 Exhibit 4.1 

WESTERN DIGITAL CORPORATION 

AMENDED AND RESTATED 

2004 PERFORMANCE INCENTIVE PLAN 

(Amended and Restated as of August 5, 2015) 
  

	1.	PURPOSE OF PLAN 

 The purpose of this Western Digital Corporation 2004 Performance
Incentive Plan (this “Plan”) of Western Digital Corporation, a Delaware corporation (the “Corporation”), is to promote the success of the Corporation and to increase stockholder value by providing an additional
means through the grant of awards to attract, motivate, retain and reward selected employees and other eligible persons. 
  

	2.	ELIGIBILITY 

 The Administrator (as such term is defined in Section 3.1) may grant
awards under this Plan only to those persons that the Administrator determines to be Eligible Persons. An “Eligible Person” is any person who is either: (a) an officer (whether or not a director) or employee of the Corporation
or one of its Subsidiaries; (b) a member of the Board; or (c) an individual consultant or advisor who renders or has rendered bona fide services (other than services in connection with the offering or sale of securities of the Corporation
or one of its Subsidiaries in a capital-raising transaction or as a market maker or promoter of securities of the Corporation or one of its Subsidiaries) to the Corporation or one of its Subsidiaries and who is selected to participate in this Plan
by the Administrator; provided, however, that a person who is otherwise an Eligible Person under clause (c) above may participate in this Plan only if such participation would not adversely affect either the Corporation’s eligibility to
use Form S-8 to register under the Securities Act of 1933, as amended (the “Securities Act”), the offering and sale of shares issuable under this Plan by the Corporation or the Corporation’s compliance with any other applicable
laws. An Eligible Person who has been granted an award (a “participant”) may, if otherwise eligible, be granted additional awards if the Administrator shall so determine. As used herein, “Subsidiary” means any corporation
or other entity a majority of whose outstanding voting stock or voting power is beneficially owned directly or indirectly by the Corporation; and “Board” means the Board of Directors of the Corporation. 

 

	3.	PLAN ADMINISTRATION 

  

	 	3.1	 The Administrator. This Plan shall be administered by and all awards under this Plan shall be authorized by the Administrator.
The “Administrator” means the Board or one or more committees appointed by the Board or another committee (within its delegated authority) to administer all or certain aspects of this Plan. Any such committee shall be comprised
solely of one or more directors or such number of directors as may be required under applicable law. A committee may delegate some or all of its authority to another committee so constituted. The Board or a committee comprised solely of directors
may also delegate, to the extent permitted by Section 157(c) of the Delaware General Corporation Law and any other applicable law, to one or more officers of the Corporation, its powers

  
 1 

	 	
under this Plan (a) to designate the officers and employees of the Corporation and its Subsidiaries who will receive grants of awards under this Plan, and (b) to determine the number of
shares subject to, and the other terms and conditions of, such awards. The Board may delegate different levels of authority to different committees with administrative and grant authority under this Plan. Unless otherwise provided in the Bylaws of
the Corporation or the applicable charter of any Administrator: (x) a majority of the members of the acting Administrator shall constitute a quorum, and (y) the vote of a majority of the members present assuming the presence of a quorum or
the unanimous written consent of the members of the Administrator shall constitute action by the acting Administrator. 

  

	 	3.2	Powers of the Administrator. Subject to the express provisions of this Plan, the Administrator is authorized and empowered to do all things necessary or desirable in connection with the
authorization of awards and the administration of this Plan (in the case of a committee or delegation to one or more officers, within the authority delegated to that committee or person(s)), including, without limitation, the authority to:

  

	 	(a)	determine eligibility and, from among those persons determined to be eligible, the particular Eligible Persons who will receive an award under this Plan; 

 

	 	(b)	grant awards to Eligible Persons, determine the price (if any) at which securities will be offered or awarded and the number of securities to be offered or awarded to any of such persons (in the case of securities-based
awards), determine the other specific terms and conditions of such awards consistent with the express limits of this Plan, establish the installment(s) (if any) in which such awards shall become exercisable or shall vest (which may include, without
limitation, performance and/or time-based schedules), or determine that no delayed exercisability or vesting is required (subject to the minimum vesting rules of Section 5.1.5), establish any applicable performance-based exercisability or
vesting requirements, determine the extent (if any) to which any applicable exercise and vesting requirements have been satisfied, and establish the events (if any) of termination or reversion of such awards; 

 

	 	(c)	approve the forms of award agreements (which need not be identical either as to type of award or among participants); 

  

	 	(d)	construe and interpret this Plan and any agreements defining the rights and obligations of the Corporation, its Subsidiaries, and participants under this Plan, make any and all determinations necessary under this Plan
and any such agreements, further define the terms used in this Plan, and prescribe, amend and rescind rules and regulations relating to the administration of this Plan or the awards granted under this Plan; 

  
 2 

	 	(e)	cancel, modify, or waive the Corporation’s rights with respect to, or modify, discontinue, suspend, or terminate any or all outstanding awards, subject to any required consent under Section 8.6.5;

  

	 	(f)	accelerate, waive or extend the vesting or exercisability, or modify or extend the term of any or all such outstanding awards (in the case of options or stock appreciation rights, within the maximum term of such awards)
in such circumstances as the Administrator may deem appropriate (including, without limitation, in connection with a termination of employment or services or other events of a personal nature) subject to any required consent under Section 8.6.5
and subject to the minimum vesting rules of Section 5.1.5; 

  

	 	(g)	adjust the number of shares of Common Stock subject to any award, adjust the price of any or all outstanding awards or otherwise waive or change previously imposed terms and conditions, in such circumstances as the
Administrator may deem appropriate, in each case subject to Sections 4 and 8.6 (and subject to the no repricing provision below); 

  

	 	(h)	determine the date of grant of an award, which may be a designated date after but not before the date of the Administrator’s action (unless otherwise designated by the Administrator, the date of grant of an award
shall be the date upon which the Administrator took the action granting an award); provided, that the grant date of any award may not be modified once such grant date has occurred; 

 

	 	(i)	determine whether, and the extent to which, adjustments are required pursuant to Section 7 hereof and authorize the termination, conversion, substitution or succession of awards upon the occurrence of an event of
the type described in Section 7; 

  

	 	(j)	acquire or settle (subject to Sections 7 and 8.6) rights under awards in cash, stock of equivalent value, or other consideration (subject to the no repricing provision below); and 

 

	 	(k)	determine the fair market value of the Common Stock or awards under this Plan from time to time and/or the manner in which such value will be determined. 

Notwithstanding the foregoing and except for an adjustment pursuant to Section 7.1 or a repricing approved by stockholders, in no case
may the Administrator (1) amend an outstanding stock option or SAR to reduce the exercise price or base price of the award, (2) cancel, exchange, or surrender an outstanding stock option or SAR in exchange for cash or other awards for the
purpose of repricing the award, or (3) cancel, exchange, or surrender an outstanding stock option or SAR in exchange for an option or SAR with an exercise or base price that is less than the exercise or base price of the original award. 

  
 3 

	 	3.3	Binding Determinations. Any determination or other action taken by, or inaction of, the Corporation, any Subsidiary, or the Administrator relating or pursuant to this Plan (or any award made under
this Plan) and within its authority hereunder or under applicable law shall be within the absolute discretion of that entity or body and shall be conclusive and binding upon all persons. Neither the Board nor any Board committee, nor any member
thereof or person acting at the direction thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with this Plan (or any award made under this Plan), and all such persons shall
be entitled to indemnification and reimbursement by the Corporation in respect of any claim, loss, damage or expense (including, without limitation, attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or
under any directors and officers liability insurance coverage that may be in effect from time to time. Neither the Board nor any Board committee, nor any member thereof or person acting at the direction thereof, nor the Corporation or any of its
Subsidiaries, shall be liable for any damages of a participant should an award or other action with respect thereto not satisfy Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
should an option intended as an ISO (as defined below) fail to actually meet the requirements of the Internal Revenue Code of 1986, as amended (the “Code”), applicable to ISOs, should any award fail to qualify for any intended tax
treatment or be subject to tax, penalty, or interest under Section 409A of the Code or other tax penalties, or otherwise for any tax or other liability imposed on a participant with respect to an award. 

 

	 	3.4	Reliance on Experts. In making any determination or in taking or not taking any action under this Plan, the Board or a committee, as the case may be, may obtain and may rely upon the advice of
experts, including employees and professional advisors to the Corporation. No director, officer or agent of the Corporation or any of its Subsidiaries shall be liable for any such action or determination taken or made or omitted in good faith.

  

	 	3.5	Delegation. The Administrator may delegate ministerial, non-discretionary functions to individuals who are officers or employees of the Corporation or any of its Subsidiaries or to third parties.

  

	4.	SHARES OF COMMON STOCK SUBJECT TO THE PLAN; SHARE LIMITS 

  

	 	4.1	Shares Available. Subject to the provisions of Section 7.1, the capital stock that may be delivered under this Plan shall be shares of the Corporation’s authorized but unissued Common
Stock and any shares of its Common Stock held as treasury shares. For purposes of this Plan, “Common Stock” shall mean the common stock of the Corporation and such other securities or property as may become the subject of awards
under this Plan, or may become subject to such awards, pursuant to an adjustment made under Section 7.1. 

 4.2
Share Limits. The maximum number of shares of Common Stock that may be delivered pursuant to awards granted to Eligible Persons under this Plan (the “Share Limit”) is 65,837,248. 

  
 4 

 Shares issued in respect of any “Full-Value Award” granted under this Plan shall be
counted against the foregoing Share Limit as 1.72 shares for every one share actually issued in connection with such award. For this purpose, a “Full-Value Award” means any award under this Plan that is not a stock option
grant or a stock appreciation right grant. 
 The following limits also apply with respect to awards granted under this Plan: 

 

	 	(1)	The maximum number of shares of Common Stock that may be delivered pursuant to options qualified as incentive stock options granted under this Plan is 65,837,248 shares. 

 

	 	(2)	The maximum number of shares of Common Stock subject to those options and stock appreciation rights that are granted during any calendar year to any individual under this Plan is 1,000,000 shares. 

 

	 	(3)	Additional limits with respect to Qualified Performance-Based Awards are set forth in Section 5.2.3. 

  

	 	(4)	In no event will greater than five percent (5%) of the total shares of Common Stock available for award grant purposes under this Plan be used for purposes of granting certain “Special Full-Value Awards”
referred to in Section 5.1.5. 

  

	 	(5)	In no event shall the value (based on the fair market value of the shares on the date of grant of the applicable award, using such valuation principles as determined by the Administrator) of the shares of Common Stock
subject to awards granted under this Plan to any one non-employee member of the Board (a “Non-Employee Director”) in any one Grant Year exceed $900,000. The limit in the preceding sentence shall not apply as to any award granted to
an individual for services in a capacity other than as a Non-Employee Director, even if such individual is, was or becomes a Non-Employee Director. For this purpose, “Grant Year” means the annual period commencing on the date of the
Corporation’s annual meeting of stockholders and concluding on the day immediately preceding the next annual meeting of stockholders, or such other annual period as the Administrator may determine in its discretion. 

Each of the foregoing numerical limits is subject to adjustment as contemplated by Section 4.3, Section 7.1, and Section 8.10.

  

	 	4.3	Awards Settled in Cash, Reissue of Awards and Shares. The share limits of this Plan are subject to adjustment pursuant to the following provisions of this Section 4.3, subject to any applicable
limitations under Section 162(m) of the Code with respect to awards intended to qualify as performance-based compensation thereunder. Refer to Section 8.10 for application of this Plan’s share limits with respect to assumed awards.

  

	 	(a)	Shares that are subject to or underlie awards which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under this Plan shall again be
available for subsequent awards under this Plan. 

  
 5 

	 	(b)	Shares that are exchanged by a participant or withheld by the Corporation as full or partial payment in connection with any award under this Plan, shares exchanged by a participant or withheld by the Corporation or one
of its Subsidiaries to satisfy the tax withholding obligations related to any award, and shares purchased on the open market with the cash proceeds from the exercise of options, shall not be available for subsequent awards under this Plan.

  

	 	(c)	To the extent that an award is settled in cash or a form other than shares of Common Stock, the shares that would have been delivered had there been no such cash or other settlement shall not be counted against the
shares available for issuance under this Plan. 

  

	 	(d)	In the event that shares of Common Stock are delivered in respect of a dividend equivalent right, only the actual number of shares delivered with respect to the award shall be counted against the share limits of this
Plan. To the extent that shares of Common Stock are delivered pursuant to the exercise of a stock appreciation right or stock option, the number of underlying shares as to which the exercise related shall be counted against the applicable share
limits under Section 4.2, as opposed to only counting the shares actually issued. (For purposes of clarity, if a stock appreciation right relates to 100,000 shares and is exercised at a time when the payment due to the participant is 15,000
shares, 100,000 shares shall be charged against the applicable share limits under Section 4.2 with respect to such exercise.) 

  

	 	4.4	No Fractional Shares. No fractional shares shall be delivered under this Plan. The Administrator may pay cash in lieu of any fractional shares in settlements of awards under this Plan.

  

	5.	AWARDS 

  

	 	5.1	Type and Form of Awards. The Administrator shall determine the type or types of award(s) to be made to each selected Eligible Person. Awards may be granted singly, in combination or in tandem.
Awards also may be made in combination or in tandem with, in replacement of, as alternatives to, or as the payment form for grants or rights under any other employee or compensation plan of the Corporation or one of its Subsidiaries. The types of
awards that may be granted under this Plan are: 

 5.1.1    Stock Options. A stock
option is the grant of a right to purchase a specified number of shares of Common Stock during a specified period as determined by the Administrator. An option may be intended as an incentive 

  
 6 

 
stock option within the meaning of Section 422 of the Code (an “ISO”) or a nonqualified stock option (an option not intended to be an ISO). The award agreement for an option
will indicate if the option is intended as an ISO; otherwise it will be deemed to be a nonqualified stock option. The maximum term of each option (ISO or nonqualified) shall be ten (10) years. The per share exercise price for each option shall
be not less than 100% of the fair market value of a share of Common Stock on the date of grant of the option. When an option is exercised, the exercise price for the shares to be purchased shall be paid in full in cash or such other method permitted
by the Administrator consistent with Section 5.5. 
 5.1.2    Additional Rules Applicable to ISOs.
To the extent that the aggregate fair market value (determined at the time of grant of the applicable option) of stock with respect to which ISOs first become exercisable by a participant in any calendar year exceeds $100,000, taking into account
both Common Stock subject to ISOs under this Plan and stock subject to ISOs under all other plans of the Corporation or one of its Subsidiaries (or any parent or predecessor corporation to the extent required by and within the meaning of
Section 422 of the Code and the regulations promulgated thereunder), such options shall be treated as nonqualified stock options. In reducing the number of options treated as ISOs to meet the $100,000 limit, the most recently granted options
shall be reduced first. To the extent a reduction of simultaneously granted options is necessary to meet the $100,000 limit, the Administrator may, in the manner and to the extent permitted by law, designate which shares of Common Stock are to be
treated as shares acquired pursuant to the exercise of an ISO. ISOs may only be granted to employees of the Corporation or one of its subsidiaries (for this purpose, the term “subsidiary” is used as defined in Section 424(f) of the
Code, which generally requires an unbroken chain of ownership of at least 50% of the total combined voting power of all classes of stock of each subsidiary in the chain beginning with the Corporation and ending with the subsidiary in question). No
ISO may be granted to any person who, at the time the option is granted, owns (or is deemed to own under Section 424(d) of the Code) shares of outstanding Common Stock possessing more than 10% of the total combined voting power of all classes
of stock of the Corporation, unless the exercise price of such option is at least 110% of the fair market value of the stock subject to the option and such option by its terms is not exercisable after the expiration of five years from the date such
option is granted. If an otherwise intended ISO fails to meet the applicable requirements of Section 422 of the Code, the option shall be rendered a nonqualified stock option. 

5.1.3    Stock Appreciation Rights. A stock appreciation right or “SAR” is a right
to receive a payment, in cash and/or Common Stock, equal to the excess of the fair market value of a specified number of shares of Common Stock on the date the SAR is exercised over the “base price” of the award, which base price shall not
be less than the fair market value of a share of Common Stock on the date the SAR was granted and shall be set forth in the applicable award agreement. The maximum term of a SAR shall be ten (10) years. 

  
 7 

 5.1.4    Other Awards. The other types of awards that
may be granted under this Plan include: (a) stock bonuses, restricted stock, performance stock, stock units, phantom stock, dividend equivalents, or similar rights to purchase or acquire shares, whether at a fixed or variable price (or no
price) or fixed or variable ratio related to the Common Stock, and any of which may (but need not) be fully vested at grant or vest upon the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other
conditions, or any combination thereof; or (b) cash awards. Dividend equivalent rights may be granted as a separate award or in connection with another award under this Plan; provided, however, that dividend equivalent rights may not be granted
in connection with a stock option or SAR granted under this Plan. In addition, any dividends and/or dividend equivalents as to the unvested portion of a restricted stock award that is subject to performance-based vesting requirements or the unvested
portion of a stock unit award that is subject to performance-based vesting requirements will be subject to termination and forfeiture to the same extent as the corresponding portion of the award to which they relate in the event the applicable
performance-based vesting conditions are not satisfied. 
 5.1.5    Minimum Vesting Requirements.
Except for any accelerated vesting required or permitted pursuant to Section 7 and except as otherwise provided in the following provisions of this Section 5.1.5, and subject to such additional vesting requirements or conditions as the
Administrator may establish with respect to the award, each award granted under this Plan that is a Full-Value Award and payable in shares of Common Stock shall be subject to the following minimum vesting requirements: (a) if the award includes
a performance-based vesting condition, the award shall not vest earlier than the first anniversary of the date of grant of the award and vesting shall occur only if the award holder is employed by, a director of, or otherwise providing services to
the Corporation or one of its Subsidiaries on such vesting date; and (b) if the award does not include a performance-based vesting condition, the award shall not vest more rapidly than in monthly installments over the three-year period
immediately following the date of grant of the award and vesting of any vesting installment of the award shall occur only if the award holder is employed by, a director of, or otherwise providing services to the Corporation or one of its
Subsidiaries on the date such installment is scheduled to vest; provided that the Administrator may accelerate or provide in the applicable award agreement for the accelerated vesting of any Full-Value Award in connection with a change in control of
the award holder’s employer (or a parent thereof) in accordance with the Plan, the termination of the award holder’s service (including a termination of service due to the award holder’s death, disability or retirement, but not
including a termination of service by the award holder’s employer for cause), or as consideration or partial consideration for a release by the award holder of pending or threatened claims against the Corporation, the award holder’s
employer, or any of their respective officers, directors or other affiliates (regardless of whether the release is given in connection with a termination of service by the award holder’s employer for cause or other circumstances). The
Administrator may, however, accelerate or provide in the applicable award agreement for the accelerated vesting of any Full-Value Award in circumstances not contemplated by the preceding sentence, and/or provide for a vesting schedule that is

  
 8 

 
shorter than the minimum schedule contemplated by the preceding sentence, in such circumstances as the Administrator may deem appropriate; provided, however, that the portion of any such
Full-Value Award that vests earlier than the minimum vesting dates that would be applicable pursuant to the minimum vesting requirements of the preceding sentence (or, as to any accelerated vesting, provides for accelerated vesting other than in the
circumstances contemplated by the preceding sentence) shall count against the applicable share limits of Section 4.2 as a Special Full-Value Award (as opposed to counting against such limits only as a Full-Value Award). 

 

	 	5.2	Section 162(m) Performance-Based Awards. Without limiting the generality of the foregoing, any of the types of awards listed in Section 5.1.4 above may be granted as awards intended
to satisfy the requirements for “performance-based compensation” within the meaning of Section 162(m) of the Code. An award (other than an option or SAR) intended by the Administrator to satisfy the requirements for
“performance-based compensation” within the meaning of Section 162(m) of the Code is referred to as a “Qualified Performance-Based Awards.” An option or SAR intended to satisfy the requirements for
“performance-based compensation” within the meaning of Section 162(m) of the Code is referred to as a “Qualifying Option” or “Qualifying SAR,” respectively. The grant, vesting, exercisability or
payment of Qualified Performance-Based Awards may depend (or, in the case of Qualifying Options or Qualifying SARs, may also depend) on the degree of achievement of one or more performance goals relative to a pre-established targeted level or levels
using one or more of the Business Criteria set forth below (on an absolute or relative (including, without limitation, relative to the performance of one or more other companies or upon comparisons of any of the indicators of performance relative to
one or more other companies) basis) for the Corporation on a consolidated basis or for one or more of the Corporation’s subsidiaries, segments, divisions or business units, or any combination of the foregoing. Any Qualified Performance-Based
Award shall be subject to all of the following provisions of this Section 5.2, and a Qualifying Option or Qualifying SAR shall be subject to the following provisions of this Section 5.2 only to the extent expressly provided below. Nothing
in this Plan, however, requires the Administrator to qualify any award or compensation as “performance-based compensation” under Section 162(m) of the Code. 

5.2.1    Class; Administrator. The eligible class of persons for Qualified Performance-Based
Awards under this Section 5.2, as well as Qualifying Options and Qualifying SARs, shall be officers and employees of the Corporation or one of its Subsidiaries. To qualify awards as performance-based under Section 162(m), the Administrator
approving Qualified Performance-Based Awards or Qualifying Options or Qualifying SARs, or making any certification required pursuant to Section 5.2.4, must consist of a committee consisting solely of two or more outside directors (as this
requirement is applied under Section 162(m) of the Code). 

  
 9 

 5.2.2    Performance Goals.  

 

	 	(a)	The specific performance goals for Qualified Performance-Based Awards (other than Qualifying Options and Qualifying SARs) shall be, on an absolute or relative basis, established based on one or more of the following
business criteria (“Business Criteria”) as selected by the Administrator in its sole discretion: (i) earnings per share, (ii) adjusted earnings per share, (iii) cash flow (which means cash and cash equivalents derived
from either net cash flow from operations or net cash flow from operations, financing and investing activities), (iv) stock price, (v) total stockholder return, (vi) gross or net sales or revenue, (vii) revenue growth,
(viii) operating income (before or after taxes), (ix) net earnings (before or after interest, taxes, depreciation and/or amortization), (x) return on equity, assets, capital or net investment, (xi) cost or expense containment or
reduction, (xii) market share or total available market, (xiii) economic value added, (xiv) gross margin or adjusted gross margin, (xv) net income, or any combination thereof. To qualify awards as performance-based under
Section 162(m) of the Code, the applicable Business Criterion (or Business Criteria, as the case may be) and specific performance formula, goal or goals (“targets”) must be established and approved by the Administrator during the
first 90 days of the performance period (and, in the case of performance periods of less than one year, in no event after 25% or more of the performance period has elapsed) and while performance relating to such target(s) remains substantially
uncertain within the meaning of Section 162(m) of the Code. The applicable performance measurement period may not be less than three months nor more than 10 years. 

 

	 	(b)	 Performance targets for Qualified Performance-Based Awards shall be adjusted to mitigate the unbudgeted impact of significant, material, unusual or
nonrecurring items, accounting changes and extraordinary events not foreseen at the time the targets were set unless the Administrator provides otherwise at the time of establishing the targets. By way of example, such adjustment items may include,
but are not limited to, one or more of the following: (i) items related to a change in accounting principle, (ii) items relating to financing activities, (iii) expenses for restructuring or productivity initiatives, (iv) other
non-operating items, (v) items related to acquisitions, (vi) items attributable to the business operations of any entity acquired by the Corporation during the performance period, (vii) items related to the disposal of a business or
segment of a business, (viii) items related to discontinued operations that do not qualify as a segment of a business under applicable accounting standards, (ix) items attributable to any stock dividend, stock split, combination or
exchange of stock occurring during the performance period, (x) any other items of significant income or expense, (xi) items relating to unusual or extraordinary corporate transactions, events or developments, (xii) items related to
amortization of acquired intangible assets, (xiii) items that are outside the scope of core, on-going business activities, (xiv) items related to acquired in-process research and development, (xv) items relating to changes in tax
laws, (xvi) items relating to licensing or partnership arrangements, (xvii) items relating to asset impairment charges, (xviii) items relating to gains or losses for litigation, arbitration and contractual settlements, or
(xix) items relating to any 

  
 10 

	 	
other unusual or nonrecurring events or changes in applicable law or business conditions. 

5.2.3    Form of Payment; Maximum Qualified Performance-Based Award. Grants or awards under
this Section 5.2 may be paid in cash or shares of Common Stock or any combination thereof. Grants of Qualifying Options and Qualifying SARs to any one participant in any one calendar year shall be subject to the limit set forth in
Section 4.2(2). The maximum number of shares of Common Stock which may be subject to Qualified Performance-Based Awards (other than Qualifying Options and Qualifying SARs, but including Qualified Performance-Based Awards payable in shares of
Common Stock and Qualified Performance-Based Awards payable in cash where the amount of cash payment upon or following vesting of the award is determined with reference to the fair market value of a share of Common Stock) that are granted to any one
participant in any one calendar year shall not exceed 800,000 shares, either individually or in the aggregate, subject to adjustment as provided in Section 7.1. The aggregate amount of compensation to be paid to any one participant in respect
of all Qualified Performance-Based Awards payable only in cash (excluding cash awards covered by the preceding sentence where the cash payment is determined with reference to the fair market value of a share of Common Stock upon or following the
vesting of the award) granted to that participant in any one calendar year shall not exceed $10,000,000. Awards that are cancelled during the year shall be counted against these limits to the extent required by Section 162(m) of the Code. 

5.2.4    Certification of Payment. Before any Qualified Performance-Based Award (other than
Qualifying Options and Qualifying SARs) is paid and to the extent applicable to qualify the award as performance-based compensation within the meaning of Section 162(m) of the Code, the Administrator must certify in writing that the performance
target(s) and any other material terms of the Qualified Performance-Based Award were satisfied. 

5.2.5    Reservation of Discretion. The Administrator will have the discretion to determine
the restrictions or other limitations of the individual awards granted under this Section 5.2 including the authority to reduce awards, payouts or vesting or to pay no awards, in its sole discretion, if the Administrator preserves such
authority at the time of grant by language to this effect in its authorizing resolutions or otherwise. 

5.2.6    Expiration of Grant Authority. As required pursuant to Section 162(m) of the
Code and the regulations promulgated thereunder, the Administrator’s authority to grant new awards that are intended to qualify as performance-based compensation within the meaning of Section 162(m) of the Code (other than Qualifying
Options and Qualifying SARs) shall terminate upon the first meeting of the Corporation’s stockholders that occurs in the fifth year following the year in which the Corporation’s stockholders approve this restatement of the Plan, subject to
any subsequent extension that may be approved by stockholders. 

  
 11 

	 	5.3	Award Agreements. Each award shall be evidenced by either (1) a written award agreement in a form approved by the Administrator, or (2) an electronic notice of award grant in a form
approved by the Administrator and recorded by the Corporation (or its designee) in an electronic recordkeeping system used for the purpose of tracking award grants under this Plan generally (in each case, an “award agreement”), as the
Administrator may provide and, in each case and if required by the Administrator, executed or otherwise electronically accepted (including deemed acceptance) by the recipient of the award in such form and manner as the Administrator may require. The
Administrator may authorize any officer of the Corporation (other than the particular award recipient) to execute any or all award agreements on behalf of the Corporation. The award agreement shall set forth the material terms and conditions of the
award as established by the Administrator consistent with the express limitations of this Plan. 

  

	 	5.4	Deferrals and Settlements. Payment of awards may be in the form of cash, Common Stock, other awards or combinations thereof as the Administrator shall determine, and with such restrictions (if any)
as it may impose, as set forth in the applicable award agreement. The Administrator may also require or permit participants to elect to defer the issuance of shares or the settlement of awards in cash under such rules and procedures as it may
establish under this Plan and in accordance with the applicable award agreement. The Administrator may also provide that deferred settlements include the payment or crediting of interest or other earnings on the deferral amounts, or the payment or
crediting of dividend equivalents where the deferred amounts are denominated in shares. 

  

	 	5.5	Consideration for Common Stock or Awards. The purchase price (if any) for any award granted under this Plan or the Common Stock to be delivered pursuant to an award, as applicable, may be paid by
means of any lawful consideration as determined by the Administrator, including, without limitation, one or a combination of the following methods: 

  

	 	●	 	a reduction in compensation otherwise payable to the recipient of such award or for services rendered by the recipient; 

  

	 	●	 	cash, check payable to the order of the Corporation, or electronic funds transfer; 

  

	 	●	 	notice and third party payment in such manner as may be authorized by the Administrator; 

  

	 	●	 	the delivery of previously owned shares of Common Stock; 

  

	 	●	 	by a reduction in the number of shares otherwise deliverable pursuant to the award; or 

  

	 	●	 	subject to such procedures as the Administrator may adopt, pursuant to a “cashless exercise” with a third party who provides financing for the purposes of (or who otherwise facilitates) the purchase or
exercise of awards, including through same-day sales. 

  
 12 

 In no event shall any shares newly-issued by the Corporation be issued for less than the minimum
lawful consideration for such shares or for consideration other than consideration permitted by applicable state law. The Corporation will not be obligated to deliver any shares unless and until it receives full payment of the exercise or purchase
price therefor and any related withholding obligations under Section 8.5 and any other conditions to exercise or purchase have been satisfied. Unless otherwise expressly provided in the applicable award agreement, the Administrator may at any
time eliminate or limit a participant’s ability to pay any purchase or exercise price of any award or shares by any method other than cash payment to the Corporation. 
  

	 	5.6	Definition of Fair Market Value.  For purposes of this Plan, “fair market value” shall mean, unless otherwise determined or provided by the Administrator in the circumstances,
the closing price (in regular trading) of a share of Common Stock on the NASDAQ Stock Market (or, if the Common Stock is not then traded on the NASDAQ Stock Market, on the principal national securities exchange on which the Common Stock is then
listed or admitted to trade) (the “Exchange”) for the date in question or, if no sales of Common Stock were made on the Exchange on that date, the closing price (in regular trading) of a share of Common Stock on the Exchange for the
next preceding day on which sales of Common Stock were made on the Exchange. The Administrator may, however, provide with respect to one or more awards that the fair market value shall equal the last closing price (in regular trading) of a share of
Common Stock on the Exchange available at the relevant time or the average of the high and low trading prices of a share of Common Stock on the Exchange for the date in question or the most recent trading day. If the Common Stock is no longer listed
or is no longer actively traded on the Exchange as of the applicable date, the fair market value of the Common Stock shall be the value as reasonably determined by the Administrator for purposes of the award in the circumstances. The Administrator
also may adopt a different methodology for determining fair market value with respect to one or more awards if a different methodology is necessary or advisable to secure any intended favorable tax, legal or other treatment for the particular
award(s) (for example, and without limitation, the Administrator may provide that fair market value for purposes of one or more awards will be based on an average of closing prices (or the average of high and low daily trading prices) for a
specified period preceding the relevant date). 

  

	 	5.7	Transfer Restrictions. 

5.7.1    Limitations on Exercise and Transfer.  Unless otherwise expressly provided in (or
pursuant to) this Section 5.7, by applicable law and by the award agreement, as the same may be amended, (a) all awards are non-transferable and shall not be subject in any manner to sale, transfer, anticipation, alienation, assignment,
pledge, encumbrance or charge; (b) awards shall be exercised only by the participant; and (c) amounts payable or shares issuable pursuant to any award shall be delivered only to (or for the account of) the participant. 

  
 13 

 5.7.2    Exceptions.  The Administrator may
permit awards to be transferred to other persons or entities pursuant to such conditions and procedures, including limitations on subsequent transfers, as the Administrator may, in its sole discretion, establish in writing; provided, however, that
any such transfer shall only be permitted if it is made by the participant for estate or tax planning or charitable purposes for no (or nominal) consideration, as determined by the Administrator. Any permitted transfer shall be subject to compliance
with applicable federal and state securities laws. 
 5.7.3    Further Exceptions to Limits on
Transfer.  The exercise and transfer restrictions in Section 5.7.1 shall not apply to: 
  

	 	(a)	transfers to the Corporation, 

  

	 	(b)	the designation of a beneficiary to receive benefits in the event of the participant’s death or, if the participant has died, transfers to or exercise by the participant’s beneficiary, or, in the absence of a
validly designated beneficiary, transfers by will or the laws of descent and distribution, 

  

	 	(c)	subject to any applicable limitations on ISOs and to such procedures as the Administrator may prescribe, transfers to a family member (or former family member) pursuant to a domestic relations order, 

 

	 	(d)	if the participant has suffered a disability, permitted transfers or exercises on behalf of the participant by his or her legal representative, or 

 

	 	(e)	the authorization by the Administrator of “cashless exercise” procedures with third parties who provide financing for the purpose of (or who otherwise facilitate) the exercise of awards consistent with
applicable laws and the express authorization of the Administrator. 

  

	 	5.8	International Awards.  One or more awards may be granted to Eligible Persons who provide services to the Corporation or one of its Subsidiaries outside of the United States. Any awards
granted to such persons may be granted pursuant to the terms and conditions of any applicable sub-plans, if any, appended to this Plan and approved by the Administrator. 

 

	6.	EFFECT OF TERMINATION OF SERVICE ON AWARDS 

  

	 	6.1	 General.  The Administrator shall establish the effect (if any) of a termination of employment or service on the rights
and benefits under each award under this Plan and in so doing may make distinctions based upon, inter alia, the cause of termination and type of award. If the participant is not an employee of the Corporation or one of its Subsidiaries and provides
other services to the Corporation or one of its Subsidiaries, the Administrator shall be the sole judge for purposes of this Plan (unless a contract or the award otherwise provides) of whether the participant continues to

  
 14 

	 	
render services to the Corporation or one of its Subsidiaries and the date, if any, upon which such services shall be deemed to have terminated. 

 

	 	6.2	Events Not Deemed Terminations of Service.  Unless the express policy of the Corporation or one of its Subsidiaries, or the Administrator, otherwise provides, or except as otherwise
required by applicable law, the employment relationship shall not be considered terminated in the case of (a) sick leave, (b) military leave, or (c) any other leave of absence authorized by the Corporation or one of its Subsidiaries,
or the Administrator; provided that unless reemployment upon the expiration of such leave is guaranteed by contract or law or the Administrator otherwise provides, such leave is for a period of not more than three months. In the case of any employee
of the Corporation or one of its Subsidiaries on an approved leave of absence, continued vesting of the award while on leave from the employ of the Corporation or one of its Subsidiaries may be suspended until the employee returns to service, unless
the Administrator otherwise provides or applicable law otherwise requires. In no event shall an award be exercised after the expiration of the term set forth in the award agreement. 

 

	 	6.3	Effect of Change of Subsidiary Status.  For purposes of this Plan and any award, if an entity ceases to be a Subsidiary of the Corporation a termination of employment or service shall be
deemed to have occurred with respect to each Eligible Person in respect of such Subsidiary who does not continue as an Eligible Person in respect of the Corporation or another Subsidiary that continues as such after giving effect to the transaction
or other event giving rise to the change in status unless the Subsidiary that is sold, spun-off or otherwise divested (or its successor or a direct or indirect parent of such Subsidiary or successor) assumes the Eligible Person’s award(s) in
connection with such transaction. 

  

	7.	ADJUSTMENTS; ACCELERATION 

  

	 	7.1	Adjustments.  Subject to Section 7.2, upon (or, as may be necessary to effect the adjustment, immediately prior to): any reclassification, recapitalization, stock split (including a
stock split in the form of a stock dividend) or reverse stock split; any merger, combination, consolidation, or other reorganization; any spin-off, split-up, or similar extraordinary dividend distribution in respect of the Common Stock; or any
exchange of Common Stock or other securities of the Corporation, or any similar, unusual or extraordinary corporate transaction in respect of the Common Stock; then the Administrator shall equitably and proportionately adjust (1) the number and
type of shares of Common Stock (or other securities) that thereafter may be made the subject of awards (including the specific share limits, maximums and numbers of shares set forth elsewhere in this Plan), (2) the number, amount and type of
shares of Common Stock (or other securities or property) subject to any outstanding awards, (3) the grant, purchase, or exercise price (which term includes the base price of any SAR or similar right) of any outstanding awards, and/or
(4) the securities, cash or other property deliverable upon exercise or payment of any outstanding awards, in each case to the extent necessary to preserve (but not increase) the level of incentives intended by this Plan and the
then-outstanding awards. 

  
 15 

 Unless otherwise expressly provided in the applicable award agreement, upon (or, as may be
necessary to effect the adjustment, immediately prior to) any event or transaction described in the preceding paragraph or a sale of all or substantially all of the business or assets of the Corporation as an entirety, the Administrator shall
equitably and proportionately adjust the performance standards applicable to any then-outstanding performance-based awards to the extent necessary to preserve (but not increase) the level of incentives intended by this Plan and the then-outstanding
performance-based awards. 
 It is intended that, if possible, any adjustments contemplated by the preceding two paragraphs be made in a
manner that satisfies applicable U.S. legal, tax (including, without limitation and as applicable in the circumstances, Section 424 of the Code as to ISOs, Section 409A of the Code as to awards intended to comply therewith and not be
subject to taxation thereunder, and Section 162(m) of the Code as to any awarded intended as “performance-based compensation” thereunder) and accounting (so as to not trigger any unintended charge to earnings with respect to such
adjustment) requirements. 
 Without limiting the generality of Section 3.3, any good faith determination by the Administrator as to
whether an adjustment is required in the circumstances pursuant to this Section 7.1, and the extent and nature of any such adjustment, shall be conclusive and binding on all persons. 

 

	 	7.2	 Corporate Transactions - Assumption and Termination of Awards.  Upon any event in which the Corporation does not
survive, or does not survive as a public company in respect of its Common Stock (including, without limitation, a merger, combination, consolidation, or other reorganization; any exchange of Common Stock or other securities of the Corporation; a
sale of all or substantially all the business, stock or assets of the Corporation; a dissolution of the Corporation; or other event in which the Corporation does not survive or does not survive as a public company in respect of its Common Stock),
then the Administrator may make provision for a cash payment in settlement of, or for the assumption, substitution or exchange of any or all outstanding share-based awards or the cash, securities or property deliverable to the holder of any or all
outstanding share-based awards, based upon, to the extent relevant under the circumstances, the distribution or consideration payable to holders of the Common Stock upon or in respect of such event. Upon the occurrence of (or, as may be necessary to
effect such action, immediately prior to) any event described in the preceding sentence, then, unless the Administrator has made a provision for the substitution, assumption, exchange or other continuation or settlement of the award or the award
would otherwise continue in accordance with its terms in the circumstances: (1) subject to Section 7.5 and unless otherwise provided in the applicable award agreement, each then-outstanding option and SAR shall become fully vested, all
shares of restricted stock then outstanding shall fully vest free of restrictions, and each other award granted under this Plan that is then outstanding 

  
 16 

	 	
shall become payable to the holder of such award; and (2) each award shall terminate upon the related event; provided that the holder of an option or SAR shall be given reasonable advance
notice of the impending termination and a reasonable opportunity to exercise his or her outstanding vested options and SARs (after giving effect to any accelerated vesting required in the circumstances) in accordance with their terms before the
termination of such awards (except that in no case shall more than ten days’ notice of the impending termination be required and any acceleration of vesting and any exercise of any portion of an award that is so accelerated may be made
contingent upon the actual occurrence of the event). 

 The Administrator may adopt such valuation methodologies for
outstanding awards as it deems reasonable in the event of a cash or property settlement and, in the case of options, SARs or similar rights, but without limitation on other methodologies, may base such settlement solely upon the excess if any of the
per share amount payable upon or in respect of such event over the exercise or base price of the award. 
 Without limiting the generality
of Section 3.3, any good faith determination by the Administrator pursuant to its authority under this Section 7.2 shall be conclusive and binding on all persons. 
  

	 	7.3	Possible Acceleration of Awards.  Without limiting Section 7.2 or the Administrator’s broad authority to establish vesting provisions, in the event of a Change in Control Event
(as defined below), the Administrator may, in its discretion, provide that any outstanding option or SAR shall become fully vested, that any share of restricted stock then outstanding shall fully vest free of restrictions, and that any other award
granted under this Plan that is then outstanding shall be payable to the holder of such award. The Administrator may take such action with respect to all awards then outstanding or only with respect to certain specific awards identified by the
Administrator in the circumstances and may condition any such acceleration upon the occurrence of another event (such as, without limitation, a termination of the award holder’s service). For purposes of this Plan, “Change in Control
Event” means any of the following: 

  

	 	(a)	 Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act, a “Person”), alone or together with its
affiliates and associates, including any group of persons which is deemed a “person” under Section 13(d)(3) of the Exchange Act (other than the Corporation or any subsidiary thereof or any employee benefit plan (or related trust) of
the Corporation or any subsidiary thereof, or any underwriter in connection with a firm commitment public offering of the Corporation’s capital stock), becomes the “beneficial owner” (as such term is defined in Rule 13d-3 of the
Exchange Act, except that a person shall also be deemed the beneficial owner of all securities which such person may have a right to acquire, whether or not such right is presently exercisable, referred to herein as “Beneficially
Own” or “Beneficial Owner” as the context may require) of thirty-three and one third percent or more of (i) the then outstanding shares of the Corporation’s common stock (“Outstanding

  
 17 

	 	
Company Common Stock”) or (ii) securities representing thirty-three and one-third percent or more of the combined voting power of the Corporation’s then outstanding voting
securities (“Outstanding Company Voting Securities”) (in each case, other than an acquisition in the context of a merger, consolidation, reorganization, asset sale or other extraordinary transaction covered by, and which does not
constitute a Change in Control Event under, clause (c) below); 

  

	 	(b)	A change, during any period of two consecutive years, of a majority of the Board as constituted as of the beginning of such period, unless the election, or nomination for election by the Corporation’s stockholders,
of each director who was not a director at the beginning of such period was approved by vote of at least two-thirds of the Incumbent Directors then in office (for purposes hereof, “Incumbent Directors” shall consist of the directors
holding office as of the Effective Date and any person becoming a director subsequent to such date whose election, or nomination for election by the Corporation’s stockholders, is approved by a vote of at least a majority of the Incumbent
Directors then in office); 

  

	 	(c)	Consummation of any merger, consolidation, reorganization or other extraordinary transaction (or series of related transactions) involving the Corporation, a sale or other disposition of all or substantially all of the
assets of the Corporation, or the acquisition of assets or stock of another entity by the Corporation or any of its subsidiaries (each, a “Business Combination”), in each case unless, following such Business Combination,
(1) all or substantially all of the individuals and entities that were the Beneficial Owners of the Outstanding Company Common Stock and the Outstanding Company Voting Securities immediately prior to such Business Combination Beneficially Own,
directly or indirectly, more than 50% of the then-outstanding shares of common stock and the combined voting power of the then-outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the entity
resulting from such Business Combination (including, without limitation, an entity that, as a result of such transaction, owns the Corporation or all or substantially all of the Corporation’s assets directly or through one or more subsidiaries
(a “Parent”)), (2) no Person (excluding any entity resulting from such Business Combination or a Parent or any employee benefit plan (or related trust) of the Corporation or such entity resulting from such Business Combination
or Parent, and excluding any underwriter in connection with a firm commitment public offering of the Corporation’s capital stock) Beneficially Owns, directly or indirectly, more than thirty-three and one third percent of, respectively, the
then-outstanding shares of common stock of the entity resulting from such Business Combination or the combined voting power of the then-outstanding voting securities of such entity, and (3) at least a majority of the members of the board of
directors or trustees of the entity resulting from such Business Combination or a Parent were Incumbent Directors at the time of the execution of the initial agreement or of the action of the Board providing for such Business Combination; or

  

	 	(d)	The stockholders of the Corporation approve a plan of complete liquidation or dissolution of the Corporation (other than in the context of a merger, consolidation, reorganization, asset sale or other extraordinary
transaction covered by, and which does not constitute a Change in Control Event under, clause (c) above). 

  
 18 

	 	7.4	Other Acceleration Rules.  Any acceleration of awards pursuant to this Section 7 shall comply with applicable legal requirements and, if necessary to accomplish the purposes of the
acceleration or if the circumstances require, may be deemed by the Administrator to occur prior to the applicable event, provided that the original terms of the award will be reinstated if the event giving rise to the acceleration does not actually
occur. The Administrator may override the provisions of Section 7.2, 7.3 and 7.5 by express provision in the award agreement and may accord any Eligible Person a right to refuse any acceleration, whether pursuant to the award agreement or
otherwise, in such circumstances as the Administrator may approve. The portion of any ISO accelerated in connection with a Change in Control Event or any other action permitted hereunder shall remain exercisable as an ISO only to the extent the
applicable $100,000 limitation on ISOs is not exceeded. To the extent exceeded, the accelerated portion of the option shall be exercisable as a nonqualified stock option under the Code. 

 

	 	7.5	Golden Parachute Limitation.  Notwithstanding anything else contained in this Section 7 to the contrary and unless otherwise expressly provided by the Administrator, in no event shall an
award be accelerated under this Plan to an extent or in a manner which would not be fully deductible by the Corporation or one of its Subsidiaries for federal income tax purposes because of Section 280G of the Code, nor shall any payment
hereunder be accelerated to the extent any portion of such accelerated payment would not be deductible by the Corporation or one of its Subsidiaries because of Section 280G of the Code. If a participant would be entitled to benefits or payments
hereunder and under any other plan or program that would constitute “parachute payments” as defined in Section 280G of the Code, then the participant may by written notice to the Corporation designate the order in which such parachute
payments will be reduced or modified so that the Corporation or one of its Subsidiaries is not denied federal income tax deductions for any “parachute payments” because of Section 280G of the Code. 

 

	8.	OTHER PROVISIONS 

  

	 	8.1	 Compliance with Laws.  This Plan, the granting and vesting of awards under this Plan, the offer, issuance and delivery of
shares of Common Stock, the acceptance of promissory notes and/or the payment of money under this Plan or under awards are subject to compliance with all applicable federal, state, local and foreign laws, rules and regulations (including but not
limited to state and federal securities law and federal margin requirements) and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Corporation, be necessary or advisable in connection
therewith. The person acquiring any securities under this Plan will, if requested 

  
 19 

	 	
by the Corporation or one of its Subsidiaries, provide such assurances and representations to the Corporation or one of its Subsidiaries as the Administrator may deem necessary or desirable to
assure compliance with all applicable legal and accounting requirements. 

  

	 	8.2	No Rights to Award.  No person shall have any claim or rights to be granted an award (or additional awards, as the case may be) under this Plan, subject to any express contractual rights (set
forth in a document other than this Plan) to the contrary. 

  

	 	8.3	No Employment/Service Contract.  Nothing contained in this Plan (or in any other documents under this Plan or in any award) shall confer upon any Eligible Person or other participant any right
to continue in the employ or other service of the Corporation or one of its Subsidiaries, constitute any contract or agreement of employment or other service or affect an employee’s status as an employee at will, nor shall interfere in any way
with the right of the Corporation or one of its Subsidiaries to change a person’s compensation or other benefits, or to terminate his or her employment or other service, with or without cause. Nothing in this Section 8.3, however, is
intended to adversely affect any express independent right of such person under a separate employment or service contract other than an award agreement. 

  

	 	8.4	Plan Not Funded.  Awards payable under this Plan shall be payable in shares or from the general assets of the Corporation, and no special or separate reserve, fund or deposit shall be made to
assure payment of such awards. No participant, beneficiary or other person shall have any right, title or interest in any fund or in any specific asset (including shares of Common Stock, except as expressly otherwise provided) of the Corporation or
one of its Subsidiaries by reason of any award hereunder. Neither the provisions of this Plan (or of any related documents), nor the creation or adoption of this Plan, nor any action taken pursuant to the provisions of this Plan shall create, or be
construed to create, a trust of any kind or a fiduciary relationship between the Corporation or one of its Subsidiaries and any participant, beneficiary or other person. To the extent that a participant, beneficiary or other person acquires a right
to receive payment pursuant to any award hereunder, such right shall be no greater than the right of any unsecured general creditor of the Corporation. 

  

	 	8.5	Tax Withholding.  Upon any exercise, vesting, or payment of any award or upon the disposition of shares of Common Stock acquired pursuant to the exercise of an ISO prior to satisfaction of the
holding period requirements of Section 422 of the Code, or upon any other tax withholding event with respect to any award, arrangements satisfactory to the Corporation shall be made to provide for any taxes the Corporation or any of its
Subsidiaries may be required to withhold with respect to such award event or payment. Such arrangements may include (but are not limited to) any one of (or a combination of) the following: 

 

	 	(a)	The Corporation or one of its Subsidiaries shall have the right to require the participant (or the participant’s personal representative or beneficiary, as the case may be) to pay or provide for payment of at least
the minimum amount of any taxes which the Corporation or one of its Subsidiaries may be required to withhold with respect to such award event or payment. 

  
 20 

	 	(b)	The Corporation or one of its Subsidiaries shall have the right to deduct from any amount otherwise payable in cash (whether related to the award or otherwise) to the participant (or the participant’s personal
representative or beneficiary, as the case may be) the minimum amount of any taxes which the Corporation or one of its Subsidiaries may be required to withhold with respect to such award event or payment. 

In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock under this Plan, the
Administrator may in its sole discretion (subject to Section 8.1) require or grant (either at the time of the award or thereafter) to the participant the right to elect, pursuant to such rules and subject to such conditions as the Administrator
may establish, that the Corporation reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares, valued in a consistent manner at their fair market value or at the sales price in accordance with
authorized procedures for cashless exercises, necessary to satisfy the minimum applicable withholding obligation on exercise, vesting or payment (unless otherwise provided by the Administrator and such change does not trigger unintended accounting
consequences). The Corporation may, with the Administrator’s approval, accept one or more promissory notes from any Eligible Person in connection with taxes required to be withheld upon the exercise, vesting or payment of any award under this
Plan; provided that any such note shall be subject to terms and conditions established by the Administrator and the requirements of applicable law. 
  

	 	8.6	Effective Date, Termination and Suspension, Amendments. 

8.6.1    Effective Date.  This Plan is effective as of September 21, 2004, the date of its
initial approval by the Board (the “Effective Date”). The Amendment and Restatement of this Plan is effective as of August 5, 2015. Unless earlier terminated by the Board and subject to any extension that may be approved by
stockholders, this Plan shall terminate at the close of business on August 4, 2025. After the termination of this Plan either upon such stated expiration date or its earlier termination by the Board, no additional awards may be granted under
this Plan, but previously granted awards (and the authority of the Administrator with respect thereto, including the authority to amend such awards) shall remain outstanding in accordance with their applicable terms and conditions and the terms and
conditions of this Plan. 
 8.6.2    Board Authorization.  The Board may, at any time,
terminate or, from time to time, amend, modify or suspend this Plan, in whole or in part. No awards may be granted during any period that the Board suspends this Plan. 

  
 21 

 8.6.3    Stockholder Approval.  An amendment to
this Plan shall be subject to stockholder approval only to the extent then required by applicable law or stock exchange rules or deemed necessary or advisable by the Board. 

8.6.4    Amendments to Awards.  Without limiting any other express authority of the
Administrator under (but subject to) the express limits of this Plan, the Administrator by agreement or resolution may waive conditions of or limitations on awards to participants that the Administrator in the prior exercise of its discretion has
imposed, without the consent of a participant, and (subject to the requirements of Sections 3.2 and 8.6.5) may make other changes to the terms and conditions of awards. Any amendment or other action that would constitute a repricing of an award is
subject to the limitations set forth in Section 3.2. 
 8.6.5    Limitations on Amendments to Plan and
Awards.  No amendment, suspension or termination of this Plan or change of or affecting any outstanding award agreement shall, without written consent of the participant, affect in any manner materially adverse to the participant any
rights or benefits of the participant or obligations of the Corporation under any award granted under this Plan prior to the effective date of such change. Changes, settlements and other actions contemplated by Section 7 shall not be deemed to
constitute changes or amendments for purposes of this Section 8.6 and shall not require stockholder approval or the consent of the award holder. 
  

	 	8.7	Privileges of Stock Ownership.  Except as otherwise expressly authorized by the Administrator or this Plan, a participant shall not be entitled to any privilege of stock ownership as to any
shares of Common Stock not actually delivered to and held of record by the participant. Except expressly required by Section 7.1 or otherwise expressly provided by the Administrator, no adjustment will be made for dividends or other rights as a
stockholder for which a record date is prior to such date of delivery. 

  

	 	8.8	Governing Law; Construction; Severability. 

8.8.1    Choice of Law.  This Plan, the awards, all documents evidencing awards and all other
related documents shall be governed by, and construed in accordance with the laws of the State of Delaware, notwithstanding any Delaware or other conflict of law provision to the contrary. 

8.8.2    Severability.  If a court of competent jurisdiction holds any provision invalid and
unenforceable, the remaining provisions of this Plan shall continue in effect. 
 8.8.3    Plan
Construction.  It is intended that this Plan, as well as awards granted under this Plan, comply with, and not result in any tax, penalty or interest under, Section 409A of the Code. This Plan, as well as awards granted under this
Plan, shall be construed and interpreted accordingly. 
  

	 	8.9	Captions.  Captions and headings are given to the sections and subsections of this Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or
relevant to the construction or interpretation of this Plan or any provision thereof. 

  
 22 

	 	8.10	Stock-Based Awards in Substitution for Stock Options or Awards Granted by Other Corporation.  Awards may be granted to Eligible Persons in substitution for or in connection with an assumption
of employee stock options, SARs, restricted stock or other stock-based awards granted by other entities to persons who are or who will become Eligible Persons in respect of the Corporation or one of its Subsidiaries, in connection with a
distribution, merger or other reorganization by or with the granting entity or an affiliated entity, or the acquisition by the Corporation or one of its Subsidiaries, directly or indirectly, of all or a substantial part of the stock or assets of the
employing entity. The awards so granted need not comply with other specific terms of this Plan, provided that the awards reflect adjustments giving effect to the assumption or substitution consistent with the conversion applicable to the Common
Stock (or the securities otherwise subject to the award) in the transaction and any change in the issuer of the security. Any shares that are delivered and any awards that are granted by, or become obligations of, the Corporation, as a result of the
assumption by the Corporation of, or in substitution for, outstanding awards previously granted by an acquired company (or previously granted by a predecessor employer (or direct or indirect parent thereof) in the case of persons that become
employed by the Corporation or one of its Subsidiaries in connection with a business or asset acquisition or similar transaction) shall not be counted against the Share Limit or other limits on the number of shares available for issuance under this
Plan. 

  

	 	8.11	Non-Exclusivity of Plan.  Nothing in this Plan shall limit or be deemed to limit the authority of the Board or the Administrator to grant awards or authorize any other compensation, with or
without reference to the Common Stock, under any other plan or authority. 

  

	 	8.12	No Corporate Action Restriction.  The existence of this Plan, the award agreements and the awards granted hereunder shall not limit, affect or restrict in any way the right or power of the
Corporation or any Subsidiary (or any of their respective shareholders, board of directors or committees thereof, as the case may be) to make or authorize: (a) any adjustment, recapitalization, reorganization or other change in the capital
structure or business of the Corporation or any Subsidiary, (b) any merger, amalgamation, consolidation or change in the ownership of the Corporation or any Subsidiary, (c) any issue of bonds, debentures, capital, preferred or prior
preference stock ahead of or affecting the capital stock (or the rights thereof) of the Corporation or any Subsidiary, (d) any dissolution or liquidation of the Corporation or any Subsidiary, (e) any sale or transfer of all or any part of
the assets or business of the Corporation or any Subsidiary, (f) any other award, grant, or payment of incentives or other compensation under any other plan or authority (or any other action with respect to any benefit, incentive or
compensation), or (g) any other corporate act or proceeding by the Corporation or any Subsidiary. No participant, beneficiary or any other person shall have any claim under any award or award agreement against any member of the Board or the
Administrator, or the Corporation or any employees, officers or agents of the Corporation or any Subsidiary, as a result of any such action.

otherwise provides or authorizes in writing. Awards under this Plan may be made in addition to, in combination with, as alternatives to or in payment of grants, awards or commitments under any other plans, arrangements or authority of the

the Code or any successor thereto. 
 2.         Purpose of the Plan.

for the purposes of the Plan unless the Plan shall have been terminated, but all shares sold under the Plan, regardless of source, shall be counted against the limitation set forth above. 

(b)       From time to time and without shareholder approval, the Committee may fix a maximum limit on the
number of shares that may be acquired by any individual during an Exercise Period under the Plan, which limit shall be effective no earlier than the first Offering Period that commences after the determination of such limit by the Committee;
provided, however, that any adjustment to such limit pursuant to Section 15 shall apply to any Exercise Period in progress at the time such adjustment is made. 

4.         Administration of the Plan. 

(a)       The Plan shall be administered by a Committee appointed by, and which shall serve at the pleasure
of, the Board. The Committee shall consist of two or more directors, each of whom is a “Non-Employee Director” within the meaning of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, as such rule may be amended
from time to time. The Committee shall have authority to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan, and to make all other determinations necessary or advisable for the administration of the Plan,
all of which actions and determinations shall be final, conclusive and binding on all persons. 

(b)       The Committee may request advice or assistance or employ such other persons as it in its absolute
discretion deems necessary or appropriate for the proper administration of the Plan, including, but not limited to employing a brokerage firm, bank or other financial institution to assist in the purchase of shares, delivery of reports or other
administrative aspects of the Plan.

liability insurance coverage that may be in effect from time to time. 

  
 4 

 5.         Eligibility to Participate in the
Plan. 
 Subject to limitations imposed by Section 423(b) of the Code, any Eligible Employee who is employed by the Company or a
Participating Subsidiary on an Enrollment Date shall be eligible to participate in the Plan for the Offering Period beginning on that Enrollment Date. 

6.         Offering Periods. 

During the term of the Plan, the Company will grant options to purchase shares of Common Stock in each Offering Period to all Participants in
that Offering Period. The Committee shall determine from time to time, subject to the requirements of Section 423 of the Code, when Offering Periods will be offered during the term of the Plan and shall establish the Enrollment Date(s), the
number and duration of the Exercise Period(s), and the Exercise Date(s) for each such Offering Period, which determinations shall be effective no earlier than the first Offering Period that commences after they are made by the Committee and
provided, however, that no Offering Period may exceed twenty-four (24) months in duration. To the extent consistent with Section 423 of the Code, the Committee may provide for a new Offering Period to commence prior to the termination of
one or more preceding Offering Periods. 
 7.         Election to Participate in the
Plan. 
 (a)       Each Eligible Employee may elect to participate in an Offering Period by
completing an enrollment agreement on a form approved by and in a manner prescribed by the Committee (or its delegate) or, if the Committee does not require enrollment forms, by otherwise completing such enrollment procedures as the Committee may
prescribe. Such agreement must be filed with the Company or such other procedures must be completed, as applicable, prior to the applicable Enrollment Date, unless the Committee establishes an earlier deadline for filing the enrollment form for all
Eligible Employees with respect to a given Offering Period. An Eligible Employee may participate in an Offering Period only if, as of the Enrollment Date of such Offering Period, such Eligible Employee is not participating in any prior Offering
Period which is continuing at the time of such proposed enrollment. 
 (b)       Payroll deductions for a
Participant shall commence on the first payroll date on or following the Enrollment Date and shall end on the last payroll date in the Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided
in Section 12. 
 (c)       Unless a Participant elects otherwise prior to the Enrollment Date of
the immediately succeeding Offering Period, an Eligible Employee who is participating in an Offering Period as of the last Exercise Date of such Offering Period (the “Prior Offering Period”) shall be deemed (i) to have elected to
participate in the immediately succeeding Offering Period and (ii) to have authorized the same payroll deduction for such immediately succeeding Offering Period as was in effect for such Participant immediately prior to the expiration or
termination of the Prior Offering Period. 

  
 5 

 (d)       In its discretion, the Committee may determine (with
such determination to be effective no earlier than the first Offering Period that commences after such determination by the Committee) that the participation of all Participants on an Exercise Date in an Offering Period that includes more than one
Exercise Period shall terminate and such Participants shall be enrolled in a new Offering Period commencing immediately following such Exercise Date if, during such Offering Period, the Fair Market Value determined as of such Exercise Date within
such Offering Period is lower than the Fair Market Value determined as of the Enrollment Date of such Offering Period. In such event, each of such Participants shall be deemed for purposes of this Plan (i) to have elected to participate in such
new Offering Period, and (ii) to have authorized the same payroll deduction for such new Offering Period as was in effect for such Participant immediately prior to the termination of the prior Offering Period. 

8.         Payroll Deductions. 

(a)       All Participant contributions to the Plan shall be made only by payroll deductions. At the time a
Participant files the enrollment agreement with respect to an Offering Period, the Participant shall authorize payroll deductions to be made on each payroll date during the Offering Period in an amount up to 10% (or such other limit as the Committee
may establish prior to the start of the applicable Offering Period) of the Eligible Compensation which the Participant receives on each payroll date during such Offering Period. The Committee also may prescribe other limits, rules or procedures for
payroll deductions. Unless otherwise provided by the Committee, the amount of such payroll deductions shall be a whole percentage (i.e., 1%, 2%, 3%, etc.) of the Participant’s Eligible Compensation. 

(b)       All payroll deductions made for a Participant shall be deposited in the Company’s general
corporate account and shall be credited to the Participant’s account under the Plan. No interest shall accrue or be credited with respect to the payroll deductions of a Participant under the Plan. A Participant may not make any additional
payments into such account. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. 

(c)       A Participant may discontinue participation in the Plan as provided in Section 12. Unless
otherwise provided by the Committee in advance of an Offering Period, a Participant may at any time during the Offering Period (but no more than four times in any calendar year) reduce or increase (subject to the limitations of Section 8(a)
above) the rate of his or her payroll deductions by completing and filing with the Company a change notice in the form provided by the Company. Any such reduction in the rate of a Participant’s payroll deductions shall be effective as of the
pay period specified by the Participant in the Participant’s change notice, but in no event sooner than the first pay period ending more than fifteen (15) days after the Participant files the change notice with the Company. Any such
increase in the rate of a Participant’s payroll deductions shall be effective as of the first date of the next Exercise Period within such Offering Period (or, if such election is made in the final Exercise Period of such Offering Period, the
Enrollment Date of the next Offering Period). 

  
 6 

 9.         Grant of Options. 

(a)       On the Enrollment Date of each Offering Period, subject to the limitations set forth in
Sections 3, 9(b) and 17 hereof, each Participant shall be granted an option to purchase on each Exercise Date during such Offering Period up to a number of shares of the Common Stock determined by dividing such Participant’s payroll
deductions accumulated during the Exercise Period ending on such Exercise Date by the Exercise Price for such Exercise Period (determined as provided in Section 10 below), provided that the number of shares subject to the option shall not
exceed five (5) times the number of shares determined by dividing (i) $40,000 by (ii) the Fair Market Value of a share of the Common Stock on the Enrollment Date multiplied by the percentage (not less than 85%) used to calculate the
Exercise Price for that Offering Period. 
 (b)       Notwithstanding any provision of the Plan to the
contrary, no Participant shall be granted an option under the Plan (i) if, immediately after the grant, such Participant (or any other person whose stock would be attributed to such Participant pursuant to Section 424(d) of the Code) would
own stock and/or hold outstanding options to purchase stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any Parent or any Subsidiary of the Company, or (ii) which permits such
Participant’s rights to purchase stock under all employee stock purchase plans of the Company, its Subsidiaries and any Parent to accrue at a rate which exceeds $25,000 of fair market value of such stock (determined at the time such option is
granted, before giving effect to any discounted purchase price under any such plan) for each calendar year in which such option is outstanding at any time. For purposes of the foregoing clause (ii), a right to purchase stock accrues when it first
becomes exercisable during the calendar year. 
 10.       Exercise Price. 

The Committee shall establish from time to time the method for determining the Exercise Price for each Offering Period under the Plan in
accordance with this Section 10, which determination shall be effective no earlier than the first Offering Period that commences after such determination is made by the Committee. In making its determination, the Committee may provide that the
Exercise Price for an Offering Period shall be determined by applying a discount amount (not to exceed 15%) to either (1) the Fair Market Value of a share of Common Stock on the Enrollment Date of such Offering Period, or (2) the Fair
Market Value of a share of Common Stock on the applicable Exercise Date, or (3) the lesser of the Fair Market Value of a share on the Enrollment Date of such Offering Period or the Fair Market Value of a share on the applicable Exercise
Date. Notwithstanding anything to the contrary in the preceding provisions of this Section 10, in no event shall the Exercise Price per share be less than the par value of a share of Common Stock. 

11.       Exercise of Options. 

Unless a Participant withdraws from the Plan as provided in Section 12, the Participant’s option for the purchase of shares will be
exercised automatically on each Exercise Date of the Offering Period, and the maximum number of full shares subject to option will be purchased for the Participant at the applicable Exercise Price with the accumulated payroll deductions in the
Participant’s account. Any amount remaining in the Participant’s account after an Exercise Date that is not sufficient to purchase a whole share shall be held in the account until the next Exercise Date. In the event that an Exercise
Period has been over-subscribed or that any other applicable Plan limit has been exceeded by a Participant in an Exercise Period, any amount remaining in such Participant’s account shall be refunded to the Participant as soon as
administratively practicable after the end of the Exercise Period. 

  
 7 

 12.       Withdrawal; Termination of Employment. 

(a)       A Participant may withdraw all but not less than all of the payroll deductions credited to the
Participant’s account under the Plan at any time by giving written notice to the Company. All of the Participant’s payroll deductions credited to the Participant’s account will be paid to him or her promptly after receipt of the
Participant’s notice of withdrawal, the Participant’s participation in the Plan will be automatically terminated, and no further payroll deductions for the purchase of shares will be made. Payroll deductions will not resume on behalf of a
Participant who has withdrawn from the Plan unless written notice is delivered to the Company within the open enrollment period preceding the commencement of an Exercise Period directing the Company to resume payroll deductions. 

(b)       Upon termination of the Participant’s Continuous Employment during an Exercise Period for
any reason, including retirement or death, the payroll deductions credited to the Participant’s account for that Exercise Period will be returned to the Participant or, in the case of death, to the Participant’s estate, and the
Participant’s options to purchase shares under the Plan will be automatically terminated as of the date of such termination of Continuous Employment. 

(c)       In the event a Participant fails to maintain Continuous Employment for at least twenty
(20) hours per week during an Offering Period, the Participant will be deemed to have elected to withdraw from the Plan, the payroll deductions credited to the Participant’s account will be returned to the Participant, and the
Participant’s options to purchase shares under the Plan will be terminated. 
 (d)       A
Participant’s withdrawal from an Offering Period will not have any effect upon the Participant’s eligibility to participate in a succeeding Offering Period or in any similar plan which may hereafter be adopted by the Company. 

13.       Transferability. 

Neither payroll deductions credited to a Participant’s account nor options to purchase Common Stock granted under the Plan may be
transferred, assigned, pledged or otherwise disposed of by a Participant other than by will or the laws of descent and distribution. Options granted under the Plan are exercisable during a Participant’s lifetime only by the Participant. 

14.       Reports. 

Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to Participants promptly
following each Exercise Date, which statements will set forth the amounts of payroll deductions, the per share purchase price, the number of shares purchased and the remaining cash balance, if any. 

  
 8 

 15.       Adjustments Upon Changes in Capitalization.

 (a)       If the outstanding shares of Common Stock are increased or decreased, or are changed into or
are exchanged for a different number or kind of shares, as a result of one or more reorganizations, restructurings, recapitalizations, reclassifications, stock splits, reverse stock splits, stock dividends or any similar unusual or extraordinary
corporate transaction, appropriate adjustment shall be made in the number and/or kind of shares, and the Exercise Price thereof, which may be issued in the aggregate and to any Participant upon exercise of options granted under the Plan. 

(b)       In the event of the proposed dissolution or liquidation of the Company, each Offering Period then
in progress will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Committee. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the
Company with or into another corporation or entity, or any other corporate transaction that the Company does not survive (or does not survive as a publicly-traded company in respect of its Common Stock), then, unless the Committee provides that each
option under the Plan shall be assumed or an equivalent option shall be substituted by such successor corporation or entity or a parent or subsidiary of such successor corporation or entity, each Exercise Period then in progress shall be shortened
and a new Exercise Date shall be set by the Committee to occur upon or immediately prior to such transaction or event (the “New Exercise Date”), as of which date the Plan and any Exercise Period and related Offering Period then in
progress will terminate. The New Exercise Date shall be on or before the date of consummation of the transaction and the Committee shall notify each participant in writing, at least ten (10) days prior to the New Exercise Date, that the
Exercise Date for his or her option has been changed to the New Exercise Date and that his or her option will be exercised automatically on the New Exercise Date, unless prior to such date he or she has withdrawn from the Offering Period as provided
in Section 12. The Exercise Price on the New Exercise Date shall be determined as provided in Section 10 hereof, and for purposes of determining such Exercise Price, the New Exercise Date shall be treated as the “Exercise Date.”

 (c)       In all cases, the Committee shall have full discretion to exercise any of the powers and
authority provided under this Section 15, and the Committee’s actions hereunder shall be final and binding on all Participants. No fractional shares of stock shall be issued under the Plan pursuant to any adjustment authorized under the
provisions of this Section 15. 
 16.       Amendment of the Plan. 

The Board may at any time, or from time to time, amend or suspend the Plan, in whole or in part and without notice. Shareholder approval for
any amendment shall not be required, except to the extent required by law or applicable stock exchange rules, or required under Section 423 of the Code in order to preserve the intended tax consequences of the Plan No options may be granted
during any suspension of the Plan or after a termination of the Plan pursuant to Section 17(b) below, but the Committee will retain jurisdiction as to options then outstanding in accordance with the terms of the Plan. No amendment, suspension
or termination pursuant to this Section 16 or Section 17 shall, without written consent of the Participant, affect in any manner materially adverse to the Participant any right or benefits of such Participant or obligations of the Company
under any option granted under the Plan prior to the effective date of such change; provided that the Board may amend, suspend or terminate the Plan as to any outstanding options granted under the Plan for an Offering Period, effective as of any
Exercise Date within that Offering Period, without the consent of the Participants to whom such options were granted. In no event shall changes contemplated by Section 7(d) or Section 15 be deemed to constitute changes or amendments
requiring Participant consent. 

  
 9 

 17.       Termination of the Plan. 

The Plan and all rights of Employees hereunder shall terminate: 

(a)       on the Exercise Date that Participants would become entitled to purchase a number of shares
greater than the number of reserved shares remaining available for purchase under the Plan if the final sentence in this Section 17 were not applied; or 

(b)       at any time, at the discretion of the Board. 

In the event that the Plan terminates under circumstances described in Section 17(a) above, reserved shares remaining as of the
termination date shall be sold to Participants on a pro rata basis. 
 18.       Notices. 

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

19.       Conditions Upon Issuance of Shares. 

(a)       The Plan, the grant and exercise of options to purchase shares of Common Stock under the Plan,
and the Company’s obligation to sell and deliver shares upon the exercise of options to purchase shares shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or
governmental agency as may, in the opinion of counsel for the Company, be required. 
 (b)       The
Company may make such provisions as it deems appropriate for withholding by the Company pursuant to federal or state income tax laws of such amounts as the Company determines it is required to withhold in connection with the purchase or sale by a
Participant of any Common Stock acquired pursuant to the Plan. The Company may require a Participant to satisfy any relevant tax requirements before authorizing any issuance of Common Stock to such Participant. 

20.       Employees’ Rights. 

(a)       Nothing in the Plan (or in any other document related to the Plan) will confer upon any Eligible
Employee or Participant any right to continue in the employ or other service of the Company or any Subsidiary, constitute any contract or agreement of employment or other service or affect an employee’s status as an employee at will, nor shall
interfere in any way with the right of the Company or any Subsidiary to change such person’s compensation or other benefits or to terminate his or her employment or other service, with or without cause. Nothing contained in this
Section 20(a), however, is intended to adversely affect any express independent right of any such person under a separate employment or service contract. 

  
 10 

 (b)       No Participant or other person will have any right,
title or interest in any fund or in any specific asset (including shares of Common Stock) of the Company or any Subsidiary by reason of any option hereunder. Neither the provisions of the Plan (or of any other document related to the Plan), nor the
creation or adoption of the Plan, nor any action taken pursuant to the provisions of the Plan will create, or be construed to create, a trust of any kind or a fiduciary relationship between the Company or any Subsidiary and any Participant or other
person. To the extent that a Participant or other person acquires a right to receive payment pursuant to the Plan, such right will be no greater than the right of any unsecured general creditor of the Company. 

(c)       A Participant will not be entitled to any privilege of stock ownership as to any shares of Common
Stock not actually delivered to and held of record by the Participant. No adjustment will be made for dividends or other rights as a shareholder for which a record date is prior to such date of delivery. 

21.       Miscellaneous. 

(a)       The Plan, the options granted hereunder and any other documents related to the Plan shall be
governed by, and construed in accordance with, the laws of the State of Delaware. 
 (b)       If any
provision of the Plan shall be held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions of the Plan shall continue in effect. 

(c)       Captions and headings are given to the sections of the Plan solely as a convenience to facilitate
reference. Such captions and headings shall not be deemed in any way material or relevant to the construction of interpretation of the Plan or any provision hereof. 

(d)       The adoption of the Plan shall not affect any other Company or Subsidiary compensation or
incentive plans in effect. Nothing in the Plan will limit or be deemed to limit the authority of the Board or Committee (1) to establish any other forms of incentives or compensation for employees of the Company or any Subsidiary (with or
without reference to the Common Stock), or (2) to grant or assume options (outside the scope of and in addition to those contemplated by the Plan) in connection with any proper corporate purpose; to the extent consistent with any other plan or
authority. Benefits received by a Participant under an option granted pursuant to the Plan shall not be deemed a part of the Participant’s compensation for purposes of the determination of benefits under any other employee welfare or benefit
plans or arrangements, if any, provided by the Company or any Subsidiary, except where the Committee or the Board (or the Board of Directors of the Subsidiary that sponsors such plan or arrangement, as applicable) expressly otherwise provides or
authorizes in writing.

 (e)       The Committee may also adopt rules, procedures or
sub-plans applicable to particular Subsidiaries or locations, which sub-plans may be designed to be outside the scope of Section 423 of the Code and need not comply with the otherwise applicable provisions of the Plan. 

As amended August 6, 2012 and August 5, 2015.
