CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANTS (a) Previous Independent Public Accountants Effective March 9, 1999, the Board of Directors of Firstar Corporation, a Wisconsin corporation (the "Registrant") dismissed Arthur Andersen LLP ("Arthur Andersen") as its independent public accountants. The Audit Committee of the Board of Directors of the Registrant approved this action. Arthur Andersen had been engaged to audit the financial statements of Star Banc Corporation, an Ohio corporation ("Star"), prior to the consummation of the merger of Star and the Registrant (the "Merger") on November 20, 1998. In connection with the audits of Star's financial statements as of December 31, 1997 and 1996 and for the years then ended and through the period November 20, 1998, there were no disagreements between Star and Arthur Andersen on any matters of accounting principles or practices, financial statements disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Arthur Andersen, would have caused it to make a reference to the subject matter of the disagreements in connection with its reports on financial statements. Arthur Andersen's reports on Star's financial statements as of December 31, 1997 and 1996 contained no adverse opinion or disclaimer of opinion, and was not qualified or modified as to uncertainty, audit scope or accounting principle. Upon the consummation of the Merger, the Board of Directors of the Registrant engaged Arthur Andersen as of November 20, 1998 to audit the Consolidated Balance Sheets as of December 31, 1998 and 1997 and the Consolidated Statements of Income, Shareholders' Equity and Cash Flows for each of the three years in the period ended December 31, 1998. During the interim period between November 20, 1998 and March 9, 1999, there were no disagreements between the Registrant and Arthur Andersen on any matters of accounting principles or practices, financial statements disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Arthur Andersen, would have caused it to make a reference to the subject matter of the disagreements in connection with its reports on financial statements. The Registrant has provided a copy of this disclosure to Arthur Andersen in compliance with the provisions of Item 304(a)(3) of Regulation S-K and has requested a letter from Arthur Andersen addressed to the Securities and Exchange Commission stating that Arthur Andersen agrees with the statements as set forth above. A copy of that letter, dated March 11, 1999, is attached as Exhibit 16.1 to this Current Report on Form 8-K.

The Board of Directors of the Registrant also announced that holders of record of Firstar Common Stock on March 31, 1999 will be paid a regular quarterly dividend of $0.30 per share on April 15, 1999 based on their pre-split shares of Firstar Common Stock.
