This Current Report may contain forward-looking statements regarding the financial performance, business prospects, growth and operating strategies of Horizon and LaPorte Bancorp. For these statements, Horizon and LaPorte Bancorp claim the protections of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Statements in this press release should be considered in conjunction with the other information available about Horizon and LaPorte Bancorp, including the information in the filings each makes with the Securities and Exchange Commission. Forward-looking statements provide current expectations or forecasts of future events and are not guarantees of future performance. The forward-looking statements are based on management’s expectations and are subject to a number of risks and uncertainties. Horizon and LaPorte Bancorp have tried, wherever possible, to identify such statements by using words such as “anticipate,” “estimate,” “project,” “intend,” “plan,” “believe,” “will” and similar expressions in connection with any discussion of future operating or financial performance.

Although Horizon’s and LaPorte Bancorp’s management believe that the expectations reflected in such forward-looking statements are reasonable, actual results may differ materially from those expressed or implied in such statements.
