The Committee shall have no obligation to grant any Eligible Individual an Award or to designate an Eligible Individual as a Participant solely by reason of such Eligible Individual having received a prior Award or having been previously designated as a Participant. The Committee may grant more than one Award to a Participant and may designate an Eligible Individual as a Participant for overlapping periods of time.

5. Shares Subject to the Plan

(a)Plan Limit. Subject to adjustment in accordance with Section 14, the maximum aggregate number of Shares that may be issued for all purposes under the Plan shall be equal to 54,879,291 Shares. Shares issued pursuant to Awards under the Plan may be either authorized and unissued Shares or Shares held by the Company in its treasury, or a combination thereof. All of the Shares subject to the Plan Limit may be issued as Incentive Stock Options.

(b)Rules Applicable to Determining Shares Available for Issuance. The number of Shares remaining available for issuance shall be reduced by the number of Shares subject to outstanding Awards and, for Awards that are not denominated by Shares, by the number of Shares actually delivered upon settlement or payment of the Award. For purposes of determining the number of Shares that remain available for issuance under the Plan, the number of Shares corresponding to Awards under the Plan that are forfeited or cancelled or otherwise expire for any reason without having been exercised or settled or that are settled through the issuance of consideration other than Shares (including, without limitation, cash) shall be added back to the Plan Limit and again be available for the grant of Awards; provided, however, that this provision shall not be applicable with respect to (i) the cancellation of a Stock Appreciation Right granted in tandem with an Option upon the exercise of the Option or (ii) the cancellation of an Option granted in tandem with a Stock Appreciation Right upon the exercise of the Stock Appreciation Right. In addition, (i) the number of Shares that are tendered by a Participant or withheld by the Company to pay the exercise price of an Award or to satisfy the Participant’s tax withholding obligations in connection with the vesting, exercise or settlement of an Award and (ii) shares subject to an Option or Stock Appreciation Right but not issued or delivered as a result of the net settlement of such Option or Stock Appreciation Right shall be added back to the Plan Limit and again be available for the grant of Awards.

(c)Individual Limits. Subject to adjustment under Section 14, special limits shall apply to Shares available for Awards under the Plan to Eligible Individuals other than Nonemployee Directors (to whom the limit set forth in Section 5(d) shall apply). Specifically, no Participant may be granted under the Plan in any fiscal year Awards covering more than 10,000,000 Shares.

(d)Nonemployee Director Limit. Subject to adjustment under Section 14, no Nonemployee Director shall receive regular annual Awards for any fiscal year having a grant date fair value, determined using assumptions and methods that are consistent in all material

respects with the assumptions used to disclose such grants in the Company’s proxy statement for the year to which such grants relate, that exceeds $500,000 or any special or one-time Award upon election or appointment to the Board having a grant date fair value, determined as described above, that exceeds $1,000,000, provided, however, that no Nonemployee Director shall receive Awards for any fiscal year having a grant date fair value that exceeds $1,000,000 in the aggregate.

(e)Substitute Awards. To the extent not prohibited by applicable laws, rules and regulations, any Shares underlying Substitute Awards shall not be counted against the number of Shares remaining for issuance and shall not be subject to Sections 5(c) or (d).

6. Awards in General

(a)Types of Awards. Awards under the Plan may consist of Options, Restricted Shares, Restricted Share Units, Stock Appreciation Rights, Performance Stock, Performance Stock Units and Other Awards. Any Award described in Sections 8 through 12 may be granted singly or in combination or tandem with any other Award, as the Committee may determine. Subject to Section 6(g), Awards under the Plan may be made in combination with, in replacement of, or as alternatives to Awards or rights under any other compensation or benefit plan of the Company, including the plan of any acquired entity.

(b)Vesting and Exercise. The Committee shall set the vesting criteria applicable to an Award, which, depending on the extent to which the criteria are met, will determine the extent to which the Award becomes exercisable or the number of Shares or the amount of cash that will be distributed or paid out to the Participant with respect to the Award. The Committee may set vesting criteria based upon the achievement of Company-wide, business unit, or individual goals (including, but not limited to, continued employment or provision of services), or any other basis determined by the Committee in its discretion.

(c)Terms Set Forth in Award Document. The terms and conditions of each Award shall be set forth in an Award Document in a form approved by the Committee for such Award, which Award Document shall contain terms and conditions not inconsistent with the Plan. Notwithstanding the foregoing, and subject to applicable laws, rules and regulations, the Committee may at any time following grant (i) accelerate the vesting, exercisability, lapse of restrictions, settlement or payment of any Award, (ii) eliminate the restrictions and conditions applicable to an Award or (iii) extend the post‑termination exercise period of an outstanding Award (subject to the limitations of Section 409A). The terms of Awards may vary among Participants, and the Plan does not impose upon the Committee any requirement to make Awards subject to uniform terms. Accordingly, the terms of individual Award Documents may vary.

(d)Termination of Employment. The Committee shall specify at or after the time of grant of an Award the provisions governing the disposition of an Award in the event of a Participant’s termination of employment (including by reason of retirement) with the Company or any of its Affiliates or the Participant’s death or Disability. Subject to applicable laws, rules and regulations, in connection with a Participant’s termination of employment, the Committee shall have the discretion to accelerate the vesting, exercisability or settlement of, eliminate the restrictions or conditions applicable to, or extend the post-termination exercise period of an outstanding Award (subject to the limitations of Section 409A). Such provisions may be specified in the applicable Award Document or determined at a subsequent time.

(e)Dividends and Dividend Equivalents. The Committee may provide Participants with the right to receive dividends or payments equivalent to dividends or interest

with respect to an outstanding Award, which payments can either be paid currently or deemed to have been reinvested in Shares, and can be made in Shares, cash or a combination thereof, as the Committee shall determine; provided, however, that (i) no payments of dividends or dividend equivalents may be made unless and until the related Award is earned and vested and (ii) the terms of any reinvestment of dividends must comply with all applicable laws, rules and regulations, including, without limitation, Section 409A. Notwithstanding the foregoing, no dividends or dividend equivalents shall be paid with respect to Options or Stock Appreciation Rights.

(f)Rights of a Stockholder. A Participant shall have no rights as a stockholder with respect to Shares covered by an Award until the date the Participant or his nominee becomes the holder of record of such Shares. No adjustment shall be made for dividends or other rights for which the record date is prior to such date, except as provided in Section 14.

(g)Performance‑Based Awards.

(i) The Committee may establish Performance Targets and goals based on any Performance Criteria it deems appropriate.

(1) To the extent applicable, the Performance Targets shall be determined in accordance with generally accepted accounting principles (subject to adjustments and modifications for specified types of events or circumstances approved by the Committee in advance) consistently applied on a business unit, divisional, subsidiary or consolidated basis or any combination thereof.

(2) The Performance Targets may be described in terms of objectives that are related to the individual Participant or objectives that are Company‑wide or related to a Subsidiary, business unit, or region and may be measured on an absolute or cumulative basis or on the basis of percentage of improvement over time, and may be measured in terms of Company performance (or performance of the applicable Subsidiary, business unit, or region) or measured relative to selected peer companies or a market index.

(3) The Participants will be designated, and the applicable Performance Targets will be established, by the Committee. Any payment of an Award granted with Performance Targets shall be conditioned on the written certification of the Committee in each case that the Performance Targets and any other material conditions were satisfied.

(h) No Repricing of Options and Stock Appreciation Rights. Except for adjustments pursuant to Section 14, the per Share exercise price of any Option or Stock Appreciation Right may not be decreased after the grant of the Award, and an Option or Stock Appreciation Right whose per share exercise price is greater than the Fair Market Value of a Share on the relevant date of determination may not be surrendered as consideration in exchange for cash (for the sake of clarity, including cash buyouts), the grant of a new Option or Stock Appreciation Right with a lower exercise price per Share or the grant of a stock award, without stockholder approval.

(i) No Discount Options or Stock Appreciation Rights. In no event shall the exercise price per Share of an Option or the grant price per Share of a Stock Appreciation Right

be less than 100% of the Fair Market Value of a Share on the date of grant; provided, however, that the exercise price of a Substitute Award granted as an Option shall be determined in accordance with Section 409A and may be less than 100% of the Fair Market Value.

(j) Term of Options and Stock Appreciation Rights. An Option or Stock Appreciation Right shall be effective for such term as shall be determined by the Committee and as set forth in the Award Document relating to such Award. The Committee may extend the term of an Option or Stock Appreciation Right after the time of grant; provided, however, that the term of an Option or Stock Appreciation Right may in no event extend beyond the tenth (10th) anniversary of the date of grant of such Award.

7. Change in Control

In the event of a Change in Control, the Committee, in its sole discretion, may take such actions, if any, as it deems necessary or desirable with respect to any Award that is outstanding. Such actions may include, without limitation: (a) the acceleration of the vesting, settlement and/or exercisability of an Award; (b) the payment of a cash amount in exchange for the cancellation of an Award; (c) the cancellation of Options and/or Stock Appreciation Rights without the payment of consideration therefor if the exercise price of such Options and/or Stock Appreciation Rights equals or exceeds the price paid for a Share in connection with the Change in Control; and/or (d) the issuance of substitute Awards that substantially preserve the value, rights and benefits of any affected Awards.

8. Terms and Conditions of Options

(a)General. The Committee, in its discretion, may grant Options to Eligible Individuals and shall determine whether such Options shall be Incentive Stock Options or Nonqualified Stock Options. Each Option shall be evidenced by an Award Document that shall expressly identify the Option as an Incentive Stock Option or Nonqualified Stock Option, and be in such form and contain such provisions as the Committee shall from time to time deem appropriate.

(b)Payment of Exercise Price. Subject to the provisions of the applicable Award Document and Company policy in effect from time to time, the exercise price of an Option may be paid: (i) in cash or cash equivalents; (ii) by actual delivery or attestation to ownership of freely transferable Shares already owned by the person exercising the Option; (iii) by a combination of cash and Shares equal in value to the exercise price; (iv) through net share settlement or similar procedure involving the withholding of Shares subject to the Option with a value equal to the exercise price; or (v) by such other means as the Committee may authorize. In accordance with the rules and procedures authorized by the Committee for this purpose, the Option may also be exercised through a “cashless exercise” procedure authorized by the Committee from time to time that permits Participants to exercise Options by delivering irrevocable instructions to a broker to deliver promptly to the Company the amount of sale or loan proceeds necessary to pay the exercise price and the amount of any required tax or other withholding obligations or such other procedures determined by the Company from time to time. The Committee may provide that in-the-money Options will be exercised automatically, with no action required on the part of a Participant, using a net share settlement or similar procedure immediately (or shortly) before their scheduled expiration date where Participants are precluded from using other methods of exercise due to legal restrictions or Company policy (including policies on trading in Shares).

(c)Incentive Stock Options. The exercise price per Share of an Incentive Stock Option shall be fixed by the Committee at the time of grant or shall be determined by a

method specified by the Committee at the time of grant, but in no event shall the exercise price of an Option be less than the minimum exercise price specified in Section 6(i). No Incentive Stock Option may be issued to any individual who, at the time the Incentive Stock Option is granted, owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any of its Subsidiaries, unless (i) the exercise price determined as of the date of grant is at least 110% of the Fair Market Value on the date of grant of the Shares subject to such Incentive Stock Option and (ii) the Incentive Stock Option is not exercisable more than five (5) years from the date of grant thereof. No Participant shall be granted any Incentive Stock Option which would result in such Participant receiving a grant of Incentive Stock Options that would have an aggregate Fair Market Value in excess of $100,000, determined as of the time of grant, that would be exercisable for the first time by such Participant during any fiscal year. Any grants in excess of this limit shall be treated as Non-Qualified Stock Options. No Incentive Stock Option may be granted under the Plan after the tenth anniversary of the Effective Date. The terms of any Incentive Stock Option granted under the Plan shall comply in all respects with the provisions of Section 422 of the Code, or any successor provision thereto, as amended from time to time.

(d)Early Exercise of Non-qualified Options. The Committee, in its discretion, may grant Non-Qualified Stock Options that contain an “early exercise” feature, which shall provide a Participant with the right (but not the obligation) to immediately exercise such portion of the Option for Shares that shall be subject to the same vesting schedule as the underlying Option.

9. Terms and Conditions of Restricted Shares and Restricted Share Units

(a)Restricted Shares. The Committee, in its discretion, may grant or sell Restricted Shares to Eligible Individuals. An Award of Restricted Shares shall consist of one or more Shares granted or sold to an Eligible Individual, and shall be subject to the terms, conditions and restrictions set forth in the Plan and established by the Committee in connection with the Award and specified in the applicable Award Document. Restricted Shares may, among other things, be subject to restrictions on transferability, vesting requirements or other specified circumstances under which it may be canceled.

(b)Restricted Share Units. The Committee, in its discretion, may grant Restricted Share Units to Eligible Individuals. A Restricted Share Unit shall entitle a Participant to receive, subject to the terms, conditions and restrictions set forth in the Plan and the applicable Award Document, one or more Shares. Restricted Share Units may, among other things, be subject to restrictions on transferability, vesting requirements or other specified circumstances under which they may be canceled. If, and when, the cancellation provisions lapse, the Restricted Share Units shall be settled by the delivery of Shares or, at the sole discretion of the Committee, cash, or a combination of cash and Shares, with a value equal to the Fair Market Value of the Shares at the time of payment.

10. Stock Appreciation Rights

The Committee, in its discretion, may grant Stock Appreciation Rights to Eligible Individuals. The Committee may grant Stock Appreciation Rights in tandem with Options or as stand-alone Awards. Each Stock Appreciation Right shall be subject to the terms, conditions and restrictions set forth in the Plan and established by the Committee in connection with the Award and specified in the applicable Award Document. A Stock Appreciation Right shall entitle a Participant to receive, upon satisfaction of the conditions to payment specified in the applicable Award Document, an amount equal to the excess, if any, of the Fair Market Value of a

Share on the exercise date of the number of Shares for which the Stock Appreciation Right is exercised over the per Share grant price for such Stock Appreciation Right specified in the applicable Award Document. Payments to a Participant upon exercise of a Stock Appreciation Right may be made in cash or Shares, as determined by the Committee on or following the date of grant. The Committee may provide that in-the-money Stock Appreciation Rights will be exercised automatically, with no action required on the part of a Participant, immediately (or shortly) before their scheduled expiration date where Participants are precluded from otherwise exercising such Stock Appreciation Rights due to legal restrictions or Company policy (including policies on trading in Shares).

11. Terms and Conditions of Performance Stock and Performance Stock Units

The Committee may grant Performance Stock or Performance Stock Units to Eligible Individuals. An Award of Performance Stock or Performance Stock Units shall consist of, or represent a right to receive, a Target Amount of Shares granted to an Eligible Individual based on the achievement of Performance Targets over the applicable Performance Period, and shall be subject to the terms, conditions and restrictions set forth in the Plan and established by the Committee in connection with the Award and specified in the applicable Award Document. Payments to a Participant in settlement of an Award of Performance Stock or Performance Stock Units may be made in cash or Shares, as determined by the Committee on or following the date of grant.

12. Other Awards

The Committee shall have the authority to establish the terms and provisions of other forms of Awards (such terms and provisions to be specified in the applicable Award Document) not described above that the Committee determines to be consistent with the purpose of the Plan and the interests of the Company, which Awards may provide for: (i) payments in the form of cash, Shares, notes or other property as the Committee may determine based in whole or in part on the value or future value of Shares or on any amount that the Company pays as dividends or otherwise distributes with respect to Shares; (ii) the acquisition or future acquisition of Shares; (iii) cash, Shares, notes or other property as the Committee may determine (including payment of dividend equivalents in cash or Shares) based on one or more criteria determined by the Committee unrelated to the value of Shares; or (iv) any combination of the foregoing. Awards pursuant to this Section 12 may, among other things, be made subject to restrictions on transfer, vesting requirements or cancellation under specified circumstances.

13. Certain Restrictions

(a)Transfers. A Participant’s rights and interests under the Plan, including any Award previously made to such Participant or any amounts payable under the Plan may not be assigned, pledged, or transferred, except, in the event of the Participant’s death, to a designated beneficiary in accordance with the Plan, or in the absence of such designation, by will or the laws of descent or distribution or, except in the case of an Incentive Stock Option, pursuant to a domestic relations order, as the case may be; provided, however, that the Committee may, subject to applicable laws, rules and regulations and such terms and conditions as it shall specify, permit the transfer of an Award, other than an Incentive Stock Option, for no consideration to a permitted transferee.

(b)Award Exercisable Only by Participant. During the lifetime of a Participant, an Award shall be exercisable only by the Participant or by a permitted transferee to whom such Award has been transferred in accordance with Section 13(a) above. The grant of an Award shall impose no obligation on a Participant to exercise or settle the Award.

(c)Section 83(b) Election. If a Participant makes an election under Section 83(b) of the Code to be taxed with respect to any Award as of the date of transfer of the Award rather than as of the date or dates upon which the Participant would otherwise be taxable under Section 83 of the Code, the Participant shall be required to deliver a copy of such election to the Company promptly after filing such election with the Internal Revenue Service.

14. Recapitalization or Reorganization

(a)Authority of the Company and Stockholders. The existence of the Plan, the Award Documents and the Awards granted hereunder shall not affect or restrict in any way the right or power of the Company or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or business, any merger or consolidation of the Company, any issue of stock or of options, warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks whose rights are superior to or affect the Shares or the rights thereof or which are convertible into or exchangeable for Shares, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

(b)Change in Capitalization. Notwithstanding any provision of the Plan or any Award Document, the number and kind of Shares authorized for issuance under Section 5, including the maximum number of Shares available under the special limits provided for in Section 5(c) and 5(d), shall be equitably adjusted in the manner deemed necessary by the Committee in the event of a stock split, reverse stock split, stock dividend, recapitalization, reorganization, partial or complete liquidation, reclassification, merger, consolidation, separation, extraordinary stock or cash dividend, split‑up, spin‑off, combination, exchange of Shares, warrants or rights offering to purchase Shares at a price substantially below Fair Market Value, or any other corporate event or distribution of stock or property of the Company affecting the Shares in order to preserve, but not increase, the benefits or potential benefits intended to be made available under the Plan. In addition, upon the occurrence of any of the foregoing events, the number and kind of Shares subject to any outstanding Award and the exercise price per Share (or the grant price per Share, as the case may be), if any, under any outstanding Award shall be equitably adjusted in the manner deemed necessary by the Committee (including by payment of cash to a Participant) in order to preserve the benefits or potential benefits intended to be made available to Participants. Any such determinations made by the Committee may be made on an Award-by-Award basis. Unless otherwise determined by the Committee, such adjusted Awards shall be subject to the same restrictions and vesting or settlement schedule to which the underlying Award is subject (subject to the limitations of Section 409A).

15. Term of the Plan

Unless earlier terminated pursuant to Section 16, the Plan shall terminate on the tenth (10th) anniversary of the Effective Date, except with respect to Awards then outstanding. No Awards may be granted under the Plan after the tenth (10th) anniversary of the Effective Date.

16. Amendment and Termination

Subject to applicable laws, rules and regulations, the Board may at any time terminate or, from time to time, amend, modify or suspend the Plan; provided, however, that no termination, amendment, modification or suspension (i) will be effective without the approval of the stockholders of the Company if such approval is required under applicable laws, rules and regulations, including the rules of the NYSE and such other securities exchanges, if any, as may

be designated by the Board from time to time, and (ii) shall materially and adversely alter or impair the rights of a Participant in any Award previously made under the Plan without the consent of the holder thereof. Notwithstanding the foregoing, the Board shall have broad authority to amend the Plan or any Award under the Plan without the consent of a Participant to the extent it deems necessary or desirable, including:

(a)to comply with, or take into account changes in, or interpretations of, applicable tax laws, securities laws, employment laws, accounting rules and other applicable laws, rules and regulations, including without limitation;

(b)to avoid, in the reasonable, good faith judgment of the Company, the imposition on any Participant of any tax, interest or penalty under Section 409A; or

(c)to take into account unusual or nonrecurring events or market conditions (including, without limitation, the events described in Section 14(b)).

17. Miscellaneous

(a)Compliance with Legal Requirements. The Plan and the granting of Awards shall be subject to all applicable federal and state laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may be required.

(b)Tax Withholding. The Company or an Affiliate, as appropriate, may require any individual entitled to receive a payment of an Award to remit to the Company, prior to payment, an amount sufficient to satisfy any applicable tax required or permitted to be withheld (up to the maximum statutory tax rate in the relevant jurisdiction). In the case of an Award payable in Shares, the Company or an Affiliate, as appropriate, may permit or require a Participant to satisfy, in whole or in part, such obligation to remit taxes by directing the Company to withhold shares that would otherwise be received by such individual or to repurchase shares that were issued to the Participant to satisfy the minimum statutory withholding rates for any applicable tax withholding purposes, in accordance with all applicable laws and pursuant to such rules as the Committee may establish from time to time. The Company or an Affiliate, as appropriate, shall also have the right to deduct from all cash payments made to a Participant (whether or not such payment is made in connection with an Award) any applicable taxes required or permitted to be withheld (up to the maximum statutory tax rate in the relevant jurisdiction) with respect to such payments.

(c)No Right to Awards or Employment. No person shall have any claim or right to receive Awards under the Plan. Neither the Plan, the grant of Awards under the Plan nor any action taken or omitted to be taken under the Plan shall be deemed to create or confer on any Eligible Individual any right to be retained in the employ of the Company or any of its Affiliates, or to interfere with or to limit in any way the right of the Company or any of its Affiliates to terminate the employment of such Eligible Individual at any time. No Award shall constitute salary, recurrent compensation or contractual compensation for the year of grant, any later year or any other period of time. Payments received by a Participant under any Award made pursuant to the Plan shall not be included in, nor have any effect on, the determination of employment‑related rights or benefits under any other employee benefit plan or similar arrangement provided by the Company and its Affiliates, unless otherwise specifically provided for under the terms of such plan or arrangement or by the Committee.

(d)Securities Law Restrictions. An Award may not be exercised or settled, and no Shares may be issued in connection with an Award, unless the issuance of such shares (i) has been registered under the Securities Act of 1933, as amended, (ii) has qualified under

applicable state “blue sky” laws (or the Company has determined that an exemption from registration and from qualification under such state “blue sky” laws is available) and (iii) complies with all applicable securities laws. The Committee may require each Participant purchasing or acquiring Shares pursuant to an Award under the Plan to represent to and agree with the Company in writing that such Eligible Individual is acquiring the Shares for investment purposes and not with a view to the distribution thereof. All certificates for Shares delivered under the Plan shall be subject to such stock‑transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of the Securities and Exchange Commission, any exchange upon which the Shares are then listed, and any applicable securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

(e)Section 16 of the Exchange Act. Notwithstanding anything contained in the Plan or any Award Document under the Plan to the contrary, if the consummation of any transaction under the Plan, or the taking of any action by the Committee in connection with a Change in Control of the Company, would result in the possible imposition of liability on a Participant pursuant to Section 16(b) of the Exchange Act, the Committee shall have the right, in its discretion, but shall not be obligated, to defer such transaction or the effectiveness of such action to the extent necessary to avoid such liability, but in no event for a period longer than 180 days.

(f)Section 409A. To the extent that the Committee determines that any Award granted under the Plan is subject to Section 409A, the Award Document evidencing such Award shall incorporate the terms and conditions required by Section 409A. To the extent applicable, the Plan and Award Documents shall be interpreted in accordance with Section 409A and interpretive guidance issued thereunder. Notwithstanding any contrary provision in the Plan or an Award Document, if the Committee determines that any provision of the Plan or an Award Document contravenes any regulations or guidance promulgated under Section 409A or would cause an Award to be subject to additional taxes, accelerated taxation, interest and/or penalties under Section 409A, the Committee may modify or amend such provision of the Plan or Award Document without consent of the Participant in any manner the Committee deems reasonable or necessary. In making such modifications the Committee shall attempt, but shall not be obligated, to maintain, to the maximum extent practicable, the original intent of the applicable provision without contravening the provisions of Section 409A. Moreover, any discretionary authority that the Committee may have pursuant to the Plan shall not be applicable to an Award that is subject to Section 409A to the extent such discretionary authority would contravene Section 409A.

(g)Awards to Individuals Subject to Laws of a Jurisdiction Outside of the United States. To the extent that Awards under the Plan are awarded to Eligible Individuals who are domiciled or resident outside of the United States or to persons who are domiciled or resident in the United States but who are subject to the tax laws of a jurisdiction outside of the United States, the Committee may adjust the terms of the Awards granted hereunder to such person (i) to comply with the laws, rules and regulations of such jurisdiction and (ii) to permit the grant of the Award not to be a taxable event to the Participant. The authority granted under the previous sentence shall include the discretion for the Committee to adopt, on behalf of the Company, one or more sub‑plans applicable to separate classes of Eligible Individuals who are subject to the laws of jurisdictions outside of the United States.

(h)References to Termination of Employment. References to “termination of employment” shall also mean termination of any other service relationship of the Participant with the Company or any of its Subsidiaries, as applicable.

(i)No Limitation on Corporate Actions. Nothing contained in the Plan shall be construed to prevent the Company or any Affiliate from taking any corporate action, whether or not such action would have an adverse effect on any Awards made under the Plan. No Participant, beneficiary or other person shall have any claim against the Company or any Affiliate as a result of any such action.

(j)Unfunded Plan. Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between the Company and any Participant, beneficiary or legal representative or any other person. To the extent that a person acquires a right to receive payments under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company. All payments to be made hereunder shall be paid from the general funds of the Company and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in the Plan. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974, as amended.

(k)Application of Funds. The proceeds received by the Company from the sale of Shares pursuant to Awards will be used for general corporate purposes.

(l)Satisfaction of Obligations. Subject to applicable laws, rules and regulations, the Company may apply any cash, Shares, securities or other consideration received upon exercise of settlement of an Award to any obligations a Participant owes to the Company and its Affiliates in connection with the Plan or otherwise.

(m)Award Document. In the event of any conflict or inconsistency between the Plan and any Award Document, the Plan shall govern and the Award Document shall be interpreted to minimize or eliminate any such conflict or inconsistency.

(n)Successors. All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

(o)Headings. The headings of Sections herein are included solely for convenience of reference and shall not affect the meaning of any of the provisions of the Plan.

(p)Clawback. Notwithstanding anything in the Plan to the contrary, all Awards granted under the Plan, any payments made pursuant to the Plan and any gains realized upon exercise or settlement of an Award shall be subject to clawback or recoupment, as permitted or mandated by applicable law, rules, regulations or any Company policy as enacted, adopted or modified from time to time.

(q)Severability. If any provision of this Plan is held unenforceable, the remainder of the Plan shall continue in full force and effect without regard to such unenforceable provision and shall be applied as though the unenforceable provision were not contained in the Plan.

(r)Governing Law. Except as to matters of federal law, the Plan and all actions taken thereunder shall be governed by and construed in accordance with the laws of the State of Delaware (other than its conflict of law rules).
