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. 

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 twenty three million nine hundred sixty eight thousand (23,968,000) 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 twenty three million nine
hundred sixty eight thousand (23,968,000) shares of Common Stock.  
 (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.    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. 

  
 4. 

 (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; 

(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 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 

  
 6. 

 
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 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 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 

  
 7. 

 
than thirty (30) days 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. 

(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 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 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 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 

  
 8. 

 
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. 

(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. 

  
 9. 

 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 requirements of Section 409A of the Code. Such restrictions, if any, shall be determined by the Board and contained in the Restricted Stock Unit Award
Agreement evidencing such Restricted Stock Unit Award. For example, such restrictions may include, without limitation, a requirement that any Common Stock that is to be issued in a year following the year in which the Restricted Stock Unit Award

 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. 

(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 

  
 12. 

 
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 

  
 14. 

 
exemption provided by Rule 12h-1(f), the 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 3(a), (ii) the class(es) and maximum number of securities that may be issued pursuant to the exercise of Incentive
Stock Options pursuant to Section 3(c), 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. 

  
 15. 

 (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: 

(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 PLAN. 
 (a)    Plan Term. The Board may suspend or
terminate the Plan at any time. Unless sooner terminated 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. 

  
 16. 

 (b)    No Impairment of Rights. 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.

12.    CHOICE OF LAW.

transaction, as that term is used in Statement of Financial Accounting Standards No. 123 (revised). Notwithstanding the foregoing, the conversion of any convertible securities of the Company shall not be treated as a Capitalization Adjustment.

 (d)    “Cause” shall have the meaning ascribed to such term in any
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
Participant’s commission of any felony or any crime involving fraud, dishonesty or moral turpitude under the laws of the United States or any state thereof; (ii) such Participant’s attempted commission of, or participation in, a fraud
or act of dishonesty against the Company; (iii) such Participant’s intentional, material violation of any contract or agreement between the Participant and the Company or of any statutory duty owed to the Company; (iv) such
Participant’s unauthorized use or disclosure of the Company’s confidential information or trade secrets; or (v) such Participant’s gross misconduct. The determination that a termination of the Participant’s Continuous
Service is either for Cause or without Cause shall be made by the Company in its sole discretion. Any determination by the Company that the Continuous Service of a Participant was terminated with or without Cause for the purposes of outstanding

occurrence, in a single transaction or in a series of related transactions, of any one or more of the following events: 

(i)    any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing
more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a Change in Control shall
not be deemed to occur (A) on account of the acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities 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 percentage of the then outstanding voting securities Owned
by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur; 

(ii)    there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the
Company and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities
representing more than fifty percent (50%) of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%) of the combined
outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company
immediately prior to such transaction;

disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries
to an Entity, more than fifty percent (50%) of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting
securities of the Company immediately prior to such sale, lease, license or other disposition; or

Board, are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the appointment or
election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member shall, for purposes of this Plan, be considered as a member of
the Incumbent Board. 
 Notwithstanding the foregoing definition or any other provision of this Plan, (A) the term Change in 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 agreement between the
Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Stock Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in

Director, or payment of a fee for such service, shall not cause a Director to be considered a “Consultant” for purposes of the Plan.  

(k)    “Continuous Service” means that the Participant’s service with the Company or an
Affiliate, whether as 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 purposes of vesting in a Stock Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or
as otherwise required by law.

 PERSONALIS, INC. 

2011 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, Personalis, Inc. (the
“Company”) has granted you an option under its 2011 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; 

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 

  
 25. 

 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: 
 1) 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. 
 2)
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. 

3) 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. 

  
 26. 

 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. 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.

  
 27. 

 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. 

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. 

  
 28. 

 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. 
 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 

  
 29. 

 
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. 

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.

 PERSONALIS, INC. 

EARLY EXERCISE STOCK PURCHASE AGREEMENT 

UNDER THE 2011 EQUITY INCENTIVE PLAN 

THIS AGREEMENT is made by and between PERSONALIS,
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 2011 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: 
 18. 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. 
 19. 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. 

  
 33. 

 20. 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”). For convenience, the Vesting Schedule set forth in the Stock Option Grant Notice. 
 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 (the “Repurchase Price”). No interest shall be paid with respect to and no other adjustments (other than
adjustments in accordance with the Plan to reflect stock splits and similar changes in capitalization) shall be made to the Repurchase Price. The closing of any repurchase under this Section 3 shall be at a date to be specified by the Company,
such date to be no later than 90 days after Purchaser’s termination date. The Repurchase Price shall be paid at the closing in the form of a check or by cancellation of money purchase indebtedness. 

c. To exercise the Repurchase Option, the Company shall give written notice thereof to Purchaser (the “Repurchase
Notice”). The Repurchase Notice is irrevocable by the Company and shall (i) be in writing and signed by an authorized officer of the Company, (ii) set forth the Company’s intent to exercise the Repurchase Option and
contain the total number of Unvested Shares to be sold to the Company pursuant to the exercise of the Repurchase Option, (iii) be mailed or delivered to Purchaser at Purchaser’s address reflected or last reflected on the Company’s
payroll records or delivered to Purchaser in person, and (iv) be so mailed or delivered no later than the ninetieth (90th) day following Purchaser’s termination date. If mailed, the
Repurchase Notice shall be enclosed in a properly sealed envelope, addressed as aforesaid, and deposited (postage prepaid) in a post office or branch post office regularly maintained by the United States Government. The Repurchase Notice shall be
deemed to have been duly given as of the date mailed or delivered in accordance with the foregoing provisions. 
 d. Upon a repurchase
of any Unvested Shares by the Company, such repurchased Unvested Shares shall be automatically transferred to the Company, without any further action by Purchaser (or Purchaser’s beneficiary or personal representative, as the case may be). The
Company may exercise its powers under this Early Exercise Stock Purchase Agreement and take any other action necessary or advisable to evidence such transfer. Purchaser (or Purchaser’s beneficiary or personal representative, as the case may be)
must deliver any additional documents of transfer that the Company may request to confirm the transfer of such repurchased Unvested Shares to the Company. 

  
 34. 

 e. If Purchaser (or any permitted transferee who is an employee of the Company or any
Affiliate) ceases to be an employee of the Company or any of its Affiliates and holds Unvested Shares as to which the Company’s Repurchase Option has been exercised, Purchaser shall be entitled to payment in respect of such Unvested Shares in
accordance with the foregoing provisions of this Section 3, but (unless otherwise required by law) shall no longer be entitled to participation in the Company or other rights as a stockholder with respect to the Unvested Shares subject to the
repurchase. To the maximum extent permitted by law, Purchaser’s rights following the exercise of the Repurchase Option shall, with respect to the repurchase and the Unvested Shares covered thereby, be solely the rights that Purchaser has as a
general creditor of the Company to receive payment of the amount specified above in this Section 3. 
 21.
EXERCISE OF REPURCHASE OPTION. The Repurchase Option 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, 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. 

22. 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. 
 23. 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. 

  
 35. 

 24. 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. 
 25. 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. 
 26. 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. 
 27. 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.” 

  
 36. 

 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 ARE SUBJECT TO A RIGHT OF FIRST
REFUSAL OPTION IN FAVOR OF THE COMPANY AND/OR ITS ASSIGNEE(S) AS SET FORTH IN AN AGREEMENT WITH THE COMPANY, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.” 

d. “THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED PURSUANT TO THE EXERCISE OF [AN INCENTIVE STOCK OPTION/ A
NONSTATUTORY STOCK OPTION]. 
 e. Any legend required by appropriate blue sky officials. 

28. 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. 

  
 37. 

 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: (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. 
 g. Purchaser further warrants
and represents that Purchaser has either (i) preexisting personal or business relationships, with the Company or any of its officers, directors or controlling persons, or (ii) the capacity to protect his own interests in connection with
the purchase of the Common Stock by virtue of the business or financial expertise of Purchaser or of professional advisors to Purchaser who are unaffiliated with and who are not compensated by the Company or any of its affiliates, directly or
indirectly. Purchaser further warrants and represents that Purchaser’s purchase the Common Stock was not accomplished by the publication of any advertisement. 

29. 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. 
 30. 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 

  
 38. 

 
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 further understands that Purchaser must file an additional copy of
such 83(b) Election with his or her federal income tax return for the calendar year in which the date of this Agreement falls. 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. 
 31. 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. 

32. 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. 
 33. 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 

  
 39. 

 
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. 
 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 Cooley LLP, counsel to the Company and that Cooley 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. 

  
 40. 

 IN WITNESS WHEREOF, the parties hereto
have executed this Agreement as of                             .

Cooley LLP 
 3175 Hanover Street 

Palo Alto, California 94304 
 Dear Sir or Madam: 

As Escrow Agent for both Personalis, Inc., a Delaware corporation (“Company”), and the undersigned purchaser of Common Stock of the
Company (“Purchaser”), you are hereby authorized and directed to hold the documents delivered to you pursuant to the terms of that certain Early Exercise Stock Purchase Agreement (“Agreement”), dated
                             to which a copy of these Joint Escrow Instructions is attached as
Exhibit C, in accordance with the following instructions: 
 1. In the event the Company or an assignee shall elect to exercise
the Repurchase Option set forth in the Agreement, the Company or its assignee will give to Purchaser and you a written notice specifying the number of shares of Common Stock to be purchased, the purchase price, and the time for a closing hereunder
at the principal office of the Company. Purchaser and the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in accordance with the terms of said notice.

3. Purchaser irrevocably authorizes the Company to deposit with you any certificates evidencing shares of Common Stock to be held by you
hereunder and any additions and substitutions to said shares as specified in the Agreement. Purchaser does hereby irrevocably constitute and appoint you as the Purchaser’s

principal and interest due and payable under the promissory note attached to the Agreement, if any. 
 5. If at the time of
termination of this escrow you should have in your possession any documents, securities, or other property belonging to Purchaser, you shall deliver all of same to Purchaser and shall be discharged of all further obligations hereunder; provided,
however, that if at the time of termination of this escrow you are advised by the Company that the property subject to this escrow is the subject of a pledge or other security agreement, you shall deliver all such property to the pledgeholder or
other person designated by the Company. 

  
 42. 

 6. Except as otherwise provided in these Joint Escrow Instructions, your duties

such good faith. 
 8. You are hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by
any other person or corporation, excepting only orders or process of courts of law, and are hereby expressly authorized to comply with and obey orders, judgments or decrees of any court. In case you obey or comply with any such order, judgment or
decree of any court, you shall not be liable to any of the parties hereto or to any other person, firm or corporation by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled,
set aside, vacated or found to have been entered without jurisdiction. 
 9. You shall not be liable in any respect on account of the
identity, authority or rights of the parties executing or delivering or purporting to execute or deliver the Agreement or any documents or papers deposited or called for hereunder. 

10. You shall not be liable for the outlawing of any rights under any statute of limitations with respect to these Joint Escrow
Instructions or any documents deposited with you. 
 11. Your responsibilities as Escrow Agent hereunder shall terminate if you shall
cease to be the Company’s legal counsel or if you shall resign by written notice to the Company. In the event of any such termination, the Secretary of the Company shall automatically become the successor Escrow Agent unless the Company shall
appoint another successor Escrow Agent, and Purchaser hereby confirms the appointment of such successor as Purchaser’s attorney-in-fact and agent to the full extent
of your appointment. 
 12. If you reasonably require other or further instruments in connection with these Joint Escrow Instructions
or obligations in respect hereto, the necessary parties hereto shall join in furnishing such instruments. 
 13. It is understood and

 ACKNOWLEDGMENT AND STATEMENT OF DECISION 

REGARDING SECTION 83(b) ELECTION 

The undersigned has entered a stock purchase agreement with Personalis, Inc., a Delaware corporation (the “Company”), pursuant
to which the undersigned is purchasing                  shares of Common Stock of the Company (the “Shares”). In connection with the purchase of
the Shares, the undersigned hereby represents as follows: 
 1.    The undersigned has carefully reviewed the stock
purchase agreement pursuant to which the undersigned is purchasing the Shares. 
 2.    The undersigned either [check
and complete as applicable]: 
  

			
	        (a)        	 	has consulted, and has been fully advised by, the undersigned’s own tax advisor,
                                         
       , whose business address is
                                         
       , regarding the federal, state and local tax consequences of purchasing the Shares, and particularly regarding the advisability of making elections pursuant to Section 83(b) of the Internal Revenue
Code of 1986, as amended (the “Code”) and pursuant to the corresponding provisions, if any, of applicable state law; or
		
	        (b)        	 	has knowingly chosen not to consult such a tax advisor.

 3.    The undersigned hereby states that the undersigned has decided [check as
applicable]: 
  

			
	        (a)        	 	to make an election pursuant to Section 83(b) of the Code, and is submitting to the Company, together with the undersigned’s executed Common Stock Purchase Agreement, an executed form entitled “Election Under
Section 83(b) of the Internal Revenue Code of 1986;” or
		
	        (b)        	 	not to make an election pursuant to Section 83(b) of the Code.

 4.    Neither the Company nor any subsidiary or representative of the Company has made any

Menlo Park, California 94025 

THIS LEASE, referred to herein as this “Lease,” is made and entered into as of February 2, 2015, by and between MENLO
PREHC I, LLC, a Delaware limited liability company, MENLO PREPI I, LLC, a Delaware limited liability company, and TPI Investors 9, LLC, a California limited liability company, hereafter collectively referred to as “Lessor,” and
PERSONALIS, INC., a Delaware corporation, hereafter referred to as “Lessee” or “Personalis.” 

RECITALS: 
 A. Lessor is
the owner of the real property located in Menlo Business Park, Menlo Park, California, commonly referred to as 1330 O’Brien Drive and 1360 O’Brien Drive, more particularly described on Exhibit
“A-1” and Exhibit “A-2”, respectively, and attached hereto and incorporated by reference herein, together with all easements and
appurtenances thereto (collectively, the “Land”) and the existing buildings thereon, referred to as Building #5, containing approximately 25,366 rentable square feet with respect to 1330 O’Brien Drive and Building #6,
containing approximately 20,624 rentable square feet with respect to 1360 O’Brien Drive, and all other improvements located thereon (collectively, the “Improvements”). The Land and Improvements are referred to herein
collectively as the “Property.” The Menlo Business Park Master Plan is attached hereto as Exhibit “B” and incorporated by reference herein, and identifies the properties that comprise the Menlo Business Park.
Building #5 and Building #6 are collectively and individually referred to herein as the “Building.” The floor plan of Building #5 is attached hereto as Exhibit “C-1” and the floor
plan of Building #6 is attached hereto as Exhibit “C-2” and both exhibits are incorporated by reference herein. 

B. Lessor and Lessee wish to enter into this Lease of the Premises defined in Paragraph 1 upon the terms and conditions set forth herein. 

NOW, THEREFORE, the parties agree as follows: 

1. Lease. Lessor hereby leases to Lessee, and Lessee leases from Lessor, at the rental rate and upon the terms and conditions set forth
herein, the Premises (as hereinafter defined). Beginning on the Commencement Date (as defined in Paragraph 2(a)), Lessor hereby leases to Lessee, and Lessee leases from Lessor, (a) all of Building 5 consisting of approximately Twenty Five
Thousand Three Hundred Sixty Six (25,366) rentable square feet, as shown on the floor plan of Building 5 attached hereto as Exhibit “C-1” (the “Building 5 Premises”) and
(b) the second floor portion of Building 6 consisting of approximately Five Thousand Nine Hundred Fourteen (5,914) rentable square feet, as shown on the floor plan of Building 6 attached hereto as Exhibit
“C-2” (the “Building 6 Premises” and, collectively with the Building 5 Premises, referred to as the “Premises”), together with the right to use Lessee’s
share of the on-site parking spaces pursuant to Paragraph 28, and the non-exclusive right to use the common areas of the Building and the other Improvements on the
Property intended for use in common by the tenants of the Building. Lessee’s Pro Rata Share of Building 5 shall mean 100% (25,366/25,366) and Lessee’s Pro Rata Share of Building 6 shall mean 28.68% (5,914/20,624). 

  
 1. 

 2. Term. 

(a) The term of this Lease (the “Term”) shall commence on the later of (i) the date that Lessor delivers the Premises to
Lessee with the Tenant Improvements summarized on Exhibit “F” attached hereto Substantially Completed (the “Commencement Date”) and (ii) March 1, 2015. Upon the Commencement Date, the Building and all of
the systems of the Building, shall be in good operating condition and repair, including the roof and HVAC, mechanical, electrical, life safety and plumbing systems, and Landlord shall have labeled all electrical outlets and their corresponding
electrical panels. If the Premises should be found to not be in compliance with this Section 2 of this Lease on the Commencement Date or within the first ninety (90) days of the Term, provided Lessee provides Lessor
with written notice of the need for repair with a reasonable description thereof on or before the expiration of the ninetieth (90th) day following the Commencement Date, Lessor agrees to remedy such
non-compliance, at its sole cost and expense (and not as a charge to or Operating Expense payable by Lessee) within a reasonable amount of time following its receipt of Lessee’s notice hereunder. The
Commencement Date shall be confirmed in writing by Lessor and Lessee by the execution and delivery of the Commencement Memorandum in the form attached hereto as “Exhibit “D.” 

(b) The Term of this Lease shall expire, unless sooner terminated in accordance with the provisions hereof or as permitted by law, on the last
day of the sixty-sixth (66th) full calendar month after the Commencement Date. 
 (c) Lessee acknowledges that the applicable ordinance of
the City of Menlo Park (the “City”) requires that Lessee must obtain a Conditional Use Permit (“CUP”) from the City if Lessee maintains on the Premises five (5) gallons or more of Hazardous Materials (as
defined in Paragraph 9). Accordingly, for the period from the Commencement Date until the date Lessee obtains the CUP from the City permitting Lessee to maintain on the Premises five (5) gallons or more of Hazardous Materials (estimated to be
approximately seventy-five (75) days), Lessee shall maintain less than five (5) gallons of Hazardous Materials on the Premises. Lessee shall promptly apply for and shall use its commercially reasonable good faith diligent efforts to comply
with the City’s requirements for the issuance to Lessee of the CUP. Lessor shall assist Lessee in the filing and processing of the application for the CUP, and Lessee shall pay all costs associated with such efforts, including but not limited
to the costs and fees incurred by Green Environment and DES Architects/Engineers as well as City fees associated with the CUP; provided, however, Lessor shall not be responsible for the issuance of the CUP. Lessee shall deliver a copy of the CUP to
Lessor and Lessee shall comply with the provisions thereof. 
 3. Option to Extend. 

(a) Lessor hereby grants to Lessee one (1) option to extend the term of this Lease (the “Option to Extend”) for a period
of three (3) years (the “Extended Term”) immediately following the expiration of the Term. Lessee may exercise the Option to Extend by giving written notice of exercise to Lessor at least nine (9) months but no more than
twelve (12) months prior to the expiration of the initial Term of this Lease (“the Option Exercise 

  
 -2- 

 
Period”), time being of the essence; provided that if Lessee is in a state of uncured default after the expiration of all applicable notice and cure periods under this Lease at either
the time of the exercise of the Option to Extend or on the commencement date of the Extended Term, such notice shall be void and of no force or effect. The Extended Term, if the Option to Extend is exercised, shall be upon the same terms and
conditions as the initial Term of this Lease, including the payment by Lessee of the Additional Rent pursuant to Paragraph 5, except that (1) Lessee shall pay Monthly Base Rent, as determined as set forth in this Paragraph 3, during the
Extended Term, (2) there shall be no additional option to extend, and (3) Lessee shall accept the Premises in their then “as is” condition. If Lessee does not exercise the Option to Extend in a timely manner the Option to Extend
shall lapse, time being of the essence. 
 (b) The Option to Extend granted to Lessee by this Paragraph 3 is granted for the personal benefit
of Personalis, Inc. and any assignee of a Permitted Transfer (defined in Section 17 below) only, and shall be exercisable only by Personalis, Inc. or an assignee of a Permitted Transfer. The Option to Extend may not be assigned or transferred
to any other assignee or sublessee. 
 (c) The Monthly Base Rent for the Premises during the Extended Term shall be determined pursuant to
the provisions of this Paragraph 3(c) and shall equal the then current fair market rental for the Premises on the commencement date of the Extended Term as determined by agreement between the Lessor and Lessee reached prior to the expiration of the
Option Exercise Period, if possible, and by the process of appraisal if the parties cannot reach agreement. 
 (d) Upon the written request
by Lessee to Lessor received by Lessor at any time during the thirty (30) day period prior to the expiration of the Option Exercise Period and prior to the exercise by Lessee of the Option to Extend, Lessor shall give Lessee written notice of
Lessor’s good faith opinion of the amount equal to the fair market rental value of the Premises for the Extended Term. Thereafter, upon the request of Lessee, Lessor and Lessee shall enter into good faith negotiations during the remainder of
the thirty (30) days prior to the expiration of the Option Exercise Period in an effort to reach agreement on the initial Monthly Base Rent for the Premises during the Extended Term. 

If Lessor and Lessee are unable to agree upon the amount equal to the fair market rental value of the Premises for the Extended Term, and
thereafter, prior to the expiration of the Option Exercise Period, Lessee exercises the Option to Extend, said amount shall be determined by appraisal. The appraisal shall be performed by one appraiser if the parties are able to agree upon one
appraiser. If the parties are unable to agree upon one appraiser, then each party shall appoint an appraiser and the two appraisers shall select a third appraiser. Each appraiser selected shall be a member of the American Institute of Real Estate
Appraisers (AIREA) with at least five (5) years of full-time commercial real estate appraisal experience in the Menlo Park office/R&D/manufacturing rental market. 

If only one appraiser is selected, that appraiser shall notify the parties in simple letter form of its determination of the amount equal to
the fair market Monthly Base Rent for the Premises on the commencement date of the Extended Term within fifteen (15) days following its selection. Said appraisal shall be binding on the parties as the appraised current “fair market 

  
 -3- 

 
rental” for the Premises which shall be based upon what a willing new lessee would pay and a willing lessor would accept at arm’s length for comparable premises in the Menlo Park market
of similar age, size, quality of construction and specifications (excluding the value of any improvements to the Premises made at Lessee’s cost with Lessor’s prior written consent except as otherwise permitted herein) for a lease similar
to this Lease and taking into consideration that there will be no free rent, improvement allowance, or other rent concessions. If multiple appraisers are selected, the parties shall deliver their respective opinions of current fair market rental for
the Premises to each appraiser, and each appraiser shall within ten (10) days of being selected make its determination of which of the opinions, Lessor’s or Lessee’s, such appraiser has selected as the amount equal to the fair market
Monthly Base Rent for the Premises on the commencement date of the Extended Term in simple letter form. If two (2) or more of the appraisers agree on said amount, such agreement shall be binding upon the parties. If multiple appraisers are
selected and two (2) appraisers are unable to agree on said amount, the amount equal to the fair market Monthly Base Rent for the Premises on the commencement date of the Extended Term shall be determined by taking the mean average of the
opinions of fair market rent for the Premises, provided, that any high or low appraisal, differing from the middle appraisal by more than ten percent (10%) of the middle appraisal, shall be disregarded in calculating the average. 

If only one appraiser is selected, then each party shall pay one-half of the fees and expenses of that
appraiser. If three appraisers are selected, each party shall bear the fees of the appraiser it selects and one-half of the fees and expenses of the third appraiser. 

(e) Thereafter, provided that Lessee has previously given timely notice to Lessor of the exercise by Lessee of the Option to Extend, Lessor and
Lessee shall execute an amendment to this Lease stating that the initial Monthly Base Rent for the Premises during the Extended Term shall be equal to the determination by appraisal. 

4. Monthly Base Rent; Required Deposits upon Execution of Lease. 

(a) Commencing on the Commencement Date and continuing on the first day of each calendar month thereafter until the end of the Term, Lessee
shall pay to Lessor in monthly installments in advance the Monthly Base Rent for the Premises in lawful money of the United States as follows:

 (b) Upon the execution and delivery of this Lease by Lessee, Lessee shall pay to Lessor
(1) the cash sum of Sixty-Five Thousand Two Hundred and 00/100 Dollars ($65,250.00) representing the installment of Monthly Base Rent for the first full month in which Monthly Base Rent is due following the Commencement Date. Thereafter,
Monthly Base Rent shall be paid monthly in advance on the first day of each calendar month. Lessee shall also pay to Lessor upon execution and delivery of this Lease, the amount of Forty Nine Thousand Two Hundred Fifty and 00/100 Dollars
($49,250.00), which amount shall be applied to the Additional Rent (as hereinafter defined) for the first calendar month of the Term. Lessee shall also pay to Lessor upon the execution and delivery of this Lease the additional amount of Two Hundred
Forty Four Thousand Nine Hundred Twenty Two and 40/100 Dollars ($244,922.40) representing the Security Deposit (as defined in Paragraph 7 below). 

5. Additional Rent; Operating Expenses and Taxes. 

(a) In addition to the Monthly Base Rent payable by Lessee pursuant to Paragraph 4, commencing on the Commencement Date Lessee shall pay to
Lessor, as “Additional Rent,” (1) Lessee’s Pro Rata Share of the Operating Expenses of the Property, (2) Lessee’s pro rata share of the operating expenses for the Menlo Business Park of which the Property is a part (the
“Park Expenses”), and (3) Lessee’s Pro Rata Share of the Taxes (as defined in Paragraph 5(c) below). Lessee’s pro rata share of the operating expenses of Menlo Business Park is 3.56% based upon the ratio of the number
of square feet of the Land allocable to the Property to the total number of square feet of land in Menlo Business Park, as shown on Exhibit “B.” Lessee’s pro rata share of the Operating Expenses for 1330 O’Brien Drive
(Building #5) is 100% (25,366/25,366) and for 1360 O’Brien Drive (Building #6) is 28.68% (5,914/20,624). The Park Expenses, of which the Property is a part, currently include maintenance of the common areas of Menlo Business Park, parking lot
lighting (cost of electricity and maintenance of the fixtures), maintenance of the network conduit, all landscape maintenance and irrigation of Menlo Business Park, Lessor’s insurance coverages of Menlo Business Park, and security patrol. The
Park Expenses may include other commercially reasonable and customary items from time to time during the term of this Lease. Monthly Base Rent and Additional Rent are referred to herein collectively as “rent.” 

(b) “Operating Expenses,” as used herein, shall include all commercially reasonable and customary direct costs actually
incurred by Lessor in the management, operation, maintenance, repair and replacement of the Property, including the cost of all maintenance, repairs, and restoration of the Property performed by Lessor pursuant to Paragraphs 14(b) and 14(c) hereof,
as determined by generally accepted accounting principles (unless excluded by this Lease), including, but not limited to: 
 Personal
property taxes related to the Premises; any parking taxes or parking levies imposed on the Premises in the future by any governmental agency; a management fee charged for the management and operation of Menlo Business Park, in an amount equal to
four percent (4%) of the total gross income received by Lessor from the Lessee (including Monthly Base Rent 

  
 -5- 

 
and Additional Rent), and not just Lessee’s Pro Rata Share of this fee; water and sewer charges; waste disposal; insurance premiums for insurance coverages maintained by Lessor pursuant to
Paragraph 11(b) hereof; license, permit, and inspection fees; charges for electricity, heating, air conditioning, gas, and any other utilities (including, without limitation, any temporary or permanent utility surcharge or other exaction); security;
maintenance, repair, and replacement of the roof membrane (which if such replacement is a capital expenditure as determined in accordance with generally accepted accounting principles shall be subject to amortization as more fully described below);
painting and repairing, interior and exterior; maintenance and replacement of floor and window coverings (which if such replacements are capital expenditures as determined in accordance with generally accepted accounting principles shall be subject
to amortization as more fully described below); repair, maintenance, and replacement (which if such replacement is a capital expenditure as determined in accordance with generally accepted accounting principles shall be subject to amortization as
more fully described below) of air-conditioning, heating, mechanical and electrical systems, elevators, plumbing and sewage systems; janitorial service; landscaping, gardening, and tree trimming; glazing;
repair, maintenance, cleaning, sweeping, striping, and resurfacing of the parking area; exterior Building lighting and parking lot lighting; supplies, materials, equipment and tools in the maintenance of the Property; costs for accounting services

Commencement Date, or for any items or capital expenditures voluntarily made by Lessor which are intended to reduce Operating Expenses; provided, however, that except for capital improvements required because of Lessee’s specific use of the
Property, if Lessor is required to or voluntarily makes such capital improvements, Lessor shall amortize the cost of said improvements over the useful life of said improvements calculated in accordance with generally accepted accounting principles
(together with interest on the unamortized balance at the rate equal to the prime rate of interest as published in the “Wall Street Journal,” plus two percent (2%)) as an Operating Expense in accordance with generally accepted accounting
principles, except that with respect to capital improvements made to save Operating Expenses such amortization shall not be at a rate greater than the actual savings in Operating Expenses. Operating Expenses shall also include any other expense or
charge, whether or not described herein not specifically excluded by other provisions of this Lease, which in accordance with generally accepted accounting principles would be considered an expense of managing, operating, maintaining, and repairing
the Property. 
 (c) Real property taxes and assessments upon the Property, during each lease year or partial lease year during the term of
this Lease are referred to herein as “Taxes.” 
 As used herein, “Taxes” shall mean: 

(1) all real estate taxes, assessments, charges and any other taxes which are levied or assessed against the Property including the Land, the
Building, and all improvements located thereon, including any increase in Taxes resulting from a reassessment following any transfer of ownership of the Property or any interest therein or following any improvements to the Property, or improvements
to Menlo Business Park which are for the benefit of all occupants of Menlo Business Park; and 

  
 -6- 

 (2) all other taxes which may be levied in lieu of real estate taxes, assessments, and
other fees, charges, and levies, general and special, ordinary and extraordinary, unforeseen as well as foreseen, of any kind and nature by any authority having the direct or indirect power to tax, including without limitation any governmental
authority or any improvement or other district or division thereof, for public improvements, services, or benefits which are assessed, levied, confirmed, imposed, or become a lien (1) upon the Property, and/or any legal or equitable interest of
Lessor in any part thereof; or (2) upon this transaction or any document to which Lessee is a party creating or transferring any interest in the Property; and (3) any tax or excise, however described, imposed in addition to, or in
substitution partially or totally of, any tax previously included within the definition of “Taxes” or any tax the nature of which was previously included in the definition “Taxes.” 

Not included within the definition of “Taxes” are any net income, profits, transfer, franchise, estate, gift, rental income, or
inheritance taxes imposed by any governmental authority. “Taxes” also shall not include penalties or interest charges assessed on delinquent Taxes so long as Lessee is not in default in the payment of Monthly Base Rent or Additional Rent.

 With respect to any assessments which may be levied against or upon the Property, which under the laws then in force may be evidenced by
improvement or other bonds, or may be paid in annual installments, only the amount of such annual installment (with appropriate proration of any partial year) and statutory interest shall be included within the computation of the annual Taxes levied
against the Property.

Business Park and Costs arising from the violation by Lessor or any other occupant of the Menlo Business Park of the terms and conditions of any lease or other agreement; 

(13) Costs incurred in connection with the presence of any Hazardous Materials on the Property or on other property in Menlo Business Park
that were not caused by or the result of a release by Lessee or its employees, agents, contractors, invitees, sublessees, successors or assigns; and 

(14) Expense reserves; and 

(15) Capital costs, except to the extent permitted in Paragraph 5(b) above. 

Lessor shall at all times use its best efforts to operate the Property in an economically reasonable manner at costs not disproportionately
higher than those experienced by other comparable premises in the market area in which the Property is located. 
 (e) Prior to the execution
of this Lease, Lessor has delivered to Lessee Lessor’s estimate of 2014 Operating Expenses, Taxes and Park Expenses. Throughout the term of this Lease, as close as reasonably possible after the end of each calendar year thereafter but no later
than April 1 of the following year, Lessor shall notify Lessee of the Operating Expenses, Taxes and Park Expenses estimated by Lessor for the calendar year 2015, and for each following calendar year. Concurrently with such notice, Lessor shall
provide a description of such Operating Expenses, Taxes and Park Expenses. Commencing on the Commencement Date, and on the first (1st) day of each calendar month thereafter, Lessee shall pay to Lessor, as Additional Rent, one-twelfth (1/12th) of Lessee’s Pro Rata Share of the estimated Operating Expenses, Taxes and Park Expenses. If at any time during any such calendar year, it appears to Lessor that the Operating Expenses,
Taxes or Park Expenses for such year will vary from Lessor’s estimate, Lessor may, by written notice to Lessee, revise Lessor’s estimate for such 

  
 -8- 

 
year and the Additional Rent payments by Lessee for such year shall thereafter be based upon such revised estimate. Lessor shall furnish to Lessee with such revised estimate written verification
showing that the actual Operating Expenses, Taxes or Park Expenses are greater than or equal to Lessor’s estimate. The increase in the monthly installments of Additional Rent resulting from Lessor’s revised estimate shall not be
retroactive, but the Additional Rent for each calendar year shall be subject to adjustment between Lessor and Lessee after the close of the calendar year, as provided below. 

Within approximately ninety (90) days after the expiration of each calendar year of the term, Lessor shall furnish Lessee a statement
certified by a responsible employee or agent of Lessor (the “Operating Statement”) with respect to such year, prepared by an employee or agent of Lessor, showing the actual Operating Expenses, Taxes and Park Expenses for such year
broken down by component expenses, and the total payments made by Lessee for such year on the basis of any previous estimate of such Operating Expenses, Taxes and Park Expenses, all in sufficient detail for verification by Lessee. Unless Lessee
raises any objections to the Operating Statement within ninety (90) days after receipt of the same, such statement shall conclusively be deemed correct and Lessee shall have no right thereafter to dispute such statement or any item therein or
the computation of Operating Expenses and/or Taxes and/or Park Expenses. Upon giving Lessor five (5) days advance written notice, Lessee or its accountants shall have the right to inspect and audit Lessor’s books and records with respect
to the Operating Statement in an office of Lessor, or Lessor’s agent, located in Menlo Park, California, during normal business hours, once each Lease Year to verify actual Operating Expenses and/or Taxes and/or Park Expenses. Should Lessee
retain any accountant or accounting firm to audit or inspect Lessor’s books and records pursuant to this Paragraph 5(e), such accountant or accounting firm shall be one of national standing and retained on an hourly rate basis or based upon a
fixed fee and shall not be paid on a contingency basis. Lessor’s books and records shall be kept in accord with generally accepted accounting principles. If Lessee’s audit of the Operating Expenses and/or Taxes and/or Park Expenses for any
year reveals a net overcharge of more than five percent (5%), Lessor shall promptly reimburse Lessee for the cost of the audit; otherwise, Lessee shall bear the cost of Lessee’s audit. If Lessee reasonably objects to Lessor’s Operating
Statement, Lessee shall nonetheless continue to pay on a monthly basis the Operating Expenses, Taxes and Park Expenses based upon the Lessor’s most current estimate until such dispute is resolved. 

If Lessee’s Pro Rata Share of the Operating Expenses and Taxes and Lessee’s pro rata share of Park Expenses for any year as finally
determined exceed the total payments made by Lessee for such year based on Lessor’s estimates, Lessee shall pay to Lessor the deficiency, within thirty (30) days after the receipt of Lessor’s Operating Statement. If the total payments
made by Lessee based on Lessor’s estimate of the Operating Expenses and/or Taxes and/or Park Expenses exceed the Lessee’s Pro Rata Share of Operating Expenses and/or Taxes and/or Lessee’s pro rata share of Park Expenses, Lessee’s
extra payment, plus the cost of an audit which is the responsibility of Lessor as set forth herein, if any, shall be credited against payments of Monthly Base Rent and Additional Rent next due hereunder or returned within thirty (30) days if
the term has expired or this Lease has been terminated. 

  
 -9- 

 Notwithstanding the expiration or termination of this Lease, within thirty (30) days
after Lessee’s receipt of Lessor’s Operating Statement or the completion of Lessee’s audit regarding the Operating Expenses and/or Taxes and/or Park Expenses for the calendar year in which this 

Lease terminates, Lessee shall pay to Lessor or shall receive from Lessor, as the case may be, an amount equal to the difference between the Operating Expenses
and/or Taxes and/or Park Expenses for such year, as finally determined (which final determination Lessor shall endeavor to complete within six (6) months following the end of the Term), and the amount previously paid by Lessee on account
thereof (prorated to the expiration date or the termination date of this Lease). 
 6. Payment of Rent. 

(a) All rent shall be due and payable in lawful money of the United States of America at the address of Lessor set forth in Paragraph 24,
“Notices,” without deduction or offset and without prior demand or notice, unless otherwise specified herein. Monthly Base Rent and Additional Rent due under this Lease shall be payable monthly, in advance, on the first day of each month.
Additional Rent shall be payable monthly, in advance, on the first day of each month for the entire Premises for the entire term of his Lease. Lessee’s obligation to pay rent for any partial month at the commencement of the Term, for any
partial month immediately prior to a rental adjustment date (if the rental adjustment date is other than the first day of the calendar month), and for any partial month at the expiration or termination of the Term shall be based upon the number of
days in such month. 
 (b) If any installment of Monthly Base Rent, Additional Rent or any other sum due from Lessee is not received by
Lessor within five (5) days after the same is due, Lessee shall pay to Lessor an additional sum equal to five percent (5%) of the amount overdue as a late charge. The parties agree that this late charge represents a fair and reasonable estimate
of the costs that Lessor will incur by reason of the late payment by Lessee. Acceptance of any late charge shall not constitute a waiver of Lessee’s default with respect to the overdue amount. Any amount not paid within ten (10) days after
Lessee’s receipt of written notice that such amount is due shall bear interest from the date due until paid at the lesser rate of (1) the prime rate of interest as published in the “Wall Street Journal,” plus two percent (2%) or
(2) the maximum rate allowed by law (the “Interest Rate”), in addition to the late payment charge.

 7. Security Deposit. Lessee shall deposit with Lessor upon execution hereof the sum of Two Hundred Forty
Four Thousand Nine Hundred Twenty Two and 40/100 Dollars ($244,922.40) (the “Security Deposit”), as security for Lessee’s faithful performance of Lessee’s obligations under this Lease. If Lessee fails to pay Monthly Base Rent or
Additional Rent or charges due hereunder within applicable notice and cure periods, or otherwise defaults under this Lease (as defined in Paragraph 22), Lessor may use, apply or retain all or any portion of said Security Deposit to the extent
reasonably necessary to cure the default, for the payment of any amount due Lessor, and to reimburse or compensate Lessor for any liability, cost, expense, loss or damage (including attorneys’ fees) which Lessor may suffer or incur by reason
thereof. If Lessor uses or applies all or any portion of the Security Deposit, Lessee shall within ten (10) days after written request therefor deposit with Lessor the amount sufficient to restore the Security Deposit to the original amount
required by this Lease. Lessor shall not be required to keep all or any part of the Security Deposit separate from its general accounts. In no event or circumstance shall Lessee have the right to any use of the Security Deposit and, specifically,

  
 -10- 

 
Lessee may not use the Security Deposit as a credit or to otherwise offset any payments required hereunder, including, but not limited to, rent or any portion thereof. Lessee waives
(i) California Civil Code Section 1950.7 and any and all other laws, rules and regulations applicable to security deposits in the commercial context (“Security Deposit Laws”), and (ii) any and all rights, duties and
obligations either party may now has, or in the future will have, relating to or arising from the Security Deposit Laws. Notwithstanding anything to the contrary herein, the Security Deposit may be retained and applied by Lessor (a) to offset
rent which is unpaid either before or after termination of this Lease, and (b) against other damages suffered by Lessor before or after termination of this Lease. No part of the Security Deposit shall be considered to be held in trust, to bear
interest or other increment for its use, or to be prepayment for any moneys to be paid by Lessee under this Lease. 
 8. Use. Lessee
may only use and occupy the Premises for general office uses, administrative purposes, research and development, laboratory and related legal uses which are permitted by applicable zoning ordinances and the covenants, conditions, and restrictions
for Menlo Business Park and which are approved by Lessor in writing, and for no other use or purpose without Lessor’s prior written consent; provided, that the use of the Premises for the manufacture of integrated circuits is expressly
prohibited. Any use of the Premises by Lessee or by any sublessee or assignee approved by Lessor pursuant to Paragraph 17 shall comply with the provisions of this Paragraph 8. 

9. Hazardous Materials. 

(a) The term “Hazardous Materials” as used in this Lease shall include any substance defined or regulated as radioactive, flammable,
toxic, a biohazard, medical waste, “hazardous material”, “extremely hazardous material”, “hazardous waste”, “hazardous substance,” “toxic substance,” “industrial process waste,” or
“special waste” in any Environmental Laws as hereafter defined. Hazardous Materials shall include, but not be limited to, petroleum, gasoline, natural gas, natural gas liquids, liquefied natural gas, synthetic gas, and/or crude oil or any
products, by-products or fractions thereof. 
 (b) Lessee shall not engage in any activity in or on
the Premises or the Property which constitutes a Reportable Use of Hazardous Materials without the express prior written consent of Lessor and timely compliance (at Lessee’s expense) with all Environmental Laws. “Reportable
Use” shall mean (i) the installation or use of any above or below ground storage tank, (ii) the generation, possession, storage, use, transportation, or disposal of Hazardous Materials that require a permit from, or with respect
to which a report, notice, registration or business plan is required to be filed with, any governmental authority, and/or (iii) the presence at the Premises or the Property of Hazardous Materials with respect to which any Environmental Law
requires that a notice be given to persons entering or occupying the Premises, or the Property, or neighboring properties. Notwithstanding the foregoing, subject to the provision of Paragraph 2(d) (including the requirement that Lessee shall obtain
a Conditional Use Permit from the City before Lessee maintains on the Premises five (5) gallons or more of any Hazardous Materials) Lessee may use the Hazardous Materials on the Premises that are listed on Exhibit “E” attached
hereto and incorporated by reference herein, and any ordinary and customary office supplies, cleaning materials, and other materials reasonably required to be used in the normal course of Lessee’s agreed use of the Premises, so long as such

  
 -11- 

 
use is in compliance with all Environmental Laws, and does not expose the Premises, or the Property, or neighboring property to any unusual or atypical risk of contamination or damage or expose
Lessor to any liability therefor. In addition, Lessor may condition its consent to any Reportable Use upon receiving such additional assurances as Lessor reasonably deems necessary to protect itself, the public, the Premises and the Property, and/or
the environment against damage, contamination, injury and/or liability, including, but not limited to, the installation (and removal on or before Lease expiration or termination) of any protective modifications installed by Lessee (such as concrete
encasements). 
 (c) “Environmental Laws” shall mean and include any Federal, State, or local statute, law, ordinance, code,
rule, regulation, order, or decree regulating, relating to, or imposing liability or standards of conduct concerning, any hazardous, toxic, or dangerous waste, substance, element, compound, mixture or material, as now or at any time hereafter in
effect including, without limitation, California Health and Safety Code §§25100 et seq., §§25300 et seq., Sections 25281(f) and 25501 of the California Health and Safety Code, Section 13050 of the Water Code, the Federal
Comprehensive Environmental Response, Compensation and Liability Act, as amended, 42 U.S.C. §§9601 et seq. (“CERCLA”), the Superfund Amendments and Reauthorization Act, 42 U.S.C. §§9601 et seq., the Federal Toxic
Substances Control Act, 15 U.S.C. §§2601 et seq., the Federal Resource Conservation and Recovery Act as amended, 42 U.S.C. §§6901 et seq., the Federal Hazardous Material Transportation Act, 49 U.S.C. §§1801 et seq., the
Federal Clean Air Act, 42 U.S.C. §7401 et seq., the Federal Water Pollution Control Act, 33 U.S.C. §1251 et seq., the River and Harbors Act of 1899, 33 U.S.C. §§401 et seq., and all rules and regulations of the EPA, the
California Environmental Protection Agency, or any other state or federal department, board or any other agency or governmental board or entity having jurisdiction over the environment, as any of the foregoing have been, or are hereafter amended.

 (d) If Lessee knows, or has reasonable cause to believe, that Hazardous Materials have come to be located in, on, under or about the
Premises or the Property, other than as previously consented to by Lessor, Lessee shall immediately give written notice of such fact to Lessor and provide Lessor with a copy of any report, notice, claim or other documentation which it has concerning
the presence of such Hazardous Materials. 
 (e) Lessee and Lessee’s agents, employees, and contractors shall not cause any Hazardous
Materials to be discharged or released into the Building or into the plumbing or sewage system of the Building or into or onto the Land underlying or adjacent to the Building in violation of any Environmental Laws. Lessee shall promptly, at
Lessee’s expense, take all investigatory and/or remedial action reasonably recommended, whether or not formally ordered or required, for the cleanup of any contamination in violation of Environmental Laws or the terms of this Lease caused by
Lessee or caused by any of Lessee’s employees, agents, or contractors, and for the maintenance, security and/or monitoring of the Premises, the Property, or neighboring properties if such contamination is caused by a release or emission of any
Hazardous Materials by Lessee or by any of Lessee’s employees, agents, or contractors. 

  
 -12- 

 (f) Lessee shall indemnify, defend and hold Lessor and its agents, employees, and lenders
and the Premises and the Property harmless from any and all claims, damages, fines, judgments, penalties, costs, liabilities or losses (including, without limitation, any and all sums paid for settlement of claims, attorneys’ fees, consultant
and expert fees) arising during or after the term of this Lease out of or involving any Hazardous Materials brought on to the Premises, the Property, or Menlo Business Park by or for Lessee or by anyone under Lessee’s control in violation of
Environmental Laws or the terms of this Lease. Lessee’s obligations under this Paragraph 9(f) shall include, but not be limited to, the effects of any contamination or injury to person, property or the environment created or suffered by Lessee,
and the cost of investigation (including consultants’ and attorneys’ fees and testing), removal, remediation, restoration and/or abatement thereof, or of any contamination therein involved, as required by Environmental Laws, and shall
survive the expiration or earlier termination of this Lease. No termination, cancellation or release agreement entered into by Lessor and Lessee shall release Lessee from its obligations under this Lease with respect to Hazardous Materials, unless
specifically so agreed by Lessor in writing at the time of such agreement. 
 10. Taxes on Lessee’s Property. Lessee shall pay
before delinquency any and all taxes, assessments, license fees, and public charges levied, assessed, or imposed and which become payable during the Term and any extension thereof upon Lessee’s equipment, fixtures, furniture, and personal
property installed or located on the Premises. 
 11. Insurance. 

(a) Lessee shall, at Lessee’s sole cost and expense, provide and keep in force commencing with the Commencement Date of the Term and
continuing during the Term, a commercial general liability insurance policy with a recognized casualty insurance company qualified to do business in California, insuring against liability occasioned by any occurrence in, on, about, or related to the
Premises, or arising out of the condition, use, occupancy, alteration or maintenance of the Premises and covering the contractual liability referred to in Paragraph 12(a) of this Lease, having a combined single limit for both bodily injury and
property damage in an amount not less than Three Million Dollars ($3,000,000) per occurrence and annual aggregate. Limit requirements may be met through a combination of primary and excess liability policies. All such insurance carried by Lessee
shall be in a form reasonably satisfactory to Lessor and its mortgage lender and shall be carried with companies that have a general policyholder’s rating of not less than “A” and a financial rating of not less than Class
“X” in the most current edition of Best’s Insurance Reports; shall provide that such policies shall not be subject to reduction in types of coverage or limits below those required in Section 11(a) or cancellation except after at
least thirty (30) days’ prior written notice to Lessor (which notice may be provided by Lessee if Lessee’s carrier will not agree to provide such notice directly to Lessor); and shall be primary as to Lessor. Prior to the Commencement
Date and upon renewal of such policies not less than twenty (20) days prior to the expiration of the term of such coverage, Lessee shall deliver to Lessor certificates of insurance confirming such coverage, naming Lessor and Lessor’s
property manager, Tarlton Properties, Inc., as additional insureds. If Lessee fails to procure and maintain the insurance required hereunder, after three (3) business days’ notice to Lessee, Lessor may, but shall not be required to, order
such insurance at Lessee’s expense and Lessee shall reimburse Lessor for all costs incurred by Lessor with respect thereto. Lessee’s reimbursement to Lessor for such amounts shall be deemed Additional Rent, and shall include all sums
disbursed, incurred or deposited by Lessor, including Lessor’s costs, expenses and reasonable attorneys’ fees with interest thereon at the Interest Rate. 

  
 -13- 

 (b) Lessor shall obtain and carry in Lessor’s name, as insured, as an Operating Expense
of the Property to the extent provided in Paragraph 5(b), during the lease term, “all risk” property insurance coverage (with rental loss insurance coverage for a period of one year), flood insurance, public liability and property damage
insurance, and insurance against such other risks or casualties as Lessor shall reasonably determine, including, but not limited to, insurance coverages required of Lessor by the beneficiary of any deed of trust which encumbers the Property,
including earthquake insurance coverage insuring Lessor’s interest in the Property (including the Initial Tenant Improvements constructed in the Premises pursuant to Paragraph 13 and any other leasehold improvements to the Premises constructed
by Lessor or by Lessee with Lessor’s prior written approval) in an amount not less than the full replacement cost of the Building and all other Improvements from time to time; provided that the deductible amounts applicable to the coverages
maintained by Landlord shall not be materially greater than those typically carried by landlords of properties similar to the Premises and located in Menlo Park, California. The proceeds of any such insurance shall be payable solely to Lessor, and
Lessee shall have no right or interest therein. Lessor shall have no obligation to insure against loss by Lessee to Lessee’s equipment, fixtures, furniture, inventory, or other personal property of Lessee in or about the Premises occurring from
any cause whatsoever. 
 (c) Notwithstanding anything to the contrary contained in this Lease, the parties release each other, and their
respective authorized representatives, employees, officers, directors, shareholders, managers, members, trustees, beneficiaries, assignees, subtenants, invitees, successors, agents, contractors and property managers, from any claims for damage to
any person or to the Premises or the Property and to the fixtures, personal property, leasehold improvements and alterations of either Lessor or Lessee in or on the Premises or the Property, to the extent that are caused by or result from risks
required by this Lease to be insured against (or actually insured against) under any property insurance policies carried by the parties and such policy is in force at the time of any such damage, whichever is greater. This waiver applies whether or
not the loss is due to the negligent acts or omissions of Lessor or Lessee or their respective authorized representatives, employees, officers, directors, shareholders, managers, members, trustees, beneficiaries, assignees, subtenants, invitees,
successors, agents, contractors and property managers. Subject to the foregoing, this release and waiver shall be complete and total even if such loss or damage may have been caused by the negligence of the other party, its managers, members,
employees, agents, contractors, property managers or invitees. Lessee covenants that the insurance policies required to be maintained by Lessee under this Lease will contain waiver of subrogation endorsements. 

12. Indemnification. 
 (a)
Lessee shall indemnify, defend, and hold harmless Lessor from claims, suits, actions, or liabilities for personal injury, death or for loss or damage to property caused by or resulting from (1) any activity, work, or thing done or permitted by
Lessee in or about the Premises, the Property or the Park, (2) bodily injury or damage to property which arises in or about the Property to the extent the injury or damage to property is caused by the acts or omissions of Lessee, its employees,
agents or contractors, and (3) caused by or resulting from any event of default by Lessee in the performance of any obligation on Lessee’s part to be performed under this Lease. Lessee also waives all claims against Lessor and its
employees, agents and contractors for damages to property, or to goods, wares, and merchandise stored in, upon, or about the Premises or the Property, and for injuries to persons in, upon, or about the Premises or the Property from any cause arising
at any time, except to the extent caused by the active negligence or willful misconduct of Lessor or its employees, agents or contractors. 

  
 -14- 

 (b) Lessor shall indemnify, defend, and hold harmless Lessee from claims, suits, actions, or
liabilities for personal injury, death or for loss or damage to property caused by (1) any activity, work, or thing done by Lessor in or about the Premises or the Property, and (2) bodily injury or damage to property which arises in or about
the Property to the extent the injury or damage to property is caused by the active negligent acts of Lessor, its employees, agents or contractors. 

(c) In the absence of comparative or concurrent negligence on the part of Lessee or Lessor, their respective agents, affiliates, and
subsidiaries, or their respective officers, directors, members, employees or contractors, the foregoing indemnities by Lessee and Lessor shall also include reasonable costs, expenses and attorneys’ fees incurred in connection with any
indemnified claim or incurred by the indemnitee in successfully establishing the right to indemnity. The indemnitor shall have the right to assume the defense of any claim subject to the foregoing indemnities with counsel reasonably satisfactory to
the Indemnitee. The indemnitee agrees to cooperate fully with the indemnitor and its counsel in any matter where the indemnitor elects to defend, provided the indemnitor shall promptly reimburse the indemnitee for reasonable costs and expenses
incurred in connection with its duty to cooperate. 
 The foregoing indemnities shall survive the expiration or earlier termination of this
Lease and are conditioned upon the indemnitee providing prompt notice to the indemnitor of any claim or occurrence that is likely to give rise to a claim, suit, action or liability that will fall within the scope of the foregoing indemnities, along
with sufficient details that will enable the indemnitor to make a reasonable investigation of the claim. 
 When the claim is caused by the
joint negligence or willful misconduct of Lessee and Lessor or by the indemnitor party and a third party unrelated to the indemnitor party (except indemnitor’s agents, officers, employees or invitees), the indemnitor’s duty to indemnify
and defend shall be proportionate to the indemnitor’s allocable share of joint negligence or willful misconduct. 
 (d) Lessor shall not
be liable to Lessee for any damage because of any act or negligence of any other occupant of the Building or any other owner or occupant of adjoining or contiguous property, nor for overflow, breakage, or leakage of water, steam, gas, or electricity
from pipes, wires, or otherwise in the Premises or the Building, except to the extent caused by the gross negligence or willful misconduct of Lessor or Lessor’s employees, agents, or contractors. Except as otherwise provided herein, Lessee will
pay for damage to the Premises or the Property caused by the misuse or neglect of the Premises or the Property by Lessee or its employees, agents, or contractors, including, but not limited to, the breakage of glass in the Building. 

  
 -15- 

 13. Tenant Improvements. 

(a) Lessor, at its cost and expense, shall cause to be constructed the interior tenant improvements and modifications to the Premises described
on Exhibit F attached hereto (the “Tenant Improvements”). Lessor shall pay directly to the applicable design professional, contractor, materialman or other laborer costs in connection with the construction of the Tenant
Improvements. Lessee shall be liable for all fees and costs of the design and construction of the Tenant Improvements which are outside of the scope of work described on Exhibit F attached hereto (such amount referred to herein as the
“Tenant Improvement Shortfall”). Lessee shall pay the Tenant Improvement Shortfall upon written request from Lessor accompanied by invoices reflecting such amounts due within thirty (30) days following Lessor’s delivery of
such payment request. 
 (b) The terms “Substantially Complete,” “Substantially Completed” or
“Substantial Completion” shall mean the date the Tenant Improvements are completed in good and workmanlike manner in accordance with applicable laws, and the Premises are in the condition required by this Lease, excepting only minor
Punch List items (as defined below), which do not unreasonably interfere with Lessee’s ability to commence business operations at the Premises. 

(c) The Tenant Improvements shall be constructed in accordance with all applicable laws and the terms of this Lease, in a good and workmanlike
manner, free of defects and using new materials and equipment of good quality. Upon delivery of the Premises to Lessee, Lessor and Lessee shall coordinate a walk-through of the Premises and Lessor and Lessee shall complete a punch list indicating
any deficiencies in the Tenant Improvements (“Punch List”). Lessor shall as soon as reasonably practicable using diligence cause such items set forth in the Punch List to be completed as required for compliance with the Tenant
Improvements. 
 (d) Subject to completion of the Tenant Improvements, Lessee waives all right to make repairs at the expense of Lessor, or
to deduct the costs thereof from the rent, and Lessee waives all rights under Section 1941 and 1942 of the Civil Code of the State of California. At the expiration or sooner termination of this Lease, Lessee shall surrender the Premises in a
clean and good condition (including the Tenant Improvements upon completion thereof which Lessee shall not be required to remove) and in accordance with Paragraph 14, except for ordinary wear and tear, damage caused by casualty, and alterations or
other improvements made by Lessee with Lessor’s prior written consent which Lessee is not required to remove as a condition to Lessor’s approval of such alterations or improvements. 

14. Maintenance and Repairs; Alterations; Surrender and Restoration. 

(a) Lessor shall, at Lessor’s sole expense, keep in good order, condition, and repair and replace when necessary, the structural elements
of the roof (excluding the roof membrane which Lessor shall maintain, but the cost of which shall be included as an Operating Expense as permitted under Paragraph 5), and the structural elements of the foundation and exterior walls (except the
interior faces thereof) of the Building, and other structural elements of the Building and the Property as “structural elements” are defined in building codes applicable 

  
 -16- 

 
to the Building, excluding any alterations, structural or otherwise, made by Lessee to the Building which are not approved in writing by Lessor prior to the construction or installation thereof
by Lessee. Lessor shall perform and construct, and Lessee shall not be responsible for performing or constructing, any repairs, maintenance, or improvements (1) required as a result of any casualty damage (not caused by the willful or negligent
acts or omissions of Lessee or its employees, agents, contractors or invitees), which shall be subject to Paragraph 20 below, or as a result of any taking pursuant to the exercise of the power of eminent domain, or (2) for which Lessor has a
right of reimbursement from third parties based on construction or other warranties, contractor guarantees, or insurance claims. 
 (b)
Lessor shall provide or cause to be provided and shall supervise the performance of, as an Operating Expense of the Property as permitted under Paragraph 5(b) hereof, all services and work relating to the operation, maintenance, repair, and
replacement, as needed, of the Property, including the HVAC, mechanical, electrical, life safety (except that Lessee shall maintain any and all hand held fire extinguishers in the Premises) and plumbing systems in the Building; the interior of the
Building; the roof membrane; the outside areas of the Property; the janitorial service for the Building; landscaping, tree trimming, resurfacing and restriping of the parking lot, repairing and maintaining the walkways; exterior building painting,
exterior building lighting, parking lot lighting, and exterior security patrol. In the event Lessee provides Lessor with written notice of the need for any repairs, Lessor shall commence any such repairs promptly following receipt by Lessor of such
notice and Lessor shall diligently prosecute such repairs to completion. 
 (c) Subject to the foregoing and except as provided elsewhere in
this Lease, Lessee shall at all times use and occupy the Premises in a manner which keeps the Premises in good and safe order, condition, and repair. In addition to the foregoing, Lessee shall cause the carpets in the Premises to be professionally
cleaned at least two (2) times per calendar year during the Term. Lessor shall execute and maintain in full force and effect throughout the term as an Operating Expense of the Property pursuant to Paragraph 5(b) a service contract with a
recognized air conditioning service company. Lessor may, if Lessor determines that it is necessary to do so, obtain on a semi-annual basis an inspection report of the HVAC system from a separate HVAC service firm designated by Lessor for the purpose
of monitoring the performance of the HVAC maintenance and repair work performed by the HVAC service firm which performs the regular repair and maintenance. The cost of such inspection report shall be an Operating Expense pursuant to Paragraph 5.
Subject to the release of claims and waiver of subrogation contained in Paragraphs 11(c) and 11(d), if Lessor is required to make any repairs to the Property by reason of Lessee’s negligent acts or omissions, Lessor may add the cost of such
repairs to the next installment of rent which shall thereafter become due, and Lessee shall promptly pay the same upon receipt of an invoice therefor. 

(d) Lessee may, from time to time, at its own cost and expense and without the consent of Lessor make nonstructural alterations provided they
do not affect any of the Building systems (including the roof, plumbing, sewer, electrical, life safety, HVAC or other mechanical systems) to the interior of the Premises the cost of which in any one instance is Twenty-Five Thousand and 00/100
Dollars ($25,000.00) or less, and the aggregate cost of all such work during the Term this Lease does not exceed One Hundred Thousand and 00/100 Dollars ($100,000.00), provided Lessee first notifies Lessor in writing of any such nonstructural

  
 -17- 

 
alterations. Otherwise, Lessee shall not make any additional alterations, improvements, or additions to the Premises without delivering to Lessor a complete set of plans and specifications for
such work, obtaining and delivering copies to Lessor of all permits or other governmental approvals required for such work and obtaining Lessor’s prior written consent thereto. All alterations and additions shall be installed by a licensed
contractor approved by Lessor, at Lessee’s sole expense in compliance with all applicable laws, rules, regulations and ordinances. Lessee shall keep the Premises and the Property on which the Premises are situated free from any liens arising
out of any work performed, materials furnished or obligations incurred by or on behalf of Lessee. If any nonstructural alterations to the interior of the Premises (i) exceed Twenty-Five Thousand and no/100s Dollars ($25,000.00) in cost in any
one instance, (ii) exceed the aggregate cost of One Hundred Thousand and no/100s Dollars ($100,000.00) during the Term of this Lease, or (iii) affect any of the Building systems described above, Lessee shall employ, at Lessee’s
expense, Tarlton Properties, Inc. as construction manager for such alterations at a fee equal to five percent (5%) of the first Two Hundred Fifty Thousand Dollars ($250,000.00) of hard construction costs (i.e., the amounts paid to any general
contractor, subcontractors, vendors, and suppliers for labor and materials for the construction of the alterations or improvements) and then four percent (4%) of such hard construction costs in excess of Two Hundred Fifty Thousand Dollars
($250,000.00). Lessor may condition its consent to, among other things, Lessee agreeing in writing to remove any such alterations prior to the expiration of the Lease term and Lessee agreeing to restore the Premises to its condition prior to such
alterations at Lessee’s expense. Upon Lessee’s written request, Lessor shall advise Lessee in writing at the time consent is granted whether Lessor reserves the right to require Lessee to remove any alterations from the Premises prior to
the expiration or sooner termination of this Lease. 
 All alterations, trade fixtures and personal property installed in the Premises
solely at Lessee’s expense shall during the term of this Lease remain Lessee’s property and Lessee shall be entitled to all depreciation, amortization and other tax benefits with respect thereto. Upon the expiration or sooner termination
of this Lease all alterations, fixtures and improvements to the Premises, whether made by Lessor or installed by Lessee at Lessee’s expense, shall be surrendered by Lessee with the Premises and shall become the property of Lessor; provided,
however, that Lessee’s furniture and other personal property, not provided by or paid for by Lessor and not permanently affixed to the Premises which can be removed without damaging the Premises may be removed by Lessee. Lessee shall repair to
Lessor’s reasonable satisfaction all damage to the Premises occasioned by removal of Lessee’s Property. 
 (e) Lessee shall, at
Lessee’s sole cost and expense, comply with all present and future “Laws,” which term is used in this Lease to mean all laws, rules, regulations, ordinances, directives, orders, covenants, permits of all governmental agencies
and authorities, easements and restrictions of record, the requirements of any applicable fire insurance underwriter or rating bureau or board of fire underwriters, relating in any manner to the Premises and/or Lessee’s use or occupancy of the
Premises (including but not limited to matters pertaining to industrial hygiene, environmental conditions on, in, under or about the Premises, including soil and groundwater conditions, subject to the provisions of Paragraph 9 hereof, and the use,
generation, manufacture, production, installation, maintenance, removal, transportation, storage, spill, or release of any Hazardous Materials (which Hazardous Materials are addressed in Paragraph 9 hereof)), now in effect or which may hereafter
come into effect. Lessee shall, 

  
 -18- 

 
within five (5) days after receipt of Lessor’s written request, provide Lessor with copies of all documents and information, including but not limited to permits, registrations,
manifests, applications, reports and certificates, evidencing Lessee’s compliance with any Laws specified by Lessor, and shall immediately upon receipt, notify Lessor in writing (with copies of any documents involved) of any threatened or
actual claim, notice, citation, warning, complaint or report pertaining to or involving failure by Lessee or the Premises to comply with any Laws. Notwithstanding the foregoing, any structural changes or repairs or other changes or repairs to the
Property of any nature which would be considered a capital expenditure under generally accepted accounting principles to the Premises shall be made by Lessor at Lessee’s expense if such structural repairs or changes are required by reason of
the specific nature of the use of the Premises by Lessee. If such changes or repairs are not required by reason of the specific nature of Lessee’s use of the Premises and are capital expenditures, the cost of such changes or repairs shall be
treated as an Operating Expense and amortized in accordance with the provisions of Paragraph 5(b). 
 (f) Subject to Paragraph 30, Lessor,
Lessor’s agents, employees, contractors and designated representatives, and the holders of any mortgages, deeds of trust or ground leases on the Premises (“Lenders”) shall have the right to enter the Premises at any time in the
case of an emergency, and otherwise at reasonable times, for the purpose of inspecting the condition of the Premises and for verifying compliance by Lessee with this Lease and all Laws, and Lessor shall be entitled to employ experts and/or
consultants in connection therewith to advise Lessor with respect to Lessee’s activities, including but not limited to Lessee’s installation, operation, use, monitoring, maintenance, or removal of any Hazardous Substance on or from the
Premises. The costs and expenses of any such inspections shall be paid by the party requesting same, unless a default or breach of this Lease by Lessee or a violation of Laws or a contamination, caused or materially contributed to by Lessee, is
found to exist or to be imminent, or unless the inspection is requested or ordered by a governmental authority as the result of any such existing or imminent violation or contamination. In such case, Lessee shall upon request reimburse Lessor or
Lessor’s Lender, as the case may be, for the costs and expenses of such inspections. 
 (g) During the Term of this Lease, Lessee shall
comply, at Lessee’s expense, with all of the covenants, conditions, and restrictions affecting the Premises which are recorded in the Official Records of San Mateo County, California, and which are in effect as of the date of this Lease. 

(h) Lessee shall surrender the Premises by the last day of the Term or any earlier termination date, in accordance with Paragraph 13(d) and
this Paragraph 14(h), with all of the portions of the Premises for which Lessee has maintenance and repair responsibility under the terms of this Lease in good operating order, condition, and state of repair, ordinary wear and tear excepted, with
surfaces thereof clean and free of debris. Lessee’s failure to surrender the Premises in accordance with the terms and conditions of this Lease, including, without limitation, this Paragraph 14(h) shall be deemed to be a material default under
the Lease. “Ordinary wear and tear” shall not include any damage or deterioration that would have been prevented by good maintenance practice or by Lessee performing all of its obligations under this Lease. Notwithstanding the foregoing,
prior to the last day of the Term (or earlier termination of the Lease), Lessee shall (i) restore all walls in the Premises to the same condition 

  
 -19- 

 
existing immediately following completion of the Tenant Improvements, including patching and sanding all holes to match the original texture of the walls and painting; (ii) replace any
broken, chipped, stained or discolored ceiling tiles in the Premises to match the existing tiles; and (iii) vacuum and steam clean all carpets. In addition to the foregoing, the obligations of Lessee shall include the repair of any damage
occasioned by the installation, maintenance, or removal of Lessee’s trade fixtures, furnishings, equipment, and alterations, and the restoration by Lessee of the Premises to its condition upon completion of the Tenant Improvements (Lessee shall
not be required to remove any of the Tenant Improvements) (A) if Lessor’s consent to alteration, additions or improvements was conditioned upon such removal and restoration upon expiration or sooner termination of the Lease term pursuant
to Paragraph 14(d), or (B) if Lessee made any such alterations, additions, or improvements without obtaining Lessor’s prior written consent in breach of Paragraph 14(d), and within a reasonable time prior to the expiration or sooner
termination of the Term Lessor gives written notice to Lessee requiring Lessee to perform such removal and restoration. Prior to the expiration of the term of this Lease or any earlier termination date, Lessee shall, at Lessee’s expense, obtain
written closure reports from the San Mateo County Health Department and from the Menlo Park Fire Protection District with respect to any Hazardous Materials used, stored, or released by Lessee on or about the Premises. Both written closure reports
shall provide written certification that all Hazardous Materials for which Lessee is responsible under the terms of this Lease have been removed from the Premises and that no further action is required in connection with the closure of the Premises.
Any removal and remediation of Hazardous Materials by Lessee shall be certified in writing as (1) complete and (2) having been properly performed, by the San Mateo County Health Department and the Menlo Park Fire Protection District and a
copy of such written certifications shall be delivered by Lessee to Lessor no later than the last day of the Term of this Lease. 
 15.
Utilities and Services. 
 (a) Lessor shall contract for and pay for, and Lessee shall reimburse Lessor therefor pursuant to Paragraph
5 as an Operating Expense, all electricity, gas, water, heat and air conditioning service, refuse pick-up, sewer charges, and all other utilities or services supplied to or consumed by Lessee, its agents,
employees, contractors, and invitees on or about the Premises, excluding telephone and data service to the Building for which Lessee shall contract and pay directly. Lessor, at its sole cost and expense shall ensure that electricity in the Premises
in Building 5 and Building 6 are separately metered prior to the Commencement Date and shall provide Lessee with copies of any utility bills and invoices for services upon written request therefor. Lessee may notify Lessor of its intent to contract
for and pay for its own janitorial services for the interior of the Premises and provided such janitorial service meets Lessor’s standards for “Class A” service provided elsewhere in the Building as reasonably determined by
Lessor, Lessor will permit Lessee to contract for its own janitorial service. 
 (b) Lessor shall not be liable to Lessee for any
interruption or failure of any utility services to the Building or the Premises which is not caused by the active negligence or willful acts of Lessor. Lessee shall not be relieved from the performance of any covenant or agreement in this Lease
because of any such failure. Lessor shall make all repairs to the Premises required to restore such services to the Premises and the cost thereof shall be payable by Lessee pursuant to Paragraph 5 as a current Operating Expense, or as a capital
improvement which is amortized over its useful life (together with interest thereon) as an Operating Expense in accordance with generally accepted accounting principles as described in Paragraph 5(b); provided, however, if such failure is caused by
the active negligence or willful acts of Lessor, then Lessor shall bear such costs. 

  
 -20- 

 16. Liens. Lessee agrees to keep the Premises free from all liens arising out of any
work performed, materials furnished, or obligations incurred by Lessee. Lessee shall give Lessor at least ten (10) calendar days prior written notice before commencing any work of improvement on the Premises, the contract price for which
exceeds Ten Thousand and 00/100 Dollars ($10,000.00). Lessor shall have the right to post notices of non-responsibility with respect to any such work. If Lessee shall, in good faith, contest the validity of
any such lien, claim or demand, then Lessee shall, at its sole expense, defend and protect itself, Lessor and the Property against the same, and shall pay and satisfy any such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Property. If Lessor shall require, Lessee shall furnish to Lessor a surety bond satisfactory to Lessor in an amount equal to one and one-half times the amount of such
contested claim or demand, indemnifying Lessor against liability for the same, as required by law for the holding of the Property free from the effect of such lien or claim. 

17. Assignment and Subletting. 

(a) Except as otherwise provided in this Paragraph 17, Lessee shall not assign this Lease, or any interest, voluntarily or involuntarily, and
shall not sublet the Premises or any part thereof, or any right or privilege appurtenant thereto, or suffer any other person (the agents and servants of Lessee excepted) to occupy or use the Premises, or any portion thereof, without the prior
written consent of Lessor in each instance pursuant to the terms and conditions set forth below, which consent shall not be unreasonably withheld conditioned or delayed, subject to the following provisions; provided, however, Lessee shall not assign
this Lease, or any interest, voluntarily or involuntarily, and shall not sublet the Premises or any part thereof, or any right or privilege appurtenant thereto, or suffer any other person (the agents and servants of Lessee excepted) to occupy or use
the Premises, or any portion thereof, if Lessee shall be in default under this Lease following expiration of any applicable notice and cure period. 

(b) Prior to any assignment or sublease which Lessee desires to make, other than a Permitted Transfer (as defined in Paragraph 17(f) below),
Lessee shall provide to Lessor the name and address of the proposed assignee or sublessee, and true and complete copies of all documents relating to Lessee’s prospective agreement to assign or sublease, a copy of a current financial statement
for such proposed assignee or sublessee, and any other relevant information requested by Lessor within five (5) days after receipt of notice of the proposed assignment or sublease and Lessee shall specify all consideration to be received by
Lessee for such assignment or sublease in the form of lump sum payments, installments of rent, or otherwise. For purposes of this Paragraph 17, the term “consideration” shall include all money or other consideration to be received by
Lessee for such assignment or sublease. Within ten (10) days after the receipt of such documentation and other information, Lessor (1) shall notify Lessee in writing that Lessor elects to consent to the proposed assignment or sublease
subject to the terms and conditions hereinafter set forth; (2) shall notify Lessee in writing that Lessor refuses such consent, specifying reasonable grounds for such refusal; or (3) except with respect to a Permitted Transferee, if at the
time Lessee requests that Lessor consent to an assignment or sublease 

  
 -21- 

 
Lessee has vacated the Premises and is not conducting on-going operations in the Building, Lessor may notify Lessee that Lessor elects to terminate this
Lease, provided that with respect to a proposed sublease of a portion of the Premises Lessor’s termination right shall apply only to the proposed sublease space, and specifying the effective date of termination which shall be the same as the
commencement date of the proposed sublease. If Lessor elects to terminate this Lease pursuant to the foregoing provision, upon the effective date of termination (unless prior to such date Lessee withdraws its request for consent in writing, in which
case no termination shall occur), Lessor and Lessee shall each be released and discharged from any liability or obligation to the other under this Lease accruing thereafter with respect to the Premises or the portion thereof to which the termination
applies, except for any obligations then outstanding and except for any indemnity obligations which survive the expiration or termination of this Lease by the express terms hereof, and Lessee agrees that Lessor may enter into a direct lease with
such proposed assignee or sublessee without any obligation or liability to Lessee. 
 In deciding whether to consent to any proposed
assignment or sublease, Lessor may take into account whether reasonable conditions have been satisfied, including, but not limited to, the following: 

(1) In Lessor’s reasonable judgment, the proposed assignee or subtenant is engaged in such a business, that the Premises, or the relevant
part thereof, will be used in such a manner which complies with Paragraph 8 hereof entitled “Use” and Lessee or the proposed assignee or sublessee submits to Lessor documentary evidence reasonably satisfactory to Lessor that such proposed
use constitutes a permitted use of the Premises pursuant to the ordinances and regulations of the City of Menlo Park; 
 (2) The proposed
assignee or subtenant is a reputable entity or individual with sufficient financial net worth so as to reasonably indicate that it will be able to meet its obligations under this Lease or the sublease in a timely manner; 

(3) If at the time of the proposed transfer, Lessor has substantially similar space available for rent in the Menlo Business Park, the
proposed assignee or subtenant is not a tenant of the Building or any other building in the Menlo Business Park; and 
 (4) The proposed
assignment or sublease is approved by Lessor’s mortgage lender if such lender has the right to approve or disapprove proposed assignments or subleases. Lessor shall use its good faith efforts to obtain such approval from its lender within ten
(10) days after receipt by Lessor of Lessee’s written request for consent and the documentation and information referred to in the first sentence of Paragraph 17(b) above. 

(c) As a condition to Lessor’s granting its consent to any assignment or sublease, except with respect to any Permitted Transferees,
(1) Lessor may require that Lessee pay to Lessor, as and when received by Lessee, fifty percent (50%) of the amount of any excess of the consideration to be received by Lessee in connection with said assignment or sublease over and above the
Monthly Base Rent and Additional Rent fixed by this Lease and payable by Lessee to Lessor, after deducting only (A) a standard leasing commission payable by Lessee in consummating such assignment or sublease, (B) the cost of reasonable
tenant improvements performed specifically for the sublease and required to be made to the Premises to effectuate 

  
 -22- 

 
the sublease, provided that such improvements are performed in compliance with Paragraph 14(d) of this Lease, and (C) reasonable attorneys’ fees incurred by Lessor in negotiating and
reviewing the assignment or sublease documentation; and (2) Lessee and the proposed assignee or sublessee shall demonstrate to Lessor’s reasonable satisfaction that each of the criteria referred to in subparagraph (b) above is
satisfied. 
 (d) Each assignment or sublease agreement to which Lessor has consented shall be an instrument in writing in form satisfactory
to Lessor, and shall be executed by both Lessee and the assignee or sublessee, as the case may be. Each such assignment or sublease agreement shall recite that it is and shall be subject and subordinate to the provisions of this Lease, that the
assignee or sublessee accepts such assignment or sublease, that Lessor’s consent thereto shall not constitute a consent to any subsequent assignment or subletting by Lessee or the assignee or sublessee, and, except as otherwise set forth in a
sublease approved by Lessor, agrees to perform all of the obligations of Lessee hereunder (to the extent such obligations relate to the portion of the Premises assigned or subleased), and that the termination of this Lease shall, at Lessor’s
sole election, constitute a termination of every such assignment or sublease. 
 (e) In the event Lessor shall consent to an assignment or
sublease, Lessee shall nonetheless remain primarily liable for all obligations and liabilities of Lessee under this Lease, including but not limited to the payment of rent. 

(f) Notwithstanding the foregoing, Lessee may, without Lessor’s prior written consent and without any participation by Lessor in
assignment and subletting proceeds, but with prior notice and documentation, as required pursuant to this Paragraph 17(f) provided to Lessor (unless applicable law prohibits prior disclosure in which case Lessee shall give written notice and
documentation to Lessor as soon as such applicable law permits), sublet a portion or the entire Premises or assign this Lease to (i) a subsidiary, affiliate, division or corporation controlled or under common control with Lessee
(“affiliate”); (ii) to a successor corporation related to Lessee by merger, consolidation or reorganization; or (iii) to a purchaser of substantially all of Lessee’s business operations conducted on the Premises (each such
transaction referred to herein as a “Permitted Transfer” and each of the foregoing transferees referred to herein as a “Permitted Transferee”), provided that any such Permitted Transferee shall have a current
verifiable net worth prior to the transfer at least equal to that of Lessee on the Commencement Date of this Lease, or, if less, financial resources sufficient, in Lessor’s reasonable good faith judgment, to perform the obligations under the
assignment or sublease, as applicable. Lessee’s foregoing rights in this Paragraph 17(f) to assign this Lease or to sublease all or a portion of the entire Premises shall be subject to the following conditions: (1) Lessee shall not be in
default hereunder past any applicable notice and cure period; (2) in the case of an assignment or subletting to an affiliate, Lessee shall remain liable to Lessor hereunder if Lessee is a surviving entity; (3) the transferee or successor
entity shall expressly assume in writing all of Lessee’s obligations hereunder; and (4) Lessee shall provide Lessor with prior notice of such proposed transfer and deliver to Lessor all documents reasonably requested by Lessor relating to
such transfer (subject to the limitation set forth in the fourth line of this section), including but not limited to documentation sufficient to establish such proposed transferee’s current verifiable net worth prior to the transfer at least
equal to that of Lessee on the Commencement Date of this Lease, or, if less, financial resources sufficient, in Lessor’s reasonable good faith judgment, to perform the obligations under the assignment or sublease, as applicable. 

  
 -23- 

 (g) Neither the sale nor transfer of Lessee’s capital stock shall be deemed an
assignment, subletting, or other transfer of this Lease or the Premises, provided, that in the event of the sale, transfer or issuance of Lessee’s securities to an affiliate or in connection with a transaction described in Paragraph 17(f), the
conditions set forth in Paragraph 17(f) shall apply. 
 (h) Subject to the provisions of this Paragraph 17 any assignment or sublease (if
such consent is required hereunder) without Lessor’s prior written consent shall at Lessor’s election be void. The consent by Lessor to any assignment or sublease shall not constitute a waiver of the provisions of this Paragraph 17,
including the requirement of Lessor’s prior written consent, with respect to any subsequent assignment or sublease. If Lessee shall purport to assign this Lease, or sublease all or any portion of the Premises, or permit any person or persons
other than Lessee to occupy the Premises, without Lessor’s prior written consent (if such consent is required hereunder), Lessor may collect rent from the person or persons then or thereafter occupying the Premises and apply the net amount
collected to the rent reserved herein, but no such collection shall be deemed a waiver of Lessor’s rights and remedies under this Paragraph 17, or the acceptance of any such purported assignee, sublessee, or occupant, or a release of Lessee
from the further performance by Lessee of covenants on the part of Lessee herein contained. 
 (i) Lessee shall not hypothecate or encumber
its interest under this Lease or any rights of Lessee hereunder, or enter into any license or concession agreement respecting all or any portion of the Premises, without Lessor’s prior written consent which consent Lessor may grant or withhold
in Lessor’s absolute discretion without any liability to Lessee. Lessee’s granting of any such encumbrance, license, or concession agreement shall constitute an assignment for purposes of this Paragraph 17. 

(j) In the event of any sale or exchange of the Premises by Lessor and assignment of this Lease by Lessor, Lessor shall, upon providing Lessee
with written confirmation that the assignee has assumed all obligations of Lessor under this Lease and Lessor has delivered any Security Deposit held by Lessor to Lessor’s successor in interest, be and hereby is entirely relieved of all
liability under any and all of Lessor’s covenants and obligations contained in or derived from this Lease with respect to the period commencing with the consummation of the sale or exchange and assignment. 

(k) Lessee hereby acknowledges that the foregoing terms and conditions are reasonable and, therefore, that Lessor has the remedy described in
California Civil Code Section 1951.4 (Lessor may continue the Lease in effect after Lessee’s breach and abandonment and recover rent as it becomes due, if Lessee has the right to sublet or assign, subject only to reasonable limitations).

  
 -24- 

 18. Non-Waiver. 

(a) No waiver of any provision of this Lease shall be implied by any failure of Lessor to enforce any remedy for the violation of that
provision, even if that violation continues or is repeated. Any waiver by Lessor of any provision of this Lease must be in writing. 
 (b) No
receipt of Lessor of a lesser payment than the rent required under this Lease shall be considered to be other than on account of the earliest rent due, and no endorsement or statement on any check or letter accompanying a payment or check shall be
considered an accord and satisfaction. Lessor may accept checks or payments without prejudice to Lessor’s right to recover all amounts due and pursue all other remedies provided for in this Lease. 

Lessor’s receipt of any rent or other payment from Lessee after giving notice to Lessee terminating this Lease shall in no way reinstate,
continue, or extend the Term or affect the termination notice given by Lessor before the receipt of such rent or payment. After serving notice terminating this Lease, filing an action, or obtaining final judgment for possession of the Premises,
Lessor may receive and collect any rent, and the payment of that rent shall not waive or affect such prior notice, action, or judgment. 

19. Holding Over. Lessee shall vacate the Premises and deliver the same to Lessor upon the expiration or sooner termination of this
Lease. In the event of holding over by Lessee after the expiration or termination of this Lease, such holding over shall be on a month-to-month tenancy and all of the
terms and provisions of this Lease shall be applicable during such period, except that in addition to the payment of Additional Rent, Lessee shall pay Lessor as Monthly Base Rent during such holdover an amount equal to the greater of (i) one
hundred fifty percent (150%) of the Monthly Base Rent in effect at the expiration of the term, or (ii) the then market rent for comparable research and development/office space. If such holdover is without Lessor’s written consent, Lessee
shall be liable to Lessor for all costs, expenses, and consequential damages incurred by Lessor as a result of such holdover, including but not limited to damages resulting from Lessor’s inability to timely deliver possession of the Premises to
a new tenant. The rental payable during such holdover period without Lessor’s written consent shall be payable to Lessor on demand. 

20. Damage or Destruction. 

(a) In the event of a total destruction of the Building during the term from any cause, either party may elect to terminate this Lease by
giving written notice of termination to the other party within thirty (30) days after the casualty occurs. A total destruction shall be deemed to have occurred for this purpose if the Building or the Premises that are the subject of this Lease
are destroyed to the extent of seventy-five percent (75%) or more of the replacement cost thereof. If the Lease is not terminated, Lessor shall repair and restore the Premises in a diligent manner and this Lease shall continue in full force and
effect, except that Monthly Base Rent and Additional Rent of the Premises which are the subject of this Lease shall be abated in accordance with Paragraph 20(d) below. 

  
 -25- 

 (b) In the event of a partial destruction of the Building or the Premises to an extent less
than seventy-five percent (75%) of the replacement cost thereof, and if Lessor reasonably believes that the damage thereto can be repaired, reconstructed, or restored with reasonable diligence within a period of one hundred eighty (180) days
after the date of issuance of any necessary permits to complete the repair of the Premises (without payment of overtime or other premiums), there are at least twelve (12) months remaining in the term of this Lease, and the casualty is from a
cause which is insured under Lessor’s “all risk” property insurance, or is insured under any other coverage then carried by Lessor, Lessor shall forthwith repair the same, and this Lease shall continue in full force and effect, except
that Monthly Base Rent and Additional Rent shall be abated in accordance with Paragraph 20(d) below. If any of the foregoing conditions are not met, Lessor shall have the option of either repairing and restoring the Building and Improvements, or
terminating this Lease by giving written notice of termination to Lessee within sixty (60) days after the casualty. Notwithstanding anything to the contrary contained in this Paragraph 20, Lessor shall not have the right to terminate this Lease
if the cost to repair the damage to the Building or to restore the Premises would cost less than five percent (5%) of the replacement cost of the Building, regardless of whether or not the casualty is insured provided that there are at least twelve
(12) months remaining in the term of this Lease. 
 (c) Lessor’s election to repair and restore the Building and Improvements or to
terminate this Lease, shall be made and written notice thereof shall be given to Lessee within sixty (60) days after the casualty. Notwithstanding the foregoing, (1) Lessee may terminate this Lease by written notice to Lessor if Lessor has
not obtained all necessary governmental permits for the restoration and commenced construction of the restoration within sixty (60) days after the casualty; or (2) if Lessor elects to repair and restore the Building and Improvements under
Paragraph 20(b) above, but the repairs and restoration are not substantially completed within two hundred forty (240) days after the date of the casualty, Lessee may terminate this Lease by written notice to Lessor given within thirty
(30) days after the expiration of said period of two hundred forty (240) days after the date of the casualty, provided that the repairs and restoration are not substantially completed prior to the receipt by Lessor of such notice of
termination. 
 (d) In the event of repair, reconstruction, or restoration as provided herein, the Monthly Base Rent and Additional Rent
shall be abated proportionally in the ratio which the Lessee’s use of all or a portion of the Premises is impaired and Lessee does not so use for the conduct of its business such portion of the Premises impaired during the period of such
repair, reconstruction, or restoration, from the date of the casualty until such repair, reconstruction or restoration is substantially completed. 

(e) With respect to any destruction of the Building and Improvements which Lessor is obligated to repair, or may elect to repair, under the
terms of this Paragraph 20, the provisions of Section 1932, Subdivision 2, and of Section 1933, Subdivision 4, of the Civil Code of the State of California are waived by the parties. Lessor’s obligation to repair and restore the
Building and Improvements shall include the Tenant Improvements referred to in Paragraph 13(a). Lessor’s time for completion of the repairs and restoration of the Building and Improvements referred to above shall be extended by a period equal
to any delays (“force majeure delays”) caused by strikes, labor disputes, unavailability of materials, inclement weather, circumstances not within Lessor’s control, or acts of God, but in no event by more than sixty (60) days.

  
 -26- 

 (f) In the event of termination of this Lease pursuant to any of the provisions of this
Paragraph 20, the Monthly Base Rent and Additional Rent shall be apportioned on a per diem basis and shall be paid to the date of the casualty. In no event shall Lessor be liable to Lessee for any damages resulting to Lessee from the occurrence of
such casualty, or from the repairing or restoration of the Building and Improvements, or from the termination of this Lease as provided herein, nor shall Lessee be relieved thereby from any of Lessee’s obligations hereunder, except to the
extent and upon the conditions expressly set forth in this Paragraph 20. 
 21. Eminent Domain. 

(a) If the whole or any substantial part of the Property is taken or condemned by any competent public authority for any public use or purpose,
the term of this Lease shall end upon the earlier to occur of the date when the possession of the part so taken shall be required for such use or purpose or the vesting of title in such public authority. Rent shall be apportioned as of the date of
such termination. Any award arising from the condemnation of any portion of the Property or the settlement thereof shall belong to and be paid to Lessor. However, Lessee may file a separate claim at Lessee’s sole cost and expense for
(i) leasehold improvements installed at Lessee’s expense or other property owned by Lessee, and (ii) reasonable costs of moving by Lessee to another location in San Mateo County or surrounding areas within the San Francisco Bay Area.
In all events, Lessor shall be solely entitled to any award with respect to the real property, including the bonus value of the leasehold. 

(b) If there is a partial taking of the Property by eminent domain which is not a substantial part of the Property and the Premises remain
reasonably suitable for continued use and occupancy by Lessee for the purposes referred to in Paragraph 8, Lessor shall complete any necessary repairs in a diligent manner and this Lease shall remain in full force and effect with a just and
proportionate abatement of the Monthly Base Rent and Additional Rent, based on the extent to which Lessee’s use of the Premises is completely impaired thereafter. If after a partial taking, the Premises are not reasonably suitable for
Lessee’s continued use and occupancy for the uses permitted herein, Lessee may terminate this Lease effective on the earlier of the date title vests in the public authority or the date possession is taken. Subject to the provisions of Paragraph
21(a), the entire award for such taking shall be the property of Lessor. 
 22. Remedies. If Lessee fails to make any payment of rent
or any other sum due under this Lease for five (5) days after receipt by Lessee of written notice from Lessor; or if Lessee fails to comply with any term, provision or covenant of this Lease and does not cure such failure within fifteen
(15) days after receipt by Lessee of written notice from Lessor or such shorter time period specified in this Lease (unless such default is incapable of cure within fifteen (15) days and Lessee commences cure within fifteen (15) days and
thereafter diligently prosecutes the cure to completion within a reasonable time, not to exceed ninety (90) days); or if Lessee’s interest herein, or any part thereof, is assigned or transferred, either voluntarily or by operation of law
(except as expressly permitted by other provisions of this Lease); or if Lessee makes a general assignment for the benefit of its creditors; or if this Lease is rejected (i) by a bankruptcy trustee for Lessee, (ii) by Lessee as debtor in
possession, or (iii) by failure of Lessee 

  
 -27- 

 
as a bankrupt debtor to act timely in assuming or rejecting this Lease; then any of such events shall constitute an event of default and breach of this Lease by Lessee and Lessor may, at its
option, elect the remedies specified in either subparagraph (a) or (b) below. Any such rejection of this Lease referred to above shall not cause an automatic termination of this Lease. Whenever in this Lease reference is made to a default by
Lessee, such reference shall refer to an event of default as defined in this Paragraph 22. 
 (a) Lessor may repossess the Premises and
remove all persons and property therefrom. If Lessor repossesses the Premises because of a breach of this Lease, this Lease shall terminate and Lessor may recover from Lessee: 

(1) the worth at the time of award of the unpaid rent which had been earned at the time of termination including interest thereon at a rate
equal to the discount rate established by the Federal Reserve Bank of San Francisco for member banks, plus one percent (1%), or the maximum legal rate of interest, whichever is less, from the time of termination until paid; 

(2) the worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that Lessee proves could have been reasonably avoided, including interest thereon at a rate equal to the Federal discount rate plus one percent (1%) per annum, or the maximum legal rate of interest,
whichever is less, from the time of termination until paid; 
 (3) the worth at the time of award of the amount by which the unpaid rent for
the balance of the term after the time of award exceeds the amount of such rental loss for the same period that Lessee proves could be reasonably avoided discounted at the discount rate established by the Federal Reserve Bank of San Francisco for
member banks at the time of the award plus one percent (1%); and 
 (4) any other amount necessary to compensate Lessor for all the
detriment proximately caused by Lessee’s breach or by Lessee’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom. 

(b) If Lessor does not repossess the Premises, then this Lease shall continue in effect for so long as Lessor does not terminate Lessee’s
right to possession and Lessor may enforce all of its rights and remedies under this Lease, including the right to recover the rent and other sums due from Lessee hereunder. For the purposes of this Paragraph 22, the following do not constitute a
repossession of the Premises by Lessor or a termination of the Lease by Lessor: 
 (1) Acts of maintenance or preservation by Lessor or
efforts by Lessor to relet the Premises; or 
 (2) The appointment of a receiver by Lessor to protect Lessor’s interests under this
Lease. 

  
 -28- 

 (c) Lessor’s failure to perform or observe any of its obligations under this Lease or
to correct a breach of any warranty or representation made in this Lease within thirty (30) days after receipt of written notice from Lessee setting forth in reasonable detail the nature and extent of the failure referencing pertinent Lease
provisions or if more than thirty (30) days is required to cure the breach, Lessor’s failure to begin curing within the thirty (30) day period and diligently prosecute the cure to completion, shall constitute a default. If Lessor
commits a default, Lessee’s sole remedy shall be to institute an action against Lessor for damages or for equitable or injunctive relief, but Lessee shall not have the right to punitive damages, consequential damages, rent abatement, offset
against rent, or to terminate this Lease in the event of any default by Lessor. 
 (d) All covenants and agreements to be performed by Lessee
under this Lease shall be at its sole cost and expense and without abatement of rent or other sums due under this Lease, unless otherwise specified in this Lease. If Lessee shall fail to pay any sum of money required to be paid by Lessee under this
Lease or shall fail to perform any other act on Lessee’s part to be performed under this Lease within the time periods described in the first paragraph of Paragraph 22(a), Lessor may, but shall not be obligated so to do and without waiving or
releasing Lessee from any obligations of Lessee, make any such payment or perform any such other act on Lessee’s part to be made or performed as provided in this Lease. All sums paid by Lessor, whether to fulfill Lessee’s unfulfilled
payment obligations, to perform Lessee’s unfulfilled performance obligations, or to compel Lessee to fulfill or perform its obligations under this Lease, and all incidental costs, including attorneys’ fees, plus an administrative fee of
five percent (5%) of all amounts so expended by Lessor, shall be deemed to be Additional Rent hereunder and shall be payable to Lessor upon demand. 

23. Lessee’s Personal Property. If any personal property of Lessee remains on the Premises after (1) Lessor terminates this
Lease pursuant to Paragraph 22 above following an event of default by Lessee, or (2) after the expiration of the Lease Term or after the termination of this Lease pursuant to any other provisions hereof, Lessor shall give written notice thereof
to Lessee pursuant to applicable law. Lessor shall thereafter release, store, and dispose of any such personal property of Lessee in accordance with the provisions of applicable law. 

24. Notices. All notices, demands, consents or approvals (collectively, “Notices”) which may or are required to be given by
either party to the other under this Lease shall be in writing and shall be deemed to have been fully given (a) when received or refused, if personally delivered, (b) upon sender’s written confirmation of facsimile transmission to the
fax numbers set forth below; provided that any facsimile confirmed as received after 5:00 Pacific Standard Time shall be deemed received the next day and further provided that such evidence of confirmation and notice is also promptly delivered by
one of the methods described in subsections (a), (c) or (d) of this Paragraph 24, (c) seventy two (72) hours after being deposited in the United States mail, postage prepaid, sent by Certified or Registered Mail, or (d) twenty-four
(24) hours after being deposited with a nationally recognized overnight courier service. Each Notice shall be addressed to Lessor and Lessee at the following address or facsimile number, or to such place as either party may from time to time
designate in a written notice to the other party:

regulations and shall be subject to Lessor’s approval as to the specific location, size and design thereof. The cost of the installation of Lessee’s signage on the glass near the front entrance to the Building and within the interior of

27. Real Estate Brokers. Lessee’s broker is Newmark Cornish and Carey (“Lessee’s Broker”) and Lessor’s
broker is Kidder Matthews (“Lessor’s Broker” and collectively with Lessee’s Broker, the “Brokers”). Lessor shall pay a leasing commission to the Brokers pursuant to a separate agreement. Each party
represents and warrants to the other party that it has not had any dealings with any real estate broker, finder, or other person with respect to this Lease other than Lessee’s Broker and Lessor’s Broker and each party shall hold harmless
the other party from all damages, expenses, and liabilities resulting from any claims that may be asserted against the other party by any broker, finder, or other person with whom the other party has or purportedly has dealt, other than the above
named brokers. 

  
 -30- 

 28. Parking. Lessee shall have the right to the nonexclusive use of one hundred nine
(109) unreserved on-site vehicular parking spaces on the Land at no additional cost to Lessee in the parking area for the Building or nearby parking areas in Menlo Business Park, subject to such rules and
regulations for such parking facilities which may be established or altered by Lessor at any time from time to time during the Lease Term, provided that such rules and regulations shall not unreasonably interfere with Lessee’s parking rights.
Vehicles of Lessee or its employees shall not park in driveways or occupy parking spaces or other areas reserved for deliveries, or loading or unloading. 

29. Subordination; Attornment. 

(a) This Lease, without any further instrument, shall at all times be subject and subordinate to the lien of any and all mortgages and deeds of
trust which may now or hereafter be placed on, against or affect Lessor’s estate in the real property of which the Premises form a part, and to all advances made or hereafter to be made upon the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. 
 (b) In confirmation of such subordination, Lessee covenants and agrees
to execute and deliver within ten (10) days of Lessor’s request any certificate or other instrument which Lessor may reasonably deem proper to evidence such subordination in commercially reasonable form (which document recognizes
Lessee’s rights under this Lease), without expense to Lessee; provided, however, that if any person or persons purchasing or otherwise acquiring the real property of which the Premises form a part by any sale, sales and/or other proceedings
under such mortgages and/or deeds of trust, shall elect to continue this Lease in full force and effect in the same manner and with like effect as if such person or persons had been named as Lessor herein, then this Lease shall continue in full
force and effect as aforesaid, and Lessee hereby attorns and agrees to attorn to such person or persons in writing upon request. 
 (c) If
Lessee is notified in writing of Lessor’s default under any deed of trust affecting the Premises and if Lessee is instructed in writing by the party giving notice to make Lessee’s rental payments to such beneficiary, Lessee shall comply
with such request without liability to Lessor (and with full credit of any amounts paid to such party by Lessee to the corresponding amounts owed to Lessor) until Lessee receives written confirmation that such default has been cured by Lessor and
that the deed of trust has been reinstated. 
 30. No Termination Right. Lessee shall not have the right to terminate this Lease as a
result of any default by Lessor, and Lessee’s remedies in the event of a default by Lessor shall be limited to the remedy set forth in Paragraph 22(c). Lessee expressly waives the defense of constructive eviction. 

31. Lessor’s Entry. Except in the case of an emergency and except for permitted entry during Lessee’s normal working hours,
both of which may occur without prior notice to Lessee, Lessor and Lessor’s agents shall provide Lessee with at least twenty-four (24) hours’ notice prior to entry of the Premises. Lessor may enter the Premises for any reasonable
purpose related to Lessor’s ownership of the Property. Such entry by Lessor and Lessor’s agents shall not impair Lessee’s operations more than reasonably necessary and shall comply with Lessee’s reasonable security measures, if
any. Lessor and Lessor’s agents shall at all times be 

  
 -31- 

 accompanied by Lessee during any such entry except in case of emergency and except for janitorial work.
Lessor may enter the Premises at any time without prior notice to Lessee if the Premises are vacant, if Lessee is no longer conducting its ordinary business at the Premises, or if Lessee has made a general assignment for the benefit of creditors.

 32. Attorneys’ Fees. If any action at law or in equity shall be brought to recover any rent under this Lease, or for or on
account of any breach of or to enforce or interpret any of the provisions of this Lease or for recovery of the possession of the Premises, the prevailing party shall be entitled to recover from the other party costs of suit and reasonable
attorneys’ fees, the amount of which shall be fixed by the court and shall be made a part of any judgment rendered. 
 33. Quiet
Enjoyment. Upon payment by Lessee of the rent for the Premises and the observance and performance of all of the covenants, conditions, and provisions on Lessee’s part to be observed and performed under this Lease within applicable notice
and cure periods, Lessee shall have quiet enjoyment and possession of the Premises for the entire term hereof subject to all of the provisions of this Lease. 

34. Financial Information. Lessee represents and warrants to Lessor that all financial and other information that it has provided to
Lessor prior to the date of this Lease is true, correct and complete. 
 35. SDN List. Lessee represents and warrants to Lessor that
Lessee is not, and the entities or individuals that constitute Lessee, that may own or control Lessee, or that may be owned or controlled by Lessee (in all cases, other than through the ownership of publicly traded, direct or indirect ownership
interests) (each a “Subject Lessee Party”) are not, (i) in violation of any laws relating to terrorism or money laundering, or (ii) among the individuals or entities identified on any list compiled pursuant to Executive
Order 13224 or published by the Office of Foreign Assets Control, U.S. Department of the Treasury (“OFAC”) for the purpose of identifying suspected terrorists or on the most current list published by the OFAC at its official
website, http://www.treas.gov/ofac/tllsdn.pdf or any replacement website or other replacement official publication of such list which identifies an “Specially Designated National” or “blocked person” (either of which are referred
to herein as a “SDN”). If at any time during the Lease Term Lessor discovers that Lessee has breached the foregoing representations and warranties, or Lessor reasonably believes that Lessee or any Subject Lessee Party is in
violation of any laws relating to terrorism or money laundering or that Lessee or any Subject Lessee Party is identified as an SDN, Lessee shall be deemed in default under this Lease following three (3) days written notice from Lessor to Lessee
unless, within such three day period, Lessee delivers written evidence, reasonably acceptable to Lessor, that Lessee is not in violation of such laws or that Lessee (or the Subject Lessee Party, as applicable) is not a person or entity identified as
an SDN. Except as otherwise expressly provided in the foregoing sentence, and without further notice, any default by Lessee under this Paragraph 35 shall be deemed an incurable default by Lessee and, in addition to any other rights and remedies that
Lessor may have upon such default, Lessor shall also have the right to immediately terminate this Lease upon written notice to Lessee and recover possession of the Premises. 

  
 -32- 

 36. Right of First Offer. If at any time during the initial Term space in the
remainder of Building 6 adjacent to the Building 6 Premises becomes available for lease (the “Available Space”), then Lessor, prior to entering into a lease with any third party respecting the Available Space, shall first offer to
lease the same to Lessee by delivery of notice to Lessee (the “Availability Notice”). The Availability Notice shall set forth the terms upon which Lessor would be willing to lease to Lessee the Available Space, as determined by
Lessor in its sole discretion. Lessee shall have ten (10) days after receipt of the Availability Notice to unconditionally accept in writing or reject the terms set forth in the Availability Notice it being understood that Lessee’s failure
to respond within the foregoing period shall be deemed a rejection of such terms. If Lessee does not unconditionally accept in writing the terms set forth in the Availability Notice within such ten (10) day period, then Lessee’s rights
under this Paragraph shall lapse and terminate and Lessor shall be entitled to lease the Available Space to any other party on such terms as Lessor desires; provided that the rental rate (taking into account adjustments for any differences between so-called “net” leases and “gross” leases) and Lessee improvement allowance, if any, shall not be materially less than that originally offered to Lessee, unless Lessor has first again offered the
Available Space to Lessee for lease on the terms offered to the third party in accordance with the procedures specified above in this Paragraph. If Lessee accepts in writing the terms set forth in the Availability Notice, then for the period
starting on the date of Lessee’s delivery of the Availability Notice to Lessee and ending thirty (30) days thereafter (the “Waiting Period”), Lessor shall not enter into any binding agreement to lease the Available Space
to any other party, provided Lessor shall have the right to market the Available Space for lease. During the Waiting Period, Lessor and Lessee shall negotiate in good faith the terms of a definitive written amendment to this Lease or a new lease (a
“Definitive Lease Agreement”), consistent with the terms set forth in the Availability Notice and otherwise consistent with the terms and conditions set forth in this Lease or reasonably acceptable to Lessor and Lessee. If Lessee
and Lessor fail to execute and deliver a Definitive Lease Agreement within the Waiting Period, then Lessee’s rights under this Paragraph shall lapse and terminate, and Lessor shall be entitled to lease the Available Space to any other party on
such terms as Lessor desires; provided that the rental rate (taking into account adjustments for any differences between so-called “net” leases and “gross” leases) and Lessee improvement
allowance, if any, shall not be materially less than that originally offered to Lessee, unless Lessor has first again offered the Available Space to Lessee for lease on the terms offered to the third party in accordance with the procedures specified
above in this Paragraph. Lessor shall not be required to offer the Available Space to Lessee during any period in which an event of default has occurred and is continuing. Furthermore, unless expressly mentioned and approved in the written consent
of Lessor to any assignment or sublet as provided in this Lease, the right of first offer to lease under this Paragraph 36 is granted for the personal benefit of Personalis, Inc., or a Permitted Transferee and may not be assigned or transferred by
Personalis, Inc. to anyone other than a Permitted Transferee. 
 37. General Provisions. 

(a) Nothing contained in this Lease shall be deemed or construed by the parties hereto or by any third person to create the relationship of
principal and agent or of partnership or of joint venture of any association between Lessor and Lessee, and neither the method of computation of rent nor any other provisions contained in this Lease nor any acts of the parties hereto shall be deemed
to create any relationship between Lessor and Lessee other than the relationship of landlord and tenant. 

  
 -33- 

 (b) Each and all of the provisions of this Lease shall be binding upon and inure to the
benefit of the parties hereto, and except as otherwise specifically provided elsewhere in this Lease, their respective heirs, executors, administrators, successors, and assigns, subject at all times, nevertheless, to all agreements and restrictions
contained elsewhere in this Lease with respect to the assignment, transfer, encumbering, or subletting of all or any part of Lessee’s interest in this Lease. 

(c) The captions of the paragraphs of this Lease are for convenience only and shall not be considered or referred to in resolving questions of
interpretation or construction. 
 (d) This Lease is and shall be considered to be the only agreement between the parties hereto and their
representatives and agents. All negotiations and oral agreements acceptable to both parties have been merged into and are included herein. There are no other representations or warranties between the parties and all reliance with respect to
representations is solely upon the representations and agreements contained in this instrument. 
 (e) The laws of the State of California
shall govern the validity, performance, and enforcement of this Lease. Notwithstanding which of the parties may be deemed to have prepared this Lease, this Lease shall not be interpreted either for or against Lessor or Lessee, but this Lease shall
be interpreted in accordance with the general tenor of the language in an effort to reach an equitable result. 
 (f) Time is of the essence
with respect to the performance of each of the covenants and agreements contained in this Lease. 
 (g) Recourse by Lessee for breach of this
Lease by Lessor shall be expressly limited to the amount of Lessor’s interest in the Property and the rents, issues, insurance, condemnation, and sales proceeds actually received by Lessor, and profits therefrom, and in the event of any such
breach or default by Lessor, Lessee hereby waives the right to proceed against any other assets of Lessor or against any other assets of any manager or member of Lessor. 

(h) Any provision or provisions of this Lease which shall be found to be invalid, void or illegal by a court of competent jurisdiction, shall
in no way affect, impair, or invalidate any other provisions hereof, and the remaining provisions hereof shall nevertheless remain in full force and effect. 

(i) This Lease may be modified in writing only, signed by the parties in interest at the time of such modification. 

(j) Each party represents to the other that the person signing this Lease on its behalf is properly authorized to do so, and in the event this
Lease is signed by an agent or other third party on behalf of either Lessor or Lessee, written authority to sign on behalf of such party in favor of the agent or third party shall be provided to the other party hereto either prior to or
simultaneously with the return to such other party of a fully executed copy of this Lease. 
 (k) No binding agreement between the parties
with respect to the Premises shall arise or become effective until this Lease has been duly executed by both Lessee and Lessor and a fully executed copy of this Lease has been delivered to both Lessee and Lessor. 

  
 -34- 

 (l) Lessor and Lessee acknowledge that the terms and conditions of this Lease constitute
confidential information of Lessor and Lessee. Each party shall use its reasonable good faith efforts to prevent the dissemination orally or in written form, of this Lease, lease proposals, lease drafts, or other documentation containing the terms,
identity of the parties, details or conditions contained herein to any third party without obtaining the prior written consent of the other party, except to the attorneys, accountants, lenders, investors, potential investors, potential business or
merger partners, potential subtenants and assignees, or other authorized business representatives or agents of the parties, or except to the extent required to comply with applicable laws, including any filings by Lessee pursuant to state or federal
securities laws. Neither Lessor nor Lessee shall make any public announcement of the consummation of this Lease transaction without the prior approval of the other party. A violation of this subparagraph (1) shall not permit either party to
terminate this Lease. Nothing in this Paragraph shall prevent Lessor from submitting a copy of this Lease to the Court in connection with any action to enforce the provisions hereof. 

(m) Except as provided in Paragraph 22(c), the rights and remedies that either party may have under this Lease or at law or in equity, upon any
breach, are distinct, separate and cumulative and shall not be deemed inconsistent with each other, and no one of them shall be deemed to be exclusive of any other. 

(n) Lessee waives any claim for consequential damages which Lessee may have against Lessor for breach of or failure to perform or observe the
requirements and obligations created by this Lease. 
 (o) Lessor and Lessee each agree to and they hereby do, to the maximum extent
permitted by law, waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other on any matters whatsoever arising out of or in any way connected with this Lease, the relationship of Lessor
and Lessee, Lessee’s use or occupancy of the Premises and/or any claim of injury or damage, and any statutory remedy. 
 (p) This Lease
shall not be recorded. 
 (q) Whenever this Lease requires an approval, consent, determination, selection or judgment by either Lessor or
Lessee, unless another standard is expressly set forth, such approval, consent, determination, selection or judgment and any conditions imposed thereby shall be reasonable and shall not be unreasonably withheld, conditioned or delayed and, in
exercising any right or remedy hereunder, each party shall at all times act reasonably and in good faith. 
 (r) Energy Use Disclosures.
Tenant acknowledges and agrees that: (a) it has received all disclosures and other documentation or information for the Project required under Section 25402.10 of the California Public Resources Code and its implementing regulations
(“Energy Disclosure Information”), (b) such disclosure information is for the current occupancy and use of the Project, (c) the energy profile of the Project will vary depending on future occupancy/use of the Project, and
(d) Landlord makes no claims, representations or warranties regarding the future Energy Star profile of the Project. Tenant agrees that Landlord has timely complied in full with Landlord’s obligations under the Energy Disclosure
Requirements. 

  
 -35- 

 Tenant acknowledges and agrees that (i) Landlord makes no representation or warranty regarding the
energy performance of the Building or the accuracy or completeness of the Energy Disclosure Information, and (ii) Landlord shall have no liability to Tenant for any errors or omissions in the Energy Disclosure Information. If and to the extent
not prohibited by applicable Laws, Tenant hereby waives any right Tenant may have to receive the Energy Disclosure Information, including, without limitation, any right Tenant may have to terminate this Lease as a result of Landlord’s failure
to disclose such information. Further, Tenant hereby releases Landlord from any and all losses, costs, damages, expenses and/or liabilities relating to, arising out of and/or resulting from the Energy Disclosure Requirements, including, without
limitation, any liabilities arising as a result of Landlord’s failure to disclose the Energy Disclosure Information to Tenant prior to the execution of this Lease. Tenant further acknowledges that pursuant to the Energy Disclosure Requirements,
Landlord may be required in the future to disclose information concerning Tenant’s energy usage to certain third parties, including, without limitation, prospective purchasers, lenders and tenants of the Building (the “Tenant Energy Use
Disclosure”). Tenant hereby (A) consents to all such Tenant Energy Use Disclosures, and (B) acknowledges that Landlord shall not be required to notify Tenant of any Tenant Energy Use Disclosure. Further, Tenant hereby releases
Landlord from any and all losses, costs, damages, expenses and liabilities relating to, arising out of and/or resulting from any Tenant Energy Use Disclosure. The terms of this Section shall survive the expiration or earlier termination of this
Lease.
