Form of Peoples Bancorp Inc. Fourth Amended and Restated 2006 Equity Plan Performance-Based Restricted Stock Award Agreement used and to be used to evidence grants of performance-based restricted common shares to executive officers of Peoples Bancorp Inc. after April 27, 2023

    This Performance-Based Restricted Stock Award Agreement (this “Agreement”) is made effective as of ________(the “Grant Date”) by and between Peoples Bancorp Inc. (the “Company”) and __________(the “Participant”). Capitalized terms not defined in this Agreement shall have the meanings given to them in the Plan (as defined below).

The Company hereby grants to the Participant an award of _________(____) shares of restricted Company Stock (the “Restricted Performance Stock”), subject to the terms and conditions described in the Peoples Bancorp Inc. Fourth Amended and Restated 2006 Equity Plan (the “Plan”) and this Agreement.

(A)    Vesting. Subject to the Participant’s continued employment with the Company or one of its Subsidiaries, and the provisions of the Plan (including Article XI thereof) and this Agreement, the Restricted Performance Stock shall vest in full on the ______ (__) anniversary of the Grant Date (the “Vesting Date”) provided the Company has achieved the “Annual Performance Goals” detailed below for each of the fiscal years which ends during the period beginning on the Grant Date and ending on the Vesting Date (each such fiscal year constitutes a “Performance Period”).

In the event that the Company does not achieve the Annual Performance Goals with respect to one or more Performance Periods, the portion of the Restricted Performance Stock which shall vest on the Vesting Date shall be determined by multiplying the number of shares of Company Stock subject to the Restricted Performance Stock by a fraction, the numerator of which is the number of Performance Periods with respect to which the Company achieved the Annual Performance Goals and the denominator of which is the number of Performance Periods during the period beginning on the Grant Date and ending on the Vesting Date.

(B)    Transfer Restrictions. Until the Restricted Performance Stock vests as described herein, the Restricted Performance Stock may not be sold, transferred, pledged, assigned or otherwise alienated or hypothecated. Except as otherwise provided herein, Restricted Performance Stock that vests as described in Section 2(A), less any shares of Company Stock withheld for the payment of taxes, shall be or become transferable as follows:

(i)Fifty percent (50%) of the net vested Restricted Performance Stock shall be immediately transferable; and

(ii)Fifty percent (50%) of the net Restricted Performance Stock shall become transferable upon the Participant’s Termination.

(C)    Effect of Termination. Notwithstanding anything to the contrary in Sections 2(A) and 2(B) of this Agreement:

(i)Death. If the Participant dies prior to the Vesting Date, a portion of the Restricted Performance Stock, determined as described below, shall become fully vested and transferable on the date of death and the remaining unvested portion of the Restricted Performance Stock shall be forfeited immediately on the date of death:

(I)    If the Participant dies prior to the end of the initial Performance Period, none of the Restricted Performance Stock shall vest.

(II)    If the Participant dies prior to the end of any Performance Period after the initial Performance Period and the Company has achieved the Annual Performance Goals with respect to each Performance Period completed prior to the Participant’s death, the portion of the Restricted Performance Stock which shall vest shall be determined by multiplying the number of shares of Company Stock subject to the Restricted Performance Stock by a fraction, the numerator of which is the number of whole months elapsed during the period beginning on the Grant Date and ending on the date of the Participant’s death, and the denominator of which is the number of whole months in the period beginning on the Grant Date and ending on the Vesting Date.

(III)    If the Participant dies prior to the end of any Performance Period after the initial Performance Period and the Company has not achieved the Annual Performance Goals with respect to one or more of the Performance Periods completed prior to the Participant’s death, the portion of the Restricted Performance Stock which shall vest shall be determined by: multiplying (1) the number of shares of Company Stock subject to the Restricted Performance Stock by (2) a fraction, the numerator of which is a number equal to (a) the number of whole months elapsed during the period beginning on the Grant Date and ending on the date of the Participant’s death, less (b) a number equal to the product of (i) number of Performance Periods completed since the Grant Date and prior to the Participant’s death for which the Performance Goals were not achieved, multiplied by (ii) 12, and the denominator of which is the number of whole months in the period beginning on the Grant Date and ending on the Vesting Date.

(ii)Disability or Retirement. If the Participant Terminates due to Disability or Retirement prior to the Vesting Date, the Restricted Performance Stock shall become vested and transferable at the time and subject to the conditions specified in Section 2(A). For the purpose of this Award Agreement, Retirement means a Termination by a Participant other than due to death or Disability on or after attaining 62 years of age and with at least 5 years of service with the Company or any Subsidiary.

(iii)    Terminations for Cause or Any Reason Other than Death, Disability or Retirement. If the Participant is Terminated for Cause or Terminates for any reason other than due to death, Disability or Retirement prior to the Vesting Date, all of the unvested Restricted Performance Stock shall be forfeited immediately on the Termination date.

(D)    Delivery of Shares. As soon as reasonably practicable after the Restricted Performance Stock becomes transferable, the Company shall deliver to the Participant a stock certificate for, or other appropriate documentation evidencing, the number of shares of Company Stock with respect to which the restrictions on transferability have lapsed.

Section 3    Rights of the Participant Before Vesting

Before the Restricted Performance Stock vests, (A) the Participant may exercise full voting rights associated with the shares of Company Stock underlying the Restricted Performance Stock, and (B) dividends which would otherwise be received during the Restriction Period shall be accrued and paid to the Participant in the same proportion and at the same time as the underlying Restricted Performance Stock vests, if at all, and any dividends paid in shares of Company Stock shall be subject to the same restrictions as the shares of Restricted Performance Stock granted under this Agreement.

Section 4    Covenants

(A)Non-Solicitation. The Participant acknowledges and understands that the Participant’s contacts with customers or potential customers of the Company and its Subsidiaries are due, at least in part, to the support and assistance provided by the Company during the term of the Participant’s employment, and therefore, that soliciting, diverting or appropriating such persons would unfairly harm the Company and its Subsidiaries. As a result, the Participant agrees that, during the term of the Participant’s employment and for a period of one (1) year thereafter, the Participant shall not, directly or indirectly:

(i) Contact any customer or prospective customer of the Company or any of its Subsidiaries, on the Participant’s behalf or on behalf of any other person or entity, of whom the Participant had knowledge, actual or imputed, or with whom the Participant had contact in whatever form during the Participant’s employment with the Company or any of its Subsidiaries for the purpose of soliciting the business of such person or inducing such person to acquire from any person or entity other than the Company or any of its Subsidiaries any product or service that currently is provided or under development by the Company or any of its Subsidiaries; or

(ii)    Attempt to solicit, or assist anyone in attempting to solicit, any employee of the Company or any of its Subsidiaries to terminate the employee’s employment with the Company or any of its Subsidiaries.

(B)Non-Disclosure of Confidential Information. The Participant acknowledges and understands that during the course of the Participant’s employment with the Company and/or its Subsidiaries, the Participant shall have access to Confidential Information (as defined below) that is maintained as confidential by the Company and its Subsidiaries, is highly valuable and

proprietary to the Company and its Subsidiaries, and the disclosure of which to third parties, or the unauthorized access, acquisition, use, or attempted access, acquisition or use, of which would cause the Company and its Subsidiaries serious and unfair competitive disadvantage and harm. As a result, the Participant agrees that, during the Participant’s employment with the Company or any of its Subsidiaries, and at all times thereafter, regardless of the reason for the Termination of such employment:

(i)     The Participant shall not disclose to any third parties any Confidential Information or use such Confidential Information for any purpose other than to carry out the Participant’s employment responsibilities for the Company or any of its Subsidiaries;

(ii)     The Participant shall treat such Confidential Information as confidential, as required by law and this Agreement;

(iii)     The Participant shall only access, acquire, use, or attempt to access, acquire, or use, Confidential Information for use in performing the Participant’s duties for the Company or one of its Subsidiaries, and for no other reason; and

(iv)    Immediately upon Termination of the Participant’s employment for any reason, to return to the Company all Confidential Information in the Participant’s possession or control, as well as any Copies (as defined below) made of such Confidential Information and any other material, including handwritten notes, made or derived from such Confidential Information;

(v)     For purposes of this Agreement:

(I) “Confidential Information” means all trade secrets and proprietary information in whatever form (whether communicated orally or in documentary or other tangible form) belonging to the Company or any of its Subsidiaries that has not been published or disseminated or otherwise become a matter of public knowledge other than as a result of the Participant’s acts or omissions, including without limitation: business plans, financial or accounting information, rates, insurance payment and reimbursement information, research and development information, marketing or sales information, customer lists, lists of potential customers, contact information for any customer or potential customer, processes, computer programs, systems and software (including, without limitation, documentation and related source and object codes), customer renewal and expiration information, associate information, on-site program and support materials, training programs and associated materials, pricing lists, contracts, forms, methods, procedures and analyses and any other information that the Company or one of its Subsidiaries takes measures to prevent, in the ordinary course of business, from being available to persons other than those selected by the Company or one of its Subsidiaries.

(II)“Copies” includes all Confidential Information stored or maintained in electronic format or on electronic or magnetic media of any sort, including, without limitation, computer servers, PDAs, cell phones, I-Pods, smart cards, Blackberries, hard drives, zip drives, floppy disks, CD-ROMs, DVDs, and magnetic tapes.

(C)    Reasonableness of Restraints; Irreparable Harm; Breach No Defense. The Participant acknowledges that:

(i)    The covenants described in this Section 4 are reasonably necessary to protect the goodwill, trade secrets, and other legitimate business interests of the Company and its Subsidiaries and that such restraints shall not cause the Participant any undue hardship.

(ii)    Any breach of the covenants contained in this Section 4 would cause the Company or one of its Subsidiaries immediate and irreparable harm for which injunctive relief would be necessary and proper, and the Participant consents to the issuance of a temporary restraining order and a preliminary injunction upon good faith presentment by the Company or one of its Subsidiaries of allegations demonstrating such breach without the necessity of proving damages or posting a bond therefor; provided, however, that nothing contained herein shall be construed to prohibit the Company or any of its Subsidiaries from pursuing all other legal remedies at its disposal including but not limited to monetary damages.

(iii)The covenants of this Section 4 are essential to this Agreement. They shall be construed as independent of any other provision in this Agreement, and the existence of any claim or cause of action which the Participant may have against the Company or any of its Subsidiaries, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company or one of its Subsidiaries of these covenants.

(iv)If the scope of any restriction contained in this Section 4 is too broad to permit enforcement of such restriction to its fullest extent, then such restriction shall be enforced to the maximum extent permitted by law, and the Participant hereby consents and agrees that such scope may be judicially modified accordingly in any proceeding brought to enforce such restriction.

Section 5    Restricted Performance Stock Subject to Plan; Plan as Controlling

By entering into this Agreement, the Participant agrees and acknowledges that the Participant has received and read a copy of the Plan. All terms and conditions of the Plan applicable to the Restricted Performance Stock which are not set forth in this Agreement shall be deemed incorporated herein by reference. In the event any term or condition of this Agreement is inconsistent or conflicts with the terms and conditions of the Plan, the Plan shall be deemed controlling. This agreement is also subject to the terms and conditions of the Peoples Bancorp Inc. Executive Incentive Compensation Clawback Policy.

If the Committee determines that (A) the listing, registration or qualification of the shares of Company Stock underlying the Restricted Performance Stock upon NASDAQ or any other established stock exchange, market or quotation system or under any state or federal law; (B) the consent or approval of any governmental or regulatory body; or (C) an agreement by the Participant with respect thereto, is necessary or desirable as a condition to the issuance of the shares of Company Stock underlying the Restricted Performance Stock, the shares of Company Stock may not be issued unless and until such listing, registration, qualification, consent, approval, or agreement has been effected or obtained, free of any conditions which are not acceptable to the Committee.

If any shares of Company Stock subject to the Restricted Performance Stock are issued upon the vesting thereof to a person who, at the time of such vesting or thereafter, is an affiliate of the Company for purposes of Rule 144 promulgated under the Securities Act of 1933, as amended

(the “Securities Act”), or are issued in reliance upon exemptions under the securities laws of any state, then upon such issuance:

(i)    Unless permitted by the Plan, such shares of Company Stock shall not be transferable by the holder thereof, and neither the Company nor its transfer agent or registrar, if any, shall be required to register or otherwise to give effect to any transfer thereof and may prevent any such transfer, unless the Company shall have received an opinion from its counsel to the effect that any such transfer would not violate the Securities Act or the applicable laws of any state; and

(ii)    The Company may cause any stock certificate which may evidence any of such shares of Company Stock to bear a legend reflecting the applicable restrictions on the transfer thereof.

Section 7    Tax Withholding

The Company shall have the power and the right to deduct or withhold, or require the Participant to remit to the Company, the minimum statutory amount to satisfy federal, state and local taxes required by law or regulation to be withheld with respect to any taxable event arising as a result of the Plan. With respect to withholding required upon any taxable event arising as a result of the Restricted Performance Stock, the Participant may elect, subject to the approval of the Committee, to satisfy the withholding requirement, in whole or in part, by having the Company withhold shares of Company Stock having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax that could be imposed on the transaction. All such elections shall be irrevocable, made in writing and signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

Section 8    Miscellaneous

(A)No Guarantee of Continued Employment. The grant of Restricted Performance Stock under this Agreement shall not: (i) confer upon the Participant any right to continue in the employ of the Company or any of its Subsidiaries; (ii) limit in any way the right of the Company or any Subsidiary to Terminate the Participant; or (iii) be evidence of any agreement or understanding, express or implied, that the Participant has a right to continue as an employee for any period of time or at any particular rate of compensation.

If the Participant has not made an effective beneficiary designation, the deceased Participant’s beneficiary shall be the Participant’s surviving spouse or, if there is no surviving spouse, the deceased Participant’s estate. The identity of a Participant’s designated beneficiary shall be based only on the information included in the latest beneficiary designation form completed by the Participant and shall not be inferred from any other evidence.
