 1. PREMISES, BUILDING, PROJECT, AND COMMON AREAS 

1.1 Premises, Building, Project and Common Areas.  

1.1.1 The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises set
forth in Section 2.2 of the Summary (the “Premises”). The outline of the Premises is set forth in Exhibit A attached hereto. The outline of the “Building” and the
“Project,” as those terms are defined in Section 1.1.2 below, are further depicted on the Site Plan attached hereto as Exhibit A-1. The parties hereto agree
that the lease of the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration for this Lease to keep and perform each and all of such terms, covenants and
conditions by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of Exhibit A is to show the approximate location of the Premises only,
and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in
Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the “Project,” as that term is defined in Section 1.1.2, below. Except as specifically set forth in
this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the
Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the
foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and the Tenant Work Letter. The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were
at such time in good and sanitary order, condition and repair. For purposes of Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project, Building and Premises have not
undergone inspection by a Certified Access Specialist (CASp). 
 1.1.2 The Building and The Project. The
Premises are part of the building set forth in Section 2.1 of the Summary (the “Building”). The Building is part of an office/laboratory project currently known as “Torrey Pines Science
Park.” The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas, (ii) the land upon which the Building and the Common Areas are located, (iii) the other office/laboratory
buildings located at 11011, 11085 and 11077 North Torrey Pines Road, and the land upon which such adjacent office/laboratory buildings are located, and (iv) at Landlord’s discretion, any additional real property, areas, land, buildings or
other improvements added thereto outside of the Project and reasonably related to the Project. 
 1.1.3 Common
Areas. Tenant shall have the non-exclusive right to use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5 of this Lease, those
portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project (such areas, together with such other portions of the Project designated by Landlord, in its discretion, are
collectively referred to herein as the “Common Areas”). The Common Areas shall be maintained and operated by Landlord in a manner consistent with First Class Life Sciences Projects and the use thereof shall be subject to such
reasonable rules, regulations and restrictions as Landlord may make from time to time. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas,
provided that, in connection therewith, Landlord shall perform such closures, alterations, additions or changes in a commercially reasonable manner and, in connection therewith, shall use commercially reasonable efforts to minimize any material
interference with Tenant’s use of and access to the Premises. 
 1.1.4 Storage Space.  

1.1.4.1 In General. Commencing on the Lease Commencement Date, Landlord shall provide to Tenant, at no
additional cost (other than Direct Expenses to the extent allowed by the terms of Article 4 of this Lease), that certain approximate seventeen foot (17’) by seventeen foot (17’) storage area located on one of the subterranean
parking levels of the Building, as depicted on Exhibit A-2 attached hereto (the “Storage Space”). 

  
 4 

 1.1.4.2 Condition of Storage Space. The Storage Space shall
be delivered to Tenant in its existing, “as-is” condition, but in a broom clean condition with reasonably adequate lighting, and Tenant shall be fully responsible for repairing any damage to the
Storage Space solely resulting from or relating to Tenant’s use thereof. Tenant shall give prompt notice to Landlord in case of fire or accidents in or about the Storage Space or of defects therein or in the fixtures or equipment related
thereto. Tenant acknowledges and agrees that Landlord shall have no obligation to provide any security for the Storage Space. 

1.1.4.3 Other Terms. Tenant shall comply with Landlord’s reasonable rules and regulations from time to time
promulgated with respect to the use of the Storage Space. Tenant shall use the Storage Space for storage only and in no event shall Tenant maintain any “Hazardous Materials,” as that term is defined in Section 5.3
of this Lease, in the Storage Space. Further, Tenant’s use of the Storage Space shall at all times be consistent with the use of storage space in other First Class Life Sciences Projects. Tenant shall indemnify, defend protect and hold
Landlord harmless from and against any and all claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) arising out of or in connection with Tenant’s use of the Storage Space. In
addition, Tenant’s insurance obligations under the Lease shall pertain to Tenant’s use of the Storage Space. At any time during the term of Tenant’s lease of the Storage Space, upon not less than thirty (30) days’ notice to
Tenant, Landlord, at its sole cost and expense, shall have the right to relocate the Storage Space to another location in the Building, provided that the subject space contains at least the same square footage and similar improvements as the initial
storage space leased by Tenant hereunder, and is comparably accessible by Tenant as the initial storage space leased by Tenant hereunder. 

1.1.5 Condition of Building Systems. Notwithstanding anything set forth in
Section 1.1.1, above, to the contrary, Landlord shall cause the base Building mechanical, electrical and plumbing systems located in the internal core of the Building and which serve the Premises (the “Warrantied
Items”) to be in good working condition and repair upon the Lease Commencement Date. The foregoing shall not be deemed to require Landlord to replace any of the Warrantied Items, as opposed to repair any Warrantied Items. Provided Tenant
notifies Landlord prior to the first (1st) anniversary of the Lease Commencement Date, Landlord shall, at Landlord’s sole cost and expense (which shall not be deemed an “Operating
Expense,” as that term is defined in Article 4), repair or replace any portion of the Warrantied Item which was not in good working condition on the Lease Commencement Date, provided that the need to repair or replace was not caused
(A) by the misuse, misconduct, damage, destruction, omissions, and/or negligence of Tenant, its subtenants and/or assignees, if any, or any company which is acquired, sold or merged with Tenant (collectively, “Tenant Damage”),
or (B) by any modifications, Alterations or improvements constructed by or on behalf of Tenant. Landlord’s obligation pursuant to the immediately preceding sentence shall not extend to the costs of normal and customary preventive
maintenance relating to the Warrantied Item. To the extent repairs which Landlord is required to make pursuant to this Section 1.1.5 are necessitated in part by Tenant Damage, then Tenant shall reimburse Landlord for an
equitable proportion of the cost of such repair. If it is determined that the Warrantied Item was not in good working condition and repair as of the Lease Commencement Date, Landlord shall not be liable to Tenant for any damages, but, as
Tenant’s sole remedy, Landlord, at no cost to Tenant, shall promptly commence such work or take such other action as may be necessary to place the same in good working condition and repair, and shall thereafter diligently pursue the same to
completion. 
 1.2 Rentable Square Feet of Premises. The rentable square footage of the Premises is hereby
deemed to be as set forth in Section 2.2 of the Summary, and shall not be subject to measurement or adjustment during the Lease Term. 

1.3 Effectiveness of this Lease. Notwithstanding the full execution and delivery of this Lease by and between
Landlord and Tenant, the effectiveness of this Lease and Tenant’s lease of the Premises is expressly conditioned upon an affiliate of Landlord, HCP Torrey Pines, LLC (“Landlord Affiliate”), and Tenant entering into a
termination agreement which terminates Tenant’s lease of those certain premises located on the first (1st) and second (2nd) floors of that
certain building located at 11099 North Torrey Pines Road, La Jolla, California containing approximately 13,403 rentable square feet of space and commonly known as Suites 135, 270, 280 and 285 on or before the date that occurs ten (10) days
after the date set forth in Section 1 of the Summary, on the terms and conditions acceptable to Landlord Affiliate and Tenant (as determined in each of their sole discretion) (collectively, the
“Conditions”). In the event that 

  
 5 

 
any of the Conditions do not timely occur pursuant to the immediately preceding sentence, this Lease shall terminate and shall be null and void and without further force or effect. Landlord shall
have no liability whatsoever to Tenant relating to or arising from Landlord’s inability or failure to enter into the Termination Agreement. 

1.4 Right of First Offer. Landlord hereby grants to the Tenant originally named herein (the “Original
Tenant”) and any “Permitted Transferee Assignee,” as that term is defined in Section 14.8, below, a one-time right of first offer with respect to any space becoming
available in the Building that is not part of the initial Premises (the “First Offer Space”). Notwithstanding the foregoing, (A) in no event shall Tenant be entitled to lease any First Offer Space until after the expiration or
earlier termination of the existing leases (including any extensions thereof, whether pursuant to an express right or otherwise) of such First Offer Space, and (B) such first offer right of Tenant shall be subordinate to all existing rights of
third parties to lease such First Offer Space, including, without limitation, any expansion, first offer, first negotiation or other rights, regardless of whether such rights are executed strictly in accordance with their respective terms or
pursuant to lease amendment or new leases (all such tenants leasing the First Offer Space and third parties with existing rights, collectively, the “Superior Right Holders”). Tenant’s right of first offer shall be on the terms
and conditions set forth in this Section 1.4.  
 1.4.1 Procedure for Offer.
Landlord shall notify Tenant (the “First Offer Notice”) when and if the First Offer Space becomes available for lease to third parties (as reasonably determined by Landlord), provided that all Superior Right Holder have declined to
lease such space. Pursuant to such First Offer Notice, Landlord shall offer to lease to Tenant the First Offer Space. The First Offer Notice shall describe the space so offered to Tenant and the “Economic Terms,” as that term is defined in
Section 1.3.2 below, upon which Landlord is willing to lease such space to Tenant.. 
 1.4.2
Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of first offer with respect to the space described in the First Offer Notice, then within five (5) business days following delivery of the First Offer
Notice to Tenant, Tenant shall deliver notice (the “First Offer Exercise Notice”) to Landlord of Tenant’s election to exercise its right of first offer with respect to the entire space described in the First Offer Notice on the
terms contained in such notice. If Tenant does not notify Landlord within the five (5) business day period set forth above, then Landlord shall be free to lease the space described in the First Offer Notice to anyone to whom Landlord desires;
provided, however, if Landlord offers to lease the applicable First Offer Space (or any portion thereof) to a third party upon Economic Terms which, calculated on a “Net Equivalent Lease Rate” basis pursuant to the process set forth in
Exhibit G, attached hereto, are (in the aggregate) equal to or less than ninety-five percent (95%) of the Net Equivalent Lease Rate of the Economic Term set forth in Landlord’s final offer to Tenant for such First Offer Space,
then Landlord shall again offer such First Offer Space to Tenant on the Economic Terms offered to such third-party tenant by delivering another First Offer Notice to Tenant, which shall be subject to all of the terms and conditions of this
Section 1.4.2. For purposes hereof, the “Economic Terms” shall mean the following items: (i) base rent and free rent, including escalations thereto, expressed as a dollar amount per rentable square
foot, (ii) operating expense and tax protection such as a base year or expense stop, and (iii) all other monetary concessions (e.g., free rent, improvement allowances); provided that Landlord and Tenant acknowledge that the lease term
offered to such third party tenant may be different than the lease term of the First Offer Space for Tenant as set forth in Section 1.11.6, below. Notwithstanding anything to the contrary contained herein, Tenant must elect
to exercise its right of first offer, if at all, with respect to all of the First Offer Space offered by Landlord to Tenant, and Tenant may not elect to lease only a portion thereof. 

1.4.3 Construction In First Offer Space. Tenant shall take the First Offer Space in the configuration offered by
Landlord and in its then-existing “as is” condition. The construction of improvements in the First Offer Space shall comply with the terms of Article 8 of this Lease and other requirements Landlord may reasonably impose. The terms
of the Work Letter shall not apply to the construction of any improvements in the First Offer Space. 
 1.4.4 Amendment
to Lease. If Tenant timely exercises Tenant’s right to lease First Offer Space as set forth herein, then, within fifteen (15) days thereafter, Landlord and Tenant shall execute amendment to this Lease adding such First Offer Space
to the Premises upon the terms and conditions as set forth in the First Offer Notice therefor and this Section 1.4. Tenant shall commence payment of Rent for such First Offer Space, and the term of such First Offer Space
shall commence, upon the date of delivery of such First Offer Space to Tenant (the “First Offer Commencement Date”) and terminate on the date set forth in the First Offer Notice. 

1.4.5 Termination of Right of First Offer. The rights contained in this Section 1.4.5
shall 

  
 6 

 be personal to the Original Tenant and any Permitted Transferee, and may only be exercised
by the Original Tenant and such Permitted Transferee (and not any assignee, sublessee or other transferee of Tenant’s or such Permitted Transferee’s interest in the Lease) if the Original Tenant or such Permitted Transferee occupies the
entire Premises as of the date of the attempted exercise of the right of first offer by Tenant and as of the scheduled date of delivery of such First Offer Space to Tenant. The right of first offer granted herein shall terminate with respect to any
particular First Offer Space upon the failure by Tenant to exercise its right of first offer with respect to the First Offer Space so offered by Landlord. Tenant shall not have the right to lease First Offer Space, as provided in this
Section 1.4, if, as of the date of the attempted exercise of any right of first offer by Tenant, or, as of the scheduled date of delivery of such First Offer Space to Tenant, Tenant is in monetary or material non-monetary default under this Lease (beyond the applicable notice and cure period provided in this Lease) or Tenant has previously been in monetary or material non-monetary
default under this Lease (beyond the applicable notice and cure period provided in this Lease) during the prior twelve (12) month period. 
 2. LEASE
TERM; OPTION TERM 
 2.1 Lease Term. The terms and provisions of this Lease shall be effective as of the
date of this Lease. The term of this Lease (the “Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the
Summary (the “Lease Commencement Date”), and shall terminate on the date set forth in Section 3.3 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as
hereinafter provided. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term; provided, however, that the first (1st) Lease Year shall commence on the Lease Commencement Date and end on the last day of the month in which the first (1 st) anniversary of the Lease
Commencement Date occurs (or if the Lease Commencement Date is the first (1 st) day of a calendar month, then the first (1st) Lease Year shall
end on the day preceding the first (1st) anniversary of the Lease Commencement Date), and the second and each succeeding Lease Year shall commence on the first (1 st) day of the next calendar month; provided further that the last Lease Year shall end on the Lease Expiration Date. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the
form as set forth in Exhibit C, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within five (5) days of receipt thereof. Notwithstanding the foregoing, if
the Lease Commencement Date has not occurred on or before the date that occurs forty-five (45) days after the Anticipated Lease Commencement Date (the “Abatement Date”), then Base Rent shall be abated from and after the Lease
Commencement Date for one day for each day that occurs after the Abatement Date and before the Lease Commencement Date; provided, however, the Abatement Date shall be delayed by one (1) day for each day that the Lease Commencement Date is
delayed by an event of “Force Majeure” (as that term is defined in Section 29.16) or by a “Tenant Delay” (as that term is defined in Section 5.2 of the Tenant Work Letter). 

2.2 Option Term.  

2.2.1 Option Right. Landlord hereby grants to the Original Tenant, and any Permitted Transferee Assignee, one
(1) option to extend the Lease Term for a period of five (5) years (the “Option Term”), which option shall be irrevocably exercised only by written notice delivered by Tenant to Landlord not earlier than twelve
(12) months before the commencement of the Option Term and not later than ten (10) months before the commencement of the Option Term, provided that the following conditions (the “Option Conditions”) are satisfied:
(i) as of the date of delivery of such notice, Tenant is not in default under this Lease (beyond the expiration of any applicable notice and cure period expressly set forth in this Lease); (ii) as of the end of the Lease Term, Tenant is not in
default under this Lease (beyond the expiration of any applicable notice and cure period expressly set forth in this Lease); and (iii) Tenant has not previously been in default under this Lease (beyond the expiration of any applicable notice
and cure period expressly set forth in this Lease) more than twice during the immediately preceding twelve (12) month period. Landlord may, at Landlord’s option, exercised in Landlord’s sole and absolute discretion, waive any of the
Option Conditions in which case the option, if otherwise properly exercised by Tenant, shall remain in full force and effect. Upon the proper exercise of such option to extend, and provided that Tenant satisfies all of the Option Conditions (except
those, if any, which are waived by Landlord), the Lease Term, as it applies to the Premises, shall be extended for a period of five (5) years. The rights contained in this Section 2.2 shall be personal to Original
Tenant and any Permitted Transferee Assignee, and may only be exercised by Original Tenant or a Permitted Transferee Assignee (and not by any other assignee, sublessee or Transferee of Tenant’s interest in this Lease). 

2.2.2 Option Rent. The annual Rent payable by Tenant during the Option Term (the 

  
 7 

 “Option Rent”) shall be equal to the “Fair Rental Value,” as that
term is defined below, for the Premises as of the commencement date of the Option Term. The “Fair Rental Value,” as used in this Lease, shall be equal to the annual rent per rentable square foot (including additional rent and
considering any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants (pursuant to leases consummated within the twelve (12) month period preceding the first day of the Option Term),
are leasing non-sublease, non-encumbered, non-equity space which is not significantly greater or smaller in size than the subject
space, for a comparable lease term, in an arm’s length transaction, which comparable space is located in the “Comparable Buildings,” as that term is defined in this Section 2.2.2, below (transactions
satisfying the foregoing criteria shall be known as the “Comparable Transactions”), taking into consideration the following concessions (the “Concessions”): (a) rental abatement concessions, if any, being granted
such tenants in connection with such comparable space; (b) tenant improvements or allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject space,
such value to be based upon the age, condition, design, quality of finishes and layout of the improvements; and (c) other reasonable monetary concessions being granted such tenants in connection with such comparable space; provided, however,
that in calculating the Fair Rental Value, no consideration shall be given to any period of rental abatement, if any, granted to tenants in comparable transactions in connection with the design, permitting and construction of tenant improvements in
such comparable spaces. In connection with the determination of Fair Rental Value, the parties shall initially look to new, non-renewing, non-expanding transactions in
the Comparable Buildings; provided, however, if there are not enough new, non-renewal, non-expanding transactions in the Comparable Buildings to reasonably establish the
Fair Rental Value, then the parties may look to renewal and/or expansion transactions in the Comparable Buildings. The Fair Rental Value shall additionally include a determination as to whether, and if so to what extent, Tenant must provide Landlord
with financial security, such as a letter of credit or guaranty, for Tenant’s Rent obligations in connection with Tenant’s lease of the Premises during the Option Term. Such determination shall be made by reviewing the extent of financial
security then generally being imposed in Comparable Transactions from tenants of comparable financial condition and credit history to the then existing financial condition and credit history of Tenant (with appropriate adjustments to account for
differences in the then-existing financial condition of Tenant and such other tenants). The Concessions (A) shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of
such Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant, or (B) at
Landlord’s election, all such Concessions shall be granted to Tenant in kind. Notwithstanding the foregoing, during the Option Term, the Base Rent component of the Option Rent shall increase by three percent (3%) per annum on each anniversary
of the first (1 st) day of the Option Term; provided that such annual increases shall be taken into consideration in connection with the determination of Fair Rental Value. The term
“Comparable Buildings” shall mean the Building and those other First Class Life Sciences Projects located in the Torrey Pines market area of San Diego, California that are comparable in age (based on the date of original
construction or the latest major renovation) location, quality of construction, services and amenities. 
 2.2.3
Determination of Option Rent. In the event Tenant timely and appropriately exercises an option to extend the Lease Term, Landlord shall notify Tenant of Landlord’s determination of the Option Rent within thirty (30) days of
receipt of Tenant’s notice to extend. If Tenant, on or before the date which is thirty (30) days following the date upon which Tenant receives Landlord’s determination of the Option Rent, in good faith objects to Landlord’s
determination of the Option Rent, then Landlord and Tenant shall attempt to agree upon the Option Rent using their best good-faith efforts. If Landlord and Tenant fail to reach agreement on or before the date that occurs ninety (90) days before
the Lease Expiration Date (the “Outside Agreement Date”), then each party shall make a separate determination of the Option Rent, as the case may be, within five (5) days, and such determinations shall be submitted to
arbitration in accordance with Sections 2.2.3.1 through 2.2.3.8, below. If Tenant fails to object to Landlord’s determination of the Option Rent within the time period set forth herein, then Tenant shall be deemed to have accepted
Landlord’s determination of Option Rent. 
 2.2.3.1 Landlord and Tenant shall each appoint one arbitrator who shall be,
at the option of the appointing party, a real estate broker, appraiser or attorney who shall have been active over the five (5) year period ending on the date of such appointment in the leasing or appraisal, as the case may be, of life science
properties in San Diego, California. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Option Rent is the closest to the actual Option Rent, taking into account the
requirements of Section 2.2.2 of this Lease, as determined by the arbitrators. Each such arbitrator shall be appointed within fifteen (15) days after the Outside Agreement Date. Landlord and Tenant may consult with
their selected arbitrators prior to appointment and may select an arbitrator who is favorable to their respective positions. The arbitrators so selected by Landlord and Tenant shall be deemed “Advocate Arbitrators.” 

  
 8 

 2.2.3.2 The two (2) Advocate Arbitrators so appointed shall be
specifically required pursuant to an engagement letter within ten (10) days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator (“Neutral Arbitrator”) who shall
be qualified under the same criteria set forth hereinabove for qualification of the two Advocate Arbitrators, except that neither the Landlord or Tenant or either parties’ Advocate Arbitrator may, directly or indirectly, consult with the
Neutral Arbitrator prior or subsequent to his or her appearance. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel. 

2.2.3.3 The three arbitrators shall, within thirty (30) days of the appointment of the Neutral Arbitrator, reach a
decision as to whether the parties shall use Landlord’s or Tenant’s submitted Option Rent, and shall notify Landlord and Tenant thereof. 

2.2.3.4 The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant. 

2.2.3.5 If either Landlord or Tenant fails to appoint an Advocate Arbitrator within fifteen (15) days after the Outside
Agreement Date, then either party may petition the presiding judge of the Superior Court of San Diego County to appoint such Advocate Arbitrator subject to the criteria in Section 2.2.3.1 of this Lease, or if he or she

 4.2.6 “Tenant’s Share”
shall mean the percentage set forth in Section 6 of the Summary. 
 4.3 Allocation of Direct
Expenses. The parties acknowledge that the Building is a part of a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the Building and the other
buildings in the Project. Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consist of Operating Expenses and tax Expenses) are determined annually for the Project as a whole, and a portion of the
Direct Expenses, which portion shall be determined by Landlord on an equitable basis, shall be allocated to the Building (as opposed to other buildings in the Project). Such portion of Direct Expenses allocated to the Building shall include all
Direct Expenses attributable solely to the Building and an equitable portion of the Direct Expenses attributable to the Project as a whole, and shall not include Direct Expenses attributable solely to other buildings in the Project. 

4.4 Calculation and Payment of Additional Rent. Tenant shall pay to Landlord, in the manner set forth in
Section 4.4.1, below, and as Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year. Notwithstanding anything to the contrary contained in this Article 4, the aggregate “Controllable
Expenses,” as that term is defined below, included in Direct Expenses in any Expense Year after the first (1st) Expense Year shall never be increased to an amount in excess of the amount that such Controllable Expenses would currently be had
they increased, from the initial amount for such Controllable Expenses set forth in the first (1st) Expense Year, at a cumulative rate of five percent (5%) per Expense Year. For purposes of this Section 4.4,
“Controllable Expenses” shall mean all Direct Expenses except: (i) Tax Expenses and any and all assessments, including assessment districts and government-mandated charges with respect to the Building or Project, or any part
thereof; (ii) insurance carried by Landlord; and (iii) costs of utilities, including, without limitation, electricity, water, HVAC and sewer charges, utility surcharges and assessments, and refuse removal. The terms Controllable Expenses
shall also exclude the costs of capital alterations, capital additions, capital improvements, capital repairs and capital replacements to the extent included in Operating Expenses pursuant to the definition in
Section 4.2.4, above; and costs to repair caused by any casualty, vandalism or events of Force Majeure. 

4.4.1 Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall endeavor to give to Tenant
within one hundred fifty (150) days following the end of each Expense Year, a statement (the “Statement”) which shall state the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the
amount of Tenant’s Share of Direct Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due, the full amount of Tenant’s Share of
Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Direct Expenses,” as that term is defined in Section 4.4.2, below, and if Tenant paid more as
Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Tenant shall receive a credit in the amount of Tenant’s overpayment against Rent next due under this Lease. The failure of Landlord to timely furnish the
Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made of
Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, Tenant shall pay to Landlord such amount within thirty (30) days following receipt of Landlord’s request therefor, and if Tenant paid more as
Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this
Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term, provided that, other than Tax Expenses and costs incurred for utilities, Tenant shall not be responsible for Tenant’s Share of any
Operating Expenses which are first billed to Tenant more than two (2) calendar years after the end of the Expense Year to which such Operating Expenses relate. 

4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall endeavor to give Tenant a yearly
expense estimate statement (the “Estimate Statement”) which shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Direct Expenses for the then-current Expense Year shall be
and the estimated Tenant’s Share of Direct Expenses (the “Estimated Direct Expenses”). The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights
to collect any Estimated Direct Expenses under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to the extent necessary. Thereafter, Tenant

  
 13 

 
shall pay, with its next installment of Base Rent due, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of
this Section 4.4.2). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new
Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12)
of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant. 
 4.5
Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall be liable for and shall pay ten (10) days before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any other personal
property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property
is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless
of the validity thereof but only under proper protest if requested by Tenant, Tenant shall within thirty (30) days following receipt of written demand repay to Landlord the taxes so levied against Landlord or the proportion of such taxes
resulting from such increase in the assessment, as the case may be. 
 4.6 Landlord’s Books and Records.
Notwithstanding anything to the contrary contained in this Lease, if, within ninety (90) days after receipt of a Statement by Tenant, Tenant (i) reasonably disputes any amounts set forth in any Statement described above in this Article
4, and (ii) is not then in monetary or material non-monetary default under this Lease (beyond the expiration of any applicable notice and cure period expressly set forth in this Lease), then Tenant
shall have the right to cause Landlord’s books and records to be audited by a firm of certified public accountants reasonably approved by Landlord, at no cost or expense to Landlord, which has prior experience in the review of financial
statements and which shall not have provided primary accounting services to Tenant within the immediately preceding three (3) year period and which shall not be retained by Tenant on a contingency fee basis; provided, however, Tenant shall not
have the right to perform any such audit more than one (1) time for any Expense Year during the Lease Term. Any audit conducted by or on behalf of Tenant shall be completed in a diligent manner and timely manner (but in any event within two
(2) months after Tenant initially disputes the applicable Statement) and shall be performed at Landlord’s office during Landlord’s normal business hours and in a manner so as to minimize interference with Landlord’s business
operations. Landlord shall have no obligation and Tenant shall have no right to make photocopies of any of Landlord’s ledgers, invoices or other items. Tenant agrees to keep, and to cause Tenant’s accountant and its employees to keep, all
information revealed by any audit of Landlord’s books and records strictly confidential and not to disclose any such information or permit any such information to be disclosed to anyone other than Landlord, unless compelled to do so by a court
of law or any Applicable Law, statute, code, rule or regulation, and Tenant and its accountant and their employees shall sign a confidentiality agreement reflecting such confidentiality. Tenant’s audit shall be limited to an on-site review of Landlord’s general ledger of accounts and supporting documentation. If after such audit, Landlord and Tenant dispute the results of such audit, at Tenant’s request, a certified public
accounting firm selected by Landlord, and reasonably approved by Tenant, shall, at Tenant’s cost, conduct an audit of the relevant Direct Expenses. The amounts payable under this Section 4.6 by Landlord to Tenant or by
Tenant to Landlord, as the case may be, will be appropriately adjusted on the basis of such audit. If such audit discloses an overstatement of Direct Expenses in excess of five percent (5%) for such Expense Year, Landlord shall reimburse Tenant for
the reasonable cost of both audits; otherwise the cost of such audits shall be borne by Tenant. Tenant agrees that this Section 4.6 shall be the sole method to be used by Tenant to dispute the amount of any Direct Expenses
payable by Tenant pursuant to the terms of this Lease, and Tenant hereby waives any other rights at law or in equity relating thereto. 
 5. USE OF
PREMISES 
 5.1 Permitted Use. Tenant shall use the Premises solely for the Permitted Use set forth in
Section 7 of the Summary and Tenant shall not use or permit the Premises or the Project to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which may be withheld in

Building, or injure or annoy them or use or allow the Premises to be used for any improper, unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. Tenant shall comply with, and
Tenant’s rights and obligations under the Lease and Tenant’s use of the Premises shall be subject and subordinate to, all recorded easements, covenants, conditions, and restrictions now or hereafter affecting the Project.

environmental condition of the Premises to any Person (other than Tenant’s consultants, attorneys, property managers and employees that have a need to know such information), including any governmental authority, without the prior written
consent of Landlord. In the event Tenant reasonably believes that disclosure is compelled by applicable law, it shall provide Landlord ten (10) days’ advance notice of disclosure of confidential information so that Landlord may attempt to

 6. SERVICES AND UTILITIES 

6.1 Standard Tenant Services. Landlord shall provide the following services on all days (unless otherwise stated
below) during the Lease Term. 
 6.1.1 Subject to limitations imposed by all governmental rules, regulations and guidelines
applicable thereto, Landlord shall provide heating, ventilation and air conditioning (“HVAC”) when necessary for normal comfort for normal office use in the office areas of the Premises from 7:00 A.M. to 6:00 P.M. Monday through

seven (7) days a week. Tenant shall cooperate fully with Landlord at all times and abide by all reasonable regulations and requirements that Landlord may reasonably prescribe for the proper functioning and protection of the HVAC, electrical,
mechanical and plumbing systems. 
 6.1.2 Electricity is separately metered (or
sub-metered) at the Premises and shall be paid directly by Tenant to the applicable utility provider. If electricity is separately sub-metered (as opposed to separately
metered), then Tenant shall pay to Landlord the cost of such utilities based on such sub-meter, including an administrative charge for Landlord’s supervision and reimbursement for any penalties for usage
or other surcharges imposed by any utility company. Within twenty (20) days after receipt of Landlord’s statement of apportionment or statement setting forth the charges payable by Tenant, Tenant shall pay to Landlord, as Additional Rent,
the cost of 

  
 18 

 
such electrical services so apportioned or so provided by Landlord. Notwithstanding anything to the contrary set forth herein, to the extent the Premises generates electricity demand on a shared
resource (e.g. electricity for the central plant), the cost of such electricity shall be allocated to Tenant on a pro rata basis or other reasonable basis consistent with commercial reasonable property management practices. 

6.1.3 Landlord shall not provide janitorial services for the Premises. Tenant shall be solely responsible for performing all
janitorial services and other cleaning of the Premises, all in compliance with applicable laws. The janitorial and cleaning of the Premises shall be adequate to maintain the Premises in a manner consistent with First Class Life Sciences
Projects. 
 Tenant shall cooperate fully with Landlord at all times and abide by all regulations and requirements that
Landlord may reasonably prescribe for the proper functioning and protection of the HVAC, electrical, mechanical and plumbing systems. 

6.2 Additional Services Landlord shall have the exclusive right, but not the obligation, to provide any
additional services which may be required by Tenant, including, without limitation, locksmithing, lamp replacement, additional janitorial service, and additional repairs and maintenance. If Tenant requests any such additional services, then Tenant
shall pay to Landlord the cost of such additional services, including Landlord’s standard fee for its involvement with such additional services, within thirty (30) days following receipt of written demand for same. 

6.3 Interruption of Use. Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent
(except as set forth in Section 19.5.2, below) or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity
thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel
at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause; and such failures or delays or
diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent (except as set forth in Section 19.5.2, below) or performing
any of its obligations under this Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, including, without limitation, loss of
profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6. 

7. REPAIRS 
 7.1
Tenant Repair Obligations. Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures, furnishings, and systems and equipment therein (including, without limitation, plumbing fixtures and
equipment such as dishwashers, garbage disposals, and insta-hot dispensers), and the floor or floors of the Building on which the Premises are located, in good order, repair and condition at all times during
the Lease Term. In addition, Tenant shall, at Tenant’s own expense, but under the supervision and subject to the prior approval of Landlord, and within any reasonable period of time specified by Landlord, promptly and adequately repair all
damage to the Premises and replace or repair all damaged, broken, or worn fixtures and appurtenances, except for damage caused by ordinary wear and tear or beyond the reasonable control of Tenant; provided however, that, at Landlord’s option,
or if Tenant fails to make such repairs, Landlord may, but need not, make such repairs and replacements, and Tenant shall pay Landlord the cost thereof, including a percentage of the cost thereof (to be uniformly established for the Building and/or
the Project) sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and replacements within thirty (30) days following receipt of
written demand for same. 
 7.2 Landlord Repair Obligations. Notwithstanding the foregoing, Landlord shall be
responsible for repairs to the exterior walls, foundation, slab and roof (including roof membrane) of the Building, the structural portions of the floors of the Building, the base Building systems and equipment located in the internal core of
the Building (the “Building Systems”) and Common Areas, and exterior utilities and plumbing to the Building, except to the extent that such repairs are required due to the negligence or willful misconduct of Tenant; provided,
however, that if such repairs are due to the negligence or willful misconduct of Tenant, Landlord shall nevertheless make such repairs at Tenant’s expense, or, if covered by Landlord’s insurance, Tenant shall only be obligated to pay any
deductible in connection therewith. Subject to the terms of Article 27, below, Landlord may, but shall not be required to, enter the Premises at all reasonable times to make such repairs, alterations, improvements or additions to the Premises
or to the Project or to any equipment located in the Project as Landlord shall desire or deem necessary or as Landlord may be required to do by governmental or quasi-governmental authority or court order or decree. Tenant hereby waives any and all
rights under 

  
 19 

 
and benefits of subsection 1 of Section 1932 and Sections 1941 and 1942 of the California Civil Code or under any similar law, statute, or ordinance now or hereafter in effect. 

8. ADDITIONS AND ALTERATIONS 

8.1 Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions or
changes to the Premises or any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which
consent shall be requested by Tenant not less than thirty (30) days prior to the commencement thereof, and which consent shall not be unreasonably withheld by Landlord, provided it shall be deemed reasonable for Landlord to withhold its consent
to any Alteration which adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the Building. Notwithstanding the foregoing, Tenant shall be permitted to make Alterations following ten
(10) business days’ notice to Landlord, but without Landlord’s prior consent, to the extent that such Alterations (i) do not affect the building systems or equipment, (ii) are not visible from the exterior of the Building,
and (iii) cost less than $50,000.00 for a particular job of work. The construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8.  

8.2 Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations or
repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that, subject to the terms of Section 8.5, below,
upon Landlord’s request, Tenant shall, at Tenant’s expense, remove such Alterations upon the expiration or any early termination of the Lease Term. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike
manner, in conformance with any and all applicable federal, state, county or municipal laws, rules and regulations and pursuant to a valid building permit (if required), issued by the city in which the Building is located (or other applicable
governmental authority). Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the
workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas. Upon completion of any Alterations (or repairs), Tenant shall deliver to Landlord final lien waivers from all contractors,
subcontractors and materialmen who performed such work. In addition to Tenant’s obligations under Article 9 of this Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of
the Recorder of the County of San Diego in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project construction manager a reproducible copy of the “as
built” drawings of the Alterations as well as all permits, approvals and other documents issued by any governmental agency in connection with the Alterations. 

8.3 Payment for Improvements. If Tenant orders any work directly from Landlord, Tenant shall pay to Landlord an
amount equal to three percent (3%) of the cost of such work to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlord’s involvement with such work. If Tenant does not order any work
directly from Landlord, Tenant shall reimburse Landlord for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with
Landlord’s review of such work. 
 8.4 Construction Insurance. In addition to the requirements of
Article 10 of this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant carries “Builder’s All Risk” insurance in
an amount approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article
10 of this Lease immediately upon completion thereof. In addition, Tenant’s contractors and subcontractors shall be required to carry (i) Commercial General Liability Insurance in an amount approved by Landlord, with Landlord, and, at
Landlord’s option, Landlord’s property manager and project manager, as additional insureds in an amount approved by Landlord, and otherwise in accordance with the requirements of Article 10 of this Lease, and (ii) workers
compensation insurance with a waiver of subrogation in favor of Landlord. In the event an Alteration is reasonably anticipated to cost in excess of $50,000, then Landlord may, in its reasonable discretion, if consistent with the requirements of the
landlords of First Class Life Science Projects in connection with tenants performing similar construction projects, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount
sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee. For purposes of determining the cost of an Alteration, work done in phases or stages shall be considered
part of the same Alteration, and any Alteration shall be deemed to include all trades and materials involved in accomplishing a particular result. 

  
 20 

 8.5 Landlord’s Property. All Alterations, improvements,
fixtures, equipment and/or appurtenances which may be installed or placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and shall be and become the property of Landlord and remain in place at the Premises following
the expiration or earlier termination of this Lease. Notwithstanding the foregoing, Landlord may, by written notice to Tenant prior to the end of the Lease Term, or given following any earlier termination of this Lease, require Tenant, at
Tenant’s expense, to remove any Alterations and/or improvements and/or systems and equipment within the Premises and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the Premises to a
building standard tenant improved condition as determined by Landlord, provided further, however, notwithstanding the foregoing, upon request by Tenant at the time of Tenant’s request for Landlord’s consent to any Alteration or
improvement, Landlord shall notify Tenant whether the applicable Alteration or improvement will be required to be removed pursuant to the terms of this Section 8.5. If Tenant fails to complete any required removal and/or to
repair any damage caused by the removal of any Alterations and/or improvements and/or systems and equipment in the Premises and return the affected portion of the Premises to a building standard tenant improved condition as reasonably determined by
Landlord, Landlord may do so and may charge the cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the
installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination of this Lease. 

9. COVENANT AGAINST LIENS Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work
performed, materials furnished or obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable
attorneys’ fees and costs) arising out of same or in connection therewith. Tenant shall give Landlord notice at least ten (10) business days prior to the commencement of any such work on the Premises (or such additional time as may
be necessary under applicable laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility (to the extent applicable pursuant to then applicable laws). Tenant
shall remove any such lien or encumbrance by bond or otherwise within ten (10) business days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being
responsible for investigating the validity thereof. 
 10. INSURANCE 

10.1 Indemnification and Waiver. Tenant hereby assumes all risk of damage to property or injury to persons in,
upon or about the Premises from any cause whatsoever and agrees that Landlord, its partners, subpartners and their respective officers, agents, servants, employees, lenders, any property manager and independent contractors (collectively,
“Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other
persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all claims, loss, cost, damage, injury, expense and liability (including without limitation court costs and reasonable
attorneys’ fees) incurred in connection with or arising from any cause in, on or about the Premises, any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of the contractors, agents, servants,
employees, invitees, guests or licensees of Tenant or any such person, in, on or about the Project, either prior to, during, or after the expiration of the Lease Term, provided that the terms of the foregoing indemnity shall not apply if and from
the time that a final adjudication has resulted in a finding of willful misconduct or negligence of Landlord. Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant’s occupancy of
the Premises, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including without limitation, its reasonable professional fees such as reasonable appraisers’, accountants’ and attorneys’ fees. The provisions
of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection with any event occurring prior to such expiration or termination. Landlord
shall be liable for, and shall indemnify, defend, protect and hold Tenant and Tenant’s partners, officers, directors, employees, agents, successors and assigns harmless from and against any and all claims, loss, cost, damage, injury, expense
and liability (including without limitation court costs and reasonable attorneys’ fees) arising or resulting from the gross negligence or willful misconduct of Landlord or any of Landlord’s Parties. 

10.2 Tenant’s Compliance With Landlord’s Property Insurance. Landlord shall insure the Building during
the Lease Term against loss or damage under an “all risk” property insurance policy. Such coverage shall be in such amounts, from such companies, and on such other terms and conditions, as Landlord may from time to time reasonably
determine. Additionally, at the option of Landlord, such insurance coverage may include the risks of earthquakes and/or flood damage and additional hazards, a rental loss endorsement and one or more loss payee endorsements in favor of the holders of
any mortgages or deeds of trust encumbering the interest of Landlord in the 

  
 21 

 
Building or the ground or underlying lessors of the Building, or any portion thereof. Tenant shall, at Tenant’s expense, comply with all insurance company requirements pertaining to the use
of the Premises. If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all
rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body. Tenant shall also provide Landlord and Landlord’s insurer(s) with such information
regarding the use of the Premises and any damage to the Premises as they may require in connection with the placement of insurance for the Premises or the adjusting of any losses to the Premises. 

10.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the following amounts.

term is defined in the Tenant Work Letter, and any other improvements which exist in the Premises as of the Lease Commencement Date (excluding the Base Building) (the “Original Improvements”), and (iii) all other improvements,

depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include coverage for damage or other loss caused by fire or other peril including, but
not limited to, vandalism and malicious mischief, theft, water damage of any type, including sprinkler leakage, bursting or stoppage of pipes, and explosion.

no event limit the liability of Tenant under this Lease. Such insurance shall (i) name Landlord, its subsidiaries and affiliates, its property manager (if any) and any other party the Landlord reasonably so specifies, as an additional insured
or loss payee with respect to insurance under Section 10.3.2(ii) and (iii), including Landlord’s managing agent, if any; (ii) be issued by an insurance company having a rating of not less than A:IX in Best’s Insurance Guide or
which is otherwise acceptable to Landlord and licensed to do business in the State of California; (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance required of Tenant; (v) be in form and content reasonably acceptable to Landlord; and (vi) provide that said insurance shall not be canceled or coverage changed unless
thirty (30) days’ prior written notice shall have been given to Landlord and any mortgagee of Landlord (unless such cancellation is the result of non-payment of premiums). Tenant shall deliver said
policy or policies or certificates thereof to Landlord on or before the Lease Commencement Date and at least ten (10) days before the expiration dates thereof. In the event Tenant shall fail to procure such insurance, or to deliver such
policies or certificate, Landlord may, at its option, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within thirty (30) days after Tenant’s receipt of bills therefor. 

10.5 Subrogation. Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their
respective insurance carriers in the event of a property or business interruption loss to the extent that such coverage is agreed to be provided hereunder. The parties each hereby waive all rights and claims against each other for such

  
 22 

 
losses, and waive all rights of subrogation of their respective insurers, provided such waiver of subrogation shall not affect the right to the insured to recover thereunder. The parties agree
that their respective insurance policies do now, or shall, contain the waiver of subrogation. 
 10.6 Additional
Insurance Obligations. Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such
other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably requested by Landlord or Landlord’s lender, but in no event in excess of the amounts
and types of insurance then being required by landlords of buildings comparable to and in the vicinity of the Building. 
 11. DAMAGE AND DESTRUCTION

 11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to
the Premises resulting from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays
for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11, restore the Base Building and such Common Areas. Such restoration shall be to substantially the same
condition of the Base Building and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the Building or Project or any other modifications to the
Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the Premises shall not be materially impaired. Upon the occurrence of any damage to the Premises, upon notice (the
“Landlord Repair Notice”) to Tenant from Landlord, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under
Section 10.3 of this Lease, and Landlord shall repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall return such Tenant Improvements and Original
Improvements to their original condition; provided that if the cost of such repair by Landlord exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier (including by taking into account any deductible or
self-insured retention), as assigned by Tenant, the cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repair of the damage. In the event that Landlord does not deliver the Landlord Repair Notice within
sixty (60) days following the date the casualty becomes known to Landlord, Tenant shall, at its sole cost and expense, repair any injury or damage to the Tenant Improvements and the Original Improvements installed in the Premises and shall
return such Tenant Improvements and Original Improvements to their original condition. Whether or not Landlord delivers a Landlord Repair Notice, prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review
and approval, all plans, specifications and working drawings relating thereto, and Landlord shall select the contractors to perform such improvement work. Tenant shall in addition cooperate with requests for information regarding any repairs from
Landlord’s insurer(s) by providing the requested information within ten (10) days after Tenant receives the request. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s
business resulting in any way from such damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and the Premises are not occupied by
Tenant as a result thereof, then during the time and to the extent the Premises are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is unfit for occupancy for the
purposes permitted under this Lease bears to the total rentable square feet of the Premises. In the event that Landlord shall not deliver the Landlord Repair Notice, Tenant’s right to rent abatement pursuant to the preceding sentence shall
terminate as of the date which is reasonably determined by Landlord to be the date Tenant should have completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith. 

11.2 Landlord’s Option to Repair. Notwithstanding the terms of Section 11.1 of
this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after the date of discovery of the
damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall be damaged by fire or other casualty or cause, whether or not the Premises
are affected, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one hundred eighty (180) days after the date of discovery of the damage (when
such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project or ground lessor with respect to the Building or Project shall require that the insurance proceeds or any portion
thereof be used to retire the mortgage debt, or shall terminate the ground lease, as the case may be; (iii) the damage is not fully covered by Landlord’s insurance policies; (iv) the damage occurs during the last twelve
(12) months of the Lease Term; or (v) any owner of any other portion of the Project, other than Landlord, does not intend to repair the damage to such portion of the Project; provided, however, that if Landlord does not elect to terminate
this Lease pursuant to Landlord’s 

  
 23 

 
termination right as provided above, and the repairs cannot, in the reasonable opinion of Landlord, be completed within one hundred eighty (180) days after being commenced, Tenant may elect,
no earlier than sixty (60) days after the date of the damage and not later than ninety (90) days after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which
date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant. Notwithstanding the provisions of this Section 11.2, Tenant shall have the right to
terminate this Lease under this Section 11.2 only if each of the following conditions is satisfied: (a) the damage to the Project by fire or other casualty was not caused by the gross negligence or intentional act of
Tenant or its partners or subpartners and their respective officers, agents, servants, employees, and independent contractors; (b) as a result of the damage, Tenant cannot reasonably conduct business from the Premises; and, (c) as a result
of the damage to the Project, Tenant does not occupy or use the Premises at all. 
 11.3 Waiver of Statutory
Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building
or the Project, and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the
absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the
Project. 
 12. NONWAIVER No provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a
writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other term, covenant or condition herein
contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so
accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of Landlord’s right to receive the full
amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s
right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder, or after the giving of any
notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or after final judgment for possession
of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment. 

13. CONDEMNATION If the whole or any part of the Premises, Building or Project shall be taken by power of eminent domain or
condemned by any competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use,
reconstruction or remodeling of any part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease
effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled
to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures belonging to Tenant and removable by Tenant
upon expiration of the Lease Term pursuant to the terms of this Lease, for loss of goodwill, business and business interruption, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with
respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so
terminated, Landlord shall, to the extent of the condemnation proceeds received by Landlord, promptly restore the remaining Premises to the same condition they were in prior to such condemnation (to the extent practical), less the portion thereof
lost due to such condemnation, and the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Notwithstanding anything to the
contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the
Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the
entire award made in connection with any such temporary taking. 

  
 24 

 14. ASSIGNMENT AND SUBLETTING 

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge,
hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any
part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter
sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent
to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one
hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and
the consideration therefor, including calculation of the “Transfer Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee,
and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, business credit and
personal references and history of the proposed Transferee and any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature
of such Transferee’s business and proposed use of the Subject Space. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option,
constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees (including, without
limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, not to exceed $2,500.00 for a Transfer in the ordinary course of business, within thirty (30) days after written
request by Landlord. 
 14.2 Landlord’s Consent. Landlord shall not unreasonably withhold, condition or
delay its consent to any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be
reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply: 

14.2.1 The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the
Building or the Project; 
 14.2.2 The Transferee is either a governmental agency or instrumentality thereof; 

14.2.3 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities
to be undertaken in connection with the Transfer on the date consent is requested; or 
 14.2.4 The proposed Transfer would
cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease. 

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not
exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to
Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice such that Landlord would initially have been entitled to refuse its consent to such
Transfer under this Section 14.2, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under
Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under
Section 14.2 or otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant’s
business including, without limitation, loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought, and Tenant hereby waives all other remedies, including, without limitation, any right at law or equity to
terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws, on behalf of the proposed Transferee. 

14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree
is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant from such Transferee. “Transfer
Premium” shall mean all rent, 

  
 25 

 
additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of
the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, and after deduction of (i) any costs of improvements made to the Subject Space in connection with such Transfer, (ii) brokerage commissions
paid in connection with such Transfer, and (iii) reasonable legal fees incurred in connection with such Transfer. “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration
paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to
Transferee in connection with such Transfer. The determination of the amount of Landlord’s applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant under the Transfer. 

14.4 Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in this
Article 14, in the event Tenant contemplates a Transfer which, together with all prior Transfers then remaining in effect, would cause fifty percent (50%) or more of the Premises to be Transferred for more than twenty five percent (25%) of
the then remaining Lease Term (taking into account any extension of the Lease Term which has irrevocably exercised by Tenant), Tenant shall give Landlord notice (the “Intention to Transfer Notice”) of such contemplated Transfer
(whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant intends to
Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective Date”), and the contemplated length of the term of such contemplated
Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Section 14.4 in order to allow Landlord to elect to recapture the Contemplated Transfer Space. Thereafter,
Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease
with respect to such Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved herein shall be
prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon
request of either party, the parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this Section 14.4, then,
subject to the other terms of this Article 14, for a period of nine (9) months (the “Nine Month Period”) commencing on the last day of such thirty (30) day period, Landlord shall not have any right to recapture the
Contemplated Transfer Space with respect to any Transfer made during the Nine Month Period, provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer Notice, and provided further that any such Transfer
shall be subject to the remaining terms of this Article 14. If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated, then upon the expiration of the term of any Transfer of such Contemplated
Transfer Space consummated within such Nine Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this
Section 14.4. Notwithstanding anything herein to the contrary, if Landlord notifies Tenant of Landlord’s election to recapture the Contemplated Transfer Space and terminate this Lease, Tenant shall have five
(5) business days to withdraw its Intention to Transfer Notice of the contemplated Transfer. 
 14.5 Effect of
Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either
Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon
Landlord’s request a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from
such Transfer, and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease,
including, without limitation, in connection with the Subject Space. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have
the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than two percent (2%), Tenant shall
pay Landlord’s costs of such audit. 
 14.6 Additional Transfers. For purposes of this Lease, the term
“Transfer” shall also include (i) if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent (50%) or more
of partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof, and (ii) if Tenant is a closely held corporation 

  
 26 

 
(i.e., whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant or
(B) the sale or other transfer of an aggregate of fifty percent (50%) or more of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12)-month period, or (C) the sale, mortgage,
hypothecation or pledge of an aggregate of fifty percent (50%) or more of the value of the unencumbered assets of Tenant within a twelve (12)-month period. 

14.7 Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this
Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the Subject Space by any lawful means, or (ii) require that such Transferee
attorn to and recognize Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease, Landlord is hereby irrevocably authorized, as Tenant’s agent and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease)
until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee shall assume in writing all
obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of
any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any Transferee be deemed a waiver of
Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective unless the guarantor also
consents to such Transfer. 
 14.8 Non-Transfers. Notwithstanding
anything to the contrary contained in this Article 14, (A) an assignment or subletting of all or a portion of the Premises to an affiliate of Tenant (an entity which is controlled by, controls, or is under common control with, Tenant), (B) a
sale of corporate shares of capital stock in Tenant on a nationally-recognized stock exchange, (C) an assignment of the Lease to an entity which acquires all or substantially all of the stock or assets of Tenant, or (D) an assignment of
the Lease to an entity which is the resulting entity of a merger or consolidation of Tenant during the Lease Term (any such assignee or sublessee described in items (A) through (D) of this Section 14.8 hereinafter
referred to as a “Permitted Transferee”), shall not be deemed a Transfer under this Article 14, provided that (i) Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any
documents or information requested by Landlord regarding such assignment or sublease or such affiliate, (ii) such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, (iii) such Permitted
Transferee shall be of a character and reputation consistent with the quality of the Building, (iv) in connection with a Permitted Transferee pursuant to items (C) and (D), such Permitted Transferee shall have a tangible net worth (not
including goodwill as an asset) computed in accordance with generally accepted accounting principles (“Net Worth”) at least equal to the Net Worth of Tenant on the day immediately preceding the effective date of such assignment or
sublease, and (v) no assignment relating to this Lease, whether with or without Landlord’s consent, shall relieve Tenant from any liability under this Lease, and, in the event of an assignment of Tenant’s entire interest in this
Lease, the liability of Tenant and such transferee shall be joint and several. An assignee of Tenant’s entire interest in this Lease who qualifies as a Permitted Transferee may also be referred to herein as a “Permitted Transferee
Assignee.” “Control,” as used in this Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting
securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity. No such permitted assignment or
subletting shall serve to release Tenant from any of its obligations under this Lease. 
 15. SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE
FIXTURES 
 15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of
Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any
agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the
return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not
work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies. 

15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination
of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession 

  
 27 

 
of the Premises to Landlord in as good order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear and repairs which are
specifically made the responsibility of Landlord hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture,
equipment, freestanding cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant,
as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal. 

15.3 Environmental Assessment. In connection with its surrender of the Premises, Tenant shall submit to Landlord,
at least one hundred twenty (120) days prior to the expiration date of this Lease (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such termination), an environmental Assessment of the Premises
by a competent and experienced environmental engineer or engineering firm reasonably satisfactory to Landlord (pursuant to a contract approved by Landlord and providing that Landlord can rely on the Environmental Assessment), which
(i) evidences that the Premises are in a clean and safe condition and free and clear of any Hazardous Materials; and (ii) includes a review of the Premises by an environmental consultant for asbestos, mold, fungus, spores, and other
moisture conditions, on-site chemical use, and lead-based paint. If such Environmental Assessment reveals that remediation or Clean-up is required under any
Environmental Laws, Tenant shall submit a remediation plan prepared by a recognized environmental consultant and shall be responsible for all costs of remediation and Clean-up, as more particularly provided in
Section 5.3, above. 
 15.4 Condition of the Building and Premises Upon Surrender. In
addition to the above requirements of this Article 15, upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, surrender the Premises and Building such that the same are in compliance with all
Applicable Laws and with Tenant having complied with all of Tenant’s obligations under this Lease, including those relating to improvement, repair, maintenance, compliance with law, testing and other related obligations of Tenant set forth in
Article 7 of this Lease. In the event that the Building and Premises shall be surrendered in a condition which does not comply with the terms of this Section 15.4, because Tenant failed to comply with its obligations
set forth in Lease, then following thirty (30) days’ notice to Tenant, during which thirty (30) day period Tenant shall have the right to cure such noncompliance, Landlord shall be entitled to expend all reasonable costs in order to
cause the same to comply with the required condition upon surrender and Tenant shall immediately reimburse Landlord for all such costs within thirty (30) days following Tenant’s receipt of Landlord’s written demand therefor and Tenant
shall be deemed during the period that Tenant or Landlord, as the case may be, perform obligations relating to the Surrender Improvements to be in holdover under Article 16 of this Lease. 

16. HOLDING OVER. 
 If
Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the express or implied consent of Landlord, such tenancy shall be from
month-to-month only, and shall not constitute a renewal hereof or an extension for any further term. If Tenant holds over after the expiration of the Lease Term
of earlier termination thereof, without the express or implied consent of Landlord, such tenancy shall be deemed to be a tenancy by sufferance only, and shall not constitute a renewal hereof or an extension for any further term. In either case, Rent
shall be payable at a monthly rate equal to (i) one hundred fifty percent (150%) of the Rent applicable during the last rental period of the Lease Term under this Lease for the initial month of such holdover, and (ii) two hundred percent
(200%) thereafter. Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement
contained herein. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as
provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If
Tenant fails to surrender the Premises within thirty (30) days after the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord
harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to
surrender and any lost profits to Landlord resulting therefrom. 
 17. ESTOPPEL CERTIFICATES Within ten (10) business days
following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit D, attached hereto (or such
other form as may be required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested
by Landlord or Landlord’s mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any 

  
 28 

 
portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes. At any time during the Lease Term, but not more than one
(1) time per calendar year except in connection with a sale or financing of the Building, or in connection with Tenant’s request for Landlord’s approval to a Transfer or an Alteration, Landlord may require Tenant to provide Landlord
with a current financial statement and financial statements of the two (2) years prior to the current financial statement year. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the
normal practice of Tenant, shall be audited by an independent certified public accountant. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments following the expiration of the notice and cure
period set forth in Section 19.1.4, below, shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception. 

18. SUBORDINATION This Lease shall be subject and subordinate to all present and future ground or underlying leases of the
Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and
replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying
leases, require in writing that this Lease be superior thereto. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn,
without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do
so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this Lease and not
disturb Tenant’s occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord’s interest herein may be assigned as security
at any time to any lienholder. Tenant shall, within ten (10) business days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority
of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise
adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale. Concurrently with the execution of this Lease, Landlord shall have any mortgagee of the Property enter into its usual
nondisturbance agreement with Tenant. 
 19. DEFAULTS; REMEDIES 

19.1 Events of Default. The occurrence of any of the following shall constitute a default of this Lease by
Tenant: 
 19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part
thereof, when due unless such failure is cured within five (5) business days after notice; or 
 19.1.2 Except where a
specific time period is otherwise set forth for Tenant’s performance in this Lease, in which event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2, any
failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant;
provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter
diligently proceeds to rectify and cure such default; or 
 19.1.3 Abandonment of all or a substantial portion of the
Premises by Tenant; or 
 19.1.4 The failure by Tenant to observe or perform according to the provisions of Articles
5, 14, 17 or 18 of this Lease where such failure continues for more than two (2) business days after notice from Landlord. 

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law. 

19.2 Remedies Upon Default. Upon the occurrence of any event of default by Tenant, Landlord shall have, in
addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all of which shall be cumulative
and nonexclusive, without any notice or demand whatsoever. 
 19.2.1 Terminate this Lease, in which event Tenant shall
immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for 

  
 29 

 
possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without
being liable for prosecution or any claim for damages therefor; and Landlord may recover from Tenant the following: 

(i) The worth at the time of award of the unpaid rent which has been earned at the time of such termination;
plus 
 (ii) The worth at the time of award of the amount by which the unpaid rent which would have been
earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(iii) The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term
after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(iv) Any other amount necessary to compensate Landlord for all the detriment proximately caused by
Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, brokerage commissions and advertising expenses incurred,
expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and 

(v) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be
permitted from time to time by applicable law. 
 The term “rent” as used in this
Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(i) and
(ii), above, the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the maximum amount of such interest permitted by law. As used
in Section 19.2.1(iii) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one
percent (1%). 
 19.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may
continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this
Lease on account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due. 

19.2.3 Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and
in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any declaratory,
injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof. 

19.3 Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on account of any default by
Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in
Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions
or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder. 

19.4 Efforts to Relet. No re-entry or repossession, repairs, maintenance,
changes, alterations and additions, reletting, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or
Tenant’s right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by
Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or reinstate this Lease. 

19.5 Landlord Default.  

19.5.1 General. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall not be in
default in the performance of any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30) days after the receipt of notice from Tenant

  
 30 

 
specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its
performance, then Landlord shall not be in default under this Lease if it shall commence such performance within such thirty (30) day period and thereafter diligently pursue the same to completion. Upon any such default by Landlord under this
Lease, Tenant may, except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity. 

19.5.2 Abatement of Rent. In the event that Tenant is prevented from using, and does not use, the Premises or any
portion thereof, as a result of (i) any repair, maintenance or alteration performed by Landlord, or which Landlord failed to perform, after the Lease Commencement Date and required by this Lease, which substantially interferes with
Tenant’s use of the Premises, or (ii) any failure to provide services, utilities or access to the Premises as required by this Lease (either such set of circumstances as set forth in items (i) or (ii), above, to be known as an
“Abatement Event”), then Tenant shall give Landlord notice of such Abatement Event, and if such Abatement Event continues for five (5) consecutive business days after Landlord’s receipt of any such notice (the
“Eligibility Period”) and either (A) Landlord does not diligently commence and pursue to completion the remedy of such Abatement Event or (B) Landlord receives proceeds from its rental interruption insurance which covers
such Abatement Event, then the Base Rent and Tenant’s Share of Direct Expenses shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and
does not use for the normal conduct of Tenant’s business, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total
rentable area of the Premises; provided, however, in the event that Tenant is prevented from using, and does not use, a portion of the Premises for a period of time in excess of the Eligibility Period and the remaining portion of the Premises is not
sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not conduct its business from such remaining portion, then for such time after expiration of the Eligibility Period during which Tenant is so prevented from
effectively conducting its business therein, the Base Rent and Tenant’s Share of Direct Expenses for the entire Premises shall be abated for such time as Tenant continues to be so prevented from using, and does not use, the Premises. If,
however, Tenant reoccupies any portion of the Premises during such period, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of
the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises. To the extent an Abatement Event is caused by an event covered by Articles 11 or 13 of this Lease, then Tenant’s right to abate
rent shall be governed by the terms of such Article 11 or 13, as applicable, and the Eligibility Period shall not be applicable thereto. Such right to abate Base Rent and Tenant’s Share of Direct Expenses shall be Tenant’s
sole and exclusive remedy for rent abatement at law or in equity for an Abatement Event. Except as provided in this Section 19.5.2, nothing contained herein shall be interpreted to mean that Tenant is excused from paying
Rent due hereunder. 
 19.6 Consequential Damages. Notwithstanding anything contained in this Lease to the
contrary, neither party will be liable to the other for any business interruption, loss of profit or other punitive or consequential damages arising out of this Lease or any default hereunder, other than those consequential damages incurred by
Landlord in connection with a holdover of the Premises by Tenant after the expiration or earlier termination of this Lease, or in connection with Tenant’s use of Hazardous Materials. In addition, in no event shall Landlord be liable to Tenant
for any loss to inventory, scientific research, scientific experiments, laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and description kept at the Premises and any and all
income derived or derivable therefrom. 
 20. COVENANT OF QUIET ENJOYMENT Landlord covenants that Tenant, on paying the Rent,
charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall,
during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing
covenant is in lieu of any other covenant express or implied. 
 21. SECURITY DEPOSIT Concurrently with Tenant’s execution
of this Lease, Tenant shall deposit with Landlord a security deposit (the “Security Deposit”) in the amount set forth in Section 8 of the Summary, as security for the faithful performance by Tenant of all
of its obligations under this Lease. If Tenant defaults with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, the removal of property and the repair of resultant damage, Landlord
may, without notice to Tenant, but shall not be required to apply all or any part of the Security Deposit for the payment of any Rent or any other sum in default and Tenant shall, upon demand therefor, restore the Security Deposit to its original
amount. Any unapplied portion of the Security Deposit shall be returned to Tenant, or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder, within sixty (60) days following the expiration of the Lease Term.
Tenant shall not be entitled to any interest on the Security Deposit. Tenant hereby irrevocably waives and relinquishes any and all rights, benefits, or protections, if any, Tenant now has, or in the future may have, under

  
 31 

 
Section 1950.7 of the California Civil Code, any successor statute, and all other provisions of law, now or hereafter in effect, including, but not limited to, any provision of law which
(i) establishes the time frame by which a landlord must refund a security deposit under a lease, and/or (ii) provides that a landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment
of rent, to repair damage caused by a tenant or to clean the subject premises. Tenant acknowledges and agrees that (a) any statutory time frames for the return of a security deposit are superseded by the express period identified in this
Article 21, above, and (b) rather than be so limited, Landlord may claim from the Security Deposit (1) any and all sums expressly identified in this Article 21, above, and (2) any additional sums reasonably necessary to
compensate Landlord for any and all losses or damages caused by Tenant’s default of this Lease, including, but not limited to, all damages or rent due upon termination of Lease pursuant to Section 1951.2 of the California Civil Code. 

22. COMMUNICATIONS AND COMPUTER LINE Tenant may install, maintain, replace, remove or use any communications or computer wires
and cables serving the Premises (collectively, the “Lines”), provided that Tenant shall obtain Landlord’s prior written consent, use an experienced and qualified contractor approved in writing by Landlord, and comply with all
of the other provisions of Articles 7 and 8 of this Lease. Tenant shall pay all costs in connection therewith. Landlord reserves the right, upon notice to Tenant prior to the expiration or earlier termination of this Lease, to require that
Tenant, at Tenant’s sole cost and expense, remove any Lines located in or serving the Premises prior to the expiration or earlier termination of this Lease. 

23. SIGNS 
 23.1
Signage. Subject to Landlord’s prior written approval, which shall not be unreasonably withheld, conditioned or delayed, and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant,
at its sole cost and expense, may install (i) non-exclusive identification signage on the Building monument sign, and (ii) illuminated Building top signage on the West facing portion of the Building
directly above the existing monument sign (collectively, “Tenant’s Signage”); provided, however, in no event shall Tenant’s Signage include an “Objectionable Name,” as that term is defined in
Section 23.3, of this Lease. All such signage shall be subject to Landlord signage criteria for the Building and to Tenant’s obtaining all required governmental approvals. All permitted signs shall be maintained by
Tenant at its expense in a first-class and safe condition and appearance. Upon the expiration or earlier termination of this Lease, Tenant shall remove all of its signs at Tenant’s sole cost and expense. The graphics, materials, color, design,
lettering, lighting, size, illumination, specifications and exact location of Tenant’s Signage (collectively, the “Sign Specifications”) shall be subject to the prior written approval of Landlord, which approval shall not be
unreasonably withheld, conditioned or delayed (provided that the exact location of Tenant’s Signage on the Building monument sign shall be determined by Landlord in its sole discretion), and shall be consistent and compatible with the quality
and nature of the Project. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of Tenant’s Signage, Landlord has made no representation or warranty to Tenant with respect to the probability of obtaining all necessary
governmental approvals and permits for Tenant’s Signage. In the event Tenant does not receive the necessary governmental approvals and permits for Tenant’s Signage, Tenant’s and Landlord’s rights and obligations under the
remaining terms and conditions of this Lease shall be unaffected. 
 23.2 Objectionable Name. Tenant’s
Signage shall not include a name or logo which relates to an entity which is of a character or reputation, or is associated with a political faction or orientation, which is inconsistent with the quality of the Project, or which would otherwise
reasonably offend a landlord of the Comparable Buildings (an “Objectionable Name”). The parties hereby agree that the following name, or any reasonable derivation thereof, shall be deemed not to constitute an Objectionable Name:
“InhibRx, LP.” 
 23.3 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names
or advertisements which are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Any signs, window coverings, or blinds (even if the same are located behind the
Landlord-approved window coverings for the Building), or other items visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole discretion. 

23.4 Termination of Right to Tenant’s Signage. The rights contained in this Article 23 shall be
personal to Original Tenant and its Permitted Assignee, and may only be exercised and maintained by such parties (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) to the extent
(x) they are not in default under this Lease (beyond any applicable notice and cure period) and (y) if they occupy the entire Premises. 

23.5 Lobby Directory and Suite Signage. Landlord, at its initial cost and expense, shall install
(i) Building standard suite entry signage, and (ii) an entry in the Building directory located in the lobby. Any changes to Tenant’s suite entry signage, or lobby directory signage shall be subject to Landlord’s prior written
approval and shall be performed at Tenant’s sole cost and expense. 

  
 32 

 24. COMPLIANCE WITH LAW Tenant shall not do anything or suffer anything to be
done in or about the Premises or the Project which will in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated. At its sole cost and
expense, Tenant shall promptly comply with all such governmental measures. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local governmental body charged with the establishment, regulation
and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply promptly with such standards or regulations. Tenant shall be responsible, at its
sole cost and expense, to make all alterations to the Building and Premises as are required to comply with the governmental rules, regulations, requirements or standards described in this Article 24. The judgment of any court of competent
jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant. 

25. LATE CHARGES If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s
designee within five (5) business days after Tenant’s receipt of written notice from Landlord that said amount is due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any reasonable
attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of
Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing
hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the
Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus four
(4) percentage points, and (ii) the highest rate permitted by applicable law. 
 26. LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

 26.1 Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant under this
Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such
failure shall continue in excess of the time allowed under Section 19.1.2, above, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or
perform any such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder. 

26.2 Tenant’s Reimbursement. Except as may be specifically provided to the contrary in this Lease, Tenant
shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant’s defaults
pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10 of this Lease; and (iii) sums equal to all expenditures made and
obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all reasonable legal fees and other
amounts so expended. Tenant’s obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term. 

27. ENTRY BY LANDLORD Landlord reserves the right at all reasonable times and upon at least 24 hours’ prior notice to Tenant
(except in the case of an emergency) to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or insurers or, during the last ten
(10) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility (to the extent applicable pursuant to then applicable law); or (iv) alter, improve or repair the Premises or the Building, or for
structural alterations, repairs or improvements to the Building or the Building’s systems and equipment. Landlord may make any such entries without the abatement of Rent, except as otherwise provided in this Lease, and may take such reasonable
steps as required to accomplish the stated purposes. In an emergency, Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner
hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. In exercising the entry rights set forth in this
Section, Landlord shall use commercially reasonable efforts to minimize interference with the conduct of Tenant’s business in connection with such entries into the Premises. 

  
 33 

 28. TENANT PARKING Tenant, at no charge throughout the Term of this Lease
(other than Direct Expenses to the extent allowed by the terms of Article 4 of this Lease), shall have the right to use the amount of parking set forth in Section 9 of the Summary, in the on-site and/or off-site, as the case may be, parking facility (or facilities) which serve the Project. Tenant shall abide by all reasonable rules and regulations which are
prescribed from time to time and of which Tenant is given notice for the orderly operation and use of the parking facility where the parking passes are located (including any sticker or other identification system established by Landlord and the
prohibition of vehicle repair and maintenance activities in the parking facilities), and shall cooperate in seeing that Tenant’s employees and visitors also comply with such rules and regulations. During the initial Lease Term and, if
applicable, the Option Term, such parking spaces shall be provided at no additional charge to Tenant (other than Operating Expenses to the extent allowed by the terms of Section 4.2.4 of this Lease); provided that Tenant
shall also be responsible for the full amount of any taxes imposed by any governmental authority in connection with the renting of such parking passes by Tenant or the use of the parking facility by Tenant. Tenant shall have the exclusive use of the
EV Charging Station and Tenant shall pay to Landlord as Additional Rent the cost incurred by Landlord to operate and maintain the EV Charging Station. Tenant’s use of the Project parking facility shall be at Tenant’s sole risk and Tenant
acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal injury or property damage or theft relating to or connected with the parking rights
granted herein or any of Tenant’s, its employees’ and/or visitors’ use of the parking facilities. 
 29. MISCELLANEOUS PROVISIONS 

29.1 Terms; Captions. The words “Landlord” and “Tenant” as used herein shall
include the plural as well as the singular. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be assumed as
though in each case fully expressed. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections. 

29.2 Binding Effect. Subject to all other provisions of this Lease, each of the covenants, conditions and
provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective heirs, personal representatives, successors or assigns, provided this clause
shall not permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease. 
 29.3 No Air
Rights. No rights to any view or to light or air over any property, whether belonging to Landlord or any other person, are granted to Tenant by this Lease. If at any time any windows of the Premises are temporarily darkened or the light or
view therefrom is obstructed by reason of any repairs, improvements, maintenance or cleaning in or about the Project, the same shall be without liability to Landlord and without any reduction or diminution of Tenant’s obligations under this
Lease. 
 29.4 Modification of Lease. Should any current or prospective mortgagee or ground lessor for the
Building or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, then and in such
event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) business days following a request therefor. At the request of
Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) business days following the request therefor. 

29.5 Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right to transfer all or any
portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease and Tenant agrees to look solely to such
transferee for the performance of Landlord’s obligations hereunder after the date of transfer and such transferee shall be deemed to have fully assumed and be liable for all obligations of this Lease to be performed by Landlord, including the
return of any Security Deposit, and Tenant shall attorn to such transferee. 
 29.6 Prohibition Against
Recording. Except as provided in Section 29.4 of this Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through, under or
on behalf of Tenant. 
 29.7 Landlord’s Title. Landlord’s title is and always shall be paramount to
the title of Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord. 

29.8 Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties hereto
or by any third party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant. 

  
 34 

 29.9 Application of Payments. Landlord shall have the right to
apply payments received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments, to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole discretion, may elect. 

29.10 Time of Essence. Time is of the essence with respect to the performance of every provision of this Lease in
which time of performance is a factor. 
 29.11 Partial Invalidity. If any term, provision or condition
contained in this Lease shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid or
unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by law. 

29.12 No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations,
including, but not limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same
level or on the same basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto. 

29.13 Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default by
Landlord under this Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively to
an amount which is equal to the lesser of (a) the interest of Landlord in the Building or (b) the equity interest Landlord would have in the Building if the Building were encumbered by third-party debt in an amount equal to eighty percent
(80%) of the value of the Building (as such value is determined by Landlord), provided that in no event shall such liability extend to any sales or insurance proceeds received by Landlord or the Landlord Parties in connection with the Project,
Building or Premises. Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or
under Tenant. The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers, directors,
trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord
or any partner of Landlord is a trust), have any liability for the performance of Landlord’s obligations under this Lease. 

29.14 Entire Agreement. It is understood and acknowledged that there are no oral agreements between the parties
hereto affecting this Lease and this Lease constitutes the parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and
understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms, covenants, conditions or
provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto. 
 29.15
Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building or Project.

to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease (collectively, a “Force Majeure”), notwithstanding anything to the contrary contained in
this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be
extended by the period of any delay in such party’s performance caused by a Force Majeure. 
 29.17 Waiver of
Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of

TENANT WORK LETTER 

This Tenant Work Letter shall set forth the terms and conditions relating to the construction of the tenant improvements in
the Premises. This Tenant Work Letter is essentially organized chronologically and addresses the issues of the construction of the Premises, in sequence, as such issues will arise during the actual construction of the Premises. All references in
this Tenant Work Letter to Articles or Sections of “this Lease” shall mean the relevant portion of Articles 1 through 29 of the Lease to which this Tenant Work Letter is attached as Exhibit B and of which this
Tenant Work Letter forms a part, and all references in this Tenant Work Letter to Sections of “this Tenant Work Letter” shall mean the relevant portion of Sections 1 through 6 of this Tenant Work Letter. 

SECTION 1 

TENANT IMPROVEMENTS 

Landlord and Tenant have approved that certain space plan which is attached hereto as Schedule 1 (the “Space
Plan”). Within five (5) days of the date on which Tenant executes this Lease, Tenant shall cooperate in good faith with Landlord’s architects and engineers to supply such information necessary to allow the Landlord’s
architects and engineers to complete the architectural and engineering drawings for the Premises, and the final architectural working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable
permits and in a manner consistent with, and which are a natural and logical extension of, the Space Plan (collectively, the “Approved Working Drawings”). Landlord shall construct the improvements in the Premises (the
“Tenant Improvements”) in good workmanlike condition pursuant to the Approved Working Drawings. In addition, Landlord shall, at Landlord sole cost and expense, prior to the Lease Commencement Date, upgrade or modernize the building
directory (collectively, the “Landlord Work”). Tenant shall make no changes or modifications to (a) the Space Plan, (b) once completed, the Approved Working Drawings, or (c) the Landlord Work, without the prior
written consent of Landlord, which consent may be withheld in Landlord’s sole discretion if such change or modification is reasonably likely to directly or indirectly materially delay the “Substantial Completion,” as that term is
defined in Section 5.1 of this Tenant Work Letter, of the Premises or increase the cost of designing or constructing the Tenant Improvements. The Tenant Improvements and the Landlord Work shall be constructed in accordance
with Landlord’s Building standards, using Building standard methods, materials and finishes. Notwithstanding the foregoing, except as specifically set forth in Section 2, below, the Tenant Improvements shall not
include built-in furniture, equipment, cubicle systems (including the cabling and phone wiring), personal property and/or any above-standard electrical, mechanical or plumbing systems. 

SECTION 2 

CHANGE ORDER; CHANGE ORDER ALLOWANCE

substitutions shall be made to (i) the Space Plan, (ii) the Approved Working Drawings (once the same are completed), or (iii) the Tenant Improvements (collectively, “Change Orders”), then any additional costs which
arise in connection with Change Orders shall be paid by Tenant to Landlord within five (5) business days following Landlord’s written request therefor, which request shall be accompanied by reasonable
back-up documentation regarding the calculation of such additional costs; provided that Landlord may initially reasonably estimate the additional costs which arise in connection with Change Orders and Tenant
shall pay to Landlord such estimated amount and, following completion of the Tenant Improvements, Landlord and Tenant shall reconcile the amount paid by Tenant with the amount that should have been paid by Tenant based on the actual costs incurred
by Landlord. 
 2.2 Change Order Allowance. Subject to the terms and conditions set forth in this
Section 2.2, Tenant shall be entitled to a one-time allowance in an amount not to exceed Six Hundred Eighty-Four Thousand Two Hundred Twenty and 00/100 Dollars ($684,220.00) (i.e.,
$20.00 per rentable square foot of the Premises) (the “Change Order Allowance”) to be used solely for hard and soft costs in connection with any Change Orders (provided that in no event shall more than One Hundred Seventy-One Thousand Fifty-Five and 00/100 Dollars

($171,055.00) (i.e., $5.00 per rentable square foot of the Premises) of the Change Order Allowance be used for soft costs in connection with Change Orders), pursuant to a written notice delivered
to Landlord on or before the Lease Commencement Date. In the event Tenant timely exercises its right to use all or any portion of the Change Order Allowance, the monthly Base Rent for the Premises shall be increased by an amount equal to the
“Additional Monthly Base Rent,” as that term is defined below, in order to repay the Change Order Allowance to Landlord. The “Additional Monthly Base Rent” shall be determined as the missing component of an annuity, which
annuity shall have (i) the amount of the Change Order Allowance which Tenant elects to utilize as the present value amount, (ii) eighty-four (84) as the number of payments, (ii) two-thirds
(2/3) of a percent, which is equal to eight percent (8%) divided by twelve (12) months per year, as the monthly interest factor, and (z) the Additional Monthly Base Rent as the missing component of the annuity. If Tenant elects to utilize
all or a portion of the Change Order Allowance, then the parties shall promptly execute an amendment to this Lease setting forth the new amount of the Base Rent and the Change Order Allowance computed in accordance with this
Section 2.2.

NET EQUIVALENT LEASE RATE 

In order to analyze the net effective rentable obligations based on the factors to be considered in calculating the Economic
Terms in connection with calculations under Section 1.4 of this Lease, and given that the Economic Terms may vary in terms of length or term, rental rate, concessions, etc., the following steps shall be taken into consideration to
“adjust” the objective data from each of Economic Terms. By taking this approach, a “Net Equivalent Lease Rate” for each of the Economic Terms shall be determined using the following steps to adjust the Economic Terms, which will
allow for an “apples to apples” comparison of the Economic Terms. 
 1 The contractual rent payments for each of
the Economic Terms should be arrayed monthly or annually over the lease term of the First Offer Space. All Economic Terms should be adjusted to simulate a net rent structure, wherein the tenant is responsible for the payment of all property
operating expenses and taxes in a manner consistent with this Lease. This results in the estimate of Net Equivalent Rent received by each landlord for each Economic Terms being expressed as a periodic net rent payment. 

2 Any free rent or similar inducements received over time should be deducted in the time period in which they occur, resulting
in the net cash flow arrayed over the lease term. 
 3 The resultant net cash flow from the lease of the First Offer Space
should be then discounted (using an annual discount rate equal to 8.0%) to the First Offer Commencement Date, resulting in a net present value estimate. 

4 From the net present value, up front inducements (improvements allowances and other concessions) should be deducted. These
items should be deducted directly, on a “dollar for dollar” basis, without discounting since they are typically incurred at lease commencement, while rent (which is discounted) is a future receipt. 

5 The net present value should then amortized back over the lease term of the First Offer Space as a level monthly or annual
net rent payment using the same annual discount rate of 8.0% used in the present value analysis. This calculation will result in a hypothetical level or even payment over the option period, termed the “Net Equivalent Lease Rate” (or
constant equivalent in general financial terms).

 Exhibit 10.25 

FIRST AMENDMENT TO LEASE 

This FIRST AMENDMENT TO LEASE (“First Amendment”) is made and entered into as of May 21, 2019, by and
between HCP TPSP, LLC, a Delaware limited liability company (“Landlord”), and INHIBRX, INC., a Delaware corporation (“Tenant”). 

R E C I T A L S : 

A.    Landlord and Tenant (as
successor-in-interest to InhibRx, LP, a Delaware limited partnership) are parties to that certain Lease dated September 8, 2017 (the “Lease”),
whereby Landlord leases to Tenant, and Tenant leases from Landlord, approximately 34,211 rentable square feet of space (the “Existing Premises”) consisting of the entire second
(2nd) floor of that certain building located at 11025 North Torrey Pines Road, San Diego, California (the “Building”). 

B.    Tenant desires to expand the Existing Premises to include that certain space consisting of
approximately 8,412 rentable square feet of space commonly known as Suite 140 and located on the first (1st) floor of the Building (the “Expansion Premises”), as delineated on
Exhibit A attached hereto and made a part hereof, and to make other modifications to the Lease, and in connection therewith, Landlord and Tenant desire to amend the Lease as hereinafter provided. 

A G R E E M E N T : 

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

1.    Capitalized Terms. All capitalized terms when used herein shall have the same meaning
as is given such terms in the Lease unless expressly superseded by the terms of this First Amendment. 

2.    Modification of Premises. Effective as of the date (the “Expansion
Commencement Date”) which is the earlier to occur of (i) the date upon which Tenant first commences to conduct business in the Expansion Premises, and (ii) the date upon which the Expansion Premises are “Ready for
Occupancy,” as that term is defined in Section 5.1 of the Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), which Expansion Commencement Date is anticipated to
be January 1, 2020, Tenant shall lease from Landlord and Landlord shall lease to Tenant the Expansion Premises. Consequently, effective upon the Expansion Commencement Date, the Existing Premises shall be increased to include the Expansion
Premises. Landlord and Tenant hereby acknowledge that such addition of the Expansion Premises to the Existing Premises shall, effective as of the Expansion Commencement Date, increase the size of the Premises to approximately 42,623 rentable square
feet. The Existing Premises and the Expansion Premises may hereinafter collectively be referred to as the “Premises.” 

 3.    Expansion Term. The term of
Tenant’s lease of the Expansion Premises (the “Expansion Term”) shall commence on the Expansion Commencement Date and shall expire coterminously with Tenant’s Lease of the Existing Premises on the Lease Expiration Date
(i.e., June 30, 2025), unless sooner terminated as provided in the Lease, as hereby amended. 

4.    Base Rent. 

4.1.    Existing Premises. Notwithstanding anything to the contrary in the Lease, as hereby
amended, Tenant shall continue to pay Base Rent for the Existing Premises in accordance with the terms of the Lease. 

4.2.    Expansion Premises. Commencing on the Expansion Commencement Date and continuing
throughout the Expansion Term, Tenant shall pay to Landlord monthly installments of Base Rent for the Expansion Premises as follows: 
  

							
	 Expansion Lease Year*
	  	Annual Base Rent	  	Monthly Installment
of Base Rent	  	Monthly Rental Rate per
Rentable Square Foot**
	 1
	  	$388,634.40	  	$32,386.20	  	$3.85
	 2
	  	$396,407.04	  	$33,033.92	  	$3.93
	 3
	  	$404,335.20	  	$33,694.60	  	$4.01
	 4
	  	$412,421.88	  	$34,368.49	  	$4.09
	 5
	  	$420,670.32	  	$35,055.86	  	$4.17
	 6
	  	$429,083.76	  	$35,756.98	  	$4.25

  

	*	 For purposes of this First Amendment, the term “Expansion Lease Year” shall mean each
consecutive twelve (12) month period during the Expansion Term; provided, however, that the first (1st) Expansion Lease Year shall commence on the Expansion Commencement Date and end on the
last day of the month in which the first anniversary of the Expansion Commencement Date occurs (or if the Expansion Commencement Date is the first (1st) day of a calendar month, then the first (1st) Expansion Lease Year shall commence on the Expansion Commencement Date and end on the day immediately preceding the first (1st) anniversary of
the Expansion Commencement Date), and further provided that the last Expansion Lease Year shall end on the Expansion Expiration Date. 

	**	 The calculation of the Monthly Base Rent per Rentable Square Foot reflects an annual increase of 2%, rounded
to the nearest cent, after the previous Expansion Lease Year. 

 Concurrently with Tenant’s execution
of this First Amendment, Tenant shall pay to Landlord the Base Rent and Tenant’s Share of Direct Expenses payable for the Expansion Premises for the first full month of the Expansion Term (i.e., Forty-Four Thousand Eight Hundred Seventy-Three
and 00/100 Dollars ($44,873.00)). 

  
 -2- 

 5.    Tenant’s Share of Direct
Expenses. 
 5.1.    Existing Premises. Notwithstanding anything to the contrary
in the Lease as hereby amended, Tenant shall continue to pay Tenant’s Share of Direct Expenses in connection with the Existing Premises in accordance with the terms of the Lease. 

5.2.    Expansion Premises. Except as specifically set forth in this
Section 5.2, commencing on the Expansion Commencement Date, Tenant shall pay Tenant’s Share of Direct Expenses in connection with the Expansion Premises in accordance with the terms of the Lease, provided that with
respect to the calculation of Tenant’s Share of Direct Expenses in connection with the Expansion Premises, Tenant’s Share of Direct Expenses shall be equal to 12.6397%. 

6.    Improvements. Except as specifically set forth herein or in the Tenant Work Letter
attached hereto as Exhibit B and incorporated herein, Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Expansion Premises, and Tenant shall accept the Expansion
Premises in its presently existing, “as-is” condition, and neither Landlord nor any agent of Landlord has made any representation or warranty to Tenant regarding the condition of the Expansion
Premises, the Building or the Project, or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business. In addition, Tenant hereby acknowledges that Tenant is currently in possession of the Existing Premises, and
that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Existing Premises, or with respect to the suitability of the foregoing for the conduct of Tenant’s business. Accordingly,
Tenant shall continue to accept the Existing Premises in its “as is” condition as of the date of this First Amendment. 

7.    Option to Extend Lease Term. Landlord and Tenant hereby acknowledge and agree that
Tenant’s right to extend the Lease Term pursuant to Section 2.2 of the Lease shall be applicable to the entire Premises (i.e., the Existing Premises and the Expansion Premises); provided, however, notwithstanding
anything in the Lease to the contrary, Tenant shall have the right to extend the Lease Term pursuant to Section 2.2 of the Lease with respect to the Existing Premises only or with respect to the entire Premises (i.e., the
Existing Premises and the Expansion Premises), and in no event shall Tenant have the right to extend the Lease Term for the Expansion Premises only. 

8.    Tenant’s Access. Subject to applicable laws and the other provisions of the
Lease, as hereby amended, and except in the event of an emergency, Tenant shall have access to the Building, the Premises and the Common Areas, other than common areas requiring access with a Building engineer, twenty-four (24) hours per day,
seven (7) days per week, every day of the year; provided, however, that Tenant shall only be permitted to have access to and use of the loading dock, mailroom and other limited-access areas of the Building during the normal operating hours of
such portions of the Building. 
 9.    Parking. Effective as of the Expansion
Commencement Date and continuing throughout the Expansion Term, Tenant, at no charge throughout the Expansion Term (other than 

  
 -3- 

 
Direct Expenses to the extent allowed by the terms of Article 4 of the Lease), shall have the right to use up to twenty-five (25) unreserved parking passes (i.e., three
(3) unreserved parking passes per 1,000 rentable square feet of the Expansion Premises) in connection with Tenant’s lease of the Expansion Premises, subject to and in accordance with the terms of the Lease. 

10.    Security Deposit. Notwithstanding anything in the Lease to the contrary, the Security
Deposit held by Landlord pursuant to the Lease, as amended hereby, shall equal Two Hundred Forty-Four Thousand Five Hundred Fifty-Three and 10/100 Dollars ($244,553.10). Landlord and Tenant acknowledge that, in accordance with Article 21 of
the Lease, Tenant has previously delivered the sum of One Hundred Ninety-Four Thousand Six Hundred Sixty-Eight and 10/100 Dollars ($194,668.10) (the “Existing Security Deposit”) to Landlord as security for the faithful performance
by Tenant of the terms, covenants and conditions of the Lease. Concurrently with Tenant’s execution of this First Amendment, Tenant shall deposit with Landlord an amount equal to Forty-Nine Thousand Eight Hundred Eighty-Five and 00/100 Dollars
($49,885.00) to be held by Landlord as a part of the Security Deposit. To the extent that the total amount held by Landlord at any time as security for the Lease, as hereby amended, is less than Two Hundred Forty-Four Thousand Five Hundred
Fifty-Three and 10/100 Dollars ($244,553.10), Tenant shall pay the difference to Landlord within ten (10) days following Tenant’s receipt of notice thereof from Landlord. 

11.    Statutory Disclosure and Related Terms. For purposes of Section 1938(a) of the
California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Premises have not undergone inspection by a Certified Access Specialist (CASp). As required by Section 1938(e) of the California Civil Code,
Landlord hereby states as follows: “A Certified Access Specialist (CASp) can inspect the subject Expansion Premises and determine whether the subject Expansion 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 Expansion Premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject
Expansion Premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee
for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the Expansion Premises.” In furtherance of the foregoing, Landlord and Tenant hereby agree as
follows: (a) any CASp inspection requested by Tenant shall be conducted, at Tenant’s sole cost and expense, by a CASp approved in advance by Landlord, while any CASp inspection initiated by Landlord shall be conducted, at Landlord’s
sole cost and expense, by a CASp designated by Landlord; (b) with respect to improvements or repairs required to correct violations discovered during a CASp inspection initiated by Tenant, pursuant to Article 24 of the
Lease, Tenant, at its sole cost and expense, shall be responsible for making any improvements or repairs within the Premises to correct violations of construction-related accessibility standards; and (c) if anything done by or for Tenant in its
use or occupancy of the Premis.es shall require any improvements or repairs to the Building or Project (outside the Premises) to correct violations of construction-related accessibility standards, then Tenant shall, at Landlord’s option, either
perform such repairs at Tenant’s sole cost and expense or reimburse Landlord upon demand, as Additional Rent, for the cost to Landlord of performing such repairs, provided that Landlord shall be solely responsible for the costs of performing
such improvements or repairs to correct such violations of construction-related 

  
 -4- 

 
accessibility standards if such violations were discovered during a CASp inspection initiated by Landlord. The terms of this Section 11 do not amend or reduce the
obligations of Landlord and Tenant set forth in Article 24 of the Lease regarding compliance with Applicable Laws, but apply solely to the obligations of Landlord and Tenant in connection with Tenant’s election to conduct a CASp
inspection hereunder. 
 12.    Broker. Landlord and Tenant hereby warrant to each other
that they have had no dealings with any real estate broker or agent in connection with the negotiation of this First Amendment other than CBRE, Inc. (the “Broker”), and that they know of no other real estate broker or agent who is
entitled to a commission in connection with this First Amendment. Each party agrees to indemnify and defend the other party against and hold the other party harmless from and against any and all claims, demands, losses, liabilities, lawsuits,
judgments, and costs and expenses (including, without limitation, reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party’s dealings with any

TENANT WORK LETTER 

This Tenant Work Letter shall set forth the terms and conditions relating to the construction of the tenant improvements in
the Expansion Premises. This Tenant Work Letter is essentially organized chronologically and addresses the issues of the construction of the Expansion Premises, in sequence, as such issues will arise during the actual construction of the Expansion
Premises. All references in this Tenant Work Letter to Sections of “this Tenant Work Letter” shall mean the relevant portion of Sections 1 through 6 of this Tenant Work Letter. 

SECTION 1 

TENANT IMPROVEMENTS 

Landlord and Tenant have approved that certain space plan which is attached hereto as Schedule 1 (the “Space
Plan”). Within five (5) days of the date on which Tenant executes this First Amendment, Tenant shall cooperate in good faith with Landlord’s architects and engineers to supply such information necessary to allow the
Landlord’s architects and engineers to complete the architectural and engineering drawings for the Expansion Premises, and the final architectural working drawings in a form which is complete to allow subcontractors to bid on the work and to
obtain all applicable permits and in a manner consistent with, and which are a natural and logical extension of, the Space Plan (collectively, the “Approved Working Drawings”). Landlord shall construct the improvements in the
Expansion Premises (the “Tenant Improvements”) in good workmanlike condition pursuant to the Approved Working Drawings. Tenant shall make no changes or modifications to (a) the Space Plan, or (b) once completed, the
Approved Working Drawings, without the prior written consent of Landlord, which consent may be withheld in Landlord’s sole discretion if such change or modification is reasonably likely to directly or indirectly materially delay the
“Substantial Completion,” as that term is defined in Section 5.1 of this Tenant Work Letter, of the Tenant Improvements or increase the cost of designing or constructing the Tenant Improvements. The Tenant
Improvements shall be constructed in accordance with Landlord’s Building standards, using Building standard methods, materials and finishes. Notwithstanding the foregoing, except as specifically set forth in Section 2,
below, the Tenant Improvements shall not include built-in furniture, equipment, cubicle systems (including the cabling and phone wiring), personal property and/or any above-standard electrical, mechanical or
plumbing systems. 
 SECTION 2 

CHANGE ORDERS 

In the event that after Tenant’s execution of this First Amendment, any revisions, changes, or substitutions shall be
made to (i) the Space Plan, (ii) the Approved Working Drawings (once the same are completed), or (iii) the Tenant Improvements (collectively, “Change Orders”), then any additional costs which arise in connection with
Change Orders shall be paid by Tenant to 

  
 EXHIBIT B 

  
 -1- 

 Landlord within five (5) business days following Landlord’s written request
therefor, which request shall be accompanied by reasonable back-up documentation regarding the calculation of such additional costs; provided that Landlord may initially reasonably estimate the additional
costs which arise in connection with Change Orders and Tenant shall pay to Landlord such estimated amount and, following completion of the Tenant Improvements, Landlord and Tenant shall reconcile the amount paid by Tenant with the amount that should
have been paid by Tenant based on the actual costs incurred by Landlord. 
 SECTION 3 

CONTRACTOR’S WARRANTIES AND GUARANTIES 

Landlord hereby assigns to Tenant all warranties and guaranties by the contractor who constructs the Tenant Improvements (the
“Contractor”) relating to the Tenant Improvements, and Tenant hereby waives all claims against Landlord relating to, or arising out of the construction of, the Tenant Improvements. 

SECTION 4 

INTENTIONALLY OMITTED 

SECTION 5 

COMPLETION OF THE TENANT IMPROVEMENTS; 

EXPANSION COMMENCEMENT DATE 

5.1    Ready for Occupancy. The Expansion Premises shall be deemed “Ready for
Occupancy” upon the Substantial Completion of the Tenant Improvements. For purposes of this First Amendment, “Substantial Completion” of the Tenant Improvements shall occur upon the completion of construction of the Tenant
Improvements in the Expansion Premises, with the exception of any punch list items and any tenant fixtures, work-stations, built-in furniture, or equipment to be installed by Tenant or under the supervision of
Contractor, and the receipt of a temporary certificate of occupancy, or it legal equivalent, for the Expansion Premises. 

5.2    Delay of the Substantial Completion of the Expansion Premises. Except as provided in
this Section 5.2, the Expansion Commencement Date shall occur as set forth in this First Amendment and Section 5.1, above. If there shall be a delay or there are delays in the Substantial
Completion of the Tenant Improvements or in the occurrence of any of the other conditions precedent to the Expansion Commencement Date, as set forth in of this First Amendment, as a result of (each, a “Tenant Delay”): 

5.2.1    Tenant’s failure to timely approve any matter requiring Tenant’s approval; 

5.2.2    A breach by Tenant of the terms of this Tenant Work Letter or the Lease, as hereby amended; 

5.2.3    Tenant’s request for changes to the Tenant Improvements, the Space Plan, or, once completed,
the Approved Working Drawings, or Tenant’s request for changes which cause the Approved Working Drawings to not be a logical extension of or consistent with the Space Plan or Tenant’s request for changes which require non-Building standard methods, materials or finishes; 

  
 EXHIBIT B 

  
 -2- 

 5.2.4    Tenant’s requirement for materials,
components, finishes or improvements which are not available in a commercially reasonable time given the anticipated date of Substantial Completion of the Tenant Improvements, as set forth in this First Amendment, or which are different from, or not
included in, Landlord’s standard improvement package items for the Building; 
 5.2.5    Changes to
the base, shell and core work of the Building required by the Approved Working Drawings; or 

5.2.6    Any other acts or omissions of Tenant, or its agents, or employees; 

then, notwithstanding anything to the contrary set forth in the Lease, as hereby amended, or this Tenant Work Letter and regardless of the
actual date of the Substantial Completion of the Tenant Improvements, the date of Substantial Completion of the Tenant Improvements shall be deemed to be the date the Substantial Completion of the Tenant Improvements would have occurred if no Tenant
delay or delays, as set forth above, had occurred. 
 SECTION 6 

MISCELLANEOUS 

6.1    Tenant’s Entry Into the Expansion Premises Prior to Substantial Completion.
Provided that Tenant and its agents do not interfere with Landlord’s work in the Building and the Expansion Premises, Landlord shall allow Tenant access to the Expansion Premises at least thirty (30) days prior to the Substantial
Completion of the Tenant Improvements for the purpose of Tenant installing Tenant’s furniture, equipment and/or fixtures (including Tenant’s data and telephone equipment) in the Expansion Premises. Prior to Tenant’s entry into the
Expansion Premises as permitted by the terms of this Section 6.1, Tenant shall submit a schedule to Landlord and Contractor, for their reasonable approval, which schedule shall detail the timing and purpose of Tenant’s
entry. Tenant shall hold Landlord harmless from and indemnify, protect and defend Landlord against any loss or damage to the Building or Premises and against injury to any persons caused by Tenant’s actions pursuant to this
Section 6.1. 
 6.2    Freight Elevators. Landlord shall,
consistent with its obligations to other tenants of the Building, make the freight elevator reasonably available to Tenant in connection with initial decorating, furnishing and moving into the Expansion Premises. 

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

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

  
 EXHIBIT B 

  
 -3- 

 6.5    Tenant’s Agents. All
contractors, subcontractors, laborers, materialmen, and suppliers retained by Tenant in connection with the Tenant Improvements shall be union labor in compliance with the then existing master labor agreements. 

6.6    Time of the Essence in This Tenant Work Letter. Unless otherwise indicated, all
references herein to a “number of days” shall mean and refer to calendar days. 

6.7    Tenant’s Lease Default. Notwithstanding any provision to the contrary contained
in the Lease, as hereby amended, if an event of default as described in the Lease, as hereby amended, or a default by Tenant under this Tenant Work Letter, has occurred at any time on or before the Substantial Completion of the Tenant Improvements,
then (i) in addition to all other rights and remedies granted to Landlord pursuant to the Lease, as hereby amended, Landlord shall have the right to cause Contractor to cease the construction of the Tenant Improvements (in which case, Tenant
shall be responsible for any delay in the Substantial Completion of the Tenant Improvements caused by such work stoppage as set forth in Section 5 of this Tenant Work Letter), and (ii) all other obligations of Landlord
under the terms of this Tenant Work Letter shall be forgiven until such time as such default is cured pursuant to the terms of the Lease, as hereby amended. 

6.8    Cooperation by Tenant. Tenant acknowledges that the timing of the completion of the
Approved Work Drawings and the Tenant Improvements is of the utmost importance to Landlord. Accordingly, Tenant hereby agrees to fully and diligently cooperate with all reasonable requests by Landlord in connection with or related to the design and
construction of the Tenant Improvements, and in connection therewith, shall respond to Landlord’s requests for information and/or approvals, except as specifically set forth herein to the contrary, within five (5) business days following
request by Landlord.
