 3. Stock Subject to the Plan. 

(a) Stock Subject to the Plan. Subject to the provisions of Section 13 of the Plan, the maximum aggregate number of Shares
that may be issued under the Plan is 8,000,000 Shares, plus (i) any Shares that, as of the Registration Date, have been reserved but not issued pursuant to any awards granted under the Company’s 2005 Stock Plan (the “Existing
Plan”) and are not subject to any awards granted thereunder, and (ii) any Shares subject to stock options or similar awards granted under the Existing Plan that expire or otherwise terminate without having been exercised in full and
Shares issued pursuant to awards granted under the Existing Plan that are forfeited to or repurchased by the Company. The Shares may be authorized, but unissued, or reacquired Common Stock. 

(b) Lapsed Awards. If an Award expires or becomes unexercisable without having been exercised in full, is surrendered pursuant to
an Exchange Program, or, with respect to Restricted Stock, Restricted Stock Units, Performance Units or Performance Shares, is forfeited to or repurchased by the Company due to failure to vest, the unpurchased Shares (or for Awards other than
Options or Stock Appreciation Rights the forfeited or repurchased Shares) which were subject thereto will become available for future grant or sale under the Plan (unless the Plan has terminated). With respect to Stock Appreciation Rights, only
Shares actually issued pursuant to a Stock Appreciation Right will cease to be available under the Plan; all remaining Shares under Stock Appreciation Rights will remain available for future grant or sale under the Plan (unless the Plan has
terminated). Shares that have actually been issued under the Plan under any Award will not be returned to the Plan and will not become available for future distribution under the Plan; provided, however, that if Shares issued pursuant to Awards of
Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares will become available for future grant under the Plan. Shares used to pay the exercise
price of an Award or to satisfy the tax withholding obligations related to an Award will become available for future grant or sale under the Plan. To the extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will
not result in reducing the number of Shares available for issuance under the Plan. Notwithstanding the foregoing and, subject to adjustment as provided in Section 13, the maximum number of Shares that may be issued upon the exercise of
Incentive Stock Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 of the Code and the Treasury Regulations promulgated thereunder, any Shares that become available for
issuance under the Plan pursuant to Sections 3(b). 
 (c) Share Reserve. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan.

 4. Administration of the Plan. 

(a) Procedure. 

(i) Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the
Plan. 
 (ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards
granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan will be administered by a Committee of two (2) or more “outside directors” within the meaning of
Section 162(m) of the Code. 
 (iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as
exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3. 

(iv) Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a
Committee, which committee will be constituted to satisfy Applicable Laws. 
 (b) Powers of the Administrator. Subject to
the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion: 

(i) to determine the Fair Market Value; 

(ii) to select the Service Providers to whom Awards may be granted hereunder; 

(iii) to determine the number of Shares to be covered by each Award granted hereunder; 

(iv) to approve forms of Award Agreements for use under the Plan;

conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine;

 (viii) to construe and interpret the terms of the Plan and Awards granted pursuant to the
Plan; 
 (ix) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations
relating to sub-plans established for the purpose of satisfying applicable foreign laws; 
 (x) to modify or amend each Award
(subject to Section 18(c) of the Plan), including but not limited to the discretionary authority to extend the post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(b) regarding
Incentive Stock Options); 
 (xi) to allow Participants to satisfy withholding tax obligations in such manner as prescribed in
Section 14; 
 (xii) to authorize any person to execute on behalf of the Company any instrument required to effect the
grant of an Award previously granted by the Administrator; 
 (xiii) to allow a Participant to defer the receipt of the payment
of cash or the delivery of Shares that would otherwise be due to such Participant under an Award; and 
 (xiv) to make all
other determinations deemed necessary or advisable for administering the Plan. 
 (c) Effect of Administrator’s
Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards. 

5. Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance
Shares and Performance Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 

6. Stock Options. 

(a) Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options will be taken into
account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. 

(b) Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the
term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is

  

 -7- 

 
granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive
Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 

(c) Option Exercise Price and Consideration. 

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined
by the Administrator, subject to the following: 
 (1) In the case of an Incentive Stock Option 

a) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant.

 b) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise
price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (2) In
the case of a Nonstatutory Stock Option, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(3) Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than one hundred percent
(100%) of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code. 

(ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the
Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised. 
 (iii)
Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable
form of consideration at the time of grant. Such consideration may consist entirely of: (1) cash; (2) check; (3) promissory note, (4) other Shares, provided that such Shares have a Fair Market Value on the date of surrender equal
to the aggregate exercise price of the Shares as to which such Option will be exercised and provided that accepting such Shares, in the sole discretion of the Administrator, will not result in any adverse accounting consequences to the Company;
(5) consideration received by the Company under a broker-assisted (or other) cashless exercise program implemented by the Company in connection with the Plan; (6) any combination of the foregoing methods of payment; or (7) such other
consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws. 
  

 -8- 

 (d) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of
the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed exercised when the Company receives: (i) notice of exercise (in such form as the Administrator may specify
from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any consideration
and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the
Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a
stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a
dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale
under the Option, by the number of Shares as to which the Option is exercised. 
 (ii) Termination of Relationship as a
Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within such period
of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a
specified time in the Award Agreement, the Option will remain exercisable for three (3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not
vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the
Option will terminate, and the Shares covered by such Option will revert to the Plan. 
 (iii) Disability of
Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the
Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for
twelve (12) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

  

 -9- 

 (iv) Death of Participant. If a Participant dies while a Service Provider, the
Option may be exercised following the Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the option be exercised later than the
expiration of the term of such Option as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator.
If no such beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s
will or in accordance with the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided
by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time
specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 
 7. Restricted
Stock. 
 (a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any
time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 

(b) Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the
Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of
Restricted Stock until the restrictions on such Shares have lapsed. 
 (c) Transferability. Except as provided in this
Section 7, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction. 

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted
Stock as it may deem advisable or appropriate. 
 (e) Removal of Restrictions. Except as otherwise provided in this
Section 7, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may
determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 

(f) Voting Rights. During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may
exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 
  

 -10- 

 (g) Dividends and Other Distributions. During the Period of Restriction, Service
Providers holding Shares of Restricted Stock will be entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends or distributions are paid in Shares,
the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid. 

(h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which
restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan. 
 8.
Restricted Stock Units. 
 (a) Grant. Restricted Stock Units may be granted at any time and from time to time as
determined by the Administrator. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant,
including the number of Restricted Stock Units. 
 (b) Vesting Criteria and Other Terms. The Administrator will set
vesting criteria in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the
achievement of Company-wide, business unit, or individual goals (including, but not limited to, continued employment), or any other basis determined by the Administrator in its discretion. 

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be entitled to receive a
payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a
payout. 
 (d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made as soon as practicable
after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or a combination of both. 

(e) Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units will be forfeited to the
Company. 
 9. Stock Appreciation Rights.

to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. 

(b) Number of Shares. The Administrator will have complete discretion to determine the number of Stock Appreciation Rights granted
to any Service Provider. 
  

 -11- 

 (c) Exercise Price and Other Terms. The per share exercise price for the Shares to be
issued pursuant to exercise of a Stock Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, subject to
Section 6(a) of the Plan, the Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan. 

(d) Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will
specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 

(e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the Plan will expire upon the date
determined by the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(d) also will apply to Stock Appreciation Rights. 

(f) Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to
receive payment from the Company in an amount determined by multiplying: 
 (i) The difference between the Fair Market Value of
a Share on the date of exercise over the exercise price; times 
 (ii) The number of Shares with respect to which the Stock
Appreciation Right is exercised. 
 At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise
may be in cash, in Shares of equivalent value, or in some combination thereof. 
 10. Performance Units and Performance
Shares. 
 (a) Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service
Providers at any time and from time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to each
Participant. 
 (b) Value of Performance Units/Shares. Each Performance Unit will have an initial value that is
established by the Administrator on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. 

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions
(including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service
Providers. The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award of Performance Units/Shares will

  

 -12- 

 
be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator
may set performance objectives based upon the achievement of Company-wide, divisional, or individual goals, applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 

(d) Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance Units/Shares
will be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting
provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Performance Unit/Share. 

(e) Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as
practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of
the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof.

11. Leaves of Absence/Transfer Between Locations. Unless the Administrator provides otherwise, vesting of
Awards granted hereunder will be suspended during any unpaid leave of absence. A Service Provider will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the
Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If
reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then three (3) months following the ninety-first
(91st) day of such leave any Incentive Stock Option
held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 

12. Transferability of Awards. 

(a) General. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, such
Award will contain such additional terms and conditions as the Administrator deems appropriate. 
 (b) Award Transfer
Program. Notwithstanding any contrary provision of the Plan, the Administrator shall have all discretion and authority to determine and implement the terms and conditions of any Award Transfer Program instituted pursuant to this
Section 12(b) and shall 
  

 -13- 

 
have the authority to amend the terms of any Award participating, or otherwise eligible to participate in, the Award Transfer Program, including (but not limited to) the authority to
(i) amend (including to extend) the expiration date, post-termination exercise period and/or forfeiture conditions of any such Award, (ii) amend or remove any provisions of the Award relating to the Award holder’s continued service to
the Company, (iii) amend the permissible payment methods with respect to the exercise or purchase of any such Award, (iv) amend the adjustments to be implemented in the event of changes in the capitalization and other similar events with
respect to such Award, and (v) make such other changes to the terms of such Award as the Administrator deems necessary or appropriate in its sole discretion. 

13. Adjustments Upon Changes in Capitalization; Dissolution or Liquidation; Merger or Change in Control. 

(a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common
Stock which have been authorized for issuance under the Plan, including Shares as to which no Award have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Award and including the annual increase provided
for in Section 3, the number of shares of Common Stock covered by each outstanding Award and/or the price per share of Common Stock covered by each such outstanding Award, shall be proportionately adjusted for any dividend or other distribution
(whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other
securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. Such
adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Notwithstanding the preceding, the number of Shares subject to any Award always shall be a whole number. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Award. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior
to the consummation of such proposed action. 
 (c) Merger or Change in Control. In the event of a merger or Change in
Control, each outstanding Award will be treated as the Administrator determines, including, without limitation, that each Award be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. The Administrator will not be required to treat all Awards similarly in the transaction. 
 In the event
that the successor corporation does not assume or substitute for the Award, the Participant will fully vest in and have the right to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such
Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units 

 

 -14- 

 
will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels
and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or substituted in the event of a Change in Control, the Administrator will notify the Participant in writing or electronically that the
Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 

For the purposes of this subsection (c), an Award will be considered assumed if, following the Change in Control, the Award confers the
right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) received in the Change in Control by holders of Common Stock for
each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration
received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an
Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Unit or Performance Share, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the Change in Control. 
 Notwithstanding anything
in this Section 13(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals
without the Participant’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award
assumption. 
 (d) Outside Director Awards. With respect to Awards granted to an Outside Director that are assumed or
substituted for, if on the date of or following such assumption or substitution the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the
Participant (unless such resignation is at the request of the acquirer), then the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those
Shares which would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Performance Units and Performance Shares, all performance goals or other vesting criteria
will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. 
  

 -15- 

 14. Tax Withholding. 

(a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof), the Company
will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to
be withheld with respect to such Award (or exercise thereof). 
 (b) Withholding Arrangements. The Administrator, in its
sole discretion and pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (a) paying cash, (b) electing to have the
Company withhold otherwise deliverable cash or Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, or (c) delivering to the Company already-owned Shares having a Fair Market Value equal to the
minimum statutory amount required to be withheld. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 

15. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to
continuing the Participant’s relationship as a Service Provider with the Company, nor will they interfere in any way with the Participant’s right or the Company’s right to terminate such relationship at any time, with or without
cause, to the extent permitted by Applicable Laws. 
 16. Date of Grant. The date of grant of an Award will be, for all
purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time
after the date of such grant. 
 17. Term of Plan. Subject to Section 21 of the Plan, the Plan will become effective
upon its adoption by the Board. It will continue in effect for a term of ten (10) years from the date adopted by the Board, unless terminated earlier under Section 18 of the Plan. 

18. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable
to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment, alteration, suspension or
termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company. Termination of the
Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

 

 -16- 

 19. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the
issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such
Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required. 
 20. Inability to Obtain Authority. The inability of the Company to obtain authority from
any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or
sell such Shares as to which such requisite authority will not have been obtained. 
 21. Stockholder Approval. The Plan
will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting, vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or any Common

 (c) Effect of Administrator’s Decision. All decisions,
determinations and interpretations of the Administrator will be final and binding on all Participants. 
 5. Eligibility.
Nonstatutory Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 

6. Stock Options. 

(a) Term of Option. The term of each Award will be stated in the Award Agreement; provided, however, that the term will be no more
than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Participant who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 

(b) Option Exercise Price and Consideration. 

(i) Exercise Price. The per share exercise price for the Shares to be issued upon exercise of an Option will be such price as is
determined by the Administrator, but will be subject to the following: 
 (A) In the case of an Incentive Stock Option

 a) granted to an Employee who, at the time of grant of such Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant. 

 

 4 

 b) granted to any other Employee, the per Share exercise price will be no less than 100% of
the Fair Market Value per Share on the date of grant. 
 (B) In the case of a Nonstatutory Stock Option, the per Share exercise
price will be determined by the Administrator. 
 (C) Notwithstanding the foregoing, Incentive Stock Options may be granted
with a per Share exercise price other than as required above in accordance with and pursuant to a transaction described in Section 424 of the Code. 

(ii) Forms of Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the
method of payment, will be determined by the Administrator (and, in the case of an Incentive Stock Option, will be determined at the time of grant). Such consideration may consist of, without limitation, (1) cash, (2) check,
(3) promissory note, (4) other Shares, provided Shares acquired directly from the Company (x) have been owned by the Participant, and not subject to a substantial risk of forfeiture, for more than six months on the date of surrender,
and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised, (5) consideration received by the Company under a cashless exercise program
implemented by the Company in connection with the Plan, or (6) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator will consider if acceptance of such
consideration may be reasonably expected to benefit the Company. 
 (c) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms
hereof at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed exercised when the Company receives (i) written or electronic notice of exercise (in accordance with the
Award Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised, together with any applicable withholding taxes. Full payment may consist of any consideration
and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the
Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a
stockholder will exist with respect to the Shares, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other
right for which the record date is prior to the date the Shares are issued, except as provided in Section 11 of the Plan. 

Exercise of an Option in any manner will result in a decrease in the number of Shares thereafter available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (ii) Termination of
Relationship as a Service Provider. If a Participant ceases to be a Service Provider, such Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on
the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three
(3) months following the Participant’s termination. Unless the Administrator provides otherwise, if on the date of termination the Participant is not vested as to his or 

 

 5 

 
her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If, after termination, the Participant does not exercise his or her Option within the time
specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s
Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such
Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination. Unless the Administrator provides
otherwise, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If, after termination, the Participant does not exercise his or
her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised within such period of time
as is specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior
to Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the
person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve
(12) months following the Participant’s termination. If, at the time of death, the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If
the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(d) Incentive Stock Option Limit. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any
calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(d), Incentive Stock Options will be taken into account in
the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. 

7. Stock Purchase Rights. 

(a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted
under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it will advise the offeree in writing of the terms, conditions and restrictions related to the
offer, including the number of Shares that such person will be entitled to purchase, vesting, the price to be paid, and the time within which such person must accept such offer. 

(b) Repurchase Option. Unless the Administrator determines otherwise, the Award Agreement will grant the Company a repurchase
option exercisable within ninety (90) days of the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). Unless the Administrator provides otherwise, the purchase
price for Shares repurchased pursuant to the Award Agreement will be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option will lapse at such rate as the
Administrator may determine. 
 (c) Other Provisions. The Award Agreement will contain such other terms, provisions and
conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 (d) Rights as
a Stockholder. Once the Stock Purchase Right is exercised, the purchaser will have rights equivalent to those of a stockholder and will be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent
of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 11 of the Plan. 

 

 6 

 8. Restricted Stock and Restricted Stock Units. 

(a) Grant. Shares of Restricted Stock and/or Restricted Stock Units may be granted either alone, in addition to, or in tandem with
other awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Restricted Stock and/or Restricted Stock Units under the Plan, it will advise the offeree in writing of the terms,
conditions and restrictions related to the offer, including the applicable number of Shares of Restricted Stock or the number of Restricted Stock Units, as the case may be, that such person will be entitled to receive, the vesting terms, the price
to be paid if any, and the time within which such person must accept such offer. 
 (b) Repurchase Option. Unless the
Administrator determines otherwise, the Company will have an option to repurchase vested Restricted Stock and/or Restricted Stock Units within ninety (90) days of the voluntary or involuntary termination of the holder’s service with the
Company for any reason (including death or disability) at fair market value as determined in good faith by the Administrator. To the extent that the holder purchased Shares granted under a Restricted Stock Award and any such Shares remain non-vested
at the time the grantee ceases to be a Service Provider, the cessation of Service Provider status shall cause an immediate sale of such non-vested Shares to the Company at the original price per Share paid by the grantee. 

(c) Other Provisions. The Award Agreement will contain such other terms, provisions and conditions not inconsistent with the Plan
as may be determined by the Administrator in its sole discretion. 
 (d) Rights as a Stockholder. Once shares of
Restricted Stock have vested, the holder will be a stockholder and his or her ownership will entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record
date is prior to the date such Restricted Stock is vested, except as provided in Section 11 of the Plan. Owners of Restricted Stock Units shall have no rights as stockholders by virtue of such ownership. 

9. Tax Withholding. Prior to the delivery of any Shares pursuant to an Award (or exercise thereof), the Company will have the
power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes (including the Participant’s FICA obligation) required to be withheld
with respect to such Award (or exercise thereof). The Administrator, in its sole discretion and pursuant to such procedures as it may specify from time to time, will determine in what manner it will allow a Participant to satisfy such tax
withholding obligation. 
 10. Transferability of Awards. Unless determined otherwise by the Administrator, Awards may
not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or the laws of descent and distribution, and may be exercised during the lifetime of the Participant, only by the Participant. 

11. Leaves of Absence. 

(a) Unless the Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of
absence. 
 (b) A Service Provider will not cease to be an Employee in the case of (A) any leave of absence approved by
the Company or (B) transfers between locations of the Company or between the Company, its Parent, any Subsidiary, or any successor. 

(c) For purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment
upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then three (3) months following the
91st day of such leave, any Incentive Stock Option held by
the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option.

 12. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or
other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate
structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, may (in its sole discretion) adjust the number
and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will
notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action.

 (c) Merger or Change in Control. In the event of a merger of the Company with or into another corporation, or a
Change in Control, each outstanding Award, and, if applicable, Shares of Restricted Stock acquired pursuant thereto, will be assumed or an equivalent award substituted by the successor corporation or a Parent or Subsidiary of the successor
corporation. In the event that the successor corporation in a merger or Change in Control refuses to assume or substitute for an Award and, if applicable, Shares of Restricted Stock acquired pursuant thereto, then the Participant will fully vest in
and have the right to exercise the Award as to all of the Shares subject thereto, including Shares as to which it would not otherwise be vested or exercisable, and all restrictions on Restricted Stock will lapse. If an Award is not assumed or
substituted in the event of a merger or Change in Control, the Administrator will notify the Participant in writing or electronically that the Award will be exercisable for a period of time as determined by the Administrator, and the Award will
terminate upon expiration of such period for no consideration, unless otherwise determined by the Administrator. 
 For the
purposes of this subsection (c), the Award will be considered assumed if, following the merger or Change in Control, the award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or Change in
Control, the consideration (whether stock, cash, or other securities or property) received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a
choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor
corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Award, for each Share subject to the Award, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per Share consideration received by holders of Common Stock in the merger or Change in Control. 

13. Time of Granting Awards. The date of grant of an Award will, for all purposes, be the date on which the Administrator makes
the determination granting such Award, or such later date as is determined by the Administrator. Notice of the determination will be given to each Service Provider to whom an Award is so granted within a reasonable time after the date of such grant.

 14. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon any Participant any right with
respect to continuing the Participant’s relationship as a Service Provider with the Company, nor will it interfere in any way with his or her right or the Company’s right to terminate such relationship at any time, with or without cause,
and with or without notice. 
 15. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the
issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

 

 8 

 (b) Investment Representations. As a condition to the exercise of an Award, the
Administrator may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in
the opinion of counsel for the Company, such a representation is required. 
 16. Inability to Obtain Authority. The
inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of
any liability in respect of the failure to issue or sell such Shares as to which such requisite authority will not have been obtained. 

17. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of
Shares as will be sufficient to satisfy the requirements of the Plan. 
 18. Stockholder Approval. The Plan will be
subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted. Such stockholder approval will be obtained in the degree and manner required under Applicable Laws. 

19. Term of Plan. Subject to stockholder approval in accordance with Section 18, the Plan will become effective upon its
adoption by the Board. Unless sooner terminated under Section 20, it will continue in effect for a term of ten (10) years from the later of (i) the effective date of the Plan, or (ii) the earlier of the most recent Board or
stockholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 20. Amendment and
Termination of the Plan. 
 (a) Amendment and Termination. The Board may at any time amend, alter, suspend or
terminate the Plan. 
 (b) Stockholder Approval. The Board will obtain stockholder approval of any Plan amendment to the
extent necessary and desirable to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment,
alteration, suspension or termination of the Plan will materially impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant
and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

of in any manner other than by will or the laws of descent and distribution, and may be exercised during the lifetime of the Participant, only by the Participant. If the Administrator in its sole discretion makes an Award transferable, such Award
may only be transferred (i) by will, (ii) by the laws of descent and distribution, or (iii) to family members (within the meaning of Rule 701 of the Securities Act) through gifts or domestic relations orders, as permitted by Rule 701
of the Securities Act. 
 (g) Except in the case of Options granted to officers, Directors and Consultants, Options will become

(h) If a Participant ceases to be a Service Provider, such Participant may exercise his or her Option within thirty (30) days of
termination, or such longer period of time as specified in the Award Agreement, to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Award
Agreement). 
 (i) If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the
Participant may exercise his or her Option within six (6) months of termination, or such longer period of time as specified in the Award Agreement, to the extent the Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Award Agreement). 
  

 10 

 (j) If a Participant dies while a Service Provider, the Option may be exercised within six
(6) months following Participant’s death, or such longer period of time as specified in the Award Agreement, to the extent that the Option is vested on the date of death (but in no event later than the expiration of the term of such Option
as set forth in the Award Agreement) by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. 

(k) The terms of any Stock Purchase Rights offered under this Appendix A will comply in all respects with Section 260.140.42 of
Title 10 of the California Code of Regulations including, without limitation:

 (m) The Company will provide to each Participant and to each
individual who acquires Shares pursuant to the Plan, not less frequently than annually during the period such Participant has one or more Awards outstanding, and, in the case of an individual who acquires Shares pursuant to the Plan, during the
period such individual owns such Shares, copies of annual financial statements. The Company will not be required to provide such statements to key employees whose duties in connection with the Company assure their access to equivalent information.

 (n) In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other
property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure
of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, may (in its sole discretion) adjust the number and class
of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award; provided, however, that the Administrator will make such adjustments to the extent required by Section 25102(o) of
the California Corporations Code.

authority to amend this Appendix A in accordance with Section 19 of the Plan.
