CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT On August 20, 1998, AMCORE Financial, Inc. ("Registrant") engaged the accounting firm of KPMG Peat Marwick LLP (KPMG), as its independent accountants. KPMG replaces McGladrey & Pullen, LLP ("McGladrey") as of the date reported above. The change in the Registrant's independent accountants was the result of a formal proposal process involving three accounting firms. The change followed a decision by the Registrant to outsource its internal auditing function to McGladrey who in turn resigned as Registrant's independent accountants. The decision to change accountants was approved by the Registrant's Audit and Executive Committees of the Board of Directors. This filing amends the August 20, 1998 filing in order to clarify that McGladrey & Pullen, LLP, resigned as independent accountants of AMCORE Financial, Inc. effective August 20, 1998.
