Plan and Awards; and to otherwise do all things necessary or desirable to carry out the purposes of the Plan or any Award. Determinations of the Administrator made with respect to the Plan or any Award are conclusive and bind all persons. 

 

	4.	 SHARE POOL; LIMITS ON AWARDS 

(a)    Number of Shares. Subject to adjustment as provided in Section 7(b) below, the
maximum number of shares of Stock that may be delivered in satisfaction of Awards under the Plan is (i) 47,037,113 shares (the “Initial Share Pool”). The Initial Share Pool will automatically increase on January 1st of each year beginning in 2022 and continuing through and including 2031 by the lesser of (i) five percent (5%) of the number of shares of Stock outstanding as of the close of business on the
immediately preceding December 31st and (ii) the number of shares of Stock determined by the Board on or prior to such date for such year (the Initial Share Pool, as it may be so increased,
the “Share Pool”). Up to 47,037,113 shares of Stock from the Share Pool may be delivered in satisfaction of ISOs, but nothing in this Section 4(a) will be construed as requiring that any, or any fixed number of, ISOs be awarded
under the Plan. For purposes of this Section 4(a), shares of Stock shall not be treated as delivered under the Plan, and will not reduce the Share Pool, unless and until, and to the extent, they are actually delivered to a Participant. Without
limiting the generality of the foregoing, the number of shares of Stock delivered in satisfaction of Awards will be determined (i) by excluding shares of Stock withheld by the Company in payment of the exercise price or purchase price of the
Award or in satisfaction of tax withholding requirements with respect to the Award, (ii) by including only the number of shares of Stock delivered in settlement of a SAR any portion of which is settled in Stock, and (iii) by excluding any
shares of Stock underlying Awards settled in cash or that expire, become unexercisable, terminate or are forfeited to or repurchased by the Company, in each case, without the delivery of Stock (or retention, in the case of Restricted Stock or
Unrestricted Stock). For the avoidance of 

 
doubt, the Share Pool will not be increased by any shares of Stock delivered under the Plan that are subsequently repurchased using proceeds directly attributable to Stock Option exercises. The
limits set forth in this Section 4(a) will be construed to comply with the applicable requirements of Section 422. 

(b)     Substitute Awards. The Administrator may grant Substitute Awards under the
Plan. To the extent consistent with the applicable requirements of Section 422 and the regulations thereunder and other applicable legal requirements (including applicable stock exchange requirements), shares of Stock delivered in respect of
Substitute Awards will be in addition to and will not reduce the Share Pool. Notwithstanding the foregoing or anything in Section 4(a) to the contrary, if any Substitute Award is settled in cash or expires, becomes unexercisable, terminates or
is forfeited to or repurchased by the Company without the delivery (or retention, in the case of Restricted Stock or Unrestricted Stock) of Stock, the shares of Stock previously subject to such Substitute Award will not increase the Share Pool or
otherwise be available for future grant under the Plan. The Administrator will determine the extent to which the terms and conditions of the Plan apply to Substitute Awards, if at all; provided, however, that Substitute Awards will not be
subject to the limits described in Section 4(d) below. 
 (c)    Type of Shares. Stock
delivered by the Company under the Plan may be authorized but unissued Stock, treasury Stock or previously issued Stock acquired by the Company. No fractional shares of Stock will be delivered under the Plan. 

(d)    Non-Employee Director Limits. Beginning in
calendar year 2022, the aggregate value of all compensation granted or paid to any Director with respect to any calendar year, including Awards granted under the Plan and cash fees or other compensation paid by the Company to such Director outside
of the Plan for services as a Director during such calendar year, may not exceed $750,000 in the aggregate ($1,000,000 in the aggregate with respect to a Director’s first calendar year of service on the Board), calculating the value of any
Awards based on the grant date fair value in accordance with the Accounting Rules, assuming a maximum payout. For the avoidance of doubt, the limitation in this Section 4(d) will not apply to any compensation granted or paid to a Director for
services to the Company or an affiliate other than as a Director, including, without limitation, as a consultant or advisor to the Company or an affiliate. 
  

	5.	 ELIGIBILITY AND PARTICIPATION 

The Administrator will select Participants from among Employees and Directors of, and consultants and advisors to, the Company and its
affiliates; provided, however, that, subject to such express exceptions, if any, as the Administrator may establish, eligibility shall be further limited to those persons as to whom the use of a
Form S-8 registration statement is permissible. Eligibility for ISOs is limited to individuals described in the first sentence of this Section 5 who are employees of the Company or of a
“parent corporation” or “subsidiary corporation” of the Company as those terms are defined in Section 424 of the Code. Eligibility for Stock Options, other than ISOs, and SARs is limited to individuals described in the first
sentence of this Section 5 who are providing direct services on the date of grant of the Award to the Company or to a subsidiary of the Company that would be described in the first sentence of
Section 1.409A-1(b)(5)(iii)(E) of the Treasury Regulations.

	6.	 RULES APPLICABLE TO AWARDS 

 

	 	(a)	 All Awards. 

(1)    Award Provisions. The Administrator will determine the terms and conditions of all
Awards, subject to the limitations provided herein. By accepting (or, under such rules as the Administrator may prescribe, being deemed to have accepted) an Award, the Participant will be deemed to have agreed to the terms and conditions of the
Award and the Plan. Notwithstanding any provision of the Plan to the contrary, Substitute Awards may contain terms and conditions that are inconsistent with the terms and conditions specified herein, as determined by the Administrator. 

(2)    Term of Plan. No Awards may be made after ten years from the Date of Adoption, but
previously granted Awards may continue beyond that date in accordance with their terms. 

(3)    Transferability. Neither ISOs nor, except as the Administrator otherwise expressly
provides in accordance with the third sentence of this Section 6(a)(3), other Awards may be transferred other than by will or by the laws of descent and distribution. During a Participant’s lifetime, ISOs and, except as the Administrator
otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), SARs and NSOs may be exercised only by the Participant. The Administrator may permit the gratuitous transfer (i.e., transfer not for value) of
Awards other than ISOs, including for estate planning purposes, subject to applicable securities and other laws and such terms and conditions as the Administrator may determine. 

(4)    Vesting; Exercisability. The Administrator will determine the time or times at which an
Award vests or becomes exercisable and the terms and conditions on which a Stock Option or SAR remains exercisable. Without limiting the foregoing, the Administrator may at any time accelerate the vesting and/or exercisability of an Award (or any
portion thereof), regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration. Unless the Administrator expressly provides otherwise, however, the following rules will apply if a Participant’s
Employment ceases: 
 (A)    Except as provided in (B) and (C) below, immediately upon the
cessation of the Participant’s Employment, each Stock Option and SAR (or portion thereof) that is then held by the Participant or by the Participant’s permitted transferees, if any, will cease to be exercisable and will terminate and each
other Award that is then held by the Participant or by the Participant’s permitted transferees, if any, to the extent not then vested, will be forfeited. 

(B)    Subject to (C) and (D) below, each Stock Option and SAR (or portion thereof) held by the
Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment, to the extent then vested and exercisable, will remain exercisable for the lesser of (i) a period of
three months following such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate.

  
 3 

 (C)    Subject to (D) below, each Stock
Option and SAR (or portion thereof) held by a Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment due to the Participant’s death or by the Company due to
the Participant’s Disability, to the extent then vested and exercisable, will remain exercisable for the lesser of (i) the one-year period ending on the first anniversary of such cessation of
Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate. 

(D)    All Awards (whether or not vested or exercisable) held by a Participant or the
Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment will immediately terminate upon (i) such cessation of Employment if the termination is for Cause or occurs in
circumstances that in the determination of the Administrator would have constituted grounds for the Participant’s Employment to be terminated for Cause (in each case, without regard to the lapsing of any required notice or cure periods in
connection therewith) or (ii) to the maximum extent permitted under applicable law, the Participant’s violation of any non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention assignment, or other restrictive covenant in favor of the Company or any of its affiliates by which the Participant is
bound. 
 (5)    Recovery of Compensation. The Administrator may provide in any case that any
outstanding Award (whether or not vested or exercisable), the proceeds from the exercise or disposition of any Award or Stock acquired under any Award, and any other amounts received in respect of any Award or Stock acquired under any Award will be
subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the Participant to whom the Award was granted is not in compliance with any provision of the Plan or any applicable Award, or violates any non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention
assignment, or other restrictive covenant in favor of the Company or any of its affiliates by which the Participant is bound. Each Award will be subject to any policy of the Company or any of its affiliates that relates to trading on non-public information and permitted transactions with respect to shares of Stock, including limitations on hedging and pledging. In addition, each Award will be subject to any policy of the Company or
any of its affiliates that provides for forfeiture, disgorgement, or clawback with respect to incentive compensation that includes Awards under the Plan and will be further subject to forfeiture and disgorgement to the extent required by law or
applicable stock exchange listing standards, including, without limitation, Section 10D of the Exchange Act. Each Participant, by accepting or being deemed to have accepted an Award under the Plan, agrees (or will be deemed to have agreed) to
the terms of this Section 6(a)(5) and to any clawback, recoupment or similar policy of the Company or any of its affiliates and further agrees (or will be deemed to have further agreed) to cooperate fully with the Administrator, and to cause
any and all permitted transferees of the Participant to cooperate fully with the Administrator, to effectuate any forfeiture or disgorgement described in this Section 6(a)(5). Neither the Administrator nor the Company nor any other person,
other than the Participant and the Participant’s permitted transferees, if any, will be responsible for any adverse tax or other consequences to a Participant or the Participant’s permitted transferees, if any, that may arise in connection
with this Section 6(a)(5). 

  
 4 

 (6)    Taxes. The grant of an Award and the
issuance, delivery, vesting and retention of Stock, cash or other property under an Award are conditioned upon the full satisfaction by the Participant of all tax and other withholding requirements with respect to the Award. The Administrator will
prescribe such rules for the withholding of taxes and other amounts with respect to any Award as it deems necessary. Without limitation to the foregoing, the Company or any affiliate of the Company will have the authority and the right to deduct or
withhold (by any means set forth herein or in an Award agreement), or require a Participant to remit to the Company or an affiliate of the Company, an amount sufficient to satisfy all U.S. and non-U.S.
federal, state and local income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to participation in the Plan and any Award hereunder and legally
applicable to the Participant and required by law to be withheld (including, any amount deemed by the Company, in its discretion, to be an appropriate charge to the Participant even if legally applicable to the Company or any affiliate of the
Company). The Administrator, in its sole discretion, may hold back shares of Stock from an Award or permit a Participant to tender previously-owned shares of Stock in satisfaction of tax or other withholding requirements (but not in excess of the
maximum withholding amount consistent with the Award being subject to equity accounting treatment under the Accounting Rules). Any amounts withheld pursuant to this Section 6(a)(6) will be treated as though such amounts had been paid directly
to the applicable Participant. In addition, the Company may, to the extent permitted by law, deduct any such tax and other withholding amounts from any payment of any kind otherwise due to a Participant from the Company or any of its affiliates.

 (7)    Dividend Equivalents. The Administrator may provide for the payment of amounts (on
terms and subject to such restrictions and conditions established by the Administrator) in lieu of cash dividends or other cash distributions with respect to Stock subject to an Award whether or not the holder of such Award is otherwise entitled to
share in the actual dividend or distribution in respect of such Award. Any entitlement to dividend equivalents or similar entitlements will be established and administered either consistent with an exemption from, or in compliance with, the
applicable requirements of Section 409A. 
 (8)    Rights Limited. Nothing in the Plan
or any Award will be construed as giving any person the right to be granted an Award or to continued employment or service with the Company or any of its affiliates, or any rights as a stockholder except as to shares of Stock actually delivered
under the Plan. The loss of existing or potential profit in any Award will not constitute an element of damages in the event of a termination of a Participant’s Employment for any reason, even if the termination is in violation of an obligation
of the Company or any of its affiliates to the Participant. 
 (9)    Coordination with Other
Plans. Shares of Stock and/or Awards under the Plan may be granted in tandem with, or in satisfaction of or substitution for, other Awards under the Plan or awards made under other compensatory plans or programs of the Company or any
of its affiliates. For example, but without limiting the generality of the foregoing, awards under other compensatory plans or programs of the Company or any of its affiliates may be settled in Stock (including, without limitation, Unrestricted
Stock) under the Plan if the Administrator so determines, in which case the shares delivered will be treated as awarded under the Plan (and will reduce the number of shares thereafter available for delivery under the Plan in accordance with the
rules set forth in Section 4). 

  
 5 

 (10)    Section 409A. 

(A)    Without limiting the generality of Section 11(b) hereof, each Award will contain such
terms as the Administrator determines and will be construed and administered such that the Award either qualifies for an exemption from the requirements of Section 409A or satisfies such requirements. 

(B)    Notwithstanding anything to the contrary in the Plan or any Award agreement, the
Administrator may unilaterally amend, modify or terminate the Plan or any outstanding Award, including but not limited to changing the form of the Award, if the Administrator determines that such amendment, modification or termination is necessary
or desirable to avoid the imposition of an additional tax, interest or penalty under Section 409A. 

(C)    If a Participant is determined on the date of the Participant’s termination of
Employment to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then, with regard to any payment that is considered nonqualified deferred compensation under Section 409A, to the
extent applicable, payable on account of a “separation from service”, such payment will be made or provided on the date that is the earlier of (i) the first business day following the expiration of the
six-month period measured from the date of such “separation from service” and (ii) the date of the Participant’s death (the “Delay Period”). Upon the expiration of the
Delay Period, all payments delayed pursuant to this Section 6(a)(10)(C) (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such delay) will be paid, without interest, on the first business
day following the expiration of the Delay Period in a lump sum and any remaining payments due under the Award will be paid in accordance with the normal payment dates specified for them in the applicable Award agreement. 

(D)    For purposes of Section 409A, each payment made under the Plan or any Award will be
treated as a separate payment. 
 (E)    With regard to any payment considered to be nonqualified
deferred compensation under Section 409A, to the extent applicable, that is payable upon a change in control of the Company or other similar event, to the extent required to avoid the imposition of an additional tax, interest or penalty under
Section 409A, no amount will be payable unless such change in control constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations. 

 

	 	(b)	 Stock Options and SARs. 

(1)    Time and Manner of Exercise. Unless the Administrator expressly provides otherwise, no
Stock Option or SAR will be deemed to have been exercised until the Administrator receives a notice of exercise in a form acceptable to the Administrator that is signed by the appropriate person and accompanied by any payment required under the
Award. The Administrator may at any time limit or restrict the exercisability of any Stock Option or SAR in its discretion, including in connection with any Covered Transaction. Any attempt to exercise a Stock Option or SAR by any person other than
the Participant will not be given effect unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so. 

  
 6 

 (2)    Exercise Price. The exercise price
(or the base value from which appreciation is to be measured) per share of each Award requiring exercise must be no less than 100% (in the case of an ISO granted to a 10-percent stockholder within the meaning
of Section 422(b)(6) of the Code, 110%) of the Fair Market Value of a share of Stock, determined as of the date of grant of the Award, or such higher amount as the Administrator may determine in connection with the grant. 

(3)    Payment of Exercise Price. Where the exercise of an Award (or portion thereof) is to be
accompanied by payment, payment of the exercise price must be made by cash or check acceptable to the Administrator or, if so permitted by the Administrator and if legally permissible, (i) through the delivery of previously acquired
unrestricted shares of Stock, or the withholding of unrestricted shares of Stock otherwise deliverable upon exercise, in either case, that have a Fair Market Value equal to the exercise price; (ii) through a broker-assisted cashless exercise
program acceptable to the Administrator; (iii) by other means acceptable to the Administrator; or (iv) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in payment of the exercise
price under clause (i) above may be accomplished either by actual delivery or by constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe. 

(4)    Maximum Term. The maximum term of Stock Options and SARs must not exceed 10 years from
the date of grant (or five years from the date of grant in the case of an ISO granted to a 10-percent stockholder described in Section 6(b)(2) above). 

(5)    No Repricing. Except in connection with a corporate transaction involving the Company
(which term includes, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination or exchange of
shares) or as otherwise contemplated by Section 7 below, the Company may not, without obtaining stockholder approval, (i) amend the terms of outstanding Stock Options or SARs to reduce the exercise price or base value of such Stock Options
or SARs; (ii) cancel outstanding Stock Options or SARs in exchange for Stock Options or SARs that have an exercise price or base value that is less than the exercise price or base value of the original Stock Options or SARs; or
(iii) cancel outstanding Stock Options or SARs that have an exercise price or base value greater than the Fair Market Value of a share of Stock on the date of such cancellation in exchange for cash or other consideration. 

 

	7.	 EFFECT OF CERTAIN TRANSACTIONS 

(a)    Mergers, etc. Except as otherwise expressly provided in an
Award agreement or other agreement or by the Administrator, the following provisions will apply in the event of a Covered Transaction: 

(1)    Assumption or Substitution. If the Covered Transaction is one in which there is an
acquiring or surviving entity, the Administrator may provide for (i) the assumption or continuation of some or all outstanding Awards or any portion thereof or (ii) the grant of new awards in substitution therefor by the acquiror or
survivor or an affiliate of the acquiror or survivor. 

  
 7 

 (2)    Cash-Out of
Awards. Subject to Section 7(a)(5) below, the Administrator may provide for payment (a “cash-out”), with respect to some or all Awards or any portion thereof (including
only the vested portion thereof, with the unvested portion terminating as provided in Section 7(a)(4) below), equal in the case of each applicable Award or portion thereof to the excess, if any, of (i) the Fair Market Value of one share of
Stock multiplied by the number of shares of Stock subject to the Award or such portion, minus (ii) the aggregate exercise or purchase price, if any, of such Award or such portion thereof (or, in the case of a SAR, the aggregate base value above
which appreciation is measured), in each case, on such payment and other terms and subject to such conditions (which need not be the same as the terms and conditions applicable to holders of Stock generally), as the Administrator determines,
including that any amounts paid in respect of such Award in connection with the Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate. For the avoidance of doubt, if the per
share exercise or purchase price (or base value) of an Award or portion thereof is equal to or greater than the Fair Market Value of one share of Stock, such Award or portion may be cancelled with no payment due hereunder or otherwise in respect
thereof. 
 (3)    Acceleration of Certain Awards. Subject to Section 7(a)(5) below,
the Administrator may provide that any Award requiring exercise will become exercisable, in full or in part, and/or that the delivery of any shares of Stock remaining deliverable under any outstanding Award of Stock Units (including Restricted Stock
Units and Performance Awards to the extent consisting of Stock Units) will be accelerated, in full or in part, in each case on a basis that gives the holder of the Award a reasonable opportunity, as determined by the Administrator, following the
exercise of the Award or the delivery of the shares, as the case may be, to participate as a stockholder in the Covered Transaction. 

(4)    Termination of Awards upon Consummation of Covered Transaction. Except as the
Administrator may otherwise determine, each Award will automatically terminate (and in the case of outstanding shares of Restricted Stock, will automatically be forfeited) immediately upon the consummation of the Covered Transaction, other than
(i) any Award that is assumed, continued or substituted for pursuant to Section 7(a)(1) above, and (ii) any Award that by its terms, or as a result of action taken by the Administrator, continues following the Covered Transaction.

 (5)    Additional Limitations. Any share of Stock and any cash or other property or other
award delivered pursuant to Section 7(a)(1), Section 7(a)(2) or Section 7(a)(3) above with respect to an Award may, in the discretion of the Administrator, contain such restrictions, if any, as the Administrator deems appropriate,
including to reflect any performance or other vesting conditions to which the Award was subject and that did not lapse (and were not satisfied) in connection with the Covered Transaction. For purposes of the immediately preceding sentence, a cash-out under Section 7(a)(2) above or an acceleration under Section 7(a)(3) above will not, in and of itself, be treated as the lapsing (or satisfaction) of a performance or other vesting condition. In
the case of Restricted Stock that does not vest and is not forfeited in connection with the Covered Transaction, the Administrator may require that any amounts delivered, exchanged or otherwise paid in respect of such Stock in connection with the
Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the Plan. 

  
 8 

 (6)    Uniform Treatment. For the avoidance
of doubt, the Administrator need not treat Participants or Awards (or portions thereof) in a uniform manner, and may treat different Participants and/or Awards differently, in connection with a Covered Transaction. 

(b)    Changes in and Distributions with Respect to Stock. 

(1)    Basic Adjustment Provisions. In the event of a stock dividend, extraordinary cash
dividend, stock split or combination of shares (including a reverse stock split), recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off, split-up, or other similar change in the Company’s capital structure that constitutes an equity restructuring within the meaning of the Accounting Rules, the Administrator shall make appropriate adjustments to
the maximum number of shares of Stock specified in Section 4(a) that may be delivered under the Plan, and shall make appropriate adjustments to the number and kind of shares of stock or securities underlying Awards then outstanding or
subsequently granted, any exercise or purchase prices (or base values) relating to Awards and any other provision of Awards affected by such change. 

(2)    Certain Other Adjustments. The Administrator may also make adjustments of the type
described in Section 7(b)(1) above to take into account distributions to stockholders other than those provided for in Sections 7(a) and 7(b)(1) above, or any other event, if the Administrator determines that adjustments are appropriate to
avoid distortion in the operation of the Plan or any Award. 
 (3)    Continuing Application of Plan
Terms. References in the Plan to shares of Stock will be construed to include any stock or securities resulting from an adjustment pursuant to this Section 7. 

 

	8.	 LEGAL CONDITIONS ON DELIVERY OF STOCK 

The Company will not be obligated to deliver any shares of Stock pursuant to the Plan or to remove any restriction from shares of Stock
previously delivered under the Plan until: (i) the Company is satisfied that all legal matters in connection with the issuance and delivery of such shares have been addressed and resolved; (ii) if the outstanding Stock is at the time of
delivery listed on any stock exchange or national market system, the shares to be delivered have been listed or authorized to be listed on such exchange or system upon official notice of issuance; and (iii) all conditions of the Award have been
satisfied or waived. The Company may require, as a condition to the exercise of an Award or the delivery of shares of Stock under an Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of
the Securities Act of 1933, as amended, or any applicable state or non-U.S. securities law. Any Stock delivered to Participants under the Plan will be evidenced in such manner as the Administrator determines
appropriate, including book-entry registration or delivery of stock certificates. In the event that the Administrator determines that stock certificates will be issued in connection with Stock issued under the Plan, the Administrator may require
that such certificates bear an appropriate legend reflecting any restriction on transfer applicable to such Stock, and the Company may hold the certificates pending the lapse of the applicable restrictions. 

  
 9 

	9.	 AMENDMENT AND TERMINATION 

The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time be permitted by
applicable law, and may at any time terminate the Plan as to any future grants of Awards; provided, however, that except as otherwise expressly provided in the Plan or the applicable Award, the Administrator may not, without the
Participant’s consent, alter the terms of an Award so as to affect materially and adversely the Participant’s rights under the Award, unless the Administrator expressly reserved the right to do so in the Plan or at the time the applicable
Award was granted. Any amendments to the Plan will be conditioned upon stockholder approval only to the extent, if any, such approval is required by applicable law (including the Code) or stock exchange requirements, as determined by the
Administrator. For the avoidance of doubt, without limiting the Administrator’s rights hereunder, no adjustment to any Award pursuant to the terms of Section 7 or Section 12 will be treated as an amendment requiring a
Participant’s consent. 
  

	10.	 OTHER COMPENSATION ARRANGEMENTS 

The existence of the Plan or the grant of any Award will not affect the right of the Company or any of its affiliates to grant any person
bonuses or other compensation in addition to Awards under the Plan. 
  

	11.	 MISCELLANEOUS 

(a)    Waiver of Jury Trial. By accepting or being deemed to have accepted an Award under the
Plan, each Participant waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under the Plan or any Award, or
under any amendment, waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will be deemed to have agreed) that any such action, proceedings or counterclaim
will be tried before a court and not before a jury. By accepting (or being deemed to have accepted) an Award under the Plan, each Participant certifies that no officer, representative, or attorney of the Company has represented, expressly or
otherwise, that the Company would not, in the event of any action, proceeding or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in the Plan, nothing herein is to be construed as limiting the ability of
the Company and a Participant to agree to submit any dispute arising under the terms of the Plan or any Award to binding arbitration or as limiting the ability of the Company to require any individual to agree to submit such disputes to binding
arbitration as a condition of receiving an Award hereunder. 
 (b)    Limitation of
Liability. Notwithstanding anything to the contrary in the Plan or any Award, none of the Company, nor any of its affiliates, nor the Administrator, nor any person acting on behalf of the Company, any of its affiliates, or the
Administrator, will be liable to any Participant, to any permitted transferee, to the estate or beneficiary of any Participant or any permitted transferee, or to any other person by reason of any acceleration of income, any additional

  
 10 

 
tax, or any penalty, interest or other liability asserted by reason of the failure of an Award to satisfy the requirements of Section 422 or Section 409A or by reason of
Section 4999 of the Code, or otherwise asserted with respect to any Award. 
 (c)    Unfunded
Plan. The Company’s obligations under the Plan are unfunded, and no Participant will have any right to specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with
respect to any amounts due or payable under the Plan. 
  

	12.	 ESTABLISHMENT OF SUB-PLANS 

The Administrator may at any time and from time to time (including before or after an Award is granted) establish, adopt, or revise any rules
and regulations as it may deem necessary or advisable to administer the Plan for Participants based outside of the U.S. and/or subject to the laws of countries other than the U.S., including by establishing one or more
sub-plans, supplements or appendices under the Plan or any Award agreement for the purpose of complying or facilitating compliance with non-U.S. laws or taking advantage
of tax favorable treatment or for any other legal or administrative reason determined by the Administrator. Any such sub-plan, supplement or appendix may contain, in each case, (i) such limitations on the
Administrator’s discretion under the Plan and (ii) such additional or different terms and conditions, as the Administrator deems necessary or desirable and will be deemed to be part of the Plan but will apply only to Participants within
the group to which the sub-plan, supplement or appendix applies (as determined by the Administrator); provided, however, that no sub-plan, supplement or appendix,
rule or regulation established pursuant to this provision shall increase the Share Pool. 
  

	13.	 GOVERNING LAW 

(a)    Certain Requirements of Corporate Law. Awards and shares of Stock will be granted,
issued and administered consistent with the requirements of applicable Delaware law relating to the issuance of stock and the consideration to be received therefor, and with the applicable requirements of the stock exchanges or other trading systems
on which the Stock is listed or entered for trading, in each case, as determined by the Administrator.

(subject to Section 409A) upon a termination or cessation of Employment, references to termination or cessation of employment, separation from service, retirement or similar or correlative terms will be construed to require a “separation

Section 422.

loss and may be applied to a Participant individually, or to a business unit or division of the Company or to the Company as a whole. A Performance Criterion may also be based on individual performance and/or subjective performance criteria (or any
