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 Quarterly Report on Form 10-Q, 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 FERC, the MPUC, the FPSC, the NCUC, the PSCW 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; - 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; - our 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. 3 ALLETE Third Quarter 2002 Form 10-Q

NOTE 2. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES AFC, through a wholly owned subsidiary, sells certain finance receivables through a revolving private securitization structure. On May 31, 2002 AFC and the subsidiary entered into a revised securitization agreement that allows for the revolving sale by the subsidiary to third parties of up to $500 million in undivided interests in eligible finance receivables. The revised agreement expires in 2005. The securitization agreement in place prior to May 31, 2002 limited the sale of undivided interests to $325 million. In accordance with SFAS 140 "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," which became applicable to AFC upon amendment of the securitization agreement, AFC, for accounting purposes, began consolidating the subsidiary used in the securitization structure on June 1, 2002. Previously, AFC's interest in this subsidiary was recorded by ALLETE as residual interest in other current assets ($103 million at December 31, 2001) net of the subsidiary's allowance for doubtful accounts. The residual interest previously reflected in prior periods has been reclassified by ALLETE to accounts receivable to conform to current year presentations. AFC managed total receivables of $535.2 million at September 30, 2002 ($500.2 million at December 31, 2001); $200.4 million represent receivables which were included in accounts receivable on our consolidated balance sheet ($233.2 million at December 31, 2001) and $334.8 million represent receivables sold in undivided interests through the securitization agreement ($267.0 million at December 31, 2001) which are off-balance sheet. AFC's proceeds from the sale of the receivables to third parties were used to repay borrowings from ALLETE and fund new loans to AFC's customers. AFC and the subsidiary must each maintain certain financial covenants such as minimum tangible net worth to comply with the terms of the securitization agreement. NOTE 3. GOODWILL AND OTHER INTANGIBLE ASSETS We adopted SFAS 142, "Goodwill and Other Intangible Assets," in January 2002 and, accordingly, no longer amortize goodwill. We completed the required goodwill impairment testing in the first quarter of 2002 with no resulting impairment. No event or change has occurred that would indicate the carrying amount has been impaired since our annual test. SFAS 142 requires disclosure of what reported net income and earnings per share would have been in all periods presented, exclusive of amortization expense recognized in those periods related to goodwill or other intangible assets that are no longer being amortized. All goodwill amortization related to continuing operations.

NOTE 4. DISCONTINUED OPERATIONS In September 2001 we began a process of systematically evaluating our businesses to determine the strategic value of our assets and explore ways to unlock that value. As a result, our management and Board of Directors committed to a plan to sell our Water Services businesses and our auto transport business. Water Services includes water and wastewater services operated by several wholly owned subsidiaries in Florida, North Carolina and Georgia. The financial results for all of these businesses have been accounted for as discontinued operations. Accordingly, we ceased depreciation of assets related to these businesses in the fourth quarter of 2001. Depreciation expense for the quarter ended September 30, 2001, was $2.2 million after-tax ($6.6 million after-tax for the nine months ended September 30, 2001). During the first half of 2002 we exited our nonregulated water subsidiaries, our auto transport business and our retail store. In September 2002 Florida Water entered into an agreement to sell its assets to FWSA, a governmental authority that was established by an interlocal agreement between the cities of Gulf Breeze and Milton, Florida. The total amount we expect to receive in the transaction is $433 million at closing and $74 million over the next three years. The gain on this transaction is estimated to be approximately $100 million after taxes and related costs, and is expected to be recognized over a four-year period as payments are received. Aggregate net cash proceeds to ALLETE are expected to be $260 million for the entire transaction, $190 million of which are expected to be received in 2002. Terms of the purchase agreement call for a closing by December 15, 2002, subject to FWSA being able to issue bonds for the purchase price and other conditions. Lawsuits seeking to halt the sale were initiated in October 2002 by two civic associations and by four local governments which had hoped to purchase Florida Water's assets through a competing buyer. Florida Water maintains that these lawsuits are without merit and will vigorously defend its pending sale to FWSA. The Company is unable to predict the outcome of these lawsuits. We are using an investment banking firm to facilitate the sale of Heater Utilities and Georgia Water Services and discussions with prospective buyers are in process. We expect to enter into agreements to sell these businesses in 2002 or 2003.

NOTE 7. TOTAL COMPREHENSIVE INCOME For the quarter ended September 30, 2002 total comprehensive income was $32.9 million ($22.2 million for the quarter ended September 30, 2001). For the nine months ended September 30, 2002 total comprehensive income was $110.9 million ($101.4 million for the nine months ended September 30, 2001). Total comprehensive income includes net income, unrealized gains and losses on securities classified as available-for-sale, changes in the fair value of an interest rate swap and foreign currency translation adjustments. NOTE 8. NEW ACCOUNTING STANDARDS SFAS 143, "Accounting for Asset Retirement Obligations," requires the recognition of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the carrying amount of the related long-lived asset is correspondingly increased. Over time, the liability is accreted to its present value and the related capitalized charge is depreciated over the useful life of the asset. SFAS 143 is effective for fiscal years beginning after June 15, 2002. Currently, decommissioning amounts collected in Minnesota Power's rates are reported in accumulated depreciation, which upon adoption of SFAS 143 by the Company will require a reclassification to a liability. We are reviewing what additional assets, if any, may have associated retirement costs as defined by SFAS 143 and anticipate no material impact on the Company's financial position and results of operations. On October 25, 2002 the FASB's Emerging Issues Task Force rescinded EITF Issue 98-10, "Accounting for Contracts Involved in Energy Trading and Risk Management Activities." The ruling takes effect January 1, 2003 for existing contracts and immediately for contracts entered into after October 25, 2002. In general, EITF 98-10 required energy trading contracts to be marked-to-market with resulting gains and losses recognized in income. Any gains or losses recognized under the provisions of EITF 98-10 through the end of 2002 will be reversed under the transitional provisions contained in the rescission. The Company was required to account for the Kendall County tolling agreement under EITF 98-10 which resulted in the recognition of $4.7 million of mark-to-market pre-tax income through the first nine months of 2002 ($0 in 2001). This agreement will be marked-to-market through the end of 2002. NOTE 9. SQUARE BUTTE POWER PURCHASE AGREEMENT Minnesota Power has a power purchase agreement with Square Butte that extends through 2026 (Agreement). It provides a long-term supply of low-cost energy to customers in our electric service territory and enables Minnesota Power to meet power pool reserve requirements. Square Butte, a North Dakota cooperative corporation, owns a 455-MW coal-fired generating unit (Unit) near Center, North Dakota. The Unit is adjacent to a generating unit owned by Minnkota, a North Dakota cooperative corporation whose Class A members are also members of Square Butte. Minnkota serves as the operator of the Unit and also purchases power from Square Butte. Minnesota Power is entitled to approximately 71 percent of the Unit's output under the Agreement. After 2005 and upon compliance with a two-year advance notice requirement, Minnkota has the option to reduce Minnesota Power's entitlement by 5 percent annually, to a minimum of 50 percent. Minnesota Power is obligated to pay its pro rata share of Square Butte's costs based on Minnesota Power's entitlement to Unit output. Minnesota Power's payment obligation is suspended if Square Butte fails to deliver any power, whether produced or purchased, for a period of one year. Square Butte's fixed costs consist primarily of debt service. At September 30, 2002 Square Butte had total debt outstanding of $298.8 million. Total annual debt service for Square Butte is expected to be approximately $36 million in each of the years 2002 and 2003, and $23 million in each of the years 2004 through 2006. Variable operating costs include the price of coal purchased from BNI Coal, Ltd., our subsidiary, under a long-term contract. Minnesota Power's payments to Square Butte are approved as purchased power expense for ratemaking purposes by both the MPUC and FERC. ALLETE Third Quarter 2002 Form 10-Q 12

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS ALLETE's core operations are focused on two business segments. ENERGY SERVICES includes electric and gas services, coal mining and telecommunications. AUTOMOTIVE SERVICES includes a network of wholesale and total loss vehicle auctions, a finance company, a vehicle remarketing company, a company that provides vehicle inspection services to the automotive industry and its lenders, and a company that provides Internet-based automotive parts location and insurance claim audit services nationwide. INVESTMENTS AND CORPORATE CHARGES includes our real estate operations, investments in emerging technologies related to the electric utility industry and corporate charges. Corporate charges represent general corporate expenses, including interest, not specifically related to any one business segment. Also included in Investments and Corporate Charges is our trading securities portfolio which was substantially liquidated during the third quarter of 2002. The liquidation process was completed in October 2002. DISCONTINUED OPERATIONS includes our Water Services businesses, our auto transport business and our retail store. CONSOLIDATED OVERVIEW Net income and earnings per share for the quarter ended September 30, 2002 increased 19 percent and 17 percent, respectively, from the same period in 2001. For the nine months ended September 30, 2002, net income increased 5 percent and earnings per share decreased 3 percent from the same period in 2001. The issuance of 6.6 million shares of our common stock in the second quarter of 2001 also impacted earnings per share. EXIT CHARGES. Net income for the nine months ended September 30, 2002 included $3.9 million of charges related to our exit from non-strategic businesses. Excluding these charges, earnings per share would have been $1.51 for the nine months ended September 30, 2002. GOODWILL. Earnings for the quarter ended September 30, 2001 included $2.7 million, or $0.03 per share, of goodwill amortization expense ($8.3 million, or $0.11 per share, for the nine months ended September 30, 2001). REAL ESTATE TRANSACTION. Earnings for the nine months ended September 30, 2001 included an $11.1 million, or $0.15 per share, gain associated with the Company's largest ever single real estate transaction.

NET INCOME The following net income discussion summarizes a comparison of the nine months ended September 30, 2002 to the nine months ended September 30, 2001. ENERGY SERVICES' net income in 2002 decreased $3.9 million, or 10 percent, primarily due to weak wholesale power prices. Earnings from retail electric operations remained strong as total retail megawatthour sales were up 4 percent from last year. Net income in 2001 reflected partial recovery of 1998 CIP lost margins. AUTOMOTIVE SERVICES reported a $19.6 million, or 33 percent, increase in net income and an 8 percent increase in EBITDAL over 2001. The continued growth in net income was due to mandated goodwill accounting changes, lower interest expense and improved operating efficiencies. In 2002 the number of vehicles sold at our wholesale auction facilities was similar to last year. Fleet downsizing by rental car companies after September 11, 2001 resulted in increased sales of factory vehicles at our auction facilities during the fourth quarter of 2001 to the detriment of 2002. Vehicle sales in other higher margin categories helped mitigate the reduction in sales of factory vehicles. Aggressive financing incentives offered by vehicle manufacturers lowered the cost of owning a new vehicle, which, in turn, depressed prices for late-model used vehicles. This reduced the number of vehicles sold at auctions because car dealers restocked their inventories from the increased volume of late-model vehicles traded in for new vehicles, and sellers at auction tended to hold their vehicles rather than immediately accept the lower prices. As a result, during the third quarter 2002 conversion rates (the percentage of vehicles sold from those that were offered at auction) began to drop. The conversion rate related to wholesale vehicles sold was 60 percent for 2002 (59 percent for 2001). Despite unseasonably dry weather conditions in 2002 which usually means fewer total loss vehicles, vehicles sold at our total loss vehicle auction facilities were up 27 percent in 2002 reflecting expansion into new markets, including combination sites with some of our wholesale auctions. AFC contributed 33 percent of the net income for Automotive Services in 2002 (36 percent in 2001) and reported a 6 percent increase in the number of vehicles financed. INVESTMENTS AND CORPORATE CHARGES reported $15.5 million less net income in 2002 primarily due to smaller real estate transactions in 2002. In June 2001 our real estate operations reported an $11.1 million gain on its largest single sale ever. The liquidation of our trading securities portfolio during the third quarter of 2002 also resulted in less net income. Our securities portfolio earned a negative 1.54 percent after-tax annualized return in 2002 compared to a positive 4.52 percent in 2001. DISCONTINUED OPERATIONS was up $5.7 million primarily due to the suspension of depreciation on our Water Services assets. Net income in 2001 included $6.6 million after-tax of depreciation expense. Our Water Services businesses also reported a 10 percent increase in water consumption as a result of drier weather conditions and a 5 percent increase in customers. These increases were partially offset by $3.9 million of exit charges associated with the auto transport business and the retail store. ALLETE Third Quarter 2002 Form 10-Q 14

COMPARISON OF THE QUARTERS ENDED SEPTEMBER 30, 2002 AND 2001 ENERGY SERVICES OPERATING REVENUE was up $3.4 million, or 2 percent, in 2002. Revenue from power marketing activities was $11.3 million higher in 2002 due to the inclusion of $17.4 million of revenue from merchant generation operations (non-rate base generation sold at market-based rates pursuant to FERC authority) which came online in 2002. The increase in revenue from power marketing activities, however, was negatively impacted by weak wholesale power prices in 2002. Revenue from retail electric sales increased $2.1 million in 2002 reflecting a 7 percent increase in total retail megawatthour sales. Revenue from our telecommunications business was down $4.4 million in 2002 because third quarter 2001 included nine months of operations from Enventis, Inc. which was acquired in July and accounted for as a pooling of interests. Revenue in 2001 included the recovery of $2.8 million of 1998 CIP lost margins. Revenue from electric sales to taconite customers accounted for 10 percent of consolidated operating revenue in both 2002 and 2001. Electric sales to paper and pulp mills accounted for 4 percent of consolidated operating revenue in both 2002 and 2001. Sales to other power suppliers accounted for 11 percent of consolidated operating revenue in 2002 (8 percent in 2001). OPERATING EXPENSES were up $4.0 million, or 3 percent, in 2002 reflecting the inclusion of merchant generation operations and the write off of costs associated with a canceled power plant project. These increases were partially offset by a $4.0 million decrease related to recoverable costs deferred in conjunction with the fuel adjustment clause. Operating expenses for our telecommunications business were $4.5 million lower in 2002 because third quarter 2001 included nine months of operations from Enventis, Inc. which was acquired in July and accounted for as a pooling of interests. AUTOMOTIVE SERVICES OPERATING REVENUE was up $4.6 million, or 2 percent, in 2002. At ADESA, 433,000 wholesale vehicles were sold in 2002 (429,000 in 2001). Aggressive financing incentives offered by vehicle manufacturers continued to negatively impact the number of vehicles coming to auction and the average auction prices of vehicles sold at auction (see Net Income-Automotive Services). A reduction in factory vehicles brought to auction was partially mitigated by stronger sales in other vehicle categories. At our total loss vehicle auctions, 41,000 vehicles were sold in 2002 (34,000 in 2001) an increase of 20 percent reflecting expansion into new markets, including combination sites with some of our wholesale auctions. Operating revenue from AFC was higher in 2002 reflecting a 6 percent increase in vehicles financed through its loan production offices. AFC financed approximately 237,000 vehicles in 2002 (223,000 in 2001) and managed total receivables of $535 million at September 30, 2002 ($497 million at September 30, 2001). OPERATING EXPENSES were down $3.0 million, or 2 percent, in 2002 primarily due to reduced interest expense ($3.7 million) as a result of lower interest rates, the discontinuance of goodwill amortization ($3.3 million) and improved operating efficiencies. These decreases were partially offset by an increase in operating expenses incurred to standardize operations at all of our total loss auction facilities and expenditures for information technology initiatives. INVESTMENTS AND CORPORATE CHARGES OPERATING REVENUE was down $1.1 million, or 13 percent, in 2002 primarily because our trading securities portfolio was substantially liquidated during the third quarter. Revenue from our real estate operations was down slightly compared to 2001. OPERATING EXPENSES were down $2.9 million, or 18 percent, in 2002 because in 2001 additional expenses were incurred for severance packages. 15 ALLETE Third Quarter 2002 Form 10-Q

COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 2002 AND 2001 ENERGY SERVICES OPERATING REVENUE was down $6.1 million, or 1 percent, in 2002 reflecting a $20.5 million decrease in revenue from power marketing activities due to lower wholesale power prices in 2002. This decrease was offset by the inclusion of $25.4 million of revenue from merchant generation operations which came online in 2002, and $4.8 million for mark-to-market income related to energy contracts in 2002 ($0.5 million in 2001). A $15.0 million decrease in revenue from retail electric and gas sales was attributed to lower fuel clause recovery due to lower fuel costs in 2002. Total retail megawatthour sales, however, were up 4 percent in 2002 reflecting increased usage by taconite customers. In addition, retail electric revenue in 2001 included the recovery of $2.8 million of 1998 CIP lost margins. Revenue from electric sales to taconite customers accounted for 10 percent of consolidated operating revenue in both 2002 and 2001. Electric sales to paper and pulp mills accounted for 4 percent of consolidated operating revenue in both 2002 and 2001. Sales to other power suppliers accounted for 7 percent of consolidated operating revenue in 2002 and 2001. OPERATING EXPENSES in 2002 were comparable to 2001. Purchased power expense was down $14.2 million in 2002 because prices paid for purchased power were lower and Company generation was up 5 percent. Purchased gas expense was lower in 2002 because prices paid in 2001 were at record highs. Operating expenses in 2002 also reflected a $4.0 million decrease related to recoverable costs deferred in conjunction with the fuel adjustment clause, the inclusion of merchant generation operations, higher expenses for our telecommunications business, and the write off of costs associated with a canceled power plant project. In 2001 the Company had higher plant maintenance expenses and additional costs incurred as a result of a severe ice storm. AUTOMOTIVE SERVICES OPERATING REVENUE was up $17.0 million, or 3 percent, in 2002. At ADESA, 1,348,000 wholesale vehicles were sold in 2002 (1,353,000 in 2001). Aggressive financing incentives offered by vehicle manufacturers continued to negatively impact the number of vehicles coming to auction and the average auction prices of vehicles sold at auction (see Net Income-Automotive Services). A reduction in factory vehicles brought to auction was partially mitigated by stronger sales in other vehicle categories. At our total loss vehicle auctions, 131,000 vehicles were sold in 2002 (103,000 in 2001) an increase of 27 percent reflecting expansion into new markets, including combination sites with some of our wholesale auctions. Operating revenue from AFC was higher in 2002 reflecting a 6 percent increase in vehicles financed through our loan production offices. AFC financed approximately 715,000 vehicles in 2002 (676,000 in 2001) and managed total receivables of $535 million at September 30, 2002 ($497 million at September 30, 2001). OPERATING EXPENSES were down $16.3 million, or 3 percent, in 2002 primarily due to reduced interest expense ($12.9 million) as a result of lower interest rates, the discontinuance of goodwill amortization ($9.9 million) and improved operating efficiencies. These decreases were partially offset by an increase in operating expenses incurred to standardize operations at all our total loss auction facilities and expenditures for information technology initiatives. INVESTMENTS AND CORPORATE CHARGES OPERATING REVENUE was down $35.4 million, or 55 percent, in 2002 primarily due to a large real estate transaction recorded in 2001. Four large real estate sales in 2002 contributed $7.4 million to revenue, while in 2001 six large real estate sales contributed $37.5 million to revenue, one of which was our real estate operations' largest single transaction ever. Operating revenue also reflected less income in 2002 from our trading securities portfolio which was substantially liquidated during the third quarter and had significantly lower returns during the year. OPERATING EXPENSES were down $11.4 million, or 21 percent, in 2002 primarily due to expenses associated with larger real estate sales in 2001. Also, in 2001 additional expenses were incurred for severance packages. ALLETE Third Quarter 2002 Form 10-Q 16

CRITICAL ACCOUNTING POLICIES Certain accounting measurements under applicable generally accepted accounting principles involve management's judgment about subjective factors and estimates, the effects of which are inherently uncertain. The following summarizes those accounting measurements we believe are most critical to our reported results of operations and financial condition.

Quantitative and Contracts energy supply, demand and market prices Qualitative Disclosures about - Wholesale power market conditions Market Risk - Power Marketing on page 21 OUTLOOK In September 2002 we revised our earnings per share estimate for 2002 to be in the range of $1.80 to $1.90 including the goodwill accounting change. This estimate excluded $0.05 per share of charges related to the exit from the auto transport business and the retail store, and any potential gain recognized on the sale of our Water Services businesses. Our recent adjustment in our earnings guidance reflected the liquidation of the trading securities portfolio and year to date weaker performance within our Energy Services segment due to continued lower-than-expected wholesale power prices. During the first few weeks of the fourth quarter, we experienced a notable drop in the conversion rates at our wholesale vehicle auctions which we believe was primarily influenced by vehicle manufacturers extending zero-percent financing into the 2003 model year. Aggressive financing incentives lowered the cost of owning a new vehicle, which, in turn, depressed prices for late-model used vehicles. This reduced the number of vehicles sold at auctions because car dealers restocked their inventories from the increased volume of late-model vehicles traded in for new vehicles, and sellers at auction tended to hold their vehicles rather than immediately accept the lower prices. We expect the sellers of used vehicles to ultimately begin selling again, but timing is uncertain. Based on current market conditions we believe Automotive Services will not achieve our stated earnings growth goal of 30 percent this year. We now expect ALLETE's earnings per share to be at the low end of the range with respect to our estimate for 2002. The cash generated from the liquidation of our trading securities portfolio as well as from our continuing operations and the expected sale of our Water Services' assets will be used to reduce debt and fund strategic initiatives. Our balance sheet remains strong. We continue to focus on our two core competencies-Energy Services and Automotive Services. We believe both are positioned well to produce earnings growth as their individual markets improve. ENERGY SERVICES. Earnings from our core retail electric business remain strong. Our generation costs, including our merchant generation, are competitive in the regions we serve. We are well positioned to recognize increased benefits from wholesale electric sales as market conditions improve. 17 ALLETE Third Quarter 2002 Form 10-Q

AUTOMOTIVE SERVICES. The performance of our Automotive Services business for the nine months ended September 30, 2002 has demonstrated our ability to drive efficiencies at our auctions acquired since January 2000 and to generate profits. We expect to continue EBITDAL and revenue improvement, and double digit earnings growth for 2003. We have not seen factory vehicle volume at our vehicle auctions return to normal levels as we anticipated. This, combined with the impact of aggressive financing incentives discussed above, has resulted in an unexpected recent drop in conversion rates making it likely we will not achieve our stated earnings growth goal of 30 percent this year. AFC's receivable portfolio continues to maintain its strong credit quality and contribution to net income. INVESTMENTS AND CORPORATE CHARGES. We anticipate net income from Investments and Corporate Charges to decline in 2002 due to the liquidation of our trading securities portfolio and, as expected, a lower contribution from our real estate operations. Our revised earnings estimate for 2002 reflects a $0.10 per share income reduction due to minimal contribution from our trading securities portfolio. We liquidated our trading securities portfolio to reduce our exposure to increased volatility in the securities market. Proceeds from the liquidation have been used to reduce debt. DISCONTINUED OPERATIONS. In September 2002 Florida Water agreed to sell its assets to FWSA, a governmental authority that was established by an interlocal agreement between the cities of Gulf Breeze and Milton, Florida. The total amount we expect to receive in the transaction is $433 million at closing and $74 million over the next three years. The gain on this transaction is estimated to be approximately $100 million after taxes and related costs, and is expected to be recognized over a four-year period as payments are received. Aggregate net cash proceeds are expected to be $260 million for the entire transaction, of which $190 million are expected to be received in 2002. Terms of the purchase agreement call for a closing by December 15, 2002, subject to FWSA being able to issue bonds for the purchase price and other conditions. Lawsuits seeking to halt the sale were initiated in October 2002 by two civic associations and by four local governments which had hoped to purchase Florida Water's assets through a competing buyer. Florida Water maintains that these lawsuits are without merit and will vigorously defend its pending sale to FWSA. The Company is unable to predict the outcome of these lawsuits. We are using an investment banking firm to facilitate the sale of Heater Utilities and Georgia Water Services and discussions with prospective buyers are in process. We expect to enter into agreements to sell these businesses in 2002 or 2003. LIQUIDITY AND CAPITAL RESOURCES CASH FLOW ACTIVITIES During the first nine months of 2002 cash flow from operating activities reflected strong operating results and continued focus on working capital management. Cash flow from operating activities was higher in 2002 due to the liquidation of the trading securities portfolio and the timing of the collection of certain finance receivables outstanding at December 31, 2001. Also, in 2001 additional trading securities were purchased with a portion of the proceeds from a common stock issuance. Cash flow from operations was also affected by a number of factors representative of normal operations. WORKING CAPITAL. Additional working capital, if and when needed, generally is provided by the sale of commercial paper. During the third quarter of 2002 we substantially liquidated our trading securities portfolio. The liquidation process was completed in October 2002. Proceeds have been used to reduce our debt. Approximately 4.8 million original issue shares of our common stock are available for issuance through Invest Direct, our direct stock purchase and dividend reinvestment plan. A substantial amount of ADESA's working capital is generated internally from payments for services provided. However, ADESA has arrangements to use proceeds from the sale of commercial paper issued by ALLETE to meet short-term working capital requirements arising from the timing of payment obligations to vehicle sellers and the availability of funds from vehicle purchasers. During the sales process, ADESA does not typically take title to vehicles. ALLETE Third Quarter 2002 Form 10-Q 18

AFC offers short-term on-site financing for dealers to purchase vehicles at auctions in exchange for a security interest in each vehicle. The financing is provided through the earlier of the date the dealer sells the vehicle or a general borrowing term of 30 to 45 days. AFC has arrangements to use proceeds from the sale of commercial paper issued by ALLETE to meet its short-term working capital requirements. AFC, through a wholly owned subsidiary, sells certain finance receivables through a revolving private securitization structure. On May 31, 2002 AFC and the subsidiary entered into a revised securitization agreement that allows for the revolving sale by the subsidiary to third parties of up to $500 million in undivided interests in eligible finance receivables. The revised agreement expires in 2005. The securitization agreement in place prior to May 31, 2002 limited the sale of undivided interests to $325 million. In accordance with SFAS 140 "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," which became applicable to AFC upon amendment of the securitization agreement, AFC, for accounting purposes, began consolidating the subsidiary used in the securitization structure on June 1, 2002. Previously, AFC's interest in this subsidiary was recorded by ALLETE as residual interest in other current assets ($103.0 million at December 31, 2001) net of the subsidiary's allowance for doubtful accounts. The residual interest previously reflected in prior periods has been reclassified by ALLETE to accounts receivable to conform to current year presentations. AFC managed total receivables of $535.2 million at September 30, 2002 ($500.2 million at December 31, 2001); $200.4 million represent receivables which were included in accounts receivable on our consolidated balance sheet ($233.2 million at December 31, 2001) and $334.8 million represent receivables sold in undivided interests through the securitization agreement ($267.0 million at December 31, 2001) which are off-balance sheet. AFC's proceeds from the sale of the receivables to third parties were used to repay borrowings from ALLETE and fund new loans to AFC's customers. AFC and the subsidiary must each maintain certain financial covenants such as minimum tangible net worth to comply with the terms of the securitization agreement. We provide up to $50 million in credit support to facilitate the power marketing activities of Split Rock Energy, and had $31.9 million in outstanding support at September 30, 2002 ($36.0 million at December 31, 2001). SECURITIES. In March 2001 ALLETE, ALLETE Capital II and ALLETE Capital III, jointly filed a registration statement with the SEC pursuant to Rule 415 under the Securities Act of 1933. The registration statement, which has been declared effective by the SEC, relates to the possible issuance of an aggregate amount of $500 million of securities which may include ALLETE common stock, first mortgage bonds and other debt securities, and ALLETE Capital II and ALLETE Capital III preferred trust securities, of which approximately $387 million remains available to be issued. ALLETE also previously filed a registration statement, which has been declared effective by the SEC, relating to the possible issuance of $25 million of first mortgage bonds and other debt securities. We may sell all or a portion of the remaining registered securities if warranted by market conditions and our capital requirements. Any offer and sale of the above mentioned securities will be made only by means of a prospectus meeting the requirements of the Securities Act of 1933 and the rules and regulations thereunder. INVESTMENTS. As investments in emerging technology companies are sold, we recognize a gain or loss. Our direct investment in the companies that have gone public, which we account for as available-for-sale securities, had a cost basis of approximately $10 million at September 30, 2002 and December 31, 2001. The aggregate market value of our investment in these companies at September 30, 2002 was $4 million ($17 million at December 31, 2001). We believe the decline in market value that has occurred since second quarter 2002 is temporary. We have the ability and intent to hold these investments until the market recovers. These investments provide us with access to developing technologies before their commercial debut, as well as potential financial returns. We view these investments as a source of capital for redeployment in existing businesses. 19 ALLETE Third Quarter 2002 Form 10-Q

CAPITAL REQUIREMENTS As a result of new construction and expansions at Automotive Services, consolidated capital expenditures for 2002 are now expected to be $235 million. Consolidated capital expenditures for the nine months ended September 30, 2002 totaled $138.4 million ($108.4 million in 2001). Expenditures for 2002 included $63.6 million for Energy Services and $39.6 million for Automotive Services. Expenditures for 2002 also included $35.2 million related to discontinued operations ($31.3 million to maintain our Water Services businesses while they are in the process of being sold; $3.9 million to buy previously leased auto transportation trucks). Internally generated funds were the primary source of funding for these expenditures. NEW ACCOUNTING STANDARDS SFAS 143, "Accounting for Asset Retirement Obligations," requires the recognition of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the carrying amount of the related long-lived asset is correspondingly increased. Over time, the liability is accreted to its present value and the related capitalized charge is depreciated over the useful life of the asset. SFAS 143 is effective for fiscal years beginning after June 15, 2002. Currently, decommissioning amounts collected in Minnesota Power's rates are reported in accumulated depreciation, which upon adoption of SFAS 143 by the Company will require a reclassification to a liability. We are reviewing what additional assets, if any, may have associated retirement costs as defined by SFAS 143 and anticipate no material impact on the Company's financial position and results of operations. On October 25, 2002 the FASB's Emerging Issues Task Force rescinded EITF Issue 98-10, "Accounting for Contracts Involved in Energy Trading and Risk Management Activities." The ruling takes effect January 1, 2003 for existing contracts and immediately for contracts entered into after October 25, 2002. In general, EITF 98-10 required energy trading contracts to be marked-to-market with resulting gains and losses recognized in income. Any gains or losses recognized under the provisions of EITF 98-10 through the end of 2002 will be reversed under the transitional provisions contained in the rescission. The Company was required to account for the Kendall County tolling agreement under EITF 98-10 which resulted in the recognition of $4.7 million of mark-to-market pre-tax income through the first nine months of 2002 ($0 in 2001). This agreement will be marked-to-market through the end of 2002. --------------------------- READERS ARE CAUTIONED THAT FORWARD-LOOKING STATEMENTS INCLUDING THOSE CONTAINED ABOVE, SHOULD BE READ IN CONJUNCTION WITH OUR DISCLOSURES UNDER THE HEADING: "SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995" LOCATED ON PAGE 3 OF THIS FORM 10-Q. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK SECURITIES PORTFOLIO During the third quarter of 2002 we substantially liquidated our trading securities portfolio. The liquidation process was completed in October 2002. Proceeds have been used to reduce our debt. At September 30, 2002 available-for-sale securities consisted of the common stock of publicly traded companies and a grantor trust established to fund certain employee benefits. Our trading securities portfolio had a fair value of $43.5 million at September 30, 2002 ($155.6 million at December 31, 2001). Our available-for-sale securities portfolio had a fair value of $15.5 million at September 30, 2002 ($26.5 million at December 31, 2001). FOREIGN CURRENCY Our foreign currency exposure is limited to the conversion of operating results of our Canadian subsidiaries and, therefore, we have not entered into any foreign exchange contracts to hedge the conversion of our Canadian operating results into United States dollars. ALLETE Third Quarter 2002 Form 10-Q 20

POWER MARKETING Minnesota Power purchases power for retail sales in our retail service territory and sells excess generation in the wholesale market. At the end of the second quarter of 2002 we had 500 MW of merchant generation (non-rate base generation sold at market-based rates pursuant to FERC authority) available for sale to the wholesale market. Our merchant generation includes 225 MW from our Taconite Harbor Energy Center in northern Minnesota that was acquired in October 2001. It also includes 275 MW of generation secured through a 15-year tolling agreement, which commenced in May 2002, with NRG Energy at the Kendall County facility near Chicago, Illinois. Under the Kendall County tolling agreement, the Company pays a fixed capacity charge for the right, but not the obligation, to utilize one 275 MW generating unit. We are responsible for arranging the natural gas fuel supply and are entitled to the electricity produced. Our strategy is to sell the majority of merchant generation through long-term contracts of various durations. The balance will be sold in the spot market, through short-term agreements. The services of Split Rock Energy may be utilized to broker or market merchant generation. We currently have two long-term forward capacity and energy contracts related to generation secured by the NRG Energy tolling agreement. Each is for 50 MW, with one having a 10-year term and the other a 15-year term. The services of Split Rock Energy are used to fulfill purchase requirements for retail load and to market excess generation. We own 50 percent of Split Rock Energy which was formed in 2000 with Great River Energy to provide us with least cost supply, maximize the value of our generation assets and maximize marketing revenue within prescribed limits. Split Rock Energy operates in the wholesale energy markets, and engages in marketing activities by entering into forward and option contracts for the purchase and sale of electricity. These contracts are primarily short-term in nature with maturities of less than one year. Although Split Rock Energy generally attempts to balance its purchase and sale positions, commodity price risk sometimes exists or is created. This risk is actively managed through a risk management program that includes policies, procedures and limits established by the Split Rock Energy Board of Governors. Revenue for the nine months ended September 30, 2002 included $4.8 million for mark-to-market income attributable to the power marketing activities of Split Rock Energy and our merchant generation operations ($0.5 million for the nine months ended September 30, 2001). Included in the $4.8 million of mark-to-market income in 2002 is $5.6 million of mark-to-market income for future fixed margins associated with the Kendall County contracts. On October 25, 2002 the FASB's Emerging Issues Task Force rescinded EITF Issue 98-10, "Accounting for Contracts Involved in Energy Trading and Risk Management Activities." The ruling takes effect January 1, 2003 for existing contracts and immediately for contracts entered into after October 25, 2002. In general, EITF 98-10 required energy trading contracts to be marked-to-market with resulting gains and losses recognized in income. Any gains or losses recognized under the provisions of EITF 98-10 through the end of 2002 will be reversed under the transitional provisions contained in the rescission.

ITEM 4. CONTROLS AND PROCEDURES We maintain a system of controls and procedures designed to provide reasonable assurance as to the reliability of the financial statements and other disclosures included in this report, as well as to safeguard assets from unauthorized use or disposition. We evaluated the effectiveness of the design and operation of our disclosure controls and procedures under the supervision and with the participation of management, including our chief executive officer and chief financial officer, within 90 days prior to the filing date of this report. Based upon that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are effective in timely alerting them to material information required to be included in our periodic SEC filings. No significant changes were made to our internal controls or other factors that could significantly affect these controls subsequent to the date of their evaluation. PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS Material legal and regulatory proceedings are included in the discussion of Other Information in Item 5. and are incorporated by reference herein. ITEM 5.

Form 8-K dated and filed September 19, 2002 Ref. Form 8-K dated and filed September 20, 2002 In September 2002 Florida Water agreed to sell its assets to FWSA, a governmental authority that was established by an interlocal agreement between the cities of Gulf Breeze and Milton, Florida. The total amount we expect to receive in the transaction is $433 million at closing and $74 million over the next three years. The gain on this transaction is estimated to be approximately $100 million after taxes and related costs, and is expected to be recognized over a four-year period as payments are received. Lawsuits seeking to halt the sale were initiated in October 2002 by two civic associations and by four local governments which had hoped to purchase Florida Water's assets through a competing buyer. Florida Water maintains that these lawsuits are without merit and will vigorously defend its pending sale to FWSA. The Company is unable to predict the outcome of these lawsuits. Ref. Page 14. - Table - Contract Status for Minnesota Power Large Power Customers In October 2002 Eveleth Mines LLC announced that only 30 percent of the plant's capacity for taconite production is on order for 2003 making financing for working capital uncertain and plant closure a possibility. For the nine months ended September 30, 2002, Eveleth Mines represented approximately 1 percent of ALLETE's consolidated operating revenue. In October 2002 U.S. Steel Corp. announced the sale of 80 percent of its taconite production facility in Mt. Iron, Minnesota to an entity formed by Apollo Management, LP, a venture capital firm in New York. We anticipate no effect on current taconite production estimates or Minnesota Power's large power contract with the facility. ALLETE Third Quarter 2002 Form 10-Q 22

Ref. Page 15. - Seventh Full Paragraph In August 2002 Rapids Power LLC announced that it had canceled plans to pursue construction of a state-of-the-art 225 megawatt combined-heat-and-power facility in Grand Rapids, Minnesota, because its cost is presently too high to support marketable electricity and lower mill steam costs. The announcement followed a decision last spring by Rapids Power to delay seeking a Certificate of Need permit, which would have led to further study of the project's feasibility. Rapids Power was a partnership between Rainy River Energy Corporation, a wholly owned subsidiary of the Company, and Blandin Paper Co., a subsidiary of UPM-Kymmene Corporation. Ref. Page 18. - Insert after Seventh Full Paragraph In May 2001 SWL&P received notice from the Wisconsin Department of Natural Resources (WDNR) that the City of Superior had found soil contamination on property adjoining a former Manufactured Gas Plant (MGP) site owned and operated by SWL&P's predecessors from 1889 to 1904. The WDNR requested an environmental investigation be initiated. The WDNR also issued SWL&P a Responsible Party letter in February 2002 to initiate tracking of the project in the WDNR database so that progress can be monitored. The environmental investigation is underway and the Company is unable to predict the outcome of this matter at this time. ITEM 6.
