 3.    Stock
Subject to the Plan and Limitations on Cash Incentive Awards 
 (a) Stock Subject to the Plan 

(i) The maximum number of shares of Common Stock that may be covered by Incentive Awards granted under the Plan shall not exceed 2,220,000 shares of Common
Stock in the aggregate. Out of such aggregate, the maximum number of shares of Common Stock that may be covered by Options that are designated as “incentive stock options” within the meaning of Section 422 of the Code shall not exceed
2,220,000 shares of Common Stock. The maximum number of shares referred to in the preceding sentences of this Section 3(a)(i) shall in each case be subject to adjustment as provided in Section 10 and the following 

  
 4 

 provisions of this Section 3. Of the shares described, one hundred percent (100%) may be delivered in
connection with “full-value Awards,” meaning Awards other than Options, SARs, or Awards for which the Participant pays the intrinsic value either directly or in exchange for (or by foregoing) a right to receive a cash payment from the
Company equal to the intrinsic value of the Award. Shares of Common Stock issued under the Plan may be either authorized and unissued shares, treasury shares, shares purchased by the Company in the open market, or any combination of the preceding
categories as the Committee determines in its sole discretion. 
 (ii) For purposes of Section 3(a)(i), shares of Common Stock covered by Incentive
Awards shall only be counted as used to the extent they are actually issued and delivered to a Participant (or such Participant’s permitted transferees as described in the Plan) pursuant to the Plan. In addition, if shares of Common Stock are
issued subject to conditions which may result in the forfeiture, cancellation or return of such shares to the Company, any portion of the shares forfeited, cancelled or returned shall be treated as not issued pursuant to the Plan. In addition, if
shares of Common Stock owned by a Participant (or such Participant’s permitted transferees as described in the Plan) are tendered (either actually or through attestation) to the Company in payment of any obligation in connection with an
Incentive Award, the number of shares tendered shall be added to the number of shares of Common Stock that are available for delivery under the Plan. Shares of Common Stock covered by Incentive Awards granted pursuant to the Plan in connection with
the assumption, replacement, conversion or adjustment of outstanding equity-based awards in the context of a corporate acquisition or merger (within the meaning of NASDAQ Listing Rule 5635) shall not count as used under the Plan for purposes of this
Section 3. 
 (b) Individual Award Limits 

Subject to adjustment as provided in Section 10, the maximum number of shares of Common Stock that may be covered by Incentive Awards granted under the
Plan to any Covered Employee in any calendar year shall not exceed 450,000 shares. The amount payable to any Covered Employee with respect to any calendar year for all Cash Incentive Awards shall not exceed $3,500,000. For purposes of the preceding
sentences, the phrase “amount payable with respect to any calendar year” means the amount of cash, or value of other property, required to be paid based on the achievement of applicable Performance Measures during a Performance Period that
ends in such calendar year, disregarding any deferral pursuant to the terms of a Deferred Compensation Plan unless the terms of the deferral are intended to comply with the requirements for qualified performance-based compensation under
Section 162(m) of the Code. 
 4.    Administration of the Plan 

(a) The Plan shall be administered by a Committee of the Board of Directors consisting of two or more persons, each of whom, solely to the extent required by
applicable law, 

  
 5 

 qualifies as a “non-employee director” (within the meaning of
Rule 16b-3 promulgated under Section 16 of the Exchange Act), an “outside director” within the meaning of Treasury Regulation Section 1.162-27(e)(3)
and as “independent” as required by NASDAQ or any security exchange on which the Common Stock is listed. From time to time, the Board may increase or decrease the size of the Committee, add additional members to, remove members (with or
without cause) from, appoint new members in substitution therefor, and fill vacancies, however caused, in the Committee. The Committee shall, consistent with the terms of the Plan, from time to time designate those individuals who shall be granted
Incentive Awards under the Plan and the amount, type and other terms and conditions of such Incentive Awards. All of the powers and responsibilities of the Committee under the Plan may be delegated by the Committee, in writing, to any subcommittee
thereof, in which case the acts of such subcommittee shall be deemed to be acts of the Committee hereunder. The Committee may also from time to time authorize a subcommittee consisting of one or more members of the Board of Directors (including
members who are employees of the Company or one of its Subsidiaries) or employees of the Company or one of its Subsidiaries to grant Incentive Awards to persons who are not “executive officers” of the Company (within the meaning of Rule 16a-1 under the Exchange Act), subject to such restrictions and limitations as the Committee may specify and to the requirements of Section 157 of the Delaware General Corporation Law. 

(b) The Committee shall have full discretionary authority to administer the Plan, including discretionary authority to interpret and construe any and all
provisions of the Plan and any Award Agreement thereunder, and to adopt, amend and rescind from time to time such rules and regulations for the administration of the Plan, including rules and regulations related to
sub-plans established for the purpose of satisfying applicable foreign laws and/or qualifying for preferred tax treatment under applicable foreign tax laws, as the Committee may deem necessary or appropriate.
Decisions of the Committee shall be final, binding and conclusive on all parties. For the avoidance of doubt, the Committee may exercise all discretion granted to it under the Plan in a non-uniform manner
among Participants. 
 (c) The Committee may delegate the administration of the Plan to one or more officers or employees of the Company or one of its
Subsidiaries, and such administrator(s) may have the authority to execute and distribute Award Agreements, to maintain records relating to Incentive Awards, to process or oversee the issuance of Common Stock under Incentive Awards, to interpret and
administer the terms of Incentive Awards, and to take such other actions as may be necessary or appropriate for the administration of the Plan and of Incentive Awards under the Plan, provided that in no case shall any such administrator be
authorized (i) to grant Incentive Awards under the Plan (except in connection with any delegation made by the Committee pursuant to Section 4(a)), (ii) to take any action that would cause Incentive Awards intended to qualify as
Performance-Based Compensation to fail to so qualify, (iii) to take any action inconsistent with Section 409A of the Code or (iv) to take any action inconsistent with applicable provisions of the Delaware General Corporation Law. Any
action by any such administrator within the scope of its delegation shall be deemed for all purposes to have been taken by the Committee and, except as otherwise specifically provided, references in this Plan to the Committee shall include any such
administrator. The Committee and, to the extent it so provides, 

  
 6 

 any subcommittee, shall have sole authority to determine whether to review any actions and/or interpretations of
any such administrator, and if the Committee shall decide to conduct such a review, any such actions and/or interpretations of any such administrator shall be subject to approval, disapproval, or modification by the Committee. 

(d) On or after the date of grant of an Incentive Award under the Plan, the Committee may (i) accelerate the date on which any such Incentive Award
becomes vested, exercisable or transferable, as the case may be, (ii) extend the term of any such Incentive Award, including, without limitation, extending the period following a termination of a Participant’s Employment during which any
such Incentive Award may remain outstanding, (iii) waive any conditions to the vesting, exercisability or transferability, as the case may be, of any such Incentive Award or (iv) provide for the payment of dividends or dividend equivalents
with respect to any such Incentive Award; provided, that the Committee shall not have any such authority to the extent that the grant of such authority would cause any tax to become due under Section 409A of the Code. Notwithstanding
anything herein to the contrary, the Company shall not reprice any stock option (within the meaning of NASDAQ Listing Rule 5635(c) and any other formal or informal guidance issued by NASDAQ) without the approval of the shareholders of the Company.

 (e) The Company shall pay any amount payable with respect to an Incentive Award in accordance with the terms of such Incentive Award, provided
that the Committee may, in its discretion, defer the payment of amounts payable with respect to an Incentive Award subject to and in accordance with the terms of a Deferred Compensation Plan. 

(f) No member of the Committee shall be liable for any action, omission, or determination relating to the Plan, and the Company shall indemnify and hold
harmless each member of the Committee and each other director or employee of the Company to whom any duty or power relating to the administration or interpretation of the Plan has been delegated, against any cost or expense (including counsel fees)
or liability (including any sum paid in settlement of a claim with the approval of the Committee) arising out of any action, omission or determination relating to the Plan, unless, in either case, such action, omission or determination was taken or
made by such member, director or employee in bad faith and without reasonable belief that it was in the best interests of the Company. 

5.    Eligibility 
 The Persons who
shall be eligible to receive Incentive Awards pursuant to the Plan shall be those employees, consultants and directors of the Company or one of its Subsidiaries whom the Committee shall select from time to time, including officers of the Company or
one of its Subsidiaries, whether or not they are directors. Each Incentive Award granted under the Plan shall be evidenced by an Award Agreement. 

  
 7 

 6.    Options 

The Committee may from time to time grant Options on such terms as it shall determine, subject to the terms and conditions set forth in the Plan. The Award
Agreement shall clearly identify such Option as either an “incentive stock option” within the meaning of Section 422 of the Code or as a non-qualified stock option. 

(a) Exercise Price 
 The exercise price per share of
Common Stock covered by any Option shall be not less than one hundred percent (100%) of the Fair Market Value of a share of Common Stock on the date on which such Option is granted. 

(b) Term and Exercise of Options 
 (i) Each Option shall
become vested and exercisable on such date or dates, during such period and for such number of shares of Common Stock as shall be determined by the Committee on or after the date such Option is granted; provided, however that no Option
shall be exercisable after the expiration of ten (10) years from the date such Option is granted; and, provided, further, that each Option shall be subject to earlier termination, expiration or cancellation as provided in the Plan
or the Award Agreement. 
 (ii) Each Option shall be exercisable in whole or in part; provided, however that no partial exercise of a Option
shall be for an aggregate exercise price of less than $1,000. The partial exercise of an Option shall not cause the expiration, termination or cancellation of the remaining portion thereof. 

(iii) An Option shall be exercised by such methods and procedures as the Committee determines from time to time, including without limitation through net
physical settlement or other method of cashless exercise. 
 (c) Special Rules for Incentive Stock Options 

(i) The aggregate Fair Market Value of shares of Common Stock with respect to which “incentive stock options” (within the meaning of Section 422
of the Code) are exercisable for the first time by a Participant during any calendar year under the Plan and any other stock option plan of the Company or any of its “subsidiaries” (within the meaning of Section 424 of the Code) shall
not exceed $100,000. Such Fair Market Value shall be determined as of the date on which each such incentive stock option is granted. In the event that the aggregate Fair Market Value of shares of Common Stock with respect to such incentive stock
options exceeds $100,000, then incentive stock options granted hereunder to such Participant shall, to the extent and in the order required by regulations promulgated under the Code (or any other authority having the force of regulations),
automatically be deemed to be non-qualified stock options, but all 

  
 8 

 other terms and provisions of such incentive stock options shall remain unchanged. In the absence of such
regulations (and authority), or in the event such regulations (or authority) require or permit a designation of the Options which shall cease to constitute incentive stock options, incentive stock options granted hereunder shall, to the extent of
such excess and in the order in which they were granted, automatically be deemed to be non-qualified stock options, but all other terms and provisions of such incentive stock options shall remain unchanged.

 (ii) Incentive stock options may only be granted to individuals who are employees of the Company or its “subsidiaries” (within the meaning of
Section 424 of the Code). No incentive stock option may be granted to an individual if, at the time of the proposed grant, such individual owns stock possessing more than ten percent of the total combined Voting Power of all classes of stock of
the Company or any of its “subsidiaries” (within the meaning of Section 424 of the Code), unless (A) the exercise price of such incentive stock option is at least one hundred and ten percent (110%) of the Fair Market Value
of a share of Common Stock at the time such incentive stock option is granted and (B) such incentive stock option is not exercisable after the expiration of five (5) years from the date such incentive stock option is granted. 

7.    Other Stock-Based Awards 
 The
Committee may from time to time grant equity-based or equity-related awards not otherwise described herein in such amounts and on such terms as it shall determine, subject to the terms and conditions set forth in the Plan. Without limiting the
generality of the preceding sentence, each such Other Stock-Based Award may (i) involve the transfer of actual shares of Common Stock to Participants, either at the time of grant or thereafter, or payment in cash or otherwise of amounts based
on the value of shares of Common Stock, (ii) be subject to performance-based and/or service-based conditions, (iii) be in the form of stock appreciation rights, phantom stock, restricted stock, restricted stock units, performance shares,
deferred share units or share-denominated performance units, (iv) be designed to comply with applicable laws, including jurisdictions other than the United States and (v) be designed to qualify as Performance-Based Compensation;
provided, that each Other Stock-Based Award shall be denominated in, or shall have a value determined by reference to, a number of shares of Common Stock that is specified at the time of the grant of such Incentive Award; and provided,
further, that the exercise price applicable to stock appreciation rights shall not be less than one hundred percent (100%) of the Fair Market Value of a share of Common Stock on the date on which such Other Stock-Based Award is granted.

  
 9 

 8.    Cash Incentive Awards 

The Committee may from time to time grant Cash Incentive Awards on such terms as it shall determine, subject to the terms and conditions set forth in the Plan.
Cash Incentive Awards may be settled in cash or in other property, including shares of Common Stock, provided that the term “Cash Incentive Award” shall exclude any Option or Other Stock-Based Award. 

9.    Performance-Based Compensation 

(a) Calculation 
 The amount payable with respect to an
Incentive Award that is intended to qualify as Performance-Based Compensation shall be determined in any manner permitted by Section 162(m) of the Code. 

(b) Discretionary Reduction 
 Unless otherwise specified
in the Award Agreement, the Committee may, in its discretion, reduce or eliminate the amount payable to any Participant with respect to the Incentive Award, based on such factors as the Committee may deem relevant, but the Committee may not increase
any such amount above the amount established in accordance with the relevant Performance Schedule. For purposes of clarity, the Committee may exercise the discretion provided for by the foregoing sentence in a
non-uniform manner among Participants. 
 (c) Performance Measures 

(i) The performance goals upon which the payment or vesting of any Incentive Award (other than Options and stock appreciation rights) that is intended to
qualify as Performance-Based Compensation depends shall (A) be objective business criteria and shall otherwise meet the requirements of Section 162(m) of the Code, including the requirement that the level or levels of performance targeted
by the Committee result in the achievement of performance goals being “substantially uncertain,” and (B) relate to one or more of the following Performance Measures: market price of Common Stock, earnings per share of Common Stock,
adjusted earnings per share of Common Stock, adjusted cash earnings per share of Common Stock, income, net income or profit (before or after taxes), economic profit, operating income, return on equity or stockholder equity, total shareholder return,

 (ii) A Performance Measure (A) may relate to the performance of the Participant, the Company,
a Subsidiary, any business group, business unit or other subdivision of the Company, or any combination of the foregoing, as the Committee deems appropriate and (B) may be expressed as an amount, as an increase or decrease over a specified
period, as a relative comparison to the performance of a group of comparator companies or a published or special index, or any other measure of the selected performance criteria, as the Committee deems appropriate. Unless otherwise determined by the
Committee during the period referred to in Section 9(d), the Committee shall retain the ability to use negative discretion to reduce the amount of an Incentive Award or to exclude any adverse impact and include the positive impact of unusual,
nonrecurring or extraordinary items or expenses; items relating to financing activities; charges for restructurings; other non-operating items; discontinued operations; items related to the disposal of a
business or segment of a business; the cumulative effect of changes in accounting treatment; items related to a change in accounting principle; items related to changes in applicable laws or business conditions; any impact of changes in foreign

Within ninety (90) days after the beginning of a Performance Period, and in any case before twenty-five (25%) of the Performance Period has elapsed,
the Committee shall establish (i) Performance Targets for such Performance Period, (ii) Target Awards for each Participant, and (iii) Performance Schedules for such Performance Period. 

(e) Committee Discretion 
 Nothing in this Plan is
intended to limit the Committee’s discretion to adopt conditions with respect to any Incentive Award that is not intended to qualify as Performance-Based Compensation that relate to performance other than the Performance Measures. Furthermore,
nothing in this Plan shall be construed to require the Committee to grant any Award intended to qualify as Performance-Based Compensation. The Committee may, subject to the terms of the Plan, amend previously granted Incentive Awards in a way that
disqualifies them as Performance-Based Compensation. 
 10.    Adjustment Upon Certain Changes 

Subject to any action by the shareholders of the Company required by law, applicable tax rules or the rules of any exchange on which shares of common stock of
the Company are listed for trading: 
 (a) Shares Available for Grants 

In the event of any change in the number of shares of Common Stock outstanding by reason of any stock dividend or split, recapitalization, merger,
consolidation, combination or exchange of shares or similar corporate change, the maximum aggregate number of shares of Common Stock with respect to which the Committee may grant Incentive Awards and the maximum aggregate number of shares of Common
Stock with respect to which the Committee may grant Incentive Awards to any individual Participant in any year shall be appropriately adjusted or substituted by the Committee. In the event of any change in the number of shares of common stock of the
Company outstanding by reason of any other event or transaction, the Committee shall, to the extent deemed appropriate by the Committee, make such adjustments to the type or number of shares of Common Stock with respect to which Incentive Awards may
be granted. 

  
 12 

 (b) Increase or Decrease in Issued Shares Without Consideration 

In the event of any increase or decrease in the number of issued shares of Common Stock resulting from a subdivision or consolidation of shares of Common
Stock or the payment of a stock dividend (but only on the shares of Common Stock), or any other increase or decrease in the number of such shares effected without receipt or payment of consideration by the Company, the Committee shall, to the extent
deemed appropriate by the Committee, adjust the type or number of shares of Common Stock subject to each outstanding Incentive Award and the exercise price per share of Common Stock of each such Incentive Award. 

(c) Certain Mergers and Other Transactions 
 (i) In the
event of any merger, consolidation or similar transaction as a result of which the holders of shares of Common Stock receive consideration consisting exclusively of securities of the surviving corporation in such transaction, the Committee shall, to
the extent deemed appropriate by the Committee, adjust each Incentive Award outstanding on the date of such merger or consolidation so that it pertains and applies to the securities which a holder of the number of shares of Common Stock subject to
such Incentive Award would have received in such merger or consolidation. 
 (ii) In the event of (A) a dissolution or liquidation of the Company,
(B) a sale of all or substantially all of the Company’s assets (on a consolidated basis), (C) a merger, consolidation or similar transaction involving the Company in which the holders of shares of Common Stock receive securities
and/or other property, including cash, other than shares of the surviving corporation in such transaction, the Committee shall, to the extent deemed appropriate by the Committee, have the power to: (1) cancel, effective immediately prior to the
occurrence of such event, each Incentive Award (whether or not then exercisable or vested), and, in full consideration of such cancellation, pay to the Participant to whom such Incentive Award was granted an amount in cash, for each share of Common
Stock subject to such Incentive Award, equal to the value, as determined by the Committee, of such Incentive Award, provided that with respect to any outstanding Option such value shall be equal to the excess of (x) the value, as
determined by the Committee, of the property (including cash) received by the holder of a share of Common Stock as a result of such event over (y) the exercise price of such Option; or (2) provide for the exchange of each Incentive Award
(whether or not then exercisable or vested) for an Incentive Award with respect to (x) some or all of the property which a holder of the number of shares of Common Stock subject to such Incentive Award would have received in such transaction or
(y) securities of the acquiror or surviving entity and, incident thereto, make an equitable adjustment as determined by the Committee in the exercise price of the Incentive Award, or the number of shares or amount of property subject to the
Incentive Award or provide for a payment (in cash or other property) to the Participant to whom such Incentive Award was granted in partial consideration for the exchange of the Incentive Award. 

  
 13 

 (e) Other Changes 

In the event of any change in the capitalization of the Company or corporate change other than those specifically referred to in Sections 10(b), (c) or
(d), the Committee shall, to the extent deemed appropriate by the Committee, make such adjustments in the number and class of shares subject to Incentive Awards outstanding on the date on which such change occurs and in such other terms of such
Incentive Awards as the Committee may consider appropriate. 
 (f) Cash Incentive Awards 

In the event of any transaction or event described in this Section 10, including without limitation any corporate change referred to in paragraph
(e) hereof, the Committee shall, to the extent deemed appropriate by the Committee, make such adjustments in the terms and conditions of any Cash Incentive Award. 

(g) No Other Rights 
 Except as expressly provided in the
Plan or any Award Agreement, no Participant shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividends or dividend equivalents, any increase or decrease in the number of shares
of stock of any class or any dissolution, liquidation, merger or consolidation of the Company or any other corporation. Except as expressly provided in the Plan, 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 of shares or amount of other property subject to, or the terms related to, any Incentive Award. 

(h) Savings Clause

 (ii) With
respect to Incentive Awards which are granted to Covered Employees and are intended to qualify as Performance-Based Compensation, no provision of this Section 10 shall be given effect to the extent that such provision would cause such Incentive
Award to fail to so qualify as Performance-Based Compensation under Section 162(m) of the Code. 
 (iii) Furthermore, no provision of this
Section 10 shall be given effect to the extent such provision would result in short-swing profits liability under Section 16 of the Exchange Act or violate the exemptive conditions of Rule 16b-3 of

 11.  Change in Control; Termination of Employment 

(a) Change in Control 
 The consequences of a Change in
Control, if any, will be set forth in the Award Agreement in addition to what is provided in Section 10 hereof. 
 (b) Termination of Employment
 
 (i) Except as to any awards constituting stock rights subject to Section 409A of the Code, termination of Employment shall mean a separation
from service within the meaning of Section 409A, unless the Participant is retained as a consultant pursuant to a written agreement and such agreement provides otherwise. The Employment of a Participant with the Company shall be deemed to have
terminated for all purposes of the Plan if such person is employed by or provides services to a Person that is a Subsidiary of the Company and such Person ceases to be a Subsidiary of the Company, unless the Committee determines otherwise. A
Participant who ceases to be an employee of the Company but continues, or simultaneously commences, services as a director of the Company shall be deemed to have had a termination of Employment for purposes of the Plan. Without limiting the
generality of the foregoing, the Committee shall determine whether an authorized leave of absence, or absence in military or government service, shall constitute termination of Employment, provided that a Participant who is an employee will
not be deemed to cease employment in the case of any leave of absence approved by the Company. Furthermore, no payment shall be made with respect to any Incentive Awards under the Plan that are subject to Section 409A of the Code as a result of
any such authorized leave of absence or absence in military or government service unless such authorized leave or absence constitutes a separation from service for purposes of Section 409A of the Code and the regulations promulgated thereunder.

 (ii) The Award Agreement shall specify the consequences with respect to such Option of the termination of Employment of the Participant holding the
Option. 
 (iii) The consequences with respect to a Performance-Based Award of the termination of Employment of the Participant holding the Performance-Based
Award shall be determined by the Committee in its sole discretion and set forth in the Award Agreement, it being intended that no agreement providing for a payment to a Participant upon termination of Employment shall be given effect to the extent
that it would cause an Incentive Award that was intended to qualify as a Performance-Based Award to fail to so qualify. 
 12.  Rights Under
the Plan 
 (a) The Committee shall have full discretionary authority to administer the Plan, including discretionary authority to interpret and construe
any and all provisions of the Plan and any Award Agreement thereunder, and to adopt, amend and rescind from time to time such rules and regulations for the administration of the Plan, including rules and regulations related to 

  
 15 

 sub-plans established for the purpose of satisfying applicable foreign
laws and/or qualifying for preferred tax treatment under applicable foreign tax laws, as the Committee may deem necessary or appropriate. Decisions of the Committee shall be final, binding and conclusive on all parties. For the avoidance of doubt,
the Committee may exercise all discretion granted to it under the Plan in a non-uniform manner among Participants. 

(b) No Person shall have any rights as a stockholder with respect to any shares of Common Stock covered by or relating to any Incentive Award until the date
of the issuance of such shares on the books and records of the Company. Except as otherwise expressly provided in Section 10 hereof, no adjustment of any Incentive Award shall be made for dividends or other rights for which the record date
occurs prior to the date of such issuance. Nothing in this Section 12 is intended, or should be construed, to limit authority of the Committee to cause the Company to make payments based on the dividends that would be payable with respect to
any share of Common Stock if it were issued or outstanding, or from granting rights related to such dividends. 
 (c) The Company shall not have any
obligation to establish any separate fund or trust or other segregation of assets to provide for payments under the Plan. To the extent any person acquires any rights to receive payments hereunder from the Company, such rights shall be no greater
than those of an unsecured creditor. 
 13.  No Special Employment Rights; No Right to Incentive Award 

(a) Nothing contained in the Plan or any Award Agreement shall confer upon any Participant any right with respect to the continuation of his or her Employment
by the Company or interfere in any way with the right of the Company at any time to terminate such Employment or to increase or decrease the compensation of the Participant from the rate in existence at the time of the grant of an Incentive Award.

 (b) No person shall have any claim or right to receive an Incentive Award hereunder. The Committee’s granting of an Incentive Award to a Participant
at any time shall neither require the Committee to grant an Incentive Award to such Participant or any other Participant or other person at any time nor preclude the Committee from making subsequent grants to such Participant or any other
Participant or other person. 
 14.  Securities Matters 

(a) The Company shall be under no obligation to effect the registration pursuant to the Securities Act of any shares of Common Stock to be issued hereunder or
to effect similar compliance under any state or local laws. Notwithstanding anything herein to the contrary, the Company shall not be obligated to cause to be issued shares of Common Stock pursuant to the Plan unless and until the Company is advised
by its counsel that the issuance is in compliance with all applicable laws, regulations of governmental authority and the requirements of any securities exchange on which shares of Common Stock are traded. The Committee may require, as a condition
to the issuance of shares of Common Stock pursuant to the terms hereof, that the recipient of such shares make such covenants, agreements and representations, and that any related certificates representing such shares bear such legends, as the
Committee, in its sole discretion, deems necessary or desirable. 

  
 16 

 (b) The exercise of any Incentive Award (including, without limitation, any Option) granted hereunder shall only
be effective at such time as counsel to the Company shall have determined that the issuance and delivery of shares of Common Stock pursuant to such exercise is in compliance with all applicable laws, regulations of governmental authority and the
requirements of any securities exchange on which shares of Common Stock are traded. The Company may, in its sole discretion, defer the effectiveness of any exercise of an Incentive Award granted hereunder in order to allow the issuance of shares
pursuant thereto to be made pursuant to registration or an exemption from registration or other methods for compliance available under federal or state or local securities laws. The Company shall inform the Participant in writing of its decision to
defer the effectiveness of the exercise of an Incentive Award granted hereunder. During the period that the effectiveness of the exercise of an Incentive Award has been deferred, the Participant may, by written notice, withdraw such exercise and
obtain the refund of any amount paid with respect thereto. 
 15.  Withholding Taxes 

(a) Cash Remittance 
 Whenever withholding tax obligations
are incurred in connection with any Incentive Award, the Company shall have the right to require the Participant to remit to the Company in cash an amount sufficient to satisfy federal, state and local withholding tax requirements, if any,
attributable to such event. In addition, upon the exercise or settlement of any Incentive Award in cash, or the making of any other payment with respect to any Incentive Award (other than in shares of Common Stock), the Company shall have the right
to withhold from any payment required to be made pursuant thereto an amount sufficient to satisfy the federal, state and local withholding tax requirements, if any, attributable to such exercise, settlement or payment. 

(b) Stock Remittance 
 At the election of the
Participant, subject to the approval of the Committee, whenever withholding tax obligations are incurred in connection with any Incentive Award, the Participant may tender to the Company a number of shares of Common Stock that have been owned by the
Participant for at least six (6) months (or such other period as the Committee may determine) having a Fair Market Value at the tender date determined by the Committee to be sufficient to satisfy the minimum federal, state and local withholding
tax requirements, if any, attributable to such event. Such election shall satisfy the Participant’s obligations under Section 15(a) hereof, if any. 

(c) Stock Withholding 
 At the election of the
Participant, subject to the approval of the Committee, whenever withholding tax obligations are incurred in connection with any Incentive Award, the Company 

  
 17 

 shall withhold a number of such shares having a Fair Market Value determined by the Committee to be sufficient to
satisfy the minimum federal, state and local withholding tax requirements, if any, attributable to such event. Such election shall satisfy the Participant’s obligations under Section 15(a) hereof, if any. 

16.  Amendment or Termination of the Plan 
 The
Board of Directors may at any time suspend or discontinue the Plan or revise or amend it in any respect whatsoever; provided, however, that to the extent that any applicable law, tax requirement, or rule of a stock exchange requires
shareholder approval in order for any such revision or amendment to be effective, such revision or amendment shall not be effective without such approval. The preceding sentence shall not restrict the Committee’s ability to exercise its
discretionary authority hereunder pursuant to Section 4 hereof, which discretion may be exercised without amendment to the Plan. No provision of this Section 16 shall be given effect to the extent that such provision would cause any tax to
become due under Section 409A of the Code. Except as expressly provided in the Plan, no action hereunder may, without the consent of a Participant, adversely affect the Participant’s rights under any previously granted and outstanding
Incentive Award. Nothing herein shall cause a Performance-Based Award to cease to qualify under Section 162(m). Nothing in the Plan shall limit the right of the Company to pay compensation of any kind outside the terms of the Plan. 

17.  Recoupment 
 Notwithstanding anything in
the Plan or in any Award Agreement to the contrary, the Company will be entitled to the extent permitted or required by applicable law (including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act), Company policy
and/or the requirements of an exchange on which the Company’s shares are listed for trading, in each case, as in effect from time to time to recoup compensation of whatever kind paid or awarded by the Company at any time to a Participant under
this Plan. 
 18.  No Obligation to Exercise 

The grant to a Participant of an Incentive Award shall impose no obligation upon such Participant to exercise such Incentive Award. 

19.  Transfers 
 Incentive Awards 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 a Participant, only by the Participant; provided,
however that the Committee may permit Options that are not incentive stock options to be sold, pledged, assigned, hypothecated, transferred, or disposed of, on a general or specific basis, subject to such conditions and limitations as the
Committee may determine. Upon the death of a Participant, outstanding Incentive Awards granted to such Participant may be exercised only by the executors or administrators of the Participant’s estate or by any person or persons who shall have
acquired 

  
 18 

 such right to exercise by will or by the laws of descent and distribution. No transfer by will or the laws of
descent and distribution of any Incentive Award, or the right to exercise any Incentive Award, shall be effective to bind the Company unless the Committee shall have been furnished with (i) written notice thereof and with a copy of the will
and/or such evidence as the Committee may deem necessary to establish the validity of the transfer and (ii) an agreement by the transferee to comply with all the terms and conditions of the Incentive Award that are or would have been applicable
to the Participant and to be bound by the acknowledgements made by the Participant in connection with the grant of the Incentive Award. 

20.  Expenses and Receipts 
 The expenses of the
Plan shall be paid by the Company. Any proceeds received by the Company in connection with any Incentive Award will be used for general corporate purposes. 

21.  Failure to Comply 
 In addition to the
remedies of the Company elsewhere provided for herein, failure by a Participant to comply with any of the terms and conditions of the Plan or any Award Agreement, unless such failure is remedied by such Participant within ten days after having been
notified of such failure by the Committee, shall be grounds for the cancellation and forfeiture of such Incentive Award, in whole or in part, as the Committee, in its absolute discretion, may determine. 

22.  Governing Law 
 The Plan and the rights of
all persons under the Plan shall be construed and administered in accordance with the laws of the State of Delaware without regard to its conflict of law principles. 

23.  Severability 
 If all or any part of this
Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate any portion of this Plan not declared to be unlawful or invalid. Any Section or part of a Section so
declared to be unlawful or invalid shall, if possible, be construed in a manner that will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 

24.  Effective Date and Term of Plan 
 The
Effective Date of the Plan is             , 2013, subject to the approval of the Plan by the shareholders of the Company. No grants of Incentive Awards may be made under the Plan after

Determinations of the Committee. Any Grant, determination, prescription or other act of the Committee shall be final and conclusively binding upon all Persons. 

3.3 Indemnification of the Committee. No member of the Committee nor the Majority Unit Holder or its employees, partners, directors or
associates shall be liable for any action or determination made in good faith with respect to the Plan or any Grant. To the full extent permitted by law, the Company shall indemnify and hold harmless each Person made or threatened to be made a party
to any civil or criminal action or proceeding by reason of the fact that such Person, or such Person’s testator or intestate, is or was a member of the Committee or is or was a Majority Unit Holder or an employee, partner, director or associate
thereof, to the extent such criminal or civil action or proceeding relates to the Plan. 
 3.4 Compliance with Applicable Law; Securities Matters;
Effectiveness of Option Exercise. The Company shall be under no obligation to effect the registration pursuant to the Securities Act of any Membership Units to be issued hereunder or to effect similar compliance under any state or non-U.S. laws. Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates evidencing the Membership Units pursuant to the exercise of any Options, unless
and until the Committee has determined, with advice of counsel, that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any
exchange on which the Membership Units are listed or traded. In addition to the terms and conditions provided herein, the Committee may require that a Participant make such reasonable covenants, agreements and representations as the Committee, in
its sole discretion, deems advisable in order to comply with any such laws, regulations or requirements. The Company may, in its sole discretion, defer the effectiveness of an exercise of an Option hereunder or the issuance or transfer of the
Membership Units pursuant to any Grant pending or to ensure compliance under federal, state or non-U.S. securities laws. The Company shall inform the Participant in writing of its decision to defer the
effectiveness of the exercise of an Option or the issuance or transfer of the Membership Units pursuant to any Grant. During the period that the effectiveness of the exercise of an Option has been deferred, the Participant may, by written notice,
withdraw such exercise and obtain the refund of any amount paid with respect thereto.

 3.5 Inconsistent Terms. In the event of a conflict between the terms of the Plan, the terms of the
Management Unit Holders’ Agreement and the terms of any Unit Option Grant Agreement, the terms of the Plan shall govern except as otherwise provided herein. 

3.6 Plan Term. The Committee shall not Grant any Options under this Plan on or after the seventh anniversary of the Effective Date. All Options
which remain outstanding after such date shall continue to be governed by the Plan. 
     4.    
Options  
 Subject to adjustment as provided in Section 4.12 hereof, the Committee may grant to Participants Options to purchase up to
27,325,000 Membership Units of the Company. To the extent that any Option granted under the Plan terminates, expires or is canceled without having been exercised, the Membership Units covered by such Option shall again be available for Grant under
the Plan. 
 4.1 Exercise Price. The Exercise Price of any Option granted under the Plan shall be such price as the Board shall determine
(provided that such Exercise Price must be at least equal to the Fair Market Value of a Membership Unit on the Grant Date and must be the minimum price otherwise required by applicable law) and which shall be specified in the Unit Option Grant
Agreement. 
 4.2 Grant Date. The Grant Date of the Options shall be the date designated by the Committee and specified in the Unit Option
Grant Agreement as of the date the Option is granted. 
 4.3 Vesting Date of Options. 

4.3.1 Time-Based Option. 
 4.3.1.1 Generally.
Unless otherwise specified in a Participant’s Unit Option Grant Agreement or in an effective employment agreement, 50% of each Option granted under the Plan (the “Time-Based Option”) shall vest and become exercisable with
respect to twenty percent (20%) on each of the first five anniversaries of the Grant Date, until 100% of the Time-Based Option is fully vested and exercisable, subject in all cases to the Participant’s continued Employment through the
applicable Vesting Date. Unless the Committee provides otherwise, the vesting of the Time-Based Option may be suspended during any leave of absence as may be set forth by Company policy, if any. 

4.3.1.2 Accelerated Vesting on a Qualifying Termination. In the event that a Participant’s Employment is terminated as the result of a Qualifying
Termination, 100% of the then outstanding Time-Based Option held by the Participant shall immediately vest and become exercisable as of such Qualifying Termination of Employment. 

4.3.2 Performance-Based Option.Unless otherwise specified in a Participant’s Unit Option Grant Agreement or in an effective employment agreement,
50% of each Option granted under the Plan (the “Performance-Based Option”) shall vest and become 

  
 8 

 
exercisable only upon a Liquidity Event in which the Majority Unit Holder achieves a minimum MoM, as set forth in this Section 4.3.2, subject to the Participant’s continued Employment
with the Company up to and through the effective date of a Liquidity Event: (A) 50% of the Performance-Based Option will vest and become exercisable if the Majority Unit Holder realizes an MoM of at least 2.0 as of (and taking into account) the
Liquidity Event, and (B) 100% of the Performance-Based Option will vest and become exercisable if the Majority Unit Holder realizes an MoM of at least 3.0 as of (and taking into account) the Liquidity Event. Except as otherwise provided in a
Participant’s Unit Option Grant Agreement, following a Liquidity Event, any Performance-Based Option that has not vested and become exercisable upon such Liquidity Event shall be forfeited. Prior to any contemplated Liquidity Event, the
Committee shall make a projection using such methodologies and parameters and taking into account such factors as it, in its sole discretion, deems appropriate with respect to the expected MoM to be achieved upon such Liquidity Event, and, to the
extent the projection estimates an MoM that would result in some or all of the Performance-Based Option vesting and becoming exercisable, the Performance-Based Option shall be deemed vested to the applicable extent and solely for the purpose of
permitting the Participant to participate in such Liquidity Event with the Membership Units underlying such Performance-Based Option. 
 4.4
Expiration of Options. With respect to each Participant, such Participant’s Option(s), or portion thereof, which have not become exercisable shall expire on the date such Participant’s Employment is terminated for any reason
unless otherwise specified in the Unit Option Grant Agreement. With respect to each Participant, each Participant’s Option(s), or any portion thereof, which have become exercisable on or before the date such Participant’s Employment is
terminated (or that become exercisable as a result of such termination) shall, unless otherwise provided in the Participant’s Unit Option Grant Agreement, expire on the earliest of (i) the commencement of business on the date the
Participant’s Employment is terminated for Cause; (ii) 90 days after the date the Participant’s Employment is terminated for any reason other than Cause, death or Disability; (iii) one year after the date the Participant’s
Employment is terminated by reason of death or Disability; or (iv) the 7th anniversary of the Grant Date for such Option(s). Notwithstanding the foregoing, all Options, whether vested or unvested that have not expired sooner, shall expire on
the 7th anniversary of the Grant Date, unless otherwise provided in the Participant’s Unit Option Grant Agreement; provided, that such expiration shall occur no later than the 10th anniversary of the Grant Date. Any Option, or portion
thereof, that has become exercisable by a Permitted Transferee on account of the death of a Participant shall expire one year after the date such deceased Participant’s Employment terminated by reason of death, unless otherwise provided in the
Participant’s Unit Option Grant Agreement, and any Option or portion thereof that has been transferred to a Permitted Transferee during the lifetime of a Participant shall expire in connection with the Participant’s termination of
Employment at the time set forth under this Section 4.4 as if the Option were held directly by the Participant, unless otherwise provided in the Participant’s Unit Option Grant Agreement. Notwithstanding the foregoing, the Committee may
specify in the Unit Option Grant Agreement a different expiration date or period (not to exceed 10 years from the Grant Date) for any Option granted hereunder, and such expiration date or period shall supersede the foregoing expiration period. 

  
 9 

 4.5 Limitation on Transfer. Each Option granted to a Participant shall be exercisable only by such
Participant, except that a Participant may assign or transfer his or her rights with respect to any or all of the Options held by such Participant to: (i) such Participant’s beneficiaries or estate upon the death of the Participant (by
will, by the laws of descent and distribution or otherwise) and (ii) subject to the prior written approval by the Committee and compliance with all applicable tax, securities and other laws, any trust or custodianship created by the
Participant, the beneficiaries of which may include only the Participant, the Participant’s spouse or the Participant’s lineal descendants (by blood or adoption) (each of (i) and (ii), a “Permitted Transferee”). 

4.6 Condition Precedent to Transfer of Any Option. It shall be a condition precedent to any Transfer of any Option by any Participant that the
Transferee, shall agree prior to the Transfer in writing with the Company to be bound by the terms of the Plan, the Unit Option Grant Agreement and the Management Unit Holder’s Agreement as if he, she or it had been an original signatory
thereto, except that any provisions of the Plan based on the Employment (or termination thereof) of the original Participant shall continue to be based on the Employment (or termination thereof) of the original Participant. 

4.7 Effect of Void Transfers. In the event of any purported Transfer of any Options in violation of the provisions of the Plan, such purported
Transfer shall, to the extent permitted by applicable law, be void and of no effect. 
 4.8 Exercise of Options. A Participant (or his or her
Permitted Transferee, guardian or legal representative, if applicable) may exercise any or all of the vested Options by serving an Exercise Notice on the Company as provided in Section 4.9 hereto. 

4.9 Method of Exercise. The Option shall be exercised by delivery of written notice to the Company’s principal office (the
“Exercise Notice”), to the attention of its Secretary, no less than five business days in advance of the effective date of the proposed exercise (the “Exercise Date”). Such notice shall (a) specify the number
of Membership Units with respect to which the Option is being exercised, the Grant Date of such Option and the Exercise Date, (b) be signed by the Participant (or his or her Permitted Transferee, guardian or legal representative, if
applicable), (c) prior to the existence of a Public Market for the Membership Units of the Company, indicate in writing that the Participant agrees to be bound by the Management Unit Holders’ Agreement, and (d) if the Option is being
exercised by the Participant’s Permitted Transferee(s), such Permitted Transferee(s) shall indicate in writing that they agree to and shall be bound by the Plan and Unit Option Grant Agreement as if they had been original signatories thereto
(as provided in Section 4.6 hereof) and, prior to the existence of a Public Market for the Membership Units of the Company, by the Management Unit Holders’ Agreement. The Exercise Notice shall include payment in cash for an amount equal to
the Exercise Price multiplied by the number of Membership Units specified in such Exercise Notice or any method otherwise approved by the Committee. In addition, the Participant shall be responsible for the payment of applicable withholding and
other taxes in cash (or Membership Units if approved by the Committee) that may become due as a result of the exercise of such Option. The Committee may, in its sole discretion, permit the person exercising an Option to make the above-described
payments in forms other than cash. In addition, in the event that a Participant’s Employment terminates due to death or Disability or is terminated by the Company without Cause or by the Participant for Good Reason, the Company will permit such
Participant (or his or her Permitted Transferee, guardian or legal representative, if applicable) to exercise all or any portion of his or 

  
 10 

 her then-exercisable Option through cashless exercise (to satisfy both the exercise price and any applicable
withholding taxes), but only to the extent such right or the utilization of such right would not cause the Option to be subject to Section 409A of the Code and to the extent the Committee, in its good faith judgment, determines that exercise
through cashless exercise is permitted by, and will not result in any default under, any agreement to which the Company or its Affiliates is a party and that the Company and its Affiliates have sufficient liquidity. The partial exercise of the
Option, alone, shall not cause the expiration, termination or cancellation of the remaining Options. 
 4.10 Management Unit Holders’
Agreement. Subject to Section 3.4 herein, upon the exercise of the Options in accordance with Section 4. 9 and, prior to the existence of a Public Market, no Membership Units shall be issued to or recorded in the name of any
Participant until such Participant agrees to be bound by and executes the Management Unit Holders’ Agreement and any Unit Option Grant Agreement. 

4.11 Amendment of Terms of Options. The Committee may, in its sole discretion, amend the Plan or terms of any Option, provided, however,
that any such amendment shall not impair or adversely affect the Participants’ existing rights under the Plan or such Option without such Participant’s written consent. 

4.12 Adjustment Upon Changes in Membership Units. 

4.12.1 Increase or Decrease in Issued Membership Units Without Consideration. Subject to any required action by the Unit Holders of the Company, in the
event of any increase or decrease in the number of issued Membership Units resulting from a subdivision or consolidation of Membership Units, or any other increase or decrease in the number of such membership units effected without receipt of
consideration by the Company, the Committee shall make such adjustments to prevent the enlargement or dilution of rights with respect to the number of Membership Units subject to grant under this Plan, the number of Membership Units subject to the
Options and/or the Exercise Price per Membership Unit. 
 4.12.2 Certain Mergers. Subject to any required action by the Unit Holders of the Company,
in the event that the Company shall be the surviving corporation in any merger or consolidation (except a merger or consolidation as a result of which the holders of Membership Units receive securities of another corporation), the Options
outstanding on the date of such merger or consolidation shall pertain to and apply to the securities that a holder of the number of Membership Units subject to any such Option would have received in such merger or consolidation (it being understood
that if, in connection with such transaction, the Unit Holders of the Company retain their Membership Units and are not entitled to any additional or other consideration, the Options shall not be affected by such transaction). 

4.12.3 Certain Other Transactions. Except as otherwise provided in a Participant’s Unit Option Grant Agreement, in the event of (i) a
dissolution or liquidation of the Company, (ii) a sale of all or substantially all of the Company’s assets, (iii) a merger or consolidation involving the Company in which the Company is not the surviving corporation or (iv) a
merger or consolidation involving the Company in which the Company is the surviving corporation but the holders of Membership Units receive securities of another corporation and/or 

  
 11 

 
other property, including cash, the Committee shall, in its sole discretion, (a) have the power to provide for the exchange of each Option outstanding immediately prior to such event
(whether or not then exercisable) for an option on some or all of the property for which the membership units underlying such Options are exchanged and, incident thereto, make an equitable adjustment, as determined by the Committee, in the exercise
price of the options, or the number or kind of securities or amount of property subject to the options and/or, (b) if appropriate, cancel, effective immediately prior to such event, any outstanding Option (whether or not exercisable or vested)
and in full consideration of such cancellation pay to the Participant an amount in cash, with respect to each underlying Membership Unit, equal to the excess of (1) the value, as determined by the Committee in its sole discretion of securities
and/or property (including cash) received by such holders of Membership Units as a result of such event over (2) the Exercise Price, as the Committee may consider appropriate to prevent dilution or enlargement of rights. 

4.12.4 Other Changes. In the event of any change in the capitalization of the Company or a corporate change other than those specifically referred to
in Sections 4.12.1 through 4.12.3 hereof, or in the event a Public Market exists for the securities of any Affiliate of the Company, the Committee shall, in its good faith discretion, make such adjustments in the number and kind of shares or
securities subject to Options outstanding on the date on which such change occurs and in the per-share Exercise Price of each such Option, as the Committee may consider appropriate, to prevent dilution or
enlargement of rights. In such event, references to Membership Units herein shall be deemed to be a reference to such other kind of shares or securities subject to Options hereunder. 

4.12.5 No Other Rights. Except as expressly provided in the Plan or the Unit Option Grant Agreements evidencing the Options, the Participants shall not
have any rights as a holder of Options by reason of (i) any subdivision or consolidation of Membership Units or any other securities of any class, (ii) the payment of any distribution, any increase or decrease in the number of Membership
Units, or (iii) any dissolution, liquidation, merger or consolidation of the Company or any other corporation. Except as expressly provided in the Plan or the Unit Option Grant Agreements evidencing the Options, no issuance by the Company of
Membership Units or shares of common stock or shares of any class, or securities convertible into Membership Units or shares of common stock or shares of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the
number of Membership Units subject to the Options or the Exercise Price of such Options. 
 4.12.6 Tax Requirements. Any adjustments or changes to
the Options or Membership Units pursuant to this Section 4.12 shall be made in accordance with any applicable requirements of Section 409A of the Code and any guidance issued thereunder. 

    5.      Miscellaneous  

5.1 Rights as Unit Holders. The Participants shall not have any rights as Unit Holders with respect to any Membership Units covered by or
relating to the Options granted pursuant to the Plan until the date the Participants become the registered owners of such membership units. Except as otherwise expressly provided in Sections 4.11 and 4.12 hereof, no adjustment to the Options shall
be made for dividends or other rights for which the record date occurs prior to the effective date such stock is registered. 

  
 12 

 5.2 No Special Employment Rights. Nothing contained in the Plan shall confer upon the Participants
any right with respect to the continuation of their Employment or interfere in any way with the right of the Company or an Affiliate, subject to the terms of any separate Employment agreements to the contrary, at any time to terminate such
Employment or to increase or decrease the compensation of the Participants from the rate in existence at the time of the grant of any Option. 
 5.3
No Obligation to Exercise. The Grant to the Participants of the Options shall impose no obligation upon the Participants to exercise such Options. 

5.4 Restrictions on Membership Units. The rights and obligations of the Participants with respect to the Membership Units obtained through the
exercise of any Option provided in the Plan shall be governed by the terms and conditions of the Management Unit Holders’ Agreement.
