(i)The Committee may act only by a majority of its members then in office, except that the Committee may, except to the extent prohibited by applicable law or the listing standards of the Applicable Exchange and subject to Section 122, allocate all or any portion of its responsibilities and powers to any one or more of its members and may delegate all or any part of its responsibilities and powers to any person or persons selected by it. Any such allocation or delegation may be revoked by the Committee at any time.

(c)Discretion of Committee. Subject to the last sentence of the definition of “Cause,” any determination made by the Committee or pursuant to delegated authority under the provisions of the Plan with respect to any Award shall be made in the sole discretion of the Committee or such delegate at the time of the grant of the Award or, unless in contravention of any express term of the Plan, at any time thereafter.

The effectiveness of an Award shall be subject to the Award Agreement’s being signed by the Company and the Participant receiving the Award unless otherwise provided in the Award Agreement.

Section 3.Common Stock Subject to Plan

(a)Plan Maximums. Subject to adjustment as provided in Section 3(g), the total number of Shares reserved and authorized for Awards granted under the Plan, all of which may be granted as Incentive Stock Options, shall be equal to 1,525,000 less the total number of Shares that are subject to an any award granted after December 31, 2022 and prior to the Effective Date under the Prior Plans. Any Shares that are subject to an Award shall be counted against this limit as one Share for every one Share granted. After the Effective Date, no awards may be granted under the Prior Plans, it being understood that (A) awards outstanding under the Prior Plans as of the Effective Date shall remain in full force and effect under the Prior Plans according to their respective terms and (B) dividend equivalents may continue to be issued under the Prior Plans in respect of such awards.

(b)Rules for Calculating Shares Issued. If (i) any Shares subject to an Award are forfeited or an Award expires or is settled for cash (in whole or in part), or (ii) on or after the Effective Date, any Shares subject to an award under the Prior Plans are forfeited or an award under the Prior Plans expires or is settled for cash (in whole or in part), then, in each such case, the Shares subject to such Award under the Plan or award under the Prior Plans shall, to the extent of such forfeiture, expiration or cash settlement, be added to the Shares available for Awards under the Plan, in accordance with Section 3(d). If withholding tax liabilities arising from an Award other than a Stock Option, Stock Appreciation Right or Cash Award or on or after the Effective Date, from an award other than an option or stock appreciation right under the Prior Plans are satisfied by the tendering of Shares (either actually or by attestation) or by the withholding of Shares by the Company in accordance with Section 15(d), all the Shares so tendered or withheld shall be added to the Shares available for Awards under the Plan in accordance with Section 3(d). Notwithstanding anything to the contrary contained herein, the following Shares shall not be added to the Shares authorized for grant under Section 3(a): (A) Shares tendered by a Participant or withheld by the Company in payment of the exercise price of Stock Options under the Plan or options under the Prior Plans, (B) Shares tendered by a Participant or withheld by the Company to satisfy any tax withholding obligation with respect to Stock Options or Stock Appreciation Rights under the Plan or options or stock appreciation rights under the Prior Plans, and (C) Shares subject to a Stock Appreciation Right under the Plan or a stock appreciation right under the Prior Plan that are not issued in connection with its stock settlement on exercise thereof.

(c)Substitute Awards. Substitute Awards shall not reduce the Shares authorized for grant under the Plan, nor shall Shares subject to a Substitute Award be added to the Shares available for Awards under the Plan as provided in Section 3(b). In addition, if a Person acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a preexisting plan approved by shareholders of such

Person and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such preexisting plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not be added to the Shares available for Awards under the Plan as provided in Section 3(b)); provided that Awards using such available Shares shall not be made after the date awards or grants were permitted to be made under the terms of the preexisting plan, absent the acquisition or combination, and shall only be made to individuals who were not employees or non-employee directors of the Company or any of its Subsidiaries prior to such acquisition or combination.

(d)Recycling of Shares. Any Shares that again become available for Awards under the Plan pursuant to this Section 3 shall be added as one Share for every one Share subject to Awards granted under the Plan or awards granted under the Prior Plans.

(e)Character of Shares. Any Shares issued hereunder may consist, in whole or in part, of authorized and unissued Shares, treasury Shares or Shares purchased in the open market or otherwise.

(f)Limits on Director Compensations. Notwithstanding any other provision of the Plan to the contrary, the aggregate value of the total compensation made to any non-employee director of the Company during any Board Cycle shall not exceed $750,000; provided, however, that the limitation of this Section 3(f) shall be $1,250,000 in the first Board Cycle in which an individual becomes a member of the Board. For purposes of this limit, a non-employee director’s total compensation includes any Awards granted under the Plan and any other compensation (such as cash retainers or fees) for director services. Any Award granted or compensation made to a Participant in lieu of his or her services as an employee or a consultant (other than a non-employee director) will not count for this limitation.

(g)Adjustment Provisions.

(i)In the event of a merger, consolidation, acquisition of property or shares, stock rights offering, liquidation, disposition for consideration of the Company’s direct or indirect ownership of a Subsidiary or Affiliate (including by reason of a Disaffiliation), or similar event affecting the Company or any of its Subsidiaries (each, a “Corporate Transaction”), the

Committee or the Board may in its discretion make such substitutions or adjustments as it deems appropriate and equitable to (A) the aggregate number and kind of Shares or other securities reserved for issuance and delivery under the Plan, (B) the maximum limitations set forth in Section 3(a), (C) the number and kind of Shares or other securities subject to outstanding Awards, (D) the Performance Goals applicable to outstanding Awards and (E) the exercise price of outstanding Awards.

(ii)In the event of a stock dividend, stock split, reverse stock split, reorganization, share combination, recapitalization or similar event affecting the capital structure of the Company, or a Disaffiliation, separation or spinoff, in each case without consideration, or other extraordinary dividend of cash or other property to the Company’s shareholders, the Committee or the Board shall make such substitutions or adjustments as it deems appropriate and equitable to (A) the aggregate number and kind of Shares or other securities reserved for issuance and delivery under the Plan, (B) the maximum limitations set forth in Section 3(a), (C) the number and kind of Shares or other securities subject to outstanding Awards, (D) the Performance Goals applicable to outstanding Awards and (E) the exercise price of outstanding Awards.

(iii)In the case of Corporate Transactions, such adjustments may include, without limitation, (A) the cancellation of outstanding Awards in exchange for payments of cash, property or a combination thereof having an aggregate value equal to the value of such Awards, as determined by the Committee or the Board in its sole discretion (it being understood that in the case of a Corporate Transaction with respect to which shareholders of Common Stock receive consideration other than publicly traded equity securities of the ultimate surviving entity, any such determination by the Committee that the value of a Stock Option or Stock Appreciation Right shall for this purpose be deemed to equal the excess, if any, of the value of the consideration being paid for each Share pursuant to such Corporate Transaction over the exercise price of such Stock Option or Stock Appreciation Right shall conclusively be deemed valid); (B) the substitution of other property (including, without limitation, cash or other securities of the Company and securities of entities other than the Company) for the Shares subject to outstanding Awards; and (C) in connection with any Disaffiliation, arranging for the assumption of Awards, or replacement of Awards with new awards based on other property or other securities (including, without limitation, other securities of the Company and securities of entities other than the Company), by the affected Subsidiary, Affiliate or division or by the entity that controls such Subsidiary, Affiliate or division following such Disaffiliation (as well as any corresponding adjustments to Awards that remain based upon Company securities). The Committee may adjust the Performance Goals applicable to any Awards to reflect any unusual or nonrecurring events and other extraordinary items, impact of charges for restructurings, discontinued operations and the cumulative effects of accounting or tax changes, each as defined by generally accepted accounting principles or as identified in the Company’s financial statements, notes to the

financial statements, management’s discussion and analysis or other Company filings with the Commission.

(iv)(A) Any adjustments made pursuant to this Section 3(g) to Awards that are considered “nonqualified deferred compensation” within the meaning of Section 409A of the Code shall be made in compliance with the requirements of Section 409A of the Code; (B) any adjustments made pursuant to this Section 3(g) to Awards that are not considered “nonqualified deferred compensation” subject to Section 409A of the Code shall be made in such a manner as to ensure that after such adjustments, either (I) the Awards continue not to be subject to Section 409A of the Code or (II) there does not result in the imposition of any penalty taxes under Section 409A of the Code in respect of such Awards.

(v)Any adjustment under this Section 3(g) need not be the same for all Participants.

Section 4.Eligibility

Awards may be granted under the Plan to Eligible Individuals; provided, however, that Incentive Stock Options may be granted only to employees of the Company and its Subsidiaries or parent corporation (within the meaning of Section 424(f) of the Code).

Section 5.Stock Options and Stock Appreciation Rights

(a)Types of Stock Options. Stock Options may be granted alone or in addition to other Awards granted under the Plan and may be of two types: Incentive Stock Options and Nonqualified Stock Options. The Award Agreement for a Stock Option shall indicate whether the Stock Option is intended to be an Incentive Stock Option or a Nonqualified Stock Option.

(b)Nature of Stock Appreciation Rights. Upon the exercise of a Stock Appreciation Right, the Participant shall be entitled to receive an amount in cash, Shares or both, in value equal to the product of (i) the excess of the Fair Market Value of one Share over the exercise price of the applicable Stock Appreciation Right, multiplied by (ii) the number of Shares in respect of which the Stock Appreciation Right has been exercised. The applicable Award Agreement shall specify whether such payment is to be made in cash or Common Stock or both, or shall reserve to the Committee or the Participant the right to make that determination prior to or upon the exercise of the Stock Appreciation Right.

(c)Exercise Price; Prohibition on Repricing and Cash Buyouts. The exercise price per Share subject to a Stock Option or Stock Appreciation Right shall be determined by the Committee and set forth in the applicable Award Agreement, and shall not be less than the Fair Market Value of a share of the Common Stock on the applicable Grant Date. In no event may any Stock Option or Stock Appreciation Right granted under the Plan be amended, other than pursuant to Section 3(g), to decrease the exercise price thereof, be cancelled in exchange for cash or other Awards or in conjunction with the grant of any new Stock Option or Stock Appreciation Right with a lower exercise price, or otherwise be subject to any action that would be treated, under the Applicable Exchange listing standards or for accounting purposes, as a “repricing” of such Stock Option or Stock Appreciation Right, unless such amendment, cancellation, or action is approved by the Company’s shareholders.

(d)Term. The Term of each Stock Option and each Stock Appreciation Right shall be fixed by the Committee, but no Stock Option or Stock Appreciation Right shall be exercisable more than 10 years after its Grant Date.

(e)Exercisability. Except as otherwise provided herein, Stock Options and Stock Appreciation Rights shall be exercisable at such time or times and be subject to such terms and conditions as shall be determined by the Committee.

(f)Method of Exercise. Subject to the provisions of this Section 5, Stock Options and Stock Appreciation Rights may be exercised, in whole or in part, at any time during the Term thereof by giving written notice of exercise to the Company specifying the number of shares of Common Stock subject to the Stock Option or Stock Appreciation Right to be purchased. In the case of the exercise of a Stock Option, such notice shall be accompanied by payment in full of the aggregate purchase price (which shall equal the product of such number of Shares subject to such Stock Options multiplied by the applicable exercise price) per Share by certified or bank check, wire transfer or such other instrument or method as the Company may accept. If provided for in the applicable Award Agreement as approved by the Committee, payment in full or in part may also be made as follows:

(i)In the form of unrestricted Common Stock (by delivery of such shares or by attestation) already owned by the Participant of the same class as the Common Stock subject to the Stock Option (based on the Fair Market Value of the Common Stock on the date the Stock Option is exercised); provided, however, that, in the case of an Incentive Stock Option, the Participant shall only have the right to make a payment in the form of already owned shares of Common Stock of the same class as the Common Stock subject to the Stock Option if such right is set forth in the applicable Award Agreement.

(ii)To the extent permitted by applicable law, by delivering a properly executed exercise notice to the Company, together with a copy of irrevocable instructions to a broker to deliver promptly to the Company the amount of sale necessary to pay the purchase price, and, if requested, by the amount of any federal, state, local or foreign withholding taxes. To facilitate the foregoing, the Company may, to the extent permitted by applicable law, enter into agreements for coordinated procedures with one or more brokerage firms.

(iii)By instructing the Company to withhold a number of such shares having a Fair Market Value (based on the Fair Market Value of the Common Stock on the date the applicable Stock Option is exercised) equal to the product of (A) the exercise price per Share multiplied by (B) the number of shares of Common Stock in respect of which the Stock Option shall have been exercised.

(g)Delivery; Rights of Shareholders. A Participant shall not be entitled to delivery of Shares pursuant to the exercise of a Stock Option or Stock Appreciation Right until the exercise price therefor has been fully paid and applicable taxes have been withheld. Except as otherwise provided in Section 5(k), a Participant shall have all of the rights of a shareholder of the Company holding the class or series of Common Stock that is subject to such Stock Option or Stock Appreciation Right (including, if applicable, the right to vote the applicable Shares), when the Participant (i) has given written notice of exercise, (ii) if requested, has given the representation described in Section 15(a), and (iii) in the case of a Stock Option, has paid in full for such Shares.

(h)Nontransferability of Stock Options and Stock Appreciation Rights. No Stock Option or Stock Appreciation Right shall be transferable by a Participant other than, for no value or consideration, (i) by will or by the laws of descent and distribution; or (ii) in the case of a Nonqualified Stock Option or Stock Appreciation Right, as otherwise expressly permitted by the Committee including, if so permitted, pursuant to a transfer to such Participant’s family members, whether directly or indirectly or by means of a trust or partnership or otherwise (for purposes of the Plan, unless otherwise determined by the Committee, “family member” shall have the meaning given to such term in General Instructions A.1(a)(5) to Form S-8 under the Securities Act of 1933, as amended, and any successor thereto). Any Stock Option or Stock Appreciation Right shall be exercisable, subject to the terms of the Plan, only by the Participant, the guardian or legal representative of the Participant, or any person to whom such stock option is transferred pursuant to this Section 5(h), it being understood that the term “holder” and “Participant” include such guardian, legal representative and other transferee; provided, however, that the term

“Termination of Employment” shall continue to refer to the Termination of Employment of the original Participant.

(i)Termination of Employment. The effect of a Participant’s Termination of Employment on any Stock Option or Stock Appreciation Right then held by the Participant shall be set forth in the applicable Award Agreement or any other document approved by the Committee and applicable to such Stock Option or Stock Appreciation Right. In no event shall a Stock Option or Stock Appreciation Right be exercisable after the expiration of its term.

(j)Additional Rules for Incentive Stock Options. Notwithstanding any other provision of the Plan to the contrary, no Stock Option that is intended to qualify as an Incentive Stock Option may be granted (i) to any Eligible Individual who is not an Eligible Employee or (ii) to any Eligible Employee who at the time of such grant owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of any Subsidiary, unless at the time such Stock Option is granted the exercise price is at least 110% of the Fair Market Value of a Share and such Stock Option by its terms is not exercisable after the expiration of five years from the date such Stock Option is granted. In addition, the aggregate Fair Market Value of the Common Stock (determined at the time a Stock Option for the Common Stock is granted) for which Incentive Stock Options are exercisable for the first time by an optionee during any calendar year, under all of the Incentive Stock Option plans of the Company and of any Subsidiary, may not exceed $100,000. To the extent a Stock Option that by its terms was intended to be an Incentive Stock Option exceeds this $100,000 limit, the portion of the Stock Option in excess of such limit shall be treated as a Nonqualified Stock Option.

(k)Dividends and Dividend Equivalents. Dividends (whether paid in cash or Shares) and dividend equivalents may not be paid or accrued on Stock Options or Stock Appreciation Rights; provided that Stock Options and Stock Appreciation Rights may be adjusted under certain circumstances in accordance with the terms of Section 3(g).

Section 6.Restricted Stock

(a)Administration. Shares of Restricted Stock are actual Shares issued to a Participant that are subject to vesting or forfeiture provisions and may be awarded either alone or in addition to other Awards granted under the Plan. The Committee shall determine the Eligible Individuals to whom and the time or times at which grants of Restricted Stock will be

awarded, the number of shares to be awarded to any Eligible Individual, the conditions for vesting, the time or times within which such Awards may be subject to forfeiture and any other terms and conditions of the Awards, in addition to those contained in Section 6(c).

(b)Book Entry Registration or Certificated Shares. Shares of Restricted Stock shall be evidenced in such manner as the Committee may deem appropriate, including book-entry registration or issuance of one or more stock certificates. If any certificate is issued in respect of shares of Restricted Stock, such certificates shall be registered in the name of the Participant and shall bear an appropriate legend referring to the terms, conditions and restrictions applicable to such Award, substantially in the following form:

The transferability of this certificate and the shares of stock represented hereby are subject to the terms and conditions (including forfeiture) of the National Bank Holdings Corporation 2023 Omnibus Incentive Plan and an Award Agreement. Copies of such Plan and Award Agreement are on file at the offices of National Bank Holdings Corporation.

The Committee may require that the certificates evidencing such shares be held in custody by the Company until the restrictions thereon shall have lapsed and that, as a condition of any Award of Restricted Stock, the applicable Participant shall have delivered a stock power, endorsed in blank, relating to the Common Stock covered by such Award.

(c)Terms and Conditions. Shares of Restricted Stock shall be subject to the following terms and conditions and such other terms and conditions as are set forth in the applicable Award Agreement (including the vesting or forfeiture provisions applicable upon a Termination of Employment):

(i)The Committee shall, prior to or at the time of grant, condition (A) the vesting of an Award of Restricted Stock upon the continued service of the applicable Participant, or (B) the grant or vesting of an Award of Restricted Stock upon the attainment of Performance Goals or the attainment of Performance Goals and the continued service of the applicable Participant. The conditions for grant or vesting and the other provisions of Restricted Stock Awards (including, without limitation, any applicable Performance Goals) need not be the same with respect to each recipient.

(ii)Subject to the provisions of the Plan and the applicable Award Agreement, during the period, if any, set by the Committee, commencing with the date of such Restricted Stock Award for which such vesting restrictions apply (the “Restriction Period”), and until the

expiration of the Restriction Period, the Participant shall not be permitted to sell, assign, transfer, pledge or otherwise encumber Shares of Restricted Stock.

(d)Rights of a Shareholder. Except as provided in this Section 6 and the applicable Award Agreement, the applicable Participant shall have, with respect to the Shares of Restricted Stock, all of the rights of a shareholder of the Company holding the class or series of Common Stock that is the subject of the Restricted Stock, including, if applicable, the right to vote the shares and the right to receive any dividends. As determined by the Committee in the applicable Award Agreement and subject to Section 15(e), (i) cash dividends on the class or series of Common Stock that is the subject of the Restricted Stock Award shall be payable in cash and shall, as determined by the Committee, be either (A) held subject to the vesting of the underlying Restricted Stock, or held subject to meeting Performance Goals applicable only to dividends, or (B) distributed in full or in part without regard to the vested status of the underlying Restricted Stock; and (ii) dividends payable in Common Stock shall be paid in the form of Restricted Stock of the same class as the Common Stock with which such dividend was paid, and shall, as determined by the Committee, be either (A) held subject to the vesting of the underlying Restricted Stock, or held subject to meeting Performance Goals applicable only to dividends, or (B) distributed in full or in part without regard to the vested status of the underlying Restricted Stock.

(e)Delivery of Unlegended Certificates. If and when any applicable Performance Goals are satisfied and the Restriction Period expires without a prior forfeiture of the Shares of Restricted Stock for which legended certificates have been issued, unlegended certificates for such Shares shall be delivered to the Participant upon surrender of the legended certificates.

(f)Termination of Employment. The effect of a Participant’s Termination of Employment on any Restricted Stock then held by the Participant shall be set forth in the applicable Award Agreement or any other document approved by the Committee and applicable to such Restricted Stock.

Section 7.Restricted Stock Units

(a)Nature of Awards. Restricted stock units and deferred share rights (together, “Restricted Stock Units”) are Awards denominated in Shares that will be settled, subject to the terms and conditions of the Restricted Stock Units, in an amount in cash, Shares or both, based upon the Fair Market Value of a specified number of Shares.

(b)Terms and Conditions. Restricted Stock Units shall be subject to the following terms and conditions and such other terms and conditions as are set forth in the applicable Award Agreement (including the vesting or forfeiture provisions applicable upon a Termination of Employment):

(i)The Committee shall, prior to or at the time of grant, condition (A) the vesting of Restricted Stock Units upon the continued service of the applicable Participant, or (B) the grant or vesting of Restricted Stock Units upon the attainment of Performance Goals or the attainment of Performance Goals and the continued service of the applicable Participant. The conditions for grant or vesting and the other provisions of Restricted Stock Units (including, without limitation, any applicable Performance Goals) need not be the same with respect to each recipient. An Award of Restricted Stock Units shall be settled as and when the Restricted Stock Units vest, at a later time specified by the Committee in the applicable Award Agreement or, if the Committee so permits, in accordance with an election of the Participant.

(ii)Subject to the provisions of the Plan and the applicable Award Agreement, during the Restriction Period, if any, set by the Committee, the Participant shall not be permitted to sell, assign, transfer, pledge or otherwise encumber Restricted Stock Units.

(iii)The Award Agreement for Restricted Stock Units shall specify whether, to what extent and on what terms and conditions the applicable Participant shall be entitled to receive payments of cash, Common Stock or other property corresponding to the dividends payable on the Common Stock (subject to Section 15(e)).

(c)Rights of a Shareholder. A Participant to whom Restricted Stock Units are awarded shall have no rights as a shareholder with respect to the Shares represented by the Restricted Stock Units unless and until Shares are actually delivered to the Participant in settlement thereof. Unless otherwise determined by the Committee and subject to Section 15(e), an Award of Restricted Stock Units shall be adjusted to reflect deemed reinvestment in additional Restricted Stock Units of the dividends that would be paid and distributions that would be made with respect to the Award of Restricted Stock Units if it consisted of actual Shares. Notwithstanding the immediately preceding sentence, if an adjustment to an Award of Restricted Stock Units is made pursuant to Section 3(g) as a result of any dividend or distribution, no increase to such Award (by means of deemed reinvestment in additional Restricted Stock Units) shall be made under this Section 7(c) as a result of the same dividend or distribution.

(d)Termination of Employment. The effect of a Participant’s Termination of Employment on any Restricted Stock Units then held by the Participant shall be set forth in the applicable Award Agreement or any other document approved by the Committee and applicable to such Restricted Stock Units.

Section 8.Performance Units

Performance Units may be issued hereunder to Eligible Individuals, for no cash consideration or for such minimum consideration as may be required by applicable law, either alone or in addition to other Awards granted under the Plan. The Performance Goals to be achieved during any Performance Period and the length of the Performance Period shall be determined by the Committee upon the grant of each Performance Unit. The conditions for grant or vesting and the other provisions of Performance Units (including without limitation any applicable Performance Goals) need not be the same with respect to each recipient. Performance Units may be paid in cash, Shares, other property or any combination thereof, in the sole discretion of the Committee as set forth in the applicable Award Agreement.

Section 9.Other Stock-Based Awards

Other Stock-Based Awards may be granted either alone or in conjunction with other Awards granted under the Plan.

Section 10.Cash Awards

The Committee may grant Awards to Eligible Individuals that are denominated and payable in cash in such amounts and subject to such terms and conditions consistent with the terms of the Plan as the Committee shall determine. With respect to a Cash Award subject to Performance Goals, the Performance Goals to be achieved during any performance period and the length of the Performance Period shall be determined by the Committee upon the grant of such Cash Award.

Section 11.Change-in-Control Provisions

(a)General. Subject to Section 3(g) and notwithstanding any other provision of the Plan to the contrary, the provisions of this Section 11 shall apply to Awards (other than Annual Cash Awards), except to the extent the Committee specifically provides otherwise in an Award Agreement. With respect to Annual Cash Awards, the provisions of this Section

11 shall apply only if the Committee specifically provides for their application in the plan, policy or other arrangement governing such Annual Cash Awards.

(b)Impact of Change in Control. Upon the occurrence of a Change in Control, unless otherwise provided in the applicable Award Agreement:

(i)the applicable Performance Goal(s) for any performance-based Award shall be deemed achieved at the greater of (x) the applicable target level and (y) the level of achievement as determined by the Committee, taking into account performance through the latest date preceding the Change in Control as to which performance can, as a practical matter, be determined, which date shall not be later than the end of the applicable performance period; and

(ii)after giving effect to Section 11(b)(i), all then-outstanding Stock Options and Stock Appreciation Rights shall become fully vested and exercisable, and all Full-Value Awards and all Cash Awards shall vest in full, be free of restrictions, and be deemed to be earned and payable in an amount equal to the full value of such Award, except in each case to the extent that another Award meeting the requirements of Section 11(c) (any award meeting the requirements of Section 11(c), a “Replacement Award”) is provided to the Participant pursuant to Section 3(g) to replace such Award (any award intended to be replaced by a Replacement Award, a “Replaced Award”).

(c)Replacement Awards. An Award shall meet the conditions of this Section 11(c) (and hence qualify as a Replacement Award) if: (i) it is of the same type as the Replaced Award; (ii) it has a value equal to the value of the Replaced Award as of the date of the Change in Control, as determined by the Committee in its sole discretion consistent with Section 3(g); (iii) the underlying Replaced Award was an equity-based award, it relates to publicly traded equity securities of the Company or the entity surviving the Company following the Change in Control; (iv) it contains vesting and forfeiture terms (including with respect to vesting schedule and a Termination of Employment) that are not less favorable to the Participant than those of the Replaced Award (taking into account the rights on Termination of Employment set forth in Section 11(d) as applicable); and (v) its other terms and conditions are not less favorable to the Participant than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change in Control) as of the date of the Change in Control. Without limiting the generality of the foregoing, a Replacement Award may take the form of a continuation of the applicable Replaced Award if the requirements of the preceding sentence are satisfied. If a Replacement Award is granted, the Replaced Award shall not vest upon the Change in Control. The determination of whether the conditions of this Section 11(c) are satisfied shall be made by

the Committee, as constituted immediately before the Change in Control, in its sole discretion.

(d)Termination of Employment. Notwithstanding any other provision of the Plan to the contrary and unless otherwise determined by the Committee and set forth in the applicable Award Agreement, upon a Termination of Employment of a Participant by the Company other than for Cause or by the Participant for “good reason” (if and to the extent such term is defined in the Award Agreement or an Individual Agreement with the Participant) within 24 months following a Change in Control, (i) all Replacement Awards held by such Participant shall vest in full, be free of restrictions, and be deemed to be earned in full, and (ii) unless otherwise provided in the applicable Award Agreement, notwithstanding any other provision of the Plan to the contrary, any Stock Option or Stock Appreciation Right held by the Participant as of the date of the Change in Control that remains outstanding as of the date of such Termination of Employment may thereafter be exercised until the expiration of the stated full Term of such Nonqualified Stock Option or Stock Appreciation Right. For the avoidance of doubt, if the Participant’s Award Agreement or Individual Agreement contains provisions related to a Termination of Employment following a Change Control that conflict with this Section 11(d), the terms of such Award Agreement or Individual Agreement shall apply.

(e)Definition of Change in Control. For purposes of the Plan, a “Change in Control” shall mean the occurrence of any of the following events:

(i)An acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a “Person”) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 35% or more of either (A) the then-outstanding Shares of the Company (the “Outstanding Company Common Stock”), or (B) the combined voting power of the then-outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this subsection (i), the following acquisitions shall not constitute a Change in Control: (I) any acquisition directly from the Company, (II) any acquisition by the Company, (III) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any entity controlled by the Company, or (IV) any acquisition by any entity pursuant to a transaction which complies with clauses (A), (B), and (C) of subsection (iii) of this Section 11(e); or

(ii)A change in the composition of the Board such that the individuals who, as of the Effective Date, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that, for purposes of this

Section 11(e), any individual who becomes a member of the Board subsequent to the Effective Date whose election, or nomination for election by the Company’s shareholders, was approved by a vote of at least a majority of those individuals who are members of the Board and who were also members of the Incumbent Board (or deemed to be such pursuant to this proviso) shall be considered as though such individual were a member of the Incumbent Board; provided, further, that any such individual whose initial assumption of office occurs as a result of either an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board shall not be considered as a member of the Incumbent Board; or

(iii)The consummation of a reorganization, merger, statutory share exchange or consolidation or similar transaction involving the Company or any of its Subsidiaries, or sale or other disposition of all or substantially all of the assets of the Company, or the acquisition of assets or securities of another entity by the Company or any of its Subsidiaries (a “Business Combination”), in each case, unless, following such Business Combination, (A) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of, respectively, the then-outstanding shares of common stock (or, for a noncorporate entity, equivalent securities) and the combined voting power of the then-outstanding voting securities entitled to vote generally in the election of directors (or, for a noncorporate entity, equivalent securities), 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 Company or all or substantially all of the Company’s assets either directly or through one or more Subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be, (B) no Person (excluding any entity resulting from such Business Combination or any employee benefit plan (or related trust) of the Company or such entity resulting from such Business Combination) beneficially owns, directly or indirectly, 35% or more of, respectively, the then-outstanding shares of common stock (or, for a noncorporate entity, equivalent securities) of the entity resulting from such Business Combination or the combined voting power of the then-outstanding voting securities of such entity except to the extent that such ownership existed prior to the Business Combination, and (C) at least a majority of the members of the board of directors (or, for a noncorporate entity, equivalent body or committee) of the entity resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination; or

(iv)The approval by the shareholders of the Company of a complete liquidation or dissolution of the Company.

Notwithstanding any other provision of the Plan, any Award Agreement or any Individual Agreement, with respect to any Award that constitutes “nonqualified deferred compensation” within the meaning of Section 409A of the Code, a Change in Control shall not constitute a settlement or distribution event with respect to such Award, or an event that otherwise changes the timing of settlement or distribution of such Award, unless the Change in Control also constitutes a Section 409A Change in Control. For the avoidance of doubt, this paragraph shall have no bearing on whether an Award vests pursuant to the terms of the Plan or the applicable Award Agreement or Individual Agreement.

Section 12.Section 16(b); Section 409A

(a)The provisions of the Plan are intended to ensure that no transaction under the Plan is subject to (and all such transactions will be exempt from) the short-swing recovery rules of Section 16(b) of the Exchange Act (“Section 16(b)”). Accordingly, the composition of the Committee shall be subject to such limitations as the Board deems appropriate to permit transactions pursuant to the Plan to be exempt (pursuant to Rule 16b-3 promulgated under the Exchange Act) from Section 16(b), and no delegation of authority by the Committee shall be permitted if such delegation would cause any such transaction to be subject to (and not exempt from) Section 16(b).

(b)The Plan is intended to comply with the requirements of Section 409A of the Code or an exemption or exclusion therefrom and, with respect to amounts that are subject to Section 409A of the Code, it is intended that the Plan be administered in all respects in accordance with Section 409A of the Code. Each payment under any Award that constitutes nonqualified deferred compensation subject to Section 409A of the Code shall be treated as a separate payment for purposes of Section 409A of the Code. In no event may a Participant, directly or indirectly, designate the calendar year of any payment to be made under any Award that constitutes nonqualified deferred compensation subject to Section 409A of the Code. Notwithstanding any other provision of the Plan or any Award Agreement to the contrary, if a Participant is a “specified employee” within the meaning of Section 409A of the Code (as determined in accordance with the methodology established by the Company), amounts that constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code that would otherwise be payable by reason of a Participant’s Separation from Service during the six-month period immediately following such Separation from Service shall instead be paid or provided on the first business day following the date that is six months following the Participant’s Separation from Service. If the Participant dies

following the Separation from Service and prior to the payment of any amounts delayed on account of Section 409A of the Code, such amounts shall be paid to the personal representative of the Participant’s estate within 30 days following the date of the Participant’s death.

Section 13.Term, Amendment and Termination

(a)Effectiveness. The Plan was approved by the Board on March 23, 2023, subject to and contingent upon approval by the Company’s shareholders. The Plan will be effective as of the date of such approval by the Company’s shareholders (the “Effective Date”).

(b)Termination. The Plan will terminate on the tenth anniversary of the Effective Date. Awards outstanding as of such date shall not be affected or impaired by the termination of the Plan.

(c)Amendment of Plan. The Board or the Committee may amend, alter, or discontinue the Plan, but no amendment, alteration or discontinuation shall be made that would materially impair the rights of the Participant with respect to a previously granted Award without such Participant’s consent, except such an amendment made to comply with applicable law, including, without limitation, Section 409A of the Code, Applicable Exchange listing standards or accounting rules. In addition, no amendment shall be made without the approval of the Company’s shareholders to the extent such approval is required by applicable law or the listing standards of the Applicable Exchange, and the last sentence of Section 5(c) shall not be amended without the approval of the Company’s shareholders.

(d)Amendment of Awards. Subject to Section 5(c), the Committee may unilaterally amend the terms of any Award theretofore granted, but no such amendment shall without the Participant’s consent materially impair the rights of any Participant with respect to an Award, except such an amendment made to cause the Plan or Award to comply with applicable law, Applicable Exchange listing standards or accounting rules.

Section 14.Unfunded Status of Plan

It is intended that the Plan constitute an “unfunded” plan for incentive and deferred compensation. The Committee may authorize the creation of trusts or other arrangements to

meet the obligations created under the Plan to deliver Common Stock or make payments; provided, however, that unless the Committee otherwise determines, the existence of such trusts or other arrangements is consistent with the “unfunded” status of the Plan.

Section 15.General Provisions

(a)Conditions for Issuance. The Committee may require each person purchasing or receiving Shares pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the Shares without a view to the distribution thereof. The certificates for such Shares may include any legend that the Committee deems appropriate to reflect any restrictions on transfer. Notwithstanding any other provision of the Plan or agreements made pursuant thereto, the Company shall not be required to issue or deliver any certificate or certificates for Shares under the Plan prior to fulfillment of all of the following conditions: (i) listing, or approval for listing upon notice of issuance, of such Shares on the Applicable Exchange; (ii) any registration or other qualification of such Shares of the Company under any state or federal law or regulation, or the maintaining in effect of any such registration or other qualification that the Committee shall, in its absolute discretion upon the advice of counsel, deem necessary or advisable; and (iii) obtaining any other consent, approval, or permit from any state or federal governmental agency that the Committee shall, in its absolute discretion after receiving the advice of counsel, determine to be necessary or advisable.

(b)Additional Compensation Arrangements. Nothing contained in the Plan shall prevent the Company or any Subsidiary or Affiliate from adopting other or additional compensation arrangements for its employees.

(c)No Contract of Employment. The Plan shall not constitute a contract of employment, and adoption of the Plan shall not confer upon any employee any right to continued employment, nor shall it interfere in any way with the right of the Company or any Subsidiary or Affiliate to terminate the employment of any employee at any time.

(d)Required Taxes. No later than the date as of which an amount first becomes includible in the gross income of a Participant for federal, state, local or foreign income or employment or other tax purposes with respect to any Award under the Plan, such Participant shall pay to the Company, or make arrangements satisfactory to the Company regarding the payment of, any federal, state, local or foreign taxes of any kind required by law to be withheld with respect to such amount. Unless otherwise determined by the Company,

withholding obligations may be settled with Common Stock, including Common Stock that is part of the Award that gives rise to the withholding requirement, having a Fair Market Value on the date of withholding no greater than the maximum amount required to be withheld for tax purposes, all in accordance with such procedures as the Committee establishes. The obligations of the Company under the Plan shall be conditional on such payment or arrangements, and the Company and its Affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to such Participant. The Committee may establish such procedures as it deems appropriate, including making irrevocable elections, for the settlement of withholding obligations with Common Stock.

(e)Limitation on Dividend Reinvestment and Dividend Equivalents. Reinvestment of dividends in additional Restricted Stock at the time of any dividend payment, and the payment of Shares with respect to dividends to Participants holding Awards of Restricted Stock Units, shall only be permissible if sufficient Shares are available under Section 3 for such reinvestment or payment (taking into account then-outstanding Awards). If sufficient Shares are not available for such reinvestment or payment, such reinvestment or payment shall be made in the form of a grant of Restricted Stock Units equal in number to the Shares that would have been obtained by such payment or reinvestment, the terms of which Restricted Stock Units shall provide for settlement in cash and for dividend equivalent reinvestment in further Restricted Stock Units on the terms contemplated by this Section 15(e). In no event may any dividends or dividend equivalents with respect to any performance-based Awards be paid until vesting (if any) of such Awards.

(f)Designation of Death Beneficiary. The Committee shall establish such procedures as it deems appropriate for a Participant to designate a beneficiary to whom any amounts payable in the event of such Participant’s death are to be paid or by whom any rights of such Eligible Individual, after such Participant’s death, may be exercised.

(g)Subsidiary Employees. In the case of a grant of an Award to any employee of a Subsidiary, the Company may, if the Committee so directs, issue or transfer the Shares, if any, covered by the Award to the Subsidiary, for such lawful consideration as the Committee may specify, upon the condition or understanding that the Subsidiary will transfer the Shares to the employee in accordance with the terms of the Award specified by the Committee pursuant to the provisions of the Plan. All Shares underlying Awards that are forfeited or canceled revert to the Company.

(h)Governing Law and Interpretation. The Plan and all Awards made and actions taken thereunder shall be governed by and construed in accordance with the laws of the State

of Delaware, without reference to principles of conflict of laws. The captions of the Plan are not part of the provisions hereof and shall have no force or effect.

(i)Nontransferability. Except as otherwise provided in Section 5(h), Section 6(c)(ii) and Section 7(b)(ii) or as determined by the Committee, Awards under the Plan are not transferable except by will or by laws of descent and distribution.

(j)Clawback Policy. Awards are subject to the Company’s policies on, or any provisions in an Award Agreement or Individual Agreement with a Participant providing for, recoupment of gains realized from any Awards as may be in effect from time to time. All Awards granted under the Plan will be subject to recoupment in accordance with applicable law or any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law.
