4. Administration of the Plan.  
 (a) Procedure.  
 (i) Multiple Administrative
Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan. 
 (ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder as “performance-based compensation” within the
meaning of Section 162(m) of the Code, the Plan shall be administered by a Committee of two or more “outside directors” within the meaning of Section 162(m) of the Code. For purposes of qualifying grants of Awards as
“performance-based compensation” under Section 162(m) of the Code, the Committee, in its discretion, may set restrictions based upon the achievement of Performance Goals. The Performance Goals shall be set by the Committee on or
before the latest date permissible to enable the Awards to qualify as “performance-based compensation” under Section 162(m) of the Code. In granting Awards which are intended to qualify under Section 162(m) of the Code, the
Committee shall follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Awards under Section 162(m) of the Code (e.g., in determining the Performance Goals). 

(iii) Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under
Rule 16b-3, the transactions contemplated hereunder shall be structured to satisfy the requirements for exemption under Rule 16b-3. 
 (iv) Other Administration. Other than as provided above, the Plan shall be administered by (A) the Board or (B) a Committee, which committee shall be constituted to satisfy
Applicable Laws. 

  
 4 








 (b) Powers of the Administrator. Subject to the provisions
of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion: 

(i) to determine the Fair Market Value; 

(ii) to select the Service Providers to whom Awards may be granted hereunder; 

(iii) to determine the number of Shares to be covered by each Award granted hereunder; 

(iv) to approve forms of agreement for use under the Plan; 

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted
hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions in
connection with the termination of a Participant’s status as a Service Provider, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator, in its sole
discretion, shall determine; 
 (vi) to construe and interpret the terms of the Plan and awards granted
pursuant to the Plan; 
 (vii) to prescribe, amend and rescind rules and regulations relating to the Plan,
including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax treatment under foreign tax laws; 
 (viii) to modify or amend each Award (subject to Section 17(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Awards longer than is
otherwise provided for in the Plan; 
 (ix) to allow Participants to satisfy withholding tax obligations by
electing to have the Company withhold from the Shares to be issued upon exercise of an Award that number of Shares having a Fair Market Value equal to the minimum amount required to be withheld. The Fair Market Value of the Shares to be withheld
shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem
necessary or advisable; 
 (x) to authorize any person to execute on behalf of the Company any instrument
required to effect the grant of an Award previously granted by the Administrator; 
 (xi) to allow a
Participant to defer the receipt of payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award; or 
 (xii) to make all other determinations deemed necessary or advisable for administering the Plan. 
 (c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations shall be final and binding on all Participants and any other holders of
Awards. 
 5. Eligibility. Nonstatutory Stock Options, Stock Purchase Rights, Stock Appreciation Rights, and
Restricted Stock Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 

6. Limitations.  
 (a) Each Option shall be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the
aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000,
such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined
as of the time the Option with respect to such Shares is granted. 

  
 5 








 (b) The following limitations shall apply to grants of Options and Stock Appreciation
Rights: 
 (i) No Service Provider shall be granted, in any Fiscal Year, Options or Stock Appreciation
Rights covering more than 1,000,000 Shares. 
 (ii) In connection with his or her initial service, a
Service Provider may be granted Options or Stock Appreciation Rights covering up to an additional 1,000,000 Shares, which shall not count against the limit set forth in subsection (i) above. 

(iii) The foregoing limitations shall be adjusted proportionately in connection with any change in the
Company’s capitalization as described in Section 14. 
 (iv) If an Option or Stock Appreciation
Right is cancelled in the same fiscal year of the Company in which it was granted (other than in connection with a transaction described in Section 14), the cancelled Option or Stock Appreciation Right will be counted against the limits set
forth in subsections (i) and (ii) above. For this purpose, if the exercise price of an Option or Stock Appreciation Right is reduced, the transaction will be treated as a cancellation of the Option or Stock Appreciation Right and the grant
of a new Option or Stock Appreciation Right. 
 (c) The exercise price of any Option or SAR outstanding or to be granted in
the future under the Plan shall not be reduced or cancelled and re-granted at a lower exercise price (including pursuant to any “6 month and 1 day” cancellation and re-grant scheme), regardless of whether or not the Shares
subject to the cancelled Options or SARs are put back into the available pool for grant. In addition, the Administrator shall not replace underwater Options or SARs with restricted stock or cash in an exchange, buy-back or other scheme. Moreover,
the Administrator shall not replace any Options or SARs with new options or stock appreciation rights having a lower exercise price or accelerated vesting schedule in an exchange, buy-back or other scheme. 

7. Term of Plan. Subject to Section 20 of the Plan, the Plan shall become effective upon its adoption by the Board.
It shall continue until August 15, 2018 unless terminated earlier under Section 17 of the Plan. 
 8. Stock
Options  
 (a) Term of Option. The term of each Option shall be stated in the Award Agreement, but in no
event shall the term of an Option be more than seven (7) years from the date of grant. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing
more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant or such shorter term
as may be provided in the Award Agreement. 
 (b) Option Exercise Price and Consideration. 

(i) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of
an Option shall be no less than 100% of the Fair Market Value per Share on the date of grant. In the case of an Incentive Stock Option granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than
ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. 

(ii) Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator shall fix
the period within which the Option may be exercised and shall determine any conditions that must be satisfied before the Option may be exercised. 
 (iii) Form of Consideration. The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive
Stock Option, the Administrator shall determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: 
 (1) cash; 
 (2) check; 

  
 6 








 (3) other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Participant for more than six months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option
shall be exercised; 
 (4) consideration received by the Company under a cashless exercise program
implemented by the Company in connection with the Plan; 
 (5) a reduction in the amount of any Company
liability to the Participant, including any liability attributable to the Participant’s participation in any Company-sponsored deferred compensation program or arrangement; 

(6) any combination of the foregoing methods of payment; or 

(7) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable
Laws. 
 (c) Exercise of Option.  

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder shall be exercisable
according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

(1) An Option shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise
(in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with any applicable withholding
taxes). Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Participant
or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no
right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall 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 14 of the Plan. 

(2) Exercising an Option in any manner shall decrease the number of Shares thereafter available, both for purposes of
the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service
Provider, other than upon the Participant’s death or Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination
(but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for three (3) months following the
Participant’s termination. If, on the date of termination, the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Participant
does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 

(iii) Disability of Participant. If a Participant ceases to be a Service Provider as a result of the
Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration
of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option shall remain exercisable for twelve (12) months following the Participant’s termination. If, on the date
of termination, the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, 

the Participant does not exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered
by such Option shall revert to the Plan. 
  

  
 7 








 (iv) Death of Participant. If a Participant dies while a
Service Provider, the Option may be exercised following the Participant’s death within such period of time as is specified in the Award Agreement (but in no event may the Option be exercised later than the expiration of the term of such Option
as set forth in the Award Agreement), by the Participant’s estate or by a person who acquires the right to exercise the Option by bequest or inheritance, but only to the extent that the Option is vested on the date of death. In the absence of a
specified time in the Award Agreement, the Option shall remain exercisable for twelve (12) months following the Participant’s termination. If, at the time of death, the Participant is not vested as to his or her entire Option, the Shares
covered by the unvested portion of the Option shall immediately revert to the Plan. The Option may be exercised by the executor or administrator of the Participant’s estate or, if none, by the person(s) entitled to exercise the Option under the
Participant’s will or the laws of descent or distribution. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 

9. Stock Purchase Rights.  
 (a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other Awards granted under the Plan and/or cash awards made outside of the
Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically, of the terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase (subject to the limits set forth in Section 3), the price to be paid, and the time within which the offeree must accept such offer. The offer shall be accepted by execution of a Restricted
Stock Purchase Agreement in the form determined by the Administrator. The following limitations shall apply to grants of Stock Purchase Rights: 
 (i) No Service Provider shall be granted, in any Fiscal Year, Stock Purchase Rights covering more than 750,000 Shares. 

(ii) The foregoing limitation shall be adjusted proportionately in connection with any change in the Company’s
capitalization as described in Section 14. 
 (iii) If a Stock Purchase Right is cancelled in the same
fiscal year of the Company in which it was granted (other than in connection with a transaction described in Section 14), the cancelled Stock Purchase Right will be counted against the limit set forth in subsection (i) above. 

(b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall
grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or Disability). The purchase price for Shares repurchased pursuant to
the Restricted Stock Purchase Agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at a rate determined by the
Administrator. 
 (c) Other Provisions. The Restricted Stock Purchase Agreement shall contain such other terms,
provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 

(d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent
to those of a stockholder, and shall be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is
prior to the date the Stock Purchase Right is exercised, except as provided in Section 14 of the Plan. 
 10. Stock
Appreciation Rights  
 (a) Grant of SARs. Subject to the terms and conditions of the Plan, a SAR may be
granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. The Administrator may grant Affiliated SARs, Freestanding SARs, Tandem SARs, or any combination thereof. 

  
 8 








 (b) Number of Shares. The Administrator will have complete discretion to
determine the number of SARs granted to any Service Provider. 
 (c) Exercise Price and Other Terms. The
Administrator, subject to the provisions of the Plan, will determine the terms and conditions of SARs granted under the Plan; provided, that, the exercise price of a SAR is at least 100% of the Fair Market Value of the Shares subject to the SAR;
provided, further, the exercise price of Tandem or Affiliated SARs will equal the exercise price of the related Option. 

(d) Exercise of Tandem SARs. Tandem SARs may be exercised for all or part of the Shares subject to the related Option
upon the surrender of the right to exercise the equivalent portion of the related Option. A Tandem SAR may be exercised only with respect to the Shares for which its related Option is then exercisable. With respect to a Tandem SAR granted in
connection with an Incentive Stock Option: (i) the Tandem SAR will expire no later than the expiration of the underlying Incentive Stock Option; (ii) the value of the payout with respect to the Tandem SAR will be for no more than one
hundred percent (100%) of the difference between the exercise price of the underlying Incentive Stock Option and the Fair Market Value of the Shares subject to the underlying Incentive Stock Option at the time the Tandem SAR is exercised; and
(iii) the Tandem SAR will be exercisable only when the Fair Market Value of the Shares subject to the Incentive Stock Option exceeds the Exercise Price of the Incentive Stock Option. 

(e) Exercise of Affiliated SARs. An Affiliated SAR will be deemed to be exercised upon the exercise of the related
Option. The deemed exercise of an Affiliated SAR will not necessitate a reduction in the number of Shares subject to the related Option. 
 (f) Exercise of Freestanding SARs. Freestanding SARs will be exercisable on such terms and conditions as the Administrator, in its sole discretion, will determine. 

(g) SAR Agreement. Each SAR grant will be evidenced by an Award Agreement that will specify the exercise price, the term
of the SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 
 (h) Expiration of SARs. An SAR granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award Agreement.
Notwithstanding the foregoing, the rules of Section 8(c) also will apply to SARs. 
 (i) Payment of SAR
Amount. Upon exercise of a SAR, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times 

(ii) The number of Shares with respect to which the SAR is exercised. 

At the discretion of the Administrator, the payment upon SAR exercise may be in cash, in Shares of equivalent value, or in some
combination thereof. 
 11. Restricted Stock Units.  

(a) Grant of Restricted Stock Units. Restricted Stock Units may be granted to Service Providers at any time and from time
to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in determining the number of Restricted Stock Units granted to each Participant, subject to the limits set forth in
Section 3 of the Plan. The following limitations shall apply to grants of Restricted Stock Units: 

(i) No Service Provider shall be granted, in any Fiscal Year, Restricted Stock Units covering more than
750,000 Shares.

any change in the Company’s capitalization as described in Section 14. 

  
 9 








 (iii) If a Restricted Stock Unit is cancelled in the same fiscal year
of the Company in which it was granted (other than in connection with a transaction described in Section 14), the cancelled Restricted Stock Unit will be counted against the limit set forth in subsection (i) above. 

(b) Value of Restricted Stock Units. Each Restricted Stock Unit will have an initial value that is established by the
Administrator on or before the date of grant. 
 (c) Performance Objectives and Other Terms. The Administrator
will set performance objectives or other vesting provisions (including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of
Restricted Stock Units that will be paid out to the Service Providers. The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each award of Restricted Stock
Units will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. The Administrator may set performance objectives based upon the
achievement of Company-wide, divisional, or individual goals, applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 

(d) Earning of Restricted Stock Units. After the applicable Performance Period has ended, the holder of Restricted Stock
Units will be entitled to receive a payout of the number of Restricted Stock Units earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives or other vesting
provisions have been achieved. After the grant of a Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such Restricted Stock Unit. 

(e) Form and Timing of Payment of Restricted Stock Units. Payment of earned Restricted Stock Units will be made as soon
as practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Restricted Stock Units in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value
of the earned Restricted Stock Units at the close of the applicable Performance Period) or in a combination thereof. 

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

12. Leaves of Absence. Unless the Administrator provides otherwise, vesting of Awards granted hereunder will be
suspended during any unpaid leave of absence. A Service Provider will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company,
its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a
leave of absence approved by the Company is not so guaranteed, then three months following the 91st day of such leave any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated
for tax purposes as a Nonstatutory Stock Option. 
 13. Non-Transferability of Awards. Unless determined
otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the
Participant, only by the Participant. If the Administrator makes an Award transferable, such Award shall contain such additional terms and conditions as the Administrator deems appropriate. 

14. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale.  

(a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number and class
of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award, and the numerical Share limits in Sections 3, 6, 9 and 11 of the Plan, shall be proportionately adjusted for any
increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Shares, or any other increase or decrease in the number of issued Shares effected without
receipt of consideration by the Company; provided, however, that 

  
 10 









 
conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Award. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the
Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for a Participant to have the right to exercise his or her Award until ten
(10) days prior to such transaction as to all of the Optioned Stock covered thereby, including Shares as to which the Award would not otherwise be exercisable. In addition, the Administrator may provide that any Company repurchase option
applicable to any Shares purchased upon exercise of an Award shall lapse as to all such Shares, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously
exercised, an Award will terminate immediately prior to the consummation of such proposed action. 
 (c) Merger or Asset
Sale. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Award shall be assumed or an equivalent option or right substituted by the
successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Award, the Participant will fully vest in and have the right to exercise all of his or
her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock will lapse, and, with respect to Restricted Stock Units, all
Performance Goals or other vesting criteria will be deemed achieved at target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right becomes fully vested and exercisable in lieu of assumption or
substitution in the event of a merger or sale of assets, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be fully vested and exercisable for a period of 15 days from
the date of such notice, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 
 For
the purposes of this paragraph, the Award shall be considered assumed if, following the merger or sale of assets, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the merger or sale of
assets, the consideration (whether stock, cash, or other securities or property) or, in the case of a Stock Appreciation Right upon the exercise of which the Administrator determines to pay cash or a Restricted Stock Unit which the Administrator can
determine to pay in cash, the fair market value of the consideration received in the merger or sale of assets by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets is not solely common stock of the successor corporation
or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, for each
Share subject to such Award (or in the case of Restricted Stock Units, the number of implied shares determined by dividing the value of the Restricted Stock Units by the per Share consideration received by holders of Common Stock in the merger or
sale of assets), to be solely common stock of the successor corporation or its Parent equal in fair market value to the per Share consideration received by holders of Common Stock in the merger or sale of assets. 

Notwithstanding anything in this Section 14(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of
one or more Performance Goals will not be considered assumed if the Company or its successor modifies any of such Performance Goals without the Participant’s consent; provided, however, a modification to such Performance Goals only to reflect
the successor corporation’s corporate structure post-merger or post-sale of assets will not be deemed to invalidate an otherwise valid Award assumption. 
 15. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service
Provider with the Company, nor will they interfere in any way with the Participant’s right or the Company’s right to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws.

 16. Date of Grant. The date of grant of an Award shall be, for all purposes, the
date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination shall be provided to each Participant within a reasonable time after the date of
such grant. 
 17. Amendment and Termination of the Plan.  

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Company shall obtain stockholder approval of any Plan amendment to the extent necessary
and desirable to comply with Applicable Law. Notwithstanding the foregoing, the Company shall also obtain stockholder approval of any Plan amendment or any exchange, buy-back or other scheme which would purport to reprice or otherwise cancel and
replace any Option or SAR as described in Section 6(c) of the Plan. 
 (c) Effect of Amendment or
Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and
signed by the Participant and the Company. Termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination.

 18. Conditions Upon Issuance of Shares.  

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Award unless the exercise of such Award
and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person
exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the
Company, such a representation is required. 
 19. Inability to Obtain Authority. The inability of the Company
to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, 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. 

20. Stockholder Approval. The Plan shall be subject to approval by the stockholders of the Company within twelve
(12) months after the date the Plan is adopted. Such stockholder approval shall be obtained in the manner and to the degree required under Applicable Laws.
