measure of the registrant's historical or future financial performance, financial position or cash flows that excludes amounts, or
is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure
calculated and presented in accordance with GAAP in the statement of income, balance sheet or statement of cash flows (or
equivalent statements) of the issuer; or includes amounts, or is
subject to adjustments that have the effect of including
amounts, that are excluded from the most directly comparable measure so calculated and presented.   In this regard, GAAP
refers to generally accepted accounting principles in the United
States.  Pursuant to the requirements of Regulation G, Old
National Bancorp has provided reconciliations within the slides,
as necessary, of the non-GAAP financial measure to the most
directly comparable GAAP financial measure.
