        <footnote id="F1">Pursuant to the Fifth Third Bancorp Stock Option Gain Deferral Plan, Mr. Schaefer elected to defer receipt of 153,091 shares of common stock issuable upon exercise of his option. As a result, 153,091 shares of phantom stock have accrued to his Deferred Stock Unit Account under the Plan. Because these phantom stock units may only be settled by a one-for-one delivery of shares of common stock upon expiration of the deferral period, Mr. Schaefer is currently deemed to be the direct beneficial owner of these shares which are included in his aggregate beneficial ownership on Table I.</footnote>
