This prospectus describes the general terms of the securities we may offer and the general manner in which we may offer the securities. Each time we offer securities under this prospectus, we will provide a prospectus supplement that will describe the specific terms of the securities offered and the specific manner in which we will offer the securities. A prospectus supplement may include a discussion of any risk factors or other special considerations applicable to those securities or to us. The prospectus supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement, you should rely on the information in the applicable prospectus supplement.

FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated herein by reference may contain certain statements that are not statements of historical fact, but, rather, constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, without limitation, the statements specifically identified as forward-looking statements within this prospectus. Examples of forward-looking statements include: (i) projections of income or expense, earnings per share, the payment or non-payment of dividends, capital structure and other financial items; (ii) statements of our plans and objectives or our management or Board of Directors, including those relating to products or services; (iii) statements of future economic performance; and (iv) statements of assumptions underlying such statements. Words such as “believes,” “anticipates,” “expects,” “intends,” “targeted” and similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying those statements.

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements to encourage companies to provide prospective information so long as those statements are identified as forward-looking and are accompanied by meaningful cautionary statements identifying important factors that could cause actual results to differ materially from those discussed in the forward-looking statements. We desire to take advantage of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995.

Forward-looking statements involve risks and uncertainties. Actual results may differ materially from those predicted by the forward-looking statements because of various factors and possible events, including those factors and events identified (i) in “Item 1A. Risk Factors” of the Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and (ii) in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of First Financial’s 2016 Annual Report (included within Exhibit 13 to the Annual Report on Form 10-K).

Forward-looking statements speak only as of the date on which they are made, and, except as may be required by law, we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made to reflect unanticipated events. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are qualified in their entirety by the foregoing cautionary statements. You are advised, however, to consult any further disclosures we make on related subjects in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with or furnished to the SEC. Also note that we provide cautionary discussion of risks, uncertainties and possibly inaccurate assumptions relevant to our business in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K incorporated by reference herein and in prospectus supplements, pricing supplements and other offering materials. These are factors that, individually or in the aggregate, management believes could cause our actual results to differ materially from expected and historical results. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider such disclosures to be a complete discussion of all potential risks or uncertainties.

DESCRIPTION OF DEBT SECURITIES

For purposes of this section, the terms “we,” “our” and “us” refer only to First Financial and not its subsidiaries. The following description of the debt securities sets forth certain general terms that may apply to the debt securities that we may offer under this prospectus. The debt securities may be issued as senior debt securities or subordinated debt securities. Unless otherwise specified in the applicable prospectus supplement, we may issue senior debt securities under a senior indenture (the “senior indenture”), which we will enter into with a trustee to be named in the senior indenture. Prior to issuing any debt securities under such senior indenture, we will select the trustee for the senior indenture (the “senior indenture trustee”) relating to the issuance of senior debt securities, qualify the senior indenture trustee under the Trust Indenture Act and execute such senior indenture. We also may issue subordinated debt securities in one or more series under the Subordinated Indenture, dated April 25, 2015 (the “subordinated indenture”), between First Financial and Wells Fargo Bank, National Association (“Wells Fargo”), and the related supplemental indenture for such subordinated debt securities. Each of the senior indenture trustee and Wells Fargo is referred to as the “indenture trustee,” unless otherwise specified.

The senior indenture and subordinated indenture are sometimes collectively referred to as the “indentures” and individually referred to as an “indenture,” and the senior debt securities and the subordinated debt securities are sometimes referred to as the “debt securities.” The indentures are subject to and governed by the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The form of senior indenture and the subordinated indenture are incorporated by reference in the registration statement of which this prospectus is a part.

The following summary of the terms of the indentures is subject to, and qualified in its entirety by reference to, the indentures, which contain the full legal text of the matters described in this section, and the description of the specific terms of the debt securities in the applicable prospectus supplement. The following summary is not complete. You should read all of the provisions of the indentures, including the definitions of certain terms.

Since we are a holding company, our right, and accordingly, the right of our creditors and shareholders, including the holders of the securities offered by this prospectus and any prospectus supplement, to participate in any distribution of assets of any of our subsidiaries upon its liquidation, reorganization or similar proceeding is subject to the prior claims of creditors of that subsidiary, except to the extent that our claims as a creditor of the subsidiary may be recognized.

Terms of the Securities

The debt securities will not be secured by any of our assets. All of the debt securities issued under each of the indentures will rank equally and ratably with any additional debt securities issued under the same indenture. The subordinated debt securities will be subordinated as described below under the heading “Subordination.”

The indentures give us broad authority to set the particular terms of each series of debt securities, including the right to modify certain of the terms contained in the applicable indenture. We will describe the specific terms of a series of debt securities and the extent, if any, to which the specific terms of the debt securities modify the terms of the applicable indenture in the prospectus supplement relating to the debt securities.

Neither the indentures nor the debt securities limit or otherwise restrict the amounts of other indebtedness that we may incur, or the amount of other securities that we may issue. The indentures do not limit the principal amount of any particular series of debt securities. Each prospectus supplement will specify the particular terms of the debt securities being offered, including the following, as may be applicable:

•

​

​

Some of our debt securities may be issued as “original issue discount” securities. Original issue discount securities bear no interest or bear interest at below-market rates and will be sold at a discount below their stated principal amount. The prospectus supplement will also contain any special tax, accounting or other information relating to original issue discount securities or relating to certain other kinds of securities that may be offered, including securities linked to an index.

Acceleration of Maturity

If an event of default with respect to any outstanding series of debt securities occurs and is continuing, the indenture trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount due and payable immediately by providing written notice of such acceleration to us, and, if notice is given by the holders instead of the indenture trustee, to the indenture trustee. Under the subordinated indenture, all outstanding subordinated debt securities will become immediately due and payable, only upon the following events of default:

•

a decree or order is entered against us in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official is appointed for us, certain of our subsidiary banks, or a substantial part of our property, or a receiver or similar official is appointed by a court or a bank regulatory authority, or a court or administrative order is entered for the winding-up or liquidation of our affairs or those of certain of our subsidiary banks, and such decree or order remains unstayed and in effect for 60 consecutive days; or

​

•

We (a) commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, (b) consent to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of us, certain of our subsidiary banks or for any substantial part of our property, (c) make any general assignment for the benefit of creditors, (d) fail generally to pay our debts as they become due or (e) take any corporate action in furtherance of any of the foregoing.

​

Subject to certain conditions, the declaration of acceleration may be rescinded, and past defaults (except uncured payment defaults and certain other specified defaults) may be waived, by the holders of not less than a majority of the principal amount of debt securities of that series. You should refer to the prospectus supplement relating to each series of debt securities for the particular provisions relating to acceleration of maturity upon the occurrence and continuation of an event of default.

Registration and Transfer

We will issue the subordinated debt securities in registered form only, without coupons.

Each series of senior debt securities will also be issued in registered form only, without coupons, unless otherwise indicated in the applicable prospectus supplement. The senior indenture allows us to issue the securities in bearer form, or in both registered and bearer form. Any securities issued in bearer form will

8

have interest coupons attached, unless they are issued as zero coupon securities. Securities in bearer form will not be offered, sold, resold or delivered in connection with their original issuance in the United States or to any United States person other than to offices of certain United States financial institutions located outside the United States.

Unless otherwise indicated in the applicable prospectus supplement, the debt securities we are offering will be issued in denominations of  $1,000 or an integral multiple of  $1,000. No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of an amount sufficient to cover any tax or other governmental charge payable in connection with a transfer or exchange.

Payment and Paying Agent

We will pay principal, interest and any premium on fully registered debt securities in the designated currency or currency unit at the office of a designated paying agent. At our option, payment of interest on fully registered debt securities may also be made by check mailed to the persons in whose names the debt securities are registered on the days specified in the indentures or any prospectus supplement.

With respect to senior debt securities issued in bearer form, we will pay principal, interest and any premium on such bearer senior debt securities in the designated currency or currency unit at the office of a designated paying agent or agents outside of the United States. Payments will be made at the offices of the paying agent in the United States only if the designated currency is United States dollars and payment outside of the United States is illegal or effectively precluded. If any amount payable on a debt security or coupon remains unclaimed at the end of two years after such amount became due and payable, the paying agent will release any unclaimed amounts, and the holder of the debt security or coupon will look only to us for payment.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global certificates (“Global Securities”) that will be deposited with a depositary to be identified in the applicable prospectus supplement. Global Securities may be issued in either temporary or permanent form. Global Securities representing subordinated debt securities must be issued in registered form only, whereas Global Securities representing senior debt securities may be issued in registered or bearer form. Global Securities in bearer form will be deposited with a depositary outside the United States. Unless and until it is exchanged in whole or in part for individual certificates evidencing senior debt securities in definitive form represented thereby, a bearer Global Security may not be transferred except as a whole by the depositary to a nominee of that depositary or by a nominee of that depositary to a depositary or another nominee of that depositary.

The specific terms of the depositary arrangements for each series of debt securities will be described in the applicable prospectus supplement.

Modification and Waiver

Modification with Consent of the Holders

Each indenture provides that modifications and amendments may be made by us and the indenture trustee with the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected by the amendment or modification. However, no modification or amendment may, without the consent of each holder affected:

•

change the stated maturity date of the debt security;

​

•

​

modify, except under limited circumstances, any provision of the applicable indenture relating to modification and amendment of the indenture, waiver of compliance with conditions and defaults thereunder or the right of a majority of holders to take action under the applicable indenture;

​

•

adversely affect any rights of conversion;

​

•

in the case of the subordinated indenture, alter the provisions regarding subordination of the subordinated debt securities, in any way that would be adverse to the holders of those securities; or

In addition to the above, no modification or amendment to the subordinated indenture or the rights of holders of subordinated debt securities may, without the consent of each holder of such subordinated debt securities affected:

•

change the maturity date of the principal of the subordinated debt security;

​

•

change the computation of the principal amount of the subordinated debt security on any date;

​

•

modify, except under limited circumstances, the right of a holder of subordinated debt securities to receive payments of the principal, premium, interest or any additional amounts due with respect to such subordinated debt securities on the maturity or stated maturity date (or the redemption date, in the case of redemption) and to institute suit for the enforcement of any payment thereof;

​

​

Waiver of Compliance or Default

The holders of a majority in principal amount of the outstanding debt securities of any series may waive compliance by us and the indenture trustee with certain provisions of the indentures. The holders of a majority in principal amount of the outstanding debt securities of any series may waive any past default under the applicable indenture with respect to that series, except a default in the payment of the principal, or any premium, interest, or additional amounts payable on a debt security of that series or in respect of a covenant or provision which under the terms of the applicable indenture cannot be modified or amended, without the consent of each affected holder.

Modification of Senior Debt Securities without Consent

With the senior indenture trustee, we may modify and amend any senior indenture without the consent of any holder of senior debt securities for any of the following purposes:

•

to name a successor entity to us;

​

•

to add to our covenants for the benefit of the holders of all or any series of senior debt securities;

​

10

•

​

​

•

to modify, eliminate or add to the provisions of any indenture to conform our or the senior indenture trustee’s obligations under the applicable indenture to the Trust Indenture Act.

​

Modification of Subordinated Debt Securities without Consent

Together with Wells Fargo, we may modify and amend any subordinated indenture without the consent of any holder of subordinated debt securities for any of the following purposes:

•

to name a successor entity to us;

​

•

to provide for the acceptance of an additional successor trustee with respect to one or more series of subordinated debt securities;

​

•

to add to our covenants and agreements for the benefit of the holders of all or any series of subordinated debt securities or to surrender any right or power conferred on us by the subordinated indenture, provided that such action shall not adversely affect the interests of the holders of outstanding subordinated securities;

​

•

to add or eliminate the events of default;

​

to secure the subordinated debt securities or add obligors;

​

•

to establish any form or terms, or to provide for the issuance, of any series of subordinated debt securities;

​

•

to provide for the issuance of subordinated debt securities in uncertificated form to replace certificated subordinated debt securities of any series;

​

•

to qualify or maintain qualification of the subordinated indenture under the Trust Indenture Act; or

​

•

to comply with the rules and regulations of any securities exchange or automated quotation system on which any of the subordinated debt securities may be listed or traded.

​

Calculation of Outstanding Debt Securities

To calculate whether the holders of a sufficient principal amount of the outstanding securities have given any request, demand, authorization, direction, notice, consent or waiver under any indenture:

•

in the case of original issue discount securities, the principal amount that may be included in the calculation is the amount of principal that would be declared to be due and payable upon a declaration of acceleration according to the terms of that original issue discount security as of the date of the calculation; and

​

11

•

any debt securities owned by us, or owned by any other obligor of the debt securities or any affiliate of ours or of any other obligor, should be disregarded and deemed not to be outstanding for purposes of the calculation.

​

Additional Provisions

Other than the duty to act with the required standard of care during an event of default, the indenture trustee is not obligated to exercise any of its rights or powers under the applicable indenture at the request or direction of any of the holders of the debt securities, unless the holders have offered the indenture trustee reasonable indemnification. Each indenture provides that the holders of a majority in principal amount of outstanding debt securities of any series may, in certain circumstances, direct the time, method and place of conducting any proceeding for any remedy available to the indenture trustee, or exercising any trust or other power conferred on the indenture trustee.

No holder of a debt security of any series will have the right to institute any proceeding for any remedy under the applicable indenture, unless:

•

the holder has provided the indenture trustee with written notice of a continuing event of default regarding the holder’s series of debt securities;

​

•

the holders of at least 25% in principal amount of the outstanding debt securities of a series have made a written request to the indenture trustee, and offered indemnity or security, as applicable, satisfactory to the indenture trustee, to institute a proceeding for remedy;

​

•

the indenture trustee has failed to institute the proceeding within 60 days after its receipt of such notice, request and offer of indemnity or security, as applicable; and

​

•

the indenture trustee has not received any direction during such 60-day period inconsistent with such request from the holders of a majority in principal amount of the outstanding debt securities of that series.

​

However, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal, any premium, any interest or any additional amounts in respect of such debt security on or after the date expressed in such debt security and to institute suit for the enforcement of any such payment.

We are required to file annually with the indenture trustee a certificate of no default, or specifying any default that exists.

Conversion Rights for Senior Debt Securities

We will set forth in the applicable prospectus supplement the terms on which senior debt securities of any series may be convertible. The subordinated indenture does not provide for conversion of the subordinated debt securities.

Events of Default

The following will be events of default under the senior indenture with respect to the senior debt securities of a series:

•

failure to pay any interest or any additional amounts on any senior debt security of that series when due, and continuance of such default for 30 days;

​

•

failure to pay principal of, or any premium on, any senior debt security of that series when due;

​

•

failure to deposit any sinking fund payment for a senior debt security of that series when due;

​

•

failure to perform any of our other covenants or warranties in the senior indenture or senior debt securities (other than a covenant or warranty included in that indenture solely for the benefit of a different series of senior debt securities), which has continued for 90 days after written notice as provided in the senior indenture;

​

12

•

acceleration of indebtedness in a principal amount in excess of  $25,000,000 for money borrowed by us, and the acceleration is not annulled, or the indebtedness is not discharged, within a specified period after written notice is given according to the senior indenture;

​

•

certain events in bankruptcy, insolvency or reorganization of us or the Bank; and

​

•

any other event of default regarding that series of senior debt securities.

​

The following will be events of default under the subordinated indenture with respect to the subordinated debt securities of a series unless such event is inapplicable to a particular series or is deleted or modified with respect to such series in the applicable resolution of our Board of Directors or supplemental indenture under which such series is issued:

•

failure to pay any interest on or any additional amounts payable with respect of any subordinated debt security of that series when due, and continuance of such default for 30 days;

​

•

failure to pay the principal of, or any premium on, any subordinated debt security of that series when due upon maturity or upon redemption, and continuance of such default for 30 days;

​

•

failure to deposit any sinking fund payment for a subordinated debt security of that series when due;

​

•

failure to perform or breach of our covenants or warranties in the subordinated indenture or the subordinated debt securities (except with respect to those covenants and warranties specifically addressed in the subordinated indenture or expressly included solely for the benefit of a series of subordinated debt securities other than such series) and continuance of such failure or breach for 90 days after notice to us of such failure or breach by Wells Fargo or the holders of at least 25% in principal amount of the outstanding debt securities of that series;

​

•

certain events in bankruptcy, insolvency or reorganization of us or the Bank; and

​

•

any other event of default regarding that series of subordinated debt securities.

​

In the event of a default in the payment of interest or principal, the holders of senior indebtedness will be entitled to be paid in full before any payment can be made to holders of subordinated debt securities. However, a holder of a subordinated debt security (or Wells Fargo or any identified trustee under the applicable subordinated indenture on behalf of all of the holders of the affected series) may, subject to certain limitations and conditions, seek to enforce overdue payments of interest or principal on the subordinated debt securities.

Subordination

The senior debt securities will be unsecured and will rank equally among themselves and with all of our unsubordinated debt or other unsecured debt, if any.

The subordinated debt securities will be unsecured and will be subordinate and junior in right of payment, to the extent and in the manner set forth below, to the prior payment in full of all of the Company’s senior indebtedness, as more fully described in the applicable prospectus supplement.

If any of the following circumstances has occurred, payment in full of all principal, premium, if any, and interest must be made or provided for with respect to all outstanding senior indebtedness before we can make any payment or distribution of principal, premium, if any, or interest on the subordinated debt securities:

•

any insolvency, bankruptcy, receivership, liquidation, reorganization or other similar proceeding relating to us or to our property has been commenced;

​

•

any voluntary liquidation, dissolution or other winding up relating to us has been commenced, whether or not such event involves our insolvency or bankruptcy;

​

13

•

any of our subordinated debt securities of any series is declared or otherwise becomes due and payable before its maturity date upon the occurrence of a specified event of default in the subordinated indenture, provided that such declaration has not been rescinded or annulled as provided in the subordinated indenture; or

​

•

any default with respect to senior indebtedness which permits its holders to accelerate the maturity of the senior indebtedness has occurred and is continuing, and either (a) notice of such default has been given to us and to the indenture trustee and judicial proceedings are commenced in respect of such default within 180 days after notice in the case of a default in the payment of principal or interest, or within 90 days after notice in the case of any other default, or (b) any judicial proceeding is pending with respect to any such default.

​

DESCRIPTION OF CAPITAL STOCK

For purposes of this section, the terms “we,” “our” and “us” refer only to First Financial and not its subsidiaries. The following summary describes the material features of our capital stock. This summary is subject to, and qualified in its entirety by reference to, our Amended and Restated Articles of Incorporation, as amended (“Articles”), and our Amended and Restated Regulations, as amended (“Regulations”), each of which is filed as an exhibit to the registration statement of which this prospectus is a part. You should refer to, and read this summary together with, our Articles and Regulations to review all of the terms of our capital stock.

Authorized Capital Stock

Our authorized capital stock consists of 160,000,000 common shares, without par value (“common shares”) and 10,000,000 preferred shares, with or without par value as determined by the Board (“preferred shares”). As of July 24, 2017, 68,730,731 of our common shares were issued, 62,142,112 of our common shares were outstanding, 6,588,619 of our common shares were held by us in treasury, and none of our preferred shares were issued or outstanding.

Common Shares

Holders of our common shares are entitled to:

•

cast one vote for each common share held of record on all matters submitted to a vote of shareholders;

​

•

receive dividends when, as and if declared by our board of directors from funds legally available therefor, subject to the rights of holders of preferred shares, if any; and

​

•

share ratably in our net assets legally available to our shareholders in the event of our liquidation, dissolution or winding up, after provision for the distribution of any preferential amounts to the holders of preferred shares, if any.

​

Holders of our common shares have no preemptive, subscription, preference, redemption, conversion, exchange or cumulative voting rights. The rights, preferences and privileges of the holders of our common shares are subject to, and may be adversely affected by, the rights, preferences and privileges of holders of any preferred shares that we may designate and issue in the future.

Subject to compliance with applicable federal and state securities laws, our common shares may be transferred without any restrictions or limitations. The transfer agent and registrar for our common shares is Registrar and Transfer Company.

Our common shares are listed on the NASDAQ Global Select Market under the symbol “FFBC”. Our outstanding common shares are, and any common shares that we issue under this prospectus and any applicable prospectus supplement will be, when issued, fully paid and nonassessable.

Preferred Shares

Our Articles authorize the Board to issue, without any further vote or action by our shareholders, subject to certain limitations prescribed by law and the rules and regulations of any stock exchange on which our securities may be listed, up to an aggregate of 10,000,000 preferred shares in one or more series.

14

Subject to the limitations described in the next paragraph, the Board is also authorized to determine and fix the powers, designations, preferences and relative, participating, optional, conversion and other special rights of each series of preferred shares issued from time to time, and the qualifications, limitations and restrictions thereof, including the designation and authorized number of each series, dividend rights, voting rights, conversion rights, redemption and exchange rights, sinking fund requirements and liquidation rights. The Board may increase or decrease the number of shares of any series of preferred shares before or after the issue of that series, but not below the number of shares of such series then outstanding. If the number of preferred shares of any series is so decreased, the shares constituting such decrease will resume the status of authorized but unissued shares. Under Ohio law, the authority of a board to establish the par value of preferred shares is not settled even if such authority is provided in the corporation’s articles. Consequently, our preferred shares will be issued without par value unless the Board determines to issue preferred shares with par value after having been advised by counsel that it has the authority to do so.

The Articles provide that the voting rights of each preferred share are limited to no more than one vote per share when voting as a class with the common shares, and the preferred shares will not vote as a separate class or series except as required by Ohio law. The Board has represented that it will not issue, without prior shareholder approval, any series of preferred shares for any defensive or anti-takeover purpose, for the purpose of implementing a shareholder rights plan, or with features specifically intended to make any attempted acquisition of the Company more difficult or costly.

The Board will fix the powers, designations, preferences and relative, participating, optional, conversion and other special rights of each series of preferred shares that we offer under this prospectus and any applicable prospectus supplement, and the qualifications, limitations and restrictions of such series, in a certificate of amendment to our Articles relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or incorporate by reference therein from another report that we file with the SEC, the form of any certificate of amendment to our Articles that describes the terms of the series of preferred shares that we are offering before the issuance of the related series of preferred shares. We will also describe in the applicable prospectus supplement the terms of the series of preferred shares being offered.

The Board may authorize the issuance of preferred shares with voting, conversion or other rights that could adversely affect the voting power or other rights of the holders of our common shares. The issuance of preferred shares could have the effect of decreasing the market price of our common shares, restricting our ability to repurchase outstanding common shares, decreasing the amount of earnings and assets available for distribution to holders of our common shares and creating restrictions upon the payment and amount of dividends and other distributions to holders of our common shares. The issuance of preferred shares also could have the effect of delaying, deterring or preventing a change in control of us without further action by our shareholders. When we issue preferred shares under this prospectus and the applicable prospectus supplement, such preferred shares will be fully paid and nonassessable.

As described below under “Description of Depositary Shares,” we may, at our option, with respect to any series of preferred shares, elect to offer fractional interests in preferred shares, and provide for the issuance of depositary receipts representing depositary shares, each of which will represent a fractional interest of a share of a particular series of preferred shares. The fractional interest will be specified in the prospectus supplement relating to a particular series of preferred shares.

The transfer agent for any series of preferred shares that we may offer under this prospectus will be named and described in the prospectus supplement for that series.

Anti-Takeover Effects of Certain Provisions of our Articles of Incorporation and Ohio Law

Our Articles contain certain provisions that make it more difficult to acquire control of us by means of a tender offer, open market purchase, a proxy fight or otherwise. These provisions are designed to encourage persons seeking to acquire control of us to negotiate with our Board. We believe that, as a general rule, the interests of our shareholders would be best served if any change in control results from negotiations with our Board. The following provisions of our Articles and Ohio law might have the effect of delaying, deterring or preventing a change in control of us and would operate only with respect to an extraordinary corporate transaction, such as a merger, reorganization, tender offer, sale or transfer of assets or liquidation involving the Company and certain persons described below.

15

The Ohio General Corporation Law provides that the approval of two-thirds of the voting power of a corporation is required to effect mergers and similar transactions, to adopt amendments to the articles of incorporation of a corporation and to take certain other significant actions. Although under Ohio law the articles of incorporation of a corporation may permit such actions to be taken by a vote that is less than two-thirds (but not less than a majority), our Articles do not contain such a provision. The two-thirds voting requirement tends to make approval of such matters, including further amendments to the Articles, relatively difficult, and a vote of the holders of in excess of one-third of our outstanding common shares would be sufficient to prevent implementation of any of the corporate actions mentioned above.

Ohio Revised Code Section 1701.831 is a “control share acquisition” statute. The control share acquisition statute basically provides that any person acquiring shares of an “issuing public corporation” (which definition we meet) in any of the following three ownership ranges must seek and obtain shareholder approval of the acquisition transaction that first puts such ownership within each such range: (i) more than 20% but less than 331∕3%; (ii) 331∕3% but not more than 50%; and (iii) more than 50%.

The purpose of the control share acquisition statute is to give shareholders of Ohio corporations a reasonable opportunity to express their views on a proposed shift in control, thereby reducing the coercion inherent in an unfriendly takeover. The provisions of the control share acquisition statute grant to our shareholders the assurance that they will have adequate time to evaluate the proposal of the acquiring person, that they will be permitted to vote on the issue of authorizing the acquiring person’s purchase in the same manner and with the same proxy information that would be available to them if a proposed merger of the Company were before them and, most importantly, that the interests of all shareholders will be taken into account in connection with such vote and the probability will be increased that they will be treated equally regarding the price to be offered for their common shares if the purchase is approved.

The control share acquisition statute applies not only to traditional offers but also to open market purchases, privately negotiated transactions and original issuances by an Ohio corporation, whether friendly or unfriendly. The procedural requirements of the control share acquisition statute could render approval of any control share acquisition difficult because it must be authorized at a special meeting of shareholders, at which a quorum is present, by the affirmative vote of the majority of the voting power represented and by a majority of the portion of such voting power, excluding interested shares. Any corporate defense against persons seeking to acquire control may have the effect of discouraging or preventing offers which some shareholders might find financially attractive. On the other hand, the need on the part of the acquiring person to convince our shareholders of the value and validity of the offer may cause such offer to be more financially attractive in order to gain shareholder approval.

Ohio Revised Code Chapter 1704 is a “merger moratorium” statute. The merger moratorium statute provides that, unless a corporation’s articles of incorporation or regulations otherwise provide, an “issuing public corporation” (which definition we meet) may not engage in a “Chapter 1704 transaction” for three years following the date on which a person acquires more than 10% of the voting power in the election of directors of the issuing corporation, unless the Chapter 1704 transaction is approved by the corporation’s board of directors prior to such transaction. A person who acquires such voting power is an “interested shareholder,” and “Chapter 1704 transactions” involve a broad range of transactions, including mergers, consolidations, combinations, liquidations, recapitalizations and other transactions between an issuing public corporation and an interested shareholder if such transactions involve 5% of the assets or shares of the issuing public corporation or 10% of its earning power. After the initial three year moratorium, Chapter 1704 prohibits such transactions absent approval by disinterested shareholders or the transaction meeting certain statutorily defined fair price provisions. One significant effect of Chapter 1704 is to encourage a person to negotiate with a corporation’s board of directors prior to becoming an interested shareholder.

Ohio also has enacted Ohio Revised Code Section 1707.043, which provides that a person who announces a control bid must disgorge profits realized by that person upon the sale of any equity securities within 18 months of the announcement.

In addition, Section 1701.59 of the Ohio Revised Code provides that, in determining what a director reasonably believes to be in the best interests of the corporation, such director may consider, in addition to the interests of the corporation’s shareholders, any of the interests of the corporation’s employees, suppliers,

16

creditors and customers, the economy of the State of Ohio and the United States, community and societal considerations and the long-term as well as the short-term interests in the corporation and its shareholders, including the possibility that these interests may be best served by the continued independence of the corporation.

The overall effect of these statutes may be to render more difficult or discourage the removal of incumbent management or the assumption of effective control by other persons.

DESCRIPTION OF DEPOSITARY SHARES

For purposes of this section, the terms “we,” “our” and “us” refer only to First Financial and not to its subsidiaries. The following description of the depositary shares representing our preferred shares sets forth certain general terms that may apply to the depositary shares that we may offer under this prospectus. The specific terms of the depositary shares and the related deposit agreement and depositary receipts will be described in the applicable prospectus supplement relating to those depositary shares. We will file forms of the applicable deposit agreement and the depositary receipts as exhibits to the registration statement of which this prospectus is a part or as exhibits to one or more reports that we file with the SEC that are incorporated by reference therein. The specific terms of the depositary shares and the related deposit agreement and depositary receipts as described in the applicable prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this prospectus.

General

We may, at our option, elect to offer fractional preferred shares, rather than full preferred shares. If we exercise this option, we will issue depositary receipts for depositary shares, each of which will represent a fractional interest of a share of a particular series of preferred shares, as specified in the applicable prospectus supplement. We will deposit with a depositary (the “preferred stock depositary”) preferred shares of each series represented by depositary shares and enter into a deposit agreement with the preferred stock depositary and holders from time to time of the depositary receipts issued by the preferred stock depositary which evidence the depositary shares. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the holder’s fractional interest in the preferred shares, to all the rights and preferences of the series of the preferred shares represented by the depositary shares (including dividend, voting, conversion, redemption and liquidation rights). The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be issued to those persons purchasing the fractional preferred shares in accordance with the terms of the deposit agreement as described in the applicable prospectus supplement.

Dividends and Other Distributions

The preferred stock depositary will distribute all cash dividends or other cash distributions received in respect of the preferred shares underlying the depositary shares to the record holders of depositary receipts in proportion to the number of the depositary receipts owned by the holders. The relevant record date for depositary shares will be the same date as the record date for the preferred shares.

In the event of a distribution other than in cash, the preferred stock depositary will distribute property received by it to the record holders of depositary receipts in proportion to the number of the depositary receipts owned by the holders. If the preferred stock depositary determines that it is not feasible to make such distribution, the preferred stock depositary may, with our approval, adopt another method for the distribution, including selling the property and distributing the net proceeds from the sale to the holders.

If we offer to the holders of a series of preferred shares represented by the depositary shares any rights, preferences or privileges to subscribe for or purchase any securities, or any other rights, preferences or privileges, the preferred stock depositary will make such rights, preferences or privileges available to the record holders of depositary shares either by the issue of warrants representing such rights, preferences or privileges or by such other method as approved by the preferred stock depositary and us. If the preferred stock depositary determines that such action is not lawful or feasible or if it is instructed by a holder that such holder does not want to exercise such rights, preferences or privileges, it may (with our approval in any

17

case when the preferred stock depositary has determined that it is not feasible to make such rights, preferences or privileges available) sell such rights, preferences or privileges and distribute the net proceeds from such sale to the holders of depositary shares entitled to such proceeds.

Withdrawal

Preferred shares represented by depositary shares may be withdrawn from the depositary arrangement upon surrender of depositary receipts at the principal office of the preferred stock depositary and upon payment of the taxes, charges and fees provided for in the deposit agreement. Subject to the terms of the deposit agreement, the holder of depositary receipts will receive the appropriate number of preferred shares and any money or property represented by such depositary shares. Only whole preferred shares may be withdrawn; if a holder holds an amount of depositary shares in excess of whole preferred shares, the preferred stock depositary will deliver along with the withdrawn preferred shares a new depositary receipt evidencing the excess number of depositary shares. Except as described in the deposit agreement, holders of withdrawn preferred shares will not be entitled to redeposit such preferred shares or to receive depositary shares for such preferred shares.

Redemption

If we redeem preferred shares held by the preferred stock depositary, the preferred stock depositary will concurrently redeem the number of depositary shares representing the preferred shares so redeemed (provided that we have paid the applicable redemption price for the preferred shares to be redeemed plus an amount equal to any accrued and unpaid dividends to the date fixed for redemption). The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable on the preferred shares multiplied by the fraction of a preferred share represented by one depositary share. If fewer than all the outstanding depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata (as nearly as may be practicable without creating fractional depositary shares) or as otherwise determined by us.

After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares will cease, except the right to receive the monies payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

Voting

Upon receipt of notice of any meeting at which the holders of the preferred shares are entitled to vote, the preferred stock depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts. Each record holder of the depositary receipts on the record date (which will be the same date as the record date for the preferred shares) will be entitled to instruct the preferred stock depositary as to the exercise of the voting rights pertaining to the amount of preferred shares represented by the holder’s depositary shares. The preferred stock depositary will vote the amount of preferred shares represented by the depositary shares in accordance with the holder’s instructions, and we will agree to take all reasonable action necessary to enable the preferred stock depositary to vote such shares. The preferred stock depositary will abstain from voting the amount of preferred shares represented by the depositary shares for which it does not receive specific instructions from the holders of depositary receipts evidencing the depositary shares.

Liquidation Preference

If we voluntarily or involuntarily liquidate, dissolve or wind up, the holders of depositary receipts will be entitled to the fraction of the liquidation preference accorded each preferred share represented by the depositary shares, as set forth in the applicable prospectus supplement.

Adjustments

Upon any change in par value or liquidation preference, split-up, combination or any other reclassification of the series of preferred shares represented by the depositary shares, or upon any

18

recapitalization, reorganization, merger or consolidation affecting us or to which we are a party, the preferred stock depositary may in its discretion, with our approval (not to be unreasonably withheld) and instructions, and in such manner as the preferred stock depositary may deem equitable, treat any securities which are received by the preferred stock depositary in exchange for or upon conversion or in respect of such preferred shares as new deposited securities received in exchange for or upon conversion or in respect of such preferred shares and may make such adjustments in the fraction of an interest represented by one depositary share in one such preferred share as may be necessary to fully reflect the effects of such change. With our approval, the preferred stock depositary may execute and deliver additional depositary receipts, or may call for the surrender of all outstanding depositary receipts to be exchanged for new depositary receipts specifically describing such new deposited securities.

Amendment

We may amend the form of depositary receipt and any provision of the deposit agreement at any time by agreement between us and the preferred stock depositary. However, any amendment that materially and adversely alters the rights of the holders of depositary receipts or that would be materially and adversely inconsistent with the rights granted to the holders of the related preferred shares will not be effective unless the holders of at least two-thirds of the depositary shares evidenced by the depositary receipts then outstanding approve the amendment. No amendment will impair the right, subject to the exceptions set forth in the deposit agreement, of any holder of depositary receipts to surrender any depositary receipt with instructions to deliver to the holder the related preferred shares and all money and other property, if any, represented by the depositary receipt, except in order to comply with law. Every holder of an outstanding depositary receipt at the time any such amendment becomes effective will be deemed, by continuing to hold the receipt, to consent and agree to the amendment and to be bound by the deposit agreement as amended.

Termination

We may terminate the deposit agreement upon not less than 30 days’ prior written notice to the preferred stock depositary if a majority of each series of preferred shares affected by the termination consents to the termination. Upon termination, the preferred stock depositary will deliver or make available to each holder of depositary receipts, upon surrender of the depositary receipts held by the holder, the number of whole and/or fractional preferred shares represented by the depositary shares evidenced by the depositary receipts together with any other property held by the preferred stock depositary with respect to the depositary receipt.

In addition, the deposit agreement will automatically terminate if:

•

all outstanding depositary shares have been redeemed;

​

•

there has been a final distribution in respect of the related preferred shares in connection with our liquidation, dissolution or winding up and the distribution has been made to the holders of depositary receipts evidencing the depositary shares representing the preferred shares; or

​

•

each related preferred share has been converted into our common shares or other securities which are not represented by depositary shares.

​

Charges of Preferred Stock Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the deposit agreement. In addition, we will pay the fees and charges of the preferred stock depositary in connection with the initial deposit of the preferred shares, the initial issuance of the depositary shares, any redemption of the preferred shares and all withdrawals of preferred shares by owners of depositary shares. All other transfer, income and other taxes and governmental charges will be at the expense of the holders of depositary receipts. Holders of depositary receipts will also pay such other charges and expenses (i) as are expressly provided in the deposit agreement to be for their accounts and (ii) for any duties requested by the holders to be performed which are outside of those expressly provided for in the deposit agreement. If those charges, expenses and taxes have not been paid by the holders of depositary receipts, the preferred stock depositary may refuse to transfer depositary shares or withdraw any preferred shares, withhold dividends and distributions and sell the preferred shares or other property represented by the depositary shares evidenced by the depositary receipts.

19

Resignation and Removal of Preferred Stock Depositary

The preferred stock depositary may resign at any time by delivering to us notice of its election to resign, and we may at any time remove the preferred stock depositary. Any such resignation or removal will take effect upon our appointment of a successor preferred stock depositary and its acceptance of such appointment. We must appoint a successor preferred stock depositary within 60 days after delivery of the notice of resignation or removal, and any preferred stock depositary must be a bank or trust company having its principal office in the United States and having the requisite combined capital and surplus as set forth in the applicable agreement.

Notices

The preferred stock depositary will forward to holders of depositary receipts any notice, reports and other communications that are delivered to the depositary and that we are required to furnish to the holders of the preferred shares. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred shares.

Limitation of Liability

We will not be liable, nor will the preferred stock depositary be liable, if we or the preferred stock depositary are prevented from or delayed, by law or any circumstances beyond our control, in performing our respective obligations under the deposit agreement. Our obligations and the obligations of the preferred stock depositary under the deposit agreement will be limited to performing our duties in good faith and without negligence (only in the case of any action or inaction in the voting of preferred shares represented by the depositary shares), gross negligence or willful misconduct. We will not be obligated, nor will the preferred stock depositary be obligated, to prosecute or defend any legal proceeding in respect of any depositary receipts, depositary shares or preferred shares represented by depositary shares unless satisfactory indemnity is furnished. We may rely, and the preferred stock depositary may rely, on written advice of counsel or accountants, or information provided by holders of depositary receipts or other persons believed in good faith to be competent to give such information, and on documents reasonably believed to be genuine and signed or presented by a proper party.

DESCRIPTION OF WARRANTS

For purposes of this section, the terms “we,” “our” and “us” refer only to First Financial and not to its subsidiaries. The following description of the warrants sets forth general terms that may apply to the warrants that we may offer under this prospectus. The specific terms of any series of warrants and the related warrant agreement (including the form of the warrant certificate) will be described in the applicable prospectus supplement relating to those warrants. We will file the form of the applicable warrant agreement (including the form of the warrant certificate) as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to one or more reports that we file with the SEC that are incorporated by reference therein. The specific terms of any series of warrants and the related warrant agreement (including the form of the warrant certificate) as described in the applicable prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this prospectus.

We may issue warrants in one or more series to purchase debt securities, common shares, preferred shares, depositary shares or units of two or more of those securities. We may issue warrants independently or together with any other securities we offer pursuant to a prospectus supplement, and the warrants may be attached to or separate from such securities. We will issue each series of warrants under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or on behalf of holders or beneficial owners of warrants.

The applicable prospectus supplement will describe the terms of any warrants being offered and the applicable warrant agreement (including the form of the warrant certificate), including the following, as may be applicable: the title of the warrants; the total number of warrants to be issued and currently outstanding, if any; the consideration for which we will issue the warrants, including the applicable currency or currencies; anti-dilution provisions to adjust the number of our common shares or other securities to be delivered upon exercise of the warrants; the designation, number or amount and terms of the underlying securities issuable upon exercise of the warrants; the price at which and the currency or currencies in which investors may purchase the underlying securities purchasable upon exercise of the warrants, and any provisions for changes to or adjustments in the price; the dates on which the right to exercise the warrants will commence and expire; the procedures and conditions relating to the exercise of the warrants; whether the warrants will be in registered or bearer form; information with respect to book-entry registration and transfer procedures, if any; the minimum or maximum amount of warrants which may be exercised at any one time; the designation and terms of the related securities with which the warrants are issued and the number of warrants issued with each such security; the date, if any, on and after which the warrants and securities issued with the warrants will be separately transferable; a discussion of material United States federal income tax considerations; the identity of the warrant agent; and any other terms of the warrants, including terms, procedures, conditions and limitations relating to the exchange, transfer, redemption and exercise of the warrants.

Prior to the exercise of their warrants, holders of warrants exercisable for debt securities will not have any of the rights of holders of the debt securities purchasable upon such exercise and will not be entitled to payments of principal (or premium, if any) or interest, if any, on the debt securities purchasable upon such exercise, or to enforce covenants in the applicable indenture. Prior to the exercise of their warrants, holders of warrants exercisable for our common shares, preferred shares or depositary shares will not have any rights of holders of common shares, preferred shares or depositary shares purchasable upon such exercise, including any rights to vote such shares or to receive any distributions or dividends thereon.

Exercise of Warrants

A warrant will entitle the holder to purchase the securities at the exercise price set forth in, or that will be determinable as described in, the applicable prospectus supplement. Warrants may be exercised at any time prior to the close of business on the expiration date, and in accordance with the procedures, set forth in the applicable prospectus supplement. Upon and after the close of business on the expiration date, unexercised warrants will be void and have no further force, effect or value.

Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchased upon such exercise. If less than all of the

21

warrants represented by the warrant certificate are exercised, we will issue a new warrant certificate for the remaining warrants. Warrant certificates may be exchanged for new warrant certificates of different denominations, and warrants may be exercised at the warrant agent’s corporate trust office or any other office indicated in the applicable prospectus supplement.

Enforceability of Rights; Governing Law

The holders of warrants, without the consent of the warrant agent, may, on their own behalf and for their own benefit, enforce, and may institute and maintain any suit, action or proceeding against us to enforce, their rights to exercise and receive the securities purchasable upon exercise of their warrants. Unless otherwise stated in the applicable prospectus supplement, each issue of warrants and the applicable warrant agreement will be governed by the laws of the State of Ohio.

DESCRIPTION OF RIGHTS

For purpose of this section, the terms “we,” “our” and “us” refer only to First Financial and not to its subsidiaries. The following description of the rights sets forth certain general terms that may apply to the rights that we may offer under this prospectus. The specific terms of any rights and the related rights agreement (including the form of rights certificate) will be described in the applicable prospectus supplement relating to those rights. We will file the form of the applicable rights agreement (including the form of rights certificate) as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to one or more reports that we file with the SEC that are incorporated by reference therein. The specific terms of any rights and the related rights agreement (including the form of rights certificate) as described in the applicable prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this prospectus.

We may issue rights to purchase debt securities, common shares, preferred shares or depositary shares that we may offer to our securityholders. The rights may be issued independently or together with any other securities we offer, and may or may not be transferable by the persons purchasing or receiving the rights. In connection with any rights offering, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons may be required to purchase any offered securities remaining unsubscribed for after such rights offering. Each series of rights will be issued under a separate rights agreement which we will enter into with a bank or trust company, as rights agent, that we will name in the applicable prospectus supplement. The rights agent will act solely as our agent in connection with the certificates representing the rights and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights.

The applicable prospectus supplement will describe the terms of any rights being offered and the applicable rights agreement (including the form of the rights certificate), including the following, as may be applicable: the date of determining the securityholders entitled to participate in the rights offering; the consideration for which we will issue the rights; the total number of rights to be issued; the designation, number or amount and terms of the underlying securities issuable upon exercise of the rights; the price at which and the currency or currencies in which investors may purchase the underlying securities purchasable upon exercise of rights, and any provisions for changes to or adjustments in the price; the dates on which the holder’s ability to exercise the rights will commence and expire; the procedures and conditions relating to the exercise of the rights; the extent to which the rights will be transferable; the extent to which the rights may include an over-subscription privilege with respect to unsubscribed securities; the material terms of any standby underwriting or purchase agreement entered into by us in connection with the rights offering; a discussion of material United States federal income tax considerations applicable to the exercise of the rights; the identity of the rights agent; and any other terms of the rights, including terms, procedures, conditions and limitations relating to the distribution, exchange and exercise of the rights.

Exercise Price

Each right will entitle its holder to purchase the underlying securities at the exercise price set forth in the applicable prospectus supplement. Our Board will determine the exercise price or prices for the rights based upon a number of factors, including, without limitation: our business prospects; our capital

22

requirements; the price or prices at which an underwriter or standby purchasers may be willing to purchase securities that remain unsold in the rights offering; and general conditions in the securities markets, especially for securities of financial institutions. The subscription price may or may not reflect the actual or long-term fair value of the securities offered in the rights offering. We provide no assurances as to the market values or liquidity of any rights issued, or as to whether or not the market prices of the securities subject to the rights will be more or less than the rights’ exercise price during the term of the rights or after the rights expire.

Exercising Rights

The manner of exercising rights will be set forth in the applicable prospectus supplement. Upon receipt of payment and the rights certificate properly completed and duly executed at the corporate trust office of the rights agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchased upon such exercise. If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than our securityholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

Expiration of Rights

The applicable prospectus supplement will set forth the expiration date and time for exercising rights. If holders of rights do not exercise their rights prior to such time, their rights will expire and will no longer be exercisable and will become void and have no value. We will extend the expiration date as required by applicable law and may, in our sole discretion, extend the expiration date. If we elect to extend the expiration date, we will issue a press release announcing such extension prior to the scheduled expiration date.

Fees and Expenses

We will pay all fees charged by the rights agent in connection with the distribution and exercise of rights. Rights holders will be responsible for paying all other commissions, fees, taxes or other expenses incurred in connection with their transfer of rights that are transferable. Neither we nor the rights agent will pay such expenses.

Withdrawal and Termination

We may withdraw the rights offering at any time prior to the Expiration Date for any reason. We may terminate the rights offering, in whole or in part, at any time before completion of the rights offering if there is any judgment, order, decree, injunction, statute, law or regulation entered, enacted, amended or held to be applicable to the rights offering that in the sole judgment of our Board would or might make the rights offering or its completion, whether in whole or in part, illegal or otherwise restrict or prohibit completion of the rights offering. We may waive any of these conditions and choose to proceed with the rights offering even if one or more of these events occur. If we terminate the rights offering, in whole or in part, all affected rights will expire without value, and all subscription payments received by the subscription agent will be returned promptly without interest.

DESCRIPTION OF STOCK PURCHASE CONTRACTS

For purpose of this section, the terms “we,” “our” and “us” refer only to First Financial and not to its subsidiaries. The following description of stock purchase contracts sets forth certain general terms that may apply to the stock purchase contracts that we may offer under this prospectus. The specific terms of any stock purchase contracts will be described in the applicable prospectus supplement relating to the stock purchase contracts. We will file forms of the relevant documents as exhibits to the registration statement of which this prospectus is a part or as exhibits to one or more reports that we file with the SEC that are incorporated by reference therein. The specific terms of any stock purchase contracts as described in the applicable prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this prospectus.

23

We may issue stock purchase contracts representing contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified number of common shares, preferred shares or depositary shares at a future date or dates. The price per common share, preferred share or depositary share may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. Any purchase contract may include anti-dilution provisions to adjust the number of shares issuable pursuant to such purchase contract upon the occurrence of certain events.

DESCRIPTION OF UNITS

For purpose of this section, the terms “we,” “our” and “us” refer only to First Financial and not to its subsidiaries. We may issue units consisting of one or more debt securities, common shares, preferred shares, depositary shares, warrants, rights, stock purchase contracts or any combination of such securities. The applicable prospectus supplement will describe the terms of any units being offered and the applicable unit agreement (including the form of unit), including the following, as may be applicable: the terms of the units and of the debt securities, common shares, preferred shares, depositary shares, warrants, rights, stock purchase contracts or any combination of such securities comprising the units, including whether and under what circumstances the securities comprising the units may be traded separately; a discussion of material United States federal income tax considerations applicable to the units; and the provisions for the payment, settlement, transfer or exchange or the units.

PLAN OF DISTRIBUTION

We may sell the securities offered under this prospectus from time to time:

•

to or through underwriters;

​

•

to or through dealers;

​

•

through agents;

​

•

directly to purchasers;

​

•

in “at the market offerings” within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market, on an exchange, or otherwise;

​

•

through a dividend, distribution, rights offering, forward contracts or similar arrangements;

​

•

through a combination of any of these methods of sale; or

​

•

through any other methods described in the applicable prospectus supplement.

​

The securities we distribute by any of these methods may be sold, in one or more transactions:

•

at a fixed price or prices, which may be changed;

​

•

at market prices prevailing at the time of sale;

​

•

at prices related to prevailing market prices; or

​

•

at negotiated prices.

​

Each time we offer securities under this prospectus, the applicable prospectus supplement will describe the specific plan of distribution and the terms of the offering of the securities, including:

•

the name or names of any underwriters, dealers or agents;

​

•

the purchase price of the securities and the proceeds we will receive from the sale;

​

•

any over-allotment options under which underwriters may purchase additional securities from us;

​

•

any discounts, concessions, commissions, agency fees and other items constituting underwriters’, dealers’ or agents’ compensation;

​

•

any initial public offering price;

​

24

•

any delayed delivery arrangements;

​

•

any discounts or concessions allowed or reallowed or paid to dealers; and

​

•

any securities exchange on which the securities may be listed.

​

We may sell securities from time to time to one or more underwriters, who would purchase the securities as principal for resale to the public, either on a firm-commitment or best-efforts basis. If we sell securities to underwriters, we will execute an underwriting agreement with the underwriters at the time of sale, and we will name the underwriters in the applicable prospectus supplement. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. The underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. The underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

In connection with sales to underwriters, the underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agents. Underwriters may resell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from purchasers for whom they may act as agents. The applicable prospectus supplement will include any required information about underwriting compensation we pay to underwriters, and any discounts, concessions or commissions underwriters allow to participating dealers, in connection with an offering of securities.

From time to time, we may sell securities to one or more dealers acting as principals. The dealers, who may be deemed to be underwriters within the meaning of the Securities Act, may then resell those securities to the public. The applicable prospectus supplement will include the names of the dealers and the terms of the transaction.

We may solicit offers to purchase securities directly from the public from time to time. In this case, no underwriters or agents would be involved. We may also designate agents from time to time to solicit offers to purchase securities from the public on our behalf. Such agents may be deemed to be underwriters within the meaning of the Securities Act. The applicable prospectus supplement relating to any particular offering of securities will name any agents designated to solicit offers and will include information about any compensation we may pay the agents in connection with that offering. Unless otherwise indicated in the applicable prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others. These persons may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such direct sales will be described in the applicable prospectus supplement.

We may make direct sales of the securities through subscription rights distributed to our existing securityholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or we may engage the services of one or more underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities to third parties. The terms of any such sales or arrangements will be described in the applicable prospectus supplement.

We may authorize underwriters, dealers and agents to solicit from certain types of institutional investors offers to purchase securities under delayed delivery contracts providing for payment and delivery on future dates. The applicable prospectus supplement will describe the material terms of these contracts, including any conditions to the purchasers’ obligations, and will include any required information about commissions we may pay for soliciting these contracts.

25

We may authorize one or more “remarketing firms” to sell securities pursuant to a remarketing arrangement upon the purchase of the securities. Remarketing firms will act as principals for their own accounts or as agents for us, and will offer or sell the securities in accordance with a redemption or repayment pursuant to the terms of the securities, or otherwise. The applicable prospectus supplement will identify any remarketing firm and describe the terms of its compensation and agreements, if any, with us. Remarketing firms may be deemed to be underwriters within the meaning of the Securities Act with respect to the securities they remarket.

Unless the applicable prospectus supplement states otherwise, the securities offered under this prospectus (other than our common shares) will be a new issue of securities with no established trading market. We may elect to list any series of offered securities on an exchange. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriters that we use in the sale of offered securities may engage in over-allotment, stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions involve bids to purchase the underlying securities in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution has been completed, in order to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover short positions. These activities may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

Any underwriters, dealers or agents participating in the distribution of the offered securities may be deemed to be underwriters under the Securities Act, and any compensation and profits received by such persons upon sale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters, dealers, agents and other persons may be entitled, under agreements that they may enter into with us, to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments that such persons make with respect to these liabilities. Our underwriters, dealers and agents, or their affiliates, may be customers of, engage in transactions with, or perform services for, us in the ordinary course of business.

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities being offered under this prospectus will be passed upon for us by Vorys, Sater, Seymour and Pease LLP, Cincinnati, Ohio. Unless otherwise provided in the applicable prospectus supplement, certain legal matters will be passed upon for any underwriter or agents by their own legal counsel.

PART II.   INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14.   Other Expenses of Issuance and Distribution

The following is an itemized statement of the estimated fees and expenses in connection with the issuance and distribution of the securities registered hereby:

(1)

The Company is registering an indeterminate amount of securities under this Registration Statement and in accordance with Rules 456(b) and 457(r), the Company is deferring payment of any registration fee until the time the securities are offered under this Registration Statement pursuant to a prospectus supplement.

​

(2)

These fees and expenses are calculated based on the number of issuances and amount of securities offered and, accordingly, cannot be estimated at this time.

​

Item 15.   Indemnification of Directors and Officers

Under Section 1701.13(E) of the Ohio General Corporation Law (the “OGCL”), directors, officers, employees and agents of an Ohio corporation have an absolute right to indemnification for expenses (including attorneys’ fees) actually and reasonably incurred by them in any action, suit or proceeding to the extent they are successful, on the merits or otherwise, in defense of the action, suit or proceeding, including derivative actions, brought against them, or in defense of any claim, issue or matter asserted in any such proceeding.

Section 1701.13(E) of the OGCL permits a corporation to indemnify its directors, officers, employees or agents or individuals who are or were serving at the request of the corporation as a director, trustee, officer, employee, member, manager or agent of another corporation or entity in circumstances where indemnification is not mandated by the statute if certain statutory standards are satisfied. A corporation may grant indemnification in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, investigative or administrative, other than derivative actions, if the indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Such indemnification is permitted against expenses (including attorneys’ fees) as well as judgments, fines and amounts paid in settlement actually and reasonably incurred by the indemnitee in connection with the action, suit or proceeding.

Under Section 1701.13(E), a corporation may also provide indemnification in derivative actions for expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of an action or suit if the officer, director, employee or agent acted in good faith and in a manner such person reasonably believed to be in, or not opposed to, the best interests of the corporation. Ohio law does not expressly authorize indemnification against judgments, fines and amounts paid in settlement of derivative actions. A corporation may not indemnify a director, officer, employee or agent in derivative actions for expenses (including attorneys’ fees) if such person is adjudged to be liable for negligence or misconduct in the performance of such person’s duties to the corporation, unless and only to the extent that a court determines that, despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity as the court deems proper. In addition, a corporation may not indemnify a director in any action or suit in which the only liability asserted against the director is for approving unlawful loans, dividends or distributions of assets under Section 1701.95 of the OGCL.

II-1

Section 1701.13(E) of the OGCL permits a corporation to pay expenses (including attorneys’ fees) incurred by a director, officer, employee or agent as they are incurred, in advance of the final disposition of the action, suit or proceeding, as authorized by the corporation’s directors and upon receipt of an undertaking by such person to repay such amount if it is ultimately determined that such person is not entitled to indemnification.

Section 1701.13(E) of the OGCL states that the indemnification provided thereby is not exclusive of, and is in addition to, any other rights granted to persons seeking indemnification under a corporation’s articles or regulations, any agreement, a vote of the corporation’s shareholders or disinterested directors, or otherwise. In addition, Section 1701.13(E) of the OGCL grants express power to a corporation to purchase and maintain insurance or furnish similar protection, including trust funds, letters of credit and self-insurance, for director, officer, employee or agent liability, regardless of whether that individual is otherwise eligible for indemnification by the corporation.

The foregoing discussion is necessarily subject to the complete text of Section 1701.13(E), which provides for indemnification of directors, officers and other parties in certain circumstances, and is qualified in its entirety by reference thereto.

Article SIXTH of the Amended and Restated Articles of Incorporation of the Company, as amended, provides that each person who is or was a director, officer, employee or agent of the Company shall be indemnified by the Company to the full extent permitted by the Ohio Revised Code against any liability, cost or expense incurred by such person in such capacity, or arising out of such person’s status as a director, officer, employee or agent of the Company. Article IV of the Amended and Restated Regulations of the Company, as amended, provides that the Company shall, to the full extent permitted by the OGCL, indemnify all persons whom it may indemnify.

The Company maintains insurance policies under which directors and officers of the Company and its subsidiaries are insured, within the limits and subject to the limitations of such policies, against expenses in connection with the defense of actions, suits or proceedings, and certain liabilities that might be imposed as a result of such actions, suits or proceedings, to which they are parties by reason of being or having been directors or officers of the Company or its subsidiaries.

Item 16.   Exhibits

The exhibits filed (unless otherwise noted) as a part of this Registration Statement are set forth in the accompanying Exhibit Index.

Item 17.   Undertakings

(a)

The undersigned registrant hereby undertakes:

​

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

​

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

​

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

​

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

​

II-2

Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

​

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

​

(4)

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

​

Each prospectus filed by a registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

​

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

​

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

​

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

​

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about an undersigned registrant or its securities provided by or on behalf of an undersigned registrant; and

​

II-3

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

​

(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

​

(c)

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by a registrant of expenses incurred or paid by a director, officer or controlling person of a registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, that registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

​

(d)

The undersigned registrant hereby undertakes that:

​

(i)

For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

​

(ii)

For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

​

(e)

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.
