Peoples Bancorp Inc. (“Peoples”) and NB&T Financial Group, Inc. (“NB&T Financial”), have entered into an Agreement and Plan of Merger dated as of August 4, 2014 (the “Merger Agreement”), which provides for the merger of NB&T Financial with and into Peoples (the “Merger”). Consummation of the Merger is subject to certain conditions, including, but not limited to, obtaining the requisite vote of the shareholders of Peoples and NB&T Financial and the approval of the Merger by various regulatory agencies.

Peoples will not issue any fractional shares of common stock in connection with the Merger. Instead, each holder of NB&T Financial common shares who would otherwise be entitled to receive a fraction of a Peoples common share (after taking into account all shares of NB&T Financial common shares owned by such holder at the effective time of the Merger) will receive cash, without interest, in an amount equal to the Peoples fractional common share to which such holder would otherwise be entitled to multiplied by the average closing sale price of a Peoples common share on the NASDAQ Global Select Market^® for the 10 consecutive trading days immediately preceding the effective date of the Merger.

Peoples and NB&T Financial will each hold a special meeting of its shareholders to vote on the adoption and approval of the Merger Agreement. The special meeting of Peoples’ shareholders will be held at: 10: 00 am, local time, on March 3, 2015, at the Lafayette Hotel, 101 Front Street, Marietta, Ohio 45750. The special meeting of NB&T Financial’s shareholders will be held at: 9:00 am, local time, on March 3, 2015, at NB&T Financial’s main office at 48 North South Street, Wilmington, Ohio 45177.

At each special meeting, shareholders will be asked to approve and adopt the Merger Agreement, and the transactions contemplated thereby, including the Merger. Shareholders will also be asked to approve the adjournment of the special meeting, if necessary, to solicit additional proxies in favor of the Merger Agreement and the transactions contemplated thereby, including the Merger.

This document is a proxy statement of both Peoples and NB&T Financial, that each is using to solicit proxies for use at their respective special meetings of shareholders to vote on the Merger. It is also a prospectus relating to Peoples’ issuance of its common shares in connection with the Merger. This joint proxy statement/prospectus describes Peoples’ special meeting, NB&T Financial’s special meeting, the Merger proposal and other related matters.

The boards of directors of Peoples and NB&T Financial each approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and recommend that shareholders vote “FOR” the approval of the Merger Agreement, and “FOR” the approval of the adjournment of the special meeting, if necessary, to solicit additional proxies in the event there are not sufficient votes at the time of the special meeting to adopt and approve the Merger Agreement.

Peoples’ common shares are traded on the NASDAQ Global Select Market^® under the symbol “PEBO.” On August 4, 2014, the date of execution of the Merger Agreement, the closing price of Peoples’ common shares was $24.08 per share. On January 21, 2015, the closing price of Peoples’ common shares was $24.10 per share. NB&T Financial’s common shares are traded on the NASDAQ Capital Market^® under the symbol “NBTF.” On August 4, 2014, the date of execution of the Merger Agreement, the closing price of NB&T Financial’s common shares was $20.98. On January 21, 2015, the closing price of NB&T Financial’s common shares was $30.34.

You are encouraged to read this document, including the materials incorporated by reference into this document, carefully. In particular, you should read the “Risk Factors” section beginning on page 29 for a discussion of the risks related to the Merger and owning Peoples common shares after the Merger.

Whether or not you plan to attend your company’s special meeting, your board urges you to vote by completing, signing and returning the enclosed proxy card in the enclosed postage-paid envelope.

If you are an NB&T Financial shareholder as of January 9, 2015, the record date, and you do not vote your shares in favor of the adoption and approval of the Merger Agreement, under the Ohio General Corporation Law (“OGCL”), you will have the right to demand the fair cash value for your NB&T Financial common shares. To exercise your “dissenters’ rights”, you must adhere to the specific requirements of the OGCL; see “DISSENTERS’ RIGHTS” on page 45 of this joint proxy statement/prospectus and the complete text of the applicable sections of the OGCL attached to this joint proxy statement/prospectus as Annex B. No holder of Peoples common shares is entitled to exercise any rights of a dissenting shareholder under the OGCL.

Not voting by proxy or at the special meeting will have the same effect as voting against the adoption and approval of the Merger Agreement. Your board urges you to read carefully this joint proxy statement/prospectus, which contains a detailed description of your company’s special meeting, the Merger proposal, Peoples’ common shares to be issued in the Merger and other related matters.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of Peoples common shares to be issued in the Merger or determined if this joint proxy statement/prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The securities to be issued in connection with the Merger described in this joint proxy statement/prospectus are not savings accounts, deposit accounts or other obligations of any bank or savings association and are not insured by the Federal Deposit Insurance Corporation, the Deposit Insurance Fund or any other federal or state governmental agency.

Notice is hereby given that a special meeting of the shareholders of NB&T Financial Group, Inc. (“NB&T Financial”) will be held at 9:00 am, local time, on March 3, 2015, at NB&T Financial’s main office at 48 North South Street, Wilmington, Ohio 45177, for the purpose of considering and voting on the following matters:

Holders of record of NB&T Financial common shares at the close of business on January 9, 2015, the record date, are entitled to notice of and to vote at the special meeting and any adjournment or postponement of the special meeting. The affirmative vote of the holders of at least a majority of NB&T Financial’s shares is required to adopt and approve the Agreement and Plan of Merger.

A proxy statement/prospectus and proxy card for the special meeting are enclosed. A copy of the Agreement and Plan of Merger is attached as Annex A to the proxy statement/prospectus.

Your vote is very important, regardless of the number of shares of NB&T Financial common stock you own. Please vote as soon as possible to make sure that your shares of common stock are represented at the special meeting. If you are a holder of record, you may cast your vote in person at the special meeting or, to ensure that your shares of NB&T Financial common stock are represented at the special meeting, you may vote your shares by completing, signing and returning the enclosed proxy card. If your shares are held in a stock brokerage account or by a bank or other nominee (in “street name”), please follow the voting instructions provided by your broker, bank or nominee.

The NB&T Financial board of directors unanimously recommends that you vote (1) “FOR” the adoption and approval of the Agreement and Plan of Merger, (2) “FOR” the approval of the specified compensation, and (3) “FOR” the proposal to adjourn the special meeting, if necessary, to solicit additional proxies.

Neither Peoples nor NB&T Financial has authorized anyone to provide you with any information other than the information included in this document and documents which are incorporated by reference. If anyone provides you with different or inconsistent information, you should not rely on it. You should assume that the information appearing in this document and the documents incorporated by reference are accurate only as of their respective dates. Each of Peoples’ and NB&T Financial’s business, financial condition, results of operations and prospects may have changed since those dates.

The following are answers to certain questions that you may have regarding the special meetings. You are urged to read carefully the remainder of this document because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the appendices to, and the documents incorporated by reference in, this document.

This joint proxy statement/prospectus contains important information about the Merger and the special meetings of the shareholders of Peoples and NB&T Financial, and you should read it carefully. The enclosed voting materials allow you to vote your company’s common shares without attending the special meeting.

Peoples believes that the Merger is in the best interests of its shareholders and will benefit Peoples and its shareholders by enabling Peoples to further expand into the markets currently served by NB&T Financial and strengthening the competitive position of the combined organization. Furthermore, Peoples believes its increased asset size after the Merger will create additional economies of scale and provide opportunities for asset and earnings growth in an extremely competitive banking environment. To review Peoples’ reasons for the Merger in more detail, see “THE MERGER—Peoples’ Reasons for the Merger” on page 67 of this joint proxy statement/prospectus.

Peoples common share (after taking into account all shares of NB&T Financial common shares owned by such holder at the effective time of the Merger) will receive cash, without interest, in an amount equal to the Peoples fractional common share to which such holder would otherwise be entitled multiplied by the average closing sale price of a Peoples common share on the NASDAQ Global Select Market^® for the 10 consecutive trading days immediately preceding the effective date of the Merger.

The shareholders of NB&T Financial will be asked to (1) vote to adopt and approve the Merger Agreement; (2) vote to approve the advisory (non-binding) proposal on specified compensation, (3) vote to approve the adjournment of the special meeting to solicit additional proxies if there are not sufficient votes at the time of the special meeting to adopt and approve the Merger Agreement; and (4) vote on any other business which properly comes before the special meeting.

The special meetings may be adjourned, if necessary, to solicit additional proxies in the event there are not sufficient votes at the time of the special meeting to adopt and approve the Merger Agreement. The affirmative vote of the holders of a majority of the Peoples and NB&T Financial common shares represented, in person or proxy, at the respective special meeting is required to adjourn such special meeting. In addition, the affirmative vote of a majority of the NB&T Financial and Peoples common shares

represented in person or by proxy at the respective special meeting and entitled to vote at the special meeting is required to approve the NB&T Financial advisory (non-binding) proposal on specified compensation and the Peoples proposal to issue up to 3,500,000 common shares in connection with the Merger, respectively.

If you hold your Peoples or NB&T Financial common shares in the name of a broker, bank or other nominee, please see the discussion below regarding shares held in “street name.”

If you mark “ABSTAIN” on your proxy card or ballot with respect to the NB&T Financial proposal to approve the specified compensation or the adjournment of your company’s special meeting, if necessary, to solicit additional proxies, it will have the same effect as a vote “AGAINST” the proposal. The failure to return your proxy card or vote in person, however, will have no effect on the proposal to approve the specified compensation or on the proposal to adjourn your company’s special meeting, if necessary, to solicit additional proxies.

As a Peoples shareholder, if you sign, date and return your proxy card and do not indicate how you want your common shares held outside the Peoples Retirement Savings Plan to be voted, then your shares will be voted “FOR” the adoption and approval of the Merger Agreement, “FOR” the approval of the issuance of common shares and, if necessary, “FOR” the approval of the adjournment for the special meeting to solicit additional proxies. All shares held in the Peoples Retirement Savings Plan for which timely and complete voting instructions are not received will not be voted.

Assuming a quorum is present, if you are a Peoples or NB&T Financial shareholder and you do not instruct your broker, bank or other nominee on how to vote your shares,

Under the rules of the NASDAQ Stock Market, brokers who hold shares in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not allowed to exercise their voting discretion with respect to the approval of matters that the NASDAQ determines to be “non-routine” without specific instructions from the beneficial owner. It is expected that all proposals to be voted on at the Peoples and NB&T Financial special meetings are such “non-routine” matters. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the broker does not have discretionary voting power.

NB&T Financial shareholders may revoke a proxy at any time before a vote is taken at the special meeting by: (i) filing a written notice of revocation with NB&T Financial’s Corporate Secretary, at 48 North South Street, Wilmington, Ohio 45177; (ii) executing and returning another proxy card with a later date; or (iii) attending the special meeting and giving notice of revocation in person.

Your attendance at the special meeting will not, by itself, revoke your proxy.

If you hold your common shares in “street name” and you have instructed your broker, bank or nominee to vote your common shares, you must follow directions received from your broker, bank or nominee to change your vote.

Peoples’ primary business activities are conducted through Peoples Bank, a full-service community bank. Peoples Bank was first chartered as an Ohio banking corporation under the name “The Peoples Banking and Trust Company” in Marietta, Ohio, in 1902 and reorganized as a national banking association under its current name in 2000. Peoples Bank, as a national bank, is subject to regulation, examination and oversight by the Office of the Comptroller of the Currency (the “OCC”), the Board of Governors of the Federal Reserve System (the “Federal Reserve”) and the Consumer Financial Protection Bureau (the “CFPB”). Peoples Bank’s products and services include traditional banking products, such as deposit accounts, lending products and trust services. Peoples Bank provides services through traditional branch offices, ATMs and telephone and internet-based banking. Brokerage services are offered exclusively through an unaffiliated registered broker-dealer located at Peoples Bank’s offices. Peoples also makes available credit cards to consumers and businesses, as well as merchant credit card processing services, through joint marketing arrangements with third parties.

Peoples Insurance was first chartered in 1994 as an Ohio corporation under the name “Northwest Territory Property and Casualty Insurance Agency, Inc.” In late 1995, Peoples Insurance was awarded insurance agency powers in the State of Ohio, becoming the first insurance agency in Ohio to be affiliated with a financial institution. In 2009, Peoples Insurance was converted from an Ohio corporation to an Ohio limited liability company under its current name.

Peoples Investment Company, its subsidiary Peoples Capital Corporation, and PBNA, L.L.C. were formed to optimize Peoples’ consolidated capital position and provide new investment opportunities as a means of enhancing profitability. These opportunities include, but are not limited to, investments in low-income housing tax credit funds or projects, venture capital and other higher risk investments that Peoples Bank is limited or restricted from participating in. Presently, the operations of these companies do not represent a material part of Peoples’ overall business activities.

Through Peoples’ financial services units noted above, Peoples makes a complete line of banking, investment, insurance and trust solutions available to its customers and clients. These products and services include the following:

•

various demand deposit accounts, savings accounts, money market accounts and certificates of deposit;

•

commercial, consumer and real estate mortgage loans (both commercial and residential) and lines of credit;

•

debit and ATM cards;

•

corporate and personal trust services;

•

safe deposit rental facilities;

•

money orders and cashier’s checks;

•

full range of life, health and property and casualty insurance products; and

At September 30, 2014, Peoples had total assets of approximately $2.4 billion, total loans of approximately $1.5 billion, total deposits of approximately $1.8 billion, and total shareholders’ equity of approximately $319.3 million.

Peoples’ common shares are traded on the NASDAQ Global Select Market^® (sometimes referred to herein as, the “NASDAQ”) under the symbol “PEBO”. Peoples is subject to the reporting requirements under the

NB&T Financial is a financial holding company which owns all of the issued and outstanding common shares of NBTC. NBTC is engaged in the commercial banking business primarily in southwestern Ohio, providing a variety of consumer and commercial financial services. The primary business of NBTC consists of accepting deposits, through various consumer and commercial deposit products, and using such deposits to fund loans secured by residential and non-residential real estate, commercial and agricultural loans and consumer loans, including automobile loans. All of the foregoing deposit and lending services are available at each of NBTC’s full-service offices. NBTC also has a trust department with assets under management of approximately $263.2 million. NBTC also, through its wholly-owned subsidiary, NB&T Insurance Group, Inc., offers annuities and brokerage services to NBTC’s customers. As of June 30, 2014, NBTC had 205 employees.

On December 31, 2009, Community National Corporation (“CNC”) merged into NB&T Financial and CNC’s subsidiary, Community National Bank (“CNB”), located in Franklin, Ohio, merged into NBTC. The merger added approximately $86 million to NB&T Financial’s assets and $76 million in deposits. CNB had five branches located in Warren, Montgomery and Butler counties in Ohio. NB&T Financial paid $3.6 million in cash and issued 237,582 common shares of NB&T Financial in exchange for all of the outstanding common shares of CNC.

On March 19, 2010, NBTC assumed all the deposits and acquired certain assets and other liabilities of American National Bank in Parma, Ohio, from the Federal Deposit Insurance Corporation (the “FDIC”), pursuant to the terms of a purchase and assumption agreement. As part of the acquisition, NBTC and the FDIC entered into loss-sharing agreements that collectively covered approximately $48.2 million of assets, consisting almost entirely of commercial real estate loans and commercial and industrial loans. In 2012, the FDIC and NBTC terminated the single-family loss-sharing agreement which covered approximately $800,000 of remaining assets.

As a registered financial holding company under the Bank Holding Company Act, NB&T Financial is subject to regulation, examination and oversight by the Federal Reserve. NBTC, as a national bank, is subject to regulation, examination and oversight by the OCC, the Federal Reserve and the CFPB. NBTC is a member of the Federal Reserve Bank of Cleveland. In addition, since its deposits are insured by the FDIC, NBTC is also subject to some regulation, oversight and special examination by the FDIC. NBTC must file periodic financial reports with the FDIC, the OCC and the Federal Reserve Bank of Cleveland. Examinations are conducted periodically by these federal regulators to determine whether NBTC and NB&T Financial are in compliance with various regulatory requirements and are operating in a safe and sound manner.

Since its incorporation in 1980, NB&T Financial’s activities have been limited primarily to holding the common shares of NBTC.

At September 30, 2014, NB&T Financial had total assets of approximately $649.9 million, total loans of approximately $401.2 million, total deposits of approximately $557.2 million and total shareholders’ equity of approximately $71.2 million.

NB&T Financial’s common shares are traded on the NASDAQ Capital Market^® (sometimes referred to herein as, the “NASDAQ”) under the symbol “NBTF.” NB&T Financial is subject to the reporting requirements under the Securities Exchange Act of 1934, as amended, and, therefore, files reports, proxy statements and other information with the SEC. Further important business and financial information about NB&T Financial is incorporated by reference into this joint proxy statement/prospectus. See “INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE” on page 101 of this joint proxy statement/prospectus.

The Merger (page 46)

The Merger Agreement provides that, if all of the conditions are satisfied or waived, NB&T Financial will be merged with and into Peoples, with Peoples surviving. Thereafter, at a later time specified by Peoples Bank in its certificate of merger filed with the OCC, NBTC will be merged with and into Peoples Bank. The Merger Agreement is attached to this joint proxy statement/prospectus as Annex A and is incorporated in this joint proxy statement/prospectus by reference. We encourage you to read the Merger Agreement carefully, as it is the legal document that governs the Merger.

What NB&T Financial shareholders will receive in the Merger (page 86)

Under the terms of the Merger Agreement, shareholders of NB&T Financial will be entitled to receive from Peoples, after the Merger is completed, merger consideration payable in the form of a combination of cash and Peoples common shares to be calculated as set forth in the Merger Agreement. At the effective time of the Merger, each NB&T Financial common share will be converted into the right to receive: (i) 0.9319 Peoples common share, and (ii) $7.75 in cash, subject to adjustment under certain circumstances set forth in the Merger Agreement. The Merger Agreement requires that the Merger consideration be adjusted if either: (i) the number of NB&T Financial common shares outstanding immediately prior to the effective time of the Merger exceeds the number of shares outstanding as of the date the Merger Agreement was signed, with certain exceptions for stock benefit plans, or (ii) Peoples changes the number of its common shares outstanding prior to the effective time of the Merger by way of a stock split, stock dividend, recapitalization or similar transaction with respect to the outstanding Peoples common shares, and the record date is prior to the effective time. Following the Merger, NB&T Financial sharesholders will own approximately 18% of the outstanding Peoples common shares. Additionally, while NB&T Financial has historically paid a $0.30 per share quarterly dividend, Peoples currently pays a $0.15 per share quarterly dividend.

In addition, if, prior to the effective time of the Merger and during the time period specified in the Merger Agreement, both the market value of Peoples’ common shares and the NASDAQ Bank Index drop below certain pre-determined thresholds, NB&T Financial will have the right to terminate the Merger Agreement, unless Peoples increases the exchange ratio for the stock portion of the Merger consideration to an extent specified in the Merger Agreement.

Peoples will not issue any fractional shares of common stock in connection with the Merger. Instead, each holder of NB&T Financial common shares who would otherwise be entitled to receive a fraction of a Peoples common share (after taking into account all shares of NB&T Financial common shares owned by such holder at the effective time of the Merger) will receive cash, without interest, in an amount equal to the Peoples fractional common share to which such holder would otherwise be entitled multiplied by the average closing sale price of a Peoples common share on the NASDAQ for the 10 consecutive trading days immediately preceding the effective date of the Merger.

What holders of NB&T Financial Stock Options will receive (page 87)

to $31.00 less the exercise price per share of such NB&T Financial stock option. The vesting of all unvested NB&T Financial stock options will be accelerated immediately prior to cancellation in exchange for the cash payment.

As of December 31, 2014, there were outstanding NB&T Financial stock options to purchase 234,050 shares, 194,038 of which were vested. As of December 31, 2014, 218,050 NB&T Financial common shares, or 93.2% of all outstanding option shares, are held by directors and executive officers of NB&T Financial, and options to purchase 16,000 shares, or 6.8%, are held by other individuals. The average exercise price of the outstanding NB&T Financial stock options is $19.78. The aggregate cash payment to the holders of NB&T Financial stock options will be approximately $2,626,314.

Exchange of NB&T Financial common shares (page 87)

Once the Merger is complete, Wells Fargo Shareowner Services, as exchange agent (the “Exchange Agent”), will mail you transmittal materials and instructions for exchanging your NB&T Financial stock certificates for Peoples’ common shares to be issued by book-entry transfer.

A special meeting of shareholders of NB&T Financial will be held at 9:00 am, local time, on March 3, 2015, at NBTC’s main office at 48 North South Street, Wilmington, Ohio 45177, for the purpose of considering and voting on the following matters:

As of the same date, there were no NB&T Financial preferred shares outstanding or eligible to be voted at the NB&T Financial special meeting.

Peoples special meeting of shareholders (page 40)

A special meeting of shareholders of Peoples will be held at 10:00 am, local time, on March 3, 2015, at the Lafayette Hotel, 101 Front Street, Marietta, Ohio 45750, for the purpose of considering and voting on the following matters:

•

a proposal to adopt and approve the Merger Agreement;

•

a proposal to approve the issuance of up to 3,500,000 Peoples common shares to be issued in connection with the Merger;

As of January 21, 2015, a total of 14,836,735 Peoples common shares were outstanding and eligible to be voted at the Peoples special meeting. As of the same date, there were no Peoples preferred shares outstanding or eligible to be voted at the Peoples special meeting.

Required vote (pages 35, 40)

The adoption and approval of the Merger Agreement by Peoples will require the affirmative vote of the holders of at least 7,418,368 Peoples common shares, which, as of January 21, 2015, is a majority of the Peoples common shares outstanding and entitled to vote at the Peoples special meeting. A quorum, consisting of the holders of 7,418,368 of the outstanding Peoples common shares, must be present in person or by proxy at the Peoples special meeting before any action, other than the adjournment of the special meeting, can be taken. The affirmative vote of the holders of a majority of the Peoples common shares represented, in person or proxy, at the special meeting is required to adjourn the special meeting, if necessary, to solicit additional proxies.

The adoption and approval of the Merger Agreement by NB&T Financial will require the affirmative vote of the holders of at least 1,720,749 NB&T Financial common shares, which is a majority of the NB&T Financial common shares outstanding and entitled to vote at the NB&T Financial special meeting. A quorum, consisting of the holders of 1,720,749 of the outstanding NB&T Financial common shares, must be present in person or by proxy at the NB&T Financial special meeting before any action, other than the adjournment of the special meeting, can be taken. The affirmative vote of the holders of a majority of the NB&T Financial common shares represented, in person or proxy, at the special meeting is required to adjourn the special meeting, if necessary, to solicit additional proxies.

As of January 21, 2015, directors of Peoples owned an aggregate of 381,951 Peoples common shares, an amount equal to approximately 2.6% of the outstanding Peoples common shares. As of the same date, directors of NB&T Financial owned an aggregate of 441,489 NB&T Financial common shares, an amount equal to approximately 12.8% of the outstanding NB&T Financial common shares.

No beneficial owners of Peoples common shares have made a commitment to vote in favor of the adoption and approval of the Merger Agreement. The directors of NB&T Financial, who collectively have the power to vote approximately 12.8% of the outstanding NB&T Financial common shares, entered into a voting agreement with Peoples on August 4, 2014, pursuant to which they agreed, subject to certain terms and conditions, to vote all of their shares in favor of the adoption and approval of the Merger Agreement. No non-director executive officer of NB&T Financial nor any other NB&T Financial shareholder included in the table on page 100 of this joint proxy statement/prospectus has executed a voting agreement with Peoples nor has any such person committed to Peoples or NB&T Financial that such person will vote in favor of any of the matters being presented to the NB&T Financial shareholders at the NB&T Financial special meeting. Excluding such shares held by NB&T Financial directors, the adoption and approval of the Merger Agreement will require the affirmative vote of the holders of at least 1,279,260 NB&T Financial common shares, or 42.6% of the non-committed outstanding shares.

As of the date of this joint proxy statement/prospectus, Peoples and its directors, executive officers and affiliates beneficially owned no NB&T Financial common shares, and NB&T Financial and its directors, executive officers and affiliates beneficially owned no Peoples common shares. Peoples Bank acts as trustee for 555,898 Peoples common shares. NBTC acts as trustee for 460,181 NB&T Financial common shares, 298,780 of which are held as trustee for the ESOP. NBTC will not, though, cast any votes in connection with the Merger with respect to shares held in the ESOP. NBTC has appointed Bankers Trust Company of South Dakota (“Bankers Trust”) to serve as special independent fiduciary of the ESOP in connection with the Merger. Each

participant in the ESOP will have the right to instruct Bankers Trust how to cast the votes attributable to the participant’s allocated shares, and Bankers Trust will have the right to vote in its discretion any shares with respect to which a participant has not provided instruction and any unallocated shares. NBTC will vote the shares it holds as Trustee, other than ESOP shares, with respect to which it has voting power in accordance with its fiduciary duties at the time of the NB&T Financial special meeting, but expects at this time that it will vote the shares in favor of all of the proposals presented for a vote.

Recommendation to NB&T Financial shareholders (page 55)

The board of directors of NB&T Financial unanimously approved the Merger Agreement. The board of directors of NB&T Financial believes that the Merger is in the best interests of NB&T Financial and its shareholders, and, as a result, the directors unanimously recommend that NB&T Financial shareholders vote “FOR” the adoption and approval of the Merger Agreement and “FOR” the proposal to adjourn the special meeting, if necessary and appropriate, to solicit additional proxies.

In reaching this decision, the board of directors of NB&T Financial considered many factors, which are described in the section captioned “THE MERGER—Background of the Merger” and “THE MERGER—NB&T Financial’s Reasons for the Merger” beginning on page 46 and page 54, respectively, of this joint proxy statement/prospectus.

Opinion of NB&T Financial’s Financial Advisor (page 55)

In connection with the Merger, NB&T Financial’s financial advisor, Keefe, Bruyette & Woods, Inc. (“KBW”), delivered a written opinion, dated August 4, 2014, to the NB&T Financial board of directors as to the fairness, from a financial point of view of the merger consideration in the Merger to be received by the holders of NB&T Financial common shares. The full text of the opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW in preparing the opinion, is attached as Annex C to this document. The opinion was for the information of, and was directed to, the NB&T Financial board (in its capacity as such) in connection with its consideration of the financial terms of the Merger. The opinion did not address the underlying business decision of NB&T Financial to engage in the Merger or enter into the Merger Agreement or constitute a recommendation to the NB&T Financial board in connection with the Merger, and it does not constitute a recommendation to any holder of NB&T Financial common shares or any shareholder of any other entity as to how to vote in connection with the Merger or any other matter.

Recommendation to Peoples shareholders (page 68)

The board of directors of Peoples unanimously approved the Merger Agreement. The board of directors of Peoples believes that the Merger is in the best interests of Peoples and its shareholders, and, as a result, the directors unanimously recommend that Peoples shareholders vote “FOR” the adoption and approval of the Merger Agreement, “FOR” the approval of the issuance of up to 3,500,000 commons shares in connection with the Merger, and “FOR” the proposal to adjourn the special meeting, if necessary and appropriate, to solicit additional proxies.

In reaching this decision, the board of directors of Peoples considered many factors which are described in the section captioned “THE MERGER—Background of the Merger” and “THE MERGER—Peoples’ Reasons for the Merger” beginning on page 46 and page 67, respectively, of this joint proxy statement/prospectus.

Opinion of Peoples’ Financial Advisor (page 68)

At the July 24, 2014 meeting of Peoples’ board of directors, Raymond James & Associates, Inc. (“Raymond James”) provided the board with a preliminary overview of certain valuation analyses performed as of the date of the meeting. Raymond James advised the board that its analyses were as of such date and based upon and subject

to various qualifications and assumptions described in the meeting, including the outcome of preliminary due diligence and subject to further review of transaction terms and negotiation. At this meeting the board did not request and Raymond James did not provide an opinion. At the request of Peoples’ board of directors on August 4, 2014, Raymond James rendered its opinion that, as of August 4, 2014, from a financial point of view, the merger consideration to be paid by Peoples pursuant to the Merger Agreement was fair, based upon and subject to the qualifications, assumptions and other matters considered in connection with the preparation of its opinion. The full text of Raymond James’s written opinion, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached to this document as Annex D. The opinion was provided for the information of Peoples’ board of directors (solely in its capacity as such) in connection with, and for purposes of, its consideration of the Merger and the opinion only addressed whether the merger consideration to be paid by Peoples in the Merger pursuant to the Merger Agreement was fair, from a financial point of view, to Peoples. The opinion did not address any other term or aspect of the Merger Agreement or the Merger contemplated thereby. The opinion does not constitute a recommendation to the board or to any holder of Peoples common shares as to how the board, such shareholder or any other person should vote or otherwise act with respect to the Merger or any other matter.

Material U.S. federal income tax consequences of the Merger (page 81)

Peoples and NB&T Financial intend that the Merger will be treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and it is a condition to the obligation of NB&T Financial to complete the Merger that it receives a legal opinion to that effect. If treated as a reorganization, for U.S. federal income tax purposes (i) no gain or loss will be recognized by Peoples or NB&T Financial as a result of the Merger, (ii) NB&T Financial shareholders will recognize gain (but not loss) in an amount not to exceed any cash received in exchange for NB&T Financial common shares in the Merger (other than any cash received in lieu of a fractional Peoples common share, as discussed below under the section entitled “THE MERGER —Material U.S. Federal Income Tax Consequences of the Merger —Cash In Lieu of a Fractional Shares” beginning on page 83) and (iii) NB&T Financial shareholders who exercise dissenters’ rights and receive solely cash in exchange for NB&T Financial common shares in the Merger will recognize gain or loss equal to the difference between the amount of cash received and their tax basis in their shares.

All NB&T Financial shareholders should read carefully the description under the section captioned “THE MERGER —Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 81 of this joint proxy statement/prospectus and should consult their own tax advisors concerning these matters. All NB&T Financial shareholders should consult their tax advisors as to the specific tax consequences of the Merger to them, including the applicability and effect of the alternative minimum tax and any state, local, foreign or other tax laws.

Interests of directors and executive officers of NB&T Financial (page 76)

The directors of NB&T Financial who are not executive officers will receive, in connection with the Merger, the following benefits:

•

continued indemnification to the fullest extent provided by NB&T Financial’s governing documents;

•

coverage under a directors’ and officers’ insurance policy for six years following the effective date of the Merger; and

•

payment in cash equal to $31.00 less the exercise price per share for each NB&T Financial common share subject to a vested or unvested stock option.

In addition, two directors of NB&T Financial will be appointed to the Board of Directors of Peoples and will receive the compensation paid to the other directors of Peoples for service on that Board.

Each executive officer of NB&T Financial will receive:

•

a payment pursuant to an employment or severance agreement as well as continued health, life and disability insurance coverage for a certain period after the consummation of the Merger if the executive officer is terminated by NB&T Financial within six months before, or by Peoples within one year after, the consummation of the Merger, or if the executive officer terminates his employment within one year following the Merger due to certain changes in the circumstances of his employment after the Merger and, in the case of the Chief Executive Officer and President, a non-compete payment;

•

continued indemnification to the fullest extent provided by NB&T Financial’s governing documents;

•

coverage under a directors’ and officers’ insurance policy for six years following the effective date of the Merger; and

•

payment in cash equal to $31.00 less the exercise price per share for each NB&T Financial common share subject to a vested or unvested stock option.

The aggregate dollar value of all of the above described payments and benefits that is actually expected to be received by all directors and executive officers as a group is estimated to equal $5,487,987, based on a number of expectations and assumptions stated in the footnotes to the table on page 76 setting forth all payments expected to be received by the executive officers of NB&T Financial and, with respect to the directors, without attributing any value to continued indemnification or coverage under the directors’ and officers’ liability insurance policy, assuming no options are exercised prior to the closing of the Merger and assuming that the two directors appointed to the board of Peoples receive an aggregate of $65,500 in board fees during their first year after the Merger is consummated, subject to a number of assumptions stated on page 76 of this joint proxy statement/prospectus. The directors will be appointed by Peoples’ Governance and Nominating Committee and voted on at the next annual meeting of the shareholders.

Each of Peoples’ and NB&T Financial’s board of directors was aware of these interests and considered them in approving the Merger Agreement. See “THE MERGER—Interests of NB&T Financial Directors and Executive Officers in the Merger” beginning on page 76 of this joint proxy statement/prospectus.

Dissenters’ rights of NB&T Financial shareholders (page 45)

Under Ohio law, NB&T Financial shareholders who do not vote in favor of the adoption and approval of the Merger Agreement and deliver a written demand for payment for the fair cash value of their NB&T Financial common shares prior to the NB&T Financial special meeting, will be entitled, if and when the Merger is completed, to receive the fair cash value of their NB&T Financial common shares. The right to make this demand is known as “dissenters’ rights.” NB&T Financial shareholders’ right to receive the fair cash value of their NB&T Financial common shares, however, is contingent upon strict compliance with the procedures set forth in Section 1701.85 of the OGCL. An NB&T Financial shareholder’s failure to vote against the adoption and approval of the Merger Agreement will not constitute a waiver of such shareholder’s dissenters’ rights, so long as such shareholder does not vote in favor of the Merger Agreement or return an unmarked proxy card.

For additional information regarding dissenters’ rights, see “DISSENTERS’ RIGHTS” on page 45 of this joint proxy statement/prospectus and the complete text of Section 1701.85 of the OGCL attached to this joint proxy statement/prospectus as Annex B. If NB&T Financial shareholders should have any questions regarding dissenters’ rights, such shareholders should consult with their own legal advisers.

Certain differences in shareholder rights (page 97)

When the Merger is completed, NB&T Financial shareholders (other than those exercising dissenters’ rights) will receive Peoples common shares and, therefore, will become Peoples shareholders. As Peoples shareholders, your rights will be governed by Peoples’ Amended Articles of Incorporation and Regulations, as well as Ohio law. Notably, NB&T Financial shareholders will own less of the combined company and as such will have decreased voting power. Also, while NB&T Financial directors could only be removed for cause and upon the vote of a majority of the shareholders, a Peoples director may be removed with or without cause and only upon the vote of 75% of the shareholders. With respect to the vote to pass actions, certain actions not unanimously approved by the NB&T Financial board required an 80% shareholder vote to pass. As Peoples shareholders, certain actions that are voted against by three or more members of Peoples’ board of directors will require the affirmative vote of 75% of shares entitled to vote. See “COMPARISON OF CERTAIN RIGHTS OF NB&T FINANCIAL AND PEOPLES SHAREHOLDERS” beginning on page 97 of this joint proxy statement/prospectus.

Regulatory approvals required for the Merger (page 76)

The Merger cannot be completed until Peoples receives necessary regulatory approvals, which include the approval of the Federal Reserve and the approval of the OCC. Peoples has received such approval to consummate the Merger from the OCC and the Federal Reserve.

Conditions to the Merger (page 88)

As more fully described in this joint proxy statement/prospectus and in the Merger Agreement, the completion of the Merger depends on the adoption and approval of the Merger Agreement by Peoples’ and NB&T Financial’s shareholders and receipt of the required regulatory approvals, in addition to satisfaction of, or where legally permissible, waiver of, other customary conditions. Although Peoples and NB&T Financial anticipate the closing of the Merger will occur in the first quarter of 2015, neither Peoples nor NB&T Financial can be certain when, or if, the conditions to the Merger will be satisfied or, where permissible, waived, or that the Merger will be completed. See “THE MERGER AGREEMENT—Conditions to Consummation of the Merger” beginning on page 88 of this joint proxy statement/prospectus.

Termination of the Merger Agreement (page 94)

Peoples and NB&T Financial may mutually agree to terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective, whether before or after shareholder approval, if the board of directors of each approves such termination by vote of a majority of the members of its entire board. In addition, either Peoples or NB&T Financial, acting alone, may terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective under the following circumstances:

•

if any of the required regulatory approvals is denied;

•

if the Peoples or NB&T Financial shareholders do not adopt and approve the Merger Agreement at their respective special shareholder meetings;

•

if there is a material breach by the other party of any representation, warranty, covenant or agreement contained in the Merger Agreement that cannot be or has not been cured within 30 days of notice of the breach; or

•

if the Merger has not been consummated by March 31, 2015, unless the failure to complete the Merger by that date is due to the knowing action or inaction of the party seeking to terminate.

Peoples, acting alone, may terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective upon written notice to NB&T Financial if the NB&T Financial board of directors:

•

accepts or agrees to accept a superior acquisition proposal;

•

fails to recommend to the NB&T Financial shareholders in this joint proxy statement/prospectus that they adopt the Merger Agreement;

•

changes NB&T Financial’s recommendation to shareholders, including by publicly approving, endorsing or recommending, or publicly proposing to approve, endorse or recommend, any other acquisition proposal; or

•

fails to comply with its obligations under the Merger Agreement.

NB&T Financial, acting alone, may also terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective upon written notice to Peoples:

•

if NB&T Financial intends to enter into an agreement relating to a superior acquisition proposal in accordance with the terms of the Merger Agreement; or

•

if, prior to the effective time of the Merger and during the time period specified in the Merger Agreement, both the market value of Peoples’ common shares and the NASDAQ Bank Index drop below certain pre-determined thresholds; subject, however, to Peoples’ right to cure by providing notice to NB&T Financial that Peoples intends to proceed with the Merger by paying additional consideration.

Acquisition proposals and termination fee (page 95)

Because NB&T Financial has entered into the Merger Agreement, a binding legal agreement, if (a) Peoples terminates the Merger Agreement due to NB&T Financial’s acceptance of another superior acquisition proposal, failure to recommend to the shareholders adoption of the Merger Agreement, or NB&T Financial’s breach of the voting agreement or the Merger Agreement’s prohibition on solicitation of other acquisition proposals, or (b) NB&T Financial terminates the Merger Agreement with the intention of entering into or accepting an alternate, superior proposal, then, in the case of either (a) or (b) above, NB&T Financial shall pay to Peoples a sum of $4.368 million. See “THE MERGER AGREEMENT—Acquisition Proposals and Termination Fee” beginning on page 95 of this joint proxy statement/prospectus.

The following table summarizes financial results achieved by Peoples for the periods and at the dates indicated and should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” Peoples’ Consolidated Financial Statements and the notes to the Consolidated Financial Statements contained in reports that Peoples has previously filed with the SEC. Historical financial information for Peoples can be found in its Annual Report on Form 10-K for the fiscal year ended December 31, 2013. The information at and for the nine months ended September 30, 2014 and 2013 is unaudited. However, in the opinion of management of Peoples, all adjustments, consisting of normal recurring adjustments necessary for a fair presentation of the results of operations for the unaudited periods have been made. The selected operating data presented below for the nine months ended September 30, 2014 and 2013 are not necessarily indicative of the results that may be expected for future periods.

The information at and for the nine months ended September 30, 2014 and 2013 is unaudited.

You should not assume the results of operations for past periods noted below indicate results for any future period.

The information below has been derived from NB&T Financial’s Consolidated Financial Statements.

The following unaudited pro forma condensed combined financial information for Peoples Bancorp Inc. and Subsidiaries (“Peoples,” for purposes of this section only refers to Peoples Bancorp Inc. and its consolidated subsidiaries collectively, except where the context indicates the reference solely to Peoples Bancorp Inc.) combines the historical consolidated financial position and results of operations of Peoples and NB&T Financial, as an acquisition by Peoples of NB&T Financial using the acquisition method of accounting and giving effect to the related pro forma adjustments described in the accompanying notes. Under the acquisition method of accounting, the assets and liabilities of NB&T Financial will be recorded by Peoples at their respective fair values as of the date the Merger is completed. The pro forma financial information presented should be read in conjunction with Peoples’ Annual Report on Form 10-K for the fiscal year ended December 31, 2013 and Quarterly Report on Form 10-Q for the quarter ended September 30, 2014, and NB&T Financial’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013 and Quarterly Report on Form 10-Q for the quarter ended September 30, 2014.

The unaudited pro forma condensed combined balance sheets give effect to the Merger as if the transaction had occurred on September 30, 2014. The unaudited pro forma condensed combined income statements for the nine months ended September 30, 2014 and year ended December 31, 2013, give effect to the Merger as if the transaction had become effective on January 1, 2014 and January 1, 2013, respectively.

The unaudited pro forma condensed combined financial information included herein is presented for informational purposes only and does not necessarily reflect the financial results of the combined companies had the companies actually been combined at the beginning of the periods presented. The adjustments included in this unaudited pro forma condensed combined financial information are preliminary and may be revised. This information also does not reflect the benefits of the expected cost savings and expense efficiencies, opportunities to earn additional revenue, potential impacts of current market conditions on revenues, or asset dispositions, among other factors, and includes various preliminary estimates and may not necessarily be indicative of the financial position or results of operations that would have occurred if the Merger had been consummated on the date or at the beginning of the period indicated, or which may be attained in the future. The unaudited pro forma condensed combined financial information should be read in conjunction with and is qualified in its entirety by reference to the historical consolidated financial statements and related notes thereto of Peoples, and the historical consolidated financial statements and related notes thereto of NB&T Financial.

The unaudited pro forma condensed combined financial information has been prepared using the acquisition method of accounting, giving effect to the planned Merger of Peoples and NB&T Financial, as if the transaction had occurred as of the beginning of the earliest period presented.

The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of the results of operations or financial position had the Merger been consummated at the beginning of the earliest periods presented, nor is it necessarily indicative of the results of operations in future periods or the future financial position of the combined entities. The Merger, which is currently expected to be completed in the first quarter of 2015, is subject to approval of Peoples’ and NB&T Financial’s shareholders; the satisfaction of various closing conditions, including the receipt of all necessary bank regulatory approvals and the accuracy of the representations and warranties of each party (subject to certain exceptions); the performance in all material respects by each party of its obligations under the Merger Agreement; and other conditions customary for transactions of this type.

The Merger will be accounted for as an acquisition by Peoples using the acquisition method of accounting. Accordingly, the assets and liabilities of NB&T Financial will be recorded at their respective fair values and the values used represent management’s estimates based on available information. The pro forma adjustments included herein are subject to change depending on changes in interest rates and the components of assets and liabilities, additional information that becomes available and additional analysis that is performed. The final allocation of the purchase price will be determined after the Merger is completed and after completion of thorough analysis to determine the fair value of NB&T Financial’s tangible and identifiable intangible assets and liabilities as of the date the Merger. Increases or decreases in the estimated fair values of the net assets, commitments, and other items of NB&T Financial, as compared with the information shown in the unaudited pro forma condensed combined financial information, may change the amount of the purchase price allocated to goodwill and other assets and may impact the statement of income due to adjustments in yield and/or amortization of the adjusted assets or liabilities. Any changes to NB&T Financial’s stockholders’ equity through the date the Merger is completed will also change the purchase price allocation, which may include the recorded value of goodwill. The final adjustments may be materially different from the unaudited pro forma adjustments presented herein.

The pro forma adjustments include the adjustments made to apply acquisition accounting to record the Merger transaction. The excess of the purchase price over the fair value of the net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments included in the pro forma financial statements are based upon available information, and certain assumptions considered reasonable, and may be revised as additional information becomes available. For purposes of this pro forma analysis, fair value adjustments, other than goodwill and adjustments to acquired impaired loans, are amortized/accreted based on the estimated average remaining lives. Tax expense related to the net fair value adjustments is calculated using the statutory tax rate of 35%.

Under the terms of the Merger Agreement, shareholders of NB&T Financial will receive 0.9319 Peoples common share and $7.75 in cash for each NB&T Financial common share. Based upon the volume weighted average closing price of Peoples’ common shares for the twenty trading days ending August 1, 2014, the transaction is valued at $31.00 per share.

The following table summarizes the estimated amortization/accretion of purchase accounting adjustments reflected in the pro forma financial statements on the future pre-tax net income of Peoples after the acquisition of NB&T:

The following pro forma adjustments have been reflected in the unaudited pro forma condensed combined financial information. All taxable adjustments were calculated using a statutory 35% tax rate to arrive at deferred tax asset or liability adjustments. All adjustments are based on current assumptions and/or valuations, which are subject to change.

The following table sets forth for Peoples and NB&T Financial certain historical, pro forma and pro forma-equivalent per share financial information as of and for the year ended December 31, 2013, and as of and for the nine months ended September 30, 2014. The information in the table below, in part, is derived from and should be read together with the historical Consolidated Financial Statements of Peoples and NB&T Financial that are incorporated by reference in this joint proxy statement/prospectus. The unaudited pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect certain anticipated costs and benefits of the Merger and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had the Merger been consummated at the beginning of the periods presented. The pro forma data gives effect to the Merger and is based on numerous assumptions and estimates. The pro forma combined per share data and NB&T Financial equivalent pro forma per share data are prepared assuming a maximum of 3,500,000 common shares will be issued in the Merger. See “THE MERGER AGREEMENT—Merger Consideration” on page 86.

The information presented in the following table reflects the last reported sale prices per share of Peoples’ common shares and NB&T Financial’s common shares as of August 1, 2014, the last trading day preceding our public announcement of the Merger, and on January 21, 2015, the last practicable day for which information was available prior to the date of this joint proxy statement/prospectus. The table also presents the equivalent market value per NB&T Financial common share on August 1, 2014 and January 21, 2015, determined by multiplying the share price of a Peoples common share on such dates by the exchange ratio of 0.9319 and adding the per share cash consideration of $7.75. No assurance can be given as to what the market price of Peoples’ common shares will be if and when the Merger is consummated.

The following table lists the high and low prices per share for Peoples’ common shares and NB&T Financial’s common shares and the cash dividends declared by each company for the periods indicated.

In addition to general investment risks and the other information contained in or incorporated by reference into this joint proxy statement/prospectus, including the matters addressed under the section “FORWARD-LOOKING STATEMENTS” commencing on page 33, you should carefully consider the following risk factors in deciding how to vote for the proposals presented in this joint proxy statement/prospectus. The following is a discussion of the most significant factors that make an investment in Peoples common stock speculative or risky, but does not purport to present an exhaustive description of such risks. You should also consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference into this joint proxy statement/prospectus. See “WHERE YOU CAN FIND MORE INFORMATION” in the forepart of this document.

The market value of Peoples common shares you receive in the Merger may decrease if there are fluctuations in the market price of Peoples’ common shares following the Merger.

Peoples will not issue any fractional shares of common stock in connection with the Merger. Instead, each holder of NB&T Financial common shares who would otherwise be entitled to receive a fraction of a Peoples common share (after taking into account all shares of NB&T Financial common shares owned by such holder at the effective time of the Merger) will receive cash, without interest, in an amount equal to the Peoples fractional common share to which such holder would otherwise be entitled to multiplied by the average closing sale price of a Peoples common share on the NASDAQ for the 10 consecutive trading days immediately preceding the effective date of the Merger.

Any change in the market price of Peoples common shares prior to the completion of the Merger will affect the market value of the merger consideration that NB&T Financial shareholders will receive following completion of the Merger. Stock price changes may result from a variety of factors that are beyond the control of Peoples and NB&T Financial, including but not limited to general market and economic conditions, changes in their respective businesses, operations and prospects and regulatory considerations. Therefore, at the time of the NB&T Financial special meeting, NB&T Financial shareholders will not know the precise market value of the consideration they will receive at the effective time of the Merger. NB&T Financial shareholders should obtain current sale prices for Peoples common shares before voting their shares at the NB&T Financial special meeting.

Peoples could experience difficulties in managing its growth and effectively integrating the operations of NB&T Financial and NBTC, as well as the operations of its recent acquisitions.

Upon consummation of the Merger, Peoples will have completed four bank acquisitions in approximately a twelve-month period. The earnings, financial condition and prospects of Peoples after the Merger will depend in part on Peoples’ ability to integrate successfully the operations of NB&T Financial, NBTC and its prior acquisitions, and to continue to implement its own business plan. Peoples may not be able to fully achieve the strategic objectives and projected operating efficiencies anticipated in the Merger. The costs or difficulties relating to the integration of NB&T Financial, NBTC and the previously acquired banks with the Peoples organization may be greater than expected or the cost savings from any anticipated economies of scale of the combined organization may be lower or take longer to realize than expected. Inherent uncertainties exist in

integrating the operations of any acquired entity, and Peoples may encounter difficulties, including, without limitation, loss of key employees and customers, and the disruption of its ongoing business or possible inconsistencies in standards, controls, procedures and policies. These factors could contribute to Peoples not fully achieving the expected benefits from the Merger.

The Merger Agreement limits NB&T Financial’s ability to pursue alternatives to the Merger with Peoples, may discourage other acquirers from offering a higher valued transaction to NB&T Financial and may, therefore, result in less value for the NB&T Financial shareholders.

The Merger Agreement contains a provision that, subject to certain limited exceptions, prohibits NB&T Financial from soliciting, negotiating, or providing confidential information to any third party relating to any competing proposal to acquire NB&T Financial or NBTC.

In addition, if (a) Peoples terminates the Merger Agreement due to NB&T Financial’s acceptance of another acquisition proposal, failure to recommend to the shareholders adoption of the Merger Agreement, or NB&T Financial’s breach of the voting agreement or the Merger Agreement’s prohibition on solicitation of other acquisition proposals, or, (b) NB&T Financial terminates the Merger Agreement with the intention of entering into or accepting an alternate, superior proposal, then, in the case of either (a) or (b) above, NB&T Financial shall pay to Peoples $4.368 million. The requirement that NB&T Financial make such a payment could discourage another company from making a competing proposal.

The fairness opinions of Peoples’ and NB&T Financial’s respective financial advisors do not reflect changes in circumstances subsequent to the date of such opinions.

Each of the NB&T Financial and Peoples boards of directors received an opinion, dated August 4, 2014, from NB&T Financial’s and Peoples’ respective financial advisor as to the fairness of the merger consideration from a financial point of view as of the date of such opinion. Subsequent changes in the operation and prospects of NB&T Financial or Peoples, general market and economic conditions and other factors that may be beyond the control of NB&T Financial or Peoples may significantly alter the value of NB&T Financial or Peoples or the prices of the shares of NB&T Financial common stock or Peoples common stock by the time the Merger is completed. The opinions do not address the fairness of the merger consideration from a financial point of view at the time the Merger is completed, or as of any other date other than the date of such opinions. The opinion of NB&T Financial’s financial advisor is attached as Annex C to this joint proxy statement/prospectus, and the opinion of Peoples’ financial advisor is attached as Annex D. For a description of the opinions, see “THE MERGER—Opinion of NB&T Financial’s Financial Advisor” on page 55 and “THE MERGER—Opinion of Peoples’ Financial Advisor” on page 68 of this joint proxy statement/prospectus.

Peoples and NB&T Financial shareholders will have a reduced ownership and voting interest after the Merger and will exercise less influence over management of the combined organization.

The Merger will dilute the ownership position of Peoples’ shareholders and result in NB&T Financial’s shareholders having an ownership stake in the combined company that is smaller than their current stake in NB&T Financial. Upon completion of the Merger, we estimate that continuing Peoples shareholders will own approximately 82% of the issued and outstanding common shares of the combined company, and former NB&T Financial shareholders will own approximately 18% of the issued and outstanding common shares of the combined company. Consequently, Peoples shareholders and NB&T Financial shareholders, as a general matter, will have less influence over the management and policies of the combined company after the effective time of the Merger than they currently exercise over the management and policies of Peoples and NB&T Financial, respectively.

Failure to complete the Merger could negatively impact the value of NB&T Financial’s stock and future businesses and financial results of Peoples and NB&T Financial.

If the Merger is not completed, the ongoing businesses of Peoples and NB&T Financial may be adversely affected and Peoples and NB&T Financial will be subject to several risks, including the following:

In addition, if the Merger is not completed, NB&T Financial may experience negative reactions from its customers and employees. Employees could resign and obtain other employment as a result of the potential Merger. NB&T Financial also could be subject to litigation related to any failure to complete the Merger.

The Peoples common shares to be received by NB&T Financial shareholders upon completion of the Merger will have different rights from NB&T Financial common shares.

Upon completion of the Merger, NB&T Financial shareholders will no longer be shareholders of NB&T Financial but will instead become shareholders of Peoples, and their rights as shareholders of Peoples will be governed by the Ohio Revised Code and by Peoples’ Amended Articles of Incorporation and Regulations. The terms of Peoples’ Amended Articles of Incorporation and Regulations are in some respects materially different than the terms of NB&T Financial’s Amended and Restated Articles of Incorporation and Regulations. See “COMPARISON OF CERTAIN RIGHTS OF NB&T FINANCIAL AND PEOPLES SHAREHOLDERS” on page 97 of this joint proxy statement/prospectus.

Completion of the Merger is subject to many conditions and if these conditions are not satisfied or waived, the Merger will not be completed.

The respective obligations of Peoples and NB&T Financial to complete the Merger are subject to the fulfillment or written waiver of many conditions, including approval by the requisite vote of Peoples and NB&T Financial shareholders, respectively, receipt of requisite regulatory approvals, absence of orders prohibiting completion of the Merger, effectiveness of the registration statement of which this document is a part, approval of the Peoples shares to be issued to NB&T Financial for listing on the NASDAQ, the continued accuracy of the representations and warranties by both parties, and the performance by both parties of their covenants and agreements. See “THE MERGER AGREEMENT—Conditions to the Consummation of the Merger” on page 88 of this joint proxy statement/prospectus. These conditions to the consummation of the Merger may not be fulfilled and, accordingly, the Merger may not be completed. In addition, if the Merger is not completed by March 31, 2015, either Peoples or NB&T Financial may have the opportunity to choose not to proceed with the Merger, and the parties can mutually decide to terminate the Merger Agreement at any time, before or after approval by the requisite vote of the NB&T Financial shareholders. In addition, Peoples or NB&T Financial may elect to terminate the Merger Agreement in certain other circumstances. See “THE MERGER AGREEMENT—Termination of the Merger Agreement” on page 94 of this joint proxy statement/prospectus for a fuller description of these circumstances.

Following the Merger, a high percentage of the combined company’s loan portfolio will remain in Ohio, Kentucky and West Virginia and in commercial and residential real estate. Deteriorations in economic conditions in this area or in the real estate market generally could be more harmful to the combined company compared to more diversified institutions.

As of September 30, 2014 approximately $134 million, or 33%, of NB&T Financial’s loan portfolio was comprised of residential real estate loans, and $188 million, or 47%, of NB&T Financial’s loan portfolio was comprised of commercial real estate loans. As of September 30, 2014, approximately $491 million, or 33%, of Peoples’ loan portfolio was comprised of residential real estate loans, and $570 million, or 38%, of Peoples’ loan portfolio was comprised of commercial real estate loans. As a result of the Merger, the combined company’s loan portfolio, as of September 30, 2014, would have consisted of $625 million, or 33%, of residential real estate loans and $758 million, or 40%, of commercial real estate loans.

Inherent risks of commercial real estate (“CRE”) lending include the cyclical nature of the real estate market, construction risk and interest rate risk. The cyclical nature of real estate markets can cause CRE loans to suffer considerable distress. During these times of distress, a property’s performance can be negatively affected by tenants’ deteriorating credit strength and lease expirations in times of softening demand caused by economic deterioration or over-supply conditions. Even if borrowers are able to meet their payment obligations, they may find it difficult to refinance their full loan amounts at maturity due to declines in property value. Other risks associated with CRE lending include regulatory changes and environmental liability. Regulatory changes in tax legislation, zoning, environmental regulation, or similar external conditions that may affect property values and the economic feasibility of existing and proposed real estate projects. Environmental liability as a result of contamination may decrease the real estate collateral’s value or render the collateral worthless. Furthermore, the cost that may be imposed on a responsible borrower for the remediation of a contaminated property may severely impair the borrower’s ability to repay the loan.

The combined company’s CRE loan portfolio will be concentrated in Ohio, Kentucky and West Virginia. There are a wide variety of economic conditions within the local markets of the three states in which most of the combined company’s CRE loan portfolio will be situated. Rates of employment, consumer loan demand, household formation, and the level of economic activity can vary widely from state to state and among metropolitan areas, cities and towns. Metropolitan markets comprise various submarkets where property values and demand can be affected by many factors, such as demographic makeup, geographic features, transportation, recreation, local government, school systems, utility infrastructure, tax burden, building-stock age, zoning and building codes, and available land for development. Despite the Merger, as a result of the continued high concentration of the combined company’s loan portfolio, the combined company may be more sensitive, compared to more diversified institutions, to future disruptions in, and deterioration of, this market, which could lead to losses which could have a material adverse effect on the business, financial condition and results of operations of the combined company.

You should read and consider risk factors specific to Peoples’ business that will also affect the combined company after the Merger, described in Peoples’ Annual Report on Form 10-K for the fiscal year ended December 31, 2013, as updated by subsequently filed Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are filed by Peoples with the SEC and incorporated by reference into this document.

This joint proxy statement/prospectus is being provided to NB&T Financial shareholders in connection with the solicitation of proxies by the NB&T Financial board of directors for use at the special meeting of shareholders to be held at 9:00 am, local time, on March 3, 2015, at 48 North South Street, Wilmington, Ohio 45177, including any adjournments of the special meeting.

This joint proxy statement/prospectus is also being furnished by Peoples to NB&T Financial shareholders as a prospectus in connection with the issuance of Peoples common shares upon completion of the Merger.

At the special meeting, the shareholders of NB&T Financial will be asked to consider and vote upon the following matters:

The board of directors of NB&T Financial believes that the Merger with Peoples is in the best interests of NB&T Financial shareholders and recommends that you vote (1) “FOR” the adoption and approval of the Merger Agreement, (2) “FOR” the approval of the specified compensation, and (3) “FOR” the proposal to adjourn the special meeting of NB&T Financial shareholders, if necessary, to solicit additional proxies.

The board of directors of NB&T Financial has fixed the close of business on January 9, 2015 as the record date for determining the NB&T Financial shareholders who are entitled to notice of and to vote at the NB&T Financial special meeting of shareholders. Only holders of NB&T Financial common shares at the close of business on the record date will be entitled to notice of and to vote at the NB&T Financial special meeting.

As of the close of business on January 9, 2015, there were 3,441,496 NB&T Financial common shares outstanding and entitled to vote at the special meeting. As of the same date, there were no shares of NB&T Financial preferred stock outstanding. The NB&T Financial common shares were held of record by approximately 394 shareholders. Each NB&T Financial common share entitles the holder to one vote on all matters properly presented at the special meeting.

Under NB&T Financial’s Third Amended and Restated Articles of Incorporation, the adoption and approval of the Merger Agreement requires the affirmative vote of the holders of at least a majority of the NB&T Financial common shares outstanding and entitled to vote at the special meeting. Approval of an adjournment of the special meeting requires the affirmative vote of the holders of a majority of NB&T Financial’s common shares represented, in person or by proxy, at the special meeting.

As of January 9, 2015, directors of NB&T Financial owned an aggregate of 441,489 NB&T Financial common shares, an amount equal to approximately 12.8% of the outstanding NB&T Financial common shares. All of the directors of NB&T Financial entered into a voting agreement on such date with Peoples pursuant to which they agreed, subject to certain terms and conditions, to vote all of their shares in favor of the adoption and approval of the Merger Agreement. As of the date of this joint proxy statement/prospectus, Peoples and its directors, executive officers and affiliates beneficially owned no NB&T Financial common shares.

Your vote is important. The adoption and approval of the Merger Agreement requires the affirmative vote of the holders of at least a majority of the NB&T Financial common shares outstanding and entitled to vote at the NB&T Financial special meeting. The proposals to approve the specified compensation and adjournment of the NB&T Financial special meeting, if necessary, to solicit additional proxies require the affirmative vote of at least a majority of the NB&T Financial common shares represented in person or by proxy at the NB&T Financial special meeting. Brokers who hold NB&T Financial common shares in “street name” for the beneficial owners cannot vote these NB&T Financial common shares on any of the three proposals without specific instructions from the beneficial owners. If you fail to return your proxy card or vote in person at the special meeting or if you mark “ABSTAIN” on your proxy card or ballot at the special meeting, or if your NB&T Financial common shares are held in “street name” and you fail to instruct your broker how to vote, it will have the same effect as a vote “AGAINST” the adoption and approval of the Merger Agreement, but will have no effect on the other two proposals.

A quorum, consisting of the holders of a majority of the outstanding NB&T Financial common shares, must be present in person or by proxy at the NB&T Financial special meeting before any action, other than the adjournment of the special meeting, can be taken. A properly executed proxy card marked “ABSTAIN” will be counted for purposes of determining whether a quorum is present.

The NB&T Financial board of directors does not expect any matter other than the adoption and approval of the Merger Agreement, the approval of the specified compensation and, if necessary, the approval of the adjournment of the special meeting to solicit additional proxies, to be brought before the NB&T Financial special meeting. If any other matters are properly brought before the special meeting for consideration, NB&T Financial common shares represented by properly executed proxy cards will be voted, to the extent permitted by applicable law, in the discretion of the persons named in the proxy card in accordance with their best judgment.

A proxy card accompanies each copy of this joint proxy statement/prospectus mailed to NB&T Financial shareholders. Your proxy is being solicited by the board of directors of NB&T Financial. Whether or not you attend the special meeting, the NB&T Financial board of directors urges you to return your properly executed proxy card as soon as possible. If you return your properly executed proxy card prior to the special meeting and do not revoke it prior to its use, the NB&T Financial common shares represented by that proxy card will be voted at the special meeting or, if appropriate, at any adjournment of the special meeting. NB&T Financial’s common shares will be voted as specified on the proxy card or, in the absence of specific instructions to the contrary, will be voted “FOR” the adoption and approval of the Merger Agreement, “FOR” the approval of the specified compensation and, “FOR” the approval of the adjournment of the special meeting, if necessary, to solicit additional proxies.

If you have returned a properly executed proxy card, you may revoke it at any time before a vote is taken at the special meeting by:

Your attendance at the special meeting will not, by itself, revoke your proxy.

If you hold your NB&T Financial common shares in “street name” through a broker, bank or other nominee, you must provide your broker, bank or nominee (the record holder of your shares of common stock) with instructions on how to vote your shares of common stock. Your broker, bank or other nominee will provide you with a proxy card and voting instructions. If you have instructed your broker, bank or other nominee to vote your common shares, you must follow the directions received from your broker, bank or other nominee to change or revoke your vote.

NB&T Financial will bear its own cost of solicitation of proxies on behalf of the NB&T Financial board of directors. Proxies will be solicited by mail, and may be further solicited by additional mailings, personal contact, telephone, facsimile or electronic mail, by directors, officers and employees of NB&T Financial, none of whom will receive additional compensation for their solicitation activities. NB&T Financial has also engaged Alliance Advisors, LLC, a proxy soliciting firm, to assist in the solicitation of proxies for a fee of $6,000, $5.25 per successful telephone contact with a shareholder, $4.75 for a telephone vote received and reimbursement of out-of-pocket expenses. NB&T Financial will also pay the standard charges and expenses of brokerage houses, voting trustees, banks, associations and other custodians, nominees and fiduciaries, who are record holders of NB&T Financial common shares not beneficially owned by them, for forwarding this joint proxy statement/prospectus and other proxy solicitation materials to, and obtaining proxies from, the beneficial owners of NB&T Financial common shares entitled to vote at the special meeting.

If you participate in the NB&T Financial ESOP, you will receive vote authorization forms for the plans that reflect all shares you may direct the special independent fiduciary to vote on your behalf under the plan. Please be aware that the special independent fiduciary of the plan may establish a deadline for submitting your voting instructions that is before the time of the NB&T Financial special meeting.

Under the terms of the NB&T Financial ESOP, the trustee votes all shares held by the NB&T Financial ESOP, but each NB&T Financial ESOP participant may direct the trustee how to vote the common shares allocated to his or her account. The trustee of the NB&T Financial ESOP has delegated all of its rights, responsibilities and authority related to the voting of the NB&T Financial common shares in connection with the Merger to Bankers Trust, in its capacity as special independent fiduciary of the NB&T Financial ESOP. As all NB&T Financial shares held by the NB&T Financial ESOP are allocated to the accounts of participants, Bankers Trust will subject to the exercise of its fiduciary responsibilities, vote all the allocated shares held in the ESOP as instructed by the participants to whom they have been allocated, and vote deemed allocated shares for which timely and complete voting instructions are not received in Bankers Trust’s discretion.

As discussed throughout this joint proxy statement/prospectus, NB&T Financial is asking its shareholders to adopt and approve the Merger Agreement. NB&T Financial shareholders should carefully read this document in its entirety for more detailed information regarding the Merger Agreement and the Merger. In particular, shareholders are directed to the copy of the Merger Agreement attached as Annex A to this joint proxy statement/prospectus.

The board of directors of NB&T Financial recommends a vote “FOR” the approval and adoption of the Merger Agreement.

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended, NB&T Financial is providing the NB&T Financial shareholders with the opportunity to cast an advisory (non-binding) vote on the compensation that may be payable to NB&T Financial’s named executive officers in connection with the Merger, the value of which is set forth in the table included in the section of this document entitled “THE MERGER–Interests of NB&T Financial Directors and Officers in the Merger–Golden Parachute Compensation” on page 80 of this joint proxy/prospectus. NB&T Financial is asking the NB&T Financial shareholders to vote on the approval of the following resolution:

“RESOLVED, that the compensation that may be paid or become payable to the named executive officers of NB&T Financial Group, Inc., in connection with the merger of NB&T Financial Group, Inc., with and into Peoples Bancorp Inc., as disclosed in the table in the section of the joint proxy statement/prospectus entitled “The Merger – Interests of NB&T Financial Directors and Officers in the Merger – Golden Parachute Compensation,” including the associated narrative discussion, is hereby APPROVED.”

The vote on executive compensation payable in connection with the Merger is a vote separate and apart from the vote to approve the Merger. Accordingly, a shareholder may vote to approve and adopt the Merger Agreement and vote not to approve the executive compensation and vice versa. Because the vote is advisory in nature only, it will not be binding on either NB&T Financial or Peoples. Accordingly, because NB&T Financial is contractually obligated to pay the compensation, the compensation will be payable, subject only to the conditions applicable thereto, if the Merger Agreement is approved and adopted and regardless of the outcome of the advisory vote.

The NB&T Financial board of directors recommends a vote “FOR” the NB&T Financial advisory proposal on specified compensation.

The NB&T Financial special meeting may be adjourned to another time or place, if necessary or appropriate, to permit, among other things, the solicitation of additional proxies if there are insufficient votes at the time of the NB&T Financial special meeting to approve and adopt the Merger Agreement. If, at the time of the NB&T Financial special meeting, the number of common shares of NB&T Financial present or represented and voting in favor of the Merger Agreement proposal is insufficient to approve and adopt the Merger Agreement, NB&T Financial intends to move to adjourn the NB&T Financial special meeting in order to enable the NB&T Financial board of directors to solicit additional proxies for approval of the proposal. In that event, NB&T Financial will ask the NB&T Financial shareholders to vote only upon the adjournment proposal and not the merger proposal or the proposal on the specified compensation.

In the NB&T Financial adjournment proposal, NB&T Financial is asking its shareholders to authorize the holder of any proxy solicited by the NB&T Financial board of directors to vote in favor of granting discretionary authority to the proxy holders to adjourn the NB&T Financial special meeting to another time and place for the

purpose of soliciting additional proxies. If the NB&T Financial shareholders approve the adjournment proposal, NB&T Financial could adjourn the NB&T Financial special meeting and any adjourned session of the NB&T Financial special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from NB&T Financial shareholders who have previously voted.

The NB&T Financial board of directors recommends a vote “FOR” the NB&T Financial adjournment proposal.

No other matters are intended to be brought before the NB&T Financial special meeting by NB&T Financial, and NB&T Financial does not know of any matters to be brought before the NB&T special meeting by others. If, however, any other matters properly come before the NB&T Financial special meeting, the persons named in the proxy will vote the shares represented thereby in accordance with their best judgment on any such matter.

This joint proxy statement/prospectus is being provided to Peoples shareholders in connection with the solicitation of proxies by the Peoples board of directors for use at the special meeting of shareholders to be held at 10:00 am, local time, on March 3, 2015, at the Lafayette Hotel, 101 Front Street, Marietta, Ohio 45750, including any adjournments of the special meeting.

At the special meeting, the shareholders of Peoples will be asked to consider and vote upon the following matters:

The board of directors of Peoples believes that the Merger with Peoples is in the best interests of Peoples shareholders and recommends that you vote (1) “FOR” the adoption and approval of the Merger Agreement, (2) “FOR” the approval of the issuance of common shares, and (3) “FOR” the proposal to adjourn the special meeting of Peoples shareholders, if necessary, to solicit additional proxies.

The board of directors of Peoples has fixed the close of business on January 26, 2015, as the record date for determining the Peoples shareholders who are entitled to notice of and to vote at the Peoples special meeting of shareholders. Only holders of Peoples common shares at the close of business on the record date will be entitled to notice of and to vote at the Peoples special meeting.

As of the close of business on January 21, 2015, there were 14,836,735 Peoples common shares outstanding and entitled to vote at the special meeting. As of the same date, there were no shares of Peoples preferred stock outstanding. The Peoples common shares were held of record by approximately 2,420 shareholders. Each Peoples common share entitles the holder to one vote on all matters properly presented at the special meeting.

Under Peoples’ Amended Articles of Incorporation, the adoption and approval of the Merger Agreement, as well as the approval of the issuance of common shares, requires the affirmative vote of the holders of at least a majority of the Peoples common shares outstanding and entitled to vote at the special meeting. Approval of an adjournment of the special meeting requires the affirmative vote of the holders of a majority of Peoples’ common shares represented, in person or by proxy, at the special meeting.

As of January 21, 2015, directors of Peoples owned an aggregate of 381,951 Peoples common shares, an amount equal to approximately 2.6% of the outstanding Peoples common shares. As of the date of this joint proxy statement/prospectus, Peoples and its directors, executive officers and affiliates beneficially owned no NB&T Financial common shares.

Your vote is important. The adoption and approval of the Merger Agreement and the issuance of common shares requires the affirmative vote of the holders of at least a majority of the Peoples common shares outstanding and entitled to vote at the Peoples special meeting. Brokers who hold Peoples common shares in “street name” for the beneficial owners cannot vote these Peoples common shares on the adoption and approval of the Merger Agreement without specific instructions from the beneficial owners. If you fail to vote or if you mark “ABSTAIN” on your proxy card, or if your Peoples common shares are held in “street name” and you fail to instruct your broker how to vote, it will have the same effect as a vote “AGAINST” the adoption and approval of the Merger Agreement.

A quorum, consisting of the holders of a majority of the outstanding Peoples common shares, must be present in person or by proxy at the Peoples special meeting before any action, other than the adjournment of the special meeting, can be taken. A properly executed proxy card marked “ABSTAIN” will be counted for purposes of determining whether a quorum is present.

The Peoples board of directors does not expect any matters other than the adoption and approval of the Merger Agreement, the approval of the issuance of common shares and, if necessary, the approval of the adjournment of the special meeting to solicit additional proxies, to be brought before the Peoples special meeting. If any other matters are properly brought before the special meeting for consideration, Peoples common shares represented by properly executed proxy cards will be voted, to the extent permitted by applicable law, in the discretion of the persons named in the proxy card in accordance with their best judgment.

A proxy card accompanies each copy of this joint proxy statement/prospectus mailed to Peoples shareholders. Your proxy is being solicited by the board of directors of Peoples. Whether or not you attend the special meeting, the Peoples board of directors urges you to return your properly executed proxy card as soon as possible. If you return your properly executed proxy card prior to the special meeting and do not revoke it prior to its use, the Peoples common shares represented by that proxy card will be voted at the special meeting or, if appropriate, at any adjournment of the special meeting. Peoples’ common shares will be voted as specified on the proxy card or, in the absence of specific instructions to the contrary, will be voted “FOR” the adoption and approval of the Merger Agreement, “FOR” the approval of the issuance of common shares and “FOR” the approval of the adjournment of the special meeting, if necessary, to solicit additional proxies.

If you have returned a properly executed proxy card, you may revoke it at any time before a vote is taken at the special meeting by:

Your attendance at the special meeting will not, by itself, revoke your proxy.

If you hold your Peoples common shares in “street name” through a broker, bank or other nominee, you must provide your broker, bank or nominee (the record holder of your shares of common stock) with instructions on how to vote your shares of common stock. Your broker, bank or other nominee will provide you with a proxy card and voting instructions. If you have instructed your broker, bank or other nominee to vote your common shares, you must follow the directions received from your broker, bank or other nominee to change or revoke your vote.

Peoples will bear its own cost of solicitation of proxies on behalf of the Peoples board of directors. Proxies will be solicited by mail, and may be further solicited by additional mailings, personal contact, telephone,

facsimile or electronic mail, by directors, officers and employees of Peoples, none of whom will receive additional compensation for their solicitation activities. Peoples has also engaged Georgeson, Inc., a proxy soliciting firm, to assist in the solicitation of proxies for a fee of $7,500, $6.00 per successful telephone contact with a shareholder, $4.00 for a telephone vote received and reimbursement of reasonable out-of-pocket expenses. Peoples will also pay the standard charges and expenses of brokerage houses, voting trustees, banks, associations and other custodians, nominees and fiduciaries, who are record holders of Peoples common shares not beneficially owned by them, for forwarding this joint proxy statement/prospectus and other proxy solicitation materials to, and obtaining proxies from, the beneficial owners of Peoples common shares entitled to vote at the special meeting.

As discussed throughout this joint proxy statement/prospectus, Peoples is asking its shareholders to adopt and approve the Merger Agreement. Peoples shareholders should read this document carefully in its entirety for more detailed information regarding the Merger Agreement and the Merger. In particular, shareholders are directed to the copy of the Merger Agreement attached as Annex A to this joint proxy statement/prospectus.

The board of directors of Peoples recommends a vote “FOR” the approval and adoption of the Merger Agreement.

Peoples is also asking its shareholders to consider and vote on the proposal to issue up to 3,500,000 Peoples common shares in connection with the Merger. If Peoples shareholders fail to approve the issuance of Peoples common shares, the Merger cannot be completed. Peoples shareholders should carefully read this joint proxy statement/prospectus in its entirety, including the annexes, for more detailed information concerning the Merger Agreement and the Merger. A copy of the Merger Agreement is attached to this joint proxy statement/prospectus as Annex A.

NASDAQ Shareholder Voting Rules. Under the NASDAQ Stock Market Rules, a company listed on the NASDAQ is required to obtain shareholder approval prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, in any transaction or series of related transactions if the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the common stock or of securities convertible into or exercisable for common stock. In order to complete the Merger, Peoples will need to issue common shares in excess of 20% of the number of common shares currently outstanding. For this reason, Peoples must obtain the approval of Peoples shareholders for the issuance of Peoples common shares in order to complete the Merger.

The board of directors of Peoples recommends that its shareholders vote “FOR” the proposal to approve the issuance of up to 3,500,000 Peoples common shares in connection with the Merger.

The Peoples special meeting may be adjourned to another time or place, if necessary or appropriate, to permit, among other things, the solicitation of additional proxies if there are insufficient votes at the time of the Peoples special meeting to approve and adopt the Merger Agreement and the issuance of common shares. If, at the time of the Peoples special meeting, the number of common shares of Peoples present or represented and voting in favor of the Merger Agreement proposal is insufficient to approve and adopt the Merger Agreement and the issuance of common shares, Peoples intends to move to adjourn the Peoples special meeting in order to enable the Peoples board of directors to solicit additional proxies for approval of the proposal. In that event, Peoples will ask the Peoples shareholders to vote only upon the adjournment proposal and not the Merger proposal or the proposal on the issuance of common shares.

In the Peoples adjournment proposal, Peoples is asking its shareholders to authorize the holder of any proxy solicited by the Peoples board of directors to vote in favor of granting discretionary authority to the proxy holders to adjourn the Peoples special meeting to another time and place for the purpose of soliciting additional proxies. If the Peoples shareholders approve the adjournment proposal, Peoples could adjourn the Peoples special meeting and any adjourned session of the Peoples special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Peoples shareholders who have previously voted.

The Peoples board of directors recommends a vote “FOR” the Peoples adjournment proposal.

No other matters are intended to be brought before the Peoples special meeting by Peoples, and Peoples does not know of any matters to be brought before the Peoples special meeting by others. If, however, any other matters properly come before the Peoples special meeting, the persons named in the proxy will vote the shares represented thereby in accordance with their best judgment on any such matter.

Shareholders of NB&T Financial are entitled to certain dissenters’ rights pursuant to Sections 1701.84(A) and 1701.85 of the OGCL. Section 1701.85 generally provides that shareholders of NB&T Financial will not be entitled to such rights without strict compliance with the procedures set forth in Section 1701.85, and failure to take any one of the required steps may result in the termination or waiver of such rights. Specifically, any NB&T Financial shareholder who is a record holder of NB&T Financial common shares on January 9, 2015, the record date for the NB&T Financial special meeting and whose shares are not voted in favor of the adoption of the Merger Agreement may be entitled to be paid the “fair cash value” of such NB&T Financial common shares after the effective time of the Merger. To be entitled to such payment, a shareholder must deliver to NB&T Financial a written demand for payment of the fair cash value of the shares held by such shareholder, before the vote on the Merger proposal is taken, the shareholder must not vote in favor of approval and adoption of the Merger Agreement, and the shareholder must otherwise comply with Section 1701.85. An NB&T Financial shareholder’s failure to vote against the adoption and approval of the Merger Agreement will not constitute a waiver of such shareholder’s dissenters’ rights. Any written demand must specify the shareholder’s name and address, the number and class of shares held by him, her or it on the NB&T Financial record date, and the amount claimed as the “fair cash value” of such NB&T Financial common shares. See the text of Section 1701.85 of the OGCL attached as Annex B to this joint proxy statement/prospectus for specific information on the procedures to be followed in exercising dissenters’ rights.

If NB&T Financial so requests, dissenting shareholders must submit their share certificates to NB&T Financial within 15 days of such request, for endorsement on such certificates by NB&T Financial that a demand for appraisal has been made. Failure to comply with such request will terminate the dissenting shareholders’ rights. Such certificates will be promptly returned to the dissenting shareholders by NB&T Financial. If NB&T Financial and any dissenting shareholder cannot agree upon the “fair cash value” of NB&T Financial’s common shares, either may, within three months after service of demand by the shareholder, file a petition in the Court of Common Pleas of Clinton County, Ohio, for a determination of the “fair cash value” of such dissenting shareholder’s NB&T Financial common shares. The fair cash value of an NB&T Financial common share to which a dissenting shareholder is entitled to under Section 1701.85 will be determined as of the day prior to the vote of the NB&T Financial shareholders. If the common shares of NB&T Financial are listed on a national securities exchange, such as the NASDAQ, immediately before the effective time of the Merger, the fair cash value will be the closing sale price of NB&T Financial’s common shares as of the close of trading on the day before the vote of the NB&T Financial shareholders. Investment banker opinions to company boards of directors regarding the fairness from a financial point of view of the consideration payable in a transaction such as the Merger are not opinions regarding, and do not address, “fair cash value” under Section 1701.85.

If an NB&T Financial shareholder exercises his or her dissenters’ rights under Section 1701.85, all other rights with respect to such shareholder’s NB&T Financial common shares will be suspended until NB&T Financial purchases the shares, or the right to receive the fair cash value is otherwise terminated. Such rights will be reinstated should the right to receive the fair cash value be terminated other than by the purchase of the shares.

The foregoing description of the procedures to be followed in exercising dissenters’ rights available to holders of NB&T Financial’s common shares pursuant to Section 1701.85 of the OGCL may not be complete and is qualified in its entirety by reference to the full text of Section 1701.85 attached as Annex B to this joint proxy statement/prospectus.

The Merger Agreement provides for the merger of NB&T Financial with and into Peoples (the “Merger”), with Peoples as the surviving entity. Thereafter, at a later time specified by Peoples Bank in its certificate of merger filed with the OCC, NBTC will be merged with and into Peoples Bank, with Peoples Bank surviving the subsidiary bank merger.

The Merger Agreement is attached to this joint proxy statement/prospectus as Annex A and is incorporated in this joint proxy statement/prospectus by reference. You are encouraged to read the Merger Agreement carefully, as it is the legal document that governs the Merger.

The board of directors of NB&T Financial has from time-to-time explored and assessed various options potentially available to NB&T Financial to increase NB&T Financial’s shareholder value. Over the past several years, these strategic discussions included growing concerns over NB&T Financial’s profitability in an environment of increasing consolidation and competition in the financial institutions industry, increasing regulatory compliance and oversight expense, rapidly changing technology, low interest rates and shrinking margins, inconsistent loan demand and general economic uncertainty. In addition, the directors have remained mindful of the limited liquidity of NB&T Financial’s common shares, and the fact that any need or desire by a large shareholder to sell a substantial number of shares in a short period of time could depress the price of the common shares and harm many smaller shareholders in the process.

In 2009, NB&T Financial acquired by merger Community National Corporation and its subsidiary, Community National Bank (“CNB”). CNB had $59.2 million in loans and $75.5 million in deposits, compared to $329.2 million in loans and $465.9 million in deposits of NB&T Financial at that time. This transaction was immediately accretive to NB&T Financial’s capital. The CNB acquisition added five branches to NB&T Financial which were geographically complementary to existing offices. NB&T Financial later closed one of these offices and sold the facility.

In March 2010, NB&T Financial further benefitted from the opportunity to acquire certain assets and deposit liabilities of American National Bank (“ANB”) when ANB failed and the FDIC was appointed as the receiver. This transaction added $5.0 million to NB&T Financial’s capital, although it later closed the office it acquired in the transaction and sold the facility.

Those two acquisitions boosted NB&T Financial’s size and profitability, but the board of directors believed that additional size would be necessary to achieve the economies of scale that would allow it to remain profitable in the face of increasing regulatory compliance and technology costs and tight interest margins. Other acquisition opportunities that the board of directors believed would be beneficial to NB&T Financial and its shareholders have, however, been limited for the last several years.

Although NB&T Financial submitted several indications of interest in acquiring other financial institutions since the acquisition of ANB, it ultimately could not outbid larger financial institutions. When compared to the institutions with which it has competed for acquisition opportunities, the low trading volume and relatively low market price in relation to book value of NB&T Financial’s shares have been an obstacle. In 2013, NB&T Financial and a smaller bank negotiated an agreement almost to execution before the other institution terminated negotiations, citing a decline in the market price of NB&T Financial’s common shares. The decline in price was not unusual given that only a few trades can significantly lower the price due to the low trading volume in NB&T Financial’s common shares.

While attempting to find desirable acquisitions, NB&T Financial’s management focused on attempting to increase revenue, originate more quality loans, decrease expenses and generally continue to operate NB&T

Financial in a safe and sound manner. One idea considered to decrease expenses was to terminate the registration

of NB&T Financial’s common shares with the SEC, thus reducing SEC compliance expense. The board concluded, however, that deregistration would make acquisitions of other financial institutions even more difficult because NB&T Financial shares would cease to be viable deal currency and might further decrease the already low trading volume in NB&T Financial’s common shares.

Despite NB&T Financial’s efforts to become more profitable while remaining independent, its results were mixed. Following the ANB acquisition, NB&T Financial’s earnings were relatively flat for three years, ranging from $3.8 million to $4.2 million during that period. Moreover, even when NB&T Financial reported favorable quarterly financial results, the market price of NB&T Financial’s common shares was largely unaffected due to thin trading and a lack of analyst coverage.

At its meeting on January 21, 2014, the board of directors decided to invite representatives of three investment banking firms, including KBW, to attend the February 18, 2014, board meeting. At the February 18, 2014 meeting, the invited firms discussed with the directors their investment banking qualifications and provided preliminary feedback regarding potential strategic and financial alternatives that might be available to NB&T Financial. These alternatives included, among others, methods to promote intrinsic growth, potential acquisitions or other forms of expansion by NB&T Financial and a process to sell the company. The board also discussed and asked questions of the investment bankers regarding the positive and negative implications of the options discussed.

Representatives of Vorys, Sater, Seymour and Pease LLP (“Vorys”), NB&T Financial’s legal counsel, reviewed with the directors their fiduciary duties generally and specifically in the context of strategic planning. The directors then discussed the presentations that were made and the feedback received from the three investment banks regarding various potential alternatives that the board might explore, including a potential process to sell the company, and particularly, the possibility NB&T Financial’s trading price might not increase meaningfully, if at all, for some time if NB&T Financial remained independent. The board further discussed that if the proposed bids fell short of expectations, the process could be stopped.

Lastly, the board decided to engage KBW as NB&T Financial’s financial advisor. Mr. Limbert informed KBW of the board’s decision to retain KBW as NB&T Financial’s its financial advisor later that day.

The board of directors of NB&T Financial met next on March 18, 2014. At this meeting, the directors discussed at length the investment bankers’ feedback at the February 18 meeting. They also discussed the following matters:

After the discussion, Mr. Limbert was asked to inform KBW that the board would like to start the process of soliciting indications of interest in a sale of the company directed to a targeted number of appropriate prospective purchasers. Following the meeting, Mr. Limbert communicated the board’s request to KBW.

Between March 24, 2014 and April 22, 2014, Mr. Limbert had numerous discussions with KBW to review and discuss the various companies that could be potentially interested acquirers.

NB&T Financial’s board next met on April 22, 2014. At this meeting, with Vorys present, the board of directors discussed potential acquirers. The directors scheduled a meeting on April 24, 2014, to further discuss potential acquirers with KBW.

On April 24, 2014, the board met telephonically, with KBW and Vorys participating. KBW discussed with the directors the companies that could be contacted to determine whether they would be interested in reviewing information about NB&T Financial. The locations, financial performance metrics, acquisition history and other information regarding the prospective bidders were discussed. At the conclusion of the meeting, the directors asked KBW to provide to the directors additional information about one of the companies, and authorized KBW to contact and send confidentiality agreements to 12 companies. Subsequent to the April 24^th board meeting, NB&T Financial authorized KBW to contact four additional companies. As part of the process, after companies signed confidentiality agreements, they would be told that the potential seller was NB&T Financial and they would be invited to access a data room with information about NB&T Financial. Between May 12, 2014, and June 15, 2014, NB&T Financial posted numerous documents on the data site.

Between April 25, 2014 and the initial due date for letters of interest of May 28, 2014, KBW contacted the 16 companies. Those companies that executed confidentiality agreements were granted access to the secure virtual data room. During this time the companies conducted due diligence in preparation for submitting an initial letter of interest.

Beginning in early May, NB&T Financial began posting in the virtual data room various information for review by potential bidders, including financial information, credit file summaries, problem loan analysis, loan loss allowance calculation and documentation, and internal and external audit reports.

The board met again on May 20, 2014, with KBW and Vorys present. At this meeting, the board discussed which companies had signed confidentiality agreements, which remained interested after learning that NB&T Financial was the prospective seller, and the status of certain prospective acquirers in reviewing materials on the online data room. The directors also discussed additional companies that may have an interest in considering a transaction with NB&T Financial.

On May 30, 2014, NB&T Financial’s board of directors met to review the indications of interest that had been received to date. KBW informed the board that 16 companies had been contacted, 13 of them signed confidentiality agreements and seven submitted indications of interest. KBW reviewed the details of the indications with the board, such as price, form of consideration, termination fees, contingencies to completing the transaction, walkaway rights, anticipated branch closings and effect on employees and discussed the bidder’s financial ability to potentially increase its stated price. The directors also offered their insight and knowledge of the bidders throughout the discussion. Given the significant gap between the three highest bids and the other indications, the board decided to invite the three highest bidders to conduct further due diligence on NB&T Financial, including loan file review and meetings with NB&T Financial’s management.

On June 2, 2014, at the board’s direction, KBW contacted each of the three bidders and informed them of the board’s decision to invite such bidder to conduct further due diligence. KBW requested each of the three companies to provide a list of additional due diligence items. KBW also informed each company they would have an opportunity to conduct interviews with select members of management. A final due date for revised letters of interest was set for June 27, 2014.

Once each company submitted its additional due diligence request list, NB&T Financial’s management team began gathering documents and populating folders within the virtual data room specific to each company addressing the requested items. In addition, each company was provided remote, electronic access to NB&T Financial’s loan documents. Each company continued to conduct electronic due diligence up to the revised bid date of June 27, 2014.

On June 10, 2014, NB&T Financial’s management, along with KBW, met off-site with management of one of the final three bidders. This meeting addressed the various operating units of NB&T Financial and how policies, procedures and infrastructure could come together in the event of a possible acquisition.

On June 12, 2014, management of NB&T Financial and Peoples met off-site with KBW in attendance. These discussions centered around possible synergies between the various units of Peoples and NB&T Financial.

On June 13, 2014, management of NB&T Financial and KBW met off-site with the third potential bidder. Similar to the meeting with other bidders, this meeting focused on how the various operating units, policies, procedures and infrastructure of NB&T and the bidder could come together.

At its meeting on June 17, 2014, the board discussed the upcoming meetings of the directors with each of the three final bidders, at which time each bidder would describe itself and why NB&T Financial should pursue a transaction with such bidder. KBW updated the board on the status of diligence that had been conducted to date by the three parties, and Mr. Limbert and Craig F. Fortin, NB&T Financial’s Chief Financial Officer, gave their impressions of the diligence that had been conducted so far. The meeting concluded with KBW discussing the potential steps of the process going forward, including NB&T Financial selecting a final bidder, negotiating an agreement and conducting reverse due diligence on the buyer.

On June 18, 2014, NB&T Financial’s management and KBW held a follow up meeting off-site with management of one of the bidders. The purpose of this meeting was for the potential bidder to become better familiar with the NB&T Financial’s management and determine their strengths and weaknesses should they be the winning bidder. Additionally, NB&T Financial wanted to learn more about the possible acquisition candidate and its business.

On June 23, 2014, the board of directors had separate meetings off-site with representatives of each of the three companies that had conducted on-site due diligence. Representatives of KBW and Vorys were also present. Each company, including Peoples, provided information about the company as well as its plans for the combined company after the consummation of the proposed merger. The directors, KBW and Vorys asked questions and received answers. Each of the prospective buyers indicated that it would submit its final indication of interest within a few days of the meeting. During Peoples’ presentation, Peoples and the directors discussed Peoples’ plans to sell common shares to raise capital in order to fund the cash portion of the proposed merger consideration. Each of the three companies submitted final indications of interest to KBW on June 27, 2014, which were forwarded to the directors of NB&T Financial.

The directors considered that the three indications of interest had much in common, as discussed above, and all three potential buyers offered certain similar advantages to the NB&T Financial shareholders, including increased stock liquidity and a buyer with sufficient size to better bear the costs of increasing regulatory burdens. The proposed cash-out of all unexercised stock options was included in all three indications of interest and was consistent with the provisions of the option awards providing that all unvested options would immediately vest upon a change in control of NB&T Financial. Moreover, the cashing out of options was administratively easier for the acquiring company than paying the value of the options in a combination of stock and cash.

The board next met on July 2, 2014. After reviewing its fiduciary duties to the shareholders, the board reviewed, considered and discussed whether the directors still believed it was in the best interests of NB&T Financial and its shareholders to continue to pursue a sale of the company. They discussed the various obstacles to staying independent and to future growth, and the return that could be provided to the shareholders from remaining independent compared to the return from a sale of the company. After concluding that a sale was in the best interests of the shareholders, KBW reviewed with the board each of the final indications of interest. The directors discussed at length the details of each proposal, including, among other things, the price and form of consideration, conditions to closing, liquidity of bidder stock, financial performance of the bidders and analysts’ reviews, expectations for future price increases in bidder stock, likelihood of obtaining regulatory approval for the transaction, and the experience and thoughts of management and directors on each of the bidders.

All three indications of interest contemplated a merger of NB&T Financial into the buyer followed by the merger of NBTC into the buyer’s subsidiary bank, as well as:

The indication of interest from the second alternative company (“Company B”) included:

The above described terms constitute all of the material terms of each of the indications of interest as of June 27, 2014.

The board considered that, although the value of the consideration offered in the indications of interest would range from $30.00 to $31.00, at the time of receipt of revised indications of interest on June 27, 2014, the implied market value of the consideration would fluctuate between deciding to move ahead with a select company, the signing of the merger agreement and ultimately the closing of the transaction due to changes in the market price of the buyer’s stock between signing and closing. An average market price for each company would ultimately be used to set the exchange ratio at the time of signing the definitive merger agreement. Thus, anticipated changes in the price of each bidder’s stock between signing and closing, as well as expectations of performance after the closing, were important considerations for the directors in determining which of the three proposals represented the best transaction.

The directors further considered, though, that there were certain advantages to the Peoples proposal over the other two, in addition to the higher price at the time of signing the definitive agreement. Such advantages included:

The board believed that Peoples’ common stock was likely to increase in value to a greater extent than the stock of the other two potential buyers based on a comparison of the financial performance of the three companies, their stock prices at that time and expectations of the future prices of their stock published by multiple stock research firms. The directors also believed that Peoples would agree to some of the provisions in the indications of interest of the other two potential buyers that were not mentioned in Peoples’ proposal, including the provision of retention bonuses and a termination right for NB&T Financial in the event of a substantial drop in the market price of Peoples common stock between execution of the merger agreement and the closing.

The Board did not advise any of the potential buyers of the material terms of the other indications of interest. Neither Company A nor Company B was given an opportunity to increase its proposed merger consideration as they were told that their final indications of interest must include their best offers.

Following this discussion, the directors unanimously decided to negotiate a transaction with Peoples. Later that day, at the board’s direction, KBW informed Peoples that NB&T Financial’s board had selected it as the successful bidder and informed the others they had not been selected. Additionally, KBW requested that Peoples begin drafting the definitive merger agreement.

On July 3, 2014, on behalf of NB&T Financial, KBW submitted to Peoples a list of documents requested by NB&T Financial as part of NB&T Financial’s diligence. Documents provided by Peoples were reviewed, and on July 8, 2014, management of NB&T Financial, KBW and Vorys met with management of Peoples at Peoples’ main office to review documents and obtain additional information. Between July 8, 2014 and the signing of the Merger Agreement, Raymond James and KBW continued to have discussions surrounding the status of Peoples’ proposed private placement capital raise. On July 11, 2014, as part of its regular executive management committee meeting, management discussed their due diligence review and noted no significant concerns.

The board met next on July 15, 2014, with KBW and Vorys present by phone. Management, KBW and Vorys updated the directors on the status of negotiations with Peoples and the proposed timing of signing the definitive agreement.

On July 16, 2014, Dinsmore & Shohl LLP (“Dinsmore”), counsel for Peoples, sent to Vorys an initial draft of the proposed merger agreement. Between July 16 and July 22, 2014, management, Vorys and KBW reviewed and discussed the draft agreement. On July 22, 2014, Vorys provided a revised merger agreement to management of NB&T Financial, which distributed it to the directors.

On July 23, 2014, legal counsel for NB&T Financial and Peoples discussed what appeared to be the larger issues still to be addressed in the merger agreement, including employee retention bonuses pending closing and conversion, post-closing employee benefits and severance and certain covenants and representations of the parties. NB&T Financial and Peoples agreed on the importance of retention bonuses in order to encourage key personnel of NB&T Financial to remain employed with NB&T Financial and then Peoples through the merger and the integration of NB&T Financial’s systems into Peoples’ systems. In addition, the details of terminating NB&T Financial’s employee benefit plans and the coverage of NB&T Financial employees and covered retirees under Peoples’ benefit plans required discussion in the Merger Agreement in order to ensure a smooth transition and fair treatment of such persons and to be able to explain the benefits to them after announcement of the merger. NB&T Financial’s directors are permitted by Ohio law to consider the interests of NB&T Financial’s employees and other constituencies in negotiating the terms of a merger. The benefits to be provided to NB&T Financial’s employees after the merger would be important in retaining employees for the benefit of the resulting company and its shareholders. It was also important for obtaining the votes of employees on the transaction, as employee are also shareholders. The directors also recognized the importance of having NB&T Financial director representation on the Board of Directors of Peoples in order to provide insight into the market areas served by NB&T Financial, in which Peoples did not have any presence, and to provide employees and customers of NB&T Financial some assurance that their interests would be represented on the board of directors of Peoples after the closing of the Merger. Later that day, Vorys sent a revised merger agreement to Peoples.

On July 25, 2014, executives of Peoples and NB&T Financial met in Columbus, Ohio to discuss potential personnel alignments following a transaction. They also discussed briefly the private placement that Peoples would be undertaking to raise capital to pay the cash portion of the purchase price for NB&T Financial.

On July 28, 2014, Dinsmore returned to Vorys a further revised merger agreement, which was forwarded to the directors and management of NB&T Financial.

The board met again on July 29, 2014 to discuss the status of the negotiation of the merger agreement. Vorys reviewed the current draft with the directors and summarized the remaining substantive issues, which included the appointment of directors to Peoples’ board, and the potential advisability of an advisory board. The board then set a meeting date on August 4, 2014 to review and approve the merger agreement.

On July 30 and 31, 2014, Vorys and Dinsmore discussed remaining questions and differences in the drafts provided by each party to the merger agreement. These included, along with other undisputed drafting matters,

revisions with respect to the Peoples capital raise, third-party agreements of each party, the payment of dividends on NB&T Financial common shares before closing, and the ability of Peoples to close the transaction without the proposed capital raise. Counsel for both parties also continued to negotiate various changes with respect to employee benefits following the proposed merger. Dinsmore sent a revised version of the merger agreement to Vorys and NB&T Financial on July 31, 2014.

Between July 8, 2014, and August 1, 2014, at NB&T Financial’s direction, KBW discussed with Raymond James NB&T Financial’s right to terminate the merger agreement if the market price of Peoples’ common shares decreased a certain extent prior to closing and Peoples did not increase the exchange ratio. The market price of Peoples common shares had fallen during the period during which the exchange ratio would be set. NB&T Financial wanted the right to terminate with a smaller decrease in Peoples’ stock price between signing and closing, to which Peoples agreed on August 1, 2014.

On August 1, 2014, Raymond James provided to KBW, which KBW forwarded to NB&T Financial and Vorys, materials regarding Peoples’ capital raise. Between August 2 and August 4, 2014, Vorys provided to Dinsmore revised versions of NB&T Financial’s disclosure schedule.

On August 4, 2014, the board of NB&T Financial met with Vorys and KBW to consider the proposed definitive merger agreement. Vorys reported to the board on the status of People’s private placement to raise capital for the cash portion of the proposed purchase price, including the substance of the private placement documents and the offering price per share. KBW also reported on the status of the private placement.

The directors then reviewed, considered and discussed in detail the proposed definitive agreement. Among the items discussed were the financial terms, the limitations on alternative acquisition proposals following signing the agreement, termination provisions and when a termination fee would be payable. Management then updated the board on due diligence that had been conducted on Peoples by NB&T Financial.

At this meeting, KBW reviewed the financial aspects of the proposed merger and verbally rendered to the board an opinion (which was confirmed later that day by a written opinion dated August 4, 2014) to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by KBW as set forth in such opinion, the merger consideration in the proposed merger was fair, from a financial point of view, to the holders of NB&T Financial common shares. See “THE MERGER—Opinion of NB&T Financial’s Financial Advisor” on page 55.

KBW was then excused from the meeting and the directors proceeded to discuss the merger agreement. The directors proceeded to discuss those considerations that they believed to be necessary or appropriate to enable the board to reach an informed decision as to the fairness and advisability of the merger, including various considerations that it believed supported a decision to approve the merger agreement and recommend its adoption to NB&T Financial’s shareholders, as well as a number of negative considerations. These considerations are discussed below under the heading “THE MERGER—NB&T Financial’s Reasons for the Merger” on page 54. The directors then unanimously determined that the terms of the merger agreement, including the consideration to be paid to NB&T Financial shareholders pursuant to the merger, were fair to, and the merger was advisable and in the best interests of, NB&T Financial and its shareholders.

The board unanimously adopted and approved the Merger Agreement, authorized Mr. Limbert to execute and deliver it, and directed that the Merger Agreement be submitted for consideration and adoption and approval by NB&T Financial’s shareholders at a special meeting. Following the board meeting, NB&T Financial and Peoples finalized, executed and delivered copies of the Merger Agreement. Additionally, the members of NB&T Financial’s board of directors signed a voting agreement obligating them to vote their shares in favor of the adoption of the Merger Agreement. The form of voting agreement is attached as Exhibit A to the Merger Agreement, which is included as Annex A to this joint proxy statement/prospectus. The parties issued a joint press release announcing the Merger following the close of the market on August 4, 2014, and filed Forms 8-K disclosing the Merger Agreement and its terms.

NB&T Financial’s board of directors determined that the Merger and the merger consideration were in the best interests of NB&T Financial and its shareholders and recommends that NB&T Financial shareholders vote in favor of the approval and adoption of the Merger Agreement.

In its deliberations and in making its determination, NB&T Financial’s board of directors considered many factors, including, without limitation, the following:

The above discussion of the information and factors considered by NB&T Financial’s board of directors is not intended to be exhaustive, but includes all material factors considered by the board in arriving at its determination to approve, and to recommend that the NB&T Financial shareholders vote to approve the Merger Agreement. The NB&T Financial board of directors did not assign any relative or specific weights to the above factors, and individual directors may have given differing weights to each factor.

NB&T Financial engaged Keefe, Bruyette & Woods, Inc. (“KBW”) to render financial advisory and investment banking services to NB&T Financial, including an opinion to the NB&T Financial board of directors as to the fairness, from a financial point of view, to the holders of NB&T Financial common shares, of the merger consideration in the proposed merger of NB&T Financial with and into Peoples. NB&T Financial selected KBW because KBW is a nationally recognized investment banking firm with substantial experience in transactions similar to the Merger and familiarity with NB&T Financial. As part of its investment banking business, KBW is continually engaged in the valuation of financial services businesses and their securities in connection with mergers and acquisitions.

As part of its engagement, representatives of KBW attended the meeting of the NB&T Financial board held on August 4, 2014, at which the NB&T Financial board evaluated the proposed merger. At this meeting, KBW reviewed the financial aspects of the proposed merger and rendered an opinion to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW as set forth in such opinion, the merger consideration in the proposed merger was fair, from a financial point of view, to the holders of NB&T Financial common shares. The NB&T Financial board approved the Merger Agreement at this meeting.

The description of the opinion set forth herein is qualified in its entirety by reference to the full text of the opinion, which is attached as Annex C to this joint proxy statement/prospectus and is incorporated herein by reference, and describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW in preparing the opinion. KBW has consented to the inclusion of its opinion letter as Annex C to this joint proxy statement/prospectus.

KBW’s opinion speaks only as of the date of the opinion. The opinion was for the information of, and was directed to, the NB&T Financial board (in its capacity as such) in connection with its consideration of the financial terms of the Merger. The opinion addressed only the fairness, from a financial point of view, of the merger consideration in the Merger to the holders of NB&T Financial common shares. It did not address the underlying business decision of NB&T Financial to engage in the Merger or enter into the Merger Agreement or constitute a recommendation to the NB&T Financial board in connection with the Merger, and it does not constitute a recommendation to any holder of NB&T Financial common shares or any shareholder of any other entity as to how to vote in connection with the Merger or any other matter, nor does it constitute a recommendation on whether or not any such shareholder should enter into a voting, shareholders’ or affiliates’ agreement with respect to the Merger.

KBW’s opinion was reviewed and approved by KBW’s Fairness Opinion Committee in conformity with its policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

In connection with the opinion, KBW reviewed, analyzed and relied upon material bearing upon the financial and operating conditions of NB&T Financial and Peoples and the Merger, including, among other things:

KBW’s consideration of financial information and other factors that it deemed appropriate under the circumstances or relevant to its analyses included, among others, the following:

KBW also performed such other studies and analyses as it considered appropriate and took into account its assessment of general economic, market and financial conditions and its experience in other transactions, as well as its experience in securities valuation and knowledge of the banking industry generally. KBW also held discussions with senior management of NB&T Financial and Peoples regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters that KBW deemed relevant to its inquiry. In addition, KBW considered the results of the efforts undertaken by NB&T Financial, with KBW’s assistance, to solicit indications of interest from third parties regarding a potential transaction with NB&T Financial.

In conducting its review and arriving at its opinion, KBW relied upon and assumed the accuracy and completeness of all of the financial and other information provided to it or publicly available and did not independently verify the accuracy or completeness of any such information or assume any responsibility or liability for such verification, accuracy or completeness. KBW relied upon the management of NB&T Financial as to the reasonableness and achievability of the financial and operating forecasts and projections of NB&T Financial (and the assumptions and bases therefor) that were prepared by NB&T Financial management and provided to and discussed with KBW by such management. KBW assumed, with the consent of NB&T Financial, that such forecasts and projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of NB&T Financial management and that such forecasts and projections would be realized in the amounts and in the time periods estimated by such management. KBW further relied, with the consent of NB&T Financial, upon management of Peoples as to the reasonableness and achievability (i) the publicly available consensus “street estimates” of Peoples (including the assumed long term growth rates based thereon), (ii) the projected balance sheet and capital data of Peoples (giving effect to each of the North Akron acquisition and the Ohio Heritage acquisition) that were reviewed by, and discussed with KBW by, such management, and (iii) the estimates regarding certain pro forma financial effects of the Merger on Peoples that were prepared by or reviewed by Peoples management, and/or discussed by Peoples management with KBW and provided to and discussed with KBW by such management (and the assumptions and bases therefor, including but not limited to the cost savings, revenue enhancements and related expenses expected to result from the merger). KBW assumed, with the consent of NB&T Financial, that all such information was consistent with (in the case of Peoples “street estimates”), or was otherwise reasonably prepared on a basis reflecting, the best currently available estimates and judgments of Peoples management and that such forecasts, estimates and projected data reflected in such information would be realized in the amounts and in the time periods estimated. KBW expressed no view or opinion as to the North Akron acquisition or the Ohio Heritage acquisition (or any terms, aspects or implications of either such transaction) and assumed, with the consent of NB&T Financial, that each such acquisition (including the subsidiary merger related to each acquisition) would be consummated as described to KBW by Peoples management in the third and fourth quarters of 2014, respectively. For purposes of KBW’s opinion and at the direction of the NB&T Financial board, KBW assumed the occurrence in all material respects of the issuances of approximately 2,100,000 Peoples common shares in the pending North Akron acquisition and the then pending Ohio Heritage acquisition and approximately 1,800,000 Peoples common shares in the then pending private placement that occurred in August 2014, which issuances are referred to collectively in this section as the Peoples equity issuances.

It is understood that, other than the publicly available consensus “street estimates” of Peoples that KBW was directed to use, the forecasts, projections and estimates of NB&T Financial and Peoples referred to above were not prepared with the expectation of public disclosure, and that such forecasts, projections and estimates, together with the publicly available consensus “street estimates” of Peoples that KBW was directed to use, were based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions, and, accordingly, actual results could vary significantly from those set forth in such forecasts, projections and estimates. KBW assumed, based on discussions with the

respective management teams of NB&T Financial and Peoples, and at the direction of such managements and with the consent of the NB&T Financial board, that all such information provided a reasonable basis upon which KBW could form its opinion and KBW expressed no view as to any such information or the assumptions or bases therefor. KBW relied on all such information without independent verification or analysis and did not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

KBW also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either NB&T Financial or Peoples since the date of the last financial statements of each such entity that were made available to KBW. KBW is not an expert in the independent verification of the adequacy of allowances for loan and lease losses and KBW assumed, without independent verification and with NB&T Financial’s consent, that the aggregate allowances for loan and lease losses for NB&T Financial and Peoples were adequate to cover such losses. In rendering its opinion, KBW did not make or obtain any evaluations or appraisals or physical inspection of the property, assets or liabilities (contingent or otherwise) of NB&T Financial or Peoples, the collateral securing any of such assets or liabilities, or the collectability of any such assets, nor did KBW examine any individual loan or credit files, nor did it evaluate the solvency, financial capability or fair value of NB&T Financial or Peoples under any state or federal laws, including those relating to bankruptcy, insolvency or other matters. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, KBW assumed no responsibility or liability for their accuracy.

KBW assumed that the Merger would be consummated in a manner that complied with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all

other applicable federal and state statutes, rules and regulations. KBW further assumed that NB&T Financial relied upon the advice of its counsel, independent accountants and other advisors (other than KBW) as to all legal, financial reporting, tax, accounting and regulatory matters with respect to NB&T Financial, Peoples, the Merger, any related transactions (including the subsidiary bank merger and the Peoples equity issuances) and the Merger Agreement. KBW did not provide advice with respect to any such matters.

KBW’s opinion addressed only the fairness, from a financial point of view, as of the date of such opinion, of the merger consideration in the Merger to the holders of NB&T Financial common shares. KBW expressed no view or opinion as to any terms or other aspects of the Merger or any related transaction (including the subsidiary bank merger and the Peoples equity issuances), including without limitation, the form or structure of the Merger (including the form of merger consideration or the allocation of the merger consideration among cash and stock) or any related transaction, any consequences of the Merger or any related transaction to NB&T Financial, its shareholders, creditors or otherwise, or any terms, aspects or implications of any employment, consulting, voting, support, shareholder or other agreements, arrangements or understandings contemplated or entered into in connection with the Merger or otherwise. KBW expressed no view or opinion herein as to either the North Akron acquisition or the Ohio Heritage acquisition, including without limitation any direct or indirect consequence or impact of either the consummation of any one or both acquisitions (further to either of their publicly announced terms (including anticipated timing) or otherwise) or, alternatively, the failure to consummate any one or both such acquisitions, on NB&T Financial, Peoples, the holders of NB&T Financial common shares or Peoples common shares, the Merger (including any term or aspect thereof) or any related transaction, or the prices, trading range or volume of NB&T Financial common shares or Peoples common shares. KBW’s opinion was necessarily based upon conditions as they existed and could be evaluated on the date of such opinion and the information made available to KBW through such date. Developments subsequent to the date of KBW’s opinion may have affected, and may affect, the conclusion reached in KBW’s opinion and KBW did not and does not have an obligation to update, revise or reaffirm its opinion. KBW’s opinion did not address, and KBW expressed no view or opinion with respect to:

In performing its analyses, KBW made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of KBW, NB&T Financial and Peoples. Any estimates contained in the analyses performed by KBW are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, the KBW opinion was among several factors taken into consideration by the NB&T Financial board in making its determination to approve the Merger Agreement and the Merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the NB&T Financial board with respect to the fairness of the merger consideration. The type and amount of consideration payable in the Merger were determined through negotiation between NB&T Financial and Peoples and the decision to enter into the Merger Agreement was solely that of the NB&T Financial board.

The following is a summary of the material financial analyses presented by KBW to the NB&T Financial board in connection with its opinion. The summary is not a complete description of the financial analyses underlying the opinion or the presentation made by KBW to the NB&T Financial board, but summarizes the material analyses performed and presented in connection with such opinion. The preparation of a fairness opinion is a complex analytic process involving various determinations as to appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, KBW did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. Accordingly, KBW believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion. The tables alone do not constitute a complete description of the financial analyses. For purposes of its analyses, KBW utilized an implied merger consideration value of $29.65 per NB&T Financial common share, consisting of (i) $7.75 per share in cash and (ii) the implied value of 0.9319 of a Peoples common share to be exchanged for each NB&T Financial common share based on the closing price of Peoples common shares on August 1, 2014 of $23.50.

Selected Companies Analysis. Using publicly available information, KBW compared the financial performance, financial condition and market performance of NB&T Financial to 25 selected publicly traded banks and thrifts located in the Midwest with total assets between $500 million and $800 million and nonperforming assets / assets ratios less than 3.0%. The selected companies included:

To perform this analysis, KBW used last-twelve-months (“LTM”) profitability data and other financial information as of March 31, 2014 (or, in the case of NB&T Financial, Middlefield Banc Corp., CSB Bancorp, Inc. and Southern Michigan Bancorp, Inc., as of June 30, 2014 to the extent publicly available) and market price information as of August 1, 2014. Certain financial data prepared by KBW, and as referenced in the tables presented below, may not correspond to the data presented in NB&T Financial’s historical financial statements, or the data presented under the section “Opinion of Peoples’ Financial Advisor,” as a result of the different periods, assumptions and methods used by KBW to compute the financial data presented.

KBW’s analysis showed the following concerning the financial performance and financial condition of NB&T Financial and the selected companies:

Note: Texas ratio equal to (NPAs / Loans 90 Days Past Due) / (Tangible Common Equity + Loan Loss Reserves) adjusted for covered loans.

KBW’s analysis also showed, among other things, the following concerning the market performance of NB&T Financial and the selected companies (excluding the impact of certain selected company LTM earnings per share (“EPS”) multiples considered to be not meaningful because they were either below 0.0x or greater than 30.0x):

Using publicly available information, KBW then compared the financial performance, financial condition and market performance of Peoples to 26 selected publicly traded banks and thrifts located in the Midwest with total assets between $1.0 billion and $3.0 billion, nonperforming assets / assets ratios less than 3.0%, and operating returns on assets greater than 0.5%. The selected companies included:

To perform this analysis, KBW used LTM profitability data and other financial information as of March 31, 2014 (or, in the case of Peoples, Mercantile Bank Corporation, MainSource Financial Group, Inc., Stock Yards Bancorp, Inc., First Defiance Financial Corp., Bank of Kentucky Financial Corporation, Alerus Financial Corporation, MutualFirst Financial, Inc., First Citizens Banc Corp and LCNB Corp., as of June 30, 2014 to the extent publicly available) and market price information as of August 1, 2014. 2014 and 2015 earnings estimates for Peoples and the selected companies were taken from a nationally recognized earnings estimate consolidator. Certain financial data prepared by KBW, and as referenced in the tables presented below, may not correspond to the data presented in Peoples’ historical financial statements, or the data presented under the section “Opinion of Peoples’ Financial Advisor,” as a result of the different periods, assumptions and methods used by KBW to compute the financial data presented.

KBW’s analysis showed the following concerning the financial performance and financial condition of Peoples and the selected companies:

Note: Texas ratio equal to (NPAs / Loans 90 Days Past Due) / (Tangible Common Equity + Loan Loss Reserves) adjusted for covered loans.

KBW’s analysis also showed, among other things, the following concerning the market performance of Peoples and, to the extent publicly available, the selected companies:

No company used as a comparison in the above selected companies analysis is identical to NB&T Financial or Peoples. Accordingly, an analysis of these results is not mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies involved.

Selected Transactions Analysis. KBW reviewed publicly available information related to 19 selected nationwide bank merger and acquisition transactions announced since January 1, 2012 in which the target had assets between $400 million and $900 million and nonperforming assets / assets ratios less than 2.0%. The selected transactions included:

For each selected transaction, KBW derived the ratio of the transaction consideration value per common share paid for the acquired company to the following to the extent publicly available, in each case based on the acquired company’s then latest publicly available financial statements prior to the announcement of the acquisition:

The resulting transaction ratios for the selected transactions were compared with corresponding transaction ratios for the proposed merger based on the implied merger consideration value of $29.65 per NB&T Financial common share and using historical financial information for NB&T Financial as of June 30, 2014.

The results of the analysis are set forth in the following table (excluding the impact of certain selected transaction LTM EPS multiples considered to be not meaningful because they were either below 0.0x or greater than 70.0x):

KBW then reviewed publicly available information related to 12 selected Midwest bank merger and acquisition transactions announced since January 1, 2012 in which the target had assets between $250 million and $1.5 billion and nonperforming assets / assets ratios less than 3.0%. The selected transactions included:

No company or transaction used as a comparison in the above selected transactions analysis is identical to NB&T Financial or the proposed merger. Accordingly, an analysis of these results is not mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies involved.

Relative Contribution Analysis. KBW analyzed the relative standalone contribution of Peoples (giving effect to each of the pending North Akron acquisition and the then pending Ohio Heritage acquisition but excluding the effect of the private placement that occurred in August 2014 except as otherwise indicated) and NB&T Financial to various pro forma balance sheet and income statement items of the combined entity. This analysis did not include purchase accounting or transaction adjustments. To perform this analysis, KBW used (i) projected balance sheet data for Peoples and NB&T Financial per Peoples and NB&T Financial managements, (ii) 2014 and 2015 net income consensus “street” estimates for Peoples and an assumed long term growth rate based thereon per Peoples management and (iii) financial forecasts and projections relating to the earnings of NB&T

Financial provided to KBW by NB&T Financial management. The results of KBW’s analysis are set forth in the following table, which also compares the results of KBW’s analysis with the implied pro forma ownership percentage of NB&T Financial shareholders in the combined company both before and after giving effect to an illustrative $42.5 million August 2014 private placement based on the actual exchange ratio of the stock consideration in the proposed merger and also a hypothetical exchange ratio assuming 100% stock consideration:

Pro Forma Financial Impact Analysis. KBW performed a pro forma financial impact analysis that combined projected income statement and balance sheet information of Peoples (giving effect to each of the pending North Akron acquisition and the then pending Ohio Heritage acquisition and also before and after giving effect to an illustrative $42.5 million August 2014 private placement) and NB&T Financial. Using closing balance sheet estimates as of December 31, 2014 for Peoples (before and after giving effect to an illustrative $42.5 million August 2014 private placement) and NB&T Financial per their respective managements, the 2015 consensus “street” earnings estimate for Peoples and an assumed long term growth rate based thereon per Peoples management, financial forecasts and projections relating to the earnings of NB&T Financial provided by NB&T Financial management and pro forma assumptions (including purchase accounting assumptions, cost savings and related expenses) provided by or derived from discussions with Peoples management, KBW analyzed the potential financial impact of the Merger on certain projected financial results. This analysis indicated that the merger could be accretive to Peoples’ 2015 and 2016 estimated EPS and dilutive to Peoples’ estimated closing book value per share and closing tangible book value per share as of December 31, 2014. Furthermore, the analysis indicated that, pro forma for the proposed merger, each of Peoples’ tangible common equity to tangible assets ratio, Tier 1 leverage ratio, Tier 1 Risk-Based Capital Ratio and Total Risk-Based Capital Ratio as of December 31, 2014 could be lower. For all of the above analyses, the actual results achieved by Peoples following the Merger will vary from the projected results, and the variations may be material.

Discounted Cash Flow Analysis. KBW performed a discounted cash flow analysis to estimate ranges for the implied equity value of NB&T Financial. In this analysis, KBW used financial forecasts and projections relating to the earnings and assets of NB&T Financial prepared by and provided to KBW by NB&T Financial management, and assumed discount rates ranging from 12.0% to 16.0%. The ranges of values were determined

by adding (1) the present value of the estimated free cash flows that NB&T Financial could generate over the period from fiscal years 2014 to 2019 as a standalone company and (2) the present value of NB&T Financial’s implied terminal value at the end of such period. KBW assumed that NB&T Financial would maintain a tangible common equity to tangible assets ratio of 8.00% and would retain sufficient earnings to maintain that level. KBW derived implied terminal values using two methodologies, one based on 2020 earnings multiples and the other based on 2019 tangible book value multiples. Using implied terminal values for NB&T Financial calculated by applying a range of 10.0x to 14.0x estimated 2020 earnings, this discounted cash flow analysis resulted in a range of implied value per NB&T Financial common share of $17.22 to $24.36. Using implied terminal values for NB&T Financial calculated by applying a range of 1.00x to 1.40x estimated 2019 tangible book value, this discounted cash flow analysis resulted in a range of implied value per NB&T Financial common share of $16.40 to $22.95. The discounted cash flow analysis is a widely used valuation methodology, but the results of such methodology are highly dependent on the assumptions that must be made, including asset and earnings growth rates, terminal values, dividend payout rates, and discount rates. The analysis did not purport to be indicative of the actual values or expected values of NB&T Financial.

Miscellaneous. KBW acted as financial advisor to NB&T Financial in connection with the proposed merger and did not act as an advisor to or agent of any other person. As part of its investment banking business, KBW is continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, KBW has experience in, and knowledge of, the valuation of banking enterprises. Further to existing sales and trading relationships between KBW and each of NB&T Financial and Peoples, KBW has from time to time, in the ordinary course of its business as a broker-dealer, purchased securities from, and sold securities to, NB&T Financial and Peoples. As a market maker in securities, KBW may from time to time have a long or short position in, and buy or sell, debt or equity securities of NB&T Financial and Peoples for its own account and for the accounts of its customers. Any KBW proprietary or employee positions in NB&T Financial and Peoples, as of the date of KBW’s opinion, were disclosed to NB&T Financial.

Pursuant to the KBW engagement agreement, NB&T Financial agreed to pay KBW a cash fee equal to 1.30% of the aggregate merger consideration, $25,000 of which became payable to KBW in connection with its engagement, $150,000 of which became payable to KBW upon the rendering of the opinion and the balance of which is contingent upon the consummation of the Merger. NB&T Financial also agreed to reimburse KBW for reasonable out-of-pocket expenses and disbursements incurred in connection with its retention and to indemnify KBW against certain liabilities relating to or arising out of KBW’s engagement or KBW’s role in connection therewith. In addition to this present engagement, KBW has provided investment banking and financial advisory services to NB&T Financial in the past two years and received compensation for such services. KBW was engaged by NB&T Financial in October 2013 to provide financial advisory services in connection with a proposed acquisition by NB&T Financial that was not consummated. In the past two years, KBW has from time to time provided investment banking and financial advisory services to Peoples for which KBW did not receive compensation. Among such services were advisory services in connection with Peoples’ prior preliminary consideration of the acquisition of NB&T Financial, on which KBW ceased performing work in August 2013. Prior to the past two years, KBW was engaged by Peoples in May 2012 to provide financial advisory services in connection with another proposed acquisition by Peoples that was not consummated and received compensation for such services. KBW may in the future provide investment banking and financial advisory services to NB&T Financial or Peoples and receive compensation for such services.

Peoples believes that the Merger is in the best interests of Peoples and its shareholders. In reaching this determination, the Peoples board of directors consulted with its management, as well as its financial, accounting and legal advisors, and considered the projected pro forma impact of the Merger and a number of other factors, including, without limitation, the following:

The board of directors of Peoples also considered a variety of risks and other potentially negative factors in deliberations concerning the Merger. In particular, the board of directors of Peoples considered:

The above discussion of the information and factors considered by Peoples’ board of directors is not intended to be exhaustive, but includes all material factors considered by the board in arriving at its determination to approve the Merger and to recommend that the Peoples shareholders approve the Merger Agreement. The board of directors of Peoples did not assign any relative or specific weights to the above factors, and individual directors may have given differing weights to different factors.

The board of directors of Peoples unanimously approved the Merger Agreement and the issuance of common shares in connection therewith. The board of directors of Peoples believes that the Merger and the common share issuance are in the best interests of Peoples and its shareholders, and, as a result, the directors unanimously recommend that Peoples shareholders vote “FOR” the adoption and approval of the Merger Agreement and “FOR” the approval of the issuance of common shares.

Peoples retained Raymond James as its financial advisor on June 2, 2014. Pursuant to that engagement, Peoples’ board of directors requested that Raymond James opine as to the fairness, from a financial point of view, to Peoples of the merger consideration to be paid by Peoples pursuant to the Merger Agreement.

At the request of Peoples’ board of directors, representatives of Raymond James rendered its opinion as to the fairness, as of August 4, 2014, from a financial point of view, to Peoples of the merger consideration to be paid by Peoples in the Merger pursuant to the Merger Agreement, based upon and subject to the qualifications, assumptions and other matters considered in connection with the preparation of its opinion.

The full text of the written opinion of Raymond James is attached as Annex D to this joint proxy statement/prospectus. The summary of the opinion of Raymond James set forth in this document is qualified in its entirety by reference to the full text of such written opinion. Holders of Peoples common stock are urged to read this opinion in its entirety.

Raymond James provided its opinion for the information of Peoples’ board of directors (solely in its capacity as such) in connection with, and for purposes of, its consideration of the Merger and its opinion only addressed whether the merger consideration to be paid by Peoples in the Merger pursuant to the Merger Agreement was fair, from a financial point of view, to Peoples. The opinion of Raymond James does not address any other term or aspect of the Merger Agreement or the Merger contemplated thereby. The Raymond James opinion does not constitute a recommendation to the board or to any holder of Peoples common stock as to how the board, such stockholder or any other person should vote or otherwise act with respect to the Merger or any other matter. Raymond James does not express any opinion as to the likely trading range of Peoples’ common stock following the Merger, which may vary depending on numerous factors that generally impact the price of securities or on the financial condition of Peoples at that time.

In connection with its review of the proposed Merger and the preparation of its opinion, Raymond James, among other things:

With Peoples’ consent, Raymond James assumed and relied upon the accuracy and completeness of all information supplied by or on behalf of Peoples, or otherwise reviewed by or discussed with Raymond James, and Raymond James did not undertake any duty or responsibility to, nor did Raymond James, independently verify any of such information. Raymond James did not make or obtain an independent appraisal of the assets or liabilities (contingent or otherwise) of NB&T Financial. Raymond James is not an expert in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for loan losses; accordingly, Raymond James assumed that such allowances for losses are in the aggregate adequate to cover such losses. With respect to the Projections and any other information and data provided to or otherwise reviewed by or discussed with Raymond James, Raymond James, with Peoples’ consent, assumed that the Projections and such other information and data were reasonably prepared in good faith on bases reflecting the best currently available

estimates and judgments of management of Peoples and Raymond James relied upon Peoples to advise Raymond James promptly if any information previously provided became inaccurate or was required to be updated during the period of its review. Raymond James expressed no opinion with respect to the Projections or the assumptions on which they were based. Based upon the terms specified in the Merger Agreement, Raymond James assumed that the Merger will qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code. Raymond James relied upon and assumed, without independent verification, that the final form of the Merger Agreement would be substantially similar to the draft agreement reviewed by Raymond James in all respects material to its analysis, and that the Merger would be consummated in accordance with the terms of the Merger Agreement without waiver of or amendment to any of the conditions thereto. Furthermore, Raymond James assumed, in all respects material to its analysis, that the representations and warranties of each party contained in the Merger Agreement were true and correct and that each party will perform all of the covenants and agreements required to be performed by it under the Merger Agreement without being waived. Raymond James also relied upon and assumed, without independent verification, that (i) the Merger would be consummated in a manner that complies in all respects with all applicable international, federal and state statutes, rules and regulations, and (ii) all governmental, regulatory or other consents and approvals necessary for the consummation of the Merger would be obtained and that no delay, limitations, restrictions or conditions would be imposed or amendments, modifications or waivers made that would have an effect on the Merger, Peoples, or NB&T Financial that would be material to its analysis or opinion.

Raymond James expressed no opinion as to the underlying business decision to effect the Merger, the structure or tax consequences of the Merger, or the availability or advisability of any alternatives to the Merger. The Raymond James opinion is limited to the fairness, from a financial point of view, of the merger consideration to be paid by Peoples. Raymond James expressed no opinion with respect to any other reasons (legal, business, or otherwise) that may support the decision of Peoples’ board of directors to approve or consummate the Merger. Furthermore, no opinion, counsel or interpretation was intended by Raymond James on matters that require legal, accounting or tax advice. Raymond James assumed that such opinions, counsel or interpretations had been or would be obtained from appropriate professional sources. Furthermore, Raymond James relied, with the consent of Peoples, on the fact that Peoples was assisted by legal, accounting and tax advisors, and, with the consent of Peoples, relied upon and assumed the accuracy and completeness of the assessments by Peoples and its advisors, as to all legal, accounting and tax matters with respect to Peoples and the Merger.

In formulating its opinion, Raymond James considered only the merger consideration to be paid by Peoples, and Raymond James did not consider, and its opinion did not address, the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of NB&T Financial, or such class of persons, in connection with the Merger whether relative to the merger consideration or otherwise. Raymond James was not requested to opine as to, and its opinion did not express an opinion as to or otherwise address, among other things: (1) the fairness of the Merger to the holders of any class of securities, creditors or other constituencies of Peoples, or to any other party, except and only to the extent expressly set forth in the last sentence of its opinion or (2) the fairness of the Merger to any one class or group of Peoples’ or any other party’s security holders or other constituents vis-à-vis any other class or group of Peoples’ or such other party’s security holders or other constituents. Raymond James expressed no opinion as to the impact of the Merger on the solvency or viability of Peoples or the ability of Peoples to pay its obligations when they come due.

The following summarizes the material financial analyses provided by Raymond James to Peoples on August 4, 2014, which analyses were considered by Raymond James in rendering its opinion. No company or

transaction used in the analyses described below is identical or directly comparable to Peoples, NB&T Financial or the contemplated Merger.

Selected Companies Analysis. Raymond James analyzed the relative valuation multiples of 19 publicly-traded depository institutions that it deemed relevant, including:

Raymond James calculated various valuation multiples for each company, including (i) market value (including the in-the-money value of stock options) compared to tangible common equity, for the most recent period ended June 30, 2014 and (ii) market value (including the in-the-money value of stock options) compared to earnings, for the most recent twelve month period ended June 30, 2014, referred to as “LTM”. Raymond James reviewed the mean, median, lower (25^th percentile) quartile and upper (75^th percentile) quartile relative valuation multiples of the selected public companies and compared them to corresponding valuation multiples for NB&T Financial as of August 1, 2014 and implied by the merger consideration. The results of the selected public companies analysis are summarized below:

Furthermore, Raymond James applied the mean, median, lower quartile and upper quartile valuation multiples for each of the metrics to NB&T Financial’s actual and projected financial results and determined the

implied equity price per share of NB&T Financial common stock and then compared those implied equity values per share to the trading value of NB&T Financial as of August 1, 2014 and to the merger consideration of $31.00 per share. The results of this are summarized below:

Selected National Precedent Mergers Analysis. Raymond James analyzed publicly available information relating to 16 selected acquisitions of depository institutions announced since January 1, 2013 in which the transaction values were between $65 million and $200 million and in which the sellers had LTM return on average assets (“ROAAs”) between 0.25% and 1.00% and ratio of non-performing assets (“NPAs”) to assets of less than 4.00%. Raymond James prepared a summary of the aggregate price to tangible book value, aggregate price to LTM earnings, and premium to core deposit multiples paid in these transactions. The selected transactions used in the analysis included (buyer / seller):

Raymond James examined valuation multiples of the aggregate transaction value compared to the target companies’ tangible common equity and earnings, in each case for twelve months ended prior to announcement of the transaction, where such information was publicly available. Raymond James also examined the premium of the aggregate transaction value over tangible common equity as a percentage of core deposits. Raymond James reviewed the mean, median, lower quartile and upper quartile relative valuation multiples of the selected transactions and compared them to corresponding valuation multiples for NB&T Financial implied by the merger consideration. Furthermore, Raymond James applied the mean, median, lower quartile and upper quartile relative

valuation multiples to NB&T Financial’s actual results to determine the implied equity price per share and then compared those implied equity values per share to the merger consideration of $31.00 per share. The results of the selected transactions analysis are summarized below:

Selected Regional Precedent Mergers Analysis. Raymond James analyzed publicly available information relating to eight selected acquisitions of depository institutions headquartered in Indiana, Kentucky, Michigan, Ohio, Pennsylvania and West Virginia announced since January 1, 2013 in which the transaction values were between $50 million and $200 million and in which the sellers had LTM ROAAs between 0.00% and 1.25% and ratio of NPAs to assets of less than 4.00%. Raymond James prepared a summary of the aggregate price to tangible book value, aggregate price to LTM earnings, and premium to core deposit multiples paid in these transactions. The selected transactions used in the analysis included (buyer / seller):

Raymond James examined valuation multiples of the aggregate transaction value compared to the target companies’ tangible common equity and earnings, in each case for the 12 months ended prior to announcement of the transaction, where such information was publicly available. Raymond James also examined the premium of the aggregate transaction value over tangible common equity as a percentage of core deposits. Raymond James reviewed the mean, median, lower quartile and upper quartile relative valuation multiples of the selected

transactions and compared them to corresponding valuation multiples for NB&T Financial implied by the merger consideration. Furthermore, Raymond James applied the mean, median, lower quartile and upper quartile relative valuation multiples to NB&T Financial’s actual results to determine the implied equity price per share and then compared those implied equity values per share to the merger consideration of $31.00 per share. The results of the selected transactions analysis are summarized below:

Discounted Cash Flow Analysis. Raymond James analyzed the discounted present value of NB&T Financial’s projected free cash flows for the years ending December 31, 2015 through 2019 as adjusted for the transaction both with and without projected cost savings. The projected cost savings and merger adjustments to the Projections were provided by Peoples for Raymond James’s use. Raymond James estimated cash flows based on projected excess tangible common equity available to dividend to shareholders, defined as the tangible common equity in excess of a minimum 8.0% tangible common equity to tangible assets ratio.

The discounted cash flow analysis was based on the Projections. Consistent with the periods included in the Projections, Raymond James used calendar year 2019 as the final year for the analysis and applied multiples, ranging from 12.0x to 16.0x, to calendar year 2019 adjusted earnings in order to derive a range of terminal values for NB&T Financial in 2019.

The projected free cash flows and terminal values were discounted using rates ranging from 12.5% to 14.5%, which reflected the cost of equity capital estimated for Peoples using the Ibbotson discount rate build-up method which considers the risk-free rate, equity risk premium, and size premium. The resulting range of present equity values was divided by the number of diluted shares outstanding in order to arrive at a range of present values per NB&T Financial share. Raymond James reviewed the range of per share prices derived in the discounted cash flow analysis and compared them to the price per share for NB&T Financial implied by the merger consideration. The results of the discounted cash flow analysis are summarized below:

Additional Considerations. The preparation of a fairness opinion is a complex process and is not susceptible to a partial analysis or summary description. Raymond James believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering the analyses taken as a whole, would create an incomplete view of the process underlying its opinion. In addition, Raymond James considered the results of all such analyses and did not assign relative weights to any of the analyses, but rather made qualitative judgments as to significance and relevance of each analysis and factor, so the ranges of valuations resulting from any particular analysis described above should not be taken to be the view of Raymond James as to the actual value of NB&T Financial.

In performing its analyses, Raymond James made numerous assumptions with respect to industry performance, general business, economic and regulatory conditions and other matters, many of which are beyond the control of Peoples. The analyses performed by Raymond James are not necessarily indicative of actual values, trading values or actual future results which might be achieved, all of which may be significantly more or less favorable than suggested by such analyses. Such analyses were provided to Peoples’ board of directors (solely in its capacity as such) and were prepared solely as part of the analysis of Raymond James of the fairness, from a financial point of view, to Peoples of the merger consideration to be paid by Peoples in connection with the proposed Merger pursuant to the Merger Agreement. The analyses do not purport to be appraisals or to reflect the prices at which companies may actually be sold, and such estimates are inherently subject to uncertainty. The opinion of Raymond James was one of many factors taken into account by Peoples’ board in making its determination to approve the Merger. Neither Raymond James’ opinion nor the analyses described above should be viewed as determinative of Peoples’ board of directors’ or management’s views with respect to Peoples, NB&T Financial or the Merger. Peoples placed no limits on the scope of the analysis performed, or opinion expressed, by Raymond James.

The Raymond James opinion was necessarily based upon market, economic, financial and other circumstances and conditions existing and disclosed to it on August 1, 2014, and any material change in such circumstances and conditions may affect the opinion of Raymond James, but Raymond James does not have any obligation to update, revise or reaffirm that opinion. Raymond James relied upon and assumed, without independent verification, that there had been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of NB&T Financial since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to Raymond James that would be material to its analyses or its opinion, and that there was no information or any facts that would make any of the information reviewed by Raymond James incomplete or misleading in any material respect.

During the two years preceding the date of Raymond James’s written opinion, Raymond James has been engaged by Peoples as sole placement agent in connection with Peoples’ private placement of common equity completed in August of 2014. In connection with this engagement, Raymond James was paid a customary investment banking fee for its services. Raymond James and certain affiliates also have received compensation from Peoples during the past two years for non-investment banking services.

For services rendered in connection with the delivery of its opinion, Peoples paid Raymond James a customary investment banking fee upon delivery of its opinion. Peoples will also pay Raymond James a customary fee for advisory services in connection with the Merger, all of which is contingent upon the closing of the Merger. Peoples also agreed to reimburse Raymond James for its expenses incurred in connection with its services, including the fees and expenses of its counsel, and will indemnify Raymond James against certain liabilities arising out of its engagement.

Raymond James is actively involved in the investment banking business and regularly undertakes the valuation of investment securities in connection with public offerings, private placements, business combinations and similar transactions. In the ordinary course of business, Raymond James may trade in the securities of Peoples and NB&T Financial for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. Raymond James may provide investment banking, financial advisory and other financial services to Peoples and/or NB&T Financial or other participants in the Merger in the future, for which Raymond James may receive compensation.

The Merger must receive approval from both the OCC and the Federal Reserve before the Merger may be consummated. Peoples has received such approval to consummate the Merger from the OCC and Federal Reserve.

The approval of any regulatory applications merely implies the satisfaction of regulatory criteria for approval, which does not include review of the adequacy or fairness of the merger consideration to NB&T Financial shareholders. Furthermore, regulatory approvals do not constitute or imply any endorsement or recommendation of the Merger or the terms of the Merger Agreement.

As described below, some of NB&T Financial’s directors and executive officers have interests in the Merger that are different from, or in addition to, the interests of NB&T Financial shareholders generally. The NB&T Financial board of directors was aware of these interests and considered them in approving the Merger Agreement.

All of the executive officers of NB&T Financial will receive cash payments for unexercised vested and unvested stock options and continued indemnification and directors’ and officers’ liability insurance coverage. Those executive officers whose employment terminates in connection with or within one year after the Merger will also receive lump sum severance payments and health, life and disability insurance benefits pursuant to employment or severance agreements. Mr. Limbert will also receive a payment of $200,000 for a noncompete provision of his employment agreement. The following table summarizes the estimated value of such payments and benefits that are expected to be paid to each executive officer of NB&T Financial, subject to certain assumptions set forth below the table or explained in more detail in this section of the joint proxy statement/prospectus:

Under the terms of the Merger Agreement, Peoples shall pay to each employee, including officers, of NB&T Financial or NBTC who (i) is not subject to an existing contract providing for severance and/or a change in control payment, (ii) is an employee of NB&T Financial or NBTC immediately before the effective time of the Merger, (iii) has been an employee of NB&T Financial or NBTC for at least six months prior to the effective time of the Merger, and (iv) is not offered continued employment by Peoples or any of its subsidiaries after the effective time of the Merger, or is offered employment outside of 25 miles of such employee’s current normal place of employment, or at a salary less than his or her current salary, a severance amount equal to two week’s base pay multiplied by the number of whole years of service of such employee with NB&T Financial or NBTC, less applicable local, state and federal tax withholding; provided, however, that the minimum severance payment shall equal four weeks of base pay, and the maximum severance payment shall not exceed 26 weeks of base pay. Further, for any employee of NB&T Financial or NBTC participating in NB&T Financial’s or NBTC’s group health program at the effective time of the Merger who is entitled to a severance payment, the employee will be able to purchase health insurance coverage for the employee at the employee premium rate for the first 12 months and the full premium rate for the remaining COBRA period. Each of the current executive officers has an employment or severance agreement and therefore is not expected to receive any severance payments under this provision.

Subject to compliance with applicable state and federal laws, Peoples will indemnify each person who served as a director or officer of NB&T Financial before the effective time of the Merger to the fullest extent provided by NB&T Financial’s governing documents, from and against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement in connection with any threatened, pending or completed action, suit or proceeding by reason of the fact that the person was an officer or director of NB&T Financial. In addition, the Merger Agreement provides that, prior to the Merger, NB&T Financial will purchase a directors’ and officers’ and company liability insurance policy to be effective for up to six years following the effective date of the Merger, on terms no less advantageous than those contained in NB&T Financial’s existing policy.

At or promptly following the effective time of the Merger, Peoples shall take action necessary to elect two members of NB&T Financial’s board of directors, each of whom shall be selected by Peoples, to Peoples’ board of directors (the “Appointees”). It is not yet known which members of NB&T Financial’s board of directors will be selected to serve on Peoples’ board of directors. However, it is estimated that each Appointee will receive annual compensation of $32,750 for their service. This estimated amount is based on the following assumptions: (i) the Appointee serves on the boards of both Peoples and Peoples Bank (currently, all directors of Peoples are also directors of Peoples Bank); (ii) the Appointee attends each of the scheduled monthly meetings of Peoples’ and Peoples Bank’s boards; (iii) the Appointee does not serve on either board’s committees; and (iv) no other discretionary equity-based awards are awarded. The Appointees will be considered and nominated by Peoples’ Governance and Nominating Committee and approved by the full board.

NBTC has entered into employment and/or severance agreements with certain executive officers. Pursuant to those agreements, upon a change in control caused by the Merger, the individuals will be entitled to a lump sum payment if their employment by Peoples Bank terminates within one year following the Merger, due to termination by Peoples Bank or termination by the employee after certain changes in the compensation or employment circumstances of the employee.

Mr. Limbert has an employment agreement with NB&T Financial and NBTC. Under that agreement, if Mr. Limbert’s employment is terminated following the Merger, or if Mr. Limbert voluntarily terminates his employment within one year following the Merger due to certain changes in the conditions of Mr. Limbert’s employment that are expected to occur, Mr. Limbert will be entitled to receive approximately three times his annual salary at the effective time of the Merger and the highest bonus paid to Mr. Limbert during the five years preceding his termination, subject to adjustment to ensure that such payments do not constitute an “excess parachute payment” under Section 280G of the Internal Revenue Code of 1986, as amended, and continuation of health, life and disability coverage under NB&T Financial’s and NBTC’s plans, or Peoples’ and Peoples Bank’s plans, at the expense of NB&T Financial and NBTC, or Peoples and Peoples Bank, for the period allowed under COBRA or until the earlier date that Mr. Limbert is eligible to participate in a similar plans of another employer. In addition, Mr. Limbert will be entitled to receive a lump sum payment of $200,000 in exchange for an agreement not to compete and not to solicit employees or customers for up to two years following termination.

NBTC has also entered into severance agreements with each of several officers. Pursuant to each of those agreements, if the officer is terminated within six months before or within one year after the effective date of the Merger, the officer will be entitled to a payment equal to two times (a) the higher of the officer’s base salary at the time of the Merger or the officer’s base salary at the time of termination of employment, plus (b) the highest bonus paid to the officer during the five years preceding his termination. In addition, the officer and his dependents will be entitled to coverage under the health, life and disability plans of NBTC or Peoples Bank at the expense of NBTC or Peoples Bank until the earliest of the expiration of the term of the agreement, the date the officer is included in another employer’s benefit plans as a full-time employee, or 18 months after the officer’s employment is terminated. The officer may also voluntarily terminate his employment within one year following the Merger upon a material decrease in base compensation or a material change in geographic location at which he is required to perform services and be entitled to the same compensation and benefits as if he were involuntarily terminated.

The change in control payments under the aforementioned agreements would be paid by Peoples or Peoples Bank at or following the effective date of the Merger. The anticipated payment and benefit values under the agreements, assuming a March 6, 2015, Merger effective date, are set forth below.

Stock Options. Immediately prior to the effective time of the Merger, all rights with respect to NB&T Financial’s common shares pursuant to NB&T Financial’s stock option plans will be cancelled in exchange for a cash payment equal to $31.00 less the exercise price per share of each NB&T Financial stock option. All unvested NB&T Financial stock options will be accelerated immediately prior to cancellation in exchange for the cash payment. The following table sets forth the number of shares subject to vested and unvested options held by each person who has been either a director or an executive officer of NB&T Financial since January 1, 2013, and the total payment to be received by each such person upon the closing of the Merger, assuming that none of such options is exercised prior to the closing.

Incentive Plan. NBTC has established an incentive compensation plan for certain employees of NBTC pursuant to which awards are based on NBTC’s achievement of an increase in NBTC’s pre-tax, pre-bonus earnings. All regular full-time and part-time employees are eligible to participate except those who participate in a separate plan where additional compensation is awarded based on loan originations or sales of non-traditional bank products. Messrs. Limbert, Argabright and Fortin are eligible to participate in the incentive plan. Pursuant to the incentive plan, the board of directors establishes a percentage of such earnings improvement that will be directed to a bonus pool for employees participating in the plan. The board of directors may also establish a second tier sharing percentage for pre-tax, pre-bonus earnings improvements that exceed the base expectation. The level of participation by each eligible employee is determined by that employee’s compensation as a percentage of NBTC’s total compensation. The Compensation Committee of NB&T Financial may exclude from determining the level of achievement of NBTC’s performance objectives any extraordinary or significant items. Awards will be paid in cash as soon as practical after the plan year end and after NBTC’s earnings have been reviewed by its auditors.

For 2014, the board of directors of NBTC established a 15% allocation to the bonus pool for NBTC pre-tax, pre-bonus earnings improvement up to $455,000 in 2014 over 2013, and a 25% allocation to the bonus pool for any improvement in earnings in excess of the $455,000 threshold for 2014. At their January 20, 2015 meeting, the board of directors approved a bonus pool of $570,000 for 2014. This bonus pool was allocated to eligible employees, including executive officers, at the rate of 7.4% of eligible wages. The incentive plan provides that upon a change in control, as defined in the plan, all awards will be paid on a pro-rata basis to eligible employees who are employed as of the date of the change in control. The Merger would constitute such a change in control. It is not expected, however, that any pro rata payment will be made upon the consummation of the Merger, as the Merger is not expected to occur until 2015.

The discussion and table below reflect the estimated amount of compensation and benefits that each of the named executive officers of NB&T Financial are entitled to receive where the compensation or benefits are based on or otherwise relate to the Merger. This compensation is referred to as “golden parachute compensation” by the applicable SEC disclosure rules and is the subject of the NB&T Financial advisory (non-binding) proposal on specified compensation, as described in “PROPOSALS SUBMITTED TO NB&T FINANCIAL SHAREHOLDERS—NB&T Financial Advisory (Non-binding) Proposal on Specified Compensation” on page 38.

The amounts in the table below assume the named executive officer resigns for good reason or that his or her employment is terminated without cause on March 6, 2015, that the Merger is completed on March 6, 2015 (the earliest date we believe the closing would occur), and that the Merger constitutes a “change in control” for purposes of the applicable plan or agreement. Amounts do not include compensation benefits available to all of NB&T Financial’s general employees on a non-discriminatory basis. All of the employment arrangements described above comply with or are excepted from Section 409A of the Internal Revenue Code. The amounts reported below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including assumptions described in this document, and do not reflect certain compensation actions that may occur before the completion of the Merger.

As a result of the foregoing assumptions, the actual amounts, if any, to be received by a named executive officer may materially differ from the amounts set forth below.

This section describes the intended, material U.S. federal income tax consequences of the Merger to Peoples, NB&T Financial, and U.S. holders of NB&T Financial common shares who exchange their shares for a combination of Peoples common shares and cash pursuant to the Merger. Peoples and NB&T Financial intend for the Merger to be treated as a reorganization within the meaning of Section 368(a)(1)(A) of the Internal Revenue Code, and Peoples and NB&T Financial intend that each will be a “party to the reorganization” within the meaning of Section 368(b) of the Internal Revenue Code. The closing of the Merger is conditioned upon the receipt by NB&T Financial of an opinion of Vorys, Sater, Seymour and Pease LLP, tax counsel to NB&T Financial, dated as of the effective date of the Merger, substantially to the effect that, on the basis of facts, representations and assumptions set forth in that opinion (including factual representations contained in certificates of officers of Peoples and NB&T Financial), the Merger constitutes a reorganization under Section 368(a) of the Internal Revenue Code. This section summarizes the matters addressed in the tax opinion of Vorys, Sater, Seymour and Pease LLP filed as an exhibit to the registration statement of which this joint proxy statement/prospectus is a part.

Peoples and NB&T Financial have not requested and do not intend to request any ruling from the IRS as to the U.S. federal income tax consequences of the Merger, and the tax opinion to be delivered in connection with the Merger is not binding on the IRS. Consequently, there is no assurance of the accuracy of the anticipated U.S. federal income tax consequences to Peoples, NB&T Financial, and the shareholders of NB&T Financial described in this joint proxy statement/prospectus.

The following discussion is based on the Internal Revenue Code, existing and proposed Treasury Department regulations promulgated thereunder and published rulings and decisions, all as currently in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. Any such change could affect the continuing validity of this discussion.

For purposes of this discussion, a “U.S. holder” is a beneficial owner of NB&T Financial common shares who, for U.S. federal income tax purposes, is:

If a partnership (including for this purpose any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds NB&T Financial common shares, the tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. If you are a partnership, or a partner in such partnership, holding NB&T Financial common shares, you should consult your tax advisor.

This discussion addresses only those NB&T Financial shareholders that hold their NB&T Financial common shares as a capital asset within the meaning of Section 1221 of the Internal Revenue Code (generally, property held for investment), and does not address all of the U.S. federal income tax consequences that may be relevant to particular NB&T Financial shareholders in light of their individual circumstances or to NB&T Financial shareholders that are subject to special rules, such as:

In addition, the discussion does not address any alternative minimum tax, U.S. federal estate or gift tax or any state, local or foreign tax consequences of the Merger. All holders of NB&T Financial common shares should consult their tax advisors as to the specific tax consequences of the Merger to them, including the applicability and effect of the alternative minimum tax and any state, local, foreign and other tax laws.

The Merger is intended to be a reorganization within the meaning of Section 368(a)(1)(A) of the Internal Revenue Code, and Peoples and NB&T Financial are each intended to be a “party to the reorganization” within the meaning of Section 368(b) of the Internal Revenue Code. If the intended reorganization treatment is respected by the Internal Revenue Service and the courts, then the material federal income tax consequences described below are anticipated.

No Gain or Loss. No gain or loss will be recognized by Peoples or NB&T Financial as a result of the Merger.

Tax Basis. The tax basis of the assets of NB&T Financial in the hands of Peoples will be the same as the tax basis of such assets in the hands of NB&T Financial immediately prior to the Merger.

Holding Period. The holding period of the assets of NB&T Financial to be received by Peoples will include the period during which such assets were held by NB&T Financial.

Federal Income Tax Consequences to U.S. Holders of NB&T Financial Common Shares who Receive a Combination of Cash and Peoples Common Shares

A U.S. holder of NB&T Financial common shares will recognize gain (but not loss) with respect to the Peoples common shares such holder receives pursuant to the Merger, in an amount equal to the lesser of (i) the amount by which the sum of the fair market value of the Peoples common shares and the amount of cash received by such holder (other than cash received in lieu of a fractional Peoples common share), exceeds such holder’s basis in its NB&T Financial common shares, and (ii) the amount of cash received by such holder (other than any cash received in lieu of a fractional Peoples common share, as discussed below under “—Cash In Lieu of a Fractional Shares”). Any recognized gain could be taxed as a capital gain or a dividend, as described below. The tax basis of the Peoples common shares received by such U.S. holder (including a fractional Peoples common share, if any, deemed issued and redeemed by Peoples) will be the same as the basis of the NB&T Financial common shares surrendered in exchange for the Peoples common shares, reduced by the amount of cash received by such holder in the Merger (other than any cash received in lieu of a fractional Peoples common share), and increased by any gain recognized by such U.S. holder in the Merger (including any portion of the gain that is treated as a dividend (as described below), but excluding any gain or loss resulting from the deemed issuance and redemption of a fractional Peoples common share). The holding period for Peoples common shares received by such U.S. holder will include such U.S. holder’s holding period for NB&T Financial’s common shares surrendered in exchange for the Peoples common shares (including a fractional Peoples common share, if any, deemed to be issued and redeemed by Peoples).

If a U.S. holder of NB&T Financial common shares acquired different blocks of NB&T Financial common shares at different times or at different prices, any gain or loss will be determined separately with respect to each block of NB&T Financial common shares. In computing the amount of gain recognized, if any, a U.S. holder of NB&T Financial common shares may not offset a loss realized on one block of shares against the gain realized on another block of shares. U.S. holders of NB&T Financial common shares should consult their tax advisors regarding the manner in which Peoples common shares and cash received in the Merger should be allocated among different blocks of NB&T Financial common shares and regarding their bases and holding periods in the particular shares of Peoples common shares received in the Merger.

Subject to possible dividend treatment (as discussed in more detail under “Possible Dividend Treatment”, below), gain or loss that U.S. holders of NB&T Financial common shares recognize in connection with the Merger generally will constitute capital gain or loss and will constitute long-term capital gain or loss if such holders have held their NB&T Financial common shares for more than one year at the effective time of the Merger. Long-term capital gain of certain non-corporate holders of NB&T Financial common shares, including individuals, is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations.

A U.S. holder of NB&T Financial common shares that receives cash in lieu of a fractional Peoples common share generally will be treated as having received such fractional share and then having received such cash in redemption of such fractional share. Gain or loss generally will be recognized based on the difference between the amount of cash received in lieu of the fractional share and the portion of the U.S. holder’s aggregate adjusted basis in the NB&T Financial common shares surrendered which is allocable to the fractional share. Subject to possible dividend treatment (as discussed in more detail under “Possible Dividend Treatment”, below), such gain or loss generally will be long-term capital gain or loss if the U.S. holder’s holding period for its NB&T Financial shares exceeds one year at the effective time of the Merger.

A U.S. holder of NB&T Financial common shares who properly exercises its dissenters’ rights and receives solely cash in exchange for all of its NB&T Financial common shares (and is not treated as constructively owning Peoples’ common shares after the Merger under the circumstances referred to below under “Possible Dividend Treatment”) will recognize a gain or loss for federal income tax purposes equal to the difference between the cash received and such U.S. holder’s tax basis in NB&T Financial’s common shares surrendered in exchange for the cash. Such gain or loss will be a capital gain or loss, provided that such shares were held as capital assets of the U.S. holder at the effective time of the Merger. Such gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period is more than one year. The Internal Revenue Code contains limitations on the extent to which a taxpayer may deduct capital losses from ordinary income.

In some cases, if a U.S. holder of NB&T Financial common shares actually or constructively owns Peoples common shares other than the Peoples common shares received pursuant to the Merger, the gain recognized by such holder could be treated as having the effect of the distribution of a dividend under the tests set forth in Section 302 of the Internal Revenue Code, in which case such gain would be treated as dividend income. Because the possibility of dividend treatment depends primarily upon each holder’s particular circumstances, including the application of certain constructive ownership rules, U.S. holders of NB&T Financial common shares should consult their tax advisors regarding the application of the foregoing rules to their particular circumstances.

Under certain circumstances, cash payments made to a U.S. holder of NB&T Financial common shares pursuant to the Merger may be subject to backup withholding at a rate of 28% of the cash payable to the holder, unless the holder furnishes its taxpayer identification number in the manner prescribed in applicable Treasury Department regulations, and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a holder under the backup withholding rules are not an additional tax and will be allowed as a refund or credit against the holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the Internal Revenue Service.

A U.S. holder of NB&T Financial common shares owning at least 5% (by vote or value) of the outstanding shares of NB&T Financial common shares or having a basis of $1,000,000 or more in its NB&T Financial common shares, immediately before the Merger, is required to file a statement with such holder’s U.S. federal income tax return setting forth such holder’s tax basis in and the fair market value of shares of the NB&T Financial common shares exchanged by such holder pursuant to the Merger. In addition, all U.S. holders of NB&T Financial common shares will be required to retain records pertaining to the Merger.

The preceding discussion of material U.S. federal income tax consequences of the Merger is included in this joint proxy statement/prospectus for general information only, and is intended only as a summary of material U.S. federal income tax consequences of the Merger. It is not a complete analysis or discussion of all potential tax effects that may be important to you.

Each NB&T Financial shareholder should consult with his, her or its own tax advisor regarding the specific tax consequences to the shareholder of the Merger, including the application and effect of state, local and foreign income and other tax laws.

The Merger will be accounted for under the acquisition method of accounting in accordance with generally accepted accounting principles in the United States. Under the acquisition method of accounting, the assets and liabilities of NB&T Financial will be recorded and assumed at estimated fair values at the time the Merger is

consummated. The excess of the estimated fair value of Peoples’ common shares issued and the cash proceeds paid over the net fair values of the assets acquired, including identifiable intangible assets, and liabilities assumed will be recorded as goodwill and will not be deductive for income tax purposes. Goodwill will be subject to an annual test for impairment and the amount impaired, if any, will be charged as an expense at the time of impairment.

Peoples has registered its common shares to be issued in the Merger with the SEC under the Securities Act of 1933, as amended (the “Securities Act”). No restrictions on the sale or other transfer of Peoples’ common shares issued in the Merger will be imposed solely as a result of the Merger, except for restrictions on the transfer of Peoples’ common shares issued to any NB&T Financial shareholder who may become an “affiliate” of Peoples for purposes of Rule 144 under the Securities Act. The term “affiliate” is defined in Rule 144 under the Securities Act and generally includes executive officers, directors and shareholders beneficially owning 10% or more of the outstanding Peoples’ common shares.

The Merger Agreement provides that employees of NB&T Financial or NBTC who become employees of Peoples as a result of the Merger will, as determined by Peoples, participate in either NB&T Financial’s employee benefit plans or, as soon as administratively practicable, in the employee benefit plans sponsored by Peoples for Peoples’ employees. Employees of NB&T Financial or NBTC will receive credit for their years of service with NB&T Financial or NBTC, as applicable, for participation and vesting purposes under the applicable Peoples employee benefit plans, including credit for years of service and for seniority under vacation and sick pay plans and programs. The employee benefit plans offered to NB&T Financial or NBTC employees who become employees of Peoples will be substantially similar to those offered to similarly situated employees of Peoples. In addition, Peoples will waive all restrictions and limitations on pre-existing conditions shall be waived to the extent the group health plan and insurance policy of Peoples or Peoples Bank permit (or may be amended to permit).

Subject to any applicable regulatory restrictions, Peoples has agreed to pay to each employee of NB&T Financial or NBTC who (i) is not subject to an existing contract providing for severance and/or a change in control payment, (ii) is an employee of NB&T Financial or NBTC immediately before the effective time of the Merger, (iii) has been an employee of NB&T Financial or NBTC for at least six months prior to the Effective Time, and (iv) is not offered continued employment by Peoples or any of its subsidiaries after the effective time of the Merger, or is offered employment outside of 25 miles of such employee’s current normal place of employment, or at a salary less than his or her current salary, a severance amount. The severance amount is equal to two weeks’ base pay multiplied by the number of whole years of service of such employee with NB&T Financial or NBTC, less applicable local, state and federal tax withholding; provided, however, that the minimum severance payment will equal four weeks of base pay, and the maximum severance payment will not exceed 26 weeks of base pay. Further, for any employee of NB&T Financial or NBTC participating in NB&T Financial’s or NBTC’s group health program at the effective time of the Merger who is entitled to a severance payment, the employee will be able to purchase health insurance coverage for the employee at the employee premium rate for the first 12 months and the full premium rate for the remaining COBRA period.

NB&T Financial is required to terminate the NB&T Financial ESOP and the NBTC 401(k) Plan effective immediately prior to the effective time of the Merger. In addition, as soon as feasible after the closing of the Merger, Peoples will take commercially reasonable steps to allow NB&T Financial or NBTC employees who continue as employees of Peoples or Peoples Bank to participate in the Peoples 401(k) Plan and to: (i) permit the in-kind rollover of Peoples common shares received as merger consideration into Peoples’ 401(k) Plan, and (ii) accept roll-overs of benefits and participant loan notes from the NBTC 401(k) Plan to the Peoples 401(k) plan.

The following is a description of the material terms of the Merger Agreement. A complete copy of the Merger Agreement is attached as Annex A to this joint proxy statement/prospectus and is incorporated into this joint proxy statement/prospectus by reference. We encourage you to read the Merger Agreement carefully, as it is the legal document that governs the Merger.

The Merger Agreement contains representations and warranties of NB&T Financial and Peoples. The assertions embodied in those representations and warranties are qualified by information contained in confidential disclosure schedules that the parties delivered in connection with the execution of the Merger Agreement. In addition, certain representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from the standard of materiality generally applicable to statements made by a corporation to shareholders or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts, or for any other purpose, at the time they were made or otherwise.

Pursuant to the terms and subject to the conditions of the Merger Agreement, NB&T Financial will merge with and into Peoples, with Peoples surviving the Merger and continuing as an Ohio corporation and a registered financial holding company. Thereafter, at a later time specified by Peoples Bank in its certificate of merger filed with the OCC, Peoples will cause NBTC to be merged with and into Peoples Bank, with Peoples Bank surviving the Merger and continuing as a national banking association.

Peoples and NB&T Financial will cause the effective date of the Merger to occur as soon as practicable after the last of the conditions set forth in the Merger Agreement have been satisfied or waived. Unless Peoples and NB&T Financial otherwise agree in writing, the effective date of the Merger will not be later than March 31, 2015. The Merger will become effective upon the later to occur of (a) the filing of a certificate of merger with the Ohio Secretary of State, or (b) at a later time that Peoples and NB&T Financial agree to in writing and specify in the certificate of merger.

Peoples and NB&T Financial currently anticipate closing the Merger and filing the certificate of merger with the Ohio Secretary of State in the first quarter of 2015.

Peoples will not issue any fractional common shares in connection with the Merger. Instead, each holder of NB&T Financial common shares who would otherwise be entitled to receive a fraction of a Peoples common share (after taking into account all shares of NB&T Financial common shares owned by such holder at the effective time of the Merger) will receive cash, without interest, in an amount equal to the Peoples fractional common share to which such holder would otherwise be entitled multiplied by the average closing sale price of a Peoples common share on the NASDAQ for the 10 consecutive trading days immediately preceding the effective date of the Merger.

At the effective time of the Merger, NB&T Financial’s common shares will no longer be outstanding and will automatically be cancelled and cease to exist, and holders of NB&T Financial common shares will cease to be, and will have no rights as, shareholders of NB&T Financial, other than (a) to receive any dividend or other distribution with respect to such holder’s NB&T Financial common shares, (b) to receive the merger consideration pursuant to the terms and conditions of the Merger Agreement, or (c) to dissenters’ rights under Section 1701.85 of the OGCL in the case of NB&T Financial common shares as to which a holder has properly exercised dissenters’ rights.

Peoples will engage Wells Fargo Shareowner Services (the “Exchange Agent”) to act as its exchange agent to handle the exchange of NB&T Financial common shares for the merger consideration. Within five business days after the effective time, the Exchange Agent will send to each NB&T Financial shareholder a letter of transmittal for use in the exchange with instructions explaining how to surrender NB&T Financial common share certificates to the Exchange Agent. NB&T Financial shareholders that surrender their certificates to the Exchange Agent, together with a properly completed letter of transmittal, will receive the merger consideration. NB&T Financial shareholders that do not exchange their NB&T Financial common shares will not be entitled to receive the merger consideration or any dividends or other distributions by Peoples until their certificates are surrendered. After surrender of the certificates representing NB&T Financial shares, any unpaid dividends or distributions with respect to Peoples common shares represented by the certificates will be paid without interest.

If any NB&T Financial stock certificate has been lost, wrongfully taken, or destroyed, the transmittal materials received from the Exchange Agent will explain the steps that the NB&T Financial shareholder must take.

Immediately prior to the effective time of the Merger, all rights with respect to NB&T Financial’s common shares pursuant to NB&T Financial’s stock option plans shall be cancelled in exchange for a cash payment equal to $31.00 less the exercise price per share of such NB&T Financial stock option. All unvested NB&T Financial stock options will be accelerated immediately prior to cancellation in exchange for the cash payment.

Indemnification and Directors’ and Officers’ and Company Liability Insurance

After the effective time of the Merger and subject to compliance with applicable state and federal laws, Peoples will indemnify each person who served as a director or officer of NB&T Financial before the effective time of the Merger to the fullest extent provided by NB&T Financial’s governing documents, from and against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement in connection with any threatened, pending or completed action, suit or proceeding by reason of the fact that the person was an officer or director of NB&T Financial. In addition, the Merger Agreement provides that, prior to the Merger, NB&T Financial will procure, at the expense of Peoples, a policy of directors’ and officers’ and company liability insurance to be effective for a period of six years following the Merger, on terms no less advantageous than those contained in NB&T Financial’s existing policy.

Peoples common shares currently are listed on the NASDAQ Global Select Market^® under the symbol “PEBO.” The shares to be issued to NB&T Financial’s shareholders as Merger consideration also will be eligible for trading on the NASDAQ. Peoples will use its reasonable best efforts to: (i) list, prior to the effective time if such listing is required to be made prior to the effective time under NASDAQ rules, the Peoples common shares to be issued pursuant to the Merger, or (ii) make such post-closing filings with NASDAQ as may be required by the applicable NASDAQ rules.

Conditions of Peoples and NB&T Financial. The respective obligations of Peoples and NB&T Financial to complete the Merger are subject to the fulfillment or written waiver of each of the following conditions:

Peoples has made customary representations and warranties in the Merger Agreement relating to:

From the date of the Merger Agreement until the effective time of the Merger, except as expressly contemplated or permitted by the Merger Agreement or required by any applicable law, regulatory order or regulation, without the prior written consent of Peoples, NB&T Financial and NBTC must conduct the business of NB&T Financial and NBTC in the ordinary course and use commercially reasonable efforts to preserve intact their respective business organizations and assets and maintain their respective rights, franchises and existing relations with customers, suppliers, vendors, employees and business associates, and not (i) voluntarily take any action which, at the time taken, is reasonably likely to have an adverse effect on NB&T Financial or NBTC, or (ii) enter into any new line of business or materially change its lending, investment, underwriting, risk, asset liability management or other banking and operating policies, except as required by applicable law or policies imposed by any governmental authority or by any applicable regulatory order.

During the same period, NB&T Financial has agreed not to, and to cause NBTC not to, take any of the following actions without the prior written consent of Peoples, except as otherwise expressly contemplated or permitted by the Merger Agreement or required by any applicable law, regulatory order or regulation:

Under the terms of the Merger Agreement and as a condition precedent to the consummation of the Merger, NB&T Financial is required to surrender its ownership interest in its wholly-owned subsidiary NB&T Title, LLC prior to the effective time of the Merger to satisfy regulatory compliance issues following the effective date of the Merger.

Peoples and NB&T Financial are each required to bear their own expenses incurred in connection with the Merger Agreement and the transactions contemplated by the Merger Agreement.

Termination by mutual consent. Peoples and NB&T Financial may mutually consent to terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective, if the boards of directors of Peoples and NB&T Financial both approve the termination by vote of a majority of the members of the entire board.

Termination by either Peoples or NB&T Financial. Either Peoples or NB&T Financial acting alone upon written notice to the other party may terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective, if the Peoples or NB&T Financial board of directors approves the termination by vote of a majority of the members of its entire board in the following circumstances:

Termination by Peoples. Peoples may terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective upon written notice to NB&T Financial if the NB&T Financial board of directors:

Termination by NB&T Financial. NB&T Financial may terminate the Merger Agreement and abandon the Merger at any time before the Merger is effective upon written notice to Peoples:

Under the Merger Agreement, the directors of NB&T Financial executed a voting agreement pursuant to which they agreed to vote such shares of NB&T Financial stock owned directly or indirectly by the directors, and to request their spouses to consent to such agreement to the extent of such spouse’s interest in such shares in favor of the Merger.

Pursuant to the Merger Agreement, NB&T Financial may not, and must cause NBTC and its officers, directors, employees and other agents not to, directly or indirectly take any action to (i) solicit, initiate, encourage, facilitate or induce any inquiries, proposals or offers, or engage in negotiations concerning, or provide

any confidential information to, any person other than Peoples with respect to any inquiry, proposal or offer, (ii) take any action intended to facilitate an inquiry or proposal, (iii) approve, endorse or recommend any other transaction or proposal, or (iv) propose or agree to do any of the foregoing, unless (a) NB&T Financial’s board of directors, after consultation with and based upon the advice of legal counsel, determines in good faith that it must enter into negotiations or discussions with another party that has made an unsolicited acquisition proposal in order to fulfill its fiduciary duties to NB&T Financial shareholders under applicable law and (b) before furnishing any information to, or entering into discussions or negotiations with another party, NB&T Financial provides immediate written notice to Peoples of such action, the identity of the bidder and the substance of such unsolicited acquisition proposal.

If (a) Peoples terminates the Merger Agreement due to NB&T Financial’s acceptance of another acquisition proposal, failure to recommend to the shareholders adoption of the Merger Agreement, or NB&T Financial’s breach of the voting agreement or the Merger Agreement’s prohibition on solicitation of other acquisition proposals, or, (b) NB&T Financial terminates the Merger Agreement with the intention of entering into or accepting an alternate, superior proposal, then, in the case of either (a) or (b) above, NB&T Financial shall pay to Peoples $4.368 million.

The Merger Agreement may be amended or modified at any time prior to the effective time of the Merger by an agreement in writing signed by Peoples and NB&T Financial, except that the Merger Agreement may not be amended after either the NB&T Financial or Peoples special meeting if such amendment would violate Ohio law.

Those shareholders of NB&T Financial that do not exercise dissenters’ rights will receive Peoples common shares in the Merger and, therefore, will become shareholders of Peoples. Their rights as shareholders of Peoples will be governed by the Ohio Revised Code and by Peoples’ Amended Articles of Incorporation and Regulations, while NB&T Financial shareholders are currently governed by the Ohio Revised Code and by NB&T Financial’s Third Amended and Restated Articles of Incorporation and Amended and Restated Code of Regulations. Although the rights of the holders of Peoples’ common shares and those of the holders of shares of NB&T Financial’s common shares are similar in many respects, there are some differences. These differences relate to differences between provisions of the Amended Articles of Incorporation of Peoples and the Third Amended and Restated Articles of Incorporation of NB&T Financial, and differences between provisions of the Regulations of Peoples and the Regulations of NB&T Financial.

The following chart compares certain rights of the holders of shares of NB&T Financial’s common shares to the rights of holders of Peoples’ common shares in areas where those rights are materially different. This summary, however, does not purport to be a complete description of such differences and is qualified in its entirety by reference to the relevant provisions of Ohio law and the respective corporate governance instruments of NB&T Financial and Peoples.

(iii) Cause the Merger to fail to qualify as a “reorganization” within the meaning of Code Section 368(a)(1)(A) of the Code; or

NB&T Financial, if requested by Peoples, shall enter into one or more amendments to this Agreement in order to effect any such change.

2.02 The Subsidiary Merger. At the time specified by Peoples Bank in its certificate of merger filed with the OCC (which shall not be earlier than the Effective Time), NBTC shall merge with and into Peoples Bank (the “Subsidiary Merger”) pursuant to an agreement to merge (the “Agreement to Merge”) to be executed by NBTC and Peoples Bank and filed with the OCC. Upon the consummation of the Subsidiary Merger, the separate corporate existence of NBTC shall cease and Peoples Bank shall survive the Subsidiary Merger and continue to exist as a national bank (Peoples Bank, as the resulting bank in the Subsidiary Merger, is sometimes referred to herein as the “Resulting Bank”) and the separate corporate existence of NBTC shall cease.

2.03 Effectiveness of Parent Merger. Subject to the satisfaction or waiver of the conditions set forth in Article VII of this Agreement, the Parent Merger shall become effective upon the later to occur of the following: (a) the filing of the certificate of merger with the OSS; or (b) such later date and time as may be set forth in such certificate of merger. The Parent Merger shall have the effects prescribed in the OGCL.

2.04 Effective Date and Effective Time. Subject to the satisfaction or waiver of the conditions set forth in Article VII of this Agreement, Peoples and NB&T Financial shall cause the effective date of the Parent Merger (the “Effective Date”) to occur as soon as practicable after the last of the conditions set forth in Article VII shall have been satisfied or waived in accordance with the terms of this Agreement; provided, however, that the Effective Date shall not fall after the date specified in Section 8.01(c) or after the date or dates on which any Regulatory Authority approval or any extension thereof expires. The time on the Effective Date when the Parent Merger shall become effective is referred to herein as the “Effective Time”.

At the Effective Time, by virtue of the Parent Merger and without any action on the part of the holder thereof:

(a) Conversion of NB&T Financial Common Shares. Subject to Sections 3.03, 3.04 and 3.05(b), and except as otherwise provided by paragraph (b) of this Section 3.01, each NB&T Financial Common Share (other than Treasury Shares and Dissenting Shares) issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, as follows, without interest:

(i) a number of Peoples Common Shares equal to the Exchange Ratio (the “Per Share Stock Consideration”); and

(i) If the number of NB&T Financial Common Shares issued and outstanding immediately prior to the Effective Time exceeds the number of NB&T Financial Common Shares issued and outstanding as of the date hereof, except to the extent such increase is due to the exercise of NB&T Financial Options or the issuance of NB&T Financial Common Shares pursuant to the dividend reinvestment feature of the NB&T Financial ESOP, the Merger Consideration will not be adjusted as a result of such excess, though appropriate adjustments will be made to the Per Share Stock Consideration and the Per Share Cash Consideration.

(ii) If Peoples changes (or establishes a record date for changing) the number of shares of Peoples Common Shares issued and outstanding prior to the Effective Time by way of a stock split, stock dividend, recapitalization or similar transaction with respect to the outstanding Peoples Common Shares, and the record date therefor shall be prior to the Effective Time, the Exchange Ratio shall be adjusted so the shareholders of NB&T Financial at the Effective Time shall receive Merger Consideration that produces the same economic effect as contemplated by this Agreement prior to such action.

(c) Treasury Shares. All Treasury Shares shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor.

(d) Dissenting Shares. Notwithstanding anything contained in this Agreement or elsewhere to the contrary, any holder of an outstanding NB&T Financial Common Share that seeks relief as a dissenting shareholder under Section 1701.85 of the OGCL shall thereafter have only such rights (and shall have such obligations) as are provided therein, and the Surviving Corporation shall be required to deliver only such cash payments to which the Dissenting Shares are entitled pursuant to 1701.85 of the OGCL. If any holder of Dissenting Shares shall forfeit such right to payment of the fair value under Section 1701.85 of the OGCL, each holder’s Dissenting Shares shall thereupon be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration, without interest.

3.02 Rights as Shareholders; Share Transfers. At the Effective Time, holders of NB&T Financial Common Shares shall cease to be, and shall have no rights as, shareholders of NB&T Financial, other than (a) to receive any dividend or other distribution with respect to such NB&T Financial Common Shares with a record date occurring prior to the Effective Time, (b) to receive the Per Share Merger Consideration, or (c) to dissenting shareholders’ rights in the case of Dissenting Shares. After the Effective Time, there shall be no transfers on the stock transfer books of NB&T Financial or the Surviving Corporation of any NB&T Financial Common Shares.

(a) Exchange Agent. Wells Fargo Shareowner Services, or any another transfer agent selected by Peoples, will act as the exchange agent (the “Exchange Agent”) for purposes of conducting the exchange and payment procedures as described in this Section 3.03.

(b) Exchange Fund. At or prior to the Effective Time, Peoples shall deposit, or cause to be deposited, with the Exchange Agent cash in an aggregate amount sufficient to make the appropriate payments (i) of the Per Share Cash Consideration, (ii) in lieu of fractional shares pursuant to Section 3.03(d) and (iii) cash payment due to holders of the NB&T Financial Options pursuant to Section 3.04 (such certificates and cash being referred to as the “Exchange Fund”). The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Peoples; provided that no such investment or losses thereon shall affect the amount of Merger Consideration payable to the holders of NB&T Financial Common Shares. Any interest and other income resulting from such investments shall be paid to Peoples. The Exchange Agent shall not be entitled to vote or to exercise any rights of ownership with respect to the Peoples Common Shares held by it in the Exchange Fund, except that it shall receive and hold in trust for the recipients of the Peoples Common Shares until distributed thereto pursuant to the provision of this Agreement all dividends or other distributions paid or distributed with respect to such Peoples Common Shares for the account of the persons entitled thereto. The Exchange Fund shall not be used for any other purpose, except as provided in this Agreement.

(i) Within five business days after the Effective Time, Peoples shall instruct the Exchange Agent to mail to each holder of record of an outstanding certificate or certificates which, as of the Effective Time, represented NB&T Financial Common Shares (other than Treasury Shares and Dissenting Shares) (“Old Certificates”) or uncertificated shares (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the shares of Old Certificates shall pass, only upon proper delivery of the Old Certificates, if applicable, or upon delivery of the letter of transmittal in the case of uncertificated shares, to the Exchange Agent, and which shall be in customary form as directed by Peoples and reasonably acceptable to NB&T Financial, and (ii) instructions for use in effecting the surrender of the Old Certificates, if applicable, or the letter of transmittal in exchange for the Merger Consideration. Upon the proper surrender of the Old Certificates, if applicable, and a properly completed and duly executed letter of transmittal to the Exchange Agent, and such other documents as may reasonably be required by Peoples or the Exchange Agent, the holders of such Old Certificates or uncertificated shares shall be entitled to receive the number of whole shares of Peoples Common Shares that such holder has the right to receive pursuant to Section 3.01(a)(i) and a check in the amount equal to the cash that such holder has the right to receive pursuant to Section 3.01(a)(ii) (including any cash in lieu of fractional shares, if any, that such holder has the right to receive pursuant to Sections 3.01 and 3.03, and any dividends or other distributions to which such holder is entitled pursuant to Section 3.02). Old Certificates so surrendered shall forthwith be canceled. Within ten days following receipt of the properly completed letter of transmittal and any necessary accompanying documentation, the Exchange Agent shall distribute Peoples Common Shares and cash as provided herein. If there is a transfer of ownership of any shares of NB&T Financial Common Shares not registered in the transfer records of NB&T Financial, the Merger Consideration shall be issued to the transferee thereof if the Old Certificates representing such NB&T Financial Common Shares are presented to the Exchange Agent, accompanied by all documents required, in the reasonable judgment of Peoples and the Exchange Agent, to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

(ii) No dividends or other distributions declared or made after the Effective Time with respect to Peoples Common Shares issued pursuant to this Agreement shall be remitted to any person entitled to receive shares of Peoples Common Shares hereunder until such Person surrenders his, her or its Old Certificates, if applicable, and the letter of transmittal in accordance with this Section 3.03. Upon the surrender of such Person’s Old Certificates, if applicable, and the letter of transmittal, such Person shall be entitled to receive any dividends or other distributions, without interest thereon, which subsequent to the Effective Time had become payable but not paid with respect to shares of Peoples Common Shares represented by such Person’s Old Certificates or uncertificated shares.

(d) No Fractional Peoples Common Shares. No certificates representing fractional Peoples Common Shares shall be issued upon the surrender for exchange of the Old Certificates, and such fractional Peoples Common Share interests will not entitle the owner thereof to vote or to any rights of a shareholder of the Surviving Corporation. Each holder of NB&T Financial Common Shares who would otherwise be entitled to receive a fractional Peoples Common Share shall receive from the Exchange Agent an amount of cash equal to the product obtained by multiplying (i) the fractional Peoples Common Share interest to which such holder (after taking into account all NB&T Financial Common Shares held at the Effective Time by such holder) would otherwise be entitled by (ii) the average of the daily closing sales prices of a share of Peoples Common Shares as reported on The NASDAQ Global Select Market^® for the ten consecutive trading days immediately preceding the Effective Date.

(e) Release of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the shareholders of NB&T Financial for six months after the Effective Time shall be paid to Peoples. Any shareholders of NB&T Financial who have not theretofore complied with this Article III shall thereafter look only to Peoples for payment of the Merger Consideration.

(f) No Liability. None of Peoples, NB&T Financial or the Exchange Agent shall be liable to any former holder of NB&T Financial Common Shares for any payment of the Per Share Stock Consideration, the Per Share Cash Consideration, any cash in lieu of a fractional Peoples Common Share interest, or any dividends or distributions with respect to Peoples Common Shares delivered to a public official if required by any applicable abandoned property, escheat or similar law.

(g) Lost Certificates. If any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Old Certificate to be lost, stolen or destroyed in form and substance acceptable to Peoples and, if required by Peoples or the Exchange Agent, the posting by such Person of a bond, in such reasonable amount as Peoples or the Exchange Agent may direct, as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of the shares of NB&T Financial Common Shares represented by such Old Certificate.

(h) Withholding Rights. Peoples or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of NB&T Financial Common Shares such amounts as Peoples or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any other provision of domestic or foreign tax law (whether national, federal, state, provincial, local or otherwise). To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Peoples or the Peoples Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the NB&T Financial Common Shares.

(i) Book Entry. All shares of Peoples Common Shares to be issued in the Merger shall be issued in book entry form, without physical certificates; provided, that Peoples may issue any of such shares in physical form at its sole discretion.

(j) Waiver. The Surviving Corporation may from time to time, in the case of one or more Persons, waive one or more of the rights provided to it in this Article III to withhold certain payments, deliveries and distributions; and no such waiver shall constitute a waiver of its rights thereafter to withhold any such payment, delivery or distribution in the case of any person.

(a) Immediately prior to the Effective Time, all rights with respect to NB&T Financial Common Shares pursuant to NB&T Financial Option Plans (the “NB&T Financial Options”) shall be cancelled in exchange for a cash payment equal to $31.00 less the exercise price per share of such NB&T Financial Option (the “Option Cash-Out Amount”). All unvested NB&T Financial Options will be accelerated immediately prior to cancellation in exchange for the cash payment in accordance with this Section 3.04.

(b) The NB&T Financial Board and its compensation committee shall not make any grants of NB&T Financial Options following the execution of this Agreement, except grants required to be made to the directors of NB&T Financial pursuant to the NB&T Financial 2014 Equity Plan immediately following each annual meeting of shareholders.

(c) The NB&T Financial Board or its compensation committee shall make such adjustments and amendments to or make such determinations with respect to the NB&T Financial Options to effect the foregoing provisions of this Section 3.04.

(a) For federal income tax purposes, the Parent Merger is intended to constitute a “reorganization” within the meaning of Section 368(a) of the Code. The parties hereto hereby adopt this Agreement as a “plan of reorganization” within the meaning of Treasury regulation Section 1.368-2(g).

(b) Notwithstanding anything in this Agreement to the contrary, if the tax opinion referred to in Section 7.02(e) cannot be rendered (as reasonably determined by Vorys) as a result of the Parent Merger potentially failing to satisfy the “continuity of interest” requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, then Peoples shall increase the Per Share Stock Consideration (and cause a corresponding decrease in the Per Share Cash Consideration equal to the economic value of any such increase) to the minimum extent necessary to enable the relevant tax opinion to be rendered.

4.01 Forbearances of NB&T Financial. From the date hereof until the Effective Time, except as expressly contemplated or permitted by this Agreement or required by applicable law, regulation or policy of a Governmental Authority or an applicable Regulatory Order, without the prior written consent of Peoples, NB&T Financial shall not, and shall cause its Subsidiaries not to:

No party hereto shall be deemed to have breached a representation or warranty, as a consequence of the existence of any fact, event or circumstance unless such fact, circumstance or event, individually or taken together with all other facts, events or circumstances inconsistent with any representation or warranty contained in Section 5.03 or 5.04, has had or is reasonably likely to have, a Material Adverse Effect without giving any effect to any qualification as to materiality or Material Adverse Effect set forth in such representations and warranties.

5.03 Representations and Warranties of NB&T Financial. Subject to Sections 5.01 and 5.02 and except as Previously Disclosed in a section of its Disclosure Schedule, NB&T Financial hereby represents and warrants to Peoples that the following are true and correct (provided that none of the following representations and warranties shall be applicable to the Title Agency, which NB&T Financial does not deem to be, and which for purposes of this Agreement is not, a Subsidiary):

(i) NB&T Financial is a corporation duly organized, validly existing and in good standing under the laws of the State of Ohio and is duly qualified to do business and is in good standing in any foreign jurisdictions where its ownership or leasing of property or assets or the conduct of its business requires it to be so qualified. The foreign jurisdictions in which NB&T Financial conducts business are set forth in the NB&T Financial’s Disclosure Schedule. NB&T Financial is registered as a financial holding company under the BHCA.

(ii) NBTC is a national banking association duly organized and validly existing under the laws of the United States, and has all the requisite power and is duly qualified to do business and is in good standing in any foreign jurisdictions where its ownership or leasing of property or assets or the conduct of its business requires it to be so qualified.

(i) As of June 30, 2014, the authorized capital stock of NB&T Financial consists of 6,000,000 NB&T Financial Common Shares and 100,000 shares of preferred stock, with no par value (“NB&T Financial Preferred Shares”). The NB&T Financial Common Shares and NB&T Financial Preferred Shares are collectively referred to herein as “NB&T Financial Shares.” As of the date hereof, there are: (A) 3,429,560 shares of NB&T Financial Common Shares issued and outstanding, including 306,683 shares held by the NB&T Financial Employee Stock Ownership Plan (the “NB&T Financial ESOP”); (B) 389,390 shares of Treasury Shares were held by NB&T Financial or otherwise owned by NB&T Financial or its Subsidiaries; and (C) 518,122 shares of NB&T Financial reserved for issuance pursuant to the NB&T Financial Option Plans (of which, collectively, options to purchase 255,122 shares are outstanding at the date hereof). No shares of NB&T Financial Preferred Shares are issued and outstanding or reserved for issuance. All of the issued and outstanding shares of NB&T Financial Shares have been duly authorized and validly issued and

With respect to each NB&T Financial Option outstanding as of the date hereof, the name of each optionee, the date of each option to purchase NB&T Financial Common Shares granted, the number of shares subject to each such option and the price at which each such option may be exercised are set forth in NB&T Financial’s Disclosure Schedule. The exercise price of each NB&T Financial Option is no less than the fair market value of a share of NB&T Financial Common Shares determined on the date of grant of such stock option (and as of any later modification thereof within the meaning of Section 409A of the Code). Each NB&T Financial Option intended to qualify as an “incentive stock option” under Section 422 of the Code has been structured to so qualify.

(iii) Except as set forth in NB&T Financial’s Disclosure Schedule, neither NB&T Financial nor any of its Subsidiaries have any authorized, issued, or outstanding bonds, debentures, notes or other indebtedness for which the holders thereof have the right to vote on any matters on which the shareholders have the right to vote. There are no registration rights, and there is no voting trust, proxy, rights agreement, “poison pill” anti-takeover plan or other agreement or understanding to which NB&T Financial is a party or by which it is bound with respect to any equity security of any class of NB&T Financial or with respect to any equity security, partnership interest or similar ownership interest of any class of any of its Subsidiaries.

(iii) Except as set forth on NB&T Financial’s Disclosure Schedule, neither NB&T Financial nor its Subsidiaries own beneficially, directly or indirectly, any equity securities or similar interests of any Person, or any interest in a partnership or joint venture of any kind.

(b) Except in the case of an Acceptance of Superior Proposal permitted by Section 6.06, NB&T Financial shall solicit, and use its reasonable best efforts to obtain, the NB&T Financial Shareholder Adoption at the NB&T Financial Meeting. Subject to Section 6.06(d), NB&T Financial shall (i) through the NB&T Financial Board, recommend to its shareholders adoption of this Agreement (the “NB&T Financial Recommendation”), and (ii) include such recommendation in the Joint Proxy Statement/Prospectus. In connection with the requirements of this Section, NB&T Financial shall cause an independent entity to be appointed as the trustee of, or fiduciary with respect to, the NB&T Financial ESOP (the “Independent Trustee”).

Peoples and NB&T Financial shall use their commercially reasonable best efforts to have the Registration Statement declared effective by the SEC as soon as practicable after the filing thereof. The parties shall cooperate in responding to and considering any questions or comments from the SEC staff regarding the information contained in the Registration Statement. If at any time after the Registration Statement is filed with the SEC, and prior to the Effective Time, any event relating to NB&T Financial or Peoples is discovered by NB&T Financial or Peoples, as applicable, which should be set forth in an amendment of, or a supplement to, the Registration Statement, the discovering party shall promptly inform the other party with all relevant information relating to such event, whereupon Peoples shall promptly cause an appropriate amendment to the Registration Statement to be filed with the SEC. Upon the effectiveness of such amendment, each of NB&T Financial and Peoples (if prior to the meetings of the shareholders pursuant to Section 6.02 hereof) will take all necessary action as promptly as practicable to permit an appropriate amendment or supplement to be transmitted to the shareholders entitled to vote at such meetings. Peoples shall also use reasonable best efforts to obtain all necessary state securities law or “blue sky” permits and approvals required to carry out the transactions contemplated by this Agreement, and NB&T Financial shall furnish all information concerning NB&T Financial and the holders of NB&T Financial Common Stock as may be reasonably requested in connection with any such action. NB&T Financial and Peoples shall each furnish the other with all information concerning each other and its directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Registration Statement.

(b) Peoples and NB&T Financial each agrees to use its commercially reasonable efforts and to cooperate with the other party in all reasonable respects to prepare the Joint Proxy Statement/Prospectus for filing with the SEC and, when the Registration Statement is effective, for delivery to its respective shareholders.

(c) If either party becomes aware prior to the Effective Time of any information that would cause any of the statements in the Joint Proxy Statement/Prospectus to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, that party shall promptly inform the other thereof and take the necessary steps to correct the Joint Proxy Statement/Prospectus.

6.04 Press Releases. Upon the execution of this Agreement, Peoples and NB&T Financial shall issue a joint press release regarding this Agreement and the transactions contemplated hereby, which joint press release shall be subject to the prior approval of Peoples and NB&T Financial. Neither NB&T Financial nor Peoples will, without the prior approval of the other party, issue any other press release or written statement for general circulation relating to the transactions contemplated hereby, except as otherwise may be required by applicable law or regulation before such consent can be obtained.

(a) Upon reasonable notice and subject to applicable laws relating to the exchange of information, each of NB&T Financial and Peoples shall, and shall cause each of its Subsidiaries to, afford Representatives of the other party, reasonable access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments and records, and shall cause its Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement and other documents filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking or insurance laws, and (ii) all other information concerning its business, properties and personnel as the other party

NB&T Financial shall invite one Representative of Peoples selected by Peoples from time to time to attend, solely as observer, all meetings of the NB&T Financial Board (and committees thereof) and NBTC board after the date of this Agreement; provided, however, that in no event shall such Peoples Representative be invited to or permitted to attend any executive session of NB&T Financial’s or NBTC’s board, any meeting at which NB&T Financial reasonably determines that such attendance is inconsistent with the fiduciary obligations or confidentiality requirements of the NB&T Financial Board or NBTC board, as applicable, or any meeting or part of a meeting at which the transactions contemplated by this Agreement are to be discussed. Neither NB&T Financial nor Peoples, nor any of their Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege of such party or its Subsidiaries, contravene any law, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement, or relating to its directors’, officers’, employees’, agents’, investment bankers’ or financial advisors’ consideration or deliberation of the transactions contemplated hereby or an Acquisition Proposed.

(b) Neither NB&T Financial nor Peoples will, nor shall either party’s Representatives, use any information obtained pursuant to this Section 6.05 (as well as any other information obtained prior to the date hereof in connection with the entering into of this Agreement) for any purpose unrelated to the consummation of the transactions contemplated by this Agreement, and such information will be subject to the confidentiality provisions of Section 6.16.

(c) In the event that this Agreement is terminated or the transactions contemplated by this Agreement shall otherwise fail to be consummated, each party shall promptly cause all copies of documents or extracts thereof containing information and data as to another party hereto to be returned to the party which furnished the same. No investigation by either party of the business and affairs of the other shall affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Agreement, or the conditions to either party’s obligation to consummate the transactions contemplated by this Agreement.

(d) During the period from the date of this Agreement to the Effective Time, as soon as reasonably practicable after they become available, but in no event more than 30 days after the end of each calendar month ending after the date hereof, each of NB&T Financial and Peoples will furnish to the other (i) its consolidated financial statements (including balance sheets, statements of operations and stockholders’ equity) to the extent available as of and for such month then ended, (ii) internal management reports showing actual financial performance against plan and previous period, and (iii) to the extent permitted by applicable law, any reports provided to the NB&T Financial Board or the Peoples Board or any committee thereof relating to the financial performance and risk management of the company or any of its Subsidiaries.

(a) From the date of this Agreement through the first to occur of the Effective Time or the termination of this Agreement, NB&T Financial shall not, and shall cause any of its Subsidiaries and the officers, directors, employees, advisors and other agents of NB&T Financial and its Subsidiaries not to, directly or indirectly (i) solicit, initiate, encourage, facilitate (including by way of providing information) or induce any inquiry, proposal or offer with respect to, or the making or completion of, any Acquisition Proposal, or any inquiry, proposal or offer that is reasonably likely to lead to any Acquisition Proposal, (ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person or Group any confidential or nonpublic information with respect to or in connection with, an Acquisition Proposal, (iii) take any other action intended to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to an Acquisition Proposal, (iv) approve, endorse or recommend, or propose to approve, endorse or recommend any Acquisition Proposal or any agreement related thereto, (v) enter into any agreement contemplating or otherwise relating to any Acquisition Transaction or Acquisition Proposal, (vi) enter into any agreement or agreement in principle requiring, directly or indirectly, NB&T Financial to abandon, terminate or fail to consummate the transactions contemplated hereby or breach its obligations hereunder, or (vii) propose or agree to do any of the foregoing.

(b) Notwithstanding anything to the contrary in Section 6.06(a), if NB&T Financial or any of its Representatives receives an unsolicited bona fide Acquisition Proposal that did not result from or arise in connection with a breach of Section 6.06(a), NB&T Financial and its Representatives may take any action described in Section 6.06(a)(ii), if, and only if, the NB&T Financial Board determines in good faith, after consultation with NB&T Financial’s outside legal and financial advisors, that (i) such Acquisition Proposal constitutes or is reasonably capable of becoming a Superior Proposal, and (ii) the failure to take such action would cause the NB&T Financial Board to violate its fiduciary duties to the shareholders of NB&T Financial under applicable Law; provided, that NB&T Financial receives from such Person or Group an executed confidentiality agreement containing terms no less favorable to NB&T Financial than the confidentiality terms of this Agreement.

(c) As promptly as practicable (but in no event more than two business days) following receipt of any Acquisition Proposal or any request for nonpublic information or inquiry that would reasonably be expected to lead to any Acquisition Proposal, NB&T Financial shall (i) advise Peoples in writing of the receipt of any Acquisition Proposal, request or inquiry and the terms and conditions of such Acquisition Proposal, request or inquiry, (ii) shall promptly provide to Peoples a written summary of the material terms of such Acquisition Proposal, request or inquiry including the identity of the Person or Group making the Acquisition Proposal, and (iii) shall keep Peoples promptly apprised of any related developments, discussions and negotiations (including providing Peoples with a copy of all material documentation and correspondence relating thereto) on a current basis. NB&T Financial agrees that it shall simultaneously provide to Peoples any information concerning NB&T Financial that may be provided (pursuant to Section 6.06(b)) to any other Person or Group in connection with any Acquisition Proposal which has not previously been provided to Peoples.

(d) Notwithstanding anything herein to the contrary, at any time prior to the NB&T Financial Meeting, NB&T Financial may accept or approve a Superior Proposal and withdraw its recommendation of this Agreement (“Acceptance of Superior Proposal”) and terminate this Agreement, if and only if (x) from and after the date hereof, NB&T Financial has complied with Sections 6.02 and 6.06, and (y) the Board of Directors of NB&T Financial has determined in good faith, after consultation with outside legal counsel, that the failure to take such action would cause it to violate its fiduciary duties under applicable law; provided, that the NB&T Financial Board may not effect a Acceptance of Superior Proposal unless:

(i) NB&T Financial shall have received an unsolicited bona fide written Acquisition Proposal and the NB&T Financial Board shall have concluded in good faith (after consultation with NB&T Financial’s financial advisors and outside legal counsel) that such Acquisition Proposal is a Superior Proposal, after taking into account any amendment or modification to this Agreement agreed to or proposed by Peoples;

(ii) NB&T Financial shall have provided prior written notice to Peoples at least five business days in advance (the “Notice Period”) of taking such action, which notice shall advise Peoples that the NB&T Financial Board has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal (including the identity of the Person or Group making the Superior Proposal);

(iii) during the Notice Period, NB&T Financial shall, and shall cause its financial advisors and outside counsel to, negotiate with Peoples in good faith (to the extent Peoples desires to so negotiate) to make such adjustments to the terms and conditions of this Agreement so that such Superior Proposal ceases to constitute a Superior Proposal; and

(iv) the NB&T Financial Board shall have concluded in good faith (after consultation with NB&T Financial’s financial advisors and outside legal counsel) that, after considering the results of such negotiations and giving effect to any proposals, amendments or modifications offered or agreed to by Peoples, if any, that such Acquisition Proposal continues to constitute a Superior Proposal.

If during the Notice Period any material revisions are made to the Superior Proposal, NB&T Financial shall deliver a new written notice to Peoples giving rise to a new three business day Notice Period and shall again comply with the requirements of this Section 6.06(d) with respect to such new written notice.

(e) Nothing contained in this Agreement shall prevent the NB&T Financial or the NB&T Board from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act.

(i) “Superior Proposal” means any bona fide written Acquisition Proposal on terms which the NB&T Financial Board determines in good faith, after consultation with NB&T Financial’s outside legal counsel and independent financial advisors, and taking into account all the legal, financial, regulatory and other aspects of such Acquisition Proposal, including execution risk and risks as to certainty and timing of consummation, would, if consummated, result in a transaction that is more favorable to the holders of NB&T Financial Common Shares from a financial point of view than the terms of this Agreement (in each case, taking into account any revisions to this Agreement made or proposed by Peoples); provided that for purposes of the definition of “Superior Proposal,” the references to “20% or more” in the definition of Acquisition Proposal or Acquisition Transaction shall be deemed to be references to “50% or more.”

(ii) “Acquisition Proposal” means any proposal, offer, inquiry, or indication of interest (whether binding or non-binding, and whether communicated to NB&T Financial or publicly announced to NB&T Financial ‘s shareholders) by any Person or Group (in each case other than Peoples or any of its Affiliates) relating to an Acquisition Transaction involving NB&T Financial or any of its present or future consolidated Subsidiaries, or any combination of such Subsidiaries, the purchase assets of which constitute 20% or more of the consolidated assets of NB&T Financial as reflected on NB&T Financial’s consolidated statement of condition prepared in accordance with generally accepted accounting principles.

(iii) “Acquisition Transaction” means any transaction or series of related transactions (other than the transactions contemplated by this Agreement) involving (i) any acquisition (whether direct or indirect, including by way of merger, share exchange, consolidation, business combination or other similar transaction) or purchase from NB&T Financial by any Person or “group” (as such term is defined in Section 13(d) under the Exchange Act), other than Peoples or any of its affiliates, of 20% or more in interest of the total outstanding voting securities of NB&T Financial or any of its Subsidiaries (measured by voting power), or any tender offer or exchange offer that if consummated would result in any Person or Group, other than Peoples or any of its affiliates, beneficially owning 20% or more in interest of the total outstanding voting securities of NB&T Financial or any of its Subsidiaries (measured by voting power), or any merger, consolidation, share exchange, business combination or similar transaction involving NB&T Financial pursuant to which the shareholders of NB&T Financial immediately preceding such transaction would hold less than 50% of the equity interests in the surviving or resulting entity of such transaction (or, if applicable, the ultimate parent thereof) (measured by voting power), (ii) any sale or lease or exchange, transfer, license, acquisition or disposition of a business, deposits or assets that constitute 20% or more of the consolidated assets, business, revenues, net income, assets or deposits of NB&T Financial, or (iii) any liquidation or dissolution of NB&T Financial or any of its Subsidiaries.

6.07 Takeover Laws. No party hereto shall take any action that would cause the transactions contemplated by this Agreement or the Voting Agreement to become subject to requirements imposed by the Takeover Laws and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) this Agreement, the Voting Agreement and the transactions contemplated by this Agreement from or, if necessary, challenge the validity or applicability of, the Takeover Laws, as now or hereafter in effect.

6.08 Certain Policies. Before the Effective Time, NB&T Financial shall, upon the request of Peoples, (i) modify and change its loan, investment portfolio, asset liability management and real estate valuation policies and practices (including, but not limited to, loan classifications and levels of reserves) so that such policies and practices may be applied on a basis that is consistent with those of Peoples, and (ii) evaluate the need for any reserves including, but not limited to, reserves relating to any outstanding litigation, any Tax audits or any

liabilities to be incurred upon cancellation of any contracts as a result of the Merger; provided, however, that NB&T Financial shall not be obligated to take any such action pursuant to this Section 6.08 unless and until Peoples irrevocably acknowledges that all conditions to its obligation to consummate the Merger have been satisfied (including, but not limited to, the receipt of the regulatory approvals required by Section 7.01(b) and Peoples Shareholder Approval), irrevocably certifies to NB&T Financial that Peoples’ representations and warranties, subject to Section 5.02, are true and correct as of such date and that Peoples is otherwise in material compliance with this Agreement and irrevocably waives in writing any and all rights that it may have to terminate this Agreement; provided further, however, that NB&T Financial shall not be obligated to take any such action pursuant to this Section 6.08 if such action would be inconsistent with GAAP. NB&T Financial’s representations, warranties and covenants contained in this Agreement shall not be deemed to be untrue or breached in any respect for any purpose as a consequence of any modifications or changes undertaken solely on account of this Section 6.08.

(a) Peoples and NB&T Financial and their respective Subsidiaries shall cooperate and use their respective reasonable best efforts to allow Peoples to prepare, submit and file all applications and requests for regulatory approval, to timely effect all filings and to obtain all consents, approvals and/or authorizations of all the Regulatory Authorities necessary to consummate the transactions contemplated by this Agreement. In exercising the rights under this Section, each of the parties hereto agrees to act reasonably and as promptly as practicable. Peoples agrees that it will consult with NB&T Financial with respect to the obtaining of all material consents, approvals and authorizations from the Regulatory Authorities necessary to consummate the transactions contemplated by this Agreement and to keep NB&T Financial apprised of the status of material matters relating to obtainment of such consents, approvals and/or authorizations from the Regulatory Authorities. NB&T Financial shall have the right to review in advance, subject to applicable laws relating to the exchange of information, all material written information submitted to the Regulatory Authorities in connection with the transactions contemplated by this Agreement. Notwithstanding the forgoing sentence, NB&T Financial shall not have any right to review and/or inspect any proprietary information submitted by Peoples to any Regulatory Authority with a request for confidential treatment, including, but not limited to any business plan and/or financial data or analysis prepared by Peoples in relation to such consents, approvals and/or authorizations from the Regulatory Authorities.

(b) NB&T Financial agrees, upon request, to furnish Peoples with all information concerning itself, NBTC, and their directors, officers and shareholders and such other matters as may be reasonably necessary, advisable and/or required in connection with any filing, notice or application made by or on behalf of Peoples or any of its Subsidiaries to any Regulatory Authority.

(i) It is understood and agreed that nothing in this Section 6.10 or elsewhere in this Agreement shall be deemed to be a contract of employment or be construed to give NB&T Financial’s or any of its Subsidiaries’ employees any rights other than as employees at will under applicable law, and NB&T Financial’s and its Subsidiaries’ employees shall not be deemed to be third-party beneficiaries of this Agreement, except as set forth in Section 6.17(a)(with respect to indemnification). Employees of NB&T Financial or any of its Subsidiaries who become employees of Peoples or any of its Subsidiaries as a result of the Merger (“Continuing Employees”) shall participate in either: (A) the Compensation and Benefit Plans as defined in Section 5.03(n)(i) (for so long as Peoples determines necessary or appropriate); or (B) the employee benefit plans sponsored by Peoples or any of its Subsidiaries for their employees (with credit for years of service with NB&T Financial and its Subsidiaries for participation and vesting purposes, to the extent such plans can be amended to permit, including credit for years of

service and for seniority under vacation and sick pay plans and programs, but subject to the eligibility and other terms of such plans). The prior sentence notwithstanding, the Continuing Employees shall become eligible to participate in Peoples’ Retirement Savings Plan effective as of the first entry date after the Effective Date by which a Continuing Employee has satisfied the age and service eligibility provisions of Peoples’ Retirement Savings Plan (taking into account their years of service with NB&T Financial and its Subsidiaries). In addition, to the extent Continuing Employees participate in a group health plan of Peoples or any of its Subsidiaries (instead of continuing to participate in a group health plan of NB&T Financial or any of its Subsidiaries), all restrictions and limitations on pre-existing conditions shall be waived to the extent the group health plan and insurance policy of Peoples or it Subsidiary permit (or may be amended to permit). In the event that Peoples terminates the group health plans(s) of NB&T Financial or any of its Subsidiaries, those former employees detailed on the Disclosure Schedule who as of the date of this Agreement are currently participating under such plan(s) as a result of the post-employment coverage rights contained within those plan(s), and not as a result of continuation coverage rights as a result of COBRA (collectively, “Eligible Retirees”), will be eligible to participate in the group health plan(s) sponsored by Peoples or any of its Subsidiaries in accordance with the terms of those plans, and all restrictions and limitations on pre-existing conditions shall be waived to the extent the group health plan and insurance policy of Peoples or it Subsidiary permit (or may be amended to permit). To the extent the initial period of coverage for any of the Continuing Employees or Eligible Retirees under any such plan sponsored by Peoples or any of its Subsidiaries is not a full 12-month period of coverage, the Continuing Employees and Eligible Retirees shall be given credit under the applicable plan for any deductibles and co-insurance payments made by them under the corresponding plan sponsored by NB&T Financial or any of its Subsidiaries during the balance of such 12-month period of coverage, provided that Peoples can obtain, in a manner reasonably satisfactory to Peoples, the necessary data and provided that the insurer agrees. In the event the insurer does not agree, Peoples shall take all action necessary to ensure that Continuing Employees and Eligible Retirees do not lose the value of their deductibles and co-insurance payments whether that be by continuing the group health plan sponsored by NB&T Financial or any of its Subsidiaries through the end of the applicable plan year or otherwise.

(ii) After the Effective Time, Peoples shall be liable for (A) all obligations for continued health coverage under COBRA with respect to each qualified beneficiary of NB&T Financial or a Subsidiary who incurs a termination on and after the Effective Time, and (B) for continued health coverage under COBRA from and after the Effective Time for each qualified beneficiary of NB&T Financial or a Subsidiary of NB&T Financial who incurs a qualifying event before the Effective Time.

(iii) Peoples shall assume and amend The National Bank and Trust Cafeteria Plan, and shall amend or adopt its own cafeteria plan as needed, consistent with Revenue Ruling 2002-32 to provide the Continuing Employees who elected health flexible spending coverage under the National Bank and Trust Cafeteria Plan with a continuation of the same level of health flexible spending coverage after the Effective Date and to enable those Continuing Employees to obtain reimbursement of medical expenses incurred at any time during the plan year containing the Effective Date, whether they continue to be covered under the group health plan(s) sponsored by NB&T Financial or any of its Subsidiaries or begin coverage under the group health plan(s) sponsored by Peoples or any of its Subsidiaries.

(iv) Prior to the Effective Date, but after the receipt of the last to be obtained of the NB&T Financial Shareholder Adoption, the Peoples Shareholder Adoption and the regulatory approvals required by Section 7.01(b) of this Agreement, the NB&T Financial Board shall take any action necessary to terminate coverage for any former employees under the NB&T Financial or Subsidiary health plan except for coverage provided to Eligible Retirees and/or any individual being provided coverage in accordance with COBRA.

(v) Prior to the Effective Date, NB&T Financial shall obtain waivers and consents from the current holders of NB&T Financial Options issued under the InterCounty Bancshares, Inc.

Nonqualified Stock Option Plan. Those waivers and consents shall permit the cancellation and termination of all obligations arising under the terms of the NB&T Financial Options in exchange for the consideration to be paid with respect to such NB&T Financial Options pursuant to Section 3.04 of this Agreement.

(i) Peoples shall pay to each employee of NB&T Financial or its Subsidiaries who (A) is not subject to an existing contract providing for severance and/or a change in control payment, (B) is an employee of NB&T Financial or any of its Subsidiaries immediately before the Effective Time, (C) has been an employee of NB&T Financial or any of its Subsidiaries for at least six months prior to the Effective Time, and (D) is not offered continued employment by Peoples or any of its Subsidiaries after the Effective Time at a location within 25 miles of such employee’s current normal place of employment at a salary or hourly wage not less than his or her current salary for at least 12 months after the Effective Date, a severance amount equal to two weeks’ base pay multiplied by the number of whole years of service of such employee with NB&T Financial or any of its Subsidiaries, less applicable local, state and federal tax withholding; provided, however, that the minimum severance payment shall equal four weeks of base pay, and the maximum severance payment shall not exceed 26 weeks of base pay. Such severance pay shall be paid in a lump sum within 14 days following the employee’s termination, provided that such employee has not been terminated for cause. For any employee of NB&T Financial or its Subsidiaries participating in NB&T Financial’s group health program at the Effective Time who is entitled to a severance payment, the employee will be able to purchase health insurance coverage at the employee premium rate for the first 12 months and the full premium rate for the remaining COBRA period.

(ii) In exchange for the severance pay described in Subsection (i), terminated employees will be required to execute a final and binding general release in which the employee releases and waives any and all claims the employee may have against Peoples and its Affiliates.

(iii) Peoples shall, within two business days after the Effective Time, make all payments required to be made pursuant to the employment, severance or change in control agreements set forth in NB&T Financial’s Disclosure Schedule.

(c) NB&T Financial 401(k) Plan. Prior to the Effective Date, but after the receipt of the last to be obtained of the NB&T Financial Shareholder Adoption, the Peoples Shareholder Adoption and the regulatory approvals required by Section 7.01(b) of this Agreement, the NB&T Financial Board shall: (i) take all steps as reasonably requested by Peoples to correct any Operational Failure, as such is defined in Revenue Procedure 2013-12, in connection with its and/or the applicable Subsidiary’s 401(k) Plan (the “NBTC 401(k) Plan”) which is detailed on the Disclosure Schedule; and (ii) adopt a resolution approving the termination the NBTC 401(k) Plan effective as of a date immediately preceding the Effective Date. In addition, the NB&T Financial Board shall approve the adoption of any amendments to the NBTC 401(k) Plan sufficient to terminate the NBTC 401(k) Plan immediately preceding the Effective Date and to provide for distributions in cash. Following the Effective Date, Peoples, as the successor in interest to NB&T Financial, shall begin the process of requesting from the IRS a determination that the termination of the NBTC 401(k) Plan is in compliance with Section 401(a) of the Code (the “401K Determination Letter”) and distributing benefits under the NBTC 401(k) Plan to plan participants. Peoples agrees to take all commercially reasonable steps necessary or appropriate to accept roll-overs of benefits and participant loan notes from the NBTC 401(k) Plan to the Peoples 401(k) plan for employees of NB&T Financial and its Subsidiaries who continue as employees of Peoples and its Subsidiaries after the Effective Time, subject to the provisions of the Peoples 401(k) Plan and to the extent it can be amended consistent with law to so provide.

(i) The NB&T Financial Board shall adopt a resolution approving the termination of the NB&T Financial ESOP effective as of a date immediately preceding the Effective Date.

(ii) Peoples agrees to take all commercially reasonable steps necessary or appropriate to accept roll-overs of benefits from the NB&T Financial ESOP to the Peoples 401(k) plan for employees of NB&T Financial and its Subsidiaries who continue as employees of Peoples and its Subsidiaries after the Effective Time, subject to the provisions of the NB&T Financial ESOP. Peoples further agrees to take all steps necessary to permit the in-kind direct rollover of the Peoples Common Shares held within the NB&T ESOP after the Effective Time as a result of the receipt of the Per Share Stock Consideration into the Peoples 401(k) plan; provided, however, nothing within this Agreement shall be deemed an obligation or requirement of Peoples to continue to offer the Peoples Common Shares as an investment option within the Peoples 401(k) plan at any time following the Effective Time.

Each party shall give prompt notice to one another of any fact, event or circumstance known to the disclosing party that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to the disclosing party or any of its Subsidiaries, or (ii) would cause or constitute a material breach of any of the disclosing party’s representations, warranties, covenants or agreements contained herein, or (iii) necessary to provide material updates or corrections to disclosures set forth in the party’s Disclosure Schedule or to information provided pursuant to a specific requirement of this Agreement.

I have either sought such guidance of counsel or determined after reviewing the Agreement carefully that I will waive such right.

Dissenters’ Rights Under Section 1701.85 of the Ohio General Corporation Law

1701.85 Dissenting shareholders – compliance with section – fair cash value of shares.

(A)(1) A shareholder of a domestic corporation is entitled to relief as a dissenting shareholder in respect of the proposals described in sections 1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with this section.

(2) If the proposal must be submitted to the shareholders of the corporation involved, the dissenting shareholder shall be a record holder of the shares of the corporation as to which the dissenting shareholder seeks relief as of the date fixed for the determination of shareholders entitled to notice of a meeting of the shareholders at which the proposal is to be submitted, and such shares shall not have been voted in favor of the proposal.

(3) Not later than 20 days before the date of the meeting at which the proposal will be submitted to the shareholders, the corporation may notify the corporation’s shareholders that relief under this section is available. The notice shall include or be accompanied by all of the following:

(b) A statement that the proposal can give rise to rights under this section if the proposal is approved by the required vote of the shareholders;

(c) A statement that the shareholder will be eligible as a dissenting shareholder under this section only if the shareholder delivers to the corporation a written demand with the information provided for in division (A)(4) of this section before the vote on the proposal will be taken at the meeting of the shareholders and the shareholder does not vote in favor of the proposal.

(4) If the corporation delivers notice to its shareholders as provided in division (A)(3) of this section, a shareholder electing to be eligible as a dissenting shareholder under this section shall deliver to the corporation before the vote on the proposal is taken a written demand for payment of the fair cash value of the shares as to which the shareholder seeks relief. The demand for payment shall include the shareholder’s address, the number and class of such shares, and the amount claimed by the shareholder as the fair cash value of the shares.

(5) If the corporation does not notify the corporation’s shareholders pursuant to division (A)(3) of this section, not later than ten days after the date on which the vote on the proposal was taken at the meeting of the shareholders, the dissenting shareholder shall deliver to the corporation a written demand for payment to the dissenting shareholder of the fair cash value of the shares as to which the dissenting shareholder seeks relief, which demand shall state the dissenting shareholder’s address, the number and class of such shares, and the amount claimed by the dissenting shareholder as the fair cash value of the shares.

(6) If a signatory, designated and approved by the dissenting shareholder, executes the demand, then at any time after receiving the demand, the corporation may make a written request that the dissenting shareholder provide evidence of the signatory’s authority. The shareholder shall provide the evidence within a reasonable time but not sooner than 20 days after the dissenting shareholder has received the corporation’s written request for evidence.

(7) The dissenting shareholder entitled to relief under division (A)(3) of section 1701.84 of the Revised Code in the case of a merger pursuant to section 1701.80 of the Revised Code and a dissenting shareholder entitled to relief under division (A)(5) of section 1701.84 of the Revised Code in the case of a merger pursuant to section 1701.801 of the Revised Code shall be a record holder of the shares of the corporation as to which the

dissenting shareholder seeks relief as of the date on which the agreement of merger was adopted by the directors of that corporation. Within 20 days after the dissenting shareholder has been sent the notice provided in section 1701.80 or 1701.801 of the Revised Code, the dissenting shareholder shall deliver to the corporation a written demand for payment with the same information as that provided for in division (A)(4) of this section.

(8) In the case of a merger or consolidation, a demand served on the constituent corporation involved constitutes service on the surviving or the new entity, whether the demand is served before, on, or after the effective date of the merger or consolidation. In the case of a conversion, a demand served on the converting corporation constitutes service on the converted entity, whether the demand is served before, on, or after the effective date of the conversion.

(9) If the corporation sends to the dissenting shareholder, at the address specified in the dissenting shareholder’s demand, a request for the certificates representing the shares as to which the dissenting shareholder seeks relief, the dissenting shareholder, within 15 days from the date of the sending of such request, shall deliver to the corporation the certificates requested so that the corporation may endorse on them a legend to the effect that demand for the fair cash value of such shares has been made. The corporation promptly shall return the endorsed certificates to the dissenting shareholder. A dissenting shareholder’s failure to deliver the certificates terminates the dissenting shareholder’s rights as a dissenting shareholder, at the option of the corporation, exercised by written notice sent to the dissenting shareholder within 20 days after the lapse of the 15-day period, unless a court for good cause shown otherwise directs. If shares represented by a certificate on which such a legend has been endorsed are transferred, each new certificate issued for them shall bear a similar legend, together with the name of the original dissenting holder of the shares. Upon receiving a demand for payment from a dissenting shareholder who is the record holder of uncertificated securities, the corporation shall make an appropriate notation of the demand for payment in its shareholder records. If uncertificated shares for which payment has been demanded are to be transferred, any new certificate issued for the shares shall bear the legend required for certificated securities as provided in this paragraph. A transferee of the shares so endorsed, or of uncertificated securities where such notation has been made, acquires only the rights in the corporation as the original dissenting holder of such shares had immediately after the service of a demand for payment of the fair cash value of the shares. A request under this paragraph by the corporation is not an admission by the corporation that the shareholder is entitled to relief under this section.

(B) Unless the corporation and the dissenting shareholder have come to an agreement on the fair cash value per share of the shares as to which the dissenting shareholder seeks relief, the dissenting shareholder or the corporation, which in case of a merger or consolidation may be the surviving or new entity, or in the case of a conversion may be the converted entity, within three months after the service of the demand by the dissenting shareholder, may file a complaint in the court of common pleas of the county in which the principal office of the corporation that issued the shares is located or was located when the proposal was adopted by the shareholders of the corporation, or, if the proposal was not required to be submitted to the shareholders, was approved by the directors. Other dissenting shareholders, within that three-month period, may join as plaintiffs or may be joined as defendants in any such proceeding, and any two or more such proceedings may be consolidated. The complaint shall contain a brief statement of the facts, including the vote and the facts entitling the dissenting shareholder to the relief demanded. No answer to a complaint is required. Upon the filing of a complaint, the court, on motion of the petitioner, shall enter an order fixing a date for a hearing on the complaint and requiring that a copy of the complaint and a notice of the filing and of the date for hearing be given to the respondent or defendant in the manner in which summons is required to be served or substituted service is required to be made in other cases. On the day fixed for the hearing on the complaint or any adjournment of it, the court shall determine from the complaint and from evidence submitted by either party whether the dissenting shareholder is entitled to be paid the fair cash value of any shares and, if so, the number and class of such shares. If the court finds that the dissenting shareholder is so entitled, the court may appoint one or more persons as appraisers to receive evidence and to recommend a decision on the amount of the fair cash value. The appraisers have power and authority specified in the order of their appointment. The court thereupon shall make a finding as to the fair cash value of a share and shall render judgment against the corporation for the payment of it, with interest at a

rate and from a date as the court considers equitable. The costs of the proceeding, including reasonable compensation to the appraisers to be fixed by the court, shall be assessed or apportioned as the court considers equitable. The proceeding is a special proceeding and final orders in it may be vacated, modified, or reversed on appeal pursuant to the Rules of Appellate Procedure and, to the extent not in conflict with those rules, Chapter 2505 of the Revised Code. If, during the pendency of any proceeding instituted under this section, a suit or proceeding is or has been instituted to enjoin or otherwise to prevent the carrying out of the action as to which the shareholder has dissented, the proceeding instituted under this section shall be stayed until the final determination of the other suit or proceeding. Unless any provision in division (D) of this section is applicable, the fair cash value of the shares that is agreed upon by the parties or fixed under this section shall be paid within 30 days after the date of final determination of such value under this division, the effective date of the amendment to the articles, or the consummation of the other action involved, whichever occurs last. Upon the occurrence of the last such event, payment shall be made immediately to a holder of uncertificated securities entitled to payment. In the case of holders of shares represented by certificates, payment shall be made only upon and simultaneously with the surrender to the corporation of the certificates representing the shares for which the payment is made.

(C)(1) If the proposal was required to be submitted to the shareholders of the corporation, fair cash value as to those shareholders shall be determined as of the day prior to the day on which the vote by the shareholders was taken and, in the case of a merger pursuant to section 1701.80 or 1701.801 of the Revised Code, fair cash value as to shareholders of a constituent subsidiary corporation shall be determined as of the day before the adoption of the agreement of merger by the directors of the particular subsidiary corporation. The fair cash value of a share for the purposes of this section is the amount that a willing seller who is under no compulsion to sell would be willing to accept and that a willing buyer who is under no compulsion to purchase would be willing to pay, but in no event shall the fair cash value of a share exceed the amount specified in the demand of the particular shareholder. In computing fair cash value, both of the following shall be excluded:

(a) Any appreciation or depreciation in market value resulting from the proposal submitted to the directors or to the shareholders ;

(b) Any premium associated with control of the corporation, or any discount for lack of marketability or minority status.

(2) For the purposes of this section, the fair cash value of a share that was listed on a national securities exchange at any of the following times shall be the closing sale price on the national securities exchange as of the applicable date provided in division (C)(1) of this section:

(b) Immediately before the filing of an amendment to the articles of incorporation as described in division (A) of section 1701.74 of the Revised Code;

(D)(1) The right and obligation of a dissenting shareholder to receive fair cash value and to sell such shares as to which the dissenting shareholder seeks relief, and the right and obligation of the corporation to purchase such shares and to pay the fair cash value of them terminates if any of the following applies:

(a) The dissenting shareholder has not complied with this section, unless the corporation by its directors waives such failure;

(b) The corporation abandons the action involved or is finally enjoined or prevented from carrying it out, or the shareholders rescind their adoption of the action involved;

(c) The dissenting shareholder withdraws the dissenting shareholder’s demand, with the consent of the corporation by its directors;

(d) The corporation and the dissenting shareholder have not come to an agreement as to the fair cash value per share, and neither the shareholder nor the corporation has filed or joined in a complaint under division (B) of this section within the period provided in that division.

(2) For purposes of division (D)(1) of this section, if the merger, consolidation, or conversion has become effective and the surviving, new, or converted entity is not a corporation, action required to be taken by the directors of the corporation shall be taken by the partners of a surviving, new, or converted partnership or the comparable representatives of any other surviving, new, or converted entity.

(E) From the time of the dissenting shareholder’s giving of the demand until either the termination of the rights and obligations arising from it or the purchase of the shares by the corporation, all other rights accruing from such shares, including voting and dividend or distribution rights, are suspended. If during the suspension, any dividend or distribution is paid in money upon shares of such class or any dividend, distribution, or interest is paid in money upon any securities issued in extinguishment of or in substitution for such shares, an amount equal to the dividend, distribution, or interest which, except for the suspension, would have been payable upon such shares or securities, shall be paid to the holder of record as a credit upon the fair cash value of the shares. If the right to receive fair cash value is terminated other than by the purchase of the shares by the corporation, all rights of the holder shall be restored and all distributions which, except for the suspension, would have been made shall be made to the holder of record of the shares at the time of termination.

You have requested the opinion of Keefe, Bruyette & Woods, Inc. (“KBW” or “we”) as investment bankers as to the fairness, from a financial point of view, to the common shareholders of NB&T Financial Group, Inc. (“NBTF”) of the Merger Consideration (as defined below) in the proposed merger (the “Transaction”) of NBTF with and into Peoples Bancorp Inc. (“PEBO”), pursuant to the Agreement and Plan of Merger to be entered into by and between NBTF and PEBO (the “Agreement”). Pursuant to the terms of the Agreement and subject to the terms, conditions and limitations set forth therein, at the Effective Time (as defined in the Agreement), by virtue of the Transaction and without any action on the part of the holders of shares of common stock, without par value, of NBTF (the “NBTF Common Stock”), each share of NBTF Common Stock that is issued and outstanding immediately prior to the Effective Time (other than Treasury Shares and Dissenting Shares (each as defined in the Agreement) shall be converted into the right to receive: (i) 0.9319 shares of common stock, without par value, of PEBO (the “PEBO Common Stock”) (the “Stock Consideration”) and (ii) an amount of cash equal to $7.75 (the “Cash Consideration”). The Stock Consideration and the Cash Consideration are referred to collectively herein as the “Merger Consideration.” The terms and conditions of the Transaction are more fully set forth in the Agreement.

In addition, as more fully described in the Agreement and by representatives of NBTF and PEBO, PEBO will effect the following issuances of PEBO Common Stock (which are referred to collectively herein as the “PEBO Equity Issuances”): (i) PEBO will issue approximately 2,100,000 shares of PEBO Common Stock, in the aggregate, as consideration to be paid in connection with the acquisitions by PEBO of (A) Ohio Heritage Bancorp, Inc. (“OHHB”) that was publicly announced on April 4, 2014 (the “OHHB Acquisition”) and (B) North Akron Savings Bank (“North Akron”) that was publically announced on April 21, 2014 (the “North Akron Acquisition”), which acquisitions we have been advised by representatives of PEBO are expected to close in the third and fourth quarters of 2014, respectively, and (ii) subsequent to the public announcement of the Transaction and prior to the consummation of the Transaction, PEBO will issue approximately 1,800,000 shares of PEBO Common Stock in a PIPE offering for aggregate gross proceeds of up to approximately $42.5 million. For purposes of our opinion and at the direction of the Board (as defined below), we have assumed the occurrence of the PEBO Equity Issuances in all respects material to our analyses. The Agreement further provides that, following the Effective Time, National Bank and Trust Company, a wholly-owned subsidiary of NBTF, will merge with and into Peoples Bank, National Association, a wholly-owned subsidiary of PEBO (such transaction, the “Bank Merger”).

KBW has acted as financial advisor to NBTF and not as an advisor to or agent of any other person. As part of our investment banking business, we are continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, we have experience in, and knowledge of, the valuation of banking enterprises. Further to existing sales and trading relationships between KBW and each of NBTF and PEBO, we have from time to time, in the ordinary course of our business as a broker-dealer purchased securities from and sold

securities to, NBTF and PEBO, and as a market maker in securities, we may from time to time have a long or short position in, and buy or sell, debt or equity securities of NBTF and PEBO for our own account and for the accounts of our customers. To the extent we have any such position as of the date of this opinion it has been disclosed to NBTF. We have acted exclusively for the board of directors of NBTF (the “Board”) in rendering this opinion and will receive a fee from NBTF for our services. A portion of our fee is payable upon the rendering of this opinion, a portion is payable upon the signing of a definitive agreement in respect of the Transaction and a significant portion is contingent upon the successful completion of the Transaction. In addition, NBTF has agreed to indemnify us for certain liabilities arising out of our engagement.

In addition to this present engagement, KBW has provided investment banking and financial advisory services to NBTF in the past two years and received compensation for such services. KBW was engaged by NBTF in October 2013 to provide financial advisory services in connection with a proposed acquisition by NBTF that was not consummated. In the past two years, KBW has from time to time provided investment banking and financial advisory services to PEBO for which KBW did not receive compensation. As you are aware, among such services were advisory services in connection with PEBO’s prior preliminary consideration of the acquisition of NBTF, on which KBW ceased performing work in August 2013. Prior to the past two years, KBW was engaged by PEBO in May 2012 to provide financial advisory services in connection with another proposed acquisition by PEBO that was not consummated and received compensation for such services. We may in the future provide investment banking and financial advisory services to NBTF or PEBO and receive compensation for such services.

In connection with this opinion, we have reviewed, analyzed and relied upon material bearing upon the financial and operating condition of NBTF and PEBO and the Transaction, including among other things, the following: (i) a draft of the Agreement dated August 1, 2014 (the most recent draft made available to us); (ii) the audited financial statements and Annual Reports on Form 10-K for the three fiscal years ended December 31, 2013 of NBTF; (iii) the audited financial statements and Annual Reports on Form 10-K for the three fiscal years ended December 31, 2013 of PEBO; (iv) the unaudited quarterly financial statements and quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2014 for NBTF and quarterly results for June 30, 2014 ; (v) the unaudited quarterly financial statements and quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2014 for and PEBO and the quarterly results for June 30, 2014; (vi) certain regulatory filings of NBTF and PEBO, including the quarterly call reports filed with respect to each quarter during the three year period ended June 30, 2014; (vii) certain other interim reports and other communications of NBTF and PEBO to their respective stockholders; and (viii) other financial information concerning the businesses and operations of NBTF and PEBO furnished to us by NBTF and PEBO or which we were otherwise directed to use for purposes of our analysis. Our consideration of financial information and other factors that we deemed appropriate under the circumstances or relevant to our analyses included, among others, the following: (i) the historical and current financial position and results of operations of NBTF and PEBO; (ii) the assets and liabilities of NBTF and PEBO; (iii) the nature and terms of certain other merger transactions and business combinations in the banking industry; (iv) a comparison of certain financial and stock market information for NBTF and PEBO with similar information for certain other companies the securities of which are publicly traded; (v) financial and operating forecasts and projections of NBTF that were prepared by NBTF management, provided to and discussed with us by such management and used and relied upon by us at the direction of such management with the consent of the Board; (vi) publicly available consensus “street estimates” of PEBO for 2014 and 2015 (which estimates reflect the pro forma impact of the North Akron Acquisition and the OHHB Acquisition), as well as assumed long term growth rates based thereon, all of which information was discussed with us by PEBO management and used and relied upon by us at the direction of such management with the consent of the Board; (vii) projected balance sheet and capital data of PEBO (giving effect to each of the OHHB Acquisition and the North Akron Acquisition) that were reviewed by, and provided to and discussed with us by, PEBO management, and that were used and relied upon by us at the direction of such management with the consent of the Board; and (viii) estimates regarding certain pro forma financial effects of the Transaction on PEBO (including, without limitation, the cost savings, revenue enhancements and related expenses expected to result from the Transaction) that were prepared by PEBO management, provided to and discussed with us by such management and used and

relied upon by us at the direction of such management with the consent of the Board. We have also performed such other studies and analyses as we considered appropriate and have taken into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience in securities valuation and knowledge of the banking industry generally. We have also held discussions with senior management of NBTF and PEBO regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as we have deemed relevant to our inquiry. In addition, we have considered the results of the efforts undertaken by NBTF, with our assistance, to solicit indications of interest from third parties regarding a potential transaction with NBTF.

In conducting our review and arriving at our opinion, we have relied upon and assumed the accuracy and completeness of all of the financial and other information provided to us or publicly available and we have not independently verified the accuracy or completeness of any such information or assumed any responsibility or liability for such verification, accuracy or completeness. We have relied upon the management of NBTF as to the reasonableness and achievability of the financial and operating forecasts and projections of NBTF (and the assumptions and bases therefor) that were prepared by NBTF management and provided to and discussed with us by such management, and we have assumed, with the consent of NBTF, that such forecasts and projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of such management and that such forecasts and projections will be realized in the amounts and in the time periods currently estimated by such management. We have further relied, with the consent of NBTF, upon PEBO management as to the reasonableness and achievability of (i) the publicly available consensus “street estimates” of PEBO that we were directed by such management to use (including the assumed long term growth rates based thereon), (ii) the projected balance sheet and capital data of PEBO (giving effect to each of the North Akron Acquisition and the OHHB Acquisition) that were reviewed by, and provided to and discussed with us by, such management, and (iii) the estimates regarding certain pro forma financial effects of the Transaction on PEBO that were prepared by PEBO management and provided to and discussed with us by such management (and the assumptions and bases therefor, including but not limited to the cost savings, revenue enhancements and related expenses expected to result from the Transaction ). We have assumed, with the consent of the Board, that all such information is consistent with (in the case of PEBO “street estimates”), or was otherwise reasonably prepared on a basis reflecting, the best currently available estimates and judgments of such management and that the forecasts, estimates and projected data reflected in such information will be realized in the amounts and in the time periods currently estimated. We express no view or opinion herein as to the OHHB Acquisition or the North Akron Acquisition (or any terms, aspects or implications of either such transaction) and have assumed, with the consent of NBTF, that each such acquisition (including the subsidiary merger related to each acquisition) will be consummated as described to us by PEBO management in the third and fourth quarters of 2014, respectively.

It is understood that such forecasts, projections and estimates of NBTF and PEBO prepared by NBTF management and PEBO management and provided to and discussed with us were not prepared with the expectation of public disclosure, and that such forecasts, projections, and estimates, together with the publicly available consensus “street estimates” of PEBO referred to above, are based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions and that, accordingly, actual results could vary significantly from those set forth in such forecasts, projections and estimates. We have assumed, based on discussions with the respective managements of NBTF and PEBO, and at the direction of such managements and with the consent of the Board, that all such information provides a reasonable basis upon which we could form our opinion and we express no view as to any such information or the assumptions or bases therefor. We have relied on all such information without independent verification or analysis and do not in any respect assume any responsibility or liability for the accuracy of completeness thereof.

We also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either NBTF or PEBO since the date of the last financial statements of each such entity that were made available to us. We are not experts in the independent verification of the adequacy of

allowances for loan and lease losses and we have assumed, without independent verification and with your consent, that the aggregate allowances for loan and lease losses for NBTF and PEBO are adequate to cover such losses. In rendering our opinion, we have not made or obtained any evaluations or appraisals or physical inspection of the property, assets or liabilities (contingent or otherwise) of NBTF or PEBO, the collateral securing any of such assets or liabilities, or the collectability of any such assets, nor have we examined any individual loan or credit files, nor did we evaluate the solvency, financial capability or fair value of NBTF or PEBO under any state or federal laws, including those relating to bankruptcy, insolvency or other matters. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, we assume no responsibility or liability for their accuracy.

We have assumed, in all respects material to our analyses, the following: (i) that the Transaction will be completed substantially in accordance with the terms set forth in the Agreement (the final terms of which will not differ in any respect material to our analyses from the draft reviewed) with no additional payments or adjustments to the Merger Consideration; (ii) that any related transactions (including the Bank Merger and the PEBO Equity Issuances) will be substantially completed in accordance with the terms set forth in or as contemplated by the Agreement or as otherwise described to us by representatives of NBTF and PEBO and that the pending North Akron Acquisition and the OHHB Acquisition will be completed as described to us by representatives of PEBO, (iii) that the representations and warranties of each party in the Agreement and in all related documents and instruments referred to in the Agreement are true and correct; (iv) that each party to the Agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents; (v) that there are no factors that would delay or subject to any adverse conditions, any necessary regulatory or governmental approval for the Transaction, any related transaction, or PEBO’s pending North Akron Acquisition and OHHB Acquisition, and that all conditions to the completion of the Transaction and any related transaction will be satisfied without any waivers or modifications to the Agreement; and (vi) that in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the Transaction and any related transaction, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, will be imposed that will have a material adverse effect on the future results of operations or financial condition of NBTF, PEBO, the combined entity, or the contemplated benefits of the Transaction, including the cost savings, revenue enhancements and related expenses expected to result from the Transaction. We have assumed that the Transaction will be consummated in a manner that complies with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations. We have further assumed that NBTF has relied upon the advice of its counsel, independent accountants and other advisors (other than KBW) as to all legal, financial reporting, tax, accounting and regulatory matters with respect to NBTF, PEBO, the Transaction, any related transaction (including the Bank Merger and the PEBO Equity Issuances) and the Agreement. KBW has not provided advice with respect to any such matters.

This opinion addresses only the fairness, from a financial point of view, as of the date hereof, of the Merger Consideration in the Transaction to the holders of NBTF Common Stock. We express no view or opinion as to any terms or other aspects of the Transaction or any related transaction (including the Bank Merger and the PEBO Equity Issuances, including without limitation, the form or structure of the Transaction (including the form of Merger Consideration or the allocation of the Merger Consideration among cash and stock) or any related transaction, any consequences of the Transaction or any related transaction to NBTF, its stockholders, creditors or otherwise, or any terms, aspects, merits or implications of any employment, consulting, voting, support, stockholder or other agreements, arrangements or understandings contemplated or entered into in connection with the Transaction or otherwise. We further express no view or opinion herein as to either the North Akron Acquisition or the OHHB Acquisition, including without limitation any direct or indirect consequence or impact of either the consummation of any one or both acquisitions (further to either of their publicly announced terms (including anticipated timing) or otherwise) or, alternatively, the failure to consummate any one or both such acquisitions, on NBTF, PEBO, the holders of NBTF Common Stock or PEBO Common Stock, the Transaction (including any term or aspect thereof) or any

related transaction, or the prices, trading range or volume of NBTF Common Stock or PEBO Common Stock. Our opinion is necessarily based upon conditions as they exist and can be evaluated on the date hereof and the information made available to us through the date hereof. It is understood that subsequent developments may affect the conclusion reached in this opinion and that KBW does not have an obligation to update, revise or reaffirm this opinion. Our opinion does not address, and we express no view or opinion with respect to, (i) the underlying business decision of NBTF to engage in the Transaction or enter into the Agreement, (ii) the relative merits of the Transaction as compared to any strategic alternatives that are, have been or may be available to or contemplated by NBTF or the Board, (iii) the fairness of the amount or nature of any compensation to any of NBTF’s officers, directors or employees, or any class of such persons, relative to any compensation to the holders of NBTF Common Stock, (iv) the effect of the Transaction or any related transaction on, or the fairness of the consideration to be received by, holders of any class of securities of NBTF other than the NBTF Common Stock (solely with respect to the Merger Consideration, as described herein and not relative to the consideration to be received by any other class) or any class of securities of PEBO or any other party to any transaction contemplated by the Agreement, (v) any adjustments (as provided in the Agreement) to the amount of Cash Consideration or Stock Consideration contemplated hereby, (vi) whether PEBO has sufficient cash, available lines of credit or other sources of funds to enable it to pay the aggregate Cash Consideration to the holders of NBTF Common Stock at the closing of the Transaction, (vii) the actual value of PEBO Common Stock to be issued in the Transaction, (viii) the prices, trading range or volume at which NBTF Common Stock or PEBO Common Stock will trade following the public announcement of the Transaction or the prices, trading range or volume at which PEBO Common Stock will trade following consummation of the Transaction, (ix) any advice or opinions provided by any other advisor to any of the parties to the Transaction or any other transaction contemplated by the Agreement, or (x) any legal, regulatory, accounting, tax or similar matters relating to NBTF, PEBO, their respective stockholders, or relating to or arising out of or as a consequence of the Transaction or any related transaction (including the Bank Merger and the PEBO Equity Issuances), including whether or not the Transaction would qualify as a tax-free reorganization for United States federal income tax purposes.

This opinion is for the information of, and is directed to, the Board (in its capacity as such) in connection with its consideration of the financial terms of the Transaction. This opinion is not to be used for any other purpose and may not be published, referred to, reproduced, disseminated or quoted from, in whole or in part, nor shall any public reference to KBW be made, without our prior written consent. This opinion does not constitute a recommendation to the Board as to how it should vote on the Transaction, or to any holder of NBTF Common Stock or any shareholder of any other entity as to how to vote in connection with the Transaction or any other matter, nor does it constitute a recommendation as to whether or not any such shareholder should enter into a voting, shareholders’, or affiliates’ agreement with respect to the Transaction or exercise any dissenters’ or appraisal rights that may be available to such shareholder.

This opinion has been reviewed and approved by our Fairness Opinion Committee in conformity with our policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Merger Consideration in the Transaction is fair, from a financial point of view, to the holders of NBTF Common Stock.

We understand that Peoples Bancorp Inc. (the “Company”) and NB&T Financial Group, Inc. (the “Target”) propose to enter into the Agreement (defined below) pursuant to which, among other things, the Target will be merged with and into the Company (the “Transaction”) and that, in connection with the Transaction, each outstanding share of common stock, no par value per share, of the Target (the “Common Shares”) will be converted into the right to receive $7.75 in cash and 0.9319 shares of Peoples’ common stock as more fully described in the Agreement (the “Common Share Transaction Consideration”). The Board of Directors of the Company (the “Board”) has requested that Raymond James & Associates, Inc. (“Raymond James”) provide an opinion (the “Opinion”) to the Board as to whether, as of the date hereof, the Common Share Transaction Consideration to be paid by the Company in the Transaction pursuant to the Agreement is fair from a financial point of view to the Company. For purposes of this Opinion, and with your consent, we have assumed that the Common Share Transaction Consideration is $31.00 per share.

In connection with our review of the proposed Transaction and the preparation of this Opinion, we have, among other things:

With your consent, we have assumed and relied upon the accuracy and completeness of all information supplied by or on behalf of the Company or the Target or otherwise reviewed by or discussed with us, and we have

undertaken no duty or responsibility to, nor did we, independently verify any of such information. We have not made or obtained an independent appraisal of the assets or liabilities (contingent or otherwise) of the Target. We are not experts in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for loan losses; accordingly, we have assumed that such allowances for losses are in the aggregate adequate to cover such losses. With respect to the Projections and any other information and data provided to or otherwise reviewed by or discussed with us, we have, with your consent, assumed that the Projections and such other information and data have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of management of the Company, and we have relied upon the Company to advise us promptly if any information previously provided became inaccurate or was required to be updated during the period of our review. We express no opinion with respect to the Projections or the assumptions on which they are based. We have assumed that the final form of the Agreement will be substantially similar to the draft reviewed by us, and that the Transaction will be consummated in accordance with the terms of the Agreement without waiver or amendment of any conditions thereto. Furthermore, we have assumed, in all respects material to our analysis, that the representations and warranties of each party contained in the Agreement are true and correct and that each such party will perform all of the covenants and agreements required to be performed by it under the Agreement without being waived. We have relied upon and assumed, without independent verification, that (i) the Transaction will be consummated in a manner that complies in all respects with all applicable international, federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for the consummation of the Transaction will be obtained and that no delay, limitations, restrictions or conditions will be imposed or amendments, modifications or waivers made that would have an effect on the Transaction or the Company that would be material to our analyses or this Opinion.

We have relied upon, without independent verification, the assessment of the Company’s management and its legal, tax, accounting and regulatory advisors with respect to all legal, tax, accounting and regulatory matters, including without limitation that the Transaction will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

Our opinion is based upon market, economic, financial and other circumstances and conditions existing and disclosed to us as of August 1, 2014 and any material change in such circumstances and conditions would require a reevaluation of this Opinion, which we are under no obligation to undertake. We have relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to us that would be material to our analyses or this Opinion, and that there is no information or any facts that would make any of the information reviewed by us incomplete or misleading in any material respect.

We express no opinion as to the underlying business decision to effect the Transaction, the structure or tax consequences of the Transaction or the availability or advisability of any alternatives to the Transaction. We provided advice to the Company with respect to the proposed Transaction. We did not, however, recommend any specific amount of consideration or that any specific consideration constituted the only appropriate consideration for the Transaction. This letter does not express any opinion as to the likely trading range of the Company’s or Target’s common stock following the Transaction, which may vary depending on numerous factors that generally impact the price of securities or on the financial condition of the Company or the Target at that time. Our opinion is limited to the fairness, from a financial point of view, of the Common Share Transaction Consideration to be paid by the Company.

We express no opinion with respect to any other reasons, legal, business, or otherwise, that may support the decision of the Board of Directors to approve or consummate the Transaction. Furthermore, no opinion, counsel or interpretation is intended by Raymond James on matters that require legal, accounting or tax advice. It is assumed that such opinions, counsel or interpretations have been or will be obtained from the appropriate professional sources. Furthermore, we have relied, with the consent of the Company, on the fact that the

Company has been assisted by legal, accounting and tax advisors and we have, with the consent of the Company, relied upon and assumed the accuracy and completeness of the assessments by the Company and its advisors as to all legal, accounting and tax matters with respect to the Company and the Transaction.

In formulating our opinion, we have considered only what we understand to be the consideration to be paid by the Company as is described above and we did not consider and we express no opinion on the fairness of the amount or nature of any compensation to be paid or payable to any of the Target’s officers, directors or employees, or class of such persons in connection with the Transaction. We have not been requested to opine as to, and this Opinion does not express an opinion as to or otherwise address, among other things: (1) the fairness of the Transaction to the holders of any class of securities, creditors, or other constituencies of the Company, or to any other party, except and only to the extent expressly set forth in the last sentence of this Opinion or (2) the fairness of the Transaction to any one class or group of the Company’s or any other party’s security holders or other constituencies vis-à-vis any other class or group of the Company’s or such other party’s security holders or other constituents (including, without limitation, the allocation of any consideration to be received in the Transaction amongst or within such classes or groups of security holders or other constituents). We are not expressing any opinion as to the impact of the Transaction on the solvency or viability of the Company or the Target or the ability of the Company or Target to pay their respective obligations when they come due.

The delivery of this opinion was approved by an opinion committee of Raymond James.

Raymond James has been engaged to render financial advisory services to the Company in connection with the proposed Transaction and will receive a fee for such services, a substantial portion of which is contingent upon consummation of the Transaction. Raymond James will also receive a fee upon the delivery of this Opinion, which is not contingent upon the successful completion of the Transaction or on the conclusion reached herein. In addition, the Company has agreed to reimburse certain of our expenses and to indemnify us against certain liabilities arising out of our engagement. The Company has also engaged Raymond James to assist in raising common equity; the proceeds from which will be used, in part, to finance the Transaction and Raymond James will received a fee for such services upon completion of the equity financing.

In the ordinary course of our business, Raymond James may trade in the securities of the Company and the Target for our own account or for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. Furthermore, Raymond James may provide investment banking, financial advisory and other financial services to the Company and/or Target or other participants in the Transaction in the future, for which Raymond James may receive compensation.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Common Share Transaction Consideration to be paid by the Company in the Transaction pursuant to the Agreement is fair, from a financial point of view, to the Company.
