Such acquisitions will not be registered under the Securities Act or any state securities laws; however, persons that acquire shares from us pursuant to such acquisitions may, with our written consent, use this prospectus to resell such shares of our common stock. Sales by such persons may be made in a number of ways, including, without limitation: o through the New York Stock Exchange, in the over-the-counter market, in privately negotiated transactions or otherwise; o directly to purchasers or through agents, brokers, dealers or underwriters; and o at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. Selling shareholders may effect such transactions by selling the shares to or through broker-dealers or underwriters. These broker-dealers, if used, may receive discounts, concessions or commissions from the selling shareholders or from the purchaser of the shares. The selling shareholders will receive the purchase price of the shares of stock sold less any such discounts, concessions or commissions. The selling shareholders will be responsible for any such discounts, concessions or commissions. We will not receive any proceeds from the sale of the shares by the selling shareholders. We will furnish this prospectus to the security holders of the companies that we intend to acquire prior to the completion of the acquisition.

OLD NATIONAL BANCORP We are a bank holding company that operates 133 banking offices and 252 ATM locations in Indiana, Illinois and Kentucky through our bank subsidiaries. These banks provide a wide range of financial services, including: o commercial, consumer and real estate loans; o deposit products; o issuing and servicing credit cards; o leasing; o letters of credit; and o safe deposit facilities. We also own nonbank subsidiaries which provide additional financial services incidental to its operations, including: o securities brokerage services; o fiduciary and trust services; o investment services; and o issuance and reinsurance of credit life, accident, health, life, property and casualty insurance. We were incorporated in 1982 in the State of Indiana as the holding company of Old National Bank in Evansville, Indiana. Old National Bank has provided banking services since 1834. We began an acquisition program in 1985 and have acquired 38 financial institutions since that time. We continue to explore opportunities to acquire banks, savings associations and non-bank companies and are currently reviewing and analyzing potential acquisitions, as well as engaging in discussions or negotiations concerning potential acquisitions. There can be no assurance that any of these discussions or negotiations will result in definitive agreements or consummated acquisitions. 3 As a legal entity separate and distinct from its bank and non-bank subsidiaries, our principal sources of revenues are dividends and fees from its bank and non-bank subsidiaries. The subsidiaries that operate in the banking, insurance and securities business can pay dividends only if they are in compliance with the applicable regulatory requirements imposed on them by federal and state regulatory authorities. REGULATORY MATTERS As a bank holding company, we are subject to regulation, supervision and examination by the Board of Governors of the Federal Reserve System under the Bank Holding Company Act of 1956, as amended. For a discussion of certain material elements of the regulatory framework applicable to bank holding companies and their subsidiaries and certain specific information relevant to us, see our annual report on Form 10-K for the fiscal year ended December 31, 2002 which is incorporated by reference into this prospectus. This regulatory framework is intended primarily for the protection of depositors and the federal deposit insurance funds and not for the protection of security holders or creditors. The various government rules, regulations and requirements that apply to us impact our business and activities. A change in applicable statutes, rules, regulations and requirements that apply to us impact business and activities may have a material effect on our business and earnings. In addition, our business and earnings are affected by general economic conditions, legislation and actions of regulatory authorities. Under policy of the Federal Reserve, a bank holding company is expected to act as a source of financial strength for its bank subsidiaries and to commit resources to support such banks. As a result, the Federal Reserve may require us to commit resources to our bank subsidiaries. USE OF PROCEEDS We will not receive any of the proceeds from the sale of the shares of our common stock offered hereby. All proceeds from the sale of such shares of our common stock will be received by the selling shareholders, as described below. See "Selling Shareholders" and "Plan of Distribution." SELLING SHAREHOLDERS This prospectus relates to the offer for sale or other distribution of shares of our common stock by persons who will acquire shares of our common stock in connection with our acquisition of businesses. Such selling shareholders will be identified from time to time by supplements to this prospectus. PLAN OF DISTRIBUTION The shares may be sold or distributed from time to time by the selling shareholders to be named in a prospectus supplement, by their permitted donees or transferees, or by their other successors in interest. The selling shareholders may sell their shares at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. Each selling shareholder may reserve the right to accept or reject, in whole or in part, any proposed purchase of shares, whether the purchase is to be made directly or through agents. 4 The selling shareholders may offer their shares at various times in one or more of the following transactions: o in ordinary brokers' transactions and transactions in which the broker solicits purchasers; o in transactions involving cross or block trades or otherwise on The New York Stock Exchange; o in transactions in which brokers, dealers or underwriters purchase the shares as principal and resell the shares for their own accounts pursuant to this prospectus; o in transactions "at the market" to or through market makers in the common stock or into an existing market for our common stock; o in other ways not involving market makers or established trading markets, including direct sales of the shares to purchasers or sales of the shares effected through agents; o through transactions in options, swaps or other derivatives which may or may not be listed on an exchange; o in privately negotiated transactions; or o in a combination of any of the foregoing transactions. The selling shareholders also may sell their shares in accordance with Rule 144 under the Securities Act. From time to time, one or more of the selling shareholders may pledge or grant a security interest in some or all of the shares owned by them. If the selling shareholders default in performance of the secured obligations, the pledgees or secured parties may offer and sell the shares from time to time. The selling shareholders also may transfer and donate shares in other permitted circumstances. The number of shares beneficially owned by selling shareholders who transfer, donate, pledge or grant a security interest in their shares will decrease as and when the selling shareholders take these actions. The plan of distribution for the shares offered and sold under this prospectus will otherwise remain unchanged, except that the permitted transferees, donees or other successors in interest will be selling shareholders for purposes of this prospectus. The selling shareholders may use brokers, dealers, underwriters or agents to sell their shares. The persons acting as agents may receive compensation in the form of commissions, discounts or concessions. This compensation may be paid by the selling shareholders or the purchasers of the shares for whom such persons may act as agent, or to whom they may sell as principal, or both. The compensation as to a particular person may be less than or in excess of customary commissions. The selling shareholders and any agents or broker-dealers that participate with the selling shareholders in the offer and sale of the shares may be deemed to be "underwriters" within the meaning of the Securities Act. Any commissions they receive and any profit they realize on the resale of the shares by them may be deemed to be underwriting discounts and commissions under the Securities Act. Neither we nor any selling shareholders can presently estimate the amount of such compensation. If a selling shareholder sells shares in an underwritten offering, the underwriters may acquire the shares for their own account and resell the shares from time to time in one or more 5 transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. In such event, we will set forth in a supplement to this prospectus the names of the underwriters and the terms of the transactions, including any underwriting discounts, concessions or commissions and other items constituting compensation of the underwriters and broker-dealers. The underwriters from time to time may change any public offering price and any discounts, concessions or commissions allowed or reallowed or paid to broker-dealers. Unless otherwise set forth in a supplement, the obligations of the underwriters to purchase the shares will be subject to certain conditions, and the underwriters will be obligated to purchase all of the shares specified in the supplement if they purchase any of the shares. We intend to advise the selling shareholders that during such time as they may be engaged in a distribution of the shares, they are required to comply with Regulation M under the Exchange Act. With certain exceptions, Regulation M prohibits any selling shareholder, any affiliated purchasers and any broker-dealer or other person who participates in such distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase, any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. The foregoing restrictions may affect the marketability of the shares. We may agree to indemnify the selling shareholders against certain liabilities, including certain liabilities under the Securities Act. It is possible that a significant number of shares could be sold at the same time. Such sales, or the perception that such sales could occur, may adversely affect prevailing market prices for our common stock. We will bear all expenses (other than selling commissions, underwriting discounts and fees and expenses of counsel to any selling shareholder) of the selling shareholders in connection with the registration and sale of the shares pursuant to this registration statement. To the extent required, we will file during any period in which offers or sale are being made, one or more supplements to this prospectus to set forth the name of selling stockholders and any other material information with respect to the plan of distribution not previously disclosed. LEGAL MATTERS Certain legal matters relating to the validity of shares of our common stock offered pursuant to this prospectus will be passed upon for us by Krieg DeVault LLP, Indianapolis, Indiana. EXPERTS Our consolidated financial statements incorporated into this prospectus by reference to the Annual Report on Form 10-K for the year ended December 31, 2002 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, independent accountants, given on the authority of said firm as experts in auditing and accounting. 6
