QUESTIONS AND ANSWERS ABOUT THE MERGER

For each of your shares of First Bexley common stock, you will receive the per share merger consideration equal to $30.50 in the form of a combination of cash and shares of Parent common stock to be calculated as set forth in the Merger Agreement. Of such per share merger consideration, 20%, or $6.10, will be paid in cash and 80%, or $24.40, will be paid in Parent’s common stock (including cash to be paid in lieu of any fractional shares), subject to certain adjustment depending upon changes in the market price of Parent’s common stock. The exchange ratio used to determine the number of shares of Parent common stock that you will be entitled to receive for each share of First Bexley common stock will be determined based on the average closing price on the Nasdaq Global Select Market (“Nasdaq”) for the twenty trading days ending on the third business day prior to the effective time of the Merger (the “Parent Share Average Closing Price”), subject to a minimum and maximum price equal to $13.80 and $18.66, respectively, and certain further adjustment. Based on an Parent Share Average Closing Price of $    , which is equal to the Parent Share Average Closing Price if it were calculated as if the closing date was            , 2014, the latest practicable date prior to the date of this proxy statement/prospectus, the merger consideration that a First Bexley shareholder would be entitled to receive for each share of First Bexley common stock is $6.10 in cash and      shares of Parent common stock. If the Parent Share Average Closing Price were equal to the minimum of $13.80, each share of First Bexley common stock would instead be entitled to $6.10 in cash and 1.7681 shares of Parent common stock; if the Parent Share Average Closing Price were equal to the maximum of $18.66, each share of First Bexley common stock would be entitled to $6.10 in cash and 1.3076 shares of Parent common stock. For a description of how the merger consideration will be calculated, see “Description of the Merger Agreement — Consideration to be received in the Merger”.

In addition, the ratio or calculation of the stock component in the merger consideration may be adjusted if the Parent Share Average Closing Price is less than $13.80 or more than $18.66. For a description of the possible adjustment of the merger consideration, see “Description of the Merger Agreement — Consideration to be received in the Merger — Stock Consideration Ratio Adjustment,” “— Tax Adjustment” and “— Kill or Fill Adjustment” on page 46.

TABLE OF CONTENTS

The Merger and the Merger Agreement (See pages 24, 44 and Annex A)

First Financial’s acquisition of First Bexley is governed by the Merger Agreement. The Merger Agreement provides that, if all of the conditions set forth in the Merger Agreement are satisfied or waived, First Bexley will be merged with and into First Financial and will cease to exist. After the consummation of the Merger, First Financial will continue as the surviving bank and remain a wholly owned subsidiary of Parent. The Merger Agreement is included as Annex A to this proxy statement/prospectus and is incorporated by reference herein. We urge you to read the Merger Agreement carefully and fully, as it is the legal document that governs the Merger.

What First Bexley shareholders will receive (See page 44)

If the Merger is completed, the shares of First Bexley common stock that you own immediately before the completion of the Merger will be converted into the right to receive a combination of cash and shares of Parent common stock. All outstanding stock options of First Bexley will be cashed out at the closing of the Merger. Including payment to be made for cancelling the stock options, the fully diluted total Merger consideration is valued at approximately $44.5 million.

For each of your shares of First Bexley common stock, you will receive the per share Merger consideration equal to $30.50 in the form of a combination of cash and shares of Parent common stock to be calculated as set forth in the Merger Agreement. Of such per share merger consideration, 20%, or $6.10, will be paid in cash and 80%, or $24.40, will be paid in Parent’s common stock (including cash to be paid in lieu of any fractional shares), subject to certain adjustment depending upon changes in the market price of Parent’s common stock. The exchange ratio used to determine the number of shares of Parent common stock that you will be entitled to receive for each share of First Bexley common stock will be determined based on the average closing price on Nasdaq for the twenty trading days ending on the third business day prior to the effective time of the Merger (the “Parent Share Average Closing Price”), subject to a minimum and maximum price equal to $13.80 and $18.66 (the “Collar Restriction”), respectively, and certain further adjustment. Based on an Parent Share Average Closing Price of $     , which is equal to the Parent Share Average Closing Price if it were calculated as if the closing date was            , 2014, the latest practicable date prior to the date of this proxy statement/prospectus, the merger consideration that a First Bexley shareholder would be entitled to receive for each share of First Bexley common stock is $6.10 in cash and      shares of Parent common stock. If the Parent Share Average Closing Price were equal to the minimum of $13.80, each share of First Bexley common stock would instead be entitled to $6.10 in cash and 1.7681 shares of Parent common stock; if the Parent Share Average Closing Price were equal to the maximum of $18.66, each share of First Bexley common stock would be entitled to $6.10 in cash and 1.3076 shares of Parent common stock. For a description of how the merger consideration will be calculated, see “Description of the Merger Agreement — Consideration to be received in the Merger”.

If the Parent Share Average Closing Price has declined by more than 25% from the average closing price on Nasdaq for the twenty trading days ending on the third business day prior to the date of the Merger Agreement, which is $16.23, and the Parent common stock underperforms the KBW Regional Banking Index by more than 25% during such period, First Bexley may terminate the Merger Agreement unless Parent removes the Collar Restriction in calculating the exchange ratio for the stock component of the merger consideration.

If the Parent Share Average Closing Price is less than $13.80, First Bexley may reduce the ratio of stock component of the merger consideration from 80% to no less than 75%. On the other hand, if the Parent Share Average Closing Price is more than $18.66, First Financial may reduce the ratio of stock component of the merger consideration from 80% to no less than 75%. No such reduction is permitted if it would result in a failure of the Merger being a tax-free reorganization for United States federal income tax purposes.

In addition, in order to preserve the tax-free reorganization qualification of the Merger, if the aggregate value of the shares of Parent common stock to be issued in connection with the Merger (excluding the value of fractional shares for which cash is to be paid) based upon the closing price of the Parent common stock as reported on Nasdaq on the trading day immediately preceding the closing date of the Merger (the “Tax Adjuster Stock Consideration”) would be less than 40% of the sum of the Tax-Adjuster Cash Consideration (as defined below) and the Tax-Adjuster Stock Consideration, then the exchange ratio for the stock component

TABLE OF CONTENTS

of the merger consideration will be adjusted so that the Tax-Adjuster Stock Consideration is equal to 40% of the sum of the Tax-Adjuster Stock Consideration and the Tax-Adjuster Cash Consideration without changing the value of the total merger consideration. For purposes of the above, “Tax-Adjuster Cash Consideration” means the sum of (i) the aggregate cash consideration to be paid in exchange for the First Bexley common stock (including, without limitation, the cash paid for appraisal shares) and (ii) the aggregate cash consideration to be paid in lieu of fractional shares. Assuming the Parent Share Average Closing Price is equal to $     , each share of First Bexley common stock would be entitled to $6.10 in cash and      shares of Parent common stock; however, if the closing price of the Parent common stock as reported on Nasdaq on the trading day immediately preceding the closing date of the Merger falls below $2.30, adjustment will be made to preserve the tax-free qualification (assuming no cash paid for appraisal shares and no other adjustment made by the parties, and disregarding the effect of cash consideration to be paid in lieu of fractional shares, for purpose of illustration). For example, under these assumptions, if the above-referenced closing price of the Parent common stock falls to $2.25, each share of First Bexley common stock would be entitled to $18.30 in cash and 5.4223 shares of Parent common stock. First Bexley shareholders will not receive fractional shares of Parent common stock. Instead, they will receive a cash payment for any fractional shares based on the value of Parent common stock.

Exchange of First Bexley common stock (See page 46)

Once the Merger is complete, U.S. Bank National Association, as exchange agent, will mail you transmittal materials and instructions for exchanging your First Bexley stock certificates for shares of Parent common stock to be issued by book-entry transfer.

Material U.S. federal income tax consequences of the Merger (See page 37)

The Merger is intended to qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). As a condition to the completion of the Merger, Patton Boggs LLP, counsel to First Bexley must deliver an opinion, dated the closing date of the Merger, to the effect that the Merger will be treated as a tax-free reorganization within the meaning of Section 368(a) of the Code. Assuming the Merger qualifies as a tax-free reorganization, subject to the limitations and more detailed discussion set forth below in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger,” a First Bexley shareholder that is a U.S. holder (defined below in the section entitled “Material U.S. federal income tax consequences of the Merger”) and that exchanges all of its shares of First Bexley common stock for Parent common stock and cash pursuant to the Merger will recognize gain (but not loss), and such shareholder's taxable gain in that case will not exceed the cash received in the Merger.

Tax matters are complicated, and the tax consequences of the Merger to a particular First Bexley shareholder will depend in part on such shareholder's individual circumstances. Accordingly, you are urged to consult your own tax advisor for a full understanding of the tax consequences of the Merger to you, including the applicability and effect of federal, state, local and foreign income and other tax laws. For a more complete discussion of the material U.S. federal income tax consequences of the Merger, see the section entitled, “Material U.S. federal income tax consequences of the Merger” beginning on page 37.

TABLE OF CONTENTS

Opinion of First Bexley’s Financial Advisor (see page 29 and Annex C)

On December 17, 2013, Keefe, Bruyette & Woods, Inc. (“KBW”) rendered to the First Bexley board of directors KBW’s opinion with respect to the fairness of the merger consideration to be received by First Bexley shareholders, from a financial point of view.

KBW’s opinion is directed to the First Bexley board of directors and relates only to the fairness of the merger consideration to be received by First Bexley shareholders, from a financial point of view. KBW’s opinion does not address any other aspect of the Merger and is not a recommendation to any First Bexley shareholder as to how such shareholder should vote at the special meeting.

The full text of KBW’s December 17, 2013 opinion is included as Annex C to this proxy statement/prospectus and is incorporated by reference herein. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by KBW in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the opinion. First Bexley shareholders are urged to read the entire opinion carefully in connection with their consideration of the Merger Agreement.

Board recommendation to First Bexley’s shareholders (See page 26)

First Bexley’s board of directors believes that the Merger of First Bexley with First Financial is in the best interests of First Bexley and its shareholders. First Bexley’s board of directors unanimously recommends that you vote “FOR” the Merger.

Interests of officers and directors of First Bexley in the Merger may be different from, or in addition to, yours (See page 41)

When you consider the First Bexley board of directors’ recommendation to vote in favor of the adoption of the Merger Agreement, you should be aware that some of First Bexley’s directors and officers may have interests in the Merger that are different from, or in addition to, your interests as shareholders. First Bexley’s board of directors was aware of these interests and took them into account in approving the Merger. These interests include, among others, proposed employee benefits for those who become employees of First Financial after the Merger, the appointment of one director designated by First Bexley to serve on the board of directors of Parent (subject to the approval of Parent’s Corporate Governance and Nominating Committee), the appointment of certain First Bexley director or directors to the Columbus advisory board of Parent, and lump sum cash payments in exchange for the cancellation of outstanding First Bexley stock options.

First Financial has agreed to maintain in effect the current directors’ and officers’ liability insurance policies maintained by First Bexley or otherwise provide insurance policies of at least same coverage, subject to limits on availability and cost, for six years. First Financial and Parent have also agreed to indemnify and hold harmless the current and former directors, officers and employees of First Bexley and its subsidiaries for all actions taken by them in such capacities prior to the effective time of the Merger, and assume all obligations of First Bexley and its subsidiaries to such directors, officers and employees in respect of indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the effective time as provided in their organizational documents.

First Bexley shareholders will have appraisal rights in connection with the Merger (See page 42)

First Bexley shareholders may dissent from the Merger and upon complying with the requirements of 12 U.S.C. Section 215a and Sections 1115.9 and 1701.85 of the ORC will be entitled to receive the fair cash value of their shares instead of the merger consideration.

TABLE OF CONTENTS

A copy of the sections of the federal statute and the ORC pertaining to appraisal rights is attached as Annex B to this proxy statement/prospectus. You should read the statutes carefully and consult with your legal counsel if you intend to exercise these rights.

The Merger and the performance of the surviving bank are subject to a number of risks (See page 17)

There are a number of risks relating to the Merger and to the businesses of First Financial, First Bexley and the surviving bank following the Merger. See the “Risk Factors” beginning on page 17 of this proxy statement/prospectus for a discussion of these and other risks and see also the documents that Parent has filed with the SEC and which we have incorporated by reference into this proxy statement/prospectus.

First Bexley shareholder approval will be required to complete the Merger and approve the other proposals set forth in the notice (See page 21)

Under the federal law applicable to mergers of state banks into national banks, the Merger Agreement must be ratified and confirmed by the affirmative vote of First Bexley shareholders owning at least two-thirds of its common stock outstanding and entitled to vote at the special meeting. Approval of the proposal to adjourn the special meeting, if necessary, requires the affirmative vote of holders of at least a majority of the shares of First Bexley common stock having voting power, present in person or by proxy, if a quorum is present. In the absence of a quorum, the holders of a majority of the shares of First Bexley common stock present in person or by proxy may adjourn the special meeting. To satisfy the quorum requirements set forth in First Bexley’s regulations, shareholders holding at least a majority of the voting power of the outstanding shares of First Bexley common stock entitled to vote at the special meeting must be present in person or by proxy at the special meeting. Shareholders may vote their shares in person at the special meeting or by signing and returning the enclosed proxy form.

Certain shareholders of First Bexley have committed to vote their shares of First Bexley common stock in favor of the Merger. As of December 17, 2013, these shareholders owned 314,655 shares, constituting approximately 22.8% of the shares then outstanding. See “The Merger — Voting agreement” on page 42.

TABLE OF CONTENTS

Termination fees and expenses may be payable under some circumstances (See page 53)

If the Merger Agreement is terminated (i) by First Financial because the board of directors of First Bexley fails to make recommendation to First Bexley shareholders to adopt the Merger Agreement, or First Bexley has materially breached its covenant not to solicit alternative acquisition proposals, or (ii) by either party if First Bexley has received and would accept a superior alternative proposal from a third party, First Financial may be owed a termination fee from First Bexley equal to 5% of the sum of the total merger consideration and total cash consideration for cashing out First Bexley’s stock options, plus reimbursement for its out-of-pocket expenses incurred in connection with the proposed Merger.

If the Merger Agreement is terminated by either party because First Bexley shareholders fail to adopt the Merger Agreement, First Bexley will reimburse First Financial for its out-of-pocket expenses incurred in connection with the proposed Merger. See “Description of the Merger Agreement — Termination fee.”

Voting agreement (See page 42)

Certain shareholders of First Bexley have agreed to vote all of their shares of First Bexley common stock in favor of the Merger Agreement at the special meeting. The voting agreement covers approximately 24.0% of First Bexley’s outstanding shares of common stock as of December 17, 2013. The voting agreement will terminate if the Merger Agreement is terminated or the Merger becomes effective, whichever is earlier, in accordance with the terms of the Merger Agreement.

Accounting treatment of the Merger

The Merger will be accounted for as a purchase transaction in accordance with accounting principles generally accepted in the United States.

Certain differences in Parent shareholder rights and First Bexley shareholder rights (See page 57)

Parent is an Ohio corporation and a bank holding company registered under the Bank Holding Company Act of 1956, as amended, while First Bexley is an Ohio state-chartered commercial bank. Although the rights of the holders of Parent common shares and those of holders of First Bexley common shares are similar in

TABLE OF CONTENTS

many respects, there are some differences. These differences relate to differences between the provisions of Ohio law governing corporations and the provisions of Ohio law governing state-chartered commercial banks, as well as differences between provisions of Parent’s articles of incorporation and regulations and the First Bexley’s articles of incorporation and regulations. Certain of these differences are described in detail in the section entitled “Comparison of rights of Parent shareholders and First Bexley shareholders” beginning on page 57. After completion of the Merger, First Bexley shareholders who receive shares of Parent common stock in exchange for their shares of First Bexley common stock will become Parent shareholders and their rights will be governed by Parent’s articles of incorporation and regulations, in addition to laws and requirements that apply to public companies.

Parent shares will be listed on Nasdaq (See page 54)

The shares of Parent common stock to be issued pursuant to the Merger will be listed on Nasdaq under the symbol “FFBC.”

TABLE OF CONTENTS

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the caption “Special Notes Concerning Forward-Looking Statements” on page 20, you should consider the following risk factors carefully in deciding whether to vote for the adoption of the Merger Agreement. Additional risks and uncertainties not presently known to Parent and First Bexley or that are not currently believed to be important to you, if they materialize, also may adversely affect the Merger and Parent and First Bexley as a surviving bank.

In addition, Parent’s and First Bexley’s respective businesses are subject to numerous risks and uncertainties, including the risks and uncertainties described, in the case of Parent, in its Annual Report on Form 10-K for the year ended December 31, 2013, which are incorporated by reference into this proxy statement/prospectus.

Risks relating to the Merger

Because the market price of Parent common stock may fluctuate, you cannot be certain of the precise value of the stock portion of the merger consideration you may receive in the Merger.

At the time the Merger is completed, each issued and outstanding share of First Bexley common stock (other than shares owned by First Bexley, Parent, First Financial or any of their subsidiaries and shares of First Bexley common stock in respect of which appraisal rights have been properly exercised and perfected) will be converted into the right to receive consideration in the form of a combination of Parent common stock and cash, subject to certain adjustment. The exchange ratio for the Parent common stock with respect to the stock component of the merger consideration, as calculated in accordance with the formula set forth in the Merger Agreement, may fluctuate depending on the market price of Parent common stock during a reference period prior to the closing.

There will be a time lapse between each of the date on which First Bexley shareholders vote to approve the Merger and the Merger Agreement at the special meeting, the date on which the exchange ratio with respect to the stock component of the merger consideration is determined, and the date on which First Bexley shareholders entitled to receive shares of Parent common stock actually receive such shares. The market value of Parent common stock may fluctuate during these periods. Consequently, at the time First Bexley shareholders must decide whether to approve the Merger and the Merger Agreement, they will not know the actual market value of the shares of Parent common stock they will receive when the Merger is completed. The actual value of the shares of Parent common stock received by the First Bexley shareholders will depend on the market value of shares of Parent common stock on that date. This market value may be less than the value used to determine the exchange ratio, as that determination will be made with respect to a period occurring prior to the consummation of the Merger.

Because there is no public market for the First Bexley common stock, it is difficult to determine how the fair value of First Bexley common stock compares with the merger consideration.

The outstanding shares of First Bexley common stock are privately held and are not traded in any public market. This lack of a public market makes it difficult to determine the fair value of First Bexley. Because the merger consideration was determined based on negotiations between the parties, it may not be indicative of the fair value of the shares of First Bexley common stock.

The opinion that First Bexley has obtained from Keefe, Bruyette & Woods, Inc. has not been, and is not expected to be, updated to reflect any changes in circumstances that may have occurred since the signing of the Merger Agreement.

The opinion issued to the First Bexley board of directors by Keefe, Bruyette & Woods, Inc. (“KBW”), financial advisor to First Bexley, with respect to the fairness of the merger consideration to be received by First Bexley shareholders, from a financial point of view, speaks only as of December 17, 2013. Changes in the operations and prospects of Parent or First Bexley, general market and economic conditions and other factors which may be beyond the control of Parent and First Bexley, and on which the opinion was based, may have altered the value of Parent or First Bexley or the sale prices of shares of Parent common stock as of

TABLE OF CONTENTS

the date of this proxy statement/prospectus, or may alter such values and sale prices by the time the Merger is completed. KBW does not have any obligation to update, revise or reaffirm its opinion to reflect subsequent developments and has not done so. Because First Bexley does not currently anticipate asking KBW to update its opinion, the opinion will not address the fairness of the merger consideration from a financial point of view at the time the Merger is completed. The First Bexley board of directors’ recommendation that First Bexley shareholders vote “FOR” approval of the Merger Agreement, however, is made as of the date of this proxy statement/prospectus. See “The Merger — Opinion of Keefe, Bruyette & Woods, Inc.” and Appendix C to this proxy statement/prospectus.

First Financial may be unable to successfully integrate First Bexley’s operations and may not realize the anticipated benefits of acquiring First Bexley.

Parent, First Financial and First Bexley entered into the Merger Agreement with the expectation that First Financial would be able to successfully integrate First Bexley’s operations and that the Merger would result in various benefits, including, among other things, enhanced revenues and revenue synergies, an expanded market reach and operating efficiencies. Achieving the anticipated benefits of the Merger is subject to a number of uncertainties, including whether First Financial is able to integrate and operate First Bexley in an efficient and effective manner, and general competitive factors in the market place. The process of integrating operations could cause an interruption of, or loss of momentum in, the activities of one or more of the surviving bank’s businesses or the loss of key personnel. The diversion of management’s attention and any delays or difficulties encountered in connection with the Merger and the integration of the two banks’ operations could have an adverse effect on the business, financial condition, operating results and prospects of the surviving bank after the Merger. Failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy and could have an adverse effect on the surviving bank’s business, financial condition, operating results and prospects.

Among the factors considered by the boards of directors of Parent and First Bexley in connection with their respective approvals of the Merger Agreement were the benefits that could result from the Merger. We cannot give any assurance that these benefits will be realized within the time periods contemplated or even that they will be realized at all.

First Bexley will be subject to business uncertainties while the Merger is pending, which could adversely affect its business.

Uncertainty about the effect of the Merger on employees and customers may have an adverse effect on First Bexley, and, consequently, the surviving bank. Although First Bexley intends to take steps to reduce any adverse effects, these uncertainties may impair First Bexley’s ability to attract, retain and motivate key personnel until the Merger is consummated and for a period of time thereafter, and could cause customers and others that deal with First Bexley to seek to change their existing business relationships with First Bexley. Employee retention at First Bexley may be particularly challenging during the pendency of the Merger, as employees may experience uncertainty about their roles with the surviving bank following the Merger.

TABLE OF CONTENTS

Some of the directors and executive officers of First Bexley have interests and arrangements that could have affected their respective decision to support or approve the Merger.

The interests of some of the directors and executive officers of First Bexley in the Merger are different from, and may be in addition to, those of First Bexley shareholders generally and could have affected their decision to support or approve the Merger. These interests include:

In addition, certain directors of First Bexley who own shares of First Bexley common stock and certain other shareholders of First Bexley have entered into a voting agreement that requires them to vote all of their shares of First Bexley common stock in favor of the Merger Agreement at the special meeting. The voting agreement covers approximately 24.0% of First Bexley’s outstanding shares of common stock as of December 17, 2013. As a result, these directors of First Bexley may be more likely to recommend to First Bexley’s shareholders the adoption of the Merger Agreement than if they did not have these interests.

Risks relating to the businesses of Parent and the surviving bank

First Bexley’s shareholders will not control Parent’s future operations.

Currently, First Bexley’s shareholders own 100% of First Bexley and have the power to approve or reject any matters requiring shareholder approval under Ohio law and First Bexley’s articles of incorporation and code of regulations. After the Merger, absent any adjustment made to the ratio of stock component in the merger consideration, First Bexley shareholders are expected to become owners of less than 5% of the outstanding shares of Parent common stock. Even if all former First Bexley shareholders voted together on all matters presented to Parent’s shareholders, from time to time, the former First Bexley shareholders most likely would not have a significant impact on the approval or rejection of future Parent proposals submitted to a shareholder vote.

TABLE OF CONTENTS

SPECIAL NOTES CONCERNING FORWARD-LOOKING STATEMENTS

This document contains, and the documents into which it may be incorporated by reference may contain, forward-looking statements within the meaning of federal securities laws. Examples of forward-looking statements include, but are not limited to, projections of revenues, income or loss, earnings or loss per share, the payment or non-payment of dividends, capital structure and other financial items, statements of plans and objectives of First Financial or its management or board of directors and statements of future economic performances and statements of assumptions underlying such statements. Words such as ''believes,'' ''anticipates,'' “likely,” “expected,” ''intends,'' and other similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. Forward-looking statements and information are not historical facts, are premised on many factors and assumptions, and represent only management’s expectations, estimates and projections regarding future events. Similarly, these statements are not guarantees of future performance and involve certain risks and uncertainties that are difficult to predict, which may include, but are not limited to, those listed below and the Risk Factors discussed under Item 1A of Parent’s 2013 Annual Report on Form 10-K and in any of Parent’s subsequent SEC filings. Parent intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and is including this statement for purposes of invoking these safe harbor provisions. Management's analysis contains forward-looking statements that are provided to assist in the understanding of anticipated future financial performance. However, such performance involves risks and uncertainties that may cause actual results to differ materially. Factors that could cause actual results to differ from those discussed in the forward-looking statements include, but are not limited to:

TABLE OF CONTENTS

Therefore, there can be no assurances that future actual results will correspond to these forward-looking statements. The reader is cautioned not to place undue reliance on any forward-looking statement made by Parent. Forward-looking statements speak only as of the date they are made, and Parent undertakes no obligation to update any forward-looking statement to reflect the impact of circumstances or events that arise after the date the forward-looking statement was made. Persons are advised, however, to consult further disclosures management makes on related subjects in its reports filed with the SEC and in its press releases.

INFORMATION ABOUT THE SPECIAL MEETING OF FIRST BEXLEY SHAREHOLDERS

First Bexley’s board of directors is using this proxy statement/prospectus to solicit proxies from the holders of First Bexley common stock for use at the special meeting of First Bexley’s shareholders.

Date, time and place of the special meeting

The special meeting will be held at the offices of First Bexley, located at 2680 East Main Street, Bexley, Ohio 43209 on           , 2014 at    , local time.

Purpose of the special meeting

At the special meeting, First Bexley board of directors will ask you to vote upon the following:

TABLE OF CONTENTS

Record date and voting rights for the special meeting

First Bexley has set the close of business on           , 2014, as the record date for determining the holders of its common stock entitled to notice of and to vote at the special meeting. Only First Bexley shareholders at the close of business on the record date are entitled to notice of and to vote at the special meeting. As of the record date, there were       shares of First Bexley common stock outstanding and entitled to vote at the special meeting.

Quorum

The presence in person or by proxy of at least a majority of First Bexley’s shares issued and outstanding and entitled to vote at the special meeting is required for a quorum to be present at the special meeting. Abstentions and broker non-votes will count toward the establishment of a quorum.

Vote required

Under the federal law applicable to mergers of state banks into national banks, the Merger Agreement must be ratified and confirmed by the affirmative vote of First Bexley shareholders owning at least two-thirds of its common stock outstanding and entitled to vote at the special meeting. Approval of the proposal to adjourn the special meeting to permit further solicitation in the event that an insufficient number of shares are present in person or by proxy to adopt the Merger Agreement and the transactions it contemplates requires the affirmative vote of at least a majority of the shares of First Bexley common stock having voting power, present in person or by proxy at the special meeting, if a quorum is present. In the absence of a quorum, holders of a majority of the shares of First Bexley common stock present in person or by proxy at the special meeting may adjourn the special meeting.

The failure of a First Bexley shareholder to vote or to instruct his or her broker, bank or nominee to vote if his or her shares are held in “street name”, which we refer to as a broker non-vote, will have the same effect as voting against the proposals to adopt the Merger Agreement and the meeting adjournment proposal. For purposes of the shareholder vote, an abstention, which occurs when a shareholder attends a meeting, either in person or by proxy, but abstains from voting, will have the same effect as voting against the proposals to adopt the Merger Agreement and to adjourn the special meeting.

Shares held by First Bexley directors; voting agreements

Certain First Bexley directors who own shares of First Bexley common stock and certain other shareholders of First Bexley, whose aggregate ownership represents approximately 24.0% of First Bexley’s outstanding shares of First Bexley common stock as of December 17, 2013, have committed to vote their shares in favor of the Merger. Parent does not own any shares of First Bexley common stock. See “The Merger — Voting agreement” on page 42 for a description of the provisions of the voting agreement.

How to vote

You may vote in person at the special meeting or by proxy. To ensure your representation at the special meeting, we recommend you vote by proxy even if you plan to attend the special meeting. You can change your vote at the special meeting if you so desire.

Voting instructions are included on your proxy form, which should be returned in the enclosed prepaid envelope. If you properly complete and timely submit your proxy, your shares will be voted as you have directed. You may vote for, against, or abstain with respect to the approval of the Merger and the other proposals. If you are the record holder of your shares and submit your proxy without specifying a voting instruction, your shares will be voted as the First Bexley board of directors recommends and will be voted “FOR” adoption of the Merger Agreement and “FOR” the adjournment of the special meeting to permit further solicitation in the event that an insufficient number of shares are present in person or by proxy to adopt the Merger Agreement and the transactions it contemplates.

Revocability of proxies

You may revoke your proxy at any time before it is voted by:

TABLE OF CONTENTS

Attendance at the special meeting will not, in and of itself, constitute a revocation of a proxy. All written notices of revocation and other communication with respect to the revocation of proxies should be addressed to: The First Bexley Bank, 2680 E. Main St. Columbus, Ohio 43209, Attention: David Mallet, President and Chief Executive Officer.

Proxy solicitation

In addition to this mailing, proxies may be solicited by directors, officers or employees of First Bexley in person or by telephone or electronic transmission. None of such directors, officers or employees will be directly compensated for such services. First Bexley will pay the costs associated with the solicitation of proxies for the special meeting.

Other business; adjournments

First Bexley is not currently aware of any other business to be acted upon at the First Bexley special meeting. If, however, other matters are properly brought before the special meeting, or any adjournment or postponement thereof, your proxies include discretionary authority on the part of the individuals appointed to vote your shares to act on those matters according to their best judgment.

Adjournments may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment may be made from time to time by the affirmative vote of the holders of a majority of the shares of First Bexley common stock present in person or by proxy at the special meeting, whether or not a quorum is present, without further notice other than by announcement at the special meeting.

TABLE OF CONTENTS

THE MERGER

This section of the proxy statement/prospectus describes material aspects of the Merger. While Parent and First Bexley believe that the description covers the material terms of the Merger and the related transactions, this summary may not contain all of the information that is important to you. You should carefully read this entire proxy statement/prospectus, the attached Annexes, and the other documents to which this proxy statement/prospectus refers for a more complete understanding of the Merger. The Merger Agreement attached hereto as Annex A, not this summary, is the legal document which governs the Merger.

General

The First Bexley board of directors is using this proxy statement/prospectus to solicit proxies from the holders of First Bexley common stock for use at the First Bexley special meeting, at which First Bexley shareholders will be asked to vote on the adoption of the Merger Agreement and thereby approve the Merger. When the Merger is consummated, First Bexley will merge with and into First Financial and will cease to exist. First Financial will survive the Merger and remain a wholly owned subsidiary of Parent. At the effective time of the Merger, holders of First Bexley common stock will exchange their shares for a combination of cash and shares of Parent common stock, subject to certain adjustment depending upon changes in the market price of Parent’s common stock. Each share of First Bexley common stock will be exchanged for the per share merger consideration, the stock component of which cannot be determined until the third business day prior to the effective time of the Merger. See “Description of the Merger Agreement — Consideration to be received in the Merger” for a detailed description of the method for determining the per share merger consideration.

Only whole shares of Parent common stock will be issued in the Merger. As a result, cash will be paid instead of any fractional shares based on the Parent Share Average Closing Price of Parent’s common stock, which will be calculated by reference to the twenty trading days ending on the third business day prior to the effective time of the Merger. Shares of First Bexley common stock held by First Bexley shareholders who elect to exercise their appraisal rights will not be converted into merger consideration.

First Bexley’s proposals

At the First Bexley special meeting, holders of shares of First Bexley common stock will be asked to vote on the adoption of the Merger Agreement and thereby approve the Merger. The Merger will not be completed unless First Bexley’s shareholders adopt the Merger Agreement and thereby approve the Merger.

Background of the Merger

First Bexley was organized and commenced operations in 2006. Between 2006 and 2013, First Bexley grew organically from $32.2 million in assets at the end of 2006 to $309.0 million in assets as of December 31, 2013. Given the challenges in the external banking environment, and the ability of a one branch bank to continue to have access to adequate liquidity to fund future growth, First Bexley’s board of directors and senior management in late 2011 began reviewing and considering strategic options available to it in order to enhance First Bexley’s performance and prospects. These options included First Bexley acquiring other banks and branches in its market area, de novo branching strategies, as well as evaluating the potential sale of First Bexley to a strategic merger partner. In 2012, First Bexley decided to move forward with formally exploring the strategic alternative of selling First Bexley and retained Keefe, Bruyette & Woods, Inc. (“KBW”) as its financial advisor to assist First Bexley in exploring a potential sale transaction with a strategic merger partner. First Bexley tasked KBW with contacting potential acquirors and assessing whether other parties might be willing to entertain a strategic merger with First Bexley.

Following its own due diligence of First Bexley and the preparation of a bank-approved list of potential strategic merger partners, KBW began marketing First Bexley in 2012 to a pool of 26 potential acquirers. As a result of these marketing efforts, in March and April 2012, 11 potential strategic partners executed confidentiality agreements and were provided access to confidential business and financial information about First Bexley in order to evaluate a potential transaction. Between April 19 and 23, 2012, three of these parties submitted written expressions of interest to First Bexley of their intention to pursue a potential strategic merger. In June 2012, a potential acquirer submitted a final indication of interest and subsequent discussions to consummate the Merger ensued. In July 2012 the parties were unable to come to agreement on certain terms of related to the definitive agreement and, as a result, the negotiations were terminated prior to the signing of a definitive agreement.

In early 2013, following a review of strategic alternatives, the First Bexley board of directors instructed KBW that it would entertain discussions with select strategic partners. In August 2013, KBW introduced First Bexley to First Financial. In September and October 2013, First Bexley and First Financial executed a non-disclosure agreement and shared preliminary due diligence information. On October 17, 2013, First Financial submitted an indication of interest with an offer price per share range of $29.50 to $30.50 per share or $40.7 to $42.1 million with 25% of the consideration to be paid in cash and 75% in Parent common stock. In addition, outstanding First Bexley options would be cashed out at the in-the-money value of approximately $2.3 to $2.4 million, bringing the fully diluted transaction value between $43.0 to $44.5 million. On October 24, 2013, First Bexley and First Financial entered into a Letter of Intent for the proposed Merger.

TABLE OF CONTENTS

In October and November 2013, Parent and First Financial performed final due diligence on First Bexley and First Bexley performed reverse due diligence on Parent and First Financial. The parties concurrently worked to finalize the drafting of a definitive merger agreement during this period.

On November 21, 2013, Squire Sanders (US) LLP, counsel to Parent and First Financial, delivered the initial draft of the Merger Agreement to First Bexley and Patton Boggs LLP, counsel to First Bexley. On November 29, 2013, Patton Boggs LLP provided First Bexley’s comments to the initial draft of the Merger Agreement to Parent and First Financial’s legal counsel. During the months of November and December of 2013, the parties continued to negotiate the terms of the Merger Agreement to resolve the remaining legal and business matters between them, which included the parties agreeing to an increase in the percentage of stock consideration that First Bexley shareholders would receive for each share of First Bexley common stock exchanged for the per share merger consideration from 75% to 80%. On December 12, 2013, the Parent board of directors held a special meeting at which Parent’s management and Squire Sanders (US) LLP were represented. Management of Parent, with the assistance of its legal counsel, reviewed the terms of the Merger Agreement. Based upon the Parent’s board’s review and discussion of the Merger Agreement, the Parent board unanimously approved the Merger Agreement.

On December 17, 2013, First Bexley’s board of directors held a special meeting and discussed and considered the terms and conditions of the Merger Agreement. Members of First Bexley’s senior management, KBW and Patton Boggs LLP participated in First Bexley’s board meeting, and reviewed the terms and conditions of the Merger Agreement and the structure of the Merger with the board. KBW presented its financial analysis of the Merger and rendered its oral opinion, which was subsequently confirmed in writing, that as of such date, the Merger was fair, from a financial point of view, to the common shareholders of First Bexley. KBW provided the board with the results of its reverse due diligence of Parent and First Financial and the contents of the reverse diligence memorandum. Following an extensive discussion by First Bexley’s board of directors and based upon its review and discussion of the Merger Agreement with KBW and Patton Boggs LLP, the reverse due diligence conducted on Parent and First Financial and the presentation and fairness opinion from KBW, First Bexley’s board of directors unanimously approved the Merger Agreement and authorized the President and Chief Executive Officer to execute the Merger Agreement on behalf of First Bexley.

The Merger Agreement was entered into by the appropriate officers of Parent, First Financial and First Bexley after the closing of the financial markets on December 17, 2013. First Bexley and Parent issued a joint press release on December 18, 2013 announcing the execution of the Merger Agreement.

Recommendation of First Bexley’s Board and Its Reasons for the Merger

After careful consideration at its meeting, First Bexley’s board of directors unanimously approved the Merger and the Merger Agreement and unanimously recommends that First Bexley’s shareholders vote FOR approval of the Merger Agreement. In approving the Merger Agreement, First Bexley’s board of directors consulted with KBW with respect to the financial aspects and fairness of the merger consideration, from a financial point of view, to the holders of shares of First Bexley common stock and with its outside legal counsel as to its legal duties and the terms of the Merger Agreement. The board believes that combining with Parent and First Financial will allow First Bexley’s shareholders to participate in a stronger and more diversified organization that will provide significant benefits to First Bexley’s shareholders and customers alike.

Opinion of First Bexley’s Financial Advisor

First Bexley engaged Keefe, Bruyette & Woods, Inc. (“KBW”) to render an opinion to the First Bexley board of directors as to the fairness, from a financial point of view, to the shareholders of First Bexley of the merger consideration in the proposed merger of First Bexley with and into First Financial, a wholly owned subsidiary of Parent. First Bexley selected KBW because KBW is a nationally recognized investment banking firm with substantial experience in transactions similar to the Merger and is familiar with First Bexley and its business. As part of its investment banking business, KBW is continually engaged in the valuation of financial businesses and their securities in connection with mergers and acquisitions.

As part of its engagement, representatives of KBW attended the meeting of the First Bexley board of directors held on December 17, 2013, at which the First Bexley board of directors 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 set forth in such opinion, the merger consideration in the proposed merger was fair, from a financial point of view, to the shareholders of First Bexley. For purposes of KBW’s opinion and with the consent of the First Bexley board of directors, the merger consideration was assumed to be equal to $30.50 per share of First Bexley common stock. The First Bexley board of directors 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 document 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’s opinion speaks only as of the date of the opinion. The opinion was for the information of, and was directed to, the First Bexley board of directors (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 shareholders of First Bexley. It did not address the underlying business decision to proceed with the Merger or constitute a recommendation to the First Bexley board of directors in connection with the Merger, and it does not

TABLE OF CONTENTS

constitute a recommendation to any First Bexley shareholder as to how such shareholder should vote at the First Bexley special meeting on the Merger or on any related matter.

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 rendering its opinion, KBW reviewed, 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 First Bexley, First Financial and Parent 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 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 it 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 First Bexley as to the reasonableness and achievability of the financial and operating forecasts and projections of First Bexley (and the assumptions and bases therefor) that were prepared and provided by such management and KBW assumed, at the direction of First Bexley, that such forecasts and projections were reasonably prepared on a

TABLE OF CONTENTS

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. KBW further relied upon management of First Financial and Parent as to the reasonableness and achievability of the estimates regarding certain pro forma financial effects of the Merger on First Financial and Parent prepared and provided by management of First Financial and Parent (and the assumptions and bases therefor), and KBW assumed that such estimates were reasonably prepared on a basis reflecting the best currently available estimates and judgments of such management and that such estimates will be realized in the amounts and in the time periods currently estimated by such management.

It is understood that such forecasts, projections and estimates provided to KBW by the respective managements of First Bexley, First Financial and Parent, as the case may be, were not prepared with the expectation of public disclosure, that all such projected financial information is 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. KBW assumed, based on discussions with the respective managements of First Bexley, First Financial and Parent, that such forecasts, projections and estimates as well as publicly available consensus “street estimates” of Parent referred to above, 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 this information without independent verification or analysis and therefore did not in any respect assume any responsibility or liability for the accuracy or completeness thereof. KBW further assumed, with the consent of the First Bexley board of directors, that the actual value of the consideration to be received by the holders of First Bexley common stock in the Merger will not differ from that assumed by KBW in any respect that would be material to KBW’s analysis or opinion.

KBW assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either First Bexley or Parent 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 it assumed, without independent verification and with First Bexley’s consent that the aggregate allowances for loan and lease losses for First Bexley and Parent 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 First Bexley or Parent, 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 First Bexley or Parent 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.

For purposes of rending its opinion, KBW assumed that, in all respects material to its analysis:

TABLE OF CONTENTS

KBW further assumed that the Merger would 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. KBW further assumed that First Bexley 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 First Bexley, First Financial, Parent, the Merger 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 December 17, 2013, of the merger consideration in the Merger to the shareholders of First Bexley. KBW expressed no view or opinion as to any terms or other aspects of the Merger, including without limitation, the form or structure of the Merger, any consequences of the Merger to First Bexley, its shareholders, creditors or otherwise, or any terms, aspects or implications of any voting, support, shareholder or other agreements, arrangements or understandings contemplated or entered into in connection with the Merger or otherwise. 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. It is understood that subsequent developments may affect the conclusion reached in KBW’s opinion and that KBW does not have an obligation to update, revise or reaffirm its opinion. KBW’s opinion did not address, and it 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, First Bexley, First Financial and Parent. 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 First Bexley board of directors in

TABLE OF CONTENTS

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 First Bexley board of directors with respect to the fairness of the Merger consideration. The type and amount of consideration payable in the Merger were determined through negotiation between First Bexley and First Financial and the decision to enter into the Merger Agreement was solely that of First Bexley’s board.

The following is a summary of the material financial analyses presented by KBW to the First Bexley board of directors on December 17, 2013, in connection with its fairness opinion. The summary is not a complete description of the financial analyses underlying the KBW opinion or the presentation made by KBW to the First Bexley board of directors, 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 the most 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 the financial analyses described below, KBW utilized an implied value of the merger consideration of $30.50 per share of First Bexley common stock (consisting of (i) $6.10 in cash and (ii) an ascribed value of $24.40 to the shares of Parent common stock to be issued in the Merger for each share of First Bexley).

No company or transaction used as a comparison in the above analysis is identical to Parent, First Bexley 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.

Discounted Cash Flow Analysis.  KBW performed a discounted cash flow analysis to estimate a range for the implied equity value of First Bexley. In this analysis, KBW assumed discount rates ranging from 14.0% to 16.0% to derive (i) the present value of the estimated free cash flows that First Bexley could

TABLE OF CONTENTS

generate over a five year period, as a standalone company, and (ii) the present value of First Bexley’s terminal value at the end of year five. Terminal values for First Bexley were calculated based on a range of 12.0x to 14.0x estimated 2019 net income. In performing this analysis, KBW used estimates for First Bexley provided by First Bexley’s management. KBW assumed that First Bexley would maintain a tangible common equity/tangible asset ratio of 9.00% and would retain sufficient earnings to maintain that level.

Based on these assumptions, KBW derived a range of implied aggregate value per share of First Bexley of $25.79 per common share to $32.15 per common share.

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 First Bexley.

Forecasted Pro Forma Financial Analysis.  KBW analyzed the estimated financial impact of the Merger on Parent’s 2014 estimated earnings per share and Parent’s tangible book value per share as of June 30, 2014. Based on its analysis, KBW determined that the Merger would be accretive to Parent’s estimated GAAP earnings per share in 2014, assuming a full year impact, but dilutive to Parent’s tangible book value per share.

Furthermore, the analysis indicated that Parent’s Leverage Ratio, Tier 1 Risk-Based Capital Ratio and Total Risk Based Capital Ratio would all remain “well capitalized” by regulatory standards. For all of the above analysis, the actual results achieved by Parent following the Merger may vary from the projected results, and the variations may be material.

Miscellaneous.  KBW acted as financial advisor to First Bexley 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. In the ordinary course of its business as a broker-dealer, KBW may, from time to time, purchase securities from, or sell securities to, First Bexley, First Financial and Parent. 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 First Bexley and Parent for its own account and for the accounts of its customers. To the extent KBW held any such positions as of the date of its opinion, it was disclosed to the First Bexley board of directors.

Pursuant to the KBW engagement agreement, First Bexley agreed to pay KBW a cash fee of $200,000 concurrently with the rendering of its opinion and a cash fee, upon closing of the Merger, equal to a percentage of the actual aggregate merger consideration, as follows: (i) 1.5% of the aggregate consideration up to $39.0 million, (ii) 5.0% of the aggregate consideration between $39.0 and $40.0 million and (iii) 10.0% of the aggregate consideration in excess of $40.0 million. In addition, First Bexley 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, including liabilities under the federal securities laws. During the two years preceding the date of its opinion, KBW provided investment banking and financial advisory services to First Bexley and received compensation for such services. KBW had been previously engaged as a financial advisor by First Bexley in January 2012 in order to determine potential strategic alternatives. During the two years preceding the date of its opinion KBW did not provide investment banking and financial advisory services to First Financial or Parent. KBW may in the future provide investment banking and financial advisory services to First Bexley, First Financial, or Parent and receive compensation for such services.

Material U.S. federal income tax consequences of the Merger

The following summary describes the material U.S. federal income tax consequences of the Merger to U.S. holders (as defined below) of First Bexley common stock. The summary is based upon the Code, applicable Treasury Regulations, judicial decisions and administrative rulings and practice, all as in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. This summary does not address any tax consequences of the Merger under state, local or foreign laws, or any federal laws other than those pertaining to income tax.

TABLE OF CONTENTS

For purposes of this discussion, the term “U.S. holder” means a beneficial owner that is: an individual citizen or resident of the United States; a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or any of its political subdivisions; a trust that (1) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or an estate that is subject to U.S. federal income taxation on its income regardless of its source.

This discussion addresses only those U.S. holders of First Bexley common stock that hold their First Bexley common stock as a capital asset within the meaning of Section 1221 of the Code and does not address all the U.S. federal income tax consequences that may be relevant to particular holders of First Bexley common stock in light of their individual circumstances or to holders of First Bexley common stock that are subject to special rules, such as:

If a partnership (or other entity that is taxed as a partnership for federal income tax purposes) holds First Bexley common stock, the tax treatment of a partner in that partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships and partners in partnerships should consult their own tax advisors about the tax consequences of the Merger to them.

FIRST BEXLEY SHAREHOLDERS ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS AS TO THE TAX CONSEQUENCES OF THE MERGER IN THEIR PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL (INCLUDING THE ALTERNATIVE MINIMUM TAX), STATE, LOCAL OR FOREIGN AND OTHER TAX LAWS AND OF CHANGES IN THOSE LAWS.

Tax Consequences of the Merger.  As a condition to the completion of the Merger, Patton Boggs LLP must have delivered an opinion to First Bexley and the First Bexley shareholders, dated the Closing Date of the Merger, to the effect that the Merger will be treated as a tax-free reorganization for U.S. federal income tax purposes within the meaning of Section 368(a) of the Code and that each of First Bexley, First Financial and Parent will be a party to such reorganization. The opinion will assume that the Merger will be completed according to the terms of the Merger Agreement and that the parties will report the transaction in a manner consistent with the opinion. The opinion will rely on the facts as stated in the Merger agreement, the Registration Statement on Form S-4 (of which this proxy statement/prospectus is a part) and certain other documents. In rendering the tax opinion, counsel will rely on representations of First Bexley, First Financial

TABLE OF CONTENTS

and Parent, to be updated as of the effective time of the Merger (and will assume that any such representation that is qualified by belief, knowledge or materiality is true, correct and complete without such qualification). If any such assumption or representation is or becomes inaccurate, the U.S. federal income tax consequences of the Merger could be adversely affected. The opinion will be based on statutory, regulatory and judicial authority existing as of the date of the opinion, any of which may be changed at any time with retroactive effect.

An opinion of counsel represents counsel's best legal judgment but is not binding on the IRS or on any court. None of First Bexley, First Financial and Parent intends to request any ruling from the IRS as to the U.S. federal income tax consequences of the Merger. Consequently, no assurance can be given that the IRS will not assert, or that a court will not sustain, a position contrary to any of the tax consequences set forth below or any of the tax consequences described in the tax opinion.

Based on representations contained in representation letters of officers of First Bexley, First Financial and Parent, all of which must continue to be true and accurate in all material respects as of the effective time of the Merger, and subject to the other matters set forth above, it is the opinion of Patton Boggs, LLP, that the Merger will qualify as a tax-free reorganization within the meaning of Section 368(a) of the Code and that each of First Bexley, First Financial and Parent will be a party to such reorganization. Based upon the foregoing, the material U.S. federal income tax consequences of the Merger will be as described below.

If a U.S. holder of First Bexley common stock acquired different blocks of First Bexley common stock at different times or at different prices, any gain or loss will generally be determined separately with respect to each block of First Bexley common stock, and the cash and shares of Parent common stock received will be allocated pro rata to each such block of stock. A loss realized on the exchange of one block of shares cannot be used to offset a gain realized on the exchange of another block of shares, but a U.S. holder will be able to reduce its capital gains by capital losses in determining its income tax liability. Each U.S. holder should consult its own tax advisor with regard to identifying the bases or holding periods of the particular shares of Parent common stock received in the Merger.

Taxation of Gain.  Except as described under “— Potential Recharacterization of Gain as a Dividend” below, gain that a U.S. holder of First Bexley common stock recognizes in connection with the Merger generally will constitute capital gain and will constitute long-term capital gain if such U.S. holder has held (or is treated as having held) its First Bexley common stock for more than one year as of the date of the Merger.

TABLE OF CONTENTS

For a non-corporate U.S. holder of First Bexley common stock, the maximum U.S. federal income tax rate on long-term capital gains generally is 20%.

Potential Recharacterization of Gain as a Dividend.  All or part of the gain that a particular U.S. holder of First Bexley common stock recognizes could be treated as having the effect of the distribution of a dividend to such U.S. holder under the tests set forth in Section 302 of the Code. These tests are complex and dependent upon the specific factual circumstances particular to each U.S. holder. As such, it is not possible to provide an opinion as to the potential impact of these tests. If the results of these tests is to treat the receipt of cash as having the effect of the distribution of a dividend, then this would mean that all or a portion of the recognized gain would be treated as ordinary dividend income, rather than capital gain. Consequently, each U.S. holder that may be subject to those rules should consult its tax advisor as to the application of these rules to the particular facts relevant to such U.S. holder.

Cash Received Instead of a Fractional Share of Parent Common Stock.  A U.S. holder of First Bexley common stock who receives cash in lieu of a fractional share of Parent common stock will be treated as having received the fractional share pursuant to the Merger and then as having exchanged the fractional share for cash in a redemption by Parent. As a result, such U.S. holder of First Bexley common stock will generally recognize gain or loss equal to the difference between the amount of cash received and the basis in his or her fractional share interest as set forth above. The gain or loss recognized by the U.S. holders described in this paragraph will generally be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the Merger, the U.S. holder’s holding period for the relevant shares is greater than one year. The deductibility of capital losses is subject to limitations.

Medicare Tax on Unearned Income.  A U.S. holder that is an individual is subject to a 3.8% tax on the lesser of (i) his or her “net investment income” for the relevant taxable year or (ii) the excess of his or her modified gross income for the taxable year over a certain threshold (between $125,000 and $250,000 depending on the individual’s U.S. federal income tax filing status). A similar regime applies to estates and trusts. Net investment income generally would include any capital gain recognized in connection with the Merger (including any gain treated as dividend).

Backup Withholding and Information Reporting.  Payments of cash to a U.S. holder of First Bexley common stock pursuant to the Merger may, under certain circumstances, be subject to information reporting and backup withholding unless the holder provides proof of an applicable exemption or, in the case of backup withholding, furnishes its taxpayer identification number and otherwise complies with all applicable requirements of the backup withholding rules. Any amounts withheld from payments to a U.S. holder under the backup withholding rules are not additional tax and generally will be allowed as a refund or credit against the U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

A U.S. holder of First Bexley common stock who receives Parent common stock as a result of the Merger will be required to retain records pertaining to the Merger. Each U.S. holder of First Bexley common stock who is required to file a U.S. federal income tax return and who is a “significant holder” that receives Parent common stock in the Merger will be required to file a statement with such U.S. federal income tax return in accordance with Treasury Regulations Section 1.368-3 setting forth such holder’s basis in the First Bexley common stock surrendered and the fair market value of the Parent common stock and cash received in the Merger. A “significant holder” is a holder of First Bexley common stock who, immediately before the Merger, owned at least 5% (by vote or value) of the outstanding stock of First Bexley or securities of First Bexley with a tax basis of $1 million or more.

This discussion does not address tax consequences that may vary with, or are contingent upon, individual circumstances. Moreover, it does not address any non-income tax or any foreign, state or local tax consequences of the Merger. Tax matters are very complicated, and the tax consequences of the Merger to you will depend upon the facts of your particular situation. Accordingly, we strongly urge you to consult with a tax advisor to determine the particular federal, state, local or foreign income or other tax consequences to you of the Merger.

TABLE OF CONTENTS

Regulatory approvals

The Merger cannot proceed without obtaining all requisite regulatory approvals. Parent, First Financial and First Bexley have agreed to take all appropriate actions necessary to obtain the required approvals.

The Merger of First Financial and First Bexley is subject to prior approval of the OCC. First Financial submitted an application with the OCC on January 27, 2014 seeking the necessary approval.

The Merger may not be consummated until 30 days, which may be shortened to 15 days by the OCC, after receipt of OCC approval, during which time the United States Department of Justice may challenge the Merger on antitrust grounds. The commencement of an antitrust action would stay the effectiveness of the OCC’s approval, unless a court specifically orders otherwise.

Interests of certain persons in the Merger

General.  Some members of the board of directors and executive officers of First Bexley may have interests in the Merger that are different from, or are in addition to, the interests of First Bexley shareholders generally. These interests include, among others, proposed employee benefits for those who become employees of First Financial after the Merger, the appointment of one director designated by First Bexley to serve on the board of directors of Parent, the appointment of certain First Bexley director or directors to the Columbus advisory board of Parent, lump sum cash payments in exchange for the cancellation of outstanding First Bexley stock options, and indemnification and insurance coverage for First Bexley’s directors and officers, as described below.

The First Bexley board of directors was aware of these interests and considered them, among other matters, in approving the Merger Agreement and determining to recommend to First Bexley shareholders to vote for adoption of the Merger Agreement. As of February 6, 2014, First Bexley’s directors and executive officers beneficially owned, in the aggregate, 340,781 shares of First Bexley’s common stock, representing approximately 22.83% of First Bexley’s outstanding shares of common stock. For more information, see the section entitled “Security Ownership of Certain Beneficial Owners and Management of First Bexley.”

Employee Benefits.  As described under the caption “Description of the Merger Agreement — Employee benefit matters,” the Merger Agreement generally provides that each employee who, in Parent and First Financial’s sole discretion, continues employment with the surviving bank will be provided wages or salaries and employee benefit (excluding equity plans) that in the aggregate are substantially comparable to what he or she receives at First Bexley immediately prior to the closing date. Each employee of First Bexley who does not continue employment with the surviving bank will be provided with severance benefits under First Financial’s existing severance practices or pursuant to the terms of any applicable employment agreement with First Bexley in existence as of the date of the Merger Agreement, credited with his or her years of service with First Bexley.

Appointments in Connection with the Merger.  As described above under the caption “Description of the Merger Agreement — Management of Parent, First Financial and First Bexley after the Merger,” at or promptly following the effective time of the Merger, Parent will (i) appoint one qualified, independent director designated by First Bexley to serve on Parent’s board of directors (subject to the approval of Parent’s Corporate Governance and Nominating Committee), and (ii) create a Columbus advisory board and appoint certain director or directors from the current board of directors of First Bexley, as agreed among Parent, First Financial and First Bexley, to serve on the Columbus advisory board.

Cash-Out of Stock Options.  As described above under the caption “Description of the Merger Agreement — Cash-Out of Stock Options,” at the effective time, all rights with respect to First Bexley common stock pursuant to stock options granted by First Bexley will be converted into the rights to receive cash only. The Merger Agreement requires First Bexley to enter into option cash-out agreements with all its stock option holders to ensure that, immediately prior to the effective time, each First Bexley stock option, whether or not then exercisable, be cancelled at the effective time and only entitle the holders to receive a cash amount.

TABLE OF CONTENTS

Continued Director and Officer Liability Coverage.  Pursuant to the terms of the Merger Agreement, First Financial will, for six years after the effective time, maintain in effect the current directors’ and officers’ liability insurance policies maintained by First Bexley with respect to matters occurring prior to the effective time or, alternatively, substitute policies of at least the same coverage and amounts. However, First Financial is not required to expend more than an amount per year equal to 200% of current annual premiums paid by First Bexley for such insurance.

In addition, First Financial and Parent have agreed to, for six years after the effective time of the Merger, (i) indemnify and hold harmless the current and former directors, officers and employees of First Bexley and its subsidiaries for all actions taken by them in such capacities prior to the effective time and (ii) assume all obligations of First Bexley and its subsidiaries to such directors, officers and employees in respect of indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the effective time as provided in their organizational documents.

Voting agreement

Certain directors of First Bexley who own shares of First Bexley common stock and certain other shareholders of First Bexley have entered into a voting agreement with First Financial. Under this agreement, these shareholders have each agreed, among other things, to vote their respective shares of First Bexley common stock: (i) in favor of the adoption of the Merger Agreement; (ii) against approval of any proposal made in opposition to, or in competition with, the Merger; and (iii) against certain other actions that would impede, interfere with, delay, postpone, discourage or adversely affect the Merger.

The shares subject to the voting agreement represent approximately 24.0% of First Bexley’s outstanding shares of common stock as of December 17, 2013. The voting agreement will terminate if the Merger Agreement is terminated or the Merger becomes effective, whichever is earlier, in accordance with the terms of the Merger Agreement.

Restrictions on resale of Parent common stock

The shares of Parent common stock to be issued in connection with the Merger will be registered under the Securities Act of 1933, as amended (the “Securities Act”), and will be freely transferable, except for shares issued to any shareholder who may be deemed to be an “affiliate” of Parent for purposes of Rule 144 under the Securities Act. Persons who may be deemed to be affiliates of Parent include individuals or entities that control, are controlled by, or are under common control with, Parent and may include the executive officers, directors and significant shareholders of Parent.

First Bexley shareholder appraisal rights

The following is a summary of the steps that you must take if you wish to exercise dissenters’ rights with respect to the Merger. This description is not complete. You should read the provisions of 12 U.S.C. Section 215a(b) through (d) and Sections 1115.19 and 1701.85 of the ORC, which are set forth in Annex B to this prospectus/proxy statement, for a more complete discussion of the procedures. If you fail to take any one of the required steps set forth in these provisions, your dissenters’ rights may be terminated. If you are considering dissenting, you should consult your own legal advisor.

To exercise dissenters’ rights, you must:

All written notices and requests should be sent to The First Bexley Bank, 2680 East Main Street, Bexley, Ohio 43209, Attention: David Mallet, President and Chief Executive Officer.

TABLE OF CONTENTS

If you properly exercise dissenters’ rights pursuant to 12 U.S.C. Section 215a(b), the “fair cash value” of your First Bexley common shares will be determined in accordance with Sections 1115.19 and 1701.85 of the ORC. The “fair cash value” is the amount that a willing seller, who is under no compulsion to sell, would be willing to accept, and that a willing buyer, under no compulsion to purchase, would be willing to pay. Fair cash value is determined as of the day before the special meeting, excluding any appreciation or depreciation in market value of your First Bexley common shares resulting from the Merger. The fair cash value of your First Bexley common shares may be higher, the same as, or lower than the market value of First Bexley common shares on the date of the Merger. In no event will the fair cash value be in excess of the amount specified in the dissenting shareholder’s request for payment of the fair cash value.

If you do not reach an agreement as to the fair cash value of your First Bexley common shares with First Financial, as successor by Merger to First Bexley, you may file a complaint with the Court of Common Pleas of Franklin County, Ohio, for a determination of the fair cash value of the dissenting shares within three months after service of your written request to First Bexley for payment of the fair cash value. The court will then determine the fair cash value per share, and the costs of the proceeding, including reasonable compensation to appraisers, will be assessed as the court considers equitable in accordance with Sections 1115.19 and 1701.85 of the ORC.

Your right to receive the fair cash value of your dissenting shares will terminate if:

TABLE OF CONTENTS

DESCRIPTION OF THE MERGER AGREEMENT

The following is a summary of the material terms of the Merger Agreement. This summary does not purport to describe all the terms of the Merger Agreement and is qualified by reference to the complete text of the Merger Agreement which is attached as Annex A to this proxy statement/prospectus and is incorporated by reference into this proxy statement/prospectus. You should read the Merger Agreement completely and carefully as it, rather than this description, is the legal document that governs the Merger.

The text of the Merger Agreement has been included to provide you with information regarding its terms. The terms of the Merger Agreement (such as the representations and warranties) are intended to govern the contractual rights and relationships, and allocate risks, between the parties in relation to the Merger. The Merger Agreement contains representations and warranties Parent and First Financial, on the one hand, and First Bexley, on the other hand, made to each other as of specific dates. The representations and warranties were negotiated between the parties with the principal purpose of setting forth their respective rights with respect to their obligations to complete the Merger. The statements embodied in those representations and warranties may be subject to important limitations and qualifications as set forth therein, including a contractual standard of materiality different from that generally applicable under federal securities laws.

General

The Merger Agreement provides for the Merger of First Bexley with and into First Financial, with First Financial continuing as the surviving bank. After the consummation of the Merger, First Financial will continue to be a wholly owned subsidiary of Parent.

Closing and effective time

Closing.  The closing of the Merger will take place on a date, to be specified by the parties, no later than the first Friday that is also a business day after satisfaction or waiver of the conditions set forth in the Merger Agreement, or at another time agreed to in writing by all the parties. See “— Conditions to completion of the Merger” below for a more complete description of the conditions that must be satisfied prior to closing. The completion of the Merger sometimes is referred to in this proxy statement/prospectus as the closing date.

Completion of the Merger.  The Merger will become effective upon the filing of the certificate of merger with the Ohio Secretary of State, or such time thereafter as agreed to in writing by Parent and First Financial and so provided in the certificate of merger. The time at which the Merger becomes effective is sometimes referred to in this proxy statement/prospectus as the effective time.

Consideration to be received in the Merger

First Bexley Common Stock and Cash Consideration.  If the Merger is completed, each share of First Bexley common stock that you own immediately before the completion of the Merger will be converted into the right to receive a combination of cash and shares of Parent common stock. All outstanding stock options of First Bexley will be cashed out at the closing of the Merger. Including payment to be made for cancelling the stock options, the expanded total merger consideration is valued at approximately $44.5 million.

For each of your shares of First Bexley common stock, you will receive the per share merger consideration equal to $30.50 in the form of a combination of cash and shares of Parent common stock to be calculated as set forth in the Merger Agreement. Of such per share merger consideration, 20%, or $6.10, will be paid in cash and 80%, or $24.40, will be paid in Parent’s common stock (including cash to be paid in lieu of any fractional shares), subject to certain adjustment depending upon changes in the market price of Parent’s common stock. The exchange ratio used to determine the number of shares of Parent common stock that you will be entitled to receive for each share of First Bexley common stock will be determined based on the average closing price on Nasdaq for the twenty trading days ending on the third business day prior to the effective time of the Merger (the “Parent Share Average Closing Price”), subject to a minimum and maximum price equal to $13.80 and $18.66, respectively, and certain further adjustment. Based on an Parent Share Average Closing Price of $    , which is equal to the Parent Share Average Closing Price if it were calculated as if the closing date was           , 2014, the latest practicable date prior to the date of this proxy statement/prospectus, the merger consideration that a First Bexley shareholder would be entitled to

TABLE OF CONTENTS

receive for each share of First Bexley common stock is $6.10 in cash and      shares of Parent common stock. If the Parent Share Average Closing Price were equal to the minimum of $13.80, each share of First Bexley common stock would instead be entitled to $6.10 in cash and 1.7681 shares of Parent common stock; if the Parent Share Average Closing Price were equal to the maximum of $18.66, each share of First Bexley common stock would be entitled to $6.10 in cash and 1.3076 shares of Parent common stock. For a description of how the merger consideration will be calculated, see “Description of the Merger Agreement — Consideration to be received in the Merger”.

The following table illustrates the per share value of merger consideration that First Bexley’s shareholders will receive in the Merger based on a range of Parent Share Average Closing Prices, assuming the currently outstanding      shares of First Bexley common stock remain unchanged immediately prior to the effective time of the Merger. The table is for illustrative purposes only. The actual prices at which Parent common stock trades during the twenty trading days ending on the third business day prior to the effective time of the Merger will establish the actual Parent Share Average Closing Prices and therefore the actual exchange ratio for the stock component of the merger consideration. The actual trading price of Parent common stock is subject to market fluctuations.

Stock Consideration Ratio Adjustment.  If the Parent Share Average Closing Price is less than $13.80, First Bexley may reduce the ratio of the stock component of the merger consideration from 80% to no less than 75%. On the other hand, if the Parent Share Average Closing Price is more than $18.66, First Financial may reduce the ratio of the stock component of the merger consideration from 80% to no less than 75%. No such reduction is permitted if it would result in a failure of the Merger being a tax-free reorganization.

Tax Adjustment.  In order to preserve the tax-free reorganization qualification of the Merger, if the aggregate value of the shares of Parent common stock to be issued in connection with the Merger (excluding

TABLE OF CONTENTS

the value of fractional shares for which cash is to be paid) based upon the closing price of the Parent common stock as reported on Nasdaq the trading day immediately preceding the closing date of the Merger (the “Tax Adjuster Stock Consideration”) would be less than 40% of the sum of the Tax-Adjuster Cash Consideration (as defined below) and the Tax-Adjuster Stock Consideration, then the exchange ratio for the stock component of the merger consideration will be adjusted so that the Tax-Adjuster Stock Consideration is equal to 40% of the sum of the Tax-Adjuster Stock Consideration and the Tax-Adjuster Cash Consideration without changing the value of the total merger consideration. For purposes of the above, “Tax-Adjuster Cash Consideration” means the sum of (i) the aggregate cash consideration to be paid in exchange for the First Bexley common stock (including, without limitation, the cash paid for appraisal shares) and (ii) the aggregate cash consideration to be paid in lieu of fractional shares. Assuming the Parent Share Average Closing Price is equal to $    , each share of First Bexley common stock would be entitled to $6.10 in cash and      shares of Parent common stock; however, if the closing price of the Parent common stock as reported on Nasdaq on the trading day immediately preceding the closing date of the Merger falls below $2.30, adjustment will be made to preserve the tax-free qualification (assuming no cash paid for appraisal shares and no other adjustment made by the parties, and disregarding the effect of cash consideration to be paid in lieu of fractional shares, for purpose of illustration). For example, under these assumptions, if the above-referenced closing price of the Parent common stock falls to $2.25, each share of First Bexley common stock would be entitled to $18.30 in cash and 5.4223 shares of Parent common stock.

Kill or Fill Adjustment.  If the Parent Share Average Closing Price has declined by more than 25% from the average closing price on Nasdaq for the twenty trading days ending on the third business day prior to the date of the Merger Agreement, which is $16.23, and the Parent common stock underperforms the KBW Regional Banking Index by more than 25% during such period, First Bexley may terminate the Merger Agreement unless Parent removes the Collar Restriction in calculating the exchange ratio for the stock component of the merger consideration.

Fractional shares

No fractional shares of Parent common stock will be issued in the Merger. Instead, Parent will pay to each holder of First Bexley common stock who would otherwise be entitled to a fractional share of Parent common stock an amount in cash (without interest) rounded to the nearest whole cent, determined by multiplying the Parent Share Average Closing Price by such fraction of a share of Parent common stock to which such First Bexley shareholder would otherwise be entitled.

Cash-Out of Stock Options

At the effective time, all rights with respect to the underlying First Bexley common stock of the stock options granted by First Bexley will be converted into the rights to receive cash only. The Merger Agreement requires First Bexley to enter into option cash-out agreements with all its stock option holders to ensure that, immediately prior to the effective time, each First Bexley stock option, whether or not then exercisable, be cancelled at the effective time and only entitle the holders to receive a cash amount. Such cash amount will be equal to the difference between the exercise price for the stock option and the merger consideration to which the applicable underlying stock would otherwise be entitled, less applicable taxes required to be withheld with respect to such payment. At the Effective Time, each First Bexley stock option to purchase a share of First Bexley common stock whether or not then exercisable shall terminate and be of no further effect and any rights thereunder to purchase shares of First Bexley Common Stock shall also terminate and be of no further force or effect.

Exchange of certificates

First Financial will engage U.S. Bank National Association to act as its exchange agent to handle the exchange of First Bexley common stock for the merger consideration and the payment of cash for any fractional share interest. As promptly as practicable after the effective time, the exchange agent will send to each First Bexley shareholder a letter of transmittal for use in the exchange with instructions explaining how to surrender First Bexley common stock certificates to the exchange agent. First Bexley shareholders that surrender their certificates to the exchange agent, together with a properly completed letter of transmittal, will receive the merger consideration. First Bexley shareholders that do not exchange their First Bexley common

TABLE OF CONTENTS

stock will not be entitled to receive the merger consideration or any dividends or other distributions by Parent until their certificates are surrendered. After surrender of the certificates representing First Bexley shares, any unpaid dividends or distributions with respect to the Parent common stock represented by the certificates will be paid without interest.

Conduct of business pending the Merger and certain covenants

Under the Merger Agreement, First Bexley has agreed to certain restrictions on its activities and the activities of its subsidiaries until the Merger is completed or the Merger Agreement is terminated. In general, First Bexley and its subsidiaries are required to maintain their existence, conduct their business and operations in the ordinary course of business and in a manner consistent with prior practice, and use commercially reasonable efforts to keep available the services of its current officers and employees and preserve the rights, franchises, goodwill and relations of its customers, clients and others with whom business relationships exist.

The following is a summary of the more significant restrictions imposed upon First Bexley, subject to the exceptions set forth in the Merger Agreement. First Bexley will not, and will cause its subsidiaries not to, without Parent and First Financial’s prior written consent:

TABLE OF CONTENTS

Parent has also agreed to certain restrictions on its activities and the activities of its subsidiaries until the Merger is completed or the Merger Agreement is terminated. Subject to the exceptions set forth in the Merger Agreement, Parent will not, and will cause its subsidiaries not to, without First Bexley’s prior written consent:

First Bexley, Parent and First Financial have each agreed to use its reasonable best efforts to take all actions and to do all things necessary, proper or advisable to fulfill all closing conditions applicable to such party pursuant to the Merger Agreement and to complete the Merger in the most expeditious manner practicable, including:

First Bexley, on the one side, and Parent and First Financial, on the other side, have agreed:

The Merger Agreement also contains certain covenants relating to employee benefits and other matters pertaining to officers and directors. See “— Employee benefit matters” and “The Merger — Interests of certain persons in the Merger.”

No solicitation of transaction or change of recommendation

No solicitation.  The Merger Agreement contains provisions prohibiting First Bexley from seeking or discussing an alternative acquisition proposal to the Merger. First Bexley has agreed that it will not, and will use reasonable best effort to cause its representatives not to, directly or indirectly, (i) solicit, initiate, encourage or knowingly facilitate any alternative acquisition proposal, (ii) discuss or negotiate any alternative acquisition proposal or give any other person any information of First Bexley relating to an alternative acquisition proposal, (iii) approve, endorse or recommend any alternative acquisition proposal, or (iv) enter into any agreement relating to an alternative acquisition proposal. Upon execution of the Merger Agreement, First Bexley is required to immediately cease any communications with any party with respect to any

TABLE OF CONTENTS

alternative acquisition proposal, but is not prohibited from contacting any party solely for the purpose of complying with the above requirements or to enforce the provisions of any confidentiality agreement with respect to an alternative acquisition proposal.

Notwithstanding the restrictions described above, the Merger Agreement provides that First Bexley may discuss or negotiate an alternative acquisition proposal or give other person information of First Bexley relating to an alternative acquisition proposal if, but only if, (i) First Bexley has received a bona fide unsolicited written alternative acquisition proposal prior to First Bexley shareholders’ meeting; (ii) First Bexley’s board of directors determines that such alternative acquisition proposal constitutes a superior proposal as compared with the Merger; (iii) First Bexley has provided First Financial with at least five business days’ prior notice of such determination; (iv) prior to furnishing or affording access to any information of First Bexley relating to an alternative acquisition proposal, First Bexley receives from such person certain confidentiality agreements; and (v) the failure of First Bexley’s board of directors to furnish such information or enter into discussions or negotiations would violate its fiduciary duties to First Bexley shareholders. First Bexley is required to promptly notify First Financial if any proposals are received by, any information is requested from, or any negotiations are sought from, First Bexley in connection with any alternative acquisition proposal. First Bexley is also required to promptly provide to First Financial any information it provides to any other that was not previously provided to First Financial.

No change of recommendation.  The Merger Agreement requires First Bexley’s board of directors to use reasonable best efforts to seek First Bexley shareholders’ approval of the Merger, but First Bexley’s board of directors may change its recommendation for shareholders’ approval of the Merger if, and only if, (i) based upon the written advice of its outside legal counsel and independent financial advisor, the board has received a superior proposal; (ii) based upon the written advice of such outside legal counsel, a failure to accept such superior proposal would result in the board breaching its fiduciary duties to First Bexley and its shareholders; (iii) the board notifies First Financial in advance of its intent to change its recommendation and the terms of the superior proposal; and (iv) after providing First Financial a reasonable opportunity to renegotiate and adjust the terms and conditions of the Merger Agreement, the board again determines, based upon the written advice of its outside legal counsel and such independent financial advisor, that such alternative acquisition proposal nonetheless continues to constitute a superior proposal and that failure to change its recommendation would violate its fiduciary duties to First Bexley and First Bexley shareholders. However, First Bexley’s board of directors is prohibited form changing its recommendation if First Financial has offered to modify the terms of the Merger Agreement to provide for substantially identical terms and conditions as superior proposal.

As used above, “superior proposal” refers to any bona fide written acquisition proposal made by a third party, which, as determined by First Bexley’s board of directors determines in its good faith judgment, based upon the written advice of its outside legal counsel and an independent financial advisor, (i) would result in the acquisition of all of First Bexley common stock or all, or substantially all, of the assets of First Bexley and its subsidiaries; (ii) would result in a transaction that (A) involves consideration to the holders of First Bexley common stock that is more favorable, from a financial point of view, than the consideration to be paid to First Bexley’s shareholders pursuant to the Merger Agreement, considering, among other things, the nature of the consideration being offered and any material regulatory approvals or other risks associated with the timing of the proposed transaction beyond or in addition to those specifically contemplated hereby, and (B) is, in light of the other terms of such proposal, more favorable to First Bexley shareholders than the Merger; and (iii) is reasonably likely to be completed.

Representations and warranties

The Merger Agreement contains representations and warranties made by First Bexley, Parent and First Financial. These include, among other things, representations relating to:

Termination

First Financial and First Bexley may mutually agree to terminate the Merger Agreement and abandon the Merger at any time.

Termination fee

First Bexley has also agreed to pay First Financial for its out-of-pocket expenses incurred in connection with the proposed Merger if the Merger Agreement is terminated by any party because the First Bexley shareholders fail to adopt the Merger Agreement.

TABLE OF CONTENTS

Management of Parent, First Financial and First Bexley after the Merger

After the Merger, First Financial board of directors will continue to serve as the directors of the surviving bank. At or promptly following the effective time of the Merger, Parent will appoint one qualified, independent director designated by First Bexley to serve on Parent’s board of directors.

In addition, at or promptly following the effective time, Parent will create a Columbus advisory board and appoint certain director or directors from the current board of directors of First Bexley, as agreed among Parent, First Financial and First Bexley, to serve on the Columbus advisory board.

Employee benefit matters

Pursuant to the Merger Agreement, Parent and First Financial have the sole discretion in determining which employees of First Bexley will continue employment with the surviving bank following the closing date. Each continuing employee will be provided wages or salaries and employee benefits (excluding equity plans) that in the aggregate are substantially comparable to what he or she receives at First Bexley immediately prior to the closing date.

Parent and First Financial will provide each employee of First Bexley who does not continue employment with the surviving bank with severance benefits under First Financial’s existing severance practices or pursuant to the terms of any applicable employment agreement with First Bexley in existence as of the date of the Merger Agreement. For purposes of determining seniority as it relates to First Financial’s severance practices, each discontinued employee will be credited with his or her years of service with First Bexley.

Expenses

Each party to this Agreement will bear its own expenses incurred in connection with the Merger Agreement. As more fully described above under “— Termination fee,” First Bexley has also agreed to reimburse First Financial for certain out-of-pocket expenses in the event the Merger is terminated for certain specified reasons.

Nasdaq stock listing

Parent common stock currently is listed on Nasdaq under the symbol “FFBC.” The shares to be issued to First Bexley’s shareholders as merger consideration also will be eligible for trading on Nasdaq. Parent 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 shares of Parent common stock 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.

Amendment

The Merger Agreement may not be amended except by a written instrument executed by all parties.

COMPARISON OF RIGHTS OF PARENT SHAREHOLDERS AND FIRST
BEXLEY SHAREHOLDERS

General

First Bexley shareholders who receive Parent common shares as consideration in the Merger will become shareholders of Parent at the effective time of the Merger. Parent is an Ohio corporation and a bank holding company registered under the Bank Holding Company Act of 1956, as amended, while First Bexley is an Ohio state-chartered commercial bank. Although the rights of the holders of Parent common shares and those of holders of First Bexley common shares are similar in many respects, there are some differences. These differences relate to differences between the provisions of Ohio law governing corporations and the provisions of Ohio law governing state-chartered commercial banks, as well as differences between provisions of Parent’s articles of incorporation and regulations and the First Bexley’s articles of incorporation, bylaws and code of regulations.

Set forth below is a summary of the material differences between the rights of Parent shareholders and the rights of First Bexley shareholders. This description is not intended to be a complete statement of the differences affecting the rights of First Bexley shareholders, but rather describes the more significant differences affecting the rights of First Bexley shareholders and certain important similarities. This description is qualified in its entirety by reference to the relevant provisions of Ohio law and the articles of incorporation and regulations of each of First Bexley and Parent.

		Parent Shareholder Rights		First Bexley Shareholder Rights
Authorized Capital Stock:		Parent is authorized to issue 160 million shares of common stock, without par value, and 80,000 shares of preferred stock, without par value.   On February 24, 2014, Parent had 57,510,991 shares of common stock outstanding and no shares of preferred stock outstanding.   Parent common stock is listed on Nasdaq under the symbol “FFBC.”		First Bexley is authorized to issue 18 million shares of common stock, without par value, and two million shares of preferred stock, without par value.   On February 24, 2014, First Bexley had 1,381,239 shares of common stock outstanding and no shares of preferred stock.   There exists no established trading market for First Bexley common stock.

TABLE OF CONTENTS

		Parent Shareholder Rights		First Bexley Shareholder Rights
Issuance of Preferred Stock		Parent’s board of directors is authorized, by filing articles of amendment, to provide for the issuance of preferred stock in series pursuant to, and only pursuant to, the terms of any capital purchase program(s) authorized by the Emergency Economic Stabilization Act of 2008 (“EESA”) and implemented by the United States Department of the Treasury (the “Treasury”), and to fix the designations, powers, preferences and rights thereof in compliance with any EESA program. Subject to the above limitations, Parent, board of directors has the authority to determine and fix any express terms with respect to each series to the fullest extent permitted by the ORC.		First Bexley’s board of directors is authorized to provide for the issuance of the preferred stock in series and, by filing a certificate pursuant to applicable Ohio law, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each such series and the qualifications, limitations and restrictions thereof.
Dividends:		Subject to any rights of holders of Parent preferred stock, the holders of Parent common stock are entitled to receive dividends, if and when declared payable from time to time by Parent’s board of directors, from any funds legally available therefor.   However, the Federal Reserve Board expects Parent, as a bank holding company, to serve as a source of strength to its subsidiary banks, which may require Parent to retain capital for further investments in its subsidiary banks, rather than for dividends for its shareholders.		Subject to any rights of holders of First Bexley preferred stock, the holders of First Bexley common stock are entitled to receive dividends only when and as declared from time to time by the First Bexley board of directors in amounts not exceeding those permitted by Ohio law.   In particular, First Bexley is required to obtain the approval of the Ohio Division of Financial Institutions before declaring and paying a dividend if a dividend in any year would cause the total dividends and distributions for that year, and not paid in shares, to exceed the sum of First Bexley’s net income for that year and its retained net income of the preceding two years.

TABLE OF CONTENTS

		Parent Shareholder Rights		First Bexley Shareholder Rights
Number of Directors, Classification:		Parent’s board of directors currently consists of 12 members. Parent’s regulations provide, however, that the number may be increased or decreased (provided the number is never less than nine or more than 25) by resolution of the board of directors (by vote of two-thirds of the whole authorized number of directors) or by resolution of the shareholders at a meeting of shareholders for electing directors (by vote of two-thirds of the outstanding voting power). Following the Merger, the number of directors of Parent will be increased by one for a new director to be designated by First Bexley.   Parent’s board of directors consists of a single class of directors.		First Bexley’s board of directors currently consists of eight members. First Bexley’s regulations provide, however, that the number may be increased or decreased (provided the number is never less than five or more than 15) by resolution of the shareholders holding at least ¾ of First Bexley’s voting power, or by resolution of at least  2/3 of the board of directors plus the majority of the outstanding voting power of the shareholders. The directors may also change the number of directors by the vote of  2/3 of the authorized number of directors and may fill any director’s office that is created by an increase in the number of directors; provided, that the directors may not increase the number of directors to more than 15, reduce the number of directors to less than five, or change the number of directors by more than two from the number last fixed by the shareholders.   First Bexley’s board of directors consists of two classes designated Class I and Class II.
Removal of Directors:		A Parent director may be removed for cause.		A First Bexley director may be removed with or without cause by the shareholders holding 75% of the voting power of First Bexley entitling them to elect directors in place of those to be removed.

TABLE OF CONTENTS

		Parent Shareholder Rights		First Bexley Shareholder Rights
Limitation on Director Liability and Indemnification:		Parent’s articles of incorporation provide that each person who is or was a director, officer, employee or agent of the corporation will be indemnified by Parent to the full extent permitted by the ORC against any liability, cost or expense incurred in such capacity, or arising out of such status. Parent may, but is not obligated to, maintain insurance, at its expense, to protect itself and any such person against any such liability, cost or expense.   Parent’s regulations provide that Parent shall, to the full extent permitted by law, indemnify all persons whom it may indemnify.		First Bexley’s regulations provide that any present or former director or officer will be indemnified if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of First Bexley, and with respect to any criminal action or proceeding, he had no reasonable cause to believe his conduct was unlawful. First Bexley shall make any indemnification only upon a determination that such indemnification is proper in the circumstances.
Advance Notice Regarding Shareholders Nomination of Candidates for Election to the Board of Directors:		Parent’s regulations provide that nomination for election of directors may be made by any shareholder by delivering written notice to the Secretary of Parent not later than (i) for annual meeting of shareholders, 90 days prior to the date one year from the date of the immediately preceding annual meeting of shareholders, and (ii) for special meeting of shareholders, the close of business on the tenth day following the date on which notice of such meeting is first given to shareholders.   The notice shall set forth the information about the nominee specified in Parent’s regulations. Parent may also require any proposed nominee to furnish other information reasonably required by Parent to determine the proposed nominee’s eligibility to serve as a director.		Nominations, other than those made by or at the direction of the board, shall be made in writing and must be delivered or mailed to the President of First Bexley not less than 14 nor more than 50 days prior to any meeting of shareholders called for the purpose of electing directors; provided, that if less than 21 days’ notice is given to shareholders, such nomination must be mailed or delivered to the President no later than the close of business on the seventh day following the day on which notice of the meeting was made.   The notice shall set forth the information about the nominee specified in First Bexley’s regulations.

TABLE OF CONTENTS

		Parent Shareholder Rights		First Bexley Shareholder Rights
Required Vote for Certain Transactions		Parent’s articles of incorporation and regulations do not specifically discuss transactions involving merger, consolidation, or sale, lease or exchange of all or substantially all of the property or assets of the corporation.		First Bexley’s articles of incorporation provides that, unless two-thirds of the whole authorized number of directors recommends the approval of any of the following matters, the vote of the holders of shares entitling them to exercise not less than 75% of the voting power entitled to vote are required to adopt: (a) amendment to articles of incorporation, (b) an agreement of merger or consolidation, (c) a proposed combination or majority share acquisition involving the issuance of shares and requiring shareholder approval, (d) sale, lease, or exchange of all or substantially all assets, or (e) change of the number of directors.
Amendment to Articles of Incorporation and Regulations		Parent’s articles of incorporation do not specifically provide for its amendment and, therefore, may be amended in accordance with the ORC.   Parent’s regulations provide that the regulations may be amended only by the vote of the holders of two-thirds of the outstanding voting power of Parent voting as a single class at a meeting of shareholders called for such purpose, unless such amendment is recommended by the vote of two-thirds of the whole authorized number of directors, in which case the regulations may be amended by the affirmative vote of the holders of a majority of the outstanding voting power voting as a single class at a meeting of shareholders called for such purpose.		First Bexley’s articles of incorporation require the approval of  2/3 of the whole authorized number of directors or the affirmative vote of the shareholders holding 75% of First Bexley’s voting power to amend the articles of incorporation or adopt amended articles.   First Bexley’s bylaws may be amended at any meeting of the board of directors by a  2/3 vote of the directors present provided all proposals to amend the bylaws will be made in writing at a meeting of the board at least 10 days before action is taken.   First Bexley’s regulations do not specifically provide for its amendment and, therefore, may be amended in accordance with the ORC.

Certain anti-takeover effects of Parent’s articles of incorporations and regulations

Certain provisions of Parent’s articles of incorporation and regulations may have the effect of impeding the acquisition of control of Parent by means of a tender offer, a proxy fight, open-market purchases or otherwise in a transaction not approved by Parent’s board of directors.

These provisions may have the effect of discouraging a future takeover attempt which is not approved by Parent’s board of directors but which individual Parent shareholders may deem to be in their best interests or in which Parent shareholders may receive a substantial premium for their shares over then-current market prices. As a result, shareholders who might desire to participate in such a transaction may not have an opportunity to do so. Such provisions will also render the removal of Parent’s current board of directors or management more difficult.

TABLE OF CONTENTS

These provisions of Parent’s articles of incorporation and by-laws include the following:

The provisions described above are intended to reduce Parent’s vulnerability to takeover attempts and certain other transactions which have not been negotiated with and approved by members of Parent’s board of directors.

Anti-takeover statutes

Certain state laws make a change in control of an Ohio corporation more difficult, even if desired by the holders of a majority of the corporation’s shares. Provided below is a summary of the Ohio anti-takeover statutes.

Ohio Control Share Acquisition Statute.  Section 1701.831 of the ORC, known as the “Ohio Control Share Acquisition Statute,” provides that specified notice and informational filings and special shareholder meetings and voting procedures must occur before consummation of a proposed “control share acquisition.” A control share acquisition is defined as any acquisition of shares of an “issuing public corporation” that would entitle the acquirer, directly or indirectly, alone or with others, to exercise or direct the exercise of the voting power of the issuing public corporation in the election of directors within any of the following ranges:

An “issuing public corporation” is an Ohio corporation with 50 or more shareholders that has its principal place of business, principal executive offices, assets having substantial value, or a substantial percentage of its assets within the State of Ohio, and as to which no valid close corporation agreement exists. Assuming compliance with the notice and informational filing requirements prescribed by the Ohio Control Share Acquisition Statute, the proposed control share acquisition may take place only if, at a duly convened special meeting of shareholders, the acquisition is approved by both:

TABLE OF CONTENTS

The Ohio Control Share Acquisition Statute permits a corporation to opt out of the application of the statute in its articles of incorporation or regulations. Neither Parent nor First Bexley has opted out of the application of the Ohio Control Share Acquisition Statute in their respective articles of incorporation or regulations.

Ohio Merger Moratorium Statute.  Chapter 1704 of the ORC, known as the “Ohio Merger Moratorium Statute,” prohibits specified business combinations and transactions between an issuing public corporation and a beneficial owner of shares representing 10% or more of the voting power of the corporation in the election of directors (an “interested shareholder”) for at least three years after the interested shareholder became such, unless the board of directors of the issuing public corporation approves either (1) the transaction or (2) the acquisition of the corporation’s shares that resulted in the person becoming an interested shareholder, in each case before the interested shareholder became such.

For three years after a person becomes an interested shareholder, the following transactions between the corporation and the interested shareholder (or persons related to the interested shareholder) are prohibited:

After the three-year period, transactions between the corporation and the interested shareholder are permitted if:

A corporation may elect not to be covered by the provisions of the Ohio Merger Moratorium Statute by the adoption of an appropriate amendment to its articles of incorporation. Neither Parent nor First Bexley has opted out of the Ohio Merger Moratorium Statute. However, the Ohio Merger Moratorium Statute does not apply to the Merger because First Bexley (1) is not an interested shareholder of Parent, and (2) is not an affiliate or associate of an interested shareholder and will not be an affiliate or associate after the Merger, as such terms are defined in the Ohio Merger Moratorium Statute.
