Plan or the Amended and Restated 2015 Stock Plan, as amended (together, the “Legacy Plans”) that, after the date of Board approval of this Plan, expire or otherwise terminate without having been exercised in full, and Shares issued

 -5- 








 (b)    Automatic
Share Reserve Increase. The number of Shares available for issuance under the Plan will be increased on January
1st of each year following the year in which the Plan becomes effective and ending on the date that the Plan terminates in accordance with Section 19, in an amount equal to the lesser of (i) 1,500,000 Shares or (ii) 5% of the total number of
Shares outstanding on December 31st of the preceding calendar year. Notwithstanding the foregoing, the Board may act prior to January 1st of a given year to provide that there will be no January 1st increase for such year or that the increase for
such year will be a lesser number of Shares than provided herein. 
 (c)    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 the 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 due to the failure to
vest, 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 withholdings 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 15, 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 Code Section 422 and the
Treasury Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Section 3(b) and 3(c). 

(d)    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. 

  
 -6- 








 (ii)    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. 

(iii)    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; 

(v)    to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder.
Such terms and 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; 

(vi)    to institute and determine the terms and conditions of an Exchange Program; 

(vii)    to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 

(viii)    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 non-U.S. laws or for qualifying for favorable tax treatment under applicable non-U.S. laws; 
 (ix)    to modify or amend each Award (subject to Section 20(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) of the Plan regarding Incentive Stock
Options); 
 (x)    to allow Participants to satisfy tax withholding obligations in a manner prescribed in
Section 15(d); 

  
 -7- 








 (xi)    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; 
 (xii)    to temporarily
suspend the exercisability of an Award if the Administrator deems such suspension to be necessary or appropriate for administrative purposes; 

(xiii)    to allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that otherwise
would 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 and will be given the maximum deference permitted by Applicable Laws. 

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)    Grant of Options. Subject to the terms and provisions of the Plan, the Administrator, at any time and from
time to time, may grant Options in such amounts as the Administrator, in its sole discretion, will determine. 

(b)    Option Agreement. Each Award of an Option will be evidenced by an Award Agreement that will specify the
exercise price, the term of the Option, the number of Shares subject to the Option, the exercise restrictions, if any, applicable to the Option, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 

(c)    Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. Notwithstanding such designation, however, 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(c), 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, and the calculation will be performed in accordance with
Code Section 422 and Treasury Regulations promulgated thereunder. 
 (d)    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, as determined by the Administrator,
in its sole discretion. In the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is 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. 

  
 -8- 








 (e)    Option Exercise Price and Consideration. 

(i)    Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the 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 provisions
of this Section 6(e), 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, Code Section 424(a). 
 (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, to the extent permitted by Applicable Laws, (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 further that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion; (5) consideration received by the Company
under a broker assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net exercise; (7) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws, or (8) 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. 

  
 -9- 








 (f)    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 tax withholding). 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 15 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. 

  
 -10- 








 (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. 

(v)    Tolling Expiration. A Participant’s Award Agreement may also provide that: 

(1)    if the exercise of the Option following the termination of Participant’s status as a Service Provider (other
than upon the Participant’s death or Disability) would result in liability under Section 16(b), then the Option will terminate on the earlier of (A) the expiration of the term of the Option set forth in the Award Agreement, or
(B) the tenth (10th) day after the last date on which such exercise would result in liability under Section 16(b); or 

(2)    if the exercise of the Option following the termination of the Participant’s status as a Service Provider
(other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of Shares would violate the registration requirements under the Securities Act, then the Option will terminate on the earlier of
(A) the expiration of the term of the Option or (B) the expiration of a period of thirty (30)-day period after the termination of the Participant’s status as a Service Provider during which the
exercise of the Option would not be in violation of such registration requirements. 
 7.    Stock Appreciation
Rights. 
 (a)    Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock
Appreciation Right 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. 

(b)    Number of Shares. The Administrator will have complete discretion to determine the number of Shares subject
to any Award of Stock Appreciation Rights. 
 (c)    Exercise Price and Other Terms. The per Share exercise price
for the Shares that will determine the amount of the payment to be received upon exercise of a Stock Appreciation Right as set forth in Section 7(f) will be determined by the Administrator and will be no less than


  
 -11- 








 
one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Otherwise, 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 ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement, as determined by the Administrator, in its sole discretion. Notwithstanding the
foregoing, the rules of Section 6(f) relating to exercise 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. 

8.    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 8 or as may be provided in the Award Agreement, as determined by the Administrator, in its sole discretion, 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. 

  
 -12- 








 (e)    Removal of Restrictions. Except as otherwise provided in this
Section 8, 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. 

(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. 

9.    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, divisional, business unit, or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws, 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 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. 

  
 -13- 








 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 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,
business unit or individual goals (including, but not limited to, continued employment or service), 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. 

(f)    Cancellation of Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or
unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 

11.    Outside Director Limitations. No Outside Director may be granted, in any Fiscal Year, Awards with a grant
date fair value (determined in accordance with U.S. generally accepted accounting principles) of more than $500,000, increased to $750,000 in connection with his or her initial service. Any Awards granted to an individual while he or she was an
Employee, or while he or she was a Consultant but not an Outside Director, will not count for purposes of the limitations under this Section 11. 

  
 -14- 








 12.    Compliance With Code Section 409A. Awards
will be designed and operated in such a manner that they are either exempt from the application of, or comply with, the requirements of Code Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional
tax or interest applicable under Code Section 409A, except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Code Section 409A
and will be construed and interpreted in accordance with such intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Code
Section 409A the Award will be granted, paid, settled or deferred in a manner that will meet the requirements of Code Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest
applicable under Code Section 409A. In no event will the Company have any obligation under the terms of this Plan to reimburse a Participant for any taxes or other costs that may be imposed on Participant as a result of Section 409A. 

13.    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 Participant 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 three (3) months, 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 six (6) months following the first (1st) 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. 

14.    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 by the laws of descent and 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. 
 15.    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, will adjust the number and class of shares of stock that may be delivered under the Plan and/or the number, class, and price of
shares of stock covered by each outstanding Award, and the numerical Share limits of Sections 3. 

  
 -15- 








 (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)    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 (or portion thereof), 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 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 all cases, unless specifically provided otherwise under the applicable Award Agreement or other written agreement
between the Participant and the Company or any of its Subsidiaries or Parents, as applicable. In addition, if an Option or Stock Appreciation Right 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 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 15(c) and subsection 15(d), an 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 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 merger or Change in Control. 

Notwithstanding anything in this Section 15(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, in
all cases, unless specifically provided otherwise under the applicable Award Agreement or other written agreement between the Participant and the Company or any of its Subsidiaries or Parents, as applicable; 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. 

  
 -16- 








 Notwithstanding anything in this Section 15(c) to the contrary, and unless otherwise
provided in an Award Agreement, if an Award that vests, is earned or paid-out under an Award Agreement is subject to Code Section 409A and if the change in control definition contained in the Award
Agreement does not comply with the definition of “change of control” for purposes of a distribution under Code Section 409A, then any payment of an amount that is otherwise accelerated under this Section will be delayed until the
earliest time that such payment would be permissible under Code Section 409A without triggering any penalties applicable under Code Section 409A. 

(d)    Outside Director Awards. In the event of a Change in Control, with respect to Awards granted to an Outside
Director, the Outside Directors 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 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, unless specifically provided otherwise under the applicable Award Agreement or other written agreement between the Outside Director and the Company or any of its Subsidiaries or Parents, as applicable.

 16.    Tax Withholding. 

(a)    Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise
thereof) or such earlier time as any tax withholding obligation is due, 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 such methods as the Administrator shall determine, including, without limitation, (i) paying cash, (ii) 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 such greater amount as the Administrator may determine if such amount would not have adverse
accounting consequences, as the Administrator determines in its sole discretion, (iii) delivering to the Company already-owned Shares having a fair market value not exceeding the maximum statutory amount required to be withheld or such greater
amount as the Administrator may determine, in each case, provided the delivery of such Shares will not result in any adverse accounting consequences, as the Administrator determines in its sole discretion, (iv) selling a sufficient number of
Shares otherwise deliverable to the Participant through such means as the Administrator may determine in its sole discretion (whether through a broker or otherwise) equal to the amount required to be withheld, or (v) any combination of the
foregoing methods of payment. The amount of the withholding requirement will be deemed to include any amount which the Administrator agrees may be withheld at the time the election is made, not to exceed the amount determined by using the maximum
federal, state or local marginal income tax rates applicable to the Participant with respect 

  
 -17- 








 
to the Award on the date that the amount of tax to be withheld is to be determined or such greater amount as the Administrator may determine if such amount would not have adverse accounting
consequences, as the Administrator determines in its sole discretion. 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. 

17.    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 or its Subsidiaries or Parents, as applicable, nor will they interfere in any way with the Participant’s right or the right of the Company and
its Subsidiaries or Parents, as applicable to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 

18.    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. 

19.    Term of Plan. Subject to Section 23 of the Plan, the Plan will become effective upon its approval
by the Company’s stockholders. It will continue in effect for a term of ten (10) years from the date adopted by the Board, unless terminated earlier under Section 20 of the Plan. 

20.    Amendment and Termination of the Plan. 

(a)    Amendment and Termination. The Administrator 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 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. 

21.    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. 

  
 -18- 








 22.    Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any registration or other qualification of the Shares under any U.S. federal or state law or
non-U.S. law or under the rules and regulations of the Securities and Exchange Commission, the stock exchange on which Shares of the same class are then listed, or any other governmental or regulatory body,
which authority, registration, qualification or rule compliance is deemed by the Company’s counsel to be necessary or advisable for the 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, registration, qualification or rule compliance will not have been obtained. 

23.    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. 

24.    Forfeiture Events. 

(a)    All Awards under the Plan will be subject to recoupment under any clawback policy that the Company is required to
adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other
Applicable Laws. In addition, the Administrator may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Administrator determines necessary or appropriate, including but not limited to a reacquisition right
regarding previously acquired Shares or other cash or property. Unless this Section 24 is specifically mentioned and waived in an Award Agreement or other document, no recovery of compensation under a clawback policy or otherwise will be an
event that triggers or contributes to any right of a Participant to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company or a Subsidiary or Parent of the Company. 

(b)    The Administrator may specify in an Award Agreement that the Participant’s rights, payments, and benefits with
respect to an Award will be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but
will not be limited to, termination of such Participant’s status as Service Provider for cause or any specified action or inaction by a Participant, whether before or after such termination of service, that would constitute cause for
termination of such Participant’s status as a Service Provider.
