Form of Option Agreement under 2006 Equity Incentive Plan

 Exhibit 10.14 
 HYPERION THERAPEUTICS, INC. 

2006 EQUITY INCENTIVE PLAN 

OPTION AGREEMENT 
 (INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK OPTION) 

Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement, Hyperion Therapeutics,
Inc. (the “Company”) has granted you an option under its 2006 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in your Grant
Notice at the exercise price indicated in your Grant Notice. Defined terms not explicitly defined in this Option Agreement but defined in the Plan shall have the same definitions as in the Plan. 

The details of your option are as follows: 
 1. VESTING. Subject to the limitations contained herein, your option will vest as provided in your Grant Notice, provided that vesting will cease upon the termination
of your Continuous Service. 
 2. NUMBER OF SHARES AND
EXERCISE PRICE. The number of shares of Common Stock subject to your option and your exercise price per share referenced in your Grant Notice may be adjusted from time to time for Capitalization
Adjustments. 
 3. EXERCISE RESTRICTION FOR
NON-EXEMPT EMPLOYEES. In the event that you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (i.e., a
“Non-Exempt Employee”), you may not exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant specified in your Grant Notice, notwithstanding any other
provision of your option. 
 4. EXERCISE PRIOR TO VESTING
(“EARLY EXERCISE”). If permitted in your Grant Notice (i.e., the “Exercise Schedule” indicates that “Early Exercise” of your option is permitted) and subject to the provisions of
your option, you may elect at any time that is both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the nonvested portion of your option;
provided, however, that: 
 (a) a partial exercise of your option shall be deemed to cover first
vested shares of Common Stock and then the earliest vesting installment of unvested shares of Common Stock; 

(b) any shares of Common Stock so purchased from installments that have not vested as of the date of exercise shall
be subject to the purchase option in favor of the Company as described in the Company’s form of Early Exercise Stock Purchase Agreement; 

  
 1. 

 (c) you shall enter into the Company’s form of Early Exercise
Stock Purchase Agreement with a vesting schedule that will result in the same vesting as if no early exercise had occurred; and 
 (d) if your option is an Incentive Stock Option, then, to the extent that the aggregate Fair Market Value (determined at the time of grant) of the shares of Common Stock with respect to which your
option plus all other Incentive Stock Options you hold are exercisable for the first time by you during any calendar year (under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions
thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 
 5. METHOD OF PAYMENT. Payment of the exercise price is due in full upon exercise of all or any part of your option. You may elect to make
payment of the exercise price in cash or by check or in any other manner permitted by your Grant Notice, which may include one or more of the following; 

(a) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall
Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of
irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. 

(b) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall
Street Journal, by delivery to the Company (either by actual delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair
Market Value on the date of exercise. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the
redemption of the Company’s stock. 
 6. WHOLE SHARES. You may exercise
your option only for whole shares of Common Stock. 
 7. SECURITIES LAW
COMPLIANCE. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or,
if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option also must comply with other
applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 

  
 2. 

 8. TERM. You may not exercise your option before
the commencement or after the expiration of its term. The term of your option commences on the Date of Grant and expires upon the earliest of the following: 
 (a) three (3) months after the termination of your Continuous Service for any reason other than your Disability or death, provided that if during any part of such three (3) month period
your option is not exercisable solely because of the condition set forth in the section above relating to “Securities Law Compliance,” your option shall not expire until the earlier of the Expiration Date or until it shall have been
exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; 

(b) twelve (12) months after the termination of your Continuous Service due to your Disability; 

(c) eighteen (18) months after your death if you die either during your Continuous Service or within three
(3) months after your Continuous Service terminates; 
 (d) the Expiration Date indicated in your
Grant Notice; or 
 (e) the day before the tenth (10th) anniversary of the Date of Grant. 

If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages associated with an Incentive Stock
Option, the Code requires that at all times beginning on the date of grant of your option and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the Company or an Affiliate, except in
the event of your death or your permanent and total disability, as defined in Section 22(e) of the Code. (The definition of disability in Section 22(e) of the Code is different from the definition of the Disability under the Plan.) The
Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an Incentive Stock Option if you continue to provide services to the
Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment with the Company or an Affiliate terminates. 

9. EXERCISE. 
 (a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during its term by delivering a Notice of Exercise (in a form
designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then
require. 
 (b) By exercising your option you agree that, as a condition to any exercise of your option,
the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option, (2) the lapse of any
substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. 

  
 3. 

 (c) If your option is an Incentive Stock Option, by exercising your
option you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the
date of your option grant or within one (1) year after such shares of Common Stock are transferred upon exercise of your option. 
 (d) By exercising your option you agree that you shall not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction
with the same economic effect as a sale, any shares of Common Stock or other securities of the Company held by you, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed
under the Securities Act or such longer period as necessary to permit compliance with NASD Rule 2711 and similar or successor regulatory rules and regulations (the “Lock-Up Period”); provided, however, that nothing
contained in this section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You further agree to execute and deliver such other agreements as may be reasonably requested by the Company
and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to your shares of
Common Stock until the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 9(d) and shall have the right, power and authority to enforce the provisions hereof as though they
were a party hereto. 
 10. TRANSFERABILITY. Your option is not transferable, except by
will or by the laws of descent and distribution and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who,
in the event of your death, shall thereafter be entitled to exercise your option. In addition, if permitted by the Company you may transfer your option to a trust if you are considered to be the sole beneficial owner (determined under
Section 671 of the Code and applicable state law) while the option is held in the trust, provided that you and the trustee enter into a transfer and other agreements required by the Company. 

11. RIGHT OF FIRST REFUSAL. Shares of Common Stock that
you acquire upon exercise of your option are subject to any right of first refusal that may be described in the Company’s bylaws in effect at such time the Company elects to exercise its right; provided, however, that if your option is
an Incentive Stock Option and the right of first refusal described in the Company’s bylaws in effect at the time the Company elects to exercise its right is more beneficial to you than the right of first refusal described in the Company’s
bylaws on the Date of Grant, then the right of first refusal described in the Company’s bylaws on the Date of Grant shall apply. The Company’s right of first refusal shall expire on the Listing Date. For purposes of this Agreement, Listing
Date shall mean the first date upon which any security of the Company is listed (or approved for listing) upon notice of issuance on a national securities exchange or quotation system. 

12. RIGHT OF REPURCHASE. To the extent provided in the Company’s
bylaws in effect at such time the Company elects to exercise its right, the Company shall have the right to repurchase all or any part of the shares of Common Stock you acquire pursuant to the exercise of your option. 

  
 4. 

 13. OPTION NOT A SERVICE
CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an
Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers or Employees to continue any
relationship that you might have as a Director or Consultant for the Company or an Affiliate. 
 14.
WITHHOLDING OBLIGATIONS. 
 (a) At the time you exercise your option, in
whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless
exercise” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of
the Company or an Affiliate, if any, which arise in connection with the exercise of your option. 
 (b)
Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon
the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as
may be necessary to avoid classification of your option as a liability for financial accounting purposes). If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share
withholding pursuant to the preceding sentence shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect
to which such determination is otherwise deferred, to accelerate the determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld
solely from fully vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure
shall be your sole responsibility 
 (c) You may not exercise your option unless the tax withholding
obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares
of Common Stock or release such shares of Common Stock from any escrow provided for herein unless such obligations are satisfied. 
 15. NOTICES. Any notices provided for in your option or the Plan shall be given in writing and shall be deemed effectively given upon receipt or in the case of notices
delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 

  
 5. 

 16. GOVERNING PLAN
DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations,
which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control.

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
Premises shall be delivered to Tenant with all electrical service, plumbing (including water and waste plumbing), and HVAC serving and located in the Premises (hereinafter, the “Base Building Systems”) in operating condition and working
order. In the event Landlord has actual knowledge or receives from Tenant Notice, prior to the Commencement Date, of a problem with the operating condition or working order of any such Base Building Systems, Landlord will promptly proceed to correct
or remediate such condition in such manner as Landlord determines is appropriate to cure such condition. Subject to the foregoing, Landlord shall have no liability to Tenant, and Tenant shall have no remedy, for a breach of the foregoing covenant,
and no such condition shall operate to otherwise delay the Commencement Date or otherwise affect the validity of this Lease. Except as specifically set forth above with respect to the operating condition of the Base Building Systems in the Premises,
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. Notwithstanding the foregoing, Tenant hereby acknowledges and
agrees that (i) the Premises are not new, (ii) that Landlord is providing Tenant with the Tenant Improvement Allowance in order that Tenant may repair and refurbish the Premises, (iii) that other than providing the Tenant Improvement
Allowance, and agreeing that the Base Building Systems serving and located in the Premises, as specified above, will be in operating condition and working order, Tenant has agreed to accept the Premises in “AS IS WHERE IS” condition and
repair, and (iv) that Tenant, as part of the Tenant Improvement Allowance, or otherwise at its sole cost and expense, shall be responsible for repairing or replacing any damaged or broken ceiling lighting, electrical outlets,

  
 -4-

 
ceiling tiles, casework, doors, or other items in the Premises. Notwithstanding the foregoing, Landlord shall be responsible, for a period of six (6) months following the Commencement Date,
for providing that any Base Building systems serving the Premises (for example, the HVAC system, or the electrical system, serving the Premises), as well as any structural components of the Building, are in good working order and repair. 

1.1.2 The Building and The Project. The Premises are a part of the building set forth in Section 2.1 of
the Summary (the “Building”). The Building is part of an office project known as “Gateway Center.” The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas,
(ii) the land (which is improved with landscaping, subterranean parking facilities and other improvements) upon which the Building and the Common Areas are located, (iii) those certain other office buildings located in the vicinity of the
Building and known as 611 and/or 651 Gateway Boulevard, respectively, and the land upon which such office 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. 
 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, including certain areas designated for the exclusive use of certain tenants, or to be shared by Landlord and
certain tenants, are collectively referred to herein as the “Common Areas”). The Common Areas shall consist of the “Project Common Areas” and the “Building Common Areas.” The term “Project Common
Areas,” as used in this Lease, shall mean the portion of the Project designated as such by Landlord, which Project Common Areas may include, from time to time, in Landlord’s sole discretion, a conference center and other amenities. The
term “Building Common Areas,” as used in this Lease, shall mean the portions of the Common Areas located within the Building designated as such by Landlord. The manner in which the Common Areas are maintained and operated shall be
at the reasonable discretion of Landlord in accordance with Section 6.1.7 herein and the use thereof shall be subject to such 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 Landlord shall use commercially reasonable efforts not to materially and adversely affect Tenant’s operations
in, or access to, the Premises as a result thereof. 
 1.2 Verification of Rentable Square Feet of Premises and
Building. For purposes of this Lease, “rentable square feet” in the Premises and the Building, as the case may be, shall be calculated pursuant to Landlord’s then current method for measuring rentable square footage.
Landlord and Tenant hereby stipulate and agree that the rentable area of the Premises is as set forth in Section 2.2 of the Summary. Notwithstanding the foregoing, if Landlord, at its option, re-measures the Premises in connection with a
re-measurement of the Building to determine the exact amount of rentable area contained therein pursuant to Landlord’s then current method for measuring rentable square footage, or if the rentable area of the Premises and/or the Building shall
hereafter change due to subsequent alterations and/or other modifications to the Premises and/or the Building, then the rentable area of the Premises and/or the Building, as the case may be, shall be appropriately adjusted as of the date of such
re-measurement or such 

  
 -5-

 
alteration or other modification, based upon the written verification by Landlord’s space planner of such revised rentable area. In the event of any such adjustment to the rentable area of
the Premises, and/or the Building, all amounts, percentages and figures appearing or referred to in this Lease based upon such rentable area (including, without limitation, the amounts of the “Rent” and the “Security Deposit,” as
those terms are defined in Article 4 and Article 21 of this Lease, respectively, and “Tenant’s Share,” as that term is defined in Section 4.2.9 of this Lease) shall be modified in accordance with such determination; provided,
however, if any such adjustment to the rentable area of the Premises and/or Building results from a re-measurement thereof conducted at Landlord’s option, then, notwithstanding anything to the contrary contained in this Section 1.2,
“Base Rent,” as defined in Article 3 of this Lease, shall not be modified in accordance with such determination, 

ARTICLE 2  
 LEASE TERM 
 2.1 Initial 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 commence on the “Lease Commencement Date,” as that term is defined below, and shall terminate on the
“Lease Expiration Date,” as that term is defined below, unless this Lease is sooner terminated as hereinafter provided. If Landlord is unable for any reason to deliver possession of the Premises to Tenant on the Anticipated Lease
Commencement Date set forth in Section 3.2 of the Summary, then Landlord shall not be subject to any liability for its failure to do so, and such failure shall not affect the validity of this Lease or the obligations of Tenant hereunder:
provided, however, that, subject to Force Majeure, in the event that Landlord has not “Substantially Completed” (as defined in Exhibit B attached hereto) the “Tenant Improvements” (as defined in Exhibit
B attached hereto) and delivered the Tenant Improvements to Tenant within three (3) months following Landlord’s obtaining of a “Building Permit” (as defined in Exhibit B attached hereto) for the Tenant
Improvements, Tenant may, upon not less than ten (10) business days prior written notice to Landlord, elect to terminate this Lease, unless Landlord shall, within such ten business day period, deliver to Tenant the Premises with the Tenant
Improvements Substantially Completed. Landlord hereby agrees to use commercially reasonable efforts to diligently proceed to obtain a Building Permit in accordance with the procedure outlined in Exhibit B attached hereto.
Notwithstanding anything to the contrary contained in Section 3.2 of the Summary or elsewhere in this Lease, the “Lease Commencement Date” shall be the date upon which the Tenant Improvements are Substantially Completed and are
delivered to Tenant for occupancy (which Tenant acknowledges may occur before, on or after the Anticipated Lease Commencement Date set forth in Section 3.2 of the Summary). Notwithstanding anything to the contrary contained in Section 3.3
of the Summary or elsewhere in this Lease, Landlord and tenant hereby agree that the “Rent Commencement Date” shall be the Lease Commencement Date. Notwithstanding anything to the contrary contained in Section 3.4 of the
Summary or elsewhere in this Lease, the “Lease Expiration Date” shall be as follows: (A) if the Lease Commencement Date shall be the first day of a calendar month, then the day immediately preceding the fourth
(4th) anniversary of the Lease Commencement Date; or (B) if the Lease Commencement Date shall be other than the first day of a calendar month, then the last day of the month in which the fourth (4th) anniversary of the Lease
Commencement Date occurs. For purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12)

  
 -6-

 
month period during the Lease Term, provided that the first Lease Year shall include any partial month at the commencement of the Lease Term. 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 ten (10) days of receipt
thereof; provided, however, Tenant’s failure to execute and return such notice to Landlord within such time shall be conclusive upon Tenant that the information set forth in such notice is as specified therein. 

2.2 Option Right. Landlord hereby grants to the originally named Tenant herein (“Original Tenant”) and any
Permitted Transferee one (1) option to extend the Lease Term for a period of three (3) years (“Option Term”). The Option Term shall be exercisable only by written notice delivered by the Original Tenant or a Permitted Transferee
to Landlord as provided in Section 2.2.2 below, provided that, as of the date of delivery of such notice, this Lease is in full force and effect, and there is no default by the Original Tenant or a Permitted Transferee under Section 19.1
of this Lease. The rights contained in this Section 2.2 shall be personal to the Original Tenant or a Permitted Transferee and may be exercised only by the Original Tenant and a Permitted Transferee (and not by any other assignee, sublessee or
other Transferee, as that term is defined in Section 14.1, of the Original Tenant’s interest in this Lease). Upon the proper exercise of such option to extend, and provided that, at Landlord’s election, as of the end of the Lease Term
there is no default under Section 19.1 of this Lease by the Original Tenant or a Permitted Transferee under this Lease and the other conditions to exercise of such option to extend listed in this Section 2.2 are still true, the Lease Term,
as it applies to the Premises, shall be extended for a period of three (3) years. 
 2.2.1 Exercise of
Option. If Tenant wishes to exercise the Option Term contained in this Section 2.2, then the Original Tenant shall deliver written notice to Landlord not more than twelve (12) months nor less than nine (9) months prior to the
expiration of the initial Lease Term stating that the Original Tenant is exercising its option for the entire Premises. 
 2.2.2 Base Rent During Option Term. The Base Rent payable during the Option Term shall be adjusted to equal the fair rental renewal value (as herein defined) for the Premises as of the date
of the commencement of the Option Term pursuant to the procedures set forth herein. 
 (i) Fair rental renewal
value shall mean the monthly Base Rent per square foot of rentable area prevailing for lease renewals for “Comparable Renewal Space” as of the date the Option Term commences, multiplied by the rentable area of the Premises. 

(ii) Comparable Renewal Space means space in newer (built since 1990) Class A high rise office buildings in the
cities of South San Francisco and Brisbane that is comparable to the Premises, the lease for which is then being or has recently been renewed. 
 (iii) In determining fair rental renewal value, the following factors shall be taken into account: (a) the amount of tenant improvement allowances provided for the Comparable Renewal Space, but only
to the extent the quality level of the improvements in the Comparable Renewal Space after refurbishment exceeds the quality level of existing 

  
 -7-

 
improvements in the Premises; (b) the usability of the existing improvements in the Premises in comparison with the usability of the existing improvements in the Comparable Renewal Space;
(c) the size, location and the floor level of the Premises compared with the Comparable Renewal Space; and (d) the duration of the Option Term in relationship to the duration of the renewal term for the Comparable Renewal Space.

 (iv) Landlord shall notify Tenant of its determination of fair rental renewal value on or about the
commencement of the Option Term. If Tenant in good faith disputes Landlord’s determination of fair rental renewal value and if such dispute is not resolved by negotiation between the parties within thirty (30) days after Landlord’s
notice is given, fair rental renewal value shall be as determined by appraisal as provided below. Tenant shall pay Base Rent when due based on Landlord’s determination of fair rental renewal value, subject to retroactive adjustment between the
parties in the event the determination by appraisal is different from Landlord’s determination. 
 (v) If
fair rental renewal value is to be determined by appraisal, within ten (10) business days after the expiration of the thirty (30) day negotiation period, Landlord and Tenant shall each appoint as an appraiser a real estate broker with at
least five (5) years of recent continuous experience in leasing office space in South San Francisco or a similarly qualified real estate appraiser, and give notice of such appointment to the other. If either Landlord or Tenant shall fail timely
to appoint an appraiser, the appointed appraiser shall select the second appraiser within ten (10) business days after the failure of Landlord or Tenant, as the case may be, to appoint. Such appraisers shall, within thirty (30) days after
the appointment of the last of them to be appointed, complete their determination of fair rental renewal value based on the standards set forth in subparagraph (iii) above, as applicable, and submit their appraisal reports separately and in
writing to Landlord and Tenant. If Landlord and Tenant do not mutually approve one of the two determinations within fifteen (15) days thereafter, the two appraisers shall, within ten (10) business days after expiration of the fifteen
(15) day period, appoint a third appraiser who shall be similarly qualified. If the two appraisers shall be unable to agree timely on the selection of a third appraiser then either appraiser, on behalf of both, may request such appointment by
such neutral arbitration provider as both parties shall agree to. Such appraiser shall, within thirty (30) days after his or her appointment, make an independent determination of fair rental renewal value based on the standards set forth in
subparagraph (iii) above, as applicable, and shall select the one of the determinations by the other two appraisers that is the closer to his or her determination. Fair rental renewal value shall be that set forth in the determination so
selected. Landlord and Tenant shall each pay the fees of their respective appraisers and the fees of the third appraiser shall be paid one-half by Landlord and one-half by Tenant. Base Rent for the Option Term determined in accordance with this
Section 2.2.3 shall be payable in accordance with the provisions of Article 3. 
 2.3 Phased Possession.
Landlord hereby agrees that Tenant may occupy a portion of the Premises during the period that Landlord is constructing the Tenant Improvements in the other portion of the Premises pursuant to Exhibit B attached hereto (hereinafter,
the “Phased Possession.”) Landlord and Tenant hereby acknowledge and agree that (i) the portion of the Premises, and (ii) the size of such portion of the Premises, to be occupied by Tenant during such Phased Possession has
yet to be determined, and that once Landlord and Tenant have determined the portion of the Premises, and the size of such portion of the Premises, and Landlord is 

  
 -8-

 
prepared to commence the Tenant Improvements in the Premises, Landlord shall provide Tenant with written Notice that a portion of the Premises is available for Tenant’s Phased Possession
(hereinafter, the “Phase I Premises”) and thereafter Tenant may enter into possession of the Phase I Premises prior to the Commencement Date of this Lease. 
 During the period that Tenant is in possession of the Phase I Premises, Landlord shall be constructing the Tenant Improvements in the remainder of the Premises (hereinafter, the “Phase II
Premises.”) Once Landlord Substantially Completes construction of the Tenant Improvements in the Phase II Premises, Tenant shall move into the Phase II Premises as quickly as reasonably practicable, and Landlord shall proceed to
Substantially Complete construction of the Tenant Improvements in the Phase I Premises. Tenant hereby agrees that it shall not in any way interfere with the progress of Landlord’s work in the Premises by such Phased Possession, Once the Tenant
Improvements are Substantially Completed in both the Phase I Premises and the Phase II Premises, Landlord shall deliver the entire Premises to Tenant as specified in Exhibit B attached hereto. 

During any period of Phased Possession that Tenant occupies all or any portion of the Premises, Tenant shall pay Base Rent in accordance
with the Annual Base Rental Rate Per Rentable Square Foot specified for the First Lease Year as set forth in Section 4 of the Summary, multiplied by number of rentable square feet of the Premises occupied by Tenant, as Landlord shall reasonably
determine. In addition, during the course of such Phased Possession, all the terms and conditions of this Lease, except for Lease commencement, shall apply, particularly with reference to indemnity by Tenant of Landlord under Article 10 herein for
all occurrences within or about the Phase I Premises and/or the Phase II Premises, as applicable (whichever the Tenant is occupying); provided, however, that during any such Phased Possession, Landlord shall not be required to provide any janitorial
services to the Premises, and Tenant hereby acknowledges and agrees that some or all of the other services that Landlord provides to the Premises as specified in Article 6 and Exhibit F, respectively, below, may be
interrupted or delayed as a result of Landlord’s construction work in the Premises, Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service, or
for any diminution in the quality or quantity thereof; 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 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 set forth in Article 6 and Exhibit F during any period of Phased
Possession. 
 2.4 Right of First Offer. When the existing tenant’s lease expires in July of 2009 on Suite
210 (the “Offer Space”), Landlord shall give written notice to Tenant (the “Offer Notice”) that such Offer Space is available for lease. Landlord’s Offer Notice shall specify the size of the Offer Space, when the Offer Space
will be available for lease, the term of the lease of such Offer Space, any tenant improvement allowance or other economic inducements offered in connection with the Offer Space, and the Base Rent for the Offer Space. Tenant shall have five
(5) business days following receipt of the Offer Notice to notify Landlord in writing of whether or not Tenant wishes to lease the Offer Space on the terms and conditions set forth in the Offer Notice. In the

  
 -9-

 
event that Tenant shall fail to respond to the Offer Notice in writing within such five (5) business day period, or shall respond in writing but propose different terms for the lease of the
Offer Space than those specified in the Offer Notice, including without limitation a different term, size or rental rate, Landlord shall have no obligation to lease the Offer Space to Tenant and may thereafter lease the Offer Space to any other
interested party on whatever terms and conditions Landlord shall desire, in its sole and absolute discretion, notwithstanding the terms set forth in the Offer Notice. In the event that, following receipt of the Offer Notice, Tenant shall fail to
lease the Offer Space, Landlord shall have no further obligation to Tenant with respect to any Offer Space and the rights granted herein shall be null and void and of no further force or effect. In the event that Tenant timely and properly responds
to the Offer notice and agrees to lease the Offer Space on the terms and conditions contained therein, Landlord and Tenant agree to execute an amendment to this Lease, including the Offer Space within the Premises and otherwise amending the terms
and provisions hereof to include the provisions of the Offer Notice herein.

annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis. 
 ARTICLE 4  
 ADDITIONAL RENT 

4.1 General Terms. In addition to paying the Base Rent specified in Article 3 of this Lease, Tenant shall pay
“Tenant’s Share” of the annual “Building Direct Expenses,” as those terms are defined in Sections 4.2.9 and 4.2.2 of this Lease, respectively, which are in excess of the amount of Building Direct Expenses applicable to the
“Base Year,” as that term is defined in Section 4.2.1, below; provided, however, that in no event shall any decrease in Building Direct Expenses for any “Expense Year,” as that term is defined in Section 4.2.6 below,
below Building Direct Expenses for the Base Year entitle Tenant to any decrease in Base Rent or any credit 

  
 -10-

 
against sums due under this Lease. Such payments by Tenant, together with any and all other amounts payable by Tenant to Landlord pursuant to the terms of this Lease, are hereinafter collectively
referred to as the “Additional Rent,” and the Base Rent and the Additional Rent are herein collectively referred to as “Rent.” All amounts due under this Article 4 as Additional Rent shall be payable for the same
periods and in the same manner as the Base Rent. Without limitation on other obligations of Tenant which survive the expiration of the Lease Term, the obligations of Tenant to pay the Additional Rent provided for in this Article 4 shall survive the
expiration of the Lease Term. Landlord may upon expiration of the Lease Term deliver to Tenant an estimate of any Base Rent, Additional Rent or other obligations outstanding, and Landlord may either deduct such amount from any funds otherwise
payable to Tenant upon expiration or require Tenant to pay such funds immediately. Landlord shall make necessary adjustments for differences between actual and estimated Additional Rent in accordance with Section 4.4, below.

that portion of “Tax Expenses”, as that term is defined in Section 4.2.8 below, allocated to the tenants of the Building pursuant to the terms of Section 4.3.1 below. 

4.2.5 “Direct Expenses” shall mean “Operating Expenses” and “Tax Expenses.”

 4.2.6 “Expense Year” shall mean each calendar year in which any portion of the Lease Term
falls, through and including the calendar year in which the Lease Term expires, provided that Landlord, upon notice to Tenant, may change the Expense Year from time to time to any other twelve (12) consecutive month period, and, in the event of
any such change, Tenant’s Share of Building Direct Expenses shall be equitably adjusted for any Expense Year involved in any such change. 
 4.2.7 “Operating Expenses” shall mean all expenses, costs and amounts of every kind and nature which Landlord pays or accrues during any Expense Year because of or in connection with the
ownership, management, maintenance, security, repair, replacement (to the extent involving a capital expenditure, subject to Subparagraph (xiii), below), restoration (to the extent involving a capital expenditure, subject to Subparagraph (xiii),

 -12-

 
life as Landlord shall reasonably determine; (xiv) costs, fees, charges or assessments imposed by, or resulting from any mandate imposed on Landlord by, any federal, state or local

expenditures incurred in connection with the Project, including, without limitation, costs of signs in, on or about the Project identifying or promoting the Project; and (xvi) payments under any easement, license, operating agreement,

 If Landlord is not furnishing any particular work or service (the cost of which, if performed by Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform such work or
service in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount equal to the additional Operating Expenses which would reasonably have been incurred during such period by Landlord if it had at
its own expense furnished such work or service to such tenant. If the Project is not at least one hundred percent (100%) occupied during all or a portion of the Base Year or any Expense Year, Landlord may elect to make an appropriate adjustment
to the components of Operating Expenses for such year to determine the amount of Operating Expenses that would have been incurred had the Project been one hundred percent (100%) occupied; and the amount so determined shall be deemed to have
been the amount of Operating Expenses for such year. Operating Expenses for the Base Year shall not include market-wide labor-rate increases due to extraordinary circumstances, including, but not limited to, boycotts and strikes, and utility rate
increases due to extraordinary circumstances including, but not limited to, conservation surcharges, boycotts, embargoes or other shortages, or amortized costs relating to capital improvements. In no event shall the components of Direct Expenses for
any Expense Year related to electrical costs be less than the components of Direct Expenses related to electrical costs in the Base Year. 
 Notwithstanding the foregoing, Operating Expenses shall not include (1) the costs of repair to the Building and the Project and other costs and expenses to the extent that Landlord is actually
reimbursed by insurance or warranty proceeds; (2) the costs of marketing or advertising, real estate brokerage and leasing commissions and legal fees incurred in negotiating and preparing lease documents related to the Building and the Project;
(3) the cost of altering, improving or renovating space in the Building and the Project which is not Common Area and does not serve the Building or the Project as a whole or tenants generally; (4) the cost of utilities, special services
and other benefits (including but not limited to after-hours HVAC, supplemental condenser water, etc.) provided to any one tenant of the Building or the Project but not generally provided to all tenants of the Building or the Project;
(5) improvements made for tenants or other occupants in the Building or the Project or incurred in renovating or otherwise improving, decorating, painting, or redecorating vacant space for tenants or other occupants of the Building or the
Project; (6) depreciation charges, except as otherwise stated hereinabove; (7) principal, interest, points and fees on debt or amortization payments on any real property mortgages or deeds of trust; (8) ground rental payments;
(9) expenses (including legal fees and related costs) incurred in enforcing obligations of tenants of the Building or the Project; (10) costs paid to Landlord or to affiliates of Landlord for services in the Building or the Project to the
extent the 

  
 -13-

 
same materially exceed or would materially exceed the costs for such services if rendered by first class unaffiliated third parties on a competitive basis (other than the management fee paid to
Landlord’s affiliate, which shall not be included in this exclusion); (11) costs, other than those incurred in ordinary maintenance, for sculpture, paintings or other objects of art; (12) costs of correcting defects in any portion of

future Building repair or replacement or any contingency fund; (17) costs associated with the operation of the business of the corporation which constitutes Landlord, as the same are distinguished from the costs of operation of the Building or
the Project, including corporate accounting and legal matters; (18) costs of defending any lawsuits with any mortgagee (except as the actions of Tenant may be the issue); (19) costs of selling, syndicating, financing, mortgaging or
hypothecating any of Landlord’s interest in the Building or the Project; and (20) costs (including attorneys’ fees and costs of settlement, judgments and payments in lieu thereof) arising from claims, disputes or potential disputes
respecting Landlord other than in connection with Building or the Project operations. 
 Landlord hereby
represents and warrants to Tenant that Landlord has not received any notice from any governmental authority having jurisdiction over the Project that the Premises, Building or Project is (a) not in compliance with the ADA (as defined in
Section 24.2, below), or (b) not in compliance with the statutes, laws and regulations pertaining to Hazardous Substances (as defined in Section 5.2, below). 

4.2.8 Taxes. 
 4.2.8.1 “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal taxes, fees, charges or other impositions of every kind and nature, whether general,
special, ordinary or extraordinary (including, without limitation, real estate taxes, general and special assessments, transit taxes, business taxes, leasehold taxes or taxes based upon the receipt of rent, including gross receipts or sales taxes
applicable to the receipt of rent, unless required to be paid by Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment, appurtenances, furniture and other personal property used in
connection with the Project, or any portion thereof), which shall be paid or accrued during any Expense Year (without regard to any different fiscal year used by such governmental or municipal authority) because of or in connection with the
ownership, leasing and operation of the Project, or any portion thereof. Tax Expenses for any calendar year shall be Tax Expenses which are due for payment or paid in such year, rather than Tax Expenses which are assessed or become a lien during
such year. 
 4.2.8.2 Tax Expenses shall include, without limitation: (i) Any tax on the rent, right to rent
or other income from the Project, or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any
assessment, tax, fee, levy or charge previously included within the definition of real property tax, it being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the State of California in

  
 -14-

 
the June 1978 election (“Proposition 13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection,
street, sidewalk and road maintenance, refuse removal and for other governmental services formerly provided without charge to property owners or occupants, and, in further recognition of the decrease in the level and quality of governmental services
and amenities as a result of Proposition 13, Tax Expenses shall also include any governmental or private assessments or the Project’s contribution towards a governmental or private cost-sharing agreement for the purpose of augmenting or
improving the quality of services and amenities normally provided by governmental agencies; (iii) Any assessment, tax, fee, levy, or charge allocable to or measured by the area of the Premises, the tenant improvements in the Premises, or the
Rent payable hereunder, including, without limitation, any business or gross income tax or excise tax with respect to the receipt of such rent, or upon or with respect to the possession, leasing, operating, management, maintenance, alteration,
repair, use or occupancy by Tenant of the Premises, or any portion thereof; (iv) Any assessment, tax, fee, levy or charge, upon this transaction or any document to which Tenant is a party, creating or transferring an interest or an estate in
the Premises; and (v) All of the real estate taxes and assessments imposed upon or with respect to the Building and all of the real estate taxes and assessments imposed on the land and improvements comprising the Project. 

4.2.8.3 Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for
any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord promptly following Landlord’s written demand Tenant’s Share of any such increased Tax Expenses
included by Landlord as Building Tax Expenses pursuant to the terms of this Lease. Notwithstanding anything to the contrary contained in this Section 4.2.8 (except as set forth in Section 4.2,8.1, above), there shall be excluded from Tax
Expenses (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net
income (as opposed to rents, receipts or income attributable to operations at the Project), (ii) any items included as Operating Expenses, and (iii) any items paid by Tenant under Section 4.5 of this Lease. 

4.2.8.4 Notwithstanding anything to the contrary set forth in this Lease, the amount of Tax Expenses for the Base Year and
any Expense Year shall be calculated without taking into account any decreases in real estate taxes obtained in connection with Proposition 8, and, therefore, the Tax Expenses in the Base Year and/or an Expense Year may be greater than those
actually incurred by Landlord, but shall, nonetheless, be the Tax Expenses due under this Lease; provided that (i) any costs and expenses incurred by Landlord in securing any Proposition 8 reduction shall not be deducted from Tax Expenses nor
included in Direct Expenses for purposes of this Lease, and (ii) tax refunds under Proposition 8 shall not be deducted from Tax Expenses nor refunded to Tenant, but rather shall be the sole property of Landlord. Landlord and Tenant acknowledge
that the preceding sentence is not intended to in any way affect (A) the inclusion in Tax Expenses of the statutory two percent (2.0%) annual increase in Tax Expenses (as such statutory increase may be modified by subsequent legislation),
or (B) the inclusion or exclusion of Tax Expenses pursuant to the terms of Proposition 13. Notwithstanding the foregoing, upon a reassessment of the Building and/or the Project pursuant to the terms of Proposition 13 (a
“Reassessment”) occurring after the Base Year which results in a decrease in 

  
 -15-

 
Tax Expenses, the component of Tax Expenses for the Base Year which is attributable to the assessed value of the Building and/or the Project under Proposition 13 prior to the Reassessment
(without taking into account any Proposition 8 reductions) (the “Base Year Prop 13 Taxes”) shall be reduced, if at all, for the purposes of comparison to all subsequent Expense Years (commencing with the Expense Year in which the
Reassessment takes place) to an amount equal to the real estate taxes based upon such Reassessment, and if thereafter, in connection with a subsequent Reassessment, the assessed value of the Building and/or the Project under Proposition 13 shall
increase, the current Base Year Prop 13 Taxes shall be increased for purposes of comparison to all subsequent Expense Years (commencing with the Expense Year in which the Reassessment takes place) to an amount equal to the lesser of the original
Base Year Prop 13 Taxes and an amount equal to the real estate taxes based upon such Reassessment. 
 4.2.9
“Tenant’s Share” shall mean the percentage set forth in Section 6 of the Summary. Tenant’s Share was calculated by multiplying the number of rentable square feet of the Premises, as set forth in Section 2.2 of
the Summary, by 100, and dividing the product by the total number of rentable square feet in the Building. If Tenant’s Share shall be adjusted in accordance with section 1.2, above, at any time after the Base Year, then, as to the Expense Year
in which the change occurs, Tenant’s Share for such Expense Year shall be determined on the basis of the number of days during such Expense Year that such Tenant’s Share was in effect. 

4.3 Allocation of Direct Expenses. 
 4.3.1 Method of Allocation. 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 tenants of the Building and the tenants of the other buildings in the Project. Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consists 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 tenants of the Building (as opposed to the tenants of any other
buildings in the Project) and such portion shall be the Building Direct Expenses for purposes of this Lease. Such portion of Direct Expenses allocated to the tenants of 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. 
 4.3.2
Cost Pools. Landlord shall have the right, from time to time, to equitably allocate some or all of the Direct Expenses for the Project among different portions or occupants of the Project (the “Cost Pools”), in
Landlord’s reasonable discretion. Such Cost Pools may include, but shall not be limited to, the office space tenants of a building of the Project or of the Project, and the retail space tenants of a building of the Project or of the Project.
The Direct Expenses allocable to each such Cost Pool shall be allocated to such Cost Pool and charged to the tenants within such Cost Pool in an equitable manner. 
 4.4 Calculation and Payment of Additional Rent. If for any Expense Year ending or commencing within the Lease Term, Tenant’s Share of Building Direct Expenses for such Expense Year
exceeds Tenant’s Share of Building Direct Expenses applicable to the Base Year, then Tenant shall pay to Landlord, in the manner set forth in Section 4.4.1, below, and as Additional Rent, an amount equal to the excess (the
“Excess”). 

  
 -16-

 4.4.1 Statement of Actual Building Direct Expenses and Payment by
Tenant. Landlord shall give to Tenant following the end of each Expense Year, a statement (the “Statement”) which shall state the Building Direct Expenses incurred or accrued for such preceding Expense Year, and which shall
indicate the amount of the Excess. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, if an Excess is present, Tenant shall pay, with its next installment of Base Rent due or within thirty (30) days,
whichever is earlier, the full amount of the Excess for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Excess,” as that term is defined in Section 4.4.2, below. If the amounts paid by Tenant
during an Expense Year as Estimated Excess exceed the Excess for such Expense Year, then such difference shall be reimbursed by Landlord to Tenant, provided that any such reimbursement, at Landlord’s option, may be credited against the
Additional Rent next coming due under this Lease unless the Lease Term has expired, in which event Landlord shall refund the appropriate amount to Tenant. 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 Building Direct Expenses for the
Expense Year in which this Lease terminates, if an Excess is present, Tenant shall promptly pay to Landlord such amount. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term. 

4.4.2 Statement of Estimated Building Direct Expenses. In addition, Landlord shall 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 Building Direct Expenses for the then-current Expense Year
shall be and the estimated excess (the “Estimated Excess”) as calculated by comparing the Building Direct Expenses for such Expense Year, which shall be based upon the Estimate, to the amount of Building Direct Expenses for the Base
Year. 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 Excess under this Article 4, nor shall Landlord be prohibited from revising
any Estimate Statement or Estimated Excess theretofore delivered to the extent necessary. Thereafter, Tenant shall pay, with its next installment of Base Rent due, a fraction of the Estimated Excess 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 Excess set forth in the previous Estimate Statement delivered by Landlord to Tenant. 
 4.5 Taxes and
Other Charges for Which Tenant Is Directly Responsible. 
 4.5.1 Tenant shall be liable for and shall pay
thirty (30) 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 

  
 -17-

 
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
promptly following Landlord’s 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. 

4.5.2 If the tenant improvements installed in the Premises by or for the benefit of Tenant, whether installed and/or paid
for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which tenant improvements conforming to Landlord’s
“building standard” in other space in the Building are assessed, then the Tax Expenses levied against Landlord or the property by reason of such excess assessed valuation shall be deemed to be taxes levied against personal property
of Tenant and shall be governed by the provisions of Section 4.5.1, above. 
 4.5.3 Notwithstanding any
contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax or sales tax, service tax, transfer tax or value added tax, business tax or any other applicable tax on the rent or services herein or otherwise respecting this
Lease, (ii) taxes assessed upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project, including the Project parking
facility; or (iii) taxes assessed upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises. 
 ARTICLE 5

5.2 Prohibited Uses. Tenant further covenants and agrees that Tenant shall not use, or suffer or permit any person or
persons to use, the Premises or any part thereof for any use or purpose contrary to the provisions of the Rules and Regulations set forth in Exhibit D, attached hereto, or in violation of the laws of the United States of America, the
State of California, or the ordinances, regulations or requirements of the local municipal or county governing body or other lawful authorities having jurisdiction over the Project, including, without limitation, any such laws, ordinances,
regulations or requirements relating to hazardous materials or substances, as those terms are defined by applicable laws now or hereafter in effect. Tenant shall not do or permit anything to be done in or about the Premises which will in any way
damage the reputation of the Project or obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or unreasonably 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

  
 -18-

 
Premises shall be subject and subordinate to, all recorded easements, covenants, conditions, and restrictions now or hereafter affecting the Project. Tenant shall not cause or permit any
“Hazardous Substance,” as that term is defined below, to be kept, maintained, used, stored, produced, generated or disposed of (into the sewage or waste disposal system or otherwise) on or in the Premises by Tenant or Tenant’s agents,
employees, contractors, invitees, assignees or sublessees, without first obtaining Landlord’s written consent; provided that Tenant may use and store within the Premises normal and customary office and cleaning supplies that may contain
Hazardous Substances, in normal and customary amounts, provided that such office and cleaning supplies are stored in their original containers and are used and disposed of in accordance with all applicable laws and regulations pertaining thereto.
Tenant shall immediately notify, and shall direct Tenant’s agents, employees contractors, invitees, assignees and sublessees to immediately notify, Landlord of any incident in, on or about the Premises, the Building or the Project that would
require the filing of a notice under any federal, state, local or quasi-governmental law (whether under common law, statute or otherwise), ordinance, decree, code, ruling, award, rule, regulation or guidance document now or hereafter enacted or
promulgated, as amended from time to time, in any way relating to or regulating any Hazardous Substance. As used herein, “Hazardous Substance” means any substance which is toxic, ignitable, reactive, or corrosive and which is
regulated by any local government, the State of California, or the United States government. “Hazardous Substance” includes any and all material or substances which are defined as “hazardous waste,” “extremely hazardous
waste” or a “hazardous substance” pursuant to state, federal or local governmental law. “Hazardous Substance” also includes asbestos, polychlorobiphenyls (i.e., PCB’s) and petroleum. 

5.3 Landlord’s Representation. Landlord represents the following as of the delivery of the Premises to Tenant:

 5.3.1 Landlord has received no notice that any Hazardous Substance condition at, on, under, about, or
otherwise affecting the Premises or the Project violates any applicable law or regulation. 
 ARTICLE 6

 6.1.7 Subject to the provisions of Articles 11
(Damage and Destruction) and 13 (Condemnation) hereof and except for damage caused by any act or omission of Tenant or Tenant’s employees, agents, contractors or invitees, Landlord, as part of Operating Expenses, shall maintain the Common Areas
in good order, condition and repair and shall keep the foundation, (including slabs and slab repairs, crack filling and joint repairs), roof, building systems, structural supports and exterior walls, windows and doors of the improvements on the
Project in good order, condition and repair. Landlord shall not be obligated to maintain or repair interior windows, doors or plate glass. Tenant shall promptly report in writing to Landlord any defective condition known to it which Landlord under
the terms of this Lease is required to maintain or repair. 
 6.2 Overstandard Tenant Use. Tenant shall not,
without Landlord’s prior written consent, use heat-generating machines, machines other than normal fractional horsepower office machines, or equipment or lighting other than Building standard lights in the Premises, which may affect the
temperature otherwise maintained by the air conditioning system or increase the water normally furnished for the Premises by Landlord pursuant to the terms of Section 6.1 of this Lease, If Tenant uses water, electricity, heat or air
conditioning in excess of that supplied by Landlord pursuant to Section 6.1 of this Lease, Tenant shall pay to Landlord, upon billing, the cost of such excess consumption, the cost of the installation, operation, and maintenance of equipment
which is installed in order to supply such excess consumption, and the cost of the increased wear and tear on existing equipment caused by such excess consumption; and

consent of Landlord. If Tenant desires to use heat, ventilation or air conditioning during hours other than those for which Landlord is obligated to supply such utilities pursuant to the terms of Section 6.1 of this Lease, Tenant shall give
Landlord such prior notice, if any, as Landlord shall from time to time establish as appropriate, of Tenant’s desired use in order to supply such utilities, and Landlord shall supply such utilities to Tenant at such hourly cost to Tenant (which
shall be treated as Additional Rent) as Landlord shall from time to time establish. 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, promptly upon being billed for same. 
 6.3 Interruption
of Use. Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent 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 beyond
Landlord’s reasonable control; 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 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. 
 Notwithstanding the foregoing, in the event of any failure to furnish any such service, which is caused by the negligence or willful misconduct of Landlord, its employees, agents or contractors, then
Tenant shall give Landlord notice of such failure to furnish any such service, and if such failure to furnish any service continues for seven (7) consecutive business days after Landlord’s receipt of any such notice (the “Eligibility
Period”), 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. Such right to abate Base Rent and Tenant’s Share of Direct Expenses shall be Tenant’s sole and exclusive remedy at law 

  
 -21-

 
or in equity for any failure to furnish any service which is caused by the negligence or willful misconduct of Landlord, its employees, agents or contractors. Except as provided in this
Section 6.3, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder. 

ARTICLE 7 

REPAIRS 
 Tenant shall, at Tenant’s own expense, keep the Premises, including all improvements, fixtures and furnishings therein, and the floor and floor coverings 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 and damage by casualty or beyond
the reasonable control of Tenant; provided however, that, Landlord shall have the exclusive right, at Landlord’s option, but not the obligation, and upon reasonable notice to Tenant, to make such repairs and replacements, and Tenant shall pay
to Landlord the cost thereof, including Landlord’s standard fee for its involvement with such repairs and replacements, promptly upon being billed for same. Landlord and Tenant hereby agree that Landlord’s standard fee shall be equal to
ten percent (10%) of the first one hundred thousand dollars ($100,000.00) of costs and five percent (5%) of all costs in excess of that amount. 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 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. 
 ARTICLE 8 
 ADDITIONS AND ALTERATIONS 
 8.1 Landlord’s Consent to
Alterations. Tenant may not make or suffer to be made 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 in accordance with the terms and conditions of this Article 8, and which consent shall not
be unreasonably withheld, conditioned or delayed 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. 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. In the event that Tenant desires to determine whether or not it shall be responsible for removing any Alteration it 

  
 -22-

 
proposes to construct or have constructed in the Premises, Tenant shall send a Notice in writing to Landlord, at the time it requests Landlord’s consent to any Alteration, requesting that
Landlord inform it whether or not Tenant will have the responsibility for removing the proposed Alteration upon the expiration or earlier termination of the Lease Term and restoring the Premise to the condition existing prior to the installation of
the Alteration, normal wear and tear and damage from casualty excepted. In the event that Landlord responds to Tenant in writing in the affirmative, or fails to respond to Tenant within ten (10) days following Landlord’s receipt of
Tenant’s Notice, it shall be deemed that Tenant shall have the obligation to remove the proposed Alteration upon the expiration or earlier termination of the Lease Term and to restore the Premise to the condition existing prior to the
installation of the Alteration, normal wear and tear and damage from casualty excepted. In the event that Tenant fails to timely request that Landlord notify it whether or not the Tenant shall have the obligation to remove the proposed Alteration
upon the expiration or earlier termination of the Lease Term, Landlord may make such determination at the end of the Lease Term. 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. Notwithstanding the foregoing, Tenant shall be permitted to make alterations to the Premises throughout the Lease Term which (i) do not affect the Base Building (including, without limitation, any structural
elements of the Building) and (ii) do not affect any Base Building systems (including, without limitation, any mechanical, plumbing, electrical or HVAC systems serving the Building), and (iii) are not visible from the exterior of the
Premises, and (iv) do not require a building permit or other governmental approvals, without Landlord’s prior written consent (hereinafter, “Tenant’s Alterations”), in accordance with the terms and provisions of
Section 8.6, below. 
 8.2 Manner of Construction. Landlord shall have the exclusive right, at
Landlord’s option, but not the obligation, to make the Alterations at Tenant’s sole cost and expense. Prior to the commencement of construction of any Alterations or repairs, Tenant shall submit to Landlord, for Landlord’s review and
approval in its reasonable discretion, all plans, specifications and working drawings relating thereto. Tenant, at its sole cost and expense, shall retain an architect/space planner selected by Tenant, and reasonably approved by Landlord, to prepare
such plans, specifications and working drawings; provided that, Tenant shall also retain the engineering consultants designated by Landlord to prepare all plans and engineering working drawings, if any, relating to the structural, mechanical,
electrical, plumbing, HVAC, lifesafety and sprinkler work of the Alterations. Tenant shall cause each architect/space planner and engineer retained by Tenant to follow Landlord’s standard construction administration procedures and to utilize
the standard specifications and details for the Building, all as promulgated in writing by Landlord from time to time. Tenant and Tenant’s architect/space planner shall verify, in the field, the dimensions and conditions as shown on the
relevant portions of the “Base Building” plans, and Tenant and Tenant’s architect/space planner shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith, In addition, at
Landlord’s option, Landlord may submit Tenant’s plans, specifications and working drawings to a third-party architect and/or engineer, selected by Landlord, for their review, at Tenant’s sole cost and expense. Landlord’s review
of plans, specifications and working drawings as set forth in this Section 8.2, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, compliance with
applicable building codes or other like matters. Accordingly, notwithstanding that any plans, specifications or working drawings are reviewed by Landlord or its space planner, architect, 

  
 -23-

 
engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space planner, architect, engineers, and consultants,
Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the plans, specifications and working drawings for the Alterations, and Tenant’s waiver and indemnity set
forth in Section 10.1 of this Lease, below, shall specifically apply to the plans, specifications and working drawings for the Alterations. Following Landlord’s approval in its reasonable discretion of all plans, specifications and working
drawings for the Alterations, a contractor to construct the Alterations shall be selected by Tenant from the list of contractors approved by Landlord. Landlord shall provide to Tenant an itemized statement of costs, as set forth in the proposed
contract with such contractor. Tenant shall approve and deliver to Landlord the itemized statement of costs provided to Tenant in accordance with this Section 8.2, and upon receipt of such itemized statement of costs by Landlord, Landlord shall
be released by Tenant (i) to retain the contractor who submitted such itemized statement of costs, and (ii) to purchase the items set forth in such itemized statement of costs and to commence the construction relating to such items.
Landlord hereby assigns to Tenant all warranties and guaranties by the contractor selected in accordance with this Section 8.2 to construct the Alterations, and Tenant hereby waives all claims against Landlord relating to, or arising out of the
construction of, the Alterations. In the event Tenant requests any Alterations in the Premises which require or give rise to governmentally required changes to the “Base Building,” as that term is defined below, then Landlord shall, at
Tenant’s expense, make such changes to the Base Building. As used in this Lease, the “Base Building” shall include the structural portions of the Building, and the public restrooms, elevators, exit stairwells and the systems
and equipment located in the internal core of the Building on the floor or floors on which the Premises are located. In performing the work of any Alterations for which Tenant is responsible, Tenant shall have the work performed in such manner so as
not to obstruct access to the Project or any portion thereof, by any other tenant of the Project, and so as not to obstruct the business of Landlord or other tenants in the Project. 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. 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 in which the
Project is located 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 in CAD format as well as all permits, approvals and other documents issued by any governmental agency in connection with the Alterations. 
 8.3 Payment for Improvements. Tenant shall pay to Landlord, within ten (10) business days after being billed for the same, all costs related to the construction of the Alterations,
including, without limitation, the following items and costs: (i) all amounts actually paid by Landlord to any architect/space planner, engineer, consultant, contractor, subcontractor, mechanic, materialman or other person, whether retained by
Landlord or Tenant, in connection with the Alterations, and all fees incurred by, and the actual cost of documents and materials supplied by, Landlord and Landlord’s consultants in connection with the preparation and review of all plans,
specifications and working drawings for the Alterations; (ii) all plan check, permit and license fees relating to construction of the Alterations paid by Landlord; (iii) the cost of any

  
 -24-

 
changes in the Base Building when such changes are required by any plans, specifications or working drawings for the Alterations (including if such changes are due to the fact that such work is
prepared on an unoccupied basis), such cost to include all direct architectural and/or engineering fees and expenses incurred by Landlord in connection therewith; (iv) the cost of any changes to the plans, specifications and working drawings
for the Alterations or to the Alterations themselves required by all applicable zoning and building codes and other laws and paid by Landlord; (v) sales and use taxes and Title 24 fees imposed on, assessed against or paid by Landlord;
(vi) Landlord’s standard fee for its involvement with such Alterations; and (vii) all other costs incurred by Landlord in connection with the construction of the Alterations. Landlord, at its option, may render bills to Tenant in
advance of, or during, construction of the Alterations so as to enable Landlord to pay all costs and expenses incurred by Landlord in connection with the Alterations (including, without limitation, costs of the contractor retained to construct the
Alterations) without advancing Landlord’s own funds. At Landlord’s election in its sole and absolute discretion, Tenant shall deliver to Landlord prior to commencement of construction of the Alterations cash in an amount equal to all
estimated costs related to the construction of such Alterations, or such lesser amount as Landlord shall specify, to be held by Landlord and disbursed by Landlord for costs related to the construction of the Alterations as such costs are incurred.
In the event that, after Tenant’s approval of a cost proposal for the Alterations in accordance with Section 8.2, above, any revisions, changes or substitutions shall be made to the plans, specifications and working drawings or the
Alterations, any additional costs which arise in connection with such revisions, changes or substitutions or any other additional costs shall be paid by Tenant to Landlord promptly upon Landlord’s written request. Any surplus funds delivered by
Tenant and held by Landlord in connection with the Alterations shall be refunded to Tenant when the all costs related to the construction of the Alterations have been paid in full. 

8.4 Construction Insurance. In addition to the requirements of Article 10 of this Lease, in the event that any Alterations
are made pursuant to this Article 8, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant carries “Builder’s All Risk” insurance in an amount reasonably 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, Landlord may, in its discretion, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such
Alterations and naming Landlord as a co-obligee. 
 8.5 Landlord’s Property. All Alterations, improvements,
fixtures, 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; provided, however, Landlord may, Landlord may,
(i) by written notice to Tenant or otherwise as specified in Section 8.1, above, or (ii) in the case of Tenant’s Alterations, by the procedure specified in Section 8.6.5, below, or (iii) given within a reasonable time
following any earlier termination of this Lease, require Tenant, at Tenant’s expense, to remove any Alterations or improvements and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the
Premises to their condition existing prior to the installment of such Alterations or improvements or, at Landlord’s election, to a building standard tenant improved 

  
 -25-

 
condition as determined by Landlord. If Tenant fails to complete such removal and/or to repair any damage caused by the removal of any Alterations or improvements in the Premises and return the
affected portion of the Premises to their condition existing prior to the installment of such Alterations or improvements or, if elected by Landlord, to a building standard tenant improved condition as determined by Landlord, prior to the expiration
or earlier termination of this Lease, then Rent shall continue to accrue under this Lease in accordance with Article 16, below, after the end of the Lease Term until such work shall be completed, and Landlord shall have the right, but not the
obligation, to perform such work and to 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, except and to
the extent caused by the negligence or willful misconduct by Landlord, its employees, agents or contractors, for which Tenant shall not be responsible. 
 8.6 Tenant’s Alterations. Notwithstanding the foregoing, Tenant shall be permitted to make Tenant’s Alterations to the Premises throughout the Lease Term which (i) do not
affect the Base Building (including, without limitation, any structural elements of the Building) and (ii) do not affect any Base Building systems (including, without limitation, any mechanical, plumbing, electrical or HVAC systems serving the
Building) and (iii) are not visible from the exterior of the Premises, and (iv) do not require a building permit or other governmental approvals, without Landlord’s prior written approval, provided the following provisions are met:

 8.6.1 All such Tenant’s Alterations to the Premises shall be paid for solely by Tenant, and shall not
exceed in cost, in the aggregate, Forty Thousand Dollars ($40,000.00) over the Lease Term without Landlord’s prior written approval. 
 8.6.2 The general contractor to construct Tenant’s Alterations shall be selected by Tenant and approved by Landlord, such approval not to be unreasonably withheld or delayed; provided that such
general contractor shall be a California licensed general contractor with experience in constructing improvements similar to the Tenant’s Alterations in office buildings similar to the Building, and shall carry the insurance specified in
Section 8.4. Tenant shall provide Landlord with a certificate of insurance prior to commencing any such Tenant’s Alterations. 
 8.6.3 Tenant shall provide Landlord with not less than twenty (20) days prior written notice of the commencement of such Tenant’s Alterations so that Landlord may post notices of
non-responsibility with respect to such Tenant’s Alterations; 
 8.6.4 All such Tenant’s Alterations
shall be constructed in accordance with the plans and specifications therefore and in conformance with all applicable building codes and other laws, rules, and regulations pertaining thereto. Tenant, its general contractor and all subcontractors
shall comply with all reasonable rules and regulations imposed by Landlord in connection with any Tenant’s Alterations. Tenant shall have the Tenant’s Alterations performed in such manner so as not to obstruct access to the Building or any
portion thereof, or any other 

  
 -26-

 
tenant of the Building, and so as not to obstruct the business of Landlord or other tenants in the Building. 

8.6.5 Tenant shall send a Notice (the “Removal Notice”) in writing to Landlord, at least sixty (60) days
prior to the expiration of the Lease Term, requesting that Landlord inform it whether or not Tenant will have the responsibility for removing any Tenant Alterations upon the expiration or earlier termination of the Lease Term and for restoring the
Premise to the condition existing prior to the installation of any Tenant Alterations, normal wear and tear and damage from casualty excepted. In the event that Landlord responds to Tenant in writing in the affirmative, or fails to respond to Tenant
within ten (10) business days following Landlord’s receipt of the Removal Notice, it shall be deemed that Tenant shall have the obligation at its sole cost and expense for removing the Tenant Alterations upon the expiration or earlier
termination of the Lease Term and for restoring the Premise to the condition existing prior to the installation of the Tenant Alterations, normal wear and tear and damage from casualty excepted. Once Tenant has determined whether or not it has the
obligation to restore any Tenant Alterations, Tenant shall, as soon as reasonably possible, but in no event less than thirty (30) days prior to expiration of the Lease Term, commence such removal of the Tenant’s Alterations and the
restoration of the Premises to the condition existing prior to the making of Tenant’s Alterations, normal wear and tear and damage from casualty excepted. 
 8.6.6 In the event that Tenant shall fail to timely send Landlord a Removal Notice, Landlord, at its option, may elect to require Tenant, at its sole cost and expense, to remove (i) those Alterations
which Tenant failed to request that Landlord notify it at the time of approval whether or not Tenant would have the obligation to remove upon the expiration or earlier termination of the Lease Term, and (iii) the Tenant Alterations, and to
restore the Premises to the condition existing prior to the installation of the Alterations and/or Tenant Alterations, normal wear and tear and damage from casualty excepted. If Tenant fails to complete such removal obligations and/or to repair any
damage caused by the removal of any Alterations and/or Tenant Alterations in the Premises and return the affected portion of the Premises to their condition existing prior to the installment of such Alterations and/or Tenant Alterations prior to the
expiration or earlier termination of this Lease, then Rent shall continue to accrue under this Lease in accordance with Article 16 below, after the end of the Lease Term until such work shall be completed, and Landlord shall have the right, but not
the obligation, to perform such work and to charge the cost thereof to Tenant, including Landlord’s standard fee for performing such work. 
 8.6.7 Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of San Mateo County in accordance with Section 3093 of the Civil Code of the State of California or
any successor statute. 
 ARTICLE 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,

  
 -27-

 
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 twenty (20) 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. Tenant shall remove any such lien or encumbrance by bond or otherwise within five (5) 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. The amount so paid shall be deemed Additional Rent under this Lease payable promptly following Landlord’s written demand, without limitation as to other remedies
available to Landlord under this Lease. Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord’s title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or
express or implied contract. Any claim to a lien or encumbrance upon the Building or Premises arising in connection with any such work or respecting the Premises not performed by or at the request of Landlord shall be null and void, or at
Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be subordinate to Landlord’s title to the Project, Building and Premises. 

ARTICLE 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 (including, but not
limited to, any personal injuries resulting from a slip and fall in, upon or about the Premises) and agrees that Landlord, its partners, subpartners and their respective officers, agents, employees, 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 any person in, upon or
about the Premises or by Tenant or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all loss, cost, damage, 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 (including, but not limited to, a slip and fall), any acts, omissions or negligence of Tenant or of the contractors,
agents, employees, invitees, guests or licensees of Tenant or any such person, in, on or about the Building or the Project parking areas or any breach of the terms of this Lease by Tenant, either prior to the Lease Term, during any pre-Lease Term
possession by Tenant, as contemplated by Section 2.3, above, or during or after the expiration of the Lease Term, provided that the terms of the foregoing indemnity shall not apply to the negligence or willful misconduct of Landlord or
Landlord’s agents, employees, and contractors (subject to the provisions of Section 10.5 below). 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 actual professional fees such as reasonable appraisers’, accountants’ and attorneys’ fees, except and to the extent
that it is ultimately determined that the claim that is the subject of the lawsuit arises from or is related to the negligence or willful misconduct of Landlord or Landlord’s agents, employees, or contractors. The provisions of this
Section 10.1 shall survive the 

  
 -28-

 
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. 

10.2 Tenant’s Compliance With Landlord’s Fire and Casualty Insurance. Tenant shall, at Tenant’s expense,
comply with all insurance company requirements pertaining to the use of the Premises. Tenant shall not cause or permit anything to be done in, upon or about the Premises which would in any way increase the premium for, cause the cancellation of or
otherwise affect any insurance carried by Landlord in connection with the Project or any part thereof, or cause a cancellation of any insurance policy covering the Building or any part thereof. Without limiting Landlord’s remedies for
Tenant’s breach of the foregoing covenant, 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 promptly upon being billed
therefor. 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 any similar body of which Landlord provides
notice to Tenant. 
 10.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the following
amounts. 
 10.3.1 Commercial General Liability Insurance covering the insured against claims of bodily injury,
personal injury and property damage (including loss of use thereof) arising out of Tenant’s operations, and contractual liabilities (covering the performance by Tenant of its indemnity agreements) including a Broad Form endorsement covering the
insuring provisions of this Lease and the performance by Tenant of the indemnity agreements set forth in Section 10.1 of this Lease, for limits of liability not less than: 

 

			
	Bodily Injury and	  	$5,000,000 each occurrence
	Properly Damage Liability	  	$5,000,000 annual aggregate
		
	Personal Injury Liability	  	$5,000,000 each occurrence
		  	$5,000,000 annual aggregate
		  	0% Insured’s participation

 10.3.2 Landlord agrees that Tenant may provide umbrella or excess liability insurance to
so achieve the above minimum liability limits, provided that the policy coverages are absolutely concurrent. 

10.3.3 Physical Damage Insurance covering (i) all office furniture, business and trade fixtures, office equipment,
free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant, (ii) the “Tenant Improvements,” as that term is defined in the
Tenant Work Letter, and the other improvements which exist in the Premises as of the Rent Commencement Date (excluding the Base Building, which for the purposes of Tenant’s insurance coverage shall mean the basic shell of the Premises, which
shall include only the four exterior demising walls of the Premises, including the studs for such demising walls, but not including any sheetrock on such demising walls, and not including any interior demising walls, any interior improvements, and

  
 -29-

 
any interior distribution of Building services, including HVAC service, plumbing or electrical service) (the “Original Improvements”), and (iii) all other improvements,
alterations and additions to the Premises. Such insurance shall be written on an Special Causes of Loss form or damage basis, for the full replacement cost value (subject to reasonable deductible amounts) new without deduction for 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, and providing business interruption coverage for a period of one year. 

10.3.4 Worker’s Compensation and Employer’s Liability or other similar insurance pursuant to all applicable
state and local statutes and regulations. 
 10.4 Form of Policies. The minimum limits of policies of insurance
required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall (i) name Landlord, and any other party the Landlord so specifies, as an additional insured, including Landlord’s
managing agent, if any; (ii) specifically cover the liability assumed by Tenant under this Lease, including, but not limited to, Tenant’s obligations under Section 10.1 of this Lease; (iii) be issued by an insurance company
having a rating of not less than A-VIII 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 requirement 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 ten (10) days’ prior written notice shall have been given to Landlord and any mortgagee of Landlord. 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 certificates, Landlord may, at its option, procure such policies for the
account of Tenant, and the cost thereof shall be paid to Landlord within five (5) business days after delivery to Tenant of bills therefor. 
 10.5 Subrogation. Landlord and Tenant intend that their respective property loss risks shall be borne by reasonable insurance carriers to the extent above provided, and Landlord and Tenant
hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property 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 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 are now, or shall be, endorsed such that the waiver of subrogation shall not affect the right of the insured to recover thereunder, so long as no material additional premium is charged therefor. 

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 in a manner comparable to other 

  
 -30-

 
comparable Class A office buildings in the San Francisco Bay Area. In addition, except as otherwise set forth in Article 8 hereof, Tenant shall cause its contractors and vendors,
prior to entering onto the Premises to perform any work therein, to carry Commercial General Liability Insurance in the amount set forth in Section 10.3.1, above, and to name Landlord, and any other party the Landlord reasonably specifies, as
an additional insured, including Landlord’s managing agent, if any, on such insurance policy. 
 ARTICLE 11 

 DAMAGE AND DESTRUCTION 
 11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty. If the Premises or any Common
Areas 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, the Common Area parking areas and any common restrooms serving 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 items (ii) and (iii) of
Section 10.3,2 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, 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 (and further provided that, in the event such insurance proceeds are inadequate to fully restore the Premises to its original condition, Tenant shall have the right to request,
subject to Landlord’s approval, that the Premises be restored to a lesser condition, but in no event less than a Building standard condition, provided that the insurance proceeds are sufficient to restore the Premises to a Building standard
condition). In the event that the reason that the insurance proceeds are inadequate to restore the Premises is that Tenant has failed to fully insure the Tenant Improvements and Original Improvements, as well as any Alterations and Tenant
Alterations, for their full replacement value (subject to commercially reasonable deductibles), Landlord may disapprove Tenant’s request to restore the Premises to a lesser condition, and Tenant, at its sole cost and expense, shall fund the
difference between any insurance proceeds and the full cost of restoring the Premises, including, without limitation, any necessary insurance deductibles. 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, and in the event that this Lease does not terminate pursuant to Section 11.2 below, or for any other reason, Tenant shall, at its sole cost and expense, repair any injury
or damage to the Tenant Improvements and the Original 

  
 -31-

 
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. 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 a portion thereof or Common Areas necessary to Tenant’s occupancy, and the Premises or a portion thereof are not occupied by Tenant as a result thereof, then during the time and to the extent
the Premises are not occupied by Tenant as a result thereof, the Rent shall be abated from the date of the casualty in proportion to the ratio that the amount of rentable square feet of the Premises which is not occupied by Tenant as a result
thereof, 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 or that portion of the proceeds from Landlord’s insurance policies allocable to the Building or the Project, as the case may be; (iv) Landlord decides
to rebuild the Building or Common Areas so that they will be substantially different structurally or architecturally; (v)the damage occurs during the last twelve (12) months of the Lease Term; or (vi) 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. In the event this Lease is terminated in accordance with the terms of this Section 11.2, or is terminated by tenant pursuant to
Section 11.1, above, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under items (ii) and (iii) of Section 10.3.2 of this
Lease. Notwithstanding anything to the contrary contained herein, Tenant may elect to terminate this Lease upon written Notice to Landlord if damage to or destruction of the Premises occurs during the last twelve (12) months of the Lease Term,
and the period of time it would take to repair such damage to or destruction of the Premises is reasonably estimated by Tenant to exceed one hundred twenty (120) days. 

  
 -32-

 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. 

ARTICLE 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. 
 ARTICLE 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. If more than twenty-five
percent (25%) of the rentable square feet of the Premises is taken, or if all reasonable access to the Premises is substantially impaired, in each case for a 

  
 -33-

 
period in excess of one hundred eighty (180) days, Tenant 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, 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, 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 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. 
 ARTICLE 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 individually as a “Transfer,” and, 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, including all existing operative documents to be executed to evidence such Transfer or the agreements incidental or related to such
Transfer, provided that Landlord shall have the right to require Tenant to utilize Landlord’s standard Transfer documents in connection with the documentation of such Transfer, (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 required by Landlord which will 

  
 -34-

 
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,
and (v) an executed estoppel certificate from Tenant in the form attached hereto as Exhibit E. 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 review and processing fees, as well as any reasonable professional fees
(including, without limitation, attorneys’, accountants’, architects’, engineers’ and consultants’ fees) incurred by Landlord, 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, or would be a significantly less prestigious
occupant of the Building than Tenant; 
 14.2.2 The Transferee intends to use the Subject Space for purposes
which are not permitted under this Lease; 
 14.2.3 The Transferee is either a governmental agency or
instrumentality thereof; 
 14.2.4 The 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; 
 14.2.5 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; 

14.2.6 Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by,
or is under common control with, the proposed Transferee, (i) occupies space in the Project at the time of the request for consent, or (ii) is negotiating or has negotiated with Landlord to lease space in the Project; 

14.2.7 In Landlord’s reasonable judgment, the use of the Premises by the proposed Transferee would not be comparable
to the types of office use by other tenants in the Project, would entail any alterations which would lessen the value of the tenant improvements in the Premises, would result in more than a reasonable density of occupants per square foot of the
Premises, would increase the burden on elevators or other Building systems or equipment over the burden thereon prior to the proposed Transfer, or would require increased services by Landlord; or 

14.2.8 The proposed Transfer is of less than fifty percent (50%) of the entire Premises and for less than the then
remaining Lease Term. 

  
 -35-

 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 (i) such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the proposed
Transfer to be more favorable to the Transferee than the terms set forth in Tenant’s original Transfer Notice, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s
right of recapture, if any, under Section 14.4 of this Lease). 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 declaratory judgment and an injunction for the relief sought, and Tenant hereby waives the provisions of Section 1995.310 of
the California Civil Code, or any successor statute, and 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. Tenant shall indemnify, defend and hold harmless Landlord from any and all liability, losses, claims, damages, costs, expenses, causes of action and proceedings involving any third party or parties (including without
limitation Tenant’s proposed subtenant or assignee) who claim they were damaged by Landlord’s wrongful withholding or conditioning of Landlord’s consent. 
 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 Seventy-Five percent
(75%) 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, 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.
“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. Tenant shall make a determination of the amount of Landlord’s applicable share of
the Transfer Premium on a monthly basis as rent or other consideration is paid by Transferee to Tenant under the Transfer. In the calculations of the Rent (as it relates to the Transfer Premium calculated under this Section 14.3), and the
Transferee’s Rent under Section 14.2, above, the Rent paid for the Subject Space by Tenant, and the Transferee’s Rent, shall be computed after adjusting such rent to the actual effective rent to be paid, taking into consideration any
and all leasehold concessions granted in connection therewith, including, but not limited to, any rent credit and tenant improvement allowance. For purposes of calculating any such effective rent all such concessions shall be amortized on a
straight-line basis over the relevant term. 
 14.4 Landlord’s Option as to Subject Space. Notwithstanding
anything to the contrary contained in this Article 14, Landlord shall have the option, by giving written notice to 

  
 -36-

 
Tenant within thirty (30) days after receipt of any Transfer Notice, to (i) recapture the Subject Space, or (ii) take an assignment or sublease of the Subject Space from Tenant,
Such recapture or sublease or assignment notice, shall cancel and terminate this Lease, or create a sublease or assignment, as the case may be, with respect to the Subject Space as of the date stated in the Transfer Notice as the effective date of
the proposed Transfer. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, then (i) 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; (ii) 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; and (iii) Landlord shall construct or cause to be constructed a demising wall separating that portion of the Premises recaptured by Landlord from that portion of the Premises retained by Tenant; provided that,
Tenant hereby agrees that, notwithstanding Tenant’s occupancy of its retained portion of the Premises during the construction of such demising wall by Landlord, Landlord shall be permitted to construct such demising wall during normal business
hours, without any obligation to pay overtime or other premiums, and the construction of such demising wall by Landlord shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of Rent, and Landlord shall have
no responsibility or for any reason be liable to Tenant for any direct or indirect injury to or interference with Tenant’s business arising from the construction of such demising wall, nor shall Tenant be entitled to any compensation or damages
from Landlord for loss of the use of the whole or any part of its retained portion of the Premises or of Tenant’s personal property or improvements resulting from the construction of such demising wall, or for any inconvenience or annoyance
occasioned by the construction of such demising wall; and provided further that, Tenant shall be responsible for, and shall pay to Landlord promptly upon being billed therefor, fifty percent (50%) of all costs related to the construction of
such demising wall, including Landlord’s standard fee for its involvement with such demising wall. If Landlord declines, or fails to elect in a timely manner, to recapture, sublease or take an assignment of the Subject Space under this
Section 14.4, then, provided Landlord has consented to the proposed Transfer, Tenant shall be entitled to proceed to transfer the Subject Space to the proposed Transferee, subject to provisions of this Article 14. 

14.5 Effect of Transfer. If Landlord consents to a Transfer, then (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 and content reasonably acceptable to Landlord, including, without limitation, at Landlord’s option, a “Transfer Agreement,” as that term is defined in this
Section 14.5, below; (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, and, in the event of a Transfer of Tenant’s entire interest in this Lease, the liability of Tenant and such
Transferee shall be joint and several. 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 

  
 -37-

 
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 three percent
(3%), Tenant shall pay Landlord’s costs of such audit. Notwithstanding anything to the contrary contained in this Article 14, Landlord, at its option in its sole and absolute discretion, may require, as a condition to the validity of any
Transfer, that both Tenant and such Transferee enter into a separate written agreement directly with Landlord (a “Transfer Agreement”), which Transfer Agreement, among other things, shall create privity of contract between Landlord
and such Transferee with respect to the provisions of this Article 14, and shall contain such terms and provisions as Landlord may reasonably require, including, without limitation, the following: (A) such Transferee’s agreement to be
bound by all the obligations of Tenant under this Lease (including, but not limited to, Tenant’s obligation to pay Rent), provided that, in the event of a Transfer of less than the entire Premises, the obligations to which such Transferee shall
agree to be so bound shall be prorated on a basis of the number of rentable square feet of the Subject Space in proportion to the number of square feet in the Premises; (B) such Transferee’s acknowledgment of, and agreement that such
Transfer shall be subordinate and subject to, Landlord’s rights under Section 19.3 of this Lease; and (C) Tenant’s and such Transferee’s recognition of and agreement to be bound by all the terms and provisions of this
Article 14, including, but not limited to, any such terms and provisions which Landlord, at its option, requires to be expressly set forth in such Transfer Agreement. Upon the occurrence of any default by Transferee under such Transfer, Landlord
shall have the right, at its option, but not the obligation, on behalf of Tenant, to pursue any or all of the remedies available to Tenant under such Transfer or at law or in equity (all of which remedies shall be distinct, separate and cumulative).

 14.6 Occurrence of Default. Any Transfer hereunder, whether or not such Transferee shall have executed a
Transfer Agreement, shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, then Landlord shall have all of the rights set forth in Section 19.3 of this Lease with
respect to such Transfer. In addition, if Tenant shall be in uncured default under Article 19.1 of this Lease, then 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 a Transfer directly to Landlord (which payments 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. 
 14.7 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%)

  
 -38-

 
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 (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. 

14.8 Permitted Transfers. Notwithstanding anything contained to the contrary herein, Original Tenant only may assign this
Lease or sublet all or a portion of the Premises to its “Parent” or to any “Subsidiary” or “Affiliate” or “Successor” (as hereinafter defined) without obtaining the prior written consent of Landlord, provided
that the following conditions are met: 
 (i) Tenant is not in default under the Article 19.1 of this Lease at
the time of the assignment; 
 (ii) any assignee shall assume and be bound by ail the conditions, obligations and
agreements contained in this Lease; 
 (iii) there shall be no change in the Permitted Use set forth in
Section 7 of the Summary; 
 (iv) Tenant shall not be released from liability under this Lease; and

 (v) In Landlord’s reasonable business judgment, the present tangible net worth of the Successor is equal
to or greater than Tenant’s net worth at the time this Lease was entered into or at the time of Tenant’s intended Transfer to a Successor. 
 As used herein: (i) “Affiliate” shall mean a corporation, limited liability company, partnership or other entity which (a) directly or indirectly controls Tenant, (b) is under the
direct or indirect control of Tenant, or (c) is under common direct or indirect control with Tenant; (ii) “control” shall mean voting control of the controlled entity; (iii) “Parent” shall mean an entity which owns
a majority of Tenant’s voting equity; (iv) “Subsidiary” shall mean an entity a majority of the voting equity of which is owned by Tenant; and (v) “Successor” shall mean a person or entity which acquires all or
substantially all of the assets and business operations of Tenant, including, without limitation, in connection with (x) a purchase of all or a controlling interest in the capital stock or other ownership interest in Tenant, or (y) a
merger or consolidation of Tenant. The foregoing shall be referred to as a “Permitted Transfer.” In addition, a sale or transfer of the capital stock, memberships or interests of Tenant shall be deemed a Permitted Transfer if (1) such
sale or transfer occurs in connection with any bona fide financing or capitalization for the benefit of Tenant, or (2) Tenant becomes a publicly traded corporation. Tenant shall give Landlord prior written notice of a Permitted Transfer
at least fifteen (15) days before the occurrence of a Permitted Transfer, and in the case of a Successor, or a sale or transfer of the capital stock, memberships or interests in connection with any bona fide financing or capitalization
for the benefit of Tenant, Tenant shall provide Landlord with evidence 

  
 -39-

 
of such Successor’s present tangible net worth, as well as the present tangible net worth of Tenant, including the present tangible net worth of Tenant following any such bona fide
financing or capitalization for the benefit of Tenant. Any Permitted Transferee which becomes the Tenant under this Lease shall assume in writing for the benefit of Landlord this Lease and all of Tenant’s obligations under this Lease, and
provided further, that in all such cases described above, after giving effect to any such transaction, the resulting Tenant under this Lease is not the ultimate parent company (e.g., it is a subsidiary of another company), then the resulting Tenant
(whether the original Tenant or a Permitted Transferee) shall furnish Landlord with a written assumption of Tenant’s obligations under this Lease by the ultimate parent company. Notwithstanding anything to the contrary contained in this Article
14, in no event shall Landlord be entitled to any Transfer Premium, as specified in Section 14.3, above, nor shall Landlord be entitled to exercise any recapture rights, or to take an assignment of the Premises, all as set forth in
Section 14.4, above, in connection with any Permitted Transfer. 
 ARTICLE 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 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, damage by casualty 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, such items of furniture, equipment, business and trade fixtures, free-standing 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. 

  
 -40-

 ARTICLE 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, and in such case Rent shall be payable at a monthly rate equal to one hundred fifty percent (150%) of the Rent applicable during the last rental period of the Lease Term under
this Lease for the first (1st) month of such hold
over tenancy, and two (2) times the Rent applicable during the last rental period of the Lease Term under this Lease for each month thereafter. Such month-to-month tenancy 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 upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including
reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord
resulting therefrom. 
 ARTICLE 17  
 ESTOPPEL CERTIFICATES 
 Within ten (10) days following a
request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit E, 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 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, 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. Any financial statements furnished to Landlord by Tenant shall be copies of financial statements regularly prepared in the ordinary course of business for the
most recent calendar year, and Landlord shall not require that Tenant absorb the expense of special financial statements not corresponding to its regular schedule for such documents, provided that such financial statements are certified by
Tenant’s chief financial officer as being true, complete and accurate or are audited financials statements or, 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 

  
 -41-

 
estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct,
without exception. 
 ARTICLE 18  
 MORTGAGE OR GROUND LEASE 
 18.1 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) 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. In the event that Landlord intends to finance or re-finance the Building or the Project in the
future, Landlord shall make a good faith effort to provide Tenant with a Subordination, Non- Disturbance and Attornment Agreement from the lender proposing to finance or re-finance the Building or the Project. 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. 
 18.2 Notice to Lienholder or Ground Lessor. Notwithstanding anything to the contrary contained in Article
28, below, or elsewhere in this Lease, upon receipt by Tenant of notice from any holder of a mortgage, trust deed or other encumbrance in force against the Building or the Project or any part thereof which includes the Premises or any lessor under a
ground lease or underlying lease of the Building or the Project, or from Landlord, which notice sets forth the address of such lienholder or ground lessor, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is
given to such lienholder or ground lessor at the appropriate address therefor (as specified in the above-described notice or at such other places as may be designated from time to time in a notice to Tenant in accordance with Article 28, below), and
the curing of any of Landlord’s defaults by such lienholder or ground lessor within a reasonable period of time after such notice from Tenant (including a reasonable 

  
 -42-

 
period of time to obtain possession of the Building or the Project, as the case may be, if such lienholder or ground lessor elects to do so) shall be treated as performance by Landlord. For the
purposes of this Article 18, the term “mortgage” shall include a mortgage on a leasehold interest of Landlord (but not a mortgage on Tenant’s leasehold interest hereunder). 

18.3 Assignment of Rents. With reference to any assignment by Landlord of Landlord’s interest in this Lease, or the
Rent payable to Landlord hereunder, conditional in nature or otherwise, which assignment is made to any holder of a mortgage, trust deed or other encumbrance in force against the Building or the Project or any part thereof which includes the
Premises or to any lessor under a ground lease or underlying lease of the Building or the Project, Tenant agrees as follows: 
 18.3.1 The execution of any such assignment by Landlord, and the acceptance thereof by such lienholder or ground lessor, shall never be treated as an assumption by such lienholder or ground lessor of any
of the obligations of Landlord under this Lease, unless such lienholder or ground lessor shall, by notice to Tenant, specifically otherwise elect. 
 18.3.2 Notwithstanding delivery to Tenant of the notice required by Section 18.3.1, above, such lienholder or ground lessor, respectively, shall be treated as having assumed Landlord’s
obligations under this Lease only upon such lienholder’s foreclosure of any such mortgage, trust deed or other encumbrance, or acceptance of a deed in lieu thereof, and taking of possession of the Building or the Project or applicable portion
thereof, or such ground lessor’s termination of any such ground lease or underlying leases and assumption of Landlord’s position hereunder, as the case may be. In no event shall such lienholder, ground lessor or any other successor to
Landlord’s interest in this Lease, as the case may be, be liable for any security deposit paid by Tenant to Landlord, unless and until such lienholder, ground lessor or other such successor, respectively, actually has been credited with or has
received for its own account as landlord the amount of such security deposit or any portion thereof (in which event the liability of such lienholder, ground lessor or other such successor, as the case may be, shall be limited to the amount actually
credited or received). 
 18.3.3 In no event shall the acquisition of title to the Building and the land upon
which the Building is located or the Project or any part thereof which includes the Premises by a purchaser which, simultaneously therewith, leases back to the seller thereof the entire Building or the land upon which the Building is located or the
Project or the entirety of that part thereof acquired by such purchaser, as the case may be, be treated as an assumption, by operation of law or otherwise, of Landlord’s obligations under this Lease, but Tenant shall look solely to such
seller-lessee, or to the successors to or assigns of such seller-lessee’s estate, for performance of Landlord’s obligations under this Lease. In any such event, this Lease shall be subject and subordinate to the lease to such
seller-lessee, and Tenant covenants and agrees in the event the lease to such seller-lessee is terminated to attorn, without any deductions or set-offs whatsoever, to such purchaser-lessor, if so requested to do so by such purchaser-lessor, and to
recognize such purchaser-lessor as the lessor under this Lease, provided such purchaser-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. For all purposes, such seller-lessee, or the successors to or assigns of such 

  
 -43-

 
seller-lessee’s estate, shall be the lessor under this Lease unless and until such seller-lessee’s position shall have been assumed by such purchaser-lessor. 

ARTICLE 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; 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 of the Premises by Tenant; or 
 19.1.4 The failure by Tenant to observe or perform according
to the provisions of (i) Article 5.1, where such failure continues for more than seven (7) business days after notice from Landlord, (ii) Article 5.2, where such failure continues for more than three (3) business days after notice from Landlord,
(iii) Article 9, where such failure continues for more than five (5) business days after notice from Landlord, (iv) Article 10, where such failure continues for more than two (2) business days after notice from Landlord, (v) Article 14, where such
failure continues for more than five (5) business days after notice from Landlord, (vi) Article 17, where such failure continues for more than three (3) business days after notice from Landlord, (vii) Article 18, where such failure continues for
more than three (3) business days after notice from Landlord, and (viii) Article 21.3.2, where such failure continues for more than five (5) days after notice from Landlord. 
 The notice periods provided in this Section 19.1 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 

  
 -44-

 
other remedy which it may have for 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 in accordance with law, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following: 

(i) The worth at the time of award of any 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 Paragraphs 19.2.1.(i) and 19.2.1.(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 Paragraph 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 

  
 -45-

 
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. If Landlord elects to terminate this Lease on account of any default by Tenant under
Section 19.1 hereof beyond any applicable notice and cure periods, as set forth in this Article 19, then Landlord shall have the right, at Landlord’s option in its sole discretion, (i) to terminate any and all assignments, subleases,
licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises, in which event Landlord shall have the right to repossess such affected portions of the Premises by any lawful means, or
(ii) to succeed to Tenant’s interest in any or all such assignments, subleases, licenses, concessions or arrangements, in which event Landlord may require any assignees, sublessees, licensees or other parties thereunder to attorn to and
recognize Landlord as its assignor, sublessor, licensor, concessionaire or transferor thereunder. In the event of Landlord’s election to succeed to Tenant’s interest in any such assignments, 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. 
 ARTICLE 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. 
 ARTICLE 21  
 SECURITY DEPOSIT 

21.1 In General. Concurrent with Tenant’s execution of this Lease, Tenant shall provide security for the faithful
performance by Tenant of all of its obligations under this Lease. Tenant shall provide such security as a letter of credit pursuant to Section 21.3, below. 

  
 -46-

 21.2 Security Deposit. Concurrent with Tenant’s execution of this Lease,
Tenant shall deposit with Landlord a security deposit (the “Security Deposit”) in the amount set forth in Section 10 of the Summary, as security for the faithful performance by Tenant of all of its obligations under this Lease.
If Tenant is in uncured default under Article 19.1 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, promptly following Landlord’s written demand therefore, 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 and Landlord shall have the right to commingle the Security Deposit with Landlord’s other funds. Tenant hereby waives the provisions of
Section 1950.7 of the California Civil Code, or any successor statute. 
 21.3 Letter of Credit. 

21.3.1 Delivery of Letter of Credit. In lieu of a cash Security Deposit, Tenant shall deliver to Landlord
concurrent with Tenant’s execution of this Lease, an unconditional, clean, irrevocable letter of credit (hereinafter, the “L/C”) in the initial amount set forth in Section 10 of the Summary ($300,000,00), which L/C shall
be issued by a money-center bank (a bank which accepts deposits, maintains accounts, has a local San Francisco office which will negotiate a letter of credit, and whose deposits are insured by the FDIC) which is acceptable to Landlord. The L/C shall
be in the form attached hereto as Exhibit G or such other form as is acceptable to Landlord. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L/C. 

21.3.2 Application of Letter of Credit. The L/C shall be held by Landlord as security for the faithful performance
by Tenant of all of its obligations under this Lease. The L/C shall not be mortgaged, assigned or otherwise encumbered in any manner whatsoever by Tenant. If Tenant is in uncured default under Article 19.1 with respect to any of the provisions of
this Lease, including, but not limited to, the provisions relating to the payment of Rent, or if Tenant fails to renew the L/C at least thirty (30) days prior to the expiration thereof, Landlord may, but shall not be obligated to, draw upon all
or any portion of the L/C for payment of Rent or any other sum in default, or for the payment of any amount that Landlord may spend or become obligated to spend by reason of Tenant’s uncured default under Article 19.1 hereunder, or to
compensate Landlord for any other loss or damage that Landlord may suffer as a result of Tenant’s uncured default under Article 19.1 hereunder. The use, application or retention of the L/C or any portion thereof by Landlord shall not prevent
Landlord from exercising any and all other rights and remedies provided at law or by this Lease, it being intended that Landlord shall not first be required to proceed against the L/C and shall not operate as a limitation on any recovery to which
Landlord may otherwise be entitled. Any amount of the L/C which is drawn upon by Landlord, but is not used or applied by Landlord, shall be held by Landlord and deemed a Security Deposit pursuant to Section 21.2, above (the “L/C
Security Deposit”). If any portion of the L/C or the L/C Security Deposit is drawn upon by Landlord, Tenant shall, within five (5) days following written demand therefor by Landlord, either (i) deposit with Landlord cash in an

  
 -47-

 
amount sufficient that, when added to the L/C Security Deposit and any remaining amounts available under the L/C, is equal to amount of the L/C set forth in Section 10 of the Summary, or
(ii) reinstate the L/C to the amount set forth in Section 10 of the Summary, and Tenant’s failure to do so shall be a material default under this Lease entitling Landlord to exercise all of its rights and remedies hereunder. Tenant
acknowledges that the Landlord has the right to transfer or mortgage its interest in the Project and the Building and in this Lease and Tenant agrees that in the event of such a transfer or mortgage, Landlord shall have the right to transfer or
assign the L/C and/or the L/C Security Deposit to the transferee or mortgagee, and in the event of such a transfer, Tenant shall look solely to such transferee or mortgagee for the return of the L/C and/or the L/C Security Deposit. Tenant shall,
within ten (10) days of written request therefor by Landlord, execute such further documents, instruments or assurances as Landlord may deem reasonably necessary to evidence or confirm Landlord’s transfer or assignment of the L/C and/or
the L/C Security Deposit to such transferee or mortgagee. Provided that Tenant shall fully and faithfully perform all of its obligations under this Lease, the L/C and/or the L/C Security Deposit, or any balance remaining thereon, shall be returned
to Tenant following the expiration of the Lease Term. 
 21.4 Reduction in Letter of Credit.
As of the commencement of the Twenty-Fifth (25th) and Thirty-Seventh (37th ) full calendar month of the Lease Term, Tenant may request in
writing of Landlord that the amount of L/C amount be reduced by One Hundred Thousand Dollars ($100,000.00) on each such date (i.e., as of the commencement of the Twenty-Fifth (25th) full calendar month of the Lease Term, the L/C may be reduced to Two Hundred Thousand Dollars ($200,000.00),
and, provided that the L/C was reduced by One Hundred Thousand Dollars ($100,000.00) as of the commencement of the Twenty-Fifth (25th) full calendar month of the Lease Term, the L/C may be reduced to One Hundred Thousand Dollars ($100,000.00) as
of the commencement of the Thirty-Seventh (37th) full
calendar month of the Lease Term). Provided that prior to each such date Tenant has not previously been in monetary default of this Lease, Tenant may exchange a new L/C issued in the lower amount with Landlord and Landlord shall provide the original
L/C to Tenant upon receipt of the new L/C issued in the lower amount. 
 ARTICLE 22  

SUBSTITUTION OF OTHER PREMISES 
 Landlord shall have the right during the Lease Term and Option Term to relocate Tenant to other space in the Project comparable to the Premises, and all terms hereof shall apply to the new space with
equal force and effect, except as otherwise provided in this Article 22. In no event shall Landlord exercise such right more than one (1) time during the initial Lease Term and one (1) time during the Option Term timely and properly
exercised by Tenant. In any such event, Landlord shall give Tenant not less than one hundred twenty (120) days’ prior notice of Landlord’s election to so relocate Tenant, and shall move Tenant’s effects to the new space at
Landlord’s sole cost and expense at such time and in such manner as to inconvenience Tenant as little as reasonably practicable. Such new space (the “New Premises”) shall be as close as practicable in size and condition to the
existing Premises, and Landlord, at its sole cost and expense shall construct improvements in such New Premises to a standard reasonably equivalent (but no less than a Building standard condition) and in a configuration as close as reasonably
practicable to the existing Premises. In addition, Landlord shall reimburse Tenant for the 

  
 -48-

 
reasonable costs and expenses incurred by Tenant in connection with such relocation (including, but not limited to, the costs of reasonable supplies of replacement stationery, and the reasonable
costs of moving of any of Tenant’s furniture, equipment, personal property and the reasonable costs of moving and/or installing Tenant’s telephone and data systems installations not moved by Landlord), within thirty (30) days of
Landlord’s receipt of an invoice therefor. Simultaneously with such relocation of the Premises, the parties shall immediately execute an amendment to this Lease stating the relocation of the Premises, and amending those Sections of the Summary,
and replacing Exhibit A to this Lease, as shall be necessary to accurately describe the new space (including, without limitation, the location and the rentable area of the new space). In the event Tenant is relocated in accordance with
this Article 22, and the rentable area of the new space is not equal to the rentable area of the Premises, or any such adjustment to the rentable area of the Premises and/or the Building, all amounts, percentages and figures appearing or referred to
in this Lease based upon such rentable area (including, without limitation, the amounts of the “Rent” and the “Security Deposit,” as those terms are defined in Article 4 and Article 21 of this Lease, respectively, and
“Tenant’s Share,” as that term is defined in Section 4.2.9 of this Lease) shall be modified accordingly; provided that in the event that the rentable square footage of the New Premises is more than ten percent (10%) more
than the rentable square footage of the Premises, Tenant shall have no obligation to pay any Base Rent, Tenant’s Share or Security Deposit in excess of ten percent (10%) more than rentable square footage of the Premises. In no event shall
the rentable square footage of the New Premises be more than ten percent (10%) less than the rentable square footage of the Premises. Should Tenant refuse to permit Landlord to move Tenant to the new space, Landlord shall have the right to
cancel and terminate this Lease effective sixty (60) days from the date of Landlord’s election to relocate Tenant. 

ARTICLE 23  
 SIGNS 
 23.1 Multi-Tenant Floors. If other tenants
occupy space on the floor on which the Premises is located, Tenant’s identifying signage shall be provided by Landlord, at Landlord’s cost, and such signage shall be comparable to that used by Landlord for other similar floors in the
Building and shall comply with Landlord’s then-current Building standard signage program. In particular, Landlord shall provide Tenant with Building standard tenant directory identification signage in the ground floor lobby of the Building, and
Building standard tenant identification signage adjacent to Tenant’s entry door to the Premises. 
 23.2 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. Tenant
may not install any signs on the exterior or roof of the Project or the Common Areas. 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. 

ARTICLE 24  
 COMPLIANCE WITH LAW 

  
 -49-

 24.1 Compliance. 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, subject to the provisions of
Section 24.2, below. At its sole cost and expense, Tenant shall promptly comply with all such governmental measures, subject to the provisions of Section 24.2, below. 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 and to cooperate with Landlord, including, without limitation, by taking such actions as Landlord may reasonably require, in Landlord’s efforts to comply with such
standards or regulations. Tenant shall be responsible, at its sole cost and expense, to make all alterations to the 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. Tenant shall promptly pay all fines, penalties and damages that may arise out of or be imposed because of its failure to comply with the provisions of this Article 24. 

24.2 Special Provisions Relating to The Americans With Disabilities Act of 1990. 

24.2.1 Allocation of Responsibility to Landlord. As between Landlord and Tenant, Landlord shall be responsible, as
part of Operating Expenses, that the public entrances, stairways, corridors not located in the Premises, elevators and elevator lobbies in the Building comply with the requirements of Title III of the Americans with Disabilities Act of 1990 (42
U.S.C. 12181, et seq., The Provisions Governing Public Accommodations and Services Operated by Private Entities), and all regulations promulgated thereunder, and all amendments, revisions or modifications thereto now or hereafter adopted or in
effect in connection therewith (hereinafter collectively referred to as the “ADA”), and to take such actions and make such alterations and improvements as are necessary for such compliance. 

24.2.2 Allocation of Responsibility to Tenant. As between Landlord and Tenant, Tenant, at its sole cost and
expense, shall be responsible that the Premises, all Alterations to the Premises (including, without limitation, any Tenant Alterations), Tenant’s use and occupancy of the Premises, and Tenant’s performance of its obligations under this
Lease, comply with the requirements of the ADA as of the Commencement Date, and to take such actions and make such Alterations as are necessary for such compliance. In addition, as Tenant is designing the appearance, layout and amenities to the
Premises, and Tenant is the only entity that has knowledge of the persons who Tenant may employ or invite to the Premises who may have disabilities, Tenant shall be responsible for the compliance of the alterations, additions or other improvements
made by or on behalf of Tenant during the initial improvement of the Premises (as set forth in the Tenant Work Agreement attached as Exhibit B hereto) with ADA requirements. Landlord shall be responsible for building the initial
improvements to the Premises in accordance with the Final Construction Plans for the Tenant Improvements

 ARTICLE 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 upon the date said amount is due, then Tenant shall pay to Landlord a late charge
equal to six percent (6%) of the overdue amount plus any 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 upon 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.

Landlord the following sums (which sums shall bear interest from the date accrued by Landlord until paid by Tenant at a rate per annum equal to 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), 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 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.

 ARTICLE 27  

ENTRY BY LANDLORD 
 Landlord reserves the right at all reasonable times and upon reasonable notice to Tenant (which notice, notwithstanding anything to the contrary contained in Article 28 of this Lease, may be oral, and
which notice shall not be required in the case of an emergency) to enter the Premises to (i) inspect them; (ii) show the Premises to prospective purchasers or tenants, or to current or prospective mortgagees, ground or underlying lessors
or insurers; (iii) post notices of nonresponsibility; 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.
Notwithstanding anything to the contrary contained in this Article 27, Landlord may enter the Premises at any time to (A) perform services required of Landlord, including janitorial service; (B) take possession following any uncured
default under Article 19.1 of this Lease in the manner provided herein; and (C) perform any covenants of Tenant which Tenant fails to perform after such notice from Landlord and expiration of such cure period as is provided for hereunder.
Landlord may make any such entries without the abatement of Rent and may take such reasonable steps as required to accomplish the stated purposes. Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference
with Tenant’s business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby, provided that Landlord shall use commercially reasonable efforts not to materially and adversely affect
Tenant’s operations in, or access to, the Premises. For each of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas
designated in advance by Tenant. 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; provided that Landlord shall use commercially reasonable efforts not to
materially and adversely affect Tenant’s operations in, or access to, the Premises. No provision of this Lease shall be construed as obligating Landlord to perform any repairs, alterations or decorations except as otherwise expressly agreed to
be performed by Landlord herein.

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

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.

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.

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. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for any indirect or consequential damages or any injury or damage to, or interference
with, Tenant’s business, including but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each case, however occurring. 

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. 

  
 -55-

 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. Tenant does not rely on the fact, nor does Landlord represent, that any specific
tenant or type or number of tenants shall, during the Lease Term, occupy any space in the Building or Project. 
 29.16
Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire
or other casualty, and other causes beyond the reasonable control of the party obligated 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 occupancy of the Premises after any termination of this Lease. 

29.18 Tenant Parking. Tenant shall have the right to its pro-rata share of parking (3.3 vehicles for each 1,000 rentable
square feet of the Premises leased by Tenant, or 40 vehicles), free of charge, in the portions of the Common Areas designated by Landlord for vehicular parking. Such parking shall be on an as available “first-come, first-served” basis
which shall be in common with all other tenants of the Project. Tenant’s continued right to use the parking areas is conditioned upon Tenant abiding by all reasonable written rules and regulations which are prescribed from time to time for the
orderly operation and use of the parking areas, Tenant’s cooperation in seeing that Tenant’s employees and visitors also comply with such rules and regulations and Tenant not being in default under this Lease. Landlord specifically
reserves the right to change the size, configuration, design, layout and all other aspects of the Project parking areas at any time, provided such work does not reduce Tenant’s pro-rata share of parking spaces (or if it does, Landlord provides
reasonable alternative parking for Tenant), and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, close-off or restrict access to the
Project parking areas for purposes of permitting or facilitating any construction, alteration or improvements of or to the Project, provided that once any such work is commenced, Landlord diligently pursues it to completion. Landlord may delegate
its responsibilities hereunder to a parking operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord. Tenant may validate visitor parking by such method or methods as the Landlord may
establish, at the validation rate from time to time generally applicable to visitor parking. 
 29.19 Joint and
Several. If there is more than one Tenant, the obligations imposed upon Tenant under this Lease shall be joint and several.

 29.20 Authority. If Tenant is a corporation, trust, limited liability company
or partnership, each individual executing this Lease on behalf of Tenant hereby represents and warrants that Tenant is a duly formed and existing entity qualified to do business in California and that Tenant has full right and authority to execute
and deliver this Lease and that each person signing on behalf of Tenant is authorized to do so. In such event, Tenant shall, within ten (10) business days after execution of this Lease, deliver to Landlord satisfactory evidence of such
authority and, if a corporation, promptly following written demand by Landlord, also deliver to Landlord satisfactory evidence of (i) good standing in Tenant’s state of incorporation and (ii) qualification to do business in
California. 
 29.21 Attorneys’ Fees. In the event that either Landlord or Tenant should bring suit for the
possession of the Premises, for the recovery of any sum due under this Lease, or because of the breach of any provision of this Lease or for any other relief against the other, then all costs and expenses, including reasonable attorneys’ fees,
incurred by the prevailing party therein shall be paid by the other party, which obligation on the part of the other party shall be deemed to have accrued on the date of the commencement of such action and shall be enforceable whether or not the
action is prosecuted to judgment. 
 29.22 Governing Law; WAIVER OF TRIAL BY JURY. This Lease shall be construed
and enforced in accordance with the laws of the State of California. IN ANY ACTION OR PROCEEDING ARISING HEREFROM, LANDLORD AND TENANT HEREBY CONSENT TO (I) THE JURISDICTION OF ANY COMPETENT COURT WITHIN THE STATE OF CALIFORNIA, (II) SERVICE OF
PROCESS BY ANY MEANS AUTHORIZED BY CALIFORNIA LAW, AND (III) IN THE INTEREST OF SAVING TIME AND EXPENSE, TRIAL WITHOUT A JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER OR THEIR SUCCESSORS IN
RESPECT OF ANY MATTER ARISING OUT OF OR IN CONNECTION WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT’S USE OR OCCUPANCY OF THE PREMISES, AND/OR ANY CLAIM FOR INJURY OR DAMAGE, OR ANY EMERGENCY OR STATUTORY REMEDY. IN THE EVENT
LANDLORD COMMENCES ANY SUMMARY PROCEEDINGS OR ACTION FOR NONPAYMENT OF BASE RENT OR ADDITIONAL RENT, TENANT SHALL NOT INTERPOSE ANY COUNTERCLAIM OF ANY NATURE OR DESCRIPTION (UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR
ACTION, BUT SHALL BE RELEGATED TO AN INDEPENDENT ACTION AT LAW. 
 29.23 Submission of Lease. Submission of this
instrument for examination or signature by Tenant does not constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant. 

29.24 Brokers. 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 Lease, excepting only the real estate brokers or agents specified in Section 11 of the Summary (the “Brokers”), and that they know of no other real estate broker or agent who
is entitled to a commission in connection with this Lease. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, costs and
expenses (including without limitation reasonable

Brokers, occurring by, through, or under the indemnifying party. 
 29.25 Independent Covenants. This Lease shall
be construed as though the covenants herein between Landlord and Tenant are independent and not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its obligations set
forth herein, Tenant shall not be entitled to make any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord, except as expressly stated to the contrary in
this Lease. 
 29.26 Project or Building Name and Signage. Landlord shall have the right at any time to change the
name of the Project or Building and to install, affix and maintain any and all signs on the exterior and on the interior of the Project or Building as Landlord may, in Landlord’s sole discretion, desire. Tenant shall not use the words
“Gateway Center” or the name of the Project or Building or use pictures or illustrations of the Project or Building in advertising or other publicity or for any purpose other than as the address of the business to be conducted by
Tenant in the Premises, without the prior written consent of Landlord.

reciprocal rights of access and/or use of the Project and the Other Improvements, (ii) for the common management, operation, maintenance, improvement and/or repair of all or any portion of the Project and the Other Improvements, (iii) for

29.29.3 Construction of Project and Other Improvements. Tenant acknowledges that portions of the Project
and/or the Other Improvements may be under construction following Tenant’s occupancy of the Premises, and that such construction may result in levels of noise, dust, odor, obstruction of access, etc. which are in excess of that present in a
fully constructed project. Tenant hereby waives any and all rent offsets or claims of constructive eviction which may arise in connection with such construction, provided that once any such work is commenced, Landlord diligently pursues same to
completion. 
 29.30 Building Renovations. It is specifically understood and agreed that Landlord has no
obligation and has made no promises to alter, remodel, improve, renovate, repair or decorate the Premises, Building, or any part thereof and that no representations respecting the condition of the Premises or the Building have been made by Landlord
to Tenant except as specifically set forth herein or in the Tenant Work Letter. However, Tenant hereby acknowledges that Landlord is currently renovating or may during the Lease Term renovate, improve, alter, or modify (collectively, the
“Renovations”) the Project, the Building and/or the Premises. Tenant hereby agrees that such Renovations shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of Rent. Landlord shall have
no responsibility and shall not be liable to Tenant for any injury to or interference with Tenant’s business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of the use of the
whole or any part of the Premises or of Tenant’s personal property or improvements resulting from the Renovations, or for any inconvenience or annoyance occasioned by such Renovations, provided that once any such Renovations are commenced,
Landlord diligently pursues same to completion. 
 29.31 No Violation. Tenant hereby warrants and represents that
neither its execution of nor performance under this Lease shall cause Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and hold Landlord
harmless against any claims, demands, losses, damages, liabilities, costs and expenses, including, without limitation, reasonable attorneys’ fees and costs, arising from Tenant’s breach of this warranty and representation.

as determined in Landlord’s reasonable opinion, (iii) the Lines therefor (including riser cables) shall be appropriately insulated to prevent excessive electromagnetic fields or radiation, and shall be surrounded by a protective conduit
reasonably acceptable to Landlord, (iv) any new or existing Lines servicing the Premises shall comply with all applicable governmental laws and regulations, (v) as a condition to permitting the installation of new Lines, Landlord may
require that Tenant remove existing Lines located in or serving the Premises and installed for or by Tenant and repair any damage in connection with such removal,

 4.2 Approved Preliminary
Plans. The Preliminary Plans approved by both Landlord and Tenant (“Approved Preliminary Plans”) are attached hereto as Exhibit A and shall be used by Architect to develop the construction plans, 

5. Construction Plans for Tenant Improvements. Architect shall provide Landlord with completed construction plans showing

shall submit the Construction Plans to the appropriate governmental body for plan checking and a Building Permit, if required. The Construction Plans that the Building Permit has been granted for shall hereinafter be known as the “Final
Construction Plans”. 
 7. Bids. Once the Final Construction Plans have been obtained, Landlord shall request
a bid from the Contractor for the construction of the Tenant Improvements based upon the Final Construction Plans (the “Bid”). In the event that the amount of such Bid, when added to Landlord’s Fee, is equal to or less than the Base
Tenant Improvement Allowance, Landlord may accept such Bid in its sole and absolute discretion and have Contractor construct the Tenant Improvements. 
 7.1 Additional Bids. In the event that the amount of such Bid, when added to Landlord’s Fee, is more than the Base Tenant Improvement Allowance, Landlord shall

share such Bid with Tenant on an open book basis. Tenant, in its reasonable discretion, may elect, within five (5) business days after receiving such Bid from Landlord, to solicit additional
bids from no more than two (2) other California licensed general contractors based upon the Final Construction Plans. Once the two other bids have been received, Tenant shall review all three bids and shall, within five (5) business days
thereafter, select one of the three contractors to construct the Tenant Improvements for the bid (hereinafter, the “Final Bid”) selected by Tenant. Any delays resulting from Tenant’s reviewing and approving the bids shall be a Tenant
Delay, if such review and approval period exceeds five (5) business days following delivery to Tenant of all bids. 
 7.2 Tenant’s Payment. Landlord may require Tenant to pay to Landlord prior to the construction of the Tenant Improvements, the amount by which the Final Bid exceeds the Base Tenant Improvement
Allowance. 
 7.3 Payment of Contractor. In the alternative, in Landlord’s sole and absolute
discretion, Landlord may elect to allow Tenant to pay its share of the Final Bid price pursuant to the following procedure. Once Landlord and Tenant have agreed upon the Final Bid and a contract for the Final Bid price has been entered into with the
contractor, Landlord shall be responsible for making monthly progress payments to the contractor in accordance with the construction contract, subject to reimbursement by Tenant pursuant to the following procedure. Tenant shall reimburse Landlord
each month, within twenty (20) days of receipt of bills or invoices representing the current months’ payment obligation to the contractor (the “Monthly Payment”), for that portion of the Monthly Payment determined by taking a
fraction, the numerator of which is the difference between the Final Bid and the Base Leasehold Improvement Allowance, and the denominator of which is the Final Bid, and multiplying the Monthly Payment by such fraction. Landlord shall have no
obligation to pay the contractor unless and until Landlord shall have received such sum from Tenant. Any delays in construction of the Tenant Improvements caused as a result of Tenant’s failure to timely reimburse Landlord as provided herein,

(ii) to the Final Construction Plans, or (iii) to any Tenant Improvements already constructed by Landlord in such Premises pursuant to this Tenant Work Letter (each, a “Change Request”) shall be made without Landlord’s prior
written approval, which approval shall not be unreasonably withheld, conditioned or delayed, subject to the following: 
 (i) No Change Request shall affect the structure or operating systems of the Building; 
 (ii) Landlord may require Tenant to pay to Landlord prior to the implementation of any Change Request, the amount by which Landlord’s cost of constructing the Tenant Improvements, after

caused by any delay in construction of the Tenant Improvements as a result of a Change Request; provided that if Tenant determines that the cost of the Change Request proposed by Landlord is not
reasonably acceptable to Tenant, Tenant may rescind the proposal for a Change Request, and shall have no further liability to Landlord for the proposed Change Request under this Tenant Work Letter following such rescission except for any costs to
Landlord caused by any Tenant Delay caused by the process of beginning to implement such Change Request at the request of Tenant; 
 (iii) A Change Request shall constitute an agreement by Tenant to any delay in completion of the Tenant Improvements caused by Landlord’s reviewing, processing and implementing the Change Request,
all of which delays shall be deemed a Tenant Delay; 
 (iv) Lessor shall accept only Change Requests signed by
Tenant’s representative, George Jue. Tenant may from time to time designate a different representative to authorize Change Requests. 
 (v) Any delays in completion of the Tenant Improvements caused as a result of a Change Request shall not delay the Lease Commencement Date from the date the Lease Commencement Date would otherwise have
occurred, in the reasonable opinion of Landlord, had it not been for the Change Request. Tenant agrees that the Lease and all obligations of Tenant thereunder (including, without limitation, the obligation to pay Rent) shall commence on the date
that the Lease Commencement Date would otherwise have occurred had it not been for the Change Request. 
 8.2
Procedure. Except with respect to the mechanical and electrical systems of the Building, Landlord shall confirm, in writing, Landlord’s approval or disapproval within five (5) business days after receipt of Tenant’s written
proposal for a Change Request. All costs paid by Landlord to unaffiliated parties in connection with review of Tenant’s proposed Change Requests, if such costs shall cause Landlord to exceed the Base Tenant Improvement Allowance, shall be
reimbursed by Tenant to Landlord promptly following Landlord’s written demand therefore. With respect to a Tenant-proposed Change Request related to the Building’s mechanical and electrical systems, Landlord shall have seven
(7) business days to confirm its approval or disapproval in writing. 
 8.3 Notification. At the time
of Landlord ‘s notification pursuant to Section 8.2, Landlord shall inform Tenant of Landlord’s estimate of the increased costs (if any) of constructing the Tenant Improvements which will be incurred as a result of the proposed Change
Request and the Tenant Delay which will result from the Change Request. If Tenant agrees with Landlord’s estimate of the increased cost and period of Tenant Delay associated with the proposed Change Request, the parties shall document the
Change Request by means of a written agreement or work order signed by Landlord and Tenant. Landlord shall not perform the work of any proposed Change Order unless and until such Change Order is so documented by the parties. 

8.4 Period of Review. The period of Landlord’s review of a proposed Change Request shall be deemed a Tenant
Delay.

consent of Tenant, to order any changes to the Tenant Improvements required by applicable laws or regulations, and to order minor changes in the Tenant Improvements not involving a delay in the completion of the Tenant Improvements, Delays caused by
Landlord’s compliance with laws or regulations shall not be deemed delays within Landlord’s control, and Landlord shall have no responsibility or liability with respect thereto. 

10. Delivery of Premises. Following Substantial Completion of the Premises, Landlord shall deliver possession of the
Premises to Tenant. The Lease Commencement Date shall be the date that Landlord delivers possession of the Premises to Tenant with the Tenant Improvements Substantially Completed.

 STANDARDS FOR UTILITIES AND SERVICES 
 1. Elevators. Provide
non-attended passenger elevators to and from the floor(s) on which the Premises are located. Landlord may limit the number of elevators operating outside normal business hours. 

2. HVAC. On Monday through Friday, except holidays, from 7:00 a.m. to 6:00 p.m., ventilate the Premises and furnish air
conditioning or heating on such days and hours, in temperatures and amounts which in Landlord’s good faith judgment are reasonably required for comfortable occupancy of the Premises under normal business operations. If Tenant requires air
conditioning during other hours, Landlord will furnish same through an access system provided to Tenant at the Premises, if available, or otherwise as specified in a written request of Tenant delivered to the Building management office before noon
on the preceding business day. For this service Tenant will pay Landlord, upon receipt of Landlord’s statement, the charge at an hourly rate determined by Landlord from time to time, which is currently $35.00 per hour. Tenant agrees that
neither Tenant nor any Tenant Party shall at any time enter mechanical installations or facilities of the Building or adjust, tamper with, touch or otherwise in any manner affect said installations or facilities. The cost of maintenance and service
calls to adjust and regulate the air conditioning system shall be charged to Tenant if the need for maintenance work results from either Tenant’s adjustment of room thermostats or Tenant’s failure to comply with Landlord’s rules
governing the temperature within the Premises. 
 3. Lighting. Furnish electric lighting for all public areas and special
service areas of the Building as Landlord determines in good faith to be reasonable and standard, including replacement of Building standard lights, bulbs and tubes. 
 4. Electrical Service. Subject to the limitation of this Paragraph 4, furnish electrical service to the Premises, including providing and installing all Building standard replacement lighting
tubes. If Tenant uses more electrical power than Landlord in good faith considers reasonable or normal for office use, Tenant will pay Landlord on a monthly basis the cost of such excess power consumed by Tenant. Consumption will be determined, at
Landlord’s election, either (a) by a survey performed by a reputable consultant selected by Landlord, or (b) through separate meters or submeters installed, maintained and read by Landlord at Tenant’s cost. For purposes of this
Paragraph 4 only, “month” and “monthly” shall mean any billing period used by the utility or other power provider supplying electricity. All installations of electrical fixtures, appliances and equipment within the Premises shall
be subject to Landlord’s prior approval, and if they affect the temperature or humidity otherwise maintained, Landlord may, at Tenant’s sole cost and expense (to be paid within (30) days after delivery of written demand supported by
invoices or other reasonably satisfactory evidence), install supplemental air conditioning units. Tenant’s use of electricity shall never exceed Tenant’s share of the capacity of existing feeders to the Building or of the risers, wiring
installations and transformers serving

the floor(s) containing the Premises. Landlord shall provide up to 3.5 watts per usable square foot (demand) of riser and floor panel electrical capacity averaged over the floor being serviced.
Tenant shall be allocated an approximate 2.0 watts per usable square foot for power and 1.5 watts per usable square foot for lighting. Any risers or wiring necessary to meet Tenant’s excess electrical requirements will be installed by Landlord
on Tenant’s request, at Tenant’s sole cost and expense (to be paid in advance), but only if in Landlord’s good faith belief they are necessary and will not cause damage to the Building or a dangerous condition, entail excessive or
unreasonable alterations, repairs or expense, or disturb other occupants. 
 5. Water. Provide toilet facilities, water
for lavatory and toilet purposes, cold water for drinking and tepid water for lavatory purposes, all at points of supply provided for general use of tenants in the Building through fixtures installed by Landlord or by Tenant with Landlord’s
consent. 
 6. Janitorial. Provide janitorial service to the Premises on business days and other cleaning services as
Landlord determines to be reasonably required. Tenant will pay Landlord the full cost attributable to any extraordinary janitorial or cleaning services which the Premises may require. 

7. Maintenance of Non-Building Standard Items. Maintenance and service costs necessary for non-building standard items in the
Premises shall be the responsibility of Tenant. As used in this paragraph, non-building standard items shall include, without limitation, heat pumps, condenser pumps, sinks and associated drain pipes, faucets, hot water heaters, garbage disposals,
dishwashers, refrigerators, ice makers, air conditioning units, projection screens and associated wiring and switching, incandescent downlight or wallwash fixtures and lamps, floor electrical outlets and power poles. 

8. Security Services. Provide Building security personnel twenty-four (24) hours per day, seven (7) days per week,
fifty-two (52) weeks per year and a card access system which allows access to individual office floors twenty-four (24) hours per day, seven (7) days per week, fifty-two (52) weeks per year, all of which shall be provided by
Landlord in its sole and absolute discretion. Notwithstanding Landlord’s providing security, Tenant waives any claim against Landlord with respect to any loss by theft or any other damage suffered or incurred by Tenant in connection with any
entry into the Premises or any other breach of security with respect to the Premises or the Building, except due to the gross negligence or willful misconduct of Landlord. 
 Landlord reserves the right to adopt reasonably, nondiscriminatory modifications and additions to these standards, which Landlord shall promptly deliver to Tenant in writing.
