 1. GENERAL. 

(a) Successor to and Continuation of Prior Plan. The Plan is intended as the successor to and continuation of the ProteinSimple 2003
Stock Option/Issuance Plan (the “Prior Plan”). Following the Effective Date, no additional stock awards may be granted under the Prior Plan. Any unallocated shares remaining available for issuance pursuant to the exercise of
options or issuance or settlement of stock awards not previously granted under the Prior Plan as of 12:01 a.m. Pacific time on the Effective Date (the “Prior Plan’s Available Reserve”) will cease to be available under
the Prior Plan at such time and will be added to the Share Reserve (as further described in Section 3(a) below) and be then immediately available for issuance pursuant to Stock Awards granted hereunder. In addition, from and after 12:01 a.m.
Pacific time on the Effective Date, all outstanding stock awards granted under the Prior Plan will remain subject to the terms of the Prior Plan; provided, however, that any shares subject to outstanding stock awards granted under the Prior
Plan that (i) expire or terminate for any reason prior to exercise or settlement; (ii) are forfeited, cancelled or otherwise returned because of the failure to meet a contingency or condition required to vest such shares; or (iii) are
reacquired, withheld (or not issued) to satisfy a tax withholding obligation in connection with an award or to satisfy the purchase price or exercise price of a stock award (the “Returning Shares”) will immediately be added
to the Share Reserve (as further described in Section 3(a) below) as and when such shares become Returning Shares, and become available for issuance pursuant to Awards granted hereunder. All Stock Awards granted on or after 12:01 a.m. Pacific
time on the Effective Date of this Plan will be subject to the terms of this Plan. 
 (b) Eligible Stock Award Recipients. Employees,
Directors and Consultants are eligible to receive Stock Awards. 
 (c) Available Stock Awards. The Plan provides for the grant of the
following types of Stock Awards: (i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Stock Appreciation Rights, (iv) Restricted Stock Awards, (v) Restricted Stock Unit Awards and (vi) Other Stock Awards.

 (d) Purpose. The Plan, through the granting of Stock Awards, is intended to help the Company secure and retain the services of
eligible award recipients, provide incentives for such 

  
 1. 








 
persons to exert maximum efforts for the success of the Company and any Affiliate and provide a means by which the eligible recipients may benefit from increases in value of the Common Stock.

 2. ADMINISTRATION. 

(a) Administration by Board. The Board will administer the Plan. The Board may delegate administration of the Plan to a Committee or
Committees, as provided in Section 2(c). 
 (b) Powers of Board. The Board will have the power, subject to, and within the
limitations of, the express provisions of the Plan: 
 (i) To determine (A) who will be granted Stock Awards; (B) when and
how each Stock Award will be granted; (C) what type of Stock Award will be granted; (D) the provisions of each Stock Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or
Common Stock under the Stock Award; (E) the number of shares of Common Stock subject to a Stock Award; and (F) the Fair Market Value applicable to a Stock Award. 

(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 and Stock Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement, in a manner and to the extent it will 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, in whole or in part, the time at which a Stock Award may be exercised or vest (or at which cash or
shares of Common Stock may be issued), including, but not limited to, the discretionary authority, exercisable either at the time shares are issued pursuant to Section 5(m) below or any time while the Company’s repurchase rights with
respect to those shares remain outstanding, to provide that those rights shall automatically terminate in whole or in part on an accelerated basis, and some or all of the shares subject to those terminated rights shall immediately become vested,
upon the occurrence of a Change in Control or another specified event or in the event that Participant’s Continuous Service terminates other than for Misconduct within a designated period of time following a specified event. 

(v) To suspend or terminate the Plan at any time. Except as otherwise provided in the Plan or a Stock Award Agreement, suspension or
termination of the Plan will not impair a Participant’s rights under his or her then-outstanding Stock Award without his or her written consent except as provided in subsection (viii) below. 

(vi) To amend the Plan in any respect the Board deems necessary or advisable, including, without limitation, by adopting amendments
relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to make the 

  
 2. 








 
Plan or Stock Awards granted under the Plan compliant with the requirements for Incentive Stock Options or exempt from or compliant with the requirements for nonqualified deferred compensation
under Section 409A of the Code, subject to the limitations, if any, of applicable law. However, if required by applicable law, and except as provided in Section 9(a) relating to Capitalization Adjustments, the Company will seek stockholder
approval of any amendment of the Plan that (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, (D) materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (E) materially extends the term of the
Plan, or (F) materially expands the types of Stock Awards available for issuance under the Plan. Except as provided in the Plan (including subsection (viii) below) or a Stock Award Agreement, no amendment of the Plan will impair a
Participant’s rights under an outstanding Stock Award 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 a Participant’s rights under any Stock Award will not be impaired by any such amendment unless (A) the Company requests the consent of
the affected Participant, and (B) such Participant consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, the Board may amend the terms of any one or more Stock Awards without the affected
Participant’s consent (A) to maintain the qualified status of the Stock Award as an Incentive Stock Option under Section 422 of the Code; (B) to clarify the manner of exemption from, or to bring the Stock Award into compliance
with, Section 409A of the Code; or (C) to comply with other applicable laws. 
 (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 (provided that Board approval will not be necessary for immaterial modifications to the Plan or any Stock Award Agreement that are required for compliance with the laws
of the relevant foreign jurisdiction). 
 (xi) To effect, with the consent of any adversely affected Participant, (A) the
reduction of the exercise, purchase or strike price of any outstanding Stock Award; (B) the cancellation of any outstanding Stock Award and the grant in substitution therefor of a new (1) Option or SAR, (2) Restricted Stock Award,
(3) Restricted Stock Unit Award, (4) Other Stock 

  
 3. 








 
Award, (5) cash and/or (6) other valuable consideration determined by the Board, in its sole discretion, with any such substituted award (x) covering the same or a different number
of shares of Common Stock as the cancelled Stock Award and (y) granted under the Plan or another equity or compensatory plan of the Company; or (C) any other action that is treated as a repricing under generally accepted accounting
principles. 
 (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 will 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 will thereafter be to the Committee or subcommittee). Any delegation of
administrative powers will be reflected in resolutions, not inconsistent with the provisions of the Plan, adopted from time to time by the Board or Committee (as applicable). The Committee may, at any time, abolish the subcommittee and/or revest in
the Committee any powers delegated to the subcommittee. 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 (1) or more Officers the authority to do one or both of the following:
(i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by applicable law, other Stock Awards) and, to the extent permitted by applicable law, the terms of such Stock Awards, and
(ii) determine the number of shares of Common Stock to be subject to such Stock Awards granted to such Employees; provided, however, that the Board resolutions regarding such delegation will 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. Any such Stock Awards will be granted on the form of Stock Award Agreement most recently approved for use by the
Committee or the Board, unless otherwise provided in the resolutions approving the delegation authority. The Board may not delegate authority to an Officer who is acting solely in the capacity of an Officer (and not also as a Director) to determine
the Fair Market Value pursuant to Section 13(r) below. 
 (e) Effect of Board’s Decision. All determinations,
interpretations and constructions made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons. 

3. SHARES SUBJECT TO THE PLAN. 

(a) Share Reserve.  

(i) Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be
issued pursuant to Stock Awards from and after the Effective Date will not exceed 7,779,453 shares (the “Share Reserve”). The Share Reserve includes (A) the 584,566 shares that were subject to the Prior
Plan’s Available Reserve on the Effective Date, (B) the Returning Shares, if any, in an amount not to exceed 4,828,887 shares (if and when the Returning Shares ever become available for grant under this Plan) and (C) 2,366,000 shares
approved by the Board of Directors on January 28, 2014. 
 (ii) For clarity, the Share Reserve in this Section 3(a) is a
limitation on 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). 

  
 4. 








 (b) Reversion of Shares to the Share Reserve. If a Stock Award or any portion thereof
(i) expires or otherwise terminates without all of the shares covered by such Stock Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than stock), such expiration, termination or
settlement will not reduce (or otherwise offset) the number of shares of Common Stock that may be available for issuance under the Plan. If any shares of Common Stock issued pursuant to a Stock Award are forfeited back to or repurchased by the
Company because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited or repurchased will revert to and again become available for issuance under the Plan. Any shares
reacquired by the Company in satisfaction of tax withholding obligations on a Stock Award or as consideration for the exercise or purchase price of a Stock Award will again become available for issuance under the Plan. 

(c) Incentive Stock Option Limit. Subject to the Share Reserve and 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 will be 27,193,820 shares of Common Stock. 

(d) Source of Shares. The stock issuable under the Plan will 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 424(f) of the Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants;
provided, however, that Stock Awards 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 (i) the
stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code (for example, because the Stock Awards are granted pursuant to a corporate transaction such as a spin off transaction), or
(ii) the Company, in consultation with its legal counsel, has determined that such Stock Awards are otherwise exempt from or alternatively comply with the distribution requirements of Section 409A of the Code. 

(b) Ten Percent Stockholders. A Ten Percent Stockholder will 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. 

  
 5. 








 (c) Consultants. A Consultant will not be eligible for the grant of a Stock Award if, at
the time of grant, either the offer or 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
will be in such form and will contain such terms and conditions as the Board deems appropriate. All Options will 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 will 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, or if an Option is designated as an Incentive
Stock Option but some portion or all of the Option fails to qualify as an Incentive Stock Option under the applicable rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option. The provisions of separate Options or SARs need
not be identical; provided, however, that each Stock Award Agreement will 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 will 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 Ten Percent Stockholders, the exercise or strike price of
each Option or SAR will 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 Stock Award is granted. Notwithstanding the foregoing, an Option or SAR may be granted
with an exercise or strike price lower than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Stock Award if such Stock Award is granted pursuant to an assumption of or substitution for another option or
stock appreciation right pursuant to a Change in Control and in a manner consistent with the provisions of Section 409A of the Code and, if applicable, Section 424(a) of the Code. Each SAR will be denominated in shares of Common Stock
equivalents. 
 (c) Purchase Price for Options. The purchase price of Common Stock acquired pursuant to the exercise of an Option may
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 will 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 use 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; 

  
 6. 








 (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 an 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 will 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. 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 used 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) subject to the consent of the Company at the time of
exercise, by delivering an interest bearing promissory note with such terms (including the interest rate, the requirements for collateral and the terms of repayment) as established by the Company in its sole discretion; provided, however, in
no event may the principal amount of the promissory note exceed the sum of (A) the aggregate exercise price for the shares (less the par value of the shares) plus (B) the Participant’s tax withholding obligations, if any; or 

(vi) in any other form of legal consideration that may be acceptable to the Board and specified in the applicable Stock Award
Agreement. 
 (d) Exercise and Payment of a SAR. To exercise any outstanding SAR, the Participant must provide written notice of
exercise to the Company in compliance with the provisions of the Stock Award Agreement evidencing such SAR. The appreciation distribution payable on the exercise of a SAR 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 SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR, and with respect to which the Participant
is exercising the SAR on such date, over (B) the aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such date. The appreciation distribution 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 Award Agreement evidencing such SAR. 

(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 will determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs will apply: 

(i) Restrictions on Transfer. An Option or SAR will not be transferable except by will or by the laws of descent and distribution (and
pursuant to subsections (ii) and (iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Board may permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax
and securities laws. Except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration. 

  
 7. 








 (ii) Domestic Relations Orders. Subject to the approval of the Board or a duly authorized
Officer, an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulation 1.421-1(b)(2). 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. Subject to the approval of the Board or a duly authorized Officer, a Participant may, by delivering written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, upon the
death of the Participant, will 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, upon the death of the Participant, the
executor or administrator of the Participant’s estate will be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a
beneficiary at any time, including due to any conclusion by the Company that such designation would be inconsistent with the provisions of applicable laws. 

(f) Vesting Generally. The total number of shares of Common Stock subject to an Option or SAR may vest and 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, if a Participant’s Continuous Service terminates (other than for Misconduct and 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) within the 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 applicable Stock Award Agreement, which period will not be less than thirty (30) days if
necessary to comply with applicable laws unless such termination is for Misconduct and (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 applicable time frame, the Option or SAR (as applicable) will terminate. 

  
 8. 








 (h) Extension of Termination Date. Except as otherwise provided in the applicable Stock
Award Agreement or other agreement between the Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Misconduct and 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 will terminate on the earlier
of (i) the expiration of a total period of time (that need not be consecutive) 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 such registration requirements, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Stock Award Agreement. In addition, unless otherwise provided in a Participant’s
Stock Award Agreement, if the sale of any Common Stock received upon exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Misconduct) would violate the Company’s insider trading
policy, then the Option or SAR will terminate on the earlier of (i) the expiration of a period of time (that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the Participant’s
Continuous Service during which the sale of the Common Stock received upon 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, if 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 will not be less than six (6) months if necessary to comply with applicable laws), and (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 applicable time frame, the Option or SAR (as applicable) will
terminate. 
 (j) Death of Participant. Except as otherwise provided in the applicable Stock Award Agreement or other agreement
between the Participant and the Company, if (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
for exercisability 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 

  
 9. 








 
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 twelve (12) months following the date of
death (or such longer or shorter period specified in the Stock Award Agreement, which period will not be less than six (6) months if necessary to comply with applicable laws), and (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 applicable time frame, the Option or SAR (as applicable) will terminate. 

(k) Termination for Misconduct. Except as explicitly provided otherwise in the Participant’s Stock Award Agreement or other
individual written agreement between the Company or any Affiliate and the Participant, if the Participant’s Continuous Service is terminated for Misconduct, the Option or SAR will terminate immediately upon such Participant’s termination
of Continuous Service, and the Participant will 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. If an Option or SAR is granted to an Employee who is a non-exempt employee for purposes of the Fair Labor
Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least six (6) months following the date of grant of the Option or SAR (although the Stock Award may vest prior to such
date). Consistent with the provisions of the Worker Economic Opportunity Act, (i) if such non-exempt Employee dies or suffers a Disability, (ii) upon a Change in Control, or (iii) upon the Participant’s retirement (as such term
may be defined in the Participant’s Stock Award Agreement, in another agreement between the Participant and the Company, or, if no such definition, in accordance with the Company’s then current employment policies and guidelines), the
vested portion of any Options and SARs may be exercised earlier than six (6) 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. To the extent permitted and/or required for compliance with the Worker Economic Opportunity Act to ensure that any income derived by a non-exempt employee in
connection with the exercise, vesting or issuance of any shares under any other Stock Award will be exempt from the employee’s regular rate of pay, the provisions of this Section 5(l) will apply to all Stock Awards and are hereby
incorporated by reference into such Stock Award Agreements. 
 (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(m), 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(m) is not violated, the Company will not be required to exercise its repurchase right until at least sixty (60) days (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. 

  
 10. 








 (n) Right of Repurchase. Subject to the “Repurchase Limitation” in
Section 8(m), 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 will be subject to the
“Repurchase Limitation” in Section 8(m). Except as expressly provided in this Section 5(o) or in the Stock Award Agreement, such right of first refusal will otherwise comply with any applicable provisions of the bylaws of
the Company. 
 6. PROVISIONS OF STOCK AWARDS OTHER THAN
OPTIONS AND SARS. 
 (a) Restricted Stock Awards. Each Restricted Stock Award
Agreement will be in such form and will contain such terms and conditions as the Board deems appropriate. To the extent consistent with the Company’s bylaws, at the Board’s election, shares of Common Stock underlying a Restricted Stock
Award may be (i) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (ii) evidenced by a certificate, which certificate will 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. Each Restricted Stock
Award Agreement will 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, check, bank draft or money order payable
to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) 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(m), 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. 

  
 11. 








 (iv) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock
Award Agreement will be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board will 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. 

(b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement will be in such form and will contain such terms and
conditions as the Board deems 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. Each
Restricted Stock Unit Award Agreement will 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 on 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 of the same terms and conditions of the underlying Restricted
Stock Unit Award Agreement to which they relate. 

  
 12. 








 (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 will 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, will 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 vests must be issued in accordance with a fixed pre-determined schedule. 

(c) Other Stock Awards. Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock,
including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than one hundred percent (100%) of the Fair Market Value of the Common Stock at the time of grant) may be granted either
alone or in addition to Stock Awards provided for under Section 5 and the preceding provisions of this Section 6. Subject to the provisions of the Plan, the Board will have sole and complete authority to determine the persons to whom and
the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock
Awards. 
 7. COVENANTS OF THE COMPANY. 

(a) Availability of Shares. The Company will keep available at all times the number of shares of Common Stock reasonably required to
satisfy then-outstanding Stock Awards. 
 (b) Securities Law Compliance. The Company will 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 will 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 and at a reasonable cost, 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 will 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 will not be eligible for the grant of a Stock Award or the subsequent issuance of cash or Common Stock pursuant to the Stock Award if such grant or
issuance would be in violation of any applicable securities law. 

  
 13. 








 (c) No Obligation to Notify or Minimize Taxes. The Company will 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 will 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 will 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 will 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. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action constituting the grant contain terms (e.g., exercise price, vesting schedule or number of shares)
that are inconsistent with those in the Stock Award Agreement as a result of a clerical error in the papering of the Stock Award Agreement, the corporate records will control and the Participant will have no legally binding right to the incorrect
term in the Stock Award Agreement. 
 (c) Stockholder Rights. No Participant will 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 a Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common Stock under, the Stock Award
pursuant to its terms, and (ii) the issuance of the Common Stock subject to the 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 will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or will 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 Misconduct, (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. 

  
 14. 








 (e) Change in Time Commitment. In the event a Participant’s regular level of time
commitment in the performance of his or her services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time
Employee to a part-time Employee) after the date of grant of any Stock Award to the Participant, the Board has the right in its sole discretion to (x) make a corresponding reduction in the number of shares subject to any portion of such Stock
Award that is scheduled to vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Stock Award. In the event
of any such reduction, the Participant will have no right with respect to any portion of the Stock Award that is so reduced or extended. 

(f) Incentive Stock Option Limitations. 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) (or such
other limit established in the Code) or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not comply
with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 

(g) 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, will be inoperative if (A) 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 (B) 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. 
 (h) 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 

  
 15. 








 
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 cash from a Stock Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Stock Award Agreement. 

(i) Electronic Delivery. Any reference herein to a “written” agreement or document will include any agreement or document
delivered electronically or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the Participant has access). 

(j) 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. 
 (k) Compliance with
Section 409A of the Code. 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 will 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 will be interpreted in accordance with Section 409A of the Code. 

(l) Repurchase Limitation. The terms of any repurchase right will be specified in the Stock Award Agreement. The repurchase price for
vested shares of Common Stock will 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 will 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 will not exercise its repurchase right until at least sixty (60) days (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. 

  
 16. 








 9. ADJUSTMENTS UPON CHANGES IN
COMMON STOCK; OTHER CORPORATE EVENTS. 
 (a)
Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board will 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 will make such adjustments, and its determination will 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) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s
repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service, provided, however, that the Board may, in its
sole discretion, cause some or all Stock Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or
liquidation is completed but contingent on its completion. 
 (c) Change in Control. The following provisions will apply to Stock
Awards in the event of a Change in Control unless otherwise provided in the Stock Award Agreement or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board at the time
of grant of a Stock Award. 
 (i) Options and SARs. 

(1) Immediately following the consummation of any Change in Control, all outstanding Options and SARs will terminate, except to the
extent they are assumed by the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction. 

(2) In the event of a Change in Control: (A) all outstanding repurchase rights will be automatically assigned to the successor
corporation (or parent thereof); (B) such outstanding repurchase rights may be otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction; or (C) any property (including cash payments) issued
with respect to unvested shares may be held in escrow and released no later than as provided by the vesting schedule in effect for the unvested shares pursuant to the Change in Control transaction. Notwithstanding the foregoing, in the event of a
Change in Control the successor corporation (or parent thereof) may elect to not accept assignment of the outstanding repurchase rights, in which case the repurchase rights will terminate automatically and the shares of Common Stock
subject to those terminated rights will immediately become vested shares upon the Change in Control. 

  
 17. 








 (3) Each Option and SAR that is assumed or otherwise continued in effect in connection
with a Change in Control will be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities which would have been issuable to the Participant in consummation of such Change in Control, had the
Option or SAR been exercised immediately prior to such Change in Control. Appropriate adjustments will also be made to (A) the number and class of securities available for issuance under the Plan following the consummation of such Change in
Control and (B) the exercise price payable per share under each outstanding Option and SAR, provided the aggregate exercise price payable for such securities will remain the same. To the extent the holders of Common Stock receive cash
consideration in whole or part for their Common Stock in consummation of the Change in Control, the successor corporation may, in connection with the assumption of the outstanding Options and SARs under this Plan, substitute one or more shares of
its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in such Change in Control transaction. 

(4) Among its discretionary powers, the Board will have the ability to structure an Option and SAR (either at the time the Option or
SAR is granted or at any time while the Option or SAR remains outstanding) so that some or all of the shares subject to that Option or SAR will automatically become vested shares upon the occurrence of: (A) a Change in Control; (B) another
specified event; and/or (C) the Involuntary Termination of the Participant’s Continuous Service within a designated period of time following a specified event. In addition, the Board may provide that one or more of the Company’s
outstanding repurchase rights with respect to some or all of the shares held by the Participant will terminate on an accelerated basis either upon: (A) a Change in Control; (B) another specified event; and/or (C) the Involuntary
Termination of the Participant’s Continuous Service within a designated period of time following a specified event, and the shares subject to those terminated rights will become vested shares at that time. 

(5) The portion of any Incentive Stock Option accelerated in connection with a Change in Control will remain exercisable as an
Incentive Stock Option only to the extent the $100,000 limitation set forth in Section 8(f) is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such option will be exercisable as a Nonstatutory Stock
Option under the federal tax laws. 
 (ii) Restricted Stock Awards. 

(1) Upon the occurrence of a Change in Control: (A) all outstanding repurchase rights will be automatically assigned to the
successor corporation (or parent thereof); (B) the repurchase rights may be otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction; or (C) any property (including cash payments) issued with
respect to the unvested shares may be held in escrow and released no later than as provided by the vesting schedule in effect for the unvested shares pursuant to the terms of the Change in Control transaction. Notwithstanding the foregoing, in the
event of a Change in Control the successor corporation (or parent thereof) may elect to not accept assignment of the outstanding repurchase rights, in which case the repurchase rights will terminate automatically and the shares of
Common Stock subject to those terminated rights will immediately become vested shares upon the Change in Control. 

  
 18. 








 (2) The Board will have the discretionary authority, exercisable either at the time the
unvested shares are issued or any time while the Company’s repurchase rights with respect to those shares remain outstanding, to provide that those rights will automatically terminate in whole or in part on an accelerated basis, and some or all
of the shares of Common Stock subject to those terminated rights will immediately become vested shares, upon the occurrence of a Change in Control or another specified event or in the event that the Involuntary Termination of the Participant’s
Continuous Service occurs within a designated period of time following a specified event. 
 (iii) Restricted Stock Unit
Awards. 
 (1) Immediately following the consummation of any Change in Control, all outstanding Restricted Stock Unit Awards
will terminate, except to the extent they are assumed by the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction. 

(2) Each Restricted Stock Unit Award that is assumed or otherwise continued in effect in connection with a Change in Control will be
appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities which would have been issuable to the Participant in consummation of such Change in Control, had the Restricted Stock Unit Award been
settled immediately prior to such Change in Control. Appropriate adjustments will also be made to the number and class of securities available for issuance under the Plan following the consummation of such Change in Control. To the extent the
holders of Common Stock receive cash consideration in whole or part for their Common Stock in consummation of the Change in Control, the successor corporation may, in connection with the assumption of the outstanding Restricted Stock Unit Awards
under this Plan, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in such Change in Control transaction. 

(3) Among its discretionary powers, the Board will have the ability to structure a Restricted Stock Unit Award (either at the time the
Restricted Stock Unit Award is granted or at any time while the Restricted Stock Unit Award remains outstanding) so that some or all of the shares subject to that Restricted Stock Unit Award will automatically become vested shares upon the
occurrence of: (A) a Change in Control; (B) another specified event; and/or (C) the Involuntary Termination of the Participant’s Continuous Service within a designated period of time following a specified event. 

  
 19. 








 10. PLAN TERM; EARLIER TERMINATION
OR SUSPENSION OF THE PLAN. 
 (a) Plan Term. The Board
may suspend or terminate the Plan at any time. Unless terminated sooner by the Board, the Plan will 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. 

(b) No Impairment of Rights. Suspension or termination of the Plan will 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 or as otherwise permitted in the Plan. 
 11.
EFFECTIVE DATE OF PLAN. 
 This Plan will become effective on the Effective
Date. 
 12. CHOICE OF LAW. 

The laws of the State of Delaware will govern all questions concerning the construction, validity and interpretation of this Plan, without
regard to that state’s conflict of laws rules. 
 13. DEFINITIONS. As used in the Plan, the following definitions will apply to
the capitalized terms indicated below: 
 (a) “Affiliate” means, at the time of determination, any
“parent” or “majority-owned subsidiary” of the Company, as such terms are defined in Rule 405. The Board will have the authority to determine the time or times at which “parent” or “majority-owned
subsidiary” status is determined within the foregoing definition. 
 (b) “Board” means the Board of
Directors of the Company. 
 (c) “Capitalization Adjustment” means any change that is made in, or other
events that occur with respect to, the Common Stock subject to the Plan or subject to any Stock Award after the Effective Date without the receipt of consideration by the Company through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, stock split, reverse stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure, or any similar
equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto). Notwithstanding the foregoing, the conversion of any convertible
securities of the Company will not be treated as a Capitalization Adjustment. 
 (d) “Change in
Control” means a change in ownership or control of the Company effected through any of the following transactions: 

(i) a merger, consolidation or other reorganization unless securities representing more than 50% of the total combined voting power of
the voting securities of the successor corporation are immediately thereafter beneficially owned, directly or indirectly and in substantially the same proportion, by the persons who beneficially owned the Company’s outstanding voting securities
immediately prior to such transaction; 

  
 20. 








 (ii) a sale, transfer or other disposition of all or substantially all of the Company’s
assets; or 
 (iii) the acquisition, directly or indirectly, by any person or related group of persons (other than the Company or a person
that directly or indirectly controls, is controlled by, or is under common control with, the Company), of beneficial ownership (within the meaning of Rule 13-d3 of the Exchange Act) of securities possessing more than 50% of the total combined voting
power of the Company’s outstanding securities from a person or persons other than the Company. 
 In no event will any public offering
of the Company’s securities or the sale of newly issued capital stock or debt (including convertible debt) of the Company be deemed to constitute a Change in Control. 

(e) “Code” means the Internal Revenue Code of 1986, as amended, including any applicable regulations and
guidance thereunder. 
 (f) “Committee” means a committee of one or more Directors to whom authority has been
delegated by the Board in accordance with Section 2(c).

to render consulting or advisory services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for such services. However, service solely as a Director, or payment of a
fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the Plan.  
 (j)
“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, will not terminate a Participant’s Continuous Service; provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as
determined by the Board in its sole discretion, such Participant’s Continuous Service will 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 

  
 21. 








 
Consultant of an Affiliate or to a Director will 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 will 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 will 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. 

(k) “Director” means a member of the Board. 

(l) “Disability” means, with respect to a Participant, the inability of such Participant to engage in any
substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than
twelve (12) months as provided in Sections 22(e)(3) and 409A(a)(2)(c)(i) of the Code, and will be determined by the Board on the basis of such medical evidence as the Board deems warranted under the circumstances. 

(m) “Effective Date” means the effective date of this Plan, which is the earlier of (i) the date that this
Plan is first approved by the Company’s stockholders, and (ii) the date this Plan is adopted by the Board. 
 (n)
“Employee” means any person employed by the Company or an Affiliate. However, service solely as a Director, or payment of a fee for such services, will not cause a Director to be considered an “Employee” for
purposes of the Plan. 
 (o) “Entity” means a corporation, partnership, limited liability company or other
entity. 
 (p) “Exchange Act” means the Securities Exchange Act of 1934, as amended, and the rules and

fifty percent (50%) of the combined voting power of the Company’s then outstanding securities. 

  
 22. 








 (r) “Fair Market Value” means, as of any date, the value of the
Common Stock determined by the Board in compliance with Section 409A of the Code or, in the case of an Incentive Stock Option, in compliance with Section 422 of the Code. 

(s) “Incentive Stock Option” means an option granted pursuant to Section 5 of the Plan that is intended to
be, and that qualifies as, an “incentive stock option” within the meaning of Section 422 of the Code. 
 (t)
“Involuntary Termination” means (i) a Participant’s involuntary dismissal or discharge by the Company (or any Parent or Subsidiary) for reasons other than Misconduct, or (ii) a Participant’s
voluntary resignation within 60 days following: (A) a change in his or her position with the Company (or any Parent or Subsidiary) which materially reduces his or her duties and responsibilities; (B) a reduction in his or her base salary
by more than 15%, unless the base salaries of all similarly situated individuals are reduced by the Company or any Parent or Subsidiary employing the individual; or (c) a relocation of the Participant’s place of employment by more than
fifty miles, provided and only if such change, reduction or relocation is effected without the Participant’s written consent. 

(u) “Misconduct” will 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: (i) the commission of any act of fraud, embezzlement or dishonesty by the Participant, (ii) any unauthorized use or
disclosure by such person of confidential information or trade secrets of the Company or any Affiliate, or (iii) any other intentional misconduct by such person adversely affecting the business or affairs of the Company or any Affiliate in a
material manner. The foregoing definition will not in any way preclude or restrict the right of the Company or any Affiliate to discharge or dismiss the Participant for any other acts or omissions, but such other acts or omissions will not be
deemed, for the purposes of the Plan, to constitute grounds for termination for Misconduct. 
 (v) “Nonstatutory Stock
Option” means any option granted pursuant to Section 5 of the Plan that does not qualify as an Incentive Stock Option. 

(w) “Officer” means any person designated by the Company as an officer. 

(x) “Option” means an Incentive Stock Option or a Nonstatutory Stock Option to purchase shares of Common Stock
granted pursuant to the Plan. 
 (y) “Option Agreement” means a written agreement between the Company and an
Optionholder evidencing the terms and conditions of an Option grant. Each Option Agreement will be subject to the terms and conditions of the Plan. 

(z) “Optionholder” means a person to whom an Option is granted pursuant to the Plan or, if applicable, such
other person who holds an outstanding Option.

part by reference to the Common Stock which is granted pursuant to the terms and conditions of Section 6(c).
