Old National Bancorp (the "Company") is implementing several changes to the Old National Bancorp Employee Stock Ownership and Savings Plan (the "Plan"), including, among others, changing the provider of recordkeeping and plan administration services and the trustee of the Plan as well as changing the participant-directed investment funds under the Plan. As a result, a blackout period with respect to participants' accounts will be in effect beginning at 2:30 p.m., Central Daylight Time, on September 25, 2006 and will end the week of October 16, 2006 (the "Blackout Period"), as described below.

Notice of the blackout period was provided to all participants and beneficiaries under the Plan on August 18, 2006. On September 8, 2006, the Company sent a notice to its directors and executive officers informing them of the blackout period. The notice also informed the directors and executive officers that, pursuant to Section 306(a) of the Sarbanes-Oxley Act of 2002, they would be prohibited from purchasing, selling or otherwise acquiring or transferring any common stock or other equity securities of the Company during the blackout period. A copy of the notice is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

A participant in the Plan, a security holder of the Company or other interested persons may obtain, without charge, information regarding the actual ending date of the blackout period by contacting Allen R. Mounts, Executive Vice President, Old National Bancorp, in writing at One Main Street, Evansville, Indiana 47708, or by telephone at (812) 464-1411.
