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 (Reform Act), the Company is hereby filing cautionary statements identifying important factors that could cause the Company's actual results to differ materially from those projected in forward-looking statements (as such term is defined in the Reform Act) made by or on behalf of the Company 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," "predicts," "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, 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 the Company and may cause actual results to differ materially from those contained in forward-looking statements: - prevailing governmental policies and regulatory actions, including those of Congress, state legislatures, the FERC, the MPUC, the FPSC, the NCUC and the PSCW, with respect to allowed rates of return, industry and rate structure, acquisition and disposal of assets and facilities, operation and construction of plant facilities, recovery of purchased power and other capital investments, and present or prospective wholesale and retail competition (including but not limited to retail wheeling and transmission costs); - economic and geographic factors including political and economic risks; - changes in and compliance with environmental and safety laws and policies; - weather conditions; - population growth rates and demographic patterns; - competition for retail and wholesale customers; - pricing and transportation of commodities; - market demand, including structural market changes; - changes in tax rates or policies or in rates of inflation; - changes in project costs; - unanticipated changes in operating expenses and capital expenditures; - capital market conditions; - competition for new energy development opportunities; and - legal and administrative proceedings (whether civil or criminal) and settlements that influence the business and profitability of the Company. Any forward-looking statement speaks only as of the date on which such statement is made, and the Company 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 these factors, nor can it assess the impact of each of these factors on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. iii

NOTE 2. REGULATORY MATTERS FLORIDA WATER 1991 RATE CASE REFUNDS. In 1995 the Florida First District Court of Appeals (Court of Appeals) reversed a 1993 FPSC order establishing uniform rates for most of Florida Water's service areas. With "uniform rates" all customers in each uniform rate area pay the same rates for water and wastewater services. In response to the Court of Appeals' order, in August 1996 the FPSC ordered Florida Water to issue refunds to those customers who paid more since October 1993 under uniform rates than they would have paid under stand-alone rates. This order did not permit a balancing surcharge to customers who paid less under uniform rates. Florida Water appealed, and the Court of Appeals ruled in June 1997 that the FPSC could not order refunds without balancing surcharges. In response to the Court of Appeals' ruling, the FPSC issued an order in January 1998 that did not require refunds. Florida Water's potential refund liability at that time was about $12.5 million, which included interest, to customers who paid more under uniform rates. In the same January 1998 order, the FPSC required Florida Water to refund, with interest, $2.5 million, the amount paid by customers in the Spring Hill service area from January 1996 through June 1997 under uniform rates which exceeded the amount these customers would have paid under a modified stand-alone rate structure. No balancing surcharge was permitted. The FPSC ordered this refund because Spring Hill customers continued to pay uniform rates after other customers began paying modified stand-alone rates effective January 1996 pursuant to the FPSC's interim rate order in Florida Water's 1995 Rate Case. The FPSC did not include Spring Hill in this interim rate order because Hernando County had assumed jurisdiction over Spring Hill's rates. In June 1997 Florida Water reached an agreement with Hernando County to revert prospectively to stand-alone rates for Spring Hill customers. Customer groups which paid more under uniform rates have appealed the FPSC's January 1998 order, arguing that they are entitled to a refund because the FPSC had no authority to order uniform rates. The Company has appealed the $2.5 million refund order. Initial briefs were filed by all parties in May 1998. In June 1998 the Court of Appeals reversed its previous ruling that the FPSC was without authority to order uniform rates at which time customer groups supporting the FPSC's January 1998 order filed a motion with the Court of Appeals seeking dismissal of the appeal by customer groups seeking refunds. Customers seeking refunds filed amended briefs in September 1998. A provision for refund related to the $2.5 million refund order was recorded in the third quarter of 1999. A decision is not expected before 2001. The Company is unable to predict the timing or outcome of the appeals process. NOTE 3.

ACQUISITIONS ADESA AUCTION FACILITIES. On June 20, 2000 ADESA acquired all of the outstanding common shares of Auction Finance Group, Inc. (AFG). AFG, which is headquartered in Miami, Florida, owns CAAG Auto Auction Holdings Ltd., a wholesale automotive remarketing company with locations throughout Canada, doing business as Canadian Auction Group. The transaction was accounted for using the purchase method which included an estimated allocation of the purchase price. Final purchase accounting adjustments are not expected to be material. Financial results have been included in the Company's consolidated financial statements since the date of purchase. Pro forma financial results have not been presented due to immateriality. This acquisition added 13 vehicle auction facilities and associated dealer financing business to ADESA's existing locations and established ADESA as the premier automotive services company in Canada. On May 31, 2000 ADESA Canada purchased the remaining 27 percent of Impact Auto. ADESA Canada acquired 20 percent of Impact Auto on October 1, 1995, 27 percent in March 1999 and another 26 percent in January 2000. The transaction was accounted for using the purchase method. Financial results have been included in the Company's consolidated financial statements since the date of each purchase. Pro forma financial results have not been presented due to immateriality. Impact Auto is Canada's largest national salvage auction chain with 11 sites in six provinces. Impact Auto provides remarketing services to insurance companies for their "total loss" vehicles. On February 7, 2000 ADESA purchased the Mission City Auto Auction in San Diego, California. The transaction was accounted for using the purchase method. Financial results have been included in the Company's consolidated financial statements since the date of purchase. Pro forma financial results have not been presented due to immateriality. The Mission City auction, which has been renamed ADESA San Diego, operates six auction lanes on 30 acres with full reconditioning facilities. The transactions described in the three preceding paragraphs had a combined purchase price of approximately $175.5 million and resulted in goodwill of $145.9 million, which the Company expects to amortize over a 40-year useful life. The Company funded these transactions with proceeds from the sale of ACE shares and proceeds from the sale of a portion of the Company's securities portfolio. SPRUCE CREEK SOUTH UTILITIES INC. On June 29, 2000 Florida Water purchased the assets of Spruce Creek for $5.5 million, plus a commitment to pay a fee for water connections through June 2005. The transaction was accounted for using the purchase method. Financial results have been included in the Company's consolidated financial statements since the date of purchase. Pro forma financial results have not been presented due to immateriality. Spruce Creek serves 3,100 water and 2,500 wastewater customers in three communities in Marion County, Florida. The systems acquired are designed to accommodate 10,000 customers. The Company funded this transaction with internally generated funds. -7-

NOTE 6. INVESTMENTS IN CAPITAL RE AND ACE In May 2000 Minnesota Power recorded a $30.4 million, or $0.44 per share, after-tax gain on the sale of the 4.7 million shares of ACE that Minnesota Power received in December 1999 when Capital Re merged with ACE. As a result of the merger, in 1999 Minnesota Power recorded a $36.2 million, or $0.52 per share, after-tax non-cash charge as follows: a $24.1 million, or $0.35 per share, charge in the second quarter following the merger agreement and discontinuance of Minnesota Power's equity accounting for Capital Re and a $12.1 million, or $0.17 per share, charge in the fourth quarter upon completion of the merger. NOTE 7. LONG-TERM DEBT On March 30, 2000 ADESA issued $35 million of 8.10% Senior Notes, Series B, due March 30, 2010. Proceeds were used to refinance short-term bank indebtedness incurred for the acquisition of vehicle auction facilities purchased in 1999 and for general corporate purposes. On June 22, 2000 Minnesota Power refinanced $4.6 million of 6.875% Pollution Control Revenue Refunding Bonds, Series 1991-A with $4.6 million of Adjustable Rate Pollution Control Revenue Refunding Bonds Series 2000 due December 1, 2015. The new bonds had an initial rate of 4.75%. On June 29, 2000 Heater issued an $8 million, 8.24%, note to COBANK, ACB, due June 20, 2025. Proceeds were used to refinance short-term indebtedness incurred for the 1999 acquisition of Mid South and capital improvements in 1999 and 2000. NOTE 8. PREFERRED STOCK In April 2000 the Company redeemed all 100,000 shares of Redeemable Serial Preferred Stock A, $7.125 Series for an aggregate of $10 million. Proceeds from the Company's securities portfolio were used to fund this redemption. NOTE 9. SQUARE BUTTE PURCHASED POWER CONTRACT The Company 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 the Company's electric service territory and enables the Company to meet power pool reserve requirements. Square Butte, a North Dakota cooperative corporation, owns a 455-megawatt coal-fired generating unit (Unit) near Center, North Dakota. The Unit is adjacent to a generating unit owned by Minnkota Power Cooperative, Inc. (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. The Company 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 the Company's entitlement by 5 percent annually, to a minimum of 50 percent. The Company is obligated to pay its pro rata share of Square Butte's costs based on the Company's entitlement to Unit output. The Company'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 June 30, 2000 Square Butte had total debt outstanding of $329.6 million. Total annual debt service for Square Butte is expected to be approximately $36 million in each of the years 2000 through 2003 and $23 million in 2004. Variable operating costs include the price of coal purchased from BNI Coal, a subsidiary of Minnesota Power, under a long-term contract. The Company's payments to Square Butte are approved as purchased power expense for ratemaking purposes by both the MPUC and FERC. -8-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS MINNESOTA POWER is a multi-services company with operations in four business segments: (1) ELECTRIC SERVICES, which include electric and gas services, coal mining and telecommunications; (2) AUTOMOTIVE SERVICES, which include a network of vehicle auctions, a finance company, an auto transport company, a vehicle remarketing company and a company that provides field information services; (3) WATER SERVICES, which include water and wastewater services; and (4) INVESTMENTS, which include a securities portfolio, intermediate-term investments and real estate operations. Corporate charges represent general corporate expenses, including interest, not specifically related to any one business segment. CONSOLIDATED OVERVIEW For the quarter and six months ended June 30, 2000 the Company reported continued strong performance across all business segments. Significant acquisitions and growth in Automotive Services and the performance of Investments contributed to higher operating results in 2000. Excluding the Capital Re and ACE transactions (see net income discussion for Investments below), net income for the second quarter of 2000 increased 30 percent over the second quarter of 1999 and net income for the six months ended June 30, 2000 increased 37 percent over the same period in 1999. Excluding the Capital Re and ACE transactions, earnings per share were $0.48 for the second quarter of 2000, an increase of 30 percent over the second quarter of 1999 and earnings per share were $0.91 per share for the six months ended June 30, 2000, a 36 percent increase over the same period in 1999.

(See Note 6.) Including the $24.1 million non-cash charge associated with the Capital Re transaction, net income from Investments was a $17.7 million loss for the quarter ended June 30, 1999 and a $14.8 million loss for the six months ended June 30, 1999. (See Note 6.) -9-

NET INCOME The following net income discussion summarizes significant events for the six months ended June 30, 2000. ELECTRIC SERVICES reflected stable net income in 2000 with growth in megawatthour sales offset by associated expenses. AUTOMOTIVE SERVICES reported higher net income in 2000 due to increased sales activity at ADESA auctions facilities and increased financing activity at AFC's loan production offices. During 2000 ADESA acquired or opened 16 new vehicle auction facilities, completed the acquisition of 11 salvage auction facilities and announced plans to purchase 9 additional vehicle auction facilities in the third quarter of 2000. WATER SERVICES generated higher net income in 2000 due to increased water consumption as a result of drier weather conditions and customer growth. Net income in 2000 also reflected higher rates approved by the FPSC in 1999. INVESTMENTS reported higher net income in 2000 because of significant sales by the Company's real estate operations, improved returns on the Company's securities portfolio and gains on intermediate-term investments in emerging technologies relating to the electric industry. In May 2000 Minnesota Power recorded a $30.4 million, or $0.44 per share, after-tax gain on the sale of the 4.7 million shares of ACE that Minnesota Power received in December 1999 when Capital Re merged with ACE. As a result of the merger, in 1999 Minnesota Power recorded a $36.2 million, or $0.52 per share, after-tax non-cash charge as follows: a $24.1 million, or $0.35 per share, charge in the second quarter following the merger agreement and discontinuance of Minnesota Power's equity accounting for Capital Re and a $12.1 million, or $0.17 per share, charge in the fourth quarter upon completion of the merger. COMPARISON OF THE QUARTERS ENDED JUNE 30, 2000 AND 1999 OPERATING REVENUE ELECTRIC SERVICES operating revenue was up $3.6 million in 2000, even though total megawatthour sales were about the same as in 1999. Megawatthour sales from retail customers were 5 percent higher in 2000 and contributed $3.8 million more to revenue. The increase was primarily due to higher requirements from large industrial customers. Megawatthour sales from wholesale power marketing activities decreased 28 percent in 2000 and contributed $2.3 million less to revenue due to cooler weather in 2000. Non-regulated subsidiaries within Electric Services contributed $1.1 million more to revenue in 2000. Revenue from electric sales to taconite customers accounted for 13 percent of consolidated operating revenue in 2000 (14 percent in 1999). Electric sales to paper and pulp mills accounted for 5 percent of consolidated operating revenue in both 2000 and 1999. Sales to other power suppliers accounted for 6 percent of consolidated operating revenue in 2000 (8 percent in 1999). AUTOMOTIVE SERVICES operating revenue was up $25.7 million in 2000 primarily due to a 14 percent increase in vehicles sold through ADESA auction facilities and a 16 percent increase in the number of vehicles financed at AFC loan production offices. At ADESA auction facilities 307,000 vehicles were sold in 2000 (270,000 in 1999). The increase in vehicles sold was primarily attributable to new auctions acquired or opened in 1999 and 2000. Financial results for 2000 included three months of operations for one auction facility acquired in July of 1999, one auction facility acquired in February 2000 and two auction facilities opened in April 2000. Financial results for 2000 also reflected one month of operations for 11 salvage auctions acquired in May 2000 and a partial month of operations for 13 auction facilities acquired in June 2000. AFC financed approximately 202,000 vehicles in 2000 (175,000 in 1999). AFC had 86 loan production offices at June 30, 2000 (84 at June 30, 1999). WATER SERVICES operating revenue was up $1.8 million in 2000 because of a 10 percent increase in water consumption. Drier weather conditions, customer growth and the inclusion of water systems acquired during 1999 and early 2000 led to the increase in water consumption. In addition, revenue in 2000 was $0.3 million higher due to higher rates approved by the FPSC in 1999. -10-

INVESTMENTS operating revenue was up $16.8 million in 2000. Significant sales by the Company's real estate operations were the primary reason for the increase. In 2000 revenue from real estate operations was $15.1 million higher. The increase was primarily attributed to four large sales that contributed $13.1 million to revenue. Revenue from Investments was also higher due to $2.7 million of gains on intermediate-term investments in emerging technologies relating to the electric industry. OPERATING EXPENSES ELECTRIC SERVICES operating expenses were up $2.3 million in 2000 primarily due to increased fuel expense. Fuel expense was $5.8 million higher in 2000 because the Company paid higher prices for coal and generated 422,000, or 36 percent, more megawatthours. Purchased power expense was $3.0 million lower in 2000 because the Company purchased 411,000, or 37 percent, fewer megawatthours. During 1999 one of the Company's generating plants was down for scheduled maintenance which forced the Company to incur higher purchased power expense in 1999 to meet requirements. AUTOMOTIVE SERVICES operating expenses were up $21.9 million in 2000 primarily due to the inclusion of new vehicles auctions facilities acquired or opened in late 1999 and 2000. Increased sales activity at existing auction facilities and financing activity at the automobile dealer floorplan financing business also increased operating expenses in 2000. WATER SERVICES operating expenses were up $1.3 million in 2000 due to the inclusion of water systems acquired in the second quarter of 1999 and early 2000. INVESTMENTS operating expenses were up $6.6 million in 2000 due to the cost of property sold by the Company's real estate operations. INCOME (LOSS) FROM INVESTMENT IN CAPITAL RE AND RELATED DISPOSITION OF ACE Income (loss) from investment in Capital Re and related disposition of ACE reflected a $48 million gain on the disposition of ACE shares in 2000 and a $16.1 million non-cash charge associated with the loss on the Capital Re share exchange at June 30, 1999. INCOME TAX EXPENSE Income tax expense was up $14.6 million in 2000 primarily due to the gain on the disposition of ACE shares and increased operating income. In 1999 income tax expense included the recognition of $15.0 million of deferred taxes related to the Company's investment in Capital Re. COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2000 AND 1999 OPERATING REVENUE ELECTRIC SERVICES operating revenue was up $13.0 million in 2000 primarily due to a 5 percent increase in megawatthour sales. More sales from wholesale power marketing activities and higher requirements by large industrial customers led to the increase in megawatthour sales. Megawatthour sales from wholesale power marketing activities increased 6 percent in 2000 and contributed $2.1 million more to revenue, while megawatthour sales to industrial customers increased 5 percent in 2000 and contributed $4.4 million more to revenue. Residential and commercial megawatthour sales were up 2 percent in 2000 and contributed $1.8 million more to revenue. In addition, non-regulated subsidiaries within Electric Services contributed $1.9 million more to revenue in 2000. Revenue from electric sales to taconite customers accounted for 13 percent of consolidated operating revenue in 2000 (15 percent in 1999). Electric sales to paper and pulp mills accounted for 5 percent of consolidated operating revenue in both 2000 and 1999. Sales to other power suppliers accounted for 6 percent of consolidated operating revenue in 2000 (7 percent in 1999). -11-

AUTOMOTIVE SERVICES operating revenue was up $48.4 million in 2000 primarily due to a 14 percent increase in vehicles sold through ADESA auction facilities and a 23 percent increase in the number of vehicles financed at AFC loan production offices. At ADESA auction facilities 602,000 vehicles were sold in 2000 (530,000 in 1999). The increase in vehicles sold was primarily attributable to new auctions acquired or opened in 1999 and 2000. Financial results for 2000 included six months of operations for two auction facilities acquired in 1999, five months of operations for one auction facility acquired in February 2000 and three months of operations for two auction facilities opened in April 2000. Financial results for 2000 also reflected one month of operations for 11 salvage auctions acquired in May 2000 and a partial month of operations for 13 auction facilities acquired in June 2000. AFC financed approximately 397,000 vehicles in 2000 (323,000 in 1999). AFC had 86 loan production offices at June 30, 2000 (84 at June 30, 1999). WATER SERVICES operating revenue was up $5.4 million in 2000 because of a 13 percent increase in water consumption. Drier weather conditions, customer growth and the inclusion of water systems acquired during 1999 and early 2000 led to the increase in water consumption. In addition, revenue in 2000 was $0.5 million higher due to higher rates approved by the FPSC in 1999. INVESTMENTS operating revenue was up $46.0 million in 2000. Significant sales by the Company's real estate operations were the primary reason for the increase. In 2000 seven large sales contributed $31.9 million to revenue. Improved returns from the securities portfolio and the $6.3 million of gains on intermediate-term investments in emerging technologies relating to the electric industry also contributed to higher operating revenue from Investments in 2000. The Company's securities portfolio recorded an after-tax return of 6.02 percent in 2000 (3.32 percent in 1999). OPERATING EXPENSES ELECTRIC SERVICES operating expenses were up $12.0 million in 2000 primarily due to increased fuel and purchased power expenses. Fuel expense was $5.8 million higher in 2000 because the Company paid higher prices for coal and generated 418,000, or 15 percent, more megawatthours to support the higher requirements of industrial retail customers. Purchased power expense was $4.2 million higher in 2000 because of increased prices in the wholesale market and more megawatthours bought to meet MPEX's marketing activities in the first quarter of 2000. MPEX is the Company's wholesale power marketing division. AUTOMOTIVE SERVICES operating expenses were up $41.1 million in 2000 primarily due to the inclusion of new vehicles auctions facilities acquired or opened in 1999 and 2000. Increased sales activity at the auction facilities and financing activity at the automobile dealer floorplan financing business also increased operating expenses in 2000. WATER SERVICES operating expenses were up $4.1 million in 2000 due to the inclusion of water systems acquired in the second quarter of 1999 and early 2000. INVESTMENTS operating expenses were up $17.6 million in 2000 due to the cost of property sold by the Company's real estate operations. INCOME (LOSS) FROM INVESTMENT IN CAPITAL RE AND RELATED DISPOSITION OF ACE Income (loss) from investment in Capital Re and related disposition of ACE reflected a $48 million gain on the disposition of ACE shares in 2000 and a $16.1 million non-cash charge associated with the loss on the Capital Re share exchange at June 30, 1999. INCOME TAX EXPENSE Income tax expense was up $27.6 million in 2000 primarily due to the gain on the disposition of the ACE shares and increased operating income. In 1999 income tax expense included the recognition of $15.0 million of deferred taxes related to the Company's investment in Capital Re. -12-

OUTLOOK ELECTRIC SERVICES. As the electric industry continues to restructure, the contribution from Electric Services is expected to remain stable with a solid customer base. Approximately half of the electricity the Company sells is to Large Power Customers, primarily taconite producers, which have long-term all-requirements contracts. Approximately 80 percent of the ore consumed by integrated steel facilities in the Great Lakes region originates from five taconite customers of Minnesota Power. On May 24, 2000 LTV announced its intention to close permanently its taconite pellet operation in Hoyt Lakes, Minnesota because it is no longer able to provide taconite pellets of competitive quality or cost. The financial impact of the LTV closure on Minnesota Power is minimal because LTV is not a Large Power Customer. LTV plans to close in the summer of 2001. The domestic steel industry continues to face high levels of imported products. Through May 2000, finished steel imports, at 12,599,000 net tons, were 17 percent higher than in the same period in 1999 and remain on pace to exceed 30 million tons this year. In 1999 the United States imported 35,657,000 tons of steel, higher than any year except 1998. Overall steel prices remain somewhat depressed. On a national level, despite the high level of imports, the strong U.S. economy continues to help fuel demand for domestically produced steel. AUTOMOTIVE SERVICES. ADESA is the second largest and the fastest growing vehicle auction business in North America. In May 2000 ADESA purchased the remaining 27 percent ownership in Impact Auto, which added 11 salvage auctions to the Automotive Services segment. The June 2000 acquisition of AFG added 13 Canadian vehicle auction facilities and associated dealer financing business to ADESA and established ADESA as the premier automotive services company in Canada. The ADESA/Manheim transaction, which is scheduled to close in the third quarter of 2000, will add nine vehicle auction facilities to ADESA. These acquisitions are expected to increase the number of vehicles sold by 60 percent in the near term with additional growth potential in the future. ADESA currently owns (or leases) and operates 45 vehicle auction facilities throughout the United States and Canada. Once the Manheim transaction closes and operations begin at the Calgary auction, which is under construction, ADESA will have 55 vehicle auction facilities. By the end of 2000 AFC will exit 17 of the 21 ADT auctions where it now has loan production offices. AFC plans to continue to serve these areas from newly established loan production offices or from other existing offices. AFC does not anticipate that the relocations will have a material financial impact. LIQUIDITY AND CAPITAL RESOURCES CASH FLOW ACTIVITIES. Cash flow from operations during the six months ended June 30, 2000 reflected improved operating results and continued focus on working capital management. Cash from operating activities 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. In addition, securities investments can be liquidated to provide funds for reinvestment in existing businesses or acquisition of new businesses and approximately 6 million original issue shares of Common Stock are available for issuance through the DRIP. A substantial amount of ADESA's working capital is generated internally from payments for services provided. However, ADESA has arrangements to use the proceeds from the sale of commercial paper issued by the Company 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. AFC also has arrangements to use proceeds from the sale of commercial paper issued by the Company to meet its operational requirements. AFC offers short-term on-site financing for dealers to purchase vehicles at auctions in exchange for a security interest in those vehicles. 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 sells certain finance receivables on a revolving basis to a wholly owned, unconsolidated, qualified special purpose subsidiary. This subsidiary in turn sells, on a revolving basis, an undivided interest in eligible finance receivables, up to a maximum at any one time outstanding of $300 million, to third party -13-

purchasers under an agreement which expires at the end of 2002. At June 30, 2000 AFC had sold $333.1 million of finance receivables to the special purpose subsidiary ($296.8 million at December 31, 1999). Third party purchasers had purchased an undivided interest in finance receivables of $237 million from this subsidiary at June 30, 2000 ($225 million at December 31, 1999). Unsold finance receivables held by the special purpose subsidiary are recorded by AFC as residual interest at fair value. Fair value is based upon estimates of future cash flows, using assumptions that market participants would use to value such instruments, including estimates of anticipated credit losses over the life of the receivables sold; a discount rate was not used due to the short-term nature of the receivables sold. The fair value of AFC's residual interest was $79.5 million at June 30, 2000 ($57.6 million at December 31, 1999). Proceeds from the sale of the receivables were used to repay borrowings from the Company and fund vehicle inventory purchases for AFC's customers. Significant changes in accounts receivable and accounts payable balances at June 30, 2000 compared to December 31, 1999 were due to increased sales and financing activity at Automotive Services. Typically auction volumes are down during the winter months and in December because of the holidays. As a result, both ADESA and AFC had lower receivables and fewer payables at year end. SALE OF INVESTMENTS. In May 2000 Minnesota Power sold its 4.7 million shares of ACE. Minnesota Power received the ACE shares and $25 million in cash in December 1999 when Capital Re merged with ACE. Prior to the merger, Minnesota Power owned 7.3 million shares, or 20 percent, of Capital Re. The $127 million in proceeds from the sale of ACE shares and proceeds from the sale of a portion of the Company's securities portfolio were used to fund the acquisitions of AFG and Impact Auto. ACQUISITIONS. In February 2000 ADESA purchased the Mission City Auto Auction in San Diego, California. The Mission City auction, which has been renamed ADESA San Diego, operates six auction lanes on 30 acres with full reconditioning facilities. In May 2000 ADESA Canada purchased the remaining 27 percent of Impact Auto. ADESA Canada acquired 20 percent of Impact Auto on October 1, 1995, 27 percent in March 1999 and another 26 percent in January 2000. Impact is Canada's largest national salvage auction chain with 11 sites in six provinces. Impact Auto provides remarketing services to insurance companies for their "total loss" vehicles. In June 2000 ADESA acquired all of the outstanding common shares of AFG. AFG, which is headquartered in Miami, Florida, owns CAAG Auto Auction Holdings Ltd., a wholesale automotive remarketing company with locations throughout Canada, doing business as Canadian Auction Group. The acquisition of AFG added 13 vehicle auction facilities and associated dealer financing business to ADESA's existing locations and established ADESA as the premier automotive services company in Canada. The transactions described in the three preceding paragraphs had a combined purchase price of approximately $175.5 million. The Company funded these transactions with proceeds from the sale of ACE shares and proceeds from the sale of a portion of the Company's securities portfolio. In July 2000 ADESA signed a definitive agreement with Manheim to buy eight ADT auctions and one Manheim auction for $251 million. In January 2000 Manheim agreed to purchase 28 ADT auctions. Following FTC review of the Manheim/ADT transaction, Manheim agreed to sell the nine auctions ADESA intends to purchase. The ADESA/Manheim transaction is subject to approval by the FTC and satisfaction of various other customary conditions. Closing is anticipated in the third quarter of 2000. The Company expects to finance the transaction through the issuance of long-term debt. As a result of these transactions, by the end of 2000 AFC will exit 17 of the 21 ADT auctions where it now has loan production offices. AFC plans to continue to serve these areas from newly established loan production offices or from other existing offices. AFC does not anticipate that the relocations will have a material financial impact. In June 2000 Florida Water purchased the assets of Spruce Creek for $5.5 million, plus a commitment to pay fees for water connections through June 2005. Spruce Creek serves 3,100 water and 2,500 wastewater customers in three communities in Marion County, Florida. The systems acquired are designed to accommodate 10,000 customers. The Company funded this transaction with internally generated funds. -14-

LONG-TERM DEBT. In March 2000 ADESA issued $35 million of 8.10% Senior Notes, Series B, due March 30, 2010. Proceeds were used to refinance short-term bank indebtedness incurred for the acquisition of vehicle auction facilities purchased in 1999 and for general corporate purposes. In June 2000 Minnesota Power refinanced $4.6 million of 6.875% Pollution Control Revenue Refunding Bonds, Series 1991-A with $4.6 million of Adjustable Rate Pollution Control Revenue Refunding Bonds Series 2000 due December 1, 2015. The new bonds had an initial rate of 4.75%. In June 2000 Heater issued an $8 million, 8.24%, note to COBANK, ACB, due June 20, 2025. Proceeds were used to refinance short-term indebtedness incurred for the 1999 acquisition of Mid South and capital improvements in 1999 and 2000. On July 21, 2000 the Company filed a registration statement with the SEC pursuant to Rule 415 under the Securities Act of 1933 for an aggregate of $400 million of first mortgage bonds and debt securities. The registration statement has not yet been declared effective by the SEC. Any offer and sale of the first mortgage bonds and debt securities will be made only by means of a prospectus. PREFERRED STOCK. In April 2000 the Company redeemed all 100,000 shares of Redeemable Serial Preferred Stock A, $7.125 Series for an aggregate of $10 million. In July 2000 the Company redeemed all 100,000 shares of Redeemable Serial Preferred Stock A, $6.70 Series for an aggregate of $10 million. Proceeds from the sale of a portion of the Company's securities portfolio were used to fund these redemptions. In July 2000 the Company called all 113,358 outstanding shares of 5% Preferred Stock at $102.50 per share plus accrued and unpaid dividends of $0.75 per share. The redemption date is August 24, 2000. Internally generated funds will be used to fund this redemption. LEASES. In April 2000 leases for three ADESA auction facilities (Boston, Charlotte and Knoxville) were refinanced in a $28.4 million leveraged lease transaction. The new lease expires on April 1, 2010, but may be terminated after 2005 under certain conditions. Minnesota Power has guaranteed ADESA's obligations under the lease. CAPITAL REQUIREMENTS. Consolidated capital expenditures for the six months ended June 30, 2000 totaled $56.5 million ($42.7 million in 1999). Expenditures for 2000 included $20.4 million for Electric Services, $24.5 million for Automotive Services and $11.6 million for Water Services. Internally generated funds and the issuance of long-term debt were the primary sources of funding for these expenditures. NEW ACCOUNTING STANDARDS In June 1998 the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. (SFAS) 133, "Accounting for Derivative Instruments and Hedging Activities," as amended by SFAS 137, effective for fiscal years beginning after June 15, 2000. SFAS 133 establishes accounting and reporting standards requiring that every derivative instrument be recorded on the balance sheet as either an asset or liability measured at fair value. SFAS 133 requires that changes in the derivative's fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges allows a derivative's gains and losses to offset the related results on the hedged item. The Company currently believes it has only a limited amount of derivative activity and adoption of SFAS 133 is not expected to have a material impact on the Company's financial position and results of operations. ------------------------------ Readers are cautioned that forward-looking statements including those contained above, should be read in conjunction with the Company's disclosures under the heading: "SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995" located in the preface of this Form 10-Q. -15-

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The Company's securities portfolio has exposure to both price and interest rate risk. Investments held principally for near-term sale are classified as trading securities and recorded at fair value. Trading securities consist primarily of the common stock of publicly traded companies. In strategies designed to hedge overall market risks, the Company also sells common stock short. Investments held for an indeterminate period of time are classified as available-for-sale securities and also recorded at fair value.

Through May 2000, finished steel imports, at 12,599,000 net tons, were 17 percent higher than in the same period in 1999 and remain on pace to exceed 30 million tons this year. In 1999 the United States imported 35,657,000 tons of steel, higher than any year except 1998. Overall steel prices remain somewhat depressed. On a national level, despite the high level of imports, the strong U.S. economy continues to help fuel demand for domestically produced steel. Ref.

Split Rock shall market the excess Power available from MP's Generation Resources, including the purchase and resale of Power from non-Members, with the goal to maximize the economic value of MP's Generation Resources and reduce the cost to MP of serving MP's End-Use Loads. Split Rock may fulfill its obligations hereunder by contracting with MPEX under the Wholesale Marketing and Operating Services Agreement Between MPEX and Split Rock Energy LLC. Section 6.03. Purchase and Resale of Members' Excess Power. MP hereby grants to Split Rock the exclusive option to purchase for resale to non-Member customers any excess Power available from MP's Generation Resources, after deduction for the Power dispatched from those Generation Resources to serve MP's End-Use Loads, any existing MP Off-System Transactions, and any released energy available as a result of arrangements with MP's retail customers. The Power for any such sales to non-Members shall be dispatched as part of Split Rock's dispatch services under this AGREEMENT, and shall be sold by MP to Split Rock under MP's market-based rate tariff at the transfer price and under the terms and conditions agreed to by the Members. If Split Rock does not exercise its option hereunder to purchase excess Power from MP, MP shall have the right, consistent with its other obligations under this AGREEMENT, to separately enter into transactions with third parties for the sale of such excess Power. Section 6.04 Duration of Split Rock's Contracts to Supply Power to Non-Members.

As part of that process, MP shall prepare and submit to MAPP an application for a change in its MAPP membership status consistent with Split Rock's assumption of End-Use Load Obligation and Reliability Membership for MP's End-Use Loads and Generation Resources. Notwithstanding the foregoing, MP intends to participate in MAPP as a Transmission Owning Member. Section 7.02.1 Change in MAPP Membership Status. If, during the term of this AGREEMENT, (a) MP ceases to be a MAPP Member, (b) the MAPP Agreement is terminated or materially modified, (c) some or all of MAPP's functions and responsibilities are assumed under a successor or different organization or entity, all terms and conditions with respect to MAPP shall remain in force until new terms and conditions are mutually agreed upon by the Members. Section 7.03 Costs of MAPP Membership. The costs of Split Rock's application to and participation in MAPP shall be considered a Split Rock cost and shall be charged to MP and the other Members pursuant to this AGREEMENT. SECTION 8.

SECTION 9. TERMINATION Section 9.01 Notice of Termination. This AGREEMENT may be terminated by MP upon one year's notice of termination, provided, however, that such termination shall not take effect between May 1 and September 30 of any year. Termination will be effective on the first day of the month, and written notice of termination must be given at least one year prior to the first day of the month that MP intends for its notice to become effective and for the AGREEMENT to terminate. Upon termination in accordance with this Section 9.01, MP shall be excused and relieved of all obligations and liabilities under this AGREEMENT, except those liabilities incurred before the effective date of termination or as a result of the termination. Each Party shall use every reasonable effort to mitigate any damages resulting from a breach and/or termination of this AGREEMENT. Section 9.02 Effect of Termination. If, upon termination of this AGREEMENT, the Parties are unable to mutually agree as to the effects of termination, any dispute over the effects of termination shall be resolved through arbitration under Section 11 of this AGREEMENT. The Parties shall allocate the responsibility for purchase and sales obligations under Split Rock contracts outstanding as of termination in accordance with principles to be adopted and implemented by the Members. The termination of this AGREEMENT shall not discharge either Party from any obligation it owes to the other or to any other Member by reason of any transaction, cost, damage, expense, investment, or liability which shall occur or arise prior to such termination. The Parties intend that any such obligation owed (whether the same shall be known or unknown at the termination of this AGREEMENT) shall survive the termination of this AGREEMENT. -11-

Section 10.04 No Third Party Beneficiary. No provision of this AGREEMENT shall in any way inure to the benefit of any customer, or any other third party, so as to constitute any such person as a third party beneficiary under this AGREEMENT, or of any one or more of the terms hereof, or otherwise give rise to any cause of action in any person not a Party hereto.

Exhibit 10(b) 1800 M Street, N.W. [MORGAN, LEWIS Washington, D.C. 20036-5869 & BOCKIUS LLP LOGO] 202-467-7000 COUNSELORS AT LAW Fax: 202-467-7176 April 21, 2000 Mr. David P. Boergers Secretary Federal Energy Regulatory Commission 888 First Street, N.E. Washington, D.C. 20426 Re: Amended Filing in Docket No. ER00-1857-000 ------------------------------------------ Dear Mr. Boergers: Enclosed for filing are six copies of the response of Split Rock Energy LLC ("Split Rock") and Minnesota Power, Inc. ("MP"), to the deficiency letter issued on April 10, 2000, in regards to the above-referenced docket. Split Rock and MP respectfully request that the Commission shorten the time for responding to this filing, in an effort to permit Split Rock to become operational by May 1, 2000, the beginning of the Mid-Continent Area Power Pool ("MAPP") summer season. There have been no interventions to date in this proceeding. I. BACKGROUND On March 10, 2000, Split Rock submitted for filing an Application for Market-Based Rate Authority ("Market Rate Application"), along with a Market-Based Wholesale Power Sales Tariff ("Market Rate Tariff"). Split Rock is a limited liability company formed pursuant to the laws of Minnesota by MP and Great River Energy ("GRE"), a generation and transmission cooperative (collectively Split Rock's "Members"). The Members formed Split Rock to schedule and dispatch their combined generation resources to optimally meet their native load needs and obligations under power sales contracts with third parties, and to market their excess generation resources. In its Market Rate Application, Split Rock requested authorization to engage in wholesale bulk power sales at market-determined prices and to resell transmission services. Split Rock indicated that it will sell power to its Members and will buy the excess power of its Members Philadelphia Washington New York Los Angeles Miami Harrisburg Pittsburgh Princeton London Brussels Frankfurt Tokyo Singapore

[MORGAN, LEWIS Mr. David P. Boergers & BOCKIUS LLP LOGO] April 21, 2000 Page 2 for resale, at negotiated rates under the proposed Market Rate Tariff. Split Rock will also purchase power from third parties as necessary to optimally serve the Members' native load needs and obligations under power sales contracts. Split Rock explained that it will function in much the same way as a cooperative, in that it will not retain net revenues, but instead will periodically disburse any profits to the Members. Split Rock's Market Rate Application indicated that MP committed to treating revenues flowing through Split Rock, the same as if the revenues were obtained directly by MP. In other words, like a cooperative, Split Rock is owned by those who use its joint dispatch and marketing services - MP and GRE - and any profits flow back to its owners, MP and GRE. Again, MP has committed to treating revenues from Split Rock as if they were earned within the utility. Due to the "cooperative-like" structure of Split Rock vis-a-vis its Members, there is no need for Split Rock to commit not to transact with its affiliates MP and GRE, nor is there a need for a code of conduct to govern the interactions or relationships between Split Rock and its Members. On April 10, 2000, Mr. Michael C. McLaughlin, Director, Division of Corporate Applications, issued a deficiency letter regarding Split Rock's Market Rate Application. The letter requested that Split Rock provide additional information about the affiliate relationships noted above. Specifically, the letter requested that Split Rock explain why MP is a cooperative, and requested that Split Rock respond to two scenarios specified in the letter. II. SPLIT ROCK'S AMENDED FILING Split Rock and its Members have spent considerable time and effort to ensure that captive customers will not be adversely affected by affiliate transactions. As explained in further detail below, Split Rock retains no profits at its level, but rather regularly distributes any profits to its Members MP and GRE. MP has expressly committed to treat revenues from Split Rock as if they were earned within MP, and as such, there is no opportunity for such revenues to be diverted to MP's shareholders. Ratepayers will benefit from the revenues in the same manner as if such revenues were obtained directly by MP. A. Transactions Between MP and Split Rock Will Not Adversely --------------------------------------------------------- Affect MP's Ratepayers ---------------------- The deficiency letter first asks for a detailed explanation as to why MP is a cooperative and how its customers are the cooperative's owners, and are not captive ratepayers. MP is a traditional investor-owned utility, and neither Split Rock nor MP contends that MP is a cooperative. Split Rock does contend that Split Rock itself, although not a cooperative, is

[MORGAN, LEWIS Mr. David P. Boergers & BOCKIUS LLP LOGO] April 21, 2000 Page 3 structured like a cooperative, and that this structure eliminates any concerns about affiliate abuse. In the traditional case where a power marketer is seeking to transact with its affiliated public utility, the Commission is concerned that the power marketer and the affiliated utility may transact in ways that result in a transfer of benefits from the affiliated utility (and its ratepayers), to the affiliated power marketer (and its shareholders). See, e.g., GS Electric Generating Corp., Inc., 81 FERC Paragraph 61,042 (1997). For example, the utility may purchase power from its affiliated marketer at higher-than-market rates, or sell power to its affiliated power marketer at lower-than-market rates - at the expense of the utility's ratepayers - in exchange for other benefits which are not passed on to the utility's ratepayers. See, e.g., Hinson Power Co., 72 FERC Paragraph 61,190, at 61,911 (1995). In the case of cooperatives, however, this concern is not present because the cooperative's owners are also its ratepayers; thus, any profits or benefits inuring to the cooperative are passed through automatically to the ratepayer/owners. See, e.g., Hinson, 72 FERC Paragraph 61,190, at 61,911. Here, Split Rock is wholly-owned by its sole Members MP and GRE, who are also the recipients of Split Rock's joint dispatch and power marketing services. Split Rock is essentially a service entity for its Members. Split Rock does not have any "shareholders" separate and apart from these Members. Although Split Rock will sell power to its Members, all sales by Split Rock to a Member will be priced based on Split Rock's cost, and Split Rock will not earn any margins on power sales to Members. Because Split Rock will not earn any margin on sales of power to MP, no revenues of MP will be diverted to Split Rock. MP's ratepayers will thus be indifferent as to whether MP purchases power from Split Rock, or directly from an unaffiliated third party. Likewise, although Split Rock will also purchase power from its Members, all of Split Rock's purchases from MP and GRE will be priced based on a transfer pricing methodology agreed to and developed by the Members, which is intended to track market prices. Split Rock may sell power purchased from MP or GRE, to third parties at a price that differs slightly from the price paid by Split Rock to MP or GRE. However, Split Rock will not retain any profits earned from such transactions. Rather, all profits obtained by Split Rock will be regularly distributed to its Members, MP and GRE. Accordingly, Split Rock is structured like a cooperative, in that its Member-owners are also its customers, and any profits earned by Split Rock will be regularly disbursed to its Member-owners, MP and GRE. As noted, MP has expressly committed to treat such revenues from Split Rock as if they were revenues earned by MP. MP's ratepayers will not be adversely

[MORGAN, LEWIS Mr. David P. Boergers & BOCKIUS LLP LOGO] April 21, 2000 Page 4 affected by Split Rock's involvement in transactions with its Members. Split Rock is simply a joint dispatch and power marketing organization, created to provide its Members with the economic benefits of jointly dispatching and marketing their combined resources. B. Examples of Transactions ------------------------ The letter also requests that Split Rock address two specific examples of transactions and revenue flows. Split Rock will address each of these examples in turn. (1) Purchases by MP: "If MP purchases power at market-based rates from Split Rock at a price that is above the prevailing market, explain why this transaction will not adversely affect MP's captive ratepayers. In your example, trace the stream of revenues from MP to Split Rock, back to MP and its captive ratepayers." The short answer is that MP's ratepayers and shareholders will be in precisely the same position as if MP made the purchase from the market. Split Rock's involvement in a purchase transaction for one of its Members is similar to that of a broker. Split Rock purchases power and resells it to the Member at the same price paid by Split Rock. There is no mark-up for such purchases, and Split Rock's administrative and other non-power costs of the transaction are recovered separately through its dispatch agreements with its Members. To the extent Split Rock buys power at a price higher than a perceived market price, the result is the same as if MP had made such a purchase itself. This should not occur, however, as under the pricing methodology established by the Members, the Members have the right to the lowest-cost energy purchased by Split Rock. Accordingly, Split Rock will not earn any margins from sales to MP. The results will be the same as if MP had entered into a transaction directly with a third party, leaving MP's ratepayers indifferent as to whether MP purchases power from Split Rock, or directly from unaffiliated third parties. (2) Purchases by Split Rock: "If Split Rock purchases power at market-based rates from MP at a price that is below the prevailing market, explain why this transaction will not adversely affect MP's captive ratepayers. In your example, trace the stream of revenues and describe the impact this transaction will have on MP's captive ratepayers." The pricing methodology developed by the Members for purchases by Split Rock from MP or GRE, combines a regional day-ahead market index with Split Rock's actual market experience.

[MORGAN, LEWIS Mr. David P. Boergers & BOCKIUS LLP LOGO] April 21, 2000 Page 5 Accordingly, the price paid by Split Rock to MP for power may differ from the price obtained by Split Rock upon resale, because the market price will not reflect the market index factor upon which the price paid by Split Rock to MP is based. In the event that the price paid by Split Rock to MP for power is below the prevailing market price subsequently obtained by Split Rock, however, Split Rock does not retain the difference. Rather, as discussed above in Section II.A, any Split Rock profit will be disbursed to the Members, MP and GRE. Although a portion of Split Rock profits from sales of power originally purchased from MP may go to GRE, the sharing of profits will also work to MP's benefit: MP will receive a similar share of any Split Rock profits obtained from sales of power which Split Rock originally purchased from GRE. As noted, MP will treat such disbursements from Split Rock as if they were obtained directly through MP as utility revenues. C. Overall Benefits of Split Rock ------------------------------ Although the April 10, 2000 letter did not ask that MP or Split Rock describe the anticipated benefits of Split Rock, Split Rock's activities are expected to result in significant savings to MP's ratepayers. The economic dispatch of the Members' combined generation resources will result in increased operational efficiencies. Further, Split Rock will engage in marketing on behalf of its Members, with the goal of optimizing the value of their resources. Split Rock will also engage in power trading transactions with third parties, and MP will receive its proportionate share of Split Rock's profits from its power trading activities. As noted, MP has committed to treat all revenues obtained from Split Rock as utility revenues. Overall, the Members anticipate that Split Rock's economic dispatch, marketing, and power trading activities will result in significant cost savings and economic benefits to MP, and to MP's ratepayers. III. REQUEST FOR EXPEDITED NOTICE AND COMMENT PERIOD As noted in the Market Rate Application, Split Rock and its Members desire Split Rock to commence commercial operations on May 1, 2000, the beginning of the MAPP summer season. Accordingly, Split Rock requested waiver of the standard 60-day notice requirement to permit its Market Rate Tariff to become effective as a rate schedule as of May 1, 2000. Such an effective date will allow Split Rock to engage in transactions under the Market Rate Tariff as soon as it begins operations, and to begin its joint dispatch and marketing functions on behalf of the Members for the full upcoming MAPP summer season. Split Rock respectfully requests that the Commission issue the attached notice of amendment no later than April 24, 2000, and that the Commission provide that comments must be received

[MORGAN, LEWIS Mr. David P. Boergers & BOCKIUS LLP LOGO] April 21, 2000 Page 6 no later than April 28, 2000. This will allow the Commission to issue its order as soon as possible. A notice of filing of amendment suitable for publication in the Federal Register and a copy of the notice on diskette are also included. In the event additional information is needed, please contact either of the undersigned. Sincerely, /s/ Kristina E. Beard John D. McGrane Kristina E.
