 3. Stock Subject to the Plan. 

(a) Stock Subject to the Plan. Subject to the provisions of Section 18 of the Plan, the maximum aggregate
number of Shares that may be awarded and sold under the Plan is 13,283,379 Shares (3,300,000 Shares plus 9,983,379 Shares which is the number of Shares that had been reserved but not issued under the

  

 A-3 

 
Company’s 2001 Stock Incentive Plan (the “2001 Plan”) as of March 28, 2005), plus up to an aggregate of 5,000,000 Shares that are or would have been returned to the 2001
Plan as a result of termination of options or repurchase of Shares on or after March 28, 2005. The Shares may be authorized, but unissued, or reacquired Common Stock. 

(b) Full Value Awards. Any Shares subject to Options or SARs will be counted against the
numerical limits of this Section 3 as one Share for every Share subject thereto. Any Shares subject to Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units with a per share or unit purchase price lower than 100% of
Fair Market Value on the date of grant will be counted against the numerical limits of this Section 3 as one and one-half (1 1/
2) Shares for every one (1) Share subject thereto. To the extent that a Share that was subject to an Award that counted as one and one-half
(1 1/2) Shares against the Plan reserve pursuant to
the preceding sentence is recycled back into the Plan under the next paragraph of this Section 3, the Plan will be credited with one and one-half
(1 1/2) Shares. 

(c) Lapsed Awards. If an Award expires or becomes unexercisable without having been exercised in full or, with
respect to an Award of Restricted Stock Units, Performance Units or Performance Shares, is terminated due to failure to vest, the unpurchased Shares (or for Awards other than Options or SARs, the unissued Shares) which were subject thereto will
become available for future grant or sale under the Plan (unless the Plan has terminated). Upon the exercise of a SAR settled in Shares, the gross number of Shares covered by the portion of the Award so exercised will cease to be available under the
Plan. 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 failure to vest, such Shares will become available for future grant under the Plan. Shares used
to pay the exercise or purchase price of an Award and/or to satisfy the tax withholding obligations related to an Award will not 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 18, 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 under this Section 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. 
 (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 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. 
  

 A-4 

 (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; 

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

(vii) 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 or for qualifying for favorable tax treatment under applicable foreign laws; 

(viii) to modify or amend each Award (subject to Section 23(c) of the Plan) including, without limitation, the
discretionary authority to extend the post-termination exercisability period of Awards longer than is otherwise provided for in the Plan. Notwithstanding the previous sentence, the Administrator may not modify or amend an Option or SAR to reduce the
exercise price of such Option or SAR after it has been granted (except for adjustments made pursuant to Section 18) nor may the Administrator cancel any outstanding Option or SAR and replace it with a new Option or SAR with a lower exercise
price, unless, in either case, such action is approved by the Company’s stockholders; 
 (ix) to allow
Participants to satisfy withholding tax obligations in such manner as prescribed in Section 19; 
 (x) 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; 

(xi) 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 pursuant to such procedures as the Administrator may determine; 
 (xii)
to grant in addition to the incentives described in Sections 6, 7, 8, 9, and 10 below, other incentives payable in cash or Shares under the Plan as determined by the Administrator to be in the best interests of the Company and subject to any terms
and conditions the Administrator deems advisable; and 
 (xiii) 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. 

(d) No Liability. Under no circumstances will the Company, its Affiliates, the Administrator, or the Board incur
liability for any indirect, incidental, consequential or special damages (including lost profits) of any form incurred by any person, whether or not foreseeable and regardless of the form of the act in which such a claim may be brought, with respect
to the Plan or the Company’s, its Affiliates’, the Administrator’s or the Board’s roles in connection with the Plan. 
  

 A-5 

 5. Eligibility. Nonstatutory Stock Options, Restricted Stock, Stock Appreciation
Rights, Restricted Stock Units, Performance Units, Performance Shares and such other cash or stock awards as the Administrator determines may be granted to Service Providers. Incentive Stock Options may be granted only to Employees of the Company or
any Parent or Subsidiary of the Company. 
 6. Stock Options. Subject to the terms and conditions of the Plan, an Option
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. 

(a) Limitations. 

(i) 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(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. 

(ii) The following limitations will apply to grants of Options: 

(1) No Service Provider will be granted, in any Fiscal Year, Options or SARs to purchase more than 1,000,000 Shares.

 (2) In connection with his or her initial service, a Service Provider may be granted Options or SARs to
purchase up to an additional 1,000,000 Shares, which will not count against the limit set forth in Section 6(a)(ii)(1) above. 

(3) The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s
capitalization as described in Section 18. 
 (4) If an Option or SAR is cancelled in the same Fiscal Year
in which it was granted (other than in connection with a transaction described in Section 18), the cancelled Option or SAR, as applicable, will be counted against the limits set forth in subsections (1) and (2) above. For this
purpose, if the exercise price of an Option or SAR is reduced, the transaction will be treated as a cancellation of the Option or SAR, as applicable, and the grant of a new Option or SAR, as applicable. 

(b) Term of Option. The term of each Option will be seven (7) 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. Moreover, 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. 
 (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 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 100% of the Fair Market Value per Share on the date of grant. 
  

 A-6 

 (2) In the case of a Nonstatutory Stock Option, the per Share exercise
price will be determined by the Administrator, but will be no less than 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 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) Option Agreement. Each Option grant will be evidenced by an Award Agreement that will specify the exercise
price, the term of the Option, the acceptable forms of consideration for exercise (which may include any form of consideration permitted by Section 6(c)(iv), the conditions of exercise, and such other terms and conditions as the Administrator,
in its sole discretion, will determine. 
 (iv) Form of Consideration. The Administrator will determine
the acceptable form(s) of consideration for exercising an Option, including the method of payment, to the extent permitted by Applicable Laws. 

(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 specifies 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 withholdings). Full payment may consist
of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. 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 18 of the Plan. 
 (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 a result of the Participant’s death, Disability or Misconduct, 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.

  

 A-7 

 (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. Notwithstanding the foregoing sentence, for Restricted Stock intended to qualify as
“performance-based compensation” within the meaning of Section 162(m) of the Code, during any Fiscal Year no Participant will receive more than an aggregate of 500,000 Shares of Restricted Stock; provided, however, that in connection
with a Participant’s initial service as an Employee, for Restricted Stock intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, an Employee may be granted an aggregate of up to
an additional 500,000 Shares of Restricted Stock. The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s capitalization as described in Section 18. Unless the Administrator determines
otherwise, Shares of Restricted Stock will be held by the Company as escrow agent 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. The restrictions
will lapse at a rate determined by the Administrator; provided, however, that Shares of Restricted Stock will vest no earlier than one-third (1/3rd) of the total number Shares of Restricted Stock subject to an Award each year from the date of
grant, unless the Administrator determines that the Award is to vest upon the achievement of a performance objective, provided the period for measuring performance will be at least twelve months. After the grant of Restricted Stock, the
Administrator, in its sole discretion, may reduce or waive any restrictions for such Restricted Stock upon or in connection with a Change in Control or upon or in connection with a Participant’s termination of service, including, without
limitation, due to death or Disability. 
 (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. 
  

 A-8 

 (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.
Stock Appreciation Rights. 
 (a) Grant of SARs. Subject to the terms and conditions of the Plan, a
SAR 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 SARs granted to
any Participant, provided that during any Fiscal Year, no Participant will be granted SARs or Options covering more than 1,000,000 Shares. Notwithstanding the foregoing limitation, in connection with a Participant’s initial service as an
Employee, an Employee may be granted SARs or Options covering up to an additional 1,000,000 Shares. The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s capitalization as described in
Section 18. 
 (c) Exercise Price and Other Terms. The Administrator, subject to the provisions of
the Plan, will have complete discretion to determine the terms and conditions of SARs granted under the Plan, provided, however, that the exercise price will be not less than one hundred percent (100%) of the Fair Market Value of a Share on the
date of grant. Notwithstanding the foregoing provisions of this Section 8(c), Stock Appreciation Rights 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 and the Treasury Regulations thereunder. 

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

(e) Expiration of SARs. A SAR granted under the Plan will expire upon the date determined by the Administrator, in
its sole discretion, and set forth in the Award Agreement; provided, however, that the term will be no more than seven (7) years from the date of grant thereof. Notwithstanding the foregoing, the rules of Section 6(d) also will apply to
SARs. 
 (f) Payment of SAR Amount. Upon exercise of a SAR, 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 SAR is exercised. 
 At the discretion of the Administrator, the payment upon SAR exercise may be in cash, in Shares of equivalent
value, or in some combination thereof. 
 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. Notwithstanding anything to the contrary in this subsection (a), for Restricted Stock Units intended to qualify as “performance-based compensation” 

 

 A-9 

 
within the meaning of Section 162(m) of the Code, during any Fiscal Year of the Company, no Participant will receive more than an aggregate of 500,000 Restricted Stock Units. Notwithstanding
the limitation in the previous sentence, for Restricted Stock Units intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, in connection with his or her initial service as an
Employee, an Employee may be granted an aggregate of up to an additional 500,000 Restricted Stock Units. The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s capitalization as described in
Section 18. 
 (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; provided, however, that Awards of Restricted Stock Units (other than any
Awards granted to Outside Directors) will vest no earlier than one-third (1/3) of the total number of units subject to such Award each year from the date of grant, unless the Administrator determines that the Award is to vest upon the
achievement of a performance objective, provided the period for measuring performance will be at least twelve months. 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 and may accelerate the time at which any restrictions will lapse or be removed. 
 (d) Form
and Timing of Payment. Payment of earned Restricted Stock Units will be made as soon as practicable after the date(s) set forth in the Award Agreement or as otherwise provided in the applicable Award Agreement or as required by Applicable Laws.
The Administrator, in its sole discretion, may pay earned Restricted Stock Units in cash, Shares, or a combination thereof. Shares represented by Restricted Stock Units that are fully paid in cash again will not reduce the number of Shares available
for grant under the Plan. 
 (e) Cancellation. On the date set forth in the Award Agreement, all unearned
Restricted Stock Units will be forfeited to the Company. 
 (f) Section 162(m) Performance
Restrictions. For purposes of qualifying grants of Restricted Stock Units as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement
of Performance Goals. The Performance Goals will be set by the Administrator on or before the Determination Date. In granting Restricted Stock Units which are intended to qualify under Section 162(m) of the Code, the Administrator will follow
any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals). 

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/Shares granted to each Participant provided that
during any Fiscal Year, for Performance Units/Shares intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, (a) no Participant will receive Performance Units having an initial
value greater than $5,000,000, and (b) no Participant will receive more than 500,000 Performance Shares. Notwithstanding the foregoing limitation, for Performance Units/Shares intended to qualify as “performance-based compensation”
within the meaning of Section 162(m) of the Code, in connection with a Participant’s initial service as an Employee, an Employee may be granted up to an additional 500,000 Performance Shares. The foregoing limitations will be adjusted
proportionately in connection with any change in the Company’s capitalization as described in Section 18. 
  

 A-10 

 (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; provided, however, that Awards of Performance Units/Shares (other than any Awards granted to Outside Directors)
will vest no earlier than one-third (1/3) of the total number of units or Shares subject to such Award each year from the date of grant, unless the Administrator determines that the Award is to vest upon the achievement of a performance
objective, provided the period for measuring performance will be at least twelve months. The Administrator may set performance objectives based on 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 upon or in connection with a Change in Control or upon or in connection with a Participant’s termination of service, including, without limitation,
due to death or Disability. 
 (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, or as otherwise provided in the applicable Award Agreement or as required by Applicable Laws. 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. 

(g) Section 162(m) Performance Restrictions. For purposes of qualifying grants of Performance Units/Shares as
“performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals will be set by the Administrator on
or before the Determination Date. In granting Performance Units/Shares which are intended to qualify under Section 162(m) of the Code, the Administrator will follow any procedures determined by it from time to time to be necessary or
appropriate to ensure qualification of the Award under Section 162(m) of the Code (e.g., in determining the Performance Goals). 

11. Other Cash or Stock Awards. In addition to the incentives described in Sections 6 through 10 above, the Administrator may
grant other incentives payable in cash or Shares under the Plan as it determines to be in the best interests of the Company and subject to such other terms and conditions as it deems appropriate, provided that in any Fiscal Year, a Participant will
not receive a cash Award under this Section in excess of $5,000,000. 
 12. Performance-Based Compensation Under Code
Section 162(m). 
 (a) General. If the Administrator, in its discretion, decides to grant an
Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the provisions of this Section 12 will 

 

 A-11 

 
control over any contrary provision in the Plan; provided, however, that the Administrator may in its discretion grant Awards that are not intended to qualify as “performance-based
compensation” under Section 162(m) of the Code to such Participants that are based on Performance Goals or other specific criteria or goals but that do not satisfy the requirements of this Section 12. 

(b) Performance Goals. The granting and/or vesting of Awards of Restricted Stock, Restricted Stock Units,
Performance Shares and Performance Units and other incentives under the Plan may be made subject to the attainment of performance goals relating to one or more business criteria within the meaning of Section 162(m) of the Code and may provide
for a targeted level or levels of achievement (“Performance Goals”) including cash flow; cash position; earnings before interest and taxes; earnings before interest, taxes, depreciation and amortization; earnings per Share; economic
profit; economic value added; equity or stockholder’s equity; market share; net income; net profit; net sales; operating earnings; operating income; profit before tax; ratio of debt to debt plus equity; ratio of operating earnings to capital
spending; return on net assets; revenue; sales growth; Share price; or total return to stockholders. Any Performance Goals may be used to measure the performance of the Company as a whole or a business unit or other segment of the Company, or one or
more product lines or specific markets and may be measured on a growth basis or relative basis to a peer group or index. The Performance Goals for a Participant will be determined by the Administrator based on the Company’s tactical and
strategic business objectives, which may differ from Participant to Participant and from Award to Award. Prior to the Determination Date, the Administrator will determine whether to make any adjustments to the calculation of any Performance Goal
with respect to any Participant for any significant or extraordinary events affecting the Company. In all other respects, Performance Goals will be calculated in accordance with the Company’s financial statements, generally accepted accounting
principles, or under a methodology established by the Administrator prior to the issuance of an Award, which is consistently applied and identified in the financial statements, including footnotes, or the management discussion and analysis section
of the Company’s annual report. 
 (c) Procedures. To the extent necessary to comply with the
performance-based compensation provisions of Section 162(m) of the Code, with respect to any Award granted subject to Performance Goals and intended to qualify as “performance-based compensation” under Section 162(m) of the Code,
on or before the Determination Date (i.e., within the first twenty-five percent (25%) of the Performance Period, but in no event more than ninety (90) days following the commencement of any Performance Period or such other time as may be
required or permitted by Section 162(m) of the Code), the Administrator will, in writing, (i) designate one or more Participants to whom an Award will be made, (ii) select the Performance Goals applicable to the Performance Period,
(iii) establish the Performance Goals, and amounts of such Awards, as applicable, which may be earned for such Performance Period, and (iv) specify the relationship between Performance Goals and the amounts of such Awards, as applicable,
to be earned by each Participant for such Performance Period. 
 (d) Additional Limitations.
Notwithstanding any other provision of the Plan, any Award which is granted to a Participant and is intended to constitute qualified performance-based compensation under Section 162(m) of the Code will be subject to any additional limitations
set forth in the Code (including any amendment to Section 162(m)) or any regulations and ruling issued thereunder that are requirements for qualification as qualified performance-based compensation as described in Section 162(m) of the
Code, and the Plan will be deemed amended to the extent necessary to conform to such requirements. 
 (e)
Determination of Amounts Earned. Following the completion of each Performance Period, the Administrator will certify in writing whether the applicable Performance Goals have been achieved for such Performance Period. A Participant will be
eligible to receive payment pursuant to an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code for a Performance Period only if the Performance Goals for such period are achieved. In
determining the amounts earned by a Participant pursuant to an Award intended to qualified as “performance-based compensation” under Section 162(m) of the Code, the Committee will have the right to (a) reduce or eliminate (but
not to increase) the amount payable at a given level of performance to take into account additional factors that the Committee may deem relevant to the assessment of individual or corporate performance for the

  

 A-12 

 
Performance Period, (b) determine what actual Award, if any, will be paid in the event of a termination of employment as the result of a Participant’s death or disability or upon a
Change in Control or in the event of a termination of employment following a Change in Control prior to the end of the Performance Period, and (c) determine what actual Award, if any, will be paid in the event of a termination of employment
other than as the result of a Participant’s death or disability prior to a Change of Control and prior to the end of the Performance Period to the extent an actual Award would have otherwise been achieved had the Participant remained employed
through the end of the Performance Period. A Participant will be eligible to receive payment pursuant to an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code for a Performance Period only
if the Performance Goals for such period are achieved. 
 13. 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 of Awards 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. 
 14. Leaves of Absence/Transfer Between
Locations. Unless the Administrator provides otherwise and except as required by Applicable Laws, 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 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. 

15. Transferability of Awards. 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. 
 16.
Termination of Relationship as a Service Provider due to Misconduct. If a Participant ceases to be a Service Provider due to his or her Misconduct or should a Participant engage in Misconduct while holding an outstanding Award, then all
Awards that the Participant then holds will immediately terminate and the Participant will have no further rights with respect to such Awards. Upon such a termination, the Shares covered by the Awards that so terminate will revert to the Plan.

 17. Awards to Outside Directors. 

(a) General. Outside Directors will be entitled to receive all types of Awards under this Plan, including
discretionary Awards not covered under this Section 17. All grants of Options and Restricted Stock Units to Outside Directors pursuant to this Section will be automatic and nondiscretionary, except as otherwise provided herein, and will be made
in accordance with the following provisions: 
  

 A-13 

 (b) Options. 

(i) First Option. Each Outside Director who becomes an Outside Director after March 7, 2007 will be
automatically granted a Nonstatutory Stock Option to purchase 30,000 Shares (the “First Option”) on the date on which such person first becomes an Outside Director, whether through election by the stockholders of the Company or appointment
by the Board to fill a vacancy; provided, however, that an Inside Director who ceases to be an Inside Director but who remains a Director will not receive a First Option. 

(ii) Subsequent Option. Each Outside Director will be automatically granted a Nonstatutory Stock Option to purchase
10,000 Shares (a “Subsequent Option”) on the date of each annual meeting of the Company’s stockholders following March 7, 2007; provided that he or she is then an Outside Director and, provided further, that as of
such date, he or she will have served on the Board for at least the preceding six (6) months. 
 (iii)
Terms of Options. The terms of First Options and Subsequent Options granted hereunder will be as follows: 

(1) the term of each Option will be seven (7) years. 

(2) the exercise price per Share will be 100% of the Fair Market Value per Share on the date of grant. 

(3) twenty-five percent (25%) of the Shares subject to each First Option will vest on each anniversary of the date
of grant of such Option, so that 100% of the Shares subject to such Option will be vested four (4) years from the grant date, subject to Optionee continuing to be a Director through such dates. One hundred percent (100%) of the Shares
subject to each Subsequent Option will vest on the earlier of (i) the one-year anniversary of the date of grant and (ii) the date of the next annual meeting of the Company’s stockholders following the date of grant, subject to the
Optionee continuing to be a Director through such date. 
 (4) each Option granted under this Section 17
will have such other terms and conditions as the Administrator determines. 
 (c) Restricted Stock Units.

 (i) Annual Restricted Stock Units. Each Outside Director will be automatically granted an Award of 3,000 Restricted
Stock Units (“Annual Restricted Stock Units”) on the date of each annual meeting of the Company’s stockholders following March 7, 2007; provided that he or she is then an Outside Director and, provided further, that
as of such date, he or she will have served on the Board for at least the preceding six (6) months. 
 (ii)
Terms of Restricted Stock Units. The terms of Annual Restricted Stock Units granted hereunder will be as follows: 

(1) one hundred percent (100%) of the Annual Restricted Stock Units will vest on the earlier of (i) the
one-year anniversary of the date of grant and (ii) the date of the next annual meeting of the Company’s stockholders following the date of grant, subject to the Optionee continuing to be a Director through such date. 

(2) each Restricted Stock Unit will represent the right to receive a Share and will be settled in Common Stock upon
vesting. 
 (3) Awards of Restricted Stock Units granted under this Section 17 will have such other terms
and conditions as the Administrator determines. 
 (d) Adjustments. The Administrator in its discretion
may change and otherwise revise the terms of Awards granted under this Section 17, including, without limitation, the number of Shares, exercise prices and other terms thereof, for Awards granted on or after the date the Administrator
determines to make any such change or revision. 
  

 A-14 

 18. 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 that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award, and the numerical Share and unit limits set forth in Sections 3, 6, 7, 8, 9, 10 and 17. 

(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 Change in Control, each outstanding Award
will be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. 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 that are not assumed or substituted for, including Shares as to which such Awards would not otherwise be
vested or exercisable, all restrictions on Restricted Stock, Restricted Stock Units, and Performance Shares/Units not assumed or substituted for will lapse, and, with respect to Awards with performance-based vesting not assumed or substituted for,
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
for 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 fully vested and 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. 

With respect to Awards granted to Outside Directors 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, 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 subject thereto, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock, Restricted
Stock Units, Performance Shares and Performance 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. 
 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)
or, in the case of a Stock Appreciation Right upon the exercise of which the Administrator determines to pay cash or a Restricted Stock Unit, Performance Share or Performance Unit which the Administrator can determine to pay in cash, the fair market
value of the consideration 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 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 Share or Performance Unit, for each Share subject to
such Award (or in the case of 
  

 A-15 

 
an Award settled in cash, the number of implied shares determined by dividing the value of the Award by the per share consideration received by holders of Common Stock in the Change in Control),
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 18(c) to the contrary, an Award that vests, is earned or paid-out upon the
satisfaction of one or more performance objectives (including any Performance Goals) will not be considered assumed if the Company or its successor modifies any of such performance objectives without the Participant’s consent; provided,
however, a modification to such performance objectives only to reflect the successor corporation’s post-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption. 

Notwithstanding anything in this Section 18(c) to the contrary, if a payment under an Award Agreement is subject to
Section 409A of the Code and if the change in control definition contained in the Award Agreement or other agreement related to the Award does not comply with the definition of “change in control” for purposes of a distribution under
Section 409A of the Code, 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 Section 409A of the Code without triggering any
penalties applicable under Section 409A of the Code. 
 19. 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 amount required to be withheld, (c) delivering to the Company already-owned Shares having a Fair
Market Value equal to the amount required to be withheld, provided the delivery of such Shares will not result in any adverse accounting consequences as the Administrator determines in its sole discretion, (d) 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 (e) retaining from salary or
other amounts payable to the Participant cash having a sufficient value to satisfy the amount required to be withheld. 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 to the Award on the date that the amount of tax to be withheld is to
be determined. 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. 

20. 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. 
 21. 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. 
  

 A-16 

 22. Term of Plan. Subject to Section 26 of the Plan, this Plan as adopted by the
Board in its amended and restated form will become effective as of the date of the Company’s 2010 Annual Meeting of Stockholders and will continue in effect for a term ending on the ten (10) year anniversary of such meeting, unless
terminated earlier under Section 23 of the Plan. 
 23. 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. Without limiting the foregoing sentence, the number of Shares available under the Plan pursuant to Section 3 herein may not be increased without approval of the Company’s
stockholders, except as provided in Section 3. 
 (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. 

24. 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. 
 25. 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. 
 26. 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 manner and to the degree required under
Applicable Laws. 
  

 A-172010 Employee Stock Purchase Plan

 Exhibit 4.2 

ALIGN TECHNOLOGY, INC. 

2010 EMPLOYEE STOCK PURCHASE PLAN 

1. Purpose. The purpose of the Plan is to provide employees of the Company and its Designated Subsidiaries with an opportunity to

 2. purchase Common Stock through accumulated Contributions (as defined in Section 2(j) below). The Company’s
intention is to have Plan qualify as an “employee stock purchase plan” under Section 423 of the Code. The provisions of the Plan, accordingly, will be construed so as to extend and limit Plan participation in a uniform and
nondiscriminatory basis consistent with the requirements of Section 423 of the Code. 
 3. Definitions. 

(a) “Administrator” means the Board or any Committee designated by the Board to administer the Plan
pursuant to Section 14. 
 (b) “Applicable Laws” means the requirements relating to the
administration of equity-based awards under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed or quoted and the applicable laws of any foreign
country or jurisdiction where options are, or will be, granted under the Plan. 
 (c) “Board”
means the Board of Directors of the Company. 
 (d) “Change in Control” means the occurrence of
any of the following events: 
 (i) Change in Ownership of the Company. A change in the ownership of the
Company which occurs on the date that any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than 50%
of the total voting power of the stock of the Company; or 
 (ii) Change in Effective Control of the
Company. If the Company has a class of securities registered pursuant to Section 12 of the Exchange Act, a change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during
any 12 month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause (ii), if any Person is considered to be in
effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(iii) Change in Ownership of a Substantial Portion of the Company’s Assets. A change in the ownership of a
substantial portion of the Company’s assets which occurs on the date that any Person acquires (or has acquired during the 12 month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that
have a total gross fair market value equal to or more than 50% of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions. For purposes of this subsection (iii), gross fair market
value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 

For purposes of this Section 2(d), persons will be considered to be acting as a group if they are owners of a
corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 

Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a
change in control event within the meaning of Code Section 409A, as it has been and may be amended from time to time, and any proposed or final Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be
promulgated thereunder from time to time.

 4. Eligibility. 

(a) Offering Periods. Any Eligible Employee on a given Enrollment Date will be eligible to participate in the Plan,
subject to the requirements of Section 5. Employees who are citizens or residents of a non-U.S. jurisdiction may be excluded from participation in the Plan or an Offering if the participation of such Employees is prohibited under the laws of
the applicable jurisdiction or if complying with the laws of the applicable jurisdiction would cause the Plan or an Offering to violate Section 423 of the Code. 

(b) Limitations. Any provisions of the Plan to the contrary notwithstanding, no Eligible Employee will be granted
an option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital
stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the
Company or of any Parent or Subsidiary of the Company, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans (as defined in Section 423 of the Code) of the Company or any Parent or
Subsidiary of the Company accrues at a rate, which exceeds twenty-five thousand dollars ($25,000) worth of stock (determined at the Fair Market Value of the stock at the time such option is granted) for each calendar year in which such option is
outstanding at any time, as determined in accordance with Section 423 of the Code and the regulations thereunder. 
 5.
Offering Periods. The Plan will be implemented by consecutive, overlapping Offering Periods with a new Offering Period commencing on the first Trading Day on or after February 1 and August 1 each year, or on such other date as the
Administrator will determine. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to future offerings without stockholder approval if such change is announced prior
to the scheduled beginning of the first Offering Period to be affected thereafter. 
 6. Participation. An Eligible
Employee may participate in the Plan by (i) submitting to the Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to an applicable Enrollment Date, a properly completed
subscription agreement authorizing Contributions in the form provided by the Administrator for such purpose, or (ii) following an electronic or other enrollment procedure determined by the Administrator. 

7. Contributions. 

(a) At the time a Participant enrolls in the Plan pursuant to Section 5, he or she will elect to have payroll
deductions made on each pay day or other Contributions (to the extent permitted by the Administrator) made during the Offering Period in an amount not less than one percent (1%) and not exceeding fifteen percent (15%) of the Compensation,
which he or she receives on each pay day during the Offering Period; provided, however, that should a pay day occur on an Exercise Date, a Participant will have any payroll deductions made on such day applied to his or her account under the
subsequent Purchase Period or Offering Period. The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the
subscription agreement prior to each Exercise Date of each Purchase Period, provided that payment through means other than payroll deductions shall be permitted only if the Participant has not already had the maximum permitted amount withheld
through payroll deductions during the Purchase Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof. 

(b) Payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on
the last pay day prior to the Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 10 hereof. 

 

 B-4 

 (c) All Contributions made for a Participant will be credited to his or her
account under the Plan and payroll deductions will be made in whole percentages only. A Participant may not make any additional payments into such account. 

(d) A Participant may discontinue his or her participation in the Plan as provided in Section 10, or may increase or
decrease the rate of his or her Contributions during the Offering Period by (i) properly completing and submitting to the Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to
an applicable Exercise Date, a new subscription agreement authorizing the change in Contribution rate in the form provided by the Administrator for such purpose, or (ii) following an electronic or other procedure prescribed by the
Administrator; provided, however, that a Participant may only make one Contribution change during each month of the Offering Period and, provided, further, that unless the Administrator provides otherwise, a Participant may reduce, but not increase,
his or her Contribution rate during a Purchase Period for that Purchase Period (it being understood that a Participant may increase his or her Contribution rate for a future Purchase Period prior to the commencement of any such Purchase Period). If
a Participant has not followed such procedures to change the rate of Contributions, the rate of his or her Contributions will continue at the originally elected rate throughout the Offering Period and future Offering Periods (unless terminated as
provided in Section 10). The Administrator may, in its sole discretion, limit the nature and/or number of Contribution rate changes that may be made by Participants during any Offering Period, and may establish such other conditions or
limitations as it deems appropriate for Plan administration. Any change in payroll deduction rate made pursuant to this Section 6(d) will be effective as of the first full payroll period following five (5) business days after the date on
which the change is made by the Participant (unless the Administrator, in its sole discretion, elects to process a given change in payroll deduction rate more quickly). 

(e) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and
Section 3(b), a Participant’s Contributions may be decreased to zero percent (0%) at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 3(b) hereof, Contributions will recommence at the rate
originally elected by the Participant effective as of the beginning of the first Purchase Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10. 

(f) Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Eligible Employees to
participate in the Plan via cash contributions instead of payroll deductions if (i) payroll deductions are not permitted under applicable local law, and (ii) the Administrator determines that cash contributions are permissible under
Section 423 of the Code. 
 (g) At the time the option is exercised, in whole or in part, or at the time
some or all of the Common Stock issued under the Plan is disposed of (or any other time that a taxable event related to the Plan occurs), the Participant must make adequate provision for the Company’s or Employer’s federal, state, local or
any other tax liability payable to any authority including taxes imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding obligations, if any, which arise upon the exercise of the option or the
disposition of the Common Stock (or any other time that a taxable event related to the Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s Compensation the amount necessary
for the Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to sale or early disposition of Common Stock
by the Eligible Employee. In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or any other method of withholding the Company or the Employer deems appropriate to the
extent permitted by U.S. Treasury Regulation Section 1.423-2(f). 
 8. Grant of Option. On the Enrollment Date of
each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock
determined by dividing such Eligible Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible 

 

 B-5 

 
Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that (a) in no event will an Eligible Employee be permitted to purchase during each Purchase Period
more than 2,500 shares of the Company’s Common Stock (subject to the limitations set forth in Section 3(b)) on the Enrollment Date, (b) in no event will the number of shares of the Company’s Common Stock that may be purchased
during each Purchase Period under the Plan exceed 400,000 shares, and (c) such limits under clauses (a) and (b) further will be subject to the limitations set forth in Section 13 and to any adjustment pursuant to Section 19.
The Eligible Employee may accept the grant of such option with respect to an Offering Period by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase
or decrease, in its absolute discretion, the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Purchase Period of an Offering Period. Exercise of the option will occur as provided in Section 8, unless
the Participant has withdrawn pursuant to Section 10. The option will expire on the last day of the Offering Period. 
 9.
Exercise of Option. 
 (a) Unless a Participant withdraws from the Plan as provided in Section 10,
his or her option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares subject to the option will be purchased for such Participant at the applicable Purchase Price
with the accumulated Contributions from his or her account. No fractional shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be retained in
the Participant’s account for the subsequent Purchase Period or Offering Period, subject to earlier withdrawal by the Participant as provided in Section 10. Any other funds left over in a Participant’s account after the Exercise Date
will be returned to the Participant. During a Participant’s lifetime, a Participant’s option to purchase shares hereunder is exercisable only by him or her. 

(b) If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to
which options are to be exercised may exceed (i) the number of shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock
available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or
Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all
Offering Periods then in effect or (y) provide that the Company will make a pro rata allocation of the shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as
it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 20. The Company may
make a pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s
stockholders subsequent to such Enrollment Date. 
 10. Delivery. As soon as reasonably practicable after each Exercise
Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant the shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and
pursuant to rules established by the Administrator. The Company may permit or require that shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or
automated methods of share transfer. The Company may require that shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. No
Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the Participant as provided in this
Section 9. 
  

 B-6 

 11. Withdrawal. 

(a) A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used
to exercise his or her option under the Plan at any time by (i) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose, or
(ii) following an electronic or other withdrawal procedure determined by the Administrator. All of the Participant’s Contributions credited to his or her account will be paid to such Participant promptly after receipt of notice of
withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of shares will be made for such Offering Period. If a Participant withdraws from an Offering
Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of Section 5. 

(b) A Participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to
participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws. 

12. Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be
deemed to have elected to withdraw from the Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the Plan will be returned to such Participant or,
in the case of his or her death, to the person or persons entitled thereto under Section 15, and such Participant’s option will be automatically terminated. 

13. Interest. No interest will accrue on the Contributions of a participant in the Plan, except as may be required by applicable
law, as determined by the Company, and if so required by the laws of a particular jurisdiction, shall apply to all Participants in the relevant Offering except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f).

 14. Stock. 

(a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum
number of shares of Common Stock that will be made available for sale under the Plan will be 2,400,000 shares of Common Stock. 

(b) 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), a Participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares.

 (c) Shares of Common Stock to be delivered to a Participant under the Plan will be registered in the name of
the Participant or in the name of the Participant and his or her spouse. 
 15. Administration. The Plan will be
administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of
the Plan, to designate separate Offerings under the Plan, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary for the administration of the Plan (including,
without limitation, to adopt such procedures and sub-plans as are necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S.). Unless otherwise determined by the
Administrator, the Employees eligible to participate in each sub-plan will participate in a separate Offering. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding
eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment

  

 B-7 

 
of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements,
withholding procedures and handling of stock certificates that vary with applicable local requirements. Every finding, decision and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all
parties. 
 16. Designation of Beneficiary. 

(a) If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any shares
of Common Stock and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such
shares and cash. In addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior
to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective. 

(b) Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined by the
Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company will deliver such shares and/or cash to the
executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one
or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 

(c) All beneficiary designations will be in such form and manner as the Administrator may designate from time to time.
Notwithstanding Sections 15(a) and (b) above, the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).

 17. Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the
exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof)
by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10
hereof. 
 18. Use of Funds. The Company may use all Contributions received or held by it under the Plan for any
corporate purpose, and the Company will not be obligated to segregate such Contributions except under Offerings in which applicable local law requires that Contributions to the Plan by Participants be segregated from the Company’s general
corporate funds and/or deposited with an independent third party for Participants in non-U.S. jurisdictions. Until shares of Common Stock are issued, Participants will only have the rights of an unsecured creditor with respect to such shares.

 19. Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be
given to participating Eligible Employees at least annually, which statements will set forth the amounts of Contributions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any. 

20. Adjustments, Dissolution, Liquidation, Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock,
other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common

  

 B-8 

 
Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per
share and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any
Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise
Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, at least ten (10) business days prior to the New Exercise Date, that the
Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from
the Offering Period as provided in Section 10 hereof. 
 (c) Merger or Change in Control. In the
event of a merger or Change in Control, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation
refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period shall end. The New Exercise Date will occur before the date
of the Company’s proposed merger or Change in Control. The Administrator will notify each Participant in writing or electronically prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the
New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 

21. Amendment or Termination. 

(a) The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time
and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next Exercise Date
(which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 19). If
the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without interest thereon,
except as otherwise required under local laws, as further set forth in Section 12 hereof) as soon as administratively practicable. 

(b) Without stockholder consent and without limiting Section 20(a), the Administrator will be entitled to change the
Offering Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit
payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods
and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator
determines in its sole discretion advisable that are consistent with the Plan. 
  

 B-9 

 (c) In the event the Administrator determines that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence
including, but not limited to: 
 (i) amending the Plan to conform with the safe harbor definition under
Statement of Financial Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time; 

(ii) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change
in Purchase Price; 
 (iii) shortening any Offering Period by setting a New Exercise Date, including an Offering
Period underway at the time of the Administrator action; 
 (iv) reducing the maximum percentage of Compensation
a Participant may elect to set aside as Contributions; and 
 (v) reducing the maximum number of Shares a
Participant may purchase during any Offering Period or Purchase Period. 
 Such modifications or amendments will not require stockholder
approval or the consent of any Plan Participants. 
 22. Notices. All notices or other communications by a Participant to
the Company under or in connection with the Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

23. Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of
such option and the issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and
regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance. 

As a condition to the exercise of an option, the Company may require the person exercising such option 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 by
any of the aforementioned applicable provisions of law. 
 24. Code Section 409A. The Plan is exempt from the
application of Code Section 409A. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Code Section 409A or
that any provision in the Plan would cause an option under the Plan to be subject to Code Section 409A, the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the
Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Code
Section 409A, but only to the extent any such amendments or action by the Administrator would not violate Code Section 409A. Notwithstanding the foregoing, the Company shall have no liability to a Participant or any other party if the
option to purchase Common Stock under the Plan that is intended to be exempt from or compliant with Code Section 409A is not so exempt or compliant or for any action taken by the Administrator with respect thereto. The Company makes no
representation that the option to purchase Common Stock under the Plan is compliant with Code Section 409A. 
 25.
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.

the laws of the State of California (except its choice-of-law provisions). 
 27. Severability. If any provision of the
Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability shall not affect the remaining parts of the Plan, and the Plan
shall be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.

Common Stock on any Exercise Date in an Offering Period is lower than the Fair Market Value of the Common Stock on the Enrollment Date of such Offering Period, then all participants in such Offering Period will be automatically withdrawn from such
Offering Period immediately after the exercise of their option on such Exercise Date and automatically re-enrolled in the immediately following Offering Period as of the first day thereof.
