Item 8.01Other Events.

On March 14, 2012, First Financial Bancorp. (the Company) notified the warrant agent, Registrar & Transfer Company, as well as The Depository Trust Company, of an adjustment to the exercise price of warrants to purchase shares of the Company's common stock expiring December 23, 2018 (the Warrants) pursuant to the Warrant Agreement (the Agreement), dated as of June 2, 2010, between the Company and Registrar and Transfer Company and to the form of Warrant Certificate included as Exhibit A to the Agreement (the Certificate). Capitalized terms used but not defined herein have the meanings ascribed to them in the Agreement or the Certificate.

On January 29, 2013, the Company's Board of Directors declared a quarterly dividend of $0.28 per share of Common Stock, payable on April 1, 2013, to shareholders of record at the close of business on March 1, 2013.

These dividends trigger a requirement under Section 12 of the Certificate for adjustments to the Exercise Price and the Warrant Share Number. Accordingly, the Company gave notice to Warrant holders that, effective at the close of business on March 14, 2013, the Exercise Price had been adjusted from $12.343 to $12.255.

No adjustment was made to the Warrant Share Number, because the cumulative amount of such adjustments to date (before giving effect to the minimum adjustment threshold or rounding as specified in Section 12(E) of the Certificate) would have been an increase to approximately 1.0526 shares, representing an increase of less than one-tenth (1/10th) of a share. In accordance with Section 12(E), this amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate 1/10th of a share of Common Stock, or more, or on exercise of a Warrant if it shall earlier occur.
