Fifth Third requests that shareholders of Fifth Third entitled to vote at the special meeting vote by telephone, over the Internet or by completing and signing the accompanying proxy card and returning it to Fifth Third as soon as possible in the enclosed postage-paid envelope. When the accompanying proxy card is returned properly executed, the shares of Fifth Third common stock represented by it will be voted at the Fifth Third special meeting in accordance with the instructions contained on the proxy card. If you make no specification on your proxy card as to how you want your shares voted before signing and returning it, your proxy will be voted “FOR” the Fifth Third stock issuance proposal and “FOR” the Fifth Third adjournment proposal. If a holder’s shares are held in “street name” by a broker, bank or other nominee, the holders should check the voting form used by that firm to determine whether the holder may vote by telephone or the Internet. Every vote is important. Accordingly, you should sign, date and return the enclosed proxy card, or vote via the Internet or by telephone, whether or not you plan to attend the Fifth Third special meeting virtually. Sending in your proxy card or voting by telephone or on the Internet will not prevent you from voting your shares personally at the meeting because you may revoke your proxy at any time before it is voted.
