	1.	Purposes of the Plan. 

 The purposes of this Plan are to attract and retain personnel for positions with
the Company, to provide additional incentive to Employees, Directors, and Consultants (collectively, “Service Providers”), and to promote the success of the Company’s business. 

The Plan permits the grant of Incentive Stock Options to Employees and the grant of Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock,
Restricted Stock Units, Performance Shares, Performance Stock Units, and Performance Awards to any Service Provider. 
  

	2.	Shares Subject to the Plan. 

 (a) Allocation of Shares to Plan. The maximum
aggregate number of Shares that may be issued under the Plan is: 
 (i) 30,000,000 Shares, plus 

(ii) a number of Shares equal to the number of shares of Class B common stock of the Company subject to outstanding awards granted under the
Square, Inc. 2009 Stock Plan that, after the Registration Date, expire or otherwise terminate without having been exercised in full and a number of Shares equal to the number of Shares of Class B common Stock of the Company issued under awards
granted under the Existing Plan that, after the Registration Date, are forfeited to the Company, tendered to or withheld by the Company for payment of an exercise price or for tax withholding, or repurchased by the Company due to failure to vest,
with the maximum number of Shares that may be added to the Plan under this Section 2(a)(i) being equal to 106,234,076 Shares, plus 

(iii) any additional Shares that become available for issuance under the Plan under Sections 2(b) and 2(c). 

The Shares may be authorized but unissued Common Stock or Common Stock issued and then reacquired by the Company. 

(b) Automatic Share Reserve Increase. The number of Shares available for issuance under the Plan will be increased on the first day of
each Fiscal Year beginning with the 2016 Fiscal Year, in an amount equal to the least of 
 (i) 40,000,000 Shares, 

(ii) 5 % of the total number of shares of all classes of the Company’s common stock outstanding on the last day of the immediately
preceding Fiscal Year, and 
 (iii) a lower number of Shares determined by the Administrator. 

(c) Lapsed Awards. 

(i) Options and Stock Appreciation Rights. If an Option or Stock Appreciation Right expires or becomes unexercisable without
having been exercised in full or is surrendered under an Exchange Program, the unissued Shares subject to the Option or Stock Appreciation Right will become available for future issuance under the Plan.  

(ii) Stock Appreciation Rights. Only Shares actually issued pursuant to a Stock Appreciation Right (i.e., the net Shares
issued) will cease to be available under the Plan; all remaining Shares originally subject to the Stock Appreciation Right will remain available for future issuance under the Plan.  

(iii) Full-Value Awards. Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares, Performance
Stock Units or stock-settled Performance Awards that are reacquired by the Company due to failure to vest or are forfeited to the Company will become available for future issuance under the Plan. 

  
 - 2 - 

 (iv) Withheld Shares. Shares used to pay the Exercise Price of an Award or to
satisfy tax withholding obligations related to an Award will become available for future issuance under the Plan.  
 (v)
Cash-Settled Awards. If any portion of an Award under the Plan is paid to a Participant in cash rather than Shares, that cash payment will not reduce the number of Shares available for issuance under the Plan.  

(d) Incentive Stock Options. The maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal
200% of the aggregate Share number stated in Section 2(a) plus, to the extent allowable under Code Section 422, any Shares that become available for issuance under the Plan under Sections 2(b) and 2(c). 

(e) Adjustment. The numbers provided in Sections 2(a), 2(b), and 2(d) will be adjusted as a result of changes in capitalization
referred to in Section 13. 
 (f) Substitute Awards. If the Committee grants Awards in substitution for equity compensation
awards outstanding under a plan maintained by an entity acquired by or consolidated with the Company, the grant of those substitute Awards will not decrease the number of Shares available for issuance under the Plan. 

 

	3.	Administration of the Plan. 

 (a) Procedure. 

(i) General. The Plan will be administered by the Board or a Committee (the “Administrator”). Different
Administrators may administer the Plan with respect to different groups of Service Providers. The Board may retain the authority to concurrently administer the Plan with a Committee and may revoke the delegation of some or all authority previously
delegated.  
 (ii) Further Delegation. To the extent permitted by Applicable Laws, the Board or a Committee may delegate to
1 or more Officers the authority to grant Awards to Employees of the Company or any of its Subsidiaries who are not Officers, provided that the delegation must specify any limitations on the authority required by Applicable Laws, including the
total number of Shares that may be subject to the Awards granted by such Officer(s). Such delegation may be revoked at any time by the Board or Committee. Any such Awards will be granted on the form of Award Agreement most recently approved for use
by the Board or a Committee made up solely of Directors, unless the resolutions delegating the authority permit the Officer(s) to use a different form of Award Agreement approved by the Board or a Committee made up solely of Directors. 

(iii) Section 162(m). Unless an Award is granted and administered solely by a Committee of 2 or more “outside
directors” within the meaning of Code Section 162(m), it will not qualify as “performance-based compensation” within the meaning of Code Section 162(m). 

(b) Powers of the Administrator. Subject to the terms of the Plan, any limitations on delegations specified by the Board, and any
requirements imposed by Applicable Laws, the Administrator will have the authority, in its sole discretion, to make any determinations and perform any actions deemed necessary or advisable to administer the Plan including: 

(i) to determine the Fair Market Value; 

(ii) to approve forms of Award Agreements for use under the Plan (provided that all forms of Award Agreement must be approved by the Board or
the Committee of Directors acting as the Administrator); 
 (iii) to select the Service Providers to whom Awards may be granted and grant
Awards to such Service Providers; 
 (iv) to determine the number of Shares to be covered by each Award granted; 

(v) to determine the terms and conditions, consistent with the Plan, of any Award granted. Such terms and conditions may include, but are not
limited to, the Exercise Price, the time(s) 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 to an Award; 

  
 - 3 - 

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

(vii) to interpret the Plan and make any decisions necessary to administer the Plan; 

(viii) to establish, amend and rescind rules relating to the Plan, including rules relating to sub-plans established to satisfy laws of
jurisdictions other than the United States or to qualify Awards for favorable tax treatment under laws of jurisdictions other than the United States; 

(ix) to interpret, modify or amend each Award (subject to Section 18), including extending the Expiration Date and the post-termination
exercisability period of such modified or amended Awards; 
 (x) to allow Participants to satisfy tax withholding obligations in any manner
permitted by Section 15; 
 (xi) to delegate ministerial duties to any of the Company’s employees; 

(xii) to authorize any person to take any steps and execute, on behalf of the Company, any documents required for an Award previously granted
by the Administrator to be effective; and 
 (xiii) to allow Participants to defer the receipt of the payment of cash or the delivery of
Shares otherwise due to any such Participants under an Award. 
 (c) Termination of Status. 

(i) Unless a Participant is on a leave of absence approved by the Company as set forth in Section 11, the Participant’s status as a
Service Provider will end at midnight at the end of the last day the Participant actively provides services for a member of the Company Group (the “Termination of Status Date”). The Administrator has the sole discretion to determine the
date on which a Participant stops actively providing services and whether a Participant may still be considered to be providing services while on a leave of absence and the Administrator may delegate this decision, other than with respect to
Officers, to the Company’s senior human resources officer. 
 (ii) This termination of status as a Service Provider will occur
regardless of the reason for such termination even if the termination is later found to be invalid, in breach of employment laws in the jurisdiction where Participant is providing services, or in violation of the terms of Participant’s
employment or service agreement, if any such agreement exists. 
 (iii) Unless otherwise expressly provided in an Award Agreement or
otherwise determined by the Administrator, a Participant’s right to vest in any Award under the Plan will cease as of the Termination of Status Date and will not be extended by any notice period, whether arising under contract, statute or
common law, including any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is providing services. 

(d) Grant Date. The grant date of an Award (“Grant Date”) will be the date that the Administrator makes the determination
granting such Award or may be a later date if such later date is designated by the Administrator on the date of the determination or under an automatic grant policy. Notice of the determination will be provided to each Participant within a
reasonable time after the Grant Date. 
 (e) Waiver. The Administrator may waive any terms, conditions or restrictions. 

(f) Fractional Shares. Except as otherwise provided by the Administrator, any fractional Shares that result from the adjustment of
Awards will be canceled. Any fractional Shares that result from vesting percentages will be accumulated and vested on the date that an accumulated full Share is vested. 

(g) Electronic Delivery. The Company may deliver by e-mail or other electronic means (including posting on a website maintained by the
Company or by a third party under contract with the Company or another member of the Company Group) all documents relating to the Plan or any Award and all other documents that the Company is required to deliver to its security holders (including
prospectuses, annual reports and proxy statements). 

  
 - 4 - 

 (h) Choice of Law; Choice of Forum. The Plan, all Awards and all determinations made and
actions taken under the Plan, to the extent not otherwise governed by the laws of the United States, will be governed by the laws of the State of Delaware without giving effect to principles of conflicts of law. For purposes of litigating any
dispute that arises under this Plan, a Participant’s acceptance of an Award is his or her consent to the jurisdiction of the State of Delaware, and agreement that any such litigation will be conducted in Delaware Court of Chancery, or the
federal courts for the United States for the District of Delaware, and no other courts, regardless of where a Participant’s services are performed. 

(i) 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. 
  

	4.	Stock Options. 

 (a) Stock Option Award Agreement. Each Option will be evidenced
by an Award Agreement that will specify the number of Shares subject to the Option, its per share exercise price (“Exercise Price”), its Expiration Date, and such other terms and conditions as the Administrator determines. Each Option will
be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. An Option not designated as an Incentive Stock Option is a Nonstatutory Stock Option. 

(b) Exercise Price. The Exercise Price for the Shares to be issued upon exercise of an Option will be determined by the Administrator.

 (c) Form of Consideration. The Administrator will determine the acceptable forms of consideration for exercising an Option and
those forms of consideration will be described in the Award Agreement. The consideration may consist of any combination of the following, to the extent permitted by Applicable Laws: 

(i) cash; 
 (ii) check or wire
transfer; 
 (iii) promissory note; 

(iv) other Shares that have a fair market value on the date of surrender equal to the aggregate Exercise Price of the Shares as to which such
Option will be exercised. To the extent not prohibited by the Administrator, this shall include the ability to tender Shares to exercise the Option and then use the Shares received on exercise to exercise the Option with respect to additional
Shares; 
 (v) consideration received by the Company under a cashless exercise arrangement (whether through a broker or
otherwise) implemented by the Company for the exercise of Options that has been approved by the Board or a Committee of Directors; 

(vi) consideration received by the Company under a net exercise program under which Shares are withheld from otherwise deliverable Shares
that has been approved by the Board or a Committee of Directors; and 
 (vii) any other consideration or method of payment to issue Shares
(provided that other forms of considerations may only be approved by the Board or a Committee of Directors). 
 (d) Incentive Stock
Option Limitations. 
 (i) The Exercise Price of an Incentive Stock Option may not be less than 100% of the Fair Market Value on the
Grant Date. 
 (ii) To the extent that the aggregate fair market value of the shares with respect to which incentive stock options under
Code Section 422(b) are exercisable for the first time by a Participant during any calendar year (under all plans and agreements of the Company Group) exceeds $100,000, the incentive stock options whose value exceeds $100,000 will be
treated as nonstatutory stock options. Incentive stock options will be considered in the order in which they were granted. For this purpose the fair market value of the shares subject to an option will be determined as of the grant date of each
option. 
  

  
 - 5 - 

 (iii) The Expiration Date of an Incentive Stock Option will be the day prior to the 10th anniversary of the Grant Date or any earlier date provided in the Award Agreement, subject to clause (iv) below. 

(iv) The following rules apply to Incentive Stock Options granted to Participants who own stock representing more than 10% of the total
combined voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company: 
 (1) the Expiration Date of the
Incentive Stock Option may not be after the day prior to the 5th anniversary of the Grant Date; and 

(2) the Exercise Price may not be less than 110% of the Fair Market Value on the Grant Date. 

If an Option is designated in the Administrator action that granted it as an Incentive Stock Option but the terms of the Option do not comply with Sections
4(d)(iv)(1) and 4(d)(iv)(2), then the Option will not qualify as an Incentive Stock Option. All Options granted under the Plan are Nonstatutory Stock Options unless specifically designated as Incentive Stock Options in the Award Agreement pursuant
to which such Options are granted. 
 (e) Exercise of Option. An Option is exercised when the Company receives: (i) a notice of
exercise (in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding
taxes). Shares issued upon exercise of an Option will be issued in the name of the Participant. Until the Shares are issued (as evidenced by the entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to
vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, despite the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is
exercised. An Option may not be exercised for a fraction of a Share. Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for purchase under the Option, by the number of Shares
as to which the Option is exercised. 
 (f) Expiration of Options. Subject to Section 4(d), an Option’s Expiration Date
will be set forth in the Award Agreement. An Option may expire before its expiration date under Sections 14 or 16(b) or under the Award Agreement. 

(g) Tolling of Expiration. If exercising an Option prior to its expiration is not permitted because of Applicable Laws, other than the
rules of any stock exchange or quotation system on which the Common Stock is listed or quoted, the Option will remain exercisable until 30 days after the first date on which exercise would no longer be prevented by such provisions. If this would
result in the Option remaining exercisable past its Expiration Date, then it will remain exercisable only until the end of the later of (x) the first day on which its exercise would not be prevented by Section 19(a) and (y) its
Expiration Date. 
  

	5.	Restricted Stock. 

 (a) Restricted Stock Award Agreement. Each Award of Restricted
Stock will be evidenced by an Award Agreement that will specify the Period of Restriction (if any), the number of Shares granted, and such other terms and conditions as the Administrator determines. Unless the Administrator determines otherwise,
Shares of Restricted Stock will be held in escrow until the end of the Period of Restriction applicable to such Shares. All grants of Restricted Stock and interpretative decisions about Restricted Stock may only be made by the Administrator. 

(b) Restrictions: 
 (i)
Except as provided in this Section 5 or the Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated until the end of the Period of Restriction applicable to such Shares. 

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

  
 - 6 - 

 (iii) During the Period of Restriction, Service Providers holding Shares of Restricted Stock
will not be entitled to receive dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If the Administrator provides that dividends and distributions will be received and any such dividends
or distributions are paid in cash they will be subject to the same provisions regarding forfeitability as the Shares of Restricted Stock with respect to which they were paid and if such dividend 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 and, unless the Administrator determines otherwise, the Company will hold such Shares until the
restrictions on the Shares of Restricted Stock with respect to which they were paid have lapsed. 
 (iv) Except as otherwise provided in
this Section 5 or an Award Agreement, Shares of Restricted Stock covered by each Restricted Stock Award made under the Plan will be released from escrow when practicable after the last day of the applicable Period of Restriction. 

(v) The Administrator may impose, prior to grant, or remove any restrictions on Shares of Restricted Stock. 

 

	6.	Restricted Stock Units. 

 (a) Restricted Stock Unit Award Agreement. Each Award of
Restricted Stock Units will be evidenced by an Award Agreement that will specify the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units. 

(b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria that, depending on the extent to which the criteria
are met, will determine the number of Restricted Stock Units paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, divisional, business unit, or individual goals (that may include
continued employment or service) or any other basis determined by the Administrator in its sole discretion. 
 (c) Earning Restricted
Stock Units. Upon meeting the applicable vesting criteria, the Participant will have earned the Restricted Stock Units and will be paid as determined in Section 6(d). The Administrator may reduce or waive any criteria that must be met to
earn the Restricted Stock Units. 
 (d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made when
practicable after the date set forth in the Award Agreement and determined by the Administrator. The Administrator may settle earned Restricted Stock Units in cash, Shares, or a combination of both. 

 

	7.	Stock Appreciation Rights. 

 (a) Stock Appreciation Right Award Agreement. Each
Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the Exercise Price (which may not be less than 100% of Fair Market Value on the Grant Date), its Expiration Date, the conditions of exercise, and such other
terms and conditions as the Administrator determines. 
 (b) Payment of Stock Appreciation Right Amount. When a Participant exercises
a Stock Appreciation Right, he or she will be entitled to receive a payment from the Company equal to: 
 (i) the difference between the
Fair Market Value on the date of exercise and the Exercise Price multiplied by 
 (ii) the number of Shares with respect to which the Stock
Appreciation Right is exercised. 
 Payment upon Stock Appreciation Right exercise may be made in cash, in Shares of equivalent value, or any combination of
cash and Shares, with the determination of form of payment made by the Administrator. Shares issued upon exercise of a Stock Appreciation Right will be issued in the name of the Participant. Until Shares are issued (as evidenced by the entry on the
books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to a Stock Appreciation Right, despite the exercise
of the Stock Appreciation Right. The Company will issue (or cause to be issued) such Shares promptly after the Stock Appreciation Right is exercised. A Stock Appreciation Right may not be exercised for a fraction of a Share.

  
 - 7 - 

 
Exercising a Stock Appreciation Right in any manner will decrease (x) the number of Shares thereafter available under the Stock Appreciation Right by the number of Shares as to which the
Stock Appreciation Right is exercised and (y) the number of Shares thereafter available under the Plan by the number of Shares issued upon such exercise. 

(c) Expiration of Stock Appreciation Rights. A Stock Appreciation Right’s Expiration Date will be set forth in the Award
Agreement. A Stock Appreciation Right may expire before its expiration date under Sections 14 or 16(b) or under the Award Agreement 
 (d)
Tolling of Expiration. If exercising an Stock Appreciation Right prior to its expiration is not permitted because of Applicable Laws, other than the rules of any stock exchange or quotation system on which the Common Stock is listed or
quoted, the Stock Appreciation Right will remain exercisable until 30 days after the first date on which exercise would no longer be prevented by such provisions. If this would result in the Stock Appreciation Right remaining exercisable past its
Expiration Date, then it will remain exercisable only until the end of the later of (x) the first day on which its exercise would not be prevented by Section 19(a) and (y) its Expiration Date. 

 

	8.	Performance Stock Units and Performance Shares. 

 (a) Award Agreement. Each Award
of Performance Stock Units/Shares will be evidenced by an Award Agreement that will specify the time period during which the performance objectives or other vesting provisions will be measured (“Performance Period”) and the material terms
of the Award. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or individual goals (including, but not limited to, continued employment or service) or any other basis determined
by the Administrator. 
 (b) Value of Performance Stock Units/Shares. Each Performance Stock Unit will have an initial value
established by the Administrator on or before the Grant Date. Each Performance Share will have an initial value equal to the Fair Market Value on the Grant Date. 

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (that may
include continued employment or service). These objectives or vesting provisions may determine the number or value of Performance Stock Units/Shares paid out. 

(d) Earning of Performance Stock Units/Shares. After an applicable Performance Period has ended, the holder of Performance Stock
Units/Shares will be entitled to receive a payout of the number of Performance Stock Units/Shares earned by the Participant over the Performance Period. The Administrator may reduce or waive any performance objectives or other vesting provisions for
such Performance Stock Unit/Share. 
 (e) Payment of Performance Stock Units/Shares. Payment of earned Performance Stock Units/Shares
will be made when practicable after the end of the applicable Performance Period. Payment with respect to earned Performance Stock Units/Shares may be made in cash, in Shares of equivalent value, or any combination of cash and Shares, with the
determination of form of payment made by the Administrator. 
  

	9.	Performance Awards. 

 (a) Award Agreement. Each Performance Award will be
evidenced by an Award Agreement that will specify the Performance Period and the material terms of the Award. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or individual goals
(including, but not limited to, continued employment or service) or any other basis determined by the Administrator. 
 (b) Value of
Performance Awards. Each Performance Award’s threshold, target, and maximum payout values will be established by the Administrator on or before the Grant Date. 

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (that may
include continued employment or service). These objectives or vesting provisions will determine the value of the payout for the Performance Awards. 

(d) Earning of Performance Awards. After an applicable Performance Period has ended, the holder of a Performance Award will be entitled
to receive a payout for the Performance Award earned by the Participant over the Performance Period. The Administrator may reduce or waive any performance objectives or other vesting provisions for such Performance Award. 

  
 - 8 - 

 (e) Payment of Performance Awards. Payment of earned Performance Awards will be made when
practicable after the end of the applicable Performance Period. Payment with respect to earned Performance Awards will be made in cash, in Shares of equivalent value, or any combination of cash and Shares, with the determination of form of payment
made by the Administrator at the time of payment. 
  

	10.	Outside Director Limitations. 

 No Outside Director may be granted, in any Fiscal Year, Awards with a
grant date fair value (determined under U.S. generally accepted accounting principles) of more than $1,000,000, increased to $2,000,000 in connection with his or her initial service as an Outside Director. Awards granted to an individual while
he or she was an Employee, or while he or she was a Consultant but not an Outside Director, will not count for purpose of this limitation. 
  

	11.	Leaves of Absence/Transfer Between Locations/Change of Status. 

 (a) General.
Unless otherwise provided by the Administrator, a Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or other member of the Company Group employing such Employee or (ii) any
transfer between locations of the Company or members of the Company Group. 
 (b) Vesting. Unless a leave policy approved by the
Administrator provides otherwise or it is otherwise required by Applicable Law, vesting of Awards granted under the Plan will continue only for Participants on an approved leave of absence. 

(c) Incentive Stock Option Status. If a Participant’s leave of absence approved by the Company or other member of the Company
Group employing such Employee exceeds 3 months and reemployment upon expiration of such leave is not guaranteed by statute or contract, then 3 months following the 1st day of such leave the Participant will no longer be an employee for incentive
stock option purposes. If reemployment upon expiration of such leave of absence is not guaranteed by statute or contract, then 6 months following the 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. 
 (d) Protected Leaves. 

(i) Any leave of absence by a Participant will be subject to any Applicable Laws that apply to leaves of absence. 

(ii) For a Participant on a military leave, if required by Applicable Laws, vesting will continue for the longest period that vesting
continues under any other statutory or Company-approved leave of absence. When a Participant returns from military leave (under conditions that would entitle him or her to such protection under the Uniformed Services Employment and Reemployment
Rights Act), the Participant will be given vesting credit to the same extent as if the Participant had continued to provide services to the Company or other member of the Company Group, as applicable, through the military leave. 

(e) Changes in Status. If a Participant who is an Employee has a reduction in hours worked, the Administrator may unilaterally: 

(i) make a corresponding reduction in the number of Shares or cash amount subject to any portion of an Award that is scheduled to vest or
become payable after the date of such extend leave or reduction in hours; and 
 (ii) in lieu of or in combination with such a reduction,
extend the vesting or payment schedule applicable to such Award. 
 If any such reduction occurs, the Participant will have no right to any portion of the
Award that is reduced. 

  
 - 9 - 

 (f) Determinations. The effect of a Company-approved leave of absence, a transfer, or a
Participant’s reduction in hours of employment or service on the vesting of an Award shall be determined, under policies reviewed by the Administrator, by the Company’s senior human resources officer or other person performing that
function or, with respect to Directors or Officers by the Compensation Committee of the Board, and any such determination will be final. 
  

	12.	Transferability of Awards. 

 (a) General Rule. Unless determined otherwise by the
Administrator, or otherwise required by Applicable Laws, 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, the Award will be limited by any additional terms and conditions imposed by the Administrator. Any unauthorized transfer of an Award will be
void. 
 (b) Domestic Relations Orders. If approved by the Administrator, an Award may be transferred under a domestic relations
order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulations Section 1.421-1(b)(2). An Incentive Stock Option may be converted into a Nonstatutory Stock Option as a result of such
transfer. 
 (c) Limited Transfers for the Benefit of Family Members. The Administrator may permit an Award or Share issued under
this Plan to be assigned or transferred subject to the applicable limitations, set forth in the General Instructions to Form S-8 Registration Statement under the Securities Act, if applicable, and any other Applicable Laws. 

(d) Permitted Transferees. Any individual or entity to whom an Award is transferred will be subject to all of the terms and conditions
applicable to the Participant who transferred the Award, including the terms and conditions in this Plan and the Award Agreement. If an Award is unvested then the service of the Participant will continue to determine whether the Award will vest and
any Expiration Date. 
  

	13.	Adjustments; Dissolution or Liquidation. 

 (a) Adjustments. If any extraordinary
dividend or other extraordinary distribution (whether in 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, issuance of warrants or other rights to acquire securities of the Company, other change in the corporate structure of the Company affecting the Shares, or any similar equity restructuring
transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any of its successors) affecting the Shares occurs (including, without limitation, a Change in Control), the
Administrator, to prevent diminution or enlargement of the benefits or potential benefits intended to be provided 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 limits in Section 2 in such a manner as it deems equitable. Notwithstanding the foregoing, the conversion of any convertible securities of the Company and ordinary course
repurchases of shares or other securities of the Company will not be treated as an event that will require adjustment. 
 (b) Dissolution
or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant when 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. 
  

	14.	Change in Control. 

 (a) Administrator Discretion. If a Change in Control or a
merger of the Company with or into another corporation or other entity occurs, each outstanding Award will be treated as the Administrator determines, including, without limitation, that such Award be continued by the successor corporation or a
Parent or Subsidiary of the successor corporation. 
 (b) Identical Treatment Not Required. The Administrator need not take the same
action or actions with respect to all Awards or portions thereof or with respect to all Participants. The Administrator may take different actions with respect to the vested and unvested portions of an Award. The Administrator will not be required
to treat all Awards similarly in the transaction. 

  
 - 10 - 

 (c) Continuation. An Award will be considered continued if, following the Change in
Control or merger: 
 (i) the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the
transaction, the consideration (whether stock, cash, or other securities or property) received in the transaction by holders of Shares for each Share held on the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration received by the holders of a majority of the outstanding Shares); provided that if the consideration received in the transaction 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 exercising an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Stock Unit, Performance
Share or Performance Award, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the transaction;
or 
 (ii) the Award is terminated in exchange for an amount of cash and/or property, if any, equal to the amount that would have been
attained upon the exercise of such Award or realization of the Participant’s rights as of the date of the occurrence of the transaction. Any such cash or property may be subjected to any escrow applicable to holders of Common Stock in the
Change of Control. If as of the date of the occurrence of the transaction the Administrator determines that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be
terminated by the Company without payment. The amount of cash or property can be subjected to vesting and paid to the Participant over the original vesting schedule of the Award. 

(iii) Notwithstanding anything in this Section 14(c) to the contrary, an Award that vests, is earned or paid-out upon the
satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent; provided, however, a modification to such performance goals
only to reflect the successor corporation’s post-transaction corporate structure will not invalidate an otherwise valid Award assumption. 

(d) The Administrator will have authority to modify Awards in connection with a Change in Control or merger: 

(i) in a manner that causes them to lose their tax-preferred status, 

(ii) to terminate any right a Participant has to exercise an Option prior to vesting in the Shares subject to the Option (i.e., “early
exercise”), so that following the closing of the transaction the Option may only be exercised to the extent it is vested; 
 (iii) to
reduce the Exercise Price subject to the Award in a manner that is disproportionate to the increase in the number of Shares subject to the Award, as long as the amount that would be received upon exercise of the Award immediately before and
immediately following the closing of the transaction is equivalent and the adjustment complies with Treasury Regulation Section 1.409A-1(b)(v)(D); and 

(iv) to suspend a Participant’s right to exercise an Option during a limited period of time preceding and or following the closing of
the transaction without Participant consent if such suspension is administratively necessary or advisable to permit the closing of the transaction. 

(e) Non-Continuation. If the successor corporation does not continue for an Award (or some portion such Award), the Participant will
fully vest in (and have the right to exercise) 100% of the then-unvested Shares subject to his or her outstanding Options and Stock Appreciation Rights, all restrictions on 100% of the Participant’s outstanding Restricted Stock and Restricted
Stock Units will lapse, and, regarding 100% of Participant’s outstanding Awards with performance-based vesting, all performance goals or other vesting criteria will be treated as achieved at 100% of target levels and all other terms and
conditions met. In no event will vesting of an Award accelerate as to more than 100% of the Award. If Options or Stock Appreciation Rights are not continued when a Change in Control or a merger of the Company with or into another corporation or
other entity occurs, the Administrator will notify the Participant in writing or electronically that the Participant’s vested Options or Stock Appreciation Rights (after considering the foregoing vesting acceleration, if any) will be
exercisable for a period of time determined by the Administrator in its sole discretion and all of the Participant’s Options or Stock Appreciation Rights will terminate upon the expiration of such period (whether vested or unvested). 

  
 - 11 - 

 (f) Outside Director Awards. With respect to Awards granted to an Outside Director that
are continued, if on the date of or following such continuation 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 that is
not at the request of the acquirer, then the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares not otherwise vested or
exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be treated as achieved at 100% of target levels
and all other terms and conditions met. 
  

	15.	Tax Matters. 

 (a) Withholding Requirements. Prior to the delivery of any Shares
or cash under an Award (or exercise thereof) or such earlier time as any tax withholding obligations are due, the Company may deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy any taxes
(including the Participant’s social tax obligations) required to be withheld with respect to such Award (or exercise thereof). 

(b) Withholding Arrangements. The Administrator, in its sole discretion and under such procedures as it may specify from time to time,
may permit or may require a Participant to satisfy such tax withholding obligations, in whole or in part by (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash (including cash
from the sale of Shares issued to Participant) or Shares having a fair market value equal to the minimum statutory amount required to be withheld or a greater amount if that would not result in unfavorable financial accounting treatment,
(iii) delivering to the Company already-owned Shares having a fair market value equal to the minimum statutory amount required to be withheld, or (iv) requiring the Participant to engage in a cashless exercise transaction (whether through
a broker or otherwise) implemented by the Company in connection with the Plan. The fair market value of the Shares to be withheld or delivered will be determined as of the date the taxes must be withheld. 

(c) Compliance With Code Section 409A. Except as otherwise determined by the Administrator, it is intended that Awards will be
designed and operated so that they are either exempt from the application of Code Section 409A or comply with any requirements necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B) so that the grant, payment,
settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A and the Plan and each Award Agreement will be interpreted consistent with this intent. This Section 15(c) is not a guarantee to
any Participant of the consequences of his or her Awards. 
  

	16.	Other Terms. 

 (a) No Effect on Employment or Service. Neither the Plan nor any
Award will confer upon a Participant any right regarding continuing the Participant’s relationship as a Service Provider with the Company or member of the Company Group, nor will they interfere with the Participant’s right, or the
Participant’s employer’s right, to terminate such relationship with or without cause, to the extent permitted by Applicable Laws. 

(b) Forfeiture Events. 

(i) All Awards granted under the Plan will be subject to recoupment under any clawback policy that the Company is required to adopt pursuant
to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Laws. In
addition, the Administrator may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Administrator determines necessary or appropriate, including but not limited to a reacquisition right regarding previously
acquired Shares or other cash or property. Unless this Section 16(b) is specifically mentioned and waived in an Award Agreement or other document, no recovery of compensation under a clawback policy or otherwise will give a Participant the
right to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company. 

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

  
 - 12 - 

 (iii) If the Company is required to prepare an accounting restatement due to the material
noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under securities laws, any Participant who (i) knowingly or through gross negligence engaged in the misconduct or who knowingly or through gross
negligence failed to prevent the misconduct or (ii) is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, must reimburse the Company the amount of any payment in settlement of an
Award earned or accrued during the 12-month period following the first public issuance or filing with the United States Securities and Exchange Commission (whichever first occurred) of the financial document embodying such financial reporting
requirement. 
  

	17.	Term of Plan. 

 Subject to Section 20, the Plan will become effective upon the business day
immediately prior to the Registration Date. It will continue in effect until terminated under Section 18, but no Incentive Stock Options may be granted after 10 years from the date the Plan is adopted by the Board and Section 2(b) will
operate only until the 10th anniversary of the date the Plan is adopted by the Board. 
  

	18.	Amendment and Termination of the Plan. 

 (a) Amendment and Termination. The
Board or Compensation Committee of the Board may amend, alter, suspend or terminate the Plan. 
 (b) Stockholder Approval. The
Company will obtain stockholder approval of any Plan amendment to the extent necessary or desirable to comply with Applicable Laws. 
 (c)
Consent of Participants Generally Required. Subject to Section 18(d) below, no amendment, alteration, suspension or termination of the Plan or an Award under it will materially impair the rights of any Participant without a signed,
written agreement between the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it regarding Awards granted under the Plan prior to such termination. 

(d) Exceptions to Consent Requirement. 

(i) A Participant’s rights will not be deemed to have been impaired by any amendment, alteration, suspension or termination if the
Administrator, in its sole discretion, determines that the amendment, alteration, suspension or termination taken as a whole, does not materially impair the Participant’s rights; and 

(ii) Subject to any limitations of Applicable Laws, the Administrator may amend the terms of any one or more Awards without the affected
Participant’s consent even if it does materially impair the Participant’s right if such amendment is done 
 (1) in a manner
permitted under the Plan, 
 (2) to maintain the qualified status of the Award as an Incentive Stock Option under Code Section 422,

 (3) to change the terms of an Incentive Stock Option, if such change results in impairment of the Award only because it impairs the
qualified status of the Award as an Incentive Stock Option under Code Section 422, 
 (4) to clarify the manner of exemption from Code
Section 409A or compliance with any requirements necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B), or 

(5) to comply with other Applicable Laws. 
  

	19.	Conditions Upon Issuance of Shares. 

 (a) Legal Compliance. Shares will not be
issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws. If required by the 

  
 - 13 - 

 
Administrator, issuance will be further subject to the approval of counsel for the Company with respect to such compliance. The inability of the Company to obtain authority from any regulatory
body having jurisdiction or to complete or comply with the requirements of any Applicable Laws will relieve the Company of any liability regarding the failure to issue or sell such Shares as to which such authority, registration, qualification or
rule compliance was not obtained and the Administrator reserves the authority, without the consent of a Participant, to terminate or cancel Awards with or without consideration in such a situation. 

(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 during any such exercise that the Shares are being purchased only for investment and with no present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

 (c) Failure to Accept Award. If a Participant has not accepted an Award or has not taken all administrative and other steps (e.g.
setting up an account with a broker designated by the Company) necessary for the Company to issue Shares upon the vesting, exercise, or settlement of the Award prior to the first date the Shares subject such Award are scheduled to vest, then the
Award will be cancelled on such date and the Shares subject to such Award immediately will revert to the Plan for no additional consideration unless otherwise provided by the Administrator. 

 

	20.	Stockholder Approval. 

 The Plan will be subject to approval by the stockholders of the
Company within 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.

national market system, including without limitation the New York Stock Exchange, the NASDAQ Global Select Market, the NASDAQ Global Market or the NASDAQ Capital Market of The NASDAQ Stock Market, the Fair Market Value will be the closing sales
price for a Share (or the closing bid, if no sales were reported) as quoted on such exchange or system on the day of determination, as reported by such source as the Administrator determines to be reliable; 

(ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, the Fair Market Value of
a Share will be the mean between the high bid and low asked prices for the Common Stock on the day of determination (or, if no bids and asks were reported on that date on the last Trading Day such bids and asks were reported), as reported by such
source as the Administrator determines to be reliable; 
 (iii) For any Awards granted on the Registration Date, the Fair Market Value will
be the initial price to the public set forth in the final prospectus included within the registration statement in Form S-1 filed with the Securities and Exchange Commission for the initial public offering of the Company’s Common Stock; or 

(iv) Absent an established market for the Common Stock, the Fair Market Value will be determined in good faith by the Administrator. 

Notwithstanding the foregoing, if the determination date for the Fair Market Value occurs on a weekend, holiday or other non-Trading Day, the Fair Market
Value will be the price as determined under subsections (i) or (ii) above on the immediately preceding Trading Day, unless otherwise determined by the Administrator. In addition, for purposes of determining the fair market value of shares
for any reason other than the determination of the Exercise Price of Options or Stock Appreciation Rights, fair market value will be determined by the Administrator in a manner compliant with Applicable Laws and applied consistently for such
purpose. Note that the determination of fair market value for purposes of tax withholding may be made in the Administrator’s sole discretion subject to Applicable Laws and is not required to be consistent with the determination of Fair Market
Value for other purposes.

 EXHIBIT A 

TERMS AND CONDITIONS OF STOCK OPTION GRANT 

1. Grant. The Company grants the Participant an Option to purchase Shares of Common Stock as described in the Notice of Grant. If there
is a conflict between the Plan, this Agreement, or any other agreement with the Participant governing this Option, those documents will take precedence and prevail in the following order: (a) the Plan, (b) the Agreement, and (c) any
other agreement between the Company and the Participant governing this Option. 
 If the Notice of Grant designates this Option as an
Incentive Stock Option (“ISO”), this Option is intended to qualify as an ISO under Code Section 422. Even if this Option is designated an ISO, to the extent it first become exercisable as to more than $100,000 in any calendar
year, the portion in excess of $100,000 is not an ISO under Code Section 422(d) and that portion will be a Nonstatutory Stock Option (“NSO”). In addition, if the Participant exercises the Option after 3 months have passed
since he or she ceased to be an employee of the Company or a Parent or Subsidiary of the Company, it will no longer be an ISO. If there is any other reason this Option (or a portion of it) will not qualify as an ISO, to the extent of such
nonqualification, the Option will be an NSO. The Participant understands that he or she will have no recourse against the Administrator, any member of the Company Group, or any officer or director of a member of the Company Group if any portion of
this Option is not an ISO. 
 2. Vesting. This Option will only be exercisable (also referred to as vested) under the
Vesting Schedule in the Notice of Grant, Section 3 of this Agreement, or Section 14 of the Plan. Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest unless the Participant continues to be
a Service Provider until the time such vesting is scheduled to occur. The Administrator may modify the Vesting Schedule according to its authority under the Plan if the Participant takes a leave of absence or has a reduction in hours worked. 

3. Administrator Discretion. The Administrator may accelerate the vesting of any portion of this Option. In that case, this Option will
be vested as of the date and to the extent specified by the Administrator. 
 4. Forfeiture upon Termination of Status as a Service
Provider. Upon the Participant’s termination as a Service Provider for any reason, this Option will immediately stop vesting, and on the 30th day following the Termination of Status Date
(or any earlier date on or following the Termination of Status Date determined by the Administrator), any portion of this Option that has not yet vested will be immediately forfeited for no consideration, subject to Applicable Laws. The date of the
Participant’s termination as a Service Provider is detailed in Section 3(c) of the Plan. 
 5. Death of Participant. Any
distribution or delivery to be made to the Participant under this Agreement will, if he or she is then deceased, be made to the administrator or executor of his or her estate or, if the Administrator permits, his or her designated beneficiary. Any
such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations that
apply to the transfer. 
 6. Exercise of Option. 

(a) Right to Exercise. This Option may be exercised only before its Expiration Date and only under the Plan and this Agreement. 

  
 -3- 

 (b) Method of Exercise. To exercise this Option, the Participant must deliver and the
Administrator must receive an exercise notice according to procedures determined by the Administrator. The exercise notice must: 
 (i)
state the number of Shares as to which this Option is being exercised (“Exercised Shares”), 
 (ii) make any
representations or agreements required by the Company, 
 (iii) be accompanied by a payment of the total exercise price for all Exercised
Shares, and 
 (iv) be accompanied by a payment of all required Tax-Related Items (defined in Section 8(a) of this Agreement) for all
Exercised Shares. 
 The Option is exercised when both the exercise notice and payments due under Sections 6(b)(iii) and 6(b)(iv) have been received by the
Company for all Exercised Shares. The Administrator may designate a particular exercise notice to be used, but until a designation is made, the exercise notice attached to this Agreement as Exhibit C may be used. 

7. Method of Payment. The Participant may pay the exercise price for Exercised Shares by any of the following methods or a combination
of methods: 
 (a) cash; 
 (b)
check; 
 (c) wire transfer; 

(d) consideration received by the Company under a formal cashless exercise program adopted by the Company; or 

(e) surrender of other Shares, as long as the Company determines that accepting such Shares does not result in any adverse accounting
consequences to the Company. If Shares are surrendered, the value of those Shares will be the Fair Market Value for those Shares on the date they are surrendered. 

A non-U.S. resident’s methods of exercise may be restricted by the terms and condition of any appendix to this Agreement for the Participant’s
country (the “Appendix”). 
 8. Tax Obligations. 

(a) Tax Withholding.  

(i) No Shares will be issued to the Participant until he or she makes satisfactory arrangements (as determined by the Administrator) for the
payment of income, employment, social insurance, National Insurance Contributions, payroll tax, fringe benefit tax, payment on account, or other tax-related items related to his or her participation in the Plan and legally applicable to him or her
that the Administrator determines must be withheld (“Tax-Related Items”), including those that result from the grant, vesting, or exercise of this Option, the subsequent sale of Shares acquired under this Option or the receipt of
any dividends. If the Participant is a non-U.S. employee, the method of payment of Tax-Related Items may be restricted by any Appendix. If the Participant fails to make satisfactory arrangements for the payment of any Tax-Related Items under
this Agreement at the time of an attempted Option exercise, the Company may refuse to honor the exercise and refuse to deliver the Shares. 

  
 -4- 

 (ii) The Company has the right (but not the obligation) to satisfy any Tax-Related Items by
withholding from proceeds of a sale of Shares acquired upon the exercise of this Option arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent), and this will be the method by which such tax
withholding obligations are satisfied until the Company determines otherwise, subject to Applicable Laws. 
 (iii) The Company has the
right (but not the obligation) to satisfy any Tax-Related Items by reducing the number of Shares otherwise deliverable to the Participant. 

(iv) The Participant authorizes the Company and/or any member(s) of the Company Group for whom he or she is performing services (each, an
“Employer”) to withhold any Tax-Related Items legally payable by the Participant from his or her wages or other cash compensation paid to the Participant by the Company and/or the Employer(s) or from proceeds of the sale of Shares.

 (v) Further, if the Participant is subject to taxation in more than one jurisdiction between the Grant Date and the date of any relevant
taxable or tax withholding event, the Company and/or the Employer(s) or former Employer(s) may withhold or account for tax in greater than one jurisdiction. 

(vi) Regardless of any action of the Company or the Employer(s), the Participant acknowledges that the ultimate liability for all Tax-Related
Items is and remains his or her responsibility and may exceed the amount actually withheld by the Company or the Employer(s). The Participant further acknowledges that the Company and the Employer(s) (1) make no representations or undertakings
regarding the treatment of any Tax-Related Items in connection with any aspect of the Option; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of this Option to reduce or eliminate his or
her liability for Tax-Related Items or achieve any particular tax result. 
 (b) Tax Reporting. This Section 8(b) applies if the
Participant is a U.S. taxpayer. If this Option is partially or wholly an ISO, and if the Participant sells or otherwise disposes of any the Shares acquired by exercising the ISO portion on or before the later of (i) the date 2 years after the
Grant Date, or (ii) the date 1 year after the date of exercise, he or she may be subject to withholding of Tax-Related Items by the Company on the compensation income recognized by him or her and must immediately notify the Company in
writing of the disposition. 
 9. Forfeiture or Clawback. This Option (including any proceeds, gains or other economic benefit
received by the Participant from any subsequent sale of Shares resulting from the exercise) will be subject to any compensation recovery or clawback policy implemented by the Company before or after the date of this Agreement. This includes any
clawback policy adopted to comply with the requirements of Applicable Laws. 
 10. Rights as Stockholder. The Participant’s
rights as a stockholder of the Company (including the right to vote and to receive dividends and distributions) will not begin until Shares have been issued and recorded on the records of the Company or its transfer agents or registrars. 

11. Acknowledgements and Agreements. The Participant’s signature on the Notice of Grant accepting this Option indicates that: 

(a) HE OR SHE ACKNOWLEDGES AND AGREES THAT THE VESTING OF THIS OPTION IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AND THAT BEING HIRED,
GRANTED THIS OPTION, AND EXERCISING THE OPTION WILL NOT RESULT IN VESTING. 

  
 -5- 

 (b) HE OR SHE FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION AND AGREEMENT DO NOT CREATE AN
EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND DOES NOT INTERFERE IN ANY WAY WITH HIS OR HER RIGHT OR THE RIGHT OF THE EMPLOYER(S) TO TERMINATE HIS OR HER RELATIONSHIP
AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE, SUBJECT TO APPLICABLE LAWS. 
 (c) The Participant agrees that this Agreement and
its incorporated documents reflect all agreements on its subject matters and that he or she is not accepting this Agreement based on any promises, representations, or inducements other than those reflected in the Agreement. 

(d) The Participant understands that exercise of this Option is governed strictly by Sections 6, 7, and 8 of this Agreement and that
failure to comply with those Sections could result in the expiration of this Option, even if an attempt was made to exercise. 
 (e) The
Participant agrees that the Company’s delivery of any documents related to the Plan or this Option (including the Plan, the Agreement, the Plan’s prospectus and any reports of the Company provided generally to the Company’s
stockholders) to him or her may be made by electronic delivery, which may include the delivery of a link to a Company intranet or the Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail, or any
other means of electronic delivery specified by the Company. If the attempted electronic delivery of such documents fails, the Participant will be provided with a paper copy of the documents. The Participant acknowledges that he or she may receive
from the Company a paper copy of any documents that were delivered electronically at no cost to him or her by contacting the Company by telephone or in writing. The Participant may revoke his or her consent to the electronic delivery of documents or
may change the electronic mail address to which such documents are to be delivered (if the Participant has provided an electronic mail address) at any time by notifying the Company of such revoked consent or revised
e-mail address by telephone, postal service or electronic mail. Finally, the Participant understands that he or she is not required to consent to electronic delivery of documents. 

(f) The Participant may deliver any documents related to the Plan or this Option to the Company by e-mail or any other means of electronic
delivery approved by the Administrator, but he or she must provide the Company or any designated third party administrator with a paper copy of any documents if his or her attempted electronic delivery of such documents fails. 

(g) The Participant accepts that all good faith decisions or interpretations of the Administrator regarding the Plan and Awards under the Plan
are binding, conclusive, and final. No member of the Administrator will be personally liable for any such decisions or interpretations. 

(h) The Participant agrees that the Plan is established voluntarily by the Company, is discretionary in nature, and may be amended, suspended,
or terminated by the Company at any time, to the extent permitted by the Plan. 
 (i) The Participant agrees that the grant of this Option
is voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past. 

(j) The Participant agrees that any decisions regarding future Awards will be in the Company’s sole discretion. 

(k) The Participant agrees that he or she is voluntarily participating in the Plan. 

  
 -6- 

 (l) The Participant agrees that this Option and any Shares acquired under the Plan are not
intended to replace any pension rights or compensation. 
 (m) The Participant agrees that this Option, any Shares acquired under the Plan,
and their income and value of same are not part of normal or expected compensation for any purpose, including for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, holiday pay,
long-service awards, pension or retirement or welfare benefits, or similar payments. 
 (n) The Participant agrees that the future value of
the Shares underlying this Option is unknown, indeterminable, and cannot be predicted with certainty. 
 (o) The Participant understands
that if the underlying Shares do not increase in value, this Option will have no intrinsic monetary value. 
 (p) The Participant
understands that if this Option is exercised, the value of each Share received on exercise may increase or decrease in value, even below the Exercise Price per Share. 

(q) The Participant agrees that, for purposes of this Option, his or her engagement as a Service Provider is terminated as of the Termination
of Status Date (regardless of the reason for such termination and whether or not the termination is later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider or the terms of his or her
service agreement, if any), unless otherwise expressly provided in this Agreement or determined by the Administrator. 
 (r) The Participant
agrees that any right to vest in this Option terminates as of the Termination of Status Date and will not be extended by any notice period (e.g., the period that he or she is a Service Provider would not include any contractual notice period or any
period of “garden leave” or similar period mandated under employment laws (including common law, if applicable) in the jurisdiction where he or she is a Service Provider or by his or her service agreement or employment agreement, if any,
unless he or she is providing bona fide services during such time). 
 (s) The Participant agrees that the period during which the
Participant may exercise the vested portion of this Option after a termination of his or her status as a Service Provider (if any) will start as of the Termination of Status Date (regardless of the reason for such termination and whether or not
the termination is later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider or the terms of his or her service agreement, if any), unless otherwise expressly provided in this Agreement or
determined by the Administrator. 
 (t) The Participant agrees that the Administrator has the exclusive discretion to determine when he or
she is no longer actively providing services for purposes of this Option (including whether he or she is still considered to be providing services while on a leave of absence). 

(u) The Participant agrees that no member of the Company Group is liable for any foreign exchange rate fluctuation between the
Participant’s local currency and the United States Dollar that may affect the value of this Option or of any amounts due to him or her from the exercise of this Option or the subsequent sale of any Shares acquired upon exercise. 

(v) The Participant has read and agrees to the Data Privacy Provisions of Section 12 of this Agreement. 

(w) The Participant agrees that he or she has no claim or entitlement to compensation or damages from any forfeiture of this Option resulting
from the termination of his or her status as a Service 

  
 -7- 

 
Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider or the terms of his or her
service agreement, if any), and in consideration of the grant of this Option to which he or she is otherwise not entitled, he or she irrevocably agrees never to institute any claim against the Company or any member of the Company Group, waives
his or her ability (if any) to bring any such claim, and releases the Company and all members of the Company Group from any such claim. If any such claim is nevertheless allowed by a court of competent jurisdiction, then the Participant’s
participation in the Plan constitutes his or her irrevocable agreement to not pursue such claim and to execute any and all documents necessary to request dismissal or withdrawal of such claim. 

12. Data Privacy.  

(a) The Participant voluntarily consents to the collection, use and transfer, in electronic or other form, of his or her personal data as
described in this Agreement and any other Award materials (“Data”) by and among, as applicable, the Employer(s), the Company and any member of the Company Group for the exclusive purpose of implementing, administering, and
managing his or her participation in the Plan. 
 (b) The Participant understands that the Company and the Employer(s) may hold
certain personal information about him or her, including, but not limited to, his or her name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of
stock or directorships held in the Company, details of all equity awards or any other entitlement to stock awarded, canceled, exercised, vested, unvested or outstanding in his or her favor, for the exclusive purpose of implementing, administering,
and managing the Plan. 
 (c) The Participant understands that Data will be transferred to one or more a stock plan service
provider(s) selected by the Company, which may assist the Company with the implementation, administration, and management of the Plan. The Participant understands that the recipients of the Data may be located in the United States or elsewhere, and
that the recipient’s country (e.g., the United States) may have different data privacy laws and protections than his or her country. The Participant understands that if he or she resides outside the United States, he or she may request a list
with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Participant authorizes the Company and any other possible recipients that may assist the Company (presently or in
the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing his or her participation in the
Plan. 
 (d) The Participant understands that Data will be held only as long as is necessary to implement, administer and manage his
or her participation in the Plan. The Participant understands that if he or she resides in certain jurisdictions outside the United States, to the extent required by Applicable Laws, he or she may, at any time, request access to Data, request
additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents given by accepting this Option, in any case without cost, by contacting in writing his or her local human
resources representative. Further, the Participant understands that he or she is providing these consents on a purely voluntary basis. If the Participant does not consent or if he or she later seeks to revoke his or her consent, his or her
engagement as a Service Provider with the Employer(s) will not be adversely affected; the only consequence of refusing or withdrawing his or her consent is that the Company will not be able to grant him or her awards under the Plan or administer or
maintain awards. Therefore, the Participant understands that refusing or withdrawing his or her consent may affect his or her ability to participate in the Plan (including the right to retain this Option). The Participant understands that he or she
may contact his or her local human resources representative for more information on the consequences of his or her refusal to consent or withdrawal of consent.

Square, Inc., 1455 Market Street, Suite 600, San Francisco, CA 94103 until the Company designates another address in writing. 
 (b)
Non-Transferability of Option. This Option may not be transferred other than by will or the laws of descent or distribution and may be exercised during the lifetime of the Participant only by him or her or his or her representative following
a Disability. 
 (c) Binding Agreement. If this Option is transferred, this Agreement will be binding upon and inure to the benefit
of the heirs, legatees, legal representatives, successors, and assigns of the parties to this Agreement. 
 (d) Additional Conditions to
Issuance of Stock. If the Company determines that the listing, registration, qualification, or rule compliance of the Common Stock on any securities exchange or under any state, federal, or foreign law or the tax code and related regulations or
the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to the Participant (or his or her estate), the Company will try to meet the requirements of any such state, federal,
or foreign law or securities exchange and to obtain any such consent or approval of any such governmental authority or securities exchange, but the Shares will not be issued until such conditions have been met in a manner acceptable to the Company.

 (e) Captions. Captions provided in this Agreement are for convenience only and are not to serve as a basis for interpretation or
construction of this Agreement. 
 (f) Agreement Severable. If any provision of this Agreement is held invalid or unenforceable, that
provision will be severed from the remaining provisions of this Agreement and the invalidity or unenforceability will have no effect on the remainder of the Agreement. 

(g) Non-U.S. Appendix. This Option is subject to any special terms and conditions set forth in any Appendix. If the Participant
relocates to a country included in the Appendix, the special terms and conditions for that country will apply to him or her to the extent the Company determines that applying such terms and conditions is necessary or advisable for legal or
administrative reasons. 
 (h) Choice of Law; Choice of Forum. The Plan, this Agreement, this Option, and all determinations made and
actions taken under the Plan, to the extent not otherwise governed by the laws of the United States, will be governed by the laws of the State of Delaware without giving effect to principles of conflicts of law. For purposes of litigating any
dispute that arises under the Plan, the Participant’s acceptance of this Option is his or her consent to the jurisdiction of the State of Delaware and his or her agreement that any such litigation will be conducted in the Delaware Court of
Chancery or the federal courts for the United States for the District of Delaware and no other courts, regardless of where he or she is performing services. 

(i) Modifications to the Agreement. The Plan and this Agreement constitute the entire understanding of the parties on the subjects
covered. The Participant expressly warrants that he or she is not accepting this Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Agreement or the Plan can be made only
in an express written contract executed by a duly authorized officer of the Company. The Company reserves the right to revise the Agreement as it deems necessary or advisable, in its sole discretion and without the consent of the Participant, to
comply with Code Section 409A, to otherwise avoid imposition of any additional tax or income recognition under Code Section 409A in connection with this Option, or to comply with other Applicable Laws. 

  
 -9- 

 (j) Waiver. The Participant acknowledges that a waiver by the Company of a breach of any
provision of this Agreement will not operate or be construed as a waiver of any other provision of this Agreement or of any subsequent breach of this Agreement by him or her.

APPENDIX TO STOCK OPTION AGREEMENT 

Terms and Conditions 
 This Appendix to Stock
Option Agreement (the “Appendix”) includes additional terms and conditions that govern this Option granted to the Participant under the Plan if he or she resides in one of the countries listed below on the Grant Date or he or she
moves to one of the listed countries. 
 Notifications 

This Appendix may also include information regarding exchange controls and certain other issues of which the Participant should be aware with respect to
participation in the Plan. The information is based on the securities, exchange control, and other Applicable Laws in effect in the respective countries as of
                    , 20    . Such Applicable Laws are often complex and change frequently. As a result, the Company strongly
recommends that the Participant not rely on the information in this Appendix as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Participant sells
Shares acquired under the Plan. 
 In addition, the information contained in this Appendix is general in nature and may not apply to the Participant’s
particular situation, and the Company is not in a position to assure him or her of a particular result. The Participant is advised to seek appropriate professional advice as to how the Applicable Laws in his or her country may apply to his or her
situation. 
 Finally, if the Participant is a citizen or resident of a country other than the one in which he or she is currently working, transfers
employment after this Option is granted, or is considered a resident of another country for local law purposes, the information in this Appendix may not apply to him or her, and the Administrator will determine to what extent the terms and
conditions in this Appendix apply.

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK AWARD 

1. Grant. The Company grants the Participant an award of Restricted Stock as described in the Notice of Grant. If there is a conflict
between the Plan, this Agreement, or any other agreement with the Participant governing these Shares of Restricted Stock, those documents will take precedence and prevail in the following order: (a) the Plan, (b) the Agreement, and
(c) any other agreement between the Company and the Participant governing these Shares of Restricted Stock. 
 2. Escrow of
Shares. 
 (a) Once the Participant signs this Agreement, all of these Shares of Restricted Stock will be delivered to an escrow holder
designated by the Company (the “Escrow Holder”) and will be held by the Escrow Holder until these Shares of Restricted Stock vest or the Participant ceases to be a Service Provider. 

(b) The Escrow Holder is not liable for any act it does or does not do for purposes of holding these Shares of Restricted Stock in escrow.

 (c) The Escrow Holder will transfer any vested Shares of Restricted Stock to the Participant at his or her request. 

(d) The Participant has no right to receive cash dividends on any of these Shares of Restricted Stock that are held in escrow but has all
other rights of a stockholder for such Shares, including the right to vote. 
 (e) These Shares of Restricted Stock will be subject to any
adjustments made according to Section 13(a) of the Plan. 
 (f) The Company may instruct the transfer agent for the Common Stock to

3. Vesting. These Shares of Restricted Stock will vest only under the Vesting Schedule in the Notice of Grant, Section 4 of this
Agreement, or Section 14 of the Plan. Shares of Restricted Stock scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest unless the Participant continues to be a Service Provider until the time such
vesting is scheduled to occur. The Administrator may modify the Vesting Schedule according to its authority under the Plan if the Participant takes a leave of absence or has a reduction in hours worked. 

4. Administrator Discretion. The Administrator has the discretion to accelerate the vesting of any number of unvested Shares of
Restricted Stock at any time, subject to the terms of the Plan. In that case, those Shares of Restricted Stock will be vested as of the date specified by the Administrator. 

5. Forfeiture upon Termination of Status as a Service Provider. Upon the Participant’s termination as a Service Provider for any
reason, these Shares of Restricted Stock will immediately stop vesting, and on the 30th day following the Termination of Status Date (or any earlier date on or following the Termination of Status
Date determined by the Administrator), any of these Shares of Restricted Stock that have not yet vested will be forfeited by the Participant and automatically transferred by the Escrow Holder to the Company at no cost to the Company, subject to
Applicable Laws. The Participant will not be refunded any price paid for such Shares and will have no further rights under this Agreement. The Participant appoints the Escrow Holder with

authority in the name and on behalf of the Participant) to take any action and execute all documents and instruments, including stock powers necessary to transfer the certificate(s) evidencing such unvested Shares of Restricted Stock to the Company

6. Death of Participant. Any distribution or delivery to be made to the Participant under this Agreement will, if he or she is then
deceased, be made to the administrator or executor of his or her estate or, if the Administrator permits, his or her designated beneficiary. Any such transferee must furnish the Company with (a) written notice of his or her status as
transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations that apply to the transfer.

No Shares of Restricted Stock may be released from escrow until the Participant makes satisfactory arrangements (as determined by the Administrator) for the payment of income, employment, social insurance, National Insurance Contributions, payroll
tax, fringe benefit tax, payment on account, or other tax-related items related to his or her participation in the Plan and legally applicable to him or her that the Administrator determines must be withheld
(“Tax-Related Items”), including those that result from the grant, vesting, or subsequent sale of Shares of Restricted Stock or the receipt of any dividends . If the Participant is a non-U.S.
employee, the method of payment of Tax-Related Items may be restricted by any Appendix. If the Participant fails to make satisfactory arrangements for the payment of any Tax-Related Items under this Agreement when any of these Shares of Restricted
Stock otherwise are supposed to vest or Tax-Related Items related to these Shares of Restricted Stock otherwise are due, he or she will permanently forfeit the applicable Shares of Restricted Stock and such Shares of Restricted Stock will be
returned to the Company at no cost to the Company. 
 (b) The Company has the right (but not the obligation) to satisfy any Tax-Related
Items by withholding from proceeds of a sale of any of these Shares of Restricted Stock that have vested arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent), and this will be the method
by which such tax withholding obligations are satisfied until the Company determines otherwise, subject to Applicable Laws. 
 (c) The
Company also has the right (but not the obligation) to satisfy any Tax-Related Items by reducing the number of Shares otherwise deliverable to the Participant. 

(d) Further, if the Participant is subject to taxation in more than one jurisdiction between the Grant Date and the date of any relevant
taxable or tax withholding event, the Company and/or any member of the Company Group for whom he or she is performing services (each, an “Employer”) or former Employer(s) may withhold or account for tax in more than one
jurisdiction. 
 (e) Regardless of any action of the Company or the Employer(s), the Participant acknowledges that the ultimate liability
for all Tax-Related Items is and remains his or her responsibility and may exceed the amount actually withheld by the Company or the Employer(s). The Participant further acknowledges that the Company and the Employer(s) (i) make no
representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of these Shares of Restricted Stock and (ii) do not commit to and are under no obligation to structure the terms of the grant or any
aspect of these Shares of Restricted Stock to reduce or eliminate his or her liability for Tax-Related Items or achieve any particular tax result.

 8. Forfeiture or Clawback. These Shares of Restricted Stock (including any proceeds, gains
or other economic benefit received by the Participant from their subsequent sale) will be subject to any compensation recovery or clawback policy implemented by the Company before or after the date of this Agreement. This includes any clawback
policy adopted to comply with the requirements of Applicable Laws. 
 9. Rights as Stockholder. The Participant’s rights as a
stockholder of the Company (including the right to vote and to receive dividends and distributions) will not begin until these Shares of Restricted Stock have been issued and recorded on the records of the Company or its transfer agents or
registrars. 
 10. Acknowledgements and Agreements. The Participant’s signature on the Notice of Grant accepting these Shares of
Restricted Stock indicates that: 
 (a) HE OR SHE ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE SHARES OF RESTRICTED STOCK IS EARNED ONLY
BY CONTINUING AS A SERVICE PROVIDER AND THAT BEING HIRED OR BEING GRANTED THESE SHARES OF RESTRICTED STOCK DO NOT RESULT IN VESTING. 
 (b)
HE OR SHE FURTHER ACKNOWLEDGES AND AGREES THAT THESE SHARES OF RESTRICTED STOCK AND THIS AGREEMENT DO NOT CREATE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL AND DOES

 (g) The Participant agrees that the Plan is established voluntarily by the Company, is
discretionary in nature, and may be amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan.

(i) The Participant agrees that any decisions regarding future Awards will be in the Company’s sole discretion. 

(j) The Participant agrees that he or she is voluntarily participating in the Plan.

certainty. 
 (n) The Participant agrees that, for purposes of these Shares of Restricted Stock , his or her engagement as a Service
Provider is terminated as of the Termination of Status Date (regardless of the reason for such termination and whether or not the termination is later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a
Service Provider or the terms of his or her service agreement, if any), unless otherwise expressly provided in this Agreement or determined by the Administrator. 

(o) The Participant agrees that any right to vest in these Shares of Restricted Stock terminates as of the Termination of Status Date and will
not be extended by any notice period (e.g., the period that he or she is a Service Provider would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws (including common
law, if applicable) in the jurisdiction where he or she is a Service Provider or by his or her service agreement or employment agreement, if any, unless he or she is providing bona fide services during such time). 

(p) The Participant agrees that the Administrator has the exclusive discretion to determine when he or she is no longer actively providing
services for purposes of these Shares of Restricted Stock (including whether he or she is still considered to be providing services while on a leave of absence). 

(q) The Participant agrees that no member of the Company Group is liable for any foreign exchange rate fluctuation between the
Participant’s local currency and the United States Dollar that may affect the value of these Shares of Restricted Stock or of any amounts due to him or her upon the sale of any of these Shares of Restricted Stock. 

(r) The Participant has read and agrees to the Data Privacy Provisions of Section 11 of this Agreement. 

  
 -6- 

 (s) The Participant agrees that he or she has no claim or entitlement to compensation or damages
from any forfeiture of these Shares of Restricted Stock resulting from the termination of his or her status as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the
jurisdiction where he or she is a Service Provider or the terms of his or her service agreement, if any), and in consideration of the grant of these Shares of Restricted Stock to which he or she is otherwise not entitled, he or she irrevocably
agrees never to institute any claim against the Company or any member of the Company Group, waives his or her ability (if any) to bring any such claim, and releases the Company and all members of the Company Group from any such claim. If any such
claim is nevertheless allowed by a court of competent jurisdiction, then the Participant’s participation in the Plan constitutes his or her irrevocable agreement to not pursue such claim and to execute any and all documents necessary to request
dismissal or withdrawal of such claim. 
 11. Data Privacy.  

(a) The Participant voluntarily consents to the collection, use and transfer, in electronic or other form, of his or her personal data as
described in this Agreement and any other Award materials (“Data”) by and among, as applicable, the Employer(s), the Company and any member of the Company Group for the exclusive purpose of implementing, administering, and
managing his or her participation in the Plan. 
 (b) The Participant understands that the Company and the Employer(s) may hold
certain personal information about him or her, including, but not limited to, his or her name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of
stock or directorships held in the Company, details of all equity awards or any other entitlement to stock awarded, canceled, exercised, vested, unvested or outstanding in his or her favor, for the exclusive purpose of implementing, administering,
and managing the Plan. 
 (c) The Participant understands that Data will be transferred to one or more a stock plan service
provider(s) selected by the Company, which may assist the Company with the implementation, administration, and management of the Plan. The Participant understands that the recipients of the Data may be located in the United States or elsewhere, and
that the recipient’s country (e.g., the United States) may have different data privacy laws and protections than his or her country. The Participant understands that if he or she resides outside the United States, he or she may request a list
with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Participant authorizes the Company and any other possible recipients that may assist the Company (presently or in
the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing his or her participation in the
Plan. 
 (d) The Participant understands that Data will be held only as long as is necessary to implement, administer and manage his
or her participation in the Plan. The Participant understands that if he or she resides in certain jurisdictions outside the United States, to the extent required by Applicable Laws, he or she may, at any time, request access to Data, request
additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents given by accepting these Shares of Restricted Stock, in any case without cost, by contacting in writing his
or her local human resources representative. Further, the Participant understands that he or she is providing these consents on a purely voluntary basis. If the Participant does not consent or if he or she later seeks to revoke his or her consent,
his or her engagement as a Service Provider with the Employer(s) will not be adversely affected; the only consequence of refusing or withdrawing his or her consent is that the Company will not be able to grant him or her awards under the Plan or
administer or maintain awards. Therefore, the Participant understands that refusing or withdrawing his or her consent may affect his or her ability to participate in the Plan (including the right to retain

  
 -7- 

 
these Shares of Restricted Stock). The Participant understands that he or she may contact his or her local human resources representative for more information on the consequences of his or her
refusal to consent or withdrawal of consent.

of the heirs, legatees, legal representatives, successors, and assigns of the parties to this Agreement.

related regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of these Shares of Restricted Stock or their release from escrow to the Participant (or his or her

Captions provided in this Agreement are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

without the consent of the Participant, to comply with other Applicable Laws.

APPENDIX TO RESTRICTED STOCK AGREEMENT 

Terms and Conditions 
 This Appendix to Restricted
Stock Agreement (the “Appendix”) includes additional terms and conditions that govern these Shares of Restricted Stock granted to the Participant under the Plan if he or she resides in one of the countries listed below on the Grant
Date or he or she moves to one of the listed countries. 
 Notifications 

This Appendix may also include information regarding exchange controls and certain other issues of which the Participant should be aware with respect to
participation in the Plan. The information is based on the securities, exchange control, and other Applicable Laws in effect in the respective countries as of
                    , 20    . Such Applicable Laws are often complex and change frequently. As a result, the Company strongly
recommends that the Participant not rely on the information in this Appendix as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Participant sells
Shares acquired under the Plan. 
 In addition, the information contained in this Appendix is general in nature and may not apply to the Participant’s
particular situation, and the Company is not in a position to assure him or her of a particular result. The Participant is advised to seek appropriate professional advice as to how the Applicable Laws in his or her country may apply to his or her
situation. 
 Finally, if the Participant is a citizen or resident of a country other than the one in which he or she is currently working, transfers
employment after these Shares of Restricted Stock are granted, or is considered a resident of another country for local law purposes, the information in this Appendix may not apply to him or her, and the Administrator will determine to what extent
the terms and conditions in this Appendix apply.

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT AWARD 

1. Grant. The Company grants the Participant an award of RSUs as described in the Notice of Grant. If there is a conflict between the
Plan, this Agreement, or any other agreement with the Participant governing these RSUs, those documents will take precedence and prevail in the following order: (a) the Plan, (b) the Agreement, and (c) any other agreement between the
Company and the Participant governing these RSUs. 
 2. Company’s Obligation to Pay. Each RSU is a right to receive a Share on
the date it vests. Until an RSU vests, the Participant has no right to payment of the Share. Before a vested RSU is paid, the RSU is an unsecured obligation of the Company, payable (if at all) only from the Company’s general assets. A vested
RSU will be paid to the Participant (or in the event of his or her death, to his or her estate) in whole Shares as soon as practicable after vesting (but no later than 60 days following the vesting date), subject to him or her satisfying any
obligations for Tax-Related Items (as defined in Section 7 of this Agreement) and any delay in payment required under Section 7 of this Agreement. The Participant cannot specify (directly or indirectly) the taxable year of the payment of
any vested RSU under this Agreement. 
 3. Vesting. These RSUs will vest only under the Vesting Schedule in the Notice of Grant,
Section 4 of this Agreement, or Section 14 of the Plan. RSUs scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest unless the Participant continues to be a Service Provider until the time such
vesting is scheduled to occur. The Administrator may modify the Vesting Schedule according to its authority under the Plan if the Participant takes a leave of absence or has a reduction in hours worked. 

4. Administrator Discretion. The Administrator has the discretion to accelerate the vesting of any RSUs at any time, subject to the
terms of the Plan. In that case, those RSUs will be vested as of the date specified by the Administrator. 
 5. Forfeiture upon
Termination of Status as a Service Provider. Upon the Participant’s termination as a Service Provider for any reason, these RSUs will immediately stop vesting, and on the 30th day
following the Termination of Status Date (or any earlier date on or following the Termination of Status Date determined by the Administrator), any of these RSUs that have not yet vested will be forfeited by the Participant, subject to Applicable
Laws. The date of the Participant’s termination as a Service Provider is detailed in Section 3(c) of the Plan. 
 6. Death of
Participant. Any distribution or delivery to be made to the Participant under this Agreement will, if he or she is then deceased, be made to the administrator or executor of his or her estate or, if the Administrator permits, his or her
designated beneficiary. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any
laws or regulations that apply to the transfer. 
 7. Tax Obligations. 

(a) Tax Withholding.  

(i) No Shares will be issued to the Participant until he or she makes satisfactory arrangements (as determined by the Administrator) for the
payment of income, employment, social insurance, National Insurance Contributions, payroll tax, fringe benefit tax, payment on account, or other tax-related items related to his or her participation in the Plan and legally applicable to him or her
that the Administrator 

  
 -1- 

 
determines must be withheld (“Tax-Related Items”), including those that result from the grant, vesting, or payment of these RSUs, the subsequent sale of Shares acquired pursuant
to such payment, or the receipt of any dividends. If the Participant is a non-U.S. employee, the method of payment of Tax-Related Items may be restricted by any Appendix. If the Participant fails to make satisfactory arrangements for the
payment of any Tax-Related Items under this Agreement when any of these RSUs otherwise are supposed to vest or Tax-Related Items related to RSUs otherwise are due, he or she will permanently forfeit the
applicable RSUs and any right to receive Shares under such RSUs, and such RSUs will be returned to the Company at no cost to the Company. 

(ii) The Company has the right (but not the obligation) to satisfy any Tax-Related Items by withholding from proceeds of a sale of Shares
acquired upon payment of these RSUs arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent), and this will be the method by which such tax withholding obligations are satisfied until the
Company determines otherwise, subject to Applicable Laws. 
 (iii) The Company also has the right (but not the obligation) to satisfy any
Tax-Related Items by reducing the number of Shares otherwise deliverable to the Participant. 
 (iv) Further, if the Participant is subject
to taxation in more than one jurisdiction between the Grant Date and the date of any relevant taxable or tax withholding event, the Company and/or any member of the Company Group for whom he or she is performing services (each, an
“Employer”) or former Employer(s) may withhold or account for tax in more than one jurisdiction. 
 (v) Regardless of any
action of the Company or the Employer(s), the Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains his or her responsibility and may exceed the amount actually withheld by the Company or the Employer(s). The
Participant further acknowledges that the Company and the Employer(s) (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of these RSUs and (2) do not commit to and are
under no obligation to structure the terms of the grant or any aspect of these RSUs to reduce or eliminate his or her liability for Tax-Related Items or achieve any particular tax result. 

(b) Code Section 409A. This Section 7(b) does not apply if the Participant is not a U.S. taxpayer. 

(i) If the vesting of any RSUs is accelerated in connection with a termination of the Participant’s status as a Service Provider that is
a “separation from service” within the meaning of Code Section 409A and (x) the Participant is a “specified employee” within the meaning of Code Section 409A at that time and (y) the payment of such
accelerated RSUs would result in the imposition of additional tax under Code Section 409A if paid to the Participant within the 6-month period following such termination, then the accelerated RSUs will not be paid until the first day after the
6-month period ends. 
 (ii) If the Participant’s status as a Service Provider terminates due to death or the Participant dies after
he or she stops being a Service Provider, the delay under Section 7(b)(i) of this Agreement will not apply, and these RSUs will be paid in Shares to the Participant’s estate as soon as practicable. 

(iii) All payments and benefits under this Agreement are intended to be exempt from Code Section 409A or comply with any requirements
necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B) so that none of these RSUs or Shares issuable upon the vesting of RSUs will be subject to the additional tax imposed under Code Section 409A, and any
ambiguities will be interpreted according to that intent. 

  
 -2- 

 (iv) Each payment under this Agreement is a separate payment under Treasury Regulations
Section 1.409A-2(b)(2). 
 8. Forfeiture or Clawback. These RSUs (including any proceeds, gains or other economic benefit
received by the Participant from any subsequent sale of Shares issued upon payment of the RSUs) will be subject to any compensation recovery or clawback policy implemented by the Company before or after the date of this Agreement. This includes any
clawback policy adopted to comply with the requirements of Applicable Laws. 
 9. Rights as Stockholder. The Participant’s
rights as a stockholder of the Company (including the right to vote and to receive dividends and distributions) will not begin until Shares have been issued and recorded on the records of the Company or its transfer agents or registrars. 

10. Acknowledgements and Agreements. The Participant’s signature on the Notice of Grant accepting these RSUs indicates that:

HER RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE, SUBJECT TO APPLICABLE LAWS. 
 (c) The Participant agrees that
this Agreement and its incorporated documents reflect all agreements on its subject matters and that he or she is not accepting this Agreement based on any promises, representations, or inducements other than those reflected in the Agreement. 

(d) The Participant agrees that the Company’s delivery of any documents related to the Plan or these RSUs (including the Plan, the
Agreement, the Plan’s prospectus, and any reports of the Company provided generally to the Company’s stockholders) to him or her may be made by electronic delivery, which may include the delivery of a link to a Company intranet or to the
Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail, or any other means of electronic delivery specified by the Company. If the attempted electronic delivery of such documents fails, the
Participant will be provided with a paper copy of the documents. The Participant acknowledges that he or she may receive from the Company a paper copy of any documents that were delivered electronically at no cost to him or her by contacting the
Company by telephone or in writing. The Participant may revoke his or her consent to the electronic delivery of documents or may change the electronic mail address to which such documents are to be delivered (if the Participant has provided an
electronic mail address) at any time by notifying the Company of such revoked consent or revised e-mail address by telephone, postal service or electronic mail. Finally, the Participant understands that he or
she is not required to consent to electronic delivery of documents. 
 (e) The Participant may deliver any documents related to the Plan or
these RSUs to the Company by e-mail or any other means of electronic delivery approved by the Administrator, but he or she must provide the Company or any designated third party administrator with a paper copy of any documents if his or her

(i) The Participant agrees that any decisions regarding future Awards will be in the Company’s sole discretion. 

(j) The Participant agrees that he or she is voluntarily participating in the Plan.

(o) The Participant agrees that any right to vest in these RSUs terminates as of the Termination of Status Date and will not be extended by

 (r) The Participant has read and agrees to the Data Privacy Provisions of Section 11 of this
Agreement. 
 (s) The Participant agrees that he or she has no claim or entitlement to compensation or damages from any forfeiture of these
RSUs resulting from the termination of his or her status as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider or the
terms of his or her service agreement, if any), and in consideration of the grant of these RSUs to which he or she is otherwise not entitled, he or she irrevocably agrees never to institute any claim against the Company or any member of the
Company Group, waives his or her ability (if any) to bring any such claim, and releases the Company and all members of the Company Group from any such claim. If any such claim is nevertheless allowed by a court of competent jurisdiction, then the
Participant’s participation in the Plan constitutes his or her irrevocable agreement to not pursue such claim and to execute any and all documents necessary to request dismissal or withdrawal of such claim. 

11. Data Privacy. 

(a) The Participant voluntarily consents to the collection, use and transfer, in electronic or other form, of his or her personal data as
described in this Agreement and any other Award materials (“Data”) by and among, as applicable, the Employer(s), the Company and any member of the Company Group for the exclusive purpose of implementing, administering, and
managing his or her participation in the Plan. 
 (b) The Participant understands that the Company and the Employer(s) may hold
certain personal information about him or her, including, but not limited to, his or her name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any shares of
stock or directorships held in the Company, details of all equity awards or any other entitlement to stock awarded, canceled, exercised, vested, unvested or outstanding in his or her favor, for the exclusive purpose of implementing, administering,
and managing the Plan. 
 (c) The Participant understands that Data will be transferred to one or more a stock plan service
provider(s) selected by the Company, which may assist the Company with the implementation, administration, and management of the Plan. The Participant understands that the recipients of the Data may be located in the United States or elsewhere, and
that the recipient’s country (e.g., the United States) may have different data privacy laws and protections than his or her country. The Participant understands that if he or she resides outside the United States, he or she may request a list
with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Participant authorizes the Company and any other possible recipients that may assist the Company (presently or in
the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing his or her participation in the
Plan. 
 (d) The Participant understands that Data will be held only as long as is necessary to implement, administer and manage his
or her participation in the Plan. The Participant understands that if he or she resides in certain jurisdictions outside the United States, to the extent required by Applicable Laws, he or she may, at any time, request access to Data, request
additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents given by accepting these RSUs, in any case without cost, by contacting in writing his or her local human
resources representative. Further, the Participant understands that he or she is providing these consents on a purely voluntary basis. If the Participant does not consent or if he or she later seeks to revoke his or her consent, his or her
engagement as a Service Provider with the Employer(s) will not be adversely affected; the only consequence of refusing or withdrawing his 

  
 -5- 

 
or her consent is that the Company will not be able to grant him or her awards under the Plan or administer or maintain awards. Therefore, the Participant understands that refusing or
withdrawing his or her consent may affect his or her ability to participate in the Plan (including the right to retain these RSUs). The Participant understands that he or she may contact his or her local human resources representative for more
information on the consequences of his or her refusal to consent or withdrawal of consent.

compliance of the Common Stock on any securities exchange or under any state, federal, or foreign law or the tax code and related regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a
condition to the issuance of Shares to the Participant (or his or her estate), the Company will try to meet the requirements of any such state, federal, or foreign law or securities exchange and to obtain any such consent or approval of any such

 EXHIBIT B 

APPENDIX TO RESTRICTED STOCK UNIT AGREEMENT 

Terms and Conditions 
 This Appendix to Restricted
Stock Unit Agreement (the “Appendix”) includes additional terms and conditions that govern these RSUs granted to the Participant under the Plan if he or she resides in one of the countries listed below on the Grant Date or he or she
moves to one of the listed countries. 
 Notifications 

This Appendix may also include information regarding exchange controls and certain other issues of which the Participant should be aware with respect to
participation in the Plan. The information is based on the securities, exchange control, and other Applicable Laws in effect in the respective countries as of
                    , 20    . Such Applicable Laws are often complex and change frequently. As a result, the Company strongly
recommends that the Participant not rely on the information in this Appendix as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Participant sells
Shares acquired under the Plan. 
 In addition, the information contained in this Appendix is general in nature and may not apply to the Participant’s
particular situation, and the Company is not in a position to assure him or her of a particular result. The Participant is advised to seek appropriate professional advice as to how the Applicable Laws in his or her country may apply to his or her
situation. 
 Finally, if the Participant is a citizen or resident of a country other than the one in which he or she is currently working, transfers
employment after these RSUs are granted, or is considered a resident of another country for local law purposes, the information in this Appendix may not apply to him or her, and the Administrator will determine to what extent the terms and
conditions in this Appendix apply.EX-10.3

 2015
EMPLOYEE STOCK PURCHASE PLAN 
 1. Purpose. The purpose of the Plan is to provide employees of the Company and its Designated
Companies with an opportunity to purchase Common Stock through accumulated Contributions. The Company intends for the Plan to have two components: a component intended to qualify as an “employee stock purchase plan” under Section 423
of the Code (the “423 Component”) and a component that is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code (the “Non-423 Component”). The provisions of the
423 Component 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. An option granted under the Non-423 Component will be
granted under rules, procedures, or sub-plans adopted by the Administrator designed to achieve tax, securities laws, or other objectives for Eligible Employees and the Company. Except as otherwise provided in the Plan, the Non-423 Component will
operate and be administered in the same manner as the 423 Component.

“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; provided that the acquisition of additional stock
by any one Person, who is considered to own more than 50% of the total voting power of the stock of the Company is not a Change in Control; or 

(ii) A change in the effective control of the Company, which occurs when 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; provided that if any Person is considered to be in effective control of the Company, the

 (iii) A change in the ownership of a substantial portion of the Company’s assets, which
occurs when 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; provided that the following will not constitute a change in the ownership of a substantial portion of the Company’s
assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company to: (1) a stockholder of the Company (immediately before the asset

considered terminated three 3 months and 1 day following the commencement of such leave. The Administrator has the discretion to determine (on a uniform and nondiscriminatory basis or as otherwise permitted by U.S. Treasury Regulation Section 1.423-2), prior to an Enrollment Date for all options to be granted on such Enrollment Date, whether the definition of Eligible Employee will or will not include an individual that: (i) has not

(d) Limitations. No Eligible Employee will be granted an option under the Plan (i) to the extent that, immediately after the

Registration Date and end on the last Trading Day on or before November 15, 2016 and the second Offering Period under the Plan will commence on the first Trading Day on or after May 15, 2016. The Administrator has the power to change the

(a) First Offering Period. An Eligible Employee will be entitled to continue to participate in the first Offering Period under

(i) no earlier than the effective date of the Form S-8 registration statement with respect to the issuance of Common Stock under this Plan and (ii) no later than 10 business days following the effective date of such S-8 registration
statement or such other date determined by the Administrator (the “Enrollment Window”). An Eligible Employee’s failure to submit the subscription agreement during the Enrollment Window will result in the automatic termination of the
Eligible Employee’s participation in the first Offering Period. 
 (b) Subsequent Offering Periods. An Eligible Employee may
participate in the Plan under Section 3(b) by (i) submitting to the Company’s stock administration office (or its designee) a properly completed subscription agreement authorizing Contributions in the form provided by the

6. Contributions. 
 (a)
When a Participant enrolls in the Plan under Section 5, he or she will elect to have Contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) 

  
 - 6 - 

 
made on each pay day during the Offering Period in an amount not exceeding 15% of the Compensation that he or she receives on the pay day (for illustrative purposes, if a pay day occurs on an
Exercise Date, a Participant’s payroll deductions on that day will be applied to his or her account under the then-current Purchase Period or Offering Period). The Administrator has the discretion to 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. A Participant’s subscription agreement will remain in effect
for successive Offering Periods unless terminated as provided in Section 10. 
 (b) If Contributions are made in the form of payroll
deductions, such payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day on or prior to the last Exercise Date of such Offering Period to which such authorization is
applicable, unless sooner terminated by the Participant under Section 10; provided, however, that for the first Offering Period, payroll deductions will commence on the first pay day on or following the end of the Enrollment Window. 

(c) All of a Participant’s Contributions will be credited to his or her account under the Plan, and Contributions will be made in whole
percentages of his or her Compensation only. The Participant may not make any additional payments into such account. 
 (d) A Participant
may discontinue his or her participation in the Plan as provided under Section 10. Unless otherwise determined by the Administrator, during a Purchase Period, a Participant may not increase the rate of his or her Contributions, but he or she
may (i) make a one-time decrease in the rate of his or her Contributions and/or (ii) stop making Contributions. Any such decrease or discontinuation during a Purchase Period or any change to the Participant’s rate of Contributions for
future Purchase Periods requires the Participant to (i) properly complete and submit to the Company’s stock administration office (or its designee) a new subscription agreement authorizing the change in Contribution rate in the form
provided by the Administrator for such purpose or (ii) follow an electronic or other procedure prescribed by the Administrator, in each case on or before a date determined by the Administrator prior to the applicable Exercise Date or Enrollment
Date, respectively. If the Participant has not followed such procedures to change the rate of Contributions or stop making Contributions, he or she will continue to make Contributions at the originally elected rate throughout the Purchase Period and
future Offering Periods and Purchase Periods (unless the Participant’s participation is terminated as provided in Sections 10 or 11). The Administrator has the discretion to amend the nature and/or number of Contribution rate changes that may
be made by Participants during any Offering Period or Purchase Period and may establish other conditions or limitations as it deems appropriate for Plan administration. Any change in Contribution rate or discontinuation of Contributions made under
this Section 6(d) will be effective as of the first full payroll period following 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). If a Participant stops making Contributions under this Section 6(d), he or she will be withdrawn from the Plan immediately after the exercise of his or her option on the applicable Exercise Date. 

(e) To the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(d), a Participant’s Contributions may be
decreased to zero percent at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 3(d) of the Plan, 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. 

  
 - 7 - 

 (f) 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, (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code, or
(iii) the Eligible Employees are participating in the Non-423 Component. 
 (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). 

7. 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 Employee’s account as of the Exercise Date by the applicable Purchase Price, up to a maximum of 4,000 shares of Common Stock (subject to any adjustment under Section 19) in each Purchase
Period and subject to the limitations in Sections 3(d) and 13. The Eligible Employee may accept the grant of such option (i) with respect to the first Offering Period by submitting a properly completed subscription agreement in accordance with
the requirements of Section 5 on or before the last day of the Enrollment Window, and (ii) with respect to any subsequent Offering Period under the Plan, by electing to participate in the Plan in accordance with the requirements of
Section 5. The Administrator may, for future Offering Periods, change the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Purchase Period or Offering Period. The option will expire on the last day of
the Offering Period. 
 8. 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 each 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 that are not sufficient to purchase a full share will be returned to the Participant. During a Participant’s lifetime, a
Participant’s option to purchase shares under the Plan 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

  
 - 8 - 

 
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
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 terminate any or all Offering Periods then in effect under Section 20. The Company may make a pro rata allocation of the shares available on the Enrollment Date of any applicable Offering
Period under the preceding sentence even if there is an authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date. 

9. 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 of the shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and under 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 has 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. 

10. Withdrawal. 
 (a) A
Participant may withdraw all but not less than all of 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 (which may be similar to the form attached to the Plan as Exhibit B) 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 on the first payroll date on or 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 on his or her eligibility to participate in any similar
plan adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws. 

11. Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be
withdrawn 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 to receive such Contributions under Section 15), and such Participant’s option will be automatically terminated. A Participant whose employment transfers between entities through a termination
with an 

  
 - 9 - 

 
immediate rehire (with no break in service) by the Company or a Designated Company will not be treated as terminated under the Plan; however, if a Participant transfers from an Offering under the
423 Component to the Non-423 Component, the exercise of the option will be qualified under the 423 Component only to the extent it complies with Section 423 of the Code. 

12. 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, will apply to all Participants in the relevant Offering under the 423 Component, except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f). 
 13. Stock. 

(a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19, the maximum number of shares of Common
Stock that will be made available for sale under the Plan will be 4,200,000 shares of Common Stock. The number of shares of Common Stock available for issuance under the Plan will be increased on the first day of each Fiscal Year beginning with the
2016 Fiscal Year equal to the least of (i) 8,400,000 shares of Common Stock, (ii) 1% of the outstanding shares of all classes of the Company’s common stock on the last day of the immediately preceding Fiscal Year, or (iii) an
amount determined by the Administrator. 
 (b) Until the shares of Common Stock 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 has only 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. 
 14. Administration. The Administrator has full
and exclusive discretionary authority to construe, interpret, and apply the terms of the Plan, to delegate ministerial duties to any of the Company’s employees, to designate separate Offerings under the Plan, to designate Affiliates and
Subsidiaries of the Company as participating in the 423 Component or Non-423 Component, 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., the terms of which
sub-plans may take precedence over other provisions of this Plan, with the exception of Section 13(a), but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan will govern the operation of such sub-plan).
Unless otherwise determined by the Administrator, the Eligible Employees eligible to participate in each sub-plan will participate in a separate Offering or in the Non-423 Component. 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 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. The Administrator also is authorized to determine that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of an option granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the

  
 - 10 - 

 
terms of options granted under the Plan or the same Offering to employees resident solely in the U.S. Every finding, decision, and determination made by the Administrator will, to the full extent
permitted by law, be final and binding upon all parties. 
 15. 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. 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). 

16. 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) 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. 

17. 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 or for Participants in the Non-423 Component for which Applicable Laws require that Contributions to the Plan by Participants be segregated from the Company’s
general corporate funds and/or deposited with an independent third party. Until shares of Common Stock are issued, Participants have only the rights of an unsecured creditor with respect to such shares. 

18. 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. 

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

  
 - 11 - 

 (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 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, 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. 
 (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 will 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. 

20. Amendment or Termination. 

(a) The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part of the Plan, 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 under 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 Applicable Laws, as further set forth in Section 12) 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 or Purchase 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 Contributions in 

  
 - 12 - 

 
excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed Contribution 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. 
 (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 the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any of its successors), including with respect to an Offering Period underway at the time; 

(ii) altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or Purchase Period underway at the
time of the change in Purchase Price; 
 (iii) shortening any Offering Period or Purchase Period by setting a New Exercise Date, including
an Offering Period or Purchase 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 of Common Stock 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 Participants. 
 21. Notices. All notices or other communications by a Participant to the Company under or in
connection with the Plan is 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 of such notices or other communications. 

22. 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 complies with all applicable provisions of law, domestic or foreign, including, without limitation, the U.S. Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated under such acts, 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. 

  
 - 13 - 

 23. Code Section 409A. The 423 Component of the Plan is exempt from the application
of Code Section 409A, and any ambiguities in the Plan will be interpreted to so that the Plan is exempt from Code Section 409A. 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 any
requirements necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B), but only to the extent any such amendments or action by the Administrator would not violate Code Section 409A. The Company has 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 Code Section 409A or compliant with any requirements necessary to avoid the imposition of additional tax under Code
Section 409A(a)(1)(B) is not so exempt or compliant or for any action taken by the Administrator with respect to such option. The Company makes no representation that the option to purchase Common Stock under the Plan complies with any
requirements necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B). 
 24. Term of Plan. The Plan
will become effective upon the later to occur of (a) its adoption by the Board or (b) the business day immediately prior to the Registration Date. It will continue in effect for a term of 20 years, unless sooner terminated under
Section 20. 
 25. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within 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. 

26. Governing Law. The Plan will be governed by, and construed in accordance with, the laws of the State of Delaware (except its
choice-of-law provisions). 
 27. No Right to Employment. Participation in the Plan by a Participant will not be construed as giving
a Participant the right to be retained as an employee of the Company or an Affiliate or Subsidiary of the Company, as applicable. Further, the Company or an Affiliate or Subsidiary of the Company may dismiss a Participant from employment at any
time, free from any liability or any claim under the Plan. 
 28. 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 will not affect the remaining parts of the Plan, and the Plan will be construed and enforced
as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included. 
 29. Compliance
with Applicable Laws. The terms of this Plan are intended to comply with all Applicable Laws and will be construed accordingly. 
 30.
Automatic Transfer to Low Price Offering Period. To the extent permitted by Applicable Laws, if the Fair Market Value on any Exercise Date in an Offering Period is lower than the Fair Market Value on the Enrollment Date of such Offering
Period, then all Participants in such Offering Period automatically will be 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 of such following Offering Period.
