* Forward Looking Statements This presentation may contain, and during this presentation our management may make, statements that may constitute “forward-looking statements” within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are not historical facts but instead represent only our beliefs regarding future events or outcomes, many of which, by their nature, are inherently uncertain and outside our control. Forward-looking statements include, among other things, statements regarding our future anticipated financial performance, business prospects, future growth and operating strategies, objectives and results. Actual results, performance or developments could differ materially from those expressed or implied by these forward-looking statements. Important factors that could cause actual results to differ from those in the forward-looking statements include, among others, those discussed in our Annual Report on Form 10-K and other reports filed with the Securities and Exchange Commission, copies of which will be made available upon request.

Non-GAAP Disclaimer This presentation contains GAAP financial measures and, where management believes it to be helpful in understanding the Company’s results of operations or financial position, non-GAAP financial measures. Where non-GAAP financial measures are used, the most directly comparable GAAP financial measure, as well as the reconciliation to the most directly comparable GAAP financial measure can be found in the Company’s current quarter earnings release or Quarterly Report on Form 10-Q which can be found on the Company’s website at www.firstmidwest.com/secfilings. Non-GAAP financial measures in this presentation include core operating earnings and pre-tax, pre-provision return on risk weighted average assets. Both of these measures are useful in understanding the performance and trends of the Company’s core franchise over time without respect to investment securities gains/losses, taxes, provisions expense and OREO losses, each of which can significantly vary from quarter to quarter, and therefore may distort the Company’s underlying performance.
