1. GENERAL. 
 (a)
Eligible Stock Award Recipients. The persons eligible to receive Stock Awards are Employees, Directors and Consultants. 
 (b)
Available Stock Awards. The Plan provides for the grant of the following Stock Awards: (i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights, (iv) Restricted Stock Awards, and
(v) Restricted Stock Unit Awards. 
 (c) Purpose. The Company, by means of the Plan, seeks to secure and retain the
services of the group of persons eligible to receive Stock Awards as set forth in Section 1(a), to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate, and to provide a means by which
such eligible recipients may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Stock Awards. 
 2.
ADMINISTRATION. 
 (a) Administration by Board. The Board shall administer the Plan unless and until the
Board delegates administration of the Plan to a Committee or Committees, as provided in Section 2(c). 
 (b) Powers of
Board. The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan: 
 (i) To
determine from time to time (A) which of the persons eligible under the Plan shall be granted Stock Awards; (B) when and how each Stock Award shall be granted; (C) what type or combination of types of Stock Award shall be granted;
(D) the provisions of each Stock Award granted (which need not be identical), including the time or times when a person shall be permitted to receive cash or Common Stock pursuant to a Stock Award; (E) the number of shares of Common Stock
with respect to which a Stock Award shall be granted to each such person; and (F) the Fair Market Value applicable to a Stock Award. 

  
 1. 

 (ii) To construe and interpret the Plan and Stock Awards granted under it, and to
establish, amend and revoke rules and regulations for administration of the Plan. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement, in a manner and to the extent
it shall deem necessary or expedient to make the Plan or Stock Award fully effective. 
 (iii) To settle all controversies regarding
the Plan and Stock Awards granted under it. 
 (iv) To accelerate the time at which a Stock Award may first be exercised or the time
during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it will vest. 

(v) To suspend or terminate the Plan at any time. Suspension or termination of the Plan shall not impair rights and obligations under
any Stock Award granted while the Plan is in effect except with the written consent of the affected Participant. 
 (vi) To amend the
Plan in any respect the Board deems necessary or advisable, including, without limitation, amendments relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to bring the Plan or
Stock Awards granted under the Plan into compliance therewith, subject to the limitations, if any, of applicable law. However, except as provided in Section 9(a) relating to Capitalization Adjustments, to the extent required by applicable law,
stockholder approval shall be required for any amendment of the Plan that either (A) materially increases the number of shares of Common Stock available for issuance under the Plan, (B) materially expands the class of individuals eligible
to receive Stock Awards under the Plan, (C) materially increases the benefits accruing to Participants under the Plan or materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (D) materially
extends the term of the Plan, or (E) expands the types of Stock Awards available for issuance under the Plan. Except as provided above, rights under any Stock Award granted before amendment of the Plan shall not be impaired by any amendment of
the Plan unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.  

(vii) To submit any amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to
satisfy the requirements of Section 422 of the Code regarding Incentive Stock Options. 
 (viii) To approve forms of Stock Award
Agreements for use under the Plan and to amend the terms of any one or more Stock Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Stock Award Agreement, subject to
any specified limits in the Plan that are not subject to Board discretion; provided however, that, the rights under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the consent of the affected
Participant, and (ii) such 

  
 2. 

 
Participant consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, and without the affected Participant’s consent, the Board may amend the
terms of any one or more Stock Awards if necessary to maintain the qualified status of the Stock Award as an Incentive Stock Option or to bring the Stock Award into compliance with Section 409A of the Code. 

(ix) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best
interests of the Company and that are not in conflict with the provisions of the Plan or Stock Awards. 
 (x) To adopt such
procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees, Directors or Consultants who are foreign nationals or employed outside the United States. 

(xi) To effect, at any time and from time to time, with the consent of any adversely affected Participant, (A) the reduction of
the exercise price (or strike price) of any outstanding Option or SAR under the Plan, (B) the cancellation of any outstanding Option or SAR under the Plan and the grant in substitution therefore of (1) a new Option or SAR under the Plan or
another equity plan of the Company covering the same or a different number of shares of Common Stock, (2) a Restricted Stock Award, (3) a Restricted Stock Unit Award, (4) cash and/or (5) other valuable consideration (as
determined by the Board, in its sole discretion), or (C) any other action that is treated as a repricing under generally accepted accounting principles; provided, however, that no such reduction or cancellation may be effected if it is
determined, in the Company’s sole discretion, that such reduction or cancellation would result in any such outstanding Option becoming subject to the requirements of Section 409A of the Code.  

(c) Delegation to Committee. The Board may delegate some or all of the administration of the Plan to a Committee or Committees.
If administration of the Plan is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to
delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee), subject, however, to such
resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some
or all of the powers previously delegated. 
 (d) Delegation to an Officer. The Board may delegate to one or more Officers of
the Company the authority to do one or both of the following: (i) designate Officers and Employees of the Company or any of its Subsidiaries to be recipients of Options and Stock Appreciation Rights (and, to the extent permitted by applicable
law, other Stock Awards) and the terms thereof, and (ii) determine the number of shares of Common Stock to be subject to such Stock Awards granted to such Officers and Employees; provided, however, that the Board resolutions regarding
such delegation shall specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award to himself or herself. Notwithstanding the foregoing, the
Board may not delegate authority to an Officer to determine the Fair Market Value pursuant to Section 13(t) below. 

  
 3. 

 (e) Effect of Board’s Decision. All determinations,
interpretations and constructions made by the Board in good faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons. 

(f) Arbitration. Any dispute or claim concerning any Stock Awards granted (or not granted) or any disputes or claims relating to
or arising out of the Plan shall be fully, finally and exclusively resolved by binding and confidential arbitration conducted pursuant to the Commercial Arbitration Rules of the American Arbitration Association in San Francisco, California. The
Company shall pay all arbitration fees. In addition to any other relief, the arbitrator may award to the prevailing party recovery of its attorneys’ fees and costs. By accepting a Stock Award, Participants and the Company waive their respective
rights to have any such disputes or claims tried by a judge or jury. 
 3. SHARES SUBJECT TO
THE PLAN. 
 (a) “Share Reserve. Subject to the provisions of Section 9(a)
relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards beginning on the Effective Date shall not exceed 22,909,874 shares (the
“Share Reserve”). Furthermore, if a Stock Award (i) expires or otherwise terminates without having been exercised in full or (ii) is settled in cash
(i.e., the holder of the Stock Award receives cash rather than stock), such expiration, termination or settlement shall not reduce (or otherwise offset) the number of shares of Common Stock that may be issued pursuant to the Plan. For
clarity, the limitation in this Section 3(a) is a limitation in the number of shares of Common Stock that may be issued pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in
Section 7(a). 
 (b) Reversion of Shares to the Share Reserve. If any shares of Common Stock issued pursuant to a Stock
Award are forfeited back to the Company because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares which are forfeited shall revert to and again become available for issuance under the
Plan. Also, any shares reacquired by the Company pursuant to Section 8(g) or as consideration for the exercise of an Option shall again become available for issuance under the Plan. Notwithstanding the provisions of this Section 3(b), any
such shares shall not be subsequently issued pursuant to the exercise of Incentive Stock Options. 
 (c) Incentive Stock Option
Limit. Notwithstanding anything to the contrary in this Section 3(c), subject to the provisions of Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant
to the exercise of Incentive Stock Options shall be two (2) times the Share Reserve.  
 (d) Source of Shares. The
stock issuable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise.” 

  
 4. 

 4. ELIGIBILITY. 

(a) Eligibility for Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a
“parent corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and (f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and
Consultants; provided, however, Nonstatutory Stock Options and SARs may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company, as such term is defined in
Rule 405, unless the stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code because the Stock Awards are granted pursuant to a corporate transaction (such as a spin off
transaction) or unless such Stock Awards comply with the distribution requirements of Section 409A of the Code. 
 (b) Ten
Percent Stockholders. A Ten Percent Stockholder shall not be granted an Incentive Stock Option unless the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the Option
is not exercisable after the expiration of five (5) years from the date of grant. 
 (c) Consultants. A Consultant shall not be
eligible for the grant of a Stock Award if, at the time of grant, either the offer or the sale of the Company’s securities to such Consultant is not exempt under Rule 701 because of the nature of the services that the Consultant is
providing to the Company, because the Consultant is not a natural person, or because of any other provision of Rule 701, unless the Company determines that such grant need not comply with the requirements of Rule 701 and will satisfy
another exemption under the Securities Act as well as comply with the securities laws of all other relevant jurisdictions. 
 5.
PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS. 

Each Option or SAR shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be
separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates shall be issued for shares of Common Stock purchased on exercise of each type
of Option. If an Option is not specifically designated as an Incentive Stock Option, then the Option shall be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not be identical; provided, however, that each Option
Agreement or Stock Appreciation Right Agreement shall conform to (through incorporation of provisions hereof by reference in the applicable Stock Award Agreement or otherwise) the substance of each of the following provisions: 

(a) Term. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or SAR shall be
exercisable after the expiration of ten (10) years from the date of its grant or such shorter period specified in the Stock Award Agreement. 

(b) Exercise Price. Subject to the provisions of Section 4(b) regarding Incentive Stock Options granted to Ten Percent
Stockholders, the exercise price (or strike price) of each Option or SAR shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Option or SAR is granted.
Notwithstanding the foregoing, an Option or SAR may be granted with an exercise price (or strike price) lower than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR if such Option or SAR is
granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Sections 409A and 424(a) of the Code (whether or not such
Stock Awards are Incentive Stock Options). Each SAR will be denominated in shares of Common Stock equivalents. 

  
 5. 

 (c) Consideration for Options. The purchase price of Common Stock acquired
pursuant to the exercise of an Option shall be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board shall have the authority to
grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment. The permitted
methods of payment are as follows: 
 (i) by cash, check, bank draft or money order payable to the Company; 

(ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of
the stock subject to the Option, 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; 

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock; 

(iv) if the Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant to which the Company will
reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or
other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued; provided, further, that shares of Common Stock will no
longer be subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are reduced to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the
Participant as a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 
 (v)
according to a deferred payment or similar arrangement with the Optionholder; provided, however, that interest shall compound at least annually and shall be charged at the minimum rate of interest necessary to avoid (A) the imputation of
interest income to the Company and compensation income to the Optionholder under any applicable provisions of the Code, and (B) the classification of the Option as a liability for financial accounting purposes; or 

(vi) in any other form of legal consideration that may be acceptable to the Board. 

(d) Exercise and Payment of a SAR. To exercise any outstanding Stock Appreciation Right, the Participant must provide written
notice of exercise to the Company in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. The appreciation distribution payable on the exercise of a Stock Appreciation Right will be not
greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the Stock Appreciation Right) of a number of shares of Common Stock 

  
 6. 

 
equal to the number of Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to which the Participant is exercising the Stock
Appreciation Right on such date, over (B) the strike price that will be determined by the Board at the time of grant of the Stock Appreciation Right. The appreciation distribution in respect to a Stock Appreciation Right may be paid in Common
Stock, in cash, in any combination of the two or in any other form of consideration, as determined by the Board and contained in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 

(e) Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations on the transferability
of Options and SARs as the Board shall determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs shall apply: 

(i) Restrictions on Transfer. An Option or SAR shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Participant only by the Participant; provided, however, that the Board may, in its sole discretion, permit transfer of the Option or SAR to such extent as permitted by
Rule 701 and in a manner consistent with applicable tax and securities laws upon the Participant’s request. 
 (ii)
Domestic Relations Orders. Notwithstanding the foregoing, an Option or SAR may be transferred pursuant to a domestic relations order; provided, however, that if an Option is an Incentive Stock Option, such Option may be deemed to be a
Nonstatutory Stock Option as a result of such transfer. 
 (iii) Beneficiary Designation. Notwithstanding the foregoing, the
Participant may, by delivering written notice to the Company, in a form provided by or otherwise satisfactory to the Company and any broker designated by the Company to effect Option exercises, designate a third party who, in the event of the death
of the Participant, shall thereafter be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, the executor or administrator of the
Participant’s estate shall be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. 

(f) Vesting Generally. The total number of shares of Common Stock subject to an Option or SAR may vest and therefore become
exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not be exercised (which may be based on the satisfaction of performance
goals or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to any Option or SAR provisions governing the minimum number of shares of
Common Stock as to which an Option or SAR may be exercised. 
 (g) Termination of Continuous Service. Except as otherwise
provided in the applicable Stock Award Agreement or other agreement between the Participant and the Company, in the event that a Participant’s Continuous Service terminates (other than for Cause or upon the Participant’s death or
Disability), the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Stock Award as of the date of termination 

  
 7. 

 
of Continuous Service) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Participant’s Continuous
Service (or such longer or shorter period specified in the Stock Award Agreement, which period shall not be less than thirty (30) days if necessary to comply with applicable state laws unless such termination is for Cause) or (ii) the
expiration of the term of the Option or SAR as set forth in the Stock Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the time specified herein or in the Stock Award
Agreement (as applicable), the Option or SAR shall terminate. 
 (h) Extension of Termination Date. Except as otherwise
provided in the applicable Stock Award Agreement or other agreement between the Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause or upon the
Participant’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option or SAR shall terminate on the earlier
of (i) the expiration of a period of three (3) months after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of such registration requirements, or
(ii) the expiration of the term of the Option or SAR as set forth in the Stock Award Agreement. In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock received upon exercise of an Option
or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the Option or SAR shall terminate on the earlier of (i) the expiration of a
period equal to the applicable post-termination exercise period after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in violation of the Company’s insider trading policy,
or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Stock Award Agreement. 

(i) Disability of Participant. Except as otherwise provided in the applicable Stock Award Agreement or other
agreement between the Participant and the Company, in the event that a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her Option or SAR (to the extent that the
Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination of
Continuous Service (or such longer or shorter period specified in the Stock Award Agreement, which period shall not be less than six (6) months if necessary to comply with applicable state laws), or (ii) the expiration of the term of
the Option or SAR as set forth in the Stock Award Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR within the time specified herein or in the Stock Award Agreement (as applicable),
the Option or SAR shall terminate. 
 (j) Death of Participant. Except as otherwise provided in the applicable Stock Award
Agreement or other agreement between the Participant and the Company, in the event that (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the period (if
any) specified in the Stock Award Agreement after the termination of the Participant’s Continuous Service for a reason other than death, then the Option or SAR may be exercised (to the extent the Participant was entitled to exercise such Option
or SAR as of the date of death) by the Participant’s estate, by a person who acquired the right to 

  
 8. 

 
exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the Participant’s death, but only within the period ending on the earlier of
(i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Stock Award Agreement, which period shall not be less than six (6) months if necessary to comply with
applicable state laws), or (ii) the expiration of the term of such Option or SAR as set forth in the Stock Award Agreement. If, after the Participant’s death, the Option or SAR is not exercised within the time specified herein or in the
Stock Award Agreement (as applicable), the Option or SAR shall terminate. 
 (k) Termination for Cause. Except as explicitly
provided otherwise in a Participant’s Stock Award Agreement, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR shall terminate upon the termination date of such Participant’s Continuous Service, and the
Participant shall be prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous Service. 

(l) Non-Exempt Employees. No Option or SAR granted to an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, shall be first exercisable for any shares of Common Stock until at least six months following the date of grant of the
Option or SAR. Notwithstanding the foregoing, consistent with the provisions of the Worker Economic Opportunity Act, in the event of the Participant’s death or Disability, upon a Corporate Transaction or a Change in Control in which the vesting
of such Options or SARs accelerates, or upon the Participant’s retirement (as such term may be defined in the Participant’s Stock Award Agreement or in another applicable agreement or in accordance with the Company’s then current
employment policies and guidelines) any such vested Options and SARs may be exercised earlier than six months following the date of grant. The foregoing provision is intended to operate so that any income derived by a
non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. 

(m) Early Exercise of Options. An Option may, but need not, include a provision whereby the Optionholder may elect at any time
before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. Subject to the
“Repurchase Limitation” in Section 8(l), any unvested shares of Common Stock so purchased may be subject to a repurchase right in favor of the Company or to any other restriction the Board determines to be appropriate. Provided
that the “Repurchase Limitation” in Section 8(l) is not violated, the Company shall not be required to exercise its repurchase right until at least six (6) months (or such longer or shorter period of time required to
avoid classification of the Option as a liability for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option Agreement. 

(n) Right of Repurchase. Subject to the “Repurchase Limitation” in Section 8(l), the Option or SAR may
include a provision whereby the Company may elect to repurchase all or any part of the vested shares of Common Stock acquired by the Participant pursuant to the exercise of the Option or SAR. 

  
 9. 

 (o) Right of First Refusal. The Option or SAR may include a provision whereby
the Company may elect to exercise a right of first refusal following receipt of notice from the Participant of the intent to transfer all or any part of the shares of Common Stock received upon the exercise of the Option or SAR. Such right of first
refusal shall be subject to the “Repurchase Limitation” in Section 8(l). Except as expressly provided in this Section 5(o) or in the Stock Award Agreement, such right of first refusal shall otherwise comply with any
applicable provisions of the Bylaws of the Company. 
 6. PROVISIONS OF RESTRICTED STOCK
AWARDS AND RESTRICTED STOCK UNITS. 
 (a)
Restricted Stock Awards. Each Restricted Stock Award Agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. To the extent consistent with the Company’s Bylaws, at the Board’s
election, shares of Common Stock may be (x) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, which certificate shall
be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical;
provided, however, that each Restricted Stock Award Agreement shall conform to (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 

(i) Consideration. A Restricted Stock Award may be awarded in consideration for (A) cash or cash equivalents, (B) past
or future services actually or to be rendered to the Company or an Affiliate, or (C) any other form of legal consideration that may be acceptable to the Board in its sole discretion and permissible under applicable law. 

(ii) Vesting. Subject to the “Repurchase Limitation” in Section 8(l), shares of Common Stock awarded under
the Restricted Stock Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 

(iii) Termination of Participant’s Continuous Service. If a Participant’s Continuous Service terminates, the Company
may receive through a forfeiture condition or a repurchase right, any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award
Agreement. 
 (iv) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement shall
be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board shall determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award
Agreement remains subject to the terms of the Restricted Stock Award Agreement. 
 (v) Dividends. A Restricted Stock Award
Agreement may provide that any dividends paid on Restricted Stock will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

  
 10. 

 (b) Restricted Stock Unit Awards. Each Restricted Stock Unit
Award Agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of
separate Restricted Stock Unit Award Agreements need not be identical, provided, however, that each Restricted Stock Unit Award Agreement shall conform to (through incorporation of the provisions hereof by reference in the Agreement or
otherwise) the substance of each of the following provisions: 
 (i) Consideration. At the time of grant of a
Restricted Stock Unit Award, the Board will determine the consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the
Participant for each share of Common Stock subject to a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Board in its sole discretion and permissible under applicable law. 

(ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions or conditions to
the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 
 (iii) Payment. A
Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award
Agreement. 
 (iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Board, as it
deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award.

 (v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Common Stock covered by a Restricted
Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into additional shares of Common Stock covered by the Restricted
Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all the terms and conditions of the underlying Restricted
Stock Unit Award Agreement to which they relate. 
 (vi) Termination of Participant’s Continuous
Service. Except as otherwise provided in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous
Service.  
 (vii) Compliance with Section 409A of the Code. Notwithstanding anything to the
contrary set forth herein, any Restricted Stock Unit Award granted under the Plan that is not exempt from the requirements of Section 409A of the Code shall contain such provisions so that such Restricted Stock Unit Award will comply with the

 7. COVENANTS OF THE COMPANY. 

(a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of
shares of Common Stock reasonably required to satisfy such Stock Awards. 
 (b) Securities Law Compliance. The Company shall
seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided,
however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is
unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure
to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant shall not be eligible for the grant of a Stock Award or the subsequent issuance of Common Stock pursuant to the Stock Award
if such grant or issuance would be in violation of any applicable securities law. 
 (c) No Obligation to Notify. The Company
shall have no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Stock Award. Furthermore, the Company shall have no duty or obligation to warn or otherwise advise such holder of a pending
termination or expiration of a Stock Award or a possible period in which the Stock Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of a Stock Award to the holder of such Stock Award. 

8. MISCELLANEOUS. 

(a) Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Stock Awards shall
constitute general funds of the Company. 
 (b) Corporate Action Constituting Grant of Stock Awards. Corporate action
constituting a grant by the Company of a Stock Award to any Participant shall be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing
the Stock Award is communicated to, or actually received or accepted by, the Participant. 
 (c) Stockholder Rights. No
Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Stock Award unless and until (i) such Participant has satisfied all requirements for exercise
of the Stock Award pursuant to its terms, if applicable, and (ii) the issuance of the Common Stock subject to such Stock Award has been entered into the books and records of the Company. 

  
 12. 

 (d) No Employment or Other Service Rights. Nothing in the Plan, any Stock
Award Agreement or any other instrument executed thereunder or in connection with any Stock Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the
time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the
terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the
Company or the Affiliate is incorporated, as the case may be. 
 (e) Incentive Stock Option $100,000 Limitation. To the extent
that the aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and
any Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options, notwithstanding any
contrary provision of the applicable Option Agreement(s). 
 (f) Investment Assurances. The Company may require a Participant,
as a condition of exercising or acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and
risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any
present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (x) the issuance of the shares upon the exercise or acquisition
of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act, or (y) as to any particular requirement, a determination is made by counsel for the Company that such
requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 

(g) Withholding Obligations. Unless prohibited by the terms of a Stock Award Agreement, the Company may, in its sole discretion,
satisfy any federal, state or local tax withholding obligation relating to a Stock Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of
Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Stock Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax
required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding payment from any amounts otherwise payable to the
Participant; (iv) withholding cash from a Stock Award settled in cash; or (v) by such other method as may be set forth in the Stock Award Agreement. 

  
 13. 

 (h) Electronic Delivery. Any reference herein to a “written”
agreement or document shall include any agreement or document delivered electronically or posted on the Company’s intranet. 

(i) Deferrals. To the extent permitted by applicable law, the Board, in its sole discretion, may determine that the delivery of
Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Stock Award may be deferred and may establish programs and procedures for deferral elections to be made by Participants. Deferrals by
Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is still an employee or otherwise providing services to the
Company. The Board is authorized to make deferrals of Stock Awards and determine when, and in what annual percentages, Participants may receive payments, including lump sum payments, following the Participant’s termination of Continuous
Service, and implement such other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law. 

(j) Compliance with Section 409A. To the extent that the Board determines that any Stock Award granted
hereunder is subject to Section 409A of the Code, the Stock Award Agreement evidencing such Stock Award shall incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code. To the
extent applicable, the Plan and Stock Award Agreements shall be interpreted in accordance with Section 409A of the Code. 
 (k)
Compliance with Exemption Provided by Rule 12h-1(f). If: (i) the aggregate of the number of Optionholders and the number of holders of all other outstanding compensatory employee stock options to
purchase shares of Common Stock equals or exceeds five hundred (500), and (ii) the assets of the Company at the end of the Company’s most recently completed fiscal year exceed $10 million, then the following restrictions
shall apply during any period during which the Company does not have a class of its securities registered under Section 12 of the Exchange Act and is not required to file reports under Section 15(d) of the Exchange Act: (A) the
Options and, prior to exercise, the shares of Common Stock acquired upon exercise of the Options may not be transferred until the Company is no longer relying on the exemption provided by Rule 12h-1(f)
promulgated under the Exchange Act (“Rule 12h-1(f)”), except: (1) as permitted by Rule 701(c) promulgated under the Securities
Act, (2) to a guardian upon the disability of the Optionholder, or (3) to an executor upon the death of the Optionholder (collectively, the “Permitted Transferees”); provided,
however, the following transfers are permitted: (i) transfers by the Optionholder to the Company, and (ii) transfers in connection with a change of control or other acquisition involving the Company, if following such transaction, the
Options no longer remain outstanding and the Company is no longer relying on the exemption provided by Rule 12h-1(f); provided further, that any Permitted Transferees may not further transfer the
Options; (B) except as otherwise provided in (A) above, the Options and shares of Common Stock acquired upon exercise of the Options are restricted as to any pledge, hypothecation, or other transfer, including any short position, any
“put equivalent position” as defined by Rule 16a-1(h) promulgated under the Exchange Act, or any “call equivalent position” as defined by
Rule 16a-1(b) promulgated under the Exchange Act by the Optionholder prior to exercise of an Option until the Company is no longer relying on the exemption provided by
Rule 12h-1(f); and (C) at any time that the Company is relying on the exemption provided by Rule 12h-1(f), the

  
 14. 

 
Company shall deliver to Optionholders (whether by physical or electronic delivery or written notice of the availability of the information on an internet site) the information required by
Rule 701(e)(3), (4), and (5) promulgated under the Securities Act every six (6) months, including financial statements that are not more than one hundred eighty (180) days old; provided, however, that the
Company may condition the delivery of such information upon the Optionholder’s agreement to maintain its confidentiality. 
 (l)
Repurchase Limitation. The terms of any repurchase right shall be specified in the Stock Award Agreement. The repurchase price for vested shares of Common Stock shall be the Fair Market Value of the shares of Common Stock on the date of
repurchase. The repurchase price for unvested shares of Common Stock shall be the lower of (i) the Fair Market Value of the shares of Common Stock on the date of repurchase or (ii) their original purchase price. However, the Company shall
not exercise its repurchase right until at least six (6) months (or such longer or shorter period of time necessary to avoid classification of the Stock Award as a liability for financial accounting purposes) have elapsed following
delivery of shares of Common Stock subject to the Stock Award, unless otherwise specifically provided by the Board. 
 9. ADJUSTMENTS
UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS. 

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board shall appropriately and proportionately
adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 0, (ii) the class(es) and maximum number of securities that may be issued pursuant to the exercise of Incentive Stock Options pursuant
to Section 0, and (iii) the class(es) and number of securities and price per share of stock subject to outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. 

(b) Dissolution or Liquidation. Except as otherwise provided in the Stock Award Agreement, in the event of a dissolution or
liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) shall terminate
immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company
notwithstanding the fact that the holder of such Stock Award is providing Continuous Service, provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become fully vested, exercisable and/or no longer
subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion. 

(c) Corporate Transaction. The following provisions shall apply to Stock Awards in the event of a Corporate Transaction unless
otherwise provided in the instrument evidencing the Stock Award or any other written agreement between the Company or any Affiliate and the holder of the Stock Award or unless otherwise expressly provided by the Board at the time of grant of a Stock
Award. Except as otherwise stated in the Stock Award Agreement, in the event of a Corporate Transaction, then, notwithstanding any other provision of the Plan, the Board shall take one or more of the following actions with respect to Stock Awards,
contingent upon the closing or completion of the Corporate Transaction: 

  
 15. 

 (i) arrange for the surviving corporation or acquiring corporation (or the surviving
or acquiring corporation’s parent company) to assume or continue the Stock Award or to substitute a similar stock award for the Stock Award (including, but not limited to, an award to acquire the same consideration paid to the stockholders of
the Company pursuant to the Corporate Transaction); 
 (ii) arrange for the assignment of any reacquisition or repurchase rights held
by the Company in respect of Common Stock issued pursuant to the Stock Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company); 

(iii) accelerate the vesting, in whole or in part, of the Stock Award (and, if applicable, the time at which the Stock Award may be
exercised) to a date prior to the effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective date of the Corporate
Transaction), with such Stock Award terminating if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction; 

(iv) arrange for the lapse of any reacquisition or repurchase rights held by the Company with respect to the Stock Award; 

(v) cancel or arrange for the cancellation of the Stock Award, to the extent not vested or not exercised prior to the effective time of
the Corporate Transaction, in exchange for such cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and 

(vi) make a payment, in such form as may be determined by the Board equal to the excess, if any, of (A) the value of the property
the holder of the Stock Award would have received upon the exercise of the Stock Award, over (B) any exercise price payable by such holder in connection with such exercise. 

The Board need not take the same action with respect to all Stock Awards or with respect to all Participants. 

(d) Change in Control. A Stock Award may be subject to additional acceleration of vesting and exercisability upon or after a
Change in Control as may be provided in the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such
acceleration shall occur. 
 10. TERMINATION OR SUSPENSION OF THE

by the Board pursuant to Section 2, the Plan shall automatically terminate on the day before the tenth (10th) anniversary of the earlier of (i) the date the Plan is adopted by the Board, or (ii) the date the Plan is approved by
the stockholders of the Company. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated.

impair rights and obligations under any Stock Award granted while the Plan is in effect except with the written consent of the affected Participant.

Capitalization Adjustment.

written agreement between the Participant and the Company defining such term and, in the absence of such agreement, such term means with respect to a Participant, the occurrence of any of the following events: (i) such

of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company
through the issuance of equity securities or (C) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding
voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result
of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the

Control shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written

an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director, or Consultant or a change in the Entity for which the
Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, shall not terminate a Participant’s Continuous Service; provided, however, if the
Entity for which a Participant is rendering service ceases to qualify as an Affiliate, as determined by the Board in its sole discretion, such Participant’s Continuous Service shall be considered to have terminated on the date such Entity
ceases to qualify as an Affiliate. For example, a change in status from an employee of the Company to a consultant of an Affiliate or to a Director shall not constitute an interruption of Continuous Service. To the extent permitted by law, the Board
or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service shall be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive
officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence shall be treated as Continuous Service for

OPTION AGREEMENT 

 NURIX THERAPEUTICS, INC. 

2012 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,
Nurix Therapeutics, Inc. (the “Company”) has granted you an option under its 2012 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 “Early Exercise 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 unvested 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. 
 (c) Pursuant to the following deferred payment alternative: 

(i) Not less than one hundred percent (100%) of the aggregate exercise price, plus accrued interest, shall be due four (4) years
from date of exercise or, at the Company’s election, upon termination of your Continuous Service. 
 (ii) Interest shall be
compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid (1) the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the
deferred payment arrangement and (2) the classification of your option as a liability for financial accounting purposes. 

(iii) In order to elect the deferred payment alternative, you must, as a part of your written notice of exercise, give notice of the
election of this payment alternative and, in order to secure the payment of the deferred exercise price to the Company hereunder, if the Company so requests, you must tender to the Company a promissory note and a pledge agreement covering the
purchased shares of Common Stock, both in form and substance satisfactory to the Company, or such other or additional documentation as the Company may request. 

  
 2. 

 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. 

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 during your Continuous Service; 

(d) the Expiration Date indicated in your Grant Notice; or 

(e) the day before the tenth (10th) anniversary of the Date of Grant. 

Notwithstanding the foregoing, if you die during the period provided in Section 8(a) or 8(b) above, the term of your option shall not
expire until the earlier of eighteen (18) months after your death, the Expiration Date indicated in your Grant Notice, or 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 Disability. 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. 

  
 3. 

 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. 

(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 or NYSE Member
Rule 472 and similar 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. 

(e) By exercising your option, you agree to be bound by the provisions of, and execute a counterpart signature to, the (i) Voting
Agreement entered into by the Company, the holders of the Company’s Preferred Stock and the Key Holders (as defined therein) as such agreement may be amended from time to time (the “Voting Agreement”) and (ii) Right
of First Refusal and Co-Sale Agreement entered into by the Company, the holders of the Company’s Preferred Stock and the Key Holders (as defined therein) as such agreement may be amended from time to time
(the “Co-Sale Agreement”), and to be deemed a “Key Holder” under the Voting Agreement and Co-Sale Agreement for purposes thereof.
Copies of the Voting Agreement and Co-Sale Agreement are available for your inspection upon request. 

  
 4. 

 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 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. 
 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. 

  
 5. 

 (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. TAX
CONSEQUENCES. You hereby agree that the Company does not have a duty to design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You shall not make any claim
against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the
Code only if the exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated
with the option. Because the Common Stock is not traded on an established securities market, the Fair Market Value is determined by the Board, perhaps in consultation with an independent valuation firm retained by the Company. You acknowledge that
there is no guarantee that the Internal Revenue Service will agree with the valuation as determined by the Board, and you shall not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that the
Internal Revenue Service asserts that the valuation determined by the Board is less than the “fair market value” as subsequently determined by the Internal Revenue Service. 

16. 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. 

  
 6. 

 17. 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.

EARLY EXERCISE STOCK PURCHASE AGREEMENT UNDER
THE 
 2012 EQUITY INCENTIVE PLAN 

THIS AGREEMENT is made by and between Nurix Therapeutics, Inc., a Delaware
corporation (the “Company”), and _______________ (“Purchaser”). 

WITNESSETH: 

WHEREAS, Purchaser holds a stock option
dated                         to purchase shares of common stock (“Common Stock”) of the Company
(the “Option”) pursuant to the Company’s 2012 Equity Incentive Plan (the “Plan”); and 

WHEREAS, the Option consists of a Stock Option Grant Notice and a Stock Option Agreement; and 

WHEREAS, Purchaser desires to exercise the Option on the terms and conditions contained herein; and 

WHEREAS, Purchaser wishes to take advantage of the early exercise provision of Purchaser’s Option and therefore to
enter into this Agreement; 
 NOW, THEREFORE, IT IS
AGREED between the parties as follows: 
 1. INCORPORATION OF
PLAN AND OPTION BY REFERENCE. This Agreement is subject to all of the terms and conditions as set forth in the Plan and the Option. If there is a conflict between the
terms of this Agreement and/or the Option and the terms of the Plan, the terms of the Plan shall control. If there is a conflict between the terms of this Agreement and the terms of the Option, the terms of the Option shall control. Defined terms
not explicitly defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan. Defined terms not explicitly defined in this Agreement or the Plan but defined in the Option shall have the same definitions as in the
Option. 
 2. PURCHASE AND SALE OF COMMON
STOCK. 
 (a) Agreement to purchase and sell Common Stock. Purchaser hereby agrees to purchase from
the Company, and the Company hereby agrees to sell to Purchaser, shares of the Common Stock of the Company in accordance with the Notice of Exercise duly executed by Purchaser and attached hereto as Exhibit A. 

(b) Closing. The closing hereunder, including payment for and delivery of the Common Stock, shall occur at the offices of the
Company immediately following the execution of this Agreement, or at such other time and place as the parties may mutually agree; provided, however, that if stockholder approval of the Plan is required before the Option may be exercised, then
the Option may not be exercised, and the closing shall be delayed, until such stockholder approval is obtained. If such stockholder approval is not obtained within the time limit specified in the Plan, then this Agreement shall be null and void.

  
 1. 

 3. UNVESTED SHARE REPURCHASE
OPTION. 
 (a) Repurchase Option. In the event Purchaser’s Continuous Service terminates, then the
Company shall have an irrevocable option (the “Repurchase Option”) for a period of six (6) months after said termination (or in the case of shares issued upon exercise of the Option after such date of termination, within
six (6) months after the date of the exercise), or such longer period as may be agreed to by the Company and Purchaser, to repurchase from Purchaser or Purchaser’s personal representative, as the case may be, those shares that Purchaser
received pursuant to the exercise of the Option that have not as yet vested as of such termination date in accordance with the Vesting Schedule indicated on Purchaser’s Stock Option Grant Notice (the “Unvested
Shares”). 
 (b) Share Repurchase Price. The Company may repurchase all or any of the Unvested Shares at
the lower of (i) the Fair Market Value of the such shares (as determined under the Plan) on the date of repurchase, or (ii) the price equal to Purchaser’s Exercise Price for such shares as indicated on Purchaser’s Stock
Option Grant Notice. 
 4. EXERCISE OF REPURCHASE
OPTION. If the Company elects to exercise the Repurchase Option, it shall be exercised by written notice signed by such person as designated by the Company, and delivered or mailed as provided herein.
Such notice shall identify the number of shares of Common Stock to be purchased and shall notify Purchaser of the time, place and date for settlement of such purchase, which shall be scheduled by the Company within the term of the Repurchase Option
set forth above. The Company shall be entitled to pay for any shares of Common Stock purchased pursuant to its Repurchase Option at the Company’s option in cash or by offset against any indebtedness owing to the Company by Purchaser (including
without limitation any Promissory Note given in payment for the Common Stock), or by a combination of both. Upon delivery of such notice and payment of the purchase price in any of the ways described above, the Company shall become the legal and
beneficial owner of the Common Stock being repurchased and all rights and interest therein or related thereto, and the Company shall have the right to transfer to its own name the Common Stock being repurchased by the Company, without further action
by Purchaser. 
 5. CAPITALIZATION ADJUSTMENTS TO COMMON
STOCK. In the event of a Capitalization Adjustment, then any and all new, substituted or additional securities or other property to which Purchaser is entitled by reason of Purchaser’s ownership of Common Stock shall
be immediately subject to the Repurchase Option and be included in the word “Common Stock” for all purposes of the Repurchase Option with the same force and effect as the shares of the Common Stock presently subject to the Repurchase
Option, but only to the extent the Common Stock is, at the time, covered by such Repurchase Option. While the total Option Price shall remain the same after each such event, the Option Price per share of Common Stock upon exercise of the Repurchase
Option shall be appropriately adjusted. 

  
 2. 

 6. CORPORATE TRANSACTIONS. In the event of a
Corporate Transaction, then the Repurchase Option may be assigned by the Company to the successor of the Company (or such successor’s parent company), if any, in connection with such Corporate Transaction. To the extent the Repurchase Option
remains in effect following such Corporate Transaction, it shall apply to the new capital stock or other property received in exchange for the Common Stock in consummation of the Corporate Transaction, but only to the extent the Common Stock was at
the time covered by such right. Appropriate adjustments shall be made to the price per share payable upon exercise of the Repurchase Option to reflect the Corporate Transaction upon the Company’s capital structure; provided, however,
that the aggregate price payable upon exercise of the Repurchase Option shall remain the same. 
 7. ESCROW
OF UNVESTED COMMON STOCK. As security for Purchaser’s faithful performance of the terms of this Agreement and to insure the availability for delivery
of Purchaser’s Common Stock upon exercise of the Repurchase Option herein provided for, Purchaser agrees, at the closing hereunder, to deliver to and deposit with the Secretary of the Company or the Secretary’s designee (“Escrow
Agent”), as Escrow Agent in this transaction, three (3) stock assignments duly endorsed (with date and number of shares blank) in the form attached hereto as Exhibit B, together with a certificate or certificates evidencing
all of the Common Stock subject to the Repurchase Option; said documents are to be held by the Escrow Agent and delivered by said Escrow Agent pursuant to the Joint Escrow Instructions of the Company and Purchaser set forth in Exhibit C,
attached hereto and incorporated by this reference, which instructions also shall be delivered to the Escrow Agent at the closing hereunder. 

8. RIGHTS OF PURCHASER. Subject to the provisions of
the Option, Purchaser shall exercise all rights and privileges of a stockholder of the Company with respect to the shares deposited in escrow. Purchaser shall be deemed to be the holder of the shares for purposes of receiving any dividends that may
be paid with respect to such shares and for purposes of exercising any voting rights relating to such shares, even if some or all of such shares have not yet vested and been released from the Company’s Repurchase Option. 

9. LIMITATIONS ON TRANSFER. In addition to any other
limitation on transfer created by applicable securities laws, Purchaser shall not sell, assign, hypothecate, donate, encumber or otherwise dispose of any interest in the Common Stock while the Common Stock is subject to the Repurchase Option. After
any Common Stock has been released from the Repurchase Option, Purchaser shall not sell, assign, hypothecate, donate, encumber or otherwise dispose of any interest in the Common Stock except in compliance with the provisions herein and applicable
securities laws. Furthermore, the Common Stock shall be subject to any right of first refusal in favor of the Company or its assignees that may be contained in the Company’s Bylaws. 

10. RESTRICTIVE LEGENDS. All certificates representing the Common
Stock shall have endorsed thereon legends in substantially the following forms (in addition to any other legend which may be required by other agreements between the parties hereto): 

(a) “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO AN OPTION SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE
REGISTERED HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS COMPANY. ANY TRANSFER OR ATTEMPTED TRANSFER OF ANY SHARES SUBJECT TO SUCH OPTION IS VOID WITHOUT THE PRIOR EXPRESS WRITTEN
CONSENT OF THE COMPANY.” 

  
 3. 

 (b) “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933 AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY
THAT SUCH REGISTRATION IS NOT REQUIRED.” 
 (c) “THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED PURSUANT TO THE
EXERCISE OF AN INCENTIVE STOCK OPTION.” 
 (d) Any legend required by appropriate blue sky officials. 

11. INVESTMENT REPRESENTATIONS. In connection with the purchase of the Common Stock, Purchaser
represents to the Company the following: 
 (a) Purchaser is aware of the Company’s business affairs and financial condition and
has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Common Stock. Purchaser is acquiring the Common Stock for investment for Purchaser’s own account only and not with a view to,
or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act. 
 (b) Purchaser
understands that the Common Stock has not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed
herein. 
 (c) Purchaser further acknowledges and understands that the Common Stock must be held indefinitely unless the Common Stock
is subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the Company is under no obligation to register the Common Stock. Purchaser understands that
the certificate evidencing the Common Stock will be imprinted with a legend that prohibits the transfer of the Common Stock unless the Common Stock is registered or such registration is not required in the opinion of counsel for the Company. 

(d) Purchaser is familiar with the provisions of Rules 144 and 701, under the Securities Act, as in effect from time to time,
which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof (or from an affiliate of such issuer), in a non-public offering
subject to the satisfaction of certain conditions. Rule 701 provides that if the issuer qualifies under Rule 701 at the time of issuance of the securities, such issuance will be exempt from registration under the Securities Act. In the event the
Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the securities exempt under Rule 701 may be sold by Purchaser ninety (90) days thereafter, subject to the
satisfaction of certain of the conditions specified by Rule 144 and the market stand-off provision described in Purchaser’s Stock Option Agreement. 

(e) In the event that the sale of the Common Stock does not qualify under Rule 701 at the time of purchase, then the Common Stock
may be resold by Purchaser in certain limited circumstances subject to the provisions of Rule 144, which requires, among other things: 

  
 4. 

 
(i) the availability of certain public information about the Company, and (ii) the resale occurring following the required holding period under Rule 144 after Purchaser has purchased, and
made full payment of (within the meaning of Rule 144), the securities to be sold. 
 (f) Purchaser further understands that at the
time Purchaser wishes to sell the Common Stock there may be no public market upon which to make such a sale, and that, even if such a public market then exists, the Company may not be satisfying the current public current information requirements of
Rule 144 or 701, and that, in such event, Purchaser would be precluded from selling the Common Stock under Rule 144 or 701 even if the minimum holding period requirement had been satisfied. 

12. MARKET STAND-OFF AGREEMENT.
By exercising the Option, Purchaser agrees not to 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 Purchaser, 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 or NYSE Member Rule 472 and similar rules or regulations (the “Lock-Up Period”); provided, however, that nothing shall prevent
the exercise of the Repurchase Option during the Lock-Up Period. Purchaser further agrees 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 Purchaser’s 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 12 and shall have the right, power and authority to enforce the provisions hereof as though they were a party
hereto. 
 13. SECTION 83(b) ELECTION. Purchaser understands that
Section 83(a) of the Code taxes as ordinary income the difference between the amount paid for the Common Stock and the fair market value of the Common Stock as of the date any restrictions on the Common Stock lapse. In this context,
“restriction” includes the right of the Company to buy back the Common Stock pursuant to the Repurchase Option set forth above. Purchaser understands that Purchaser may elect to be taxed at the time the Common Stock is purchased, rather
than when and as the Repurchase Option expires, by filing an election under Section 83(b) (an “83(b) Election”) of the Code with the Internal Revenue Service within thirty (30) days of the date of purchase. Even if
the fair market value of the Common Stock at the time of the execution of this Agreement equals the amount paid for the Common Stock, the 83(b) Election must be made to avoid income under Section 83(a) in the future. Purchaser understands that
failure to file such an 83(b) Election in a timely manner may result in adverse tax consequences for Purchaser. Purchaser acknowledges that the foregoing is only a summary of the effect of United States federal income taxation with respect to
purchase of the Common Stock hereunder, and does not purport to be complete. Purchaser further acknowledges that the Company has directed Purchaser to seek independent advice regarding the applicable provisions of the Code, the income tax laws of
any municipality, state or foreign country in which Purchaser may reside, and the tax consequences of Purchaser’s death. Purchaser assumes all responsibility for filing an 83(b) Election and paying all taxes resulting from such election or the
lapse of the restrictions on the Common Stock. 

  
 5. 

 14. REFUSAL TO
TRANSFER. The Company shall not be required (a) to transfer on its books any shares of Common Stock of the Company which shall have been transferred in violation of any of the provisions set forth
in this Agreement, or (b) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares shall have been so transferred. 

15. NO EMPLOYMENT RIGHTS. This Agreement is not an
employment contract and nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company or its Affiliates to terminate Purchaser’s employment for any reason at any time, with or without cause and with or
without notice. 
 16. MISCELLANEOUS. 

(a) Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given:
(a) upon personal delivery to the party to be notified, (b) when sent by confirmed facsimile if sent during normal business hours of the recipient, and if not during normal business hours of the recipient, then on the next business day,
(c) five (5) calendar days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) business day after deposit with a nationally recognized overnight courier, specifying
next day delivery, with written verification of receipt. All communications shall be sent to the other party hereto at such party’s address hereinafter set forth on the signature page hereof, or at such other address as such party may designate
by ten (10) days advance written notice to the other party hereto. 
 (b)Successors and Assigns. This Agreement shall
inure to the benefit of the successors and assigns of the Company and, subject to the restrictions on transfer herein set forth, be binding upon Purchaser, Purchaser’s successors, and assigns. The Company may assign the Repurchase Option
hereunder at any time or from time to time, in whole or in part. 
 (c) Attorneys’ Fees; Specific Performance. Purchaser
shall reimburse the Company for all costs incurred by the Company in enforcing the performance of, or protecting its rights under, any part of this Agreement, including reasonable costs of investigation and attorneys’ fees. It is the intention
of the parties that the Company, upon exercise of the Repurchase Option and payment for the shares repurchased, pursuant to the terms of this Agreement, shall be entitled to receive the Common Stock, in specie, in order to have such Common
Stock available for future issuance without dilution of the holdings of other stockholders. Furthermore, it is expressly agreed between the parties that money damages are inadequate to compensate the Company for the Common Stock and that the Company
shall, upon proper exercise of the Repurchase Option, be entitled to specific enforcement of its rights to purchase and receive said Common Stock. 

(d) Governing Law; Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of
California. The parties agree that any action brought by either party to interpret or enforce any provision of this Agreement shall be brought in, and each party agrees to, and does hereby, submit to the jurisdiction and venue of, the appropriate
state or federal court for the district encompassing the Company’s principal place of business. 

  
 6. 

 (e) Further Execution. The parties agree to take all such further action(s) as
may reasonably be necessary to carry out and consummate this Agreement as soon as practicable, and to take whatever steps may be necessary to obtain any governmental approval in connection with or otherwise qualify the issuance of the securities
that are the subject of this Agreement. 
 (f) Independent Counsel. Purchaser acknowledges that this Agreement has been
prepared on behalf of the Company by Fenwick & West LLP, counsel to the Company and that Fenwick & West LLP does not represent, and is not acting on behalf of, Purchaser. Purchaser has been provided with an opportunity to consult
with Purchaser’s own counsel with respect to this Agreement. 
 (g) Entire Agreement; Amendment. This Agreement
constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes and merges all prior agreements or understandings, whether written or oral. This Agreement may not be amended, modified or revoked, in
whole or in part, except by an agreement in writing signed by each of the parties hereto. 
 (h) Severability. If one or more
provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such
provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in
accordance with its terms. 
 (i) Counterparts. This Agreement may be executed in two or more counterparts, each of which
shall be deemed an original and all of which together shall constitute one instrument. 
 IN WITNESS
WHEREOF, the parties hereto have executed this Agreement as of _______________.

 1.    Lease of Premises. Upon and subject to all of the terms and conditions
hereof, Landlord hereby leases the Premises to Tenant and Tenant hereby leases the Premises from Landlord. The portions of the Project which are for the non-exclusive use of tenants of the Project are
collectively referred to herein as the “Common Areas.” Tenant shall have the non-exclusive use of the Common Areas in common with other tenants of the Project. Landlord reserves the right to
modify Common Areas, provided that such modifications do not materially adversely affect Tenant’s use of the Premises for the Permitted Use and provided that such modifications do not materially increase the obligations or decrease the rights
of Tenant under this Lease. 
 2.    Delivery; Acceptance of Premises; Commencement Date. 

(a)    Prior Premises and First Initial Premises. Landlord shall use reasonable efforts to deliver
(“Delivery” or “Deliver”) the First Initial Premises to Tenant on or before the Target Initial Premises Commencement Date with the Phase 1 Landlord’s Work Substantially Completed. If Landlord fails to timely
Deliver the First Initial Premises, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and this Lease shall not be void or voidable except as provided herein. If Landlord does not Deliver the First Initial Premises to
Tenant within 90 days of the Target First Initial Premises Commencement Date for any reason other than Force Majeure delays or Tenant Delays, this Lease may be terminated by Tenant by written notice to Landlord, and if so terminated by Tenant,
neither Landlord nor Tenant shall have any further rights, duties or obligations under this Lease, except with respect to provisions which expressly survive the termination of this Lease. If Tenant does not elect to void this Lease within
5 business days of the lapse of such 90 day period, such right to void this Lease shall be waived and this Lease shall remain in full force and effect. As used in this Section 2(a), the terms “Phase 1
Landlord’s Work,” “Tenant Delays” “Substantially Completed” shall have the meanings set forth for such terms in the Work Letter. 

The “First Initial Premises Commencement Date” shall be the earlier of (i) the date Landlord Delivers the First
Initial Premises to Tenant in vacant (except only for the Tenant’s Property listed on Exhibit F as “Presidio Property” located within the First Initial Premises), broom-clean condition with the Phase 1
Landlord’s Work Substantially Completed, or (ii) the date Landlord could have Delivered the First Initial Premises with the Phase 1 Landlord’s Work Substantially Completed but for Tenant Delays. For the avoidance of doubt, Landlord
shall remove its old workstation frames located in the First Initial Premises prior to the First Initial Premises Commencement Date. The “Month-to-Month Premises
Rent Commencement Date” shall be the date that is 30 days after the First Initial Premises Commencement Date. Tenant shall commence paying Month-to-Month Base
Rent for the Prior Premises and the First Expansion Premises on the Month-to-Month Premises Rent Commencement Date. 

Landlord and Tenant acknowledge that Tenant occupied the Prior Premises prior to the First Initial Premises Commencement Date pursuant to that
certain Lease Agreement between Landlord and Tenant dated as of March 30, 2012 (as the same has been or may in the future be amended, the “Prior Lease”). 

For the period of 60 consecutive days after the First Initial Premises Commencement Date, Landlord shall, at its sole cost and expense (which
shall not constitute an Operating Expense), be responsible for any repairs that are required to be made to the Building Systems (as defined in Section 13) serving the First Initial Premises, unless Tenant or any Tenant
Party was responsible for the cause of such repair, in which case Tenant shall pay the cost. 

  
 3 

 Except as otherwise provided in this Lease or in the Work Letter: (i) Landlord shall
have no obligation for any defects in the Prior Premises; (ii) Tenant’s occupancy of the Prior Premises pursuant to the terms of the Prior Lease shall be conclusive evidence that the Prior Premises are in good condition as of the First
Initial Premises Commencement Date; (iii) Tenant shall accept the First Initial Premises in their condition as of the First Initial Premises Commencement Date, subject to all applicable Legal Requirements (as defined in
Section 7 hereof); (iv) Landlord shall have no obligation for any defects in the First Initial Premises; and (v) Tenant’s taking possession of the First Initial Premises shall be conclusive evidence that Tenant
accepts the First Initial Premises and that the First Initial Premises were in good condition at the time possession was taken. 

(b)    Second Initial Premises. Landlord shall use reasonable efforts to Deliver the Second Initial Premises to
Tenant on or before the Target Second Initial Premises Commencement Date with the Phase 2 Landlord’s Work Substantially Completed. If Landlord fails to timely Deliver the Second Initial Premises, Landlord shall not be liable to Tenant for any
loss or damage resulting therefrom, and this Lease shall not be void or voidable except as provided herein. If Landlord does not Deliver the Second Initial Premises to Tenant within 90 days of the Target Second Initial Premises Commencement Date for
any reason other than Force Majeure delays or Tenant Delays, this Lease may be terminated by Tenant by written notice to Landlord, and if so terminated by Tenant, neither Landlord nor Tenant shall have any further rights, duties or obligations under
this Lease, except with respect to provisions which expressly survive the termination of this Lease. If Tenant does not elect to void this Lease within 5 business days of the lapse of such 90 day period, such right to void this Lease shall be waived
and this Lease shall remain in full force and effect. As used in this Section 2(b), the terms “Phase 2 Landlord’s Work,” “Tenant Delays” and “Substantially Completed”
shall have the meanings set forth for such terms in the Work Letter. 
 The “Second Initial Premises Commencement
Date” shall be the earlier of (i) the date Landlord Delivers the Second Initial Premises to Tenant in vacant (except only for the Presidio Property located within the Second Initial Premises), broom clean condition with the Phase 2
Landlord’s Work Substantially Completed, or (ii) the date Landlord could have Delivered the Second Initial Premises with the Phase 2 Landlord’s Work Substantially Completed but for Tenant Delays. Tenant shall commence paying Base Rent
with respect to the Second Initial Premises on the Second Initial Premises Commencement Date. 
 Subject to the provisions of
Section 6 of the Work Letter, Landlord shall permit Tenant access to the Second Initial Premises for a period of 10 days prior to the Second Initial Premises Commencement Date for Tenant’s installation and setup of
furniture, fixtures and equipment (“FF&E Installation”) in the Second Initial Premises, provided that such FF&E Installation is coordinated with Landlord, and Tenant complies with the Lease and all other reasonable
restrictions and conditions Landlord may impose. All such access shall be during normal business hours. Any access to the Second Initial Premises by Tenant before the Second Initial Premises Commencement Date shall be subject to all of the terms and
conditions of this Lease, excluding the obligation to pay Base Rent or Operating Expenses. 
 If, during the period that Landlord is
performing the Phase 2 Landlord’s Work (as defined in the Work Letter) pursuant to the Work Letter, there are portions of the Second Initial Premises in which Landlord’s Work is not being performed, Landlord shall, subject to third
sentence of this paragraph, allow Tenant to occupy and conduct business in all or any such portions of the Second Initial Premises (the “Second Initial Premises Early Occupancy Space”). If Tenant occupies any Second Initial Premises
Early Occupancy Space, the rentable square footage of such Second Initial Premises Early Occupancy Space shall be added to and be included under this Lease as part of the
Month-to-Month Premises commencing on the date that Tenant commences occupying such Second Initial Premises Early Occupancy Space. Notwithstanding anything to the
contrary contained herein, Landlord shall have the right to exclude Tenant and any Tenant Parties from all or any portion of the Second Initial Premises Early Occupancy Space until Substantial Completion of the Phase 2 Landlord’s Work if any
such occupancy interferes, in Landlord’s reasonable discretion, with the performance of the Phase 2 Landlord’s Work. If Landlord determines that Second Initial Premises Early Occupancy Space is available and Tenant desires to operate in
such Second Initial Premises Early Occupancy Space, Landlord and Tenant shall enter into an amendment of this Lease in a form acceptable to Landlord and Tenant each in their reasonable discretion, providing for the expansion of the Month-to-Month Premises to include such Second Initial Premises Early Occupancy Space pursuant to the terms of this paragraph, 

  
 4 

 For the period of 60 consecutive days after the Second Initial Premises Commencement Date,
Landlord shall, at its sole cost and expense (which shall not constitute an Operating Expense), be responsible for any repairs that are required to be made to the Building Systems (as defined in Section 13) serving the
Second Initial Premises, unless Tenant or any Tenant Party was responsible for the cause of such repair, in which case Tenant shall pay the cost. 

Except as otherwise provided in this Lease or the Work Letter: (i) Tenant shall accept the Second Initial Premises in their condition as
of the Second Initial Premises Commencement Date, subject to all applicable Legal Requirements; (ii) Landlord shall have no obligation for any defects in the Second Initial Premises; and (iii) Tenant’s taking possession of the Second
Initial Premises shall be conclusive evidence that Tenant accepts the Second Initial Premises and that the Second Initial Premises were in good condition at the time possession was taken. 

(c)    Subsequent Premises. Landlord shall use reasonable efforts to Deliver the Subsequent Premises to Tenant on
or before the Target Subsequent Premises Commencement Date, with any portion of the Phase 3 Landlord’s Work being performed in the Subsequent Premises, if any, Substantially Completed. If Landlord fails to timely Deliver the Subsequent Premises
with Phase 3 Landlord’s Work in the Subsequent Premises, in any, Substantially Completed, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and this Lease shall not be void or voidable except as provided herein.
If Landlord does not (i) Deliver the Subsequent Premises, with any portion of the Phase 3 Landlord’s Work being performed in the Subsequent Premises, if any, Substantially Completed, and (ii) Substantially Complete the Phase 3 Work
being performed in the Long-Term Premises, within 90 days of the Target Subsequent Premises Commencement Date for any reason other than Force Majeure delays and Tenant Delays, this Lease may be terminated by Tenant by written notice to Landlord, and
if so terminated by Tenant: (a) the Security Deposit, or any balance thereof (i.e., after deducting therefrom all amounts to which Landlord is entitled under the provisions of this Lease), shall be returned to Tenant, and (b) neither
Landlord nor Tenant shall have any further rights, duties or obligations under this Lease, except with respect to provisions which expressly survive termination of this Lease. Notwithstanding anything to the contrary contained herein, if Tenant
terminates this Lease pursuant to the immediately preceding sentence, Tenant may elect, by delivery of written notice to Landlord concurrently with Tenant’s delivery of written notice to Landlord terminating this Lease pursuant to the
immediately preceding sentence, to extend the Term of the Lease with respect to the Month-to-Month Premises only for a period of up to 6 months; provided, however, that
Tenant shall have the right prior to the end of such 6-month period to terminate such extended Term with respect to the
Month-to-Month Premises upon 30 days written notice to Landlord. As used in this Section 2(c), the terms “Phase 3 Landlord’s
Work,” “Tenant Delays” and “Substantially Completed” shall have the meanings set forth for such terms in the Work Letter. If Tenant does not elect to void this Lease within 5 business days of the lapse of
such 90 day period, such right to void this Lease shall be waived and this Lease shall remain in full force and effect. 
 The
“Subsequent Premises Commencement Date” shall be the earlier of: (i) the date (v) Landlord Delivers the Subsequent Premises to Tenant in vacant, broom clean condition with the portions of the Phase 3 Landlord’s Work
being performed in the Subsequent Premises, if any, Substantially Completed, and (x) all of the Phase 3 Landlord’s Work being performed in other portions of the Long-Term Premises is Substantially Completed; and (ii) the date Landlord
could have (y) Delivered the Subsequent Premises to Tenant in vacant, broom clean condition with the portions of the Phase 3 Landlord’s Premises being performed in the Subsequent Premises, if any, Substantially Completed, and
(z) Substantially Completed all of the Phase 3 Landlord’s Work being performed in other portions of the Long-Term Premises but for Tenant Delays. Tenant shall commence paying Long-Term Premises Base Rent with respect to the entire Initial
Premises and the Subsequent Premises on the Subsequent Premises Commencement Date. 
 Subject to the provisions of
Section 6 of the Work Letter, Landlord shall permit Tenant access to the Subsequent Premises for a period of 10 days prior to the Subsequent Premises Commencement Date for FF&E Installation in the Subsequent Premises,
provided that such FF&E Installation is coordinated with 

  
 5 

 
Landlord, and Tenant complies with the Lease and all other reasonable restrictions and conditions Landlord may impose. All such access shall be during normal business hours. Any access to the
Subsequent Premises by Tenant exclusively for FF&E Installation before the Subsequent Premises Commencement Date shall be subject to all of the terms and conditions of this Lease, excluding the obligation to pay Base Rent or Operating Expenses.

 If, during the period that Landlord is performing the Phase 3 Landlord’s Work pursuant to the Work Letter, if any, there are
portions of the Subsequent Premises in which the Phase 3 Landlord’s Work is not being performed, Landlord shall, subject to fourth sentence of this paragraph, allow Tenant to occupy and conduct business in all or any such portions of the
Subsequent Premises (the “Subsequent Premises Early Occupancy Space”). If Tenant occupies any Subsequent Premises Early Occupancy Space, the rentable square footage of such Subsequent Premises Early Occupancy Space shall be
added to and be included under this Lease as part of the Month-to-Month Premises commencing on the date that Tenant commences occupying such Subsequent Premises Early
Occupancy Space; provided, however, that, notwithstanding anything to the contrary contained in this Lease or the Work Letter, until the date upon which the portion of the Phase 3 Landlord’s Work being performed in the Subsequent Premises, if
any, has been Substantially Completed, Tenant shall not be required to pay Base Rent or Operating Expense for any rentable square footage of the Month-to-Month Premises
in excess of 12,918 rentable square feet. Commencing on the date that the Phase 3 Landlord’s Work being performed in the Subsequent Premises, if any, has been Substantially Completed, through the Subsequent Premises Commencement Date,
notwithstanding anything to the contrary contained in this Lease or the Work Letter, Tenant shall be required to pay Month-to-Month Premises Base Rent on the actual
rentable square footage of the Premises occupied by Tenant at any time. Notwithstanding anything to the contrary contained herein, Landlord shall have the right to exclude Tenant and any Tenant Parties from all or any portion of the Subsequent
Premises Early Occupancy Space until Substantial Completion of the Phase 3 Landlord’s Work being performed in the Subsequent Premises if any such occupancy interferes, as reasonably determined by Landlord, with the performance of the Phase 3
Landlord’s Work in the Subsequent Premises. If the Subsequent Premises Early Occupancy Space is available and Tenant desires to operate in such Subsequent Premises Early Occupancy Space, Landlord and Tenant shall enter into an amendment of this
Lease in a form acceptable to Landlord and Tenant each in their reasonable discretion, providing for the expansion of the Month-to-Month Premises to include such
Subsequent Premises Early Occupancy Space pursuant to the terms of this paragraph. 
 For the period of 60 consecutive days after the
Subsequent Premises Commencement Date, Landlord shall, at its sole cost and expense (which shall not constitute an Operating Expense), be responsible for any repairs that are required to be made to the Building Systems (as defined in
Section 13) serving the Subsequent Premises, unless Tenant or any Tenant Party was responsible for the cause of such repair, in which case Tenant shall pay the cost. 

Except as set forth in the Work Letter: (i) Tenant shall accept the Subsequent Premises in their condition as of the Subsequent Premises
Commencement Date, subject to all applicable Legal Requirements (as defined in Section 7 hereof); (ii) Landlord shall have no obligation for any defects in the Subsequent Premises; and (iii) Tenant’s taking
possession of the Subsequent Premises shall be conclusive evidence that Tenant accepts the Subsequent Premises and that the Subsequent Premises were in good condition at the time possession was taken. 

(d)    General. Upon request of Landlord, Tenant shall execute and deliver one or more written acknowledgment(s) of
the First Initial Premises Commencement Date, the Month-to-Month Premises Rent Commencement Date and the Second Initial Premises Commencement Date, and/or a written
acknowledgement of the Subsequent Premises Commencement Date, and the expiration date of the Term when such are established substantially in the form of the “Acknowledgement of Commencement Date” attached to this Lease as Exhibit D;
provided, however, Tenant’s failure to execute and deliver such acknowledgment shall not affect Landlord’s rights hereunder. The “Term” of this Lease shall be the Month-to-Month Base Term with respect to the Month-to-Month Premises (provided that the Term of this Lease with respect to the
Second Initial Premises shall not commence until the Second Initial Premises Commencement Date), and the Long-Term Base Term with respect to the Long-Term Premises, both as defined above on the first page of this Lease, and the Extension Term which
Tenant may elect with respect to the Long-Term Premises only pursuant to Section 39 hereof. 

  
 6 

 During the Term, Tenant shall have the right to use the furniture and equipment belonging to
Landlord identified on Exhibit J attached hereto (collectively, “Landlord’s Furniture”), which, as of the date of this Lease, is located in the Initial Premises. Tenant shall have no right to remove any of
Landlord’s Furniture from the Premises without Landlord’s prior written consent and Landlord’s Furniture shall be returned to Landlord at the expiration or earlier termination of the Term in substantially the same condition as
received by Tenant, except for ordinary wear and tear and casualty. 
 Except as set forth in this Lease: (i) Tenant shall accept
Landlord’s Furniture in its condition as of the First Initial Premises Commencement Date or Second Initial Premises Commencement Date, as applicable, subject to all applicable Legal Requirements; (ii) Landlord shall have no obligation for
any defects in Landlord’s Furniture; and (iii) Tenant’s taking possession of Landlord’s Furniture shall be conclusive evidence that Tenant accepts Landlord’s Furniture and that Landlord’s Furniture was in good condition
at the time possession was taken. 
 Tenant agrees and acknowledges that neither Landlord nor any agent of Landlord has made any
representation or warranty with respect to the condition of all or any portion of the Premises, Landlord’s Furniture or the Project, and/or the suitability of the Premises, Landlord’s Furniture or the Project for the conduct of
Tenant’s business, and Tenant waives any implied warranty that the Premises, Landlord’s Furniture or the Project are suitable for the Permitted Use. This Lease constitutes the complete agreement of Landlord and Tenant with respect to the
subject matter hereof and supersedes any and all prior representations, inducements, promises, agreements, understandings and negotiations which are not contained herein. Landlord in executing this Lease does so in reliance upon Tenant’s
representations, warranties, acknowledgments and agreements contained herein. 
 3.    Rent. 

(a)    Base Rent. Base Rent with respect to the Prior Premises and the First Initial Premises for the month in which
the Month-to-Month Premises Rent Commencement Date occurs and the Security Deposit shall be due and payable on delivery of an executed copy of this Lease to Landlord.
Commencing on the Month-to-Month Premises Rent Commencement Date with respect to the Prior Premises and the First Initial Premises, commencing on the Second Initial
Premises Commencement Date with respect to the Second Initial Premises and commencing on the Subsequent Premises Commencement Date with respect to the Long-Term Premises, Tenant shall pay to Landlord in advance, without demand, abatement, deduction
or set-off, monthly installments of Base Rent on or before the first day of each calendar month during the Term hereof, in lawful money of the United States of America, at the office of Landlord for payment of
Rent set forth above, or to such other person or at such other place as Landlord may from time to time designate in writing. Payments of Base Rent for any fractional calendar month shall be prorated. The obligation of Tenant to pay Base Rent and
other sums to Landlord and the obligations of Landlord under this Lease are independent obligations. Tenant shall have no right at any time to abate, reduce, or set-off any Rent (as defined in
Section 5) due hereunder except for any abatement as may be expressly provided in this Lease. 

(b)    Additional Rent. In addition to Base Rent, Tenant agrees to pay to Landlord as additional rent
(“Additional Rent”): (i) Tenant’s Share of “Operating Expenses” (as defined in Section 5), and (ii) any and all other amounts Tenant assumes or agrees to pay under the provisions of this
Lease, including, without limitation, any and all other sums that may become due by reason of any default of Tenant or failure to comply with the agreements, terms, covenants and conditions of this Lease to be performed by Tenant, after any
applicable notice and cure period. 
 4.    Base Rent Adjustments. 

(a)    Annual Adjustments. Base Rent shall be increased on each annual anniversary of the Subsequent Premises
Commencement Date (each an “Adjustment Date”) by multiplying the Base Rent 

  
 7 

 
payable immediately before such Adjustment Date by the Rent Adjustment Percentage and adding the resulting amount to the Base Rent payable immediately before such Adjustment Date. Base Rent, as
so adjusted, shall thereafter be due as provided herein. Base Rent adjustments for any fractional calendar month shall be prorated. 

(b)    Additional TI Allowance. Landlord shall, subject to the terms of the Work Letter, make the Additional Tenant
Improvement Allowance (as defined in the Work Letter) available to Tenant for the payment of TI Costs (as defined in the Work Letter). To the extent that Tenant elects to use any portion of the Additional Tenant Improvement Allowance, if at all,
commencing on the Subsequent Premises Commencement Date and continuing thereafter on the first day of each month during the Base Term, Tenant shall pay the amount necessary to fully amortize the portion of the Additional Tenant Improvement Allowance
actually funded by Landlord, if any, as adjusted as additional disbursements of the Additional Tenant Improvement Allowance occur, in equal monthly payments with interest at a rate of 9% per annum over the Long-Term Base Term, which interest shall
begin to accrue on the date that Landlord first disburses such Additional Tenant Improvement Allowance or any portion(s) thereof. 

5.    Operating Expense Payments. Landlord shall deliver to Tenant a written estimate of Operating Expenses for
each calendar year during the Term (the “Annual Estimate”), which may be revised by Landlord from time to time during such calendar year. Commencing on the
Month-to-Month Commencement Date with respect to the Prior Premises and the First Initial Premises, commencing on the Second Initial Premises Commencement Date with
respect to Second Initial Premises and commencing on the Subsequent Premises Commencement Date with respect to the Long-Term Premises, and continuing thereafter on the first day of each month during the Term, Tenant shall pay Landlord an amount
equal to 1/12th of Tenant’s Share of the Annual Estimate. Payments for any fractional calendar month shall be prorated. 
 For the
avoidance of doubt, for the period commencing on the First Initial Premises Commencement Date through the day immediately preceding the Second Initial Premises Commencement Date, Tenant Share of Operating Expenses shall be equal to 3.07%. 

The term “Operating Expenses” means all costs and expenses of any kind or description whatsoever incurred or accrued each
calendar year by Landlord with respect to the Project (including, without duplication, Taxes (as defined in Section 9), capital repairs and improvements, all of which capital repairs and improvements shall be amortized over
the lesser of 10 years and the useful life of such capital items, and the costs of Landlord’s third party property manager (not to exceed 3% of Base Rent) or, if there is no third party property manager, administration rent in the amount of
3.0% of Base Rent), excluding only: 
 (a)    the original construction costs of the Project and renovation prior to the
date of the Lease and costs of correcting defects in such original construction or renovation; 
 (b)    capital
expenditures for expansion of the Project; 
 (c)    costs incurred to remove, study, test or remediate, or otherwise

(B) originated from any separately demised tenant space within the Project other than the Premises, or (C) were not brought upon, kept, used stored, handled, treated, generated in, or released or disposed of from the Project by Tenant or
any Tenant Party, except to the extent, in any such case, the presence of such Hazardous Materials (1) was the result of a breach of any of Tenant’s obligations under this Lease by Tenant or any Tenant Party, or (2) was caused by,
contributed to, or exacerbated by Tenant or any Tenant Party; 
 (d)    interest, principal payments of Mortgage (as
defined in Section 27) debts of Landlord, financing costs and amortization of funds borrowed by Landlord, whether secured or unsecured and all payments or base rent (but not taxes or operating expenses) under any ground
lease or other underlying lease of all or any portion of the Project; 

  
 8 

 (e)    depreciation of the Project and capital reserves (except for
capital improvements amortized as set forth above, the cost of which are includable in Operating Expenses); 

(f)    advertising, legal and space planning expenses and leasing commissions and other costs and expenses incurred in
procuring and leasing space to tenants for the Project, including any leasing office maintained in the Project, free rent and construction allowances for tenants; 

(g)    legal and other expenses incurred in the negotiation or enforcement of leases; 

(h)    completing, fixturing, improving, renovating, painting, redecorating or other work, which Landlord pays for or

reimbursed by other tenants of the Project or Taxes to be paid directly by Tenant or other tenants of the Project, whether or not actually paid; 

(j)    salaries, wages, benefits and other compensation paid to officers and employees of Landlord who are not assigned in

(l)    costs (including attorneys’ fees and costs of settlement, judgments and payments in lieu thereof) incurred in
connection with disputes with tenants, other occupants, or prospective tenants, and costs and expenses, including legal fees, incurred in connection with negotiations or disputes with employees, consultants, management agents, leasing agents,
purchasers or mortgagees of the Building; 
 (m)    costs incurred by Landlord due to the violation by Landlord, its
employees, agents or contractors or any tenant of the terms and conditions of any lease of space in the Project or any Legal Requirement (as defined in Section 7); 

(n)    penalties, fines or interest incurred as a result of Landlord’s inability or failure to make payment of Taxes

(o)    overhead and profit increment paid to Landlord or to subsidiaries or affiliates of Landlord for goods and/or

concession within the Project; 
 (u)    the costs incurred in connection with the performance of alterations or
modifications to the Common Areas of the Project that are required solely due to the non-compliance of the Common Areas of the Project with Legal Requirements applicable to the Common Areas of the Project as
of the First Initial Premises Commencement Date, except to the extent such alterations or modifications are triggered by reason of Tenant’s particular use of the Premises or Tenant’s Alterations, in which case Tenant shall be solely
responsible subject to Section 7; and 
 (v)    any expenses otherwise includable within
Operating Expenses to the extent actually reimbursed by persons other than tenants of the Project under leases for space in the Project. 

Notwithstanding anything to the contrary contained in this Lease, (i) commencing on the Month-to-Month Commencement Date through the day immediately preceding the Subsequent Premises Commencement Date, Tenant’s Share of each earthquake deductible or occurrence of uninsured earthquake damage
affecting the Premises shall not exceed $1.50 per rentable square foot of the Month-to-Month Premises, and (ii) commencing on the Subsequent Premises Commencement
Date, Tenant’s Share of each earthquake deductible or occurrence of uninsured earthquake damage affecting the Premises shall not exceed $7.50 per rentable square foot of the Long Term Premises (“Initial Cap”). On each annual
anniversary of the Subsequent Premises Commencement Date, the Initial Cap shall be reduced by $1.50 per rentable square foot of the Long-Term Premises. Following earthquake damage to the Project, Tenant shall pay Tenant’s Share of any such
deductible or uninsured damage in equal monthly installments (not to exceed the Initial Cap) amortized over the remaining balance of the Base Term. 

Within 90 days after the end of each calendar year (or such longer period as may be reasonably required), Landlord shall furnish to Tenant a
statement (an “Annual Statement”) showing in reasonable detail: (a) the total and Tenant’s Share of actual Operating Expenses for the previous calendar year, and (b) the total of Tenant’s payments in respect of
Operating Expenses for such year. If Tenant’s Share of actual Operating Expenses for such year exceeds Tenant’s payments of Operating Expenses for such year, the excess shall be due and payable by Tenant as Rent within 30 days after
delivery of such Annual Statement to Tenant. If Tenant’s payments of Operating Expenses for such year exceed Tenant’s Share of actual Operating Expenses for such year Landlord shall pay the excess to Tenant within 30 days after delivery of
such Annual Statement, except that after the expiration, or earlier termination of the Term or if Tenant is delinquent in its obligation to pay Rent, Landlord shall pay the excess to Tenant after deducting all other amounts due Landlord. 

The Annual Statement shall be final and binding upon Tenant unless Tenant, within 45 days after Tenant’s receipt thereof, shall contest
any item therein by giving written notice to Landlord, specifying each item contested and the reason therefor. If, during such 45 day period, Tenant reasonably and in good faith questions or contests the accuracy of Landlord’s statement of
Tenant’s Share of Operating Expenses, Landlord will provide Tenant with access to Landlord’s books and records relating to the operation of the Project and such information as Landlord reasonably determines to be responsive to
Tenant’s questions (the “Expense Information”). If after Tenant’s review of such Expense Information, Landlord and Tenant cannot agree upon the amount of Tenant’s Share of Operating Expenses, then Tenant shall have
the right to have an independent public accounting firm selected by Tenant from among the 4 largest in the United States, working pursuant to a fee arrangement other than a contingent fee (at Tenant’s sole cost and expense) and approved by
Landlord (which approval shall not be unreasonably withheld or delayed), audit and/or review the Expense Information for the year in question (the “Independent Review”). The results of any such Independent Review shall be binding on
Landlord and Tenant. If the Independent Review shows that the payments actually made by Tenant with respect to Operating Expenses for the calendar year in question exceeded Tenant’s Share of Operating Expenses for such calendar year, Landlord
shall at Landlord’s option either (i) credit the excess amount to the next succeeding installments of estimated Operating Expenses or (ii) pay the excess to Tenant within 30 days after delivery of such statement, except that after the
expiration or earlier termination of this Lease or if Tenant is delinquent in its obligation to pay Rent, Landlord shall pay the excess to Tenant after deducting all other amounts due Landlord. If the

  
 10 

 
Independent Review shows that Tenant’s payments with respect to Operating Expenses for such calendar year were less than Tenant’s Share of Operating Expenses for the calendar year,
Tenant shall pay the deficiency to Landlord within 30 days after delivery of such statement. If the Independent Review shows that Tenant has overpaid with respect to Operating Expenses by more than 5% then Landlord shall reimburse Tenant for all
costs incurred by Tenant for the Independent Review. Operating Expenses for the calendar years in which Tenant’s obligation to share therein begins and ends shall be prorated. Notwithstanding anything set forth herein to the contrary, if the
Project is not at least 95% occupied on average during any year of the Term, Tenant’s Share of Operating Expenses for such year shall be computed as though the Project had been 95% occupied on average during such year. 

“Tenant’s Share” shall be the percentage set forth on the first page of this Lease as Tenant’s Share as reasonably
adjusted by Landlord for changes in the physical size of the Premises or the Project occurring thereafter. The rentable area of the Premises shall not be subject to re-measurement by either party during the
Term. If Landlord has a reasonable basis for doing so, Landlord may equitably increase Tenant’s Share for any item of expense or cost reimbursable by Tenant that relates to a repair, replacement, or service that benefits only the
Premises or only a portion of the Project that includes the Premises or that varies with occupancy or use. Base Rent, Tenant’s Share of Operating Expenses and all other amounts payable by Tenant to Landlord hereunder are collectively referred
to herein as “Rent.” 
 6.    Security Deposit. Tenant shall deposit with Landlord, upon
delivery of an executed copy of this Lease to Landlord, a security deposit (the “Security Deposit”) for the performance of all of Tenant’s obligations hereunder in the amount set forth on page 1 of this Lease. A portion of the
Security Deposit, in the amount of $25,000, shall be in the form of cash, and the balance of the Security Deposit, in the amount of $63,000.50, shall be in the form of an unconditional and irrevocable letter of credit (the “Letter of
Credit”): (i) in form and substance satisfactory to Landlord, (ii) naming Landlord as beneficiary, (iii) expressly allowing Landlord to draw upon it at any time from time to time by delivering to the issuer notice that Landlord is
entitled to draw thereunder, (iv) issued by an FDIC-insured financial institution satisfactory to Landlord, and (v) redeemable by presentation of a sight draft in the state of Landlord’s choice. If Tenant does not provide Landlord
with a substitute Letter of Credit complying with all of the requirements hereof at least 10 days before the stated expiration date of any then current Letter of Credit, Landlord shall have the right to draw the full amount of the current Letter of
Credit and hold the funds drawn in cash without obligation for interest thereon as the Security Deposit. The Security Deposit shall be held by Landlord as security for the performance of Tenant’s obligations under this Lease. The Security
Deposit is not an advance rental deposit or a measure of Landlord’s damages in case of Tenant’s default. Upon each occurrence of a Default (as defined in Section 20), Landlord may use all or any part of the
Security Deposit to pay delinquent payments due under this Lease, future rent damages under California Civil Code Section 1951.2, and the cost of any damage, injury, expense or liability caused by such Default, without prejudice to any other
remedy provided herein or provided by law. Landlord’s right to use the Security Deposit under this Section 6 includes the right to use the Security Deposit to pay future rent damages following the termination of this
Lease pursuant to Section 21(c) below. Upon any use of all or any portion of the Security Deposit, Tenant shall pay Landlord on demand the amount that will restore the Security Deposit to the amount set forth on Page 1 of
this Lease. Tenant hereby waives the provisions of any law, now or hereafter in force, including, without limitation, California Civil Code Section 1950.7, which provide that Landlord may claim from a security deposit only those sums reasonably
necessary to remedy defaults in the payment of Rent, to repair damage caused by Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other loss or
damage, foreseeable or unforeseeable, caused by the act or omission of Tenant or any officer, employee, agent or invitee of Tenant. Upon bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be
applied first to the payment of Rent and other charges due Landlord for periods prior to the filing of such proceedings. Upon any such use of all or any portion of the Security Deposit, Tenant shall, within 5 days after demand from Landlord, restore
the Security Deposit to its original amount. If Tenant shall fully perform every provision of this Lease to be performed by Tenant, the Security Deposit, or any balance thereof (i.e., after deducting therefrom all amounts to which Landlord is
entitled under the provisions of this Lease), shall be returned to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder) within 60 days after the expiration or earlier termination of this Lease. 

  
 11 

 If Landlord transfers its interest in the Project or this Lease, Landlord shall either
(a) transfer any Security Deposit then held by Landlord to a person or entity assuming Landlord’s obligations under this Section 6, or (b) return to Tenant any Security Deposit then held by Landlord and
remaining after the deductions permitted herein. Upon such transfer to such transferee or the return of the Security Deposit to Tenant, Landlord shall have no further obligation with respect to the Security Deposit, and Tenant’s right to the
return of the Security Deposit shall apply solely against Landlord’s transferee. The Security Deposit is not an advance rental deposit or a measure of Landlord’s damages in case of Tenant’s default. Landlord’s obligation
respecting the Security Deposit is that of a debtor, not a trustee, and no interest shall accrue thereon. 
 Notwithstanding anything to the
contrary contained herein, the parties hereto agree that Tenant may deposit the sum of $88,000.50 in cash with Landlord as the Security Deposit under this Lease concurrent with Tenant’s delivery to Landlord of an original of this Lease executed
by Tenant; provided, however, that Tenant shall replace a portion of the cash Security Deposit in the amount of $63,000.50 with a Letter of Credit within 30 days thereafter. Promptly after the delivery to Landlord of the approved and effective
Letter of Credit in the amount of $63,000.50, Landlord shall return a portion of the cash Security Deposit, in the amount of $63,000.50, to Tenant. 

7.    Use. The Premises shall be used solely for the Permitted Use set forth in the basic lease provisions on page
1 of this Lease, and in compliance with all laws, orders, judgments, ordinances, regulations, codes, directives, permits, licenses, covenants and restrictions now or hereafter applicable to the Premises, and to the use and occupancy thereof,
including, without limitation, the Americans With Disabilities Act, 42 U.S.C. § 12101, et seq. (together with the regulations promulgated pursuant thereto, “ADA”) (collectively, “Legal Requirements” and each, a
“Legal Requirement”). Tenant shall, upon 5 days’ written notice from Landlord, discontinue any use of the Premises which is declared by any Governmental Authority (as defined in Section 9) having
jurisdiction to be a violation of a Legal Requirement. Tenant will not use or permit the Premises to be used for any purpose or in any manner that would void Tenant’s or Landlord’s insurance, increase the insurance risk, or cause the
disallowance of any sprinkler or other credits. The use that Tenant has disclosed to Landlord that Tenant will be making of the Premises as of the First Initial Premises Commencement Date will not result in the voidance of or an increased insurance
risk with respect to the insurance currently being maintained by Landlord. Tenant shall not permit any part of the Premises to be used as a “place of public accommodation”, as defined in the ADA or any similar legal requirement. Tenant
shall not permit any part of the Premises to be used as a “place of public accommodation”, as defined in the ADA or any similar legal requirement. Tenant shall reimburse Landlord promptly upon demand for any additional premium charged for
any such insurance policy by reason of Tenant’s failure to comply with the provisions of this Section or otherwise caused by Tenant’s use and/or occupancy of the Premises. Tenant will use the Premises in a careful, safe and proper manner
and will not commit or permit waste, overload the floor or structure of the Premises, subject the Premises to use that would damage the Premises or obstruct or interfere with the rights of Landlord or other tenants or occupants of the Project,
including conducting or giving notice of any auction, liquidation, or going out of business sale on the Premises, or using or allowing the Premises to be used for any unlawful purpose. Tenant shall cause any equipment or machinery to be installed in
the Premises so as to reasonably prevent sounds or vibrations from the Premises from extending into Common Areas, or other space in the Project. Tenant shall not place any machinery or equipment which will overload the floor in or upon the Premises
or transport or move such items through the Common Areas of the Project or in the Project elevators without the prior written consent of Landlord. Except as may be provided under the Work Letter, Tenant shall not, without the prior written consent
of Landlord, use the Premises in any manner which will require ventilation, air exchange, heating, gas, steam, electricity or water beyond the existing capacity of the Project as proportionately allocated to the Premises based upon Tenant’s
Share as usually furnished for the Permitted Use. 
 Landlord shall be responsible for the compliance of the Common Areas of the Project
with Legal Requirements, including the ADA, as of the date of this Lease. Following the First Initial Premises Commencement Date, Landlord shall, as an Operating Expense (to the extent such Legal Requirement is generally applicable to similar
buildings in the area in which the Project is located) and at Tenant’s expense (to the extent such Legal Requirement is triggered by reason of Tenant’s, as compared to other tenants of 

  
 12 

 
the Project, specific use of the Premises or Tenant’s alterations) make any alterations or modifications to the Common Areas or the exterior of the Building that are required by Legal
Requirements. Except as provided in the two immediately preceding sentences, Tenant, at its sole expense, shall make any alterations or modifications to the interior of the Premises that are required by Legal Requirements (including, without
limitation, compliance of the Premises with the ADA related to Tenant’s particular use or occupancy of the Premises or Tenant’s Alterations. Notwithstanding any other provision herein to the contrary, Tenant shall be responsible for any
and all demands, claims, liabilities, losses, costs, expenses, actions, causes of action, damages or judgments, and all reasonable expenses incurred in investigating or resisting the same (including, without limitation, reasonable attorneys’
fees, charges and disbursements and costs of suit) (collectively, “Claims”) arising out of or in connection with Tenant’s failure to comply with Legal Requirements related to Tenant’s particular use or occupancy of the
Premises or Tenant’s Alterations, and Tenant shall indemnify, defend, hold and save Landlord harmless from and against any and all Claims arising out of or in connection with any failure of the Premises to comply with any Legal Requirement
related to Tenant’s particular use or occupancy of the Premises or Tenant’s Alterations. For purposes of Section 1938 of the California Civil Code, as of the date of this Lease, the Project has not been inspected by a certified access
specialist. 
 8.    Holding Over. If, with Landlord’s express written consent, Tenant retains possession of
the Premises after the termination of the Term, (i) unless otherwise agreed in such written consent, such possession shall be subject to immediate termination by Landlord at any time, (ii) all of the other terms and provisions of this
Lease (including, without limitation, the adjustment of Base Rent pursuant to Section 4 hereof) shall remain in full force and effect (excluding any expansion or renewal option or other similar right or option) during such
holdover period, (iii) Tenant shall continue to pay Base Rent in the amount payable upon the date of the expiration or earlier termination of this Lease or such other amount as Landlord may indicate, in Landlord’s sole and absolute
discretion, in such written consent, and (iv) all other payments shall continue under the terms of this Lease. If Tenant remains in possession of the Premises after the expiration or earlier termination of the Term without the express written
consent of Landlord, (A) Tenant shall become a tenant at sufferance upon the terms of this Lease except that (i) the monthly rental for the first 90 days of the tenancy at sufferance shall be equal to 150% of the Rent in effect during the
last 30 days prior to the expiration or earlier termination of the Lease, and (ii) the monthly rental for any period after the first 90 days of such tenancy at sufferance shall be equal to 200% of Rent in effect during the last 30 days prior to
the expiration or earlier termination of the Lease, and (B) Tenant shall be responsible for all damages suffered by Landlord resulting from or occasioned by Tenant’s holding over, including consequential damages. No holding over by Tenant,
whether with or without consent of Landlord, shall operate to extend this Lease except as otherwise expressly provided, and this Section 8 shall not be construed as consent for Tenant to retain possession of the Premises.
Acceptance by Landlord of Rent after the expiration of the Term or earlier termination of this Lease shall not result in a renewal or reinstatement of this Lease. 

9.    Taxes. Landlord shall pay, as part of Operating Expenses, all taxes, levies, fees, assessments and
governmental charges of any kind, existing as of the Commencement Date or thereafter enacted (collectively referred to as “Taxes”), imposed by any federal, state, regional, municipal, local or other governmental authority or agency,
including, without limitation, quasi-public agencies (collectively, “Governmental Authority”) during the Term, including, without limitation, all Taxes: (i) imposed on or measured by or based, in whole or in part, on rent
payable to (or gross receipts received by) Landlord under this Lease and/or from the rental by Landlord of the Project or any portion thereof, or (ii) based on the square footage, assessed value or other measure or evaluation of any kind of the
Premises or the Project, or (iii) assessed or imposed by or on the operation or maintenance of any portion of the Premises or the Project, including parking, or (iv) assessed or imposed by, or at the direction of, or resulting from Legal
Requirements, or interpretations thereof, promulgated by any Governmental Authority, or (v) imposed as a license or other fee, charge, tax, or assessment on Landlord’s business or occupation of leasing space in the Project. Landlord may
contest by appropriate legal proceedings the amount, validity, or application of any Taxes or liens securing Taxes. Notwithstanding anything to the contrary herein, Landlord shall only charge Tenant for such assessments as if those assessments were
paid by Landlord over the longest possible term which Landlord is permitted to pay for the applicable assessments without additional charge other than interest, if any, provided under the terms of the underlying assessments. Notwithstanding

  
 13 

 
anything to the contrary contained in this Lease, Taxes shall not include any net income taxes, gross receipts tax, estate taxes or inheritance taxes imposed on Landlord except to the extent such
net income taxes are in substitution for any Taxes payable hereunder, or any late penalties, interest or fines. If any such Tax is levied or assessed directly against Tenant, then Tenant shall be responsible for and shall pay the same at such times
and in such manner as the taxing authority shall require. Tenant shall pay, prior to delinquency, any and all Taxes levied or assessed against any personal property or trade fixtures placed by Tenant in the Premises, whether levied or assessed
against Landlord or Tenant. If any Taxes on Tenant’s personal property or trade fixtures are levied against Landlord or Landlord’s property, or if the assessed valuation of the Project is increased by a value attributable to improvements
in or alterations to the Premises, whether owned by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, higher than the base valuation on which Landlord from time-to-time allocates Taxes to all tenants in the Project, Landlord shall have the right, but not the obligation, to pay such Taxes. Landlord’s determination of any excess assessed valuation shall be
binding and conclusive, absent manifest error. The amount of any such payment by Landlord shall constitute Additional Rent due from Tenant to Landlord immediately upon demand. 

10.    Parking. Subject to all matters of record, Force Majeure, a Taking (as defined in
Section 19 below) and the exercise by Landlord of its rights hereunder, Tenant shall be allocated and required to pay for 1.4 parking spaces per 1,000 rentable square feet of the Premises then being leased by Tenant, which
parking spaces shall be in those areas designated by Landlord for non-reserved parking in that certain parking garage located at 1670 Owens Street, San Francisco, California (which parking garage and the land
on which the parking garage is location shall be deemed for purposes of this Lease to be a part of the Project), subject in each case to Landlord’s rules and regulations and payment of $300 per month during the Base Term for each parking space
(“Parking Charges”), as such Parking Charges shall be adjusted pursuant to this Section 10. Commencing on the first anniversary of the Commencement Date and continuing thereafter on each annual anniversary
of the Commencement Date during the Term (each. a “Parking Charge Adjustment Date”), the Parking Charges shall be increased by multiplying the Parking Charges payable immediately before such Parking Charge Adjustment Date by 3%, and
adding the resulting amount to the Parking Charges payable immediately before such Parking Charge Adjustment Date. Landlord shall not be responsible for enforcing Tenant’s parking rights against any third parties, including without limitation
other tenants of the Project. 
 11.    Utilities, Services. Landlord shall provide, subject to the terms of this
Section 11, water, electricity, heat, light, power, sewer, and other utilities (including gas and fire sprinklers to the extent the Project is plumbed for such services), refuse and trash collection and janitorial services
(collectively, “Utilities”). Landlord shall pay, as Operating Expenses or subject to Tenant’s reimbursement obligation, for all Utilities used on the Premises, all maintenance charges for Utilities, and any storm sewer charges
or other similar charges for Utilities imposed by any Governmental Authority or Utility provider, and any taxes, penalties, surcharges or similar charges thereon. Landlord may cause, at Landlord’s expense, any Utilities to be separately metered. or charged directly to Tenant by the provider. Tenant shall pay directly to the Utility provider, prior to delinquency, any separately metered Utilities and services which may be furnished to Tenant
or the Premises during the Term. Tenant shall pay, as part of Operating Expenses, its share of all charges for jointly metered Utilities based upon consumption, as reasonably determined by Landlord. No interruption or failure of Utilities, from any
cause whatsoever other than Landlord’s willful misconduct, shall result in eviction or constructive eviction of Tenant, termination of this Lease or the abatement of Rent. Tenant agrees to limit use of water and sewer with respect to Common
Areas to normal restroom use. 
 Notwithstanding anything to the contrary set forth herein, if (i) a stoppage of an Essential Service
(as defined below) to the Premises shall occur and such stoppage is due solely to the gross negligence or willful misconduct of Landlord and not due in any part to any act or omission on the part of Tenant or any Tenant Party or any matter beyond
Landlord’s reasonable control (any such stoppage of an Essential Service being hereinafter referred to as a “Service Interruption”), and (ii) such Service Interruption continues for more than 5 consecutive business
days after Landlord shall have received written notice thereof from Tenant, and (iii) as a result of such Service Interruption, the conduct of Tenant’s normal operations in the Premises are materially and adversely affected, then, to the
extent that such Service Interruption is covered by rental interruption insurance carried by Landlord pursuant to this Lease, there 

  
 14 

 
shall be an abatement of one day’s Base Rent for each day during which such Service Interruption continues after such 5 business day period; provided, however, that if any part of the
Premises is reasonably useable for Tenant’s normal business operations or if Tenant conducts all or any part of its operations in any portion of the Premises notwithstanding such Service Interruption, then the amount of each daily abatement
of Base Rent shall only be proportionate to the nature and extent of the interruption of Tenant’s normal operations or ability to use the Premises. The rights granted to Tenant under this paragraph shall be Tenant’s sole and
exclusive remedy resulting from a failure of Landlord to provide services, and Landlord shall not otherwise be liable for any loss or damage suffered or sustained by Tenant resulting from any failure or cessation of services. For purposes hereof,
the term “Essential Services” shall mean the following services: access to the Premises, HVAC service, water, sewer and electricity, but in each case only to the extent that Landlord has an obligation to provide same to
Tenant under this Lease. The provisions of this paragraph shall only apply as long as the original Tenant is the tenant occupying the Premises under this Lease and shall not apply to any assignee or sublessee. 

Landlord’s sole obligation for either providing emergency generators or providing emergency
back-up power to Tenant shall be: (i) to provide emergency generators with not less than the capacity of the emergency generators located in the Building as of the Commencement Date, and (ii) to
contract with a third party to maintain the emergency generators as per the manufacturer’s standard maintenance guidelines. Landlord shall have no obligation to provide Tenant with operational emergency generators or back-up power or to supervise, oversee or confirm that the third party maintaining the emergency generators is maintaining the generators as per the manufacturer’s standard guidelines or otherwise. During any
period of replacement, repair or maintenance of the emergency generators when the emergency generators are not operational, including any delays thereto due to the inability to obtain parts or replacement equipment, Landlord shall have no obligation
to provide Tenant with an alternative back-up generator or generators or alternative sources of back-up power. Tenant expressly acknowledges and agrees that Landlord
does not guaranty that such emergency generators will be operational at all times or that emergency power will be available to the Premises when needed. 

12.    Alterations and Tenant’s Property. Any alterations, additions, or improvements made to the Premises by
or on behalf of Tenant, including additional locks or bolts of any kind or nature upon any doors or windows in the Premises, but excluding installation, removal or realignment of furniture systems (other than removal of furniture systems owned or
paid for by Landlord) not involving any modifications to the structure or connections (other than by ordinary plugs or jacks) to Building Systems (as defined in Section 13) (“Alterations”) shall be subject
to Landlord’s prior written consent, which may be given or withheld in Landlord’s sole discretion if any such Alteration affects the structure or Building Systems and shall not be otherwise unreasonably withheld. Tenant may construct
nonstructural Alterations in the Premises without Landlord’s prior approval if the aggregate cost of all such work in any 12 month period does not exceed $50,000 (a “Notice-Only Alteration”), provided Tenant notifies Landlord
in writing of such intended Notice-Only Alteration, and such notice shall be accompanied by plans, specifications, work contracts and such other information concerning the nature and cost of the Notice-Only Alteration as may be reasonably requested
by Landlord, which notice and accompanying materials shall be delivered to Landlord not less than 15 business days in advance of any proposed construction. If Landlord approves any Alterations, Landlord may impose such conditions on Tenant in
connection with the commencement, performance and completion of such Alterations as Landlord may deem appropriate in Landlord’s reasonable discretion. Any request for approval shall be in writing, delivered not less than 15 business days in
advance of any proposed construction, and accompanied by plans, specifications, bid proposals, work contracts and such other information concerning the nature and cost of the alterations as may be reasonably requested by Landlord, including the
identities and mailing addresses of all persons performing work or supplying materials. Landlord’s right to review plans and specifications and to monitor construction shall be solely for its own benefit, and Landlord shall have no duty to
ensure that such plans and specifications or construction comply with applicable Legal Requirements. Tenant shall cause, at its sole cost and expense, all Alterations to comply with insurance requirements and with Legal Requirements and shall
implement at its sole cost and expense any alteration or modification required by Legal Requirements as a result of any Alterations. Tenant shall pay to Landlord, as Additional Rent, on demand an amount equal to 3% of all charges incurred by Tenant
or its contractors or agents in connection with any Alteration costing in excess of $50,000 to cover Landlord’s overhead and expenses for plan review, coordination, 

  
 15 

 
scheduling and supervision. Before Tenant begins any Alteration, Landlord may post on and about the Premises notices of non-responsibility pursuant to
applicable law. Tenant shall reimburse Landlord for, and indemnify and hold Landlord harmless from, any expense incurred by Landlord by reason of faulty work done by Tenant or its contractors, delays caused by such work, or inadequate cleanup. 

Tenant shall furnish security or make other arrangements reasonably satisfactory to Landlord to assure payment for the completion of all
Alterations work free and clear of liens, and shall provide (and cause each contractor or subcontractor to provide) certificates of insurance for workers’ compensation and other coverage in amounts and from an insurance company satisfactory to
Landlord protecting Landlord against liability for personal injury or property damage during construction. Upon completion of any Alterations, Tenant shall deliver to Landlord: (i) sworn statements setting forth the names of all contractors and
subcontractors who did the work and final lien waivers from all such contractors and subcontractors; and (ii) “as built” plans for any such Alteration. 

Except for Removable Installations (as hereinafter defined), all Installations (as hereinafter defined) shall be and shall remain the property
of Landlord during the Term and following the expiration or earlier termination of the Term, shall not be removed by Tenant at any time during the Term, and shall remain upon and be surrendered with the Premises as a part thereof. Notwithstanding
the foregoing, Landlord may, at the time its approval of any such Installation is requested, or at the time it receives notice of a Notice-Only Alteration, notify Tenant that Landlord requires that Tenant remove such Installation upon the expiration
or earlier termination of the Term, in which event Tenant shall remove such Installation in accordance with the immediately succeeding sentence. Upon the expiration or earlier termination of the Term, Tenant shall remove (i) all wires, cables
or similar equipment which Tenant has installed in the Premises or in the risers or plenums of the Building, (ii) any Installations for which Landlord has given Tenant notice of removal in accordance with the immediately preceding sentence, and
(iii) all of Tenant’s Property (as hereinafter defined), and Tenant shall restore and repair any damage caused by or occasioned as a result of such removal, including, without limitation, capping off all such connections behind the walls
of the Premises and repairing any holes. During any restoration period beyond the expiration or earlier termination of the Term, Tenant shall pay Rent to Landlord as provided herein as if said space were otherwise occupied by Tenant. If Landlord is
requested by Tenant or any lender, lessor or other person or entity claiming an interest in any of Tenant’s Property to waive any lien Landlord may have against any of Tenant’s Property, and Landlord consents to such waiver, then Landlord
shall be entitled to be paid as administrative rent a fee of $1,000 per occurrence for its time and effort in preparing and negotiating such a waiver of lien. 

For purposes of this Lease, (x) “Removable Installations” means any items listed on Exhibit F attached hereto and any
items agreed by Landlord in writing to be included on Exhibit F in the future, (y) “Tenant’s Property” means Removable Installations and, other than Installations, any personal property or equipment of Tenant that
may be removed without material damage to the Premises, and (z) “Installations” means all property of any kind paid for with TI Fund (as such term is defined in the Work Letter and the Work Letter), all Alterations, all
fixtures, and all partitions, hardware, built-in machinery, built-in casework and cabinets and other similar additions, equipment, property and improvements built into
the Premises so as to become an integral part of the Premises, including, without limitation, fume hoods which penetrate the roof or plenum area, built-in cold rooms,
built-in warm rooms, walk-in cold rooms, walk-in warm rooms, deionized water systems, glass washing equipment, autoclaves,
chillers, built-in plumbing, electrical and mechanical equipment and systems, and any power generator and transfer switch. 

Tenant shall not be required to remove Landlord’s Work (as defined in the Work Letter) at the expiration or earlier termination of the
Term nor shall Tenant have the right to remove any Landlord’s Work at any time. 
 13.    Landlord’s
Repairs. Landlord, as an Operating Expense (except to the extent the cost thereof is excluded from Operating Expenses pursuant to Section 5 hereof), shall maintain all of the structural, exterior, parking and other Common Areas of the
Project, including HVAC, plumbing, fire sprinklers, elevators and all other building systems serving the Premises and other portions of the Project (“Building Systems”), in good repair, reasonable wear and tear and uninsured losses
and damages 

  
 16 

 
(unless such losses or damages would have been insured losses or expenses if the insurance Landlord is required to maintain hereunder had been obtained and so long as it would make reasonable
business sense to Landlord, bearing in mind the potential amount of the losses and damages and the amount of the applicable deductibles, to submit a claim for such losses and damages to its insurer) caused by Tenant, or by any of Tenant’s
agents, servants, employees, invitees and contractors (collectively, “Tenant Parties”) excluded. Subject to the provisions of the penultimate paragraph of Section 17, losses and damages caused by Tenant or
any Tenant Party shall be repaired by Landlord, at Tenant’s sole cost and expense, to the extent not covered by insurance Landlord is required to maintain hereunder (or to the extent such losses or damages would have been covered by insurance
Landlord is required to maintain hereunder if such insurance had been maintained and so long as it would make reasonable business sense to Landlord, bearing in mind the potential amount of the losses and damages and the amount of the applicable
deductibles, to submit a claim for such losses and damages to its insurer). Landlord shall have no responsibility or liability for failure to supply Building Systems services during any such period of interruption; provided, however,
that Landlord shall, except in case of emergency, make a commercially reasonable effort to give Tenant 48 hours advance notice of any planned stoppage of Building Systems services for routine maintenance, repairs, alterations or improvements.
Landlord shall use reasonable efforts to minimize interruption to Tenant’s business during such planned stoppages of Building Systems. Tenant shall promptly give Landlord written notice of any repair required by Landlord pursuant to this
Section, after which Landlord shall make a commercially reasonable effort to effect such repair. Landlord shall not be liable for any failure to make any repairs or to perform any maintenance unless such failure shall persist for an unreasonable
time after Tenant’s written notice of the need for such repairs or maintenance. Tenant waives its rights under any state or local law to terminate this Lease or to make such repairs at Landlord’s expense and agrees that the parties’
respective rights with respect to such matters shall be solely as set forth herein. Notwithstanding anything to the contrary contained herein, repairs required as the result of fire, earthquake, flood, vandalism, war, or similar cause of damage or
destruction shall be controlled by Section 18. 
 14.    Tenant’s Repairs. Subject
to Section 13 hereof, Tenant, at its expense, shall repair, replace and maintain in good condition all portions of the Premises, including, without limitation, entries, doors, ceilings, interior windows, interior walls, and
the interior side of demising walls. Should Tenant fail to make any such repair or replacement or fail to maintain the Premises, Landlord shall give Tenant notice of such failure. If Tenant fails to commence cure of such failure within 10 days of
Landlord’s notice, and thereafter diligently prosecute such cure to completion, Landlord may perform such work and shall be reimbursed by Tenant within 10 days after demand therefor; provided, however, that if such failure by Tenant creates or
could create an emergency, Landlord may immediately commence cure of such failure and shall thereafter be entitled to recover the costs of such cure from Tenant. Subject to Sections 17 and 18, Tenant shall bear the full uninsured cost
of any repair or replacement to any part of the Project that results from damage caused by Tenant or any Tenant Party and any repair that benefits only the Premises. 

15.    Mechanic’s Liens. Tenant shall discharge, by bond or otherwise, any mechanic’s lien filed against
the Premises or against the Project for work claimed to have been done for, or materials claimed to have been furnished to, Tenant within 10 days after the filing thereof, at Tenant’s sole cost and shall otherwise keep the Premises and the
Project free from any liens arising out of work performed, materials furnished or obligations incurred by Tenant. Should Tenant fail to discharge any lien described herein, Landlord shall have the right, but not the obligation, to pay such claim or
post a bond or otherwise provide security to eliminate the lien as a claim against title to the Project and the cost thereof shall be immediately due from Tenant as Additional Rent. If Tenant shall lease or finance the acquisition of office
equipment, furnishings, or other personal property of a removable nature utilized by Tenant in the operation of Tenant’s business, Tenant warrants that any Uniform Commercial Code Financing Statement filed as a matter of public record by any
lessor or creditor of Tenant will upon its face or by exhibit thereto indicate that such Financing Statement is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address of the Project be
furnished on the statement without qualifying language as to applicability of the lien only to removable personal property, located in an identified suite held by Tenant. 

  
 17 

 16.    Indemnification. Tenant hereby indemnifies and agrees to
defend, save and hold Landlord harmless from and against any and all Claims for injury or death to persons or damage to property occurring within or about the Premises, arising directly or indirectly out of use or occupancy of the Premises or a
breach or default by Tenant in the performance of any of its obligations hereunder, except to the extent caused by the willful misconduct or negligence of Landlord or the default by Landlord under this Lease. Landlord shall not be liable to Tenant
for, and Tenant assumes all risk of damage to, personal property (including, without limitation, loss of records kept within the Premises). Tenant further waives any and all Claims for injury to Tenant’s business or loss of income relating to
any such damage or destruction of personal property (including, without limitation, any loss of records). Landlord shall not be liable for any damages arising from any act, omission or neglect of any tenant in the Project or of any other third
party. 
 17.    Insurance. Landlord shall maintain all risk property and, if applicable, sprinkler damage
insurance covering the full replacement cost of the Project. Landlord shall further procure and maintain commercial general liability insurance with a single loss limit of not less than $2,000,000 for bodily injury and property damage with respect
to the Project. Landlord may, but is not obligated to, maintain such other insurance and additional coverages as it may deem necessary, including, but not limited to, flood, environmental hazard and earthquake, loss or failure of building equipment,
errors and omissions, rental loss during the period of repair or rebuilding, workers’ compensation insurance and fidelity bonds for employees employed to perform services and insurance for any improvements installed by Tenant or which are in
addition to the standard improvements customarily furnished by Landlord without regard to whether or not such are made a part of the Project. All such insurance shall be included as part of the Operating Expenses. The Project may be included in a
blanket policy (in which case the cost of such insurance allocable to the Project will be determined by Landlord based upon the insurer’s cost calculations). Tenant shall also reimburse Landlord for any increased premiums or additional
insurance which Landlord reasonably deems necessary as a result of Tenant’s use of the Premises. 
 Tenant, at its sole cost and
expense, shall maintain during the Term: all risk property insurance with business interruption and extra expense coverage, covering the full replacement cost of all property and improvements installed or placed in the Premises by Tenant at
Tenant’s expense; workers’ compensation insurance with no less than the minimum limits required by law; employer’s liability insurance with such limits as required by law; and commercial general liability insurance, with a minimum
limit of not less than $2,000,000 per occurrence for bodily injury and property damage with respect to the Premises. The commercial general liability insurance policy shall name Alexandria Real Estate Equities, Inc., and Landlord, its officers,
directors, employees, managers, agents, invitees and contractors (collectively, “Landlord Parties”), as additional insureds; insure on an occurrence and not a claims-made basis; be issued by insurance companies which have a rating
of not less than policyholder rating of A and financial category rating of at least Class X in “Best’s Insurance Guide”; shall not be cancelable for nonpayment of premium unless 10 days prior written notice shall have been given
to Landlord from the insurer; contain a hostile fire endorsement and a contractual liability endorsement; and provide primary coverage to Landlord (any policy issued to Landlord providing duplicate or similar coverage shall be deemed excess over
Tenant’s policies). Copies of such policies (if requested by Landlord), or certificates of insurance showing the limits of coverage required hereunder and showing Landlord as an additional insured, along with reasonable evidence of the payment
of premiums for the applicable period, shall be delivered to Landlord by Tenant upon commencement of the Term and upon each renewal of said insurance. Tenant’s policy may be a “blanket policy” with an aggregate per location
endorsement which specifically provides that the amount of insurance shall not be prejudiced by other losses covered by the policy. Tenant shall, at least 5 days prior to the expiration of such policies, furnish Landlord with renewal certificates.

 In each instance where insurance is to name Landlord as an additional insured, Tenant shall upon written request of Landlord also
designate and furnish certificates so evidencing Landlord as additional insured to: (i) any lender of Landlord holding a security interest in the Project or any portion thereof, (ii) the landlord under any lease wherein Landlord is tenant
of the real property on which the Project is located, if the interest of Landlord is or shall become that of a tenant under a ground or other underlying lease rather than that of a fee owner, and/or (iii) any management company retained by
Landlord to manage the Project. 

  
 18 

 The property insurance obtained by Landlord and Tenant shall include a waiver of subrogation
by the insurers and all rights based upon an assignment from its insured, against Landlord or Tenant, and their respective officers, directors, employees, managers, agents, invitees and contractors (“Related Parties”), in connection
with any loss or damage thereby insured against. Notwithstanding anything to the contrary contained in this Lease, neither party nor its respective Related Parties shall be liable to the other for loss or damage caused by any risk insured against
under property insurance required to be maintained hereunder regardless of the negligence of the party to the Lease receiving the benefit of the waiver, and each party waives any claims against the other party, and its respective Related Parties,
for such loss or damage. The failure of a party to insure its property shall not void this waiver. Landlord and its respective Related Parties shall not be liable for, and Tenant hereby waives all claims against such parties for, business
interruption and losses occasioned thereby sustained by Tenant or any person claiming through Tenant resulting from any accident or occurrence in or upon the Premises or the Project from any cause whatsoever. If the foregoing waivers shall
contravene any law with respect to exculpatory agreements, the liability of Landlord or Tenant shall be deemed not released but shall be secondary to the other’s insurer. 

Landlord may require insurance policy limits to be raised to conform with requirements of Landlord’s lender and/or to bring coverage
limits to levels then being generally required of new tenants within the Project; provided, however, that the increased amount of coverage is consistent with coverage amounts then being required by institutional owners of similar projects with
tenants occupying similar size premises in the geographical area in which the Project is located. 

18.    Restoration. If, at any time during the Term, the Project or the Premises are damaged or destroyed by a fire
or other casualty, Landlord shall notify Tenant within 60 days after discovery of such damage as to the amount of time Landlord reasonably estimates it will take to restore the Project or the Premises, as applicable (the “Restoration
Period”). If the Restoration Period is estimated to exceed 9 months (the “Maximum Restoration Period”), Landlord may, in such notice, elect to terminate this Lease as of the date that is 75 days after the date of
discovery of such damage or destruction; provided, however, that notwithstanding Landlord’s election to restore, Tenant may elect to terminate this Lease by written notice to Landlord delivered within 10 business days of receipt
of a notice from Landlord estimating a Restoration Period for the Premises longer than the Maximum Restoration Period. Unless either Landlord or Tenant so elects to terminate this Lease, Landlord shall, subject to receipt of sufficient insurance
proceeds (with any deductible to be treated as an Operating Expense subject to the provisions of Section 5), promptly restore the Premises (including the Tenant Improvements but excluding any other improvements installed by
Tenant or by Landlord and paid for by Tenant), subject to delays arising from the collection of insurance proceeds, from Force Majeure events or as needed to obtain any license, clearance or other authorization of any kind required to enter into and
restore the Premises issued by any Governmental Authority having jurisdiction over the use, storage, handling, treatment, generation, release, disposal, removal or remediation of Hazardous Materials (as defined in
Section 30) in, on or about the Premises (collectively referred to herein as “Hazardous Materials Clearances”); provided, however, that if repair or restoration of the Premises is not
substantially complete as of the end of the Maximum Restoration Period or, if longer, the Restoration Period, Landlord may, in its sole and absolute discretion, elect not to proceed with such repair and restoration or Tenant may by written notice to
Landlord delivered within 10 business days of the expiration of the Maximum Restoration Period or, if longer, the Restoration Period, elect to terminate this Lease, in which event Landlord shall be relieved of its obligation to make such repairs or
restoration and this Lease shall terminate as of the date that is 75 days after the later of: (i) discovery of such damage or destruction, or (ii) the date all required Hazardous Materials Clearances are obtained, but Landlord shall retain
any Rent paid and the right to any Rent payable by Tenant prior to such election by Landlord or Tenant. Notwithstanding the foregoing, if a portion of the Project not including the Premises is damaged, Landlord may not terminate this Lease on the
basis that the Restoration Period will exceed the Maximum Restoration Period if Landlord elects to merely repair the damage rather than redevelop or improve the Project as a whole, and Landlord actually commences construction of the repair of such
damage. In the event that this Lease terminates pursuant to the provisions of this Section 18 as a result of an earthquake, Tenant shall not be required to pay any deductibles as part of Operating Expenses in connection
with such earthquake. 

  
 19 

 Tenant, at its expense, shall promptly perform, subject to delays arising from the
collection of insurance proceeds, from Force Majeure (as defined in Section 34) events or to obtain Hazardous Material Clearances, all repairs or restoration to the Premises not required to be done by Landlord.
Notwithstanding the foregoing, either Landlord or Tenant may terminate this Lease upon written notice to the other if the Premises are damaged during the last year of the Term and Landlord reasonably estimates that it will take more than 2 months to
repair such damage; provided, however, that such notice is delivered within 10 business days after the date that Landlord provides Tenant with written notice of the estimated Restoration Period. Landlord shall also have the right to terminate this
Lease if insurance proceeds are not available for such restoration. Rent shall be abated from the date all required Hazardous Material Clearances are obtained until the Premises are repaired and restored, in the proportion which the area of the
Premises, if any, which is not usable by Tenant bears to the total area of the Premises, unless Landlord provides Tenant with other space in the Mission Bay area of San Francisco during the period of repair that is suitable for the temporary conduct
of Tenant’s business. In the event that no Hazardous Material Clearances are required to be obtained by Tenant with respect to the Premises, rent abatement shall commence on the date of discovery of the damage or destruction. Such abatement
shall be the sole remedy of Tenant, and except as provided in this Section 18, Tenant waives any right to terminate the Lease by reason of damage or casualty loss. 

The provisions of this Lease, including this Section 18, 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, or any other portion of the Project, and any statute or regulation which is now or may hereafter be in effect shall have no application to this Lease or any
damage or destruction to all or any part of the Premises or any other portion of the Project, the parties hereto expressly agreeing that this Section 18 sets forth their entire understanding and agreement with respect to
such matters. 
 19.    Condemnation. If the whole or any material part of the Premises or the Project is taken
for any public or quasi-public use under governmental law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof (a “Taking” or “Taken”), and the Taking would in
Landlord’s reasonable judgment, materially interfere with or impair Landlord’s ownership or operation of the Project or would in the reasonable judgment of Landlord and Tenant either prevent or materially interfere with Tenant’s use
of the Premises (as resolved, if the parties are unable to agree, by arbitration by a single arbitrator with the qualifications and experience appropriate to resolve the matter and appointed pursuant to and acting in accordance with the rules of the
American Arbitration Association), then upon written notice by Landlord or Tenant to the other, this Lease shall terminate and Rent shall be apportioned as of said date. If part of the Premises shall be Taken, and this Lease is not terminated as
provided above, Landlord shall promptly restore the Premises and the Project as nearly as is commercially reasonable under the circumstances to their condition prior to such partial Taking and the rentable square footage of the Building, the
rentable square footage of the Premises, Tenant’s Share of Operating Expenses and the Rent payable hereunder during the unexpired Term shall be reduced to such extent as may be fair and reasonable under the circumstances. Upon any such Taking,
Landlord shall be entitled to receive the entire price or award from any such Taking without any payment to Tenant, and Tenant hereby assigns to Landlord Tenant’s interest, if any, in such award. Tenant shall have the right, to the extent that
same shall not diminish Landlord’s award, to make a separate claim against the condemning authority (but not Landlord) for such compensation as may be separately awarded or recoverable by Tenant for moving expenses and damage to Tenant’s
trade fixtures, if a separate award for such items is made to Tenant. Tenant hereby waives any and all rights it might otherwise have pursuant to any provision of state law to terminate this Lease upon a partial Taking of the Premises or the
Project. 
 20.    Events of Default. Each of the following events shall be a default
(“Default”) by Tenant under this Lease: 
 (a)    Payment Defaults. Tenant shall fail to pay any
installment of Rent or any other payment hereunder when due; provided, however, that Landlord will give Tenant written notice and an opportunity to cure any failure to pay Rent within 5 days of any such notice not more than twice in any 12 month
period and Tenant agrees that such notice shall be in lieu of and not in addition to, or shall be deemed to be, any notice required by law. 

  
 20 

 (b)    Insurance. Any insurance required to be maintained by
Tenant pursuant to this Lease shall be canceled or terminated or shall expire or shall be reduced or materially changed, or Landlord shall receive a notice of nonrenewal of any such insurance and Tenant shall fail to obtain replacement insurance at
least 20 days before the expiration of the current coverage. 
 (c)    Abandonment. Tenant shall abandon the
Premises. 
 (d)    Improper Transfer. Tenant shall assign, sublease or otherwise transfer or attempt to transfer
all or any portion of Tenant’s interest in this Lease or the Premises except as expressly permitted herein, or Tenant’s interest in this Lease shall be attached, executed upon, or otherwise judicially seized and such action is not released
within 90 days of the action. 
 (e)    Liens. Tenant shall fail to discharge or otherwise obtain the release of
any lien placed upon the Premises in violation of this Lease within 10 days after Tenant’s receipt of notice that any such lien is filed against the Premises. 

(f)    Insolvency Events. Tenant or any guarantor or surety of Tenant’s obligations hereunder shall:
(A) make a general assignment for the benefit of creditors; (B) commence any case, proceeding or other action seeking to have an order for relief entered on its behalf as a debtor or to adjudicate it a bankrupt or insolvent, or seeking
reorganization, arrangement, adjustment, liquidation, dissolution or composition of it or its debts or seeking appointment of a receiver, trustee, custodian or other similar official for it or for all or of any substantial part of its property
(collectively a “Proceeding for Relief”); (C) become the subject of any Proceeding for Relief which is not dismissed within 90 days of its filing or entry; or (D) die or suffer a legal disability (if Tenant, guarantor, or
surety is an individual) or be dissolved or otherwise fail to maintain its legal existence (if Tenant, guarantor or surety is a corporation, partnership or other entity). 

(g)    Estoppel Certificate or Subordination Agreement. Tenant fails to execute any document required from Tenant
under Sections 23 or 27 within 5 days after a second notice requesting such document. 
 (h)    Other
Defaults. Tenant shall fail to comply with any provision of this Lease other than those specifically referred to in this Section 20, and, except as otherwise expressly provided herein, such failure shall continue for a
period of 30 days after written notice thereof from Landlord to Tenant. 
 Any notice given under Section 20(h) hereof shall:
(i) specify the alleged default, (ii) demand that Tenant cure such default, (iii) be in lieu of, and not in addition to, or shall be deemed to be, any notice required under any provision of applicable law, and (iv) not be deemed
a forfeiture or a termination of this Lease unless Landlord elects otherwise in such notice; provided that if the nature of Tenant’s default pursuant to Section 20(h) is such that it cannot be cured by the
payment of money and reasonably requires more than 30 days to cure, then Tenant shall not be deemed to be in default if Tenant commences such cure within said 30 day period and thereafter diligently prosecutes the same to completion;
provided, however, that such cure shall be completed no later than 45 days from the date of Landlord’s notice. 

21.    Landlord’s Remedies. 

(a)    Payment By Landlord; Interest. Upon a Default by Tenant hereunder, Landlord may, without waiving or releasing
any obligation of Tenant hereunder, make such payment or perform such act on behalf of Tenant. All sums so paid or incurred by Landlord, together with interest thereon, from the date such sums were paid or incurred, at the annual rate equal to 12%
per annum or the highest rate permitted by law (the “Default Rate”), whichever is less, shall be payable to Landlord on demand as Additional Rent. Nothing herein shall be construed to create or impose a duty on Landlord to mitigate
any damages resulting from Tenant’s Default hereunder. 
 (b)    Late Payment Rent. Late payment by Tenant
to Landlord of Rent and other sums due will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be 

  
 21 

 
extremely difficult and impracticable to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges which may be imposed on Landlord under any
Mortgage covering the Premises. Therefore, if any installment of Rent due from Tenant is not received by Landlord within 5 days after the date such payment is due, Tenant shall pay to Landlord an additional sum equal to 6% of the overdue Rent as a
late charge. Notwithstanding the foregoing, before assessing a late charge the first time in any calendar year, Landlord shall provide Tenant written notice of the delinquency and will waive the right if Tenant pays such delinquency within 5 days
thereafter. The parties agree that this late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. In addition to the late charge, Rent not paid when due shall bear interest at the
Default Rate from the 5th day after the date due until paid. 
 (c)    Remedies. Upon the occurrence of a Default
by Tenant, Landlord, at its option, without further notice or demand to Tenant, shall have in addition to all other rights and remedies provided in this Lease, at law or in equity, 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. 

(i)    Terminate this Lease, or at Landlord’s option, Tenant’s right to possession only, in which
event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the
Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; 

(ii)    Upon any termination of this Lease, whether pursuant to the foregoing
Section 21(c)(i), or otherwise, Landlord may recover from Tenant the following: 

(A)    The worth at the time of award of any unpaid rent which has been earned at the time of such
termination; plus 
 (B)    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 

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

(D)    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 

(E)    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 21 shall be deemed to
be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 21(c)(ii)(A) and (B), above, the “worth at the time of
award” shall be computed by allowing interest at the Default Rate. As used in Section 21(c)(ii)(C) 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 1%. 

  
 22 

 (iii)    Landlord may continue this Lease in effect
after Tenant’s Default and recover rent as it becomes due (Landlord and Tenant hereby agreeing that Tenant has the right to sublet or assign hereunder, subject only to reasonable limitations). Accordingly, if Landlord does not elect to
terminate this Lease following a Default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies hereunder, including the right to recover all Rent as it becomes due. 

(iv)    Whether or not Landlord elects to terminate this Lease following a Default by Tenant, Landlord
shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s
interest in such subleases, licenses, concessions or arrangements. Upon Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of
such election, have no further right to or interest in the rent or other consideration receivable thereunder. 

(v)    independent of the exercise of any other remedy of Landlord hereunder or under applicable law,
Landlord may conduct an environmental test of the Premises as generally described in Section 30(d) hereof, at Tenant’s expense. 

(d)    Effect of Exercise. Exercise by Landlord of any remedies hereunder or otherwise available shall not be
deemed to be an acceptance of surrender of the Premises and/or a termination of this Lease by Landlord, it being understood that such surrender and/or termination can be effected only by the express written agreement of Landlord and Tenant. Any law,
usage, or custom to the contrary notwithstanding, Landlord shall have the right at all times to enforce the provisions of this Lease in strict accordance with the terms hereof; and the failure of Landlord at any time to enforce its rights under this
Lease strictly in accordance with same shall not be construed as having created a custom in any way or manner contrary to the specific terms, provisions, and covenants of this Lease or as having modified the same and shall not be deemed a waiver of
Landlord’s right to enforce one or more of its rights in connection with any subsequent default. A receipt by Landlord of Rent or other payment with knowledge of the breach of any covenant hereof shall not be deemed a waiver of such breach, and
no waiver by Landlord of any provision of this Lease shall be deemed to have been made unless expressed in writing and signed by Landlord. Following a Default by Tenant under this Lease and to the greatest extent permitted by law, Tenant waives the
service of notice of Landlord’s intention to re-enter, re-take or otherwise obtain possession of the Premises as provided in any statute, or to institute legal
proceedings to that end, and also waives all right of redemption in case Tenant shall be dispossessed by a judgment or by warrant of any court or judge. Any reletting of the Premises or any portion thereof shall be on such terms and conditions as
Landlord in its sole discretion may determine. Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s failure to relet the Premises or collect rent due in respect of such reletting
or otherwise to mitigate any damages arising by reason of Tenant’s Default. 
 22.    Assignment and
Subletting. 
 (a)    General Prohibition. Without Landlord’s prior written consent subject to and on the
conditions described in this Section 22, Tenant shall not, directly or indirectly, voluntarily or by operation of law, assign this Lease or sublease the Premises or any part thereof or mortgage, pledge, or hypothecate its
leasehold interest or grant any concession or license within the Premises, and any attempt to do any of the foregoing shall be void and of no effect. If Tenant is a corporation, partnership or limited liability company, the shares or other ownership
interests thereof which are not actively traded upon a stock exchange or in the over-the-counter market, a transfer or series of transfers whereby 49% or more of the
issued and outstanding shares or other ownership interests of such corporation are, or voting control is, transferred (but excepting transfers upon deaths of individual owners) from a person or persons or entity or entities which were owners thereof
at time of execution of this Lease to persons or entities who were not owners of shares or other ownership interests of the corporation, partnership or limited liability company at time of execution of this Lease, shall be deemed an assignment of
this Lease requiring the consent of 

  
 23 

 
Landlord as provided in this Section 22. Notwithstanding the foregoing, Tenant shall have the right to obtain financing from investors (including venture capital funding
and corporate partners) or undergo a public offering which results in a change in control of Tenant without such change of control constituting an assignment under this Section 22 requiring Landlord consent, provided that
(i) Tenant notifies Landlord in writing of the financing at least 5 business days prior to the closing of the financing, and (ii) provided that in no event shall such financing result in a change in use of the Premises from the use
contemplated by Tenant at the commencement of the Term. 
 (b)    Permitted Transfers. If Tenant desires to
assign, sublease, hypothecate or otherwise transfer this Lease or sublet the Premises other than pursuant to a Permitted Assignment (as defined below), then at least 15 business days, but not more than 45 business days, before the date Tenant
desires the assignment or sublease to be effective (the “Assignment Date”), Tenant shall give Landlord a notice (the “Assignment Notice”) containing such information about the proposed assignee or sublessee,
including the proposed use of the Premises and any Hazardous Materials proposed to be used, stored handled, treated, generated in or released or disposed of from the Premises, the Assignment Date, any relationship between Tenant and the proposed
assignee or sublessee, and all material terms and conditions of the proposed assignment or sublease, including a copy of any proposed assignment or sublease in its final form, and such other information as Landlord may deem reasonably necessary or
appropriate to its consideration whether to grant its consent. Landlord may, by giving written notice to Tenant within 15 business days after receipt of the Assignment Notice: (i) grant such consent, (ii) refuse such consent, in its
reasonable discretion, or (iii) terminate this Lease with respect to the space described in the Assignment Notice as of the Assignment Date (an “Assignment Termination”) if the proposed assignment or subletting concerns more
than 50% of the Premises for the remainder (or substantially all of the remainder) of the Term. Among other reasons, it shall be reasonable for Landlord to withhold its consent in any of these instances: (1) the proposed assignee or subtenant
is a governmental agency; (2) in Landlord’s reasonable judgment, the use of the Premises by the proposed assignee or subtenant would entail any alterations that would lessen the value of the leasehold improvements in the Premises, or would
require increased services by Landlord; (3) in Landlord’s reasonable judgment, the proposed assignee or subtenant is engaged in areas of scientific research or other business concerns that are controversial; (4) in Landlord’s
reasonable judgment, the proposed assignee or subtenant lacks the creditworthiness to support the financial obligations it will incur under the proposed assignment or sublease; (5) in Landlord’s reasonable judgment, the character,
reputation, or business of the proposed assignee or subtenant is inconsistent with the desired tenant-mix or the quality of other tenancies in the Project or is inconsistent with the type and quality of the
nature of the Building; (6) Landlord has received from any prior landlord to the proposed assignee or subtenant a negative report concerning such prior landlord’s experience with the proposed assignee or subtenant; (7) Landlord has
experienced previous defaults by or is in litigation with the proposed assignee or subtenant; (8) the use of the Premises by the proposed assignee or subtenant will violate any applicable Legal Requirement; (9) the proposed assignee or
subtenant is an entity with whom Landlord is actively negotiating to lease space in the Project; or (10) the assignment or sublease is prohibited by Landlord’s lender. If Landlord delivers notice of its election to exercise an Assignment
Termination, Tenant shall have the right to withdraw such Assignment Notice by written notice to Landlord of such election within 10 days after Tenant’s receipt of Landlord’s notice electing to exercise the Assignment Termination. If
Tenant withdraws such Assignment Notice, this Lease shall continue in full force and effect. If Tenant does not withdraw such Assignment Notice, this Lease, and the term and estate herein granted, shall terminate as of the Assignment Date with
respect to the space described in such Assignment Notice. No failure of Landlord to exercise any such option to terminate this Lease, or to deliver a timely notice in response to the Assignment Notice, shall be deemed to be Landlord’s consent
to the proposed assignment, sublease or other transfer. Tenant shall pay to Landlord a fee equal to One Thousand Five Hundred Dollars ($1,500) in connection with its consideration of any Assignment Notice and/or its preparation or review of any
consent documents. Notwithstanding the foregoing, Landlord’s consent to a deemed assignment due.to a change in control or to an assignment of this Lease or a subletting of any portion of the
Premises to any entity controlling, controlled by or under common control with Tenant (a “Control Permitted Assignment”) shall not be required, provided that Landlord shall have the right to approve the form of any such sublease or
assignment (which approval shall not be unreasonably withheld or delayed). In addition, Tenant shall have the right to assign this Lease, upon 30 days prior written notice to Landlord but without obtaining Landlord’s prior written consent, to a
corporation or other entity which is a successor-in-interest to Tenant, 

  
 24 

 
by way of merger, consolidation or corporate reorganization, or by the purchase of all or substantially all of the assets or the ownership interests of Tenant provided that (i) such merger
or consolidation, or such acquisition or assumption, as the case may be, is for a good business purpose and not principally for the purpose of transferring the Lease, and (ii) the net worth (as determined in accordance with generally accepted
accounting principles (“GAAP”)) of the assignee is not less than the net worth (as determined in accordance with GAAP) of Tenant as of the date of Tenant’s most current quarterly or annual financial statements, and
(iii) if the resulting assignee is an entity other than Nurix, Inc., a Delaware corporation, such assignee shall agree in writing to assume all of the terms, covenants and conditions of this Lease arising after the effective date of the
assignment (a “Corporate Permitted Assignment”). Control Permitted Assignments and Corporate Permitted Assignments are hereinafter referred to as “Permitted Assignments.” Notwithstanding anything to the contrary
contained herein, Landlord shall have no right to deliver an Assignment Termination as a result of a Permitted Assignment or any notice of a Permitted Assignment from Tenant. 

(c)    Additional Conditions. As a condition to any such assignment or subletting, whether or not Landlord’s
consent is required, Landlord may require: 
 (i)    that any assignee or subtenant agree, in writing at
the time of such assignment or subletting, that if Landlord gives such party notice that Tenant is in default under this Lease, such party shall thereafter make all payments otherwise due Tenant directly to Landlord. which payments will be received
by Landlord without any liability except to credit such payment against those due under the Lease, and any such third party shall agree to attorn to Landlord or its successors and assigns should this Lease be terminated for any reason;
provided, however, in no event shall Landlord or its successors or assigns be obligated to accept such attornment; and 

(ii)    A list of Hazardous Materials, certified by the proposed assignee or sublessee to be true and
correct, which the proposed assignee or sublessee intends to use, store, handle, treat, generate in or release or dispose of from the Premises, together with copies of all documents relating to such use, storage, handling, treatment, generation,
release or disposal of Hazardous Materials by the proposed assignee or subtenant in the Premises or on the Project, prior to the proposed assignment or subletting, including, without limitation: permits; approvals; reports and correspondence;
storage and management plans; plans relating to the installation of any storage tanks to be installed in or under the Project (provided, said installation of tanks shall only be permitted after Landlord has given its written consent to do so, which
consent may be withheld in Landlord’s sole and absolute discretion); and all closure plans or any other documents required by any and all federal, state and local Governmental Authorities for any storage tanks installed in, on or under the
Project for the closure of any such tanks. Neither Tenant nor any such proposed assignee or subtenant is required, however, to provide Landlord with any portion(s) of the such documents containing information of a proprietary nature which, in and of
themselves, do not contain a reference to any Hazardous Materials or hazardous activities. 
 (d)    No Release of
Tenant, Sharing of Excess Rents. Notwithstanding any assignment or subletting, Tenant and any guarantor or surety of Tenant’s obligations under this Lease shall at all times remain fully and primarily responsible and liable for the payment
of Rent and for compliance with all of Tenant’s other obligations under this Lease. Except with respect to a Permitted Assignment, if the Rent due and payable by a sublessee or assignee (or a combination of the rental payable under such
sublease or assignment plus any bonus or other consideration therefor or incident thereto in any form attributable to the assignment or sublease) exceeds the sum of the rental payable under this Lease, (excluding however, any Rent payable under this
Section) and actual and reasonable brokerage fees, legal costs and any design or construction fees directly related to and required pursuant to the terms of any such sublease (“Excess Rent”), then Tenant shall be bound and obligated
to pay Landlord as Additional Rent hereunder 50% of such Excess Rent within 10 days following receipt thereof by Tenant. If Tenant shall sublet the Premises or any part thereof, Tenant hereby immediately and irrevocably assigns to Landlord, as
security for Tenant’s obligations under this Lease, all rent from any such subletting, and Landlord as assignee and as attorney-in-fact for Tenant, or a receiver
for Tenant appointed on Landlord’s application, may collect such rent and apply it toward Tenant’s obligations under this Lease; except that, until the occurrence of a Default, Tenant shall have the right to collect such rent. 

  
 25 

 (e)    No Waiver. The consent by Landlord to an assignment or
subletting shall not relieve Tenant or any assignees of this Lease or any sublessees of the Premises from obtaining the consent of Landlord to any further assignment or subletting nor shall it release Tenant or any assignee or sublessee of Tenant
from full and primary liability under the Lease. The acceptance of Rent hereunder, or the acceptance of performance of any other term, covenant, or condition thereof, from any other person or entity shall not be deemed to be a waiver of any of the
provisions of this Lease or a consent to any subletting, assignment or other transfer of the Premises. 

(f)    Prior Conduct of Proposed Transferee. Notwithstanding any other provision of this
Section 22, if (i) the proposed assignee or sublessee of Tenant has been required by any prior landlord, lender or Governmental Authority to take remedial action in connection with Hazardous Materials contaminating a
property, where the contamination resulted from such party’s action or use of the property in question, (ii) the proposed assignee or sublessee is subject to an enforcement order issued by any Governmental Authority in connection with the
use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including, without limitation, any order related to the failure to make a required reporting to any Governmental Authority), or (iii) because of the
existence of a pre-existing environmental condition in the vicinity of or underlying the Project, the risk that Landlord would be targeted as a responsible party in connection with the remediation of such pre-existing environmental condition would be materially increased or exacerbated by the proposed use of Hazardous Materials by such proposed assignee or sublessee, Landlord shall have the absolute right to refuse
to consent to any assignment or subletting to any such party. 
 23.    Estoppel Certificate. Tenant shall,
within 10 business days of written notice from Landlord, execute, acknowledge and deliver a statement in writing in any form reasonably requested by a proposed lender or purchaser, (i) certifying that this Lease is unmodified and in full force
and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which the rental and other charges are paid in advance, if any, (ii) acknowledging
that there are not any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (iii) setting forth such further information with respect to the status of this Lease or the Premises as may be
reasonably requested thereon. Any such statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the real property of which the Premises are a part. Tenant’s failure to deliver such statement within such
time shall be conclusive upon Tenant that the Lease is in full force and effect and without modification except as may be represented by Landlord in any certificate prepared by Landlord and delivered to Tenant for execution. 

24.    Quiet Enjoyment. So long as Tenant is not in Default under this Lease, Tenant shall, subject to the terms of
this Lease, at all times during the Term, have peaceful and quiet enjoyment of the Premises against any person claiming by, through or under Landlord. 

25.    Prorations. All prorations required or permitted to be made hereunder shall be made on the basis of a 360
day year and 30 day months. 
 26.    Rules and Regulations. Tenant shall, at all times during the Term and any
extension thereof, comply with all reasonable rules and regulations at any time or from time to time established by Landlord covering use of the Premises and the Project. The current rules and regulations are attached hereto as Exhibit E. If
there is any conflict between said rules and regulations and other provisions of this Lease, the terms and provisions of this Lease shall control. Landlord shall not have any liability or obligation for the breach of any rules or regulations by
other tenants in the Project and shall not enforce such rules and regulations in a discriminatory manner. 

27.    Subordination. This Lease and Tenants interest and rights hereunder are hereby made and shall be subject and
subordinate at all times to the lien of any Mortgage now existing or hereafter created on or against the Project or the Premises, and all amendments, restatements, renewals, 

  
 26 

 
modifications, consolidations, refinancing, assignments and extensions thereof, without the necessity of any further instrument or act on the part of Tenant; provided, however that
so long as there is no Default hereunder, Tenant’s right to possession of the Premises shall not be disturbed by the Holder of any such Mortgage. Tenant agrees, at the election of the Holder of any such Mortgage, to attorn to any such Holder.
Tenant agrees upon demand to execute, acknowledge and deliver such instruments, confirming such subordination, and such instruments of attornment as shall be requested by any such Holder, provided any such instruments contain appropriate non-disturbance provisions assuring Tenant’s quiet enjoyment of the Premises as set forth in Section 24 hereof. Notwithstanding the foregoing, any such Holder may at any time
subordinate its Mortgage to this Lease, without Tenant’s consent, by notice in writing to Tenant, and thereupon this Lease shall be deemed prior to such Mortgage without regard to their respective dates of execution, delivery or recording and
in that event such Holder shall have the same rights with respect to this Lease as though this Lease had been executed prior to the execution, delivery and recording of such Mortgage and had been assigned to such Holder. The term
“Mortgage” whenever used in this Lease shall be deemed to include deeds of trust, security assignments and any other encumbrances, and any reference to the “Holder” of a Mortgage shall be deemed to include the
beneficiary under a deed of trust. As of the date of this Lease, there is no existing Mortgage encumbering the Project. 

28.    Surrender. Upon the expiration of the Term or earlier termination of Tenant’s right of possession,
Tenant shall surrender the Premises to Landlord in the same condition as received, subject to any Alterations or Installations permitted by Landlord to remain in the Premises, free of Hazardous Materials brought upon, kept, used, stored, handled,
treated, generated in, or released or disposed of from, the Premises by any person other than a Landlord Party (collectively, “Tenant HazMat Operations”) and released of all Hazardous Materials Clearances, broom clean, ordinary wear
and tear and casualty loss and condemnation covered by Sections 18 and 19 excepted. At least 3 months prior to the surrender of the Premises, Tenant shall deliver to Landlord a narrative description of the actions proposed (or required
by any Governmental Authority) to be taken by Tenant in order to surrender the Premises (including any Installations permitted by Landlord to remain in the Premises) at the expiration or earlier termination of the Term, free from any residual impact
from the Tenant HazMat Operations and otherwise released for unrestricted use and occupancy (the “Surrender Plan”). Such Surrender Plan shall be accompanied by a current listing of (i) all Hazardous Materials licenses and
permits held by or on behalf of any Tenant Party with respect to the Premises, and (ii) all Hazardous Materials used, stored, handled, treated, generated, released or disposed of from the Premises, and shall be subject to the review and
approval of Landlord’s environmental consultant, which approval is not to be unreasonably withheld or delayed. In connection with the review and approval of the Surrender Plan, upon the request of Landlord, Tenant shall deliver to Landlord or
its consultant such additional non-proprietary information concerning Tenant HazMat Operations as Landlord shall request. On or before such surrender, Tenant shall deliver to Landlord evidence that the
approved Surrender Plan shall have been satisfactorily completed and Landlord shall have the right, subject to reimbursement at Tenant’s expense as set forth below, to cause Landlord’s environmental consultant to inspect the Premises and
perform such additional procedures as may be deemed reasonably necessary to confirm that the Premises are, as of the effective date of such surrender or early termination of the Lease, free from any residual impact from Tenant HazMat Operations.
Tenant shall reimburse Landlord, as Additional Rent, for the actual reasonable out-of pocket expense incurred by Landlord for Landlord’s environmental consultant to review and approve the Surrender Plan
and to visit the Premises and verify satisfactory completion of the same, which cost shall not exceed $2,500. Landlord shall have the unrestricted right to deliver such Surrender Plan and any report by Landlord’s environmental consultant with
respect to the surrender of the Premises to third parties. 
 If Tenant shall fail to prepare or submit a Surrender Plan approved by
Landlord, or if Tenant shall fail to complete the approved Surrender Plan, or if such Surrender Plan, whether or not approved by Landlord, shall fail to adequately address any residual effect of Tenant HazMat Operations in, on or about the Premises,
Landlord shall have the right to take such actions as Landlord may deem reasonable or appropriate to assure that the Premises and the Project are surrendered free from any residual impact from Tenant HazMat Operations, the cost of which actions
shall be reimbursed by Tenant as Additional Rent, without regard to the limitation set forth in the first paragraph of this Section 28. 

  
 27 

 Tenant shall immediately return to Landlord all keys and/or access cards to parking, the
Project, restrooms or all or any portion of the Premises furnished to or otherwise procured by Tenant. If any such access card or key is lost, Tenant shall pay to Landlord, at Landlord’s election, either the cost of replacing such lost access
card or key or the cost of reprogramming the access security system in which such access card was used or changing the lock or locks opened by such lost key. Any Tenant’s Property, Alterations and property not so removed by Tenant as permitted
or required herein shall be deemed abandoned and may be stored, removed, and disposed of by Landlord at Tenant’s expense, and Tenant waives all claims against Landlord for any damages resulting from Landlord’s retention and/or disposition
of such property. All obligations of Tenant hereunder not fully performed as of the termination of the Term, including the obligations of Tenant under Section 30 hereof, shall survive the expiration or earlier termination
of the Term, including, without limitation, indemnity obligations, payment obligations with respect to Rent and obligations concerning the condition and repair of the Premises. 

29.    Waiver of Jury Trial. TO THE EXTENT PERMITTED BY LAW, TENANT AND LANDLORD WAIVE ANY RIGHT TO TRIAL BY JURY
OR TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN LANDLORD AND TENANT ARISING OUT OF THIS LEASE OR ANY OTHER INSTRUMENT, DOCUMENT, OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION
HEREWITH OR THE TRANSACTIONS RELATED HERETO. 
 30.    Environmental Requirements. 

(a)    Prohibition/Compliance/Indemnity. Tenant shall not cause or permit any Hazardous Materials (as hereinafter
defined) to be brought upon, kept, used, stored, handled, treated, generated in or about, or released or disposed of from, the Premises or the Project in violation of applicable Environmental Requirements (as hereinafter defined) by Tenant or any
Tenant Party. If Tenant breaches the obligation stated in the preceding sentence, or if the presence of Hazardous Materials in the Premises during the Term, or any holding over results in contamination of the Premises, the Project or any adjacent
property or if contamination of the Premises, the Project or any adjacent property by Hazardous Materials brought into, kept, used, stored, handled, treated, generated in or about, or released or disposed of from, the Premises by anyone other than
Landlord and Landlord’s employees, agents and contractors otherwise occurs during the Term or any holding over, Tenant hereby indemnifies and shall defend and hold Landlord, its officers, directors, employees, agents and contractors harmless
from any and all actions (including, without limitation, remedial or enforcement actions of any kind, administrative or judicial proceedings, and orders or judgments arising out of or resulting therefrom), costs, claims, damages (including, without
limitation, punitive damages and damages based upon diminution in value of the Premises or the Project, or the loss of, or restriction on, use of the Premises or any portion of the Project), expenses (including, without limitation, attorneys’,
consultants’ and experts’ fees, court costs and amounts paid in settlement of any claims or actions), fines, forfeitures or other civil, administrative or criminal penalties, injunctive or other relief (whether or not based upon personal
injury, property damage, or contamination of, or adverse effects upon, the environment, water tables or natural resources), liabilities or losses (collectively, “Environmental Claims”) which arise during or after the Term as a
result of such contamination. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any cleanup, treatment, remedial, removal, or restoration work required
by any federal, state or local Governmental Authority because of Hazardous Materials present in the air, soil or ground water above, on, or under the Premises. Without limiting the foregoing, if the presence of any Hazardous Materials on the
Premises, the Project or any adjacent property caused or permitted by Tenant or any Tenant Party results in any contamination of the Premises, the Project or any adjacent property, Tenant shall promptly take all actions at its sole expense and in
accordance with applicable Environmental Requirements as are necessary to return the Premises, the Project or any adjacent property to the condition existing prior to the time of such contamination, provided that Landlord’s approval of such
action shall first be obtained, which approval shall not unreasonably be withheld so long as such actions would not potentially have any material adverse long-term or short-term effect on the Premises or the Project. Notwithstanding anything to the
contrary contained in Section 28 or this Section 30, Tenant shall not be responsible for, and the indemnification and hold harmless obligation set forth in this paragraph shall not apply to
(i) contamination in the Premises which Tenant can prove existed in the Premises immediately 

  
 28 

 
prior to the Commencement Date, or (ii) the presence of any Hazardous Materials in the Premises which Tenant can prove migrated from outside of the Premises into the Premises, unless in
either case, the presence of such Hazardous Materials (x) is the result of a breach by Tenant of any of its obligations under this Lease, or (y) was caused, contributed to or exacerbated by Tenant or any Tenant Party. 

(b)    Business. Landlord acknowledges that it is not the intent of this Section 30 to
prohibit Tenant from using the Premises for the Permitted Use. Tenant may operate its business according to prudent industry practices so long as the use or presence of Hazardous Materials is strictly and properly monitored according to all then
applicable Environmental Requirements. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Commencement Date a list identifying each type
of Hazardous Materials to be brought upon, kept, used, stored, handled, treated, generated on, or released or disposed of from, the Premises and setting forth any and all governmental approvals or permits required in connection with the presence,
use, storage, handling, treatment, generation, release or disposal of such Hazardous Materials on or from the Premises (“Hazardous Materials List”). Tenant shall deliver to Landlord an updated Hazardous Materials List at least once
a year listing all Hazardous Materials which Tenant is required to disclose to any Governmental Authority (e.g., the fire department) in connection with its use or occupancy of the Premises. Tenant shall deliver to Landlord true and correct
copies of the following documents (the “Haz Mat Documents”) relating to the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials prior to the Commencement Date, or if unavailable at that time,
concurrent with the receipt from or submission to a Governmental Authority: permits; approvals; reports and correspondence; storage and management plans, notice of violations of any Legal Requirements; plans relating to the installation of any
storage tanks to be installed in or under the Project (provided, said installation of tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent may be withheld in Landlord’s sole and absolute
discretion); all closure plans or any other documents required by any and all federal, state and local Governmental Authorities for any storage tanks installed in, on or under the Project for the closure of any such tanks; and a Surrender Plan (to
the extent surrender in accordance with Section 28 cannot be accomplished in 3 months). Tenant is not required, however, to provide Landlord with any -portion(s) of the
Haz Mat Documents containing information of a proprietary nature which, in and of themselves, do not contain a reference to any Hazardous Materials or hazardous activities. It is not the intent of this Section to provide Landlord with information
which could be detrimental to Tenant’s business should such information become possessed by Tenant’s competitors. 

(c)    Tenant Representation and Warranty. Tenant hereby represents and warrants to Landlord that (i) neither
Tenant nor any of its legal predecessors has been required by any prior landlord, lender or Governmental Authority at any time to take remedial action in connection with Hazardous Materials contaminating a property which contamination was permitted
by Tenant of such predecessor or resulted from Tenant’s or such predecessor’s action or use of the property in question, and (ii) Tenant is not subject to any enforcement order issued by any Governmental Authority in connection with
the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including, without limitation, any order related to the failure to make a required reporting to any Governmental Authority). If Landlord determines that
this representation and warranty was not true as of the date of this lease, Landlord shall have the right to terminate this Lease in Landlord’s sole and absolute discretion. 

(d)    Testing. Landlord shall have the right to conduct annual tests of the Premises to determine whether any
contamination of the Premises or the Project has occurred as a result of Tenant’s use. Tenant shall be required to pay the cost of such annual test of the Premises if there is violation of this Section 30 or if
contamination for which Tenant is responsible under this Section 30 is identified; provided, however, that if Tenant conducts its own tests of the Premises using third party contractors and test procedures acceptable to
Landlord which tests are certified to Landlord, Landlord shall accept such tests in lieu of the annual tests to be paid for by Tenant. In addition, at any time, and from time to time, prior to the expiration or earlier termination of the Term,
Landlord shall have the right to conduct appropriate tests of the Premises and the Project to determine if contamination has occurred as a result of Tenant’s use of the Premises. In connection with such testing, upon the request of Landlord,
Tenant shall deliver to Landlord or its consultant such non-proprietary information concerning the use of Hazardous Materials in or about the Premises by Tenant or any Tenant Party. If contamination has
occurred for which Tenant is liable under this Section 30, 

  
 29 

 
Tenant shall pay all costs to conduct such tests. If no such contamination is found, Landlord shall pay the costs of such tests (which shall not constitute an Operating Expense). Landlord shall
provide Tenant with a copy of all third party, non-confidential reports and tests of the Premises made by or on behalf of Landlord during the Term without representation or warranty and subject to a
confidentiality agreement. Tenant shall, at its sole cost and expense, promptly and satisfactorily remediate any environmental conditions identified by such testing in accordance with all Environmental Requirements. Landlord’s receipt of or
satisfaction with any environmental assessment in no way waives any rights which Landlord may have against Tenant. 

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

 (f)    Underground Tanks. If underground or other storage tanks storing Hazardous Materials located on the
Premises or the Project are used by Tenant or are hereafter placed on the Premises or the Project by Tenant, Tenant shall install, use, monitor, operate, maintain, upgrade and manage such storage tanks, maintain appropriate records, obtain and
maintain appropriate insurance, implement reporting procedures, properly close any underground storage tanks, and take or cause to be taken all other actions necessary or required under applicable state and federal Legal Requirements, as such now
exists or may hereafter be adopted or amended in connection with the installation, use, maintenance, management, operation, upgrading and closure of such storage tanks. 

(g)    Tenant’s Obligations. Tenant’s obligations under this Section 30 shall
survive the expiration or earlier termination of the Lease. During any period of time after the expiration or earlier termination of this Lease required by Tenant or Landlord to complete the removal from the Premises of any Hazardous Materials
(including, without limitation, the release and termination of any licenses or permits restricting the use of the Premises and the completion of the approved Surrender Plan), Tenant shall continue to pay the full Rent in accordance with this Lease
for any portion of the Premises not relet by Landlord in Landlord’s sole discretion, which Rent shall be prorated daily. 

(h)    Definitions. As used herein, the term “Environmental Requirements” means all applicable
present and future statutes, regulations, ordinances, rules, codes, judgments, orders or other similar enactments of any Governmental Authority regulating or relating to health, safety, or environmental conditions on, under, or about the Premises or
the Project, or the environment, including without limitation, the following: the Comprehensive Environmental Response, Compensation and Liability Act; the Resource Conservation and Recovery Act; and all state and local counterparts thereto, and any
regulations or policies promulgated or issued thereunder. As used herein, the term “Hazardous Materials” means and includes any substance, material, waste, pollutant, or contaminant listed or defined as hazardous or toxic, or
regulated by reason of its impact or potential impact on humans, animals and/or the environment under any Environmental Requirements, asbestos and petroleum, including crude oil or any fraction thereof, natural gas liquids, liquefied natural gas, or
synthetic gas usable for fuel (or mixtures of natural gas and such synthetic gas). As defined in Environmental Requirements, Tenant is and shall be deemed to be the “operator” of Tenant’s “facility” and the
“owner” of all Hazardous Materials brought on the Premises by Tenant or any Tenant Party, and the wastes, by-products, or residues generated, resulting, or produced therefrom. 

31.    Tenant’s Remedies/Limitation of Liability. Landlord shall not be in default hereunder unless Landlord
fails to perform any of its obligations hereunder within 30 days after written notice from Tenant specifying such failure (unless such performance will, due to the nature of the obligation, require a period of time in excess of 30 days, then after
such period of time as is reasonably necessary). Upon any 

  
 30 

 
default by Landlord, Tenant shall give notice by registered or certified mail to any Holder of a Mortgage covering the Premises and to any landlord of any lease of property in or on which the
Premises are located and Tenant shall offer such Holder and/or landlord a reasonable opportunity to cure the default, including time to obtain possession of the Project by power of sale or a judicial action if such should prove necessary to effect a
cure; provided Landlord shall have furnished to Tenant in writing the names and addresses of all such persons who are to receive such notices. All obligations of Landlord hereunder shall be construed as covenants, not conditions; and, except
as may be otherwise expressly provided in this Lease, Tenant may not terminate this Lease for breach of Landlord’s obligations hereunder. 

All obligations of Landlord under this Lease will be binding upon Landlord only during the period of its ownership of the Premises and not
thereafter. The term “Landlord” in this Lease shall mean only the owner for the time being of the Premises. Upon the transfer by such owner of its interest in the Premises, such owner shall thereupon be released and discharged from
all obligations of Landlord thereafter accruing, but such obligations shall be binding during the Term upon each new owner for the duration of such owner’s ownership. 

32.    Inspection and Access. Landlord and its agents, representatives, and contractors may enter the Premises at
any reasonable time to inspect the Premises and to make such repairs as may be required or permitted pursuant to this Lease. Landlord shall use reasonable efforts to minimize interruption of Tenant’s business during such inspections or repairs.
Landlord and Landlord’s representatives may enter the Premises during business hours on not less than 48 hours advance written notice (except in the case of emergencies in which case no such notice shall be required and such entry may be at any
time) for the purpose of effecting any such repairs, inspecting the Premises, showing the Premises to prospective purchasers and, during the last year of the Term, to prospective tenants or for any other reasonable business purpose. Landlord may
erect a suitable sign on the Premises stating the Premises are available to let or that the Project is available for sale. Landlord may grant easements, make public dedications, designate Common Areas and create restrictions on or about the
Premises, provided that no such easement, dedication, designation or restriction materially, adversely affects Tenant’s use or occupancy of the Premises for the Permitted Use. At Landlord’s request, Tenant shall execute such
instruments as may be necessary for such easements, dedications or restrictions. Tenant shall at all times, except in the case of emergencies, have the right to escort Landlord or its agents, representatives, contractors or guests while the same are
in the Premises, provided such escort does not materially and adversely affect Landlord’s access rights hereunder. 

33.    Security. Tenant acknowledges and agrees that security devices and services, if any, while intended to deter
crime may not in given instances prevent theft or other criminal acts and that Landlord is not providing any security services with respect to the Premises. Tenant agrees that Landlord shall not be liable to Tenant for, and 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 unauthorized entry into the Premises or any other breach of security with respect to the Premises. Tenant shall be solely
responsible for the personal safety of Tenant’s officers, employees, agents, contractors, guests and invitees while any such person is in, on or about the Premises and/or the Project. Tenant shall at Tenant’s cost obtain insurance coverage
to the extent Tenant desires protection against such criminal acts. 
 34.    Force Majeure. Except for the
payment of Rent, neither Tenant nor Landlord shall be responsible or liable for delays in the performance of its obligations hereunder when caused by, related to, or arising out of acts of God, sinkholes or subsidence, strikes, lockouts, or other
labor disputes, embargoes, quarantines, weather, national, regional, or local disasters, calamities, or catastrophes, inability to obtain labor or materials (or reasonable substitutes therefor) at reasonable costs or failure of, or inability to
obtain, utilities necessary for performance, governmental restrictions, orders, limitations, regulations, or controls, national emergencies, delay in issuance or revocation of permits, enemy or hostile governmental action, terrorism, insurrection,
riots, civil disturbance or commotion, fire or other casualty, and other similar causes or events beyond the reasonable control of such party (“Force Majeure”). 

35.    Brokers. Landlord and Tenant each represents and warrants that it has not dealt with any broker, agent or
other person (collectively, “Broker”) in connection with this transaction and that no Broker 

  
 31 

 
brought about this transaction, other than Kidder Matthews. Landlord and Tenant each hereby agree to indemnify and hold the other harmless from and against any claims by any Broker, other than
the broker, if any named in this Section 35, claiming a commission or other form of compensation by virtue of having dealt with Tenant or Landlord, as applicable, with regard to this leasing transaction. Landlord shall be
responsible for all fees of Kidder Matthews arising out of the execution of this Lease in accordance with the terms of a separate written agreement between Kidder Matthews and Landlord. 

36.    Limitation on Landlord’s Liability. NOTWITHSTANDING ANYTHING SET FORTH HEREIN OR IN ANY OTHER AGREEMENT
BETWEEN LANDLORD AND TENANT TO THE CONTRARY: (A) LANDLORD SHALL NOT BE LIABLE TO TENANT OR ANY OTHER PERSON FOR (AND TENANT AND EACH SUCH OTHER PERSON ASSUME ALL RISK OF) LOSS, DAMAGE OR INJURY, WHETHER ACTUAL OR CONSEQUENTIAL TO: TENANT’S
PERSONAL PROPERTY OF EVERY KIND AND DESCRIPTION, INCLUDING, WITHOUT LIMITATION TRADE FIXTURES, EQUIPMENT, INVENTORY, SCIENTIFIC RESEARCH, SCIENTIFIC EXPERIMENTS, LABORATORY ANIMALS, PRODUCT, SPECIMENS, SAMPLES, AND/OR SCIENTIFIC, BUSINESS,
ACCOUNTING AND OTHER RECORDS OF EVERY KIND AND DESCRIPTION KEPT AT THE PREMISES AND ANY AND ALL INCOME DERIVED OR DERIVABLE THEREFROM; (B) THERE SHALL BE NO PERSONAL RECOURSE TO LANDLORD FOR ANY ACT OR OCCURRENCE IN, ON OR ABOUT THE PREMISES OR
ARISING IN ANY WAY UNDER THIS LEASE OR ANY OTHER AGREEMENT BETWEEN LANDLORD AND TENANT WITH RESPECT TO THE SUBJECT MATTER HEREOF AND ANY LIABILITY OF LANDLORD HEREUNDER SHALL BE STRICTLY LIMITED SOLELY TO LANDLORD’S INTEREST IN THE PROJECT OR
ANY PROCEEDS FROM SALE OR CONDEMNATION THEREOF AND ANY INSURANCE PROCEEDS PAYABLE IN RESPECT OF LANDLORD’S INTEREST IN THE PROJECT OR IN CONNECTION WITH ANY SUCH LOSS; AND (C) IN NO EVENT SHALL ANY PERSONAL LIABILITY BE ASSERTED AGAINST
LANDLORD IN CONNECTION WITH THIS LEASE NOR SHALL ANY RECOURSE BE HAD TO ANY OTHER PROPERTY OR ASSETS OF LANDLORD OR ANY OF LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS. UNDER NO CIRCUMSTANCES SHALL LANDLORD OR ANY OF
LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS BE LIABLE FOR INJURY TO TENANT’S BUSINESS OR FOR ANY LOSS OF INCOME OR PROFIT THEREFROM. 

37.    Severability. If any clause or provision of this Lease is illegal, invalid or unenforceable under present or
future laws, then and in that event, it is the intention of the parties hereto that the remainder of this Lease shall not be affected thereby. It is also the intention of the parties to this Lease that in lieu of each clause or provision of this
Lease that is illegal, invalid or unenforceable, there be added, as a part of this Lease, a clause or provision as similar in effect to such illegal, invalid or unenforceable clause or provision as shall be legal, valid and enforceable. 

38.    Signs; Exterior Appearance. Tenant shall not, without the prior written consent of Landlord, which may be
granted or withheld in Landlord’s sole discretion: (i) attach any awnings, exterior lights, decorations, balloons, flags, pennants, banners, painting or other projection to any outside wall of the Project, (ii) use any curtains,
blinds, shades or screens other than Landlord’s standard window coverings, (iii) coat or otherwise sunscreen the interior or exterior of any windows, (iv) place any bottles, parcels, or other articles on the window sills,
(v) place any equipment, furniture or other items of personal property on any exterior balcony, or (vi) paint, affix or exhibit on any part of the Premises or the Project any signs, notices, window or door lettering, placards, decorations,
or advertising media of any type which can be viewed from the exterior of the Premises. Interior signs on doors and the directory tablet shall be inscribed, painted or affixed for Tenant by Landlord at the sole cost and expense of Tenant, and shall
be of a size, color and type acceptable to Landlord. Nothing may be placed on the exterior of corridor walls or corridor doors other than Landlord’s standard lettering. The directory tablet shall be provided exclusively for the display of the
name and location of tenants. 

  
 32 

 39.    Right to Extend Term. Tenant shall have the right to
extend the Term of the Lease upon the following terms and conditions: 
 (a)    Extension Rights. Tenant shall
have 1 right (an “Extension Right”) to extend the term of this Lease with respect to the Long-Term Premises only for 2 years (an “Extension Term”) on the same terms and conditions as this Lease (other than
with respect to Base Rent and the Work Letter) by giving Landlord written notice of its election to exercise the Extension Right at least 9 months prior, and no earlier than 12 months prior, to the expiration of the Base Term of the Lease. 

Upon the commencement of the Extension Term, Base Rent shall be payable at the Market Rate (as defined below). Base Rent shall thereafter be
adjusted on each annual anniversary of the commencement of such Extension Term by a percentage as determined by Landlord and agreed to by Tenant at the time the Market Rate is determined. As used herein, “Market Rate” shall mean the
then market rental rate as determined by Landlord and agreed to by Tenant. 
 If, on or before the date which is 180 days prior to the
expiration of the Base Term of this Lease, Tenant has not agreed with Landlord’s determination of the Market Rate and the rent escalations during the Extension Term after negotiating in good faith, Tenant shall be deemed to have elected
arbitration as described in Section 39(b). Tenant acknowledges and agrees that, if Tenant has elected to exercise the Extension Right by delivering notice to Landlord as required in this
Section 39(a), Tenant shall have no right thereafter to rescind or elect not to extend the term of the Lease for the Extension Term. 

Notwithstanding anything to the contrary contained in this Lease, if Tenant exercises its Extension Right pursuant to this
Section 39, upon the commencement of the Extension Term, Tenant’s Share of each earthquake deductible or occurrence of uninsured earthquake damage affecting the Premises shall not exceed $3.00 per rentable square foot
of the Premises during the first year of the Extension Term or $1.50 during the second year of the Extension Term. 

(b)    Arbitration. 

(i)    Within 10 days of Tenant’s notice to Landlord of its election (or deemed election) to arbitrate
Market Rate and escalations, each party shall deliver to the other a proposal containing the Market Rate and escalations that the submitting party believes to be correct (“Extension Proposal”). If either party fails to timely submit
an Extension Proposal, the other party’s submitted proposal shall determine the Base Rent and escalations for the Extension Term. If both parties submit Extension Proposals, then Landlord and Tenant shall meet within 7 days after delivery of
the last Extension Proposal and make a good faith attempt to mutually appoint a single Arbitrator (and defined below) to determine the Market Rate and escalations. If Landlord and Tenant are unable to agree upon a single Arbitrator, then each shall,
by written notice delivered to the other within 10 days after the meeting, select an Arbitrator. If either party fails to timely give notice of its selection for an Arbitrator, the other party’s submitted proposal shall determine the Base Rent
(including escalations) for the Extension Term. The 2 Arbitrators so appointed shall, within 5 business days after their appointment, appoint a third Arbitrator. If the 2 Arbitrators so selected cannot agree on the selection of the third Arbitrator
within the time above specified, then either party, on behalf of both parties, may request such appointment of such third Arbitrator by application to any state court of general jurisdiction in the jurisdiction in which the Premises are located,
upon 10 days prior written notice to the other party of such intent. 
 (ii)    The decision of the
Arbitrator(s) shall be made within 30 days after the appointment of a single Arbitrator or the third Arbitrator, as applicable. The decision of the single Arbitrator shall be final and binding upon the parties. The average of the two closest
Arbitrators in a three Arbitrator panel shall be final and binding upon the parties. Each party shall pay the fees and expenses of the Arbitrator appointed by or on behalf of such party and the fees and expenses of the third Arbitrator shall be
borne equally by both parties. If the Market Rate and escalations are not determined by the first day of the Extension Term, then Tenant shall pay Landlord Base Rent in an amount equal to the Base Rent in effect immediately prior to the Extension
Term and increased by the Rent Adjustment Percentage until such determination is made. After the determination of the Market Rate and escalations, the parties shall make any necessary adjustments to such payments made by Tenant. Landlord and Tenant
shall then execute an amendment recognizing the Market Rate and escalations for the Extension Term. 

  
 33 

 (iii)    An “Arbitrator” shall be any
person appointed by or on behalf of either party or appointed pursuant to the provisions hereof and: (1) shall be (A) a member of the American Institute of Real Estate Appraisers with not less than 10 years of experience in the appraisal
of improved office and high tech industrial real estate in the greater San Francisco Bay area, or (B) a licensed commercial real estate broker with not less than 15 years experience representing landlords and/or tenants in the leasing of
high tech or life sciences space in the greater San Francisco Bay area, (ii) devoting substantially all of their time to professional appraisal or brokerage work, as applicable, at the time of appointment and (iii) be in all respects
impartial and disinterested. 
 (c)    Rights Personal. The Extension Right is personal to Tenant and is not
assignable without Landlord’s consent, which may be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment of Tenant’s interest in the Lease, except that it may be assigned
in connection with any Permitted Assignment of this Lease. 
 (d)    Exceptions. Notwithstanding anything set
forth above to the contrary, at Landlord’s option, the Extension Right shall not be in effect and Tenant may not exercise the Extension Right: 

(i)    during any period of time that Tenant is in Default under any provision of this Lease; or 

(ii)    if Tenant has been in Default under any provision of this Lease 3 or more times, whether or not the
Defaults are cured, during the 12 month period immediately prior to the date that Tenant intends to exercise an Extension Right, whether or not the Defaults are cured. 

(e)    No Extensions. The period of time within which the Extension Right may be exercised shall not be
extended or enlarged by reason of Tenant’s inability to exercise the Extension Right. 
 (f)    Termination.
The Extension Right shall, at Landlord’s option, terminate and be of no further force or effect even after Tenant’s due and timely exercise of the Extension Right, if, after such exercise, but prior to the commencement date of the
Extension Term, (i) Tenant fails to timely cure any default by Tenant under this Lease; or (ii) Tenant has Defaulted 3 or more times during the period from the date of the exercise of the Extension Right to the date of the commencement of
the Extension Term, whether or not such Defaults are cured. 
 40.    Surrender of Prior Premises. If this Lease
has not been previously terminated with respect to the Prior Premises, Tenant shall voluntarily surrender the Prior Premises on or before the Prior Premises Termination Date in the condition in which Tenant is required to surrender the Premises as
of the expiration or earlier termination of this Lease and in compliance with the surrender requirements set forth in this Lease; provided, however, that Tenant shall not be required to restore any Alterations existing in the Prior Premises as of
the date of this Lease. From and after the Prior Premises Termination Date, Tenant shall have no further rights or obligations of any kind with respect to the Prior Premises. Notwithstanding the foregoing, those provisions of this Lease which, by
their terms, survive the termination of this Lease shall survive the surrender of the Prior Premises and termination of the Lease with respect to the Prior Premises as provided for herein. Nothing herein shall excuse Tenant from its obligations
under this Lease with respect to the Prior Premises prior to the Prior Premises Termination Date. 

41.    Miscellaneous. 

(a)    Notices. All notices or other communications between the parties shall be in writing and shall be deemed duly
given upon delivery or refusal to accept delivery by the addressee thereof if delivered in person, or upon actual receipt if delivered by reputable overnight guaranty courier, addressed and sent to the parties at their addresses set forth above.
Landlord and Tenant may from time to time by written notice to the other designate another address for receipt of future notices. 

  
 34 

 (b)    Joint and Several Liability. If and when included within
the term “Tenant,” as used in this instrument, there is more than one person or entity, each shall be jointly and severally liable for the obligations of Tenant. 

(c)    Financial Information. Upon Landlord’s request, Tenant shall furnish Landlord with true and complete
copies of (i) Tenant’s most recent audited annual financial statements within 90 days of the end of each of Tenant’s fiscal years during the Term, (ii) Tenant’s most recent unaudited quarterly financial statements within 45
days of the end of each of Tenant’s first three fiscal quarters of each of Tenant’s fiscal years during the Term, and (iii) any other financial information or summaries that Tenant typically provides to its lenders. Landlord shall
treat all information which Tenant provides to Landlord pursuant to this Section 41(c) as confidential information belonging to Tenant and it shall not be disclosed to any third parties other than Landlord’s auditors,
attorneys, consultants, prospective lenders, affiliates, prospective purchasers and investors and other third parties as reasonably required in the ordinary course of Landlord’s operations (so long as such parties have agreed to maintain the
confidentiality of such information). Notwithstanding the foregoing, in no event shall Tenant be required to provide any financial information to Landlord which Tenant does not otherwise prepare (or cause to be prepared) for its own purposes. 

(d)    Recordation. Neither this Lease nor a memorandum of lease shall be filed by or on behalf of Tenant in any
public record. Landlord may prepare and file, and upon request by Landlord Tenant will execute, a memorandum of lease. 

(e)    Interpretation. The normal rule of construction to the effect that any ambiguities are to be resolved
against the drafting party shall not be employed in the interpretation of this Lease or any exhibits or amendments hereto. Words of any gender used in this Lease shall be held and construed to include any other gender, and words in the singular
number shall be held to include the plural, unless the context otherwise requires. The captions inserted in this Lease are for convenience only and in no way define, limit or otherwise describe the scope or intent of this Lease, or any provision
hereof, or in any way affect the interpretation of this Lease. 
 (f)    Not Binding Until Executed. The
submission by Landlord to Tenant of this Lease shall have no binding force or effect, shall not constitute an option for the leasing of the Premises, nor confer any right or impose any obligations upon either party until execution of this Lease by
both parties. 
 (g)    Limitations on Interest. It is expressly the intent of Landlord and Tenant at all times
to comply with applicable law governing the maximum rate or amount of any interest payable on or in connection with this Lease. If applicable law is ever judicially interpreted so as to render usurious any interest called for under this Lease, or
contracted for, charged, taken, reserved, or received with respect to this Lease, then it is Landlord’s and Tenant’s express intent that all excess amounts theretofore collected by Landlord be credited on the applicable obligation (or, if
the obligation has been or would thereby be paid in full, refunded to Tenant), and the provisions of this Lease immediately shall be deemed reformed and the amounts thereafter collectible hereunder reduced, without the necessity of the execution of
any new document, so as to comply with the applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder. 

(h)    Choice of Law. Construction and interpretation of this Lease shall be governed by the internal laws of the
state in which the Premises are located, excluding any principles of conflicts of laws. 
 (i)    Time. Time is
of the essence as to the performance of Tenant’s obligations under this Lease. 
 (j)    OFAC. Tenant, and
all beneficial owners of Tenant, are currently (a) in compliance with and shall at all times during the Term of this Lease remain in compliance with the regulations of the Office 

  
 35 

 
of Foreign Assets Control (“OFAC”) of the U.S. Department of Treasury and any statute, executive order, or regulation relating thereto (collectively, the “OFAC
Rules”), (b) not listed on, and shall not during the term of this Lease be listed on, the Specially Designated Nationals and Blocked Persons List maintained by OFAC and/or on any other similar list maintained by OFAC or other governmental
authority pursuant to any authorizing statute, executive order, or regulation, and (c) not a person or entity with whom a U.S. person is prohibited from conducting business under the OFAC Rules. 

(k)    Incorporation by Reference. All exhibits and addenda attached hereto are hereby incorporated into this Lease
and made a part hereof. If there is any conflict between such exhibits or addenda and the terms of this Lease, such exhibits or addenda shall control. 

(l)    Entire Agreement. This Lease, including the exhibits attached hereto, constitutes the entire agreement
between Landlord and Tenant pertaining to the subject matter hereof and supersedes all prior and contemporaneous agreements, understandings, letters of intent, negotiations and discussions, whether oral or written, of the parties, and there are no
warranties, representations or other agreements, express or implied, made to either party by the other party in connection with the subject matter hereof except as specifically set forth herein. 

(m)    No Accord and Satisfaction. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly
installment of Base Rent or any Additional Rent will be other than on account of the earliest stipulated Base Rent and Additional Rent, nor will any endorsement or statement on any check or letter accompanying a check for payment of any Base Rent or
Additional Rent be an accord and satisfaction. Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or to pursue any other remedy provided in this Lease. 

(n)    Hazardous Activities. Notwithstanding any other provision of this Lease, Landlord, for itself and its
employees, agents and contractors, reserves the right to refuse to perform any repairs or services in any portion of the Premises which, pursuant to Tenant’s routine safety guidelines, practices or custom or prudent industry practices, require
any form of protective clothing or equipment other than safety glasses. In any such case, Tenant shall contract with parties who are acceptable to Landlord, in Landlord’s reasonable discretion, for all such repairs and services, and Landlord
shall, to the extent required, equitably adjust Tenant’s Share of Operating Expenses in respect of such repairs or services to reflect that Landlord is not providing such repairs or services to Tenant. 

(o)    Mission Bay Requirements. Tenant acknowledges and agrees that the use and operation of the Project are
governed by, among other things, the requirements and disclosures set forth on Exhibit H attached hereto.

 FIRST AMENDMENT TO LEASE 

THIS FIRST AMENDMENT TO LEASE (this “First Amendment”) is made as of October 03, 2014, by and between ARE-SAN FRANCISCO NO. 26, LLC, a Delaware limited liability company (“Landlord”), and NURIX, INC., a Delaware corporation (“Tenant”). 

RECITALS 

A.    Landlord and Tenant are now parties to that certain Lease Agreement dated as of March 24, 2014, as
amended by that certain letter agreement dated April 15, 2014 (as amended, the “Lease”). Pursuant to the Lease, Tenant leases certain premises in a building located at 1700 Owens Street, San Francisco, California. The premises
are more particularly described in the Lease. Capitalized terms used herein without definition shall have the meanings defined for such terms in the Lease. 

B.    As of the date of this first Amendment, Tenant is occupying the Month-to-Month Premises consisting of approximately 9,614 rentable square feet. 

C.    Landlord and Tenant desire, subject to the terms and conditions set forth below, to amend the Lease to, among
other things, (i) expand the size of the Month-to-Month Premises and the Long-Term Premises, respectively, by adding that portion of the Building commonly known as
Suite 240 containing approximately 2,039 rentable square feet, as shown on Exhibit A attached to this First Amendment (the “Expansion Premises”), and (ii) to add the Prior Premises as part of the Long-Term Premises,

 NOW, THEREFORE, in consideration of the foregoing Recitals, which are incorporated herein by this reference, the mutual promises
and conditions contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows: 

 

	1.	 Expansion Premises. Commencing on the Expansion Premises Commencement Date (as defined
below), Landlord leases to Tenant, and Tenant leases from Landlord, the Expansion Premises. 

  

	2.	 Delivery. Landlord shall use reasonable efforts to deliver (“Delivery” or
“Deliver”) the Expansion Premises to Tenant on or before the Target Expansion Premises Commencement Date. The “Target Expansion Premises Commencement Date” shall be January 15, 2015. For the avoidance of any
doubt, Landlord is not required to construct any improvements in the Expansion Premises. If Landlord fails to timely Deliver the Expansion Premises, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and the Lease
with respect to the Expansion Premises shall not be void or voidable except as provided herein. If Landlord does not Deliver the Expansion Premises within 90 days of the Target Expansion Premises Commencement Date for any reason other than Force
Majeure delays, the Lease with respect to the Expansion Premises only may be terminated by Tenant by written notice to the Landlord, and if so terminated by Tenant: (a) the additional Security Deposit provided for in
Section 7, or any balance thereof (i.e., after deducting therefrom all amounts to which Landlord is entitled under the provisions of the Lease), shall be returned to Tenant (i.e., if the additional Security Deposit was in
the form of an additional Letter of Credit, Landlord shall return the additional Letter of Credit to Tenant or if the additional Security Deposit was in the form of an amended Letter of Credit, Landlord shall reasonably cooperate with Tenant,
at no cost to Landlord, to further amend the amended Letter of Credit to reduce such Letter of Credit to its original amount), and (b) neither Landlord nor Tenant shall have any further rights, duties or obligations with respect to the
Expansion Premises, except with respect to provisions which expressly survive termination of the Lease. For the avoidance of doubt, if the Lease is terminated pursuant to this paragraph with respect to the Expansion Premises, all of the provisions
of this First Amendment shall be null and void and of no further force or effect and the parties shall enter into an amended and restated version of this First Amendment providing for,

	 	
among other things, (i) the inclusion of the Prior Premises as part of the Long-Term Premises commencing on the Long-Term Premises Commencement Date, and (ii) the adjustment of the
Tenant Improvement Allowance and the Additional Tenant Improvement Allowance to $670,225, respectively. If Tenant does not elect to terminate the Lease with respect to the Expansion Premises within 5 business days of the lapse of such 90 day period,
such right to terminate the Lease with respect to the Expansion Premises shall be waived and this Lease shall remain in full force and effect. 

The “Expansion Premises Commencement Date” shall be the date that Landlord Delivers the Expansion Premises to Tenant in
vacant, broom clean condition. Upon the request of Landlord, Tenant shall execute and deliver a written acknowledgment of the Expansion Premises Commencement Date in substantially the form of the “Acknowledgement of Commencement Date”
attached to the Lease as Exhibit D; provided, however, Tenant’s failure to execute and deliver such acknowledgment shall not affect Landlord’s rights hereunder. 

For the period of 60 consecutive days after the Expansion Premises Commencement Date, Landlord shall, at its sole cost and expense (which shall
not constitute an Operating Expense), be responsible for any repairs that are required to be made to the Building Systems serving the Expansion Premises, unless Tenant or any Tenant Party was responsible for the cause of such repair, in which case
Tenant shall pay the cost. 
 Except as otherwise set forth in this First Amendment: (i) Tenant shall accept the Expansion Premises in
their condition as of the Expansion Premises Commencement Date, subject to all applicable Legal Requirements; (ii) Landlord shall have no obligation for any defects in the Expansion Premises; and (iii) Tenant’s taking possession of
the Expansion Premises shall be conclusive evidence that Tenant accepts the Expansion Premises and that the Expansion Premises were in good condition as of the Expansion Premises Commencement Date. 

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

Premises and Rentable Area of Long-Term Premises. Commencing on the Expansion Premises Commencement Date, the defined terms “Premises” and “Rentable Area of Month-to Month

payable under the Other Lease in connection with the Additional TI Allowance (as defined in the Other Lease) pursuant to Section 5(b) below, and (2) those provisions of the Other Lease which, by their terms survive the
termination of the Other Lease 

  
 F-1 

 
shall survive the termination of the Other Lease provided for herein; provided, however, Landlord and Tenant acknowledge and agree that Tenant’s continued occupancy of the Initial Second
Amendment Expansion Premises shall be pursuant to the Lease and not as a holdover under the Other Lease and Tenant shall not be required to vacate or surrender the Initial Second Amendment Expansion Premises. Because Tenant will continue to occupy
the Initial Second Amendment Expansion Premises under the Lease, Tenant shall not be required to deliver a Surrender Plan under the Other Lease in connection with the expiration of the Other Lease. 

Upon the request of Landlord, Tenant shall execute and deliver a written acknowledgment of the Initial Second Amendment Expansion Premises
Commencement Date in substantially the form of the “Acknowledgement of Commencement Date” attached to the Lease as Exhibit D; provided, however, Tenant’s failure to execute and deliver such acknowledgment shall
not affect Landlord’s rights hereunder. 
 For the period of 60 consecutive days after the Initial Second Amendment Expansion Premises
Commencement Date, Landlord shall, at its sole cost and expense (which shall not constitute an Operating Expense), be responsible for any repairs that are required to be made to the Building Systems serving the Existing Premises and the Initial
Second Amendment Expansion Premises, unless Tenant or any Tenant Party was responsible for the cause of such repair, in which case Tenant shall pay the cost. 

Except as otherwise set forth in this Second Amendment: (i) Landlord shall have no obligation for any defects in the Initial Second
Amendment Expansion Premises; and (iii) Tenant’s occupancy of the Initial Second Amendment Expansion Premises prior to the Initial Second Amendment Expansion Premises Commencement Date pursuant to the Other Lease shall be conclusive
evidence that Tenant accepts the Initial Second Amendment Expansion Premises and that the Initial Second Amendment Expansion Premises were in good condition at the time Tenant took possession of the Initial Second Amendment Expansion Premises. 

b.    Subsequent Second Amendment Expansion Premises. The “Subsequent Second Amendment Expansion Premises
Commencement Date” shall be the day immediately after the date that the Gladstone Lease terminates, which is expected to occur on January 15, 2019. Upon the request of Landlord, Tenant shall execute and deliver a written acknowledgment
of the Subsequent Second Amendment Expansion Premises Commencement Date in substantially the form of the “Acknowledgement of Commencement Date” attached to the Lease as Exhibit D; provided, however, Tenant’s
failure to execute and deliver such acknowledgment shall not affect Landlord’s rights hereunder. 
 Landlord and Tenant acknowledge that
Tenant has occupied and, as of the date of this Second Amendment, continues to occupy the Subsequent Second Amendment Expansion Premises pursuant to a sublease agreement (“Gladstone Sublease”) between Tenant and The David J.
Gladstone Institutes (“Gladstone”), which Gladstone Sublease is subject to the terms of that certain Lease Agreement between Landlord and Gladstone dated as of January 8, 2007 (as the same has been and may in the future be
amended, the “Gladstone Lease”). 
 Tenant acknowledges that Gladstone has the right under the Gladstone Lease to extend the
term of the Gladstone Lease beyond January 15, 2019. If Gladstone exercises its right to extend the term of the Gladstone Lease, the Subsequent Second Amendment Expansion Premises Commencement Date shall not occur until the term of the
Gladstone Lease terminates. Landlord agrees that it shall not agree to extend the Gladstone Lease with respect to the Subsequent Second Amendment Expansion Premises except pursuant to the terms of the extension right currently set forth in the
Gladstone Lease if Gladstone properly exercises such right. Landlord shall have no liability whatsoever to Tenant relating to or arising from the failure of the Subsequent Second Amendment Expansion Premises Commencement Date to occur as a result of
Gladstone’s election to extend the term of the Gladstone Lease pursuant to the extension right currently set forth in the Gladstone Lease if Gladstone properly exercises such right. Landlord and Tenant acknowledge

  
 F-2 

 
and agree that commencing on the Subsequent Second Amendment Expansion Premises Commencement Date, Tenant’s continued occupancy of the Subsequent Second Amendment Expansion Premises after
the termination of the Gladstone Lease shall be pursuant to the Lease and shall not be a hold over under the Gladstone Lease. 
 Landlord and
Tenant agree that if the Gladstone Lease terminates prior to January 15, 2019, then, notwithstanding anything to the contrary contained in the Lease, the Subsequent Second Amendment Expansion Premises Commencement Date shall be amended to be
the day immediately after the date of such early termination of the Gladstone Lease (“Early Commencement Date”); provided, however, that Tenant shall, commencing on the Early Commencement Date through January 14, 2019, be
required to pay (a) monthly Base Rent at the rate payable by Tenant under the Gladstone Sublease, and (b) Tenant’s Share of Operating Expenses pursuant to the terms of this Lease. Notwithstanding the foregoing, if the early
termination of the Gladstone Lease was due to a casualty or condemnation, then such casualty or condemnation shall be deemed to have occurred during the Term of this Lease and the rights and obligations of Landlord and Tenant with respect to the
Lease shall be governed by Section 18 and Section 19 of the Lease, as applicable. 
 For
the period of 60 consecutive days after the Subsequent Second Amendment Expansion Premises Commencement Date, Landlord shall, at its sole cost and expense (which shall not constitute an Operating Expense), be responsible for any repairs that are
required to be made to the Building Systems serving the Subsequent Second Amendment Expansion Premises, unless Tenant or any Tenant Party was responsible for the cause of such repair, in which case Tenant shall pay the cost. 

Except as otherwise set forth in this Second Amendment: (i) Landlord shall have no obligation for any defects in the Subsequent Second
Amendment Expansion Premises; and (iii) Tenant’s occupancy of the Subsequent Second Amendment Expansion Premises prior to the Subsequent Second Amendment Expansion Premises Commencement Date pursuant to the Gladstone Sublease shall be
conclusive evidence that Tenant accepts the Subsequent Second Amendment Expansion Premises and that the Subsequent Second Amendment Expansion Premises were in good condition at the time Tenant took possession of the Subsequent Second Amendment
Expansion Premises. 
 c.    General. Except as otherwise provided in this Second Amendment, Tenant agrees and
acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty with respect to the condition of all or any portion of the Initial Second Amendment Expansion Premises, the Subsequent Second Amendment Expansion
Premises and/or the suitability of the Initial Second Amendment Expansion Premises or the Subsequent Second Amendment Expansion Premises for the conduct of Tenant’s business, and Tenant waives any implied warranty that the Initial Second
Amendment Expansion Premises or the Subsequent Second Amendment Expansion Premises are suitable for the Permitted Use.

	6.	 Definition of Tenant’s Share of Operating Expenses. 

a.    Commencing on the Initial Second Amendment Expansion Premises Commencement Date, the defined terms
“Tenant’s Share of Operating Expenses for Month-to-Month Premises” and “Tenant’s Share of Operating Expenses for Long-Term
Premises” on page 2 of the Lease are deleted in their entirety and replaced with the following:

$1.50 per rentable square foot of the Premises. Following earthquake damage to the Project, Tenant shall pay Tenant’s Share of any such deductible or uninsured damage in equal monthly installments (not to exceed the Deductible Cap) amortized
over the remaining balance of the Base Term. 
  

	7.	 Second Amendment Tenant Improvements. Tenant shall have the right to construct certain
tenant improvements in the Premises (the “Second Amendment Tenant Improvements”) subject to the terms of the “Second Amendment Work Letter” attached hereto as Exhibit C. Commencing on the mutual execution and
delivery of this Second Amendment by the parties, Landlord shall make the TI Allowance (as defined in the Second Amendment Work Letter) available to Tenant for the design and construction of the Second Amendment Tenant Improvements, as provided in
the Second Amendment Work Letter. Notwithstanding anything to the contrary contained in the Lease, Tenant shall not be required to remove the Second Amendment Tenant Improvements or any other improvements existing in the Existing Premises, the
Initial Second 

  
 F-5 

	 	
Amendment Expansion Premises or the Subsequent Second Amendment Expansion Premises as of the date of this Second Amendment at the expiration or earlier termination of the Term, nor shall Tenant
have the right to remove any of the Second Amendment Tenant Improvements or any other improvements existing in the Existing Premises, the Initial Second Amendment Expansion Premises or the Subsequent Second Amendment Expansion Premises as of the

fully amortize the portion of the Additional Tenant Improvement Allowance actually funded by Landlord, if any, in equal monthly payments with interest at a rate of 9% per annum, which interest shall begin to accrue on the date that Landlord first
disburses the applicable portion of such Additional Tenant Improvement Allowance. Tenant acknowledges that because the Additional Tenant Improvement Allowance may be disbursed to Tenant in multiple disbursements following the Commencement Date, the
Additional Rent payable by Tenant pursuant to this Section 8 may be adjusted following each such disbursement. Any of the Additional Tenant Improvement Allowance and applicable interest remaining unpaid as of the expiration
or earlier termination of the Lease shall be paid to Landlord in a lump sum at the expiration or earlier termination of this Lease. 

  

	9.	 Expansion Right. 

a.    Generally. Subject to the superior right of Gladstone and the subtenant occupying the First Floor Space as of
the date of this Second Amendment as to such space (“Existing Subtenant”), Tenant shall have the one-time right, but not the obligation, to expand the Premises to include the First Floor Space
upon the terms and conditions set forth in this Section 9 (the “Right of First Offer”). For the purposes of this Section 9(a), “First Floor Space” shall mean that
certain space on the first floor of the Building more particularly described on Exhibit D attached hereto. If the First Floor Space becomes available for lease to a third party other than the Existing Subtenant, Landlord shall, at such
time as Landlord shall elect so long as Tenant’s rights hereunder are preserved, deliver to Tenant written notice (the “Expansion Notice”) of the availability of the First Floor Space together with the terms and conditions on
which Landlord is prepared to lease to Tenant to First Floor Space, which Tenant acknowledges may include a term of lease for the First Floor Space which may not be co-terminous with the Term of the Lease with
respect to the Premises. Tenant shall be entitled to exercise its right under this Section 9(a) only with respect to the entire First Floor Space identified in the Expansion Notice. Tenant shall have 5 business days
following delivery to Tenant of the Expansion Notice to deliver to Landlord written notification of Tenant’s exercise of the Right of First Offer (the “Acceptance Notice”). If Tenant fails to deliver an Acceptance Notice to
Landlord within the required 5 business day period, Landlord shall have the right to lease the First Floor Space to any third party on terms acceptable to Landlord, in its sole and absolute discretion, and Tenant shall be deemed to have waived its
rights under this Section 9(a). Notwithstanding the foregoing, if Landlord negotiates with a third party economic lease terms materially more favorable (but in no event shall the economic lease terms be considered more
favorable unless the difference in net effective base rent is 5% or greater) than those offered to Tenant in the Expansion Notice, Landlord shall be required to submit the more favorable economic terms to Tenant for its review. Tenant shall have 5
business days after receipt of the more favorable terms to accept or reject the revised terms. If Tenant rejects the more favorable terms, Landlord shall have the right to lease the First Floor Space to any third party on terms acceptable to
Landlord, in its sole and absolute discretion, and Tenant shall be deemed to have waived its rights under this Section 9(a). 

  
 F-6 

 b.    Amended Lease. If: (i) Tenant fails to timely
deliver an Acceptance Notice, or (ii) after the expiration of a period of 10 days after Landlord’s delivery to Tenant of a lease amendment for Tenant’s lease of the First Floor Space, no lease amendment for the First Floor Space
acceptable to both parties each in their reasonable discretion, has been executed, Tenant shall, notwithstanding anything to the contrary contained herein, be deemed to have waived its right to lease the First Floor Space. 

c.    Exceptions. Notwithstanding the above, the Expansion Right shall, at Landlord’s option, not be in effect
and may not be exercised by Tenant: 
 (i)    during any period of time that Tenant is in Default under
any provision of the Lease; or 
 (ii)    if Tenant has been in Default under any provision of the Lease
3 or more times, whether or not the Defaults are cured, during the 12 month period prior to the date on which Tenant seeks to exercise the Expansion Right. 

d.    Termination. The Expansion Right shall, at Landlord’s option, terminate and be of no further force or
effect even after Tenant’s due and timely exercise of the Expansion Right, if, after such exercise, but prior to the commencement date of the lease of the First Floor Space, (i) Tenant fails to timely cure any default by Tenant under the
Lease; or (ii) Tenant has Defaulted 3 or more times during the period from the date of the exercise of the Expansion Right to the date of the commencement of the lease of the First Floor Space, whether or not such Defaults are cured. 

e.    Subordinate. Tenant hereby acknowledges and agrees that, notwithstanding anything to the contrary contained in
the Lease, Tenant’s Expansion Right shall be subject and Gladstone’s rights to extend the term of its lease with respect to the First Floor Space and any election by the Existing Subtenant to remain in the First Floor Space after the
expiration of its sublease pursuant to a direct lease with Landlord. 
 f.    Rights Personal. The Expansion Right
is personal to Tenant and is not assignable without Landlord’s consent, which may be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment of Tenant’s interest in the Lease,
except that it may be assigned in connection with any Permitted Assignment of the Lease. 
 g.    No Extensions.
The period of time within which the Expansion Right may be exercised shall not be extended or enlarged by reason of Tenant’s inability to exercise the Expansion Right. 
  

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

  

	11.	 California Accessibility Disclosure. For purposes of Section 1938(a) of the
California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project has not undergone inspection by a Certified Access Specialist (CASp). In addition, the following notice is hereby provided pursuant to
Section 1938(e) of the California Civil Code: “A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards
under state law. Although state law does not require a CASp inspection of the subject premises, the commercial 

  
 F-7 

	 	
property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if
requested by the lessee or tenant. The parties shall mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct
violations of construction-related accessibility standards within the premises.” In furtherance of and in connection with such notice: (i) Tenant, having read such notice and understanding Tenant’s right to request and obtain a CASp
inspection, hereby elects not to obtain such CASp inspection and forever waives its rights to obtain a CASp inspection with respect to the Premises, Building and/or Project to the extent permitted by Legal Requirements; and (ii) if the waiver
set forth in clause (i) hereinabove is not enforceable pursuant to Legal Requirements, then Landlord and Tenant hereby agree as follows (which constitute the mutual agreement of the parties as to the matters described in the last sentence of
the foregoing notice): (A) Tenant shall have the one-time right to request for and obtain a CASp inspection, which request must be made, if at all, in a written notice delivered by Tenant to Landlord;
(B) any CASp inspection timely requested by Tenant shall be conducted (1) at a time mutually agreed to by Landlord and Tenant, (2) in a professional manner by a CASp designated by Landlord and without any testing that would damage the
Premises, Building or Project in any way, and (3) at Tenant’s sole cost and expense, including, without limitation, Tenant’s payment of the fee for such CASp inspection, the fee for any reports prepared by the CASp in connection with
such CASp inspection (collectively, the “CASp Reports”) and all other costs and expenses in connection therewith; (C) the CASp Reports shall be delivered by the CASp simultaneously to Landlord and Tenant; (D) Tenant, at
its sole cost and expense, shall be responsible for making any improvements, alterations, modifications and/or repairs to or within the Premises as and to the extent required by Legal Requirements to correct violations of construction-related
accessibility standards including, without limitation, any violations disclosed by such CASp inspection; and (E) if such CASp inspection identifies any improvements, alterations, modifications and/or repairs necessary to correct violations of
construction-related accessibility standards relating to those items of the Building and Project located outside the Premises that are Landlord’s obligation to repair as set forth in the Lease, then Landlord shall perform such improvements,
alterations, modifications and/or repairs as and to the extent then required by Legal Requirements to correct such violations, and Tenant shall reimburse Landlord for the cost of such improvements, alterations, modifications and/or repairs within 10
business days after Tenant’s receipt of an invoice therefor from Landlord. 

  

	12.	 Brokers. Landlord and Tenant each represents and warrants that it has not dealt with any
broker, agent or other person (collectively, “Broker”) in connection with the transaction reflected in this Second Amendment and that no Broker brought about this transaction, other than CBRE. Landlord and Tenant each hereby agree
to indemnify and hold the other harmless from and against any claims by any Broker, other than CBRE, claiming a commission or other form of compensation by virtue of having dealt with Tenant or Landlord, as applicable, with regard to this Second
Amendment. 

  

	13.	 Environmental. Notwithstanding anything to the contrary contained in
Section 28 or Section 30 of the Lease, Tenant shall not be responsible for, and the indemnification and hold harmless obligation set forth in Section 30(a) of the Lease
shall not apply to (i) contamination in the Initial Second Amendment Expansion Premises which Tenant can prove existed in the Initial Second Amendment Expansion Premises prior to Tenant’s occupancy of the Initial Second Amendment Expansion
Premises, (ii) contamination in the Subsequent Second Amendment Expansion Premises which Tenant can prove existed in the Subsequent Second Amendment Expansion Premises prior to Tenant’s occupancy of the Subsequent Second Amendment
Expansion Premises, or (ii) the presence of any Hazardous Materials in the Initial Second Amendment Expansion Premises or the Subsequent Second Amendment Expansion Premises which Tenant can prove migrated from outside of the Initial Second
Amendment Expansion Premises or the Subsequent Second Amendment Expansion Premises, as applicable, into the Initial Second Amendment Expansion Premises or the Subsequent Second Amendment Expansion Premises, unless in any case, the presence of such
Hazardous Materials (x) is the result of a breach by Tenant of any of its obligations under the Lease, or (y) was caused, contributed to or exacerbated by Tenant or any Tenant Party. 

  
 F-8 

	14.	 Extension Right. For the avoidance of doubt, Tenant’s Extension Right pursuant to
Section 39 of the Lease (as amended by this Second Amendment) shall apply to the Existing Premises, the Initial Second Amendment Expansion Premises and, following the Subsequent Second Amendment Expansion Premises
Commencement Date, the Subsequent Second Amendment Expansion Premises, and Tenant shall be required to exercise its Extension Right with respect to the entire Premises being leased by Tenant at the time that Tenant exercises such Extension Right
(i.e., the Existing Premises, the Initial Second Amendment Expansion Premises and the Subsequent Second Amendment Expansion Premises).

Charge Adjustment Date shall be May 1st of each year.

credit and $25,000 is in the form of cash, and a cash security deposit of $59,721.30 under the Other Lease (the “Other Lease Security”). As of the Initial Second Amendment Expansion Premises Commencement Date, Landlord shall hold
the Other Lease Security as part of the Security Deposit under the Lease. 
  

	17.	 FF&E. During the Term, Tenant shall, to the extent that such FF&E actually exists
in the Initial Second Amendment Expansion Premises as of the Initial Second Amendment Expansion Premises Commencement Date continue to have the right to use the furniture, fixtures and equipment located in the Initial Second Amendment Expansion
Premises and more particularly described on Exhibit E attached hereto (the “FF&E”). Tenant has used the FF&E pursuant to the terms of the Other Lease prior to the Second Amendment Expansion Premises Commencement Date
and Tenant continues to accept the FF&E in its condition as of the Initial Second Amendment Expansion Premises Commencement Date, and Landlord shall have no obligation for any defects in the FF&E. Landlord, at no cost to Tenant, shall remove
any furniture and appliances (such as private office furniture, cubicle furniture, file cabinets, tables, desks, credenzas and chairs) included as part of the FF&E from the Initial Second Amendment Expansion Premises as Tenant may request from
time to time.

a.    License. Commencing on the Initial Second Amendment Expansion Premises Commencement Date, Landlord hereby
grants to Tenant, and Tenant hereby accepts, a non-exclusive license (“License”) to use that certain portion of the 4th floor of the

rights of any other tenants, other licensees or Landlord’s service providers. Landlord assumes no responsibility for enforcing Tenant’s rights or for protecting the Shared Area from interference or use from any person including, without
limitation, other tenants or licensees of the Project. Landlord may, at Landlord’s option, terminate the License granted to Tenant hereunder at any time during the Term following a Default of Tenant under the Lease. The terms of
Section 16 of the Lease shall apply with respect to the Shared Area as though the Shared Area were a portion of the Premises. 

  
 F-9 

 c.    Relocation and Modification of Shared Area. Tenant
acknowledges and agrees that Landlord shall have the right at any time and from time to time to reconfigure, relocate to another space on the 4th floor of the Building or modify the Shared Area
and/or to revise or expand any of the services (if any) provided therein, and to add, change, reconfigure or relocate any of the Equipment (as hereinafter defined) located therein (so long as the Equipment continues to include a glass wash, ice
machine and autoclave (the “Required Equipment”). 
 d.    Waiver. 

(i)    Landlord’s sole obligation for providing any equipment, systems, furnishings or personal

delays thereto due to the inability to obtain parts or replacements, Landlord shall have no obligation to provide Tenant with alternative or back-up Equipment. Tenant expressly acknowledges and agrees that
Landlord does not guaranty that the Equipment will be operational at all times, will function or perform adequately and Landlord shall not be liable for any damages resulting from the failure of such Equipment. 

(ii)    Tenant acknowledges and agrees that there are no warranties of any kind, whether express or
implied, made by Landlord or otherwise with respect to the Shared Area or any Equipment or services (if any) provided therein, and Tenant disclaims any and all such warranties. 

(iii)    Tenant acknowledges and agrees that Landlord is under no obligation to provide to Tenant (or any
other parities entitled to use the Shared Area) any type of instruction or implement any training programs relating to the use of the Shared Area or any Equipment; provided, however, Tenant shall cause its employees who will be using
