        <footnote id="F1">Due to an error in the calculation of common shares directly held by the reporting person, the Form 4 filed on 4/3/2018 incorrectly stated the number of common shares of FFBC stock acquired by the reporting person as a result of the merger of First Financial Bancorp and MainSource Financial Group which closed on 4/1/2018.  The number of shares was originally reported as 87,259, and should have been reported as 77,960.</footnote>
        <footnote id="F2">Received pursuant to the merger agreement between First Financial Bancorp. (&quot;First Financial&quot;) and MainSource Financial Group, Inc. (&quot;MainSource&quot;), dated July 25, 2017 (the &quot;Merger Agreement&quot;), pursuant to which MainSource was merged with and into First Financial on April 1, 2018 (the &quot;Effective Time&quot;). Pursuant to the Merger Agreement, as of the Effective Time, (i) each issued and outstanding share of MainSource's common stock converted into the right to receive 1.3875 shares of First Financial common stock and cash in lieu of fractional shares (the &quot;Merger Consideration&quot;), and (ii) each outstanding restricted share and each outstanding performance share unit fully vested and was cancelled and converted automatically into the right to receive the Merger Consideration in respect of each share of MainSource's common stock underlying such award, less applicable tax withholdings. On the trading day immediately preceding Effective Date, the closing price of MainSource's common stock was $40.65 per share and the closing price of First Financial's common stock was $29.35 per share.</footnote>
        <footnote id="F3">Form 4 filed on 4/3/2018 included incorrect information in the footnote related to this acquisition of shares.  The footnote has been updated to reflect the correct information related to the acquisition.</footnote>
        <footnote id="F4">Received in the Merger in exchange for an employee stock option to acquire 10,287 shares of MainSource common stock for $16.08 per share.</footnote>
