Form of 2022

This Performance Units Integration Award Agreement (including any and all Appendices hereto, this “Award Agreement”) is entered into as of March 2, 2022 ("Grant Date"), by and between Old National Bancorp, an Indiana corporation (the “Company”), and [[FIRSTNAME]] [[LASTNAME]], an officer or employee of the Company or one of its Affiliates (the “Participant”).

A.    The Company adopted the Old National Bancorp Amended and Restated 2008 Incentive Compensation Plan, as amended (the “Plan”) to further the growth and financial success of the Company and its Affiliates by aligning the interests of participating officers and key employees ("participants") more closely with those of the Company's shareholders, to provide participants with an additional incentive to excel in performing services for the Company and its Affiliates and to promote teamwork among participants.

B.    The Company seeks to incentivize certain officers and key employees with additional equity compensation based on the realization of cost savings related to the integration of the Company and First Midwest Bancorp, Inc. (“First Midwest”) following their February 15, 2022 merger (the “Merger”).

C.    The Company believes that those goals can be achieved by granting Performance Units under the Plan to certain eligible officers and other key employees.

D.    The Talent Development and Compensation Committee (the “Committee”) of the Company’s Board has determined that a grant of Performance Units to the Participant, as provided in this Award Agreement, is in the best interests of the Company and its Affiliates and furthers the purposes of the Plan.

E.    The Participant wishes to accept the Company's grant of Performance Units set forth herein, subject to the terms and conditions of this Award Agreement and the Plan, and also wishes to confirm his or her acknowledgement and acceptance of the Company’s Stock Ownership Guidelines (as defined in Section 8 hereof) and Bonus Recoupment/Clawback Policy, as the same may be amended by the Company from time to time.

In consideration of the foregoing recitals and the mutual covenants herein contained, the Company and the Participant agree as follows:

1.    Certain Defined Terms. For purposes of this Award Agreement, if the first letter of a word (or each word in a term) is capitalized, the term shall have the meaning provided in this Award Agreement, or if such term is not defined by this Award Agreement, the meaning specified in the Plan. Unless the context otherwise requires, the following terms shall have the respective meanings assigned to them below for purposes of this Award Agreement:

(a)“Achieved Integration Performance Units,” “Initially Achieved Integration Performance Units” and “Incrementally Achieved Performance Units,” have the respective meanings set forth in Section 4(b).

(b)"Adjusted Share Distribution Amount" means a number of Shares equal to the sum of the Unadjusted Share Distribution and the Dividend Equivalent Adjustment.

(c)"Appendix A" and “Appendix B” means Appendix A and Appendix B, respectively, to this Award Agreement, each of which is hereby incorporated herein and made a part hereof.

(d)"Dividend Equivalent Adjustment" means, with respect to the Integration Performance Units covered by this Award Agreement, a number of Dividend Equivalents determined as provided in Section 6(c), which is added to the Unadjusted Share Distribution Amount to reflect cash dividend amounts paid to the Company’s common shareholders during the Performance Period on the Shares determined to be included in the Unadjusted Share Distribution Amount.

(e)“Dividend Equivalents” means dividend equivalents as contemplated by Section 10.06 of the Plan, payable in additional Shares on a contingent basis, subject in all cases to the achievement of the Performance Goals set forth herein and the vesting of the Integration Performance Units with respect to which such dividend equivalents are deemed paid.

(h)"Maximum Performance" means the Performance Goal attainment required for the maximum permissible amount of Integration Performance Units covered by this Award Agreement to be achieved (subject to vesting), as set forth in Appendix A.

(i)"Minimum Performance" means the minimum or threshold Performance Goal attainment required for any Integration Performance Units to be achieved (subject to vesting), described as such in Appendix A.

(j)"Performance Goal" means the financial target(s) or other performance factor(s) set forth in Appendix A, the attainment of which during the Performance Period (at least at a “Minimum” or “Threshold” level) is a condition to the distribution of any Shares in respect of any Integration Performance Units.

(k)"Performance Period" has the meaning set forth in Appendix A.

(l)"Performance Units" has the meaning set forth in the Plan.

(m)“Regular Vesting Date” has the meaning set forth in Section 6(g).

(q)    "Unadjusted Share Distribution Amount" means the total number of Shares distributable to the Participant (upon vesting), on a one-for-one basis for any Achieved Integration Performance Units, before adding the Dividend Equivalent Adjustment or subtracting Shares for required tax withholding.

2.    Incorporation of Plan Terms. All provisions of the Plan, including definitions (to the extent that a different definition is not provided in this Award Agreement), are incorporated herein by reference and expressly made a part of this Award Agreement. The Participant hereby acknowledges that he or she has received a copy of the Plan. Any inconsistencies between this Award Agreement (before giving effect to any such incorporation of any Plan provisions) and the Plan shall be resolved in favor of, and to give effect to, the provisions of this Award Agreement.

3.    Award of Integration Performance Units. The Committee has awarded the Participant [[SHARESGRANTED]] Integration Performance Units effective as of the Grant Date, conditioned on and subject to the terms and conditions of this Award Agreement and the Plan (the “Target Integration Performance Units”).

4.    Performance Goals and Achievement Determination

(a)     Performance Goals. The applicable Performance Goals, the weight given to each Performance Goal, and the Minimum Performance, Target Performance, and Maximum Performance are as set forth in Appendix A.

(b)    Committee Certification of Achievement of Performance Goals. Not more than thirty (30) days after the end of the Performance Period, the Committee shall review, determine and certify whether and, if so, at

what level any Performance Goal has been achieved above Minimum Performance for the Performance Period. The Committee in its discretion may review, determine and certify initial achievement of the Performance Goal above the Minimum Performance level before the end of the Performance Period and, if it does so, may accelerate the vesting and payment of the number of Integration Performance Units, or percentage relative to the Target Integration Performance Units, that would result from the achievement level the Committee may so earlier determine (“Initially Achieved Integration Performance Units”); provided, however, that no such earlier discretionary Committee determination shall be as of a date that is earlier than the one-year minimum performance and vesting period provided in the Plan. After any such initial Committee determination before the end of the Performance Period, and on such a quarterly or other periodic basis as the Committee deems appropriate thereafter through the end of the Performance Period, the Committee may review, determine and certify any incremental, additional Performance Goal attainment (above the level, if any, determined to have been initially achieved) and the number of additional Integration Performance Units, or additional percentage relative to the Target Integration Performance Units, that would result from that incremental, additional Performance Goal achievement under this Award Agreement (“Incrementally Achieved Integration Performance Units” and, together with the Initially Achieved Integration Performance Units, referred to as the “Achieved Integration Performance Units”).

(a)    Conditional Integration Performance Unit Award. Except as otherwise provided in Section 7 or subsections (b) through (d) of this Section 5, no Integration Performance Units will vest or otherwise be deemed earned, and no distributions of Shares will be made (and no entitlement to the same will apply), (i) unless and until at least Minimum Performance is achieved or exceeded in accordance with the Performance Goal set out in Appendix A, as certified by the Committee in accordance with Section 4(b), and (ii) unless the Participant is continuously employed by the Company or an Affiliate during the entire period from the award of the Integration Performance Units until the related, final Regular Vesting Date (as defined in Section 6(g)), absent the Committee’s waiver of such continuous employment requirement in its discretion.

(b)    Participant Disability. If the Participant Terminates Service on account of the Participant’s Disability occurring either during the Performance Period or between the end of the Performance Period and any final Regular Vesting Date thereafter, the Participant’s Integration Performance Units that remain outstanding immediately prior to such Termination shall remain outstanding as if the Participant had not Terminated Service, and payments via Share distributions with respect to any such outstanding Integration Performance Units shall be made as of the same Regular Vesting Date(s) and subject to the same Performance Goal requirements as payments that are made to participants who did not incur such a Termination of Service. As used herein, “Disability” has the meaning set forth in the Participant’s employment agreement with the Company (including any such agreement as has been assumed in the Merger, an “Employment Agreement”) or, if not there so defined, in any applicable Company long-term disability policy or as otherwise may be determined by the Committee.

(c)    Participant Death. If the Participant Terminates Service due to death during the Performance Period or thereafter prior to any final Regular Vesting Date, then with respect to the Participant’s Integration Performance Units that remain outstanding immediately prior to such Termination, all performance requirements shall lapse and, on the date of such Termination of Service, the Participant’s Beneficiary shall be fully entitled to payment in Shares with respect to any such outstanding Integration Performance Units, determined as if Target Performance had been achieved and the Performance Period ended on the date of the Participant’s death. In such circumstances, payment via distribution of Shares shall be made within sixty (60) days after the Participant’s death.

(d)    Involuntary Non-Cause Termination by the Company or Good Reason Termination by the Participant. Upon either (i) a Termination of Service by the Company not covered by Section 5(b) or (c) and for any reason other than Cause (defined under the Plan to incorporate by reference the Participant’s Employment Agreement definition thereof) or Unacceptable Performance (if the same is defined in the Participant’s Employment Agreement), or (ii) a Termination resulting from the Participant’s resignation for Good Reason (also defined under the Plan to incorporate by reference the Participant’s Employment Agreement definition), and further subject in either case to the Release condition set forth in the following sentence, then with respect to the Participant’s Integration Performance Units that remain outstanding immediately prior to such Termination of Service, all performance requirements shall lapse and 100% of such Integration Performance Units remaining outstanding shall become Achieved Integration Performance Units (as if Target Performance had been achieved and the Performance Period ended on the date of such Termination). In any such circumstances, payment via a lump sum distribution of Shares shall be made within sixty (60) days after such Termination of Service, provided that the Participant has executed and delivered to the Company a written release pursuant to applicable Employment Agreement requirements (a “Release”) and any revocation period applicable to such Release has expired.

(a)    Distributions in Shares. All payments on account of any Achieved Integration Performance Units shall be made in the form of whole shares of the Company’s voting common stock (“Shares”) distributed to the Participant as provided in this Award Agreement. Any such Share distributions may be made via the Company’s establishment of a book entry account for such Shares in the name of the Participant.

(b)    Determination of Unadjusted Share Distribution Amount. Any Unadjusted Share Distribution Amount shall be calculated on a one-for-one basis relative to the number of Achieved Integration Performance Units, if any, certified by the Committee as of any determination date. By way of example, and as further described in Appendix A, (i) if Minimum Performance (75% of the Performance Goal) is achieved in the first year of the Performance Period and so certified by the Committee, then 50% of the Target Integration Performance Units would become Initially Achieved Integration Performance Units, and the Unadjusted Share Distribution Amount would consist of one share of the Company's common stock for each of such Achieved Integration Performance Units; and (ii) if Target/Maximum Performance or greater is subsequently achieved by the Company and certified by the Committee as of any later time in the Performance Period, the remaining 50% of the Target Integration Performance Units will become Incrementally Achieved Integration Performance Units.

(c)    Determination of Adjusted Share Distribution Amount. Except as otherwise provided for in this Award Agreement, a Dividend Equivalent Adjustment shall be added to any Unadjusted Share Distribution Amount in order to determine the number of Shares constituting the Adjusted Share Distribution Amount in connection with any certified Performance Goal attainment. The Dividend Equivalent Adjustment shall be a number of Integration Performance Units equal to the number of Integration Performance Units that would have resulted if each cash dividend paid during the Performance Period on the Shares included in that Unadjusted Share Distribution Amount had been reinvested in Shares.

(d)    Reduction for Applicable Tax Withholding. After calculating any such Adjusted Share Distribution Amount, the number of Shares to be distributed on account of the Achieved Integration Performance Units shall be reduced by applicable tax withholdings as provided in Section 10 of this Award Agreement and Article XV of the Plan.

(e)    Rounding Down to Avoid Fractional Shares. If, after deducting Shares from any such Adjusted Share Distribution Amount sufficient to cover applicable tax withholdings, the Participant would be entitled to a fractional Share as part of any distribution of Shares, the net number of Shares then distributable to the Participant under this Award Agreement shall be rounded down to the next whole number of Shares.

(f)    Retained Committee Discretion. Notwithstanding any other provision of this Award Agreement, the Committee may, in its sole discretion, reduce or increase the number of Shares that may be distributed as determined pursuant to the Adjusted Share Distribution Amount calculation set forth above. The preceding sentence shall not apply to reduce a distribution made pursuant to Section 7.

(g)    Timing of Any Share Distributions. Except as otherwise provided in Sections 5(c), 5(d) or 7, after the Committee has certified initial or subsequent incremental achievement of any Performance Goal as provided in Section 4(b), the Company shall distribute the relevant Adjusted Share Distribution Amount, reduced to reflect tax withholding and any related downward rounding to eliminate any fractional shares, within thirty (30) days after the date of such Committee determination (each such date of distribution of Shares being referred to as a “Regular Vesting Date”). No Shares shall be paid or distributed earlier than one (1) year from the Closing Date of the Merger.

(h)    No Shareholder Rights Prior to Share Distribution. Because this is an award of Performance Units and not actual Shares of Company common stock, the Participant shall not have any rights or privileges as a shareholder of the Company based on the award of any Integration Performance Units or the achievement of any Performance Goals, unless and until Shares have been recorded on the Company’s official shareholder records (or the records of its transfer agent or registrar) as having been issued and distributed to the Participant (or his or her Beneficiary) after vesting in accordance herewith. In illustration and not in limitation of the foregoing, prior to vesting and such issuance and distribution of Shares to the Participant, the Participant shall not have any voting rights or, except as expressly provided herein with respect to contingent rights to Dividend Equivalents as part of any Adjusted Share Distribution Amount, any rights to receive dividends with respect to or based on any Integration Performance Units.

     7.    Change in Control Terms. If a Change in Control of the Company occurs after the Grant Date and during the Performance Period, Article XVI of the Plan shall govern the disposition of Integration Performance Units awarded under this Award Agreement.

8.    Participant’s Investment Representations; Stock Ownership Guideline Covenants. Before the distribution of Shares with respect to any Achieved Integration Performance Units, the Participant shall provide any written investment representations reasonably requested by the Company. At the time any such Shares are distributed, if the Participant is subject to, and does not then satisfy, the Company’s Stock Ownership Guidelines for executives and directors, as may be amended and in effect from time to time and as set forth in the applicable section of the Company’s Corporate Governance Guidelines posted on the Company’s website or as otherwise established by the Committee (the “Stock Ownership Guidelines”), the Participant shall continue to hold the Shares distributed to the Participant (net of Shares withheld for taxes) until such time thereafter as the Participant first or again satisfies the Stock Ownership Guidelines.

9.    Restrictive Covenants Applicable to the Participant. By executing and accepting this Award Agreement, and in consideration of the award of the Integration Performance Units to the Participant, the Participant: (a) hereby agrees to comply with and be bound by the restrictive covenants contained in Appendix B (the “Restrictive Covenants”); (b) understands and acknowledges that (i) the grant of Integration Performance Units pursuant to this Award Agreement, and (ii) any vesting or distribution of Shares to the Participant with respect thereto, are expressly conditioned on and subject to the Participant’s continuing compliance with each of the Restrictive Covenants; and (c) understands and acknowledges that the Company may seek and obtain any and all available remedies for any non-compliance with the Restrictive Covenants, in addition to the forfeiture of any Performance Units. The Restrictive Covenants are independent of and in addition to (not in replacement of) any covenants on the same or similar subjects to which the Participant may have previously agreed in any employment, confidentiality, non-solicitation, non-competition, severance, change in control, incentive compensation grant or award or other agreement to which the Participant is a party or by which he or she is bound, all of which other agreements shall remain in full force and effect.

10.    Income and Employment Tax Withholding. All required federal, state, city, and local income and employment taxes that arise on account of the Integration Performance Units shall be satisfied through the withholding of Shares otherwise distributable as a part of the Adjusted Share Payment Amount pursuant to this Award Agreement.

11.    Nontransferability. Unless and until vested in accordance with the terms of this Award Agreement, the Participant's interest in the Integration Performance Units or any contingent rights to any distribution of any Shares with respect to such Integration Performance Units may not be (i) sold, transferred, assigned, margined, encumbered, bequeathed, gifted, alienated, hypothecated, pledged, or otherwise disposed of, whether by operation of law, whether voluntarily or involuntarily or otherwise, other than by will or by the laws of descent and distribution, or (ii) subject to execution, attachment, or similar process. Any attempted or purported transfer in contravention of this Section shall be null and void from the start and of no force or effect whatsoever. Following the execution of this Award Agreement, the Participant may expressly designate a death beneficiary (“Beneficiary”) by completing and delivering a designation of beneficiary agreement (“Beneficiary Designation”) and delivering a copy of the Beneficiary Designation to the Company. In the event the Participant does not designate a beneficiary, then the applicable state law shall determine succession.

12.    Indemnity. The Participant hereby agrees to indemnify and hold harmless the Company and its Affiliates (and their respective directors, officers and employees), and the Committee, from and against any and all losses, claims, damages, liabilities and expenses based upon or arising out of the incorrectness or alleged incorrectness of any investment representation made by Participant to the Company under Section 8 or any failure on the part of the Participant to perform any agreements contained herein. The Participant hereby further agrees to release and hold harmless the Company and its Affiliates (and their respective directors, officers and employees) from and against any tax liability, including without limitation, interest and penalties, incurred by the Participant in connection with his or her participation in the Plan.

13.    Changes in Shares. In the event of any change in the Shares as described in Section 4.04 of the Plan, the Committee shall make such adjustment or substitution in the number or kind of Performance Units or shares subject to, or the terms of, this Award Agreement as it deems appropriate and consistent with such Section 4.04, so that the contingent economic value of the Performance Units covered by this Award Agreement remains substantially the same.

14.    No Rights to Future Awards or Continued Employment. Nothing in the Plan or this Award Agreement creates any right for the Participant to receive, or any obligation on the part of the Company to grant to the Participant, any future awards of any kind under the Plan. In addition, nothing in the Plan or this Award Agreement confers any rights or obligations on the Participant to continued employment or service with the Company or any of its Affiliates or affects in any manner the right of the Company or its Affiliates or the Participant to terminate the Participant’s employment or service to the Company or any of its Affiliates at any time, subject to

the terms of any employment agreement between the Participant and the Company or any of its Affiliates and any Plan terms applicable to Terminations for Good Reason.

15.    Committee Determinations; Other Interpretive Matters. Any and all determinations made by the Committee under and as permitted by the Plan with respect to this Award Agreement or the Plan (including any made pursuant to Section 13 hereof) shall be conclusive, final and binding upon the Participant and any and all of his or her heirs, executors, administrators or others purporting to derive any rights or claims by or through the Participant. Except where otherwise specified or the context otherwise requires, (i) references such as “herein,” “hereto” or “hereof” refer to this Award Agreement in its entirety, including any and all Appendices hereto, (ii) “including” and similar references whenever used herein mean “including, without limitation,” and (iii) the descriptive headings of the Sections and, where applicable, subsections of this Award Agreement are inserted for convenience only and shall not affect the interpretation of this Award Agreement.

16.    Governing Law. To the extent not otherwise governed by the laws of the United States (including the Internal Revenue Code), this Award Agreement shall be governed by and construed in accordance with the laws of the State of Indiana, without reference to the choice of law principles thereof.

17.    Jury Trial Waiver. The Company and the Participant hereby knowingly, voluntarily and irrevocably waive any right to a trial by jury of any dispute under or action relating to this Award Agreement (including the Appendices hereto) and agree that any such dispute or action shall be tried before a judge sitting without a jury.

18.    Survival. The provisions of Sections 1, 2 and 4 through 17, inclusive, including Appendices A and B as incorporated in any of the foregoing, Sections 19 and 20 and this Section 18 of this Award Agreement, as well as the Restrictive Covenants contained in Appendix B hereto, will survive the expiration or termination of this Award Agreement, the vesting or forfeiture of any Integration Performance Units and distribution of Shares in respect of any Achieved Integration Performance Units pursuant hereto and/or any Termination of the Participant’s employment or service for any reason whatsoever.

19.    Counterparts. This Award Agreement may be executed in two (2) or more counterparts, each of which will be deemed an original, but all of which collectively will constitute one and the same agreement.

20.    Recoupment/Clawback. Any grant of Integration Performance Units under this Award Agreement or any other award granted or paid to the Participant under the Plan, whether in the form of stock options, stock appreciation rights, restricted stock, performance shares, performance units, stock or cash, is subject to recoupment or “clawback” by the Company in accordance with the Company’s Bonus Recoupment/Clawback Policy, as may be amended and in effect from time to time and as set forth in the applicable “Bonus Recoupment Policy” section of the Company’s Corporate Governance Guidelines posted on the Company’s website or as otherwise established by the Committee.

IN WITNESS WHEREOF, the Company, by its officer thereunder duly authorized, and the Participant, have caused this Award Agreement to be executed as of the day and year first above written.

The number of Shares payable on account of the Integration Performance Units covered by this Award Agreement (before any Dividend Equivalent Adjustment or tax withholding) will be based on the results of the following relative performance factor ("Performance Factor") during the Performance Period:

•Realization during the Performance Period of annualized, run-rate cost savings, relative to the established Integration Performance Target outlined below, as determined by the Company in accordance with this Award Agreement

“Performance Weighting Fraction” means the relative weighting assigned to the above-identified Performance Factor(s) in determining the number of Shares to be distributed (before any Dividend Equivalent Adjustment or tax withholding) with respect to the Achieved Integration Performance Units. For purposes of this Award Agreement, the Performance Weighting Fraction is as follows:

Overall Attainment of Certain Integration Performance Levels. If the Company’s Integration Performance Level equals 75%, then Minimum Performance is achieved and 50% of the Target Integration Performance Units will become Achieved Integration Performance Units and a like number of Shares constitute the resulting Unadjusted Share Payment Amount(s). No Shares will be paid with respect to any Performance Units unless at least Minimum Performance is achieved.

If the Integration Performance Level is 100% or more, then Maximum Performance is achieved and 100% of the Target Integration Performance Units will become Achieved Integration Performance Units and a like number of Shares constitute the resulting Unadjusted Share Payment Amount. No additional Shares will be paid with respect to the Integration Performance Units for any Integration Performance Level achievement above 100%.

The table below shows the percentage of the Target Integration Performance Units that become total Achieved Integration Performance Units and the resulting Unadjusted Share Distribution Amount(s) (before any Dividend Equivalent Adjustment or tax withholding) issuable in Shares at selected Integration Performance Levels, subject to the Participant’s satisfaction of the vesting requirements described in Section 5(a) of this Award Agreement:

Linear interpolation shall be applied between the 75% and 100% Integration Performance Levels shown in the first column of the table above to determine the resulting percentage of Target Integration Performance Units achieved for the Performance Period and the resulting total number of Achieved Integration Performance Units and related Unadjusted Share Distribution Amount(s), subject to satisfaction of applicable vesting requirements. For example, if the Company’s percentage achievement of the Integration Performance Target and resulting Integration Performance Level were 85%, then 70% of the Target Integration Performance Units would become Achieved Integration Performance Units; if that percentage attainment and resulting Integration Performance Level were 95%, the number of such Achieved Integration Performance Units would equal 90% of the Target Integration Performance Units.

Calculations for Serial, Incremental Increases in Achieved Integration Performance Level during Performance Period. If the Company attains a higher Integration Performance Level on a date subsequent to (i) the Committee determination of any prior Performance Level achievement above Minimum Performance and resulting certification of Achieved Integration Performance Units (and like Unadjusted Share Distribution Amounts) and (ii) the distribution of Shares to the Participant with respect thereto (after giving effect to the appropriate tax withholding reduction and rounding down to avoid distribution of any fractional shares), then a subsequent Unadjusted Share Distribution Amount shall be determined for the Incrementally Achieved Integration Performance Units certified by the Committee for such higher Integration Performance Level attainment (after deducting any Unadjusted Share Distribution Amounts for any previously determined Achieved Integration Performance Units). Calculation of the Adjusted Share Distribution Amount and number of Shares to be distributed shall be made separately each time any Achieved Integration Performance Units and related Unadjusted Share Distribution Amounts are determined and certified by the Committee--in each case, adjusting the relevant Unadjusted Share Distribution Amount for Dividend Equivalents thereon, and then reducing the resulting Adjusted Share Distribution Amount for applicable tax withholdings and downward reduction to avoid any fractional shares, as provided in Sections 6(c) through (e) of this Award Agreement. Only upward adjustments for subsequently higher Integration Performance Level attainment shall be made under this paragraph.

As an example, assume that: the Participant received an award of 1,000 Target Integration Performance Units; on March 31, 2023, the Committee certified a 75% Integration Performance Level (75% achievement of the Integration Performance Target) based on results as of February 28, 2023; and on March 15, 2024, the Committee certified an additional, incremental 15% achievement of the Integration Performance Target through February 15, 2024, representing ultimate Integration Performance Level attainment of 90% by the end of the Performance Period. As of March 31, 2023, the number of Initially Achieved Integration Performance Units and the Unadjusted Share Distribution Amount would be 500 (50% of the Target Integration Performance Units), that amount would be increased for the Dividend Equivalent Adjustment on the related 500 Shares and the resulting Adjusted Share Distribution Amount would be subject to further reduction for tax withholding and any downward rounding to avoid fractional shares before Shares were distributed upon the related vesting and Share distribution date. As of March 15, 2024, the number of Incrementally Achieved Integration Performance Units and the related Unadjusted Share Distribution Amount would be 300 (determined by deducting the 500 Integration Performance Units and Shares previously certified as achieved from the 800 Integration Performance Units and Shares ultimately achieved at the final 90% Performance Level). As with the prior year calculation, that 300 Incrementally Achieved Integration Performance Unit/Unadjusted Share Distribution amount would be increased for the Dividend Equivalent Adjustment on the related 300 Shares, and the resulting Adjusted Share Distribution Amount would be further reduced for tax withholding and any downward rounding to avoid the distribution of fractional shares.

The Committee will review and certify the Company’s achievement of the Performance Factor as provided in Section 4(b) of this Award Agreement and may exercise its good faith discretion, consistent with Article III of the Plan, to interpret or adjust the Performance Factor, its attainment by the Company or the terms of this Award Agreement. Without limiting the foregoing, except as otherwise provided in Section 6(f), the Committee reserves the right, in its sole discretion, to reduce or increase the amount of any award. Shares distributable in respect of any Achieved Integration Performance Units will be distributed in accordance with the timing set forth in Section 6(g) of this Award Agreement.

3.Safeguarding, and Non-Use and Non-Disclosure, of Confidential Information

a.Value and Importance of Confidentiality Protections. The Participant acknowledges and agrees that (i) by virtue of Participant’s employment, Participant will be given access to and use of Confidential Information, (ii) the Company has devoted (and will continue to devote) substantial time, money, and effort to develop Confidential Information and maintain the proprietary and confidential nature thereof, and (iii) Confidential Information is proprietary and confidential and, if any Confidential Information were disclosed or became known by persons engaging in a business in any way competitive with the Company's Business, such disclosure would result in hardship, loss, irreparable injury, and damage to the Company, the measurement of which would be difficult, if not impossible, to determine. Accordingly, the Participant agrees that the preservation and protection of Confidential Information is an essential part of Participant’s duties of employment and that, as a result of the Participant’s employment with the Company, Participant has a duty of fidelity, loyalty, and trust to the Company in safeguarding Confidential Information.

b.Confidentiality Covenants. At all times both during and after the Termination of the Participant’s employment with the Company: (i) the Participant will hold as strictly confidential, and take all steps necessary to protect and safeguard Confidential Information; (ii) the Participant will not, directly or indirectly, use, or otherwise employ any Confidential Information, except for such use as reasonably required in the ordinary course of Participant’s employment by the Company, and then solely during the term of such Company employment and exclusively for the Company’s benefit; and (iii) the Participant will not, directly or indirectly, disclose, distribute, communicate, disseminate or reveal any Confidential Information to any Person, except for such disclosure (A) to other Company employees who reasonably “need to know” the same to discharge their responsibilities to the Company, but only during the term of the Participant’s employment with the Company or (B) as legally required by any court or governmental agency (as by subpoena or similar mandatory legal process or court order), but only after prompt notice to the Company to permit it to seek a protective order or other confidential treatment of the Confidential Information being sought and then only to the extent any portions of such Confidential Information are legally required to be disclosed. The Participant shall follow all Company policies and procedures regarding Confidential Information and shall exercise utmost diligence and take any additional precautions necessary or

appropriate under the particular circumstances to safeguard, and protect against any prohibited use or disclosure of, any Confidential Information.

c.Duration. The confidentiality obligations contained in this Agreement shall continue as long as Confidential Information remains confidential or protectable as a trade secret under applicable laws (except that such obligations shall continue if Confidential Information loses its confidential nature through improper use or disclosure, including but not limited to any breach of the Restrictive Covenants in this Appendix B) and, in the case of any Third-Party Confidential Information, for so long as the Company remains contractually or otherwise legally obligated to protect the same.

d.Exceptions. Notwithstanding the foregoing, nothing in this Appendix B prohibits, limits, or restricts, or shall be construed to prohibit, limit, or restrict, the Participant from exercising any legally protected whistleblower rights (including pursuant to Section 21F of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder), without notice to or consent from the Company. Moreover, pursuant to the federal Defend Trade Secrets Act of 2016: (i) an individual will not be held criminally or civilly liable under any federal or state trade secret laws for the disclosure of a trade secret that is made (A) in confidence, to a federal, state or local government official or to a lawyer, solely for the purpose of reporting or investigating a suspected violation of law; or (B) in a complaint or other document filed in a lawsuit or other legal proceeding, if such filing is made “under seal” (meaning that it is not accessible to the public); and (ii) an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order.

4.    Remedies. The Company will suffer irreparable damage and injury and will not have an adequate remedy at law if the Participant breaches any provision of the Restrictive Covenants in this Appendix B. Accordingly, in addition to any and all other remedies that may be available to the Company, the Company shall be entitled to seek injunctive relief to prevent or halt actual, attempted or threatened breaches of the Participant’s Restrictive Covenants, or to enforce specifically their terms, without proving actual damages or posting any bond or other security. The rights and remedies of the Company set forth in this Appendix B and in this Award Agreement generally are cumulative with, and not exclusive or in lieu of, other rights and remedies available to the Company at law or in equity. In addition, the Company will retain the right to take appropriate disciplinary action against the Participant for violations of the Restrictive Covenants or any Company policies during the Participant’s employment by the Company. The existence of any claim or cause of action that the Participant has against the Company, whether predicated on this Award Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of the Restrictive Covenants.

5.    Periods of Noncompliance and Reasonableness of Periods. The Restrictive Covenants shall be deemed not to run during any periods of noncompliance by the Participant, the intention of the parties being to have such restrictions and covenants apply for the full periods contemplated by this Appendix B (including those specified following the Participant’s Termination of employment with the Company). The Company and the Participant acknowledge and agree that the Restrictive Covenants are reasonable in view of the nature of the Company's Business and the Participant's advantageous knowledge of and familiarity with the Company's Business, operations, affairs, Customers and Prospective Customers. The Restrictive Covenants are essential terms and conditions to the Company entering into this Award Agreement, and they shall be construed as independent of any other provision in this Award Agreement or of any other agreement between the Participant and the Company. Notwithstanding anything contained herein to the contrary, if the scope of any restriction or covenant is found by a court of competent jurisdiction to be too broad to permit enforcement of such restriction or covenant as written, then such restriction or covenant shall be enforced to the maximum extent permitted by law. The Participant and the Company hereby acknowledge the same and authorize any such court to strike or modify any such provision or part thereof, to permit enforcement of the Restrictive Covenants and this Award Agreement to the fullest extent permitted by law.

6.    Survival. The Restrictive Covenants shall survive termination or expiration of this Award Agreement and any Termination of the Participant’s employment with the Company.

7.    Reimbursement of Certain Costs. If the Participant breaches or threatens to breach any of the Restrictive Covenants in this Appendix B and the Company initiates legal action against the Participant and substantially prevails against the Participant in such action by enforcing such Restrictive Covenants or obtaining damages for such breaches, the Company shall be entitled to payment or reimbursement from the Participant of the Company’s reasonable costs and expenses in connection with such action (including reasonable attorneys' fees and disbursements, litigation costs and investigative and expert witness fees and costs).
