Explanation of Responses:

1. The purpose of this amendment is to remove the "4" which appeared beside the "J" in the transaction code column of Table I in the original filing, and to remove the "X" from the "Form 4 Transactions Reported" box. The Form 5 was a voluntary filing, as the transaction reported is exempt from the reporting requirements.

2. Reflects the liquidation of all shares of the Issuer's common stock held by the First Oak Brook Stock Bonus Plan, a tax-qualified profit sharing plan, in order to facilitate the merger of such plan into the Issuer's tax-qualified plan.

3. Received in the Merger in exchange for an option to purchase 15,000 shares of FOBB common stock at an exercise price of $33.70 per share.

4. Received in the Merger in exchange for an option to purchase 16,500 shares of FOBB common stock at an exercise price of $29.42 per share.

5. Received in the Merger in exchange for an option to purchase 20,000 shares of FOBB common stock at an exercise price of $27.78 per share. The option vested in full upon completion of the Merger.
