(a) Previous Independent Registered Public Accounting Firm On March 15, 2005, the Minnesota Power and Affiliated Companies Retirement Savings and Stock Ownership Plan (RSOP) dismissed PricewaterhouseCoopers LLP (PricewaterhouseCoopers) as its independent registered public accounting firm. ALLETE, Inc., the sponsoring employer and plan administrator of the RSOP, continues to engage PricewaterhouseCoopers as its independent registered public accounting firm. The decision to change independent registered public accounting firms was approved by the Employee Benefit Plans Committee of the RSOP. The reports of PricewaterhouseCoopers on the financial statements of the RSOP for the years ended December 31, 2003 and 2002, did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principle. During the years ended December 31, 2003 and 2002, and through March 15, 2005, there have been no disagreements with PricewaterhouseCoopers on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PricewaterhouseCoopers, would have caused PricewaterhouseCoopers to make reference thereto in their reports on the financial statements for such years. During the years ended December 31, 2003 and 2002, and through March 15, 2005, there were no "reportable events," as that term is defined in Item 304(a)(1)(v) of Regulation S-K. A copy of the foregoing disclosures was provided to PricewaterhouseCoopers prior to the date of the filing of this report. PricewaterhouseCoopers has furnished the RSOP a copy of the letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the statements above. A copy of PricewaterhouseCoopers' letter, dated March 18, 2005, is filed as Exhibit 16 to this Form 8-K.

During the years ended December 31, 2003 and 2002, and through March 15, 2005, RSOP did not consult with Reilly, Penner & Benton regarding any of the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.
