SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 In connection with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, ALLETE is hereby filing cautionary statements identifying important factors that could cause ALLETE's actual results to differ materially from those projected in forward-looking statements (as such term is defined in the Private Securities Litigation Reform Act of 1995) made by or on behalf of ALLETE in this Form 8-K, in presentations, in response to questions or otherwise. Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions or future events or performance (often, but not always, through the use of words or phrases such as "anticipates," "believes," "estimates," "expects," "intends," "plans," "projects," "will likely result," "will continue" or similar expressions) are not statements of historical facts and may be forward-looking. Forward-looking statements involve estimates, assumptions, risks and uncertainties and are qualified in their entirety by reference to, and are accompanied by, the following important factors, which are difficult to predict, contain uncertainties, are beyond the control of ALLETE and may cause actual results or outcomes to differ materially from those contained in forward-looking statements: - war and acts of terrorism; - prevailing governmental policies and regulatory actions, including those of the United States Congress, state legislatures, the Federal Energy Regulatory Commission, the Minnesota Public Utilities Commission, the Florida Public Service Commission, the North Carolina Utilities Commission, the Public Service Commission of Wisconsin and various county regulators, about allowed rates of return, financings, industry and rate structure, acquisition and disposal of assets and facilities, operation and construction of plant facilities, recovery of purchased power and capital investments, and present or prospective wholesale and retail competition (including but not limited to transmission costs) as well as general vehicle-related laws, including vehicle brokerage and auction laws; - unanticipated impacts of restructuring initiatives in the electric industry; - economic and geographic factors, including political and economic risks; - changes in and compliance with environmental and safety laws and policies; - weather conditions; - natural disasters; - market factors affecting supply and demand for used vehicles; - wholesale power market conditions; - population growth rates and demographic patterns; - the effects of competition, including the competition for retail and wholesale customers, as well as suppliers and purchasers of vehicles; - pricing and transportation of commodities; - changes in tax rates or policies or in rates of inflation; - unanticipated project delays or changes in project costs; - unanticipated changes in operating expenses and capital expenditures; - capital market conditions; - competition for economic expansion or development opportunities; - ALLETE's ability to manage expansion and integrate recent acquisitions; and - the outcome of legal and administrative proceedings (whether civil or criminal) and settlements that affect the business and profitability of ALLETE. Any forward-looking statement speaks only as of the date on which that statement is made, and ALLETE undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which that statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for management to predict all of those factors, nor can it assess the impact of each of those factors on the businesses of ALLETE or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement. 2 ALLETE Form 8-K dated March 14, 2003
