 Exhibit 10.3 

CASTLIGHT HEALTH, INC. 

2014 EQUITY INCENTIVE PLAN 
 1.
PURPOSE. The purpose of this Plan is to provide incentives to attract, retain and motivate eligible persons whose present and potential contributions are important to the success of the Company, and any Parents and Subsidiaries that exist
now or in the future, by offering them an opportunity to participate in the Company’s future performance through the grant of Awards. Capitalized terms not defined elsewhere in the text are defined in Section 28. 

2. SHARES SUBJECT TO THE PLAN.  

2.1. Number of Shares Available. Subject to Sections 2.6 and 21 and any other applicable provisions hereof, the total number of
Shares reserved and available for grant and issuance pursuant to this Plan as of the date of adoption of the Plan by the Board, is fifteen million (15,000,000) Shares, plus (a) any reserved shares not issued or subject to outstanding
grants under the Company’s 2008 Stock Incentive Plan (the “Prior Plan”) on the Effective Date (as defined below), (b) shares that are subject to stock options or other awards granted under the Prior Plan that cease
to be subject to such stock options or other awards by forfeiture or otherwise after the Effective Date, (c) shares issued under the Prior Plan before or after the Effective Date pursuant to the exercise of stock options that are, after the
Effective Date, forfeited, (d) shares issued under the Prior Plan that are repurchased by the Company at the original issue price and (e) shares that are subject to stock options or other awards under the Prior Plan that are used to pay
the exercise price of an option or withheld to satisfy the tax withholding obligations related to any award. 
 2.2. Lapsed,
Returned Awards. Shares subject to Awards, and Shares issued under the Plan under any Award, will again be available for grant and issuance in connection with subsequent Awards under this Plan to the extent such Shares: (a) are subject to
issuance upon exercise of an Option or SAR granted under this Plan but which cease to be subject to the Option or SAR for any reason other than exercise of the Option or SAR; (b) are subject to Awards granted under this Plan that are forfeited
or are repurchased by the Company at the original issue price; (c) are subject to Awards granted under this Plan that otherwise terminate without such Shares being issued; or (d) are surrendered pursuant to an Exchange Program. To the
extent an Award under the Plan is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under the Plan. Shares used to pay the exercise price of an Award or withheld to satisfy
the tax withholding obligations related to an Award will become available for future grant or sale under the Plan. For the avoidance of doubt, Shares that otherwise become available for grant and issuance because of the provisions of this
Section 2.2 shall not include Shares subject to Awards that initially became available because of the substitution clause in Section 21.2 hereof. 

2.3. Minimum Share Reserve. At all times the Company shall reserve and keep available a sufficient number of Shares as shall be
required to satisfy the requirements of all outstanding Awards granted under this Plan. 
 2.4. Automatic Share Reserve
Increase. The number of Shares available for grant and issuance under the Plan shall be increased on January 1 of each of the calendar years 2015 through 2024, by the lesser of (a) five percent (5%) of the aggregate number of
shares of the Company’s Class A and Class B common stock issued and outstanding on each December 31 immediately prior to the date of increase or (b) such number of Shares determined by the Board; provided, however, that if on
January 1 of a calendar year, the Board has not either confirmed the five 

  
 1 

 
percent (5%) increase described in clause “(a)” of this paragraph or approved an increase of a lesser number of Shares for such calendar year, then the Board shall be deemed to
have waived the automatic increase provided for by this paragraph, and no such increase shall occur for such calendar year. 
 2.5.
Limitations. No more than fifty-five million (55,000,000) Shares shall be issued pursuant to the exercise of ISOs. 

2.6. Adjustment of Shares. If the number of outstanding Shares is changed by a stock dividend, recapitalization, stock split,
reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of the Company, without consideration, then (a) the number of Shares reserved for issuance and future grant under the Plan set forth in
Section 2.1, including shares reserved under sub-clauses (a)-(e) of Section 2.1, (b) the Exercise Prices of and number of Shares subject to outstanding Options and SARs, (c) the number of Shares subject to other outstanding
Awards, (d) the maximum number of shares that may be issued as ISOs set forth in Section 2.5, (e) the maximum number of Shares that may be issued to an individual or to a new Employee in any one calendar year set forth in
Section 3 and (f) the number of Shares that may be granted as Awards to Non-Employee Directors as set forth in Section 12, shall be proportionately adjusted, subject to any required action by the Board or the stockholders of the
Company and in compliance with applicable securities laws; provided that fractions of a Share will not be issued. 
 3. ELIGIBILITY. ISOs may
be granted only to Employees. All other Awards may be granted to Employees, Consultants, Directors and Non-Employee Directors; provided such Consultants, Directors and Non-Employee Directors render bona fide services not in connection with
the offer and sale of securities in a capital-raising transaction. No Participant will be eligible to receive more than five million (5,000,000) Shares in any calendar year under this Plan pursuant to the grant of Awards except that new
Employees are eligible to receive up to a maximum of ten million (10,000,000) Shares in the calendar year in which they commence their employment. 

4. ADMINISTRATION. 

4.1. Committee Composition; Authority. This Plan will be administered by the Committee or by the Board acting as the Committee.
Subject to the general purposes, terms and conditions of this Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan. The Committee will have the authority to: 

(a) construe and interpret this Plan, any Award Agreement and any other agreement or document executed pursuant to this Plan;

 (b) prescribe, amend and rescind rules and regulations relating to this Plan or any Award; 

(c) select persons to receive Awards; 

(d) determine the form and terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder.
Such terms and conditions include, but are not limited to, the exercise price, the time or times when Awards may vest and be exercised (which may be based on performance criteria) or settled, any vesting acceleration or waiver of forfeiture
restrictions, the method to satisfy tax withholding obligations or any other tax liability legally due and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Committee will
determine; 

  
 2 

 (e) determine the number of Shares or other consideration subject to Awards; 

(f) determine the Fair Market Value in good faith and interpret the applicable provisions of this Plan and the definition of
Fair Market Value in connection with circumstances that impact the Fair Market Value, if necessary; 
 (g) determine whether
Awards will be granted singly, in combination with, in tandem with, in replacement of, or as alternatives to, other Awards under this Plan or any other incentive or compensation plan of the Company or any Parent or Subsidiary of the Company; 

(h) grant waivers of Plan or Award conditions; 

(i) determine the vesting, exercisability and payment of Awards; 

(j) correct any defect, supply any omission or reconcile any inconsistency in this Plan, any Award or any Award Agreement; 

(k) determine whether an Award has been earned; 

(l) determine the terms and conditions of any, and to institute any Exchange Program; 

(m) reduce or waive any criteria with respect to Performance Factors; 

(n) adjust Performance Factors to take into account changes in law and accounting or tax rules as the Committee deems necessary
or appropriate to reflect the impact of extraordinary or unusual items, events or circumstances to avoid windfalls or hardships provided that such adjustments are consistent with the regulations promulgated under Section 162(m) of the Code with
respect to persons whose compensation is subject to Section 162(m) of the Code; 
 (o) adopt rules and/or procedures
(including the adoption of any subplan under this Plan) relating to the operation and administration of the Plan to accommodate requirements of local law and procedures outside of the United States; 

(p) make all other determinations necessary or advisable for the administration of this Plan; and 

(q) delegate any of the foregoing to a subcommittee consisting of one or more executive officers pursuant to a specific
delegation as permitted by applicable law, including Section 157(c) of the Delaware General Corporation Law. 
 4.2.
Committee Interpretation and Discretion. Any determination made by the Committee with respect to any Award shall be made in its sole discretion at the time of grant of the Award or, unless in contravention of any express term of the
Plan or Award, at any later time, and such determination shall be final and binding on the Company and all persons having an interest in any Award under the Plan. Any dispute regarding the interpretation of the Plan or any Award Agreement shall be
submitted by the Participant or Company to the Committee for review. The resolution of such a dispute by the Committee shall be final and binding on the Company and the Participant. The Committee may delegate to one or more executive officers the
authority to review and resolve disputes with respect to Awards held by Participants who are not Insiders, and such resolution shall be final and binding on the Company and the Participant. 

  
 3 

 4.3. Section 162(m) of the Code and Section 16 of the Exchange Act. When
necessary or desirable for an Award to qualify as “performance-based compensation” under Section 162(m) of the Code the Committee shall include at least two persons who are “outside directors” (as defined under
Section 162(m) of the Code) and at least two (or a majority if more than two then serve on the Committee) such “outside directors” shall approve the grant of such Award and timely determine (as applicable) the Performance Period and
any Performance Factors upon which vesting or settlement of any portion of such Award is to be subject. When required by Section 162(m) of the Code, prior to settlement of any such Award at least two (or a majority if more than two then serve
on the Committee) such “outside directors” then serving on the Committee shall determine and certify in writing the extent to which such Performance Factors have been timely achieved and the extent to which the Shares subject to such Award
have thereby been earned. Awards granted to Participants who are subject to Section 16 of the Exchange Act must be approved by two or more “non-employee directors” (as defined in the regulations promulgated under Section 16 of
the Exchange Act). With respect to Participants whose compensation is subject to Section 162(m) of the Code, and provided that such adjustments are consistent with the regulations promulgated under Section 162(m) of the Code, the Committee
may adjust the performance goals to account for changes in law and accounting and to make such adjustments as the Committee deems necessary or appropriate to reflect the impact of extraordinary or unusual items, events or circumstances to avoid
windfalls or hardships, including without limitation (a) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring charges, (b) an event either not directly related to the operations of the Company or
not within the reasonable control of the Company’s management, or (c) a change in accounting standards required by generally accepted accounting principles. 

4.4. Documentation. The Award Agreement for a given Award, the Plan and any other documents may be delivered to, and accepted
by, a Participant or any other person in any manner (including electronic distribution or posting) that meets applicable legal requirements. 

4.5. Foreign Award Recipients. Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws in
other countries in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Committee, in its sole discretion, shall have the power and authority to: (a) determine which Subsidiaries shall
be covered by the Plan; (b) determine which individuals outside the United States are eligible to participate in the Plan; (c) modify the terms and conditions of any Award granted to individuals outside the United States to comply with
applicable foreign laws; (d) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Committee determines such actions to be necessary or advisable (and such subplans and/or modifications shall be
attached to this Plan as appendices); provided, however, that no such subplans and/or modifications shall increase the share limitations contained in Section 2.1 hereof; and (e) take any action, before or after an Award is made, that the
Committee determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. Notwithstanding the foregoing, the Committee may not take any actions hereunder, and no Awards shall be
granted, that would violate the Exchange Act or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law. 

5. OPTIONS. An Option is the right but not the obligation to purchase a Share, subject to certain conditions, if applicable. The Committee may
grant Options to eligible Employees, Consultants and Directors and will determine whether such Options will be Incentive Stock Options within the meaning of the Code (“ISOs”) or Nonqualified Stock Options
(“NSOs”), the number of Shares subject to the Option, the Exercise Price of the Option, the period during which the Option may vest and be exercised, and all other terms and conditions of the Option, subject to the following
terms of this section. 

  
 4 

 5.1. Option Grant. Each Option granted under this Plan will identify the Option as
an ISO or an NSO. An Option may be, but need not be, awarded upon satisfaction of such Performance Factors during any Performance Period as are set out in advance in the Participant’s individual Award Agreement. If the Option is being earned
upon the satisfaction of Performance Factors, then the Committee will: (a) determine the nature, length and starting date of any Performance Period for each Option; and (b) select from among the Performance Factors to be used to measure
the performance, if any. Performance Periods may overlap and Participants may participate simultaneously with respect to Options that are subject to different performance goals and other criteria. 

5.2. Date of Grant. The date of grant of an Option will be the date on which the Committee makes the determination to grant such
Option, or a specified future date. The Award Agreement will be delivered to the Participant within a reasonable time after the granting of the Option. 

5.3. Exercise Period. Options may be vested and exercisable within the times or upon the conditions as set forth in the Award
Agreement governing such Option; provided, however, that no Option will be exercisable after the expiration of ten (10) years from the date the Option is granted; and provided further that no ISO granted to a person who, at
the time the ISO is granted, directly or by attribution owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of any Parent or Subsidiary of the Company (“Ten Percent
Stockholder”) will be exercisable after the expiration of five (5) years from the date the ISO is granted. The Committee also may provide for Options to become exercisable at one time or from time to time, periodically or
otherwise, in such number of Shares or percentage of Shares as the Committee determines. 
 5.4. Exercise Price. The Exercise
Price of an Option will be determined by the Committee when the Option is granted; provided that: (a) the Exercise Price of an Option will be not less than one hundred percent (100%) of the Fair Market Value of the Shares on the date of
grant and (b) the Exercise Price of any ISO granted to a Ten Percent Stockholder will not be less than one hundred ten percent (110%) of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased may be made
in accordance with Section 11 and the Award Agreement and in accordance with any procedures established by the Company. 
 5.5.
Method of Exercise. Any Option granted hereunder will be vested and exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Committee and set forth in the Award Agreement. An Option
may not be exercised for a fraction of a Share. An Option will be deemed exercised when the Company receives: (a) notice of exercise (in such form as the Committee may specify from time to time) from the person entitled to exercise the Option,
and (b) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Full payment may consist of any consideration and method of payment authorized by the Committee and permitted by the
Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly
after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 2.6 of the Plan. Exercising an Option in any manner will
decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 

5.6. Termination of Service. If the Participant’s Service terminates for any reason except for Cause or the
Participant’s death or Disability, then the Participant may exercise such Participant’s Options only to the extent that such Options would have been exercisable by the 

  
 5 

 
Participant on the date Participant’s Service terminates no later than three (3) months after the date Participant’s Service terminates (or such shorter or longer time period as
may be determined by the Committee, with any exercise beyond three (3) months after the date Participant’s Service terminates deemed to be the exercise of an NSO), but in any event no later than the expiration date of the Options. 

(a) Death. If the Participant’s Service terminates because of the Participant’s death (or the Participant dies
within three (3) months after Participant’s Service terminates other than for Cause or because of the Participant’s Disability), then the Participant’s Options may be exercised only to the extent that such Options would have been
exercisable by the Participant on the date Participant’s Service terminates and must be exercised by the Participant’s legal representative, or authorized assignee, no later than twelve (12) months after the date Participant’s
Service terminates (or such shorter or longer time period as may be determined by the Committee), but in any event no later than the expiration date of the Options. 

(b) Disability. If the Participant’s Service terminates because of the Participant’s Disability, then the
Participant’s Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the date Participant’s Service terminates and must be exercised by the Participant (or the Participant’s
legal representative or authorized assignee) no later than twelve (12) months after the date Participant’s Service terminates (or such shorter or longer time period as may be determined by the Committee, with any exercise beyond
(a) three (3) months after the date Participant’s Service terminates when the termination of Service is for a Disability that is not a “permanent and total disability” as defined in Section 22(e)(3) of the Code, or
(b) twelve (12) months after the date Participant’s Service terminates when the termination of Service is for a Disability that is a “permanent and total disability” as defined in Section 22(e)(3) of the Code, deemed to
be exercise of an NSO), but in any event no later than the expiration date of the Options. 
 (c) Cause. If the
Participant is terminated for Cause, then Participant’s Options shall expire on such Participant’s date of termination of Service, or at such later time and on such conditions as are determined by the Committee, but in any no event later
than the expiration date of the Options. Unless otherwise provided in the Award Agreement, Cause shall have the meaning set forth in the Plan. 

5.7. Limitations on Exercise. The Committee may specify a minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent any Participant from exercising the Option for the full number of Shares for which it is then exercisable. 

5.8. Limitations on ISOs. With respect to Awards granted as ISOs, to the extent that the aggregate Fair Market Value of the
Shares with respect to which such ISOs are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such Options will be
treated as NSOs. For purposes of this Section 5.8, ISOs will be taken into account in the order in which they were granted. The Fair Market Value of the Shares will be determined as of the time the Option with respect to such Shares is granted.
In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, such different limit will be automatically
incorporated herein and will apply to any Options granted after the effective date of such amendment. 
 5.9. Modification,
Extension or Renewal. The Committee may modify, extend or renew outstanding Options and authorize the grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any
of 

  
 6 

 
such Participant’s rights under any Option previously granted. Any outstanding ISO that is modified, extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code. Subject to Section 18 of this Plan, by written notice to affected Participants, the Committee may reduce the Exercise Price of outstanding Options without the consent of such Participants; provided,
however, that the Exercise Price may not be reduced below the Fair Market Value on the date the action is taken to reduce the Exercise Price. 

5.10. No Disqualification. Notwithstanding any other provision in this Plan, no term of this Plan relating to ISOs will be
interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the consent of the Participant affected, to disqualify any ISO
under Section 422 of the Code. 
 6. RESTRICTED STOCK AWARDS. A Restricted Stock Award is an offer by the Company to sell to an eligible
Employee, Consultant, or Director Shares that are subject to restrictions (“Restricted Stock”). The Committee will determine to whom an offer will be made, the number of Shares the Participant may purchase, the
Purchase Price, the restrictions under which the Shares will be subject and all other terms and conditions of the Restricted Stock Award, subject to the Plan. 

6.1. Restricted Stock Purchase Agreement. All purchases under a Restricted Stock Award will be evidenced by an Award
Agreement. Except as may otherwise be provided in an Award Agreement, a Participant accepts a Restricted Stock Award by signing and delivering to the Company an Award Agreement with full payment of the Purchase Price, within thirty (30) days
from the date the Award Agreement was delivered to the Participant. If the Participant does not accept such Award within thirty (30) days, then the offer of such Restricted Stock Award will terminate, unless the Committee determines otherwise.

 6.2. Purchase Price. The Purchase Price for a Restricted Stock Award will be determined by the Committee and may be
less than Fair Market Value on the date the Restricted Stock Award is granted. Payment of the Purchase Price must be made in accordance with Section 11 of the Plan, and the Award Agreement and in accordance with any procedures established by
the Company. 
 6.3. Terms of Restricted Stock Awards. Restricted Stock Awards will be subject to such restrictions as the
Committee may impose or are required by law. These restrictions may be based on completion of a specified number of years of service with the Company or upon completion of Performance Factors, if any, during any Performance Period as set out in
advance in the Participant’s Award Agreement. Prior to the grant of a Restricted Stock Award, the Committee shall: (a) determine the nature, length and starting date of any Performance Period for the Restricted Stock Award; (b) select
from among the Performance Factors to be used to measure performance goals, if any; and (c) determine the number of Shares that may be awarded to the Participant. Performance Periods may overlap and a Participant may participate simultaneously
with respect to Restricted Stock Awards that are subject to different Performance Periods and having different performance goals and other criteria. 

6.4. Termination of Service. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such date
Participant’s Service terminates (unless determined otherwise by the Committee). 

  
 7 

 7. STOCK BONUS AWARDS. A Stock Bonus Award is an award to an eligible Employee, Consultant, or
Director of Shares for Services to be rendered or for past Services already rendered to the Company or any Parent or Subsidiary. All Stock Bonus Awards shall be made pursuant to an Award Agreement. No payment from the Participant will be required
for Shares awarded pursuant to a Stock Bonus Award. 
 7.1. Terms of Stock Bonus Awards. The Committee will determine the
number of Shares to be awarded to the Participant under a Stock Bonus Award and any restrictions thereon. These restrictions may be based upon completion of a specified number of years of service with the Company or upon satisfaction of performance
goals based on Performance Factors during any Performance Period as set out in advance in the Participant’s Stock Bonus Agreement. Prior to the grant of any Stock Bonus Award the Committee shall: (a) determine the nature, length and
starting date of any Performance Period for the Stock Bonus Award; (b) select from among the Performance Factors to be used to measure performance goals; and (c) determine the number of Shares that may be awarded to the Participant.
Performance Periods may overlap and a Participant may participate simultaneously with respect to Stock Bonus Awards that are subject to different Performance Periods and different performance goals and other criteria. 

7.2. Form of Payment to Participant. Payment may be made in the form of cash, whole Shares, or a combination thereof, based on
the Fair Market Value of the Shares earned under a Stock Bonus Award on the date of payment, as determined in the sole discretion of the Committee. 

7.3. Termination of Service. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such date
Participant’s Service terminates (unless determined otherwise by the Committee). 
 8. STOCK APPRECIATION RIGHTS. A Stock Appreciation
Right (“SAR”) is an award to an eligible Employee, Consultant, or Director that may be settled in cash, or Shares (which may consist of Restricted Stock), having a value equal to (a) the difference between the Fair
Market Value on the date of exercise over the Exercise Price multiplied by (b) the number of Shares with respect to which the SAR is being settled (subject to any maximum number of Shares that may be issuable as specified in an Award
Agreement). All SARs shall be made pursuant to an Award Agreement. 
 8.1. Terms of SARs. The Committee will determine the
terms of each SAR including, without limitation: (a) the number of Shares subject to the SAR; (b) the Exercise Price and the time or times during which the SAR may be settled; (c) the consideration to be distributed on settlement of
the SAR; and (d) the effect of the Participant’s termination of Service on each SAR. The Exercise Price of the SAR will be determined by the Committee when the SAR is granted, and may not be less than Fair Market Value. A SAR may be
awarded upon satisfaction of Performance Factors, if any, during any Performance Period as are set out in advance in the Participant’s individual Award Agreement. If the SAR is being earned upon the satisfaction of Performance Factors, then the
Committee will: (x) determine the nature, length and starting date of any Performance Period for each SAR; and (y) select from among the Performance Factors to be used to measure the performance, if any. Performance Periods may overlap and
Participants may participate simultaneously with respect to SARs that are subject to different Performance Factors and other criteria. 

8.2. Exercise Period and Expiration Date. A SAR will be exercisable within the times or upon the occurrence of events determined
by the Committee and set forth in the Award Agreement governing such SAR. The SAR Agreement shall set forth the expiration date; provided that no SAR will be exercisable after the expiration of ten (10) years from the date the SAR is granted.
The Committee may also provide for SARs to become exercisable at one time or from time to time, periodically or otherwise (including, without limitation, upon the attainment during a Performance Period of performance goals based on Performance
Factors), in such number of Shares or percentage of the Shares subject to the SAR as the Committee 

  
 8 

 
determines. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on the date Participant’s Service terminates (unless determined otherwise by the Committee).
Notwithstanding the foregoing, the rules of Section 5.6 also will apply to SARs. 
 8.3. Form of Settlement. Upon
exercise of a SAR, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying (a) the difference between the Fair Market Value of a Share on the date of exercise over the Exercise Price; times
(b) the number of Shares with respect to which the SAR is exercised. At the discretion of the Committee, the payment from the Company for the SAR exercise may be in cash, in Shares of equivalent value, or in some combination thereof. The
portion of a SAR being settled may be paid currently or on a deferred basis with such interest or dividend equivalent, if any, as the Committee determines, provided that the terms of the SAR and any deferral satisfy the requirements of
Section 409A of the Code. 
 8.4. Termination of Service. Except as may be set forth in the Participant’s Award
Agreement, vesting ceases on such date Participant’s Service terminates (unless determined otherwise by the Committee). 
 9. RESTRICTED STOCK
UNITS. A Restricted Stock Unit (“RSU”) is an award to an eligible Employee, Consultant, or Director covering a number of Shares that may be settled in cash, or by issuance of those Shares (which may consist of
Restricted Stock). All RSUs shall be made pursuant to an Award Agreement. 
 9.1. Terms of RSUs. The Committee will determine
the terms of an RSU including, without limitation: (a) the number of Shares subject to the RSU; (b) the time or times during which the RSU may be settled; (c) the consideration to be distributed on settlement; and (d) the effect
of the Participant’s termination of Service on each RSU. An RSU may be awarded upon satisfaction of such performance goals based on Performance Factors during any Performance Period as are set out in advance in the Participant’s Award
Agreement. If the RSU is being earned upon satisfaction of Performance Factors, then the Committee will: (x) determine the nature, length and starting date of any Performance Period for the RSU; (y) select from among the Performance
Factors to be used to measure the performance, if any; and (z) determine the number of Shares deemed subject to the RSU. Performance Periods may overlap and participants may participate simultaneously with respect to RSUs that are subject to
different Performance Periods and different performance goals and other criteria. 
 9.2. Form and Timing of Settlement.
Payment of earned RSUs shall be made as soon as practicable after the date(s) determined by the Committee and set forth in the Award Agreement. The Committee, in its sole discretion, may settle earned RSUs in cash, Shares, or a combination of both.
The Committee may also permit a Participant to defer payment under a RSU to a date or dates after the RSU is earned provided that the terms of the RSU and any deferral satisfy the requirements of Section 409A of the Code. 

9.3. Termination of Service. Except as may be set forth in the Participant’s Award Agreement, vesting ceases on such date
Participant’s Service terminates (unless determined otherwise by the Committee). 

  
 9 

 10. PERFORMANCE AWARDS. A Performance Award is an award to an eligible Employee, Consultant, or
Director of a cash bonus or an award of Performance Shares denominated in Shares that may be settled in cash, or by issuance of those Shares (which may consist of Restricted Stock). Grants of Performance Awards shall be made pursuant to an Award
Agreement. 
 10.1. Terms of Performance Shares. The Committee will determine, and each Award Agreement shall set forth, the
terms of each Performance Award including, without limitation: (a) the amount of any cash bonus, (b) the number of Shares deemed subject to an award of Performance Shares; (c) the Performance Factors and Performance Period that shall
determine the time and extent to which each award of Performance Shares shall be settled; (d) the consideration to be distributed on settlement, and (e) the effect of the Participant’s termination of Service on each Performance Award.
In establishing Performance Factors and the Performance Period the Committee will: (x) determine the nature, length and starting date of any Performance Period; (y) select from among the Performance Factors to be used; and
(z) determine the number of Shares deemed subject to the award of Performance Shares. Prior to settlement the Committee shall determine the extent to which Performance Awards have been earned. Performance Periods may overlap and Participants
may participate simultaneously with respect to Performance Awards that are subject to different Performance Periods and different performance goals and other criteria. No Participant will be eligible to receive more than ten million dollars
($10,000,000) in Performance Awards in any calendar year under this Plan. 
 10.2. Value, Earning and Timing of Performance
Shares. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. After the applicable Performance Period has ended, the holder of Performance Shares will be entitled to receive a payout of
the number of Performance Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding Performance Factors or other vesting provisions have been achieved. The Committee, in its
sole discretion, may pay earned Performance Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Shares at the close of the applicable Performance Period) or in a combination
thereof. 
 10.3. Termination of Service. Except as may be set forth in the Participant’s Award Agreement, vesting ceases
on the date Participant’s Service terminates (unless determined otherwise by the Committee).

 12. GRANTS TO NON-EMPLOYEE DIRECTORS. Non-Employee Directors are eligible to receive any type of
Award offered under this Plan except ISOs. Awards pursuant to this Section 12 may be automatically made pursuant to policy adopted by the Board, or made from time to time as determined in the discretion of the Board. The aggregate number of
Shares subject to Awards granted to a Non-Employee Director pursuant to this Section 12 in any calendar year shall not exceed one million (1,000,000). 

12.1. Eligibility. Awards pursuant to this Section 12 shall be granted only to Non-Employee Directors. A Non-Employee
Director who is elected or re-elected as a member of the Board will be eligible to receive an Award under this Section 12. 
 12.2.
Vesting, Exercisability and Settlement. Except as set forth in Section 21, Awards shall vest, become exercisable and be settled as determined by the Board. With respect to Options and SARs, the exercise price granted to Non-Employee
Directors shall not be less than the Fair Market Value of the Shares at the time that such Option or SAR is granted. 
 12.3.
Election to receive Awards in Lieu of Cash. A Non-Employee Director may elect to receive his or her annual retainer payments and/or meeting fees from the Company in the form of cash or Awards or a combination thereof, as determined by the
Committee. Such Awards shall be issued under the Plan. An election under this Section 12.3 shall be filed with the Company on the form prescribed by the Company. 

13. WITHHOLDING TAXES. 

13.1. Withholding Generally. Whenever Shares are to be issued in satisfaction of Awards granted under this Plan or the
applicable tax event occurs, the Company may require the Participant to remit to the Company, or to the Parent or Subsidiary employing the Participant, an amount sufficient to satisfy applicable U.S. federal, state, local and international
withholding tax requirements or any other tax liability legally due from the Participant prior to the delivery of Shares pursuant to exercise or settlement of any Award. Whenever payments in satisfaction of Awards granted under this Plan are to be
made in cash, such payment will be net of an amount sufficient to satisfy applicable U.S. federal, state, local and international withholding tax requirements or any other tax liability legally due from the Participant. The Fair Market Value of
the Shares will be determined as of the date that the taxes are required to be withheld and such Shares will be valued based on the value of the actual trade or, if there is none, the Fair Market Value of the Shares as of the previous trading day.

 13.2. Stock Withholding. The Committee, or its delegate(s), as permitted by applicable law, in its sole discretion and
pursuant to such procedures as it may specify from time to time and to limitations of local law, may require or permit a Participant to satisfy such tax withholding obligation or any other tax liability legally due from the Participant, in whole or
in part by (without limitation) (a) paying cash, (b) electing to have the Company withhold otherwise deliverable cash or Shares having a Fair Market Value equal to the minimum statutory amount required to be withheld, (c) delivering
to the Company already-owned Shares having a Fair Market Value equal to the minimum amount required to be withheld or (d) withholding from proceeds of the sale of otherwise deliverable Shares acquired pursuant to an Award either through a
voluntary sale or through a mandatory sale arranged by the Company. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 

14. TRANSFERABILITY.  

14.1. Transfer Generally. Unless determined otherwise by the Committee or pursuant to Section 14.2, 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. If the Committee makes an Award transferable, including, without limitation, by instrument to an inter

  
 11 

 
vivos or testamentary trust in which the Awards are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift or by domestic relations order to a Permitted Transferee, such
Award will contain such additional terms and conditions as the Committee deems appropriate. All Awards shall be exercisable: (a) during the Participant’s lifetime only by (i) the Participant, or (ii) the Participant’s
guardian or legal representative; (b) after the Participant’s death, by the legal representative of the Participant’s heirs or legatees; and (c) in the case of all awards except ISOs, by a Permitted Transferee. 

14.2. Award Transfer Program. Notwithstanding any contrary provision of the Plan, the Committee shall have all discretion and
authority to determine and implement the terms and conditions of any Award Transfer Program instituted pursuant to this Section 14.2 and shall have the authority to amend the terms of any Award participating, or otherwise eligible to
participate in, the Award Transfer Program, including (but not limited to) the authority to (a) amend (including to extend) the expiration date, post-termination exercise period and/or forfeiture conditions of any such Award, (b) amend or
remove any provisions of the Award relating to the Award holder’s continued service to the Company or its Parent or any Subsidiary, (c) amend the permissible payment methods with respect to the exercise or purchase of any such Award,
(d) amend the adjustments to be implemented in the event of changes in the capitalization and other similar events with respect to such Award, and (e) make such other changes to the terms of such Award as the Committee deems necessary or
appropriate in its sole discretion. 
 15. PRIVILEGES OF STOCK OWNERSHIP; RESTRICTIONS ON SHARES. 

15.1. Voting and Dividends. No Participant will have any of the rights of a stockholder with respect to any Shares until the
Shares are issued to the Participant, except for any dividend equivalent rights permitted by an applicable Award Agreement. After Shares are issued to the Participant, the Participant will be a stockholder and have all the rights of a stockholder
with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares; provided, that if such Shares are Restricted Stock, then any new, additional or different
securities the Participant may become entitled to receive with respect to such Shares by virtue of a stock dividend, stock split or any other change in the corporate or capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to retain such stock dividends or stock distributions with respect to Shares that are repurchased at the Participant’s Purchase Price or Exercise Price,
as the case may be, pursuant to Section 15.2. 
 15.2. Restrictions on Shares. At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) a right to repurchase (a “Right of Repurchase”) a portion of any or all Unvested Shares held by a Participant following such Participant’s termination of Service at
any time within ninety (90) days (or such longer or shorter time determined by the Committee) after the later of the date Participant’s Service terminates and the date the Participant purchases Shares under this Plan, for cash and/or
cancellation of purchase money indebtedness, at the Participant’s Purchase Price or Exercise Price, as the case may be. 
 16.
CERTIFICATES. All Shares or other securities whether or not certificated, delivered under this Plan will be subject to such stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including
restrictions under any applicable U.S. federal, state or foreign securities law, or any rules, regulations and other requirements of the SEC or any stock exchange or automated quotation system upon which the Shares may be listed or quoted and any
non-U.S. exchange controls or securities law restrictions to which the Shares are subject. 

  
 12 

 17. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a Participant’s Shares, the
Committee may require the Participant to deposit all certificates representing Shares, together with stock powers or other instruments of transfer approved by the Committee, appropriately endorsed in blank, with the Company or an agent designated by
the Company to hold in escrow until such restrictions have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions to be placed on the certificates. Any Participant who is permitted to execute a promissory
note as partial or full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so purchased as collateral to secure the payment of the Participant’s obligation
to the Company under the promissory note; provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of such obligation and, in any event, the Company will have full
recourse against the Participant under the promissory note notwithstanding any pledge of the Participant’s Shares or other collateral. In connection with any pledge of the Shares, the Participant will be required to execute and deliver a
written pledge agreement in such form as the Committee will from time to time approve. The Shares purchased with the promissory note may be released from the pledge on a pro rata basis as the promissory note is paid. 

18. REPRICING; EXCHANGE AND BUYOUT OF AWARDS. Without prior stockholder approval the Committee may (a) reprice Options or SARs(and where
such repricing is a reduction in the Exercise Price of outstanding Options or SARs, the consent of the affected Participants is not required provided written notice is provided to them, notwithstanding any adverse tax consequences to them arising
from the repricing), and (b) with the consent of the respective Participants (unless not required pursuant to Section 5.9 of the Plan), pay cash or issue new Awards in exchange for the surrender and cancellation of any, or all, outstanding
Awards. 
 19. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award will not be effective unless such Award is in compliance with all
applicable U.S. and foreign federal and state securities and exchange control laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed or
quoted, as they are in effect on the date of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or deliver certificates for Shares
under this Plan prior to: (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable; and/or (b) completion of any registration or other qualification of such Shares under any state or
federal or foreign law or ruling of any governmental body that the Company determines to be necessary or advisable. The Company will be under no obligation to register the Shares with the SEC or to effect compliance with the registration,
qualification or listing requirements of any foreign or state securities laws, exchange control laws, stock exchange or automated quotation system, and the Company will have no liability for any inability or failure to do so. 

20. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted under this Plan will confer or be deemed to confer on any Participant any
right to continue in the employ of, or to continue any other relationship with, the Company or any Parent or Subsidiary of the Company or limit in any way the right of the Company or any Parent or Subsidiary of the Company to terminate
Participant’s employment or other relationship at any time. 
 21. CORPORATE TRANSACTIONS. 

21.1. Assumption or Replacement of Awards by Successor. In the event of a Corporate Transaction any or
all outstanding Awards may be assumed or replaced by the successor corporation, which assumption or replacement shall be binding on all Participants. In the alternative, the successor corporation may substitute equivalent Awards or provide
substantially similar consideration to Participants as was provided to stockholders (after taking into account the existing provisions of the Awards). The successor corporation may also issue, 

  
 13 

 
in place of outstanding Shares of the Company held by the Participant, substantially similar shares or other property subject to repurchase restrictions no less favorable to the Participant. In
the event such successor or acquiring corporation (if any) refuses to assume, convert, replace or substitute Awards, as provided above, pursuant to a Corporate Transaction, then notwithstanding any other provision in this Plan to the contrary, such
Awards shall have their vesting accelerate as to all shares subject to such Award (and any applicable right of repurchase fully lapse) immediately prior to the Corporate Transaction. Further, in the event such successor or acquiring corporation (if
any) refuses to assume, convert, replace or substitute Awards, as provided above, pursuant to a Corporate Transaction, the Committee will notify the Participant in writing or electronically that such Award will be exercisable for a period of time
determined by the Committee in its sole discretion, and such Award will terminate upon the expiration of such period. In addition, following a Corporate Transaction, 100% of the total number of Shares subject to each time-based Award held by an
Employee shall become vested if the Employee’s employment is terminated by the Company without Cause or by the Employee for Good Reason during the period beginning on the date that is three (3) months prior to the Corporate Transaction and
ending on the twelve (12) month anniversary of the Corporate Transaction; it being understood that the vesting acceleration set forth in the preceding clause is in addition to vesting of the Shares that has occurred prior to the termination of
employment without Cause or for Good Reason. Awards need not be treated similarly in a Corporate Transaction. 
 21.2. Assumption
of Awards by the Company. The Company, from time to time, also may substitute or assume outstanding awards granted by another company, whether in connection with an acquisition of such other company or otherwise, by either; (a) granting an
Award under this Plan in substitution of such other company’s award; or (b) assuming such award as if it had been granted under this Plan if the terms of such assumed award could be applied to an Award granted under this Plan. Such
substitution or assumption will be permissible if the holder of the substituted or assumed award would have been eligible to be granted an Award under this Plan if the other company had applied the rules of this Plan to such grant. In the event the
Company assumes an award granted by another company, the terms and conditions of such award will remain unchanged (except that the Purchase Price or the Exercise Price, as the case may be, and the number and nature of Shares issuable upon
exercise or settlement of any such Award will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option in substitution rather than assuming an existing option, such new Option may
be granted with a similarly adjusted Exercise Price. Substitute Awards shall not reduce the number of Shares authorized for grant under the Plan or authorized for grant to a Participant in a calendar year. 

21.3. Non-Employee Directors’ Awards. Notwithstanding any provision to the contrary herein, in the event of a Corporate
Transaction, the vesting of all Awards granted to Non-Employee Directors shall accelerate and such Awards shall become exercisable (as applicable) in full prior to the consummation of such event at such times and on such conditions as the Committee
determines. 
 22. ADOPTION AND STOCKHOLDER APPROVAL. This Plan shall be submitted for the approval of the Company’s stockholders,
consistent with applicable laws, within twelve (12) months before or after the date this Plan is adopted by the Board. 
 23. TERM OF
PLAN/GOVERNING LAW. Unless earlier terminated as provided herein, this Plan will become effective on the Effective Date and will terminate ten (10) years from the date this Plan is adopted by the Board. This Plan and all Awards granted
hereunder shall be governed by and construed in accordance with the laws of the State of Delaware (excluding its conflict of law rules). 

  
 14 

 24. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time terminate or amend this Plan in any
respect, including, without limitation, amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan; provided, however, that the Board will not, without the approval of the stockholders of the Company,
amend this Plan in any manner that requires such stockholder approval; provided further, that a Participant’s Award shall be governed by the version of this Plan then in effect at the time such Award was granted. 

25. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by the Board, the submission of this Plan to the stockholders of the Company
for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem desirable, including, without limitation, the granting of stock
awards and bonuses otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific cases. 
 26.
INSIDER TRADING POLICY. Each Participant who receives an Award shall comply with any policy adopted by the Company from time to time covering transactions in the Company’s securities by Employees, officers and/or directors of the
Company. 
 27. ALL AWARDS SUBJECT TO COMPANY CLAWBACK OR RECOUPMENT POLICY. All Awards, subject to applicable law, shall be subject to
clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or required by law during the term of Participant’s employment or other service with the Company that is applicable to executive officers,
employees, directors or other service providers of the Company, and in addition to any other remedies available under such policy and applicable law, may require the cancelation of outstanding Awards and the recoupment of any gains realized with
respect to Awards.

is reasonably susceptible of cure, the Participant shall be entitled to receive at least 30 days to cure the breach fully after receiving written notice from the Company; or (e) unauthorized use or disclosure by the Participant of any
proprietary information or trade secrets of the Company or any other party to whom the Participant owes an obligation of nondisclosure as a result of his or her relationship with the Company. The determination as to whether a Participant is being
terminated for Cause shall be made in good faith by the Company and shall be final and binding on the Participant. The foregoing definition does not in any way limit the Company’s ability to terminate a Participant’s employment or
consulting relationship at any time as provided in Section 20 above, and the term “Company” will be interpreted to include any Subsidiary or Parent, as appropriate. Notwithstanding the foregoing, the foregoing definition of
“Cause” may, in part or in whole, be modified or replaced in each individual employment agreement or Award Agreement with any Participant, provided that such document supersedes the definition provided in this Section 28.5.

(as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the total voting power represented by the Company’s then-outstanding voting securities;
provided, however, that for purposes of this subclause (a) the acquisition of additional securities by any one Person who is considered to own more than fifty percent (50%) of the total voting power of the securities of the Company will
not be considered a Corporate Transaction; (b) the consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets; (c) the consummation of a merger or consolidation of the Company with any
other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting

 16 

 
subclause (e), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Corporate
Transaction. For purposes of this definition, Persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the
Company. Notwithstanding the foregoing, to the extent that any amount constituting deferred compensation (as defined in Section 409A of the Code) would become payable under this Plan by reason of a Corporate Transaction, such amount shall
become payable only if the event constituting a Corporate Transaction would also qualify as a change in ownership or effective control of the Company or a change in the ownership of a substantial portion of the assets of the Company, each as defined
within the meaning of Code Section 409A, as it has been and may be amended from time to time, and any proposed or final Treasury Regulations and IRS guidance that has been promulgated or may be promulgated thereunder from time to time.

Participant’s express written consent: (a) any reduction in the Participant’s rate of base salary or the target bonus amount that Participant is eligible to receive, unless such reduction is consistent with a salary or bonus reduction
implemented by the Company for other similarly situated employees of the Company; or (b) a relocation of the Participant’s principal office with the Company of more than fifty (50) miles from its current location; provided, however,

initial existence of such condition(s), and (ii) the Company fails to remedy such condition(s) within thirty (30) days of receiving such written notice thereof; and provided, further, that in all events the termination of the
Participant’s employment with the Company shall not be treated as a termination for “Good Reason” unless such termination occurs not more than one hundred and twenty (120) days following the initial existence of the condition
claimed to constitute Good Reason . The foregoing definition does not in any way limit the Company’s ability to terminate a Participant’s employment or consulting relationship at any time as provided in Section 20 above, and the term
“Company” will be interpreted to include any Subsidiary or Parent, as appropriate. Notwithstanding the foregoing, the foregoing definition of “Good Reason” may, in part or in whole, be modified or replaced in each individual

she ceases to be employed (regardless of whether the termination is in breach of local employment laws or is later found to be invalid) and employment shall not be extended by any notice period or garden leave mandated by local law, provided

 STOCK OPTION AGREEMENT 

(GLOBAL) 

CASTLIGHT HEALTH, INC. 2014 EQUITY INCENTIVE PLAN

 You have been granted an Option by Castlight Health, Inc. (the “Company”) under the 2014 Equity Incentive
Plan (the “Plan”) to purchase Shares (the “Option”), subject to the terms and conditions of the Plan, the Notice of Stock Option Grant (the “Notice”) and this Stock Option
Agreement (the “Agreement”), including any applicable country-specific provisions in the appendix attached hereto (if any) (the “Appendix”), which constitutes part of this Agreement. 

1. Grant of Option. You have been granted an Option for the number of Shares set forth in the Notice at the exercise price per
Share set forth in the Notice (the “exercise price”). In the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Agreement, the terms and conditions of the Plan shall prevail.
If designated in the Notice as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an Incentive Stock Option under Section 422 of the Code. However, if this Option is intended to be an ISO, to the
extent that it exceeds the $100,000 rule of Code Section 422(d) it shall be treated as a Nonqualified Stock Option (“NSO”). 

2. Termination Period. 

(a) General Rule. If your Service terminates for any reason except death or Disability, and other than for Cause, then
this Option will expire at the close of business at Company headquarters on the date three months after your termination date. If your Service is terminated for Cause, this Option will expire upon the date of such termination. Your Service will be
considered terminated as of the date you are no longer providing services (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or the
terms of your employment agreement, if any). In case of any dispute as to whether your termination of Service has occurred, the Committee shall have sole discretion to determine whether such termination has occurred and the effective date of such
termination. The Committee shall have the exclusive discretion to determine whether you may still be considered to be providing services while on an approved leave of absence. 

(b) Death; Disability. If you die before your Service terminates, then this Option will expire at the close of business
at Company headquarters on the date 12 months after the date of death. If your Service terminates because of your Disability, then this Option will expire at the close of business at Company headquarters on the date 12 months after your termination
date. 
 (c) No Notice. You are responsible for keeping track of these exercise periods following your termination of
Service for any reason. The Company will not provide further notice of such periods. In no event shall this Option be exercised later than the Expiration Date set forth in the Notice. 

 3. Exercise of Option. 

(a) Right to Exercise. This Option is exercisable during its term in accordance with the Vesting Schedule set forth in
the Notice and the applicable provisions of the Plan and this Agreement. In the event of your death, Disability, or other cessation of Service, the exercisability of the Option is governed by the applicable provisions of the Plan, the Notice and
this Agreement. This Option may not be exercised for a fraction of a Share. 
 (b) Method of Exercise. This Option is
exercisable by delivery of an exercise notice in a form specified by the Company (the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares in respect of which the Option is being
exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan. The Exercise Notice shall be delivered in person, by mail, via
electronic mail or facsimile or by other authorized method to the Secretary of the Company or other person designated by the Company. The Exercise Notice shall be accompanied by payment of the aggregate exercise price as to all Exercised Shares.
This Option shall be deemed to be exercised upon receipt by the Company of a fully executed Exercise Notice accompanied by the aggregate exercise price and any applicable tax withholding due upon exercise of the Option. 

(c) Exercise by Another. If another person wants to exercise this Option after it has been transferred to him or her in
compliance with this Agreement, that person must prove to the Company’s satisfaction that he or she is entitled to exercise this Option. That person must also complete the proper Exercise Notice form (as described above) and pay the exercise
price (as described below) and any applicable tax withholding due upon exercise of the Option (as described below). 
 4. Method of
Payment. Payment of the aggregate exercise price shall be by any of the following, or a combination thereof, at your election: 

(a) your personal check, wire transfer, or a cashier’s check; 

(b) certificates for shares of Company stock that you own, along with any forms needed to effect a transfer of those shares to
the Company; the value of the shares, determined as of the effective date of the Option exercise, will be applied to the Option exercise price. Instead of surrendering shares of Company stock, you may attest to the ownership of those shares on a
form provided by the Company and have the same number of shares subtracted from the Option shares issued to you. However, you may not surrender, or attest to the ownership of, shares of Company stock in payment of the exercise price of your Option
if your action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to this Option for financial reporting purposes; 

(c) cashless exercise through irrevocable directions to a securities broker approved by the Company to sell all or part of the
Shares covered by this Option and to deliver to the Company from the sale proceeds an amount sufficient to pay the Option exercise price and any withholding taxes. The balance of the sale proceeds, if any, will be delivered to you. The directions
must be given by signing a special notice of exercise form provided by the Company; or 
 (d) other method authorized by the
Company. 
 5. Non-Transferability of Option. In general, except as provided below, only you may exercise this Option prior to
your death. You may not transfer or assign this Option, except as provided below. For instance, you may not sell this Option or use it as security for a loan. If you attempt to do any of these things, this Option will immediately become invalid. You
may, 

 
however, dispose of this Option in your will or in a beneficiary designation. However, if this Option is designated as a NSO in the Notice, then the Committee (as defined in the Plan) may, in its
sole discretion, allow you to transfer this Option as a gift to one or more family members. For purposes of this Agreement, “family member” means a child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former
spouse, sibling, niece, nephew, mother-in- law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law (including adoptive relationships), any individual sharing your household (other than a tenant or employee), a trust in which
one or more of these individuals have more than 50% of the beneficial interest, a foundation in which you or one or more of these persons control the management of assets, and any entity in which you or one or more of these persons own more than 50%
of the voting interest. In addition, if this Option is designated as a NSO in the Notice, then the Committee may, in its sole discretion, allow you to transfer this Option to your spouse or former spouse pursuant to a domestic relations order in
settlement of marital property rights. The Committee will allow you to transfer this Option only if both you and the transferee(s) execute the forms prescribed by the Committee, which include the consent of the transferee(s) to be bound by this
Agreement. This Option may not be transferred in any manner other than by will or by the laws of descent or distribution or court order and may be exercised during the lifetime of you only by you, your guardian, or legal representative, as permitted
in the Plan. The terms of the Plan and this Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of you. 

6. Term of Option. This Option shall in any event expire on the expiration date set forth in the Notice, which date is
10 years after the grant date (five years after the grant date if this Option is designated as an ISO in the Notice and Section 5.3 of the Plan applies). 

7. Tax Consequences. You should consult a tax advisor for tax consequences relating to this Option in the jurisdiction in which
you are subject to tax. YOU SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 
 (a)
Exercising the Option. You will not be allowed to exercise this Option unless you make arrangements acceptable to the Company to pay any withholding taxes that may be due as a result of the Option exercise. 

(b) Notice of Disqualifying Disposition of ISO Shares. If you sell or otherwise dispose of any of the Shares acquired
pursuant to an ISO on or before the later of (i) two years after the grant date, or (ii) one year after the exercise date, you shall immediately notify the Company in writing of such disposition. You agree that he or she may be subject to
income tax withholding by the Company on the compensation income recognized from such early disposition of ISO Shares by payment in cash or out of the current compensation paid to you. 

8. Withholding Taxes and Stock Withholding. Regardless of any action the Company or your actual employer (the
“Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), you acknowledge that the ultimate
liability for all Tax-Related Items legally due by you is and remains your responsibility and that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with
any aspect of the Option grant, including the grant, vesting or exercise of the Option, the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends; and (2) do not commit to structure the terms of the grant
or any aspect of the Option to reduce or eliminate your liability for Tax-Related Items. 

 Prior to exercise of the Option, you shall pay or make adequate arrangements satisfactory to the
Company and/or the Employer to satisfy all withholding and payment on account obligations of the Company and/or the Employer. In this regard, you authorize the Company and/or the Employer to withhold all applicable Tax-Related Items legally payable
by you from your wages or other cash compensation paid to you by the Company and/or the Employer. With the Company’s consent, these arrangements may also include, if permissible under local law, (a) withholding Shares that otherwise would
be issued to you when you exercise this Option, provided that the Company only withholds the amount of Shares necessary to satisfy the minimum statutory withholding amount, (b) having the Company withhold taxes from the proceeds of the sale of
the Shares, either through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf pursuant to this authorization), or (c) any other arrangement approved by the Company. The Fair Market Value of these Shares,
determined as of the effective date of the Option exercise, will be applied as a credit against the withholding taxes. Finally, you shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be
required to withhold as a result of your participation in the Plan or your purchase of Shares that cannot be satisfied by the means previously described. The Company may refuse to honor the exercise and refuse to deliver the Shares if you fail to
comply with your obligations in connection with the Tax-Related Items as described in this Section. 
 9. Acknowledgement. The
Company and you agree that the Option is granted under and governed by the Notice, this Agreement and by the provisions of the Plan (incorporated herein by reference). You: (a) acknowledge receipt of a copy of the Plan and the Plan prospectus,
(b) represent that you have carefully read and are familiar with their provisions, and (c) hereby accept the Option subject to all of the terms and conditions set forth herein and those set forth in the Plan and the Notice. You hereby
agree to accept as binding, conclusive and final all decisions or interpretations of the Committee upon any questions relating to the Plan, the Notice and the Agreement. 

10. Appendix. Notwithstanding any provisions in this Agreement, the Option grant shall be subject to any special terms and
conditions set forth in the Appendix to this Agreement for your country set forth as an attachment to this Agreement (if any). Moreover, if you relocate to one of the countries included in the Appendix, the special terms and conditions for such
country will apply to you, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this Agreement. 

11. Consent to Electronic Delivery of All Plan Documents and Disclosures. By your acceptance of this Option, you consent to the
electronic delivery of the Notice, this Agreement, the Plan, account statements, Plan prospectuses required by the Securities and Exchange Commission, U.S. financial reports of the Company, and all other documents that the Company is required to
deliver to its security holders (including, without limitation, annual reports and proxy statements) or other communications or information related to the Option. Electronic delivery 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 such other delivery determined at the Company’s discretion. You acknowledge that you may receive from the Company a paper copy of any
documents delivered electronically at no cost if 

 
you contact the Company by telephone, through a postal service or electronic mail at [insert e-mail address]. You further acknowledge that you will be provided with a paper copy of any documents
delivered electronically if electronic delivery fails; similarly, you understand that you must provide on request to the Company or any designated third party a paper copy of any documents delivered electronically if electronic delivery fails. Also,
you understand that your consent may be revoked or changed, including any change in the electronic mail address to which documents are delivered (if you have provided an electronic mail address), at any time by notifying the Company of such revised
or revoked consent by telephone, postal service or electronic mail at [insert e-mail address]. Finally, you understand that you are not required to consent to electronic delivery. To the extent you have been provided with a copy of this Agreement,
the Plan, or any other documents relating to the Option in a language other than English, the English language documents will prevail in case of any ambiguities or divergences as a result of translation. 

12. Compliance with Laws and Regulations; Legends. The issuance of Shares will be subject to and conditioned upon compliance by
the Company and you with all applicable state, federal and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s Common Stock may be listed or quoted at the
time of such issuance or transfer. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any Shares
shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the issuance of any Shares pursuant to this Option, the Company
may require you to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. The
Shares issued pursuant to this Agreement shall be endorsed with appropriate legends, if any, determined by the Company. 
 13.
Governing Law; Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a
mutually agreeable and enforceable replacement for such provision, then (a) such provision shall be excluded from this Agreement, (b) the balance of this Agreement shall be interpreted as if such provision were so excluded and (c) the
balance of this Agreement shall be enforceable in accordance with its terms. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance
with the laws of the State of Delaware, without giving effect to principles of conflicts of law. 
 14. No Rights as Employee,
Director or Consultant. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a Parent or Subsidiary of the Company, to terminate your Service, for any reason, with or without cause. 

15. Adjustment. In the event of a stock split, a stock dividend or a similar change in Company stock, the number of Shares
covered by this Option and the exercise price per Share may be adjusted pursuant to the Plan. 
 16. Lock-Up Agreement. In
connection with the initial public offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, you hereby agree not to sell, make any short

 
sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the registration) without
the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one hundred eighty (180) days) from the effective date of such registration as may be requested by the Company or such
managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering; provided however that, if during the last seventeen (17) days of the restricted period the
Company issues an earnings release or material news or a material event relating to the Company occurs, or prior to the expiration of the restricted period the Company announces that it will release earnings results during the sixteen (16)-day
period beginning on the last day of the restricted period, then, upon the request of the managing underwriter, to the extent required by any FINRA rules, the restrictions imposed by this Section shall continue to apply until the end of the third
trading day following the expiration of the fifteen (15)-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. In no event will the restricted period extend beyond two hundred sixteen
(216) days after the effective date of the registration statement. 
 17. Plan Discretionary; Extraordinary Compensation.
You acknowledge and understand that the Plan is wholly discretionary in nature. You understand that the Company has reserved the right to amend, suspend or terminate the Plan at any time, and that the grant of an Option in one year or at any time
does not in any way create any contractual or other right to receive future grants of Options or benefits in lieu of Options in any future year or in any given amount. You understand that all determinations with respect to any such future grants,
including, but not limited to, the times when Options shall be offered and the vesting schedule will be at the sole discretion of the Company. The value of the Option is an extraordinary item of compensation outside the scope of your employment
contract, if any, and is not to be considered part of your normal or expected compensation for purposes of calculating severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or
similar payments. You acknowledge that the right to be granted Options and to continue vesting or to receive further grants of Options will terminate effective as of the date upon which you receive notice of termination, regardless of when the
termination is effective. 
 18. Data Privacy. 

(a) You hereby explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of
your personal data as described in this Agreement and any other grant materials by and among, as applicable, the Employer, the Company and its Parent, and Subsidiaries for the exclusive purpose of implementing, administering and managing your
participation in the Plan (“Data”). 
 (b) You understand that the Company and the Employer may hold
certain personal information about you, including, but not limited to, your 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 Options or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in your favor, for the exclusive purpose of implementing, administering and managing the
Plan. 

 (c) You understand that Data may be transferred to a Company-designated
Plan broker or such other stock plan service provider as may be selected by the Company in the future, which is assisting the Company with the implementation, administration and management of the Plan. You understand 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 your country. You understand that you may request a list with the names and
addresses of any potential recipients of the Data by contacting your local human resources representative. You authorizes the Company, its designated Plan broker and any other possible recipients which 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 your participation in the Plan. You
understand that Data will be held only as long as is necessary to implement, administer and manage your participation in the Plan. You understand that you may, at any time, view Data, request additional information about the storage and processing
of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing your local human resources representative. Further, you understand that you are providing the consents
herein on a purely voluntary basis. If you do not consent, or if you later seek to revoke your consent, your employment status or service and career with the Employer will not be adversely affected; the only adverse consequence of refusing or
withdrawing your consent is that the Company would not be able to grant you Options or other equity awards or administer or maintain such awards. Therefore, you understand that refusing or withdrawing your consent may affect your ability to
participate in the Plan. For more information on the consequences of your refusal to consent or withdrawal of consent, you understand that you may contact your local human resources representative. 

19. Award Subject to Company Clawback or Recoupment. The Option shall be subject to clawback or recoupment pursuant
to any compensation clawback or recoupment policy adopted by the Board or required by law during the term of your employment or other service with the Company that is applicable to executive officers, employees, directors or other service providers
of the Company, and in addition to any other remedies available under such policy and applicable law may require the cancelation of your Option (whether vested or unvested) and the recoupment of any gains realized with respect to your Option. 

This Agreement and the Plan constitute the entire understanding between you and the Company regarding this Option. Any prior agreements,
commitments or negotiations concerning this Option are superseded. This Agreement may be amended only by another written agreement between the parties. 

BY ACCEPTING THIS OPTION, YOU AGREE TO ALL OF THE TERMS AND CONDITIONS DESCRIBED ABOVE AND IN THE PLAN.

the terms defined in the Plan shall have the same meanings in this Agreement. 
 1. Sale of Stock. Subject to the terms and
conditions of this Agreement, on the Purchase Date (as defined below) the Company will issue and sell to Participant, and Participant agrees to purchase from the Company the number of Shares shown on the Notice of Restricted Stock Award (the
“Notice”) at a purchase price of $             per Share. The per Share purchase price of the Shares shall be not less than the par value of the Shares as of

 2. Time and Place of Purchase. The purchase and sale of the Shares under this
Agreement shall occur at the principal office of the Company simultaneously with the execution of this Agreement by the parties, or on such other date as the Company and Participant shall agree (the “Purchase Date”). On the
Purchase Date, the Company will issue a stock certificate registered in Participant’s name, or uncertificated shares designated for the Participant in book entry form on the records of the Company’s transfer agent, representing the Shares
to be purchased by Participant against payment of the purchase price therefor by Participant by (a) check made payable to the Company, (b) cancellation of indebtedness of the Company to Participant, (c) Participant’s personal
Services that the Committee has determined to have a value not less than aggregate par value of the Shares to be issued Participant, or (d) a combination of the foregoing. 

3. Restrictions on Resale. By signing this Agreement, Participant agrees not to sell any Shares acquired pursuant to the Plan
and this Agreement at a time when applicable laws, regulations or Company or underwriter trading policies prohibit exercise or sale. This restriction will apply as long as Participant is providing Service to the Company or a Subsidiary of the
Company. 
 (a) Repurchase Right on Termination Other Than for Cause. For the purposes of this Agreement, a
“Repurchase Event” shall mean an occurrence of one of the following: 
 (i) termination of
Participant’s Service, whether voluntary or involuntary and with or without cause; 
 (ii) resignation,
retirement or death of Participant; or 

  
 1 

 (iii) any attempted transfer by Participant of the Shares, or any interest
therein, in violation of this Agreement. 
 Upon the occurrence of a Repurchase Event, the Company shall have the right (but not an obligation) to purchase
the Shares of Participant at a price equal to the Purchase Price per Share (the “Repurchase Right”). The Repurchase Right shall lapse in accordance with the vesting schedule set forth in the Notice of Restricted Stock Award.
For purposes of this Agreement, “Unvested Shares” means Stock pursuant to which the Company’s Repurchase Right has not lapsed. 

(b) Exercise of Repurchase Right. Unless the Company provides written notice to Participant within 90 days from
the date of termination of Participant’s Service to the Company that the Company does not intend to exercise its Repurchase Right with respect to some or all of the Unvested Shares, the Repurchase Right shall be deemed automatically exercised
by the Company as of the 90th day following such termination, provided that the Company may notify Participant that it is exercising its Repurchase Right as of a date prior to such 90th day. Unless Participant is otherwise notified by the Company
pursuant to the preceding sentence that the Company does not intend to exercise its Repurchase Right as to some or all of the Unvested Shares, execution of this Agreement by Participant constitutes written notice to Participant of the Company’s
intention to exercise its Repurchase Right with respect to all Unvested Shares to which such Repurchase Right applies at the time of Participant’s termination of Service. The Company, at its choice, may satisfy its payment obligation to
Participant with respect to exercise of the Repurchase Right by either (A) delivering a check to Participant in the amount of the purchase price for the Unvested Shares being repurchased, or (B) in the event Participant is indebted to the
Company, canceling an amount of such indebtedness equal to the purchase price for the Unvested Shares being repurchased, or (C) by a combination of (A) and (B) so that the combined payment and cancellation of indebtedness equals such
purchase price. In the event of any deemed automatic exercise of the Repurchase Right by canceling an amount of such indebtedness equal to the purchase price for the Unvested Shares being repurchased, such cancellation of indebtedness shall be
deemed automatically to occur as of the 90th day following termination of Participant’s Service unless the Company otherwise satisfies its payment obligations. As a result of any repurchase of Unvested Shares pursuant to the Repurchase Right,
the Company shall become the legal and beneficial owner of the Unvested Shares being repurchased and shall have all rights and interest therein or related thereto, and the Company shall have the right to transfer to its own name the number of
Unvested Shares being repurchased by the Company, without further action by Participant. 
 (c) Acceptance of
Restrictions. Acceptance of the Shares shall constitute Participant’s agreement to such restrictions and the legending of his or her certificates or the notation in the Company’s direct registration system for stock issuance and
transfer of such restrictions and accompanying legends set forth in Section 4(a) with respect thereto. Notwithstanding such restrictions, however, so long as Participant is the holder of the Shares, or any portion thereof, he or she shall be
entitled to receive all dividends declared on and to vote the Shares and to all other rights of a stockholder with respect thereto. 

  
 2 

 (d) Non-Transferability of Unvested Shares. In addition to any
other limitation on transfer created by applicable securities laws or any other agreement between the Company and Participant, Participant may not transfer any Unvested Shares, or any interest therein, unless consented to in writing by a duly
authorized representative of the Company. Any purported transfer is void and of no effect, and no purported transferee thereof will be recognized as a holder of the Unvested Shares for any purpose whatsoever. Should such a transfer purport to occur,
the Company may refuse to carry out the transfer on its books, set aside the transfer, or exercise any other legal or equitable remedy. In the event the Company consents to a transfer of Unvested Shares, all transferees of Shares or any interest
therein will receive and hold such Shares or interest subject to the provisions of this Agreement, including, insofar as applicable, the Repurchase Right. In the event of any purchase by the Company hereunder where the Shares or interest are held by
a transferee, the transferee shall be obligated, if requested by the Company, to transfer the Shares or interest to the Participant for consideration equal to the amount to be paid by the Company hereunder. In the event the Repurchase Right is
deemed exercised by the Company, the Company may deem any transferee to have transferred the Shares or interest to Participant prior to their purchase by the Company, and payment of the purchase price by the Company to such transferee shall be
deemed to satisfy Participant’s obligation to pay such transferee for such Shares or interest, and also to satisfy the Company’s obligation to pay Participant for such Shares or interest. 

(e) Assignment. The Repurchase Right may be assigned by the Company in whole or in part to any persons or
organization. 
 4. Restrictive Legends and Stop Transfer Orders. 

(a) Legends. The certificate or certificates or book entry or book entries representing the Shares shall bear or
be noted by the Company’s transfer agent with the following legend (as well as any legends required by applicable state and federal corporate and securities laws): 

THE SHARES REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A
COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. 
 (b) Stop-Transfer Notices. Participant agrees
that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make
appropriate notations to the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall not
be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as the owner or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares shall have been so transferred. 

  
 3 

 5. No Rights as Employee, Director or Consultant. Nothing in this Agreement shall
affect in any manner whatsoever the right or power of the Company, or a Parent or Subsidiary of the Company, to terminate Participant’s Service, for any reason, with or without cause. 

6. Miscellaneous. 

(a) Acknowledgement. The Company and Participant agree that the Restricted Shares are granted under and governed
by the Notice, this Agreement and by the provisions of the Plan (incorporated herein by reference). Participant: (i) acknowledges receipt of a copy of the Plan and the Plan prospectus, (ii) represents that Participant has carefully read
and is familiar with their provisions, and (iii) hereby accepts the Restricted Shares subject to all of the terms and conditions set forth herein and those set forth in the Plan and the Notice. 

(b) Entire Agreement; Enforcement of Rights. This Agreement, the Plan and the Notice constitute the entire
agreement and understanding of the parties relating to the subject matter herein and supersede all prior discussions between them. Any prior agreements, commitments or negotiations concerning the purchase of the Shares hereunder are superseded. No
modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing and signed by the parties to this Agreement. The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party. 
 (c) Compliance with Laws and
Regulations. The issuance of Shares will be subject to and conditioned upon compliance by the Company and Participant with all applicable state and federal laws and regulations and with all applicable requirements of any stock exchange or
automated quotation system on which the Company’s Common Stock may be listed or quoted at the time of such issuance or transfer. 

(d) Governing Law; Severability. If one or more provisions of this Agreement are held to be unenforceable under
applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this
Agreement, (ii) the balance of this Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of this Agreement shall be enforceable in accordance with its terms. This Agreement and all acts and
transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law. 

(e) Construction. This Agreement is the result of negotiations between and has been reviewed by each of the
parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 

(f) Notices. Any notice to be given under the terms of the Plan shall be addressed to the Company in care of its
principal office, and any notice to be given to the Participant shall be addressed to such Participant at the address maintained by the Company for such person or at such other address as the Participant may specify in writing to the Company. 

  
 4 

 (g) Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall he deemed an original and all of which together shall constitute one instrument. 
 (h)
U.S. Tax Consequences. Unless an Election (defined below) is made, in which case, the tax mechanics under Section 8 apply, upon vesting of Shares, Participant will include in taxable income the difference between the fair market
value of the vesting Shares, as determined on the date of their vesting, and the price paid for the Shares. This will be treated as ordinary income by Participant and will be subject to withholding by the Company when required by applicable law. In
the absence of an Election, the Company shall withhold a number of vesting Shares with a fair market value (determined on the date of their vesting) equal to the minimum amount the Company is required to withhold for income and employment taxes. If
Participant makes an Election, then Participant must, prior to making the Election, pay in cash (or check) to the Company an amount equal to the amount the Company is required to withhold for income and employment taxes. 

7. Withholding Taxes. Regardless of any action the Company or your employer (the “Employer”) takes with
respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items legally due by
you is and remains your responsibility and that the Company and/or your Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the shares received under this award,
including the award or vesting of such shares, the subsequent sale of shares under this award and the receipt of any dividends; and (2) do not commit to structure the terms of the award to reduce or eliminate your liability for Tax-Related
Items. 
 No stock certificates will be released to you unless you have paid or made adequate arrangements satisfactory to the Company and/or the Employer
to satisfy all withholding and payment on account obligations of the Company and/or your Employer. In this regard, you authorize the Company and/or your Employer to withhold all applicable Tax-Related Items legally payable by you from your wages or
other cash compensation paid to you by the Company and/or your Employer. With the Company’s consent, these arrangements may also include, if permissible under local law, (a) withholding shares that otherwise would be delivered to you when
they vest having a Fair Market Value equal to the amount necessary to satisfy the minimum statutory withholding amount, (b) having the Company withhold taxes from the proceeds of the sale of the Shares, either through a voluntary sale or
through a mandatory sale arranged by the Company (on your behalf pursuant to this authorization), or (c) any other arrangement approved by the Company. The Fair Market Value of these shares, determined as of the date when taxes otherwise would
have been withheld in cash, will be applied as a credit against the withholding taxes. Finally, you shall pay to the Company or your Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of
your participation in the Plan or your acquisition of shares that cannot be satisfied by the means previously described. The Company may refuse to deliver the shares if you fail to comply with your obligations in connection with the Tax-Related
Items as described in this section.

 8. Section 83(b) Election. Participant hereby acknowledges that he or she has
been informed that, with respect to the purchase of the Shares, an election may be filed by the Participant with the Internal Revenue Service, within 30 days of the purchase of the Shares, electing pursuant to Section 83(b) of the Code to be
taxed currently on any difference between the purchase price of the Shares and their Fair Market Value on the date of purchase (the “Election”). Making the Election will result in recognition of taxable income to the
Participant on the date of purchase, measured by the excess, if any, of the Fair Market Value of the Shares over the purchase price for the Shares. Absent such an Election, taxable income will be measured and recognized by Participant at the time or
times on which the Company’s Repurchase Right lapses. Participant is strongly encouraged to seek the advice of his or her own tax consultants in connection with the purchase of the Shares and the advisability of filing of the Election.
PARTICIPANT ACKNOWLEDGES THAT IT IS SOLELY PARTICIPANT’S RESPONSIBILITY, AND NOT THE COMPANY’S RESPONSIBILITY, TO TIMELY FILE THE ELECTION UNDER SECTION 83(b) OF THE CODE, EVEN IF PARTICIPANT REQUESTS THE COMPANY, OR ITS
REPRESENTATIVE, TO MAKE THIS FILING ON PARTICIPANT’S BEHALF 
 9. Consent to Electronic Delivery of All Plan Documents and
Disclosures. By acceptance of these Restricted Shares, you consent to the electronic delivery of the Notice, this Restricted Stock Agreement, the Plan, account statements, Plan prospectuses required by the Securities and Exchange Commission,
U.S. financial reports of the Company, and all other documents that the Company is required to deliver to its security holders (including, without limitation, annual reports and proxy statements) or other communications or information related to the
Restricted Shares. Electronic delivery 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 such other delivery determined at
the Company’s discretion. You acknowledge that you may receive from the Company a paper copy of any documents delivered electronically at no cost if you contact the Company by telephone, through a postal service or electronic mail at [email
address]. You further acknowledge that you will be provided with a paper copy of any documents delivered electronically if electronic delivery fails; similarly, you understand that you must provide on request to the Company or any designated third
party a paper copy of any documents delivered electronically if electronic delivery fails. Also, you understand that your consent may be revoked or changed, including any change in the electronic mail address to which documents are delivered (if you
have provided an electronic mail address), at any time by notifying the Company of such revised or revoked consent by telephone, postal service or electronic mail at [email address]. Finally, you understand that you are not required to consent to
electronic delivery. To the extent you have been provided with a copy of this Agreement, the Plan, or any other documents relating to the Restricted Shares in a language other than English, the English language documents will prevail in case of any
ambiguities or divergences as a result of translation. 
 10. Lock-Up Agreement. In connection with the initial public
offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, you hereby agree not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such

  
 6 

 
period of time (not to exceed one hundred eighty (180) days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an
agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering; provided however that, if during the last seventeen (17) days of the restricted period the Company issues an earnings release or
material news or a material event relating to the Company occurs, or prior to the expiration of the restricted period the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the
restricted period, then, upon the request of the managing underwriter, to the extent required by any FINRA rules, the restrictions imposed by this Section shall continue to apply until the end of the third trading day following the expiration of the
fifteen (15)-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. In no event will the restricted period extend beyond two hundred sixteen (216) days after the effective date of
the registration statement. 
 11. Award Subject to Company Clawback or Recoupment. The Shares shall be subject to
clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or required by law during the term of your employment or other service with the Company that is applicable to executive officers, employees,
directors or other service providers of the Company, and in addition to any other remedies available under such policy and applicable law may require the cancelation of your Shares (whether vested or unvested) and the recoupment of any gains
realized with respect to your Shares. 
 BY ACCEPTING THIS AWARD OF RESTRICTED SHARES, PARTICIPANT AGREES TO ALL OF THE TERMS AND CONDITIONS DESCRIBED
ABOVE AND IN THE PLAN.

 STOCK APPRECIATION RIGHT AGREEMENT

 CASTLIGHT HEALTH, INC. 2014 EQUITY INCENTIVE
PLAN 
 You have been granted Stock Appreciation Rights (each, a “SAR”) by Castlight Health, Inc.
(the “Company”) under the Company’s 2014 Equity Incentive Plan (the “Plan”), subject to the terms and conditions of the Plan, the Notice of Stock Appreciation Right Grant (the
“Notice”) and this Stock Appreciation Right Agreement (the “Agreement”). 
 1. Grant
of SAR. You have been granted a SAR for the number of Shares set forth in the Notice. In the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Agreement, the terms and conditions of the
Plan shall prevail. 
 2. Termination Period. 

(a) General Rule. If your Service terminates for any reason except death or Disability, and other than for Cause, then
this SAR will expire at the close of business at Company headquarters on the date three months after your termination date. If your Service is terminated for Cause, this SAR will expire upon the date of such termination. Your Service will be
considered terminated as of the date you are no longer providing services (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where you are employed or the
terms of your employment agreement, if any). In case of any dispute as to whether your termination of Service has occurred, the Committee shall have sole discretion to determine whether such termination has occurred and the effective date of such
termination. The Committee shall have the exclusive discretion to determine whether you may still be considered to be providing services while on an approved leave of absence. 

(b) Death; Disability. If you die before your Service terminates, then this SAR will expire at the close of business at
Company headquarters on the date 12 months after the date of death. If your Service terminates because of your Disability, then this SAR will expire at the close of business at Company headquarters on the date 12 months after your termination date.

 (c) No Notice. You are responsible for keeping track of these exercise periods following your termination of
Service for any reason. The Company will not provide further notice of such periods. In no event shall this SAR be exercised later than the Expiration Date set forth in the Notice. 

3. Exercise of SAR. 

(a) Right to Exercise. This SAR is exercisable during its term in accordance with the Vesting Schedule set forth in the
Notice and the applicable provisions of the Plan and this Agreement. In the event of your death, Disability, or other cessation of Service, the exercisability of the SAR is governed by the applicable provisions of the Plan, the Notice and this
Agreement. This SAR may not be exercised for a fraction of a Share. 
 (b) Method of Exercise. This SAR is
exercisable by delivery of an exercise notice in a form specified by the Company (the “Exercise Notice”), which shall state the election to exercise the SAR, the number of Shares in respect of which the SAR is being exercised
(the “Exercised Shares”), and such other representations and agreements as may be required by the 

 
Company pursuant to the provisions of the Plan. The Exercise Notice shall be delivered in person, by mail, via electronic mail or facsimile or by other authorized method to the Secretary of the
Company or other person designated by the Company. This SAR shall be deemed to be exercised upon receipt by the Company of a fully executed Exercise Notice accompanied by any applicable tax withholding due upon exercise of the SAR. 

(c) Exercise by Another. If another person wants to exercise this SAR after it has been transferred to him or her in
compliance with this Agreement, that person must prove to the Company’s satisfaction that he or she is entitled to exercise this SAR. That person must also complete the proper Exercise Notice form (as described above) and pay any applicable tax
withholding due upon exercise of the SAR (as described below). 
 4. Non-Transferability of SAR. In general, except as provided
below, only you may exercise this SAR prior to your death. You may not transfer or assign this SAR, except as provided below. For instance, you may not sell this SAR or use it as security for a loan. If you attempt to do any of these things, this
SAR will immediately become invalid. You may, however, dispose of this SAR in your will or in a beneficiary designation. However, the Committee (as defined in the Plan) may, in its sole discretion, allow you to transfer this SAR as a gift to one or
more family members. For purposes of this Agreement, “family member” means a child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in- law, father-in-law, son-in-law,
daughter-in-law, brother-in-law or sister-in-law (including adoptive relationships), any individual sharing your household (other than a tenant or employee), a trust in which one or more of these individuals have more than 50% of the beneficial
interest, a foundation in which you or one or more of these persons control the management of assets, and any entity in which you or one or more of these persons own more than 50% of the voting interest. The Committee may, in its sole discretion,
allow you to transfer this SAR to your spouse or former spouse pursuant to a domestic relations order in settlement of marital property rights. The Committee will allow you to transfer this SAR only if both you and the transferee(s) execute the
forms prescribed by the Committee, which include the consent of the transferee(s) to be bound by this Agreement. This SAR may not be transferred in any manner other than by will or by the laws of descent or distribution or court order and may be
exercised during the lifetime of you only by you, your guardian, or legal representative, as permitted in the Plan. The terms of the Plan and this Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of you.

 5. Term of SAR. This SAR shall in any event expire on the expiration date set forth in the Notice, which date is
10 years after the grant date. 
 6. Tax Consequences. You should consult a tax advisor for tax consequences relating to
this SAR in the jurisdiction in which you are subject to tax. YOU SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS SAR OR DISPOSING OF THE SHARES. You will not be allowed to exercise this SAR unless you make arrangements acceptable to the Company
to pay any withholding taxes that may be due as a result of the SAR exercise. 
 7. Withholding Taxes and Stock Withholding.
Regardless of any action the Company or your actual employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding
(“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that the Company and/or the Employer (1) make no

 
representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the SAR grant, including the grant, vesting or exercise of the SAR, the
subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends; and (2) do not commit to structure the terms of the grant or any aspect of the SAR to reduce or eliminate your liability for Tax-Related Items. 

Prior to exercise of the SAR, you shall pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all withholding and
payment on account obligations of the Company and/or the Employer. In this regard, you authorize the Company and/or the Employer to withhold all applicable Tax-Related Items legally payable by you from your wages or other cash compensation paid to
you by the Company and/or the Employer. With the Company’s consent, these arrangements may also include, if permissible under local law, (a) withholding Shares that otherwise would be issued to you when you exercise this SAR, provided that
the Company only withholds the amount of Shares necessary to satisfy the minimum statutory withholding amount, (b) having the Company withhold taxes from the proceeds of the sale of the Shares, either through a voluntary sale or through a
mandatory sale arranged by the Company (on your behalf pursuant to this authorization), or (c) any other arrangement approved by the Company. The Fair Market Value of these Shares, determined as of the effective date of the SAR exercise, will
be applied as a credit against the withholding taxes. Finally, you shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of your participation in the Plan or
your purchase of Shares that cannot be satisfied by the means previously described. The Company may refuse to honor the exercise and refuse to deliver the Shares if you fail to comply with your obligations in connection with the Tax-Related Items as
described in this Section. 
 8. Acknowledgement. The Company and you agree that the SAR is granted under and governed by the
Notice, this Agreement and by the provisions of the Plan (incorporated herein by reference). You: (a) acknowledge receipt of a copy of the Plan and the Plan prospectus, (b) represent that you have carefully read and are familiar with their
provisions, and (c) hereby accept the SAR subject to all of the terms and conditions set forth herein and those set forth in the Plan and the Notice. You hereby agree to accept as binding, conclusive and final all decisions or interpretations
of the Committee upon any questions relating to the Plan, the Notice and the Agreement. 
 9. Consent to Electronic Delivery of All

of the State of Delaware, without giving effect to principles of conflicts of law.

 RESTRICTED STOCK UNIT AGREEMENT

 (GLOBAL) 

CASTLIGHT HEALTH, INC. 2014 EQUITY INCENTIVE PLAN

 You have been granted Restricted Stock Units (“RSUs”) subject to the terms, restrictions and conditions of the Plan, the
Notice of Restricted Stock Unit Award (the “Notice”) and this RSU Agreement, including any applicable country-specific provisions in the appendix attached hereto (if any) (the “Appendix”) 

1. Settlement. Settlement of RSUs shall be made within 30 days following the applicable date of vesting under the vesting
schedule set forth in the Notice. Settlement of RSUs shall be in Shares. Settlement means the delivery of the Shares vested under an RSU. No fractional RSUs or rights for fractional Shares shall be created pursuant to this RSU Agreement. 

2. No Stockholder Rights. Unless and until such time as Shares are issued in settlement of vested RSUs, you shall have no
ownership of the Shares allocated to the RSUs and shall have no right dividends or to vote such Shares. 
 3. Dividend
Equivalents. Dividends, if any (whether in cash or Shares), shall not be credited to you. 
 4. No Transfer. RSUs may
not be sold, assigned, transferred, pledged, hypothecated, or otherwise disposed of in any manner other than by will or by the laws of descent or distribution or court order or unless otherwise permitted by the Committee on a case-by-case basis.

 5. Termination. If your Service terminates for for Cause or your resignation without Good Reason, all unvested RSUs shall
be forfeited to the Company forthwith, and all rights you have to such RSUs shall immediately terminate. If your Service is terminated by the Company without Cause or by you for Good Reason, all unvested RSUs shall be forfeited to the Company three
months following the termination of your Service, and all rights you have to such RSUs shall terminate three months following the termination of your Service. Notwithstanding the foregoing, vesting ceases on such date your Service terminates (unless
determined otherwise by the Committee). Your Service will be considered terminated as of the date you are no longer providing services (regardless of the reason for such termination and whether or not later found to be invalid or in breach of
employment laws in the jurisdiction where you are employed or the terms of your employment agreement, if any). In case of any dispute as to whether your termination of Service has occurred, the Committee shall have sole discretion to determine
whether such termination has occurred and the effective date of such termination. The Committee shall have the exclusive discretion to determine whether you may still be considered to be providing services while on an approved leave of absence. 

6. Tax Consequences. You acknowledge that there will be tax consequences upon settlement of the RSUs or disposition of the
Shares, if any, received in connection therewith, and you should consult a tax adviser regarding your tax obligations prior to such settlement or disposition in the jurisdiction where you are subject to tax. 

  
 1 

 7. Withholding Taxes and Stock Withholding. Regardless of any action the Company or
your actual employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, payment on account or other tax-related withholding (“Tax-Related Items”), you
acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any
Tax-Related Items in connection with any aspect of the award, including the settlement of the RSUs, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends; and (2) do not commit to structure the
terms of the award or any aspect of the RSUs to reduce or eliminate your liability for Tax-Related Items. You acknowledge that if you are subject to Tax-Related Items in more than one jurisdiction, the Company and/or the Employer may be required to
withhold or account for Tax-Related Items in more than one jurisdiction. 
 Prior to the settlement of your RSUs, you shall pay or make adequate
arrangements satisfactory to the Company and/or the Employer to satisfy all withholding and payment on account obligations of the Company and/or the Employer. In this regard, you authorize the Company and/or the Employer to withhold all applicable
Tax-Related Items legally payable by you from your wages or other cash compensation paid to you by the Company and/or the Employer. With the Company’s consent, these arrangements may also include, if permissible under local law,
(a) withholding Shares that otherwise would be issued to you when your RSUs are settled, provided that the Company only withholds the amount of Shares necessary to satisfy the minimum statutory withholding amount, (b) having the Company
withhold taxes from the proceeds of the sale of the Shares, either through a voluntary sale or through a mandatory sale arranged by the Company (on your behalf and you hereby authorize such sales by this authorization), (c) your payment of a
cash amount, or (d) any other arrangement approved by the Company; all under such rules as may be established by the Committee and in compliance with the Company’s Insider Trading Policy and 10b5-1 Trading Plan Policy, if applicable;
provided however, that if you are a Section 16 officer of the Company under the Exchange Act, then the Committee (as constituted in accordance with Rule 16b-3 under the Exchange Act) shall establish the method of withholding from alternatives
(a)-(d) above, and the Committee shall establish the method prior to the Tax-Related Items withholding event. The Fair Market Value of these Shares, determined as of the effective date when taxes otherwise would have been withheld in cash, will
be applied as a credit against the withholding taxes. You shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of your participation in the Plan or your
purchase of Shares that cannot be satisfied by the means previously described. Finally, you acknowledge that the Company has no obligation to deliver Shares to you until you have satisfied the obligations in connection with the Tax-Related Items as
described in this Section. 
 Unless determined otherwise by the Committee in advance of a Tax-Related Items withholding event, the method
of withholding for this RSU will be (a) above. 
 8. Acknowledgement. The Company and you agree that the RSUs are granted
under and governed by the Notice, this RSU Agreement and the provisions of the Plan. You: (a) acknowledge receipt of a copy of the Plan prospectus, (b) represent that you have carefully read and are familiar with their provisions, and
(c) hereby accept the RSUs subject to all of the terms and conditions set forth herein and those set forth in the Notice. 
 9.
Entire Agreement; Enforcement of Rights. This RSU Agreement, the Plan and the Notice constitute the entire agreement and understanding of the parties relating to the subject matter herein and supersede all prior discussions between them.
Any prior agreements, commitments or 

  
 2 

 
negotiations concerning the purchase of the Shares hereunder are superseded. No modification of or amendment to this RSU Agreement, nor any waiver of any rights under this RSU Agreement, shall be
effective unless in writing and signed by the parties to this RSU Agreement. The failure by either party to enforce any rights under this RSU Agreement shall not be construed as a waiver of any rights of such party. 

10. Compliance with Laws and Regulations; Legends. The issuance of Shares will be subject to and conditioned
upon compliance by the Company and you with all applicable state, federal and foreign laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s Common Stock may be
listed or quoted at the time of such issuance or transfer. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance
and sale of any Shares shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the issuance of any Shares pursuant to this
RSU, the Company may require you to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by
the Company. The Shares issued pursuant to this RSU Agreement shall be endorsed with appropriate legends, if any, determined by the Company. 

11. Governing Law; Severability. If one or more provisions of this RSU Agreement are held to be unenforceable under
applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (a) such provision shall be excluded from this
RSU Agreement, (b) the balance of this RSU Agreement shall be interpreted as if such provision were so excluded and (c) the balance of this RSU Agreement shall be enforceable in accordance with its terms. This RSU Agreement and all acts
and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law. 

12. No Rights as Employee, Director or Consultant. Nothing in this RSU Agreement shall affect in any manner whatsoever the right
or power of the Company, or a Parent or Subsidiary of the Company, to terminate your Service, for any reason, with or without cause. 

13. Appendix. Notwithstanding any provisions in this RSU Agreement, the RSU shall be subject to any special terms and conditions
set forth in the Appendix to this RSU Agreement for your country set forth as an attachment to this RSU Agreement (if any). Moreover, if you relocate to one of the countries included in the Appendix, the special terms and conditions for such country
will apply to you, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendix constitutes part of this RSU Agreement. 

14. Consent to Electronic Delivery of All Plan Documents and Disclosures. By acceptance of this RSU, you consent to the
electronic delivery of the Notice, this RSU Agreement, the Plan, account statements, Plan prospectuses required by the Securities and Exchange Commission, U.S. financial reports of the Company, and all other documents that the Company is required to
deliver to its security holders (including, without limitation, annual reports and proxy statements) or other communications or information related to the RSU. Electronic delivery 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 

  
 3 

 
delivery of the document via e-mail or such other delivery determined at the Company’s discretion. You acknowledge that you may receive from the Company a paper copy of any documents
delivered electronically at no cost if you contact the Company by telephone, through a postal service or electronic mail at [insert email]. You further acknowledge that you will be provided with a paper copy of any documents delivered electronically
if electronic delivery fails; similarly, you understand that you must provide on request to the Company or any designated third party a paper copy of any documents delivered electronically if electronic delivery fails. Also, you understand that your
consent may be revoked or changed, including any change in the electronic mail address to which documents are delivered (if you have provided an electronic mail address), at any time by notifying the Company of such revised or revoked consent by
telephone, postal service or electronic mail at [insert email]. Finally, you understand that you are not required to consent to electronic delivery. To the extent you have been provided with a copy of this RSU Agreement, the Plan, or any other
documents relating to the RSU in a language other than English, the English language documents will prevail in case of any ambiguities or divergences as a result of translation. 

15. Code Section 409A. For purposes of this RSU Agreement, a termination of employment will be determined consistent
with the rules relating to a “separation from service” as defined in Section 409A of the Internal Revenue Code and the regulations thereunder (“Section 409A”). Notwithstanding anything else provided herein, to
the extent any payments provided under this RSU Agreement in connection with your termination of employment constitute deferred compensation subject to Section 409A, and you are deemed at the time of such termination of employment to be a
“specified employee” under Section 409A, then such payment shall not be made or commence until the earlier of (a) the expiration of the six-month period measured from your separation from service from the Company or (b) the
date of your death following such a separation from service; provided, however, that such deferral shall only be effected to the extent required to avoid adverse tax treatment to you including, without limitation, the additional tax for which you
would otherwise be liable under Section 409A(a)(1)(B) in the absence of such a deferral. To the extent any payment under this RSU Agreement may be classified as a “short-term deferral” within the meaning of Section 409A, such
payment shall be deemed a short-term deferral, even if it may also qualify for an exemption from Section 409A under another provision of Section 409A. Payments pursuant to this section are intended to constitute separate payments for
purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. 
 16. Lock-Up Agreement. In connection with the
initial public offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, you hereby agree not to sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may
be, for such period of time (not to exceed one hundred eighty (180) days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may
be requested by the underwriters at the time of the public offering; provided however that, if during the last seventeen (17) days of the restricted period the Company issues an earnings release or material news or a material event relating to
the Company occurs, or prior to the expiration of the restricted period the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the restricted period, then, upon the request of the
managing underwriter, to the extent required by any FINRA rules, the restrictions imposed by this Section shall continue to apply until the end of the third trading day following the expiration of the fifteen (15)-day period beginning on the
issuance of the earnings release or the occurrence of the material news or material event. In no event will the restricted period extend beyond two hundred sixteen (216) days after the effective date of the registration statement.

 17. Award Subject to Company Clawback or Recoupment. The RSU
shall be subject to clawback or recoupment pursuant to any compensation clawback or recoupment policy adopted by the Board or required by law during the term of your employment or other service with the Company that is applicable to executive
officers, employees, directors or other service providers of the Company, and in addition to any other remedies available under such policy and applicable law may require the cancelation of your RSU (whether vested or unvested) and the recoupment of
any gains realized with respect to your RSU. 
 18. Plan Discretionary; Extraordinary Compensation. You acknowledge and
understand that the Plan is wholly discretionary in nature. You understand that the Company has reserved the right to amend, suspend or terminate the Plan at any time, and that the grant of an RSU in one year or at any time does not in any way
create any contractual or other right to receive future grants of RSUs or benefits in lieu of RSUs in any future year or in any given amount. You understand that all determinations with respect to any such future grants, including, but not limited
to, the times when RSUs shall be offered, the settlement of RSUs, and the vesting schedule will be at the sole discretion of the Company. The value of the RSU is an extraordinary item of compensation outside the scope of your employment contract, if
any, and is not to be considered part of your normal or expected compensation for purposes of calculating severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.
You acknowledge that the right to be granted RSUs, receive settlement of unvested RSUs, and to continue vesting or to receive further grants of RSUs will terminate effective as of the date upon which you receive notice of termination, regardless of
when the termination is effective. 
 19. Data Privacy. 

(a) You hereby explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of
your personal data as described in this RSU Agreement and any other grant materials by and among, as applicable, the Employer, the Company and its Parent, and Subsidiaries for the exclusive purpose of implementing, administering and managing your
participation in the Plan (“Data”). 
 (b) You understand that the Company and
the Employer may hold certain personal information about you, including, but not limited to, your 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 RSUs or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in your favor, for the exclusive purpose of implementing, administering and
managing the Plan. 
 (c) You understand that Data may be transferred to a
Company-designated Plan broker or such other stock plan service provider as may be selected by the Company in the future, which is assisting the Company with the implementation, administration and management of the Plan. You
understand 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 your country. You understand that you may request a list with the names 

  
 5 

 
and addresses of any potential recipients of the Data by contacting your local human resources representative. You authorizes the Company, its designated Plan broker
and any other possible recipients which 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 your participation in the Plan. You understand that Data will be held only as long as is necessary to implement, administer and manage your participation in the
Plan. You understand that you may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case
without cost, by contacting in writing your local human resources representative. Further, you understand that you are providing the consents herein on a purely voluntary basis. If you do not consent, or if
you later seek to revoke your consent, your employment status or service and career with the Employer will not be adversely affected; the only adverse consequence of refusing or withdrawing your consent is that the Company would not be able to grant
you RSUs, options or other equity awards or administer or maintain such awards. Therefore, you understand that refusing or withdrawing your consent may affect your ability to participate in the Plan. For
more information on the consequences of your refusal to consent or withdrawal of consent, you understand that you may contact your local human resources representative. 

BY ACCEPTING THIS RSU, YOU AGREE TO ALL OF THE TERMS AND CONDITIONS DESCRIBED ABOVE AND IN THE PLAN.

 Exhibit 10.4 

CASTLIGHT HEALTH, INC. 

2014 EMPLOYEE STOCK PURCHASE PLAN 

1. Establishment of Plan. Castlight Health, Inc. proposes to grant options to purchase shares of Common Stock to eligible employees of
the Company and its Participating Corporations pursuant to this Plan. The Company intends this Plan to qualify as an “employee stock purchase plan” under Code Section 423 (including any amendments to or replacements of such Section),
and this Plan shall be so construed. Any term not expressly defined in this Plan but defined for purposes of Code Section 423 shall have the same definition herein. However, with regard to offers of options for purchase of the Common Stock
under the Plan to employees outside the United States working for a Subsidiary or an Affiliate, the Board may offer a subplan or an option that is not intended to meet the Code Section 423 requirements, provided, if necessary under Code
Section 423, that the other terms and conditions of the Plan are met. Subject to Section 14, a total of six million (6,000,000) shares of Common Stock is reserved for issuance under this Plan. 

In addition, on each January 1 for the first nine (9) calendar years after the first Offering Date, the aggregate number of shares of Common Stock
reserved for issuance under the Plan shall be increased automatically by the lesser of (a) the number of shares of Common Stock equal to one percent (1%) of the aggregate number of outstanding shares of Class A and Class B common
stock of the Company on the immediately preceding December 31 (rounded down to the nearest whole share) or (b) such number of Shares determined by the Board; provided, however, that if prior to January 1 of a calendar year, the Board
has not either confirmed the one percent (1%) increase described in clause “(a)” of this paragraph or approved an increase of a lesser number of Shares, then the Board shall be deemed to have waived the automatic increase provided for
by this paragraph, and no such increase shall occur for such calendar year;; and, provided further, that the aggregate number of shares issued over the term of this Plan shall not exceed thirty-six million (36,000,000) shares of Common
Stock. 
 The number of shares reserved for issuance under this Plan and the maximum number of shares that may be issued under this Plan shall be subject to
adjustments effected in accordance with Section 14 of this Plan. Capitalized terms not defined elsewhere in the text are defined in Section 27. 

2. Purpose. The purpose of this Plan is to provide eligible employees of the Company and Participating Corporations with a means of
acquiring an equity interest in the Company through payroll deductions, to enhance such employees’ sense of participation in the affairs of the Company and Participating Corporations, and to provide an incentive for continued employment. 

3. Administration. The Plan will be administered by the Board or the Compensation Committee of the Board (either referred to herein as
the “Committee”). Subject to the provisions of this Plan and the limitations of Section 423 of the Code or any successor provision in the Code, all questions of interpretation or application of this Plan shall be
determined by the Committee and its decisions shall be final and binding upon all Participants. The Committee will 

  
 1 

 
have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility and decide upon any and all claims filed under the Plan. Every
finding, decision and determination made by the Committee will, to the full extent permitted by law, be final and binding upon all parties. Notwithstanding any provision to the contrary in this Plan, the Committee may adopt rules and/or procedures
relating to the operation and administration of the Plan to accommodate requirements of local law and procedures outside of the United States. The Committee will have the authority to determine the Fair Market Value of the Common Stock (which
determination shall be final, binding and conclusive for all purposes) in accordance with Section 8 below and to interpret Section 8 of the Plan in connection with circumstances that impact the Fair Market Value. Members of the Committee
shall receive no compensation for their services in connection with the administration of this Plan, other than standard fees as established from time to time by the Board for services rendered by Board members serving on the Board or its
committees. All expenses incurred in connection with the administration of this Plan shall be paid by the Company. For purposes of this Plan, the Committee may designate separate offerings under the Plan (the terms of which need not be identical) in
which eligible employees of one or more Participating Corporations will participate, even if the dates of the applicable Offering Periods of each such offering are identical. 

4. Eligibility.  

(a) Any employee of the Company or the Participating Corporations is eligible to participate in an Offering Period under this
Plan except that one or more of the following categories of employees may be excluded from coverage under the Plan by the Committee (other than where prohibited by applicable law): 

(i) employees who are not employed by the Company or a Participating Corporation prior to the beginning of such Offering Period
or prior to such other time period as specified by the Committee; 
 (ii) employees who are customarily employed for twenty
(20) hours or less per week; 
 (iii) employees who are customarily employed for five (5) months or less in a
calendar year; 
 (iv) employees who, together with any other person whose stock would be attributed to such employee
pursuant to Section 424(d) of the Code, own stock or hold options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or any of its Participating
Corporations or who, as a result of being granted an option under this Plan with respect to such Offering Period, would own stock or hold options to purchase stock possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Company or any of its Participating Corporations; and 
 (v) employees who do not meet any
other eligibility requirements that the Committee may choose to impose (within the limits permitted by the Code, if applicable); 

  
 2 

 The foregoing notwithstanding, an individual shall not be eligible if his or her participation in
the Plan is prohibited by the law of any country that has jurisdiction over him or her or if he or she is subject to a collective bargaining agreement that does not provide for participation in the Plan. 

(b) Individuals who provide services to the Company or any of its Participating Corporations as independent contractors who are
reclassified as common law employees for any reason except for federal income and employment tax purposes are not eligible to participate in an Offering Period under this Plan. 

5. Offering Dates.  

(a) While the Plan is in effect, the Committee shall determine the duration and commencement date of each Offering Period,
provided that an Offering Period shall in no event be longer than twenty-seven (27) months, except as otherwise provided by an applicable subplan. Offering Periods may be consecutive or overlapping. Each Offering Period may consist of one or
more Purchase Periods during which payroll deductions of Participants are accumulated under this Plan. While the Plan is in effect, the Committee shall determine the duration and commencement date of each Purchase Period, provided that a Purchase
Period shall in no event end later than the close of the Offering Period in which it begins. Purchase Periods shall be consecutive. 

(b) The initial Offering Period shall commence on the Effective Date, and shall end with the Purchase Date that occurs on a
date selected by the Committee approximately six (6) months after the Effective Date (but in any event not more than twenty-seven (27) months after the Effective Date). The initial Offering Period shall consist of a single Purchase Period.
Thereafter, a new six-month Offering Period shall commence on each May 1 and November 1, with each such Offering Period also consisting of a single six-month Purchase Period, except as otherwise provided by an applicable subplan. The
Committee shall have the power to change these terms as provided in Section 25 below. 
 6. Participation in this Plan. 

 (a) Any employee who is an eligible employee determined in accordance with Section 4 immediately prior to the
initial Offering Period will be automatically enrolled in the initial Offering Period under this Plan at a contribution level equal to fifteen percent (15%) of such employee’s Compensation. Notwithstanding the foregoing, an eligible
employee may elect to decrease his or her contribution rate for the initial Offering Period under the Plan by delivering an enrollment/change form to the Company and/or by affecting such decrease through an authorized third party administrator (the
“Third Party Administrator”), within thirty (30) days after the filing of an effective registration statement pursuant to Form S-8, or such shorter time as may be determined by the Committee. 

(b) With respect to Offering Periods after the initial Offering Period, an eligible employee determined in accordance with
Section 4 may elect to become a Participant by submitting an enrollment/change form, or electronic representation thereof, to the Company and/or via the Third Party Administrator’s standard process, prior to the commencement of the
Offering Period to which such agreement relates in accordance with such rules as the Committee may determine. 

  
 3 

 (c) Once an employee becomes a Participant in an Offering Period, then such
Participant will automatically participate in each subsequent Offering Period commencing immediately following the last day of such prior Offering Period at the same contribution level unless the Participant withdraws or is deemed to withdraw from
this Plan or terminates further participation in the Offering Period as set forth in Section 11 below or otherwise notifies the Company of a change in the Participant’s contribution letter by filing an additional subscription agreement or
electronic representation thereof with the Company and/or the Third Party Administrator, prior to the next Offering Period. A Participant that is automatically enrolled in a subsequent Offering Period pursuant to this section is not required to file
any additional subscription agreement in order to continue participation in this Plan. 
 7. Grant of Option on Enrollment. Becoming
a Participant with respect to an Offering Period will constitute the grant (as of the Offering Date) by the Company to such Participant of an option to purchase on the Purchase Date up to that number of shares of Common Stock determined by a
fraction, the numerator of which is the amount of the contribution level for such Participant multiplied by such Participant’s Compensation (as defined in Section 9 below) during such Purchase Period and the denominator of which
is the lower of (i) eighty-five percent (85%) of the Fair Market Value of a share of the Common Stock on the Offering Date, or (ii) eighty-five percent (85%) of the Fair Market Value of a share of the Common Stock on the
Purchase Date; provided, however, that for the Purchase Period within the initial Offering Period the numerator shall be fifteen percent (15%) of the Participant’s Compensation for such Purchase Period, or such lower
percentage as determined by the Committee prior to the Effective Date or pursuant to a Participant’s election to lower the amount as set forth in Section 6(a) above, and provided, further, that the number of shares of Common
Stock subject to any option granted pursuant to this Plan shall not exceed the lesser of (x) the maximum number of shares set by the Committee pursuant to Section 10(b) below with respect to the applicable Purchase Date, or (y) the
maximum number of shares which may be purchased pursuant to Section 10(a) below with respect to the applicable Purchase Date. 
 8.
Purchase Price. The Purchase Price in any Offering Period shall be eighty-five percent (85%) of the lesser of: 

(a) The Fair Market Value on the Offering Date; or 

(b) The Fair Market Value on the Purchase Date. 

9. Payment of Purchase Price; Payroll Deduction Changes; Share Issuances.  

(a) The Purchase Price of the shares shall be accumulated by regular payroll deductions made during each Offering Period,
unless the Committee determines that contributions may be made in another form (including payment by check at the end of a Purchase Period). The deductions are made as a percentage of the Participant’s Compensation in one percent
(1%)

  
 4 

 
increments not less than one percent (1%), nor greater than fifteen percent (15%) or such lower limit set by the Committee. “Compensation” shall mean all W-2 cash
compensation, including without limitation base salary or regular hourly wages, bonuses, incentive compensation, commissions, overtime, shift premiums, plus draws against commissions (or in foreign jurisdictions, equivalent cash compensation);
however, the Committee may at any time prior to the beginning of an Offering Period determine that for that and future Offering Periods, Compensation shall mean base salary or regular hourly wages (or in foreign jurisdictions, equivalent cash
compensation). For purposes of determining a Participant’s Compensation, any election by such Participant to reduce his or her regular cash remuneration under Sections 125 or 401(k) of the Code (or in foreign jurisdictions, equivalent salary
deductions) shall be treated as if the Participant did not make such election. Payroll deductions shall commence on the first payday following the last Purchase Date (or the first payday following the Effective Date of the Plan with respect to the
initial Offering Period) and shall continue to the end of the Offering Period unless sooner altered or terminated as provided in this Plan. Notwithstanding the foregoing, the terms of any subplan may permit matching shares without the payment of any
purchase price. 
 (b) Subject to Section 25 below and to the rules of the Committee, a Participant may make changes in
the rate of payroll deductions during an Offering Period or any Purchase Period by filing with the Company a new authorization for payroll deductions. 

(c) Subject to Section 25 below and to the rules of the Committee, a Participant may reduce his or her payroll deduction
percentage to zero during an Offering Period by filing with the Company a request for cessation of payroll deductions, and after such reduction becomes effective no further payroll deductions will be made for the duration of the Offering Period.
Payroll deductions credited to the Participant’s account prior to the effective date of the request shall be used to purchase shares of Common Stock in accordance with Section (e) below. A reduction of the payroll deduction percentage to
zero shall be treated as such Participant’s withdrawal from such Offering Period, and the Plan, effective as of the day after the next Purchase Date following the filing date of such request with the Company. 

(d) All payroll deductions made for a Participant are credited to his or her account under this Plan and are deposited with the
general funds of the Company, and the Company shall not be obligated to segregate such payroll deductions, except to the extent required to be segregated due to local legal restrictions outside the United States. No interest accrues on the payroll
deductions. All payroll deductions received or held by the Company may be used by the Company for any corporate purpose. 

(e) On each Purchase Date, so long as this Plan remains in effect and provided that the Participant has not submitted a signed
and completed withdrawal form before that date which notifies the Company and/or the Third Party Administrator that the Participant wishes to withdraw from that Offering Period under this Plan and have all payroll deductions accumulated in the
account maintained on behalf of the Participant as of that date returned to the Participant, the Company shall apply the funds then in the Participant’s account to the purchase of whole shares of Common Stock reserved under the option granted
to such Participant with respect to the Offering Period to the extent that such option is exercisable on the Purchase Date. The Purchase 

  
 5 

 
Price shall be as specified in Section 8 of this Plan. Any fractional share, as calculated under this Subsection (e), shall be rounded down to the next lower whole share, unless the
Committee determines with respect to all Participants that any fractional share shall be credited as a fractional share. Any amount remaining in a Participant’s account on a Purchase Date which is less than the amount necessary to purchase a
full share of Common Stock shall be carried forward into the next Purchase Period or Offering Period, as the case may be (except to the extent required due to local legal requirements outside the United States), as otherwise determined by the
Committee. In the event that this Plan has been oversubscribed, all funds not used to purchase shares on the Purchase Date shall be returned to the Participant, without interest (except to the extent required due to local legal requirements outside
the United States). No Common Stock shall be purchased on a Purchase Date on behalf of any employee whose participation in this Plan has terminated prior to such Purchase Date. 

(f) As promptly as practicable after the Purchase Date, the Company shall issue shares for the Participant’s benefit
representing the shares purchased upon exercise of his or her option. 
 (g) During a Participant’s lifetime, his or her
option to purchase shares hereunder is exercisable only by him or her. The Participant will have no interest or voting right in shares covered by his or her option until such option has been exercised. 

(h) To the extent required by applicable federal, state, local or foreign law, a Participant shall make arrangements
satisfactory to the Company for the satisfaction of any withholding tax obligations that arise in connection with the Plan. The Company shall not be required to issue any shares of Common Stock under the Plan until such obligations are satisfied.

 10. Limitations on Shares to be Purchased. 

(a) No Participant shall be entitled to purchase stock under any Offering Period at a rate which, when aggregated with such
Participant’s rights to purchase stock, that are also outstanding in the same calendar year(s) (whether under other Offering Periods or other employee stock purchase plans of the Company, its Parent and its Subsidiaries), exceeds $25,000 in
Fair Market Value, determined as of the Offering Date, (or such other limit as may be imposed by the Code) for each calendar year in which such Offering Period is in effect (hereinafter the “Maximum Share Amount”). The Company may
automatically suspend the payroll deductions of any Participant as necessary to enforce such limit provided that when the Company automatically resumes such payroll deductions, the Company must apply the rate in effect immediately prior to such
suspension. 
 (b) The Committee may, in its sole discretion, set a lower maximum number of shares which may be purchased by
any Participant during any Offering Period than that determined under Section 10(a) above, which shall then be the Maximum Share Amount for subsequent Offering Periods; provided, however, in no event shall a Participant be permitted to purchase
more than two thousand (2,000) Shares during any one Purchase Period, irrespective of the Maximum Share Amount set forth in (a) and (b) hereof. If a new Maximum Share Amount is set, then all Participants will be notified of such
Maximum Share Amount prior to the commencement of the next Offering Period for which it is to be effective. The Maximum Share Amount shall continue to apply with respect to all succeeding Offering Periods unless revised by the Committee as set forth
above. 

  
 6 

 (c) If the number of shares to be purchased on a Purchase Date by all
Participants exceeds the number of shares then available for issuance under this Plan, then the Company will make a pro rata allocation of the remaining shares in as uniform a manner as shall be reasonably practicable and as the Committee shall
determine to be equitable. In such event, the Company will give written notice of such reduction of the number of shares to be purchased under a Participant’s option to each Participant affected. 

(d) Any payroll deductions accumulated in a Participant’s account which are not used to purchase stock due to the
limitations in this Section 10, and not covered by Section 9(e), shall be returned to the Participant as soon as administratively practicable after the end of the applicable Purchase Period, without interest (except to the extent required
due to local legal requirements outside the United States). 
 11. Withdrawal. 

(a) Each Participant may withdraw from an Offering Period under this Plan pursuant to a method specified by the Company. Such
withdrawal may be elected at any time prior to the end of an Offering Period, or such other time period as specified by the Committee. 

(b) Upon withdrawal from this Plan, the accumulated payroll deductions shall be returned to the withdrawn Participant, without
interest, and his or her interest in this Plan shall terminate. In the event a Participant voluntarily elects to withdraw from this Plan, he or she may not resume his or her participation in this Plan during the same Offering Period, but he or she
may participate in any Offering Period under this Plan which commences on a date subsequent to such withdrawal by filing a new authorization for payroll deductions in the same manner as set forth in Section 6 above for initial participation in
this Plan. 
 12. Termination of Employment. Termination of a Participant’s employment for any reason, including retirement,
death, disability, or the failure of a Participant to remain an eligible employee of the Company or of a Participating Corporation, immediately terminates his or her participation in this Plan. In such event, accumulated payroll deductions credited
to the Participant’s account will be returned to him or her or, in the case of his or her death, to his or her legal representative, without interest (except to the extent required due to local legal requirements outside the United States). For
purposes of this Section 12, an employee will not be deemed to have terminated employment or failed to remain in the continuous employ of the Company or of a Participating Corporation in the case of sick leave, military leave, or any other
leave of absence approved by the Company; provided that such leave is for a period of not more than ninety (90) days or reemployment upon the expiration of such leave is guaranteed by contract or statute. The Company will have sole
discretion to determine whether a Participant has terminated employment and the effective date on which the Participant terminated employment, regardless of any notice period or garden leave required under local law. 

  
 7 

 13. Return of Payroll Deductions. In the event a Participant’s interest in this Plan
is terminated by withdrawal, termination of employment or otherwise, or in the event this Plan is terminated by the Board, the Company shall deliver to the Participant all accumulated payroll deductions credited to such Participant’s account.
No interest shall accrue on the payroll deductions of a Participant in this Plan (except to the extent required due to local legal requirements outside the United States). 

14. Capital Changes. If the number of outstanding Shares is changed by a stock dividend, recapitalization, stock split, reverse stock
split, subdivision, combination, reclassification or similar change in the capital structure of the Company, without consideration, then the Committee shall adjust the number and class of Common Stock that may be delivered under the Plan, the
Purchase Price and the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised, and the numerical limits of Sections 1 and 10 shall be proportionately adjusted, subject to any required action by the
Board or the stockholders of the Company and in compliance with applicable securities laws; provided that fractions of a Share will not be issued. 

15. Nonassignability. Neither payroll deductions credited to a Participant’s account nor any rights with regard to the exercise of
an option or to receive shares under this 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 22 below) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be void and without effect. 
 16. Use of Participant Funds and
Reports. The Company may use all payroll deductions received or held by it under the Plan for any corporate purpose, and the Company will not be required to segregate Participant payroll deductions (except to the extent required due to local
legal requirements outside the United States). Until Shares are issued, Participants will only have the rights of an unsecured creditor. Each Participant shall receive, or have access to, promptly after the end of each Purchase Period a report of
his or her account setting forth the total payroll deductions accumulated, the number of shares purchased, the Purchase Price thereof and the remaining cash balance, if any, carried forward or refunded, as determined by the Committee in conformance
with Section 9 of the Plan, to the next Purchase Period or Offering Period, as the case may be. 
 17. Notice of Disposition.
Each U.S. taxpayer Participant shall notify the Company in writing if the Participant disposes of any of the shares purchased in any Offering Period pursuant to this Plan if such disposition occurs within two (2) years from the Offering Date or
within one (1) year from the Purchase Date on which such shares were purchased (the “Notice Period”). The Company may, at any time during the Notice Period, place a legend or legends on any certificate representing
shares acquired pursuant to this Plan requesting the Company’s transfer agent to notify the Company of any transfer of the shares. The obligation of the Participant to provide such notice shall continue notwithstanding the placement of any such
legend on the certificates. 
 18. No Rights to Continued Employment. Neither this Plan nor the grant of any option hereunder shall
confer any right on any employee to remain in the employ of the Company or any Participating Corporation, or restrict the right of the Company or any Participating Corporation to terminate such employee’s employment. 

  
 8 

 19. Equal Rights And Privileges. All eligible employees granted an option under this Plan
that is intended to meet the Code Section 423 requirements shall have equal rights and privileges with respect to this Plan or within any separate offering under the Plan so that this Plan qualifies as an “employee stock purchase
plan” within the meaning of Section 423 or any successor provision of the Code and the related regulations. Any provision of this Plan which is inconsistent with Section 423 or any successor provision of the Code shall, without
further act or amendment by the Company or the Committee, be reformed to comply with the requirements of Section 423. This Section 19 shall take precedence over all other provisions in this Plan. 

20. Notices. All notices or other communications by a Participant to the Company under or in connection with this Plan shall be deemed
to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

21. Term; Stockholder Approval. This Plan will become effective on the Effective Date. This Plan shall be approved by the stockholders
of the Company, in any manner permitted by applicable corporate law, within twelve (12) months before or after the date this Plan is adopted by the Board. No purchase of shares that are subject to such stockholder approval before becoming
available under this Plan shall occur prior to stockholder approval of such shares and the Committee may delay any Purchase Date and postpone the commencement of any Offering Period subsequent to such Purchase Date as deemed necessary or desirable
to obtain such approval (provided that if a Purchase Date would occur more than twenty-four (24) months after commencement of the Offering Period to which it relates, then such Purchase Date shall not occur and instead such Offering Period
shall terminate without the purchase of such shares and Participants in such Offering Period shall be refunded their contributions without interest). This Plan shall continue until the earlier to occur of (a) termination of this Plan by the
Board (which termination may be effected by the Board at any time pursuant to Section 25 below), (b) issuance of all of the shares of Common Stock reserved for issuance under this Plan, or (c) the tenth anniversary of the first
Purchase Date under the Plan. 
 22. Designation of Beneficiary. 

(a) If provided in the subscription agreement, a Participant may file a written or electronic designation of a beneficiary who
is to receive any shares and cash, if any, from the Participant’s account under this Plan in the event of such Participant’s death subsequent to the end of a Purchase Period but prior to delivery to him of such shares and cash. In
addition, a Participant may file a written or electronic designation of a beneficiary who is to receive any cash from the Participant’s account under this Plan in the event of such Participant’s death prior to a Purchase Date. Such form
shall be valid only if it was filed with the Company and/or the Third Party Administrator at the prescribed location before the Participant’s death. 

  
 9 

 (b) Such designation of beneficiary may be changed by the Participant at any time
by written notice filed with the Company at the prescribed location before the Participant’s death. In the event of the death of a Participant and in the absence of a beneficiary validly designated under this Plan who is living at the time of
such Participant’s death, the Company shall deliver such 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 or cash to the spouse or, if no spouse is known to the Company, then 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. 
 23. Conditions Upon Issuance of Shares; Limitation on Sale of Shares. Shares shall not
be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the
Securities Act, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange or automated quotation system upon which the shares may then be listed, exchange control restrictions and/or securities
law restrictions outside the United States, and shall be further subject to the approval of counsel for the Company with respect to such compliance. Shares may be held in trust or subject to further restrictions as permitted by any subplan. 

24. Applicable Law. The Plan shall be governed by the substantive laws (excluding the conflict of laws rules) of the State of Delaware.

 25. Amendment or Termination. The Committee, in its sole discretion, may amend, suspend, or terminate the Plan, or any part
thereof, at any time and for any reason. If the Plan is terminated, the Committee, 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
Purchase Date (which may be sooner than originally scheduled, if determined by the Committee in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to
Section 14). If an Offering Period is terminated prior to its previously-scheduled expiration, all amounts then credited to Participants’ accounts for such Offering Period, which have not been used to purchase shares of Common Stock, shall
be returned to those Participants (without interest thereon, except as otherwise required under local laws) as soon as administratively practicable. Further, the Committee will be entitled to establish rules to change the Purchase Periods and
Offering Periods, limit the frequency and/or number of changes in the amount withheld during a Purchase Period or an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll
withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the administration of the Plan, 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 amounts withheld from the Participant’s base salary or regular hourly wages, and establish such other limitations or procedures as the
Committee determines in its sole discretion advisable which are consistent with the Plan. Such actions will not require stockholder approval or the consent of any Participants. However, no amendment shall be made without approval of the stockholders
of the Company (obtained in accordance with Section 21 above) within twelve (12) months of the adoption of such amendment (or earlier if 

  
 10 

 
required by Section 21) if such amendment would: (a) increase the number of shares that may be issued under this Plan; or (b) change the designation of the employees (or class of
employees) eligible for participation in this Plan. In addition, in the event the Committee determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Committee may, in its discretion and, to
the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequences including, but not limited to: (i) amending the definition of Compensation, including with respect to an Offering Period
underway at the time; (ii) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price; (iii) shortening any Offering Period by setting a Purchase Date, including an
Offering Period underway at the time of the Committee action; (iv) reducing the maximum percentage of compensation a participant may elect to set aside as payroll deductions; and (v) reducing the maximum number of shares of Common Stock a
Participant may purchase during any Offering Period. Such modifications or amendments will not require approval of the stockholders of the Company or the consent of any Participants. 

26. Corporate Transactions. In the event of a Corporate Transaction (as defined below), each outstanding right to purchase Common Stock
will be assumed or an equivalent option substituted by the successor corporation or a parent or a subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the purchase right, the
Offering Period with respect to which such purchase right relates will be shortened by setting a new Purchase Date (the “New Purchase Date”) and will end on the New Purchase Date. The New Purchase Date shall occur on or prior
to the consummation of the Corporate Transaction, and the Plan shall terminate on the consummation of the Corporate Transaction. 
 27.

	 SECTION 3:
 ENROLL
	  	 I hereby elect to participate in the ESPP, effective at the beginning of the next Offering Period. I elect to purchase shares of
the Common Stock of the Company subject to the terms and conditions of the ESPP and this Enrollment/Change Form (the “Enrollment/Change Form”). I understand that shares of Common Stock purchased on my behalf will be issued in street name
and deposited directly into my brokerage account with [Broker] or its affiliates. I hereby agree to take all steps, and sign all forms, required to establish an account with [Broker] or its affiliates for this purpose.

 
 My participation will continue as long as I remain eligible, unless I withdraw from the
ESPP by filing a new Enrollment/Change Form with the Company. I understand that I must notify the Company of any disposition of shares of Common Stock purchased under the ESPP.

		
	 SECTION 4:
 ELECT CONTRIBUTION
PERCENTAGE
	  	 I hereby authorize the Company to withhold from each of my paychecks __% of my Compensation (as defined in the ESPP) paid during
such Offering Period as long as I continue to participate in the ESPP or otherwise instruct the Company by filing a subsequent Enrollment/Change Form. That amount will be applied to the purchase of shares of the Company’s Common Stock pursuant
to the ESPP. The percentage must be a whole number (from 1%, up to a maximum of 15%).
  

If this is a change to my current enrollment, this represents an  ̈-increase
 ̈-decrease to my contribution percentage.
  

Note: You may not increase your contribution at any time within a Purchase Period. You may decrease your contribution percentage to a percentage other
than 0% only once within a Purchase Period to be effective during that Purchase Period. A change will become effective as soon as reasonably practicable after the form is received by the Company. An increase in your contribution percentage can
only take effect with the next Offering Period.

			
	 SECTION 5:
 DISCONTINUE
CONTRIBUTIONS
	  	  ̈       I hereby
