	1.	GENERAL. 

 (a)    Eligible Stock Award
Recipients. Employees, Directors and Consultants are eligible to receive Stock Awards. 
 (b)    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. 
 (c)    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 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). 
  

  
 1. 








 (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 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, (1) a Participant’s rights will not be deemed to have been impaired by any such amendment if the Board, in its sole discretion, determines that the amendment, taken as a whole, does not
materially impair the Participant’s rights, and (2) 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 change the terms of an Incentive Stock Option, if such change results in impairment of the Award solely because it impairs the
qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (C) to clarify the manner of exemption from, or to bring the Stock Award into compliance with, Section 409A of the Code; or (D) 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). 
  

  
 2. 








 (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 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(t) 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 1,659,157 shares (the “Share Reserve”). 

  
 3. 








 (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). 

(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 a number of shares of Common Stock equal to three (3) multiplied by the Share
Reserve. 
 (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. 

(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. 

  
 4. 









	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 Corporate Transaction 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; 
 (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; 

  
 5. 








 (v)    according to a deferred payment or similar arrangement with the
Optionholder; provided, however, that interest will compound at least annually and will 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 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 strike price. 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. 

(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, 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. 

  
 6. 








 (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, if a Participant’s Continuous Service terminates (other than for Cause 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 Cause) 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. 

(h)    Extension of Termination Date. Except as otherwise provided in the applicable Stock Award Agreement
or other agreement between the Participant and the Company, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause 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 three (3) months (that need not be consecutive) 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 Cause) 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. 


  
 7. 








 (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 designated to exercise the Option or SAR
upon the Participant’s death, but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Stock Award Agreement, which
period 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 Cause. Except as explicitly provided otherwise in a Participant’s Stock
Award Agreement or other individual written agreement between the Company or any Affiliate and the Participant, if a Participant’s Continuous Service is terminated for Cause, 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 Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or
(iv) 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 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. 

  
 8. 








 (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 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. 
 (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. 

  
 9. 








 (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. 

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

  
 10. 








 (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. 

(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. 

  
 11. 








 (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 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)    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. 

  
 12. 








 (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 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 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. 

(l)    Compliance with Exemption Provided by Rule 12h-1(f). If at
the end of the Company’s most recently completed fiscal year: (i) the aggregate of the number of persons who hold outstanding compensatory employee stock options to purchase shares of Common Stock granted pursuant to the Plan or otherwise
(such persons, “Holders of Options”) equals or exceeds five hundred (500), and (ii) the Company’s assets exceed $10 million, then the following restrictions will 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 to
be issued on 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 Holder of Options, or (3) to an
executor upon the death of the Holder of Options (collectively, the “Permitted Transferees”); provided, however, the following transfers are permitted: (i) transfers by Holders of Options 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 

  
 13. 








 
Transferees may not further transfer the Options; (B) except as otherwise provided in (A) above, the Options and shares of Common Stock issuable on 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 Holders of Options prior to exercise of an Option until the Company is no longer relying on the exemption
provided by Rule 12h-1(f); and (C) at any time that the Company is relying on the exemption provided by Rule 12h-1(f), the Company will deliver to Holders of
Options (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 Holder of Options’ agreement to maintain
its confidentiality. 
 (m)    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 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 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)    Corporate Transaction. The following provisions will 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 Participant or unless otherwise expressly provided by
the Board at the time of grant of a Stock Award. In the event of a Corporate Transaction, then, notwithstanding any other provision of the Plan, the Board may 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); 

  
 14. 








 (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 determines (or, if the Board does 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; provided, however, that the Board may require Participants to complete and deliver to the
Company a notice of exercise before the effective date of a Corporate Transaction, which exercise is contingent upon the effectiveness of such Corporate Transaction; 

(iv)    arrange for the lapse, in whole or in part, 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 Participant would have received upon the exercise of the Stock Award immediately prior to the effective time of the Corporate Transaction, over (B) any exercise price payable by such holder in connection with such
exercise. For clarity, this payment may be zero ($0) if the value of the property is equal to or less than the exercise price. Payments under this provision may be delayed to the same extent that payment of consideration to the holders of the
Company’s Common Stock in connection with the Corporate Transaction is delayed as a result of escrows, earn outs, holdbacks or any other contingencies. 

The Board need not take the same action or actions with respect to all Stock Awards or portions thereof or with respect to all Participants. The Board may
take different actions with respect to the vested and unvested portions of a Stock Award.  

(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 will occur. 
  

	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. 

  
 15. 








 (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)    “Cause” 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, 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
will 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 Stock Awards held by such Participant will have
no effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose. 

  
 16. 








 (e)     “Change in Control” means the
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 will
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 will 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; 
 (iii)     the stockholders of the Company approve or the Board
approves a plan of complete dissolution or liquidation of the Company, or a complete dissolution or liquidation of the Company will otherwise occur, except for a liquidation into a parent corporation;  

(iv)    there is consummated a sale, lease, exclusive license or other 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 
 (v)    individuals who, on the date
the Plan is adopted by the 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 will, 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 will 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 will 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 such an individual written agreement, the foregoing definition will apply. 

  
 17. 








 (f)    “Code” means the Internal Revenue Code
of 1986, as amended, including any applicable regulations and guidance thereunder. 

(g)    “Committee” means a committee of one or more Directors to whom authority has been
delegated by the Board in accordance with Section 2(c). 
 (h)     “Common Stock”
means the common stock of the Company. 
 (i)    “Company” means nToggle, Inc., a
Delaware corporation. 
 (j)    “Consultant” means any person, including an advisor, who
is (i) engaged by the Company or an Affiliate 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.  

(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, 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 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. 
 (l)    “Corporate Transaction” means the consummation,
in a single transaction or in a series of related transactions, of any one or more of the following events: 

(i)    a sale or other disposition of all or substantially all, as determined by the Board in its sole
discretion, of the consolidated assets of the Company and its Subsidiaries; 
 (ii)    a sale or other
disposition of at least ninety percent (90%) of the outstanding securities of the Company; 

(iii)    a merger, consolidation or similar transaction following which the Company is not the surviving
corporation; or 

  
 18. 








 (iv)    a merger, consolidation or similar transaction following which
the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into
other property, whether in the form of securities, cash or otherwise. 

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

(n)    “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. 

(o)    “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. 

(p)    “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. 

(q)    “Entity” means a corporation, partnership, limited liability company or other
entity. 
 (r)    “Exchange Act” means the Securities Exchange Act of 1934, as amended,
and the rules and regulations promulgated thereunder. 
 (s)    “Exchange Act
Person” means any natural person, Entity or “group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act), except that “Exchange Act Person” will not include (i) the

 RESTRICTED STOCK GRANT NOTICE 







 ATTACHMENT I 

NTOGGLE, INC. 

2014 EQUITY INCENTIVE PLAN 

RESTRICTED STOCK AGREEMENT 

Pursuant to the Restricted Stock Grant Notice (“Grant Notice”), this Restricted Stock Agreement
(“Agreement”), and its 2014 Equity Incentive Plan (“Plan”), NTOGGLE, INC. (“Company”) has issued to you, in exchange for your past or future
services actually or to be rendered to the Company, the number of Shares of Common Stock indicated in the Grant Notice (“Shares”). Capitalized terms not explicitly defined in this Agreement but defined in the Plan or the
Grant Notice will have the same definitions as in the Plan or the Grant Notice. If there is any conflict between the terms in this Agreement and the Plan, the terms of the Plan will control, unless otherwise specifically provided. 

The details of your award, in addition to those set forth in the Grant Notice and the Plan, are as follows: 

1. VESTING. 

a. Subject to the limitations contained in this Agreement, the Shares will vest pursuant to the Vesting Schedule in the Grant Notice,
provided that vesting will cease upon the termination of your Continuous Service. 
 b. For purposes hereof, “Good
Reason” shall mean any of the following actions taken by the Company or a successor corporation or entity without your consent (unless such action is taken in response to conduct by you that constitutes Cause: (1) material
reduction of your base compensation, other than a reduction that applies generally to all executives and does not exceed 10%; (2) material reduction in your authority, duties or responsibilities, provided, however, that a change in job position
(including a change in title) shall not be deemed a “material reduction” unless your new authority, duties or responsibilities are materially reduced from the prior authority, duties or responsibilities; (3) failure or refusal of a
successor to the Company to materially assume the Company’s obligations under this Agreement in the event of a Change in Control; or (4) relocation of your principal place of employment that results in an increase in your one-way driving distance by more than 50 miles from your then current principal residence. In order to resign for Good Reason, you must provide written notice of the event giving rise to Good Reason to the
Company’s Board of Directors within 90 days after the condition arises, allow the Company 30 days to cure such condition, and if the Company fails to cure the condition within such period, your resignation from all positions that you then hold
with the Company must be effective not later than 90 days after the end of the Company’s cure period. “Vested Shares” will mean Shares that have vested in accordance with the Vesting Schedule set forth on the Grant
Notice (the “Vesting Schedule”) or this Section 1, and “Unvested Shares” will mean Shares that have not vested in accordance with the Vesting Schedule or this Section 1. 

c. If any payment or benefit you would receive pursuant to a Change in Control from the Company or otherwise
(“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code (as defined in the Plan), and (ii) but for this sentence, be subject to the excise tax imposed by
Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that would
result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes,
income taxes, and the Excise Tax (all computed at the highest 

  
 1. 








 
applicable marginal rate), results in your receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of
the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order unless you
elect in writing a different order (provided, however, that such election shall be subject to Company approval if made on or after the effective date of the event that triggers the Payment): reduction of cash payments; cancellation of accelerated
vesting of Stock Awards (as defined in the Plan); reduction of employee benefits. In the event that acceleration of vesting of Stock Award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the
date of grant of your Stock Awards (i.e., earliest granted Stock Award cancelled last) unless you elect in writing a different order for cancellation. The accounting firm engaged by the Company for general audit purposes as of the day prior to the
effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company
shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. The accounting firm
engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to you and the Company within fifteen (15) calendar days after the date on which your right to a Payment is triggered
(if requested at that time by you or the Company) or such other time as requested by you or the Company. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced
Amount, it shall furnish you and the Company with an opinion reasonably acceptable to you that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding
and conclusive upon you and the Company. 
 2. NUMBER OF
SHARES. The number of Shares subject to this award may be adjusted from time to time for Capitalization Adjustments. In the event of any such Capitalization Adjustments, any additional Shares of Common
Stock that you receive will be subject to the same vesting requirements and vesting schedule that is applicable to the Shares with respect to which such additional Shares relate. 

3. SECURITIES LAW COMPLIANCE. The Shares are not
registered under the Securities Act. At this time, the Company has determined that the issuance of the Shares under this Agreement is exempt from the registration requirements of the Securities Act. If the Company determines at any time that an
exemption from the registration requirements of the Securities Act was not available or that the issuance of the Shares otherwise would not comply with any other applicable laws and regulations, then the Company will not be obligated to issue the
Shares or may rescind the award to you. 
 4. REACQUISITION OR REPURCHASE
RIGHT. 
 a. Reacquisition Right. In the event that your Continuous Service terminates, the Company
will automatically reacquire (the “Reacquisition Right”) (i) any Unvested Shares (after giving effect to any accelerated vesting provided for under the Vesting Schedule or Section 1 above), and (ii) any Vested
Shares, if the Company has terminated your Continuous Service for Cause (as defined in the plan), in either case, without any payment to you (that is, for zero dollars ($0)) and without any required action or notice to you. This Reacquisition Right
as to Vested Shares for no consideration is specifically intended to supersede any repurchase limitations that may be contained the Plan (which otherwise may provide that vested shares can only be repurchased for no less than fair market value). You
hereby agree to take whatever action the Company determines necessary to effectuate the Company’s reacquisition of the Shares. Following the reacquisition, the Company will become the legal and beneficial owner of the Shares being reacquired
and all rights and interests in and related to such Shares, and the Company will have the right to transfer to its own name the Shares being reacquired by the Company without further 

  
 2. 








 
action by you. Notwithstanding anything to the contrary in this Section 4(a) or in this Agreement, the Company may elect to waive, in its sole discretion, its Reacquisition Right in whole or
in part by providing written notice to you (with a copy to the Escrow Agent, as defined in Section 7), at any time, and the Escrow Agent may then release to you the number of Shares of Common Stock subject to escrow that are not being
reacquired by the Company. 
 b. Repurchase Right. In the event that your Continuous Service is terminated by the Company for a
reason other than Cause, or you terminate your Continuous Service for any reason, then the Company may elect (but is not obligated) to repurchase all or any part of the Vested Shares after taking into account the forfeiture clause above (the
Company’s “Vested Share Repurchase Right”), subject to the following provisions: 
 1) The
Company’s Vested Share Repurchase Right will be exercisable only within the 90 day period following the termination of your Continuous Service, or such longer period as may be agreed to by the Company and you (the “Repurchase
Period”), by a written notice delivered to you by the Company. 
 2) The Company may exercise its Vested Share
Repurchase Right for less than all of the Vested Shares. 
 3) The repurchase price for Vested Shares will be equal to the
Shares’ Fair Market Value on the date of repurchase (“Repurchase Price”). 
 4) The Company may
exercise its Vested Share Repurchase Right for cash, a promissory note, or a combination of both. The Company will pay the Repurchase Price (in the form of cash or a promissory note, or both) on the last day of the Repurchase Period. 

The Company’s Vested Share Repurchase Right will 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 (“IPO Date”). 
 c.
Corporate Transactions. In the event of a Corporate Transaction, the Company may provide that the Reacquisition Right may be assigned by the Company to the surviving or acquiring corporation (or the surviving or acquiring corporation’s
parent company), if any, in connection with the Corporate Transaction or that its Reacquisition Right may lapse in connection with the Corporate Transaction. To the extent the Reacquisition Right remains in effect following a Corporate Transaction,
it will apply to the new capital stock, cash or other property received in exchange for the Shares in consummation of the Corporate Transaction. 

d. Termination of Reacquisition Right. The Reacquisition Right will terminate upon the Company’s reacquisition or repurchase in
full of the Shares (or waiver of the Reacquisition Right as to all of the Shares). 
 5. TRANSFER
RESTRICTIONS. You are not permitted and agree that you will not sell, assign, hypothecate, donate, encumber or otherwise dispose of all or any part of the Unvested Shares or any interest in the
Unvested Shares while such Shares are subject to the Reacquisition Right; provided, however, that an interest in the Unvested Shares may be transferred pursuant to a qualified domestic relations order as defined in the Code or Title I of the
Employee Retirement Income Security Act of 1974. In the case of Vested Shares, you will not sell, assign, hypothecate, donate, encumber or otherwise dispose of all or any part of the Vested Shares or any interest in the Vested Shares except in
compliance with this Agreement (including, without limitation, Section 6), the Company’s bylaws, any shareholders’ 

  
 3. 








 
agreement that you may be required to execute, and applicable securities laws. For clarity, no sale, transfer or other disposition of the Vested Shares or any interest in the Vested Shares may
occur unless the Company has first determined that such sale, transfer or other disposition is permitted by applicable securities laws (even if otherwise allowed by this Agreement and the Company’s corporate governance documents). 

6. RIGHT OF FIRST REFUSAL. The
Company shall have a right of first refusal, as described below, with respect to any voluntary or involuntary sale, assignment, gift, donation, pledge, or other disposition (each a “Transfer”) of Vested Shares by you,
provided, however, that no such right of first refusal shall exist in the case of a sale, transfer of other disposition by you of Vested Shares to a third-party in connection with a Change in Control transaction.
In addition, the term Transfer does not include a transfer of Vested Shares for no consideration to your Immediate Family (as defined below), provided that such Immediate Family Member agrees in writing to hold the Vested Shares so transferred
subject to the provisions of this Agreement (including, without limitation, this Section 6), and that there will be no further transfer of such Vested Shares except in accordance with the terms of this Section 6. As used herein, the term
“Immediate Family” will mean your spouse (or domestic partner), the lineal descendant or antecedent, father, mother, brother or sister, child, adopted child, grandchild or adopted grandchild of you or your spouse (or domestic
partner), or the spouse (or domestic partner) of any child, adopted child, grandchild or adopted grandchild of you or your spouse (or domestic partner). If you desire or are required to Transfer some or all of the Vested Shares during your lifetime,
you must, before effecting any such Transfer (and to the extent otherwise not precluded by any court or tribunal) offer to sell the Vested Shares proposed for Transfer (the “Offered Shares”) to the Company by means of a
written notice (the “Offer Notice”) to the Company stating (A) the number of Offered Shares, (B) the name and address of the third party to whom the Offered Shares will be Transferred, and (C) the purchase
price and terms of payment for the Offered Shares determined in accordance with the following two sentences. If the proposed Transfer is in a sale in which you will receive something of value for the Offered Shares, the purchase price and terms of
payment will be as set forth in a bona-fide offer from a third party to purchase the Offered Shares, but in no event will the Company be required to pay you an amount for the Offered Shares that is in excess of the Fair Market Value of the Offered
Shares on the date the Company gives written notice to you electing to exercise its Purchase Right (as defined below) as determined in good faith by the Board. If the proposed Transfer is other than in a sale in which you will not receive something
of value for the Offered Shares (such as in an involuntary Transfer, or a gift, donation, or pledge), you shall state in the Offer Notice that no purchase price and terms of payment are being proposed and that the purchase price and terms of payment
will be Fair Market Value of the Offered Shares on the date the Company gives written notice to you electing to exercise its Purchase Right as determined in good faith by the Board. For 30 days after the Company’s receipt of the Offer Notice
under this Section (the “Option Period”), the Company will have the right (but not the obligation) to purchase all or any portion of the Offered Shares (such right, the “Purchase Right”). The Company
may exercise the Purchase Right by giving written notice to you (or your legal representative) during the Option Period specifying the number of Offered Shares it is electing to purchase. The Company may assign its Purchase Right hereunder in the
discretion of the Board and such rights will be cumulative in the event more than one event occurs giving rise to a right. The purchase price with respect to any purchase pursuant to the Purchase Right shall be paid to you in cash by no later than
the end of the Option Period (or if the Offer Notice contains terms of payment that provide for payments to be made to you on dates occurring after the Option Period, then the Company may make its payments on those same dates). In the event of a
Change in Control, all payments hereunder shall be accelerated to the date of the Change in Control and shall be due and payable at that time. Notwithstanding the above, the Company’s Purchase Right will expire at 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. Any recipient or transferee of the Offered Shares from you under this Section 6 may not subsequently
Transfer or otherwise dispose of the Offered Shares unless permitted by the Company in its sole discretion. Any such recipient or 

  
 4. 








 
transferee will become subject to the terms of this Agreement on the same basis as you. As a condition to your transfer of any Offered Shares, the recipient or transferee must acknowledge their
obligation to abide by the terms of this Agreement and must execute this Agreement or any other agreements required to be executed by shareholders of the Company as requested by the Company. 

7. ESCROW OF SHARES. As security for
your faithful performance of the terms of this Agreement and to ensure the availability for delivery of the Shares upon exercise of the Reacquisition Right, you agree that the Shares issued to you will be held in escrow pursuant to the terms of the
Joint Escrow Instructions attached to the Grant Notice as ATTACHMENT IV. You agree to execute and deliver to the Secretary of the Company or the Secretary’s designee (the “Escrow Agent”), two
(2) Assignment Separate From Certificate forms (with date and number of shares blank) substantially in the form attached to the Grant Notice as ATTACHMENT III and deliver the same, along with the certificate or
certificates evidencing the shares, for use by the Escrow Agent pursuant to the terms of the Joint Escrow Instructions. 
 8.
RIGHTS AS STOCKHOLDER. Subject to the terms of this Agreement, you will exercise all rights and privileges of a stockholder of the Company with respect to the
Shares of Common Stock deposited in escrow. You will be deemed to be the holder of the Shares for purposes of receiving any dividends that may be paid with respect to such Shares (which will be subject to the same vesting and forfeiture restrictions
as apply to the Shares to which they relate) 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 Reacquisition Right. 

9. RESTRICTIVE LEGENDS. All certificates representing the Common Stock issued under this
Agreement will be endorsed with legends in substantially the following forms (in addition to any other legend that may be required by other agreements between you and the Company): 

a. “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A REACQUISITION RIGHT, REPURCHASE RIGHT AND OTHER RESTRICTIONS AND
CONDITIONS SET FORTH IN A RESTRICTED STOCK AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE COMPANY’S PRINCIPAL CORPORATE OFFICES. ANY TRANSFER OR
ATTEMPTED TRANSFER OF ANY SHARES SUBJECT TO SUCH RIGHT IS VOID WITHOUT THE PRIOR EXPRESS WRITTEN CONSENT OF THE COMPANY.” 
 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 CERTAIN RIGHTS OF REFUSAL GRANTED TO THE COMPANY AND ACCORDINGLY MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, ENCUMBERED OR IN ANY MANNER DISPOSED OF EXCEPT IN CONFORMITY WITH THE TERMS
OF THE BYLAWS OF THE COMPANY AND/OR A RESTRICTED STOCK AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE COMPANY’S PRINCIPAL CORPORATE OFFICES.” 

d. Any legend required by appropriate blue sky officials. 

  
 5. 








 10. AWARD NOT A SERVICE
CONTRACT. Your receipt of the Shares is not an employment or service contract, and nothing in this Agreement will 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 on the part of the Company or an Affiliate to continue your employment. In addition, nothing in your Award will 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. 

11. WITHHOLDING OBLIGATIONS. 

a. At the time you are issued any Shares, 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 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 issuance or vesting of your Shares (including the filing of a Section 83(b) Election as provided in Section 14 of this Agreement) (the “Withholding Taxes”). The Company may, in its sole
discretion, satisfy all or any portion of the Withholding Taxes obligation relating to the issuance or vesting of the Shares (or the filing of a Section 83(b) Election) by any of the following means or by a combination of such means:
(i) withholding from any amounts otherwise payable to you by the Company; (ii) causing you to tender a cash payment; or (iii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to you with
a Fair Market Value equal to the amount of such Withholding Taxes; provided, however, that the number of such shares of Common Stock withheld may not exceed the amount necessary to satisfy the Company’s required tax withholding
obligations using the minimum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income. 

b. Unless the tax withholding obligations of the Company and any Affiliate are satisfied, the Company will have no obligation to issue
a certificate for such Shares or release such Shares from any escrow provided for in this Agreement. 
 12.
INVESTMENT REPRESENTATIONS. In connection with your acquisition of the Common Stock under this Agreement, you represent to the Company the following: 

a. You are aware of the Company’s business affairs and financial condition and have acquired sufficient information about the
Company to reach an informed and knowledgeable decision to acquire the Common Stock. You are acquiring the Common Stock for investment for your 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. You understand 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 your investment intent as expressed in this Agreement. 

c. You further acknowledge and understand 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. You further acknowledge and understand that the Company is under no obligation to register the Common Stock. You understand 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. 

  
 6. 








 d. You are 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 Exchange Act, the securities exempt under Rule 701 may be sold by you ninety (90) days
thereafter, subject to the satisfaction of certain of the conditions specified by Rule 144 and the market stand-off agreement described in Section 13. 

e. In the event that the sale of the Common Stock does not qualify under Rule 701 at the time of issuance, then the Common Stock
may be resold by you 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 you have purchased, and made full payment of (within the meaning of Rule 144), the securities to be sold. 

f. You further understand that at the time you wish 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, you would be precluded from selling the Common Stock under
Rule 144 or 701 even if the minimum holding period requirement had been satisfied. 
 13. MARKET
STAND-OFF AGREEMENT. By acquiring shares of Common Stock under this Agreement, you agree that you will 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 with respect to 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 the underwriters or the Company will request to facilitate compliance with FINRA Rule 2711 or NYSE
Member Rule 472 or any successor or similar rules or regulation (the “Lock-Up Period”); provided, however, that nothing contained in this Section 13 will 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 or the
underwriters 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. You also agree that any transferee of any shares of Common Stock (or other securities) of the Company held by you will be bound by this Section 13. The underwriters of the Company’s stock are intended third party
beneficiaries of this Section 13 and will have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 

14. TAX CONSEQUENCES. You agree to review with your own tax advisors the federal, state, local and
foreign tax consequences of this investment and the transactions contemplated by this Agreement. You will rely solely on your advisors and not on any statements or representations of the Company or any of its agents. You understand that you (and not
the Company) will be responsible for your own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. You understand that Section 83 of the Code taxes as ordinary income to you the fair
market value of the Shares of Common Stock issued to you under this Agreement as of the date any restrictions on the Shares lapse (that is, as of the date on which part or all of the Shares vest). In this context, “restriction” includes
the right of the Company to reacquire the Common Stock pursuant to its Reacquisition Right set forth above. You understand that you may elect to be taxed at the time the 

  
 7. 








 
Common Stock is issued to you pursuant to this Agreement, rather than when and as the Reacquisition Right expires, by filing an election under Section 83(b) of the Code (an “83(b)
Election”) with the Internal Revenue Service within 30 days after the date you acquire Shares of Common Stock pursuant to this Agreement. A sample 83(b) Election is attached as Attachment V for convenience. Even if the fair market value
of the Common Stock at the time it is issued 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. You understand that failure to file an 83(b) Election in a timely
manner may result in adverse tax consequences for you. You further understand that you must file an additional copy of the 83(b) Election with your federal income tax return for the calendar year in which you make the 83(b) Election. You acknowledge
that the foregoing is only a summary of the effect of U.S. federal income taxation with respect to issuance of the Common Stock pursuant to this Agreement, and does not purport to be complete. You further acknowledge that notwithstanding the
inclusion of a sample 83(b) Election as Attachment V, the Company has directed you to seek independent advice regarding the applicable provisions of the Code, the income tax laws of any municipality, state or foreign country in which you may reside,
and the tax consequences of your death. You assume all responsibility for filing an 83(b) Election and paying all taxes resulting from the 83(b) Election or the lapse of the restrictions on the Common Stock. YOU ACKNOWLEDGE THAT NOTWITHSTANDING THE
INCLUSION OF A SAMPLE 83(B) ELECTION AS ATTACHMENT V, IT IS YOUR OWN RESPONSIBILITY, AND NOT THE COMPANY’S, TO FILE A TIMELY 83(B) ELECTION. THE COMPANY AND ITS LEGAL COUNSEL CANNOT ASSUME RESPONSIBILITY FOR FAILURE TO FILE THE 83(B) ELECTION
IN A TIMELY MANNER UNDER ANY CIRCUMSTANCES. 
 15. NOTICES. Any notices provided
for in this Agreement or the Plan will be given in writing and will be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five days after deposit in the U.S. mail, postage prepaid, addressed to you at
the last address you provided to the Company. 
 16. MISCELLANEOUS. 

a. As a condition to the Company’s issuance of any Shares of Common Stock under this Agreement, the Company may require you
to execute certain customary agreements entered into with the holders of capital stock of the Company, including without limitation a right of first refusal and co-sale agreement, stockholders agreement and a
voting agreement. 
 b. The rights and obligations of the Company under this Agreement will be transferable by the Company to any one
or more persons or entities, and all covenants and agreements hereunder will inure to the benefit of, and be enforceable by the Company’s successors and assigns. Your rights and obligations under this Agreement may only be assigned with the
prior written consent of the Company. 
 c. You agree upon request to execute any further documents or instruments necessary or
desirable in the sole determination of the Company to carry out the purposes or intent of this Agreement. 
 d. You acknowledge and
agree that you have reviewed this Agreement in its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting the Shares and fully understand all provisions of this Agreement. 

17. GOVERNING PLAN DOCUMENT. This Agreement and the
Shares issued to you hereunder are subject to all the terms of the Plan, the terms of which are hereby made a part of this Agreement, 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 this Agreement and those of the Plan, the provisions of the Plan will control. 

  
 8. 








 18. CAPITALIZATION
ADJUSTMENTS. In the event of a Capitalization Adjustment, then any and all new, substituted or additional securities or other property to which you are entitled by reason of your ownership of the
Shares will be immediately subject to the Reacquisition Right, the Vested Share Repurchase Right, the restrictions on transfer set forth in Section 5 of this Agreement and the Purchase Right set forth in Section 6 of this Agreement with
the same force and effect as the Shares subject to the those rights, restrictions and limitations immediately before such event.

This Restricted Stock Agreement will be deemed to be signed by the Company and Participant upon the signing by Participant of the Restricted
Stock Grant Notice to which it is attached.
