On September 21, 2009, First Financial Bancorp announced that it would hold a conference call regarding its recent FDIC-assisted transactions completed on September 18, 2009 whereby First Financial Bank acquired certain assets and acquired certain liabilities of Irwin Union Bank and Trust Company, Columbus, Indiana and Irwin Union Bank, F.S.B., Louisville, Kentucky.

Certain statements in this Form 8-K are forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 (the "Exchange Act"). These statements are based on management's current expectations or predictions of future results or events. We make these forward-looking statements in reliance on the safe harbor provisions provided under the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical fact, included in this report which relate to performance, development or activities that we expect or anticipate will or may happen in the future, are forward looking statements.

Forward-looking statements involve inherent risks and uncertainties and are based on numerous assumptions. They are not guarantees of future performance. A number of important factors could cause actual results to differ materially from those in the forward-looking statement including events and conditions related to the closing of the transaction described in this Report and in the Exhibits. Forward-looking statements contained herein are made only as of the date made, and we do not undertake any obligation to update them to reflect events or circumstances after the date of this report to reflect the occurrence of unanticipated events.

Because forward-looking statements involve risks and uncertainties, we caution that there are important factors, in addition to those listed above, that may cause actual results to differ materially from those contained in the forward-looking statements. These factors are included in our Form 10-Q for the period ended June 30, 2009, as filed with the Securities and Exchange Commission.
