium, sodium, sulfuric acid).

 

	  	SA	  	 Simple                     , gas. (e.g.
hydrogen, nitrogen, helium, neon, argon, krypton, xenon).
  

	  	COR	  	 Corrosive; strong acid or base (e.g. sulfuric acid, potassium hydroxide)

 

	  	ACID	  	 )
  

	  	ALK	  	 Alkaline
  

	  	BIO	  	 Biological hazard (e.g. flu virus, rabies virus)
  

	  	POI	  	 Poisonious (e.g.                     ,
alpha-                    )
  

	  	RAD	  	 Radioactive (e.g. plutonium,
cobalt-                    )
  

	  	CRYO	  	Cryogenic (e.g. liquid nitrogen)
